Risk Factor Summary

An investment in the Company involves risks. You should carefully read this entire report and consider the uncertainties and risks discussed in the

“Risk Factors” section in Part I, Item 1A of this report, which may adversely affect our business, financial condition, or results of operations, along with the
other information included in our other filings with the Securities and Exchange Commission, before deciding to invest in the Company. A summary of the
principal factors that make an investment in the Company speculative or risky is set forth below.

● The ongoing novel coronavirus (“COVID-19”) pandemic could create challenges in all aspects of our business, including, without limitation,

delays, stoppages, difficulties, and increased expenses with respect to our and our partners’ development, regulatory processes, and supply chains,
negatively impact our ability to access the capital or credit markets to finance our operations, or have the effect of heightening many of the risks
described below or in the “Risk Factors” section in Part I, Item 1A of this report.

● We have incurred losses since our inception, expect to continue to incur losses, and may never be profitable.

● We may need to raise additional capital in the future. If we are unable to raise capital when needed, we may need to adjust our operations.

● Our success depends upon our ability to advance our product candidates through the various stages of development, especially through the clinical
trial process, to receive and maintain regulatory approval for the commercial sale of our product candidates, and to successfully commercialize
any approved products. The development process and related regulatory processes are complex and uncertain, may be lengthy and expensive, and
require, among other things, an indication that our products and product candidates are safe and effective. For example, applicable regulatory
agencies could refuse to approve, or impose restrictions or warnings on, our product candidates, require us to conduct additional studies or adopt
study designs that differ from our planned development strategies, suspend or terminate our clinical trials, or take other actions that could
materially impact the cost, timing, and success of our planned development strategies.

● We rely heavily upon third parties, including development partners, contractors, contract research organizations, and third-party suppliers,

manufacturers, and distributors, for many important stages of our product candidate development and in the commercialization of certain of our
products and product candidates. Our failure to maintain these relationships, the failure of any such third party to perform its obligations under
agreements with us, or the failure of such a relationship to meet our expectations could have a material adverse impact on our business, financial
condition, and results of operations.

● If we fail to obtain additional financing or acceptable partnership arrangements, we may be unable to complete the development and

commercialization of our products and product candidates or continue operations.

● The commercial viability of any approved product could be compromised if the product is less effective than expected, causes undesirable side

effects that were not previously identified, or fails to achieve market acceptance by physicians, patients, third-party payors, health authorities, and
others.

● There can be no assurance that our or our partners’ commercialization efforts, methods, and strategies for our products or technologies will

succeed, and our future revenue generation is uncertain.

● We expect to continue expanding our development and regulatory capabilities and implementing sales, marketing, and distribution capabilities,

and as a result, we may encounter difficulties managing our growth, which could disrupt our operations.

● We face intense competition, and if we are unable to compete effectively, the demand for our products may be reduced. In addition, developments

by others may render our products, product candidates, or technologies obsolete or noncompetitive.

● We are subject to various laws and regulations related to our products and product candidates, and if we or our employees, consultants, or partners
do not comply with these laws and regulations, we could face substantial penalties and our reputation could be harmed. In addition, we and our
partners may be subject to new legislation, regulatory proposals, and healthcare payor initiatives that may increase our costs of compliance and
adversely affect our or our partners’ ability to market our products, obtain collaborators, and raise capital.

● If we fail to adequately protect or enforce our intellectual property rights or secure rights to patents of others, the value of those rights would
diminish. Legal proceedings to protect or enforce our patents, the patents of our partners, or our other intellectual property rights could be
expensive, time consuming, and unsuccessful.

● We face an inherent risk of liability in the event that the use or misuse of our products or product candidates results in personal injury or death, and

our product liability insurance coverage may be insufficient.

● We face risks related to our government-funded programs and are subject to various U.S. Government contract requirements, which typically

contain a number of extraordinary provisions that would not typically be found in commercial contracts and which may create a disadvantage and
additional risks to us as compared to competitors that do not rely on U.S. Government contracts.

● If we fail to reach milestones or to make annual minimum payments or otherwise breach our obligations under our license agreements, our

licensors may terminate our agreements with them and seek additional remedies.

● Our Credit Agreement contains conditions and restrictions that limit our flexibility in operating our business. We may be required to make a

prepayment or repay our outstanding indebtedness under the Credit Agreement earlier than we expect if a prepayment event or an event of default
occurs, including a material adverse change with respect to us, which could have a material adverse effect on our business.

● International expansion of our business exposes us to business, regulatory, political, operational, financial, and economic risks. For example, our
actual or perceived failure to comply with European governmental regulations and other obligations related to privacy, data protection, and
information security could harm our business. In addition, the United Kingdom’s withdrawal from the European Union could result in increased
regulatory and legal complexity, which may make it more difficult for us to do business in Europe and impose additional challenges in securing
regulatory approval of our product candidates in Europe.

● If our facilities incur damage or power is lost for a significant length of time, our business will suffer.

● A significant disruption in our information technology systems or a cybersecurity breach could adversely affect our business.

● Our existing principal stockholders hold a substantial amount of our common stock and may be able to influence significant corporate decisions,

which may conflict with the interests of other stockholders.

● Our stock price has been, and is likely to continue to be, highly volatile, which could cause the value of an investment in our common stock to

decline significantly.

● Natural disasters, epidemic or pandemic disease outbreaks, trade wars, political unrest, or other events could disrupt our business or operations or

those of our development partners, manufacturers, regulators, or third parties with whom we conduct business now or in the future.

● We are subject to legal proceedings, which could harm our reputation or result in other losses or unexpected expenditure of time and resources.

● If we fail to retain our existing key personnel or fail to attract and retain additional key personnel, the development of our product candidates, the

commercialization of our products, and the related expansion of our business will be delayed or stopped.

ITEM 1.         BUSINESS

Our Business

PART I

We are a commercial-stage biotechnology company that discovers novel, oral, small-molecule medicines. We focus on oral treatments for rare

diseases in which significant unmet medical needs exist and an enzyme plays the key role in the biological pathway of the disease. We integrate the
disciplines of biology, crystallography, medicinal chemistry and computer modeling to discover and develop small molecule pharmaceuticals through the
process known as structure-guided drug design. Structure-guided drug design is a drug discovery approach by which we design synthetic compounds from
detailed structural knowledge of the active sites of enzyme targets associated with particular diseases. We use X-ray crystallography, computer modeling of
molecular structures and advanced chemistry techniques to focus on the three-dimensional molecular structure and active site characteristics of the
enzymes that control cellular biology. Enzymes are proteins that act as catalysts for many vital biological reactions. Our goal generally is to design a
compound that will fit in the active site of an enzyme and thereby prevent its catalytic activity. Molecules from our discovery efforts that are commercially
available or that are in active development are summarized in the table below and are discussed in further detail under “Products and Product Candidates”

Business Strategy

Our business strategy is to create stockholder value both by focusing our discovery and development efforts on oral drugs for rare diseases for which

a significant unmet medical need exists and by efficiently commercializing these drugs in the United States and certain other regions upon regulatory
approval. By focusing on rare disease markets, we believe that we can more effectively control the costs of, and our strategic allocation of financial
resources toward, post-approval commercialization.

We select disease targets and product candidates in which a small molecule would offer a significant benefit over existing products or would be the

first to market. We strive to advance our product candidate portfolio from discovery to commercial markets efficiently by utilizing a small group of talented
and highly-skilled employees working in conjunction with strategic outsource partners. We are unique in our approach to treat orphan diseases with orally-
administered, small molecules, identified by utilizing crystallography and structure-guided drug design. The principal elements of our strategy are:

● Focusing on High Value-Added Structure-Guided Drug Design Technologies. We utilize structure-guided drug design in order to most efficiently
develop new therapeutic candidates. Structure-guided drug design is a process by which we design a product candidate through detailed analysis
of the enzyme target, which the product candidate must inhibit in order to stop the progression of the disease or disorder. We believe that structure-
guided drug design is a powerful tool for the efficient development of small-molecule product candidates that have the potential to be safe and
effective. Our structure-guided drug design technologies typically allow us to design and synthesize multiple product candidates that inhibit the
same enzyme target, with the goal of establishing broad intellectual property protection and formulating compounds with competitive advantages.

● Selecting Inhibitors that are Promising Product Candidates. We start by selecting disease targets with well-understood biology and characteristics
that fit with our ability to utilize structure-guided drug design capabilities to build potent and specific enzyme inhibitors. Next, we narrow our
selection of these product candidates based on product characteristics, such as initial indications of safety and biologic activity on the target.

● Developing our Product Candidates Efficiently. An important element of our business strategy is to efficiently progress our product candidates

through the development process. In order to accomplish this, we typically strive for disease targets with a defined clinical and regulatory pathway
for approval or diseases where high unmet needs allow for frequent interactions with regulators. In addition, as we determine such relationships to
be appropriate or desirable, we control certain fixed costs and overhead by outsourcing with strategic partners and contractors or entering into
license agreements with third parties, including the U.S. Government. For example, our galidesivir research program is currently being developed
under U.S. Government contracts. By contracting with the U.S. Government and outsourcing certain aspects of our operations, we are able to
control overhead costs and focus financial resources directly where they provide the most benefit and reduce our business risk.

● Commercializing our Product Candidates Globally. A core part of our strategy is to commercialize our rare disease products globally. We have

established commercial teams in the United States and Europe for the commercialization of ORLADEYO, and we are continuing to build the
structure and expertise to commercialize our products in markets where we believe we can do this efficiently and effectively. We have also
established relationships with licensing and distribution partners in certain markets, including Japan, and will continue to seek such relationships
where we determine this to be an effective approach.

Products and Product Candidates

ORLADEYO (Berotralstat)

ORLADEYO is an oral, once-daily therapy discovered and developed by BioCryst for the prevention of hereditary angioedema (“HAE”) attacks.

HAE is a rare, severely debilitating and potentially fatal genetic condition with a prevalence of between 1 in 33,000 to 1 in 67,000 people. HAE symptoms
include recurrent episodes of edema in various locations, including the hands, feet, face, genitalia and airway. Airway swelling is particularly dangerous
and can lead to death by asphyxiation. In addition, patients often have bouts of severe abdominal pain, nausea and vomiting caused by swelling in the
intestinal wall. By inhibiting plasma kallikrein, ORLADEYO suppresses bradykinin production. Bradykinin is the mediator of acute swelling attacks in
HAE patients.

ORLADEYO was approved by the U.S. Food and Drug Administration (“FDA”) in December 2020 for prophylaxis to prevent attacks of HAE in
adults and pediatric patients 12 years and older. Our specialty pharmacy provider for ORLADEYO in the U.S. began shipping ORLADEYO to patients
with a prescription in the U.S. in December 2020. Through EMPOWER Patient Services, administered by our specialty pharmacy provider, we aim to
streamline access to therapy by providing each HAE patient and their healthcare provider with a single point of contact for access to ORLADEYO. A
dedicated care coordinator supports access for each patient with comprehensive financial support tools and reimbursement support.

ORLADEYO also received marketing and manufacturing approval from the Ministry of Health, Labor and Welfare (“MHLW”) in Japan in January

2021 for prophylactic treatment of HAE in adults and pediatric patients 12 years and older. ORLADEYO is the first and only prophylactic HAE medication
approved in Japan. On April 14, 2021, we announced that the Japanese National Health Insurance System (“NHI”) approved the addition of ORLADEYO
to the NHI drug price list on April 21, 2021. Torii, our collaborative partner commercializing ORLADEYO in Japan, launched ORLADEYO in Japan on
April 23, 2021. The NHI price listing triggered a $15 million milestone payment from Torii to us. In addition, under our agreement with Torii, we are
entitled to receive tiered royalty payments, ranging from 20% to 40% of net sales of ORLADEYO in Japan during each calendar year. See “Collaborations
and In-License Relationships” below for a description of our relationship with Torii. OrphanPacific, Inc., our representative partner in Japan, holds the
marketing authorization for ORLADEYO in Japan.

On April 30, 2021, we announced that the European Commission (“EC”) approved ORLADEYO for routine prevention of recurrent attacks of HAE
in adult and adolescent patients aged 12 years and older. The EC approval is applicable to all European Union (“EU”) member states plus Iceland, Norway,
and Liechtenstein. ORLADEYO is the first oral, once-daily prophylactic therapy for the prevention of HAE attacks approved in Europe. On June 3, 2021,
we announced the launch of ORLADEYO in Germany. Appropriate HAE patients aged 12 years and older in France currently have access to ORLADEYO
through an Autorisation Temporaire d’Utilisation de cohort, or Temporary Authorization for Use, granted by the French National Agency for Medicines
and Health Products Safety in March 2021.  In addition, we have also launched ORLADEYO in Norway and Sweden.

On May 12, 2021, we announced that the United Kingdom’s Medicines and Healthcare Regulatory Agency (“MHRA”) granted marketing
authorization for ORLADEYO for the routine prevention of recurrent HAE attacks in HAE patients 12 years and older. We announced on September 15,
2021 that the United Kingdom’s National Institute for Health and Care Excellence (“NICE”) recommended ORLADEYO for preventing recurrent attacks
of HAE in eligible patients 12 years and older if they have at least two attacks per month. With this recommendation, HAE patients in England, Wales, and
Northern Ireland will have access to the first oral, once-daily therapy for routine prevention of recurrent HAE attacks.

On June 16, 2021, we announced that the Israeli Ministry of Health has accepted the regulatory submission of ORLADEYO for the prevention of

recurrent attacks in patients with HAE 12 years and older and that the Israeli Ministry of Health has granted an accelerated review. In addition, we entered
into a distribution and supply agreement granting Neopharm Ltd., a corporation organized under the laws of the State of Israel, the exclusive rights to
commercialize ORLADEYO in Israel.

On August 25, 2021, we announced that the new drug submission for ORLADEYO was accepted for review by Health Canada for the prevention of

recurrent attacks in patients with HAE 12 years and older. We also announced that Swissmedic accepted the Company’s marketing authorization
application for ORLADEYO review.

On September 9, 2021, we announced that the Ministry of Health and Prevention (“MOHAP”) in the United Arab Emirates (“UAE”) granted

marketing authorization for ORLADEYO for the prevention of recurrent attacks in patients with HAE 12 years and older. To support commercialization
efforts in the UAE, we entered into a supply and distribution agreement with NewBridge Pharmaceuticals, which also covers the Gulf Cooperation Council
and Iraq.

On January 10, 2022, we announced that ORLADEYO is now covered by all major payors and national and regional pharmacy benefit managers in

the U.S.

On December 7, 2020, we entered into a Purchase and Sale Agreement (the “2020 RPI Royalty Purchase Agreement”) with RPI 2019 Intermediate

Finance Trust (“RPI”), pursuant to which we sold to RPI the right to receive certain royalty payments from the Company for a purchase price of $125
million in cash. On November 19, 2021, we entered into a second Purchase and Sale Agreement (the “2021 RPI Royalty Purchase Agreement” and
together with the 2020 RPI Royalty Purchase Agreement, (the “RPI Royalty Purchase Agreements”) with RPI, pursuant to which we sold to RPI the right
to receive certain royalty payments from the Company for a purchase price of $150 million in cash. On November 19, 2021, we also entered into a
Purchase and Sale Agreement (the “OMERS Royalty Purchase Agreement”) and collectively with the RPI Royalty Purchase Agreements, the “Royalty
Purchase Agreements”) with OCM IP Healthcare Holdings Limited, an affiliate of OMERS Capital Markets (“OMERS”), pursuant to which we sold to
OMERS the right to receive certain royalty payments from the Company for a purchase price of $150 million in cash. The transactions contemplated under
the Royalty Purchase Agreements are referred to herein as the “Royalty Sales.” Under the Royalty Purchase Agreements, RPI and OMERS are entitled to
receive tiered, sales-based royalties on net product sales of ORLADEYO in the U.S. and certain key European markets (collectively, the “Key Territories”),
and other markets where we sell ORLADEYO directly or through distributors (collectively, the “Direct Sales”). In addition, RPI and OMERS are entitled
to receive a tiered revenue share on amounts generally received by us on account of ORLADEYO sublicense revenue or net sales by licensees outside of
the Key Territories. See “Note 8(cid:0)Royalty Monetizations(cid:0)ORLADEYO and Factor D Inhibitors” in the Notes to Consolidated Financial Statements in Part
II, Item 8 of this report for additional information about our obligations under the Royalty Purchase Agreements.

We built out our U.S. commercial infrastructure in 2020 to support the launch of ORLADEYO in the U.S. in December 2020 and are continuing to
build our commercial infrastructure to support launches in Europe and elsewhere. Based on proprietary analyses of HAE prevalence and market research
studies with HAE patients, physicians, and payors in the U.S. and Europe, and our first full year of commercialization of  ORLADEYO in the U.S. in 2021,
we anticipate the commercial market for ORLADEYO has the potential to reach a global peak of more than $1 billion in annual sales. We expect at least 70
to 80 percent of our revenue at peak to come from the U.S. These expectations are subject to numerous risks and uncertainties that may cause our actual
results, performance, or achievements to be materially different. There can be no assurance that our commercialization methods and strategies will succeed,
or that the market for ORLADEYO will develop in line with our current expectations. See “Risk Factors(cid:0)Risks Relating to Our Business(cid:0)Risks Relating
to Drug Development and Commercialization(cid:0)There can be no assurance that our commercialization efforts, methods, and strategies for our products or
technologies will succeed, and our future revenue generation is uncertain” in Part I, Item 1A of this report for further discussion of these risks.

Complement-Mediated Diseases

The complement system is part of the body’s natural immune system and is responsible for helping the body eliminate microbes (including viral and

bacterial infections) and damaged cells. It is comprised of proteins that are primarily produced in the liver and circulate in the blood. Once activated, the
complement system stimulates inflammation, phagocytosis and cell lysis. Excessive or uncontrolled activation of the complement system can cause severe,
and potentially fatal, immune and inflammatory disorders. The complement system comprises biological cascades of amplifying enzyme cleavages
involving more than 30 proteins and protein fragments, and may be activated through three pathways: the classical pathway (initiated by antibody-antigen
complexes), the lectin pathway (initiated by lectin binding) and the alternative pathway (initiated by microbial surfaces). The alternative pathway also
provides a critical amplification loop for all three pathways, regardless of the initiating mechanism. Factor D is an essential enzyme in the alternative
pathway, thus making Factor D an attractive target to address complement-mediated diseases. Several rare diseases are known to be mediated by
dysregulation of the complement system.

BCX9930 is a novel, oral, potent, and selective small molecule inhibitor of Factor D, discovered by the Company and currently in clinical

development for the treatment of complement-mediated diseases. Based on the safety and proof-of-concept (“PoC”) data generated to date in patients with
paroxysmal nocturnal hemoglobinuria (“PNH”), the program has advanced to pivotal studies of oral BCX9930 (500 mg twice-daily) in PNH and to a
proof-of-concept trial of oral BCX9930 (500 mg twice-daily) in three renal complement-mediated diseases, C3 glomerulopathy (C3G), IgA nephropathy
(IgAN), and primary membranous nephropathy (PMN). We are working closely with regulators and key opinion leaders in hematology and nephrology to
map the advanced development strategy across a broad set of indications. Our goal is to develop oral BCX9930 as a monotherapy for complement-
mediated diseases.

We have completed a proof-of-concept trial in patients with PNH, including both treatment-naïve and those patients with an inadequate response to

C5 inhibitors.  Patients on BCX9930 have been allowed to roll over with continued follow-up into a long-term safety trial.  We continue to monitor the
patients who continue in the long-term safety trial.

On November 29, 2021, we announced the enrollment of the first patient in the REDEEM-2 pivotal trial with BCX9930 in patients with PNH.
REDEEM-2 is a randomized, placebo-controlled trial evaluating the efficacy and safety of BCX9930 (500 mg twice-daily) as monotherapy versus placebo
in PNH patients not currently receiving complement inhibitor therapy. In part 1 of this trial, patients will be randomized 2:1 to receive BCX9930 or placebo
under double-blind conditions for 12 weeks. All patients will receive BCX9930 in part 2 (weeks 13-52) to assess the long-term safety, tolerability, and
effectiveness of BCX9930, with patients randomized to placebo in part 1 switching to BCX9930 at the week 12 visit. The primary endpoint of REDEEM-2
is change from baseline in hemoglobin, as assessed at week 12.

On January 7, 2022, we announced the enrollment of the first patient in the REDEEM-1 pivotal trial with BCX9930 in patients with PNH.
REDEEM-1 is a randomized, open-label, active comparator-controlled comparison of the efficacy and safety of BCX9930 (500 mg twice-daily)
monotherapy in PNH patients with an inadequate response to a C5 inhibitor. In part 1 of this trial, patients who have not had an adequate response to a C5
inhibitor will be randomized 2:1 to discontinue their C5 inhibitor and receive BCX9930 as monotherapy or to continue receiving their C5 inhibitor for 24
weeks. All patients will receive BCX9930 in part 2 (weeks 25-52) to assess the long-term safety, tolerability, and effectiveness of BCX9930. Patients who
are randomized to C5 inhibitor therapy in part 1 will discontinue that therapy at the week 24 visit and start BCX9930 for part 2. The primary endpoint of
REDEEM-1 is change from baseline in hemoglobin, as assessed at weeks 12 to 24.

On February 22, 2022, we announced the enrollment of the first patient in the RENEW proof-of-concept basket study with BCX9930 in patients
with C3 glomerulopathy, IgA nephropathy, and primary membranous nephropathy.  RENEW is an open-label, multicenter, proof-of-concept study designed
to evaluate the safety, tolerability, and therapeutic potential of BCX9930 (twice-daily) administered for 24 weeks in patients with either C3G, IgAN, or
PMN.  All patients will be enrolled into one of three parallel study cohorts, based on confirmation of diagnosis and disease activity in a recent kidney
biopsy, and will receive BCX9930 for the 24-week treatment period.  The primary endpoint of RENEW is percent change from baseline in 24-hour urine
protein-to-creatinine ratio (uPCR), as assessed at week 24.

BCX9930 has received Orphan Drug and Fast Track designations from the FDA for the treatment of PNH. Orphan drug designation qualifies

BCX9930 for various development incentives, including tax credits for certain clinical costs, a waiver of the new drug application fee, and a designated
period of market exclusivity following approval. According to the FDA, the purpose of the Fast Track designation is to get important new drugs to patients
earlier by facilitating the development, and expediting the review, of drugs to treat serious conditions and meet an unmet medical need.

Under the RPI Royalty Purchase Agreements, RPI will be entitled to receive tiered, sales-based royalties on net product sales, if any, of BCX9930

and another earlier stage Factor D inhibitor, as well has tiered, profit share amounts of up to 3.0% from certain other permitted sales in certain markets. See
“Note 8(cid:0)Royalty Monetizations(cid:0)ORLADEYO and Factor D Inhibitors” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report
for additional information about our obligations under the RPI Royalty Purchase Agreements.

Fibrodysplasia Ossificans Progressiva (“FOP”)

FOP is an ultra-rare disease that affects approximately 1 in 2 million people worldwide. It is a severely disabling condition characterized by the

irregular formation of bone outside the normal skeleton, also known as heterotopic ossification (“HO”). HO can occur in muscles, tendons and soft tissue.
FOP patients progressively become bound by this irregular ossification, with restricted movement and fused joints, resulting in deformities and premature
mortality. In patients with FOP, minor trauma can result in rapid development of painful inflammatory masses. These progress over several weeks resulting
in the replacement of the affected soft tissue by permanent bone masses. There is no cure for this condition, and there are no approved treatments for FOP
in the U.S.

In 2018, we announced the advancement of a program exploring activin receptor-like kinase-2 (“ALK2”) inhibitors for treatment of FOP. ALK2

enzyme is a part of the normal signaling pathway for bone formation and responds to binding its specific ligands (bone morphogenic proteins, or BMPs),
by stimulating normal bone growth and renewal in healthy children and adults. Specific activating mutations of the ALK2 gene are seen in all cases of FOP.
An activating mutation in ALK2 is necessary for the disease to occur, making the ALK2 kinase an ideal drug target for treatment of FOP with an ALK2
kinase inhibitor.

The goal of our ALK2 inhibitor program is to discover and develop orally administered kinase inhibitor drug candidates that are able to slow or
prevent HO. In a phase 1 clinical trial in healthy volunteers, our lead compound, BCX9250, was safe and well tolerated at all doses studied, with linear and
dose-proportional exposure supporting once-daily dosing.

Peramivir Injection (RAPIVAB, RAPIACTA, PERAMIFLU)

RAPIVAB (peramivir injection) was developed under a $234.8 million contract from the Biomedical Advanced Research and Development
Authority within the U.S. Department of Health and Human Services (“BARDA/HHS”). In January 2010, our partner, Shionogi, received the first approval
for peramivir injection and launched it in Japan under the commercial name RAPIACTA. It is approved in Japan for the treatment of adults, children, and
infants with uncomplicated seasonal influenza and those patients at high-risk for complications associated with influenza. In August 2010, our partner,
Green Cross, received marketing and manufacturing approval from the Korean Food & Drug Administration under the commercial name PERAMIFLU to
treat patients with influenza A & B viruses, including pandemic H1N1 and avian influenza. See “Collaborations and In-License Relationships” below for a
discussion of these licensing arrangements.

Peramivir was also approved in the United States in 2014, Taiwan in 2016, Canada in 2017, and Australia in 2018. A Supplemental New Drug

Application (“sNDA”) was approved in the United States in February 2021, extending RAPIVAB’s availability for the treatment of acute uncomplicated
influenza to pediatric patients six months and older. Prior to this approval, peramivir had been indicated in the United States for pediatric patients two years
and older. In the United States, peramivir is indicated for the treatment of acute uncomplicated influenza in patients who have been symptomatic for no
more than two days.

In September 2018, the U.S. Department of Health and Human Services (“HHS”) awarded us a $34.7 million contract for the procurement of up to

50,000 doses of RAPIVAB over a five-year period to supply the Strategic National Stockpile for use in a public health emergency. We delivered 20,000
doses of RAPIVAB under this contract in 2019 for a total price of approximately $13.9 million. We delivered another 9,980 doses of RAPIVAB under this
contract in 2021 for a total price of approximately $6.9 million. On September 1, 2021, we announced that HHS exercised its option to purchase an
additional 10,000 doses of RAPIVAB under this contract for a total price of approximately $6.9 million. As a result, we expect to deliver at least one
shipment of 10,000 doses within the contract in 2022.

Galidesivir (BCX4430)

Galidesivir is a broad-spectrum antiviral (“BSAV”) that has been shown to be active against more than 20 RNA viruses in nine different families,

including filoviruses, togaviruses, bunyaviruses, arenaviruses, paramyxoviruses, coronaviruses and flaviviruses. In animal studies, galidesivir has
demonstrated survival benefits against a variety of serious pathogens, including Marburg, Yellow Fever, Ebola, and Zika viruses and from exposures to
aerosolized Marburg virus, an experimental condition designed to mimic an exposure scenario that could result during a bioterrorist attack.

The objective of our BSAV program is to develop galidesivir as a broad-spectrum therapeutic for viruses that pose a threat to national health and

security. The primary focus of the program is treatment of hemorrhagic fever viruses. Our galidesivir research program is currently being developed under
contracts with the National Institute of Allergy and Infectious Diseases within the HHS (“NIAID/HHS”) and BARDA/HHS.

NIAID/HHS funding has supported galidesivir’s development as a treatment for Marburg virus, Yellow Fever and Ebola virus. Since September

2013, NIAID/HHS has supported the development of galidesivir as a therapeutic for Ebola and Marburg viruses. As of the date hereof, all options under
our initial contract with NIAID/HHS have been awarded. The total amount under the initial contract, as amended, is $47.3 million, inclusive of the $1.4
million added to the contract in September 2021 to pay for certain additional costs, including additional manufacturing development costs and overhead.
This is the commencement of the closing out of the initial contract.

The contract we entered into with NIAID/HHS in August 2020 for the manufacture and evaluation of the safety, efficacy, and tolerability of

galidesivir, with potential aggregate funding of up to $43.9 million if all contract options are exercised, remains ongoing. NIAID/HHS made an initial
award of $6.3 million under this contract in 2020.

Since March 2015, BARDA/HHS has supported the development of galidesivir as a potential treatment for filoviruses. The total BARDA/HHS
contract value to advance the program through toxicology studies and manufacturing work to support a new drug application is $39.1 million if all contract
options are exercised. As of the date hereof, a total of $20.6 million has been awarded under exercised options within this contract.

Collaborations and In-License Relationships

Torii Pharmaceutical Co., Ltd. (“Torii”)

On November 5, 2019, we entered into a Commercialization and License Agreement with Torii (the “Torii Agreement”), granting Torii the exclusive

right to commercialize ORLADEYO for the prevention of HAE attacks in Japan. Under the Torii Agreement, we received an upfront, non-refundable
payment of $22.0 million. We received an additional milestone payment of $15.0 million in the second quarter of 2021 upon receipt from the NHI of a
reimbursement price approval for ORLADEYO.

Under the Torii Agreement, we are entitled to receive tiered royalty payments, ranging from 20% to 40% of annual net sales of ORLADEYO in

Japan during each calendar year. Torii’s royalty payment obligations are subject to customary reductions in certain circumstances, but may not be reduced
by more than 50% of the amount that otherwise would have been payable to us in the applicable calendar quarter. Torii’s royalty payment obligations
commenced upon the first commercial sale of ORLADEYO in Japan and expire upon the later of (i) the tenth anniversary of the date of first commercial
sale of ORLADEYO in Japan, (ii) the expiration of our patents covering ORLADEYO, and (iii) the expiration of regulatory exclusivity for ORLADEYO
in Japan. We are responsible for supplying Torii with its required amounts of ORLADEYO. The activities of the parties pursuant to the Torii Agreement are
overseen by a joint steering committee, composed of an equal number of representatives from each party to coordinate the development and
commercialization of ORLADEYO in Japan.

Under the Torii Agreement, we granted Torii a right of first negotiation (“ROFN”) to commercialize ORLADEYO in Japan for the acute treatment
of HAE attacks if we develop ORLADEYO for such indication and to commercialize any additional kallikrein inhibitor that we may develop in the future
for use in HAE in Japan. Under both ROFNs, if the parties do not agree to terms with respect to a definitive amendment to the Torii Agreement or new
agreement, as applicable, the terms of the amendment or agreement would be set by a third-party arbitrator.

Shionogi & Co., Ltd. (“Shionogi”)

In February 2007, we entered into a License, Development and Commercialization Agreement (as amended, supplemented or otherwise modified,
the “Shionogi Agreement”), an exclusive license agreement with Shionogi to develop and commercialize peramivir in Japan for the treatment of seasonal
and potentially life-threatening human influenza. In October 2008, we and Shionogi amended the Shionogi Agreement to expand the territory covered by
the agreement to include Taiwan. Under the terms of the Shionogi Agreement, Shionogi obtained rights to injectable formulations of peramivir in Japan in
exchange for a $14.0 million upfront payment. The license provided for development milestone payments (up to $21.0 million), which have all been paid,
and for commercial milestone payments (up to $95.0 million) in addition to double-digit (between 10% and 20%) royalty payments on product sales of
peramivir, in accordance with the terms of the Shionogi Agreement.

In December 2017, we, on behalf of JPR Royalty Sub LLC, a wholly-owned subsidiary of BioCryst (“Royalty Sub”), instituted arbitration

proceedings against Shionogi in order to resolve a dispute with Shionogi under the Shionogi Agreement regarding the achievement of sales milestones and
escalating royalties. The arbitration proceedings concluded with the decision that no sales milestones had been achieved and that royalties would remain the
same. The costs associated with the arbitration proceedings are recoverable from the assets of Royalty Sub in accordance with the terms of the Indenture
and servicing agreement relating to the PhaRMA Notes (each as defined below under “Shionogi Royalty Monetization and Non-Recourse Notes Payable”).

Generally, all payments under the Shionogi Agreement are non-refundable and non-creditable, but they are subject to audit. Shionogi is responsible
for all development, regulatory, and marketing costs in Japan. The term of the Shionogi Agreement is from February 28, 2007 until terminated. Either party
may terminate the Shionogi Agreement in the event of an uncured breach. Shionogi has the right of termination without cause. In the event of termination,
all license and rights granted to Shionogi shall terminate and shall revert back to us. We developed peramivir under a license from the University of
Alabama Birmingham (“UAB”) and have paid sublicense payments to UAB on the upfront payments and will owe sublicense payments on any future
event payments and/or royalties received by us from Shionogi.

Shionogi Royalty Monetization and Non-Recourse Notes Payable.

On March 9, 2011, we completed a $30.0 million financing transaction to monetize certain future royalty and milestone payments under the
Shionogi Agreement. Pursuant to the transaction, Royalty Sub issued $30.0 million in aggregate principal amount of its PhaRMA Senior Secured 14.0%
Notes due 2020 (the “PhaRMA Notes”) in a private placement to institutional investors. The PhaRMA Notes were issued under an indenture, dated as of
March 9, 2011 (the “Indenture”), by and between Royalty Sub and U.S. Bank National Association, as Trustee. We received net proceeds of $22.7 million
from this transaction.

As part of the transaction, we entered into a purchase and sale agreement, dated as of March 9, 2011, with Royalty Sub, whereby we transferred to
Royalty Sub, among other things, (i) our rights to receive commercial royalty and milestone payments from Shionogi under the Shionogi Agreement and
(ii) the right to receive payments under a Japanese yen/US dollar foreign currency hedge arrangement, which was put into place by us in connection with
the transaction and expired in November 2020. Royalty payments are paid by Shionogi in Japanese yen, and milestone payments are paid in U.S. dollars.
Our collaboration with Shionogi was not impacted by this transaction.

Principal and interest on the PhaRMA Notes are payable from, and are secured by the rights to royalty and milestone payments under the Shionogi

Agreement, which were transferred by us to Royalty Sub. The PhaRMA Notes bear interest at 14.0% per annum, payable annually in arrears on September
1st of each year (the “Payment Date”). We remain entitled to receive any royalties and milestone payments related to sales of peramivir by Shionogi
following repayment by Royalty Sub of the PhaRMA Notes.

Royalty Sub’s obligations to pay principal and interest on the PhaRMA Notes are obligations solely of Royalty Sub and are without recourse to any
other person, including the Company, except to the extent of our pledge of our equity interests in Royalty Sub in support of the PhaRMA Notes. We may,
but are not obligated to, make capital contributions to a capital account that may be used to redeem, or on up to one occasion pay any interest shortfall on,
the PhaRMA Notes.

In September 2014, Royalty Sub was unable to pay the full amount of interest payable in September 2013 by the next succeeding payment date for

the PhaRMA Notes, which was September 1, 2014. This inability constituted an event of default under the terms of the Indenture. Accordingly, we
classified the PhaRMA Notes and related accrued interest as current liabilities on our balance sheet since that time. The PhaRMA Notes matured on
December 1, 2020, at which time the outstanding principal amount of the PhaRMA Notes of $30.0 million, together with all accrued and unpaid interest of
$20.6 million, was due in full. The failure by Royalty Sub to repay in full the outstanding principal amount of the PhaRMA Notes, together with any
accrued and unpaid interest, at the December 1, 2020 final maturity date, constituted an additional event of default under the PhaRMA Notes. As a result of
the continuing events of default under the PhaRMA Notes, the holders of the PhaRMA Notes may foreclose on the collateral securing the PhaRMA Notes
and our equity interests in Royalty Sub, and they may exercise other remedies available to them under the Indenture in respect of the PhaRMA Notes. In
such event, we may not realize the benefit of future royalty payments, if any, that might otherwise accrue to us following repayment of the PhaRMA Notes
and we might otherwise be adversely affected. Due to the non-recourse nature of the PhaRMA Notes, in the event of any potential foreclosure, we believe
the primary impact to us would be the loss of future royalty payments, if any, from Shionogi and the legal costs associated with retiring the PhaRMA
Notes. As a result, we do not currently expect the continuing events of default on the PhaRMA Notes to have a significant impact on our future results of
operations or cash flows. However, there can be no assurance that this will be the case or that we will not otherwise be adversely affected as a result of the
continuing events of default under the PhaRMA Notes.

As of December 31, 2021, the PhaRMA Notes remained in default. We wrote off the balance due under the PhaRMA Notes to other income as a

debt extinguishment as of December 31, 2021. See “Note 8−Royalty Monetizations−RAPIACTA−Non-Recourse Notes Payable−Debt Extinguishment” in
the Notes to Consolidated Financial Statements in Part II, Item 8 of this report for additional information about the write-off.

The Indenture does not contain any financial covenants. The Indenture includes customary representations and warranties of Royalty Sub,

affirmative and negative covenants of Royalty Sub, events of default and related remedies, and provisions regarding the duties of the Trustee,
indemnification of the Trustee, and other matters typical for indentures used in structured financings of this type.

Green Cross Corporation (“Green Cross”)

In June 2006, we entered into an agreement with Green Cross to develop and commercialize peramivir in Korea. Under the terms of the agreement,
Green Cross is responsible for all development, regulatory, and commercialization costs in Korea and we are entitled to share in profits resulting from the
sale of peramivir in Korea, including the sale of peramivir to the Korean government for stockpiling purposes. Furthermore, Green Cross will pay us a
premium over its cost to supply peramivir for development and any future marketing of peramivir products in Korea. Both parties have the right to
terminate the agreement in the event of an uncured material breach. In the event of termination, all rights, data, materials, products, and other information
would be transferred to us.

Albert Einstein College of Medicine of Yeshiva University and Industrial Research, Ltd. (“AECOM” and “IRL,” respectively)

In June 2000, we licensed a series of potent inhibitors of Purine Nucleoside Phosphorylase (“PNP”) from AECOM and IRL (together, the
“Licensors”). The lead product candidate from this collaboration is forodesine. We have obtained worldwide exclusive rights to develop and ultimately
distribute it, or any other, product candidates that might arise from research on these inhibitors. We have the option to expand our license agreement with
the Licensors to include other inventions in the field made by the investigators or employees of the Licensors. Under this agreement, as amended and
restated, we have agreed to use commercially reasonable efforts to develop these drugs and to pay certain milestone payments for each licensed product
(which range in the aggregate from $1.4 million to almost $4.0 million per indication) for future development, single digit royalties on net sales of any
resulting product made by us, and to share a portion of future payments received from other third-party partners, if any. In addition, we have agreed to pay
annual license fees, which can range from $150,000 to $500,000, that are creditable against actual royalties and other payments due to the Licensors. The
Licensors have also granted us an exclusive worldwide license of galidesivir for any antiviral use.

The University of Alabama at Birmingham (“UAB”)

We currently have agreements with UAB for influenza neuraminidase and complement inhibitors. Under the terms of these agreements, UAB

performed specific research for us in return for research payments and license fees. UAB has granted us certain rights to any discoveries in these areas
resulting from research developed by UAB or jointly developed with us. We have agreed to pay single digit royalties on sales of any resulting product and
to share in future payments received from other third-party partners. We have completed the research under the UAB agreements. These two agreements
have initial 25-year terms, are automatically renewable for five-year terms throughout the life of the last patent and are terminable by us upon three
months’ notice and by UAB under certain circumstances. Upon termination, both parties shall cease using the other parties’ proprietary and confidential
information and materials, the parties shall jointly own joint inventions, and UAB shall resume full ownership of all UAB licensed products. There is
currently no activity between us and UAB on these agreements, but when we license this technology, such as in the case of the Shionogi and Green Cross
agreements, or commercialize products related to these programs, we will owe sublicense fees or royalties on amounts received.

Government Contracts

RAPIVAB (Peramivir Injection)

In September 2018, HHS awarded us a $34.7 million contract for the procurement of up to 50,000 doses of RAPIVAB over a five-year period,

including an initial base order of 10,000 doses. In each of September 2019, 2020, and 2021, HHS exercised its options to purchase an additional 10,000
doses of RAPIVAB. We delivered a total of 20,000 doses of RAPIVAB and recorded approximately $13.9 million of product sales in 2019. In 2021, we
delivered another shipment of 9,980 doses within the contract, totaling approximately $6.9 million in product sales. We expect to deliver at least one
shipment of 10,000 doses within the contract in 2022, totaling approximately $6.9 million in product sales. The RAPIVAB purchases by HHS will supply
the Strategic National Stockpile, the nation’s largest supply of life-saving pharmaceuticals and medical supplies for use in a public health emergency.

Galidesivir

In March 2015, BARDA/HHS awarded us a contract for the continued development of galidesivir as a potential treatment for diseases caused by
RNA pathogens, including filoviruses. This BARDA/HHS contract has a potential value of $39.1 million if all contract options are exercised. As of the
date of this report, a total of $20.6 million has been awarded under exercised options within this contract.

In September 2013, NIAID/HHS contracted with us for the development of galidesivir as a treatment for Marburg, and subsequently, Yellow Fever
and Ebola virus disease. All options under this contract have been awarded, and the total value of the contract, as amended, is $47.3 million, inclusive of
the $1.4 million added to the contract in September 2021 to pay for certain additional costs, including additional manufacturing development costs and
overhead. This contract is in the process of being closed out.

In August 2020, NIAID/HHS awarded us a new $43.9 million contract for the manufacture and evaluation of the safety, efficacy, and tolerability of

galidesivir. NIAID/HHS made an initial award of $6.3 million under this new contract.

The contracts with BARDA/HHS and NIAID/HHS are cost-plus-fixed-fee contracts. That is, we are entitled to receive reimbursement for all costs

incurred in accordance with the contracts provisions that are related to the development of peramivir and galidesivir plus a fixed fee, or profit.
BARDA/HHS and NIAID/HHS will make periodic assessments of progress and the continuation of the contract is based on our performance, the
timeliness and quality of deliverables, and other factors. The government has rights under certain contract clauses to terminate these contracts. These
contracts are also terminable by the government at any time for breach or without cause.

Patents and Proprietary Information

Our success will depend in part on our ability to obtain and enforce patent protection for our products, methods, processes, and other proprietary
technologies, preserve our trade secrets, and operate without infringing on the proprietary rights of other parties, both in the United States and in other
countries. We own or have rights to certain proprietary information, proprietary technology, issued and allowed patents and patent applications which relate
to compounds we are developing. We actively seek, when appropriate, protection for our products, proprietary technology, and proprietary information by
means of U.S. and foreign patents, trademarks, and contractual arrangements. In addition, we rely upon trade secrets and contractual arrangements to
protect certain of our proprietary information, proprietary technology, and products and product candidates.

The patent positions of companies like ours are generally uncertain and involve complex legal and factual questions. Our ability to maintain and

solidify our proprietary position for our technology will depend on our success in obtaining effective patent claims and enforcing those claims once
granted. We do not know whether any of our patent applications or those patent applications that we license will result in the issuance of any patents. Our
issued patents and those that may issue in the future, or those licensed to us, may be challenged, invalidated, rendered unenforceable or circumvented,
which could limit our ability to stop competitors from marketing related products or the length of term of patent protection that we may have for our
products. In addition, the rights granted under any issued patents may not provide us with competitive advantages against competitors with similar
compounds or technology. Furthermore, our competitors may independently develop similar technologies or duplicate any technology developed by us in a
manner that does not infringe our patents or other intellectual property. Because of the extensive time required for development, testing and regulatory
review of a potential product, it is possible that, before any of our product candidates or those developed by our partners can be commercialized, any
related patent may expire or remain in force for only a short period following commercialization, thereby reducing any advantage of the patent.

As of December 31, 2021, we have been issued approximately 28 U.S. patents that expire between 2023 and 2039 and that relate to our kallikrein

inhibitor compounds, neuraminidase inhibitor compounds, BSAV compounds, PNP inhibitor compounds, and complement-mediated disease program
compounds. We have licensed a number of compounds protected by certain composition of matter patents from AECOM and IRL, totaling three additional
U.S. patents that expire between 2023 and 2029. Additionally, we have approximately 25 Patent Cooperation Treaty or U.S. patent applications pending
related to kallikrein inhibitor compounds, neuraminidase inhibitor compounds, BSAV compounds, PNP inhibitor compounds, FOP program compounds,
and complement-mediated disease program compounds. Our pending applications may not result in issued patents, our patents may not cover the products
of interest or may not be enforceable in all, or any jurisdictions and our patents may not provide us with sufficient protection against competitive products
or otherwise be commercially viable. After expiration of composition of matter patents for our products and product candidates, we may rely on data
exclusivity, or in some cases, method of use patents. The enforceability of these patents varies from jurisdiction to jurisdiction and may not be allowed or
enforceable in some territories where we may seek approval. We may not have the funds to continue patent prosecution or to defend all of our existing
patents in our current patent estate and may selectively abandon patents or patent families worldwide or in certain territories.

Our success is also dependent upon the skills, knowledge and experience of our scientific and technical personnel, none of which is patentable. To
help protect our rights, we require all employees, consultants, advisors and partners to enter into confidentiality agreements, which prohibit the disclosure
of confidential information to anyone outside of BioCryst and, where possible, require disclosure and assignment to us of their ideas, developments,
discoveries, and inventions. These agreements may not provide adequate protection for our trade secrets, know-how, or other proprietary information in the
event of any unauthorized use or disclosure or the lawful development by others of such information.

Competition

The pharmaceutical and biotechnology industries are intensely competitive. Many companies, including biotechnology, chemical and pharmaceutical

companies, are actively engaged in activities similar to ours, including research, development, and commercialization of drugs for the treatment of rare
medical conditions. Many of these companies have substantially greater financial and other resources, larger research and development staffs, and more
extensive commercial and manufacturing organizations than we do. In addition, many have considerable experience in preclinical testing, clinical trials,
and other regulatory approval procedures. In addition, there are also academic institutions, governmental agencies and other research organizations who
conduct research in areas in which we are working. We expect to encounter significant competition for any of the pharmaceutical products we plan to
develop. Companies that successfully complete clinical trials, obtain required regulatory approvals, and commence commercial marketing and sales of their
products may achieve a significant competitive advantage.

In order to compete successfully, we must develop proprietary positions in patented drugs for therapeutic markets that have not been satisfactorily

addressed by conventional research strategies and, in the process, expand our expertise in structure-based drug design. Our product candidates, even if
successfully tested and developed, may not be adopted by physicians over other products and may not offer economically feasible alternatives to other
therapies.

HAE

HAE is an autosomal dominant disease characterized by painful, unpredictable, recurrent attacks of inflammation affecting the hands, feet, face,
abdomen, urogenital tract, and the larynx. The inflammation can be disfiguring, debilitating, or in the case of laryngeal attacks, life-threatening. Prevalence
for HAE is uncertain but is estimated to be approximately 1 case per 33,000 to 67,000 persons without known differences among ethnic groups and is
caused by deficient (Type I) or dysfunctional (Type II) levels of C1-Inhibitor (“C1-INH”), a naturally occurring molecule that is known to inhibit kallikrein,
bradykinin, and other serine proteases in the blood. If left untreated, HAE can result in a mortality rate as high as 40% primarily due to upper airway
obstruction. There are several licensed therapies for HAE, including the following:

12

 
 
 
 
 
 
 
 
 
 
● C1-INH replacement therapy is available as an acute therapy (Berinert®) and as a prophylactic therapy (Haegarda® and Cinryze®). These

therapies are dosed subcutaneously and intravenously. Recombinant C1-INH (Ruconest®) is also available as an acute therapy.

● Kallikrein Inhibitors (cid:0) Kalbitor® (ecallantide) is a specific recombinant plasma kallikrein inhibitor that is dosed subcutaneously by healthcare

providers to treat acute HAE attacks. Takhzyro® (lanadelumab-flyo) is a monoclonal antibody approved for prophylaxis of HAE attacks and
can be self-administered as a subcutaneous injection.

● Bradykinin receptor antagonist (cid:0) Firazyr® (icatibant) and generic icatibant are indicated for the treatment of acute attacks and is administered

by subcutaneous administration.

● Other medications (cid:0) Prophylactic administration of synthetic attenuated androgens (generically available as danazol or stanozolol) has been

utilized to reduce the frequency or severity of attacks. However, long-term use of danazol or stanozolol may result in liver damage,
virilization and arterial hypertension. Six-month liver function tests, annual lipid profiles, and biennial hepatic ultrasound are recommended
for patients on chronic androgen therapy.

Several rare diseases are known to be mediated by defects of the complement system, including PNH, atypical hemolytic uremic syndrome
(“aHUS”), complement 3 glomerulopathy (“C3G”), and myasthenia gravis. Alexion, AstraZeneca Rare Disease’s Soliris® (eculizumab) is a C5 inhibitor
approved for PNH, aHUS, myasthenia gravis, and neuromyelitis optica spectrum disorder. Soliris had global sales of over $1.9 billion in 2021. Alexion
also received FDA approval for Ultomiris® (ravulizumab), a longer-acting C5 inhibitor, as a treatment for PNH in late 2018 and aHUS in late 2019. Global
sales for Ultomiris were $688 million in 2021. Apellis Pharmaceuticals, Inc.’s Empaveli® is a C3 inhibitor approved for PNH in the U.S. and Europe in
2021.

FOP is a rare, severely disabling condition characterized by HO. HO can occur in muscles, tendons, and soft tissue. FOP patients progressively

become bound by this irregular ossification, with restricted movement and fused joints, resulting in deformities and premature mortality. There are
currently no approved treatments for FOP in the U.S.

Antivirals

The pharmaceutical market for products that prevent or treat influenza is very competitive. Key competitive factors for RAPIVAB (peramivir
injection) include, among others, efficacy, ease of use, safety, price and cost-effectiveness, storage and handling requirements, and reimbursement. A
number of products are currently available in the U.S. and/or other counties, including Japan, for the prevention or treatment of influenza, including
seasonal flu vaccines, F. Hoffmann-La Roche Ltd.’s (“Roche”) TAMIFLU® (oseltamivir), generic oseltamivir, GlaxoSmithKline plc’s (“GSK”)
RELENZA®, Genentech and Shiongi’s XOFLUZA® and Daiichi Sankyo Co., Ltd.’s INAVIR®. In addition, FUJIFILM Corporation’s favipiravir, a
polymerase inhibitor, is approved in Japan.

Various government entities throughout the world are offering incentives, grants, and contracts to encourage additional investment into preventative

and therapeutic agents against influenza, which may have the effect of further increasing the number of our competitors and/or providing advantages to
certain competitors.

Galidesivir is a product candidate in our BSAV research program and is currently being developed under contracts with NIAID/HHS and

BARDA/HHS. The objective of our BSAV program is to develop galidesivir as a broad-spectrum therapeutic for viruses that pose a threat to national health
and security. The U.S. Government is investing in a number of programs intended to address gaps in its medical countermeasure plan.

Research and Development

We initiated our research and development activities in 1986. We have assembled a scientific research staff with expertise in a broad base of
advanced research technologies, including protein biochemistry, X-ray crystallography, chemistry, and pharmacology. Our research facilities, located in
Birmingham, Alabama, include protein biochemistry and organic synthesis laboratories, testing facilities, X-ray crystallography, computer and graphics
equipment and facilities to make product candidates on a small scale for early-stage clinical trials.

Compliance

We conduct our business in an ethical, fair, honest, and lawful manner. We act responsibly, respectfully, and with integrity in our relationships with

patients, health care professionals, collaborators, governments, regulatory entities, stockholders, suppliers, and vendors.

In order to ensure compliance with applicable laws and regulations, our Chief Financial Officer, Chief Legal Officer, and Chief People Officer

oversee compliance training, education, auditing, and monitoring; enforce disciplinary guidelines for any infractions of our corporate polices; implement
new policies and procedures; respond to any detected issues; and undertake corrective action procedures. Our controls address compliance with laws and
regulations that govern public pharmaceutical companies, including, but not limited to, the following: federal and state law, such as the Sarbanes-Oxley Act
of 2002 and the U.S. Foreign Corrupt Practices Act of 1977; Nasdaq listing requirements; the regulations of the Financial Industry Regulatory Authority,
the SEC, the FDA, and HHS; and applicable laws and regulations administered by foreign regulatory authorities, including those of the EU, the U.K., and
Japan. Our standard operating procedures are designed to provide a framework for corporate governance in accordance with ethical standards and best legal
practices.

Government Regulation

The FDA regulates the pharmaceutical and biotechnology industries in the U.S., and our product candidates are subject to extensive and rigorous

domestic government regulations prior to commercialization. The FDA regulates, among other things, the development, testing, manufacture, safety,
efficacy, record-keeping, labeling, storage, approval, advertising, promotion, sale and distribution of pharmaceutical products. In foreign countries, our
products are also subject to extensive regulation by foreign governments. These government regulations are a significant factor in the production and
marketing of any pharmaceutical products that we develop. Failure to comply with applicable FDA and other regulatory requirements at any stage during
the regulatory process may subject us to sanctions, including:

● delays;
● warning letters;
● fines;
● product recalls or seizures;
● injunctions;
● penalties;
● refusal of the FDA to review pending market approval applications or supplements to approval applications;
● total or partial suspension of production;
● civil penalties;
● withdrawals of previously approved marketing applications; and
● criminal prosecutions.

The regulatory review and approval process is lengthy, expensive, and uncertain. Before obtaining regulatory approvals for the commercial sale of
any products, we or our partners must demonstrate that our product candidates are safe and effective for use in humans. The approval process takes many
years, substantial expenses may be incurred, and significant time may be devoted to clinical development.

The policies of the FDA and foreign regulatory authorities may change, and additional government regulations may be enacted which could prevent
or delay regulatory approval of our product candidates or approval of new indications for our existing products. We cannot predict the likelihood, nature, or
extent of adverse governmental regulation that might arise from future legislative or administrative action, either in the United States or abroad.

FDA Regulation

Before testing potential product candidates in humans, we carry out laboratory and animal studies to determine safety and biological activity. After

completing preclinical trials, we must file an investigation new drug application (“IND”), including a proposal to begin clinical trials, with the FDA. Thirty
days after filing an IND, a phase 1 human clinical trial can start, unless the FDA places a hold on the trial.

Clinical trials to support a new drug application (“NDA”) are typically conducted in three sequential phases, but the phases may overlap.

Phase 1 — During phase 1, which involves the initial introduction of the drug into healthy volunteers, the drug is tested to assess metabolism,

pharmacokinetic, and pharmacological actions and safety, including side effects associated with increasing doses.

Phase 2 — Phase 2 usually involves trials in a limited patient population to: (1) assess the efficacy of the drug in specific, targeted indications; (2)

assess dosage tolerance and optimal dosage; and (3) identify possible adverse effects and safety risks.

Phase 3 (pivotal) — If a compound is found to be potentially effective and to have an acceptable safety profile in phase 2 evaluations, phase 3
clinical trials, also called pivotal studies, major studies, or advanced clinical trials, are undertaken to further demonstrate clinical efficacy and to further test
for safety within an expanded patient population at geographically dispersed clinical trial sites. In general, the FDA requires that at least two adequate and
well-controlled phase 3 clinical trials be conducted.

Initiation and completion of the clinical trial phases are dependent on several factors, including things that are beyond our control. For example, the
clinical trials cannot begin at a particular site until that site receives approval from its Institutional Review Board (“IRB”), which reviews the protocol and
related documents. This process can take several weeks to several months. In addition, clinical trials are dependent on patient enrollment, but the rate at
which patients enroll in the study depends on:

● willingness of investigators to participate in a study;
● ability of clinical sites to obtain approval from their IRB;
● the availability of the required number of eligible subjects to be enrolled in a given trial;
● the availability of existing or other experimental drugs for the disease we intend to treat;
● the willingness of patients to participate; and
● the patients meeting the eligibility criteria.

Delays in planned patient enrollment may result in increased expense and longer development timelines.

After successful completion of the required clinical testing, generally an NDA is submitted. Upon receipt of the NDA, the FDA will review the
application for completeness. Within 60 days, the FDA will determine if the application is sufficiently complete to warrant full review and will consider the
application “filed” at that time. Also upon receipt of the application, the FDA will assign a review priority to the application. Priority review applications
are usually reviewed within 6 months; standard review applications are usually reviewed within 10 months. The FDA may refer NDAs for new molecular
entities to an appropriate advisory committee for review and evaluation in regard to providing a recommendation as to whether the application should be
approved. The FDA is not bound to follow the recommendation of an advisory committee.

Following the review of the application, which may include requests for additional information from the sponsor and results from inspections of

manufacturing and clinical sites, the FDA will issue an “action letter” on the application. The action letter will either be an “approval letter,” in which case
the product may be lawfully marketed in the United States, or a “complete response letter.” A complete response letter will state that the FDA cannot
approve the NDA in its present form and, usually, will describe all of the specific deficiencies that the FDA has identified in the application. The complete
response letter, when possible, will include the FDA’s recommended actions to place the application in a condition for approval. Deficiencies can be minor
(e.g., labeling changes) or major (e.g., requiring additional clinical trials). A complete response letter may also be issued before the FDA conducts the
required facility inspection and/or reviews labeling, leaving the possibility that additional deficiencies in the original NDA could be subsequently cited. An
applicant receiving a complete response letter is permitted to resubmit the NDA addressing the identified deficiencies (in which case a new two- or six-
month review cycle will begin), or withdraw the NDA. The FDA may consider a failure to take action within one year of a complete response letter to be a
request to withdraw, unless the applicant has requested an extension of time in which to resubmit the NDA. If the FDA approves an NDA, the marketing of
the product will be limited to the particular disease states and conditions of use that are described in the product label. The FDA strictly regulates
marketing, labeling, advertising, and promotion of products that are placed on the market. The FDA and other agencies actively enforce the laws and
regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to
significant liability, including investigation by federal and state authorities.

Approved drugs that are manufactured or distributed in the U.S. pursuant to FDA approvals are subject to pervasive and continuing regulation by the

FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and
promotion, and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding new indications or
other labeling claims and some manufacturing and supplier changes, are subject to prior FDA review and approval. The FDA may impose a number of
post-approval requirements as a condition of approval of an NDA. For example, the FDA may require post-marketing testing, including phase 4 clinical
trials, and surveillance programs to further assess and monitor the product's safety and effectiveness after commercialization.

We and all of our contract manufacturers are also required to comply with the applicable FDA current Good Manufacturing Practice, or cGMP,

regulations during clinical development and to ensure that the product can be consistently manufactured to meet the specifications submitted in an NDA.
The cGMP regulations include requirements relating to product quality, as well as the corresponding maintenance of records and documentation.
Manufacturing facilities must be approved by the FDA before they can be used to manufacture our products. Based on an inspection, the FDA determines
whether manufacturing facilities are in compliance with applicable regulations. Manufacturing facilities in non-United States countries that are utilized to
manufacture drugs for distribution into the United States are also subject to inspection by the FDA. Additionally, failure to comply with local regulatory
requirements could affect production and availability of product in relevant markets.

Orphan Drugs

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

disease or condition that affects fewer than 200,000 individuals in the U.S. Orphan drug designation, if sought, must be requested before submitting an
NDA. After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA.
Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. The first NDA applicant
with FDA orphan drug designation for a particular active ingredient to receive FDA approval of the designated drug for the disease indication for which it
has such designation, is entitled to a seven-year exclusive marketing period (“Orphan drug exclusivity”) in the U.S. for that product, for that indication.
During the seven-year period, the FDA may not finally approve any other applications to market the same drug for the same disease, except in limited
circumstances, such as a showing of clinical superiority to the product with Orphan drug exclusivity or if the license holder cannot supply sufficient
quantities of the product. Orphan drug exclusivity does not prevent the FDA from approving a different drug for the same disease or condition, or the same
drug for a different disease or condition, provided that the sponsor has conducted appropriate clinical trials required for approval. Among the other benefits
of orphan drug designation are tax credits for certain research and a waiver of the NDA application user fee for the orphan indication.

Fast Track Designation

Under the Fast Track program, the sponsor of an IND may request the FDA to designate the drug candidate as a Fast Track drug if it is intended to
treat a serious condition and fulfill an unmet medical need. The FDA must determine if the drug candidate qualifies for Fast Track designation within 60
days of receipt of the sponsor's request. Once the FDA designates a drug as a Fast Track candidate, it is required to facilitate the development and expedite
the review of that drug by providing more frequent communication with, and guidance to, the sponsor.

In addition to other benefits, such as greater interactions with the FDA, the FDA may initiate review of sections of a Fast Track drug's NDA before

the application is complete. This rolling review is available if the applicant provides, and the FDA approves, a schedule for the submission of the remaining
information and the applicant pays applicable user fees. However, the FDA's review period as specified under PDUFA V for filing and reviewing an
application does not begin until the last section of the NDA has been submitted. Additionally, the Fast Track designation may be withdrawn by the FDA if
the FDA believes that the designation is no longer supported by data emerging in the clinical trial process.

16

 
 
 
 
 
 
 
 
 
 
Foreign Regulation

In addition to regulations in the United States, we are subject to a variety of foreign regulatory requirements governing human clinical trials and
marketing approval, commercial sales, and distribution of drugs. The foreign regulatory approval process includes all of the risks associated with FDA
approval set forth above, as well as additional country-specific regulations. Whether or not we obtain FDA approval for a product, we must obtain approval
of a product by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those
countries. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval. The
requirements governing the conduct of clinical trials, product licensing, pricing, and reimbursement vary greatly from country to country.

The various phases of pre-clinical and clinical research in the European Union (the “EU”) are subject to significant regulatory controls. Pursuant to

the Clinical Trials Directive 2001/20/EC, as amended (the “Clinical Trials Directive”), a system for the approval of clinical trials in the EU has been
implemented through national legislation of the member states. Under this system, approval must be obtained from the national competent authority of each
EU member state in which a clinical trial is planned to be conducted. A clinical trial application (“CTA”) is submitted, which must be supported by an
investigational medicinal product dossier and further supporting information prescribed by the Clinical Trials Directive and other applicable guidance
documents, including but not limited to the clinical trial protocol. Further, a clinical trial may only be started after an independent ethics committee has
issued a favorable opinion on the CTA in that country.

In April 2014, the EU adopted a new Clinical Trials Regulation (EU) No 536/2014 (the “Regulation”), which is set to replace the current Clinical

Trials Directive. The Regulation came into effect in January 2022 with a three-year transition period in which clinical trial sponsors will be able to choose
among different submission pathways. The Regulation, which is directly applicable in all EU member states, aims to simplify and streamline the approval
of clinical trials in the EU. For instance, the Regulation provides for a streamlined application procedure via a single entry point and strictly defined
deadlines for the assessment of clinical trial applications.

Manufacturing and import into the EU of investigational medicinal products for use in clinical trials is subject to the holding of appropriate

authorizations and must be carried out in accordance with cGMP.

Under EU regulatory systems, we may submit marketing authorizations either under a centralized or decentralized procedure. The centralized
procedure provides for the grant of a single marketing authorization that is valid for all EU member states. Under the centralized procedure, a single
marketing authorization application is submitted to the Committee for Medicinal Products for Human Use of the European Medicines Agency (“EMA”),
which then makes a recommendation to the European Commission (“EC”). The EC makes the final determination on whether to approve the application. 
The decentralized procedure provides for mutual recognition of national approval decisions, and the holder of a national marketing authorization may
submit an application to the remaining member states.

The United Kingdom’s (“U.K.”) exit from the EU, or Brexit, has caused political and economic uncertainty, including in the regulatory framework

applicable to our operations and product candidates, and this uncertainty may persist for years.  From January 1, 2021, the Medicines and Healthcare
products Regulatory Agency (“MHRA”) is the U.K.’s standalone medicines and medical devices regulator. As a result of the Northern Ireland protocol,
different rules apply in Northern Ireland than in England, Wales and Scotland (together, Great Britain or “GB”). Northern Ireland continues to follow the
EU regulatory regime, but its national competent authority remains the MHRA. The MHRA has published a draft guidance on how various aspects of the
U.K. regulatory regime for medicines will operate in GB and in Northern Ireland following the expiry of the Brexit transition period on December 31,
2020. The guidance includes clinical trials, marketing authorizations, importing, exporting and pharmacovigilance and is relevant to any business involved
in the research, development or commercialization of medicines in the U.K. The U.K. regulatory regime largely mirrors that of the EU.

Under the Japanese regulatory system administered by the Japanese Pharmaceuticals and Medical Devices Agency (“PMDA”), pre-marketing
approval and clinical studies are required for all pharmaceutical products. To obtain manufacturing/marketing approval, we must submit an application for
approval to the Ministry of Health, Labor and Welfare (“MHLW”) with results of nonclinical and clinical studies to show the quality, efficacy, and safety of
a new drug. A data compliance review, good Clinical Practices, or GCP, on-site inspection, cGMP audit, and detailed data review are undertaken by the
PMDA. The application is then discussed by the committees of the Pharmaceutical Affairs and Food Sanitation Council (“PAFSC”). Based on the results of
these reviews, the final decision on approval is made by the MHLW. In Japan, the National Health Insurance system maintains a Drug Price List specifying
which pharmaceutical products are eligible for reimbursement, and the MHLW sets the prices of the products on this list. The price will be determined
within 60 to 90 days following approval unless the applicant disagrees, which may result in extended pricing negotiations. The government generally
introduces price cut rounds every other year and also mandates price decreases for specific products. New products judged innovative or useful, that are
indicated for pediatric use, or that target orphan or small population diseases, however, may be eligible for a pricing premium. The Japanese government
has also promoted the use of generics, where available.

Fraud and Abuse and Related Regulatory Laws

We are subject to various federal and state laws pertaining to health care “fraud and abuse,” including both federal and state anti-kickback and false
claims laws. Outside of the U.S., we may be subject to analogous foreign laws and regulations in the various jurisdictions in which we operate. These laws
and regulations apply to our or our partners’ operations, sales and marketing practices, price reporting, and relationships with physicians and other
customers and third-party payors. Anti-kickback laws generally prohibit a manufacturer from soliciting, offering, receiving, or paying any remuneration to
generate business, including the purchase or prescription of a particular drug. Although the specific provisions of these laws vary, their scope is generally
broad and there may be no regulations, guidance or court decisions that clarify how the laws apply to particular industry practices. False claims laws
prohibit anyone from knowingly and willingly presenting, or causing to be presented, for payment to third party payors (including Medicare and Medicaid)
claims for reimbursement or services that are false or fraudulent, claims for items or services not provided as claimed, or claims for medically unnecessary
items or services.

In addition, we are subject to the federal physician sunshine act and certain similar physician payment and drug pricing transparency legislation in

various states. The sunshine provisions apply to manufacturers with products reimbursed under certain government programs and require those
manufacturers to disclose annually to the federal government certain payments made to physicians (defined to include doctors, dentists, optometrists,
podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment interests held by physicians (as defined above) and their
immediate family members. State laws may also require disclosure of pharmaceutical pricing information and marketing expenditures. Violations of the
physician sunshine act and similar legislation or the fraud and abuse laws may be punishable by civil or criminal sanctions, including fines and civil
monetary penalties, and future exclusion from participation in government healthcare programs.

Reimbursement and Healthcare Reform

In both domestic and foreign markets, sales and reimbursement of any approved products will depend, in part, on the extent to which the costs of
such products will be covered by third-party payors, such as government health programs, commercial insurance and managed healthcare organizations.
These third-party payors are increasingly challenging the prices charged for medical products and services and imposing controls to manage costs. The
containment of healthcare costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort.
Governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement, and
requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in
jurisdictions with existing controls and measures, could limit our net revenue and results. In addition, there is significant uncertainty regarding the
reimbursement status of newly approved healthcare products.

Adequate coverage and reimbursement in the U.S. and other markets is critical to the commercial success of approved products. Recently in the
U.S., there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in
several Congressional inquiries and proposed bills designed to, among other things, reform government program reimbursement methodologies. Individual
states in the U.S. have been increasingly active in passing legislation and implementing regulations designed to control pharmaceutical 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. Regional healthcare authorities and individual
hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription
drug and other healthcare programs. Third-party payors are increasingly challenging the prices charged for medical products and services and, in some
cases, imposing restrictions on the coverage of particular drugs. Many third-party payors negotiate the price of medical services and products and develop
formularies that establish pricing and reimbursement levels. Exclusion of a product from a formulary can lead to its sharply reduced usage in the third-party
payor’s patient population. The process for obtaining coverage can be lengthy and costly, and it could take several months before a particular payor initially
reviews a product and makes a decision with respect to coverage. For example, third-party payors may require cost-benefit analysis data in order to
demonstrate the cost-effectiveness of a particular product.

Outside the U.S., ensuring adequate coverage and payment for drug products can have challenges. Pricing of prescription pharmaceuticals is subject
to governmental control in many countries. Pricing negotiations with governmental authorities can extend well beyond the receipt of regulatory marketing
approval for a product and may require us to conduct an active comparator clinical trial to demonstrate the relative effectiveness of our therapeutic
candidates or products to other available therapies to support our pricing, which could be expensive and result in delays in our commercialization efforts.
Third-party payors are challenging the prices charged for medical products and services, and many third-party payors limit reimbursement for newly-
approved healthcare products. Recent budgetary pressures in many EU countries are also causing governments to consider or implement various cost-
containment measures, including reference price grouping, price freezes, increased price cuts, and rebates. If budget pressures continue, governments may
implement additional cost-containment measures. Cost-control initiatives could decrease the price we might establish for products that we may develop or
sell, which would result in lower product revenues or royalties payable to us. There can be no assurance that any country that has price controls or
reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our products.

The Patient Protection and Affordable Care Act (“PPACA”) made extensive changes to the delivery of healthcare in the U.S. The PPACA included

numerous provisions that affect pharmaceutical companies, some of which became effective immediately and others of which have taken effect over the
past several years. For example, the PPACA expanded healthcare coverage to the uninsured through private health insurance reforms and an expansion of
Medicaid. The PPACA also imposed substantial costs on pharmaceutical manufacturers, such as an increase in liability for rebates paid to Medicaid, new
drug discounts that must be offered to certain enrollees in the Medicare prescription drug benefit, an annual fee imposed on all manufacturers of brand
prescription drugs in the U.S., and an expansion of an existing program requiring pharmaceutical discounts to certain types of hospitals and federally
subsidized clinics. The PPACA also contains cost containment measures that could reduce reimbursement levels for healthcare items and services
generally, including pharmaceuticals. It also required reporting and public disclosure of payments and other transfers of value provided by pharmaceutical
companies to physicians and teaching hospitals.

The continuing efforts of the government, insurance companies, managed care organizations and other payors of healthcare services to contain or

reduce costs of healthcare could result in decreased net revenues from our pharmaceutical products and decreased potential returns from our development
efforts. In addition, pharmaceutical and device manufacturers are also required to report and disclose certain payments and transfers of value to, and
investment interests held by, physicians and their immediate family members during the preceding calendar year. Failure to submit required information
may result in civil monetary penalties for payments, transfers of value, or ownership or investment interests not reported in an annual submission.
Compliance with the PPACA and state laws with similar provisions is difficult and time consuming, and companies that do not comply with these state
laws face civil penalties.

In addition, there have been a number of other legislative and regulatory proposals aimed at changing the pharmaceutical industry. For example,

legislation has been enacted in certain states and at a federal level that requires development of an electronic pedigree to track and trace each prescription
drug at the saleable unit level through the distribution system. Compliance with these electronic pedigree requirements may increase our operational
expenses and impose significant administrative burdens.

Data Privacy and Security Laws

Pharmaceutical companies may be subject to U.S. federal and state health information privacy, security, and data breach notification laws, which
may govern the collection, use, disclosure, and protection of health-related and other personal information. State laws may be more stringent, broader in
scope, or offer greater individual rights with respect to protected health information (“PHI”), than the federal Health Insurance Portability and
Accountability Act of 1996, as amended, and its implementing regulations, which are collectively referred to as HIPAA, and state laws may differ from
each other, which may complicate compliance efforts. Entities that are found to be in violation of HIPAA or that enter into a resolution agreement with the
HHS to settle actual or potential allegations of HIPAA noncompliance may be subject to significant civil, criminal, and administrative fines and penalties
and/or additional reporting and oversight obligations.

Many state laws govern the privacy of personal information in specified circumstances. For example, in California the California Consumer Privacy

Act (“CCPA”), establishes a privacy framework for covered businesses by creating an expanded definition of personal information, establishing data
privacy rights for consumers in the State of California, imposing special rules on the collection of consumer data from minors, and creating a potentially
severe statutory damages framework for violations of the CCPA and for businesses that fail to implement reasonable security procedures and practices to
prevent data breaches. While clinical trial data and information governed by HIPAA are currently exempt from the CCPA, other personal information may
be covered, and possible changes to the CCPA may broaden its scope.

EU member states, the U.K., Switzerland, and other jurisdictions have also adopted data protection laws and regulations, which impose significant
compliance obligations. In the European Economic Area (“EEA”), the collection and use of personal data, including clinical trial data, is governed by the
provisions of the General Data Protection Regulation (“GDPR”). The GDPR, together with national legislation, regulations, and guidelines of the states in
the EEA, the U.K., and Switzerland governing the processing of personal data, impose strict obligations and restrictions on the ability to collect, analyze,
and transfer personal data, including health data from clinical trials and adverse event reporting. In particular, these obligations and restrictions concern the
consent of the individuals to whom the personal data relates, the information provided to the individuals, the transfer of personal data out of the EEA, the
U.K., or Switzerland, security breach notifications, security and confidentiality of the personal data, and imposition of substantial potential fines for
breaches of the data protection obligations. European data protection authorities may interpret the GDPR and national laws differently and impose
additional requirements, which add to the complexity of processing personal data in or from the EEA, the U.K., or Switzerland. Guidance on
implementation and compliance practices are often updated or otherwise revised.

Human Capital Resources

As of December 31, 2021, we had approximately 358 employees, of whom approximately 190 employees were engaged in the research and

development function of our operations. Our research and development staff, approximately 76 of whom hold Ph.D. or M.D. degrees, have diversified
experience in biochemistry, pharmacology, X-ray crystallography, synthetic organic chemistry, computational chemistry, medicinal chemistry, clinical
development, and regulatory affairs.

We believe that our ability to successfully execute on our strategic initiatives is highly dependent upon our ability to recruit, retain, and reward our
employees. We engage in targeted recruitment strategies to fill highly skilled positions. Our employees enjoy competitive salaries and benefits, as well as
equity participation. Our compensation philosophy is designed to provide an appealing, competitive, and rewarding compensation program that encourages
high personal and company performance, strong cultural and ethical behavior, and incentives aligned with stockholder interests.

We are committed to providing a workplace that protects the health and wellbeing of our employees. All employees are required to abide by our
Code of Conduct and Compliance Plan and health and safety parameters and to contribute to a positive, inclusive, and friendly company culture. Where we
believe such arrangements can be effective, we have implemented flexible working arrangements, including work from home arrangements, for our
employees, in part, to encourage employee health and wellness during the global COVID-19 pandemic. We consider our relations with our employees to be
satisfactory.

ITEM 1A.         RISK FACTORS

An investment in our stock involves risks. You should carefully read this entire report and consider the following uncertainties and risks, which may
adversely affect our business, financial condition or results of operations, along with all of the other information included in our other filings with the SEC,
before making an investment decision regarding our common stock.

Risks Relating to Our Business

Risks Relating to COVID-19

Our business, operations, clinical development or commercialization plans and timelines, and access to capital could be adversely affected by the
effects of the ongoing COVID-19 pandemic on us or on third parties with whom we conduct business, including without limitation our development
partners, manufacturers, clinical research organizations (“CROs”), and others, as well as on the regulatory and government agencies with whom we
work.

The global COVID-19 pandemic continues to affect the United States and global economies, and could cause disruptions to our business, operations,
and clinical development or commercialization plans and timelines, as well as the business and operations of third parties with whom we conduct business.
For example, government orders and evolving business policies and procedures have impacted and may continue to impact, among other things: (1) our
personnel and those of third parties on whom we rely, including our development partners (such as Torii), manufacturers, CROs, and others; (2) the conduct
of our current and future clinical trials and commercial interactions; and (3) the operations of the FDA, EMA, PMDA, and other health and governmental
authorities, which could result in delays of reviews and approvals.

If our operations or those of third parties with whom we conduct business are impaired or curtailed as a result of these events, the development and
commercialization of our products and product candidates could be stopped or delayed, or the costs of such development and commercialization activities
could increase, any of which could have a material adverse impact on our business. For example, our suppliers or other vendors may be unable to meet
their obligations to us or perform their services as expected as a result of the COVID-19 pandemic or other health epidemics. In such circumstances, we
may not be able to enter into arrangements with alternative suppliers or vendors or do so on commercially reasonable terms or in a timely manner. Such
delays could adversely impact our ability to meet our desired clinical development and any commercialization timelines. Although we carefully manage
our relationships with our suppliers and vendors, 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 an adverse impact on our business, financial condition and prospects.

20

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition, our clinical trials have been and may continue to be affected by the COVID-19 pandemic. For example, the acceleration of COVID-19
slowed startup of the inadequate C5 responder cohorts in our complement oral Factor D inhibitor program and, as a result, delayed the reporting of related
data in 2020. Clinical site initiation and patient enrollment may be delayed due to prioritization of hospital resources toward the COVID-19 pandemic or
concerns among patients about participating in clinical trials during a pandemic. Some patients may have difficulty following certain aspects of clinical trial
protocols if quarantines impede patient movement or interrupt healthcare services. Similarly, our inability to successfully recruit and retain patients and
principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 or experience additional restrictions by
their institutions, city, or state could adversely impact our clinical trial operations.

If global health concerns prevent the FDA, EMA, PMDA or other regulatory authorities from conducting their inspections, reviews, or other
regulatory activities, it could significantly impact the ability of such authorities to timely review and process our regulatory submissions, which could have
a material adverse effect on our business and clinical development and commercialization plans and timelines.

Although our business operations under the ongoing COVID-19 pandemic continue to evolve, where possible and practical, we continue to provide

work-from-home flexibility for our employees, which could negatively impact productivity, disrupt our business and delay our clinical programs and
timelines. In addition, we are a government contractor, and as such, we are subject to the federal COVID-19 safety protocols, including the vaccine
mandate.  We cannot accurately predict the impact on operations of our return-to-the-office plan, nor of the federal COVID-19 safety protocols on our
business or on third parties with whom we conduct business.  Our business may be negatively impacted in the event that large numbers of employees or
key employees do not comply with these protocols.  These and similar, and perhaps more severe, disruptions in our operations could negatively impact our
business, operating results and financial condition.

The spread of COVID-19, which has caused a broad impact globally, could also materially affect our access to capital. While the future economic

impact brought by, and the duration of, COVID-19 may be difficult to assess or predict, the pandemic could result in significant disruption of global
financial markets, reducing our ability to access the equity or debt capital markets or obtain other sources of capital, which could negatively affect our
liquidity. In addition, a recession or market correction resulting from the spread of COVID-19 and related responses could materially affect our business
and the value of our common stock.

The global pandemic of COVID-19 continues to evolve, with the ultimate impact of the COVID-19 pandemic or a similar health epidemic being

uncertain and subject to change. These effects could be material, and we will continue to monitor the COVID-19 situation closely. We do not yet know the
full extent and magnitude of the impacts that COVID-19 has had or will have on our business, on the healthcare system, or on the global economy. In
addition, the COVID-19 pandemic could have the effect of heightening many of the other risks described below.

Financial and Liquidity Risks

We have incurred losses since our inception, expect to continue to incur such losses, and may never be profitable.

Since our inception, we have not achieved sustained profitability. We expect to incur additional losses for the foreseeable future, and our losses could

increase as our research and development efforts and commercial activities progress. We expect that such losses will fluctuate from quarter to quarter and
that losses and fluctuations may be substantial. To become profitable, we, or our collaborative partners, must successfully manufacture and develop
products and product candidates, receive regulatory approval, and successfully commercialize our products and/or enter into profitable commercialization
arrangements with other parties. It could take longer than expected before we receive, or we may never receive, significant revenue from any current or
future license agreements or significant revenues directly from product sales. Even if we are able to successfully commercialize our existing products, or to
develop new commercially viable products, certain obligations we have to third parties, including, without limitation, our obligation to pay RPI and
OMERS, as applicable, royalties on certain revenues from ORLADEYO, BCX9930, and another earlier stage Factor D inhibitor under the Royalty
Purchase Agreements, may reduce the profitability of such products.

Because of the numerous risks and uncertainties associated with developing our product candidates, launching new products, and their potential for
commercialization, we are unable to predict the extent of any future losses. Even if we do achieve profitability, we may not be able to sustain or increase
profitability on a quarterly or annual basis. If we are unable to achieve and sustain profitability, the market value of our common stock will likely decline.

21

 
 
 
 
 
 
 
 
 
 
 
We may need to raise additional capital in the future. If we are unable to raise capital when needed, we may need to adjust our operations.

We have sustained operating losses for the majority of our corporate history and expect that our 2022 expenses will exceed our 2022 revenues. We

expect to continue to incur operating losses and negative cash flows unless and until revenues reach a level sufficient to support ongoing operations.

Our liquidity needs will be largely determined by the success of operations in regard to the commercialization of our products and the progression of
our product candidates in the future. Our plans for managing our liquidity needs primarily include controlling the timing and spending on our research and
development programs, raising additional funds through equity and/or debt financings, and commercializing our approved products. We regularly evaluate
other opportunities to fund operations including: (1) securing or increasing U.S. Government funding of our programs, including obtaining additional and
delivering on procurement contracts; (2) out-licensing rights to certain of our products or product candidates, pursuant to which we would receive cash
milestone payments and/or royalties; (3) raising additional capital through equity or debt financings or from other sources, including royalty or other
monetization transactions; (4) obtaining additional product candidate regulatory approvals, which would generate revenue, milestone payments and cash
flow; (5) reducing spending on research and development programs, including by discontinuing and suspending development; and/or (6) restructuring
operations to change our overhead structure.

There can be no assurance that any of our plans will be successful or that additional capital will be available to us on reasonable terms, or at all, when
needed. If we are unable to obtain sufficient additional capital, we may be forced to adjust or curtail our operations; delay, reduce, or stop ongoing clinical
trials or commercialization efforts; cease operations altogether; or file for bankruptcy.

Risks Relating to Drug Development and Commercialization

Our success depends upon our ability to advance our product candidates through the various stages of development, especially through the clinical
trial process, and to receive regulatory approval for the commercial sale of our product candidates.

To receive the regulatory approvals necessary for the commercial sale of our product candidates, we or our partners must demonstrate through
preclinical studies and clinical trials that each product candidate is safe and effective. The development process and related regulatory process are complex
and uncertain. The preclinical and clinical development of our product candidates is susceptible to the risk of failure inherent at any stage of drug
development, including failure to demonstrate efficacy and safety, the occurrence of adverse events that are severe or medically or commercially
unacceptable, our or our partners’ failure to comply with trial protocols, applicable regulatory requirements, and industry standards, or a determination by
the FDA or any comparable foreign regulatory authority that a product candidate may not continue development or be approved in accordance with our
development plans or at all. We cannot guarantee that any preclinical studies and clinical trials will be conducted as planned or completed on schedule, if at
all, or that the results of such trials will be sufficient to support regulatory approval for our product candidates.

Progression of our product candidates through the clinical development process is dependent upon our trials indicating that our product candidates

have adequate safety and efficacy in the patients being treated by achieving pre-determined safety and efficacy endpoints according to the clinical trial
protocols. Failure to achieve any of these endpoints in any of our programs, including our Factor D program (inclusive of BCX9930), BCX9250,
galidesivir, and our other rare disease product candidates, could result in delays in or modifications to our trials or require the performance of additional
unplanned trials. If any of our product candidates is associated with adverse events or undesirable side effects or has properties that are unexpected, we may
need to abandon development or limit development of that product candidate to certain uses or subpopulations in which the undesirable side effects or other
characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. Product candidates that initially show promise in clinical
or preclinical testing could later be found to cause undesirable or unexpected side effects that could result in delays in the development of our product
candidates, significant unexpected costs, or the termination of programs. The development plans for our product candidates, including our clinical trials,
may not be adequately designed or executed, which could negatively affect the outcome and analysis of study results. Because of the cost and duration of
clinical trials, we may decide to discontinue development of product candidates that are unlikely to show favorable results in clinical trials, unlikely to help
advance a product to the point of a meaningful collaboration, or unlikely to have reasonable commercial potential.

Undesirable or inconclusive data in our pre-clinical studies and clinical trials or side effects in humans could result in the FDA or foreign regulatory

authorities (including, e.g., the EMA, the MHLW or the MHRA) refusing to approve a product candidate for any targeted indications or imposing
restrictions or warnings that could impact development or the ultimate commercial viability of a product candidate. In addition, the FDA or foreign
regulatory authorities may determine that study data from our product candidates necessitates additional studies or study designs which differ from our
planned development strategy, and such regulatory authorities may also require patient monitoring and testing or may implement restrictions or other
conditions on our development activities, any of which could materially impact the cost and timing of our planned development strategy. We, our partners,
the FDA, or foreign regulatory authorities may suspend or terminate clinical trials at any time if we or they believe the trial participants face unacceptable
health risks.

Our ability to successfully complete the clinical development process is dependent upon many factors, including but not limited to:

● our or our partners’ ability to secure suitable clinical sites and investigators and to enroll and maintain an adequate number of patients on a

timely basis or at all;

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
● patients that enroll in a clinical trial may not comply with the clinical trial protocol or maintain contact with investigators to provide complete

data during and after treatment;

● our product candidates may not prove to be either safe or effective or may produce unfavorable or inconclusive results;
● we or our partners may decide, or be required by regulatory authorities, to suspend or terminate clinical research for various reasons,
including a finding that the participants are being exposed to unacceptable health risks, undesirable side effects or other unexpected
characteristics of the product candidate, noncompliance with regulatory requirements or their standards of conduct, or findings of undesirable
effects caused by a chemically or mechanistically similar product or product candidate;

● regulatory authorities may disagree with our or our partners’ clinical trial protocols or our or their interpretation of data from preclinical

studies and clinical trials;

● clinical protocols or study procedures may not be adequately designed or followed by the investigators;
● formulation improvements may not work as expected, which could negatively impact commercial demand for our product candidates;
● regulatory authorities may fail to approve or subsequently find fault with the manufacturing processes or facilities of third-party

manufacturers with which we or our partners enter into agreements for clinical and commercial supplies;

● the supply or quantity of raw materials or manufactured product candidates or other materials necessary to conduct development activities
may be insufficient, inadequate, or unavailable at an acceptable cost, and we or our partners may experience interruptions in supply;
● our or our partners’ development plans may be delayed or changed as a result of changes in development strategy, the impact of new or

different regulations, requirements, and guidelines, or other unexpected events or conditions;

● the cost of pre-clinical studies and clinical trials may be greater than we anticipate;
● we or our third-party contractors, including those manufacturing our product candidates or components or ingredients thereof, or conducting
clinical trials or laboratory testing on our or our partners’ behalf, may fail to comply with regulatory requirements and industry standards or
meet contractual obligations in a timely manner or at all; and

● the impact of the ongoing COVID-19 pandemic on one or more of the foregoing factors.

Clinical trials are lengthy and expensive. Many of the factors listed above could result in increased clinical development costs or longer clinical
development times for any of our programs. We or our partners incur substantial expense for, and devote significant time to, preclinical testing and clinical
trials, yet we cannot be certain that the tests and trials will ever result in the commercial sale of a product. Even if we or our partners successfully complete
clinical trials for our product candidates, we or our partners might not file the required regulatory submissions in a timely manner, may not receive
regulatory approval for the product candidates, in which case we would be unable to generate any revenues from product sales or licensing arrangements,
or any product candidate, if approved, may be subject to restrictions on labeling, marketing, distribution, prescribing, and use, which could adversely
impact the sales of such product.

If our development collaborations with third parties, such as our development partners, contractors and contract research organizations, fail, the
development of our product candidates will be delayed or stopped.

We rely heavily upon third parties for many important stages of our product candidate development, including but not limited to:

● discovery of natural proteins that cause or enable biological reactions necessary for the progression of the disease or disorder, called enzyme

targets;

● execution of certain pharmacology preclinical studies and late-stage development for our compounds and product candidates;
● management of our phase 1, 2 and 3 clinical trials, including medical monitoring, laboratory testing, and data management;
● execution of toxicology studies that may be required to obtain approval for our product candidates;
● formulation improvement strategies and methods;
● manufacturing the starting materials and drug substance required to formulate our products and the product candidates to be used in our

clinical trials, toxicology studies and any potential commercial product; and
● management of certain regulatory interactions outside of the United States.

Our failure to engage in successful collaborations at any one of these stages would greatly impact our business. If we do not license enzyme targets

or inhibitors from academic institutions or from other biotechnology companies on acceptable terms, our drug development efforts would suffer. Similarly,
if the contract research organizations or third-party contractors that conduct our initial or late-stage clinical trials, conduct our toxicology or other studies,
manufacture our starting materials, drug substance and product candidates, provide laboratory testing or other services in connection with our clinical trials,
or assist with our regulatory function breach their obligations to us, perform their services inconsistent with industry standards, or fail to comply with
regulatory requirements, this would delay or prevent both the development of our product candidates and the availability of any potential commercial
product.

If we lose our relationship with any one or more of these parties, we could experience a significant delay in both identifying another comparable

provider and then contracting for its services. We may be unable to retain an alternative provider on reasonable terms, if at all. Even if we locate an
alternative provider, it is likely that this provider may need additional time to respond to our needs and may not provide the same type or level of service as
the original provider. In addition, any provider that we retain will be subject to applicable FDA current Good Laboratory Practices, current Good
Manufacturing Practices (“cGMP”) and current Good Clinical Practices, and comparable foreign standards. We do not have control over compliance with
these regulations by these providers. Consequently, if these practices and standards are not adhered to by these providers, the development and
commercialization of our product candidates could be delayed. If any of the foregoing risks are realized, our business, financial condition and results of
operations could be materially adversely affected.

23

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If we fail to obtain additional financing or acceptable partnership arrangements, we may be unable to complete the development and
commercialization of our products and product candidates or continue operations.

As our programs advance, our costs are likely to increase. Our current and planned discovery, development, approval, and commercialization efforts
will require significant capital. Our expenses, revenues and cash utilization rate could vary significantly depending on many factors, including: our ability
to obtain regulatory approval for our product candidates, including BCX9930, BCX9250, and galidesivir; our ability to maintain regulatory approval for,
successfully commercialize, and achieve market acceptance of our products, including ORLADEYO; our ability to raise additional capital; the amount of
funding we receive from partnerships with third parties for the development and commercialization of our products and product candidates (including our
collaborations with Torii, BARDA/HHS, and NIAID/HHS); the commercial success of our products achieved by our partners; the amount or profitability of
any orders for peramivir or galidesivir by any government agency or other party; the progress and results of our current and proposed clinical trials for our
product candidates; and the progress made in the manufacture of our lead products and the progression of our other programs.

In order to continue future operations, progress our drug development programs, and commercialize our current products and product candidates, we
will be required to raise additional capital. In addition to seeking strategic partnerships, transactions and government funding, we may access the equity or
debt markets, incur additional borrowings, or seek other sources of funding to meet liquidity needs at any time, including to take advantage of attractive
opportunities in the capital markets. Additional funding, whether through additional sales of securities, additional borrowings, royalty or other monetization
transactions, collaborative arrangements with partners, including corporate partners such as Torii and governmental agencies such as BARDA/HHS or
NIAID/HHS, or from other sources, may not be available when needed or on terms acceptable to us. The issuance of preferred or common stock or
convertible securities, with terms and prices significantly more favorable than those of our currently outstanding common stock, could have the effect of
diluting or adversely affecting the holdings or rights of our existing stockholders. Additional borrowings may subject us to more restrictive covenants than
are currently applicable to us under our Credit Agreement. In addition, collaborative arrangements may require us to transfer certain material rights to such
corporate partners. Insufficient funds or lack of an acceptable partnership may require us to delay, scale-back or eliminate certain of our research and
development programs.

Our ability to raise additional capital when needed or at all may be limited and may greatly depend upon our success in commercializing and
achieving market acceptance of ORLADEYO and the success of our current drug development programs, including the progress, timeline and ultimate
outcome of the development programs (including but not limited to formulation progress, long-term human safety studies, and carcinogenicity, drug-drug
interaction, toxicity, or other required studies) for BCX9250 for the treatment of FOP, our Factor D program (including BCX9930) for diseases of the
complement system, our broad-spectrum antiviral program, including galidesivir, and other rare disease product candidates, as well as any post-approval
studies for our products. In addition, constriction and volatility in the equity and debt markets, including as a result of the impacts of COVID-19, may
restrict our future flexibility to raise capital when such needs arise. Furthermore, we have exposure to many different industries, financing partners and
counterparties, including commercial banks, investment banks and partners (which include investors, licensing partners, and the U.S. Government), which
may be unstable or may become unstable in the current economic and political environment, including as a result of the impacts of COVID-19. Any such
instability may impact these parties’ ability to fulfill contractual obligations to us, or it might limit or place burdensome conditions upon future transactions
with us. Also, it is possible that suppliers may be negatively impacted. Any such unfavorable outcomes in our current programs or unfavorable economic
conditions could place severe downward pressure on the price of our common stock and may decrease opportunities to raise capital in the capital or credit
markets, and further could reduce the return available on invested corporate cash, which, if severe and sustained, could have a material and adverse impact
on our results of operations and cash flows and limit our ability to continue development and commercialization of our products and product candidates.

If we or our partners do not obtain governmental approval for our product candidates or maintain governmental approval for our products, we or
our partners will not be able to commercialize and sell these products and potential products, which would significantly harm our business because
we will receive no revenue.

We or our partners must obtain regulatory approval before marketing or selling our products. If the FDA or a comparable foreign regulatory authority
delays or denies regulatory approval of one of our product candidates, or revokes approval of a previously approved product, we would be unable to market
or sell the product in the applicable jurisdiction and would not receive revenue from sales or licensing arrangements related thereto, which could have a
material and adverse impact on our business.

The process of preparing for and obtaining regulatory approval in any jurisdiction may be lengthy and expensive, and approval is never certain.

Because of the risks and uncertainties inherent to the development process, including risks and uncertainties related to the impact of COVID-19, our
product candidates could take a significantly longer time to gain regulatory approval than we expect or may never gain approval. As discussed under “Risk
Factors—Risks Relating to Our Business—Risks Relating to Drug Development and Commercialization—Our success depends upon our ability to advance
our product candidates through the various stages of development, especially through the clinical trial process, and to receive regulatory approval for the
commercial sale of our product candidates,” we or our partners may experience any number of unfavorable outcomes during or as a result of pre-clinical
studies and clinical trials that could delay or prevent regulatory approval of our product candidates, or negatively impact our management’s credibility, our
value and our operating results.

24

 
 
 
 
 
 
 
 
 
Even if the FDA or foreign regulatory authorities approve a product candidate, the approval may limit the indicated uses for a product candidate,

impose other restrictions on the product candidate, and/or may require post-approval studies that could impair the commercial viability of a product
candidate. Even upon any approval to market our potential products, whether in the United States or internationally, we will continue to be subject to
extensive regulatory requirements. These requirements are wide ranging and govern, among other things:

● adverse drug experience reporting regulations;
● product promotion;
● product manufacturing, including good manufacturing practice requirements; and
● product changes or modifications.

Our failure to comply with existing or future regulatory requirements for regulatory approval, or our loss of, or changes to, previously obtained

approvals, could impair our ability to generate any revenues from product sales or licensing arrangements, which could have a material adverse effect on
our business, financial condition, and results of operations.

We focus on rare diseases, which may create additional risks and challenges.

Because we focus on developing drugs as treatments for rare diseases, we may seek orphan drug, breakthrough therapy or fast track designations for

our product candidates in the United States or the equivalent designations elsewhere in the world. Often, regulatory authorities have broad discretion in
determining whether or not to grant such designations. We cannot guarantee that our product candidates will receive orphan drug status from the FDA or
equivalent designations from other regulatory authorities. We also cannot guarantee that we will receive breakthrough therapy, fast track, or equivalent
designations, which provide certain potential benefits such as more frequent meetings with the applicable regulatory authorities to discuss development
plans, intensive guidance on efficient drug development programs, and potential eligibility for rolling review or priority review. Even if we are successful
in obtaining any such designations for our product candidates, such designations may not lead to faster development or regulatory review or approval and
do not increase the likelihood that our product candidates will receive marketing approval. For instance, although BCX9930 for PNH has received Fast
Track and Orphan Drug designations from the FDA, we may not experience a faster development, review or approval process compared to the
conventional process in the relevant jurisdictions. We may not be able to obtain or maintain these designations for BCX9930 or other product candidates
that receive them, and our competitors may obtain these designations for their product candidates, which could impact our ability to develop and
commercialize our products and product candidates or compete with such competitors, which may adversely impact our business, financial condition or
results of operations.

The commercial viability of any approved product could be compromised if the product is less effective than expected, causes undesirable side effects
that were not previously identified, or fails to achieve market acceptance within the medical community.

If, after obtaining regulatory approval of a product, we or others discover that it is less effective than previously believed or causes undesirable side

effects that were not previously identified, any of the following adverse events could occur:

● regulatory authorities may withdraw their approval of, or impose marketing or manufacturing restrictions on, the product, or require us or our

partners to create a medication guide outlining the risks of unidentified side effects for distribution to patients;

● we or our partners may be required to recall the product, change the way the product is administered, conduct additional clinical trials, or be

subject to civil or criminal penalties; and

● the product may become less competitive and our reputation may suffer.

Even after receiving regulatory approval, any product could fail to gain sufficient, or even any, market acceptance by physicians, patients, third-party
payors, health authorities and others in the medical community. For example, physicians are often reluctant to switch their patients from existing therapies
even when new and potentially more effective or convenient treatments enter the market. Further, patients often acclimate to the therapy that they are
currently taking and do not want to switch unless their physicians recommend switching products or they are required to switch therapies due to lack of
reimbursement for existing therapies. If an approved product does not achieve an adequate level of market acceptance, it may not generate significant
revenues. The occurrence of any of the foregoing could have a material and adverse impact on our business.

25

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If we fail to successfully commercialize or establish collaborative relationships to commercialize certain of our products and product candidates, or
if any partner terminates or fails to perform its obligations under agreements with us, potential revenues from commercialization of our products
and product candidates could be reduced, delayed or eliminated.

Our business strategy includes increasing the asset value of our product and product candidate portfolio. We believe this is best achieved by retaining
full  product  rights  or  through  collaborative  arrangements  with  third  parties  as  appropriate.  As  needed,  potential  third-party  relationships  could  include
preclinical development, clinical development, regulatory approval, marketing, sales, and distribution of our products and product candidates.

Currently, we have established collaborative relationships, including with Torii for the commercialization of ORLADEYO in Japan and with each of

Shionogi and Green Cross for the development and commercialization of peramivir. The process of establishing and implementing collaborative
relationships is difficult, time-consuming and involves significant uncertainty, including:

● our partners may seek to renegotiate or terminate their relationships with us due to unsatisfactory commercial, regulatory or clinical results,

including post-approval clinical commitments, a change in business strategy, a change of control or other reasons;

● our contracts for collaborative arrangements may expire;
● the possibility that expiration or termination of collaborative relationships, such as those with certain of our distribution partners, may trigger

repurchase obligations of the Company for unsold product held by our partner;

● our partners may choose to pursue alternative technologies, including those of our competitors;
● we have had in the past, and in the future may have, disputes with a partner that could lead to litigation or arbitration, which could result in

substantial costs and divert the attention of our management;

● we do not have day-to-day control over the activities of our partners and have limited control over their decisions;
● our ability to generate future event payments and royalties from our partners depends upon their abilities to establish the safety and efficacy of
our product candidates, obtain regulatory approvals and achieve market acceptance of products developed from our product candidates;
● we or our partners may fail to properly initiate, maintain or defend our intellectual property rights, where applicable, or a party may utilize our
proprietary information in such a way as to invite litigation that could jeopardize or potentially invalidate our proprietary information or
expose us to potential liability;

● we or our partners may not devote sufficient capital or resources toward our products and product candidates; and
● we or our partners may not comply with applicable government regulatory requirements.

If we or our partners fail to fulfill our responsibilities in a timely manner, or at all, our development and commercialization efforts related to that

collaboration could be reduced, delayed or terminated, or it may be necessary for us to assume responsibility for activities that would otherwise have been
the responsibility of our partner. If we are unable to establish and maintain collaborative relationships on acceptable terms, we may have to delay or
discontinue further development or commercialization of one or more of our products or product candidates, undertake commercialization activities at our
own expense or find alternative sources of funding. Any delay in the development or commercialization of our products and product candidates would
severely affect our business, because if our product candidates do not progress through the development process or reach the market in a timely manner, or
at all, or if our products do not achieve market success, we may not receive any revenues from product sales or licensing arrangements.

The results of our partnership with Torii may not meet our current expectations.

We have an agreement with Torii for the development and commercialization of ORLADEYO in Japan. Our ability to realize the expected benefits of

this collaboration, including with respect to the receipt or amounts of royalty payments, is subject to a number of risks, including that the commercial
potential of ORLADEYO may not meet our current expectations, we or Torii may fail to comply with our respective obligations under the Torii Agreement,
and third parties may fail to perform their obligations to us on a timely basis or at all.

The Torii Agreement provides that we are entitled to receive tiered royalty payments, the amounts of which will depend upon the amount of annual

net sales of ORLADEYO in Japan during each calendar year and other factors. We remain responsible for regulatory activities with respect to
ORLADEYO in Japan for one year after the first commercial sale. We continue to use third parties to satisfy many of our obligations under the Torii
Agreement, including but not limited to our regulatory and other responsibilities in Japan. If our interactions, or those of our third-party agents, are
unsuccessful, we could fail to meet our obligations under the Torii Agreement, which could negatively impact the commercial success and the partnership,
impact the economic benefit expected or require additional development of ORLADEYO.

Torii may terminate the Torii Agreement under certain limited circumstances, including upon one year’s written notice after the sixth anniversary of
the first commercial sale of ORLADEYO in Japan. If the Torii Agreement is terminated in connection with these provisions, we will no longer be entitled
to receive any milestone or royalty payments thereunder, which could have a material adverse impact on our business and results of operations.

Torii has sole control over, and decision-making authority with respect to, commercialization activities for ORLADEYO for the prevention of HAE

attacks in Japan, subject to oversight from a joint steering committee. Therefore, our receipt, and the amounts, of any royalty payments under the Torii
Agreement are dependent upon Torii’s successful performance of such commercialization activities. In addition, competitive products and variations in
patient demand, prescription levels, reimbursement determinations or other factors may limit the commercial potential of ORLADEYO in Japan, which
could materially reduce the amount of any royalties we are entitled to receive under the Torii Agreement.

26

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Under the Torii Agreement, we are responsible for supplying Torii with its required amounts of ORLADEYO for commercial sale. If, due to the

failure of our third-party contract manufacturers to produce sufficient drug product, we fail to supply to Torii the required amounts of ORLADEYO, then
Torii’s ability to successfully commercialize ORLADEYO in Japan could be materially impaired, and we may receive less royalty income under the Torii
Agreement, or none at all.

Any  of  the  foregoing  risks  could  materially  adversely  impact  our  ability  to  perform  our  obligations  under  the  Torii  Agreement,  which  could

materially reduce the economic benefits of the Torii Agreement to us and impair or result in the termination of our collaboration with Torii.

There can be no assurance that our commercialization efforts, methods, and strategies for our products or technologies will succeed, and our future
revenue generation is uncertain.

There can be no assurance that our and our partners’ commercialization efforts, methods and strategies will succeed. We may be unable to establish

or sufficiently increase our sales, marketing and distribution capabilities for products we currently, or plan to, commercialize. Our ability to receive revenue
from products we or our partners commercialize is subject to several risks, including:

● we or our partners may fail to successfully complete clinical trials, or satisfy post-marketing commitments, sufficient to obtain and keep

regulatory agency marketing approval;

● many competitors are more experienced and have significantly more resources, and their products could reach the market faster, be more cost

effective or have a better efficacy or tolerability profile than our products and product candidates;

● we may fail to employ a comprehensive and effective intellectual property strategy, which could result in decreased commercial value of our
Company, our products and product candidates, or royalties associated with such products (e.g., the loss of the peramivir patent in Korea,
which may result in a reduced royalty from Green Cross);

● we may fail to employ a comprehensive and effective regulatory strategy, which could result in a delay or failure in commercialization of our

products;

● our and our partners’ ability to successfully commercialize our products is affected by the competitive landscape, which cannot be fully

known at this time;

● revenue from product sales would depend on our ability to obtain and maintain favorable pricing;
● reimbursement is constantly changing, which could greatly affect usage of our products;
● future revenue from product sales would depend on our ability to successfully complete clinical studies, obtain regulatory approvals, and

manufacture, market, distribute and commercialize our approved drugs; and

● the impact of the COVID-19 pandemic on us or our partners.

In addition, future revenue from sales of ORLADEYO is subject to uncertainties and will depend on several factors, including the success of our and
our partners’ commercialization efforts in the U.S. and elsewhere, the number of new patients switching to ORLADEYO, patient retention and demand, the
number of physicians prescribing ORLADEYO, the rate of monthly prescriptions, reimbursement from third-party payors, the conversion of patients from
our clinical trials and early access programs to commercial customers, and market trends.

Even if we are able to successfully commercialize our existing products, or to develop new commercially viable products, certain obligations we

have to third parties, including, without limitation, our obligations to pay royalties on certain revenues from ORLADEYO, BCX9930, and another earlier
stage Factor D inhibitor under the Royalty Purchase Agreements may reduce the profitability of such products.

We expect to continue expanding our development and regulatory capabilities and implementing sales, marketing and distribution capabilities, and
as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

We expect to continue experiencing significant growth in the number of our employees and the scope of our operations, particularly in the areas of

drug development, regulatory affairs, sales, marketing, and distribution. 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. For
example, we expanded our internal commercial team in 2020 in preparation for the commercial launch of ORLADEYO, and we continued to add additional
headcount throughout 2021. Due to our limited financial resources and the limited experience of our management team in managing a company with such
anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit, train, and retain additional qualified personnel.
The expansion of our operations may lead to significant costs and may divert our management and business development resources. In addition, if a
commercial launch for any product or product candidate for which we recruit a commercial team and establish marketing capabilities in any region is
delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. Any inability to manage
growth could delay the execution of our business plans or disrupt our operations.

27

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We depend on third-party vendors in the manufacture and distribution of our products, product candidates and the materials for our products and
product candidates. If we cannot rely on existing third-party vendors, we will be required to incur significant costs and potential delays in finding
new third-party vendors, which could adversely impact the development and commercialization timeframes for our products and product candidates.

We depend on third-party vendors, including third-party manufacturers, distributors, and specialty pharmacies, in the manufacture and distribution of

our products, product candidates, and the materials for our product candidates. Often, especially in the early development and commercialization process,
we have only one or limited sources for a particular product or service, such as manufacturing and/or distribution. We depend on these third-party vendors
to perform their obligations in a timely manner and in accordance with applicable governmental regulations. Our third-party vendors, particularly our third-
party manufacturers and distributors, which may be the only vendor we have engaged for a particular product or service or in a particular region, may
encounter difficulties with meeting our requirements, including but not limited to problems involving, as applicable:

● insufficient resources being devoted in the manner necessary to satisfy our requirements within expected timeframes;
● inconsistent production yields;
● product liability claims or recalls of commercial product;
● difficulties in scaling production to commercial and validation sizes;
● interruption of the delivery of materials required for the manufacturing process;
● failure to distribute commercial supplies of our products to commercial vendors or end users in a timely manner;
● scheduling of plant time with other vendors or unexpected equipment failure;
● potential catastrophes that could strike their facilities or have an effect on infrastructure;
● potential impurities in our drug substance or products that could affect availability of product for our clinical trials or future

commercialization;

● poor quality control and assurance or inadequate process controls;
● failure to provide us with accurate or timely information regarding inventories, the number of patients who are using our products, or serious

adverse events and/or product complaints regarding our products;

● inability of third parties to satisfy their financial obligations to us or to others;
● potential breach of the manufacturing or distribution agreement by the third party;
● possible termination or nonrenewal of a critical agreement by the third party at a time that is costly or inconvenient to us; and
● lack of compliance or cooperation with regulations and specifications or requests set forth by the FDA or other foreign regulatory agencies or
local customs, particularly associated with ORLADEYO, BCX9930, BCX9250, galidesivir, peramivir and our early-stage compounds.

Many additional factors could cause production or distribution interruptions with the manufacture and distribution of any of our products and product
candidates, including human error, natural disasters, pandemics, labor disputes, acts of terrorism or war, equipment malfunctions, or raw material shortages.
If our commercial distribution partners are not able to satisfy our requirements within the expected timeframe, or are unable to provide us with accurate or
timely information and data, including inventories and sales, serious adverse events, and/or product complaints, our business, including our commercial
launch and sales of ORLADEYO may be at risk. In addition, if specialty pharmacy services, including our third-party call center services, which provide
patient support and financial services, prescription intake and distribution, reimbursement adjudication, and ongoing compliance support, is not effectively
managed, the continuance of our commercial launch and sales of ORLADEYO may be delayed or compromised.

In addition, our contract manufacturers may not be able to manufacture the materials required for our products or product candidates at a cost or in

quantities necessary to make them commercially viable. Our raw materials, drug substances, products, and product candidates are manufactured by a
limited group of suppliers, including some at a single facility. If any of these suppliers were unable to produce these items, this could significantly impact
our supply of products and product candidate material for further preclinical testing and clinical trials. To date, our third-party manufacturers have met our
manufacturing requirements, but they may not continue to do so. Furthermore, changes in the manufacturing process or procedure, including a change in
the location where the drug is manufactured or a change of a third-party manufacturer, may require prior review and approval in accordance with the FDA’s
cGMP and comparable foreign requirements. This review may be costly and time-consuming and could delay or prevent the launch of a product. The FDA
or foreign regulatory authorities may at any time implement new standards, or change their interpretation and enforcement of existing standards, for
manufacture, packaging or testing of products. If we or our contract manufacturers are unable to comply, we or they may be subject to regulatory action,
civil actions or penalties, any of which could be costly to us and could result in a delay or shortage of product.

If we are unable to maintain current third-party relationships, or enter into new agreements with additional third parties on commercially reasonable
terms, or if there is poor manufacturing or distribution performance or failure to comply with any regulatory agency on the part of any of our third-party
vendors, we may not be able to complete development of, obtain timely approval of, or commercialize, our products and product candidates.

Commercialization of our products by us and our partners is subject to the potential commercialization risks described herein and numerous
additional risks. Any potential revenue benefits to us, including in the form of milestone payments, royalties or other consideration are highly
speculative.

Commercialization success of our products is uncertain and is subject to all the risks and uncertainties disclosed in our other risk factors relating to
drug development and commercialization. In addition, commercialization of our products is subject to further risks and may be negatively impacted by a
number of factors, including, but not limited to, the following:

● our products may not prove to be adequately safe and effective for market approval in markets other than the markets in which they are

currently approved;

● necessary funding for post-marketing commitments and further development of our products may not be available timely, at all, or in

sufficient amounts;

● advances in competing products could substantially replace potential demand for our products;
● government and third-party payors may not provide sufficient coverage or reimbursement, which would negatively impact the demand for our

products;

● we may not be able to supply commercial material to our partners and our partners may not be able to maintain or establish sufficient and

acceptable commercial manufacturing, either directly or through third-party manufacturers;

● the commercial demand and acceptance for our products by healthcare providers and by patients may not be sufficient to result in substantial

product revenues to us or to our partners and may result in little to no revenue, milestone payments, or royalties to us;

● effectiveness of marketing and commercialization efforts for our products by us or our partners;
● market satisfaction with existing alternative therapies;
● perceived efficacy relative to other available therapies;
● disease prevalence;
● cost of treatment;
● pricing and availability of alternative products;
● marketing and sales activities of competitors;
● shifts in the medical community to new treatment paradigms or standards of care; and
● relative convenience and ease of administration.

Risks Relating to Competing in Our Industry

We face intense competition, and if we are unable to compete effectively, the demand for our products may be reduced.

The biotechnology and pharmaceutical industries are highly competitive and subject to rapid and substantial technological change. There are many

companies seeking to develop products for the same indications that we currently target. Our competitors in the United States and elsewhere are numerous
and include, among others, major multinational pharmaceutical and chemical companies and specialized biotechnology firms. Most of these competitors
have greater resources than we do, including greater financial resources, larger research and development staffs and more experienced manufacturing,
marketing, and sales organizations. In addition, most of our competitors have greater experience than we do in conducting clinical trials and obtaining FDA
and other regulatory approvals. Accordingly, our competitors may succeed in obtaining FDA or other regulatory approvals of product candidates more
rapidly than we do or for products that compete with our products. Companies that complete clinical trials, obtain required regulatory approvals, and
commence commercial sale of their drugs before we do may achieve a significant competitive advantage, including patent and FDA exclusivity rights that
would delay our ability to market products. We face, and will continue to face, competition in the commercialization of our products, licensing of potential
product candidates for desirable disease targets, licensing of desirable product candidates, and development and marketing of our product candidates from
academic institutions, government agencies, research institutions and biotechnology and pharmaceutical companies. Competition may also arise from,
among other things:

● other drug development technologies;
● methods of preventing or reducing the incidence of disease, including vaccines; and
● new small molecule or other classes of therapeutic agents.

Developments by others may render our products, product candidates, or technologies obsolete or noncompetitive.

We received FDA approval of ORLADEYO, an oral, once-daily therapy for the prevention of HAE attacks in adults and pediatric patients 12 years

and older, in December 2020. We subsequently received regulatory approvals for ORLADEYO in Japan, the European Union, the United Kingdom, and the
United Arab Emirates in January 2021, April 2021, May 2021, and September 2021, respectively. In addition, we are performing research on or developing
products for the treatment of several other rare diseases, including diseases of the complement system and FOP, as well as developing broad spectrum
antivirals for use as medical countermeasures. We expect to encounter significant competition for our pharmaceutical products and product candidates.
Companies that complete clinical trials, obtain required funding or government support, obtain required regulatory approvals and commence commercial
sales or stockpiling orders of their products before their competitors may achieve a significant competitive advantage. There are licensed therapies for HAE
(including Berinert®, Haegarda®, Cinryze®, Kalbitor®, Takhzyro®, Firazyr® (icatibant), generic icatibant, and Ruconest®), therapies for certain
complement-mediated diseases such as PNH, aHUS, myasthenia gravis, and neuromyelitis optica spectrum disorder (Soliris®, Ultomiris®, and
Empaveli®), products for the prevention or treatment of influenza (seasonal flu vaccines, Tamiflu® (oseltamivir), generic oseltamivir, Relenza®, and
Inavir®, favipiravir, and Xofluza®), and a number of additional products in clinical development in these therapeutic areas and for the treatment of FOP. In
addition, various government entities throughout the world may offer incentives, grants and contracts to encourage additional investment into preventative
and therapeutic agents against viruses such as influenza, coronavirus, Ebola, and others, which may have the effect of further increasing the number of our
competitors and/or providing advantages to certain competitors. See “Business—Competition” in Part I, Item 1 of this report for further discussion of our
competitors, competitive products or programs, and the competitive conditions in these and other therapeutic areas.

29

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If one or more of our competitors’ products or programs, including potential competitors not currently identified, are successful, the market for our

products may be reduced or eliminated.

Compared to us, many of our competitors and potential competitors have substantially greater:

● capital resources;
● research and development resources, including personnel and technology;
● regulatory experience;
● preclinical study and clinical testing experience;
● manufacturing, marketing, and sales experience; and
● production facilities.

Any of these competitive factors could impede our funding efforts, render our products, product candidates, or technologies noncompetitive or eliminate

or reduce demand for our products and product candidates.

Legal and Regulatory Risks

We are subject to various laws and regulations related to our products and product candidates, and if we or our partners do not comply with these
laws and regulations, we could face substantial penalties.

Our or our partners’ activities related to approved products or, following their regulatory approval, any of our product candidates under development,

such as BCX9930, BCX9250, and galidesivir, are subject to regulatory and law enforcement authorities in the United States (including the FDA, the
Federal Trade Commission, the Department of Justice, and state and local governments) and their foreign equivalents (including the EMA, MHLW,
MHRA, and others).

We are responsible for reporting adverse drug experiences, have responsibility for certain post-approval studies, and may have responsibilities and

costs related to a recall or withdrawal of our products from sale in the jurisdictions in which they are approved. We may also incur liability associated with
product manufacturing contracted by us or in support of any of our partners. We are required to maintain records and provide data and reports to regulatory
agencies related to our products (e.g. risk evaluation and mitigation strategies, track and trace requirements, and adverse events), and we may incur certain
promotional regulatory and government pricing risks, all of which could have a material adverse impact on our operations and financial condition. Similar
responsibilities would apply upon regulatory approval of any of our other product candidates currently under development.

In addition, we are subject to the federal physician sunshine act and certain similar physician payment and drug pricing transparency legislation in

various states. We are also subject to various federal and state laws pertaining to health care “fraud and abuse,” including both federal and state anti-
kickback and false claims laws. Outside of the United States, we may be subject to analogous foreign laws and regulations in the various jurisdictions in
which we operate. These laws and regulations apply to our or our partners’ operations, sales and marketing practices, price reporting, and relationships with
physicians and other customers and third-party payors. Anti-kickback laws generally prohibit a manufacturer from soliciting, offering, receiving, or paying
any remuneration to generate business, including the purchase or prescription of a particular drug. Although the specific provisions of these laws vary, their
scope is generally broad and there may be no regulations, guidance or court decisions that clarify how the laws apply to particular industry practices. False
claims laws prohibit anyone from knowingly and willingly presenting, or causing to be presented, for payment to third party payors (including Medicare
and Medicaid) claims for reimbursement or services that are false or fraudulent, claims for items or services not provided as claimed, or claims for
medically unnecessary items or services. The sunshine provisions apply to manufacturers with products reimbursed under certain government programs
and require those manufacturers to disclose annually to the federal government certain payments made to physicians (defined to include doctors, dentists,
optometrists, podiatrists and chiropractors) and teaching hospitals, as well as, ownership and investment interests held by physicians (as defined above) and
their immediate family members. State laws may also require disclosure of pharmaceutical pricing information and marketing expenditures. Although we
seek to comply with these statutes, it is possible that our practices, or those of our partners, might be challenged under healthcare fraud and abuse, anti-
kickback, false claims or similar laws. Violations of the physician sunshine act and similar legislation or the fraud and abuse laws may be punishable by
civil or criminal sanctions, including fines and civil monetary penalties, and future exclusion from participation in government healthcare programs.

The 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 certain regulatory authorities,
including the FDA and comparable foreign regulatory authorities. Consequently, the FDA or other regulatory authority may conclude that a financial
relationship between us and a principal investigator creates a conflict of interest or otherwise affects interpretation of the study. In the event of a conflict of
interest with respect to a study, the integrity of the data generated at the applicable clinical trial site may be questioned or 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 or other regulatory authority, as the
case may be, and may ultimately lead to the denial of marketing approval of one or more of our product candidates.

30

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The FDA and foreign regulatory authorities may also impose post-approval commitments on us for approved products, which we may not complete
successfully or on time for any number of reasons, including but not limited to lack of funds to complete the studies and insufficient interest by appropriate
sites, investigators or study subjects. We are currently subject to certain post-approval commitments. If we fail to comply with post-approval legal and
regulatory requirements, we could be subject to penalties, and our products could be subject to continual recordkeeping and reporting requirements, review
and periodic inspections by the FDA and other regulatory bodies. Regulatory approval of a product may be subject to limitations on the indicated uses for
which the product may be marketed or to the other restrictive conditions of approval that limit our ability to promote, sell or distribute a product.
Furthermore, the approval of our products and any other future product candidates may be subject to requirements for costly post-approval testing and
surveillance to monitor its safety or efficacy.

Advertising and promotion are subject to stringent FDA rules and oversight, and as an NDA-holder, we may be held responsible for any advertising

and promotion that is not in compliance with the rules and regulations. In particular, the claims in all promotional materials and activities must be
consistent with the FDA approvals for approved products and must be appropriately substantiated and fairly balanced with information on the safety risks
and limitations of the products. We are also required to engage in appropriate truthful, non-misleading, and non-promotional scientific exchange concerning
our products, and applicable regulatory authorities, competitors, and other third parties may take the position that we are not in compliance with such
regulations. In addition to medical education efforts, we may offer patient support services to assist patients receiving treatment with our commercially
approved products which have increasingly become the focus of government investigation.

Adverse event information concerning approved products must be reviewed, and as an NDA-holder, we are required to make expedited and periodic
adverse event reports to the FDA and other regulatory authorities. In addition, the research, manufacturing, distribution, sale and promotion of products are
potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare and Medicaid
Services, other divisions of the U.S. Department of Health and Human Services, the U.S. Department of Justice and individual U.S. Attorney offices within
the Department of Justice, state and local governments, and foreign equivalents of the foregoing. All of these activities are also potentially subject to
healthcare false claims and fraud and abuse laws, as well as consumer protection and unfair competition laws.

If our operations with respect to our products that are subject to healthcare laws and regulations are found to be in violation of any of the healthcare
fraud and abuse laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including civil and criminal
penalties, damages, fines and the curtailment or restructuring of our operations. Any penalties, damages, fines, curtailment or restructuring of our
operations could adversely affect our ability to operate our business and our financial results. Although compliance programs can mitigate the risk of
investigation and prosecution for violations of these laws, the risks cannot be entirely eliminated. Any action against us for violation of these laws, even if
we successfully defend against it, could cause us to incur significant legal expenses and divert our management's attention from the operation of our
business. Moreover, achieving and sustaining compliance with all applicable fraud and abuse laws may be costly.

Our employees and consultants may engage in misconduct or other improper activities, including non-compliance with regulatory standards and
requirements, which could cause significant liability for us and harm our reputation.

We are subject to the risk of fraud or other misconduct by our employees and consultants, including intentional failures to comply with FDA
regulations or similar regulations of comparable foreign regulatory authorities, provide accurate information to the FDA or comparable foreign regulatory
authorities, comply with manufacturing standards we have established, comply with federal and state healthcare fraud and abuse laws and regulations and
similar laws and regulations established and enforced by comparable foreign regulatory authorities, report financial information or data accurately or
disclose unauthorized activities to us. Employee and consultant misconduct could also involve the improper use of information obtained in the course of
clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter employee and
consultant misconduct, whether intentional, reckless, negligent, or unintentional, 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 governmental investigations or other actions or lawsuits stemming
from a failure to be in compliance with such laws, standards or regulations. If any such actions are instituted against us and we are not successful in
defending ourselves or asserting our rights, those actions could have a significant impact on our business and results of operations, including the imposition
of significant fines or other sanctions.

We and our partners may be subject to new legislation, regulatory proposals and healthcare payor initiatives that may increase our costs of
compliance and adversely affect our or our partners’ ability to market our products, obtain collaborators and raise capital.

The Patient Protection and Affordable Care Act (“PPACA”), made extensive changes to the delivery of healthcare in the U.S. The PPACA included

numerous provisions that affect pharmaceutical companies, some of which became effective immediately and others of which have taken effect over the
past several years. For example, the PPACA expanded health care coverage to the uninsured through private health insurance reforms and an expansion of
Medicaid. The PPACA also imposed substantial costs on pharmaceutical manufacturers, such as an increase in liability for rebates paid to Medicaid, new
drug discounts that must be offered to certain enrollees in the Medicare prescription drug benefit, an annual fee imposed on all manufacturers of brand
prescription drugs in the U.S., and an expansion of an existing program requiring pharmaceutical discounts to certain types of hospitals and federally
subsidized clinics. The PPACA also contains cost containment measures that could reduce reimbursement levels for health care items and services
generally, including pharmaceuticals. It also required reporting and public disclosure of payments and other transfers of value provided by pharmaceutical
companies to physicians and teaching hospitals.

The continuing efforts of the government, insurance companies, managed care organizations and other payors of health care services to contain or
reduce costs of health care could result in decreased net revenues from our pharmaceutical products and decrease potential returns from our development
efforts. In addition, pharmaceutical and device manufacturers are also required to report and disclose certain payments and transfers of value to, and
investment interests held by, physicians and their immediate family members during the preceding calendar year. Failure to submit required information
may result in civil monetary penalties for payments, transfers of value, or ownership or investment interests not reported in an annual submission.
Compliance with the PPACA and state laws with similar provisions is difficult and time consuming, and companies that do not comply with these state
laws face civil penalties. Because of the breadth of these laws and the narrowness of the safe harbors, it is possible that some of our business activities
could be subject to challenge under one or more of such laws. Such a challenge could have a material adverse effect on our business, financial condition,
results of operations and growth prospects.

In addition, there have been a number of other legislative and regulatory proposals aimed at changing the pharmaceutical industry. For example,

legislation has been enacted in certain states and at a federal level that requires development of an electronic pedigree to track and trace each prescription
drug at the saleable unit level through the distribution system. Compliance with these electronic pedigree requirements may increase our operational
expenses and impose significant administrative burdens. In addition, our compliance may be deemed insufficient and we could face a material adverse
effect on our business, financial condition, results of operations and growth prospects. As a result of these and other new proposals, we may determine to
change our current manner of operation, provide additional benefits or change our contract arrangements, any of which could have a material adverse effect
on our business, financial condition and results of operations.

Adequate coverage and reimbursement in the U.S. and other markets is critical to the commercial success of our approved products. Recently in the

U.S., there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in
several Congressional inquiries and proposed bills designed to, among other things, reform government program reimbursement methodologies. Individual
states in the United States have been increasingly active in passing legislation and implementing regulations designed to control pharmaceutical 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. Regional health care authorities
and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their
prescription drug and other healthcare programs. Third-party payors are increasingly challenging the prices charged for medical products and services and,
in some cases, imposing restrictions on the coverage of particular drugs. Many third-party payors negotiate the price of medical services and products and
develop formularies which establish pricing and reimbursement levels. Exclusion of a product from a formulary can lead to its sharply reduced usage in the
third-party payor’s patient population. The process for obtaining coverage can be lengthy and costly, and we expect that it could take several months before
a particular payor initially reviews a product and makes a decision with respect to coverage. For example, third-party payors may require cost-benefit
analysis data from us in order to demonstrate the cost-effectiveness of our products or any other product we might bring to market. For any individual third-
party payor, we may not be able to provide data sufficient to gain reimbursement on a similar or preferred basis to competitive products, or at all, which
may have a material adverse effect on our business, financial condition and results of operations.

We are subject to data security and privacy risks, and our actual or perceived failure to comply with regulations and other legal obligations related
to privacy and data protection could harm our business.

We are subject to legal obligations related to privacy and data protection.  Compliance with U.S. and international data protection laws and
regulations 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. For example, we may be subject to the California Consumer Privacy Act, which gives California
residents expanded rights to access and require deletion of their personal information, opt out of certain personal information sharing, and receive detailed
information about how their personal information is used. We also may be subject to the General Data Protection Regulation in the EEA and similar
legislation in the U.K. and Switzerland.  See “Risks Relating to Our Business—Risks Relating to International Operations—Our actual or perceived failure
to comply with European governmental regulations and other legal obligations related to privacy, data protection and information security could harm our
business” in this section for additional discussion of international privacy laws and regulations. Failure to comply with these laws and regulations could
result in government enforcement actions, private litigation, or harm to our reputation and our business.

32

 
 
 
 
 
 
 
 
 
If because of our use of hazardous materials, we violate any environmental controls or regulations that apply to such materials, we may incur
substantial costs and expenses in our remediation efforts.

Our research and development involves the controlled use of hazardous materials, chemicals and various radioactive compounds. We are subject to

federal, state and local laws and regulations governing the use, storage, handling and disposal of these materials and some waste products. Accidental
contamination or injury from these materials could occur. In the event of an accident, we could be liable for any damages that result, and any liabilities
could exceed our resources. Compliance with environmental laws and regulations or a violation of such environmental laws and regulations could require
us to incur substantial unexpected costs, which would materially and adversely affect our results of operations.

Intellectual Property Risks

If we fail to adequately protect or enforce our intellectual property rights or secure rights to patents of others, the value of those rights would
diminish.

Our success will depend in part on our ability and the abilities of our partners to obtain, protect and enforce viable intellectual property rights
including but not limited to trade name, trademark and patent protection for our Company and its products, methods, processes and other technologies we
may license or develop, to preserve our trade secrets, and to operate without infringing the proprietary rights of third parties both domestically and abroad.
The patent position of biotechnology and pharmaceutical companies is generally highly uncertain, involves complex legal and factual questions and has
recently been the subject of much litigation. Neither the United States Patent and Trademark Office (“USPTO”), the Patent Cooperation Treaty offices, nor
the courts of the United States and other jurisdictions have consistent policies nor predictable rulings regarding the breadth of claims allowed or the degree
of protection afforded under many biotechnology and pharmaceutical patents. Further, we may not have worldwide patent protection for all of our product
candidates and our intellectual property rights may not be legally protected or enforceable in all countries throughout the world. In some jurisdictions, some
of our product candidates in certain programs, including our HAE program, may have short or no composition of matter patent life and we may therefore
rely on orphan drug exclusivity or data exclusivity. There can be no assurance that we will obtain orphan drug exclusivity or data exclusivity in every
jurisdiction. Further, in some jurisdictions, we may rely on formulation patents or method of use patents. Both the ability to achieve issuance and the
enforcement of formulation and method of use patents can be highly uncertain and can vary from jurisdiction to jurisdiction, and such patents may
therefore not adequately prevent competitors and potential infringers in some jurisdictions. The validity, scope, enforceability and commercial value of the
rights protected by such patents, therefore, is highly uncertain.

We also rely on trade secrets to protect technology in cases when we believe patent protection is not appropriate or obtainable. However, trade secrets
are difficult to protect. If we cannot maintain the confidentiality of our technology and other confidential information in connection with our collaborators
and advisors, our ability to receive patent protection or protect our proprietary information may be imperiled.

We may be involved in legal proceedings to protect or enforce our patents, the patents of our partners or our other intellectual property rights, which
could be expensive, time consuming and unsuccessful.

Competitors may infringe 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 unsuccessful. An adverse result
in any legal proceeding could put one or more of our patents at risk. Our success depends in part on avoiding the infringement of other parties’ patents and
other intellectual property rights as well as avoiding the breach of any licenses relating to our technologies and products. In the United States, patent
applications filed in recent years are confidential for 18 months, while older applications are not published until the patent issues. As a result, avoiding
patent infringement may be difficult and we may inadvertently infringe third-party patents or proprietary rights. These third parties could bring claims
against us, our partners or our licensors that even if resolved in our favor, could cause us to incur substantial expenses and, if resolved against us, could
additionally cause us to pay substantial damages. Further, if a patent infringement suit were brought against us, our partners or our licensors, we or they
could be forced to stop or delay research, development, manufacturing or sales of any infringing product in the country or countries covered by the patent
we infringe, unless we can obtain a license from the patent holder. Such a license may not be available on acceptable terms, or at all, particularly if the third
party is developing or marketing a product competitive with the infringing product. Even if we, our partners or our licensors were able to obtain a license,
the rights may be nonexclusive, which would give our competitors access to the same intellectual property.

33

 
 
 
 
 
 
 
 
 
 
If we or our partners are unable or fail to adequately initiate, protect, defend or enforce our intellectual property rights in any area of commercial
interest or in any part of the world where we wish to seek regulatory approval for our products, methods, processes and other technologies, the value of our
products and product candidates to produce revenue would diminish. Additionally, if our products, methods, processes, and other technologies or our
commercial use of such products, processes, and other technologies, including but not limited to any trade name, trademark or commercial strategy infringe
the proprietary rights of other parties, we could incur substantial costs. The USPTO and the patent offices of other jurisdictions have issued to us a number
of patents for our various inventions, and we have in-licensed several patents from various institutions. We have filed additional patent applications and
provisional patent applications with the USPTO. We have filed a number of corresponding foreign patent applications and intend to file additional foreign
and U.S. patent applications, as appropriate. We have also filed certain trademark and trade name applications worldwide. We cannot assure you as to:

● the degree and range of protection any patents will afford against competitors with similar products;
● if and when patents will issue;
● if patents do issue, we cannot be sure that we will be able to adequately defend such patents and whether or not we will be able to adequately

enforce such patents; or

● whether or not others will obtain patents claiming aspects similar to those covered by our patent applications.

If the USPTO or other foreign patent office upholds patents issued to others or if the USPTO grants patent applications filed by others, we may have

to:

● obtain licenses or redesign our products or processes to avoid infringement;
● stop using the subject matter claimed in those patents; or
● pay damages.

We may initiate, or others may bring against us, litigation or administrative proceedings related to intellectual property rights, including proceedings

before the USPTO or other foreign patent office. Any judgment adverse to us in any litigation or other proceeding arising in connection with a patent or
patent application could materially and adversely affect our business, financial condition and results of operations. In addition, the costs of any litigation or
administrative proceeding may be substantial whether or not we are successful.

Our success is also dependent upon the skills, knowledge and experience, none of which is patentable, of our scientific and technical personnel. To
help protect our rights, we require all employees, consultants, advisors and partners to enter into confidentiality agreements that prohibit the disclosure of
confidential information to anyone outside of our company and require disclosure and assignment to us of their ideas, developments, discoveries and
inventions. These agreements may not provide adequate protection for our trade secrets, know-how or other proprietary information in the event of any
unauthorized use or disclosure or the lawful development by others of such information, and if any of our proprietary information is disclosed, our business
will suffer because our revenues depend upon our ability to license or commercialize our products and product candidates and any such events would
significantly impair the value of such products and product candidates.

Product Liability Risks

We face an inherent risk of liability in the event that the use or misuse of our products or product candidates results in personal injury or death and
our product liability insurance coverage may be insufficient.

If the use or misuse of any products we sell, or a partner sells, harms people, we may be subject to costly and damaging product liability claims
brought against us by consumers, healthcare providers, pharmaceutical companies, third-party payors or others. The use of our product candidates in
clinical trials, including post-marketing clinical studies, could also expose us to product liability claims. We cannot predict all of the possible harms or side
effects that may result from the use of our products or the testing of product candidates, and therefore, the amount of insurance coverage we currently have
may not be adequate to cover all liabilities or defense costs we might incur. A product liability claim or series of claims brought against us could give rise
to a substantial liability that could exceed our resources. Even if claims are not successful, the costs of defending such claims and potential adverse
publicity could be harmful to our business.

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and will face even
greater risks upon any commercialization by us of our products or product candidates. We have product liability insurance covering our clinical trials.
Clinical trial and product liability insurance is becoming increasingly expensive. As a result, we may be unable to obtain sufficient insurance or increase
our existing coverage at a reasonable cost to protect us against losses that could have a material adverse effect on our business. An individual may bring a
product liability claim against us if one of our products or product candidates causes, or is claimed to have caused, an injury or is found to be unsuitable for
consumer use. Any product liability claim brought against us, with or without merit, could result in:

● liabilities that substantially exceed our product liability insurance, which we would then be required to pay from other sources, if available;
● an increase of our product liability insurance rates or the inability to maintain insurance coverage in the future on acceptable terms, or at all;
● withdrawal of clinical trial volunteers or patients;
● damage to our reputation and the reputation of our products, resulting in lower sales;
● regulatory investigations that could require costly recalls or product modifications;
● litigation costs; and
● the diversion of management’s attention from managing our business.

Risks Relating to Contractual Arrangements

We face risks related to our government-funded programs and are subject to various U.S. Government contract requirements, which may create a
disadvantage and additional risks to us.

We have contracts with BARDA/HHS and NIAID/HHS for the development of galidesivir as a treatment for diseases caused by RNA pathogens,

including Marburg virus disease, Yellow Fever and Ebola virus disease. In contracting with these government agencies, we are subject to various U.S.
Government contract requirements, including general clauses for a cost-reimbursement research and development contract, which may limit our
reimbursement or, if we are found to be in violation, could result in contract termination. If the U.S. Government terminates any of its contracts with us for
its convenience, or if we default by failing to perform in accordance with the contract schedule and terms, this could have an adverse impact on the
programs associated with such funding and could also adversely impact our cash flows and operations.

U.S. Government contracts typically contain a number of extraordinary provisions that would not typically be found in commercial contracts and

which may create a disadvantage and additional risks to us as compared to competitors that do not rely on U.S. Government contracts. These risks include
the ability of the U.S. Government to unilaterally:

● terminate or reduce the scope of our contract with or without cause;
● interpret relevant regulations (federal acquisition regulation clauses);
● require performance under circumstances which may not be favorable to us;
● require an in-process review where the U.S. Government will review the project and its options under the contract;
● control the timing and amount of funding, which impacts the development progress of our programs; and
● audit and object to our contract-related costs and fees, including allocated indirect costs.

The U.S. Government may terminate its contracts with us either for its convenience or if we default by failing to perform in accordance with the

contract schedule and terms. Termination for convenience provisions generally enable us to recover only our costs incurred or committed, and settlement
expenses and profit on the work completed prior to termination. Termination does not permit these recoveries under default provisions. In the event of
termination or upon expiration of a contract, the U.S. Government may dispute wind-down and termination costs and may question prior expenses under
the contract and deny payment of those expenses. Should we choose to challenge the U.S. Government for denying certain payments under a contract, such
a challenge could subject us to substantial additional expenses which we may or may not recover. Further, if the U.S. Government terminates its contracts
with us for its convenience, or if we default by failing to perform in accordance with the contract schedule and terms, this could have an adverse impact on
our cash flows and operations.

As a U.S. Government contractor, we are required to comply with applicable laws, regulations and standards relating to our accounting practices and
are subject to periodic audits and reviews. As part of any such audit or review, the U.S. Government may review the adequacy of, and our compliance with,
our internal control systems and policies, including those relating to our purchasing, property, estimating, compensation and management information
systems. Audits under the active BARDA/HHS and NIAID/HHS galidesivir contracts may occur at the election of the U.S. Government and have been
concluded through fiscal 2019; all subsequent fiscal years are still open and auditable. Based on the results of its audits, the U.S. Government may adjust
our contract-related costs and fees, including allocated indirect costs. This adjustment could impact the amount of revenues reported on a historic basis and
could impact our cash flows under the contracts prospectively. In addition, in the event BARDA/HHS or NIAID/HHS determines that certain costs and fees
were unallowable or determines that the allocated indirect cost rate was higher than the actual indirect cost rate, BARDA/HHS or NIAID/HHS would be
entitled to recoup any overpayment from us as a result. In addition, if an audit or review uncovers any improper or illegal activity, we may be subject to
civil and criminal penalties and administrative sanctions, including termination of our contracts, forfeiture of profits, suspension of payments, fines and
suspension or prohibition from doing business with the U.S. Government. We could also suffer serious harm to our reputation if allegations of impropriety
were made against us. In addition, under U.S. Government purchasing regulations, some of our costs may not be reimbursable or allowed under our
contracts. Further, as a U.S. Government contractor, we are subject to an increased risk of investigations, criminal prosecution, civil fraud, whistleblower
lawsuits and other legal actions and liabilities as compared to private sector commercial companies.

There are risks related to the potential government use or sale of our antivirals.

Government use or sale, in emergency situations or otherwise, of our antivirals (including peramivir for the treatment of influenza) may result in

risks to us or our collaborative partners. There can be no assurance that government use of our antivirals (whether as indicated or outside of their current
indications) will prove to be generally safe, well-tolerated and effective. Any government sale or use (on an emergency basis or otherwise) of our antivirals
in any country may create liabilities for us or our partners.

In September 2018, we entered into a contract with the U.S. Government for the procurement of up to 50,000 doses of RAPIVAB (peramivir
injection) over a five-year period. In addition, we are working with NIAID/HHS to further develop galidesivir. There can be no assurance that we or our
manufacturers will be able to fully meet the demand for such antivirals with respect to these or future arrangements. Further, we may not receive a
favorable purchase price for future orders, if any, of our antivirals by governmental entities. Our competitors may develop products that could compete with
or replace any antivirals selected for government sale or use. We may face competition in markets where we have no existing intellectual property
protection or are unable to successfully enforce our intellectual property rights.

35

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
There can be no assurance that the non-U.S. partnerships that we have entered into for peramivir will result in any order for peramivir in those
countries or that peramivir will be approved for any use or will achieve market approval in additional countries. There can be no assurance that galidesivir
will be approved for use in any countries. In the event that any emergency use or market approval is granted in any country, there can be no assurance that
any government order or commercialization of the applicable product or product candidate in such countries will be substantial or will be profitable to us.

If we fail to reach milestones or to make annual minimum payments or otherwise breach our obligations under our license agreements, our
licensors may terminate our agreements with them and seek additional remedies.

If we are unable or fail to meet payment obligations, performance milestones relating to the timing of regulatory filings, product supply obligations,

post-approval commitments, or development and commercial diligence obligations; are unable or fail to make milestone payments or material data use
payments in accordance with applicable provisions; or fail to pay the minimum annual payments under any of our in-licenses relating to our products or
product candidates, our licensors may terminate the applicable license or seek other available remedies. As a result, our development of the respective
product candidate or commercialization of the product would cease.

Royalties and milestone payments, if any, from Shionogi under the Shionogi Agreement are required to be used by Royalty Sub to satisfy its
obligations under its PhaRMA Notes, and generally will not be available to us for other purposes unless and until Royalty Sub has repaid in full its
obligations under the PhaRMA Notes.

In March 2011, our wholly-owned subsidiary, Royalty Sub, issued $30.0 million in aggregate principal amount of PhaRMA Notes. The PhaRMA
Notes are secured principally by (i) certain royalty and milestone payments under the Shionogi Agreement, pursuant to which Shionogi licensed from us
the rights to market peramivir in Japan and Taiwan and (ii) the pledge by us of our equity interest in Royalty Sub. Payments, if any, from Shionogi to us on
non-governmental sales under the Shionogi Agreement will generally not be available to us for other purposes unless and until Royalty Sub has repaid in
full its obligations under the PhaRMA Notes. Accordingly, these funds have been and will continue to be required to be dedicated to Royalty Sub’s debt
service and not available to us for product development or other purposes. Since September 1, 2014, payments from Shionogi have been insufficient for
Royalty Sub to service its obligations under the PhaRMA Notes, resulting in a continuing event of default with respect to the PhaRMA Notes since that
time. As a result of the continuing event of default, the holders of the PhaRMA Notes may be able to foreclose on the collateral securing the PhaRMA
Notes and our equity interest in Royalty Sub and may exercise other remedies available to them under the indenture or other documents related to the
PhaRMA Notes. In such event, we may not realize the benefit of future royalty payments, if any, that might otherwise accrue to us following repayment of
the PhaRMA Notes, we may incur legal costs, and we might otherwise be adversely affected.

The PhaRMA Notes had a final legal maturity date of December 1, 2020, at which time the outstanding principal amount of the PhaRMA Notes of

$30.0 million, together with accrued and unpaid interest of $20.6 million, was due in full. The failure by Royalty Sub to repay in full the outstanding
principal amount of the PhaRMA Notes, together with any accrued and unpaid interest, at the December 1, 2020 final maturity date constituted an
additional event of default under the PhaRMA Notes. We cannot predict whether holders of PhaRMA Notes will seek to pursue any remedies as a result of
the continuing events of default with respect to the PhaRMA Notes. The PhaRMA Notes are the obligation of Royalty Sub. As a result, we do not currently
expect the continuing events of default on the PhaRMA Notes to have a significant impact on our future results of operations or cash flows. However, we
cannot assure you that this will be the case or that we will not otherwise be adversely affected as a result the continuing events of default under the
PhaRMA Notes or the failure by Royalty Sub to repay the PhaRMA Notes at maturity.

We wrote off the balance due under the PhaRMA Notes to other income as a debt extinguishment as of December 31, 2021.  See “Note 8−Royalty
Monetizations−RAPIACTA−Non-Recourse Notes Payable−Debt Extinguishment” in the Notes to Consolidated Financial Statements in Part II, Item 8 of
this report for additional information about the write-off.

Because continuing events of default exist under the PhaRMA Notes, the holders of the PhaRMA Notes may be able to foreclose on the collateral
securing the PhaRMA Notes and our equity interest in Royalty Sub. As a result, we may not realize the benefit of future royalty payments, if any,
that might otherwise accrue to us following repayment of the PhaRMA Notes and we could otherwise be adversely affected.

As Royalty Sub has been unable to service its obligations under the PhaRMA Notes and continuing events of default exist under the PhaRMA Notes,

the holders of the PhaRMA Notes may be able to foreclose on the collateral securing the PhaRMA Notes and our equity interest in Royalty Sub and may
exercise other remedies available to them under the indenture or other documents related to the PhaRMA Notes. In such event, we may not realize the
benefit of future royalty payments, if any, that might otherwise accrue to us following repayment of the PhaRMA Notes, we may incur legal costs, and we
might otherwise be adversely affected. In addition, the PhaRMA Notes had a final legal maturity date of December 1, 2020, at which time the outstanding
principal amount of the PhaRMA Notes of $30.0 million, together with accrued and unpaid interest of $20.6 million, was due in full. The failure by
Royalty Sub to repay in full the outstanding principal amount of the PhaRMA Notes, together with any accrued and unpaid interest, at the December 1,
2020 final maturity date constituted an additional event of default under the PhaRMA Notes. We cannot predict whether holders of PhaRMA Notes will
seek to pursue any remedies as a result of the continuing events of default with respect to the PhaRMA Notes. The PhaRMA Notes are the obligation of
Royalty Sub. As a result, we do not currently expect the continuing events of default on the PhaRMA Notes to have a significant impact on our future
results of operations or cash flows. However, we cannot assure you that this will be the case or that we will not otherwise be adversely affected as a result
the continuing events of default under the PhaRMA Notes or the failure by Royalty Sub to repay the PhaRMA Notes at maturity.

We wrote off the balance due under the PhaRMA Notes to other income as a debt extinguishment as of December 31, 2021. See “Note 8−Royalty
Monetizations−RAPIACTA−Non-Recourse Notes Payable−Debt Extinguishment” in the Notes to Consolidated Financial Statements in Part II, Item 8 of
this report for additional information about the write-off.

We have incurred significant indebtedness, which could adversely affect our business. Additionally, our Credit Agreement contains conditions and
restrictions that limit our flexibility in operating our business. We may be required to make a prepayment or repay our outstanding indebtedness
earlier than we expect if a prepayment event or an event of default occurs, including a material adverse change with respect to us, which could have
a material adverse effect on our business.

As of December 31, 2021, we had an outstanding principal balance under our Credit Agreement of $142.1 million, inclusive of the quarterly PIK
Interest Payments. We have also committed to draw another $75.0 million in aggregate principal amount under the Term B Loan and the Term C Loan
(each as defined in the Credit Agreement) under the Credit Agreement. If we do not draw these Term Loans by the end of the applicable period available to
draw them, we will be required to pay to Athyrium, for the account of the lenders, a make-whole premium plus certain fees set forth in the Credit
Agreement, subject to certain exceptions set forth in the Credit Agreement. We will also be required to pay to Athyrium, for the account of the lenders, a
make-whole premium plus certain fees set forth in the Credit Agreement in the event that we either (x) terminate the commitments in respect of the Term B
Loan or the Term C Loan on or prior to the end of the applicable period available to draw such Term Loans, or (y) prepay or repay, or are required to
prepay or repay, voluntarily or pursuant to a mandatory prepayment obligation under the Credit Agreement (e.g., with the proceeds of certain asset sales,
certain ORLADEYO out-licensing or royalty monetization transactions (excluding the Royalty Sales), extraordinary receipts, debt issuances, or upon a
change of control of the Company and specified other events, subject to certain exceptions), all of the then-outstanding Term Loans under the Credit
Agreement, in each case, subject to certain exceptions set forth in the Credit Agreement.

Our indebtedness could have important consequences to our stockholders. For example, it:

● increases our vulnerability to adverse general economic or industry conditions;
● limits our flexibility in planning for, or reacting to, changes in our business or the industry in which we operate;
● makes us more vulnerable to increases in interest rates, as borrowings under our Credit Agreement are at variable rates;
● requires us to dedicate a portion of our cash flow from operations to interest payments, limiting the availability of cash for other purposes;
● limits our ability to obtain additional financing or refinancing in the future for working capital or other purposes; and
● places us at a competitive disadvantage compared to our competitors that have less indebtedness.

Furthermore, our Credit Agreement contains various covenants that limit our ability to engage in specified types of transactions. Subject to certain
exceptions, these covenants limit our ability to, among other things, grant certain types of liens on our assets; make certain investments; incur or assume
certain debt, including accessing additional tranches of debt under the Credit Agreement; engage in certain mergers, acquisitions, and similar transactions;
dispose of assets; license certain property; distribute dividends; make certain restricted payments; change the nature of our business; engage in transactions
with affiliates and insiders; prepay other indebtedness; or engage in sale and leaseback transactions.

The Credit Agreement also contains certain financial covenants, including a minimum liquidity covenant that requires us to maintain at all times, as

applicable, at least $15.0 million of unrestricted cash and cash equivalents if only the Term A Loan (as defined in the Credit Agreement) has been drawn; at
least $20.0 million of unrestricted cash and cash equivalents if the Term B Loan has been drawn but the Term C Loan has not been drawn; and at least
$15.0 million (or, in certain circumstances, $20.0 million) of unrestricted cash and cash equivalents if the Term C Loan has been drawn, subject to certain
exceptions. In addition, when we draw upon the Term C Loan, we will be required to achieve certain minimum targets for consolidated net revenues from
ORLADEYO sales in the U.S.

The covenants contained in the Credit Agreement could cause us to be unable to pursue business opportunities that we or our stockholders may

consider beneficial without the lenders’ permission or without repaying all outstanding obligations under the Credit Agreement.

A breach of any of these covenants could result in an event of default under the Credit Agreement. An event of default will also occur if, among

other things, we fail to pay amounts due under the Credit Agreement, we fail to repay certain other indebtedness having an aggregate principal amount in
excess of one percent of our borrowings under the Credit Agreement, a material adverse change in our business, assets, properties, liabilities, or condition
occurs, or a material impairment of our ability to perform our obligations under the Credit Agreement occurs, we experience a change of control, certain
negative regulatory events occur, including without limitation the loss of a required permit or a recall of a product, or we fail to make required payments
under our Royalty Purchase Agreements. In the case of a continuing event of default under the Credit Agreement, the lenders under the Credit Agreement
could elect to declare all amounts outstanding to be immediately due and payable, proceed against the collateral in which we granted to the lenders a
security interest, or otherwise exercise the rights of a secured creditor. Amounts outstanding under the Credit Agreement are secured by a security interest
in, subject to certain exceptions, substantially all of our assets. Because substantially all of our assets are pledged to secure the Credit Agreement
obligations, our ability to incur additional secured indebtedness or to sell or dispose of assets to raise capital may be impaired, which could have an adverse
effect on our financial flexibility.

Risks Relating to International Operations

International expansion of our business exposes us to business, regulatory, political, operational, financial, and economic risks.

Our  business  strategy  includes  international  expansion,  including  the  commercialization  of  products  outside  of  the  United  States.  We  currently
conduct clinical studies and regulatory activities and have hired, and expect to continue hiring, employees outside of the United States. Doing business
internationally involves a number of risks, including but not limited to:

● multiple, conflicting, and changing laws and regulations such as privacy and data regulations, transparency regulations, tax laws, export and

import restrictions, employment laws, regulatory requirements, and other governmental approvals, permits, and licenses;

● introduction of new health authority requirements and/or changes in health authority expectations;
● failure by us or our partners to obtain and maintain regulatory approvals for the use of our products in various countries;
● complexities and difficulties in obtaining and maintaining protection for, and enforcing, our intellectual property;
● difficulties in staffing and managing foreign operations;
● complexities associated with managing multiple payor reimbursement regimes, government payors, or patient self-pay systems;
● limits on our ability to penetrate international markets;
● financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the impact of local and regional financial crises on

demand and payment for our products, and exposure to foreign currency exchange rate fluctuations;

● natural disasters and political and economic instability, including wars, terrorism, political unrest, results of certain elections and votes, actual
or threatened public health emergencies and outbreak of disease (including for example, the recent coronavirus outbreak), boycotts, adoption
or expansion of government trade restrictions, and other business restrictions;

● certain expenses including, among others, expenses for travel, translation, and insurance;
● regulatory and compliance risks that relate to maintaining accurate information and control over commercial operations and activities that

may fall within the purview of the U.S. Foreign Corrupt Practices Act, including its books and records provisions or anti-bribery provisions,
or the U.K. Bribery Act and similar foreign laws and regulations; and

● regulatory and compliance risks relating to doing business with any entity that is subject to sanctions administered by the Office of Foreign

Assets Control of the U.S. Department of the Treasury.

Any of these factors could significantly harm our future international expansion of operations and, consequently, our business and results of

operations.

Additionally, in some countries, such as Japan and the countries of the EU, the pricing of prescription pharmaceuticals is subject to governmental
control and access. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval
for a product. To obtain reimbursement or pricing approval in some countries, we or our partners may be required to conduct a clinical trial that compares
the cost-effectiveness of our product to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if
pricing is set at unsatisfactory levels, our business could be materially harmed.

Our actual or perceived failure to comply with European governmental regulations and other legal obligations related to privacy, data protection
and information security could harm our business.

EU member states, the U.K., Switzerland and other countries have adopted data protection laws and regulations, which impose significant
compliance obligations. For example, the General Data Protection Regulation (“GDPR”) imposes strict requirements on controllers and processors of
personal data, including special protections for “special category data,” which includes health, biometric and genetic information of data subjects located in
the EEA and, through incorporation in national legislation, the U.K. Further, the GDPR provides a broad right for EU member states to create supplemental
national laws, for example relating to the processing of health, genetic and biometric data, which could further limit our ability to use and share such data
or could cause our costs to increase and harm our business and financial condition. The GDPR and similar national legislation grant individuals the
opportunity to object to the processing of their personal information, allows them to request deletion of personal information in certain circumstances, and
provides the individual with an express right to seek legal remedies in the event the individual believes his or her rights have been violated. Further, the
GDPR and similar national legislation impose strict rules on the transfer of personal data out of the EEA, the U.K., Switzerland, and other countries to the
United States or other regions that have not been deemed to offer “adequate” privacy protections.

38

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Failure to comply with the requirements of the GDPR or related national data protection laws, which may deviate from the GDPR, may result in

significant fines of up to 4% of global revenues, or €20.0 million, whichever is greater, and in addition to such fines, our failure to comply with the
requirements of GDPR or similar national legislation may subject us to litigation and/or adverse publicity, which could have material adverse effects on our
reputation and business. As a result of the implementation of the GDPR, we are required to put in place additional mechanisms to ensure compliance with
the new data protection rules. For example, the GDPR requires us to make more detailed disclosures to data subjects, requires disclosure of the legal basis
on which we can process personal data, makes it harder for us to obtain valid consent for processing, will require the appointment of a data protection
officer where sensitive personal data (i.e., health data) is processed on a large scale, introduces mandatory data breach notification throughout the EU,
imposes additional obligations on us when we are contracting with service providers and requires us to adopt appropriate privacy governance including
policies, procedures, training and data audit.

We are subject to the supervision of local data protection authorities in those jurisdictions where we undertake clinical trials. We depend on a number

of third parties in relation to the provision of our services, a number of which process personal data of EU individuals on our behalf. With each such
provider we are required to enter into contractual arrangements under which they are contractually obligated to only process personal data according to our
instructions, and conduct diligence to ensure that they have sufficient technical and organizational security measures in place.

We are also subject to evolving European privacy laws on electronic marketing and cookies. The EU is in the process of replacing the e-Privacy
Directive (2002/58/EC) with a new set of rules taking the form of a regulation that will be directly implemented in the laws of each EU member state.
While this e-Privacy Regulation was originally intended to be adopted on May 25, 2018, it is still going through the European legislative process and the
timing of its adoption remains unclear.

The United Kingdom’s decision to withdraw from the EU could result in increased regulatory and legal complexity, which may make it more
difficult for us to do business in Europe and impose additional challenges in securing regulatory approval of our product candidates in Europe.

The United Kingdom’s exit from the EU, or Brexit, has caused political and economic uncertainty, including in the regulatory framework applicable

to our operations and product candidates, and this uncertainty may persist for years. Brexit could, among other outcomes, disrupt the free movement of
goods, services and people between the United Kingdom and the EU, and result in increased legal and regulatory complexities, as well as potential higher
costs of conducting business in Europe. The long-term effects of Brexit will depend in part on how the current and future trade agreements between the
United Kingdom and the EU take effect in practice. Changes in United Kingdom or EU regulations may cause disruption or delays in granting clinical trial
authorization or opinions for marketing authorization, disruption of importation and export of active substance and other components of new drug
formulations, and disruption of the supply chain for clinical trial product and final authorized formulations.

The cumulative effects of the disruption to the regulatory framework may add considerably to the development lead time to marketing authorization

and commercialization of products in the EU and/or the United Kingdom. It is possible that there will be increased regulatory complexities, which can
disrupt the timing of our clinical trials and regulatory approvals. In addition, changes in, and legal uncertainty with regard to, national and international
laws and regulations may present difficulties for our clinical and regulatory strategy. Any delay in obtaining, or an inability to obtain, any marketing
approvals, as a result of Brexit or otherwise, would prevent us from commercializing our product candidates in the United Kingdom and/or the EU and
restrict our ability to generate revenues and achieve and sustain profitability.

In addition, as a result of Brexit, other European countries may seek to conduct referenda with respect to their continuing membership with the EU.

Given these possibilities and others we may not anticipate, as well as the absence of comparable precedent, it is unclear what financial, regulatory and legal
implications the withdrawal of the United Kingdom from the EU will have and how such withdrawal will affect us, and the full extent to which our
business could be adversely affected.

Risks Relating to Technology

If our facilities, or the facilities of our third-party vendors, incur damage or power is lost for a significant length of time, our business will suffer.

We and our third-party vendors store commercial product, clinical and stability samples at our facilities that could be damaged if the facilities incur
physical damage or in the event of an extended power failure. We have backup power systems in addition to backup generators to maintain power to all
critical functions, but any loss of these products or samples could result in significant delays in our commercialization or drug development process.

In  addition,  we  store  most  of  our  preclinical  and  clinical  data  at  our  facilities.  Duplicate  copies  of  most  critical  data  are  secured  off-site.  Any
significant degradation or failure of our computer systems could cause us to inaccurately calculate or lose our data. Loss of data could result in significant
delays in our drug development process and any system failure could harm our business and operations.

39

 
 
 
 
 
 
 
 
 
 
 
 
 
A significant disruption in our information technology systems or a cybersecurity breach could adversely affect our business.

We are increasingly dependent on information technology systems to operate our business. In addition, the FDA and comparable foreign regulatory
authorities regulate, among other things, the record keeping and storage of data pertaining to potential pharmaceutical products. We currently store most of
our preclinical research data, our clinical data and our manufacturing data at our facilities. While we do store duplicate copies of most of our clinical data
offsite and a significant portion of our data is included in regular backups of our systems, we could lose important data if our facilities incur damage, or if
our vendor data systems fail, suffer damage or are destroyed.

Like other companies in our industry, our networks and infrastructure may be vulnerable to cyber-attacks or intrusions, including by computer
hackers, foreign governments, foreign companies, or competitors, or may be breached by employee error, malfeasance or other disruption. A breakdown,
invasion, corruption, destruction, or interruption of critical information technology systems could negatively impact operations. If our systems are
damaged, fail to function properly or otherwise become unavailable, we may incur substantial costs to repair or replace them, and we may experience loss
of critical data and interruptions or delays in our ability to perform critical functions, which could adversely affect our business, financial condition or
results of operations. Any compromise of our data security could also result in a violation of applicable privacy and other laws, significant legal and
financial exposure, damage to our reputation, loss or misuse of the information and a loss of confidence in our data security measures, which could harm
our business. There can be no assurance that our efforts to protect our data and information technology systems will prevent breakdowns or breaches in our
systems, or those of third parties with which we do business, and any such events could adversely affect our business.

Risks Relating to Investing in Our Common Stock

Our existing principal stockholders hold a substantial amount of our common stock and may be able to influence significant corporate decisions,
which may conflict with the interest of other stockholders.

Several of our stockholders own greater than 5% of our outstanding common stock. Our top ten stockholders own close to 50% of our common stock

and can individually, and as a group, influence our operations based upon their concentrated ownership and may also be able to influence the outcome of
matters requiring approval of the stockholders, including the election of our directors and other corporate actions.

Our stock price has been, and is likely to continue to be, highly volatile, which could cause the value of an investment in our common stock to
decline significantly.

The market prices for securities of biotechnology companies in general have been highly volatile and may continue to be highly volatile in the future.

Moreover, our stock price has fluctuated frequently, and these fluctuations are often not related to our financial results. For the twelve months ended
December 31, 2021, the 52-week range of the market price of our stock was from $7.27 to $18.48 per share. The following factors, in addition to other risk
factors described in this section, may have a significant impact on the market price of our common stock:

● announcements of technological innovations or new products by us or our competitors;
● developments or disputes concerning patents or proprietary rights;
● additional dilution through sales of our common stock or other derivative securities;
● status of new or existing licensing or collaborative agreements and government contracts;
● announcements relating to the status of our programs;
● developments and announcements regarding new and virulent strains of influenza;
● we or our partners achieving or failing to achieve development milestones;
● publicity regarding actual or potential medical results relating to products under development by us or our competitors;
● publicity regarding certain public health concerns for which we are or may be developing treatments;
● regulatory developments in both the United States and foreign countries;
● public concern as to the safety of pharmaceutical products;
● actual or anticipated fluctuations in our operating results;
● changes in financial estimates or recommendations by securities analysts;
● changes in the structure of healthcare payment systems, including developments in price control legislation;
● announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments;
● additions or departures of key personnel or members of our board of directors;
● purchases or sales of substantial amounts of our stock by existing stockholders, including officers or directors;
● economic and other external factors or other disasters or crises; and
● period-to-period fluctuations in our financial results.

Future sales and issuances of securities may dilute the ownership interests of our current stockholders and cause our stock price to decline.

Future sales of our common stock by us or our current stockholders into the public market could cause the market price of our stock to fall. As of

January 31, 2022, there were 184,661,799 shares of our common stock outstanding. We may from time to time issue securities in relation to a license
arrangement, collaboration, merger or acquisition. We may also sell, for our own account, shares of common stock or other equity securities, from time to
time at prices and on terms to be determined at the time of sale.

As of January 31, 2022, there were 30,321,597 stock options and restricted stock units outstanding and 3,683,617 shares available for issuance under

our Amended and Restated Stock Incentive Plan, 4,624,409 stock options and restricted stock units outstanding and 672,882 shares available for issuance
under our Amended and Restated Inducement Equity Incentive Plan, and 5,937,390 shares available for issuance under our Amended and Restated
Employee Stock Purchase Plan. In addition, we could also make equity grants outside of our Amended and Restated Stock Incentive Plan or Amended and
Restated Inducement Equity Incentive Plan. The shares underlying existing stock options, restricted stock units and possible future stock options, stock
appreciation rights and stock awards have been registered pursuant to registration statements on Form S-8.

If some or all of such shares are sold or otherwise issued into the public market over a short period of time, our current stockholders’ ownership
interests may be diluted and the value of all publicly traded shares is likely to decline, as the market may not be able to absorb those shares at then-current
market prices. Additionally, such sales and issuances may make it more difficult for us to sell equity securities or equity-related securities in the future at a
time and price that our management deems acceptable, or at all.

In March 2017, we entered into a Registration Rights Agreement with entities affiliated with Baker Bros. Advisors LP (the “Baker Entities”) to
provide that, if requested, we will register the shares of our common stock beneficially owned by the Baker Entities for resale under the Securities Act. Our
registration obligations pursuant to the Registration Rights Agreement cover all shares then held or thereafter acquired by the Baker Entities, for up to ten
years, and include our obligation to facilitate certain underwritten public offerings of our common stock by the Baker Entities in the future. On May 10,
2017, we filed a registration statement on Form S-3 with respect to 11,710,951 shares of common stock held by the Baker Entities. Subsequently, on
November 21, 2019, certain of the Baker Entities acquired pre-funded warrants to purchase 11,764,706 shares of our common stock at a price of $1.69 per
warrant. In addition, on June 1, 2020, we issued to certain of the Baker Entities pre-funded warrants to purchase 3,511,111 shares of our common stock at a
price of $4.49 per warrant. Each warrant has an exercise price of $0.01 per share. If the Baker Entities, by exercising their underwriting rights or otherwise,
sell a large number of our shares, or the market perceives that the Baker Entities intend to sell a large number of our shares, this could adversely affect the
market price of our common stock.

We have anti-takeover provisions in our corporate charter documents that may result in outcomes with which you do not agree.

Our  board  of  directors  has  the  authority  to  issue  up  to  5,000,000  shares  of  undesignated  preferred  stock  and  to  determine  the  rights,  preferences,
privileges and restrictions of those shares without further vote or action by our stockholders. The rights of the holders of any preferred stock that may be
issued in the future may adversely affect the rights of the holders of common stock. The issuance of preferred stock could make it more difficult for third
parties to acquire a majority of our outstanding voting stock.

In addition, our Certificate of Incorporation provides for staggered terms for the members of the board of directors and supermajority approval of the
removal  of  any  member  of  the  board  of  directors  and  prevents  our  stockholders  from  acting  by  written  consent.  Our  Certificate  of  Incorporation  also
requires  supermajority  approval  of  any  amendment  of  these  provisions.  These  provisions  and  other  provisions  of  our  bylaws  and  of  Delaware  law
applicable to us could delay or make more difficult a merger, tender offer or proxy contest involving us.

We have never paid dividends on our common stock and do not anticipate doing so in the foreseeable future.

We have never paid cash dividends on our stock. We currently intend to retain all future earnings, if any, for use in the operation of our business.

Accordingly, we do not anticipate paying cash dividends on our common stock in the foreseeable future.

Our Amended and Restated Bylaws provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for certain
litigation that may be initiated by our stockholders, which may limit a stockholder’s ability to obtain a favorable judicial forum for such disputes
with us or our directors, officers or employees.

Our Amended and Restated Bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the

State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of
breach of a fiduciary duty owed by any of our directors, officers, stockholders, employees or agents to us or our stockholders, (iii) any action asserting a
claim against us or any of our directors, officers, stockholders, employees or agents arising out of or relating to any provision of the General Corporation
Law of Delaware or our Certificate of Incorporation or Amended and Restated Bylaws or (iv) any action against us or any of our directors, officers,
stockholders, employees or agents governed by the internal affairs doctrine of the State of Delaware. This exclusive forum provision does not apply to
establish the Delaware Court of Chancery as the forum for actions or proceedings brought to enforce a duty or liability created by the Securities Act of
1933, as amended, or the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction.

This exclusive forum provision may limit a stockholder’s ability to choose its preferred judicial forum for disputes with us or our directors, officers,

employees or agents, which may discourage the filing of lawsuits with respect to such claims. If a court were to find this exclusive forum provision to be
inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in another jurisdiction, which could
adversely affect our business and financial condition.

General Risk Factors

Natural disasters, epidemic or pandemic disease outbreaks, trade wars, political unrest or other events could disrupt our business or operations or
those of our development partners, manufacturers, regulators or other third parties with whom we conduct business now or in the future.

A wide variety of events beyond our control, including natural disasters, epidemic or pandemic disease outbreaks (such as the ongoing COVID-19

pandemic), trade wars, political unrest or other events could disrupt our business or operations or those of our development partners (such as Torii),
manufacturers, regulatory authorities, or other third parties with whom we conduct business. These events may cause businesses and government agencies
to be shut down, supply chains to be interrupted, slowed, or rendered inoperable, and individuals to become ill, quarantined, or otherwise unable to work
and/or travel due to health reasons or governmental restrictions. If our operations or those of third parties with whom we have business are impaired or
curtailed as a result of these events, the development and commercialization of our products and product candidates could be impaired or halted, which
could have a material adverse impact on our business. See “Risk Factors—Risks Relating to Our Business—Risks Relating to COVID-19(cid:0)Our business,
operations, clinical development or commercialization plans and timelines, and access to capital could be adversely affected by the effects of the ongoing
COVID-19 pandemic on us or on third parties with whom we conduct business, including without limitation our development partners, manufacturers,
clinical research organizations (“CROs”), and others, as well as on the regulatory and government agencies with whom we work.” In addition, other events,
such as the armed conflict between Russia and Ukraine, could adversely impact our business.  Furthermore,  the conflict could lead to sanctions,
embargoes, supply shortages, regional instability, geopolitical shifts, cyberattacks, other retaliatory actions, and adverse effects on macroeconomic
conditions, currency exchange rates, and financial markets, which could adversely impact our operations and financial results, as well as those of third
parties with whom we conduct business.

We are subject to legal proceedings, which could harm our reputation or result in other losses or unexpected expenditure of time and resources.

From time to time, we may be involved in disputes, including, without limitation, disputes with our employees, collaborative partners, and third-

party vendors. We may be called upon to initiate legal proceedings or to defend ourselves in such legal proceedings relating to our relationships with these
parties, our decisions and actions or omissions with respect thereto, and our business. In addition, if our stock price is volatile, we may become involved in
securities class action lawsuits in the future. Due to the inherent uncertainties in legal proceedings, we cannot accurately predict the ultimate outcome of
any such proceedings. An unfavorable outcome in any such proceedings could have an adverse impact on our business, financial condition and results of
operations. Any current or future dispute resolution or legal proceeding, regardless of the merits of any such proceeding, could harm our reputation and
result in substantial costs and a diversion of management’s attention and resources that are needed to successfully run our business.

Insurance coverage is increasingly more costly and difficult to obtain or maintain.

While we currently have insurance for our business, property, directors and officers, and our products, insurance is increasingly more costly and

narrower in scope, and we may be required to assume more risk in the future. If we are subject to claims or suffer a loss or damage in excess of our
insurance coverage, we will be required to bear any loss in excess of our insurance limits. If we are subject to claims or suffer a loss or damage that is
outside of our insurance coverage, we may incur significant uninsured costs associated with loss or damage that could have an adverse effect on our
operations and financial position. Furthermore, any claims made on our insurance policies may impact our ability to obtain or maintain insurance coverage
at reasonable costs or at all.

If we fail to retain our existing key personnel or fail to attract and retain additional key personnel, the development of our product candidates, the
commercialization of our products, and the related expansion of our business will be delayed or stopped.

We are highly dependent upon our senior management and scientific team, the unexpected loss of whose services might impede the achievement of

our development and commercial objectives. This risk has been heightened in the current environment as a result of the ongoing COVID-19 pandemic.
Competition for key personnel with the experience that we require is intense and is expected to continue to increase. Our inability to attract and retain the
required number of skilled and experienced management, commercial, operational and scientific personnel will harm our business because we rely upon
these personnel for many critical functions of our business.

ITEM 7.         MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management’s Discussion and Analysis (“MD&A”) is intended to help the reader understand our results of operations and financial
condition. MD&A is provided as a supplement to, and should be read in conjunction with, our audited financial statements and the accompanying notes to
the  financial  statements  and  other  disclosures  included  in  this  report  (including  the  “Cautionary  Note  Regarding  Forward-Looking  Statements”  at  the
beginning of this report and the “Risk Factors” section in Part I, Item 1A of this report).

Overview

We are a commercial-stage biotechnology company that discovers novel, oral, small-molecule medicines. We focus on oral treatments for rare

diseases in which significant unmet medical needs exist and an enzyme plays the key role in the biological pathway of the disease. We integrate the
disciplines of biology, crystallography, medicinal chemistry, and computer modeling to discover and develop small molecule pharmaceuticals through the
process known as structure-guided drug design. In addition to these discovery and development efforts, our business strategy includes the efficient
commercialization of these drugs in the U.S. and certain other regions upon regulatory approval. By focusing on rare disease markets, we believe that we
can more effectively control the costs of, and our strategic allocation of financial resources toward, post-approval commercialization.

Our marketed products include oral, once-daily ORLADEYO® for the prevention of hereditary angioedema (“HAE”) attacks and RAPIVAB®
(peramivir injection) for the treatment of acute uncomplicated influenza in the United States.  ORLADEYO received regulatory approval in the United
States in December 2020.  During 2021, ORLADEYO received regulatory approvals in the European Union, Japan, the United Arab Emirates, and the
United Kingdom.  We are commercializing ORLADEYO in each of these territories directly or through distributors, except in Japan where Torii, our
collaborative partner, has the exclusive right to commercialize ORLADEYO for the prevention of HAE attacks in exchange for certain milestone and
royalty payments to us.  In addition to its approval in the United States, peramivir injection has received regulatory approvals in Canada, Australia, Japan,
Taiwan and Korea. 

Our revenues are difficult to predict and depend on several factors, including those discussed in the “Risk Factors” section in Part I, Item 1A of this

report. For example, our revenues depend, in part, on regulatory approval decisions for our products and product candidates, the effectiveness of our and
our collaborative partners’ commercialization efforts, market acceptance of our products, particularly ORLADEYO, the resources dedicated to our products
by us and our collaborative partners, and ongoing discussions with government agencies regarding contract awards for development and procurement, as
well as entering into, or modifying, licensing agreements for our product candidates. Furthermore, revenues related to our collaborative development
activities are dependent upon the progress toward and the achievement of developmental milestones by us or our collaborative partners.

Our operating expenses are also difficult to predict and depend on several factors, including research and development expenses (and whether these
expenses are reimbursable under government contracts), drug manufacturing, and clinical research activities, the ongoing requirements of our development
programs, the costs of commercialization, the availability of capital and direction from regulatory agencies, which are difficult to predict, and the factors
discussed in the “Risk Factors” section in Part I, Item 1A of this report. Management may be able to control the timing and level of research and
development and selling, general and administrative expenses, but many of these expenditures will occur irrespective of our actions due to contractually
committed activities and/or payments.

As a result of these factors, we believe that period-to-period comparisons are not necessarily meaningful, and you should not rely on them as an
indication of future performance. Due to the foregoing factors, it is possible that our operating results will be below the expectations of market analysts and
investors. In such event, the prevailing market price of our common stock could be materially adversely affected.

Critical Accounting Policies and Estimates

The accompanying discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements
and the related disclosures, which have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires
us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and
liabilities. We evaluate our estimates, judgments and the policies underlying these estimates on a periodic basis, as situations change, and regularly discuss
financial events, policies, and issues with members of our audit committee and our independent registered public accounting firm. In particular, we
routinely evaluate our estimates and policies regarding revenue recognition, administration, inventory and manufacturing, taxes, stock-based compensation,
research and development, consulting and other expenses and any associated liabilities. Our estimates are based on historical experience and on various
other assumptions that are believed to be reasonable under the circumstances. The results of our estimates form the basis for making judgments about the
carrying values of assets and liabilities that are not readily apparent from other sources. See “Critical Accounting Policies” at the end of this
“Management’s Discussion and Analysis of Financial Condition and Results of Operations” for a description of accounting policies that we believe are the
most critical to aid you in fully understanding and evaluating our reported financial results and that affect the more significant judgments and estimates that
we use in the preparation of our financial statements.

Recent Corporate Highlights

COVID-19

The outbreak of COVID-19 has severely impacted global economic activity and caused significant volatility in financial markets. To date, our
financial condition, results of operations, and liquidity have not been materially impacted by the direct effects of the COVID-19 pandemic. Please refer to
“Risk Factors(cid:0)Risks Relating to Our Business(cid:0)Risks Relating to COVID-19” in Part I, Item 1A of this report for a discussion of COVID-19 risks as they
relate to our business. We are continuing to monitor developments with respect to the COVID-19 pandemic and to make adjustments as needed to assist in
protecting the safety of our employees and communities while continuing our business activities. Our remote working arrangements continue to be flexible
where it is both practical and possible for the business. Business-related travel has increased, and we will continue to monitor developments with respect to
COVID-19 going forward. To date, implementation of specific COVID-19 measures has not required material expenditures or significantly impacted our
ability to operate our business or our internal control over financial reporting and disclosure controls and procedures. We continue to monitor the potential
impacts of COVID-19 on our operations and those of our partners, suppliers, customers, and regulators.

ORLADEYO (berotralstat)

ORLADEYO is an oral, once-daily therapy discovered and developed by us for the prevention of HAE attacks. Approved first by the FDA in the

U.S. in December 2020, ORLADEYO is also approved in the European Union, Japan, the United Kingdom, and the United Arab Emirates for the
prevention of HAE attacks in adults and pediatric patients 12 years and older.

On January 10, 2022, we announced that ORLADEYO is now covered by all major payors and national and regional pharmacy benefit managers in

the U.S.

We built out our U.S. commercial infrastructure in 2020 to support the launch of ORLADEYO in the U.S. and are continuing to build our
commercial infrastructure to support launches in Europe and elsewhere.  Based on proprietary analyses of HAE prevalence and market research studies
with HAE patients, physicians, and payors in the U.S. and Europe, and our first full year of experience with the ORLADEYO launch in 2021, we anticipate
the commercial market for ORLADEYO has the potential to reach a global peak of more than $1 billion in annual sales.  We expect at least 70 to 80
percent of our revenue at peak to come from the U.S.  These expectations are subject to numerous risks and uncertainties that may cause our actual results,
performance, or achievements to be materially different.  There can be no assurance that our commercialization methods and strategies will succeed, or that
the market for ORLADEYO will develop in line with our current expectations.  See “Risk Factors(cid:0)Risks Relating to Our Business(cid:0)Risks Relating to Drug
Development and Commercialization(cid:0)There can be no assurance that our commercialization efforts, methods, and strategies for our products or
technologies will succeed, and our future revenue generation is uncertain” in Part I, Item 1A of this report for further discussion of these risks.

Revenue from sales of ORLADEYO in 2021, which was our first full year of ORLADEYO sales, is discussed under “Results of Operations.”

Revenue from sales of ORLADEYO in future periods is subject to uncertainties and will depend on several factors, including the success of our and our
partners’ commercialization efforts in the U.S. and elsewhere, the number of new patients switching to ORLADEYO, patient retention and demand, the
number of physicians prescribing ORLADEYO, the rate of monthly prescriptions, reimbursement from third-party and government payors, the conversion
of patients from our clinical trials and early access programs to commercial customers, and market trends. We are continuing to monitor and analyze this
data as we continue to commercialize ORLADEYO.

Complement-Mediated Diseases

BCX9930 is a novel, oral, potent, and selective small molecule inhibitor of Factor D discovered by the Company and currently in clinical

development for the treatment of complement-mediated diseases. Based on the safety and proof-of-concept (“PoC”) data generated to date in patients with
PNH, the program has advanced to pivotal studies of oral BCX9930 (500 mg twice-daily) in PNH and to a proof-of-concept trial of oral BCX9930 (500 mg
twice-daily) in renal complement-mediated diseases. We are working closely with key opinion leaders in hematology and nephrology to map the advanced
development strategy across a broad set of indications. Our goal is to develop BCX9930 as a monotherapy for complement-mediated diseases.

On November 29, 2021, we announced the enrollment of the first patient in the REDEEM-2 pivotal trial with BCX9930 in patients with PNH.
REDEEM-2 is a randomized, placebo-controlled trial evaluating the efficacy and safety of BCX9930 (500 mg twice-daily) as monotherapy versus placebo
in PNH patients not currently receiving complement inhibitor therapy. In part 1 of this trial, patients will be randomized 2:1 to receive BCX9930 or placebo
under double-blind conditions for 12 weeks. All patients will receive BCX9930 in part 2 (weeks 13-52) to assess the long-term safety, tolerability, and
effectiveness of BCX9930, with patients randomized to placebo in part 1 switching to BCX9930 at the week 12 visit. The primary endpoint of REDEEM-2
is change from baseline in hemoglobin, as assessed at week 12.

On January 7, 2022, we announced the enrollment of the first patient in the REDEEM-1 pivotal trial with BCX9930 in patients with PNH.
REDEEM-1 is a randomized, open-label, active comparator-controlled comparison of the efficacy and safety of BCX9930 (500 mg twice-daily)
monotherapy in PNH patients with an inadequate response to a C5 inhibitor. In part 1 of this trial, patients who have not had an adequate response to a C5
inhibitor will be randomized 2:1 to discontinue their C5 inhibitor and receive BCX9930 as monotherapy or to continue receiving their C5 inhibitor for 24
weeks. All patients will receive BCX9930 in part 2 (weeks 25-52) to assess the long-term safety, tolerability, and effectiveness of BCX9930. Patients who
are randomized to C5 inhibitor therapy in part 1 will discontinue that therapy at the week 24 visit and start BCX9930 for part 2. The primary endpoint of
REDEEM-1 is change from baseline in hemoglobin, as assessed at weeks 12 to 24.

On February 22, 2022, we announced the enrollment of the first patient in the RENEW proof-of-concept basket study with BCX9930 in patients
with C3 glomerulopathy (C3G), IgA nephropathy (IgAN), and primary membranous nephropathy (PMN).  RENEW is an open-label, multicenter, proof-of-
concept study designed to evaluate the safety, tolerability, and therapeutic potential of BCX9930 (twice-daily) administered for 24 weeks in patients with
either C3G, IgAN, or PMN.  All patients will be enrolled into one of three parallel study cohorts, based on confirmation of diagnosis and disease activity in
a recent kidney biopsy, and will receive BCX9930 for the 24-week treatment period.  The primary endpoint of RENEW is percent change from baseline in
24-hour urine protein-to-creatinine ratio (uPCR), as assessed at week 24.

Financing Transactions

Royalty Monetizations. On November 19, 2021, we entered into (i) the 2021 RPI Royalty Purchase Agreement, pursuant to which we sold to RPI the

right to receive certain royalty payments from the Company for a purchase price of $150 million in cash; and (ii) the OMERS Royalty Purchase
Agreement, pursuant to which we sold to OMERS the right to receive certain royalty payments from the Company for a purchase price of an additional
$150 million in cash. Under the Royalty Purchase Agreements, RPI and OMERS are entitled to receive tiered, sales-based royalties on net product sales of
ORLADEYO in the Key Territories and on other Direct Sales. In addition, RPI and OMERS are entitled to receive a tiered revenue share on amounts
generally received by us on account of ORLADEYO sublicense revenue or net sales by licensees outside of the Key Territories. Under the 2021 RPI
Royalty Purchase Agreement, RPI will also be entitled to receive tiered, sales-based royalties on net product sales, if any, of BCX9930 and another earlier
stage Factor D inhibitor, as well as tiered, profit share amounts of up to 3.0% from certain other permitted sales in certain other markets. See “Note 8(cid:0)
Royalty Monetizations(cid:0)ORLADEYO and Factor D Inhibitors” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report for
additional information about our obligations under the Royalty Purchase Agreements.

Sales of Common Stock. On November 19, 2021, concurrent with the 2021 RPI Royalty Purchase Agreement, we entered into a Common Stock

Purchase Agreement (the “Stock Purchase Agreement”) with RPI, pursuant to which we issued to RPI 3,846,154 shares of our common stock for an
aggregate purchase price of approximately $50 million, at a price of $13.00 per share, calculated based on the 20-day volume weighted average price.
These shares were offered and sold without registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance on the exemptions
provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and Rule 506 promulgated under the Securities Act as sales
to an accredited investor.

Amendment to Credit Agreement. On November 19, 2021, we entered into an amendment to our Credit Agreement with Athyrium Opportunities III

Co-Invest 1 LP (“Athyrium” and such agreement, as amended, the “Credit Agreement”), as lender and as administrative agent for the lenders. BioCryst
Ireland Limited and BioCryst US Sales Co., LLC, each of which is a wholly-owned subsidiary of ours, and BioCryst UK Limited, a wholly-owned
subsidiary of BioCryst Ireland Limited, are guarantors to the Credit Agreement. The amendment amended the original Credit Agreement (i) to permit the
Company to enter into the 2021 RPI Royalty Purchase Agreement, the OMERS Royalty Purchase Agreement, and the other definitive documentation
related thereto and to perform its obligations thereunder; (ii) to require the Company to pay to Athyrium, for the account of the lenders, a make-whole
premium plus certain fees set forth in the Credit Agreement in the event that the Company does not draw the Term B Loan or the Term C Loan available
under the Credit Agreement, as applicable, by the end of the applicable period available to draw the Term B Loan or the Term C Loan, subject to certain
exceptions set forth in the Credit Agreement; and (iii) to require the Company to pay to Athyrium, for the account of the lenders, a make-whole premium
plus certain fees set forth in the Credit Agreement in the event that the Company either (x) terminates the commitments in respect of the Term B Loan or
the Term C Loan, as applicable, on or prior to the end of the applicable period available to draw the Term B Loan or the Term C Loan, or (y) prepays or
repays, or is required to prepay or repay, voluntarily or pursuant to a mandatory prepayment obligation under the Credit Agreement (e.g., with the proceeds
of certain asset sales, certain ORLADEYO out-licensing or royalty monetization transactions (excluding the Royalty Sales), extraordinary receipts, debt
issuances, or upon a change of control of the Company and specified other events, subject to certain exceptions), all of the then-outstanding Term Loans
under the Credit Agreement, in each case, subject to certain exceptions set forth in the Credit Agreement. See “Note 9(cid:0)Debt(cid:0)Credit Agreement” in the
Notes to Consolidated Financial Statements in Part II, Item 8 of this report for additional information about our obligations under the Credit Agreement.

Results of Operations

The discussion below presents a summary of our results of operations for fiscal years 2021 and 2020. See Part II, Item 7, “Management’s Discussion

and Analysis of Financial Condition and Results of Operations(cid:0)Results of Operations” of our Annual Report on Form 10-K for the fiscal year ended
December 31, 2020, filed with the Securities and Exchange Commission on March 1, 2021, for a summary of our results of operations for the fiscal year
ended December 31, 2019.

Year Ended December 31, 2021 Compared to 2020

For the year ended December 31, 2021, total revenues were $157.2 million as compared to $17.8 million for the year ended December 31, 2020.

This increase of $139.4 million was primarily due to an increase of $122.5 million of ORLADEYO net revenue following our commercial launch in
December 2020. Additionally, RAPIVAB revenues, primarily from sales to HHS, increased by $6.7 million and peramivir product revenue from inventory
sales to our partners increased by $4.6 million. The Company also recognized a $15.0 million milestone payment related to the NHI approval of
ORLADEYO in Japan. These increases in revenue were partially offset by a reduction in royalty revenue (excluding those associated with ORLADEYO
sales) of $4.2 million, a reduction in contract revenue of $3.3 million and the recognition of $1.9 million of deferred revenue in the prior year period
compared to none in the current year period. The decrease in royalty revenue was due to peramivir product replacement under Green Cross’s supply
agreement with the Korean government.

Cost of product sales for the years ended December 31, 2021 and 2020 was $7.2 million and $1.6 million, respectively, and was primarily associated

with the peramivir product sales to our partners in 2021.

R&D expenses increased to $208.8 million for the year ended December 31, 2021 from $123.0 million for the year ended December 31, 2020,

primarily due to increased investment in the development of our Factor D program, including BCX9930, as well as other research, preclinical and
development costs, which were partially offset by a reduction in spend on the ORLADEYO program following our commercial launch in December 2020.

The following table summarizes our R&D expenses for the periods indicated (amounts are in thousands). Certain prior period amounts have been

reclassified for consistency with the current year presentation. These reclassifications had no effect on the total R&D expenses.

R&D expenses include all direct and indirect expenses and are allocated to specific programs at the point of development of a lead product
candidate. Direct expenses are charged directly to the program to which they relate, and indirect expenses are allocated based upon internal direct labor
hours dedicated to each respective program. Direct expenses consist of compensation for R&D personnel and costs of outside parties to conduct laboratory
studies, develop manufacturing processes, manufacture the product candidates, conduct and manage clinical trials, as well as other costs related to our
clinical and preclinical studies. Indirect R&D expenses consist of lab supplies and services, facility expenses, depreciation of development equipment and
other overhead of our research and development efforts. R&D expenses vary according to the number of programs in clinical development and the stage of
development of our clinical programs. Later stage clinical programs tend to cost more than earlier stage programs due to the longer length of time of the
clinical trials and the higher number of patients enrolled in these clinical trials.

SG&A expenses for the year ended December 31, 2021 were $118.8 million compared to $67.9 million in the year ended December 31, 2020. The

increase was primarily due to increased investment to support the commercial launch of ORLADEYO in the U.S. and elsewhere and our expanded
international operations, particularly in the EU. Additionally, SG&A expenses for 2021 included non-cash stock compensation charges of $8.9 million on
the accelerated vesting of certain outstanding stock options and severance costs of $1.1 million.

Interest expense for the year ended December 31, 2021 was $59.3 million as compared to $14.5 million for the year ended December 31, 2020. The

increase in interest expense was primarily associated with the royalty financing obligations and the $125.0 million Term A Loan under the Credit
Agreement. Interest expense for the year ended December 31, 2021 included $37.7 million of non-cash interest expense due to the amortization of interest
associated with the royalty financing obligations and $15.5 million of interest expense, net of deferred financing amortization, associated with the Term A
Loan under the Credit Agreement. Additionally, we recognized $6.1 million in interest expense on the non-recourse PhaRMA Notes issued in March 2011.
Interest expense for the year ended December 31, 2020 consisted of $6.6 million associated with the non-recourse PhaRMA Notes and $4.9 million
associated with the borrowings under our secured credit facility with MidCap, which terminated in December 2020 when we repaid the outstanding
indebtedness under the facility. Additionally, 2020 interest expense included $2.1 million of non-cash interest expense due to the amortization of interest
associated with the royalty financing obligation and $0.9 million of interest expense, net of deferred financing amortization, associated with the Term A
Loan under the Credit Agreement.

A gain of $55.8 million on extinguishment of debt was recognized for the year ended December 31, 2021 related to the write-off of the non-recourse

PhaRMA Notes and related accrued interest payable. See “Note 8(cid:0)Royalty Monetizations(cid:0)RAPIACTA(cid:0) Non-Recourse Notes Payable – Debt
Extinguishment ” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report for additional information. This gain compares to a loss
on extinguishment of debt of $2.0 million for the year ended December 31, 2020, which is comprised of the write-off of unamortized deferred financing
costs and original issue discount of $1.2 million and a prepayment fee of $0.8 million associated with the repayment of the outstanding indebtedness under
our secured credit facility with MidCap in December 2020.

For the year ended December 31, 2021, other expense of $0.6 million was primarily related to foreign currency losses as compared to other income

of $8.4 million for the year ended December 31, 2020. Other income in 2020 consisted of $8.9 million related to recognition of income from the partial
arbitration award related to our Seqirus arbitration proceedings and $0.5 million of interest income, partially offset by foreign currency losses of $1.0
million.

For the year ended December 31, 2021, we incurred a tax expense of $2.3 million, primarily related to U.S. state taxes. This liability was driven

predominantly by the recognition as upfront taxable income of $300.0 million received from the RPI Royalty Purchase Agreement and the OMERS
Royalty Purchase Agreement, increased sales of ORLADEYO and increased nexus in multiple states where historically we had none.

Liquidity and Capital Resources

Our operations have principally been funded through public offerings and private placements of equity securities; cash from collaborative and other

research and development agreements, including U.S. Government contracts for RAPIVAB and galidesivir; to a lesser extent, the PhaRMA Notes financing
and our credit facilities; and more recently, the Royalty Sales. To date, we have been awarded a BARDA/HHS RAPIVAB development contract totaling
$234.8 million, which expired on June 30, 2014, a NIAID/HHS galidesivir development contract totaling $47.3 million, which is in the process of being
closed out, a second NIAID/HHS galidesivir development contract with a potential value totaling $43.9 million, which is ongoing, and a BARDA/HHS
galidesivir development contract totaling $39.1 million, which is also ongoing. The total amount of funding obligated under awarded options under the
active NIAID/HHS and BARDA/HHS galidesivir contracts is $53.6 million and $20.6 million, respectively. In addition to the above, we have previously
received funding from other sources, including other collaborative and other research and development agreements, government grants, equipment lease
financing, facility leases, research grants, and interest income on our investments.

On November 19, 2021, we entered into the 2021 RPI Royalty Purchase Agreement, the OMERS Royalty Purchase Agreement, and the Stock
Purchase Agreement, pursuant to which we received $350.0 million in new funding for the Company, with all funds immediately available at closing. See
“Note 8(cid:0)Royalty Monetizations(cid:0)ORLADEYO and Factor D Inhibitors” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report
for additional information about these financing transactions.

Our Credit Agreement with Athyrium provides for three term loans. We received the proceeds from the $125.0 million Term A Loan in December

2020. We have committed to draw the two additional term loans available under the Credit Agreement, in the respective principal amounts of $25.0 million
for the Term B Loan and $50.0 million for the Term C Loan. The maturity date of the Credit Agreement is December 7, 2025. See “Note 9(cid:0)Debt(cid:0)Credit
Agreement” in the Notes to Consolidated Financial Statements in Part II, Item 8 of this report for additional information about the Credit Agreement.

As of December 31, 2021, we had net working capital of $462.4 million, an increase of approximately $244.3 million from $218.1 million at

December 31, 2020. The increase in working capital was primarily the result of the $300.0 million of new funding associated with the royalty monetization
transactions and the related $50.0 million from the sale of common stock in the fourth quarter of 2021.  Working capital was also impacted by the write-off
of the non-recourse PhaRMA Notes including associated accrued interest payable, which were previously recorded in current liabilities. Our principal
sources of liquidity at December 31, 2021 were approximately $504.4 million in cash and cash equivalents and approximately $10.0 million in investments
considered available-for-sale.

We intend to contain costs and cash flow requirements by closely managing our third-party costs and headcount, leasing scientific equipment and

facilities, contracting with other parties to conduct certain research and development projects, and using consultants. We expect to incur additional
expenses, potentially resulting in significant losses, as we continue to pursue our research and development activities, commercialize ORLADEYO, and
hire additional personnel. We may incur additional expenses related to the filing, prosecution, maintenance, defense, and enforcement of patent and other
intellectual property claims and additional regulatory costs as our clinical programs advance through later stages of development. The objective of our
investment policy is to ensure the safety and preservation of invested funds, as well as to maintain liquidity sufficient to meet cash flow requirements. We
place our excess cash with high credit quality financial institutions, commercial companies, and government agencies in order to limit the amount of our
credit exposure. We have not realized any significant losses on our investments.

We plan to finance our needs principally from the following:

● lease, royalty, or loan financing and future public or private equity and/or debt financing;
● our existing capital resources and interest earned on that capital;
● revenues from product sales;
● payments under existing, and executing new, contracts with the U.S. Government; and
● payments under current or future collaborative and licensing agreements with corporate partners.

As our commercialization activities and research and development programs continue to advance, our costs will increase. Our current and planned

clinical trials, plus the related development, manufacturing, regulatory approval process requirements, and additional personnel resources and testing
required for the continuing development of our product candidates and the commercialization of our products will consume significant capital resources
and will increase our expenses.

Our expenses, revenues and cash utilization rate could vary significantly depending on many factors, including our ability to raise additional capital,

the development progress of our collaborative agreements for our product candidates, the amount and timing of funding we receive from existing U.S.
Government contracts for galidesivir, the amount of funding or assistance, if any, we receive from new U.S. Government contracts or other new
partnerships with third parties for the development and/or commercialization of our products and product candidates, the progress and results of our current
and proposed clinical trials for our most advanced product candidates, the progress made in the manufacturing of our lead product candidates, the success
of our commercialization efforts for, and market acceptance of, our products, and the overall progression of our other programs. The impact of the ongoing
COVID-19 pandemic on one or more of the foregoing factors could negatively affect our expenses, revenues, and cash utilization rate.

Based on our expectations for revenue, operating expenses and the additional $75 million available to us under the Credit Agreement, we believe our
financial resources will be sufficient to fund our operations for at least the next 12 months. However, we have sustained operating losses for the majority of
our corporate history and expect that our 2022 expenses will exceed our 2022 revenues. We expect to continue to incur operating losses and negative cash
flows until revenues reach a level sufficient to support ongoing operations. Our liquidity needs will be largely determined by the success of operations in
regard to the successful commercialization of our products and the future progression of our product candidates. We regularly evaluate other opportunities
to fund future operations, including: (1) securing or increasing U.S. Government funding of our programs, including obtaining procurement contracts; (2)
out-licensing rights to certain of our products or product candidates, pursuant to which we would receive cash milestone payments; (3) raising additional
capital through equity or debt financings or from other sources, including royalty or other monetization transactions; (4) obtaining additional product
candidate regulatory approvals, which would generate revenue, milestone payments and cash flow; (5) reducing spending on one or more research and
development programs, including by discontinuing development; and/or (6) restructuring operations to change our overhead structure. We may issue
securities, including common stock, preferred stock, depositary shares, purchase contracts, warrants, debt securities, and units, through private placement
transactions or registered public offerings. Our future liquidity needs, and our ability to address those needs, will largely be determined by the success of
our products and product candidates; the timing, scope, and magnitude of our commercial expenses; and key development and regulatory events and our
decisions in the future.

Our long-term capital requirements and the adequacy of our available funds will depend upon many factors, including:

● market acceptance of approved products and successful commercialization of such products by either us or our partners;
● our ability to perform under our government contracts and to receive reimbursement and stockpiling procurement contracts;

49

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● the magnitude of work under our government contracts;
● the progress and magnitude of our research, drug discovery and development programs;
● changes in existing collaborative relationships or government contracts;
● our ability to establish additional collaborative relationships with academic institutions, biotechnology or pharmaceutical companies and

governmental agencies or other third parties;

● the extent to which our partners, including governmental agencies, will share in the costs associated with the development of our programs or

run the development programs themselves;

● our ability to negotiate favorable development and marketing strategic alliances for certain products and product candidates;
● any decision to build or expand internal development and commercial capabilities;
● the scope and results of preclinical studies and clinical trials to identify and develop product candidates;
● our ability to engage sites and enroll subjects in our clinical trials;
● the scope of manufacturing of our products to support our commercial operations and of our product candidates to support our preclinical

research and clinical trials;

● increases in personnel and related costs to support the development and commercialization of our products and product candidates;
● the scope of manufacturing of our drug substance and product candidates required for future NDA filings;
● competitive and technological advances;
● the time and costs involved in obtaining regulatory approvals;
● post-approval commitments for ORLADEYO, RAPIVAB, and other products that receive regulatory approval; and
● the costs involved in all aspects of intellectual property strategy and protection, including the costs involved in preparing, filing, prosecuting,

maintaining, defending, and enforcing patent claims.

We expect that we will be required to raise additional capital to complete the development and commercialization of our current products and
product candidates, and we may seek to raise capital in the future, including to take advantage of favorable opportunities in the capital markets. Additional
funding, whether through additional sales of equity or debt securities, collaborative or other arrangements with corporate partners or from other sources,
including governmental agencies in general and existing government contracts specifically, may not be available when needed or on terms acceptable to us.
The issuance of preferred or common stock or convertible securities, with terms and prices significantly more favorable than those of the currently
outstanding common stock, could have the effect of diluting or adversely affecting the holdings or rights of our existing stockholders. In addition,
collaborative arrangements may require us to transfer certain material rights to such corporate partners. Insufficient funds may require us to delay, scale
back or eliminate certain of our research and development programs. Our future working capital requirements, including the need for additional working
capital, will be largely determined by the advancement of our portfolio of product candidates and the commercialization of ORLADEYO, as well as the
rate of reimbursement by U.S. Government agencies of our galidesivir expenses and any future decisions regarding the future of the RAPIVAB and
galidesivir programs, including those relating to stockpiling procurement. More specifically, our working capital requirements will be dependent on the
number, magnitude, scope and timing of our development programs; regulatory approval of our product candidates; obtaining funding from collaborative
partners; the cost, timing and outcome of regulatory reviews, regulatory investigations, and changes in regulatory requirements; the costs of obtaining
patent protection for our product candidates; the timing and terms of business development activities; the rate of technological advances relevant to our
operations; the efficiency of manufacturing processes developed on our behalf by third parties; the timing, scope and magnitude of commercial spending,
and the level of required administrative support for our daily operations.

The restrictive covenants contained in our Credit Agreement could cause us to be unable to pursue business opportunities that we or our stockholders
may consider beneficial without the lender’s permission or without repaying all obligations outstanding under the Credit Agreement. These covenants limit
our ability to, among other things, grant certain types of liens on our assets; make certain investments; incur or assume certain debt, including accessing
additional tranches of debt under the Credit Agreement; engage in certain mergers, acquisitions, and similar transactions; dispose of assets; license certain
property; distribute dividends; make certain restricted payments; change the nature of our business; engage in transactions with affiliates and insiders;
prepay other indebtedness; or engage in sale and leaseback transactions. A breach of any of these covenants could result in an event of default under the
Credit Agreement. As of December 31, 2021, we were in compliance with the covenants under the Credit Agreement.

Financial Outlook for 2022

Based on the strength of the ORLADEYO launch, and continued growth from new patient demand anticipated throughout the year, we expect full

year 2022 net ORLADEYO revenue to be no less than $250 million. We expect operating expenses for full year 2022, not including non-cash stock
compensation, to be in the range of $440 million to $480 million, with the year-over-year increase predominantly driven by additional investment in
advancing our Factor D program across multiple indications.  Based on our expectations for revenue, operating expenses, and the additional $75 million
available under our existing credit facility, we believe our current cash funds our planned operations for at least the next 12 months.

Critical Accounting Policies

We have established various accounting policies that govern the application of U.S. GAAP, which were utilized in the preparation of our

consolidated financial statements. Certain accounting policies involve significant judgments and assumptions by management that have a material impact
on the carrying value of certain assets and liabilities. Management considers such accounting policies to be critical accounting policies. The judgments and
assumptions used by management are based on historical experience and other factors, which are believed to be reasonable under the circumstances.
Because of the nature of the judgments and assumptions made by management, actual results could differ from these judgments and estimates, which could
have a material impact on the carrying values of assets and liabilities and the results of operations.

While our significant accounting policies are more fully described in “Note 1−Significant Accounting Policies and Concentrations of Risk” to the

Consolidated Financial Statements in Part I, Item 1 of this report, we believe that the following accounting policies are the most critical to aid you in fully
understanding and evaluating our reported financial results and affect the more significant judgments and estimates that we use in the preparation of our
financial statements.

Revenue Recognition

Pursuant to Accounting Standards Codification (“ASC”) Topic 606, we recognize revenue to depict the transfer of promised goods or services to
customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this
core principle, Topic 606 includes provisions within a five step model that includes (i) identifying the contract with a customer, (ii) identifying the
performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the performance obligations, and (v)
recognizing revenue when, or as, an entity satisfies a performance obligation.

At contract inception, we identify the goods or services promised within each contract, assess whether each promised good or service is distinct, and

determine those that are performance obligations. We recognize as revenue the amount of the transaction price that is allocated to the respective
performance obligation when the performance obligation is satisfied.

Product Sales, Net

Our principal sources of product sales are sales of ORLADEYO, which we began shipping to patients in December 2020, sales of peramivir to our
licensing partners and sales of RAPIVAB to the U.S. Department of Health and Human Services under our procurement contract. In the United States, we
ship ORLADEYO directly to patients through a single specialty pharmacy, which is considered our customer. In the European Union, United Kingdom and
elsewhere, we sell ORLADEYO to specialty distributors as well as hospitals and pharmacies, which collectively are considered our customers.

We recognize revenue for sales when our customers obtain control of the product, which generally occurs upon delivery. For ORLADEYO, we

classify payments to our specialty pharmacy customer for certain services provided by our customer as selling, general and administrative expenses to the
extent such services provided are determined to be distinct from the sale of our product.

Net revenue from sales of ORLADEYO is recorded at net selling price (transaction price), which includes estimates of variable consideration for

which reserves are established for (i) estimated government rebates, such as Medicaid and Medicare Part D reimbursements, and estimated managed care
rebates, (ii) estimated chargebacks, (iii) estimated costs of co-payment assistance programs and (iv) product returns. These reserves are based on the
amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable or as a current liability. Overall, these reserves
reflect our best estimates of the amount of consideration to which it is entitled based on the terms of the applicable contract. The amount of variable
consideration included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a
significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately
received may differ from our estimates. If actual results in the future vary from estimates, we adjust these estimates, which would affect net product
revenue and earnings in the period such variances become known.

Government and Managed Care Rebates. We contract with government agencies and managed care organizations or, collectively, third-party payors,

so that ORLADEYO will be eligible for purchase by, or partial or full reimbursement from, such third-party payors. We estimate the rebates we will
provide to third-party payors and deduct these estimated amounts from total gross product revenues at the time the revenues are recognized. We estimate
the rebates that we will provide to third-party payors based upon (i) our contracts with these third-party payors, (ii) the government mandated discounts
applicable to government-funded programs, (iii) a range of possible outcomes that are probability-weighted for the estimated payor mix, and (iv) product
distribution information obtained from our specialty pharmacy.

Chargebacks. Chargebacks are discounts that occur when certain contracted customers, pharmacy benefit managers, insurance companies and
government programs purchase directly from our specialty pharmacy. These customers purchase our products under contracts negotiated between them and
our specialty pharmacy. The specialty pharmacy, in turn, charges back to us the difference between the price the specialty pharmacy paid and the negotiated
price paid by the contracted customers, which may be higher or lower than the specialty pharmacy purchase price with us. We estimate chargebacks and
adjust gross product revenues and accounts receivable based on the estimates at the time revenues are recognized.

51

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Co-payment assistance and patient assistance programs. Patients who have commercial insurance and meet certain eligibility requirements may

receive co-payment assistance. Based upon the terms of the program and co-payment assistance utilization reports received from the specialty pharmacy,
we are able to estimate the co-payment assistance amounts, which are recorded in the same period in which the related revenue is recognized, resulting in a
reduction of product revenue. We also offer a patient assistance program that provides free drug product, for a limited period of time, to allow a patient’s
insurance coverage to be established. Based on patient assistance program utilization reports provided by the specialty pharmacy, we record gross revenue
of the product provided and a full reduction of the revenue amount for the free drug discount.

Product returns. We do not provide contractual return rights to our customer, except in instances where the product is damaged or defective. Non-

acceptance by the patient of shipped drug product by the specialty pharmacy is reflected as a reversal of sales in the period in which the sales were
originally recorded. Reserves for estimated non-acceptances by patients are recorded as a reduction of revenue in the period that the related revenue is
recognized, as well as a reduction to accounts receivable. Estimates of non-acceptance are based on quantitative information provided by the specialty
pharmacy.

Collaborative and Other Research and Development Arrangements and Royalties

We recognize revenue when we satisfy a performance obligation by transferring promised goods or services to a customer. Revenue is measured at
the transaction price that is based on the amount of consideration that we expect to receive in exchange for transferring the promised goods or services to
the customer. The transaction price includes estimates of variable consideration to the extent it is probable that a significant reversal of revenue recognized
will not occur.

We have collaboration and license agreements with a number of third parties as well as research and development agreements with certain

government entities.

Our primary sources of revenue from these collaborative and other research and development arrangements are license, service and royalty revenues.

Revenue from license fees, royalty payments, milestone payments, and research and development fees are recognized as revenue when the earnings
process is complete and we have no further continuing performance obligations or we have completed the performance obligations under the terms of the
agreement.

Arrangements that involve the delivery of more than one performance obligation are initially evaluated as to whether the intellectual property
licenses granted by us represent distinct performance obligations. If they are determined to be distinct, the value of the intellectual property licenses would
be recognized up-front while the research and development service fees would be recognized as the performance obligations are satisfied. For performance
obligations based on services performed, we measure progress using an input method based on the effort we expend or costs we incur toward the
satisfaction of the performance obligation in relation to the total estimated effort or costs. Variable consideration is assessed at each reporting period as to
whether it is not subject to significant future reversal and, therefore, should be included in the transaction price at the inception of the contract. If a contract
includes a fixed or minimum amount of research and development support, this also would be included in the transaction price. Changes to collaborations,
such as the extensions of the research term or increasing the number of targets or technology covered under an existing agreement, are assessed for whether
they represent a modification or should be accounted for as a new contract. For contracts with multiple performance obligations, revenue is allocated to
each performance obligation based on its relative standalone selling price. Standalone selling prices are based on observable prices at which we separately
sell the products or services. If a standalone selling price is not directly observable, then we estimate the standalone selling price using either an adjusted
market assessment approach or an expected cost plus margin approach, representing the amount that we believe the market is willing to pay for the product
or service. Analyzing the arrangement to identify performance obligations requires the use of judgment, and each may be an obligation to deliver services,
a right or license to use an asset, or another performance obligation.

Milestone payments are recognized as licensing revenue upon the achievement of specified milestones if (i) the milestone is substantive in nature
and the achievement of the milestone was not probable at the inception of the agreement; and (ii) we have a right to payment. Any milestone payments
received prior to satisfying these revenue recognition criteria are recorded as deferred revenue.

Reimbursements received for direct out-of-pocket expenses related to research and development costs are recorded as revenue in the Consolidated

Statements of Comprehensive Loss rather than as a reduction in expenses. Under our contracts with BARDA/HHS and NIAID/HHS, revenue is recognized
as reimbursable direct and indirect costs are incurred.

Under certain of our license agreements, we receive royalty payments based upon our licensees’ net sales of covered products. Royalties are
recognized at the later of when (i) the subsequent sale or usage occurs; or (ii) the performance obligation to which some or all of the sales-based or usage-
based royalty has been satisfied.

Inventory

Our inventories primarily relate to ORLADEYO. Additionally, our inventory includes RAPIVAB and peramivir, which are manufactured for the

Company’s partners.

52

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We value our inventories at the lower of cost or estimated net realizable value. We determine the cost of our inventories, which includes amounts

related to materials, labor, manufacturing overhead and shipping and handling costs on a first-in, first-out (FIFO) basis. Raw materials and work-in-process
includes all inventory costs prior to packaging and labeling, including raw material, active product ingredient, and drug product. Finished goods include
packaged and labeled products.

Our inventories are subject to expiration dating. We regularly evaluate the carrying value of our inventories and provide valuation reserves for any

estimated obsolete, short-dated or unmarketable inventories. In addition, we may experience spoilage of our raw materials and supplies. Our determination
that a valuation reserve might be required, in addition to the quantification of such reserve, requires us to utilize significant judgment.

We expense costs related to the production of inventories as research and development expenses in the period incurred until such time it is believed
that future economic benefit is expected to be recognized, which generally is upon receipt of regulatory approval. Upon regulatory approval, we capitalize
subsequent costs related to the production of inventories.

Accrued Expenses

We enter into contractual agreements with third-party vendors who provide research and development, manufacturing, distribution, and other
services in the ordinary course of business. Some of these contracts are subject to milestone-based invoicing, and services are completed over an extended
period of time. We record liabilities under these contractual commitments when we determine an obligation has been incurred. This accrual process
involves reviewing open contracts and purchase orders, communicating with our applicable personnel to identify services that have been performed and
estimating the level of service performed and the associated cost when we have not yet been invoiced or otherwise notified of actual cost. The majority of
our service providers invoice us monthly in arrears for services performed. We make estimates of our accrued expenses as of each balance sheet date based
on the facts and circumstances known to us. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if
necessary. Examples of estimated accrued expenses include (i) fees paid to clinical research organizations (“CROs”) in connection with preclinical and
toxicology studies and clinical trials; (ii) fees paid to investigative sites in connection with clinical trials; (iii) fees paid to contract manufacturers in
connection with the production of our raw materials, drug substance, drug products, and product candidates; and (iv) professional fees.

We base our expenses related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts with multiple

research institutions and CROs that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation,
vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful
enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be
performed and the level of effort expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate,
we will adjust the accrual accordingly. If we do not identify costs that we have begun to incur or if we underestimate or overestimate the level of these
costs, our actual expenses could differ from our estimates.

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets) and

deferred revenue and billings in excess of revenue recognized (contract liabilities) on the Consolidated Balance Sheets.

Contract assets. Our long-term contracts are billed as work progresses in accordance with the contract terms and conditions, either at periodic
intervals or upon achievement of certain milestones. Often this results in billing occurring subsequent to revenue recognition, resulting in contract assets.
Contract assets are generally classified as current assets in the Consolidated Balance Sheets.

Contract liabilities. We often receive cash payments from customers in advance of our performance, resulting in contract liabilities. These contract
liabilities are classified as either current or long-term in the Consolidated Balance Sheets based on the timing of when we expect to recognize the revenue.

Contract Costs

We may incur direct and indirect costs associated with obtaining a contract. Incremental contract costs that we expect to recover are capitalized and

amortized over the expected term of the contract. Non-incremental contract costs and costs that we expect to recover are expensed as incurred.

Research and Development Expenses

Our research and development costs are charged to expense when incurred. Advance payments for goods or services that will be used or rendered for

future research and development activities are deferred and capitalized. Such amounts are recognized as expense when the related goods are delivered or
the related services are performed. Research and development expenses include, among other items, personnel costs, including salaries and benefits,
manufacturing costs, clinical, regulatory, and toxicology services performed by CROs, materials and supplies, and overhead allocations consisting of
various administrative and facilities related costs. Most of our manufacturing and clinical and preclinical studies are performed by third-party CROs. Costs
for studies performed by CROs are accrued by us over the service periods specified in the contracts and estimates are adjusted, if required, based upon our
ongoing review of the level of services actually performed.

53

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Additionally, we have license agreements with third parties, such as Albert Einstein College of Medicine of Yeshiva University (“AECOM”),
Industrial Research, Ltd. (“IRL”), and the University of Alabama (“UAB”), which require fees related to sublicense agreements or maintenance fees. We
expense sublicense payments as incurred unless they are related to revenues that have been deferred, in which case the expenses are deferred and
recognized over the related revenue recognition period. We expense maintenance payments as incurred.

Deferred collaboration expenses represent sub-license payments paid to our academic partners upon receipt of consideration from various

commercial partners, and other consideration to our academic partners for modification to existing license agreements. These deferred expenses would not
have been incurred without receipt of such payments or modifications from our commercial partners and are being expensed in proportion to the related
revenue being recognized. We believe that this accounting treatment appropriately matches expenses with the associated revenue.

We group our R&D expenses into two major categories: direct external expenses and indirect expenses. Direct expenses consist of compensation for

R&D personnel and costs of outside parties to conduct laboratory studies, develop manufacturing processes and manufacture the product candidate,
conduct and manage clinical trials, as well as other costs related to our clinical and preclinical studies. These costs are accumulated and tracked by active
program. Indirect expenses consist of lab supplies and services, facility expenses, depreciation of development equipment and other overhead of our
research and development efforts. These costs apply to work on non-active product candidates and our discovery research efforts.

Stock-Based Compensation

All share-based payments, including grants of stock option awards and restricted stock unit awards, are recognized in our Consolidated Statements
of Comprehensive Loss based on their fair values. Stock-based compensation cost is estimated at the grant date based on the fair value of the award and is
recognized as expense on a straight-line basis over the requisite service period of the award. Determining the appropriate fair value model and the related
assumptions for the model requires judgment, including estimating the life of an award, the stock price volatility, and the expected term. We utilize the
Black-Scholes option-pricing model to value our awards and recognize compensation expense on a straight-line basis over the vesting periods. The
estimation of share-based payment awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from our
current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised. In addition, we have outstanding
performance-based stock options for which no compensation expense is recognized until “performance” has occurred. Significant management judgment is
also required in determining estimates of future stock price volatility and forfeitures to be used in the valuation of the options. Actual results, and future
changes in estimates, may differ substantially from our current estimates.

Interest Expense and Royalty Financing Obligations

The royalty financing obligations are eligible to be repaid based on royalties from net sales of ORLADEYO, BCX9930, and another earlier stage

Factor D inhibitor. Interest expense is accrued using the effective interest rate method over the estimated period each of the related liabilities will be paid.
This requires us to estimate the total amount of future royalty payments to be generated from product sales over the life of the agreement. We impute
interest on the carrying value of each of the royalty financing obligations and record interest expense using an imputed effective interest rate. We reassess
the expected royalty payments each reporting period and account for any changes through an adjustment to the effective interest rate on a prospective basis.
The assumptions used in determining the expected repayment term of the debt and amortization period of the issuance costs requires that we make
estimates that could impact the carrying value of each of the liabilities, as well as the periods over which associated issuance costs will be amortized. A
significant increase or decrease in forecasted net sales could materially impact each of the liability balances, interest expense and the time periods for
repayment.

Foreign Currency Hedge

In connection with our issuance of the PhaRMA Notes, we entered into a foreign Currency Hedge Agreement to hedge certain risks associated with

changes in the value of the Japanese yen relative to the U.S. dollar. The final tranche of the options under the Currency Hedge Agreement expired in
November 2020. The Currency Hedge Agreement did not qualify for hedge accounting treatment and therefore mark-to-market adjustments were
recognized in our Consolidated Statements of Comprehensive Loss.

Tax

We account for uncertain tax positions in accordance with U.S. GAAP. Significant management judgment is required in determining our provision

for income taxes, deferred tax assets and liabilities and any valuation allowance recorded against net deferred tax assets. We have recorded a valuation
allowance against substantially all potential tax assets, due to uncertainties in our ability to utilize deferred tax assets, primarily consisting of certain net
operating losses carried forward, before they expire. The valuation allowance is based on estimates of taxable income in each of the jurisdictions in which
we operate and the period over which our deferred tax assets will be recoverable.

Recent Accounting Pronouncements

“Note 1(cid:0)Significant Accounting Policies and Concentrations of Risk” to the Consolidated Financial Statements included in Part II, Item 8 of this

report discusses accounting pronouncements recently issued or proposed but not yet required to be adopted.

ITEM 7A.         QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Interest Rate Risk

We are subject to interest rate risk on our investment portfolio and borrowings under our Credit Agreement. The Term A Loan under the Credit

Agreement bears interest each quarter at a rate equal to the three-month LIBOR rate, which is capped to be no less than 1.75% and no more than 3.50%
(“LIBOR”), plus 8.25% or, for each quarterly interest period in which a PIK Interest Payment is made, the LIBOR plus 10.25%. Accordingly, increases in
interest rates could increase the associated interest payments that we are required to make on the term loans. As of December 31, 2021, interest was accrued
at 12.2% on the $125.0 million Term A Loan under the Credit Agreement.

We invest in marketable securities in accordance with our investment policy. The primary objectives of our investment policy are to preserve capital,

maintain proper liquidity to meet operating needs and maximize yields. Our investment policy specifies credit quality standards for our investments and
limits the amount of credit exposure to any single issue, issuer or type of investment. We place our excess cash with high credit quality financial
institutions, commercial companies, and government agencies in order to limit the amount of credit exposure. Some of the securities we invest in may have
market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate.

Our investment exposure to market risk for changes in interest rates relates to the increase or decrease in the amount of interest income we can earn

on our portfolio, changes in the market value due to changes in interest rates and other market factors as well as the increase or decrease in any realized
gains and losses. Our investment portfolio includes only marketable securities and instruments with active secondary or resale markets to help ensure
portfolio liquidity. A hypothetical 100 basis point increase or decrease in interest rates along the entire interest rate yield curve would not significantly
affect the fair value of our interest sensitive financial instruments, including our borrowings, but may affect our future earnings and cash flows. We
generally have the ability to hold our fixed-income investments to maturity and therefore do not expect that our operating results, financial position or cash
flows will be materially impacted due to a sudden change in interest rates. However, our future investment income may fall short of expectations due to
changes in interest rates, or we may suffer losses in principal if forced to sell securities which have declined in market value due to changes in interest rates
or other factors, such as changes in credit risk related to the securities’ issuers. To minimize this risk, we schedule our investments to have maturities that
coincide with our expected cash flow needs, thus avoiding the need to redeem an investment prior to its maturity date. Accordingly, we do not believe that
we have material exposure to interest rate risk arising from our investments. Generally, our investments are not collateralized. We have not realized any
significant losses from our investments.

We do not use interest rate derivative instruments to manage exposure to interest rate changes. We ensure the safety and preservation of invested

principal funds by limiting default risk, market risk and reinvestment risk. We reduce default risk by investing in investment grade securities.

Foreign Currency Risk

Most of our revenues and expenses are denominated in U.S. dollars, and as a result, we have not experienced significant foreign currency transaction

gains and losses to date. Our commercial sales in Europe are primarily denominated in Euros and the British Pound. We also had other transactions
denominated in foreign currencies during the year ended December 31, 2021, primarily related to operations in Europe, contract manufacturing and ex-U.S.
clinical trial activities, and we expect to continue to do so. Our royalties from Torii are derived from Torii’s sales of ORLADEYO in Japan. Those sales are
denominated in Japanese yen and converted into U.S. dollars for purposes of determining the royalty owed to us. Our limited foreign currency exposure
relative to our European operations is to fluctuations in the Euro, British Pound, Swiss Franc, Danish Krone, and Swedish Krona. We do not anticipate that
foreign currency transaction gains or losses will be significant at our current level of operations. However, transaction gains or losses may become
significant in the future as we continue to expand our operations internationally. We have not engaged in foreign currency hedging during 2021; however,
we may do so in the future.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(In thousands, except per share amounts)

Note 1 — Significant Accounting Policies and Concentrations of Risk

The Company

BioCryst Pharmaceuticals, Inc. (the “Company”) is a commercial-stage biotechnology company that discovers novel, oral, small-molecule
medicines. The Company focuses on the treatment of rare diseases in which significant unmet medical needs exist and an enzyme plays the key role in the
biological pathway of the disease. The Company was founded in 1986 and incorporated in Delaware in 1991, and its headquarters is located in Durham,
North Carolina. The Company integrates the disciplines of biology, crystallography, medicinal chemistry and computer modeling to discover and develop
small molecule pharmaceuticals through the process known as structure-guided drug design.

The Company’s marketed products include oral, once-daily ORLADEYO® for the prevention of hereditary angioedema (“HAE”) attacks and
RAPIVAB® (peramivir injection) for the treatment of acute uncomplicated influenza in the United States.  ORLADEYO received regulatory approval in
the United States in December 2020.  During 2021, ORLADEYO received regulatory approvals in the European Union, Japan, the United Arab Emirates
and the United Kingdom.  The Company is commercializing ORLADEYO in each of these territories directly or through distributors, except in Japan
where Torii Pharmaceuticals Co., Ltd. (“Torii”), the Company’s collaborative partner, has the exclusive right to commercialize ORLADEYO for the
prevention of HAE attacks in exchange for certain milestone and royalty payments to us.  In addition to its approval in the United States, peramivir
injection has received regulatory approvals in Canada, Australia, Japan, Taiwan and Korea. 

Based on the Company’s expectations for revenue, operating expenses, and the additional $75 million available to the Company under its existing
credit facility, the Company believes its financial resources available at December 31, 2021 will be sufficient to fund its operations for at least the next 12
months. The Company has sustained operating losses for the majority of its corporate history and expects that its 2022 expenses will exceed its 2022
revenues. The Company expects to continue to incur operating losses and negative cash flows until revenues reach a level sufficient to support ongoing
operations. The Company’s liquidity needs will be largely determined by the success of operations in regard to the successful commercialization of its
products and the progression of its product candidates in the future. The Company regularly evaluates other opportunities to fund future operations,
including: (1) securing or increasing U.S. Government funding of its programs, including obtaining procurement contracts; (2) out-licensing rights to
certain of its products or product candidates, pursuant to which the Company would receive cash milestone payments; (3) raising additional capital through
equity or debt financings or from other sources, including royalty or other monetization transactions; (4) obtaining additional product candidate regulatory
approvals, which would generate revenue, milestone payments and cash flow; (5) reducing spending on one or more research and development programs,
including by discontinuing development; and/or (6) restructuring operations to change its overhead structure. The Company may issue securities, including
common stock, preferred stock, depositary shares, purchase contracts, warrants, debt securities and units, through private placement transactions or
registered public offerings in the future. The Company’s future liquidity needs, and ability to address those needs, will largely be determined by the success
of its products and product candidates, timing, scope and magnitude of its commercial expenses and key development and regulatory events and its
decisions in the future.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances among

the consolidated entities have been eliminated from the consolidated financial statements.

The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United

States (“U.S. GAAP”). Such consolidated financial statements reflect all adjustments that are, in management’s opinion, necessary to present fairly, in all
material respects, the Company’s consolidated financial position, results of operations, and cash flows. There were no adjustments other than normal
recurring adjustments.

Reclassifications/Revisions

The Company has reclassified certain non-cash expense amounts on the Consolidated Statement of Cash Flows for the year ended December 31,

2020, to conform with the current year presentation.  Additionally, the Company revised its Consolidated Statement of Cash Flows for the year ended
December 31, 2020 to reflect an immaterial correction whereby net cash used in operating activities was revised from $(137,216) to $(135,108) and net
cash provided by financing activities was revised from $302,697 to $300,589.  The reclassifications and correction had no effect on net cash flows and no
impact on the Consolidated Balance Sheet, Consolidated Statement of Comprehensive Loss, Consolidated Statement of Stockholders’ Equity (Deficit), or
the net loss or loss per share for the year ended December 31, 2020.

60

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the

reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. The most significant estimates in
the Company’s consolidated financial statements relate to the valuation of stock options, the ORLADEYO royalty financing obligations and the valuation
allowance for deferred tax assets resulting from net operating losses. These estimates are based on historical experience and on various other assumptions
that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and
liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.

Revenue Recognition

Pursuant to Accounting Standards Codification (“ASC”) Topic 606, the Company recognizes revenue to depict the transfer of promised goods or

services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To
achieve this core principle, Topic 606 includes provisions within a five step model that includes i) identifying the contract with a customer, ii) identifying
the performance obligations in the contract, iii) determining the transaction price, iv) allocating the transaction price to the performance obligations, and v)
recognizing revenue when, or as, an entity satisfies a performance obligation.

At contract inception, the Company identifies the goods or services promised within each contract, assesses whether each promised good or service
is distinct and determines those that are performance obligations. The Company recognizes as revenue the amount of the transaction price that is allocated
to the respective performance obligation when the performance obligation is satisfied.

Product Sales, Net

The Company’s principal sources of product sales are sales of ORLADEYO, which the Company began shipping to patients in December 2020,

sales of peramivir to the Company’s licensing partners and sales of RAPIVAB to the U.S. Department of Health and Human Services under the Company’s
procurement contract. In the United States, the Company ships ORLADEYO directly to patients through a single specialty pharmacy, which is considered
its customer. In the European Union, United Kingdom and elsewhere, the Company sells ORLADEYO to specialty distributors as well as hospitals and
pharmacies, which collectively are considered its customers.

The Company recognizes revenue for sales when its customers obtain control of the product, which generally occurs upon delivery. For
ORLADEYO, the Company classifies payments to its specialty pharmacy customer for certain services provided by its customer as selling, general and
administrative expenses to the extent such services provided are determined to be distinct from the sale of its product.

Net revenue from sales of ORLADEYO is recorded at net selling price (transaction price), which includes estimates of variable consideration for
which reserves are established for (i) estimated government rebates, such as Medicaid and Medicare Part D reimbursements, and estimated managed care
rebates, (ii) estimated chargebacks, (iii) estimated costs of co-payment assistance programs and (iv) product returns. These reserves are based on the
amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable or as a current liability. Overall, these reserves
reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the applicable contract. The amount of
variable consideration included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a
significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately
received may differ from the Company's estimates. If actual results in the future vary from estimates, the Company adjusts these estimates, which would
affect net product revenue and earnings in the period such variances become known.

Government and Managed Care Rebates. The Company contracts with government agencies and managed care organizations or, collectively,
third-party payors, so that ORLADEYO will be eligible for purchase by, or partial or full reimbursement from, such third-party payors. The Company
estimates the rebates it will provide to third-party payors and deducts these estimated amounts from total gross product revenues at the time the revenues
are recognized. These reserves are recorded in the same period in which the revenue is recognized, resulting in a reduction of product revenue and the
establishment of a current liability. The Company estimates the rebates that it will provide to third-party payors based upon (i) the Company's contracts
with these third-party payors, (ii) the government mandated discounts applicable to government-funded programs, (iii) a range of possible outcomes that
are probability-weighted for the estimated payor mix, and (iv) product distribution information obtained from the Company's specialty pharmacy.

Chargebacks. Chargebacks are discounts that occur when certain contracted customers, pharmacy benefit managers, insurance companies and

government programs purchase directly from the Company’s specialty pharmacy. These customers purchase the Company’s product under contracts
negotiated between them and the Company’s specialty pharmacy. The specialty pharmacy, in turn, charges back to the Company the difference between the
price the specialty pharmacy paid and the negotiated price paid by the contracted customers, which may be higher or lower than the specialty pharmacy’s
purchase price from the Company. The Company estimates chargebacks and adjusts gross product revenues and accounts receivable based on the estimates
at the time revenues are recognized.

61

 
 
 
 
 
 
 
 
 
 
 
 
 
Co-payment assistance and patient assistance programs. Patients who have commercial insurance and meet certain eligibility requirements may
receive co-payment assistance. Based upon the terms of the program and co-payment assistance utilization reports received from the specialty pharmacy,
the Company is able to estimate the co-payment assistance amounts, which are recorded in the same period in which the related revenue is recognized,
resulting in a reduction of product revenue. The Company also offers a patient assistance program that provides free drug product, for a limited period of
time, to allow a patient’s insurance coverage to be established. Based on patient assistance program utilization reports provided by the specialty pharmacy,
the Company records gross revenue of the product provided and a full reduction of the revenue amount for the free drug discount.

Product returns. The Company does not provide contractual return rights to its customer, except in instances where the product is damaged or
defective. Non-acceptance by the patient of shipped drug product by the specialty pharmacy is reflected as a reversal of sales in the period in which the
sales were originally recorded. Reserves for estimated non-acceptances by patients are recorded as a reduction of revenue in the period that the related
revenue is recognized, as well as a reduction to accounts receivable. Estimates of non-acceptance are based on quantitative information provided by the
specialty pharmacy.

Collaborative and Other Research and Development Arrangements and Royalties

The Company has collaboration and license agreements with a number of third parties, as well as research and development agreements with certain

government entities. The Company’s primary sources of revenue from these collaborative and other research and development arrangements are license,
service and royalty revenues.

Revenue from license fees, royalty payments, milestone payments, and research and development fees are recognized as revenue when the earnings

process is complete and the Company has no further continuing performance obligations or the Company has completed the performance obligations under
the terms of the agreement.

Arrangements that involve the delivery of more than one performance obligation are initially evaluated as to whether the intellectual property licenses

granted by the Company represent distinct performance obligations. If they are determined to be distinct, the value of the intellectual property licenses
would be recognized up front while the research and development service fees would be recognized as the performance obligations are satisfied. For
performance obligations based on services performed, the Company measures progress using an input method based on the effort it expends or costs it
incurs toward the satisfaction of the performance obligation in relation to the total estimated effort or costs. Variable consideration is assessed at each
reporting period as to whether it is not subject to significant future reversal and, therefore, should be included in the transaction price at the inception of the
contract. If a contract includes a fixed or minimum amount of research and development support, this also would be included in the transaction price.
Changes to collaborations, such as the extensions of the research term or increasing the number of targets or technology covered under an existing
agreement, are assessed for whether they represent a modification or should be accounted for as a new contract. For contracts with multiple performance
obligations, revenue is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are based on
observable prices at which the Company separately sells the products or services. If a standalone selling price is not directly observable, then the Company
estimates the standalone selling price using either an adjusted market assessment approach or an expected cost plus margin approach, representing the
amount that the Company believes the market is willing to pay for the product or service. Analyzing the arrangement to identify performance obligations
requires the use of judgment, and each may be an obligation to deliver services, a right or license to use an asset, or another performance obligation.

Milestone payments are recognized as licensing revenue upon the achievement of specified milestones if (i) the milestone is substantive in nature and
the achievement of the milestone was not probable at the inception of the agreement; and (ii) the Company has a right to payment. Any milestone payments
received prior to satisfying these revenue recognition criteria are recorded as deferred revenue.

Reimbursements received for direct out-of-pocket expenses related to research and development costs are recorded as revenue in the Consolidated
Statements of Comprehensive Loss rather than as a reduction in expenses. Under the Company’s contracts with the Biomedical Advanced Research and
Development Authority within the United States Department of Health and Human Services (”BARDA/HHS”) and the National Institute of Allergy and
Infectious Diseases (“NIAID/HHS”), revenue is recognized as reimbursable direct and indirect costs are incurred.

Under certain of the Company’s license agreements, the Company receives royalty payments based upon its licensees’ net sales of covered products.

Royalties are recognized at the later of when (i) the subsequent sale or usage occurs, or (ii) the performance obligation to which some or all of the sales-
based or usage-based royalty has been satisfied.

62

 
 
 
 
 
 
 
 
 
 
 
Cash and Cash Equivalents

The Company generally considers cash equivalents to be all cash held in commercial checking accounts, certificates of deposit, money market
accounts or investments in debt instruments with maturities of three months or less at the time of purchase. The carrying value of cash and cash equivalents
approximates fair value due to the short-term nature of these items.

Restricted Cash

Restricted cash as of December 31, 2021 and 2020 reflects $1,924 and $796, respectively, in royalty revenue paid by Shionogi & Co., Ltd.

(“Shionogi”) designated for interest on the PhaRMA Notes (defined in Note 8) and $1,421 and $1,425, respectively, the Company is required to maintain as
collateral for a letter of credit associated with the lease execution and build-out of its new Birmingham research facilities.

Investments

The Company invests in high credit quality investments in accordance with its investment policy, which is designed to minimize the possibility of

loss. The objective of the Company’s investment policy is to ensure the safety and preservation of invested funds, as well as maintaining liquidity sufficient
to meet cash flow requirements. The Company places its excess cash with high credit quality financial institutions, commercial companies, and government
agencies in order to limit the amount of its credit exposure. In accordance with its policy, the Company is able to invest in marketable debt securities that
may consist of U.S. Government and government agency securities, money market and mutual fund investments, certificates of deposits, municipal and
corporate notes and bonds, and commercial paper, among others. The Company’s investment policy requires it to purchase high-quality marketable
securities with a maximum individual maturity of three years and requires an average portfolio maturity of no more than 12 months. Some of the securities
the Company invests in may have market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to
fluctuate. To minimize this risk, the Company schedules its investments with maturities that coincide with expected cash flow needs, thus avoiding the need
to redeem an investment prior to its maturity date. Accordingly, the Company does not believe it has a material exposure to interest rate risk arising from its
investments. Generally, the Company’s investments are not collateralized. The Company has not realized any significant losses from its investments.

The Company classifies all of its investments as available-for-sale. Unrealized gains and losses on investments are recognized in comprehensive

loss, unless an unrealized loss is considered to be other than temporary, in which case the unrealized loss is charged to operations. The Company
periodically reviews its investments for other than temporary declines in fair value below cost basis and whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. The Company believes the individual unrealized losses represent temporary declines
primarily resulting from interest rate changes. Realized gains and losses are reflected in interest and other income in the Consolidated Statements of
Comprehensive Loss and are determined using the specific identification method with transactions recorded on a settlement date basis. Investments with
original maturities at date of purchase beyond three months and which mature at or less than 12 months from the balance sheet date are classified as
current. Investments with a maturity beyond 12 months from the balance sheet date are classified as long-term. At December 31, 2021, the Company
believes that the cost of its investments is recoverable in all material respects.

Trade Receivables

The majority of the Company’s trade receivables arise from product sales and primarily represent amounts due from our specialty pharmacy
customer in the U.S. and other third-party distributors, hospitals and pharmacies in the European Union, United Kingdom and elsewhere and have standard
payment terms that generally require payment within 30 to 90 days.

Receivables from collaborations are recorded for amounts due to the Company related to reimbursable research and development costs from the U.S.

Department of Health and Human Services, and royalty receivables from our partners, including Shionogi, Green Cross, and Torii.

Monthly invoices are submitted to the U.S. Department of Health and Human Services related to reimbursable research and development costs. The
Company is also entitled to monthly reimbursement of indirect costs based on rates stipulated in the underlying contract. The Company’s calculations of its
indirect cost rates are subject to audit by the U.S. Government.

The Company does not adjust its receivables for the effects of a significant financing component at contract inception if it expects to collect the

receivables in one year or less from the time of sale.

The Company provides reserves against trade receivables for estimated losses that may result from a customer's inability to pay. Receivables are

evaluated to determine if any reserve or allowance should be recorded based on consideration of the current economic environment, expectations of future
economic conditions, specific circumstances and the Company’s own historical collection experience. Amounts determined to be uncollectible are charged
or written-off against the reserve.

Inventory

The Company values its inventories at the lower of cost or estimated net realizable value. The Company determines the cost of its inventories, which

includes amounts related to materials, labor, manufacturing overhead, and shipping and handling costs on a first-in, first-out (FIFO) basis. Raw materials
and work-in-process include all inventory costs prior to packaging and labelling, including raw material, active product ingredient, and the drug product.
Finished goods include packaged and labelled products.

The Company’s inventories are subject to expiration dating. The Company regularly evaluates the carrying value of its inventories and provides

valuation reserves for any estimated obsolete, short-dated or unmarketable inventories. In addition, the Company may experience spoilage of its raw
materials and supplies. The Company’s determination that a valuation reserve might be required, in addition to the quantification of such reserve, requires it
to utilize significant judgement.

The Company expenses costs related to the production of inventories as research and development expenses in the period incurred until such time it

is believed that future economic benefit is expected to be recognized, which generally is reliant upon receipt of regulatory approval. Upon regulatory
approval, the Company capitalizes subsequent costs related to the production of inventories.

Property and Equipment

Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets.

Computer equipment is depreciated over a life of three years. Laboratory equipment, office equipment, and software are depreciated over a life of five
years. Furniture and fixtures are depreciated over a life of seven years. Leasehold improvements are amortized over their estimated useful lives or the
expected lease term, whichever is less.

In accordance with U.S. GAAP, the Company periodically reviews its property and equipment for impairment when events or changes in

circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of
undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be
sufficient to recover the carrying amount of the assets, the assets are written down to their estimated fair values. Property and equipment to be disposed of
are reported at the lower of carrying amount or fair value less cost to sell.

Accrued Expenses

The Company generally enters into contractual agreements with third-party vendors who provide research and development, manufacturing,
distribution, and other services in the ordinary course of business. Some of these contracts are subject to milestone-based invoicing, and services are
completed over an extended period of time. The Company records liabilities under these contractual commitments when it determines an obligation has
been incurred, regardless of the timing of the invoice. This process involves reviewing open contracts and purchase orders, communicating with applicable
Company personnel to identify services that have been performed on its behalf and estimating the level of service performed and the associated cost
incurred for the service when the Company has not yet been invoiced or otherwise notified of actual cost. The majority of service providers invoice the
Company monthly in arrears for services performed. The Company makes estimates of accrued expenses as of each balance sheet date in its financial
statements based on the facts and circumstances. The Company periodically confirms the accuracy of its estimates with the service providers and makes
adjustments if necessary. Examples of estimated accrued expenses include (i) fees paid to clinical research organizations (“CROs”) in connection with
preclinical and toxicology studies and clinical trials; (ii) fees paid to investigative sites in connection with clinical trials; (iii) fees paid to contract
manufacturers in connection with the production of the Company’s raw materials, drug substance, drug products, and product candidates; and (iv)
professional fees.

The Company bases its expenses related to clinical trials on its estimates of the services received and efforts expended pursuant to contracts with

multiple research institutions and CROs that conduct and manage clinical trials on the Company’s behalf. The financial terms of these agreements are
subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors
such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, the Company estimates the time
period over which services will be performed and the level of effort expended in each period. If the actual timing of the performance of services or the level
of effort varies from the estimate, the Company will adjust the accrual accordingly. As of December 31, 2021 and December 31, 2020, the carrying value of
accrued expenses approximates their fair value due to their short-term settlement.

Cost of Product Sales

Cost of product sales includes the cost of producing and distributing inventories that are related to product revenue during the respective period,

including freight. In addition, shipping and handling costs for product shipments are recorded as incurred. Finally, cost of product sales may also include
costs related to excess or obsolete inventory adjustment charges.

Research and Development Expenses

The Company’s research and development costs are charged to expense when incurred. Research and development expenses include all direct and

indirect development costs related to the development of the Company’s portfolio of product candidates. Advance payments for goods or services that will
be used or rendered for future research and development activities are deferred and capitalized. Such amounts are recognized as expense when the related
goods are delivered or the related services are performed. Research and development expenses include, among other items, personnel costs, including
salaries and benefits, manufacturing costs, clinical, regulatory, and toxicology services performed by CROs, materials and supplies, and overhead
allocations consisting of various administrative and facilities related costs. Most of the Company’s manufacturing and clinical and preclinical studies are
performed by third-party CROs. Costs for studies performed by CROs are accrued by the Company over the service periods specified in the contracts, and
estimates are adjusted, if required, based upon the Company’s ongoing review of the level of services actually performed.

Additionally, the Company has license agreements with third parties, such as Albert Einstein College of Medicine of Yeshiva University

(“AECOM”), Industrial Research, Ltd. (“IRL”), and the University of Alabama at Birmingham (“UAB”), which require fees related to sublicense
agreements or maintenance fees. The Company expenses sublicense payments as incurred unless they are related to revenues that have been deferred, in
which case the expenses are deferred and recognized over the related revenue recognition period. The Company expenses maintenance payments as
incurred.

Deferred collaboration expenses represent sub-license payments, paid to the Company’s academic partners upon receipt of consideration from
various commercial partners, and other consideration paid to the Company’s academic partners for modification to existing license agreements. These
deferred expenses would not have been incurred without receipt of such payments or modifications from the Company’s commercial partners and are being
expensed in proportion to the related revenue being recognized. The Company believes that this accounting treatment appropriately matches expenses with
the associated revenue.

Selling, General and Administrative Expenses

Selling, general and administrative expense is primarily comprised of compensation and benefits associated with sales and marketing, finance,

human resources, legal, information technology and other administrative personnel. Additionally, selling, general and administrative expenses are
comprised of market research, marketing, advertising and legal expenses, including patent costs, licenses and other general and administrative costs,

Advertising expenses related to ORLADEYO were $5,705 and $6,567 for the years ended December 31, 2021 and 2020, respectively. The

Company did not incur advertising and product promotion expenses in 2019.

The Company seeks patent protection on all internally developed processes and products. All patent related costs are expensed to selling, general

and administrative expenses when incurred as recoverability of such expenditures is uncertain.

Leases

The Company leases certain assets under operating leases, which primarily consisted of real estate leases, laboratory equipment leases and office

equipment leases as of December 31, 2021. The Company accounts for lease obligations in accordance with ASU 2016-02: Leases (Topic 842), which
requires a lessee to recognize a right-of-use asset and a lease liability on its balance sheet for most operating leases.

Certain of the Company’s operating leases provide for renewal options, which can vary by lease. The right-of-use asset and lease liabilities on the
Company’s Consolidated Balance Sheet represent payments over the lease term, which includes renewal options for certain real estate leases that we are
likely to exercise. As part of the Company’s assessment of the lease term, the Company elected the hindsight practical expedient, which allows companies
to use current knowledge and expectations when determining the likelihood to extend lease options. Certain operating leases include rent escalation
provisions, which the Company recognizes as expense on a straight-line basis. Lease expense for leases with an initial term of twelve months or less was
not material.

The discount rate used in the calculation of the Company’s right-of-use asset and lease liability was determined based on the stated rate within each

contract when available, or the Company’s collateralized borrowing rate from lending institutions.

The Company has not made any residual value guarantees related to its operating leases; therefore, the Company has no corresponding liability

recorded on its Consolidated Balance Sheets.

Stock-Based Compensation

All share-based payments, including grants of stock option awards and restricted stock unit awards, are recognized in the Company’s Consolidated

Statements of Comprehensive Loss based on their fair values. The fair value of stock option awards is estimated using the Black-Scholes option pricing
model. The fair value of restricted stock unit awards is based on the grant date closing price of the common stock. Stock-based compensation cost is
recognized as expense on a straight-line basis over the requisite service period of the award. In addition, we have outstanding performance-based stock
options for which no compensation expense is recognized until “performance” is deemed to have occurred.

Interest Expense and Deferred Financing Costs

Interest expense for the years ended December 31, 2021, 2020 and 2019 was $59,294, $14,501 and $11,892, respectively, and primarily relates to
the royalty financing obligations and PhaRMA Notes (Note 8), the secured term loan borrowing from the Credit Agreement and the senior credit facility
(Note 9). Costs directly associated with the borrowings have been capitalized and are netted against the corresponding debt liabilities on the Consolidated
Balance Sheets. These costs are being amortized to interest expense over the terms of the corresponding borrowings using the effective interest rate
method. Amortization of deferred financing costs included in interest expense was $(531), $1,217 and $1,278 for the years ended December 31, 2021, 2020
and 2019, respectively.

In December 2021, the PhaRMA Notes and associated accrued interest payable was written-off into other income as a debt extinguishment (Refer to

Note 8, Non-Recourse Notes Payable – Debt Extinguishment for additional information regarding the debt extinguishment). In December 2020, the
outstanding principal balance of the senior credit facility was repaid and related unamortized deferred financing costs and original issue discount of $1,211
were fully expensed as part of loss on debt extinguishment.

Interest Expense and Royalty Financing Obligations

The royalty financing obligations are eligible to be repaid based on royalties from net sales of ORLADEYO, BCX9930, and another earlier stage
Factor D inhibitor. Interest expense is accrued using the effective interest rate method over the estimated period each of the related liabilities will be paid.
This requires the Company to estimate the total amount of future royalty payments to be generated from product sales over the life of the agreement. The
Company imputes interest on the carrying value of each of the royalty financing obligations and records interest expense using an imputed effective interest
rate. The Company reassesses the expected royalty payments each reporting period and accounts for any changes through an adjustment to the effective
interest rate on a prospective basis. The assumptions used in determining the expected repayment term of the debt and amortization period of the issuance
costs requires that the Company make estimates that could impact the carrying value of each of the liabilities, as well as the periods over which associated
issuance costs will be amortized. A significant increase or decrease in forecasted net sales could materially impact each of the liability balances, interest
expense and the time periods for repayment.

Currency Hedge Agreement

In connection with the issuance by JPR Royalty Sub LLC of the PhaRMA Notes, the Company entered into a Currency Hedge Agreement to hedge
certain risks associated with changes in the value of the Japanese yen relative to the U.S. dollar. The final tranche of the options under the Currency Hedge
Agreement expired in November 2020. The Currency Hedge Agreement did not qualify for hedge accounting treatment; therefore mark-to-market
adjustments were recognized in the Company’s Consolidated Statements of Comprehensive Loss.

Cumulative mark-to-market adjustments for the years ended December 31, 2020 and 2019 resulted in losses of $632 and $347, respectively. Mark-

to-market adjustments were determined by a third-party pricing model which uses quoted prices in markets that are not actively traded and for which
significant inputs are observable directly or indirectly, representing Level 2 in the fair value hierarchy as defined by U.S. GAAP. In addition, realized
currency exchange gains of $662 and $863 were recognized in 2020 and 2019, respectively, related to the exercise of a U.S. dollar/Japanese yen currency
option under the Company’s foreign currency hedge.

Income Taxes

The liability method is used in the Company’s accounting for income taxes. Under this method, deferred tax assets and liabilities are determined

based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are
expected to be in effect when the differences are expected to reverse.

Net Loss Per Share

Net loss per share is based upon the weighted average number of common shares outstanding during the period. Diluted loss per share is equivalent
to basic net loss per share for all periods presented herein because common equivalent shares from unexercised stock options, warrants and common shares
expected to be issued under the Company’s equity compensation plans were anti-dilutive. The calculation of diluted earnings per share for the years ended
December 31, 2021, 2020, and 2019 does not include 26,034, 14,957, and 2,805, respectively, of potential common shares as their impact would be anti-
dilutive.

Accumulated Other Comprehensive Income

Accumulated other comprehensive income is comprised of cumulative foreign currency translation adjustments and unrealized gains and losses on

available-for-sale investments and is disclosed as a separate component of stockholders’ equity. Realized gain and loss amounts on available-for-sale
investments are reclassified from accumulated other comprehensive loss and recorded as interest and other income on the Consolidated Statements of
Comprehensive Loss. For both the years ended December 31, 2021 and 2020, realized gains of $1 were reclassified out of accumulated other
comprehensive income.

Significant Customers and Other Risks

Significant Customers

The Company’s primary sources of revenue and cash flow are the sales of ORLADEYO to a specialty pharmacy, the reimbursement of galidesivir

(formerly BCX4430) development expenses earned under cost-plus-fixed-fee contracts with BARDA/HHS and NIAID/HHS and sales of RAPIVAB
(peramivir injection) under our procurement contract with the Assistant Secretary for Preparedness and Response within the United States Department of
Health and Human Services.

ORLADEYO is distributed through an arrangement with a single specialty pharmacy in the U.S. The specialty pharmacy subsequently sells
ORLADEYO to its customers (pharmacy benefit managers, insurance companies, government programs and group purchasing organizations) and
dispenses product to patients. The specialty pharmacy’s inability or unwillingness to continue these distribution activities could adversely impact the
Company’s business, results of operations and financial condition.

The Company relies on BARDA/HHS and NIAID/HHS to reimburse predominantly all of the development costs for its galidesivir program and

stockpiling sales of RAPIVAB to HHS. Accordingly, reimbursement of these expenses represents a significant portion of the Company’s collaborative and
other research and development revenues. Additionally, HHS is the primary customer for RABIVAB. The completion or termination of the NIAID/HHS
and BARDA/HHS galidesivir contracts or the reduction or stoppage of purchases of RAPIVAB by HHS could adversely impact the Company’s business,
results of operations and financial condition.

Further, the Company’s drug development activities are performed by a limited group of third-party vendors. If any of these vendors were unable to

perform its services, this could significantly impact the Company’s ability to complete its drug development activities.

Risks from Third-Party Manufacturing and Distribution Concentration

The Company relies on single source manufacturers for active pharmaceutical ingredient and finished drug product manufacturing of product

candidates in development and on a single specialty pharmacy for distribution of approved drug product in the US. Delays in the manufacture or
distribution of any product could adversely impact the commercial revenue and future procurement stockpiling of the Company’s product candidates.

Credit Risk

Cash equivalents and investments are financial instruments that potentially subject the Company to concentration of risk to the extent recorded on

the Consolidated Balance Sheets. The Company deposits excess cash with major financial institutions in the United States. Balances may exceed the
amount of insurance provided on such deposits. The Company believes it has established guidelines for investment of its excess cash relative to
diversification and maturities that maintain safety and liquidity. To minimize the exposure due to adverse shifts in interest rates, the Company maintains a
portfolio of investments with an average maturity of approximately 12 months or less.

The Company’s receivables from sales of ORLADEYO are primarily due from one customer, resulting in a concentration of credit risk. Sales of

ORLADEYO from the Company to the specialty pharmacy only occur once an order of product has been received by the specialty pharmacy from one of
its customers, which include pharmacy benefit managers, insurance companies, government programs and group purchasing organizations.

The majority of the Company’s receivables from collaborations are due from the U.S. Government, for which there is no assumed credit risk.

Recently Adopted Accounting Pronouncements

In December 2019, the FASB issued ASU No. 2019-12 (ASC Topic 740), Simplifying the Accounting for Income Taxes. ASU 2019-12 simplifies

accounting for income taxes by removing certain exceptions to the general principles and clarifying existing guidance. This standard is effective for fiscal
years, and interim periods within those years, beginning after December 15, 2020. The adoption of this standard did not have a material impact to the
Company’s financial position, results of operations or cash flows.

The Company has reviewed other new accounting pronouncements that were issued as of December 31, 2021 and does not believe that these

pronouncements are either applicable to the Company, or that they will have a material impact on its financial position or results of operations.

The following tables summarize the fair value of the Company’s investments by type. The estimated fair values of the Company’s fixed income
investments are classified as Level 2 in the fair value hierarchy as defined in U.S. GAAP. These valuations are based on observable direct and indirect
inputs, primarily quoted prices of similar, but not identical, instruments in active markets or quoted prices for identical or similar instruments in markets
that are not active. These fair values are obtained from independent pricing services which utilize Level 2 inputs.

On March 9, 2011, the Company completed a $30,000 financing transaction to monetize certain future royalty and milestone payments under the

Company’s agreement with Shionogi (the “Shionogi Agreement”), pursuant to which Shionogi licensed from the Company the rights to market
RAPIACTA in Japan and Taiwan. The Company received net proceeds of $22,691 from the transaction after transaction costs of $4,309 and the
establishment of a $3,000 interest reserve account by Royalty Sub, available to help cover interest shortfalls in the future. All of the interest reserve account
has been fully utilized with the September 2012 interest payment.

As part of the transaction, the Company entered into a purchase and sale agreement dated as of March 9, 2011 with JPR Royalty Sub, LLC, a
wholly-owned subsidiary of the Company (“Royalty Sub”), whereby the Company transferred to Royalty Sub, among other things, (i) its rights to receive
certain royalty and milestone payments from Shionogi arising under the Shionogi Agreement, and (ii) the right to receive payments under a Japanese
yen/US dollar foreign currency hedge arrangement (as further described below, the “Currency Hedge Agreement”) put into place by the Company in
connection with the transaction. Royalty payments are paid by Shionogi in Japanese yen, and any milestone payments will be paid in U.S. dollars. The
Company’s collaboration with Shionogi was not impacted as a result of this transaction.

Non-Recourse Notes Payable

On March 9, 2011, Royalty Sub completed a private placement to institutional investors of $30,000 in aggregate principal amount of its PhaRMA

Senior Secured 14.0% Notes due on December 1, 2020 (the “PhaRMA Notes”). The PhaRMA Notes were issued by Royalty Sub under an Indenture, dated
as of March 9, 2011 (the “Indenture”), by and between Royalty Sub and U.S. Bank National Association, as Trustee. Principal and interest on the PhaRMA
Notes issued are payable from, and are secured by, the rights to royalty and milestone payments under the Shionogi Agreement transferred by the Company
to Royalty Sub and payments, if any, made to Royalty Sub under the Currency Hedge Agreement. The PhaRMA Notes bear interest at 14% per annum,
payable annually in arrears on September 1st of each year. The Company remains entitled to receive any royalties and milestone payments related to sales
of peramivir by Shionogi following repayment of the PhaRMA Notes.

Royalty Sub’s obligations to pay principal and interest on the PhaRMA Notes are obligations solely of Royalty Sub and are without recourse to any
other person, including the Company, except to the extent of the Company’s pledge of its equity interests in Royalty Sub in support of the PhaRMA Notes.
The Company may, but is not obligated to, make capital contributions to a capital account that may be used to redeem, or on up to one occasion pay any
interest shortfall on, the PhaRMA Notes.

In September 2014, Royalty Sub was unable to pay the accrued interest obligation due September 3, 2013. Under the terms of the Indenture, Royalty

Sub’s inability to pay the full amount of interest payable in September 2013 by the next succeeding payment date for the PhaRMA Notes, which was
September 1, 2014, constituted an event of default. Accordingly, the PhaRMA Notes and related accrued interest have been classified as current liabilities
on the December 31, 2014 balance sheet, and thereafter. As a result of the event of default under the PhaRMA Notes, the holders of the PhaRMA Notes
may foreclose on the collateral securing the PhaRMA Notes and the equity interest in Royalty Sub and exercise other remedies available to them under the
Indenture in respect of the PhaRMA Notes. In such event, the Company may not realize the benefit of future royalty payments that might otherwise accrue
to it following repayment of the PhaRMA Notes and it might otherwise be adversely affected. Due to the non-recourse nature of the PhaRMA Notes, in the
event of any potential foreclosure, the primary impact to the Company would be the loss of future royalty payments, if any, from Shionogi and legal costs
associated with retiring the PhaRMA Notes. The PhaRMA Notes had a final legal maturity date of December 1, 2020, at which time the outstanding
principal amount of the PhaRMA Notes of $30,000, together with accrued and unpaid interest of $20,614, was due in full.

Non-Recourse Notes Payable – Debt Extinguishment

During 2021, the royalty-bearing patents associated with RAPIACTA in Japan expired.  Accordingly, the Company evaluated the current
circumstances of the PhaRMA Notes, including (i) their non-recourse nature relative to the Company, (ii) the current state of default since September 1,
2014 and the legal maturity on December 1, 2020 and (iii) the loss of patent protection relative to RAPIACTA in Japan, upon which any significant
repayment of the PhaRMA Notes is predicated.  As a result, the Company determined that it was no longer the financial obligor, and as a result, the
principal balance of $30,000 and associated accrued interest payable balance of $25,838 were written off, resulting in a gain on extinguishment recorded in
other income (expense) for the year ended December 31, 2021.

ORLADEYO and Factor D Inhibitors

On December 7, 2020, the Company and RPI 2019 Intermediate Finance Trust (“RPI”) entered into a Purchase and Sale Agreement (the “2020 RPI
Royalty Purchase Agreement”), pursuant to which the Company sold to RPI the right to receive certain royalty payments from the Company for a purchase
price of $125,000 in cash (the “2020 RPI Royalty Sale”).  Under the 2020 RPI Royalty Purchase Agreement, RPI is entitled to receive tiered, sales-based
royalties on net product sales of ORLADEYO in the United States and certain key European markets (collectively, the “Key Territories”), and other
markets where the Company sells ORLADEYO directly or through distributors (collectively, the “Direct Sales”) in an amount equal to: (i) 8.75% of
aggregate annual net sales of ORLADEYO for annual net sales up to $350,000 and (ii) 2.75% of annual net sales for annual net sales between $350,000
and $550,000. No royalty payments are payable on annual Direct Sales over $550,000.  In addition, RPI will be entitled to receive 1.0% of global net sales,
if any, of BCX9930.

Under the 2020 RPI Royalty Purchase Agreement, RPI is also entitled to receive a tiered revenue share on ORLADEYO sublicense revenue or net
sales by licensees outside of the Key Territories (the “Other Markets”) equal to: (i) 20% of the proceeds received by the Company for upfront license fees
and development milestones for ORLADEYO in the Other Markets; (ii) 20% of proceeds received on annual net sales of up to $150,000 in the Other
Markets; and (iii) 10% of proceeds received by the Company on annual net sales between $150,000 and $230,000 in the Other Markets. No royalty
payments are payable on annual net sales above $230,000 in the Other Markets.

On November 19, 2021, the Company and RPI entered into (i) a Purchase and Sale Agreement (the “2021 RPI Royalty Purchase Agreement” and

together with the 2020 RPI Royalty Purchase Agreement, the “RPI Royalty Purchase Agreements”), pursuant to which the Company sold to RPI the right
to receive certain royalty payments from the Company for a purchase price of $150,000 in cash, and (ii) a Purchase and Sale Agreement with OCM IP
Healthcare Holdings Limited, an affiliate of OMERS Capital Markets (“OMERS”) (the “OMERS Royalty Purchase Agreement” and collectively with the
RPI Royalty Purchase Agreements, the “Royalty Purchase Agreements”), pursuant to which the Company sold to OMERS the right to receive certain
royalty payments from the Company for a purchase price of an additional $150,000 in cash.

Under the 2021 RPI Royalty Purchase Agreement, RPI is entitled to receive tiered, sales-based royalties on Direct Sales in an amount equal to: (i)

0.75% of aggregate annual net sales of ORLADEYO for annual net sales up to $350,000 and (ii) 1.75% of annual net sales of ORLADEYO for annual net
sales between $350,000 and $550,000. No royalty payments are payable on Direct Sales over $550,000. RPI is also entitled to receive a tiered revenue
share on ORLADEYO sublicence revenue or net sales by licensees in the Other Markets in an amount equal to 3.0% of proceeds received by the Company
on annual net sales of up to $150,000 in the Other Markets, and (iii) 2.0% of proceeds received by the Company on annual net sales between $150,000 and
$230,000 in the Other Markets. No royalty payments are payable on annual net sales above $230,000 in the Other Markets.

Under the 2021 RPI Royalty Purchase Agreement, RPI is also entitled to receive tiered, sales-based royalties on net product sales of BCX9930 and

another earlier stage Factor D inhibitor in an amount equal to: (i) 3.0% of worldwide aggregate annual net sales up to $1.5 billion and (ii) 2.0% of
worldwide aggregate annual net sales between $1.5 billion and $3.0 billion. No royalty payments are payable on annual net sales above $3.0 billion. RPI is
also entitled to receive tiered profit share amounts of up to 3.0% from certain other permitted sales in certain other markets.

The royalties payable under the 2021 RPI Royalty Purchase Agreement are in addition to the royalties payable to RPI under the 2020 RPI Royalty

Purchase Agreement.

Under the OMERS Royalty Purchase Agreement, commencing with the calendar quarter beginning October 1, 2023, OMERS will be entitled to
receive tiered, sales-based royalties on Direct Sales in an amount equal to: (i) 7.5% of aggregate annual net sales of ORLADEYO for annual net sales up to
$350,000 and (ii) 6.0% of annual net sales of ORLADEYO for annual net sales between $350,000 and $550,000 (with no royalty payments payable on
annual Direct Sales over $550,000) (the “Regime A Royalty Rate”). If annual Direct Sales for calendar year 2023 reach a specified amount set forth in the
OMERS Royalty Purchase Agreement, then for each calendar quarter beginning on or after January 1, 2024, OMERS will be entitled to receive the Regime
A Royalty Rate. If annual Direct Sales for calendar year 2023 are less than the specified amount, OMERS will be entitled to receive tiered, sales-based
royalties on Direct Sales in an amount equal to: (i) 10.0% of aggregate annual net sales of ORLADEYO for annual net sales up to $350,000 and (ii) 3.0%
of annual net sales of ORLADEYO for annual net sales between $350,000 and $550,000 (with no royalty payments payable on annual Direct Sales over
$550,000) (the “Regime B Royalty Rate”).

71

 
 
 
 
 
 
 
 
 
 
 
 
 
Under the OMERS Royalty Purchase Agreement, OMERS is also entitled to receive a tiered revenue share on ORLADEYO sublicense revenue or

net sales by licensees in the Other Markets in an amount equal to: (i) 20.0% of the proceeds received by the Company for upfront license fees and
development milestones for ORLADEYO in the Other Markets, (ii) 20.0% of proceeds received by the Company on annual net sales of up to $150,000 in
the Other Markets, and (iii) 10.0% of proceeds received by the Company on annual net sales between $150,000 and $230,000 in the Other Markets. No
royalty payments are payable on annual net sales above $230,000 in the Other Markets. OMERS is also entitled to receive profit share amounts of up to
10% from certain other permitted sales in certain other markets.

Under the 2020 RPI Royalty Purchase Agreement, the Company is required to make royalty payments of amounts owed to RPI each calendar
quarter following the first commercial sale of ORLADEYO in any country. Under the 2021 RPI Royalty Purchase Agreement, the Company is required to
make payments to RPI in respect of net sales or sublicense revenue in each calendar quarter from and after October 1, 2021. Under the OMERS Royalty
Purchase Agreement, the Company will be required to make payments to OMERS is respect of net sales or sublicense revenue in each calendar quarter
from and after October 1, 2023. OMERS will no longer be entitled to receive any payments on the date in which aggregate payments actually received by
OMERS equals either 142.5% or 155.0% of the $150,000 purchase price, depending on sales levels in calendar year 2023.

The transactions contemplated by each of the Royalty Purchase Agreements are referred to herein as the “Royalty Sales.”

Under the Royalty Purchase Agreements, the Company has agreed to specified affirmative and negative covenants, including covenants regarding
periodic reporting of information by the Company to RPI and OMERS, third-party audits of royalties paid under the Royalty Purchase Agreements, and
restrictions on the ability of the Company or any of its subsidiaries to incur indebtedness other than certain royalty sales and as is permitted to be incurred
under the terms of the Company’s Credit Agreement with Athyrium Opportunities III Co-Invest 1 LP. Refer to Note 9 for further details on the Credit
Agreement. The restrictions on the ability of the Company or any of its subsidiaries to incur indebtedness are eliminated after the achievement of certain
specified milestones in the Royalty Purchase Agreements.

The cash consideration obtained pursuant to the Royalty Purchase Agreements is recorded in “Royalty financing obligations” on the Company’s
consolidated balance sheet. The fair value for the royalty financing obligations at the time of the transactions was based on the Company’s estimates of
future royalties expected to be paid to the counterparty over the life of the arrangement. The Company subsequently records the obligations at its carrying
value using the effective interest method. In order to amortize the royalty financing obligation, the Company utilizes the prospective method to estimate the
future royalties to be paid by the Company to the counterparty over the life of the arrangement. Under the prospective method, a new effective interest rate
is determined based on the revised estimate of remaining cash flows. The new rate is the discount rate that equates the present value of the revised estimate
of remaining cash flows with the carrying amount of the debt, and it will be used to recognize interest expense for the remaining periods. The Company
periodically assesses the amount and timing of expected royalty payments using a combination of internal projections and forecasts from external sources.
The estimates of future net product sales (and resulting royalty payments) are based on key assumptions including population, penetration, probability of
success, and sales price, among others. To the extent such payments are greater or less than the Company’s initial estimates or the timing of such payments
is materially different than its original estimates, the Company will prospectively adjust the amortization of the royalty financing obligations and the
effective interest rate.

using the effective interest method over the term of the arrangement, in accordance with the respective guidance.  Concurrent with entering into the 2021
RPI Royalty Purchase Agreement, the Company and RPI entered into a Common Stock Purchase Agreement, pursuant to which the Company sold
common stock to RPI for a premium of $4,269.  This premium has been deferred and is being amortized using the effective interest method over the term
of the applicable arrangement. Refer to Note 11 for further details on the common stock sale premium.

Note 9 — Debt

Credit Agreement

On December 7, 2020, the Company entered into a $200,000 Credit Agreement with Athyrium Opportunities III Co-Invest 1 LP (“Athyrium”), as

lender and as administrative agent for the lenders. BioCryst Ireland Limited and BioCryst US Sales Co., LLC, each of which is a wholly-owned subsidiary
of the Company, and BioCryst UK Limited, a wholly-owned subsidiary of BioCryst Ireland Limited, are guarantors to the Credit Agreement. The Credit
Agreement provides for an initial term loan in the principal amount of $125,000 (the “Term A Loan”), which was received by the Company on December
7, 2020 and is recorded in “Secured term loan” on the Company’s balance sheet as of December 31, 2021.  The Company used a portion of the proceeds
from the Term A Loan to repay $43,298 of outstanding indebtedness, including accrued interest, under its existing credit facility with MidCap Financial
Trust.

The Credit Agreement also provides for two additional term loans, at the Company's option, in the respective principal amounts of $25,000 (the

“Term B Loan”) and $50,000 (the “Term C Loan”).  The Term B Loan and the Term C Loan may be drawn upon if, among other conditions, the Company
reaches defined revenue milestones and, with respect to a draw on the Term C Loan, the Term B Loan has been funded prior to or contemporaneously with
the Term C Loan.  The maturity date of the Credit Agreement is December 7, 2025.

On November 19, 2021, the Company entered into an amendment to the Credit Agreement (i) to permit the Company to enter into the 2021 RPI

Royalty Purchase Agreement, the OMERS Royalty Purchase Agreement, and the other definitive documentation related thereto and to perform its
obligations thereunder; (ii) to require the Company to pay to Athyrium, for the account of the lenders, a make-whole premium plus certain fees set forth in
the Credit Agreement in the event that the Company does not draw the Term B Loan or the Term C Loan, as applicable, by the end of the applicable period
available to draw the Term B Loan or the Term C Loan, subject to certain exceptions set forth in the Credit Agreement; and (iii) to require the Company to
pay to Athyrium, for the account of the lenders, a make-whole premium plus certain fees set forth in the Credit Agreement in the event that the Company
either (x) terminates the commitments in respect of the Term B Loan or the Term C Loan, as applicable, on or prior to the end of the applicable period
available to draw the Term B Loan or the Term C Loan, or (y) prepays or repays, or is required to prepay or repay, voluntarily or pursuant to mandatory
prepayment obligation under the Credit Agreement (e.g., with the proceeds of certain asset sales, certain ORLADEYO out-licensing or royalty
monetization transactions (excluding the Royalty Sales), extraordinary receipts, debt issuances, or upon a change of control of the Company and specified
other events, subject to certain exceptions), all of the then-outstanding Term Loans, in each case, subject to certain exceptions set forth in the Credit
Agreement.

The Credit Agreement provides for quarterly interest-only payments until the maturity date, with the unpaid principal amount of the outstanding

Term Loans due and payable on the maturity date.  For each of the first eight full fiscal quarters following December 7, 2020, the Company has the option
to make the applicable interest payment-in-kind (a “PIK Interest Payment”) by capitalizing the entire amount of interest accrued during the applicable
interest period with the unpaid original principal amount outstanding on the last day of such period. The Term Loans will bear interest at a rate equal to the
three-month LIBOR rate, which shall be no less than 1.75% and no more than 3.50% (“LIBOR”), plus 8.25%, or for each interest period in which a PIK
Interest Payment is made, the LIBOR plus 10.25%.

Subject to certain exceptions, the Company is required to make mandatory prepayments of the Term Loans with the proceeds of certain asset sales,

certain ORLADEYO out-licensing or royalty monetization transactions (excluding the Royalty Sale), extraordinary receipts, debt issuances, or upon a
change of control of the Company and specified other events, subject to certain exceptions. The Company may make voluntary prepayments in whole or in
part. Prepayments are subject to a premium equal to, (i) with respect to any voluntary prepayment and certain mandatory prepayments paid on or prior to
the second anniversary of the applicable Term Loan borrowing date, the amount, if any, by which (a) the sum of (1) 102.00% of the principal amount of the
Term Loan being prepaid plus (2) the present value of all interest that would have accrued on the principal amount of the Term Loan being prepaid through
and including the second anniversary of the date of the borrowing of such Term Loan, plus 0.50%, exceeds (b) the principal amount of the Term Loan being
prepaid; (ii) with respect to any prepayment made between the second and third anniversaries of the applicable Term Loan borrowing date, 2.00% of the
principal amount of the Term Loan being prepaid; (iii) with respect to any prepayment made between the third and fourth anniversaries of the applicable
Term Loan borrowing date, 1.00% of the principal amount of the Term Loan being prepaid; and (iv) with respect to any prepayment made after the fourth
anniversary of the applicable Term Loan borrowing date, 0.00% of the principal amount of the Term Loan being prepaid. Upon the prepayment or
repayment, including at maturity, of all or any of the Term Loans, the Company is obligated to pay an exit fee in an amount equal to 2.00% of the principal
amount of the Term Loans prepaid or repaid. In addition, each Term Loan is subject to a 1.00% commitment fee at its respective borrowing date.

The Credit Agreement also contains representations and warranties and affirmative and negative covenants customary for financings of this type, as
well as customary events of default.  Certain of the customary negative covenants limit the ability of the Company and certain of its subsidiaries to, among
other things, grant liens, make investments, incur additional indebtedness, engage in mergers, acquisitions, and similar transactions, dispose of assets,
license certain property, distribute dividends, make certain restricted payments, change the nature of the Company's business, engage in transactions with
affiliates and insiders, prepay other indebtedness, or engage in sale and leaseback transactions, subject to certain exceptions.  Additionally, as of the last day
of each fiscal quarter (a “Test Date”), beginning with the first Test Date occurring immediately after the Term C Loan is drawn, if applicable, the Company
may not permit consolidated net revenues from ORLADEYO sales in the United States for the four-fiscal quarter period ending on such Test Date to be
less than the specified amounts set forth in the Credit Agreement (collectively, the “Revenue Tests”).  If the Company fails to satisfy the Revenue Tests as
of any Test Date, it will have a one-time right (the “Cure Right”) to repay in full the entire amount of the Term C Loans outstanding at such time together
with all accrued and unpaid interest thereon plus the prepayment premium, exit fee, and any other fees or amounts payable under the Credit Agreement at
such time.  In addition, the Credit Agreement contains a minimum liquidity covenant requiring the Company to maintain at all times, as applicable, at least
$15,000 of unrestricted cash and cash equivalents if only the Term A Loan has been drawn; at least $20,000 of unrestricted cash and cash equivalents if the
Term B Loan has been drawn but the Term C Loan has not been drawn; and at least $15,000 (or, if the Cure Right has been exercised, $20,000) of
unrestricted cash and cash equivalents if the Term C Loan has been drawn, subject to certain exceptions.

73

 
 
 
 
 
 
 
 
 
 
 
A failure to comply with the covenants in the Credit Agreement could permit the Lenders under the Credit Agreement to declare the outstanding

principal as well as accrued interest and fees, to be immediately due and payable.

The Company's obligations under the Credit Agreement are secured by a security interest in, subject to certain exceptions, substantially all of the

Company's assets.

As of December 31, 2021, the Company had borrowings of $125,000 under the Credit Agreement. Quarterly interest payments under the Credit
Agreement for the years ended December 31, 2021 and 2020, totaled $16,009 and $1,056, respectively, and have been designated and accounted for as PIK
Interest Payments and added to the outstanding principal balance of the borrowing.  As of December 31, 2021, borrowings, including the PIK Interest
Payments totaled $142,065.  The principal balance of the borrowing, including PIK amounts are accruing interest at a rate of 12.17%. The fair value of the
debt approximates its carrying value based on prevailing interest rates as of the balance sheet date and is considered as Level 2 in the fair value hierarchy.

As of December 31, 2021 and 2020, deferred debt fees and issuance costs totaled $8,483 and $7,764, respectively and are being amortized as interest

expense on an effective interest rate method over the term of the Term A Loan. When utilizing the effective interest method, in periods in which PIK
interest is designated and those amounts are added to the outstanding principal balance of the borrowing, the amortization of the deferred debt fees and
issuance costs is accretive. Deferred financing amortization of ($531) and ($131), was recognized for the years ended December 31, 2021 and 2020,
respectively.

The Credit Agreement contains two provisions that, if deemed probable, would create the recognition of an embedded feature; however, at this time,

the Company does not believe either provision is probable.

Senior Credit Facility

On February 5, 2019, the Company entered into a $100,000 Senior Credit Facility with an affiliate of MidCap Financial Services, LLC, as
administrative agent (the “Second Amended and Restated Senior Credit Facility”). Borrowings under the Second Amended and Restated Senior Credit
Facility were available in three tranches, with (i) the first tranche comprised of $50,000 funded at closing, which included $30,000 of proceeds that were
deemed rolled over from the outstanding principal amount under the Company’s prior credit agreement, (ii) the second tranche comprised of $30,000, and
(iii) the third tranche comprised of $20,000, with the second and third tranches to have been funded upon the completion of certain contingencies related to
the Company’s development activities of its product candidates and the establishment of certain financial covenants. On September 10, 2019 the Company
executed the first amendment to the Second Amended and Restated Credit Facility which extended the commitment termination date for the second tranche
to November 30, 2019. On November 30, 2019, the Company’s access to the second tranche expired.

The Second Amended and Restated Senior Credit Facility refinanced and replaced the Amended and Restated Senior Credit Facility dated as of July

20, 2018 (the “Amended and Restated Senior Credit Facility”). The Second Amended and Restated Senior Credit Facility had a variable interest rate of
LIBOR (which was not to be less than 0.5%) plus 8%. The Second Amended and Restated Senior Credit Facility included an interest-only payment period
through June 2020 and scheduled monthly principal and interest payments for the subsequent 30 months. The Company used a portion of the proceeds of
the Second Amended and Restated Senior Credit Facility to pay off outstanding amounts under the Amended and Restated Senior Credit Facility and the
remainder was used for general corporate purposes.

In December 2020, the Company repaid the outstanding principal of the Second Amended and Restated Senior Credit Facility of $40,000 along with

exit fees and accrued interest through the payoff date that totaled $3,298. The unamortized deferred financing cost and original issue discount of $1,211
was expensed as a loss on debt extinguishment.

Note 10 — Lease Obligations

The Company leases certain assets under operating leases, which primarily consisted of real estate leases, laboratory equipment leases and office

equipment leases as of December 31, 2021. Renewal options for our leases range from 1 to 5 years in length and begin from 2023 through 2026. The
weighted average lease term for the Company’s operating leases was 9.2 years. The weighted average discount rate for the Company’s operating leases was
11.2%.

Aggregate lease expense under operating leases was $1,795 and $1,754 for the years ended December 31, 2021 and 2020, respectively.

On November 18, 2019, the Company completed an underwritten public offering of 43,621 shares of its common stock, offered at a price to the

public of $1.45 per share, including shares issued pursuant to the underwriters’ 30-day option to purchase additional shares, which was exercised in full.
The net proceeds from this offering were approximately $58,500 after deducting underwriting discounts and commissions and estimated offering expenses.

On November 21, 2019, the Company completed an offering of pre-funded warrants to purchase up to 11,765 shares of its common stock at a price

of $1.69 per warrant. Each pre-funded warrant is exercisable subject to conditions in the warrant agreement into 1 share of common stock at an exercise
price of $0.01 per share. The net proceeds from this offering were $19,882, excluding any proceeds the Company may receive upon the subsequent
exercise of the pre-funded warrants. All warrants issued in this offering remain outstanding at December 31, 2021.

On April 24, 2020, the Company filed a $500,000 shelf registration statement on Form S-3 with the SEC. This shelf registration statement became

effective on May 14, 2020 and allows the Company to sell securities, including common stock, preferred stock, depositary shares, purchase contracts,
warrants, debt securities, and units, from time to time at prices and on terms to be determined at the time of sale.

On June 1, 2020, the Company issued 22,044 shares of common stock to the public at a purchase price of $4.50 per share and pre-funded warrants to

purchase 3,511 shares of common stock at a purchase of $4.49 per pre-funded warrant, for total net proceeds to the Company of $108,096 million after
deducting underwriting discounts and commissions and other offering expenses. Each pre-funded warrant is exercisable subject to conditions in the warrant
agreement into 1 share of common stock at an exercise price of $0.01 per share. All warrants issued in this offering remain outstanding at December 31,
2021.

On March 1, 2021, the Company filed an automatic shelf registration statement on Form S-3 with the SEC. This shelf registration statement became

effective automatically upon filing and allows the Company to sell an indeterminate number of securities, including common stock, preferred stock,
depositary shares, purchase contracts, warrants, debt securities, and units, from time to time at prices and on terms to be determined at the time of sale.

On November 19, 2021, concurrent with the Company entering into the 2021 RPI Royalty Purchase Agreement, the Company and RPI entered into
a Common Stock Purchase Agreement, pursuant to which the Company issued 3,846,154 shares of the Company’s common stock to RPI for an aggregate
purchase price of $50,000, at a price of $13.00 per share, calculated based on the 20-day volume weighted average price. The $13.00 per share price
represents a premium of $1.11 over the closing price of $11.89 of the Company’s common stock on November 17, 2021, the last trading day prior to the
execution of the Common Stock Purchase Agreement. The premium of $4,269 paid by RPI on the purchase of the Company’s common stock has been
deferred and is being amortized as a component of interest expense of the 2021 RPI royalty financing obligation.

The Company grants stock option awards, restricted stock and restricted stock units to its employees, directors, and consultants under the Incentive

Plan. Under the Incentive Plan, stock option awards are granted with an exercise price equal to the market price of the Company’s stock at the date of grant.
Commencing March 1, 2011, stock option awards and restricted stock units granted to employees generally vest 25% each year until fully vested after four
years.

In August 2013, December 2014 and December 2019, the Company issued 1,032, 1,250 and 315 performance-based stock options, respectively.

These awards vest upon successful completion of specific development milestones. As of December 31, 2021, 100%, 85% and 100% of the August 2013,
December 2014 and December 2019 grants, respectively, have vested. During 2020, the Company recognized $1,768 and $684 of stock compensation
expense related to milestones within the August 2013 and December 2019 grants for which achievement became probable.

Stock option awards granted to non-employee directors of the Company generally vest over one year. Stock option awards granted to new non-

employee directors when they first join the Company’s Board of Directors generally vest, subject to the terms of the Incentive Plan, in 36 equal monthly
installments over a three-year period measured from the grant date.

All stock option awards have contractual terms of 10 years. The vesting exercise provisions of all awards granted under the Incentive Plan are
subject to acceleration in the event of certain stockholder-approved transactions, or upon the occurrence of a change in control as defined in the Incentive
Plan.

For stock option awards granted under the Incentive Plan during 2021, 2020, and 2019, the fair value was estimated on the date of grant using a
Black-Scholes option pricing model and the assumptions noted in the table below. The weighted average grant date fair value of these awards granted
during 2021, 2020, and 2019 was $7.93, $5.48, and $2.63, respectively. The fair value of the stock option awards is amortized to expense over the vesting
periods using a straight-line expense attribution method. For restricted stock units granted under the Incentive Plan, the fair value of the awards was
determined based on the market value of the Company’s shares on the grant date. The weighted average grant date fair value of these awards was $11.36.
The fair value of the restricted stock unit awards is amortized to expense over the vesting periods using a straight-line expense attribution method.

Inducement Equity Incentive Plan

The Company has the ability to grant stock option awards to newly-hired employees as inducements material to each employee entering employment

with the Company. Stock option awards granted to newly hired employees generally vest 25% each year until fully vested after four years. Each stock
option has a term of 10 years and is subject to the terms and conditions of the Inducement Plan. The vesting and exercise provisions of all awards granted
under the Inducement Plan are subject to acceleration in the event of certain stockholder-approved transactions, or upon the occurrence of a change in
control as defined in the Inducement Plan.

For stock option awards granted under the Inducement Plan during 2021, 2020, and 2019, the fair value was estimated on the date of grant using a

Black-Scholes option pricing model and the assumptions noted in the table below. The weighted average grant date fair value of these awards granted
during 2021, 2020, and 2019 was $9.65, $2.73, and $2.41, respectively. The fair value of the stock option awards is amortized to expense over the vesting
periods using a straight-line expense attribution method.

The following table summarizes the key assumptions used by the Company to value the stock option awards granted under all plans during 2021,

2020, and 2019, respectively. The expected life is based on the average of the assumption that all outstanding stock option awards will be exercised at full
vesting and the assumption that all outstanding stock option awards will be exercised at the midpoint of the current date (if already vested) or at full vesting
(if not yet vested) and the full contractual term. The expected volatility represents the historical volatility on the Company’s publicly traded common stock.
The Company has assumed no expected dividend yield, as dividends have never been paid to stock or option holders and will not be paid for the
foreseeable future. The weighted average risk-free interest rate is the implied yield currently available on zero-coupon government issues with a remaining
term equal to the expected term.

The total intrinsic value of stock option awards exercised under the Incentive Plan was $25,484 during 2021, $1,562 during 2020, and $1,127 during

2019. The intrinsic value represents the total proceeds (fair market value at the date of exercise, less the exercise price, times the number of stock option
awards exercised) received by all individuals who exercised stock option awards during the period. The total intrinsic value of stock option awards
exercised under the Inducement Plan was $6,700 during 2021. No stock option awards were exercised under the Inducement Plan in 2020.

Employee Stock Purchase Plan

The Company has reserved a total of 7,975 shares of common stock to be purchased under the ESPP, of which 6,052 shares remain available for

purchase at December 31, 2021. Eligible employees may authorize up to 15% of their salary to purchase common stock at the lower of 85% of the
beginning or 85% of the ending price during six-month purchase intervals. No more than 3 shares may be purchased by any one employee at the six-month
purchase dates and no employee may purchase stock having a fair market value at the commencement date of $25 or more in any one calendar year.

There were 321, 246, and 115 shares of common stock purchased under the ESPP in 2021, 2020, and 2019, respectively, at a weighted average price

per share of $6.20, $2.56, and $3.51, respectively. Expense of $1,523, $362, and $232 related to the ESPP was recognized during 2021, 2020, and 2019,
respectively. Compensation expense for shares purchased under the ESPP related to the purchase discount and the “look-back” option were determined
using a Black-Scholes option pricing model. The weighted average grant date fair values of shares granted under the ESPP during 2021, 2020, and 2019,
were $2.80, $1.47, and $2.01, respectively.

The Company recognizes the impact of a tax position in its financial statements if it is more likely than not that the position will be sustained on

audit based on the technical merits of the position. The Company has concluded that it has an uncertain tax position pertaining to its research and
development and orphan drug credit carryforwards. The Company has established these credits based on information and calculations it believes are
appropriate and the best estimate of the underlying credit. Any changes to the Company’s unrecognized tax benefits are offset by an adjustment to the
valuation allowance and there would be no impact on the Company’s financial statements. The Company does not expect its unrecognized tax benefits to
change significantly over the next 12 months.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

The Company’s ability to utilize the net operating loss and tax credit carryforwards in the future may be subject to substantial restrictions in the

event of past or future ownership changes as defined in Section 382 of the Internal Revenue Code of 1986, as amended and similar state tax law.

The majority of the Company’s deferred tax assets relate to net operating loss and research and development carryforwards that can only be realized
if the Company is profitable in future periods. It is uncertain whether the Company will realize any tax benefit related to these carryforwards. Accordingly,
the Company has provided a valuation allowance against substantially all the net deferred tax assets due to uncertainties as to their ultimate realization. The
valuation allowance will remain at the full amount of the deferred tax assets until it is more likely than not that the related tax benefits will be realized. The
Company’s valuation allowance increased by $47,954, $38,551, and $23,824 in 2021, 2020, and 2019, respectively.

As of December 31, 2021, the Company had U.S. federal operating loss carryforwards of $480,331, state operating loss carryforwards of $177,567,
foreign net operating losses of $29,355, and U.S. research and development and orphan drug credit carryforwards of $80,925, which will expire at various
dates from 2022 through 2041. Federal losses, state losses, research and development credit carryforwards began expiring in 2020. The foreign net
operating losses have an indefinite carryforward period.

Tax years 2018-2021 remain open to examination by the major taxing jurisdictions to which the Company is subject. Additionally, years prior to

2017 are also open to examination to the extent of loss and credit carryforwards from those years. The Company recognizes interest and penalties accrued
related to unrecognized tax benefits as components of its income tax provision. However, there were no provisions or accruals for interest and penalties in
2021, 2020 and 2019.

As of December 31, 2021, the Company has accumulated undistributed earnings of $750, generated by our foreign subsidiaries which have already

been subject to local and U.S. tax (as part of the GILTI provisions). We intend to indefinitely reinvest these earnings, as well as future earnings from our
foreign subsidiaries to fund out international operations. In addition, we expect future U.S. cash generation will be sufficient to meet future U.S cash needs.

Note 14 — Employee 401(k) Plan

In January 1991, the Company adopted an employee retirement plan (“401(k) Plan”) under Section 401(k) of the Internal Revenue Code covering all

employees. Employee contributions may be made to the 401(k) Plan up to limits established by the Internal Revenue Service. Company matching
contributions may be made at the discretion of the Board of Directors. The Company made matching contributions of $2,834, $1,569, and $926 in 2021,
2020, and 2019, respectively.

Note 15 — Collaborative and Other Relationships

National Institute of Allergy and Infectious Diseases (“NIAID/HHS”). In September 2013, NIAID/HHS contracted with the Company for the
development of galidesivir as a treatment for Marburg virus disease and subsequently, Yellow Fever and Ebola virus disease. On September 15, 2021, the
Company entered into an amendment to pay for certain additional costs, including additional manufacturing development costs and overhead, and to
change the total value of the contract, as amended, to $47,315 from $45,931. This is the commencement of closing out the contract. All options under the
contract have been awarded.

In August 2020, NIAID/HHS awarded the Company a new contract, with potential aggregate funding up of to $43,908 if all contract options are
exercised, to manufacture and evaluate the safety, efficacy and tolerability of galidesivir. NIAID/HHS made an initial award of $6,326 to the Company
under this contract.

Biomedical Advanced Research and Development Authority (“BARDA/HHS”). In March 2015, BARDA/HHS awarded the Company a contract for

the continued development of galidesivir as a potential treatment for diseases caused by RNA pathogens, including filoviruses. This BARDA/HHS contract
includes a base contract of $16,265 to support galidesivir drug manufacturing, as well as $22,855 in additional development options that can be exercised
by the government, bringing the potential value of the contract to $39,120. As of December 31, 2021, a total of $20,574 has been awarded under exercised
options within this contract. The most recent development option was completed as of December 31, 2021.

The contracts with NIAID/HHS and BARDA/HHS are cost-plus-fixed-fee contracts. That is, the Company is entitled to receive reimbursement for
all costs incurred in accordance with the contract provisions that are related to the development of galidesivir plus a fixed fee, or profit. BARDA/HHS and
NIAID/HHS will make periodic assessments of progress, and the continuation of the contracts is based on the Company’s performance, the timeliness and
quality of deliverables, and other factors. The government has rights under certain contract clauses to terminate these contracts. These contracts are
terminable by the government at any time for breach or without cause.

U.S. Department of Health and Human Services (“HHS”). In September 2018, HHS awarded the Company a $34,660 contract for the procurement

of up to 50,000 doses of RAPIVAB (peramivir injection) over a five-year period. The Company delivered 20,000 doses of RAPIVAB under this contract in
2019 for a total price of approximately $13.9 million. For the year ended December 31, 2021, the Company delivered a total of 9,980 doses for $6,918. On
September 1, 2021, the Company announced that HHS exercised its option to purchase an additional 10,000 doses of RAPIVAB under this contract for a
total price of approximately $6.9 million which has not been delivered as of December 31, 2021. As of December 31, 2021, the Company has delivered a
total of 29,980 RAPIVAB doses of the 50,000 RAPIVAB doses available under the contract with HHS.

Torii Pharmaceutical Co., Ltd. (“Torii”). On November 5, 2019, the Company entered into a Commercialization and License Agreement with Torii
(the “Torii Agreement”), granting Torii the exclusive right to commercialize ORLADEYO for the prevention of hereditary angioedema (“HAE”) attacks in
Japan.

Under the Torii Agreement, the Company received an upfront, non-refundable payment of $22,000. The Japanese National Health Insurance
System’s (“NHI”) approval of the addition of ORLADEYO to the NHI drug price list in April 2021 triggered a $15,000 milestone payment from Torii to
the Company, which was received in May 2021.

In addition, under the Torii Agreement, the Company is entitled to receive tiered royalty payments, ranging from 20% to 40% of annual net sales of
ORLADEYO in Japan during each calendar year. Torii’s royalty payment obligations are subject to customary reductions in certain circumstances, but may
not be reduced by more than 50% of the amount that otherwise would have been payable to the Company in the applicable calendar quarter. Torii’s royalty
payment obligations commenced upon the first commercial sale of ORLADEYO in Japan and expire upon the later of (i) the tenth anniversary of the date
of first commercial sale of ORLADEYO in Japan, (ii) the expiration of the Company’s patents covering ORLADEYO, and (iii) the expiration of regulatory
exclusivity for ORLADEYO in Japan. The Company is responsible for supplying Torii with its required amounts of ORLADEYO. The activities of the
parties pursuant to the Torii Agreement are overseen by a joint steering committee, composed of an equal number of representatives from each party to
coordinate the development and commercialization of ORLADEYO in Japan. Torii launched ORLADEYO in Japan on April 23, 2021.

The Company identified performance obligations related to (i) the license to develop and commercialize ORLADEYO, (ii) regulatory approval
support and (iii) reimbursement pricing approval support. These were each determined to be distinct from the other performance obligations. The Company
allocated the $22,000 upfront consideration to the identified performance obligations using estimation approaches to determine the standalone selling prices
under ASC Topic 606. Specifically, in determining the value related to the license, a valuation approach utilizing risk adjusted discounted cash flow
projections was used, and an expected cost plus margin approach was utilized for the other performance obligations. For the year ended December 31,
2020, $1,899 of the $22,000 upfront payment was recognized as revenue as the services were delivered. Prior to 2020, the Company had recognized as
revenue $20,101 of the $22,000 upfront payment.

Seqirus UK Limited (“SUL”). On June 16, 2015, the Company and SUL, a limited company organized under the laws of the United Kingdom and a
subsidiary of CSL Limited, a company organized under the laws of Australia, entered into a License Agreement (the “SUL Agreement”) granting SUL and
its affiliates worldwide rights to develop, manufacture and commercialize RAPIVAB (peramivir injection) for the treatment of influenza except for the
rights to conduct such activities in Israel, Japan, Korea and Taiwan (the permitted geographies together constituting the “Territory”). Under the terms of the
SUL Agreement, the Company received an upfront payment of $33,740 and has achieved all development milestones under the contract totaling $12,000.

On March 4, 2020, the International Court of Arbitration of the International Chamber of Commerce (“ICC Tribunal”) delivered a Partial Arbitration

Award (the “Partial Arbitration Award”) in an arbitration matter between the Company and SUL with respect to the SUL Agreement. In the Partial
Arbitration Award, the ICC Tribunal found that, during the term, SUL materially breached and abandoned its core duties to the Company under the Diligent
Efforts (as defined in the SUL Agreement) requirements of the SUL Agreement as applicable in the U.S. The ICC Tribunal granted a declaratory judgment
in favor of the Company terminating the SUL Agreement and restoring all rights to peramivir to the Company. The parties agreed on a transition process
for the product, with a full transition of commercialization of the product in the U.S. and Australia returned to the Company as of August 1, 2020 and
November 1, 2020, respectively. The ICC Tribunal also awarded the Company its attorneys’ fees and expenses incurred in securing the declaratory
judgment as well as the costs incurred by the Company in the arbitration. Finally, the ICC Tribunal found that SUL breached the SUL Agreement by failing
to pay the milestone payment due to the Company within 30 days of the approval of peramivir for adult use in the European Union and awarded the
Company $5,000 (plus interest) for this claim. The ICC Tribunal retained jurisdiction for further proceedings relating to the award of attorneys’ fees and for
any dispute relating to the return to the Company of all rights to peramivir in the Territory. The Company recognized a settlement gain of $8,893 in other
income and legal fees and other expenses of $5,026 in selling, general and administrative expenses for the year ended December 31, 2020.

81

 
 
 
 
 
 
 
 
 
 
Shionogi & Co., Ltd. (“Shionogi”). In February 2007, the Company entered into an exclusive license agreement with Shionogi to develop and
commercialize peramivir in Japan for the treatment of seasonal and potentially life-threatening human influenza. Under the terms of the agreement,
Shionogi obtained rights to injectable formulations of peramivir in Japan. The Company developed peramivir under a license from UAB and will owe
sublicense payments to UAB on any future milestone payments and/or royalties received by the Company from Shionogi. In October 2008, the Company
and Shionogi amended the license agreement to expand the territory covered by the agreement to include Taiwan. Shionogi has commercially launched
peramivir under the commercial name RAPIACTA in Japan and Taiwan.

Green Cross Corporation (“Green Cross”). In June 2006, the Company entered into an agreement with Green Cross to develop and commercialize
peramivir in Korea. Under the terms of the agreement, Green Cross is responsible for all development, regulatory, and commercialization costs in Korea
and the Company is entitled to share in profits resulting from the sale of peramivir in Korea, including the sale of peramivir to the Korean government for
stockpiling purposes. Furthermore, Green Cross will pay the Company a premium over its cost to supply peramivir for development and any future
marketing of peramivir products in Korea.

Albert Einstein College of Medicine of Yeshiva University and Industrial Research, Ltd. (“AECOM” and “IRL,” respectively). In June 2000, the

Company licensed a series of potent inhibitors of PNP from AECOM and IRL, (together, the “Licensors”). The lead product candidate from this
collaboration is forodesine. The Company has obtained worldwide exclusive rights to develop and ultimately distribute this, or any other, product
candidates that might arise from research on these inhibitors. The Company has the option to expand the agreement to include other inventions in the field
made by the investigators or employees of the Licensors. Under this agreement, as amended and restated, the Company has agreed to use commercially
reasonable efforts to develop these drugs and to pay certain milestone payments for each licensed product (which range in the aggregate from $1,400 to
almost $4,000 per indication) for future development, single digit royalties on net sales of any resulting product made by the Company, and to share a
portion of future payments received from other third-party partners, if any. In addition, the Company has agreed to pay annual license fees, which can range
from $150 to $500, that are creditable against actual royalties and other payments due to the Licensors. The Licensors have also granted the Company an
exclusive worldwide license of galidesivir for any antiviral use.

The University of Alabama at Birmingham (“UAB”). The Company currently has agreements with UAB for influenza neuraminidase and
complement inhibitors. Under the terms of these agreements, UAB performed specific research for the Company in return for research payments and
license fees. UAB has granted the Company certain rights to any discoveries in these areas resulting from research developed by UAB or jointly developed
by UAB with the Company. The Company has agreed to pay single digit royalties on sales of any resulting product and to share in future payments
received from other third-party partners. The Company has completed the research under the UAB agreements. These two agreements each have an initial
25-year term, are automatically renewable for five-year terms throughout the life of the last patent and are terminable by the Company upon three months’
notice and by UAB under certain circumstances. Upon termination, both parties shall cease using the other parties’ proprietary and confidential information
and materials, the parties shall jointly own joint inventions and UAB shall resume full ownership of all UAB licensed products. There is currently no
activity between the Company and UAB on these agreements, but when the Company licenses this technology, such as in the case of the Shionogi and
Green Cross collaborations, or commercializes products related to these programs, the Company will owe sublicense fees or royalties on amounts received.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of BioCryst Pharmaceuticals, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of BioCryst Pharmaceuticals, Inc. (the Company) as of December 31, 2021 and 2020, the
related consolidated statements of comprehensive income, shareholders’ 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 Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or
required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2)
involved our especially challenging, subjective or complex judgments. The communication of critical audit matters 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 matters below, providing separate opinions
on the critical audit matters or on the accounts or disclosures to which they relate.

Description of the
Matter

Accrued Clinical Trial and Manufacturing Activities

As discussed in Note 1 to the consolidated financial statements, the Company has recorded $72.7 million of
accrued  expenses  which  includes  costs  for  clinical  trial  and  manufacturing  activities  (together,  clinical
related activities) based upon estimates of expenses incurred through the balance sheet date that have yet to
be  invoiced  by  the  contract  research  organizations  (CROs),  clinical  study  sites,  contract  manufacturing
organizations,  or  other  vendors  (together,  clinical  vendors).  This  accrual  process  involves  identifying
services  that  have  been  performed  and  estimating  the  level  of  service  performed  and  the  associated  cost
when the Company has not yet been invoiced or otherwise notified of actual cost.

Auditing the Company’s accruals for costs associated with in-process clinical related activities may include
judgment  because  the  timing  and  pattern  of  vendor  invoicing  may  not  correspond  to  the  level  of  services
provided and the estimate can incorporate significant assumptions such as expected patient enrollment, site
activation, and estimated project duration.

How We Addressed
the Matter in Our
Audit

We  obtained  an  understanding,  evaluated  the  design  and  tested  the  operating  effectiveness  of  internal
controls that addressed the information used in and the identified risks related to the Company’s process for
recording accrued costs for clinical related activities.

To  evaluate  the  accrual  for  clinical  related  expenses,  our  audit  procedures  included,  among  others,
inspecting  the  Company’s  contracts  with  clinical  vendors  (including  pending  change  orders),  testing  the
completeness  and  accuracy  of  the  underlying  data  used  in  the  estimate  of  the  level  of  service  provided
including evaluating the significant assumptions as discussed above for the applicable in process contracts
with clinical vendors. To assess the significant assumptions, we corroborated the progress of clinical related
activities  through  inquiry  with  the  Company’s  clinical  team  and  with  information  obtained  directly  from
third  party  clinical  vendors,  as  well  as  tested  invoices  received  from  clinical  vendors  subsequent  to  the
balance sheet date.

Description of the
Matter

Royalty Financing Obligations

As described in Note 8 to the consolidated financial statements, the Company entered into Royalty Purchase
Agreements  (“RPA’s”)  with  third  parties.  Pursuant  to  the  RPA’s,  the  Company  received  proceeds  of
approximately  $425  million  in  exchange  for  the  right  to  receive  royalty  payments  based  on  future  net
revenues of the Company’s drug, Orladeyo, and the drug candidates within the BCRX 9930 program.

The Company recorded the RPA’s as non-current liability instruments (royalty financing obligations) on the
balance  sheet  at  their  carrying  value  of  $449.4  million  as  of  December  31,  2021  and  imputed  interest
expense associated with these liabilities using the effective interest rate method. The effective interest rate is
calculated based on the rate that would enable the liability to be repaid in full over the anticipated life of the
arrangement. The interest rate on this liability may vary during the term of the agreement depending on a
number  of  factors,  including  the  level  and  timing  of  forecasted  net  revenues  which  affects  the  repayment
timing  and  ultimate  amount  of  repayment.  In  order  to  amortize  the  royalty  financing  obligations,  the
Company utilizes the prospective method to estimate the future royalties to be paid by the Company to the
third parties over the life of the arrangements. Under the prospective method, a new effective interest rate is
determined based on the revised estimate of remaining cash flows. The Company periodically assesses the
amount and timing of expected royalty payments using a combination of internal projections and forecasts
from external sources.

Auditing  the  royalty  financing  obligations  was  complex  and  highly  judgmental  due  to  the  estimation
uncertainty in determining the effective interest rate. The Company’s effective interest rate models includes
actual revenues recorded and royalties paid to-date, as well as revenue projections for which future royalties
will be paid, which are sensitive to significant assumptions (including population, penetration, probability of
success, and sales price, among others) that are affected by expectations about future market conditions.

How We Addressed
the Matter in Our
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over
the  Company’s  processes  to  account  for  the  royalty  financing  obligations,  including  controls  over
management’s review of the revenue projections within the models.

Description of the
Matter

To  evaluate  the  royalty  financing  obligations,  our  audit  procedures  included,  among  others,  assessing  the
underlying data and assumptions used by the Company in its effective interest rate models. We compared the
significant  assumptions  in  the  revenue  projections  to  current  industry,  market  and  economic  trends.  We
recalculated the current year interest expense based on the amortization schedules and estimates of royalties
using  the  effective  interest  method,  and  performed  sensitivity  analyses  to  evaluate  the  changes  in  the
effective interest rates, and associated interest expense, that would result from changes in the assumptions.

Product Sales, net

As discussed in Note 1, when recognizing revenue, the Company makes an estimate of the net selling price
(transaction  price),  which  includes  estimates  of  variable  consideration.  For  the  year  ended  December  31,
2021,  the  Company  recorded  net  product  sales  of  $136.4  million.  Product  sales  are  recorded  net  of
adjustments  for  variable  consideration  including  estimated  government  rebates,  managed  care  rebates,
chargebacks,  costs  of  co-payment  for  assistance  programs,  and  product  returns  at  the  time  revenue  is
recorded.  Limited  historical  data  is  available  for  use  in  developing  such  estimates  which  are  periodically
reviewed and adjusted as necessary.

Auditing  the  Company’s  net  product  sales  was  complex  due  to  the  Company’s  limited  history  of  product
sales.  The  Company’s  estimates  of  variable  consideration  depend  on  the  identification  of  key  customer
contract  terms  and  conditions,  as  well  as  estimates  of  sales  volumes  to  different  classes  of  payors.  The
revenue recognition process can be complex and can involve judgment related to these estimates as well as
to identify and assess the terms and conditions of customer agreements and related government regulations
that  could  affect  revenue  recognition,  as  the  Company’s  revenue  expands  with  new  customers  and  new
markets.

84

 
 
 
 
 
 
 
 
 
 
 
 
 
 
How We Addressed
the Matter in Our
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over
the  Company’s  process  of  recording  product  sales  and  related  rebates,  chargebacks  and  returns.  We  also
tested  management’s  controls  related  to  the  identification  and  assessment  of  the  terms  and  conditions  of
customer agreements and the completeness and accuracy of data utilized in the controls, and the calculations
supporting management’s estimates.

To test product sales, our audit procedures included, among others, tracing a sample of revenue transactions
recognized during the year to source documentation. We also confirmed a sample of outstanding receivable
balances directly with the Company’s customers. To test management’s estimates of variable consideration,
we  obtained  management’s  calculations  for  the  respective  estimates  and  performed  one  or  more  of  the
following  procedures:  tested  management’s  estimation  process  to  assess  whether  the  recorded  reserve
balances  are  within  a  reasonable  range  of  estimate,  performed  retrospective  reviews,  assessed  subsequent
events, and tested a sample of credits issued throughout the year.

We have served as the Company’s auditor since 1993.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of BioCryst Pharmaceuticals, Inc.

Opinion on Internal Control Over Financial Reporting

We have audited BioCryst Pharmaceuticals 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, BioCryst Pharmaceuticals Inc. (the Company) maintained, in all material respects, effective internal control over financial
reporting as of December 31, 2021, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated
balance sheets of BioCryst Pharmaceuticals, Inc. as of December 31, 2021 and 2020, the related consolidated statements of comprehensive income,
shareholders’ 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.

ITEM 9A.         CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain a set of disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports that

we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported, within
the time periods specified in the SEC’s rules and forms. Our disclosure controls and procedures include, without limitation, controls and procedures
designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and
communicated to management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding
required disclosure. We carried out an evaluation as required by paragraph (b) of Rule 13a-15 or Rule 15d-15 under the Exchange Act, under the
supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design
and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Exchange Act). Based on that
evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2021, our disclosure controls and procedures are
effective.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the
effectiveness of internal control over financial reporting. As defined in Rule 13a-15(f) or Rule 15d-15(f) under the Exchange Act, internal control over
financial reporting is a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our Board
of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the
financial statements in accordance with U.S. GAAP. Internal control over financial reporting includes policies and procedures that (1) pertain to the
maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and the dispositions of our assets; (2) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that our receipts and
expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our 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.

In connection with the preparation of our annual financial statements, management has undertaken an assessment of the effectiveness of our 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 Framework). Management’s assessment included an
evaluation of the design of our internal control over financial reporting and testing of the operational effectiveness of those controls.

Based on this assessment, management has concluded that, as of December 31, 2021, our internal control over financial reporting was effective.

Management believes our internal control over financial reporting will provide reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in accordance with U.S. GAAP.

Ernst & Young LLP, the independent registered public accounting firm that audited our financial statements included in this report, has issued an

attestation report on the Company’s internal control over financial reporting, a copy of which appears on page 86 of this annual report.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2021 that have

materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

RESTRICTED STOCK UNIT AGREEMENT

WITNESSETH:

RECITALS

A.    The Board of Directors (the “Board”) of BioCryst Pharmaceuticals, Inc. (the “Company”) has adopted the Company’s Stock Incentive Plan
(the “Plan”) for the purpose of attracting and retaining the services of its employees (including officers and directors), non-employee Board members and
consultants and other independent contractors who contribute to the financial success of the Company or its parent or subsidiary corporations.

B.    Recipient is an individual who has rendered and is to render valuable services to the Company or its parent or subsidiary corporations, and

this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection with the Company’s grant of the Restricted
Stock Unit Award to Recipient.

NOW, THEREFORE, it is hereby agreed as follows:

The terms and conditions of the Award of restricted stock units with respect to Common Stock of the Company (the “RSUs”) made to the

Recipient, as set forth in the accompanying Notice of Restricted Stock Unit Award (the “Award Notice”), are as follows:

1.

Issuance of RSUs.

(a)    The RSUs are hereby granted and issued to the Recipient, effective as of the Grant Date set forth in the accompanying Award

Notice, in consideration of the employment services rendered and to be rendered by the Recipient to the Company in accordance with Article Three of the
Plan. Each RSU represents the right to receive one share of Common Stock, subject to the terms and conditions hereof. This Award is made subject to and
awarded upon the terms and conditions set forth in this Agreement and the Plan.

(b)    As promptly as practicable following the vesting of the RSUs pursuant to Section 2 (and in all events no later than March 15 of the

year following the year of vesting (unless earlier delivery is required by Section 409A of the Code or delivery is deferred pursuant to a nonqualified
deferred compensation plan in accordance with the requirements of Section 409A of the Code)), the Company shall issue, in the name of the Recipient, the
number of shares of Common Stock that have vested.

(c)    The Recipient agrees that the RSUs shall be subject to the forfeiture provisions set forth in Section 3 of this Agreement and the

restrictions on transfer set forth in Section 4 of this Agreement.

2. General Vesting Terms; Lapsing of Restrictions.

(a)    Vesting Schedule. Subject to Recipient’s continuous employment with or service to the Company from the Grant Date through each

applicable Vesting Date, the RSUs shall vest and no longer be subject to forfeiture with respect to __________ (___%) of the RSUs on
__________________ (each such ________ a “Vesting Date”).

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(b)    Change in Control. If a Change in Control occurs, Article III, Section 2 of the Plan shall govern the treatment of the RSUs in

connection therewith.

(c)    Continuous Employment and Service. For purposes of this Agreement, Recipient shall be deemed to remain in continuous service

with the Company for so long as the Recipient continues to render periodic services to the Company or any parent or subsidiary corporation, whether as an
employee, a non-employee member of the Company’s Board of Directors or an independent consultant or advisor. The Recipient shall be deemed to be an
“employee” for so long as Recipient remains in the employ of the Company or one or more of its parent or subsidiary corporations subject to the control
and direction of the employer entity as to both the work to be performed and the manner and method of performance. For purposes of this Agreement, a
corporation shall be considered to be a subsidiary corporation of the Company if it is a member of an unbroken chain of corporations beginning with the
Company, provided each such corporation in the chain (other than the last corporation) owns, at the time of determination, stock possessing 50% or more of
the total combined voting power of all classes of stock in one of the other corporations in such chain. Similarly, for purposes of this Agreement, a
corporation shall be considered to be a parent corporation of the Company if it is a member of an unbroken chain ending with the Company, provided each
such corporation in the chain (other than the Company) owns, at the time of determination, stock possessing 50% or more of the total combined voting
power of all classes of stock in one of the other corporations in such chain.

3. Forfeiture of Unvested RSUs Upon Employment Termination.

In the event that the Recipient ceases to be continuously employed by or continuously in service to the Company or one or more of its parent or

subsidiary corporations for any reason or no reason, with or without cause, except as otherwise expressly provided in Section 2 above, all of the RSUs that
are unvested as of the time of such employment termination shall be forfeited immediately and automatically to the Company and no shares of Common
Stock shall be issued with respect thereto, without the payment of any consideration to the Recipient, effective as of such termination of employment or
separation from service. The Recipient shall have no further rights with respect to any RSUs that are so forfeited. If the Recipient is employed by a
subsidiary of the Company, any references in this Agreement to employment with the Company shall instead be deemed to refer to employment with such
subsidiary.

4. Restrictions on Transfer.

The Recipient shall not sell, assign, transfer, pledge, hypothecate or otherwise dispose of, by operation of law or otherwise (collectively “transfer”)
any RSUs, or any interest therein (but may transfer Common Stock after its issuance pursuant to Section 1(b) above). Notwithstanding the foregoing to the
extent permitted by applicable law, the RSUs may be assigned in whole or part during the Recipient’s lifetime pursuant to a domestic relations
order; provided, however, that such RSUs shall in all cases remain subject to this Agreement (including, without limitation, the forfeiture provisions set
forth in Section 3 and the restrictions on transfer set forth in this Section 4) and such permitted transferee shall, as a condition to such transfer, deliver to the
Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of this Agreement. The Company shall not
be required: (i) to transfer on its books any of the RSUs (or issue shares of Common Stock with respect thereto) which have been transferred in violation of
any of the provisions of this Agreement or (ii) to treat as owner of such RSUs any transferee to whom such RSUs have been transferred in violation of any
of the provisions of this Agreement.

 
 
 
 
 
 
 
 
 
 
 
5. Rights as a Shareholder.

The Recipient shall have no rights as a shareholder with respect to the RSUs until such times as shares of Common Stock are issued in settlement

thereof; provided, however, that if any dividends and distributions with respect to the shares of Common Stock underlying the RSUs are paid in cash or
shares, or consist of a dividend or distribution to holders of Common Stock other than an ordinary cash dividend, the shares, cash or other property will be
credited to a notional account on behalf of the Recipient subject to the same restrictions on transferability and forfeitability as the related RSUs.

6. Tax Matters.

(a)    Acknowledgments. The Recipient acknowledges that Recipient is responsible for obtaining the advice of the Recipient’s own tax

advisors with respect to the acquisition and vesting of the RSUs and that Recipient is relying solely on such advisors and not on any statements or
representations of the Company or any of its agents with respect to the tax consequences relating to the RSUs. The Recipient understands that the Recipient
(and not the Company) shall be responsible for any and all of Recipient’s tax liabilities that may arise in connection with the acquisition, vesting and/or
settlement of the RSUs.

(b)    Withholding. Unless the Plan Administrator expressly authorizes otherwise, the Recipient shall satisfy all tax withholding

obligations arising in connection with the vesting of RSUs by either (i) automatically having withheld or otherwise transferring to the Company, effective
as of each Vesting Date, such number of shares of Common Stock underlying the RSUs that vest on such Vesting Date as have a fair market value
(calculated in accordance with the Plan) equal to the amount of the applicable tax withholding obligations in connection with the vesting and settlement of
such RSUs, or (ii) through a sale-to-cover transaction authorized by the Recipient, pursuant to which an immediate open-market sale of a portion of the
shares of Common Stock issued to Recipient will be effected, for and on behalf of the Recipient, by the Company’s designated broker to cover such
withholding obligations (however, no sale-to-cover transaction shall be effected unless such a sale is at the time permissible under the Company’s insider
trading policies governing the sale of Common Stock). The Recipient further acknowledges and agrees that the Company has the right to deduct from
payments of any kind otherwise due to the Recipient any other federal, state, local or other taxes of any kind required by law to be withheld with respect to
the vesting and settlement of the RSUs in the event the withholding of shares of Common Stock authorized above is insufficient to satisfy all tax
withholding obligations. If requested by the Plan Administrator, the Recipient agrees to satisfy such tax withholding obligations by making a cash payment
to the Company on the date of vesting of the RSUs, in such amount as the Company determines is necessary to satisfy its withholding obligations in
connection with the vesting and settlement of such RSUs.

7. Miscellaneous.

(a)    Authority of the Plan Administrator. In making any decisions or taking any actions with respect to the matters covered by this

Agreement, the Plan Administrator shall have full authority and discretion, and shall be subject to all of the protections provided for in the Plan. All
decisions and actions by the Plan Administrator with respect to this Agreement shall be made in the Plan Administrator’s sole discretion and shall be final
and binding on all.

(b)    No Employment or Service Contract. The Recipient acknowledges and agrees that, notwithstanding the fact that vesting and

settlement of the RSUs is contingent upon Recipient’s continued employment with, or service to, the Company (or any parent or subsidiary corporation of
the Company employing or retaining Recipient), this Agreement does not constitute an express or implied promise of continued employment or service and
nothing herein or in the Plan shall confer upon the Recipient any rights to continue in the employment or service of the Company (or any parent or
subsidiary corporation of the Company employing or retaining Recipient) for any period of time or interfere with or otherwise restrict in any way the rights
of the Company (or any parent or subsidiary corporation of the Company employing or retaining Recipient) or Recipient, which rights are hereby expressly
reserved by each, to terminate Recipient’s service or employment at any time for any reason whatsoever, with or without cause.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
(c)    Notices. Any notice required to be given or delivered to the Company under the terms of this Agreement shall be in writing and
addressed to the Company in care of the Corporate Secretary at its principal corporate offices. Any notice required to be given or delivered to Recipient
shall be in writing and addressed to the Recipient at the address indicated below Recipient’s signature line of the Award Notice or such address as Recipient
may provide for the Company to keep on file as updated from time to time. All notices shall be deemed to have been given or delivered upon personal
delivery or upon deposit in the U. S. Mail, postage prepaid and properly addressed to the party to be notified.

(d)    Construction; Amendment. The Recipient acknowledges that Recipient has read this Agreement, has received and read the Plan, and

understands the terms and conditions of this Agreement and the Plan. This Agreement and the RSUs evidenced hereby are made and granted pursuant to
the Plan and are in all respects limited by and subject to the express terms and provisions of the Plan. All decisions of the Plan Administrator with respect
to any question or issue arising under the Plan or this Agreement shall be conclusive and binding on all persons having or claiming an interest in the RSUs.
This Agreement may only be amended by a writing executed by the parties hereto expressly providing for amendment of this Agreement except that the
Plan Administrator may unilaterally make amendments that do not adversely affect Recipient’s rights hereunder, provided timely notice of such
amendments is provided to Recipient.

(e)    Successors and Assigns. Except to the extent otherwise expressly provided herein, the provisions of this Agreement shall inure to
the benefit of, and be binding upon, the successors, administrators, heirs, legal representatives and assigns of Recipient and the successors and assigns of
the Company.

(f)    Liability of the Company. If the RSUs exceed, as of the Grant Date, the number of shares of Common Stock which may without

shareholder approval be issued under the Plan, then this Award shall be void with respect to such excess shares unless shareholder approval of an
amendment sufficiently increasing the number of shares of Common Stock issuable under the Plan is obtained in accordance with the provisions of this
Plan and all applicable laws. The inability of the Company to obtain approval from any regulatory body having authority deemed by the Company to be
necessary to the lawful issuance and sale of any Common Stock pursuant to this Agreement shall relieve the Company of any liability with respect to the
non-issuance or sale of the Common Stock as to which such approval shall not have been obtained. The Company, however, shall use its best efforts to
obtain all such approvals.

(g)    Compliance with Laws and Regulations. The award of RSUs hereunder and the settlement thereof is subject to compliance by the
Company and Recipient with all applicable requirements of law relating thereto and all applicable regulations of any stock exchange or over-the-counter
market on which such shares may be listed or traded at the time of such exercise and issuance. In connection with the settlement of RSUs, Recipient shall
execute and deliver to the Company such representations in writing as may be requested by the Company in order for it to comply with the applicable
requirements of federal and state securities laws.

 
 
 
 
 
 
 
 
(h)    Capitalized Terms/Conflict. Capitalized terms not specifically defined herein have the meaning specified in the Plan. In the event of

a conflict between the terms and conditions of this Agreement and the Plan, the Plan controls.

(i)    Electronic Delivery. Recipient hereby consents to the delivery of information (including, without limitation, information required to

be delivered to Recipient pursuant to applicable securities laws) regarding the Company and its subsidiaries and affiliates, the Plan, and the RSUs via
Company web site or other electronic delivery.

Lenders to exercise all rights and remedies available to them under Section 9.02 of the Credit Agreement. Each reference in the Credit Agreement

be  made  pursuant  to  this  Section  2.03(b)  (such  declined  amounts,  the  “Declined  Proceeds”)  by  providing  written  notice  (each,  a
“Rejection Notice”)  to  the  Administrative  Agent  no  later  than  3:00  p.m.  two  (2)  Business  Days  prior  to  the  date  of  such  prepayment.
Each Rejection Notice from a given Lender shall specify the principal amount of the mandatory repayment of Loans to be rejected by
such Lender. If a Lender fails to deliver a Rejection Notice to the Administrative Agent within the time frame specified above or such
Rejection Notice fails to specify the principal amount of the Loans to be rejected, any such failure will be deemed an acceptance of the
total  amount  of  such  mandatory  prepayment  of  Loans.  Any  Declined  Proceeds  shall  be  offered  to  the  Lenders  not  so  declining  such
prepayment on a pro rata basis in accordance with the amounts of the Loans of such Lender (with such non-declining Lenders having the
right to decline any prepayment with Declined Proceeds by providing written notice to the Administrative Agent no later than 3:00 p.m.
one (1) Business Day prior to the date of such prepayment). If a non-declining Lender fails to deliver notice to the Administrative Agent
within the time frame specified, any such non-declining Lender shall be deemed to have declined the additional proceeds. To the extent
such non-declining Lenders elect to decline their share of such Declined Proceeds, any Declined Proceeds remaining thereafter shall be
retained by the Borrower.

(vi)        Repatriation.  Notwithstanding  the  foregoing  terms  of  this  Section  2.03(b),  to  the  extent  any  or  all  of  the  Net  Cash
Proceeds  of  any  Disposition  by,  or  receipt  of  the  Net  Cash  Proceeds  of  any  Involuntary  Disposition  or  Extraordinary  Receipts  by,  a
Subsidiary  that  is  a  Non-U.S.  Subsidiary  otherwise  giving  rise  to  a  prepayment  pursuant  to  this  Section 2.03(b),  is  prohibited  by  any
applicable  local  requirements  of  Law  from  being  repatriated  to  the  Borrower  or  any  Subsidiary  that  is  a  U.S.  Subsidiary  including
through the repayment of intercompany Indebtedness (each, a “Repatriation”; with “Repatriated” having a correlative meaning), provided
that  the  Borrower  and  its  Subsidiaries  shall  take  all  commercially  reasonable  actions  available  under  local  Law  to  permit  such
Repatriation, or if the Repatriation of any such amount would reasonably be expected to result in material adverse tax consequences with
respect  to  the  Borrower  and  its  Subsidiaries,  taken  as  a  whole,  an  amount  equal  to  the  portion  of  such  Net  Cash  Proceeds  so  affected
(such amount, the “Excluded  Prepayment  Amount”),  will  not  be  required  to  be  applied  to  prepay  Loans  at  the  times  provided  in  this
Section 2.03(b); provided, that if and to the extent any such Repatriation ceases to be prohibited, restricted or delayed by applicable local
requirements  of  Law  or  such  Repatriation  ceases,  to  result  in  material  adverse  tax  consequences  with  respect  to  the  Borrower  and  its
Subsidiaries,  taken  as  a  whole  (taking  into  account  any  foreign  tax  credit  or  benefit  actually  received  in  connection  with  such
Repatriation),  at  any  time  following  the  date  on  which  the  applicable  mandatory  prepayment  pursuant  to  this  Section  2.03(b)  was
otherwise required to be made, the Borrower shall promptly pay an amount equal to such portion of the Excluded Prepayment Amount to
the Lenders, which payment shall be applied in accordance with Section 2.03(b)(iv). Notwithstanding anything to the contrary contained
herein or in any other Loan Document, for the avoidance of doubt, nothing in this Section 2.03(b) shall require the Borrower to cause any
amounts to be repatriated to the United States.

52

 
 
 
 
(c)    Change of Control. Upon the occurrence of a Change of Control, the Borrower shall, unless otherwise directed by the Required
Lenders, on the date of the occurrence of such Change of Control (i) prepay the Outstanding Amount of the Loans together with all accrued and unpaid
interest thereon plus the prepayment or repayment premium, if any, required by Section 2.03(d), and the exit fee required under Section 2.07(b) plus all
other Obligations, (ii) in the event such Change of Control occurs (or a definitive agreement in respect of such Change of Control is entered into)
during the Term Loan B Availability Period, pay to the Lenders an amount equal to [***] and (iii) in the event such Change of Control occurs (or
a definitive agreement in respect of such Change of Control is entered into) during the Term Loan C Availability Period, pay to the Lenders an

the Administrative Agent or any other Secured Party has as a result of an Event of Default arising from the occurrence of such Change of Control).

if all or any portion of the Loans are repaid, prepaid, or required to be repaid or prepaid (including by acceleration, including automatic acceleration
triggered  by  any  insolvency  proceeding  pursuant  to  Section  9.01(f)),  pursuant  to  this  Section 2.03, Article  IX  or  otherwise,  then,  in  all  cases,  the
Borrower shall pay to the Lenders, for their respective ratable accounts, on the date on which such repayment or prepayment is paid or required to be paid,
in addition to the other Obligations so repaid, prepaid or required to be repaid or prepaid, a prepayment or repayment premium equal to: (i) with respect to
any prepayment or repayment paid or required to be paid on or prior to the second anniversary of the date of the Borrowing of such Loan, an amount
equal to the Make-Whole Amount with respect to such prepayment or repayment, (ii) with respect to any prepayment or repayment paid or required to be
paid after the second anniversary of the date of the Borrowing of such Loan, but on or prior to the third anniversary of the date of the Borrowing of such
Loan,  two  percent  (2.00%)  of  the  principal  amount  of  such  Loan  that  is  prepaid  or  required  to  be  prepaid,  (iii)  with  respect  to  any  prepayment  or
repayment paid or required to be paid after the third anniversary of the date of the Borrowing of such Loan, but on or prior to the fourth anniversary of the
date of the Borrowing of such Loan, one percent (1.00%) of the principal amount of such Loan that is prepaid or required to be prepaid and (iv) with
respect to any prepayment or repayment paid or required to be paid after the fourth anniversary of the date of the Borrowing of such Loan, zero percent
(0.00%) of the principal amount of such Loan that is prepaid or required to be prepaid.

(e)         Failure to Draw.

to [***].

(ii)         (x) If the Term C Borrowing has not occurred during the Term C Availability Period and (y) [***], the Borrower shall,
unless otherwise directed by the Required Lenders, pay to the Lenders on the last date of the Term C Availability Period an amount equal

53

 
 
 
 
 
 
 
2.04    Termination of Commitments.

(a)    Voluntary. The Borrower may, upon written notice to the Administrative Agent during (i) the Term B Availability Period, terminate
in full the Term B Commitments or (ii) the Term C Availability Period, terminate in full the Term C Commitments; provided, that: (x) any such notice
shall be received by the Administrative Agent not later than 9:00 a.m. five (5) Business Days prior to the date of termination and (y) the Borrower
shall,  unless  otherwise  directed  by  the  Required  Lenders,  on  the  date  of  such  termination  (1)  in  connection  with  a  termination  of  the  Term  B
Commitments, pay to the Lenders an amount equal to [***] and (2) in connection with a termination of the Term C Commitments, pay to the
Lenders an amount equal to [***]. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable. Upon any termination of the
Term  B  Commitments  or  the  Term  C  Commitments,  the  Commitments  of  each  Appropriate  Lender  shall  be  reduced  by  such  Lender’s  Applicable
Percentage of such reduction amount. The Borrower may not terminate the Term A Commitments.

(b)        Mandatory.  The  Term  A  Commitments  will  be  automatically  and  permanently  reduced  to  zero  upon  the  Term  A  Borrowing
pursuant  to  Section 2.01.  The  Term  B  Commitments  will  be  automatically  and  permanently  reduced  to  zero  upon  the  Term  B  Borrowing  pursuant  to
Section 2.01. The Term C Commitments will be automatically and permanently reduced to zero upon the Term C Borrowing pursuant to Section 2.01. The
Term A Commitments shall be automatically and permanently reduced to zero on the date that the Term A Availability Period shall end. The Term B
Commitments  shall  be  automatically  and  permanently  reduced  to  zero  on  the  date  that  the  Term  B  Availability  Period  shall  end.  The  Term  C
Commitments shall be automatically and permanently reduced to zero on the date that the Term C Availability Period shall end.

Notwithstanding anything to the contrary in this Agreement or any other Loan Document, if all or any portion of the Commitments are
terminated pursuant to Article IX, then the Borrower shall pay to the Lenders, for their respective ratable accounts, on the date on which such
termination occurs (1) in connection with a termination of the Term B Commitments, pay to the Lenders an amount equal to the Make-Whole
Amount plus the commitment fee required under Section 2.07(a) plus the exit fee required under Section 2.07(b), which amount shall be calculated
as  if  the  Term  B  Loan  Borrowing  had  occurred  and  the  full  amount  (which  amount  shall  be  $[***])  of  the  Term  B  Loan  had  been  drawn  and
repaid  in  full,  in  each  case,  on  the  date  of  such  termination  and  (2)  in  connection  with  a  termination  of  the  Term  C  Commitments,  pay  to  the
Lenders an amount equal to the Make-Whole Amount plus the commitment fee required under Section 2.07(a) plus the exit fee required under
Section  2.07(b)  which  amount  shall  be  calculated  as  if  the  Term  C  Loan  Borrowing  had  occurred  and  the  full  amount  (which  amount  shall  be
$[***]) of the Term C Loan had been drawn and repaid in full, in each case, on the date of such termination.

For the avoidance of doubt, in the event the Borrower (i) voluntarily prepays all outstanding Loans pursuant to Section 2.03(a) or (ii) is
required to prepay all outstanding Loans pursuant to Section 2.03(b), any of the Term B Commitments and Term C Commitments that are then in
effect shall automatically terminate in full upon any such prepayment and the amounts set forth in clauses (y)(1) and (2) of Section 2.04(a) shall be
immediately due and payable to the Lenders.

54

 
 
 
 
 
 
 
2.05    Repayment of Loans.

The Borrower shall repay the outstanding principal amount of the Loans, together with all accrued and unpaid interest thereon, the prepayment
and repayment premiums required by Section 2.03(d) (provided, for clarity, that such premiums under Section 2.03(d) shall not be due and payable as a
result of a repayment made pursuant to this Section 2.05 due to the occurrence of the date set forth in clause (a) of the definition of “Maturity Date”), the
exit fee required under Section 2.07(b) and all other outstanding Obligations, on the Maturity Date. Loans repaid or prepaid may not be reborrowed.

2.06    Interest; Other Amounts.

(a)    Pre-Default Rate. Subject to the provisions of subsection (b) below, during any Interest Period each Loan shall bear interest during
such Interest Period on the outstanding principal amount thereof either, (i) if such Interest Period (A) ends on or before the last day of the eighth (8th) full
fiscal quarter ending after the Term A Borrowing Date and a Cash Pay Election is made pursuant to Section 2.06(d) for such Interest Period or (B) begins
after the last day of the eighth (8th) full fiscal quarter ending after the Term A Borrowing Date, at a rate equal to the sum of (x) Three-Month LIBOR for
such Interest Period plus (y) 8.25% per annum, or (ii) if such Interest Period ends on or before the last day of the eighth (8th) full fiscal quarter ending
after the Term A Borrowing Date and a PIK Election is made pursuant to Section 2.06(d) for such Interest Period, at a rate equal to the sum of (x) Three-
Month LIBOR for such Interest Period plus (y) 10.25%, per annum.

(b)        Default  Rate.  Notwithstanding  anything  the  contrary  set  forth  in  Section  2.06(a),  (i)  upon  the  occurrence  of  and  during  the
continuance of any Event of Default during any Interest Period all outstanding Obligations shall bear interest during the continuance of such Event of
Default at an interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws and (ii) accrued and unpaid
interest  (including  interest  on  past  due  interest)  shall  be  due  and  payable  in  cash  on  demand.  The  interest  rate  shall  be  recalculated  and,  if  necessary,
adjusted for each Interest Period, in each case pursuant to the terms hereof.

(c)    Interest Generally. Subject to Section 2.06(b), interest on each Loan shall be due and payable in cash in arrears on each Interest
Payment Date unless a PIK Election is made pursuant to Section 2.06(d) and at such other times as may be specified herein. Interest hereunder shall be
due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any
Debtor Relief Law.

(d)    PIK Interest Election. For each Interest Period ending on or before the last day of the eighth (8th) full fiscal quarter ending after the
Term A Borrowing Date, the Borrower hereby elects (such election, a “PIK Election”) that, so long as (x) no Default or Event of Default has occurred and
is continuing and (y) the Borrower has not, at least five (5) Business Days prior to the beginning of such Interest Period, provided the Administrative
Agent a written election indicating that it will decline the PIK Election for such Interest Period and interest on any Loan accrued during such Interest
Period shall be due and payable in cash in arrears on the applicable Interest Payment Date (a “Cash Pay Election”), interest on any Loan accrued during
such Interest Period may be paid in kind (“PIK Interest”) by capitalizing the entire amount of such PIK Interest with the unpaid principal amount of such
Loan outstanding on the last day of such Interest Period (each, a “PIK Interest Payment”). Following each such increase in the principal amount of such
Loan as a result of any PIK Interest Payment, such Loans will bear interest on such increased principal amount from and after the date of each such PIK
Interest Payment and each reference to such Loan shall include such PIK Interest for all purposes of the Loan Documents.

2.07    Fees.

(a)    Commitment Fee. The Borrower shall pay to the Lenders, for their respective ratable accounts, on the date of each Borrowing (or a
deemed Borrowing pursuant to Section 2.03 or Section 2.04), a commitment fee in an amount equal to one percent (1.00%) of the principal amount of
the  Loans  borrowed  (or  deemed  borrowed)  on  such  date.  Such  fee  shall  be  fully  earned  when  paid  and  shall  be  non-refundable  for  any  reason
whatsoever. It is understood and agreed that Athyrium, the Administrative Agent and the Lenders reserve the right to allocate, in whole or in part, to their
respective Affiliates, the fees payable to such Persons hereunder in such manner as Athyrium, the Administrative Agent, the Lenders and such Affiliates
shall agree in their sole discretion.

(b)    Exit Fee. If all or any portion of the Loans are repaid, prepaid, or required to be repaid or prepaid (including by acceleration) or
deemed repaid or prepaid, pursuant to Section 2.03, Section 2.04, Section 2.05, Article IX or otherwise, then, in all cases, the Borrower shall pay to the
Lenders, for their respective ratable accounts, on the date on which such repayment or prepayment is repaid, paid or, required to be repaid or prepaid or
deemed  repaid  or  prepaid,  as  the  case  may  be,  in  addition  to  the  other  Obligations  so  prepaid,  repaid or, required  to  be  prepaid  or  repaid  or  deemed
repaid or prepaid, an exit fee in an amount equal to two percent (2.00%) of the principal amount of such Loan prepaid, repaid or, required to be prepaid
or repaid or deemed repaid or prepaid, as the case may be, on such date.

2.08    Evidence of Debt.

The  Loans  made  by  each  Lender  shall  be  evidenced  by  one  or  more  accounts  or  records  maintained  by  such  Lender  in  the  ordinary  course  of
business. The accounts or records maintained by each Lender shall be conclusive absent manifest error of the amount of Loans made by the Lenders to the
Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation
of the Borrower hereunder to pay any amount owing with respect to the Obligations. Upon the request of any Lender made through the Administrative
Agent, the Borrower shall execute and deliver to such Lender a promissory note, which shall evidence such Lender’s Loans in addition to such accounts or
records. Each such promissory note shall (a) in the case of the Term A Loans, be in the form of Exhibit B-1 (a “Term A Note”), (b) in the case of the Term
B Loans, be in the form of Exhibit B-2 (a “Term B Note”) and (c) in the case of the Term C Loans, be in the form of Exhibit B-3 (the “Term C Note”). Each
Lender may attach schedules to its Note and endorse thereon the date, amount and maturity of its Loans and payments with respect thereto.

2.09    Computation of Interest.

All computations of interest shall be made on the basis of a 360-day year and actual days elapsed. Interest shall accrue on each Loan for the day on

which such Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which such Loan or such portion is paid.

2.10    Payments Generally.

56

 
 
 
 
 
 
 
 
 
 
(a)    General. All payments to be made by the Borrower shall be made free and clear of and without condition or deduction (subject to
Section 3.01) for any counterclaim, defense, recoupment or setoff. Subject to Section 9.03, all payments of principal, interest, prepayment and repayment
premiums and fees on the Loans and all other Obligations payable by any Loan Party under the Loan Documents shall be due, without any presentment
thereof,  directly  to  the  Lenders,  at  the  respective  Lending  Offices  of  the  Lenders;  provided,  that,  if  at  the  time  of  any  such  payment  a  Lender  is  a
Defaulting Lender, such Defaulting Lender’s pro rata share of such payment shall be made directly to the Administrative Agent. The Loan Parties will
make such payments in Dollars, in immediately available funds not later than 2:00 p.m. on the date due, marked for attention as indicated, or in such other
manner or to such other account in any United States bank as the Lenders may from time to time direct in writing. All payments received by the Lenders
after 2:00 p.m. shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue in respect of such
succeeding Business Day. If any payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall be made on the
next following Business Day, and such extension of time shall be reflected in computing interest.

(b)    Obligations of Lenders are Several. The obligations of the Lenders hereunder to make Loans and to make payments pursuant to
Section 12.04(d)  are  several  and  not  joint.  The  failure  of  any  Lender  to  make  any  Loan  or  to  make  any  payment  under  Section 12.04(d)  on  any  date
required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the
failure of any other Lender to so make its Loan or to make its payment under Section 12.04(d).

(c)    Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain the funds to make any Loan in any particular
place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds to make any Loan in any particular place or
manner.

2.11    Sharing of Payments by Lenders.

If any Lender shall, by exercising any right of setoff or otherwise, obtain payment in respect of any principal of or interest on its portion of any of
the Loans or prepayment or repayment premium or exit fees in connection therewith resulting in such Lender’s receiving payment of a proportion of the
aggregate amount of the Loans and accrued interest thereon and prepayment or repayment premium or exit fees in connection therewith greater than its pro
rata share  thereof  as  provided  herein,  then  such  Lender  shall  (a)  notify  the  Administrative  Agent  of  such  fact  and  (b)  purchase  for  cash  at  face  value
participations  in  the  portions  of  the  Loans  of  the  Other  Lenders,  or  make  such  other  adjustments  as  shall  be  equitable,  so  that  the  benefit  of  all  such
payments  shall  be  shared  by  the  Lenders  ratably  in  accordance  with  the  aggregate  amount  of  principal  of,  accrued  interest  on  and  prepayment  and
repayment premiums or exit fees in connection with their respective portions of the Loans and other amounts owing them; provided, that:

(i)    if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations

shall be rescinded and the purchase price shall be restored to the extent of such recovery, without interest; and

(ii)        the  provisions  of  this  Section 2.11  shall  not  be  construed  to  apply  to  (x)  any  payment  made  by  or  on  behalf  of  the  Borrower
pursuant  to  and  in  accordance  with  the  express  terms  of  this  Agreement  (including  the  application  of  funds  arising  from  the  existence  of  a
Defaulting  Lender)  or  (y)  any  payment  obtained  by  a  Lender  as  consideration  for  the  assignment  of  or  sale  of  any  participation  in  any  of  its
portion of the Loans to any assignee or participant, other than an assignment to the Borrower or any Subsidiary (as to which the provisions of this
Section shall apply).

57

 
 
 
 
 
 
 
 
 
Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Lender acquiring a
participation  pursuant  to  the  foregoing  arrangements  may  exercise  against  such  Loan  Party  rights  of  setoff  and  counterclaim  with  respect  to  such
participation as fully as if such Lender were a direct creditor of such Loan Party in the amount of such participation.

2.12    Defaulting Lenders.

then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable Law:

(a)    Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender,

(i)    Waivers and Amendment. The Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect

to this Agreement shall be restricted as set forth in Section 12.01.

(ii)    Reallocation of Payments. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the
account of that Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article IX or otherwise, and including any amounts
made available to the Administrative Agent by that Defaulting Lender pursuant to Section 12.08), shall be applied at such time or times as may
be  determined  by  the  Administrative  Agent  as  follows:  first,  to  the  payment  of  any  amounts  owing  by  that  Defaulting  Lender  to  the
Administrative Agent hereunder; second, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any
Loan  in  respect  of  which  that  Defaulting  Lender  has  failed  to  fund  its  portion  thereof  as  required  by  this  Agreement,  as  determined  by  the
Administrative Agent; third, if so determined by the Administrative Agent and the Borrower, to be held in a non-interest bearing deposit account
and released in order to satisfy obligations of that Defaulting Lender to fund Loans under this Agreement; fourth, to the payment of any amounts
owing to the Lenders as a result of any judgment of a court of competent jurisdiction obtained by any Lender against that Defaulting Lender as a
result of that Defaulting Lender’s breach of its obligations under this Agreement; fifth, so long as no Default or Event of Default exists, to the
payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against
that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; and sixth, to that Defaulting Lender
or as otherwise directed by a court of competent jurisdiction; provided, that, if (x) such payment is a payment of the principal amount of any
Loans in respect of which that Defaulting Lender has not fully funded its appropriate share and (y) such Loans were made at a time when the
conditions set forth in Section 5.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of all non-Defaulting Lenders
on a pro rata basis prior to being applied to the payment of any Loans of that Defaulting Lender. Any payments, prepayments, repayments or
other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender pursuant to this
Section 2.12 (a)(ii) shall be deemed paid to and redirected by that Defaulting Lender, and each Lender irrevocably consents hereto.

(b)    Defaulting Lender Cure. If the Borrower and the Administrative Agent agree in writing in their sole discretion that a Defaulting
Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective
date  specified  in  such  notice  and  subject  to  any  conditions  set  forth  therein,  that  Lender  will  cease  to  be  a  Defaulting  Lender;  provided,  that,  no
adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting
Lender; provided, further, that, except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to
Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender having been a Defaulting Lender.

ARTICLE III

TAXES

3.01    Taxes.

(a)    All payments of principal and interest on the Loans and all other amounts payable hereunder by a Loan Party to any Recipient shall
be made free and clear of and without deduction or withholding for or on account of any present or future income, excise, stamp, documentary, property
or franchise taxes and other taxes, fees, duties, levies, assessments, withholding taxes or other charges of any nature whatsoever (including interest and
penalties thereon), in each case, imposed by any taxing authority (“Taxes”), unless required by applicable Law. If any withholding or deduction of any
Taxes from any payment by or on account of any obligation of any Loan Party hereunder is required by applicable Law (any such Taxes, excluding (w)
Taxes  imposed  on  or  measured  by  net  income,  branch  profits  taxes  and  franchise  taxes,  in  each  case  imposed  by  the  jurisdiction  (or  any  political
subdivision thereof) under or in which a Recipient is organized, has its principal office or applicable lending office or otherwise conducts business or with
which a Recipient has a present or former connection (other than solely as the result of entering into any of the Loan Documents or taking any action
thereunder), (x) U.S. back-up withholding and other withholding Taxes imposed on amounts payable to or for the account of a Recipient with respect to
an applicable interest in any Loan or Commitment pursuant to a Law in effect on the date on which such Recipient acquires such interest in the Loans or
Commitment, except in each case to the extent that, pursuant to this Section 3.01, amounts with respect to such taxes were payable by such Recipient’s
assignor  immediately  before  such  Recipient  became  a  party  hereto,  (y)  Taxes  that  would  not  have  been  imposed  but  for  the  failure  of  a  Recipient  to
provide the Borrower with any certification, form or other documentation (including without limitation an IRS Form W-9 or IRS Form W-8) establishing
an exemption from such Taxes and (z) any withholding tax imposed under FATCA (all non-excluded items shall hereinafter be referred to as “Indemnified
Taxes”, and Taxes described in clauses (w)-(z) shall hereinafter be referred to as “Excluded Taxes”), then (i) the applicable Withholding Agent shall be
entitled to make such withholding or deduction and shall pay directly to the relevant Governmental Authority the full amount required to be so withheld
or deducted within the time allowed and in the minimum amount required by applicable law, (ii) the applicable Withholding Agent shall promptly forward
to  the  Administrative  Agent  an  official  receipt  or  other  documentation  satisfactory  to  the  Administrative  Agent  evidencing  such  payment  to  such
Governmental Authority and (iii) the sum payable by the applicable Loan Party shall be increased by such additional amount or amounts as is necessary to
ensure  that  the  net  amount  actually  received  by  the  applicable  Recipient  will  equal  the  full  amount  such  Recipient  would  have  received  had  no  such
withholding or deduction for Indemnified Taxes been required.

(b)    The Borrower shall indemnify each Recipient, within ten (10) days after demand therefor, for the full amount of any Indemnified
Taxes (including Indemnified Taxes imposed on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be
withheld or deducted from a payment by such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such taxes
were correctly or legally imposed or asserted by the relevant Governmental Authority.

59

 
 
 
 
 
 
(c)    Each Lender shall execute and deliver to the Borrower on or prior to the date that such Lender becomes a party hereto (and from
time to time thereafter upon the reasonable request of the Borrower), one or more (as the Borrower may reasonably request) duly completed and executed
copies of any forms, certificates or documents reasonably requested by the Borrower certifying as to such Lender’s entitlement to any available exemption
from  or  reduction  of  withholding  or  deduction  of  taxes.  In  addition,  any  Lender,  if  reasonably  requested  by  the  Borrower,  shall  deliver  such  other
documentation  prescribed  by  applicable  law  or  reasonably  requested  by  the  Borrower  as  will  enable  the  Borrower  or  the  Administrative  Agent  to
determine whether or not such Lender is subject to backup withholding or information reporting requirements. No Loan Party shall be required to pay
additional  amounts  to  any  Lender  pursuant  to  this  Section  3.01  with  respect  to  taxes  attributable  to  the  failure  of  such  Lender  to  comply  with  this
paragraph.

(d)        Each  Lender  agrees  that  if  any  form  or  certification  it  previously  delivered  pursuant  to  this  Section 3.01  expires  or  becomes
obsolete or inaccurate in any respect, it shall promptly update such form or certification or promptly notify the Administrative Agent and the Borrower of
its inability to do so.

(e)    Each of the parties to the Agreement shall, within ten (10) days of a reasonable request by another party to the Agreement, supply

to that other party

(i)    such forms, documentation and other information relating to its status under FATCA as that other party reasonably requests for the

purposes of that other Party’s compliance with FATCA, and

(ii)    such forms, documentation and other information relating to its status as that other Party reasonably requests for the purposes of

that other Party’s compliance with any other law, regulation, or exchange of information regime, such as the Common Reporting Standard.

(f)    If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has
been indemnified pursuant to this Section (including by the payment of additional amounts pursuant to this Section), it shall pay to the indemnifying party
an  amount  equal  to  such  refund  (but  only  to  the  extent  of  indemnity  payments  made  under  this  Section  with  respect  to  the  Taxes  giving  rise  to  such
refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant
Governmental  Authority  with  respect  to  such  refund).  Such  indemnifying  party,  upon  the  request  of  such  indemnified  party,  shall  repay  to  such
indemnified party the amount paid over pursuant to this clause (f) (plus any penalties, interest or other charges imposed by the relevant Governmental
Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the
contrary in this clause (f), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this clause (f) the
payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax
subject  to  indemnification  and  giving  rise  to  such  refund  had  not  been  deducted,  withheld  or  otherwise  imposed  and  the  indemnification  payments  or
additional amounts with respect to such Tax had never been paid. This clause (f) shall not be construed to require any indemnified party to make available
its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

60

 
 
 
 
 
 
 
 
(g)    If, due to a change in Sections 871(h) or 881(c) of the Internal Revenue Code (or any successor provisions) after the date a Person
becomes an Indirect Lender under this Agreement, any withholding is required to be made by a Lender or any Affiliate thereof to such Indirect Lender
attributable to payments made by any Loan Party hereunder, such Loan Party shall pay to such Lender such additional amount or amounts as is necessary
to ensure that the net amount actually received by any Indirect Lender will equal the full amount such Indirect Lender would have received had no such
withholding or deduction been required; provided that in the event additional amounts are due in respect of an Indirect Lender, immediately before such
Indirect Lender transfers a direct or indirect interest in a Lender to a transferee and withholding is required to be made by a Lender or any Affiliate to such
transferee Indirect Lender attributable to payments made by any Loan Party hereunder, a Loan Party shall be required to pay additional amounts pursuant
to this Section in an amount not exceeding the additional amounts payable prior to the transfer by the transferor Indirect Lender; provided, further that no
such additional amounts shall be payable by a Loan Party to the extent such withholding could have been avoided by any Indirect Lender and each entity
in the chain of ownership between such Indirect Lender and the Lender providing Internal Revenue Service Forms W-9, W-8ECI, W-8BEN, W-8BEN-E
or W-8IMY (as applicable) or any successor forms thereto, to the Lender or other entity in the chain of ownership between such Indirect Lender and the
Lender, as applicable.

3.02    Survival.

All of the Loan Parties’ obligations under this Article III shall survive termination of the Commitments, prepayment or repayment of all

Obligations hereunder and the resignation or replacement of the Administrative Agent.

ARTICLE IV

GUARANTY

4.01    The Guaranty.

Each of the Guarantors hereby jointly and severally guarantees to each Secured Party and the Administrative Agent as hereinafter provided, as
primary obligor and not as surety, the prompt payment of the Obligations of the Borrower and any other Guarantors in full when due (whether at stated
maturity, as a mandatory prepayment, by acceleration or otherwise) strictly in accordance with the terms thereof. The Guarantors hereby further agree that
if  any  of  the  Obligations  are  not  paid  in  full  when  due  (whether  at  stated  maturity,  as  a  mandatory  prepayment,  by  acceleration  or  otherwise),  the
Guarantors will, jointly and severally, promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of
payment or renewal of any of the Obligations, the same will be promptly paid in full when due (whether at extended maturity, as a mandatory prepayment,
by acceleration or otherwise) in accordance with the terms of such extension or renewal.

Notwithstanding any provision to the contrary contained herein or in any other of the Loan Documents, the obligations of each Guarantor under
this Agreement and the other Loan Documents shall be limited to an aggregate amount equal to the largest amount that would not render such obligations
subject to avoidance under the Debtor Relief Laws or any comparable provisions of any applicable state or federal law.

61

 
 
 
 
 
 
 
 
 
4.02    Obligations Unconditional.

The  obligations  of  the  Guarantors  under  Section 4.01  are  joint  and  several,  absolute  and  unconditional,  irrespective  of  the  value,  genuineness,
validity, regularity or enforceability of any of the Loan Documents, or any other agreement or instrument referred to therein, or any substitution, release,
impairment or exchange of any other guarantee of or security for any of the Obligations, and, to the fullest extent permitted by applicable law, irrespective
of  any  law  or  regulation  or  other  circumstance  whatsoever  which  might  otherwise  constitute  a  legal  or  equitable  discharge  or  defense  of  a  surety  or
guarantor, it being the intent of this Section 4.02 that the obligations of the Guarantors hereunder shall be absolute and unconditional under any and all
circumstances.  Each  Guarantor  agrees  that  such  Guarantor  shall  have  no  right  of  subrogation,  indemnity,  reimbursement  or  contribution  against  the
Borrower  or  any  other  Guarantor  for  amounts  paid  under  this  Article  IV  until  such  time  as  the  Obligations  (other  than  contingent  indemnification
obligations for which no claim has been asserted) have been paid in full and the Commitments have expired or terminated. Without limiting the generality
of the foregoing, it is agreed that, to the fullest extent permitted by law, the occurrence of any one or more of the following shall not alter or impair the
liability of any Guarantor hereunder, which shall remain absolute and unconditional as described above:

Obligations shall be extended, or such performance or compliance shall be waived;

(a)    at any time or from time to time, without notice to any Guarantor, the time for any performance of or compliance with any of the

in the Loan Documents shall be done or omitted;

(b)    any of the acts mentioned in any of the provisions of any of the Loan Documents, or any other agreement or instrument referred to

(c)    the maturity of any of the Obligations shall be accelerated, or any of the Obligations shall be modified, supplemented or amended
in any respect, or any right under any of the Loan Documents including any change in the purpose of, an extension of or increase in any facility or the
addition of any new facility under the Loan Documents or other document, or any other agreement or instrument referred to in the Loan Documents shall
be  waived  or  any  other  guarantee  of  any  of  the  Obligations  or  any  security  therefor  shall  be  released,  impaired  or  exchanged  in  whole  or  in  part  or
otherwise dealt with;

(d)    any Lien granted to, or in favor of, any Secured Party as security for any of the Obligations shall fail to attach or be perfected;

any Guarantor) or shall be subordinated to the claims of any Person (including, without limitation, any creditor of any Guarantor); or

(e)    any of the Obligations shall be determined to be void or voidable (including, without limitation, for the benefit of any creditor of

(f)    any insolvency or similar proceedings.

With  respect  to  its  obligations  hereunder,  each  Guarantor  hereby  expressly  waives  diligence,  presentment,  demand  of  payment,  protest  and  all
notices whatsoever, and any requirement that the Secured Parties exhaust any right, power or remedy or proceed against any Person under any of the Loan
Documents, or any other agreement or instrument referred to in the Loan Documents, or against any other Person under any other guarantee of, or security
for, any of the Obligations.

62

 
 
 
 
 
 
 
 
 
 
 
4.03    Reinstatement.

The obligations of the Guarantors under this Article IV shall be automatically reinstated if and to the extent that for any reason any payment by or
on behalf of any Person in respect of the Obligations is rescinded or must be otherwise restored by any holder of any of the Obligations, whether as a result
of any proceedings in bankruptcy or reorganization or otherwise, and each Guarantor agrees that it will indemnify the Secured Parties on demand for all
reasonable costs and expenses (including, without limitation, the fees, charges and disbursements of counsel) incurred by the Secured Parties in connection
with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a
preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law.

4.04    Certain Additional Waivers.

Each Guarantor agrees that such Guarantor shall have no right of recourse to security for the Obligations, except through the exercise of rights of

subrogation pursuant to Section 4.02 and through the exercise of rights of contribution pursuant to Section 4.06.

4.05    Remedies.

The Guarantors agree that, to the fullest extent permitted by law, as between the Guarantors, on the one hand, and the Secured Parties, on the other
hand, the Obligations may be declared to be forthwith due and payable as provided in Section 9.02 (and shall be deemed to have become automatically due
and  payable  in  the  circumstances  provided  in  said  Section 9.02)  for  purposes  of  Section 4.01  notwithstanding  any  stay,  injunction  or  other  prohibition
preventing such declaration (or preventing the Obligations from becoming automatically due and payable) as against any other Person and that, in the event
of such declaration (or the Obligations being deemed to have become automatically due and payable), the Obligations (whether or not due and payable by
any other Person) shall forthwith become due and payable by the Guarantors for purposes of Section 4.01. The Guarantors acknowledge and agree that
their obligations hereunder are secured in accordance with the terms of the Collateral Documents and that the Secured Parties may exercise their remedies
thereunder in accordance with the terms thereof.

4.06    Rights of Contribution.

The Guarantors agree among themselves that, in connection with payments made hereunder, each Guarantor shall have contribution rights against
the other Guarantors as permitted under applicable law. Such contribution rights shall be subordinate and subject in right of payment to the obligations of
such  Guarantors  under  the  Loan  Documents  and  no  Guarantor  shall  exercise  such  rights  of  contribution  until  all  Obligations  (other  than  contingent
indemnification obligations for which no claim has been asserted) have been paid in full and the Commitments have been terminated.

4.07    Guarantee of Payment; Continuing Guarantee.

The  guarantee  in  this  Article IV  is  a  guaranty  of  payment  and  not  of  collection,  is  a  continuing  guarantee,  and  shall  apply  to  all  Obligations

whenever arising.

63

 
 
 
 
 
 
 
 
 
 
 
 
4.08    Limitations.

The guarantee in this Article IV insofar as it is from BioCryst Ireland Limited does not apply to any liability to the extent that it would result in

such guarantee constituting unlawful financial assistance within the meaning of Section 82 of the Companies Act.

4.09    Guarantor Intent

Without prejudice to generality of Section 4.02, each Guarantor expressly confirms that it intends that this Guaranty shall extend from time to time
to any (however fundamental) variation, increase, extension or addition of or to any of the Loan Documents, Collateral and/or any facility or amount made
available under any of the Loan Documents for the purposes of or in connection with any of the following: business acquisitions of any nature; increasing
working capital; enabling investor distributions to be made; carrying out restructurings; refinancing existing facilities; refinancing any other indebtedness;
making facilities available to new borrowers; any other variation or extension of the purposes for which any such facility or amount might be made
available from time to time; and any fees, costs and/or expenses associated with any of the foregoing.

contested in good faith by appropriate proceedings diligently conducted or (b) the failure to comply therewith could not reasonably be expected to have a
Material Adverse Effect.

6.17    Intellectual Property; Licenses, Etc.

(a)    Schedule 6.17 Part (a) sets forth a complete and accurate list of the following as of the Closing Date: (i) all Copyrights and all
Trademarks of any Loan Party or any Subsidiary, that are registered, or in respect of which an application for registration has been filed or recorded, with
the  United  States  Patent  and  Trademark  Office  or  the  United  States  Copyright  Office  or  with  any  other  Governmental  Authority  (or  comparable
organization  or  office  established  in  any  country  or  pursuant  to  an  international  treaty  or  similar  international  agreement  for  the  filing,  recordation  or
registration of interests in intellectual property), together with relevant identifying information with respect to such Copyrights and Trademarks, (ii) all
Patents of any Loan Party or any Subsidiary that are issued, or in respect of which an application has been filed or recorded, with the United States Patent
and  Trademark  Office  or  with  any  other  Governmental  Authority  (or  comparable  organization  or  office  established  in  any  country  or  pursuant  to  an
international treaty or similar international agreement for the filing, recordation or registration of interests in intellectual property), together with relevant
identifying information with respect to such Patents, (iii) all Domain Names owned by any Loan Party or any Subsidiary or which any Loan Party or any
Subsidiary is licensed, authorized or otherwise granted rights under or to, or owned by a Person on behalf of any Loan Party or any Subsidiary, together
with relevant identifying information with respect to such Domain Names, (iv) each Copyright License, each Patent License and each Trademark License
of any Loan Party or any Subsidiary and (v) each other Material IP Right of any Loan Party or any Subsidiary, in each case with respect to this clause (v),
other than Trade Secrets.

(b)    All Material IP Rights (other than Material IP Rights that are not material or are no longer used or useful in any material respect in
the business of the Borrower or any of its Subsidiaries) are in full force and effect, and have not expired, lapsed or been forfeited, cancelled or abandoned.
Each of the Borrower and the Subsidiaries, have, since taking title to the Material IP Rights, performed all acts and have paid all required annuities, fees,
costs, expenses and taxes to maintain the Material IP Rights in full force and effect in each of the Key Territories, as applicable, or have caused others to
do the same. All documents filed or recorded with a patent office or other relevant intellectual property registry for registration, recordation or issuance of
Material IP Rights in each of the Key Territories have been duly and properly filed and recorded. None of the Material IP Rights have been or are subject
to any pending or outstanding injunction, directive, order, judgment, or other disposition of dispute that adversely restricts, or when any such pending
dispute is concluded may adversely restrict, the use, transfer, registration, licensing or other exploitation of any such Material IP Rights in any of the Key
Territories, or otherwise adversely affects, or may adversely affect, the scope, validity, use, right to use, registrability, or enforceability of such Material IP
Rights in any of the Key Territories. No action or proceeding is pending that could reasonably be expected to result in any of the foregoing.

(c)    The Borrower or a Subsidiary owns or has a valid license or other valid right to use all Material IP Rights, free and clear of any and
all Liens other than Permitted Liens. To the extent any of the Material IP Rights were authored, developed, conceived or created, in whole or in part, for or
on behalf of the Borrower or a Subsidiary by any Person, then the Borrower or the Subsidiary or their predecessors in interest, as applicable, has entered
into a written agreement with such Person in which such Person has assigned all right, title and interest in and to such Material IP Rights to the Borrower
or such Subsidiary, or their predecessors in interest, including the right to sue for and collect past damages, as applicable. Except as otherwise indicated on
Schedule 6.17 Part (b), each of the Borrower and each Subsidiary is the sole and exclusive owner of all right, title and interest in and to all such Material
IP Rights that are owned by it.

75

 
 
 
 
 
 
 
(d)    Neither the Borrower nor any Subsidiary has made any assignment or agreement in conflict with the security interest in any of the
Material IP Rights of the Borrower or any Subsidiary hereunder and no license agreement with respect to any of the Material IP Rights conflicts with the
security interest granted to the Administrative Agent, on behalf of the Lenders, pursuant to the terms of the Collateral Documents. Except as described in
Schedule 6.17 Part (c), and except for software that is commercially available to the public, no Loan Party is a party to, nor is bound by, any inbound
license or other similar agreement, the failure, breach or termination of which could reasonably be expected to cause a Material Adverse Effect, or that
prohibits or otherwise restricts the Loan Parties from granting a security interest in the applicable Loan Party’s interest in such license or agreement or any
other property.

(e)    To the Loan Parties’ knowledge, no Person is infringing, misappropriating, violating, or diluting any Material IP Rights (i) as of
the  Closing  Date  and  (ii)  after  the  Closing  Date  in  a  manner  that  could  reasonably  be  expected  to  result  in  a  material  adverse  effect  on  any  Product
Development and Commercialization Activities, and as of the Closing Date, no Loan Party has given notice to any third party alleging that such third
party is infringing, misappropriating, violating, or diluting, any Material IP Rights.

(f)    With respect to each Copyright License, Trademark License and Patent License listed on Schedule 6.17 Part (a)(iv) that comprise
Material  IP  Rights,  such  agreement  (i)  is  in  full  force  and  effect  and  is  binding  upon  and  enforceable  against  the  Borrower  and  the  Subsidiaries  party
thereto and all other parties thereto in accordance with its terms, (ii) has not been amended or otherwise modified and (iii) has not suffered a default or
breach thereunder, in each case of the foregoing clauses (i), (ii) and (iii), (A) as of the Closing Date, and (B) after the Closing Date, except as could not
reasonably  be  expected  to  result  in  a  material  adverse  effect  on  any  Product  Development  and  Commercialization  Activities.  To  the  Loan  Parties’
knowledge, neither the Borrower nor any of the Subsidiaries has taken any action that would permit any other Person party to any such license agreement
to have, and no such Person otherwise has, any defenses, counterclaims or rights of setoff thereunder (1) as of the Closing Date and (2) after the Closing
Date, that could reasonably be expected to result in a material adverse effect on any Product Development and Commercialization Activities.

(g)    Except as set forth on Schedule 6.17 Part (d), (i) no written claim, and no other claim known to the Borrower or any Subsidiary has
been  made  that  alleges  that  the  Material  IP  Rights,  or  the  conduct  or  operation  of  its  business  of  the  Borrower  or  the  Subsidiaries,  including  the
development, manufacture, use, sale, provision or other commercialization of any Product or Service, infringes, misappropriates, violates, or dilutes any
intellectual property or proprietary or other rights of that third party, in each case, (A) as of the Closing Date and (B) after the Closing Date that could be
reasonably expected to result in a material adverse effect on any Product Development and Commercialization Activities and (ii) there is no basis for such
a claim known to the Borrower or any Subsidiary.

(A)    as of the Closing Date the consummation of the transactions contemplated hereby and, except as otherwise permitted by
Section 7.18(b), the exercise by the Administrative Agent or the Lenders of any right or remedy set forth in the Loan Documents will not
constitute a breach or violation of, or otherwise affect the enforceability or approval of, (i) any licenses associated with Material IP Rights
or (ii) any Material Required Permits; and

(B)        at  any  time  after  the  Closing  Date,  except  with  respect  to  Excluded  Property,  the  consummation  of  the  transactions
contemplated hereby and, except as otherwise permitted by Section 7.18(b), the exercise by the Administrative Agent or the Lenders of
any right or remedy set forth in the Loan Documents will not constitute a breach or violation of, or otherwise affect the enforceability or
approval of, (i) any licenses associated with IP Rights or (ii) any Required Permits.

6.18    Solvency.

The Borrower is Solvent on an individual basis, and the Borrower and its Subsidiaries are Solvent on a consolidated basis.

(b) each Guarantor is (i) as set forth on Schedule 6.20(b) or (ii) as set forth on Schedule 1 to the Joinder Agreement pursuant to which such Guarantor
became a party hereto. Except as set forth on Schedule 6.20(c), no Loan Party has during the five years preceding the Closing Date (i) changed its legal
name, (ii) changed its jurisdiction of organization, or (iii) been party to a merger, amalgamation, consolidation or such other structural change.

6.21    Sanctions Concerns; Anti-Corruption Laws; PATRIOT Act.

(a)    Sanctions Concerns. No Loan Party, nor any Subsidiary, nor JPR Royalty Sub, nor, to the knowledge of the Loan Parties and their
Subsidiaries, any director, officer, employee, agent, Affiliate or representative thereof, is an individual or entity that is, or is owned or controlled by, any
individual or entity that is (i) currently the subject or target of any Sanctions, (ii) included on OFAC’s List of Specially Designated Nationals, HMT’s

(b)    Anti-Corruption Laws. The Loan Parties, their Subsidiaries and JPR Royalty Sub have conducted their business in compliance
with the United States Foreign Corrupt Practices Act of 1977, the UK Bribery Act 2010 and other similar anti-corruption legislation in other applicable
jurisdictions, and have instituted and maintained policies and procedures designed to promote and achieve compliance with such Laws.

(c)    PATRIOT Act. To the extent applicable, each of the Loan Parties, their Subsidiaries and JPR Royalty Sub is in compliance, in all
material respects, with (i) the Trading with the Enemy Act, as amended, and each of the foreign assets control regulations of the United States Treasury
Department (31 CFR, Subtitle B, Chapter V, as amended) and any other enabling legislation or executive order relating thereto and (ii) the PATRIOT Act.

6.22    Material Contracts.

Except for the Organization Documents of the Loan Parties and the other agreements set forth on Schedule 6.22 as of the Closing Date there are
no  (a)  employment  agreements  covering  the  management  of  the  Borrower  or  any  Subsidiary,  (b)  collective  bargaining  agreements  or  other  labor
agreements  covering  any  employees  of  the  Borrower  or  any  Subsidiary,  (c)  agreements  for  managerial,  consulting  or  similar  services  to  which  the
Borrower or any Subsidiary is a party or by which it is bound, (d) agreements regarding the Borrower or any Subsidiary, its assets or operations or any
investment therein to which any of its equity holders is a party or by which it is bound, (e) real estate leases, licenses of IP Rights or other lease or license

preceding clauses (a), (c), (d), (e) and (f) solely to the extent the breach, default or the termination of such agreement, lease or license could reasonably be
expected to result in a material adverse effect on Product Development and Commercialization Activities or (g) any other agreements or instruments to
which  the  Borrower  or  any  Subsidiary  is  a  party,  and  the  breach,  nonperformance  or  cancellation  of  which,  or  the  failure  of  which  to  renew,  could
reasonably be expected to have a Material Adverse Effect. Schedule 6.22 sets forth, with respect to each real estate lease agreement to which the Borrower
or any Subsidiary is a party as of the Closing Date, the address of the subject property and the annual rental (or, where applicable, a general description of
the method of computing the annual rental). The consummation of the transactions contemplated by the Loan Documents will not give rise to a right of
termination in favor of any party to any Material Contract. Each Material Contract (a) is in full force and effect and is binding upon and enforceable against
the Borrower and its Subsidiaries party thereto and, to the knowledge of any Loan Party, all other parties thereto in accordance with its terms, and (b) is not
currently subject to any material breach or default by the Borrower or any Subsidiary or, to the knowledge of any Loan Party, any other party thereto. None
of the Borrower nor any of its Subsidiaries has taken or failed to take any action that would permit any other Person party to any Material Contract to have,
and, to the knowledge of any Loan Party, no such Person otherwise has, any defenses, counterclaims or rights of setoff thereunder (1) as of the Closing
Date  and  (2)  after  the  Closing  Date  that  could  reasonably  be  expected  to  result  in  a  material  adverse  effect  on  any  Product  Development  and
Commercialization  Activities.  As  of  the  Closing  Date,  none  of  the  Material  Contracts  are  non-assignable  by  their  terms  (other  than  those  certain
agreements separately noted in Schedule 6.22 as being non-assignable) or as a matter of law, or prevent the granting of a security interest therein.

(b)    The Borrower and its Subsidiaries have not received any written communication from any Governmental Authority regarding, and
there  are  no  facts  or  circumstances  that  are  likely  to  give  rise  to,  (A)  any  material  adverse  change  in  any  Material  Required  Permit,  or  any  failure  to
materially  comply  with  any  Laws  or  any  term  or  requirement  of  any  Material  Required  Permit,  (B)  any  revocation,  withdrawal,  suspension,  hold,

other  Governmental  Authority,  committed  an  act,  made  a  statement,  or  failed  to  make  a  statement,  in  each  case  that  could  reasonably  be  expected  to
provide a basis for the FDA to invoke its policy respecting “Fraud, Untrue Statements of Material Facts, Bribery, and Illegal Gratuities,” set forth in 56
Fed. Reg. 46191 (September 10, 1991) or for any other Government Authority to invoke a similar policy or Law.

and are being conducted in compliance with applicable provisions of cGMP as required by 21 U.S.C. § 351(a)(2)(B) and as set forth in 21 C.F.R. Parts
210  and  211  and  applicable  guidance  documents,  as  amended  from  time  to  time.  Neither  the  Borrower  nor  any  Subsidiary  nor  to  the  Loan  Parties’
knowledge, any third party conducting services on behalf of the Borrower or its Subsidiaries, has received from the FDA a Warning Letter, Form FDA-

(p)    Each of the Facilities is duly registered or licensed under the applicable Laws of the jurisdiction where the Facility is located. The
Facilities and the services provided at such Facilities are qualified for participation in the Government Reimbursement Programs, and each Loan Party and
each of their Subsidiaries is entitled to reimbursement under the Government Reimbursement Programs for services rendered at such Facilities to qualified
beneficiaries. To the knowledge of any Loan Party, all Persons providing professional health care services for or on behalf of any Loan Party (either as an
employee  or  independent  contractor)  are  appropriately  licensed  in  every  jurisdiction  in  which  they  hold  themselves  out  as  professional  health  care
providers.

(q)    Each Loan Party and each of their respective Subsidiaries has received and maintain accreditation in good standing and without
impairment by all applicable Accrediting Organizations, to the extent required by Law (including any equivalent regulation) or the terms of any Operating
Lease pertaining to any Facility. No Loan Party nor any of its respective Subsidiaries has received any notice or communication from any Accrediting
Organization that a Facility is (i) subject to or is required to file a plan of correction with respect to any accreditation survey, or (ii) in danger of losing its
accreditation due to a failure to comply with a plan of correction.

(r)    Any Operating Lease has been approved by all necessary Governmental Authorities. Under applicable Laws in the jurisdiction in
which each Facility is located, the reimbursement rate of the applicable Loan Party under any applicable Governmental Reimbursement Program is not
affected by the rental rates under the Operating Lease. The rentals provided for under the Operating Lease comply with all applicable Laws and do not
exceed the sums permitted to be paid under applicable Laws.

(s)    No Loan Party, nor any of its respective Subsidiaries, nor any of their respective officers, nor, to the knowledge of any Loan Party,
any  of  their  respective  employees,  agents  or  contractors,  have  engaged  in  any  activity  which  is  not  in  compliance  in  all  material  respects  with  any
applicable Healthcare Laws. To the knowledge of each Loan Party and its respective Subsidiary, there are no pending and there have been no threatened
investigations, subpoenas, civil investigative demands, actions, suits or proceedings by any Governmental Authority with respect to any alleged violation
by Loan Party or Subsidiary of any Healthcare Laws, except to the extent that any such investigations, subpoenas, civil investigative demands, actions,
suits  or  proceedings  could  not  reasonably  be  expected,  either  individually  or  in  the  aggregate,  to  have  a  material  adverse  effect  on  any  Product
Development and Commercialization Activities and could not reasonably be expected, either individually or in the aggregate, to have a Material Adverse
Effect.

(t)    Each Loan Party and each of their respective Subsidiaries has timely filed or caused to be timely filed all material cost reports
required by any Government Reimbursement Program to have been filed or made with respect to the operations of the Loan Parties. No Loan Party nor

9.02    Remedies Upon Event of Default.

If  any  Event  of  Default  occurs  and  is  continuing,  the  Administrative  Agent  shall,  at  the  request  of,  or  may,  with  the  consent  of,  the  Required

Lenders may take any or all of the following actions:

terminated;

(a)    declare the commitment of each Lender to make Loans to be terminated, whereupon such commitments and obligations shall be

(b)    declare the unpaid principal amount of all outstanding Loans, all interest accrued and unpaid thereon, prepayment and repayment
premiums thereto (if any), the Make-Whole Amount and exit fees and all other amounts owing or payable hereunder or under any other Loan Document
(including the amounts payable pursuant to Section 2.04(b)) to be immediately due and payable, without presentment, demand, protest or other notice
of any kind, all of which are hereby expressly waived by the Loan Parties; and

112

 
 
 
 
 
 
 
 
 
 
 
the Loan Documents;

(c)    exercise on behalf of itself and the Lenders all rights and remedies available to the Administrative Agent and/or the Lenders under

provided, however, that upon the occurrence of an Event of Default under Section 9.01(f) or (g), the obligation of each Lender to make any Loans and
each of the Commitments shall automatically terminate, the unpaid principal amount of all outstanding Loans and all interest, prepayment and repayment
premiums,  including  the  Make-Whole  Amount,  exit  fees  and  other  amounts  as  aforesaid  shall  automatically  become  due  and  payable,  in  each  case
without further act of the Administrative Agent or any Lender.

Upon the Loans becoming due and payable under this Section 9.02, whether by declaration or acceleration (including automatic acceleration
triggered  by  any  insolvency  proceeding  pursuant  to  Section  9.01(f)),  all  outstanding  NotesLoans,  accrued  and  unpaid  interest,  the  prepayment  and
repayment premiums required by Section 2.03(d), including the Make-Whole Amount, the exit fee required by Section 2.07(b) and the other Obligations
(including the amounts payable pursuant to Section 2.04(b), including the Make-Whole Amount) shall become immediately due and payable. If the
Obligations are accelerated for any reason (including automatic acceleration triggered by any insolvency proceeding pursuant to Section 9.01(f)), the
prepayment and repayment premiums required by Section 2.03(d), including the Make-Whole Amount, and the exit fee required by Section 2.07(b) and
the amounts payable pursuant to Section 2.04(b), including the Make-Whole Amount will also be due and payable as though such Obligations were
voluntarily drawn and/or prepaid and any discount on the Loans shall be deemed earned in full and, in each case, shall constitute part of the Obligations,
in view of the impracticability and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation
of each Lender’s lost profits as a result thereof. Any prepayment or repayment premium required by Section 2.03(d), including the Make-Whole Amount,
or  the  exit  fee  required  by  Section  2.07(b)  and  the  amounts  payable  pursuant  to  Section  2.04(b),  including  the  Make-Whole  Amount,  payable
pursuant to the preceding sentence shall be presumed to be the liquidated damages sustained by each Lender as the result of the early termination and the
Loan Parties agree that it is reasonable under the circumstances currently existing. The prepayment and repayment premiums required by Section 2.03(d),
including the Make-Whole Amount, and the exit fee required by Section 2.07(b) and the amounts payable pursuant to Section 2.04(b), including the
Make-Whole Amount, shall also be payable, and any discount on the Loans shall be deemed earned in full, in each case, in the event that the Obligations
(and/or  this  Agreement)  are  satisfied  or  released  by  foreclosure  (whether  by  power  of  judicial  proceeding),  deed  in  lieu  of  foreclosure  or  by  any  other
means. TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE BORROWER AND THE OTHER LOAN PARTIES EXPRESSLY WAIVE THE
PROVISIONS  OF  ANY  PRESENT  OR  FUTURE  STATUTE  OR  LAW  THAT  PROHIBITS  OR  MAY  PROHIBIT  THE  COLLECTION  OF  THE
FOREGOING  PREPAYMENT  OR  REPAYMENT  PREMIUM,  INCLUDING ANY MAKE-WHOLE AMOUNT, EXIT FEE, AMOUNT  AND  ANY
DISCOUNT ON THE LOANS IN CONNECTION WITH ANY SUCH ACCELERATION. The Borrower and the other Loan Parties expressly agree that
(i) the prepayment and repayment premiums required by Section 2.03(d), including the Make-Whole Amount, the exit fee required by Section 2.07(b),
the amounts payable pursuant to Section 2.04(b), including the Make-Whole Amount, and discount on the Loans provided for herein, are reasonable
and are the product of an arm’s length transaction between sophisticated business people, ably represented by counsel, (ii) the prepayment and repayment
premiums required by Section 2.03(d), including the Make-Whole Amount, the exit fee required by Section 2.07(b), the amounts payable pursuant to
Section 2.04(b), including the Make-Whole Amount, and discount on the Loans, shall be payable notwithstanding the then prevailing market rates at the
time  payment  is  made,  (iii)  there  has  been  a  course  of  conduct  between  the  Lenders  and  the  Borrower  and  the  other  Loan  Parties  giving  specific
consideration in this transaction for such agreement to pay the prepayment and repayment premiums required by Section 2.03(d), including the Make-
Whole Amount, the exit fee required by Section 2.07(b), the amounts payable pursuant to Section 2.04(b), including the Make-Whole Amount, and
discount on the Loans, (iv) the Borrower and the other Loan Parties shall be estopped hereafter from claiming differently than as agreed to in this paragraph
and (v) the prepayment premium required by Section 2.03(d), including the Make-Whole Amount, the exit fee required by Section 2.07(b), the amounts
payable pursuant to Section 2.04(b), including the Make-Whole Amount, and any discount on the Loans represent a good faith, reasonable estimate
and  calculation  of  the  lost  profits  or  damages  of  the  Lenders  and  that  it  would  be  impractical  and  extremely  difficult  to  ascertain  the  actual  amount  of
damages to the Lenders or profits lost by the Lenders as a result of any early termination. The Borrower and the other Loan Parties expressly acknowledge
that their agreement to pay the prepayment and repayment premiums required by Section 2.03(d) and, including the Make-Whole Amount, the exit fee
required  by  Section  2.07(b)  and  the  amounts  payable  pursuant  to  Section  2.04(b),  including  the  Make-Whole  Amount,  as  herein  described  and
discount on the Loans to the Lenders as herein described, is a material inducement to the Lenders to make the Loans hereunder. The Loan Parties further
acknowledge  that  each  lender  has  a  right  to  maintain  its  investment  in  the  Loans  free  from  repayment  by  the  Loan  Parties  (except  as  herein
specifically provided for) and that the provision for payment of the prepayment or repayment premium required by Section 2.03(d), including the
Make-Whole Amount, or the exit fee required by Section 2.07(b) and the amounts payable pursuant to Section 2.04(b), including the Make-Whole
Amount, if the Loans are prepaid or accelerated (including automatic acceleration triggered by any insolvency proceeding pursuant to Section
9.01(f)) as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

113

 
 
 
 
 
9.03    Application of Funds.

After the exercise of remedies provided for in Section 9.02 (or after the Loans have automatically become immediately due and payable as set
forth in the proviso to Section 9.02), any amounts received by any Lender or the Administrative Agent on account of the Obligations shall be applied by the
Administrative Agent in the following order:

First, to payment of that portion of the Obligations constituting fees, indemnities, expenses and other amounts (including fees, charges
and disbursements of counsel to the Administrative Agent and amounts payable under Articles III and X) payable to the Administrative Agent in
its capacity as such;

Second,  to  payment  of  that  portion  of  the  Obligations  constituting  fees,  indemnities  and  other  amounts  (other  than  principal,  interest,
prepayment and repayment premiums and exit fees) payable to the Secured Parties (other than the Administrative Agent) (including fees, charges
and  disbursements  of  counsel  to  the  respective  Secured  Parties  (other  than  the  Administrative  Agent))  arising  under  the  Loan  Documents  and
amounts payable under Articles III and X, ratably among them in proportion to the respective amounts described in this clause Second payable to
them;

Third, to payment of that portion of the Obligations constituting accrued and unpaid interest on and prepayment and repayment premiums
and the exit fee with respect to the Loans, ratably among the Lenders in proportion to the respective amounts described in this clause Third held by
them;

114

 
 
 
 
 
 
 
Fourth, to payment of that portion of the Obligations constituting accrued and unpaid principal of the Loans, ratably among the Lenders

in proportion to the respective amounts described in this clause Fourth held by them; and

Last, the balance, if any, after all of the Obligations have been indefeasibly paid in full, to the Borrower or as otherwise required by Law.

9.04    Cure Right. Notwithstanding anything to the contrary contained herein, in the event the Loan Parties fail to comply with the minimum
Orladeyo Consolidated U.S. Net Product Sales requirement set forth in Section 8.17 as of any Test Date, the Borrower shall have a one-time right (the
“Cure Right”), to repay in full the entire amount of the Term C Loans outstanding at such time together with all accrued and unpaid interest thereon plus
the prepayment or repayment premium required by Section 2.03(d) and the exit fee required under Section 2.07(b) plus any other fees or amounts payable
hereunder  at  such  time.  The  exercise  of  the  Cure  Right  shall  be  subject  to  the  following  conditions:  (a)  the  Borrower  shall  have  delivered  to  the
Administrative Agent irrevocable written notice of the Borrower’s intent to exercise the Cure Right with respect to such Test Date not later than 9:00 a.m.
on the date at least five (5) Business Days in advance the Borrower making the Cure Right payment and (b) such Cure Right payment shall be made by the
Borrower no later than thirty (30) days after such Test Date. Following the exercise of the Cure Right and the repayment in full pursuant to this Section
9.04, no Default or Event of Default under Section 9.01(b) for the failure to perform the covenant contained in Section 8.17 shall be deemed to have existed
for so long as, on a pro forma basis, the Loan Parties are in compliance with the financial covenant set forth in Section 8.16(iv).

ARTICLE X

INCREASED COSTS AND INABILITY TO DETERMINE RATES

10.01    Increased Costs, Etc.

(a)    Increased Costs Generally. If any Change in Law shall:

(i)    impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against

assets of, deposits with or for the account of, or credit extended or participated in by, any Lender;

(ii)        subject  any  Recipient  to  any  Taxes  (other  than  (A)  Indemnified  Taxes  and  (B)  Excluded  Taxes)  on  its  loans,  loan  principal,

commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii)    impose on any Lender any other condition, cost or expense (other than Taxes) affecting this Agreement; and the result of any of the
foregoing  shall  be  to  increase  the  cost  to  such  Lender  of  making  or  maintaining  any  Loan  (or  of  maintaining  its  obligation  to  make  any  such
Loan), then, upon written demand of such Lender, the Borrower will pay to such Lender, as the case may be, such additional amount or amounts
as will compensate such Lender, as the case may be, for such additional costs incurred or reduction suffered.

115

 
 
 
 
 
 
 
 
 
 
 
(b)    Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any Lending Office of such
Lender or such Lender’s holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on
such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or
the Loans made by such Lender to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in
Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from
time  to  time  the  Borrower  will  pay  to  such  Lender,  as  the  case  may  be,  such  additional  amount  or  amounts  as  will  compensate  such  Lender  or  such
Lender’s holding company for any such reduction suffered.

(c)        Certificates  for  Reimbursement.  A  certificate  of  a  Lender  setting  forth  the  amount  or  amounts  necessary  to  compensate  such
Lender or its holding company, as the case may be, as specified in clause (a) or (b)  of  this  Section  and  delivered  to  the  Borrower  shall  be  conclusive
absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(d)    Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to the foregoing provisions of this
Section  shall  not  constitute  a  waiver  of  such  Lender’s  right  to  demand  such  compensation,  provided,  that,  the  Borrower  shall  not  be  required  to
compensate  a  Lender  pursuant  to  the  foregoing  provisions  of  this  Section  for  any  increased  costs  incurred  or  reductions  suffered  more  than  nine  (9)
months  prior  to  the  date  that  such  Lender  notifies  the  Borrower  of  the  Change  in  Law  giving  rise  to  such  increased  costs  or  reductions  and  of  such
Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then
the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

10.02    Mitigation Obligations; Replacement of Lenders.

(a)    Designation of a Different Lending Office. If any Lender requests compensation under Section 10.01 or requires the Borrower to
pay  any  Taxes  or  additional  amounts  to  any  Lender  or  any  Governmental  Authority  for  the  account  of  any  Lender  pursuant  to  Section 3.01  or  if  any
Lender gives a notice pursuant to Section 10.04, then at the request of the Borrower such Lender shall, as applicable, use reasonable efforts to designate a
different Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or
affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or
10.01, as the case may be, in the future, or eliminate the need for the notice pursuant to Section 10.04, as applicable, and (ii) in each case, would not
subject such Lender, as the case may be, to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower
hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)    Replacement of Lenders. If any Lender requests compensation under Section 10.01, or if the Borrower is required to pay any Taxes
or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01 and, in each case, such Lender
has  declined  or  is  unable  to  designate  a  different  Lending  Office  in  accordance  with  Section  10.02(a),  the  Borrower  may  replace  such  Lender  in
accordance with Section 12.13.

116

 
 
 
 
 
 
 
 
10.03    Inability to Determine Rates.

(a)    If prior to the commencement of any Interest Period:

(i)         the Administrative Agent determines (which determination shall be conclusive absent manifest error) that (1) adequate

and reasonable means do not exist for ascertaining Three-Month LIBOR for such Interest Period; or

(ii)         the Administrative Agent is advised by the Required Lenders that Three-Month LIBOR for such Interest Period will not

adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by as promptly as practicable thereafter. In the
event of any such determination, until the Administrative Agent has advised the Borrower that the circumstances giving rise to such notice no longer exist,
Three-Month LIBOR shall be determined by the Administrative Agent solely by reference to clause (ii) of the definition of Three-Month LIBOR.

(b)    Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Loan Document, but without limiting
Section 10.03(a) above, upon the occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, the Administrative Agent and
the  Borrower  may  amend  this  Agreement  to  replace  Three-Month  LIBOR  with  a  Benchmark  Replacement.  Any  such  amendment  with  respect  to  a
Benchmark Transition Event will become effective at 5:00 p.m. on the fifth (5th) Business Day after the Administrative Agent has posted such proposed
amendment  to  all  Lenders  and  the  Borrower  so  long  as  the  Administrative  Agent  has  not  received,  by  such  time,  written  notice  of  objection  to  such
amendment from Lenders comprising the Required Lenders. Any such amendment with respect to an Early Opt-in Election will become effective on the
date that Lenders comprising the Required Lenders have delivered to the Administrative Agent written notice that such Required Lenders accept such
amendment. No replacement of Three-Month LIBOR with a Benchmark Replacement pursuant to this Section 10.03 will occur prior to the applicable
Benchmark Transition Start Date.

(c)        Benchmark  Replacement  Conforming  Changes.  In  connection  with  the  implementation  of  a  Benchmark  Replacement,  the
Administrative Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the
contrary  herein  or  in  any  other  Loan  Document,  any  amendments  implementing  such  Benchmark  Replacement  Conforming  Changes  will  become
effective without any further action or consent of any other party to this Agreement.

(d)        Notices:  Standards  for  Decisions  and  Determinations.  The  Administrative  Agent  will  promptly  notify  the  Borrower  and  the
Lenders of (i) any occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date
and  Benchmark  Transition  Start  Date,  (ii)  the  implementation  of  any  Benchmark  Replacement,  (iii)  the  effectiveness  of  any  Benchmark  Replacement
Conforming Changes and (iv) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that
may  be  made  by  the  Administrative  Agent  or  Lenders  pursuant  to  this  Section  10.03,  including  any  determination  with  respect  to  a  tenor,  rate  or
adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action, will be
conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party hereto, except, in
each case, as expressly required pursuant to this Section 10.03.

ARTICLE XI

ADMINISTRATIVE AGENT

11.01    Appointment and Authority.

(a)    Each of the Lenders hereby irrevocably appoints Athyrium Opportunities III Co-Invest 1 LP, a Delaware limited partnership, to act
on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on
its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions, powers and
discretion as are incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent and the Lenders, and neither the
Borrower nor any other Loan Party shall have rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the
term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any
fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law. Instead such term is used as a matter of market
custom, and is intended to create or reflect only an administrative relationship between contracting parties.

(b)       The  Administrative  Agent  shall  also  act  as  the  “collateral  agent”  under  the  Loan  Documents,  and  each  of  the  Lenders  hereby
irrevocably appoints and authorizes the Administrative Agent to act as the agent of such Lender for purposes of acquiring, holding and enforcing any and
all  Liens  on  Collateral  granted  by  any  of  the  Loan  Parties  to  secure  any  of  the  Obligations,  together  with  such  actions,  powers  and  discretion  as  are
incidental thereto. In this connection, the Administrative Agent, as “collateral agent” and any co-agents, sub-agents and attorneys-in-fact appointed by the
Administrative Agent pursuant to Section 11.05 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the
Collateral Documents, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent, shall be entitled to the benefits of
all provisions of this Article XI and Article XII, as though such co-agents, sub-agents and attorneys-in-fact were the “Administrative Agent” under the
Loan Documents as if set forth in full herein with respect thereto. The Administrative Agent is hereby authorized to enter into the Intercreditor Agreement
and any other intercreditor agreement or subordination agreement contemplated by the terms of this Agreement, and each Lender agrees to be bound by
the terms of the Intercreditor Agreement and such other intercreditor agreement or subordination agreement and directs the Administrative Agent to enter
into the Intercreditor Agreement and such other intercreditor agreement or subordination agreement, in each case, on behalf of the Secured Parties and
agrees that the Administrative Agent may take such actions on its behalf as is contemplated by the terms of the Intercreditor Agreement or such other
intercreditor agreement or subordination agreement.

11.02    Rights as a Lender.

The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender
and may exercise the same as though it were not the Administrative Agent, and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated
or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its
Affiliates  may  accept  deposits  from,  lend  money  to,  own  securities  of,  act  as  the  financial  advisor  or  in  any  other  advisory  capacity  for  and  generally
engage  in  any  kind  of  business  with  any  Loan  Party  or  any  Subsidiary  or  other  Affiliate  thereof  as  if  such  Person  were  not  the  Administrative  Agent
hereunder and without any duty to account therefor to the Lenders.

121

 
 
 
 
 
 
 
 
11.03    Exculpatory Provisions.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its

duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent:

(a)    shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(b)        shall  not  have  any  duty  to  take  any  discretionary  action  or  exercise  any  discretionary  powers,  except  discretionary  rights  and
powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the
Required  Lenders  (or  such  other  number  or  percentage  of  the  Lenders  as  shall  be  expressly  provided  for  herein  or  in  the  other  Loan  Documents),
provided,  that,  the  Administrative  Agent  shall  not  be  required  to  take  any  action  that,  in  its  opinion  or  the  opinion  of  its  counsel,  may  expose  the
Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be
in violation of the automatic stay under any Debtor Relief Law or that may affect a forfeiture, modification or termination of property of a Defaulting
Lender in violation of any Debtor Relief Law; and

(c)    shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable
for the failure to disclose, any information relating to any Loan Party or any of its Affiliates that is communicated to or obtained by the Person serving as
the Administrative Agent or any of its Affiliates in any capacity.

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders
(or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary,
under  the  circumstances  as  provided  in  Section  12.01  and  Section  9.02)  or  (ii)  in  the  absence  of  its  own  gross  negligence  or  willful  misconduct  as
determined by a court of competent jurisdiction by final and non-appealable judgment. The Administrative Agent shall be deemed not to have knowledge
of any Default unless and until notice describing such Default is given in writing to the Administrative Agent by the Borrower or a Lender.

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation
made  in  or  in  connection  with  this  Agreement  or  any  other  Loan  Document,  (ii)  the  contents  of  any  certificate,  report  or  other  document  delivered
hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or
conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any
other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article V or elsewhere herein,
other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

11.04    Reliance by Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it
to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement
made  to  it  orally  or  by  telephone  and  believed  by  it  to  have  been  made  by  the  proper  Person,  and  shall  not  incur  any  liability  for  relying  thereon.  In
determining  compliance  with  any  condition  hereunder  to  the  making  of  a  Loan,  that  by  its  terms  must  be  fulfilled  to  the  satisfaction  of  a  Lender,  the
Administrative Agent may presume that such condition is satisfactory to such Lender unless the Administrative Agent shall have received notice to the
contrary from such Lender prior to the making of such Loan. The Administrative Agent may consult with legal counsel (who may be counsel for the Loan
Parties), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the
advice of any such counsel, accountants or experts.

122

 
 
 
 
 
 
 
 
 
 
 
11.05    Delegation of Duties.

The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document
by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and
all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to
any  such  sub-agent  and  to  the  Related  Parties  of  the  Administrative  Agent  and  any  such  sub-agent,  and  shall  apply  to  their  respective  activities  in
connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. The Administrative Agent shall not
be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and non-
appealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents.

11.06    Resignation of Administrative Agent.

The Administrative Agent may resign as Administrative Agent at any time by giving thirty (30) days advance notice thereof to the Lenders and the
Borrower and, thereafter, the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. Upon any such resignation, the
Required  Lenders  shall  have  the  right,  subject  to  the  approval  of  the  Borrower  (so  long  as  no  Event  of  Default  has  occurred  and  is  continuing;  such
approval not to be unreasonably withheld), to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed
by  the  Required  Lenders,  been  approved  (so  long  as  no  Event  of  Default  has  occurred  and  is  continuing)  by  the  Borrower  or  have  accepted  such
appointment within thirty (30) days after the Administrative Agent’s giving of notice of resignation, then the Administrative Agent may, on behalf of the
Lenders, appoint a successor Administrative Agent reasonably acceptable to the Borrower (so long as no Default or Event of Default has occurred and is
continuing).  Upon  the  acceptance  of  any  appointment  as  Administrative  Agent  hereunder  by  a  successor  Administrative  Agent,  such  successor
Administrative  Agent  shall  thereupon  succeed  to  and  become  vested  with  all  rights,  powers,  privileges  and  duties  of  the  retiring  Administrative  Agent.
After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Section 11.06 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it was acting as Administrative Agent. If no successor has accepted appointment as
Administrative Agent by the date which is thirty (30) days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative
Agent’s resignation shall nevertheless thereupon become effective and the Required Lenders shall perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. In the event that a new Administrative Agent is
appointed and such Administrative Agent is not an Affiliate of the holders of a majority in interest of the Loans, then the Borrower shall agree to pay to
such Administrative Agent the fees and expenses (such fees to be payable annually in advance) that such Administrative Agent may reasonably request in
connection with its appointment and service.

123

 
 
 
 
 
 
11.07    Non-Reliance on Administrative Agent and Other Lenders.

Each  Lender  acknowledges  that  it  has,  independently  and  without  reliance  upon  the  Administrative  Agent  or  any  other  Lender  or  any  of  their
Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of
their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in
taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder
or thereunder.

11.08    Administrative Agent May File Proofs of Claim.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as
herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall
be entitled and empowered, by intervention in such proceeding or otherwise:

(a)    to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other
Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and
the  Administrative  Agent  (including  any  claim  for  the  reasonable  compensation,  expenses,  disbursements  and  advances  of  the  Lenders  and  the
Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Section 12.04)
allowed in such judicial proceeding; and

(b)    to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each
Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments
directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the
Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 12.04.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any
Lender  any  plan  of  reorganization,  arrangement,  adjustment  or  composition  affecting  the  Obligations  or  the  rights  of  any  Lender  or  to  authorize  the
Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

11.09    Collateral and Guaranty Matters.

124

 
 
 
 
 
 
 
 
 
 
 
The Lenders irrevocably authorize the Administrative Agent, at its option and in its discretion,

(a)    to release any Lien on any Collateral granted to or held by the Administrative Agent under any Loan Document (i) upon payment
in  full  of  all  Obligations  (other  than  contingent  indemnification  obligations  for  which  no  claim  has  been  asserted)  under  the  Loan  Documents  and  the
termination of all unused Commitments, (ii) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with
any sale or other Disposition permitted hereunder or any Involuntary Disposition, or (iii) as approved in accordance with Section 12.01;

any Lien on such property that is permitted by Section 8.01(i); and

(b)    to subordinate any Lien on any property granted to or held by the Administrative Agent under any Loan Document to the holder of

(c)        to  release  any  Guarantor  from  its  obligations  under  the  Guaranty  (i)  if  such  Person  ceases  to  be  a  Subsidiary  as  a  result  of  a
transaction  permitted  under  the  Loan  Documents  or  (ii)  upon  payment  in  full  of  all  Obligations  (other  than  contingent  indemnification  obligations  for
which no claim has been asserted) under the Loan Documents and the termination of all unused Commitments.

Upon  request  by  the  Administrative  Agent  at  any  time,  the  Required  Lenders  will  confirm  in  writing  the  Administrative  Agent’s  authority  to
release  or  subordinate  its  interest  in  particular  types  or  items  of  property,  or  to  release  any  Guarantor  from  its  obligations  under  the  Guaranty,
pursuant to this Section 11.09. At any time that a Loan Party desires the Administrative Agent to take any action pursuant to this Section 11.09,
such Loan Party shall deliver a certificate signed by a Responsible Officer of such Loan Party stating that the action is permitted pursuant to this
Section 11.09 and the terms of this Agreement.

The  Administrative  Agent  shall  not  be  responsible  for  or  have  a  duty  to  ascertain  or  inquire  into  any  representation  or  warranty  regarding  the
existence,  value  or  collectability  of  the  Collateral,  the  existence,  priority  or  perfection  of  the  Administrative  Agent’s  Lien  thereon,  or  any
certificate prepared by any Loan Party in connection therewith, nor shall the Administrative Agent be responsible or liable to the Lenders for any
failure to monitor or maintain any portion of the Collateral.

any other Loan Party therefrom, shall be effective unless in writing signed by the Required Lenders and the Borrower or the applicable Loan Party, as the
case may be, and acknowledged by the Administrative Agent, and each such waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, further, that:

written consent of such Lender whose Commitment is being extended or increased (it being understood and agreed that a waiver of any condition

it being agreed that (X) all Lenders shall be deemed to be directly and adversely affected by an amendment, waiver or supplement described in the
preceding clause (iv), (v), (vi) or (vii) and (Y) notwithstanding anything to the contrary in the preceding clause (X), only those Lenders that have
not  been  provided  a  reasonable  opportunity,  as  determined  in  the  good  faith  judgment  of  Administrative  Agent,  to  receive  the  most-favorable
treatment under or in connection with the applicable amendment, waiver or supplement described in the preceding clause (iv), (v), (vi) or (vii)
(other  than  the  right  to  receive  customary  administrative  agency,  arranging,  underwriting  and  other  similar  fees)  that  is  provided  to  any  other
Person, including the opportunity to participate on a pro rata basis on the same terms in any new loans or other Indebtedness permitted to be issued
as  a  result  of  such  amendment,  waiver  or  supplement,  shall  be  deemed  to  be  directly  and  adversely  affected  by  such  amendment,  waiver  or
supplement; and

(b)        unless  also  signed  by  the  Administrative  Agent,  no  amendment,  waiver  or  consent  shall  affect  the  rights  or  duties  of  the
Administrative Agent under this Agreement or any other Loan Document; provided, however, that, notwithstanding anything to the contrary herein, (i) no
Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment, waiver or consent
which  by  its  terms  requires  the  consent  of  all  Lenders  or  each  affected  Lender  may  be  effected  with  the  consent  of  the  applicable  Lenders  other  than
Defaulting Lenders), except that (x) the Commitment of any Defaulting Lender may not be increased or extended without the consent of such Lender and
(y) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender
more adversely than other affected Lenders shall require the consent of such Defaulting Lender, (ii) each Lender is entitled to vote as such Lender sees fit
on any bankruptcy reorganization plan that affects the Loans, and each Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy
Code of the United States supersedes the unanimous consent provisions set forth herein and (iii) the Required Lenders shall determine whether or not to
allow a Loan Party to use cash collateral in the context of a bankruptcy or insolvency proceeding and such determination shall be binding on all of the

Notwithstanding anything to the contrary contained herein, (i) the Administrative Agent and the Borrower may make amendments contemplated by Section
10.03, (ii) the Borrowers and the Administrative Agent may, without the input or consent of any other Lender, make technical, administrative or operational
amendments to the Loan Documents as are advisable in their good faith judgment in connection with (A) the addition of Non-U.S. Subsidiaries as Loan
Parties  and  (B)  the  inclusion  of  the  assets  of  such  Non-U.S.  Subsidiaries  as  Collateral,  (iii)  if  the  Administrative  Agent  and  the  Borrower  have  jointly
identified an obvious error or any error or omission of a technical or immaterial nature, in each case, in any provision of the Loan Documents (including,
for  the  avoidance  of  doubt,  any  exhibit,  schedule  or  annex  thereto),  then  the  Administrative  Agent  and  the  Borrower  shall  be  permitted  to  amend  such
provision and such amendment shall become effective without any further action or consent of any other party to any Loan Document.

been given when received; notices and other communications sent by facsimile shall be deemed to have been given when sent (except that, if not given
during normal business hours for the recipient, shall be deemed to have been given at the opening of business on the next Business Day for the recipient).
Notices  and  other  communications  delivered  through  electronic  communications  to  the  extent  provided  in  subsection  (b)  below,  shall  be  effective  as
provided in such subsection (b).

(b)        Electronic  Communications.  Notices  and  other  communications  to  the  Lenders  hereunder  may  be  delivered  or  furnished  by

accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it, provided, that, approval of
such procedures may be limited to particular notices or communications.

Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received
upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail
or other written acknowledgement), and (ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed
receipt by the intended recipient at its e-mail address as described in the foregoing clause (i) of notification that such notice or communication is available

normal  business  hours  of  the  recipient,  such  notice,  email  or  communication  shall  be  deemed  to  have  been  sent  at  the  opening  of  business  on  the  next
business day for the recipient.

(c)        Change of Address, Etc.  Each  of  the  Borrower,  other  Loan  Parties,  the  Lenders  and  the  Administrative  Agent  may  change  its
address, facsimile or telephone number for notices and other communications hereunder by notice to the other parties hereto. In addition, each Lender
agrees to notify the Administrative Agent from time to time to ensure that the Administrative Agent has on record (i) an effective address, contact name,
telephone  number,  facsimile  number  and  electronic  mail  address  to  which  notices  and  other  communications  may  be  sent  and  (ii)  accurate  wire
instructions for such Lender.

(d)    Reliance by Administrative Agent and Lenders. The Administrative Agent and the Lenders shall be entitled to rely and act upon
any notices (including telephonic or electronic Loan Notices) purportedly given by or on behalf of any Loan Party even if (i) such notices were not made
in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as
understood  by  the  recipient,  varied  from  any  confirmation  thereof.  The  Loan  Parties  shall  indemnify  the  Administrative  Agent,  each  Lender  and  the
Related Parties of each of them from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given
by or on behalf of a Loan Party. All telephonic notices to and other telephonic communications with the Administrative Agent may be recorded by the
Administrative Agent, and each of the parties hereto hereby consents to such recording.

12.03    No Waiver; Cumulative Remedies; Enforcement.

No failure by any Lender or the Administrative Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or
privilege hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power
or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein provided, and provided under each other Loan Document, are cumulative and not exclusive of any rights, remedies, powers
and privileges provided by law.

Notwithstanding anything to the contrary contained herein or in any other Loan Document, the authority to enforce rights and remedies hereunder
and  under  the  other  Loan  Documents  against  the  Loan  Parties  or  any  of  them  shall  be  vested  exclusively  in,  and  all  actions  and  proceedings  at  law  in
connection with such enforcement shall be instituted and maintained exclusively by, the Administrative Agent in accordance with Section 11.01  for  the
benefit of all the Secured Parties; provided, however, that, the foregoing shall not prohibit (a) the Administrative Agent from exercising on its own behalf
the rights and remedies that inure to its benefit (solely in its capacity as Administrative Agent) hereunder and under the other Loan Documents, (b) any
Lender from exercising setoff rights in accordance with Section 12.08 (subject to the terms of Section 2.11), or (c) any Lender from filing proofs of claim
or  appearing  and  filing  pleadings  on  its  own  behalf  during  the  pendency  of  a  proceeding  relative  to  any  Loan  Party  under  any  Debtor  Relief  Law;  and
provided, further, that,  if  at  any  time  there  is  no  Person  acting  as  Administrative  Agent  hereunder  and  under  the  other  Loan  Documents,  then  (i)  the
Required Lenders shall have the rights otherwise ascribed to the Administrative Agent pursuant to Section 11.01 and (ii) in addition to the matters set forth
in clauses (b) and (c) of the preceding proviso and subject to Section 2.11, any Lender may, with the consent of the Required Lenders, enforce any rights
and remedies available to it and as authorized by the Required Lenders.

Lender),  in  connection  with  (A)  the  preparation,  negotiation,  execution  and  delivery  of  this  Agreement  and  the  other  Loan  Documents  and  (B)  any
amendments,  modifications  or  waivers  of  the  provisions  hereof  or  thereof  (whether  or  not  the  transactions  contemplated  hereby  or  thereby  shall  be
consummated) or the administration of this Agreement and the other Loan Documents and (ii) all out-of-pocket expenses incurred by the Administrative
Agent or any Lender (including the fees, charges and disbursements of any counsel for the Administrative Agent or any Lender) in connection with the
enforcement or protection of its rights (A) in connection with this Agreement and the other Loan Documents, including its rights under this Section, or (B)

respect of such Loans.

129

 
 
 
 
 
 
 
(b)    Indemnification by the Loan Parties. The Loan Parties shall indemnify the Administrative Agent (and any sub-agent thereof) and
each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee
harmless  from,  any  and  all  losses,  claims,  damages,  liabilities  and  related  expenses  (including  the  reasonable  fees,  charges  and  disbursements  of  any
counsel for any Indemnitee), and shall indemnify and hold harmless each Indemnitee from all fees and time charges and disbursements for attorneys who
may be employees of any Indemnitee, incurred by any Indemnitee or asserted against any Indemnitee by any Person (including the Borrower or any other

agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or
the  consummation  of  the  transactions  contemplated  hereby  or  thereby,  or,  in  the  case  of  the  Administrative  Agent  (and  any  sub-agent  thereof)  and  its
Related  Parties  only,  the  administration  of  this  Agreement  and  the  other  Loan  Documents,  (ii)  any  Loan  or  the  use  or  proposed  use  of  the  proceeds
therefrom, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by a Loan Party or any of its
Subsidiaries, or any Environmental Liability related in any way to a Loan Party or any of its Subsidiaries, or (iv) [***] or (vii) any actual or prospective
claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a
third party or by the Borrower or any other Loan Party, and regardless of whether any Indemnitee is a party thereto, in all cases, whether or not caused by
or arising, in whole or in part, out of the comparative, contributory or sole negligence of the Indemnitee; provided, that, such indemnity shall not, as to
any  Indemnitee,  be  available  to  the  extent  that  such  losses,  claims,  damages,  liabilities  or  related  expenses  are  determined  by  a  court  of  competent
jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee, if the Borrower or
other Loan Party has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction. Clauses
(a) and (b) of this Section 12.04 shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any
non-Tax claim.

(c)    Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, the Borrower shall (and shall cause each
Subsidiary to) not assert, and the Borrower hereby waives, and acknowledges that no other Person shall have, any claim against any Indemnitee, on any
theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as
a  result  of,  this  Agreement,  any  other  Loan  Document  or  any  agreement  or  instrument  contemplated  hereby,  the  transactions  contemplated  hereby  or
thereby, any Loan or the use of the proceeds thereof. No Indemnitee referred to in subsection (b) above shall be liable for any damages arising from the
use  by  unintended  recipients  of  any  information  or  other  materials  distributed  by  it  through  telecommunications,  electronic  or  other  information
transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

(d)    Reimbursement by Lenders. To the extent that the Loan Parties for any reason fail to indefeasibly pay any amount required under
subsection (a) or (b) of this Section to be paid by them to the Administrative Agent (or any sub-agent thereof) or any Related Party thereof, each Lender
severally  agrees  to  pay  to  the  Administrative  Agent  (or  any  such  sub-agent)  or  such  Related  Party,  as  the  case  may  be,  such  Lender’s  pro rata  share
(determined as of the time that the applicable unreimbursed expense or indemnity payment is sought based on each Lender’s share of the Total Credit
Exposure at such time) of such unpaid amount (including any such unpaid amount in respect of a claim asserted by such Lender), such payment to be
made  severally  among  them  based  on  such  Lender’s  Applicable  Percentage  (determined  as  of  the  time  that  the  applicable  unreimbursed  expense  or
indemnity payment is sought), provided, further, that, the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the
case may be, was incurred by or asserted against the Administrative Agent (or any such sub-agent), or against any Related Party thereof acting for the
Administrative Agent (or any such sub-agent) in connection with such capacity. The obligations of the Lenders under this subsection (d) are subject to the
provisions of Section 2.10(b).

130

 
 
 
 
 
(e)    Payments. All amounts due under this Section shall be payable not later than five (5) Business Days after demand therefor.

(f)        Survival.  The  agreements  in  this  Section  and  the  indemnity  provisions  of  Section 12.02(d)  shall  survive  the  resignation  of  the
Administrative Agent, the replacement of any Lender, the termination of the Commitments and the repayment, prepayment, satisfaction or discharge of all
the other Obligations.

12.05    Marshalling; Payments Set Aside.

None  of  the  Administrative  Agent  or  the  Lenders  shall  be  under  any  obligation  to  marshal  any  assets  in  favor  of  any  Loan  Party  or  any  other
Person  or  against  or  in  payment  of  any  or  all  of  the  Obligations.  To  the  extent  that  any  payment  by  or  on  behalf  of  any  Loan  Party  is  made  to  the
Administrative Agent or any Lender, or the Administrative Agent or any Lender exercises its right of setoff, and such payment or the proceeds of such
setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement
entered  into  by  the  Administrative  Agent  or  such  Lender  in  its  discretion)  to  be  repaid  to  a  trustee,  receiver  or  any  other  party,  in  connection  with  any
proceeding  under  any  Debtor  Relief  Law  or  otherwise,  then  (a)  to  the  extent  of  such  recovery,  the  obligation  or  part  thereof  originally  intended  to  be
satisfied, and all Liens, rights and remedies therefor or related thereto, shall be revived and continued in full force and effect as if such payment had not
been  made  or  such  setoff  had  not  occurred,  and  (b)  each  Lender  severally  agrees  to  pay  to  the  Administrative  Agent  upon  demand  its  applicable  share
(without duplication) of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the
date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Lenders under clause (b)
of the preceding sentence shall survive the payment in full of the Obligations and the termination of this Agreement.

12.06    Successors and Assigns; Transfers.

(a)    Successors and Assigns Generally. The provisions of this Agreement and the other Loan Documents shall be binding upon and
inure to the benefit of the parties hereto and thereto and their respective successors and assigns permitted hereby, except that the Borrower and the other
Loan Parties may not assign or otherwise transfer any of their respective rights or obligations hereunder or thereunder without the prior written consent of
the  Administrative  Agent  and  each  Lender  and  no  Lender  may  assign  or  otherwise  transfer  any  of  its  rights  or  obligations  hereunder  except  (i)  to  an
assignee in accordance with the provisions of clause (b) of this Section, (ii) by way of participation in accordance with the provisions of clause (d) of this
Section  or  (iii)  by  way  of  pledge  or  assignment  of  a  security  interest  subject  to  the  restrictions  of  clause  (e)  of  this  Section  (and  any  other  attempted
assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any
Person  (other  than  the  parties  hereto,  their  respective  successors  and  assigns  permitted  hereby,  Participants  to  the  extent  provided  in  clause (d)  of  this
Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

131

 
 
 
 
 
 
 
 
(b)    Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations
under this Agreement and the other Loan Documents (including all or a portion of its Commitments under any Facility and the Loans at the time owing to
it (in each case with respect to any Facility)); provided, that, any such assignment shall be subject to the following conditions:

(i)    Minimum Amounts.

(A)         in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment with respect to
any Facility and/or the Loans with respect to any Facility at the time owing to it or contemporaneous assignments to related Approved
Funds that equal at least the amount specified in paragraph (b)(i)(B) of this Section in the aggregate or in the case of an assignment to
a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B)         in any case not described in clause (b)(i)(A) of this Section, the aggregate amount of the applicable Commitment
(which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal
outstanding balance of the Loans with respect to any Facility of the assigning Lender subject to each such assignment, determined as
of  the  date  the  Assignment  and  Assumption  with  respect  to  such  assignment  is  delivered  to  the  Administrative  Agent  or,  if  “Trade
Date”  is  specified  in  the  Assignment  and  Assumption,  as  of  the  Trade  Date,  shall  not  be  less  than  $[***]  unless  each  of  the
Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such
consent not to be unreasonably withheld or delayed);

(ii)        Proportionate Amounts.  Each  partial  assignment  shall  be  made  as  an  assignment  of  a  proportionate  part  of  all  of  the  assigning

Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned;

(iii)        Required Consents.  No  consent  shall  be  required  for  any  assignment  except  to  the  extent  required  by  clause  (b)(i)(B)  of  this

Section and, in addition:

(A)         the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (1)
an Event of Default has occurred and is continuing at the time of such assignment or (2) such assignment is to a Lender, an
Affiliate  of  a  Lender  or  an  Approved  Fund;  provided, that,  the  Borrower  shall  be  deemed  to  have  consented  to  any  such
assignment unless it shall object thereto by written notice to the Administrative Agent within five (5) Business Days after
having received notice thereof;

(B)         the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required
for assignments in respect of (i) any unfunded Commitment if such assignment is to a Person that is not a Lender with a Commitment in
respect of the applicable Facility, an Affiliate of such Lender or an Approved Fund with respect to such Lender or (ii) any Loan to a
Person that is not a Lender, an Affiliate of a Lender or an Approved Fund;

132

 
 
 
 
 
 
 
 
 
 
(iv)    Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment
and Assumption. The assignee, if it is not a Lender, shall deliver to the Administrative Agent such information, including notice information, as
the Administrative Agent shall reasonably require.

(v)    No Assignment to Certain Persons. No such assignment shall be made (A) to the Borrower or any of the Borrower’s Affiliates or
Subsidiaries, (B) to any Defaulting Lender or any of its Subsidiaries or any Person who, upon becoming a Lender hereunder, would constitute any
of the foregoing Persons described in this clause (B) or (C) to a natural Person.

(vi)    Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no
such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall
make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which
may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with
the  consent  of  the  Borrower  and  the  Administrative  Agent,  the  applicable  pro  rata  share  of  Loans  previously  requested  but  not  funded  by  the
Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment
liabilities  then  owed  by  such  Defaulting  Lender  to  the  Administrative  Agent  or  any  Lender  hereunder  (and  interest  accrued  thereon)  and  (y)
acquire (and fund as appropriate) its full pro rata share of all Loans in accordance with its Applicable Percentage. Notwithstanding the foregoing,
in  the  event  that  any  assignment  of  rights  and  obligations  of  any  Defaulting  Lender  hereunder  shall  become  effective  under  applicable  Law
without  compliance  with  the  provisions  of  this  paragraph,  then  the  assignee  of  such  interest  shall  be  deemed  to  be  a  Defaulting  Lender  for  all
purposes of this Agreement until such compliance occurs.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to clause (c) of this Section, from and after the effective date specified in
each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment
and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest
assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption
covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be
entitled to the benefits of Sections 3.01, 10.01 and 11.04 with respect to facts and circumstances occurring prior to the effective date of such assignment.
Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of rights or
obligations  under  this  Agreement  that  does  not  comply  with  this  clause  shall  be  treated  for  purposes  of  this  Agreement  as  a  sale  by  such  Lender  of  a
participation in such rights and obligations in accordance with clause (d) of this Section.

(c)    Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower, shall maintain at the
Administrative Agent’s Office a copy of each Assignment and Assumption delivered to it (or the equivalent thereof in electronic form) and a register for
the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Loans owing to,
each Lender pursuant to the terms hereof from time to time (the “Register”). Notwithstanding anything to the contrary in any Loan Document, the entries
in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name
is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. In addition, the Administrative Agent
shall maintain on the Register information regarding the designation, and revocation of designation, of any Lender as a Defaulting Lender. The Register
shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

133

 
 
 
 
 
 
 
(d)    Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell
participations  to  any  Person  (other  than  a  natural  Person,  a  Defaulting  Lender  (or  a  holding  company,  investment  vehicle  or  trust  for,  or  owned  and
operated for the primary benefit of a natural Person) or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a
portion  of  such  Lender’s  rights  and/or  obligations  under  this  Agreement  (including  all  or  a  portion  of  its  Commitments  and/or  Loans  owing  to  it);
provided, that, (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely
and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender
shall be responsible for the indemnity under Section 12.04(d) without regard to the existence of any participation.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to
enforce  this  Agreement  and  to  approve  any  amendment,  modification  or  waiver  of  any  provision  of  this  Agreement;  provided, that,  such  agreement  or
instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described
in clauses (i) through (vi) of Section 12.01(a) that affects such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of
Section  3.01  (subject  to  the  requirements  and  limitations  therein  (it  being  understood  that  the  documentation  required  under  Section  3.01(f)  shall  be
delivered to the participating Lender)) and Section 10.01 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to
paragraph (b) of this Section; provided, that, such Participant (A) agrees to be subject to the provisions of Sections 10.02 and 12.13 as if it were an assignee
under  paragraph  (b)  of  this  Section  and  (B)  shall  not  be  entitled  to  receive  any  greater  payment  under  Section  3.01  or  10.01,  with  respect  to  any
participation, than the Lender from whom it acquired the applicable participation would have been entitled to receive, except to the extent such entitlement
to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a
participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section
12.02 with respect to any Participant. To the fullest extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though
it were a Lender; provided, that, such Participant agrees to be subject to Section 2.11 as though it were a Lender. Each Lender that sells a participation
shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant
and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant
Register”); provided, that,  no  Lender  shall  have  any  obligation  to  disclose  all  or  any  portion  of  the  Participant  Register  (including  the  identity  of  any
Participant  or  any  information  relating  to  a  Participant’s  interest  in  any  commitments,  loans  or  its  other  obligations  under  any  Loan  Document)  to  any
Person except to the extent that such disclosure is necessary to establish that such commitment, loan or other obligation is in registered form under Section
5f.103-1(c) of the Treasury Regulations. Notwithstanding anything to the contrary in any Loan Document, the entries in the Participant Register shall be
conclusive  absent  manifest  error,  and  such  Lender  shall  treat  each  Person  whose  name  is  recorded  in  the  Participant  Register  as  the  owner  of  such
participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its
capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

134

 
 
 
 
(e)        Certain Pledges.  Any  Lender  may  at  any  time  pledge  or  assign  a  security  interest  in  all  or  any  portion  of  its  rights  under  this
Agreement (including under its Note, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal
Reserve Bank; provided, that, no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee
or assignee for such Lender as a party hereto.

12.07    Treatment of Certain Information; Confidentiality.

Each  of  the  Administrative  Agent  and  the  Lenders  agrees  to  maintain  the  confidentiality  of  the  Information  (as  defined  below),  except  that
Information may be disclosed (a) to its Affiliates and to its Related Parties (it being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent required or requested by any
regulatory authority purporting to have jurisdiction over such Person or its Related Parties (including any self-regulatory authority, such as the National
Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to
any other party hereto, (e) as may be reasonably necessary in connection with the exercise of any remedies hereunder or under any other Loan Document or
any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an
agreement containing provisions substantially the same as those of this Section, to (i) any Participant, assignee or transferee (or its Related Parties) of, or
any prospective Participant, assignee or transferee (or its Related Parties) of, any of its rights and obligations under this Agreement or (ii) any actual or
prospective party (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to a Loan Party and
its obligations, this Agreement or payments hereunder, (g) on a confidential basis to (i) any rating agency in connection with rating the Borrower or its
Subsidiaries  or  the  credit  facilities  provided  hereunder  or  (ii)  the  CUSIP  Service  Bureau  or  any  similar  agency  in  connection  with  the  issuance  and
monitoring of CUSIP numbers or other market identifiers with respect to the credit facilities provided hereunder, (h) with the consent of the Borrower, (i) to
the members of its investment committee (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature
of such Information and instructed to keep such Information confidential) or (j) to the extent such Information (x) becomes publicly available other than as
a  result  of  a  breach  of  this  Section  or  (y)  becomes  available  to  the  Administrative  Agent,  any  Lender  or  any  of  their  respective  Affiliates  on  a
nonconfidential basis from a source other than the Loan Parties.

For purposes of this Section, “Information” means all information received from a Loan Party or any Subsidiary relating to the Loan Parties or any
Subsidiary  or  any  of  their  respective  businesses,  other  than  any  such  information  that  is  available  to  the  Administrative  Agent  or  any  Lender  on  a
nonconfidential basis, provided, that, in the case of information received from a Loan Party or any Subsidiary after the date hereof, such information is
clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall
be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such
Information as such Person would accord to its own confidential information.

135

 
 
 
 
 
 
12.08    Set-off.

If an Event of Default shall have occurred and be continuing, each Lender and each of their respective Affiliates is hereby authorized at any time
and from time to time, after obtaining the prior written consent of the Administrative Agent, to the fullest extent permitted by applicable law, to set off and
apply  any  and  all  deposits  (general  or  special,  time  or  demand,  provisional  or  final,  in  whatever  currency)  at  any  time  held  and  other  obligations  (in
whatever currency) at any time owing by such Lender or any such Affiliate to or for the credit or the account of the Borrower or any other Loan Party
against any and all of the obligations of the Borrower or such Loan Party now or hereafter existing under this Agreement or any other Loan Document to
such Lender or its Affiliates, irrespective of whether or not such Lender or Affiliate shall have made any demand under this Agreement or any other Loan
Document and although such obligations of the Borrower or such Loan Party may be contingent or unmatured or are owed to a branch office or Affiliate of
such  Lender  different  from  the  branch  office  or  Affiliate  holding  such  deposit  or  obligated  on  such  indebtedness;  provided, that,  in  the  event  that  any
Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further
application in accordance with the provisions of Section 2.12 and, pending such payment, shall be segregated by such Defaulting Lender from its other
funds and deemed held in trust for the benefit of the Administrative Agent and the Lenders and (y) the Defaulting Lender shall provide promptly to the
Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of
setoff. The rights of each Lender and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of
setoff) that such Lender or their respective Affiliates may have. Each Lender agrees to notify the Borrower and the Administrative Agent promptly after
any such setoff and application, provided, that, the failure to give such notice shall not affect the validity of such setoff and application.

12.09    Interest Rate Limitation.

Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall
not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender shall
receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid
principal,  refunded  to  the  Borrower.  In  determining  whether  the  interest  contracted  for,  charged,  or  received  by  the  Administrative  Agent  or  a  Lender
exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense,
fee,  or  premium  rather  than  interest,  (b)  exclude  voluntary  repayments  or  prepayments  and  the  effects  thereof,  and  (c)  amortize,  prorate,  allocate,  and
spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

12.10    Counterparts; Integration; Effectiveness.

This Agreement and each of the other Loan Documents may be executed in counterparts (and by different parties hereto in different counterparts),
each  of  which  shall  constitute  an  original,  but  all  of  which  when  taken  together  shall  constitute  a  single  contract.  This  Agreement,  the  other  Loan
Documents, and any separate letter agreements with respect to fees payable to Athyrium or its Affiliates, the Lenders or Administrative Agent, constitute
the  entire  contract  among  the  parties  relating  to  the  subject  matter  hereof  and  supersede  any  and  all  previous  agreements  and  understandings,  oral  or
written, relating to the subject matter hereof. Except as provided in Section 5.01, this Agreement shall become effective when it shall have been executed
by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of
each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by fax transmission or e-mail transmission (e.g.,
“pdf” or “tif”) shall be effective as delivery of a manually executed counterpart of this Agreement or such other Loan Documents or certificate. Without
limiting the foregoing, to the extent a manually executed counterpart is not specifically required to be delivered under the terms of any Loan Document,
upon the request of any party, such fax transmission or e-mail transmission shall be promptly followed by such manually executed counterpart.

136

 
 
 
 
 
 
 
 
12.11    Survival of Representations and Warranties.

All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in
connection herewith or therewith shall survive the execution and delivery hereof and thereof and shall continue in full force and effect as long as any Loan
or  other  Obligation  hereunder  shall  remain  unpaid  or  unsatisfied  and  until  all  of  the  Commitments  have  been  terminated  in  accordance  with  the  terms
hereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation
made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice
or knowledge of any Default at the time of any Borrowing, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder
shall remain unpaid or unsatisfied and until all of the Commitments have been terminated in accordance with the terms hereof.

12.12    Severability.

If any provision (or portion of a provision) of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (a) the
legality, validity and enforceability of the remaining provisions (or portion of such provision) of this Agreement and the other Loan Documents shall not
be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions (or
portions of such provisions) with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable
provisions (or portion of such provisions). The invalidity of a provision (or portion of a provision)  in  a  particular  jurisdiction  shall  not  invalidate  or
render unenforceable such provision (or portion of such provision) in any other jurisdiction. Without limiting the foregoing provisions of this Section
12.12, if and to the extent that the enforceability of any provisions (or portions of such provisions) in this Agreement relating to Defaulting Lenders shall
be limited by Debtor Relief Laws, as determined in good faith by the Administrative Agent, then such provisions (or portions of such provisions) shall be
deemed to be in effect only to the extent not so limited.

12.13    Replacement of Lenders.

If the Borrower is entitled to replace a Lender pursuant to the provisions of Section 10.02  or  if  any  Lender  is  a  Defaulting  Lender  or  a  Non-
Consenting Lender, then the Borrower may, at its sole expense and effort, upon written notice to such Lender and the Administrative Agent, require such
Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 12.06),
all  of  its  interests,  rights  (other  than  its  existing  rights  to  payments  pursuant  to  Sections 3.01 and 10.01)  and  obligations  under  this  Agreement  and  the
related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment),
provided, that:

137

 
 
 
 
 
 
 
 
(a)    such Lender shall have received payment of an amount equal to one hundred percent (100%) of (x) the outstanding principal of its
Loans, accrued interest thereon and all other amounts payable to it hereunder and under the other Loan Documents (other than repayment or prepayment
premiums or the exit fee) from the assignee (to the extent of such outstanding principal and accrued interest) or the Borrower (in the case of all other
amounts) and (y) the repayment or prepayment premium required by Section 2.03(d) and the exit fee required under Section 2.07(b) in each case, from the
Borrower, as if such assignment was a prepayment of one hundred percent (100%) of the outstanding principal amount of such assignor’s Loans on the
effective date of such assignment;

(b)    such assignment does not conflict with applicable Laws;

pursuant to Section 3.01, such assignment will result in a reduction in such compensation or payments thereafter; and

(c)    in the case of any such assignment resulting from a claim for compensation under Section 10.01 or payments required to be made

(d)    in the case of any such assignment resulting from a Non-Consenting Lender’s failure to consent to a proposed change, waiver,
discharge  or  termination  with  respect  to  any  Loan  Document,  the  applicable  replacement  bank,  financial  institution  or  Fund  consents  to  the  proposed
change, waiver, discharge or termination; provided, that, the failure by any Defaulting Lender or any Non-Consenting Lender to execute and deliver an
Assignment  and  Assumption  shall  not  impair  the  validity  of  the  removal  of  such  Defaulting  Lender  or  Non-Consenting  Lender  and  the  mandatory
assignment  of  such  Defaulting  Lender  or  Non-Consenting  Lender’s  outstanding  Loans  pursuant  to  this  Section  12.13  shall  nevertheless  be  effective
without the execution by such Defaulting Lender or Non-Consenting Lender of an Assignment and Assumption.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise,

the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

12.14    Governing Law; Jurisdiction; Etc.

(a)    GOVERNING LAW. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (EXCEPT, AS TO ANY OTHER LOAN
DOCUMENT, AS EXPRESSLY SET FORTH THEREIN) AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSE OF ACTION (WHETHER

IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM
TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

(d)        SERVICE  OF  PROCESS.  EACH  PARTY  HERETO  IRREVOCABLY  CONSENTS  TO  SERVICE  OF  PROCESS  IN  THE
MANNER  PROVIDED  FOR  NOTICES  IN  SECTION  12.02.  NOTHING  IN  THIS  AGREEMENT  WILL  AFFECT  THE  RIGHT  OF  ANY  PARTY
HERETO TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

12.15        Waiver  of  Right  to  Trial  by  Jury.  EACH  PARTY  HERETO  HEREBY  IRREVOCABLY  WAIVES,  TO  THE  FULLEST  EXTENT
PERMITTED  BY  APPLICABLE  LAW,  ANY  RIGHT  IT  MAY  HAVE  TO  A  TRIAL  BY  JURY  IN  ANY  LEGAL  PROCEEDING  DIRECTLY  OR

OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER
AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND
THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

12.16    Judgment Currency.

(a)        If,  for  the  purpose  of  obtaining  judgment  in  any  court,  it  is  necessary  to  convert  a  sum  owing  hereunder  in  one  currency  into
another  currency,  each  party  hereto  agrees,  to  the  fullest  extent  that  it  may  effectively  do  so,  that  the  rate  of  exchange  used  shall  be  that  at  which  in
accordance with normal banking procedures in the relevant jurisdiction the first currency could be purchased with such other currency on the Business
Day immediately preceding the day on which final judgment is given.

139

 
 
 
 
 
 
 
(b)    The obligations of the Loan Parties in respect of any sum due to any party hereto or any holder of the Obligations owing hereunder
(the “Applicable Creditor”) shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than the currency in which such sum is
stated to be due hereunder (the “Agreement Currency”), be discharged only to the extent that, on the Business Day following receipt by the Applicable
Creditor of any sum adjudged to be so due in the Judgment Currency, the Applicable Creditor may in accordance with normal banking procedures in the
relevant jurisdiction purchase the Agreement Currency with the Judgment Currency; if the amount of the Agreement Currency so purchased is less than
the sum originally due to the Applicable Creditor in the Agreement Currency, the Loan Parties agree, as a separate obligation and notwithstanding any
such judgment, to jointly and severally indemnify the Applicable Creditor against such loss. The obligations of the Borrower contained in this Section
12.16 shall survive the termination of this Agreement, the termination of the Commitments and the payment of all other amounts owing hereunder.

12.17    Electronic Execution of Assignments and Certain Other Documents.

This Agreement and any document, amendment, approval, consent, information, notice, certificate, request, statement, disclosure or authorization
related to this Agreement (each a “Communication”), including Communications required to be in writing, may be in the form of an Electronic Record and
may be executed using Electronic Signatures. Each of the Loan Parties agrees that any Electronic Signature on or associated with any Communication shall
be valid and binding on each of the Loan Parties to the same extent as a manual, original signature, and that any Communication entered into by Electronic
Signature, will constitute the legal, valid and binding obligation of each of the Loan Parties enforceable against such in accordance with the terms thereof to
the same extent as if a manually executed original signature was delivered. Any Communication may be executed in as many counterparts as necessary or
convenient, including both paper and electronic counterparts, but all such counterparts are one and the same Communication. For the avoidance of doubt,
the  authorization  under  this  paragraph  may  include,  without  limitation,  use  or  acceptance  by  the  Administrative  Agent  and  each  of  the  Lenders  of  a
manually  signed  paper  Communication  which  has  been  converted  into  electronic  form  (such  as  scanned  into  PDF  format),  or  an  electronically  signed
Communication converted into another format, for transmission, delivery and/or retention. The Administrative Agent and each of the Lenders may, at its
option, create one or more copies of any Communication in the form of an imaged Electronic Record (“Electronic Copy”), which shall be deemed created
in the ordinary course of the such Person’s business, and destroy the original paper document. All Communications in the form of an Electronic Record,
including an Electronic Copy, shall be considered an original for all purposes, and shall have the same legal effect, validity and enforceability as a paper
record. Notwithstanding anything contained herein to the contrary, the Administrative Agent is under no obligation to accept an Electronic Signature in any
form or in any format unless expressly agreed to by the Administrative Agent pursuant to procedures approved by it; provided, further, without limiting the
foregoing, (a) to the extent the Administrative Agent has agreed to accept such Electronic Signature, the Administrative Agent and each of the Lenders
shall be entitled to rely on any such Electronic Signature purportedly given by or on behalf of any Loan Party without further verification and (b) upon the
request  of  the  Administrative  Agent  or  any  Lender,  any  Electronic  Signature  shall  be  promptly  followed  by  such  manually  executed  counterpart.  For
purposes hereof, “Electronic Record” and “Electronic Signature” shall have the meanings assigned to them, respectively, by 15 USC §7006, as it may be
amended from time to time.

140

 
 
 
 
 
12.18    USA PATRIOT Act.

Each Lender that is subject to the PATRIOT Act and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the
Borrower that pursuant to the requirements of the PATRIOT Act, it is required to obtain, verify and record information that identifies each Loan Party,
which information includes the name and address of each Loan Party and other information that will allow such Lender or the Administrative Agent, as
applicable,  to  identify  each  Loan  Party  in  accordance  with  the  PATRIOT  Act.  Each  of  the  Loan  Parties  agrees  to,  promptly  following  a  request  by  the
Administrative Agent or any Lender, provide all such other documentation and information that the Administrative Agent or such Lender requests in order
to comply with its ongoing obligations under applicable “know your customer” and anti-money laundering rules and regulations, including the PATRIOT
Act.

12.19    No Advisory or Fiduciary Relationship.

In  connection  with  all  aspects  of  each  transaction  contemplated  hereby  (including  in  connection  with  any  amendment,  waiver  or  other
modification hereof or of any other Loan Document), the Borrower acknowledges and agrees, and acknowledges its Affiliates’ understanding, that: (a)(i)
the arranging and other services regarding this Agreement provided by the Administrative Agent, Athyrium and its Affiliates, and the Lenders are arm’s-
length commercial transactions between the Borrower and its Affiliates, on the one hand, and the Administrative Agent, Athyrium and its Affiliates and the
Lenders on the other hand, (ii) the Borrower has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate,
and (iii) the Borrower is capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby and by
the other Loan Documents; (b)(i) the Administrative Agent, Athyrium and its Affiliates and each Lender is and has been acting solely as a principal and,
except as expressly agreed in writing by the relevant parties, has not been, is not and will not be acting as an advisor, agent or fiduciary, for the Borrower or
any of its Affiliates or any other Person and (ii) neither the Administrative Agent nor any Lender has any obligation to the Borrower or any of its Affiliates
with  respect  to  the  transactions  contemplated  hereby  except  those  obligations  expressly  set  forth  herein  and  in  the  other  Loan  Documents;  and  (c)  the
Administrative  Agent,  Athyrium  and  its  Affiliates  and  the  Lenders  and  their  respective  Affiliates  may  be  engaged  in  a  broad  range  of  transactions  that
involve interests that differ from those of the Borrower and its Affiliates, and neither the Administrative Agent, Athyrium or its Affiliates nor any Lender
has any obligation to disclose any of such interests to the Borrower or its Affiliates. To the fullest extent permitted by law, the Borrower hereby waives and
releases any claims that they may have against the Administrative Agent, Athyrium or its Affiliates or any Lenders with respect to any breach or alleged
breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.

12.20    Acknowledgement and Consent to Bail-In of EEAAffected Financial Institutions.

Notwithstanding  anything  to  the  contrary  in  any  Loan  Document  or  in  any  other  agreement,  arrangement  or  understanding  among  any  such
parties, each party hereto acknowledges that any liability of any Lender that is an EEAAffected Financial Institution arising under any Loan Document, to
the extent such liability is unsecured, may be subject to the write-down and conversion powers of an EEAthe applicable Resolution Authority and agrees
and consents to, and acknowledges and agrees to be bound by (a) the application of any Write-Down and Conversion Powers by an EEAthe applicable

to the date of such payment.

Section 6.3    Disclosures. Except for a press release previously approved in form and substance by the Seller and the Buyer or any other

public announcement using substantially the same text as such press release, neither the Buyer nor the Seller shall, and each party hereto shall cause its
respective Representatives, Affiliates and Affiliates’ Representatives not to issue a press release or other public announcement or otherwise make any
public disclosure with respect to this Agreement or the 2020 Agreement, or the subject matter hereof or thereof, without the prior written consent of the
other party hereto (which consent shall not be unreasonably withheld or delayed), except as may be required by applicable law or stock exchange rule (in
which case the party hereto required to make the press release or other public announcement or disclosure shall allow the other party hereto reasonable time
to comment on, and, if applicable, reasonably direct the disclosing party to seek confidential treatment in respect of portions of, such press release or other
public announcement or disclosure in advance of such issuance).

Section 6.4    Inspections and Audits of the Seller. Following the Closing, upon at least fourteen (14) Business Days written notice and
during normal business hours, no more frequently than once per calendar year, the Buyer may cause an inspection and/or audit by an independent public
accounting firm reasonably acceptable to the Seller to be made of the Seller’s books of account for the three (3) calendar years prior to the audit for the
purpose of determining the correctness of the calculation of the Royalty Payments under this Agreement or the 2020 Agreement. Upon the Buyer’s
reasonable request, no more frequently than once per calendar year while any Out-License remains in effect, the Seller shall use Commercially Reasonable
Efforts to exercise any rights it may have under any Out-License relating to a Product to cause an inspection and/or audit by an independent public
accounting firm to be made of the books of account of any counterparty thereto for the purpose of determining the correctness of the calculation of the
Royalty Payments under this Agreement or the 2020 Agreement. Seller shall notify Buyer in writing if it initiates an inspection and/or audit of the books of
accounts of any counterparty to an Out-License to the extent such inspection and/or audit is related to the Royalty Payments, and shall provide to Buyer a
redacted copy of any report relating thereto within ten (10) Business Days of receipt thereof; provided, that any redactions to such report shall not include
any information necessary to determine the correctness of the calculation of the Royalty Payments made under this Agreement or the 2020 Agreement. All
of the out-of-pocket expenses of any inspection or audit requested by the Buyer hereunder (including the fees and expenses of such independent public
accounting firm designated for such purpose) shall be borne solely by the Buyer, unless the independent public accounting firm determines that Royalty
Payments previously paid to Buyer during the period of the audit were underpaid by an amount greater than [***]% of the Royalty Payments actually paid
during such period, in which case such expenses shall be borne by the Seller. Any such accounting firm or Seller shall not disclose the confidential
information of the Seller or any such Licensee relating to a Product to the Buyer, except to the extent such disclosure is necessary to determine the
correctness of Royalty Payments or otherwise would be included in a Report. All information obtained by the Buyer as a result of any such inspection or
audit shall be Confidential Information subject to  ARTICLE 8. If any audit discloses any underpayments by the Seller to the Buyer, then such
underpayment shall be paid by the Seller to the Buyer within thirty (30) calendar days of it being so disclosed. If any audit discloses any overpayments by
the Seller to the Buyer, then the Seller shall have the right to credit the amount of the overpayment against each subsequent quarterly Royalty Payment due
to the Buyer until the overpayment has been fully applied. If the overpayment is not fully applied prior to the final quarterly Royalty Payment due
hereunder, the Buyer shall promptly refund an amount equal to any such remaining overpayment.

such Patent Rights entitled to such reimbursement under any such In-License or Out-License ) in bringing such action (including all reasonable attorney’s
fees), (ii) any remaining amounts will be reduced, if applicable, to comply with allocation of recovered damages with licensors of such Patent Rights

Buyer will use its commercially reasonable efforts prior to the Closing to take, or cause to be taken, all actions and to do, or cause to be done, all things
reasonably necessary under applicable law to consummate the transactions contemplated by this Agreement. Each of the Buyer and the Seller agrees to
execute and deliver such other documents, certificates, agreements and other writings and to take such other actions as may be reasonably necessary in
order to consummate or implement expeditiously the transactions contemplated by this Agreement.

certificates, agreements and other writings and to take such other actions as may be reasonably necessary in order to give effect to the transactions
contemplated by this Agreement and the 2020 Agreement.

Section 6.12    No Impairment of Revenue Participation Right or Back-Up Security Interest. Notwithstanding anything herein or in the
2020 Agreement to the contrary, the Seller shall not enter into any contracts or arrangements or otherwise knowingly take any action or knowingly fail to
act in a manner that would, individually or in the aggregate, reasonably be expected to materially and adversely affect the Buyer’s interest in the Revenue
Participation Rights or the Back-Up Security Interest. The parties agree that the entry into (i) the Athyrium Loan Documents, (ii) any agreement evidencing
any secured Indebtedness permitted by clause (b)(ii) of the definition of Restricted Indebtedness, (iii) the OMERS Transaction Agreement or (iv) the 2020
Agreement, which shall, in each case, be subject to and in compliance with the Intercreditor Agreement or any Other Intercreditor Agreement, shall be
deemed to not materially and adversely affect the Buyer’s interest in the Revenue Participation Rights or the Back-Up Security Interest

Section 6.13    Certain Tax Matters.

(a)    The Seller and the Buyer agree that for Tax purposes, (a) the Seller and the Buyer shall treat the transactions contemplated by this
Agreement and the 2020 Agreement as sales of the Revenue Participation Rights and (b) any and all amounts remitted by the Seller to the Buyer after the
2020 Closing Date pursuant to this Agreement or the 2020 Agreement shall be treated as received by the Seller as agent for the Buyer. The parties hereto
agree not to take any position that is inconsistent with the provisions of this  Section 6.13(a) on any tax return or in any audit or other tax-related
administrative or judicial proceeding unless the other party hereto has consented in writing (such consent not to be unreasonably withheld, conditioned or
delayed) to such actions. If there is an inquiry by any Governmental Entity of the Buyer or the Seller related to the treatment described in this  Section
6.13(a), the parties hereto shall cooperate with each other in responding to such inquiry in a reasonable manner which is consistent with this  Section
6.13(a).

(b)    Notwithstanding anything to the contrary in this Agreement, each of the Buyer and the Seller shall be entitled to withhold and

deduct (or cause to be withheld and deducted) from any amount payable under this Agreement or the 2020 Agreement to the other party any Tax that the
Buyer or the Seller, as applicable, determines that it is required to withhold and deduct under applicable law, and any such amount withheld and deducted
shall be treated for all purposes of this Agreement as being paid to the other party; provided that each of the Buyer and the Seller shall give the other party
reasonable prior notice and the opportunity, in good faith, to contest and prevent such withholding and deduction. The parties hereto shall use commercially
reasonable efforts to give or cause to be given to the other party hereto such assistance and such information concerning the reasons for withholding or
deduction (including, in reasonable detail, the method of calculation for the deduction or withholding thereof) as may be reasonably necessary to enable the
Buyer or the Seller, as applicable, to claim exemption therefrom, or credit therefor, or relief (whether at source or by reclaim) therefrom, and, in each case,
shall furnish the Buyer or the Seller, as applicable, with proper evidence of the taxes withheld and deducted and remitted to the relevant taxing authority.
The Buyer agrees (i) to notify the Seller in writing if (A) Buyer becomes ineligible to use or deliver the Form W-8BEN-E delivered to the Seller under
 Section 5.2(e), or (B) the Form W-8BEN-E delivered to the Seller under  Section 5.2(e) ceases to be accurate or complete, and (ii) to provide (to the extent
it is legally eligible to do so) any additional Tax forms that the Seller may reasonably request.

(a)    the Seller hereby agrees to indemnify, defend and hold harmless the Buyer and its Affiliates and its and their directors, managers,

trustees, officers, agents and employees (the “Buyer Indemnified Parties”) from, against and in respect of all Losses suffered or incurred by the Buyer
Indemnified Parties to the extent arising out of or resulting from (i) any breach of any of the representations or warranties of the Seller in this Agreement,
and (ii) any breach of any of the covenants or agreements of the Seller in this Agreement; and

(b)    the Buyer hereby agrees to indemnify, defend and hold harmless the Seller and its Affiliates and its and their directors, officers,

agents and employees (the “Seller Indemnified Parties”) from, against and in respect of all Losses suffered or incurred by the Seller Indemnified Parties to

any of the covenants or agreements of the Buyer in this Agreement.

(such Buyer Indemnified Party on the one hand and such Seller Indemnified Party on the other hand being hereinafter referred to as an “Indemnified
Party”), has suffered or incurred any Losses for which indemnification may be sought under this  ARTICLE 7, the Indemnified Party shall so notify the
other party from whom indemnification is sought under this  ARTICLE 7 (the “Indemnifying Party”) promptly in writing describing such Loss, the amount
or estimated amount thereof, if known or reasonably capable of estimation, and the method of computation of such Loss, all with reasonable particularity
and containing a reference to the provisions of this Agreement in respect of which such Loss shall have occurred. If any claim, action, suit or proceeding is
asserted or instituted by or against a Third Party with respect to which an Indemnified Party intends to claim any Loss under this  ARTICLE 7, such
Indemnified Party shall promptly notify the Indemnifying Party of such claim, action, suit or proceeding and tender to the Indemnifying Party the defense
of such claim, action, suit or proceeding. A failure by an Indemnified Party to give notice and to tender the defense of such claim, action, suit or proceeding
in a timely manner pursuant to this  Section 7.2 shall not limit the obligation of the Indemnifying Party under this  ARTICLE 7, except to the extent such
Indemnifying Party is actually prejudiced thereby.

cases of fraud, gross negligence, or willful misconduct, no party hereto shall be liable for any consequential, punitive, special or incidental damages under
this  ARTICLE 7 (and no claim for indemnification hereunder shall be asserted) as a result of any breach or violation of any covenant or agreement of such
party (including under this  ARTICLE 7) in or pursuant to this Agreement. In connection with the foregoing, the parties hereto acknowledge and agree that

respect of its ownership of the Royalty Payments but did not receive timely or at all due to such indemnifiable event and (ii) the Buyer shall be entitled to
make claims for all such missing or delayed Royalty Payments as Losses hereunder, and such missing or delayed Royalty Payments shall not be deemed
consequential, punitive, special, indirect or incidental damages.

after Closing, the rights of the parties hereto pursuant to (and subject to the conditions of) this  ARTICLE 7 shall be the sole and exclusive remedy of the
parties hereto and their respective Affiliates with respect to any Losses (whether based in contract, tort or otherwise) resulting from or relating to any

hereunder, and each party hereto hereby waives, to the fullest extent permitted under applicable law, and agrees not to assert after Closing, any other claim
or action in respect of any such breach. Notwithstanding the foregoing, the rights of Buyer under the Intercreditor Agreement and claims for fraud, gross
negligence, or willful misconduct shall not be waived or limited in any way by this  ARTICLE 7. No party hereto shall be entitled to recover duplicative
Losses for Losses resulting from or relating to any breach of any representations, warranties, covenants or agreements made under this Agreement that also
constitute Losses resulting from or relating to any breach of any representations, warranties, covenants or agreements made under the 2020 Agreement.

this  ARTICLE 7 will be treated as an adjustment to the Purchase Price for U.S. federal income tax to the fullest extent permitted by applicable law.

causes such Affiliate or Third Party, as applicable, to deliver a writing to the Buyer in which it assumes all of the obligations of the Seller to the Buyer
under this Agreement, and such Affiliate or Third Party shall be deemed an assignee of Seller under this Agreement (clauses (a) and (b) the “Permitted

prior written consent, except (i) pursuant to the Permitted Assignment Provisions, (ii) pursuant to the OMERS Transaction Agreement, (iii) pursuant to the
2020 Agreement, (iv) pursuant to the Athyrium Loan Documents, or (v) pursuant to any agreement evidencing any secured Indebtedness permitted by

a Permitted Sale, from licensing any Product Rights pursuant to a Permitted License, from transferring the Marketing Approvals for any jurisdiction to a
Licensee or a Permitted Purchaser in connection with a Permitted License or Permitted Sale covering such jurisdiction, or incurring any Permitted
Indebtedness. Following the Closing, the Buyer may assign this Agreement in whole or in part to any Person, including to any Third Party, to one or more

such Person to become a party to the Intercreditor Agreement in accordance with the terms thereof or enter into an intercreditor agreement with the
administrative agent, trustee or representative under the Athyrium Credit Agreement, the “Buyer” under the OMERS Transaction Agreement and the
“Buyer” under the 2020 Agreement in form and substance substantially the same as the Intercreditor Agreement. This Agreement shall be binding upon,
inure to the benefit of and be enforceable by, the parties hereto and their respective permitted successors and assigns. Any purported assignment in
violation of this  Section 10.4 shall be null and void. Notwithstanding the foregoing, nothing in this Agreement shall prohibit Athyrium or the administrative
agent, trustee or representative under the Athyrium Credit Agreement at such time from taking any action permitted by the Intercreditor Agreement or an
Other Intercreditor Agreement, including but not limited to commencing or maintaining any Enforcement Action (as defined in the Intercreditor
Agreement) or such similar term (as defined in an Other Intercreditor Agreement) or exercising any rights with respect to its collateral under the
Bankruptcy Laws.

PARTIES REPRESENTS THAT THIS WAIVER IS KNOWINGLY, WILLINGLY, AND VOLUNTARILY GIVEN.

Section 10.10    Severability. If any term or provision of this Agreement shall for any reason be held to be invalid, illegal or

monetary damages from a Third Party in an action brought for such Third Party’s infringement of any Patent Rights relating to the Product, where such
damages, whether in the form of judgment or settlement, are awarded for such infringement of such Patent Rights but solely to the extent that such

case, except for the Excluded Payments (defined below), minus (ii) aggregate out-of-pocket expenses incurred by Seller or its Affiliates after the Closing
Date solely for the development or commercialization of the Product in the Permitted Sale Territory. For purposes of Product Partnering Revenue,
“Excluded Payments” means:

weighted average price of Seller’s common stock;

due, the amount of such debt that is forgiven, and, for accounting or Tax purposes (in accordance with GAAP), is booked as income to Seller or its
Affiliates, then such amount shall be deemed Product Partnering Revenue hereunder;

(d) loans received where the Product forms part of the security package provided for the loan for so long as an obligation of repayment exists,

provided that if at the time any such debt becomes due, the amount of such debt that is forgiven, and, for accounting or Tax purposes (in accordance with
GAAP), is booked as income to Seller or its Affiliates, then such amount shall be deemed Product Partnering Revenue hereunder;

(e) Tax credits or Tax receipts; and

(f) sales or supply of Product inventory at or below Seller’s actual cost of goods sold, provided, however that any mark-up from, or other amounts

contingent payments, upfront payments, option fees, lump-sum payments, distribution fees, joint-marketing fees, profit share, milestone payments, and

determined by agreement of the parties or by an independent appraiser mutually agreeable to the parties), assuming an arm’s length transaction made in the
ordinary course of business. To the extent that Seller makes any offsetting payments to a Permitted Purchaser (such as a true-up payment) that are
specifically permitted pursuant to the Permitted Sale (not entered into in violation of this Agreement) with such Permitted Purchaser, then the Product
Partnering Revenue under such Permitted Sale shall be calculated net of such payments. To the extent that Seller permits any Permitted Purchaser to set off
any payments payable pursuant to the Permitted Sale with such Permitted Purchaser against any amounts payable by Seller to such Permitted Purchaser,
then the Product Partnering Revenue under such Permitted Sale shall include all such payments payable to Seller under such Permitted Sale without giving
effect to any such setoff.

Participation Right, free and clear of all Liens, except for any Lien contemplated under subparts (a), (b), (f), (g), and (k) of the definition of “Permitted
Liens”. Immediately upon the sale to the Buyer by the Seller of the Revenue Participation Right pursuant to this Section 2.1, all of the Seller’s right, title
and interest in and to the Revenue Participation Right shall terminate, and all such right, title and interest shall vest in the Buyer.

(b)    It is the intention of the parties hereto that the sale, transfer, assignment and conveyance contemplated by this Agreement be, and is,

a true, complete, absolute and irrevocable sale, transfer, assignment and conveyance by the Seller to the Buyer of all of the Seller’s right, title and interest
in and to the Revenue Participation Right. Neither the Seller nor the Buyer intends the transactions contemplated by this Agreement to be, or for any
purpose characterized as, a loan from the Buyer to the Seller or a pledge, a security interest, a financing transaction or a borrowing. It is the intention of the
parties hereto that the beneficial interest in and title to the Revenue Participation Right and any “proceeds” (as such term is defined in the UCC) thereof

absolute and irrevocable sale, transfer, assignment and conveyance by the Seller to the Buyer of all of the Seller’s right, title and interest in and to the
Revenue Participation Right under applicable law, which waiver shall, to the maximum extent permitted by applicable law, be enforceable against the
Seller in any bankruptcy or insolvency proceeding relating to the Seller. Accordingly, the Seller shall treat the sale, transfer, assignment and conveyance of
the Revenue Participation Right as a sale of “accounts” or “payment intangibles” (as appropriate) in accordance with the UCC, and the Seller hereby
authorizes the Buyer to file financing statements (and continuation statements with respect to such financing statements when applicable) naming the Seller
as the debtor and the Buyer as the secured party in respect to the Revenue Participation Right. Not in derogation of the foregoing statement of the intent of
the parties hereto in this regard, and for the purposes of providing additional assurance to the Buyer in the event that, despite the intent of the parties hereto,
the sale, transfer, assignment and conveyance contemplated hereby is hereafter held not to be a sale, the Seller does hereby grant to the Buyer, as security
for the payment of amounts to the Buyer equal to the Royalty Cap less all Royalty Payments received by the Buyer pursuant to this Agreement, a security
interest in and to all right, title and interest in, to and under the Revenue Participation Right, the Royalty Payments, and the Product Collateral (collectively,
the “Back-Up Security Interest”), and the Seller does hereby authorize the Buyer, from and after the Closing, to file such financing statements (and
continuation statements with respect to such financing statements when applicable) in such manner and such jurisdictions as are necessary or appropriate to

the Buyer, unless the independent public accounting firm determines that Royalty Payments previously paid to Buyer during the period of the audit were

Seller. Any such accounting firm or Seller shall not disclose the confidential information of the Seller or any such Licensee relating to the Product to the

fully applied prior to the final quarterly Royalty Payment due hereunder, the Buyer shall promptly refund an amount equal to any such remaining
overpayment.

officers, trustees, agents and employees (the “Buyer Indemnified Parties”) from, against and in respect of all Losses suffered or incurred by the Buyer
Indemnified Parties to the extent arising out of or resulting from (i) any breach of any of the representations or warranties of the Seller in this Agreement,
and (ii) any breach of any of the covenants or agreements of the Seller in this Agreement; and

(such Buyer Indemnified Party on the one hand and such Seller Indemnified Party on the other hand being hereinafter referred to as an “Indemnified
Party”), has suffered or incurred any Losses for which indemnification may be sought under this  ARTICLE 7, the Indemnified Party shall so notify the
other party from whom indemnification is sought under this  ARTICLE 7 (the “Indemnifying Party”) promptly in writing describing such Loss, the amount
or estimated amount thereof, if known or reasonably capable of estimation, and the method of computation of such Loss, all with reasonable particularity
and containing a reference to the provisions of this Agreement in respect of which such Loss shall have occurred. If any claim, action, suit or proceeding is

Indemnifying Party is actually prejudiced thereby.

(and subject to the conditions of) this  ARTICLE 7 shall be the sole and exclusive remedy of the parties hereto and their respective Affiliates with respect to
any Losses (whether based in contract, tort or otherwise) resulting from or relating to any breach of the representations, warranties covenants and
agreements made under this Agreement or any certificate, document or instrument delivered hereunder, and each party hereto hereby waives, to the fullest
extent permitted under applicable law, and agrees not to assert after Closing, any other claim or action in respect of any such breach. Notwithstanding the
foregoing, the rights of the Buyer under the Intercreditor Agreement and claims for fraud, gross negligence, or willful misconduct shall not be waived or
limited in any way by this  ARTICLE 7.

43

SECTION 2

Representations and Warranties of the Company

Except as set forth on the Schedule of Exceptions attached hereto as Schedule I, the Company hereby represents and warrants the following as of

the date hereof:

2.1    Organization and Good Standing and Qualifications. The Company is a corporation duly organized, validly existing and in good standing

under the laws of the State of Delaware and has all requisite power and authority to own, lease, operate and occupy its properties and to carry on its
business as now being conducted. Except as set forth on the Schedule of Exceptions, the Company does not own or control, directly or indirectly, any
interest in any other corporation, partnership, trust, joint venture, limited liability company, association, or other business entity. The Company is not a
participant in any joint venture or similar arrangement. The Company is duly qualified as a foreign corporation to do business and is in good standing in
every jurisdiction in which the nature of the business conducted or property owned or leased by it makes such qualification necessary, other than those in
which the failure so to qualify or be in good standing would not have a Material Adverse Effect. For purposes of this Agreement, “Material Adverse
Effect” shall mean any event or condition that would reasonably be likely to have a material adverse effect on the business, operations, properties,
condition (financial or otherwise) or prospects of the Company and its consolidated subsidiaries (if any), taken as a whole, or adversely affect in any
material respect the ability of the Company to perform its obligations, or Investor’s rights, under the 2021 PSA.

2.2    Authorization. (i) The Company has the requisite corporate power and authority to enter into and perform its obligations under this
Agreement; (ii) the execution and delivery of this Agreement by the Company, the consummation by the Company of the transactions contemplated hereby
and thereby and the issuance, sale and delivery of the Shares have been duly authorized by all necessary corporate action and no further consent or
authorization of the Company, its Board of Directors or stockholders is required; and (iii) this Agreement has been duly executed and delivered and
constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may
be limited by applicable bankruptcy, securities, insolvency, or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and
remedies, or indemnification or by other equitable principles of general application.

2.3    Valid Issuance of Shares. The issuance of the Shares has been duly authorized by all requisite corporate action. When the Shares are issued,

sold and delivered in accordance with the terms of this Agreement for the consideration expressed herein, the Shares will be duly and validly issued and
outstanding, fully paid, and nonassessable, and will be free of all liens and restrictions on transfer other than restrictions on transfer under applicable state
and federal securities laws, and the Investor shall be entitled to all rights accorded to a holder of shares of Common Stock. The Company has reserved a
sufficient number of shares of Common Stock for issuance to the Investor in accordance with the Company’s obligations under this Agreement.

2.4    No Conflict. The execution, delivery and performance of this Agreement, and any other document or instrument contemplated hereby, by the

Company and the consummation by the Company of the transactions contemplated hereby, do not: (i) violate any provision of the certificate of
incorporation or bylaws of the Company, (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a
default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any material agreement, mortgage, deed of trust,
indenture, note, bond, license, lease agreement, instrument or obligation to which the Company is a party where such default or conflict would constitute a
Material Adverse Effect, (iii) create or impose a lien, charge or encumbrance on any property of the Company under any agreement or any commitment to
which the Company is a party or by which the Company is bound, which would constitute a Material Adverse Effect, or (iv) result in a violation of any
federal, state, local or foreign statute, rule, regulation, order, writ, judgment or decree (including federal and state securities laws and regulations)
applicable to the Company or any of its subsidiaries or by which any property or asset of the Company are bound or affected where such violation would
constitute a Material Adverse Effect. The Company is not required under federal, state or local law, rule or regulation to obtain any consent, authorization
or order of, or make any filing or registration with, any court or governmental agency in order for it to execute, deliver or perform any of its obligations
under this Agreement or issue and sell the Shares in accordance with the terms hereof (other than any filings that may be required to be made by the
Company with the Securities and Exchange Commission (the “Commission”), the National Association of Securities Dealers Automated Quotation
System (“Nasdaq”), the Nasdaq Global Select Market (the “NASDAQ Market”) or state securities commissions subsequent to the Closing); provided that,
for purposes of the representation made in this sentence, the Company is assuming and relying upon the accuracy of the relevant representations and
agreements of the Investor herein.

2

 
 
 
 
 
 
 
 
 
2.5    Consents. Except for the consents that have been obtained on or prior to the Closing or filings required to be made by the Company with
federal or state securities commissions, Nasdaq or the NASDAQ Market, no consent, approval, license, order, authorization, registration, declaration or
filing with or of any governmental entity or other person is required to be done or obtained by the Company (including, without limitation, pursuant to any
material contract to which the Company is subject or to which any of its assets, operations or management may be subject) in connection with (i) the
execution and delivery by the Company of this Agreement, (ii) the performance by the Company of its obligations under this Agreement, the
consummation by the Company of any of the transactions contemplated by this Agreement, including the issuance and sale of the Shares in accordance
with the terms hereof.

herewith will not cause the Company to be (i) in violation or default of any provision of any instrument, mortgage, deed of trust, loan, contract or
commitment, (ii) in violation of any provision of any judgment, decree, order or obligation to which it is a party or by which it or any of its properties or
assets are bound, or (iii) in violation of any federal, state or, to its knowledge, local statute, rule or governmental regulation, in the case of each of clauses
(i), (ii) and (iii), which would have a Material Adverse Effect.

2.7    Capitalization. As of October 29, 2021 (the “Reference Date”), a total of 179,936,171 shares of Common Stock were issued and
outstanding, increased thereafter solely as set forth in the next sentence. Other than in the ordinary course of business, the Company has not issued any
capital stock since the Reference Date other than pursuant to (i) employee benefit plans disclosed in the Commission Documents (as hereinafter defined),
and (ii) outstanding warrants, options or other securities disclosed in the Commission Documents. The outstanding shares of capital stock of the Company
have been duly and validly issued and are fully paid and nonassessable, were not issued in violation of any preemptive rights or similar rights to subscribe
for or purchase securities, and, for those shares issued until the Closing, have been issued in compliance with all federal and state securities laws, in each
case except as would not reasonably be expected to have a Material Adverse Effect. Except as set forth in the Commission Documents, there are no
outstanding rights (including, without limitation, preemptive rights), warrants or options to acquire, or instruments convertible into or exchangeable for,
any unissued shares of capital stock or other equity interest in the Company, or any contract, commitment, agreement, understanding or arrangement of any
kind to which the Company is a party and relating to the issuance or sale of any capital stock of the Company, any such convertible or exchangeable
securities or any such rights, warrants or options. Without limiting the foregoing, no preemptive right, co-sale right, right of first refusal, registration right,
or other similar right exists with respect to the Shares or the issuance and sale thereof. There are no shareholder agreements, voting agreements or other
similar agreements with respect to the voting or tendering of the Shares to which the Company is a party or, to the knowledge of the Company, between or
among any of the Company’s shareholders.

2.8    Commission Documents, Financial Statements. The Company’s Common Stock is registered pursuant to Section 12(b) or 12(g) of the

Securities Exchange Act of 1934, as amended (the “Exchange Act”), and during the past 12 months, the Company has timely filed all reports, schedules,
forms, statements and other documents required to be filed by it with the Commission pursuant to the reporting requirements of the Exchange Act,
including material filed pursuant to Section 13(a) or 15(d) of the Exchange Act (all of the foregoing, including filings incorporated by reference therein,
being referred to herein as the “Commission Documents”). The Company’s Common Stock is currently listed on the NASDAQ Market. The Company is
not in violation of the listing requirements of the NASDAQ Market and has no knowledge of any facts that would reasonably lead to delisting or
suspension of its Common Stock from the NASDAQ Market in the foreseeable future. As of its date, each Commission Document filed within the past 12
months complied in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission promulgated
thereunder applicable to such document, and, as of its date, after giving effect to the information disclosed and incorporated by reference therein, no such
Commission Document within the past 12 months contained any untrue statement of a material fact or omitted 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. As of their
respective dates, the financial statements of the Company included in the Commission Documents filed with the Commission during the past 12 months
complied as to form and substance in all material respects with applicable accounting requirements and the published rules and regulations of the
Commission or other applicable rules and regulations with respect thereto. Such financial statements 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 financial statements, to the extent they may not include footnotes or may be condensed or summary statements), and fairly
present in all material respects the financial position of the Company 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).

4

 
 
 
2.9    Internal Controls and Procedures. The Company maintains disclosure controls and procedures as such terms are defined in, and required

by, Rule 13a-15 and Rule 15d-15 under the Exchange Act. Such disclosure controls and procedures are effective as of the latest date of management’s
evaluation of such disclosure controls and procedures as set forth in the Commission Documents to ensure that all material information required to be
disclosed by the Company in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time
periods specified in the rules and forms of the Commission. The Company maintains a system of internal controls over financial reporting sufficient to
provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; and (ii) transactions are
recorded as necessary to permit preparation of financial statements in conformity with GAAP.

or have occurred that would, individually or in the aggregate, have a Material Adverse Effect on the Company.

2.11    No Undisclosed Liabilities. Neither the Company nor any of its subsidiaries has any liabilities, obligations, claims or losses (whether

liquidated or unliquidated, secured or unsecured, absolute, accrued, contingent or otherwise) that would be required to be disclosed on a balance sheet of
the Company or any of its subsidiaries (including the notes thereto) in conformity with GAAP and are not disclosed in the Commission Documents, other
than those incurred in the ordinary course of the Company’s or its subsidiaries’ respective businesses since September 30, 2021.

2.12    No Undisclosed Events or Circumstances. Except for the transactions contemplated by this Agreement and the 2021 PSA, no event or

circumstance has occurred or exists with respect to the Company, its subsidiaries, or their respective businesses, properties, operations or financial
condition, which, under applicable law, rule or regulation, requires public disclosure or announcement by the Company but which has not been so publicly
announced or disclosed and which, individually or in the aggregate, would have a Material Adverse Effect on the Company.

2.13    Actions Pending. There is no action, suit, claim, investigation or proceeding pending or, to the knowledge of the Company, threatened

against the Company or any subsidiary which questions the validity of this Agreement or the transactions contemplated hereby or any action taken or to be
taken pursuant hereto. Except as set forth in the Commission Documents, there is no action, suit, claim, investigation or proceeding pending or, to the
knowledge of the Company, threatened, against or involving the Company, any subsidiary, or any of their respective properties or assets that could be
reasonably expected to have a Material Adverse Effect on the Company. Except as set forth in the Commission Documents, no judgment, order, writ,
injunction or decree or award has been issued by or, to the knowledge of the Company, requested of any court, arbitrator or governmental agency which
could be reasonably expected to result in a Material Adverse Effect.

2.14    Compliance with Law. The businesses of the Company and its subsidiaries have been and are presently being conducted in accordance with
all applicable federal, state and local governmental laws, rules, regulations and ordinances, except as would not reasonably be expected to cause a Material
Adverse Effect. The Company and each of its subsidiaries have all franchises, permits, licenses, consents and other governmental or regulatory
authorizations and approvals necessary for the conduct of its business as now being conducted by it, except for such franchises, permits, licenses, consents
and other governmental or regulatory authorizations and approvals, the failure to possess which, individually or in the aggregate, could not reasonably be

promulgated pursuant to the Act (“Regulation D”) and/or any other applicable federal and state securities laws. The sale and issuance of the Shares
pursuant to, and the Company’s performance of its obligations under, this Agreement will not (i) result in the creation or imposition of any liens, charges,
claims or other encumbrances upon the Shares or any of the assets of the Company, or (ii) entitle the holders of any outstanding shares of capital stock of
the Company to preemptive or other rights to subscribe to or acquire the Shares or other securities of the Company.

2.16    Transfer Taxes. All stock transfer or other taxes (other than income taxes) which are required to be paid in connection with the sale and

Investor Indemnified Parties to the extent arising out of, or resulting from, (i) any breach of any of the representations or warranties of the Company in this
Agreement; and (ii) any breach of any covenant or undertaking of the Company in this Agreement.

(b) The Investor agrees to indemnify, defend and hold harmless the Company and its Affiliates and its and their directors, officers,
agents and employees (the “Company Indemnified Parties”) from, against and in respect of all Losses suffered or incurred by the Company Indemnified
Parties to the extent arising out of, or resulting from, (i) any breach of any of the representations or warranties of the Investor in this Agreement; and (ii)
any breach of any covenant or undertaking of the Investor in this Agreement.

7.2    Notice of Claims. If an event or omission (including, without limitation, any claim asserted or action or proceeding commenced by a third

party) occurs which either an Investor Indemnified Party, on the one hand, or a Company Indemnified Party, on the other hand (such Investor Indemnified
Party on the one hand and such Company Indemnified Party on the other hand hereinafter referred to as an “Indemnified Party”), has suffered any Loss
for which indemnification may be asserted pursuant to this Section 7, the Indemnified Party shall so notify the other party from whom indemnification is
sought under this Section 7 (the “Indemnifying Party”) promptly in writing, setting forth the Loss, the amount or estimated amount thereof, if known or
reasonably capable of estimation, and the method of computation of such Loss, all with reasonable particularity containing a reference to the provisions of
this Agreement in respect of which such Loss shall have occurred. If any claim, action, suit or proceeding is asserted or instituted by or against a third party
with respect to which an Indemnified Party intends to claim any Losses under this Section 7, such Indemnified Party shall promptly notify the
Indemnifying Party in writing of such claim, action, suit or proceeding. Such notice will be a condition precedent to any obligation of the Indemnifying
Party to act under this Agreement but will not relieve it of its obligations under the indemnity except to the extent that the failure to provide prompt written
notice as provided in this Agreement actually prejudices the Indemnifying Party with respect to the transactions contemplated by this Agreement and to the
defense of the liability.

7.3    Limitations on Liability. Except in cases of fraud, gross negligence, or willful misconduct, no party hereto shall be liable for any
consequential, punitive, special or incidental damages under this  Section 7 (and no claim for indemnification hereunder shall be asserted) as a result of any
breach or violation of any covenant or agreement of such party (including under this  Section 7) in or pursuant to this Agreement.

7.4    Exclusive Remedy. Except as set forth herein or in the 2021 PSA, from and after Closing, the rights of the parties hereto pursuant to (and
subject to the conditions of) this  Section 7 shall be the sole and exclusive remedy of the parties hereto and their respective Affiliates with respect to any
Losses (whether based in contract, tort or otherwise) resulting from or relating to any breach of the representations, warranties covenants and agreements
made under this Agreement or any certificate, document or instrument delivered hereunder, and each party hereto hereby waives, to the fullest extent
permitted under applicable law, and agrees not to assert after Closing, any other claim or action in respect of any such breach. Notwithstanding the
foregoing, claims for fraud, gross negligence, or willful misconduct shall not be waived or limited in any way by this  Section 7.
