CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS AND INDUSTRY DATA

This Annual Report on Form 10-K contains forward-looking statements about us and our industry that involve substantial risks and uncertainties. 
All statements other than statements of historical facts contained in this Annual Report on Form 10-K, including statements regarding our strategy, future 
financial condition, future operations, research and development, planned clinical trials and preclinical studies, technology platforms, the timing and 
likelihood of regulatory filings and approvals for our product candidates, our ability to commercialize our product candidates, the potential benefits of 
collaborations, projected costs, prospects, plans, objectives of management and expected market growth, the timing of availability of clinical data, program 
updates and data disclosures, the ability of sotrovimab to treat and/or prevent COVID-19, the expected number of therapeutic doses that Vir will be able to 
supply to patients, and the ability of sotrovimab to maintain activity against circulating variants of concern and interest are forward-looking statements. In 
some cases, you can identify forward-looking statements by terminology such as “aim,” “anticipate,” “assume,” “believe,” “contemplate,” “continue,” 
“could,” “design,” “due,” “estimate,” “expect,” “goal,” “intend,” “may,” “objective,” “plan,” “positioned,” “potential,” “predict,” “seek,” “should,” 
“target,” “will,” “would” and other similar expressions that are predictions of or indicate future events and future trends, or the negative of these terms or 
other comparable terminology.

We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we 

believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements are subject to a 
number of known and unknown risks, uncertainties and assumptions described in the sections titled “Risk Factors” and “Management’s Discussion and 
Analysis of Financial Condition and Results of Operations” and elsewhere in this report. Other sections of this report may include additional factors that 
could harm our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors 
emerge from time to time, and it is not possible for our management to predict all risk factors nor can we assess the impact of all factors on our business or 
the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in, or implied by, any forward-
looking statements.

In light of the significant uncertainties in these forward-looking statements, you should not rely upon forward-looking statements as predictions of 
future events. Although we believe that we have a reasonable basis for each forward-looking statement contained in this report, we cannot guarantee that 
the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur at all. 
You should refer to the section titled “Risk Factors” for a discussion of important factors that may cause our actual results to differ materially from those 
expressed or implied by our forward-looking statements. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be 
material. Except as required by law, we undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, 
future events or otherwise.

This Annual Report on Form 10-K includes statistical and other industry and market data that we obtained from industry publications and research, 

surveys, and studies conducted by third parties as well as our own estimates of potential market opportunities. All of the market data used in this Annual 
Report on Form 10-K involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such data. Industry publications 
and third-party research, surveys, and studies generally indicate that their information has been obtained from sources believed to be reliable, although they 
do not guarantee the accuracy or completeness of such information. Our estimates of the potential market opportunities for our product candidates include 
several key assumptions based on our industry knowledge, industry publications, third-party research, and other surveys, which may be based on a small 
sample size and may fail to accurately reflect market opportunities. While we believe that our internal assumptions are reasonable, no independent source 
has verified such assumptions.

RISK FACTOR SUMMARY

Investing in our securities involves a high degree of risk. Below is a summary of material factors that make an investment in our securities 

speculative or risky. Importantly, this summary does not address all of the risks that we face. Additional discussion of the risks summarized in this risk 
factor summary, as well as other risks that we face, can be found under the heading “Risk Factors” in Item 1A of Part I of this Annual Report on Form 10-
K. 

Our business is subject to a number of risks of which you should be aware before making a decision to invest in our common stock. These risks 

include, among others, the following:

•

•

•

•

•

•

•

•

•

We have incurred net losses and anticipate that we may continue to incur net losses in the foreseeable future and therefore, may not be able to 
maintain profitability.

Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

We may require substantial additional funding to finance our operations. If we are unable to raise capital when needed, we could be forced to 
delay, reduce or terminate certain of our development programs or other operations.

We received an Emergency Use Authorization, or EUA, from the U.S. Food and Drug Administration, or FDA, for sotrovimab. If the FDA 
revokes or terminates our EUA for sotrovimab for the early treatment of COVID-19, the disease caused by the virus SARS-CoV-2, or the 
federally declared COVID-19 public health emergency ends, we will be required to stop commercial distribution of sotrovimab in the United 
States unless we can obtain FDA approval for this product and its currently authorized uses.

We are committing substantial financial resources and personnel and making substantial capital commitments with third parties in connection 
with sotrovimab as a therapy for COVID-19. Market demand and utilization of sotrovimab or any of our other COVID-19 product candidates 
may be adversely impacted by factors such as the development of monoclonal antibodies, or mAbs, of other third parties, the rollout of 
vaccines and oral antivirals, the emergence of new viral variants and the current challenges in the delivery and administration of mAbs to 
patients.

Our near-term success is dependent on the successful commercialization of sotrovimab for the early treatment of COVID-19, including our 
ability to enter into additional procurement contracts with government entities. If we are unable to successfully commercialize sotrovimab, 
our business, financial condition, results of operations and prospects may be adversely affected. In addition, sotrovimab may be rendered 
inferior or obsolete, even if it were to gain widespread market acceptance initially.

Our future success is substantially dependent on the successful clinical development, regulatory approval and commercialization of 
sotrovimab and product candidates in a timely manner. If we are not able to obtain required regulatory approvals, we will not be able to 
commercialize our product candidates and our ability to generate product revenue will be adversely affected.

Success in preclinical studies or earlier clinical trials may not be indicative of results in future clinical trials and we cannot assure you that 
any ongoing, planned or future clinical trials will lead to results sufficient for the necessary regulatory approvals and marketing 
authorizations.

Enrollment and retention of patients in clinical trials is an expensive and time-consuming process and could be delayed, made more difficult 
or rendered impossible by multiple factors outside our control.

We are a party to strategic collaboration and license agreements pursuant to which we are obligated to make substantial payments upon 
achievement of milestone events and, in certain cases, have relinquished important rights over the development and commercialization of 
certain current and future product candidates. We also intend to explore additional strategic collaborations, which may never materialize or 
may require that we relinquish rights to and control over the development and commercialization of our product candidates.

We intend to rely on third parties to produce clinical and commercial supplies of our product candidates.

If we are unable to obtain and maintain patent protection for our product candidates and technology, or if the scope of the patent protection 
obtained is not sufficiently broad or robust, our competitors could develop and commercialize products and technology similar or identical to 
ours, and our ability to successfully commercialize our product candidates and technology may be adversely affected.

We are highly dependent on our key personnel, and if we are not able to retain these members of our management team or recruit and retain 
additional management, clinical and scientific personnel, our business will be harmed.

Our business could be materially adversely affected by the effects of health pandemics or epidemics, including the current outbreak of 
COVID-19 pandemic and future outbreaks of the disease.

The market price of our common stock has been, and in the future, may be, volatile and fluctuate substantially, which could result in 
substantial losses for purchasers of our common stock.

If our information systems, or those maintained on our behalf, fail or suffer security breaches, such events could result in, without limitation, 
the following: a significant disruption of our product development programs; an inability to operate our business effectively; unauthorized 
access to or disclosure of the personal information we process; and other adverse effects on our business, financial condition, results of 
operations and prospects.

Overview 

Our mission is to create a world without infectious disease. 

PART I

We are a commercial-stage immunology company focused on combining immunologic insights with cutting-edge technologies to treat and prevent 

serious infectious diseases. Infectious diseases are among the leading causes of death worldwide and can cause trillions of dollars of direct and indirect 
economic burden each year – as evidenced by the coronavirus disease 2019, or COVID-19, pandemic. We believe that now is the time to apply the recent 
and remarkable advances in immunology to combat current and prepare for future infectious diseases. Our approach begins with identifying the limitations 
of the immune system in combating a particular pathogen, the vulnerabilities of that pathogen and the reasons why previous approaches have failed. We 
then bring to bear powerful technologies that we believe, individually or in combination, will lead to effective therapies. 

Our current pipeline consists of sotrovimab (previously VIR-7831; and where marketing authorization has been granted, marketed under the brand 
name Xevudy®) and other product candidates targeting COVID-19, hepatitis B virus, or HBV, influenza A virus, and human immunodeficiency virus, or 
HIV. We have assembled four technology platforms, focused on antibodies, T cells, innate immunity and small interfering ribonucleic acid, or siRNA, 
through internal development, collaborations and acquisitions. We have built an industry-leading team that has deep experience in immunology, infectious 
diseases, and product development and commercialization. Given the global impact of infectious diseases, we are committed to developing cost-effective 
treatments that can be delivered at scale. 

Our Pipeline 

Our current product and product candidates are summarized in the chart below: 

*Sotrovimab for early treatment by intravenous (IV) administration currently has marketing approval, emergency use authorization (EUA) or temporary authorization in >40 countries; 
for sotrovimab for early treatment by intramuscular (IM) administration, we and GSK (as defined below) recently filed an amendment request for an IM EUA with the FDA (as defined 
below).
**Vaccine designed to establish proof of concept in Phase 1 clinical trial to determine whether unique immune response observed in non-human primates can be replicated in humans; 
ultimately, any candidates we advance as a potential HIV vaccine will require modifications to VIR-1111 before further clinical development.

COVID-19: According to the John Hopkins Coronavirus Resource Center, as of February 23, 2022, there were almost 429.0 million recorded 
infections and almost 6.0 million recorded deaths worldwide from COVID-19. To date, the U.S. Food and Drug Administration, or FDA, has granted either 
Emergency Use Authorization, or EUA, or marketing approvals to multiple vaccines, drugs and/or antibodies to prevent or treat COVID-19. The ongoing 
efficacy of these medicines, however, particularly as the virus mutates while it infects more people and comes under increased immune pressure, is 
uncertain.

In response to the ongoing COVID-19 pandemic, we have moved rapidly, together with our collaborator Glaxo Wellcome UK Limited and 
GlaxoSmithKline Biologicals S.A. (individually and collectively referred to as GSK), to address this global health challenge. Our focus is on treating and 
preventing severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2 (the virus that causes COVID-19 illness), as well as potential future 
coronavirus outbreaks. To do so, we are developing differentiated monoclonal antibodies, or mAbs, like sotrovimab and VIR-7832, as well as vaccines and 
small molecules. 

Sotrovimab and VIR-7832 are SARS-CoV-2-neutralizing mAbs. Both sotrovimab and VIR-7832 are based on a parent antibody, S309, which was 

derived from samples previously gathered for research on pan-coronavirus-neutralizing mAbs. Preclinical and clinical data suggest that sotrovimab and 
VIR-7832 have the potential for ‘dual-action’, or the ability to block viral entry into healthy cells and an enhanced ability to clear infected cells. Both mAbs 
also bind to an epitope on SARS-CoV-2 that is shared with SARS-CoV-1 (the virus that causes SARS), indicating that the epitope is highly conserved, 
which may make it more difficult for viral resistance to develop. Both mAbs have also been designed to have an extended half-life and to have doses low 
enough to allow for intramuscular, or IM, in addition to intravenous, or IV, administration. In addition, VIR-7832 has been designed to potentially enhance 
virus-specific T cell function, which could also help treat and/or prevent COVID-19 infection.

Sotrovimab 

Early Treatment 

In August 2020, we initiated the lead-in phase of our Phase 2/3 trial COVID-19 Monoclonal antibody Efficacy Trial - Intent to Care Early, or 
COMET-ICE, for the treatment of adults at high risk of hospitalization or death from COVID-19 via IV administration. In October 2020, the trial continued 
into Phase 3 based on a positive evaluation of the safety and tolerability data. In March 2021, we announced an Independent Data Monitoring Committee 
recommended the Phase 3 COMET-ICE trial be stopped for enrollment due to evidence of profound efficacy. Later in March 2021, we submitted an EUA 
request to the FDA for 500 mg IV of sotrovimab based on the interim analysis of efficacy and safety data from COMET-ICE. 

In May 2021, the FDA granted an EUA to sotrovimab for the early treatment of mild to moderate COVID-19 in adults and pediatric patients (12 

years of age and older weighing at least 40 kg) with positive results of direct SARS-CoV-2 viral testing, and at high risk for progression to severe COVID-
19, including hospitalization or death. We also received a positive scientific opinion from the Committee for Human Medicinal Products in the European 
Union, or EU, for sotrovimab in May 2021. In June 2021, we announced confirmatory full results for the Phase 3 COMET-ICE trial, which resulted in an 
adjusted relative risk reduction of 79% (p<0.001) in all-cause hospitalization for more than 24 hours or death due to any cause by Day 29 compared to 
placebo, meeting the primary endpoint of the trial. In December 2021, the European Commission granted marketing authorization to Xevudy® 
(sotrovimab) in the EU for the treatment of adults and adolescents at increased risk of progressing to severe COVID-19. 

During and following the fourth quarter of 2021, we announced preclinical data generated through pseudovirus testing demonstrating that 

sotrovimab retains neutralizing activity against the highly divergent Omicron variant (B.1.1.529). In February 2022, we published pseudovirus data 
demonstrating a 16-fold shift in neutralization activity against the Omicron BA.2 subvariant. Our BA.2 results were derived from 10 independent 
experiments that were conducted using an optimized pseudovirus assay. This is the same assay that was used to generate data for previous variants. These 
data have been shared with regulatory agencies around the world. Initial feedback from the FDA question our conclusion that the 500 mg IV dose of 
sotrovimab retains activity against the BA.2 Omicron subvariant based on our current modeling assumptions, and the FDA has asked for additional data to 
support our position. The FDA also requested safety data for higher doses. Both have been provided to the FDA and we are awaiting further 
correspondence.

5

 
The Health Care Provider Fact Sheet was recently updated to show that sotrovimab’s neutralization activity was reduced an average fold change in 
EC50 value of 16-fold against the SARS-CoV-2 Omicron B.1.1.529/BA.2 spike variant compared to wild-type. The Fact Sheet also noted that the clinical 
relevance of the 16-fold reduction in sotrovimab activity against the SARS-CoV-2 Omicron B.1.1.529/BA.2 variant is unknown. As of February 28, 2022, 
the FDA noted on its EUA website that sotrovimab is currently authorized in all U.S. regions until further notice by the FDA.

In an effort to facilitate broader patient access through IM administration, we also conducted two IM trials. In February 2021, we initiated COMET-

Patient SafEty, TolerAbility, PharmacoKinetics, or COMET-PEAK, a Phase 2 trial, evaluating an IM formulation of sotrovimab in low-risk adults with 
mild to moderate COVID-19. In June 2021, we initiated COMET-Treatment of Acute COVID-19 with Intramuscular monocLonal antibody, or COMET-
TAIL, a Phase 3 trial in adults at high risk of hospitalization or death. In November 2021, we announced that the COMET-TAIL Phase 3 trial’s primary 
endpoint had been met, with headline data demonstrating that IM-administered sotrovimab was non-inferior to IV administration for high-risk populations. 
In January 2022, we filed an amendment to sotrovimab’s EUA to include IM administration. 

We and GSK plan to submit a Biologics License Application, or BLA, for sotrovimab to the FDA in the second half of 2022.  

We and GSK continue to work actively with governments and payors around the world to make sotrovimab available to patients in need. 
Sotrovimab has been granted EUA, temporary authorization or marketing approval (under the brand name Xevudy®) in more than 40 countries, and we 
have received binding agreements for the sale of approximately 1.7 million doses of sotrovimab worldwide.

Prophylaxis

We are supporting multiple clinical trials evaluating whether sotrovimab, administered as prophylaxis, can help prevent symptomatic COVID-19 in 
uninfected immunocompromised adults. Two Phase 3 trials are expected to start in the second quarter of 2022. One is a platform trial and one is a company 
sponsored trial, COVID-19 Monoclonal antibody Efficacy Trial – Stop Transmission of Acute SARS-COV-2, or COMET-STAR. The primary endpoint for 
both trials is incidence of symptomatic PCR-confirmed COVID-19. The analysis of the primary endpoint of COMET-STAR will be event driven, and could 
be as early as the second half of 2022.

Hospitalized treatment

In December 2020, we initiated Therapeutics for Inpatients with COVID-19, or TICO, a Phase 3 trial of sotrovimab for the treatment of hospitalized 
adults with COVID-19 as part of a sub-trial of the National Institutes of Health’s, or NIH, Accelerating COVID-19 Therapeutic Interventions and Vaccines, 
or ACTIV, Program, specifically ACTIV-3. In March 2021, we announced that the sotrovimab arm of the NIH’s ACTIV-3 clinical trial met initial pre-
specified criteria, and no safety signals were reported. Based on sensitivity analyses of the available data, the independent Data and Safety Monitoring 
Board recommended the sotrovimab arm be closed to enrollment. 

In December 2021, sotrovimab entered the Randomized Evaluation of COVID-19 Therapy, or RECOVERY, trial, a Phase 3 trial in the U.K. 
evaluating standard of care alone versus usual standard of care plus a single dose of sotrovimab given IV. Initial data is expected in the second half of 2022.

VIR-7832. In April 2021, we initiated a Phase 1b/2a trial of VIR-7832 for the potential treatment of adults with mild to moderate COVID-19 as part 

of the U.K.'s National Health Service, or NHS, supported AGILE initiative. The dose-escalation Phase 1b part of the trial evaluates the safety and 
tolerability of single ascending doses of VIR-7832 for the treatment of mild to moderate COVID-19. The Phase 2a portion evaluates the safety and 
virologic activity of VIR-7832, as well as T cell responses to SARS-CoV-2 of VIR-7832 and sotrovimab. The Phase 1b trial is ongoing and no safety 
signals have been reported to date for the 50 mg, 150 mg, and 500 mg dose cohorts. The first patient in the Phase 2a portion of the trial was dosed in 
February 2022. Additional data are expected in the first half of 2022. In July 2021, VIR-7832's investigational new drug, or IND, application was cleared 
by the FDA. 

In connection with the advancement of our COVID-19 mAbs, we and GSK have established a strategic manufacturing network, which will enable 

the manufacture of approximately two million doses of sotrovimab in the first half of 2022, and additional doses in the second half of 2022. We are actively 
working to expand our capacity to increase supply through 2022 so that we can continue to serve more patients. See the section titled “Manufacturing” for a 
summary of our manufacturing 

6

 
activities and a description of the agreements with WuXi Biologics (Hong Kong) Limited, or WuXi Biologics, and Samsung Biologics Co., Ltd., or 
Samsung.  

In addition to sotrovimab and VIR-7832, we are preparing for future pandemics with coronavirus mAbs that have the potential to be even broader 
and more potent than sotrovimab, pan-coronavirus vaccines designed with the aim to be variant-proof (initial pre-clinical proof of concept achieved), and 
small molecules that have the potential to treat multiple respiratory diseases like COVID-19 and influenza (initial pre-clinical proof of concept achieved).

HBV: According to the Hepatitis B Foundation, approximately 300 million people globally are chronically infected with HBV and approximately 
900,000 of them die from HBV-associated complications each year. There is a significant unmet medical need for more effective therapies that lead to life-
long control of the virus after a finite duration of therapy, which is the definition of a functional cure. For a registrational trial to demonstrate a functional 
cure, the formal endpoint accepted by the FDA is undetectable hepatitis B virus surface antigen, or HBsAg, defined as less than 0.05 international units per 
milliliter, or IU/ml, as well as HBV DNA less than the lower limit of quantification, in the blood six months after the end of therapy. Currently, a year-long 
course of pegylated interferon-alpha, or PEG-IFN-α, is the best available curative therapy. It has a low functional cure rate of approximately three to seven 
percent. Alternatively, suppressive therapy with nucleotide/nucleoside reverse transcriptase inhibitors, or NRTIs, is commonly used, but patients often 
require a lifetime of therapy. 

We are developing VIR-2218 and VIR-3434 for the functional cure of HBV. Each of these product candidates has the potential to stimulate an 

effective immune response and also has direct antiviral activity against HBV. We believe that a functional cure for HBV will require an effective immune 
response in addition to antiviral activity based on the observation that severe immunosuppression can reactivate HBV disease. While monotherapy with 
VIR-2218 and VIR-3434 may provide a functional cure in some patients, we believe combination therapy will be necessary for a functional cure in many 
patients. 

VIR-2218 is an investigational subcutaneously administered HBV-targeting siRNA. By targeting a conserved region of the HBV genome, it is 

designed to inhibit the production of all HBV proteins: X, polymerase, S, and core. Suppression of HBV proteins, particularly HBsAg, is hypothesized to 
remove the inhibition of T cell and B cell activity directed against HBV, allowing VIR-2218 to potentially result in a functional cure. VIR-2218 was the 
first siRNA in the clinic to include Alnylam Pharmaceuticals, Inc.’s, or Alnylam, Enhanced Stabilization Chemistry Plus, or ESC+, technology, which has 
the potential to enhance the therapeutic index. 

In June 2021, we announced clinical data from our Phase 2 trial of VIR-2218 alone and in combination with PEG-IFN-α. First, with VIR-2218 as 
monotherapy, the trial demonstrated a strong safety profile and a substantial, durable and dose dependent reduction of HBsAg through 48 weeks. Second, 
evaluating VIR-2218 alone and in combination with PEG-IFN-α for 12 weeks, more rapid and substantial declines in HBsAg compared to VIR-2218 alone 
were observed.

In November 2021, we announced additional data evaluating VIR-2218 in combination with PEG-IFN-α for 24 weeks. New findings demonstrated 
that concurrent initiation of VIR-2218 and PEG-IFN-α therapy resulted in earlier and more substantial HBsAg reductions compared to VIR-2218 alone or 
with PEG-IFN-α following a VIR-2218 lead-in. Three participants achieved HBsAg loss below the lower limit of quantification by Week 24; two of three 
achieved anti-HBs seroconversion. Additional data are expected in the first half of 2022. 

VIR-2218 is also being evaluated in additional clinical trials with collaborators. Brii Biosciences Offshore Limited, or Brii Bio, continues to lead the 

Phase 2 trial of VIR-2218 in combination with BRII-179, an investigational T cell vaccine, for the treatment of chronic HBV infection. Initial data are 
expected in the second half of 2022. In December 2021, we and Gilead Sciences, Inc., or Gilead, initiated a Phase 2 clinical trial of VIR-2218 in 
combination with GS-9688 (selgantolimod), Gilead's investigational TLR-8 agonist, and nivolumab, an approved PD-1 inhibitor, in both nucleos(t)ide, or 
NUC- suppressed patients and viremic patients. Patients with HBV treatment experience also may receive tenofovir alafenamide fumarate, or TAF. 

VIR-3434 is an investigational subcutaneously administered HBV-neutralizing mAb. By targeting a conserved region of HBsAg, it is designed to 

block entry of all 10 genotypes of HBV into liver cells called hepatocytes and reduce the level of virions and subviral particles in the blood. VIR-3434, 
which incorporates Xencor, Inc.'s, or Xencor, Xtend and other Fc technologies, has been engineered to potentially function as a T cell vaccine against HBV 
in infected patients, as well as to have an extended half-life. These modifications are intended to enhance its potential to result in an HBV functional cure. 

Building on the data previously disclosed in January and June 2021, in November 2021 we announced that a single dose of six mg, 18 mg, or 75 mg 

of VIR-3434 resulted in rapid HBsAg reductions in most participants within approximately 

7

 
one week post-dose, and the largest and most sustained reductions in HBsAg were observed in the 75 mg cohort. Additional data are expected in the first 
half of 2022. 

In July 2021, we initiated the Phase 2 Monoclonal Antibody siRNA Combination against Hepatitis B, or MARCH, trial to evaluate the combination 

of VIR-2218 and VIR-3434 as a functional cure regimen for chronic HBV infection. Initial data are expected in the first half of 2022. As some of our 
clinical trial sites are in Ukraine and Moldova, we are monitoring the situation to determine any impact resulting from the current conflict in this region. 

Influenza: According to the World Health Organization, or WHO, on average, each year the influenza virus is estimated to infect 1 billion people 
and to result in 290,000 to 650,000 deaths globally. According to the Centers for Disease Control and Prevention, or CDC, in the 2018-2019 flu season, 
despite the availability of the flu vaccine, approximately 36 million people were diagnosed with influenza, 500,000 people were hospitalized, and 34,000 
people died from influenza in the United States alone. Influenza vaccines have historically had limited success, with an average efficacy of 40% overall, 
across all populations. This limited efficacy results from incomplete coverage against seasonal strains and the lack of an effective immune response in 
many individuals after receiving the vaccine. 

We are developing VIR-2482 as a universal prophylactic for influenza A and have designed it to overcome both limitations of flu vaccines, which 

we believe will lead to meaningfully higher levels of protection against seasonal and pandemic strains of influenza A. We anticipate that the initial 
registration population for VIR-2482 will include individuals at high risk of influenza A complications, such as the elderly with chronic lung disease or 
congestive heart failure. 

In May 2021, we signed a definitive collaboration agreement, or the 2021 GSK Agreement, with GSK to expand our existing collaboration to 

include the research and development of new therapies for influenza and other respiratory viruses. See the section titled “Our Collaboration, License and 
Grant Agreements—Collaboration Agreements with GSK” for a description of the 2021 GSK Agreement.

VIR-2482 is an investigational IM administered influenza A-neutralizing mAb. In vitro, VIR-2482 has been shown to neutralize all major strains of 

influenza A that have arisen since the 1918 Spanish flu pandemic and is designed as a universal prophylactic for influenza A. We believe that VIR-2482 
has the potential to provide superior protection to flu vaccines and be able to be used year after year because it has broad strain coverage as opposed to the 
limited strain coverage generated by vaccines. We also believe that it provides passive immunity rather than relying on a person to generate active 
immunity via a functional immune response, an ability that is known to decline with age. VIR-2482 has been engineered to extend its half-life so that a 
single IM dose has the potential to last the entire flu season, which is typically five to six months long. VIR-2482 is estimated to have a half-life of 58 days 
based on preliminary data. 

In August 2019, we initiated dosing in the Phase 1/2 clinical trial for VIR-2482. VIR-2482 has been well-tolerated in the approximately 100 healthy 

volunteers dosed in Phase 1. Anticipating an increase in the incidence of influenza in the Northern Hemisphere this coming winter, we expect to initiate a 
Phase 2 trial in the second half of 2022. 

HIV: According to the Joint United Nations Programme on HIV/AIDS, or UNAIDS, each year there are approximately 1.5 million new cases of 

HIV and approximately 700,000 HIV-related deaths globally. Current prevention approaches such as behavioral modification and pharmacological 
intervention have had only a modest effect on HIV transmission globally, leaving a high unmet medical need for a safe and effective vaccine for the billions 
of individuals who are or may become sexually active. 

We are developing VIR-1111 as a proof of concept HIV vaccine designed to elicit a type of immune response that is different from other vaccines. 

We anticipate the initial registration population for our eventual HIV vaccine will be individuals at high risk of contracting HIV.

VIR-1111 is an investigational subcutaneously administered HIV T cell vaccine based on human cytomegalovirus, or HCMV. VIR-1111 has been 

designed to elicit T cells that recognize HIV epitopes that are different from those recognized by prior HIV vaccines and to stimulate a different and 
specific type of T cell immune response to HIV, known as an HLA-E restricted immune response. An HLA-E restricted immune response has been shown 
to be associated with protection of non-human primates, or NHPs, from simian immunodeficiency virus, or SIV, the NHP equivalent of HIV. VIR-1111 is a 
vaccine designed solely to establish proof of concept in a Phase 1 clinical trial to determine whether the unique immune response observed in NHPs can be 
replicated in humans. 

In December 2020, we initiated a Phase 1 trial of VIR-1111. No safety signals have been reported to date and we expect to have additional clinical 

data in the first half of 2022.

Our Technology Platforms 

Our four current technology platforms are designed to stimulate and enhance the immune system by exploiting critical observations of natural 
immune processes. We are using our platforms to advance sotrovimab and other current product candidates and generate additional product candidates for 
multiple indications. 

Antibody Platform: We have established a robust method for capitalizing on unusually successful immune responses naturally occurring in people 
who are protected from, or have recovered from, infectious diseases. We identify rare antibodies from survivors that have the potential to treat and prevent 
rapidly evolving and/or previously untreatable pathogens via direct pathogen neutralization and immune system stimulation. The fully-human antibodies 
that we discover may also be modified to enhance their therapeutic potential. We have applied these methods to identify mAbs for a range of pathogens 
including SARS-CoV-2, HBV, influenza A and influenza B virus, Ebola, respiratory syncytial virus, or RSV, malaria, clostridium difficile, Staphylococcus 
aureus, Klebsiella pneumoniae, and Acinetobacter spp. Examples of the power of this platform are Xevudy® (sotrovimab, formerly known as VIR-7831), 
our anti-SARS-CoV-2 mAb, and Ebanga (ansuvimab-zykl, formerly known as mAb114), the anti-Ebola virus mAb identified by our scientists in 
collaboration with the NIH and others and marketed by Ridgeback Biotherapeutics LP. 

T Cell Platform: We are exploiting the unique immunology of HCMV, a commonly occurring virus in humans, as a vaccine vector to potentially 
treat and prevent infection by pathogens refractory to current vaccine technologies. This approach is based on fundamental observations made in NHPs, 
with rhesus cytomegalovirus, or RhCMV. HCMV is the most potent known inducer of T cell responses of any human virus and may induce potent and 
long-lasting T cell responses to a broader range of epitopes than observed for other viral vaccines. In addition, we can make proprietary modifications in 
the HCMV genome that we expect will elicit different types of pathogen-appropriate T cell responses. We term this approach “immune programming.” We 
believe that this platform may also have applicability beyond infectious diseases, to areas such as cancer. 

Innate Immunity Platform: Moving beyond more traditional approaches that are used to evoke adaptive immunity or that directly target pathogens, 

where the development of resistance can occur, we plan to target host proteins as a means of creating host-directed therapies with high barriers to 
resistance. We believe that by leveraging the power of innate immunity, we can create medicines that break the “one-drug-for-one-bug” paradigm by 
producing “one-drug-for-multiple-bugs.” For example, we believe this platform can create a single product for respiratory viruses, such as SARS-CoV-2 
and influenza. This is enabled using clustered regularly interspaced short palindromic repeats, or CRISPR, -based genomics, computational biology and 
machine learning to identify key host factors necessary for each pathogen’s survival and the protective effects of the innate immune system. We then 
identify product candidates that may be able to safely target host proteins to block pathogen replication or induce innate immunity to control infection. We 
believe that this platform may also have applicability beyond infectious diseases.

siRNA Platform: We are harnessing the power of siRNA to inhibit pathogen replication, eliminate key host factors necessary for pathogen survival 

and remove microbial immune countermeasures. Our collaboration with Alnylam includes VIR-2218 for HBV and up to four additional programs for 
infectious diseases. This platform can leverage Alnylam’s proprietary N-acetylgalactosamine, or GalNAc, delivery technology, for product candidates 
targeting the liver, allowing for subcutaneous administration and extended tissue half-life, as well as ESC+ technology to enhance stability and minimize 
off-target activity, which potentially can result in an increased therapeutic index.

Our Strategy 

We are a commercial-stage immunology company focused on combining immunologic insights with cutting-edge technologies to treat and prevent 

serious infectious diseases. The core elements of our business strategy include: 

•

•

•

•

•

•

Maximizing the impact of sotrovimab. Sotrovimab has been granted EUA, temporary authorization or marketing approval in more than 40 
countries. We and GSK will continue to work actively with governments and payors around the world to make sotrovimab available to 
patients in need.

Rapidly advancing our pipeline. Currently underway are two Phase 3 clinical trials, five Phase 2 clinical trials, and four Phase 1 clinical 
trials across four distinct therapeutic areas. We anticipate moving additional preclinical candidates into the clinic and initiating additional 
later-stage combination trials where applicable in the next 12-18 months. 

Expanding our pipeline using our current technology platforms. We are leveraging our four current technology platforms to discover and 
develop novel product candidates for COVID-19, HBV, influenza A virus, HIV and tuberculosis, or TB, as well as additional viral, bacterial, 
fungal and parasitic infections, and potentially cancers. 

Acquiring or accessing new technology platforms and assets. We continually evaluate external technology platforms and assets that may 
help us develop therapies to treat and prevent serious infectious diseases. 

Scaling our capabilities. We are investing in our people, processes and systems across all functions of our company to ensure that we are 
able to take full advantage of our multiple product candidates and multiple technology platforms. 

Enabling global access to our future medicines. We have established relationships with organizations seeking to make a global impact like 
the Bill & Melinda Gates Foundation, the NIH, and the NHS to further enable and facilitate access to our future medicines and to support our 
clinical development efforts. We will continue to pursue additional relationships like these moving forward.

Pipeline

Our current pipeline consists of a product and product candidates that address unmet needs caused by COVID-19, HBV, influenza A virus, and HIV. 

*Sotrovimab for early treatment by IV currently has marketing approval, EUA or temporary authorization in >40 countries; for sotrovimab for early treatment by IM, we and GSK 
recently filed an amendment request for an IM EUA with the FDA.
**Vaccine designed to establish proof of concept in Phase 1 clinical trial to determine whether unique immune response observed in non-human primates can be replicated in humans; 
ultimately, any candidates we advance as a potential HIV vaccine will require modifications to VIR-1111 before further clinical development. 

Treatment and Prophylaxis for COVID-19 

Summary 

In response to the ongoing COVID-19 pandemic, we have moved rapidly, together with our collaborator GSK, to address this global health 
challenge. Our focus is on treating and preventing COVID-19, as well as potential future coronavirus outbreaks. To do so, we are developing differentiated 
mAbs like sotrovimab and VIR-7832, as well as vaccines and small molecules.

We are developing sotrovimab and VIR-7832 for the treatment and prophylaxis of COVID-19. Both sotrovimab and VIR-7832 are based on a parent 

antibody, S309, which was derived from samples previously gathered for research on pan-coronavirus-neutralizing mAbs. Preclinical and clinical data 
suggest that sotrovimab and VIR-7832 have the potential for ‘dual-action’, or the ability to block viral entry into healthy cells and an enhanced ability to 
clear infected cells. Both mAbs also bind to an epitope on SARS-CoV-2 that is shared with SARS-CoV-1 (the virus that causes SARS), indicating that the 
epitope is highly conserved, which may make it more difficult for viral resistance to develop. Both mAbs have also been designed to have an extended half-
life and to have doses low enough to allow for IM and IV administration. In addition, VIR-7832 has been designed to potentially enhance virus-specific T 
cell function, which could also help treat and/or prevent COVID-19 infection.

During and following the fourth quarter of 2021, we announced preclinical data generated through pseudovirus testing demonstrating that 

sotrovimab retains neutralizing activity against the highly divergent Omicron variant (B.1.1.529). In February 2022, we published pseudovirus data 
demonstrating a 16-fold shift in neutralization activity against the Omicron BA.2 subvariant. Our BA.2 results were derived from 10 independent 
experiments that were conducted using an optimized pseudovirus assay. This is the same assay that was used to generate data for previous variants. These 
data have been shared with regulatory agencies around the world. Initial feedback from the FDA question our conclusion that the 500 mg IV dose of 
sotrovimab retains activity against the BA.2 Omicron subvariant based on our current modeling assumptions, and the FDA has asked for additional data to 
support our position. The FDA also requested safety data for higher doses. Both have been provided to the FDA and we are awaiting further 
correspondence.

11

 
 
 
The Health Care Provider Fact Sheet was recently updated to show that sotrovimab’s neutralization activity was reduced an average fold change in 
EC50 value of 16-fold against the SARS-CoV-2 Omicron B.1.1.529/BA.2 spike variant compared to wild-type. The Fact Sheet also noted that the clinical 
relevance of the 16-fold reduction in sotrovimab activity against the SARS-CoV-2 Omicron B.1.1.529/BA.2 variant is unknown. As of February 28, 2022, 
the FDA noted on its EUA website that sotrovimab is currently authorized in all U.S. regions until further notice by the FDA.   

To date, sotrovimab has been granted EUA, temporary authorization or marketing approval (under the brand name Xevudy®) for the early treatment 

of COVID-19 in more than 40 countries, and we have received binding agreements for the sale of approximately 1.7 million doses worldwide. We and 
GSK continue to work actively with governments and payors around the world to make sotrovimab available to patients in need. We and GSK plan to 
submit a BLA for sotrovimab to the FDA in the second half of 2022. 

We are also evaluating the use of sotrovimab in two additional indications: 1) to determine if sotrovimab can prevent symptomatic COVID-19 

infection in uninfected immunocompromised adults or those who have a history of severe adverse reactions to COVID-19 vaccines, and 2) to evaluate if 
sotrovimab treatment can improve clinical outcomes in patients hospitalized with COVID-19. 

We and GSK have established a strategic manufacturing network, which will enable the manufacture of approximately two million doses of 

sotrovimab in the first half of 2022, and additional doses in the second half of 2022. We are actively working to expand our capacity to increase supply 
through 2022 so that we can continue to serve more patients. See the section titled “Manufacturing” for a summary of our manufacturing activities and a 
description of the agreements with WuXi Biologics and Samsung. 

VIR-7832, an anti-SARS-CoV-2 mAb, is currently in a Phase 1b/2a trial for the potential treatment of adults with mild to moderate COVID-19 as 
part of the U.K.'s NHS-supported AGILE initiative. The Phase 1b trial is ongoing and no safety signals have been reported to date for the 50 mg, 150 mg, 
and 500 mg dose cohorts. The first patient in the Phase 2a portion of the trial was dosed in February 2022. Additional data are expected in the first half of 
2022. In July 2021, VIR-7832’s IND application was cleared by the FDA. 

In addition to sotrovimab and VIR-7832, we are preparing for future pandemics with coronavirus mAbs that have the potential to be even broader 
and more potent than sotrovimab, pan-coronavirus vaccines designed with the aim to be variant-proof (initial pre-clinical proof of concept achieved), and 
small molecules that treat multiple respiratory diseases like COVID-19 and influenza (initial pre-clinical proof of concept achieved).

However, there are no assurances that we will secure additional supply commitments from governments. In addition, COVID-19 treatment standards 

are susceptible to rapid changes in epidemiology and the emergence of new variants, thus, sotrovimab may be rendered inferior or obsolete in the future. 
The FDA may, under certain circumstances, revise or revoke an EUA. If our EUA is terminated or revoked, sotrovimab will no longer be available in the 
United States unless and until we have obtained FDA approval of a BLA for the product. 

Disease Overview and Limitations of Current Standard of Care

According to the John Hopkins Coronavirus Resource Center, as of February 23, 2022, there were almost 429.0 million recorded infections and 

almost 6.0 million recorded deaths worldwide from COVID-19. To date, the FDA has granted either EUAs or marketing approvals to multiple vaccines, 
drugs and/or antibodies to prevent or treat COVID-19. 

For prophylaxis, despite the high efficacy of the COVID-19 vaccines, there are still populations in whom vaccine immunogenicity is suboptimal, 

such as the elderly with comorbidities, immunocompromised persons, or those who may not want or be able to tolerate vaccines. 

For early treatment, both mAbs and small molecules have shown strong efficacy data and have pros and cons around convenience and compliance. 
For example, for some patients and their physicians, IM or IV mAbs may be preferred to small molecules due to administration in a single treatment visit 
(“one and done”), concerns about compliance with small molecules (multiple pills, multiple times per day, over multiple days), and concerns about oral 
treatment initiation requirements. 

12

 
For hospitalized patients, there is still significant unmet need. Preliminary data suggest that COVID-19 mAbs may have a role in improving clinical 

outcomes such as decreasing intensive care unit stays and/or mortality in hospitalized patients who have severe or critical COVID-19. 

Importantly, the ongoing durability of current vaccines, small molecules, and mAbs in the setting of the continued emergence of variants like 

Omicron is uncertain. 

Sotrovimab for COVID-19

Molecular Characteristics. Sotrovimab is an investigational fully human IgG1 neutralizing anti-SARS-CoV-2 monoclonal antibody that has Fc 

modifications that are designed to improve bioavailability in the respiratory mucosa and increase half-life, and incorporates Xencor’s XtendTM technology. 
Sotrovimab binds with high affinity to the receptor binding domain of the SARS-CoV-2 spike protein. It is designed to have dual-actions of neutralizing the 
virus by blocking viral entry into healthy cells, while also enhancing the ability to clear infected cells. Sotrovimab potently neutralizes live SARS-CoV-2 in 
vitro and in vivo, and binds to a highly conserved epitope that is shared with SARS-CoV-1, thus potentially leading to a wide breadth of sarbecovirus 
coverage and a higher barrier to resistance. Sotrovimab’s dose may allow for both IM and IV administration.

Phase 2/3 Trials of Sotrovimab.

COMET-ICE: Sotrovimab was evaluated as a treatment in adults with mild to moderate COVID-19 at high risk of hospitalization or death. This trial 

was a Phase 2/3, randomized, double-blind, multi-center, placebo-controlled trial investigating IV infusion of 500 mg of sotrovimab in adults with mild to 
moderate COVID-19 at high-risk of progression to severe disease, who were not hospitalized and did not require oxygen. The trial included a lead-in phase 
to evaluate the safety and tolerability of sotrovimab, followed by an expansion phase with 1:1 randomization of sotrovimab and placebo. The final 
COMET-ICE trial results in the full trial population of 1,057 participants demonstrated an adjusted relative risk reduction of 79% (p<0.001) in 
hospitalization for more than 24 hours or death due to any cause by Day 29 compared to placebo, meeting the primary endpoint of the trial. 

COMET-TAIL: Sotrovimab was evaluated in a Phase 3, multi-center, randomized, open-label, non-inferiority trial of IM versus IV administration of 

sotrovimab for the early treatment of mild-to-moderate COVID-19 in high-risk non-hospitalized adult and pediatric patients (12 years of age and older). 
The trial included three arms: 500 mg of sotrovimab given IV, and two IM arms, consisting of 500 mg and a low dose of 250 mg. The trial enrolled a total 
of 983 patients up to seven days after onset of symptoms. The trial’s primary endpoint was met, and headline data demonstrated that IM-administered 
sotrovimab was non-inferior to IV administration for high-risk populations. In February 2022, topline data were presented at the Conference on 
Retroviruses and Opportunistic Infections (CROI 2022), and we plan to submit the full COMET-TAIL data set to a peer-reviewed journal for publication in 
the first half of 2022.

COMET-PEAK: Sotrovimab was evaluated in a Phase 2, multi-center, randomized, double-blind, two-part, parallel group trial designed to compare 

1) the safety, tolerability and pharmacokinetics of second-generation sotrovimab manufactured material to first-generation sotrovimab manufactured 
material intravenously, and 2) the viral kinetics and safety of IV administration compared to IM administration of sotrovimab in low-risk adults with mild 
to moderate COVID-19. Data available to date from open label Part B of the trial (500 mg IV vs. 500 mg IM) demonstrated equivalence on the virological 
response between the IM and IV arms, while also showing an acceptable tolerability profile for IM with only 10/82 participants (12%) reporting any 
injection site reaction, all of which were low grade (Grade 1). 

Based on the data from the COMET-TAIL and COMET-PEAK trials, in January 2022 we submitted an application to the FDA requesting an 

amendment to the EUA for sotrovimab to include IM administration. 

RECOVERY: Sotrovimab is being evaluated in a randomized, controlled, open-label, platform trial assessing several possible treatments in patients 
hospitalized with COVID-19 in the U.K. Trial participants who are hospitalized with COVID-19 are eligible for random assignment in a 1:1 ratio to usual 
standard of care alone versus usual standard of care plus a single dose of sotrovimab given IV. Initial data are expected in the second half of 2022.

COMET-STAR: This is a planned Phase 3, multicenter, randomized, double-blind, placebo-controlled trial to evaluate IV sotrovimab as prophylaxis 
for COVID-19. The primary endpoint of this trial is incidence of symptomatic PCR-confirmed COVID-19. Enrollment is planned to initiate in the second 
quarter of 2022. The analysis of the primary endpoint of COMET-STAR will be event driven, and could be as early as the second half of 2022.

VIR-7832 for COVID-19

Molecular Characteristics. VIR-7832 is identical to sotrovimab, except that VIR-7832 contains additional modifications in the Fc domain that are 
designed to further enhance its effector function, such as antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis, abrogate 
C1q binding, as well as elicit enhanced T cell and antibody responses. VIR-7832 incorporates Xencor’s XtendTM and other Fc technologies. These 
additional modifications may increase potency and induce a “vaccinal” effect (the induction of antigen-specific T cell responses) in patients with COVID-
19.

Phase 1b/2a Trial of VIR-7832. VIR-7832 is being evaluated as part of the U.K.-based, NHS-supported AGILE initiative. The Phase 1b portion of 
the trial is a double-blinded, randomized, first-in-human dose-escalation trial of VIR-7832 in which adults with mild to moderate COVID-19 infection are 
randomized to VIR-7832 or placebo in a 3:1 ratio. The primary objective of Phase 1b is to determine the safety and tolerability of single ascending doses of 
VIR-7832 for the treatment of mild to moderate COVID-19. No concerning safety signals have been reported for the 50 mg, 150 mg and 500 mg dose 
cohorts to date. The Phase 2a portion of the trial is evaluating 500 mg of VIR-7832, 500 mg of sotrovimab and placebo, randomized in a 2:2:1 ratio in 
participants with mild to moderate COVID-19. The primary objective of the double-blinded, placebo-controlled, randomized Phase 2a is to investigate the 
safety and virologic activity of VIR-7832 compared to sotrovimab in patients with mild to moderate COVID-19 infection. Immunologic parameters, such 
as T-cell responses to SARS-CoV-2, will also be examined. Additional data are expected in the first half of 2022.   

Functional Cure for HBV 

Summary 

We are developing VIR-2218 and VIR-3434 for the functional cure of HBV. Each of these product candidates has the potential to stimulate an 

effective immune response and also has direct antiviral activity against HBV. We believe that a functional cure for HBV will require an effective immune 
response, in addition to antiviral activity, based on the observation that severe immunosuppression can reactivate HBV disease. While monotherapy with 
VIR-2218 and VIR-3434 may provide a functional cure in some patients, we believe combination therapy will be necessary for a functional cure in many 
patients. 

VIR-2218, an HBV-targeting siRNA, is currently in a Phase 2 clinical trial. In Parts A to C of the trial, 37 healthy volunteers and 24 patients with 
chronic HBV on NRTIs received VIR-2218. The data suggest that VIR-2218 is generally well-tolerated in healthy volunteers given as a single dose up to 
900 mg and in patients given as two doses of 20 mg, 50 mg, 100 mg or 200 mg each dose. The data also demonstrate substantial, durable, dose dependent 
reductions in HBsAg in patients at doses ranging from 20 mg to 200 mg, which are durable at the higher doses through 48 weeks. Parts D and F evaluating 
six doses of 200 mg of VIR-2218 with PEG-IFN-α showed rapid and substantial declines in HBsAg levels after 24 weeks of treatment compared to VIR-
2218 alone. VIR-2218 is also being explored in additional clinical trials with collaborators. Brii Bio continues to lead the Phase 2 trial of VIR-2218 in 
combination with BRII-179, an investigational T cell vaccine, for the treatment of chronic HBV infection. Initial data are expected in the second half of 
2022. In December 2021, we and Gilead initiated a Phase 2 clinical trial of VIR-2218 in combination with GS-9688 (selgantolimod), Gilead's 
investigational TLR-8 agonist, and nivolumab, an approved PD-1 inhibitor, in both NUC-suppressed patients and viremic patients. Patients with HBV 
treatment experience also may receive TAF.

VIR-3434, an HBV-neutralizing mAb, is currently in a Phase 1 clinical trial. Two analyses from our ongoing Phase 1 trial showed no safety signals 
in healthy volunteers dosed with up to 3,000 mg, and a rapid reduction in HBsAg levels one week after subcutaneous administration of a single dose of six 
to 75 mg of VIR-3434 to virally suppressed patients with chronic HBV infection. The largest and most sustained reductions in HBsAg were observed in the 
75 mg cohort. In July 2021, we initiated the Phase 2 MARCH trial to evaluate the combination of VIR-2218 and VIR-3434 as a functional cure regimen for 
chronic HBV infection. Initial data are expected in the first half of 2022. As some of our clinical trial sites are in Ukraine and Moldova, we are monitoring 
the situation to determine any impact resulting from the current conflict in this region. 

Disease Overview and Limitations of Current Standard of Care 

According to the Hepatitis B Foundation, approximately 300 million people globally are chronically infected with HBV. In the United States, up to 

two million people are chronically infected with HBV. Chronic HBV can lead to many serious complications, including liver scarring, liver failure and liver 
cancer. Globally, approximately 900,000 people die each year from HBV-associated complications. 

14

 
The most commonly used therapy for chronic HBV is life-long suppressive therapy with NRTIs, like tenofovir or entecavir. Of the hundreds of 

millions of people with chronic HBV worldwide, only an estimated two percent of patients are currently taking this suppressive therapy. NRTIs prevent 
HBV ribonucleic acid, or RNA, from being transcribed into HBV deoxyribonucleic acid, or DNA, which is a process known as reverse transcription. 
NRTIs therefore have little to no direct impact on covalently closed circular DNA, or cccDNA, the reservoir for HBV. It has been reported that after a year 
of therapy with NRTIs, zero to three percent of patients experience a functional cure. Additionally, NRTIs reduce, but do not eliminate, the risk of HBV 
associated liver failure and liver cancer. Despite its low utilization rate, suppressive therapy with NRTIs for HBV represented over a billion-dollar market 
in 2021. 

An alternative treatment option for chronic HBV is a year-long course of PEG-IFN-α therapy, which results in a functional cure approximately three 
to seven percent of the time. The mechanisms by which PEG-IFN-α, an immune cytokine, achieves a functional cure are not known, but there is additional 
evidence supporting the need for immune stimulation to achieve a functional cure. 

HBV Life Cycle and Undetectable HBsAg as a Clinical Endpoint 

The viral life cycle of HBV is shown in the figure below. After infecting a cell, the virus forms cccDNA. This form of HBV DNA is located in the 

nucleus of hepatocytes and acts like a mini-chromosome. HBV DNA can also integrate into the patient’s DNA. This form of HBV DNA is known as 
integrated DNA, or intDNA. 

HBV lifecycle with inhibition of processes by currently available therapies. Arrows indicate viral life cycle process. Perpendicularly-ended lines indicate inhibition of viral process. 

HBV releases infectious virions and subviral particles, or SVPs, from infected cells. Both virions and SVPs include forms of an HBV protein called 

HBsAg, a blood biomarker that indicates that the HBV cccDNA and/or intDNA in that patient’s hepatocytes are actively making HBV RNA and HBV 
proteins. For a registrational trial to demonstrate a functional cure, the formal endpoint accepted by the FDA, is undetectable HBsAg, defined as less than 
0.05 international units per milliliter, or IU/ml, as well as HBV DNA less than the lower limit of quantification, in the blood six months after the end of 
therapy. Achievement of this endpoint has been shown to predict improved clinical outcomes and the lack of need for further therapy.

VIR-2218 for HBV 

Molecular Characteristics. VIR-2218 is an investigational, single siRNA targeting a conserved sequence of HBV that allows for predicted activity 

against 99.7% of the strains of HBV, including all 10 HBV genotypes. Because this conserved sequence falls within a specific region of the X gene of HBV 
that exists within all four HBV RNA transcripts, VIR-2218 is able to degrade each transcript, and consequently decrease the expression of all proteins 
produced by the virus: X, polymerase, S, and core. VIR-2218 is thus potentially a broad-spectrum, potent antiviral.   

HBV DNA can become integrated into human DNA as intDNA. Because VIR-2218 targets a region of HBV that is conserved in the large majority 

of HBV intDNA, this single siRNA is predicted to be able to prevent the production of HBV proteins derived from intDNA, as well as the production of all 
other HBV proteins from cccDNA. 

We believe that the large amount of HBV protein that is transcribed in liver cells can suppress the immune system. There are at least two potential 

mechanisms by which suppression occurs. The first mechanism is T cell tolerance and exhaustion by the presentation of intracellular HBV antigens on 
hepatocytes. The second is the large quantities of HBV proteins that are released into the blood, especially HBsAg, which may also be immunosuppressive. 
By directly reducing the amount of HBV proteins made, VIR-2218 has the potential to decrease the ability of HBV to suppress the immune system—in 
effect removing a brake on the immune system. In mice models, siRNAs that are able to reduce HBsAg expression can transform an otherwise ineffective 
therapeutic HBV vaccine into one that can functionally cure such mice of HBV, suggesting that HBsAg suppression has the ability to enhance the immune 
response against HBV. 

We believe that VIR-2218 is the only HBV-targeting siRNA currently in development that includes ESC+ technology. We believe this technology 

may be able to enhance the potential safety of VIR-2218. 

Phase 1/2 Trial of VIR-2218. VIR-2218-1001 is an adaptive clinical trial designed to evaluate the safety, tolerability, pharmacokinetics and antiviral 

activity of VIR-2218. The current trial design of VIR-2218-1001 is shown below. We initiated dosing of the Part A portion of the trial for VIR-2218 in 
November 2018.

Status of VIR-2218-1001 trial in healthy volunteers and patients with chronic HBV infection. Arrows indicate trial progression. HBeAg- = hepatitis B virus e-antigen negative; 
HBeAg+ = hepatitis B virus e-antigen positive; MAD = multiple ascending dose; SAD = single ascending dose; SC = subcutaneous. 

This trial currently has completed enrollment of 81 subjects across all three parts. Part A is a single ascending dose design in healthy volunteers. 
Parts B and C are multiple ascending dose designs in patients with chronic HBV on NRTIs. Patients in Part B are hepatitis B early antigen negative, or 
HBeAg negative, and patients in Part C are hepatitis B early antigen positive, or HBeAg positive. Patients in Parts B and C receive two doses of VIR-2218, 
four weeks apart. 

16

 
  
 
  
HBeAg positive patients are generally younger, and thought to have more preserved immune function, as compared to HBeAg negative patients who 

are generally older and have experienced greater immune exhaustion. HBeAg negative patients are also thought to have larger amounts of intDNA 
compared to HBeAg positive patients. 

The primary endpoints across Parts A-C of the trial are safety and tolerability. Key secondary endpoints in Parts B and C include the maximum 

reduction of serum HBsAg from baseline until Week 16 and the number of patients with HBsAg loss or anti-hepatitis B surface antibody seroconversion. 
Patients with chronic HBV who experience a greater than 10% decline from baseline at Week 16 in HBsAg will be followed for up to 32 additional weeks. 

Clinical Trial Status. VIR-2218-1001 is an ongoing clinical trial. 49 healthy volunteers enrolled in Part A of the trial. Each Part A completed cohort 

includes six subjects receiving VIR-2218 and two subjects receiving placebo. All cohorts have completed dosing and follow-up. In the 400 mg cohort, a 
replacement subject was enrolled due to a subject who voluntarily withdrew from the trial. The 900 mg cohort was designed to assess the maximum 
tolerated dose of VIR-2218. 

In Part B of the trial, 24 patients with chronic HBV who are HBeAg negative have been enrolled. Each Part B completed cohort includes three 

patients receiving VIR-2218 and one patient receiving placebo. All cohorts have completed dosing and have completed follow-up. 

In Part C of the trial, eight patients with chronic HBV who are HBeAg positive have been enrolled. Each completed cohort includes three patients 

receiving VIR-2218 and one patient receiving placebo. All cohorts have completed dosing and have completed follow-up. 

Clinical Data. Across healthy volunteers and chronic HBV patients, VIR-2218 has been generally well-tolerated. No clinically significant alanine 
transaminase or ALT abnormalities, which are a marker of liver inflammation, have been observed. In the Part A 900 mg cohort, asymptomatic Grade 1 
ALT elevations with no associated changes in bilirubin, or other markers of liver function, have been observed. Three serious adverse events, or SAEs, 
have been reported, all in Part B. The first, a Grade 2 headache, resolved with intravenous fluids and non-opioid pain medications. This patient had 
additional symptoms of fever, nausea, vomiting and dehydration, assessed by us as consistent with a viral syndrome. The second SAE, a Grade 4 
depression, occurred over 50 days after the last drug dose was administered, and was assessed by us as not related to VIR-2218. The third SAE, a patient 
suicide, occurred 241 days after the last dose of study drug and was assessed by us as not related to VIR-2218. Three Grade 3 adverse events of upper-
respiratory tract infection, chest pain and low phosphate levels in the blood have also been reported. We did not consider any of these Grade 3 events as 
related to VIR-2218. 

The biologic activity of VIR-2218 was assessed by declines in HBsAg. The activity of VIR-2218 through Week 48 for each dose level is shown in 

the graph below. For Parts B and C, the average baseline HBsAg levels were 3.3 log10IU/mL and 3.9 log10IU/mL, respectively. The average decline in 
HBsAg across HBeAg negative and HBeAg positive subjects at Week 16 was 1.5 log10, or an approximately 32-fold reduction. The declines observed in 
HBsAg at Week 16 ranged from 0.97 log10 to 2.2 log10, or an approximately nine to 160-fold reduction, after two 200 mg doses of VIR-2218 given four 
weeks apart. The average HBsAg level at Week 16 was 314 IU/mL, with half of the patients achieving HBsAg values < 100 IU/mL and 5/6 achieving 
HBsAg values < 1000 IU/mL. Five of the 12 patients that achieved HBsAg values of <100 IU/mL maintained it through Week 48. Therefore, even though 
HBsAg levels gradually rebounded, overall, a durable effect was observed.    

17

 
The ability of VIR-2218 to result in substantial and durable declines in HBsAg after only two doses suggests that VIR-2218 has the potential to play 
an important role in the functional cure of chronic HBV. We have initiated and plan to initiate additional clinical trials evaluating VIR-2218 in combination 
with other immunomodulatory agents.

VIR-3434 for HBV 

Molecular Characteristics and Preclinical Data. VIR-3434 is an investigational mAb targeting a conserved region on HBsAg that allows it to 
neutralize strains from all 10 HBV genotypes. VIR-3434 specifically targets the antigenic loop, or AGL, on HBsAg. The AGL helps the virus bind to 
hepatocytes and subsequently infect these liver cells. By binding to the AGL, VIR-3434 prevents viral entry, which prevents the spread of HBV to 
uninfected hepatocytes. VIR-3434, through a process called opsonization, also helps remove HBV virions and SVPs from the blood. Hepatitis B 
immunoglobulin, or HBIG, an approved therapy for preventing reinfection after transplantation and which consists of polyclonal antibodies against HBV, 
acts by similar mechanisms. In vitro, VIR-3434 demonstrates approximately 5000-fold greater potency than HBIG in neutralization assays. As shown in 
the figure below, VIR-3434 is better able to prevent the spread of HBV to uninfected cells in vivo compared to HBIG. 

Progression of infection in primary human hepatocytes with hepatitis B immune globulin or VIR-3434 in vivo. PHH = primary human hepatocytes. 

VIR-3434 also has the potential to activate the immune system, via three different processes. First, due to specialized mutations in the Fc domain of 

VIR-3434, it has the potential to act as a T cell vaccine. VIR-3434, which incorporates 

18

 
 
  
 
 
 
Xencor’s XtendTM and other Fc technologies, has been engineered with mutations that enhance binding to the FcR IIa activating receptor and diminish 
binding to the FcR IIb inhibitory receptor. As such, VIR-3434 is designed to capture virions and SVPs, deliver such virions and SVPs to DCs, and instruct 
these DCs to mature and stimulate T cells that can eliminate HBV infected hepatocytes. Second, VIR-3434 has the potential to act via antibody-dependent 
cell cytotoxicity, or ADCC. In this process, by binding to HBsAg at the cell surface, VIR-3434 recruits natural killer cells to eliminate infected hepatocytes. 
The Fc domain of VIR-3434 has been engineered to promote ADCC. Third, by reducing the amount of HBsAg in the blood, VIR-3434 has the potential to 
remove a brake on the immune system by decreasing the ability of HBV to suppress it.  

We have also evaluated the antiviral activity of the combination of VIR-2218 and VIR-3434 in an adeno-associated virus-HBV mouse model. As 

shown in the figure below, VIR-2218 and VIR-3434 work together to reduce the level of HBsAg. 

VIR-2218 and VIR-3434, which was modified to have a mouse mAb backbone for this experiment, administered alone or together result in reduced HBsAg in a mouse model. 

Phase 1 Trial of VIR-3434. VIR-3434-1002 is an adaptive clinical trial designed to evaluate the safety, tolerability, pharmacokinetics and antiviral 

activity of VIR-3434. The current trial design of VIR-3434-1002 is shown below. We initiated dosing of the Phase 1 trial in May 2020.

The Phase 1 clinical trial has four parts. Part A is a single ascending dose design in healthy volunteers. Parts B and C are single ascending dose 

designs in patients with chronic HBV on NRTIs. Patients in Part B will have HBsAg levels less than 1,000 IU/ml for the 6 mg cohort, or less than 3,000 
IU/mL for the other cohorts. It is possible that patients with lower HBsAg levels will have a more profound response to VIR-3434 than patients with higher 
HBsAg levels. Patients with 

19

 
 
 
 
HBsAg levels greater than or equal to 3,000 IU/ml may be evaluated in an optional Part C. In Part D, patients with HBV DNA greater than or equal to 
1,000 IU/mL who are not currently receiving antiviral therapy will be evaluated. 

VIR-3434-1002 is an adaptive clinical trial design in healthy volunteers and patients with chronic hepatitis B virus infection. Arrows indicate trial progression. SC = subcutaneous. 
SAD = single ascending dose. IV = intravenous. 
(1) The six mg SC cohort in Part B enrolled participants with screening HBsAg less than 1,000 IU/ml. 
(2) The 18 mg SC cohort in Part C enrolled participants with any screening HBsAg. 

The primary endpoints across all parts of the trial are safety and tolerability. The key secondary endpoint in Parts B and C is the maximum reduction 

of serum HBsAg from baseline. In Part D, an additional key secondary endpoint is the maximum change of HBV DNA from baseline.  

Clinical Data. To date, all Part A cohorts have completed dosing up to 3,000 mg administered intravenously. The trial’s Safety Review Committee, 

or SRC, has reviewed blinded safety data for at least two weeks post dose from all Part A cohorts. Based on this data, VIR-3434 was generally well 
tolerated in healthy volunteers with no clinical safety concerns. The majority of adverse events, or AEs, were Grade 1, and no Grade ≥ 3 AEs or SAEs were 
reported. No clinically significant effects on laboratory or electrocardiogram parameters were observed. All dose levels were associated with an acceptable 
safety and tolerability profile, as determined through a blinded review of data by the SRC.  

In November 2021, we announced additional preliminary data from Part B in patients with chronic HBV on NRTIs receiving six mg, 18 mg, or 75 
mg VIR-3434 or placebo. Blinded data for eight patients per cohort, two of whom received placebo and six of whom received a single dose of VIR-3434, 
showed that most patients rapidly achieved a > 1 log10 IU/mL decline in HBsAg within approximately 1 week post-dose, with most patients achieving 
HBsAg < 100 IU/mL at nadir. The largest and most sustained reductions in HBsAg were observed in the 75 mg cohort, in which mean reductions were 1.96 
log10 IU/mL at nadir and 1.5 log10 IU/mL at Day 29. VIR-3434 was generally well tolerated, and all adverse events were Grade 1 or 2. The ability of a 
single dose of VIR-3434 to markedly lower HBsAg demonstrates VIR-3434 has the potential to play an important role in the functional cure of HBV. 
Additional data are expected in the first half of 2022.

Other HBV Combinations and New Product Candidates 

Phase 2 Trial of VIR-2218 in combination with PEG-IFN-α. VIR-2218-1001 Parts D and F is a clinical trial evaluating the safety, tolerability, 

pharmacokinetics and antiviral activity of VIR-2218 alone and in combination with PEG-IFN-α in patients with chronic HBV infection on NRTIs. We 
initiated the dosing in the trial in July 2020. We decided not to pursue Part E evaluating 50 mg of VIR-2218.

20

 
 
  
VIR-2218-1001 Parts D and F will evaluate multiple doses of VIR-2218 200 mg, alone or in combination with PEG-IFN-α starting on Day 1 or at 

Week 12. The trial cohorts are shown below. 

VIR-2218-1001 Parts D and F are evaluating multiple doses of VIR-2218 alone or in combination with PEG-IFN-α in patients with chronic hepatitis B virus infection.  

In November 2021, we announced additional data on our ongoing Phase 2 trial of 64 virally-suppressed adults with chronic HBV infection assigned 
to receive subcutaneously injected VIR-2218 alone or in combination with PEG-IFN-α for 24 weeks (cohort 1F). VIR-2218 in combination with PEG-IFN-
α for 24 weeks from Day 1 resulted in a more rapid and substantial decline in HBsAg compared to VIR-2218 alone. Forty-eight of the 52 patients (92%) 
that completed 24 weeks in treatment achieved HBsAg < 100 IU/mL, 3 of these participants had HBsAg < LLOQ, including 2 that had anti-HBs 
seroconversion. The treatment regimen resulted in no new safety signals. The data continue to support the promising safety profile and potential durable 
response. Additionally, new findings also demonstrate that concurrent initiation of VIR-2218 and PEG-IFN-α therapy resulted in substantial HBsAg 
reductions compared to VIR-2218 alone or with PEG-IFN-α following a VIR-2218 lead-in. Additional data are expected in the first half of 2022.

Phase 2 Trial of VIR-2218 in combination with VIR-3434. In July 2021, we initiated the Phase 2 MARCH trial to evaluate the combination of VIR-

2218 and VIR-3434 as a functional cure regimen for chronic HBV infection. We believe VIR-2218 and VIR-3434 have the potential to act in concert by 
inhibiting virion production, removing potentially tolerogenic HBV proteins, and stimulating new HBV specific T cells. Initial data are expected in the first 
half of 2022. As some of our clinical trial sites are in Ukraine and Moldova, we are monitoring the situation to determine any impact resulting from the 
current conflict in this region. 

VIR-3434 18-75 mg dosing in Part A, dosing TBD for Part B; VIR-2218 200 mg dose in Part B; PEG-IFNα 180 mcg dose in Regimen 5. QW= weekly; Q4W = every four weeks. 
*Not exhaustive - additional cohorts may be added

Other Collaborators. In December 2021, we and Gilead initiated a multi-center, open-label Phase 2 clinical trial which is designed to evaluate the 

safety, tolerability and efficacy of various combinations of VIR-2218, selgantolimod, nivolumab and TAF in adults with chronic HBV. The trial will enroll 
approximately 120 patients ages 18 to 65 who are either viremic or are virally suppressed on an approved HBV NUC reverse transcriptase inhibitor. 
Patients who are hepatitis B e antigen (HBeAg)-positive (an indicator of acute viral replication), as well as those who are HBeAg-negative, will be 
enrolled. The primary efficacy endpoint is the proportion of patients who achieve a functional cure (defined as HBsAg loss and HBV DNA <20 IU/mL at 
follow-up week 24). 

In April 2021, Brii Bio initiated a Phase 2 trial of VIR-2218 in combination with BRII-179, an investigational T cell vaccine, for the treatment of 

chronic HBV infection. Initial data are expected in the second half of 2022. 

Furthermore, in parallel with the above development programs, research efforts are underway to use our innate immunity platform to identify and 

disrupt the host proteins necessary for HBV cccDNA formation and stability, which we believe could result in a complete cure. We also have an HBV 
therapeutic vaccine that leverages our T cell platform in preclinical development. This exemplifies the potential value of combining outputs from our four 
technology platforms to complex infectious diseases. 

Universal Prophylaxis for Influenza A 

Summary 

We are developing VIR-2482 as universal prophylaxis for influenza A. VIR-2482 is a mAb that targets a conserved region of the influenza A 

hemagglutinin protein and consequently has the potential to prevent illness from any strain of influenza A, including seasonal and pandemic strains. In 
vitro, VIR-2482 has been shown to cover all major strains of influenza A that have arisen since the 1918 Spanish flu pandemic. Since flu vaccines have 
incomplete strain coverage and limited efficacy, the broad coverage of VIR-2482 may allow it to achieve higher protection levels and for it to be used year 
after year. In addition, because VIR-2482 is an antibody that can directly confer protection, it does not rely on a person to create his or her own antibodies. 
Thus, we believe VIR-2482 has the potential to be effective even in a person with a compromised immune system. VIR-2482 has been half-life engineered 
so that a single dose has the potential to last the entire flu season, which is typically five to six months long. VIR-2482 is currently in a Phase 1/2 clinical 
trial. VIR-2482 has been well-tolerated in the approximately 100 healthy volunteers dosed in Phase 1. Anticipating an increase in the incidence of influenza 
in the Northern Hemisphere this coming winter, we expect to initiate Phase 2 in the second half of 2022. 

In May 2021, we signed the 2021 GSK Agreement to expand our existing collaboration to include the research and development of new therapies 

for influenza and other respiratory viruses. See the section titled “Our Collaboration, License and Grant Agreements—Collaboration Agreements with 
GSK” for a description of the 2021 GSK Agreement.

Disease Overview and Limitations of Current Standard of Care 

According to the WHO, on average, each year the influenza virus is estimated to infect 1 billion people and results in 290,000 to 650,000 deaths 

globally. According to the CDC, in the 2018-2019 flu season, despite the availability of the flu vaccine, approximately 36 million people were diagnosed 
with influenza, 500,000 people were hospitalized, and 34,000 people died from influenza in the United States alone. Thus, more Americans died of 
influenza in the 2018-2019 flu season than from prostate cancer in all of 2019. The large majority of these influenza-related deaths occurred in the elderly 
and/or those with comorbidities at high risk for severe disease. These patients comprise a population with a high unmet need for better preventive 
measures. For example, there are 16 million Americans with a known diagnosis of chronic obstructive pulmonary disease, the care of whom is estimated to 
directly cost up to $49 billion annually. Up to 12% of chronic obstructive pulmonary disease acute exacerbations are thought to be attributable to influenza. 
Overall, it is estimated that the annual influenza-related economic burden is approximately $87 billion. 

There are two major types of influenza virus: type A and type B. Influenza A has been associated with more severe illness and has been the source 

of all known influenza pandemics. A recent study of influenza hospitalized patients from 2016-2020 published by the BMC Infectious Diseases showed 
that 88% had influenza A and 12% had influenza B.  

According to the CDC, the efficacy of the seasonal flu vaccine has ranged from 10% to 60% over the past 16 years, with an average of 40%, overall, 

across all populations. The seasonal flu vaccine's efficacy in the elderly, defined as those 65 and older, has been found to be notably lower, in some flu 
seasons as low as 10%. The limited success rate of influenza vaccines has been attributed to two primary factors. First, flu vaccines have incomplete strain 
coverage and therefore often do not provide protection against all strains of influenza that circulate in a given season, despite being updated every year. 

22

 
Second, flu vaccines are active immunizations that rely on a person's own immune system to create protective influenza virus antibodies, and many 
individuals do not generate an effective immune response. Clinical and technological advances in flu vaccines, such as cell-based manufacturing, mRNA-
based vaccines and higher dose administration, do not address these two fundamental limitations. 

VIR-2482 for Influenza A 

Molecular Characteristics and Preclinical Data. VIR-2482 is an investigational mAb targeting a functionally conserved epitope on the influenza A 

hemagglutinin protein located within the stem region. We believe that all strains of influenza, past and future, have and likely will contain this conserved 
epitope within the stem region. In preclinical studies, we have demonstrated that, in vitro, VIR-2482 covers all the major strains of influenza A that have 
arisen since 1918. Thus, unlike flu vaccines, whose incomplete strain coverage results in limited efficacy despite being updated every year, the broad 
coverage of VIR-2482 may allow it to achieve higher protection levels and to be used year after year. In addition, because VIR-2482 is an antibody that can 
directly confer protection, it does not rely on a person to create his or her own antibodies. Thus, we believe VIR-2482 has the potential to be effective 
irrespective of the status of a person’s immune system. 

Notably, in a 2019 clinical epidemiology study, it was observed that the presence of rare, stem-binding influenza antibodies correlated with 

protection from influenza infection.

VIR-2482 targets a highly conserved region of the influenza virus and exhibits potency against the last century of influenza viruses. Following vaccination, most anti-influenza 
antibodies target the variable head region. VIR-2482 binds to the stem region which is highly conserved over time. HA = hemagglutinin. 

23

 
 
 
 
While other stem-binding influenza A antibodies have been identified, we have demonstrated that VIR-2482 has the broadest coverage when 

compared to a large representative panel of stem-binding mAbs. In prophylactic lethal challenge studies of influenza A in mice, VIR-2482 was able to 
protect mice from death at VIR-2482 exposures we believe to be clinically relevant. We have also demonstrated that the parent form of VIR-2482, an 
antibody that has the same antibody binding domain (Fab) as VIR-2482, has, in general, greater potency, when compared to three other stem-binding 
mAbs, as shown in the figure below. 

Neutralization potency of four stem-binding antibodies. VIR-2482, and three other third-party antibodies, CR9114, 39.29, and FI6v3, were tested for their neutralization potency 
against 24 representative strains. These strains were selected to cover the antigenic variation of the seasonal H1N1 and H3N2 strains back to 1938 and 1968, respectively, and strains 
from other subtypes that infected humans in past pandemics or that caused sporadic animal-derived outbreaks. 

We engineered the parent form of VIR-2482 to extend its half-life to create VIR-2482, which incorporates Xencor’s XtendTM technology. This half-

life extension potentially allows for a single injection of VIR-2482 given at the start of the influenza season to maintain a protective concentration in the 
respiratory tract for the duration of the influenza season. 

24

 
 
 
  
Phase 1/2 Trial of VIR-2482. VIR-2482-3001 is a clinical trial designed to evaluate the safety, tolerability, pharmacokinetics and efficacy of VIR-
2482. The current trial design of VIR-2482-3001 is shown below. This trial is designed to include up to 2,860 healthy volunteers across the Phase 1 and 
Phase 2 portions.

The Phase 1 portion of this trial is a single ascending dose trial in healthy adult volunteers with endpoints of safety, tolerability, and 

pharmacokinetics, or PK, when VIR-2482 is administered IM. Healthy volunteers in the Phase 1 portion may receive a second dose, one year later, to 
evaluate for the possibility of anti-drug antibodies. The Phase 2 portion of this trial is planned to be a dose-ranging, double-blind, placebo-controlled trial in 
healthy adult volunteers. The primary efficacy endpoint of the Phase 2 portion is laboratory-confirmed influenza A illness with key secondary endpoints of 
severity and duration of illness due to influenza A.      

VIR-2482-3001 clinical trial design in healthy adult volunteers. 

We initiated dosing of the Phase 1 portion of the trial in August 2019 and have completed enrollment of all four dose cohorts (60 mg, 300 mg, 1200 

mg, and 1800 mg) and subjects remain in follow-up. Overall, VIR-2482 was well-tolerated and is estimated to have a half-life of 58 days based on 
preliminary clinical data. Anticipating an increase in the incidence of influenza in the Northern Hemisphere this coming winter, we expect to initiate the 
Phase 2 portion of the trial in the second half of 2022.    

Vaccine for HIV Prophylaxis 

Summary 

We are developing a vaccine to prevent HIV. We have designed VIR-1111 to elicit T cells that recognize HIV epitopes that are different from those 
recognized by prior HIV vaccines and to stimulate a different and specific type of T cell immune response to HIV, known as an HLA-E restricted immune 
response. An HLA-E restricted immune response has been shown to be associated with protection of NHPs from SIV. In December 2020, we initiated a 
Phase 1 trial for VIR-1111. VIR-1111 is a proof of concept vaccine, because, at minimum, changes to the vaccine antigen from HIV will be required before 
starting subsequent phases of clinical development. The need to alter the antigen within VIR-1111 or other aspects of the vaccine design to allow for further 
clinical development will require additional Phase 1 work with the altered product candidate. That Phase 1 clinical trial is currently estimated to begin two 
years after the commencement of the VIR-1111 Phase 1 clinical trial, adding approximately two years to any potential regulatory approval timeline for an 
HIV vaccine product candidate. 

Disease Overview and Limitations of the Current Standard of Care 

According to UNAIDS, each year there are approximately 1.5 million new cases of HIV and approximately 700,000 HIV-related deaths globally. 

Unless treated, infection with HIV results in an almost universally fatal disease, acquired immune deficiency syndrome, or AIDS. According to the World 
Health Organization, almost 36 million people have died from HIV-related illnesses globally.

25

 
 
 
  
  
Highly effective HIV treatments are now available, but these medicines only suppress HIV and are not curative. They require life-long 

administration and carry the risk for viral breakthrough and resistance. Furthermore, while HIV prevention programs based on behavioral modification, 
pharmacological intervention, use of barrier devices and other methods continue to be developed, such approaches have had at most a modest effect on 
HIV transmission globally in high-risk populations. Therefore, we believe the most effective means of curbing the worldwide HIV epidemic would be a 
safe and effective vaccine for individuals who are or may become sexually active. We believe that the target population for an HIV vaccine is comprised of 
billions of individuals and is potentially larger than the target population for Gardasil®, a vaccine to prevent human papillomavirus and the cancers human 
papillomavirus causes, due to the higher lethality associated with HIV. In 2020, Gardasil® revenue approximated $4.0 billion. Despite nearly 30 years of 
intensive efforts, no vaccine for HIV has been successfully developed. 

VIR-1111 for HIV 

Molecular Characteristics and Preclinical Data. VIR-1111 is a proof of concept T cell vaccine based on HCMV that is designed to elicit T cells that 

recognize parts of HIV epitopes that are different from those recognized by prior HIV vaccines, and to stimulate a different and specific type of T cell 
immune response to HIV, known as an HLA-E restricted immune response. In NHP models, T cell vaccines based on an RhCMV elicited T cells that 
recognized 3-4 times the number of epitopes compared to other vaccine platforms; the specific epitopes recognized were also different, as shown in the 
figure below. SIV is the NHP equivalent of HIV.  

Number of epitopes recognized by T cells using RhCMV compared to other vaccine vector technologies or NHPs naturally achieving SIV control. Each line represents a different 
NHP. Each box denotes the relative location of the epitope within the antigen that is recognized by the T cells elicited by that vaccine vector or SIV. The total number of epitopes 
recognized is shown on the right. RM = rhesus macaque; SIVmac239-controller = infected with a virulent strain of SIV; EP DNA/gag = electroporation of DNA expressing the SIV gag 
protein; Ad5/gag = Adenovirus type 5 expressing the SIV gag protein; MVA/gag = Modified vaccinia virus Ankara expressing the SIV gag protein. 

Further, in such NHP models, introducing different mutations to RhCMV allows the vector to be programmed to elicit an HLA-E restricted immune 
response. An HLA-E restricted immune response has been shown to be associated with protection of NHPs from SIV. In these series of experiments, large 
groups of NHPs were given an RhCMV-based vaccine, which protected more than 50% of the NHPs from repeated exposure to SIV. 

Preliminary data suggest the ability to predict which NHPs will be protected from SIV after administration of the RhCMV-based vaccine. This is 
made possible using transcriptomic signatures, a blood test that evaluates how cells in the body respond to the vaccine. Transcriptomic signatures will be 
analyzed in human clinical trials. If protection effectiveness is found to be less than 100%, such data may allow us to predict who will be protected as well 
as to generate next-generation vaccines.

Phase 1 Trial of VIR-1111. VIR-1111-2001 is a multiple ascending dose clinical trial designed to evaluate the safety, tolerability, reactogenicity and 
immunogenicity of VIR-1111 in CMV-positive healthy adult volunteers. The immunogenicity evaluation includes an assessment of the breadth and nature 
of the T cell response to the vaccine. The current trial design of VIR-1111-2001 is shown below. We initiated a Phase 1 clinical trial for VIR-1111 in 
December 2020. The manufacture and early clinical development of VIR-1111 is funded by the Bill & Melinda Gates Foundation. Modifications to VIR-
1111 will be required before subsequent phases of clinical development, as VIR-1111 is a proof of concept vaccine and will not in its current format result 
in a commercial product. No safety signals have been reported to date and we expect to have additional clinical data in the first half of 2022.

Technology Platforms 

Platforms for the Creation of Transformative Medicines for Infectious Diseases 

We have purposefully assembled a portfolio of technology platforms that we believe will, individually or in combination, allow us to stimulate and 

enhance the immune system in innovative ways and to exploit the vulnerabilities of pathogens. Our current platforms are focused on antibodies, T cells, the 
innate immune response and siRNAs. We have assembled these platforms through internal development, collaborations and acquisitions. We are using our 
platforms, and continue to evaluate others, to advance our current product candidates and generate additional product candidates for multiple indications. 

We follow the science to select the modality, or combination of modalities, that gives us the highest chance of success for a specific infection in a 

given patient population. The diversity of our different platforms allows us to select the best modality or modalities for a given clinical need. 

Antibody Platform 

Overview 

We are using specialized mAbs to treat or prevent rapidly evolving and/or previously untreatable pathogens. These mAbs act in a variety of ways, 

including direct pathogen neutralization and immune system stimulation. We combine high-throughput, rapid isolation of rare, highly potent, broad-
spectrum and fully human antibodies with targeted engineering to enhance their therapeutic potential. We expect that these specialized mAbs can be 
administered to transfer protective immunity to all at-risk individuals. 

We expect the following benefits from our antibody platform: 

•

•

•

•

•

•

Effective regardless of an individual’s ability to generate his or her own immune response 

Diminished likelihood of self-reactivity because they are selected in humans 

Broad coverage of most or all strains of a pathogen, or even multiple pathogens 

High affinity binding to conserved pathogen antigens, resulting in a high barrier to resistance 

Longer half-life than naturally occurring antibodies 

Potential to induce a vaccinal effect, i.e., to elicit continued protection even after the mAb is no longer present 

27

 
 
 
 
Sotrovimab (previously VIR-7831), VIR-7832, VIR-3434 and VIR-2482 were generated using our antibody platform. 

Our Approach 

We use a proprietary antibody screening technology that allows us to characterize the antibodies produced from hundreds of millions of B cells 

derived from survivors of an infection to identify those rare antibodies that have the characteristics needed to create an effective medicine. Rare 
characteristics include, for example, the ability to bind to a highly conserved antigen within a pathogen and the ability to neutralize multiple different 
pathogens. We refer to this technology as High Throughput Isolation since we are able to screen hundreds of millions of B cells to find rare antibodies in 
just weeks. 

Following isolation, we clone the antibody genes and express the resulting fully human antibody for further trials, engineering and development. 

We have applied these methods to identify mAbs for a range of pathogens including SARS-CoV-2, HBV, influenza A and influenza B virus, Ebola, 

RSV, malaria, clostridium difficile, Staphylococcus aureus, Klebsiella pneumoniae, and Acinetobacter spp. Examples of the power of this platform are 
Xevudy® (sotrovimab, formerly known as VIR-7831), our anti-SARS-CoV-2 mAb, and Ebanga (ansuvimab-zykl, formerly known as mAb114), the anti-
Ebola virus mAb identified by our scientists in collaboration with the NIH and others and marketed by Ridgeback Biotherapeutics LP.

Precision Antibody Engineering to Create the Best Medicines 

Our strategy is to optimize both the Fab and Fc domains of a mAb to generate the best medicine to treat or prevent infection. Having isolated a rare, 

fully human antibody via High Throughput Isolation, we then engineer as desired both parts of the mAb, the Fab and Fc domains, to enhance efficacy, 
potency and manufacturability. The Fab portion binds to the protective antigen on the pathogen. The Fc portion binds to effector proteins and cells in the 
body to engage the immune system in killing and clearing the infection. 

Fab engineering is performed to further increase mAb potency and breadth of coverage. mAb potency and breadth are based on the epitope bound, 
affinity of binding and valency. In some cases, it may be valuable to create mAbs that bind to more than one epitope, so-called “multi-specific” mAbs, by 
engineering the Fab region. There are many approaches to creating multi-specific antibodies, and we are exploring a number of them, including some that 
naturally occur in people. We believe that naturally occurring multi-specific antibodies can be leveraged to create new and potent therapeutics and to 
enhance antibody prophylaxis of disease, and have the potential for higher manufacturing yields and better pharmacokinetics in patients, as compared to 
artificial multi-specific formats currently being developed. 

Fc engineering selects and optimizes the specific ways in which mAbs engage Fc receptors, or FcRs, which in turn govern “effector functions” such 

as the half-life of the antibody and the way that the immune system is recruited by the mAb to fight infection. Effector functions can be enhanced or 
reduced via Fc mutations that alter the binding affinity of the Fc domain of a mAb to the various FcRs, based on a detailed understanding of the role of 
individual FcRs in half-life and immunity. Examples of immunity that can be altered in this way include the recruitment of serum proteins to infected areas, 
phagocytosis and destruction of viruses and viral particles, the killing of virus-infected cells through a process known as ADCC and the presentation of 
antigens to elicit B and T cell immunity. 

28

 
 
 
 
Antibodies as T Cell Vaccines 

We are using Fc engineering to create antibodies that are designed to not only directly treat or prevent infection but also to immunize an infected 

individual against future infections. We refer to this property as a vaccinal effect, i.e., eliciting continued protection even after the mAb is no longer 
present. This technology benefits from the fact that FcRs on specialized antigen-presenting cells, which are called dendritic cells, or DCs, internalize 
complexes of antibody and antigen. Our strategy leverages the observation that different FcRs on antigen presenting cells can bind different parts of the Fc 
portion of the mAb. By engineering the Fc region, we can select which FcRs interact with the antibody-antigen complex to generate activated DCs that we 
believe can effectively induce T cell immunity. 

Design and mechanism of vaccinal antibodies intended to induce enhanced immunity through induction of T cells. The Fc portion of mAbs interacts with FcRs on DCs to trigger 
uptake of antigen and induction of T cells. Engineering of the Fc portion of the mAb is predicted to increase the induction of T cells by these DCs. 

Specific vaccinal mutations in the Fc domain can enhance immune responses to a pathogen in two ways. First, the mAb can deliver increased 

amounts of antigen to DCs. Second, FcRs deliver signals that activate DCs. In turn, activated DCs can stimulate T cells specific to the delivered antigen, 
resulting in T cell immunity. In this way, an antibody with vaccinal mutations can potentially actively immunize infected patients. The in vivo data 
supporting enhancement of the vaccinal effect through Fc mutants has been demonstrated by others in a CD20 positive tumor model, using mice with 
humanized Fc receptors. In this experiment, anti-CD20 mAbs and CD20 tumor cells were administered to mice months before being later rechallenged 
with a lethal dose of CD20 tumor cells. 80% of the mice who received a mAb with Fc mutants that enhanced binding to activating FcRs IIa and IIIa 
survived. Conversely, 70% or more mice who received a mAb without the enhancing Fc mutations died. This durable protection is believed to be the result 
of the induction of a T-cell response. We are testing this technology in chronic HBV infection with VIR-3434 and in COVID-19 infection with VIR-7832, 
and if it performs as expected, we believe it may have applicability to multiple other infections including influenza and HIV.  

T Cell Platform 

Overview 

T cells can prevent or control infection and cancer. T cells are diverse in how they sense pathogens and cancer cells, the tissues that they protect and 

the effector functions that they use to control infection or cancer. Our approach is to use HCMV as a vaccine vector to potentially treat and prevent 
infection by pathogens refractory to current vaccine technologies because HCMV may induce potent and long-lasting T cell responses to a broader range of 
epitopes than observed for other viral vaccines. In addition, we can make proprietary modifications in the HCMV genome that we expect will elicit 
different types of pathogen-appropriate T cell responses. Experiments in NHPs demonstrate the ability of vaccine vectors based on the closely related 
RhCMV to protect against SIV, a close relative of HIV, and TB, two of the most challenging infections for which to create effective vaccines. 

HCMV infects a large proportion of the human population and causes a life-long asymptomatic infection that typically causes no harm. This is due 

to millions of years of co-evolution between the virus and host in which the virus evades 

29

 
 
 
 
sterilizing immunity using specialized viral genes, while at the same time allowing the generation of certain T cell responses that prevent HCMV infection 
from becoming lethal. 

We expect the following benefits from our T cell platform: 

•

•

•

•

•

•

•

•

Highly potent and long-lived T cell responses throughout the body 

Induction of high numbers of specialized T cells, known as effector memory cells, that allow control of disease in the first few days after 
infection 

Immune responses to three- to four-fold more antigenic epitopes in a target protein than other viral vectors 

Programmable T cell responses allowing selection of the type of T cells elicited 

Generation of universal T cells that may be active in most or all people despite high genetic variability between people in immune response 
genes 

Opportunity for repeated vaccination using the same backbone HCMV vector against different infections 

Opportunity to use the same vaccine to protect against multiple pathogens 

Potential to induce responses even to proteins that the host is tolerant of, such as self-proteins expressed in a tumor 

VIR-1111 was generated using our T cell platform. 

Our Approach 

We believe that the type of T cell response elicited by an HCMV-based vaccine vector can be selected by mutating certain genes in HCMV. We term 

this approach “immune programming.” We believe that immune programming is critical to combatting infections such as HIV and TB that have proven 
intractable, to date, for other vaccine technologies. 

Immune programming is best understood in the context of the normal processes that elicit T cell immunity. T cells that fight infection and cancer are 

elicited by DCs, as well as other types of cells. The elicited T cells detect small peptide fragments from antigens on the surface of DCs and other antigen 
presenting cells, which have been captured in grooves found within specialized proteins encoded by major histocompatibility complex, or MHC, genes. 

The unique immunology of HCMV depends on the virus’s ability to regulate the normal immune processes of antigen presentation by MHC genes. 

HCMV contains multiple genes that regulate many of the steps in antigen presenting cells that elicit T cell immunity by altering antigen presenting cell 
biology, the types of antigen presenting cells infected by the viral vaccine and the mechanisms responsible for the ability of a T cell to recognize antigens 
together with MHC molecules. Through manipulation of the HCMV genome, we believe we can program different types of pathogen-appropriate T cell 
responses. 

MHC-E as a Near-Universal Target for Medicines that Leverage T Cell Receptors 

T cells need to be able to recognize a highly diverse set of pathogen proteins to be effective. This diversity comes from the use of multiple different 

host immune response MHC genes to present foreign antigens to T cells. Some immune response MHC genes are highly variable between individuals, 
while others are less variable between individuals as illustrated below. The immune response MHC genes that are highly variable between individuals are 
responsible for most T cell responses. These MHC molecules enable T cells to recognize foreign proteins through the use of a highly specialized T cell 
receptor, or TCR, on the T cell surface. 

An important consequence of the inter-individual variation in some immune response MHC genes is that a TCR that recognizes an antigenic peptide 

associated with one person’s MHC molecules could attack even normal tissues of a person with different MHC genes. As a result, identifying universal 
TCRs and universal T cell antigens that work in all people has been very challenging. 

Our T cell platform may enable us to create vaccines or other types of medicines that are near universal in their effects on human immunity. The 

programmed T cell responses elicited by engineered HCMV vectors are predicted to use immune response MHC genes that vary minimally between 
people, instead of the highly variable immune response MHC genes 

30

 
targeted by other types of vaccines. As demonstrated by the graphic below, TCRs recognizing antigenic peptides together with MHC-E may be functional 
in all individuals, potentially allowing for the generation of universal TCR-based medicines, such as off-the-shelf cancer cell therapy. The peptides 
presented by MHC-E may be immunogenic in all individuals, potentially allowing for the generation of universal infectious disease and cancer vaccines. 

Comparison of standard T cell responses to MHC-E responses. Peptides that are bound to MHC-I, -II or -E proteins are expressed on cell surfaces where they are recognized by T cell 
receptors on T cells (TCRs). This interaction results in the expansion of T cells that can recognize diverse antigen peptides (top row) and that carry out functions that protect the host. 
Since MHC-I and MHC-II molecules are highly variable between people, peptide presentation to TCRs has a high degree of individual specificity, as illustrated by the different colors of 
each peptide in the top row. In contrast to MHC-I and MHC-II, MHC-E proteins (bottom row) are conserved in the human population. 

Specifically programmed RhCMV vectors can elicit strong T cell responses that target MHC molecules which vary minimally between NHPs. One 
such protein is MHC-E. The fundamental discovery, by some of our founders, that enables this part of our T cell platform is that RhCMV responses can be 
programmed to generate abundant MHC-E-restricted T cells. 

We believe that using our T cell programming approach will allow us to select vaccine antigens and to identify TCRs that work across the human 

population. An example of a use of such a TCR would be creating a biological product that specifically recognizes infected cells in all individuals. 

31

 
 
 
 
Programming T Cell Responses to Create HIV and TB Vaccines 

Two of the most challenging infections for vaccine development are HIV and TB. Preclinical studies have demonstrated that programmed RhCMV 
vectors can be used to vaccinate against either SIV or TB in NHPs. For example, as shown in the figure below, in an NHP study, an MHC-E programmed 
RhCMV vaccine effectively protected more than half of NHPs from infection when challenged with a highly virulent form of SIV, under conditions in 
which all animals in the control group became infected. SIV vaccines programmed in other ways were not protective, demonstrating the potential value of 
having a programmable T cell vaccine platform. 

Primary data for the protective effects of RhCMV-derived T cell vaccines on SIV infection. Rhesus monkeys were vaccinated with an RhCMV vaccine that elicits CD8 T cells 
recognizing SIV peptides presented by MHC-E and MHC-II or a control before challenge with SIV by rectal or vaginal routes. SIV genome copies were measured in peripheral blood 
(vertical axis) at intervals after challenge (horizontal axis). SIV infection was cleared in approximately 51% of intrarectal challenged animals and approximately 60% of intravaginal 
challenged animals while the infection was progressive in all unvaccinated controls. 

Protection has also been observed against TB in preclinical studies of NHPs after immunization with either of two different RhCMV vaccines. One 

of the protective vaccines was programmed to elicit MHC-II and MHC-E responses, while the other was programmed to elicit a response depending on 
MHC-I genes. This shows the potential significance of being able to specifically program a T cell vaccine to target a given infection, as the programming 
of a vaccine to protect against SIV can be different from the programming of a vaccine to protect against TB. These preclinical data support our plans to 
use our T cell platform to vaccinate against HIV and TB. 

The Bill & Melinda Gates Foundation is providing funds for the process development and manufacturing and early clinical development of our HIV 

and TB vaccine programs. If proof of concept for the potential efficacy of our T cell vaccine platform is obtained in currently planned clinical trials, we 
plan to apply this T cell platform for treating additional types of infections, as well as potentially even cancers. 

Innate Immunity Platform 

Overview 

Innate immunity protects us during the early stages of infection until antibodies and T cells can be generated by the immune system. Importantly, 

innate immunity is not pathogen-specific. We believe that we can target innate immunity to create medicines that break the “one-drug-for-one-bug” 
paradigm by producing “one-drug-for-multiple-bugs.” We term this concept “host-directed therapy” because the medicine would target a host protein 
instead of pathogen proteins, which are the target of standard antibiotics and antivirals. We can also identify proteins that are critical for a high priority 
infection, such as HBV, for which host-directed therapy might be part of a functional cure or complete cure. This platform may also identify targets relevant 
to diseases outside of infection. 

32

 
 
 
  
Our scientists have developed and applied cutting-edge CRISPR-based genetic technologies to identify host genes that regulate innate immunity 

and/or pathogen replication. We have built internal capacity to systematically extend such trials to multiple pathogens and multiple aspects of innate 
immunity. We have joined the Broad Institute’s Functional Genomics Consortium, which provides us access to cutting-edge CRISPR reagents and 
computational services for whole-genome and custom-designed genetic screens. 

Design of steps in our innate immunity platform. We are systematically mapping the genes that regulate pathogen control across a diverse set of pathogens. To accomplish this, 
advanced gene editing technology (CRISPR) is used to create cell libraries in which individual genes are either knocked out or activated. By exposing these cell libraries to pathogens of 
interest, under different screening conditions, we can systematically create genomic maps that identify genes that could lead to pathogen control. By computationally comparing these 
genomic maps, genes or pathways that are common to multiple pathogens can be identified and could lead to the development of products that could treat more than a single pathogen. 
Human rhinovirus = HRV. 

We expect the following benefits from our innate immunity platform: 

•

•

•

Enhancement of the potency of innate immunity, allowing for control of multiple unrelated pathogens 

High barrier to resistance since the targeted host protein is not likely to mutate 

Identification of key host targets in areas outside of infectious disease 

Our Approach 

Our innate immunity platform envisions three steps leading to new medicines, as illustrated in the figure above. 

Step 1: CRISPR Screens to Map the Genomic Landscape of Infection and Innate Immunity 

Multiple types of proteins participate in innate immunity and infection, as they may be required for entry, replication, gene expression, pathogenicity 

and/or innate immune control of an infectious agent. 

33

 
 
 
 
To identify such proteins, we screen CRISPR-derived cell libraries after infection, treatment with cytokines that trigger innate immunity, or both, 

and then select cells with desired properties. Using next-generation sequencing, we identify genes responsible for the desired property. By combining these 
data across screens and across pathogens, our team has created, and is continuously expanding, a proprietary database of the genomic landscape of 
infection and innate immunity. 

CRISPR screen for genes involved in RSV replication. A CRISPR cell library was prepared in cells in which RSV can replicate. After a period of infection with an RSV strain 
expressing a fluorescent protein which serves as a surrogate for viral replication, cells were separated using flow cytometry into populations in which RSV replication was decreased or 
increased. Deep sequencing of the population exhibiting decreased replication compared to control revealed candidate genes required for efficient replication. Computational analysis 
represented on the right panel revealed that some of these genes fall into nodes that function in specific cellular processes. These nodes are represented as dots interconnected with a 
dense network of lines. 

As an example, to identify genes required for RSV growth, we performed a screen in which a CRISPR-generated cell library was infected with RSV, 

as shown in the figure above. We then purified and sequenced populations exhibiting low or high RSV growth. Sequencing of the RSV low population 
revealed genes potentially required for RSV infection. When analyzed computationally, these genes fell into sets involved in specific cellular processes. 
These genes are potential targets for product candidates. We performed a similar screen with the influenza A virus and HRV and found that certain genes 
are shared between RSV, influenza A virus and HRV. Targeting such proteins might result in a pan-respiratory virus product candidate capable of treating 
RSV, influenza A virus and HRV. 

The result from this step of the innate immune platform is a continuously updated database of the genomic landscape of pathogen replication and 

innate immunity. We have already performed multiple screens, and additional screens and target validation trials are in progress. 

Step 2: Computational Analysis for Identification of Product Targets 

Results from CRISPR screens provide the critical data that helps identify host targets necessary for a given pathogen. When creating a single drug 

for multiple pathogens, host targets in common among multiple pathogens are identified. After having identified the critical set of host targets necessary for 
a pathogen or pathogens, the specific target for a new medicine is selected by computationally integrating diverse data sets that account for tissue gene 
expression, human genetic variation, redundancies in cellular pathways and protein-protein interaction networks, among other factors. 

Step 3: Product Discovery 

Once a specific target has been chosen, the modality used to disrupt the function of the target is then selected. Potential modalities may include 

small molecules, antibodies or siRNAs. Standard drug discovery efforts are then applied to identify a lead product candidate. Alternatively, machine 
learning and database mining can be used to identify pre-existing chemical matter that is already known to inhibit an identified host target. This chemical 
matter can then be verified as having 

34

 
 
 
  
anti-pathogen activity, and serve as a lead compound. There are two potential outcomes from Step 3: one-drug-for-one-bug and one-drug-for-multiple-bugs. 

siRNA Platform 

Overview 

Gene expression can be altered by two main types of synthetic oligonucleotides: (i) antisense oligonucleotides; and (ii) siRNAs. We believe that our 

current approach leveraging siRNAs may have safety and potency advantages over antisense oligonucleotides. The first FDA-approved siRNA in the 
United States was ONPATTRO® (patisiran), which was developed by our collaborator, Alnylam. 

Mechanism of siRNA action to regulate gene expression. Intracellular double stranded RNA, or dsRNA, is processed by the “dicer” complex to produce siRNAs that become integrated 
into a multi-subunit protein complex, the RNA-induced silencing complex, or RISC, which guides the siRNAs to the target messenger RNA, or mRNA, sequence. The siRNA duplex 
unwinds, and the antisense strand remains bound to RISC and directs site-specific cleavage of the target complementary mRNA sequence, resulting in mRNA degradation and reduced 
expression of the target protein. (A)n = polyadenylation. 

siRNAs act via an RNA interference, or RNAi, mechanism involving sequence-specific knockdown of target RNAs. Our bodies create their own so-
called endogenous siRNAs, which act via the RNAi mechanism. This RNAi mechanism can be exploited by chemically synthesizing synthetic siRNAs that 
are introduced as medicines to knock down target RNAs that express pathogen or host proteins of interest. Pursuant to our collaboration and license 
agreement with Alnylam, we have an option to license Alnylam’s siRNA technology for use in up to four other infectious disease targets in addition to 
VIR-2218 for HBV. See the section titled “Our Collaboration, License and Grant Agreements” for a description of the collaboration and license agreement. 

We expect the following benefits from our siRNA platform and siRNAs generally: 

•

•

•

Cutting-edge siRNA design, through collaboration with Alnylam 

Direct anti-pathogen activity and potential for immunomodulation 

Diminished off-target siRNA effects via use of next generation ESC+ technology as a differentiator compared to other siRNA approaches, 
which has the potential to increase the therapeutic index 

35

 
 
 
 
•

•

Efficient targeting of siRNAs to the liver using GalNAc technology 

Extended effects of siRNA may last for weeks to months in humans 

VIR-2218 was generated using our siRNA platform. 

Our Approach 

We have elected to develop modified siRNAs initially for infectious diseases of the liver because these product candidates can be administered 
subcutaneously, are highly stable in the blood stream and are efficiently delivered into hepatocytes via GalNAc sugar modification. Once in a liver cell, the 
siRNA can act to reduce pathogen or host gene expression. Such siRNAs can be further modified to reduce off-target activity, and potentially increase the 
therapeutic index. Since October 2017, we have collaborated with Alnylam to leverage this validated technology, with the goal of eliminating key host 
factors necessary for pathogen survival and removing microbial immune countermeasures. 

We believe that HBV persists in part due to the expression of viral proteins such as HBsAg, which potentially inhibit antibody, T cell, and innate 
immune responses. This prevents the immune response from clearing HBV. By inhibiting the expression of these viral proteins, we envision enhancing 
immune function in persistently infected individuals. Furthermore, we believe that combining siRNA therapy with products derived from our other 
platforms, including antibodies, T cells and innate immune modulators, may allow us to rapidly advance a functional cure for HBV. 

siRNA Delivery Mechanism 

Since unmodified synthetic siRNAs can be unstable in the blood stream, methods to stabilize synthetic siRNAs have been pioneered by Alnylam 

including using their ESC technology. 

An approach that has been used successfully to deliver siRNA to liver cells is to conjugate siRNAs to a specific sugar known as a GalNAc, whose 
receptor is exclusively expressed at high levels on hepatocytes, allowing for uptake of large quantities of siRNA into hepatocytes. Importantly, a GalNAc-
conjugated siRNA can be delivered to the liver by subcutaneous injection, making administration relatively simple. 

36

 
Potentially Enhancing the Therapeutic Index by Diminishing Off-Target Activity of siRNAs 

A distinguishing characteristic of VIR-2218 siRNA, and of future siRNAs that we may develop with Alnylam, is the application of a new approach 
to diminish off-target effects of RNAi. siRNAs may cause unwanted alterations to non-target host RNAs, a process known as off-target activity, which can 
result in short- or long-term toxicity. To reduce off-target activity, which is thought to be due in part to microRNA, or miRNA, activity, it is necessary to 
preserve the RNAi activity of an siRNA while simultaneously decreasing its miRNA activity, as shown in the figure below. Alnylam scientists have 
pioneered placement of a modified nucleotide called a glycol nucleic acid, or GNA, into the part of the siRNA that generates miRNA-like activity. GNA 
modification has been shown to reduce miRNA activity, while preserving the RNAi activity of siRNA. The combination of GNA modification and other 
chemical modifications that enhance siRNA stability is called ESC+ technology. In animal models, reducing off-target miRNA activity can result in an 
increased therapeutic index of approximately five-fold. A higher therapeutic index has the potential to allow for higher siRNA doses and/or a longer 
duration of therapy, while maintaining a favorable safety profile. VIR-2218 was the first siRNA to enter the clinic with ESC+ technology. 

On-Target and Off-Target Activity of siRNA. siRNAs can have off-target activity when siRNA binds to mRNA with a partial sequence match, leading to translation repression or mRNA 
destabilization of unrelated messages (right side). This contrasts with the intended on-target activity of an siRNA, which binds to an mRNA through a match to the entire sequence, 
leading to mRNA cleavage (left side). mRNA = messenger ribonucleic acid; RISC = ribonucleic acid-induced silencing complex. 

Our Collaboration, License and Grant Agreements 

Collaboration Agreements with GSK

2020 Collaboration Agreement with GSK

In June 2020, we entered into a definitive collaboration agreement with GSK, or the 2020 GSK Agreement, pursuant to which we agreed to 
collaborate to research, develop and commercialize products for the prevention, treatment and prophylaxis of diseases caused by SARS-CoV-2, the virus 
that causes COVID-19, and potentially other coronaviruses. The collaboration is focused on the development and commercialization of three types of 
collaboration products under three programs: (1) antibodies targeting SARS-CoV-2, and potentially other coronaviruses, or the Antibody Program; (2) 
vaccines targeting SARS-CoV-2, and potentially other coronaviruses, or the Vaccine Program, and (3) products based on genome-wide CRISPR screening 
of host targets expressed in connection with exposure to SARS-CoV-2, and potentially other coronaviruses, or the Functional Genomics Program. The 
initial antibodies under the Antibody Program are sotrovimab (previously VIR-7831) and VIR-7832.

For a period of four years beginning April 2020, the parties agreed to conduct certain research and development activities under mutually agreed 

development plans and associated budgets for each of the three programs, and under the oversight of a joint steering committee, or JSC. During such 
period, generally, subject to certain rights granted to WuXi Biologics under existing agreements between us and WuXi Biologics, the parties will have an 
exclusive research collaboration with respect to antibody products directed to SARS-CoV-2 or to any other coronavirus, and in connection with 

37

 
 
  
functional genomics CRISPR screens for drug discovery and development in connection with SARS-CoV-2 or other coronaviruses. We are primarily 
responsible for the development and clinical manufacturing activities for the Antibody Program, and for conducting the initial development activities 
directed to a vaccine in the Vaccine Program. GSK is primarily responsible for the commercialization activities for the Antibody Program (except in 
connection with sales of antibody products licensed to WuXi Biologics in greater China), the later-stage development, manufacturing and 
commercialization activities for the Vaccine Program and the development, manufacturing and commercialization activities for the Functional Genomics 
Program. We and GSK are required to use commercially reasonable efforts to conduct the activities assigned to each party under each development plan 
and to seek and obtain regulatory approval for collaboration products that arise from such activities in the United States and specified major markets. 
Subject to an opt-out mechanism, we and GSK share all development costs, manufacturing costs and costs and expenses for the commercialization of the 
collaboration products, with us bearing 72.5% of such costs for the antibody products, 27.5% of such costs for the vaccine products, and we and GSK 
sharing equally all such costs for the functional genomics products, and all profits will be shared in the same ratios. If we and GSK elect to conduct a 
technology transfer of manufacturing technology under our agreement with WuXi Biologics (as further described below), we will bear 72.5% of the costs 
related to such manufacturing technology transfer and for commercial manufacturing of the antibody products under such agreement with WuXi Biologics, 
and GSK will bear 27.5% of such costs. The parties will also share the committed costs for the reservation of manufacturing capacity for the drug substance 
for antibody products in the foregoing ratio under our agreement with Samsung as well as such costs relating to committed manufacturing capacity for 
antibody products as are approved by the JSC from time to time.

On a collaboration product-by-collaboration product basis, each party has the one-time right, at specified points in development, to opt out of its co-
funding obligations, and the other party may, at its election, either pursue such program unilaterally, or also cease research and development activities and 
funding of such collaboration product. If the opt-out provisions are not exercised by either party subject to the terms of the 2020 GSK Agreement, the 
parties share all profits and losses arising from any collaboration product in the same ratios in which the parties bore development costs for such 
collaboration program. For each collaboration product as to which a party exercises its opt-out right, the commercializing party pays to the opt-out party 
royalties on net sales of the applicable collaboration product at rates based on factors such as the stage of development of such collaboration product at the 
time the opt-out party exercises such right, and whether the opt-out party is the lead party, or a portion of the sublicense revenue if the commercializing 
party chooses to sublicense or otherwise divest rights to such collaboration product. On an antibody product-by-antibody product basis, we have a co-
promotion right for such antibody product in the United States, under which we have the right to perform up to 20% of details in connection with such 
antibody product. GSK will lead commercialization and book all sales and is required to use commercially reasonable efforts to commercialize each 
collaboration product following regulatory approval in the United States and specified major markets. This definitive agreement superseded and replaced 
the April 2020 preliminary agreement with GSK. In connection with the 2020 GSK Agreement, we also entered into a stock purchase agreement in April 
2020, pursuant to which we issued 6,626,027 shares of our common stock to Glaxo Group Limited, or GGL, an affiliate of GSK, at a price per share of 
$37.73, for an aggregate purchase price of approximately $250.0 million.

The 2020 GSK Agreement will remain in effect with respect to each collaboration program for as long as there is a collaboration product being 

developed or commercialized by the lead party, or the non-opt-out party, in such program. Either party has the right to terminate the 2020 GSK Agreement 
in the case of the insolvency of the other party, an uncured material breach of the other party with respect to a collaboration program or collaboration 
product, or as mutually agreed by the parties. 

In December 2021, Beecham S.A. assigned and transferred all its rights, title, interest, and benefit in the 2020 GSK Agreement to GlaxoSmithKline 

Biologicals S.A., including all its rights to bring claims under such agreement. 

2021 Expanded GSK Collaboration 

In May 2021, we entered into the 2021 GSK Agreement under which the parties agreed to expand the 2020 GSK Agreement, to include 

collaboration on three separate programs: (1) a program to research, develop and commercialize mAbs for the prevention, treatment or prophylaxis of the 
influenza virus, or the Influenza Program, excluding VIR-2482 unless GSK exercises its option as described below; (2) an expansion of the parties' current 
Functional Genomics Program to focus on functional genomics screens directed to targets associated with respiratory viruses, or the Expanded Functional 
Genomics Program; and (3) additional programs to develop neutralizing mAbs directed to up to three non-influenza target pathogens selected by GSK, or 
the Selected Pathogens, and such programs, or the Additional Programs. Under the Influenza Program, we will collaborate to research, develop and 
commercialize our next generation mAbs for the prevention, treatment or prophylaxis of influenza. In addition, after we complete and report the Phase 2 
clinical trial outcomes for VIR-2482, GSK has the exclusive option to obtain exclusive rights to co-develop and commercialize VIR-2482, or the Option.

38

 
 
In connection with the 2021 GSK Agreement, we entered into a stock purchase agreement with GGL pursuant to which we issued 1,924,927 shares 

of our common stock to GGL for an aggregate purchase price of approximately $120.0 million. The 2021 GSK Agreement superseded and replaced the 
preliminary agreement entered into with GSK in February 2021, or the 2021 Preliminary Agreement. 

For a period of three years following the effective date of the 2021 GSK Agreement, or the Research Term, the parties will conduct certain research 
and development activities under mutually agreed development plans and associated budgets for the programs within the expanded collaboration. Subject 
to certain exceptions, we will exclusively collaborate with respect to (a) all of our mAbs that the parties agree to develop for the prevention, treatment or 
prophylaxis of the influenza virus, until such time there are none of our mAbs being developed under the expanded collaboration, (b) functional genomic 
screens for targets associated with respiratory viruses during the Research Term, and compounds or products developed through the Expanded Functional 
Genomics Program directed to a collaboration target for five years following the target selection (unless either party elects to opt-out earlier), and (c) 
products directed to Selected Pathogens during the Research Term. We will be responsible for continuing the development and clinical manufacturing 
activities for VIR-2482 unless and until GSK exercises the Option. If GSK does not exercise the Option for VIR-2482, then, in general, we have the right 
to continue the development and/or commercialization of VIR-2482 by itself or with a third party. GSK will be the lead party for development, clinical and 
commercial manufacturing, and commercialization activities for products under the Influenza Program (other than VIR-2482 unless and until GSK 
exercises the Option, if applicable). We will mutually agree upon the allocation of responsibility for the development of products under the Expanded 
Functional Genomics Program, and for the development and early-stage manufacturing of products under the Additional Programs if and when GSK 
decides which Selected Pathogens to pursue. GSK will be primarily responsible for commercial manufacturing and commercialization activities for 
products under the Expanded Functional Genomics Program and Additional Programs, if and when selected by GSK. For each collaboration program, upon 
execution of the definitive agreement, we will grant GSK certain license rights related to the development, manufacturing and commercialization of 
products arising from the program.

The parties will share 50% of all development costs in accordance with the budget for each of the collaboration programs (other than for the 
Selected Pathogens and VIR-2482, unless GSK exercises the Option), with each party having the right (on a target-by-target, or collaboration product-by-
collaboration product basis, as applicable) to opt-out of its co-funding obligations at specified points in development. In such case, the party continuing 
with the program will pay to the opt-out party a royalty on net sales of products arising from such program at specified rates based on the stage of 
development at which the opt-out is exercised. Following the exercise of an opt-out right by a party the other party may, at its election, either pursue 
development and commercialization of such product or program unilaterally, or also cease the conduct and funding of such collaboration product or 
program. In the absence of any opt-out, the parties will also share 50% of all profits and losses arising from any collaboration product. Each party is 
required to use commercially reasonable efforts to conduct the activities assigned to it under each development plan and, where applicable, to seek and 
obtain regulatory approval for collaboration products that arise from such activities in the United States and specified major markets. GSK will lead 
commercialization and book all sales, and is required to use commercially reasonable efforts to commercialize each collaboration product following 
regulatory approval in the United States and specified major markets.

GSK made an upfront payment to us of $225.0 million, 50% became payable at the effective date of the 2021 Preliminary Agreement and 50% of 

became payable following the execution of the 2021 GSK Agreement. If GSK exercises the Option, GSK will pay us an Option exercise fee of $300.0 
million unless certain agreed product criteria for VIR-2482 are not met, in which case the parties will negotiate an alternative option exercise fee. Upon 
achievement of a pre-defined regulatory milestone for the first product in the Influenza Program, which may be (i) VIR-2482 (if GSK exercised the 
Option), (ii) a next-generation mAb, or (iii) any other influenza mAb approved by the JSC to be included in the collaboration, arising from the Influenza 
Program, GSK will make a milestone payment to us of up to $200.0 million. 

With respect to the Influenza Program and each Additional Program, unless earlier terminated, the 2021 GSK Agreement will remain in effect for as 

long as there is a product from such collaboration program being developed or commercialized by the lead party in the collaboration program or by the 
non-opt-out party, if applicable. With respect to the Expanded Functional Genomics Program, unless earlier terminated, the 2021 GSK Agreement will 
remain in effect (a) until the end of the Research Term, if no targets are selected for the Expanded Functional Genomics Program prior to the end of the 
Research Term, or (b) if at least one target is selected for the Expanded Functional Genomics Program prior to the end of the Research Term, for as long as 
there is a product from the Expanded Functional Genomics Program being developed or commercialized by the lead party in the Expanded Functional 
Genomics Program or by the non-opt-out party, if applicable. Either party has the right to terminate the 2021 GSK Agreement in the case of the insolvency 
of the other party, an uncured material breach of the other party with respect to a collaboration program or a collaboration product, or as mutually agreed by 
the parties.

Collaboration and License Agreement with Alnylam 

In October 2017, we entered into a collaboration and license agreement with Alnylam, or the Alnylam Agreement, for the development of siRNA 

products for the treatment of HBV and following the exercise of certain program options, the development and commercialization of siRNA products 
directed to up to four other infectious disease targets selected by us. The technology licensed under the Alnylam Agreement forms the basis of our siRNA 
technology platform. 

Pursuant to the Alnylam Agreement, we obtained a worldwide, exclusive license to develop, manufacture and commercialize the HBV siRNA 

product candidates, including VIR-2218, for all uses and purposes other than agricultural, horticultural, forestry, aquaculture and other residential 
applications, such excluded fields, the Excluded Fields. In addition, Alnylam granted us an exclusive option, for each of the infectious disease siRNA 
programs directed to our selected targets, to obtain a worldwide, exclusive license to develop, manufacture and commercialize siRNA products directed to 
the target of each such program for all uses and purposes other than the Excluded Fields. Our options are each exercisable during a specified period 
following selection of candidates for each program, or two years following the initiation of certain activities under an agreed-upon development plan, if 
earlier. On a product-by-product basis for each product arising from the HBV and, following our option exercise, the infectious disease programs, Alnylam 
has an exclusive option, exercisable during a specified period prior to the initiation of a Phase 3 clinical trial for each such product, to negotiate and enter 
into a profit-sharing agreement for such product. 

We and Alnylam are jointly responsible for funding the initial research and development activities for VIR-2218 through completion of proof of 

concept trials. Prior to the exercise of our option for each siRNA program directed to one of our selected infectious disease targets, Alnylam is responsible 
for conducting all development activities, at our expense, in accordance with an agreed-upon development plan. Following our exercise of an option for a 
program and payment of the program option exercise fee and any outstanding program costs due to Alnylam, we are solely responsible, at our expense, for 
conducting all development, manufacture and commercialization activities for products arising from each such program unless Alnylam exercises its profit-
sharing option. We are required to use commercially reasonable efforts to develop and commercialize one siRNA product directed to HBV and one siRNA 
product directed to the target of each other infectious disease program for which we exercise our option, in each of the major markets. If Alnylam exercises 
a profit-sharing option for a product, we will negotiate the terms of such profit-sharing agreement, which will include sharing equally with Alnylam all 
subsequent costs associated with the development of such product, as well as the profits and losses in connection with such product, subject to 
reimbursement by Alnylam of a portion of specified development costs in certain circumstances. 

We retain final decision-making authority with respect to which infectious disease product candidates we advance and the development programs for 
the HBV and infectious disease product candidates, subject to certain limitations. During the term of the Alnylam Agreement, neither we nor Alnylam may 
develop or commercialize any gene-silencing, oligonucleotide-based product directed to the same target as any product candidate under the Alnylam 
Agreement, other than pursuant to the Alnylam Agreement, subject to certain exceptions. 

40

 
Pursuant to the Alnylam Agreement, we paid Alnylam an upfront fee of $10.0 million and issued to Alnylam 1,111,111 shares of our common stock. 
Upon the achievement of a certain development milestone, as further discussed below, we were obligated to issue shares of our common stock equal to the 
lesser of (i) 1,111,111 shares or (ii) a certain number of shares based on our stock price at the time such milestone was achieved. We will be required to pay 
Alnylam up to $190.0 million in the aggregate for the achievement of specified development and regulatory milestones by the first siRNA product directed 
to HBV, and up to $115.0 million for the achievement of specified development and regulatory milestones for the first product directed to the target of each 
infectious disease siRNA program for which we exercised our option. Following commercialization, we will be required to pay to Alnylam up to $250.0 
million in the aggregate for the achievement of specified levels of net sales by siRNA products directed to HBV and up to $100.0 million for the 
achievement of specified levels of net sales by products directed to the target of each infectious disease siRNA program for which we exercised our option. 
We will also be required to pay Alnylam tiered royalties at percentages ranging from the low double-digits to mid-teens on annual net sales of HBV 
products, and tiered royalties at percentages ranging from the high single-digits to the sub-teen double-digits on annual net sales of licensed infectious 
disease products, in each case subject to specified reductions and offsets. The royalties are payable on a product-by-product and country-by-country basis 
until the later of the expiration of all valid claims of specified patents covering such product in such country and 10 years after the first commercial sale of 
such product in such country. Alnylam is also entitled to receive a portion of any consideration we receive as a result of granting a sublicense under the 
licenses granted to us by Alnylam under the Alnylam Agreement or an option to acquire such a sublicense, determined based on the timing of the grant of 
such sublicense. In November 2018, in connection with the inclusion of the HBV siRNA program as the subject of a potential grant of a sublicense to Brii 
Bio under the Brii Agreement, as defined under the section titled “—Collaboration, Option and License Agreement with Brii Bio,” which triggered certain 
payment obligations under the Alnylam Agreement, we entered into a letter agreement with Alnylam, or the Alnylam Letter, making certain modifications 
to the payments due to Alnylam as a result of the grant of the option and potential payments that would result from Brii Bio’s exercise of rights under such 
sublicense. As a result of the rights granted under the Brii Agreement and pursuant to the Alnylam Letter, in February 2020 we transferred to Alnylam a 
specified percentage of the equity consideration allocable to the HBV siRNA program that we received from Brii Bio and its affiliated companies in 
connection with the entry into the Brii Agreement. 

The term of the Alnylam Agreement will continue, on a product-by-product and country-by-country basis, until expiration of all royalty payment 
obligations under the Alnylam Agreement. If we do not exercise our option for an infectious disease program directed to one of our selected targets, the 
Alnylam Agreement will expire upon the expiration of the applicable option period with respect to such program. However, if Alnylam exercises its profit-
sharing option for any product, the term of the Alnylam Agreement will continue until the expiration of the profit-sharing arrangement for such product. 
We may terminate the Alnylam Agreement on a program-by-program basis or in its entirety for any reason on 90 days’ written notice. Either party may 
terminate the agreement for cause for the other party’s uncured material breach on 60 days’ written notice (or 30 days’ notice for payment breach), or if the 
other party challenges the validity or enforceability of any patent licensed to it under the Alnylam Agreement on 30 days’ notice. 

In March 2020, we achieved one of the specified development milestones relating to VIR-2218 pursuant to the Alnylam Agreement, as amended. As 

such, we paid Alnylam $15.0 million in April 2020, and issued Alnylam 1,111,111 shares of our common stock in May 2020. 

In March and April 2020, we entered into two further amendments to the Alnylam Agreement, or the Amended Alnylam Agreement, to expand our 

existing collaboration to include the development and commercialization of siRNA products targeting SARS-CoV-2 and potentially other coronaviruses, 
and up to three targeting human host factors for SARS-CoV-2, or collectively, the COVID Collaboration Targets. 

In December 2020, we and Alnylam entered into a letter amendment, or the Letter Agreement, further amending the Amended Alnylam Agreement 
to modify certain funding and governance provisions in connection with the siRNA products directed to the COVID Collaboration Targets, including VIR-
2703, or the COV Target, and to modify certain rights of each party with respect to products arising from such programs. Pursuant to the Letter Agreement, 
Alnylam was responsible for conducting pre-clinical research activities set forth in the existing workplan for the COV Target, or the COV Workplan, at its 
discretion and sole expense, and we were no longer obligated to reimburse Alnylam for any share of costs incurred by Alnylam in conducting activities 
under the COV Workplan after July 1, 2020. In July 2021, Alnylam elected to discontinue the development of the COV Target, and all other related 
research and development activities in accordance with their rights under the Letter Agreement. As a result, the COV Target and the siRNA program 
related thereto are no longer included within the Amended Alnylam Agreement and all rights to the siRNA program directed to the COV Target reverted to 
Alnylam.

License Agreements with MedImmune 

2012 Sub-License and Collaboration Agreement with MedImmune 

In March 2012, our subsidiary Humabs entered into a sub-license and collaboration agreement with MedImmune, LLC, or MedImmune, as 

amended, or the 2012 MedImmune Agreement, pursuant to which Humabs conducted certain activities under a mutually agreed research plan for the 
development of therapeutic antibodies directed to influenza viruses (including influenza A and influenza B) and to Klebsiella bacteria. The 2012 
MedImmune Agreement was amended in April 2013, April 2015, December 2015, August 2016, July 2017, and September 2018 to designate Klebsiella as 
an extra target, to extend the term of the research program and provide for related payments, and to incorporate certain research activities funded by 
MedImmune under a specified government grant. Under the 2012 MedImmune Agreement, as amended, MedImmune obtained a worldwide exclusive 
license from Humabs to develop and commercialize products directed to such targets for all uses in humans and animals except for active vaccination. 
MedImmune is obligated to use commercially reasonable efforts to develop at least one product directed to influenza viruses. 

In consideration for the grant of the license, MedImmune made certain upfront payments to Humabs. MedImmune is obligated to pay Humabs 

development, regulatory and commercial milestone payments of up to $96.5 million in the aggregate for the first product directed to influenza viruses to 
achieve the applicable milestones, and up to $12.0 million for the first product directed to Klebsiella to achieve the applicable milestones. MedImmune will 
also be obligated to pay royalties based on net sales of products directed to influenza viruses or Klebsiella at certain fixed percentages in the low to mid-
single-digits, with the rate determined based on the specific target to which the product is directed, in each case subject to specified reductions and a royalty 
floor. The royalties are payable, on a product-by-product and country-by-country basis, until the later of the last to expire valid claim that would, but for the 
licenses granted under the 2012 MedImmune Agreement, be infringed by the sale of such product in such country, and 10 years from the first commercial 
sale of the first product in such country. MedImmune also made certain payments to Humabs in consideration for Humabs’ conduct of the research 
program. We will be obligated to pass through the milestone payments and royalty payments that we receive under the 2012 MedImmune Agreement, 
following deduction of certain expenses incurred by us or Humabs thereunder, to Humabs’ securities holders pursuant to the Humabs SPA, as defined under 
the section titled “—Securities Purchase Agreement with Humabs.” 

The 2012 MedImmune Agreement will remain in force until MedImmune has fulfilled all of its obligations to make milestone and royalty payments. 

MedImmune may terminate the 2012 MedImmune Agreement in its entirety, or on a product-by-product, license-by-license or country-by-country basis, 
for convenience, upon 90 days’ notice. Either MedImmune or Humabs may terminate the 2012 MedImmune Agreement for the other party’s uncured 
material breach or in the event of bankruptcy of the other party. 

42

 
2018 License Agreement with MedImmune 

In September 2018, we entered into a license agreement with MedImmune, or the 2018 MedImmune Agreement, pursuant to which we obtained a 

worldwide, exclusive license to develop and commercialize half-life extended versions of two specified antibodies under development by MedImmune that 
target influenza A and influenza B, respectively, for all uses in humans and animals. The license from MedImmune includes the grant of a sublicense under 
MedImmune’s license to certain intellectual property controlled by Humabs that was granted to MedImmune pursuant to the 2012 MedImmune Agreement. 
Under certain circumstances and during certain periods of time we have the right to nominate up to two variants of each of these antibodies for inclusion 
under the license. MedImmune retained the rights to continue to develop and to commercialize the two specified antibodies that target influenza A and 
influenza B, in each case that are not the half-life extended versions that are licensed to us. Additionally, we obtained a worldwide, exclusive license under 
MedImmune’s antibody half-life extension technology to develop and commercialize half-life extended antibodies directed to up to two additional targets 
selected by us for all uses in humans or animals for the prevention, treatment or diagnosis of infectious diseases. We have the right to nominate such 
additional targets during a specified period following the effective date of the 2018 MedImmune Agreement. In September 2020, the 2018 MedImmune 
Agreement was amended to adjust the period of time we have the right to nominate up to two antibodies for inclusion under the MedImmune’s antibody 
half-life extension technology license. MedImmune may only refuse our nomination if such targets are already the subject of internal development by 
MedImmune, are subject to third party rights at the time of our selection, or are the subject of good faith discussions between MedImmune and a third party 
for a license for products directed to such targets. We are solely responsible, at our sole cost, for the development of products containing half-life extended 
versions of antibodies directed to the influenza targets and any additional selected targets, and are obligated to use commercially reasonable efforts to 
develop and obtain regulatory approval for at least one product containing half-life extended versions of antibodies directed to each of influenza A, 
influenza B and any additional targets, if applicable, in the United States and specified markets in Europe and Asia. We are also obligated to use 
commercially reasonable efforts to commercialize products containing half-life extended versions of antibodies directed to such targets in such markets. We 
are developing VIR-2482 using technology licensed under the 2018 MedImmune Agreement. 

In consideration for the grant of the licenses under the 2018 MedImmune Agreement, we made an upfront payment to MedImmune of $10.0 million. 
We will be obligated to make development and regulatory milestone payments to MedImmune of up to $92.0 million, of which $5.0 million was paid in the 
third quarter of 2019, in the aggregate for products containing half-life extended versions of antibodies directed to influenza A that we licensed, up to an 
additional $39.2 million in the aggregate for such products directed to influenza B that we licensed, and up to $250,000 in the aggregate for certain 
specified products directed to the additional selected targets, if applicable. We will also be required to make sales-related milestone payments to 
MedImmune following commercialization up to an aggregate of $200.0 million for the achievement of specified levels of aggregate annual net sales of 
products containing half-life extended versions of antibodies directed to influenza A and/or influenza B. MedImmune will also be entitled to receive tiered 
royalties based on net sales of products containing half-life extended versions of antibodies directed to influenza A and/or influenza B at percentages 
ranging from the mid-single-digits to sub-teen double-digits and a royalty based on net sales of products containing half-life extended versions of 
antibodies directed to any additional selected targets, if applicable, at a percentage in the low single-digits, in each case subject to specified reductions. 
These royalties are payable, on a product-by-product and country-by-country basis, until the latest to occur of expiration of the last to expire valid claim 
covering such product in such country, expiration of regulatory exclusivity for such product in such country, and 12 years after the first commercial sale of 
such product in such country. Additionally, we are responsible for paying any royalties due under the 2012 MedImmune Agreement as a result of our 
commercialization of products under the 2018 MedImmune Agreement. 

The 2018 MedImmune Agreement will remain in force until the expiration on a country-by-country and product-by-product basis of all of our 
obligations to pay royalties to MedImmune. We may terminate the 2018 MedImmune Agreement in its entirety or on a product-by-product basis, for 
convenience, upon 120 days’ notice. Either party may terminate the 2018 MedImmune Agreement for cause for the other party’s uncured material breach 
on 60 days’ notice or immediately in the event of bankruptcy of the other party. Additionally, MedImmune may terminate the 2018 MedImmune 
Agreement for cause on 30 days’ written notice if we challenge the validity or enforceability of the patents to which we have obtained a license under the 
2018 MedImmune Agreement. 

Master Exclusive License Agreement with OHSU 

In June 2012, our subsidiary TomegaVax, Inc., or TomegaVax, entered into a master exclusive license agreement, or the OHSU Agreement, with 

Oregon Health & Science University, or OHSU. The OHSU Agreement was revised and restated in August 2014 and again in August 2019, at which time 
we assumed TomegaVax’s rights and obligations as licensee under the OHSU Agreement. Under the OHSU Agreement, we obtained a worldwide exclusive 
license under certain patent rights 

43

 
  
and a non-exclusive license under certain know-how to make, have made, use, offer to sell, sell, have sold, export and import certain products relating to 
CMV vectors in all fields of use. The OHSU Agreement provides for us to include within the license grant additional patent or know-how rights covering 
certain inventions arising at OHSU and relating to the use of CMV vaccine vectors through the execution of technology addenda, each such addendum, a 
Technology Addendum. Each Technology Addendum relates to a single invention disclosure and family of patent or know-how rights. During the term of 
the OHSU Agreement to date, we have entered into 17 such Technology Addenda. We must use reasonably diligent efforts to develop and commercialize 
the CMV vector products consistent with its reasonable business practices and judgment, including by achieving certain specified development and 
regulatory milestones within certain periods. We use technology licensed under the OHSU Agreement in our T cell platform and in our product candidate 
VIR-1111. 

Pursuant to the initial entry into the OHSU Agreement and certain of the Technology Addenda, TomegaVax issued a specified percentage of its then 

outstanding common stock to OHSU, which was subsequently exchanged for shares of our common stock as a result of our acquisition of TomegaVax in 
September 2016. In connection with the second revision and restatement of the OHSU Agreement in August 2019, we issued an additional specified 
number of shares of our common stock to OHSU. We are obligated to pay OHSU up to $1.3 million upon the achievement of certain development and 
regulatory milestones for each CMV vector product, and up to $2.0 million upon the achievement of certain aggregate annual net sales milestones for all 
CMV vector products. We will also be required to pay OHSU a royalty in the low single-digits on net sales of licensed products on a product-by-product 
basis, subject to specified reductions and offsets, and specified minimum annual royalty payments. The royalties are payable, on a product-by-product and 
country-by-country basis, until the later of (a) the expiration of all valid claims in the licensed patents covering such product in the country of sale or 
country of manufacture, as applicable, and (b) 10 years after the first commercial sale of such product in the country of sale. OHSU is also entitled to 
receive a specified percentage of any consideration received by us as a result of the grant of a sublicense under the rights granted under the OHSU 
Agreement, with the applicable percentage based on the development stage of the applicable program at the time of the grant of the sublicense. 

The OHSU Agreement will remain in force until the expiration of all licensed patent rights or 10 years after the effective date of the last Technology 

Addendum, whichever is the later. Each individual Technology Addendum remains in force until the expiration of the patent rights to which it applies, or 
10 years after the effective date of such Technology Addendum, whichever is later. Either party may terminate the OHSU Agreement, or any individual 
Technology Addendum, for the other party’s uncured material breach on 60 days’ written notice, which may be extended by an additional 120 days under 
certain conditions. The OHSU Agreement and each Technology Addendum also terminate in the event of bankruptcy of either party. We may also 
terminate the OHSU Agreement in its entirety, or any Technology Addendum individually, upon 60 days’ notice. OHSU may immediately terminate the 
OHSU Agreement if we or our sublicensees bring any action or proceeding against OHSU, subject to certain exceptions. 

Exclusive License Agreement with the Institute for Research in Biomedicine 

In December 2011, Humabs Holdings GmbH, or Humabs Holdings, the former parent company of our subsidiary Humabs, entered into an exclusive 

license agreement, or the IRB Agreement, with the Institute for Research in Biomedicine, or IRB. The IRB Agreement amended and restated an original 
2004 exclusive license agreement between the parties in connection with IRB’s proprietary technologies relating to human monoclonal antibodies and the 
discovery of unique epitopes recognized by such antibodies. In May 2008, Humabs entered into an exclusive license agreement with IRB, or the Humabs 
IRB Agreement, and together with the IRB Agreement, the Current IRB License Agreements. Pursuant to the Humabs IRB Agreement, IRB granted to 
Humabs an exclusive license under certain intellectual property rights for the development of certain monoclonal antibodies. Following the entry into the 
Humabs IRB Agreement, in February 2012, Humabs and IRB entered into a research agreement, or the IRB Research Agreement, concurrently with the 
termination of an original research agreement dated July 2004 between Humabs Holdings and IRB, to provide for a continuing research collaboration 
between Humabs and IRB, and to coordinate the exploitation of intellectual property rights arising from the IRB Research Agreement with the rights 
granted under the Current IRB License Agreements. Under the terms of the IRB Research Agreement, IRB performs certain research activities for Humabs, 
and all intellectual property rights arising under the IRB Research Agreement are either owned by Humabs, or included in and licensed to Humabs pursuant 
to the terms of the Current IRB License Agreements. In August 2017, we acquired all of the share capital of Humabs as described further below. Prior to 
the closing of such acquisition, Humabs Holdings was consolidated into Humabs, such that Humabs Holdings ceased to exist as a separate legal entity, and 
Humabs became the successor-in-interest to Humabs Holdings’ rights under the IRB Agreement. As a result, Humabs is the licensee under each of the 
Current IRB License Agreements. 

We use technology licensed under the Current IRB License Agreements in our antibody platform and in our product candidates VIR-2482 and VIR-

3434. 

44

 
Pursuant to the Current IRB License Agreements, IRB granted to Humabs an exclusive, worldwide, royalty-bearing, sublicensable license under 

patent and know-how rights covering or associated with IRB’s proprietary technology platform relating to antibody discovery, as well as rights in certain 
antibodies, including as a result of activities under the IRB Research Agreement, in each case for all purposes, including to practice the licensed technology 
platform, and to develop, manufacture and commercialize any drug, vaccine or diagnostic product containing such licensed antibodies. Humabs is required 
to use commercially reasonable efforts to develop and commercialize licensed products, and must maintain an active program to commercialize licensed 
products. Humabs is required to pay to IRB a flat royalty on net sales of licensed products approved for non-diagnostic use in the low single-digits, and a 
flat royalty on licensed products for diagnostic use at 50% of the non-diagnostic product rate, in each case subject to standard reductions and offsets. A 
single royalty stream is payable on products that include the licensed antibodies (including antibodies that are owned by Humabs, but developed using the 
licensed technology), irrespective of whether a given product is covered by patents under both of the Current IRB License Agreements. Humabs’ obligation 
to pay royalties to IRB, on a country-by-country basis, is reduced upon the expiration of the relevant patents in such country, and expires 10 years after the 
date of first commercialization of a licensed product in such country. Humabs is also required to pay to IRB a specified percentage in the sub-teen double-
digits of consideration received in connection with the grant of a sublicense to a non-affiliate third party, subject to a specified maximum dollar amount for 
the first up front or milestone payment received under such sublicense for each licensed product, and a lower specified maximum dollar amount for 
subsequent up front or milestone payments for such licensed product. 

Each of the Current IRB License Agreements remains in force until the expiration of all valid claims of the licensed patent rights and trade secrets 

included in the licensed IRB know-how. Humabs may terminate the IRB Agreement at will on 90 days’ written notice to IRB, and either party may 
terminate either of the Current IRB License Agreements on 60 days’ written notice for the uncured material breach of the other party. 

Exclusive License Agreement with The Rockefeller University 

In July 2018, we entered into an exclusive license agreement with The Rockefeller University, or Rockefeller, which was amended in May 2019, in 
September 2020, and in March 2021, or the Rockefeller Agreement. Pursuant to the Rockefeller Agreement, Rockefeller granted us a worldwide exclusive 
license under certain patent rights, and a worldwide non-exclusive license under certain materials and know-how covering certain antibody variants relating 
to a specified mutation leading to enhanced antibody function and utility, to develop, manufacture and commercialize infectious disease products covered 
by the licensed patents, or that involve the use or incorporation of the licensed materials and know-how, in each case for all uses and purposes for infectious 
diseases. The licenses granted to us are freely sublicensable to third parties. Rockefeller retains the right to use the licensed patents outside the field of use, 
and within the field of use solely in connection with educational, research and non-commercial purposes, as well as for certain research being conducted in 
collaboration with us. We are obligated to grant sublicenses to third parties with respect to products that are not being pursued and are not of interest to us 
following a specified anniversary of the May 2019 amendment date. Pursuant to the Rockefeller Agreement, we are required to use commercially 
reasonable efforts to develop and commercialize infectious disease products as soon as reasonably practicable, including by achieving certain specified 
development milestone events within specified time periods for products arising from our HBV and influenza programs. 

We use technology licensed under the Rockefeller Agreement in our antibody platform and in our product candidates VIR-3434 and VIR-7832. 

We paid Rockefeller an upfront fee of $0.3 million for entry into the Rockefeller Agreement, and are required to pay annual license maintenance 
fees of $1.0 million, which will be creditable against royalties following commercialization. In addition, for the achievement of specified development, 
regulatory and commercial success milestone events, we will be required to pay up to $80.3 million, in the aggregate, for up to six infectious disease 
products. Any follow-on products beyond six products may result in additional milestone event payments. We will also be required to pay to Rockefeller a 
tiered royalty at a low single-digit percentage rate on net sales of licensed products, subject to certain adjustments. Our obligation to pay royalties to 
Rockefeller will terminate, on a product-by-product and jurisdiction-by-jurisdiction basis, upon the latest of the expiration of the last valid claim of a 
licensed patent in such jurisdiction, the expiration of all regulatory exclusivity in such jurisdiction or 12 years following the first commercial sale of the 
applicable licensed product in such jurisdiction. If we grant a sublicense to a non-affiliate third party under the Rockefeller technology, we will be required 
to pay to Rockefeller a specified percentage of the consideration received from such sublicensee for the grant of the sublicense, depending on the date of 
receipt of the applicable sublicense income from such sublicensee. 

The Rockefeller Agreement will remain in force, absent earlier termination, until the expiration of all of our obligations to pay royalties to 

Rockefeller in all jurisdictions. We have the right to terminate the Rockefeller Agreement in its entirety, or 

45

 
in part, for any reason on 60 days’ written notice to Rockefeller. Rockefeller may terminate the Rockefeller Agreement on 90 days’ written notice for our 
uncured material breach, or if we challenge the validity or enforceability of any of the licensed patents, or immediately in the event of our insolvency. 
Rockefeller may also terminate the Rockefeller Agreement if we cease to carry on business with respect to the rights granted to us under the agreement. 

Collaboration, Option and License Agreement with Brii Bio 

In May 2018, we entered into a collaboration, option and license agreement with Brii Biosciences Limited (previously named BiiG Therapeutics 

Limited), or Brii Bio Parent, and Brii Bio, and such agreement, the Brii Agreement, pursuant to which we granted to Brii Bio, with respect to up to four of 
our programs (excluding mAbs in Vir’s active research and development program against coronaviruses), an exclusive option to obtain exclusive rights to 
develop and commercialize compounds and products arising from such programs in China, Taiwan, Hong Kong and Macau, or collectively the China 
Territory, for the treatment, palliation, diagnosis, prevention or cure of acute and chronic diseases of infectious pathogen origin or hosted by pathogen 
infection, or the Field of Use. Our HBV siRNA program being developed under the Amended Alnylam Agreement (described above) is included within the 
Brii Agreement as a program for which Brii Bio may exercise one of its options. Brii Bio may exercise each of its options following the achievement by us 
of proof of concept for the first product in such program. In partial consideration for the options granted by us to Brii Bio, Brii Bio Parent and Brii Bio 
granted us, with respect to up to four of Brii Bio Parent’s or Brii Bio’s programs, an exclusive option to be granted exclusive rights to develop and 
commercialize compounds and products arising from such Brii Bio programs in the United States for the Field of Use. The number of options that we may 
exercise for a Brii Bio program is limited to the corresponding number of options that Brii Bio exercises for a Vir program. All options granted to Brii Bio 
under the Brii Agreement that are not exercised will expire no later than seven years following the effective date, or two years earlier than such date if Brii 
Bio has not undergone an initial public offering within such shorter period. All options granted to us under the Brii Agreement that are not exercised will 
expire no later than two years following the expiration of all options granted to Brii Bio. 

We are responsible, at our expense and discretion, for the conduct of all development activities under our programs prior to the exercise of Brii Bio’s 

options, and Brii Bio is responsible, at its expense and discretion, for all activities under its programs prior to the exercise of our options. Following the 
exercise of an option for a specified program by either us or Brii Bio, the exercising party is granted an exclusive, royalty-bearing license to develop, 
manufacture and commercialize products arising from the applicable program in the United States (where we are exercising the option) or the China 
Territory (where Brii Bio is exercising the option), and such party is thereafter responsible for all development and commercialization activities, at its 
expense, in the optioned territory. If Brii Bio exercises its option with respect to our development program being conducted under the Amended Alnylam 
Agreement, Brii Bio’s rights will be subject to the terms of such amended agreement. 

Under the terms of the Brii Agreement, following our option exercise, we are obligated to use commercially reasonable efforts to develop at least 

one licensed product arising from each optioned Brii Bio program, and to commercialize each such product in the United States following regulatory 
approval, and following Brii Bio’s option exercise, Brii Bio is obligated to use commercially reasonable efforts to develop at least one licensed product 
arising from each optioned Vir program and to commercialize each such product in the China Territory following regulatory approval. 

With respect to programs for which Brii Bio exercises its options, Brii Bio will be required to pay us an option exercise fee for each such Vir 

program ranging from the mid-single-digit millions up to $20.0 million, determined based on the commercial potential of the licensed program. Brii Bio 
will also be required to pay regulatory milestone payments on a licensed product-by-licensed product basis ranging from the mid-single-digit millions up to 
$30.0 million, also determined based on the commercial potential of such program. Following commercialization, Brii Bio will be required to make sales 
milestone payments based on certain specified levels of aggregate annual net sales of products arising from each licensed program in the China Territory, 
up to an aggregate of $175.0 million per licensed program. Brii Bio also will pay us royalties that range from the mid-teens to the high-twenties, as 
described below. On June 12, 2020, Brii Bio notified us of the exercise of its option to obtain exclusive rights to develop and commercialize compounds 
and products arising from VIR-2218 in the China Territory. Brii Bio paid us a $20.0 million option exercise fee in connection with the option exercise. We 
separately paid $10.0 million, half of the option proceeds, to Alnylam in connection with the Amended Alnylam Agreement.

As partial consideration for our entry into the Brii Agreement, upon closing of Brii Bio Parent’s Series A preferred stock financing, we received 

Class A ordinary shares equal to 9.9% of the outstanding shares in Brii Bio Parent. As a result of Brii Bio’s right to exercise one of its options for our HBV 
siRNA program, under the terms of the Amended Alnylam Agreement, in February 2020 we transferred to Alnylam a specified percentage of such equity 
consideration allocable to such program. In July 2021, Brii Bio Parent completed its initial public offering, or the Brii Bio Parent IPO, on the Stock 

46

 
Exchange of Hong Kong Limited. Upon completion of the Brii Bio Parent IPO, our Class A ordinary shares held at Brii Bio Parent converted into the same 
single class of ordinary shares issued in the Brii Bio Parent IPO. 

Upon exercise of each option for a Brii Bio program, we will be required to pay to Brii Bio an option exercise fee ranging from the low tens of 

millions to up to $50.0 million, determined based on the commercial potential of the licensed program. We will be required to make regulatory milestone 
payments to Brii Bio on a licensed product-by-licensed product basis ranging from the low tens of millions up to $100.0 million, also determined based on 
the commercial potential of such program. We will also be required to make sales milestone payments based on certain specified levels of aggregate annual 
net sales of products in the United States arising from each licensed program, up to an aggregate of $175.0 million per licensed program. 

In addition, we are obligated under the Brii Agreement to pay Brii Bio tiered royalties based on net sales of products arising from the licensed 

programs in the United States, and Brii Bio is obligated to pay us tiered royalties based on net sales of products arising from the licensed programs in the 
China Territory. The rates of royalties payable by us to Brii Bio, and by Brii Bio to us on net sales range from mid-teens to high-twenties. Each party’s 
obligations to pay royalties expires, on a product-by-product and territory-by-territory basis, on the latest of 10 years after the first commercial sale of such 
licensed product in the United States or China Territory, as applicable; the expiration or abandonment of licensed patent rights that cover such product in 
the United States or China Territory, as applicable; and the expiration of regulatory exclusivity in the United States or the China Territory, as applicable. 
Royalty rates are subject to specified reductions and offsets. 

The Brii Agreement will remain in force until the expiration of all options or, if any option is exercised, expiration of all royalty payment obligations 

for all licensed products within such licensed program, unless terminated in its entirety or on a program-by-program basis by either party. Each party may 
terminate for convenience all rights and obligations with respect to any program for which it has an option, with 30 days’ written notice (if the terminating 
party has not exercised an option for such program) or 180 days’ notice (following the exercise of an option for such program). The Brii Agreement may 
also be terminated by either party for insolvency of the other party, and either party may terminate the Brii Agreement in its entirety or on a program-by-
program basis for the other party’s uncured material breach on 60 days’ written notice (or 30 days’ notice following failure to make payment). 

Patent License Agreements with Xencor 

In August 2019, we entered into a patent license agreement, which was amended in February 2021, or the 2019 Xencor Agreement, with Xencor, 

pursuant to which we obtained a non-exclusive, sublicensable (only to our affiliates and subcontractors) license to incorporate Xencor’s licensed 
technologies into, and to evaluate, antibodies that target influenza A and HBV, and a worldwide, non-exclusive, sublicensable license to develop and 
commercialize products containing such antibodies incorporating such technologies for all uses, including the treatment, palliation, diagnosis and 
prevention of human or animal diseases, disorders or conditions. We are obligated to use commercially reasonable efforts to develop and commercialize an 
antibody product that incorporates Xencor’s licensed technologies, for each of the influenza A and HBV research programs. These technologies are used in 
our VIR-2482, incorporating Xencor’s Xtend technology, and VIR-3434, incorporating Xencor’s Xtend and other Fc technologies.  

In consideration for the grant of the license, we paid Xencor an upfront fee. For each of the influenza A and HBV research programs, we will be 

required to pay Xencor development and regulatory milestone payments of up to $17.8 million in the aggregate, and commercial sales milestone payments 
of up to $60.0 million in the aggregate, for a total of up to $77.8 million in aggregate milestones for each program and $155.5 million in aggregate 
milestones for both programs. On a product-by-product basis, we will also be obligated to pay tiered royalties based on net sales of licensed products 
ranging from low- to mid-single-digits. The royalties are payable, on a product-by-product and country-by-country basis, until the expiration of the last to 
expire valid claim in the licensed patents covering such product in such country. 

In March 2020, we entered into a patent license agreement, which was amended in February 2021, or the 2020 Xencor Agreement, with Xencor 

pursuant to which we obtained a non-exclusive license to Xencor’s licensed technologies into, and to evaluate, antibodies that target any component of a 
coronavirus, including SARS-CoV-2, SARS-CoV and MERS-CoV, and a worldwide, non-exclusive, sublicensable license to develop and commercialize 
products containing such antibodies incorporating such technologies for all uses, including the treatment, palliation, diagnosis and prevention of human or 
animal diseases, disorders or conditions. We are obligated to use commercially reasonable efforts to develop and commercialize an antibody product that 
incorporates Xencor’s licensed technologies, for each of the coronavirus research programs. These technologies are used in sotrovimab, incorporating 
Xencor’s Xtend technology, and VIR-7832, incorporating Xencor’s Xtend and other Fc technologies. 

47

 
In consideration for the grant of the license, we are obligated to pay royalties based on net sales of licensed products at the mid-single-digits. The 

royalties are payable, on a product-by-product and country-by-country basis, until the later of the expiration of the last to expire valid claim in the licensed 
patents covering such product in such country or 12 years.

The 2019 Xencor Agreement and 2020 Xencor Agreement will remain in force, on a product-by-product and country-by-country basis, until the 

expiration of all royalty payment obligations under each of the respective agreements. We may terminate each agreement in its entirety, or on a target-by-
target basis, for convenience upon 60 days’ written notice. Either party may terminate each agreement for the other party’s uncured material breach upon 
60 days’ written notice (or 30 days in the case of non-payment) or in the event of bankruptcy of the other party immediately upon written notice. Xencor 
may terminate each agreement immediately upon written notice if we challenge, or upon 30 days’ written notice if any of our sublicensees challenge, the 
validity or enforceability of any patent licensed to us under each respective agreement.

Amended and Restated Letter Agreement with the Bill & Melinda Gates Foundation

In January 2022, we entered into an amended and restated letter agreement with the Bill & Melinda Gates Foundation, or the Gates Agreement, 

which amended and restated the letter agreement with the Bill & Melinda Gates Foundation that we entered into in December 2016. In connection with the 
Gates Agreement, the Bill & Melinda Gates Foundation purchased $10.0 million of shares of our Series A-1 convertible preferred stock in December 2016, 
$10.0 million of shares of our Series B convertible preferred stock in January 2019 and $40.0 million of shares of our common stock in January 2022. We 
were obligated to use the proceeds of the Bill & Melinda Gates Foundation’s December 2016 and January 2019 investments in furtherance of its charitable 
purposes to (i) conduct our programs to develop products to treat or prevent infectious disease caused by HIV and TB, respectively, with at least 50% of the 
funds to be used for such programs and (ii) develop our HCMV-based vaccine technology platform in a manner reasonably expected to result in the 
generation of products for the treatment or prevention of other specified infectious diseases, and we are obligated to use the proceeds of the Bill & Melinda 
Gates Foundation’s January 2022 investment in furtherance of its charitable purposes to develop our vaccinal antibody program, in each case for use in 
specified developing countries. We agreed to use reasonable efforts to achieve specified research and development milestones with respect to our HIV 
program, TB program and vaccinal antibody program, and, if requested by the Bill & Melinda Gates Foundation, to work with the Bill & Melinda Gates 
Foundation on an additional mutually agreeable infectious disease program. Additionally, we are bound by specified global access commitments including 
a commitment to provide any products developed using the proceeds of the Bill & Melinda Gates Foundation’s investment at an affordable price to the 
people most in need within the specified developing countries, not to exceed a specified percentage over our fully burdened manufacturing and sales costs.

If we fail to comply with (i) our obligations to use the proceeds of the Bill & Melinda Gates Foundation’s investment for the purposes described in 
the paragraph above and to not use such proceeds for specified prohibited uses, (ii) specified reporting requirements or (iii) specified applicable laws, or if 
we materially breach our specified global access commitments (any such failure or material breach, a Specified Default), we will be obligated to redeem or 
arrange for a third party to purchase all of our stock purchased by the Bill & Melinda Gates Foundation under the Gates Agreement at the Bill & Melinda 
Gates Foundation’s request, at a price equal to the greater of (a) the original purchase price or (b) the fair market value, such redemption or sale, a Gates 
Foundation Redemption. Following a Gates Foundation Redemption, if a sale of the company or all of our material assets relating to the Gates Agreement 
occurs prior to the six month anniversary of the first redemption or sale of any stock in such Gates Foundation Redemption, then the Bill & Melinda Gates 
Foundation will receive compensation equal to the excess of what it would have received in such transaction if it still held the stock redeemed or sold at the 
time of such sale transaction over what it actually received in the Gates Foundation Redemption. Additionally, if a specified default occurs, if we are unable 
or unwilling to continue the HIV program, TB program, vaccinal antibody program or, if applicable, the mutually agreed additional program (except for 
scientific or technical reasons), or if we institute bankruptcy or insolvency proceedings, then the Bill & Melinda Gates Foundation will have the right to 
exercise a non-exclusive, fully-paid license (with the right to sublicense) under our intellectual property to the extent necessary to use, make and sell 
products arising from such programs, in each case solely to the extent necessary to benefit people in the developing countries in furtherance of the Bill & 
Melinda Gates Foundation’s charitable purpose.

In the event that we sell, exclusively license or transfer to a third party all or substantially all of our assets, the technology platform, or products 

arising from programs that are funded using the proceeds of the Bill & Melinda Gates Foundation’s investment, such third party is required to assume our 
specified global access commitments on terms that are reasonably acceptable to the Bill & Melinda Gates Foundation. Additionally, we will not grant to 
any third party any rights or enter into any agreement with any third party that would restrict the Bill & Melinda Gates Foundation’s rights with respect to 
our specified global access commitments unless such third party expressly assumes such commitments to the reasonable satisfaction of the Bill & Melinda 
Gates Foundation. Consistent with the foregoing restriction, we also specifically will not 

48

 
enter into any such agreement negotiated in connection with a decision by us not to pursue the technology platform controlled by us as a result of our 
acquisition of TomegaVax. The global access commitments will continue for as long as the Bill & Melinda Gates Foundation continues to be a charitable 
entity.

In connection with the purchase of $40.0 million of shares of our common stock in January 2022, we entered into a stock purchase agreement, or the 

Gates Stock Purchase Agreement, with the Bill & Melinda Gates Foundation. The Bill & Melinda Gates Foundation purchased the shares of our common 
stock at $45.3841 price per share, which is the average of the volume weighted average price of a share of our common stock for the 30 trading day period 
prior to the date of the Gates Stock Purchase Agreement. The Gates Stock Purchase Agreement provides that until the first anniversary of the closing date, 
the Bill & Melinda Gates Foundation will hold and not sell any of the shares purchased pursuant to the Gates Stock Purchase Agreement, subject to certain 
exceptions. We have also agreed to register the shares for resale following expiration of the one-year lock-up period if Rule 144 under the Securities Act of 
1933, as amended, is not available for such resale without any volume or manner of sale restrictions.

Separately, in January 2018, March 2018 and January 2022, we entered into three grant agreements with the Bill & Melinda Gates Foundation, 

pursuant to which the Bill & Melinda Gates Foundation agreed to grant additional funding to us for our HIV, TB and vaccinal antibody programs, 
respectively, through the award of three research grants totaling in the aggregate up to $12.2 million with respect to the HIV program, up to $14.9 million 
with respect to the TB program, and up to $10.0 million with respect to the vaccinal antibody program if we achieve all the specified research and 
development milestones or reporting deliverables under the grants. In February 2020, we amended the HIV grant agreement pursuant to which we were 
awarded with a supplemental grant of $8.6 million. In addition, the term of the HIV grant agreement was extended through October 31, 2022. The TB grant 
agreement will remain in effect until March 31, 2022. As of December 31, 2021, we had received $19.7 million with respect to the HIV program and $12.2 
million with respect to the TB program. 

In November 2021, we entered into a grant agreement with the Bill & Melinda Gates Foundation under which we were awarded a grant totaling up 
to $10.0 million to support the manufacturing and clinical activities of our HIV and TB vaccine programs. This grant agreement will remain in effect until 
August 30, 2023. As of December 31, 2021, we had received $5.5 million under this grant agreement.

The grant agreements may be terminated early by the Bill & Melinda Gates Foundation for our breach, failure to progress the applicable funded 

projects, in the event of our change of control, change in our tax status, or significant changes in our leadership that the Bill & Melinda Gates Foundation 
reasonably believes may threaten the success of the applicable project.

Our Acquisition Agreements 

Agreement and Plan of Merger with TomegaVax 

In September 2016, we entered into an agreement and plan of merger with TomegaVax, or the TomegaVax Merger Agreement, pursuant to which we 

purchased all equity interests of TomegaVax, a preclinical private biotechnology company. The primary asset purchased in the acquisition was a CMV 
vector-based vaccine platform for the development of products directed to HBV, HIV and TB. 

49

 
In connection with the entry into the TomegaVax Merger Agreement, we also entered into a letter agreement with TomegaVax, or the TomegaVax 

Letter Agreement, which provides for certain payments to TomegaVax’s former stockholders prior to September 2024, in each case so long as we are 
continuing to pursue the development of the TomegaVax technology. Under the terms of the TomegaVax Letter Agreement, we will be required to pay to 
the former stockholders of TomegaVax milestone payments of up to an aggregate of $30.0 million if the per-share price of our publicly traded common 
stock, or implied price per share of our Series A-1 convertible preferred stock (or common stock upon conversion) upon a certain asset sale, merger or 
stock sale, is at least $45 (as adjusted in the case of any stock dividend, stock split or other similar recapitalization), with the amount of such payments 
determined by the share price and/or the stage of our clinical development at the time of the relevant event triggering the payment. The share price of our 
publicly traded common stock will be determined using the average of the daily volume-weighted average trading price of our common stock for each 
trading day during a consecutive 90-day period. The foregoing payments are payable (i) during any date after the completion of an initial public offering by 
the company or any successor or affiliate controlling the TomegaVax technology, provided that no payment will be due before the first anniversary of the 
initial public offering, (ii) upon the sale of all assets related to the TomegaVax technology or (iii) upon a merger or stock sale of the company or any 
successor or affiliate controlling the TomegaVax technology, in each case subject to certain conditions with respect to the timing of the payments. The 
payments under the TomegaVax Letter Agreement can be made in cash or shares of our common stock, at the discretion of our board of directors. 

The TomegaVax Letter Agreement may be amended, modified or terminated and the observance of any term may be waived only with the written 

consent of the stockholders’ representative (as such term is defined in the TomegaVax Merger Agreement) and us.

In February 2021, we achieved one of the milestones related to the specified per-share price of our common stock, which resulted in a $10.0 million 
payable to TomegaVax’s former stockholders. In July 2021, we made the milestone payment to the former TomegaVax stockholders through a combination 
of $8.1 million in cash and the issuance of 42,737 shares of common stock with a total fair value of $1.9 million. The remaining milestone payments of up 
to $20.0 million in the aggregate will be triggered if (i) the per-share price of our publicly traded common stock is at least $45 (as adjusted in the case of 
any stock dividend, stock split or other similar recapitalization) and upon the achievement of a certain milestone related to the stage of our clinical 
development at the time of the relevant event triggering the payment and/or (ii) the per-share price of our publicly traded common stock is at least $90 (as 
adjusted in the case of any stock dividend, stock split or other similar recapitalization).

Securities Purchase Agreement with Humabs 

In August 2017, we entered into a securities purchase agreement with Humabs and its securities holders, or the Humabs SPA, pursuant to which we 

purchased all equity interests of Humabs. Pursuant to the Humabs SPA, we are required to pay up to $135.0 million upon the first achievement of certain 
clinical, regulatory and commercial milestones for an HBV product, or the HBV Milestones, and up to $105.0 million upon the first achievement of certain 
clinical, regulatory and commercial milestones for another product. Pursuant to the Humabs SPA, we are required to use commercially reasonable efforts to 
achieve such milestones during a specified period following the closing of the Humabs acquisition. In addition, Humabs’ securities holders are also entitled 
to receive certain pass-through payments that Humabs receives under certain license agreements, including the 2012 MedImmune Agreement, following 
deduction of certain expenses incurred by us or Humabs thereunder. 

Sales and Marketing 

Given our stage of development, we have not yet established a commercial organization or distribution capabilities. We intend to build a commercial 

infrastructure to support sales of our product candidates. We expect to manage sales, marketing and distribution through internal resources and third-party 
relationships. While we may commit significant financial and management resources to commercial activities, we will also consider collaborating with one 
or more pharmaceutical companies to enhance our commercial capabilities.

Manufacturing 

We are currently manufacturing product candidates from three of our platforms: antibodies, T cells and siRNAs. We have established our own 
internal process development, manufacturing and quality capabilities and are working with contract development and manufacturing organizations, or 
CDMOs, to supply our early- and late-stage product candidates in the near term. We continue to expand our internal capabilities and resources in process 
development, analytical development, quality, manufacturing and supply chain, which are supported by our San Francisco, California, and Portland, 
Oregon facilities that include laboratories for process development, production of HCMV research viral seed stock and selected quality control testing for 
our product candidates. 

We have established relationships with multiple CDMOs and have produced material to support preclinical studies and Phase 1, Phase 2 and Phase 3 

clinical trials. Material for any Phase 3 clinical trials and commercial supply will generally require large-volume, low-cost-of-goods production. For 
example, for our COVID-19 program, we and our collaborator GSK have executed manufacturing agreements with CDMOs having large-scale capacity to 
support future scale-up and product supply, particularly for potential commercialization. However, there are no assurances that our manufacturing and 
supply chain infrastructure will remain uninterrupted and reliable, or that the third parties we rely on to manufacture our COVID-19 therapies will be able 
to satisfy demand in a timely manner or not have supply chain disruptions due to COVID-19 related shutdowns, stock-outs due to raw material shortages 
and/or greater than anticipated demand or quality issues given the operational challenges and raw material shortages that have been experienced during the 
COVID-19 pandemic.

Production Modalities 

Antibody Platform 

The technology and industrial processes for producing mAbs are well-established across the biopharmaceutical industry. Over the last 30 years, 
process optimization and standardization has enabled process portability and facilitated manufacturing with high success rates at most biologic CDMOs, as 
well as the partnered use of excess capacity with other biopharmaceutical companies. We rely on the mAb process platforms and manufacturing facilities of 
our CDMOs and strategic collaborators for all of our product candidate clinical supplies. For our COVID-19 program, we and our collaborator GSK have 
executed manufacturing agreements with large-scale CDMOs to support future scale-up and capacity, particularly for potential commercialization. 

T Cell Platform 

Our T cell platform is based on genetically engineered HCMV. We have attenuated the HCMV for the purpose of patient safety, but this attenuation 

also reduces its yield in production. To improve manufacturing efficiency and scale-up, we have made significant internal investments in process 
development, largely funded by the Bill & Melinda Gates Foundation. We have established a reproducible current Good Manufacturing Practices, or 
cGMP, manufacturing process in support of Phase 1 and Phase 2 clinical trials that has been successfully transferred and executed at CDMOs specializing 
in live virus manufacturing. 

siRNA Platform 

Alnylam is currently supplying clinical material from their CDMO sites for the current VIR-2218 clinical trials. We initiated a technology transfer of 

the manufacturing process at the same CDMO sites in the second half of 2021 and will assume responsibility for all additional clinical manufacturing 
including Phase 3 supplies in the first half of 2022 and subsequently for all commercial manufacturing in advance of any Phase 3 clinical trial. In addition 
to the current CDMOs supplying our clinical trials, other CDMOs as well as Alnylam are capable of producing kilogram-scale batches of siRNA and we 
may contract for scale-up and Phase 3 manufacturing at one of these qualified facilities.

Manufacturing Agreements

In connection with the ongoing COVID-19 pandemic, we have entered into the following agreements to date in support of our COVID-19 program:

Letter Agreement, Assignment and Master Services Agreement with Samsung 

In April 2020, we entered into a binding letter agreement with Samsung pursuant to which Samsung will perform process development and 
manufacturing services for our SARS-CoV-2 mAbs. Under the terms of the letter agreement, we had committed to purchase a firm and binding capacity 
reservation for a specified number of drug substance manufacturing slots in 2021 and 2022. Samsung will reserve such manufacturing slots on a non-
cancellable, non-adjustable basis and will not offer such manufacturing slots under our capacity reservation to third parties. We were obligated to pay a 
total of approximately $362.0 million for such capacity reservation on a take-or-pay basis regardless of whether such manufacturing slots are utilized by us, 
subject to annual adjustment based on the Korean Consumer Price Index. The amounts were to be payable during 2021 and 2022 and invoiced on a per-
batch basis, with shortfalls invoiced at the end of the year in which such shortfall occurs. 

In August 2020, we entered into an Assignment and Novation Agreement with GlaxoSmithKline Trading Services Limited, or GSKTSL, and 

Samsung effective as of July 31, 2020 pursuant to which we assigned and transferred to GSKTSL all of our right, title, and interest in, to and under the 
letter agreement, and GSKTSL became our successor in interest in and to all of our rights, duties, and obligations in, to and under the letter agreement. On 
August 4, 2020, GSKTSL entered into a Master Services Agreement with Samsung effective as of July 31, 2020, or the Samsung MSA, thereby 
superseding the letter agreement, and pursuant to which, among other things, Samsung will perform technology transfer, development, and manufacturing 
services for clinical and commercial supply of antibody products under our SARS-CoV-2 antibody program.

Development and Manufacturing Collaboration Agreement with WuXi Biologics

In February 2020, we entered into a development and manufacturing collaboration agreement with WuXi Biologics for the clinical development, 

manufacturing, and commercialization of our proprietary antibodies developed for SARS-CoV-2. Under the agreement, WuXi Biologics will conduct cell-
line development, process and formulation development, and initial manufacturing for clinical development. WuXi Biologics will have the right to 
commercialize products incorporating such SARS-CoV-2 antibodies in greater China pursuant to an exclusive license granted for the selected SARS-CoV-2 
antibodies that have been developed. We will have the right to commercialize such products in all other markets worldwide.

WuXi Biologics will perform mutually agreed process and clinical development and manufacturing activities, under individual statements of work. 

In addition, the parties agreed that WuXi Biologics will pay us tiered royalties at percentages ranging from the high single-digits to mid-teens on annual net 
sales of all products sold by WuXi Biologics in greater China. 

Letter Agreement, Assignment and Master Services Agreement with WuXi Biologics 

In June 2020, we entered into a binding letter of intent with WuXi Biologics pursuant to which WuXi Biologics will perform certain development 

and manufacturing services for our SARS-CoV-2 antibody program. Under the terms of the letter of intent, we had committed to purchase a firm and 
binding capacity reservation for the manufacture of a specified number of batches of drug substance of our SARS-CoV-2 antibody in 2020 and 2021. In 
addition, we had the right to order an additional specified number of batches of drug substance, provided we make such election by a specified date in the 
fourth calendar quarter in 2020. WuXi Biologics is obligated to reserve such manufacturing slots on a non-cancellable basis, and will manufacture the 
agreed number of batches of drug substance in accordance with an agreed manufacturing schedule. We were obligated to pay a total of approximately 
$130.0 million for such capacity reservation, if all batches are manufactured, inclusive of estimated raw material costs, with between 70% and 80% of the 
batch production fees owed to WuXi Biologics on a take-or-pay basis regardless of whether we utilize such manufacturing slots. The amounts were to be 
payable during 2020 and 2021 and invoiced on a per-batch basis. The SARS-CoV-2 antibody drug substance contemplated to be manufactured in 
accordance with the terms of the letter of intent will be utilized in connection with progressing the development and commercialization of the SARS-CoV-2 
antibody product under our collaboration with GSK.

52

 
In August 2020, we entered into an Assignment and Novation Agreement with GSKTSL and WuXi Biologics effective as of July 29, 2020 pursuant 
to which we assigned and transferred to GSKTSL all of our right, title, and interest in, to and under the letter of intent, and GSKTSL became our successor 
in interest in and to all of our rights, duties, and obligations in, to and under the letter of intent. On August 4, 2020, GSKTSL entered into a non-exclusive 
Master Services Agreement for Commercial Manufacture of Drug Substance with WuXi Biologics effective as of July 29, 2020, or the WuXi Biologics 
MSA, thereby superseding the letter of intent, and pursuant to which, among other things, WuXi Biologics will perform development and manufacturing 
services for clinical and commercial supply of antibody products under our SARS-CoV-2 antibody program. 

GSKTSL entered into the WuXi Biologics MSA and Samsung MSA in connection with the performance of GSK and our obligations pursuant to the 

2020 GSK Agreement. In accordance with the terms of the 2020 GSK Agreement, we will continue to be responsible for 72.5% of the costs under each of 
the WuXi Biologics MSA and Samsung MSA, and GSK will bear 27.5% of such costs under each of the Samsung MSA and the WuXi Biologics MSA, 
subject to certain conditions and exceptions.

Clinical Development and Manufacturing Agreement with Biogen

In May 2020, we entered into a clinical development and manufacturing agreement with Biogen pursuant to which Biogen will perform process 

development activities and specified manufacturing services under agreed statements of work for certain pre-commercial and clinical supply of our SARS-
CoV-2 mAbs. We also agreed to collaborate with Biogen to develop highly productive clonal cell lines and clinical and commercial manufacturing 
processes for our SARS-CoV-2 mAbs. These processes are designed to be transferrable to global biomanufacturing facilities designed for advanced 
biologics production. Under the agreement, Biogen will conduct cGMP clinical manufacturing in the United States and provide technical support to 
facilitate process transfer to Samsung, and potentially other large-scale biomanufacturing facilities in the United States and other regions of the world to 
enable us to obtain a reliable supply of a potential commercial product.

Under the terms of the Biogen agreement, we have agreed to pay fees for Biogen’s performance of services as provided in each applicable statement 

of work, including costs to third parties on a pass-through basis. We entered into three statements of work with Biogen for the process development and 
certain clinical manufacturing services simultaneously with the execution of the agreement, with the cost of activities under such agreed statements of work 
totaling approximately $13.8 million. In October 2021, pursuant to the terms of this agreement, we terminated all outstanding statements of work with 
Biogen.  

Competition 

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. 

While we believe that our technology, the expertise of our executive and scientific team, research, clinical capabilities, development experience and 
scientific knowledge provide us with competitive advantages, we face increasing competition from many different sources, including pharmaceutical and 
biotechnology companies, academic institutions, governmental agencies and public and private research institutions. Product candidates that we 
successfully develop and commercialize may compete with existing therapies and new therapies that may become available in the future. For example, the 
industry and competitive landscape for COVID-19 treatments is rapidly changing, which could result in more competition from new and existing therapies 
in the future.

Many of our competitors, either alone or with their collaborators, have significantly greater financial resources, established presence in the market, 

expertise in research and development, manufacturing, preclinical and clinical testing, obtaining regulatory approvals and reimbursement and marketing 
approved products than we do. These competitors also compete with us in recruiting and retaining qualified scientific, sales, marketing and management 
personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or potentially 
necessary for, our programs. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative 
arrangements with large and established companies. Additional mergers and acquisitions may result in even more resources being concentrated in our 
competitors. 

53

 
 
Our commercial potential could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have 

fewer or less severe side effects, are more convenient or are less expensive than products that we may develop. Our competitors also may obtain FDA or 
other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong 
market position before we are able to enter the market or make our development more complicated. The key competitive factors affecting the success of all 
of our programs are likely to be efficacy, safety, convenience, and cost/access. 

COVID-19

There are limited FDA-approved treatments and prophylactic vaccines for COVID-19 and several treatments and a prophylactic vaccine are 
available under EUA. An IV administered antiviral, remdesivir, marketed by Gilead, is FDA-approved for treatment in the hospitalized and early-treatment 
settings. Currently, Eli Lilly and Company's antibody, bebtelovimab, is also available under EUA for the treatment of COVID-19 in the mild to moderate 
setting. Oral antiviral therapies from Merck & Co, Inc., or Merck, and Pfizer Inc., or Pfizer (molnupiravir and nirmatrelvir, respectively), are also available 
under EUA in the mild to moderate early treatment setting. Additionally, Pfizer’s COVID-19 vaccine, Comirnaty®, was approved by the FDA for 
individuals 16 years of age or older, Moderna, Inc.'s COVID-19 vaccine, Spikevax®, was approved by the FDA for individuals 18 years of age or older and 
a COVID-19 vaccine is available in the United States under EUA from Janssen Biotech, Inc. Numerous large and small pharmaceutical and biotechnology 
companies are developing programs with various mechanisms of actions, including prophylactic vaccines, oral antivirals, immunomodulators, and 
antibodies, some of which are further along in the development process than we are. Companies with antibodies in clinical development include AbbVie, 
Inc., Adagio Therapeutics, Inc., or Adagio, AstraZeneca plc, or AstraZeneca, Brii Bio, Celltrion Healthcare Co., Ltd. and Regeneron Pharmaceuticals, Inc. 
Companies with oral antivirals in clinical development include Shionogi Inc., Gilead and others. Companies with prophylactic vaccines in clinical 
development include AstraZeneca, GSK, Novavax, Inc. and Sanofi S.A. In addition, COVID-19 treatment standards are susceptible to rapid changes in 
epidemiology and the emergence of new variants, thus, sotrovimab may be rendered inferior or obsolete in the future.

HBV 

Current FDA-approved treatments for chronic HBV infection include PEG-IFN-α, marketed by Roche, and oral antiviral agents such as NRTIs, 
marketed by Gilead and Bristol-Myers Squibb Company. These treatments do not lead to either a functional or a complete cure in the vast majority of 
patients, and in the case of NRTIs, require life-long therapy. Several large and small pharmaceutical companies are developing programs with various 
mechanisms of action, to be used alone or in combination, with the goal of achieving an HBV functional or complete cure. Companies with RNAi agents in 
clinical development include Arbutus Biopharma Corporation, Janssen Pharmaceuticals, Inc., or Janssen (part of Johnson & Johnson, in partnership with 
Arrowhead Pharmaceuticals, Inc.), and Roche Holding AG, or Roche, (in partnership with Dicerna Pharmaceuticals, Inc.) In addition, GC Pharma is 
developing an antibody against surface antigen. Several companies, including Altimmune, Inc., GSK, Janssen, Vaccitech plc and Transgene SA, have 
therapeutic vaccines in late-preclinical or early-clinical development. 

Influenza 

There are numerous approved seasonal flu vaccines, including trivalent, quadrivalent, high-dose, and adjuvanted products, marketed by GSK, Sanofi 
Pasteur, and Seqirus (owned by CSL Limited). In addition, there are approved antiviral agents to treat influenza, such as Xofluza and Tamiflu, marketed by 
Roche, as well as other neuraminidase inhibitors. Cidara Therapeutics, Inc. (in partnership with Janssen) is working to develop an antiviral conjugate which 
could be a novel method for long-acting prophylaxis.

While several companies, including AstraZeneca, Janssen and Roche, have conducted clinical trials of antibodies for the treatment of influenza, to 

our knowledge, there are no other prophylactic antibodies currently in clinical development. Adagio has stated that it intends to develop prophylactic 
antibodies for influenza. 

Several vaccines are in clinical development from large and small pharmaceutical companies including GSK (in partnership with CureVac N.V.), 

Moderna, Inc., Novavax, Inc., Pfizer (in partnership with BioNTech SE) and Sanofi S.A. (in partnership with Translate Bio). Some aim to improve efficacy 
or convenience over existing seasonal vaccines, and others are pursuing a universal flu vaccine approach with broad strain coverage and at least one year of 
protection. 

54

 
HIV 

No FDA-approved vaccine is currently available for the prevention of HIV. Several large and small pharmaceutical companies, including GSK, 

GeoVax Labs, Inc., Janssen, Profectus Biosciences, Inc. and Sanofi S.A. are actively engaged in vaccine research and development in this area. These and 
other companies are developing vaccines using viral vectors, nanoparticles, DNA, or formulations, with the goal of stimulating T cell-mediated and/or 
neutralizing antibody responses against HIV. To our knowledge, none are using a CMV-based vector. Numerous clinical trials of these vaccines are ongoing 
with support from the NIH Vaccine Research Center, the Bill & Melinda Gates Foundation, the U.S. military, the International AIDS Vaccine Initiative, the 
European Vaccine Initiative, the South African AIDS Initiative, and their academic and industry partners. In addition, many of these institutions, as well as 
pharmaceutical companies like Gilead and Viiv Healthcare Limited, or Viiv, are also studying the passive transfer of broadly neutralizing antibodies against 
HIV for prophylactic and therapeutic applications. 

We may also compete with oral or long-acting antiretroviral therapies for pre-exposure prophylaxis of HIV. Truvada, marketed by Gilead, is a once-

daily therapy approved for this indication. Viiv recently received FDA approval for long-acting antiretroviral therapy, cabotegravir for pre-exposure 
prophylaxis of HIV. Gilead, Janssen, Merck and Viiv have additional long-acting formulations in development. 

Intellectual Property 

Our intellectual property is critical to our business and we strive to protect it, including by obtaining and maintaining patent protection in the United 

States and internationally for our product candidates, new therapeutic approaches and potential indications, and other inventions that are important to our 
business. Our policy is to seek to protect our proprietary and intellectual property position by, among other methods, filing U.S. and foreign patent 
applications related to our proprietary technology, inventions and improvements that are important for the development and implementation of our 
business. We also rely on the skills, knowledge and experience of our scientific and technical personnel, as well as that of our advisors, consultants and 
other contractors. To help protect our proprietary know-how that is not patentable, we rely on confidentiality agreements to protect our interests. We require 
our employees, consultants and advisors to enter into confidentiality agreements prohibiting the disclosure of confidential information and requiring 
disclosure and assignment to us of the ideas, developments, discoveries and inventions important to our business.

Innate Immunity Platform 

We have know-how relating to our innate immunity platform and are continually developing our intellectual property in this area, as well as 

evaluating external technologies and assets that may also help grow this platform. 

We do not currently license or own any patents related to our innate immunity platform.  

Patent Term and Term Extensions 

Individual patents have terms for varying periods depending on the date of filing of the patent application or the date of patent issuance and the legal 

term of patents in the countries in which they are obtained. Generally, utility patents issued for applications filed in the United States are granted a term of 
20 years from the earliest effective filing date of a non-provisional patent application. In addition, in certain instances, the term of a U.S. patent can be 
extended to recapture a portion of the U.S. Patent and Trademark Office, or the USPTO, delay in issuing the patent as well as a portion of the term 
effectively lost as a result of the FDA regulatory review period. However, as to the FDA component, the restoration period cannot be longer than five years 
and the restoration period cannot extend the patent term beyond 14 years from FDA approval. In addition, only one patent applicable to an approved drug is 
eligible for the extension, and only those claims covering the approved drug, a method for using it, or a method of manufacturing may be extended. The 
duration of foreign patents varies in accordance with provisions of applicable local law, but typically is also 20 years from the earliest effective filing date. 
All taxes, annuities or maintenance fees for a patent, as required by the USPTO and various foreign jurisdictions, must be timely paid in order for the patent 
to remain in force during this period of time. 

The actual protection afforded by a patent may vary on a product by product basis, from country to country, and can depend upon many factors, 

including the type of patent, the scope of its coverage, the availability of regulatory-related extensions and the availability of legal remedies in a particular 
country and the validity and enforceability of the patent. 

Our patents and patent applications may be subject to procedural or legal challenges by others. We may be unable to obtain, maintain and protect the 

intellectual property rights necessary to conduct our business, and we may be subject to claims that we infringe or otherwise violate the intellectual 
property rights of others, which could materially harm our business. For more information, see the section titled “Risk Factors—Risks Related to Our 
Intellectual Property.” 

Trademarks and Know-How 

In connection with the ongoing development and advancement of our products and services in the United States and various international 
jurisdictions, we seek to create protection for our marks and enhance their value by pursuing trademarks and service marks where available and when 
appropriate. In addition to patent and trademark protection, we rely upon know-how and continuing technological innovation to develop and maintain our 
competitive position. We seek to protect our proprietary information, in part, by using confidentiality agreements with our commercial partners, 
collaborators, employees and consultants, and invention assignment agreements with our employees and consultants. These agreements are designed to 
protect our proprietary information and, in the case of the invention assignment agreements, to grant us ownership of technologies that are developed by 
our employees and through relationships with third parties. These agreements may be breached, and we may not have adequate remedies for any breach. In 
addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our contractors, commercial 
partners, collaborators, employees, and consultants use intellectual property owned by others in their work for us, disputes may arise as to the rights in 
related or resulting know-how and inventions. For more information, see the section titled “Risk Factors—Risks Related to Our Intellectual Property.” 

Government Regulation and Product Approval 

The FDA and other regulatory authorities at federal, state and local levels, as well as in foreign countries, extensively regulate, among other things, 

the research, development, testing, manufacture, quality control, import, export, safety, 

63

 
 
 
 
effectiveness, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, post-approval monitoring and post-
approval reporting of drugs and biologics such as those we are developing. 

In the United States, the FDA approves and regulates drugs under the Federal Food, Drug, and Cosmetic Act, or the FDCA. Biological products, or 

biologics, are licensed for marketing under the Public Health Service Act, or the PHSA, and regulated under the FDCA. A company, institution, or 
organization which takes responsibility for the initiation and management of a clinical development program for such products is typically referred to as a 
sponsor. We, along with third-party contractors, will be required to navigate the various preclinical, clinical and commercial approval requirements of the 
governing regulatory agencies of the countries in which we wish to conduct studies or trials or seek approval or licensure of our product candidates. 

U.S. Biopharmaceuticals Regulation 

The process required by the FDA before drug and biologic product candidates may be marketed in the United States generally involves the 

following: 

•

•

•

•

•

•

•

•

•

•

completion of extensive preclinical laboratory tests and animal trials performed in accordance with applicable regulations, including the 
FDA’s Good Laboratory Practice, or GLP, regulations; 

design of a clinical protocol and submission to the FDA of an IND application which must become effective before clinical trials may begin; 

approval by an independent institutional review board or ethics committee at each clinical site before the trial is commenced; 

performance of adequate and well-controlled human clinical trials in accordance with FDA’s Good Clinical Practice, or GCP, regulations to 
establish the safety and efficacy of a drug candidate and safety, purity and potency of a proposed biologic product candidate for its intended 
purpose; 

preparation of and submission to the FDA of a new drug application, or NDA, or BLA, as applicable, after completion of all pivotal clinical 
trials; 

satisfactory completion of an FDA Advisory Committee review, if applicable; 

a determination by the FDA within 60 days of its receipt of an NDA or BLA to file the application for review; 

satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the proposed product is 
produced to assess compliance with cGMPs and of selected clinical investigation sites to assess compliance with GCPs;  

FDA review and approval of an NDA or BLA to permit commercial marketing of the product for particular indications for use in the United 
States; and

completion of any post-approval requirements, including the potential requirement to implement a risk evaluation and mitigation strategy, or 
REMS, and any post-approval studies required by the FDA. 

Preclinical and Clinical Development 

Prior to beginning the first clinical trial with a product candidate, we must submit an IND to the FDA. An IND is a request for authorization from 
the FDA to administer an investigational new drug product to humans. The central focus of an IND submission is on the general investigational plan and 
the protocol or protocols for preclinical studies and clinical trials. The IND also includes results of animal and in vitro studies assessing the toxicology, 
pharmacokinetics, pharmacology and pharmacodynamic characteristics of the product, chemistry, manufacturing and controls information, and any 
available human data or literature to support the use of the investigational product. An IND must become effective before human clinical trials may begin. 
The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day period, raises safety concerns or questions 
about the proposed clinical trial. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding 
concerns or questions before the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical 
trial. 

Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in 
accordance with GCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical study. 
Clinical trials are conducted under protocols detailing, among 

64

 
other things, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission 
to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments. 
Furthermore, an independent institutional review board for each site proposing to conduct the clinical trial must review and approve the plan for any 
clinical trial and its informed consent form before the clinical trial begins at that site, and must monitor the trial until completed. 

Regulatory authorities, the institutional review board or the sponsor may suspend a clinical trial at any time on various grounds, including a finding 
that the subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some trials also include oversight 
by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board, which provides authorization 
for whether or not a trial may move forward at designated check points based on access to certain data from the trial and may halt the clinical trial if it 
determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. 

For purposes of biopharmaceutical development, human clinical trials are typically conducted in three sequential phases that may overlap or be 

combined: 

•

•

•

Phase 1. The investigational product is initially introduced into patients with the target disease or condition. These trials are designed to test 
the safety, dosage tolerance, absorption, metabolism and distribution of the investigational product in humans, the side effects associated with 
increasing doses, and, if possible, to gain early evidence on effectiveness. 

Phase 2. The investigational product is administered to a limited patient population to evaluate the preliminary efficacy, optimal dosages and 
dosing schedule and to identify possible adverse side effects and safety risks. 

Phase 3. The investigational product is administered to an expanded patient population to further evaluate dosage, to provide statistically 
significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical trial sites. These 
clinical trials are intended to establish the overall risk/benefit ratio of the investigational product and to provide an adequate basis for product 
approval. 

In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a product is approved to gain more 
information about the product. These so-called Phase 4 trials may be made a condition to approval of the application. Concurrent with clinical trials, 
companies may complete additional animal trials and develop additional information about the characteristics of the product candidate, and must finalize a 
process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of 
consistently producing quality batches of the product candidate and, among other things, must develop methods for testing the identity, strength, quality 
and purity of the final product, or for biologics, the safety, purity and potency. Additionally, appropriate packaging must be selected and tested and stability 
trials must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data, and 

clinical trial investigators. The FDA or the sponsor or its data safety monitoring board may suspend a clinical trial at any time on various grounds, 
including a finding that the research patients or patients are being exposed to an unacceptable health risk. Similarly, an institutional review board can 
suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the institutional review 
board’s requirements or if the biological product candidate has been associated with unexpected serious harm to patients. 

A sponsor may choose, but is not required, to conduct a foreign clinical study under an IND. When a foreign clinical study is conducted under an 

IND, all IND requirements must be met unless waived by the FDA. When a foreign clinical study is not conducted under an IND, the sponsor must ensure 
that the study complies with certain regulatory requirements of the FDA in order to use the study as support for an IND or application for marketing 
approval. Specifically, the studies must be conducted in accordance with GCP, including undergoing review and receiving approval by an independent 
ethics committee and seeking and receiving informed consent from subjects.

Under the PHSA, sponsors of clinical trials are required to register and disclose certain clinical trial information on a public registry 

(clinicaltrials.gov) maintained by the NIH. In particular, information related to the product, patient population, phase of investigation, study sites and 
investigators and other aspects of the clinical trial is made public as part of the registration of the clinical trial. The failure to submit clinical trial 
information to clinicaltrials.gov, as required, is a prohibited act under the FDCA with violations subject to potential civil monetary penalties of up to 
$10,000 for each day the violation continues.

NDA/BLA Submission and Review 

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product 
development, nonclinical trials and clinical trials are submitted to the FDA as part of an NDA or BLA, as applicable, requesting approval to market the 
product for one or more indications. The application must include all relevant data available from pertinent preclinical studies and clinical trials, including 
negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls, 
and proposed labeling, among other things. The submission of an application requires payment of a substantial application user fee to the FDA, unless a 
waiver or exemption applies. The FDA has sixty days from the applicant’s submission to either issue a refusal to file letter, or RTF, or accept the 
application for filing, indicating that it is sufficiently complete to permit substantive review. 

Once an NDA or BLA has been accepted for filing, the FDA’s goal is to review standard applications within 10 months after it accepts the 
application for filing, or, if the application qualifies for priority review, six months after the FDA accepts the application for filing. In both standard and 
priority reviews, the review process is often significantly extended by FDA requests for additional information or clarification. The FDA reviews an NDA 
to determine whether a drug is safe and effective for its intended use and a BLA to determine whether a biologic is safe, pure and potent. The FDA also 
reviews whether the facility in which the product is manufactured, processed, packed or held meets standards designed to assure and preserve the product’s 
identity, safety, strength, quality, potency and purity. The FDA may convene an advisory committee to provide clinical insight on application review 
questions. Before approving an NDA or BLA, the FDA will typically inspect the facility or facilities where the product is manufactured. The FDA will not 
approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to 
assure consistent production of the product within required specifications. Additionally, before approving an application, the FDA will typically inspect one 
or more clinical sites to assure compliance with GCPs. 

After the FDA evaluates an application and conducts inspections of manufacturing facilities where the investigational product and/or its drug 

substance will be manufactured, the FDA may issue an approval letter or a Complete Response letter, or CRL. An approval letter authorizes commercial 
marketing of the product with specific prescribing information for specific indications. A CRL will describe all of the deficiencies that the FDA has 
identified in the application, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA 
may issue the CRL without first conducting required inspections, testing submitted product lots and/or reviewing proposed labeling. In issuing the CRL, 
the FDA may recommend actions that the applicant might take to place the application in condition for approval, including requests for additional 
information or clarification, which may include the potential requirement for additional clinical trials. The FDA may delay or refuse approval of an 
application if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance 
to monitor safety or efficacy of a product.

If regulatory approval of a product is granted, such approval will be granted for particular indications and may entail limitations on the indicated 

uses for which such product may be marketed. For example, the FDA may approve the application with a REMS to ensure the benefits of the product 
outweigh its risks. A REMS is a safety strategy to manage a known or potential serious risk associated with a product and to enable patients to have 
continued access to such medicines by managing their safe use, and could include medication guides, physician communication plans, or elements to assure 
safe use, such as restricted distribution methods, patient registries and other risk minimization tools. The FDA also may condition approval on, among 
other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product 
approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The 
FDA may require one or more Phase 4 post-market trials and surveillance to further assess and monitor the product’s safety and effectiveness after 
commercialization, and may limit further marketing of the product based on the results of these post-marketing trials. 

66

 
Expedited Development and Review Programs 

The FDA offers a number of expedited development and review programs for qualifying product candidates. The fast track program is intended to 
expedite or facilitate the process for reviewing new products that meet certain criteria. Specifically, new products are eligible for fast track designation if 
they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for the disease or 
condition. Fast track designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a fast 
track product has opportunities for frequent interactions with the review team during product development and, once an NDA or BLA is submitted, the 
product may be eligible for priority review. A fast track product may also be eligible for rolling review, where the FDA may consider for review sections of 
the NDA or BLA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the 
application, the FDA agrees to accept sections of the application and determines that the schedule is acceptable, and the sponsor pays any required user fees 
upon submission of the first section of the application. 

A product intended to treat a serious or life-threatening disease or condition may also be eligible for breakthrough therapy designation to expedite its 

development and review. A product can receive breakthrough therapy designation if preliminary clinical evidence indicates that the product, alone or in 
combination with one or more other drugs or biologics, may demonstrate substantial improvement over existing therapies on one or more clinically 
significant endpoints, such as substantial treatment effects observed early in clinical development. The designation includes all of the fast track program 
features, as well as more intensive FDA interaction and guidance beginning as early as Phase 1 and an organizational commitment to expedite the 
development and review of the product, including involvement of senior managers. 

Any marketing application for a drug or biologic submitted to the FDA for approval, including a product with a fast track designation and/or 

breakthrough therapy designation, may be eligible for other types of FDA programs intended to expedite the FDA review and approval process, such as 
priority review and accelerated approval. A product is eligible for priority review if it has the potential to provide a significant improvement in the 
treatment, diagnosis or prevention of a serious disease or condition. Priority review designation means the FDA’s goal is to take action on the marketing 
application within six months of the 60-day filing date. 

Additionally, products studied for their safety and effectiveness in treating serious or life-threatening diseases or conditions may receive accelerated 

approval upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical 
endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or 
mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative 
treatments. As a condition of accelerated approval, the FDA will generally require the sponsor to perform adequate and well-controlled post-marketing 
clinical trials to verify and describe the anticipated effect on irreversible morbidity or mortality or other clinical benefit. In addition, the FDA currently 
requires as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch 
of the product. 

Fast track designation, breakthrough therapy designation and priority review do not change the standards for approval but may expedite the 
development or approval process. Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets 
the conditions for qualification or decide that the time period for FDA review or approval will not be shortened. 

Emergency Use Authorization 

In emergency situations, such as a pandemic, and with a declaration of a public health emergency by the Secretary of the Department of Health and 
Human Services, or HHS, the FDA has the authority to allow unapproved medical products or unapproved uses of cleared or approved medical products to 
be used to diagnose, treat or prevent serious or life-threatening diseases or conditions caused by chemical, biological, radiological or nuclear warfare threat 
agents when there are no adequate, approved, and available alternatives. 

67

 
Under this authority, the FDA may issue an EUA if the following four statutory criteria have been met: (1) a serious or life-threatening condition 

exists; (2) evidence of effectiveness exists; (3) a risk-benefit analysis shows that the benefits of the product outweigh the risks; and (4) no other alternatives 
exist for diagnosing, preventing or treating the disease or condition. The “may be effective” standard for EUAs requires a lower level of evidence than the 
“effectiveness” standard that FDA uses for product clearances or approvals in non-emergency situations. The FDA assesses the potential effectiveness of a 
possible EUA product on a case-by-case basis using a risk-benefit analysis. In determining whether the known and potential benefits of the product 
outweigh the known and potential risks, the FDA examines the totality of the scientific evidence to make an overall risk-benefit determination. Such 
evidence, which could arise from a variety of sources, may include (but is not limited to) results of domestic and foreign clinical trials, in vivo efficacy data 
from animal models, in vitro data, as well as the quality and quantity of the available evidence. 

Once granted, an EUA will remain in effect and generally terminate on the earlier of (1) the determination by the Secretary of HHS that the public 
health emergency has ceased or (2) a change in the approval status of the product such that the authorized use(s) of the product are no longer unapproved. 
After the EUA is no longer valid, the product is no longer considered to be legally marketed and one of the FDA’s non-emergency premarket pathways 
would be necessary to resume or continue distribution of the subject product. 

The FDA also may revise or revoke an EUA if the circumstances justifying its issuance no longer exist, the criteria for its issuance are no longer 

met, or other circumstances make a revision or revocation appropriate to protect the public health or safety.

On January 31, 2020, the Secretary of HHS issued a declaration of a public health emergency related to COVID-19. On February 4, 2020, HHS 
determined that COVID-19 represents a public health emergency that has a significant potential to affect national security or the health and security of U.S. 
citizens living abroad and, subsequently, declared on March 24, 2020, that circumstances exist to justify the authorization of emergency use of certain 
medical products, during the COVID-19 pandemic, subject to the terms of any authorization as issued by the FDA. The declaration of the Secretary of HHS 
has been further updated and the FDA has issued numerous guidances to sponsors seeking to obtain EUAs to diagnose and treat COVID-19.

Orphan Drug Designation 

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, which is a 

disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States for which there 
is no reasonable expectation that the cost of developing and making available in the United States a drug or biologic for this type of disease or condition 
will be recovered from sales in the United States for that drug or biologic. Orphan drug designation must be requested before submitting an NDA or BLA. 
After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. 
The orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review or approval process. Among the benefits 
of orphan drug designation are tax credits for certain research and a waiver of the NDA or BLA application fee.

If a product that has orphan drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the 

product is entitled to orphan drug exclusive approval (or exclusivity), which means that the FDA may not approve any other applications, including a full 
NDA or BLA, to market the same drug or biologic for the same indication for seven years, except in limited circumstances, such as a showing of clinical 
superiority to the product with orphan drug exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure 
the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. 
Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or 
biologic for a different disease or condition. 

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received 
orphan designation. In addition, exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was 
materially defective. In September 2021, the Court of Appeals for the 11th Circuit held that, for the purpose of determining the scope of market exclusivity, 
the term “same disease or condition” in the statute means the designated “rare disease or condition” and could not be interpreted by the FDA to mean the 
“indication or use.” Thus, the court concluded, orphan drug exclusivity applies to the entire designated disease or condition rather than the “indication or 
use.” It is unclear how this court decision will be implemented by the FDA.

68

 
Post-Approval Requirements 

Any products manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, 
including, among other things, requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, product sampling and 
distribution, and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other 
labeling claims, are subject to prior FDA review and approval. There also are continuing user fee requirements, under which the FDA assesses an annual 
program fee for each product identified in an approved NDA or BLA. Biopharmaceutical manufacturers and their subcontractors are required to register 
their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for 
compliance with cGMPs, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Changes to the 
manufacturing process are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented. 
FDA regulations also require investigation and correction of any deviations from cGMPs and impose reporting requirements upon us and any third-party 
manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality 
control to maintain compliance with cGMPs and other aspects of regulatory compliance. 

The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product 

reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or 
with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety 
information; imposition of post-market trials or clinical trials to assess new safety risks; or imposition of distribution restrictions or other restrictions under 
a REMS program. Other potential consequences include, among other things: 

•

•

•

•

•

•

•

•

restrictions on the marketing or manufacturing of a product, complete withdrawal of the product from the market or product recalls; 

fines, warning or untitled letters or holds on post-approval clinical trials; 

refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of existing product 
approvals; 

product seizure or detention, or refusal of the FDA to permit the import or export of products; 

consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programs; 

mandated modification of promotional materials and labeling and the issuance of corrective information; 

the issuance of safety alerts, Dear Healthcare Provider letters, press releases and other communications containing warnings or other safety 
information about the product; or 

injunctions or the imposition of civil or criminal penalties. 

The FDA closely regulates the marketing, labeling, advertising and promotion of biopharmaceutical products. A company can make only those 

claims relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved label. 
However, companies may share truthful and not misleading information that is otherwise consistent with a product’s FDA approved labeling. The FDA and 
other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. Failure to comply with these requirements can result 
in, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. Physicians may prescribe legally 
available products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label 
uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied 
circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s 
communications on the subject of off-label use of their products. In September 2021, the FDA published final regulations which describe the types of 
evidence that the FDA will consider in determining the intended use of a drug or biologic.

69

 
Biosimilars and Regulatory Exclusivity 

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively the ACA, signed 
into law in 2010, includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA, which created an abbreviated approval 
pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. The FDA has approved a 
number of biosimilars and the first interchangeable biosimilar product was approved on July 30, 2021, and a second product previously approved as a 
biosimilar was designated as interchangeable in October 2021. 

Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of 

safety, purity and potency, can be shown through analytical trials, animal trials and a clinical trial or trials. Interchangeability requires that a product is 
biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product in 
any given patient and, for products that are administered multiple times to an individual, the biologic and the reference biologic may be alternated or 
switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference 
biologic. 

Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference 

product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date 
on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the 
reference product if the FDA approves a full BLA for the competing product containing that applicant’s own preclinical data and data from adequate and 
well-controlled clinical trials to demonstrate the safety, purity and potency of its product. The BPCIA also created certain exclusivity periods for 
biosimilars approved as interchangeable products. Since passage of the BPCIA, many states have passed laws or amendments to laws that address 
pharmacy practices involving biosimilar products. 

Generic Drugs and Regulatory Exclusivity 

Section 505 of the FDCA describes three types of marketing applications that may be submitted to the FDA to request marketing authorization for a 
new drug. A Section 505(b)(1) NDA is an application that contains full reports of investigations of safety and efficacy. A 505(b)(2) NDA is an application 
that contains full reports of investigations of safety and efficacy but where at least some of the information required for approval comes from investigations 
that were not conducted by or for the applicant and for which the applicant has not obtained a right of reference or use from the person by or for whom the 
investigations were conducted. This regulatory pathway enables the applicant to rely, in part, on the FDA’s prior findings of safety and efficacy for an 
existing product, or published literature, in support of its application. Section 505(j) establishes an abbreviated approval process for a generic version of 
approved drug products through the submission of an Abbreviated New Drug Application, or ANDA. 

An ANDA provides for marketing of a generic drug product that has the same active ingredients, dosage form, strength, route of administration, 

labeling, performance characteristics and intended use, among other things, to a previously approved product. ANDAs are termed “abbreviated” because 
they are generally not required to include preclinical (animal) and clinical (human) data to establish safety and efficacy. Instead, generic applicants must 
scientifically demonstrate that their product is bioequivalent to, or performs in the same manner as, the innovator drug through in vitro, in vivo or other 
testing. The generic version must deliver the same amount of active ingredient(s) in the same amount of time as the innovator drug and can often be 
substituted by pharmacists under prescriptions written for the reference listed drug. In seeking approval for a drug through an NDA, applicants are required 
to list with the FDA each patent with claims that cover the applicant’s drug or a method of using the drug. Upon approval of a drug, each of the patents 
listed in the application for the drug is then published in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known 
as the Orange Book. Drugs listed in the Orange Book can, in turn, be cited by potential competitors in support of approval of an ANDA or 505(b)(2) NDA. 

70

 
Upon submission of an ANDA or a 505(b)(2) NDA, an applicant must certify to the FDA that (1) no patent information on the drug product that is 

the subject of the application has been submitted to the FDA; (2) such patent has expired; (3) the date on which such patent expires; or (4) such patent is 
invalid or will not be infringed upon by the manufacture, use or sale of the drug product for which the application is submitted. Generally, the ANDA or 
505(b)(2) NDA cannot be approved until all listed patents have expired, except where the ANDA or 505(b)(2) NDA applicant challenges a listed patent 
through the last type of certification, also known as a paragraph IV certification. The filing of a patent infringement lawsuit within 45 days after the receipt 
of a Paragraph IV certification automatically prevents the FDA from approving the ANDA or 505(b)(2) NDA until the earliest of 30 months after the 
receipt of the Paragraph IV notice, expiration of the patent and a decision in the infringement case that is favorable to the ANDA or 505(b)(2) NDA 
applicant. If the applicant does not challenge the listed patents, or indicates that it is not seeking approval of a patented method of use, the ANDA or 505(b)
(2) NDA application will not be approved until all of the listed patents claiming the referenced product have expired. 

The FDA also cannot approve an ANDA or 505(b)(2) application until all applicable non-patent exclusivities listed in the Orange Book for the 
branded reference drug have expired. For example, a pharmaceutical manufacturer may obtain five years of non-patent exclusivity upon NDA approval of a 
new chemical entity, or NCE, which is a drug containing an active moiety that has not been approved by FDA in any other NDA. This interpretation was 
confirmed with enactment of the Ensuring Innovation Act in April 2021. An “active moiety” is defined as the molecule responsible for the drug substance’s 
physiological or pharmacologic action. During that five-year exclusivity period, the FDA cannot accept for filing (and therefore cannot approve) any 
ANDA seeking approval of a generic version of that drug or any 505(b)(2) NDA that relies on the FDA’s approval of the drug, provided that the FDA may 
accept an ANDA four years into the NCE exclusivity period if the ANDA applicant also files a paragraph IV certification. 

Pediatric Exclusivity

Pediatric exclusivity is a type of non‑patent marketing exclusivity in the United States and, if granted, provides for the attachment of an additional 

six months of exclusivity. For drug products, the six-month exclusivity may be attached to the term of any existing patent or regulatory exclusivity, 
including the orphan exclusivity and regulatory exclusivities available under the Drug Price Competition and Patent Term Restoration Act of 1984, or the 
Hatch-Waxman Act. For biologic products, the six-month period may be attached to any existing regulatory exclusivities but not to any patent terms. The 
conditions for pediatric exclusivity include the FDA’s determination that information relating to the use of a new product in the pediatric population may 
produce health benefits in that population, the FDA making a written request for pediatric clinical trials, and the sponsor agreeing to perform, and reporting 
on, the requested clinical trials within the statutory timeframe. This six‑month exclusivity may be granted if a sponsor submits pediatric data that fairly 
respond to a written request from the FDA for such data. The data do not need to show the product to be effective in the pediatric population studied; rather, 
if the clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. 

Patent Term Restoration and Extension

In the United States, a patent claiming a new product, its method of use or its method of manufacture may be eligible for a limited patent term 

extension under the Hatch‑Waxman Act, which permits a patent extension of up to five years for patent term lost during product development and FDA 
regulatory review. Assuming grant of the patent for which the extension is sought, the restoration period for a patent covering a product is typically 
one‑half the time between the effective date of the IND involving human beings and the submission date of the NDA or BLA, plus the time between the 
submission date of the application and the ultimate approval date. Patent term restoration cannot be used to extend the remaining term of a patent past a 
total of 14 years from the product’s approval date in the United States. Only one patent applicable to an approved product is eligible for the extension, and 
the application for the extension must be submitted prior to the expiration of the patent for which extension is sought. A patent that covers multiple 
products for which approval is sought can only be extended in connection with one of the approvals. The U.S. Patent and Trademark Office reviews and 
approves the application for any patent term extension in consultation with the FDA.

Federal and State Fraud and Abuse, and Transparency Laws and Regulations 

In addition to strict FDA regulation of marketing of biopharmaceutical products, federal and state healthcare laws strictly regulate business practices 

in the biopharmaceutical industry. These laws may impact, among other things, our current and future business operations, including our clinical research 
activities, and proposed sales, marketing and education programs and constrain the business or financial arrangements and relationships with healthcare 
providers and other parties through which we market, sell and distribute our products for which we obtain marketing approval. These laws include 

71

 
anti-kickback and false claims laws and regulations, and transparency laws and regulations, including, without limitation, those laws described below. 

The U.S. federal Anti-Kickback Statute prohibits any person or entity from, among other things, knowingly and willfully offering, paying, soliciting 
or receiving remuneration to induce or in return for purchasing, leasing, ordering or arranging for or recommending the purchase, lease or order of any item 
or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term “remuneration” has been broadly interpreted to include 
anything of value. The U.S. federal Anti-Kickback Statute has been interpreted to apply to, among others, arrangements between biopharmaceutical 
manufacturers on the one hand and prescribers, purchasers and formulary managers on the other. Although there are a number of statutory exceptions and 
regulatory safe harbors protecting some common arrangements and other activities from prosecution, the exceptions and safe harbors are drawn narrowly. 
Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if 
they do not qualify for an exception or safe harbor. Courts have interpreted the statute’s intent requirement to mean that if any one purpose of an 
arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statute has been violated. 

A person or entity does not need to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. In 

addition, the government may assert that a claim including items or services resulting from a violation of the U.S. federal Anti-Kickback Statute constitutes 
a false or fraudulent claim for purposes of the federal civil False Claims Act or the civil monetary penalties laws. 

Federal civil and criminal false claims laws, including the federal civil False Claims Act, which can be enforced by individuals through civil 

whistleblower and qui tam actions, and civil monetary penalties laws, prohibit any person or entity from, among other things, knowingly presenting, or 
causing to be presented, a false claim for payment to the federal government or knowingly making, using or causing to be made or used a false record or 
statement material to a false or fraudulent claim to the federal government. A claim includes “any request or demand” for money or property presented to 
the U.S. government. A number of biopharmaceutical and other healthcare companies have been prosecuted under these laws for allegedly providing 
payments or other items of value to customers with the expectation that the customers would bill federal programs for their products or services. Other 
companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of products for unapproved, and thus non-
reimbursable, uses. 

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created additional federal criminal statutes that prohibit, among 

other things, knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private third-party payors and knowingly 
and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the 
delivery of or payment for healthcare benefits, items or services. Also, many states have similar fraud and abuse statutes or regulations that apply to items 
and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor. 

The federal Physician Payments Sunshine Act requires certain manufacturers of drugs, devices, biologics and medical supplies for which payment is 
available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to report annually to the Centers for Medicare & 
Medicaid Services, or CMS, information related to payments or other transfers of value made to physicians (defined to include doctors, dentists, 
optometrists, podiatrists and chiropractors), and teaching hospitals, and applicable manufacturers and applicable group purchasing organizations to report 
annually to CMS ownership and investment interests held by physicians and their immediate family members. As of January 2022, applicable 
manufacturers are also required to report such information regarding its payments and other transfers of value to physician assistants, nurse practitioners, 
clinical nurse specialists, anesthesiologist assistants, certified registered nurse anesthetists and certified nurse midwives during the previous year.

We may also be subject to state laws that require biopharmaceutical companies to comply with the biopharmaceutical industry’s voluntary 
compliance guidelines and the relevant compliance guidance promulgated by the federal government, state laws that require drug manufacturers to report 
information related to payments and other transfers of value to physicians and other healthcare providers, marketing expenditures or drug pricing, and state 
and local laws that require the registration of biopharmaceutical sales representatives. 

Because of the breadth of these laws and the narrowness of available statutory exceptions and regulatory safe harbors, it is possible that some of our 
business activities could be subject to challenge under one or more of such laws. If our operations are found to be in violation of any of the federal and state 
laws described above or any other governmental regulations that apply to us, we may be subject to significant criminal, civil and administrative penalties 
including damages, fines, imprisonment, disgorgement, additional reporting requirements and oversight if we become subject to a corporate 

72

 
integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, contractual damages, reputational harm, diminished 
profits and future earnings, exclusion from participation in government healthcare programs and the curtailment or restructuring of our operations, any of 
which could adversely affect our ability to operate our business and our results of operations. To the extent that any of our products are sold in a foreign 
country, we may be subject to similar foreign laws and regulations, which may include, for instance, applicable post-marketing requirements, including 
safety surveillance, anti-fraud and abuse laws, implementation of corporate compliance programs, and reporting of payments or transfers of value to 
healthcare professionals. 

Coverage and Reimbursement 

The future commercial success of our product candidates, if approved, will depend in part on the extent to which third-party payors, such as 
governmental payor programs at the federal and state levels, including Medicare and Medicaid, private health insurers and other third-party payors, provide 
coverage of and establish adequate reimbursement levels for our product candidates. Third-party payors generally decide which products they will pay for 
and establish reimbursement levels for those products. In particular, in the United States, no uniform policy for coverage and reimbursement exists. Private 
health insurers and other third-party payors often provide coverage and reimbursement for products based on the level at which the government, through 
the Medicare program, provides coverage and reimbursement for such products, but also on their own methods and approval process apart from Medicare 
determinations. Therefore, coverage and reimbursement can differ significantly from payor to payor. 

In the United States, the EU and other potentially significant markets for our product candidates, government authorities and third-party payors are 
increasingly attempting to limit or regulate the price of products, particularly for new and innovative products, which often has resulted in average selling 
prices lower than they would otherwise be. Further, the increased emphasis on managed healthcare in the United States and on country and regional pricing 
and reimbursement controls in the EU will put additional pressure on product pricing, reimbursement and usage. These pressures can arise from rules and 
practices of managed care groups, judicial decisions and laws and regulations related to Medicare, Medicaid and healthcare reform, biopharmaceutical 
coverage and reimbursement policies and pricing in general. 

Third-party payors are increasingly imposing additional requirements and restrictions on coverage and limiting reimbursement levels for products. 

For example, federal and state governments reimburse products at varying rates generally below average wholesale price. These restrictions and limitations 
influence the purchase of products. Third-party payors may limit coverage to specific products on an approved list, or formulary, which might not include 
all of the FDA-approved products for a particular indication. Similarly, because certain of our product candidates are physician-administered, separate 
reimbursement for the product itself may or may not be available. Instead, the administering physician may only be reimbursed for providing the treatment 
or procedure in which our product is used. Third-party payors are increasingly challenging the price and examining the medical necessity and cost-
effectiveness of products, in addition to their safety and efficacy. We may need to conduct expensive pharmacoeconomic trials in order to demonstrate the 
medical necessity and cost-effectiveness of our product candidates, in addition to the costs required to obtain the FDA approvals. Our product candidates 
may not be considered medically necessary or cost-effective. A payor’s decision to provide coverage for a product does not imply that an adequate 
reimbursement rate will be approved. Adequate third-party payor reimbursement may not be available to enable us to realize an appropriate return on our 
investment in product development. Legislative proposals to reform healthcare or reduce costs under government insurance programs may result in lower 
reimbursement for our product candidates, if approved, or exclusion of our product candidates from coverage and reimbursement. The cost containment 
measures that third-party payors and providers are instituting and any healthcare reform could significantly reduce our revenue from the sale of any 
approved product candidates. 

Healthcare Reform 

The United States and some foreign jurisdictions are considering enacting or have enacted a number of additional legislative and regulatory 
proposals to change the healthcare system in ways that could affect our ability to sell our product candidates profitably, if approved. Among policy makers 
and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing 
healthcare costs, improving quality and expanding access. In the United States, the biopharmaceutical industry has been a particular focus of these efforts, 
which include major legislative initiatives to reduce the cost of care through changes in the healthcare system, including limits on the pricing, coverage, and 
reimbursement of biopharmaceutical products, especially under government-funded healthcare programs, and increased governmental control of drug 
pricing. 

There have been several U.S. government initiatives over the past few years to fund and incentivize certain comparative effectiveness research, 

including creation of the Patient-Centered Outcomes Research Institute under the ACA. 

73

 
It is also possible that comparative effectiveness research demonstrating benefits in a competitor’s product could adversely affect the sales of our product 
candidates. 

The ACA became law in March 2010 and substantially changed the way healthcare is financed by third-party payors, and significantly impacts the 

U.S. biopharmaceutical industry. Among other measures that may have an impact on our business, the ACA established an annual, nondeductible fee on 
any entity that manufactures or imports specified branded prescription drugs and biologic agents; a new Medicare Part D coverage gap discount program; 
and a new formula that increased the rebates a manufacturer must pay under the Medicaid Drug Rebate Program. Additionally, the ACA extended 
manufacturers’ Medicaid rebate liability, expands eligibility criteria for Medicaid programs, and expanded entities eligible for discounts under the PHSA. 
At this time, we are unsure of the full impact that the ACA will have on our business. 

In March 2010, the United States Congress enacted the ACA, which, among other things, includes changes to the coverage and payment for 
pharmaceutical products under government healthcare programs. Other legislative changes have been proposed and adopted since the ACA was enacted. In 
August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on 
Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach 
required goals, thereby triggering the legislation’s automatic reduction to several government programs. These changes included aggregate reductions to 
Medicare payments to providers of up to 2% per fiscal year, which went into effect in April 2013 and will remain in effect through 2031. Pursuant to the 
Coronavirus Aid, Relief and Economic Security Act, or CARES Act, and subsequent legislation, these Medicare sequester reductions have been suspended 
through the end of March 2022. From April 2022 through June 2022 a 1% sequester cut will be in effect, with the full 2% cut resuming thereafter.

Since enactment of the ACA, there have been, and continue to be, numerous legal challenges and Congressional actions to repeal and replace 
provisions of the law. For example, with enactment of the Tax Cuts and Jobs Act of 2017, or the Tax Act, which was signed by President Trump on 
December 22, 2017, Congress repealed the “individual mandate.” The repeal of this provision, which requires most Americans to carry a minimal level of 
health insurance, became effective in 2019. On December 14, 2018, a U.S. District Court judge in the Northern District of Texas ruled that the individual 
mandate portion of the ACA is an essential and inseverable feature of the ACA, and therefore because the mandate was repealed as part of the Tax Act, the 
remaining provisions of the ACA are invalid as well. The U.S. Supreme Court heard this case on November 10, 2020 and, on June 17, 2021, dismissed this 
action after finding that the plaintiffs do not have standing to challenge the constitutionality of the ACA. Litigation and legislation over the ACA are likely 
to continue, with unpredictable and uncertain results.

The prices of prescription pharmaceuticals have also been the subject of considerable discussion in the United States. There have been several recent 

U.S. Congressional inquiries, as well as proposed and enacted state and federal legislation designed to, among other things, bring more transparency to 
pharmaceutical pricing, review the relationship between pricing and manufacturer patient programs, and reduce the costs of pharmaceuticals under 
Medicare and Medicaid. In 2020 President Trump issued several executive orders intended to lower the costs of prescription products and certain 
provisions in these orders have been incorporated into regulations. These regulations include an interim final rule implementing a most favored nation 
model for prices that would tie Medicare Part B payments for certain physician-administered pharmaceuticals to the lowest price paid in other 
economically advanced countries, effective January 1, 2021. That rule, however, has been subject to a nationwide preliminary injunction and, on December 
29, 2021, CMS issued a final rule to rescind it. With issuance of this rule, CMS stated that it will explore all options to incorporate value into payments for 
Medicare Part B pharmaceuticals and improve beneficiaries' access to evidence-based care.

In addition, in October 2020, HHS and the FDA published a final rule allowing states and other entities to develop a Section 804 Importation 
Program, or SIP, to import certain prescription drugs from Canada into the United States. The final rule is currently the subject of ongoing litigation, but at 
least six states (Vermont, Colorado, Florida, Maine, New Mexico, and New Hampshire) have passed laws allowing for the importation of drugs from 
Canada with the intent of developing SIPs for review and approval by the FDA. Further, on November 20, 2020, HHS finalized a regulation removing safe 
harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit 
managers, unless the price reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 2022 
to January 1, 2023 in response to ongoing litigation. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a 
new safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers, the implementation of which have also been 
delayed by the Biden administration until January 1, 2023.

At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control biopharmaceutical and 

biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost 
disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In addition, 
regional healthcare authorities and individual 

74

 
hospitals are increasingly using bidding procedures to determine which drugs and suppliers will be included in their healthcare programs. A number of 
states, for example, require drug manufacturers and other entities in the drug supply chain, including health carriers, pharmacy benefit managers, and 
wholesale distributors, to disclose information about pricing of pharmaceuticals. Furthermore, there has been increased interest by third party payors and 
governmental authorities in reference pricing systems and publication of discounts and list prices. These measures could reduce future demand for our 
products or put pressure on our pricing. 

Foreign Regulation 

In order to market any product outside of the United States, we would need to comply with numerous and varying regulatory requirements of other 

countries regarding safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of our 
product candidates. For example, in the EU, we must obtain authorization of a clinical trial application in each member state in which we intend to conduct 
a clinical trial. Whether or not we obtain FDA approval for a drug, we would need to obtain the necessary approvals by the comparable regulatory 
authorities of foreign countries before we can commence clinical trials or marketing of the drug in those countries. The approval process varies from 
country to country and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other 
countries might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country does not ensure regulatory 
approval in another, but a failure or delay in obtaining regulatory approval in one country may negatively impact the regulatory process in others. 

Further, some countries outside of the United States, including the EU member states, Switzerland and the U.K., have also adopted data protection 

laws and regulations, which impose significant compliance obligations. In the EU, the collection and use of personal health data is governed by the 
provisions of the General Data Protection Regulation, or GDPR. The GDPR, together with the national legislation of the EU member states governing the 
processing of personal data, impose strict obligations and restrictions on the ability to process personal data, including health data from clinical trials and 
adverse event reporting. For additional information regarding the GDPR, see the section titled “Business—Government Regulation and Product Approval
—Privacy Laws.”

Privacy Laws

We, and our service providers, receive, process, store and use personal information and other data about our clinical trial participants, employees, 

collaborators and others. We are subject to numerous domestic and foreign laws and regulations regarding privacy and data security, the scope of which is 
changing, subject to differing applications and interpretations, and may be inconsistent among countries, or conflict with other rules.

At the federal level, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their 

respective implementing regulations, impose specific requirements on certain types of individuals and entities relating to the privacy, security and 
transmission of individually identifiable health information. HITECH, among other things, also increased the civil and criminal penalties that may be 
imposed for non-compliance with the law, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to 
enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil actions. Penalties for failure to comply with a requirement of 
HIPAA and HITECH vary significantly, and include significant civil monetary penalties and, in certain circumstances, criminal penalties and/or 
imprisonment.

Various states, such as California and Massachusetts, have implemented privacy laws and regulations similar to HIPAA, such as the California 

Confidentiality of Medical Information Act, that impose restrictive requirements regulating the use and disclosure of health information. These laws and 
regulations are not necessarily preempted by HIPAA, particularly if a state affords greater protection to individuals than HIPAA. Where state laws are more 
protective, we have to comply with the stricter provisions. In addition to fines and penalties imposed upon violators, some of these state laws also afford 
private rights of action to individuals who believe their personal information has been misused. California’s patient privacy laws, for example, provide for 
penalties of up to $250,000 and permit injured parties to sue for damages. 

Additionally, the California Consumer Privacy Act, the CCPA, which took effect on January 1, 2020, gives California residents expanded rights to 

access and delete their personal information, opt out of certain personal information sharing, and receive detailed information about how their personal 
information is used. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches, which is expected to increase 
data breach litigation. The CCPA may increase our compliance costs and potential liability. It is anticipated that the CCPA will be expanded on January 1, 
2023, when the California Privacy Rights Act of 2020, the CPRA, becomes operative. The CPRA will, among other things, give California residents the 
ability to limit use of certain sensitive personal information, further restrict the use of 

75

 
cross-contextual advertising, establish restrictions on the retention of personal information, expand the types of data breaches subject to the CCPA’s private 
right of action, provide for increased penalties for CPRA violations concerning California residents under the age of 16, and establish a new California 
Privacy Protection Agency to implement and enforce the new law. Some observers have noted that the CCPA and CPRA could mark the beginning of a 
trend toward more stringent state privacy, data protection and data security legislation in the U.S., which could increase our potential liability and adversely 
affect our business. Furthermore, the interplay of federal laws—such as HIPAA—and state laws may be subject to varying interpretations by courts and 
government agencies, creating complex compliance issues for us and data we receive, use and share, potentially exposing us to additional expense, adverse 
publicity and liability.

Regulation of privacy, data protection and data security has also become more stringent in foreign jurisdictions. For example, the EU adopted the 

GDPR, which imposes onerous and comprehensive privacy, data protection, and data security obligations onto data controllers and processors, including, as 
applicable, contractual privacy, data protection, and data security commitments, expanded disclosures to data subjects about how their personal information 
is used, honoring individuals’ data protection rights, limitations on retention of personal information, additional requirements pertaining to sensitive 
information (such as health data) and pseudonymized (i.e., key-coded) data, data breach notification requirements, and higher standards for obtaining 
consent from data subjects. Penalties for non-compliance with the GDPR can be significant and include fines in the amount of the greater of €20 million or 
4% of global turnover and restrictions or prohibitions on data processing, which could hinder our ability to do business in the EU, reduce demand for our 
services and adversely impact our business and results of operations. The GDPR also provides that EU member states may implement further laws and 
regulations limiting the processing of genetic, biometric, or health data, which could limit our ability to collect, use and share European data, or could cause 
our compliance costs to increase, require us to change our practices, adversely impact our business, and harm our financial condition. Assisting parties with 
whom we exchange personal data in complying with the GDPR, or complying with the GDPR ourselves, may cause us to incur substantial operational 
costs or require us to change our business practices.

Furthermore, European privacy, data protection, and data security laws, including the GDPR, generally restrict the transfer of personal information 

from the U.K., European Economic Area, or EEA, and Switzerland to the United States and most other countries unless the parties to the transfer have 
implemented specific safeguards to protect the transferred personal information. There is uncertainty as to how to implement such safeguards and how to 
conduct such transfers in compliance with the GDPR, and certain safeguards may not be available or applicable with respect to some or all of the personal 
information processing activities necessary to research, develop and market our products and services. One of the primary safeguards allowing U.S. 
companies to import personal information from Europe has been certification to the EU-U.S. Privacy Shield and Swiss-U.S. Privacy Shield frameworks. 
However, the EU-U.S. Privacy Shield framework was invalidated in July 2020 in a decision by the Court of Justice of the European Union and the Swiss-
U.S. Privacy Shield Framework was declared as inadequate by the Swiss Federal Data Protection and Information Commissioner. The decision by the 
Court of Justice and the announcement by the Swiss Commissioner both raised questions about whether one of the primary alternatives to the Privacy 
Shield frameworks, the European Commission’s Standard Contractual Clauses, can lawfully be used for personal information transfers from Europe to the 
United States or most other countries. Authorities in the U.K. may similarly invalidate use of the EU-U.S. Privacy Shield and raise questions on the 
viability of the Standard Contractual Clauses. In November 2020, EU regulators proposed a new set of Standard Contractual Clauses, which impose 
additional obligations and requirements with respect to the transfer of EU personal data to other jurisdictions, which may increase the legal risks and 
liabilities under the GDPR and local EU laws associated with cross-border data transfers, and result in material increased compliance and operational costs. 
If we are unable to implement a valid mechanism for personal information transfers to the United States and other countries, we may face increased 
exposure to regulatory actions, substantial fines, and injunctions against processing or transferring personal information from Europe, and we may be 
required to increase our data processing capabilities in Europe at significant expense. Inability to import personal information from Europe to the United 
States or other countries may limit our ability to conduct clinical trials in Europe and collaborate with other entities subject to European data protection 
laws. At present, there are few, if any, viable alternatives to the Privacy Shield and the Standard Contractual Clauses. Other countries outside of Europe 
have enacted or are considering enacting similar cross-border data transfer restrictions and laws requiring local data residency, which could increase the 
cost and complexity of delivering our services and operating our business. 

76

 
In addition, it is unclear whether the transfer of personal information from the EU to the U.K. will continue to remain lawful under the GDPR in 

light of Brexit. Pursuant to a post-Brexit trade deal between the U.K. and the EU, transfers of personal information from the EEA to the U.K. are not 
considered restricted transfers under the GDPR for a period of up to four months from January 1, 2021 with a potential two-month extension. However, 
unless the EU Commission makes an adequacy finding with respect to the U.K. before the end of that period, the U.K. will be considered a “third country” 
under the GDPR and transfers of European personal information to the U.K. will require an adequacy mechanism to render such transfers lawful under the 
GDPR. Additionally, although U.K. privacy, data protection and data security laws are designed to be consistent with the GDPR, uncertainty remains 
regarding how data transfers to and from the U.K. will be regulated notwithstanding Brexit.

Compliance with U.S. and foreign privacy, data protection, and data security laws and regulations could cause us to incur substantial costs or require 

us to change our business practices and compliance procedures in a manner adverse to our business. Moreover, complying with these various laws could 
require us to take on more onerous obligations in our contracts, restrict our ability to collect, use and disclose data, or in some cases, impact our ability to 
operate in certain jurisdictions. We may rely on others, such as health care providers, to obtain valid and appropriate consents from data subjects whose 
data we process. The failure of third parties to obtain consents that are valid under applicable law could result in our own non-compliance with privacy 
laws. Such failure to comply with U.S. and foreign privacy, data protection, and data security laws and regulations could result in government enforcement 
actions (which could include civil or criminal penalties), private litigation and/or adverse publicity and could negatively affect our operating results and 
business. Claims that we have violated individuals’ privacy rights, failed to comply with privacy, data protection, and data security laws, or breached our 
contractual obligations, even if we are not found liable, could be expensive and time consuming to defend, could result in adverse publicity and could have 
a material adverse effect on our business, financial condition, and results of operations.

Legal Proceedings 

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not 

currently a party to any material legal proceedings. Regardless of outcome, such proceedings or claims can have an adverse impact on us because of 
defense and settlement costs, diversion of resources and other factors, and there can be no assurances that favorable outcomes will be obtained. 

Human Capital Management 

Employees 

As of December 31, 2021, we had 444 full-time employees, 318 of whom were primarily engaged in research and development activities. 
Substantially all of our employees are located in San Francisco, California; Portland, Oregon; and Bellinzona, Switzerland. None of our employees are 
represented by a labor union and we consider our employee relations to be good. 

As the clinical development of our product candidates progresses, we expect to continue to experience significant growth in the number of our 
employees and the scope of our operations, particularly in the areas of research, development, regulatory affairs and, if any of our product candidates 
receives marketing approval, sales, marketing and distribution. In addition, we also expect to hire additional personnel in order to sustain operations as a 
public company.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and 

additional employees. The principal purpose of our equity incentive plan is to attract, retain, and motivate our employees, non-employee directors, and 
consultants through the granting of stock-based compensation and performance cash awards. 

77

 
Response to COVID-19

With the global spread of the current COVID-19 pandemic, we have implemented a number of plans and policies designed to address and mitigate 

the impact of the COVID-19 pandemic on our employees and our business. We continue to closely monitor the COVID-19 situation and will evolve our 
plans and policies as needed going forward. As a result of these developments, in March 2020, we implemented work-from-home policies for most of our 
employees. We have also implemented plans, which continue to evolve based on the current climate and response to the ongoing COVID-19 pandemic, to 
reopen our offices to allow employees to return when appropriate. Although these plans are based on a phased approach consistent with local government 
requirements, and focused on employee safety, and contemplate returning to remote work should new restrictions be implemented, there is uncertainty 
regarding recent phased reopening, which may be rolled back, and restrictions re-implemented. We are also working to provide our employees with the 
support they need to ensure continuity of business operations.

Item 1A. Risk Factors.

An investment in shares of our common stock involves a high degree of risk. You should carefully consider the following risk factors as well as the 

other information in this Annual Report on Form 10-K, including our audited consolidated financial statements and the related notes included elsewhere in 
this Annual Report on Form 10-K and “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, before deciding 
whether to invest in our common stock. The occurrence of any of the events or developments described below could harm our business, financial condition, 
results of operations and/or prospects or cause our actual results to differ materially from those contained in forward-looking statements we have made in 
this report and those we may make from time to time. In such an event, the market price of our common stock could decline and you may lose all or part of 
your investment. You should consider all of the risk factors described when evaluating our business. 

Risks Related to Our Financial Position and Capital Needs 

We have incurred net losses and anticipate that we may continue to incur net losses in the foreseeable future and therefore, may not be able to maintain 
profitability. 

Although we recorded net income for the year ended December 31, 2021, we have otherwise incurred accumulated net losses since inception in 

April 2016. We had net income of $528.6 million for the year ended December 31, 2021, and net loss of $298.7 million and $174.7 million for the years 
ended December 31, 2020 and 2019, respectively. As of December 31, 2021, we had an accumulated deficit of $138.6 million. 

We expect to continue to incur significant expenses and may continue to incur net losses in the foreseeable future. Since inception, we have devoted 

substantially all of our efforts to identifying, researching and conducting preclinical and clinical activities of our product candidates, acquiring and 
developing our technology platforms and product candidates, organizing and staffing our company, business planning, raising capital and establishing our 
intellectual property portfolio. We have received an Emergency Use Authorization, or EUA, from the U.S. Food and Drug Administration, or FDA, and a 
positive scientific opinion from the Committee for Human Medicinal Products, or CHMP, in the European Union, or EU, for sotrovimab (previously VIR-
7831). To date, sotrovimab has been granted EUA, temporary authorization or marketing approval (under the brand name Xevudy®) in more than 40 
countries. Although we (through our collaborator Glaxo Wellcome UK Limited and GlaxoSmithKline Biologicals S.A. (individually and collectively 
referred to as GSK)) have recently entered into procurement agreements to supply sotrovimab to governments around the world and began to recognize 
revenue for sotrovimab, the extent of future revenue remains uncertain. However, there are no assurances that we will secure additional supply 
commitments from governments. In addition, COVID-19 treatment standards are susceptible to rapid changes in epidemiology and the emergence of new 
variants, thus, sotrovimab may be rendered inferior or obsolete in the future. It could be several years, if ever, before we are able to commercialize any of 
our other product candidates. Any net losses we incur may fluctuate significantly from quarter to quarter and year to year. To remain profitable, we must 
succeed in developing and eventually commercializing products that generate significant revenue. This will require us to be successful in a range of 
challenging activities, including completing preclinical studies and clinical trials of our current and future product candidates, obtaining regulatory 
approval, procuring commercial-scale manufacturing, marketing and selling any products for which we obtain regulatory approval (including through third 
parties), as well as discovering or acquiring and developing additional product candidates. We are only in the preliminary stages of most of these activities. 
We may never succeed in these activities and, even if we do, may not be able to continue to generate revenue that is sufficient to offset our expenses and 
maintain profitability. 

Because of the numerous risks and uncertainties associated with biopharmaceutical product development, we are unable to accurately predict the 
timing or amount of expenses, or if, we will be able to maintain profitability. If we are required by regulatory authorities to perform studies and trials in 
addition to those currently expected, or if there are any delays in the initiation and completion of our clinical trials or the development of any of our product 
candidates, our expenses could increase. For example, the FDA has asked for additional data to support our conclusion that the 500 mg IV dose of 
sotrovimab retains activity against the BA.2 Omicron subvariant based on our current modeling assumptions as well as safety data for higher doses. We 
could be required to perform additional studies and trials on sotrovimab based on any additional feedback we may receive from the FDA.

We may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to remain profitable would decrease the value of 
our company and could impair our ability to raise capital, maintain our research and development efforts, expand our business or continue our operations. 

79

 
 
 
Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability. 

We are a commercial-stage company founded in April 2016 and our operations to date have been largely focused on identifying, researching and 

conducting preclinical and clinical activities of our product candidates, acquiring and developing our technology platforms and product candidates, 
organizing and staffing our company, business planning, raising capital and establishing our intellectual property portfolio. Sotrovimab has received an 
EUA from the FDA and marketing authorization in the EU. To date, sotrovimab has been granted EUA, temporary authorization or marketing approval 
(under the brand name Xevudy®) in more than 40 countries. We are in the early stages of seeking approval under a biologics license application, or BLA, 
and expanding our commercialization capabilities for sotrovimab. As an organization, we have not yet demonstrated an ability to successfully manufacture 
a BLA-approved, commercial-scale product or conduct sales and marketing activities necessary for successful commercialization. Consequently, any 
predictions about our future success or viability may not be as accurate as they could be if we had a longer operating history. 

We currently have four technology platforms and eight product candidates in our development pipeline. We may encounter unforeseen expenses, 

difficulties, complications, delays and other known or unknown factors in achieving our business objectives, including with respect to our technology 
platforms and product candidates.

We may require substantial additional funding to finance our operations. If we are unable to raise capital when needed, we could be forced to delay, 
reduce or terminate certain of our development programs or other operations. 

As of December 31, 2021, excluding restricted cash, we had cash, cash equivalents and investments of $909.5 million and by also excluding the 

equity investment in Brii Biosciences Limited, or Brii Bio Parent, we had $766.4 million. Based upon our current operating plan, we believe that the 
$766.4 million as of December 31, 2021 will fund our current operating plans for at least the next 12 months. However, our operating plan may change as a 
result of many factors currently unknown to us, and we may need to seek additional financing to fund our long-term operations sooner than planned. 
Moreover, it is particularly difficult to estimate with certainty our future expenses given the dynamic and rapidly evolving nature of our business and the 
COVID-19 pandemic environment generally. We may also need to raise additional capital to complete the development and commercialization of our EUA 
product or our product candidates and fund certain of our existing manufacturing and other commitments. We expect to finance our cash needs through 
public or private equity or debt financings, third-party (including government) funding and marketing and distribution arrangements, as well as other 
collaborations, strategic alliances and licensing arrangements, or any combination of these approaches. Our future capital requirements will depend on 
many factors, including: 

•

•

•

•

•

•

•

•

•

•

the timing, progress and results of our ongoing preclinical studies and clinical trials of our EUA product and other product candidates; 

the scope, progress, results and costs of preclinical development, laboratory testing and clinical trials of other product candidates that we may 
pursue;  

our ability to establish and maintain collaboration, license, grant and other similar arrangements, and the financial terms of any such 
arrangements, including timing and amount of any future milestones, royalty or other payments due thereunder; 

the costs, timing and outcome of regulatory review of our EUA product and other product candidates; 

the costs and timing of commercialization activities, including product manufacturing, marketing, sales and distribution, for our EUA product 
and any of our product candidates for which we receive marketing approval; 

the amount of revenue received from commercial sales of our EUA product or any product candidates for which we receive marketing 
approval; 

the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and 
defending any intellectual property-related claims; 

any expenses needed to attract, hire and retain skilled personnel; 

the costs of operating as a public company; and 

the extent to which we acquire or in-license other companies’ product candidates and technologies. 

The COVID-19 pandemic and the evolution of new and existing variants of COVID-19 have resulted in a significant disruption of global financial 

markets. If the disruption persists and deepens, we could experience an inability to access 

80

 
additional capital, which could in the future negatively affect our capacity for certain corporate development transactions or our ability to make other 
important, opportunistic investments. In addition, market volatility, inflation and interest rate fluctuations may increase our cost of financing or restrict our 
access to potential sources of future liquidity. Adequate additional financing may not be available to us on acceptable terms, or at all. If we are unable to 
raise capital when needed or on attractive terms, we could be forced to delay, reduce or altogether terminate our research and development programs or 
commercialization efforts, which may adversely affect our business, financial condition, results of operations and prospects. In addition, we may seek 
additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future 
operating plans. 

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our product candidates. 

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through public or private equity or debt 
financings, third-party (including government) funding and marketing and distribution arrangements, as well as other collaborations, strategic alliances and 
licensing arrangements, or any combination of these approaches. To the extent that we raise additional capital through the sale of equity or convertible debt 
securities, your ownership interest in our company may be diluted and the terms of these securities may include liquidation or other preferences that 
adversely affect your rights as a stockholder. Debt and equity financings, if available, may involve agreements that include covenants limiting or restricting 
our ability to take specific actions, such as redeeming our shares, making investments, incurring additional debt, making capital expenditures, declaring 
dividends or placing limitations on our ability to acquire, sell or license intellectual property rights. 

If we raise additional capital through future collaborations, strategic alliances or licensing arrangements, we may have to relinquish valuable rights 
to our intellectual property, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If 
we are unable to raise additional capital when needed, we may be required to delay, limit, reduce or terminate our product development or 
commercialization efforts or grant rights to develop and market product candidates that we would otherwise develop and market ourselves.

We received an EUA from the FDA for sotrovimab. If the FDA revokes or terminates our EUA for sotrovimab for the early treatment of COVID-19, the 
disease caused by the virus SARS-CoV-2, or the federally-declared COVID-19 public health emergency ends, we will be required to stop commercial 
distribution of sotrovimab in the United States unless we can obtain FDA approval for this product and its currently authorized uses.

Sotrovimab is currently made available pursuant to an EUA we received from the FDA on May 26, 2021 for the early treatment of mild to moderate 
COVID-19 in adults and pediatric patients (12 years of age and older weighing at least 40 kg) with positive results of direct SARS-CoV-2 viral testing, and 
who are at risk for progression to severe COVID-19, including hospitalization or death. The FDA will periodically review the circumstances and 
appropriateness of an EUA, including circumstances that might warrant revocation of the EUA. The review will include regular assessment based on 
additional information provided by the sponsor of the progress made with respect to the approval, licensure, or clearance of the unapproved product, or of 
the unapproved use of an approved product, for which an EUA was issued. The FDA may revise or revoke an EUA if the circumstances justifying its 
issuance no longer exist, the criteria for its issuance are no longer met, or other circumstances make a revision or revocation appropriate to protect the 
public health or safety. Such circumstances may include significant adverse inspectional findings; reports of adverse events linked to, or suspected of being 
caused by, the EUA product; a material change in the risk/benefit assessment based on evolving understanding of the disease or condition and/or 
availability of authorized medical products; or a change in the approval status of the product may make an EUA unnecessary. An EUA may also be 
terminated upon a declaration by the Secretary of the Health and Human Services, or HHS, that the public health emergency has ended. We cannot predict 
how long our EUA will remain in effect, and we may not receive advance notice from the FDA regarding revocation of our EUA or withdrawal of the 
public health emergency declaration. If our EUA is terminated or revoked, sotrovimab will no longer be available in the United States unless and until we 
have obtained FDA approval of a BLA for the product. Changing policies and regulatory requirements could limit, delay or prevent further 
commercialization of sotrovimab and could adversely impact our business, financial condition, results of operations and prospects. 

We are committing substantial financial resources and personnel and making substantial capital commitments with third parties in connection with 
sotrovimab as a therapy for COVID-19. Market demand and utilization of sotrovimab or any of our other COVID-19 product candidates may be 
adversely impacted by factors such as the development of monoclonal antibodies, or mAbs, of other third parties, the rollout of vaccines and oral 
antivirals, the emergence of new viral variants, and the current challenges in the delivery and administration of mAbs to patients. 

81

 
 
In response to the ongoing COVID-19 pandemic, we are pursuing various potential therapies to address the disease, including through mAbs using 

our antibody platform (in collaboration with several partners), such as sotrovimab and VIR-7832. Sotrovimab has received an EUA from the FDA and 
marketing authorization in the EU. To date, sotrovimab has been granted EUA, temporary authorization or marketing approval (under the brand name 
Xevudy®) in more than 40 countries. Also, we (through our collaborator GSK) have recently entered into procurement agreements to supply sotrovimab to 
governments around the world; however, there are no assurances that we will secure additional supply commitments from governments. We have not 
received regulatory approval for any of our other product candidates.

We are committing substantial financial resources, both internally and externally, and personnel to the development of a therapy for COVID-19, 
which may cause delays in or otherwise negatively impact our other development programs. There are no assurances that there will be sufficient market 
demand for sotrovimab or our other COVID-19 product candidates. Market demand and utilization of sotrovimab or any of our other COVID-19 product 
candidates may be adversely impacted by factors such as the development of mAbs of other third parties, the rollout of vaccines and oral antivirals, the 
emergence of new viral variants, and the current challenges in the delivery and administration of mAbs to patients. In addition, COVID-19 treatment 
standards are susceptible to rapid changes in epidemiology and the emergence of new variants, thus, sotrovimab may be rendered inferior or obsolete in the 
future, even if it were to gain widespread market acceptance initially. If sotrovimab is rendered inferior or obsolete in the future, our financial condition and 
business may be adversely affected.

Our ability to develop a successful therapy will also depend on the success of our manufacturing capabilities, for which we are dependent on third-
party manufacturing organizations and which will require significant additional funding. Our current estimated aggregate commitments to GSK under two 
separate master services agreements with Samsung Biologics Co., Ltd. and WuXi Biologics (Hong Kong) Limited, or WuXi Biologics, for drug substance, 
drug product and raw material were approximately $188 million as of December 31, 2021. For additional information regarding our obligations under these 
agreements, see the section titled “Business—Our Collaboration, License and Grant Agreements” and “Business—Manufacturing—Manufacturing 
Agreements.”

While we believe securing such manufacturing capacity and technological expertise is essential to the potential success of our SARS-CoV-2 
antibody development programs, such capital commitments plus any future commitments, in the aggregate, may, in the future, exceed our available cash 
and cash equivalents and investments. We may also need to enter into additional manufacturing arrangements in the future in order to create an effective 
supply chain for sotrovimab and our other COVID-19 product candidates that will adequately support demand. In the event that there is not enough 
demand for the manufacturing capacity that we have already secured or regulatory approval of our product candidates is delayed or unsuccessful, we may 
remain obligated to pay for such excess manufacturing capacity, which could adversely affect our business, financial condition, results of operations and 
prospects. We will need to raise substantial additional capital to fund the development of sotrovimab and our other product candidates and meet our capital 
commitments to our manufacturing partners in connection therewith. There can be no assurance that sufficient funds will be available to us on attractive 
terms or at all and our ability to obtain additional capital could be adversely affected if there is a significant decline in the demand for our products or other 
significantly unfavorable changes in economic conditions. If we are unable to obtain additional funding from these or other sources, it may be necessary to 
significantly reduce our rate of spending through reductions in staff and delaying, scaling back, or stopping certain research and development programs. 
Insufficient liquidity may also require us to relinquish rights to product candidates at an earlier stage of development or on less favorable terms than we 
would otherwise choose. Our business could be negatively impacted by our allocation of significant resources to a global health threat that is unpredictable 
or against which our potential therapies, if developed, may not be partially or fully effective, and may ultimately prove unsuccessful or unprofitable. 
Furthermore, there are no assurances that we will secure additional supply commitments from governments, which may be material to the commercial 
success of sotrovimab and our product candidates, either in the United States or abroad.

There are also efforts by other companies in developing prophylactic vaccines against COVID-19. For example, in August 2021 Pfizer Inc.’s, or 

Pfizer, COVID-19 vaccine, Comirnaty®, which has been proven to be 95% effective in clinical trials, was approved by the FDA for individuals 16 years of 
age or older and is also available under EUA for individuals 12 through 15 years of age. In January 2022, Moderna, Inc.'s vaccine, Spikevax®, which has 
proven to be 94% effective in clinical trials, was approved by the FDA for individuals 18 years of age or older. In addition, in February 2021 Janssen 
Biotech, Inc. received EUA from the FDA for its COVID-19 vaccine, which has been proven to be 85% effective in clinical trials. These other entities may 
be more successful at developing, manufacturing or commercializing a therapy for COVID-19. Several of these other organizations are much larger than 
we are and have access to larger pools of capital, including U.S. government funding, and broader manufacturing infrastructure. There are no assurances 
that there will be sufficient market demand for our COVID-19 therapies, that we will secure U.S. government funding, that our manufacturing and supply 
chain infrastructure will remain uninterrupted and reliable, or that the third parties we rely on to manufacture our COVID-19 

82

 
therapies will be able to satisfy demand in a timely manner and not have supply chain disruptions due to COVID-19 related shutdowns, stock-outs due to 
raw material shortages and/or greater than anticipated demand or quality issues given the operational challenges and raw material shortages that have been 
experienced during the COVID-19 pandemic, all of which may adversely impact our ability to commercialize a therapy for COVID-19. In addition, several 
organizations have already secured significant commitments from governments to purchase COVID-19 antibodies, oral antivirals, and vaccines. The 
success or failure of other entities, or perceived success or failure, may adversely impact our ability to obtain any future funding for our development and 
manufacturing efforts or to successfully commercialize a therapy for COVID-19. Additionally, the availability of superior or competitive therapies, or 
preventative measures such as vaccines or oral antivirals, coupled with the transient nature of pandemics, could negatively impact or eliminate demand for 
our COVID-19 therapies. For additional information regarding our competition see the section below titled “—Risks Related to the Development and 
Commercialization — We face substantial competition, which may result in others developing or commercializing products before or more successfully 
than us.”

Our near-term success is dependent on the successful commercialization of sotrovimab for the early treatment of COVID-19, including our ability to 
enter into additional procurement contracts with government entities. If we are unable to successfully commercialize sotrovimab, our business, 
financial condition, results of operations and prospects may be adversely affected. In addition, sotrovimab may be rendered inferior or obsolete, even if 
it were to gain widespread market acceptance initially. 

Our near-term success is dependent on the successful commercialization of sotrovimab, which is our only currently available commercial product. 

The commercial success of sotrovimab will depend on a number of factors, some of which are outside of our control, including the following:  

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

our ability to comply with all regulatory requirements applicable to our EUA, including applicable FDA marketing, manufacturing and post-
market requirements and other requirements of our EUA;

whether we are required by the FDA or other similar regulatory authorities to conduct additional clinical trials or to modify the design of our 
current trials to support the approval of sotrovimab;

the receipt of additional marketing authorizations and approvals from the FDA and other similar regulatory authorities;

our ability to achieve and maintain compliance with all regulatory requirements applicable to sotrovimab;

perceptions by the public and members of the medical community, including physicians, as to the safety and efficacy of sotrovimab as well as 
the accuracy and sufficiency of clinical evidence supporting its performance;

demand from the public and members of the medical community for sotrovimab;

the availability, perceived advantages, relative cost, relative convenience and relative efficacy of sotrovimab compared to other COVID-19 
therapies as well as the accuracy and sufficiency of clinical evidence supporting its performance;

the ability of sotrovimab to be effective in patients with COVID-19 and its variants;

positive or negative media coverage of sotrovimab;

the effectiveness of our marketing and sales efforts;

our ability to raise additional capital on acceptable terms, or at all, if needed to support the commercialization of sotrovimab;

the ability to enter into additional procurement contracts with government entities, and our ability to meet our obligations under such 
contracts;

our reliance on GSK and other collaborators for development, commercialization and manufacturing of sotrovimab; 

our ability to obtain, maintain and enforce our intellectual property rights;

our ability to maintain a continued supply of sotrovimab that meets our quality control requirements;

the ability of third-party manufacturing partners to meet demand in a timely manner, in accordance with our specifications, and in 
compliance with applicable regulatory requirements;

83

 
 
•

•

•

limitation on use or warnings required by the FDA; 

our current and future arrangements with healthcare providers, physicians and third-party payors; and 

availability of, or changes in, coverage or reimbursement rates for sotrovimab from government or other commercial or healthcare payors.

In addition, COVID-19 treatment standards are susceptible to rapid changes in epidemiology and the emergence of new variants, thus, sotrovimab 

may be rendered inferior or obsolete, even if it were to gain widespread market acceptance initially. Initial feedback from the FDA question our conclusion 
that the 500 mg IV dose of sotrovimab retains activity against the BA.2 Omicron subvariant based on our current modeling assumptions, and the FDA has 
asked for additional data to support our position. The FDA also requested safety data for higher doses. Both have been provided to the FDA and we are 
awaiting further correspondence. We could be required to perform additional studies and trials on sotrovimab based on any additional feedback we may 
receive from the FDA or the FDA could amend the terms of our EUA to limit the circumstances under which sotrovimab could be used as an early 
treatment for COVID-19.

If we are unable to successfully commercialize sotrovimab, our business, financial condition, results of operations and prospects may be adversely 

affected. 

Risks Related to the Development and Commercialization

Our future success is substantially dependent on the successful clinical development, regulatory approval and commercialization of our EUA product 
and product candidates in a timely manner. If we are not able to obtain required regulatory approvals, we will not be able to commercialize our product 
candidates and our ability to generate product revenue will be adversely affected. 

We have invested a significant portion of our time and financial resources in the development of our product candidates. Our business is dependent 

on our ability to successfully complete development of, obtain regulatory approval for, and successfully commercialize our EUA product and other product 
candidates, if approved, in a timely manner. We may face unforeseen challenges in our product development strategy, and we can provide no assurances 
that our product candidates will be successful in clinical trials or will ultimately receive regulatory approval. 

We initiated clinical trials for multiple product candidates. Sotrovimab has received an EUA from the FDA and marketing authorization in the EU. 

To date, sotrovimab has been granted EUA, temporary authorization or marketing approval (under the brand name Xevudy®) in more than 40 countries. 
The FDA may, under certain circumstances, revise or revoke an EUA. If our EUA is terminated or revoked, sotrovimab will no longer be available in the 
United States unless and until we have obtained FDA approval of a BLA for the product. We have not obtained BLA approval for sotrovimab or any other 
product candidate to date. We operate in a highly regulated field, and it is possible that any product candidate we may seek to develop in the future will not 
obtain regulatory approval. 

Prior to obtaining approval to commercialize any product candidate in the United States or abroad, we must demonstrate with substantial evidence 
from well-controlled clinical trials, and to the satisfaction of the FDA or comparable foreign regulatory authorities, that such product candidate is safe and 
effective for its intended uses. Results from preclinical studies and clinical trials can be interpreted in different ways. Even if we believe that the preclinical 
or clinical data for our product candidates are promising, such data may not be sufficient to support approval for further development, manufacturing or 
commercialization of our product candidates by the FDA and other regulatory authorities. The FDA may also require us to conduct additional preclinical 
studies or clinical trials for our product candidates either prior to or post-approval, or it may object to elements of our clinical development program, 
requiring their alteration. 

Even if we eventually complete clinical testing and receive approval of a new drug application, or NDA, BLA, or foreign marketing application for 

our product candidates, the FDA or the comparable foreign regulatory authorities may grant approval or other marketing authorization contingent on the 
performance of costly additional clinical trials, including post-market clinical trials. The FDA or the comparable foreign regulatory authorities also may 
approve or authorize for marketing a product candidate for a more limited indication or patient population than we originally request, and the FDA or 
comparable foreign regulatory authorities may not approve or authorize the labeling that we believe is necessary or desirable for the successful 
commercialization of a product candidate. Any delay in obtaining, or inability to obtain, applicable regulatory approval or other marketing authorization 
would delay or prevent commercialization of that product candidate and would adversely impact our business and prospects. 

84

 
 
In addition, the FDA or comparable foreign regulatory authorities may change their policies, adopt additional regulations or revise existing 
regulations or take other actions, which may prevent or delay approval of our future product candidates under development on a timely basis. Such policy 
or regulatory changes could impose additional requirements upon us that could delay our ability to obtain applicable regulatory approvals, increase the 
costs of compliance or restrict our ability to maintain any marketing authorizations we may have obtained. 

Furthermore, even if we obtain regulatory approval for our product candidates, we may still need to develop a commercial organization, establish a 

commercially viable pricing structure and obtain approval for coverage and adequate reimbursement from third-party and government payors, including 
government health administration authorities. If we are unable to successfully commercialize our product candidates or if there is an insufficient demand 
for our product candidates, we may not be able to generate sufficient revenue to continue our business. 

The development of additional product candidates is risky and uncertain, and we can provide no assurances that we will be able to replicate our 
approach for other diseases. 

A core element of our business strategy is to expand our product candidate pipeline. Efforts to identify, acquire or in-license, and then develop 
product candidates require substantial technical, financial and human resources, whether or not any product candidates are ultimately identified. Our efforts 
may initially show promise in identifying potential product candidates, yet fail to yield product candidates for clinical development, approved products or 
commercial revenue for many reasons. 

We have limited financial and management resources and, as a result, we may forego or delay pursuit of opportunities with other product candidates 

or for other indications that later prove to have greater market potential. Our resource allocation decisions may cause us to fail to capitalize on viable 
commercial products or profitable market opportunities. If we do not accurately evaluate the commercial potential or target market for a particular product 
candidate, we may relinquish valuable rights to that product candidate through collaboration, strategic alliances, licensing or other royalty arrangements in 
circumstances under which it would have been more advantageous for us to retain sole development and commercialization rights to such product 
candidate. In addition, we may not be successful in replicating our approach to development for other disease indications. If we are unsuccessful in 
identifying and developing additional product candidates or are unable to do so, our business may be harmed. 

We are developing, and in the future may develop, other product candidates in combination with other therapies, which exposes us to additional risks. 

We are developing VIR-2218 and VIR-3434 for the functional cure of hepatitis B virus, or HBV. Each of these product candidates has the potential 

to stimulate an effective immune response and also has direct antiviral activity against HBV. We believe that a functional cure for HBV will require an 
effective immune response, in addition to antiviral activity, based on the observation that severe immunosuppression can reactivate HBV disease. 
Monotherapy with each of these agents may provide a functional cure in some patients, while combination therapy may be necessary for others. We have 
an ongoing Phase 2 clinical trial that combines VIR-2218 with pegylated interferon-alpha and a Phase 2 clinical trial that combines VIR-2218 with VIR-
3434. We are also evaluating additional combinations with other immunotherapy agents and direct acting antiviral agents. Even if any product candidate we 
develop were to receive marketing approval or be commercialized for use in combination with other existing therapies, we would continue to be subject to 
the risks that the FDA or comparable foreign regulatory authorities could revoke approval of the therapy used in combination with our product candidate. 
There is also a risk that safety, efficacy, manufacturing or supply issues could arise with these other existing therapies. This could result in our own 
products being removed from the market or being less successful commercially. 

We may also evaluate our future product candidates in combination with one or more other therapies that have not yet been approved for marketing 

by the FDA or comparable foreign regulatory authorities. We will not be able to market any product candidate we develop in combination with any such 
unapproved therapies that do not ultimately obtain marketing approval. 

If the FDA or comparable foreign regulatory authorities do not approve these other drugs or revoke their approval of, or if safety, efficacy, 
manufacturing or supply issues arise with, the drugs we choose to evaluate in combination with any product candidate we develop, we may be unable to 
obtain approval. 

85

 
 
 
 
Success in preclinical studies or earlier clinical trials may not be indicative of results in future clinical trials and we cannot assure you that any 
ongoing, planned or future clinical trials will lead to results sufficient for the necessary regulatory approvals and market authorizations. 

Success in preclinical testing and earlier clinical trials does not ensure that later clinical trials will generate the same results or otherwise provide 
adequate data to demonstrate the efficacy and safety of a product candidate. Success in preclinical studies and earlier clinical trials does not ensure that 
later efficacy trials will be successful, nor does it predict final results. Our product candidates may fail to show the desired characteristics in clinical 
development sufficient to obtain regulatory approval, despite positive results in preclinical studies or having successfully advanced through earlier clinical 
trials. 

A trial design that is considered appropriate for regulatory approval includes a sufficiently large sample size with appropriate statistical power, as 

well as proper control of bias, to allow a meaningful interpretation of the results. If we do not conduct clinical trials with a large enough patient sample 
size, we may not achieve statistically significant results or the same level of statistical significance, if any, that would have been possible to achieve in a 
larger trial. 

As an organization, we have limited experience designing clinical trials and may be unable to design and execute a clinical trial to support 
regulatory approval, which could mean we will suffer setbacks. Any such setbacks could negatively impact our business, financial condition, results of 
operations and prospects. 

Interim, “top-line” and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data 
become available and are subject to audit and verification procedures that could result in material changes in the final data. 

From time to time, we may publish interim, “top-line” or preliminary data from our clinical trials. Interim data from clinical trials that we may 
complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data 
become available. Preliminary or “top-line” data also remain subject to audit and verification procedures that may result in the final data being materially 
different from the preliminary data we previously published. As a result, interim and preliminary data should be viewed with caution until the final data is 
available. Differences between preliminary or interim data and final data could significantly harm our business prospects and may cause the trading price of 
our common stock to fluctuate significantly. 

Clinical product development involves a lengthy and expensive process. We may incur additional costs and encounter substantial delays or difficulties 
in our clinical trials. 

We may not commercialize, market, promote or sell any product candidate without obtaining marketing approval from the FDA or comparable 
foreign regulatory authority, and we may never receive such approvals. It is impossible to predict when or if any of our product candidates will prove 
effective or safe in humans and will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of our 
product candidates, we must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy of our 
product candidates in humans. Clinical testing is expensive, is difficult to design and implement, can take many years to complete and is uncertain as to 
outcome. We cannot guarantee that any clinical trials will be conducted as planned or completed on schedule, if at all. A failure of one or more clinical 
trials can occur at any stage of testing. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many 
companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain 
marketing approval of their products. We may experience numerous unforeseen events prior to, during, or as a result of, clinical trials that could delay or 
prevent our ability to receive marketing approval or commercialize our product candidates. 

Any inability to successfully complete preclinical and clinical development could result in additional costs to us or impair our ability to generate 

revenue from future product sales or other sources. In addition, if we make manufacturing or formulation changes to our product candidates, we may need 
to conduct additional testing to bridge our modified product candidate to earlier versions. Clinical trial delays could also shorten any periods during which 
we may have the exclusive right to commercialize our product candidates, if approved, or allow our competitors to bring competing products to market 
before we do, which could impair our ability to successfully commercialize our product candidates and may harm our business, financial condition, results 
of operations and prospects. 

Additionally, if the results of our clinical trials are inconclusive or if there are safety concerns or serious adverse events associated with our product 

candidates, we may: 

86

 
 
 
•

•

•

•

•

•

•

•

•

be delayed in obtaining marketing approval, or not obtain marketing approval at all; 

obtain approval for indications or patient populations that are not as broad as intended or desired; 

obtain approval with labeling that includes significant use or distribution restrictions or safety warnings; 

be subject to additional post-marketing testing requirements; 

be required to perform additional clinical trials to support approval or be subject to additional post-marketing testing requirements; 

have regulatory authorities withdraw, or suspend, their approval of the product or impose restrictions on its distribution in the form of a risk 
evaluation and mitigation strategy, or REMS; 

be subject to the addition of labeling statements, such as warnings or contraindications; 

be sued; or 

experience damage to our reputation. 

Our product development costs will also increase if we experience delays in testing or obtaining marketing approvals. We do not know whether any 

of our preclinical studies or clinical trials will begin as planned, need to be restructured or be completed on schedule, if at all. 

Furthermore, our product candidates are based on certain innovative technology platforms, which makes it even more difficult to predict the time 

and cost of product candidate development and obtaining necessary regulatory approvals, particularly for our small interfering ribonucleic acid, or siRNA, 
and cytomegalovirus, or CMV, vector technologies. Relatively few siRNA product candidates have ever been tested in humans and to date few have 
received regulatory approval and market authorizations. In addition, the compounds we are developing may not demonstrate in patients the chemical and 
pharmacological properties ascribed to them in preclinical studies, and they may interact with human biological systems in unforeseen, ineffective or 
harmful ways. 

As part of our T cell platform, our approach is to use human CMV, or HCMV, as a vaccine vector to potentially treat and prevent pathogens 
refractory to current vaccine technologies because HCMV may induce potent and long-lasting T cell responses to a broader range of epitopes than observed 
for other viral vaccines. Safety and toxicity trials for this technology have so far only been conducted in animal species, in which HCMV has limited ability 
to replicate. If our first clinical trial for VIR-1111 causes unexpected side effects that are not tolerable in the treatment of the relevant patient group, the 
further development of the product candidates and any other potential products based on HCMV-vector technology may be significantly limited or become 
impossible. Also, because our HCMV-vector technology is novel, regulatory agencies may lack experience with product candidates such as VIR-1111, 
which may lengthen the regulatory review process, increase our development costs and delay or prevent commercialization of our product candidates. In 
addition, our HCMV-vector technology utilizes live-attenuated, genetically-modified organisms for which the FDA, the EMA, and other comparable 
foreign regulatory authorities and other public health authorities, such as the Centers for Disease Control and Prevention and hospitals involved in clinical 
trials, have established additional safety and contagion rules and procedures, which could establish additional hurdles for the development, manufacture or 
use of our vectors. These hurdles may lead to delays in the conduct of clinical trials or in obtaining regulatory approvals for further development, 
manufacturing or commercialization of our product candidates. 

Further, we, the FDA, a foreign regulatory authority or an institutional review board may place a full or partial hold on our clinical trials at any time 

if it appears that we or our collaborators are failing to conduct a trial in accordance with regulatory requirements, including the FDA’s current Good 
Clinical Practice, or GCP, regulations, that we are exposing participants to unacceptable health risks, or if the FDA or foreign regulatory authority finds 
deficiencies in our investigational new drug, or IND, applications or clinical trial applications, respectively, or the conduct of these trials. Moreover, we 
may not be able to file INDs to commence additional clinical trials on the timelines we expect because our filing schedule is dependent on further 
preclinical and manufacturing progress. Therefore, we cannot predict with any certainty the schedule for commencement and completion of future clinical 
trials. If we experience delays in the commencement or completion of our clinical trials, or if we terminate a clinical trial prior to completion, the 
commercial prospects of our product candidates could be negatively impacted, and our ability to generate revenue from our product candidates may be 
delayed. 

Enrollment and retention of patients in clinical trials is an expensive and time-consuming process and could be delayed, made more difficult or 
rendered impossible by multiple factors outside our control. 

87

 
 
Identifying and qualifying patients to participate in our clinical trials is critical to our success. We are developing sotrovimab and VIR-7832 for the 
treatment of COVID-19, VIR-2218 and VIR-3434 for the treatment of HBV, VIR-2482 for the prevention of influenza A, and VIR-1111 for the prevention 
of human immunodeficiency virus, or HIV. In particular, clinical trials for prophylaxis tend to require enrollment of a larger number of subjects than 
clinical trials for treatments. We may encounter difficulties in enrolling patients in our clinical trials, thereby delaying or preventing development and 
approval of our product candidates. Even once enrolled, we may be unable to retain a sufficient number of patients to complete any of our trials. Patient 
enrollment and retention in clinical trials depend on many factors, including the size of the patient population, the nature of the trial protocol, the existing 
body of safety and efficacy data, the number and nature of competing treatments and ongoing clinical trials of competing therapies for the same indication, 
the proximity of patients to clinical sites and the eligibility criteria for the trial. The enrollment and retention of patients in the clinical trials for sotrovimab 
and VIR-7832 for the treatment of COVID-19 may be disrupted or delayed as a result of clinicians’ and patients’ perceptions as to the potential advantages 
of sotrovimab and VIR-7832 in relation to other available therapies, including products that have been recently authorized under EUAs or approved and 
licensed through NDAs and BLAs to treat COVID-19 as well as any other new products that may be approved in the future for the treatment of COVID-19. 
While we have active clinical trial sites in the Ukraine and nearby European countries, if political or civil conditions require it, our sites may need to delay 
or suspend clinical trial activities. In addition, enrollment and retention of patients in clinical trials could be disrupted by geopolitical events, including civil 
or political unrest (such as the ongoing conflict between Ukraine and Russia), terrorism, insurrection or war, man-made or natural disasters, or public health 
pandemics or epidemics or other business interruptions, including, the current COVID-19 pandemic and future outbreaks of the disease. 

Our efforts to build relationships with patient communities may not succeed, which could result in delays in patient enrollment in our clinical trials. 

Any negative results we may report in clinical trials of our product candidates may make it difficult or impossible to recruit and retain patients in other 
clinical trials of that same product candidate. Delays or failures in planned patient enrollment or retention may result in increased costs, program delays or 
both, which could have a harmful effect on our ability to develop our product candidates or could render further development impossible. In addition, we 
may rely on contract research organizations, or CROs, and clinical trial sites to ensure proper and timely conduct of our future clinical trials and, while we 
intend to enter into agreements governing their services, we will be limited in our ability to ensure their actual performance. 

The continued spread of COVID-19 globally, or the evolution of new variants of COVID-19 that are more contagious, have more severe effects or 

are resistant to treatments or vaccinations, could adversely impact our preclinical or clinical trial operations in the United States, including our ability to 
enroll and retain patients as well as CROs and clinical trial site staff who, as healthcare providers, may have heightened exposure to COVID-19 if an 
outbreak occurs in their geography. In response to the COVID-19 pandemic, the FDA issued guidance on March 18, 2020, and subsequently updated it, to 
address the conduct of clinical trials during the pandemic. The guidance sets out a number of considerations for sponsors of clinical trials impacted by the 
pandemic, including the requirement to include in the clinical study report (or as a separate document) contingency measures implemented to manage the 
study, and any disruption of the study as a result of COVID-19; a list of all study participants affected by COVID-19-related study disruptions by a unique 
subject identifier and by investigational site, and a description of how the individual’s participation was altered; and analyses and corresponding 
discussions that address the impact of implemented contingency measures (e.g., participant discontinuation from investigational product and/or study, 
alternative procedures used to collect critical safety and/or efficacy data) on the safety and efficacy results reported for the study. There is no assurance that 
this guidance governing clinical studies during the pandemic will remain in effect or, even if it does, that it will help address the risks and challenges 
enumerated above. Accordingly, an inability to enroll a sufficient number of patients for the clinical trials would result in significant delays or might require 
us to abandon one or more clinical trials altogether.

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit their 
commercial potential or result in significant negative consequences following any potential marketing approval. 

During the conduct of clinical trials, patients report changes in their health, including illnesses, injuries and discomforts, to their doctor. Often, it is 

not possible to determine whether or not the product candidate being studied caused these conditions. Regulatory authorities may draw different 
conclusions and may require us to pause our clinical trials or require additional testing to confirm these determinations, if they occur. 

In addition, it is possible that as we test our product candidates in larger, longer and more extensive clinical trials, or as use of these product 
candidates becomes more widespread if they receive regulatory approval, illnesses, injuries, discomforts and other adverse events that were not observed in 
earlier trials, as well as conditions that did not occur or went undetected in 

88

 
 
previous trials, will be reported by subjects or patients. Many times, side effects are only detectable after investigational products are tested in large-scale 
pivotal trials or, in some cases, after they are made available to patients on a commercial scale after approval. If additional clinical experience indicates that 
any of our product candidates have side effects or cause serious or life-threatening side effects, the development of the product candidate may fail or be 
delayed, or, if the product candidate has received regulatory approval, such approval may be revoked, which would harm our business, financial condition, 
results of operations and prospects.  

We are a party to strategic collaboration and license agreements pursuant to which we are obligated to make substantial payments upon achievement of 
milestone events and, in certain cases, have relinquished important rights over the development and commercialization of certain current and future 
product candidates. We also intend to explore additional strategic collaborations, which may never materialize or may require that we relinquish rights 
to and control over the development and commercialization of our product candidates. 

We are a party to various strategic collaboration and license agreements that are important to our business and to our current and future product 

candidates pursuant to which we license a number of technologies to form our technology platforms. These agreements contain obligations that require us 
to make substantial payments in the event certain milestone events are achieved. We may in the future be required to make these payments, which could 
adversely affect our financial condition. In addition, we cannot be certain that we will achieve the results or benefits that justify entering into these 
agreements. For additional information regarding these and other collaboration, license and grant agreements, see the section titled “Business—Our 
Collaboration, License and Grant Agreements.”

A core element of our business strategy also includes continuing to acquire or in-license additional technologies or product candidates for the 
treatment and prevention of serious infectious diseases. As a result, we intend to periodically explore a variety of possible strategic collaborations or 
licenses in an effort to gain access to additional product candidates, technologies or resources. 

At this time, we cannot predict what form such strategic collaborations or licenses might take in the future. We are likely to face significant 
competition in seeking appropriate strategic collaborators, and strategic collaborations and licenses can be complicated and time-consuming to negotiate 
and document. We may not be able to negotiate strategic collaborations on acceptable terms, or at all. We are unable to predict when, if ever, we will enter 
into any additional strategic collaborations or licenses because of the numerous risks and uncertainties associated with establishing them. Any delays in 
entering into new strategic collaborations or licenses related to our product candidates could delay the development and commercialization of our product 
candidates in certain geographies for certain indications, which would harm our business prospects, financial condition and results of operations. 

Our current and future strategic collaborations and licenses could subject us to a number of risks, including the following: 

•

•

•

•

•

•

•

•

we may be required to undertake the expenditure of substantial operational, financial and management resources; 

we may be required to assume substantial actual or contingent liabilities; 

we may not be able to control the amount and timing of resources that our strategic collaborators devote to the development or 
commercialization of our product candidates; 

strategic collaborators may select indications or design clinical trials in a way that may be less successful than if we were doing so; 

strategic collaborators may delay clinical trials, provide insufficient funding, terminate a clinical trial or abandon a product candidate, repeat 
or conduct new clinical trials or require a new version of a product candidate for clinical testing; 

strategic collaborators may not pursue further development and commercialization of products resulting from the strategic collaboration 
arrangement or may elect to discontinue research and development programs; 

disputes may arise between us and our strategic collaborators that result in costly litigation or arbitration that diverts management’s attention 
and consumes resources; 

strategic collaborators may experience financial difficulties; 

89

 
 
•

•

strategic collaborators may not properly maintain, enforce or defend our intellectual property rights or may use our proprietary information in 
a manner that could jeopardize or invalidate our proprietary information or expose us to potential litigation; and

strategic collaborators could terminate the arrangement or allow it to expire, which would delay the development and may increase the cost 
of developing our product candidates. 

Furthermore, license agreements we enter into in the future may not provide exclusive rights to use intellectual property and technology in all 
relevant fields of use and in all territories in which we may wish to develop or commercialize our technology and products. As a result, we may not be able 
to prevent competitors from developing and commercializing competitive products in territories included in all of our licenses. 

If the market opportunities for our product candidates are smaller than we believe they are or any approval we obtain is based on a narrower definition 
of the patient population, our business may suffer. 

We currently focus our product development on product candidates for the treatment and prevention of serious infectious diseases. Our eligible 
patient population, pricing estimates and available coverage and reimbursement may differ significantly from the actual market addressable by our product 
candidates. Our estimates of the number of people who have these diseases, the subset of people with these diseases who have the potential to benefit from 
treatment with our product candidates, and the market demand for our product candidates are based on our beliefs and analyses. These estimates have been 
derived from a variety of sources, including the scientific literature, patient foundations or market research, and may prove to be incorrect. Further, new 
trials may change the estimated incidence or prevalence of the diseases we are targeting. The number of patients may turn out to be lower than expected. 
Likewise, the potentially addressable patient population for each of our product candidates may be limited or may not be receptive to treatment with our 
product candidates, and new patients may become increasingly difficult to identify or access. Additionally, the availability of superior or competitive 
therapies from our competitors could negatively impact or eliminate market demand for our product candidates. If the market opportunities for our product 
candidates are smaller than we estimate, it could have an adverse effect on our business, financial condition, results of operations and prospects. 

We face substantial competition, which may result in others developing or commercializing products before or more successfully than us. 

The biopharmaceutical industry is characterized by rapidly advancing technologies, intense competition and an emphasis on proprietary products. 
We face potential competition from many different sources, including pharmaceutical and biotechnology companies, academic institutions, governmental 
agencies and public and private research institutions.  

Our commercialization potential could be reduced or eliminated if our competitors develop and commercialize products that are safer, more 
effective, have fewer or less severe side effects, are more convenient or are less expensive than products that we may develop. The key competitive factors 
affecting the success of all our programs are likely to be efficacy, safety, convenience and timing. Our competitors also may obtain FDA or other regulatory 
approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position 
before we are able to enter the market. 

In addition, regulatory incentives to develop products for treatment of infectious diseases have increased interest and activity in this area and may 

lead to increased competition for clinical investigators and clinical trial subjects, as well as for future prescriptions, if any of our product candidates are 
successfully developed and approved. 

Our competitors may have significantly greater financial resources, established presence in the market, expertise in research and development, 
manufacturing, preclinical and clinical testing, obtaining regulatory approvals and reimbursement and marketing approved products than we do. These 
competitors also compete with us in acquiring third-party contract manufacturing capacity and raw materials, recruiting and retaining qualified scientific, 
sales, marketing and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies 
complementary to, or necessary for, our programs. Smaller or early-stage companies may also prove to be significant competitors, particularly through 
collaborative arrangements with large and established companies. Additional mergers and acquisitions may result in even more resources being 
concentrated in our competitors.

Since the beginning of the COVID-19 pandemic, and even before, there has been substantial research in the development of new drugs and biologics 

to address diseases caused by the coronavirus. Numerous large and small 

90

 
 
  
pharmaceutical and biotechnology companies are developing COVID-19 therapy programs with various mechanisms of actions, including prophylactic 
vaccines, oral antivirals, immunomodulators, and antibodies, some of which are further along in the development process than we are. Other parties may be 
successful in producing a more efficacious therapy for SARS-CoV-2 or in producing a therapy that is easier to deliver and administer to patients in a 
timelier manner, which may also lead to the diversion of funding away from us and toward other companies or lead to decreased demand for our potential 
therapies. Companies with antibodies in clinical development include AbbVie, Inc., Adagio Therapeutics, or Adagio, AstraZeneca plc, or AstraZeneca, Brii 
Bio, Celltrion Healthcare Co., Ltd., Eli Lilly and Company, or Eli Lilly, and Regeneron Pharmaceuticals, Inc. Companies with oral antivirals in clinical 
development include Shionogi Inc., Gilead Sciences, Inc., or Gilead, and others. Companies with prophylactic vaccines in clinical development include 
AstraZeneca, GSK, Novavax, Inc. and Sanofi S.A. The industry and competitive landscape for COVID-19 treatments is rapidly changing, and we could 
have more competition in the future.

The availability of superior or competitive therapies, or preventative measures such as vaccines, coupled with the unpredictable nature of pandemics 

and the prevalence of new variants of COVID-19, could negatively impact or eliminate demand for our COVID-19 therapies. Product candidates that we 
successfully develop and commercialize may compete with existing therapies, including prophylactic vaccines, competing antibody therapies, oral 
antivirals, and new therapies that may become available in the future. In addition, one or more of our competitors may be successful in producing a more 
efficacious therapy for SARS-CoV-2 and current and future variants or in producing a therapy that is easier to deliver and administer to patients in a 
timelier manner. For example, there are FDA-approved treatments for COVID-19 including an intravenously administered antiviral, remdesivir, marketed 
by Gilead, which is FDA approved for the treatment of COVID-19 in both outpatient and hospitalized settings, and several treatments and a prophylactic 
vaccine are available under EUA. Additionally, Pfizer’s COVID-19 vaccine, Comirnaty®, is approved by the FDA for individuals 16 years of age or older, 
Moderna, Inc.’s COVID-19 vaccine, Spikevax®, is approved by the FDA for individuals 18 years of age or older and a COVID-19 vaccine is available in 
the United States under EUA from Janssen Biotech, Inc. In December 2021 the FDA approved EUAs for the oral antiviral, molnupiravir, from Merck & 
Co., Inc., or Merck, for the treatment of mild-to-moderate COVID-19 in adults with positive results of direct SARS-CoV-2 viral testing, and who are at 
high risk for progression to severe COVID-19, including hospitalization or death, and for whom alternative COVID-19 treatment options authorized by the 
FDA are not accessible or clinically appropriate, which has shown topline efficacy of 30% reduction in risk for hospitalization or death risk in early 
treatment clinical trials, and the oral antiviral, paxlovid, from Pfizer for the treatment of mild-to-moderate COVID-19 in adults and pediatric patients (12 
years of age and older weighing at least 40 kilograms) with positive results of direct SARS-CoV-2 testing, and who are at high risk for progression to 
severe COVID-19, including hospitalization or death, which has demonstrated an 89% reduction in risk of COVID-19-related hospitalization or death. In 
February 2022, the FDA approved an EUA for Eli Lilly's antibody, bebtelovimab, for the treatment of mild to moderate COVID-19 in adults and pediatric 
patients (12 years of age and older weighing at least 40 kilograms) with positive results of direct SARS-CoV-2 testing, and who are at high risk for 
progression to severe COVID-19, including hospitalization or death. Merck, Pfizer and Eli Lilly have all been successful in securing government support 
and funding. AstraZeneca’s AZD7442, a cocktail of two monoclonal antibodies, showed topline efficacy of 50% reduction in risk for hospitalization or 
death risk in early treatment clinical trials. Other companies like AstraZeneca and Adagio have been successful in securing government support and 
funding, respectively, and are in the process of developing antibody therapies that, if successful, could be effective against known viral variants and be 
administered via intramuscular, or IM, injection. 

As a result of these factors, our competitors may achieve patent protection or obtain regulatory approval of their products before we are able to, 

which may limit our ability to develop or commercialize our product candidates. Our competitors may also develop therapies that are safer, more effective, 
more widely accepted or less expensive than ours, and may also be more successful than we are in manufacturing and marketing their products. These 
advantages could render our product candidates obsolete or non-competitive before we can recover the costs of such product candidates’ development and 
commercialization. For additional information regarding our competitors, see the section titled “Business—Competition.” 

Even if any product candidates receive marketing approval, they may fail to achieve market acceptance by physicians, patients, third-party payors or 
others in the medical community necessary for commercial success. 

To date, sotrovimab has been granted EUA, temporary authorization or marketing approval (under the brand name Xevudy®) in more than 40 

countries. Even if any product candidates receive marketing approval, they may fail to gain market acceptance by physicians, patients, third-party payors 
and others in the medical community. If such product candidates do not achieve an adequate level of acceptance, we may not generate significant product 
revenue and may not become profitable. The degree of market acceptance of any product candidate, if approved for commercial sale, will depend on a 
number of factors, including but not limited to: 

•

the convenience and ease of administration compared to alternative treatments and therapies; 

91

 
 
•

•

•

•

•

•

•

•

•

•

the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies; 

the efficacy and potential advantages compared to alternative treatments and therapies; 

the effectiveness of sales and marketing efforts;  

the strength of our relationships with patient communities; 

the cost of treatment in relation to alternative treatments and therapies, including any similar generic treatments; 

our ability to offer such product for sale at competitive prices; 

the strength of marketing and distribution support; 

the availability of third-party coverage and adequate reimbursement, and patients’ willingness to pay out-of-pocket in the absence of third-
party coverage or adequate reimbursement;

the prevalence and severity of any side effects; and 

any restrictions on the use of the product together with other medications. 

If any of our product candidates are approved but fail to achieve market acceptance among physicians, patients, third-party payors and others in the 

medical community, we will not be able to generate significant revenue, which would compromise our ability to become profitable. 

Even if we obtain regulatory approvals for our product candidates, they will remain subject to ongoing regulatory oversight. 

Even if we obtain regulatory approval in a jurisdiction, the regulatory authority may still impose significant restrictions on the indicated uses or 
marketing of our product candidates, or impose ongoing requirements for potentially costly post-approval trials, post-market surveillance or patient or drug 
restrictions. Additionally, the holder of an approved BLA is required to comply with FDA rules and is subject to FDA review and periodic inspections, in 
addition to other potentially applicable federal and state laws, to ensure compliance with current good manufacturing practices, or cGMP, and adherence to 
commitments made in the BLA.

If we or a regulatory agency discovers previously unknown problems with a product such as adverse events of unanticipated severity or frequency, 
or problems with the facility where the product is manufactured, a regulatory agency may impose restrictions relative to that product or the manufacturing 
facility, including requiring recall or withdrawal of the product from the market or suspension of manufacturing. Moreover, product labeling, advertising 
and promotion for any approved product will be subject to regulatory requirements and continuing regulatory review. For example, a company may not 
promote “off-label” uses for its drug products. An off-label use is the use of a product for an indication that is not described in the product’s FDA-approved 
or authorized label in the United States or for uses in other jurisdictions that differ from those approved by the applicable regulatory agencies. Physicians, 
on the other hand, may prescribe products for off-label uses. Although the FDA and comparable foreign regulatory agencies do not regulate a physician’s 
choice of drug treatment made in the physician’s independent medical judgment, they do restrict promotional communications from companies or their 
sales force with respect to off-label uses of products for which marketing clearance has not been issued. 

Failure to comply with such requirements, when and if applicable, could subject us to a number of actions ranging from warning letters to product 

seizures or significant fines, among other actions. The FDA and other agencies, including the Department of Justice, or the DOJ, closely regulate and 
monitor the post-approval marketing and promotion of products to ensure that they are marketed and distributed only for the approved indications and in 
accordance with the provisions of the approved labeling. The FDA and DOJ impose stringent restrictions on manufacturers’ communications regarding off-
label use and if we market our medicines for uses other than their respective approved indications, we may be subject to enforcement action for off-label 
marketing. Violations of the Food, Drug, and Cosmetic Act and other statutes, including the False Claims Act, relating to the promotion and advertising of 
prescription drugs may lead to investigations and enforcement actions alleging violations of federal and state health care fraud and abuse laws, as well as 
state consumer protection laws, which violations may result in the imposition of significant administrative, civil and criminal penalties. Any government 
investigation of alleged violations of laws or regulations could require us to expend significant time and resources in response and could generate negative 
publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue. 
For additional information regarding regulatory approval and ongoing regulatory oversight, see the section titled “Business—Government Regulation and 
Product Approval.”

92

 
 
If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our product candidates, we 
may not be successful in commercializing them, if and when they are approved. 

To successfully commercialize any product candidate that may result from our development programs, we will need to build out our sales and 

marketing capabilities, either on our own or with others. The establishment and development of our own commercial team or the establishment of a 
contract sales force to market any product candidate we may develop will be expensive and time-consuming and could delay any product launch. 
Moreover, we cannot be certain that we will be able to successfully develop this capability, and have no experience as a company in commercializing 
products. Establishing sales and marketing capabilities will be particularly important to the commercial success of our product candidates that target 
diseases with large patient populations throughout the world. We may seek to enter into collaboration agreements with other entities to utilize their 
established marketing and distribution capabilities, but we may be unable to enter into such agreements on favorable terms, if at all. For example, GSK is 
primarily responsible for the commercialization of sotrovimab. If any current or future collaborators, including GSK, do not commit sufficient time or 
resources to commercialize our product candidates, or we are unable to develop the necessary capabilities on our own, we may be unable to generate 
sufficient revenue to sustain our business. We compete with many companies that currently have extensive, experienced and well-funded marketing and 
sales operations to recruit, hire, train and retain marketing and sales personnel, and will have to compete with those companies to recruit, hire, train and 
retain any of our own marketing and sales personnel. We will likely also face competition if we seek third parties to assist us with the sales and marketing 
efforts of our product candidates. Without an internal team or the support of a third party to perform marketing and sales functions, we may be unable to 
compete successfully against these more established companies. 

Even if we obtain and maintain approval for our product candidates from the FDA, we may never obtain approval outside the United States, which 
would limit our market opportunities. 

Approval of a product candidate in the United States by the FDA does not ensure approval of such product candidate by regulatory authorities in 

other countries or jurisdictions, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other foreign 
countries or by the FDA. Sales of our product candidates outside the United States will be subject to foreign regulatory requirements governing clinical 
trials and marketing approval. Even if the FDA grants marketing approval for a product candidate, comparable foreign regulatory authorities also must 
approve the manufacturing and marketing of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve 
requirements and administrative review periods different from, and more onerous than, those in the United States, including additional preclinical studies or 
clinical trials. In many countries outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in 
that country. In some cases, the price that we intend to charge for any product candidates, if approved, is also subject to approval. Obtaining approval for 
our product candidates in the EU from the European Commission following the opinion of the EMA if we choose to submit a marketing authorization 
application there, would be a lengthy and expensive process. Even if a product candidate is approved, the EMA may limit the indications for which the 
product may be marketed, require extensive warnings on the product labeling or require expensive and time-consuming additional clinical trials or 
reporting as conditions of approval. Approval of certain product candidates outside of the United States, particularly those that target diseases that are more 
prevalent outside of the United States will be particularly important to the commercial success of such product candidates. Obtaining foreign regulatory 
approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the 
introduction of our product candidates in certain countries. 

In addition, on June 23, 2016, the electorate in the U.K. voted in favor of leaving the EU, commonly referred to as Brexit. Following protracted 
negotiations, the U.K. left the EU on January 31, 2020, and a transition period to December 31, 2020, was established to allow the U.K. and the EU to 
negotiate the U.K.’s withdrawal. As a result, effective January 1, 2021, the U.K. is no longer part of the European Single Market and European Union 
Customs Union. A co-operation agreement was signed between the U.K. and the EU in December 2020 which has been applied provisionally since January 
1, 2021, until it is ratified by all parties to that agreement. The agreement addresses trade, economic arrangements, law enforcement, judicial cooperation 
and a governance framework including procedures for dispute resolution, among other things. As both parties continue to work on the rules for 
implementation, significant political and economic uncertainty remains about how the precise terms of the relationship between the parties will differ from 
the terms before withdrawal. 

Since the regulatory framework for pharmaceutical products in the U.K. covering the quality, safety, and efficacy of pharmaceutical products, 

clinical trials, marketing authorization, commercial sales, and distribution of pharmaceutical products is derived from EU directives and regulations, the 
consequences of Brexit and the impact the future regulatory regime that applies to products and the approval of product candidates in the U.K. remains 
unclear. As of January 1, 2021, the Medicines and Healthcare products Regulatory Agency, or the MHRA, became responsible for supervising medicines 
and 

93

 
 
 
medical devices in Great Britain, comprising England, Scotland and Wales under domestic law, whereas Northern Ireland will continue to be subject to EU 
rules under the Northern Ireland Protocol. The MHRA will rely on the Human Medicines Regulations 2012 (SI 2012/1916) (as amended), or the HMR, as 
the basis for regulating medicines. The HMR has incorporated into the domestic law of the body of EU law instruments governing medicinal products that 
pre-existed prior to the U.K.’s withdrawal from the EU. Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or 
otherwise, may force us to restrict or delay efforts to seek regulatory approval in the U.K. for our product candidates, which could significantly and 
materially harm our business.

Further, clinical trials conducted in one country may not be accepted by regulatory authorities in other countries. Also, regulatory approval for our 

product candidates may be withdrawn. If we fail to comply with the applicable regulatory requirements, our target market will be reduced and our ability to 
realize the full market potential of our product candidates will be harmed and our business, financial condition, results of operations and prospects could be 
harmed. 

If we commercialize our product candidates outside the United States, a variety of risks associated with international operations could harm our 
business. 

We intend to seek approval to market our product candidates outside the United States, and may also do so for future product candidates. If we 

market approved products outside the United States, we expect that we will be subject to additional risks in commercialization.

We have no prior experience in these areas. In addition, there are complex regulatory, tax, labor and other legal requirements imposed by many of 

the individual countries in which we may operate, with which we will need to comply. Many biopharmaceutical companies have found the process of 
marketing their products in foreign countries to be challenging. 

Negative developments and negative public opinion of new technologies on which we rely may damage public perception of our product candidates or 
adversely affect our ability to conduct our business or obtain regulatory approvals for our product candidates. 

The clinical and commercial success of our product candidates will depend in part on public acceptance of the use of new technologies for the 

prevention or treatment of human diseases. For example, we use CMV, a commonly occurring virus in humans, as a vaccine vector to prevent and treat 
pathogens refractory to current vaccine technologies. We also use CRISPR gene-editing technology as a research tool to systematically identify human 
genes that control infection. 

Public perception may be influenced by claims that CMV technology is unsafe and products incorporating this technology may not gain the 
acceptance of the public or the medical community, or that CRISPR gene-editing technology is unethical or immoral. Adverse public attitudes may 
adversely impact our ability to enroll clinical trials. Moreover, our success will depend upon physicians specializing in our targeted diseases prescribing, 
and their patients being willing to receive, our product candidates as treatments in lieu of, or in addition to, existing, more familiar, treatments for which 
greater clinical data may be available. Any increase in negative perceptions of the technologies that we rely on may result in fewer physicians prescribing 
our products or may reduce the willingness of patients to utilize our products or participate in clinical trials for our product candidates. 

Increased negative public opinion or more restrictive government regulations in response thereto, would have a negative effect on our business, 

financial condition, results of operations or prospects and may delay or impair the development and commercialization of our product candidates or 
demand for such product candidates. Adverse events in our preclinical studies or clinical trials or those of our competitors or of academic researchers 
utilizing similar technologies, even if not ultimately attributable to product candidates we may discover and develop, and the resulting publicity could result 
in increased governmental regulation, unfavorable public perception, potential regulatory delays in the testing or approval of potential product candidates 
we may identify and develop, stricter labeling requirements for those product candidates that are approved, a decrease in demand for any such product 
candidates and a suspension or withdrawal of approval by regulatory authorities of our product candidates. 

Product liability lawsuits against us could cause us to incur substantial liabilities and could limit commercialization of any product candidate that we 
may develop. 

We face an inherent risk of product liability exposure related to the testing of our product candidates in clinical trials and may face an even greater 

risk if we commercialize any product candidate that we may develop. If we cannot successfully 

94

 
 
 
 
defend ourselves against claims that any such product candidates caused injuries, we could incur substantial liabilities. Regardless of merit or eventual 
outcome, liability claims may result in: 

•

•

•

•

•

•

•

•

decreased demand for any product candidate that we may develop;

loss of revenue;

substantial monetary awards to trial participants or patients;

significant time and costs to defend the related litigation;

withdrawal of clinical trial participants;

increased insurance costs;

the inability to commercialize any product candidate that we may develop; and

injury to our reputation and significant negative media attention.

Any such outcomes could negatively impact our business, financial condition, results of operations and prospects. 

Our insurance policies may be inadequate and potentially expose us to unrecoverable risks. 

Although we maintain product liability insurance coverage, such insurance may not be adequate to cover all liabilities that we may incur. We 
anticipate that we will need to increase our insurance coverage each time we commence a clinical trial and if we successfully commercialize any product 
candidate. Insurance availability, coverage terms and pricing continue to vary with market conditions. We endeavor to obtain appropriate insurance 
coverage for insurable risks that we identify such as cybersecurity-related issues; however, we may fail to correctly anticipate or quantify insurable risks, 
we may not be able to obtain appropriate insurance coverage and insurers may not respond as we intend to cover insurable events that may occur. 
Conditions in the insurance markets relating to nearly all areas of traditional corporate insurance change rapidly and may result in higher premium costs, 
higher policy deductibles and lower coverage limits. For some risks, we may not have or maintain insurance coverage because of cost or availability. 

Risks Related to Regulatory Compliance 

The regulatory pathways for our product candidates targeting SARS-CoV-2, the virus that causes COVID-19, are continually evolving, and may result 
in unexpected or unforeseen challenges.

Our product candidates targeting SARS-CoV-2, the virus that causes COVID-19, are in various development and approval stages. To date, 

sotrovimab has been granted EUA, temporary authorization or marketing approval (under the brand name Xevudy®) in more than 40 countries. 
Sotrovimab completed a Phase 2 clinical trial evaluating an IM formulation. In the second quarter of 2021, we initiated and completed an additional Phase 
3 clinical trial evaluating an IM formulation of sotrovimab and a Phase 1b/2a clinical trial for VIR-7832, also a SARS-CoV-2-neutralizing mAb. The speed 
at which companies and institutions are acting to create and test many therapeutics and vaccines for COVID-19 is unusual, and evolving or changing plans 
or priorities within the FDA, including changes based on new knowledge of COVID-19, variants of the disease and how the disease affects the human 
body, which may significantly affect the regulatory timelines for our COVID-19 product candidates. Results from our continued development and planned 
clinical trials may raise new questions and require us to redesign proposed clinical trials, including revising proposed endpoints or adding new clinical trial 
sites or cohorts of subjects. As part of these ongoing discussions, the FDA may require us to conduct additional preclinical studies and/or clinical trials than 
we originally anticipated, which could result in significant delay in our development program for these product candidates. For example, the FDA has 
asked for additional data to support our conclusion that the 500 mg IV dose of sotrovimab retains activity against the BA.2 Omicron subvariant based on 
our current modeling assumptions as well as safety data for higher doses. We could be required to perform additional studies and trials on sotrovimab based 
on any additional feedback we may receive from the FDA.

The FDA has the authority to grant an EUA to allow unapproved medical products to be used in an emergency to diagnose, treat, or prevent serious 

or life-threatening diseases or conditions when, based on the totality of scientific evidence, there is evidence of effectiveness of the medical product, and 
there are no adequate, approved, and available alternatives. Our EUA for sotrovimab, for example, authorizes us to distribute sotrovimab prior to full FDA 
approval. However, the FDA may revoke an EUA where it is determined that the underlying public health emergency no longer exists or warrants such 
authorization, and we cannot predict how long, if ever, an EUA would remain in place. Such revocation could adversely impact our business in a variety of 
ways, including if one of our COVID-19 product candidates, such as sotrovimab, is not 

95

 
 
 
 
yet approved by the FDA and if we and our commercialization and manufacturing partners have invested in the commercialization and manufacturing of 
such product candidate under an EUA.

If any of our future small molecule drug product candidates obtain regulatory approval, competitors could enter the market with generic or follow-on 
versions of such products, which may result in a material decline in sales of affected products. 

Under the Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Act, a pharmaceutical manufacturer may file an 

abbreviated new drug application, or ANDA, seeking approval of a generic version of an approved, small molecule innovator drug product. Under the 
Hatch-Waxman Act, a manufacturer may also submit an NDA under section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act that references the 
FDA’s prior approval of the small molecule innovator product. A 505(b)(2) NDA product may be for a new or improved version of the original innovator 
product. The Hatch-Waxman Act also provides for certain periods of regulatory exclusivity, which preclude FDA approval (or in some circumstances, FDA 
filing and review) of an ANDA or 505(b)(2) NDA. In addition to the benefits of regulatory exclusivity, an innovator NDA holder may have patents 
claiming the active ingredient, product formulation or an approved use of the drug, which would be listed with the product in the FDA publication, 
“Approved Drug Products with Therapeutic Equivalence Evaluations,” known as the Orange Book, see the section titled “—Risks Related to Our 
Intellectual Property— Patent terms may be inadequate to protect our competitive position on our product candidates or any products approved in the future 
for an adequate amount of time and additional competitors could enter the market with generic or biosimilar versions of such products.”

Accordingly, if any of our future small molecule drug product candidates are approved, competitors could file ANDAs following the expiration of 

regulatory exclusivity for generic versions of these products or 505(b)(2) NDAs that reference our products. If competitors are able to obtain marketing 
approval for generics referencing our small molecule drug product candidates, such competitive products may be able to immediately compete with us in 
each indication for which our product candidates may have received approval. They may also be prescribed by healthcare providers for off-label uses that 
are otherwise protected by regulatory exclusivity. For additional information regarding competition, see the section titled “Business—Competition.”

Any biologic, or large molecule, product candidates for which we intend to seek approval may face competition sooner than anticipated. 

If we are successful in achieving regulatory approval to commercialize any biologic product candidate faster than our competitors, such product 

candidates may face competition from biosimilar products. In the United States, large molecule product candidates generally are regulated by the FDA as 
biologic products subject to approval and licensure under the BLA pathway. The Biologics Price Competition and Innovation Act of 2009, or BPCIA, 
creates an abbreviated pathway for the approval of biosimilar and interchangeable biologic products following the approval of an original BLA. For 
additional information regarding biosimilars and exclusivity, see the section titled “Business—Government Regulation and Product Approval—Biosimilars 
and Regulatory Exclusivity.”

If competitors are able to obtain marketing approval for biosimilars referencing our large molecule product candidates, if approved and after the 

expiration of regulatory exclusivity, such products may become subject to competition from such biosimilars, with the attendant competitive pressure and 
potential adverse consequences. Such competitive products may be able to immediately compete with us in each indication for which our product 
candidates may have received approval. In addition, the extent to which any regulatory exclusivity may apply to products authorized under an EUA is 
unclear. For additional information regarding competition, see the section titled “Business—Competition”.

In addition, we may also face competition from product candidates that receive EUA approval, which could negatively impact sales of our EUA 
product and other product candidates. For example, numerous large and small pharmaceutical and biotechnology companies are developing COVID-19 
therapy programs, including prophylactic vaccines, oral antivirals, immunomodulators, and antibodies, some of which have received full approval or EUAs 
from the FDA. For additional information regarding competition, see the section titled “—Risks Related to the Development and Commercialization — We 
face substantial competition, which may result in others developing or commercializing products before or more successfully than us.”

Our relationships with customers, physicians, and third-party payors are subject, directly or indirectly, to federal and state healthcare fraud and abuse 
laws, false claims laws, and other healthcare laws and regulations. If we are unable to comply, or have not fully complied, with such laws, we could 
face substantial penalties. 

Healthcare providers, physicians and third-party payors in the United States and elsewhere play a primary role in the recommendation and 

prescription of our EUA product and will play a primary role in the recommendation and prescription of any product candidates for which we obtain 
marketing approval. Our current and future arrangements with healthcare professionals, principal investigators, consultants, customers and third-party 
payors subject us to various federal and state fraud and abuse laws and other healthcare laws, such as the U.S. federal Anti-Kickback Statute, federal civil 
and criminal false claims laws, the healthcare fraud provisions of the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, and 
the Physician Payments Sunshine Act. 

These laws may constrain the business or financial arrangements and relationships through which we conduct our operations, including how we 

research, market, sell and distribute our EUA product and additional product candidates, if approved. For additional information regarding these laws, see 
the section titled “Business—Government Regulation and Product Approval”. Ensuring that our internal operations and business arrangements with third 
parties comply with applicable healthcare laws and regulations will likely be costly. It is possible that governmental authorities will conclude that our 
business practices, including our relationships with physicians and other healthcare providers, some of whom are compensated in the form of stock options 
for consulting services provided, may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other 
healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to 
us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participating 
in government-funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a 
corporate integrity agreement or similar agreement to resolve allegations of noncompliance with these laws, contractual damages, reputational harm and the 
curtailment or restructuring of our operations.  

If the physicians or other providers or entities with whom we expect to do business are found not to be in compliance with applicable laws, they may 
be subject to significant civil, criminal or administrative sanctions, including exclusions from government-funded healthcare programs. Even if resolved in 
our favor, litigation or other legal proceedings relating to healthcare laws and regulations may cause us to incur significant expenses and could distract our 
technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, 
motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial 
adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources 
available for development, manufacturing, sales, marketing or distribution activities. Uncertainties resulting from the initiation and continuation of 
litigation or other proceedings relating to applicable healthcare laws and regulations could have an adverse effect on our ability to compete in the 
marketplace. 

Coverage and adequate reimbursement may not be available for our EUA product and any product candidates that we commercialize, if approved, 
which could make it difficult for us to sell profitably. 

Market acceptance and sales of our EUA product and any product candidates that we commercialize, if approved, may depend in part on the extent 

to which reimbursement for these product and related treatments will be available from third-party payors, including government health administration 
authorities, managed care organizations and other private health insurers. Third-party payors decide which therapies they will pay for and establish 
reimbursement levels. While no uniform policy for coverage and reimbursement exists in the United States, third-party payors often rely upon Medicare 
coverage policy and payment limitations in setting their own coverage and reimbursement policies. However, decisions regarding the extent of coverage 
and amount of reimbursement to be provided for our EUA product and any product candidates that we develop will be made on a payor-by-payor basis. 
Therefore, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage, and adequate 
reimbursement, for the product. Additionally, a third-party payor’s decision to provide coverage for a therapy does not imply that an adequate 
reimbursement rate will be approved. Each payor determines whether or not it will provide coverage for a therapy, what amount it will pay the 
manufacturer for the therapy and on what tier of its formulary it will be placed. The position on a payor’s list of covered drugs and biological products, or 
formulary, generally determines the co-payment that a patient will need to make to obtain the therapy and can strongly influence the adoption of such 
therapy by patients and physicians. Patients who are prescribed treatments for their conditions and providers prescribing such services generally rely on 
third-party payors to reimburse all or part of the associated healthcare costs. Patients are unlikely to use our products unless coverage is provided and 
reimbursement is adequate to cover a significant portion of the cost of our products. In addition, because our EUA product and certain of our product 
candidates are physician-administered, separate reimbursement for the product itself may or may 

97

 
 
not be available. Instead, the administering physician may only be reimbursed for providing the treatment or procedure in which our product is used. 

Third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. We cannot be 

sure that coverage and reimbursement will be available for our EUA product or any product that we commercialize and, if reimbursement is available, what 
the level of reimbursement will be. Inadequate coverage and reimbursement may impact the demand for, or the price of, our EUA product or any product 
for which we obtain marketing approval. If coverage and adequate reimbursement are not available, or are available only at limited levels, we may not be 
able to successfully commercialize our EUA product or any product candidates that we develop. 

Healthcare legislative reform measures may have a negative impact on our business, financial condition, results of operations and prospects. 

In the United States and some foreign jurisdictions, there have been, and we expect there will continue to be, several legislative and regulatory 

changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate 
post-approval activities and affect our ability to profitably sell our EUA product or any product candidates for which we obtain marketing approval. In 
particular, there have been and continue to be a number of initiatives at the U.S. federal and state levels that seek to reduce healthcare costs and improve the 
quality of healthcare 

We expect that additional U.S. federal healthcare reform measures will be adopted in the future, particularly in light of the new Presidential 
administration, any of which could limit the amounts that the U.S. federal government will pay for healthcare products and services, which could result in 
reduced demand for our current or any future product candidates or additional pricing pressures. It is possible that additional governmental action is taken 
in response to the COVID-19 pandemic. For example, on June 17, 2021, the U.S. Supreme Court dismissed a challenge on procedural grounds that argued 
the Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively the ACA, is unconstitutional in its entirety 
because the “individual mandate” was repealed by Congress. Thus, the ACA will remain in effect in its current form. Additionally, in August 2011, the 
President signed into law the Budget Control Act of 2011, as amended, which, among other things, included aggregate reductions to Medicare payments to 
providers of 2% per fiscal year, which began in 2013 and, following passage of subsequent legislation, including the Bipartisan Budget Act of 2018, will 
continue through 2031. However, pursuant to the Coronavirus Aid, Relief and Economic Security Act, or the CARES Act, and subsequent legislation, these 
Medicare sequester reductions have been suspended through the end of March 2022. From April 2022 through June 2022 a 1% sequester cut will be in 
effect, with the full 2% cut resuming thereafter. Further, in February 2021 the FDA issued guidance strongly recommending that individual monoclonal 
antibody products be developed with the expectation that they will be combined with one or more monoclonal antibody products that bind to different 
epitopes to minimize the risk of losing activity against emergent variants. This type of government action could have a negative impact on our business, 
financial condition, results of operations and prospects. 

Additionally, as a result of litigation challenging the interim final rule implementing President Trump’s Most Favored Nation executive order, which 
would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically advanced countries, on August 
10, 2021, the Centers for Medicare & Medicaid Services, or CMS, published a proposed rule that seeks to rescind the Most Favored Nation Model interim 
final rule. In July 2021 the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions 
aimed at prescription drugs. In response to President Biden’s executive order, on September 9, 2021, the U.S. Department of HHS released a 
Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies 
that Congress could pursue to advance these principles. In addition, Congress is considering drug pricing as part of the budget reconciliation process. 
Further, it is possible that additional governmental action will be taken in response to the COVID-19 pandemic. We cannot predict the likelihood, nature or 
extent of government regulation that may arise from future legislation or administrative action in the United States or any other jurisdiction. If we or any 
third parties we may engage are slow or unable to adapt to changes in existing or new requirements or policies, or if we or such third parties are not able to 
maintain regulatory compliance, our current or any future product candidates we may develop may lose any regulatory approval or marketing 
authorizations that may have been obtained and we may not achieve or sustain profitability. For additional information regarding other healthcare 
legislative reform measures, see the section titled “Business—Government Regulation and Product Approval—Healthcare Reform”.

We expect that these and other healthcare reform measures that may be adopted in the future may result in more rigorous coverage criteria and in 

additional downward pressure on the price that we receive for our EUA product and any approved product, which could have an adverse effect on demand 
for our EUA product and other product candidates. Any 

98

 
 
reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The 
implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or 
commercialize our products. 

We are subject to anti-corruption, anti-bribery, anti-money laundering, and similar laws, and non-compliance with such laws can subject us to criminal 
and/or civil liability and harm our business. 

We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the 

U.S. Travel Act and other anti-bribery and anti-money laundering laws in the countries in which we conduct activities. Anti-corruption and anti-bribery 
laws have been enforced aggressively in recent years and are interpreted broadly to generally prohibit companies and their employees and third-party 
intermediaries from authorizing, offering or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We 
interact with officials and employees of government agencies and government-affiliated hospitals, universities and other organizations. In addition, we may 
engage third-party intermediaries to promote our clinical research activities abroad or to obtain necessary permits, licenses and other regulatory approvals. 
We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, collaborators 
and agents, even if we do not explicitly authorize such activities. 

While we have policies and procedures to address compliance with such laws in the United States, we cannot assure you that all of our employees 
and agents will not take actions in violation of our policies and applicable law, for which we may be ultimately held responsible. Detecting, investigating 
and resolving actual or alleged violations can require a significant diversion of time, resources and attention from senior management. In addition, 
noncompliance with anti-corruption, anti-bribery or anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, 
settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, 
suspension and/or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage and other 
collateral consequences. If any subpoenas or investigations are launched, or governmental or other sanctions are imposed, or if we do not prevail in any 
possible civil or criminal litigation, our business, financial condition, results of operations and prospects could be materially harmed. In addition, 
responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense costs and 
other professional fees. Enforcement actions and sanctions could further harm our business, financial condition, results of operations and prospects. 

Risks Related to Our Dependence on Third Parties 

We intend to rely on third parties to produce clinical and commercial supplies of our product candidates. 

We are currently manufacturing material for product candidates of three different modalities: mAbs, HCMV-based vaccines and siRNAs. Except for 

limited process development and quality control testing capabilities in certain of our facilities, we do not own or operate facilities for full process 
development or product manufacturing, storage and distribution, or testing. We are dependent on third parties to develop the manufacturing process and 
manufacture the clinical supplies of our current and any future product candidates. We have established relationships with multiple contract development 
and manufacturing organizations, or CDMOs, that have produced material to support our preclinical, Phase 1, 2, and 3 clinical trials. We have limited 
experience manufacturing our product candidates on a commercial scale, and we do not yet have sufficient information to reliably estimate the cost of the 
commercial manufacturing of our future product candidates. Certain of our product candidates may have to compete with existing and future products, such 
as the annual flu vaccine or any current or future COVID-19 vaccine, that may have a lower price point. The actual cost to manufacture our product 
candidates could materially and adversely affect the commercial viability of our product candidates. 

The facilities used by third-party manufacturers to manufacture our product candidates must be approved by the FDA pursuant to inspections that 
will be conducted after we submit our NDA or BLA to the FDA. We do not control the manufacturing process of, and are completely dependent on, third-
party manufacturers for compliance with the cGMP requirements. If our third-party manufacturers cannot successfully manufacture material that conforms 
to our specifications and the strict regulatory requirements of the FDA or others, we will not be able to secure and/or maintain regulatory approval for our 
product candidates. In addition, we have no control over the ability of our third-party manufacturers to maintain adequate quality control, quality assurance 
and qualified personnel. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product 
candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact 
our ability to develop, obtain regulatory approval for or market our product candidates, if approved. Any significant delay in the supply of a product 

99

 
 
 
 
candidate, or the raw material components thereof, for an ongoing clinical trial due to the need to replace a third-party manufacturer could considerably 
delay completion of our clinical trials, product testing and potential regulatory approval of our product candidates. 

We also intend to rely on third-party manufacturers to supply us with sufficient quantities of our product candidates to be used, if approved, for 

commercialization. There is, however, no assurance that our third-party manufacturers will meet our working assumptions of manufacturing titer and yield 
per batch of our product candidates. Any reduction in anticipated manufacturing titer and yield per batch may adversely impact our ability to meet market 
demand for any approved product. Furthermore, if we are not able to produce supply at low enough costs, it would negatively impact our ability to generate 
revenue, harm our reputation, and could have an adverse effect on our business, financial condition, results of operations and prospects. 

In addition, we currently rely on a strategic collaborator and foreign CDMOs, including a CDMO in China, which we, in part, rely on for the clinical 

development, manufacturing, and commercialization of our proprietary antibodies developed for SARS-CoV-2, and will likely continue to rely on foreign 
CDMOs in the future. Foreign CDMOs may be subject to trade restrictions and other foreign regulatory requirements which could increase the cost or 
reduce the supply of material available to us, delay the procurement of such material or have an adverse effect on our ability to secure significant 
commitments from governments to purchase our potential therapies. 

Additionally, the biopharmaceutical industry in particular in China is strictly regulated by the Chinese government. Changes to Chinese regulations 

or government policies affecting biopharmaceutical companies are unpredictable and may have a material adverse effect on our collaborators in China 
which could have an adverse effect on our business, financial condition, results of operations and prospects. Evolving changes in China’s public health, 
economic, political, and social conditions and the uncertainty around China’s relationship with other governments, such as the United States and the U.K., 
could also negatively impact our ability to manufacture our product candidates for our planned clinical trials or have an adverse effect on our ability to 
secure government funding, which could adversely affect our financial condition and cause us to delay our clinical development programs.

Further, our reliance on third-party suppliers and manufacturers entails risks to which we would not be exposed to if we manufactured product 

candidates ourselves, including: 

•

•

•

•

•

•

•

•

•

•

•

•

•

delay or inability to procure or expand sufficient manufacturing capacity;

delays in process development;

issues related to scale-up of manufacturing;

excess manufacturing capacity due to insufficient market demand for our product candidates and responsibility for the associated costs;

costs and validation of new equipment and facilities required for scale-up;

inability of our third-party manufacturers to execute technology transfers, manufacturing procedures and other logistical support 
requirements appropriately or on a timely basis;

inability to negotiate manufacturing agreements with third parties under commercially reasonable terms, if at all;

breach, termination or nonrenewal of manufacturing agreements with third parties in a manner or at a time that is costly or damaging to us;

reliance on single sources for product raw materials or components;

lack of qualified backup suppliers for those raw materials or components that are currently purchased from a sole or single-source supplier;

lack of ownership to the intellectual property rights to any improvements made by our third-party manufacturers in the manufacturing 
process for our product candidates;

disruptions to operations of our third-party manufacturers or suppliers by conditions unrelated to our business or operations, including the 
bankruptcy of the manufacturer or supplier;

disruptions caused by geopolitical events, including civil or political unrest (such as the ongoing conflict between Ukraine and Russia), 
terrorism, insurrection or war, man-made or natural disasters or public health pandemics or epidemics, including, for example, the ongoing 
COVID-19 pandemic; and

100

 
•

carrier disruptions or increased costs that are beyond our control.

We cannot be sure that single source suppliers for our product raw materials or components will remain in business or that they will not be 

purchased by one of our competitors or another company that is not interested in continuing to produce these raw materials or components for our intended 
purpose. In addition, the lead time needed to establish a relationship with a new supplier can be lengthy and we may experience delays in meeting demand 
in the event we must switch to a new supplier. The time and effort to qualify a new supplier could result in additional costs, diversion of resources or 
reduced manufacturing yields, any of which would negatively impact our operating results. 

Furthermore, there are a limited number of suppliers and manufacturers that supply synthetic siRNAs. Alnylam Pharmaceuticals, Inc., or Alnylam, 
is currently supplying clinical material for our VIR-2218 Phase 1/2 clinical trial through its CDMOs. We will assume responsibility for technology transfer 
and manufacturing ahead of any Phase 3 clinical trials for VIR-2218. Alnylam currently relies on a limited number of suppliers and CDMOs for our supply 
of synthetic siRNAs. There are risks inherent in pharmaceutical manufacturing that could affect the ability of Alnylam and Alnylam’s CDMOs to meet our 
delivery time requirements or provide adequate amounts of synthetic siRNAs to meet our needs. Included in these risks are potential delays or raw 
materials and component shortages including as a result of the ongoing COVID-19 pandemic, synthesis and purification failures and/or contamination 
during the manufacturing process, as well as other issues with the CDMO’s facility and ability to comply with the applicable manufacturing requirements, 
including use of the proper raw materials and components, which could result in unusable product. This would cause delays in our manufacturing timelines 
and ultimately delay our clinical trials and potentially put at risk commercial supply, as well as result in additional expense to us. To fulfill our siRNA 
requirements, we may need to secure alternative suppliers of synthetic siRNAs and/or key raw materials and components, and such alternative suppliers are 
limited and may not be readily available, or we may be unable to enter into agreements with them on reasonable terms and in a timely manner. 

In addition, manufacturers may have little or no experience with viral vector products and therefore may require a significant amount of support 
from us in order to implement and maintain the infrastructure and processes required to manufacture our HCMV vector-based product candidates. The 
challenges to HCMV-based vaccine manufacturing include the large size of the virus, which precludes terminal sterile filtration, and the attenuation of the 
engineered human virus, which dramatically reduces high growth yields during manufacturing. To address these challenges, we have made significant 
internal investments in process development and scale-up, largely funded by grants from the Bill & Melinda Gates Foundation. We have established a 
cGMP process in support of Phase 1 and Phase 2 clinical trials that has been successfully transferred and executed at CDMOs specializing in live vaccine 
manufacturing. However, the existing process will require additional process development and scale-up for later stages of clinical development and 
commercial supply. 

Any of these events could lead to clinical trial delays or failure to obtain regulatory approval or impact our ability to successfully commercialize our 

current or any future product candidates once approved. Some of these events could be the basis for FDA action, including injunction, request for recall, 
seizure or total or partial suspension of production. 

Changes in U.S. and international trade policies, particularly with respect to China, may adversely impact our business and operating results.

The U.S. government has made statements and taken actions in recent years that have led to certain changes and may lead to additional changes to 

U.S. and international trade policies, including imposing several rounds of tariffs affecting certain products manufactured in China. In March 2018, the 
Trump administration announced the imposition of tariffs on steel and aluminum entering the United States and in June 2018 announced further tariffs 
targeting goods imported from China. Both China and the United States have each imposed tariffs indicating the potential for further trade barriers. It is 
unknown whether and to what extent new tariffs (or other new laws or regulations) will be adopted, or the effect that any such actions would have on us or 
our industry, and it is unclear whether the Biden administration will work to reverse these measures or pursue similar policy initiatives. While we have only 
recently started commercialization of sotrovimab under EUA, any unfavorable government policies on international trade, such as export controls, capital 
controls or tariffs, may affect the demand for sotrovimab or our product candidates, the competitive position of sotrovimab or our product candidates, and 
import or export of raw materials and product used in our drug development activities and commercial manufacturing, particularly with respect to raw 
materials and product that we import from China, including pursuant to our manufacturing arrangements with WuXi Biologics. If any new tariffs, export 
controls, legislation and/or regulations are implemented, or if existing trade agreements are renegotiated or, in particular, if the U.S. government takes 
retaliatory trade actions due to the recent U.S.-China trade tension, such changes could have an adverse effect on our business, financial condition and 
results of operations.

101

 
 
Our business involves the use of hazardous materials and we and our third-party manufacturers and suppliers must comply with environmental, health 
and safety laws and regulations, which can be expensive and restrict how we do, or interrupt our, business. 

Our research and development activities and our third-party manufacturers’ and suppliers’ activities involve the generation, storage, use and disposal 

of hazardous materials, including the components of our product candidates and other hazardous compounds and wastes. We and our manufacturers and 
suppliers are subject to environmental, health and safety laws and regulations governing, among other matters, the use, manufacture, generation, storage, 
handling, transportation, discharge and disposal of these hazardous materials and wastes and worker health and safety. In some cases, these hazardous 
materials and various wastes resulting from their use are stored at our and our manufacturers’ facilities pending their use and disposal. We cannot eliminate 
the risk of contamination or injury, which could result in an interruption of our commercialization efforts, research and development efforts and business 
operations, damages and significant cleanup costs and liabilities under applicable environmental, health and safety laws and regulations. We also cannot 
guarantee that the safety procedures utilized by our third-party manufacturers for handling and disposing of these materials and wastes generally comply 
with the standards prescribed by these laws and regulations. We may be held liable for any resulting damages costs or liabilities, which could exceed our 
resources, and state or federal or other applicable authorities may curtail our use of certain materials and/or interrupt our business operations. Furthermore, 
environmental, health and safety laws and regulations are complex, change frequently and have tended to become more stringent. We cannot predict the 
impact of such changes and cannot be certain of our future compliance. Failure to comply with these environmental, health and safety laws and regulations 
may result in substantial fines, penalties or other sanctions. We do not currently carry hazardous waste insurance coverage. 

We rely on third parties to conduct, supervise and monitor our preclinical studies and clinical trials, and if those third parties perform in an 
unsatisfactory manner, it may harm our business. 

We do not currently have the ability to independently conduct any clinical trials. We intend to rely on CROs and clinical trial sites to ensure the 

proper and timely conduct of our preclinical studies and clinical trials, and we expect to have limited influence over their actual performance. We rely on 
CROs to monitor and manage data for our clinical programs, as well as the execution of future preclinical studies. We expect to control only certain aspects 
of our CROs’ activities. Nevertheless, we will be responsible for ensuring that each of our preclinical studies and clinical trials is conducted in accordance 
with the applicable protocol, legal, regulatory and scientific standards, and our reliance on the CROs does not relieve us of our regulatory responsibilities. 

We and our CROs are required to comply with the good laboratory practices, or GLPs, and GCPs, which are regulations and guidelines enforced by 

the FDA and comparable foreign regulatory authorities in the form of International Conference on Harmonization guidelines for any of our product 
candidates that are in preclinical and clinical development. The regulatory authorities enforce GCPs through periodic inspections of trial sponsors, principal 
investigators and clinical trial sites. Although we rely on CROs to conduct GCP-compliant clinical trials, we remain responsible for ensuring that each of 
our GLP preclinical studies and clinical trials is conducted in accordance with its investigational plan and protocol and applicable laws and regulations. If 
we or our CROs fail to comply with GCPs, the clinical data generated in our clinical trials may be deemed unreliable, and the FDA or comparable foreign 
regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. Accordingly, if our CROs fail to 
comply with these regulations or fail to recruit a sufficient number of subjects, we may be required to repeat clinical trials, which would delay the 
regulatory approval process.  

Our reliance on third parties to conduct clinical trials will result in less direct control over the management of data developed through clinical trials 

than would be the case if we were relying entirely upon our own staff. Communicating with CROs and other third parties can be challenging, potentially 
leading to mistakes as well as difficulties in coordinating activities. If our CROs do not successfully carry out their contractual duties or obligations, fail to 
meet expected deadlines or fail to comply with regulatory requirements, or if the quality or accuracy of the clinical data they obtain is compromised due to 
the failure to adhere to our clinical protocols or regulatory requirements or for any other reasons, our clinical trials may be extended, delayed or terminated, 
and we may not be able to obtain regulatory approval for, or successfully commercialize, any product candidate that we develop. As a result, our financial 
results and the commercial prospects for any product candidate that we develop would be harmed, our costs could increase, and our ability to generate 
revenue could be delayed. While we will have agreements governing their activities, our CROs will not be our employees and we will not control whether 
or not they devote sufficient time and resources to our future clinical and preclinical programs. These CROs may also have relationships with other 
commercial entities, including our competitors, for whom they may also be conducting clinical trials or other product development activities which could 
harm our business. We face the risk of potential 

102

 
 
 
unauthorized disclosure or misappropriation of our intellectual property by CROs, which may reduce our trade secret protection and allow our potential 
competitors to access and exploit our proprietary technology. 

If our relationship with any of these CROs terminates, we may not be able to enter into arrangements with alternative CROs or do so on 

commercially reasonable terms. Switching or adding additional CROs involves substantial cost and requires management time and focus. In addition, there 
is a natural transition period when a new CRO commences work. As a result, delays occur, which can negatively impact our ability to meet our desired 
clinical development timelines. While we intend to carefully manage our relationships with our CROs, there can be no assurance that we will not encounter 
challenges or delays in the future or that these delays or challenges will not have a negative impact on our business, financial condition, results of 
operations and prospects. 

In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive 
compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the FDA. The 
FDA may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected interpretation 
of the trial. The FDA may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself 
may be jeopardized. This could result in a delay in approval or rejection of our marketing applications by the FDA and may ultimately lead to the denial of 
marketing approval of our product candidates. 

Risks Related to Our Intellectual Property

If we breach our license agreements or any of the other agreements under which we acquired, or will acquire, the intellectual property rights to our 
product candidates, we could lose the ability to continue the development and commercialization of the related product candidates. 

We license a number of technologies to form our antibody platform and T cell platform, and the technology we use in our siRNA platform is 
licensed from Alnylam. We have also developed certain product candidates using intellectual property licensed from third parties. A core element of our 
business strategy includes continuing to acquire or in-license additional technologies or product candidates for the treatment and prevention of serious 
infectious diseases. 

If we fail to meet our obligations under these agreements, our licensors may have the right to terminate our licenses. If any of our license agreements 

are terminated, and we lose our intellectual property rights under such agreements, this may result in a complete termination of our product development 
and any commercialization efforts for the product candidates which we are developing under such agreements. While we would expect to exercise all rights 
and remedies available to us, including seeking to cure any breach by us, and otherwise seek to preserve our rights under such agreements, we may not be 
able to do so in a timely manner, at an acceptable cost or at all. We may also be subject to risks related to disputes between us and our licensors regarding 
the intellectual property subject to a license agreement.

If we are unable to obtain and maintain patent protection for our product candidates and technology, or if the scope of the patent protection obtained is 
not sufficiently broad or robust, our competitors could develop and commercialize products and technology similar or identical to ours, and our ability 
to successfully commercialize our product candidates and technology may be adversely affected. 

Our success depends, in large part, on our ability to obtain and maintain patent protection in the United States and other countries with respect to our 

product candidates and our technology. We and our licensors have sought, and intend to seek, to protect our proprietary position by filing patent 
applications in the United States and abroad related to our product candidates and our technology that are important to our business. 

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and 

has, in recent years, been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights 
are highly uncertain. Our pending and future patent applications may not result in patents being issued which protect our technology or product candidates 
or which effectively prevent others from commercializing competitive technologies and product candidates. Because patent applications in the United 
States and most other countries are confidential for a period of time after filing, and some remain so until issued, we cannot be certain that we or our 
licensors were the first to file a patent application relating to any particular aspect of a product candidate. Furthermore, if third parties have filed such 
patent applications with a priority date before March 16, 2013, an interference proceeding in the United States can be initiated by such third party, or by the 
U.S. Patent and 

103

 
 
 
 
Trademark Office, or USPTO, itself, to determine who was the first to invent any of the subject matter covered by the patent claims of our applications.

The patent prosecution process is expensive, time-consuming and complex, and we may not be able to file, prosecute, maintain, enforce or license 
all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of 
our research and development output before it is too late to obtain patent protection. In addition, changes in either the patent laws or interpretation of the 
patent laws in the United States could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or 
defense of issued patents. Similarly, changes in patent law and regulations in other countries or jurisdictions, changes in the governmental bodies that 
enforce them or changes in how the relevant governmental authority enforces patent laws or regulations may weaken our ability to obtain new patents or to 
enforce patents that we own or have licensed or that we may obtain in the future.

We or our licensors have not pursued or maintained, and may not pursue or maintain in the future, patent protection for our product candidates in 

every country or territory in which we may sell our products, if approved. In addition, the laws of some foreign countries do not protect intellectual 
property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from infringing 
our patents in all countries outside the United States, or from selling or importing products that infringe our patents in and into the United States or other 
jurisdictions. 

Moreover, the coverage claimed in a patent application can be significantly reduced before the patent is issued and its scope can be reinterpreted 

after issuance. Even if the patent applications we license or own do issue as patents, they may not issue in a form that will provide us with any meaningful 
protection, prevent competitors or other third parties from competing with us or otherwise provide us with any competitive advantage. Our competitors or 
other third parties may be able to circumvent our patents by developing similar or alternative products in a non-infringing manner. 

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our patents may be challenged in the courts or 

patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or in patent claims being narrowed, invalidated or held 
unenforceable, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration 
of the patent protection of our technology and product candidates. Given the amount of time required for the development, testing and regulatory review of 
new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our 
intellectual property may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours. In addition, if 
the breadth or strength of protection provided by the patents and patent applications we hold with respect to our product candidates is threatened, it could 
dissuade companies from collaborating with us to develop, and threaten our ability to commercialize, our product candidates, or could result in licensees 
seeking release from their license agreements. 

Furthermore, our owned and in-licensed patents may be subject to a reservation of rights by one or more third parties. For example, the research 

resulting in certain of our owned and in-licensed patent rights and technology was funded in part by the U.S. government. As a result, the government may 
have certain rights, or march-in rights, to such patent rights and technology. When new technologies are developed with government funding, the 
government generally obtains certain rights in any resulting patents, including a nonexclusive license authorizing the government to use the invention for 
noncommercial purposes. These rights may permit the government to disclose our confidential information to third parties and to exercise march-in rights 
to use or allow third parties to use our licensed technology. The government can exercise its march-in rights if it determines that action is necessary because 
we fail to achieve practical application of the government-funded technology, because action is necessary to alleviate health or safety needs, to meet 
requirements of federal regulations, or to give preference to U.S. industry. In addition, our rights in such inventions may be subject to certain requirements 
to manufacture products embodying such inventions in the United States. Any exercise by the government of such rights could harm our competitive 
position, business, financial condition, results of operations and prospects. 

Obtaining and maintaining our patent rights depends on compliance with various procedural, document submission, fee payment and other 
requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for noncompliance with these 
requirements. 

The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and 

other similar provisions during the patent application process. In addition, periodic maintenance fees, renewal fees, annuity fees and various other 
government fees on patents and/or patent applications will 

104

 
 
have to be paid to the USPTO and various government patent agencies outside the United States over the lifetime of our owned and licensed patents and/or 
applications and any patent rights we may own or license in the future. We rely on our service providers or our licensors to pay these fees. The USPTO and 
various non-U.S. government patent agencies require compliance with several procedural, documentary, fee payment and other similar provisions during 
the patent application process. We employ reputable law firms and other professionals to help us comply, and we are also dependent on our licensors to take 
the necessary action to comply with these requirements with respect to our licensed intellectual property. Noncompliance events that could result in 
abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, 
nonpayment of fees and failure to properly legalize and submit formal documents. If we or our licensors fail to maintain the patents and patent applications 
covering our product candidates or technologies, including as a result of geopolitical events such as civil or political unrest (including the ongoing conflict 
between Ukraine and Russia), we may not be able to use such patents and patent applications or stop a competitor from marketing products that are the 
same as or similar to our product candidates, which would have an adverse effect on our business. In many cases, an inadvertent lapse can be cured by 
payment of a late fee or by other means in accordance with the applicable rules. There are situations, however, in which noncompliance can result in 
abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, 
potential competitors might be able to enter the market and this circumstance could harm our business. 

In addition, if we fail to apply for applicable patent term extensions or adjustments, we will have a more limited time during which we can enforce 
our granted patent rights. In addition, if we are responsible for patent prosecution and maintenance of patent rights in-licensed to us or out-licensed by us, 
any of the foregoing could expose us to liability to the applicable patent owner or licensee, respectively. 

Patent terms may be inadequate to protect our competitive position on our product candidates or any products approved in the future for an adequate 
amount of time and additional competitors could enter the market with generic or biosimilar versions of such products. 

Patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after its first effective filing date. 
Although various extensions may be available, the life of a patent and the protection it affords is limited. In addition, although upon issuance in the United 
States a patent’s life can be increased based on certain delays caused by the USPTO, this increase can be reduced or eliminated based on certain delays 
caused by the patent applicant during patent prosecution. If we do not have sufficient patent life to protect our products, our business and results of 
operations could be adversely affected. 

Given the amount of time required for the development, testing and regulatory review of our product candidates, patents protecting such candidates 
might expire before or shortly after such candidates are commercialized. We expect to seek extensions of patent terms in the United States and, if available, 
in other countries where we have or will obtain patent rights. In the United States, the Hatch-Waxman Act permits a patent term extension of up to five 
years beyond the normal expiration of the patent, provided that the patent is not enforceable for more than 14 years from the date of drug approval, which is 
limited to the approved indication (or any additional indications approved during the period of extension). Furthermore, only one patent per approved 
product can be extended and only those claims covering the approved product, a method for using it or a method for manufacturing it may be extended. 
However, the applicable authorities, including the FDA and the USPTO in the United States, and any equivalent regulatory authority in other countries, 
may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions to our patents, or may grant more limited 
extensions than we request. If this occurs, our competitors may be able to take advantage of our investment in development and clinical trials by 
referencing our clinical and preclinical data and launch their product earlier than might otherwise be the case. 

Also, there are detailed rules and requirements regarding the patents that may be submitted to the FDA for listing in the FDA publication, 

“Approved Drug Products with Therapeutic Equivalence Evaluations,” known as the Orange Book. We may be unable to obtain patents covering our 
product candidates that contain one or more claims that satisfy the requirements for listing in the Orange Book. Even if we submit a patent for listing in the 
Orange Book, the FDA may decline to list the patent, or a manufacturer of generic drugs may challenge the listing. If one of our product candidates is 
approved and a patent covering that product candidate is not listed in the Orange Book, a manufacturer of generic drugs would not have to provide advance 
notice to us of any ANDA filed with the FDA to obtain permission to sell a generic version of such product candidate. We cannot predict which, if any, 
patents in our current portfolio or patents we may obtain in the future will be eligible for listing in the Orange Book, how any generic competitor would 
address such patents, whether we would sue on any such patents or the outcome of any such suit. For additional information regarding the Hatch-Waxman 
Act and exclusivity, see the section titled “Business—Government Regulation and Product Approval.”

105

 
We may not be successful in securing or maintaining proprietary patent protection for products and technologies we develop or license. Moreover, if 

any of our owned or in-licensed patents are successfully challenged by litigation, the affected product could immediately face competition and its sales 
would likely decline rapidly. Any of the foregoing could harm our competitive position, business, financial condition, results of operations and prospects.

Third parties may initiate legal proceedings alleging that we are infringing, misappropriating or otherwise violating their intellectual property rights, 
the outcome of which would be uncertain and could have a negative impact on the success of our business. 

Our commercial success depends, in part, upon our ability and the ability of others with whom we may collaborate to develop, manufacture, market 
and sell our current and any future product candidates and use our proprietary technologies without infringing, misappropriating or otherwise violating the 
proprietary rights and intellectual property of third parties. The biotechnology and pharmaceutical industries are characterized by extensive and complex 
litigation regarding patents and other intellectual property rights. Numerous U.S. and foreign issued patents and pending patent applications, which are 
owned by third parties, exist in the fields in which we are developing our EUA product and other product candidates. As the biotechnology and 
pharmaceutical industries expand and more patents are issued, the risk increases that our EUA product and other product candidates may give rise to claims 
of infringement of the patent rights of others. We may in the future become party to, or be threatened with, adversarial proceedings or litigation regarding 
intellectual property rights with respect to our current and any future product candidates and technology, including interference proceedings, derivation 
proceedings, post grant review and inter-partes review before the USPTO. If we are found to infringe a third party’s valid and enforceable intellectual 
property rights, we could be required to obtain a license from such third party to continue developing, manufacturing and marketing our product 
candidate(s) and technology. Under any such license, we would most likely be required to pay various types of fees, milestones, royalties or other amounts. 
Moreover, we may not be able to obtain any required license on commercially reasonable terms or at all, and if such an instance arises, our ability to 
commercialize our product candidates may be impaired or delayed, which could in turn significantly harm our business. Parties making claims against us 
may also seek and obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize our EUA 
product or other product candidates. 

The licensing or acquisition of third-party intellectual property rights is a competitive area, and more established companies may also pursue 
strategies to license or acquire third-party intellectual property rights that we may consider attractive or necessary. These established companies may have a 
competitive advantage over us due to their size, capital resources and greater clinical development and commercialization capabilities. In addition, 
companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party 
intellectual property rights on terms that would allow us to make an appropriate return on our investment or at all. If we are unable to successfully obtain 
rights to required third-party intellectual property rights or maintain the existing intellectual property rights we have, we may have to abandon development 
of the relevant program or product candidate, which could have an adverse effect on our business, financial condition, results of operations and prospects. 
Furthermore, even if we were able to obtain a license, it could be nonexclusive, thereby giving our competitors and other third parties access to the same 
technologies licensed to us, and it could require us to make substantial licensing and royalty payments. We could be forced, including by court order, to 
cease developing, manufacturing and commercializing the infringing technology or product candidate. We may also have to redesign our products, which 
may not be commercially or technically feasible or require substantial time and expense. In addition, we could be found liable for monetary damages, 
including treble damages and attorneys’ fees, if we are found to have willfully infringed a patent or other intellectual property right. We may be required to 
indemnify collaborators or contractors against such claims. A finding of infringement could prevent us from manufacturing and commercializing our EUA 
product or current or any future product candidates or force us to cease some or all of our business operations, which could harm our business. Even if we 
are successful in defending against such claims, litigation can be expensive and time-consuming and would divert management’s attention from our core 
business. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some 
of our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results 
of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have an 
adverse effect on the price of our common stock. 

Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our 

business, financial condition, results of operations and prospects. 

We may be subject to claims asserting that our employees, consultants or advisors have wrongfully used or disclosed alleged trade secrets of their 
current or former employers or claims asserting ownership of what we regard as our own intellectual property. 

106

 
 
 
Certain of our employees, consultants or advisors are currently, or were previously, employed at universities or other biotechnology or 

pharmaceutical companies, including our competitors or potential competitors. Although we try to ensure that our employees, consultants and advisors do 
not use the proprietary information or know-how of others in their work for us, we may be subject to claims that these individuals or we have used or 
disclosed intellectual property, including trade secrets or other proprietary information, of any such individual’s current or former employer. Litigation may 
be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable 
intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a 
distraction to management. 

In addition, we may in the future be subject to claims by our former employees or consultants asserting an ownership right in our patents or patent 

applications as a result of the work they performed on our behalf. For example, we may have inventorship disputes arise from conflicting obligations of 
consultants or others who are involved in developing our product candidates. Although it is our policy to require our employees and contractors who may 
be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be 
unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own, and we 
cannot be certain that our agreements with such parties will be upheld in the face of a potential challenge or that they will not be breached, for which we 
may not have an adequate remedy. The assignment of intellectual property rights may not be self-executing or the assignment agreements may be breached, 
and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard 
as our intellectual property. 

We may be involved in lawsuits to protect or enforce our patents, the patents of our licensors or our other intellectual property rights, which could be 
expensive, time-consuming and unsuccessful. 

Competitors may infringe, misappropriate or otherwise violate our patents, the patents of our licensors or our other intellectual property rights. To 

counter infringement or unauthorized use, we may be required to file legal claims, which can be expensive and time-consuming and are likely to divert 
significant resources from our core business, including distracting our technical and management personnel from their normal responsibilities. 

In addition, in an infringement proceeding, a court may decide that a patent of ours or our licensors is not valid or is unenforceable, or may refuse to 

stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any 
litigation or defense proceedings could put one or more of our owned or licensed patents at risk of being invalidated or interpreted narrowly and could put 
our owned or licensed patent applications at risk of not issuing. The initiation of a claim against a third party might also cause the third party to bring 
counterclaims against us, such as claims asserting that our patent rights are invalid or unenforceable. In patent litigation in the United States, defendant 
counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several 
statutory requirements, including lack of novelty, obviousness, non-enablement or lack of statutory subject matter. Grounds for an unenforceability 
assertion could be an allegation that someone connected with prosecution of the patent withheld relevant material information from the USPTO, or made a 
materially misleading statement, during prosecution. Third parties may also raise similar validity claims before the USPTO in post-grant proceedings such 
as ex parte reexaminations, inter-partes review, post-grant review, or oppositions or similar proceedings outside the United States, in parallel with litigation 
or even outside the context of litigation. Third parties may also challenge inventorship through a derivation proceeding or other litigation proceeding 
challenging inventorship, which can include claims of misappropriation of intellectual property, filing a patent application without authorization of the true 
inventor, not listing inventors, or listing non-inventors as inventors. The outcome following legal assertions of invalidity and unenforceability is 
unpredictable. We cannot be certain that there is or will be no invalidating prior art, of which we and the patent examiner were unaware during prosecution. 
For the patents and patent applications that we have licensed, we may have limited or no right to participate in the defense of any licensed patents against 
challenge by a third party. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of 
any future patent protection on our current or future product candidates. Such a loss of patent protection could harm our business. 

We may not be able to prevent, alone or with our licensors, misappropriation of our intellectual property rights, particularly in countries where the 

laws may not protect those rights as fully as in the United States. Our business could be harmed if in litigation the prevailing party does not offer us a 
license, or if the license offered as a result is not on commercially reasonable terms. Any litigation or other proceedings to enforce our intellectual property 
rights may fail and, even if successful, may result in substantial costs and distract our management and other employees. 

107

 
 
Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of 
our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results of 
hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have an 
adverse effect on the price of our common stock.

We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able 

to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources and more mature and 
developed intellectual property portfolios. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or 
misappropriating or from successfully challenging our intellectual property rights. Uncertainties resulting from the initiation and continuation of patent 
litigation or other proceedings could have an adverse effect on our ability to compete in the marketplace. 

We may not be able to protect our intellectual property rights throughout the world, which could negatively impact our business. 

Filing, prosecuting and defending patents covering our current and any future product candidates and technology platforms in all countries 
throughout the world would be prohibitively expensive. Competitors may use our technologies in jurisdictions where we or our licensors have not obtained 
patent protection to develop their own products and, further, may export otherwise infringing products to territories where we may obtain patent protection 
but where patent enforcement is not as strong as that in the United States. These products may compete with our products in jurisdictions where we do not 
have any issued or licensed patents, and any future patent claims or other intellectual property rights may not be effective or sufficient to prevent them from 
so competing. 

Issued patents may be challenged by third parties in the courts or patent offices in various countries throughout the world. Invalidation proceedings 

may result in patent claims being narrowed, invalidated or held unenforceable. Uncertainties regarding the outcome of such proceedings, as well as any 
resulting losses of patent protection, could harm our business. 

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal 

systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property 
protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of 
competing products in violation of our intellectual property and proprietary rights generally. Proceedings to enforce our intellectual property and 
proprietary rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put 
our patents at risk of being invalidated or interpreted narrowly, could put our patent applications at risk of not issuing, and could provoke third parties to 
assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially 
meaningful. Accordingly, our efforts to enforce our intellectual property and proprietary rights around the world may be inadequate to obtain a significant 
commercial advantage from the intellectual property that we develop or license.

Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. Some countries do 

not enforce patents related to medical treatments, or limit enforceability in the case of a public emergency. In addition, many countries limit the 
enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which 
could materially diminish the value of such patent. If we or any of our licensors is forced to grant a license to third parties with respect to any patents 
relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations and prospects may be 
adversely affected.

If the U.S. government, the World Trade Organization, or WTO, or other governmental body imposes an intellectual property rights waiver, our ability 
to successfully commercialize our COVID-19 product candidates and protect our related technology could be adversely affected.

The WTO is currently considering a waiver of intellectual property rights for COVID-19 vaccines and the U.S. government recently took a stance in 

support of the waiver. The current proposal is for a temporary waiver of intellectual property rights that cover COVID-19 vaccines, however, the ultimate 
timing and scope of the waiver, if approved, is unknown. The scope and timing of such waiver will likely be subject to extensive negotiations given the 
complexity of the matter, which may result in prolonged uncertainty, which could adversely affect our business. If a waiver is approved and 

108

 
 
 
covers COVID-19 treatments or prophylactics, such as sotrovimab and VIR-7832, our ability to successfully commercialize our COVID-19 product 
candidates and protect our related technology could be adversely affected. 

The current waiver proposal is the result of public health concerns from the COVID-19 pandemic and an effort to make vaccines more widely 
available worldwide. This proposal may also lead to similar waivers of intellectual property rights in the future in connection with other public health 
pandemics or epidemics or other situations of public health concern. Given that our business is focused on treating and preventing infectious diseases, there 
is a risk that our business and our ability to protect our technology could be adversely affected in situations beyond COVID-19.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patent and trademark protection for our product candidates, we also rely on trade secrets, including unpatented know-how, 

technology and other proprietary information, to maintain our competitive position. Because we rely on third parties to help us discover, develop and 
manufacture our current and any future product candidates, or if we collaborate with third parties for the development, manufacturing or commercialization 
of our current or any future product candidates, we must, at times, share trade secrets with them. We may also conduct joint research and development 
programs that may require us to share trade secrets under the terms of our research and development collaborations or similar agreements. 

We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if applicable, material transfer agreements, 

consulting agreements or other similar agreements with our advisors, employees, third-party contractors and consultants prior to beginning research or 
disclosing proprietary information. These agreements typically limit the rights of these parties to use or disclose our confidential information, including our 
trade secrets. We also enter into invention or patent assignment agreements with our employees, advisors and consultants. Despite our efforts to protect our 
trade secrets, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, 
are inadvertently incorporated into the technology of others or are disclosed or used in violation of these agreements. Moreover, we cannot guarantee that 
we have entered into such agreements with each party that may have or have had access to our confidential information or proprietary technology and 
processes. Monitoring unauthorized uses and disclosures is difficult, and we do not know whether the steps we have taken to protect our proprietary 
technologies will be effective. If any of the collaborators, scientific advisors, employees, contractors and consultants who are parties to these agreements 
breaches or violates the terms of any of these agreements, we may not have adequate remedies for any such breach or violation, and we could lose our trade 
secrets as a result. Moreover, if confidential information that is licensed or disclosed to us by our partners, collaborators or others is inadvertently disclosed 
or subject to a breach or violation, we may be exposed to liability to the owner of that confidential information. Enforcing a claim that a third-party illegally 
or unlawfully obtained and is using our trade secrets, like patent litigation, is expensive and time-consuming, and the outcome is unpredictable. In addition, 
courts outside the United States are sometimes less willing to protect trade secrets. 

In addition, our competitors may independently develop knowledge, methods and know-how equivalent to our trade secrets. Competitors could 
purchase our products and replicate some or all of the competitive advantages we derive from our development efforts for technologies on which we do not 
have patent protection. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to 
prevent them, or those to whom they communicate it, from using that technology or information to compete with us. Given that our proprietary position is 
based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other unauthorized use or disclosure could have an 
adverse effect on our business, financial condition, results of operations and prospects. 

We also seek to preserve the integrity and confidentiality of our data and other confidential information by maintaining physical security of our 

premises and physical and electronic security of our information technology systems. Additionally, the risk of cyber-attacks or other privacy or data 
security incidents may be heightened as a result of our moving increasingly towards a remote working environment, which may be less secure and more 
susceptible to hacking attacks. While we have confidence in these individuals, organizations and systems, agreements or security measures may be 
breached, and detecting the disclosure or misappropriation of confidential information and enforcing a claim that a party illegally disclosed or 
misappropriated confidential information is difficult, expensive and time-consuming, and the outcome is unpredictable. Further, we may not be able to 
obtain adequate remedies for any breach. In addition, our confidential information may otherwise become known or be independently discovered by 
competitors, in which case we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to 
compete with us. 

Any trademarks we may obtain may be infringed or successfully challenged, resulting in harm to our business. 

109

 
 
We rely and expect to continue to rely on trademarks as one means to distinguish any of our products and product candidates that are approved for 

marketing from the products of our competitors. Additionally, the process of obtaining trademark protection is expensive and time-consuming, and we may 
not be able to prosecute all necessary or desirable trademark applications at a reasonable cost or in a timely manner or obtain trademark protection in all 
jurisdictions that we consider to be important to our business. Once we select trademarks and apply to register them, our trademark applications may not be 
approved. Third parties may oppose our trademark applications or otherwise challenge our use of the trademarks. In the event that our trademarks are 
successfully challenged, we could be forced to rebrand our products, which could result in loss of brand recognition and could require us to devote 
resources to advertising and marketing new brands. Our competitors may infringe our trademarks, and we may not have adequate resources to enforce our 
trademarks. 

In addition, any proprietary product name we propose to use with our current or any other product candidate in the United States must be approved 

by the FDA, regardless of whether we have registered it, or applied to register it, as a trademark. The FDA typically conducts a review of proposed product 
names, including an evaluation of the potential for confusion with other product names. If the FDA objects to any of our proposed proprietary product 
names, we may be required to expend significant additional resources in an effort to identify a suitable proprietary product name that would qualify under 
applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA.

The exercise by the Bill & Melinda Gates Foundation of its licenses to certain of our intellectual property and its development and commercialization 
of products that we are also developing and commercializing could have an adverse impact on our market position. 

We entered into an amended and restated letter agreement with the Bill & Melinda Gates Foundation, or the Gates Agreement, in January 2022, 

which amends and restates the letter agreement with the Billi & Melinda Gates Foundation that we entered into in December 2016. In connection with the 
Gates Agreement, the Bill & Melinda Gates Foundation  purchased $20.0 million of shares of our convertible preferred stock and purchased $40.0 million 
of shares of our common stock. We are obligated to use the proceeds of the Bill & Melinda Gates Foundation’s investment in furtherance of its charitable 
purposes to perform certain activities set forth in the Gates Agreement. For additional information regarding our obligations under the Gates Agreement, 
see the section titled “Business—Our Collaboration, License and Grant Agreements—Amended and Restated Letter Agreement with the Bill & Melinda 
Gates Foundation.” 

If we fail to comply with (i) our obligations to use the proceeds of the Bill & Melinda Gates Foundation’s investment for the purposes described in 
the paragraph above and to not use such proceeds for specified prohibited uses, (ii) specified reporting requirements or (iii) specified applicable laws, or if 
we materially breach our specified global access commitments (any such failure or material breach, a specified default), we will be obligated to redeem or 
arrange for a third party to purchase all of our stock purchased by the Bill & Melinda Gates Foundation under the Gates Agreement, at the Bill & Melinda 
Gates Foundation’s request, at a price equal to the greater of (1) the original purchase price or (2) the fair market value, which amount may increase in the 
event of a sale of our company or all of our material assets relating to the Gates Agreement. Additionally, if a specified default occurs or if we are unable or 
unwilling to continue the HIV program, tuberculosis program, vaccinal antibody program or, if applicable, the mutually agreed additional program (except 
for scientific or technical reasons), or if we institute bankruptcy or insolvency proceedings, then the Bill & Melinda Gates Foundation will have the right to 
exercise a non-exclusive, fully-paid license (with the right to sublicense) under our intellectual property to the extent necessary to use, make and sell 
products arising from such programs, in each case solely to the extent necessary to benefit people in the developing countries in furtherance of the Bill & 
Melinda Gates Foundation’s charitable purpose. 

The exercise by the Bill & Melinda Gates Foundation of any of its non-exclusive licenses to certain of our intellectual property (or its right to obtain 

such licenses), and its development and commercialization of product candidates and products that we are also developing and commercializing, could 
have an adverse impact on our market position. 

Risks Related to Our Business Operations, Employee Matters and Managing Growth 

We are highly dependent on our key personnel, and if we are not able to retain these members of our management team or recruit and retain additional 
management, clinical and scientific personnel, our business will be harmed. 

We are highly dependent on our management, scientific and medical personnel, including our Chief Executive Officer, Dr. Scangos. Our key 
personnel may currently terminate their employment with us at any time. The loss of the services of any of these persons could impede the achievement of 
our research, development and commercialization objectives. 

110

 
 
 
 
Additionally, we do not currently maintain “key person” life insurance on the lives of our executives or any of our employees. 

Recruiting and retaining other senior executives, qualified scientific and clinical personnel and, if we progress the development of any of our 

product candidates, commercialization, manufacturing and sales and marketing personnel, will be critical to our success. The loss of the services of our 
executive officers or other key employees could impede the achievement of our research, development and commercialization objectives and seriously 
harm our ability to successfully implement our business strategy. Furthermore, replacing executive officers and key employees may be difficult and may 
take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to 
successfully develop, gain regulatory approval of and commercialize our product candidates. Competition to hire from this limited pool is intense, and we 
may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and 
biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and 
research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and 
development and commercialization strategy. Our consultants and advisors may have commitments under consulting or advisory contracts with other 
entities that may limit their availability to us. If we are unable to continue to attract and retain high-quality personnel, our ability to pursue our growth 
strategy will be limited. 

Our future performance will also depend, in part, on our ability to successfully integrate newly hired executive officers into our management team 

and our ability to develop an effective working relationship among senior management. Our failure to integrate these individuals and create effective 
working relationships among them and other members of management could result in inefficiencies in the development and commercialization of our 
product candidates, harming future regulatory approvals, sales of our product candidates and our results of operations. 

We have in the past and may in the future acquire or invest in other companies or technologies, which could divert our management’s attention, result 
in dilution to our stockholders and otherwise disrupt our operations and adversely affect our operating results. 

We have in the past and may in the future seek to acquire or invest in additional businesses and/or technologies that we believe complement or 
expand our product candidates, enhance our technical capabilities or otherwise offer growth opportunities in the United States and internationally. The 
pursuit of potential acquisitions and investments may divert the attention of management and cause us to incur various expenses in identifying, 
investigating and pursuing suitable acquisitions, whether or not they are consummated. In addition, we are exposed to market risks related to our 
investments, including changes in fair value of equity securities we hold, which is discussed in greater detail under Item 7A. Quantitative and Qualitative 
Disclosures About Market Risk.

For example, we acquired TomegaVax, Inc., or TomegaVax, in September 2016, Humabs BioMed SA, or Humabs, in August 2017, Agenovir 
Corporation, or Agenovir, in January 2018 and Statera Health, LLC, or Statera, in February 2018. Realizing the benefits of these acquisitions will depend 
upon the successful integration of the acquired technology into our existing and future product candidates. Furthermore, we may not be able to integrate the 
acquired personnel, operations and technologies successfully, or effectively manage the combined business following the acquisition. We also may not 
realize the anticipated benefits from any acquired business. We face many risks in connection with acquisitions and investments, whether or not 
consummated. A significant portion of the purchase price of companies we acquire may be allocated to acquired goodwill and other intangible assets, 
which must be assessed for impairment at least annually. If our acquisitions do not yield expected returns, we may in the future be required to take charges 
to our operating results based on this impairment assessment process, which could adversely affect our business, financial condition, results of operations 
and prospects. 

In addition, in connection with our acquisitions of TomegaVax, Humabs and Agenovir, we are required to make future contingent payments upon the 

achievement of certain milestones. We may in the future be required to make these payments, which could adversely affect our financial condition. For 
additional information regarding our obligations under these agreements, see the section titled “Business—Our Acquisition Agreements”.

Furthermore, acquisitions could also result in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect our 

operating results. In addition, if an acquired business fails to meet our expectations, our business, financial condition, results of operations and prospects 
may suffer. We cannot assure you that we will be successful in integrating the businesses or technologies we may acquire. The failure to successfully 
integrate these businesses could have a material adverse effect on our business, financial condition, results of operations and prospects. 

111

 
 
We have experienced significant growth in our organization in recent years and expect to continue to expand, and we may experience difficulties in 
managing this growth, which could disrupt our operations.

As of December 31, 2021, we had 444 full-time employees, an increase of 117 employees compared to December 31, 2020. We have experienced 
significant growth in the number of our employees and the scope of our operations in recent years, particularly in the areas of research, development and 
regulatory affairs, and we expect to continue to experience growth as the clinical development of our product candidates progresses. In addition, if any of 
our product candidates receives marketing approval, we will need to build out our sales and marketing capabilities, either on our own or with others. To 
manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our 
facilities, and continue to recruit and train additional qualified personnel all within the context of the rapidly evolving global pandemic of COVID-19. We 
continue to closely monitor the COVID-19 pandemic and will evolve our expansion plans as needed. As a result of the global pandemic, the majority of our 
workforce has been working from home since March 2020. Despite this, we must continue to effectively integrate, develop and motivate a growing number 
of new employees, and maintain the beneficial aspects of our corporate culture. We have implemented plans to reopen our offices to allow employees to 
return when appropriate. Although these plans are consistent with local government requirements, and focused on employee safety, and contemplate 
returning to remote work should the COVID-19 situation change, there is uncertainty regarding the long-term impact that the COVID-19 pandemic has had 
on the nature of the office environment and remote working, which could present operational and workplace culture challenges as we seek to expand our 
organization. The expansion of our operations may lead to significant costs and may divert our management and business development resources. We may 
not be able to effectively manage the expansion of our operations, recruit and train additional qualified personnel, or succeed at effectively integrating 
employees that have joined during the global pandemic. Any inability to manage growth could delay the execution of our business plans or disrupt our 
operations.  

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses. 

Our operations, and those of our CDMOs, CROs and other contractors and consultants, could be subject to earthquakes, power shortages, 

telecommunications failures, water shortages, floods, hurricanes, typhoons, fires, extreme weather conditions, public health pandemics or epidemics 
(including, for example, the ongoing COVID-19 pandemic), geopolitical events, including civil or political unrest (such as the ongoing conflict between 
Ukraine and Russia), terrorism, insurrection or war, and other natural or man-made disasters or business interruptions, for which we are predominantly self-
insured. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs and 
expenses. 

Our ability to develop our product candidates could be disrupted if our operations or those of our suppliers are affected by geopolitical events, man-
made or natural disasters or other business interruptions. Our corporate headquarters are located in California near major earthquake faults and fire zones. 
The ultimate impact on us, our significant suppliers and our general infrastructure of being located near major earthquake faults and fire zones and being 
consolidated in certain geographical areas is unknown, but our operations and financial condition could suffer in the event of a major earthquake, fire or 
other natural disaster. 

Our business could be materially adversely affected by the effects of health pandemics or epidemics, including the current outbreak of COVID-19 
pandemic and future outbreaks of the disease. 

Our business could be materially adversely affected by the effects of health pandemics or epidemics, including the current COVID-19 pandemic, the 
multiple SARS-CoV-2 variants that have further complicated the fight to subdue the global pandemic and any future outbreaks of the disease. The COVID-
19 pandemic has resulted in travel restrictions, quarantines orders and other restrictions by governments to reduce the spread of the disease. As a result, the 
majority of our workforce has been working from home since March 2020. 

The effects of the restrictions related to the COVID-19 pandemic and our work-from-home policies, including the evolving nature of such policies, 
may negatively impact productivity, disrupt our business and delay our clinical programs and timelines, the magnitude of which will depend, in part, on the 
length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. In addition, due to the COVID-19 
pandemic and our remote workforce, we have experienced an increased risk to our information technology assets and data. We have implemented plans to 
reopen our offices when appropriate. We may face several challenges or disruptions upon a return back to the workplace, including re-integration 
challenges by our employees and distractions to management related to such transition. These and 

112

 
 
 
 
similar, and perhaps more severe, disruptions in our operations could negatively impact our business, operating results and financial condition.

Quarantines, shelter-in-place and similar government orders, or the perception that such orders or other restrictions on the conduct of business 
operations could occur, related to COVID-19 or other infectious diseases could impact personnel at third-party manufacturing facilities in the United States 
and other countries, or the availability or cost of materials, which would disrupt our supply chain. In particular, some of our CDMOs that we use to supply 
our early-stage product candidates are located in China, where the COVID-19 outbreak was first reported and where there have been government-imposed 
quarantines. While many of these materials may be obtained by more than one supplier, including suppliers outside of China, port closures and other 
restrictions resulting from the COVID-19 outbreak in the region or other regions may disrupt our supply chain or limit our ability to obtain sufficient 
materials for our product candidates.

In addition, our clinical trials have been affected by the ongoing COVID-19 pandemic. Site initiation and patient enrollment has been and may be 
further delayed due to prioritization of hospital resources toward the COVID-19 pandemic, and some patients may not be able or willing to comply with 
clinical trial protocols if quarantines impede patient movement or interrupt healthcare services. Similarly, our ability to recruit and retain patients and 
principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19, has been delayed or disrupted, which has 
adversely impacted our clinical trial operations. 

The continued spread of COVID-19, which has caused a broad impact globally, may materially affect us economically. While the potential 

economic impact brought by, and the duration of, the COVID-19 pandemic, may be difficult to assess or predict, it has already resulted in significant 
disruption of global financial markets. This disruption, if sustained or recurrent, could make it more difficult for us to access capital, which could in the 
future negatively affect our liquidity. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our 
business and the value of our common stock.

The global pandemic of COVID-19 and the evolution of new and existing variants of COVID-19 that are resistant to existing treatments or 

vaccinations continue to rapidly evolve. The ultimate impact of the ongoing COVID-19 pandemic or a similar health pandemic or epidemic is highly 
uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, our clinical trials, healthcare systems or 
the global economy as a whole. These effects could have a material impact on our operations, and we will continue to monitor the COVID-19 situation 
closely.

If our information systems, or those maintained on our behalf, fail or suffer security breaches, such events could result in, without limitation, the 
following: a significant disruption of our product development programs; an inability to operate our business effectively; unauthorized access to or 
disclosure of the personal information we process; and other adverse effects on our business, financial condition, results of operations and prospects.

Our computer and information technology systems, cloud-based computing services and those of our current and any future collaborators, service 

providers and other parties upon whom we rely are potentially vulnerable to malware, computer viruses, denial-of-service attacks (such as credential 
stuffing), ransomware attacks, user error or malfeasance, data corruption, cyber-based attacks, natural disasters, public health pandemics or epidemics 
(including, for example, the ongoing COVID-19 pandemic), terrorism, war and telecommunication and electrical failures that may result in damage to or 
the interruption or impairment of key business processes, or the loss or corruption of our information, including intellectual property, proprietary business 
information and personal information. We may also experience server malfunction, software or hardware failures, supply-chain cyber-attacks, loss of data 
or other computer assets and other similar issues. We have recently experienced security breaches of our information technology systems, such as through 
business email compromises. The techniques used to sabotage or to obtain unauthorized access to information systems, and networks in which cyber threat 
actors store data or through which they transmit data change frequently and we may be unable to implement adequate preventative measures. Any 
significant system failure, accident or security breach could have a material adverse effect on our business, financial condition and operations.

We may be required to expend significant resources (including financial), fundamentally change our business activities and practices, or modify our 

operations, including our clinical trial activities, or information technology in an effort to protect against security breaches and to mitigate, detect, and 
remediate actual and potential vulnerabilities. Relevant laws, regulations, industry standards and contractual obligations, may require us to implement 
specific security measures or use industry-standard or reasonable measures to protect against security breaches. The costs to us to mitigate network security 
problems, bugs, viruses, worms, malicious software programs and security vulnerabilities could be significant, and while we have implemented security 
measures to protect our data security and information technology systems, our efforts to address 

113

 
 
these problems may not be successful, and these problems could result in unexpected interruptions, data loss or corruption, delays, cessation of service and 
other harm to our business and our competitive position. If the information technology systems of our third-party vendors become subject to disruptions or 
security breaches, we may have insufficient recourse against such third parties and we may have to expend significant resources to mitigate the impact of 
such an event, and to develop and implement protections to prevent future events of this nature from occurring. Although we maintain cybersecurity 
insurance coverage, such insurance may not be adequate to cover all liabilities that we may incur. Furthermore, if a security breach were to occur and cause 
interruptions in our operations, it could result in a disruption of our development programs and our business operations, whether due to a loss of our trade 
secrets or other proprietary information or other similar disruptions.

For example, we, our third-party vendors, and our partners' third-party vendors have experienced social engineering efforts (including phishing 

attacks) designed to gain unauthorized access to our systems and information, including recent business email and system compromises. Similarly, we and 
our partners' third-party vendors may be a target of other phishing attacks, social engineering attacks and other cyber-attacks in the future. If a data security 
breach affects our or third parties’ systems upon which we rely, corrupts our data or results in the unauthorized disclosure or release of personally 
identifiable information, our reputation could be materially damaged or our operations disrupted. In addition, such a breach may require notification to 
governmental agencies, supervisory bodies, credit reporting agencies, the media, individuals, collaborators or others pursuant to various federal, state and 
foreign data protection, privacy and security laws, regulations and guidelines, industry standards, our policies and our contracts, if applicable. Such laws 
may include HIPAA and the Health Information Technology for Economic and Clinical Health Act, or HITECH. Under these laws specifically, notice of 
certain security breaches must be made to affected individuals, the Secretary of the Department of HHS, and, for extensive breaches, to the media or state 
attorneys general. Such a notice could further harm our reputation and our ability to compete. Such disclosures are costly, and the disclosure or the failure 
to comply with such requirements could lead to a material adverse effect on our reputation, business, or financial condition. Furthermore, a data security 
breach could result in fines, increased costs or loss of revenue and we could incur liability (such as through regulatory fines and penalties as well as private 
claims), our competitive position could be harmed and the further development and commercialization of our product candidates could be delayed. 
Additionally, federal, state and foreign laws and regulations can expose us to enforcement actions and investigations by regulatory authorities, and 
potentially result in regulatory penalties and significant legal liability, if our information technology security efforts fail.  

We receive, process, store and use personal information and other data, which subjects us to governmental regulation and other legal obligations, 
liability and risks related to privacy, security, and data protection, and our actual or perceived failure to comply with such obligations could lead to 
government enforcement actions (that could include fines and penalties), a disruption of our clinical trials or commercialization of our products, 
private litigation, harm to our reputation, or other adverse effects on our business or prospects.

We receive, process, store and use personal information and other data about our clinical trial participants, employees, collaborators and others. We 

are, or may become, subject to numerous domestic and foreign laws and regulations regarding privacy, data protection, and data security, industry 
standards, as well as policies, contracts and other obligations that apply to the processing of personal information by us and on our behalf, the scope of 
which is changing, subject to differing applications and interpretations and may be inconsistent among countries, or conflict with other rules. We strive to 
comply with all applicable data protection requirements and obligations; however new laws, policies, codes of conduct and legal obligations may arise, 
continue to evolve, be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and conflict with one another. Any failure or 
perceived failure by us or third parties working on our behalf to comply with applicable data protection requirements may result in governmental 
enforcement actions (including fines, penalties, judgments, settlements, additional reporting requirements and/or oversight, temporary or permanent bans 
on all or some processing of personal information, orders to destroy or not use personal information, imprisonment of company officials and public 
censure), civil claims, litigation, damage to our reputation and loss of goodwill, any of which could have a material adverse effect on our business, 
operations and financial performance, interrupt or stop clinical trials, limit our ability to develop or commercialize our products, or require us to revise or 
restructure our operations. With substantial uncertainty over the interpretation and application of these laws, regulations and other obligations, we may face 
challenges in addressing their requirements and making necessary changes to our policies and practices, and may incur significant costs and expenses in 
our efforts to do so. For additional information regarding these laws, see the section titled “Business—Government Regulation and Product Approval—
Privacy Laws.” 

Our employees, principal investigators, consultants and commercial partners may engage in misconduct or other improper activities, including 
noncompliance with regulatory standards and requirements and insider trading. 

114

 
 
 
We are exposed to the risk of fraud or other misconduct by our employees, principal investigators, consultants and commercial partners. Misconduct 

by these parties could include intentional failures, reckless and/or negligent conduct or unauthorized activities that violates (i) the laws and regulations of 
FDA and other regulatory authorities, including those laws requiring the reporting of true, complete and accurate information to such authorities, (ii) 
manufacturing standards, (iii) federal and state data privacy, security, fraud and abuse and other healthcare laws and regulations in the U.S. and abroad, (iii) 
laws that require the true, complete and accurate reporting of financial information or data and (iv) insider trading laws that restrict the buying and selling 
of shares of our common stock while in possession of material non-public information. In particular, sales, marketing and business arrangements in the 
healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. 
These laws and regulations restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive 
programs and other business arrangements. Such misconduct also could involve the improper use of individually identifiable information, including, 
without limitation, information obtained in the course of clinical trials, creating fraudulent data in our preclinical studies or clinical trials or illegal 
misappropriation of drug product, which could result in regulatory sanctions and cause serious harm to our reputation. In addition, during the course of our 
operations, our directors, executives and employees may have access to material non-public information regarding our business, our results of operations or 
potential transactions we are considering. We may not be able to prevent a director, executive or employee from violating our insider trading policies and 
buying or selling, or “tipping” others who might buy or sell, shares of our common stock on the basis of, or while having access to, material non-public 
information. If a director, executive or employee was to be investigated, or an enforcement action was to be brought against a director, executive or 
employee for insider trading, it could have a negative impact on our reputation and our stock price

It is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this 

activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from government investigations or other actions or 
lawsuits stemming from a failure to comply with these laws or regulations. Additionally, we are subject to the risk that a person or government could allege 
such fraud or other misconduct, even if none occurred. If any such actions are instituted against us and we are not successful in defending ourselves or 
asserting our rights, those actions could result in significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, 
exclusion from participating in government-funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight 
if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of noncompliance with these laws, contractual damages, 
reputational harm and the curtailment or restructuring of our operations, any of which could have a negative impact on our business, financial condition, 
results of operations and prospects. 

Our ability to use our net operating losses, or NOLs, to offset future taxable income may be subject to certain limitations. 

Although we recorded net income for the year ended December 31, 2021, we have otherwise incurred accumulated net losses since inception and 
have no assurances that we will continue to be profitable in the near future. As of December 31, 2021, we had net operating loss carryforwards of $24.2 
million for federal tax purposes and $126.6 million for state tax purposes. If not utilized, federal carryforwards will begin expiring in 2035 and state 
carryforwards will begin expiring in 2031. Our ability to use our federal and state net operating losses to offset potential future taxable income is dependent 
upon our generation of future taxable income before any expiration dates of the net operating losses, and we cannot predict with certainty when, or whether, 
we will generate sufficient taxable income to use all of our net operating losses.

In general, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, or the Code, a corporation that undergoes an “ownership 
change” (generally defined as a greater than 50 percentage point change (by value) in its equity ownership by certain stockholders over a rolling three-year 
period) is subject to limitations on its ability to utilize its pre-change NOLs to offset future taxable income. We may have experienced ownership changes 
in the past or as a result of the IPO and may experience ownership changes as a result of future offerings and/or subsequent changes in our stock ownership 
(some of which shifts are outside our control). In addition, Agenovir has experienced at least one ownership change in the past resulting in a limitation 
under Section 382 of the Code, which has been accounted for in calculating our available NOL carryforwards. As a result, if, and to the extent that we earn 
net taxable income, our ability to use our pre-change NOLs to offset such taxable income may be subject to limitations. 

The Tax Cuts and Jobs Act of 2017 and the CARES Act include, among other things, changes to U.S. federal tax rates and the rules governing NOL 

carryforwards. For example, NOLs arising in tax years ending after December 31, 2017 can be carried forward indefinitely, but the deductibility of such 
federal NOLs may be limited to 80% of current year taxable income for tax years beginning on or after January 1, 2021. Deferred tax assets for NOLs will 
need to be measured at the applicable 

115

 
 
tax rate in effect when the NOL is expected to be utilized. The changes in the carryforward periods, as well as the new limitation on use of NOLs may 
impact our ability to utilize our NOLs to offset taxable income in the future.

Risks Related to Ownership of Our Common Stock 

Our financial condition and results of operations may fluctuate from quarter to quarter and year to year, which makes them difficult to predict. 

We expect our financial condition and results of operations to fluctuate from quarter to quarter and year to year due to a variety of factors, many of 

which are beyond our control. Accordingly, you should not rely upon the results of any quarterly or annual periods as indications of future operating 
performance. In addition, we are exposed to market risks related to our investments, including changes in fair value of equity securities we hold which may 
fluctuate from quarter to quarter and year to year, which is discussed in greater detail under Item 7A. Quantitative and Qualitative Disclosures About 
Market Risk.

The market price of our common stock has been, and in the future, may be, volatile and fluctuate substantially, which could result in substantial losses 
for purchasers of our common stock. 

Our stock price has been, and in the future, may be, subject to substantial volatility. From October 11, 2019, our first day of trading on The Nasdaq 

Global Select Market, or Nasdaq, through February 22, 2022, the closing price of our stock ranged from $11.83 per share to $83.07 per share. As a result of 
the volatility in our stock price, our stockholders could incur substantial losses.

The stock market in general and the market for biopharmaceutical and pharmaceutical companies in particular, has experienced extreme volatility 

that has often been unrelated to the operating performance of particular companies. The ongoing COVID-19 pandemic, for example, has negatively 
affected some sectors of the stock market and investor sentiment and has resulted in significant volatility. As a result of this volatility, you may not be able 
to sell your common stock at or above the price you paid for your shares. Market and industry factors may cause the market price and demand for our 
common stock to fluctuate substantially, regardless of our actual operating performance, which may limit or prevent investors from selling their shares at or 
above the price paid for the shares and may otherwise negatively affect the liquidity of our common stock. 

In addition, public statements by us, government agencies, our competitors, the media or others relating to the ongoing COVID-19 pandemic 

(including regarding our and others’ efforts to develop COVID-19 therapies) and the impact of such statements on investors’ general perception of our 
company and our business have in the past resulted, and may in the future result, in significant fluctuations in our stock price. Given the global focus on the 
COVID-19 pandemic, information in the public arena on this topic, whether or not accurate, has had and will likely continue to have an outsized impact 
(positive or negative) on our stock price. Moreover, sales of a substantial number of shares of our common stock by our stockholders in the public market 
or the perception that these sales might occur, have in the past, and may in the future depress the market price of our common stock. Information related to 
our development, manufacturing, regulatory and commercialization efforts with respect to sotrovimab and VIR-7832, or information regarding such efforts 
by competitors with respect to their potential therapies, may meaningfully impact our stock price.

Some companies that have experienced volatility in the trading price of their shares have been the subject of securities class action litigation. Any 

lawsuit to which we are a party, with or without merit, may result in an unfavorable judgment. We also may decide to settle lawsuits on unfavorable terms. 
Any such negative outcome could result in payments of substantial damages or fines, damage to our reputation or adverse changes to our business 
practices. Defending against litigation is costly and time-consuming and could divert our management’s attention and our resources. Furthermore, during 
the course of litigation, there could be negative public announcements of the results of hearings, motions or other interim proceedings or developments, 
which could have a negative effect on the market price of our common stock. 

Concentration of ownership of our common stock among our existing executive officers, directors and principal stockholders may prevent new 
investors from influencing significant corporate decisions. 

Our executive officers, directors and stockholders who own more than 5% of our outstanding common stock beneficially own a significant 
percentage of our outstanding common stock. If these persons acted together, they may be able to significantly influence all matters requiring stockholder 
approval, including the election and removal of directors and approval of any merger, consolidation or sale of all or substantially all of our assets. The 
concentration of voting power and 

116

 
 
 
 
 
transfer restrictions could delay or prevent an acquisition of our company on terms that other stockholders may desire or result in the management of our 
company in ways with which other stockholders disagree. 

If research analysts do not publish research or reports, or publish unfavorable research or reports, about us, our business or our market, our stock 
price and trading volume could decline. 

The trading market for our common stock will be influenced by the research and reports that industry or financial analysts publish about us or our 

business. If any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model, our intellectual property or our stock 
performance, or if the clinical trials and operating results fail to meet the expectations of analysts, our stock could decline. If analysts cease coverage of us 
or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to 
decline.

Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be your sole 
source of gain. 

You should not rely on an investment in our common stock to provide dividend income. We have never declared or paid cash dividends on our 

capital stock. We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business. In addition, the terms 
of any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be your sole 
source of gain in the foreseeable future. 

We have incurred and we will continue incur significant increased costs as a result of operating as a public company, and our management will be 
required to devote substantial time to new compliance initiatives. 

As a public company, we have incurred and we will continue to incur significant legal, accounting, investor relations and other expenses. In 
addition, the Sarbanes-Oxley Act and rules subsequently implemented by the Securities and Exchange Commission, or SEC, and Nasdaq have imposed 
various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate 
governance practices. Further, in July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act was enacted, pursuant to which the SEC 
adopted rules and regulations related to corporate governance and executive compensation, such as “say on pay” and proxy access. Emerging growth 
companies are permitted to implement many of these requirements over time, however, we are no longer an emerging growth company as of December 31, 
2020, and expect to incur additional compliance-related expenses as a result.

Stockholder activism, the current political environment and the current high level of U.S. government intervention and regulatory reform may also 
lead to substantial new regulations and disclosure obligations, which may in turn lead to additional compliance costs and impact the manner in which we 
operate our business in ways we do not currently anticipate. Our management and other personnel will need to devote a substantial amount of time to 
comply with these requirements. Moreover, these requirements will increase our legal and financial compliance costs and will make some activities more 
time-consuming and costly. For example, we expect that these rules and regulations may make it more difficult and more expensive for us to obtain director 
and officer liability insurance. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements. 

As a public company, we may also be subject to more stringent state law requirements, such as California Senator Bill 826, which generally requires 
public companies with principal executive offices in California to have a minimum number of females on the company’s board of directors, and California 
Assembly Bill 979, which generally requires public companies with principal executive offices in California to include specified numbers of directors from 
“underrepresented communities.” We are currently compliant with the requirements, but there are no assurances that we will be compliant in the future. If 
we fail to comply with either Senator Bill 826 or Assembly Bill 979, we could be fined by the California Secretary of State, with a $100,000 fine for the 
first violation and a $300,000 for each subsequent violation, and our reputation may be adversely affected. 

If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate and timely financial statements 
could be impaired, investors may lose confidence in our financial reporting and the trading price of our common stock may decline. 

Pursuant to Section 404 of the Sarbanes-Oxley Act, or Section 404, we are required to furnish a report by our management on our internal control 

over financial reporting, including an attestation report on internal control over financial 

117

 
 
 
 
 
reporting issued by our independent registered public accounting firm. We were previously not required to include an attestation report on internal control 
over financial reporting issued by our independent registered public accounting while we were an emerging growth company. However, we are no longer 
an emerging growth company as of December 31, 2020. The rules governing the standards that must be met for management to assess our internal control 
over financial reporting are complex and require significant documentation, testing and possible remediation. To comply with the Sarbanes-Oxley Act, the 
requirements of being a reporting company under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and any complex accounting 
rules in the future, we may need to upgrade our information technology systems; implement additional financial and management controls, reporting 
systems and procedures; and hire additional accounting and finance staff. We are currently in the process of hiring additional accounting and finance staff 
as we grow our business. If we are unable to hire the additional accounting and finance staff necessary to comply with these requirements, we may need to 
retain additional outside consultants. If we or, if required, our auditors, are unable to conclude that our internal control over financial reporting is effective, 
investors may lose confidence in our financial reporting and the trading price of our common stock may decline. 

We cannot assure you that there will not be material weaknesses in our internal control over financial reporting in the future. Our previous 
acquisitions and strategic transactions and resulting international operations have increased the complexity of our accounting, and additional acquisitions 
and transactions and further geographic expansion will likely increase this complexity and the related accounting challenges. Any failure to maintain 
internal control over financial reporting could severely inhibit our ability to accurately report our financial condition, results of operations or cash flows. If 
we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines 
that we have a material weakness in our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our 
financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by Nasdaq, the SEC or other 
regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective 
control systems required of public companies, could also restrict our future access to the capital markets. 

Our reported financial results may be adversely affected by changes in accounting principles generally accepted in the United States. 

Generally accepted accounting principles in the United States are subject to interpretation by the Financial Accounting Standards Board, or FASB, 
or the SEC, and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could 
have a significant effect on our reported financial results, may retroactively affect previously reported results, could cause unexpected financial reporting 
fluctuations and may require us to make costly changes to our operational processes and accounting systems. 

Provisions in our corporate charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, 
more difficult and may prevent attempts by our stockholders to replace or remove our current management. 

Provisions in our corporate charter and our bylaws may discourage, delay or prevent a merger, acquisition or other change in control of us that 
stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions also could 
limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common 
stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may frustrate or 
prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of 
our board of directors. For a summary of these provisions, see the section titled “Anti-Takeover Provisions of Delaware Law and Our Amended and 
Restated Certificate of Incorporation and Amended and Restated Bylaws—Amended and Restated Certificate of Incorporation and Amended and Restated 
Bylaws” in Exhibit 4.3 Description of Capital Stock filed as part of this Annual Report on Form 10-K.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for 
substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes 
with us or our directors, officers or employees. 

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware (or, if and only if the Court of 

Chancery of the State of Delaware lacks subject matter jurisdiction, any state court located within the State of Delaware or, if and only if all such state 
courts lack subject matter jurisdiction, the federal district court for the 

118

 
 
 
 
District of Delaware) will be the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: 

•

•

•

•

•

any derivative action or proceeding brought on our behalf;

 any action or proceeding asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers or other 
employees to us or our stockholders;

any action or proceeding asserting a claim against us or any of our current or former directors, officers or other employees, arising out of or 
pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws;

any action or proceeding to interpret, apply, enforce or determine the validity of our certificate of incorporation or our bylaws; and

any action asserting a claim against us or any of our directors, officers or other employees governed by the internal affairs doctrine.

This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim for which the U.S. 
federal courts have exclusive jurisdiction. Furthermore, Section 22 of the Securities Act of 1933, as amended, or the Securities Act, creates concurrent 
jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such 
claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other 
considerations, our amended and restated certificate of incorporation further provides that the federal district courts of the United States will be the 
exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act of 1933, unless we consent in writing to the 
selection of an alternative forum. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may 
nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, we would expect to 
vigorously assert the validity and enforceability of the exclusive forum provisions of our amended and restated certificate of incorporation. This may 
require significant additional costs associated with resolving such action in other jurisdictions and there can be no assurance that the provisions will be 
enforced by a court in those other jurisdictions.

These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or 

our directors, officers or other employees, which may discourage these types of lawsuits. Furthermore, the enforceability of similar choice of forum 
provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of 
provisions to be inapplicable or unenforceable. If a court were to find the exclusive-forum provision contained in our amended and restated certificate of 
incorporation to be inapplicable or unenforceable in an action, we may incur further significant additional costs associated with resolving such action in 
other jurisdictions, all of which could harm our business.

Item 2. Properties. 

Our corporate headquarters are located in San Francisco, California, where we lease approximately 183,027 square feet of office, research and 

development, engineering, and laboratory space pursuant to three lease agreements that expire at various dates through 2033, two of which are renewable 
for additional one and five years, respectively. 

We also have several other locations, including St. Louis, Missouri, where we lease approximately 60,649 square feet of office, research and 

development, and laboratory space pursuant to two lease agreements that expire at various dates through 2028; Portland, Oregon, where we lease 
approximately 10,559 square feet of office, research and development, engineering, and laboratory space pursuant to two lease agreements that expire at 
various dates through 2027, one of which is renewable for an additional five years; and Bellinzona, Switzerland, where we lease approximately 12,500 
square feet of office, research and development, engineering, and laboratory space pursuant to a lease agreement which expires on December 31, 2028, 
with an option to extend for five years. 

We believe that our existing facilities are adequate for our near-term needs, but expect to need additional space as we grow, and we believe that 

suitable additional alternative spaces will be available in the future on commercially reasonable terms, if required. 

Item 3. Legal Proceedings. 

From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. We are not currently party to any 
material legal proceedings, and we are not aware of any pending or threatened legal proceeding against us that we believe could have an adverse effect on 
our business, operating results or financial condition. 

Item 4. Mine Safety Disclosures.

Securities Authorized for Issuance Under Equity Compensation Plans

The information required by this Item regarding equity compensation plans is incorporated by reference to the information set forth in PART III 

Item 12 of this Annual Report on Form 10-K.

Use of Proceeds from Registered Securities

On October 10, 2019, we completed our initial public offering, or IPO, and issued 7,142,858 shares of our common stock at an initial offering price 
of $20.00 per share. We received net proceeds from the IPO of approximately $126.4 million, after deducting underwriting discounts and commissions of 
approximately $10.0 million and expenses of approximately $6.4 million. None of the expenses associated with the IPO were paid to directors, officers, 
persons owning 10% or more of any class of equity securities, or to their associates, or to our affiliates. Goldman Sachs & Co. LLC, J.P. Morgan Securities 
LLC, Cowen and Company, LLC and Barclays Capital Inc. acted as book-running managers for the IPO.

Shares of our common stock began trading on The Nasdaq Global Select Market on October 11, 2019. The offer and sale of the shares were 
registered under the Securities Act on Registration Statement on Form S-1 (Registration No. 333-233604), which was declared effective on October 10, 
2019.

There has been no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC on October 

11, 2019, pursuant to Rule 424(b)(4). As of December 31, 2021, we have used all of the net offering proceeds from the IPO.

Overview 

We are a commercial-stage immunology company focused on combining immunologic insights with cutting-edge technologies to treat and prevent 

serious infectious diseases. Infectious diseases are among the leading causes of death worldwide and can cause trillions of dollars of direct and indirect 
economic burden each year – as evidenced by the coronavirus disease 2019, or COVID-19, pandemic. We believe that now is the time to apply the recent 
and remarkable advances in immunology to combat current and prepare for future infectious diseases. Our approach begins with identifying the limitations 
of the immune system in combating a particular pathogen, the vulnerabilities of that pathogen and the reasons why previous approaches have failed. We 
then bring to bear powerful technologies that we believe, individually or in combination, will lead to effective therapies. 

Our current pipeline consists of sotrovimab (previously VIR-7831; and where marketing authorization has been granted, marketed under the brand 
name Xevudy®) and other product candidates targeting COVID-19, hepatitis B virus, or HBV, influenza A virus, and human immunodeficiency virus, or 
HIV. We have assembled four technology platforms, focused on antibodies, T cells, innate immunity and small interfering ribonucleic acid, or siRNA, 
through internal development, collaborations and acquisitions. We have built an industry-leading team that has deep experience in immunology, infectious 
diseases, and product development and commercialization. Given the global impact of infectious diseases, we are committed to developing cost-effective 
treatments that can be delivered at scale. 

COVID-19

Sotrovimab is an investigational severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2, neutralizing monoclonal antibody, or mAb, that 

incorporates Xencor, Inc.'s, or Xencor, Xtend™ technology.

•

•

In May 2021, the U.S. Food and Drug Administration, or FDA, granted an Emergency Use Authorization, or EUA, to sotrovimab for the 
early treatment of mild to moderate COVID-19 in adults and pediatric patients (12 years of age and older weighing at least 40 kg) with 
positive results of direct SARS-CoV-2 viral testing, and at high risk for progression to severe COVID-19, including hospitalization or death. 
We also received a positive scientific opinion from the Committee for Human Medicinal Products in the European Union, or EU, for 
sotrovimab in May 2021. In June 2021, we announced confirmatory full results for the Phase 3 COVID-19 Monoclonal antibody Efficacy 
Trial - Intent to Care Early, or COMET-ICE, trial, which resulted in an adjusted relative risk reduction of 79% (p<0.001) in all-cause 
hospitalization for more than 24 hours or death due to any cause by Day 29 compared to placebo, meeting the primary endpoint of the trial. 
In December 2021, the European Commission granted marketing authorization to Xevudy® (sotrovimab) in the EU for the treatment of 
adults and adolescents at increased risk of progressing to severe COVID-19.

We have made significant progress increasing global patient access to sotrovimab in collaboration with Glaxo Wellcome UK Limited and 
GlaxoSmithKline Biologicals S.A. (individually and collectively referred to as GSK). Sotrovimab has been granted EUA, temporary 
authorization or marketing approval (under the brand name Xevudy®) in more than 40 countries.

123

 
•

To date, binding agreements have been received for the sale of approximately 1.7 million doses of sotrovimab worldwide. 

o

o

In November 2021, we and GSK announced the sale of more than 750,000 doses globally to date, including multiple contracts with 
the U.S. government. Approximately 90% of those doses were delivered in 2021 and the remainder are expected to be delivered 
throughout the first half of 2022. The delivered doses led to the recognition of $917.2 million of sotrovimab collaboration revenue in 
2021.

In January 2022, we and GSK announced the sale of an additional 600,000 doses to the U.S. government, which are expected to be 
delivered throughout the first quarter of 2022, and the sale of approximately 350,000 additional doses to other countries, which are 
expected to be delivered throughout the first half of 2022. Based solely on the binding agreements received to date, we expect to 
recognize approximately $1.1 billion of sotrovimab collaboration revenues when the doses are delivered in the first half of 2022.

We and GSK expect to manufacture approximately two million doses of sotrovimab in the first half of 2022, and additional doses in the 
second half of 2022. 

During and following the fourth quarter, we announced preclinical data generated through pseudovirus testing demonstrating that sotrovimab 
retains neutralizing activity against the highly divergent Omicron variant (B.1.1.529). 

In  February  2022,  we  published  pseudovirus  data  demonstrating  a  16-fold  shift  in  neutralization  activity  against  the  Omicron  BA.2 
subvariant. Our BA.2 results were derived from 10 independent experiments that were conducted using an optimized pseudovirus assay. This 
is  the  same  assay  that  was  used  to  generate  data  for  previous  variants.  These  data  have  been  shared  with  regulatory  agencies  around  the 
world. Initial feedback from the FDA question our conclusion that the 500 mg intravenous, or IV, dose of sotrovimab retains activity against 
the BA.2 Omicron subvariant based on our current modeling assumptions, and the FDA has asked for additional data to support our position. 
The FDA also requested safety data for higher doses. Both have been provided to the FDA and we are awaiting further correspondence.

The  Health  Care  Provider  Fact  Sheet  was  recently  updated  to  show  that  sotrovimab’s  neutralization  activity  was  reduced  an  average  fold 
change in EC50 value of 16-fold against the SARS-CoV-2 Omicron B.1.1.529/BA.2 spike variant compared to wild-type. The Fact Sheet also 
noted that the clinical relevance of the 16-fold reduction in sotrovimab activity against the SARS-CoV-2 Omicron B.1.1.529/BA.2 variant is 
unknown. 

As of February 28, 2022, the FDA noted on its EUA website that sotrovimab is currently authorized in all U.S. regions until further notice by 
the FDA.

In November 2021, we announced the results of the Phase 3, randomized, open-label COMET-Treatment of Acute COVID-19 with 
Intramuscular monocLonal antibody, or COMET-TAIL trial, which achieved its primary endpoint, demonstrating that 500 mg intramuscular, 
or IM, administration of sotrovimab (n=376) was non-inferior to 500 mg IV administration (n=378) for the early treatment of mild to 
moderate COVID-19 in high-risk, non-hospitalized adults and adolescents. Low rates of serious adverse events (≤1% in both arms) were 
observed. Based on the results of the COMET-TAIL trial, in January 2022, we and GSK submitted an application to the FDA requesting an 
amendment to the EUA for sotrovimab to include IM administration. 

We and GSK plan to submit a Biologics License Application, or BLA, for sotrovimab to the FDA in the second half of 2022.

We and GSK are collaborating to assess the use of sotrovimab in uninfected immunocompromised patients to determine whether sotrovimab 
can prevent symptomatic COVID-19 infection. Two Phase 3 trials are expected to start in the second quarter of 2022. One is a platform trial 
and  one  is  a  company  sponsored  trial,  COVID-19  Monoclonal  antibody  Efficacy  Trial  –  Stop  Transmission  of  Acute  SARS-COV-2,  or 
COMET-STAR. The primary endpoint for both trials is incidence of symptomatic PCR-confirmed COVID-19. The analysis of the primary 
endpoint of COMET-STAR will be event driven, and could be as early as the second half of 2022.

Sotrovimab is also being evaluated among patients hospitalized with COVID-19 in the U.K. as part of the Randomized Evaluation of 
COVID-19 Therapy, or RECOVERY, trial. Initial data are expected in the second half of 2022.

VIR-7832 is an investigational vaccinal SARS-CoV-2-neutralizing mAb that incorporates Xencor’s Xtend and other Fc technologies. VIR-7832 
shares the same characteristics as sotrovimab and has been engineered to potentially be a therapeutic T cell vaccine to further help treat and/or prevent 
COVID-19. The U.K.'s National Health Service-supported AGILE

initiative evaluating VIR-7832 in a Phase 1b/2a trial of adults with mild to moderate COVID-19 remains ongoing. To date, no safety signals have been 
reported for the 50 mg, 150 mg and 500 mg dose cohorts. The first patient in the Phase 2a portion of the trial was dosed in February 2022. Additional data 
are expected in the first half of 2022. 

HBV

VIR-2218 is an investigational HBV-targeting siRNA. 

•

•

•

In June 2021, we announced clinical data from our Phase 2 trial of VIR-2218 alone and in combination with pegylated interferon alpha, or 
PEG-IFN-α. First, with VIR-2218 as monotherapy, the trial demonstrated a strong safety profile and a substantial, durable and dose 
dependent reduction of hepatitis B virus surface antigen, or HBsAg, through 48 weeks. Second, evaluating VIR-2218 alone and in 
combination with PEG-IFN-α for 12 weeks, more rapid and substantial declines in HBsAg compared to VIR-2218 alone were observed. 

In November 2021, we announced additional data evaluating VIR-2218 in combination with PEG-IFN-α for 24 weeks. New findings 
demonstrated that concurrent initiation of VIR-2218 and PEG-IFN-α therapy resulted in earlier and more substantial HBsAg reductions 
compared to VIR-2218 alone or with PEG-IFN-α following a VIR-2218 lead-in. Also, three participants achieved HBsAg loss below the 
lower limit of quantification by Week 24; two of three achieved anti-HBs seroconversion. Additional data are expected in the first half of 
2022. 

VIR-2218 is also being evaluated in additional clinical trials with collaborators.

VIR-3434 is an investigational HBV-neutralizing mAb that incorporates Xencor’s Xtend and other Fc technologies. 

•

•

In July 2021, we initiated the Phase 2 Monoclonal Antibody siRNA Combination against Hepatitis B, or MARCH, trial to evaluate the 
combination of VIR-2218 and VIR-3434 as a functional cure regimen for chronic HBV infection. Initial data are expected in the first half of 
2022. As some of our clinical trial sites are in Ukraine and Moldova, we are monitoring the situation to determine any impact resulting from 
the current conflict in this region.

In November 2021, we announced that a single dose of six mg, 18 mg, or 75 mg of VIR-3434 resulted in rapid HBsAg reductions in most 
participants within approximately one week post-dose, and the largest and most sustained reductions in HBsAg were observed in the 75 mg 
cohort. Initial data are expected in the first half of 2022. 

Influenza A virus

VIR-2482 is an investigational mAb designed for the prevention of influenza A that incorporates Xencor’s Xtend technology. In August 2019, we 

initiated dosing in the Phase 1/2 clinical trial for VIR-2482. VIR-2482 has been well-tolerated in the approximately 100 healthy volunteers dosed in Phase 
1. Anticipating an increase in the incidence of influenza in the Northern Hemisphere this coming winter, we expect to initiate a Phase 2 trial in the second 
half of 2022.

Additionally, we and GSK are evaluating the potential of several next-generation mAbs for influenza treatment and prevention, functional genomics 

applications for respiratory targets, and mAbs for non-influenza diseases under the collaboration agreement with GSK executed in May 2021, or the 2021 
GSK Agreement. For details regarding the 2021 GSK Agreement, see Note 7—Collaboration and License Agreements to our consolidated financial 
statements included elsewhere in this Annual Report on Form 10-K. 

HIV

VIR-1111 is an investigational HIV T cell vaccine based on human cytomegalovirus, or HCMV. In December 2020, we initiated a Phase 1 trial of 

VIR-1111. No safety signals have been reported to date and we expect to have additional clinical data in the first half of 2022. 

In January 2022, we announced an expansion of our collaboration with the Bill & Melinda Gates Foundation to include the advancement of 
innovative platform technologies in the development of broadly neutralizing antibodies designed to provide a “vaccinal effect” aimed at a functional cure 
of HIV and the prevention of malaria.

Financial Overview

We were incorporated in April 2016 and commenced principal operations later that year. To date, we have focused primarily on organizing and 

staffing our company, business planning, raising capital, identifying, acquiring, developing and in-licensing our technology platforms and product 
candidates, and conducting preclinical studies and clinical trials. 

We have financed our operations primarily through sales of our common stock from our initial public offering, subsequent follow-on offering and 

convertible preferred securities, and payments received under our grant and collaboration agreements. As of December 31, 2021, excluding restricted cash, 
we had $909.5 million in cash, cash equivalents and investments, and after excluding the equity investment in Brii Biosciences Limited, or Brii Bio Parent, 
we had $766.4 million. Based upon our current operating plan, we believe that $766.4 million as of December 31, 2021 will enable us to fund our 
operations for at least the next 12 months. However, our operating plan may change as a result of many factors currently unknown to us, and we may need 
to seek additional financing to fund our long-term operations sooner than planned. See the section titled “Liquidity, Capital Resources and Capital 
Requirements—Future Funding Requirements” below for additional information.    

Although we recorded net income for the year ended December 31, 2021, we have otherwise incurred accumulated net losses since inception and 

may continue to incur net losses in the foreseeable future. To date, sotrovimab has been granted EUA, temporary authorization or marketing approval 
(under the brand name, Xevudy®) in more than 40 countries. Although we (through our collaborator GSK) have recently entered into procurement 
agreements to supply sotrovimab to governments around the world and began to recognize revenue for sotrovimab, the extent of future revenue remains 
uncertain. We have not obtained regulatory approval for any other product candidates, and we do not expect to generate significant revenue from the sale of 
our other product candidates until we complete clinical development, submit regulatory filings and receive approvals from the applicable regulatory bodies 
for such product candidates, if ever. Our net income was $528.6 million for the year ended December 31, 2021. Our net losses were $298.7 million and 
$174.7 million for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2021, we had an accumulated deficit of $138.6 million. 
Our primary use of our capital resources is to fund our operating expenses, which consist primarily of expenditures related to identifying, acquiring, 
developing, manufacturing and in-licensing our technology platforms and product candidates, and conducting preclinical studies and clinical trials, and to a 
lesser extent, selling, general and administrative expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these 
expenses, as reflected in the change in our outstanding accounts payable and accrued expenses. Although we began recognizing revenue for sotrovimab and 
have substantial deferred revenue under our 2021 GSK Agreement, we may continue to incur net operating losses for at least the next several years as the 
extent of future revenue remains uncertain. In particular, we expect our expenses and losses to increase as we continue our research and development 
efforts, advance our product candidates through preclinical and clinical development, seek regulatory approval, prepare for commercialization, as well as 
hire additional personnel, protect our intellectual property and incur additional costs associated with being a public company. We also expect to increase the 
size of our administrative functions to support the growth of our business. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-
year, depending on the timing of our clinical trials and our expenditures on other research and development activities. 

We are currently manufacturing product candidates from three of our platforms: antibodies, T cells and siRNAs. We have established our own 
internal process development, manufacturing and quality capabilities and are working with contract development and manufacturing organizations, or 
CDMOs, to supply our early- and late-stage product candidates in the near term. We continue to expand our internal capabilities and resources in process 
development, analytical development, quality, manufacturing and supply chain, which are supported by our San Francisco, California, and Portland, 
Oregon facilities that include laboratories for process development, production of HCMV research viral seed stock and selected quality control testing for 
our product candidates. We have established relationships with multiple CDMOs and have produced material to support preclinical studies and Phase 1 
through Phase 3 clinical trials. Material for Phase 3 clinical trials and commercial supply will generally require large-volume, low-cost-of-goods 
production. For example, for our COVID-19 program, we and our collaborator GSK have executed manufacturing agreements with CDMOs having large-
scale capacity to support future scale-up and product supply, particularly for potential commercialization. 

COVID-19 Business Update

We have implemented a number of plans and policies designed to address and mitigate the impact of the ongoing COVID-19 pandemic on our 
employees and our business. We continue to closely monitor the COVID-19 situation and will evolve our plans and policies as needed going forward. As a 
result of these developments, in March 2020, we implemented work-from-home policies for most of our employees. We have also implemented plans, 
which continue to evolve based on the current climate and response to the ongoing COVID-19 pandemic, to reopen our offices to allow employees to 
return when appropriate. Although these plans are based on a phased approach consistent with local government requirements, and 

126

 
focused on employee safety, and contemplate returning to remote work should new restrictions be implemented, there is uncertainty regarding the recent 
phased reopening, which may be rolled back, and restrictions re-implemented. We are also working to provide our employees with the support they need to 
ensure continuity of business operations. We are working closely with our CDMOs to manage our supply chain activities and mitigate any potential 
disruptions to our clinical trial supplies as a result of the COVID-19 pandemic. However, there are no assurances that our manufacturing and supply chain 
infrastructure will remain uninterrupted and reliable, or that the CDMOs will be able to satisfy demand in a timely manner and not have supply chain 
disruptions due to COVID-19 related shutdowns, stock-outs due to raw material shortages and/or greater than anticipated demand or quality issues given 
the operational challenges and raw material shortages that have been experienced during the COVID-19 pandemic. For some of our clinical development 
programs, we are experiencing, and may continue to experience, a disruption or delay in our ability to initiate trial sites and enroll and assess patients. In 
addition, we rely on contract research organizations or other third parties to assist us with clinical trials, and we cannot guarantee that they will continue to 
perform their contractual duties in a timely and satisfactory manner as a result of the COVID-19 pandemic.  

Our Collaboration, License and Grant Agreements 

We have entered into collaboration, license and grant arrangements with various third parties. For details regarding these and other agreements, see 
the section titled “Business—Our Collaboration, License and Grant Agreements” and Note 6—Grant Agreements and Note 7—Collaboration and License 
Agreements to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. 

Our Acquisitions 

We have completed various acquisitions. For details regarding our acquisitions, see the section titled “Business—Our Acquisition Agreements” and 

Note 4—Acquisitions to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. 

Components of Operating Results 

Revenues 

To date, sotrovimab has been granted EUA, temporary authorization or marketing approval (under the brand name, Xevudy®) in more than 40 

countries. We (through our collaborator GSK) have recently entered into procurement agreements to supply sotrovimab to governments around the world, 
and we have begun recognizing revenue from our profit share under our definitive collaboration agreement with GSK executed in June 2020, or the 2020 
GSK Agreement. However, the extent of future revenue remains uncertain. We have not obtained regulatory approval for any other product candidates, and 
we do not expect to generate any significant revenue from the sale of our other product candidates until we complete clinical development, submit 
regulatory filings and receive approvals from the applicable regulatory bodies for such product candidates, if ever. 

Our revenues consist of the following: 

Collaboration revenue includes recognition of our profit share from the sales of sotrovimab pursuant to the 2020 GSK Agreement. Our contractual 

share of 72.5% from the sales of sotrovimab is applied to the revenue reported in the period by GSK, net of cost of goods sold and allowable expenses from 
both GSK and us (e.g., medical affairs, selling and marketing expenses) and adding back our expenses that appear elsewhere in the consolidated statement 
of operations (e.g., cost of revenue).  

Contract revenue includes recognition of revenue generated from license rights issued to GSK, from research and development services under other 

third-party contracts, and from a clinical supply agreement with Brii Biosciences Offshore Limited, or Brii Bio.

Grant revenue is comprised of revenue derived from grant agreements with government-sponsored and private organizations. 

License revenue from a related party is comprised of revenue related to Brii Bio’s exercise of its option to obtain exclusive rights to develop and 

commercialize compounds arising from VIR-2218 in greater China recognized in the prior year.  

127

 
Operating Expenses

Cost of Revenue

Cost of revenue currently represents royalties earned by third-party licensors on net sales of sotrovimab by us or our collaborators. We recognize 

these royalties as cost of revenue when we recognize the corresponding revenue that gives rise to payments due to our licensors.

Research and Development 

To date, our research and development expenses have related primarily to discovery efforts and preclinical and clinical development of our product 

candidates. Research and development expenses are recognized as incurred and payments made prior to the receipt of goods or services to be used in 
research and development are capitalized until the goods or services are received. We do not track research and development expenses by product 
candidate. 

Research and development expenses consist primarily of costs incurred for our product candidates in development and prior to regulatory approval, 

which include: 

•

•

•

•

•

expenses related to license and collaboration agreements, and change in fair value of certain contingent consideration obligations arising 
from business acquisitions; 

personnel-related expenses, including salaries, benefits and stock-based compensation for personnel contributing to research and 
development activities; 

expenses incurred under agreements with third-party contract manufacturing organizations, contract research organizations, and consultants; 

clinical costs, including laboratory supplies and costs related to compliance with regulatory requirements; and 

other allocated expenses, including expenses for rent and facilities maintenance, and depreciation and amortization. 

We expect our research and development expenses to increase substantially in absolute dollars for the foreseeable future as we advance our product 
candidates into and through preclinical studies and clinical trials and pursue regulatory approval of our product candidates. The process of conducting the 
necessary clinical research to obtain regulatory approval is costly and time-consuming. The actual probability of success for our product candidates may be 
affected by a variety of factors including: the safety and efficacy of our product candidates, early clinical data, investment in our clinical programs, the 
ability of collaborators to successfully develop our licensed product candidates, competition, manufacturing capability and commercial viability. To date, 
sotrovimab has been granted EUA, temporary authorization or marketing approval (under the brand name, Xevudy®) in more than 40 countries. However, 
we may never succeed in achieving BLA or other similar approvals for sotrovimab or any of our product candidates. In addition, COVID-19 treatment 
standards are susceptible to rapid changes in epidemiology and the emergence of new variants, thus, sotrovimab may be rendered inferior or obsolete in the 
future. As a result of the uncertainties discussed above, we are unable to determine the duration and completion costs of our research and development 
projects or when and to what extent we will generate significant revenue from the commercialization and sale of sotrovimab or any of our product 
candidates. Clinical and preclinical development timelines, the probability of success and development costs can differ materially from expectations. We 
anticipate that we will make determinations as to which product candidates to pursue and how much funding to direct to each product candidate on an 
ongoing basis in response to the results of ongoing and future preclinical studies and clinical trials, regulatory developments, our ongoing assessments as to 
each product candidate’s commercial potential and the impact of public health epidemics, such as the COVID-19 pandemic. In addition, we cannot forecast 
which product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements 
would affect our development plans and capital requirements. 

Our clinical development costs may vary significantly based on factors such as: 

•

•

•

•

whether a collaborator is paying for some or all of the costs; 

per patient trial costs; 

the number of trials required for approval; 

the number of sites included in the trials; 

128

 
•

•

•

•

•

•

•

•

•

•

the countries in which the trials are conducted; 

the length of time required to enroll eligible patients; 

the number of patients that participate in the trials; 

the number of doses that patients receive; 

the drop-out or discontinuation rates of patients; 

potential additional safety monitoring requested by regulatory agencies; 

the duration of patient participation in the trials and follow-up; 

the cost and timing of manufacturing our product candidates; 

the phase of development of our product candidates; and 

the efficacy and safety profile of our product candidates. 

Selling, General and Administrative 

Our selling, general and administrative expenses consist primarily of personnel-related expenses for personnel in executive, finance and other 

administrative functions, facilities and other allocated expenses, other expenses for outside professional services, including legal, audit and accounting 
services, insurance costs and change in fair value of certain contingent consideration obligations arising from business acquisitions. Personnel-related 
expenses consist of salaries, benefits and stock-based compensation.  

We expect our selling, general and administrative expenses to increase substantially in absolute dollars in the foreseeable future as we continue to 

support our continued research and development activities, and commercialization activities for our EUA product or any of our product candidates, if 
approved, and to grow our business. We also anticipate incurring additional expenses associated with operating as a public company, including increased 
expenses related to audit, legal, regulatory, and tax-related services associated with maintaining compliance with the rules and regulations of the SEC and 
standards applicable to companies listed on a national securities exchange, additional insurance expenses, investor relations activities and other 
administrative and professional services. 

Change in Fair Value of Equity Investments 

Change in fair value of equity investments consists of the remeasurement of our investment in Brii Bio Parent's ordinary shares based on the quoted 

market price at each reporting date.

Interest Income 

Interest income consists of interest earned on our cash, cash equivalents and investments. 

Other Income (Expense), Net 

Other income (expense), net consists of gains and losses from foreign currency transactions and the remeasurement of contingent consideration 

related to our acquisition of TomegaVax, Inc., or TomegaVax. 

Provision for Income Taxes 

Provision for income taxes consisted primarily of income tax on our domestic and foreign operations.

The increase in collaboration revenue for the year ended December 31, 2021 compared to the same period in 2020 was due to our profit-sharing 

arrangement with GSK for the sale of sotrovimab under our 2020 GSK Agreement, for which there were no comparable revenues recognized in the prior 
year. Our contractual share of 72.5% from the sales of sotrovimab is applied to the revenue reported in the period by GSK, net of cost of goods sold and 
allowable expenses from both GSK and us (e.g., medical affairs, selling, and marketing expenses) and adding back our expenses that appear elsewhere in 
the consolidated statement of operations (e.g., cost of revenue). 

The increase in contract revenue for the year ended December 31, 2021 compared to the same period in 2020 was primarily due to $168.3 million 
related to the license granted to GSK upon execution of the 2021 GSK Agreement, partially offset by $43.3 million related to the license granted to GSK 
upon execution of our 2020 GSK Agreement in the prior year. 

The decrease in grant revenue for the year ended December 31, 2021 compared to the same period in 2020 was primarily due to a decrease of $3.4 
million recognized under the amended grant agreement, originally entered into in January 2018, with the Bill & Melinda Gates Foundation relating to our 
HIV program attributable to a supplemental award received in the first quarter of 2020, partially offset by $2.2 million recognized in the fourth quarter of 
2021 under the grant agreement entered into in November 2021 with the Bill & Melinda Gates Foundation.

The decrease in license revenue from a related party for the year ended December 31, 2021 compared to the same period in 2020 was due to the 

$22.7 million of revenue related to Brii Bio’s exercise of its option to obtain exclusive rights to develop and commercialize compounds arising from VIR-
2218 in greater China recognized in the prior year.

The increase in research and development expenses for the year ended December 31, 2021 compared to the same period in 2020 was primarily due 

to the following factors:

•

•

•

•

•

clinical costs increased by $67.8 million, which was primarily attributable to activities related to our sotrovimab, VIR-2218 and VIR-3434 
clinical trials;

personnel-related expenses increased by $52.2 million, which was primarily attributable to an increase in our headcount; 

licenses, collaborations and contingent consideration expenses increased by $22.0 million, which was primarily attributable to increases of 
$58.9 million in costs under our collaboration agreements with GSK, $9.2 million in fair value of the contingent consideration from our 
acquisition of Humabs Biomed SA, or Humabs, due to the achievement of certain milestones in 2021 as well as changes in assumptions and 
probabilities used in calculating the fair value of the remaining liability, and $1.0 million in third-party milestone payments, partially offset 
by decreases of $31.8 million due to achievement of the first development milestone under our amended collaboration agreement with 
Alnylam Pharmaceuticals, Inc., or the Amended Alnylam Agreement, in the first quarter of 2020, $10.0 million payment to Alnylam 
resulting from Brii Bio's exercise of its option for VIR-2218 in the second quarter of 2020, and $6.4 million in collaboration costs under our 
Amended Alnylam Agreement; 

other research and development expenses increased by $9.0 million, which was primarily attributable to increases of $6.4 million in the 
allocation of facilities and other costs due to an increase in our headcount and higher lease expense, and $2.7 million in sublicense fees due 
under a license agreement; and

contract manufacturing expense decreased by $5.4 million, which was primarily attributable to a decrease of $13.5 million in costs related to 
our COVID-19 product candidates mainly resulting from the completion of clinical manufacturing activities in the third quarter of 2020, 
partially offset by an increase of $8.2 million related to our HBV drug supply in the fourth quarter of 2021.

Selling, General and Administrative Expenses 

The increase in selling, general and administrative expenses for the year ended December 31, 2021 compared to the same period in 2020 was 
primarily due to increases of $39.4 million in fair value of the contingent consideration related to sales-based milestones from our acquisition of Humabs 
that were achieved in the fourth quarter of 2021, $39.0 million in personnel-related expenses resulting from additional headcount, and $10.6 million in 
external consulting services. 

Change in Fair Value of Equity Investments 

In July 2021, Brii Bio Parent became a publicly traded company on the Stock Exchange of Hong Kong Limited. In connection with the initial public 

offering, our investment in shares of Brii Bio Parent became a marketable equity investment and subsequently remeasured to fair value at each reporting 
period. For the year ended December 31, 2021, we recognized an unrealized gain of $138.0 million due to the change in fair value of the equity investment. 
No comparable amount was incurred for the same period in 2020.

Interest Income 

The decrease in interest income was primarily due to lower interest rates and higher amortization of premium on investment balances for the year 

ended December 31, 2021 compared to the same period in 2020.

Other Expense, Net 

The increase in other expenses for the year ended December 31, 2021 compared to the same period in 2020 was primarily related to the change in 

fair value of the contingent consideration related to our acquisition of TomegaVax. 

Provision for Income Taxes

The increase in provision for income taxes for the year ended December 31, 2021 compared to the same period in 2020 was primarily due to taxable 

income for 2021 attributable to significant collaboration revenue from the sale of sotrovimab as well as unrealized gain from the equity investment in Brii 
Bio Parent. 

Liquidity, Capital Resources and Capital Requirements 

Sources of Liquidity 

To date, we have financed our operations primarily through sales of our common stock from our initial public offering and follow-on offering; sales 

of our convertible preferred securities; and payments received under our grant and collaboration agreements. As of December 31, 2021, excluding 
restricted cash, we had $909.5 million cash, cash equivalents and investments, and after excluding the equity investment in Brii Bio Parent, we had $766.4 
million. In addition, as of December 31, 2021, we had a positive working capital balance and an accumulated deficit of $138.6 million. We have also 
entered into a sales agreement, or the Sales Agreement, with Cowen and Company, LLC, or Cowen, in 2020 pursuant to which we may from time to time 
offer and sell shares of our common stock for an aggregate offering price of up to $300.0 million, through or to Cowen, acting as sales agent or principal. 
We will pay Cowen a commission of up to 3.0% of the aggregate gross proceeds from each sale of shares, reimburse legal fees and disbursements and 
provide Cowen with customary indemnification and contribution rights. As of December 31, 2021, no shares have been issued under the Sales Agreement.

Our primary use of our capital resources is to fund our operating expenses, which consist primarily of expenditures related to identifying, acquiring, 
developing, manufacturing and in-licensing our technology platforms and product candidates, and conducting preclinical studies and clinical trials, and to a 
lesser extent, selling, general and administrative expenditures. 

Future Funding Requirements 

Based upon our current operating plan, we believe that our existing cash, cash equivalents and investments as of December 31, 2021 as noted above 

will enable us to fund our operations for at least the next 12 months. However, our operating plan may change as a result of many factors currently 
unknown to us, and we may need to seek additional financing to fund our long-term operations sooner than planned. Moreover, it is particularly difficult to 
estimate with certainty our future revenue and expenses given the dynamic and rapidly evolving nature of our business and the COVID-19 pandemic 
environment generally. We may also need to raise additional capital to complete the development and commercialization of our product candidates and 
fund certain of our existing manufacturing and other commitments. We anticipate raising additional capital through the sale of our equity securities, 
incurring debt, entering into collaboration, licensing or similar arrangements with third parties, or receiving research contributions, grants or other sources 
of financing to fund our operations. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership 
interest of our stockholders will be or could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect 
the rights of our common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting 
or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise funds 
through collaborations, licenses and other similar arrangements with third parties, we may have to relinquish valuable rights to our technologies, future 
revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us and/or may reduce the value of our 
common stock. There can be no assurance that sufficient funds will be available to us on attractive terms or at all. If we are unable to obtain additional 
funding from these or other sources, it may be necessary to significantly reduce our rate of spending through reductions in staff and delaying, scaling back, 
or stopping certain research and development programs. Insufficient liquidity may also require us to relinquish rights to product candidates at an earlier 
stage of development or on less favorable terms than we would otherwise choose. In addition, the COVID-19 pandemic 

132

 
continues to rapidly evolve and has already resulted in a significant disruption of global financial markets. If the disruption persists and deepens, we could 
experience an inability to access additional capital, which could in the future negatively affect our capacity for certain corporate development transactions 
or our ability to make other important, opportunistic investments. Market volatility, inflation, interest rate fluctuations and concerns related to the COVID-
19 pandemic may have a significant impact on the availability of funding sources and the terms on which any funding may be available.

We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all of our available 
capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development and commercialization of 
biotechnology products, we are unable to estimate the exact amount of our operating capital requirements. See the section titled “Risk Factors—Risks 
Related to Our Financial Position and Capital Needs” for a description of certain risks that will affect our future capital requirements. 

We have various operating lease arrangements for office and laboratory spaces located in California, Oregon, Missouri, and Switzerland with 

contractual lease periods expiring between 2022 and 2033. As of December 31, 2021, we expect to make total lease payments of $185.4 million through 
2033.

To date, we have entered into collaboration, license and acquisition agreements where the payment obligations are contingent upon future events 
such as our achievement of specified development, regulatory and commercial milestones, and we are required to make royalty payments in connection 
with the sale of products developed under those agreements. For additional information regarding these agreements, including our payment obligations 
thereunder, see the sections titled “Business—Our Collaboration, License and Grant Agreements” and “Business—Our Acquisition Agreements,” as well 
as Note 4—Acquisitions and Note 7—Collaboration and License Agreements to our consolidated financial statements included elsewhere in this Annual 
Report on Form 10-K. For information related to our future commitments under our facilities and manufacturing agreements, see Note 9—Commitments 
and Contingencies to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements.

Operating Activities 

During the year ended December 31, 2021, net cash used in operating activities was $47.6 million. This consisted primarily of net income of $528.6 

million and non-cash charges of $203.3 million, offset by an unrealized gain of $138.0 million on our equity investment, payment of contingent 
consideration of $8.1 million for the achievement of a milestone related to our TomegaVax acquisition, a gain of $4.8 million from a sublease termination, 
and an increase in our net operating assets of $628.4 million. The change in our net operating assets of $628.4 million was primarily due to an increase in 
receivable from collaboration by $773.1 million resulting from our profit share from the sale of sotrovimab, and an increase in prepaid expenses and other 
current assets of $3.7 million, partially offset by an increase in deferred revenue of $92.0 million driven by the upfront fee received under the 2021 GSK 
Agreement, and an increase in accrued liabilities and other long-term liabilities of $58.5 million due to timing of payments. The non-cash charges of $203.3 
million primarily consisted of $91.8 million for revaluation of contingent consideration, $83.8 million for stock-based compensation expense, $15.2 million 
for deferred income tax expense, $6.2 million for noncash lease expense, and $5.3 million for depreciation and amortization.

During the year ended December 31, 2020, net cash used in operating activities was $190.9 million. This consisted primarily of a net loss of $298.7 
million and payments on contingent consideration of $15.8 million related to the milestones achieved related to our Humabs acquisition, partially offset by 
a decrease in our net operating assets of $29.5 million and non-cash charges of $94.0 million. The change in our net operating assets of $29.5 million was 
primarily due to an increase in accrued liabilities and other long-term liabilities by $46.6 million, which was partially offset by a decrease in deferred 
revenue of $7.0 million related to revenue recognized from the Bill & Melinda Gates Foundation grants, a decrease in operating lease liabilities of $3.7 
million due to lease payments, and an increase of $4.5 million in prepaid expenses and other current assets primarily related to prepayment of clinical trial 
cost for our research and development activities. The non-cash charges of $94.0 million primarily consisted of $38.4 million for revaluation of contingent 
consideration related to our Humabs acquisition, $16.8 million for the change in fair value of the derivative liability under the Alnylam Agreement, $27.6 
million for stock-based compensation expense, and $4.4 million for depreciation and amortization. 

Investing Activities 

During the year ended December 31, 2021, net cash used in investing activities was $140.8 million. This consisted primarily of purchases of 
investments of $420.2 million and property and equipment of $21.8 million, partially offset by $301.2 million in proceeds received from investments that 
matured during the period.  

During the year ended December 31, 2020, net cash used in investing activities was $9.9 million. This consisted primarily of purchases of 

investments of $403.8 million and purchases of property and equipment of $6.5 million, partially offset by $400.3 million in proceeds received from 
investments which matured during the period.

Financing Activities 

During the year ended December 31, 2021, net cash provided by financing activities was $100.3 million. This consisted primarily of proceeds 

received from the issuance of our common stock to Glaxo Group Limited (an affiliate of GSK) of $85.2 million in March 2021, from exercises of stock 
options of $13.1 million, and from issuance of common stock under our employee stock purchase plan of $2.3 million.

During the year ended December 31, 2020, net cash provided by financing activities was $529.5 million. This consisted primarily of proceeds 
received from the issuance of our common stock to GSK of $206.7 million in April 2020, the issuance of our common stock related to our follow-on 
offering of $323.2 million and from exercises of stock options of $4.1 million, partially offset by payments of contingent consideration related to our 
Humabs acquisition of $4.2 million.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States. The 

preparation of our consolidated financial statements requires us to make assumptions and estimates about future events and apply judgments that affect the 
reported amounts of assets, liabilities, revenue and expenses and the related disclosures. We base our estimates on historical experience and other 
assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates. The critical accounting policies, 
estimates and judgments that we believe to have the most significant impacts to our consolidated financial statements are described below. For more detail 
on our critical accounting policies, refer to Note 2—Summary of Significant Accounting Policies to our consolidated financial statements appearing 
elsewhere in this Annual Report on Form 10-K.

Revenue Recognition

Collaboration, License and Contract Revenue

Under Accounting Standards Codification, or ASC, Topic 606, Revenue from Contracts with Customers, or ASC 606, we recognize revenue when 
our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those 
goods and services. To determine revenue recognition for arrangements within the scope of ASC 606, we perform the following five steps: (i) identify the 
contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price 
to the performance obligations in the contract; and (v) recognize revenue when or as we satisfy a performance obligation. 

For collaborative arrangements that fall within the scope of ASC 808, Collaborative Arrangements, or ASC 808, we first determine which elements 
of the collaboration are deemed to be a performance obligation with a customer within the scope of ASC 606. For elements of collaboration arrangements 
that are accounted for pursuant to ASC 808 and are not 

134

 
subject to the guidance in ASC 606, we apply the revenue recognition model under ASC 606 or other guidance, as deemed appropriate. When we are 
considered an agent in elements of collaboration arrangements within the scope of ASC 808, we record our share of collaboration revenue in the period in 
which such sales occur. We are considered an agent when the collaboration partner controls the product before transfer to the customers and has the ability 
to direct the use of and obtain substantially all of the remaining benefits from the product. In these instances, collaboration revenue is based upon the 
revenue reported by our collaboration partners, net of cost of goods sold and allowable expenses (e.g. medical affairs, selling and marketing expenses) in 
the period. In order to record collaboration revenue, we utilize certain information from our collaboration partner, including revenue from the sale of the 
product, and costs incurred for development and sales activities. For the periods covered in the financial statements presented, there have been no material 
changes to prior period estimates of revenues and expenses.

We have entered into a number of license and collaboration agreements that fall within the scope of ASC 606. We evaluate the promised goods or 

services in these agreements to determine which ones represent distinct performance obligations. These agreements may include the following types of 
promised goods or services: (i) grants of licenses, (ii) performance of research and development services, and (iii) participation on joint research and/or 
development committees. They also may include options to obtain licenses to our intellectual property. 

Prior to recognizing revenue, we make estimates of the transaction price, including variable consideration that is subject to a constraint. Amounts of 

variable consideration are included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue 
recognized will not occur and when the uncertainty associated with the variable consideration is subsequently resolved. These estimates are re-assessed 
each reporting period as required. These agreements may include the following types of consideration: non-refundable upfront payments, reimbursement 
for research services, research, development or regulatory milestone payments, profit-sharing arrangements, and royalty and commercial sales milestone 
payments. 

If there are multiple distinct performance obligations, we allocate the transaction price to each distinct performance obligation based on their 
estimated standalone selling prices, or SSP. We estimate the SSP for each distinct performance obligation by considering information such as market 
conditions, entity-specific factors, and information about our customer that is reasonably available to us. We consider estimation approaches that allow us 
to maximize the use of observable inputs. These estimation approaches may include the adjusted market assessment approach, the expected cost plus a 
margin approach or the residual approach. We also consider whether to use a different estimation approach or a combination of approaches to estimate the 
SSP for each distinct performance obligation. Developing various assumptions, including treatable patient population, expected market share, probability of 
success and product profitability, and discount rate based on weighted-average cost of capital, to determine the estimated SSP of a distinct performance 
obligation requires significant judgment. Accordingly, these assumptions are subject to uncertainty, and changing the methodology and/or assumptions 
could materially impact the estimated SSP for distinct performance obligations, and as a result, the amount and/or timing of revenue recognition.

For performance obligations satisfied over time, we estimate the efforts needed to complete the performance obligation and recognize revenue by 

measuring the progress towards complete satisfaction of the performance obligation using an input measure. For arrangements that include sales-based 
royalties, including commercial milestone payments based on pre-specified level of sales, we recognize revenue at the later of (i) when the related sales 
occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). Achievement 
of these royalties and commercial milestones may solely depend upon the performance of the licensee. 

Management may be required to exercise considerable judgment in estimating revenue to be recognized. Judgment is required in identifying 
performance obligations, estimating the transaction price, estimating the SSP of identified performance obligations, and estimating the progress towards 
satisfaction of performance obligations. 

Contingent Consideration and Embedded Derivatives

Contingent consideration related to business combinations and obligations required to be accounted for as embedded derivative financial 
instruments under Topic ASC 815, Derivatives and Hedging, are considered to be Level 3 instruments that are initially measured at their estimated fair 
values on the transaction date and subsequently remeasured with changes recorded in the consolidated statement of operations each subsequent reporting 
period.

The estimated fair value of the contingent consideration related to the Humabs acquisition was determined by calculating the probability-weighted 

clinical and regulatory milestone payments based on the assessment of the likelihood 

135

 
and estimated timing that certain milestones would be achieved, as well as the use of Monte Carlo simulation model that includes significant estimates and 
assumptions pertaining to commercialization events and sales targets. The most significant unobservable inputs are the probabilities of achieving clinical 
and regulatory approval of the development projects and the subsequent commercial success and discount rates. 

The estimated fair value of the contingent consideration related to our acquisition of TomegaVax was determined based on a Monte Carlo simulation 

model that includes significant estimates and assumptions pertaining to probability and timing to achieve the required share price of our common stock, 
expected volatility and discount rate. Although the TomegaVax acquisition was accounted for as an asset acquisition, such contingent consideration met the 
definition of an embedded derivative financial instrument. 

For the periods covered in the financial statements presented, there have been no material changes to prior period estimates of the fair value of our 

contingent consideration liability.

Recent Accounting Pronouncements Not Yet Adopted

See Note 2—Summary of Significant Accounting Policies to our consolidated financial statements included elsewhere in this Annual Report on 

Form 10-K for information about recent accounting pronouncements, the timing of their adoption, and our assessment, to the extent we have made one yet, 
of their potential impact on our financial condition or results of operations.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk. 

We are exposed to market risks in the ordinary course of our business. These risks primarily relate to interest rate and market price sensitivities.

Interest Rate Risk 

We had cash, cash equivalents and restricted cash and cash equivalents of $363.4 million as of December 31, 2021, which primarily consisted of 

money market funds. We also had short- and long-term investments of $418.6 million as of December 31, 2021. The primary objective of our investment 
activities is to preserve capital to fund our operations. We also seek to maximize income from our investments without assuming significant risk. Because 
our investments are primarily short-term in duration and our holdings in U.S. government treasury bonds mature prior to our expected need for liquidity, we 
believe that our exposure to interest rate risk is not significant, and a 1% movement in market interest rates would not have a significant impact on the total 
value of our portfolio. We had no debt outstanding as of December 31, 2021. 

Foreign Currency 

The functional currency of our foreign subsidiaries is the U.S. dollar. Monetary assets and liabilities of our foreign subsidiaries are translated into 

U.S. dollars at period-end exchange rates and non-monetary assets and liabilities are translated to U.S. dollars using historical exchange rates. Revenue and 
expenses are translated at average rates throughout the respective periods. As of the date of this Annual Report on Form 10-K, we are exposed to foreign 
currency risk primarily related to the operations of our Swiss and Australian subsidiaries and consequently the Swiss Franc and Australian dollar. 
Transaction gains and losses are included in other income (expenses), net on the consolidated statements of operations and were not material for the years 
ended December 31, 2021, 2020 and 2019. 

Equity Investment Risk

We hold ordinary shares of Brii Bio Parent, which we acquired in connection with our collaboration, option and license agreement. These equity 

securities are measured at fair value with any changes in fair value recognized in our consolidated statements of operations. The fair value of these equity 
securities was approximately $143.1 million as of December 31, 2021. Changes in the fair value of these equity securities are impacted by the volatility of 
the stock market and changes in general economic conditions, among other factors. A hypothetical 10% increase or decrease in the stock prices of these 
equity securities would increase or decrease their fair value as of December 31, 2021 by approximately $14.3 million.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors 
of Vir Biotechnology, Inc. 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Vir Biotechnology, Inc. (the Company) as of December 31, 2021 and 2020, the related 
consolidated statements of operations, comprehensive income (loss), convertible preferred stock and stockholders’ equity (deficit) and cash flows for each 
of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our 
opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, 
and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally 
accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s 
internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the 
Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) and our report dated February 28, 2022 expressed an unqualified 
opinion thereon.

Basis for Opinion 

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial 
statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the 
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the 
PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain 
reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included 
performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures 
that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the 
overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. 

Critical Audit Matter 

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or 
required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) 
involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion 
on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion 
on the critical audit matter or on the accounts or disclosures to which it relates.

Initial accounting for Stock Purchase Agreement with Glaxo Group Limited and Preliminary and Definitive 
Collaboration Agreement with Glaxo Wellcome UK Limited (collectively “2021 Expanded GSK Collaboration”) 

Description of the 
Matter

   As discussed in Note 7 to the consolidated financial statements, the Company entered into the 2021 Expanded GSK 

Collaboration. Auditing management’s initial application of the relevant US GAAP guidance under Accounting Standards 
Codification (ASC) 606, Revenue From Contracts With Customers and ASC 808, Collaborative Arrangements, related to 
the 2021 Expanded GSK Collaboration, was especially challenging due to the complex nature of its terms and conditions 
and the significant judgment required in estimating the standalone selling price for the identified performance obligations. 
In particular, the determination of estimated standalone selling price was based on various assumptions, including treatable 
patient population, expected market share, probability of success and product profitability. 

How We Addressed 
the Matter in Our 
Audit

   We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over management’s 

review of the terms and conditions of the 2021 Expanded GSK Collaboration and application of the appropriate accounting 
guidance. We also tested controls over management’s process to estimate the standalone selling price for the distinct 
performance obligations. For example, we tested controls over management’s review of the significant assumptions used to 
develop the standalone selling price estimates. We also tested controls to validate that the data used in the standalone selling 
price estimates were complete and accurate.

To test the Company’s application of the accounting guidance to the 2021 Expanded GSK Collaboration, we performed 
audit procedures that included, among others, reviewing the related contracts, obtaining direct confirmation of contract 
terms and conditions with GSK, assessing management’s application of the appropriate accounting guidance, evaluating the 
Company’s use of appropriate estimation methodologies with the assistance from a valuation specialist, evaluating 
sensitivity analyses to determine which assumptions had the greatest impact on the overall standalone selling price 
allocation, and testing the completeness and accuracy of the underlying data. Our procedures over the most significant 
assumptions included comparing assumptions to current industry, market, and economic trends. For example, we evaluated 
the probability of success rates used by considering the phase of development for the related programs at the transaction 
date and compared those rates to published industry benchmarks.

(“COVID-19”), hepatitis B virus (“HBV”), influenza A virus, and human immunodeficiency virus (“HIV”). Vir has assembled four technology platforms 
that are designed to stimulate and enhance the immune system by exploiting critical observations of natural immune processes.

In May 2021, the U.S. Food and Drug Administration (the "FDA") granted an Emergency Use Authorization (“EUA”) for sotrovimab for the early 
treatment of mild to moderate COVID-19 in adults and pediatric patients (12 years of age and older weighing at least 40 kg) with positive results of direct 
SARS-CoV-2 viral testing, and at high risk for progression to severe COVID-19, including hospitalization or death. The Company also received a positive 
scientific opinion from the Committee for Human Medicinal Products in the European Union (“EU”) for sotrovimab. In December 2021, the European 
Commission granted marketing authorization to Xevudy® (sotrovimab) in the EU for the treatment of adults and adolescents at increased risk of 
progressing to severe COVID-19. 

Initial Public Offering

On October 10, 2019, the Company completed its initial public offering (“IPO”) of its common stock. In connection with its IPO, the Company 

issued and sold 7,142,858 shares of its common stock at an initial offering price of $20.00 per share. As a result of the IPO, the Company received 
approximately $126.4 million in net proceeds, after deducting underwriting discounts, commissions and offering expenses. At the closing of the IPO, 
88,112,733 shares of outstanding convertible preferred stock were automatically converted into 88,112,733 shares of common stock and a warrant to 
purchase 244,444 shares of convertible preferred stock was converted into a warrant to purchase 244,444 shares of common stock. 

Follow-On Offering

On July 10, 2020, the Company issued and sold 8,214,285 shares of the Company’s common stock pursuant to a registration statement on Form S-1 
(File No. 333-239689) and a registration statement on Form S-1 filed pursuant to Rule 462(b) under the Securities Act of 1933, as amended (the “Securities 
Act”) (File No. 333-239747) (collectively, the “Registration Statements”). The Registration Statements became effective on July 7, 2020. The price of the 
shares sold in the follow-on offering was $42.00 per share and the Company received total gross proceeds from the offering of approximately $345.0 
million. After deducting underwriting discounts and commissions of approximately $20.7 million and offering expenses of approximately $1.1 million, the 
net proceeds were approximately $323.2 million.

Sales Agreement

In November 2020, the Company entered into a sales agreement (the “Sales Agreement”) with Cowen and Company, LLC (“Cowen”), under which 
the Company may from time to time offer and sell shares of its common stock for an aggregate offering price of up to $300.0 million, through or to Cowen, 
acting as sales agent or principal. The shares will be offered and sold under the Company’s shelf registration statement on Form S-3 (the “S-3 Registration 
Statement”) and a related prospectus filed with the Securities and Exchange Commission on November 10, 2020. The Company will pay Cowen a 
commission of up to 3.0% of the aggregate gross proceeds from each sale of shares, reimburse legal fees and disbursements and provide Cowen with 
customary indemnification and contribution rights. As of December 31, 2021, no shares have been issued under the Sales Agreement.

Notes to Consolidated Financial Statements 

Need for Additional Capital 

Although the Company recorded net income for the year ended December 31, 2021, it has otherwise incurred accumulated net losses since 
inception. The Company expects its earnings to be volatile and may continue to incur net losses over the next several years. As of December 31, 2021, the 
Company had an accumulated deficit of $138.6 million. Management expects to incur additional losses in the future to conduct research and development 
and recognizes the need to raise additional capital to fully implement its business plan. The Company had, excluding restricted cash, $909.5 million of 
cash, cash equivalents, and investments as of December 31, 2021, and after excluding the equity investment in Brii Biosciences Limited ("Brii Bio 
Parent"), the Company had $766.4 million. Based on the Company’s current operating plan, management believes that the $766.4 million as of December 
31, 2021 will be sufficient to fund its operations through at least the next 12 months from the issuance date of these consolidated financial statements.

Summary of Significant Accounting Policies 

Basis of Presentation 

The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United 

States of America (“GAAP”) and include all adjustments necessary for the fair presentation of the Company’s financial position for the periods presented. 
The consolidated financial statements include the accounts of Vir and its wholly-owned subsidiaries. All intercompany balances and transactions have been 
eliminated upon consolidation. 

Foreign Currency 

The functional currency of the Company’s foreign subsidiaries is the U.S. dollar. Monetary assets and liabilities of foreign subsidiaries are translated 
into U.S. dollars at period-end exchange rates and non-monetary assets and liabilities are translated to U.S. dollars using historical exchange rates. Revenue 
and expenses are translated at average rates throughout the respective periods. Transaction gains and losses are included in other income (expense), net on 
the consolidated statements of operations, and were immaterial for the years ended December 31, 2021, 2020 and 2019. 

Use of Estimates 

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that 

affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements and the 
reported amounts of revenue and expense during the reporting periods. The Company evaluates its estimates and assumptions on an ongoing basis using 
historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could materially 
differ from those estimates. 

Segments 

The Company operates as one reportable segment. The Company’s chief operating decision maker, its Chief Executive Officer, manages the 

Company’s operations on a consolidated basis for purposes of allocating resources. 

Concentration of Credit Risk, Credit Loss and Other Risks and Uncertainties

The Company has implemented a number of plans and policies designed to address and mitigate the impact of the ongoing COVID-19 pandemic on 
its business. The Company anticipates that the COVID-19 pandemic will continue to have an impact on the clinical development timelines for some of its 
clinical programs. The extent to which the COVID-19 pandemic impacts the Company’s business, clinical development and regulatory efforts, corporate 
development objectives and the value of and market for its common stock, will depend on future developments that are highly uncertain and cannot be 
predicted with confidence at this time, such as the ultimate duration of the pandemic, travel restrictions, quarantines, social distancing and business closure 
requirements in the United States, Europe and other countries, and the effectiveness of actions taken globally to contain and treat the disease.

Notes to Consolidated Financial Statements 

Although the Company received EUA, temporary authorization or marketing approval for sotrovimab (under the brand name Xevudy®), it is still 

subject to a number of other challenges and risks similar to other biopharmaceutical companies in the early stage, including, but not limited to, the need to 
obtain adequate additional funding, possible failure of preclinical testing or clinical trials, the need to obtain marketing approval for its other product 
candidates, competitors developing new technological innovations, the need to successfully commercialize and gain market acceptance of sotrovimab and 
other product candidates and protection of proprietary technology. If the Company does not successfully obtain regulatory approval, commercialize or 
partner any of its other product candidates, it will be unable to generate significant revenue from product sales or maintain profitability. In addition, to the 
extent the ongoing COVID-19 pandemic adversely affects the Company’s business and results of operations, it may also have the effect of heightening 
many of the other risks and uncertainties discussed above.

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents and 

investments. Cash and cash equivalents are deposited in checking and sweep accounts at a financial institution. Such deposits may, at times, exceed 
federally insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. 

The Company’s investment policy limits investments to certain types of securities issued by the U.S. government, its agencies and institutions with 

investment-grade credit ratings and places restrictions on maturities and concentration by type and issuer. The Company is exposed to credit risk in the 
event of a default by the financial institutions holding its cash, cash equivalents and investments, and issuers of the investments to the extent recorded on 
the consolidated balance sheets. As of December 31, 2021 and 2020, the Company has no off-balance sheet concentrations of credit risk.

The Company is exposed to credit losses primarily through receivables from customers and collaborators and through its available-for-sale debt 

securities. The Company’s expected loss allowance methodology for the receivables is developed using historical collection experience, current and future 
economic market conditions, a review of the current aging status and financial condition of the entities. Specific allowance amounts are established to 
record the appropriate allowance for customers that have a higher probability of default. Balances are written off when determined to be uncollectible. The 
Company’s expected loss allowance methodology for the debt securities is developed by reviewing the extent of the unrealized loss, the size, term, 
geographical location, and industry of the issuer, the issuers’ credit ratings and any changes in those ratings, as well as reviewing current and future 
economic market conditions and the issuers’ current status and financial condition. The Company considered the current and expected future economic and 
market conditions surrounding the COVID-19 pandemic and determined that the estimate of credit losses was not significantly impacted. There was no 
allowance for losses on available-for-sale debt securities attributable to credit risk for the years ended December 31, 2021 and 2020.

Cash Equivalents 

The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents, 

which consist of amounts invested in money market funds, are stated at fair value. 

Investments 

Investments include available-for-sale debt securities and equity investments, which are carried at estimated fair value. 

Available-for-Sale Debt Securities

The Company’s valuations of marketable securities are generally derived from independent pricing services based on quoted prices in active markets 
for similar securities at period end. Generally, investments with original maturities beyond three months at the date of purchase and which mature at, or less 
than 12 months from, the consolidated balance sheet date are considered short-term investments, with all others considered to be long-term investments. 
Unrealized gains and losses deemed temporary in nature are reported as a component of accumulated comprehensive income (loss). The amortized cost of 
debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, which is included in interest income on the consolidated 
statements of operations. The cost of securities sold is based on the specific identification method.

Notes to Consolidated Financial Statements 

Equity Investments

Under Accounting Standards Update ("ASU") No. 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and 
Financial Liabilities, the Company measures its investment in equity securities at fair value at each reporting date based on the market price at period end if 
it has a readily determinable fair value. Otherwise, the investments in equity securities are measured at cost less impairment, adjusted for observable price 
changes for identical or similar investments of the same issuer unless the Company has significant influence or control over the investee. Changes in fair 
value resulting from observable price changes are presented as change in fair value of equity investments and changes in fair value resulting from foreign 
currency translation are included in other income (expense), net on the consolidated statements of operations.

Restricted Cash and Cash Equivalents 

Restricted cash and cash equivalents represent money market funds to secure standby letters of credit and security deposits with financial 
institutions, both under office and laboratory space lease agreements. Additionally, funds received from certain grants are restricted as to their use and are 
therefore classified as restricted cash and cash equivalents. 

Property and Equipment, Net 

Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are computed using the 
straight-line method over the estimated useful lives of the respective assets, generally three to five years. Leasehold improvements are amortized over the 
lesser of their useful lives or the remaining life of the lease. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation 
and amortization are removed from the balance sheet and the resulting gain or loss is reflected in operations in the period realized. Maintenance and repairs 
are charged to operations as incurred. 

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset 

may not be recoverable. Recoverability is measured by comparing the carrying amount to the future net undiscounted cash flows which the assets are 
expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying 
amount of the assets exceeds the projected discounted future net cash flows arising from the asset. No material impairment losses have been incurred to 
date. 

Acquired Intangible Assets 

The Company’s intangible assets were acquired via business combinations or asset acquisitions. Indefinite-lived intangible assets represent the 

estimated fair value assigned to in-process research and development (“IPR&D”) acquired in a business combination. The Company reviews indefinite-
lived intangible assets for impairment at least annually or more frequently if events or changes in circumstances indicate that the carrying value of the 
assets might not be recoverable. If the carrying value of an indefinite-lived intangible asset exceeds its fair value, then it is written down to its adjusted fair 
value. As of December 31, 2021, there have been no such impairments. For IPR&D, if a product candidate derived from the indefinite-lived intangible 
asset is developed and commercialized, the useful life will be determined, and the carrying value will be amortized prospectively over that estimated useful 
life. Alternatively, if a product candidate is abandoned, the carrying value of the intangible asset will be charged to research and development expenses. 
IPR&D assets acquired as part of an asset acquisition are recorded at cost and expensed immediately if they have no alternative future uses.  

148

 
VIR BIOTECHNOLOGY, INC.

Notes to Consolidated Financial Statements 

Finite-lived intangible assets acquired are initially recognized at their fair value at the acquisition date. Amortization is computed using the straight-

line method over the estimated useful lives of the respective finite-lived intangible assets, generally seven to 15 years. Finite-lived intangible assets are 
reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. 

Goodwill 

Goodwill represents the excess of the purchase price over the estimated fair value of the net tangible and intangible assets acquired in a business 

combination. The Company tests goodwill for impairment at least annually or more frequently if events or changes in circumstances indicate that this asset 
may be impaired. 

Revenue Recognition 

Collaboration, License and Contract Revenue

Under Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), the Company recognizes 
revenue when the Company’s customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company 
expects to receive in exchange for those goods and services. To determine revenue recognition for arrangements within the scope of ASC 606, the 
Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) 
determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when or as the 
Company satisfies a performance obligation. 

For collaborative arrangements that fall within the scope of ASC 808, Collaborative Arrangements (“ASC 808”), the Company first determines 

which elements of the collaboration are deemed to be a performance obligation with a customer within the scope of ASC 606. For elements of 
collaboration arrangements that are accounted for pursuant to ASC 808 and are not subject to the guidance in ASC 606, the Company applies the revenue 
recognition model under ASC 606 or other guidance, as deemed appropriate. When the Company is considered an agent in elements of collaboration 
arrangements within the scope of ASC 808, it records its share of collaboration revenue in the period in which such sales occur. The Company is 
considered an agent when the collaboration partner controls the product before transfer to the customers and has the ability to direct the use of and obtain 
substantially all of the remaining benefits from the product. In these instances, collaboration revenue is based upon the revenue reported by the Company's 
collaboration partners, net of cost of goods sold and allowable expenses (e.g. medical affairs, selling and marketing expenses) in the period. In order to 
record collaboration revenue, the Company utilizes certain information from its collaboration partner, including revenue from the sale of the product, and 
costs incurred for development and sales activities. For the periods covered in the financial statements presented, there have been no material changes to 
prior period estimates of revenues and expenses.

The Company has entered into a number of license and collaboration agreements that fall within the scope of ASC 606. The Company evaluates the 

promised goods or services in these agreements to determine which ones represent distinct performance obligations. These agreements may include the 
following types of promised goods or services: (i) grants of licenses, (ii) performance of research and development services, and (iii) participation on joint 
research and/or development committees. They also may include options to obtain licenses to the Company’s intellectual property. 

Prior to recognizing revenue, the Company makes estimates of the transaction price, including variable consideration that is subject to a constraint. 

Amounts of variable consideration are included in the transaction price to the extent that it is probable that a significant reversal in the amount of 
cumulative revenue recognized will not occur and when the uncertainty associated with the variable consideration is subsequently resolved. These 
estimates are re-assessed each reporting period as required. These agreements may include the following types of consideration: non-refundable upfront 
payments, reimbursement for research services, research, development or regulatory milestone payments, profit-sharing arrangements, and royalty and 
commercial sales milestone payments. 

149

 
VIR BIOTECHNOLOGY, INC.

Notes to Consolidated Financial Statements 

If there are multiple distinct performance obligations, the Company allocates the transaction price to each distinct performance obligation based on 

their estimated standalone selling prices (“SSP”). The Company estimates the SSP for each distinct performance obligation by considering information 
such as market conditions, entity-specific factors, and information about its customer that is reasonably available. The Company considers estimation 
approaches that allow it to maximize the use of observable inputs. These estimation approaches may include the adjusted market assessment approach, the 
expected cost plus a margin approach or the residual approach. The Company also considers whether to use a different estimation approach or a 
combination of approaches to estimate the SSP for each distinct performance obligation. Developing certain assumptions (e.g., treatable patient population, 
expected market share, probability of success and product profitability, discount rate based on weighted-average cost of capital) to estimate the SSP of a 
distinct performance obligation requires significant judgment.

For performance obligations satisfied over time, the Company estimates the efforts needed to complete the performance obligation and recognizes 

revenue by measuring the progress towards complete satisfaction of the performance obligation using an input measure. 

For arrangements that include sales-based royalties, including commercial milestone payments based on pre-specified level of sales, the Company 

recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been 
allocated has been satisfied (or partially satisfied). Achievement of these royalties and commercial milestones may solely depend upon the performance of 
the licensee. 

Grant Revenue 

Grants received, including cost reimbursement agreements, are assessed to determine if the agreement should be accounted for as an exchange 
transaction or a contribution. An agreement is accounted for as a contribution if the resource provider does not receive commensurate value in return for the 
assets transferred. Contributions are recognized as grant revenue when all donor-imposed conditions have been met. 

Research and Development Expenses 

To date, research and development expenses have related primarily to discovery efforts and preclinical and clinical development of product 

candidates. Research and development expenses are recognized as incurred and payments made prior to the receipt of goods or services to be used in 
research and development are capitalized until the goods or services are received. Research and development expenses include expenses related to license 
and collaboration agreements; contingent consideration from business acquisitions; personnel-related expenses, including salaries, benefits, and stock-
based compensation for personnel contributing to research and development activities; expenses incurred under agreements with third-party contract 
manufacturing organizations, contract research organizations, and consultants; clinical costs, including laboratory supplies and costs related to compliance 
with regulatory requirements; and other allocated expenses, including expenses for rent, facilities maintenance, and depreciation and amortization. 

The Company has and may continue to acquire the rights to develop and commercialize new product candidates from third parties. Upfront 
payments and research and development milestone payments made in connection with acquired license or product rights are expensed as incurred, provided 
that they do not relate to a regulatory approval milestone or assets acquired in a business combination. 

The Company’s expense accruals for clinical trials and manufacturing are based on estimates of contracted services provided by third-party vendors 

not yet billed. When billing terms under these contracts do not coincide with the timing of when the work is performed, the Company is required to make 
estimates of its outstanding obligations to those third parties as of the period end. The accrual estimates are based on a number of factors, including the 
Company’s knowledge of the research and development programs and clinical manufacturing activities, the status of the programs and activities, invoicing 
to date, and the provisions in the contracts. The Company obtains information regarding unbilled services directly from these service providers and 
performs procedures to support its estimates based on its internal understanding of the services provided to date. However, the Company may also be 
required to estimate these services based on information available to its internal clinical and manufacturing administrative staff if such information is not 
able to be obtained timely from its service providers.

Notes to Consolidated Financial Statements 

Stock-based Compensation 

The Company recognizes stock-based compensation to employees and non-employees over the requisite service period based on the grant-date fair 

value of the awards. The Company calculates the estimated fair value of stock options and employees' purchase rights under the Company's 2019 employee 
stock purchase plan ("ESPP") using the Black-Scholes valuation model, which requires the use of subjective assumptions including volatility and expected 
term, among others. The fair value of restricted stock awards ("RSAs") and restricted stock units ("RSUs") is based on the market value of the Company's 
common stock on the date of grant. Stock-based compensation is recognized using the straight-line method for awards that vest only upon the employee’s 
or non-employee’s continued service to the Company. Stock-based compensation expense of the employees' purchase rights under the ESPP is recognized 
over the offering period. Forfeitures are recognized as they occur. 

Acquisitions 

Business combinations are accounted for using the acquisition method of accounting. Under the acquisition method, assets acquired, including 

IPR&D projects, and liabilities assumed are recorded at their respective fair values as of the acquisition date. Any excess fair value of consideration 
transferred over the fair value of the net assets acquired is recorded as goodwill. Contingent consideration obligations incurred in connection with the 
business combination are recorded at their fair values on the acquisition date and are remeasured each subsequent reporting period until the related 
contingencies are resolved and are classified as contingent consideration on the consolidated balance sheets. The changes in fair values of contingent 
consideration related to the achievement of various milestones are recorded within research and development expenses or selling, general and 
administrative expenses based on the nature of the relevant underlying activities.    

When the Company determines that entities acquired do not meet the definition of a business, the transaction is accounted for as an acquisition of 

assets. Therefore, the consideration paid to acquire IPR&D is expensed, and no goodwill is recorded. Any contingent consideration is generally recognized 
only when it becomes payable or is paid. 

Embedded Derivatives

The Company evaluates its acquisitions, collaborative arrangements and other business development transactions to determine if embedded 
components of these contracts meet the definition of a derivative under ASC 815, Derivatives and Hedging. In general, embedded derivatives are required 
to be bifurcated from the host instrument if (i) the embedded feature is not clearly and closely related to the host contract and (ii) the embedded feature, if 
considered a freestanding instrument, meets the definition of a derivative. Embedded derivatives are reported on the consolidated balance sheets at their 
estimated fair values. Contingent consideration related to asset acquisitions that meet the definition of an embedded derivative is classified as contingent 
consideration on the consolidated balance sheets. Any change in estimated fair values, as determined at each measurement period, are recorded in the 
consolidated statements of operations based on the nature of the related contingencies. Changes in fair values of embedded derivatives related to the 
achievement of various milestones for product candidates are recorded within research and development expense or selling, general and administrative 
expenses based on the nature of the relevant underlying activities. Otherwise, changes in fair values are recorded within other income (expense), net.

Leases 

In accordance with ASU No. 2016-02 (Topic 842), Leases, the Company determines if an arrangement is or contains a lease at inception by 

assessing whether the arrangement contains an identified asset and whether it has the right to control the identified asset. Right-of-use ("ROU") assets 
represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments 
arising from the lease. Lease liabilities are recognized at the lease commencement date based on the present value of future lease payments over the lease 
term. ROU assets are based on the measurement of the lease liability and also include any lease payments made prior to or on lease commencement and 
exclude lease incentives and initial direct costs incurred, as applicable. On the lease commencement date, the Company estimates and includes in its lease 
payments any lease incentive amounts based on future events when (1) the events are within the Company’s control and (2) the event triggering the right to 
receive the incentive is deemed reasonably certain to occur. If the lease incentive received is greater or less than the amount recognized at lease 
commencement, the Company recognizes the difference as an adjustment to right-of-use asset and/or lease liability, as applicable.

151

 
VIR BIOTECHNOLOGY, INC.

Notes to Consolidated Financial Statements 

As the implicit rate in the Company's leases is generally unknown, the Company uses an incremental borrowing rate estimated based on the 

information available at the lease commencement date in determining the present value of future lease payments. When calculating its estimated 
incremental borrowing rates, the Company considers its credit risk, the lease term, the total lease payments and the impact of collateral, as necessary. The 
lease terms may include options to extend or terminate the lease when the Company is reasonably certain it will exercise such options. ROU assets and 
lease liabilities are remeasured upon certain modifications to leases using the present value of remaining lease payments and estimated incremental 
borrowing rate upon lease modification. Rent expense for the Company's operating leases is recognized on a straight-line basis within operating expenses 
over the reasonably assured lease term.

The Company elected to not separate lease and non-lease components for any leases within its existing classes of assets and, as a result, accounts for 

the lease and non-lease components as a single lease component. The Company has also elected to not apply the recognition requirement to any leases 
within its existing classes of assets with a term of 12 months or less.

Income Taxes 

The Company uses the asset and liability method of accounting for income taxes. Current income tax expense or benefit represents the amount of 

income taxes expected to be payable or refundable for the current year. Deferred income tax assets and liabilities are determined based on differences 
between the financial statement reporting and tax bases of assets and liabilities and net operating losses and credit carryforwards and are measured using 
the enacted tax rates and laws that will be in effect when such items are expected to reverse. Deferred income tax assets are reduced, as necessary, by a 
valuation allowance when management determines it is more likely than not that some or all of the tax benefits will not be realized. 

The Company’s tax positions are subject to income tax audits. The Company recognizes the tax benefit of an uncertain tax position only if it is more 

likely than not that the position is sustainable upon examination by the taxing authority, based on the technical merits. The tax benefit recognized is 
measured as the largest amount of benefit which is more likely than not to be realized upon settlement with the taxing authority. The Company evaluates 
uncertain tax positions on a regular basis. The evaluations are based on several factors, including changes in facts and circumstances, changes in tax law, 
correspondence with tax authorities during the course of the audit, and effective settlement of audit issues. The provision for income taxes includes the 
effects of any accruals that the Company believes are appropriate, as well as any related net interest and penalties. 

Net Income (Loss) Per Share 

Basic net income (loss) per common share is computed by dividing the net income (loss) by the weighted-average number of common shares 
outstanding during the period, without consideration of common stock equivalents. Diluted net income per common share is computed by dividing the net 
income by the sum of the weighted average number of common shares outstanding during the period plus any potential dilutive effects of common stock 
equivalents outstanding during the period calculated in accordance with the treasury stock method. 

New Accounting Pronouncement Not Yet Adopted 

In November 2021, the Financial Accounting Standards Board ("FASB") issued ASU No. 2021-10, Government Assistance (Topic 832) (“ASU 

2021-10”), which adds certain disclosure requirements with respect to government assistance, including (1) the types of assistance, (2) an entity’s 
accounting for the assistance, and (3) the effect of the assistance on financial statements. ASU 2021-10 is effective for annual periods beginning after 
December 15, 2021. Early adoption is permitted. The Company is currently evaluating the impact the adoption of ASU 2021-10 may have on its 
consolidated financial statements and related disclosures.

Fair Value Measurements 

The Company determines the fair value of financial and non-financial assets and liabilities using the fair value hierarchy, which establishes three 

levels of inputs that may be used to measure fair value, as follows: 

•

•

•

Level 1: Inputs which include quoted prices in active markets for identical assets and liabilities. 

Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted 
prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the 
full term of the assets or liabilities. 

Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or 
liabilities. 

The carrying amounts of the Company’s financial instruments, including receivable from collaboration, accounts payable and accrued liabilities 

approximate fair value due to their relatively short maturities. 

Cash Equivalents and Available-for-Sale Debt Securities

Accrued interest receivable excluded from both the fair value and amortized cost basis of the available-for-sale debt securities are presented within 

prepaid expenses and other current assets, and other assets in the consolidated balance sheets. Accrued interest receivable amounted to $1.1 million and 
$0.8 million as of December 31, 2021 and 2020, respectively. The Company did not write off any accrued interest receivable during the years ended 
December 30, 2021 and 2020. 

The Company recognized total net unrealized loss of $0.9 million and net unrealized gain of $0.1 million in accumulated other comprehensive 
income (loss) as of December 31, 2021 and 2020, respectively. The gross unrealized losses related to U.S. government treasuries as of December 31, 2021 
were due to changes in interest rates. As of December 31, 2021 and 2020, there were no investments that have been in a continuous unrealized loss position 
for longer than 12 months. The Company determined that the gross unrealized losses on our investments as of December 31, 2021 were temporary in 
nature. The Company currently does not intend, and it is highly unlikely that it will be required, to sell these securities before recovery of their amortized 
cost basis. As of December 31, 2021, no securities have contractual maturities of longer than two years.

Notes to Consolidated Financial Statements 

Equity Investments 

As of December 31, 2021, the Company's equity investment consisted solely of ordinary shares of Brii Bio Parent. The Company acquired the 

securities as partial consideration for entering into the collaboration, option and license agreement (the “Brii Agreement”) with Brii Bio Parent and Brii 
Biosciences Offshore Limited (“Brii Bio”) in May 2018. The Company concluded it does not have a controlling interest or significant influence over Brii 
Bio based on its ownership percentage and other factors. See further discussion in Note 7—Collaboration and License Agreements. In July 2021, Brii Bio 
Parent completed its initial public offering ("Brii Bio Parent IPO") on the Stock Exchange of Hong Kong Limited, prior to which the securities were 
accounted for as equity securities without a readily determinable fair value. Upon the completion of the Brii Bio Parent IPO, the securities were considered 
to be marketable equity securities and subsequently remeasured at fair value at each reporting date. The Company classifies its equity investment in Brii 
Bio Parent as a Level 1 asset within the fair value hierarchy, as the value is based on a quoted market price in an active market. As of December 31, 2021, 
the Company remeasured the equity investment at a fair value of $143.1 million. For the year ended December 31, 2021, the Company recognized an 
unrealized gain of $138.0 million as other income in the consolidated statement of operations, net of an unrealized loss of $0.6 million related to foreign 
currency translation for the period.

Contingent Consideration 

Contingent consideration includes potential milestone payments in connection with the acquisitions of Humabs Biomed SA (“Humabs”) and 
TomegaVax, Inc. (“TomegaVax”). See further discussion in Note 4—Acquisitions. The Company classifies the contingent consideration as Level 3 
financial liabilities within the fair value hierarchy as of December 31, 2021 and 2020.

The estimated fair value of the contingent consideration related to the Humabs acquisition was determined by calculating the probability-weighted 
clinical, regulatory, and commercial milestone payments based on the assessment of the likelihood and estimated timing that certain milestones would be 
achieved. In December 2021, the Company achieved the regulatory milestone of $35.0 million related to sotrovimab. As of December 31, 2021, the 
Company calculated the estimated fair value of the remaining clinical and regulatory milestones related to the HBV product using the following significant 
unobservable inputs: 

Discount rates
Probability of achievement

Unobservable input

(1) Unobservable inputs were weighted based on the relative fair value of the clinical and regulatory milestone payments. 

Range
(Weighted-Average)1
3% - 5% (4%)
22% - 40% (31%)

For the commercial milestones, the Company used a Monte Carlo simulation because of the availability of a discrete revenue forecast. During the 

year ended December 31, 2021, the Company achieved the specified sales milestones totaling $60.0 million related to sotrovimab. As of December 31, 
2021, the Monte Carlo simulation assumed a commercial product launch and associated discrete revenue forecast, as well as the following significant 
unobservable inputs for the remaining commercial milestones related to the HBV product: 

Volatility
Discount rate
Probability of achievement

Unobservable input

Value
65%
11%
22%

The discount rate captures the credit risk associated with the payment of the contingent consideration when earned and due. As of December 31, 

2021 and 2020, the estimated fair value of the contingent consideration related to the Humabs acquisition was $17.1 million and $29.2 million, 
respectively, with changes in the estimated fair value recorded in research and development expense, and selling, general and administrative expense in the 
consolidated statements of operations.

The estimated fair value of the contingent consideration related to the TomegaVax acquisition was determined by using a Monte Carlo simulation 

model which included estimates of both the probability and timing to achieve the required per share price of the Company’s common stock, and 
incorporates assumptions as to expected volatility and discount rate. The discount rate captures the credit risk associated with the payment of the contingent 
consideration when earned and due. Although the TomegaVax acquisition was accounted for as an asset acquisition, such contingent consideration met the

definition of an embedded derivative financial instrument. In February 2021, the Company achieved one of the milestones related to a specified per-share 
price of its common stock resulting in a $10.0 million payable to the former TomegaVax’s stockholders which was paid in July 2021. As of December 31, 
2021, the fair value of the remaining contingent consideration was estimated using the following significant unobservable inputs:

As of December 31, 2021 and 2020, the estimated fair value of the contingent consideration related to the TomegaVax acquisition was $5.7 million 
and $6.8 million, respectively, with changes in the estimated fair value recorded in other income (expense), net in the consolidated statements of operations.

The estimated fair value of the contingent consideration related to the Humabs and TomegaVax acquisitions involves significant estimates and 

assumptions which give rise to measurement uncertainty.

Acquisitions 

Acquisition of TomegaVax 

In September 2016, the Company entered into an agreement and plan of merger (“TomegaVax Merger Agreement”) to acquire all of the equity 

interests of TomegaVax. The primary asset purchased in the acquisition was an in-process cytomegalovirus vector-based vaccine platform for use in HBV, 
HIV, and tuberculosis. The acquisition was accounted for as an asset purchase. The Company recorded the cash purchase price of $5.2 million in research 
and development expenses and incurred transaction costs of $0.5 million in 2016.

In connection with the entry into the TomegaVax Merger Agreement, the Company also entered into a letter agreement with TomegaVax (the 
“TomegaVax Letter Agreement”), which provides for certain payments to TomegaVax’s former stockholders before September 2024, in each case so long 
as the Company is continuing to pursue the development of the TomegaVax technology. Under the terms of the TomegaVax Letter Agreement, the 
Company will be required to pay to the former stockholders of TomegaVax milestone payments of up to an aggregate of $30.0 million if the per-share price 
of the Company’s publicly traded common stock, or implied price per-share of the Company’s Series A-1 convertible preferred stock (or common stock 
upon conversion) upon a certain asset sale, merger or stock sale, is at least $45 (as adjusted in the case of any stock dividend, stock split or other similar 
recapitalization), with the amount of such payments determined by the share price and/or the stage of the Company’s clinical development at the time of the 
relevant event triggering the payment. The share price of the Company’s publicly traded common stock will be determined using the average of the daily 
volume-weighted average trading price of the Company’s common stock for each trading day during a consecutive 90-day period. The foregoing payments 
are payable (i) during any date after the completion of an initial public offering by the Company or any successor or affiliate controlling the TomegaVax 
technology, provided that no payment will be due before the first anniversary of the initial public offering, (ii) upon the sale of all assets related to the 
TomegaVax technology or (iii) upon a merger or stock sale of the Company or any successor or affiliate controlling the TomegaVax technology, in each 
case subject to certain conditions with respect to the timing of the payments. The payments under the TomegaVax Letter Agreement can be made in cash or 
shares of the Company’s common stock, at the discretion of the Company’s board of directors.

Notes to Consolidated Financial Statements 

In February 2021, the Company achieved one of the milestones related to the specified per-share price of its common stock, which resulted in a 

$10.0 million payable to TomegaVax’s former stockholders. In July 2021, the Company made the milestone payment to the former TomegaVax 
stockholders through a combination of $8.1 million in cash and the issuance of 42,737 shares of common stock with a total fair value of $1.9 million. The 
remaining milestone payments of up to $20.0 million in the aggregate will be triggered if (i) the per-share price of the Company’s publicly traded common 
stock is at least $45 (as adjusted in the case of any stock dividend, stock split or other similar recapitalization) and upon the achievement of a certain 
milestone related to the stage of the Company’s clinical development at the time of the relevant event triggering the payment and/or (ii) the per-share price 
of the Company’s publicly traded common stock is at least $90 (as adjusted in the case of any stock dividend, stock split or other similar recapitalization).

The Company determined that the future milestone payments contain net settlement provisions and therefore, they were required to be accounted for 
as embedded derivatives under the relevant accounting guidance. As of December 31, 2021, the fair value of the embedded derivative was $5.7 million and 
is included in the contingent consideration liability on the consolidated balance sheet. 

Acquisition of Humabs 

In August 2017, the Company acquired all of the outstanding equity of Humabs, a private Swiss company, which discovers and develops 

monoclonal antibodies (“mAbs”) derived from individuals whose immune systems have successfully responded to major diseases. The Company acquired 
all of Humabs’ rights, title and interest in and to substantially all of the assets of Humabs except for rights under certain license agreements with third 
parties. The Company is obligated to pass through to the former Humabs shareholders any amounts received by Humabs under such license agreements, 
net of any program expenses. The transaction was accounted for as an acquisition of a business. The consideration paid consisted of $30.0 million in cash 
and 1,666,656 shares of common stock, valued at $2.5 million as of the date of the transaction, to former Humabs shareholders. In addition to the cash 
payment and issuance of common stock to the former Humabs shareholders at the acquisition date, the Company also agreed to pay additional amounts in 
cash upon the achievement of specified milestone events: (i) up to $135.0 million upon the achievement of clinical, regulatory and commercial milestones 
for an HBV product; and (ii) up to $105.0 million upon the achievement of clinical, regulatory and commercial milestones for another product, which the 
Company elected as a severe acute respiratory syndrome coronavirus 2 (“SARS-CoV-2”) product, or sotrovimab. 

During the year ended December 31, 2020, the Company achieved two of the specified clinical milestones for the HBV product and sotrovimab 
totaling $20.0 million. During the year ended December 31, 2021, the Company achieved the specified regulatory milestone of $35.0 million and sales 
milestones totaling $60.0 million related to sotrovimab. The estimated fair value of the remaining contingent consideration was $17.1 million as of 
December 31, 2021. The Company paid the $35.0 million milestone and $60.0 million milestone in January and February 2022, respectively. 

The acquired developed technologies that have associated patents issued are classified as finite-lived intangible assets and are amortized on a 
straight-lined basis over their estimated remaining useful lives, generally between seven to 12 years. The Company also acquired indefinite-lived intangible 
assets consisting of IPR&D. These assets will not be amortized until regulatory approval is obtained in a major market. At that time, the Company will 
determine the useful life of the asset and begin amortization. If the associated research and development effort is abandoned or otherwise impaired, the 
related IPR&D assets will be written-off and an impairment charge recorded. As of December 31, 2021, there have been no such impairments related to the 
IPR&D assets. The estimated fair value of the intangible assets was determined using the replacement cost method. The excess of the purchase price over 
the estimated fair value of the net assets acquired was recorded as goodwill. None of the goodwill is expected to be deductible for income tax purposes.

5.

Goodwill and Intangible Assets 

Goodwill 

Goodwill of $16.9 million represents the excess of the purchase price over the estimated fair value of the net assets acquired from Humabs. The 
Company tests goodwill for impairment on an annual basis or sooner, if deemed necessary. There was no impairment for the year ended December 31, 
2021.

Finite-lived intangible assets are carried at cost less accumulated amortization. The contract-based intangible asset resulted from the product 

approval of a sublicensed intellectual property right in December 2020. The intellectual property right was previously accounted for as IPR&D. 
Amortization expense related to finite-lived intangible assets, included in research and development expenses on the consolidated statements of operations, 
totaled $0.5 million, $1.0 million and $1.2 million for the years ended December 31, 2021, 2020 and 2019, respectively. 

Management reviews finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount 

may not be recoverable, like that of property and equipment. During the third quarter of 2020, as a result of the availability of other research and analytics 
platforms, the Company abandoned certain of its acquired developed technologies and concluded that the full remaining book values of the assets were 
impaired. Therefore, $0.8 million was written off as an impairment charge, which was classified as research and development expenses during 2020. 

Based on the finite-lived intangible assets recorded as of December 31, 2021, the estimated future amortization expense for the next five years is as

As of December 31, 2021 and 2020, the Company had indefinite-lived intangible assets of $30.7 million, respectively, related to the purchased 
IPR&D from the Humabs acquisition. In December 2020, $0.5 million was reclassed as a finite-lived intangible asset due to the product approval of a 
sublicensed intellectual property right. No impairment losses have been recorded for the years ended December 31, 2021 and 2020.

Payments received in advance that were related to future research activities were deferred and recognized as revenue when the donor-imposed 
conditions were met, which was as the research and development activities were performed. The Company recognized grant revenue of $0.9 million for the 
year ended December 31, 2019. 

HIV Grant 

On January 26, 2018, the Company entered into a grant agreement with the Bill & Melinda Gates Foundation under which it was awarded a grant 
totaling up to $12.2 million for its HIV program (the “HIV Grant”). In February 2020, the parties amended the HIV Grant under which the Company was 
awarded a supplemental grant of $8.6 million. In June 2021, the parties further amended the agreement under which the grant term was extended from 
December 31, 2021 to October 31, 2022, unless earlier terminated by the Bill & Melinda Gates Foundation for the Company’s breach, failure to progress 
the funded project, in the event of the Company’s change of control, change in the Company’s tax status, or significant changes in the Company’s 
leadership that the Bill & Melinda Gates Foundation reasonably believes may threaten the success of the project.  

In December 2020, the Company achieved a specified milestone under the HIV Grant which triggered a $1.9 million payment from the Bill & 

Melinda Gates Foundation. As of December 31, 2020, the Company recorded a receivable, which is included within prepaid expenses and other current 
assets, and current portion of deferred revenue for the $1.9 million, which was subsequently received in January 2021. 

Payments received in advance that are related to future research activities are deferred and recognized as revenue when the donor-imposed 

conditions are met, which is as the research and development activities are performed. The Company recognized grant revenue of $3.0 million, $6.4 million 
and $3.7 million for the years ended December 31, 2021, 2020 and 2019, respectively. As of December 31, 2021 and 2020, the Company has deferred 
revenue of $2.3 million and $3.8 million, respectively, under HIV Grant. 

Tuberculosis (“TB”) Grant 

On March 16, 2018, the Company entered into a grant agreement with the Bill & Melinda Gates Foundation under which it was awarded a grant 

totaling up to $14.9 million for its TB program (the “TB Grant”). The parties amended the agreement in May 2020, in June 2021 and in December 2021 to 
extend the grant term. The TB Grant will remain in effect until March 31, 2022, unless earlier terminated by the Bill & Melinda Gates Foundation for the 
Company’s breach, failure to progress the funded project, in the event of the Company’s change of control, change in the Company’s tax status, or 
significant changes in the Company’s leadership that the Bill & Melinda Gates Foundation reasonably believes may threaten the success of the project. As 
of December 31, 2021, the Company had $1.8 million of unused funds received in advance and previously recorded as deferred revenue within accrued and 
other liabilities. As of December 31, 2021 and 2020, the Company has deferred revenue of $1.3 million and $2.6 million, respectively, under TB Grant.

Payments received in advance that are related to future research activities are deferred and recognized as revenue when the donor-imposed 

conditions are met, which is as the research and development activities are performed. The Company recognized grant revenue of $3.0 million, $2.2 million 
and $1.9 million for the years ended December 31, 2021, 2020 and 2019, respectively.  

HCMV-Vaccine Platform Grant 

On November 5, 2021, the Company entered into a grant agreement with the Bill & Melinda Gates Foundation under which it was awarded a grant 
totaling up to $10.0 million to support the manufacturing and clinical activities of its HIV and TB vaccine programs. This grant agreement will remain in 
effect until August 30, 2023, unless earlier terminated by the Bill & Melinda Gates Foundation for the Company’s breach, failure to progress the funded 
project, in the event of the Company’s change of control, change in the Company’s tax status, or significant changes in the Company’s leadership that the 
Bill & Melinda Gates Foundation reasonably believes may threaten the success of the project.

Payments received in advance that are related to future research activities are deferred and recognized as revenue when the donor-imposed 
conditions are met, which is as the research and development activities are performed. The Company recognized grant revenue of $2.2 million for the year 
ended December 31, 2021. As of December 31, 2021, the Company has deferred revenue of $3.3 million under this grant agreement.

National Institutes of Health 

As part of the Company’s acquisition of TomegaVax in September 2016, the Company acquired grant agreements related to TomegaVax’s research 

effort in infectious diseases and cancer that entitled them to several awards under the Small Business Innovation Research Program from the National 
Institutes of Health (“NIH”). Through July 2021, the Company has acquired or been awarded grants from NIH totaling $5.1 million. These grants were cost 
plus fixed fee agreements in which the Company was reimbursed for its direct and indirect costs. Only costs that were allowable under certain government 
regulations and NIH’s supplemental policy and procedure manual may be claimed for reimbursement, subject to government audit. 

The Company recognized grant revenue of $0.1 million, $0.6 million and $0.9 million for the years ended December 31, 2021, 2020 and 2019,

Collaboration and License Agreements 

Collaboration Agreements with GSK 

2020 GSK Agreement

On June 9, 2020, the Company, Glaxo Wellcome UK Limited and Beecham S.A. (referred to individually and together, as “GSK”) entered into a 

definitive collaboration agreement under the terms set forth in the preliminary collaboration agreement entered into by the Company and certain GSK 
entities in April 2020 (the “2020 Preliminary Agreement”) (such definitive collaboration agreement, the “2020 GSK Agreement”). Concurrently with the 
execution of the 2020 Preliminary Agreement, the Company entered into a stock purchase agreement (the “2020 Stock Purchase Agreement”) with Glaxo 
Group Limited (“GGL”), an affiliate of GSK, under which GGL purchased 6,626,027 shares of the Company’s common stock on April 29, 2020, at a price 
per share of $37.73, for an aggregate purchase price of approximately $250.0 million. After receipt of antitrust clearance on April 22, 2020, the 2020 
Preliminary Agreement became effective as of April 29, 2020, which was also the closing date for the associated 2020 Stock Purchase Agreement between 
the parties (“Effective Date”). Under the terms of the 2020 GSK Agreement, the Company and GSK agreed to collaborate to research, develop and 
commercialize products for the prevention, treatment and prophylaxis of diseases caused by SARS-CoV-2, the virus that causes COVID-19, and potentially 
other coronaviruses. The collaboration is focused on the development and commercialization of three types of collaboration products under three programs: 
(1) antibodies targeting SARS-CoV-2, and potentially other coronaviruses (the “Antibody Program”); (2) vaccines targeting SARS-CoV-2, and potentially 
other coronaviruses (the “Vaccine Program”), and (3) products based on genome-wide CRISPR screening of host targets expressed in connection with 
exposure to SARS-CoV-2, and potentially other coronaviruses (the “Functional Genomics Program”). 

For four years following the Effective Date, the parties agreed to conduct certain research and development activities under mutually agreed 
development plans and associated budgets for each of the three programs, and under the oversight of a joint steering committee (“JSC”). The Company is 
primarily responsible for the development and clinical manufacturing activities for the Antibody Program, and for conducting the initial development 
activities directed to a vaccine in the Vaccine Program. GSK is primarily responsible for the commercialization activities for the Antibody Program (except 
in connection with sales of antibody products licensed to WuXi Biologics (Hong Kong) Limited in greater China), the later-stage development, 
manufacturing and commercialization activities for the Vaccine Program and the development, manufacturing and commercialization activities for the 
Functional Genomics Program. Subject to an opt-out mechanism, the parties share all development costs, manufacturing costs and costs and expenses for 
the commercialization of the collaboration products, with the Company bearing 72.5% of such costs for the antibody products, 27.5% of such costs for the 
vaccine products, and equal sharing of such costs for the functional genomics products.

On a collaboration product-by-collaboration product basis, each party has the one-time right, at specified points in development, to opt-out of its co-
funding obligations, and the other party may, at its election, either pursue such program unilaterally, or also cease research and development activities and 
funding of such collaboration product. If the opt-out provisions are not exercised by either party subject to the terms of the 2020 GSK Agreement, the 
parties share all profits and losses arising from any collaboration product in the same ratios in which the parties bore development costs for such 
collaboration program. For each collaboration product as to which a party exercises its opt-out right, the commercializing party pays to the opt-out party 
royalties on net sales of the applicable collaboration product at rates based on factors such as the stage of development of such collaboration product at the 
time the opt-out party exercises such right, and whether the opt-out party is the lead party, or a portion of the sublicense revenue if the commercializing 
party chooses to sublicense or otherwise divest rights to such collaboration product. On an antibody product-by-antibody product basis, the Company has a 

159

 
VIR BIOTECHNOLOGY, INC.

Notes to Consolidated Financial Statements 

co-promotion right for such antibody product in the United States, under which the Company has the right to perform up to 20% of details in connection 
with such antibody product. 

The 2020 GSK Agreement will remain in effect with respect to each collaboration program for as long as there is a collaboration product being 

developed or commercialized by the lead party, or the non-opt-out party, in such program. Either party has the right to terminate the 2020 GSK Agreement 
in the case of the insolvency of the other party, an uncured material breach of the other party with respect to a collaboration program or collaboration 
product, or as mutually agreed by the parties. The 2020 GSK Agreement superseded and replaced the 2020 Preliminary Agreement between the parties. In 
December 2021, Beecham S.A. assigned and transferred all its rights, title, interest, and benefit in the 2020 GSK Agreement to GlaxoSmithKline 
Biologicals S.A., including all its rights to bring claims under such agreement.

The Company considered the ASC 606 criteria for combining contracts and determined that the 2020 GSK Agreement and 2020 Stock Purchase 

Agreement should be combined into a single contract because they were negotiated and entered into in contemplation of one another. The fair market value 
of the common stock issued to GGL was $206.7 million, based on the closing stock price of $36.70 on the date of execution of the 2020 Preliminary 
Agreement and 2020 Stock Purchase Agreement and taking into account a discount for the lack of marketability due to the restrictions in place on the 
underlying shares, resulting in a $43.3 million premium received by the Company. The Company accounted for the common stock issued to GGL based on 
its fair market value on the transaction date and determined that the premium paid by GSK should be attributed to the transaction price of the 2020 GSK 
Agreement. 

The Company concluded that the 2020 GSK Agreement contained four units of account: (i) the license granted to GSK under the Antibody Program 
(the “Antibody License”); (ii) the research and development activities (including clinical manufacturing) under the Antibody Program; (iii) the research and 
development activities under the Vaccine Program; and (iv) the research and development activities under the Functional Genomics Program. The 
Company considered the guidance in ASC 606 to determine which of these elements of the 2020 GSK Agreement are performance obligations with a 
customer. The Company determined that the Antibody License is within the scope of ASC 606 and accordingly, accounted for the Antibody License as a 
distinct performance obligation under ASC 606. The Antibody License is a functional intellectual property and is distinct from the associated research and 
development activities to be performed under the program due to its significant standalone functionality. All other elements of the 2020 GSK Agreement 
including the research and development activities, and participation in the JSC and subcommittees for each collaboration program were not determined to 
be distinct performance obligations with a customer. 

The transaction price for the Antibody License at inception was determined to be $43.3 million, representing the premium on the sale of common 

stock to GSK. The Company determined that GSK can benefit from the Antibody License at the time of grant and therefore, the related performance 
obligation is satisfied at a point in time. As such, the Company recognized the $43.3 million as contract revenue during the second quarter of 2020. 
Additionally, the Company is entitled to consideration from GSK related to profit and loss sharing arrangements (including royalties) contingent upon 
future sales of collaboration products under the Antibody Program. 

The remaining units of account of the 2020 GSK Agreement were determined to be within the scope of ASC 808 as the Company and GSK are both 
active participants in the development, manufacturing and commercialization activities and are exposed to significant risks and rewards that are dependent 
on the commercial success of the activities of the arrangement. Furthermore, the Company and GSK participate in the commercial profit and loss sharing 
arrangement for each program commensurate with each party’s cost-sharing responsibilities during research and development. Because ASC 808 does not 
provide recognition and measurement guidance, the Company determined that the guidance in ASC 730, Research and Development, was appropriate to 
analogize to, based on the nature of the cost-sharing provisions of the agreement. The Company has concluded that payments to or reimbursements from 
GSK related to these services will be accounted for as an increase to or reduction of research and development expenses, respectively. The Company also 
concluded that any payments from GSK related to the profit and loss sharing arrangement (including royalties) contingent upon the commercialization of 
the products under the Vaccine and Functional Genomics Programs will be analogized to ASC 606 and therefore, will be recognized when the related sales 
occur.

In May 2021, the FDA granted an EUA in the United States for sotrovimab, the first collaboration product under the Antibody Program. As the lead 
party for all commercialization activities, GSK incurs all of the sales and marketing expenses and is the principal on sales transactions with third parties. As 
the Company is the agent under the 2020 GSK Agreement, the Company recognizes its contractual share of the profit-sharing amounts or royalties (in case 
of an opt-out) as revenue, net of 

160

Notes to Consolidated Financial Statements 

any cost of sales and allowable expenses (including distribution, selling, and marketing expenses) in the period the sale occurs. During the year ended 
December 31, 2021, the Company recorded its share of net profit of $917.2 million as collaboration revenue in the consolidated statement of operations. 

Costs associated with co-development activities performed under the agreement are included in research and development expenses on the 

consolidated statements of operations, with any reimbursement of costs by GSK reflected as a reduction of such expenses. Under the 2020 GSK 
Agreement, the Company recognized additional net research and development expenses of $77.3 million and $25.4 million during the years ended 
December 31, 2021 and 2020, respectively. 

2021 Expanded GSK Collaboration

On February 14, 2021, the Company and GSK entered into a binding preliminary collaboration agreement (the “2021 Preliminary Agreement”), 

under which the parties agreed to expand the 2020 GSK Agreement to collaborate on three separate programs: (1) a program to research, develop and 
commercialize mAbs for the prevention, treatment or prophylaxis of the influenza virus (the “Influenza Program”), excluding VIR-2482 unless GSK 
exercises its option as described below; (2) an expansion of the parties’ current Functional Genomics Program to focus on functional genomics screens 
directed to targets associated with respiratory viruses (the “Expanded Functional Genomics Program”); and (3) additional programs to develop neutralizing 
mAbs directed to up to three non-influenza target pathogens selected by GSK (the “Selected Pathogens” and such programs, the “Additional Programs”). 

Concurrently with the execution of the 2021 Preliminary Agreement, the Company entered into a stock purchase agreement (the “2021 Stock 

Purchase Agreement”) with GGL under which GGL agreed to purchase shares of the Company’s common stock for an aggregate purchase price of 
approximately $120.0 million. The consummation of the transactions under each of the 2021 Preliminary Agreement and the 2021 Stock Purchase 
Agreement were subject to the satisfaction of customary closing conditions, including the expiration or termination of the applicable waiting period under 
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, which expiration was effective on March 24, 2021. The 2021 Preliminary 
Agreement and 2021 Stock Purchase Agreement consummated on March 25, 2021, which the Company used as the measurement date for accounting 
purposes. On March 31, 2021, the Company closed the sale of 1,924,927 shares of its common stock to GGL. 

The 2021 Preliminary Agreement was superseded on May 18, 2021 upon execution of the definitive collaboration agreement (the “2021 GSK 
Agreement”, or collectively with the 2021 Preliminary Agreement, the “2021 GSK Collaboration”). The material terms of the 2021 GSK Agreement, 
including the promised goods and services, are discussed below and is consistent with those of the 2021 Preliminary Agreement. 

Under the 2021 GSK Collaboration, the parties will conduct certain research and development activities under mutually agreed development plans 

and associated budgets for the programs within the expanded collaboration for a period of three years following the effective date. Under the Influenza 
Program, the parties will collaborate to research, develop and commercialize mAbs for the prevention, treatment or prophylaxis of influenza, including the 
Company’s influenza mAbs (with respect to VIR-2482, only if GSK exercises its option). The Company may conduct the development and clinical 
manufacturing activities for VIR-2482 up to the completion of a Phase 2 clinical trial. Provided that the Company conducts and completes a Phase 2 
clinical trial for VIR-2482, GSK will have the exclusive option to obtain exclusive rights to co-develop and commercialize VIR-2482 under the Influenza 
Program (the “VIR-2482 Option”). GSK will be the lead party for development, clinical and commercial manufacturing and commercialization activities 
for products under the Influenza Program (other than VIR-2482 unless and until GSK exercises the VIR-2482 Option, if applicable). The parties will 
mutually agree upon the allocation of responsibility for the development of products under the Expanded Functional Genomics Program, and for the 
development and early-stage manufacturing of products under the Additional Programs if and when GSK decides which Selected Pathogens to pursue. 
GSK will be primarily responsible for commercial manufacturing and commercialization activities for products under the Expanded Functional Genomics 
Program and Additional Programs, if and when selected by GSK. For each collaboration program, upon execution of the definitive agreement, the 
Company will grant GSK certain license rights related to the development, manufacturing and commercialization of products arising from the program.

The parties will share 50% of all development costs in accordance with the budget for each of the collaboration programs (other than for the 
Selected Pathogens and VIR-2482, unless GSK exercises the VIR-2482 Option), with each party having the right to opt-out of its co-funding obligations at 
specified points in development. In such case, the party continuing 

161

 
VIR BIOTECHNOLOGY, INC.

Notes to Consolidated Financial Statements 

with the program will pay to the opt-out party a royalty on net sales of products arising from such program at specified rates based on the stage of 
development at which the opt-out is exercised. Following the exercise of an opt-out right by a party, the other party may, at its election, either pursue 
development and commercialization of such product or program unilaterally, or also cease the conduct and funding of such collaboration product or 
program. In the absence of any opt-out, the parties will also share 50% of all profits and losses arising from any collaboration product. 

GSK was obligated to make an upfront payment to the Company of $225.0 million, 50% of which became payable at the effective date of the 2021 
Preliminary Agreement and 50% of which became payable following the execution of the 2021 GSK Agreement. If GSK exercises the VIR-2482 Option, 
GSK will pay the Company an option exercise fee of $300.0 million unless certain agreed product criteria for VIR-2482 are not met, in which case the 
parties will negotiate an alternative option exercise fee. Upon achievement of a pre-defined regulatory milestone for the first product in the Influenza 
Program, which may be (i) VIR-2482 (if GSK exercised the VIR-2482 Option), (ii) a next-generation mAb, or (iii) any other influenza mAb approved by 
the JSC to be included in the collaboration, arising from the Influenza Program, GSK will make a milestone payment to the Company of up to $200.0 
million. 

The Company concluded that the 2021 GSK Agreement is a collaboration arrangement as defined in ASC 808, Collaborative Agreements, under 

which certain elements are required to be accounted for under ASC 606 where the counterparty is a customer for a good or service that is a distinct unit of 
account. In addition, the 2021 GSK Agreement is considered a contract modification to the 2021 Preliminary Agreement and will be accounted for 
prospectively, as a termination of the 2021 Preliminary Agreement and commencement of a new contract. There was no impact to the accounting 
assessment of the original contract as no goods or services had been delivered to GSK, no performance obligations were satisfied, and accordingly, no 
contract revenue was recognized under ASC 606 prior to the execution of the 2021 GSK Agreement.

The Company considered the ASC 606 criteria for combining contracts and determined that the 2021 GSK Collaboration and 2021 Stock Purchase 
Agreement should be combined into a single contract because they were negotiated and entered into in contemplation of one another. The fair market value 
of the common stock issued to GGL was $85.2 million, based on the closing stock price of $52.70 on March 25, 2021 and taking into account a discount 
for the lack of marketability due to the restrictions in place on the underlying shares, resulting in a $34.8 million premium received by the Company. The 
Company accounted for the common stock issued to GGL based on its fair market value on the transaction date and determined that the premium paid by 
GSK should be attributed to the transaction price of the 2021 GSK Agreement.

The Company concluded that the 2021 GSK Agreement contained the following units of account: (i) the VIR-2482 Option; (ii) three distinct rights 
granted to GSK related to the Selected Pathogens (each, a “Selected Pathogens Right”); (iii) the license and know-how to the next-generation mAbs under 
the Influenza Program (the “Next Gen License”); (iv) the research and development activities for next-generation mAbs under the Influenza Program; and 
(v) the research and development activities, including license rights and know-how, under the Expanded Functional Genomics Program. The Company 
considered the guidance in ASC 606 to determine which of these elements of the 2021 GSK Agreement are performance obligations with a customer. The 
Company determined that the distinct performance obligations under ASC 606 consisted of (i) the Next Gen License and (ii) the three Selected Pathogens 
Rights, each representing a material right. All other elements of the 2021 GSK Agreement including the VIR-2482 Option, research and development 
activities, and participation in the JSC and subcommittees for each collaboration program were not determined to be distinct performance obligations with a 
customer. As of December 31, 2021, GSK had not exercised the VIR-2482 Option.  

The transaction price for the 2021 GSK Agreement included fixed consideration consisting of the $225.0 million upfront fee paid by GSK and $34.8 

million, representing the premium on the sale of common stock to GSK for a total of $259.8 million. All potential future milestones and other payments 
under the 2021 GSK Agreement are constrained since the Company could not conclude it was probable that a significant reversal in the amount recognized 
would not occur.

The respective estimated SSP for each of the performance obligations was determined to allocate the transaction price. The estimated SSP of each 

performance obligation was determined using methods that considered relevant market conditions, entity-specific factors and information about GSK, 
while maximizing the use of available observable inputs and using certain management assumptions (e.g., treatable patient population, expected market 
share, probability of success and product profitability, discount rate based on weighted-average cost of capital). For the Next Gen License, the Company 
determined that GSK can benefit from the license at the time the license is granted, and therefore, the related performance obligation is satisfied at a point 
in time. If any of the Selected Pathogens Rights are exercised, the Company will evaluate the 

162

 
VIR BIOTECHNOLOGY, INC.

Notes to Consolidated Financial Statements 

related promises to identify the performance obligations to be transferred and the timing of revenue recognition. If any of the Selected Pathogens Rights 
expire prior to being exercised, the Company will recognize any deferred revenue allocated to that right as revenue at the time of expiration. 

The research and development activities for the next generation mAbs under the Influenza Program and the Expanded Functional Genomics 
Program were determined to be within the scope of ASC 808 as the Company and GSK are both active participants in the development, manufacturing and 
commercialization activities and are exposed to significant risks and rewards that are dependent on the commercial success of the activities of the 
arrangement. Furthermore, the Company and GSK participate in the commercial profit and loss sharing arrangement for each program commensurate with 
each party’s cost-sharing responsibilities during research and development. Because ASC 808 does not provide recognition and measurement guidance, the 
Company determined that the guidance in ASC 730, Research and Development, was appropriate to analogize to based on the nature of the cost-sharing 
provisions of the agreement. The Company has concluded that payments to or reimbursements from GSK related to these services will be accounted for as 
an increase to or reduction of research and development expenses, respectively. The Company also concluded that any payments from GSK related to the 
profit and loss sharing arrangement (including royalties) contingent upon the commercialization of the related products will be analogized to ASC 606 and 
therefore, will be recognized when the related sales occur.

Upon execution of the 2021 GSK Agreement, the Company granted the Next Gen License to GSK and therefore, recognized $168.3 million as 

contract revenue in the second quarter of 2021. As of December 31, 2021, the total unrecognized transaction price of $91.5 million is classified as current 
deferred revenue on the Company's consolidated balance sheet related to the remaining performance obligations, being the material rights resulting from 
the Selected Pathogens Rights, none of which have been exercised by GSK as of December 31, 2021. The Company expects the rights will be exercised, 
and thus, the corresponding deferred revenue will be recognized within the next 12 months from the balance sheet date. 

Costs associated with co-development activities performed under the agreement are included in research and development expenses in the 

consolidated statements of operations, with any reimbursement of costs by GSK reflected as a reduction of such expenses. During the year ended December 
31, 2021, the Company recognized additional net research and development expense of $0.5 million under the 2021 GSK Agreement. 

Under both the 2020 GSK Agreement and the 2021 GSK Agreement, the Company has a receivable from collaboration of $773.1 million as of 

December 31, 2021. 

Brii Biosciences 

In May 2018, the Company entered into the Brii Agreement with Brii Bio Parent and Brii Bio pursuant to which the Company granted to Brii Bio, 

with respect to up to four of the Company’s programs, an exclusive option to obtain exclusive rights to develop and commercialize compounds and 
products arising from such programs in China, Taiwan, Hong Kong and Macau (collectively, the “China Territory”) for the treatment, palliation, diagnosis, 
prevention or cure of acute and chronic diseases of infectious pathogen origin or hosted by pathogen infection (the “Field of Use”). The Company’s HBV 
small interfering ribonucleic acid (“siRNA”) program being developed under the Amended Alnylam Agreement (described below) is included within the 
Brii Agreement as a program for which Brii Bio may exercise one of its options. In partial consideration for the options granted by the Company to Brii 
Bio, Brii Bio Parent and Brii Bio granted the Company, with respect to up to four of Brii Bio Parent’s or Brii Bio’s programs, an exclusive option to be 
granted exclusive rights to develop and commercialize compounds and products arising from such Brii Bio programs in the United States for the Field of 
Use. The number of options that the Company may exercise for a Brii Bio program is limited to the corresponding number of options that Brii Bio 
exercises for a Vir program. 

As partial consideration for the Company’s entry into the Brii Agreement, upon closing of Brii Bio Parent’s Series A preferred stock financing, the 
Company received ordinary shares equal to 9.9% of the outstanding shares in Brii Bio Parent. As a result of Brii Bio’s right to exercise one of its options 
for the Company’s HBV siRNA program, under the terms of the Amended Alnylam Agreement, the Company transferred to Alnylam Pharmaceuticals, Inc. 
("Alnylam") a specified percentage of such equity consideration allocable to such program under a share transfer agreement in February 2020. 

With respect to programs for which Brii Bio exercises its options, Brii Bio will be required to pay the Company an option exercise fee for each such 

Vir program ranging from the mid-single-digit millions up to $20.0 million, determined 

163

 
VIR BIOTECHNOLOGY, INC.

Notes to Consolidated Financial Statements 

based on the commercial potential of the licensed program. Brii Bio will also be required to pay regulatory milestone payments on a licensed product-by-
licensed product basis ranging from the mid-single-digit millions up to $30.0 million, also determined based on the commercial potential of such program. 
Following commercialization, Brii Bio will be required to make sales milestone payments based on certain specified levels of aggregate annual net sales of 
products arising from each licensed program in the China Territory, up to an aggregate of $175.0 million per licensed program. Brii Bio also will pay 
royalties to the Company that range from the mid-teens to the high-twenties, as described below. 

Upon exercise of each option for a Brii Bio program, the Company will be required to pay to Brii Bio an option exercise fee ranging from the low 

tens of millions to up to $50.0 million, determined based on the commercial potential of the licensed program. The Company will be required to make 
regulatory milestone payments to Brii Bio on a licensed product-by-licensed product basis ranging from the low tens of millions up to $100.0 million, also 
determined based on the commercial potential of such program. The Company will also be required to make sales milestone payments based on certain 
specified levels of aggregate annual net sales of products in the United States arising from each licensed program, up to an aggregate of $175.0 million per 
licensed program. 

In addition, the Company is obligated under the Brii Agreement to pay Brii Bio tiered royalties based on net sales of products arising from the 

licensed programs in the United States, and Brii Bio is obligated to pay the Company tiered royalties based on net sales of products arising from the 
licensed programs in the China Territory. The rates of royalties payable by the Company to Brii Bio, and by Brii Bio to the Company, on net sales range 
from mid-teens to high-twenties. Each party’s obligations to pay royalties expires, on a product-by-product and territory-by-territory basis, on the latest of 
10 years after the first commercial sale of such licensed product in the United States or China Territory, as applicable; the expiration or abandonment of 
licensed patent rights that cover such product in the United States or China Territory, as applicable; and the expiration of regulatory exclusivity in the 
United States or the China Territory, as applicable. Royalty rates are subject to specified reductions and offsets. 

The Brii Agreement will remain in force until the expiration of all options or, if any option is exercised, expiration of all royalty payment obligations 

for all licensed products within such licensed program, unless terminated in its entirety or on a program-by-program basis by either party. Each party may 
terminate for convenience all rights and obligations with respect to any program for which it has an option, with 30 days’ written notice (if the terminating 
party has not exercised an option for such program) or 180 days’ notice (following the exercise of an option for such program). The Brii Agreement may 
also be terminated by either party for insolvency of the other party, and either party may terminate the Brii Agreement in its entirety or on a program-by-
program basis for the other party’s uncured material breach on 60 days’ written notice (or 30 days’ notice following failure to make payment). 

From May 2018 until July 2021, the Brii Bio Parent IPO closing date, Brii Bio Parent and its wholly-owned subsidiary Brii Bio were determined to 
be variable interest entities ("VIE") due to their reliance on future financing and having insufficient equity at risk. However, the Company did not have the 
power to direct activities that most significantly impact the economic success of these entities and was not considered the primary beneficiary of these 
entities. Therefore, the Company did not consolidate Brii Bio Parent or Brii Bio. Subsequent to the Brii Bio Parent IPO, the Company determined that these 
entities are no longer VIEs. In addition, as Brii Bio Parent is a publicly-traded company, the Company's investment in its ordinary shares became a 
marketable equity investment with readily determinable fair value and is then subsequently remeasured to fair value at each reporting date (see Note 3—
Fair Value Measurements). Prior to the Brii Bio Parent IPO, the Company accounted for its investment in Brii Bio Parent, which had a carrying value of 
$5.7 million, at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar 
investment from the same issuer. 

Under the Brii Agreement, the Company also has a contract liability of $3.8 million within noncurrent deferred revenue which represents deferred 

consideration for the remaining three options that the Company granted to Brii Bio. The deferred consideration will be recognized when Brii Bio exercises 
its options or the options expire. 

Option Exercise by Brii Bio

In June 2020, Brii Bio exercised its option to obtain exclusive rights to develop and commercialize compounds and products arising from VIR-2218 
in the China Territory. In consideration of the Company’s grant to Brii Bio of an exclusive license related to VIR-2218 in the China Territory, the Company 
received a $20.0 million option exercise fee in connection with the option exercise. Also, the Company is eligible to receive the following payments related 
to VIR-2218 in the China 

164

 
 
 
VIR BIOTECHNOLOGY, INC.

Notes to Consolidated Financial Statements 

Territory: a $30.0 million regulatory milestone payment, up to $175.0 million in sales-based milestone payments, and royalties on net sales ranging from 
high-teens to high-twenties. 

The Company evaluated the transaction under ASC 606 and identified one performance obligation consisting of the license granted to Brii Bio. 

Under the Brii Agreement, Brii Bio is responsible for performing all research and development activities and the Company does not have any other 
performance obligations within the context of ASC 606 under the arrangement after the option exercise. The transaction price is determined to be $22.7 
million which consists of the $20.0 million option exercise fee and $2.7 million of the deferred revenue allocated to the VIR-2218 option at the inception of 
the Brii Agreement. The Company determined that the license is considered a functional intellectual property that is a distinct performance obligation under 
ASC 606. Specifically, the Company believes the license is capable of being distinct, as Brii Bio has the capabilities to develop the license either on its own 
or by contracting other third parties. Brii Bio can benefit from the license at the time of grant and therefore, the related performance obligation is satisfied 
at a point in time. Additionally, all potential future milestones and other payments are constrained because the Company cannot conclude it is probable that 
a significant reversal in the amount recognized would not occur. The Company will re-evaluate the transaction price in each reporting period. 

During the years ended December 31, 2021 and 2020, the Company recognized $0.4 million and zero, respectively, as contract revenue from the 

supply of biological materials to Brii Bio. During the years ended December 31, 2021 and 2020, the Company recognized zero and $22.7 million as license 
revenue from a related party. The Company separately paid $10.0 million, half of the option exercise proceeds, to Alnylam in connection with the 
Amended Alnylam Agreement that was recognized as research and development expense during the second quarter of 2020.

Alnylam 

October 2017 Agreement

In October 2017, the Company entered into the collaboration and license agreement with Alnylam (the “Alnylam Agreement”) for the development 

of siRNA products for the treatment of HBV and following the exercise of certain program options, the development and commercialization of siRNA 
products directed to up to four other infectious disease targets selected by the Company. The technology licensed under the Alnylam Agreement forms the 
basis of the Company’s siRNA technology platform. 

Under the Alnylam Agreement, the Company obtained a worldwide, exclusive license to develop, manufacture and commercialize the HBV siRNA 

product candidates, including VIR-2218, for all uses and purposes other than agricultural, horticultural, forestry, aquaculture and other residential 
applications, such excluded fields, the Excluded Fields. In addition, Alnylam granted the Company an exclusive option, for each of the infectious disease 
siRNA programs directed to the Company’s selected targets, to obtain a worldwide, exclusive license to develop, manufacture and commercialize siRNA 
products directed to the target of each such program for all uses and purposes other than the Excluded Fields. On a product-by-product basis for each 
product arising from the HBV and, following the Company’s option exercise, the infectious disease programs, Alnylam has an exclusive option, 
exercisable during a specified period prior to the initiation of a Phase 3 clinical trial for each such product, to negotiate and enter into a profit-sharing 
agreement for such product.

The Company and Alnylam are jointly responsible for funding the initial research and development activities for VIR-2218 through the completion 

of proof of concept trials. Prior to the exercise of the Company’s option for each siRNA program directed to one of the Company’s selected infectious 
disease targets, Alnylam is responsible for conducting all development activities, at the Company’s expense, in accordance with an agreed-upon 
development plan. Following the Company’s exercise of an option for a program and payment of the program option exercise fee and any outstanding 
program costs due to Alnylam, the Company is solely responsible, at the Company’s expense (subject to Alnylam’s exercise of a profit-sharing option), for 
conducting all development, manufacture and commercialization activities for products arising from each such program. If Alnylam exercises a profit-
sharing option for a product, the Company will negotiate the terms of such profit-sharing agreement, which will include sharing equally with Alnylam all 
subsequent costs associated with the development of such product, as well as the profits and losses in connection with such product, subject to 
reimbursement by Alnylam of a portion of specified development costs in certain circumstances. 

165

 
VIR BIOTECHNOLOGY, INC.

Notes to Consolidated Financial Statements 

Under the Alnylam Agreement, the Company paid Alnylam an upfront fee of $10.0 million and issued to Alnylam 1,111,111 shares of the 
Company’s common stock. Additionally, the receipt of consideration from Brii Bio as discussed above triggered a requirement under the Alnylam 
Agreement to transfer a portion of the consideration, consisting of equity in Brii Bio Parent valued at $0.8 million, to Alnylam.

Upon the achievement of a certain development milestone, as further discussed below, the Company was obligated to issue shares of the Company’s 
common stock equal to the lesser of (i) 1,111,111 shares or (ii) a certain number of shares based on the Company’s stock price at the time such milestone is 
achieved (the “Milestone Shares”). The Company will be required to pay Alnylam up to $190.0 million in the aggregate for the achievement of specified 
development and regulatory milestones by the first siRNA product directed to HBV, and up to $115.0 million for the achievement of specified development 
and regulatory milestones by the first product directed to the target of each infectious disease siRNA program for which the Company exercised its option. 
Following commercialization, the Company will be required to pay to Alnylam up to $250.0 million in the aggregate for the achievement of specified 
levels of net sales by siRNA products directed to HBV and up to $100.0 million for the achievement of specified levels of net sales by products directed to 
the target of each infectious disease siRNA program for which the Company exercised its option. The Company may also be required to pay Alnylam 
tiered royalties at percentages ranging from the low double-digits to mid-teens on annual net sales of HBV products, and tiered royalties at percentages 
ranging from the high single-digits to the sub-teen double-digits on annual net sales of licensed infectious disease products, in each case subject to specified 
reductions and offsets. The royalties are payable on a product-by-product and country-by-country basis until the later of the expiration of all valid claims of 
specified patents covering such product in such country and 10 years after the first commercial sale of such product in such country. 

The term of the Alnylam Agreement will continue, on a product-by-product and country-by-country basis, until the expiration of all royalty payment 

obligations under the Alnylam Agreement. If the Company does not exercise its option for an infectious disease program directed to one of its selected 
targets, the Alnylam Agreement will expire upon the expiration of the applicable option period with respect to such program. However, if Alnylam 
exercises its profit-sharing option for any product, the term of the Alnylam Agreement will continue until the expiration of the profit-sharing arrangement 
for such product. The Company may terminate the Alnylam Agreement on a program-by-program basis or in its entirety for any reason on 90 days’ written 
notice. Either party may terminate the agreement for cause for the other party’s uncured material breach on 60 days’ written notice (or 30 days’ notice for 
payment breach), or if the other party challenges the validity or enforceability of any patent licensed to it under the Alnylam Agreement on 30 days’ notice.

In March 2020, the Company achieved the specified development milestone relating to the Milestone Shares, which was accounted for as an 
embedded derivative. Consequently, the Company remeasured and reclassified the derivative liability to additional paid-in capital based on the estimated 
fair value of $29.2 million. The Company issued Alnylam 1,111,111 shares of its common stock and paid Alnylam $15.0 million in the second quarter of 
2020.

Second and Third Amendments 

In March and April 2020, the Company and Alnylam entered into the second and third amendments to the Alnylam Agreement (as amended, the 

“Amended Alnylam Agreement”) to expand the parties’ existing collaboration to include the development and commercialization of siRNA products 
targeting SARS-CoV-2, and potentially other related coronaviruses, and up to three targeting human host factors for SARS-CoV-2 (collectively, the 
“COVID Collaboration Targets”).

In December 2020, the Company and Alnylam entered into a letter amendment (the “Letter Agreement”), further amending the Amended Alnylam 

Agreement, to modify certain funding and governance provisions in connection with the siRNA products directed to the COVID Collaboration Targets, 
including VIR-2703 (the “COV Target”), and to modify certain rights of each party with respect to products arising from such programs. Pursuant to the 
Letter Agreement, Alnylam was responsible for conducting pre-clinical research activities set forth in the existing workplan for the COV Target (the “COV 
Workplan”) at its discretion and sole expense, and the Company was no longer obligated to reimburse Alnylam for any share of costs incurred by Alnylam 
in conducting activities under the COV Workplan after July 1, 2020. In July 2021, Alnylam elected to discontinue the development of the COV Target, and 
all other related research and development activities in accordance with their rights under the Letter Agreement. As a result, the COV Target and the siRNA 
program related thereto are no longer included within the Amended Alnylam Agreement and all rights to the siRNA program directed to the COV Target 
reverted to Alnylam.

Commitments and Contingencies 

Lease Agreements

The Company has various operating lease arrangements for office and laboratory spaces located in California, Oregon, Missouri, and Switzerland 

with contractual lease periods expiring between 2022 and 2033. These leases require monthly lease payments that may be subject to annual increases 
throughout the lease term. Certain lease agreements also provide the Company with the option to renew for additional periods ranging from one to five 
years. These renewal options are not considered in the remaining lease term unless it is reasonably certain that the Company will exercise such options. 

In October 2021, the Company entered into a new sublease agreement for office and laboratory spaces in Missouri that will expire in December 
2028, with no option to renew. Under this sublease arrangement, the Company is entitled to tenant improvement allowance of up to $14.7 million related to 
the design and construction of certain Company improvements.

Notes to Consolidated Financial Statements 

In December 2021, the Company entered into a lease agreement with the new owner of the building at 1800 Owens Street in San Francisco for the 
lease of approximately 133,896 rentable square feet of office and laboratory space of such building. The Company previously occupied the same premises 
under a sublease agreement with a sublessor, which sublease was terminated concurrently with the execution of the new lease agreement. Accordingly, the 
related ROU asset and lease liability under the sublease arrangement were extinguished and the Company recognized a gain of $4.8 million in the 
consolidated statement of operations for the year ended December 31, 2021. The new lease will expire in December 2033, with no option to renew. Under 
this lease arrangement, the Company is entitled to tenant improvement allowance of up to $37.5 million related to the design and construction of certain 
Company improvements.    

Under two of the operating lease arrangements in California and Missouri discussed above, the Company expects to fully utilize the tenant 

improvement allowance, and therefore, such amount is treated as a lease incentive that is payable to the Company at the lease commencement date. 

Throughout the term of the lease agreements, the Company is responsible for paying certain operating costs, in addition to rent, such as common 

area maintenance, taxes, utilities and insurance. These additional charges are considered variable lease costs and are recognized in the period in which the 
costs are incurred.

under each of the WuXi Biologics MSA and Samsung MSA, and GSK will bear 27.5% of such costs under each of the Samsung MSA and the WuXi 
Biologics MSA, subject to certain conditions and exceptions.

Indemnification 

In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Under such agreements, the 

Company may indemnify, hold harmless and defend an indemnified party for losses suffered or incurred by the indemnified party. In some cases, the 
indemnification will continue after the termination of the agreement. The maximum potential amount of future payments the Company could be required to 
make under these provisions is not determinable. In addition, the Company has entered into indemnification agreements with its directors and certain 
officers that may require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service 
as directors or officers. To date, no demands have been made upon the Company to provide indemnification under these agreements, and thus, there are no 
indemnification claims that the Company is aware of that could have a material effect on the Company’s consolidated balance sheets, consolidated 
statements of operations, or consolidated statements of cash flows.

Related Party Transactions 

As a result of the Brii Agreement in May 2018, the Company holds a minority equity interest in Brii Bio through its parent company, Brii Bio 
Parent. At the time when the Company entered into the Brii Agreement, the Company's Chief Executive Officer, or CEO, and another member of the 
Company's board of directors served on Brii Bio Parent’s board of directors. The Company's CEO, who is also a member of the Company's board of 
directors, resigned from Brii Bio Parent’s board of directors in June 2021. As of December 31, 2021, one member of the Company’s board of directors still

Convertible Preferred Stock 

Prior to the IPO, under the Company’s amended and restated certificate of incorporation, the Company was authorized to issue two classes of shares: 

preferred stock and common stock. The preferred stock was issued in series.

In January 2019, under the Amended A&R Series A-1 and B Purchase Agreement, the Company sold an aggregate of 18,202,213 shares of Series B 

convertible preferred stock at $18.00 per share for net proceeds of $327.5 million in two closings. The Company was authorized to sell up to 4,020,009 
additional shares of Series B convertible preferred stock in one or more additional closings. 

Upon closing of the IPO, all of the outstanding convertible preferred stock automatically converted into 88,112,733 shares of common stock. After 

the closing of the IPO, there were no shares of convertible preferred stock outstanding.

Convertible Preferred Stock Warrant Liability 

In September 2016, the Company issued a warrant to purchase an aggregate of 244,444 shares of the Company’s Series A-1 convertible preferred 

stock with an exercise price of $4.50 per share in connection with the termination of a sponsor research agreement. The warrant was fully vested upon the 
issuance date and had an expiration date of September 11, 2026. The warrant was initially accounted for as a liability and was subject to remeasurement at 
each reporting period, with changes in estimated fair value recognized as a component of other income (expense), net. Upon the completion of the IPO in 
October 2019, the warrant automatically converted into a warrant to purchase 244,444 shares of common stock. Therefore, the convertible preferred stock 
warrant liability was reclassified to additional paid-in capital. In May 2020, the holder exercised its warrant in a cashless exercise for which the Company 
issued an aggregate of 211,774 shares of common stock.

2019 Equity Incentive Plan 

In September 2019, the Company’s board of directors adopted, with the approval of its stockholders, the 2019 Equity Incentive Plan (the "2019 

Plan") for the issuance of incentive stock options (“ISO”), non-qualified stock options (“NSO”), stock appreciation rights (“SARs”), restricted stock, other 
stock awards and performance cash awards, to employees, non-employee directors, and consultants. The 2019 Plan became effective concurrent with the 
IPO.

Awards granted under the 2019 Plan expire no later than 10 years from the date of grant. For ISO and NSO, the option price shall not be less than 

100% of the estimated fair value on the date of grant. Options granted typically vest over a four-year period but may be granted with different vesting 
terms. As of December 31, 2021, there are 9,092,936 shares available for the Company to grant under the 2019 Plan. 

2016 Equity Incentive Plan 

In September 2016, the Company adopted the 2016 Equity Incentive Plan (the “2016 Plan”) for the issuance of ISO, NSO, SARs, restricted stock 

and other stock awards, to employees, non-employee directors, and consultants under terms and provisions established by the Company’s board of directors 
and approved by the stockholders. 

Awards granted under the 2016 Plan expire no later than 10 years from the date of grant. For ISO and NSO, the option price shall not be less than 

100% of the estimated fair value on the date of grant. Options granted typically vest over a four-year period but may be granted with different vesting 
terms. 

In conjunction with adopting the 2019 Plan, the Company discontinued the 2016 Plan with respect to the new equity awards.

2019 Employee Stock Purchase Plan

In September 2019, the Company’s board of directors adopted, with the approval of its stockholders, the ESPP. The ESPP became effective on the 

completion of the Company’s IPO. 

The ESPP initially authorized the issuance of 1,280,000 shares of the Company’s common stock under purchase rights granted to its employees or 

employees of any of the Company’s designated affiliates. The number of shares of the Company’s common stock reserved for issuance is subject to an 
automatic increase at each calendar year. Under the ESPP, the Company may specify offerings with durations of not more than 27 months and may specify 
shorter purchase periods within each offering. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount 
through payroll deductions of up to 15% of their earnings, subject to any plan limitations. Unless otherwise determined by the Company’s board of 
directors, employees can purchase shares at 85% of the lower of the fair market value of the Company’s common stock on the first date of an offering or 
the purchase date. During the year ended December 31, 2021, 65,021 shares were issued under the ESPP.

The aggregate intrinsic value of options exercised during the years ended December 31, 2021, 2020 and 2019 was $65.1 million $53.1 million and 

$5.5 million, respectively.

During the years ended December 31, 2021, 2020, and 2019, the estimated weighted-average grant date fair value of the options granted was $47.62, 

$25.49, and $7.83 per share, respectively. 

As of December 31, 2021, the Company expects to recognize the remaining unamortized stock-based compensation expense of $176.4 million 

related to stock options, over an estimated weighted average period of 2.5 years. 

Stock Options Granted to Employees 

The fair value of stock options granted to employees was estimated on the date of grant using the Black-Scholes option- pricing model with the 

following assumptions: 

Expected term of options (in years)
Expected stock price volatility
Risk-free interest rate
Expected dividend yield

2021
5.3 – 6.1

Year Ended December 31,
2020

0.3% – 1.2%
—

2019
5.9 – 6.1
86.5% – 89.4%
1.5% – 2.5%
—

The valuation assumptions for stock options was determined as follows: 

Expected Term—The expected term represents the period that the options granted are expected to be outstanding and is determined using the 
simplified method (based on the mid-point between the vesting date and the end of the contractual term) as the Company has concluded that its 
stock option exercise history does not provide a reasonable basis upon which to estimate expected term. 

Expected Volatility—The expected volatility was determined by examining the historical volatilities for industry peers and using an average of 
historical volatilities of the Company’s industry peers as the Company does not have a sufficient historical trading history for its stock. The 
Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of its stock price becomes 
available.

Risk-Free Interest Rate—The Company based the risk-free interest rate over the expected term of the options based on the constant maturity rate of 
U.S. Treasury securities with similar maturities as of the date of the grant. 

Expected Dividend Rate—The expected dividend is zero as the Company has not paid nor does it anticipate paying any dividends on its profit 
interest units in the foreseeable future.

Employees Stock Purchase Plan

In June 2021, the Company initiated its first offering period under the ESPP. Each offering period is six months, which commences on the grant date 

on or after June 1 and December 1 of each year and ends on the purchase date on or before November 30 and May 31 of each year.  

The fair value of employees' purchase rights under the ESPP was estimated on the date of grant using the Black-Scholes option-pricing model with 

the following assumptions for the year ended December 31, 2021: 

Expected term of ESPP (in years)
Expected stock price volatility
Risk-free interest rate
Expected dividend yield

0.5
76.1% - 144.1%
0.04% - 0.1%
—

The expected term of employees’ purchase rights is equal to the purchase period. The expected volatility was determined based on the Company's 
historical volatility. The risk-free interest rate is based on the constant maturity rate of U.S. Treasury securities with similar maturities as of the date of the 
grant over the expected term of the employees’ purchase rights. The expected dividend is zero as the Company has not paid nor does it anticipate paying 
any dividends on its profit interest units in the foreseeable future. Based on the Black-Scholes option-pricing model, the estimated weighted-average grant 
date fair value of the employees' purchase rights granted for the year ended December 31, 2021 was $19.85 per share.

In January 2017, the Company entered into a restricted stock purchase agreement with an executive officer and a restricted stock purchase 
agreement with a director whereby the executive officer and the director purchased an aggregate of 3,624,355 shares of restricted stock. The consideration 
for the restricted stock was the issuance of promissory notes which were non-recourse in nature and were accounted for as in-substance stock options. In 
August 2019, per the terms of the notes, the Company received $3.3 million as repayment of the outstanding promissory notes and accrued interest. The 
Company reduced the restricted stock liability as the common stock vests, which was fully vested as of December 31, 2020.

Although the Company has taxable income for the year ended December 31, 2021, it has otherwise incurred accumulated tax losses since inception. 

Based on the available objective evidence, the Company cannot conclude it is more likely than not that the net deferred tax assets will be fully realizable. 
Accordingly, the Company has provided a valuation allowance against its net deferred tax assets. For the year ended December 31, 2021, the Company 
recorded a valuation allowance release of $114.2 million, based on the estimated 2021 taxable income. For the years ended December 31, 2020 and 2019, 
the valuation allowance increased by $74.1 million and $42.3 million, respectively. As of December 31, 2021, the Company has net operating loss 
carryforwards of $24.2 million for federal purposes and $126.6 million for state tax purposes. If not utilized, these carryforwards will begin expiring in 
2035 for federal and in 2031 for state tax purposes. The federal net operating losses generated after December 31, 2017, have an infinite carryforward 
period and subject to 80% deduction limitation based upon pre-NOL deduction taxable income. As of December 31, 2021, the Company also has net 
operating loss carryforwards of $5.4 million for Australian tax purposes, which has an infinite carryforward period, and no net operating loss carryforward 
for Swiss tax purposes. 

Under the Tax Reform Act of 1986, the amounts of and benefits from net operating loss carryforwards may be impaired or limited in certain 

circumstances. Events which cause limitations in the amount of net operating losses that the Company may utilize in any one year include, but are not 
limited to, a cumulative ownership change of more than 50% over a three-year period. The Company completed its Section 382 analysis as of December 
31, 2021 and based on this analysis, it does not expect that the annual limitations will significantly impact its ability to utilize its net operating loss or tax 
credit carryforwards prior to expiration.

As of December 31, 2021, the Company has research tax credit carryforwards of $6.0 million and $11.0 million for federal and state tax purposes, 

respectively. If not utilized, the federal carryforward will expire in various amounts beginning in 2036. The California credits can be carried forward 
indefinitely. To the extent they were not utilized, Oregon carryforward began expiring in 2022. 

The Tax Cuts and Jobs Act of 2017 subjects a U.S. shareholder to current tax on global intangible low-taxed income ("GILTI") earned by certain 

foreign subsidiaries. The FASB Staff Q&A, Topic 740 No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an 
accounting policy election to either recognize deferred taxes for temporary differences expected to reverse as GILTI in future years or provide for the tax 
expense related to GILTI in the year the tax is incurred. The Company has elected to recognize the tax on GILTI as a period expense in the period the tax is 
incurred.

Uncertain Tax Positions 

As of December 31, 2021 and 2020, the Company had an unrecognized tax benefit of $7.4 million and $4.9 million, respectively, related to transfer 

pricing and research and development tax credits. No amount of unrecognized tax benefits as of December 31, 2021, if recognized, would reduce the 
Company’s effective tax rate because the benefits would be in the form of net operating loss and tax credit carryforwards, which would attract a full 
valuation allowance. There are no provisions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly 
increase or decrease within 12 months of the reporting date. Because the statute of limitations does not expire until after the net operating loss and credit 
carryforwards are actually used, the statutes are still open on calendar years ending December 31, 2017 forward for federal and state purposes. 

The Company did not recognize any expense for interest and penalties related to uncertain tax positions during 2021, 2020 and 2019, and the 

Company does not have any amounts related to interest and penalties accrued at December 31, 2021. The Company files U.S. federal, state, Switzerland 
and Australia tax returns. The Company’s tax years remain open for all years. As of December 31, 2021, the Company was not under examination by the 
Internal Revenue Service or any state or foreign tax jurisdiction. 

A reconciliation of the beginning and ending amounts of the liability for uncertain tax positions is as follows: 

Gross unrecognized tax benefits at January 1
Addition for tax positions taken in the prior years
Reduction for tax positions taken in the prior years
Addition for tax positions taken in current year
Gross unrecognized tax benefits at December 31

Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any 
controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management 
necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) under 

the Exchange Act). Our internal control over financial reporting is designed under the supervision of our Chief Executive Officer and Chief Financial 
Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external 
purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not 
prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of our internal control over financial reporting based on the framework set forth by the Committee of 

Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control—Integrated Framework (2013 Framework). Based on our 
assessment, we concluded that our internal control over financial reporting was effective as of December 31, 2021.

The effectiveness of our internal control over financial reporting has been audited by Ernst & Young LLP, an independent registered public 
accounting firm, as stated in their attestation report herein, which expresses an unqualified opinion on the effectiveness of our internal control over 
financial reporting as of December 31, 2021. 

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during our fourth fiscal quarter ended December 31, 2021 that 

materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors 
of Vir Biotechnology, Inc. 

Opinion on Internal Control over Financial Reporting

We have audited Vir Biotechnology, Inc.’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal 

Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO 
criteria). In our opinion, Vir Biotechnology, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2021, based on the COSO criteria.

181

 
 
 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 
consolidated balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income 
(loss), convertible preferred stock and stockholders’ equity (deficit) and cash flows for each of the three years in the period ended December 31, 2021, and 
the related notes and our report dated February 28, 2022 expressed an unqualified opinion thereon. 

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the 

effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting. 
Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm 
registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain 

reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. 

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing 
and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered 
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. 

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial 

reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s 
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded 
as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures 
of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance 
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the 
financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree 
of compliance with the policies or procedures may deteriorate.

GRANT AMOUNT AND REPORTING & PAYMENT SCHEDULE

GRANT AMOUNT
The Foundation will pay You up to the total grant amount specified in the Reporting & Payment Schedule below. The Foundation’s Primary 
Contact must approve in writing any Budget cost category change of more than [***].

REPORTING & PAYMENT SCHEDULE
Payments are subject to Your compliance with this Agreement, including Your achievement, and the Foundation’s approval, of any applicable 
targets, milestones, and reporting deliverables required under this Agreement. The Foundation may, in its reasonable discretion, modify 
payment dates or amounts and will notify You of any such changes in writing.

REPORTING
You will submit reports according to the Reporting & Payment Schedule using the Foundation’s templates or forms, which the Foundation will 
make available to You and which may be modified from time to time. For a progress or final report to be considered satisfactory, it must 
demonstrate meaningful progress against the targets or milestones for that investment period. If meaningful progress has not been made, the 
report should explain why not and what adjustments You are making to get back on track. Please notify the Foundation’s Primary Contact if 
You need to add or modify any targets or milestones. The Foundation must approve any such changes in writing. You agree to submit other 
reports the Foundation may reasonably request.

ACCOUNTING FOR PERSONNEL TIME

Grant Funds. Such individuals will keep records (e.g., timesheets) of actual time worked on the Project in increments of sixty minutes or less

reports. You will submit copies of such records to the Foundation upon request.

GRANT AGREEMENT
Investment ID INV-016898

ATTACHMENT B
TERMS & CONDITIONS

This Agreement is subject to the following terms and conditions.

PROJECT SUPPORT

PROJECT DESCRIPTION AND CHARITABLE PURPOSE
The Foundation is awarding You this grant to carry out the project described in the Investment Document (“Project”) in order to further the 
Charitable Purpose. The Foundation, in its discretion, may approve in writing any request by You to make non-material changes to the 
Investment Document.

MANAGEMENT OF FUNDS

USE OF FUNDS
You may not use funds provided under this Agreement (“Grant Funds”) for any purpose other than the Project. You may not use Grant Funds 
to reimburse any expenses You incurred prior to the Start Date. At the Foundation’s request, You will repay any portion of Grant Funds 
and/or Income used or committed in material breach of this Agreement, as determined by the Foundation in its discretion.

INVESTMENT OF FUNDS
You must invest Grant Funds in highly liquid investments with the primary objective of preservation of principal (e.g., interest-bearing bank 
accounts or a registered money market mutual fund) so that the Grant Funds are available for the Project. Together with any progress or final 
reports required under this Agreement, You must report the amount of any currency conversion gains (or losses) and the amount of any 
interest or other income generated by the Grant Funds (collectively, “Income”). Any Income must be used for the Project.

SEGREGATION OF FUNDS
You must maintain Grant Funds in a physically separate bank account or a separate bookkeeping account maintained as part of Your 
financial records and dedicated to the Project.

GLOBAL ACCESS

GLOBAL ACCESS COMMITMENT
You will conduct and manage the Project and the Funded Developments in a manner that ensures Global Access. Your Global Access 
commitments will survive the term of this Agreement. “Funded Developments” means the products, services, processes, technologies, 
materials, software, data, other innovations, and intellectual property resulting from the Project (including modifications, improvements, and 
further developments to Background Technology). “Background Technology” means any and all products, services, processes, technologies, 
materials, software, data, or other innovations, and intellectual property created by You or a third party prior to or outside of the Project used 
as part of the Project. “Global Access” means: (a) the knowledge and information gained from the Project will be promptly and broadly 
disseminated; and (b) the Funded Developments will be made available and accessible at an affordable price (i) to people most in need 
within developing countries, or (ii) in support of the U.S. educational system and public libraries, as applicable to the Project.

CAVD MEETINGS
You agree to participate in the relevant CAVD sponsored meetings or working groups to which Your attendance is requested. You agree to 
present the Project’s most current progress and data, consistent with any restrictions that are necessary to maintain appropriate rights to 
intellectual property.

Page 3 of 7

COLLABORATION
Consistent with the programmatic goals and the charitable intent of the CAVD, there is the expectation and requirement that CAVD grantees 
will communicate and collaborate on a periodic basis with other CAVD grantees pursuing similar overarching objectives. The Foundation will 
continue to provide information regarding other entities with whom collaborations should be considered. These collaborations will include but 
will not be limited to the following elements:

•

•

•

Agreeing to meet (with funds either provided in the grant or directly from the Foundation) both individually and as a group with fellow 
grantees at the call of the Foundation.

Agreeing at all other times to be amenable to communication and prompt sharing of data and other fruits of the research on topics of 
mutual interest (consistent with potential intellectual property issues subject to the implementation of any necessary nondisclosure 
agreements).

Considering complementary collaborative research and development efforts with other investigators that will facilitate removal of 
roadblocks to the solution either jointly or for the collaborating party.

Each future year of funding will be contingent upon Your continuing success in meeting these commitments, as judged solely by the 
Foundation. You may confer with Your Foundation Primary Contact any time if you have questions or concerns about the nature of any 
potential communication or collaboration request.

TIMELY COMMUNICATION
Sharing of new resources, tools and technologies with the general research community should coincide with publication of the discovery. 
However, since You will be working as a part of a larger overarching multi-grant program, it is expected that You will expeditiously disclose,

(a) The Foundation is making the Foundation Investment as a “program-related investment” within the meaning of Section 4944(c) 
of the Code. The Foundation’s primary purpose in making the Foundation Investment is to further significantly the accomplishment of the 
Foundation’s  charitable  purposes,  including  the  relief  of  the  poor,  distressed,  and  underprivileged,  the  advancement  of  science,  and  the 
promotion of health by seeking to (i) address global health challenges that disproportionately impact developing countries, and (ii) increase 
the  access  of  poor  and  distressed  individuals  and  families  in  developing  countries  to  life-saving  and  other  important  vaccines,  drugs,  and 
technologies  that  may  assist  in  the  prevention,  treatment,  and  detection  of  the  Target  Diseases  and  Conditions  (collectively,  the 
“Charitability Requirements”).

(b)  The  Foundation  is  making  the  Foundation  Investment  to  secure  Global  Access  rights  to  new,  low-cost  vaccines  and  drugs 
developed  (in  whole  or  in  part)  through  the  use  of  the  Company’s  Platform  Technology  for  the  Target  Diseases  and  Conditions.  The 
Foundation  believes  the  Platform  Technology  has  potential  application  in  the  Target  Diseases  and  Conditions  and,  therefore,  the  Platform 
Technology (and any improvements and developments thereto), in conjunction with the Global Access Commitments described below, will 
achieve the Charitability Requirements.

(c) Use  of  Funds.  The  Company  used  the  proceeds  from  the  HIV/TB  Investment  solely  (1)  to  further  develop  and  leverage  the 
Company’s  Platform  Technology  to  create  Funded  Developments  that  are  reasonably  expected  to  comprise  or  result  in  affordable  drugs, 
therapeutics,  diagnostics,  prophylactics,  or  other  health  products,  services,  and  interventions  for  the  treatment,  prevention,  and/or 
amelioration of Target Diseases and Conditions for people in Developing Countries in accordance with Global Access and (2) to conduct the 
HIV Vaccine Program and the TB Vaccine Program. At least fifty percent (50%) of the HIV/TB Investment was used to conduct the HIV 
Vaccine Program and the TB Vaccine Program. Specific deliverables and objectives with respect to development of the Platform Technology 
and the performance of the HIV Vaccine Program and TB Vaccine Program are set forth below. The Company will use the proceeds from the 
Antibody Development Investment solely to conduct the Vaccinal Antibody Development Program. For the avoidance of doubt, (i) use by the 
Company of the proceeds from the Foundation Investment for [***] the HIV Vaccine Program, the TB Vaccine Program, and the Vaccinal 
Antibody Development Program or the development of Funded Developments (including allocation of reasonable overhead expenses) shall 
be deemed to be funds used to conduct the HIV Vaccine Program, TB Vaccine Program, Vaccinal Antibody Development Program, and/or 
such Funded Development, as applicable, in compliance with this Section 2(c); and (ii) the Company is [***]. The Company shall not use

any proceeds of the Foundation Investment for the following matters without the Foundation’s approval: (i) a payment of dividends or (ii) 
any redemption of shares.

3. Global Access Commitments 

In  furtherance  of  the  Charitability  Requirements  and  Global  Access,  the Company  agrees  to  the  following  (collectively  “Global 

Access Commitments”):

(a) Development of Platform Technology; Additional Global Health Projects; Reports. 

(i) The Company will use Reasonable Efforts to complete the Platform Technology objectives set forth on Appendix 4 and 
to utilize the Platform Technology in accordance with the terms of this Agreement, including to advance the HIV Vaccine Program through 
the completion of Phase 1 clinical trials on the HIV Vaccine Product and to advance the TB Vaccine Program through the completion of IND-
enabling studies on the TB Product in furtherance of the Foundation’s Charitable Purpose. 

activities outlined in Appendix 3 (unless amended pursuant to Section 3(a)(v) below) to achieve the following objectives: [***]. 

(ii)  The  Company  will  use  Reasonable  Efforts  to  advance  the  Vaccinal  Antibody  Program  including  by  completing  the 

(A) [***].

(B) [***]. 

(C) [***]. 

(D) [***].

(iii)  The  Company  agrees  that  after  completion  of  the  requirements  in  the  preceding  Sections  3(a)(i)  and  3(a)(ii)  (or  at 
such  earlier  time  as  the  Foundation  may  elect),  the  Foundation  may  request  that  the  Company  continue  further  development  of  the  HIV 
Vaccine Product, TB Product, and/or any Vaccinal Antibody Product, including through product launch of a final product as further described 
in Section 3(a)(vi) below.

(iv) In addition to the HIV Vaccine Program, the TB Vaccine Program, and the Vaccinal Antibody Development Program, 
the  Company  may  work  together  with  the  Foundation  on  additional  Global  Health  Projects  based  on  the  Platform  Technology  for  Target 
Diseases and Conditions in accordance with Section 3(a)(v) below, if applicable, and/ or if mutually agreed between the Company and the 
Foundation. 

(v)  If  at  any  time  the  Foundation  and  the  Company  [***]  the  Antibody  Development  Investment  to  achieve  the  Charitability 
Requirements  to  continue  some  or  all  of  the  Vaccinal  Antibody  Development  Program,  the  parties  will  [***]  on  one  or  more  additional 
Global  Health  Projects  with  respect  to  one  or  more  Target  Diseases  and  Conditions  on  which  to  redeploy  any  remaining  funds  from  the 
Antibody Development Investment that will not be spent on the Vaccinal Antibody Development Program (the “Remaining Funds”). The 
parties [***] the Vaccinal Antibody Development Program in part and redeploy a portion of the Remaining Funds to other Global Health 
Projects.  For  the  avoidance  of  doubt,  the  Company  will  continue  the  Vaccinal  Antibody  Development  Program  [***]  and  a  failure  of  the 
work relating to one of malaria or HIV in the Vaccinal Antibody Development Program will not constitute a failure of such program provided 
that the work on the other indication has not failed.

7

(A) Any scope of work relating to a Global Health Project to be funded using Remaining Funds will be designed to be 
completed within [***] after commencement of such scope of work; provided that the Company will continue to perform the activities under 
such  scope  of  work  for  a  reasonable  period  if  the  actual  time  taken  extends  beyond  such  [***]  period  and  provided  that  there  are  still 
Remaining Funds available, for up to a maximum of an additional [***] (or such longer period as the Parties may agree in writing).

(B) If there are Remaining Funds, the Foundation will have until [***] to propose additional scopes of work (whether in 
connection  with  a  new  Global  Health  Project  or  further  development  on  an  existing  Global  Health  Project)  to  be  funded  using  such 
Remaining Funds; provided that if the Foundation has proposed scopes of work to be funded using Remaining Funds but the Company has 
not agreed to such scopes of work by [***], then such date will be extended until such time as the parties have mutually agreed on the scopes 
of work (which scopes of work will be designed to be completed within [***] after commencement).  The Company will use (or allocate to 
agreed scopes of work, as applicable) any Remaining Funds that the Foundation has not requested to be redeployed by [***] (or the extended 
date  pursuant  to  the  preceding  sentence,  if  applicable)  solely  in  accordance  with  Section  2(c)(1).  Any  dispute  pursuant  to  this  Letter 
Agreement  regarding  whether  it  is  scientifically  or  technically  feasible  to  continue  a  Global  Health  Project  or  whether  there  has  been  a 
scientific or technical failure will be resolved in accordance with the dispute resolution procedure described in Section 17 herein. 

(vi) If the Foundation requests that the Company continue further development of the HIV Vaccine Product, TB Vaccine 
Product,  and/or  any  Vaccinal  Antibody  Product,  or  the  Foundation  and  the  Company  proceed  with  one  or  more  additional  Global  Health 
Projects pursuant to Sections 3(a)(iv) or 3(a)(v), any such further development or Global Health Project will be documented in a definitive 
agreement  mutually  agreed  in  good  faith  between  the  Foundation  (or  a  Foundation-supported  Entity)  and  the  Company  and  project  plan, 
which may include [***]. The Foundation and the Company will [***]. The specific level of funding responsibilities for the additional work 
will  be  decided  as  mutually  agreed  in  good  faith  in  writing  by  the  parties.  The  Foundation  shall  be  [***].  Any  additional  work  may  be 
divided into milestones or phases. The Foundation will have the right, at its sole discretion, to continue providing funding (directly or through 
a  Foundation-supported  Entity)  to  advance  the  HIV  Vaccine  Product,  TB  Vaccine  Product,  any  Vaccinal  Antibody  Product,  and/or  any 
product  developed  in  connection  with  any  other  Global  Health  Project  through  to  product  launch  of  a  final  product  for  the  purpose  of 
enabling Global Access. In the event the parties [***]. 

In addition, if the HIV Vaccine Product, TB Vaccine Product, any Vaccinal Antibody Product, and/or any products developed under 
the additional Global Health Project proceeds to [***], the Company will work in good faith with the Foundation to develop and execute 
[***] that will enable the Company to [***]. The [***] will be determined by the Foundation and the Company based upon [***]. The price 
of  such  products  in  Developing  Countries  will  be  such  that  the  products  are  affordable  to  the  Foundation’s  target  beneficiaries  in  the 
Developing Countries, but in no case will the price exceed COGS plus [***]. The [***]. The specific level of funding responsibilities for 
such plan will be decided as mutually agreed in good faith in writing by the parties. The Foundation shall be [***]. The Foundation will have 
the right to inspect the Company’s records pursuant to Section 7 herein, in order [***] for so long as is necessary to ensure compliance with 
this Section 3(a)(vi).

progress of the Global Health Projects towards meeting the Charitable Objectives according to the following framework. 

(vii) Global Health Project Governance and Oversight. The Parties will cooperate together in good faith to oversee the 

Vaccine Program, TB Vaccine Program, Vaccinal Antibody 

(A) Project Level Meetings.  On a [***] basis, and in addition on an ad hoc basis as needed, [***] for each of the HIV 

8

Development Program, and any other Global Health Project then in process to discuss the progress for each respective project. Should these 
meetings identify issues that cannot be resolved by the project team, senior leadership may be engaged in alignment with Section 3(a)(vii)(B) 
below.

(B)  Escalation.  For  issues  escalated  by  the  Project  Level  Meetings  or  that  arise  independently  that  require  real  time 
senior-level communication, there will be ad hoc discussions between a designated senior representative of the Company (e.g., VP level or 
above member of the Company’s research leadership team) and one senior representative of the Foundation (e.g., Director or Senior Advisor 
level).

(C)  [***]  Evaluation  Meetings.  On  a  [***],  the  Company  and  the  Foundation  will  meet  to  discuss  each  of  the  HIV 
Vaccine  Program,  TB  Vaccine  Program,  Vaccinal  Antibody  Development  Program,  and  any  other  Global  Health  Project  then  in  process. 
Subject to applicable laws including Antitrust Laws, the Company agrees to provide written materials to the Foundation representatives at 
least [***] days in advance of such meetings to inform the Foundation representatives of the progress of the Global Health Project and form 
the  basis  for  a  discussion  of  the  Global  Health  Project.  Such  meetings  will  include  applicable  representatives  of  the  R&D,  program 
leadership, global health, alliance management and other relevant functional team membership from the Company, and the relevant program 
strategy team and the strategic investment fund from the Foundation.

(D) Significant Milestone Meetings. The Company and the Foundation representatives outlined in Section 3(a)(vii)(C) 
above will also meet at to be agreed upon milestones in the development plan for any Global Health Project (such as upon the results of a 
clinical trial or when making candidate selection decisions). 

(E) All such meetings will be in person if so requested by the Company or the Foundation, and otherwise may be held by 
videoconference or teleconference. For clarity, the parties may mutually agree to combine meetings for any Global Health Projects as may be 
appropriate. From time to time, as may be agreed upon by the parties, the discussions may include representatives from other entities, such as 
[***] subject to applicable laws including applicable Antitrust Laws.

(viii)  The  Company  will  ensure  that  any  Funded  Developments  that  are  applicable  for  the  treatment,  prevention,  or 
amelioration  of  any  Target  Diseases  and  Conditions,  and  all  products  (at  any  stage  of  development,  e.g.,  from  discovery  through 
commercialization) relating to or arising out of any Global Health Project, will be made available and accessible at an affordable price to 
people  most  in  need  within  Developing  Countries,  which  price  will  not  exceed  COGS  plus  [***].  The  Foundation  will  have  the  right  to 
inspect the Company’s records pursuant to Section 7 in order to [***] for so long as is necessary to ensure compliance with this Section 3(a)
(viii).

(b)  Coordination  with  Foundation-supported  Entities.  The  Company  acknowledges  that  the  Foundation  is  currently  funding 
research and development projects at various Foundation-supported Entities that are relevant to the development of the HIV Vaccine Product 
and the TB Vaccine Product, including [***], and their respective Affiliates. Subject in all respects to applicable law, including applicable 
Antitrust Laws, in connection with the work to be performed on the Platform Technology, HIV Vaccine Program, and TB Vaccine Program 
pursuant to this Letter Agreement, the Company shall cooperate with these entities in good faith to coordinate its development efforts on the 
HIV Vaccine Program and TB Vaccine Program with these entities. This process may include [***]. While the coordination, acquisition of 
rights, and completion of [***] referred  to  in  this  paragraph  are  the  responsibility  of  the  Company  to  effect,  the  Foundation  will  assist  in 
these efforts, in particular those that relate to work funded by the Foundation. Nothing in this Letter Agreement constitutes a commitment by 
the Foundation to make any grants to the Company or a Foundation-supported Entity and the decision to 

9

proceed with a grant will be made solely at the Foundation’s discretion. For clarity, no provision of this Letter Agreement will limit or restrict 
the  Foundation’s  rights  pursuant  to  any  grant  agreement  or  other  contract  with  any  third-party.  Notwithstanding  anything  to  the  contrary, 
nothing in this Letter Agreement shall require the Company to cooperate or otherwise coordinate with Foundation-supported Entities if doing 
so would be reasonably likely to violate or give rise to risk of liability under any applicable law, including applicable Antitrust Laws. 

(c) [***].

(d) Compliance with Intellectual Property Rights: The Company represents and warrants that, as of the Amendment Effective 
Date,  to  the  actual  knowledge  of  the  Company,  the  Company  has  all  necessary  rights  to  the  Platform  Technology  in  existence  at  the 
Amendment Effective Date, the HIV Vaccine Product, the TB Vaccine Product, and the Vaccinal Antibody Product (including all rights in 
any  patents,  copyrights,  trademarks,  trade  secrets,  data,  confidential  information,  know-how,  or  other  intellectual  property  or  proprietary 
right) required to fulfill the Company’s obligations under this Letter Agreement and to grant the licenses expressly granted by the Company 
hereunder.  The  Company  covenants  that  in  the  performance  of  the  HIV  Vaccine  Program,  TB  Vaccine  Program,  Vaccinal  Antibody 
Development Program, and any other Global Health Project, the Company will [***] the Platform Technology, the HIV Vaccine Product, the 
TB  Vaccine  Product,  the  Vaccinal  Antibody  Product,  and  any  product  developed  in  connection  with  any  other  Global  Health  Project 
(including  all  rights  in  any  patents,  copyrights,  trademarks,  trade  secrets,  data,  confidential  information,  know-how,  or  other  intellectual 
property or proprietary right) required to fulfill the Company’s obligations under this Letter Agreement and any other agreement between the 
Foundation  and  the  Company  related  to  the  development  of  such  products  and  to  grant  the  licenses  expressly  granted  by  the  Company 
hereunder. In connection with the Funded Developments the Company shall comply with all applicable laws and regulations and shall not 
knowingly violate third-party intellectual property. 

The Company will [***] with respect to any Platform Technology acquired or licensed in the future (whether through acquisition of 
any business, company, or assets, by contract, or otherwise) required to fulfill the Company’s obligations under this Letter Agreement and 
any  other  agreement  between  the  Foundation  and  the  Company  related  to  the  development  of  any  products  in  connection  with  a  Global 
Health Project and to grant the licenses expressly granted by the Company hereunder.  Without limiting the foregoing, the Company shall 
[***],  including  sufficient  use  rights  for  Global  Health  Projects,  sublicense  rights  encompassing  the  grant  of  rights  to  the  Foundation 
hereunder, and payment provisions that are consistent with those herein and minimize or eliminate any fees, royalties, milestones, or other 
payments on account of any use for Global Access and the grant and exercise of the sublicense to the Foundation hereunder.

Without limiting the foregoing, the Company agrees that it will [***].  In addition, the Company [***].  In the event any milestones 
or  royalties  are  payable  to  [***]  on  sales  of  a  product  developed  in  connection  with  any  Global  Health  Project  intended  for  use  in  the 
Developing Countries, such amounts would be included in the definition of COGS with respect to such product.

(e) Publication. The Company will use [***] to: 

(i)  Publish  the  scientific  results  and  information  developed  in  connection  with  each  Global  Health  Project  within  a 
reasonable period of time after the information or results are obtained, with due regard to reasonable delays or limitations on content of these 
publications that are necessary to protect intellectual property.

(ii) [***].

10

 
 
(iii) [***]. 

“open access” terms and conditions consistent with the Foundation’s Open Access Policy attached hereto as Appendix 7. 

(iv) If the Company seeks publication of Funded Developments in a peer reviewed journal, such publication must be under 

(f) Non-Exclusive License. 

(i) Solely upon the occurrence, if any, of a License Trigger, and only in such event, the Company hereby grants the Foundation a 
[***]; provided that, in each case, the license to the Funded Developments and the Platform Technology is limited [***]. The Foundation and 
the Company agree and acknowledge that, in order to achieve Global Access and make the Funded Developments available and accessible in 
Developing Countries, certain activities may be required to occur in one or more developed countries, like manufacture, distribution, or sale 
(such  as  to  an  entity  procuring  a  product  for  use  in  Developing  Countries).  Accordingly,  the  license  to  the  Foundation  shall  [***].  The 
definitive  agreements  with  respect  to  any  additional  Global  Health  Project  will  include,  to  the  extent  applicable,  license  provisions  with 
respect to the Global Health Project consistent with the license provisions set forth in this Letter Agreement. For the avoidance of doubt, to 
the extent any additional fees, royalties, milestones or other payments are payable to any third-party solely as a result of the Company’s grant 
of, or the Foundation’s exercise of, the license granted pursuant to this paragraph, the Foundation shall be responsible for all such payments 
to the extent such fees, royalties, milestones or other payments are for the benefit of the Foundation or a Foundation-supported Entity and the 
payment of such fees, royalties, milestones or other payments would not constitute a taxable expenditure under Treasury Regulation 53.4945-
6(a)-(b); provided, that the Company may renounce any non-incidental benefit received by the Company related thereto and, in such event, 
the Foundation shall pay the full amount of such additional fees, royalties, milestones or other payments. 

(ii) License Triggers. Notwithstanding the forgoing license grants, the Foundation shall only exercise its rights under the license 
(including its sublicensing rights) during the pendency of the occurrence of at least one of the following, and, in any event, not prior to the 
end of the [***] period set forth in the last paragraph of this Section 3(f)(ii) (each a “License Trigger”):

(A) a Charitability Default;

(B) the Company either: (i) indicates in writing that it is unwilling or unable to commence, proceed, or continue 
with  development  of  the  HIV  Vaccine  Product,  TB  Vaccine  Product,  Vaccinal  Antibody  Product,  or  any  other  Global  Health  Project 
previously  agreed  to  by  the  Company,  or  (ii)  fails  to  commence,  proceed,  or  continue  with  development  of  the  HIV  Vaccine  Product,  TB 
Vaccine  Product,  Vaccinal  Antibody  Product,  or  such  other  Global  Health  Project  within  [***]  of  receipt  of  a  written  notice  from  the 
Foundation [***]. For the avoidance of doubt, a License Trigger shall not be deemed to have occurred pursuant to this Section 3(f)(ii)(B) if 
the  HIV  Vaccine  Program,  the  TB  Vaccine  Program,  the  Vaccinal  Antibody  Development  Program,  or  any  other  Global  Health  Project  is 
[***]; or  

liquidation, or similar proceeding relating to it under the laws of any jurisdiction or any such proceeding is instituted against the Company.

(C) the Company institutes any bankruptcy, insolvency, reorganization for the benefit of creditors, dissolution, 

If  either  the  Foundation  or  the  Company  becomes  aware  of  a  License  Trigger,  it  will  promptly  notify  the  other  party  in  writing  of  the 
occurrence of a License Trigger, setting forth in reasonable detail the reasons therefor. If the Company disputes the Foundation’s belief that a 
License Trigger has occurred, the Company and the Foundation will [***], after which time, such dispute will be decided in accordance with 
the dispute resolution procedure described in Section 17 herein. If the parties have not resolved such dispute prior to 

11

the end of the License Negotiation Period, then during the pendency of the dispute resolution procedure described in Section 17 herein, the 
Foundation may exercise the license pursuant to Section 3(f)(i) and the Company will enable the Foundation to do so pursuant to Section 3(h) 
(and the dispute resolution procedure shall continue notwithstanding the exercise of such license grant), provided that: [***]; (y) until such 
time as the dispute is finally decided against the Company pursuant to the dispute resolution procedure described in Section 17: [***]; and (z) 
if the dispute is finally decided in favor of the Company pursuant to the dispute resolution procedure described in Section 17: [***]. 

(g) Modifications. The principal purpose of the license granted to the Foundation is to ensure that Global Access is achieved as 
rapidly as reasonably practicable. The parties acknowledge that product launch and/or distribution of Company products and processes for 
the benefit of end users in Developing Countries may require worldwide commercialization and /or distribution rights to be maintained by a 
single  party.  During  the  implementation  of  the  Global  Health  Projects,  the  Company  may  demonstrate,  on  a  case-by-case  basis,  to  the 
satisfaction  of  the  Foundation  that  Global  Access  can  best  be  achieved  in  a  particular  case  without  such  a  license.  In  such  a  case,  the 
Foundation and the Company may modify or terminate in whole or in part the foregoing license as mutually agreed as reflected in a signed 
writing.

(h)  Cooperation;  Technology  Transfer.  The  Company  agrees  to  use  Reasonable  Efforts  to  enable  the  Foundation  or  its 
sublicensees to exercise their rights hereunder, which efforts shall include, as reasonably required, [***]. For the avoidance of doubt in the 
event  of  an  exercise  of  the  license  pursuant  to  Section  3(f),  the  obligations  under  this  paragraph  shall  not  require  the  Company  to  incur 
additional expenses or to make additional payments to [***], unless the Foundation or a Foundation-supported Entity is willing to pay such 
additional expenses or payments. 

In  connection  with  the  exercise  of  the  foregoing  licenses  under  Section  3(f),  the  Company’s  use  of  Reasonable  Efforts  shall  include,  as 
reasonably required: [***]. The Foundation will pay all reasonable third-party costs and expenses incurred by the Company as a result of 
complying with the preceding sentence, if any.  

(i) Duration. The Global Access Commitments commenced on December 23, 2016, and are ongoing and will continue for as long 
as  the  Foundation  continues  to  be  a  charitable  entity  (including  following  the  exercise  of  the  Withdrawal  Right).  For  clarity,  the  Global 
Access Commitments will continue as to any Funded Developments that are assigned, sold, transferred, or exclusively licensed to a third-
party. 

4. Third-Party Costs.

Except  as  otherwise  provided  in  this  Letter  Agreement,  the  Company  shall  be  responsible  for  all  costs  associated  with  its 
technology and intellectual property owned, controlled or licensed-in.  Without limiting the foregoing, the Company shall use Reasonable 
Efforts to [***].

5. Obligations in the Event of a Sale of the Platform Technology or Company; Preservation of Global Access Commitments.

In the event that all or substantially all of the Company’s assets, the Platform Technology owned or controlled by the Company, or 
the  Funded  Developments  are  transferred  to,  exclusively  licensed  to,  sold  or  acquired  by  a  third-party,  the  Company  will  require  the 
purchaser, transferee, licensee, or acquirer to assume the Global Access Commitments in a written agreement that is reasonably acceptable to 
the  Foundation.  The  Company  will  not  grant  to  a  third-party  any  rights  or  enter  into  any  arrangements  or  agreements  (including  any 
amendment or modification to the Existing Agreements) that would limit or restrict the Foundation’s rights pursuant to the Global Access 
Commitments, including the Foundation’s 

12

 
right to enter into Global Health Projects with the Company, unless such third-party expressly assumes such Global Access Commitments to 
the reasonable satisfaction of the Foundation. Consistent with the preceding sentence, the Company covenants that if the Company decides to 
no longer pursue the TomegaVax technology and is required to negotiate in good faith with the individuals who are parties to the Existing 
Agreements (collectively, the “Consultants”) to find an alternative manner in which the Consultants can continue to develop the TomegaVax 
technology, the Company will not enter into any exclusive arrangement with the Consultants or grant to the Consultants any rights or enter 
into any arrangements or agreements that would limit or restrict the Foundation’s rights pursuant to the Global Access Commitments. For 
clarity, notwithstanding anything to the contrary in this Letter Agreement, (a) the Foundation’s rights hereunder which exist on the date of the 
transfer, sale, or acquisition of the Company’s Platform Technology, Funded Developments, or other assets to or by a third-party shall not be 
terminated by such transfer, sale, or acquisition and (b) if a third-party acquires the Company, any capabilities, technology, and intellectual 
property rights which the third-party acquirer owned prior to the closing of any such acquisition transaction or develops or acquires after the 
closing of any such transaction without any use of the Funded Developments will not be considered Platform Technology.

6. Withdrawal Right. 

(a) The Withdrawal Right described and defined in this Section 6 will be triggered only as a result of a Charitability Default. For the 
avoidance  of  doubt,  the  Withdrawal  Right  and  the  Charitability  Default  will  not  be  triggered  by  [***],  so  long  as  the  Company  has  not 
breached its obligations under this Letter Agreement.

(b) A “Charitability Default” will occur if the Company either (i) fails to comply, in any material respect, with the restrictions in 
Sections 2(c) and 9 of this Letter Agreement on the use of funds from the Foundation Investment or the other related U.S. legal obligations 
set forth in this Letter Agreement, including without limitation the requirements set forth in Sections 7, 11, and 12 below, or (ii) is in material 
breach  of  the  Global  Access  Commitments.  Each  party  agrees  to  promptly  notify  the  other  party  in  writing  if  it  has  knowledge  of  any 
Charitability Default and the Company shall thereafter provide to the Foundation a proposed strategy to remedy the Charitability Default. 

(c) If the Company fails to cure the Charitability Default within [***] of receipt of the above described notice (provided that solely 
for purposes of this Section 6 in the event the Company disputes that a Charitability Default has occurred, such [***] period will commence 
upon  a  decision  that  a  Charitability  Default  has  occurred  pursuant  to  the  dispute  resolution  process  described  in  Section  17);  and  the 
Foundation holds any securities of the Company issued in connection with the Foundation Investment, including securities issued in respect 
of  or  upon  conversion  or  exercise  of  such  securities  (collectively,  the  “Foundation  Stock”),  the  Company  shall  have  the  obligation,  if 
requested  by  the  Foundation,  to  redeem  or  arrange  for  a  third-party  to  purchase  all  (but  not  less  than  all)  of  the  Foundation  Stock  (the 
“Withdrawal  Right”),  provided  that  any  such  redemption  or  repurchase  shall  be  made  only  to  the  extent  permitted  by  applicable  law 
concerning  distributions  to  holders  of  equity  interests.  Without  limiting  the  foregoing,  if  the  Company  is  unable  to  redeem  all  of  the 
Foundation Stock, and no third-party purchases the Foundation Stock, then the Company shall use commercially reasonable efforts to effect 
the  Withdrawal  Right,  consistent  with  the  Code  and  applicable  law,  as  soon  as  practicable  thereafter,  provided  that  to  the  extent  any 
redemption of the Foundation Stock pursuant to this Section 6(c) would have [***]. For the avoidance of doubt, the Foundation shall cease to 
be a stockholder for all purposes effective as of the date such Foundation Stock is redeemed and, thereafter, the sole right of the Foundation 
with  respect  to  its  ownership  of  Foundation  Stock  shall  be  to  receive  such  redemption  payment.  During  the  period  when  the  Company  is 
unable  to  exercise  its  obligation  to  redeem  or  find  a  purchaser  of  the  Foundation  Stock,  the  Company  shall  [***]  until  such  time  as  the 
Company has fulfilled the Withdrawal Right with respect to all of the Foundation Stock).

13

(d) For redemption or purchase by a third-party pursuant to Section 6(c), Foundation Stock shall be valued at the greater of (i) the 
original purchase price attributable to such shares (the “Minimum Purchase Price”) or, at the option of the Foundation, (ii) the then current 
Fair Market Value. 

(e) If the Foundation Stock is sold or redeemed in connection with a Withdrawal Right, the Foundation will have a look back right 
by which, in the event that (i) the Company consummates a Sale Transaction or (ii) the Company signed a binding letter of intent or binding 
term sheet or entered into any definitive agreement (each, a “Binding Agreement”) with respect to such Sale Transaction  at any time prior 
to  the  [***]  anniversary  of  the  first  date  that  any  of  the  Foundation  Stock  was  redeemed  or  sold,  then  the  Foundation  will  receive 
compensation equal to the excess of what it would have received in such transaction if it still held the Foundation Stock at the time of such 
Sale  Transaction  over  what  it  actually  received  in  the  sale  or  redemption  of  the  Foundation  Stock;  provided  that  such  Sale  Transaction  
actually  closes  prior  to  the  first  anniversary  of  the  first  date  that  any  of  the  Foundation  Stock  was  redeemed  or  sold.  For  clarity,  if  the 
Company does not enter into any Binding Agreement until after the [***] anniversary of the initial sale or redemption date of the Foundation 
Stock, then the Foundation’s look-back right set forth in this Section 6(e) will terminate and be of no further force and effect.

(f) If at the time that the Foundation has requested to exercise its Withdrawal Right, the Foundation Stock consists of a class of 
securities  of  the  Company  that  (i)  is  registered  under  section  12  (or  any  successor  provision)  of  the  Securities  Exchange  Act  of  1934,  as 
amended (the “Exchange Act”),  (ii)  is  not  subject  to  restrictions  from  trading  under  the  Securities  Act  or  state  securities  laws  and  (iii)  is 
listed  on  a  U.S.  national  securities  exchange  and  the  Company  is  current  in  filing  its  financial  reports  and  other  required  filings  with  the 
Securities and Exchange Commission (the “SEC”), then the Company will not be required to redeem or find a purchaser for the Foundation 
Stock if the Foundation elects to and is able to sell the Foundation Stock on a securities exchange for at least the Minimum Purchase Price. If 
the  Foundation  elects  to  sell  the  Foundation  Stock  to  the  public  pursuant  to  this  Section  6(f)  and  the  Foundation  receives  less  than  the 
Minimum Purchase Price, then the Company will pay the Foundation as soon as practicable the difference between the amount received by 
the Foundation as a result of the sale of the Foundation Stock on the securities exchange and the amount of the Minimum Purchase Price. 

(g) For the avoidance of doubt, notwithstanding any exercise of the Withdrawal Right, the Foundation will continue to be entitled to 

enforce its rights under the Global Access Commitments. 

7. Required Reporting; Audit Rights 

In  addition  to  any  reports  required  to  be  delivered  to  the  Foundation  pursuant  to  the  Investment  Documents,  the  Company  shall 

furnish, or cause to be furnished, to the Foundation the following reports and certifications:

(a) Within [***] after the end of each of the Company’s fiscal years during which the Foundation owns any Foundation Stock or 
any  loans  from  the  Foundation  to  the  Company  are  outstanding,  a  certificate  from  the  Company  signed  by  an  officer  or  director  of  the 
Company and substantially in the form attached to this Letter Agreement as Appendix 7, certifying that the requirements of the Foundation 
Investment set forth in this Letter Agreement were met during the immediately preceding fiscal year, describing the use of the proceeds of the 
Foundation Investment and summarizing the Company’s progress toward achieving the Global Access Commitments;

(b) Within [***] after the end of the Company’s fiscal year during which the Foundation ceases to own any Foundation Stock or all 
loans from the Foundation to the Company cease to be outstanding, a certificate from the Company signed by an officer or director of the 
Company and substantially in the form attached to this Letter Agreement as Appendix 8, certifying that the requirements of the Foundation 

14

Investment set forth in this Letter Agreement were met during the term of the Foundation Investment, describing the use of the proceeds of 
the Foundation Investment and summarizing the Company’s progress toward achieving the Global Access Commitments; 

(c) Any other information respecting the operations, activities, and financial condition of the Company as the Foundation may from 
time to time reasonably request to discharge any expenditure responsibility, within the meaning of Sections 4945(d)(4) and 4945(h) of the 
Code, of the Foundation with respect to the Foundation Investment, and to otherwise monitor the charitable benefits intended to be served by 
the Foundation Investment; provided, that the Foundation will reimburse the Company for any reasonable third-party expenses incurred by 
the Company in order to prepare any information the Company is required to prepare solely as a result of this Section 7(c); and

(d) Full and complete financial reports of the type ordinarily required by commercial investors under similar circumstances to the 
extent required pursuant to Treasury Regulation 53.4945-5(b)(4); provided that as long as the Company is a reporting company under the 
Exchange Act, the timely filing of quarterly, annual and current reports pursuant to section 13 or 15(d) of the Exchange Act and all other 
required filings with the SEC shall be deemed to satisfy the financial reporting obligations in this Section 7(d).

(e)  The  Company  will  maintain  books  and  records  adequate  to  provide  information  ordinarily  required  by  commercial  investors 
under  similar  circumstances,  including  copies  of  any  reports  submitted  to  the  Foundation  related  to  each  Global  Health  Project.  The 
Company will retain such books, records, and reports for [***] and will make such books, records, and reports available at reasonable times 
to enable the Foundation to [***]. 

(f)  The  Company  will  permit  employees  or  agents  of  the  Foundation  who  are  bound  by  written  confidentiality  obligations  or 
policies at least as restrictive as those set forth herein, at any reasonable time and upon reasonable prior notice, during normal business hours, 
to  examine  or  audit  the  Company’s  books  and  accounts  of  record  and  to  make  copies  and  memoranda  of  the  same,  in  each  case,  at  the 
Foundation’s  expense,  to  audit  the  Company’s  compliance  with  the  use  of  the  Foundation’s  funds;  provided  that  the  Foundation  will  not 
conduct such an examination more frequently than once per year unless: (i) required due to an audit, request, or inquiry of the Foundation by 
the  Internal  Revenue  Service;  or  (ii)  the  Foundation  has  a  reasonable  belief  that  a  Charitability  Default  has  occurred.  If  the  Company 
maintains any records (including without limitation computer generated records and computer software programs for the generation of such 
records)  in  the  possession  of  a  third-party,  the  Company,  upon  request  of  the  Foundation,  will  notify  such  party  to  permit  the  Foundation 
access to such records at reasonable times and to provide the Foundation with copies of any records it may reasonably request in connection 
with such audit, request or inquiry, all at the Foundation’s expense.  

8. Assignment.

Notwithstanding  anything  in  this  Letter  Agreement  to  the  contrary,  (a)  the  Foundation  will  have  the  right  to  assign  this  Letter 
Agreement (in whole but not in part) or transfer the Foundation Stock, subject to securities laws, to (i) any successor charitable organization 
of the Foundation from time to time that is a tax exempt organization as described in Section 501(c)(3) of the Code, or (ii) any tax exempt 
organization as described in Section 501(c)(3) of the Code controlled by one or more trustees of the Foundation; and (b) the Company will 
have the right to assign this Letter Agreement (in whole but not in part) without the consent of the Foundation or any other person: (x) in 
connection  with  a  Sale  Transaction,  subject  to  the  terms  of  Section  5;  and  (y)  to  any  Affiliate  of  the  Company  (provided,  that:  (A)  such 
Affiliate has adequate financial resources to perform the Company’s obligations under this Letter Agreement; and (B) in the event any such 
Affiliate ceases to have adequate financial resources to perform the Company’s obligations under 

15

this Letter Agreement, the Company shall be secondarily liable for such obligations). Except as provided in the preceding sentence, neither 
party shall have the right to assign (whether by merger, sale of stock, sale or license of assets, or otherwise) this Letter Agreement without the 
prior written consent of the other party, which consent will not be unreasonably withheld, conditioned, or delayed. The Foundation or the 
Company,  as  applicable,  will  notify  the  other  party  of  any  such  proposed  assignment,  including  the  identity  of  the  assignee,  in  a  timely 
manner. For the avoidance of doubt, if the Foundation transfers the Foundation Stock as permitted by this Section 8, the Foundation may 
assign to any such transferee all of its rights attached to such Foundation Stock, including the Withdrawal Right.

9. Prohibited Uses.

The  Company  shall  not  expend  any  proceeds  of  the  Foundation  Investment  to  carry  on  propaganda  or  otherwise  to  attempt  to 
influence  legislation,  to  influence  the  outcome  of  any  specific  public  election  or  to  carry  on,  directly  or  indirectly,  any  voter  registration 
drive,  or  to  participate  or  intervene  in  any  political  campaign  on  behalf  of  or  in  opposition  to  any  candidate  for  public  office  within  the 
meaning of Section 4945(d) of the Code. The proceeds of the Foundation Investment shall not (a) be earmarked to be used for any activity, 
appearance or communication associated with the activities described in the foregoing sentence, or (b) be intended for the direct benefit, and 
will not directly benefit, any person actually known to the Company (including after being identified to the Company by the Foundation) as 
having  a  personal  or  private  interest  in  the  Foundation,  including  without  limitation,  descendants  of  the  founders  of  the  Foundation,  or 
persons related to or controlled by, directly or indirectly, such persons; provided, that in no event shall the Company (or any of its officers, 
directors, employees, agents, or representatives) have any duty of inquiry with respect to the foregoing.

For  the  avoidance  of  doubt,  except  as  otherwise  expressly  permitted  in  this  Letter  Agreement,  the  Company  will  not  use  the 

Foundation Investment to pay a dividend or redeem shares.

10. Disqualified Person. 

The Company represents and warrants to the Foundation that, as of the Amendment Effective Date, neither the Company nor, to the 
actual knowledge of the Company, any shareholder of the Company is a “disqualified person” with respect to the Foundation (as the term 
“disqualified  person”  is  defined  in  Section  4946(a)  of  the  Code).  The  Foundation  represents  and  warrants  to  the  Company  that  as  of  the 
Amendment Effective Date, the Foundation does not, and one or more disqualified persons with respect to the Foundation do not, directly or 
indirectly, control the Company.

11. Anti-Terrorism.

The Company will not use any portion of the Foundation Investment, directly or indirectly, in support of activities (a) prohibited by 
U.S. laws related to combatting terrorism; (b) with persons on the List of Specially Designated Nationals (www.treasury.gov/sdn) or entities 
owned or controlled by such persons; or (c) with countries or territories against which the U.S. maintains comprehensive sanctions (currently, 
Cuba,  Iran,  Syria,  North  Korea,  and  the  Crimean  Region  of  Ukraine),  unless  such  activities  are  fully  authorized  by  the  U.S.  government 
under applicable law and specifically approved by the Foundation in its sole discretion.

12. Anti-Corruption and Anti-Bribery.

The  Company  will  not  offer  or  provide  money,  gifts,  or  any  other  things  of  value  directly  or  indirectly  to  anyone  in  order  to 
improperly influence any act or decision relating to the Foundation or any activities contemplated by this Letter Agreement or the Company’s 
organizational documents (e.g., 

16

certificate of incorporation), including by assisting any party to secure an unlawful advantage. Training and information on compliance with 
these requirements are available at www.learnfoundationlaw.org.

13. Public Reports; Use of Name.

Each of the Foundation and the Company may include information on this investment in its periodic public reports and may make 
the  investment  public  at  any  time  on  its  web  page  and  as  part  of  press  releases,  public  reports,  speeches,  newsletters,  and  other  public 
documents; provided that public communications about the Foundation Investment made by the Company shall indicate that the Foundation 
Investment was made by the Foundation in furtherance of the Foundation’s charitable purposes; provided, however, that the Foundation may 
not  publicly  disclose  this  Letter  Agreement  or  the  Antibody  Development  Investment  prior  to  the  Amendment  Effective  Date.  Any 
announcement of the Foundation Investment by any third-party will require the prior written approval of the Foundation and the Company. 
Other than with respect to the foregoing rights, each party shall also obtain the other party’s prior written approval for any other use of the 
other party’s name or logo in any respect; provided, that each party may use the other party’s name for any uses that have been previously 
approved  in  writing  by  such  party.  Notwithstanding  the  foregoing,  each  party’s  name  and  logo  will  not  be  used  by  the  other  party  in  any 
manner to market, sell or otherwise promote the Company, its products, services, and/or business.

14. Indemnification.

(a)  Company  Indemnity.  The  Company  will  indemnify,  hold  harmless,  and  defend  the  Foundation  and  its  co-chairs,  trustees, 
directors,  officers,  employees,  and  representatives  other  than  Foundation  sublicensees  (collectively,  the  “Foundation  Indemnitees”)  from 
and  against  any  and  all  judgments,  settlements,  damages,  penalties,  losses,  liabilities,  and  costs  (including  reasonable  attorneys’  fees  and 
costs) as a result of third-party causes of action, claims, suits, or legal proceedings (each a “Claim”) finally awarded to such third-party by a 
court of competent jurisdiction against any of the Foundation Indemnitees or agreed to as part of a monetary settlement of the Claim and 
arising out of or relating to:  (a) bodily injury, death, or property damage caused by the activities or omissions of the Company, including any 
development, product launch, or commercialization activities carried out by the Company (including any failure to comply with applicable 
laws,  regulations  or  rules  in  connection  therewith),  or  by  any  Company  product  (other  than  to  the  extent  such  Claims  were  caused  by 
commercialization  or  other  activities  conducted  by  a  Foundation  sublicensee  without  the  involvement  of  the  Company  or  any  of  its 
Affiliates); or (b) any Claim that the Platform Technology, any Funded Development or any Company product (other than to the extent such 
Claims  were  caused  by  commercialization  or  other  activities  conducted  by  a  Foundation  sublicensee  without  the  involvement  of  the 
Company or any of its Affiliates) infringes upon a patent, proprietary, or other intellectual property right of a third-party. The Foundation will 
give  the  Company  prompt  written  notice  of  any  Claim  subject  to  indemnification  pursuant  to  this  Section  14(a);  provided  that  the 
Foundation’s failure to promptly notify the Company will not affect the Company’s indemnification obligations except to the extent that the 
Foundation’s  delay  prejudices  the  Company’s  ability  to  defend  the  Claim.  The  Company  will  have  sole  control  over  the  defense  and 
settlement  of  each  and  every  Claim  subject  to  indemnification  pursuant  to  this  Section  14(a),  with  counsel  of  its  own  choosing  which  is 
reasonably acceptable to the Foundation; provided that the Company conducts the defense actively and diligently at the sole cost and expense 
of the Company and provided further that the Company will not enter into any settlement that adversely affects, in any material respect, any 
Foundation Indemnitee without the applicable Foundation Indemnitee’s prior written consent, such consent not to be unreasonably withheld, 
conditioned or delayed. The Foundation will provide the Company, upon request, with reasonable cooperation in connection with the defense 
and settlement of the Claim. Subject to the Company’s rights above to control the defense and settlement of Claims, the Foundation and any 
Foundation Indemnitee may, at its own expense, employ separate counsel to monitor and participate in the defense of any Claim under this 
Section 14(a). For the avoidance of doubt, the Company shall have no liability to the Foundation or 

17

any  obligation  to  indemnify  the  Foundation  pursuant  to  this  Section  14(a)  to  the  extent  such  claim  arises  out  of  the  Foundation’s  fraud, 
negligence, or willful misconduct. 

(b)  The  parties  will  not  be  liable  to  each  other  for  any  indirect,  incidental,  consequential,  or  special  damages  (including  lost 
revenues, lost savings, or lost profits suffered by such other party) suffered by such other party arising under or in connection with this Letter 
Agreement,  regardless  of  the  form  of  action,  whether  in  contract  or  tort,  including  negligence  of  any  kind  whether  active  or  passive,  and 
regardless of whether the party knew of the possibility that such damages could result; provided that to the extent a Foundation Indemnitee is 
entitled  to  be  indemnified  hereunder  for  Claims  of  third  parties  and  such  third-party  has  been  awarded  indirect,  incidental,  consequential, 
reliance,  or  special  damages  (including  lost  revenues,  lost  savings,  or  lost  profits),  the  Company’s  indemnification  obligations  to  the 
Foundation  Indemnitee  shall  extend  to  and  include  such  third-party’s  indirect,  incidental,  consequential,  reliance,  or  special  damages 
(including lost revenues, lost savings, or lost profits). The parties further agree that under no circumstances will any party be liable to the 
other party (or to any Foundation Indemnitee) more than once for the same losses arising under or in connection with this Letter Agreement.

(c)  The  Foundation  agrees  that  it  will,  as  a  condition  to  the  grant  of  any  sublicense  hereunder,  enter  into  an  agreement  with  the 
sublicensee(s) that is consistent with industry standards at the time with respect to indemnification of the Company for costs, liabilities, and 
expenses arising from the conduct of activities by or on behalf of such sublicensee(s) in exercising such sublicense.

15. Entire Agreement; Modification. 

The terms and conditions set forth in this Letter Agreement are in addition to the provisions stated in the Investment Documents and 
the terms and conditions of this Letter Agreement shall prevail over any inconsistent provision in any Investment Document. Unless mutually 
agreed  otherwise  by  the  Parties,  to  the  extent  any  of  the  Global  Access  Commitments  (including,  for  clarity,  the  definitions  of  Funded 
Developments  and  Platform  Technology)  in  this  Letter  Agreement  are  inconsistent  with  any  global  access  terms  in  any  existing  grant 
agreements between the Parties in connection with the HIV Vaccine Program and TB Vaccine Program, or future grant agreements (including 
any  amendments  to  existing  grant  agreements)  with  respect  to  the  development  of  the  HIV  Vaccine  Product,  TB  Vaccine  Product,  HIV 
Vaccinal Antibody Product, and/or Malaria Vaccinal Antibody Product up through the completion of the first Phase 2 clinical trial for such 
respective  product,  the  terms  and  conditions  of  this  Letter  Agreement  shall  prevail  solely  to  the  extent  necessary  to  resolve  such 
inconsistency.  The  Parties  acknowledge  that  current  and  future  grant  agreement-specific  global  access  terms  that  are  not  included  in  this 
Letter Agreement may be necessary to advance global access objectives prior to the completion of the first Phase 2 clinical trial for each 
respective product as noted in the preceding sentence, but such terms shall not contravene the Global Access Commitments nor modify the 
definitions of Funded Developments and Platform Technology in this Letter Agreement unless mutually agreed by the Parties. No change, 
modification or waiver of any term or condition of this Letter Agreement shall be valid unless it is in writing, it is signed by the party to be 
bound, and it expressly refers to this Letter Agreement.

16. Authority; Governing Law.

Each of the signatories below covenants, represents, and warrants that as of the Amendment Effective Date, he, she, or it had all 
authority necessary to execute this Letter Agreement and that, on execution, this Letter Agreement will be fully binding and enforceable in 
accordance with its terms, and that no other consents or approvals of any other person or third parties are required or necessary for this Letter 
Agreement  to  be  so  binding.  This  Letter  Agreement  shall  be  governed  by  the  laws  of  the  State  of  Washington,  excluding  provisions  of 
conflicts of laws which would result in the application of the law of any other jurisdiction.

18

17. Dispute Resolution. 

(a) Except as specifically otherwise provided herein, any disagreement or dispute between the parties arising out of or related to this 
Letter Agreement (a “Dispute”), shall be resolved in the manner provided in this Section 17. Should there develop a Dispute, such Dispute 
shall be resolved in the order of preference of Sections 17(b) - (d) below.

(b) [***].

(c) [***].

(d) [***].

(e) [***].

(f) [***].

(g) [***]. 

(h) [***].

(i) Both parties agree to continue performing their obligations under this Letter Agreement pending the resolution of any Dispute 
that is being resolved hereunder unless and until such obligations are terminated or expire in accordance with the provisions of this Letter 
Agreement.

(j) Notwithstanding the foregoing, and without waiting for the expiration of the time periods set forth above, each party shall have 
the  right  to  apply  to  any  court  of  competent  jurisdiction  for  appropriate  interim  or  provisional  relief,  as  necessary  to  protect  its  rights  or 
property. Furthermore, nothing herein shall prevent the parties from resorting to a court of competent jurisdiction in those instances where 
preliminary  injunctive  relief  would  be  appropriate,  pending  final  resolution  of  the  Dispute  through  arbitration.  Nothing  in  this  Section  17 
shall  be  construed  to  prevent  a  party  from  instituting  formal  proceedings  at  any  time  to  avoid  the  expiration  of  any  statute  of  limitations 
period  or  to  preserve  a  superior  position  with  respect  to  other  creditors.  For  the  avoidance  of  doubt,  to  the  extent  this  Letter  Agreement 
permits the parties to apply for relief to or institute a proceeding in a court of competent jurisdiction, nothing in this Letter Agreement or any 
other Investment Document will constitute a waiver of the right to a jury trial in such proceeding.

18. Confidential Information.

(a)  Except  to  the  extent  expressly  authorized  by  this  Letter  Agreement  or  otherwise  agreed  in  writing,  the  receiving  party  (the 
“Receiving Party”) shall keep confidential and shall not publish or otherwise disclose or use for any purpose other than as provided for in 
this Letter Agreement any Confidential Information of the other party (the “Disclosing Party”). Notwithstanding the foregoing, Confidential 
Information shall not include any information to the extent that: (i) it can be established by written documentation of the Receiving Party that 
such  information  is  generally  available  to  the  public  other  than  through  unauthorized  disclosure  thereof  by  the  Receiving  Party;  (ii)  such 
information  is  lawfully  acquired  from  other  sources  which  are  not  prohibited  from  disclosing  such  information,  and  without  obligation  of 
confidentiality;  (iii)  such  information  is  approved  for  disclosure  by  the  consent  of  the  Disclosing  Party;  or  (iv)  such  information  is 
independently developed by the Receiving Party without use or reference to the Disclosing Party’s Confidential Information. 

19

(b) Nothing in this Letter Agreement will be interpreted as placing any obligation of confidentiality or non-use on the Receiving 
Party with respect to any Confidential Information that the Receiving Party is required to disclose pursuant to law, regulation, or court order. 
In the event that Confidential Information is required to be disclosed by the Receiving Party pursuant to law, regulation, or court order, the 
Receiving Party shall make all reasonable efforts to notify the Disclosing Party of such requirement, in order to allow the Disclosing Party to 
seek a protective order or seek confidential treatment of such information.

(c) The Receiving Party may disclose Confidential Information of the Disclosing Party to its trustees, directors, officers, employees, 
consultants, and advisors (including lawyers and accountants) on a need to know basis, in each case subject to appropriate confidentiality 
provisions (or professional standards) reasonably acceptable to the Disclosing Party.

(d)  Notwithstanding  any  other  provision  of  this  Letter  Agreement,  nothing  herein  shall  prohibit  the  Foundation  from  any  of  the 
following:  (i)  analyzing  Confidential  Information;  (ii)  comparing  the  Confidential  Information  to  information  in  the  possession  of  the 
Foundation;  or  (iii)  making  any  grant  or  other  investment  to,  or  entering  into  any  agreement  with,  any  third-party  in  furtherance  of  the 
Foundation’s charitable purpose, so long as in doing so, the Foundation does not disclose any Confidential Information except as permitted 
pursuant to Sections 18(a) through (c). 

19. Counterparts.

This Letter Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which 

shall be deemed to be and constitute one and the same instrument.

Appendix 9

Gates Foundation Open Access Policy

The Bill & Melinda Gates Foundation is committed to information sharing and transparency. We believe that published research resulting 
from our funding should be promptly and broadly disseminated. We have adopted an Open Access policy that enables the unrestricted access 
and reuse of all peer-reviewed published research funded, in whole or in part, by the foundation, including any underlying data sets.

As of January 1, 2015, our Open Access policy will be effective for all new agreements. During a two-year transition period, publishers will 
be permitted to apply up to a 12-month embargo period on the accessibility of the publication and its underlying data sets. This embargo 
period will no longer be allowed after January 1, 2017.

Our Open Access policy contains the following elements:

1.

2.

3.

4.

Publications  Are  Discoverable  and  Accessible  Online.  Publications  will  be  deposited  in  a  specified  repository(s)  with  proper 
tagging of metadata. 

Publication  Will  Be  On  “Open  Access”  Terms.  All  publications  shall  be  published  under  the  Creative  Commons  Attribution  4.0 
Generic  License  (CC  BY  4.0)  or  an  equivalent  license.  This  will  permit  all  users  of  the  publication  to  copy  and  redistribute  the 
material  in  any  medium  or  format  and  transform  and  build  upon  the  material,  including  for  any  purpose  (including  commercial) 
without further permission or fees being required. 

Foundation Will Pay Necessary Fees. The foundation would pay reasonable fees required by a publisher to effect publication on 
these terms. 

Publications  Will  Be  Accessible  and  Open  Immediately.  All  publications  shall  be  available  immediately  upon  their  publication, 
without any embargo period.  An embargo period is the period during which the publisher will require a subscription or the payment 
of a fee to gain access to the publication. We are, however, providing a transition period of up to two years from the effective date 
of the policy (or until January 1, 2017). During the transition period, the foundation will allow publications in journals that provide 
up to a 12-month embargo period.

5. Data  Underlying  Published  Research  Results  Will  Be  Accessible  and  Open  Immediately.  The  foundation  will  require  that  data 
underlying the published research results be immediately accessible and open. This too is subject to the transition period and a 12-
month embargo may be applied.

 
 
STOCK PURCHASE AGREEMENT

that:

2.1

Private Placement.  Neither Vir nor any Person acting on its behalf, has, directly or indirectly, made any offers 
or sales of any security or solicited any offers to buy any security, under any circumstances that would require registration of the 
Shares under the Securities Act.  Subject to the accuracy of the representations made by the Foundation in Section 3, the Shares 
will be issued and sold to the Foundation in compliance with applicable exemptions from the registration and prospectus delivery 
requirements  of  the  Securities  Act  and  the  registration  and  qualification  requirements  of  all  applicable  securities  Laws  of  the 
states of the United States.  Vir has not engaged any brokers, finders or agents, or incurred, or will incur, directly or indirectly, 
any liability for brokerage or finder’s fees or agents’ commissions or any similar charges in connection with this Agreement and 
the transactions contemplated hereby.

Organization and Qualification.  Vir is duly incorporated, validly existing and in good standing under the laws 
of  the  State  of  Delaware,  with  full  corporate  power  and  authority  to  conduct  its  business  as  currently  conducted.    Vir  is  duly 
qualified  to  do  business  and  is  in  good  standing  in  every  jurisdiction  in  which  the  nature  of  the  business  conducted  by  it  or 
property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the 
case may be, would not reasonably be expected to have a Material Adverse Effect on Vir. 

2.3

Authorization; Enforcement.  Vir has all requisite corporate power and authority to enter into and to perform 
its obligations under this Agreement, to consummate the transactions contemplated hereby and to issue the Shares in accordance 
with the terms and conditions hereof.  The execution, delivery and performance of this Agreement by Vir and the consummation 
by it of the transactions contemplated hereby (including the issuance of the Shares at the Closing in accordance with the terms 
and conditions hereof) have been duly authorized by the Board and no further consent or authorization of Vir, the Board, or its 
stockholders is required.  This Agreement has been duly executed by Vir and constitutes a legal, valid and binding obligation of 
Vir  enforceable  against  Vir  in  accordance  with  its  terms,  except  as  enforceability  may  be  limited  by  applicable  bankruptcy, 
insolvency, reorganization, or moratorium or similar Laws affecting creditors’ and contracting parties’ rights generally.

2.4

Issuance of Shares.  The Shares are duly authorized and, upon issuance in accordance with the terms of this 
Agreement,  will  be  validly  issued,  fully  paid  and  non-assessable  and  will  not  be  subject  to  preemptive  rights  or  other  similar 
rights of stockholders of Vir.

SEC Documents, Financial Statements.

The Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange Act.  Vir 
has  delivered  or  made  available  (by  filing  on  the  SEC’s  electronic  data  gathering  and  retrieval  system  (EDGAR))  to  the 
Foundation complete copies of its most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, and any report on 
Form 8-K, in each case filed with the SEC after December 31, 2020 and prior to the Execution Date (the “SEC Documents”).  As 
of its date, each SEC Document complied in all material respects with the requirements of the Exchange Act, and other Laws 
applicable to it, and, as of its date, such SEC Document did not contain any untrue statement of a material fact or omit to state a 
material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under 
which they were made, not misleading.  No inquiries or any other investigation conducted by or on behalf of the Foundation or its 
representatives or counsel will modify, amend or affect the Foundation’s right to rely on the truth, accuracy and completeness of 
the SEC Documents and Vir’s representations and warranties contained in this Agreement.

(b)

The financial statements, together with the related notes and schedules, of Vir included in the 
SEC Documents comply as to form in all material respects with all applicable accounting requirements and the published rules 
and regulations of the SEC and all other applicable rules and regulations with respect thereto.  Such financial statements, together 
with  the  related  notes  and  schedules,  have  been  prepared  in  accordance  with  GAAP  applied  on  a  consistent  basis  during  the 
periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto or (ii) in the case of 
unaudited interim statements, to the extent they 

3

 
may not include footnotes or may be condensed or summary statements), and fairly present in all material respects the financial 
condition  of  Vir  and  its  consolidated  subsidiaries  as  of  the  dates  thereof  and  the  results  of  operations  and  cash  flows  for  the 
periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments).

(c)

The Common Stock is listed on Nasdaq, and Vir has taken no action designed to, or that to its 
knowledge is likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or delisting 
the  Common  Stock  from  Nasdaq.    As  of  the  date  of  this  Agreement,  Vir  has  not  received  any  notification  that,  and  has  no 
knowledge that, the SEC or Nasdaq is contemplating terminating such registration or listing.

2.6

Internal  Controls;  Disclosure  Controls  and  Procedures.    Vir  maintains  internal  control  over  financial 
reporting as defined in Rule 13a-15(f) under the Exchange Act.  Vir has implemented the “disclosure controls and procedures” 
(as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) required in order for the principal executive officer and 
principal  financial  officer  of  Vir  to  engage  in  the  review  and  evaluation  process  mandated  by  the  Exchange  Act,  and  is  in 
compliance with such disclosure controls and procedures in all material respects.  Each of the principal executive officer and the

consummation  by  Vir  of  the  transactions  contemplated  hereby  and  thereby  (including  the  issuance  of  the  Shares)  will  not  (i) 
conflict with or result in a violation of any provision of Vir’s Amended and Restated Certificate of Incorporation or Amended and 
Restated Bylaws, each as in effect on the date hereof, (ii) violate or conflict with, or result in a breach of any provision of, or 
constitute a default under, any agreement, indenture, or instrument to which Vir is a party, or (iii)  result in a violation of any Law 
(including  United  States  federal,  state  and  international  securities  Laws  and  regulations  and  regulations  of  any  self-regulatory 
organizations)  applicable  to  Vir,  except  in  the  case  of  clauses  (ii)  and  (iii)  only,  for  such  conflicts,  breaches,  defaults,  and

Foundation.

Vir  is  not  required  to  obtain  any  consent,  authorization  or  order  of,  or  make  any  filing  or 
registration  with,  any  court  or  governmental  agency  or  any  regulatory  agency  or  self-regulatory  organization  in  order  for  it  to

action,  suit,  proceeding  or  investigation  pending  (of  which  Vir  has  received  notice  or  otherwise  has  knowledge)  or,  to  Vir’s 
knowledge, threatened, against Vir or that Vir intends to initiate, except where such action, suit, proceeding or investigation, as 
the case may be, would not reasonably be expected to have a Material Adverse Effect.

Licenses and Other Rights; Compliance with Laws.  Vir has all franchises, permits, licenses and other rights 
and privileges (“Permits”) necessary to permit it to own its properties and to conduct its business as presently conducted and is in 
compliance  thereunder,  except  where  the  failure  to  be  in  compliance  would  not  reasonably  be  expected  to  have  a  Material 
Adverse Effect.  Vir has not taken any action that would interfere with its ability to renew all such Permit(s), except where the 
failure  to  renew  such  Permit(s)  would  not  reasonably  be  expected  to  have,  a  Material  Adverse  Effect.    Vir  is  and  has  been  in 
compliance  with  all  Laws  applicable  to  its  business,  properties  and  assets,  and  to  the  products  and  services  sold  by  it,  except

2.11

Intellectual Property.

(a)

The Intellectual Property that is owned by Vir or its subsidiaries is owned free from any Liens 
or restrictions.  All of Vir’s material Intellectual Property Licenses are in full force and effect in accordance with their terms, are 
free of any Liens or restrictions, and, to Vir’s knowledge, neither Vir, nor any other party thereto, is in material breach of any 
such material Intellectual Property License.  To Vir’s knowledge, no event has occurred that with notice or lapse of time or both 
(i)  would  constitute  a  breach  or  default  of  any  such  material  Intellectual  Property  License,  (ii)  would  result  in  the  termination 
thereof,  or  (iii)  would  cause  or  permit  the  acceleration  or  other  change  of  any  right  or  obligation  or  the  loss  of  any  benefit 
thereunder by Vir or its subsidiaries, except, in the case of each of clauses (i) through (iii), as would not reasonably be expected 
to have a Material Adverse Effect. 

(b)

Except as set forth in the SEC Documents, there is no legal claim or demand of any Person or 
any proceeding that is pending or threatened in writing, (i) challenging the right of Vir in respect of any Intellectual Property of 
Vir,  or  (ii)  claiming  that  any  default  exists  under  any  Intellectual  Property  License,  except,  in  the  case  of  clauses  (i)  and  (ii) 
above,  where  any  such  claim,  demand  or  proceeding  has  not  had,  and  would  not  reasonably  be  expected  to  have,  a  Material 
Adverse Effect.

Except  as  set  forth  in  the  SEC  Documents:  (i)  Vir  or  one  of  its  subsidiaries  owns,  free  and  clear  of  any  Lien  or 
encumbrance, or, to Vir’s knowledge, has a valid license, or an enforceable right to use, as it is used or held for use, all U.S. and 
non-U.S. patents, trade secrets, know-how, trademarks, service marks, copyrights, and other proprietary and Intellectual Property 
rights,  and  all  grants  and  applications  with  respect  to  the  foregoing  (collectively,  the  “Proprietary  Rights”)  necessary  for  the 
conduct of Vir’s business, except where the failure to own or have any of the foregoing would not reasonably be expected to have 
a Material Adverse Effect (such Proprietary Rights owned by or licensed to Vir collectively, the “Vir Rights”);  (ii)  Vir  and  its 
subsidiaries  have  taken  reasonable  measures  to  protect  the  Vir  Rights,  consistent  with  prudent  commercial  practices  in  the 
biotechnology industry, except where failure to take such measures has not had, and would not reasonably be expected to have, a 
Material Adverse Effect, and (iii) without limiting the generality of the preceding, to the best of Vir’s knowledge, Vir’s current 
product  candidates,  if  commercially  sold  at  the  projected  launch,  would  not  infringe  any  unlicensed  third  party  granted  US  or 
non-US patent claims or, if granted without amendment, any unlicensed third party published US or non-US patent application 
claims, except to the extent any such infringement would not reasonably be expected to have a Material Adverse Effect. 

2.12

Health Care Matters.    Vir: (i)  has operated  and  currently  operates  its  business  in  compliance  in  all material 
respects with applicable provisions of the Health Care Laws (as defined below) of the Food and Drug Administration (“FDA”), 
the Department of Health and Human Services and any comparable state, foreign or other regulatory authority to which they are 
subject (collectively, the “Applicable Regulatory Authorities”) applicable to the ownership, testing, development, manufacture, 
packaging, processing, use, sale, promotion, distribution, storage, import, export or disposal of any of Vir’s product candidates or 
any  product  manufactured  or  distributed  by  Vir;  (ii)  has  not  received  any  FDA  Form  483,  written  notice  of  adverse  finding, 
warning letter, untitled letter or other correspondence or written notice from any court or arbitrator or the Applicable Regulatory 
Authorities alleging or asserting non-compliance with any licenses, 

6

 
certificates, approvals, clearances, exemptions, authorizations, permits and supplements or amendments thereto required by any 
such  Health  Care  Laws  (“Regulatory  Authorizations”);  (iii)  possesses  all  Regulatory  Authorizations  required  to  conduct  its 
business  as  currently  conducted  and  such  Regulatory  Authorizations  are  valid  and  in  full  force  and  effect  and  Vir  is  not  in 
violation, in any material respect, of any term of any such Regulatory Authorizations; (iv) has not received notice of any claim, 
action,  suit,  proceeding,  hearing,  enforcement,  investigation,  arbitration  or  other  action  from  any  court  or  arbitrator  or  the 
Applicable Regulatory Authorities or any other third party alleging that any product operation or activity is in material violation 
of any Health Care Laws and has no knowledge that the Applicable Regulatory Authorities or any other third party is considering 
any  such  claim,  litigation,  arbitration,  action,  suit,  investigation  or  proceeding;  (v)  has  not  received  notice  that  any  of  the 
Applicable Regulatory Authorities has taken, is taking or intends to take action to limit, suspend, modify or revoke any material 
Regulatory Authorizations and has no knowledge that any of the Applicable Regulatory Authorities is considering such action; 
(vi)  has  filed,  obtained,  maintained  or  submitted  all  material  reports,  documents,  forms,  notices,  applications,  records,  claims, 
submissions  and  supplements  or  amendments  as  required  by  any  Health  Care  Laws  or  Regulatory  Authorizations  and  that  all 
such  reports,  documents,  forms,  notices,  applications,  records,  claims,  submissions  and  supplements  or  amendments  were 
materially  complete  and  correct  on  the  date  filed  (or  were  materially  corrected  or  supplemented  by  a  subsequent  submission); 
(vii)  is  not  a  party  to  and  does  not  have  any  ongoing  reporting  obligations  pursuant  to  any  corporate  integrity  agreements, 
deferred  prosecution  agreements,  monitoring  agreements,  consent  decrees,  settlement  orders,  plans  of  correction  or  similar 
agreements with or imposed by any Applicable Regulatory Authority; and (viii) along with its employees, officers and directors, 
has not been excluded, disqualified, suspended or debarred from participation in any government health care program or human 
clinical research or, to Vir’s knowledge, subject to a governmental inquiry, investigation, proceeding, or other similar action that 
could reasonably be expected to result in debarment, suspension, disqualification or exclusion. 

2.13

Clinical Trials.  Except for sotrovimab, none of Vir’s product candidates has received marketing approval from 
any Applicable Regulatory Authority.  All clinical and pre-clinical studies and trials conducted by or on behalf of or sponsored by 
Vir,  or  in  which  Vir  has  participated,  with  respect  to  Vir’s  product  candidates,  including  any  such  studies  and  trials  that  are 
described  in  the  SEC  Documents,  or  the  results  of  which  are  referred  to  in  the  SEC  Documents,  as  applicable  (collectively, 
“Company Trials”),  were,  and  if  still  pending  are,  to  Vir’s  knowledge,  being  conducted  in  all  material  respects  in  accordance 
with  all  applicable  Health  Care  Laws  of  the  Applicable  Regulatory  Authorities,  including  the  FDA’s  current  Good  Clinical 
Practices  and  Good  Laboratory  Practices,  standard  medical  and  scientific  research  procedures  and  any  applicable  rules, 
regulations  and  policies  of  the  jurisdiction  in  which  such  trials  and  studies  are  being  conducted.    The  descriptions  in  the  SEC 
Documents of the results of any Company Trials are accurate and complete descriptions in all material respects and fairly present 
the  data  derived  therefrom  as  of  the  date  of  such  SEC  Documents.    Vir  has  no  knowledge  of  any  other  studies  or  trials  not 
described in the SEC Documents, the results of which are inconsistent with or call into question the results described or referred 
to  in  the  SEC  Documents.    Vir  has  not  received  any  written  notices,  correspondence  or  other  communications  from  the 
Applicable  Regulatory  Authorities  or  any  other  governmental  entity  or  any  institutional  review  board  (“IRB”)  or  independent 
ethics committee (“IEC”) requiring or threatening the termination, material modification or suspension of Company Trials, other 
than ordinary course communications with respect to modifications in connection with the design and implementation of such 
studies or trials, and, to Vir’s knowledge, there are no 

7

 
reasonable grounds for the same.  No investigational new drug application or comparable submission filed by or on behalf of Vir 
with the FDA has been terminated or suspended by the FDA or any other Applicable Regulatory Authority.  Vir has obtained (or 
caused to be obtained) informed consent by or on behalf of each human subject who participated in a Company Trial, and Vir has 
obtained (or caused to be obtained) applicable IRB or IEC approvals for each Company Trial.  To Vir’s knowledge, none of the 
Company Trials involved any investigator who has been disqualified as a clinical investigator or has been found by the FDA to 
have engaged in scientific misconduct.

2.14

Absence of Certain Changes.

Except as disclosed in the SEC Documents filed prior to the Execution Date, since September 
30, 2021, no change or event has occurred, except where such change or event has not had, and would not reasonably be expected 
to have, a Material Adverse Effect on Vir. 

(a)

Except as set forth in the SEC Documents filed prior to the Execution Date since September 
30, 2021, Vir has not (i) declared or paid any dividends, or authorized or made any distribution upon or with respect to any class 
or series of its capital stock, or (ii) sold, exchanged or otherwise disposed of any of its material assets or rights.

(b)

(c)

Since  September  30,  2021,  Vir  has  not  admitted  in  writing  its  inability  to  pay  its  debts 
generally as they become due, filed or consented to the filing against it of a petition in bankruptcy or a petition to take advantage 
of any insolvency act, made an assignment for the benefit of creditors, consented to the appointment of a receiver for itself or for 
the whole or any substantial part of its property, or had a petition in bankruptcy filed against it, been adjudicated a bankrupt, or 
filed  a  petition  or  answer  seeking  reorganization  or  arrangement  under  the  federal  bankruptcy  Laws  or  any  other  Laws  of  the 
United States or any other jurisdiction.

company” as defined in the Investment Company Act of 1940, as amended.

otherwise negotiated in respect of, any security (as defined in the Securities Act) that is or will be integrated with the Shares sold 
pursuant to this Agreement in a manner that would require the registration of the Shares under the Securities Act.

it in reliance upon specific exemptions from the registration requirements of United States federal and state securities Laws and 
that  Vir  is  relying  upon  the  truth  and  accuracy  of,  and  the  Foundation’s  compliance  with,  the  representations,  warranties, 
agreements, acknowledgments and understandings of the Foundation set forth herein in order to determine the availability of such 
exemptions and the eligibility of the Foundation to acquire the Shares.

3.5

Accredited  Investor;  Access  to  Information.    The  Foundation  is  an  “accredited  investor”  as  defined  in 
Regulation D under the Securities Act and is knowledgeable, sophisticated and experienced in making, and is qualified to make, 
decisions with respect to investments in shares presenting an investment decision like that involved in the purchase of the Shares.  
The  Foundation  has  been  furnished  with  materials  relating  to  the  offer  and  sale  of  the  Shares  that  have  been  requested  by  the 
Foundation,  including  the  SEC  Documents,  and  the  Foundation  has  had  the  opportunity  to  review  the  SEC  Documents.    The 
Foundation has been afforded the opportunity to 

9

 
ask  questions  of  Vir.    Neither  such  inquiries  nor  any  other  investigation  conducted  by  or  on  behalf  of  the  Foundation  or  its 
representatives or counsel will modify, amend or affect the Foundation’s right to rely on the truth, accuracy and completeness of 
the SEC Documents and Vir’s representations and warranties contained in this Agreement.

3.6

Restricted  Securities.    The  Foundation  understands  that  the  Shares  will  be  characterized  as  “restricted 
securities”  under  the  U.S.  federal  securities  Laws  inasmuch  as  they  are  being  acquired  from  Vir  in  a  private  placement  under 
Section  4(a)(2)  of  the  Securities  Act  and  that  under  such  Laws  and  applicable  regulations  such  Shares  may  be  resold  without 
registration under the Securities Act only in certain limited circumstances.

3.7

Governmental  Review.    The  Foundation  understands  that  no  U.S.  federal  or  state  agency  or  any  other 

Governmental Authority has passed upon or made any recommendation or endorsement of the Shares or an investment therein.

SECTION 4.TRANSFER, RESALE, LEGENDS, REGISTRATION RIGHTS

4.1

Transfer or Resale.  The Foundation understands that:

(a)

the  Shares  have  not  been  and  are  not  being  registered  under  the  Securities  Act  or  any 
applicable  state  securities  Laws  and,  consequently,  the  Foundation  may  have  to  bear  the  risk  of  owning  the  Shares  for  an 
indefinite period of time because the Shares may not be transferred unless (i) the resale of the Shares is registered pursuant to an 
effective registration statement under the Securities Act; (ii) the Foundation has delivered to Vir an opinion of counsel (in form, 
substance  and  scope  customary  for  opinions  of  counsel  in  comparable  transactions)  to  the  effect  that  the  Shares  to  be  sold  or 
transferred may be sold or transferred pursuant to an exemption from such registration; or (iii) the Shares are sold or transferred 
pursuant to Rule 144 under the Securities Act (“Rule 144”); and

(b)

any sale of the Shares made in reliance on Rule 144 may be made only in accordance with the 
terms  of  Rule  144  and,  if  Rule  144  is  not  applicable,  any  resale  of  the  Shares  under  circumstances  in  which  the  seller  (or  the 
Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may 
require compliance with some other exemption under the Securities Act or the rules and regulations of the SEC thereunder.  

4.2

Lock-Up.  The Foundation agrees that it will hold and will not sell any of the Shares (or otherwise make any 
short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect 
as a sale of the Shares) until the one-year anniversary of the Closing Date.  Notwithstanding the foregoing, this Section 4.2 will 
not  preclude  (i)  distributions  of  Shares  to  general  or  limited  partners,  members,  shareholders,  Affiliates  or  wholly-owned 
subsidiaries of the Foundation or any investment fund or other entity controlled or managed by the Foundation; provided, in each 
case, that following any such transfer such Shares will remain subject to the provisions of this Section 4.2; (ii) transfers pursuant 
to  a  bona  fide  third  party  tender  offer  for  all  outstanding  shares  of  Common  Stock,  merger,  consolidation  or  other  similar 
transaction made to all holders of Vir’s securities involving a change of control of Vir (including the entering into any lock-up, 
voting or similar agreement pursuant to which the 

10

 
Foundation  may  agree  to  transfer,  sell,  tender  or  otherwise  dispose  of  Shares  or  other  such  securities  in  connection  with  such 
transaction,  or  vote  any  Shares  or  other  such  securities  in  favor  of  any  such  transaction);  provided,  that  in  the  event  that  such 
tender offer, merger, consolidation or other such transaction is not completed, the Shares shall remain subject to the provisions of 
this Section 4.2; or (iii) sales or transfers of the Shares in connection with the Withdrawal Right (as defined in the Side Letter).

4.3

Legends.    The  Foundation  understands  the  Shares  will  bear  restrictive  legends  in  substantially  the  following 

form (and a stop-transfer order may be placed against transfer of the Shares):

THE SHARES HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, 
OR ANY APPLICABLE STATE SECURITIES LAWS.  THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR 
HYPOTHECATED  IN  THE  ABSENCE  OF  A  REGISTRATION  STATEMENT  IN  EFFECT  WITH  RESPECT  TO  THE 
SECURITIES  UNDER  SUCH  ACT  OR  APPLICABLE  STATE  SECURITIES  LAWS  OR  A  CERTIFICATE  AND/OR  AN 
OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

THE  SALE,  PLEDGE,  HYPOTHECATION  OR  TRANSFER  OF  THESE  SECURITIES  IS  SUBJECT  TO  THE 
TERMS  AND  CONDITIONS  OF  A  STOCK  PURCHASE  AGREEMENT  DATED  JANUARY  12,  2022  BETWEEN  VIR 
BIOTECHNOLOGY, INC. AND THE BILL & MELINDA GATES FOUNDATION.

If such Shares may be transferred pursuant to Section 4.2 (excluding transfers  pursuant  to Section 4.2(i)),  the  Foundation  may 
request that Vir remove, and Vir agrees to authorize and instruct (including by causing any required legal opinion to be provided) 
the removal of any legend from the Shares, if permitted by applicable securities Law, within two (2) Business Days of any such 
request; provided, however, that each party will be responsible for any fees it incurs in connection with such request and removal.

4.4

Registration Rights.  If, following the one-year anniversary of the Closing Date, the Foundation proposes to 
publicly resell the Shares pursuant to Rule 144, and the Foundation in good faith believes it will be unable to sell all of the Shares 
proposed to be sold by it pursuant to Rule 144 without volume or manner-of-sale restrictions, the Foundation shall notify Vir, and 
Vir shall file as promptly as practicable a secondary-only registration statement on Form S-3 (or any successor form to Form S-3) 
promulgated under the Securities Act (which, if Vir is then a “well-known seasoned issuer” (as defined in Rule 405 under the 
Securities Act), shall be filed pursuant to General Instruction I.D of Form S-3 (an “Automatic Shelf Registration Statement”)), 
registering  the  resale  of  such  Shares  (the  “Registrable  Securities”)  (or,  in  the  event  that  Form  S-3  is  not  available  for  the 
registration of the resale of the Registrable Securities, another appropriate form reasonably acceptable to the Foundation) by the 
Foundation (the “Registration Statement”).  Vir shall use commercially reasonable efforts (a) if the Registration Statement is not 
an Automatic Shelf Registration Statement, to cause the Registration Statement to become effective as promptly as practicable; 
(b) to cause the Registration Statement to remain effective until the earlier of (i) the date on which the Foundation has disposed of 
all of the Registrable Securities and (ii) Rule 144 is available for the disposition of all Registrable Securities without volume or 
manner-of-sale 

11

 
restrictions;  (c)  to  undertake  any  additional  actions  reasonably  necessary  to  maintain  the  availability  of,  and  to  facilitate  the 
disposition by the Foundation of the Registrable Securities pursuant to, the Registration Statement; and (d) to obtain any required 
consent under Vir’s Amended and Restated Investors’ Rights Agreement, dated as of November 19, 2017, by and among Vir and 
the investors party thereto or any other agreement to which Vir is a party related to the filing of the Registration Statement.  The 
Foundation  agrees  to  cooperate  with  Vir  as  reasonably  requested  by  Vir  in  connection  with  the  preparation  and  filing  of  the 
Registration Statement, including furnishing to Vir such information regarding itself, the shares of Common Stock held by it and 
the intended method of disposition of the Registrable Securities as shall be reasonably required to effect the registration of such 
Registrable  Securities.    Vir  shall  bear  all  expenses  incurred  in  connection  with  the  performance  of  its  obligations  under  this 
Section 4.4; provided, however, that Vir shall have no obligation to pay for any commissions or transfer taxes of the Foundation.  
Vir’s obligations under this Section 4.4 shall also apply to any shares in the capital of Vir issued or issuable with respect to the 
Registrable Securities as a result of any share split, share dividend, recapitalization, exchange or similar event.

Successors  and  Assigns.    This  Agreement  is  binding  upon  and  inures  to  the  benefit  of  the  parties  and  their 
successors  and  assigns.    Vir  will  not  assign  this  Agreement  or  any  rights  or  obligations  hereunder  without  the  prior  written 
consent of the Foundation, and the Foundation will not assign this Agreement or any rights or obligations hereunder without the 
prior written consent of Vir; provided, however, that the Foundation may assign this Agreement together with all of the 

16

  
  
 
  
  
 
  
  
  
  
  
  
  
  
  
  
 
 
Shares  it  then  owns  (subject  to  Section 4)  to  any  wholly-owned  subsidiary  and  any  such  assignee  may  assign  this  Agreement

reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the 
transactions contemplated hereby.  

7.10

No Strict Construction.    The  language  used  in  this  Agreement  is  deemed  to  be  the  language  chosen  by  the 

parties to express their mutual intent, and no rules of strict construction will be applied against a party.

7.11

Equitable  Relief.    Vir  recognizes  that,  if  it  fails  to  perform  or  discharge  any  of  its  obligations  under  this 
Agreement, any remedy at Law may prove to be inadequate relief to the Foundation.  Vir therefore agrees that the Foundation is 
entitled  to  seek  temporary  and  permanent  injunctive  relief  or  specific  performance  in  any  such  case.    The  Foundation  also 
recognizes that, if it fails to perform or discharge any of its obligations under this Agreement, any remedy at Law may prove to 
be inadequate relief to Vir.  The Foundation therefore agrees that Vir is entitled to seek temporary and permanent injunctive relief 
or specific performance in any such case.

7.12

Expenses.  Vir and the Foundation are each liable for, and will pay, their own expenses incurred in connection 
with  the  negotiation,  preparation,  execution  and  delivery  of  this  Agreement,  including  attorneys’  and  consultants’  fees  and 
expenses.  

7.13

Public Disclosure.  On or within five Business Day of the Execution Date, Vir and the Foundation shall issue a 
joint  press  release  in  a  form  mutually  agreed  to  by  Vir  and  the  Foundation.    In  addition,  if  applicable,  Vir  shall  file  a  Current 
Report on Form 8-K with the SEC within the time period required by such form and including such disclosures as required by 
such form with respect to this Agreement and the transactions contemplated herein, such Current Report on Form 8-K to be in a 
form  mutually  agreed  to  by  Vir  and  the  Foundation.    No  other  written  release,  public  announcement,  disclosure  or  filing 
concerning the purchase of the Shares, the Gates Agreements or the transactions contemplated hereby or thereby shall be issued, 
filed or furnished, as the case may be, by any party without the prior written consent of the other party (which consent shall not 
be unreasonably withheld, conditioned or delayed) and, except as set forth in this Section 8.13, the parties agree to keep the terms 
of the Gates Agreements confidential.  Notwithstanding the foregoing, the parties acknowledge and agree that applicable Law or 
the requirements of a national securities exchange or another similar regulatory body may require either party to file or otherwise 
disclose  a  copy  of  this  Agreement  and/or  the  Side  Letter.    The  party  required  to  make  such  filing  or  otherwise  disclose  shall 
notify the other party and shall provide the other party with 

17

 
at  least  three  (3)  days  to  request  redactions  thereof  prior  to  making  such  filing  or  disclosure.    The  disclosing  party  shall  use 
commercially reasonable efforts to procure confidential treatment of such proposed redactions pursuant to the Securities Act and 
the  Exchange  Act,  in  each  case  as  amended,  and  the  rules,  regulations  and  guidelines  promulgated  thereunder,  or  any  other 
applicable Law or the rules, regulations or guidelines promulgated hereunder; provided that the foregoing shall not prevent the 
party from making such public disclosures as it must make to comply with applicable Law.

THE EXCHANGE

LEASE

This Lease (the “Lease”), dated as of the date set forth in Section 1 of the Summary of Basic Lease Information (the “Summary”), below, is 
made by and between KRE EXCHANGE OWNER LLC, a Delaware limited liability company (“Landlord”), and VIR BIOTECHNOLOGY, INC., a 
Delaware corporation (“Tenant”).

A.  Tenant  presently  subleases  the  same  leased  premises  (as  the  Premises  in  this  Lease)  pursuant  to  that  certain  Sublease  entered  into  as  of  
November 4, 2020, by and between Dropbox, Inc., a Delaware corporation (“Dropbox”) and Tenant (the “Existing Sublease”); Landlord’s predecessor-in-
interest, KR Mission Bay, LLC, a Delaware limited liability company, consented to the Existing Sublease pursuant to a certain Consent to Sublease made 
as of December 21, 2020.

B.  Pursuant  to  the  Existing  Sublease,  Tenant  has  been  working  with  Dropbox  and  Landlord,  as  master  landlord,  to  process  plans  for  the  

construction of alterations to the subleased premises to accomplish a build out of the subleased premises.

C.  Subject to the terms and conditions of this Lease, Tenant desires to lease the Premises directly from Landlord, terminating the Sublease and 

replacing it with this Lease thereby eliminating Dropbox from its role as sublandlord (and the tenant under the primary lease with Landlord).

D.  Effective  as  of  the  Lease  Commencement  Date  (as  defined  below),  this  Lease  supersedes  and  replaces  the  Existing  Sublease,  but  

notwithstanding the replacement of the Existing Sublease with this Lease, Tenant will remain in occupancy of the Premises without interruption.

the Summary (the “Premises”). The outlines of each floor of the Premises are set forth in Exhibit 1.1.1-1 attached hereto. The parties hereto agree that the 
lease  of  the  Premises  is  upon  and  subject  to  the  terms,  covenants  and  conditions  herein  set  forth,  and  Tenant  covenants  as  a  material  part  of  the 
consideration for this Lease to keep and perform each and all of such terms, covenants and conditions by it to be kept and performed and that this Lease is 
made  upon  the  condition  of  such  performance.  The  parties  hereto  hereby  acknowledge  that  the  purpose  of  Exhibit 1.1.1-1 is  to  show  the  approximate 
location of the Premises in the “Building” (as that term is defined in Section 1.1.2 below), only, and such Exhibit is not meant to constitute an agreement, 
representation or warranty as to the construction of the Premises, the precise area thereof or the specific location of the “Common Areas” (as that term is 
defined in Section 1.1.3 below), or the elements thereof or of the accessways to the Premises or the “Project”  (as  that  term  is  defined  in  Section 1.1.2 
below).  Tenant  shall  accept  the  Premises  in  its  presently  existing  “as-is”  condition  and  Landlord  shall  not  be  obligated  to  provide  or  pay  for  any

systems,  fire  sprinkler  and  life-safety  system,  lighting,  air  conditioning  and  heating  systems  and  all  other  building  systems  serving  the  Premises 
(collectively, the “Building Systems”) in good operating condition and repair, and Landlord will be responsible for all repairs at its sole cost (and not as 
part of Operating Expenses) during the six (6) months following the Lease Commencement Date; provided, however, if any failure of the Building Systems 
to be in good operating condition and repair is attributable to Tenant’s construction of improvements pursuant to the Tenant Work Letter, then Tenant shall 
be  solely  liable  for  the  cost  of  any  such  repairs.  Tenant  acknowledges  that  neither  Landlord  nor  any  agent  of  Landlord  has  made  any  representation  or 
warranty regarding the condition of the Premises, the Building or the Project or with respect to the suitability of any of the foregoing for the conduct of 
Tenant’s business, except as specifically set forth in this Lease and the Tenant Work Letter. The Premises shall exclude Common Areas, including without

rules and regulations referred to in Article 5  of  this  Lease,  those  portions  of  the  Project  which  are  provided,  from  time  to  time,  for  use  in  common  by 
Landlord, Tenant and any other tenants of the Project (such areas, together with such other portions of the Project designated by Landlord, in its discretion, 
including  certain  areas  designated  for  the  exclusive  use  of  certain  tenants,  including  Tenant,  or  to  be  shared  by  Landlord  and  certain  tenants,  including 
Tenant, are collectively referred to herein as the “Common Areas”). The Common Areas shall consist of the “Project Common Areas” and the “Building

-6-

 
California.  Tenant’s  use  of  the  Common  Areas  shall  be  subject  to  such  rules,  regulations  and  restrictions  as  Landlord  may  make  from  time  to  time  in 
accordance with Section 5.2 below. Any rules and regulations established by the Landlord for use of the Common Areas shall not unreasonably restrict 
Tenant’s access to or use of the Premises for conduct of its business, nor diminish Tenant’s rights under this Lease. In the event of any conflict between 
such rules and regulations and the terms of this Lease, the latter shall control Landlord reserves the right to close temporarily, make alterations or additions 
to, or change the location of elements of the Project and the Common Areas, provided that, in connection therewith, Landlord shall perform such closures, 
alterations, additions or changes in a commercially reasonable manner and, in connection therewith, shall use commercially reasonable efforts to minimize 
any material interference with Tenant’s use of and access to the Premises.

1.2 Stipulation of Rentable Square Feet of Premises. For purposes of this Lease, the rentable square feet of the Premises and the North Tower 
shall  be  deemed  to  be  as  set  forth  in  Section 2.2  of  the  Summary,  and  the  rentable  square  feet  of  each  of  the  North  Building,  South  Tower  and  South 
Building shall be deemed as set forth in Section 1.1.2 above, none of which shall be subject to remeasurement or adjustment during the Lease Term unless 
the Premises are physically expanded or contracted.

1.3  Adjustment  of  Rentable  Square  Feet  of  Premises.  Landlord  acknowledges  that  the  installation  of  the  Mechanical  Shaft  described  in 
Section 2.2(e) of the Tenant Work Letter will result in a reduction of approximately 669 rentable square feet of Premises, and as a consequence thereof, 
Landlord will give to Tenant a credit against Base Rent for month 8 of the Lease Term in the amount of $693,666.03 as full and complete compensation to 
Tenant for the loss of such rentable square footage (and in exchange for Tenant enjoying such rent credit, Tenant will nevertheless pay Base Rent under this 
Lease without any reduction or adjustment in rentable square footage of the Premises).

1.4 Right of First Refusal. Landlord hereby grants to the Tenant named in the Summary (the “Original Tenant”) and any Permitted Assignee a 
right of first refusal with respect to the entire seventh (7th) floor of the Building as more particularly described on Exhibit 1.4 (the “First Refusal Space”). 
Notwithstanding the foregoing, such first refusal right of Tenant shall commence only following the expiration or earlier termination of the Existing Lease 
with Dropbox of the First Refusal Space, and such right of first refusal shall be subordinate to all rights of Dropbox which are set forth in the Existing 
Lease as of the date hereof with respect to such First Refusal Space. Tenant’s right of first refusal shall not be applicable after the third (3rd) anniversary of 
the Lease Commencement Date (which three (3) year period may be referred to as the “First Refusal Period”). Tenant’s right of first refusal shall be on 
the terms and conditions set forth in this Section 1.4.

1.4.1 Procedure for Offer. Prior to entering any lease for all or any portion of the First Refusal Space during the First Refusal Period, 
Landlord shall provide a written notice to Tenant (the “First Refusal Notice”), offering to lease to Tenant the applicable portion of the First Refusal Space. 
The First Refusal Notice shall describe the terms on which the other prospective tenant may lease the First Refusal Space, including setting forth the rent 
and the other material economic terms upon which Landlord is willing to lease such space to such other tenant.

1.4.2 Procedure for Acceptance. If Tenant wishes to exercise Tenant’s right of first refusal with respect to the space described in the 
First Refusal Notice, then within seven (7) business days after delivery of the First Refusal Notice to Tenant, Tenant shall deliver notice to Landlord of 
Tenant’s election to exercise its right of first refusal with respect to the entire space described in the First Refusal Notice on the terms contained in such 
notice. If Tenant does not so notify Landlord within the seven (7) business day period, then Landlord shall be free to lease the space described in the First 
Refusal  Notice  to  the  other  tenant  or  any  affiliate  thereof  on  generally  the  same  terms  as  contained  in  the  First  Refusal  Notice,  provided  that,  prior  to 
entering into a lease of such space on material economic terms that are more than seven and one-half percent (7.5%) more favorable to the tenant than the 
Base Rent set forth in the First Refusal Notice, Landlord shall first deliver another First Refusal Notice to Tenant offering such space to Tenant on such 
reduced terms. Tenant shall respond to any such “re-offer” within five (5) business days after delivery of such “re-offer” notice. Notwithstanding anything 
to the contrary contained herein, Tenant must elect to exercise its right of first refusal, if at all, with respect to all of the space covered by the First Refusal 
Notice, and Tenant may not elect to lease only a portion thereof. The First Refusal Space shall be leased by Tenant on all of the terms and conditions of this 
Lease except as set forth in the First Refusal Notice and this Section 1.3.

in the First Refusal Notice.

1.4.3 Construction In First Refusal Space. Tenant shall take the First Refusal Space in its “as is” condition unless otherwise set forth 

-7-

 
1.4.4 Amendment to Lease. If Tenant timely exercises Tenant’s right to lease the First Refusal Space as set forth herein, then the First 
Refusal Space shall be added to the Premises on the terms set forth herein (except that the term of any such lease shall be appropriately adjusted to be co-
terminous with the Lease Term of this Lease) and, at the election of Landlord or Tenant, the parties shall promptly thereafter execute an amendment to this 
Lease for such First Refusal Space (but the execution of such amendment shall not be required for the lease of the First Refusal Space to become effective). 
Tenant shall commence payment of Rent for the First Refusal Space, and the term of the First Refusal Space shall commence upon the date of delivery of 
the First Refusal Space to Tenant in the condition required by the First Refusal Notice (the “First Refusal Commencement Date”) and terminate on the 
Lease Expiration Date.

1.4.5 Termination of Right of First Refusal. The rights contained in this Section 1.2 shall be personal to the Original Tenant (and any 
Permitted Assignee) and may only be exercised by the Original Tenant (and not any other assignee, sublessee or other transferee of the Original Tenant’s 
interest in this Lease other than a Permitted Assignee) if the Original Tenant or a Permitted Assignee occupies the entire Premises. Except as expressly set 
forth  in  this  Section  1.4,  the  right  of  first  refusal  granted  herein  shall  terminate  as  to  a  particular  First  Refusal  Notice  (and  the  First  Refusal  Space 
applicable thereto) upon the failure by Tenant to exercise its right of first refusal with respect to such First Refusal Space as offered by Landlord. Tenant 
shall not have the right to lease First Refusal Space, as provided in this Section 1.4, if, as of the date of the attempted exercise of any right of first refusal by 
Tenant,  or  as  of  the  scheduled  date  of  delivery  of  such  First  Refusal  Space  to  Tenant,  Tenant  is  in  default  under  this  Lease,  after  the  expiration  of  any 
applicable notice and cure period, or Tenant has previously been in default, after the expiration of any applicable notice and cure period, under this Lease 
more than once during the First Refusal Period.

1.5 Condition Precedent. Tenant acknowledges and agrees that this Lease is subject to the following express conditions precedent: (i) Landlord 
consummating an amendment with Dropbox of its lease covering the entire Project (other than the Retail Space) so as to eliminate floors eight (8) through 
twelve (12) of the North Tower therefrom (such that Landlord has recaptured such floors) and converting the Project from a single tenant project to a multi-
tenant  project  (which  amendment  may  be  referred  to  as  the  “Dropbox Amendment”)  and  (ii)  the  termination  of  the  Existing  Sublease.  The  terms  and 
conditions of the Dropbox Amendment shall be satisfactory to Landlord in its sole and absolute discretion.

1.6 Meeting Rooms. So long as Tenant is not in default hereunder beyond applicable notice and cure periods, Landlord shall use commercially 
reasonable efforts to make available Common Area meeting rooms, if any, in the Project (collectively, the “Common Area Meeting Spaces”) for Tenant’s 
use for business meetings and special events. Such use shall be subject to availability, on a first come, first serve basis, and shall be upon and subject to 
such rules, regulations and limitations as Landlord may reasonably establish from time to time for use of the Common Area Meeting Spaces (including, 
without limitation, as to scheduling, catering, hours of use, the provision and cost of janitorial and security services, facility and equipment usage charges, 
reimbursement of Landlord’s costs and expenses reasonably incurred in facilitating such use by Tenant, and cleaning/security deposits); provided, however, 
that (a) Landlord shall use commercially reasonable efforts to give Tenant equitable access with other tenants to the Common Area Meeting Rooms and, 
accordingly, not allow other tenants of the Project to block-book the Common Area Meeting Rooms (i.e. reserve spaces for more than three (3) business 
days in a row unless connected to a special event); and (b) once Tenant has properly booked the use of the Common Area Meeting Spaces for a particular 
date and time, such booking may not be cancelled without Tenant’s prior consent. If requested by Tenant, Landlord will provide a schedule of available 
dates and times for use of the Common Area Meeting Spaces. In connection with its use of the Common Area Meeting Spaces, Tenant shall enter into 
Landlord’s then-current form of agreement for the use of such spaces. Tenant use of the Common Area Meeting Spaces shall be at Tenant’s sole risk and 
Tenant acknowledges and agrees that Landlord shall have no liability whatsoever to Tenant, its employees and/or visitors for personal injury or property 
damage  or  theft  relating  to  or  connected  with  any  use  of  the  Common  Area  Meeting  Spaces  by  Tenant  or  its  employees  and/or  visitors.  Landlord 
specifically reserves the right to change the location, size, configuration, design, layout and all other aspects of the Common Area Meeting Spaces at any 
time and Tenant acknowledges and agrees that Landlord may from time to time, on a temporary basis, or on a permanent basis, close, close-off or restrict 
access to the Common Area Meeting Spaces. The right to use the Common Area Meeting Spaces may not be assigned or in any other way transferred to 
any other person or entity. Tenant acknowledges that the waiver of claims and indemnification provided in this Lease apply to the use of the Common Area 
Meeting Spaces by Tenant. Notwithstanding anything to the contrary contained in this Lease, Tenant acknowledges that, as of the date of this Lease, the 
Project does not have any Common Area Meeting Rooms.

2. LEASE TERM

2.1 Lease Term. The terms and provisions of this Lease shall be effective as of the date of this Lease. The term of this Lease (the “Lease Term”) 
shall be as set forth in Section 3.1 of the Summary, shall commence on the date set forth in Section 3.2  of  the  Summary  (the  “Lease Commencement 
Date”), and shall terminate on the date set forth in Section 3.4 of the Summary (the “Lease Expiration Date”) unless this Lease is sooner terminated as 
hereinafter provided. For purposes of this Lease, the term “Lease Year” shall mean the consecutive twelve (12) month period following and including the 
Lease Commencement Date and each subsequent twelve (12) month period during the Lease Term; provided, however, if the Lease Commencement Date 
is other than the first (1st) day of a calendar month, “Month 1” will include the first full calendar month following the Lease Commencement Date plus any 
partial calendar month following the Lease Commencement Date. In the event Month 1 includes any partial calendar month, Tenant shall pay the prorated 
amount of Monthly Base Rent for such partial calendar month pursuant to Article 3 in addition to the Monthly Base Rent for the ninth (9th) full calendar 
month of the Lease Term (and to the extent that Month 1 is included as part of the Abatement Period, any such partial calendar month shall be excluded 
from the Abatement Period). At any time during the Lease Term, Landlord may deliver to Tenant a notice in the form as set forth in Exhibit 2.1, attached 
hereto,  as  a  confirmation  only  of  the  information  set  forth  therein,  which  Tenant  shall  execute  (or  provide  factual  correction  to)  and  return  to  Landlord 
within ten (10) business days of receipt thereof, but execution of such instrument shall not be a condition to Lease commencement or Tenant’s obligations 
hereunder.

3. BASE RENT

3.1 Payment of Rent. Tenant shall pay, without prior notice or demand, to Landlord’s agent at the management office of the Project or at such 
place as Landlord may from time to time designate in writing, by a check for currency which, at the time of payment, is legal tender for private or public 
debts in the United States of America or pursuant to wire or electronic payment instructions provided by Landlord, base rent (“Base Rent”) as set forth in 
Section 4 of the Summary, payable in equal monthly installments as set forth in Section 4 of the Summary, in advance, on or before the first day of each 
and every calendar month during the Lease Term, without any setoff or deduction whatsoever, except as may be expressly set forth in this Lease. Base Rent 
for  the  first  full  month  of  the  Lease  Term  shall  be  paid  at  the  time  of  Tenant’s  execution  of  this  Lease.  If  any  Rent  payment  date  (including  the  Lease 
Commencement Date) falls on a day of the month other than the first day of such month or if any payment of Rent is for a period which is shorter than one 
month, the Rent for any fractional month shall accrue on a daily basis for the period from the date such payment is due to the end of such calendar month or 
to the end of the Lease Term at a rate per day which is equal to 1/365 of the applicable annual Rent. All other payments or adjustments required to be made 
under the terms of this Lease that require proration on a time basis shall be prorated on the same basis. Base Rent and Additional Rent shall together be 
denominated “Rent”. Without limiting the foregoing, Tenant’s obligation to pay Rent shall be absolute, unconditional and independent of any Landlord 
covenants and shall not be discharged or otherwise affected by any law or regulation now or hereafter applicable to the Premises, or any other restriction on 
Tenant’s use, or (except as expressly provided herein) any casualty or taking, or any failure by Landlord to perform any covenant contained herein, or any 
other occurrence; and Tenant assumes the risk of the foregoing and waives all rights now or hereafter existing to terminate or cancel this Lease or quit or 
surrender the Premises or any part thereof (absent a judicial order providing for such termination or cancellation), or to assert any defense in the nature of 
constructive eviction (in which Tenant asserts that its use and enjoyment of the Premises has been disrupted due to any entry by Landlord of the Premises in 
accordance with Section 27.2 of this Lease, any renovation of the Project or any casualty or condemnation affecting the Project) to any action seeking to 
recover rent (except to the extent Tenant’s obligation to pay Base Rent may be expressly abated pursuant to Articles 11 and 13  of  this  Lease).  Tenant’s 
covenants contained herein are independent and not dependent, and Tenant hereby waives the benefit of any statute or judicial law to the contrary.

3.2 Rents from Real Property. Landlord and Tenant hereby agree that it is their intent that all Base Rent, Additional Rent and other rent and 
charges payable to the Landlord under this Lease (hereinafter individually and collectively referred to as “Rent”) shall qualify as “rents from real property” 
within  the  meaning  of  Section  856(d)  of  the  Internal  Revenue  Code  of  1986,  as  amended  (the  “Code”),  and  the  Department  of  the  U.S.  Treasury 
Regulations promulgated thereunder (the “Regulations”). Should the Code or the Regulations, or interpretations thereof by the Internal Revenue Service 
contained in revenue rulings or other similar public pronouncements, be changed so that any Rent no longer so qualifies as “rent from real property” for 
purposes  of  Section  856(d)  of  the  Code  and  the  Regulations  promulgated  thereunder,  such  Rent  shall  be  adjusted  in  such  manner  as  the  Landlord  may 
require so that it will so 

-9-

 
qualify; provided, however, that any adjustments required pursuant to this Section 7.3 shall be made so as to produce the equivalent (in economic terms) 
Rent as payable prior to such adjustment.

4. ADDITIONAL RENT

4.1 General Terms. In addition to paying the Base Rent specified in Article 3 of this Lease, Tenant shall pay “Tenant’s Share” of the annual 
“Direct Expenses” as those terms are defined in Sections 4.2.6 and 4.2.2 of this Lease, respectively. Such payments by Tenant, together with any and all 
other  amounts  payable  by  Tenant  to  Landlord  pursuant  to  the  terms  of  this  Lease  other  than  Base  Rent,  are  hereinafter  collectively  referred  to  as  the 
“Additional Rent”. All amounts due under this Article 4 as Additional Rent shall be payable for the same periods and in the same manner as the Base 
Rent. Without limitation on other obligations of Tenant which survive the expiration of the Lease Term, the obligations of Tenant to pay the Additional 
Rent provided for in this Article 4 shall survive the expiration of the Lease Term, subject to Section 4.4.1.

4.2 Definitions of Key Terms Relating to Additional Rent. As used in this Article 4, the following terms shall have the meanings hereinafter 

set forth:

4.2.1 Intentionally Omitted.

4.2.2 “Direct Expenses” shall mean “Operating Expenses” and “Tax Expenses”.

4.2.3 “Expense Year” shall mean each calendar year in which any portion of the Lease Term falls, through and including the calendar 
year in which the Lease Term expires, provided that Landlord, upon notice to Tenant, may change the Expense Year from time to time to any other twelve 
(12) consecutive month period, and, in the event of any such change, Tenant’s Share of Direct Expenses shall be equitably adjusted for any Expense Year 
involved in any such change.

4.2.4 “Operating Expenses” shall mean all expenses, costs and amounts of every kind and nature which Landlord pays or accrues 
during any Expense Year because of or in connection with the ownership, management, maintenance, security, repair, replacement, restoration or operation 
of the Project or any portion thereof (including, without limitation, any amenities (e.g., fitness center) available to tenants within the Building or Project). 
Without limiting the generality of the foregoing, Operating Expenses shall specifically include any and all of the following: (i) the cost of supplying all 
utilities, the cost of operating, repairing, maintaining, and renovating the utility, telephone, mechanical, sanitary, storm drainage, and elevator systems, and 
the  cost  of  maintenance  and  service  contracts  in  connection  therewith;  (ii)  the  cost  of  licenses,  certificates,  permits  and  inspections  and  the  cost  of 
contesting any governmental enactments which may affect Operating Expenses, and the costs incurred in connection with providing a shuttle service, if 
any, and the costs incurred in connection with any federal, state or municipal governmentally mandated transportation demand management program or 
similar  program;  (iii)  the  cost  of  all  insurance  carried  by  Landlord  in  connection  with  the  Project  (including,  without  limitation,  commercial  general 
liability  insurance,  physical  damage  insurance  covering  damage  or  other  loss  caused  by  fire,  earthquake,  flood  and  other  water  damage,  explosion, 
vandalism and malicious mischief, theft or other casualty, rental interruption insurance, and such insurance as may be required by any lessor under any 
present or future ground or underlying lease of the Building or Project or any holder of a mortgage, trust deed or other encumbrance now or hereafter in 
force against the Building or Project or any portion thereof or as required pursuant to the Underlying Documents); (iv) the cost of landscaping, re-lamping, 
and all supplies, tools, equipment and materials used in the operation, repair and maintenance of the Project, or any portion thereof; (v) all costs incurred in 
connection with the Parking Facilities; (vi) fees and other costs, including management, consulting fees, legal fees and accounting fees, of all contractors 
and  consultants  in  connection  with  the  management,  operation,  maintenance  and  repair  of  the  Project;  (vii)  payments  under  any  equipment  rental 
agreements and the fair rental value of any management space; (viii) wages, salaries and other compensation and benefits, including taxes levied thereon, 
of all persons engaged in the operation, maintenance and security of the Project; (ix) costs under any instrument pertaining to the sharing of costs by the 
Project; (x) operation, repair, maintenance and replacement of all systems and equipment and components thereof of the Project; (xi) the cost of janitorial, 
alarm, security and other services, replacement of wall and floor coverings, ceiling tiles and fixtures in Common Areas, maintenance and replacement of 
curbs and walkways, repair to roofs and re-roofing; (xii) amortization (including reasonable interest on the unamortized cost) over such period as Landlord 
shall reasonably determine, of the cost of acquiring or the rental expense of personal property used in the maintenance, operation and repair of the Project 
or any portion thereof; (xiii) the cost of capital improvements, capital repairs or other capital costs 

-10-

 
incurred in connection with the Project (A) which are intended to reduce expenses in the operation or maintenance of the Project, or any portion thereof, or 
to reduce current or future Operating Expenses or to enhance the safety or security of the Project or its occupants, (B) that are required to comply with 
present  or  anticipated  mandatory  energy  conservation  programs,  (C)  which  are  replacements  or  modifications  of  nonstructural  items  located  in  the 
Common Areas required to keep the Common Areas in the same good order or condition as on the Lease Commencement Date, or (D) that are required 
under  any  federal,  state  or  municipal  governmental  law  or  regulation  that  was  not  in  force  or  effect  as  of  the  Lease  Commencement  Date;  provided, 
however, that the costs of any capital improvement shall be amortized (including with interest at the Amortization Interest Rate on the amortized cost as 
reasonably determined by Landlord) over the useful life of the capital item in question, as Landlord shall reasonably determine, in a manner consistent with 
the practices of landlords of “Comparable Buildings” (i.e., similar buildings located with the area depicted in Exhibit 4.2.4 attached hereto) and otherwise 
in  accordance  with  sound  real  estate  management  and  accounting  practices  or,  with  respect  to  cost  saving  capital  expenditures,  their  recovery/payback 
period as Landlord shall reasonably determine, in a manner consist with the practices of landlords of Comparable Buildings and otherwise in accordance 
with sound real estate management and accounting practices, consistently applied; (xiv) costs, fees, charges or assessments imposed by, or resulting from 
any mandate imposed on Landlord by, any federal, state or municipal government for fire and police protection, trash removal, community services, or 
other services which do not constitute “Tax Expenses” (as that term is defined in Section 4.2.5 below); (xv) cost of tenant relation programs reasonably 
established by Landlord, and (xvi) payments under any Underlying Documents (as that term is defined in Article 24 below). In the event that Landlord or 
Landlord’s managers or agents perform services for the benefit of the Building off-site which would otherwise be performed on-site (e.g., accounting), the 
cost  of  such  services  shall  be  reasonably  allocated  among  the  properties  benefitting  from  such  service  and  shall  be  included  in  Operating  Expenses. 
Notwithstanding the foregoing, for purposes of this Lease, Operating Expenses shall not, however, include:

(a) costs, including legal fees, space planners’ fees, advertising and promotional expenses, and brokerage fees incurred in 
connection with the original construction or development, or original or future leasing of the Project, and costs, including permit, license and inspection 
costs,  incurred  with  respect  to  the  installation  of  tenant  improvements  made  for  tenants  or  incurred  in  renovating  or  otherwise  improving,  decorating, 
painting or redecorating vacant space for tenants of the Project (excluding, however, such costs relating to any Common Areas), and any costs or expenses 
incurred in connection with the relocation of any tenants of the Building or Project;

other debt costs, if any, penalties and interest, and costs of capital improvements (as distinguished from non-capital repairs or replacements);

(b) except as set forth in items (xii), (xiii), and (xiv) above, depreciation, interest and principal payments on mortgages and 

(c) costs for which Landlord is reimbursed by any tenant or occupant of the Project (other than as Direct Expenses) or by 
insurance by its carrier or any tenant’s carrier or by anyone else (or would have been reimbursed if Landlord had carried the insurance Landlord is required 
to carry pursuant to this Lease or enforced its rights against such third-party, as applicable), and electric power costs for which any tenant directly contracts 
with the local public service company or pays directly to Landlord;

(d) any bad debt loss, rent loss, or reserves for bad debts or rent loss;

(e) costs associated with the operation of the business of the partnership or entity which constitutes Landlord, as the same 
are distinguished from the costs of operation of the Project (which shall specifically include, but not be limited to, accounting costs associated with the 
operation  of  the  Project).  Costs  associated  with  the  operation  of  the  business  of  the  partnership  or  entity  which  constitutes  Landlord  include  costs  of 
partnership accounting and legal matters, costs of defending any lawsuits with any mortgagee (except as the actions of Tenant may be in issue), costs of 
selling, syndicating, financing, mortgaging or hypothecating the Project or any of Landlord’s interest in the Project, and costs incurred in connection with 
any disputes between Landlord and its employees, between Landlord and Project management, or between Landlord and other tenants or occupants;

(f) the wages and benefits of any employee who does not devote substantially all of his or her employed time to the Project 
unless  such  wages  and  benefits  are  prorated  to  reflect  time  spent  on  operating  and  managing  the  Project  vis-a-vis  time  spent  on  matters  unrelated  to 
operating  and  managing  the  Project;  provided,  that  in  no  event  shall  Operating  Expenses  for  purposes  of  this  Lease  include  wages  and/or  benefits 
attributable to personnel above the level of Project manager;

-11-

 
(g) amount paid as ground rental for the Project by Landlord;

(h) except for a property management fee (and subject to the exclusion in item (q) below), overhead and profit increment 
paid to Landlord or to subsidiaries or affiliates of Landlord for services in the Project to the extent the same exceeds the costs of such services rendered by 
qualified, first-class unaffiliated third parties on a competitive basis;

that any compensation paid to any concierge at the Project shall be includable as an Operating Expense;

(i) any compensation paid to clerks, attendants or other persons in commercial concessions operated by Landlord, provided 

Landlord (other than as Direct Expenses) or which Landlord provides selectively to one or more tenants (other than Tenant) without reimbursement;

(j)  all  items  and  services  for  which  Tenant  or  any  other  tenant  in  the  Project  reimburses  (or  is  obligated  to  reimburse) 

(k) rent for any office space occupied by Project management personnel to the extent the size or rental rate of such office 
space exceeds the size or fair market rental value of office space occupied by management personnel of Comparable Buildings, with adjustment where 
appropriate for the size of the applicable project;

(l)  costs  incurred  to  comply  with  laws  relating  to  the  removal  of  Hazardous  Materials  (other  than  Hazardous  Materials 
typically  found  in  comparable  buildings,  such  as  recyclable  materials  and  typical  construction  materials,  and  costs  to  comply  with  the  operation  and 
maintenance plan, if any);

(m) Landlord’s general overhead expenses not related to the Project;

(n) legal fees, accountants’ fees (other than normal bookkeeping expenses) and other expenses incurred in connection with 
disputes of tenants or other occupants of the Project or associated with the enforcement of the terms of any leases with tenants or the defense of Landlord’s 
title to or interest in the Project or any part thereof;

(o) any reserve funds;

arising from the gross negligence or willful misconduct of Landlord, or its agents, employees, vendors, contractors, or providers of materials or services;

(p) costs arising due to a violation by Landlord or any other tenant of the Project of the terms and condition of a lease, or 

Rent (adjusted and grossed up during any period in which Tenant’s Base Rent (or portion thereof) is abated);

(q) any management fee, of which Tenant’s Share in a particular Expense Year exceeds three percent (3%) of Tenant’s Base 

any tenant of the Project;

(r) advertising and promotional expenditures, and costs of signs in or on the Project identifying the owner of the Project or 

(s) fees, penalties and interest resulting from Landlord’s failure to pay any Operating Expense as and when due;

(t) costs to comply with Applicable Laws where such violation of Applicable Laws existed as of the date the Project was 

originally built (i.e., 2018); and

(u) any costs expressly excluded from Operating Expenses elsewhere in this Lease. 

If  Landlord  is  not  furnishing  any  particular  work  or  service  (the  cost  of  which,  if  performed  by  Landlord,  would  be  included  in  Operating 
Expenses) to a tenant who has undertaken to perform such work or service in lieu of the performance thereof by Landlord, Operating Expenses shall be 
deemed  to  be  increased  by  an  amount  equal  to  the  additional  Operating  Expenses  which  would  reasonably  have  been  incurred  during  such  period  by 
Landlord if it had at its own expense furnished such work or service to such tenant. If the Project is not at least one hundred percent (100%) occupied 
during all or a portion of any Expense Year, Landlord shall make an appropriate adjustment to the 

-12-

 
components of Operating Expenses for such year to determine the amount of Operating Expenses that would have been incurred had the Project been one 
hundred percent (100%) occupied; and the amount so determined shall be deemed to have been the amount of Operating Expenses for such year. Landlord 
and Tenant acknowledge and agree that the intention of this Article 4 is to facilitate Landlord’s recovery of Operating Expenses as opposed to generating a 
profit center.

4.2.5 Taxes.

4.2.5.1 “Tax Expenses” shall mean all federal, state, county, or local governmental or municipal taxes, fees, charges or other 
impositions  of  every  kind  and  nature,  whether  general,  special,  ordinary  or  extraordinary  (including,  without  limitation,  real  estate  taxes,  general  and 
special assessments, transit taxes, payments in lieu of taxes, business improvement district charges, leasehold taxes or taxes based upon the receipt of rent, 
including gross receipts or sales taxes applicable to the receipt of rent (inclusive of any so-called “Proposition C” taxes), unless required to be paid by 
Tenant, personal property taxes imposed upon the fixtures, machinery, equipment, apparatus, systems and equipment, appurtenances, furniture and other 
personal  property  used  by  Landlord  in  connection  with  the  Project,  or  any  portion  thereof),  which  shall  be  paid  or  accrued  during  any  Expense  Year 
(without regard to any different fiscal year used by such governmental or municipal authority) because of or in connection with the ownership, leasing and 
operation  of  the  Project,  or  any  portion  thereof  (including,  without  limitation,  the  land  upon  which  the  Building,  including  the  Parking  Facilities,  are 
located).

4.2.5.2 Tax Expenses shall include, without limitation: (i) Any tax on the rent, right to rent or other income from the Project, 
or any portion thereof, or as against the business of leasing the Project, or any portion thereof; (ii) any assessment, tax, fee, levy or charge in addition to, or 
in  substitution,  partially  or  totally,  of  any  assessment,  tax,  fee,  levy  or  charge  previously  included  within  the  definition  of  real  property  tax,  it  being 
acknowledged by Tenant and Landlord that Proposition 13 was adopted by the voters of the State of California in the June 1978 election (“Proposition 
13”) and that assessments, taxes, fees, levies and charges may be imposed by governmental agencies for such services as fire protection, street, sidewalk 
and  road  maintenance,  refuse  removal  and  for  other  governmental  services  formerly  provided  without  charge  to  property  owners  or  occupants,  and,  in 
further recognition of the decrease in the level and quality of governmental services and amenities as a result of Proposition 13, Tax Expenses shall also 
include any governmental or private assessments or the Project’s contribution towards a governmental or private cost-sharing agreement for the purpose of 
augmenting or improving the quality of services and amenities normally provided by governmental agencies; (iii) any assessment, tax, fee, levy, or charge 
allocable  to  or  measured  by  the  area  of  the  Premises  or  the  Rent  payable  hereunder,  including,  without  limitation,  any  business  or  gross  income  tax  or 
excise tax with respect to the receipt of such rent, or upon or with respect to the possession, leasing, operating, management, maintenance, alteration, repair, 
use or occupancy by Tenant of the Premises, or any portion thereof; and (iv) any assessment, tax, fee, levy or charge, upon this transaction or any document 
to which Tenant is a party, creating or transferring an interest or an estate in the Premises or the improvements thereon; and (v) all of the real estate taxes 
and  assessments  imposed  upon  or  with  respect  to  the  buildings  and  all  of  the  real  estate  taxes  and  assessments  imposed  on  the  land  and  improvements 
comprising the Project, including any such taxes or assessments relating to the Underlying Documents or Mission Bay Requirements. If at any time during 
the Lease Term there shall be assessed on Landlord, in addition to or lieu of the whole or any part of the ad valorem tax on real or personal property, a 
capital levy or other tax on the gross rents or other measures of building operations, or a governmental income, franchise, excise or similar tax, assessment, 
levy, charge or fee measured by or based, in whole or in part, upon building valuation, gross rents or other measures of building operations or benefits of 
governmental services furnished to the Building, then any and all of such taxes, assessments, levies, charges and fees, to the extent so measured or based, 
shall be included within the term Tax Expenses, but only to the extent that the same would be payable if the Building and Land were the only property of 
Landlord.

4.2.5.3  Any  costs  and  expenses  (including,  without  limitation,  reasonable  attorneys’  and  consultants’  fees)  incurred  in 
attempting to protest, reduce or minimize Tax Expenses in good faith shall be included in Tax Expenses in the Expense Year such expenses are incurred. 
Tax refunds shall be credited against Tax Expenses and refunded to Tenant regardless of when received, based on the Expense Year to which the refund is 
applicable, provided that in no event shall the amount to be refunded to Tenant for any such Expense Year exceed the total amount paid by Tenant as on 
account  of  Tax  Expenses  under  this  Article  4  for  such  Expense  Year.  The  foregoing  sentence  shall  survive  the  expiration  or  earlier  termination  of  this 
Lease.  If  Tax  Expenses  for  any  period  during  the  Lease  Term  or  any  extension  thereof  are  increased  after  payment  thereof  for  any  reason,  including, 
without limitation, escape 

-13-

 
assessment or error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord Tenant’s Share of any such increased 
Tax Expenses within thirty (30) days after Landlord’s request, together with supporting documentation of such increase. Notwithstanding anything to the 
contrary contained in this Section 4.2.5,  there  shall  be  excluded  from  Tax  Expenses  (i)  all  excess  profits  taxes,  franchise  taxes,  gift  taxes,  capital  stock 
taxes, inheritance and succession taxes, estate taxes, documentary transfer taxes (incurred in connection with the sale or financing of the Project or any 
portion thereof, but any changes in Tax Expenses following a reassessment of the Project relating to a change in ownership shall continue to be includable 
in Tax Expenses), federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net income (as opposed to rents, receipts 
or income attributable to operations at the Project), (ii) any items included as Operating Expenses, (iii) any items paid by Tenant under Section 4.5 of this 
Lease, (iv) tax penalties, fees or interest incurred as a result of Landlord’s failure to make payments and/or to file any tax or informational returns when 
due, and (v) any assessments on real property or improvements located outside of the Project. For purposes of calculating Tax Expenses for the Project for 
any Expense Year, if such Tax Expenses do not reflect an assessment (or Tax Expenses) for a one hundred percent (100%) leased, completed and occupied 
project (such that existing or future leasing, improvements and/or occupancy may result in an increased assessment and/or increased Tax Expenses) with 
the Project being one hundred percent (100%) occupied by tenants paying full rent, such Tax Expenses shall adjusted, on a basis consistent with sound real 
estate accounting principles, to reflect an assessment for (and Tax Expenses for) a one hundred percent (100%) leased, completed and occupied project with 
the Project being one hundred percent (100%) occupied by tenants paying full rent.

Tax Expenses and the filing of any such proceeding by Tenant without Landlord’s consent shall constitute a Default by Tenant.

4.2.5.4 Notwithstanding anything to the contrary set forth in this Lease, only Landlord may institute proceedings to reduce 

4.2.6 “Tenant’s Share” is based upon the ratio that the rentable square feet of the Premises bears to the rentable square feet of the 
Building and initially shall mean the percentage set forth in Section 7 of the Summary, subject to adjustment in the event that Tenant physically expands or 
contracts  the  Premises  within  the  Building.  For  the  avoidance  of  doubt,  and  notwithstanding  anything  to  the  contrary  herein,  no  remeasurement  of  the 
Building or Project shall result in an increase in the Base Rent payable under this Lease.

4.3 Allocation of Direct Expenses.

4.3.1  Method  of  Allocation.  The  parties  acknowledge  that  the  Project  contains  four  (4)  sub-  buildings  or  sectors  (i.e.,  the  North 
Tower, the North Building, the South Tower and the South Building, each a sub- building herein and together comprising the entire Building) and that the 
costs and expenses incurred in connection with the Project (i.e., the Direct Expenses) should be equitably allocated among those sub-buildings comprising 
the  Project  and  shared  by  the  tenants  of  each  of  those  sub-buildings.  Accordingly,  as  set  forth  in  Section 4.2  above,  Direct  Expenses  (which  consist  of 
Operating Expenses and Tax Expenses) attributable only to a particular sub-building or sub-buildings, but not the Project generally, shall be included in 
Direct  Expenses  for  such  sub-building  or  sub-  buildings,  but  excluded  from  Direct  Expenses  for  any  other  sub-buildings,  and  Direct  Expenses  that  are 
attributable  to  the  Project  as  a  whole  shall  be  allocated  among  the  Building  pro  rata  based  on  the  relative  rentable  square  footages  of  each  of  the  sub-
buildings as compared to the rentable square footage of the entire Building in the aggregate. Accordingly, such portion of Direct Expenses allocated to the 
tenants  of  the  sub-building  shall  include  all  Direct  Expenses  attributable  solely  to  the  sub-building  and  an  equitable  portion  of  the  Direct  Expenses 
attributable  to  the  entire  Building  as  a  whole.  Further,  Landlord  shall  have  the  right,  from  time  to  time,  to  allocate  equitably  some  or  all  of  the  Direct 
Expenses for a sub-building or the Project among different portions or occupants of the sub-building or Project, in Landlord’s reasonable discretion, in a 
manner reflecting commercially reasonable cost pools for such Direct Expenses so allocated. The Direct Expenses within each cost pool shall be allocated 
and charged to the tenants within such cost pool in an equitable manner.

4.3.2 Cost Pools.  The  parties  acknowledge  that  certain  of  the  costs  and  expenses  incurred  in  connection  with  the  Project  (i.e.,  the 
Direct Expenses) should be separately allocated to the office space and the Retail Space. Direct Expenses shall be allocated between the office space and 
Retail Space (each, a “Cost Pool”) based on the estimated benefit derived by the space which is the subject of the Cost Pool, and such allocations shall be 
reasonably determined by Landlord. Accordingly, Direct Expenses shall be charged to the Retail Space and the office space by virtue of the creation of 
Cost Pools. Direct Expenses which apply equally to the Retail Space and the office space (such as Landlord’s insurance costs), as reasonably determined by 
Landlord, shall be allocated to the office 

-14-

 
space Cost Pool and the Retail Space Cost Pool based on the square footage of each of those spaces, respectively, compared to the total square footage of 
the applicable Building. After the date of this Lease, Landlord may reasonably establish additional Cost Pools in connection with any new leases of the 
Project, such as a life sciences Cost Pool. Any costs allocated to a Cost Pool (e.g. the Retail Space Cost Pool) which does not include a portion of the 
Premises shall be excluded from the definition of Direct Expenses for the purposes of this Lease.

4.3.3  Costs  Attributable  to  Laboratory  Use.  In  addition  to  the  payment  of  Tenant’s  Share  of  Operating  Expenses  provided  for 
hereinabove,  Tenant  shall  be  solely  responsible  for  the  payment  of  one  hundred  percent  (100%)  of  any  costs  (whether  or  not  otherwise  included  in 
Operating Expenses, but Tenant shall not be directly invoiced for costs already included in Operating Expenses) attributable to, or incurred or payable by 
Landlord as a consequence of, Tenant’s use of any portion of the Premises for the Laboratory Use, as determined by Landlord in its reasonable judgement 
and following the delivery of reasonable documentation supporting said additional costs as attributable to Tenant’s use of a portion of the Premises for the 
Laboratory  Use.  If  not  otherwise  included  as  a  special  allocation  to  Tenant  as  contemplated  by  Section 4.3.2  above  of  any  such  costs  in  the  Operating 
Expense payments made by Tenant, Landlord will invoice Tenant, on a periodic basis, for any such costs, and Tenant shall pay such costs as additional Rent 
hereunder within fifteen (15) days following Landlord’s delivery of any such invoice to Tenant. 

4.4  Calculation  and  Payment  of  Additional  Rent.  Tenant  shall  pay  to  Landlord,  in  the  manner  set  forth  in  Section  4.4.1  below,  and  as 

Additional Rent, Tenant’s Share of Direct Expenses for each Expense Year.

4.4.1 Statement of Actual Direct Expenses and Payment by Tenant. Landlord shall use commercially reasonable efforts to give to 
Tenant  on  or  before  May  1  following  the  end  of  each  Expense  Year,  a  statement  (the  “Statement”)  which  shall  state  the  Direct  Expenses  incurred  or 
accrued for such preceding Expense Year, and which shall indicate the amount of Tenant’s Share of Direct Expenses. Upon receipt of the Statement for 
each Expense Year commencing or ending during the Lease Term, Tenant shall pay, with its next installment of Base Rent due, the full amount of Tenant’s 
Share of Direct Expenses for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Direct Expenses” (as that term is 
defined in Section 4.4.2  below),  and  if  Tenant  paid  more  as  Estimated  Direct  Expenses  than  the  actual  Tenant’s  Share  of  Direct  Expenses,  Tenant  shall 
receive  a  credit  in  the  amount  of  Tenant’s  overpayment  against  Rent  next  due  under  this  Lease  or,  if  Landlord  elects,  Landlord  shall  reimburse  such 
overpayment amount to Tenant or, if the Lease Term has ended, Landlord shall refund such amount to Tenant within thirty (30) days of the date of such 
Statement. The failure of Landlord to timely furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights 
under this Article 4, provided, however, that Tenant shall not be responsible for payment of any Direct Expenses first shown on a Statement delivered more 
than  twenty-four  (24)  months  after  expiration  of  the  applicable  Expense  Year.  Even  though  the  Lease  Term  has  expired  and  Tenant  has  vacated  the 
Premises, when the final determination is made of Tenant’s Share of Direct Expenses for the Expense Year in which this Lease terminates, Tenant shall pay 
to Landlord such amount within thirty (30) days after delivery of the applicable Statement to Tenant, and if Tenant paid more as Estimated Direct Expenses 
than the actual Tenant’s Share of Direct Expenses, Landlord shall, within thirty (30) days after delivery of the applicable Statement to Tenant, pay to Tenant 
the amount of the overpayment. The provisions of this Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term.

4.4.2 Statement of Estimated Direct Expenses. In addition, Landlord shall use commercially reasonable efforts to give Tenant on or 
before May 1 following the end of each Expense Year, a yearly expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s 
reasonable estimate (the “Estimate”) of what the total amount of Direct Expenses for the then-current Expense Year shall be and the estimated Tenant’s 
Share of Direct Expenses (the “Estimated Direct Expenses”). The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall 
not  preclude  Landlord  from  enforcing  its  rights  to  collect  any  Estimated  Direct  Expenses  under  this  Article  4,  nor  shall  Landlord  be  prohibited  from 
revising any Estimate Statement or Estimated Direct Expenses theretofore delivered to the extent necessary (but not more than three (3) times per Expense 
Year). Thereafter, Tenant shall pay, with its next installment of Base Rent due, a fraction of the Estimated Direct Expenses for the then-current Expense 
Year (reduced by any amounts paid pursuant to the last sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of months 
which  have  elapsed  in  such  current  Expense  Year,  including  the  month  of  such  payment,  and  twelve  (12)  as  its  denominator.  Until  a  new  Estimate 
Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time [but not more than three (3) times per Expense Year]), Tenant 
shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Direct Expenses set forth in the 
previous Estimate Statement delivered by Landlord to Tenant.

4.4.3  Mission  Bay  Requirements.  As  set  forth  in  Exhibit  4.4.3  attached  hereto,  the  Project  is  subject  to  certain  covenants, 
requirements,  and  disclosures  (collectively,  the  “Mission  Bay  Requirements”),  which  include,  without  limitation,  certain  limitations  on  (i)  Landlord’s 
ability to lease space at the Project to a Tax-Exempt Entity and (ii) Landlord’s ability to obtain reductions in the assessed value of the Project below the 
Minimum Amount. In connection with the foregoing, to the extent that Tenant is exempt from certain Tax Expenses, but Landlord is otherwise obligated to 
continue to pay such Tax Expenses (the “Tenant-Exempt Tax Expenses”), then, notwithstanding Tenant’s tax-exempt status, Tenant shall continue to be 
obligated to pay to Landlord, as part of Direct Expenses, all such Tenant-Exempt Tax Expenses.

4.5 Taxes and Other Charges for Which Tenant Is Directly Responsible.

4.5.1 Tenant shall be liable for and shall pay before delinquency, taxes levied against Tenant’s equipment, furniture, fixtures and any 
other personal property located in or about the Premises. If any such taxes on Tenant’s equipment, furniture, fixtures and any other personal property are 
levied against Landlord or Landlord’s property or if the assessed value of Landlord’s property is increased by the inclusion therein of a value placed upon 
such equipment, furniture, fixtures or any other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord 
shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall within thirty (30) days after 
Landlord’s demand (together with reasonable back-up evidencing the same) repay to Landlord the taxes so levied against Landlord or the proportion of 
such taxes resulting from such increase in the assessment, as the case may be.

4.5.2 If the improvements in the Premises, whether installed and/or paid for by Landlord or Tenant and whether or not affixed to the 
real property so as to become a part thereof, are assessed for real property tax purposes at a valuation higher than the valuation at which “building standard” 
improvements are assessed, then the Tax Expenses levied against Landlord or the property by reason of such excess assessed valuation shall be deemed to 
be taxes levied against personal property of Tenant and shall be governed by the provisions of Section 4.5.1 above. Landlord and Tenant hereby agree that 
the valuation of Landlord’s “building standard” improvements for all tenants of the Project shall be equal to One Hundred Dollars ($100.00) per rentable 
square foot. Landlord and Tenant shall cooperate with respect to the information provided by either of them to the appropriate taxing authority regarding 
the valuation of the improvements in the Premises so as to avoid duplicative assessments being levied on such improvements.

4.5.3 Notwithstanding any contrary provision herein, Tenant shall pay prior to delinquency any (i) rent tax (e.g., gross receipts tax on 
commercial rents) or sales tax, service tax, transfer tax or value added tax, or any other applicable tax on the rent or services herein or otherwise respecting 
this Lease, or (ii) taxes assessed upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy 
by Tenant of the Premises or any portion of the Project, including the Parking Facilities.

4.6 Landlord’s Books and Records.  Following  Tenant’s  receipt  of  a  Statement,  Tenant  shall  have  the  right  by  written  notice  to  Landlord  to 
commence  and  complete  an  audit  of  Landlord’s  books  concerning  the  Direct  Expenses  for  the  Expense  Year  which  are  the  subject  of  such  Statement, 
within  the  later  to  occur  of  (x)  six  (6)  months  following  the  delivery  of  such  Statement  and  (y)  the  date  that  is  sixty  (60)  days  after  Landlord  makes 
Landlord’s books and records available for Tenant’s audit, provided that Tenant notifies Landlord of Tenant’s intent to audit Landlord’s books and records 
within the six (6) month period described in clause (x) above (the “Audit Period”). Following the giving of such written notice, Tenant shall have the right 
during Landlord’s regular business hours taking into account the workload of Landlord’s employees involved in the audit at the time of the audit request 
and on reasonable prior notice, to audit, at Landlord’s corporate offices in the San Francisco Bay area, at Tenant’s sole cost, Landlord’s records, provided 
that Tenant is not then in Default. The audit of Landlord’s records may be conducted only by a reputable certified public accountant, subject to Landlord’s 
approval, which approval shall not be unreasonably withheld. Any accounting firm selected by Tenant in connection with the audit (i) shall be a reputable 
independent nationally or regionally recognized certified public accounting firm which has previous experience in auditing financial operating records of 
landlords of office/life science buildings; (ii) shall not already be providing accounting and/or lease administration services to Tenant and shall not have 
provided accounting and/or lease administration services to Tenant in the past three (3) years; (iii) shall not be retained by Tenant on a contingency fee 
basis (i.e. Tenant must be billed based on the actual time and materials that are incurred by the accounting firm in the performance of the audit), a copy of 
the executed audit agreement, between Tenant and auditor, shall be provided to Landlord prior to the commencement of the audit; and (iv) at Landlord’s 
option, both Tenant and its agent shall be 

-16-

 
required  to  execute  a  commercially  reasonable  confidentially  agreement  prepared  by  Landlord.  Any  audit  report  prepared  by  Tenant’s  auditors  shall  be 
delivered concurrently to Landlord and Tenant within the Audit Period. If, after such audit of Landlord’s records, Tenant disputes the amount of Direct 
Expenses for the year under audit, Landlord and Tenant shall meet and attempt in good faith to resolve the dispute. If the parties are unable to resolve the 
dispute within sixty (60) days after completion of Tenant’s audit, then, at Tenant’s request, a certified public accounting firm selected by Landlord, and 
reasonably approved by Tenant, shall, at Tenant’s cost, conduct an audit of the relevant Direct Expenses (the “Neutral Audit”). Tenant shall pay all costs 
and expenses of the Neutral Audit unless the final determination in such Neutral Audit is that Landlord overstated Direct Expenses in the Statement for the 
year  being  audited  by  more  than  five  percent  (5%)  in  which  case  Landlord  shall  pay  all  costs  and  expenses  of  the  Neutral  Audit,  as  well  as  Tenant’s 
reasonable out-of-pocket costs actually incurred by Tenant in the audit of Landlord’s books and records. In any event, Landlord will reimburse or provide a 
credit  for  any  overstatement  of  Direct  Expenses  and  Tenant  shall  pay  to  Landlord  any  understatement  of  Direct  Expenses.  To  the  extent  Landlord  and 
Tenant fail to otherwise reach mutual agreement regarding Direct Expenses, the foregoing audit and Neutral Audit procedures shall be the sole methods to 
be used by Tenant to dispute the amount of any Direct Expenses payable by Tenant pursuant to the terms of the Lease.

5. USE OF PREMISES

5.1 Permitted Use. Tenant shall use the Premises solely for the Permitted Use set forth in Section 8 of the Summary and Tenant shall not use or 
permit the Premises or the Project to be used for any other purpose or purposes whatsoever without the prior written consent of Landlord, which consent 
may be withheld in Landlord’s sole discretion.

5.2 Prohibited Uses. The uses prohibited under this Lease shall include, without limitation, use of the Premises or a portion thereof for (i) offices 
of any agency or bureau of the United States or any state or political subdivision thereof; (ii) offices or agencies of any foreign governmental or political 
subdivision thereof; (iii) offices of any health care professionals or service organization (but occupational health professionals employed by Tenant shall 
not violate the foregoing prohibition); (iv) schools or other training facilities which are not ancillary to corporate, executive or professional office use; (v) 
retail use or the operation of any restaurant offering services to the public; or (vi) communications firms such as radio and/or television stations. Tenant 
further covenants and agrees that Tenant shall not use, or suffer or permit any person or persons claiming by, through, or under Tenant to use, the Premises 
or  any  part  thereof  for  any  use  or  purpose  contrary  to  the  provisions  of  the  Rules  and  Regulations  attached  hereto  as  Exhibit 5.2,  as  the  same  may  be 
amended  by  Landlord  from  time  to  time  (the  “Rules  and  Regulations”),  or  in  violation  of  Applicable  Laws  or  any  Underlying  Documents.  Any 
modifications  to  the  Rules  and  Regulations  shall  be  reasonable  and  non-discriminatory  and  shall  be  provided  to  Tenant  in  writing  or  posted  to  a 
conspicuous place in the Building. In the event of a conflict between any modifications to the Rules and Regulations and the terms of this Lease, the latter 
shall control. Tenant shall not do or permit anything to be done in or about the Premises which will in any way damage the reputation of the Project or 
unreasonably obstruct or interfere with the rights of other tenants or occupants of the Building, or injure or annoy them or use or allow the Premises to be 
used for any improper, unlawful or objectionable purpose, nor shall Tenant cause, maintain or permit any nuisance in, on or about the Premises. Tenant 
shall comply with, and Tenant’s rights and obligations under the Lease and Tenant’s use of the Premises shall be subject and subordinate to, all Underlying 
Documents; provided that, following the date of this Lease, Landlord shall not voluntarily enter into new, or modify existing, Underlying Documents that 
would unreasonably interfere with Tenant’s access to the Premises or use of the Premises for the Permitted Use. Tenant shall only place equipment within 
the  Premises  with  floor  loading  consistent  with  the  Building’s  structural  design,  and  such  equipment  shall  be  placed  in  a  location  designed  to  carry  the 
weight of such equipment. Tenant shall cause any equipment or machinery to be installed in the Premises so as to reasonably prevent sounds or vibrations 
therefrom from extending into the Common Areas or other offices in the Project.

5.3 Tenant’s Bicycles.  Tenant’s  employees  shall  be  permitted  to  bring  their  bicycles  (“Bicycles”)  into  portions  of  the  Project  designated  by 
Landlord for Bicycle storage, subject to the provisions of this Section 5.3, and such additional reasonable rules and regulations as may be promulgated by 
Landlord  from  time  to  time  (in  Landlord’s  reasonable  discretion)  that  do  not  unreasonably  interfere  with  Tenant’s  ability  to  park  its  Bicycles  as 
contemplated  herein  and  provided  to  Tenant,  and  only  to  the  extent  such  Bicycles  are  used  on  a  daily  basis  for  commuting  to  and  from  work  by  such 
employees.  AT  NO  TIME  ARE  RIDERS  ALLOWED  TO  RIDE  ANY  BICYCLE  IN  THE  PREMISES,  THE  PARKING  FACILITIES  OR  THE 
BUILDINGS. Storage of any Bicycle anywhere on the Project 

-17-

 
other  than  as  expressly  set  forth  in  this  Section  5.3  is  prohibited.  Tenant  shall  keep  its  employees  informed  of  these  rules  and  regulations  and  any 
modifications thereto.

5.3.1 Bicycle Storage Area. The Parking Facilities include a secured bicycle storage area that will accommodate at least two hundred 
(200) Bicycles (collectively, the “Landlord Bicycle Storage Area”). Tenant shall have the non-exclusive right (at no additional charge other than Tenant’s 
Share of Direct Expenses relating thereto) to use the Landlord Bicycle Storage Area for day use parking of Bicycles by Tenant and Tenant’s employees, 
visitors,  invitees  and  sublessees  not  to  exceed  Tenant’s  pro  rata  share  (which  is  presently  40  based  on  the  Landlord  Bicycle  Storage  presently 
accommodating up to 228 Bicycles) of the number of Bicycles that the Landlord Bicycle Storage Area from time to time accommodates (which shall not be 
less than 200 Bicycles), and Tenant shall also have the right, at Tenant’s sole cost and expense, to convert certain areas of the Parking Facilities, reasonably 
designated by Landlord and approved by Tenant, for additional exclusive day use parking (the “Tenant Bicycle Storage Area”) for Bicycles by Tenant and 
its employees, visitors, invitees and sublessees, which shall include the installation of Bicycle storage lockers or other Bicycle storage facilities, installed as 
an  Alteration  (“Bicycle Improvements”).  The  Landlord  Bicycle  Storage  Area  and  Tenant  Bicycle  Storage  Area  are  collectively,  the  “Bicycle  Storage 
Area”.  Other  than  the  Bicycle  Storage  Area,  Tenant  and  Tenant’s  employees,  visitors,  invitees  and  sublessees  shall  not  be  entitled  to  use  any  secured 
bicycle storage areas at the Project, and Tenant’s employees shall not be permitted to bring their Bicycles in the Premises. Motorized vehicles of any kind, 
including motorcycles and mopeds, are prohibited in the Bicycle Storage Area, as is the storage of any property other than Bicycles. Each rider shall use the 
Bicycle Storage Area at its sole risk. Landlord specifically reserves the right to reasonably change the location, size, configuration, design, layout and all 
other aspects of the Landlord Bicycle Storage Area at any time (provided that no such action will materially diminish the capacity of the Landlord Bicycle 
Storage  Area  on  other  than  a  temporary  basis),  and  Tenant  acknowledges  and  agrees  that  Landlord  may,  without  incurring  any  liability  to  Tenant  and 
without any abatement of Rent under this Lease, from time to time, temporarily close-off or restrict access to the Bicycle Storage Area for purposes of 
permitting or facilitating any such construction, alteration or improvements. Landlord has no obligation to provide any security whatsoever in connection 
with the Bicycle Storage Area except as expressly set forth in this Section 5.3.1. Landlord shall provide twenty-four (24) hours per day, seven (7) days per 
week, reasonable access control services for the Landlord Bicycle Storage Area in a manner materially consistent with the services provided by landlords 
of Comparable Buildings. Notwithstanding the foregoing, Landlord shall in no case be liable for personal injury or property damage for any error with 
regard to the admission to or exclusion from the Bicycle Storage Area of any person. Upon the expiration or earlier termination of this Lease, Tenant shall 
have removed all Bicycles belonging to its employees from the Bicycle Storage Area and Tenant, at Tenant’s sole cost and expense, shall repair all damage 
to the Bicycle Storage Area caused by the removal of Tenant’s property therefrom, and if Tenant fails to repair such damage, Landlord may undertake such 
repair on account of Tenant and Tenant shall pay to Landlord upon demand the cost of such repair. If Tenant fails to remove any Bicycles at the expiration 
or earlier termination of this Lease, Landlord may dispose of said Bicycles in such lawful manner as it shall determine in its sole and absolute discretion.

5.4  Tenant’s  Use  of  Base  Building  Stairwells.  Subject  to  Applicable  Laws  and  Tenant’s  receipt  of  all  necessary  governmental  or  quasi-
governmental  approvals  (collectively,  “Governmental Approvals”),  Tenant  shall  have  right  during  the  Lease  Term  to  use  the  base  building  stairwells 
between the floors of the Premises (each, a “Stairwell”) solely for purposes of ingress and egress from and between different floors of the Premises. In its 
use of the Stairwells, Tenant shall comply with all Applicable Laws, Governmental Approvals and the rules and regulations for the Project. Tenant shall 
have no right to alter or change any Stairwell in any manner whatsoever, except that Tenant may paint or perform other purely decorative Alterations or 
Improvements to the Stairwells in accordance with Article 8 or the Work Letter, as applicable, and may install Tenant’s Security System as set forth in 
Section 6.1.11 below. Tenant acknowledges and agrees that Tenant’s use of the Stairwells shall be at Tenant’s sole risk and Landlord shall have no liability 
whatsoever in connection therewith. Tenant hereby waives any and all claims against Landlord for any damages arising from Tenant’s exercise of its rights 
under this Section 5.5.

5.5 Hazardous Materials.

5.5.1 Tenant’s Obligations.

accurately completed Landlord’s Pre-Leasing Environmental Exposure Questionnaire 

5.5.1.1  Prohibitions.  As  a  material  inducement  to  Landlord  to  enter  into  this  Lease  with  Tenant,  Tenant  has  fully  and 

-18-

 
 
(the  “Environmental  Questionnaire”),  which  is  attached  as  Exhibit  5.5.1.1.  Tenant  hereby  represents,  warrants  and  covenants  that  except  for  those 
chemicals  or  materials,  and  their  respective  quantities,  specifically  listed  on  the  Environmental  Questionnaire  (as  may  be  updated  from  time  to  time  as 
described  below),  neither  Tenant  nor  Tenant’s  subtenants  or  assigns,  or  any  of  their  respective  employees,  contractors  and  subcontractors  of  any  tier, 
entities with a contractual relationship with such parties (other than Landlord), or any entity acting as an agent or sub-agent of such parties or any of the 
foregoing (collectively, “Tenant Parties”) will produce, use, store or generate any “Hazardous Materials”, as that term is defined below, on, under or about 
the Premises, nor cause or permit any Hazardous Material to be brought upon, placed, stored, manufactured, generated, blended, handled, recycled, used or 
“Released”,  as  that  term  is  defined  below,  on,  in,  under  or  about  the  Premises  or  Project.  If  any  information  provided  to  Landlord  by  Tenant  on  the 
Environmental Questionnaire, or otherwise relating to information concerning Hazardous Materials is intentionally false, incomplete, or misleading in any 
material respect, the same shall be deemed a default by Tenant under this Lease. Upon Landlord’s request, or in the event of any “Material Change” in 
Tenant’s use of Hazardous Materials at the Premises, Tenant shall deliver to Landlord an updated Environmental Questionnaire. As used herein, “Material 
Change” shall refer to any change in the use, presence (including, without limitation, a material change in the quantity stored within the Premises at any 
one time) or handling of Hazardous Materials by Tenant that would (A)reasonably be expected to have a significant effect on the Premises or the Project, 
(B)  violate  the  compliance  with  or  provisions  of  any  existing  permits,  licenses,  registrations  and  other  similar  documents  used  by  any  governmental  or 
quasi-governmental authority that authorizes any use, storage or handling of Hazardous Materials in, on or about the Premises or the Project by Tenant or 
any Tenant Parties, or (C) cause the information provided in the Environmental Questionnaire, as previously updated from time to time, to become untrue 
or inaccurate in any material respect. Landlord’s prior written consent shall be required for any Hazardous Materials use for the Premises not described on 
the initial Environmental Questionnaire, but such consent not to be unreasonably withheld, conditioned or delayed. Whenever Tenant submits to Landlord 
an updated Environmental Questionnaire, Landlord shall respond to Tenant within five (5) business days with its approval or disapproval thereof. Tenant 
shall not install or permit any underground storage tank on the Premises. In addition, Tenant agrees that it: (i) shall not cause or suffer to occur, the Release 
(as defined below) of any Hazardous Materials at, upon, under or within the Premises or any contiguous or adjacent premises; and (ii) shall not engage in 
activities at the Premises that give rise to, or lead to the imposition of, liability upon Tenant or Landlord or the creation of an environmental lien or use 
restriction upon the Premises. For purposes of this Lease, “Hazardous Materials” means all flammable explosives, petroleum and petroleum products, oil, 
radon,  radioactive  materials,  toxic  pollutants,  asbestos,  polychlorinated  biphenyls  (“PCBs”),  medical  waste,  chemicals  known  to  cause  cancer  or 
reproductive toxicity, pollutants, contaminants, hazardous wastes, toxic substances or related materials, including without limitation any chemical, element, 
compound,  mixture,  solution,  substance,  object,  waste  or  any  combination  thereof,  which  is  or  may  hereafter  be  determined  to  be  hazardous  to  human 
health, safety or to the environment due to its radioactivity, ignitability, corrosiveness, reactivity, explosiveness, toxicity, carcinogenicity, infectiousness or 
other harmful or potentially harmful properties or effects, or defined as, regulated as or included in, the definition of “hazardous substances”, “hazardous 
wastes”, “hazardous materials”, or “toxic substances” under any Environmental Laws. The term “Hazardous Materials” for purposes of this Lease shall 
also  include  any  mold,  fungus  or  spores,  whether  or  not  the  same  is  defined,  listed,  or  otherwise  classified  as  a  “hazardous  material”  under  any 
Environmental Laws, if such mold, fungus or spores may pose a risk to human health or the environment or negatively impact the value of the Premises. 
Hazardous Materials shall also include any “biohazardous waste,” “medical waste,” or other waste under California Health and Safety Code Division 20, 
Chapter  6.1  (Medical  Waste  Management  Act).    For  purposes  of  this  Lease,  “Release”  or  “Released”  or  “Releases”  shall  mean  any  release,  deposit, 
discharge,  emission,  leaking,  spilling,  seeping,  migrating,  injecting,  pumping,  pouring,  emptying,  escaping,  dumping,  disposing,  or  other  movement  of 
Hazardous Materials into the environment.

Any use or storage of Hazardous Materials by Tenant permitted pursuant to this Article 5 shall not exceed Tenant’s legally permissible quantity 
of  similarly  classed  Hazardous  Materials.  Notwithstanding  anything  contained  herein  to  the  contrary,  in  no  event  shall  Tenant  or  anyone  claiming  by 
through  or  under  Tenant  perform  work  above  the  risk  category  Biosafety  Level  3  as  established  by  the  Department  of  Health  and  Human  Services 
(“DHHS”) and as further described in the DHHS publication Biosafety in Microbiological and Biomedical Laboratories (5th Edition) (as it may be or may 
have been further revised, the “BMBL”) or such nationally recognized new or replacement standards as Landlord may reasonable designate. Tenant shall 
comply with all applicable provisions of the standards of the BMBL to the extent applicable to Tenant’s operations in the Premises.

5.5.1.2 Notices to Landlord. Unless Tenant is required by Applicable Laws to give earlier notice to Landlord, Tenant shall 
notify  Landlord  in  writing  as  soon  as  possible  but  in  no  event  later  than  five  (5)  days  after  (i)  Tenant  becomes  aware  of  the  occurrence  of  any  actual, 
alleged or threatened Release of any Hazardous Material in, on, under, from, about or in the vicinity of the Premises (whether past or present), regardless of 
the source or quantity of any such Release, or (ii) Tenant becomes aware of any regulatory actions, inquiries, inspections, investigations, directives, or any 
cleanup,  compliance,  enforcement  or  abatement  proceedings  (including  any  threatened  or  contemplated  investigations  or  proceedings)  relating  to  or 
potentially affecting the Premises, or (iii) Tenant becomes aware of any claims by any person or entity relating to any Hazardous Materials in, on, under, 
from,  about  or  in  the  vicinity  of  the  Premises,  whether  relating  to  damage,  contribution,  cost  recovery,  compensation,  loss  or  injury.  Collectively,  the 
matters set forth in clauses (i), (ii) and (iii) above are hereinafter referred to as “Hazardous Materials Claims”. Tenant shall promptly forward to Landlord 
copies of all orders, notices, permits, applications and other communications and reports in connection with any Hazardous Materials Claims. Additionally, 
Tenant  shall  promptly  advise  Landlord  in  writing  of  Tenant’s  discovery  of  any  occurrence  or  condition  on,  in,  under  or  about  the  Premises  that  could 
subject Tenant or Landlord to any liability, or restrictions on ownership, occupancy, transferability or use of the Premises under any “Environmental Laws”, 
as that term is defined below. Tenant shall not enter into any legal proceeding or other action, settlement, consent decree or other compromise with respect 
to  any  Hazardous  Materials  Claims  without  first  notifying  Landlord  of  Tenant’s  intention  to  do  so  and  affording  Landlord  the  opportunity  to  join  and 
participate, as a party if Landlord so elects, in such proceedings and in no event shall Tenant enter into any agreements which are binding on Landlord or 
the Project without Landlord’s prior written consent. Landlord shall have the right to appear at and participate in, any and all legal or other administrative 
proceedings concerning any Hazardous Materials Claim.  For purposes of this Lease, “Environmental Laws” means all applicable present and future laws 
relating to the protection of human health, safety, wildlife or the environment, including, without limitation, (i) all requirements pertaining to reporting, 
licensing, permitting, investigation and/or remediation of emissions, discharges, Releases, or threatened Releases of Hazardous Materials, whether solid, 
liquid, or gaseous in nature, into the air, surface water, groundwater, or land, or relating to the manufacture, processing, distribution, use, treatment, storage, 
disposal,  transport,  or  handling  of  Hazardous  Materials;  and  (ii)  all  requirements  pertaining  to  the  health  and  safety  of  employees  or  the  public.

5.5.1.3 Releases of Hazardous Materials. If due to the acts or omissions of Tenant or any Tenant Party any Release of any 
Hazardous  Material  in,  on,  under,  from  or  about  the  Premises  in  violation  of,  or  requiring  any  Clean-Up  (as  defined  below),  in  addition  to  notifying 
Landlord  as  specified  above,  Tenant,  at  its  own  sole  cost  and  expense,  shall  (i)  immediately  comply  with  any  and  all  reporting  requirements  imposed 
pursuant  to  any  and  all  Environmental  Laws,  (ii)  provide  a  written  certification  to  Landlord  indicating  that  Tenant  has  complied  with  all  applicable 
reporting  requirements,  (iii)  take  any  and  all  necessary  investigation,  corrective,  remedial  and  other  Clean-up  action  in  accordance  with  any  and  all 
applicable  Environmental  Laws,  utilizing  an  environmental  consultant  reasonably  approved  by  Landlord,  all  in  accordance  with  the  provisions  and 
requirements  of  this  Section  5.6,  including,  without  limitation,  Section  5.5.4,  and  (iv)  take  any  such  additional  investigative,  remedial  and  corrective 
actions as Landlord shall in its reasonable discretion deem necessary such that the Premises and Project are remediated to a condition allowing unrestricted 
use  of  the  Premises  (i.e.,  to  a  level  that  will  allow  any  future  use  of  the  Premises,  including  residential,  without  any  engineering  controls  or  deed 
restrictions), all in accordance with the provisions and requirements of this Section 5.5. Landlord may, as required by any and all Environmental Laws, 
report  the  Release  of  any  Hazardous  Material  by  Tenant  or  any  Tenant  Party  to  the  appropriate  governmental  authority,  identifying  Tenant  as  the 
responsible party. Tenant shall deliver to Landlord copies of all administrative orders, notices, demands, directives or other communications directed to 
Tenant from any governmental authority with respect to any Release 

-20-

 
of Hazardous Materials in, on, under, from, or about the Premises, together with copies of all investigation, assessment, and remediation plans and reports 
prepared by or on behalf of Tenant in response to any such regulatory order or directive.

5.5.1.4 Indemnification.

5.5.1.4.1 In General. Without limiting in any way Tenant’s obligations under any other provision of this Lease, 
Tenant shall be solely responsible for and shall protect, defend, indemnify and hold the Landlord Parties harmless from and against any and all claims, 
judgments, losses, damages, costs, expenses, penalties, enforcement actions, taxes, fines, remedial actions, liabilities (including, without limitation, actual 
attorneys’ fees, litigation, arbitration and administrative proceeding costs, expert and consultant fees and laboratory costs) including, without limitation, 
consequential damages and sums paid in settlement of claims, which arise during or after the Lease Term, whether foreseeable or unforeseeable, directly or 
indirectly arising out of or attributable to the presence, use, generation, manufacture, treatment, handling, refining, production, processing, storage, Release 
or presence of Hazardous Materials in, on, under or about the Premises or Project by any Tenant Party, except to the extent such liabilities result from the 
negligence  or  willful  misconduct  of  Landlord  following  the  Lease  Commencement  Date.  The  foregoing  obligations  of  Tenant  shall  include,  without 
limitation:  (i)  the  costs  of  any  required  or  necessary  removal,  repair,  cleanup  or  remediation  of  the  Premises  and  Project,  and  the  preparation  and 
implementation of any closure, removal, remedial or other required plans; (ii) judgments for personal injury or property damages; and (iii) all costs and 
expenses incurred by Landlord in connection therewith. It is the express intention of the parties to this Lease that Tenant assumes all such liabilities, and 
holds Landlord harmless from all such liabilities, associated with the environmental condition of the Premises, arising on or after the date Tenant takes 
possession of the Premises.

5.5.1.4.2 Limitations. Notwithstanding anything to the contrary in this Lease, Tenant shall not be responsible to 
remediate  nor  otherwise  be  liable  or  responsible  for  (not  shall  Tenant  be  responsible  to  indemnify  Landlord  with  respect  to  except  to  the  extent  that 
Tenant’s construction activities and/or Tenant’s other acts or omissions caused or exacerbated the subject claim) any Hazardous Materials (i) located in, on, 
under or about the Project, Building and/or Premises prior to the date of the Existing Sublease, (ii) brought upon the Project by Landlord or any Landlord 
Party(ies), or (iii) that have migrated onto the Project, Building and/or Premises from other properties or premises (“Landlord’s Hazardous Materials”), 
except to the extent any of the Hazardous Materials described in items (i), (ii) or (iii) are generated, used, transported, exacerbated, released or disturbed, by 
Tenant or any Tenant Party. To the extent that Landlord’s Hazardous Materials are discovered at the Project, Building or Premises and remediation of the 
same is required a governmental authority with jurisdiction (which remediation is not triggered because of the particular use of the Premises by Tenant or 
its  subtenants  or  assigns),  any  remediation  thereof  of  the  Landlord’s  Hazardous  Substances  (to  the  extent  required  by  the  applicable  governmental 
authority) by Landlord shall be at Landlord’s sole cost and expense, and not subject to inclusion in Operating Expenses.

5.5.1.5  Compliance  with  Environmental  Laws.  Without  limiting  the  generality  of  Tenant’s  obligation  to  comply  with 
Applicable Laws as otherwise provided in this Lease, Tenant shall, at its sole cost and expense, comply with all Environmental Laws applicable to the use, 
handling, storage and disposal by Tenant or by any Tenant’s Agents of any Hazardous Materials. Tenant shall obtain and maintain any and all necessary 
permits, licenses, certifications and approvals appropriate or required for the use, handling, storage, and disposal of any Hazardous Materials used, stored, 
generated,  transported,  handled,  blended,  or  recycled  by  Tenant  on  the  Premises.  Landlord  shall  have  a  continuing  right,  without  obligation,  to  require 
Tenant to obtain, and to review and inspect any and all such permits, licenses, certifications and approvals, together with copies of any and all Hazardous 
Materials  management  plans  and  programs,  any  and  all  Hazardous  Materials  risk  management  and  pollution  prevention  programs,  and  any  and  all 
Hazardous Materials emergency response and employee training programs respecting Tenant’s use of Hazardous Materials. If Landlord has grounds to be 
concerned that Tenant has failed to comply with the provisions of this Article 5, then upon request of Landlord, Tenant shall deliver to Landlord a narrative 
description  explaining  the  nature  and  scope  of  Tenant’s  activities  involving  Hazardous  Materials  and  showing  to  Landlord’s  reasonable  satisfaction 
compliance with all Environmental Laws and the terms of this Lease.

5.5.2 Assurance of Performance.

5.5.2.1  Environmental  Assessments  In  General.  Provided  that  Landlord  gives  Tenant  no  less  than  two  (2)  days  prior 
notice of intended entry (other than in any emergency context) and complies with Tenant’s security measures then in effect Landlord may, but shall not be 
required to, engage from time to time such contractors 

-21-

 
as Landlord determines to be appropriate to perform “Environmental Assessments”, as that term is defined below, to ensure Tenant’s compliance with the 
requirements of this Lease with respect to Hazardous Materials. For purposes of this Lease, “Environmental Assessment” means an assessment including, 
without limitation: (i) an environmental site assessment conducted in accordance with the then-current standards of the American Society for Testing and 
Materials and meeting the requirements for satisfying the “all appropriate inquiries” requirements; and (ii) sampling and testing of the Premises based upon 
potential recognized environmental conditions or areas of concern or inquiry identified by the environmental site assessment.

5.5.2.2 Costs of Environmental Assessments. All costs and expenses incurred by Landlord in connection with any such 
Environmental Assessment initially shall be paid by Landlord; provided that if any such Environmental Assessment shows that Tenant has failed to comply 
with the provisions of this Section 5.5, then all of the costs and expenses of such Environmental Assessment shall be reimbursed by Tenant as Additional 
Rent within thirty (30) days after receipt of written demand therefor, together with documentation of such cost.

5.5.3 Tenant’s Obligations upon Surrender. At the expiration or earlier termination of the Lease Term, Tenant, at Tenant’s sole cost 
and  expense,  shall:  (i)  cause  an  Environmental  Assessment  of  the  Premises  to  be  conducted  in  accordance  with  Section 15.3;  (ii)  cause  all  Hazardous 
Materials  for  which  Tenant  is  responsible  for  under  this  Lease  to  be  removed  from  the  Premises  and  disposed  of  in  accordance  with  all  Environmental 
Laws and as necessary to allow the Premises to be used for any purpose in a manner consistent with Comparable Buildings (but for the sake of clarity, 
Tenant’s  return  to  Landlord  of  the  Premises  in  the  condition  that  existed  prior  to  the  Lease  Commencement  Date  shall  satisfy  Tenant’s  obligation  as  to 
removal  of  Hazardous  Materials  from  the  Premises);  and  (iii)  cause  to  be  removed  all  containers  installed  or  used  by  any  Tenant  Parties  to  store  any 
Hazardous Materials on the Premises, and cause to be repaired any damage to the Premises caused by such removal.

5.5.4 Clean-up.

5.5.4.1  Environmental  Reports;  Clean-Up.  If  any  written  report,  including  any  report  containing  results  of  any 
Environmental Assessment (an “Environmental Report”) shall indicate (i) the presence of any Hazardous Materials as to which Tenant has a removal or 
remediation obligation under this Section 5.5, and (ii) that as a result of same, the investigation, characterization, monitoring, assessment, repair, closure, 
remediation, removal, or other clean-up (the “Clean-up”) of any Hazardous Materials is required, Tenant shall immediately prepare and submit to Landlord 
within  thirty  (30)  days  after  receipt  of  the  Environmental  Report  a  comprehensive  plan,  subject  to  Landlord’s  written  approval  (not  to  be  unreasonably 
withheld), specifying the actions to be taken by Tenant to perform the Clean-up so that the Premises are restored to the conditions required by this Lease. 
Upon Landlord’s approval of the Clean-up plan, Tenant shall, at Tenant’s sole cost and expense, without limitation of any rights and remedies of Landlord 
under this Lease, immediately implement such plan with a consultant reasonably acceptable to Landlord and proceed to Clean-Up Hazardous Materials in 
accordance with all applicable laws and as required by such plan and this Lease. If, within thirty (30) days after receiving a copy of such Environmental 
Report, Tenant fails either (a) to complete such Clean-up, or (b) with respect to any Clean-up that cannot be completed within such 30-day period, fails to 
proceed with diligence to prepare the Clean-up plan and complete the Clean-up as promptly as practicable, then Landlord shall have the right, but not the 
obligation, and without waiving any other rights under this Lease, to carry out any Clean-up recommended by the Environmental Report or required by any 
governmental authority having jurisdiction over the Premises, and recover all of the costs and expenses thereof from Tenant as Additional Rent, payable 
within thirty (30) days after receipt of written demand therefor, together with documentation of such cost.

5.5.4.2 No Rent Abatement. Tenant shall continue to pay all Rent due or accruing under this Lease during any Clean-up, 
and shall not be entitled to any reduction, offset or deferral of any Base Rent or Additional Rent due or accruing under this Lease during any such Clean-
up.

5.5.4.3 Surrender of Premises. Tenant shall complete any Clean-up required by this Section 5.5 prior to surrender of the 
Premises  upon  the  expiration  or  earlier  termination  of  this  Lease  and  shall  fully  comply  with  all  Environmental  Laws  and  requirements  of  any 
governmental  authority  with  respect  to  such  completion,  including,  without  limitation,  fully  comply  with  any  requirement  to  file  a  risk  assessment, 
mitigation plan or other information with any such governmental authority in conjunction with the Clean-up prior to such surrender. If applicable, Tenant 
shall obtain and deliver to Landlord a letter or other written determination from the overseeing governmental authority confirming that the Clean-up has 
been completed in accordance with all requirements of such 

-22-

 
governmental authority and that no further response action of any kind is required for the unrestricted use of the Premises (“Closure Letter”), unless such 
governmental authority’s standard practices at the relevant time do not provide for such Closure Letter. Upon the expiration or earlier termination of this 
Lease, Tenant shall also be obligated to close all permits obtained in connection with Hazardous Materials in accordance with Applicable Laws.

5.5.4.4 Failure to Timely Clean-Up. Should any Clean-up for which Tenant is responsible for under this Section 5.5 not be 
completed, or should Tenant not receive the Closure Letter (unless such governmental authority’s standard practices at the relevant time do not provide for 
such  Closure  Letter)  and  any  governmental  approvals  required  under  Environmental  Laws  in  conjunction  with  such  Clean-up  prior  to  the  expiration  or 
earlier termination of this Lease, and Tenant’s failure to receive the Closure Letter is prohibiting Landlord from leasing the Premises or any part thereof to a 
third party, or prevents the occupancy or use of the Premises or any part thereof by a third party, then Tenant shall be liable to Landlord as a holdover tenant 
(as more particularly provided in Article 16) until Tenant has fully complied with its obligations under this Section 5.5.

5.5.5 Confidentiality. Unless compelled to do so by applicable law, Tenant agrees that Tenant shall not disclose, discuss, disseminate 
or  copy  any  information,  data,  findings,  communications,  conclusions  and  reports  regarding  the  environmental  condition  of  the  Premises  to  any  Person 
(other  than  Tenant’s  consultants,  attorneys,  property  managers  and  employees  that  have  a  need  to  know  such  information),  including  any  governmental 
authority, without the prior written consent of Landlord. In the event Tenant reasonably believes that disclosure is required by Applicable Laws, it shall 
provide Landlord ten (10) days’ advance notice (or such shorter time as may be necessary due to applicable laws) of disclosure of confidential information 
so that Landlord may attempt to obtain a protective order. Tenant may additionally release such information to bona fide prospective purchasers, lenders, 
assignees or subtenants, subject to any such parties’ written agreement to be bound by the terms of this Section 5.5.

5.5.6 Copies of Environmental Reports. Within thirty (30) days of receipt thereof, Tenant shall provide Landlord with a copy of any 
and all environmental assessments, audits, studies and reports regarding Tenant’s activities with respect to the Premises, or ground water beneath the Land, 
or the environmental condition or Clean-up thereof that are in Tenant’s possession or control. Tenant shall be obligated to provide Landlord with a copy of 
such  materials  without  regard  to  whether  such  materials  are  generated  by  Tenant  or  prepared  for  Tenant,  or  how  Tenant  comes  into  possession  of  such 
materials, unless to do so would expose Tenant to a claim of breach of nondisclosure obligation or be a violation of applicable law.

5.5.7  Signs,  Response  Plans,  Etc.  Tenant  shall  be  responsible  for  posting  on  the  Premises  any  signs  required  under  applicable 
Environmental  Laws.  Tenant  shall  also  complete  and  file  any  business  response  plans  or  inventories  required  by  any  applicable  Environmental  Laws. 
Tenant shall concurrently file a copy of any such business response plan or inventory with Landlord.

5.5.8 Survival. Each covenant, agreement, representation, warranty and indemnification made by Tenant set forth in this Section 5.5 
shall survive the expiration or earlier termination of this Lease and shall remain effective until all of Tenant’s obligations under this Section 5.5 have been 
completely performed and satisfied.

5.6 Premises Compliance with ADA. Notwithstanding any other provision herein to the contrary, Tenant shall be responsible for all liabilities, 
costs and expenses arising out of or in connection with the compliance of the Premises with the Americans with Disabilities Act, 42 U.S.C. § 1210 I, et 
seq., and any state and local accessibility laws, codes, ordinances and rules (collectively, and together with regulations promulgated pursuant thereto, the 
“ADA”), and Tenant shall indemnify, save, defend (at Landlord’s option and with counsel reasonably acceptable to Landlord) and hold Landlord and its 
affiliates, employees, agents and contractors; and any lender, mortgagee or beneficiary (each, a “Lender” and, collectively with Landlord its partners and 
subpartners,  and  their  respective  officers,  members,  directors,  shareholders,  agents,  property  managers,  employees  and  independent  contractors,  the 
“Landlord  Indemnitees”)  harmless  from  and  against  any  demands,  claims,  liabilities,  losses,  costs,  expenses,  actions,  causes  of  action,  damages  or 
judgments, and all reasonable expenses (including reasonable attorneys’ fees, charges and disbursements) incurred in investigating or resisting the same 
(collectively, “Claims”) arising out of any such failure of the Premises to comply with the ADA. Notwithstanding the foregoing or anything to the contrary 
in this Lease, Tenant’s foregoing indemnity obligations shall not apply to any liability arising from noncompliance of the Premises with the ADA where 
such noncompliance existed prior to the date of the Existing Sublease. The provisions of this Section shall survive the expiration or earlier termination of 
this Lease.

5.7 Rules and Regulations, CC&Rs, Parking Facilities and Common Areas.

5.7.1  Tenant  shall  have  the  non-exclusive  right,  in  common  with  others,  to  use  the  Common  Areas,  subject  to  the  Rules  and 
Regulations. The manner in which the Common Areas are maintained and operated shall be at the sole discretion of Landlord (but such maintenance and 
operations must be consistent with Comparable Buildings) and the use thereof shall be subject to the Rules and Regulations, as Landlord may make from 
time to time, subject to Section 5.2.

5.7.2  This  Lease  is  subject  to  any  recorded  covenants,  conditions  or  restrictions  on  the  Project  or  Property  (the  “CC&Rs”),  as  the 
same may be amended, amended and restated, supplemented or otherwise modified from time to time; provided that any such amendments, restatements, 
supplements or modifications do not materially modify Tenant’s rights or obligations hereunder, or materially restrict or impair (other than for a reasonable, 
temporary period) Tenant’s access to the Premises or parking facilities. Tenant shall comply with the CC&Rs.

5.7.3 Tenant shall have a non-exclusive, irrevocable license to use throughout the Lease Term the number of unreserved parking passes 
set forth in Section 11 of the Summary in at such locations in the parking facilities serving the Building as may be determined by Landlord from time to 
time in common with the other occupants of the Building, on an unreserved basis at no cost to Tenant. Tenant shall use only such parking facilities to park 
Tenant’s vehicles. In no event shall Tenant park or store any items other than automotive vehicles at such parking facilities.

5.7.4 Tenant agrees not to unreasonably overburden the parking facilities and agrees to cooperate with Landlord and other tenants in 
the use of the parking facilities. Landlord reserves the right to determine that parking facilities are becoming overcrowded and to limit Tenant’s use thereof 
in a non-discriminatory manner with respect to other tenants of the Project (and provided that Tenant still has the right to the number of unreserved parking 
passes set forth in Section 11 of the Summary). Landlord may reasonably allocate parking spaces among Tenant and other tenants of the Building or the 
Project and Tenant shall be entitled to use throughout the Lease Term the number of unreserved parking passes set forth in Section 11 of the Summary. 
Nothing in this Section, however, is intended to create an affirmative duty on Landlord’s part to monitor parking.

5.7.5 Landlord reserves the right to modify the Common Areas, including the right to add or remove exterior and interior landscaping 
and to subdivide real property, in accordance with the terms and conditions of this Lease. Tenant acknowledges that Landlord specifically reserves the right 
to allow the exclusive use of corridors and restroom facilities located on specific floors to one or more tenants occupying such floors; provided, however, 
that Tenant shall not be deprived of the use of the corridors reasonably required to serve the Premises or of restroom facilities serving the floor upon which 
the Premises are located. Landlord reserves the right to close temporarily, make alterations or additions to, or change the location of elements of the Project 
and the Common Areas. Landlord agrees to use commercially reasonable efforts to mitigate interference with Tenant’s use of and access to the Premises in 
connection with such closures, alterations or additions to the Common Areas.

5.8 Storage Facilities. [***].

6. SERVICES AND UTILITIES

6.1 Standard Tenant Services.  Landlord shall provide the following services during the Lease Term.

6.1.1 HVAC. In accordance with the “Base Building” definition as provided in Section 1 of the Work Letter, the Building shall be 
equipped with a heating and air conditioning (“HVAC”) system serving the Premises (the “BB  HVAC  System”).  Subject  to  limitations  imposed  by  all 
governmental rules, regulations and guidelines applicable thereto, Landlord shall provide BB HVAC System service during the “HVAC System Hours” 
(defined  below).  Landlord  will  operate  the  BB  HVAC  System  for  the  benefit  of  the  Premises  the  hours  of  8:00  A.M.  to  6:00  P.M.  on  Monday  through 
Friday (the “HVAC System Hours”). Tenant shall cooperate fully with Landlord at all times and abide by all regulations and requirements that Landlord 
may reasonably prescribe for the proper functioning and protection of the BB HVAC System. If Tenant requires after-hours operation of the BB HVAC 
System (“Excess Hours”) and Tenant gives Landlord at least twenty-four (24) hours advance notice on a business day, then Landlord shall supply such 
HVAC to Tenant at Landlord’s actual cost (which shall be treated as Additional Rent, but not as an Operating Expense) on a zone-by-zone basis, including 
the cost of increased depreciation on the BB HVAC 

-24-

 
System,  but  excluding  the  cost  of  electricity  to  the  extent  already  paid  for  directly  by  Tenant,  but  including  the  electrical  costs  specified  as  follows; 
provided,  however,  if  Tenant  gives  Landlord  less  than  twenty-four  (24)  hours  advance  notice,  Landlord  will  nevertheless  endeavor  to  accommodate 
Tenant’s request so long as such shorter notice is given on a business day. Landlord shall reasonably and equitably allocate the portion of the electrical costs 
of the BB HVAC System attributable to Tenant’s use of the BB HVAC System for the Excess Hours to Tenant, and Tenant shall pay for the costs of such 
use along with the increased depreciation as set forth above, within thirty (30) days after demand, and as Additional Rent under this Lease (and not as part 
of the Operating Expenses) (the “Extra HVAC Costs”). Notwithstanding anything to the contrary contained in the foregoing, the HVAC Systems Hours 
shall not be applicable to the lab portions of the Premises (located on floors 10, 11 and 12); instead, Landlord shall operate the BB HVAC System as to the 
lab floors on a twenty-four (24) hours per day basis, and Tenant shall have the ability from within the Premises to access thermostats for controlling the 
temperature settings for the HVAC serving the lab floors of the Premises (it being understood that Tenant needs to operate the HVAC, and all other rooftop 
equipment exclusively serving the lab floors, outside of Building Hours and will run HVAC, and all other rooftop equipment exclusively serving the lab 
floors, 24 hours per day), and Tenant shall be liable for the Extra HVAC Costs.

6.1.2 Electricity. Landlord shall provide electrical wiring and facilities for connection to Tenant’s lighting and Tenant’s incidental use 
equipment  as  described  in  Schedule  2  to  Exhibit  B.  Tenant  shall  not  use  combined  electrical  load  for  Tenant’s  incidental  use  equipment  and  Tenant’s 
lighting fixtures in excess of its pro rata share of the capacity of the feeders, which electrical usage shall be subject to Applicable Laws, including Title 24. 
Tenant shall bear the cost of replacement of lamps, starters and ballasts for non-Building standard lighting fixtures within the Premises (Landlord, as part of 
Operating Expenses, will replace Building-standard lamps, starters and ballasts). Tenant shall reasonably cooperate with Landlord at all times and abide by 
all regulations and requirements that Landlord may reasonably prescribe for the proper functioning and protection of the Building Systems. All electricity 
usage at the Project shall be monitored using separate submeters (the “Submetering Equipment”) which shall be (i) installed by Landlord or any tenant, 
for other tenant space in the Project, (ii) installed by Tenant for the Premises (not including the “Building Systems”, as that term is defined in Article 7 of 
this Lease), and (iii) installed by Landlord for the Common Areas and Building Systems. Tenant shall have no obligation to pay for any costs of electricity 
(including as part of Operating Expenses) shown on the Submetering Equipment described in item (i) above. Tenant shall be responsible to pay directly, 
and not as a part of Operating Expenses, for the cost of all electricity shown on the Submetering Equipment described in item (ii) above. The cost of all 
electricity shown on the Submetering Equipment described in item (iii) above (except to the extent included in the Extra HVAC Costs) shall be included in 
Operating  Expenses.  Tenant  may  audit  Landlord’s  readings  of  the  Submetering  Equipment  and  Landlord  shall  deliver  reasonably  detailed  invoices  to 
Tenant reflecting Landlord’s reading of the Submetering Equipment and resulting electricity costs.

6.1.3 Water and Sewer. Landlord shall cause water and sewer to be supplied to the regular Building outlets for drinking, lavatory and 
toilet purposes within the Building and for laboratory purposes within the Premises (to the extent consistent with usage volumes for life science tenants 
within Comparable Buildings). Landlord shall reasonably and equitably allocate the portion of such utilities attributable to Tenant’s direct use to Tenant, 
and Tenant shall pay for the costs of such direct use, within thirty (30) days after demand and as Additional Rent under this Lease (and not as part of the 
Operating Expenses), and other water and sewer costs shall be reasonably and equitably included as part of Operating Expenses, to the extent permitted by 
the terms of Section 4.2.4 above or charged directly to other tenants of the Project. If Landlord determines that Tenant may be using an amount of water in 
excess of its pro rata share, Landlord reserves the right to install submetering equipment, at Tenant’s expense, to monitor Tenant’s usage and bill Tenant for 
such usage. Landlord shall designate the utility providers from time to time.

6.1.4 Gas. Landlord shall cause gas to be supplied to the Project, and Tenant shall be entitled to its pro rata share of gas supplied to the 
Project. The portion of the gas used in connection with the Retail Space shall be separately submetered and paid for directly by such retail tenants. The cost 
of all other gas supplied to the Project shall be included in Operating Expenses. Landlord’s approval shall be required if Tenant desires gas service within 
the Premises. If Landlord approves such request, the cost of installing any equipment and lines necessary for such service shall be at Tenant’s sole cost and 
expense,  including,  without  limitation,  the  cost  of  installing  and  maintaining  submeters  to  monitor  such  gas  usage  within  the  Premises.  Landlord  will 
invoice Tenant periodically for such direct gas use as shown on such submeters (as a direct expense and not part of Operating Expenses) and Tenant shall 
be paid by it within fifteen (15) days following Landlord’s delivery of any such invoice to Tenant.

-25-

 
6.1.5 Janitorial. Landlord shall provide janitorial services for the Common Areas and exterior window washing services, in a manner 
consistent with the Comparable Buildings; but Landlord shall not provide janitorial services for the Premises. Tenant shall perform all janitorial services 
and other cleaning within the Premises in a manner consistent with the standards of other first-class, institutionally owned office/life science buildings in 
the City of San Francisco (“City”) using a janitorial contract approved by Landlord, which approval shall not be unreasonably withheld, conditioned or 
delayed (provided, however, Landlord hereby preapproves AC Janitorial Service and CW Maintenance as janitorial contractors that may be retained by 
Tenant). Without Landlord’s prior consent, Tenant shall not use (and upon notice from Landlord shall cease using) janitorial service providers who would, 
in Landlord’s reasonable and good faith judgment, disturb labor harmony with the workforce or trades engaged in performing other work, labor or services 
in or about the Buildings or the Common Areas.

designated by Landlord (the “Building Hours”) and shall have one (1) elevator available serving each Building at all other times.

6.1.6  Elevator.  Landlord  shall  provide  non-attended  automatic  passenger  elevator  service  during  the  building  hours  reasonably 

6.1.7 Loading Dock.  Landlord  shall  provide  use  of  the  loading  dock  in  the  North  Tower  for  deliveries  to  Tenant,  provided  that  (i) 
Tenant shall schedule its use of such loading dock with Landlord at least 24 hours in advance (provided, however, in the event that Tenant has not given 
such advance notice, Tenant’s use of the loading dock shall be subject to the prior use thereof by users who have scheduled such use in advance), and (ii) 
use of the loading dock is limited to between 6:00 AM and 5:00 PM Monday through Friday (“Loading Dock Hours”), such hours subject to change upon 
written  notice  from  Landlord;  provided,  however,  if  Tenant  requests  access  to  the  loading  dock  outside  of  the  Loading  Dock  Hours,  Tenant  shall  pay 
Landlord an after-hours charge of $50 per visit for Landlord to engage its security personnel in connection with such loading dock access (such after-hours 
charge subject to adjustment by Landlord from time to time). The Loading Dock Hours shall not apply to Tenant’s initial move-in to the Premises and the 
loading dock shall be made available for Tenant’s initial move-in without charge; provided, that Tenant shall reasonably coordinate such initial move-in 
with Landlord.

6.1.8 Risers, Raceways, Shafts, Conduits. Subject to Landlord’s reasonable rules, regulations, and restrictions and the terms of this 
Lease, Landlord shall permit Tenant, at no additional charge to Tenant, to utilize the Building’s risers, raceways, shafts and conduit, provided that there is 
available space in the Building’s risers, raceways, shafts and/or conduit for Landlord’s reasonable use and reasonable use by the other tenants of the Project, 
which availability shall be determined by Landlord in Landlord’s sole discretion. Landlord shall have the right to re- route the planned location of Tenant’s 
cabling in such risers, raceways, shafts and conduit, as determined by Landlord in its reasonable discretion.

6.1.9 Access Control. The Building and Parking Facilities have an access-control system, including, without limitation, door access 
controls, lobby turnstiles and elevator access controls; provided however, the parties acknowledge that the North Lobby is open to the public, and access 
will  not  be  restricted  during  general  business  hours.  Landlord  shall  not  be  obligated  to  provide  any  other  security  equipment.  Notwithstanding  any 
provision to the contrary set forth in this Lease, in no case, shall Landlord be liable for personal injury or property damage for any lack of security in the 
Building or for any error with regard to the admission to or exclusion from the Buildings or Project of any person.

6.1.10 Security Personnel. Landlord shall provide on-site security services, including security personnel in the North Lobby and the 
Parking  Facilities,  consistent  with  the  services  provided  by  landlords  at  Comparable  Buildings  (the  “Security Personnel”),  the  costs  of  which  shall  be 
included  in  Direct  Expenses.  In  addition,  (a)  the  Security  Personnel  shall  be  licensed  and  bonded  and  shall  at  all  times  maintain  any  and  all  required 
licenses or other governmental permits required in connection with any weapons carried by Security Personnel and/or the performance of its duties under 
this Lease and shall at all times conduct themselves in a manner consistent with a first class office and life sciences building project, (b) a commercially 
reasonable background check shall be performed on all Security Personnel, and (c) all of the Security Personnel shall be union labor and comply with the 
Mission Bay Requirements and the Underlying Documents.

6.1.11  Tenant’s  Security  System.  Landlord  hereby  agrees  that  Tenant  shall  have  the  right  to  install  a  card  key  security  system 
(“Tenant’s Security System”) in the Premises and Stairwells on the floors of the Premises and to connect such system to Landlord’s access-control system 
for the Project; provided that Tenant shall work with Landlord to connect Landlord’s existing access card keys for the Project to Tenant’s Security System, 
or, if such 

-26-

 
connection  is  not  possible,  shall  provide  Landlord  with  a  reasonable  number  of  card  keys  for  Landlord’s  access  to  the  Buildings  and/or  the  Premises 
pursuant to the terms of this Lease. Tenant’s Security System shall by subject to Landlord’s prior review and approval (not to be unreasonably withheld), 
and  the  installation  thereof  shall  be  deemed  an  Alteration  and  shall  be  performed  pursuant  to  Article 8  of  this  Lease,  below  or  shall  be  installed  as  an 
Improvement pursuant to the Work Letter. In addition, Tenant shall coordinate the selection, installation and operation of Tenant’s Security System with 
Landlord in order to ensure that Tenant’s Security System is compatible with the Building Systems and permits Landlord to identify any persons entering 
and  exiting  any  Buildings,  and  Tenant  shall  not  be  entitled  to  install  and/or  operate  the  Tenant’s  Security  System  if  Tenant’s  Security  System  does  not 
comply with the foregoing. Tenant shall be solely responsible, at Tenant’s sole cost and expense, for the installation, monitoring, operation and removal of 
Tenant’s Security System.

6.1.12 Access. Subject to Applicable Laws and the other provisions of this Lease, and except in the event of an emergency, Tenant 
shall have access to the above utilities and the Buildings, the Premises and the Common Areas, other than common areas requiring access with a Building 
engineer,  the  Parking  Facilities  and  freight  elevator,  if  any,  twenty-four  (24)  hours  per  day,  seven  (7)  days  per  week,  every  day  of  the  year;  provided, 
however, that Tenant shall pay Landlord’s reasonable out-of-pocket costs that are incurred if Tenant uses the loading dock, mailroom and other limited-
access areas of the Buildings during other than normal Building Hours.

6.1.13 Emergency Generator.  The  Base  Building  has  one  (1)  non-exclusive  emergency  generator  serving  the  North  Complex,  the 
Tenant’s  pro  rata  share  of  which  shall  be  available,  on  a  non-exclusive  basis,  for  connection  to  Tenant’s  standby  equipment  and  systems  (each,  a 
“Generator”).  All  connections  (cables,  cable  trays,  etc.)  (the  “Generator  Facilities”)  from  such  Generator  to  the  Premises  shall  be  located  in  areas 
approved by Landlord, in its sole discretion, and shall comply with Applicable Laws. Commencing on the date that Tenant first connects the Generator 
Facilities to a Generator, as reasonably determined by Landlord, Tenant shall reimburse Landlord within thirty (30) days of request, as Additional Rent, 
Tenant’s pro rata share (based on Tenant’s use of such Generator and use of such Generator by other parties, as reasonably determined by Landlord based 
on the respective connections to such Generator (not the respective rentable square footage of any space leased in the Project by such users)), of all costs 
and expenses incurred by Landlord as a result of or in connection with operation, use, repairs, and maintenance of such Generator, including costs for fuel, 
and  depreciation  (as  reasonably  determined  by  Landlord).  Tenant  acknowledges  that  Landlord  shall  not  be  liable  for  any  damage  that  may  occur  with 
respect to a Generator.

6.1.14 Mailroom. Tenant shall have no access rights to any of the other tenant’s mailrooms located in the Complex. Tenant shall have 
reasonable access rights to the USPS mailroom serving the entire Complex. Tenant shall be solely responsible for collecting deliveries from the loading 
dock in the North Tower (such loading dock access shall be subject to Section 6.1.7 above).

6.2 Interruption of Use. Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent or otherwise (except as specifically 
set  forth  in  this  Section 6.2  below),  for  failure  to  furnish  or  delay  in  furnishing  any  service  (including  telephone  and  telecommunication  services  and 
Generator service), or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by 
breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at 
the Buildings or Project after reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or casualty whatsoever (other than 
the gross negligence or willful misconduct of Landlord, its employees or agents), by act or default of Tenant or other parties, or by any other cause; and 
such failures or delays or diminution shall, except if caused by the gross negligence or willful misconduct of Landlord, its employees or agents, never be 
deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent (except as specifically 
set forth in this Section 6.2 of this Lease) or performing any of its obligations under this Lease. Notwithstanding anything to the contrary contained in the 
foregoing, in the event that there shall be an interruption, curtailment or suspension of any service required to be provided by Landlord pursuant to Section 
6.1 (and no reasonably equivalent alternative service or supply is provided by Landlord) that shall materially interfere with Tenant’s use and enjoyment of a 
material portion of the Premises, and Tenant actually ceases to use the affected portion of the Premises (any such event, a “Service Interruption”), and if 
(i) such Service Interruption shall continue for six (6) consecutive business days following receipt by Landlord of written notice from Tenant describing 
such Service Interruption (the “Service Interruption Notice”), and (ii) such Service Interruption shall not have been caused, in whole or in part, by reasons 
beyond Landlord’s reasonable control or by an act or omission in violation of this Lease by any Tenant Party or by any negligence of Tenant any Tenant 

-27-

 
Parties,  (a  Service  Interruption  that  satisfies  the  foregoing  conditions  being  referred  to  hereinafter  as  a  “Material  Service  Interruption”)  then,  as 
liquidated damages and Tenant’s sole remedy at law or equity, Tenant shall be entitled to an equitable abatement of Base Rent and Tenant’s Share of Direct 
Expenses, based on the nature and duration of the Material Service Interruption, the area of the Premises affected, and the then current Rent amounts, for 
the period that shall begin on the commencement of such Material Service Interruption and that shall end on the day such Material Service Interruption 
shall cease. To the extent a Material Service Interruption is caused by an event covered by Articles 11 or 13 of this Lease, then Tenant’s right to abate rent 
shall be governed by the terms of such Article 11 or 13, as applicable, and the provisions of this paragraph shall not apply.

6.3 Use of Shafts and Utility Connections. Landlord shall have reasonable access, and shall be entitled to allow other tenants of the Buildings, 
if  any,  reasonable  access,  through  existing  Building  shafts  to  other  portions  of  the  Buildings  (including  the  roof,  mechanical  floors  and  tenant  spaces 
(including  the  Premises)),  or  to  utility  connections  outside  the  Buildings,  for  the  installation,  repair,  and  maintenance  of  ducts,  pipes,  connections,  and 
equipment for cables, conduits, transmitters, receivers, and other office, computer, communications and word and data processing equipment and facilities, 
including any technological devices not yet developed, whether similar or dissimilar to the foregoing, which may hereafter become necessary or desirable 
for any permitted use of the Project; provided, however, that to the extent such shafts or utility connections are located within the Premises, such access 
shall not materially and unreasonably interfere with Tenant’s occupancy of the Premises (Landlord’s efforts in such regard will include, where reasonably 
possible, limiting the performance of any such work which might be disruptive to weekends or the evening and the cleaning of any work area prior to the 
commencement of the next business day). To the extent that Landlord installs, maintains, uses, repairs or replaces pipes, cables, ductwork, conduits, utility 
lines,  and/or  wires  through  hung  ceiling  space,  exterior  perimeter  walls  and  column  space,  adjacent  to  and  in  demising  partitions  and  columns,  in  or 
beneath the floor slab or above, below, or through the Premises, then in the course of making any such installation or repair: (x) Landlord shall not reduce 
Tenant’s usable space, except to a de minimus extent, if the same are not installed behind existing walls or ceilings; (y) Landlord shall box in any of the 
same installed adjacent to existing walls with construction materials substantially similar to those existing in the affected area(s) of the Premises; and (z) 
Landlord shall repair all damage caused by the same and restore such area(s) of the Premises to substantially the condition existing immediately prior to 
such work. The terms of this Section 6.3 shall be subject to the terms of Section 29.32 below.

6.4  Supplemental  HVAC.  Subject  to  Landlord’s  prior  consent,  which  consent  shall  not  be  unreasonably  withheld,  conditioned  or  delayed, 
Tenant shall have the right to install a supplemental HVAC equipment serving all or any portion of the Premises (“Supplemental HVAC Equipment”). 
Any Supplemental HVAC Equipment shall be installed pursuant to the terms of Article 8 or the Work Letter, if installed as part of the initial Improvements, 
and  shall  be  deemed  an  Alteration  (or  Improvement,  as  applicable)  for  purposes  of  this  Lease;  provided,  however,  it  shall  be  deemed  reasonable  for 
Landlord to withhold its approval to the extent any such installation would void the warranties of any Building systems or equipment, interfere with other 
tenant’s systems or equipment, or materially interfere with, or materially increase the cost of, Landlord’s maintenance or operation of the Project, unless 
Tenant  agrees  to  pay  for  such  increased  costs,  or  if  any  such  installation  would  violate  Applicable  Laws  or  the  Mission  Bay  Requirements  or  the 
Underlying Documents (as that term is defined in Section 24.4 below). Tenant shall bear all costs of the equipment, and all costs of installation and removal 
thereof.

7. REPAIRS

7.1 Landlord’s Repair Obligations. Landlord shall at all times during the Lease Term maintain in good condition and operating order and in a 
manner reasonably commensurate with the maintenance standards of owners of Comparable Buildings, the structural portions of the Buildings, including, 
without  limitation,  the  foundation,  exterior  walls,  the  structural  portions  of  the  floors  (including  the  floor  slabs),  ceilings,  roof,  columns,  beams,  shafts, 
stairs,  stairwells,  escalators,  elevators,  base  building  restrooms  and  all  Common  Areas  (collectively,  the  “Building Structure”),  and  the  Base  Building 
mechanical,  electrical,  life  safety,  plumbing,  sprinkler,  security  and  HVAC  systems  installed  or  furnished  by  Landlord  (collectively,  the  “Building 
Systems”);  provided,  however,  if  any  repairs  to  the  foregoing  are  required  due  to  the  negligence  or  willful  misconduct  of  Tenant,  Landlord  shall 
nevertheless  make  such  repairs  at  Tenant’s  expense,  or,  if  covered  by  Landlord’s  insurance,  Tenant  shall  only  be  obligated  to  pay  any  deductible  in 
connection therewith. In addition, Landlord shall use commercially reasonable efforts, at all times during the Lease Term, to cause the Building Systems to 
perform in accordance with the design specifications for such equipment. Except as specifically set forth in this Lease to the contrary, Tenant shall not be 
required to repair the 

-28-

 
Building Structure and/or the Building Systems, except to the extent required because of Tenant’s use of the Premises for other than the Permitted Use; 
provided, however, that Landlord shall nevertheless make such repairs at Tenant’s expense, or, if covered by Landlord’s insurance, Tenant shall only be 
obligated to pay any deductible in connection therewith.

7.2 Tenant’s Repair Obligations. Tenant shall, at Tenant’s own expense, keep the Premises, including all improvements, fixtures, furnishings, 
and systems and equipment within the Premises, and any of Tenant’s improvements, property or equipment located outside of the Premises if permitted by 
Landlord in its sole discretion (such items located outside of the Premises, if any, are, collectively, “Tenant’s Off-Premises Equipment”), in good order, 
repair  and  condition  at  all  times  during  the  Lease  Term.  In  addition,  Tenant  shall,  at  Tenant’s  own  expense,  [but  under  the  reasonable  supervision  and 
subject to the prior reasonable approval of Landlord to the extent (i) the cost of such repairs are reasonably expected to exceed $25,000.00, (ii) such repairs 
will affect the Building Structure, Building Systems or equipment, or (iii) such repairs may disturb any other tenants or occupants of the Building], and 
within any reasonable period of time specified by Landlord, promptly and adequately repair all damage to the Premises and replace or repair all damaged, 
broken, or worn fixtures and appurtenances, except for damage caused by ordinary wear and tear and casualty; provided however, that if Tenant fails to 
make  such  repairs  within  applicable  notice  and  cure  periods,  Landlord  may,  but  need  not,  make  such  repairs  and  replacements,  and  Tenant  shall  pay 
Landlord the cost thereof, including a percentage of the cost thereof sufficient to reimburse Landlord for all overhead, general conditions and other costs or 
expenses arising from Landlord’s involvement with such repairs and replacements plus a management fee of [***] of such cost within twenty (20) days 
after being billed for same. Without limitation, Tenant shall be responsible for electrical, plumbing, heating, ventilating and air-conditioning systems and 
other utility services either located within the Premises or serving solely the Premises and located outside of the Premises from the Building connection 
point to the Premises (but only to the extent serving Tenant exclusively) (e.g., any Supplemental HVAC Equipment), and Tenant shall secure, pay for, and 
keep in force contracts with appropriate and reputable service companies reasonably approved by Landlord providing for the regular maintenance of such 
systems.    Subject  to  the  terms  of  Article  27  below,  Landlord  may,  but  shall  not  be  required  to,  enter  the  Premises  at  all  reasonable  times  and  upon 
reasonable prior notice to make such repairs, alterations, improvements or additions to the Premises or to the Project or to any equipment located in the 
Premises as Landlord shall desire or deem necessary or as Landlord may be required to do by governmental or quasi-governmental authority or court order 
or decree. Tenant hereby waives and releases its right to make repairs at Landlord’s expense under Sections 1941 and 1942 of the California Civil Code or 
under  any  similar  law,  statute  or  ordinance  now  or  hereafter  in  effect.  Tenant’s  obligation  hereunder  shall  include  maintenance  and  repair  of  all 
telecommunications wire and cabling with the Building’s network cabling exclusively serving the Premises.

7.3  Tenant/Landlord  Maintenance  Responsibility  Matrix.  To  clarify  the  respective  obligations  of  Tenant  and  Landlord  with  respect  to 
maintenance and repair under this Lease, the matrix attached hereto as Exhibit 7.3 sets forth the respective obligations of Tenant and Landlord with respect 
to the mechanical systems of the Building and other Building Systems and Tenant installed systems identified therein. 

8. ADDITIONS AND ALTERATIONS

8.1  Landlord’s  Consent  to  Alterations.  Tenant  may  not  make  any  improvements,  alterations,  additions  or  changes  to  the  Premises  or  any 
mechanical,  plumbing,  HVAC  facilities  or  other  utility  or  Building  systems  pertaining  to  the  Premises  (collectively,  the  “Alterations”)  without  first 
procuring the prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant not less than twenty (20) business days 
prior to the commencement thereof. Landlord shall not unreasonably withhold or delay its consent to any proposed nonstructural Alterations, provided that 
such Alterations (1) are not visible from the outside of the Building, (2) do not affect the use of or require access to any part of the Building other than the 
Premises, (3) do not do not violate any certificate of occupancy for the Building or any other permits or licenses relating to the Project, (4) do not adversely 
affect any service required to be furnished to Tenant or to any other tenant or occupant of the Building, (5) do not affect any Building systems or Common 
Areas,  (6)  do  not  reduce  the  value  or  utility  of  the  Building,  (7)  do  not  consist  of  painting  the  underside  or  top  of  the  structure  slab,  and  (8)  otherwise 
comply with the Rules and Regulations and this Article 8. Notwithstanding the foregoing, Tenant shall be permitted to make Alterations following ten (10) 
business  days’  notice  to  Landlord,  but  without  Landlord’s  prior  consent,  to  the  extent  that  such  Alterations  (i)  are  purely  cosmetic  in  nature  (such  as 
painting, carpeting and the like), (ii) do not affect the Building Structure, Building systems or equipment, (iii) don not require a building or construction 
permit, (iv) are not visible from the exterior of the Building, (v) do not consist of painting the underside or top of the structure slab, and (vi) cost less than 
$175,000.00 for a particular job of 

-29-

 
work. For the sake of clarity, the construction of the initial improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not 
the terms of this Article 8

Prior  to  commencing  any  Alterations  affecting  air  distribution  or  disbursement  from  MEP  or  other  systems  serving  Tenant  or  the  Building, 
including without limitation the installation of Tenant’s exhaust systems, Tenant shall provide Landlord with a third party report from a consultant, and in a 
form reasonably acceptable to Landlord, showing that such work will not adversely affect the ventilation systems or air quality of the Building (or of any 
other tenant in the Building) and shall, upon completion of such work, provide Landlord with a certification reasonably satisfactory to Landlord from such 
consultant confirming that no such adverse effects have resulted from such work.

8.2 Manner of Construction. Landlord may impose, as a condition of its consent to any and all Alterations or repairs of the Premises or about 
the Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that Tenant 
utilize  for  such  purposes  only  contractors,  subcontractors,  materials,  mechanics  and  materialmen  selected  by  Tenant  and  approved  by  Landlord  (which 
approval shall not be unreasonably withheld, conditioned or delayed) and the requirement that upon Landlord’s request at the time Landlord approves said 
Alterations  (subject  to  the  terms  of  Section  8.5  below),  Tenant  shall,  at  Tenant’s  expense,  remove  such  Alterations  upon  the  expiration  or  any  early 
termination of the Lease Term. Tenant shall construct such Alterations and perform such repairs in a good and workmanlike manner, in conformance with 
any  and  all  Applicable  Laws  and,  where  required  by  Applicable  Law,  pursuant  to  a  valid  building  permit,  issued  by  the  City,  all  in  conformance  with 
Landlord’s construction rules and regulations. In the event Tenant performs any Alterations in the Premises which require or give rise to governmentally 
required changes to the “Base Building,” as that term is defined below, then Landlord shall, at Tenant’s expense, make such changes to the Base Building. 
The “Base Building” shall mean the Building Structure, the Building Systems, including the Building Systems on the floor or floors on which the Premises 
is located as well as the Common Areas. In performing the work of any such Alterations, Tenant shall have the work performed in such manner so as not to 
obstruct access to the Project or any portion thereof, by any other tenant of the Project, and so as not to obstruct the business of Landlord or other tenants in 
the Project. Tenant shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in 
Landlord’s reasonable judgment, would disturb labor harmony with the workforce or trades engaged in performing other work, labor or services in or about 
the Building or the Common Areas. Upon completion of any Alterations (or repairs), Tenant agrees to cause a Notice of Completion to be recorded in the 
office of the Recorder of the County in which the Project is located in accordance with Section 8182 of the Civil Code of the State of California or any 
successor statute, and shall deliver to Landlord final lien waivers from all contractors, subcontractors, design professionals, service providers, suppliers and 
materialmen who performed such work and whose labor, supplies or services give rise to a lien under California law. In addition to Tenant’s obligations 
under Article 9 of this Lease, upon completion of any Alterations, Tenant shall deliver to the Project management office a reproducible copy of the “as 
built” drawings of the Alterations in CAD format as well as copies of all permits, approvals and other documents issued by any governmental agency in 
connection with the Alterations, if applicable.

8.3 Payment  for  Improvements.  If  Tenant  orders  any  work  directly  from  Landlord,  Tenant  shall  pay  to  Landlord  a  percentage  of  the  cost 
thereof sufficient to reimburse Landlord for all overhead, general conditions and other costs or expenses arising from Landlord’s involvement with such 
repairs and replacements plus a management fee of [***] of such cost. If Tenant does not order any work directly from Landlord, Tenant shall reimburse 
Landlord  for  Landlord’s  reasonable,  actual,  out-of-pocket  costs  and  expenses  actually  incurred  in  connection  with  Landlord’s  review  of  any  proposed 
Alterations.  If  payment  is  made  directly  to  contractors,  Tenant  shall,  at  Tenant’s  cost,  comply  with  Landlord’s  requirements  for  final  lien  releases  and 
waivers in connection with Tenant’s payment for work to contractors. For purposes of determining the cost of an Alteration, work done in phases or stages 
shall  be  considered  part  of  the  same  Alteration,  and  any  Alteration  shall  be  deemed  to  include  all  trades  and  materials  involved  in  accomplishing  a 
particular result. 

(i)  Construction Insurance. In addition to the requirements of Article 10 of this Lease, in the event that Tenant makes 
any Alterations, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant or Tenant’s general contractor 
carries “Builder’s  All  Risk”  insurance  in  an  amount  approved  by  Landlord  covering  the  construction  of  such  Alterations,  and  such  other  insurance  as 
Landlord may reasonably require, it being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 of this Lease 
immediately  upon  completion  thereof.  In  connection  with  any  Alterations,  Tenant  shall  cause  any  architect  and  engineer  to  carry  professional  liability 
insurance with limits of not less than $2,000,000 per claim and in the annual aggregate covering professional services performed by the respective party, 
and such coverage 

-30-

 
must be maintained for the greatest period under which a claim may be properly asserted under the applicable statute of limitations or repose. In addition, 
Tenant’s  contractors  and  subcontractors  shall  be  required  to  carry  Commercial  General  Liability  Insurance  in  an  amount  approved  by  Landlord  and 
otherwise in accordance with the requirements of Article 10 of this Lease and such general liability insurance shall name the Landlord Parties (as defined 
below) as additional insureds. Landlord may, in its discretion, require Tenant to obtain and record a statutory form of lien bond, or obtain performance and 
payment bonds, or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations 
and naming Landlord as a co-obligee, in each case in form and substance reasonably satisfactory to Landlord (to the extent that the cost of the work shall 
exceed  $100,000).  In  addition,  Tenant’s  contractors  and  subcontractors  shall  be  required  to  carry  workers  compensation  insurance  with  a  waiver  of 
subrogation in favor of Landlord Parties.

8.4 Landlord’s Property. All Alterations, improvements, fixtures, equipment and/or appurtenances which may be installed or placed in or about 
the Premises, from time to time, shall be at the sole cost of Tenant and shall be and become the property of Landlord [other than Tenant’s trade fixtures and 
moveable equipment paid for solely by Tenant and capable of being removed without damage to the Premises (or, if damage is likely to occur, that Tenant 
will be able to repair and fully restore] and remain in place at the Premises following the expiration or earlier termination of this Lease. Notwithstanding 
the foregoing to the contrary, if requested by Tenant when procuring Landlord’s consent to any Alterations in accordance with Section 8.1 above, Landlord 
will, by written notice to Tenant give Tenant notice as to whether Landlord will (or reserves the right to) require Tenant, at Tenant’s expense, to remove any 
Alterations and/or improvements and/or systems within the Premises (excluding the Tenant Improvements) and to repair any damage to the Premises and 
Building  caused  by  such  removal  and  return  the  affected  portion  of  the  Premises  to  a  building  standard  tenant  improved  condition  as  determined  by 
Landlord.  If  Tenant  fails  to  complete  any  such  removal  and/or  to  repair  any  damage  caused  by  the  removal  of  any  Alterations  and/or  systems  and 
equipment in the Premises and return the affected portion of the Premises to a building standard tenant improved condition as reasonably determined by 
Landlord, Landlord may do so and may charge the actual and reasonable cost thereof to Tenant. Tenant hereby protects, defends, indemnifies and holds 
Landlord harmless from any liability, cost, obligation, expense or claim of lien in any manner relating to the installation, placement, removal or financing 
of any such Alterations, improvements, fixtures and/or equipment in, on or about the Premises (except to the extent resulting from the gross negligence or 
willful misconduct of Landlord or any of the Landlord Parties), which obligations of Tenant shall survive the expiration or earlier termination of this Lease. 
Notwithstanding  anything  to  the  contrary  in  this  Lease,  Tenant  shall  not  be  required  to  remove  any  of  the  Tenant  Improvements  upon  the  expiration  or 
earlier termination of this Lease.

9. COVENANT AGAINST LIENS

Tenant shall keep the Project, the Building and Premises free from any liens or encumbrances arising out of the work performed, materials or 
services furnished or obligations incurred by or on behalf of Tenant (which expressly excludes the Landlord Work), and shall protect, defend, indemnify 
and hold Landlord harmless from and against any claims, liabilities, judgments or costs (including, without limitation, reasonable attorneys’ fees and costs) 
arising out of same or in connection therewith. Tenant shall give Landlord notice at least fifteen (15) days prior to the commencement of any work, services 
or obligations related to the Premises giving rise to any such liens or encumbrances (or such additional time as may be necessary under Applicable Laws) 
to afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility (to the extent applicable pursuant to then Applicable 
Laws).  Tenant  shall  remove  any  such  lien  or  encumbrance  by  statutory  lien  bond  or  otherwise  within  ten  (10)  business  days  after  written  notice  by 
Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for 
investigating the validity thereof. The amount so paid all be deemed Additional Rent under this Lease payable within thirty (30) days after demand, without 
limitation as to other remedies available to Landlord under this Lease. Nothing contained in this Lease shall authorize Tenant to do any act which shall 
subject  Landlord’s  title  to  the  Project,  Buildings  or  Premises  to  any  liens  or  encumbrances  whether  claimed  by  operation  of  law  or  express  or  implied 
contract.

10. INSURANCE

10.1 Indemnification and Waiver. Except to the extent arising from the negligence or willful misconduct of Landlord or any Landlord Parties 
(defined below) but subject to this Section 10.1, to the maximum extent permitted pursuant to Applicable Laws, Tenant hereby assumes all risk of damage 
to property or injury to persons in, upon or about the Premises, the Bicycle Storage Area and any of Tenant’s Off-Premises Equipment from any cause 
whatsoever 

-31-

 
(including, but not limited to, any personal injuries resulting from a slip and fall in, upon or about the Premises) and agrees that, to the extent permitted 
pursuant  to  Applicable  Laws,  Landlord,  its  lenders,  partners,  subpartners  and  their  respective  officers,  agents,  servants,  employees,  and  independent 
contractors (collectively, “Landlord Parties”) shall not be liable for, and are hereby released from any responsibility for, any damage either to person or 
property or resulting from the loss of use thereof, which damage is sustained by Tenant or by other persons claiming through Tenant, except to the extent 
resulting from the gross negligence or willful misconduct of Landlord or any of the Landlord Parties. Tenant shall indemnify, defend, protect, and hold 
harmless the Landlord Parties from any and all loss, cost, damage, injury, expense and liability (including without limitation court costs and reasonable 
attorneys’ fees) during the Lease Term, or any period of Tenant’s occupancy of the Premises prior to the commencement or after the expiration of the Lease 
Term, incurred in connection with or arising from (i) any cause in, on or about the Premises, the Bicycle Storage Area or Tenant’s Off-Premises Equipment 
(including, but not limited to, a slip and fall), provided that the terms of the foregoing indemnity shall not apply to the extent of any gross negligence or 
willful misconduct of Landlord or any of the Landlord Parties, (ii) any negligent acts or omissions of Tenant or of any person claiming by, through or under 
Tenant, or of the contractors, agents, servants, employees, invitees, guests or licensees of Tenant or any such person, in, on or about the Project (including 
without  limitation  on  account  of  Tenant’s  use  of  the  Bicycle  Storage  Area  and  any  of  Tenant’s  Off-Premises  Equipment/Special  Systems),  or  (iii)  any 
breach of the terms of this Lease by Tenant, either prior to, during, or after the expiration of the Lease Term. Should Landlord be named as a defendant in 
any suit brought against Tenant for which Tenant’s indemnity obligation is applicable, Tenant shall pay to Landlord its reasonable and actual out-of-pocket 
costs and expenses incurred in such suit, including without limitation, its actual professional fees such as appraisers’, accountants’ and attorneys’ fees. The 
provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease. Subject to this Section 10.1, Landlord hereby indemnifies 
and  agrees  to  defend,  save  and  hold  Tenant  and  its  partners,  subpartners  and  their  respective  officers,  agents,  servants,  employees,  and  independent 
contractors harmless from and against any and all claims for injury or death to persons or damage to property to the extent resulting from the negligent acts 
or  omissions  of  Landlord  or  any  Landlord  Parties.  Should  Tenant  be  named  as  a  defendant  in  any  suit  brought  against  Landlord  for  which  Landlord’s 
indemnity obligation is applicable, Landlord shall pay to Tenant its reasonable and actual out-of-pocket costs and expenses incurred in such suit, including 
without limitation, its actual professional fees such as appraisers’, accountants’ and attorneys’ fees. Notwithstanding anything to the contrary set forth in 
this Lease, either party’s agreement to indemnify the other party as set forth in this Section 10.1 shall be ineffective to the extent the matters for which the 
indemnitor agreed to indemnify the indemnitee are covered by insurance required to be carried by the indemnitee pursuant to this Lease (or would have 
been  covered  had  the  indemnitee  carried  the  insurance  required).  Further,  Tenant’s  agreement  to  indemnify  Landlord  and  Landlord’s  agreement  to 
indemnify Tenant pursuant to this Section 10.1 are not intended to and shall not relieve any insurance carrier of its obligations under policies required to be 
carried  pursuant  to  the  provisions  of  this  Lease,  to  the  extent  such  policies  cover,  or  if  carried,  would  have  covered  the  matters,  subject  to  the  parties’ 
respective indemnification obligations; nor shall they supersede any inconsistent agreement of the parties set forth in any other provision of this Lease. The 
provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease with respect to any claims or liability arising in connection 
with any event occurring prior to such expiration or termination.

10.2  Tenant’s  Compliance  With  Landlord’s  Property  Insurance.  Tenant  shall,  at  Tenant’s  expense,  comply  with  all  insurance  company 
requirements pertaining to the use of the Premises. If Tenant’s conduct or use of the Premises for any purpose other than the Permitted Use causes any 
increase in the premium for such insurance policies then Tenant shall reimburse Landlord for any such increase. Tenant, at Tenant’s expense, shall comply 
with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any 
similar body.

10.3 Tenant’s Insurance. Tenant shall maintain the following coverages in the following amounts:

10.3.1 Commercial General Liability Insurance on an ISO CG 00 01 occurrence form covering the insured against claims of bodily 
injury,  personal  and  advertising  injury  and  property  damage  (including  loss  of  use  thereof)  arising  out  of  Tenant’s  operations,  products/completed 
operations, and contractual liability including a Broad Form endorsement covering the insuring provisions of this Lease and the performance by Tenant of 
the indemnity agreements set forth in Section 10.1 of this Lease (including products and completed operations coverage) for limits of liability of not less 
than  those  set  forth  below,  which  may  be  accomplished  by  any  combination  of  primary  and  excess  layers,  provided  the  umbrella  sits  excess  to  the 
underlying  commercial  generally  liability,  automobile  liability,  and  employer’s  liability  insurance.  Such  insurance  shall  be  written  on  an  “occurrence” 
basis. Landlord and any other 

-32-

 
party the Landlord so specifies that has a material financial interest in the Project, including Landlord’s managing agent, ground lessor and/or lender, if any, 
shall be named as additional insureds as their interests may appear using Insurance Service Organization’s form CG2011 or a comparable form approved by 
Landlord. The coverage shall also be extended to include damage caused by heat, smoke or fumes from a hostile fire. The policy shall not contain any 
intra-insured exclusions as between insured persons or organizations. Limits of liability insurance shall not be less than the following (provided, however, 
such limits may be achieved through the use of an umbrella/excess policy):

Bodily Injury and
Property Damage Liability

10.3.2 Property Insurance covering (i) all office furniture, business and trade fixtures, office equipment, free-standing cabinet work, 
movable partitions, merchandise and all other items of Tenant’s property on the Premises installed by, for, or at the expense of Tenant, and (ii) the Tenant 
Improvements described in Exhibit 1.1.1-2 and any other tenant improvements that exist in the Premises (excluding the Base Building) as of the Lease 
Commencement  Date  (the  “Original  Improvements”).  Such  insurance  shall  be  written  on  a  Special  Form  basis,  for  the  full  replacement  cost  value 
(subject to reasonable deductible amounts) new, without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses 
of the policies of insurance and shall include coverage for (a) all perils included in the CP 10 30 04 02 Coverage Special Form, (b) water damage from any 
cause  whatsoever,  including,  but  not  limited  to,  sprinkler  leakage,  bursting,  leaking  or  stoppage  of  any  pipes,  explosion,  and  backup  or  overflow  from

116  Stat.  2322),  the  Terrorism  Risk  Insurance  Program  Reauthorization  Act  of  2005  (Pub.  l.  109-144),  and  the  Terrorism  Risk  Insurance  Program 
Reauthorization Act of 2007 (Pub. L. 110-160, 121 Stat. 183), any successor statute or regulation, or is otherwise available at commercially reasonable 
rates) and (d) earthquake insurance. Such insurance shall be written on an “all risks” of physical loss or damage basis, for the full replacement cost value 
(subject to reasonable deductible amounts) new without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses 
of the policies of insurance and shall include coverage for damage or other loss caused by fire or other peril including, but not limited to, vandalism and 
malicious  mischief,  theft,  water  damage  of  any  type,  including  sprinkler  leakage,  bursting  or  stoppage  of  pipes,  and  explosion.  Notwithstanding  the 
foregoing,  Tenant  may  elect  to  self-insure  terrorism  and  earthquake  insurance  required  in  this  Section  10.3.1  and  self-insurance  shall  not  reduce  the 
coverage amounts required to be maintained by Tenant hereunder and any self-insured amount shall be deemed to contain all of the terms and conditions 
applicable to the insurance required in this Lease, including, without limitation, full waiver of subrogation in favor of Landlord.

10.3.3 Business Income Interruption for one (1) year plus Extra Expense insurance in such amounts as will reimburse Tenant for actual 
direct or indirect loss of earnings and continuing expenses, including rent, attributable to the risks outlined in Section 10.3.2 above with a three hundred 
and sixty-five (365) day extended period of indemnity.

10.3.4 Worker’s Compensation and Employer’s Liability with limits not less than $1,000,000 each accident; $1,000,000 disease – each 
employee; and $1,000,000 disease policy limit with minimum limits of not less than $1,000,000 each accident/employee/disease or other similar insurance 
pursuant to all applicable state and local statutes and regulations. The policy will include a waiver of subrogation in favor of the Landlord Parties.

10.3.5 Environmental/Pollution Liability Insurance. Tenant shall procure and maintain during the Lease Term and for no fewer than 
three  (3)  years  thereafter,  a  stand-alone  (covering  pollution  conditions  at  and  migrating  from  the  Project  and/or  the  Project)  pollution  legal  liability 
insurance policy covering all environmental risks of Tenant’s business for claims relating to clean-up, bodily injury, and property damage, with limits of not 
less than Ten Million Dollars ($10,000,000.00) per claim and Ten Million Dollars ($10,000,000.00) in the aggregate, with 

-33-

 
 
 
respect to environmental contamination and pollution caused or made worse by Tenant. Such coverage shall have no exclusions for medical, special or 
biohazardous waste, mold, microbial matter, bacteria, viruses, fungi, infectious disease, or for any materials, solutions, solid, liquid or gas and/or particles 
expected to be handled and/or generated by Tenant Parties in the course of Tenant’s operations and occupancy of the Premises. Such policy shall include (i) 
full terrorism coverage (whether considered certified or non-certified acts), (ii) coverage for any underground storage tanks and/or above-ground storage 
tanks,  where  applicable,  and  (iii)  coverage  for  radioactive  materials  if  such  materials  are  part  of  Tenant’s  operations;  and  (iv)  that  this  Lease  and  the 
indemnification  requirements  herein  are  included  and  scheduled  as  a  lease  contract  on  the  pollution  legal  liability  policy.  In  the  event  of  any 
environmental/pollution  condition  arising  from  Tenant’s  occupancy  or  operations  at  the  Premises,  Tenant  shall  immediately  notify  Landlord.  Tenant’s 
environmental/pollution liability insurance shall be maintained for a period not less than ten (10) years after expiration of this Agreement or such greater 
time provided by the statute of limitation and/or repose.

$1,000,000 combined single limit for bodily injury and property damage.

10.3.6 Commercial automobile liability insurance covering all Owned (if any), Hired, or Non- owned vehicles with limits not less than 

10.3.7 Intentionally Omitted.

10.3.8 Contractor and Vendor Insurance. In addition to the insurance Tenant is required to maintain under this Lease, if Tenant hires or 
brings a contractor or vendor onto the Premises or Building to perform or provide any services or products, Tenant shall have a written agreement with 
vendor  whereby  vendor  will  be  required  to  carry  Commercial  General  Liability  insurance  (subject  to  minimum  limits  of  $1,000,000  per  occurrence, 
$2,000,000 in the general aggregate), $2,000,000 products completed operations, and the same insurance coverages required of Tenant herein for Auto (if 
applicable) and Worker’s Compensation and Employer’s Liability insurance; provided, however, Landlord reserves the right to require greater coverage 
limitations for contractors pursuant to Section 8.4 above. Tenant shall cause written agreement to require each vendor to provide true and complete copies 
of all insurance policies and endorsements to Tenant promptly after Tenant’s request, and Tenant shall deliver the same to Landlord prior to entry onto the 
Premises by such vendors. Tenant shall also require that such vendors’ insurance will meet same additional terms as required of Tenant herein with regards 
to adding Additional Insureds as additional insureds.

Landlord  makes  no  representation  that  the  limits  or  forms  of  coverage  of  insurance  specified  herein  are  adequate  to  cover  Tenant’s  property, 

business operations or obligations under this Lease.

10.4 Form of Policies. The minimum limits of policies of insurance required of Tenant under this Lease shall in no event limit the liability of 
Tenant  under  this  Lease.  Landlord,  its  subsidiaries  and  affiliates,  Landlord’s  property  and/or  development  manager  and  any  other  party  Landlord  so 
specifies, shall be named as an additional insured under the policies listed in Sections 10.3.1, 10.3.2  and  10.3.3  using  Insurance  Service  Organization’s 
form CG2011 or a comparable form approved by Landlord. All insurance policies required to be maintained by Tenant shall (i) cover the liability assumed 
by Tenant under this Lease, including, but not limited to, Tenant’s obligations under Section 10.1 of this Lease; (ii) be issued by an insurance company 
having a rating of not less than A:VIII in Best’s Insurance Guide or which is otherwise acceptable to Landlord and licensed to do business in the State of 
California; (iii) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and is non-contributing with 
any  insurance  required  of  Tenant;  (iv)  be  in  form  and  content  reasonably  acceptable  to  Landlord  (Tenant  shall  provide  full  and  complete  copies  of  any 
policies that Landlord reasonably requests); and (v) provide that said insurer shall endeavor to provide written notice to Landlord and any mortgagee of 
Landlord, to the extent such names are furnished to Tenant prior to the cancellation of such policy. Tenant shall deliver said policy or policies or certificates 
thereof to Landlord on or before the earlier to occur of (A) the Lease Commencement Date, and (B) the date upon which Tenant is first provided access to 
the  Premises,  and  at  least  ten  (10)  days  before  the  expiration  dates  thereof.  In  the  event  Tenant  shall  fail  to  procure  such  insurance,  or  to  deliver  such 
policies or certificate within ten (10) days after written notice from Landlord, Landlord may, at its option, procure such policies for the account of Tenant, 
and the cost thereof shall be paid to Landlord within five (5) days after delivery to Tenant of bills therefor.

10.5 Subrogation.  Landlord  and  Tenant  intend  that  their  respective  property  loss  risks  shall  be  borne  by  reasonable  insurance  carriers  to  the 
extent above provided, and Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their respective insurance carriers in the event 
of a property loss to the extent that such coverage is agreed to be provided hereunder. The parties each hereby waive all rights and claims against each other 
for such losses and waive all rights of subrogation of their respective insurers, provided such waiver of subrogation 

-34-

 
shall not affect the right of the insured to recover thereunder. The parties agree that their respective insurance policies specify now or shall specify that the 
waiver of subrogation shall not affect the right of the insured to recover thereunder. Tenant will cause all subtenants and licensees of the Premises claiming 
by, under, or through Tenant to execute and deliver to Landlord a waiver of claims similar to the waiver in this Section 10.5 and to obtain such waiver of 
subrogation  rights  endorsements.  If  either  party  hereto  fails  to  maintain  the  waivers  set  forth  in  items  (i)  and  (ii)  above,  the  party  not  maintaining  the 
requisite waivers shall indemnify, defend, protect, and hold harmless the other party for, from and against any and all Losses arising out of, resulting from, 
or relating to, such failure.

10.6  Additional  Insurance  Obligations.  Tenant  shall  carry  and  maintain  during  the  entire  Lease  Term,  at  Tenant’s  sole  cost  and  expense, 
increased amounts of insurance and such additional coverages as Landlord may reasonably require; provided, however, that (a) in no event shall such new 
or increased amounts or types of insurance exceed that required of comparable tenants by landlords of the Comparable Buildings and (b) Landlord shall not 
have the right to require that Tenant adjust its insurance coverage more than once in any twenty-four (24) month period, and not during the initial twenty-
four (24) months of the Lease Term.

10.7 Landlord’s Fire and Casualty Insurance. Landlord shall insure the Buildings during the Lease Term against loss or damage due to fire 
and other casualties covered within the classification of fire and extended coverage, vandalism coverage and malicious mischief, sprinkler leakage, water 
damage  and  special  extended  coverage.  Such  coverage  shall  be  in  such  amounts,  from  such  companies,  and  on  such  other  terms  and  conditions,  as 
Landlord  may  from  time  to  time  reasonably  determine.  Landlord  shall  also  carry  rental  loss  insurance.  Additionally,  at  the  option  of  Landlord,  such 
insurance coverage may include the risks of earthquakes and/or flood damage and additional hazards, a rental loss endorsement and one or more loss payee 
endorsements in favor of the holders of any mortgages or deeds of trust encumbering the interest of Landlord in the Project or the ground or underlying 
lessors of the Project, or any portion thereof. Notwithstanding the foregoing provisions of this Section 10.7, the coverage and amounts of insurance carried 
by  Landlord  in  connection  with  the  Buildings  shall,  at  a  minimum,  be  comparable  to  the  coverage  and  amounts  of  insurance  which  are  carried  by 
reasonably prudent landlords of Comparable Buildings (provided that in no event shall Landlord be required to carry earthquake insurance). Tenant shall, at 
Tenant’s expense, promptly following notice, comply with all insurance company requirements pertaining to the use of the Premises. If Tenant’s conduct or 
use of the Premises causes any increase in the premium for such insurance policies then Tenant shall reimburse Landlord for any such increase. Tenant, at 
Tenant’s expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of 
Fire Underwriters) and with any similar body.

11. DAMAGE AND DESTRUCTION

11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises resulting from fire or 
any other casualty. If the Premises or any Common Areas serving or providing access to the Premises shall be damaged by fire or other casualty, Landlord 
will, as soon as reasonably possible following the date of the damage, deliver to Tenant an estimate of the time necessary to repair the damage in question 
such that the Premises may be used by and accessible to Tenant and the Buildings and Common Areas operable in a manner consistent with the operation 
prior to such damage; such notice will be based upon the review and opinions of Landlord’s architect and contractor (“Landlord’s Completion Notice”). 
Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and 
subject  to  all  other  terms  of  this  Article 11,  restore  such  Common  Areas  and  the  Premises  to  substantially  the  same  condition  as  existed  prior  to  the 
casualty, except for modifications required by zoning and building codes and other laws or by the holder of a mortgage on the Building or Project or any 
other modifications to the Common Areas deemed desirable by Landlord, which are consistent with the character of the Project, provided that access to the 
Premises shall not be materially impaired. Upon the occurrence of any damage to the Premises, upon notice (the “Landlord Repair Notice”) to Tenant 
from  Landlord  delivered  on  or  before  the  date  that  is  ninety  (90)  days  after  the  date  of  the  damage,  Tenant  shall  assign  to  Landlord  (or  to  any  party 
designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under Section 10.3.2(ii) of this Lease, and Landlord 
shall repair any injury or damage to the Improvements and the Original Improvements and shall return such Improvements and Original Improvements to 
their original condition (any such work will be competitively bid by Landlord to ensure that Landlord receives commercially reasonable pricing for the 
performance  of  such  work  so  that,  to  the  extent  reasonably  possible,  the  cost  of  such  work  does  not  unnecessarily  exceed  the  proceeds  of  Tenant’s 
insurance); provided that if the cost of such repair by Landlord exceeds the amount of insurance proceeds received by Landlord from Tenant’s insurance 
carrier, as assigned by Tenant, the portion of the cost of such repairs which is not so covered by Tenant’s 

-35-

 
insurance proceeds shall be paid by Tenant to Landlord prior to Landlord’s commencement of repair of the damage. In the event that Landlord does not 
deliver the Landlord Repair Notice within ninety (90) days following the date the casualty becomes known to Landlord, Tenant shall, at its sole cost and 
expense, repair any injury or damage to the Improvements and the Original Improvements installed in the Premises and shall return such Improvements and 
Original Improvements to their original condition, or an alternate condition described by Tenant (but subject to Landlord’s prior written approval). Whether 
or not Landlord delivers a Landlord Repair Notice, prior to the commencement of construction, Tenant shall submit to Landlord, for Landlord’s review and 
approval, all plans, specifications and working drawings relating thereto (it being acknowledged that the cost to prepare such plans may be paid for out of 
the applicable insurance proceeds received by Tenant), and Landlord shall select the contractors to perform such improvement work. Landlord shall not be 
liable  for  any  inconvenience  or  annoyance  to  Tenant  or  its  visitors,  or  injury  to  Tenant’s  business  resulting  in  any  way  from  such  damage  or  the  repair 
thereof; provided however, that if such fire or other casualty shall have damaged the Premises or Common Areas necessary to Tenant’s occupancy, and the 
Premises are not occupied by Tenant as a result thereof, then during the time and to the extent the Premises are unfit for occupancy, the Rent shall be abated 
in  proportion  to  the  ratio  that  the  amount  of  rentable  square  feet  of  the  Premises  which  is  unfit  for  occupancy  for  the  Permitted  Use  bears  to  the  total 
rentable square feet of the Premises; provided, further, however, that if the damage or destruction is due to the negligence or willful misconduct of Tenant 
or any of its agents, employees, contractors, invitees or guests, Tenant shall be responsible for any reasonable, applicable insurance deductible (which shall 
be  payable  to  Landlord  upon  demand,  not  to  materially  exceed  the  levels  of  deductibles  for  such  insurance  then  maintained  by  owners  of  Comparable 
Buildings). In the event that Landlord shall not deliver the Landlord Repair Notice, Tenant’s right to rent abatement pursuant to the preceding sentence 
shall terminate as of the date which is reasonably determined by Landlord to be the date Tenant should have completed repairs to the Premises assuming 
Tenant used reasonable due diligence in connection therewith.

11.2 Landlord’s Option to Repair. Notwithstanding the terms of Section 11.1 of this Lease, Landlord may elect not to rebuild and/or restore the 
Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such termination within ninety (90) days after the date 
of discovery of the damage, such notice to include a termination date giving Tenant ninety (90) days to vacate the Premises, but Landlord may so elect only 
if the Building or Project shall be damaged by fire or other casualty or cause, whether or not the Premises are affected, and one or more of the following 
conditions is present: (i) in Landlord’s reasonable judgment, repairs cannot reasonably be completed within eighteen (18) months after the date of discovery 
of the damage (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Building or Project 
or ground lessor with respect to the Building or Project shall require that the insurance proceeds or any portion thereof be used to retire the mortgage debt, 
or shall terminate the ground lease, as the case may be; (iii) more than One Million Dollars ($1,000,000.00) of the cost of repair of such damage is not fully 
covered  by  Landlord’s  insurance  policies  (unless  such  shortfall  is  a  result  of  Landlord’s  failure  to  maintain  the  insurance  that  Landlord  is  required  to 
maintain  pursuant  to  Section  10.7  below);  (iv)  Landlord  decides  to  rebuild  the  Building  or  Common  Areas  so  that  they  will  be  substantially  different 
structurally or architecturally; (v) the damage occurs during the last twelve (12) months of the Lease Term; provided, however, that if such fire or other 
casualty  shall  have  damaged  the  Premises  or  a  portion  thereof  or  Common  Areas  necessary  to  Tenant’s  occupancy  and  as  a  result  of  such  damage  the 
Premises is unfit for occupancy, and provided that Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided 
above, and either (a) the repairs cannot, in the reasonable opinion of Landlord’s contractor, as set forth in Landlord’s Completion Notice, be completed 
within eighteen (18) months after being commenced, or (b) the damage occurs during the last twelve (12) months of the Lease Term and will reasonably 
require in excess of ninety (90) days to repair, Tenant may elect, no earlier than sixty (60) days after Tenant’s receipt of the Landlord’s Completion Notice 
and  not  later  than  ninety  (90)  days  after  the  date  of  Tenant’s  receipt  of  the  Landlord’s  Completion  Notice,  to  terminate  this  Lease  by  written  notice  to 
Landlord effective as of the date specified in the notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after the date such 
notice is given by Tenant. In addition, if such restoration is not substantially complete on or before the later of (i) the date that occurs eighteen (18) months 
after the date of discovery of the damage, and (ii) the date that occurs ninety (90) days after the expiration of the estimated period of time to substantially 
complete  such  restoration,  as  set  forth  in  Landlord’s  Completion  Notice  (the  “Outside  Restoration  Date”),  then  Tenant  shall  have  the  additional  right 
during the first ten (10) business days of each calendar month following the Outside Restoration Date until such repairs are complete, to terminate this 
Lease by delivery of written notice to Landlord (the “Damage Termination Notice”), which termination shall be effective on a date specified by Tenant in 
such Damage Termination Notice (the “Damage Termination Date”), which Damage Termination Date shall not be less than ten (10) business days, nor 
greater  than  thirty  (30)  days,  following  the  date  such  Damage  Termination  Notice  was  delivered  to  Landlord.  In  the  event  this  Lease  is  terminated  in 
accordance with 

-36-

 
the terms of this Section 11.2, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under 
Tenant’s insurance required under subsections (ii) and (iii) of Section 10.3.2 of this Lease.

11.3 Waiver of Statutory Provisions. The provisions of this Lease, including this Article 11, constitute an express agreement between Landlord 
and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or the Project, and any statute or regulation 
of the State of California, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations 
concerning  damage  or  destruction  in  the  absence  of  an  express  agreement  between  the  parties,  and  any  other  statute  or  regulation,  now  or  hereafter  in 
effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project.

12. NONWAIVER

No provision of this Lease shall be deemed waived by either party hereto unless expressly waived in a writing signed thereby. The waiver by 
either party hereto of any breach of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of same 
or any other term, covenant or condition herein contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of 
any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular Rent so accepted, 
regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No acceptance of a lesser amount than the Rent herein 
stipulated shall be deemed a waiver of Landlord’s right to receive the full amount due, nor shall any endorsement or statement on any check or payment or 
any letter accompanying such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice 
to Landlord’s right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter 
the length of the Lease Term or of Tenant’s right of possession hereunder, or after the giving of any notice shall reinstate, continue or extend the Lease 
Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit, or 
after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect 
said notice, suit or judgment. No payment of Rent by Tenant after a breach by Landlord shall be deemed a waiver of any breach by Landlord.

13. CONDEMNATION

If the whole or substantially all of the Premises, Building or Project shall be taken by power of eminent domain or condemned by any competent 
authority for any public or quasi-public use or purpose, or if all reasonable access to the Building is so taken or condemned, or if Landlord shall grant a 
deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective as of 
the  date  possession  is  required  to  be  surrendered  to  the  authority;  provided,  however,  that  Landlord  shall  only  have  the  right  to  terminate  this  Lease  as 
provided above if Landlord terminates the leases of all other tenants in the Building, if any, similarly affected by the taking and provided further that to the 
extent  that  the  Premises  is  not  adversely  affected  by  such  taking  and  Landlord  continues  to  operate  the  Building  as  office  building  and/or  life  sciences 
building, Landlord may not terminate this Lease. If more than twenty-five percent (25%) of the rentable square feet of the Premises is taken, or if access to 
the Premises is substantially impaired, in each case for a period in excess of one hundred eighty (180) days, Tenant shall have the option to terminate this 
Lease effective as of the date possession is required to be surrendered to the authority. Tenant shall not because of such taking assert any claim against 
Landlord  or  the  authority  for  any  compensation  because  of  such  taking  and  Landlord  shall  be  entitled  to  the  entire  award  or  payment  in  connection 
therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures 
belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, and for moving expenses, so long as 
such claims do not diminish the award available to Landlord, its ground lessor with respect to the Building or Project or its mortgagee, and such claim is 
payable separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken, and this Lease 
shall not be so terminated, the Rent shall be proportionately abated. Notwithstanding anything to the contrary contained in this Article 13, in the event of a 
temporary  taking  of  all  or  any  portion  of  the  Premises  for  a  period  of  twelve  (12)  months  or  less,  and  provided  that  such  temporary  taking  does  not 
materially preclude or unreasonably diminish Tenant’s ability to conduct business from the Premises, then this Lease shall not terminate but the Base Rent 
and Tenant’s Share of Direct Expenses shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet of the 
Premises taken bears to the total rentable 

-37-

 
square feet of the Premises. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil 
Procedure. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking, provided, however, that Tenant shall 
be entitled to a share of the award for any loss of fixtures and improvements and for moving and other reasonable expenses that do not otherwise reduce 
Landlord’s  recovery.  If  this  Lease  does  not  terminate  on  account  of  any  such  eminent  domain  or  condemnation  proceeding,  then  Landlord  shall,  to  the 
extent practicable, restore the affected area of the Premises, Building or Project. In no event shall Landlord have any obligation to undertake restoration on 
account of any condemnation or eminent domain proceeding except to the extent of the award actually received by Landlord. Notwithstanding anything to 
the contrary contained in this Article 13, in the event of a temporary taking of all or any portion of the Premises for a period of twelve (12) months or less, 
then this Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for the period of such taking in proportion to the ratio that the 
amount of rentable square feet of the Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the entire 
award made in connection with any such temporary taking.

14. ASSIGNMENT AND SUBLETTING

14.1 Transfers. Tenant shall not, without the prior written consent of Landlord (except in connection with a Permitted Transfer [as that term is 
defined in Section 14.8 below]), assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any 
interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part 
thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons 
other than Tenant and its employees and contractors (all of the foregoing are hereinafter sometimes referred to collectively as “Transfers” and any person 
to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant desires Landlord’s consent to any 
Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which 
shall not be less than fifteen (15) days nor more than two hundred seventy (270) days after the date of delivery of the Transfer Notice, (ii) a description of 
the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer and the consideration therefor, including 
calculation of the “Transfer Premium”,  as  that  term  is  defined  in  Section 14.3  below,  in  connection  with  such  Transfer,  the  name  and  address  of  the 
proposed  Transferee,  and  a  copy  of  all  existing  executed  and/or  proposed  documentation  pertaining  to  the  proposed  Transfer,  (iv)  current  financial 
statements of the proposed Transferee certified by an officer, partner or owner thereof, business credit and personal references and history of the proposed 
Transferee, (v) any other information reasonably required by Landlord which will enable Landlord to determine the financial responsibility, character, and 
reputation of the proposed Transferee, nature of such Transferee’s business and proposed use of the Subject Space, which information is requested within 
five (5) business days following Tenant’s submission to Landlord of the items described in clauses (i), (ii), (iii), (iv) and (vi) of this Section 14.1, and (vi) 
an executed estoppel certificate from Tenant in the form attached hereto as Exhibit 17. Any Transfer made without Landlord’s prior written consent shall, 
at  Landlord’s  option,  be  null,  void  and  of  no  effect,  and  shall,  at  Landlord’s  option,  constitute  a  default  by  Tenant  under  this  Lease.  Whether  or  not 
Landlord consents to any proposed Transfer, Tenant shall pay Landlord’s reasonable review and processing fees, as well as any reasonable professional fees 
(including, without limitation, attorneys’, accountants’, architects’, engineers’ and consultants’ fees) incurred by Landlord, not to exceed $5,000 in total, 
within thirty (30) days after written request by Landlord.

14.2 Landlord’s Consent. Landlord shall not unreasonably withhold, condition or delay its consent to any proposed sublet of the Subject Space 
or assignment of this Lease on the terms specified in the Transfer Notice and shall grant or withhold such consent within fifteen (15) days following the 
date upon which Landlord receives a “complete” Transfer Notice from Tenant (i.e., a Transfer Notice that includes all documents and information required 
pursuant to Section 14.1 of this Lease). ). If Landlord fails to respond within such fifteen (15) day period, Tenant may send a written “reminder notice”. If 
Landlord fails to respond to such request within five (5) Business Days after delivery of the “reminder notice”, then such nonresponse shall be deemed 
Landlord’s approval of such Transfer request. Without limitation as to other reasonable grounds for withholding consent, the parties hereby agree that it 
shall be reasonable under this Lease and under any Applicable Law for Landlord to withhold consent to any proposed sublet or assignment where one or 
more of the following apply:

business which is not consistent with the quality of the Building or the Project;

14.2.1  The  Transferee  is,  in  Landlord’s  commercially  reasonable  business  judgment,  of  a  character  or  reputation  or  engaged  in  a 

-38-

 
14.2.2 The Transferee intends to use the Subject Space for purposes which are not permitted under this Lease;

14.2.3 The Transferee is either a governmental agency or instrumentality thereof;

14.2.4  The  Transferee  is  a  Tax-Exempt  Entity  (as  defined  in  Exhibit 4.4.3  attached  hereto),  unless  such  Transferee,  at  no  cost  to 
Landlord, complies with and satisfies all of the applicable Mission Bay Requirements relating to a Transfer to a Tax-Exempt Entity as set forth in Exhibit 
4.4.3 attached hereto, to the extent that Landlord continues to be subject to such requirements at the time of such Transfer;

financial stability in light of the responsibilities to be undertaken in connection with the Transfer on the date consent is requested;

14.2.5 The Transferee is not, in Landlord’s commercially reasonable business judgment, a party of reasonable financial worth and/or 

Project a right to cancel its lease; or

14.2.6  The  proposed  Transfer  would  cause  a  violation  of  another  lease  for  space  in  the  Project,  or  would  give  an  occupant  of  the 

14.2.7  Either  the  proposed  Transferee,  or  any  person  or  entity  which  directly  or  indirectly,  controls,  is  controlled  by,  or  is  under 
common control with, the proposed Transferee, is actively negotiating with Landlord or has negotiated with Landlord during the four (4) month period 
immediately preceding the date Landlord receives the Transfer Notice, to lease space in the Project and there is space in the Project then available, or will 
be available timely, for such Transferee within the Project.

14.2.8  In  Landlord’s  reasonable  determination,  the  sub-rent,  additional  rent  or  other  amounts  received  or  accrued  by  Tenant  from 
subleasing, assigning or otherwise Transferring all or any portion of the Premises is based on the income or profits of any person, or the assignment or 
sublease could cause any portion of the amounts received by Landlord pursuant to this Lease to fail to qualify as “rents from real property” within the 
meaning of section 856(d) of the Internal Revenue Code of 1986, as amended (the “Code”), or any similar or successor provision thereto or which would 
cause any other income of Landlord to fail to qualify as income described in section 856(c)(2) of the Code.

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture rights Landlord may have 
under Section 14.4 of this Lease), Tenant may within six (6) months after Landlord’s consent, but not later than the expiration of said six-month period, 
enter  into  such  Transfer  of  the  Premises  or  portion  thereof,  upon  substantially  the  same  terms  and  conditions  as  are  set  forth  in  the  Transfer  Notice 
furnished  by  Tenant  to  Landlord  pursuant  to  Section 14.1  of  this  Lease,  provided  that  if  there  are  any  changes  in  the  terms  and  conditions  from  those 
specified  in  the  Transfer  Notice  (i)  such  that  Landlord  would  initially  have  been  entitled  to  refuse  its  consent  to  such  Transfer  under  this  Section  14.2, 
Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, 
under Section 14.4 of this Lease). Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has 
withheld or delayed its consent in violation of this Section 14.2 or otherwise has breached its obligations under this Article 14, their sole remedies shall be 
a suit for contract damages (other than damages for injury to, or interference with, Tenant’s business including, without limitation, loss of profits, however 
occurring)  or  declaratory  judgment  and  an  injunction  for  the  relief  sought  without  any  monetary  damages,  and  Tenant  hereby  waives  the  provisions  of 
Section 1995.310 of the California Civil Code, or any successor statute, and all other remedies, including, without limitation, any right at law or equity to 
terminate  this  Lease,  on  its  own  behalf  and,  to  the  extent  permitted  under  all  Applicable  Laws,  on  behalf  of  the  proposed  Transferee.  Tenant  shall 
indemnify, defend and hold harmless Landlord from any and all Losses, causes of action and proceedings involving any third party or parties (including 
without  limitation  Tenant’s  proposed  subtenant  or  assignee)  who  claim  they  were  damaged  by  Landlord’s  wrongful  withholding  or  conditioning  of 
Landlord’s consent.

14.3 Transfer Premium. If Landlord consents to a Transfer constituting an assignment of the Lease or a sublease of the Premises, as a condition 
thereto which the parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any “Transfer Premium”, as that term is defined 
in this Section 14.3, received by Tenant from such Transferee (other than any Permitted Transferee). “Transfer Premium” shall mean all rent, additional 
rent or other consideration received by such Transferee in connection with the Transfer in excess of the Rent and Additional Rent payable by Tenant under 
this Lease during the term of the Transfer on a per rentable square 

-39-

 
foot  basis  if  less  than  all  of  the  Premises  is  transferred,  after  deducting  the  reasonable  third  party  expenses  incurred  by  Tenant  for  (i)  any  design  and 
construction costs incurred on account of changes, alterations and improvements to the Premises in connection with the Transfer, (ii) any free base rent and 
tenant improvement allowances reasonably provided to the Transferee in connection with the Transfer (provided that such free rent and tenant improvement 
allowances  shall  be  deducted  only  to  the  extent  the  same  is  included  in  the  calculation  of  total  consideration  payable  by  such  Transferee),  (iii)  any 
brokerage commissions and marketing costs in connection with the Transfer, and (iv) legal fees and disbursements reasonably incurred in connection with 
the  Transfer  (collectively,  “Tenant’s  Subleasing  Costs”). “Transfer Premium”  shall  also  include,  but  not  be  limited  to,  any  lump  sum  payment,  key 
money, bonus money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market 
value  for  services  rendered  by  Tenant  to  Transferee  or  for  assets,  fixtures,  inventory,  equipment,  or  furniture  (other  than  Tenant  Improvements  and 
Alterations) transferred by Tenant to Transferee in connection with such Transfer. For purposes of calculating any such effective rent all such concessions 
shall be amortized on a straight-line basis over the relevant term. The determination of the amount of Landlord’s applicable share of the Transfer Premium 
shall  be  made  on  a  monthly  basis  as  rent  or  other  consideration  is  received  by  Tenant  under  the  Transfer.  No  Transfer  Premium  shall  be  payable  in 
connection with any Permitted Transfer.

14.4  Landlord’s  Option  as  to  Subject  Space.  Notwithstanding  anything  to  the  contrary  contained  in  this  Article  14,  in  the  event  Tenant 
contemplates a Transfer involving either (1) more than two (2) full floors of the Premises for a term that is either (i) more than five (5) years, or (ii) extends 
into any portion of the final three (3) years of the Lease Term, or (2) at least one (1) full floor at any time within the final three (3) years of the Lease Term, 
Tenant shall give Landlord notice (the “Intention to Transfer Notice”) of such contemplated Transfer (whether or not the contemplated Transferee or the 
terms of such contemplated Transfer have been determined). The Intention to Transfer Notice shall specify the portion of and amount of rentable square 
feet  of  the  Premises  which  Tenant  intends  to  Transfer  (the  “Contemplated  Transfer  Space”),  the  contemplated  date  of  commencement  of  the 
Contemplated Transfer (the “Contemplated Effective Date”), and the contemplated length of the term of such contemplated Transfer, and shall specify 
that  such  Intention  to  Transfer  Notice  is  delivered  to  Landlord  pursuant  to  this  Section  14.4  in  order  to  allow  Landlord  to  elect  to  recapture  the 
Contemplated Transfer Space. Thereafter, Landlord shall have the option, by giving written notice to Tenant (a “Recapture Notice”) within thirty (30) days 
after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. Such recapture shall cancel and terminate this Lease with 
respect to such Contemplated Transfer Space as of the Contemplated Effective Date. In the event of a recapture by Landlord, if this Lease shall be canceled 
with respect to less than the entire Premises, the Rent reserved herein shall be prorated on the basis of the number of rentable square feet retained by Tenant 
in proportion to the number of rentable square feet contained in the Premises, and this Lease as so amended shall continue thereafter in full force and effect, 
and upon request of either party, the parties shall execute written confirmation of the same. If Landlord declines, or fails to elect in a timely manner to 
recapture the Contemplated Transfer Space under this Section 14.4, then, subject to the other terms of this Article 14, for a period of six (6) months (the 
“Six-Month Period”) commencing on the last day of such thirty (30) day period, Landlord shall not have any right to recapture the Contemplated Transfer 
Space  with  respect  to  any  Transfer  made  during  the  Six  Month  Period,  provided  that  any  such  Transfer  is  substantially  on  the  terms  set  forth  in  the 
Intention to Transfer Notice, and provided further that any such Transfer shall be subject to the remaining terms of this Article 14. If such a Transfer is not 
so  consummated  within  the  Six-Month  Period  (or  if  a  Transfer  is  so  consummated,  then  upon  the  expiration  of  the  term  of  any  Transfer  of  such 
Contemplated Transfer Space consummated within such Six-Month Period), Tenant shall again be required to submit a new Intention to Transfer Notice to 
Landlord  with  respect  any  contemplated  Transfer  of  the  Contemplated  Transfer  Space,  as  provided  above  in  this  Section  14.4.  Notwithstanding  the 
foregoing to the contrary, Tenant may, within ten (10) days following receipt of any Recapture Notice, rescind the Intention to Transfer Notice (and thereby 
negate the recapture of the Contemplated Transfer Space) to which it applies provided that Tenant does not proceed with the contemplated Transfer giving 
rise to the applicable Intention to Transfer Notice.

14.5 Effect of Transfer. If Landlord consents to a Transfer, (i) the terms and conditions of this Lease shall in no way be deemed to have been 
waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to 
Landlord, promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, 
(iv) Tenant shall furnish upon Landlord’s request a complete statement, certified by an independent certified public accountant, or Tenant’s chief financial 
officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer, and (v) no Transfer relating 
to this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall relieve Tenant or any guarantor of the Lease 
from any 

-40-

 
liability under this Lease, including, without limitation, in connection with the Subject Space. Landlord or its authorized representatives shall have the right 
at all reasonable times and upon reasonable prior notice to audit the books, records and papers of Tenant relating to any Transfer at Tenant’s office, and 
shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days 
after demand, pay the deficiency, and if understated by more than two percent (2%), Tenant shall pay Landlord’s costs of such audit.

14.6 Sublease/Transfer Restrictions. Notwithstanding anything contained herein to the contrary and without limiting the generality of Section 
14.1  above,  Tenant  shall  not:  (a)  sublet  all  or  part  of  the  Premises  or  assign  or  otherwise  Transfer  this  Lease  on  any  basis  such  that  the  rental  or  other 
amounts to be paid by the subtenant or assignee thereunder would be based, in whole or in part, on the income or profits derived by the business activities 
of the subtenant or assignee; (b) sublet all or part of the Premises or assign this Lease to any person or entity in which, under Section 856(d)(2)(B) of the 
Code, Longfellow Atlantic REIT, Inc., a Delaware corporation (the “Company”), or any affiliate of the Company owns, directly or indirectly (by applying 
constructive ownership rules set forth in Section 856(d) (5) of the Code), a ten percent (10%) or greater interest; or (c) sublet all or part of the Premises or 
assign this Lease in any other manner or otherwise derive any income which could cause any portion of the amounts received by Landlord pursuant hereto 
or any sublease to fail to qualify as “rents from real property” within the meaning of Section 856(d) of the Code, or which could cause any other income 
received by Landlord to fail to qualify as income described in Section 856(c) (2) of the Code. The requirements of this Section 14.4 shall likewise apply to 
any further subleasing, assignment or other Transfer by any subtenant or assignee. All references herein to Section 856 of the Code also shall refer to any 
amendments thereof or successor provisions thereto.

14.7 Occurrence of Default. Any Transfer hereunder shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be 
terminated during the term of any Transfer, Landlord shall have the right to (and each sublease shall provide Landlord with the ability to): (i) treat such 
Transfer  as  cancelled  and  repossess  the  Subject  Space  by  any  lawful  means,  or  (ii)  require  that  such  Transferee  attorn  to  and  recognize  Landlord  as  its 
landlord  under  any  such  Transfer.  If  Tenant  shall  be  in  default  under  this  Lease  beyond  any  applicable  notice  and  cure  periods,  Landlord  is  hereby 
irrevocably  authorized,  as  Tenant’s  agent  and  attorney-in-fact,  to  direct  any  Transferee  to  make  all  payments  under  or  in  connection  with  the  Transfer 
directly to Landlord (which Landlord shall apply towards Tenant’s obligations under this Lease) until such default is cured. Such Transferee shall rely on 
any  representation  by  Landlord  that  Tenant  is  in  default  hereunder,  without  any  need  for  confirmation  thereof  by  Tenant.  Upon  any  assignment,  the 
assignee  shall  assume  in  writing  all  obligations  and  covenants  of  Tenant  thereafter  to  be  performed  or  observed  under  this  Lease.  No  collection  or 
acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this Article 14 or the approval of any Transferee or a 
release  of  Tenant  from  any  obligation  under  this  Lease,  whether  theretofore  or  thereafter  accruing.  In  no  event  shall  Landlord’s  enforcement  of  any 
provision of this Lease against any Transferee be deemed a waiver of Landlord’s right to enforce any term of this Lease against Tenant or any other person. 
If Tenant’s obligations hereunder have been guaranteed, Landlord’s consent to any Transfer shall not be effective unless the guarantor also consents to such 
Transfer.

14.8 Non-Transfers. Notwithstanding anything to the contrary contained in this Article 14, (i) an assignment or subletting of all or a portion of 
the  Premises  to  an  affiliate  of  Tenant  (an  entity  which  is  controlled  by,  controls,  or  is  under  common  control  with,  Tenant),  (ii)  an  assignment  of  the 
Premises to an entity which acquires all or substantially all of the assets or beneficial interests (partnership, stock or other) of Tenant, (iii) an assignment of 
the Premises to an entity which is the resulting entity of a merger or consolidation of Tenant (or a transaction where Tenant is the surviving corporation of 
the merger), or (iv) or any other transfer of Tenant’s stock, on a nationally- recognized stock exchange (any of the foregoing, a “Permitted Transferee”), 
shall  not  be  deemed  a  Transfer  under  this  Article  14,  provided  that  (A)  except  in  the  case  of  clause  (i)  above,  Tenant  notifies  Landlord  of  any  such 
assignment or sublease and promptly supplies Landlord with any documents or information requested by Landlord regarding such assignment or sublease 
or such affiliate, (B) such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease, (C) with respect to clause (i), such 
Permitted Transferee shall be of a character and reputation consistent with the quality of the Building, and (D) with respect to an assignment to a Permitted 
Transferee  or  a  Transfer  pursuant  to  clauses  (i),  (ii)  or  (iii)  above,  the  resulting  Tenant  under  this  Lease  shall  have  a  tangible  net  worth  (not  including 
goodwill as an asset) computed in accordance with generally accepted accounting principles (“Net Worth”) at least equal to the Net Worth of Tenant on the 
day  that  is  [three  (3)]  months  prior  to  the  effective  date  of  such  assignment  or  sublease.  An  assignee  of  Tenant’s  entire  interest  that  is  also  a  Permitted 
Transferee may also be known as a “Permitted Assignee”. “Control”, as used in this Section 14.8, shall mean the ownership, 

-41-

 
directly or indirectly, of at least fifty-one percent (51%) of the voting securities of, or possession of the right to vote, in the ordinary direction of its affairs, 
of at least fifty-one percent (51%) of the voting interest in, any person or entity and the ability to direct the day-to-day affairs of such person or entity. No 
such permitted assignment or subletting or other Transfer permitted with or without Landlord’s consent pursuant to this Article 14 shall serve to release 
Tenant  from  any  of  its  obligations  under  this  Lease.  Landlord  acknowledges  that,  as  of  the  date  hereof,  Tenant’s  stock  is  traded  on  a  public  exchange 
(NASDAQ:  VIR).  For  the  avoidance  of  doubt,  so  long  as  Tenant’s  stock  is  traded  on  a  public  exchange,  no  sale,  buy-back,  split  or  other  transfer 
whatsoever of Tenant’s stock shall be deemed a “Transfer” under this Lease.

15. SURRENDER OF PREMISES; OWNERSHIP AND REMOVAL OF TRADE FIXTURES

15.1 Surrender of Premises. No act or thing done by Landlord or any agent or employee of Landlord during the Lease Term shall be deemed to 
constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord. The delivery of 
keys to the Premises to Landlord or any agent or employee of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, 
whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at any 
reasonable  time  upon  request  until  this  Lease  shall  have  been  properly  terminated.  The  voluntary  or  other  surrender  of  this  Lease  by  Tenant,  whether 
accepted  by  Landlord  or  not,  or  a  mutual  termination  hereof,  shall  not  work  a  merger,  and  at  the  option  of  Landlord  shall  operate  as  an  assignment  to 
Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such sublessees or subtenancies.

15.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant 
shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in as good order and condition as when Tenant 
took  possession  and  as  thereafter  improved  by  Landlord  and/or  Tenant,  reasonable  wear  and  tear,  casualty  and  repairs  which  are  specifically  made  the 
responsibility  of  Landlord  hereunder  excepted.  Upon  such  expiration  or  termination,  Tenant  shall,  without  expense  to  Landlord,  remove  or  cause  to  be 
removed from the Premises all Alterations that Tenant is required to remove in accordance with Section 8.3 of this Lease, any debris and rubbish, and such 
items of furniture, equipment, free- standing cabinet work, movable partitions and other articles of personal property, including all Lines, owned by Tenant 
or installed or placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant (collectively, “Tenant’s 
Property”), as Landlord may, in its sole discretion, require to be removed (provided that Tenant, in its sole discretion, may remove all of Tenant’s personal 
property and trade fixtures, at any time, regardless of any such election by Landlord), and Tenant shall repair at its own expense all damage to the Premises 
and Building resulting from such removal. Tenant’s personal property includes only those items that are not built into the Premises and that have not been 
constructed or installed by Landlord.

15.3 Environmental Assessment. Prior to the expiration of the Lease (or within thirty (30) days after any earlier termination), Tenant shall clean 
and  otherwise  decommission  all  interior  surfaces  (including  floors,  walls,  ceilings,  and  counters),  piping,  supply  lines,  waste  lines  and  plumbing  in  or 
serving the Premises, and all exhaust or other ductwork in or serving the Premises, in each case that has carried, released or otherwise been exposed to any 
Hazardous  Materials  due  to  Tenant’s  use  or  occupancy  of  the  Premises,  and  shall  otherwise  clean  the  Premises  so  as  to  permit  the  Environmental 
Assessment  called  for  by  this  Section 15.3  to  be  issued.  Prior  to  the  expiration  of  this  Lease  (or  within  thirty  (30)  days  after  any  earlier  termination), 
Tenant, at Tenant’s expense, shall obtain for Landlord a report (an “Environmental Assessment”) addressed to Landlord (and, at Tenant’s election, Tenant) 
by a reputable licensed environmental engineer or industrial hygienist that is designated by Tenant and acceptable to Landlord in Landlord’s reasonable 
discretion, which report shall be based on the environmental engineer’s inspection of the Premises and shall state, to Landlord’s reasonable satisfaction, that 
(a)  the  Hazardous  Materials  described  in  the  first  sentence  of  this  paragraph,  to  the  extent,  if  any,  existing  prior  to  such  decommissioning,  have  been 
removed in accordance with Applicable Laws; (b) all Hazardous Materials described in the first sentence of this paragraph, if any, have been removed in 
accordance with Applicable Laws from the interior surfaces of the Premises (including floors, walls, ceilings, and counters), piping, supply lines, waste 
lines  and  plumbing,  and  all  such  exhaust  or  other  ductwork  in  the  Premises,  may  be  reused  by  a  subsequent  tenant  or  disposed  of  in  compliance  with 
Applicable Laws without incurring special costs or undertaking special procedures for demolition, disposal, investigation, assessment, cleaning or removal 
of such Hazardous Materials and without giving notice in connection with such Hazardous Materials; and (a) the Premises may be reoccupied for office, 
research  and  development,  or  laboratory  use,  demolished  or  renovated  without  incurring  special  costs  or  undertaking  special  procedures  for  disposal, 
investigation, assessment, cleaning or 

-42-

 
removal  of  Hazardous  Materials  described  in  the  first  sentence  of  this  paragraph  and  without  giving  notice  in  connection  with  Hazardous  Materials. 
Further, for purposes of clauses (b) and (c), “special costs” or “special procedures” shall mean costs or procedures, as the case may be, that would not be 
incurred but for the nature of the Hazardous Materials as Hazardous Materials instead of non-hazardous materials. The report shall also include reasonable 
detail concerning the clean-up measures taken, the clean-up locations, the tests run and the analytic results. Tenant shall submit to Landlord the identity of 
the applicable consultants and the scope of the proposed Environmental Assessment for Landlord’s reasonable review and approval at least 30 days prior to 
commencing the work described therein or at least forty-five (45) days prior to the expiration of the Lease Term, whichever is earlier.

If Tenant fails to perform its obligations under this Section 15.3, without limiting any other right or remedy, Landlord may, on five (5) business 
days’ prior written notice to Tenant perform such obligations at Tenant’s expense if Tenant has not commenced to do so within said five day period, and 
Tenant shall within ten (10) days of written demand (together with supporting documentation) reimburse Landlord for all reasonable out-of-pocket costs 
and  expenses  incurred  by  Landlord  in  connection  with  such  work.  Tenant’s  obligations  under  this  Section  15.3  shall  survive  the  expiration  or  earlier 
termination of this Lease. In addition, at Landlord’s election, Landlord may inspect the Premises and/or the Project for Hazardous Materials at Landlord’s 
cost and expense within sixty (60) days of Tenant’s surrender of the Premises at the expiration or earlier termination of this Lease. Tenant shall pay for all 
such costs and expenses incurred by Landlord in connection with such inspection if such inspection reveals that a release or threat of release of Hazardous 
Materials exists at the Project or Premises as a result of the acts or omission of Tenant, its officers, employees, contractors, and agents (except to the extent 
resulting from (i) Landlord’s Hazardous Materials, or (ii) the acts or omissions of Landlord or Landlord’s agents, employees or contractors).

16. HOLDING OVER

If  Tenant  holds  over  after  the  expiration  of  the  Lease  Term  or  earlier  termination  thereof,  with  the  express  written  consent  of  Landlord,  such 
tenancy shall be from month-to-month only and shall not constitute a renewal hereof or an extension for any further term. If Tenant holds over after the 
expiration of the Lease Term of earlier termination thereof, without the express written consent of Landlord, such tenancy shall be deemed to be a tenancy 
at sufferance only and shall not constitute a renewal hereof or an extension for any further term. In either case, Base Rent shall be payable at a daily rate 
equal to (i) one hundred fifty percent (150%) of the Base Rent applicable during the last rental period of the Lease Term for the first (1st) two (2) months of 
such holdover, and (ii) two hundred percent (200%) thereafter plus one hundred percent (100%) of all Additional Rent. Such month-to-month tenancy or 
tenancy by sufferance, as the case may be, shall be subject to every other applicable term, covenant and agreement contained herein. Nothing contained in 
this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to 
surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this 
Article 16  shall  not  be  deemed  to  limit  or  constitute  a  waiver  of  any  other  rights  or  remedies  of  Landlord  provided  herein  or  at  law.  If  Tenant  fails  to 
surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall 
protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, 
including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender and/or any 
lost profits and consequential or indirect damages to Landlord resulting therefrom. Tenant agrees that any proceedings necessary to recover possession of 
the Premises, whether before or after expiration of the Lease Term, shall be considered an action to enforce the terms of this Lease for purposes of the 
awarding of any attorney’s fees in connection therewith.

17. ESTOPPEL CERTIFICATES

Within ten (10) business days following a request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel 
certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit 17 attached hereto (or such other commercially reasonable form 
as may be reasonably required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto 
that  may  exist  at  that  time,  and  shall  also  contain  any  other  information  reasonably  requested  by  Landlord  or  Landlord’s  mortgagee  or  prospective 
mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. Tenant shall execute 
and  deliver  whatever  other  commercially  reasonable  instruments  may  be  reasonably  required  for  such  purposes.  Failure  of  Tenant  to  timely  execute, 
acknowledge and deliver such estoppel certificate or other instruments shall constitute an acceptance of the 

-43-

 
Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception. At any time during 
the Lease Term (but not more than twice per year, provided Tenant is not in default hereunder beyond applicable notice and cure periods), but only in the 
case of (i) a default of Tenant hereunder, (ii) a proposed sale or refinancing of the Project, or (iii) a proposed Permitted Transfer by Tenant, Landlord may 
require Tenant to provide Landlord with a current financial statement and financial statements of the two (2) years prior to the current financial statement 
year. Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be 
audited  by  an  independent  certified  public  accountant.  If  no  audited  financial  statement  is  prepared,  such  statement  will  be  certified  by  the  CFO  or 
Treasurer of Tenant. Notwithstanding anything to the contrary contained in this Section 17, if Tenant is publicly traded on a nationally recognized stock 
exchange, Tenant will not be required to deliver to Landlord financial statements as and when those documents are publicly available.

18. SUBORDINATION

This Lease shall be subject and subordinate to all future ground or underlying leases of the Building or Project and to the lien of any mortgage, 
trust  deed  or  other  encumbrances  now  or  hereafter  in  force  against  the  Building  or  Project  or  any  part  thereof,  if  any,  and  to  all  renewals,  extensions, 
modifications,  consolidations  and  replacements  thereof,  and  to  all  advances  made  or  hereafter  to  be  made  upon  the  security  of  such  mortgages  or  trust 
deeds,  unless  the  holders  of  such  mortgages,  trust  deeds  or  other  encumbrances,  or  the  lessors  under  such  ground  lease  or  underlying  leases  require  in 
writing that this Lease be superior thereto; provided that, for so long as Tenant is not in default hereunder, Tenant’s occupancy of the Premises shall not be 
disturbed. Tenant covenants and agrees that in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu thereof (or if 
any ground lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors thereto upon any 
such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so requested to do so by such purchaser or lienholder or ground lessor; provided 
that, for so long as Tenant is not in default hereunder, Tenant’s occupancy of the Premises shall not be disturbed. Notwithstanding any other provision of 
this Lease to the contrary, no holder of any such mortgage, trustee deed or other encumbrance and no such ground lessor, shall be obligated to perform or 
liable in damages for failure to perform any of Landlord’s obligations under this Lease unless and until such holder shall foreclose such mortgage, trust 
deed or other encumbrance, or the lessors under such ground lease or underlying leases otherwise acquire title to the Property, and then shall only be liable 
for  Landlord’s  obligations  arising  or  accruing  after  such  foreclosure  or  acquisition  of  title,  provided  the  foregoing  shall  not  release  any  such  holder  or 
ground  lessor  from  performing  ongoing  obligations  of  Landlord  from  and  after  the  date  of  such  foreclosure  or  acquisition  of  title,  such  as  repair  and 
maintenance obligations. No such holder shall ever be obligated to perform or be liable in damages for any of Landlord’s obligations arising or accruing 
before  such  foreclosure  or  acquisition  of  title.  Tenant  shall,  within  ten  (10)  business  days  of  request  by  Landlord,  execute  a  commercially  reasonable 
subordination,  non-disturbance  and  attornment  agreement  as  Landlord  may  reasonably  deem  necessary  to  evidence  or  confirm  the  subordination  or 
superiority  of  this  Lease  to  any  such  mortgages,  trust  deeds,  ground  leases  or  underlying  leases.  Tenant  waives  the  provisions  of  any  current  or  future 
statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations 
of Tenant hereunder in the event of any foreclosure proceeding or sale.

Landlord’s interest herein may be assigned as security at any time to any Mortgagee. Notwithstanding the foregoing or anything to the contrary 
herein, no Mortgagee succeeding to the interest of Landlord hereunder shall be (i) liable in any way to Tenant for any act or omission, neglect or default on 
the part of Landlord under this Lease, (ii) responsible for any monies owing by or on deposit with Landlord to the credit of Tenant (except to the extent any 
such  deposit  is  actually  received  by  such  mortgagee  or  ground  lessor),  (iii)  subject  to  any  counterclaim  or  setoff  which  theretofore  accrued  to  Tenant 
against Landlord, (iv) bound by any amendment or modification of this Lease subsequent to such mortgage, or by any previous prepayment of Rent for 
more  than  one  (1)  month,  which  was  not  approved  in  writing  by  the  Mortgagee,  (v)  liable  beyond  such  Mortgagee’s  interest  in  the  Project,  or  (vi) 
responsible for the payment or performance of any work to be done by Landlord under this Lease to render the Premises ready for occupancy by Tenant or 
for the payment of any tenant improvements allowances. Nothing in clause (i), above, shall be deemed to relieve any Mortgagee succeeding to the interest 
of Landlord hereunder of its obligation to comply with the obligations of Landlord under this Lease from and after the date of such succession.

No Mortgagee shall, either by virtue of the Mortgage or any assignment of leases executed by Landlord for the benefit of such Mortgagee, be or 
become  a  mortgagee  in  possession  or  be  or  become  subject  to  any  liability  or  obligation  under  the  Lease  or  otherwise  until  such  Mortgagee  shall  have 
acquired the interest of Landlord in the 

-44-

 
Property, by foreclosure or otherwise, or in fact have taken possession of the Property as a mortgagee in possession and then such liability or obligation of 
Mortgagee under the Lease shall extend only to those liability or obligations accruing subsequent to the date that such Mortgagee has acquired the interest 
of Landlord in the Premises, or in fact taken possession of the Property as a mortgagee in possession.

19. DEFAULTS; REMEDIES

19.1 Events of Default. The occurrence of any of the following shall constitute a default of this Lease by Tenant:

and such failure shall continue for five (5) days after written notice of such failure is given to Tenant; or

19.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or any part thereof, when due 

19.1.2 Except where a specific time period is otherwise set forth for Tenant’s performance in this Lease, in which event the failure to 
perform by Tenant within such time period shall be a default by Tenant under this Section 19.1.2, any failure by Tenant to observe or perform any other 
provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice 
thereof from Landlord to Tenant; provided that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day period, 
Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure 
such default; or

19.1.3 Abandonment of the Premises by Tenant pursuant to California Civil Code Section 1951.3; or

failure continues for more than two (2) business days after written notice from Landlord; or

19.1.4 The failure by Tenant to observe or perform according to the provisions of Articles 5, 10, 14, 17 or 18 of this Lease where such 

19.1.5  If  a  receiver,  guardian,  conservator,  trustee  in  bankruptcy  or  similar  officer  shall  be  appointed  by  a  court  of  competent 
jurisdiction  to  take  charge  of  all  or  any  part  of  Tenant’s  or  any  guarantor’s  property  and  such  appointment  is  not  discharged  within  ninety  (90)  days 
thereafter  or  if  a  petition  including,  without  limitation,  a  petition  for  reorganization  or  arrangement  is  filed  by  Tenant  or  any  guarantor  under  any 
bankruptcy law or is filed against Tenant or any guarantor and, in the case of a filing against Tenant only, the same shall not be dismissed within ninety (90) 
days from the date upon which it is filed.

The notice periods provided herein are in lieu of, and not in addition to, any notice periods provided by law.

19.2 Remedies Upon Default. Upon the occurrence of any event of default by Tenant beyond applicable notice and cure periods, Landlord shall 
have,  in  addition  to  any  other  remedies  available  to  Landlord  at  law  or  in  equity  (all  of  which  remedies  shall  be  distinct,  separate  and  cumulative),  the 
option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand 
whatsoever. Tenant hereby waives, for Tenant and for all those claiming under Tenant, any and all rights now or hereafter existing to redeem by order or 
judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises after any termination of this Lease.

19.2.1  Terminate  this  Lease  (pursuant  to  Section  1951.2  of  the  California  Civil  Code),  in  which  event  Tenant  shall,  upon  written  notice, 
immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for 
possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying 
the  Premises  or  any  part  thereof,  without  being  liable  for  prosecution  or  any  claim  or  damages  therefor;  and  Landlord  may  recover  from  Tenant  the 
following:

(i) The worth at the time of award of the unpaid rent which has been earned at the time of such termination; plus

-45-

 
until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

(ii) The worth at the time of award of the amount by which the unpaid rent which would have been earned after termination 

of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

(iii) The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease Term after the time 

(iv)  Any  other  amount  necessary  to  compensate  Landlord  for  all  the  detriment  proximately  caused  by  Tenant’s  failure  to 
perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including but 
not limited to, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or any portion thereof for a new 
tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant (“Costs of Reletting”); notwithstanding 
the above, if Landlord relets the Premises for a term (the “Relet Term”) that extends past the originally scheduled Lease Expiration Date, the 
Costs of Reletting which may be included in Landlord’s damages shall be limited to a prorated portion of the Costs of Reletting, based on the 
percentage  that  the  length  of  the  originally  scheduled  Lease  Term  remaining  on  the  date  Landlord  terminates  this  Lease  or  Tenant’s  right  to 
possession  bears  to  the  length  of  the  Relet  Term.  For  example,  if  there  are  two  (2)  years  left  on  the  Lease  Term  at  the  time  that  Landlord 
terminates possession and, prior to the expiration of the two (2) year period, Landlord enters into a lease with a new tenant with a Relet Term of 
ten (10) years, then only twenty percent (20%) of the Costs of Reletting shall be included when determining Landlord’s damages; and

time by applicable law.

(v) At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to 

The term “rent” as used in this Section 19.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant 
to  the  terms  of  this  Lease,  whether  to  Landlord  or  to  others.  As  used  in  Sections 19.2.1(i)  and  (ii),  above,  the  “worth  at  the  time  of  award”  shall  be 
computed by allowing interest at the rate set forth in Article 25 of this Lease, but in no case greater than the maximum amount of such interest permitted by 
law. As used in Section 19.2.1(iii) above, the “worth at the time of award”  shall  be  computed  by  discounting  such  amount  at  the  discount  rate  of  the 
Federal Reserve Bank of San Francisco at the time of award plus one percent (1%).

19.2.2  Landlord  shall  have  the  remedy  described  in  California  Civil  Code  Section  1951.4  (lessor  may  continue  lease  in  effect  after 
lessee’s  breach  and  abandonment  and  recover  rent  as  it  becomes  due,  if  lessee  has  the  right  to  sublet  or  assign,  subject  only  to  reasonable  limitations). 
Accordingly, if Landlord does not elect to terminate this Lease on account of any default by Tenant, Landlord may, from time to time, without terminating 
this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due.

19.2.3  Landlord  shall  at  all  times  have  the  rights  and  remedies  (which  shall  be  cumulative  with  each  other  and  cumulative  and  in 
addition to those rights and remedies available under this Section 19.2, or any law or other provision of this Lease), without prior demand or notice except 
as  required  by  Applicable  Law,  to  seek  any  declaratory,  injunctive  or  other  equitable  relief,  and  specifically  enforce  this  Lease,  or  restrain  or  enjoin  a 
violation or breach of any provision hereof. The provisions of this Section 19.2.6 are not dependent upon the occurrence of a default.

19.2.4 Any obligation imposed by law upon Landlord to relet the Premises after any termination of the Lease shall be subject to the 
reasonable requirements of Landlord to lease to high quality tenants on such terms as Landlord may from time to time deem appropriate and to develop the 
Building  in  a  harmonious  manner  with  an  appropriate  mix  of  uses,  tenants,  floor  areas  and  terms  of  tenancies,  and  the  like,  and  Landlord  shall  not  be 
obligated to relet the Premises to any party to whom Landlord or its affiliate may desire to lease other available space in the Building.

19.2.5 Nothing herein shall limit or prejudice the right of Landlord to prove and obtain in a proceeding for bankruptcy, insolvency, 
arrangement or reorganization, by reason of the termination, an amount equal to the maximum allowed by a statute of law in effect at the time when, and 
governing the proceedings in which, the 

-46-

 
damages are to be proved, whether or not the amount is greater to, equal to, or less than the amount of the loss or damage which Landlord has suffered.

19.3 Subleases of Tenant. Whether or not Landlord elects to terminate this Lease on account of any events of default by Tenant, as set forth in 
this Article 19,  Landlord  shall  have  the  right  to  terminate  any  and  all  subleases,  licenses,  concessions  or  other  consensual  arrangements  for  possession 
entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions 
or arrangements. In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant 
shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

19.4 Efforts to Relet. No re-entry or repossession, repairs, maintenance, changes, alterations and additions, reletting, appointment of a receiver 
to protect Landlord’s interests hereunder, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease 
or Tenant’s right to possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s 
obligations hereunder, unless express written notice of such intention is sent by Landlord to Tenant. Tenant hereby irrevocably waives any right otherwise 
available under any law to redeem or reinstate this Lease.

19.5 Landlord Default.

19.5.1 General. Notwithstanding anything to the contrary set forth in this Lease, Landlord shall not be in default in the performance of 
any obligation required to be performed by Landlord pursuant to this Lease unless Landlord fails to perform such obligation within thirty (30) days after 
the receipt of notice from Tenant specifying in detail Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that 
more than thirty (30) days are required for its performance, then Landlord shall not be in default under this Lease if it shall commence such performance 
within such thirty (30) day period and thereafter diligently pursue the same to completion. Upon any such default by Landlord under this Lease, Tenant 
may, except as otherwise specifically provided in this Lease to the contrary, exercise any of its rights provided at law or in equity.

20. COVENANT OF QUIET ENJOYMENT

Landlord  covenants  that  Tenant,  on  paying  the  Rent,  charges  for  services  and  other  payments  herein  reserved  and  on  keeping,  observing  and 
performing  all  the  other  terms,  covenants,  conditions,  provisions  and  agreements  herein  contained  on  the  part  of  Tenant  to  be  kept,  observed  and 
performed, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions 
and  agreements  hereof  without  interference  by  any  persons  lawfully  claiming  by  or  through  Landlord.  The  foregoing  covenant  is  in  lieu  of  any  other 
covenant express or implied.

21. SECURITY DEPOSIT

21.1 Delivery of Letter of Credit. Concurrently  with  Tenant’s  execution  of  this  Lease,  Tenant  shall  deposit  with  Landlord  an  unconditional, 
clean,  irrevocable  negotiable  letter  of  credit  (the  “L/C  Security”)  in  the  amount  set  forth  in  Section  9  of  the  Summary  as  security  for  the  faithful 
performance by Tenant of all of its obligations under this Lease as follows:

(a) Tenant shall provide Landlord and maintain in full force and effect throughout the Term and until the date that is ninety 
(90) days after the Lease Expiration Date, an evergreen letter of credit substantially in the form of Exhibit 21.1 issued by an issuer reasonably satisfactory 
to Landlord, in the amount set forth in Section 9 of the Summary. Silicon Valley Bank is hereby approved as an issuer of the L/C Security. If at any time 
during the Term (i) the financial condition of such issuer is reduced below a long term issuer credit rating from Standard and Poor’s Professional Rating 
Service  of  BBB+  or  a  comparable  rating  from  Moody’s  Professional  Rating  Service  or  Landlord  determines  in  its  sole  reasonable  discretion  that  the 
financial condition of issuer has changed in any materially adverse way from the financial condition of such issuer as of the date of execution of this Lease 
(any  of  the  foregoing,  a  “Bank  Credit  Threat”)  including,  without  limitation,  if  such  issuer  is  declared  insolvent  or  is  placed  into  receivership  or 
conservatorship by the Federal Deposit Insurance Corporation, or any successor or similar entity, if a trustee, receiver or liquidator is appointed for such 
issuer,  if  the  credit  rating  of  the  long-term  debt  of  the  issuer  of  the  letter  of  credit  (according  to  Moody’s,  Standard  &  Poor’s  or  similar  national  rating 
agency reasonably identified 

-47-

 
by Landlord) is downgraded to a grade below investment grade, if the issuer enters into any supervisory agreement with any governmental authority or fails 
to meet any capital requirements imposed by applicable law, Landlord may require the L/C Security to be replaced by an L/C Security issued by a different 
issuer, in which event Tenant shall, within fifteen (15) business days after written notice from Landlord, deliver to Landlord a replacement L/C Security 
issued by a commercial bank or savings and loan association acceptable to Landlord in its sole reasonable discretion and that meets all other requirements 
of this Article. If Tenant has actual notice, or Landlord notifies Tenant at any time, that any issuer of the L/C Security has become insolvent or placed into 
FDIC receivership, then Tenant shall promptly deliver to Landlord (without the requirement of further notice from Landlord) substitute L/C Security issued 
by  a  commercial  bank  or  savings  and  loan  association  acceptable  to  Landlord  in  its  reasonable  discretion  and  that  meets  all  other  requirements  of  this 
Article. As used herein with respect to the issuer of the L/C Security, “insolvent” shall mean the determination of insolvency as made by such issuer’s 
primary bank regulator (i.e., the state bank supervisor for state-chartered banks; the OCC or OTS, respectively, for federally chartered banks or thrifts; or 
the Federal Reserve for its member banks).

(b) Landlord may draw upon the L/C Security, and hold and apply the proceeds for the payment of any Rent or any other 
sum in default, or to compensate Landlord for any other loss or damage that Landlord may suffer by reason of Tenant’s default, if: (i) a default beyond 
applicable notice and cure periods exists (or would have existed with the giving of notice and passage of applicable cure periods, but only if transmittal of a 
default notice is stayed or barred by applicable bankruptcy or other similar law); (ii) as of the date sixty (60) days before any L/C Security expires Tenant 
has not delivered to Landlord an amendment or replacement for such L/C Security, reasonably satisfactory to Landlord, extending the expiry date to the 
date  that  is  ninety  (90)  days  after  the  then-current  Lease  Expiration  Date;  (iii)  Tenant  fails  to  pay  any  bank  charges  for  Landlord’s  transfer  of  the  L/C 
Security when due; (iv) the issuer of the L/C Security ceases, or announces that it will cease, to maintain an office in the city where Landlord may present 
drafts under the L/C Security (and fails to permit drawing upon the L/C Security by overnight courier or facsimile); (v) Tenant has filed a voluntary petition 
under the U.S. Bankruptcy Code or any state bankruptcy code (collectively, the “Bankruptcy Code”); or (vi) a Bank Credit Threat or Receivership (as 
such Term is defined in Section below) has occurred and Tenant has failed to comply with the requirements of either Section above or below, as applicable. 
This  Section  does  not  limit  any  other  provisions  of  this  Lease  allowing  Landlord  to  draw  the  L/C  Security  under  specified  circumstances.  The  use, 
application  or  retention  of  the  L/C  Security,  or  any  portion  thereof,  by  Landlord  shall  not  prevent  Landlord  from  exercising  any  other  right  or  remedy 
provided by this Lease or by any Applicable Law, it being intended that Landlord shall not first be required to proceed against the L/C Security and shall 
not  operate  as  a  limitation  on  any  recovery  to  which  Landlord  may  otherwise  be  entitled.  Tenant  agrees  not  to  interfere  in  any  way  with  payment  to 
Landlord of the proceeds of the L/C Security, either prior to or following a “draw” by Landlord of any portion of the L/C Security, regardless of whether 
any dispute exists between Tenant and Landlord as to Landlord’s right to draw upon the L/C Security. No condition or term of this Lease shall be deemed to 
render the L/C Security conditional to justify the issuer of the L/C Security in failing to honor a drawing upon such L/C Security in a timely manner. Tenant 
agrees and acknowledges that (i) the L/C Security constitutes a separate and independent contract between Landlord and the issuer, (ii) Tenant is not a third 
party beneficiary of such contract, (iii) Tenant has no property interest whatsoever in the L/C Security or the proceeds thereof, and (iv) in the event Tenant 
becomes a debtor under any chapter of the Bankruptcy Code, neither Tenant, any trustee, nor Tenant’s bankruptcy estate shall have any right to restrict or 
limit Landlord’s claim and/or rights to the L/C Security and/or the proceeds thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or 
otherwise.  In  the  event  of  any  such  draw  upon  the  L/C  Security,  Tenant  shall  within  fifteen  (15)  business  days  thereafter  provide  Landlord  with  a 
replacement letter of credit, or amendment to the existing letter of credit increasing the amount of such letter of credit, in the amount of L/C Security, and in 
the form, required hereunder, and Tenant’s failure to do so shall be a material breach of this Lease.

(c)  If  Landlord  transfers  its  interest  in  the  Premises,  then  Landlord  shall  transfer  the  L/C  Security  to  the  transferee  of  its 
interest and notify Tenant of such transfer, and Tenant shall at Tenant’s expense, within fifteen (15) business days after receiving a request from Landlord, 
deliver (and, if the issuer requires, Landlord shall consent to) an amendment to the L/C Security naming Landlord’s grantee as substitute beneficiary. If the 
required  Security  Deposit  changes  while  L/C  Security  is  in  force,  then  Tenant  shall  deliver  (and,  if  the  issuer  requires,  Landlord  shall  consent  to)  a 
corresponding amendment to the L/C Security.

held by Landlord as security for the faithful performance by Tenant of all of the terms, 

(d) If and to the extent Landlord is holding the proceeds of the L/C Security in cash from time to time, such cash shall be 

-48-

 
covenants and conditions of this Lease to be kept and performed by Tenant during the period commencing on the Execution Date and ending upon the 
expiration  or  termination  of  Tenant’s  obligations  under  this  Lease.  If  Tenant  defaults  (beyond  applicable  notice  and  cure  periods)  with  respect  to  any 
provision of this Lease, including any provision relating to the payment of Rent, then Landlord may (but shall not be required to) use, apply or retain all or 
any part of the Security Deposit for the payment of any Rent or any other sum in default, or to compensate Landlord for any other loss or damage that 
Landlord may suffer by reason of Tenant’s default as provided in this Lease. The provisions of this Article shall survive the expiration or earlier termination 
of  this  Lease.  In  the  event  of  bankruptcy  or  other  debtor-creditor  proceedings  against  Tenant,  any  cash  security  then  being  held  by  Landlord  shall  be 
deemed to be applied first to the payment of Rent and other charges due Landlord for all periods prior to the filing of such proceedings. Landlord shall 
deliver or credit to any purchaser of Landlord’s interest in the Premises the funds then held hereunder by Landlord, and thereupon (and upon confirmation 
by the transferee of such funds, whether expressly or by written assumption of this Lease, generally) Landlord shall be discharged from any further liability 
with respect to such funds. This provision shall also apply to any subsequent transfers. If Tenant shall fully and faithfully perform every provision of this 
Lease to be performed by it, then the cash security, if any, or any balance thereof, shall be returned to Tenant (or, at Landlord’s option, to the last assignee 
of Tenant’s interest hereunder) within ninety (90) days after the expiration or earlier termination of this Lease. If and to the extent the security held by 
Landlord hereunder shall be in cash, Landlord shall hold such cash in an account at a banking organization selected by Landlord; provided, however, that 
Landlord shall not be required to maintain a separate account for the cash security but may intermingle it with other funds of Landlord. Landlord shall be 
entitled to all interest and/or dividends, if any, accruing on such cash security.

21.2 Letter  of  Credit  not  a  Security  Deposit.  Landlord  and  Tenant  acknowledge  and  agree  that  in  no  event  or  circumstance  shall  the  L/C 
Security, the “security deposit” (as that term is defined in Section 21.3 below), if applicable, or any renewal thereof or any proceeds thereof, be (i) deemed 
to be or treated as a “security deposit” within the meaning of California Civil Code Section 1950.7, (ii) subject to the terms of such Section 1950.7, or (iii) 
intended to serve as a “security deposit” within the meaning of such Section 1950.7. The parties hereto (A) recite that the L/C Security and the Security 
Deposit (if applicable) are not intended to serve as a security deposit and such Section 1950.7 and any and all other laws, rules and regulations applicable to 
security deposits in the commercial context (“Security Deposit Laws”) shall have no applicability or relevancy thereto and (B) waive any and all rights, 
duties and obligations either party may now or, in the future, will have relating to or arising from the Security Deposit Laws.

21.3 Proceeds of Draw. In the event Landlord draws down on the L/C Security pursuant to Section 21.1(b)(ii) and (vi) above, the proceeds of 
the L/C Security may be held by Landlord and applied by Landlord against any Rent payable by Tenant under this Lease that is not paid when due (subject 
to applicable notice and cure periods) and/or to pay for all losses and damages that Landlord has suffered or that Landlord reasonably estimates that it will 
suffer  as  a  result  of  any  breach  or  default  by  Tenant  under  this  Lease.  Any  unused  proceeds  shall  constitute  the  property  of  Landlord  and  need  not  be 
segregated from Landlord’s other assets. Tenant hereby (i) agrees that (A) Tenant has no property interest whatsoever in the proceeds from any such draw, 
and (B) such proceeds shall not be deemed to be or treated as a “security deposit” under the Security Deposit Laws, and (ii) waives all rights, duties and 
obligations either party may now or, in the future, will have relating to or arising from the Security Deposit Laws. Landlord agrees that the amount of any 
proceeds of the L-C received by Landlord, and not (a) applied against any Rent payable by Tenant under this Lease that was not paid when due or (b) used 
to pay for any losses and/or damages suffered by Landlord (or reasonably estimated by Landlord that it will suffer) as a result of any breach or default by 
Tenant under this Lease (the “Unused L/C Proceeds”), shall be paid by Landlord to Tenant (x) upon receipt by Landlord of a replacement L/C Security in 
the required amount, which replacement L/C Security shall comply in all respects with the requirements of this Article 21, and (y) immediately after the LC 
Expiration Date; provided, however, that if prior to the LC Expiration Date a voluntary petition is filed by Tenant, or an involuntary petition is filed against 
Tenant by any of Tenant’s creditors, under the Bankruptcy Code, then Landlord shall not be obligated to make such payment in the amount of the Unused 
L/C Proceeds until either all preference issues relating to payments under this Lease have been resolved in such bankruptcy or reorganization case or such 
bankruptcy or reorganization case has been dismissed.

21.4  Issuing  Bank  Placed  Into  Receivership.  In  the  event  the  issuer  is  placed  into  receivership  or  conservatorship  (any  such  event,  a 
“Receivership”)  by  the  Federal  Deposit  Insurance  Corporation  or  any  successor  or  similar  entity  (the  “FDIC”),  then,  effective  as  of  the  date  such 
Receivership  occurs,  the  L/C  Security  shall  be  deemed  to  not  meet  the  requirements  of  this  Article  21,  and,  within  ten  (10)  business  days  following 
Landlord’s notice to Tenant of such Receivership, Tenant shall replace the L/C Security with a substitute L/C Security from a different 

-49-

 
issuer reasonably acceptable to Landlord and that complies in all respects with the requirements of this Article 21. If Landlord draws upon the L/C Security 
due to solely Tenant’s failure to provide a substitute L/C Security due to a Bank Credit Threat or Receivership, such failure shall not constitute a default 
hereunder  and  Tenant  shall  thereafter  have  the  right  to  provide  a  substitute  L/C  Security  that  satisfies  the  requirements  of  this  Lease,  in  which  case, 
Landlord shall concurrently refund the proceeds of the draw or the Security Deposit, as applicable. In connection with the foregoing, Tenant shall not be 
entitled to any interest on the Security Deposit, and Landlord’s use of the proceeds of the L/C Security shall be subject to the terms and conditions of the 
Lease pertaining to Landlord’s right to use the proceeds of the L/C Security.

21.5 Reduction of L-C Amount. Provided that Tenant has not previously been in default beyond all applicable notice and cure periods within 
the  twenty-four  (24)  months  immediately  prior  to  the  effective  date  of  the  reduction  request  and  further  if  Tenant  is  not  in  default  at  the  time  of  such 
request,  upon  written  request  by  Tenant  given  at  any  time  after  the  first  day  of  the  forty-ninth  (49th)  full  calendar  month  of  the  Lease  Term,  the  L/C 
Security amount shall be reduced to $3,805,770.64. The reduction of the L/C Security amount shall be effectuated by Tenant’s delivery to Landlord of a 
certificate of amendment to the existing L/C Security, conforming in all respects to the requirements of this Article 21, in the amount of the applicable 
reduced  L/C  Security  amount.  If  Tenant  is  allowed  to  reduce  the  L/C  Security  amount  pursuant  to  the  terms  of  this  Section 21.5,  then  Landlord  shall 
reasonably cooperate with Tenant in order to effectuate such reduction.

22. INTENTIONALLY OMITTED

23. SIGNS

23.1 Signage.  Tenant  shall  not  install  any  signage  (including,  without  limitation,  any  signs  identifying  Tenant’s  name  or  advertising  Tenant’s 
merchandise or otherwise) in or about the Premises that is visible from the exterior of the Premises or in any other part of the Project except as expressly 
permitted in this Section 23.1 or Section 23.2 below. Subject to Landlord’s prior written approval, in its reasonable discretion, and provided all signs are in 
keeping with the quality, design and style of the Building and Project, Tenant, at its sole cost and expense, may install one sign identifying Tenant at the 
entry  to  the  Premises  on  each  floor  of  the  Premises,  which  identification  signage  shall  be  consistent  with  building  standard  signage  as  determined  by 
Landlord. All permitted signs shall be maintained by Tenant at its expense in a first-class and safe condition and appearance. Upon the expiration or earlier 
termination of this Lease, Tenant shall remove all of its signs at Tenant’s sole cost and expense. Tenant shall repair any damage to the Premises or Project, 
inside  or  outside,  resulting  from  the  erection,  maintenance  or  removal  of  any  signs.  Tenant’s  signage  must  also  comply  with  all  Applicable  Laws.  All 
Building signage shall be subject to the existing rights of other tenants in the Building and any declaration of covenants for the Project.

23.2 Full Floors. Subject to Landlord’s prior written approval, in its reasonable discretion, and provided all signs are in keeping with the quality, 
design  and  style  of  the  Buildings  and  Project,  (a)  to  the  extent  that  the  Premises  includes  any  full  floor(s)  of  any  Building,  Tenant,  at  its  sole  cost  and 
expense, may install identification signage anywhere on such floor(s), and (b) to the extent that the Premises includes any partial floor(s) of any Building, 
Tenant, at its sole cost and expense, may install Building standard identification signage in the elevator lobby and at the entrance to the Premises on such 
floor(s).  Subject  to  Landlord’s  consent,  Tenant  will  be  entitled  to  Building-standard  identification  signage  in  the  elevator  lobby  or  lobbies  serving  the 
Premises as well as in any ground floor Building lobby directory. Tenant shall be solely responsible, at Tenant’s sole cost and expense, for the installation 
and removal of such signage. Tenant’s signage in any ground floor Building Lobby will be limited 9” x 18” and will be the monochromatic/black and white 
lettering or logo for Tenant. Additionally, with the prior written consent of Landlord, and in compliance with the provisions of this Lease, Tenant may, at 
Tenant’s  sole  cost  and  expense,  install  customized  branding  signage  in  the  elevator  lobby  on  the  eighth  (8th),  ninth  (9th),  tenth  (10th),  eleventh  (11th) 
and/or twelfth (12th) floor of the North Tower, provided that Tenant will be obligated to remove any such signage and repair any damage caused by the 
installation and/or removal of such signage at the expiration or sooner termination of this Lease.

23.3 Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names or advertisements which are installed and are visible from 
the exterior of the Premises or in any other part of the Project and that have not been separately approved by Landlord may be removed without notice by 
Landlord at the sole expense of Tenant. Tenant may not install any signs on the exterior or roof of the Project or the Common Areas. Any signs, displays, 
window coverings, window lettering, or blinds (even if the same are located behind the Landlord-approved window coverings for the Building), or other 
items or Alterations visible from the exterior of the Premises or Building, shall 

-50-

 
be subject to the prior approval of Landlord, in its sole discretion. Tenant shall not place or install any projections, antennae, aerials, or similar devices 
inside or outside of the Building, without the prior written approval of Landlord, subject to Tenant’s rights pursuant to Section 23.2 above.

23.4 Exterior Building Signage. During the Lease Term for so long as Tenant or a Permitted Assignee occupies at least seventy percent (70%) 
of the Premises, Landlord shall not allow any Competitor of Tenant to have exterior Building signage on the North Tower above eyebrow signage height. 
As  used  herein,  “Competitor  of  Tenant”  means  (i)  a  life  science  company  that  primarily  focuses  on  an  immunological  approach  to  developing 
pharmaceuticals for treating and preventing serious infectious diseases and (ii) is identified by Tenant as a competitor of Tenant on the list of competitors 
delivered by Tenant to Landlord from time to time and then in effect as between Landlord and Tenant as contemplated by this Section 23.4. At any time 
following  the  execution  and  delivery  of  this  Lease  by  Landlord  and  Tenant,  Tenant  may  deliver  to  Landlord,  in  writing,  an  initial  list  of  competitors 
containing no more than ten (10) companies, and such list will be valid (i.e., in full force and effect) for the ensuing twenty-four (24) months (which list of 
competitors,  as  updated  from  time  to  time  in  accordance  with  this  Section 23.4,  may  be  referred  to  as  the  “Competitor List”). Thereafter, Tenant may 
update the initial Competitor List and any subsequently updated Competitor List every twenty-our (24) months during the Lease Term. If Tenant either fails 
to deliver to Landlord (i) an initial Competitor List, (ii) an update to the initial Competitor List after twenty-four (24) months have elapsed, or (ii) an update 
of the then most recently updated Competitor List after twenty-four (24) months have elapsed, then Landlord may give to Tenant written notice requesting 
Tenant deliver to Landlord either the initial Competitor List or an updated Competitor List, as applicable, and Tenant shall thereafter have ten (10) business 
days to deliver to Landlord a Competitor List identifying no more than ten (10) companies, and such Competitors List shall be valid for the ensuing twenty-
four (24) months. If Tenant fails to deliver to Landlord an initial Competitor List, Landlord may give to Tenant a second written notice reminding Tenant of 
the  need  to  provide  an  initial  Competitor  List  and  if  Tenant  fails  to  provide  such  an  initial  Competitor  List,  then  Landlord  shall  not  be  subject  to  any 
prohibition  relating  to  exterior  Building  signage  on  the  North  Tower  for  the  ensuing  twenty-four  (24)  months;  if  Tenant  fails  to  deliver  to  Landlord  an 
updated Competitor List within the time period for Tenant’s response, then the previous Competitor List will continue to remain valid for an additional, 
ensuing twenty-four (24) months. Notwithstanding anything to the contrary contained in this Section 23.4, Landlord shall (i) be entitled to grant any retail 
tenants  the  rights  to  install  their  standard  building  sign  package,  including  eyebrow  signage,  blade  signage  and  store  front  signage,  on  or  about  their 
premises, (ii) be entitled to grant any tenants monument signage rights, and (iii) have no responsibility or liability for any exterior Building signage in any 
way attributable to Dropbox.

24. COMPLIANCE WITH LAW

24.1 By Tenant. Tenant shall not do anything or suffer anything to be done by any Tenant Party in or about the Premises or the Project which 
will in any way conflict with any law, statute, ordinance or other federal, state or local governmental rule, regulation or requirement now in force or which 
may  hereafter  be  enacted  or  promulgated  (collectively,  “Applicable Laws”).  At  its  sole  cost  and  expense,  Tenant  shall  promptly  comply  with  all  such 
Applicable Laws which relate to (i) Tenant’s use of the Premises, (ii) any Alterations made by Tenant to the Premises or the Tenant Improvements, or (iii) 
the Base Building, but as to the Base Building, only to the extent such obligations are triggered by Alterations or Tenant Improvements to the extent such 
Alterations are not normal and customary business office improvements in Comparable Buildings, or triggered by the Tenant Improvements to the extent 
such Tenant Improvements ae not normal and customary business office improvements, or triggered by Tenant’s particular use of the Premises and Project 
as opposed to customary business office use. Tenant shall not, however, be responsible for the cost of complying with Applicable Laws to the extent that 
any such compliance is required as a result of the Base Building failing to comply with Applicable Laws in effect as of date the Building was substantially 
completed (i.e., 2018). Notwithstanding the foregoing terms of this Article 24 to the contrary, Tenant may defer such compliance with Applicable Laws 
while Tenant contests, in a court of proper jurisdiction, in good faith, the applicability of such Applicable Laws to the Premises or Tenant’s specific use or 
occupancy  of  the  Premises;  provided,  however,  Tenant  may  only  defer  such  compliance  if  such  deferral  shall  not  (a)  prohibit  Tenant  from  obtaining  or 
maintaining a certificate of occupancy for the Premises, (b) prohibit Landlord from obtaining or maintaining a certificate of occupancy for the Building or 
any  portion  thereof,  (c)  unreasonably  and  materially  affect  the  safety  of  the  employees  and/or  invitees  of  Landlord  or  of  any  tenant  in  the  Building 
(including Tenant), (d) create a significant health hazard for the employees and/or invitees of Landlord or of any tenant in the Building (including Tenant), 
(e) otherwise materially and adversely affect Tenant’s use of or access to the Buildings or the Premises, or (f) impose material obligations, liability, fines, or 
penalties upon Landlord or any other tenant of the Building, or would materially and 

-51-

 
adversely  affect  the  use  of  or  access  to  the  Building  by  Landlord  or  other  tenants  or  invitees  of  the  Building.  The  judgment  of  any  court  of  competent 
jurisdiction  or  the  admission  of  Tenant  in  any  judicial  action,  regardless  of  whether  Landlord  is  a  party  thereto,  that  Tenant  has  violated  any  of  said 
governmental measures, shall be conclusive of that fact as between Landlord and Tenant. Landlord shall comply with all Applicable Laws relating to the 
Common Areas of the Building, provided that compliance with such Applicable Laws is not the responsibility of Tenant under this Lease, and provided 
further that Landlord’s failure to comply therewith would prohibit Tenant from obtaining or maintaining a certificate of occupancy for the Premises, or 
would unreasonably and materially affect the safety of Tenant’s employees or create a significant health hazard for Tenant’s employees, or would otherwise 
materially  and  adversely  affect  Tenant’s  use  of  or  access  to  the  Premises.  Landlord  shall  be  permitted  to  include  in  Operating  Expenses  any  costs  or 
expenses incurred by Landlord under this Article 24 to the extent not prohibited by the terms of Section 4.2.4 above.

24.2 By Landlord. Except as provided in the Tenant Work Letter, to the extent required in order for Tenant to obtain a Certificate of Occupancy 
to legally occupy the Premises for normal and customary office use, assuming normal and customary office occupancy density, or to the extent required in 
order for Tenant to pull a construction permit or to otherwise comply with the requirements of the applicable permitting authority, Landlord (rather than 
Tenant) shall comply with all Applicable Laws relating to the Base Building and Common Areas, except to the extent such compliance is triggered by (a) 
Tenant’s particular use of the Premises for other than normal and customary business office use or (b) Tenant’s construction of Alterations or Improvements 
in the Premises that are not normal and customary office improvements for Comparable Buildings in which case compliance with such Applicable Laws 
shall  be  the  responsibility  of  Tenant  under  this  Lease.  Landlord  shall  be  permitted  to  include  in  Operating  Expenses  any  costs  or  expenses  incurred  by 
Landlord under this Article 24 to the extent not prohibited by the terms of Article 4 above.

24.3 Certified Access Specialist. For purposes of Section 1938 of the California Civil Code, Landlord hereby discloses to Tenant, and Tenant 
hereby acknowledges, that neither the Premises, the Building nor the Common Areas have undergone inspection by a Certified Access Specialist (CASp). 
Pursuant to California Civil Code Section 1938, Tenant is hereby notified as follows: “A  Certified  Access  Specialist  (CASp)  can  inspect  the  subject 
premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state 
law. Although state law does not require a CASp inspection of the subject premises, the commercial property owner or lessor may not prohibit the 
lessee  or  tenant  from  obtaining  a  CASp  inspection  of  the  subject  premises  for  the  occupancy  or  potential  occupancy  of  the  lessee  or  tenant,  if 
requested  by  the  lessee  or  tenant.  The  parties  shall  mutually  agree  on  the  arrangements  for  the  time  and  manner  of  any  CASp  inspection,  the 
payment of the fee for the CASp inspection and the cost of making any repairs necessary to correct violations of construction-related accessibility 
standards within the premises.” If Tenant requests to perform a CASp inspection of the Premises, Tenant shall, at its cost, retain a CASp approved by 
Landlord (provided that Landlord may designate the CASp, at Landlord’s option) to perform the inspection of the Premises at a time agreed upon by the 
parties. Tenant shall provide Landlord with a copy of any report or certificate issued by the CASp (the “CASp Report”). Landlord and Tenant agree that 
any modifications necessary to correct violations of construction-related accessibility standards identified in the CASp Report shall be the responsibility of 
Tenant. Tenant agrees to keep the information in the CASp Report confidential except as necessary for the Tenant to complete such modifications.

24.4 Underlying Documents.  Tenant  shall  comply  with  all  easements,  licenses,  operating  agreements,  declarations,  restrictive  covenants,  or 
instruments  pertaining  to  the  sharing  of  costs  by  Landlord  with  respect  to  the  Project,  including,  without  limitation,  any  covenants,  conditions  and 
restrictions affecting the Project, and reciprocal easement agreements affecting the Project, any parking licenses, and any agreements with transit agencies 
affecting  the  Project  (collectively,  “Underlying  Documents”),  including,  without  limitation,  (i)  that  certain  Amended  and  Restated  Declaration  and 
Agreement of Covenants, Conditions and Restrictions for the UCSF Mission Bay Campus recorded July 19, 1999 in the Official Records as Instrument No. 
99¬G622193-00, (ii) that certain Master Declaration of Covenants, Conditions, Restrictions and Reservation of Easements for Mission Bay Commercial, 
recorded  January  16,  2001  in  the  Official  Records  as  Instrument  No.  2001-G889923-00,  (iii)  that  certain  Mission  Bay  South  Owner  Participation 
Agreement  between  the  Redevelopment  Agency  of  the  City  and  County  of  San  Francisco  (the  “Redevelopment  Agency”)  and  Catellus  Development 
Corporation (“CDC”) recorded December 3, 1998 in the Official Records as Instrument No. 98-G477258-00 (as amended, the “OPA”), (iv) that certain 
Redevelopment Plan for the Mission Bay South Redevelopment Project recorded November 18, 1998 in the Official Records as Instrument 

-52-

 
No. 98-G470337-00 (the “Redevelopment Plan”), and (v) that certain Mission Bay South Redevelopment Plan Area Declaration of Restrictions recorded 
December 3, 1998 in the Official Records as Instrument No. 98-G477250-00. Additionally, Tenant acknowledges that the Project may be subject to future 
Underlying  Documents,  which  Landlord,  in  Landlord’s  discretion,  deems  reasonably  necessary  or  desirable,  and  Tenant  agrees  that  this  Lease  shall  be 
subject and subordinate to such Underlying Documents and Tenant shall promptly execute and acknowledge, within fifteen (15) business days of a request 
by Landlord, a “Recognition of Covenants, Conditions, and Restrictions,” in a form substantially similar to that attached hereto as Exhibit 24.4 agreeing to 
and acknowledging the applicable Underlying Document.

25. LATE CHARGES

If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord’s designee within five (5) business 
days after the date due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any reasonable attorneys’ 
fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder. Notwithstanding the foregoing, Landlord 
shall not charge Tenant a late charge for the first (1st) late payment in any twelve (12) month period unless Tenant fails to timely pay such amount within 
five  (5)  business  days  following  notice  from  Landlord  that  such  amount  is  past  due.  The  late  charge  shall  be  deemed  Additional  Rent  and  the  right  to 
require it shall be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as 
limiting Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing hereunder which are not paid 
within ten (10) days after the date they are due shall bear interest from the date when due until paid at a rate per annum equal to the lesser of (i) the annual 
“Bank Prime Loan” rate cited in the Federal Reserve Statistical Release Publication H.15, published on the first Tuesday of each calendar month (or such 
other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published) plus four (4) percentage points, and (ii) the 
highest rate permitted by Applicable Law.

26. LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT

26.1 Landlord’s Cure.  All  covenants  and  agreements  to  be  kept  or  performed  by  Tenant  under  this  Lease  shall  be  performed  by  Tenant  at 
Tenant’s sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to 
perform any obligation under this Lease, and such failure shall continue in excess of the time allowed under Section 19.1.2 above, unless a specific time 
period  is  otherwise  stated  in  this  Lease,  Landlord  may,  but  shall  not  be  obligated  to,  make  any  such  payment  or  perform  any  such  act  on  Tenant’s  part 
without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder. Except as may be specifically 
provided to the contrary in this Lease, Tenant shall pay to Landlord, within five (5) days after delivery by Landlord to Tenant of statements therefor: (i) 
sums  equal  to  expenditures  reasonably  made  and  obligations  incurred  by  Landlord  in  connection  with  the  remedying  by  Landlord  of  Tenant’s  defaults 
pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses referred to in Article 10 of this Lease; and 
(iii) sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting 
to  enforce  any  rights  of  Landlord  under  this  Lease  or  pursuant  to  law,  including,  without  limitation,  all  reasonable  legal  fees  and  other  amounts  so 
expended. Tenant’s obligations under this Section 26.1 shall survive the expiration or sooner termination of the Lease Term.

27. PROJECT CONTROL BY LANDLORD; ENTRY BY LANDLORD

27.1 Project Control. Landlord reserves full control over the Building and the Project to the extent not inconsistent with Tenant’s enjoyment of 
the Premises as provided by this Lease. This reservation includes Landlord’s right to subdivide the Project; convert the Building or Project to condominium 
units; change the size of the Project by selling all or a portion of the Project or adding real property and any improvements thereon to the Project; grant 
assessments  and  licenses  to  third  parties;  maintain  or  establish  ownership  of  the  Building  separate  from  fee  title  to  the  Property;  make  additions  to  or 
reconstruct portions of the Building and the Project; install, use, maintain, repair, replace and relocate for service to the Premises and other parts of the 
Building or the Project pipes, ducts, conduits, wires and appurtenant fixtures, wherever located in the Premises, the Building or elsewhere at the Project; 
and alter or relocate any other Common Area or facility, including private drives, lobbies and entrances. Landlord’s right pursuant to this Section 27.1, 
including without limitation the rights to construct, maintain, relocate, alter, improve, or adjust the Building or the Project shall be subject to the condition 
that (i) the exercise of any of such rights shall 

-53-

 
not materially and adversely interfere with Tenant’s use of the Premises or materially decrease the number of Tenant’s parking spaces, (ii) Landlord shall 
provide reasonable prior notice to Tenant before exercising any such rights which may materially and adversely interfere with Tenant’s use of the Premises, 
provided that such use of the Premises is in accordance with the Permitted Use, and (iii) Landlord shall use reasonable efforts to minimize to the extent 
possible  any  interference  with  Tenant’s  business,  provided  that  such  business  is  in  accordance  with  the  Permitted  Use,  including,  when  reasonable, 
scheduling such work after business hours or on weekends. Possession of areas of the Premises necessary for utilities, services, safety and operation of the 
Building is reserved to Landlord. Notwithstanding the foregoing, Landlord shall provide Tenant reasonable prior notice of required access to the Premises 
for such activities.

27.2 Entry by Landlord. Landlord reserves the right at all reasonable times and upon not less than three (3) days’ prior notice to Tenant (except 
in the case of an emergency or with respect to regularly scheduled services) to enter the Premises to (i) inspect them; (ii) show the Premises to prospective 
purchasers,  or  to  current  or  prospective  mortgagees,  ground  or  underlying  lessors  or  insurers  or,  during  the  last  nine  (9)  months  of  the  Lease  Term,  to 
prospective tenants; (iii) post notices of non-responsibility (to the extent applicable pursuant to then Applicable Law); or (iv) alter, improve or repair the 
Premises or the Building, or for structural alterations, repairs or improvements to the Building or the Building’s systems and equipment.  Notwithstanding 
the foregoing, if Landlord desires to enter the Premises upon less than three (3) days’ notice, Tenant shall use good faith, diligent efforts to accommodate 
Landlord’s entry upon such shorter notice. Tenant shall additionally have the right to require that Landlord be accompanied by a representative of Tenant 
during any such entry as an escort for Landlord’s personnel so long as Tenant makes a representative available at commercially reasonable times; provided, 
however,  any  entry  into  the  BSL  3  laboratory  area  shall  be  restricted  to  persons  (i)  with  proper  training  as  to  Tenant’s  applicable  safety  and  security 
protocols, (ii) appropriate personal protective equipment as reasonably required by Tenant, and (iii) accompanied by a representative of Tenant as an escort 
for such persons (which representative Tenant shall make available at all commercially reasonable times). Provided that Landlord employs commercially 
reasonable efforts to minimize interference with the conduct of Tenant’s business in connection with entries into the Premises, Landlord may make any 
such entries without creating a default by Landlord and shall take such reasonable steps as required to accomplish the stated purposes. In making any such 
entry,  Landlord  shall  use  commercially  reasonable  efforts  to  follow,  and  cause  third  parties  making  entry  at  the  request  of  Landlord  to  follow,  Tenant’s 
safety and security protocols of which Landlord has prior notice. In an emergency, Landlord shall have the right to use any means that Landlord may deem 
proper to open the doors in and to the Premises. Landlord also shall have the right at any time, without the same constituting an actual or constructive 
eviction and without incurring any liability to Tenant therefor, to change the arrangement or location of entrances or passageways, doors and doorways, and 
corridors, elevators, stairs, toilets, or other public parts of the Building and to change the name, address, number or designation by which the Premises is 
commonly known, provided any such change does not (A) unreasonably reduce, interfere with or deprive Tenant of access to the Premises nor compromise 
the safety and security protocols applicable to the laboratory areas within the Premises, or (B) reduce the rentable area (except by a de minimis amount) of 
the Premises. Any entry into the Premises by Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or 
a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises and the Base Rent (and any other item of Rent) 
shall under no circumstances abate while said repairs, alterations, improvements, additions or restorations are being made, by reason of loss or interruption 
of business of Tenant, or otherwise. If Tenant shall not be present when for any reason entry into the Premises shall be necessary or permissible, Landlord 
or Landlord’s agents, representatives, contractors or employees may enter the same without rendering Landlord or such agents liable therefor if during such 
entry Landlord or Landlord’s agents shall accord reasonable care under the circumstances to Tenant’s Property, and without in any manner affecting this 
Lease. Tenant shall, at all times during the Term, be responsible for ensuring that Landlord has any and all keys, cards, codes or other means necessary to 
access the Premises.

28. TENANT PARKING

28.1 Parking Passes.  During  the  Lease  Term  Landlord  shall  provide  Tenant  with  parking  passes  for  use  by  standard  size  automobiles  in  an 
amount equal to the number of parking passes set forth in Section 11 of the Summary, which parking passes shall pertain to the Project parking facility 
facilities (the “Parking Facilities”). All such parking shall be on a first-come, first-serve basis in common with others entitled to use the same. Tenant’s 
continued right to use the parking passes is conditioned upon Tenant abiding by all rules and regulations which are prescribed from time to time for the 
orderly operation and use of the parking facility where the parking passes provide access (including 

-54-

 
any sticker or other identification system established by Landlord and the prohibition of vehicle repair and maintenance activities in the parking facilities), 
and Tenant shall cooperate in seeing that any Tenant Parties and Tenant visitors also comply with such rules and regulations. Tenant’s use of the parking 
passes for parking at the Project shall be at Tenant’s sole risk and Tenant acknowledges and agrees that Landlord shall have no liability whatsoever for 
damage to the vehicles of Tenant, its employees and/or visitors, or for other personal injury or property damage or theft relating to or connected with the 
parking  rights  granted  herein  or  any  of  Tenant’s,  its  employees’  and/or  visitors’  use  of  the  parking  facilities.  Landlord  shall  have  the  right  to  assign  its 
obligations under this Section 28 to an affiliate of Landlord or a third-party parking manager or operator, in which case Tenant shall make any payments 
due under this Section 28 directly to such other entity.

28.2 Parking Pass Rates. Tenant shall pay to Landlord for Parking Passes on a monthly basis the monthly parking rate charged by Landlord, 
which  monthly  rate  for  Parking  Passes  (the  “Parking Rate”)  shall  initially  be  equal  to,  and  during  the  Lease  Term  shall  not  be  less  than,  $345.00  per 
Parking Pass per month (the “Parking Rate Floor”). Subject to the Parking Rate Floor, the Parking Rate shall be adjusted annually to be consistent with 
the prevailing monthly parking rate for similar parking spaces then being charged by landlords in Mission Bay. In addition, Tenant shall be responsible for 
the full amount of any taxes imposed by any governmental authority in connection with the renting of such Parking Passes by Tenant for the use of the 
Parking Facilities by Tenant.

28.3 Use of Parking Passes. Tenant shall cooperate with Landlord to ensure that its employees comply with all reasonable rules and regulations 
which  are  prescribed  from  time  to  time  for  the  orderly  operation  and  use  of  the  Parking  Facilities,  including  any  sticker  or  other  identification  system 
established  by  Landlord.  Landlord  specifically  reserves  the  right  to  change  the  size,  configuration,  design,  layout  and  all  other  aspects  of  the  Parking 
Facilities at any time and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent 
under  this  Lease,  from  time  to  time,  temporarily  close-off  or  restrict  access  to  the  Parking  Facilities  for  purposes  of  permitting  or  facilitating  any  such 
construction, alteration or improvements; provided, however, that Landlord will use reasonable efforts to provide Tenant with reasonable advance notice of 
any such anticipated temporary close-off or restriction in access to the Parking Facilities. Landlord may delegate its responsibilities hereunder to a parking 
operator in which case such parking operator shall have all the rights of control attributed hereby to the Landlord. The Parking Passes rented by Tenant 
pursuant to this Article 28 are provided to Tenant solely for use by Tenant’s own personnel and such passes may not be transferred, assigned, subleased or 
otherwise alienated by Tenant, except in connection with a Transfer of the Premises pursuant to Article 14 of this Lease, without Landlord’s prior approval. 
Tenant may validate visitor parking by such method or methods as the Landlord may establish, at the validation rate from time to time generally applicable 
to visitor parking. Tenant’s use of the Parking Facilities are on a non-exclusive basis.

28.4  Electrical  Vehicle  Charging.  At  least  ten  (10)  electrical  vehicle  charging  stations  in  the  Parking  Facilities  shall  be  available  for  non-

exclusive use by Tenant on a first-come, first-served basis.

28.5 Public Parking Use. Landlord shall have the right to permit use (the “Public Parking Use”) of the Parking Facilities by the general public 
(or for any other use). Landlord may accommodate the Public Parking Use through valet parking, tandem or stack parking, or any other parking program 
using  parking  personnel  and/or  systems  and  equipment;  provided,  however,  in  connection  with  the  Public  Parking  Use,  Landlord  shall  cooperate  with 
Tenant to minimize interference with Tenant’s use of the Parking Facilities, which may include developing a system to partially or totally segregate the 
areas designated for Public Parking Use in the Parking Facilities from the areas designated for use (the “Project Parking Use”) by Tenant, other tenants or 
occupants  of  the  Project,  visitors  of  the  Project,  transient  parkers  of  the  Project,  and  Landlord  and  its  affiliates  and  service  providers  for  the  Project 
(collectively, the “Project Related Parkers”). To account for the shared use of the Parking Facilities for the Public Parking Use and Project Parking Use, 
Landlord and Tenant agree that any incremental increase in (i) parking and security personnel costs and (ii) costs for parking access control equipment, 
which is directly attributable to the Public Parking Use shall be excluded from Operating Expenses.

28.6 Storage Use. [***].

in connection herewith or with Landlord’s operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or the

29.14 Entire Agreement. It is understood and acknowledged that there are no oral agreements between the parties hereto affecting this Lease 
and  this  Lease  constitutes  the  parties’  entire  agreement  with  respect  to  the  leasing  of  the  Premises  and  supersedes  and  cancels  any  and  all  previous 
negotiations, arrangements, brochures, agreements and understandings, if any, between the parties hereto or displayed by Landlord to Tenant with respect

the Base Rent, Additional Rent and other sums to be paid by Tenant or Tenant’s other obligations pursuant to this Lease, or reduce any rights of Tenant

acknowledge and deliver such amendment to Landlord within ten (10) days after Tenant’s receipt thereof.

29.16 Right to Lease. Landlord reserves the absolute right to effect such other tenancies in the Project as Landlord in the exercise of its sole 
business judgment shall determine to best promote the interests of the Building or Project. Tenant does not rely on the fact, nor does Landlord represent,

regard to Rent and other charges to be paid by Tenant pursuant to this Lease (collectively, a “Force Majeure”), notwithstanding anything to the contrary 
contained in this Lease, shall excuse the performance of such party for a period equal to any such prevention, delay or stoppage and, therefore, if this Lease 
specifies  a  time  period  for  performance  of  an  obligation  of  either  party,  that  time  period  shall  be  extended  by  the  period  of  any  delay  in  such  party’s 
performance caused by a Force Majeure.

including reasonable attorneys’ fees, incurred by the prevailing party therein shall be paid by the other party, which obligation on the part of the other party 
shall  be  deemed  to  have  accrued  on  the  date  of  the  commencement  of  such  action  and  shall  be  enforceable  whether  or  not  the  action  is  prosecuted  to 
judgment.

29.23 Governing Law; WAIVER OF TRIAL BY JURY. This Lease shall be construed and enforced in accordance with the laws of the State 
of California. Landlord and Tenant agree that any disputes arising in connection with this Lease (including but not limited to a determination of any and all

Part 2, Title 8, Chapter 6 (§§ 638 et. seq.) of the California Code of Civil Procedure, or any successor California statute governing resolution of disputes by 
a  court  appointed  referee.  Nothing  within  this  Section  29.23  shall  apply  to  an  unlawful  detainer  action.  LANDLORD  AND  TENANT  EACH 
ACKNOWLEDGES THAT IT IS AWARE OF AND HAS HAD THE ADVICE OF COUNSEL OF ITS CHOICE WITH RESPECT TO ITS RIGHT TO 
TRIAL BY JURY, AND, TO THE EXTENT PERMITTED BY LAW, EACH PARTY DOES HEREBY EXPRESSLY AND KNOWINGLY WAIVE AND 
RELEASE  ALL  SUCH  RIGHTS  TO  TRIAL  BY  JURY  IN  ANY  ACTION,  PROCEEDING  OR  COUNTERCLAIM  ARISING  OUT  OF  OR  IN  ANY 
WAY CONNECTED WITH THIS LEASE. The waiver of trial by jury in the immediately preceding Section 29.23 is voluntary and intentionally made by 
Landlord and Tenant.

connection with the negotiation of this Lease, excepting only the real estate brokers or agents specified in Section 13 of the Summary (the “Brokers”), and 
that they know of no other real estate broker or agent who is entitled to a commission in connection with this Lease. Each party agrees to indemnify and 
defend  the  other  party  against  and  hold  the  other  party  harmless  from  any  and  all  claims,  demands,  losses,  liabilities,  lawsuits,  judgments,  costs  and 
expenses (including without limitation reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing

separate written agreement between Landlord and the Brokers.

not dependent and Tenant hereby expressly waives the benefit of any statute to the contrary; and, except as otherwise expressly provided for herein, Tenant

counterpart to this Lease will be deemed the equivalent of the delivery of the original executed instrument. This Lease may be executed in so-called “pdf” 
format and each party has the right to rely upon a pdf counterpart of this Sublease signed by the other party to the same extent as if such party had received 
an  original  counterpart.  Counterparts  may  also  be  delivered  via  electronic  signature  complying  with  the  U.S.  federal  ESIGN  Act  of  2000,  (e.g., 
www.docusign.com or echosign, etc.) and any counterpart so delivered shall be deemed to have been duly and validly delivered, valid and effective for all 
purposes and binding upon the parties hereto.

29.29 Confidentiality. Tenant acknowledges that the content of this Lease and any related documents are confidential information. Tenant shall 
keep  such  confidential  information  strictly  confidential  and  shall  not  disclose  such  confidential  information  to  any  person  or  entity  other  than  Tenant’s 
financial, legal, and space planning consultants, or its directors, officers, employees, attorneys, accountants, prospective lenders, prospective purchasers,

Exchange Commission, the rules of any public exchange upon which Tenant’s shares are from time to time traded, or in connection with a stock or debt 
offering. Additionally, Tenant shall have the right to deliver a copy of this Lease to any proposed subtenant or assignee (with, in the case of a subtenant, 
economic terms redacted), provided such subtenant or assignee agrees to keep the contents hereof confidential. Notwithstanding the foregoing, the parties 
acknowledge that Landlord may use the name of Tenant without Tenant’s consent (i) on the Building directory, and (ii) to the extent that Tenant is only 
referenced by name as a customer or tenant of Landlord, in investor presentations and earnings calls or earnings related releases, and in connection with the 
marketing  efforts  of  Landlord  or  any  real  estate  broker  or  agent  on  Landlord’s  behalf  with  respect  to  the  proposed  leasing,  financing,  sale  or  other 
conveyance of the Building, or any portion thereof. This provision shall survive the expiration or earlier termination of this Lease for one (1) year.

29.30  Renovations.  It  is  specifically  understood  and  agreed  that  Landlord  has  made  no  representation  or  warranty  to  Tenant  and  has  no 
obligation and has made no promises to alter, remodel, improve, renovate, repair or decorate the Premises, Buildings, Project, or any part thereof and that 
no representations respecting the condition of the Premises, the Buildings, or Project have been made by Landlord to Tenant except as specifically set forth 
herein  or  in  the  Work  Letter.  However,  Landlord  may  during  the  Lease  Term  renovate,  improve,  alter,  or  modify  (collectively,  the  “Renovations”)  the 
Project  and/or  the  Buildings,  including  without  limitation,  the  Parking  Facilities,  Common  Areas,  Building  Systems  and/or  Building  Structure,  which 
Renovations may include, without limitation, (i) modifying the Common Areas and tenant spaces to comply with Applicable Laws, including regulations 
relating to the physically disabled, seismic conditions, and Project safety and security, and (ii) installing new floor covering, lighting, and wall coverings in 
the Building Common Areas, and in connection with any Renovations, Landlord may, among other things, erect scaffolding or other necessary structures in 
the Project, limit or eliminate access to portions of the Project, including portions of the Common Areas, or perform work in the Project, which work may 
create noise, dust or leave debris in the Buildings. Landlord shall use commercially reasonable efforts to undertake and complete any Renovations in a 
manner which does not materially, adversely affect Tenant’s use of or access to the Premises. Notwithstanding the foregoing, Tenant hereby agrees that 
such  Renovations  and  Landlord’s  actions  in  connection  with  such  Renovations  shall  in  no  way  constitute  a  constructive  eviction  of  Tenant  nor  entitle 
Tenant  to  any  abatement  of  Rent.  Landlord  shall  have  no  responsibility  or  for  any  reason  be  liable  to  Tenant  for  any  direct  or  indirect  injury  to  or 
interference with Tenant’s business arising from the Renovations, nor shall Tenant be entitled to any compensation or damages from Landlord for loss of 
the use of the whole or any part of the Premises or of Tenant’s personal property or improvements resulting from the Renovations or Landlord’s actions in 
connection  with  such  Renovations,  or  for  any  inconvenience  or  annoyance  occasioned  by  such  Renovations  or  Landlord’s  actions,  provided  that  the 
foregoing shall not limit Landlord’s liability, if any, pursuant to Applicable Law for personal injury and property damage to the extent caused by the gross 
negligence or willful misconduct of Landlord, its agents, employees or contractors.

29.31 No Violation. Tenant hereby warrants and represents that neither its execution of nor performance under this Lease shall cause Tenant to 
be in violation of any agreement, instrument, contract, law, rule or regulation by which Tenant is bound, and Tenant shall protect, defend, indemnify and 
hold Landlord harmless against any claims, demands, losses, damages, liabilities, costs and expenses, including, without limitation, reasonable attorneys’ 
fees and costs, arising from Tenant’s breach of this warranty and representation.

installation of any such Lines (such consent not to be unreasonably withheld), use an experienced and qualified contractor approved in writing by Landlord 
(such approval not to be unreasonably withheld), and comply with all of the other provisions of Articles 7 and 8 of this Lease, (ii) an acceptable amount of 
space for additional Lines shall be maintained for future occupants of the Project, as determined in Landlord’s reasonable opinion, (iii) the Lines (including 
riser  cables)  shall  be  appropriately  insulated  to  prevent  excessive  electromagnetic  fields  or  radiation,  and  shall  be  surrounded  by  a  protective  conduit 
reasonably  acceptable  to  Landlord,  (iv)  any  Lines  servicing  the  Premises  shall  comply  with  all  Applicable  Laws,  (v)  as  a  condition  to  permitting  the 
installation of new Lines, Landlord may require that Tenant remove existing Lines located in or serving the Premises that will no longer be used by Tenant

that Tenant remove any Lines located in or serving the Premises which are installed in violation of these provisions, or which are at any time in violation of 
any Applicable Laws or represent a dangerous or potentially dangerous condition. Upon the expiration of the Lease Term, or immediately following any 
earlier termination of this Lease, Tenant shall, at Tenant’s sole cost and expense, remove all Lines installed by Tenant, and repair any damage caused by 
such removal.

installation, alteration, repair, maintenance, furnishing, operation, adjustment or removal of any such services, equipment or facilities; and (iii) any contract 
or  other  agreement  between  Tenant  and  Provider  shall  be  independent  of  this  Lease,  the  obligations  of  Tenant  hereunder,  and  the  rights  of  Landlord 
hereunder, and, without limiting the foregoing, no default or failure of Provider with respect to any such services, equipment or facilities, or under any 
contract or agreement relating thereto, shall have any effect on this Lease or give to Tenant any offset or defense to the full and timely performance of its 
obligations  hereunder,  or  entitle  Tenant  to  any  abatement  of  rent  or  additional  rent  or  any  other  payment  required  to  be  made  by  Tenant  hereunder,  or 
constitute any accrual or constructive eviction of Tenant, or otherwise give rise to any other claim of any nature against Landlord.

resulting from such subdivision.

-60-

 
29.35.2  The  Other  Improvements.  If  portions  of  the  Project  or  property  adjacent  to  the  Project  (collectively,  the  “Other 
Improvements”) are owned by an entity other than Landlord, Landlord, at its option, may enter into an agreement with the owner or owners of any or all 
of  the  Other  Improvements  to  provide  (i)  for  reciprocal  rights  of  access  and/or  use  of  the  Project  and  the  Other  Improvements,  (ii)  for  the  common 
management, operation, maintenance, improvement and/or repair of all or any portion of the Project and the Other Improvements, (iii) for the allocation of 
a portion of the Direct Expenses to the Other Improvements and the operating expenses and taxes for the Other Improvements to the Project, and (iv) for 
the use or improvement of the Other Improvements and/or the Project in connection with the improvement, construction, and/or excavation of the Other 
Improvements and/or the Project. Nothing contained herein shall be deemed or construed to limit or otherwise affect Landlord’s right to convey all or any 
portion of the Project or any other of Landlord’s rights described in this Lease.

29.36 Water Sensors. In connection with any Tenant Improvements or Alterations to be installed in the Premises where water is utilized (such as 
sinks, pipes, faucets, water heaters, autoclaves, coffee machines, ice machines, water dispensers and water fountains), Tenant acknowledges and agrees that 
Landlord  and  Tenant  will  consider,  as  part  of  the  Landlord  approval  process  for  the  plans  and  specifications  of  any  such  Tenant  Improvements  or 
Alterations, whether to install “Water Sensors” in locations that may be reasonably expected to detect a leak occurring in the Premises. As used herein, 
“Water Sensors” are either web-enabled wireless water leak sensor devices designed to alert the Tenant on a twenty-four (24) hour seven (7) day per week 
basis if a water leak is occurring in the Premises (which water sensor device(s) located in the Premises shall be referred to herein as “Web-Enabled Water 
Sensors”) or non web-enabled water leak sensor devices of a model and specifications to be approved by Landlord (“Non Web-Enabled Water Sensors”). 
To the extent Landlord and Tenant agree that Tenant will install such Water Sensors, Tenant shall, at Tenant’s sole cost and expense, be responsible for 
installing the Water Sensors. If Tenant installs Non Web-Enabled Water Sensors that are determined by virtue of their performance to be deficient (i.e., fail 
to detect a water leak with the same or similar speed as the web enabled Water Sensors, or in any way fails to detect a water leak), then Tenant shall, upon 
Landlord’s  written  demand,  at  Tenant’s  sole  cost  and  expense,  remove  the  Non  Web-Enabled  Water  Sensors  and  install  Web-Enabled  Water  Sensors  in 
accordance with this Section 29.36. With respect to the installation of any such Water Sensors, Tenant shall use an experienced and qualified contractor 
reasonably approved by Landlord and comply with all of the other provisions of Article 8 of this Lease. Tenant shall, at Tenant’s sole cost and expense, 
pursuant to Article 7 of this Lease keep any Water Sensors located in the Premises in good working order, repair and condition at all times during the Lease 
Term and comply with all of the other provisions of Article 7 of this Lease. Notwithstanding any provision to the contrary contained herein, Landlord has 
neither an obligation to monitor, repair or otherwise maintain the Water Sensors, nor an obligation to respond to any alerts it may receive from the Water 
Sensors or which may be generated from the Water Sensors. Upon the expiration of the Lease Term, or immediately following any earlier termination of 
this Lease, Tenant shall leave the Water Sensors in place together with all necessary user information such that the same may be used by a future occupant 
of the Premises (e.g., the Water Sensors shall be unblocked and ready for use by a third-party).

29.37 Utility Billing Information. In the event that Landlord permits Tenant to contract directly for the provision of electricity, gas and/or water 
services  to  the  Premises  with  the  third-party  provider  thereof,  Tenant  shall  provide  Landlord  with  a  copy  of  each  invoice  received  from  the  applicable 
utility  provider  promptly  following  Tenant’s  receipt  thereof.  Landlord  may  be  required  to  disclose  information  concerning  Tenant’s  energy  usage  at  the 
Project  to  certain  third  parties,  including,  without  limitation,  prospective  purchasers,  lenders  and  tenants  of  the  Project  (the  “Tenant  Energy  Use 
Disclosure”). Tenant hereby consents to all such Tenant Energy Use Disclosures, and Landlord shall use commercially reasonable efforts to notify Tenant 
of any Tenant Energy Use Disclosures made by Landlord. Further, Tenant hereby releases Landlord from any and all losses, costs, damages, expenses and 
liabilities relating to, arising out of and/or resulting from any Tenant Energy Use Disclosure. The terms of this Section 29.37 shall survive the expiration or 
earlier termination of this Lease.

29.38 Green Cleaning/Recycling Program. Tenant shall cooperate if and to the extent Landlord implements a green cleaning program and/or 
recycling or waste management program for the Project, and Tenant hereby agrees that the reasonable costs associated with any such green cleaning and/or 
recycling program shall be included in Operating Expenses.

29.39 LEED Certification. Landlord may, in Landlord’s sole and absolute discretion, elect to apply to obtain or maintain a LEED certification 
for  the  Project  (or  portion  thereof),  or  other  applicable  certification  in  connection  with  Landlord’s  sustainability  practices  for  the  Project  (as  such 
sustainability practices are to be determined by 

-61-

 
Landlord,  in  its  sole  and  absolute  discretion,  from  time  to  time).  In  the  event  that  Landlord  elects  to  maintain  the  existing  LEED  certification  for  the 
Project, Tenant shall, at Tenant’s sole cost and expense, promptly cooperate with the Landlord’s efforts in connection therewith and provide Landlord with 
any documentation it may need in order to maintain the aforementioned certification (which cooperation may include, but shall not be limited to, Tenant 
complying  with  certain  standards  pertaining  to  the  purchase  of  materials  used  in  connection  with  any  Alterations  or  improvements  undertaken  by  the 
Tenant in the Project (other than with respect to laboratory areas), the sharing of documentation pertaining to any Alterations or improvements undertaken 
by  Tenant  in  the  Project  with  Landlord,  and  the  sharing  of  Tenant’s  billing  information  pertaining  to  trash  removal  and  recycling  related  to  Tenant’s 
operations in the Project).

29.40 Approvals. Whenever this Lease requires an approval, consent, determination, selection or judgment by either Landlord or Tenant, unless 
another  standard  is  expressly  set  forth,  such  approval,  consent,  determination,  selection  or  judgment  and  any  conditions  imposed  thereby  shall  be 
reasonable and shall not be unreasonably withheld or delayed.

29.41 Prohibited Persons; Foreign Corrupt Practices Act and Anti-Money Laundering. Neither (i) Tenant nor any of its officers, directors 
or managers, or (ii) to Tenant’s knowledge, any of Tenant’s affiliates, nor any of their respective members, partners, other equity holders (excluding any 
holders of any publicly traded stock or other equity interests of Tenant, if any), officers, directors or managers is, nor prior to or during the Lease Term, will 
they become a person or entity with whom U.S. persons or entities are restricted from doing business under (a) the Patriot Act (as defined below), (b) any 
other requirements contained in the rules and regulations of the Office of Foreign Assets Control, Department of the Treasury (“OFAC”) (including any 
“blocked” person or entity listed in the Annex to Executive Order Nos. 12947, 13099 and 13224 and any modifications thereto or thereof or any other 
person or entity named on OFAC’s Specially Designated Blocked Persons List) or (c) any other U.S. statute, Executive Order (including the September 24, 
2001, Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit or Support Terrorism) or other 
governmental action (collectively, “Prohibited Persons”). Tenant is not entering into this Lease, directly or indirectly, in violation of any laws relating to 
drug trafficking, money laundering or predicate crimes to money laundering. As used herein, “Patriot Act” shall mean the USA Patriot Act of 2001, 107 
Public  Law  56  (October  26,  2001)  and  all  other  statutes,  orders,  rules  and  regulations  of  the  U.S.  government  and  its  various  executive  departments, 
agencies and offices interpreting and implementing the Patriot Act.

TENANT WORK LETTER

THIS  TENANT  WORK  LETTER  (this  “Work  Letter”)  is  attached  to  and  made  a  part  of  that  certain  Lease  (the  “Lease”)  between  KRE 
EXCHANGE  OWNER  LLC,  a  Delaware  limited  liability  company  (“Landlord”),  and  VIR  BIOTECHNOLOGY,  INC.,  a  Delaware  corporation 
(“Tenant”). All capitalized terms used but not defined herein shall have the respective meanings given such terms in the Lease. This Work Letter sets forth 
the terms and conditions relating to the construction of Tenant’s Improvements (defined below) in the Premises.

SECTION 2

BASE BUILDING

Subject to the terms and conditions of this Work Letter, Tenant hereby accepts the base, shell and core (i) of the Premises and (ii) of the floor(s) 
of the Building on which the Premises are located (collectively, the “Base Building”), in its current “AS IS” condition existing as of the date of the Lease 
and  the  Lease  Commencement  Date.  Tenant  shall  be  entitled  to  an  improvement  allowance  in  the  maximum  aggregate  amount  of  Two  Million  Three 
Hundred Forty-Three Thousand, One Hundred Eighty Dollars ($2,343,180.00) (i.e., $17.50 per rentable square foot of the Premises) (the “Base Building 
Improvement Allowance”) to be used by Tenant solely to pay for the construction of certain improvements to the Base Building as are more particularly 
identified  in  Attachment 1  to  this  Work  Letter  (which  required  improvements  are  referred  to  here  as  the  “Base  Building  Improvement  Additions”)  . 
Subject to Landlord’s obligation to pay to Tenant the Base Building Improvement Allowance in accordance with the terms and conditions of this Work 
Letter, Tenant shall be solely liable for all soft and hard costs associated with the Base Building Improvement Additions. Except for the Base Building 
Improvement Allowance and the Tenant Improvement Allowance set forth below, Landlord shall not be obligated to make or pay for any alterations or 
improvements to the Premises or the Building.

For the sake of clarity, the base building condition of the Base Building to be delivered by Landlord to Tenant on the Lease Commencement Date 
is identified in the matrix (outlining existing base building conditions of the Base Building, including, inter alia, power, emergency power, lab exhaust, lab 
air supply and office air supply) attached hereto as Attachment 2 to this Work Letter (the “Base Building Delivery Condition”). Tenant acknowledges and 
agrees that Attachment 1 identifies conditions that are the Tenant’s responsibility to install (and, as such, are expressly not included in Attachment 2 as 
being included in the Base Building Delivery Condition), subject to reimbursement to the extent of the Base Building Improvement Allowance.

Landlord acknowledges that certain of Tenant’s laboratory improvements to a portion of the Premises require additional emergency power, and 
Landlord commits to work cooperatively with Tenant and its consultants to identify one or more solutions for Tenant’s additional power needs; provided, 
however,  the  cost  of  designing  and  installing  the  Base  Building  infrastructure  (in  excess  of  the  portion  of  the  Base  Building  Improvement  Allowance 
attributable to Tenant’s additional power needs) to achieve the availability of additional power capacity to the Premises shall be borne solely by Tenant (i.e., 
the cost of all upgrades, alterations and/or additions beyond those described in the Base Building Delivery Condition shall be paid solely by Tenant).

SECTION 3

ALLOWANCE; TENANT IMPROVEMENTS

3.1 Allowance. In addition to the Base Building Improvement Allowance, Tenant shall be entitled to a one-time allowance in an amount not to 
exceed  $36,151,920.00  with  respect  to  the  Premises  in  the  aggregate  (the  “Tenant  Improvement  Allowance”  and  together  with  the  Base  Building 
Improvement Allowance, the “Allowance”),  for  the  costs  relating  to  the  design,  permitting  and  construction  of  the  Improvements  to  be  constructed  by 
Tenant  that  are  to  be  permanently  affixed  in  the  Premises  (as  applicable,  the  “Tenant  Improvements”).  In  clarification  of  the  foregoing,  Tenant 
acknowledges and agrees that the Tenant Improvement Allowance will be used to pay for the cost of Tenant Improvements to the tenth (10th),  eleventh 
(11th) and twelfth (12th) floors (i.e., which floors are the lab floors), and in no event will Landlord be obligated to make disbursements pursuant to this Work 
Letter for an applicable portion of 

EXHIBIT 1.1.1-2
-1-

 
the Premises in an amount that exceeds the amount of the Tenant Improvement Allowance applicable to such portion of the Premises; provided, however, 
Tenant  may  use  up  to  $1,000,000.00  of  the  Tenant  Improvement  Allowance  for  improvements  to  the  non-lab  floors.  Notwithstanding  anything  to  the 
contrary set forth herein, no portion of the Allowance shall be disbursed by Landlord after twenty-four (24) months after the Lease Commencement Date; 
and any portion, if any, of the Allowance that is not disbursed by Landlord on or before such date shall revert to Landlord and Tenant shall have no rights 
thereto.

3.2 Disbursement of the Allowance.

following items and costs (collectively the “Allowance Items”):

(a) Allowance Items.  Except  as  otherwise  set  forth  in  this  Work  Letter,  the  Allowance  shall  be  disbursed  by  Landlord  only  for  the 

below);

(i) Payment of the fees of the Architect, Contractor, Tenant Agents and the Building Consultants (as those terms are defined 

(ii) The payment of plan check, permit and license fees relating to the construction of the Tenant Improvements;

inspection costs, trash removal costs, and contractors’ fees and general conditions;

(iii)  The  cost  of  construction  of  the  Tenant  Improvements,  including,  without  limitation,  after  hours  charges,  testing  and 

(iv) The cost of any changes to the Building, any portion of the Premises or any building systems serving any portion of the 
Premises  when  such  changes  are  required  by  the  Construction  Drawings,  such  cost  to  include  all  architectural  and/or  engineering  fees  and  expenses 
incurred in connection therewith;

(collectively, the “Code”);

(v) The cost of any changes to the Construction Drawings or Tenant Improvements required by applicable building codes 

(vi) The fees of Tenant’s project manager (if any) up to a maximum sum of $250,000.00;

(vii) The costs of Landlord’s charges and fees (Section 2.6) and Landlord’s Management Fee (defined below); and

(viii) Sales and use taxes and Title 24 fees.

For the sake of clarity, Tenant acknowledges and agrees that Tenant and Tenant’s Agents will accept sole responsibility for ADA and building 
code  compliance  for  all  improvements  designed  by  Tenant’s  Agents;  provided,  however,  Landlord  accepts  responsibility  for  ADA  and  building  code 
compliance for the Base Building of the Building and exterior areas (including path of travel from the public street to the entry of the Premises) limited to 
the existing conditions. If Tenant’s use of the Premises or any Base Building Improvement Additions triggers a change in path of travel, Tenant shall be 
responsible for any ADA and building code compliance triggered by such change in path of travel.

(b) Disbursement of Allowance. During the construction of the applicable portion of the Base Building Improvement Additions and 
the  Tenant  Improvements,  Landlord  shall  make  monthly  disbursements  of  the  Base  Building  Improvement  Allowance  and  the  Tenant  Improvement 
Allowance, as applicable, to reimburse Tenant for Allowance Items with respect to such Tenant Improvements and shall authorize the release of funds as 
follows, and otherwise in accordance with such disbursement procedures as Landlord shall reasonably require from time to time.

(i) Progress Payment Disbursements.

(A) On or before the fifth (5th) day of each calendar month during the construction of the Tenant Improvements in 
the  applicable  portion  of  the  Premises  (or  such  other  date  as  Landlord  may  designate),  Tenant  shall  deliver  to  Landlord  with  respect  to  such  Tenant 
Improvements: (A) a request for payment from Contractor (defined below) approved by Tenant, in the form of an AIA G702/G703 application for payment 
(or comparable forms 

EXHIBIT 1.1.1-2
-2-

 
reasonably  approved  by  Landlord),  showing  the  schedule,  by  trade,  of  percentage  of  completion  of  the  applicable  Tenant  Improvements,  detailing  the 
portion of the work completed and the portion not completed (each, a “Payment Request”); (B) invoices from all of Tenant’s Agents (defined below) for 
labor rendered and materials delivered to the Premises; (C) executed conditional mechanic’s lien releases from all of Tenant’s Agents who have lien rights 
with respect to the subject Payment Request (along with unconditional mechanics’ lien releases with respect to payments made pursuant to Tenant’s prior 
submission hereunder) in compliance with all applicable laws as reasonably determined by Landlord, including without limitation all applicable provisions 
of California Civil Code Sections 8132 - 8138; (D) a copy of the check(s) or online banking records which Tenant issued to pay the requested sums to 
Tenant’s Agents; and (E) all other information reasonably requested by Landlord (collectively, the “Payment Request Supporting Documentation”).

(B)  Within  forty-five  (45)  days  after  Tenant’s  delivery  to  Landlord  of  all  Payment  Request  Supporting 
Documentation,  Landlord  shall  deliver  a  check  to  Tenant  made  payable  to  Tenant  (or,  at  Landlord’s  election,  by  wire  transfer  of  immediately  available 
funds) in payment of the lesser of: (x) the amount so requested by Tenant in its Payment Request, less a ten percent (10%) retention (the aggregate amount 
of  such  retentions  to  be  known  as  the  “Final  Retention”),  and  (y)  the  balance  of  any  remaining  available  portion  of  the  applicable  Allowance  (not 
including the Final Retention), provided that if Landlord, in good faith, disputes any item in a Payment Request based on non-compliance of any work with 
the Approved Working Drawings (defined below) or due to any substandard work or for any other reason, and delivers a written objection to such item 
setting forth with reasonable particularity Landlord’s reasons for its dispute (a “Draw Dispute Notice”), Landlord may deduct the amount of such disputed 
item from the payment. Landlord and Tenant shall, in good faith, endeavor to diligently resolve any such dispute. Landlord’s payment of such amounts 
shall  not  be  deemed  Landlord’s  approval  or  acceptance  of  the  work  furnished  or  materials  supplied  as  set  forth  in  Tenant’s  Payment  Request. 
Disbursements of soft costs and costs not to be paid through the Contractor shall be made based upon submittal by Tenant of satisfactory documentation for 
the same concurrently with Tenant’s submittal of its Payment Request, and payment shall be made no later than forty-five (45) days after submittal of such 
documentation, provided that in no event will Landlord be obligated to pay any amounts in excess of the applicable Allowance.

(ii) Final Disbursement. Subject to the provisions of this Work Letter, following the final completion of construction of the 
Tenant Improvements in the applicable portion of the Premises, Landlord shall deliver to Tenant a check made payable to Tenant (or, at Landlord’s election, 
by wire transfer of immediately available funds) in the amount of the Final Retention for such portion of the Premises, provided that (A) Tenant delivers to 
Landlord for the entirety of the Tenant Improvements in such portion of the Premises properly executed unconditional mechanics’ lien releases from all of 
Tenant’s Agents in compliance with all applicable laws, as reasonably determined by Landlord, including without limitation compliance with all applicable 
provisions  of  California  Civil  Code  Sections  8132  -  8138;  (B)  Landlord  has  determined  that  no  substandard  work  exists  which  adversely  affects  the 
mechanical, electrical, plumbing, heating, ventilating and air conditioning, life-safety or other systems of the Building or any portion of the Premises), the 
curtain wall of the Building or the structure or exterior appearance of the Building; (C) Architect delivers to Landlord a certificate, in a form reasonably 
acceptable to Landlord, certifying that the construction of such Tenant Improvements has been substantially completed in accordance with the Approved 
Working Drawings; (D) Tenant supplies Landlord with evidence that all governmental approvals required for Tenant to legally occupy such portion of the 
Premises have been obtained; and (E) Tenant has fulfilled its Completion Obligations (defined below) and has otherwise complied with Landlord’s standard 
“close-out” requirements regarding city approvals, closeout tasks, closeout documentation regarding the general contractor, financial close-out matters, and 
Tenant’s vendors, and as set forth in the tenant improvement guidelines (the “Tenant Improvement Guidelines”) to be provided to Tenant by Landlord. 
Disbursements of soft costs and costs not to be paid through Contractor shall be made based upon submittal by Tenant of satisfactory documentation for the 
same,  and  payment  shall  be  made  concurrently  with  payment  of  the  Final  Retention,  provided  that  in  no  event  will  Landlord  be  obligated  to  pay  any 
amounts in excess of the applicable Allowance.

(c) Standard Tenant Improvement Package. Landlord has established specifications for the Building standard components to be used in 
the construction of the Tenant Improvements in the Premises (collectively, the “Building Standards”), which Building Standards have been provided to 
Tenant by Landlord. The quality of the Tenant Improvements shall be equal to or of greater quality than the quality of the Building Standards.

EXHIBIT 1.1.1-2
-3-

 
(b) Exhaust Shaft Reopening. The parties acknowledge that in connection with the initial construction of the Building, Dropbox caused 
an exhaust shaft that ran between the 11th floor and the roof of the North Tower to be filled and taken out of service. Landlord has agreed to allow Tenant’s 
Contractor  (defined  below)  to  undertake  the  work  of  restoring  that  shaft  to  a  useable  condition  (as  part  of  the  Base  Building  Improvement  Allowance, 
specifically # 9 in Attachment 1). Tenant has provided Landlord with the plans and specifications for such work and the Contractor’s estimate of the cost 
thereof,  and  Landlord  has  previously  approved  the  same.  Tenant  shall  include  the  cost  of  such  work  in  the  Payment  Request  submitted  to  Landlord 
following the completion of such work.

(c) Mechanical Shaft Space. Landlord desires to install mechanical shaft space between the 8th, 9th and 10th floors of the North Tower 
in  the  two  (2)  locations  depicted  in  Attachment 3  attached  hereto  (the  “Mechanical  Shafts”).  Tenant  will  allow  Landlord  to  install  and  pay  for  such 
Mechanical Shafts per a mutually agreed upon work schedule plan established between Landlord and Tenant. Landlord, at its sole cost and expense (in 
addition to and not as part of the Allowance), will relocate the existing conference rooms on floors 8, 9 and 10 to a mutually agreeable location to facilitate 
the  installation  of  the  Mechanical  Shafts,  which  location  has  been  designated  pursuant  to  plans  previously  approved  by  Landlord  and  Tenant.  If  the 
installation of the Mechanical Shafts is not completed by Tenant’s occupancy of such floors, then Landlord will use commercially reasonably efforts to 
complete  the  work  during  Tenant’s  nonregular  business  hours  in  order  to  minimize  impacts  to  the  conduct  of  Tenant’s  business  operations  within  the 
Premises.

(d) Standby Power. Tenant acknowledges and accepts that Landlord will provide to it an allocation of 570 kVA of standby electrical 
power for the Premises. Tenant’s use of such standby power must not exceed its allocated share of such standby power. If Tenant’s consumption of the 
standby  power  regularly  exceeds  98%  of  its  allocated  share  (i.e.,  such  98%  threshold  being  558.6  kVA)  for  the  Premises,  then  Tenant  shall,  at  its  sole 
expense, shed load on the standby power system to ensure that its usage will remain below such allocated capacity. As used herein, “shedding load” may 
consist of disconnecting equipment from the standby system, timing the use of equipment for non-peak hours, recircuiting to a power system with available 
capacity and other appropriate actions to reduce peak usage of standby electrical power. Tenant acknowledges and agrees that it shall be solely responsible 
for monitoring and managing at all times its consumption level of standby power; Landlord shall have no liability whatsoever for Tenant’s excess use of 
standby  power  (including,  without  limitation,  any  shortfall  or  lack  of  available  standby  power  in  excess  of  Tenant’s  allocated  share).  Actual  electrical 
consumption is metered and monitored through Landlord’s building automation system (BAS), and Landlord will allow Tenant read-only access to Tenant’s 
actual electrical usage data in order to facilitate Tenant’s monitoring and managing of its consumption levels of standby power.

(e)  Emergency  Power.  Tenant  acknowledges  and  accepts  that  Landlord  will  provide  to  it  an  allocation  of  35  kVA  of  emergency 
electrical power for the Premises. Tenant’s use of emergency power shall be limited to Life Safety code-related functions. Tenant acknowledges and agrees 
that it shall be solely responsible for monitoring and managing at all times its connected load to such emergency power system; Landlord shall have no 
liability  whatsoever  for  Tenant’s  excess  use  of  emergency  power  (including,  without  limitation,  any  shortfall  or  lack  of  available  emergency  power  in 
excess of Tenant’s allocated share). If Tenant’s connected load to such emergency power exceeds its allocated share for the Premises, then Tenant shall, at 
its sole expense, shed load on the emergency power system to ensure that its usage will be below such allocated capacity.

shall be known collectively as the “Construction Drawings.” All Construction Drawings shall comply with the drawing format and specifications as set 
forth  in  the  Tenant  Improvement  Guidelines  and  shall  be  subject  to  Landlord’s  approval  (as  approved  pursuant  to  Sections  3.2  and  3.3  below,  the 
“Approved Working Drawings”). All MEP drawings must be fully engineered and cannot be prepared on a “design-build” basis. Tenant and Architect 
shall verify, in the field, the dimensions and conditions as shown on the relevant portions of the base building plans, and Tenant and Architect will be solely 
responsible for the same, and Landlord shall have no responsibility in connection therewith. Landlord’s review of the Construction Drawings shall be for its 
sole purpose and shall not obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Accordingly, notwithstanding 
that  any  Construction  Drawings  are  reviewed  by  Landlord  or  its  space  planner,  architect,  engineers  and  consultants,  and  notwithstanding  any  advice  or 
assistance that may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants, Landlord shall have no liability 
whatsoever  in  connection  therewith  and  shall  not  be  responsible  for  any  omissions  or  errors  contained  in  the  Construction  Drawings  or  the  Approved 
Working  Drawings,  and  Tenant’s  waiver  and  indemnity  set  forth  in  the  Lease  shall  specifically  apply  to  the  Construction  Drawings  and  the  Approved 
Working Drawings.

4.2 Space Plan. Tenant shall supply Landlord for Landlord’s (and Landlord’s) review and approval four (4) hard copies and one (1) electronic 
copy  of  its  space  plan  for  the  applicable  portion  of  the  Premises  signed  by  Tenant  (the  “Space  Plan”)  before  any  architectural  working  drawings  or 
engineering drawings therefor have been commenced. The Space Plan shall include a layout and designation of all offices, rooms and other partitioning, 
laboratory  improvements,  if  applicable,  the  intended  use  thereof,  and  equipment  to  be  contained  therein.  Landlord  may  request  clarification  or  more 
specific drawings for special use items not included in the Space Plan. Landlord shall advise Tenant within ten (10) business days after Landlord’s receipt 
of the Space Plan (or, if applicable, such additional information requested by Landlord pursuant to the provisions of the immediately preceding sentence) if 
the same is approved or is unsatisfactory or incomplete in any respect. If Tenant is so advised, Tenant shall promptly cause the Space Plan to be revised to 
correct any deficiencies or other matters Landlord may reasonably require. If Landlord fails to respond within such ten (10) Business Day period, Tenant 
shall deliver Landlord an additional notice requesting approval and if Landlord thereafter fails to respond within three (3) business days of receipt of such 
additional notice, Landlord will be deemed to have approved such Space Plan.

4.3  Working  Drawings.  After  the  Space  Plan  has  been  approved  (or  deemed  approved)  by  Landlord  (and  Tenant),  Tenant  shall  supply  the 
Architect and the Building Consultants with a complete listing of standard and non-standard equipment and specifications, including, without limitation, 
B.T.U. calculations, electrical requirements and special electrical receptacle requirements for the applicable portion of the Premises, to enable the Architect 
and the Building Consultants to complete the Working Drawings (as defined below). Tenant shall cause the Architect and the 

EXHIBIT 1.1.1-2
-5-

 
 
Building Consultants to promptly complete the architectural and engineering drawings for such portion of the Premises, and Architect shall compile a fully 
coordinated set of architectural, structural, mechanical, electrical and plumbing working drawings in a form which is complete (i.e., fully supported with 
calculations and other back up as requested by Landlord and sufficient to allow subcontractors to bid on the work and to submit to the City and County of 
San Francisco Department of Building Inspection to obtain all applicable permits) (collectively, the “Working Drawings”) and shall submit four (4) hard 
copies and one (1) electronic copy signed by Tenant to Landlord for Landlord’s (and Landlord’s) review and approval. Landlord shall advise Tenant within 
ten  (10)  business  days  after  Landlord’s  receipt  of  the  Working  Drawings  if  Landlord,  in  good  faith,  determines  that  the  same  are  approved  or  are 
unsatisfactory  or  incomplete.  If  Tenant  is  advised  that  the  Working  Drawings  are  unsatisfactory  or  are  incomplete,  Tenant  shall  promptly  revise  the 
Working Drawings to correct any deficiencies or other matters Landlord may reasonably require. The ten (10) Business Day period shall only commence 
when the Working Drawings are complete and fully supported with calculations and other back up as requested by Landlord. If Landlord fails to respond 
within such ten (10) Business Day period, Tenant shall deliver Landlord an additional notice requesting approval and if Landlord thereafter fails to respond 
within five (5) business days of receipt of such additional notice, Landlord will be deemed to have approved such Working Drawings. After approval (or 
deemed approval) by Landlord of the Working Drawings, Tenant shall submit the same to the appropriate municipal authorities for all applicable building 
permits.  Tenant  hereby  agrees  that  neither  Landlord  nor  Landlord’s  consultants  shall  be  responsible  for  obtaining  any  building  permit  or  for  obtaining 
interim or final signoffs on such permits and that obtaining the same shall be Tenant’s responsibility; provided that Landlord shall cooperate with Tenant in 
executing  permit  applications  and  other  ministerial  acts  reasonably  necessary  to  enable  Tenant  to  obtain  any  such  permit  or  sign-off.  In  no  event  shall 
Tenant commence any construction work in any portion the Premises prior to Landlord’s written approval of the Construction Drawings therefor and prior 
to the date that all required governmental permits are obtained and copies of all such permits are provided to Landlord.

4.4 Change Orders. Once approved by Landlord, no material change in the Working Drawings may be made without the prior written approval of 
Landlord;  provided  however,  if  the  proposed  change  does  not  materially  affect  the  Building  Structure,  Building  Systems  or  equipment  or  otherwise 
materially affect the Base Building and the cost implications of any such change will be borne one hundred percent (100%) by Tenant, Landlord agrees that 
it will not unreasonably withhold consent to such change. In the event Tenant desires to make any such change, Tenant shall deliver notice of the same to 
Landlord, setting forth in detail the change Tenant desires to make to such Working Drawings. Landlord shall, within seven (7) business days of receipt of 
such  notice,  either  (i)  approve  the  proposed  change,  or  (ii)  disapprove  the  proposed  change  and  deliver  a  notice  to  Tenant  specifying  in  reasonably 
sufficient detail the reasons for Landlord’s disapproval.

4.5 Landlord’s Approval. Landlord’s approval of any matter under this Work Letter may be withheld if Landlord determines that the same would 
violate  any  provision  of  the  Lease  or  this  Work  Letter  or  would  adversely  affect  the  mechanical,  electrical,  plumbing,  heating,  ventilating  and  air 
conditioning, life-safety or other systems of the Building or any portion of the Building (including the Premises, the curtain wall of the Building or the 
structure  or  exterior  appearance  of  the  Building).  Landlord  and  Tenant  acknowledge  and  agree  that,  prior  to  their  mutual  execution  and  delivery  of  the 
Lease,  Tenant  has  been  working  with  Dropbox  and  Landlord,  as  master  landlord,  to  process  plans  for  the  construction  of  alterations  to  the  subleased 
premises to accomplish a build out of the subleased premises, and in connection with that process, Landlord has thus far provided to Tenant the approvals 
identified on Attachment 4 attached hereto (collectively, the “Existing Approvals”). Other than the Existing Approvals, Tenant acknowledges and agrees 
that it must comply with the process described in this Work Letter in connection with obtaining future approvals.

4.6 Landlord’s Costs. Tenant shall be responsible for payment of the reasonable out-of-pocket fees incurred by, and the reasonable out-of-pocket 
cost  of  documents  and  materials  supplied  by,  Landlord  and  Landlord’s  consultants  in  connection  with  the  preparation  and  review  of  the  Construction 
Drawings and otherwise relating to the construction of the Tenant Improvements, not to exceed $15,000.00.

(a)  The  Contractor.  A  general  contractor  selected  by  Tenant  and  approved  in  writing  by  Landlord  shall  be  retained  by  Tenant  to 

(b)  Tenant’s  Agents.  All  subcontractors,  laborers,  materialmen,  and  suppliers  used  by  Tenant  (such  subcontractors,  laborers, 
materialmen, and suppliers, and the Contractor to be known collectively as “Tenant’s Agents”) must be approved in writing by Landlord, such approval 
not to be unreasonably withheld, conditioned or delayed (Landlord will approve or disapprove Tenant’s Agents within ten (10) business days following 
Tenant’s written request, and failure to respond within this period shall be deemed approval of the same), provided that Landlord will require Tenant to 
retain the Building Consultants. All of Tenant’s Agents shall be licensed in the State of California, capable of being bonded and shall use only union labor.

5.2 Construction of Tenant Improvements by Tenant’s Agents.

(a) Construction Contract; Cost Budget; Over-Allowance Payments. Landlord acknowledges that prior to the date of this Lease it has 
received  and  approved  a  copy  of  Tenant’s  executed  construction  contract  and  general  conditions  with  Contractor  (the  “Contract”).  Prior  to  the 
commencement of the construction of any portion of the Tenant Improvements, Tenant shall provide Landlord with a schedule of values consisting of a 
detailed breakdown, by trade, of the final costs to be incurred or which have been incurred, in connection with the design and construction of such Tenant 
Improvements,  which  costs  form  the  basis  for  the  amount  of  the  Contract  (the  “Anticipated Costs”).  Landlord  and  Tenant  shall  determine  the  amount 
equal to the difference between (i) the amount of such Anticipated Costs, and (ii) the amount of the Allowance applicable to such portion of the Premises 
(less any portion thereof already disbursed by Landlord, or in the process of being disbursed by Landlord, on or before the commencement of construction 
of such portion of the Tenant Improvements) (such difference, if any, being the “Anticipated Over-Allowance Amount”). As of the date of this Lease, the 
Anticipated Over-Allowance Amount is projected to be $ 
. Tenant shall pay a percentage of each amount requested by the Contractor or otherwise to be 
disbursed under this Work Letter, which percentage (the “Percentage”) shall be equal to the Anticipated Over- Allowance Amount divided by the amount 
of the applicable Allowance, and such payments by Tenant (the “Over- Allowance Payments”) shall be a condition to Landlord’s obligation to pay any 
amounts from the Allowance (the “Improvement Allowance Payments”). Tenant shall advise Landlord from time to time as such Anticipated Costs are 
further  refined  or  determined  or  the  costs  relating  to  the  design  and  construction  of  the  applicable  Tenant  Improvements  otherwise  change,  and  the 
Anticipated  Over-Allowance  Amount  and  Over-Allowance  Payments  shall  be  adjusted  such  that  the  applicable  Improvement  Allowance  Payments  by 
Landlord  and  applicable  the  Over-  Allowance  Payments  by  Tenant  shall  accurately  reflect  the  then-current  amount  of  the  Anticipated  Costs  for  the 
applicable Tenant Improvements.

(b) Construction Requirements.

(i) Landlord’s  General  Conditions  for  Tenant’s  Agents  and  Tenant  Initial Improvement Work.  Construction  of  the  Tenant 
Improvements  shall  comply  with  the  following:  (A)  the  Tenant  Improvements  shall  be  constructed  in  strict  accordance  with  the  Approved  Working 
Drawings  and  Landlord’s  (and  Landlord’s)  construction  guidelines;  (B)  Tenant’s  Agents  shall  submit  schedules  of  all  work  relating  to  the  Tenant 
Improvements to Landlord and Landlord shall, within five (5) business days of receipt thereof, inform Tenant’s Agents of any changes which are necessary 
thereto, and Tenant’s Agents shall adhere to such corrected schedule; and (C) Tenant shall abide by Landlord’s construction rules for the Project and all 
other  rules  reasonably  made  by  Landlord  and  Landlord’s  Building  manager  with  respect  to  the  use  of  freight,  loading  dock  and  service  elevators,  any 
required  shutdown  of  utilities  (including  life  safety  systems),  storage  of  materials,  coordination  with  other  contractors  working  in  any  portion  of  the 
Building,  and  any  other  matter  in  connection  with  this  Work  Letter,  including,  without  limitation,  the  construction  of  the  Tenant  Improvements.  Tenant 
shall pay to Landlord a fee for Landlord’s design review, processing of Payment Requests, coordination of the Tenant Improvements with Landlord, and 
general oversight (the “Management Fee”) with respect to the Tenant Improvements in an amount equal to Nine Hundred Sixty-Two 

EXHIBIT 1.1.1-2
-7-

 
Thousand  Three  Hundred  Seventy  Seven  and  50/100  Dollars  ($962,377.50)  (i.e.,  2.5%  of  the  Tenant  Improvement  Allowance  and  the  Base  Building 
Improvement Allowance); the Management Fee shall be deducted from the applicable portion of the Allowance on a pro rata basis with each disbursement 
of such portion of the Allowance.

(ii) Indemnity. Tenant’s indemnity of Landlord as set forth in the Lease shall also apply with respect to any and all costs, 
losses, damages, injuries and liabilities related in any way to any act or omission of Tenant or Tenant’s Agents, or anyone directly or indirectly employed 
by any of them, or in connection with Tenant’s nonpayment of any amount arising out of the Tenant Improvements and/or Landlord’s disapproval of all or 
any  portion  of  any  request  for  payment.  Such  indemnity  by  Tenant,  as  set  forth  in  the  Lease,  shall  also  apply  with  respect  to  any  and  all  costs,  losses, 
damages,  injuries  and  liabilities  related  in  any  way  to  Landlord’s  performance  of  any  ministerial  acts  reasonably  necessary  (A)  to  permit  Tenant  to 
complete the Tenant Improvements, and (B) to enable Tenant to obtain any building permit or certificate of occupancy for any portion of the Premises. The 
foregoing indemnity shall not apply to claims caused by the gross negligence or willful misconduct of Landlord, Landlord or its or their members, partners, 
shareholders,  officers,  directors,  agents,  employees  and/or  contractors,  or  to  the  failure  of  Landlord  to  disburse  the  Allowance  as  and  when  required 
hereunder.

(iii) Requirements of Tenant’s Agents. Each of Tenant’s Agents shall warrant that the portion of the Tenant Improvements 
for which it is responsible shall be free from any defects in workmanship and materials, that the materials and equipment used will be new and of good 
quality (unless expressly specified otherwise in the contract documents), and that the work will conform to the requirements of the contract documents. The 
foregoing warranties are in addition to any other warranties with respect to the work that may be required by the contract documents. Further, and without 
limiting  the  foregoing  warranties,  each  of  Tenant’s  Agents  shall  agree  to  be  responsible  for  the  replacement  or  repair,  without  additional  charge,  of  all 
defects in the work performed or furnished under its contract that become apparent during the one (1) year period following substantial completion of the 
Tenant Improvements. The correction of such work shall include, without additional charge, all additional expenses and damages incurred in connection 
with the removal or replacement of all or any part of the Tenant Improvements, and/or the Building and/or common areas that are damaged or disturbed as 
a result of the defective work or any replacement or repair work. All of the warranties and agreements described herein shall be contained in the Contract 
and each subcontract and shall be written such that they inure to the benefit of Landlord, Landlord and Tenant, as their respective interests may appear, and 
can be directly enforced by either. Tenant covenants to give to Landlord and/or Landlord any assignment or other assurances as may be necessary to affect 
such right of direct enforcement.

(c) Insurance Requirements.

(i) General Coverages. All of Tenant’s Agents shall carry worker’s compensation insurance covering all of their respective 
employees, and shall also carry public liability insurance, including property damage, all with limits, in form and with companies as are required to be 
carried by Landlord as set forth in the Lease (provided that the limits of liability to be carried by Tenant’s Agents and Contractor shall be in amounts as 
may be required by Landlord).

(ii) Special Coverages. During construction of any portion of the Tenant Improvements, Tenant shall carry “Builder’s All 
Risk”  insurance  in  an  amount  approved  by  Landlord  covering  the  construction  of  the  Tenant  Improvements  (at  Tenant’s  option,  Tenant  shall  cause 
Contractor to carry such Builder’s All Risk insurance), and such other insurance as Landlord or Landlord may reasonably require, it being understood and 
agreed that the Tenant Improvements shall be insured by Tenant pursuant to the Lease immediately upon completion thereof. Such insurance shall be in 
amounts and shall include such customary extended coverage endorsements as may be reasonably required by Landlord and/or Landlord, and shall be in 
form and with companies as are required to be carried by Tenant as set forth in the Lease. During construction of any portion of the Tenant Improvements, 
Tenant shall cause any architect and engineer to carry professional liability insurance with limits of not less than $2,000,000 per claim and in the annual 
aggregate covering professional services performed by the respective party, and such coverage must be maintained for the greatest period under which a 
claim may be properly asserted under the applicable statute of limitations or repose.

(iii) General Terms. Certificates for all insurance carried pursuant to this Section 3.2(c) shall be delivered to Landlord before 
the commencement of construction of the Tenant Improvements and before the Contractor’s equipment is moved onto the site. Tenant shall immediately 
notify  Landlord  in  the  event  any  policy  of  insurance  carried  by  Tenant  is  cancelled  or  the  coverage  materially  changed.  Tenant’s  Contractor  and 
subcontractors 

EXHIBIT 1.1.1-2
-8-

 
shall maintain all of the foregoing insurance coverage in force until the Tenant Improvements are fully completed and accepted by Landlord, except for any 
Products and Completed Operation Coverage insurance required by Landlord, which is to be maintained for ten (10) years following completion of the 
work  and  acceptance  by  Landlord  and  Tenant,  where  applicable.  All  policies  carried  under  this  Section  3.2(c)  (other  than  Workers’  Compensation 
coverage) shall insure Landlord, Landlord and Tenant, as their interests may appear. All insurance, except Workers’ Compensation, maintained by Tenant’s 
Agents  shall  preclude  subrogation  claims  by  the  insurer  against  anyone  insured  thereunder,  as  evidenced  by  an  endorsement  or  policy  excerpt.  Such 
insurance  shall  provide  that  it  is  primary  insurance  with  respect  to  the  Tenant  Improvements  and  that  any  other  insurance  maintained  by  Landlord  or 
Landlord is excess and noncontributing with the insurance required hereunder. The requirements for the foregoing insurance shall not derogate from the 
provisions for indemnification of Landlord by Tenant under the Lease or this Work Letter.

(d)  Governmental  Compliance.  The  Tenant  Improvements  shall  comply  in  all  respects  with  the  following:  (i)  the  Code  and  other

Landlord’s  failure  to  inspect  the  Tenant  Improvements  shall  in  no  event  constitute  a  waiver  of  any  of  Landlord’s  rights  hereunder  nor  shall  Landlord’s 
inspection of the Tenant Improvements constitute Landlord’s approval of the same. Should Landlord disapprove any portion of the Tenant Improvements, 
Landlord shall notify Tenant in writing of such disapproval and shall specify the items disapproved. Any defects or deviations in, and/or disapproval by 
Landlord of, the Tenant Improvements shall be rectified by Tenant at no expense to Landlord, provided however, that in the event Landlord determines that 
a defect or deviation exists or disapproves of any matter in connection with any portion of the Tenant Improvements and such defect, deviation or matter 
might adversely affect the mechanical, electrical, plumbing, heating, ventilating and air conditioning or life-safety systems of the Building or any portion of 
the Premises or the structure or exterior appearance of the Building, Landlord may take such action as Landlord deems necessary, at Tenant’s expense and 
without incurring any liability on Landlord’s part, to correct any such defect, deviation and/or matter, including, without limitation, causing the cessation of 
performance of the construction of the Tenant Improvements until such time as the defect, deviation and/or matter is corrected to Landlord’s satisfaction.

(f) Meetings. Tenant shall hold periodic meetings at a reasonable time with the Architect and the Contractor regarding the progress of 
the  preparation  of  the  Construction  Drawings  and  the  construction  of  the  Tenant  Improvements,  and  Landlord  shall  receive  prior  written  notice  of,  and 
Landlord  and/or  its  agents  (and  Landlord  and/or  its  agents)  shall  have  the  right  to  attend,  all  such  meetings,  and,  upon  Landlord’s  request,  certain  of 
Tenant’s Agents shall attend such meetings. In addition, minutes shall be taken at all such meetings, and Landlord and Landlord will be included in the 
distribution list for such minutes. One such meeting each month shall include the review of Contractor’s current request for payment.

5.2 Notice of Completion; Copy of Record Set of Plans. Within thirty (30) days after completion of construction of any portion of the Tenant 
Improvements, Tenant shall cause a Notice of Completion to be recorded in the office of the Recorder of San Francisco County in accordance with Section 
8182 of the California Civil Code or any successor statute, shall furnish a copy thereof to Landlord upon such recordation, and shall timely give all notices 
required pursuant to Section 8188 or 8190 of the California Civil Code or any successor statutes. If Tenant fails to do so, Landlord may execute and file 
such Notice of Completion and give such notices on behalf of Tenant as Tenant’s agent for such purpose, at Tenant’s sole cost and expense. Within thirty 
(30) days following the completion of construction of any portion of the Tenant Improvements, (i) Tenant shall cause the Architect and Contractor (A) to 
update the Approved Working Drawings as necessary to reflect all changes made to the Approved Working Drawings during the course of construction, (B) 
to certify to the best of their knowledge that the updated drawings are true and correct, which certification shall survive the expiration or termination of the 
Lease, and (C) to deliver to Landlord such updated drawings in accordance with Landlord’s then-current CAD Format Requirements, and (ii) Tenant shall

MISSION BAY REQUIREMENTS

1.  Environmental Covenant. The Project may contain hazardous materials in soils and in the ground water under the Project, and is subject to 
a deed restriction (Covenant and Environmental Restriction on Property) dated as of February 23, 2000, and recorded in the Official Records of the City 
and County of San Francisco, California (the “Official Records”) on March 21, 2000, as Document No. 2000-G748552 (the “Environmental Covenant”), 
which Environmental Covenant imposes certain covenants, conditions, and restrictions on usage of the Project. The foregoing statement is required by the 
Environmental Covenant and is not a declaration that a hazard exists. As required by Section 3.3 of the Environmental Covenant, Landlord hereby states as 
follows: “The land described herein may contain hazardous materials in soils and in the ground water under the property, and is subject to a deed restriction 
(Covenant and Restriction) dated as of February 23, 2000, and recorded on March 21, 2000, in the Official Records of San Francisco County, California, as 
Document No. G748552, which Covenant and Restriction imposes certain covenants, conditions, and restrictions on usage of the property described herein. 
This statement is not a declaration that a hazard exists.” The Environmental Covenant references and requires compliance with the provisions of the Risk 
Management Plan, Mission Bay Area, San Francisco, California, dated May 11, 1999 (as may be amended from time to time, the “RMP”). Tenant hereby 
acknowledges  receipt  of  a  copy  of  the  original  RMP,  and  hereby  covenants  (i)  to  comply  with  the  RMP  (to  the  extent  the  RMP  applies  to  Tenant’s 
activities),  (ii)  to  obligate  other  entities  with  which  Tenant  contracts  for  construction,  property  maintenance,  or  other  activities  that  may  disturb  soil  or 
groundwater to comply with the applicable provisions of the RMP, and (iii) to refrain (and to cause the entities with which it so contracts to refrain) from 
interfering with Landlord’s or other Occupant’s (with “Occupant” having the meaning ascribed in the Environmental Covenant) compliance with the RMP. 
Additionally, in all future leases, licenses, permits, or other agreements between Tenant and another entity which authorizes such entity to undertake or to 
engage in activities that are subject to one or more requirements set forth in the RMP, Tenant will provide a copy of the RMP or its relevant provisions prior 
to execution of such agreements and ensure that such agreements contain covenants that (i) such entity will comply with the RMP (to the extent the RMP 
applies to the entity’s activities); (ii) such entity will obligate other entities with which it contracts for construction, property maintenance or other activities 
which  may  disturb  soil  or  groundwater  to  comply  with  the  applicable  provisions  of  the  RMP;  and  (iii)  such  entity  (and  the  entities  with  which  it  so 
contracts) will refrain from interfering with Landlord’s, Tenant’s, or other Occupants’ compliance with the RMP.

2.  Special Tax Acknowledgment. In accordance with Section 53341.5 of the California Government Code, Tenant previously has delivered to 
Landlord  acknowledgments,  duly  executed  by  Tenant,  confirming  that  Tenant  has  been  advised  of  the  terms  and  conditions  of  the  “CFDs”  (as  defined 
below), including that the Project is subject to the “CFD Assessments” (as defined below). As used herein, (a) “CFDs” shall mean, collectively, (i) the

School Facilities) (the “Public School CFD”) (established to pay a portion of the costs of acquiring and/or constructing public school facilities), and (b) 
“CFD Assessments”  shall  mean  the  special  taxes  (i)  to  be  levied  on  the  Project  and  other  property  in  Mission  Bay  in  accordance  with  the  terms  and

Project  Labor  Agreement.  Tenant  has  been  informed  by  Landlord  of  the  following:  (a)  Perini  Corporation,  CDC  and  its  parent, 
subsidiaries  and  successor  developers  in  which  it  holds  a  majority  interest  (collectively,  “CDC Parties”),  the  San  Francisco  Building  and  Construction 
Trades Council, AFL-CIO (“Council”), and certain affiliated local unions originally entered into a certain Mission Bay Project Agreement (the “Original 
Project Labor Agreement”) for the Mission Bay project on October 8, 1990, pursuant to which (i) CDC Parties 

EXHIBIT 4.4.3
-1-

 
agreed,  to  the  fullest  extent  possible,  to  award  all  construction  contracts  in  Mission  Bay  for  “Covered  Work”  (as  defined  in  the  Original  Project  Labor 
Agreement)  to  unionized  construction  firms;  and  (b)  CDC  and  the  individual  members  of  the  Council  entered  into  an  Addendum  to  Agreement 
(“Addendum”)  that  amended  certain  terms  of  the  Original  Project  Labor  Agreement  (the  Original  Project  Labor  Agreement,  as  amended  by  the 
Addendum, shall be referred to as the “Project Labor Agreement”), pursuant to which CDC agreed that CDC would require, as a condition of any sale, 
conveyance,  ground  lease,  or  donation  of  real  property  covered  by  the  Project  Labor  Agreement  (“Covered Property”),  that  any  and  all  successors  in 
interest  and/or  assignees,  buyers,  ground  lessees,  or  donees  (any  of  the  foregoing,  a  “Covered  Successor”)  of  Covered  Property  shall  require  any 
contractors  to  which  the  Covered  Successor  contracts  work  that  is  covered  by  the  Project  Labor  Agreement  to  sign  and  become  a  party  to  a  successor 
project  labor  agreement  (a  “Successor Project Labor Agreement”,  the  form  of  which  is  attached  hereto  as  Schedule 1 to  this  Exhibit  4.4.3).  Tenant 
acknowledges that the Project is Covered Property, that Landlord is a Covered Successor, and that Landlord has agreed to require any contractors to which 
Landlord contracts work which is Covered Work to sign and become a party to a Successor Project Labor Agreement. Accordingly, Tenant hereby agrees 
that Tenant shall require any contractors to which Tenant or any of its contractors contract work which is Covered Work to execute and deliver a Successor 
Project Labor Agreement. If Tenant acts as a contractor, Tenant shall be required to sign a Successor Project Labor Agreement as project contractor. Tenant 
will cause its general contractor to execute a Successor Project Labor Agreement prior to the commencement of any construction work on the Project and 
shall deliver an executed original of each Successor Project Labor Agreement to Landlord. Following Landlord’s receipt of such executed original of the 
Successor Project Labor Agreement, Landlord shall use commercially reasonable efforts to obtain full execution of the Successor Project Labor Agreement 
by  the  union  signatories,  but  Tenant  acknowledges  that  Landlord  shall  have  no  liability  whatsoever  if  full  execution  of  the  Successor  Project  Labor 
Agreement is not obtained.

4.  First  Source  Hiring  Program.  Tenant  has  been  informed  by  Landlord  that  there  is  a  City-wide  “First  Source  Hiring  Program”  (“ FSHP”) 
(adopted by the City and County of San Francisco on August 10, 1998, Ordinance No. 264-98). Tenant hereby acknowledges that its activities with respect 
to the Project are or may be subject to the FSHP. Accordingly, Tenant shall comply with any provisions of the FSHP that are applicable to the Premises or 
any construction in, or use or development of, the Premises by Tenant.

5.  Non-Discrimination.  Without  limiting  the  generality  of  any  other  provision  of  this  Lease,  there  shall  be  no  discrimination  against,  or 
segregation  of,  any  person  or  group  of  persons  or  any  employee  or  applicant  for  employment  on  account  of  race,  color,  creed,  religion,  sex,  marital  or 
domestic partner status, familial status, national origin, ancestry, lawful source of income (as defined in Section 3304 of the San Francisco Police Code), 
gender identity, sexual orientation, age, or disability (including, without limitation, HIV/AIDS status) in the sale, lease, sublease, transfer, use, occupancy, 
tenure, or enjoyment of any part of the Project, nor shall Tenant or any person claiming under or through Tenant, establish or permit any such practice or 
practices of discrimination or segregation with reference to the selection, location, number, use, or occupancy of tenants, lessees, subtenants, sublessees, or 
vendees in any part of the Project. All deeds, leases, subleases, or contracts concerning the Project shall contain the non-discrimination and non-segregation 
clauses specified for each type of document in Section 33436 of the California Health and Safety Code.

6.  Tax Exempt Entities. Tenant acknowledges that it has received and reviewed that certain Grant Deed dated May 19, 2014, executed and 
acknowledged on behalf of FOCIL-MB, LLC, and Landlord, recorded in the Official Records on May 23, 2014, as Document No. 2014-J886903-00 (the 
“Grant Deed”), and further that this Lease and Tenant are subject and subordinate to, and Tenant shall not violate, the covenants contained in such Grant 
Deed.  Such  Grant  Deed  contains  certain  covenants  by  Landlord  regarding  payments  of  taxes  (or  payments  in  lieu  of  taxes)  if  (a)  there  is  any  sale, 
assignment, conveyance, lease, sublease, or other alienation of any portion of the Project to an entity that is or could be exempt from property taxation (a 
“Tax Exempt Entity”), or (b) there is a grant to a Tax Exempt Entity of occupancy rights (such as under a space lease) where, as the result of such grant, 
all or any portion of any improvements on all or any portion of the Project would or could be exempt from property taxation. Accordingly, Tenant shall not 
Transfer the Premises, or any portion thereof, or sublease space in, or otherwise grant any occupancy rights, in the Premises to any Tax Exempt Entity 
without first: (a) obtaining from such Tax Exempt Entity a binding contractual commitment, in form and substance reasonably satisfactory to, and for the 
benefit of, the Successor Agency to the Redevelopment Agency (the “Successor Agency”) and the City and County of San Francisco (collectively, “City 
and County”), obligating such entity to make a payment in lieu of taxes (“PILOT Agreement”) equal to the full amount of the property taxes that would 
have been assessed against the Premises notwithstanding 

EXHIBIT 4.4.3
-2-

 
such occupancy by a Tax Exempt Entity; or (b) entering into a binding PILOT Agreement, in form and substance reasonably satisfactory to, and for the 
benefit of, the Successor Agency and the City and County, requiring the full payment of property taxes (or a payment in lieu thereof in an amount equal to 
the property taxes) that would have been assessed against the Premises notwithstanding such occupancy by such Tax Exempt Entity, or (c) obtaining the 
written consent of the Successor Agency and the City and County, in their respective sole discretion. Tenant hereby agrees not to request that Landlord 
request an adjustment to the “Base Year Value” (as defined below) for the “South Plan Area” (as defined in the OPA), or any portion thereof, as a result of 
any Transfer permitted under this Lease to a Tax Exempt Entity. For purposes hereof, (i) the term “Base Year Value” means the aggregate assessed value of 
property within the South Plan Area on the assessment roll last equalized prior to the effective date of the ordinance adopting the Redevelopment Plan, and 
(ii) the term “last equalized” has the meaning set forth in Section 2052 of the California Revenue and Tax Code.

7.  Mitigation  Measures.  Tenant  has  been  informed  by  Landlord  that  the  Project  (along  with  other  property)  is  subject  to  the  Mitigation 
Monitoring and Reporting Program for the Mission Bay South Plan Area (including, but not limited to, the Mission Bay South CEQA Mitigation Measures 
described in Attachment L to the Mission Bay South Owner Participation Agreement between the Redevelopment Agency and CDC dated November 16, 
1998,  and  recorded  in  the  Official  Records  on  December  3,  1998,  as  Document  No.  98-G477258).  Tenant  shall  comply  with  the  following  mitigation 
measures (and with any other mitigation measures that Landlord reasonably determines are applicable to Tenant’s operations in the Premises):

(a)

Mitigation  Measure  L01  (Biohazardous  Materials  Handling  Guidelines):  Require  businesses  that  handle  biohazardous 
materials and do not receive federal funding to certify that they follow the guidelines published by the National Research Council and the U.S. 
Department of Health and Human Services Public Health Service, National Institutes of Health, and Centers for Disease Control as set forth in 
Biosafety in Microbiological and Biomedical Laboratories, Guidelines for Research Involving Recombinant DNA Molecules (NIH Guidelines), 
and Guide for the Care and Use of Laboratory Animals, or their successors, as applicable.

(b)

Mitigation Measure L02 (Use of HEPA Filters): Require businesses handling biohazardous materials to certify that they use 
high efficiency particulate air (HEPA) filters or substantially equivalent devices on all exhaust from Biosafety Level 3 laboratories unless they 
demonstrate  that  exhaust  from  the  Biosafety  Level  3  laboratories  would  not  pose  a  substantial  health  and  safety  hazards  to  the  public  or  the 
environment. Require such businesses to certify that they inspect or monitor the filters regularly to ensure proper functioning.

(c)

Mitigation  Measure  L03  (Handling  of  Biohazardous  Materials):  Require  businesses  handling  biohazardous  materials  to 
certify that they do not handle or use biohazardous materials requiring Biosafety Level 4 containment (i.e., dangerous or exotic materials that 
pose high risks of life-threatening diseases or aerosol-transmitted infections, or unknown risks of transmitting in the Project Area).

8.  Declaration  of  Tax  Appeal  Waiver  Agreement.  Tenant  acknowledges  that  it  has  received  and  reviewed  a  certain  Declaration  of  Tax 
Appeal  Waiver  Agreement  dated  May  23,  2014,  executed  and  acknowledged  on  behalf  of  FOCIL-MB,  LLC,  and  Landlord,  recorded  in  the  Official 
Records on May 23, 2014, as Document No. 14-J886906 (“Declaration of Tax Appeal Waiver Agreement”), and further that this Lease and Tenant are 
subject and subordinate to, and Tenant shall not violate, the covenants contained in such Declaration of Tax Appeal Waiver Agreement. Such Declaration of 
Tax  Appeal  Waiver  Agreement  contains  certain  covenants  by  Landlord  to  not  (and  waivers  of  any  rights  to)  take  any  action  or  seek  to  take  any  action 
(including filing any appeal, contest, commencing any legal action or otherwise challenging or disputing in any way) that would result in a reduction of the 
assessed value of the Project for property tax purposes below a “Minimum Amount” (as defined in the Declaration of Tax Appeal Waiver Agreement as 
the sum of (i) $95,000,000.00 plus (ii) the actual construction costs for the Project, provided, however, that the Minimum Amount shall increase on the 
anniversary of the Completion of Construction (as defined therein) and annually thereafter by 2%). In connection with the foregoing, and notwithstanding 
the terms and conditions of Article 4 of this Lease, (a) Tenant shall not have the right to require Landlord to seek any reduction in Tax Expenses below the 
Minimum  Amount,  and  (b)  notwithstanding  anything  to  the  contrary  set  forth  in  this  Lease,  only  Landlord  may  institute  proceedings  to  reduce  Tax 
Expenses and the filing of any such proceeding by Tenant without Landlord’s consent shall constitute an Event of Default by Tenant under this Lease.

PROJECT AGREEMENT

This  Project  Agreement 

(“Agreement”) 

is 

entered 

into 

this  ______  day  of  _____________,  200_  by 

and 

among 

_________________________________  (hereinafter  referred  to  as  the  “Project  Contractor”),  and  the  San  Francisco  Building  and  Construction  Trades 

Council, AFL-CIO; and affiliated Local Unions whose names are subscribed hereto and who have, through their duly authorized officers, executed this 

Agreement (hereinafter collectively referred to as the “Union” or the “Unions”). The term Contractor as used in this Agreement includes all contractors and 

subcontractors of whatever tier. Contractor agrees to comply with the collective bargaining agreements listed in Schedule A for the purposes of the Covered 

Work  only,  and  any  obligation  incurred  under  Schedule  A  agreements  shall  expire  with  the  termination  of  this  Agreement.  Where  specific  reference  to 

________________ only is intended, the term Project Contractor is used. This project is being constructed pursuant to an Owner’s Participation Agreement 

(“Owner OPA”) for Mission Bay _______________ originally between the Redevelopment Agency of the City and County of San Francisco and Catellus 

Development  Corporation  (“Catellus”)  and  subsequently  transferred  in  part  to  _____________________  (the  “Owner”).  The  project  area  is  generally 

bound by ________________________________________________________.

Catellus  and  the  Unions  entered  into  the  Mission  Bay  Project  Agreement  (“Original  PLA”)  for  the  entire  Mission  Bay  project  on  October  8, 

1990. The Original PLA was amended by an Addendum to Agreement effective __________________ 2003 (“Addendum”), which among other things, 

requires the execution of this Agreement by the Project Contractor when Catellus sells, conveys, ground leases or donates to a third party any real property 

covered by the Original PLA, subject to the terms and conditions of the Addendum.

ARTICLE I.  PURPOSE

The construction at the Owner’s project will require substantial numbers of employees from construction and other supporting crafts. The orderly 

and uninterrupted construction of the work at the Mission Bay project and the Owner’s project are of significant interest to the parties to this Agreement.

It  is  the  purpose  of  this  Agreement  to  ensure  that  all  work  covered  by  this  Agreement  proceeds  efficiently,  economically,  and  with  due 

consideration for the protection of labor standards, wages, and working conditions.

Consistent  with  the  implementation  of  the  programs  described  in  the  Mission  Bay  Affirmative  Action  and  Economic  Development  Plan 

(“MBAAWEDP”),  Project  Contractor  will,  to  the  fullest  extent  possible,  award  all  construction  contracts  to  unionized  construction  firms.  Project 

Contractor further commits that all construction work under its jurisdiction shall be at prevailing wages, fringes and conditions for all trades and crafts 

pursuant to the appropriate contract identified on Schedule A. Project Contractor will use good-faith efforts to maximize MBE, WBE and LBE contracts 

with union firms. Should it be determined that Minority Business Enterprise/Women Owned Business Enterprise; (MBE/WBE) goals for .this project are 

not being reached a a result of this Agreement, the affected crafts, San Francisco Building Trades Council and Project Contractor will meet and confer to 

arrive at a resolution which allows for MBE/WBE goal attainment.

The  parties  to  this  Agreement  have  agreed  and  do  establish  and  put  into  practice  effective  and  binding  methods  for  the  settlement  of  all 

misunderstandings, disputes, or grievances that may arise between or among the parties to this Agreement. To accomplish the purpose that the Contractor 

be assured of complete continuity of operation and that labor-management peace be maintained, the Unions agree not to engage in any strike, picketing, 

work stoppage, slowdown, sympathy action or any other disruptive activities directed to or in connection with Covered Work, and the Contractors agree not 

to engage in any lockout.

ARTICLE II. EFFECT OF OTHER AGREEMENTS

The provisions of this Agreement, including the local collective bargaining agreements listed on Schedule A, shall apply to Project Contractor’s 

construction and the Owner’s project, notwithstanding the provisions of local and/or national union agreements which may conflict or differ with the terms 

of this Agreement.  Where a subject is covered by the provisions of this Agreement is also covered by a collective bargaining agreement which is listed on 

Schedule A, the provisions of this Agreement shall prevail. Where a subject is covered by the provisions of a collective bargaining agreement identified in 

Schedule A and not covered by this Agreement, the provisions of the appropriate collective bargaining agreement identified on Schedule A shall prevail. 

Further, the parties are bound by the MBAAEDP which is incorporated in its entirety in this document as though set forth herein. This Agreement is not a 

collateral agreement within the meaning of Section 56.3(c) and 56.11 of the San Francisco Administrative Code.

ARTICLE III.

ARTICLE V.  MANAGEMENT'S RIGHTS

The Contractors retain full and exclusive authority for the management of its operations. Except as expressly limited by other provisions of this 

Agreement and the appropriate collective bargaining agreement listed on Schedule A, the Contractor retains the right to direct the working force, including 

the hiring, promotion, transfer, discipline or discharge of employees; the selection of foremen; the assignment and scheduling of work; and, the requirement 

of overtime work and the determination of when it shall be worked. No rules, customs, or practices which limit or restrict productivity, efficiency or the 

individual and/or joint working efforts of employees shall be permitted or observed. The Contractor may utilize any methods or techniques of construction.

Except  as  otherwise  stated  in  the  appropriate  collective  bargaining  agreement  listed  on  Schedule  A,  there  shall  be  no  limitation  or  restriction 

upon  the  Contractor’s  choice  of  materials  or  design,  nor,  regardless  of  source  or  location,  upon  the  full  use  and  installation  of  equipment,  machinery, 

package units, precast, prefabricated, prefinished or preassembled materials, tools, or other labor saving devices.  The Contractor may without restriction 

install or otherwise use materials, supplies or equipment regardless of their source.  The on-site installation of application of such items shall be performed 

by the craft customarily having jurisdiction over such work under the applicable collective bargaining agreement listed on Schedule A; provided, however, 

it is recognized that other personnel having special talents or qualifications may participate in the installation, checkout or testing of specialized or unusual 

equipment or facilities.

Exhibit A – 6

EXHIBIT 4.4.3

Except  as  otherwise  stated  in  the  appropriate  collective  bargaining  agreement  listed  on  Schedule  A,  it  is  recognized  that  the  use  of  new 

technology, equipment, machinery, tools and/or labor savings devices and methods of performing work will be initiated by the Contractor from time to time 

during  the  project.    The  Union  agrees  that  it  will  not  in  any  way  restrict  the  implementation  of  such  new  devices  or  work  methods.    If  there  is  any 

disagreement between the Contractor and the Union concerning the manner or implementation of such device or method of work, the implementation shall 

proceed as directed by the Contractor, and the Union shall have the right to arbitrate the dispute as set forth in Article VIII of this Agreement.

The  failure  of  the  Contractor  to  exercise  rights  herein  reserved  to  it  or  the  exercise  of  those  rights  in  a  particular  way  shall  not  be  deemed  a 

waiver of said rights or of the Contractor’s right to exercise said rights in some other manner not in conflict with the terms of this Agreement.

ARTICLE VI. 

UNION REPRESENTATION

Authorized representatives of the Union shall have access to the Covered Work provided they do not interfere with the work of employees and 

further provided that such representatives fully comply with the posted visitor and security and safety rules of the Covered Work.

The Union shall have the right to designate working journey workers as stewards. The Union shall, in writing, notify the Contractor as to the 

identity of the designated steward prior to the assumption of his/her duties as a steward. In addition to his/her work as an employee, the steward shall have 

the  right  to  receive,  but  not  solicit,  complaints  or  grievances  and  to  discuss  and  assist  in  the  adjustment  of  the  same  with  the  employee’s  appropriate 

supervisor.  The  Contractor  will  not  discriminate  against  a  steward  in  the  proper  performance  of  his/her  Union  duties  provided  that  such  duties  do  not 

interfere with his/her regular work or with the work of other employees. Stewards shall receive the regular rate of pay for their respective craft. There will 

be no non-working stewards. The steward shall not have the right to determine when overtime shall be worked or who shall work overtime, or to interfere 

with any of the supervisory functions of the Contractor.

Exhibit A – 7

EXHIBIT 4.4.3
-10-

 
 
The Contractor agrees to notify the appropriate Union twenty-four (24) hours prior to the layoff of a steward, except in the case of discipline or 

discharge for a cause.  If a steward is protected against such layoff by the provision of any of the collective bargaining agreements listed on Schedule A, 

such protection shall be recognized to the extent that the steward possesses the necessary qualifications to perform the work remaining.  In any case in 

which  a  steward  is  discharged  or  disciplined  for  cause  the  appropriate  Union  shall  be  notified  immediately  by  the  Contractor.    For  the  purpose  of  this 

provision,  “cause”  for  discharge  shall  mean  incompetence,  unexcused  absenteeism,  disobedience  of  orders,  unsatisfactory  performance  of  duties  and 

violation of posted project work rules.

On  work  where  Catellus’  or  Owner’s  personnel  may  be  working  in  close  proximity  of  the  construction  activities,  the  Union  agrees  that  its 

representatives,  stewards  and  individual  workers  will  not  interfere  with  Catellus’  or  Owner’s  personnel  or  with  the  work  which  is  being  performed  by 

Catellus’  or  Owner’s  personnel.  This  is  not  to  be  construed  to  mean  that  Catellus’  or  Owner’s  personnel  may  perform  work  covered  by  the  collective 

bargaining agreements listed on Schedule A.

ARTICLE VII  WORK STOPPAGES AND LOCKOUTS

During the term of this Agreement, there shall be no strikes, picketing, work stoppages, slowdowns, sympathy actions or any other disruptive 

activities directed at or in connection with Covered Work for any reason by the Union or by any employee, and there shall be no lockout by the Contractor.

Exhibit A – 8

EXHIBIT 4.4.3
-11-

 
 
Failure of any Union or employee to cross any picket line established at the site of Covered Work is a violation of this Article.

The  Union  shall  not  sanction,  aid  or  abet,  encourage  or  continue  any  work  stoppage,  slowdown,  sympathy  action,  strike,  picketing  or  other 

disruptive  activity  at  the  site  of  Covered  Work  and  shall  undertake  all  possible  means  to  prevent  or  to  terminate  any  such  activity.  No  employee  shall 

engage in activities which violate this Article.  Any employee who participates in or encourages any activities which interfere with the normal operations of 

the  Covered  Work  shall  be  subject  to  disciplinary  action,  including  discharge.    The  Union  shall  not  be  liable  for  acts  of  employees  for  which  it  has  no 

responsibility.

In lieu of or in addition to any other action at law or equity, any party, including the Project Contractor, who the parties agree is a beneficiary of 

this Agreement and specifically this Article with full right of participation in any action under this Article, may institute the following procedure when a 

breach of paragraphs 1, 2, and/or 3 of this Article is alleged:

(a)  The party invoking this procedure shall notify Gerald Mckay or John Kagel who the parties agree shall be the permanent Arbitrator under 

this  procedure.  In  the  event  that  the  permanent  Arbitrator  is  unavailable  at  any  time,  he  shall  appoint  his  alternate.  Notice  to  the 

Arbitrator shall be by the most expeditious means available, with notice by telegram to the party alleged to be in violation and the 

involved International Union President.

(b)  Upon receipt of said notice, the Arbitrator named above or his alternate shall set and hold a hearing within twenty-four (24) hours if it is 

contended that the violation still exists.

Exhibit A – 9

EXHIBIT 4.4.3
-12-

 
 
(c)  The Arbitrator shall notify the parties by telegram of the place and time he has chosen for this hearing. Said hearing shall be completed in 

one session.  A failure of any party to parties to attend said hearing shall not delay the hearing of evidence or issuance of an award by 

the Arbitrator.

(d)  The sole issue at the hearing shall be whether or not a violation of paragraphs 1, 2 and/or 3 of this Article has, in fact, occurred and the 

Arbitrator  shall  have  no  authority  to  consider  any  matter  in  justification,  explanation  or  mitigation  of  such  violation  or  to  award 

damages. Any issue concerning damages is reserved for court proceedings, if any.  The award shall be issued in writing within three 

(3) hours after the close of the hearing and may be issued without an opinion.  If any party desires an opinion, one shall be issued 

within  fifteen  (15)  days,  but  its  issuance  shall  not  delay  compliance  with,  or  enforcement  of  the  Award.    The  Arbitrator  may  order 

cessation  of  the  violation  of  this  Article  and  other  appropriate  relief,  and  such  Award  shall  be  served  on  all  parties  by  hand  or 

registered mail upon issuance.

(e)  Such Award may be enforced by any court of competent jurisdiction upon the filing of this Agreement and all other relevant documents 

referred to hereinabove in the following manner.  Telegraphic notice of the filing of such enforcement proceedings shall be given to the 

other party.  In the proceeding to obtain an temporary order enforcing the Arbitrator’s Award as issued under paragraph 4(d) of this 

Article, all parties waive the right to a hearing and agree that such proceedings may be ex parte.  Such Agreement does not waive any 

party’s right to participate in a hearing for a final order of enforcement.  The court’s order or orders enforcing the Arbitrator’s Award 

shall be served on all parties by hand or by delivery to their last known address or by registered mail.

Exhibit A – 10

EXHIBIT 4.4.3
-13-

 
 
(f)  Any  rights  created  by  statute  or  law  governing  arbitration  proceedings  inconsistent  with  the  above  procedure  or  which  interfere  with  

compliance therewith are hereby waived by the parties to whom they accrue.

(g)  The fees and expenses of the Arbitrator shall be divided equally between the moving parties and the party or parties respondent.

ARTICLE VIII   PROJECT COORDINATION COMMITTEE

The parties agree to form a committee comprised of representatives for the Building Trades Council, affected local union and Project Contractor, 

to meet and discuss issues which may arise from time to time regarding the interpretation, application and enforcement of this Agreement.

In  the  event  a  dispute  arises  between  or  among  the  parties  thereto  which  cannot  be  resolved  by  the  committee  described  in  the  preceding 

paragraph, then the dispute shall be referred to arbitration as described in Article VII with mutually agreed-upon extensions to time limits set forth therein, 

as may be required.

ARTICLE IX  WORK ASSIGNMENTS AND JURISDICTION DISPUTES

Work shall be assigned by the Contractor.  There shall be no strikes, picketing, work stoppage, sympathy actions, slowdowns or other disruptive 

activity arising out of any jurisdictional dispute directed at or in connection with Covered Work during the term of this Agreement.

Except  as  provided  below,  all  jurisdictional  disputes  will  be  settled  in  accordance  with  the  procedural  roles  and  decisions  of  the  Plan  for 

Settlement of Jurisdictional Disputes in the Construction Industry and shall be binding upon the Contractor and the Unions.

Exhibit A – 11

EXHIBIT 4.4.3
-14-

 
 
Where a jurisdictional dispute involves any Union not a party to the Plan for Settlement of Jurisdictional Disputes in the Construction Industry 

and is not resolved among the Unions and the site representative of the affected Contractor, it shall be referred for resolution to the International Unions 

with which the disputed Unions are affiliated.  The International Unions shall hereafter meet with the representative of the affected Contractor to reach a 

joint resolution of the disputes.  For purposes of all disputes referred to the International Unions shall hereafter meet with the representative of the affected 

Contractor to reach a joint resolution of the disputes.  For purposes of all disputes referred to the International Unions, the Project Contractor shall be a 

party in interest. The resolution of the dispute shall be reduced to writing, signed by representatives of the Local and/or International Unions and a copy

Tenant  shall  faithfully  observe  and  comply  with  the  following  Rules  and  Regulations.  Landlord  shall  not  be  responsible  to  Tenant  for  the 
nonperformance of any of said Rules and Regulations by or otherwise with respect to the acts or omissions of any other tenants or occupants of the Project. 
In the event of any conflict between the Rules and Regulations and the other provisions of this Lease, the latter shall control. 

1.  Tenant shall not alter any lock or install any new or additional locks or bolts on any doors or windows of the Premises without obtaining 
Landlord’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed. If Tenant shall affix additional locks on doors then 
Tenant shall furnish Landlord with copies of keys or pass cards or similar devices for said locks. Tenant shall bear the cost of any lock changes or repairs 
required by Tenant. Two keys will be furnished by Landlord for the Premises, and any additional keys required by Tenant must be obtained from Landlord 
at a reasonable cost to be established by Landlord. Upon the termination of this Lease, Tenant shall restore to Landlord all keys of stores, offices, and toilet 
rooms, either furnished to, or otherwise procured by, Tenant and in the event of the loss of keys so furnished, Tenant shall pay to Landlord the cost of 
replacing  same  or  of  changing  the  lock  or  locks  opened  by  such  lost  key  if  Landlord  shall  deem  it  necessary  to  make  such  changes.  Notwithstanding 
anything to the contrary contained in the foregoing, Tenant may control entry to Tenant designated laboratory facilities within its Premises.

2.  All doors opening to public corridors shall be kept closed at all times except for normal ingress and egress to the Premises.

3.  Landlord reserves the right to close and keep locked all entrance and exit doors of the Building during such hours as are customary for the

Premises if it is after the normal hours of business for the Building. Any tenant, its employees, agents or any other persons entering or leaving the Building 
at any time when it is so locked, or any time when it is considered to be after normal business hours for the Building, may be required to sign the Building 
register. Access to the Building may be refused unless the person seeking access has proper identification or has a previously arranged pass for access to the 
Building. Landlord will furnish passes to persons for whom Tenant requests same in writing. Tenant shall be responsible for all persons for whom Tenant 
requests passes and shall be liable to Landlord for all acts of such persons. Landlord and its agents shall in no case be liable for damages for any error with 
regard to the admission to or exclusion from the Building of any person. In case of invasion, mob, riot, public excitement, or other commotion, Landlord 
reserves  the  right  to  prevent  access  to  the  Building  or  the  Project  during  the  continuance  thereof  by  any  means  it  deems  appropriate  for  the  safety  and 
protection of life and property.
