SUMMARY RISK FACTORS

Our  business  is  subject  to  a  number  of  risks  of  which  you  should  be  aware  before  making  an  investment  decision.  The  risks  described
below are a summary of the principal risks associated with an investment in us and are not the only risks we face. You should carefully consider
these risks, the risk factors in Item IA, and the other reports and documents that we have filed with the Securities and Exchange Commission (SEC).

Risks Related to the Development and Commercialization of U2 and UKONIQ (umbralisib)
● We face substantial uncertainty regarding whether the U.S. Food and Drug Administration (FDA) will approve U2 and whether we will be able
to maintain approval of UKONIQ in its currently marketed indications in light of the FDA’s plan to hold an ODAC meeting in March or April
2022  to  discuss  the  benefit-risk  of  U2  in  CLL  and  SLL  and  the  benefit  risk  of  UKONIQ  in  R/R  FL  and  MZL.  If  we  are  unable  to  obtain
regulatory approval for U2 or if we are unable to maintain current approvals of UKONIQ, our business will be materially harmed. Even if the
FDA approves U2, our ability to successfully commercialize and generate revenue from UKONIQ and U2 may be adversely impacted by the
recent regulatory developments.
In January 2022, the FDA placed selected Company clinical trials, investigating U2 and UKONIQ in CLL and NHL, on a partial clinical hold in
light of concerns about the benefit-risk profile. Our business will be adversely affected if the clinical hold cannot be favorably resolved in a
timely manner or if such regulatory concerns lead to more burdensome clinical or preclinical studies that cause significant delay or expense in
the research or development of U2 or UKONIQ.

●

Risks Related to Commercialization
● We have limited experience as a commercial company, and the marketing and sale of UKONIQ or any future approved products, including U2

●

●

●

in CLL and ublituximab in RMS, may be less successful than anticipated.
The COVID-19 pandemic and related response measures to control it have impacted our sales and marketing efforts for UKONIQ and could
have an adverse impact on our commercial launch of ublituximab, if approved.
If UKONIQ or, if approved, U2 in CLL or ublituximab in RMS do not achieve broad market acceptance among physicians, patients, payors, and
the medical community, the revenues that we generate from product sales will be limited.
If the market opportunities for UKONIQ and future products for which we may receive approval, including U2 in CLL or ublituximab in RMS,
are smaller than we estimate or if any approval that we obtain is based on a narrower patient population or the labeling includes warnings or
limitations that are not acceptable to patients or healthcare providers, our revenue will be adversely affected.

● We  face  substantial  competition  for  treatments  for  our  target  indications,  which  may  result  in  others  commercializing  drugs  before  or  more

successfully than we do, resulting in the reduction or elimination of our commercial opportunity.
If we are unable to establish additional commercial capabilities and infrastructure to support a potential launch in CLL or RMS or expansion
into geographies outside the U.S., we may be unable to generate sufficient revenue to sustain our business.
Product liability lawsuits could cause us to incur substantial liabilities and limit product commercialization.

●

●

Risks Related to our Financial Position and Need for Additional Capital
● We have incurred significant operating losses since our inception and anticipate that we will continue to incur losses for the foreseeable future.
● We  will  need  to  raise  substantial  additional  funding.  If  we  are  unable  to  raise  capital  when  needed,  we  will  be  forced  to  delay,  reduce,  or

eliminate some of our drug development programs or commercialization efforts.

● Our level of indebtedness and debt service obligations could adversely affect our financial condition and may make it more difficult for us to

fund our operations.

Risks Related to Drug Development and Regulatory Approval
●

If  we  are  unable  to  obtain  regulatory  approval  for  our  product  candidates  and  ultimately  cannot  commercialize  one  or  more  of  them,  or
experience significant delays in doing so, our business will be materially harmed.

● Our products and product candidates may cause undesirable side effects that could delay or prevent their regulatory approval or significantly

limit their commercial profile following marketing approval, if any.

● Because results of preclinical studies and early clinical trials are not necessarily predictive of future results, any product candidate we advance
may  not  have  favorable  results  in  later  clinical  trials.  Moreover,  interim,  “top-line,”  and  preliminary  data  from  our  clinical  trials  that  we
announce or publish may change, or the perceived product profile may be impacted, as more patient data or additional endpoints are analyzed.
● Any  product  candidates  we  may  advance  through  clinical  development  are  subject  to  extensive  regulation,  which  can  be  costly  and  time
consuming, cause unanticipated delays, or prevent the receipt of the required approvals. Although we have received orphan drug designation for
UKONIQ  and  for  some  of  our  drug  candidates  for  specified  indications  and  may  seek  additional  orphan  drug  designations,  we  may  be
unsuccessful in obtaining or maintaining the benefits associated with orphan drug status.

Table of Contents

Risks Related to Governmental Regulation of the Pharmaceutical Industry
● We are subject to extensive regulation, including new legislative and regulatory proposals, that may increase our compliance costs and adversely

●
●

affect our ability to market our products, obtain collaborators and raise capital.
If we fail to comply with various healthcare laws and regulations, we may incur losses or be subject to liability.
If  we  fail  to  comply  with  regulatory  requirements,  any  product  for  which  we  obtain  marketing  approval  could  be  subject  to  restrictions  or
withdrawal from the market and we may be subject to penalties.

Risks Related to our Dependence on Third Parties
●

If  the  third  parties  on  which  we  rely  to  conduct  our  clinical  trials  and  generate  clinical,  preclinical  and  other  data  necessary  to  support  our
regulatory applications do not perform their services as required, we may not be able to obtain regulatory approval for or commercialize our
product candidates when expected or at all.

● Our reliance on third parties for commercial and clinical supply of our products and product candidates increases the risk that we will not have
sufficient  quantities  of  our  products  or  product  candidates  or  such  quantities  at  an  acceptable  cost  or  quality,  which  could  delay,  prevent  or
impair our development or commercialization efforts.

● Because we have in-licensed our products and product candidates from third parties, any dispute with or non-performance by our licensors will

adversely affect our ability to develop and commercialize the applicable product.

Risks Related to Intellectual Property
● Our success depends upon our ability to obtain and protect our intellectual property, and if the scope of our patent protection obtained is not
sufficiently  broad,  our  competitors  could  develop  and  commercialize  products  similar  or  identical  to  ours,  and  our  ability  to  successfully
commercialize our products may be impaired.

● Our  patent  protection  could  be  reduced  or  eliminated  for  non-compliance  with  various  procedural  and  other  requirements  imposed  by

governmental patent agencies.

● We  may  need  to  license  certain  intellectual  property  from  third  parties,  and  such  licenses  may  not  be  available  or  may  not  be  available  on

commercially reasonable terms.
If we or our partners are sued for infringing intellectual property rights of third parties, it will be costly and time consuming, and an unfavorable
outcome in that litigation would have a material adverse effect on our business.
If we are unable to protect the confidentiality of our trade secrets, our business may be significantly harmed.

●

●

Risks Related to COVID-19
●

●

Public health issues, and specifically the pandemic caused by COVID-19, could have an adverse impact on our financial condition and results of
operations and other aspects of our business.
Patients and healthcare providers have raised concerns that immunosuppressive products, like anti-CD20 antibodies and other B-cell targeted
agents,  may  increase  the  risk  of  acquiring  COVID-19  or  lead  to  more  severe  complications  upon  infection.  These  concerns  may  impact  the
commercial potential for ublituximab and other immunosuppressive products that we have in development.

General Risks Related to Our Business Organization and Governance, Strategy, Employees and Growth Management

● We will need to develop and expand our business, and we may encounter difficulties in managing this development and expansion.
● Our  ability  to  continue  our  clinical  development  and  commercialization  activities  will  depend  on  our  ability  to  attract  and  maintain  key

management and other personnel.

● Certain of our executive officers, directors and other stockholders own more than 5% of our outstanding common stock and may be able to

influence our management and the outcome of matters submitted to shareholders for approval.

● Certain anti-takeover provisions in our charter documents and Delaware law could make a third-party acquisition more difficult, which could

limit the price investors might be willing to pay for our common stock.

● Our  stock  price  is,  and  we  expect  it  to  remain,  volatile,  which  could  limit  investors’  ability  to  sell  stock  at  a  profit  and  could  subject  us  to

securities and shareholder derivative litigation.

The foregoing is only a summary of some of our risks. These and other risks are discussed more fully in the section entitled “Risk Factors”

in Part II, Item IA and elsewhere in this Annual Report on Form 10-K (our Risk Factors).

ITEM 1. BUSINESS.

OVERVIEW

TG Therapeutics is a fully-integrated, commercial stage biopharmaceutical company focused on the acquisition, development and
commercialization of novel treatments for B-cell malignancies and autoimmune diseases. In addition to an active research pipeline including
five  investigational  medicines  across  these  therapeutic  areas,  we  have  received  accelerated  approval  from  the  U.S.  Food  and  Drug
Administration (FDA) for UKONIQ® (umbralisib), for the treatment of adult patients with relapsed or refractory marginal zone lymphoma
who  have  received  at  least  one  prior  anti-CD20-based  regimen  and  relapsed  or  refractory  follicular  lymphoma  who  have  received  at  least
three prior lines of systemic therapies. Currently, we have three programs in Phase 3 development for the treatment of patients with relapsing
forms of multiple sclerosis (RMS) and patients with chronic lymphocytic leukemia (CLL) and several investigational medicines in Phase 1
clinical  development.  We  also  actively  evaluate  complementary  products,  technologies  and  companies  for  in-licensing,  partnership,
acquisition and/or investment opportunities.

FDA Accelerated Approval and U.S. Launch of UKONIQ

On February 5, 2021, we announced that the FDA granted accelerated approval of umbralisib, now referred to as UKONIQ, for the
treatment  of  adult  patients  with  relapsed  or  refractory  Marginal  Zone  Lymphoma  (MZL)  who  have  received  at  least  one  prior  anti-CD20
based  regimen  and  adult  patients  with  relapsed  or  refractory  Follicular  Lymphoma  (FL)  who  have  received  at  least  three  prior  lines  of
systemic  therapy.  UKONIQ  is  the  first  and  only,  oral,  once  daily,  inhibitor  of  phosphoinositide  3  kinase  (PI3K)  delta  and  casein  kinase
1  (CK1)  epsilon.  Accelerated  approval  was  granted  for  these  indications  based  on  overall  response  rate  (ORR)  data  from  the  Phase  2b
UNITY-NHL Trial (NCT02793583). Continued approval for these indications may be contingent upon verification and description of clinical
benefit in a confirmatory trial. 

Following  FDA  approval,  we  launched  UKONIQ,  making  it  available  to  patients  through  a  distribution  network  that  includes  a
specialty pharmacy and specialty distributors. Payor coverage of UKONIQ and inclusion in the NCCN guidelines have been consistent with
the FDA-approved indications. We are committed to helping patients access their prescription for UKONIQ through the TG Patient Support
Program, which we launched following the approval of UKONIQ.

Regulatory Developments related to UKONIQ in Combination with Ublituximab (U2) in CLL and UKONIQ in R/R MZL and FL

In  March  2021,  we  submitted  a  Biologics  License  Application  (BLA)  for  ublituximab  in  combination  with  UKONIQ  for  the
treatment  of  adult  patients  with  chronic  lymphocytic  leukemia  (CLL)  or  small  lymphocytic  lymphoma  (SLL)  based  on  the  results  of  the
UNITY-CLL Phase 3 study. In May 2021, we submitted a supplemental New Drug Application (sNDA) for UKONIQ to add an indication for
CLL  and  SLL  in  combination  with  ublituximab.  Both  the  BLA  and  sNDA  for  U2  in  CLL  and  SLL  were  accepted  for  filing,  with  a
Prescription Drug User Fee Act (PDUFA) goal date of March 25, 2022 for both applications.

In  November  2021,  we  received  notification  from  the  FDA  that  it  planned  to  host  a  meeting  of  the  Oncologic  Drugs  Advisory
Committee (ODAC) in connection with its review of the pending BLA/sNDA for U2 for the treatment of adult patients with CLL and SLL.
The  FDA’s  concern  giving  rise  to  the  ODAC  meeting  stems  from  an  early  analysis  of  overall  survival  from  the  UNITY-CLL  trial,  which
showed  a  possible  increased  risk  of  death  in  patients  receiving  U2  compared  to  the  control  arm  of  obinutuzumab  plus  chlorambucil.  The
potential questions and discussion topics for the ODAC include: the benefit-risk of the U2 combination for the treatment of CLL or SLL,
including the preliminary OS analysis, rates of serious adverse events, rates of dose discontinuations due to adverse events, and rates of dose
modifications from the UNITY-CLL trial, and the benefit-risk of UKONIQ for R/R MZL and FL, each of which has been raised as a concern
by the FDA.

Table of Contents

Due  to  the  concerns  that  prompted  the  ODAC  meeting,  the  FDA  also  placed  select  clinical  trials  investigating  U2  and  its
components in CLL and NHL, on partial clinical hold in January 2022. Most studies included in the partial clinical hold were already closed
to new enrollment or were on had been placed on administrative hold to new enrollment by the Company prior to the time the FDA imposed
the partial clinical hold.

Registration Directed Clinical Trial Updates:

In 2021, we continued to advance our late-stage pipeline in hematology and multiple sclerosis. The below are recent updates from 

our current registration directed clinical trials.  Currently clinical trials enrolling CLL or NHL patients to U2 or its components are on partial 
clinical hold.

Hematology:  

● UNITY-NHL Phase 2b Trial: UNITY-NHL is a broad, multicenter, open-label, Phase 2b registration-directed clinical trial

designed to evaluate the efficacy and safety of UKONIQ monotherapy and UKONIQ plus ublituximab (U2) combinations in
patients with previously treated non-Hodgkin’s lymphoma (NHL).

o

In December 2021, TG presented data from the UNITY-NHL trial during the American Society of Hematology
(ASH) 2021 annual meeting which included updates from the U2 cohort in patients with relapsed or refractory
MZL and an update from the U2 plus bendamustine cohort in relapsed or refractory Diffuse Large B-cell
Lymphoma (DLBCL).

● UNITY-CLL Phase 3 Trial Evaluating Umbralisib plus Ublituximab (U2): UNITY-CLL is a global, multi-center, Phase 3,
randomized,  controlled  clinical  trial  comparing  the  U2  combination  to  an  active  control  arm  of  obinutuzumab  plus
chlorambucil  in  patients  with  both  treatment  naive  and  relapsed  or  refractory  CLL.  The  primary  endpoint  for  this  study  is
progression free survival (PFS).

o The UNITY-CLL trial met its primary endpoint, demonstrating that U2 significantly improved PFS over

obinutuzumab plus chlorambucil (HR=0.54, p<0.0001) as well as ORR (p<0.001) in patients with CLL; with
consistent PFS improvement across subgroups, including treatment naïve CLL (HR=0.48) and relapsed/refractory
CLL (HR=0.60). These data, as well as additional sub-analyses from the UNITY-CLL trial were presented at
major medical meetings in 2021.

● ULTRA-V Phase 2/3 Trial Evaluating U2 plus Venetoclax in CLL: The ULTRA-V study is being conducted in two parts.
The ULTRA-V Phase 2 trial is designed to investigate the efficacy and safety of U2 in combination with venetoclax in subjects
with treatment-naïve CLL and relapsed or refractory CLL, while the Phase 3 trial will compare U2 vs U2 plus venetoclax in the
same population.

o The  Phase  2  portion  completed  enrollment  of  approximately  165  patients  in  early  2021.  The  Phase  3  portion

commenced at approximately the same time.

Multiple Sclerosis:  

● ULTIMATE  I  &  II  Trials  Evaluating  Single  Agent  Ublituximab  in  RMS:  ULTIMATE  I  and  ULTIMATE  II  are  two
independent Phase 3 trials. Each trial is a global, randomized, multi-center, double-blinded, double-dummy, active-controlled
study comparing the efficacy and safety/tolerability of ublituximab (450mg dose administered by one hour intravenous infusion
every  6  months,  following  a  Day  1  infusion  of  150mg  over  four  hours,  and  a  Day  15  infusion  of  450mg  over  one  hour)  to
teriflunomide (14mg oral tablets taken once daily) in subjects with relapsing forms of Multiple Sclerosis (RMS).

o

In April 2021, data from the ULTIMATE I & II trials were presented for the first time at the American Academy
of Neurology Annual meeting. Both studies met their primary endpoint with ublituximab treatment demonstrating
a statistically significant reduction in annualized relapse rate (ARR) over a 96-week period

6

Table of Contents

(p<0.005 in each trial). Key secondary MRI endpoints were also met. Additional data from these trials has been
presented at various other medical meetings.

o On December 14, 2021, we announced that the FDA accepted a BLA for ublituximab as a treatment for patients
with  RMS.  The  FDA  set  a  PDUFA  goal  date  of  September  28,  2022  and  notified  the  Company  that  it  is  not
currently planning to hold an advisory committee meeting to discuss this application.

As a fully-integrated, commercial stage biopharmaceutical company focused on the acquisition, development and commercialization

of novel treatments for B-cell malignancies and autoimmune diseases, our key corporate objectives include:

● Successfully commercializing UKONIQ in the U.S. for relapsed or refractory MZL and FL;
● Obtaining FDA approval for U2 in CLL and SLL, and ublituximab in RMS;
● Preparing for additional commercial launches and scaling commercialization capabilities to ensure, if approved, broad access to

patients for the approved indications for umbralisib and ublituximab;

● Developing U2 in NHL as well as in combination with other novel agents for CLL;
● Advancing  cosibelimab  (TG-1501),  TG-1701,  and  TG-1801  through  clinical  development  and  defining  potential  regulatory

paths for these drug candidates either as single agents and in combination with umbralisib, ublituximab, and/or U2;

● Building upon the MS clinical program to develop ublituximab in additional MS indications and other autoimmune diseases;
● Continuing to expand our pipeline with mechanisms of importance to B-cell mediated diseases;
● Evaluating potential strategic collaborations to maximize the value of our programs and B-cell directed platform; and
● Maintaining our “patient first” culture as we grow our business.

Our Approach and Platform

Our  approach  to  drug  development  is  centered  on  developing  solutions  for  patients  rather  than  developing  single  therapies  for  a
disease. Our process begins by identifying validated targets against B-cell diseases, and then searching for and, ideally, acquiring what we
believe  to  be  “best-in-class”  compounds  with  complementary  mechanisms  against  these  targets,  with  the  goal  of  developing  multi-drug
proprietary targeted combinations, which can potentially offer new treatment options for patients in need.

Our  preference  is  to  identify  targets  for  which  there  is  human  clinical  proof  of  concept  that  the  mechanism  is  active  in  B-cell
diseases  and  then  to  identify  drug  candidates  that  effectively  modulate  the  desired  molecular  target.  We  identify  these  drug  candidates  at
academic centers of excellence or in development at biotech companies or pharmaceutical companies globally. Our current drug candidates
were  acquired  through  license  agreements,  collaborations,  or  joint  ventures  with  biopharmaceutical  companies  located  in  the  US,  France,
Switzerland, India, and China. This approach enables us to minimize target risk while looking for the best available drug candidates around
the world. By focusing on B-cell diseases and targets with a known activity profile, we believe that we can quickly identify the patients

most likely to respond, resulting in a more efficient development path with the potential for a greater likelihood of success. Importantly, since
our drug candidates have complementary mechanisms of action, we can rapidly explore combination therapies, which we believe is essential
to improving outcomes for patients and may hold the key to potentially identifying cures for patients with B-cell diseases.

Our approach is enabled by our clinical development platform which includes:

● An internal team with a deep understanding of B-cell diseases and significant experience successfully pioneering innovative

treatments for these complex diseases; and

● A vast external network of more than 350 community and academic clinical trial sites with significant experience researching

B-cell diseases.

B-CELL DISEASES OVERVIEW

The constellation of diseases that arise from abnormally growing or behaving B-cells is substantial. One group of diseases related to
abnormal  B-cell  growth  is  malignant  lymphomas,  including  NHL  and  CLL.  There  are  over  80  types  of  NHL,  approximately  40  to  50  of
which are due to malignant B-cells. These diseases can include some of the slowest and fastest growing cancers known to medicine. Some of
the more common B-cell malignancies include MZL, FL, SLL and CLL.

The other major group of diseases caused by abnormally functioning B-cells is autoimmune disorders. These diseases may result from
inappropriate  production  of  antibodies  from  the  B-cells.  These  antibodies  cannot  discriminate  “self”  from  “non-self,”  and  inadvertently
mount  a  disabling  immune  response  against  normal  organs.  Examples  of  common  and  very  debilitating  autoimmune  disorders  for  which
abnormally functioning B-cells have been implicated include MS and rheumatoid arthritis (RA). 

The Company’s current clinical programs are focused on MZL, FL, CLL and MS.

Marginal Zone Lymphoma Overview

MZL comprises a group of indolent (slow growing) mature B-cell non-Hodgkin lymphomas (NHLs). MZL is generally considered a
chronic and incurable disease. MZL is the second most common form of indolent NHL and accounts for approximately 10.6% of all NHL
cases. More than 8000 new cases of MZL are expected in the US in 2021, with approximately 6000 patients with R/R MZL on therapy each
year.  MZL  consists  of  three  different  subtypes:  extranodal  MZL  of  the  mucosal-associated  lymphoid  tissue  (MALT),  nodal  marginal  zone
lymphoma (NMZL), and splenic marginal zone lymphoma (SMZL).

Follicular Lymphoma Overview

FL is typically an indolent form of NHL that arises from B-lymphocytes. It is the most common form of NHL. FL is generally not
curable and is considered a chronic disease, as patients can live for many years with this form of lymphoma. FL accounts for approximately
17.1% of all NHL cases. More than 13,000 new cases of FL are expected in the US in 2021, with ~12,500 patients with relapsed/refractory
(R/R) FL on therapy each year.

Chronic Lymphocytic Leukemia Overview

Chronic lymphocytic leukemia (CLL) is the most common type of adult leukemia in the US. It is projected to represent 11% of all
newly diagnosed hematological malignancies. About 195,000 Americans are living with CLL, and the prevalence is predicted to rise due to
an aging population, high survival rates, and improved outcomes with novel treatments. The incidence of CLL has also increased in the last
20 years and is disproportionately affecting the elderly. It is estimated that there will be 21,250 new cases in 2021.

Multiple Sclerosis Overview

Relapsing  multiple  sclerosis  (RMS)  is  a  chronic  demyelinating  disease  of  the  central  nervous  system  (CNS)  and  includes  people
with  relapsing-remitting  multiple  sclerosis  (RRMS)  and  people  with  secondary  progressive  multiple  sclerosis  (SPMS)  who  continue  to
experience relapses. RRMS is the most common form of multiple sclerosis (MS) and is characterized by episodes of new or worsening signs
or symptoms (relapses) followed by periods of recovery. MS is the most prevalent chronic inflammatory disease of the CNS. It is estimated
that nearly 1 million people are living with MS in the United States and over 2.3 million people world-wide are living with MS.

OUR PRODUCTS UNDER DEVELOPMENT

We have leveraged our B-cell platform to develop a robust drug pipeline of both targeted orally available, potent and selective small
molecule kinase inhibitors and intravenously delivered “off-the-shelf” immunotherapies that leverage the patient’s own immune system to
fight cancer. We currently license worldwide development and commercial rights, subject to certain limited geographical restrictions, for all
of  our  pre-clinical  and  clinical  programs.  The  following  table  summarizes  the  current  clinical  trial  status  for  our  most  advanced  drug
candidates as of February 2022.

Ublituximab Overview

Ublituximab is an investigational glycoengineered monoclonal antibody that targets a unique epitope on CD20-expressing B-cells.
When  ublituximab  binds  to  the  B-cell  it  triggers  a  series  of  immunological  reactions  including  antibody-dependent  cellular  cytotoxicity
(ADCC) and complement dependent cytotoxicity (CDC), leading to destruction of the cell. Additionally, ublituximab is uniquely designed to
lack certain sugar molecules normally expressed on the antibody. Removal of these sugar molecules, a process called glycoengineering, has
been shown to enhance the potency of ublituximab, especially the ADCC activity.

Targeting  CD20  using  monoclonal  antibodies  has  proven  to  be  an  important  therapeutic  approach  for  the  management  of  B-cell

malignancies and autoimmune disorders, both diseases driven by the abnormal growth or function of B-cells.

Ublituximab is being evaluated in pivotal and early phase clinical trials for patients with NHL, CLL, and RMS.

Umbralisib - UKONIQ Overview

Umbralisib is an oral inhibitor of PI3K-delta and CK1-epsilon administered once daily. The phosphoinositide-3-kinases (PI3Ks) are
a family of enzymes involved in many important cellular functions, including cell proliferation and survival, cell differentiation, intracellular
trafficking, and immunity.

There are 4 isoforms of PI3K (alpha, beta, delta, and gamma), of which the delta isoform is highly expressed in hematopoietic cells
and malignant lymphoid diseases. The PI3K pathway is among one of the most commonly mutated pathways across all of cancer biology.
Umbralisib is highly selective for the delta isoform of PI3K and has limited to no impact on the other PI3K isoforms. Umbralisib also inhibits
casein  kinase  1  epsilon  (CK1-epsilon).  CK1-epsilon  is  a  major  regulator  of  oncoprotein  translation,  which  drives  growth  and  survival  of
lymphoma cells, including c-Myc. A manuscript titled, "Silencing c-Myc Translation as a Therapeutic Strategy through Targeting PI3K Delta
and CK1 Epsilon in Hematological Malignancies," was published in the First Edition section of Blood, the Journal of the American Society
of  Hematology.  Importantly,  the  manuscript  for  the  first  time  reported  on  umbralisib’s  unique  complimentary  mechanism  of  inhibiting  the
protein kinase casein kinase-1 epsilon (CK1e), which may lead to a differentiated safety profile by supporting T regulatory cells, a part of the
immune system necessary to protect against autoimmune mediated toxicities.

In February 2021, we obtained accelerated approval of UKONIQ by the FDA for the treatment of adult patients with relapsed or
refractory  MZL  who  have  received  at  least  1  prior  anti-CD20-based  regimen  and  adult  patients  with  relapsed  or  refractory  FL  who  have
received at least 3 prior lines of systemic therapy. Both indications were approved based on overall response rate observed in the UNITY-
NHL trial. Continued approval for these indications may be contingent upon verification and description of clinical benefit in a confirmatory
trial.  Shortly after receiving approval, we initiated our commercial launch of UKONIQ in the United States. We have staffed, trained and
prepared a commercialization team comprising a field force of sales representatives and medical affairs professionals with deep experience in
hematology.

Current Phase 3 or Registration-Directed Clinical Trials for Ublituximab and Umbralisib:

The below are the current Phase 3 trials and registration-directed clinical trials of umbralisib and ublituximab. Select CLL and NHL

trials are currently on partial clinical hold. (See discussion of UNITY-CLL below for more information on the partial clinical hold).

UNITY-NHL Phase 2b Trial: UNITY-NHL is a broad, multicenter, open-label, Phase 2b registration-directed clinical trial designed

to evaluate the efficacy and safety of umbralisib monotherapy and U2 combinations in patients with previously treated NHL.

● UNITY-NHL MZL Single Agent Umbralisib Cohort: The MZL cohort enrolled adult patients who had at least one prior line
of therapy that included an anti-CD20 monoclonal antibody. This cohort was designed to evaluate the safety and efficacy of
single  agent  umbralisib  and  the  primary  endpoint  was  ORR  as  determined  by  Independent  Review  Committee  (IRC)
assessment. Secondary endpoints included safety, duration of response, and progression-free survival (PFS). 

 In April 2019, the FDA granted orphan drug designation to umbralisib for the treatment of patients with any of the three types
of marginal zone lymphoma (MZL): nodal, extranodal, and splenic MZL.

In  March  2021,  results  from  the  UNITY-NHL  Phase  2b  trial  were  published  in  the  Journal  of  Clinical  Oncology  The  results
from the MZL single agent cohort supported the FDA approval of UKONIQ in this indication.

● UNITY-NHL FL/SLL Single Agent Umbralisib Cohort: The FL/SLL cohort enrolled adult patients who had two or more
prior lines of therapy that included an anti-CD20 monoclonal antibody and an alkylating agent. In October 2019, we announced
that  the  FL  patients  within  this  cohort  met  the  primary  endpoint  of  ORR  as  determined  by  Independent  Review  Committee
(IRC)  for  all  treated  follicular  lymphoma  patients  (n=118).  In  March  2020,  the  FDA  granted  orphan  drug  designation  to
umbralisib, for the treatment of patients with FL. As noted above, in March 2021, results from the UNITY-NHL Phase 2b trial
were published in the Journal of Clinical Oncology. The results from the FL single agent cohort supported the FDA approval of
UKONIQ in this indication.

● UNITY-NHL Additional Cohorts: There are additional exploratory cohorts of the UNITY-NHL trial.

● At ASH 2021, we presented data from a cohort of relapsed or refractory (R/R) MZL patients who were treated
with the U2 combination. A total of 72 R/R MZL patients were enrolled. Patients had a median of 2 prior lines of therapy (range
1 - 9), with 25% refractory to their immediate prior therapy. Overall Response Rate (ORR) by independent review committee
(IRC)  was  70%,  with  21%  complete  response  (CR)  rate  (n=71).  Median  duration  of  response  (DOR)  was  not  reached  at  a
median  follow  up  of  20  months.  Grade  3/4  AEs  of  clinical  interest  included  diarrhea  (13%),  neutropenia  (18%),  ALT/AST
increased (15%) and non-infectious colitis (2.8%).

● At ASH 2021, we also presented data from a cohort of R/R diffuse large B-cell lymphoma (DLBCL). A total of
226  patients  were  treated  within  this  cohort,  30  patients  received  umbralisib  monotherapy,  66  patients  received  U2,  and  130
patients  received  U2  plus  bendamustine.  IRC  assessed  response  rates  included:  43%  ORR  and  17%  CR  for  U2  plus
bendamustine triple combination (n=130); 32% ORR and 11% CR for U2 double combination (n=66); 13% ORR and 3% CR
for  umbralisib  monotherapy  (n=30).  IRC  assessed  median  duration  of  response  (DOR)  was  3  months  for  umbralisib
monotherapy,  28  months  for  U2  combination,  and  8  months  for  U2  plus  bendamustine.  Both  U2  and  U2  +  bendamustine
demonstrated  a  manageable  safety  profile.  Grade  3/4  AEs  of  special  interest  occurring  in  the  U2  group  (n=66)  included
ALT/AST increased (12%), non-infectious colitis (2%), diarrhea (2%), neutropenia (11%) and pneumonitis (2%). Grade 3/4

Table of Contents

AEs of special interest occurring in the U2 plus bendamustine group (n=130) included ALT/AST increased (5%), non-infectious
colitis (2%), diarrhea (7%), neutropenia (27%), pneumonitis (1%) and rash (2%).

UNITY-CLL  Phase  3  Trial  Evaluating  Umbralisib  plus  Ublituximab  (U2):  UNITY-CLL  is  a  global  Phase  3  randomized
controlled clinical trial that includes two key objectives: first, to demonstrate contribution of each agent in the ublituximab plus umbralisib
regimen (the combination sometimes referred to as "U2"), and second, to demonstrate superiority in PFS over the standard of care to support
the submission for full approval of the combination. The study randomized patients into four treatment arms: ublituximab plus umbralisib,
ublituximab alone, umbralisib alone, and an active control arm of obinutuzumab plus chlorambucil. The primary endpoint for this study is
progression  free  survival  (PFS).  The  UNITY-CLL  trial  is  being  led  by  John  Gribben,  MD,  professor  of  Medical  Oncology,  Barts  Cancer
Institute,  United  Kingdom.  The  study  completed  enrollment  in  October  2017  with  over  600  patients  across  the  four  treatment  arms,  with
approximately 420 patients in the U2 arm and the active control arm combined.

In  September  2015,  we  reached  an  agreement  with  the  FDA  regarding  a  SPA  on  the  design,  endpoints,  and  statistical  analysis
approach of the UNITY-CLL Phase 3 trial. The SPA provides agreement that the Phase 3 trial design adequately addresses objectives that, if
met, would support the regulatory submission for drug approval of both ublituximab and umbralisib in combination.

In  May  2017,  a  pre-specified  interim  analysis  was  conducted  to  assess  contribution  of  each  single  agent  in  the  ublituximab  plus
umbralisib combination regimen, which allowed for the early termination of both single agent arms. A second interim analysis was planned
to evaluate ORR to support accelerated approval when all patients in the U2 arm and the active control arm had at least 6 months of follow-
up. In September 2018, we announced that the independent Data Safety Monitoring Board (DSMB) reviewed ongoing data from the trial and
advised us that the second interim analysis of ORR could not be conducted at that time as the data were not sufficiently mature to conduct the
analysis.  Given  the  uncertainty  surrounding  the  timing  and  outcome  of  the  ORR  analysis,  as  well  as  the  significant  regulatory  hurdles
associated  with  accelerated  approval  in  CLL,  we  decided  to  continue  to  conduct  the  trial  under  the  SPA  and  seek  full  approval  for  U2  in
patients with CLL based on the PFS endpoint, if positive.

In  May  2020,  we  announced  the  UNITY-CLL  trial  met  the  primary  endpoint  of  improved  PFS  (p<.0001),  and  the  trial  would  be

stopped early for superior efficacy observed at the interim analysis.

In October 2020, we announced the FDA granted Fast Track designation to the combination of ublituximab and umbralisib for the
treatment of adult patients with CLL. The FDA previously granted Orphan Drug Designation (ODD) covering ublituximab in combination
with umbralisib for the treatment of CLL.

On  December  7,  2020,  we  presented  safety  and  efficacy  results  from  the  UNITY-  CLL  trial  at  the  ASH  annual  meeting,
demonstrating that U2 significantly improved PFS over obinutuzumab plus chlorambucil (HR=0.54, p<0.0001) as well as ORR (p<0.001) in
patients with CLL; with consistent PFS improvement across treatment naïve CLL (HR=0.48) and relapsed/refractory CLL (HR=0.60). Grade
3/4 Adverse Events (AEs) of clinical interest (U2 vs O+Chl) included elevated ALT (8.3% vs 1.0%), elevated AST (5.3% vs 2.0%), non-
infectious  colitis  (1.9%  vs  0%),  infectious  colitis  (0.5%  vs  0.5%),  pneumonitis  (0.5%  vs  0%),  rash  (2.4%  vs  0.5%),  and  opportunistic
infections (5.8% vs. 1.5%).

                Based on data from the UNITY-CLL Phase 3 trial, submissions of a Biologics License Application (BLA) and a supplemental New
Drug  Application  (sNDA)  were  made  for  ublituximab,  in  combination  with  UKONIQ,  as  a  treatment  for  patients  with  CLL  and  small
lymphocytic lymphoma (SLL). The BLA and sNDA have been accepted by the FDA and a Prescription Drug User Fee Act (PDUFA) goal
date of March 25, 2022 was set for both applications.

              On November 30, 2021, we announced the FDA notified the Company that it plans to host a meeting of the Oncologic Drugs
Advisory  Committee  (ODAC)  in  connection  with  its  review  of  the  pending  BLA/sNDA.  The  FDA’s  concern  giving  rise  to  the  ODAC
meeting appears to stem from an early preliminary analysis of overall survival (OS) from the UNITY-CLL trial which showed an imbalance
in favor of the control arm (HR: 1.23), though the result was not statistically significant. However, when excluding deaths related to COVID-
19, the two arms were approximately balanced (HR: 1.04) with again no statistically significant difference between the treatment groups with
regard to overall survival. Further, we shared that the FDA notified us that potential questions and discussion topics for the ODAC include:
the benefit-risk of the U2 combination in the treatment of CLL or SLL, and the benefit-risk of UKONIQ in relapsed/refractory marginal zone
lymphoma (MZL) or follicular lymphoma (FL). In addition, as part of the benefit-risk analysis, the FDA has raised concerns regarding the
overall safety profile of the U2 regimen, including adverse events (serious and Grade 3-4), discontinuations due to adverse

11

Table of Contents

events, and dose modifications, all of which are expected to be reviewed as part of the ODAC.  The date of the ODAC meeting has not yet
been determined, although the FDA has stated that it is targeting holding the ODAC meeting in March or April 2022. Given this timing, we
believe it is unlikely that the FDA will make a decision on the BLA/sNDA by the PDUFA goal date of March 25, 2022.

On  January  27,  2022,  we  shared  that  we  were  nearing  completion  of  a  submission  to  the  FDA  of  updated  OS  analyses  from  the
UNITY-CLL Phase 3 trial that showed an improvement from the preliminary data originally shared with the FDA in November 2021. The
original preliminary OS Hazard Ratio (HR) and the updated information were as of the same data cutoff of September 2021. On January 27,
2022, we also shared that the FDA imposed a partial clinical hold on select studies of U2 and its components for CLL and NHL. As a result
of the partial clinical hold, no new patients may be enrolled to the select CLL/NHL studies identified by the FDA, however patients on these
studies who are deriving clinical benefit can continue on therapy. The partial clinical hold appears to be based on the same concerns that gave
rise to the previously disclosed ODAC meeting and not based on any new information provided by the Company to the FDA. Most studies
included in the partial clinical hold were previously closed to new enrollment or were on Company administrative hold to new enrollment.

On  February  3,  2022,  the  FDA  released  a  Drug  Safety  Communication  in  which  it  announced  that  it  is  investigating  a  possible
increased risk of death with UKONIQ based on the same concerns that gave rise to the previously disclosed ODAC meeting and not based on
any new information provided by the Company to the FDA. In the Drug Safety Communication, the FDA stated that it is re-evaluating the
benefit-risk  profile  of  UKONIQ  for  its  approved  indications.  The  FDA  encouraged  healthcare  providers  to  review  patients’  progress  on
UKONIQ  and  discuss  with  them  the  risks  and  benefits  of  continuing  UKONIQ  in  the  context  of  other  available  treatments.  The
communication  also  encouraged  patients  to  speak  with  their  healthcare  providers  about  the  risks  and  benefits  of  UKONIQ  and  possible
alternative treatments.

ULTRA-V Phase 2/3 Trial Evaluating U2 plus Venetoclax in CLL: The ULTRA-V trial is open-label, multicenter, registration-
directed clinical trial designed to investigate the efficacy and safety of U2 combined with venetoclax in subjects with treatment naïve and
relapsed or refractory CLL. The study is being conducted in two parts. The initial Phase 2 portion completed enrollment of approximately
165 patients in 1Q 2021. The Phase 3 portion commenced at approximately the same time. The ULTRA-V trial is being led Dr. Richard R.
Furman, Morton Coleman, MD Distinguished Professor of Medicine Weill Cornell Medical College.  

The  ULTRA-V  Phase  2  portion  of  the  trial  is  an  open-label,  multi-center,  clinical  trial,  evaluating  the  efficacy  and  safety  of  U2
combined with venetoclax in patients with treatment naïve and relapsed or refractory CLL. The primary endpoints for this study are ORR and
Complete Response (CR) rate. 

The ULTRA-V Phase 3 portion of the trial is an open-label, multi-center, randomized, controlled clinical trial comparing the time-
limited  triple  combination  of  U2  plus  venetoclax  to  an  active  control  arm  of  continuous  U2.  The  Phase  3  trial  includes  two  independent
randomized cohorts of CLL subjects: a treatment-naïve cohort and a previously treated cohort, with each cohort being enrolled and evaluated
independently of each other. The primary endpoint for the trial is PFS.

GENUINE Phase 3 Trial Evaluating Ublituximab plus Ibrutinib: GENUINE is a randomized controlled clinical trial evaluating
patients with previously treated CLL with specific high-risk cytogenetic abnormalities. Patients in this trial were randomized to receive either
ublituximab plus ibrutinib or ibrutinib alone. In February 2021, final results from this trial were published in The Lancet Haematology, in a
manuscript  titled,  “A  Phase  3,  Randomized  Trial  of  Ublituximab  Plus  Ibrutinib  for  Patients  With  Relapsed/Refractory  High-Risk  Chronic
Lymphocytic Leukemia”.

ULTIMATE I & II Trials Evaluating Single Agent Ublituximab in RMS: ULTIMATE I and ULTIMATE II are two independent
Phase 3 trials. Each trial is a global, randomized, multi-center, double-blinded, double-dummy, active-controlled study evaluating the efficacy
and  safety/tolerability  of  ublituximab  (450mg  dose  administered  by  one  hour  intravenous  infusion  every  six  months,  following  a  Day  1
infusion of 150mg over four hours, and a Day 15 infusion of 450mg over one hour) to teriflunomide (14mg oral tablets taken once daily) in
subjects with RMS. The primary endpoint for each study is ARR following 96 weeks of treatment. This program is being led by Lawrence
Steinman, MD, George A. Zimmermann Professor and Professor of Pediatrics, Neurology and Neurological Sciences at Stanford University.

Table of Contents

In August 2017, we reached an agreement with the FDA regarding a SPA on the design of the ULTIMATE I and ULTIMATE II
trials, for the treatment of RMS. The SPA provides agreement that the two Phase 3 trial designs adequately address objectives that, if met,
would support the regulatory submission for approval of ublituximab in RMS.

In  August  2018,  we  announced  that  target  enrollment  into  the  ULTIMATE  I  and  II  trials  had  been  achieved,  and  that  enrollment
would continue into September 2018 to allow identified patients to participate in the study. At completion of full enrollment in October of
2018, approximately 1,100 subjects were enrolled in both studies combined.

In  October  2019,  at  the  35th  Congress  of  ECTRIMS,  we  presented  the  ULTIMATE  I  &  II  Phase  3  program  trial  design  and

demographic data. The presentation concluded that patient baseline characteristics were consistent with a typical RMS population.

In December 2020, we announced positive topline results from the ULTIMATE I & II trials. Both studies met their primary endpoint
of significantly reducing ARR over a 96-week period (p<0.005 in each study) with ublituximab demonstrating an ARR of <0.10 in each of
the studies. Relative reductions of approximately 60% and 50% in ARR over teriflunomide were observed in ULTIMATE I & II, respectively.
 Key secondary MRI endpoints were also met. 

              In April 2021, data from the ULTIMATE I & II trials were presented for the first time at the American Academy of Neurology
Annual meeting. Additional data from these trials has been presented at various other medical meetings.

             On December 14, 2021, we announced that the FDA accepted a BLA for ublituximab as a treatment for patients with RMS. The FDA
set  a  PDUFA  goal  date  of  September  28,  2022  and  notified  the  Company  that  it  is  not  currently  planning  to  hold  an  advisory  committee
meeting to discuss this application.

Current Early-Stage Clinical Development of Ublituximab and Umbralisib

● Phase  1/2  Study  of  Umbralisib,  Ublituximab  and  Venetoclax  in  patients  with  relapsed  or  refractory  CLL  –  In  September
2021,  we  presented  data  from  patients  with  relapsed/refractory  CLL  treated  with  the  triple  therapy  combination  of  ublituximab,
umbralisib and venetoclax during the XIX International Workshop on Chronic Lymphocytic Leukemia (iwCLL). The regimen was
administered with 3 cycles of U2 as induction in cycles 1 through 3, U2 plus venetoclax in cycles 4, 5 and 6, followed by umbralisib
plus  venetoclax  in  cycles  7  through  12  in  patients  with  relapsed  or  refractory  (R/R)  CLL.  Patients  with  centrally  confirmed
undetectable minimal residual disease (uMRD) in the bone marrow after cycle 12 were permitted to stop all therapy, while MRD
detectable  patients  continued  on  single  agent  umbralisib.  47  patients  have  now  been  treated  as  of  the  data  cutoff  with  57%  of
patients previously exposed to a BTK inhibitor. Best Overall Response Rate (ORR) was 100% amongst evaluable patients (n=46),
including 37% complete response (CR) rate. At cycle 12, 91% of patients (n=34) achieved undetectable minimal residual disease
(uMRD) in the peripheral blood (PB), and 72% of patients (n=32) achieved uMRD in the bone marrow (BM). At a median follow
up of 24.5 months, median progression-free survival has not been reached. Grade 3/4 adverse events (AEs) occurring in >5% of
patients were neutropenia (28%), leukopenia (15%), lymphocytopenia (15%), infusion related reactions (9%), diarrhea (9%), and
anemia (6%). No TLS events were observed during venetoclax administration.

● Phase 1 Study of TG-1701, a Once-Daily BTK inhibitor, as a Single Agent and in Triple Combination with Umbralisib and
Ublituximab in patients with relapsed or refractory NHL and CLL – In December 2021, we presented data from patients with
relapsed/refractory NHL and CLL treated with TG-1701 monotherapy and the triple therapy combination of TG-1701, umbralisib
and ublituximab during the ASH annual meeting and exposition. A total of 135 patients with R/R CLL or B-cell lymphoma were
included in this presentation, with patients receiving 200 mg of TG-1701 in a dose-expansion cohort (n=61), 300 mg of TG-1701 in
a CLL dose-expansion cohort (n=20), TG-1701 in combination with U2 in a dose escalation cohort (TG-1701 doses ranging from
100 – 300 mg once daily and umbralisib at either 600 mg or 800mg) (n=21), and a triple combination expansion cohort of 100mg of
TG-1701 plus U2 (400 mg of umbralisib) (n=33). Overall Response Rate (ORR) and Complete Response (CR) outcomes included:
100%  ORR  observed  in  the  CLL  300  mg  QD  TG-1701  monotherapy  expansion  cohort  at  a  median  follow  up  of  13.8  months
(n=19); 95% ORR observed in the CLL 200 mg QD TG-1701 monotherapy expansion cohort at a median follow up of 20 months
(n=20); 86% ORR, including 19% CR rate, observed in the 1701+U2 dose escalation cohort (using doses of 100 mg to 300 mg QD
of  TG-1701)  at  a  median  follow  up  of  20.2  months  (n=21);  83%  ORR,  including  6%  CR  rate,  observed  in  the  1701+U2  dose
expansion cohort (using 100 mg QD of TG-1701 and 400 mg QD of umbralisib) at a median follow up of 2.7 months (n=18). Grade
3/4  AEs  occurring  in  patients  treated  with  200  mg  QD  of  TG-1701  (n=61)  and  300  mg  QD  of  TG-1701  (n=20),  respectively,
included neutropenia (8%, 20%), ALT increased (3%, 5%), AST increased (2%, 5%) and anemia (5%, 0%). Grade 3/4 AEs

occurring in patients treated with the triple combination in the U2 plus TG-1701 expansion cohort (100 mg QD TG-1701 plus 400
mg  QD  of  umbralisib;  n=19)  and  U2  plus  TG-1701  escalation  cohort  (100  mg  to  300  mg  QD;  n=21),  respectively,  included
neutropenia  (16%,  19%),  ALT  increased  (5%,  19%),  and  AST  increased  (5%,  14%).  At  the  time  of  data  cut-off,  no  patients  had
discontinued treatment due to a treatment-related adverse event across all cohorts.

● Phase  2  Study  Evaluating  the  Addition  of  Ublituximab  and  Umbralisib  (U2)  to  Ibrutinib  in  Patients  with  Chronic
Lymphocytic Leukemia (CLL): A Minimal Residual Disease (MRD)-Driven, Time-Limited Approach-Limited Approach –
In December 2021 at the ASH annual meeting we presented data from this trial which utilized an “add-on” approach, where the
combination of umbralisib and ublituximab (U2) was added to therapy in patients who were on ibrutinib for greater than 6 months
and had detectable minimum residual disease (MRD). Patients who achieve undetectable MRD (uMRD) or those who completed 24
cycles  of  therapy  with  detectable  MRD  stop  all  therapy  and  enter  a  period  of  treatment-free  observation  (TFO).  Patients  with
clinical  progression  during  TFO  are  eligible  for  re-treatment  with  the  U2  +  ibrutinib  combination.  28  patients  with  chronic
lymphocytic leukemia (CLL) were enrolled, with 27 evaluable for efficacy. Patients were on ibrutinib for a median of 21 months
(range  7-67)  prior  to  study  entry.  77%  of  evaluable  patients  achieved  uMRD,  with  a  median  time  to  first  uMRD  of  7.4  months.
Grade 3/4 AEs included diarrhea (4%), hypertension (7%), ALT/AST increased (4%) and COVID-19 (4%).

● Phase  I/II  Study  of  Umbralisib  (TGR-1202),  Ublituximab  (TG-1101),  and  Pembrolizumab  in  Patients  with  Relapsed  or
Refractory  Chronic  Lymphocytic  Leukemia  and  Richter’s  Transformation:  5-Year  Follow-up  –  In  September  2021  we
presented data from this trial at the XIX iwCLL conference. A total of 20 patients with R/R CLL or Richter’s Transformation (RT)
were treated with the triple combination of ublituximab, umbralisib, and pembrolizumab. Patients with CLL received 2 cycles of the
U2  regimen  before  pembrolizumab  was  added  for  an  additional  4  cycles,  followed  by  umbralisib  maintenance.  Patients  with  RT
received U2 + pembrolizumab for the first 4 cycles, followed by U2 maintenance. Twenty patients were evaluable for safety (11
CLL patients and 9 RT patients) and 19 were evaluable for efficacy (11 CLL and 8 RT). The triple combination was well tolerated,
with  immune  mediated  toxicities  not  appearing  above  what  would  be  expected  with  either  umbralisib  or  pembrolizumab  alone.
Grade 3/4 AEs occurring in >20% of patients (n=20) include, neutropenia (45%), thrombocytopenia (15%), ALT increase (15%),
leukopenia (10%), nausea (5%), fatigue (5%), and anemia (5%). In this heavily pre-treated cohort with a median of 2 (1-9) prior
lines  of  therapy:  91%  ORR  in  patients  with  R/R  CLL  (n=11);  83%  ORR  in  BTK  refractory  CLL  patients  (n=6),  with  4  of  5
responders achieving a response to U2 alone at the patient’s first efficacy assessment, prior to the addition of pembrolizumab; %
ORR in patients with RT (n=8), including 25% CR.

Early Pipeline Overview and Clinical Development

TG-1501 (Cosibelimab) Overview

Cosibelimab (also referred to as TG-1501) is a fully human monoclonal antibody of IgG1 subtype that binds to Programmed Death-
Ligand  1  (PD-L1)  and  blocks  its  interactions  with  PD-1  and  B7.1  receptors.  Cancer  cells  elude  anti-tumor  immunity  through  multiple
mechanisms, including upregulated expression of ligands for inhibitory immune checkpoint receptors. Signals from PD-L1 on tumor cells
and  in  the  tumor  microenvironment  help  those  tumors  avoid  immune  attack  and  elimination  by  preventing  activation  of  tumor  specific
effector T-cells. Anti-PD-L1 antibodies are designed to block that signal, permitting effector T-cells to attack the cancer. Clinical studies have
shown  that  blockade  of  the  PD-1/PD-L1  pathway  by  monoclonal  antibodies  can  enhance  the  immune  response  and  result  in  anti-tumor
activity.

Preclinically, it has been shown that the effects of anti-PD-L1 intervention can be enhanced by utilizing other mechanisms targeting
the  tumor  microenvironment.  Combining  immunotherapies  like  anti-PD-L1,  which  counters  the  tumor's  immune-evading  defense  system
with other anti-cancer agents such as ublituximab or umbralisib, may better engage the body's own immune system to help fight cancer.

A  comprehensive  array  of  in  vitro  biochemical  and  cellular  assays  was  established  to  characterize  the  binding  and  the  functional
activities of cosibelimab. The in vitro data demonstrated that the affinity, PD-L1 binding capability, relative ability to inhibit PD-1/PDL-1
interactions, and functional activity of cosibelimab in cellular assays are comparable to those of atezolizumab, durvalumab and avelumab -
the currently approved products sharing the same mechanism of action.

Cosibelimab is currently being evaluated in ongoing studies of patients with select solid tumors, by our licensor.

Table of Contents

In December 2018, the FDA approved an IND for cosibelimab and a Phase 1 study in subjects with select subtypes of lymphoma
commenced  in  2019,  as  did  a  study  of  cosibelimab  in  combination  with  ublituximab  and/or  umbralisib.  Based  on  our  rapidly  evolving
understanding of the pathobiology of lymphoma subtypes, we envision further combinations with other immunotherapies in the future.

TG-1701 (BTK inhibitor) Overview

TG-1701 is a novel, orally available and covalently-bound Bruton’s tyrosine kinase (BTK) inhibitor that exhibits superior selectivity

to BTK compared to ibrutinib in in vitro kinase screening.

B-cell receptor (BCR) signaling is crucial for normal B-cell development and supports the survival and growth of malignant B-cells
in  patients  with  B-cell  leukemias  or  lymphomas.  Targeting  BTK,  an  essential  element  of  BCR  signaling  pathway  which  regulates  the
survival, activation, proliferation, and differentiation of B lymphocytes, has shown remarkable efficacy with an acceptable safety profile in B-
cell malignancies.

In June 2018, pre-clinical data for TG-1701 demonstrating favorable pharmacologic properties was presented at the 23rd Congress
of the European Hematology Association (EHA) in Stockholm, Sweden. In vitro pharmacology studies have revealed that TG-1701 inhibited
BTK with greater than 10-fold selectivity as measured by IC50 on the kinase activities of EGFR, ITK, TXK, JAK3, HER2 and HER4. In vivo
pharmacology  studies  showed  that  TG-1701  significantly  inhibited  the  growth  of  xenograft  lymphoid  tumors  including  OCI-LY-10  and
DOHH-2 in nude mice.

We are currently evaluating TG-1701 in a Phase 1, multi-center, dose-escalation clinical trial in patients with B-cell malignancies.
This trial is designed to evaluate the safety and tolerability of TG-1701 alone and in combination with U2 in adults with B-cell malignancies
and determine the recommended Phase 2 dose. Key secondary objectives include evaluation of pharmacokinetics (PK), pharmacodynamics,
and preliminary anticancer activity. Data from this trial was most recently presented at ASH 2021 (described above).

TG-1801 (anti-CD47/anti-CD19 bispecific monoclonal antibody) Overview

TG-1801 is a first-in-class, bispecific CD47 and CD19 antibody. It is the first therapy to target both CD19, a B-cell specific market
widely expressed across B-cell malignancies, and CD47, the "don’t eat me" signal used by both healthy and tumor cells to evade macrophage
mediated phagocytosis. CD47 is expressed ubiquitously on normal cells, including red blood cells and platelets. CD19  is  a  specific  B-cell
marker, expressed early during pre-B cell ontogeny and until terminal differentiation into early plasma cells. The majority of B-cell lineage
malignancies (more than 90%) express CD19, including NHL, CLL and acute lymphoblastic leukemia (ALL). Tumor B-cells that have lost
the  expression  of  CD20  after  anti-CD20  mAb  therapy,  have  been  found  to  maintain  the  expression  of  CD19,  making  CD19  an  attractive
target in the treatment of B cell malignancies. By co-targeting both CD47 and CD19, TG-1801 has the potential to overcome the limitations
of existing CD47 targeted therapies by avoiding the side effects caused by indiscriminate blockade of CD47 on healthy cells. In addition to
potentially enhancing tolerability, the co-targeting of CD19 by TG-1801 may provide a secondary mechanism of direct anti-tumor activity
through the engagement of effector cells and induction of ADCC.

TG-1801 binds to human CD19 with significantly higher affinity than towards CD47. This difference between its affinity to CD19
and CD47 allows TG-1801 to bind and selectively block CD47 on CD19+ B-cells but not on CD19-  red  blood  cells  or  platelets  in  human
peripheral blood.

In in vitro assays, TG-1801 induces antibody-dependent cellular phagocytosis (ADCP) and ADCC of malignant tumor B-cell lines
and primary tumor B-cells from patients with B-cell acute lymphoblastic leukemia (B-ALL), B-cell chronic lymphocytic leukemia (B-CLL)
and numerous subtypes of NHL.

In in vivo mouse tumor models, treatment with TG-1801 inhibited tumor growth in Raji cell subcutaneous xenograft model, NALM-
6 cell disseminated tumor model, and patient-derived xenograft models, including primary tumor cells from patients with diffuse large B-cell
lymphoma  (DLBCL)  and  B-ALL.  In  addition,  the  combination  of  rituximab  and  TG-1801  demonstrated  enhanced  activity  over  TG-1801
monotherapy.

In summary, TG-1801 demonstrates anti-tumor activity in both in vitro assays (ADCP and ADCC) and in vivo animal tumor models.

In the first quarter of 2019, we commenced a Phase 1 first-in-human, dose-escalation study of TG-1801. This study is evaluating

escalating doses of TG-1801 in patients with B-Cell lymphoma. The primary objective of the study is to determine the recommended Phase

15

 
 
 
 
 
 
 
  
 
 
 
 
Table of Contents

2 dose and to characterize the safety profile of TG-1801. Key secondary objectives are to evaluate the pharmacokinetics of TG-1801 and its
preliminary anticancer activity

In  the  first  half  of  2021,  we  commenced  a  second  Phase  1  study  of  TG-1801  in  the  US  to  continue  dose  optimization  as

monotherapy and in combination with ublituximab. Enrollment in this study is ongoing.

INTELLECTUAL PROPERTY AND PATENTS

General

Our  goal  is  to  obtain,  maintain  and  enforce  patent  protection  for  our  products,  formulations,  processes,  methods  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. Our policy is to actively seek to obtain, where appropriate, the broadest intellectual property protection
possible for our product candidates, proprietary information and proprietary technology through a combination of contractual arrangements
and patents, both in the U.S. and elsewhere in the world.

We also depend upon the skills, knowledge and experience of our scientific and technical personnel, as well as that of our advisors,
consultants and other contractors. This knowledge, trade secrets, proprietary information and experience we call “know-how.” To help protect
our proprietary know-how, which is not patentable, and for inventions for which patents may be difficult to enforce, we rely on trade secret
protection and confidentiality agreements to protect our interests. To this end, we seek to protect our proprietary technology and processes, in
part,  by  entering  into  confidentiality  agreements  with  our  collaborators,  scientific  advisors,  employees  and  consultants,  and  invention
assignment  agreements  with  our  employees  and  consultants.  There  can  be  no  assurance,  however,  that  we  can  prevent  unauthorized
disclosure or use of our trade secrets, know-how and proprietary information despite the existence of confidentiality agreements.

Patents  and  other  proprietary  rights  are  crucial  to  the  development  of  our  business.  We  will  be  able  to  protect  our  proprietary
technologies from unauthorized use by third parties only to the extent that our proprietary rights are covered by valid and enforceable patents,
supported by regulatory exclusivity or are effectively maintained as trade secrets. We have a number of patents and patent applications related
to  our  compounds  and  other  technology,  but  we  cannot  guarantee  the  scope  of  protection  of  the  issued  patents,  or  that  such  patents  will
survive a validity or enforceability challenge, or that any of the pending patent applications will issue as patents.

Generally,  patent  applications  in  the  U.S.  are  maintained  in  secrecy  for  a  period  of  18  months  or  more.  Since  publication  of
discoveries  in  the  scientific  or  patent  literature  often  lags  behind  actual  discoveries,  we  are  not  certain  that  we  were  the  first  to  make  the
inventions covered by each of our pending patent applications or that we were the first to file those patent applications. The patent positions
of biotechnology and pharmaceutical companies are highly uncertain and involve complex legal and factual questions. Therefore, we cannot
predict  the  breadth  of  claims  allowed  in  biotechnology  and  pharmaceutical  patents,  or  their  enforceability.  To  date,  there  has  been  no
consistent policy regarding the breadth of claims allowed in biotechnology patents. Third parties or competitors may challenge or circumvent
our  patents  or  patent  applications,  if  issued.  If  our  competitors  prepare  and  file  patent  applications  in  the  U.S.  that  claim  technology  also
claimed by us, we may have to participate in interference proceedings declared by the U.S. Patent and Trademark Office to determine priority
of invention, which could result in substantial cost, even if the eventual outcome is favorable to us. Because of the extensive time required for
development, testing and regulatory review of a potential product, it is possible that before we commercialize any of our products, any related
patent  may  expire  or  remain  in  existence  for  only  a  short  period  following  commercialization,  thus  reducing  any  advantage  of  the  patent.
However, the life of a patent covering a product that has been subject to regulatory approval may have the ability to be extended through the
patent restoration program, although any such extension could still be minimal. If a patent is issued to a third party containing one or more
preclusive  or  conflicting  claims,  and  those  claims  are  ultimately  determined  to  be  valid  and  enforceable,  we  may  be  required  to  obtain  a
license under such patent or to develop or obtain alternative technology. In the event of litigation involving a third-party claim, an adverse
outcome in the litigation could subject us to significant liabilities to such third party, require us to seek a license for the disputed rights from
such third party, and/or require us to cease use of the technology. Further, our breach of an existing license or failure to obtain a license to
technology required to commercialize our products may seriously harm our business. We also may need to commence litigation to enforce
any patents issued to us or to determine the scope and validity of third-party proprietary rights. Litigation would involve substantial costs.

We, or those companies from which we have licensed our drug candidates, file patent applications directed to our drug candidates in
an effort to establish intellectual property positions regarding these new chemical entities as well as uses of these new chemical entities in the
treatment  of  diseases.  We  also  file  patent  applications  directed  to  novel  combinations  of  our  drugs  together  and  with  drugs  developed  by
others. The intellectual property portfolios for our most advanced drug candidates as of February 2022 are summarized below. Each of these
portfolios contains one or more pending patent applications covering our products and product candidates and uses and combinations thereof.
For those patents, prosecution is in progress. Prosecution is a lengthy process, during which the scope of the claims initially submitted for
examination by the USPTO is often significantly narrowed by the time they issue, if they issue at all. This may be the case with respect to our
pending patent applications referred to below.

UKONIQ (umbralisib)

TG-1801 (anti-CD47/anti-CD19 bispecific antibody)

Pursuant  to  our  joint  venture  and  license  option  agreement  with  Novimmune,  we  maintain  an  exclusive  option,  exercisable  at
specific  times  during  development,  to  license  the  commercial  rights  to  a  series  of  global  patent  applications  and  patents,  and  the  non-
exclusive right to certain technology patent applications. Patents directed to a bispecific antibody have issued in Australia, China, Europe,
Japan,  and  Russia  and  are  pending  in  other  jurisdictions  including  the  U.S.  Any  patents  maturing  from  these  pending  applications  are
expected to expire no sooner than December 2033.

Limitations on Patent Rights and Trade Secrets

The patent rights that we own or have licensed relating to our product candidates are limited in ways that may affect our ability to
exclude third parties from competing against us if we obtain regulatory approval to market these product candidates. See “Item 1A – Risk
Factors -- Risks Related to the Company’s Intellectual Property.” In addition, the limited patent protection may adversely affect the value of
our products or product candidates and may inhibit our ability to obtain a corporate partner at terms acceptable to us, if at all.

Proof  of  direct  infringement  by  a  competitor  for  method  of  use  patents  can  prove  difficult  because  the  competitors  making  and
marketing a product typically do not engage in the patented use. Additionally, proof that a competitor contributes to or induces infringement
of a patented method of use by another can also prove difficult because an off-label use of a product could prohibit a finding of contributory
infringement, and inducement of infringement requires proof of intent by the competitor.

Moreover, physicians may prescribe such a competitive identical product for indications other than the one for which the product has
been approved, or off-label indications, that are covered by the applicable patents. Although such off-label prescriptions may directly infringe
or contribute to or induce infringement of method of use patents, such infringement is difficult to prevent or prosecute.

Orphan Drug Designation  

In addition to patent protection, we may utilize orphan drug regulations or other provisions of the Food, Drug and Cosmetic Act of
1938, as amended, or FDCA, to provide market exclusivity for certain of our drug candidates. Orphan drug regulations provide incentives to
pharmaceutical  and  biotechnology  companies  to  develop  and  manufacture  drugs  for  the  treatment  of  rare  diseases,  currently  defined  as
diseases that exist in fewer than 200,000 individuals in the U.S., or, diseases that affect more than 200,000 individuals in the U.S. but that the
sponsor does not realistically anticipate will generate a net profit. Under these provisions, a manufacturer of a designated orphan-drug can
seek tax benefits, and the holder of the first FDA approval of a designated orphan product will be granted a seven-year period of marketing
exclusivity for such FDA-approved orphan product.

Pursuant to these regulations, ublituximab received Orphan Drug Designation from the FDA for the treatment of MZL (Nodal and
Extranodal)  in  September  2013,  for  the  treatment  of  CLL  in  August  of  2010,  and  Orphan  Drug  Designation  by  the  European  Medicines
Agency (EMA) for the treatment of CLL in November of 2009.

We  also  obtained  Orphan  Drug  Designation  for  umbralisib  as  monotherapy  for  the  treatment  of  CLL  in  August  2016,  for  the
treatment of nodal, extranodal, and splenic MZL in April 2019, and for the treatment of FL in March 2020. In addition, in January 2017, we
announced  that  the  FDA  granted  Orphan  Drug  Designation  covering  the  combination  of  ublituximab  and  umbralisib  for  the  treatment  of
patients with CLL and DLBCL.

U.S. Patent Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of the FDA approval of our drug candidates, some of our U.S. patents may be
eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to
as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation
for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the
remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-
half the time between the effective date of an IND and the submission date of an NDA or BLA plus the time between the submission date of
an NDA or BLA and the approval of that application. Only one patent applicable to an approved drug is eligible for the extension and the
application for the extension must be submitted prior to the expiration of the patent. The USPTO, in consultation with the FDA, reviews and
approves the application for any patent term extension or restoration. An application for a patent term extension for

18

 
Table of Contents

UKONIQ has been submitted, and we intend to apply for, or work with our licensing partners to apply for, patent term extensions for any
products  approved  by  the  FDA  in  the  future,  depending  on  the  factors  involved  in  the  development  program  and  filing  and  review  of  the
relevant NDA or the BLA.

Also, under the Hatch-Waxman Amendments, drugs that are new chemical entities (NCEs) are eligible for a five-year period of non-
patent marketing exclusivity in the United States. During the exclusivity period, the FDA may not accept for review an abbreviated new drug
application, or ANDA, or a 505(b)(2) NDA submitted by another company for another drug based on the same active moiety, regardless of
whether the drug is intended for the same indication as the original innovator drug or for another indication, where the applicant does not own
or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains
a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder. The Hatch-
Waxman  Amendments  also  provide  three  years  of  marketing  exclusivity  for  an  NDA,  or  supplement  to  an  existing  NDA  if  new  clinical
investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to
the approval of the application, for example new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only
the  modification  for  which  the  drug  received  approval  on  the  basis  of  the  new  clinical  investigations.  During  this  period,  FDA  will  not
approve  an  application  filed  by  a  third  party  for  the  protected  conditions  of  use  that  relies  on  any  of  the  data  from  the  new  clinical
investigations that was submitted by the innovator company. Five-year and three-year exclusivity will not delay the submission or approval of
a full NDA that does not rely on the innovator company’s data.

The Biologics Price Competition and Innovation Act of 2009 (BPCIA) created a 12-year period of data exclusivity for innovator
biologics.  FDA  therefore  cannot  approve  a  biosimilar  application  relying  on  data  for  a  specific  reference  product  until  12  years  after  the
reference  product  is  first  licensed.  BLA  supplements  are  not  eligible  for  any  additional  exclusivity.  The  objectives  of  the  BPCIA  are
conceptually  similar  to  those  of  the  Hatch-Waxman  Act  described  above.  The  implementation  of  an  abbreviated  approval  pathway  for
biological products is under the direction of the FDA. Since the enactment of the BPCIA, the FDA has issued several draft guidance’s for
industry  related  to  the  BPCIA,  addressing  scientific,  quality  and  procedural  issues  relevant  to  an  abbreviated  application  for  a  biosimilar
product. As of December 2021, the FDA had approved 33 biosimilar applications.

Orphan  drug  exclusivity,  as  described  below,  may  offer  a  seven-year  period  of  marketing  exclusivity,  except  in  certain
circumstances.  Pediatric  exclusivity  is  another  type  of  regulatory  market  exclusivity  in  the  United  States.  Pediatric  exclusivity,  if  granted,
adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity
protection or patent term, may be granted based on the voluntary completion of a pediatric trial in accordance with an FDA-issued “Written
Request” for such a trial.

LICENSING AGREEMENTS AND COLLABORATIONS

We  have  formed  strategic  alliances  with  a  number  of  companies  for  the  manufacture  and  commercialization  of  our  products.  Our

current key strategic alliances are discussed below.

Ublituximab

LFB Biotechnologies S.A.S, GTC Biotherapeutics, LFB/GTC LLC.

In January 2012, we entered into an exclusive license agreement with LFB Biotechnologies, GTC Biotherapeutics, and LFB/GTC
LLC,  all  wholly-owned  subsidiaries  of  LFB  Group,  relating  to  the  development  and  commercialization  of  ublituximab.  Under  the  license
agreement, we have acquired the exclusive worldwide rights for the development and commercialization of ublituximab. As of December 31,
2021,  we  paid  LFB  Group  approximately  $7.0  million  related  to  the  achievement  of  certain  milestones  under  the  license  agreement.  LFB
Group  is  eligible  to  receive  payments  of  up  to  an  aggregate  of  approximately  $31.0  million  upon  our  successful  achievement  of  certain
clinical  development,  regulatory  and  sales  milestones,  in  addition  to  royalty  payments  on  net  sales  of  ublituximab  at  a  royalty  rate  that
escalates from mid-single digits to high-single digits. The license will terminate on a country by country basis upon the expiration of the last
licensed patent right or 15 years after the first commercial sale of a product in such country, unless the agreement is earlier terminated (i) by
LFB if the Company challenges any of the licensed patent rights, (ii) by either party due to a breach of the agreement, or (iii) by either party
in the event of the insolvency of the other party.

Ildong Pharmaceutical Co. Ltd.

In November 2012, we entered into an exclusive (within the territory) sublicense agreement with Ildong relating to the development
and  commercialization  of  ublituximab  in  South  Korea  and  Southeast  Asia.  Under  the  terms  of  the  sublicense  agreement,  Ildong  has  been
granted a royalty bearing, exclusive right, including the right to grant sublicenses, to develop and commercialize ublituximab in South Korea,
Taiwan, Singapore, Indonesia, Malaysia, Thailand, Philippines, Vietnam, and Myanmar. To date, we have received $2 million in the form of
an  upfront  payment  from  Ildong  and  are  eligible  to  receive  sales-based  milestone  payments  up  to  an  aggregate  of  $5  million  and  royalty
payments  on  net  sales  of  ublituximab  at  a  royalty  rate  that  escalates  from  mid-teens  to  high-teens  upon  approval  in  South  Korea  and/or
Southeast Asia. The license will terminate on a country by country basis upon the expiration of the last licensed patent right or 15 years after
the first commercial sale of a product in such country, unless the agreement is earlier terminated (i) by Ildong if the Company challenges any
of the licensed patent rights, (ii) by either party due to a breach of the agreement, or (iii) by either party in the event of the insolvency of the
other party.

UKONIQ (umbralisib)

In  September  2014,  we  exercised  our  option  to  license  the  global  rights  to  umbralisib,  thereby  entering  into  an  exclusive  licensing
agreement (the Umbralisib License) with Rhizen Pharmaceuticals, S A (Rhizen) for the development and commercialization of umbralisib.
Prior to this, we had been jointly developing umbralisib in a 50:50 joint venture with Rhizen.

Under the terms of the TGR-1202 License, Rhizen received a $4.0 million cash payment and 371,530 shares of our common stock as
an  upfront  license  fee.  For  the  year  ended  December  31,  2021,  we  paid  Rhizen  $12.0  million  as  part  of  a  primary  indication  approval
milestone  for  launch  of  product  in  the  US  in  accordance  with  the  terms  of  the  Umbralisib  License.  Rhizen  will  be  eligible  to  receive
additional approval and sales-based milestone payments in the aggregate of approximately $175 million payable upon approval in multiple
jurisdictions  for  up  to  two  oncology  indications  and  one  non-oncology  indication  and  attaining  certain  sales  milestones.  In  addition,  if
umbralisib is co-formulated with another drug to create a new product (a New Product), Rhizen will be eligible to receive similar regulatory
approval and sales-based milestone payments for such New Product. Additionally, Rhizen receives tiered royalties that escalate from high
single  digits  to  low  double  digits  on  any  net  sales  of  umbralisib  and  any  New  Product.  Rhizen  shall  also  be  eligible  to  participate  in
sublicensing revenue, if any, based on a percentage that decreases as a function of the number of patients treated in clinical trials following
the exercise of the license option. Rhizen will retain global manufacturing rights to umbralisib, provided that they are price competitive with
alternative manufacturers. The license will terminate on a country-by-country basis upon the expiration of the last licensed patent right or any
other  exclusivity  right  in  such  country,  unless  the  agreement  is  earlier  terminated  (i)  by  us  for  any  reason,  or  (ii)  by  either  party  due  to  a
breach of the agreement.

Cosibelimab

In March 2015, we entered into a global collaboration (the Collaboration) with Checkpoint Therapeutics, Inc. (Checkpoint) for the
development  and  commercialization  of  Checkpoint’s  anti-PD-L1  and  anti-GITR  antibody  research  programs  in  the  field  of  hematological
malignancies  with  an  option  to  acquire  rights  in  autoimmune  diseases.  These  antibodies  were  generated  at  Dana-Farber  Cancer  Institute
(Dana-Farber). In June 2019, we amended our Collaboration Agreement with Checkpoint to cover additional licenses necessary to continue
the  development  of  the  anti-PD-L1  and  anti-GITR  research  programs.  Under  the  terms  of  the  initial  Collaboration,  we  made  an  up-front
payment of $0.5 million, and upon entering into the amended agreement, made an additional payment of $1.0 million. In March 2020, we
achieved  the  first  milestone  event,  and  we  subsequently  paid  Checkpoint  $1.0  million  as  part  of  this  milestone.  Under  the  terms  of  the
amended agreement, we will make development and sales-based milestone payments up to an aggregate of approximately $110 million and
will pay a tiered low double-digit royalty on net sales. The royalty term will terminate on a country by country basis upon the later of (i) ten
years after the first commercial sale of any applicable licensed product in such country, or (ii) the expiration of the last-to-expire patent held
by Dana Farber containing a valid claim to any licensed product in such country.

TG-1701 (BTK inhibitor)

In January 2018, we entered into a global exclusive license agreement with Jiangsu Hengrui Medicine Co., (Hengrui), to acquire
worldwide  intellectual  property  rights,  excluding  Asia  but  including  Japan,  and  for  the  research,  development,  manufacturing,  and
commercialization of products containing or comprising of any of Hengrui’s Bruton’s Tyrosine Kinase inhibitors containing the compounds
of either TG-1701 (SHR-1459 or EBI-1459) or TG-1702 (SHR-1266 or EBI-1266) for hematologic malignancies. Pursuant to the agreement,
we  paid  Hengrui  an  upfront  fee  of  $1.0  million  in  our  common  stock  in  April  2018.  In  addition,  in  July  2019,  we  paid  Jiangsu  the  first
milestone under the agreement of $0.1 million in our common stock. In July 2020, we paid Hengrui $2.0 million as part of a milestone in
accordance  with  the  license  agreement.  Hengrui  is  eligible  to  receive  milestone  payments  totaling  approximately  $350  million  upon  and
subject to the achievement of certain milestones. Various provisions allow for payments in conjunction with the agreement to be made in cash
or our common stock, while others limit the form of payment. Royalty payments in the low double digits are due on net sales of licensed
products and revenue from sublicenses. Additionally, before we can license, sell, develop, or commercialize ublituximab within China, we
must notify Hengrui, giving Hengrui the right of first offer. The agreement allows combinations of TG-1701 or TG-1702 with umbralisib,
ublituximab,  or  U2.  Additional  combinations  may  be  undertaken  under  the  agreement  subject  to  additional  pre-specified  payments  to
Hengrui.

The term of the agreement expires after the expiration of the last royalty term to expire with respect to any of the patent rights under
the  agreement.  We  or  Hengrui  may  terminate  the  agreement  upon  notice  to  the  other  upon  breach  without  remedy  or  upon  insolvency.  In
addition, either party may terminate the agreement upon a material breach, after providing the other party with adequate notice and allowing
45 days to cure.

TG-1801 (anti-CD47/anti-CD19 bispecific antibody)

In June 2018, we entered into a Joint Venture and License Option Agreement with Novimmune SA (Novimmune) to collaborate on
the development and commercialization of Novimmune’s novel first-in-class anti-CD47/anti-CD19 bispecific antibody known as TG-1801
(previously  NI-1701).  The  companies  will  jointly  develop  the  product  on  a  worldwide  basis,  focusing  on  indications  in  the  area  of
hematologic B-cell malignancies. We serve as the primary responsible party for the development, manufacturing and commercialization of
the product. Pursuant to the agreement, in June 2018 we paid Novimmune an upfront payment of $3.0 million in our common stock. Further
milestone  payments  will  be  paid  based  on  early  clinical  development,  and  the  Company  will  be  responsible  for  the  costs  of  clinical
development  of  the  product  through  the  end  of  the  Phase  2  clinical  trials,  after  which  the  Company  and  Novimmune  will  be  jointly
responsible  for  all  development  and  commercialization  costs.  The  Company  and  Novimmune  will  each  maintain  an  exclusive  option,
exercisable at specific times during development, for the Company to license the rights to TG-1801, in which case Novimmune is eligible to
receive additional milestone payments totaling approximately $185 million as well as tiered royalties on net sales in the high single to low
double digits upon and subject to the achievement of certain milestones.

IRAK4

In  June  2014,  we  entered  into  an  exclusive  licensing  agreement  with  Ligand  Pharmaceuticals  Incorporated  (Ligand)  for  the
development and commercialization of Ligand's interleukin-1 receptor associated kinase-4 (IRAK4) inhibitor technology, which currently is
in preclinical development for potential use against certain cancers and autoimmune diseases. IRAK4 is a serine/threonine protein kinase that
is a key downstream signaling component of the interleukin-1 receptor and multiple toll-like receptors.

Under the terms of the license agreement, Ligand received 125,000 shares of our common stock as an upfront license fee. Ligand
will also be eligible to receive maximum potential milestone payments of approximately $207.0 million upon the achievement of specific
clinical,  regulatory  and  commercial  milestone  events.  Additionally,  Ligand  will  be  entitled  to  royalties  on  our  future  net  sales  of  licensed
products containing IRAK4 inhibitors. The basic royalty rate for licensed products covered by Ligand's issued patents will be 6% for annual
sales of up to $1 billion and 9.5% for annual sales in excess of that threshold. The license will terminate on a country by country basis upon
the expiration of the last licensed patent right or 10 years after the first commercial sale of a product in such country, unless the agreement is
earlier terminated by either party due to a breach of the agreement in the event of the insolvency of the other party.

TG-1601 (BET)

In  May  2016,  as  part  of  a  broader  agreement  with  Jubilant  Biosys  (Jubilant),  we  entered  into  a  sub-license  agreement  (JBET
Agreement)  with  Checkpoint  for  the  development  and  commercialization  of  Jubilant’s  novel  BET  inhibitor  program  in  the  field  of
hematological  malignancies.  The  BET  inhibitor  program  is  the  subject  of  a  family  of  patents  covering  compounds  that  inhibit  BRD4,  a
member of the BET (Bromodomain and Extra Terminal) domain for cancer treatment. Our BET inhibitor program is currently in pre-clinical
development.

Under the terms of the agreement, we paid Checkpoint an up-front licensing fee of $1.0 million and will make additional payments
contingent  on  certain  preclinical,  clinical,  and  regulatory  milestones,  including  commercial  milestones  totaling  up  to  approximately  $177
million and a single-digit royalty on net sales. TG will also provide funding to support certain targeted research efforts at Jubilant.

COMPETITION

Competition in the pharmaceutical and biotechnology industries is intense. Our competitors include pharmaceutical companies and
biotechnology  companies,  as  well  as  universities  and  public  and  private  research  institutions.  In  addition,  companies  that  are  active  in
different  but  related  fields  represent  substantial  competition  for  us.  Many  of  our  competitors  have  significantly  greater  capital  resources,
larger research and development staffs and facilities and greater experience in drug development, regulation, manufacturing and marketing
than we do. These organizations also compete with us to recruit qualified personnel, attract partners for joint ventures or other collaborations,
and license technologies that are competitive with ours. To compete successfully in this industry, we must identify novel and unique drugs or
methods of treatment and then complete the development of those drugs as treatments in advance of our competitors.

The drugs that we are attempting to develop will have to compete with existing therapies. In addition, a large number of companies
are pursuing the development of pharmaceuticals that target the same diseases and conditions that we are targeting. Some of these potential
competing drugs are further advanced in development than our drug candidates and may be commercialized earlier. The resulting changes in
standard of care can impact the likelihood of regulatory accelerated approval opportunities for our drug candidates.

For  the  cancer  indications  for  which  we  received  FDA  approval  of  UKONIQ  or  for  which  we  are  developing  U2  and  our  other

product candidates, there are a number of established therapies with which we will compete:

● For the treatment of MZL, we expect UKONIQ to compete with zanubrutinib (BeiGene), ibrutinib (AbbVie and Janssen), and the

combination of rituximab and lenalidomide (Bristol-Myers Squibb), as well as established treatments such as rituximab (Roche) and
several generically available chemotherapies. In addition, there are investigational PI3K inhibitors being developed in MZL.
● For the treatment of FL, we expect UKONIQ to compete with recently approved drugs such as axicabtagene ciloleucel (Gilead),
obinutuzumab (Roche), tazemetostat (Epizyme), and the combination of rituximab and lenalidomide (Bristol-Myers Squibb), and
established treatments such as rituximab (Roche), and several generically available chemotherapies, many of which have FDA-
approved indications for earlier lines of therapy (e.g., after two prior lines of systemic therapy) than UKONIQ. There are also PI3K
delta inhibitors in earlier stages of development for FL.

● For the treatment of CLL, if U2 is approved, we expect the regimen to compete with approved drugs such as ibrutinib (AbbVie and
Janssen), acalabrutinib (AstraZeneca), venetoclax (AbbVie and Roche), obinutuzumab (Roche), idelalisib (Gilead) and duvelisib
(Secura Bio, Inc.), and established treatments such as rituximab (Roche), and several generically available chemotherapies.
Additionally, there are second generation BTK inhibitors similar to ibrutinib in late-stage clinical testing for CLL that could enter
the market. These agents can be used as monotherapy or in combination with one or more of the other agents.

● In addition, a number of pharmaceutical companies are developing antibodies and bispecific antibodies targeting CD20, CD19,
CD47 and other B-cell associated targets, chimeric antigen receptor T-cell (CAR-T) immunotherapy, and other B-cell ablative
therapy which, if approved, would potentially compete with U2 and UKONIQ.

For  Multiple  Sclerosis  for  which  we  are  developing  ublituximab,  there  are  a  number  of  established  therapies  with  which  we  will

compete:

● If ublituximab is approved, we expect ublituximab will primarily compete against other CD20-targeted agents, while the group of
CD20-targeted agents will also compete broadly against a number of already approved MS therapies. Currently, there are two anti-
CD20 monoclonal antibodies approved, ocrelizumab (Roche) and ofatumumab (Novartis).

22

Table of Contents

Cosibelimab, TG-1701 and TG-1801 if approved will also face competition from drugs on the market and under development in the

same therapeutic class as each of those drugs.

Additional information can be found under Item “1A - Risk Factors – Other Risks Related to Our Business” within this report.

SUPPLY AND MANUFACTURING

We  have  limited  experience  in  manufacturing  products  for  clinical  or  commercial  purposes.  We  currently  do  not  have  any
manufacturing  capabilities  of  our  own.  We  have  established  a  contract  manufacturing  relationship  for  the  supply  of  ublituximab  with
Samsung  Biologics.  For  the  supply  of  umbralisib,  Rhizen  has  established  contract  manufacturing  relationships  as  part  of  our  licensing
agreement.  As  with  any  supply  program,  obtaining  pre-clinical  and  clinical  materials  of  sufficient  quality  and  quantity  to  meet  the
requirements of our development programs cannot be guaranteed and we cannot ensure that we will be successful in this endeavor.

Process improvements and other changes are common during clinical development to accommodate raw material and component
variability,  enhance  productivity  and/or  accommodate  different  or  larger  equipment  utilized  during  the  scale-up  process  required  for
commercial manufacture. These types of incremental process changes have been made during clinical development for both TG’s small and
large molecule programs. For example, our UNITY-CLL Phase 3 clinical trial contains ublituximab produced from both a pre-commercial
process and the current commercial process. While there are some analytical differences between the two materials, we do not expect those
differences to have an effect on the clinical performance of ublituximab. The primary difference is that the commercial process has resulted in
further enhancement to the ADCC effect, potentially enhancing potency. We will analyze the Phase 3 data to ensure that the materials are
substantially similar in performance. If there are material differences in safety or efficacy, we may need to adjust our statistical analysis of the
Phase 3 study, which could impact the approvability of the U2 combination in CLL.

At the time of commercial sale, to the extent possible and commercially practicable, we would seek to engage back-up suppliers for
raw materials, manufacturing and testing services for each of our product candidates. Until such time, we expect that we will rely on a single
contract  manufacturer  to  produce  each  of  our  product  candidates  under  current  Good  Manufacturing  Practice,  or  cGMP,  regulations.  Our
third-party  manufacturers  have  a  limited  number  of  facilities  in  which  our  product  candidates  can  be  produced  and  will  have  limited
experience in manufacturing our product candidates in quantities sufficient for commercialization. Our third-party manufacturers will have
other clients and may have other priorities that could affect their ability to perform the work satisfactorily and/or on a timely basis. Both of
these occurrences would be beyond our control.

We expect to similarly rely on contract manufacturing relationships for any products that we may in-license or acquire in the future.

However, there can be no assurance that we will be able to successfully contract with such manufacturers on terms acceptable to us, or at all.

Contract manufacturers in the U.S. are subject to ongoing periodic and unannounced inspections by the FDA, the Drug Enforcement
Administration if applicable, and corresponding state agencies to ensure strict compliance with cGMP and other state and federal regulations.
Contract manufacturers outside of the United States face similar challenges from the numerous local and regional agencies and authorized
bodies.  We  do  not  have  control  over  third-party  manufacturers’  compliance  with  these  regulations  and  standards,  other  than  through
contractual  obligations.  If  they  are  deemed  out  of  compliance  with  cGMPs,  product  recalls  could  result,  inventory  could  be  destroyed,
production could be stopped and supplies could be delayed or otherwise disrupted.

If we need to change manufacturers after commercialization, the FDA and corresponding foreign regulatory agencies must approve
these  new  manufacturers  in  advance,  which  will  involve  testing,  regulatory  submissions,  and  additional  inspections  to  ensure  compliance
with FDA regulations and standards and may require significant lead times and delay. Furthermore, switching manufacturers may be difficult
because the number of potential manufacturers is limited. It may be difficult or impossible for us to find a replacement manufacturer quickly
or on terms acceptable to us, or at all.

GOVERNMENT AND INDUSTRY REGULATION

Numerous  governmental  authorities,  principally  the  FDA  and  corresponding  state  and  foreign  regulatory  agencies,  impose
substantial regulations upon the clinical development, manufacture and marketing of our product candidates, as well as our ongoing research
and  development  activities.  We,  along  with  our  third-party  contractors,  will  be  required  to  navigate  the  various  pre-  and  post-approval
requirements of the governing regulatory agencies of the jurisdictions in which we wish to conduct clinical studies or market our product

23

 
Table of Contents

candidates. None of our product candidates, except UKONIQ, have been approved for sale in any market in which we have marketing rights.
Before  marketing  in  the  U.S.,  any  drug  that  we  develop  must  undergo  rigorous  pre-clinical  testing  and  clinical  trials  and  an  extensive
regulatory review and approval process implemented by the FDA under the FDCA and, in the case of biologics, the Public Health Service
Act (PHS Act). The FDA regulates, among other things, the pre-clinical and clinical testing, safety, efficacy, approval, manufacturing, quality
control and assurance, record keeping, pharmacovigilance and adverse event reporting, packaging, labeling, storage, advertising, promotion,
import  and  export,  sale  and  distribution  of  biopharmaceutical  products.  The  process  of  obtaining  regulatory  approvals  and  the  subsequent
compliance with applicable federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial
resources.

Product Development and Applications for Marketing Authorization

The regulatory review and approval process is lengthy, expensive and uncertain. We are required to submit extensive pre-clinical and
clinical data and supporting information to the FDA for each indication or use to establish a drug candidate’s safety and efficacy before we
can  secure  FDA  approval  to  market  or  sell  a  product  in  the  U.S.  The  approval  process  takes  many  years,  requires  the  expenditure  of
substantial resources and may involve ongoing requirements for post-marketing studies or surveillance. Before commencing clinical trials in
humans,  we  must  submit  an  IND  to  the  FDA  containing,  among  other  things,  pre-clinical  data,  chemistry,  manufacturing  and  control
information, and an investigative plan. Our submission of an IND may not result in FDA authorization to commence a clinical trial.

For purposes of clinical development and to pursue NDA or BLA approval, clinical trials are typically conducted in the following

sequential phases:

● Phase 1: The drug is administered to a small group of humans, either healthy volunteers or patients, to test for safety, dosage

tolerance, absorption, metabolism, excretion, and clinical pharmacology.

● Phase 2: Studies are conducted on a larger number of patients to assess the efficacy of the product, to ascertain dose tolerance and

the optimal dose range, and to gather additional data relating to safety and potential adverse events.

● Phase 3: Studies establish safety and efficacy in an expanded patient population.
● Phase 4: The FDA may require Phase 4 post-marketing studies to find out more about the drug’s long-term risks, benefits, and

optimal use, or to test the drug in different populations.

Clinical testing must meet requirements for institutional review board oversight, informed consent and good clinical practices, and
must  be  conducted  pursuant  to  an  IND,  unless  exempted.  In  addition,  the  FDA,  equivalent  foreign  regulatory  authority,  or  a  data  safety
monitoring  committee  for  a  trial  may  place  a  clinical  trial  on  hold  or  terminate  it  if  it  concludes  that  subjects  are  being  exposed  to  an
unacceptable health risk, or for futility. Any drug is likely to produce some toxicity or undesirable side effects in animals and in humans when
administered at sufficiently high doses and/or for a sufficiently long period of time. Unacceptable toxicity or side effects may occur at any
dose  level  at  any  time  in  the  course  of  studies  in  animals  designed  to  identify  unacceptable  effects  of  a  drug  candidate,  known  as
toxicological  studies,  or  clinical  trials  of  drug  candidates.  The  appearance  of  any  unacceptable  toxicity  or  side  effect  could  cause  us  or
regulatory authorities to interrupt, limit, delay or abort the development of any of our drug candidates and could ultimately prevent approval
by the FDA or foreign regulatory authorities for any or all targeted indications.

The  length  of  time  necessary  to  complete  clinical  trials  varies  significantly  and  may  be  difficult  to  predict.  Clinical  results  are
frequently susceptible to varying interpretations that may delay, limit or prevent regulatory approvals. Additional factors that can cause delay
or termination of our clinical trials, or that may increase the costs of these trials, include:

● slow patient enrollment due to the nature of the clinical trial plan, the proximity of patients to clinical sites, the eligibility criteria for

participation in the study or other factors;

● inadequately trained or insufficient personnel at the study site to assist in overseeing and monitoring clinical trials or delays in

approvals from a study site’s review board;

● longer treatment time required to demonstrate efficacy or determine the appropriate product dose;
● insufficient supply of the drug candidates;
● adverse medical events or side effects in treated patients; and
● ineffectiveness of the drug candidates.

For clinical trials that are intended to form the basis of a new drug or biologics license application for approval, sponsors of drugs
may apply for an SPA from the FDA, by which the FDA provides official evaluation and written guidance on the design and size of proposed
protocols.  While  obtaining  an  SPA  provides  some  assurance  the  design  of  a  trial  should  be  sufficient  for  approval,  the  final  marketing
approval depends on the results of efficacy, the adverse event profile and an evaluation of the benefit/risk of treatment demonstrated in the

24

Table of Contents

Phase  3  trial.  The  SPA  agreement  may  only  be  changed  through  a  written  agreement  between  the  sponsor  and  the  FDA,  or  if  the  FDA
becomes aware of a substantial scientific issue essential to product safety or efficacy.

In  September  2015,  we  reached  an  agreement  with  the  FDA  regarding  an  SPA  on  the  design,  endpoints  and  statistical  analysis
approach of a Phase 3 clinical trial, referred to as the UNITY-CLL trial, for the proprietary combination of ublituximab and umbralisib, for
the treatment of CLL. The SPA provides agreement that the Phase 3 trial design adequately addresses objectives that, if met, would support
the regulatory submission for drug approval of both ublituximab and umbralisib in combination. Additionally, in August 2017, we reached an
agreement with the FDA regarding an SPA on the design of two Phase 3 clinical trials for ublituximab, referred to as the ULTIMATE I and
ULTIMATE II Phase 3 clinical trials, for the treatment of relapsing forms of Multiple Sclerosis (RMS). The SPA provides agreement that the
two Phase 3 trial designs adequately address objectives that, if met, would support the regulatory submission for approval of ublituximab.
Despite obtaining an SPA the trials may not be positive and even if positive may not support FDA approval.

The FDA may permit expedited development, evaluation, and marketing of new therapies intended to treat persons with serious or
life-threatening conditions for which there is an unmet medical need under its expedited drug development programs. A sponsor can apply for
Fast Track designation at the time of submission of an IND, or at any time prior to receiving marketing approval of the new drug application,
or NDA. To receive Fast Track designation, an applicant must demonstrate:

● that the drug is intended to treat a serious or life-threatening condition; and
● that nonclinical or clinical data demonstrate the potential to address an unmet medical need.

The FDA must respond to a request for Fast Track designation within 60 calendar days of receipt of the request. Over the course of
drug development, a product in a Fast Track development program must continue to meet the criteria for Fast Track designation. Sponsors of
products  in  Fast  Track  drug  development  programs  must  be  in  regular  contact  with  the  reviewing  division  of  the  FDA  to  ensure  that  the
evidence necessary to support marketing approval will be developed and presented in a format conducive to an efficient review. Sponsors of
products in Fast Track drug development programs are also permitted to submit portions of an NDA or BLA to the FDA on a rolling basis
where the FDA may consider reviewing portions of a marketing application before the sponsor submits the complete application.

In addition, sponsors may also apply to the FDA for Breakthrough Therapy Designation (BTD). The procedures and requirements
for BTD are similar to those required for Fast Track such that the Breakthrough Therapy Designation is intended to expedite the development
and review of a potential new drug for serious or life-threatening diseases, however, with BTD, there is a further requirement that the sponsor
present “preliminary clinical evidence” which “indicates that the drug may demonstrate substantial improvement over existing therapies on
one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development.” The designation of
a drug as a Breakthrough Therapy was enacted as part of the 2012 Food and Drug Administration Safety and Innovation Act.

In January 2019, we announced that the FDA granted Breakthrough Therapy Designation for umbralisib for the treatment of adult
patients with marginal zone lymphoma (MZL) who have received at least one prior anti-CD20 regimen based on interim results from a subset
of patients from the MZL cohort of the UNITY-NHL clinical trial.

Sponsors  of  drugs  granted  Fast  Track  or  breakthrough  therapy  designation  also  may  seek  approval  under  the  FDA’s  accelerated
approval regulations. Under this authority, the FDA may grant marketing approval for a new drug product on the basis of adequate and well-
controlled  clinical  trials  establishing  that  the  drug  product  has  an  effect  on  a  surrogate  endpoint  that  is  reasonably  likely,  based  on
epidemiologic, therapeutic, pathophysiologic, or other evidence, to predict clinical benefit or on the basis of an effect on a clinical endpoint
other than survival or irreversible morbidity. To obtain accelerated approval a sponsor must be able to demonstrate the drug candidate treats a
serious condition, provides a meaningful advantage over other available therapies, and demonstrates an effect on a surrogate endpoint that is
reasonably likely to predict clinical benefit. Many companies have filed for accelerated approval and have subsequently failed to obtain such
approval  for  a  variety  of  reasons.  To  the  extent  a  product  does  obtain  an  accelerated  approval,  such  approval  will  be  subject  to  the
requirement that the applicant study the drug further in a post-marketing confirmatory clinical trial to verify and describe its clinical benefit
where  there  is  uncertainty  as  to  the  relation  of  the  surrogate  endpoint  to  clinical  benefit  or  uncertainty  as  to  the  relation  of  the  observed
clinical  benefit  to  ultimate  outcome.  Accelerated  approval  is  sometimes  referred  to  as  conditional  approval  because  if  the  results  of  these
confirmatory clinical trials fail to verify clinical benefit, the FDA has the right to remove the drug from the market and has done so in the
recent  past.  Post-marketing  confirmation  studies  are  usually  underway  at  the  time  an  applicant  files  the  NDA.  When  required  to  be
conducted, such post-marketing confirmation studies must also be adequate and well-controlled. The applicant must carry out any such post-
marketing  confirmation  studies  with  due  diligence.  Completing  the  required  post-approval  clinical  studies  as  designed  can  be  difficult,
especially as the treatment landscape evolves. For example, the challenges in completing such studies have prompted some companies with
products that

25

Table of Contents

received accelerated approval for relapsed or refractory FL to withdraw that indication (e.g., duvelisib (December 2021), idelalisib (January
2022)).

In  February  2021,  we  obtained  accelerated  approval  of  UKONIQ  for  relapsed  or  refractory  MZL  who  have  received  at  least  one
prior anti-CD20-based regimen and for relapsed or refractory FL who have received at least three prior lines of systemic therapy. The FDA
approved these indications based on overall response rate. Continued approval for these indications may be contingent upon verification and
description of clinical benefit in a confirmatory trial.

It  is  also  becoming  more  common  for  the  FDA  to  request  a  Risk  Evaluation  and  Mitigation  Strategy,  or  REMS,  as  part  of  an
NDA/BLA. The REMS plan contains post-market obligations of the sponsor to train prescribing physicians, monitor off-label drug use, and
conduct Phase 4 follow-up studies and registries to ensure the continued safe use of the drug.

The NDA and BLA review process also generally includes a pre-approval inspection, or PAI, to assess the manufacturing facilities
and  relevant  processes  and  data  for  compliance,  and  readiness  for  commercial  manufacture  in  accordance  with  cGMPs.  Among  the
conditions of approval is the requirement that a manufacturer’s quality systems and manufacturing procedures conform to cGMP. Even when
product approval is received, manufacturers must expend significant time, money and effort to ensure continued compliance, and the FDA
conducts periodic surveillance inspections to monitor the manufacturing process and drug quality and evaluate whether the manufacturers are
in compliance. It may be difficult for our manufacturers or us to comply with the applicable cGMP, as interpreted by the FDA, and other FDA
regulatory requirements. If we, or our contract manufacturers, fail to comply, then the FDA may not allow us to market products that have
been  affected  by  the  failure.  Many  drug  approvals  have  been  delayed  due  to  issues  at  contract  manufacturing  facilities.  If  we  were  to
experience  any  such  delay  that  would  negatively  impact  our  business  and  timeline  to  commercialization  of  any  of  our  drug  candidates
affected by such manufacturing issue.

Post-Approval Requirements

Any  products  for  which  we  receive  FDA  approval  are  subject  to  continuing  regulation  by  the  FDA  and  other  federal  and  state
regulators on a wide range of matters, including, among other things cGMPs and product quality, pharmacovigilance and reporting of adverse
events, product distribution requirements, fulfilling post-marketing or confirmatory study or REMS commitments, and complying with FDA
promotion  and  advertising  requirements.  Violations  of  the  FDCA  or  other  post-approval  regulatory  requirements  may  result  in  agency
enforcement actions, including withdrawal of approval, recall, seizure of products, warning letters, injunctions, fines and/or civil or criminal
penalties. Any agency enforcement action could have a material adverse effect on our business.

The FDA promotion and advertising requirements applicable to marketed products include, among other things, standards for direct-
to-consumer  advertising,  restrictions  against  promoting  products  for  uses  or  in  patient  populations  that  are  not  either  described  in  the
product’s approved indications and uses or otherwise consistent with the FDA-approved product labeling, limitations on industry-sponsored
scientific  and  educational  activities,  rules  regarding  communication  of  health  care  economic  information  regarding  biopharmaceutical
products to payors and formularies, and requirements for promotional activities involving the internet. Drugs whose review was accelerated
may carry additional requirements on marketing activities, including the requirement that all promotional materials are pre-submitted to the
FDA. Although a healthcare provider may prescribe a product for a use that has not been approved by the FDA when the healthcare provider
deems such use to be appropriate in his or her professional medical judgment, manufacturers may not market or promote unapproved uses.
Although court decisions have to some degree impacted FDA’s enforcement activity regarding alleged off-label promotion in light of First
Amendment considerations, there are still significant risks in this area, in part because there is the potential for False Claims Act exposure in
addition to the potential for enforcement under the FDCA.

After  product  approval,  quality  control  and  manufacturing  procedures  must  continue  to  conform  to  applicable  manufacturing
requirements. FDA regulations require among other things, quality control and quality assurance as well as the corresponding maintenance of
records  and  documentation  and  the  obligation  to  investigate  and  correct  any  deviations  from  cGMPs.  Manufacturers  and  other  entities
involved in the manufacture and distribution of approved products are required to register their establishments and list their products with the
FDA and certain state agencies. Manufacturers and their third-party contractors may be subject to periodic unannounced inspections by the
FDA  and  certain  state  agencies  for  assessment  of  compliance  with  cGMPs  and  other  applicable  laws.  Accordingly,  manufacturers  must
continue  to  expend  time,  money,  and  effort  in  the  areas  of  production  and  quality  control  to  maintain  quality  control  and  manufacturing
compliance.  Discovery  of  problems  with  a  product  after  approval  may  result  in  restrictions  on  a  product,  including,  among  other  things,
withdrawal of approval, recall or withdrawal of the product from the market. In addition, changes to the manufacturing process are strictly
regulated, and depending on the significance of the change, may require prior FDA approval or notification before being implemented. Other

26

Table of Contents

types of changes to the approved product, such as adding new indications and claims to the product labeling, are also subject to further FDA
review and approval.

Marketed products must meet the requirements of the Drug Supply Chain Security Act, or DSCSA, which regulates the commercial
distribution  of  prescription  drug  products  at  the  federal  level.  The  DSCSA  sets  certain  standards  for  federal  or  state  registration,  requires
tracing  of  products  through  the  pharmaceutical  distribution  supply  chain,  and  imposes  other  requirements  on  entities  in  the  supply  chain,
including manufacturers and repackagers, wholesale distributors, third-party logistics providers, and dispensers. The DSCSA requirements,
development of standards, and the system for product tracing have been and will continue to be phased in over a period of years, with FDA
indicating enforcement discretion on certain aspects due to the COVID-19 pandemic.

In  addition,  the  post-marketing  discovery  of  previously  unknown  problems  with  a  product  or  the  failure  to  comply  with  applicable
FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, warning letters from
the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly discovered
or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and
contraindications, and may require the implementation of other risk management measures.

From time to time, legislation is drafted, introduced and passed in Congress that could significantly change the statutory provisions
governing the approval, manufacturing and marketing of products regulated by the FDA. In addition to new legislation, FDA regulations,
guidance documents, and policies are often revised or reinterpreted by the agency in ways that may significantly affect our business. It is
impossible to predict whether further legislative or FDA regulation or policy changes will be enacted or implemented and what the impact of
such changes, if any, may be.

Should  we  wish  to  market  our  products  outside  the  U.S.,  we  must  receive  marketing  authorization  from  the  appropriate  foreign
regulatory  authorities.  The  requirements  governing  the  conduct  of  clinical  trials,  marketing  authorization,  pricing  and  reimbursement  vary
widely from country to country. Importantly, the level of evidence of efficacy and safety necessary to apply for marketing authorization for a
drug candidate differs from country to country. In particular, clinical trial endpoints, and the level of clinical evidence that may support an
accelerated approval filing with the FDA, such as the ORR data from the single-arm cohorts of the UNITY-NHL study that we used as the
basis for a filing and approval for UKONIQ in MZL and FL, may be insufficient to file for marketing applications outside of the U.S. At
present,  companies  are  typically  required  to  apply  for  foreign  marketing  authorizations  at  a  national  level.  However,  within  the  European
Union, centralized registration procedures are available to companies wishing to market a product across the European Union member states.
Typically,  if  the  regulatory  authority  is  satisfied  that  a  company  has  presented  adequate  evidence  of  safety,  quality  and  efficacy,  then  the
regulatory  authority  will  grant  a  marketing  authorization.  This  foreign  regulatory  approval  process,  however,  involves  risks  similar  or
identical to the risks associated with FDA approval discussed above, and therefore we cannot guarantee that we will be able to obtain the
appropriate marketing authorization for any product in any particular country.

Failure to comply with applicable federal, state and foreign laws and regulations would likely have a material adverse effect on our
business. In addition, federal, state and foreign laws and regulations regarding the manufacture and sale of new drugs are subject to future
changes. We cannot predict the likelihood, nature, effect or extent of adverse governmental regulation that might arise from future legislative
or administrative action, either in the U.S. or abroad.

Coverage and Reimbursement

Sales of our drugs will depend, in part, on the extent to which our drugs will be covered by third-party payors, such as government
health  programs,  commercial  insurance  and  managed  healthcare  organizations.  These  third-party  payors  are  increasingly  reducing
reimbursements for medical drugs and services. In addition, the containment of healthcare costs has become a priority of foreign and U.S.
federal and state governments, and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures and foreign
governments  have  shown  significant  interest  in  implementing  cost-containment  programs,  including  price  controls,  restrictions  on
reimbursement, importation, and requirements for substitution of generic drugs. Adoption of price controls and cost-containment measures,
and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results.
Decreases  in  third-party  reimbursement  for  our  drug  candidates,  if  approved,  or  a  decision  by  a  third-party  payor  to  not  cover  our  drug
candidates could reduce physician usage of such drugs and have a material adverse effect on our sales, results of operations and financial
condition.

In the U.S., the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of
2010,  or  collectively  the  Affordable  Care  Act,  enacted  in  March  2010,  has  had  a  significant  impact  on  the  health  care  industry.  The
Affordable  Care  Act  expanded  coverage  for  the  uninsured  while  at  the  same  time  containing  overall  healthcare  costs.  With  regard  to
pharmaceutical  products,  the  Affordable  Care  Act,  among  other  things,  created  a  new  average  manufacturer  price  definition  under  the
Medicaid Drug Rebate Program for drugs that are inhaled, infused, instilled, implanted or injected and not generally dispensed through the
retail channel, increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extended the
rebate program to individuals enrolled in Medicaid managed care organizations, established annual fees and taxes on manufacturers of certain
branded  prescription  drugs,  and  a  new  Medicare  Part  D  coverage  gap  discount  program,  in  which  manufacturers  must  agree  to  offer  50%
point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period (subsequent
legislation increased this to 70% effective as of January 1, 2019), as a condition for the manufacturer’s outpatient drugs to be covered under
Medicare Part D.

Since  the  enactment  of  the  Affordable  Care  Act,  certain  provisions  of  the  Affordable  Care  Act  have  been  subject  to  judicial
challenges as well as efforts to repeal or replace them or to alter their interpretation or implementation. For example, the Tax Cuts and Jobs
Act enacted on December 22, 2017 (the Tax Act), eliminated the shared responsibility payment for individuals who fail to maintain minimum
essential coverage under section 5000A of the Internal Revenue Code of 1986, commonly referred to as the individual mandate, effective
January 1, 2019. Although litigation and legislation over the Affordable Care Act are likely to continue, with unpredictable and uncertain
results, we expect that the Biden administration may seek to expand and strengthen the Affordable Care Act.

There  has  been  increasing  legislative  and  enforcement  interest  in  the  United  States  with  respect  to  drug  pricing  practices.
Specifically, there have been several recent U.S. Congressional inquiries and proposed federal and state legislation designed to, among other
things,  bring  more  transparency  to  drug  pricing,  reduce  the  cost  of  prescription  drugs  under  Medicare,  review  the  relationship  between
pricing  and  manufacturer  patient  programs,  and  reform  government  program  reimbursement  methodologies  for  drugs.  The  Biden
administration has indicated that lowering prescription drug prices is a priority and has proposed a number of measures to do so, including
allowing the federal government to negotiate prices for some high-cost drugs covered under Medicare Part B and Part D, requiring inflation
rebates to limit annual increases in drug prices in Medicare and private insurance, and capping out-of-pocket spending for Medicare Part D
enrollees.  Although the fate of these proposals remains uncertain, we expect that additional U.S. federal healthcare reform measures could be
adopted in the future, any of which could limit the amounts that the U.S. federal government will pay for healthcare products and services,
which could result in additional pricing pressures and reduced demand for any of our products that receive marketing approval.

At  the  state  level,  individual  states  are  increasingly  aggressive  in  passing  legislation  and  implementing  regulations  designed  to
control prescription drug pricing, including price and marketing cost disclosure and transparency measures, and, in some cases, authorizing
importation of prescription drugs from other countries. In addition, 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
health care programs. These measures could reduce the ultimate demand for our products or put pressure on our product pricing. We expect
that additional state healthcare reform measures will be adopted in the future, which could limit the amounts that state governments will pay
for healthcare products and services and result in additional pricing pressures.

In  addition,  in  some  foreign  countries,  the  proposed  pricing  for  a  prescription  drug  must  be  approved  before  the  drug  may  be
lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, the United Kingdom and
many  European  Union  member  states  have  robust  health  technology  assessment  processes  to  determine  pricing  and  reimbursement  for
pharmaceuticals through their national health insurance system. Many European Union members states also include either direct or indirect
price referencing, or other price control mechanisms, in determining the price of a pharmaceutical in their market. There can be no assurance
that  any  country  that  has  price  controls  or  reimbursement  limitations  for  pharmaceutical  drugs  will  allow  favorable  reimbursement  and
pricing arrangements for any of our products. Historically, drugs launched in the European Union do not follow price structures of the U.S.
and generally tend to be significantly lower.

Other U.S. Healthcare Laws

We may also be subject to healthcare regulation and enforcement by the federal government and the states and foreign governments
where we may market our product candidates, if approved. These laws include, without limitation: state and federal anti-kickback, fraud and
abuse,  false  claims,  privacy  and  security  laws;  laws  governing  interactions  with  healthcare  professionals  and  related  transparency
requirements (such as the federal Sunshine Act and a range of state biopharmaceutical marketing and transparency laws); and requirements
for manufacturers to report certain calculated product prices to the government or provide certain discounts or rebates to government

28

Table of Contents

authorities  or  private  entities,  often  as  a  condition  of  reimbursement  under  government  healthcare  programs.  The  compliance  and
enforcement  landscape  is  informed  by  government  enforcement  precedent  and  settlement  history,  Advisory  Opinions,  and  Special  Fraud
Alerts. The risks we face and our approach to compliance may evolve over time in light of these types of developments. The potential safe
harbors available for, example, relative to the Anti-Kickback Statute, are subject to change through legislative and regulatory action, and we
may decide to adjust our business practices or be subject to heightened scrutiny as a result.

The  federal  Anti-Kickback  Statute  prohibits,  among  other  things,  any  person  from  knowingly  and  willfully  offering,  soliciting,
receiving or paying remuneration, directly or indirectly, to induce either the referral of an individual, for an item or service or the purchasing
or ordering of a good or service, for which payment may be made under federal healthcare programs such as the Medicare and Medicaid
programs. The government has enforced the Anti-Kickback Statute to reach large settlements with healthcare companies based on research,
consulting  and  other  financial  arrangements  with  physicians  that  the  government  alleged  were  not  based  on  the  provision  of  bona  fide
services and were intended as an inducement or reward. A person or entity does not need to have actual knowledge of the statute or specific
intent to violate it in order to have committed a violation. In addition, the government may assert that a claim including items or services
resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims
Act.  The  majority  of  states  also  have  anti-kickback  laws,  which  establish  similar  prohibitions  and  in  some  cases  may  apply  to  items  or
services reimbursed by any third-party payor, including commercial insurers.

In addition, the civil False Claims Act prohibits, among other things, knowingly presenting or causing the presentation of a false,
fictitious  or  fraudulent  claim  for  payment  to  the  U.S.  government.  Actions  under  the  False  Claims  Act  may  be  brought  by  the  Attorney
General or as a qui tam action by a private individual in the name of the government. Violations of the False Claims Act can result in very
significant monetary penalties and treble damages. The federal government is using the False Claims Act, and the accompanying threat of
significant liability, in its investigation and prosecution of pharmaceutical and biotechnology companies throughout the U.S., for example, in
connection with the promotion of products for unapproved uses and other sales and marketing practices. The government has obtained multi-
million  and  multi-billion  dollar  settlements  under  the  False  Claims  Act  in  addition  to  individual  criminal  convictions  under  applicable
criminal  statutes.  Given  the  significant  size  of  actual  and  potential  settlements,  it  is  expected  that  the  government  will  continue  to  devote
substantial resources to investigating healthcare providers’ and manufacturers’ compliance with applicable fraud and abuse laws.

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, also created new federal criminal statutes that
prohibit  among  other  actions,  knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare  benefit
program, including private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully
obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact
or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items
or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific
intent to violate it in order to have committed a violation.

There has also been a recent trend of increased federal and state regulation of payments made to physicians and other healthcare
providers. The Affordable Care Act, among other things, imposes reporting requirements on drug manufacturers for payments made by them
to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members.
Failure  to  submit  required  information  may  result  in  civil  monetary  penalties  of  up  to  an  aggregate  of  $150,000  per  year  (or  up  to  an
aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests that are not
timely, accurately and completely reported in an annual submission. Drug manufacturers are required to submit annual reports to the Centers
for Medicare & Medicaid Services, which publicly posts the data on its website. Effective January 1, 2022, these reporting obligations will
extend  to  include  transfers  of  value  made  to  certain  non-physician  providers  such  as  physician  assistants  and  nurse  practitioners.  Certain
states also mandate implementation of compliance programs, impose restrictions on drug manufacturer marketing practices and/or require the
tracking and reporting of gifts, compensation and other remuneration to physicians.

We may also be subject to data privacy and security regulation by both the federal government and the states in which we conduct
our  business.  HIPAA,  as  amended  by  the  Health  Information  Technology  and  Clinical  Health  Act,  or  HITECH,  and  their  respective
implementing  regulations,  including  the  final  omnibus  rule  published  on  January  25,  2013,  imposes  specified  requirements  relating  to  the
privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s privacy and
security standards directly applicable to “business associates,” defined as independent contractors or agents of covered entities that create,
receive,  maintain  or  transmit  protected  health  information  in  connection  with  providing  a  service  for  or  on  behalf  of  a  covered  entity.
HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other
persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal

29

Table of Contents

HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, according to the U.S. Federal Trade
Commission, or the FTC, failing to take appropriate steps to keep consumers' personal information secure constitutes unfair acts or practices
in  or  affecting  commerce  in  violation  of  Section  5(a)  of  the  Federal  Trade  Commission  Act.  The  FTC  expects  a  company's  data  security
measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of
its  business,  and  the  cost  of  available  tools  to  improve  security  and  reduce  vulnerabilities.  Medical  data  is  considered  sensitive  data  that
merits  stronger  safeguards.  The  FTC's  guidance  for  appropriately  securing  consumers'  personal  information  is  similar  to  what  is  required
under HIPAA.

In addition, we may be subject to state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws
which  may  apply  to  items  or  services  reimbursed  by  any  third-party  payor,  including  commercial  insurers,  and  state  laws  governing  the
privacy  and  security  of  health  information  in  certain  circumstances,  many  of  which  differ  from  each  other  in  significant  ways,  thus
complicating compliance efforts. For example, the California Consumer Protection Act, or CCPA, which went into effect on January 1, 2020,
established a privacy framework for covered businesses by creating an expanded definition of personal information, data privacy rights for
consumers  in  California,  and  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. The CCPA was recently amended by the California Privacy
Rights Act (CPRA), expanding certain consumer rights such as the right to know. It remains unclear what, if any, additional modifications
will be made to these laws by the California legislature or how these laws will be interpreted and enforced. The potential effects of the CCPA
and CPRA are significant and may cause us to incur substantial costs and expenses to comply.

Rest of the World Healthcare Regulation

For  other  countries  outside  of  the  U.S.  and  the  European  Union,  the  requirements  governing  the  conduct  of  clinical  trials,  drug
licensing,  sales  and  marketing,  pricing  and  reimbursement  vary  from  country  to  country.  If  we  fail  to  comply  with  applicable  foreign
regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls,
seizure of products, operating restrictions and criminal prosecution.

European Union member states, the United Kingdom, Switzerland and other foreign jurisdictions have adopted data protection laws
and regulations, which impose significant compliance obligations. In the European Union and the United Kingdom, the collection and use of
personal data, including clinical trial data, is governed by the provisions of the General Data Protection Regulation, or GDPR. The GDPR,
together with national legislation, regulations and guidelines of the European Union member states and the United Kingdom 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 European
Union or the United Kingdom, security breach notifications, security and confidentiality of the personal data and imposition of substantial
potential fines for breaches of the data protection obligations. Compliance with the GDPR is a rigorous and time-intensive process that may
increase the cost of doing business to ensure full compliance. Furthermore, 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
European Union or United Kingdom.

Human Capital

As  of  February  25,  2022,  we  had  286  full-time  employees.  None  of  our  employees  are  represented  by  a  collective  bargaining

agreement, and we have never experienced a work stoppage.

We  believe  that  our  future  success  largely  depends  upon  our  continued  ability  to  attract  and  retain  a  diverse  workforce  of  highly
skilled and dedicated employees. We provide our employees with competitive salaries and bonuses and opportunities for equity ownership. In
addition,  we  provide  an  inclusive  and  collaborative  work  environment  with  learning  and  development  opportunities.  We  strive  to  foster  a
culture of diversity in backgrounds and ideas as we believe that diversity, equity, and inclusion are paramount to our success. We understand
that in order to perform at maximum capacity, our workforce needs to cultivate a welcoming and inclusive environment wherein employees
feel  they  can  represent  themselves  fully.  We  pride  ourselves  on  being  an  equal  opportunity  employer  and  strictly  prohibit  unlawful
discrimination based on color, religion, gender, sexual orientation, gender identity/expression, national origin/ancestry, age, disability, marital
and veteran status.

We expect to continue to grow our organization assuming we obtain FDA approval of U2 in CLL/SLL and ublituximab in RMS. We
will continue to evaluate the business needs and market opportunities, balancing in-house expertise and core competencies with outsourced
capacity.

Drug development and commercialization requires deep expertise across a broad array of disciplines. Pharmaceutical companies of
all sizes compete for a limited number of qualified applicants to fill specialized positions. To attract qualified candidates, the Company offers
an attractive total rewards package, consisting of base salary, cash bonus, a comprehensive benefit package, equity compensation, and 401(k)
plan. Bonus opportunities and equity compensation increase as a percentage of total compensation based on level of responsibility, and actual
bonus awards are based on performance.

You should carefully consider the following risk factors and the other information contained elsewhere in this Annual Report before
making an investment in our securities. If any of the following risks occur, our business, financial condition or operating results could be
materially harmed. An investment in our securities is speculative in nature, involves a high degree of risk, and should not be made by an
investor  who  cannot  bear  the  economic  risk  of  its  investment  for  an  indefinite  period  of  time  and  who  cannot  afford  the  loss  of  its  entire
investment. The risks described below are not the only ones that our business faces. Additional risks not currently known to us or that we
currently  deem  to  be  immaterial  may  adversely  impact  our  business  in  the  future.  Additionally,  many  of  these  risks  and  uncertainties  are
currently elevated by and may or will continue to be elevated by the COVID-19 pandemic.

Risks Related to the Development and Commercialization of U2 and UKONIQ® (umbralisib)

We face substantial uncertainty regarding whether FDA will approve U2 and whether we will be able to maintain approval of UKONIQ in
its currently marketed indications in light of the FDA’s plan to hold an ODAC meeting in March or April 2022 to discuss the benefit-risk
of U2 in CLL and SLL and the benefit risk of UKONIQ in R/R FL and MZL. If we are unable to obtain regulatory approval for U2 or if
we are unable to maintain current approvals of UKONIQ, our business will be materially harmed.

In November 2021, the Company announced that FDA plans to host a meeting of the Oncologic Drugs Advisory Committee (ODAC)
in connection with its review of the pending Biologics License Application (BLA) and supplemental New Drug Application (sNDA) for U2
for the treatment of adult patients with CLL and SLL. The potential questions and discussion topics for the ODAC include: the benefit-risk of
the  U2  combination  for  the  treatment  of  CLL  or  SLL,  and  the  benefit-risk  of  UKONIQ  for  R/R  MZL  and  FL.  In  addition,  as  part  of  the
benefit-risk analysis, the overall safety profile of the U2 regimen, including adverse events (serious and Grade 3-4), discontinuations due to
adverse events, and dose modifications, is expected to be reviewed. The FDA’s concerns giving rise to the ODAC meeting stem from an early
analysis of overall survival from the UNITY-CLL trial, which showed a possible increased risk of death in patients receiving U2 compared to
the control arm of obinutuzumab plus chlorambucil.

Due to the concerns that prompted the ODAC meeting, the FDA also placed the Company’s clinical trials investigating U2 and its
components in CLL and NHL, on partial clinical hold in January 2022. As part of the partial clinical hold, no new patients may be enrolled to
the  impacted  studies,  however  patients  on  these  studies  who  are  deriving  clinical  benefit  can  continue  on  therapy  once  they  have  been
reconsented. Most studies included in the partial clinical hold were already closed to new enrollment or were on TG administrative hold to
new enrollment at the time FDA imposed the partial clinical hold. TG expects to provide an update on the partial clinical hold only upon
completion of the ODAC meeting.

Additionally,  in  February  2022,  the  FDA  released  a  Drug  Safety  Communication  in  which  it  announced  that  it  is  investigating  a
possible increased risk of death with UKONIQ as a result of the initial UNITY-CLL overall survival results and is re-evaluating the benefit-
risk profile of UKONIQ for its approved indications. The FDA encouraged healthcare providers to review patients’ progress on UKONIQ
and discuss with them the risks and benefits of continuing UKONIQ in the context of other available treatments. The communication also
encouraged patients to speak with their healthcare providers about the risks and benefits of UKONIQ and possible alternative treatments.

The FDA's plan to convene an ODAC, issuance of a partial clinical hold on selected studies of U2 and its components, and release
of the Drug Safety Communication have adversely affected our business, and we expect that these agency actions will continue to do so until
the  FDA  makes  a  decision  on  the  BLA/sNDA  for  U2  for  the  treatment  of  CLL  and  SLL.  In  light  of  the  FDA’s  plan  to  hold  an  ODAC
meeting,  we  face  substantial  uncertainty  regarding  whether  FDA  will  approve  U2  and  whether  we  will  be  able  to  maintain  approval  of
UKONIQ. The ODAC and the FDA may rely on a different data set from UNITY-CLL, have a different interpretation of the results of that
study,  and  reach  a  different  assessment  of  the  benefit-risk  profile  of  U2  and  UKONIQ  than  we  do.  The  ODAC  may  recommend  against
approving  U2  and  against  maintaining  the  current  approvals  of  UKONIQ  or  may  provide  advisory  input  that  adversely  impacts  the
commercial opportunity for U2 and UKONIQ. Although we anticipate that the ODAC meeting will be scheduled in March or April 2022, we
do  not  know  how  long  it  will  take  after  the  ODAC  convenes  for  the  FDA  to  make  a  decision  on  our  BLA/sNDA  and  the  benefit-risk  of
UKONIQ in its approved indications. The full extent of the planned ODAC meeting is unknown. Even if the ODAC recommends approval of
U2 and continued approval of UKONIQ, the FDA may not agree with that recommendation if it determines that the applicable regulatory
criteria for approval are not satisfied or the FDA may require inclusion of warnings or limitations in the labeling that are not acceptable to
patients or healthcare providers. If we are unable to obtain regulatory approval for U2 or maintain approval of UKONIQ, our business will be
materially harmed. Furthermore, our business will be adversely affected if the partial clinical hold cannot be favorably resolved in a

32

Table of Contents

timely manner or if such regulatory concerns lead to more burdensome clinical or preclinical studies that cause significant delay or expense in
the research or development of U2 or UKONIQ.

Risks Related to Commercialization

If we obtain FDA approval of U2 in CLL/SLL or ublituximab in RMS and do not achieve broad market acceptance among physicians,
patients, healthcare payors, and the medical community, the revenues that we generate from product sales will be limited.

We have one marketed product, UKONIQ, which received accelerated approval from the FDA on February 5, 2021 for the treatment
of R/R MZL in adult patients who have received at least one prior anti-CD20-based regimen and R/R FL in adult patients who have received
at least three prior lines of systemic therapy. The FDA is currently reviewing our BLA and sNDA requesting approval of U2 as a treatment
for patients with CLL/SLL and our BLA for ublituximab for the treatment of RMS.

While  we  have  initiated  the  commercial  launch  of  UKONIQ  in  the  U.S.  and  have  started  internal  planning  for  potential
commercialization of ublituximab, we have limited experience as a commercial company and our ability to successfully overcome the risks
associated  with  commercializing  drugs  in  the  biopharmaceutical  industry,  including  the  risk  that  our  products  do  not  achieve  an  adequate
level of acceptance, remains uncertain. UKONIQ as well as other drugs that we may bring to the market in the future, including ublituximab,
may not gain market acceptance by physicians, patients, third-party payors and others in the healthcare community. If our products do not
achieve an adequate level of acceptance, we may not generate significant revenues or meet our revenue projections or guidance, and we may
not become profitable. The degree of market acceptance of UKONIQ, as well as any future product candidates for which we obtain approval
such as U2 in CLL/SLL and ublituximab in RMS, will depend on a number of factors, including: 

● the timing of our receipt of marketing approvals, the terms of such approvals, and the countries in which such approvals are

obtained;

● the efficacy, safety and tolerability as demonstrated in clinical trials and as compared to alternative treatments;
● the timing of market introduction of any of our product candidates as well as competitive products;
● the indications for which our products are approved, and other aspects of the approved labeling for such products;
● acceptance by physicians, major operators of cancer or neurology clinics, and patients of our products as safe, tolerable and

effective treatments;

● the potential and perceived advantages or disadvantages of our products compared to alternative treatments;
● our ability to offer our products for sale at competitive prices;
● the availability of adequate reimbursement by third-party payors and government authorities;
● the extent of patient cost-sharing obligations, including copays and deductibles;
● changes in regulatory requirements by government authorities for our products;
● relative convenience and ease of administration;
● the prevalence and severity of side effects and adverse events;
● the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;
● the effectiveness of our sales and marketing efforts;
● protecting our rights in our intellectual property portfolio;
● our ability to maintain a reliable supply of our products that meets market demand; and
● favorable or unfavorable publicity relating to our products or relating to the Company.

The  COVID-19  pandemic  continues  to  present  a  substantial  global  public  health  risk  and  economic  challenge.  The  measures  to
control  the  spread  of  COVID-19  have  impacted  our  approach  to  the  commercial  launch  of  UKONIQ  and  may  impact  our  ability  to
successfully launch ublituximab, if approved. We initiated commercial sales of UKONIQ in February 2021 in an environment in which the
measures  taken  by  state  and  local  governments  as  well  as  hospitals  and  oncology  clinics  to  control  the  spread  of  COVID-19  significantly
limited  our  opportunities  for  in-person  interactions,  including  for  example,  interactions  with  physicians,  hospitals,  payors,  and  other
customers  at  medical  congresses.  As  a  result  of  COVID-19  variants,  many  of  the  interactions  our  field  personnel  have  with  healthcare
providers  and  other  customers  continue  to  be  virtual.  We  cannot  ensure  that  remote  methods  will  be  effective  or  as  effective  as  in-person
interactions. Other factors related to the COVID-19 pandemic that could impact commercialization of our products include delays in demand
due  to  a  reduction  in  medical  visits  by  patients,  impacts  on  the  healthcare  system  and  overall  economy  and  increases  in  the  number  of
uninsured or underinsured patients. Patients and healthcare providers have raised concerns that immunosuppressive products, like anti-CD20
antibodies and other B-cell targeted agents, may increase the risk of acquiring COVID-19 or lead to more severe complications upon

33

Table of Contents

infection.  These  concerns  may  impact  the  commercial  potential  for  ublituximab  and  other  immunosuppressive  products  that  we  have  in
development. In addition, our office-based employees, consultants, vendors and certain customer segments are continuing to work remotely
and  many  of  our  commercialization  efforts  are  happening  virtually.  The  length  of  time  and  full  extent  to  which  the  COVID-19  pandemic
directly or indirectly impacts our commercialization efforts depends on future developments that are highly uncertain, subject to change and
are  difficult  to  predict,  including,  whether,  even  after  pandemic-related  restrictions  ease,  there  is  a  shift  in  how  pharmaceutical  field
representatives interact with healthcare providers that could have a negative effect on our future business and operations. For a discussion of
additional pandemic-related risks to our business, see below under the heading “Risks Related to the COVID-19 Pandemic.”

If UKONIQ or any future products for which we receive regulatory approval, including U2 in CLL/SLL and ublituximab in RMS,
do  not  achieve  an  adequate  level  of  acceptance  by  physicians,  hospitals,  healthcare  payors  and  patients,  we  may  not  generate  sufficient
revenue from these products and we may not become or remain profitable, which would have a material adverse effect on our business.

We may be subject to limitations on the indicated uses or requirements to fulfill certain post-marketing requirements to the satisfaction of
regulatory authorities or may be unable to maintain marketing approval for UKONIQ or future products that we may bring to market.

Regulatory approvals for any of our product candidates may be subject to limitations on the approved indicated uses for which the
product  may  be  marketed  or  contain  requirements  for  potentially  costly  post-marketing  testing,  including  Phase  IV  clinical  trials,  and
surveillance  to  monitor  the  safety  and  efficacy  of  the  approved  product  candidate.  With  respect  to  the  FDA’s  approval  of  UKONIQ  for
relapsed or refractory MZL and FL, we received accelerated approval and are subject to certain post-approval requirements. For example, we
will need to conduct a confirmatory clinical trial, which will involve a Phase 3 trial that may be expensive and time-consuming and difficult
to complete with the time frame expected by the FDA. Moreover, the confirmatory clinical trial may not confirm the benefit making the MZL
and FL indications for UKONIQ subject to withdrawal of continued approval by the FDA or voluntary withdrawal by the Company, which
could significantly harm our business. In addition, we will need to conduct additional clinical studies to address post-marketing commitments
and  post-marketing  requirements  related  to  further  assessing  the  drug-drug  interaction  profile  of  UKONIQ  and  its  safety,  efficacy,  and
pharmacokinetic properties in certain at-risk populations. These studies are highly specialized in their design and conduct and are associated
with considerable expenses, and based on the outcome, could result in further labeling restrictions that could impair or restrict the way in
which we are able to market UKONIQ, or negatively impact its overall clinical profile.

In  addition,  with  respect  to  UKONIQ,  and  any  product  candidate  that  the  FDA  or  a  comparable  foreign  regulatory  authority
approves,  the  manufacturing  processes,  labeling,  packaging,  distribution,  import,  export,  adverse  event  reporting,  storage,  advertising,
promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. These requirements include
submissions  of  safety  and  other  post-marketing  information  and  reports,  registration,  as  well  as  continued  compliance  with  current  Good
Manufacturing Practices, or GMPs, with Good Clinical Practices, or GCPs, for any clinical trials that we conduct post-approval, and with
Good Laboratory Practices, or GLPs, for any nonclinical studies. Later discovery of previously unknown problems with a product or with our
third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things,
restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market, mandatory safety labeling changes
or  product  recalls,  suspension  or  revocation  of  product  approvals,  product  seizure  or  detention,  refusal  to  permit  the  import  or  export  of
products,  and  injunctions  or  the  imposition  of  civil  or  criminal  penalties,  all  of  which  would  adversely  affect  our  business,  prospects  and
ability to achieve or sustain profitability.

UKONIQ,  and  any  of  our  product  candidates  for  which  we  in  the  future  obtain  approval,  may  after  approval  be  found  to  cause
undesirable side effects that could result in significant negative consequences following commercialization.

As UKONIQ or any future approved products are used more widely or for a longer duration after being brought to market, data may
emerge  from  clinical  studies,  including  confirmatory  or  other  post-marketing  studies,  or  from  adverse  event  reporting  that  may  affect  the
commercial potential of our products. For example, as additional patients are exposed for longer durations to UKONIQ in the commercial
and clinical settings, it is unknown whether greater frequency and/or severity of adverse events are likely to occur or whether an acceptable
safety and tolerability profile will continue to be demonstrated. If we or others identify unexpected side effects, caused by UKONIQ or our
product candidates following introduction into the market, a number of potentially significant negative consequences could result, including:

● regulatory authorities may withdraw or limit the use (indication) of such products;
● regulatory authorities may require the addition of labeling statements, including warnings or boxed warnings, precautions, or
contraindications  that  could  diminish  the  usage  of  the  product  or  otherwise  limit  the  commercial  success  of  the  affected
product;

34

 
Table of Contents

● we may be required to change the way such drug candidates are distributed or administered, or to conduct additional clinical

trials;

● regulatory  authorities  may  require  a  Risk  Evaluation  and  Mitigation  Strategy  (REMS),  a  plan  to  mitigate  risks,  which  could
include  a  Medication  Guide,  physician  communication  plans,  or  elements  to  assure  safe  use,  such  as  restricted  distribution
methods, patient registries and other risk minimization tools;

● we may be subject to regulatory investigations and government enforcement actions;
● we may decide to remove such drug candidates from the marketplace;
● we may not be able to enter into collaboration agreements on acceptable terms and execute on our business model;
● we could be sued and held liable for injury caused to individuals exposed to or taking our products; and
● our reputation may suffer.

Any  one  or  a  combination  of  these  events  could  prevent  us  from  maintaining  regulatory  approval  and  achieving  or  maintaining
market  acceptance  of  the  affected  product  or  could  substantially  increase  the  costs  and  expenses  of  commercializing  the  affected  product,
which in turn could significantly impact our ability to successfully commercialize our drug candidates and generate revenues.

The  incidence  and  prevalence  for  target  patient  populations  of  UKONIQ  and  our  product  candidates,  including  U2  in  CLL/SLL  and
ublituximab in RMS, have not been established with precision. If the market opportunities for UKONIQ and our product candidates are
smaller than we estimate or if any approval that we obtain is based on a narrower definition of the patient population, our revenue and
ability to achieve profitability will be adversely affected, possibly materially.

The  precise  incidence  and/or  prevalence  of  R/R  MZL  after  one  prior  anti-CD20-based  regimen,  R/R  FL  after  three  prior  lines  of
systemic  therapy,  CLL,  and  RMS  are  unknown.  Our  projections  of  both  the  number  of  patients  within  our  FDA-approved  indications  for
UKONIQ and target indications for U2 in CLL/SLL and ublituximab in RMS, as well as the subset of these patients who have the potential to
benefit from treatment with our products, are based on estimates. These estimates are typically based on one on one and group interactions
with target physicians and other sources available at the time we make the estimates, including the scientific literature, healthcare utilization
databases and market research. Although we believe our estimates are reasonable, many factors may limit their accuracy. For example, the
sources we use to make the estimates may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of
these diseases and the number of patients may turn out to be lower than expected.

The total addressable market opportunity for UKONIQ in MZL and FL, U2 in CLL/SLL, and ublituximab in RMS will ultimately
depend  upon,  among  other  things,  the  scope  of  the  final  approved  indication  and  other  elements  of  the  approved  prescribing  information,
acceptance  by  the  medical  community,  patient  access,  and  drug  pricing  and  reimbursement.  The  number  of  patients  in  major  markets,
including  the  number  of  addressable  patients  in  those  markets,  may  turn  out  to  be  lower  than  expected,  patients  may  not  be  otherwise
amenable to treatment with our drugs, new patients may become increasingly difficult to identify or gain access to, or patients and physicians
may choose to utilize competitive products, all of which would adversely affect our results of operations and our business.

We face substantial competition, which may result in others commercializing drugs before or more successfully than we do resulting in
the reduction or elimination of our commercial opportunity.

We  operate  in  a  highly  competitive  segment  of  the  biotechnology  and  biopharmaceutical  market.  We  face  competition  from
numerous  sources,  including  commercial  pharmaceutical  and  biotechnology  enterprises,  academic  institutions,  government  agencies,  and
private and public research institutions. Many of our competitors have significantly greater financial, product development, manufacturing
and  commercialization  resources.  Large  pharmaceutical  companies  have  extensive  experience  in  clinical  testing  and  obtaining  regulatory
approval  for  drugs.  Additionally,  many  universities  and  private  and  public  research  institutes  are  active  in  cancer  research,  some  in  direct
competition with us. We may also compete with these organizations to recruit scientists and clinical development personnel. Smaller or early-
stage  companies  may  also  prove  to  be  significant  competitors,  particularly  through  collaborative  arrangements  with  large  and  established
companies.

35

 
 
 
 
Table of Contents

Our  commercial  opportunity  could  be  reduced  or  eliminated  if  our  competitors  develop  and  commercialize  drugs  that  are  more
effective, have fewer or less severe side effects, are more convenient or are priced or contracted differently than any drugs that we or our
collaborators  may  develop.  Our  competitors  also  may  obtain  FDA  or  other  regulatory  approval  for  their  drugs  more  rapidly  than  we  may
obtain approval for ours, which could result in our competitors establishing a strong market position before we or our collaborators are able to
enter the market. In a competitive environment, a company’s communications may also be subject to heightened scrutiny from regulators and
competitors,  under  laws,  regulations,  and  guidance  about  promotional  communications  (advertising  and  promotional  labeling)  and  non-
promotional communications (e.g., certain educational and scientific exchange); and with regard to potential competitor actions under federal
law (the Lanham Act) and congruous state law, which protect businesses against the unfair competition of misleading advertising or labeling.

The key competitive factors affecting the success of all of our drug candidates, if approved, are likely to be their efficacy, safety,

convenience, price, the level of generic competition and the availability of reimbursement from government and other third-party payors.

New developments, including the development of other pharmaceutical technologies and methods of treating disease, occur in the
pharmaceutical  and  life  sciences  industries  at  a  rapid  pace.  These  developments  may  render  our  product  candidates  obsolete  or
noncompetitive. Compared to us, many of our potential competitors have substantially greater:

● research and development resources, including personnel and technology;
● regulatory experience;
● pharmaceutical development, clinical trial and pharmaceutical commercialization experience;
● experience and expertise in exploitation of intellectual property rights; and
● capital resources.

We will also face competition from these third parties in recruiting and retaining qualified personnel, establishing clinical trial sites,

patient registration for clinical trials, and in identifying and in-licensing new product candidates.

UKONIQ, as well as any products that we are able to commercialize in the future, may become subject to unfavorable pricing regulations
or third-party payor coverage and reimbursement policies, which would harm our business.

The regulations that govern regulatory approvals, pricing and reimbursement for new drugs vary widely from country to country.
Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins
after marketing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental
control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular country, but then be
subject to price regulations that delay our commercial launch of the drug candidate, possibly for lengthy time periods, and negatively impact
the revenues we are able to generate from the sale of the drug candidate in that country. Adverse pricing limitations may hinder our ability to
recoup our investment in one or more products, even if our product candidates obtain marketing approval. Eligibility for reimbursement does
not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and
distribution. Interim reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made
permanent. In addition, if we are successful in obtaining FDA approval for ublituximab for the treatment of CLL/SLL and RMS, we will
need to identify and execute a pricing strategy that takes into account the value of the product in each indication independently to realize the
product’s  full  potential  in  both  indications.  If  we  are  unable  to  identify  and  execute  such  a  strategy,  the  pricing  of  ublituximab  across
indications may not be optimal, which may have a material adverse impact on the sales in one or both of the indications and on our overall
business.

Our ability to commercialize any product successfully also will depend in part on the extent to which coverage and reimbursement
for  our  products  and  related  treatments  will  be  available  from  government  authorities,  private  health  insurers  and  other  organizations.
Government  authorities  and  third-party  payors,  such  as  private  health  insurers  and  health  maintenance  organizations,  decide  which
medications  they  will  pay  for  and  establish  reimbursement  and  co-payment  levels.  A  primary  trend  in  the  U.S.  healthcare  industry  and
elsewhere  is  cost  containment.  Government  authorities  and  third-party  payors  have  attempted  to  control  costs  by  restricting  coverage  and
limiting the amount of reimbursement for particular drugs. Increasingly, third-party payors are requiring that drug companies provide them
with predetermined discounts from list prices and are challenging the prices charged for drugs, examining the cost effectiveness of drugs in
addition to their safety and efficacy. Third-party commercial payors often rely upon Medicare coverage policy and payment limitations in
setting  their  own  reimbursement  policies.  Payors  may  restrict  coverage  of  some  products  by  using  formularies  under  which  only  selected
drugs  are  covered,  variable  co-payments  that  make  drugs  that  are  not  preferred  by  the  payor  more  expensive  for  patients,  and  utilization
management controls, such as requirements for prior authorization or failure first on another type of treatment. Payors may target higher-

36

 
 
 
 
 
 
Table of Contents

priced  drugs  for  imposition  of  these  obstacles  to  coverage,  and  consequently  our  products  may  be  subject  to  payer-driven  restrictions.
Additionally, in countries where patients have access to insurance, as in the U.S., insurance co-payment amounts or other benefit limits may
represent  a  barrier  to  obtaining  or  continuing  use  of  our  products  that  receive  regulatory  approval.  If  we  are  unable  to  obtain  or  maintain
coverage, or coverage is reduced in one or more countries, our product sales may be lower than anticipated and our financial condition could
be harmed.

Net  prices  for  drugs  may  be  reduced  by  mandatory  discounts  or  rebates  required  by  government  healthcare  programs  or  private
payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices. In
the United States, for example, we must offer discounted pricing or rebates on purchases of pharmaceutical products under various federal
and state healthcare programs, such as the Medicaid Drug Rebate Program, the 340B drug pricing program and the Medicare Part D Program.
We  must  also  report  specific  prices  to  government  agencies  under  healthcare  programs,  such  as  the  Medicaid  Drug  Rebate  Program  and
Medicare  Part  B.  The  calculations  necessary  to  determine  the  prices  reported  are  complex  and  the  failure  to  report  prices  accurately  may
expose us to penalties. 

If, in the future, we are unable to expand our commercial operations, including sales and marketing capabilities or enter into agreements
with  third  parties  to  sell  and  market  our  drug  candidates,  we  may  not  be  successful  in  commercializing  our  product  candidates  if  and
when they are approved, and we may not be able to generate any revenue.

We have made and continue to make significant investments in our commercial organization and infrastructure. We have hired and
continue to hire marketing, sales, and medical support personnel and have built processes and systems to support the commercialization of
UKONIQ in the U.S. We are expanding our commercialization team and infrastructure in planning for the potential commercial launches of
U2 in CLL/SLL and ublituximab in RMS prior to knowing whether the FDA will accept or approve the necessary regulatory submissions. It
is possible that either or both FDA approvals are unexpectedly delayed or are not received at all. For example, in November 2021, the FDA
notified the Company that it planned to discuss the benefit-risk profile of U2 in CLL/SLL as well as UKONIQ in the approved indications
during an ODAC meeting to be held in March or April 2022. Given the timing of the ODAC, the Company anticipates it is unlikely that the
FDA will make a decision on the BLA/sNDA by the PDUFA goal date of March 25, 2022. See “Risks Related to the Development and
Commercialization  of  U2  and  UKONIQ.”  A  significant  delay  in  regulatory  approval  will  cause  us  to  incur  delays  that  may  impede  or
significantly delay our ability to generate revenue while incurring significant expenses, which would have a material adverse effect on the
Company.

There  are  risks  involved  with  establishing  our  own  sales,  marketing,  and  other  commercialization  capabilities.  For  example,
recruiting and training a sales force is both expensive and time-consuming, and could potentially delay any drug launch. If the commercial
launch  of  a  product  candidate  (e.g.,  U2  in  CLL/SLL  or  ublituximab  in  MS)  for  which  we  recruit  a  sales  force  and  establish  marketing
capabilities  is  delayed  or  does  not  occur  for  any  reason,  we  would  have  prematurely  or  unnecessarily  incurred  these  commercialization
expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel.

Factors  that  may  inhibit  our  efforts  to  commercialize  UKONIQ  and  our  product  candidates  on  our  own  and  generate  product

revenues include:

● our inability to recruit and retain adequate numbers of effective sales and marketing personnel;
● the costs and time associated with the initial and ongoing training of sales and marketing personnel on the applicable disease

states, products, competitors, and legal and regulatory compliance matters;

● the inability of sales personnel to obtain access to physicians or to effectively promote UKONIQ or any future drugs;
● the lack of complementary drugs to be offered by sales personnel, which may put us at a competitive disadvantage relative to

companies with more extensive product lines;

● our ability to maintain a healthcare compliance program including effective mechanisms for compliance monitoring; and
● unforeseen costs and expenses associated with creating a sales and marketing organization.

In the future, we may choose to participate in sales activities with collaborators for some of our product candidates if and when they
are approved. However, there are also risks with entering into these types of arrangements with third parties to perform sales, marketing and
distribution services. For example, we may not be able to enter into such arrangements on terms that are favorable to us. Our drug revenues or
the profitability of these drug revenues to us are likely to be lower than if we were to market and sell any product candidates that we develop
ourselves. In addition, we likely will have little control over such third parties, and any of them may fail to devote the necessary resources
and attention to sell and market our product candidates effectively. If we do not establish sales and marketing capabilities

37

 
 
 
 
 
Table of Contents

successfully,  either  on  our  own  or  in  collaboration  with  third  parties,  we  will  not  be  successful  in  commercializing  our  drug  candidates.
Further, our business, results of operations, financial condition and prospects will be materially adversely affected.

We  are  also  planning  for  expansion  into  certain  European  markets.  Building  and  maintaining  an  infrastructure  outside  the  United
States is expensive, complex, resource intensive and time consuming. Like the situation described above in the U.S., we will need to establish
our infrastructure in planning for potential commercial launches in Europe prior to knowing whether the regulatory authorities will accept or
approve  our  regulatory  submissions  or  approve  any  of  our  products  at  an  appropriate  price.  In  either  case  we  will  incur  delays  that  may
impede  or  significantly  delay  our  ability  to  generate  revenue  in  those  international  markets  and  at  the  same  time  will  incur  significant
expenses. If this were to occur, it could materially and adversely affect our business operations and financial condition.

Product  liability  lawsuits  against  us  could  cause  us  to  incur  substantial  liabilities  and  could  limit  commercialization  of  any  drug
candidates that we may develop.

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials, and an
even  greater  risk  in  connection  with  the  commercialization  of  UKONIQ  and  any  other  product  candidates  for  which  we  may  receive
marketing  authorization  in  the  future.  If  we  cannot  successfully  defend  ourselves  against  claims  that  UKONIQ  or  our  product  candidates
caused injuries, we could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

● decreased demand for any products that we may commercialize;
● injury to our reputation and significant negative media attention;
● withdrawal of clinical trial participants;
● significant costs to defend the related litigation;
● substantial monetary awards to trial participants or patients;
● loss of revenue; and
● the inability to commercialize any product candidates that we may develop.

Although  we  maintain  product  liability  insurance  coverage,  it  may  not  be  adequate  to  cover  all  liabilities  that  we  may  incur.
Insurance  coverage  is  increasingly  expensive.  We  may  not  be  able  to  maintain  insurance  coverage  at  a  reasonable  cost  or  in  an  amount
adequate to satisfy any liability that may arise.

Risks Related to Our Financial Position and Need for Additional Capital

We have incurred significant operating losses since our inception and anticipate that we will incur continued losses for the foreseeable
future.

Biopharmaceutical drug development is a highly speculative undertaking and involves a substantial degree of risk. We commenced
operations in January 2012. Our operations to date have been limited primarily to organizing and staffing our company, business planning,
raising  capital,  developing  our  technology,  identifying  potential  drug  candidates,  undertaking  pre-clinical  studies  and  clinical  trials,
commercializing  our  only  marketed  product  UKONIQ,  which  received  FDA  approval  in  February  2021,  and  preparing  for  potential
commercialization  of  ublituximab.  We  are  transitioning  from  a  company  with  a  research  and  development  focus  to  a  company  capable  of
supporting commercial activities, potentially across hematology and neurology as well as in the U.S. and outside the U.S. We may not be
successful in such a transition.

Since inception, we have focused our efforts and financial resources on clinical trials, manufacturing of our drug candidates, and
preparing to support a commercial product. To date, we have financed our operations primarily through public offerings of our common stock
and a debt financing. Since inception, we have incurred significant operating losses. Substantially all our operating losses have resulted from
costs incurred in connection with our research and development programs and from selling, general and administrative costs associated with
our operations, including our commercialization activities. We expect to continue to incur significant expenses and operating losses for the
foreseeable  future.  Our  prior  losses,  combined  with  expected  future  losses,  have  had  and  will  continue  to  have  an  adverse  effect  on  our
stockholders’ deficit and working capital. Other than the FDA approval of UKONIQ, we have not obtained marketing approval for any of our
product  candidates,  which  are  in  preclinical  or  clinical  development  stages.  We  expect  to  continue  to  incur  significant  research  and
development expenses in connection with continuing our existing clinical trials and beginning additional clinical trials. In addition, we expect
to  continue  to  incur  significant  sales,  marketing  and  outsourced-manufacturing  expenses  as  we  commercialize  UKONIQ  and  plan  for  the
possible commercialization of ublituximab in CLL/SLL and RMS, if approved. Because of the numerous risks and uncertainties associated

38

 
 
 
 
Table of Contents

with developing pharmaceuticals, we are unable to predict the extent of any future losses or when we will become profitable, if at all. Even if
we do become profitable, we may not be able to sustain or increase our profitability on a quarterly or annual basis. Our ability to become
profitable depends upon our ability to generate substantial revenue.

To date, we have not generated any significant revenue from our product sales, and it is uncertain when and if we will generate any
significant revenue from the sale of our products in the future. Furthermore, no assurance can be given that we will meet revenue projections
or guidance. To obtain significant and sustained revenues and meet our revenue projections or guidance, we must succeed, either alone or
with  others,  in  (i)  developing  and  obtaining  regulatory  approval  for  our  product  candidates,  including  ublituximab,  and  for  additional
indications  of  UKONIQ;  and  (ii)  manufacturing  and  marketing  our  products  and  product  candidates.  Accordingly,  we  do  not  expect  to
generate  significant  and  sustained  revenue  unless  and  until  we  obtain  marketing  approval  of  ublituximab  and  additional  indications  of
UKONIQ and/or one of our other product candidates. Our ability to generate significant and sustained revenue or meet revenue projections or
guidance depends on a number of factors, including, but not limited to, our ability to:

● successfully complete clinical trials that meet their clinical endpoints;
● initiate and successfully complete all safety, pharmacokinetic, biodistribution, and non-clinical studies required to obtain U.S.

and foreign marketing approval for our product candidates;

● obtain approval from the FDA and foreign equivalents to market and sell our product candidates, including ublituximab in CLL

/SLL and RMS, and maintain FDA approval of UKONIQ for relapsed or refractory MZL and FL;

● establish  commercial  manufacturing  capabilities  with  third  parties  that  are  satisfactory  to  the  regulatory  authorities,  cost
effective, and that are capable of providing commercial supply of our product candidates, or, in the case of UKONIQ, maintain
these capabilities;

● expand  on  our  commercial  infrastructure  to  commercialize  ublituximab,  our  other  product  candidates,  and  additional
indications  of  UKONIQ,  if  approved,  by  increasing  the  size  of  our  sales  force  and  commercialization  infrastructure  and/or
entering into collaborations with third parties; and

● achieve  market  acceptance  of  UKONIQ  and  our  product  candidates,  if  approved,  in  the  medical  community  and  with  third-

party payors.

If we are unable to generate significant and sustained revenues, we will not become profitable and we will be unable to continue our

operations without continued funding.

We will need to raise substantial additional funding. If we are unable to raise capital when needed, we would be forced to delay, reduce or
eliminate some of our drug development programs or commercialization efforts.

The  development  of  pharmaceuticals  is  capital-intensive.  We  are  currently  advancing  our  most  advanced  drug  candidates,
ublituximab,  cosibelimab,  TG-1701  and  TG-1801,  and  UKONIQ  for  additional  indications  through  clinical  development.  While  we  may
experience short-term decreases in clinical trial expenses as our larger Phase 3 clinical trials complete and before our Phase 1 and 2 programs
can  advance  into  Phase  2  and  3,  we  do  expect  over  time  our  overall  expenses  will  increase  in  connection  with  our  ongoing  activities,
particularly as we continue the research and development of, initiate or continue clinical trials of, seek marketing approval for, and expand
our  infrastructure  to  commercialize  our  product  candidates  and  additional  indications  of  UKONIQ.  Moreover,  in  anticipation  of  potential
regulatory approvals for UKONIQ and ublituximab in CLL/SLL and for ublituximab in RMS, we will need to expend substantial resources
on BLA support, including preparation for the ODAC meeting on U2 in CLL and SLL over the next 6 to 12 months, and on manufacturing
support over the next 12 to 18 months, which could exceed any cost savings associated with lower clinical trial expenses during the same
period.

While this timing is our current estimate, the amount and timing of our future funding requirements will depend on many factors,

including, but not limited to, the following:

● the progress of our clinical trials, including expenses to support the trials and milestone payments that may become payable

under our license agreements;

● developments relating to the COVID-19 pandemic in the U.S. and around the world;
● the costs and timing of regulatory approvals;
● the costs and timing of clinical and commercial manufacturing supply arrangements for each product and product candidate;
● the costs of expanding our sales, distribution, and other commercialization capabilities;

39

 
 
 
 
Table of Contents

● the success of the commercialization of UKONIQ and any product candidates, if approved;
● our ability to establish and maintain strategic collaborations, including licensing and other arrangements;
● the costs involved in enforcing or defending patent claims or other intellectual property rights; and
● the extent to which we in-license or invest in other indications or product candidates.

As a result, significant additional funding will be required. Additional sources of financing to continue our operations in the future
might not be available on favorable terms, if at all. If we do not succeed in raising additional funds on acceptable terms, we might be unable
to complete planned preclinical studies and clinical trials or obtain approval of any of our product candidates from the FDA or any foreign
regulatory authorities. In addition, we could be forced to discontinue product development, reduce or forego sales, marketing and medical
educational efforts that are required for successful commercialization of UKONIQ, ublituximab (if approved), or any of our other product
candidates and otherwise forego attractive business opportunities. Any additional sources of financing will likely involve the issuance of our
equity securities, which would have a dilutive effect to stockholders. Currently, other than UKONIQ, our products are investigational and
have not been approved by the FDA or any foreign regulatory authority for sale. Therefore, for the foreseeable future, we will have to fund all
of  our  operations  and  capital  expenditures  from  sales  of  UKONIQ  in  the  U.S.,  cash  on  hand  and  amounts  raised  in  future  offerings  or
financings. Accordingly, our prospects must be considered in light of the uncertainties, risks, expenses and difficulties frequently encountered
by companies in the early stages of commercial operations and the competitive environment in which we operate.

Raising  additional  capital  may  cause  dilution  to  our  stockholders,  restrict  our  operations  or  require  us  to  relinquish  rights  to  our
technologies or drug candidates and occupy valuable management time and resources.

Until such time, if ever, as we can generate substantial drug revenues, we expect to finance our cash needs through a combination of
public  and  private  equity  offerings,  debt  financings,  collaborations,  strategic  alliances  and  licensing  arrangements.  We  do  not  have  any
committed  external  source  of  funds,  other  than  funds  already  borrowed  under  the  loan  and  security  agreement  that  we  entered  into  with
Hercules  in  February  2019,  and  which  was  expanded  in  December  2021  (see  Note  6  to  our  consolidated  financial  statements  for  more
information). To the extent that we raise additional capital through the sale of common stock or securities convertible or exchangeable into
common stock, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other
preferences that materially adversely affect the rights of our common stockholders. We may also seek funds through collaborations, strategic
alliances or licensing arrangements with third parties at a time that is not desirable to us and we may be required to relinquish valuable rights
to  some  intellectual  property,  future  revenue  streams,  research  programs  or  drug  candidates  or  to  grant  licenses  on  terms  that  may  not  be
favorable to us, any of which may have a material adverse effect on our business, operating results and prospects. Debt financing, if available,
may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt,
making capital expenditures or declaring dividends. See our risk factors below under the heading “Risks Related to Our Indebtedness.”

Additionally, fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability
to develop and commercialize our drug candidates. Dislocations in the financial markets have generally made equity and debt financing more
difficult  to  obtain  and  may  have  a  material  adverse  effect  on  our  ability  to  meet  our  fundraising  needs.  We  cannot  guarantee  that  future
financing  will  be  available  in  sufficient  amounts  or  on  terms  acceptable  to  us,  if  at  all.  Moreover,  the  issuance  of  additional  securities,
whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our shares to decline.

Long-term commercialization and product candidate development timelines and projections in this report are based on the assumption of
further financing.

The timelines and projections in this report are predicated upon the assumption that we will raise additional financing in the future to
continue our long-term commercialization efforts and the development of our product candidates. In the event we do not successfully raise
subsequent financing, such commercialization and product development activities may be curtailed commensurate with the magnitude of the
shortfall. If our commercialization or product development activities are slowed or stopped, we would be unable to meet the timelines and
projections  outlined  in  this  filing.  Failure  to  progress  our  commercialization  activities  or  the  development  of  our  product  candidates  as
anticipated will have a negative effect on our business, future prospects, and ability to obtain further financing on acceptable terms, if at all,
and the value of the enterprise.

Due to limited resources we may fail to capitalize on programs or product candidates that may present a greater commercial opportunity
or for which there is a greater likelihood of success.

Because we have limited resources, we may forego or delay pursuit of opportunities with certain programs or product candidates or
for  indications  that  later  prove  to  have  greater  commercial  potential.  Our  estimates  regarding  the  potential  market  for  a  product  candidate
could  be  inaccurate,  and  our  spending  on  current  and  future  research  and  development  programs  may  not  yield  any  commercially  viable
products. If we do not accurately evaluate the commercial potential for a particular product candidate, we may relinquish valuable rights to
that  product  candidate  through  strategic  collaboration,  licensing  or  other  arrangements  in  cases  in  which  it  would  have  been  more
advantageous  for  us  to  retain  sole  development  and  commercialization  rights  to  such  product  candidate.  Alternatively,  we  may  allocate
internal  resources  to  a  product  candidate  in  a  therapeutic  area  in  which  it  would  have  been  more  advantageous  to  enter  into  a  partnering
arrangement.

If  any  of  these  events  occur,  we  may  be  forced  to  abandon  or  delay  our  development  efforts  with  respect  to  a  particular  product
candidate or fail to develop a potentially successful product candidate, which could have a material adverse effect on our business, financial
condition, results of operations and prospects.

Our level of indebtedness and debt service obligations could adversely affect our financial condition and may make it more difficult for us
to fund our operations.

In February 2019, we entered into a Loan and Security Agreement (the Loan Agreement), with Hercules Capital, Inc., a Maryland
corporation (Hercules) and on December 30, 2021 (the First Amendment Closing Date), the Company entered into an Amended and Restated
Loan and Security Agreement (the Amended Loan Agreement) with Hercules. Under the Amended Loan Agreement, Hercules increased the
aggregate principal amount of the loan, available at the Company’s option, from $60.0 million to $200.0 million (the Amended Term Loan)
(see  Note  6  to  our  consolidated  financial  statements  for  more  information).  A  first  advance  of  $70.0  was  million  drawn  at  the  First
Amendment Closing Date, a portion of which was used to refinance the current outstanding loan balance of approximately $7.8 million.

All obligations under the Amended Loan Agreement are secured by substantially all of our existing property and assets, excluding
intellectual property. This indebtedness may create additional financing risk for us, particularly if our business or prevailing financial market
conditions  are  not  conducive  to  paying  off  or  refinancing  its  outstanding  debt  obligations  at  maturity.  This  indebtedness  could  also  have
important negative consequences, including:

● we will need to repay the indebtedness by making payments of interest and principal, which will reduce the amount of money

available to finance our operations, our research and development efforts and other general corporate activities; and

● our failure to comply with the restrictive covenants in the Amended Loan Agreement could result in an event of default that, if
not cured or waived, would accelerate our obligation to repay this indebtedness, and Hercules could seek to enforce its security
interest in the assets securing such indebtedness.

To the extent additional debt is added to our current debt levels, the risks described above could increase.

We may not have cash available in an amount sufficient to enable us to make interest or principal payments on our indebtedness when
due.

Failure to satisfy our current and future debt obligations under the Amended Loan Agreement, or the breach of any of its covenants,
subject to specified cure periods with respect to certain breaches, could result in an event of default and, as a result, Hercules could accelerate
all of the amounts due. In the event of an acceleration of amounts due under the Amended Loan Agreement as a result of an event of default,
we may not have enough available cash or be able to raise additional funds through equity or debt financings to repay such indebtedness at
the  time  of  such  acceleration.  In  that  case,  we  may  be  required  to  delay,  limit,  reduce  or  terminate  our  product  candidate  development  or
commercialization efforts or grant to others rights to develop and market product candidates that we would otherwise prefer to develop and
market ourselves. Hercules could also exercise its rights as collateral agent to take possession and dispose of the collateral securing the Term
Loan  for  its  benefit,  which  collateral  includes  substantially  all  of  our  property  other  than  intellectual  property.  Our  business,  financial
condition and results of operations could be materially adversely affected as a result of any of these events.

41

The Amended Loan Agreement imposes operating and other restrictions on the Company. Such restrictions will affect, and in many

respects limit or prohibit, our ability and the ability of any future subsidiary to, among other things: 

● dispose of certain assets;
● change its lines of business;
● engage in mergers, acquisitions or consolidations;
● incur additional indebtedness;
● create liens on assets;
● pay dividends and make contributions or repurchase our capital stock; and
● engage in certain transactions with affiliates.

The breach of any of these restrictive covenants could have a material adverse effect on our business and prospects.

Risks Related to Drug Development and Regulatory Approval

If we are unable to obtain regulatory approval for our product candidates and ultimately cannot commercialize one or more of them, or
experience significant delays in doing so, our business will be materially harmed.

We  have  invested  substantially  all  of  our  efforts  and  financial  resources  in  the  identification  and  pre-clinical  and  clinical
development  of  UKONIQ  and  our  product  candidates,  including  ublituximab,  cosibelimab,  TG-1701  and  TG-1801,  and  building  a
commercial infrastructure. Our ability to generate revenues from product sales will depend completely on the successful completion of our
current  and  future  Phase  3  and  registration-directed  clinical  trials  and  commercialization  of  our  product  candidates,  including  ublituximab
and additional indications of UKONIQ, which may never occur. Each of our product candidates will require additional non-clinical or clinical
development, regulatory approval in multiple jurisdictions, and we will need to obtain sufficient clinical and commercial supply. The success
of our development programs and achievement of regulatory approval of our product candidates will depend on several factors, including the
following:

● successful completion of our clinical programs with positive results that support a finding of effectiveness and an acceptable

safety profile of our product candidates in the intended populations within the timeframes we have projected;

● INDs and clinical trial applications, or CTAs, being cleared/approved such that our product candidates can commence clinical

trials;

● successful initiation and completion of preclinical studies and successful initiation of, enrollment in and completion of clinical

trials;

● sufficiency of our financial and other resources to complete the necessary preclinical studies and clinical trials;
● receipt  of  regulatory  approvals  from  applicable  regulatory  authorities  for  our  product  candidates,  including  U2  in  CLL  and

ublituximab in RMS;

● establishing  commercially  viable  arrangements  with  third-party  manufacturers  for  clinical  supply  and  commercial

manufacturing; and

● obtaining and maintaining patent and trade secret protection or regulatory exclusivity for our product candidates.

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays in our clinical

programs and regulatory submission timelines and may not be able to obtain regulatory approval for our product candidates.

Because results of preclinical studies and early clinical trials are not necessarily predictive of future results, any product candidate we
advance  may  not  have  favorable  results  in  later  clinical  trials  or  receive  regulatory  approval.  Moreover,  interim,  “top-line,”  and
preliminary  data  from  our  clinical  trials  that  we  announce  or  publish  may  change,  or  the  perceived  product  profile  may  be  negatively
impacted, as more patient data or additional endpoints (including efficacy and safety) are analyzed.

Pharmaceutical development has inherent risks. The outcome of preclinical development testing and early clinical trials may not be
predictive  of  the  outcome  of  later  clinical  trials,  and  interim  results  of  a  clinical  trial  do  not  necessarily  predict  final  results.  Moreover,
preclinical  and  clinical  data  are  often  susceptible  to  varying  interpretations  and  analyses,  and  many  companies  that  have  believed  their
product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of
their  product  candidates.  Once  a  product  candidate  has  displayed  sufficient  preclinical  data  to  warrant  clinical  investigation,  we  will  be
required to demonstrate through adequate and well-controlled clinical trials that our product candidates are effective with a favorable benefit-

42

risk profile for use in populations for their target indications before we can seek regulatory approvals for their commercial sale. Many drug
candidates  fail  in  the  early  stages  of  clinical  development  for  safety  and  tolerability  issues  or  for  insufficient  clinical  activity,  despite
promising pre-clinical results. Accordingly, no assurance can be made that a safe and efficacious dose can be found for these compounds or
that  they  will  ever  enter  into  advanced  clinical  trials  alone  or  in  combination  with  other  product  candidates.  Moreover,  success  in  early
clinical  trials  does  not  mean  that  later  clinical  trials  will  be  successful  because  product  candidates  in  later-stage  clinical  trials  may  fail  to
demonstrate  sufficient  safety  or  efficacy  despite  having  progressed  through  initial  clinical  testing.  Companies  frequently  experience
significant setbacks in advanced clinical trials, even after earlier clinical trials have shown promising results. There is an extremely high rate
of failure of pharmaceutical candidates proceeding through clinical trials.

Individually  reported  outcomes  of  patients  treated  in  clinical  trials  may  not  be  representative  of  the  entire  population  of  treated
patients in such studies. In addition, larger scale Phase 3 studies, which are often conducted internationally, are inherently subject to increased
operational risks compared to earlier stage studies, including the risk that the results could vary on a region to region or country to country
basis,  which  could  materially  adversely  affect  the  outcome  of  the  study  or  the  opinion  of  the  validity  of  the  study  results  by  applicable
regulatory agencies.

From time to time, we may publicly disclose top-line or preliminary data from our clinical trials, which is based on a preliminary
analysis of then available data, and the results and related findings and conclusions are subject to change following a more comprehensive
review of the data related to the particular study or trial. We also make assumptions, estimations, calculations and conclusions as part of our
analyses of such data, and we may not have received or had the opportunity to fully and carefully evaluate all data from the particular study
or trial, including all endpoints and safety data. As a result, top-line or preliminary results that we report may differ from future results of the
same studies, or different conclusions or considerations may qualify such results once additional data have been received and fully evaluated.
Top-line  or  preliminary  data  also  remain  subject  to  audit  and  verification  procedures  that  may  result  in  the  final  data  being  materially
different  from  the  topline,  interim,  or  preliminary  data  we  previously  published.  When  providing  top-line  results,  we  may  disclose  the
primary endpoint of a study before all secondary endpoints have been fully analyzed. A positive primary endpoint does not translate to all, or
any, secondary endpoints being met. As a result, top-line and preliminary data should be viewed with caution until the final data are available,
including data from the full safety analysis and the final analysis of all endpoints.

Further,  from  time  to  time,  we  may  also  disclose  interim  data  from  our  preclinical  studies  and  clinical  trials.  Interim  data  from
clinical  trials  that  we  may  complete  are  subject  to  the  risk  that  one  or  more  of  the  clinical  outcomes  may  materially  change  as  patient
enrollment  continues  and  more  patient  data  become  available.  For  example,  time-to-event  based  endpoints  such  as  duration  of  response
(DOR) and PFS have the potential to change, sometimes drastically, with longer follow-up. In addition, as patients continue on therapy, there
can be no assurance given that the final safety data from studies, once fully analyzed, will be consistent with prior safety data presented, will
be  differentiated  from  other  similar  agents  in  the  same  class,  will  support  continued  development,  or  will  be  favorable  enough  to  support
regulatory approvals for the indications studied. Further, others, including regulatory agencies, may not accept or agree with our assumptions,
estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of
the particular program, the approvability or commercialization of the particular product candidate or product and our company in general.
The  information  we  choose  to  publicly  disclose  regarding  a  particular  study  or  clinical  trial  is  based  on  what  is  typically  extensive
information, and regulators or others may not agree with what we determine is material or otherwise appropriate information to include in our
disclosure. If the interim, top-line or preliminary data that we report differ from final results, or if others, including regulatory authorities,
disagree with the conclusions we have reached, our ability to obtain approval for, or successfully commercialize, our product candidates may
be harmed, which could harm our business, operating results, prospects or financial condition.

Many of the results reported in our early clinical trials rely on local investigator-assessed efficacy outcomes which may be subject to
greater variability or subjectivity than results assessed in a blinded, independent, centrally reviewed manner, often required of later phase,
adequate  and  well-controlled  registration-directed  clinical  trials.  If  the  results  from  our  registration-directed  trials  are  different  from  the
results  found  in  the  earlier  studies,  we  may  need  to  terminate  or  revise  our  clinical  development  plan,  which  could  extend  the  time  for
conducting our development program and could have a material adverse effect on our business.

Clinical  drug  development  involves  a  lengthy  and  expensive  process,  with  an  uncertain  outcome.  We  may  incur  additional  costs  or
experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates.

Before  obtaining  marketing  approval  from  regulatory  authorities  for  the  sale  of  any  product  candidate,  we  must  complete  pre-
clinical studies and then conduct extensive clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Clinical
testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. It is impossible to
predict  when  or  if  our  product  candidates  will  prove  effective  and  safe  in  humans  or  will  receive  regulatory  approval  or  will  have  a
differentiated safety and tolerability profile. A failure of one or more clinical trials can occur at any stage of testing. Accordingly, our ongoing
trials and future clinical trials may not be successful. Even if our clinical trials produce positive results, there can be no guarantee that the
positive outcomes will be replicated in future studies either within the same indication as previously evaluated or in alternate indications and
settings.

Successful completion of our clinical trials is a prerequisite to submitting a New Drug Application (NDA) or a BLA to the FDA and a
Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for each product candidate and, consequently, the
ultimate approval and commercial marketing of our product candidates. We do not know whether any of our ongoing or future clinical trials
for our product candidates will be completed on schedule, if at all.

Whether or not and how quickly we complete clinical trials depends in part upon the rate at which we are able to engage clinical
research/trial sites and, thereafter, the rate of enrollment of patients, and the rate at which we collect, clean, lock and analyze the clinical trial
database. Patient enrollment is a function of many factors, including the size of the patient population, the proximity of patients to clinical
sites, the eligibility criteria for the study, the existence of competitive clinical trials, and whether existing or new drugs are approved for the
indication we are studying. We are aware that other companies are currently conducting or planning clinical trials that seek to enroll patients
with the same diseases that we are studying. We may experience numerous unforeseen events, such as the COVID-19 pandemic, that could
delay or prevent our ability to complete current clinical trials, initiate new trials, receive marketing approval or commercialize our product
candidates, including:

● the  FDA  or  other  regulatory  authorities  may  require  us  to  submit  additional  data  or  impose  other  requirements  before

permitting us to initiate a clinical trial;

● the FDA or other regulatory authorities or institutional review boards (IRBs) or ethics committees (ECs) may not authorize us
or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site or in a country; we may
experience  delays  in  reaching,  or  fail  to  reach,  agreement  on  acceptable  terms  with  prospective  trial  sites  and  prospective
CROs, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial
sites;

● clinical trials of our drug candidates may produce negative or inconclusive results, and we may decide, or regulatory authorities
may  require  us,  to  conduct  additional  pre-clinical  studies  or  clinical  trials  or  we  may  decide  to  abandon  drug  development
programs;

● the number of patients required for clinical trials of our drug candidates may be larger than we anticipate, and enrollment in
these clinical trials may be slower than we anticipate or participants may drop out of these clinical trials or fail to return for
post-treatment follow-up at a higher rate than we anticipate;

● our  third-party  contractors,  including  our  clinical  trial  sites,  may  fail  to  comply  with  regulatory  requirements  or  meet  their
contractual obligations to us in a timely manner, or at all, or may deviate from the clinical trial protocol or drop out of the trial,
which may require that we add new clinical trial sites or investigators;

● we may elect to or regulatory authorities or IRBs or ECs may require that we or our investigators suspend or terminate clinical
research for various reasons, including noncompliance with regulatory requirements or a finding that the participants are being
exposed to unacceptable health risks;

● the cost of clinical trials of our product candidates may be greater than we anticipate;
● the supply or quality of our product candidates or other materials necessary to conduct clinical trials of our product candidates
may be insufficient or inadequate, including, without limitation, as a result of disruptions to our supply chains caused by the
COVID-19 pandemic and related work stoppages across the globe;

● regulatory authorities may revise the requirements for approving our product candidates, or such requirements may not be as

we anticipate; and

● our product candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators,
regulatory authorities, IRBs or ECs to suspend or terminate the trials, or reports may arise from pre-clinical or clinical testing of
other therapies in the same or a similar class that raise safety or efficacy concerns about our product candidates.

We also could encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in which such trials
are being conducted, by the DSMB for such trial or by the FDA or other regulatory authorities. Such regulatory authorities may impose a
suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements
or  our  clinical  protocols,  inspection  of  the  clinical  trial  operations  or  trial  site  by  the  FDA  or  other  regulatory  authorities  resulting  in  the
imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in
governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. For example, in January 2022,
the FDA imposed a partial clinical hold on the Company’s clinical trials investigating UKONIQ and ublituximab in CLL and NHL as a result
of concerns stemming from an initial overall survival analysis from the UNITY-CLL study that showed that a possible increased risk of death
in  patients  receiving  U2  compared  to  the  control  arm  of  obinutuzumab  plus  chlorambucil.  See  “Risks  Related  to  the  Development  and
Commercialization of U2 and UKONIQ.” In addition to the FDA, the DSMB for our clinical trials may recommend modification to the
study design or closure of the study entirely based on the DSMB’s interpretation of the benefit-risk of the study. While we develop charters
that guide the nature of the DSMB meetings, their analysis and interpretation of study data occurs independently from us and is wholly within
their control. Even if the DSMB finds no safety concerns and recommends no modifications to the ongoing study, this does not mean the
safety profile reported in the study may support a marketing approval or commercial acceptance if marketing approval is granted. Many of
the  factors  that  cause,  or  lead  to,  a  delay  in  the  commencement  or  completion  of  clinical  trials  may  also  ultimately  lead  to  the  denial  of
regulatory approval of our product candidates.

Negative or inconclusive results from the clinical trials we conduct or unanticipated adverse medical events could cause us to have
to repeat or terminate the clinical trials. If we are required to repeat or conduct additional clinical trials or other testing of our drug candidates
beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our drug candidates or other testing, if
the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, we may:

● be delayed in obtaining marketing approval for our product candidates;
● not obtain marketing approval at all;
● obtain marketing approval in some countries and not others;
● obtain approval for indications or patient populations that are not as broad as intended or desired;
● be subject to post-marketing requirements or post-marketing commitments;
● be subject to increased pricing pressure; or
● have the drug removed from the market after obtaining marketing approval.

Our drug development costs will also increase if we experience delays in testing or regulatory approvals. Certain clinical trials are
designed to continue until a pre-determined number of events have occurred in the patients enrolled. Trials such as this are subject to delays
stemming from patient withdrawal and from lower-than-expected event rates. Significant clinical trial delays could also shorten any periods
during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring products to market
before we do and impair our ability to successfully commercialize our product candidates. Any delays in our pre-clinical or future clinical
development  programs  may  harm  our  business,  financial  condition  and  prospects  significantly.  We  may  also  incur  additional  costs  if
enrollment  is  increased.  All  of  our  current  Phase  3  and  registration-directed  clinical  trials,  such  as  UNITY-CLL,  UNITY-NHL  and
ULTIMATE I and II, enrolled a larger number of patients than our initial projections, adding significant costs to those studies over and above
what had been projected.

In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and
receive  compensation  in  connection  with  such  services.  If  these  relationships  and  any  related  compensation  result  in  perceived  or  actual
conflicts of interest, the integrity of the data generated at the applicable clinical trial site, or the FDA’s willingness to accept such data, may be
jeopardized.

Our  product  candidates  may  cause  undesirable  side  effects  that  could  delay  or  prevent  their  regulatory  approval,  or  impact  their
availability and commercial potential after approval.

Unacceptable  or  undesirable  adverse  events  caused  by  any  of  our  product  candidates  that  we  take  into  clinical  trials  could  cause
either us, a DSMB, or regulatory authorities to interrupt, delay, modify or halt clinical trials and could result in a more restrictive label or the
delay or denial of regulatory approval by the FDA or other regulatory authorities. This, in turn, could prevent us from commercializing the
affected product candidate and generating revenues from its sale.

45

 
 
 
Table of Contents

As is the case with all drugs, it is likely that there will be side effects associated with the use of our drug candidates. Results of our
trials  could  reveal  a  higher  than  expected  and  unacceptable  severity  and  prevalence  of  side  effects.  In  such  an  event,  our  trials  could  be
suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny
approval of our drug candidates for any or all targeted indications. The drug-related side effects could also affect patient recruitment or the
ability of enrolled patients to complete the trial or result in potential product liability claims. In addition, data may emerge, from confirmatory
or  other  post-marketing  studies,  or  from  pharmacovigilance  reporting,  as  products  are  used  more  widely,  or  for  a  longer  duration,  after
approval that may affect the commercial potential of our products. Any of these occurrences may harm our business, financial condition and
prospects significantly. For example, as a result of concerns stemming from an initial overall survival analysis from the UNITY-CLL study
that showed that a possible increased risk of death in patients receiving U2 compared to the control arm of obinutuzumab plus chlorambucil,
the  FDA  took  a  number  of  regulatory  actions,  including  placing  selected  clinical  studies  of  U2  and  UKONIQ  on  partial  clinical  hold  and
planning an ODAC meeting to discuss the approvability of U2 in CLL and SLL and UKONIQ in R/R MZL and FL. These developments
have harmed our business and likely will continue to adversely impact our financial conditions and prospects until the FDA makes a decision
on the approvability of U2 in CLL and SLL. See “Risks Related to the Development and Commercialization of U2 and UKONIQ.”

Many  compounds  that  initially  showed  promise  in  early-stage  testing  have  later  been  found  to  cause  side  effects  that  prevented
further development of the compound. Further, early clinical trials by their nature utilize a small sample of the potential patient population.
With  a  limited  number  of  patients  and  limited  duration  of  exposure,  rare  and  serious  side  effects  of  our  drug  candidates  may  only  be
uncovered when a significantly larger number of patients are exposed to the drug candidate in Phase 3 or registration-directed trials or when
the drug candidate is on the market. If any of our product candidates cause unacceptable adverse events in clinical trials, we may not be able
to  obtain  marketing  approval  and  generate  revenues  from  its  sale,  or  even  if  approved  for  sale  may  lack  differentiation  from  competitive
products, which could have a material adverse impact on our business and operations.

Many  of  our  ongoing  and  planned  clinical  studies  involve  combinations  of  two  or  more  drugs.  In  drug  combination  clinical
development,  there  is  an  inherent  risk  of  drug-drug  interactions  between  combination  agents  that  may  affect  each  component’s  individual
pharmacologic  properties  and  the  overall  efficacy  and  safety  of  the  combination  regimen.  Both  ublituximab  and  UKONIQ  are  being
evaluated in combination with each other, as well as with a variety of other active anti-cancer agents, which may cause unforeseen toxicities,
or impact the severity, duration, and incidence of adverse events observed compared to those seen in the single-agent studies of these agents.
We  also  intend  to  explore  multiple  combination  studies  involving  cosibelimab,  TG-1701,  and  TG-1801.  Further,  with  multi-drug
combinations, it is often difficult to interpret or properly assign attribution of an adverse event to any one particular agent, introducing the
risk that toxicity caused by a component of a combination regimen could have a material adverse impact on the development of our product
candidates.  There  can  be  no  assurances  given  that  the  combination  regimens  being  studied  will  display  tolerability  or  efficacy  suitable  to
warrant further testing or produce data that is sufficient to obtain marketing approval.

Any product candidates we may advance through clinical development are subject to extensive regulation, which can be costly and time
consuming, cause unanticipated delays or prevent the receipt of the required approvals.

The  clinical  development,  manufacturing,  labeling,  packaging,  storage,  record-keeping,  advertising,  promotion,  import,  export,
marketing and distribution, and pharmacovigilance and adverse event reporting of our product candidates or any future product candidates are
subject to extensive regulation by the FDA in the United States and by comparable regulatory authorities worldwide. In the United States, we
are not permitted to market a product candidate until we receive approval of a BLA or NDA from the FDA. The process of obtaining a BLA
or  NDA  approval  is  expensive,  often  takes  many  years,  and  can  vary  substantially  based  upon  the  type,  complexity  and  novelty  of  the
products  involved.  In  addition,  approval  policies  or  regulations  may  change  over  time.  If  we  fail  to  gain  approval  to  commercialize  our
product candidates from the FDA and other foreign regulatory authorities in the timelines we project or at all, we may be unable to generate
the revenues that we may project or generate revenues at levels sufficient to sustain our business.

The FDA and foreign regulatory authorities have substantial discretion in the pharmaceutical product approval process, including the
ability  to  delay,  limit  or  deny  approval  of  a  product  candidate  for  many  reasons.  During  the  regulatory  review  process,  the  FDA  or  other
regulatory authorities may disagree with or not accept our clinical trial design, may have questions about the potential impact of our study
design on conclusions that can be drawn from the data, may interpret results differently than we do, and may change its view on the criteria
that must be met for approval. This could happen even for a protocol that has received a SPA. In September 2015, we announced a Phase 3
clinical trial for U2 for patients with CLL, which is being conducted pursuant to a SPA with the FDA (UNITY-CLL). In addition to the SPA
for UNITY-CLL, in August 2017 we announced SPAs for the ULTIMATE I and II studies evaluating ublituximab in RMS. There have been
examples of companies that have been granted SPAs and have ultimately failed to obtain final approval to market their drugs. Even if the
primary endpoint in a Phase 3 clinical trial is achieved, a SPA does not guarantee approval. In the UNITY-CLL study, the primary endpoint

46

 
 
Table of Contents

of progression-free survival was achieved, however, the FDA is planning an ODAC meeting to discuss an initial overall survival analysis,
which was not included as a secondary endpoint in the study’s statistical analysis plan. Despite the SPA and the achievement of the primary
endpoint  in  the  UNITY-CLL  study,  the  approvability  of  U2  in  CLL  and  SLL  remains  highly  uncertain.  See  “Risks  Related  to  the
Development and Commercialization of U2 and UKONIQ.”

Furthermore, some of our clinical trials may be conducted as open-label studies, meaning that trial participants, investigators, site
staff, some employees of our contract research organizations, and our field-level employees (e.g., clinical research associates and monitors),
among others, have knowledge of treatment arm assignments on a patient-level, which has the potential to introduce bias into study conduct.
Further, even when our clinical trials are double-blind, double-dummy studies, unblinding of treatment arm assignment may occur from time
to  time,  for  example,  on  the  occurrence  of  unexpected  safety  events  which  may  necessitate  understanding  of  study  treatment.  While  we
believe we have put in place adequate firewalls to prevent inappropriate unblinding of study data consistent with standard industry practice
for these types of studies, no assurance can be given that issues related to study conduct will not be raised. The FDA may raise issues of
safety,  study  conduct,  bias,  deviation  from  the  protocol,  statistical  power,  patient  completion  rates,  changes  in  scientific  or  medical
parameters or internal inconsistencies in the study design or data prior to making its final decision. The FDA may also seek the guidance of
an outside advisory committee in evaluating (among other things) clinical data and safety and effectiveness considerations prior to making its
final decision. These issues could cause a delay in the FDA’s review or lead the FDA to deny approval.

Other  reasons  that  the  FDA  or  regulatory  authorities  around  the  world  may  delay,  limit  or  deny  approval  of  a  product  candidate,

include:

● we  may  be  unable  to  demonstrate  to  the  satisfaction  of  the  FDA  or  comparable  foreign  regulatory  authorities  that  a  product

candidate is tolerable and effective for an indication;

● the FDA may not accept clinical data from trials conducted by individual investigators or in countries where the standard of

care is potentially different from that of the United States;

● the  results  of  clinical  trials  may  not  meet  the  level  of  statistical  significance  required  by  the  FDA  or  comparable  foreign

regulatory authorities for approval;

● we may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks;
● the  FDA  or  comparable  foreign  regulatory  authorities  may  disagree  with  our  interpretation  of  data  from  preclinical  studies

and/or clinical trials;

● the data collected from clinical trials of our product candidates may not be sufficient to support the submission of a BLA, NDA

or other marketing authorization submission to obtain regulatory approval in the United States or elsewhere;

● the FDA or comparable foreign regulatory authorities may not approve the manufacturing processes or facilities of third-party
manufacturers with which we or our collaborators currently contract for clinical supplies and plan to contract for commercial
supplies;

● during  the  course  of  review,  the  FDA  or  foreign  regulatory  authorities  may  raise  issues  and  request  or  require  additional
preclinical,  clinical,  chemistry,  manufacturing,  and  control  (CMC),  or  other  data  and  information,  and  the  development  and
provision of these data and information may be time consuming. We may not be able to generate the data within the time period
necessary  to  obtain  approval  within  the  established  regulatory  review  timelines,  such  as  by  a  PDUFA  goal  date  or  at  all  to
satisfy the FDA or foreign regulatory authorities;

● the  approval  policies  or  regulations  of  the  FDA  or  comparable  foreign  regulatory  authorities  may  significantly  change  in  a

manner rendering our clinical data insufficient for approval; or

● interruptions or delays in the operations of the FDA and foreign regulatory authorities as a result of the COVID-19 pandemic

may negatively impact review, inspection, and approval timelines.

Even if we succeed in obtaining regulatory approval, the FDA may require post-marketing studies, including additional clinical trials
such as those necessary to assess drug interactions or activity of a product in specific populations which also may be costly. For example, as
part of the accelerated approval of UKONIQ for relapsed or refractory MZL and FL, continued approval for those indications is contingent
upon verification and description of clinical benefit in a confirmatory trial. The outcomes of post-marketing studies may also impact product
labeling and therefore there can be no guarantee that the product attributes contained in the initial prescribing information will be maintained
as future studies produce data. This includes, without limitation, additional results from studies evaluating drug-drug interactions and patients
with certain comorbidities (e.g., hepatic or renal impairment or cardiac risks) among others that may restrict the use of an approved product in
select populations or introduce dose modifications or contraindicated concomitant medications that have the potential to impact the utility of
a product or its perceived product profile among prescribers. Post-marketing studies may also lead to the introduction of new warnings in the
product prescribing information. For example, post-marketing studies may lead to the addition of a

47

 
Table of Contents

boxed warning for UKONIQ. The inclusion of a boxed warning or other required warning language or the addition of limitations to the use of
the product within the indicated population could significantly impact our ability to successfully market our product candidates. Finally, the
FDA may require adoption of a REMS program requiring prescriber training or a post-marketing registry or may restrict the marketing and
dissemination of our products. Any requirements to conduct post-approval studies or fulfill special post-approval requirements could impact
our ability to commercialize our product candidates and increase our costs.

A Breakthrough Therapy or Fast Track designation by the FDA may not actually lead to a faster development or regulatory review or
approval process.

We may seek Breakthrough Therapy or Fast Track designation for some of our drug candidates. For example, in January 2019, the
FDA granted Breakthrough Therapy designation to UKONIQ for the treatment of adult patients with MZL who have received at least one
prior anti-CD20 regimen, and in October 2020, the FDA granted Fast Track designation to the investigation of ublituximab in combination
with UKONIQ for the treatment of adult patients with CLL. If a drug is intended for the treatment of a serious or life-threatening condition,
and  the  drug  demonstrates  the  potential  to  address  an  unmet  medical  need  for  this  condition,  the  Sponsor  may  apply  for  Fast  Track
designation  or  Breakthrough  Therapy  designation,  the  latter  of  which  has  more  significant  requirements.  The  FDA  has  broad  discretion
whether or not to grant these designations, so even if we believe a particular drug candidate is eligible for such a designation, we cannot be
sure that the FDA would decide to grant it. Even if we receive Breakthrough Therapy or Fast Track designation for a drug candidate, we may
not experience a faster development process, review or approval compared to conventional FDA procedures. A drug that receives Fast Track
designation is eligible for more frequent interactions with the FDA, priority review if relevant criteria are met, and rolling submission of the
BLA or NDA. Even if rolling review is allowed, there is no guarantee that the FDA will have commenced or completed review of the BLA or
NDA modules submitted earlier in the rolling review process. Neither Breakthrough Therapy nor Fast Track designation guarantees Priority
Review of an NDA or BLA application. Despite receiving Fast Track designation for U2 for the treatment of adult patients with CLL, the
FDA  granted  the  BLA  a  standard  review  timeline.  The  FDA  may  also  withdraw  a  Breakthrough  Therapy  or  Fast  Track  designation  if  it
believes that the designation is no longer supported by data from our clinical development program.

We have received orphan drug designation for some of our drug candidates for specified indications, and we may seek additional orphan
drug designations for other indications and some of our other drug candidates. However, we may be unsuccessful in obtaining or may be
unable to maintain the benefits associated with orphan drug designation, including the potential for market exclusivity.

Ublituximab as monotherapy received orphan drug designation from the FDA for the treatment of MZL (nodal and extranodal) in
September 2013, for the treatment of CLL in August 2010, and received orphan drug designation by the EMA for the treatment of CLL in
November 2009. We also obtained orphan drug designation for umbralisib as monotherapy for the treatment of CLL in August 2016, all three
types of MZL (nodal, extranodal and splenic) in April 2019, and FL in March 2020. In January 2017, we announced that the FDA granted
orphan drug designation covering the combination of ublituximab and umbralisib for the treatment of patients with CLL and DLBCL. As part
of our business strategy, we may seek orphan drug designation for our other drug candidates; however, we may be unsuccessful. Regulatory
authorities  in  some  jurisdictions,  including  the  United  States,  the  European  Union,  and  the  United  Kingdom,  may  designate  drugs  for
relatively small patient populations as orphan drugs. Under the U.S. Orphan Drug Act, the FDA may designate a drug as an orphan drug if it
is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals
annually in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that
the cost of developing the drug will be recovered from sales in the United States. In the United States, orphan drug designation entitles a
party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers. Orphan
drug designations are required to be maintained through annual reporting and are subject to re-evaluation. Based on the evolving data and
development  plans  for  our  product  candidates  and  changing  incidence  and  prevalence  rates  for  our  intended  indications,  there  can  be  no
guarantee that we will be able to successfully maintain our orphan drug designations for any of our products.

48

 
 
 
 
Table of Contents

Generally,  if  a  product  with  an  orphan  drug  designation  subsequently  receives  the  first  marketing  approval  for  the  indication  for
which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes FDA or EMA from approving
another marketing application for the same drug or biologic for that time period. Even if we obtain orphan drug exclusivity for a drug, that
exclusivity may not effectively protect the designated drug from competition because different drugs can be approved for the same condition.
Even after an orphan drug is approved, the FDA can subsequently approve another product that meets the definition of a “same drug” under
21 C.F.R. 316.3 for the same condition if the FDA concludes that the later product is clinically superior in that it is shown to be safer, more
effective or makes a major contribution to patient care. In addition, a designated orphan drug may not receive orphan drug exclusivity if it is
approved  for  a  use  that  is  broader  than  the  indication  for  which  it  received  orphan  drug  designation.  Moreover,  orphan  drug  exclusive
marketing rights in the United States may be lost if the FDA exercises its authority to revoke orphan drug designation, which it may do on a
variety of grounds, including that the request contained an untrue statement of material fact or omitted material information, or that the drug
in  fact  was  not  eligible  for  orphan  drug  designation.  Orphan  drug  designation  neither  shortens  the  development  time  or  regulatory  review
time of a drug nor gives the drug any advantage in the regulatory review or approval process. While we intend to seek additional orphan drug
designation for our other drug candidates, we may never receive such designations. Even if we receive orphan drug designation for any of our
drug candidates, there is no guarantee that we will enjoy the benefits of those designations or obtain orphan drug exclusivity. In addition, the
U.S. Orphan Drug Act may be subject to amendments that could reduce the period of marketing exclusivity or change the qualifications for
orphan  drug  designation,  which  could  adversely  impact  our  products  or  product  candidates  that  have  or  may  be  eligible  for  orphan  drug
designation.

We are conducting clinical trials, and anticipate additional clinical trials, for product candidates at sites outside the United States, and the
FDA may not accept data from trials conducted in such locations or clinical trial activities in such locations may be impacted by political
conditions, including international conflict.

Many of our Phase 3 and registration-directed clinical trials across our MS and oncology programs, including UNITY-CLL, UNITY-
NHL and ULTIMATE I and II and related extension studies, utilize international clinical research sites. We work with what we believe are
reputable  CROs  and  clinical  research  sites  in  conducting  our  studies  internationally.  Nevertheless,  there  can  be  heightened  challenges  to
monitoring  and  oversight  of  global  clinical  trials  and  sponsors  are  subject  to  the  risk  that  fraud,  misconduct,  incompetence,  unexpected
patient  variability  and  other  issues  affecting  the  reliability,  quality,  and  outcome  of  studies.  The  geographic  variability  of  the  COVID-19
pandemic  also  introduces  increased  risk  in  the  conduct  of  clinical  research  in  certain  countries  and  territories  where  vaccination  rates  and
available standard of care anti-viral therapy varies significantly. Such problems, if they were to occur, could negatively impact trial results,
and  depending  on  the  circumstances  and  scope  of  concerns  could  potentially  even  prevent  a  trial  from  being  useful  or  acceptable  for
regulatory  approval.  If  such  events  were  to  occur  with  respect  to  any  of  our  trials  (and  in  particular  with  respect  to  registration-directed
studies), they would have a substantial negative impact on our business. 

  In  addition,  our  clinical  studies  with  sites  outside  the  United  States  may  be  adversely  impacted  by  international  conflict.  For  example,
tensions  between  Ukraine  and  Russia  have  escalated  in  recent  months,  culminating  in  Russia's  recent  invasion  of  Ukraine.  In  one  or  both
countries, as well as neighboring countries that may be impacted by this conflict (e.g. Poland, Slovakia, Belarus, Georgia), we have clinical
trial sites for our RMS and/or oncology programs. The political and physical conditions in these countries may disrupt our ability to supply
investigational drug product to impacted sites, impact patients’ ability to partake in the clinical trial, or result in suspension of clinical trial
activities  at  impacted  sites.  While  we  do  not  believe  this  conflict  will  have  a  material  impact  on  our  current  regulatory  submissions  for
approval  of  ublituximab  in  RMS  or  U2  in  CLL  or  our  overall  business,  given  the  rapidly  evolving  situation  and  the  potential  to  expand
beyond Ukraine and Russia, the full impact of the conflict remains uncertain.

An approval of one of our product candidates in the United States would not assure approval of that candidate in foreign jurisdictions.

We intend to seek product approvals in certain countries outside of the United States. The approval procedures for pharmaceuticals
vary among countries and obtaining approval in one jurisdiction does not guarantee approval in another jurisdiction. For example, even if the
FDA grants approval of a product candidate, comparable regulatory authorities in foreign jurisdictions may not approve the same product
candidate  or  may  require  additional  evidence  for  approval.  The  time  required  to  obtain  approval  in  other  countries  might  differ  from  that
required to obtain FDA approval. In many countries outside the United States, the product must be approved for reimbursement before it can
be marketed. As a general matter, however, the foreign regulatory approval process involves a lengthy and challenging process with risks
similar  or  identical  to  the  risks  associated  with  the  FDA  approval  discussed  above.  Therefore,  we  cannot  guarantee  that  we,  or  future
collaborators, will obtain approvals of our product candidates in any foreign jurisdiction on a timely basis, if at all. Failure to receive approval
in  certain  foreign  markets  could  significantly  impact  the  full  market  potential  of  our  product  candidates  and  may  negatively  impact  the
regulatory process in other countries. Furthermore, if we obtain regulatory approval for a product candidate in a foreign jurisdiction, we will

49

 
Table of Contents

be subject to the burden of complying with complex regulatory, legal, and other requirements that could be costly and could subject us to
additional risks and uncertainties.

We have product candidates still under development and are also preparing for commercial manufacturing activities, and as such clinical
and commercial manufacturing site additions, scale-up and process improvements implemented in the production of those product
candidates may affect their ultimate activity or function.

Many of our product candidates are currently manufactured in relatively small batches for use in pre-clinical and clinical studies.
Process improvements implemented to date have changed, and process improvements in the future may change, the activity and/or analytical
profile  of  the  product  candidates,  which  may  affect  the  safety  and  efficacy  of  the  products.  For  instance,  the  manufacturing  process  for
ublituximab  has  undergone  several  process  improvements  during  the  clinical  trial  process  which  have  resulted  in  analytical  differences
between  the  materials.  Such  process  improvements  continued  during  the  conduct  of  the  Phase  3  study  and  materials  from  more  than  one
manufacturing process were utilized in the Phase 3 UNITY-CLL trial and the Phase 3 ULTIMATE I and II trials. While analytical differences
exist between those materials, we do not believe the differences will alter the safety or efficacy profile of ublituximab. However, it is possible
that  additional  and/or  different  adverse  events  may  appear  among  patients  exposed  to  drug  product  manufactured  under  one  process
compared to the other, or that adverse events may arise with greater frequency, intensity and duration among patients exposed to drug product
manufactured under one process compared to the other. Additionally, the efficacy of ublituximab may also be negatively impacted by such
process changes. Given the uncertainty of the impact on product specifications, quality and performance, process improvements made during
Phase 3 development carry a higher level of risk than those made prior to Phase 3 development. If there are significant differences in product
attributes  between  the  two  materials,  we  may  need  to  conduct  additional  analyses  of  the  Phase  3  study(ies)  to  confirm  that  there  is  no
difference in safety or efficacy between the product made by each process in order to allow us to utilize data from all enrolled patients, as
well as be able to integrate clinical safety and/or efficacy results across studies to support any potential marketing application. There can be
no assurance given that such analyses will be successful in demonstrating that there are no clinical differences between these drug products,
which could substantially impact the approvability of the combination of UKONIQ and ublituximab based on the results of the UNITY-CLL
study. In such circumstances, that would have a material adverse effect on the Company.

Further, no assurance can be given that the material manufactured from any future optimized processes, if any, for ublituximab or
any of our product candidates will perform comparably to the product candidates as manufactured to date which could result in an unexpected
safety or efficacy outcome as compared to the data published or presented to date. Similarly, following each round of process improvements,
if any, for any of our drug candidates, future clinical trial results conducted with the new material will be subject to uncertainty related to the
effects, if any, of those additional process improvements that were made.

In  addition,  with  the  FDA  approval  of  UKONIQ  and  as  we  move  closer  to  commercialization  of  ublituximab,  we  are  scaling-up
production to ensure adequate commercial supply. This is an expensive process and there can be no assurance given that such scale-up will be
successful in providing pharmaceutical product that is of sufficient quantity, or of a quality that is consistent with our previously established
specifications,  or  that  meets  the  requirements  set  by  regulatory  agencies  under  which  we  may  seek  approval  of  our  product  candidates.  If
scale-up were not to succeed, our ability to supply our anticipated market at a reasonable cost of goods would be negatively impacted. In such
an event, that would have a material adverse effect on the Company. Scale up could also require additional process improvement that might
be required to accommodate new and larger equipment utilized in the scaled-up process. If that were to occur and we could not demonstrate
to the FDA that the materials were analytically substantially similar, we might be required to run additional clinical testing to demonstrate
that  they  are  substantially  similar.  That  would  entail  a  significant  delay  and  significant  increase  in  total  cost,  all  of  which  would  have  a
material adverse effect on the Company.

Risks Related to Governmental Regulation of Pharmaceutical Industry and Legal Compliance Matters

We are subject to new legislation, regulatory proposals and third-party payor initiatives that may increase our costs of compliance and
adversely affect our ability to market our products, obtain collaborators and raise capital.

In both the United States and certain foreign countries, there have been a number of legislative and regulatory changes or proposed
changes to the healthcare system, many of which have focused on prescription drug pricing and lowering overall healthcare costs, that could
impact our ability to sell our products profitably and support future innovation. We expect prescription drug pricing and other healthcare costs
to continue to be subject to intense political and social pressures on a global basis.

In  the  United  States,  the  President,  federal  and  state  legislatures,  health  agencies  and  third-party  payors  continue  to  focus  on
containing the cost of healthcare and addressing public concern over access and affordability of prescription drugs. The Patient Protection
and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the ACA) was enacted in
2010 and made significant changes to the U.S. healthcare system. ACA changes included expanding healthcare coverage through Medicaid
expansion  and  implementation  of  the  individual  health  insurance  mandate;  changing  coverage  and  reimbursement  of  drug  products  under
government  healthcare  programs;  imposing  an  annual  fee  on  manufacturers  of  branded  drugs;  and  expanding  government  enforcement
authority. Although the ACA has been the subject of a number of legislative and litigation challenges since it passed, it is expected that the
Biden Administration will seek to strengthen and expand the ACA. We cannot predict what effect further changes to the ACA would have on
our business.

Beyond the ACA, there has been increasing legislative, regulatory and enforcement interest with respect to prescription drug pricing
practices. With the election of President Biden and changes in make-up of the Senate following the 2020 election, we face uncertainties with
respect  to  executive  and  legislative  actions  relating  to  drug  pricing.  Proposals  that  may  garner  bipartisan  legislative  support  or  become
legislation through reconciliation include adding a cap on out-of-pocket spending under Medicare Part D, authorizing Medicare to negotiate
certain drugs covered by Medicare Parts D and B directly with manufacturers, and imposing limits on increases in drug prices. In addition,
President Biden may take executive action to introduce new drug pricing models and other drug pricing initiatives. The Biden Administration
also may propose substantial changes to the U.S. healthcare system, including expanding government-funded health insurance options. We
are uncertain of the impact or outcome of potential Executive Orders, rescission of rules and policy statements, or new legislation, especially
any relative impact on the healthcare regulatory and policy landscape, or the impact they may have on our business. We expect drug pricing
will continue to be a focus of the Biden Administration. At the state level, legislatures have increasingly passed legislation and implemented
regulations designed to control pharmaceutical 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.

There  have  been  several  recent  U.S.  Congressional  inquiries  and  proposed  and  enacted  legislation  designed  to  bring  more
transparency to drug pricing, reduce the cost of prescription drugs under Medicare, limit price increases, evaluate the relationship between
pricing and manufacturer patient programs, and reform government health care program reimbursement methodologies for prescription drugs.
For example, the Bipartisan Budget Act of 2018 (the BBA) increased manufacturer point-of-sale discounts off negotiated prices of applicable
brand drugs in the Medicare Part D coverage gap from 50% to 70% effective as of January 1, 2019, ultimately increasing the liability for
brand  drug  manufacturers.  We  expect  that  health  care  reform  measures  that  may  be  adopted  in  the  future,  may  result  in  more  rigorous
coverage criteria, increase manufactured financial liability, and additional downward pressure on the price that we may receive for any of our
product candidates, if approved. Any reduction in reimbursement from Medicare or other government health care programs may result in a
similar reduction in payments from private payors.

There continue to be efforts to lower drug prices through increased competition, with policy proposals seeking to facilitate generic
and biosimilar approval and marketing authorization. For example, in 2018, the FDA announced the Biosimilar Action Plan and sought input
on how the agency can best facilitate greater availability of biosimilar products, including input on whether changes to an approved biologic
(e.g., a new indication) would be protected by the remainder of the statutory 12-year exclusivity period (commonly referred to as “umbrella
exclusivity”).  In  the  event  there  is  a  modification  to  the  biologic  exclusivity  period  or  other  steps  taken  to  facilitate  biosimilar  or  generic
approvals, we could experience biosimilar/generic competition of any products for which we receive FDA approval at an earlier time than
currently anticipated.

At  the  state  level,  individual  states  are  experiencing  significant  economic  pressure  within  their  state  Medicaid  programs  and
responding  to  public  concern  over  the  cost  of  healthcare.  The  economic  impact  of  the  COVID-19  pandemic  has  further  exacerbated  state
budgetary pressures. States, including California, Florida, Nevada and Maine, among others, have responded to these pressures with a range
of  legislative  enactments  and  policy  proposals  designed  to  control  prescription  drug  prices  by,  for  example,  allowing  importation  of
pharmaceutical  products  from  jurisdictions  outside  the  U.S.,  imposing  price  controls  on  state  drug  purchases,  consolidating  state  drug
purchasing to a single purchaser, and imposing transparency measures around prescription drug prices and marketing costs. These measures,
which vary by state, could reduce the ultimate demand for our products, if approved, or put pressure on our product pricing.

51

Table of Contents

In addition, other legislative changes have been adopted that could have an adverse effect upon, and could prevent, our products’ or
product candidates’ commercial success. More broadly, the Budget Control Act of 2011, as amended, or the Budget Control Act, includes
provisions intended to reduce the federal deficit, including reductions in Medicare payments to providers through 2030 (except May 1, 2020
to  December  31,  2020).  Any  significant  spending  reductions  affecting  Medicare,  Medicaid  or  other  publicly  funded  or  subsidized  health
programs,  or  any  significant  taxes  or  fees  imposed  as  part  of  any  broader  deficit  reduction  effort  or  legislative  replacement  to  the  Budget
Control Act, or otherwise, could have an adverse impact on our anticipated product revenues.

Furthermore,  legislative  and  regulatory  proposals  have  been  made  to  expand  post-approval  requirements  and  restrict  sales  and
promotional activities for drugs. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations,
guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any,
may be. In addition, increased scrutiny by Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as
well as subject us to more stringent product labeling and post-marketing testing and other requirements.

In  many  international  markets,  including  the  European  Union,  the  government  regulates  prescription  drug  prices,  patient  access,
and/or reimbursement levels to control the biopharmaceutical budget of their government-sponsored healthcare system. The European Union
and some individual countries have announced or implemented measures and may in the future implement new or additional measures, to
reduce  biopharmaceutical  costs  to  contain  the  overall  level  of  healthcare  expenditures.  These  measures  vary  by  country  and  may  include,
among other things, non-coverage decisions, patient access restrictions, international price referencing, mandatory discounts or rebates, and
cross-border sales of prescription drugs. These measures may adversely affect our ability to generate revenues or commercialize our product
candidates in certain international markets.

There likely will continue to be pressure on prescription drug prices globally and legislative and regulatory proposals, including at
the federal and state levels in the U.S., directed at broadening the availability of health care and containing or lowering the cost of health care
products and services. We cannot predict the initiatives that may be adopted in the future. The continuing efforts of the government, health
insurance  companies,  managed  care  organizations  and  other  payors  of  health  care  services  to  contain  or  reduce  costs  of  health  care  may
adversely affect, among other things:

● our ability to generate revenues and achieve or maintain profitability;
● the demand for any products for which we may obtain regulatory approval;
● our ability to set a price that we believe is fair for our products;
● the level of taxes that we are required to pay; and
● the availability of capital.

In addition, governments may impose price controls, which may adversely affect our future profitability.

Our  relationships  with  customers  and  third-party  payors  will  be  subject  to  applicable  fraud  and  abuse  laws,  false  claims  laws,
transparency and disclosure laws, health information and security laws, and other healthcare laws and regulations, which could expose
us to criminal sanctions, civil penalties, exclusion from government healthcare programs, contractual damages, reputational harm and
diminished profits and future earnings.

With  the  FDA  approval  of  UKONIQ  in  February  2021,  we  became  subject  to  additional  extensive  healthcare  statutory  and
regulatory requirements and oversight by the federal government and the states and foreign governments in which we conduct our business.
Healthcare providers and third-party payors play a primary role in the recommendation and prescription of any drug candidates for which we
obtain marketing approval. Our past, current and future relationships, arrangements and interactions with these professionals and entities, as
well as with patients and patient advocacy organizations will expose us to broadly applicable fraud and abuse and other healthcare laws and
regulations that may constrain the business or financial arrangements and relationships through which we market, sell and distribute our drug
candidates for which we obtain marketing approval. Restrictions under applicable federal and state healthcare laws and regulations include
the following:

52

 
 
Table of Contents

● the  federal  Anti-Kickback  Statute  prohibits,  among  other  things,  persons  from  knowingly  and  willfully  soliciting,  offering,
receiving  or  providing  remuneration,  directly  or  indirectly,  in  cash  or  in  kind,  to  induce  or  reward  either  the  referral  of  an
individual  for,  or  the  purchase,  order  or  recommendation  of,  any  good  or  service,  for  which  payment  may  be  made  under
federal  and  state  healthcare  programs  such  as  Medicare  and  Medicaid.  A  person  or  entity  does  not  need  to  have  actual
knowledge of the statute or specific intent to violate it in order to have committed a violation;

● the  federal  False  Claims  Act  imposes  civil  penalties,  including  through  civil  whistleblower  or  qui  tam  actions,  against
individuals  or  entities  for,  among  other  things,  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government,
claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay
money to the federal government. In addition, the government may assert that a claim including items and services resulting
from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims
Act;

● the  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996  (or  HIPAA)  imposes  criminal  and  civil  liability  for
executing a scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up
a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits,
items or services; similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the
statute or specific intent to violate it in order to have committed a violation;

● the  so-called  federal  “Sunshine  Act”  under  the  Affordable  Care  Act  requires  manufacturers  of  drugs,  devices,  biologics  and
medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program to monitor and
report information related to payments and other transfers of value to and the ownership and investment interests of physicians
and  teaching  hospitals  (and  additional  categories  of  healthcare  providers  beginning  with  reports  submitted  in  2022)  to  the
federal government for redisclosure to the public;

● HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 and its implementing
regulations,  which  also  imposes  obligations  on  certain  covered  entity  healthcare  providers,  health  plans,  and  healthcare
clearinghouses as well as their business associates that perform certain services involving the use or disclosure of individually
identifiable health information, including mandatory contractual terms, with respect to safeguarding the privacy, security and
transmission of individually identifiable health information;

● a  wide  range  of  federal  and  state  consumer  protection  and  unfair  competition  laws,  which  broadly  regulate  marketplace

activities and activities that potentially harm consumers including those related to privacy;

● the Federal Food, Drug, and Cosmetic Act and its implementing regulations, which among other things, strictly regulate drug
product  marketing  and  prohibit  manufacturers  from  promotion  and  marketing  of  products  prior  to  approval  or  for  uses
inconsistent with the FDA-required labeling;

● federal  laws,  including  the  Medicaid  Drug  Rebate  Program,  that  require  pharmaceutical  manufacturers  to  report  certain
calculated product prices to the government or provide certain discounts or rebates to government authorities or private entities,
often as a condition of reimbursement under government healthcare programs;

● the Drug Supply Chain Security Act, or DSCSA, which imposes obligations on entities in the commercial product supply chain,

including manufacturers, to identify and track prescription drugs as they are distributed in the U.S.; and

● state law equivalents of some of the above federal laws, such as anti-kickback and false claims laws that may apply to items or
services  reimbursed  by  any  third-party  payor,  including  commercial  insurers,  state  transparency  laws,  state  laws  limiting
interactions  between  pharmaceutical  manufacturers  and  members  of  the  healthcare  industry,  and  state  laws  governing  the
privacy and security of health information in certain circumstances, many of which differ from each other in significant ways
and often are not preempted by federal laws, thus complicating compliance efforts.

In the U.S., to help patients who have no or inadequate insurance coverage of UKONIQ, we have a patient support program that we
administer in conjunction with a patient support program vendor and other third parties. There has been heightened governmental scrutiny
over the scope of patient support programs and the manner in which drug manufacturers and their vendors operate such programs. We cannot
ensure that our compliance controls, policies, and procedures will be sufficient to protect against acts of our employees, business partners or
vendors that may violate the laws, regulations, or evolving government guidance on patient support programs. A government investigation,
regardless of its outcome, could impact our business practices, harm our reputation, divert attention of management, increase our expenses
and  reduce  availability  of  assistance  to  patients.  If  we  or  our  vendors  are  deemed  to  fail  to  comply  with  relevant  laws,  regulations  or
government  guidance  in  the  operation  of  these  programs,  we  could  be  subject  to  damages,  fines,  penalties  or  other  criminal,  civil  or
administrative sanctions or enforcement actions.

Ensuring  that  our  future  business  arrangements  with  third  parties  comply  with  applicable  healthcare  laws  and  regulations  will
involve substantial costs. It is possible that governmental authorities will conclude that our business practices do not comply with current or
future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. The compliance and
enforcement landscape, and related risk, is informed by government enforcement precedent and settlement history, Advisory Opinions, and
Special Fraud Alerts. Our approach to compliance may evolve over time in light of these types of developments. Additionally, the potential
safe  harbors  available  under  the  AKS  are  subject  to  change  through  legislative  and  regulatory  action,  and  we  may  decide  to  adjust  our
business practices or be subject to heightened scrutiny as a result. If our operations, including anticipated activities to be conducted by our
sales team, were to be found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be
subject  to  significant  civil,  criminal  and  administrative  penalties,  damages,  fines,  exclusion  from  government-funded  healthcare  programs,
such as Medicare and Medicaid, qui tam actions brought by individual whistleblowers in the name of the government, and the curtailment or
restructuring of our operations.

If we violate applicable data privacy and security laws, we may be subject to penalties, including civil and criminal penalties, damages,
fines and the curtailment or restructuring of our operations.

We  may  be  subject  to  privacy  and  security  laws  in  the  various  jurisdictions  in  which  we  operate,  obtain  or  store  personally
identifiable information. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an
increasing focus on privacy and data protection issues with the potential to affect our business.

Within the United States, various federal and state laws regulate the privacy and security of personal information and so may affect
our  business  operations.  For  example,  at  the  federal  level,  our  operations  may  be  affected  by  the  data  privacy  and  security  provisions  of
HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act  and  its  implementing  regulations.
Although we are not currently directly subject to HIPAA, HIPAA affects the ability of healthcare providers and other entities with which we
may interact, including clinical trial sites, to disclose patient health information to us. Under Section 5(a) of the Federal Trade Commission
Act,  or  the  FTCA,  the  FTC  expects  a  company’s  data  security  measures  to  be  reasonable  and  appropriate  in  light  of  the  sensitivity  and
volume  of  consumer  information  it  holds,  the  size  and  complexity  of  its  business,  and  the  cost  of  available  tools  to  improve  security  and
reduce  vulnerabilities.  Medical  data  is  considered  sensitive  data  that  merits  stronger  safeguards.  States  may  also  impose  requirements,  for
example the California Consumer Privacy Act, or the CCPA, went into effect in January 2020 creating data privacy obligations for covered
companies and providing privacy rights to California residents, including the right to opt out of certain disclosures of their information.

Numerous  other  jurisdictions  regulate  the  privacy  and  security  of  personally  identifiable  data.  For  example,  the  processing  of
personal data in the European Economic Area, or the EEA, is subject to the General Data Protection Regulation, or the GDPR, which took
effect in May 2018. The GDPR increases obligations with respect to clinical trials conducted in the EEA, such as in relation to the provision
of fair processing notices, exercising data subject rights and reporting certain data breaches to regulators and affected individuals, as well as
how we document our relationships with third parties that process GDPR-covered personal data on our behalf. The GDPR also increases the
scrutiny applied to transfers of personal data from the EEA (including from clinical trial sites in the EEA) to countries that are considered by
the European Commission to lack an adequate level of data protection, such as the United States. In July 2020, the Court of Justice of the
European Union invalidated the EU-U.S. Privacy Shield framework, one of the mechanisms used to legitimize the transfer of personal data
from the EEA to the U.S., which decision may lead to increased scrutiny on data transfers from the EEA to the U.S. generally and increase
our costs of compliance with data privacy legislation.

If our operations are found to be in violation of any data privacy and security laws, rules or 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, which 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, rules or regulations, we cannot be certain that our program will address all areas of
potential  exposure  and  the  risks  in  this  area  cannot  be  entirely  eliminated,  particularly  because  the  requirements  and  government
interpretations  of  the  requirements  in  this  space  are  constantly  evolving.  Any  action  against  us  for  violation  of  these  laws,  rules  or
regulations,  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, as well as damage our business or reputation. Moreover, achieving and sustaining compliance
with applicable federal and state privacy, security, fraud and reporting laws may prove costly.

If  we  fail  to  adequately  understand  and  comply  with  the  local  laws  and  customs  as  we  expand  into  new  international  markets,  these
operations may incur losses or otherwise adversely affect our business and results of operations.

We expect to operate a portion of our business in certain countries through subsidiaries or through supply, marketing, and distributor
arrangements. In those countries where we have limited experience in operating subsidiaries and in reviewing equity investees, we will be
subject to additional risks related to complying with a wide variety of national and local laws, including restrictions on the import and export
of certain intermediates, drugs, technologies and multiple and possibly overlapping tax laws. In addition, we may face competition in certain
countries from companies that may have more experience with operations in such countries or with international operations generally. We
may also face difficulties integrating new facilities in different countries into our existing operations, as well as integrating employees hired
in  different  countries  into  our  existing  corporate  culture.  If  we  do  not  effectively  manage  our  operations  in  these  subsidiaries  and  review
equity  investees  effectively,  or  if  we  fail  to  manage  our  alliances,  we  may  lose  money  in  these  countries,  and  it  may  adversely  affect  our
business and results of our operations. In all interactions with foreign regulatory authorities and other government agencies, we are exposed
to liability risks under the Foreign Corrupt Practices Act or similar anti-bribery laws.

Any  product  for  which  we  obtain  marketing  approval  could  be  subject  to  restrictions  or  withdrawal  from  the  market  and  we  may  be
subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with products.

Any regulatory approvals that we receive for our drug candidates may be subject to limitations on the indicated uses for which the
drug may be marketed or to conditions of approval that may require potentially costly post-marketing clinical trials or surveillance to monitor
safety and efficacy of the drug candidate. In addition, any product for which we obtain marketing approval, along with the manufacturing
processes  and  facilities,  post-approval  clinical  data,  labeling,  advertising  and  promotional  activities  for  such  product,  will  be  subject  to
continual requirements of, and review by, the FDA and comparable regulatory authorities. These requirements include submissions of safety
and  other  post-marketing  information  and  reports,  registration  requirements,  current  Good  Manufacturing  Practice  (cGMP)  requirements
relating  to  quality  control,  quality  assurance  and  corresponding  maintenance  of  records  and  documents,  and  requirements  regarding
promotional interactions with healthcare professionals.

Failure  to  comply  with  these  regulatory  requirements  or  later  discovery  of  previously  unknown  problems  with  products,

manufacturers, or manufacturing processes, may result in actions such as:

● restrictions on product manufacturing, distribution or use;
● restrictions on the labeling or marketing of a product;
● requirements to conduct post-marketing studies or clinical trials;
● warning letters;
● withdrawal of the products from the market;
● refusal to approve pending applications or supplements to approved applications that we or our subsidiaries submit;
● recalls;
● suspension or termination of ongoing clinical trials;
● fines, restitutions, or disgorgement of profits or revenues;
● refusal to permit the import or export of products;
● product seizure or detentions;
● injunctions or the imposition of civil or criminal penalties; and
● adverse publicity.

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and
could  generate  negative  publicity.  In  addition,  the  FDA’s  regulations,  policies  or  guidance  may  change  and  new  or  additional  statutes  or
government  regulations  may  be  enacted  that  could  prevent  or  delay  regulatory  approval  of  our  product  candidates  or  further  restrict  or
regulate  post-approval  activities.  We  also  cannot  predict  the  likelihood,  nature,  or  extent  of  adverse  government  regulation  that  may  arise
from pending or future legislation or administrative action, either in the United States or abroad.

If we, or our respective suppliers, third-party contractors, clinical investigators or collaborators are slow to adapt, or are unable to
adapt,  to  changes  in  existing  regulatory  requirements  or  adoption  of  new  regulatory  requirements  or  policies,  we,  our  subsidiaries,  or  our
respective collaborators may be subject to the actions listed above, including losing marketing approval for products, resulting in decreased
revenue from milestones, product sales or royalties.

55

Our third-party manufacturers may use hazardous materials in the production of UKONIQ and our product candidates and if so, they
must comply with environmental laws and regulations, which can be expensive and restrict how we or they do business.

Manufacturing activities for the production of UKONIQ and our product candidates involve the controlled storage, use, and disposal
of hazardous materials, including the components of our product candidates, and other hazardous compounds. Our third-party manufacturers
and we are subject to federal, state, and local laws and regulations governing the use, manufacture, storage, handling, release, disposal of, and
exposure  to,  these  hazardous  materials.  Violation  of  these  laws  and  regulations  could  lead  to  substantial  fines  and  penalties.  Although  we
believe that our safety procedures, and those of our third-party manufacturers, for handling and disposing of these materials comply with the
standards prescribed by these laws and regulations, we cannot eliminate the risk of accidental contamination or injury from these materials. In
the event of an accident, state or federal authorities may curtail our use of these materials and interrupt our business operations. In addition,
we could become subject to potentially material liabilities relating to the investigation and cleanup of any contamination, whether currently
unknown or caused by future releases.

Risks Related to Our Dependence on Third Parties

We rely on third parties to generate clinical, preclinical and other data necessary to support the regulatory applications needed to conduct
clinical trials and submit for marketing approval. We rely on third parties to help conduct our planned clinical trials. If these third parties
do not perform their services as required, we may not be able to obtain regulatory approval for or commercialize our product candidates
when expected or at all.

In order to submit an Investigational New Drug application (IND), BLA, or NDA to the FDA and maintain these applications, it is
necessary  to  submit  all  information  on  the  clinical,  non-clinical,  chemistry,  manufacturing,  controls  and  quality  aspects  of  the  product
candidate.  Clinical  trial  applications  and  marketing  authorization  applications  for  foreign  regulatory  bodies  have  substantially  similar
requirements. We rely on our third-party contractors and our licensing partners to provide portions of this data. If we are unable to obtain this
data, or the data is not sufficient to meet the regulatory requirements, we may experience significant delays in our development programs.

Additionally, we use CROs to assist in the conduct of our current clinical trials and expect to use such services for future clinical
trials  and  we  rely  upon  medical  institutions,  clinical  investigators  and  contract  laboratories  to  conduct  our  trials  in  accordance  with  our
clinical protocols and appropriate regulations. Our current and future CROs, investigators and other third parties play a significant role in the
conduct  of  our  trials  and  the  subsequent  collection  and  analysis  of  data  from  the  clinical  trials.  There  is  no  guarantee  that  any  CROs,
investigators and other third parties will devote adequate time and resources to our clinical trials or perform as contractually required. If any
third  parties  upon  whom  we  rely  for  administration  and  conduct  of  our  clinical  trials  fail  to  meet  expected  deadlines,  fail  to  adhere  to  its
clinical protocols or otherwise perform in a substandard manner, our clinical trials may be extended, delayed or terminated, and we may not
be able to commercialize our product candidates. In addition to the third parties identified above, we are also heavily reliant on the conduct of
our patients enrolled to our studies by our third-party investigators. We rely on our clinical trial sites and investigators to properly identify
and  screen  eligible  candidates  for  our  clinical  trials,  and  for  them  to  ensure  participants  adhere  to  our  clinical  protocol  requirements.  The
majority of our clinical trial conduct occurs in the outpatient setting, where patients are expected to continue to adhere to our study protocol
specified requirements. The ability of our enrolled patients to properly identify, document, and report adverse events; take protocol specified
study  drugs  at  the  correct  quantity,  time,  and  setting,  as  applicable;  avoid  contraindicated  medications;  and  comply  with  other  protocol
specified  procedures  such  as  returning  to  the  trial  site  for  scheduled  laboratory  and  disease  assessments,  is  wholly  out  of  our  control.
Deviations  from  protocol  procedures,  such  as  those  identified  previously,  could  materially  affect  the  quality  of  our  clinical  trial  data,  and
therefore ultimately affect our ability to develop and commercialize our drug candidates. If any of our clinical trial sites terminates for any
reason, we may experience the loss of follow-up information on patients enrolled in our ongoing clinical trials unless we are able to transfer
the care of those patients to another qualified clinical trial site. If any of our clinical trial sites is required by the FDA or IRB to close down
due to data management or patient management or any other issues, we may lose patients.

Whether conducted through a CRO or through our internal staff, we are solely responsible for ensuring that each of our clinical trials
is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards, and our reliance on CROs
will not relieve us of our regulatory responsibilities. For any violations of laws and regulations during the conduct of our clinical trials, we
could be subject to warning letters or other enforcement actions that may include civil penalties up to and including criminal prosecution. We
and our CROs are required to comply with regulations, including GCP guidelines for conducting, monitoring, recording and reporting the
results of clinical trials to ensure that the data and results are scientifically credible and accurate, and that the trial patients are adequately
informed of the potential risks of participating in clinical trials and their rights are protected. These regulations are enforced by the FDA, the
Competent Authorities of the Member States of the European Economic Area and comparable foreign regulatory authorities

56

for any drug candidates in clinical development. The FDA enforces GCP regulations through periodic inspections of clinical trial sponsors,
clinical  investigators,  CROs,  institutional  review  boards,  and  non-clinical  laboratories.  If  we,  our  CROs,  our  investigators  or  other  third
parties  fail  to  comply  with  applicable  GCPs,  the  clinical  data  generated  in  our  clinical  trials  may  be  deemed  unreliable  and  the  FDA  or
comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications.
We cannot assure you that, upon inspection, the FDA will determine that our current or future clinical trials comply with GCPs. In addition,
our  clinical  trials  must  be  conducted  with  drug  candidates  produced  under  cGMP  regulations.  Our  failure  or  the  failure  of  our  CROs  or
CMOs to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process and could
also subject us to enforcement action. We also are required to register most ongoing clinical trials and post the results of completed clinical
trials  on  government-sponsored  databases,  e.g.,  ClinicalTrials.gov,  within  certain  timeframes.  Failure  to  do  so  can  result  in  fines,  adverse
publicity and civil and criminal sanctions.

CROs play an important role in the conduct of our clinical trials, especially outside of the United States. As a result, many important
aspects of our development programs, including their conduct and timing, will be outside of our direct control. Our reliance on third parties to
conduct current or future clinical trials will also result in less direct control over the management of data developed through clinical trials
than  would  be  the  case  if  we  were  relying  entirely  upon  our  own  staff.  Communicating  with  outside  parties  can  also  be  challenging,
potentially leading to mistakes as well as difficulties in coordinating activities. Outside parties may:

● have staffing difficulties;
● fail to comply with contractual obligations;
● experience regulatory compliance issues;
● undergo changes in priorities or become financially distressed; or
● form relationships with other entities, some of which may be our competitors.

These factors may materially adversely affect the willingness or ability of third parties to conduct our clinical trials and may subject
us to unexpected cost increases that are beyond our control. If the CROs do not perform clinical trials in a satisfactory manner, breach their
obligations to us or fail to comply with regulatory requirements, the development, regulatory approval and commercialization of our drug
candidates may be delayed, we may not be able to obtain regulatory approval and commercialize our drug candidates, or our development
program may be materially and irreversibly harmed. If we are unable to rely on clinical data collected by our CROs, we could be required to
repeat, extend the duration of, or increase the size of any clinical trials we conduct, and this could significantly delay commercialization and
require significantly greater expenditures.

If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative
CROs. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or
if  the  quality  or  accuracy  of  the  clinical  data  they  obtain  is  compromised  due  to  the  failure  to  adhere  to  our  clinical  protocols,  regulatory
requirements or for other reasons, any clinical trials such CROs are associated with may be extended, delayed or terminated, and we may not
be  able  to  obtain  regulatory  approval  for  or  successfully  commercialize  our  product  candidates.  As  a  result,  we  believe  that  our  financial
results and the commercial prospects for our product candidates in the subject indication would be harmed, our costs could increase and our
ability to generate revenue could be delayed.

We  contract  with  third  parties  for  the  manufacture  of  UKONIQ  for  commercial  supply  and  of  our  product  candidates  for  pre-clinical
development  and  clinical  trials,  and  we  expect  to  continue  to  do  so,  including  for  commercial  supply  of  ublituximab.  This  reliance  on
third parties increases the risk that we will not have sufficient quantities of our products or product candidates or such quantities at an
acceptable cost or quality, which could delay, prevent or impair our development or commercialization efforts.

We do not currently own or operate, nor do we have any plans to establish in the future, any manufacturing facilities. We rely, and
expect  to  continue  to  rely,  on  third  parties  for  the  manufacture,  packaging  and  labeling  of  any  products  that  we  commercialize  and  our
product candidates for pre-clinical development and clinical testing. In some circumstances, our licensor has entered into arrangements with
contract manufacturers to supply product for our clinical and commercial demand. Our reliance on third parties increases the risk that we will
not  have  sufficient  quantities  of  our  products  or  product  candidates  or  such  quantities  at  an  acceptable  cost  or  quality,  which  could  delay,
prevent or impair our development or commercialization efforts.

The  facilities  used  by  contract  manufacturers  to  manufacture  our  drug  candidates  typically  undergo  inspections  by  the  FDA  or  a
comparable foreign regulatory to verify compliance with applicable cGMP regulations. Such inspections may be conducted after we submit
our marketing applications to or receive marketing approval from the FDA or a comparable foreign regulatory authority. Although the FDA
and other regulators impose requirements regarding our selection, qualification, oversight, and monitoring of our contract manufacturers and
hold  us  responsible  for  the  ultimate  compliance  of  our  products,  we  do  not  directly  control  the  manufacturing  process  of  our  third-party
contract manufacturers and are subject to risks associated with their ability to comply with cGMPs in connection with the manufacture of our
products and product candidates. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications
and  the  strict  regulatory  requirements  of  the  FDA  or  others  and  the  compliance  concerns  cannot  be  resolved,  remediated,  or  otherwise
addressed  to  the  FDA’s  satisfaction  in  a  timely  manner  during  the  review  of  our  NDAs  or  BLAs,  it  may  negatively  impact  our  ability  to
obtain regulatory approval for our drug candidates or obtain approval within projected timelines. We cannot guarantee the ability of our third-
party  manufacturers  to  maintain  compliance  with  cGMP  regulations,  including  having  adequate  quality  control,  quality  assurance  and
qualified personnel. Further, our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in
sanctions  being  imposed  on  us,  including  clinical  holds,  fines,  injunctions,  civil  penalties,  delays,  suspension  or  withdrawal  of  approvals,
license revocation, seizures or recalls of products or product candidates, operating restrictions and criminal prosecutions, any of which could
significantly and adversely affect our business and supplies of our products or product candidates.

For umbralisib and certain of our product candidates, we do not have long-term supply agreements with contract manufacturers. For
these product candidates, we purchase our required drug supply, including the drug product and drug substance on a purchase order basis. We
may  be  unable  to  establish  or  maintain  agreements  with  third-party  manufacturers  for  these  products  or  product  candidates  or  do  so  on
acceptable  terms.  No  assurance  can  be  given  that  long-term,  scalable  manufacturers  can  be  identified  or  that  they  can  make  clinical  and
commercial supplies of our product candidates that meet the product specifications of previously manufactured batches, or are of a sufficient
quality, or at an appropriate scale and cost to make it commercially feasible. If they are unable to do so, it could have a material adverse
impact on our business.

Even if we are able to establish and maintain long-term agreements with third-party manufacturers as we have with ublituximab,

reliance on third-party manufacturers entails additional risks, including:

● reliance on the third party for regulatory compliance and quality assurance;
● the possible breach of the manufacturing or supply agreement by the third party;
● the possible misappropriation of our proprietary information, including our trade secrets and know-how; and
● the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us.

Moreover,  our  current  long-term  supply  agreement  for  ublituximab  contains  certain  minimum  purchases  in  what  are  commonly
referred  to  as  a  “take  or  pay”  provision,  and  it  is  possible  that  future  supply  agreements  could  contain  such  provisions.  To  the  extent  our
demand does not meet the minimum supply required amounts, we would be forced to pay more than desired. This could create a situation
where  we  are  spending  more  than  required  and  could  impact  our  on-going  operations  and  entail  curtailing  other  important  research  and
development  or  commercialization  efforts,  all  of  which  could  have  a  material  adverse  effect  on  the  Company.  In  negotiating  our  supply
agreement for ublituximab, there is no guarantee that we have foreseen all eventualities or that our third-party manufacturer will be able to
accommodate  unforeseen  changes  in  business  direction  in  a  timely  fashion  or  at  all.  Scheduling  of  manufacturing  at  our  third-party
manufacturer  is  governed  by  contractual  terms  that  require  us  to  make  investments  in  inventory  of  materials,  with  limited  shelf-life,  in
advance of regulatory approval and based on preliminary commercial forecasting, and such inventory may not be used if timelines and supply
needs shift.

Our drug candidates and any drugs that we may develop may compete with other drug candidates and approved drugs for access to
manufacturing  facilities.  There  are  a  limited  number  of  manufacturers  that  operate  under  cGMP  regulations  and  that  might  be  capable  of
manufacturing for us. Any third-party manufacturer with which we contract will have other clients, and our relative importance as a customer
may adversely impact contractual terms or the performance of services in a satisfactory manner or on a timely basis.

Any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval
or  interrupt  commercial  distribution.  If  our  current  contract  manufacturers  cannot  perform  as  agreed,  we  may  be  required  to  replace  such
manufacturers causing additional costs and delays in identifying and qualifying any such replacement. If a new contract manufacturer is not
successful  in  replicating  the  product  or  experiences  delays,  or  if  regulatory  authorities  impose  unforeseen  requirements  with  respect  to
product  comparability  from  multiple  manufacturing  sources,  we  may  experience  delays  in  clinical  development  or  an  interruption  in  our
commercial supply. No assurance can be given that any new manufacturer will be successful or that material manufactured by a new

58

 
 
 
 
Table of Contents

manufacturer will perform comparably to UKONIQ or ublituximab as manufactured to date or that the relevant regulatory agencies will agree
with our interpretation of comparability. Any significant delays or gaps in supply of UKONIQ, ublituximab, or other product candidates may
adversely affect our clinical development program, our ability to commercialize any drugs that receive marketing approval on a timely and
competitive basis, and our future profit margins.

We  also  rely  on  other  third  parties  to  store  and  distribute  drug  supplies  for  our  clinical  trials  and  for  commercial  demand  for
UKONIQ  and  expect  to  continue  to  do  so  for  any  other  product  candidates  that  may  receive  approval,  including  ublituximab.  Any
performance failure on the part of our distributors could delay clinical development or marketing approval of any future product candidates or
commercialization of our products, producing additional losses and depriving us of potential product revenue.

The  third  parties  upon  whom  we  rely  for  the  supply  of  starting  materials,  intermediates,  active  pharmaceutical  ingredient  (API)/drug
substance, drug product, and other materials used in our drug candidates are our sole source of supply, and the loss or disruption of any
of these suppliers, including as a result of the COVID-19 pandemic, could significantly harm our business.

The  starting  materials,  intermediates,  API/drug  substance,  and  drug  product  used  in  many  of  our  drug  candidates  are  currently
supplied to us from single-source suppliers. Our ability to successfully develop our drug candidates, supply our drug candidates for clinical
trials  and  to  ultimately  supply  our  commercial  drugs  in  quantities  sufficient  to  meet  the  market  demand,  depends  in  part  on  our  ability  to
obtain starting materials, intermediates, API/drug substance, and drug product for these drugs in accordance with regulatory requirements and
in sufficient quantities for clinical testing and commercialization. It is expected that many of our manufacturing partners will be sole source
suppliers  from  single  site  locations  for  the  foreseeable  future.  Various  raw  materials,  components,  and  testing  services  required  for  our
products may also be single sourced. We are not certain that our single-source suppliers will be able to supply sufficient quantities of their
products or on the timelines necessary to meet our needs, either because of the nature of our agreements with those suppliers, our limited
experience  with  those  suppliers,  our  relative  importance  as  a  customer  to  those  suppliers,  international  political  conflicts  that  may  impact
trade or the supply chain within a particular region, public health emergencies such as the COVID-19 pandemic or natural disasters that may
cause those suppliers to stop work for a period of time or lead to a sudden increase in demand for selected materials resulting in short-term
unavailability  of  such  materials.  If  any  of  our  suppliers  ceases  its  operations  for  any  reason  or  is  unable  or  unwilling  to  supply  starting
materials,  intermediates,  API/drug  substance,  and  drug  product  in  sufficient  quantities  or  on  the  timelines  necessary  to  meet  our  needs,  it
could significantly and adversely affect our business, the supply of our drug candidates and our financial condition. In addition, if our current
or future supply of any of our products or product candidates should fail to meet specifications during its stability program there could be a
voluntary or mandatory product recall if the product is approved and, even in the absence of a recall, there could be significant interruption of
our supply of drug, which would adversely affect the clinical development and commercialization of the product.

The COVID-19 pandemic has caused strain on the global supply chain. Although the pandemic has not had a material adverse effect
on  our  supply  chain  to  date,  no  assurance  can  be  given  that  it  will  not  in  the  future  if  the  situation  persists  or  worsens.  UKONIQ  is
manufactured  in  India,  ublituximab  is  manufactured  in  South  Korea,  and  TG-1701  is  manufactured  in  China.  Each  of  these  countries
continues to be, or has been, subject to government-imposed quarantines and travel restrictions due to the COVID-19 pandemic, which, in
some  cases,  have  resulted  in  reduced  operations  at  manufacturing  and  research  locations  and  time-limited  shutdowns.  Our  contract
manufacturers  for  UKONIQ  and  ublituximab  are  continuing  operations  at  varying  levels  of  capacity.  We  have  worked  closely  with  our
contract  manufacturer  for  UKONIQ  to  plan  for  anticipated  commercial  supply  needs.  We  also  are  working  closely  with  our  contract
manufacturer  for  ublituximab  to  plan  for  our  anticipated  commercial  supply  needs  if  we  are  successful  in  obtaining  FDA  approval  of  the
product. In addition to potential disruptions at our contract manufacturers, there may be unfavorable changes in the availability or cost of raw
materials, intermediates or other materials that we need for clinical and commercial production, which may result in higher costs or supply
chain interruptions. We will continue to monitor the situation very closely with our contract manufacturers and suppliers.

We continually evaluate our supply chains to identify potential risks and needs for additional manufacturers and other suppliers for
the  production  of  our  products  and  product  candidates.  Establishing  additional  or  replacement  suppliers  for  the  API/drug  substance,  drug
product, and certain raw materials, if required, may not be accomplished quickly or at all and may involve significant expense. If we are able
to  find  a  replacement  supplier,  we  would  need  to  evaluate  and  qualify  such  replacement  supplier  and  its  ability  to  meet  quality  and
compliance  standards.  Any  change  in  suppliers  or  the  manufacturing  process  could  require  additional  regulatory  approval  and  result  in
operational  delays.  While  we  seek  to  maintain  adequate  inventory  of  materials  necessary  for  the  production  of  our  products  and  product
candidates,  any  supply  interruption  or  delay,  or  our  inability  to  identify  alternate  sources  at  acceptable  prices  in  a  timely  manner  could
impede,  delay,  limit  or  prevent  our  commercialization  and  development  efforts,  which  could  harm  our  business,  results  of  operations,
financial condition and prospects.

Because  we  have  in-licensed  UKONIQ  and  our  product  candidates  from  third  parties,  any  dispute  with  or  non-performance  by  our
licensors will adversely affect our ability to develop and commercialize the applicable product or product candidate.

Because  we  license  UKONIQ  and  our  product  candidates  from  third  parties  and  we  expect  to  continue  to  in-license  additional
product candidates, if there is any dispute between us and our licensor regarding our rights under a license agreement, our ability to develop
and  commercialize  the  applicable  product  or  product  candidate  may  be  adversely  affected.  Disputes  may  arise  with  the  third  parties  from
whom we license our products and product candidates for a variety of reasons, including:

● the scope of rights granted under the license agreement and other interpretation-related issues;
● the  extent  to  which  our  technology  and  processes  infringe  on  intellectual  property  of  the  licensor  that  is  not  subject  to  the

license agreement;

● the sublicensing of patent and other rights under our collaborative development relationships and obligations associated with

sublicensing;

● our diligence obligations under the license agreement and what activities satisfy those diligence obligations;
● the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and

us and our partners; and

● the priority of invention of patented technology.

In addition, the agreements under which we currently license UKONIQ and our product candidates from third parties are complex,
and certain provisions in such agreements may be susceptible to multiple interpretations, or may conflict in such a way that puts us in breach
of one or more agreements, which would make us susceptible to lengthy and expensive disputes with one or more of our licensing partners.
The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the
relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement,
either of which could have a material adverse effect on our business, financial condition, results of operations, and prospects. Moreover, if
disputes  over  intellectual  property  that  we  have  licensed  prevent  or  impair  our  ability  to  maintain  our  current  licensing  arrangements  on
commercially  acceptable  terms,  we  may  be  unable  to  successfully  develop  and  commercialize  the  affected  product  or  product  candidate,
which could have a material adverse effect on our business, financial conditions, results of operations, and prospects.

If conflicts arise between us and our future collaborators or strategic partners, these parties may act in a manner adverse to us and could
limit our ability to implement our strategies.

If conflicts arise between our future corporate or academic collaborators or strategic partners and us, the other party may act in a
manner adverse to us and could limit our ability to implement our strategies. Future collaborators or strategic partners, may develop, either
alone  or  with  others,  products  in  related  fields  that  are  competitive  with  the  products  or  potential  products  that  are  the  subject  of  these
collaborations.  Competing  products,  either  developed  by  the  collaborators  or  strategic  partners  or  to  which  the  collaborators  or  strategic
partners have rights, may result in the withdrawal of partner support for any future product candidates. Our current or future collaborators or
strategic  partners  may  preclude  us  from  entering  into  collaborations  with  their  competitors,  fail  to  obtain  timely  regulatory  approvals,
terminate their agreements with us prematurely, or fail to devote sufficient resources to the development and commercialization of products.
Any of these developments could harm any future product development efforts.

We may seek to establish additional collaborations, and if we are not able to establish them on commercially reasonable terms, we may
have to alter our development and commercialization plans.

Our drug development programs and the potential commercialization of our drug candidates will require substantial additional cash
to  fund  expenses.  For  some  of  our  drug  candidates,  we  may  decide  to  collaborate  with  additional  pharmaceutical  and  biotechnology
companies for the development and potential commercialization of those drug candidates.

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration
will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed
collaboration,  and  the  proposed  collaborator’s  evaluation  of  a  number  of  factors.  Those  factors  may  include  the  design  or  results  of  our
clinical trials, the likelihood of approval by the FDA or similar regulatory authorities outside the United States, the potential market for the
subject  product  candidate,  the  costs  and  complexities  of  manufacturing  and  delivering  such  product  candidate  to  patients,  the  potential  of
competing drugs, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such
ownership without regard to the merits of the challenge, and industry and market conditions generally. The collaborator may also consider
alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration
could be more attractive than the one with us for our product candidate. The terms of any additional collaborations or other arrangements that
we may establish may not be favorable to us.

60

 
 
 
 
 
  
Table of Contents

We  may  be  restricted  under  our  collaboration  agreements  from  entering  into  future  agreements  on  certain  terms  with  potential
collaborators. Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a significant number
of  recent  business  combinations  among  large  pharmaceutical  companies  that  have  resulted  in  a  reduced  number  of  potential  future
collaborators.

We may not be able to negotiate additional collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we
may  have  to  curtail  the  development  of  the  product  candidate  for  which  we  are  seeking  to  collaborate,  reduce  or  delay  its  development
program  or  one  or  more  of  our  other  development  programs,  delay  its  potential  commercialization  or  reduce  the  scope  of  any  sales  or
marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect
to  increase  our  expenditures  to  fund  development  or  commercialization  activities  on  our  own,  we  may  need  to  obtain  additional  capital,
which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our
product candidates or bring them to market and generate revenue from their sales.

Any  future  collaborations  that  we  enter  into  may  not  be  successful.  The  success  of  our  collaboration  arrangements  will  depend
heavily on the efforts and activities of our collaborators. Collaborators generally have significant discretion in determining the efforts and
resources  that  they  will  apply  to  these  collaborations.  Disagreements  between  parties  to  a  collaboration  arrangement  regarding  clinical
development  and  commercialization  matters  can  lead  to  delays  in  the  development  process  or  commercializing  the  applicable  product
candidate and, in some cases, termination of the collaboration arrangement. These disagreements can be difficult to resolve if neither of the
parties has final decision-making authority. Collaborations with pharmaceutical or biotechnology companies and other third parties often are
terminated or allowed to expire by the other party. Any termination or expiration of any future collaboration agreement could adversely affect
us financially or harm our business reputation.

Risks Relating to Our Intellectual Property

Our  success  depends  upon  our  ability  to  obtain  and  protect  our  intellectual  property  and  proprietary  technologies.  If  the  scope  of  our
patent  protection  obtained  is  not  sufficiently  broad,  our  competitors  could  develop  and  commercialize  technology  and  drugs  similar  or
identical to ours, and our ability to successfully commercialize our technology and drugs may be impaired.

Our commercial success in part depends on obtaining and maintaining patent protection and trade secret protection in the United
States and other countries with respect to any product we commercialize, including UKONIQ, our product candidates, their formulations and
uses and the methods we use to manufacture them, as well as successfully defending these patents against third-party challenges. We seek to
protect  our  proprietary  and  intellectual  property  position  by  filing  patent  applications  in  the  United  States  and  abroad  related  to  our  novel
technologies and product candidates, and by maintenance of our trade secrets through proper procedures. Because we in-license our products
and  product  candidates,  we  also  rely  on  our  licensors  to  protect  the  patent  and  other  intellectual  property  rights  necessary  for
commercialization.

We  will  only  be  able  to  protect  our  technologies  from  unauthorized  use  by  third  parties  to  the  extent  that  valid  and  enforceable
patents or trade secrets cover them in the market they are being used or developed. The degree of patent protection we require to successfully
commercialize our products and product candidates may be unavailable or severely limited in some cases and may not adequately protect our
rights or permit us to gain or keep any competitive advantage. We cannot provide any assurances that any of our patents have, or that any of
our pending patent applications that mature into issued patents will include, claims with a scope sufficient to protect any of our products. In
addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States.

Furthermore, patents have a limited lifespan. In the United States, the natural expiration of a patent is generally twenty years after it
is filed. Various extensions may be available; however, the life of a patent, and the protection it affords, is limited. Given the amount of time
required for the development, testing and regulatory review of new drug candidates, patents protecting such candidates might expire before or
shortly after such candidates are commercialized. As a result, our owned patent portfolio may not provide us with adequate and continuing
patent protection sufficient to exclude others from commercializing drugs similar or identical to our product candidates, including generic
versions of such drugs.

Currently,  the  composition  of  matter  patent  for  ublituximab  and  UKONIQ  are  granted  in  both  the  United  States  and  EU,  among
other countries. A method of use patent covering the combination of ublituximab and UKONIQ has also been granted in the United States,
Europe, Japan, and several other territories. Additionally, several method of use patents for ublituximab and UKONIQ in various indications
and settings have also been applied for but have not yet been issued or have been issued in certain territories but not under all jurisdictions in
which such applications have been filed. There can be no guarantee that any patents for which an application has already been filed, nor

61

 
 
 
 
 
 
 
  
Table of Contents

any patents filed in the future, for cosibelimab, TG-1701 and TG-1801 or for our pre-clinical product candidates will be granted in any or all
jurisdictions in which they were filed, or that all claims initially included in such patent applications will be allowed in the final patent that is
issued. The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we or our partners
will  be  successful  in  protecting  our  product  candidates  by  obtaining  and  defending  patents,  or  what  the  scope  of  an  issued  patent  may
ultimately be.

These risks and uncertainties include the following:

● the patent applications that we or our licensors file may not result in any patents being issued;
● patents that may be issued or in-licensed may be challenged, invalidated, modified, revoked or circumvented, or otherwise may

not provide any competitive advantage;

● as of March 16, 2013, the United States converted from a first to invent to a first to file system. If we do not win the filing race,

we will not be entitled to inventive priority;

● our  competitors,  many  of  which  have  substantially  greater  resources  than  we  do,  and  many  of  which  have  made  significant
investments  in  competing  technologies,  may  seek,  or  may  already  have  obtained,  patents  that  will  limit,  interfere  with,  or
eliminate its ability to file new patent applications or make, use, and sell our potential products either in the United States or in
international markets;

● there  may  be  significant  pressure  on  the  United  States  government  and  other  international  governmental  bodies  to  limit  the
scope of patent protection both inside and outside the United States for disease treatments that prove successful as a matter of
public policy regarding worldwide health concerns; and

● countries other than the United States may have less restrictive patent laws than those upheld by United States courts, allowing

foreign competitors the ability to exploit these laws to create, develop, and market competing products.

If  patents  are  not  issued  that  protect  our  products  or  product  candidates,  it  could  have  a  material  adverse  effect  on  our  financial

condition and results of operations.

In  addition,  the  patent  prosecution  process  is  expensive  and  time-consuming,  and  we  may  not  be  able  to  file  and  prosecute  all
necessary  or  desirable  patent  applications  at  a  reasonable  cost  or  in  a  timely  manner.  Further,  with  respect  to  some  of  the  pending  patent
applications covering our drug candidates, prosecution has yet to commence. Patent prosecution is a lengthy process, during which the scope
of the claims initially submitted for examination by the USPTO have been significantly narrowed by the time they issue, if at all. It is also
possible that we will fail to identify any patentable aspects of our research and development output and methodology, and, even if we do, an
opportunity to obtain patent protection may have passed. Given the uncertain and time-consuming process of filing patent applications and
prosecuting them, it is possible that our product(s) or process(es) originally covered by the scope of the patent application may have changed
or been modified, leaving our product(s) or process(es) without patent protection. Moreover, in some circumstances, we do not have the right
to control the preparation, filing and prosecution of patent applications, or to maintain the patents, covering technology that we license from
third parties. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of
our business. If our licensors or we fail to appropriately prosecute and maintain patent protection or trade secret protection for one or more
products or product candidates, our ability to develop and commercialize such drugs may be adversely affected and we may not be able to
prevent  competitors  from  making,  using  and  selling  competing  products.  This  failure  to  properly  protect  the  intellectual  property  rights
relating to these product candidates could impair our ability to compete in the market and adversely affect our ability to generate revenues
and  achieve  profitability,  which  would  have  a  material  adverse  effect  on  our  financial  condition  and  results  of  operations.  Furthermore,
should  we  enter  into  other  collaborations,  including  out-licensing  or  partnerships,  we  may  be  required  to  consult  with  or  cede  control  to
collaborators regarding the prosecution, maintenance and enforcement of licensed patents. Therefore, these patents and applications may not
be prosecuted and enforced in a manner consistent with the best interests of our business.

The  patent  position  of  biotechnology  and  pharmaceutical  companies  generally  is  highly  uncertain,  involves  complex  legal  and
factual questions, and has in recent years been the subject of much litigation. In addition, no consistent policy regarding the breadth of claims
allowed in pharmaceutical or biotechnology patents has emerged to date in the United States. The patent situation outside the United States is
even more uncertain. The laws of foreign countries may not protect our rights to the same extent as the laws of the United States, and we may
fail  to  seek  or  obtain  patent  protection  in  all  major  markets.  For  example,  European  patent  law  restricts  the  patentability  of  methods  of
treatment of the human body more than United States law does. Our pending and future patent applications may not result in patents being
issued which protect our technology or products, in whole or in part, or which effectively prevent others from commercializing competitive
technologies and products. Changes in either the patent laws or interpretation of the patent laws in the U.S. and other countries may diminish
the value of our patents or narrow the scope of our patent protection. For example, the federal courts of the United States have taken an

62

 
 
 
Table of Contents

increasingly  dim  view  of  the  patent  eligibility  of  certain  subject  matter,  such  as  naturally  occurring  nucleic  acid  sequences,  amino  acid
sequences and certain methods of utilizing same, which include their detection in a biological sample and diagnostic conclusions arising from
their  detection.  Such  subject  matter,  which  had  long  been  a  staple  of  the  biotechnology  and  biopharmaceutical  industry  to  protect  their
discoveries, is now considered, with few exceptions, ineligible in the first instance for protection under the patent laws of the United States.
Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in those licensed from a third-party.

In  addition,  U.S.  patent  laws  may  change,  which  could  prevent  or  limit  us,  our  subsidiaries,  or  our  licensors  from  filing  patent
applications or patent claims to protect products and/or technologies or limit the exclusivity periods that are available to patent holders, as
well as affect the validity, enforceability, or scope of issued patents. For example, on September 16, 2011, the Leahy-Smith America Invents
Act was signed into law. The Leahy-Smith Act includes a number of significant changes to United States patent law. These include changes
to transition from a first-to-invent system to a first-to-file system and to the way issued patents are challenged. The formation of the Patent
Trial and Appeal Board now provides a quicker and less expensive process for challenging issued patents.

We may be subject to a third-party pre-issuance submission of prior art to the USPTO, or become involved in opposition, derivation,
reexamination, inter parties review, post-grant review or interference proceedings challenging our patent rights or the patent rights of others.
The costs of these proceedings could be substantial, and it is possible that our efforts to establish priority of invention would be unsuccessful,
resulting  in  a  material  adverse  effect  on  our  U.S.  patent  position.  An  adverse  determination  in  any  such  submission,  patent  office  trial,
proceeding or litigation could reduce the scope of, render unenforceable, or invalidate, our patent rights, allow third parties to commercialize
our technology or products and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize
products  without  infringing  third-party  patent  rights.  In  addition,  if  the  breadth  or  strength  of  protection  provided  by  patents  and  patent
applications  for  our  drug  candidates  is  threatened,  it  could  dissuade  companies  from  collaborating  with  us  to  license,  develop  or
commercialize current or future product candidates.

The issuance of a patent does not foreclose challenges to its inventorship, scope, validity or enforceability. Therefore, our owned and
licensed patents may be challenged in the courts or patent offices in the U.S. and abroad. Such challenges may result in loss of exclusivity or
in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using
or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and products.
Given  the  amount  of  time  required  for  the  development,  testing  and  regulatory  review  of  new  product  candidates,  patents  protecting  such
product  candidates  might  expire  before  or  shortly  after  such  product  candidates  are  commercialized.  As  a  result,  our  owned  and  licensed
patent portfolio may not provide us with enough rights to exclude others from commercializing products similar or identical to ours.

Even if our patent applications issue as patents, and they are unchallenged, our issued patents and our pending patents, if issued, may
not provide us with any meaningful protection or prevent competitors from designing around our patent claims to circumvent our owned or
licensed  patents  by  developing  similar  or  alternative  technologies  or  drugs  in  a  non-infringing  manner.  For  example,  a  third  party  may
develop  a  competitive  drug  that  provides  benefits  similar  to  one  or  more  of  our  products  or  product  candidates  but  that  has  a  different
composition that falls outside the scope of our patent protection. If the patent protection provided by the patents and patent applications we
hold  or  pursue  with  respect  to  our  products  or  product  candidates  is  not  sufficiently  broad  to  impede  such  competition,  our  ability  to
successfully commercialize our products or product candidates could be negatively affected, which would harm our business.

In addition, we may in the future be subject to claims by our former employees or consultants asserting an ownership right in our
patents or patent applications, as a result of the work they performed on our behalf. Although we have entered into agreements with many of
our employees, consultants and advisors and any other third parties who have access to our proprietary know-how, information or technology
to assign or grant similar rights to their inventions to us, we cannot be certain that we have executed such agreements with all parties who
may have contributed to our intellectual property, nor can we be certain that our agreements with such parties will be upheld in the face of a
potential challenge, or that they will not be breached, for which we may not have an adequate remedy. An adverse determination in any such
submission  or  proceeding  may  result  in  loss  of  exclusivity  or  freedom  to  operate  or  in  patent  claims  being  narrowed,  invalidated  or  held
unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology
and  drugs,  without  payment  to  us,  or  could  limit  the  duration  of  the  patent  protection  covering  our  technology  and  drug  candidates.  Such
challenges may also result in our inability to manufacture or commercialize our products and product candidates without infringing third-
party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could
dissuade companies from collaborating with us to license, develop or commercialize current or future drug candidates.

Patent protection and other intellectual property protection are crucial to the success of our business and prospects, and there is a

substantial risk that such protections will prove inadequate.

 Obtaining and maintaining patent protection depends on compliance with various procedural, document submission, fee payment and
other  requirements  imposed  by  governmental  patent  agencies,  and  our  patent  protection  could  be  reduced  or  eliminated  for  non-
compliance with these requirements.

The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee
payment and other similar provisions during the patent application process. In addition, periodic maintenance fees on issued patents often
must be paid to the USPTO and foreign patent agencies over the lifetime of the patent. While an unintentional lapse can in many cases be
cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can
result  in  abandonment  or  lapse  of  the  patent  or  patent  application,  resulting  in  partial  or  complete  loss  of  patent  rights  in  the  relevant
jurisdiction.

Non-compliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to,
failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal
documents.  If  we  fail  to  maintain  the  patents  and  patent  applications  covering  our  drugs  or  procedures,  we  may  not  be  able  to  stop  a
competitor from marketing drugs that are the same as or similar to our products or product candidates, which would have a material adverse
effect on our business.

If we do not obtain patent term extensions under the Hatch-Waxman Amendments and similar foreign legislation extending the terms of
our licensed patents and any future patents we may own, our business may be materially harmed.

Depending  on  the  timing,  duration,  and  specifics  of  any  FDA  regulatory  approval  for  our  drug  candidates,  one  or  more  of  our
licensed U.S. patents or future U.S. patents that we may license or own may be eligible for limited patent term restoration under the Hatch-
Waxman Amendments. The Hatch-Waxman Amendments permit a patent term extension of up to five years as compensation for patent term
lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond 14 years from
the date of product approval by the FDA, and only one patent covering the approved product may be extended.

The  application  for  a  patent  term  extension  is  subject  to  approval  by  the  USPTO,  in  conjunction  with  the  FDA.  We  may  not  be
granted  an  extension  because  of,  for  example,  failing  to  apply  within  applicable  deadlines,  failing  to  apply  prior  to  expiration  of  relevant
patents  or  otherwise  failing  to  satisfy  applicable  requirements.  Moreover,  the  applicable  time  period  or  the  scope  of  the  patent  protection
afforded could be less than we request. If we are unable to obtain patent term extension or any term of such extension is less than we request,
the period during which we will have the right to exclusively market our product will be shortened and our competitors may obtain earlier
approval of competing products, and our ability to generate revenues could be materially adversely affected.

We may not be able to enforce our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on drug candidates throughout the world would be prohibitively expensive. Competitors
may use our licensed and owned technologies in jurisdictions where we have not licensed or obtained patent protection to develop their own
products and, further, may export otherwise infringing products to territories where we may obtain or license patent protection, but where
patent enforcement is not as strong as that in the United States. These products may compete with our products in jurisdictions where we do
not have any issued or licensed patents and any future patent claims or other intellectual property rights may not be effective or sufficient to
prevent them from so competing.

Moreover,  our  ability  to  protect  and  enforce  our  intellectual  property  rights  may  be  adversely  affected  by  unforeseen  changes  in
foreign  intellectual  property  laws.  Additionally,  laws  of  some  countries  outside  of  the  United  States  and  Europe  do  not  afford  intellectual
property protection to the same extent as the laws of the United States and Europe. Many companies have encountered significant problems
in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems of some countries, including India,
China  and  other  developing  countries,  do  not  favor  the  enforcement  of  patents  and  other  intellectual  property  rights.  This  could  make  it
difficult for us to stop the infringement of our patents or the misappropriation of our other intellectual property rights. For example, many
foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. Consequently, we may not
be able to prevent third parties from practicing our inventions in certain countries outside the United States and Europe.

Proceedings to enforce our future patent rights, if any, in foreign jurisdictions could result in substantial cost and divert our resources
and attention from other aspects of our business. Moreover, such proceedings could put our patents at risk of being invalidated or interpreted
narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in

64

 
 
 
Table of Contents

any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be meaningful. Furthermore, while we intend to
protect our intellectual property rights in major markets for our products, we cannot ensure that we will be able to initiate or maintain similar
efforts in all jurisdictions in which we may wish to market our products. Accordingly, our efforts to protect our intellectual property rights in
such countries may be inadequate.

We  may  be  involved  in  lawsuits  to  protect  or  enforce  our  patents  or  the  patents  of  our  licensors,  which  could  be  expensive,  time
consuming and unsuccessful.

Competitors  may  infringe  our  patents  or  the  patents  of  our  licensors.  To  counter  infringement  or  unauthorized  use,  we  may  be
required to file infringement claims, which typically are very expensive, time-consuming and disruptive of day-to-day business operations.
Any claims we assert against accused infringers could provoke these parties to assert counterclaims against us alleging invalidity of our or
certain of our subsidiaries patents or that we infringe their patents; or provoke those parties to petition the USPTO to institute inter parties
review against the asserted patents, which may lead to a finding that all or some of the claims of the patent are invalid. In addition, in an
infringement proceeding, a court may decide that a patent of ours or our licensors is not valid or is unenforceable or may refuse to stop the
other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in
any  litigation  or  defense  proceedings  could  put  one  or  more  of  our  pending  patents  at  risk  of  being  invalidated,  held  unenforceable,  or
interpreted narrowly.

In patent litigation in the United States, defendant counterclaims challenging the validity, enforceability or scope of asserted patents
are  commonplace.  In  addition,  third  parties  may  initiate  legal  proceedings  against  us  to  assert  such  challenges  to  our  intellectual  property
rights. The outcome of any such proceeding is generally unpredictable. Grounds for a validity challenge could be an alleged failure to meet
any of several statutory requirements, including lack of novelty, obviousness or non-enablement. Patents may be unenforceable if someone
connected with prosecution of the patent withheld relevant information from the USPTO or made a misleading statement during prosecution.
It  is  possible  that  prior  art  of  which  we  and  the  patent  examiner  were  unaware  during  prosecution  exists,  which  could  render  our  patents
invalid. Moreover, it is also possible that prior art may exist that we are aware of but do not believe is relevant to our current or future patents,
but that could nevertheless be determined to render our patents invalid.

Competing  drugs  may  also  be  sold  in  other  countries  in  which  our  patent  coverage  might  not  exist  or  be  as  strong.  If  we  lose  a
foreign patent lawsuit, alleging our infringement of a competitor’s patents, we could be prevented from marketing our drugs in one or more
foreign countries. Any of these outcomes would have a materially adverse effect on our business.

In addition, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk
that some of our confidential information could be compromised by disclosure during this type of litigation. Furthermore, adverse results on
United States patents may affect related patents in our global portfolio. The adverse result could also put related pending patent applications
at risk of not issuing. Additionally, there could be public announcements of the results of hearings, motions or other interim proceedings or
developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of
our common stock.

Interference  proceedings  provoked  by  third  parties  or  brought  by  the  USPTO  may  be  necessary  to  determine  the  priority  of
inventions with respect to our patents or pending patent applications or those of our collaborators or licensors. An unfavorable outcome could
require us to cease using the related technology or to attempt to license rights to it from the prevailing party. The costs of these proceedings
could be substantial. As a result, the issuance, scope, validity, enforceability and commercial value of our or any of our respective licensors
patent  rights  are  highly  uncertain.  Our  business  could  be  harmed  if  the  prevailing  party  does  not  offer  us  a  license  on  commercially
reasonable  terms.  Litigation  or  interference  proceedings  may  fail  and,  even  if  successful,  may  result  in  substantial  costs  and  distract  our
management  and  other  employees.  We  may  not  be  able  to  prevent,  alone  or  with  our  licensors,  misappropriation  of  our  trade  secrets  or
confidential information, particularly in countries where the laws may not protect those rights as fully as in the United States.

We  may  not  have  sufficient  financial  or  other  resources  to  adequately  conduct  such  litigation  or  proceedings.  Some  of  our
competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial
resources and more mature and developed intellectual property portfolios. Accordingly, despite our efforts, we may not be able to prevent
third  parties  from  infringing  upon  or  misappropriating  or  from  successfully  challenging  our  intellectual  property  rights.  Uncertainties
resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to
compete in the marketplace.

If  we  or  our  partners  are  sued  for  infringing  intellectual  property  rights  of  third  parties,  it  will  be  costly  and  time  consuming,  and  an
unfavorable outcome in that litigation would have a material adverse effect on our business.

Our commercial success depends upon our ability and the ability of our collaborators to develop, manufacture, market and sell our
drug candidates and use our proprietary technologies without infringing the proprietary rights and intellectual property of third parties. The
biotechnology  and  pharmaceutical  industries  are  characterized  by  extensive  and  frequent  litigation  regarding  patents  and  other  intellectual
property rights. We may in the future become party to, or threatened with, adversarial proceedings or litigation regarding intellectual property
rights with respect to our drug candidates and technology, including interference proceedings before the USPTO.

Our competitors or other third parties may assert infringement claims against us, alleging that our drugs are covered by their patents.
Given the vast number of patents in our field of technology, we cannot be certain that we do not infringe existing patents or that we will not
infringe patents that may be granted in the future. Numerous United States and foreign issued patents and pending patent applications, which
are owned by third parties, exist in the fields in which we are developing products, some of which may be directed at claims that overlap with
the subject matter of our intellectual property. In addition, because patent applications can take many years to issue, there may be currently
pending applications, unknown to us, which may later result in issued patents that our product candidates or proprietary technologies may
infringe. Similarly, there may be issued patents relevant to our product candidates of which we are not aware. Publications of discoveries in
the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically
not published until 18 months after a first filing, or in some cases not at all. Therefore, we cannot know with certainty whether we or our
licensors were the first to make the inventions claimed in patents or pending patent applications that we own or licensed, or that we or our
licensors were the first to file for patent protection of such inventions.

We  are  aware  of  certain  patents  that  may  pose  issues  for  our  commercialization  of  our  drug  candidates.  If  we  decide  to  initiate
proceedings to challenge the validity of these patents in the future, we may be unsuccessful, as courts or patent offices in the United States
and abroad could uphold the validity of any such patents. If we were to challenge the validity of any issued United States patent in court, we
would need to overcome a statutory presumption of validity that attaches to every United States patent. This means that in order to prevail,
we would have to present clear and convincing evidence as to the invalidity of the patent’s claims. If we are unable to do so, we may be
forced to delay the launch of our product candidates or launch at the risk of litigation for patent infringement, which may have a material
adverse effect on our business and results of operations.

If a third-party claims that we or any collaborators of ours infringe their intellectual property rights, we may have to defend litigation
or administrative proceedings which may be costly whether we win or lose, and which could result in a substantial diversion of our financial
and management resources. If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license
from such third party to continue developing and marketing our drug candidates and technology. However, we may not be able to obtain any
required  license  on  commercially  reasonable  terms  or  at  all.  Even  if  we  were  able  to  obtain  such  a  license,  it  could  be  granted  on  non-
exclusive  terms,  thereby  providing  our  competitors  and  other  third  parties  access  to  the  same  technologies  licensed  to  us.  Without  such  a
license, we could be forced, including by court order, to cease developing and commercializing the infringing technology or drug candidates.
In addition, we could be found liable for monetary damages, including treble damages and attorney’s fees if we are found to have willfully
infringed such third-party patent rights. A finding of infringement could prevent us from commercializing our drug candidates or force us to
cease some of our business operations, which could materially harm our business.

No assurance can be given that patents issued to third parties do not exist, have not been filed, or could not be filed or issued, which
contain claims covering its products, technology or methods that may encompass all or a portion of our products and methods. Given the
number of patents issued and patent applications filed in our technical areas or fields, we believe there is a risk that third parties may allege
they have patent rights encompassing our products or methods.

Other product candidates that we may in-license or acquire could be subject to similar risks and uncertainties.

66

 
 
 
 
 
 
 
Table of Contents

We may need to license certain intellectual property from third parties, and such licenses may not be available or may not be available on
commercially reasonable terms.

A  third  party  may  hold  intellectual  property,  including  patent  rights  that  are  important  or  necessary  to  the  development  and
commercialization of our products. It may be necessary for us to use the patented or proprietary technology of third parties to commercialize
our products, in which case we would be required to obtain a license from these third parties, whom may or may not be interested in granting
such a license, on commercially reasonable terms, or our business could be harmed, possibly materially. For example, we engage extensively
with third parties, including academic institutions, to conduct non-clinical and clinical research on our product candidates. While we seek to
ensure  all  material  transfer  and  service  agreements  governing  this  research  provide  us  with  favorable  terms  covering  newly  generated
intellectual  property,  a  general  principle  under  which  much  of  this  research  with  academic  institutions  is  conducted  provides  third-party
ownership of newly generated intellectual property, with an exclusive option available for us to obtain a license to such intellectual property.
Through the conduct of this research, it is possible that valuable intellectual property could be developed by a third party, which we will then
need  to  license  in  order  to  better  develop  or  commercialize  our  products.  No  assurance  can  be  given  that  we  will  be  able  to  successfully
negotiate  such  a  license  on  commercially  reasonable  terms,  or  at  all.  Further,  should  we  fail  to  successfully  negotiate  a  license  to  such
intellectual property, most institutions are then free to license such intellectual property to any other third party, including potentially direct
competitors of ours. Should we fail to adequately secure a license to any newly generated intellectual property, our ability to successfully
develop or commercialize our products may be hindered, possibly materially.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position may be harmed.

In  addition  to  the  protection  afforded  by  patents,  we  rely  upon  unpatented  trade  secret  protection,  unpatented  know-how  and
continuing  technological  innovation  to  develop  and  maintain  our  competitive  position.  With  respect  to  the  building  of  our  proprietary
compound  library,  we  consider  trade  secrets  and  know-how  to  be  our  primary  intellectual  property.  We  seek  to  protect  our  proprietary
technology  and  processes,  in  part,  by  entering  into  confidentiality  agreements  with  our  collaborators,  scientific  advisors,  employees  and
consultants,  and  invention  assignment  agreements  with  our  consultants  and  employees.  We  may  not  be  able  to  prevent  the  unauthorized
disclosure or use of our technical know-how or other trade secrets by the parties to these agreements, however, despite the existence generally
of  confidentiality  agreements  and  other  contractual  restrictions.  Monitoring  unauthorized  uses  and  disclosures  is  difficult,  and  we  do  not
know whether the steps we have taken to protect our proprietary technologies will be effective. If any of the collaborators, scientific advisors,
employees and consultants who are parties to these agreements breaches or violates the terms of any of these agreements, we may not have
adequate  remedies  for  any  such  breach  or  violation,  and  we  could  lose  our  trade  secrets  as  a  result.  Enforcing  a  claim  that  a  third  party
illegally obtained and is using our trade secrets, like patent litigation, is expensive and time-consuming, and the outcome is unpredictable. In
addition, courts outside the United States are sometimes less willing to protect trade secrets.

Our trade secrets could otherwise become known or be independently discovered by our competitors. Competitors could purchase
our  drug  candidates  and  attempt  to  replicate  some  or  all  of  the  competitive  advantages  we  derive  from  our  development  efforts,  willfully
infringe  our  intellectual  property  rights,  design  around  our  protected  technology  or  develop  their  own  competitive  technologies  that  fall
outside  of  our  intellectual  property  rights.  If  any  of  our  trade  secrets  were  to  be  lawfully  obtained  or  independently  developed  by  a
competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to
compete  with  us.  If  our  trade  secrets  are  not  adequately  protected  so  as  to  protect  our  market  against  competitors’  drugs,  our  competitive
position could be adversely affected, as could our business.

Table of Contents

We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of
our competitors or are in breach of non-competition or non-solicitation agreements with our competitors.

We could in the future be subject to claims that we or our employees have inadvertently or otherwise used or disclosed alleged trade
secrets or other proprietary information of former employers or competitors. Although we try to ensure that our employees and consultants do
not use the intellectual property, proprietary information, know-how or trade secrets of others in their work for us, we may in the future be
subject to claims that we caused an employee to breach the terms of his or her non-competition or non-solicitation agreement, or that we or
these individuals have, inadvertently or otherwise, used or disclosed the alleged trade secrets or other proprietary information of a former
employer  or  competitor.  Litigation  may  be  necessary  to  defend  against  these  claims.  Even  if  we  are  successful  in  defending  against  these
claims, litigation could result in substantial costs and could be a distraction to management. If our defenses to these claims fail, in addition to
requiring us to pay monetary damages, a court could prohibit us from using technologies or features that are essential to our drug candidates,
if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of the former
employers. An inability to incorporate such technologies or features would have a material adverse effect on our business and may prevent us
from successfully commercializing our drug candidates. In addition, we may lose valuable intellectual property rights or personnel as a result
of  such  claims.  Moreover,  any  such  litigation  or  the  threat  thereof  may  adversely  affect  our  ability  to  hire  employees  or  contract  with
independent sales representatives. A loss of key personnel or their work product could hamper or prevent our ability to commercialize our
drug candidates, which would have an adverse effect on our business, results of operations and financial condition.

Risks Related to Our Business Organization and Governance, Strategy, Employees and Growth Management

If we fail to attract and keep key management, commercial, and clinical development personnel, we may be unable to successfully develop
or commercialize our product candidates.

We are highly dependent on the research and development, commercialization, manufacturing, quality, financial and legal expertise
of our senior management team as well as the other principal members of our management. Although we have entered into an employment
agreement with our chief executive officer and employment letters with our senior managers, each of our executive officers may terminate
their employment with us at any time. We do not maintain key person insurance for any of our executives or other employees. In addition, we
rely  on  consultants  and  advisors,  including  scientific  and  clinical  advisors,  to  assist  us  in  formulating  our  research  and  development  and
commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under
consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high
quality personnel, our ability to pursue our growth strategy will be limited.

Recruiting and retaining qualified scientific, clinical, manufacturing and sales and marketing personnel, particularly in MS, will be
critical to our success. The loss of the services of our chief executive officer or other key employees could impede the achievement of our
research,  development  and  commercialization  objectives  and  seriously  harm  our  ability  to  successfully  implement  our  business  strategy.
Furthermore, replacing key employees may be difficult and may take an extended period of time because of the limited number of individuals
in  our  industry  with  the  breadth  of  skills  and  experience  required  to  successfully  develop,  gain  regulatory  approval  of  and  commercialize
products. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on
acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We anticipate
that the uncertainty around the approvability of U2 in CLL and SLL stemming from the FDA plan to hold an ODAC meeting may make it
more  challenging  to  recruit  and  retain  qualified  personnel  across  functions.  See  “Risks  Related  to  the  Development  and
Commercialization  of  U2  and  UKONIQ.”    In  January  2022,  we  engaged  in  a  streamlining  exercise  across  the  Company,  reducing
headcount and external expenses. That streamlining effort may make retention of key personnel more difficult. If we are not able to attract
and retain the necessary personnel to accomplish our business objectives, we may experience constraints that will significantly impede the
achievement of our development and commercialization objectives, our ability to raise additional capital, and our ability to implement our
business strategy.

We will need to develop and expand our business, and we may encounter difficulties in managing this development and expansion, which
could disrupt our operations.

We  may  attempt  to  expand  our  business  by  acquiring  additional  businesses  or  drugs,  forming  strategic  alliances  or  creating  joint
ventures with third parties. We may encounter numerous difficulties in developing, manufacturing and marketing any new products resulting
from any such arrangement or transaction that may delay or prevent us from realizing their expected benefits. If we are unable to successfully
integrate such acquired businesses with our existing operations and company culture, we may never realize the benefits of such acquisitions
or  strategic  alliances.  We  cannot  assure  you  that,  following  any  such  transaction,  we  will  achieve  the  expected  synergies  to  justify  the
transaction.

Expanding our business will increase our operating needs. As of February 8, 2022, we had 291 full -time employees. We expect to
increase  our  number  of  employees  and  expand  the  scope  of  our  operations  focused  on  preparing  for  potential  commercialization  of
ublituximab  in  RMS.  In  addition,  in  the  event  the  FDA  approves  U2  for  the  treatment  of  CLL  and  SLL,  we  will  need  to  expand  our
operations supporting hematology. Our management and medical, commercial, and scientific personnel, systems and facilities currently in
place may not be adequate to support our anticipated future growth. 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. Also, our management may need to divert a disproportionate amount of its attention away from its day-to-day activities and devote
a  substantial  amount  of  time  to  managing  these  development  activities.  Due  to  our  limited  resources,  we  may  not  be  able  to  effectively
manage  the  expansion  of  our  operations  or  recruit  and  train  additional  qualified  personnel.  This  may  result  in  weaknesses  in  our
infrastructure, give rise to operational mistakes, loss of business opportunities, loss of employees and reduced productivity among remaining
employees. To accommodate growth, additional physical expansion of our operations in the future may lead to significant costs, including
capital  expenditures,  and  may  divert  financial  resources  from  other  projects,  such  as  the  development  of  our  drug  candidates.  If  our
management is unable to effectively manage our expected development and expansion, our expenses may increase more than expected, our
ability to generate or increase our revenue could be reduced and we may not be able to implement our business strategy. Our future financial
performance and our ability to commercialize our drug candidates, if approved, and compete effectively will depend, in part, on our ability to
effectively manage the future development and expansion of our business.

Additionally, to help manage the expanding needs, we may utilize the services of outside vendors or consultants to perform tasks
including clinical trial management, statistics and analysis, regulatory affairs, formulation development, chemistry, manufacturing, controls,
and other pharmaceutical development functions. Our growth strategy may also entail expanding our group of contractors or consultants to
implement these tasks going forward. Because we rely on a substantial number of consultants, effectively outsourcing many key functions of
our  business,  we  will  need  to  be  able  to  effectively  manage  these  consultants  to  ensure  that  they  successfully  carry  out  their  contractual
obligations  and  meet  expected  deadlines.  However,  if  we  are  unable  to  effectively  manage  our  outsourced  activities  or  if  the  quality  or
accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated,
and  we  may  not  be  able  to  obtain  regulatory  approval  for  our  product  candidates  or  otherwise  advance  our  business.  There  can  be  no
assurance  that  we  will  be  able  to  manage  our  existing  consultants  or  find  other  competent  outside  contractors  and  consultants  on
economically reasonable terms, or at all. If we are not able to effectively expand our organization by hiring new employees and expanding
our groups of consultants and contractors, we may be unable to successfully implement the tasks necessary to advance the commercialization
of UKONIQ and further develop and commercialize our product candidates and, accordingly, may not achieve our research, development and
commercialization goals.

Certain anti-takeover provisions in our governing documents and Delaware law could make a third-party acquisition of us difficult. This
could limit the price investors might be willing to pay in the future for our common stock.

Certain provisions in our amended and restated certificate of incorporation and restated bylaws may make it more difficult for a third
party to acquire us, or discourage a third party from attempting to acquire or control us and may limit the price that certain investors might be
willing to pay in the future for shares of our common stock. For example, our amended and restated certificate of incorporation allows us to
issue  preferred  stock  without  the  approval  of  our  stockholders,  the  issuance  of  which  could  decrease  the  amount  of  earnings  and  assets
available  for  distribution  to,  or  affect  the  rights  and  powers  (including  voting  rights)  of,  of  our  common  stockholders.  In  certain
circumstances,  such  issuance  could  have  the  effect  of  decreasing  the  market  price  of  our  common  stock.  In  addition,  our  restated  bylaws
eliminate the right of stockholders to call a special meeting of stockholders, which could make it more difficult for stockholders to effect
certain corporate actions. Any of these provisions could also have the effect of delaying or preventing a change in control.

On July 18, 2014, the Board of Directors declared a distribution of one right for each outstanding share of common stock. The rights
may have certain anti-takeover effects. The rights will cause substantial dilution to a person or group that attempts to acquire us on terms not
approved  by  the  Board  of  Directors  unless  the  offer  is  conditioned  on  a  substantial  number  of  rights  being  acquired.  However,  the  rights
should not interfere with any merger, statutory share exchange or other business combination approved by the Board of Directors since the
rights may be terminated by us upon resolution of the Board of Directors. Thus, the rights are intended to encourage persons who may seek to
acquire control of the Company to initiate such an acquisition through negotiations with the Board of Directors. However, the effect of the
rights may be to discourage a third party from making a partial tender offer or otherwise attempting to obtain a substantial equity position in
the  equity  securities  of,  or  seeking  to  obtain  control  of,  the  Company.  To  the  extent  any  potential  acquirers  are  deterred  by  the  rights,  the
rights may have the effect of preserving incumbent management in office.

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.

Under Section 382 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an ownership change (generally
defined as a greater than 50% change (by value) in the ownership of its equity over a three-year period), the corporation’s ability to use its
pre-change net operating loss carryforwards and certain other pre-change tax attributes to offset its post-change income may be limited. We
may have experienced such ownership changes in the past, and we may experience ownership changes in the future as a result of shifts in our
stock  ownership,  some  of  which  are  outside  our  control.  As  of  December  31,  2021,  we  had  federal  net  operating  loss  carryforwards  of
approximately $1,294 million, and our ability to utilize those net operating loss carryforwards could be limited by an ownership change as
described above, which could result in increased tax liability to us. In addition, pursuant to the Tax Act, we may not use net operating loss
carry-forwards to reduce our taxable income in any year by more than 80%, and we may not carry back any net operating losses to prior
years.  On  March  27,  2020,  the  “CARES  Act”  was  signed  by  the  U.S.  President.  Certain  provisions  of  the  CARES  Act  alter  the  rules
regarding net-operating losses for such losses arising in 2018, 2019 and 2020. Such losses may be carried back for five years. We cannot
assure you, however, of our ability to utilize these favorable offset rules within the applicable time period. These rules apply regardless of the
occurrence of an ownership change.

Certain of our executive officers, directors, principal stockholders and their affiliates maintain the ability to exercise significant influence
over our company and all matters submitted to stockholders for approval.

Certain of our executive officers, directors and stockholders own more than 5% of our outstanding common stock and, together with
their affiliates and related persons, beneficially own a significant percentage of our capital stock. If these stockholders were to choose to act
together, they would be able to influence our management and affairs and the outcome of matters submitted to our stockholders for approval,
including the election of directors and any sale, merger, consolidation, or sale of all or substantially all of our assets. This concentration of
voting  power  could  delay  or  prevent  an  acquisition  of  our  company  on  terms  that  other  stockholders  may  desire.  In  addition,  this
concentration of ownership might adversely affect the market price of our common stock by:

● delaying, deferring or preventing a change of control of us;
● impeding a merger, consolidation, takeover or other business combination involving us; or
● discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us.

Our internal information technology systems, or those of our third-party CROs, CMOs, or other contractors or consultants, may fail or
suffer  security  breaches,  which  could  result  in  a  material  disruption  of  our  drug  candidates’  development  programs  and  our
commercialization of any products for which we receive regulatory approval.

Despite the implementation of security measures, our internal information technology systems and those of our third-party CROs,
CMOs, and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, cyber-attacks or cyber-
intrusions over the Internet, natural disasters, terrorism, war and telecommunication and electrical failures. Although we have been the targets
of  cyber-attacks  and  cyber-intrusions,  the  impact  on  our  operations  and  financial  condition  has  not  been  material.  We  expect  such
cybersecurity  threats  to  continue  and  become  more  sophisticated.  A  significant  cyber-attack  or  cyber-intrusion  could  cause  our  systems  to
fail, leakage of confidential information, or business interruption, which could result in a material disruption of our operations, financial loss,
or  reputational  harm.  For  example,  the  loss  of  clinical  trial  data  for  our  drug  candidates  could  result  in  delays  in  our  regulatory  approval
efforts and significantly increase our costs to recover or reproduce the data. We have invested in protections and monitoring practices of our
data and information technology systems to reduce these risks and expect to continue do so as our information technology systems increase in
magnitude and complexity. However, there can be no assurance that our efforts and investments will prevent breakdowns or breaches in our
systems that could adversely affect our business.

Unfavorable global economic conditions could adversely affect our business, financial condition or results of operations.

Our  results  of  operations  could  be  adversely  affected  by  general  conditions  in  the  global  economy  and  in  the  global  financial
markets. For example, the COVID-19 pandemic has caused extreme volatility and disruptions in the capital and credit markets. A severe or
prolonged economic downturn could result in a variety of risks to our business, including, weakened demand for our drug candidates and our
ability to raise additional capital when needed on acceptable terms, if at all. A weak or declining economy could also strain our suppliers,
possibly resulting in supply disruption, or cause our customers to delay making payments for our services.

Our employees, principal investigators, CROs, CMOs and consultants may engage in misconduct or other improper activities, including
non-compliance  with  regulatory  standards  and  requirements  and  insider  trading,  which  could  have  a  material  adverse  effect  on  our
business.

We  are  exposed  to  the  risk  that  our  employees,  principal  investigators,  CROs,  CMOs,  and  consultants  may  engage  in  fraudulent
conduct  or  other  illegal  activity.  Misconduct  by  these  parties  could  include  intentional  failures  to  comply  with  FDA  regulations,  provide
accurate information to the FDA, comply with manufacturing standards we have established, comply with federal and state healthcare fraud
and abuse laws and regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales,
marketing  and  business  arrangements  in  the  healthcare  industry  are  subject  to  extensive  laws  and  regulations  intended  to  prevent  fraud,
misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing,
discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Activities subject to
these laws also involve the improper use of information obtained in the course of clinical trials or creating fraudulent data in our pre-clinical
studies  or  clinical  trials,  which  could  result  in  regulatory  sanctions  and  cause  serious  harm  to  our  reputation.  We  have  adopted  a  code  of
ethics  applicable  to  all  of  our  employees  and  have  implemented  a  compliance  program,  but  it  is  not  always  possible  to  identify  and  deter
misconduct  by  employees  and  other  third  parties,  and  the  precautions  we  take  to  detect  and  prevent  this  activity  may  not  be  effective  in
controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming
from a failure to comply with these laws or regulations. In addition, we are subject to the risk that a person could allege such fraud or other
misconduct, even if none occurred. If any such actions are instituted against us, regardless of the outcome, our reputation and our business
may suffer. If we are not successful in defending ourselves or asserting our rights, those actions could lead to imposition of civil, criminal and
administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare
programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which
could adversely affect our ability to operate our business.

We may acquire businesses or drugs, or form strategic alliances, in the future, and we may not realize the benefits of such acquisitions.

We may acquire additional businesses or drugs, form strategic alliances or create joint ventures with third parties that we believe will
complement  or  augment  our  existing  business.  If  we  acquire  businesses  with  promising  markets  or  technologies,  we  may  not  be  able  to
realize  the  benefit  of  acquiring  such  businesses  if  we  are  unable  to  successfully  integrate  them  with  our  existing  operations  and  company
culture. We may encounter numerous difficulties in developing, manufacturing and marketing any new products resulting from a strategic
alliance or acquisition that delay or prevent us from realizing their expected benefits or enhancing our business. We cannot assure you that,
following any such acquisition, we will achieve the expected synergies to justify the transaction.

We may be subject to adverse legislative or regulatory tax changes that could negatively impact our financial condition.

The  rules  dealing  with  U.S.  federal,  state  and  local  income  taxation  are  constantly  under  review  by  persons  involved  in  the
legislative process and by the IRS and the U.S. Treasury Department. Changes to tax laws (which changes may have retroactive application)
could adversely affect our stockholders or us. In recent years, many such changes have been made and changes are likely to continue to occur
in the future. We cannot predict whether, when, in what form, or with what effective dates, tax laws, regulations and rulings may be enacted,
promulgated or decided, which could result in an increase in our, or our stockholders, tax liability or require changes in the manner in which
we operate in order to minimize increases in our tax liability.

On  December  22,  2017,  legislation  commonly  referred  to  as  the  Tax  Act  was  signed  into  law  and  is  generally  effective  after
December  31,  2017.  The  Tax  Act  makes  significant  changes  to  the  United  States  federal  income  tax  rules  for  taxation  of  individuals  and
business entities. Most of the changes applicable to individuals are temporary and apply only to taxable years beginning after December 31,
2017 and before January 1, 2026. For corporations, the Tax Act reduces the top corporate income tax rate to 21% and repeals the corporate
alternative  minimum  tax,  limits  the  deduction  for  net  interest  expense,  limits  the  deduction  for  net  operating  losses  and  eliminates  net
operating loss carrybacks, modifies or repeals many business deductions and credits, shifts the United States toward a more territorial tax

system, and imposes new taxes to combat erosion of the U.S. federal income tax base. The Tax Act makes numerous other large and small
changes to the federal income tax rules that may affect potential investors and may directly or indirectly affect us. We continue to examine
the impact this tax reform legislation may have on our business. However, the effect of the Tax Act on us, whether adverse or favorable, is
uncertain, and may not become evident for some period of time. This document does not discuss such legislation or the manner in which it
might affect us or purchasers of our common stock. Prospective investors are urged to consult with their legal and tax advisors with respect to
the Tax Act and any other regulatory or administrative developments and proposals, and their potential effects on them based on their unique
circumstances.

Risks Related to the COVID-19 Pandemic

Major public health issues, and specifically the pandemic caused by COVID-19, could have an adverse impact on our financial condition
and results of operations and other aspects of our business.

In  December  2019,  a  novel  strain  of  coronavirus  which  causes  a  disease  referred  to  as  COVID-19,  was  first  detected  in  Wuhan,
China,  and  has  since  spread  around  the  world.  On  March  11,  2020,  the  World  Health  Organization  declared  that  the  rapidly
spreading  COVID-19  outbreak  had  evolved  into  a  pandemic.  In  response  to  the  pandemic,  many  governments  around  the  world  have
implemented a variety of control measures to reduce the spread of COVID-19, including travel restrictions and bans, instructions to residents
to practice social distancing, quarantine advisories, shelter-in-place orders and required closures of non-essential businesses.

The  COVID-19  pandemic  has  negatively  impacted  the  global  economy,  disrupted  global  supply  chains,  and  created  significant
volatility and disruption of financial markets. The extent to which the COVID-19 pandemic impacts our business and operating results will
depend  on  future  developments  that  are  highly  uncertain  and  cannot  be  accurately  predicted,  including  new  information  that  may  emerge
concerning  the rates of vaccination and efficacy of approved vaccines against the virus and any variant strains of the virus, other actions to
contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume if and when
the pandemic subsides, among others.

Should the COVID-19 pandemic persist or worsen and government restrictions continue, our business operations could be materially
delayed or interrupted. For instance, our ongoing clinical trials may be delayed or compromised; our ability to conduct new clinical trials may
be adversely impacted; our supply chain may be disrupted; health authority inspections of clinical sites or manufacturing facilities, or review
of our regulatory submissions may be delayed, and our commercialization efforts may be impacted. For example, during the course of the
pandemic the FDA has at points delayed both domestic and foreign facility inspections or conducted “remote interactive evaluations,” which
in a variety of circumstances are inclusive of Pre-Approval Inspections (PAIs). We expect the impact of COVID-19 on the FDA’s operations
will continue to evolve. It is unknown how long these disruptions could continue, were they to occur. Any delay in our clinical trials, PAIs or
in  the  regulatory  review  of  our  pending  BLA  submission  for  ublituximab  resulting  from  such  disruptions  could  materially  affect  the
development and commercialization of our product candidates.

We currently rely on third parties for certain functions or services in support of our clinical trials and key areas of our operations.
These  third  parties  include  contract  research  organizations  (CROs),  medical  institutions  and  clinical  investigators,  contract  manufacturing
organizations,  suppliers,  and  external  business  partners  supporting  commercialization  of  UKONIQ.  If  these  third  parties  themselves  are
adversely impacted by restrictions resulting from the COVID-19 outbreak, we will likely experience delays and/or realize additional costs. As
a result, our efforts to commercialize UKONIQ and obtain regulatory approvals for, and to commercialize, our product candidates may be
delayed or disrupted.

In addition, to protect the health of our workforce, starting in March 2020 we asked our office-based employees to work remotely.
Although many of the social distancing guidelines and capacity restrictions have been lifted, our office-based employees have continued to
work remotely as we plan for office reopening. Third parties on which we rely may also be continuing to use remote working arrangements
that  they  had  implemented  in  response  to  COVID-19.  Our  increased  reliance  on  personnel  working  remotely  may  negatively  impact
productivity, including our ability to monitor clinical trials, prepare regulatory applications, and conduct data analysis, or disrupt, delay, or
otherwise adversely impact our business. In addition, remote working could increase our cybersecurity risk and make us more susceptible to
communication  disruptions,  any  of  which  could  adversely  impact  our  business  operations  or  delay  necessary  interactions  with  local  and
federal regulators, manufacturing sites, research or clinical trial sites and contractors.

72

 
Table of Contents

Our ability to successfully commercialize UKONIQ, and any of our product candidates for which we in the future obtain regulatory
approval, also may be adversely impacted by restrictions and safety measures instituted due to COVID-19 and reductions in patient visits to
HCPs.  For  example,  reduced  access  to  healthcare  providers  and  institutions  as  a  result  of  COVID-19  safety  protocols  has  impacted  our
commercialization activities, including, the manner in which our field teams engage with healthcare providers and facilities. Our compliance
monitoring  and  oversight  of  interactions  and  communications  with  HCPs,  payors,  and  other  stakeholders  also  has  been  impacted  by  the
remote work environment.

The potential economic impact brought by and the duration of the pandemic may be difficult to assess or predict. However, it has
already caused, and is likely to result in further, significant disruption of global financial markets. It is likely that the pandemic will cause an
economic slowdown of potentially extended duration, and it is possible that it could cause a global recession. This disruption may reduce our
ability  to  access  capital  either  at  all  or  on  favorable  terms.  In  addition,  a  recession,  depression  or  other  sustained  adverse  market  event
resulting from the spread of COVID-19 could materially and adversely affect our business and the value of our common stock.

The ultimate impact of the current pandemic, or any other health epidemic, is highly uncertain and subject to change. We do not yet
know the full extent of potential delays or impacts on our business, our clinical trials, our research programs, healthcare systems or the global
economy  as  a  whole.  However,  these  effects  could  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of
operations.

To the extent the COVID-19 pandemic materially adversely affects our business and financial results, it may also have the effect of

significantly heightening many of the other risks described in this Risk Factors section.

The  COVID-19  pandemic  could  have  a  material  adverse  effect  on  our  clinical  development  program  if  the  pandemic  and  associated
government control measures continue.

The ongoing COVID-19 pandemic has presented substantial public health challenges and is impacting the global healthcare system,
including the conduct of clinical trials in the U.S. and other parts of the world. New variants continue to circulate, and uncertainty remains as
to whether additional restrictions may be implemented to address the spread of new variants. As a result of the COVID-19 pandemic, we may
encounter  delays  in  our  clinical  development  program.  The  majority  of  our  clinical  trials  involve  patients  with  cancer  or  those  receiving
ongoing  immunosuppressive  therapy  who  may  be  at  higher  risk  of  infection.  These  patients  are  thus  more  likely  to  be  subject  to  travel
restrictions and self-quarantining and may be more likely to withdraw from our clinical trials or unable to complete study assessments, which
may affect our ability to meet our projected timelines.

Further, we may not be able to complete our clinical trials that we initiated more recently and for which we have not yet completed
enrollment in the time frame that we had previously planned. In addition, the pandemic may adversely affect our ability to conduct new trials.
Some  factors  from  the  COVID-19  outbreak  that  may  delay  or  otherwise  adversely  affect  our  clinical  trial  programs,  as  well  as  adversely
impact our business generally, include:

● delays  or  difficulties  in  clinical  site  initiation,  including  difficulties  in  recruiting  and  retaining  clinical  sites,  impacts  on
compliance  with  clinical  study  protocols,  delays  enrolling  patients  in  our  clinical  trials,  decreased  enrollment  in  our  clinical
trials or increased rates of patients withdrawing from our clinical trials following enrollment, in each case, as a result of patients
contracting COVID-19, being forced to quarantine, experiencing reluctance to seek medical attention in a healthcare facility
setting, or otherwise not being able or willing to complete study assessments, particularly for older patients or others with a
higher risk of contracting COVID-19;
impacts to clinical results, including an increased number of observed adverse events, as a result of participants enrolled in our
clinical trials contracting COVID-19;
prioritization by healthcare providers, facilities, lawmakers, and regulators of COVID-19-related healthcare needs or, when the
pandemic subsides, to address the potential backlog of patients who have deferred medical procedures during the pendency of
the pandemic, which may reduce availability of professionals and resources for clinical trials in other disease areas;

●

●

● limitations  on  travel,  including  limitations  on  domestic  and  international  travel,  and  government-imposed  quarantines  or
restrictions  imposed  by  key  third  parties  that  could  interrupt  key  trial  activities,  such  as  clinical  trial  site  initiations  and
monitoring, which could impact the reliability or integrity of subject data and clinical study endpoints;
interruption of, or delays in receiving, supplies of our product candidates from our contract manufacturing organizations due to
staffing shortages, production slowdowns or stoppages or interruption in global shipping that may affect the transport of clinical
trial materials;

●

73

Table of Contents

●

disruptions and delays caused by potential workplace, laboratory and office closures and an increased reliance on employees
working from home across the healthcare system;

● disruptions  in  or  delays  to  regulatory  reviews,  responses,  inspections,  or  other  regulatory  activities,  including  review  of
marketing  applications  and  approvals  of  protocol  changes  or  amendments  to  SPAs,  as  a  result  of  the  spread  of  COVID-19
affecting the operations of the FDA or other regulatory authorities;

● changes  in  local  regulations  as  part  of  a  response  to  the  COVID-19  pandemic  which  may  require  us  to  change  the  ways  in

which clinical trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether;

● refusal of the FDA to accept data from clinical trials in affected geographies outside the United States; and
● negative effects on the quality, completeness, integrity, interpretability and cost of our clinical study data.

The potential disruptions discussed above and other consequences of the COVID-19 pandemic could result in missed study visits or
study procedures in our clinical trials, which could lead to an abundance of protocol deviations that impact  the  interpretability  of  the  trial
results. A significant number of deviations may call into question whether the execution of a clinical trial was consistent with the protocol,
which  is  of  particular  importance  where  study  designs  were  agreed  to  as  part  of  a  SPA  as  in  the  case  of  our  Phase  3  clinical  trial  for  the
combination  of  ublituximab  plus  UKONIQ  for  patients  with  CLL  (UNITY-CLL)  and  our  registration  program  for  ublituximab  in  RMS
(ULTIMATE  I  and  II).  In  extreme  cases,  significant  deviations  from  the  protocol  may  be  considered  a  violation  of  the  SPA  and  result  in
potential rescindment of the SPA agreement, which could adversely affect our ability to use the results of the impacted study to support a
future regulatory application.

We will continue to monitor the potential impact of COVID-19 on our clinical trial program, however, the full extent to which the
COVID-19 pandemic may directly or indirectly impact the progress of our current and planned trials will depend on future developments that
are highly uncertain and cannot be accurately predicted.

General Risks

Risks Related to Our Common Stock and Being a Publicly-Traded Company

Our stock price is, and we expect it to remain, volatile, which could limit investors’ ability to sell stock at a profit.

The trading price of our common stock has been and is likely to continue to be highly volatile and subject to wide fluctuations in

price in response to various factors, many of which are beyond our control. These factors include:

● publicity regarding actual or potential clinical results relating to products under development by our competitors or us;
● delay or failure in initiating, completing or analyzing nonclinical or clinical trials or the unsatisfactory design or results of these

trials;

● achievement or rejection of regulatory approvals by our competitors or us;
● announcements of technological innovations or new commercial products by our competitors or us;
● developments concerning proprietary rights, including patents;
● developments concerning our collaborations;
● regulatory developments in the United States and foreign countries;
● economic  or  other  crises  and  other  external  factors  such  as  the  disruptions  in  the  global  economy  caused  by  the  COVID-19

pandemic;

● period-to-period fluctuations in our revenues and other results of operations;
● failure to meet our revenue projections or guidance;
● changes in financial estimates by securities analysts; and
● sales of our common stock by us.

We will not be able to control many of these factors, and we believe that period-to-period comparisons of our financial results will

not necessarily be indicative of our future performance.

In addition, the stock market in general, and the market for biotechnology companies in particular, has experienced extreme price
and volume fluctuations that may have been unrelated or disproportionate to the operating performance of individual companies. These broad
market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance.

Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be
the sole source of gain for our stockholders.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to
finance  the  growth  and  development  of  our  business.  In  addition,  under  the  Amended  Loan  Agreement  with  Hercules,  we  are  currently
restricted from paying cash dividends, and we expect these restrictions to continue in the future. Furthermore, the terms of any future debt
agreements may continue to preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be the sole
source of gain for our stockholders for the foreseeable future.

An active trading market for our common stock may not be sustained, and investors may not be able to resell their shares at or above the
price they paid.

Although  we  have  listed  our  common  stock  on  the  Nasdaq  Capital  Market,  an  active  trading  market  for  our  shares  may  not  be
sustained. In the absence of an active trading market for our common stock, investors may not be able to sell their common stock at or above
the price at which they acquired their shares or at the time that they would like to sell. An inactive trading market may also impair our ability
to raise capital to continue to fund operations by selling shares and may impair our ability to acquire other companies or technologies by
using our shares as consideration.

If equity research analysts do not publish research or reports about our business or if they publish negative evaluations of or downgrade
our common stock, the price of our common stock could decline.

The trading market for our common stock relies in part on the research and reports that equity research analysts publish about us or
our  business.  We  do  not  control  these  analysts.  If  one  or  more  of  the  analysts  covering  our  business  downgrade  their  evaluations  of  our
common stock, the price of our common stock could decline. If one or more of these analysts cease to cover our common stock, we could
lose visibility in the market for our common stock, which in turn could cause our common stock price to decline.

We incur significant increased costs as a result of operating as a public company, and our management is required to devote substantial
time to compliance initiatives.

As a public company, we incur significant legal, accounting and other expenses under the Sarbanes-Oxley Act of 2002, as well as
rules  subsequently  implemented  by  the  SEC,  and  the  rules  of  any  stock  exchange  on  which  we  are  listed.  These  rules  impose  various
requirements  on  public  companies,  including  requiring  establishment  and  maintenance  of  effective  disclosure  and  financial  controls  and
appropriate  corporate  governance  practices.  Our  team  has  devoted  and  will  continue  to  devote  a  substantial  amount  of  time  to  these
compliance initiatives. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more
time-consuming and costly. For example, these rules and regulations make it more difficult and more expensive for us to obtain director and
officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain
the  same  or  similar  coverage.  As  a  result,  it  may  be  more  difficult  for  us  to  attract  and  retain  qualified  persons  to  serve  on  our  Board  of
Directors, our Board committees or as executive officers.

The Sarbanes-Oxley Act of 2002 requires, among other things, that we maintain effective internal control over financial reporting
and  disclosure  controls  and  procedures.  As  a  result,  we  are  required  to  periodically  perform  an  evaluation  of  our  internal  control  over
financial reporting to allow management to report on the effectiveness of those controls, as required by Section 404 of the Sarbanes-Oxley
Act. Additionally, our independent auditors are required to perform a similar evaluation and report on the effectiveness of our internal control
over  financial  reporting.  These  efforts  to  comply  with  Section  404  will  require  the  commitment  of  significant  financial  and  managerial
resources. While we anticipate maintaining the integrity of our internal control over financial reporting and all other aspects of Section 404,
we cannot be certain that a material weakness will not be identified when we test the effectiveness of our control systems in the future. If a
material weakness is identified, we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would
require additional financial and management resources, costly litigation or a loss of public confidence in our internal control over financial
reporting, which could have an adverse effect on the market price of our stock.

Volatility  in  the  price  of  our  common  stock  may  subject  us  to  securities  and  shareholder  derivative  litigation,  which  could  cause  us  to
incur substantial costs and divert management’s attention, financial resources and other company assets.

In the past, securities class action and shareholder derivative litigation has often been brought against a company following periods
of volatility in the market price of its securities. This risk is especially relevant for us because pharmaceutical companies have experienced
significant stock price volatility in recent years. Past lawsuits and any future lawsuits to which we may become a party are subject to inherent
uncertainties and will likely be expensive and time-consuming to investigate, defend and resolve, and will divert our management’s attention
and financial and other resources. The outcome of litigation is necessarily uncertain, and we could be forced to expend significant resources
in the defense of these and other suits, and we may not prevail. Any litigation to which we are a party may result in an onerous or unfavorable
judgment that may not be reversed upon appeal or in payments of substantial monetary damages or fines, or we may decide to settle this or
other lawsuits on similarly unfavorable terms, which could adversely affect our business, financial condition, results of operations or stock
price.

Future sales of our common stock, including by us or our directors and executive officers or shares issued upon the exercise of currently
outstanding options, could cause our stock price to decline.

A substantial portion of our outstanding common stock can be traded without restriction at any time. In addition, a portion of our

outstanding common stock is currently restricted as a result of federal securities laws, but can be sold at any time subject to applicable
volume limitations. As such, sales of a substantial number of shares of our common stock in the public market could occur at any time. These
sales, or the perception in the market that the holders of a large number of shares intend to sell shares, by us or others, could reduce the
market price of our common stock or impair our ability to raise adequate capital through the sale of additional equity securities. In addition,
we have a significant number of shares that are subject to outstanding options. The exercise of these options and the subsequent sale of the
underlying common stock could cause a further decline in our stock price. These sales also might make it difficult for us to sell equity
securities in the future at a time and at a price that we deem appropriate. We cannot predict the number, timing or size of future issuances or
the effect, if any, that any future issuances may have on the market price for our common stock.

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

The following discussion and analysis contains forward-looking statements about our plans and expectations of what may happen in
the future. Forward-looking statements are based on a number of assumptions and estimates that are inherently subject to significant risks and
uncertainties, and our results could differ materially from the results anticipated by our forward-looking statements as a result of many known
or  unknown  factors,  including,  but  not  limited  to,  those  factors  discussed  in  “Risk  Factors.”  See  also  the  “Special  Cautionary  Notice
Regarding Forward-Looking Statements” set forth at the beginning of this report.

You should read the following discussion and analysis in conjunction with “Item 8. Financial Statements and Supplementary Data,”

and our consolidated financial statements beginning on page F-1 of this report.

Overview

TG Therapeutics is a fully-integrated, commercial stage biopharmaceutical company focused on the acquisition, development and
commercialization of novel treatments for B-cell malignancies and autoimmune diseases. In addition to an active research pipeline including
five  investigational  medicines  across  these  therapeutic  areas,  we  have  received  accelerated  approval  from  the  U.S.  Food  and  Drug
Administration (FDA) for UKONIQ (umbralisib),  for  the  treatment  of  adult  patients  with  relapsed  or  refractory  marginal  zone  lymphoma
who  have  received  at  least  one  prior  anti-CD20-based  regimen  and  relapsed  or  refractory  follicular  lymphoma  who  have  received  at  least
three prior lines of systemic therapies. Currently, we have two programs in Phase 3 development for the treatment of patients with relapsing
forms of multiple sclerosis (RMS) and patients with chronic lymphocytic leukemia (CLL) and several investigational medicines in Phase 1
clinical  development.  We  also  actively  evaluate  complementary  products,  technologies  and  companies  for  in-licensing,  partnership,
acquisition and/or investment opportunities.

Following FDA approval of UKONIQ on February 5, 2021, we commenced commercial sales of UKONIQ in the US and began
generating  product  revenue.  During  the  year  ended  December  31,  2021,  our  only  sources  of  product  revenues  were  from  the  sales  of
UKONIQ. Product revenues are recorded net of estimates of variable consideration. For further discussion of our revenue recognition policy,
see “Critical Accounting Policies and Significant Judgements and Estimates” below.

Cost of product revenue consists primarily of materials and third-party manufacturing costs, as well as freight and royalties owed to
our  licensing  partner  for  UKONIQ  sales.  Based  on  our  policy  to  expense  costs  associated  with  the  manufacture  of  our  products  prior  to
regulatory  approval,  the  manufacturing  costs  of  UKONIQ  units  recognized  as  revenue  during  the  year  ended  December  31,  2021  were
expensed prior to receipt of FDA approval on February 5, 2021, and therefore are not included in costs of product revenue during the current
period.

Our  other  research  and  development  expenses  consist  primarily  of  expenses  relating  to  the  design,  development,  manufacture,
testing and enhancement of our drug candidates and technologies, milestone expenses related to in-licensing of new product candidates, fees
paid  to  consultants  and  outside  service  providers  for  clinical  and  laboratory  development,  personnel  expenses  and  other  facilities-related
expenses.  We  expense  our  research  and  development  costs  as  they  are  incurred.  Research  and  development  expenses  for  the  years  ended
December 31, 2021, 2020 and 2019 were approximately $198.5 million, $151.9 million and $148.4 million, respectively, excluding noncash
compensation expenses related to research and development.

The  following  table  sets  forth  the  research  and  development  expenses  per  project,  exclusive  of  noncash  compensation  expenses,  for  the
periods presented.

Revenues. Total revenue for the year ended December 31, 2021 increased compared to the comparable periods ended December 31,
2020 and 2019, due to net product revenues from U.S. sales of our sole commercial product, UKONIQ, which was approved by the FDA on
February 5, 2021.

Cost of Product Revenue. Cost of product revenue consists primarily of freight and royalties on net sales of UKNOIQ owed to our
licensing partner. During the year ended December 31, 2021, the cost of product revenue was $0.8 million. Based on our policy to expense
costs associated with the manufacture of our products prior to regulatory approval, the manufacturing costs of UKONIQ units recognized as
revenue during the year ended December 31, 2021 were expensed as research and development expenses prior to receipt of FDA approval on
February 5, 2021, and therefore are not included in costs of product revenue during the current period. We expect the cost of product revenues
to remain low, as we sell through certain inventory that was expensed prior to FDA approval of UKONIQ in February 2021.

Noncash  Compensation  Expense  (Research  and  Development).  Noncash  compensation  expense  (research  and  development)
related  to  equity  incentive  grants  totaled  $24.0  million  for  the  year  ended  December  31,  2021,  as  compared  to  $14.0  million  during  the
comparable  period  in  2020.  The  increase  in  noncash  compensation  expense  was  primarily  due  to  vesting  of  milestone-based  grants,  an
increase in research and development personnel and the vesting of grants at a higher stock price during the year ended December 31, 2021.

Other Research and Development Expense. Other research and development expense increased for the year ended December 31,

2021 by approximately $46.6 million to $198.5 million as compared to the comparable period ended December 31, 2020. The increase in
research and development expense is primarily attributable to increased manufacturing expense of approximately $34.4 million in preparation
for commercialization and for our Phase 3 clinical trials. Additionally, an increase in personnel expense of $9.5 million associated with the
buildout of our regulatory and late-stage development groups.

Table of Contents

Noncash  Compensation  Expense  (Selling,  General  and  Administrative).  Noncash  compensation  expense  (selling,  general  and
administrative) related to equity incentive grants totaled $37.2 million for the year ended December 31, 2021, as compared to $66.3 million
during the comparable period in 2020. The decrease in noncash compensation expense was primarily related to more milestone-based vesting
of restricted stock granted to executive personnel occurring during the year ended December 31, 2020.

Other  Selling,  General  and  Administrative.  Other  selling,  general  and  administrative  expenses  increased  for  the  year  ended
December 31, 2021 by approximately $49.3 million to $90.9 million as compared to the comparable period ended December 31, 2020. The
increase  in  selling,  general  and  administrative  expense  is  primarily  attributable  to  increased  personnel  and  other  selling,  general  and
administrative  costs  associated  with  execution  of  the  launch  of  UKONIQ  and  planning  for  the  potential  launches  of  U2  in  CLL  and
ublituximab in RMS.

Interest  Expense.  Interest  expense  for  the  year  ended  December  31,  2021  was  $5.6  million  compared  to  $6.3  million  for  the
comparable  period  ended  December  31,  2020.  The  $0.7  million  decrease  is  mainly  due  to  an  increase  in  interest  expense  related  to
administrative fees in connection with contract manufacturing costs during the year ended December 31, 2020.

Other Income. Other income increased by $1.9 million to $2.3 million for the year ended December 31, 2021, as compared to $0.5
million for the year ended December 31, 2020. The increase is mainly due to greater interest income and an increase in the change in fair
value of notes payable during the year ended December 31, 2021.

Revenues. License  revenue  was  approximately  $0.2  million  for  each  of  the  years  ended  December  31,  2020  and  2019.  License

revenue is related to the amortization of an upfront payment of $2.0 million associated with our license agreement with Ildong.

Noncash compensation expense (research and development). Noncash compensation expense (research and development) related

to equity incentive grants totaled $14.0 million for the year ended December 31, 2020, as compared to $5.8 million during the comparable

period in 2019. The increase in noncash compensation expense was primarily due to an increase in research and development personnel and
the vesting of grants with a higher stock price during the year ended December 31, 2020.

Other Research and Development Expense. Other research and development expense increased for the year ended December 31,
2020  by  approximately  $3.6  million  to  $151.9  million  compared  to  the  comparable  period  ended  December  31,  2019.  The  increase  in
research and development expense is primarily attributable to the achievement of various license agreement milestones, offset by a decrease
in manufacturing expense during the year ended December 31, 2020.

Noncash  Compensation  Expense  (General  and  Administrative).  Noncash  compensation  expense  (general  and  administrative)
related  to  equity  incentive  grants  totaled  $66.3  million  for  the  year  ended  December  31,  2020,  as  compared  to  $5.5  million  during  the
comparable  period  in  2019.  The  increase  in  noncash  compensation  expense  was  primarily  related  to  more  milestone-based  vesting  of
restricted stock granted to executive personnel occurring during the year ended December 31, 2020.

Other General and Administrative. Other general and administrative expenses increased for the year ended December 31, 2020 by
approximately $32.0 million to $41.5 million compared to the comparable period ended December 31, 2019. The increase was due primarily
to commercial costs, including personnel, incurred in preparation for the launch of UKONIQ.

Interest Expense. Interest expense increased by $1.0 million to $6.3 million for the year ended December 31, 2020, as compared to
expense of $5.3 million for year ended December 31, 2019. The increase is mainly due to interest expense related to administrative fees in
connection with contract manufacturing costs during the year ended December 31, 2020.

Other Income. Other income decreased by $1.0 million to $0.5 million for the year ended December 31, 2020, as compared to $1.5
million for the year ended December 31, 2019. The decrease in other income is mainly due to a decrease in interest income during the year
ended December 31, 2020. We expect our other income to remain at a comparable level during 2021.

LIQUIDITY AND CAPITAL RESOURCES

Our major sources of cash have been proceeds from private placement and public offering of equity securities, and from our loan
and security agreements executed with Hercules Capital, Inc. (Hercules) (see Note 6 for more information). In February of 2021, umbralisib,
now  referred  to  as  UKONIQ,  was  granted  accelerated  approval  in  the  United  States  for  the  treatment  of  adult  patients  with  relapsed  or
refractory MZL who have received at least one prior anti-CD20 based regimen and adult patients with relapsed or refractory FL who have
received  at  least  three  prior  lines  of  systemic  therapy.  Commercial  sales  of  UKONIQ  commenced  in  the  first  quarter  of  2021.  We  have
generated  limited  revenues  to  date  from  product  sales.  Even  with  the  commercialization  of  UKONIQ  and  the  potential  future
commercialization of our other drug candidates, we may not become profitable. Our ability to achieve profitability depends on many factors,
including  our  ability  to  generate  revenue,  our  ability  to  obtain  regulatory  approvals  for  our  drug  candidates,  our  ability  to  successfully
complete any post-approval regulatory obligations and our ability to successfully commercialize our drug candidates. We may continue to
incur substantial operating losses even as we begin to generate revenues from product sales.

As of December 31, 2021, we had $350.3 million in cash and cash equivalents, and investment securities. We anticipate that our
cash and cash equivalents, and investment securities as of December 31, 2021 will provide sufficient liquidity for more than a twelve-month
period from the date of filing this Annual Report on Form 10-K. The actual amount of cash that we will need to operate is subject to many
factors,  including,  but  not  limited  to,  the  timing,  design  and  conduct  of  clinical  trials  for  our  drug  candidates.  We  are  dependent  upon
significant future financing to provide the cash necessary to execute our current operations, including the commercialization of any of our
drug candidates.

Cash  used  in  operating  activities  for  the  year  ended  December  31,  2021  was  $295.6  million  as  compared  to  $214.5  million  for
the year ended December 31, 2020. The increase in cash used in operating activities was due primarily to increased expenditures associated
with execution of the launch of UKONIQ, our scale-up for manufacturing, ongoing clinical development programs and paydown of accounts
payable and accrued expenses.

For the year ended December 31, 2021, net cash used in investing activities was $0.3 million as compared to cash used in investing
activities of $24.5 million for the year ended December 31, 2020. The decrease in net cash used in investing activities was primarily due to
greater investment in short-term securities during the year ended December 31, 2020.

For  the  year  ended  December  31,  2021,  net  cash  provided  by  financing  activities  was  $41.4  million  as  compared  to  net  cash
provided by financing activities of $679.8 million for the year ended December 31, 2020. The decrease in net cash provided by financing
activities related to net proceeds from the issuance of common stock as part of our ATM program and public offerings that took place during
the year ended December 31, 2020.

ATM Program

In May 2017, we filed a shelf registration statement on Form S-3 (the 2017 S-3), which was declared effective in June 2017. Under
the  2017  S-3,  we  may  sell  up  to  a  total  of  $300  million  of  securities.  In  connection  with  the  2017  S-3,  we  entered  into  an  At-the-Market
Issuance Sales Agreement (the 2017 ATM) with Jefferies LLC, Cantor Fitzgerald & Co., FBR Capital Markets & Co., SunTrust Robinson
Humphrey, Inc., Raymond James & Associates, Inc., Ladenburg Thalmann & Co. Inc. and H.C. Wainwright & Co., LLC (each a 2017 Agent
and  collectively,  the  2017  Agents),  relating  to  the  sale  of  shares  of  our  common  stock.  Under  the  2017  ATM  we  paid  the  2017  Agents  a
commission rate of up to 3.0% of the gross proceeds from the sale of any shares of common stock.

During  the  year  ended  December  31,  2019,  we  sold  a  total  of  13,620,165  shares  of  common  stock  under  the  2017  ATM  for
aggregate  total  gross  proceeds  of  approximately  $99.3  million  at  an  average  selling  price  of  $7.29  per  share,  resulting  in  net  proceeds  of
approximately $97.5 million after deducting commissions and other transactions costs.

On September 5, 2019, we filed an automatic “shelf registration” statement on Form S-3 (the 2019 WKSI Shelf) as a “well-known
seasoned issuer” as defined in Rule 405 under the Securities Act, which registered an unlimited and indeterminate amount of debt or equity
securities for future issuance and sale. The 2019 WKSI Shelf was declared effective in September 2019. In connection with the 2019 WKSI
Shelf, we entered into an At-the-Market Issuance Sales Agreement (the 2020 ATM) with Jefferies LLC, Cantor Fitzgerald & Co. and B. Riley
Securities, Inc. (each a 2020 Agent and collectively, the 2020 Agents), relating to the sale of shares of our common stock. Under the 2020
ATM,  we  paid  the  2020  Agents  a  commission  rate  of  up  to  3.0%  of  the  gross  proceeds  from  the  sale  of  any  shares  of  common  stock.  In
November 2020, we entered into an At-the-Market Issuance Sales Agreement (the 2021 ATM) with the same terms and agents (each a 2021
Agent and collectively, the 2021 Agents) as the 2020 ATM.

During the year ended December 31, 2020, we sold a total of 8,528,286 shares of common stock under the 2020 ATM for aggregate

The  2019  WKSI  Shelf  is  currently  our  only  active  shelf-registration  statement.  We  may  offer  any  combination  of  the  securities
registered under the 2019 WKSI Shelf from time to time in response to market conditions or other circumstances if we believe such a plan of
financing is in the best interests of our stockholders. We believe that the 2019 WKSI Shelf provides us with the flexibility to raise additional
capital to finance our operations as needed.

Equity Financings

On  March  1,  2019,  we  completed  a  public  offering  of  4,100,000  shares  of  our  common  stock  (plus  a  30-day  underwriter
overallotment option to purchase up to an additional 615,000 shares of common stock, which was exercised) at a price of $5.87 per share.
Proceeds  from  this  offering,  including  the  overallotment,  after  underwriting  discounts  and  offering  expenses  were  approximately  $27.5
million.

On  December  22,  2019,  we  completed  a  securities  purchase  agreement  with  an  institutional  investor  in  which  we  agreed  to  sell

5,434,783 shares of our common stock at a price of $9.20 per share. Net proceeds from this offering were approximately $50.0 million.

In May 2020, we completed an underwritten public offering of 8,500,000 shares of our common stock (plus an underwriter option to
purchase up to an additional 1,275,000 shares of common stock, which was exercised) at a price of $18 per share. Net proceeds from this
offering,  including  the  overallotment,  were  approximately  $165.1  million,  net  of  underwriting  discounts  and  offering  expenses  of
approximately $10.8 million.

On  December  17,  2020,  we  completed  a  public  offering  of  6,320,000  shares  of  our  common  stock  (plus  a  30-day  underwriter
overallotment option to purchase up to an additional 948,000 shares of common stock, which was exercised) at a price of $43.50 per share.
Net proceeds from this offering, including the overallotment, were approximately $297.2 million after underwriting discounts and offering
expenses of approximately $19.0 million.

Debt Financings

On February 28, 2019 (the Closing Date), we entered into a term loan facility of up to $60.0 million (Term Loan) with Hercules
Capital, Inc. (Hercules), the proceeds of which were used for research and development programs and for general corporate purposes. The
Term  Loan  is  governed  by  a  loan  and  security  agreement,  dated  February  28,  2019  (the  Loan  Agreement),  which  provides  for  up  to  four
separate  advances.  The  first  advance  of  $30.0  million  was  drawn  on  the  Closing  Date.  An  additional  $30.0  million  was  available  with
different milestones and time points that have lapsed.

On  December  30,  2021  (the  First  Amendment  Closing  Date),  the  Company  entered  into  an  Amended  and  Restated  Loan  and
Security Agreement (the Amended Loan Agreement) with Hercules Capital, Inc. The Amended Loan Agreement amended the terms of the
Loan  Agreement  to,  among  other  things,  (i)  increase  the  aggregate  principal  amount  of  the  loan,  available  at  the  Company’s  option,  from
$60.0 million to $200.0 million (the Amended Term Loan), (ii) issue a first advance of $70.0 million drawn at the First Amendment Closing
date,  a  portion  of  which  was  used  to  refinance  the  current  outstanding  loan  balance  of  approximately  $7.8  million  and  pay  for  expenses
incurred  by  the  Lender  in  executing  the  agreements,  (iii)  change  the  draw  amounts  and  dates  available  in  Tranche  2  through  Tranche  4
including increasing the amount available under Tranche 2 subject to the achievement of performance milestones from $10.0 million to $20.0
million, increasing the amount available under Tranche 3 subject to the achievement of performance milestones from $10.0 million to $45.0
million, and increasing the amount under Tranche 4 subject to the approval of Hercules’ investment committee from $10.0 million to $65.0
million, (iv) extend the maturity date of the facility from the original March 1, 2022 to January 1, 2026, (v) reset and extend the interest only
period  from  April  1,  2021  to  February  1,  2025  and  extendable  to  August  1,  2025  subject  to  the  achievement  of  certain  performance
milestones, and (vi) modify the cash interest rate to be the greater of either (a) the “prime rate” as reported in The Wall Street Journal plus
2.15%, and (b) 5.40%. The performance milestones are based on achievement of certain U.S. Food and Drug Administration approvals and
impact  the  potential  extension  of  the  interest  only  period,  access  to  future  advances  under  the  Loan  Agreement  and  minimum  cash  levels
required under the Amended Loan Agreement.

The Amended Loan Agreement contains financial covenants from and after October 15, 2022 that require the Company to maintain
certain levels of unrestricted cash and additional financial covenants related to market capitalization and unrestricted cash commencing on
July 1, 2023 at any time when the Amended Term Loan advances made under the Amended Loan Agreement are greater than $70 million.

84

Table of Contents

The Amended Loan Agreement also contains warrant coverage of 2.95% of the total amount funded. A warrant (the Warrant) was
issued  by  the  Company  to  Hercules  to  purchase  115,042  shares  of  common  stock  with  an  exercise  price  of  $17.95  for  the  initial  amount
funded at closing. The Warrant shall be exercisable for seven years from the date of issuance. Hercules may exercise the Warrant either by (a)
cash or check or (b) through a net issuance conversion.

In addition, the Company is required to pay a final payment fee equal to 5.95% of the aggregate principal amount of the Term Loan

Advances.

The Company may, at its option, prepay the Amended Term Loan in full or in part, subject to a prepayment penalty equal to (i) 2.0%
of the principal amount prepaid if the prepayment occurs prior to the first anniversary of the First Amendment Closing Date, (ii) 1.5% of the
principal  amount  prepaid  if  the  prepayment  occurs  on  or  after  the  first  anniversary  and  prior  to  the  second  anniversary  of  the  First
Amendment Closing Date, and (iii) 1.0% of the principal amount prepaid if the prepayment occurs on or after the second anniversary and
prior to the third anniversary of the First Amendment Closing Date.

Leases

In October 2014, we entered into an agreement (the Office Agreement) with Fortress Biotech, Inc. (FBIO) to occupy approximately
45% of the 24,000 square feet of New York City office space leased by FBIO. The Office Agreement requires us to pay our respective share
of the average annual rent and other costs of the 15-year lease. We approximate an average annual rental obligation of $1.4 million under the
Office Agreement. We began to occupy this new space in April 2016, with rental payments beginning in the third quarter of 2016. At January
1,  2020,  we  recognized  a  lease  liability  and  corresponding  right  of  use  (ROU)  asset  based  on  the  present  value  of  the  remaining  lease
payments for all of our leased office spaces, the majority of which is comprised of our New York City office space. The present values of our
lease  liability  and  corresponding  ROU  asset  are  $11.3  million  and  $8.6  million,  respectively,  as  of  December  31,  2021.  Our  leases  have
remaining lease terms of 2 years to 10 years. One lease has a renewal option to extend the lease for an additional term of two years.

Under the Office Agreement, we agreed to pay FBIO our portion of the build-out costs, which have been allocated to us at the 45%
rate mentioned above. The allocated build-out costs have been recorded in Leasehold Interest, net on the Company’s consolidated balance
sheets and will be amortized over the 15-year term of the Office Agreement. The initial commitment period of the 45% rate was for a period
of three (3) years. We and FBIO currently determine actual office space utilization annually and if our utilization differs from the amount we
have been billed, we will either receive credits or be assessed incremental utilization charges. As of December 31, 2021, the allocation rate is
63% and will be evaluated again in August 2022 for the following rent year. Also, in connection with this lease, in October 2014 we pledged
$0.6  million  to  secure  a  line  of  credit  as  a  security  deposit  for  the  Office  Agreement,  which  has  been  recorded  as  restricted  cash  in  the
accompanying consolidated balance sheets. Additional collateral of $0.6 million was pledged in April 2018 to increase the letter of credit for
the office space.

In October 2019, we finalized a five-year lease for office space in New Jersey (the NJ Lease). We approximate an average annual
rental obligation of $0.3 million under the NJ Lease. We took possession of this space in October 2019, with rental payments beginning in
November 2019.

In  October  2021,  we  finalized  a  five-year  lease  for  office  space  in  North  Carolina  (the  NC  Lease).  We  approximate  an  average
annual  rental  obligation  of  $0.2  million  under  the  NC  Lease.  We  took  possession  of  this  space  in  February  2022,  with  rental  payments
beginning in April 2022.

Total rental expense was approximately $2.2 million, $2.7 million and 2.7 million for the years ended December 31, 2021, 2020 and

2019, respectively.

Future  minimum  lease  commitments  as  of  December  31,  2021  total,  in  the  aggregate,  approximately  $18.5  million  through
December 31, 2032. Our future minimum lease commitments include our office leases in New York, New Jersey and North Carolina as of
December 31, 2021.

OFF-BALANCE SHEET ARRANGEMENTS

We have not entered into any transactions with unconsolidated entities whereby we have financial guarantees, subordinated retained
interests,  derivative  instruments  or  other  contingent  arrangements  that  expose  us  to  material  continuing  risks,  contingent  liabilities,  or  any
other  obligations  under  a  variable  interest  in  an  unconsolidated  entity  that  provides  us  with  financing,  liquidity,  market  risk  or  credit  risk
support.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT JUDGMENTS AND ESTIMATES

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements,
which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements
requires  us  to  make  estimates  and  judgments  that  affect  the  reported  amount  of  assets  and  liabilities  and  related  disclosure  of  contingent
assets and liabilities at the date of our financial statements and the reported amounts of revenues and expenses during the applicable period.
Actual results may differ from these estimates under different assumptions or conditions.

We  define  critical  accounting  policies  as  those  that  are  reflective  of  significant  judgments  and  uncertainties  and  which  may
potentially result in materially different results under different assumptions and conditions. In applying these critical accounting policies, our
management uses its judgment to determine the appropriate assumptions to be used in making certain estimates. These estimates are subject
to an inherent degree of uncertainty. Our critical accounting policies include the following:

Revenue Recognition. Pursuant to 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  assess  the  goods  or  services  promised  within  each  contract  and  assess  whether  each  promised  good  or
service is distinct and determine those that are performance obligations. We then recognize as revenue the amount of the transaction price that
is allocated to the respective performance obligation when the performance obligation is satisfied.

Product Revenue, Net – The Company recognizes product revenues, net of variable consideration related to certain allowances and
accruals, when the customer takes control of the product, which is typically upon delivery to the customer. Product revenue is recorded at the
net sales price, or transaction price. The Company records product revenue reserves, which are classified as a reduction in product revenues,
to  account  for  the  components  of  variable  consideration.  Variable  consideration  includes  the  following  components,  which  are  described
below: chargebacks, government rebates, trade discounts and allowances, product returns, and co-payment assistance.

These reserves are based on estimates of the amounts earned or to be claimed on the related sales and are classified as reductions of
accounts receivable (if the amount is expected to be settled with a credit against the Company's customer account) or a liability (if the amount
is  expected  to  be  settled  with  a  cash  payment).  The  Company's  estimates  of  reserves  established  for  variable  consideration  are  calculated
based upon a consistent application of the expected value method, which is the sum of probability-weighted amounts in a range of possible
consideration amounts. These estimates reflect the Company's current contractual and statutory requirements, specific known market events
and trends, industry data, and forecasted customer buying and payment patterns. The amount of variable consideration that is included in the
transaction price may be subject to constraint and is included in net product revenues 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 received may
ultimately differ from the Company's estimates. If actual results vary, the Company adjusts these estimates, which could have an effect on
earnings  in  the  period  of  adjustment.  For  a  complete  discussion  of  the  accounting  for  product  revenue,  see  Note  1  –  Organization  and
Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements.

Stock Compensation. We have granted stock options and restricted stock to employees, directors and consultants, as well as warrants
to other third parties. For employee, director and consultant grants the value of each option award is estimated on the date of grant using the
Black-Scholes option-pricing model. The Black-Scholes model takes into account volatility in the price of our stock, the risk-free interest
rate, the estimated life of the option, the closing market price of our stock and the exercise price. We base our estimates of our stock price
volatility  on  the  historical  volatility  of  our  common  stock  and  our  assessment  of  future  volatility;  however,  these  estimates  are  neither
predictive nor indicative of the future performance of our stock. For purposes of the calculation, we assumed that no dividends would be

86

Table of Contents

paid during the life of the options and warrants. The estimates utilized in the Black-Scholes calculation involve inherent uncertainties and the
application of management judgment. In addition, because some of the options, restricted stock and warrants issued to employees, consultants
and other third parties vest upon the achievement of certain milestones, the total expense is uncertain. Compensation expense for such awards
that vest upon the achievement of milestones is recognized when the achievement of such milestones becomes probable.

Accrued  Research  and  Development  Expenses.  As  part  of  the  process  of  preparing  our  financial  statements,  we  are  required  to
estimate our accrued expenses. This process involves reviewing open contracts, communicating with our personnel to identify services that
have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we
have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly for services
performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our financial
statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service
providers and make adjustments, if necessary. Examples of estimated accrued research and development expenses include:

● fees paid to contract research organizations (CROs) in connection with clinical studies;
● fees paid to contract manufacturing organizations (CMOs);
● fees paid to trial sites in connection with clinical studies; and
● fees paid to vendors associated with licenses/milestones.

We base our expenses related to clinical studies on our estimates of the services received and efforts expended pursuant to contracts
with multiple CROs that conduct and manage clinical studies on our behalf. The financial terms of these agreements are subject to an initial
negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our
vendors will exceed the level of services provided and result in a prepayment of the clinical expense. 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  certain  service
fees, we estimate the time period over which services will be performed, enrollment of patients, number of sites activated and the level of
effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we
adjust the accrual or prepaid accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred,
our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and
may result in us reporting amounts that are too high or too low in any particular period.

RECENTLY ISSUED ACCOUNTING STANDARDS

Management  does  not  believe  that  any  recently  issued,  but  not  yet  effective,  accounting  pronouncements,  if  currently  adopted,

would have an effect on the Company’s financial statements.

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

The  primary  objective  of  our  investment  activities  is  to  preserve  principal  while  maximizing  our  income  from  investments  and
minimizing  our  market  risk.  We  currently  invest  in  government  and  investment-grade  corporate  debt  in  accordance  with  our  investment
policy, which we may change from time to time. The securities in which we invest have market risk. This means that a change in prevailing
interest rates, and/or credit risk, may cause the fair value of the investment to fluctuate. For example, if we hold a security that was issued
with a fixed interest rate at the then-prevailing rate and the prevailing interest rate later rises, the fair value of our investment will probably
decline.  As  of  December  31,  2021,  our  portfolio  of  financial  instruments  consists  of  cash  equivalents  and  short-term  interest-bearing
securities, including government debt and money market funds. The average duration of all of our held-to-maturity investments held as of
December 31, 2021, was less than 24 months. Due to the relatively short-term nature of these financial instruments, we believe there is no
material exposure to interest rate risk, and/or credit risk, arising from our portfolio of financial instruments.

DISCLOSURES.

Not applicable.

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation  of  Disclosure  Controls  and  Procedures.  As  of  December  31,  2021,  management  carried  out  an  evaluation,  under  the
supervision and with the participation of our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and
operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as
amended (the Exchange Act)). Our disclosure controls and procedures are designed to provide reasonable assurance that information we are
required to disclose in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the
time periods specified in applicable rules and forms. Based upon that evaluation, our Chief Executive and Chief Financial Officers concluded
that, as of December 31, 2021, our disclosure controls and procedures were effective.

Management’s  Annual  Report  on  Internal  Control  over  Financial  Reporting.  Our  management  is  responsible  for  establishing  and
maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) or Rule 15d-15(f) under the Exchange Act). Our
management assessed the effectiveness of our internal control over financial reporting as of December 31, 2021. In making this assessment,
our  management  used  the  criteria  established  in  Internal  Control  –  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring
Organizations  of  the  Treadway  Commission,  or  COSO  Framework.  Our  management  has  concluded  that,  as  of  December  31,  2021,  our
internal control over financial reporting was effective based on these criteria.

The  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2021  was  audited  by  KPMG  LLP,  our

independent registered public accounting firm, as stated in their report.

Changes  in  Internal  Control  Over  Financial  Reporting.  There  were  no  changes  in  our  internal  control  over  financial  reporting
during the quarter ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control
over financial reporting.

Limitations on the Effectiveness of Controls. Our management, including our Chief Executive Officer and Chief Financial Officer,
does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud.
A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the
control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of
controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can
provide absolute assurance that all control issues and instances of fraud, if any, within our Company have been detected.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
TG Therapeutics, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheet of TG Therapeutics, Inc. and subsidiaries (the Company) as of
December 31, 2021, the related consolidated statements of operations, changes in stockholders’ equity, and cash flows for the year ended
December 31, 2021, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial
statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021, and the results of its
operations and its cash flows for the year 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 (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 1, 2022
expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on
these consolidated financial statements 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 the consolidated financial statements are free of material misstatement, whether due to error or fraud.
Our audit included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated financial statements. Our audit also included evaluating the accounting principles
used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.
We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the consolidated 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 consolidated
financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical
audit matters.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
TG Therapeutics, Inc.:
Opinion on Internal Control Over Financial Reporting

We  have  audited  TG  Therapeutics,  Inc.  and  subsidiaries'  (the  Company)  internal  control  over  financial  reporting  as  of
December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring
Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over
financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the
Committee of Sponsoring Organizations of the Treadway Commission.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)
(PCAOB),  the  consolidated  balance  sheet  of  the  Company  as  of  December  31,  2021,  the  related  consolidated  statements  of  operations,
changes in stockholders’ equity, and cash flows for the year ended December 31, 2021, and the related notes (collectively, the consolidated
financial statements), and our report dated March 1, 2022 expressed an unqualified opinion on those consolidated financial statements.

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  Annual  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 of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the
risk  that  a  material  weakness  exists,  and  testing  and  evaluating  the  design  and  operating  effectiveness  of  internal  control  based  on  the
assessed risk. Our audit also included 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.

TG Therapeutics, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Unless the context requires otherwise, references in this report to “TG,” “Company,” “we,” “us” and “our” refer to TG Therapeutics, Inc.
and our subsidiaries.

NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

TG Therapeutics is a fully-integrated, commercial stage biopharmaceutical company focused on the acquisition, development and
commercialization of novel treatments for B-cell malignancies and autoimmune diseases. In addition to an active research pipeline including
five  investigational  medicines  across  these  therapeutic  areas,  we  have  received  accelerated  approval  from  the  U.S.  Food  and  Drug
Administration (FDA) for UKONIQ® (umbralisib), for the treatment of adult patients with relapsed or refractory marginal zone lymphoma
who  have  received  at  least  one  prior  anti-CD20-based  regimen  and  relapsed  or  refractory  follicular  lymphoma  who  have  received  at  least
three prior lines of systemic therapies. Currently, we have three programs in Phase 3 development for the treatment of patients with relapsing
forms of multiple sclerosis (RMS) and patients with chronic lymphocytic leukemia (CLL) and several investigational medicines in Phase 1
clinical  development.  We  also  actively  evaluate  complementary  products,  technologies  and  companies  for  in-licensing,  partnership,
acquisition and/or investment opportunities.

LIQUIDITY AND CAPITAL RESOURCES

We have incurred operating losses since our inception, and expect to continue to incur operating losses for the foreseeable future and

may never become profitable. As of December 31, 2021, we have an accumulated deficit of $1.3 billion.

Our major sources of cash have been proceeds from private placement and public offering of equity securities, and from our loan and
security agreements executed with Hercules Capital, Inc. (Hercules) (see Note 6 for more information). In February of 2021, umbralisib, now
referred to as UKONIQ, was granted accelerated approval in the United States for the treatment of adult patients with relapsed or refractory
MZL who have received at least one prior anti-CD20 based regimen and adult patients with relapsed or refractory FL who have received at
least three prior lines of systemic therapy. Commercial sales of UKONIQ commenced in the first quarter of 2021. We have generated limited
revenues to date from product sales. Even with the commercialization of UKONIQ and the potential future commercialization of our other
drug candidates, we may not become profitable. Our ability to achieve profitability depends on many factors, including our ability to generate
revenue, our ability to obtain regulatory approvals for our drug candidates, our ability to successfully complete any post-approval regulatory
obligations and our ability to successfully commercialize our drug candidates. We may continue to incur substantial operating losses even as
we begin to generate revenues from product sales.

As of December 31, 2021, we had $350.3 million in cash and cash equivalents, and investment securities. We anticipate that our
cash and cash equivalents, and investment securities as of December 31, 2021 will provide sufficient liquidity for more than a twelve-month
period from the date of filing this Annual Report on Form 10-K. The actual amount of cash that we will need to operate is subject to many
factors,  including,  but  not  limited  to,  the  timing,  design  and  conduct  of  clinical  trials  for  our  drug  candidates.  We  are  dependent  upon
significant future financing to provide the cash necessary to execute our current operations, including the commercialization of any of our
drug candidates.

Our common stock is quoted on the Nasdaq Capital Market and trades under the symbol “TGTX.”

RECENTLY ISSUED ACCOUNTING STANDARDS

Management  does  not  believe  that  any  recently  issued,  but  not  yet  effective,  accounting  pronouncements,  if  currently  adopted,

would have an effect on the Company’s financial statements.

Table of Contents

USE OF ESTIMATES

TG Therapeutics, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

The  preparation  of  financial  statements  in  conformity  with  U.S.  generally  accepted  accounting  principles  (GAAP)  requires
management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets
and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  during  the  applicable  reporting
period. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue, accrued clinical trial expenses and
stock-based compensation. Actual results could differ from those estimates. Such differences could be material to the financial statements.

CASH AND CASH EQUIVALENTS

We treat liquid investments with original maturities of less than three months when purchased as cash and cash equivalents.

RESTRICTED CASH

We record cash pledged or held in trust as restricted cash. As of December 31, 2021 and 2020, we have approximately $1.3 million

of restricted cash pledged to secure a line of credit as a security deposit for an Office Agreement (see Note 7).

INVESTMENT SECURITIES

Investment securities at December 31, 2021 and 2020 consist of short-term and long-term government securities. We classify these
securities as held-to-maturity. Held-to-maturity securities are those securities in which we have the ability and intent to hold the security until
maturity.  Held-to-maturity  securities  are  recorded  at  amortized  cost,  adjusted  for  the  amortization  or  accretion  of  premiums  or  discounts.
Premiums and discounts are amortized or accreted over the life of the related held-to-maturity security as an adjustment to yield using the
effective interest method.

A decline in the market value of any investment security below cost that is deemed to be other than temporary, results in a reduction
in the carrying amount to fair value. The impairment is charged to operations and a new cost basis for the security is established. Other-than-
temporary impairment charges are included in interest and other income (expense), net. Dividend and interest income are recognized when
earned.

CREDIT RISK

Financial  instruments  that  potentially  subject  the  Company  to  concentrations  of  credit  risk  consist  primarily  of  cash  and  cash
equivalents and short-term investments. The Company maintains its cash and cash equivalents and short-term investments with high-credit
quality financial institutions. At times, such amounts may exceed federally-insured limits.

REVENUE RECOGNITION

Pursuant to 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  assess  the  goods  or  services  promised  within  each  contract  and  assess  whether  each  promised  good  or
service is distinct and determine those that are performance obligations. We then recognize as revenue the amount of the transaction price that
is allocated to the respective performance obligation when the performance obligation is satisfied.

Notes to Consolidated Financial Statements

Product Revenue, Net – The Company recognizes product revenues, net of variable consideration related to certain allowances and
accruals, when the customer takes control of the product, which is typically upon delivery to the customer. Product revenue is recorded at the
net sales price, or transaction price. The Company records product revenue reserves, which are classified as a reduction in product revenues,
to  account  for  the  components  of  variable  consideration.  Variable  consideration  includes  the  following  components,  which  are  described
below: chargebacks, government rebates, trade discounts and allowances, product returns, and co-payment assistance.

These reserves are based on estimates of the amounts earned or to be claimed on the related sales and are classified as reductions of
accounts receivable (if the amount is expected to be settled with a credit against the Company's customer account) or a liability (if the amount
is  expected  to  be  settled  with  a  cash  payment).  The  Company's  estimates  of  reserves  established  for  variable  consideration  are  calculated
based upon a consistent application of the expected value method, which is the sum of probability-weighted amounts in a range of possible
consideration amounts. These estimates reflect the Company's current contractual and statutory requirements, specific known market events
and trends, industry data, and forecasted customer buying and payment patterns. The amount of variable consideration that is included in the
transaction price may be subject to constraint and is included in net product revenues 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 received may
ultimately differ from the Company's estimates. If actual results vary, the Company adjusts these estimates, which could have an effect on
earnings in the period of adjustment.

Chargebacks  and  Administrative  Fees:  Chargebacks  for  discounts  represent  the  Company's  estimated  obligations  resulting  from
contractual commitments to sell product to qualified healthcare providers and government agencies at prices lower than the list prices charged
to the customers who directly purchase the product from the Company. The customers charge the Company for the difference between what
the customers pay the Company for the product and the customers’ ultimate contractually committed or government required lower selling
price  to  the  qualified  healthcare  providers.  As  part  of  the  Company's  contractual  commitments  to  sell  product  to  qualified  healthcare
providers, the Company pays fees for administrative services, such as account management and data reporting.

Government Rebates: Government rebates consist of Medicare, Tricare, and Medicaid rebates. These reserves are recorded in the
same  period  the  related  revenue  is  recognized.  For  Medicare,  the  Company  also  estimates  the  number  of  patients  in  the  prescription  drug
coverage gap for whom it will owe a rebate under the Medicare Part D program.

GPO  and  Payor  Rebates:  The  Company  contracts  with  various  private  payor  organizations  and  group  purchasing  organizations
(GPO), primarily insurance companies, pharmacy benefit managers and clinics, for the payment of rebates with respect to utilization of our
product. The Company estimates these rebates and records such estimates in the same period the related revenue is recognized, resulting in a
reduction of product revenue and the establishment of a current liability.

Trade Discounts and Allowances: The Company provides its customers with discounts that are explicitly stated in the contracts and
are  recorded  in  the  period  the  related  product  revenue  is  recognized.  In  addition,  the  Company  also  receives  sales  order  management,
inventory management, and data services from its customers in exchange for certain fees.

Product Returns: Consistent with industry practice, the Company generally offers customers a limited right of return for product that
has been purchased from the Company. The Company estimates the amount of its product sales that may be returned by its customers and
records this estimate in the period the related product revenue is recognized. The Company currently estimates product return liabilities based
on data from similar products and other qualitative considerations, such as visibility into the inventory remaining in the distribution channel.

Subject  to  certain  limitations,  the  Company’s  return  policy  allows  for  eligible  returns  of  UKONIQ  for  credit  under  the  following

circumstances:

● receipt of damaged product;
● shipment errors that were a result of an error by the Company;
● expired product that is returned during the period beginning three months prior to the product’s expiration and ending six months after

the expiration date;

● product subject to a recall; and
● product that the Company, at its sole discretion, has specified can be returned for credit.

F-10

Table of Contents

TG Therapeutics, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

As of December 31, 2021, the Company has not received any returns.

Co-Payment  Assistance  Programs:  Co-payment  assistance  is  provided  to  qualified  patients,  whereby  the  Company  may  provide
financial  assistance  to  patients  with  prescription  drug  co-payments  required  by  the  patient's  insurance  provider.  Reserves  for  co-payment
assistance are recorded in the same period the related revenue is recognized.

ACCOUNTS RECEIVABLE

In  general,  accounts  receivable  consists  of  amounts  due  from  customers,  net  of  customer  allowances  for  cash  discounts,  product
returns and chargebacks. Our contracts with customers have standard payment terms. We analyze accounts that are past due for collectability,
and regularly evaluate the creditworthiness of our customers so that we can properly assess and respond to changes in their credit profiles. As
of December 31, 2021, we determined an allowance for expected credit losses related to outstanding accounts receivable was currently not
required based upon our review of contractual payment terms and individual customer circumstances.

COST OF PRODUCT REVENUE

Cost of product revenue consists primarily of materials and third-party manufacturing costs, as well as freight and royalties owed to
our  licensing  partner  for  UKONIQ  sales.  Based  on  our  policy  to  expense  costs  associated  with  the  manufacture  of  our  products  prior  to
regulatory  approval,  the  manufacturing  costs  of  UKONIQ  units  recognized  as  revenue  during  the  year  ended  December  31,  2021  were
expensed prior to receipt of FDA approval on February 5, 2021, and therefore are not included in costs of product revenue during the current
period.

INVENTORY

Prior to regulatory approval, we expense costs relating to the production of inventory as research and development expense in the
period incurred. Following regulatory approval, costs to manufacture those approved products will be capitalized. Inventories are stated at the
lower  of  cost  or  estimated  net  realizable  value  with  cost  based  on  the  first-in-first-out  method.  Inventory  that  can  be  used  in  either  the
production of clinical or commercial products is expensed as research and development costs when identified for use in clinical trials.

Prior to the approval of UKONIQ, all manufacturing and other potential costs related to the commercial launch of UKONIQ were

expensed to research and development expense in the period incurred.

RESEARCH AND DEVELOPMENT COSTS

Generally, research and development costs are expensed as incurred. Research and development expenses consist primarily of costs
incurred  to  third-party  service  providers  for  the  conduct  of  research,  preclinical  and  clinical  studies,  contract  manufacturing  costs,  license
milestone fees, personnel costs for our research and development employees, consulting, and other related expenses. We recognize research,
preclinical  and  clinical  study  expenses  based  on  services  performed,  pursuant  to  contracts  with  third-party  research  and  development
organizations  that  conduct  and  manage  research,  preclinical  and  clinical  activities  on  our  behalf.  We  accrue  these  expenses  based  on  the
progress or stage of completion of services and the contracted fees to be paid for such services. If the actual timing of the performance of
services or the level of effort varies from the original accrual, we will adjust the accrual accordingly. With respect to clinical trial costs, the
financial terms of these agreements are subject to an initial negotiation and vary from contract to contract. Payments under these contracts
may be uneven and depend on factors such as the achievement of certain events, the successful recruitment of patients, the completion of
portions of the clinical trial or similar conditions. As such, certain expense accruals related to clinical site costs are recognized based on the
degree of performance of the event or events specified in the specific clinical study or trial contract.

Prepaid research and development in our consolidated balance sheets includes, among other things, costs related to agreements with
CROs,  certain  costs  to  third-party  service  providers  related  to  development  and  manufacturing  services  as  well  as  clinical  development.
These agreements often require payments in advance of services performed or goods received. Accordingly, as of December 31, 2021 and
December 31, 2020, we recorded approximately $11.9 million and $5.2 million, respectively, in prepaid research and development related to
such advance agreements.

INCOME TAXES

TG Therapeutics, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future
tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and
their respective tax bases, operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect
on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. If the
likelihood of realizing the deferred tax assets or liability is less than “more likely than not,” a valuation allowance is then created.

We, and our subsidiaries, file income tax returns in the U.S. federal jurisdiction and in various states. We have tax net operating loss
carryforwards that are subject to examination for a number of years beyond the year in which they were generated for tax purposes. Since a
portion of these net operating loss carryforwards may be utilized in the future, many of these net operating loss carryforwards will remain
subject to examination. We recognize interest and penalties related to uncertain income tax positions in income tax expense. Refer to Note 8
for further information on impact of tax reform.

The Coronavirus Aid, Relief, and Economic Security Act of 2020 (“CARES Act”) was enacted on March 27, 2020 in response to
the economic fallout of the COVID-19 pandemic in the United States. There are several provisions of the CARES Act that were considered in
the December 31, 2021 year-end tax provision. However, the Company chose not to utilize any provisions or participate in certain programs
due to lack of a benefit to the Company.

STOCK-BASED COMPENSATION

The  Company  measures  employee  and  non-employee  stock-based  compensation  based  on  the  grant  date  fair  value  of  the  stock-
based compensation award. The Company grants stock options at exercise prices equal to the fair value of the Company’s common stock on
the date of grant, based on observable market prices. The Company uses the Black-Scholes option-pricing model to measure the fair value of
stock  option  awards.  We  recognize  all  stock-based  payments  to  employees  and  non-employee  directors  (as  compensation  for  service)  as
noncash compensation expense in the consolidated financial statements. Stock-based compensation expense recognized each period is based
on the value of the portion of stock-based payment awards that is ultimately expected to vest during the period. Forfeitures are recognized as
they occur.

In addition, because some of the options, restricted stock and warrants issued to employees, consultants and other third parties vest
upon  achievement  of  certain  milestones,  the  total  expense  is  uncertain.  Compensation  expense  for  such  awards  that  vest  upon  the
achievement of milestones is recognized when the achievement of such milestones becomes probable.

BASIC AND DILUTED NET LOSS PER COMMON SHARE

Basic net loss per share of our common stock is calculated by dividing net loss applicable to the common stock by the weighted-
average number of our common stock outstanding for the period. Diluted net loss per share of common stock is the same as basic net loss per
share of common stock since potentially dilutive securities from stock options, stock warrants and convertible preferred stock would have an
antidilutive effect either because we incurred a net loss during the period presented or because such potentially dilutive securities were out of
the money and the Company realized net income during the period presented. The amounts of potentially dilutive securities excluded from
the  calculation  were  13,280,608,  11,976,276  and  8,361,739  at  December  31,  2021,  2020  and  2019,  respectively.  During  the  years  ended
December 31, 2021, 2020 and 2019, the Company incurred a net loss; therefore, all of the securities are antidilutive and excluded from the
computation of diluted loss per share.

Long-lived assets are reviewed for potential impairment when circumstances indicate that the carrying value of long-lived tangible
and intangible assets with finite lives may not be recoverable. Management’s policy in determining whether an impairment indicator exists, a
triggering event, comprises measurable operating performance criteria as well as qualitative measures. If an analysis is necessitated by the
occurrence  of  a  triggering  event,  we  make  certain  assumptions  in  determining  the  impairment  amount.  If  the  carrying  amount  of  an  asset
exceeds its estimated future cash flows, an impairment charge is recognized.

Goodwill is reviewed for impairment annually, or earlier when events arise that could indicate that an impairment exists. We test for
goodwill  impairment  using  a  two-step  process.  The  first  step  compares  the  fair  value  of  the  reporting  unit  with  the  unit’s  carrying  value,
including  goodwill.  When  the  carrying  value  of  the  reporting  unit  is  greater  than  fair  value,  the  unit’s  goodwill  may  be  impaired,  and  the
second step must be completed to measure the amount of the goodwill impairment charge, if any. In the second step, the implied fair value of
the reporting unit’s goodwill is compared with the carrying amount of the unit’s goodwill. If the carrying amount is greater than the implied
fair value, the carrying value of the goodwill must be written down to its implied fair value. We will continue to perform impairment tests
annually,  at  December  31,  and  whenever  events  or  changes  in  circumstances  suggest  that  the  carrying  value  of  an  asset  may  not  be
recoverable. There was no impairment to goodwill as of December 31, 2021.

NOTE 2 - REVENUE RECOGNITION

Gross-to-Net Sales Adjustments

To date our only source of product revenue has been from the U.S. sales of UKONIQ, which we began shipping to our customers in
February 2021. We record our best estimate for sales discounts and allowances to which customers are likely to be entitled. The reconciliation
of gross product sales to net product sales by each significant category of gross-to-net adjustments was as follows for the year ended
December 31, 2021:

We  measure  certain  financial  assets  and  liabilities  at  fair  value  on  a  recurring  basis  in  the  financial  statements.  The  fair  value
hierarchy ranks the quality and reliability of inputs, or assumptions, used in the determination of fair value and requires financial assets and
liabilities carried at fair value to be classified and disclosed in one of the following three categories:

● Level 1 – quoted prices in active markets for identical assets and liabilities;

● Level 2 – inputs other than Level 1 quoted prices that are directly or indirectly observable; and

● Level 3 – unobservable inputs that are not corroborated by market data.

As of December 31, 2021 and 2020, the fair values of cash and cash equivalents, restricted cash, accounts receivable, and notes and

interest payable approximate their carrying value.

TG Therapeutics, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

At the time of our merger (we were then known as Manhattan Pharmaceuticals, Inc. (Manhattan)) with Ariston Pharmaceuticals, Inc.
(Ariston) in March 2010, Ariston issued $15.5 million of five-year 5% notes payable (the 5% Notes) in satisfaction of several note payable
issuances.  The  5%  Notes  and  accrued  and  unpaid  interest  thereon  are  convertible  at  the  option  of  the  holder  into  common  stock  at  the
conversion price of $1,125 per share. We have no obligations under the 5% Notes aside from the conversion feature.

NOTE 5 – STOCKHOLDERS’ EQUITY

Preferred Stock

TG Therapeutics, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Our amended and restated certificate of incorporation authorizes the issuance of up to 10,000,000 shares of preferred stock, $0.001
par value, with rights senior to those of our common stock, issuable in one or more series. Upon issuance, the Company can determine the
rights,  preferences,  privileges  and  restrictions  thereof.  These  rights,  preferences  and  privileges  could  include  dividend  rights,  conversion
rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the
designation of such series, any or all of which may be greater than the rights of common stock.

Stockholder Rights Plan

On  July  18,  2014,  we  adopted  a  stockholder  rights  plan.  The  stockholder  rights  plan  is  embodied  in  the  Stockholder  Protection
Rights Agreement dated as of July 18, 2014 (the Rights Agreement), between us and American Stock Transfer & Trust Company, LLC, as
rights agent (the Rights Agent).

Accordingly, the Board of Directors declared a distribution of one right (a “Right”) for each outstanding share of common stock, to
stockholders of record at the close of business on July 28, 2014, for each share of common stock issued (including shares distributed from
Treasury) by us thereafter and prior to the Separation Time (as defined in the Rights Agreement), and for certain shares of common stock
issued  after  the  Separation  Time.  Following  the  Separation  Time,  each  Right  entitles  the  registered  holder  to  purchase  from  us  one  one-
thousandth  (1/1,000)  of  a  share  of  Series  A  Junior  Participating  Preferred  Stock,  par  value  $0.001  per  share  (the  Preferred  Stock),  at  a
purchase  price  of  $100.00  (the  Exercise  Price),  subject  to  adjustment.  The  description  and  terms  of  the  Rights  are  set  forth  in  the  Rights
Agreement. Each one one-thousandth of a share of Preferred Stock has substantially the same rights as one share of common stock. Subject to
the terms and conditions of the Rights Agreement, Rights become exercisable ten days after the public announcement that a “Person” has
become an “Acquiring Person” (as each such term is defined in the Rights Agreement). Any Rights held by an Acquiring Person are void and
may not be exercised.

The Rights Agreement was approved by our Board of Directors on July 18, 2014. The Rights will expire at the close of business on

its ten-year anniversary, unless earlier exchanged or terminated by us.

Common Stock

Our  amended  and  restated  certificate  of  incorporation  authorizes  the  issuance  of  up  to  175,000,000  shares  of  $0.001  par  value

common stock.

In  May  2017,  we  filed  a  shelf  registration  statement  on  Form  S-3  (the  2017  S-3),  which  was  declared  effective  in  June  2017,
replacing the 2015 S-3. Under the 2017 S-3, we may sell up to a total of $300 million of securities. In connection with the 2017 S-3, we
entered  into  an  At-the-Market  Issuance  Sales  Agreement  (the  2017  ATM)  with  Jefferies  LLC,  Cantor  Fitzgerald  &  Co.,  FBR  Capital
Markets  &  Co.,  SunTrust  Robinson  Humphrey,  Inc.,  Raymond  James  &  Associates,  Inc.,  Ladenburg  Thalmann  &  Co.  Inc.  and  H.C.
Wainwright & Co., LLC (each a "2017 Agent" and collectively, the 2017 Agents), relating to the sale of shares of our common stock. Under
the 2017 ATM we pay the 2017 Agents a commission rate of up to 3.0% of the gross proceeds from the sale of any shares of common stock.

During  the  year  ended  December  31,  2019,  we  sold  a  total  of  13,620,165  shares  of  common  stock  under  the  2017  ATM  for
aggregate  total  gross  proceeds  of  approximately  $99.3  million  at  an  average  selling  price  of  $7.29  per  share,  resulting  in  net  proceeds  of
approximately $97.5 million after deducting commissions and other transactions costs.

On  March  1,  2019,  we  completed  a  public  offering  of  4,100,000  shares  of  our  common  stock  (plus  a  30-day  underwriter
overallotment option to purchase up to an additional 615,000 shares of common stock, which was exercised) at a price of $5.87 per share. Net
proceeds  from  this  offering,  including  the  overallotment,  were  approximately  $27.5  million  after  underwriting  discounts  and  offering
expenses of approximately $0.2 million.

TG Therapeutics, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

On September 5, 2019, we filed an automatic “shelf registration” statement on Form S-3 (the 2019 WKSI Shelf) as a “well-known
seasoned issuer” as defined in Rule 405 under the Securities Act, which registered an unlimited and indeterminate amount of debt or equity
securities for future issuance and sale. The 2019 WKSI Shelf was declared effective in September 2019. In connection with the 2019 WKSI
Shelf, we entered into an At-the-Market Issuance Sales Agreement (the 2020 ATM) with Jefferies LLC, Cantor Fitzgerald & Co. and B. Riley
Securities, Inc. (each a 2020 Agent and collectively, the 2020 Agents), relating to the sale of shares of our common stock. Under the 2020
ATM,  we  pay  the  2020  Agents  a  commission  rate  of  up  to  3.0%  of  the  gross  proceeds  from  the  sale  of  any  shares  of  common  stock.  In
November 2020, we entered into an At-the-Market Issuance Sales Agreement (the 2021 ATM) with the same terms and agents (each a 2021
Agent and collectively, the 2021 Agents) as the 2020 ATM.

During the year ended December 31, 2020, we sold a total of 8,528,286 shares of common stock under the 2020 ATM for aggregate
total  gross  proceeds  of  approximately  $187.5  million  at  an  average  selling  price  of  $21.99  per  share,  resulting  in  net  proceeds  of
approximately $184.2 million after deducting commissions and other transactions costs.

During the year ended December 31, 2020, we sold a total of 804,100 shares of common stock under the 2021 ATM for aggregate
total gross proceeds of approximately $33.9 million at an average selling price of $42.18 per share, resulting in net proceeds of approximately
$33.3 million after deducting commissions and other transactions costs.

During the year ended December 31, 2021, we sold a total of 72,000 shares of common stock under the 2021 ATM for aggregate
total gross proceeds of approximately $2.5 million at an average selling price of $34.25 per share, resulting in net proceeds of approximately
$2.4 million after deducting commissions and other transactions costs.

On  December  22,  2019,  we  completed  a  securities  purchase  agreement  with  an  institutional  investor  in  which  we  agreed  to  sell

5,434,783 shares of our common stock at a price of $9.20 per share. Net proceeds from this offering were approximately $50.0 million.

In May 2020, we completed an underwritten public offering of 8,500,000 shares of our common stock (plus an underwriter option to
purchase up to an additional 1,275,000 shares of common stock, which was exercised) at a price of $18 per share. Net proceeds from this
offering,  including  the  overallotment,  were  approximately  $165.1  million,  net  of  underwriting  discounts  and  offering  expenses  of
approximately $10.8 million.

On  December  17,  2020,  we  completed  a  public  offering  of  6,320,000  shares  of  our  common  stock  (plus  a  30-day  underwriter
overallotment option to purchase up to an additional 948,000 shares of common stock, which was exercised) at a price of $43.50 per share.
Net proceeds from this offering, including the overallotment, were approximately $297.2 million after underwriting discounts and offering
expenses of approximately $19.0 million.

The  2019  WKSI  Shelf  is  currently  our  only  active  shelf-registration  statement.  We  may  offer  any  combination  of  the  securities
registered under the 2019 WKSI Shelf from time to time in response to market conditions or other circumstances if we believe such a plan of
financing is in the best interests of our stockholders. We believe that the 2019 WKSI Shelf provides us with the flexibility to raise additional
capital to finance our operations as needed.

Treasury Stock

As  of  December  31,  2021  and  2020,  41,309  shares  of  common  stock  are  being  held  in  Treasury,  at  a  cost  of  approximately  $0.2

million, representing the fair market value on the date the shares were surrendered to the Company to satisfy employee tax obligations.

Equity Incentive Plans

The  TG  Therapeutics,  Inc.  Amended  and  Restated  2012  Incentive  Plan  (2012  Incentive  Plan)  was  approved  by  stockholders  in
June  2020.  Pursuant  to  this  amendment,  8,000,000  shares  were  added  to  the  2012  Incentive  Plan.  As  of  December  31,  2021  and  2020,

Total expense associated with the stock options was approximately $2.9 million, $6.0 million and $3.5 million during the years

ended December 31, 2021, 2020 and 2019, respectively. As of December 31, 2021, there was approximately $0.2 million of total
unrecognized compensation cost related to unvested time-based stock options, which is expected to be recognized over a weighted-average
period of 1.0 year. As of December 31, 2021, the stock options outstanding include options granted to both employees and non-employees
which are both time-based and milestone-based. Stock-based compensation for milestone-based options will be recorded if and when a
milestone occurs. We recognized stock-based compensation expense of $1.4 million during the year ended December 31, 2021 for these stock
options. We did not grant any options for the year ended December 31, 2021.

Total compensation expense associated with restricted stock grants was $58.4 million, $74.2 million and $7.8 million during

the years ended December 31, 2021, 2020 and 2019, respectively. As of December 31, 2021, there was approximately $50.7 million of total
unrecognized compensation expense related to unvested time-based restricted stock, which is expected to be recognized over a weighted-
average period of 1 year. This amount does not include, as of December 31, 2021, 4,016,281 shares of restricted stock outstanding which are
milestone-based and vest upon certain corporate milestones; and 1,088,750 shares of restricted stock outstanding issued to non-employees.
Milestone-based noncash compensation expense will be measured and recorded if and when a milestone becomes probable.

Warrants

The Company’s only outstanding warrants are the warrants issued to Hercules as part of our debt agreement to purchase 147,058 and
115,042 shares of common stock with exercise prices of $4.08 and $17.95, respectively. See Note 6 for further details. There will not be any
ongoing stock compensation expense volatility associated with these warrants.

NOTE 6 – LOAN PAYABLE

On February 28, 2019 (the Closing Date), we entered into a term loan facility of up to $60.0 million (Term Loan) with Hercules
Capital, Inc. (Hercules), the proceeds of which were used for research and development programs and for general corporate purposes. The
Term  Loan  is  governed  by  a  loan  and  security  agreement,  dated  February  28,  2019  (the  Loan  Agreement),  which  provides  for  up  to  four
separate  advances.  The  first  advance  of  $30.0  million  was  drawn  on  the  Closing  Date.  An  additional  $30.0  million  was  available  with
different milestones and time points that have lapsed.

On  December  30,  2021  (the  First  Amendment  Closing  Date),  the  Company  entered  into  an  Amended  and  Restated  Loan  and
Security Agreement (the Amended Loan Agreement) with Hercules Capital, Inc. The Amended Loan Agreement amended the terms of the
Loan  Agreement  to,  among  other  things,  (i)  increase  the  aggregate  principal  amount  of  the  loan,  available  at  the  Company’s  option,  from
$60.0 million to $200.0 million (the Amended Term Loan), (ii) issue a first advance of $70.0 million drawn at the First Amendment Closing
date,  a  portion  of  which  was  used  to  refinance  the  current  outstanding  loan  balance  of  approximately  $7.8  million  and  pay  for  expenses
incurred  by  the  Lender  in  executing  the  agreements,  (iii)  change  the  draw  amounts  and  dates  available  in  Tranche  2  through  Tranche  4
including increasing the amount available under Tranche 2 subject to the achievement of performance milestones from $10.0 million to

Notes to Consolidated Financial Statements

$20.0 million, increasing the amount available under Tranche 3 subject to the achievement of performance milestones from $10.0 million to
$45.0 million, and increasing the amount under Tranche 4 subject to the approval of Hercules’ investment committee from $10.0 million to
$65.0 million, (iv) extend the maturity date of the facility from the original March 1, 2022 to January 1, 2026, (v) reset and extend the interest
only  period  from  April  1,  2021  to  February  1,  2025  and  extendable  to  August  1,  2025  subject  to  the  achievement  of  certain  performance
milestones, and (vi) modify the cash interest rate to be the greater of either (a) the “prime rate” as reported in The Wall Street Journal plus
2.15%, and (b) 5.40%. The performance milestones are based on achievement of certain U.S. Food and Drug Administration approvals and
impact  the  potential  extension  of  the  interest  only  period,  access  to  future  advances  under  the  Loan  Agreement  and  minimum  cash  levels
required under the Amended Loan Agreement.

The Amended Loan Agreement contains financial covenants from and after October 15, 2022 that require the Company to maintain
certain levels of unrestricted cash and additional financial covenants related to market capitalization and unrestricted cash commencing on
July 1, 2023 at any time when the Amended Term Loan advances made under the Amended Loan Agreement are greater than $70 million.

The Amended Loan Agreement also contains warrant coverage of 2.95% of the total amount funded. A warrant (the Warrant) was
issued  by  the  Company  to  Hercules  to  purchase  115,042  shares  of  common  stock  with  an  exercise  price  of  $17.95  for  the  initial  amount
funded at closing. The Warrant shall be exercisable for seven years from the date of issuance. Hercules may exercise the Warrant either by (a)
cash or check or (b) through a net issuance conversion.

In addition, the Company is required to pay a final payment fee equal to 5.95% of the aggregate principal amount of the Term Loan

Advances.

The Company may, at its option, prepay the Amended Term Loan in full or in part, subject to a prepayment penalty equal to (i) 2.0%
of the principal amount prepaid if the prepayment occurs prior to the first anniversary of the First Amendment Closing Date, (ii) 1.5% of the
principal  amount  prepaid  if  the  prepayment  occurs  on  or  after  the  first  anniversary  and  prior  to  the  second  anniversary  of  the  First
Amendment Closing Date, and (iii) 1.0% of the principal amount prepaid if the prepayment occurs on or after the second anniversary and
prior to the third anniversary of the First Amendment Closing Date.

The  Company  evaluated  whether  the  Amended  Term  Loan  entered  into  in  December  2021  represented  a  debt  modification  or
extinguishment of the Term Loan in accordance with ASC 470-50, Debt – Modifications and Extinguishments. As a result of the repayment
and  retirement  of  the  Term  Loan,  the  Term  Loan  was  accounted  for  by  the  Company  under  the  extinguishment  accounting  model.  The
Company recorded a loss on extinguishment of debt of approximately $0.2 million on the Company’s statement of operations for the twelve
months ended December 31, 2021, representing the write-off of deferred financing costs.

The Company estimated the fair value of the Warrant using the Black-Scholes model based on the following key assumptions:

Exercise price
Common share price on date of issuance
Volatility

Notes to Consolidated Financial Statements

The Company incurred financing expenses of $7.4 million (including the fair value of the Warrant) related to the Amended Loan
Agreement which are recorded as debt issuance costs and as an offset to loan payable on the Company’s consolidated balance sheet. The debt
issuance costs are being amortized over the term of the debt using the straight-line method, which approximates the effective interest method,
and will be included in interest expense in the Company’s consolidated statements of operations. Amortization of debt issuance costs was
$1.1 million, $0.9 million and $0.8 million for the years ended December 31, 2021, 2020 and 2019, respectively. At December 31, 2021, the
remaining unamortized balance of debt issuance costs was $7.4 million.

The loan payable as of December 31, 2021 and 2020, is as follows:

In October 2014, we entered into an agreement (the Office Agreement) with Fortress Biotech, Inc. (FBIO) to occupy approximately
45% of the 24,000 square feet of New York City office space leased by FBIO. The Office Agreement requires us to pay our respective share
of the average annual rent and other costs of the 15-year lease. We approximate an average annual rental obligation of $1.4 million under the
Office Agreement. We began to occupy this new space in April 2016, with rental payments beginning in the third quarter of 2016. At January
1, 2019, we recognized a lease liability and corresponding ROU asset of $9.5 million and $8.1 million, respectively, based on the present
value of the remaining lease payments for all of our leased office spaces, the majority of which is comprised of our New York City office
space. The present values of our lease liability and corresponding ROU asset are $11.3 million and $8.6 million, respectively, as of December
31, 2021. Our leases have remaining lease terms of approximately 3 years to 10 years. One lease has a renewal option to extend the lease for
an additional term of five years.

The initial commitment period of the 45% rate was for a period of three (3) years. We and FBIO currently determine actual office
space utilization annually and if our utilization differs from the amount we have been billed, we will either receive credits or be assessed
incremental  utilization  charges.  As  of  December  31,  2021,  the  allocation  rate  is  63%  and  will  be  evaluated  again  in  August  2022  for  the
following rent year. Also in connection with this lease, in October 2014 we pledged $0.6 million to secure a line of credit as a security deposit
for the Office Agreement, which has been recorded as restricted cash in the accompanying consolidated balance sheets. Additional collateral
of $0.6 million was pledged in April 2018 to increase the letter of credit for the office space.

In October 2019, we finalized a five-year lease for office space in New Jersey (the NJ Lease). We approximate an average annual
rental obligation of $0.3 million under the NJ Lease. We took possession of this space in October 2019, with rental payments beginning in
November 2019.

In  October  2021,  we  finalized  a  five-year  lease  for  office  space  in  North  Carolina  (the  NC  Lease).  We  approximate  an  average
annual  rental  obligation  of  $0.2  million  under  the  NC  Lease.  We  took  possession  of  this  space  in  February  2022,  with  rental  payments
beginning in April 2022.

(*)  As  our  leases  do  not  provide  an  implicit  rate,  we  use  our  incremental  borrowing  rate  based  on  the  information  available  at
commencement  date  and  considering  the  term  of  the  lease  to  determine  the  present  value  of  lease  payments.  We  used  the  incremental
borrowing rate of 10.25% on February 28, 2019, for all operating leases, including those that commenced prior to that date.

NOTE 8 – INCOME TAXES

We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are determined based on

differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that
will be in effect when the differences are expected to reverse. A valuation allowance is established when necessary to reduce deferred tax
assets to the amount expected to be realized. In determining the need for a valuation allowance, management reviews both positive and
negative evidence, including current and historical results of operations, future income projections and the overall prospects of our business.
Based upon management's assessment of all available evidence, we believe that it is more-likely-than-not that the deferred tax assets will not
be realizable, and therefore, a valuation allowance has been established. The valuation allowance for deferred tax assets was approximately
$367.4 million and $276.7 million as of December 31, 2021 and 2020, respectively.

Notes to Consolidated Financial Statements

The Coronavirus Aid, Relief, and Economic Security Act of 2020 (“CARES Act”) was enacted on March 27, 2020 in response to
the economic fall out of the COVID-19 pandemic in the United States. The CARES Act allows employers to defer the deposit and payment
of the employer’s share of Social Security taxes during the payroll tax deferral period of March 27, 2020 through December 31, 2020. The
CARES Act provides for half of the deferred payroll taxes to be paid by December 31, 2021 and the second half to be paid by December 31,
2022. The Company did not participate in this deferral program.

As of December 31, 2021, we have U.S. net operating loss carryforwards of approximately $1.3 billion, research and development

credit carryforwards (“R&D credits”) of approximately $35.7 million and business interest expense carryforward of $9.8 million. For income
tax purposes, these NOLs and R&D credits will expire in various amounts through 2038. NOLs generated after 2017 and the business interest
expense carryforwards do not expire. The Tax Reform Act of 1986 contains provisions which limit the ability to utilize net operating loss
carryforwards and R&D credit carryforwards in the case of certain events including significant changes in ownership interests. The Exchange
Transaction with TG Bio may have resulted in a “change in ownership” as defined by IRC Section 382 of the Internal Revenue Code of 1986,
as amended. Additionally, stock issuance activities may have resulted in a “change in ownership” as defined by IRC Section 382 of the
Internal Revenue Code of 1986, as amended. Accordingly, a substantial portion of the Company’s NOLs above may be subject to annual
limitations in reducing any future year’s taxable income, and a substantial portion of the R&D Credit carryforwards may be subject to annual
limitations in reducing any future year’s tax.

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at

December 31, 2021 and 2020 are presented below.

We file income tax returns in the U.S Federal and various state and local jurisdictions. With certain exceptions, the Company is no
longer subject to U.S. Federal and state income tax examinations by tax authorities for years prior to 2018. However, NOLs and tax credits
generated from those prior years could still be adjusted upon audit.

The  Company  would  recognize  interest  and  penalties,  if  any,  to  uncertain  tax  position  in  income  tax  expense  in  the  statement  of
operations. There was no accrual for interest and penalties related to uncertain tax positions for 2021. We do not believe that there will be a
material change in our unrecognized tax positions over the next twelve months. All of the unrecognized tax benefits, if recognized, would be
offset by the valuation allowance

NOTE 9 – LICENSE AGREEMENTS

TG-1101 (Ublituximab)

In November 2012, we entered into an exclusive (within the territory) sublicense agreement with Ildong Pharmaceutical Co. Ltd.
(Ildong)  relating  to  the  development  and  commercialization  of  ublituximab  in  South  Korea  and  Southeast  Asia.  Under  the  terms  of  the
sublicense  agreement,  Ildong  has  been  granted  a  royalty  bearing,  exclusive  right,  including  the  right  to  grant  sublicenses,  to  develop  and
commercialize ublituximab in South Korea, Taiwan, Singapore, Indonesia, Malaysia, Thailand, Philippines, Vietnam, and Myanmar.

An upfront payment of $2.0 million, which was received in December 2012, net of $0.3 million of income tax withholdings, is being
recognized as license revenue on a straight-line basis over the life of the agreement, which is through the expiration of the last licensed patent
right or 15 years after the first commercial sale of a product in such country, unless the agreement is earlier terminated, and represents the
estimated period over which we will have certain ongoing responsibilities under the sublicense agreement. We recorded license revenue of
approximately  $0.2  million  for  each  of  the  years  ended  December  31,  2021,  2020  and  2019,  and,  at  December  31,  2021  and  2020,  have
deferred revenue of approximately $0.6 million and $0.8 million, respectively, associated with this $2 million payment (approximately $0.2
million of which has been classified in current liabilities at December 31, 2021 and 2020).

We may receive up to an additional $5.0 million in payments upon the achievement of pre-specified milestones. In addition, upon

commercialization, Ildong will make royalty payments to us on net sales of ublituximab in the sublicense territory.

In January 2012, we entered into an exclusive license agreement with LFB Biotechnologies, GTC Biotherapeutics and LFB/GTC

LLC, all wholly-owned subsidiaries of LFB Group, relating to the development of ublituximab (the LFB License Agreement). Under the

Notes to Consolidated Financial Statements

terms of the LFB License Agreement, we have acquired the exclusive worldwide rights (exclusive of France/Belgium) for the development
and commercialization of ublituximab. For the period ended December 31, 2021, we incurred approximately $7.0 million in expense related
to  the  achievement  of  certain  milestones  of  the  LFB  License  Agreement.  These  expenses  are  included  in  other  research  and  development
expenses  in  the  accompanying  consolidated  statements  of  operations.  As  of  December  31,  2021,  we  had  approximately  zero  recorded  in
accounts payable related to the LFB License Agreement.

LFB Group is eligible to receive payments of up to an aggregate of approximately $31.0 million upon our successful achievement of
certain clinical development, regulatory, and sales milestones, in addition to royalty payments on net sales of ublituximab at a royalty rate
that escalates from mid-single digits to high-single digits. The license will terminate on a country-by-country basis upon the expiration of the
last licensed patent right or 15 years after the first commercial sale of a product in such country, unless the agreement is earlier terminated (i)
by LFB if the Company challenges any of the licensed patent rights, (ii) by either party due to a breach of the agreement, or (iii) by either
party in the event of the insolvency of the other party.

TGR-1202 (Umbralisib or UKONIQ)

On  September  22,  2014,  we  exercised  our  option  to  license  the  global  rights  to  umbralisib,  thereby  entering  into  an  exclusive
licensing  agreement  (the  TGR-1202  License)  with  Rhizen  Pharmaceuticals,  SA  (Rhizen)  for  the  development  and  commercialization  of
umbralisib.

Under the terms of the TGR-1202 License, Rhizen received a $4.0 million cash payment and 371,530 shares of our common stock
as  an  upfront  license  fee.  For  the  year  ended  December  31,  2021,  we  paid  Rhizen  $12.0  million  as  part  of  a  primary  indication  approval
milestone  for  launch  of  product  in  the  US  in  accordance  with  the  terms  of  the  Umbralisib  License.  Rhizen  will  be  eligible  to  receive
additional approval and sales-based milestone payments in the aggregate of approximately $175 million payable upon approval in multiple
jurisdictions  for  up  to  two  oncology  indications  and  one  non-oncology  indication  and  attaining  certain  sales  milestones.  In  addition,  if
umbralisib  is  co-formulated  with  another  drug  to  create  a  new  product  (a  "New  Product"),  Rhizen  will  be  eligible  to  receive  similar
regulatory approval and sales-based milestone payments for such New Product. Additionally, Rhizen receives tiered royalties that escalate
from high single digits to low double digits on any net sales of umbralisib and any New Product. During the year ended December 31, 2021,
the Company recorded $0.5 million related to the worldwide royalty due under the Umbralisib License in cost of product revenue based on
U.S. sales of UKONIQ and as of December 31, 2021, $0.2 million in royalties were payable under the Umbralisib License. Rhizen shall also
be eligible to participate in sublicensing revenue, if any, based on a percentage that decreases as a function of the number of patients treated
in clinical trials following the exercise of the license option. Rhizen will retain global manufacturing rights to umbralisib, provided that they
are price competitive with alternative manufacturers. The license will terminate on a country-by-country basis upon the expiration of the last
licensed patent right or any other exclusivity right in such country, unless the agreement is earlier terminated (i) by us for any reason, or (ii)
by either party due to a breach of the agreement.

TG-1501: PDL1 (Cosibelimab)

In March 2015, we entered into a Global Collaboration Agreement (Collaboration Agreement) with Checkpoint for the development
and  commercialization  of  anti-PD-L1  and  anti-GITR  antibody  research  programs  in  the  field  of  hematological  malignancies.  The
Collaboration  Agreement  was  amended  in  June  2019  and  in  March  of  2020.  We  incurred  expenses  of  approximately  $0.1  million,  $1.1
million and $4.1 million for the years ended December 31, 2021, 2020 and 2019, respectively, the majority of which relates to manufacturing
expenses  and  milestone  payments  of  PD-L1.  The  relevant  expenses  are  recorded  in  other  research  and  development  in  the  accompanying
consolidated statements of operations.

TG-1601: BET

In  May  2016,  as  part  of  a  broader  agreement  with  Jubilant  Biosys  (Jubilant),  we  entered  into  a  sub-license  agreement  (JBET
Agreement) with Checkpoint Therapeutics, Inc. (Checkpoint) (see Note 10), for the development and commercialization of Jubilant’s novel
BET inhibitor program in the field of hematological malignancies.

F-25

Table of Contents

TG Therapeutics, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Under the terms of the agreement, we paid Checkpoint an up-front licensing fee of $1.0 million and will make additional payments
contingent  on  certain  preclinical,  clinical,  and  regulatory  milestones,  including  commercial  milestones  totaling  up  to  approximately  $177
million and a single-digit royalty on net sales. TG will also provide funding to support certain targeted research efforts at Jubilant.

TG-1701: BTK

In  January  2018,  we  entered  into  a  global  exclusive  license  agreement  with  Jiangsu  Hengrui  Medicine  Co.  (Hengrui),  to  acquire
worldwide  intellectual  property  rights,  excluding  Asia  but  including  Japan,  and  for  the  research,  development,  manufacturing,  and
commercialization of products containing or comprising of any of Hengrui’s Bruton’s Tyrosine Kinase inhibitors containing the compounds
of either TG-1701 (SHR1459 or EBI1459) or TG1702 (SHR1266 or EBI1266). Hengrui is eligible to receive milestone payments totaling
approximately $350 million upon and subject to the achievement of certain milestones. Various provisions allow for payments in conjunction
with the agreement to be made in cash or our common stock, while others limit the form of payment. In July 2019, we paid Hengrui the first
milestone  of  $0.1  million  in  our  common  stock  recorded  to  noncash  stock  expense  associated  with  in-licensing  agreements  in  our
consolidated  statement  of  operations.  In  July  2020,  we  paid  Hengrui  $2.0  million  as  part  of  a  milestone  in  accordance  with  the  license
agreement. Royalty payments in the low double digits are due on net sales of licensed products and revenue from sublicenses.

TG-1801: anti-CD47/anti-CD19

In June 2018, we entered into a Joint Venture and License Option Agreement with Novimmune SA (Novimmune) to collaborate on
the development and commercialization of Novimmune’s novel first-in-class anti-CD47/anti-CD19 bispecific antibody known as TG-1801
(previously  NI-1701).  The  companies  will  jointly  develop  the  product  on  a  worldwide  basis,  focusing  on  indications  in  the  area  of
hematologic B-cell malignancies. We serve as the primary responsible party for the development, manufacturing and commercialization of
the  product.  Milestone  payments  will  be  paid  based  on  early  clinical  development,  and  the  Company  will  be  responsible  for  the  costs  of
clinical development of the product through the end of the Phase 2 clinical trials, after which the Company and Novimmune will be jointly
responsible  for  all  development  and  commercialization  costs.  The  Company  and  Novimmune  will  each  maintain  an  exclusive  option,
exercisable at specific times during development, for the Company to license the rights to TG-1801, in which case Novimmune is eligible to
receive additional milestone payments totaling approximately $185 million as well as tiered royalties on net sales in the high single to low
double digits upon and subject to the achievement of certain milestones.

NOTE 10 – RELATED PARTY TRANSACTIONS

In July 2015, we entered into a Shared Services Agreement (the Shared Services Agreement) with FBIO to share the cost of certain
services such as facilities use, personnel costs and other overhead and administrative costs. This Shared Services Agreement requires us to
pay our respective share of services utilized. In connection with the Shared Services Agreement, we incurred expenses of approximately $0.9
million, $0.8 million, and $0.9 million for shared services for the years ended December 31, 2021, 2020 and 2019, respectively, primarily
related to shared personnel. Mr. Weiss, our Chairman and Chief Executive Officer, also serves as a director and Executive Vice Chairman,
Strategic Development of FBIO.

In  March  2015,  we  entered  into  the  Collaboration  Agreement  with  Checkpoint,  a  subsidiary  of  FBIO,  for  the  development  and
commercialization of anti-PD-L1 and anti-GITR antibody research programs in the field of hematological malignancies. In May 2016, as part
of a broader agreement with Jubilant, we entered into a sublicense agreement (JBET Agreement) with Checkpoint for the development and
commercialization of Jubilant’s novel BET inhibitor program in the field of hematological malignancies. Mr. Weiss also serves as Chairman
of the Board of Directors of Checkpoint.

Term Loan.

(a)

Advances.

20

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

(i)

Agent,  Lender  and  Borrower  acknowledge  that  prior  to  the  Closing  Date,

Borrower has drawn the Existing Term Loan.

(ii)

Subject to the terms and conditions of this Agreement, Lender will severally (and
not  jointly)  make  in  an  amount  not  to  exceed  its  respective  Term  Commitment,  and  Borrower
agrees to draw, a Term Loan Advance of Seventy Million Dollars ($70,000,000) on the Closing
Date (the “Tranche 1 Advance”), a portion of which shall be used by Borrower on the Closing
Date to repay the Existing Term Loan in full pursuant to Section 4.1(h). Subject to the terms and
conditions of this Agreement, beginning on the date Borrower achieves Performance Milestone I
and  continuing  through  December  31,  2022,  Borrower  may  request  and  Lender  shall  make  an
additional Term Loan Advance in a principal amount of Twenty Million Dollars ($20,000,000)
(the “Tranche 2 Advance”). Subject to the terms and conditions of this Agreement, beginning on
the date Borrower achieves Performance Milestone II and continuing through March 31, 2023,
Borrower may request and Lender shall make up to two additional Term Loan Advances in an
aggregate principal amount of up to Forty- Five Million Dollars ($45,000,000) with a minimum
initial increment of Twenty- Five Million Dollars ($25,000,000) (each a “Tranche 3 Advance”);
provided that the principal amount of the second Tranche 3 Advance (if any) shall equal Forty-
Five Million Dollars ($45,000,000) minus the principal amount of the initial Tranche 3 Advance.
Subject to the terms and conditions of this Agreement, and conditioned on approval by Lenders’
investment  committee  in  its  sole  discretion,  prior  to  the  Amortization  Date,  Borrower  may
request  additional  Term  Loan  Advances  in  an  aggregate  principal  amount  of  up  to  Sixty-Five
Million  Dollars  ($65,000,000),  in  minimum  increments  of  Five  Million  Dollars  ($5,000,000)
(each, a “Tranche 4 Advance”). The aggregate outstanding Term Loan Advances may be up to
but  shall  not  exceed  the  Maximum  Term  Loan  Amount  plus,  for  the  avoidance  of  doubt,  any
amount equal to the Term Loan PIK Interest added to principal pursuant to Section 2.2(c)(ii).

(b)

Advance  Request.  To  obtain  a  Term  Loan  Advance,  Borrower  shall  complete,  sign  and
deliver  an  Advance  Request  at  least  five  (5)  Business  Days  before  the  proposed  Advance  Date  (other
than the Tranche 1 Advance to be made on the Closing Date, for which Borrower shall complete, sign
and  deliver  an  Advance  Request  at  least  one  (1)  Business  Day  prior  to  the  Closing  Date)  to  Agent.
Lender shall fund the Term Loan Advance in the manner requested by the Advance Request provided
that  each  of  the  conditions  precedent  to  such  Term  Loan  Advance  is  satisfied  as  of  the  requested
Advance Date.

(c)

Interest.

(i)

Term Loan Cash Interest Rate. In addition to interest accrued pursuant to the Term
Loan PIK Interest Rate, the principal balance (including, for the avoidance of doubt, any amount
equal to the Term Loan PIK Interest added to

21

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be

principal pursuant to Section 2.2(c)(ii)) of each Term Loan Advance shall bear interest thereon
from such Advance Date (or from the date such amount equal to the Term Loan PIK Interest is
added to the principal) at the Term Loan Cash Interest Rate) based on a year consisting of 360
days, with interest computed daily based on the actual number of days elapsed. The Term Loan
Cash Interest Rate will float and change on the day the “prime rate” as reported in the Wall Street
Journal changes from time to time.

(ii)

Term Loan PIK Interest Rate. In addition to interest accrued pursuant to the Term
Loan  Cash  Interest  Rate,  the  principal  balance  of  each  Term  Loan  Advance  shall  bear  interest
thereon from such Advance Date at the Term Loan PIK Interest Rate based on a year consisting
of 360 days, with interest computed daily based on the actual number of days elapsed (the “Term
Loan  PIK  Interest”),  which  amount  shall  be  added  to  the  outstanding  principal  balance  and  so
capitalized  so  as  to  increase  the  outstanding  principal  balance  of  such  Term  Loan  Advance  on
each  payment  date  for  such  Advance  and  which  amount  shall  be  payable  when  the  principal
amount of the applicable Advance is payable in accordance with Section 2.2(d).

(d)

Payment.  Borrower  will  pay  interest  on  the  Term  Loan  Advance  on  the  first  (1st)
Business Day of each month, beginning on the first (1st) Business Day of the month after the Advance
Date  continuing  until  the  Amortization  Date.  Borrower  shall  repay  the  principal  balance  of  the  Term
Loan Advance that is outstanding as of the day immediately preceding the Amortization Date, in equal
monthly installments of principal and interest beginning on the Amortization Date and continuing on the
first (1st) Business Day of each month thereafter until the Secured Obligations are repaid; provided, that
if the Term Loan Cash Interest Rate is adjusted in accordance with its terms, or the Amortization Date or
the Term Loan Maturity Date is extended, the amount of each subsequent monthly installment shall be
recalculated so that the remaining payments shall be equal monthly installments of principal and interest
beginning on the first (1st) Business Day of the month following such recalculation and continuing on
the first (1st) Business Day of each month thereafter until the Secured Obligations are repaid in full. The
entire  remaining  principal  balance  of  the  Term  Loan  Advance  and  all  accrued  but  unpaid  interest
hereunder, shall be due and payable on the Term Loan Maturity Date. Borrower shall make all payments
under  this  Agreement  without  setoff,  recoupment  or  deduction  and  regardless  of  any  counterclaim  or
defense.  Lender  will  initiate  debit  entries  to  the  Borrower’s  account  as  authorized  on  the  ACH
Authorization (i) on each payment date of all periodic obligations payable to Lender with respect to the
Term  Loan  Advance  and  (ii)  out-of-pocket  legal  fees  and  costs  incurred  by  Agent  or  Lender  in
connection with Section 11.11 of this Agreement; provided that, with respect to clause (i) above, in the
event  that  Lender  or  Agent  informs  Borrower  that  Lender  will  not  initiate  a  debit  entry  to  such
Borrower’s  account  for  a  certain  amount  of  the  periodic  obligations  due  on  a  specific  payment  date,
Borrower shall pay to Lender such amount of periodic obligations in full in immediately available funds
on  such  payment  date;  provided,  further,  that,  with  respect  to  clause  (i)  above,  if  Lender  or  Agent
informs Borrower that

22

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

Lender  will  not  initiate  a  debit  entry  as  described  above  later  than  the  date  that  is  three  (3)  Business
Days prior to such payment date, Borrower shall pay to Lender such amount of periodic obligations in
full in immediately available funds on the date that is three (3) Business Days after the date on which
Lender or Agent notifies Borrower thereof; provided, further, that, with respect to clause (ii) above, in
the  event  that  Lender  or  Agent  informs  Borrower  that  Lender  will  not  initiate  a  debit  entry  to  a
Borrower’s  account  for  specified  out-of-pocket  legal  fees  and  costs  incurred  by  Agent  or  Lender,
Borrower  shall  pay  to  Lender  such  amount  in  full  in  immediately  available  funds  within  three  (3)
Business Days.

2.3 Maximum  Interest.  Notwithstanding  any  provision  in  this  Agreement  or  any  other  Loan
Document, it is the parties’ intent not to contract for, charge or receive interest at a rate that is greater
than the maximum rate permissible by law that a court of competent jurisdiction shall deem applicable
hereto  (which  under  the  laws  of  the  State  of  California  shall  be  deemed  to  be  the  laws  relating  to
permissible  rates  of  interest  on  commercial  loans)  (the  “Maximum  Rate”).  If  a  court  of  competent
jurisdiction  shall  finally  determine  that  Borrower  has  actually  paid  to  Lender  an  amount  of  interest  in
excess  of  the  amount  that  would  have  been  payable  if  all  of  the  Secured  Obligations  had  at  all  times
borne interest at the Maximum Rate, then such excess interest actually paid by Borrower shall be applied
as  follows:  first,  to  the  payment  of  the  Secured  Obligations  consisting  of  the  outstanding  principal;
second,  after  all  principal  is  repaid,  to  the  payment  of  Lender’s  accrued  interest,  costs,  expenses,
professional fees and any other Secured Obligations; and third, after all Secured Obligations are repaid,
the excess (if any) shall be refunded to Borrower.

2.4

Default Interest. In the event any payment is not paid on the scheduled payment date, an
amount equal to four percent (4%) of the past due amount shall be payable on demand. In addition, upon
the  occurrence  and  during  the  continuation  of  an  Event  of  Default  hereunder,  all  Secured  Obligations,
including principal, interest, compounded interest, and professional fees, shall bear interest at a rate per
annum equal to the rate set forth in Section 2.2(c), plus four percent (4%) per annum. In the event any
interest  is  not  paid  when  due  hereunder,  delinquent  interest  shall  be  added  to  principal  and  shall  bear
interest on interest, compounded at the rate set forth in Section 2.2(c) or Section 2.4, as applicable.

2.5

Prepayment. At its option upon written notice to Agent, Borrower may prepay all or any
portion  of  the  outstanding  Advances  by  paying  the  entire  principal  balance  (or  portion  thereof,  which
portion  shall  include  a  proportionate  amount  of  initial  principal  of  the  applicable  Advances  being
prepaid, and principal attributable to Term Loan PIK Interest added to the outstanding principal balance
of such Advances pursuant to Section 2.2(c)(ii)), all accrued and unpaid interest thereon, together with a
prepayment  charge  equal  to  the  following  percentage  of  the  Advance  amount  being  prepaid:  (a)  with
respect  to  the  initial  principal  amount  of  each  Advance  being  prepaid,  if  such  Advance  amounts  are
prepaid  on  or  prior  to  the  first  (1st)  anniversary  of  the  Closing  Date,  2.00%;  after  the  first  (1st)
anniversary but on or prior to the second (2nd) anniversary of the Closing

23

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

Date,  1.50%;  after  the  second  (2nd)  anniversary  but  on  or  prior  to  the  third  (3rd)  anniversary  of  the
Closing  Date,  1.00%;  and  thereafter,  0.00%  and  (b)  with  respect  to  the  principal  attributable  to  Term
Loan PIK Interest added to the outstanding principal balance of the Advances pursuant to Section 2.2(c)
(ii), if such Advance amounts are prepaid on or prior to the thirty (30) month anniversary of the Closing
Date,  1.00%;  and  thereafter,  0.00%  (clauses  (a)  and  (b),  collectively,  the  “Prepayment  Charge”).
Borrower agrees that the Prepayment Charge is a reasonable calculation of Lender’s lost profits in view
of the difficulties and impracticality of determining actual damages resulting from an early repayment of
the Advances. Borrower shall prepay the outstanding amount of all principal and accrued interest through
the  prepayment  date  and  the  Prepayment  Charge  upon  the  occurrence  of  a  Change  in  Control.
Notwithstanding the foregoing, no Prepayment Charge will be required to be paid in connection with any
prepayment if such prepayment is made in connection with a refinancing of the Advances with Agent and
Lender  (such  refinancing  to  be  made  in  Agent  and  Lenders’  sole  and  absolute  discretion)  prior  to  the
Term  Loan  Maturity  Date.  Any  amounts  paid  under  this  Section  shall  be  applied  by  Agent  to  the  then
unpaid amount of any Secured Obligations (including principal and interest) in such order and priority as
Agent may choose in its sole discretion.

2.6

End of Term Charge.

(a)

On  the  earliest  to  occur  of  (i)  March  1,  2022,  (ii)  the  date  that  Borrower  prepays  the
outstanding  Secured  Obligations  (other  than  any  inchoate  indemnity  obligations  and  any  other
obligations which, by their terms, are to survive the termination of this Agreement) in full, or (iii) the
date that the Secured Obligations become due and payable, Borrower shall pay Existing Lender a charge
equal  to  Nine  Hundred  Seventy-  Five  Thousand  Dollars  ($975,000)  in  respect  of  the  Existing  Term
Loan, which payment will, for the avoidance of doubt, satisfy the “End of Term Charge” referred to in
the  Existing  Loan  Agreement.  Notwithstanding  the  required  payment  date  of  such  charge,  it  shall  be
deemed earned by Existing Lender as of the Prior Closing Date (the “Existing End of Term Charge”).

(b)

On the earliest to occur of (i) the Term Loan Maturity Date, (ii) the date that Borrower
prepays  the  outstanding  Secured  Obligations  (other  than  any  inchoate  indemnity  obligations  and  any
other obligations which, by their terms, are to survive the termination of this Agreement) in full, or (iii)
the  date  that  the  Secured  Obligations  become  due  and  payable,  Borrower  shall  pay  Lender  a  charge
equal  to  5.95%  of  the  aggregate  principal  amount  of  the  Term  Loan  Advances.  Notwithstanding  the
required payment date of such charge, the applicable pro rata portion of the End of Term Charge shall be
deemed earned by Lender as of the applicable Advance Date.

2.7

Notes.  If  so  requested  by  Lender  by  written  notice  to  Borrower,  then  Borrower  shall
execute and deliver to Lender (and/or, if applicable and if so specified in such notice, to any Person who
is an assignee of Lender pursuant to Section 11.13) (promptly after the Borrower’s receipt of such notice)
a Note or Notes to evidence Lender’s Loans.

24

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

2.8

Pro Rata Treatment. Each payment (including prepayment) on account of any fee and any
reduction of the Term Loans shall be made pro rata according to the Term Commitments of the relevant
Lender.

2.9

Taxes.

(a)

Defined Terms. For purposes of this Section, the term “applicable law” includes FATCA.

(b)

Payments Free of Taxes. Any and all payments by or on account of any obligation of the
Borrower  under  any  Loan  Document  shall  be  made  without  deduction  or  withholding  for  any  Taxes,
except as required by applicable law. If any applicable law (as determined in the good faith discretion of
an  applicable  Withholding  Agent)  requires  the  deduction  or  withholding  of  any  Tax  from  any  such
payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such
deduction  or  withholding  and  shall  timely  pay  the  full  amount  deducted  or  withheld  to  the  relevant
governmental authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then
the  sum  payable  by  the  Borrower  shall  be  increased  as  necessary  so  that  after  such  deduction  or
withholding has been made (including such deductions and withholdings applicable to additional sums
payable under this Section) the applicable Recipient receives an amount equal to the sum it would have
received had no such deduction or withholding of Indemnified Taxes been made.

(c)

Payment  of  Other  Taxes  by  Borrower.  The  Borrower  shall  timely  pay  to  the  relevant
governmental  authority  in  accordance  with  applicable  law,  or  at  the  option  of  the  Agent  timely
reimburse it for the payment of, any Other Taxes.

(d)

Indemnification  by  Borrower.  The  Borrower  shall  indemnify  each  Recipient,  within  10
days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes
imposed or asserted 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 to such Recipient and any reasonable
expenses  arising  therefrom  or  with  respect  thereto,  whether  or  not  such  Indemnified  Taxes  were
correctly or legally imposed or asserted by the relevant governmental authority. A certificate as to the
amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Agent),
or by the Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e)

Indemnification by the Lenders. Each Lender shall severally indemnify the Agent, within
10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the
extent that the Borrower has not already indemnified the Agent for such Indemnified Taxes and without
limiting  the  obligation  of  the  Borrower  to  do  so),  and  (ii)  any  Excluded  Taxes  attributable  to  such
Lender, in each case, that are payable or paid by the Agent in connection with any Loan Document, and
any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were

25

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be

correctly or legally imposed or asserted by the relevant governmental authority. A certificate as to the
amount  of  such  payment  or  liability  delivered  to  any  Lender  by  the  Agent  shall  be  conclusive  absent
manifest error. Each Lender hereby authorizes the Agent to set off and apply any and all amounts at any
time owing to such Lender under any Loan Document or otherwise payable by the Agent to the Lender
from any other source against any amount due to the Agent under this paragraph (e).

(f)

Evidence  of  Payments.  As  soon  as  practicable  after  any  payment  of  Taxes  by  the
Borrower to a governmental authority pursuant to this Section, the Borrower shall deliver to the Agent
the  original  or  a  certified  copy  of  a  receipt  issued  by  such  governmental  authority  evidencing  such
payment,  a  copy  of  the  return  reporting  such  payment  or  other  evidence  of  such  payment  reasonably
satisfactory to the Agent.

(g)

Status of Lenders.

(i)

Any Lender that is entitled to an exemption from or reduction of withholding Tax
with respect to payments made under any Loan Document shall deliver to the Borrower and the
Agent,  at  the  time  or  times  reasonably  requested  by  the  Borrower  or  the  Agent,  such  properly
completed  and  executed  documentation  reasonably  requested  by  the  Borrower  or  the  Agent  as
will permit such payments to be made without withholding or at a reduced rate of withholding.
In addition, any Lender, if reasonably requested by the Borrower or the Agent, shall deliver such
other  documentation  prescribed  by  applicable  law  or  reasonably  requested  by  the  Borrower  or
the Agent as will enable the Borrower or the Agent to determine whether or not such Lender is
subject to backup withholding or information reporting requirements. Notwithstanding anything
to the contrary in the preceding two sentences, the completion, execution and submission of such
documentation (other than such documentation set forth in paragraphs (g)(ii)(1), (ii)(2) and (iv)
of  this  Section)  shall  not  be  required  if  in  the  Lender’s  reasonable  judgment  such  completion,
execution  or  submission  would  subject  such  Lender  to  any  material  unreimbursed  cost  or
expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing, in the event that the Borrower is

a U.S. Person,

1.

2.

any Lender that is a U.S. Person shall deliver to the Borrower and the Agent on or

Lender is a partnership and one or more direct or indirect partners of such Foreign
Lender  are  claiming  the  portfolio  interest  exemption,  such  Foreign  Lender  may
provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit K-
4 on behalf of each such direct and indirect partner;

(iii)

any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the

Borrower and the Agent (in such number of copies as shall be

requested by the recipient) on or about the date on which such Foreign Lender becomes a Lender
under  this  Agreement  (and  from  time  to  time  thereafter  upon  the  reasonable  request  of  the
Borrower  or  the  Agent),  executed  copies  of  any  other  form  prescribed  by  applicable  law  as  a
basis  for  claiming  exemption  from  or  a  reduction  in  U.S.  federal  withholding  Tax,  duly
completed, together with such supplementary documentation as may be prescribed by applicable
law to permit the Borrower or the Agent to determine the withholding or deduction required to
be made; and

(iv)

if  a  payment  made  to  a  Lender  under  any  Loan  Document  would  be  subject  to
U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the
applicable  reporting  requirements  of  FATCA  (including  those  contained  in  Section  1471(b)  or
1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Agent at
the  time  or  times  prescribed  by  law  and  at  such  time  or  times  reasonably  requested  by  the
Borrower or the Agent such documentation prescribed by applicable law (including as prescribed
by  Section  1471(b)(3)(C)(i)  of  the  Code)  and  such  additional  documentation  reasonably
requested by the Borrower or the Agent as may be necessary for the Borrower and the Agent to
comply  with  their  obligations  under  FATCA  and  to  determine  that  such  Lender  has  complied
with such Lender’s obligations under FATCA or to determine the amount, if any, to deduct and
withhold from such payment. Solely for purposes of this clause (iv), “FATCA” shall include any
amendments made to FATCA after the date of this Agreement.

(h)

Each  Lender  agrees  that  if  any  form  or  certification  it  previously  delivered  expires  or
becomes  obsolete  or  inaccurate  in  any  respect,  it  shall  update  such  form  or  certification  or  promptly
notify the Borrower and the Agent in writing of its legal inability to do so.

(i)

Treatment of Certain Refunds. 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
paragraph  (i)  (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  paragraph  (i),  in  no  event  will  the
indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (i)
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

28

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be

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 paragraph 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.

(j)

Survival.  Each  party’s  obligations  under  this  Section  shall  survive  the  resignation  or
replacement  of  the  Agent  or  any  assignment  of  rights  by,  or  the  replacement  of,  a  Lender,  the
termination  of  the  Term  Commitment  and  the  repayment,  satisfaction  or  discharge  of  all  obligations
under any Loan Document.

2.10 Borrower agrees that the Existing End of Term Charge, any Prepayment Charge and any
End  of  Term  Charge  (collectively,  the  “Prepayment  and  End  of  Term  Charges”)  payable  shall  be
presumed to be the liquidated damages sustained by each Lender as the result of the early termination,
and Borrower agrees that it is reasonable under the circumstances existing as of the Closing Date (and,
with respect to the Existing End of Term Charge as of the Prior Closing Date). The Prepayment and End
of Term Charges shall also be payable in the event the Secured 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. Borrower expressly waives (to the fullest extent it may lawfully do
so) the provisions of any present or future statute or law that prohibits or may prohibit the collection of
the foregoing Prepayment and End of Term Charges in connection with any such acceleration. Borrower
agrees (to the fullest extent that each may lawfully do so): (a) each of the Prepayment and End of Term
Charges is reasonable and is the product of an arm’s length transaction between sophisticated business
people,  ably  represented  by  counsel;  (b)  each  of  the  Prepayment  and  End  of  Term  Charges  shall  be
payable notwithstanding the then prevailing market rates at the time payment is made; (c) there has been
a course of conduct between the Lenders and Borrower giving specific consideration in this transaction
for such agreement to pay each of the Prepayment and End of Term Charges as a charge (and not interest)
in the event of prepayment or acceleration; (d) Borrower shall be estopped from claiming differently than
as agreed to in this paragraph.   Borrower expressly acknowledges that their agreement to pay each of the
Prepayment Charge and the End of Term Charge to the Lenders as herein described was on the Closing
Date (and, with respect to the Existing End of Term Charge as of the Prior Closing Date), and continues
to  be, a material inducement to the Lenders to provide the Term Loans.

SECTION 3. SECURITY INTEREST

3.1

As  security  for  the  prompt  and  complete  payment  when  due  (whether  on  the  payment
dates  or  otherwise)  of  all  the  Secured  Obligations,  Borrower  grants,  and  reaffirms  the  grant  provided
under the Existing Loan Agreement and all Existing Loan Documents, to Agent a security interest in all
of  Borrower’s  right,  title,  and  interest  in,  to  and  under  all  of  Borrower’s  personal  property  and  other
assets (other than any Intellectual Property) including without limitation the following (except as set forth
herein) whether now owned

29

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

or  hereafter  acquired  (collectively,  the  “Collateral”):  (a)  Receivables;  (b)  Equipment;  (c)  Fixtures;  (d)
General Intangibles (other than Intellectual Property); (e) Inventory; (f) Investment Property; (g) Deposit
Accounts;  (h)  Cash;  (i)  Goods;  and  all  other  tangible  and  intangible  personal  property  of  Borrower
whether  now  or  hereafter  owned  or  existing,  leased,  consigned  by  or  to,  or  acquired  by,  Borrower  and
wherever located, and any of Borrower’s property in the possession or under the control of Agent; and, to
the  extent  not  otherwise  included,  all  Proceeds  of  each  of  the  foregoing  and  all  accessions  to,
substitutions  and  replacements  for,  and  rents,  profits  and  products  of  each  of  the  foregoing;  provided,
however, that the Collateral shall include all Accounts and General Intangibles that consist of rights to
payment  and  proceeds  from  the  sale,  licensing  or  disposition  of  all  or  any  part,  or  rights  in,  the
Intellectual  Property  (the  “Rights  to  Payment”).  Notwithstanding  the  foregoing,  if  a  judicial  authority
(including a U.S. Bankruptcy Court) holds that a security interest in the underlying Intellectual Property
is necessary to have a security interest in the Rights to Payment, then the Collateral shall automatically,
and effective as of the date of this Agreement, include the Intellectual Property to the extent necessary to
permit perfection of Agent’s security interest in the Rights to Payment.

3.2

Notwithstanding the broad grant of the security interest set forth in Section 3.1 above, the
Collateral shall not include (a) licenses or other contracts, which by their terms require the consent of the
licensor thereof or another party for a grant of a security interest therein or the assignment thereof or in
any  assets  subject  thereto  (but  only  to  the  extent  such  prohibition  on  transfer  is  enforceable  under
applicable  law,  including,  without  limitation,  Sections  9406,  9407  and  9408  of  the  UCC),  (b)  any
property  and  assets  the  pledge  of  which  would  require  governmental  consent,  approval,  license  or
authorization  or  is  prohibited  or  restricted  by  applicable  law  (after  giving  effect  to  the  applicable  anti-
assignment  provisions  of  the  UCC  or  other  applicable  law),  (c)  Equipment  or  other  assets  otherwise
constituting  Collateral  owned  by  Borrower  on  the  date  hereof  or  hereafter  acquired  that  is  subject  to  a
Lien securing purchase money Indebtedness or capital lease obligations permitted to be incurred pursuant
to the provisions of this Agreement if the contract or other agreement in which such Lien is granted (or
the documentation providing for such purchase money Indebtedness or capital lease obligations) validly
prohibits the creation of any other Lien on such Equipment or such other asset, (d) Excluded Accounts,
or  (e)  more  than  65%  of  the  presently  existing  and  hereafter  arising  issued  and  outstanding  shares  of
capital  stock  owned  by  Borrower  of  any  Excluded  Foreign  Subsidiary  which  shares  entitle  the  holder
thereof  to  vote  for  directors  or  any  other  matter;  provided  that  with  respect  to  clauses  (a),  (b)  and  (c),
upon  termination  of  such  prohibition,  such  interest  shall  immediately  become  Collateral  without  any
action by Borrower, Agent or Lender.

SECTION 4. CONDITIONS PRECEDENT TO LOAN

The obligations of Lender to make the Loan hereunder are subject to the satisfaction by Borrower of the

following conditions:

earlier date.

SECTION 5. REPRESENTATIONS AND WARRANTIES OF BORROWER

Borrower represents and warrants that:

5.1

Corporate Status. Each Borrower is a corporation duly organized, legally existing and in
good standing under the laws of the State of Delaware, and is duly qualified as a foreign corporation in
all jurisdictions in which the nature of its business or location of its properties require such qualifications
and  where  the  failure  to  be  qualified  could  reasonably  be  expected  to  have  a  Material  Adverse  Effect.
Each Borrower’s present name, former names (if any), locations, place of formation, Tax identification
number, organizational identification number and other information are correctly set forth in

32

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

Exhibit C, as may be updated by such Borrower in a written notice (including any Compliance
Certificate) provided to Agent after the Closing Date.

5.2

Collateral.  Each  Borrower  owns  the  applicable  Collateral  and  the  Intellectual  Property,
free  of  all  Liens,  except  for  Permitted  Liens.  Each  Borrower  has  the  power  and  authority  to  grant  to
Agent a Lien in the Collateral as security for the Secured Obligations.

5.3

Consents. Each Borrower’s execution, delivery and performance of this Agreement and all
other  Loan  Documents,  and  Parent’s  execution  of  the  Warrant,  (i)  have  been  duly  authorized  by  all
necessary  corporate  action  of  such  Borrower  or  the  Parent,  as  applicable,  (ii)  will  not  result  in  the
creation or imposition of any Lien upon the Collateral, other than Permitted Liens and the Liens created
by  this  Agreement  and  the  other  Loan  Documents,  (iii)  do  not  (x)  violate  any  provisions  of  such
Borrower’s Certificate or Articles of Incorporation (as applicable) and bylaws, or (y) any material law,
material  regulation,  material  order,  material  injunction,  material  judgment,  material  decree  or  material
writ to which such Borrower is subject and (iv) except as described on Schedule 5.3, do not violate any
material contract or material agreement or require the material consent or material approval of any other

Documents and the Warrant are duly authorized to do so.

5.4 Material Adverse Effect. No event that has had or could reasonably be expected to have a
Material  Adverse  Effect  has  occurred  and  is  continuing.  No  Borrower  is  aware  of  any  event  likely  to
occur that is reasonably expected to result in a Material Adverse Effect.

5.5

Actions  Before  Governmental  Authorities.  There  are  no  actions,  suits  or  proceedings  at
law  or  in  equity  or  by  or  before  any  governmental  authority  now  pending  or,  to  the  knowledge  of  any
Borrower,  threatened  against  or  affecting  any  Borrower  or  its  property,  that  is  reasonably  expected  to
result in a Material Adverse Effect.

5.6

Laws.  No  Borrower  nor  any  of  its  Subsidiaries  is  in  violation  of  any  law,  rule  or
regulation,  or  in  default  with  respect  to  any  judgment,  writ,  injunction  or  decree  of  any  governmental
authority, where such violation or default is reasonably expected to result in a Material Adverse Effect.
To  the  knowledge  of  Borrower,  no  Borrower  is  in  default  in  any  manner  under  any  provision  of  any
agreement or instrument evidencing material Indebtedness, or any other material agreement to which it is
a party or by which it is bound.

No Borrower nor any of its Subsidiaries is an “investment company” or a company “controlled”
by an “investment company” under the Investment Company Act of 1940, as amended. No Borrower nor
any of its Subsidiaries is engaged as one of its important activities in extending credit for margin stock

its Subsidiaries has

33

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

complied in all material respects with the Federal Fair Labor Standards Act. No Borrower nor any of its
Subsidiaries is a “holding company” or an “affiliate” of a “holding company” or a “subsidiary company”
of a “holding company” as each term is defined and used in the Public Utility Holding Company Act of
2005. No Borrower’s nor any of its Subsidiaries’ properties or assets has been used by any Borrower or
such Subsidiary or, to any Borrower’s knowledge, by previous Persons, in disposing, producing, storing,
treating, or transporting any hazardous substance other than in material compliance with applicable laws.
Each  Borrower  and  each  of  its  Subsidiaries  has  obtained  all  consents,  approvals  and  authorizations  of,
made  all  declarations  or  filings  with,  and  given  all  notices  to,  all  Governmental  Authorities  that  are
necessary to continue their respective businesses as currently conducted, except as would not reasonably
be expected to have a Material Adverse Effect.

No  Borrower,  nor  any  of  its  Subsidiaries,  nor,  to  the  knowledge  of  any  Borrower,  any  of  such
Borrower’s or its Subsidiaries’ controlled Affiliates or any of their respective agents acting or benefiting
in any capacity in connection with the transactions contemplated by this Agreement is (i) in violation of
any Anti-Terrorism Law, (ii) engaging in or conspiring to engage in any transaction that evades or avoids,
or has the purpose of evading or avoiding or attempts to violate, any of the prohibitions set forth in any
Anti-Terrorism  Law,  or  (iii)  is  a  Blocked  Person.  None  of  any  Borrower,  or  its  Subsidiaries,  or  to  the
knowledge of any Borrower, any of its controlled Affiliates or agents, acting or benefiting in any capacity
in connection with the transactions contemplated by this Agreement, (x) conducts any business or engages
in making or receiving any contribution of funds, goods or services to or for the benefit of any Blocked
Person,  or  (y)  deals  in,  or  otherwise  engages  in  any  transaction  relating  to,  any  property  or  interest  in
property  blocked  pursuant  to  Executive  Order  No.  13224,  any  similar  executive  order  or  other  Anti-
Terrorism Law. None of the funds to be provided under this Agreement will be used, directly or, to the
knowledge  of  any  Borrower,  indirectly,  (a)  for  any  activities  in  violation  of  any  applicable  anti-money
laundering, economic sanctions and anti-bribery laws and regulations laws and regulations or (b) for any
payment to any governmental official or employee, political party, official of a political party, candidate
for political office, or anyone else acting in an official capacity, in order to obtain, retain or direct business
or obtain any improper advantage, in violation of the United States Foreign Corrupt Practices Act of 1977,
as amended.

5.7

Information  Correct  and  Current.  No  information,  report,  Advance  Request,  financial
statement, exhibit or schedule furnished, by or on behalf of Borrower to Agent in connection with any
Loan Document or included therein or delivered pursuant thereto, when taken as a whole, contained or
contains  or  will  contain  any  material  misstatement  of  fact  or,  when  taken  together  with  all  other  such
information or documents, omitted, omits or will omit to state any material fact necessary to make the
statements  therein,  in  the  light  of  the  circumstances  under  which  they  were,  are  or  will  be  made,  not
materially misleading  at  the  time  such  statement  was  made  or  deemed  made.  Additionally, any and all
financial  or  business  projections  provided  by  Borrower  to  Agent,  whether  prior  to  or  after  the  Closing
Date, shall be (i) provided in good faith and based on the most

34

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

current data and information available to Borrower, and (ii) the most current of such projections provided
to Borrower’s board of directors; it being understood by the Agent and the Lender that such projections
as  to  future  events  (i)  are  not  to  be  viewed  as  facts,  (ii)(A)  are  subject  to  significant  uncertainties  and
contingencies, many of which are beyond the control of Borrower, (B) no assurance is given by Borrower
that  the  results  forecast  in  any  such  projections  will  be  realized  and  (C)  the  actual  results  during  the
period or periods covered by any such projections may differ from the forecast results set forth in such
projections and such differences may be material and (iii) are not a guarantee of performance.

5.8

Tax Matters. Except as described on Schedule 5.8 and except those Taxes being contested
in  good  faith  with  adequate  reserves  under  GAAP,  (a)  Borrower  and  its  Subsidiaries  have  filed  all
material  federal,  state  and  local  Tax  returns  that  they  are  required  to  file,  (b)  Borrower  and  its
Subsidiaries have duly paid or fully reserved for all Taxes or installments thereof (including any interest
or penalties) prior to becoming delinquent, which have or may become due pursuant to such returns, and
(c) Borrower and its Subsidiaries have paid or fully reserved for any material Tax assessment received by
Borrower  or  its  Subsidiaries  for  the  three  (3)  years  preceding  the  Closing  Date,  if  any  (including  any
Taxes being contested in good faith and by appropriate proceedings).

5.9

Intellectual  Property  Claims.  Each  Borrower  is  the  sole  owner  of,  or  otherwise  has  the
right  to  use,  the  Intellectual  Property  material  to  such  Borrower’s  business.  Except  as  described  on
Schedule 5.9, (i) each of the material Copyrights, Trademarks and Patents is valid and enforceable, (ii) no
material  part  of  the  Intellectual  Property  has  been  judged  invalid  or  unenforceable  by  a  court  of
competent jurisdiction, in whole or in part, and (iii) no claim has been made to any Borrower that any
material part of the Intellectual Property violates the rights of any third party. Exhibit D is a true, correct
and complete list of each Borrower’s Patents, registered Trademarks, registered Copyrights, and material
agreements  under  which  such  Borrower  licenses  Intellectual  Property  from  third  parties  (other  than
shrink-wrap  software  licenses),  together  with  application  or  registration  numbers,  as  applicable,  owned
by  such  Borrower  or  any  Subsidiary,  in  each  case  as  of  the  Closing  Date.  No  Borrower  is  in  material
breach of, nor has any Borrower failed to perform any material obligations under, any of the foregoing
contracts, licenses or agreements and, to such Borrower’s knowledge, no third party to any such contract,
license  or  agreement  is  in  material  breach  thereof  or  has  failed  to  perform  any  material  obligations
thereunder.

5.10

Intellectual  Property.  Except  as  described  on  Schedule  5.10,  each  Borrower  has  all
material rights with respect to Intellectual Property necessary or material to the operation or conduct of
such  Borrower’s  business  as  currently  conducted  and  proposed  to  be  conducted  by  such  Borrower.
Without limiting the generality of the foregoing, and in the case of Licenses, except for restrictions that
are unenforceable under Division 9 of the UCC, each Borrower has the right, to the extent required to
operate such Borrower’s business, to freely transfer, license or assign Intellectual Property necessary or
material in the operation or conduct of such Borrower’s business as currently conducted

35

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

and proposed to be conducted by such Borrower, without condition, restriction or payment of any kind
(other than license payments in the ordinary course of business) to any third party, and such Borrower
owns or has the right to use, pursuant to valid licenses, all software development tools, library functions,
compilers and all other third-party software and other items that are material to such Borrower’s business
and  used  in  the  design,  development,  promotion,  sale,  license,  manufacture,  import,  export,  use  or
distribution  of  Borrower  Products  except  customary  covenants  in  inbound  license  agreements  and
equipment leases where such Borrower is the licensee or lessee.   No Borrower is a party to, nor are they
bound by, any Restricted License.

5.11 Borrower Products. Except as described on Schedule 5.11, no Intellectual Property owned
by any Borrower or Borrower Product has been or is subject to any actual or, to the knowledge of such
Borrower,  threatened  litigation,  proceeding  (including  any  proceeding  in  the  United  States  Patent  and
Trademark Office or any corresponding foreign office or agency) or outstanding decree, order, judgment,
settlement agreement or stipulation that restricts in any manner such Borrower’s use, transfer or licensing
thereof or that may affect the validity, use or enforceability thereof. There is no decree, order, judgment,
agreement, stipulation, arbitral award or other provision entered into in connection with any litigation or
proceeding that obligates any Borrower to grant licenses or ownership interest in any future Intellectual
Property related to the operation or conduct of the business of such Borrower or Borrower Products. No
Borrower has received any written notice or claim, or, to the knowledge of such Borrower, oral notice or
claim,  challenging  or  questioning  such  Borrower’s  ownership  in  any  Intellectual  Property  (or  written
notice of any claim challenging or questioning the ownership in any licensed Intellectual Property of the
owner  thereof)  or  suggesting  that  any  third  party  has  any  claim  of  legal  or  beneficial  ownership  with
respect thereto nor, to such Borrower’s knowledge is there a reasonable basis for any such claim. To the
knowledge of each Borrower, no Borrower’s use of its Intellectual Property nor the production and sale
of the Borrower’s Borrower Products infringes the intellectual property or other rights of others. Other
than as publically disclosed by Borrower in its 8-K filed with the SEC on November 30, 2021 regarding a
planned Oncologic Drugs Advisory Committee meeting, there have been no recalls, field notifications,
field corrections, market withdrawals, warnings, “dear doctor” letters, investigator notices, safety alerts
or other notice of action relating to an alleged lack of safety, efficacy, or regulatory compliance of any
Borrower  Products  (“Safety  Notices”)  and  to  the  knowledge  of  any  Borrower,  there  are  no  facts  that
would be reasonably likely to result in (i) a Safety Notice with respect to any Borrower Products, (ii)a
change in labeling of any Borrower Products or (iii) a termination or suspension of marketing or testing
of any Borrower Products.

5.12

provided to Agent after the Closing Date, is a true, correct and complete list of (a) all banks and other
financial  institutions  at  which  Borrower  or  any  Subsidiary  maintains  Deposit  Accounts  and  (b)  all

which the account is held, a description of the purpose of the account, and the complete account number

5.13

employee, officer or director of such Borrower nor has any Borrower guaranteed, as of the Closing Date,
the payment of any loan made to an employee, officer or director of such Borrower by a third party.

5.14 Capitalization  and  Subsidiaries.  Borrower’s  capitalization  as  of  the  Closing  Date  is  set
forth on Schedule 5.14 annexed hereto. Borrower does not own any stock, partnership interest or other
securities of any Person, except for Permitted Investments. Attached as Schedule 1, as may be updated by
Borrower in a written notice provided after the Closing Date, is a true, correct and complete list of each
Subsidiary.

5.15 Ariston Notes.

(a)

Neither the Borrower nor any Subsidiary (other than Ariston) has any obligations, in each
case under the Ariston Notes, to commercialize or sell any AST-726 or AST-914 program candidates or
otherwise to generate any Product Proceeds in respect thereof.

(b)

The  holders  of  the  Ariston  Notes  have  no  recourse,  now  or  after  the  filing  of  any
Insolvency  Proceeding  or  other  insolvency  event  (including  under  Section  7  of  the  Ariston  Notes  or
otherwise, including without limitation under applicable law), to any Borrower or its Subsidiaries (other
than Ariston) other than with respect to equity conversion rights specified in the Ariston Notes.

(c)

Ariston has been a dormant subsidiary for the last five (5) years and holds no assets and

liabilities other than legacy intercompany receivables and payables and the Ariston Notes.

SECTION 6. INSURANCE; INDEMNIFICATION

6.1

Coverage. Borrower shall cause to be carried and maintained commercial general liability
insurance,  on  an  occurrence  form,  against  risks  customarily  insured  against  in  Borrower’s  line  of
business. Such risks shall include the risks of bodily injury, including death, property damage, personal
injury, advertising injury, and contractual liability per the terms of the indemnification agreement found
in Section 6.3. Borrower must maintain a minimum of Two Million Dollars ($2,000,000) of commercial
general liability insurance for each occurrence. Borrower has and agrees to maintain a minimum of Two
Million Dollars ($2,000,000) of directors’ and officers’ insurance for each occurrence and Five Million
Dollars  ($5,000,000)  in  the  aggregate.  So  long  as  there  are  any  Secured  Obligations  outstanding,
Borrower shall also cause to be carried and maintained insurance upon the Collateral, insuring against all
risks of physical loss or damage howsoever caused, in an amount not less than the full replacement cost
of the

37

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

Collateral, provided that such insurance may be subject to standard exceptions and deductibles.

6.2

Certificates.  Borrower  shall  deliver  to  Agent  certificates  of  insurance  that  evidence
Borrower’s compliance with its insurance obligations in Section 6.1 and the obligations contained in this
Section  6.2.  Borrower’s  insurance  certificate  shall  state  Agent  (shown  as  “Hercules  Capital,  Inc.,  as
Administrative and Collateral Agent, and its permitted assigns”) is an additional insured for commercial
general  liability,  a  lender  loss  payee  for  all  risk  property  damage  insurance,  subject  to  the  insurer’s
approval, and a lender loss payee for property insurance and additional insured for liability insurance for
any  future  insurance  that  Borrower  may  acquire  from  such  insurer.  Attached  to  the  certificates  of
insurance will be additional insured endorsements for liability and lender’s loss payable endorsements for
all risk property damage insurance. All certificates of insurance will provide for a minimum of thirty (30)
days  advance  written  notice  to  Agent  of  cancellation  (other  than  cancellation  for  non-payment  of
premiums,  for  which  ten  (10)  days’  advance  written  notice  shall  be  sufficient)  or  any  other  change
adverse to Agent’s interests. Any failure of Agent to scrutinize such insurance certificates for compliance
is  not  a  waiver  of  any  of  Agent’s  rights,  all  of  which  are  reserved.  Borrower  shall  provide  Agent  with
copies of each insurance policy, and upon entering or amending any insurance policy required hereunder,
Borrower shall provide Agent with copies of such policies and shall promptly deliver to Agent updated
insurance certificates with respect to such policies.

6.3

Indemnity.      Borrower  agrees  to  indemnify  and  hold  Agent,  Lender  and  their  officers,
directors, employees, agents, in-house attorneys, representatives and shareholders (each, an “Indemnified
Person”)  harmless  from  and  against  any  and  all  claims,  costs,  expenses,  damages  and  liabilities
(including such claims, costs, expenses, damages and liabilities based on liability in tort, including strict
liability in tort), including reasonable attorneys’ fees and disbursements and other costs of investigation
or defense (including those incurred upon any appeal) (collectively, “Liabilities”), that may be instituted
or asserted against or incurred by such Indemnified Person as the result of credit having been extended,
suspended or terminated under this Agreement and the other Loan Documents or the administration of
such  credit,  or  in  connection  with  or  arising  out  of  the  transactions  contemplated  hereunder  and
thereunder, or any actions or failures to act in connection therewith, or arising out of the disposition or
utilization of the Collateral; provided that, no Indemnified Person will be indemnified for its (or any of its
Related  Parties)  willful  misconduct,  bad  faith  or  gross  negligence  (to  the  extent  determined  in  a  final
non-appealable order of a court of competent jurisdiction). This Section 6.3 shall not apply with respect
to  Taxes  other  than  any  Taxes  that  represent  losses,  claims,  damages,  etc.  arising  from  any  non-Tax
claim.      In  no  event  shall  any  Indemnified  Person  be  liable  on  any  theory  of  liability  for  any  special,
indirect,  consequential  or  punitive  damages  (including  any  loss  of  profits,  business  or  anticipated
savings). This Section 6.3 shall survive the repayment of indebtedness under, and otherwise shall survive
the expiration or other termination of, the Loan Agreement.

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be

that Borrower shall directly provide Agent all Financial Statements required to be delivered pursuant to
Section 7.1(b) and (c) hereunder.

7.2 Management  Rights.  Borrower  shall  permit  any  representative  that  Agent  or  Lender
authorizes,  including  its  attorneys  and  accountants,  to  inspect  the  Collateral  and  examine  and  make
copies  and  abstracts  of  the  books  of  account  and  records  of  Borrower  at  reasonable  times  and  upon

foregoing at the expense of the Borrower at any time during normal business hours and upon reasonable
advance notice. The Agent and Lender shall provide the Borrower with the opportunity to participate in
any  discussion  with  any  independent  accountants.      In  addition,  Agent  or  Lender  shall  be  entitled  at
reasonable  times  and  intervals  to  consult  with  and  advise  the  management  and  officers  of  Borrower
concerning  significant  business  issues  affecting  Borrower.  Such  consultations  shall  not  unreasonably
interfere  with  Borrower’s  business  operations.  The  parties  intend  that  the  rights  granted  Agent  and
Lender shall constitute “management rights” within the meaning of 29 C.F.R. Section 2510.3-101(d)(3)
(ii),  but  that  any  advice,  recommendations  or  participation  by  Agent  or  Lender  with  respect  to  any
business  issues  shall  not  be  deemed  to  give  Agent  or  Lender,  nor  be  deemed  an  exercise  by  Agent  or
Lender of, control over Borrower’s management or policies.

7.3

Further Assurances. Borrower shall from time to time execute, deliver and file, alone or
with  Agent,  any  financing  statements,  security  agreements,  collateral  assignments,  notices,  control
agreements, or other documents to perfect or give the highest priority to Agent’s Lien on the Collateral.
Borrower shall from time to time procure any instruments or documents as may be reasonably requested
by  Agent,  and  take  all  further  action  that  may  be  necessary,  or  that  Agent  may  reasonably  request,  to
perfect  and  protect  the  Liens  granted  hereby  and  thereby.  In  addition,  and  for  such  purposes  only,
Borrower  hereby  authorizes  Agent  to  execute  and  deliver  on  behalf  of  Borrower  and  to  file  such
financing  statements  (including  an  indication  that  the  financing  statement  covers  “all  assets  or  all
personal property” of Borrower in accordance with Section 9-504 of the UCC), collateral assignments,
notices, control agreements, security agreements and other documents without the signature of Borrower
either  in  Agent’s  name  or  in  the  name  of  Agent  as  agent  and  attorney-in-fact  for  Borrower.  Borrower
shall protect and defend Borrower’s title to the Collateral and Agent’s Lien thereon against all Persons
claiming any interest adverse to Borrower or Agent other than Permitted Liens.

7.4

with respect to any Indebtedness, or permit any Subsidiary so to do, other than Permitted Indebtedness,
or prepay any Indebtedness for borrowed money or take any

41

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

actions which impose on Borrower an obligation to prepay any Indebtedness for borrowed money, except
for (a) the conversion of Indebtedness into equity securities and the payment of cash in lieu of fractional
shares  in  connection  with  such  conversion,  (b)  purchase  money  Indebtedness  pursuant  to  its  then
applicable payment schedule, (c) prepayment by any Subsidiary of (i) intercompany Indebtedness owed
by  such  Subsidiary  to  any  Borrower,  or  (ii)  if  such  Subsidiary  is  not  a  Borrower,  intercompany
Indebtedness  owed  by  such  Subsidiary  to  another  Subsidiary  that  is  not  a  Borrower,  (d)  payment  of
regularly scheduled interest and principal payments (and fees, indemnities and expenses payable) as, and
when  due  in  respect  of  any  such  Indebtedness  to  the  extent  permitted  by  any  subordination  or
intercreditor provisions in respect thereof, (e) any extension, refinancing or renewal constitutes Permitted
Indebtedness or (f) as otherwise permitted hereunder or approved in writing by Agent.

other property and assets used in Borrower’s business or in which Borrower now or hereafter holds any
interest  free  and  clear  from  any  legal  process  reasonably  likely  to  result  in  liability  in  excess  of  Five
Hundred Thousand Dollars ($500,000) or Liens that materially affect the operation of such Borrower’s
business as currently conducted and proposed to be conducted by such Borrower (except for Permitted
Liens and except as to legal process, to the extent contested in good faith), and shall give Agent prompt
written  notice  of  any  legal  process  affecting  the  Collateral  or  the  Intellectual  Property  or  any  Liens
thereon, provided however, that the Collateral may be subject to Permitted Liens, except that there shall
be no Liens whatsoever on Intellectual Property, other than any Liens referred to in clauses (vii), (xv) and
(xviii) of the definition of Permitted Liens. Borrower shall not agree with any Person other than Agent or
Lender  not  to  encumber  its  property  except  in  accordance  with  the  provisions  of  this  Section  7.5.
Borrower shall not enter into or suffer to exist or become effective any agreement that prohibits or limits
the ability of any Borrower to create, incur, assume or suffer to exist any Lien upon any of its Collateral
or  Intellectual  Property,  whether  now  owned  or  hereafter  acquired,  to  secure  its  obligations  under  the
Loan Documents to which it is a party other than (a) this Agreement and the other Loan Documents, (b)
any  agreements  governing  any  purchase  money  Liens  or  capital  lease  obligations  otherwise  permitted
hereby  (in  which  case,  any  prohibition  or  limitation  shall  only  be  effective  against  the  assets  financed
thereby), (c) customary restrictions on the assignment of leases, licenses and other agreements, and (d)
restrictions and conditions imposed by (A) law or (B) any agreements evidencing Indebtedness permitted

such  Subsidiary’s  title  to  its  assets  from  and  against  all  Persons  claiming  any  interest  adverse  to  such
Subsidiary, and Borrower shall cause its Subsidiaries at all times to keep such Subsidiary’s property and
assets  free  and  clear  from  any  legal  process  reasonably  likely  to  result  in  liability  in  excess  of  Five
Hundred Thousand Dollars ($500,000) or Liens whatsoever (except for Permitted Liens and except as to
legal  process,  to  the  extent  contested  in  good  faith,  provided  however,  that  there  shall  be  no  Liens
whatsoever on Intellectual Property, other than any Liens referred to in clauses (vii), (xv) and (xviii) of
the definition of Permitted Liens), and

Thousand  Dollars  ($750,000)  in  any  fiscal  year,  provided  that  no  Event  of  Default  has  occurred,  is

deemed  to  occur  upon  the  cashless  exercise  of  stock  options  when  such  Equity  Interests  represents  a

connection with any dividend, split or combination thereof or (iii) to honor any conversion request by a

of  the  Secured  Obligations  together  with  a  Prepayment  Charge  (if  any)  and  declare  them  to  be
immediately  due  and  payable  (provided,  that  upon  the  occurrence  of  an  Event  of  Default  of  the  type
described  in  Section  9.5,  all  of  the  Secured  Obligations  (including,  without  limitation,  the  Prepayment
Charge (if any), the Existing End of Term Charge and the End of Term Charge) shall automatically be
accelerated and made due and payable, in each case without any further notice or act), (ii) Agent may, at
its  option,  sign  and  file  in  Borrower’s  name  any  and  all  collateral  assignments,  notices,  control
agreements,  security  agreements  and  other  documents  it  deems  necessary  or  appropriate  to  perfect  or
protect  the  repayment  of  the  Secured  Obligations,  and  in  furtherance  thereof,  Borrower  hereby  grants
Agent  an  irrevocable  power  of  attorney  coupled  with  an  interest,  and  (iii)  Agent  may  notify  any  of
Borrower’s  account  debtors  to  make  payment  directly  to  Agent,  compromise  the  amount  of  any  such
account  on  Borrower’s  behalf  and  endorse  Agent’s  name  without  recourse  on  any  such  payment  for
deposit  directly  to  Agent’s  account.  Agent  may,  and  at  the  direction  of  the  Required  Lenders  shall,
exercise  all  rights  and  remedies  with  respect  to  the  Collateral  under  the  Loan  Documents  or  otherwise
available  to  it  under  the  UCC  and  other  applicable  law,  including  the  right  to  release,  hold,  sell,  lease,

Default, Agent may, and at the direction of the Required Lenders shall, at any time or from time to time,
apply,  collect,  liquidate,  sell  in  one  or  more  sales,  lease  or  otherwise  dispose  of,  any  or  all  of  the
Collateral, in its then condition or following any commercially reasonable preparation or processing, in
such order as Agent may elect. Any such sale may be made either at public or private sale at its place of
business  or  elsewhere.  Borrower  agrees  that  any  such  public  or  private  sale  may  occur  upon  ten  (10)
calendar days’ prior written notice to Borrower. Agent may require Borrower to assemble the Collateral
and make it available to Agent at a place designated by Agent that is reasonably convenient to Agent and
Borrower. The proceeds of any sale, disposition or other realization upon all or any part of the Collateral
shall be applied by Agent in the following order of priorities:

First, to Agent and Lender in an amount sufficient to pay in full Agent’s and Lender’s reasonable
costs and professionals’ and advisors’ fees and expenses as described in Section 11.11;

Second,  to  Lender  in  an  amount  equal  to  the  then  unpaid  amount  of  the  Secured  Obligations
(including principal, interest, and any default rate interest pursuant to Section 2.4), in such order
and priority as Agent may choose in its sole discretion; and

Finally,  after  the  full  and  final  payment  in  Cash  of  all  of  the  Secured  Obligations  (other  than
inchoate obligations), to any creditor holding a junior Lien on the Collateral, or to Borrower or
its representatives or as a court of competent jurisdiction may direct.

Agent shall be deemed to have acted reasonably in the custody, preservation and disposition of any of the
Collateral if it complies with the obligations of a secured party under the UCC.

10.3 No  Waiver.  Agent  shall  be  under  no  obligation  to  marshal  any  of  the  Collateral  for  the
benefit  of  Borrower  or  any  other  Person,  and  Borrower  expressly  waives  all  rights,  if  any,  to  require
Agent to marshal any Collateral.

10.4 Cumulative  Remedies.  The  rights,  powers  and  remedies  of  Agent  hereunder  shall  be  in
addition  to  all  rights,  powers  and  remedies  given  by  statute  or  rule  of  law  and  are  cumulative.  The
exercise of any one or more of the rights, powers and remedies provided herein shall not be construed as
a waiver of or election of remedies with respect to any other rights, powers and remedies of Agent.

(y) in connection with a Lender’s own financing or securitization transactions, the restrictions set forth
herein  shall  not  apply  and  Agent  and  Lender  may  assign,  transfer  or  indorse  its  rights  hereunder  and
under the other Loan Documents to any Person or party providing such financing or formed to undertake
such  securitization  transaction  and  any  transferee  of  such  Person  or  party  upon  the  occurrence  of  a
default, event of default or similar occurrence with respect to such financing or securitization transaction;
provided that no such sale, transfer, pledge or assignment under this clause (y) shall release such Lender
from any of its obligations hereunder or substitute any such Person or party for such Lender as a party
hereto until Agent shall have received and accepted an effective assignment agreement from such Person
or party in form satisfactory to Agent executed, delivered and fully completed by the applicable parties
thereto, and shall have received such other information regarding such assignee as Agent reasonably shall
require. The Agent, acting solely for this purpose as an agent of Borrower, shall maintain at one of its
offices in the United States a register for the recordation of the names and addresses of each Lender, and
the  Term  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”). The entries in the Register shall
be  conclusive  absent  manifest  error,  and  the  Borrower,  the  Agent  and  Lender  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. The Register shall be available for inspection by Borrower and any Lender,
at any reasonable time and from time to time upon reasonable prior notice.

11.8 Governing Law. This Agreement and the other Loan Documents have been negotiated and
delivered  to  Agent  and  Lender  in  the  State  of  California,  and  shall  have  been  accepted  by  Agent  and
Lender in the State of California. Payment to Agent and Lender by Borrower of the Secured Obligations
is due in the State of California. This Agreement and the other Loan Documents shall be governed by,
and construed and enforced in accordance with, the laws of the State of California, excluding conflict of
laws principles that would cause the application of laws of any other jurisdiction.

11.9 Consent  to  Jurisdiction  and  Venue.  All  judicial  proceedings  (to  the  extent  that  the
reference requirement of Section 11.10 is not applicable) arising in or under or related to this Agreement
or any of the other Loan Documents may be brought in any state or federal court located in the State of
California.  By  execution  and  delivery  of 
this  Agreement,  each  party  hereto  generally  and
unconditionally:  (a)  consents  to  nonexclusive  personal  jurisdiction  in  Santa  Clara  County,  State  of
California; (b) waives any objection as to jurisdiction or venue in Santa Clara County, State of California;
(c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (d)
irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement or
the other Loan Documents. Service of process on any party hereto in any action arising out of or relating
to this Agreement shall be effective if given in accordance with the requirements for notice set forth in
Section 11.2, and shall be deemed

54

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

effective and received as set forth in Section 11.2. Nothing herein shall affect the right to serve process in
any  other  manner  permitted  by  law  or  shall  limit  the  right  of  either  party  to  bring  proceedings  in  the
courts of any other jurisdiction.

11.10 Mutual Waiver of Jury Trial / Judicial Reference.

(a)

Because  disputes  arising  in  connection  with  complex  financial  transactions  are  most
quickly and economically resolved by an experienced and expert Person and the parties wish applicable
state  and  federal  laws  to  apply  (rather  than  arbitration  rules),  the  parties  desire  that  their  disputes  be
resolved by a judge applying such applicable laws. EACH OF BORROWER, AGENT AND LENDER
SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF
ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER
CLAIM  (COLLECTIVELY,  “CLAIMS”)  ASSERTED  BY  BORROWER  AGAINST  AGENT,
LENDER  OR  THEIR  RESPECTIVE  ASSIGNEE  OR  BY  AGENT,  LENDER  OR  THEIR
RESPECTIVE ASSIGNEE AGAINST BORROWER. This waiver extends to all such Claims, including
Claims that involve Persons other than Agent, Borrower and Lender; Claims that arise out of or are in
any  way  connected  to  the  relationship  among  Borrower,  Agent  and  Lender;  and  any  Claims  for
damages,  breach  of  contract,  tort,  specific  performance,  or  any  equitable  or  legal  relief  of  any  kind,
arising out of this Agreement, any other Loan Document.

(b)

If the waiver of jury trial set forth in Section 11.10(a) is ineffective or unenforceable, the
parties  agree  that  all  Claims  shall  be  resolved  by  reference  to  a  private  judge  sitting  without  a  jury,
pursuant to Code of Civil Procedure Section 638, before a mutually acceptable referee or, if the parties
cannot  agree,  a  referee  selected  by  the  Presiding  Judge  of  the  Santa  Clara  County,  California.  Such
proceeding shall be conducted in Santa Clara County, California, with California rules of evidence and
discovery applicable to such proceeding.

(c)

In the event Claims are to be resolved by judicial reference, either party may seek from a
court identified in Section 11.9, any prejudgment order, writ or other relief and have such prejudgment
order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims
are otherwise subject to resolution by judicial reference.

11.11 Professional  Fees.  Borrower  promises  to  pay  Agent’s  and  Lender’s  fees  and  expenses
necessary  to  finalize  the  loan  documentation,  including  but  not  limited  to  reasonable  and  invoiced
attorneys’  fees,  UCC  searches,  filing  costs,  and  other  miscellaneous  expenses.  In  addition,  Borrower
promises  to  pay  any  and  all  reasonable  and  invoiced  attorneys’  and  other  professionals’  fees  and
expenses incurred by Agent and Lender after the Closing Date in connection with or related to: (a) the
Loan; (b) the administration, collection, or enforcement of the Loan; (c) the amendment or modification
of the Loan Documents; (d) any waiver, consent, release, or termination under the Loan Documents; (e)
the protection, preservation, audit, field exam, sale, lease, liquidation, or

55

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

disposition of Collateral or the exercise of remedies with respect to the Collateral; (f) any legal, litigation,
administrative,  arbitration,  or  out  of  court  proceeding  in  connection  with  or  related  to  Borrower  or  the
Collateral,  and  any  appeal  or  review  thereof;  and  (g)  any  bankruptcy,  restructuring,  reorganization,
assignment  for  the  benefit  of  creditors,  workout,  foreclosure,  or  other  action  related  to  Borrower,  the
Collateral, the Loan Documents, including representing Agent or Lender in any adversary proceeding or
contested matter commenced or continued by or on behalf of Borrower’s estate, and any appeal or review
thereof.

11.12 Confidentiality.  Agent  and  Lender  acknowledge  that  certain  items  of  Collateral  and
information provided to Agent and Lender by Borrower are confidential and proprietary information of
Borrower, if and to the extent such information either (x) is marked as confidential by Borrower at the
time  of  disclosure,  or  (y)  should  reasonably  be  understood  to  be  confidential  (the  “Confidential
Information”). Accordingly, Agent and Lender agree that any Confidential Information it may obtain in
the course of acquiring, administering, or perfecting Agent’s security interest in the Collateral shall not
be  disclosed  to  any  other  Person  or  entity  in  any  manner  whatsoever,  in  whole  or  in  part,  without  the
prior written consent of Borrower, except that Agent and Lender may disclose any such information: (a)
to its own directors, officers, employees, accountants, counsel and other professional advisors and to its
Affiliates if Agent or Lender in their sole discretion determines that any such party should have access to
such  information  in  connection  with  such  party’s  responsibilities  in  connection  with  the  Loan  or  this
Agreement  and,  provided  that  such  recipient  of  such  Confidential  Information  either  (i)  agrees  to  be
bound  by  the  confidentiality  provisions  of  this  paragraph  or  (ii)  is  otherwise  subject  to  confidentiality
restrictions  that  reasonably  protect  against  the  disclosure  of  Confidential  Information;  (b)  if  such
information is generally available to the public; (c) if required or appropriate in any report, statement or
testimony submitted to any governmental authority having or claiming to have jurisdiction over Agent or
Lender; (d) if required or appropriate in response to any summons or subpoena or in connection with any
litigation, to the extent permitted or deemed advisable by Agent’s or Lender’s counsel; (e) to comply with
any  legal  requirement  or  law  applicable  to  Agent  or  Lender;  (f)  to  the  extent  reasonably  necessary  in
connection with the exercise of any right or remedy under any Loan Document, including Agent’s sale,
lease, or other disposition of Collateral after default; (g) to any participant or assignee of Agent or Lender
or  any  prospective  participant  or  assignee;  provided,  that  such  participant  or  assignee  or  prospective
participant or assignee agrees in writing to be bound by this Section prior to disclosure; or (h) otherwise
with  the  prior  consent  of  Borrower;  provided,  that  any  disclosure  made  in  violation  of  this  Agreement
shall not affect the obligations of Borrower or any of its Affiliates or any guarantor under this Agreement
or the other Loan Documents.

11.13 Assignment  of  Rights.  Borrower  acknowledges  and  understands  that  Agent  or  Lender
may,  subject  to  Section  11.7,  sell  and  assign  all  or  part  of  its  interest  hereunder  and  under  the  Loan
Documents to any Person or entity (an “Assignee”). After such assignment the term “Agent” or “Lender”
as used in the Loan Documents shall mean

56

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

and  include  such  Assignee,  and  such  Assignee  shall  be  vested  with  all  rights,  powers  and  remedies  of
Agent and Lender hereunder with respect to the interest so assigned; but with respect to any such interest
not so transferred, Agent and Lender shall retain all rights, powers and remedies hereby given. No such
assignment by Agent or Lender shall relieve Borrower of any of its obligations hereunder. Lender agrees
that in the event of any transfer by it of the Note(s)(if any), it will endorse thereon a notation as to the
portion of the principal of the Note(s), which shall have been paid at the time of such transfer and as to
the date to which interest shall have been last paid thereon.

11.14 Revival of Secured Obligations. This Agreement and the Loan Documents shall remain in
full  force  and  effect  and  continue  to  be  effective  if  any  petition  is  filed  by  or  against  Borrower  for
liquidation or reorganization, if Borrower becomes insolvent or makes an assignment for the benefit of
creditors, if a receiver or trustee is appointed for all or any significant part of Borrower’s assets, or if any
payment  or  transfer  of  Collateral  is  recovered  from  Agent  or  Lender.  The  Loan  Documents  and  the
Secured  Obligations  and  Collateral  security  shall  continue  to  be  effective,  or  shall  be  revived  or
reinstated, as the case may be, if at any time payment and performance of the Secured Obligations or any
transfer of Collateral to Agent, or any part thereof is rescinded, avoided or avoidable, reduced in amount,
or must otherwise be restored or returned by, or is recovered from, Agent, Lender or by any obligee of
the Secured Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all
as though such payment, performance, or transfer of Collateral had not been made. In the event that any
payment, or any part thereof, is rescinded, reduced, avoided, avoidable, restored, returned, or recovered,
the  Loan  Documents  and  the  Secured  Obligations  shall  be  deemed,  without  any  further  action  or
documentation, to have been revived and reinstated except to the extent of the full, final, and indefeasible
payment to Agent or Lender in Cash.

11.15 Counterparts.  This  Agreement  and  any  amendments,  waivers,  consents  or  supplements
hereto  may  be  executed  in  any  number  of  counterparts,  and  by  different  parties  hereto  in  separate
counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts
shall constitute but one and the same instrument.

11.16 No Third Party Beneficiaries. No provisions of the Loan Documents are intended, nor will
be interpreted, to provide or create any third-party beneficiary rights or any other rights of any kind in
any  Person  other  than  Agent,  Lender  and  Borrower  unless  specifically  provided  otherwise  herein,  and,
except as otherwise so provided, all provisions of the Loan Documents will be personal and solely among
Agent, the Lender and the Borrower.

11.17 Agency.

(a)

Lender  hereby  irrevocably  appoints  Hercules  Capital,  Inc.  to  act  on  its  behalf  as  the

the Agent by the terms hereof or thereof, together with such actions and powers as are reasonably
incidental thereto.

(b)

Lender agrees to indemnify the Agent in its capacity as such (to the extent not reimbursed

which  indemnification  is  sought  under  this  Section  11.17,  from  and  against  any  and  all  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits,  costs,  expenses  or  disbursements  of
any kind whatsoever that may at any time be imposed on, incurred by or asserted against the Agent in
any  way  relating  to  or  arising  out  of,  this  Agreement,  any  of  the  other  Loan  Documents  or  any
documents contemplated by or referred to herein or therein or the transactions contemplated hereby or
thereby or any action taken or omitted by the Agent under or in connection with any of the foregoing;
The  agreements  in  this  Section  shall  survive  the  payment  of  the  Loans  and  all  other  amounts  payable

(c)

the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as

default or any Event of Default has occurred and is continuing;

(ii)

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  Agent  is  required  to  exercise  as  directed  in  writing  by  the  Lender,
provided that the Agent shall not be required to take any action that, in its opinion or the opinion
of  its  counsel,  may  expose  the  Agent  to  liability  or  that  is  contrary  to  any  Loan  Document  or
applicable law; and

(iii)

except as expressly set forth herein and in the other Loan Documents, have any
duty  to  disclose,  and  the  Agent  shall  not  be  liable  for  the  failure  to  disclose,  any  information

competitively harmful if publicly disclosed.

misconduct.

The 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  or  Event  of  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 Section 4 or elsewhere herein, other than to confirm receipt of
items expressly required to be delivered to the Agent.

(g)

Reliance by Agent. Agent may rely, and shall be fully protected in acting, or refraining to
act,  upon,  any  resolution,  statement,  certificate,  instrument,  opinion,  report,  notice,  request,  consent,
order, bond or other paper or document that it has no reason to believe to be other than genuine and to
have  been  signed  or  presented  by  the  proper  party  or  parties  or,  in  the  case  of  cables,  telecopies  and
telexes, to have been sent by the proper party or parties. In the absence of its gross negligence or willful
misconduct,  Agent  may  conclusively  rely,  as  to  the  truth  of  the  statements  and  the  correctness  of  the
opinions expressed therein, upon any certificates or opinions furnished to Agent and conforming to the
requirements  of  the  Loan  Agreement  or  any  of  the  other  Loan  Documents.  Agent  may  consult  with
counsel, and any opinion or legal advice of such counsel shall be full and complete authorization and
protection in respect of any action taken, not taken or suffered by Agent hereunder or under any Loan
Documents  in  accordance  therewith.  Agent  shall  have  the  right  at  any  time  to  seek  instructions
concerning the administration of the Collateral from any court of competent jurisdiction. Agent shall not
be under any obligation to exercise any of the rights or powers granted to Agent by this Agreement, the
Loan Agreement and the other Loan Documents at the request or direction of Lenders unless Agent shall
have  been  provided  by  Lender  with  adequate  security  and  indemnity  against  the  costs,  expenses  and
liabilities that may be incurred by it in compliance with such request or direction.

11.18 Publicity.  None  of  the  parties  hereto  nor  any  of  its  respective  member  businesses  and
Affiliates shall, without the other parties’ prior written consent (which shall not be unreasonably withheld
or delayed), publicize or use (a) the other party’s name (including a brief description of the relationship
among  the  parties  hereto),  logo  or  hyperlink  to  such  other  parties’  web  site,  separately  or  together,  in
written  and  oral  presentations,  advertising,  promotional  and  marketing  materials,  client  lists,  public

such other parties in the Publicity Materials; and (c) such other parties’ name, trademarks, servicemarks
in any news or press release concerning such party; provided however, notwithstanding anything to the

requirements  or  laws  applicable  to  such  party,  pursuant  to  any  listing  agreement  with  any  national
securities  exchange  (so  long  as  such  party  provides  prior  notice  to  the  other  party  hereto  to  the  extent
reasonably practicable) and (ii) to comply with Section 11.12.

11.19 Multiple Borrowers.

(a)

Borrower’s Agent. Each of the Borrowers hereby irrevocably appoints Parent as its agent,
attorney-in-fact and legal representative for all purposes, including requesting disbursement of the Term
Loan and receiving account statements and other notices and communications to Borrowers (or any of
them) from the Agent or any Lender. The Agent may rely, and shall be fully protected in relying, on any
request  for  the  Term  Loan,  disbursement  instruction,  report,  information  or  any  other  notice  or
communication made or given by Parent, whether in its own name or on behalf of one or more of the
other  Borrowers,  and  the  Agent  shall  not  have  any  obligation  to  make  any  inquiry  or  request  any
confirmation from or on behalf of any other Borrower as to the binding effect on it of any such request,
instruction, report, information, other notice or communication, nor shall the joint and several character
of the Borrowers’ obligations hereunder be affected thereby.

(b) Waivers. Each Borrower hereby waives: (i) any right to require the Agent to institute suit
against,  or  to  exhaust  its  rights  and  remedies  against,  any  other  Borrower  or  any  other  person,  or  to
proceed against any property of any kind which secures all or any part of the Secured Obligations, or to
exercise any right of offset or other right with respect to any reserves, credits or deposit accounts held by
or maintained with the Agent or any Indebtedness of the Agent or any Lender to any other Borrower, or
to exercise any other right or power, or pursue any other remedy the Agent or any Lender may have; (ii)
any defense arising by reason of any disability or other defense of any other Borrower or any guarantor
or any endorser, co-maker or other person, or by reason of the cessation from any cause whatsoever of
any  liability  of  any  other  Borrower  or  any  guarantor  or  any  endorser,  co-maker  or  other  person,  with
respect to all or any part of the Secured Obligations, or by reason of any act or omission of the Agent or
others  which  directly  or  indirectly  results  in  the  discharge  or  release  of  any  other  Borrower  or  any
guarantor or any other person or any Secured Obligations or any security therefor, whether by operation
of  law  or  otherwise;  (iii)  any  defense  arising  by  reason  of  any  failure  of  the  Agent  to  obtain,  perfect,
maintain  or  keep  in  force  any  Lien  on,  any  property  of  any  Borrower  or  any  other  person;  (iv)  any
defense  based  upon  or  arising  out  of  any  bankruptcy,  insolvency,  reorganization,  arrangement,
readjustment  of  debt,  liquidation  or  dissolution  proceeding  commenced  by  or  against  any  other
Borrower or any guarantor or any endorser, co-maker or other person, including without limitation any
discharge of, or bar against collecting, any of the Secured Obligations (including without limitation any
interest thereon), in or as a result of any such proceeding. Until all of the Secured Obligations have been
paid, performed, and discharged in full, nothing shall discharge or satisfy the liability of any Borrower
hereunder  except  the  full  performance  and  payment  of  all  of  the  Secured  Obligations.  If  any  claim  is
ever made upon the Agent for repayment or recovery of any amount or amounts received by the Agent
in payment of or

60

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

on account of any of the Secured Obligations, because of any claim that any such payment constituted a
preferential transfer or fraudulent conveyance, or for any other reason whatsoever, and the Agent repays
all or part of said amount by reason of any judgment, decree or order of any court or administrative body
having jurisdiction over the Agent or any of its property, or by reason of any settlement or compromise
of any such claim effected by the Agent with any such claimant (including without limitation the any
other  Borrower),  then  and  in  any  such  event,  each  Borrower  agrees  that  any  such  judgment,  decree,
order, settlement and compromise shall be binding upon such Borrower, notwithstanding any revocation
or release of this Agreement or the cancellation of any note or other instrument evidencing any of the
Secured Obligations, or any release of any of the Secured Obligations, and each Borrower shall be and
remain liable to the Agent and the Lenders under this Agreement for the amount so repaid or recovered,
to the same extent as if such amount had never originally been received by the Agent or any Lender, and
the provisions of this sentence shall survive, and continue in effect, notwithstanding any revocation or
release  of  this  Agreement.  Each  Borrower  hereby  expressly  and  unconditionally  waives  all  rights  of
subrogation, reimbursement and indemnity of every kind against any other Borrower, and all rights of
recourse to any assets or property of any other Borrower, and all rights to any collateral or security held
for the payment and performance of any Secured Obligations, including (but not limited to) any of the
foregoing rights which Borrower may have under any present or future document or agreement with any
other Borrower or other person, and including (but not limited to) any of the foregoing rights which any
Borrower may have under any equitable doctrine of subrogation, implied contract, or unjust enrichment,
or any other equitable or legal doctrine.

(c)

Consents.  Each  Borrower  hereby  consents  and  agrees  that,  without  notice  to  or  by
Borrower  and  without  affecting  or  impairing  in  any  way  the  obligations  or  liability  of  Borrower
hereunder, the Agent may, from time to time before or after revocation of this Agreement, do any one or
more of the following in its sole and absolute discretion: (i) accept partial payments of, compromise or
settle,  renew,  extend  the  time  for  the  payment,  discharge,  or  performance  of,  refuse  to  enforce,  and
release all or any parties to, any or all of the Secured Obligations; (ii) grant any other indulgence to any
Borrower or any other Person in respect of any or all of the Secured Obligations or any other matter; (iii)
accept,  release,  waive,  surrender,  enforce,  exchange,  modify,  impair,  or  extend  the  time  for  the
performance,  discharge,  or  payment  of,  any  and  all  property  of  any  kind  securing  any  or  all  of  the
Secured Obligations or any guaranty of any or all of the Secured Obligations, or on which the Agent at
any  time  may  have  a  Lien,  or  refuse  to  enforce  its  rights  or  make  any  compromise  or  settlement  or
agreement therefor in respect of any or all of such property; (iv) substitute or add, or take any action or
omit  to  take  any  action  which  results  in  the  release  of,  any  one  or  more  other  Borrowers  or  any
endorsers or guarantors of all or any part of the Secured Obligations, including, without limitation one
or  more  parties  to  this  Agreement,  regardless  of  any  destruction  or  impairment  of  any  right  of
contribution  or  other  right  of  Borrower;  (v)  apply  any  sums  received  from  any  other  Borrower,  any
guarantor,  endorser,  or  co-signer,  or  from  the  disposition  of  any  Collateral  or  security,  to  any
Indebtedness whatsoever

61

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

owing from such person or secured by such Collateral or security, in such manner and order as the Agent
determines  in  its  sole  discretion,  and  regardless  of  whether  such  Indebtedness  is  part  of  the  Secured
Obligations, is secured, or is due and payable. Each Borrower consents and agrees that the Agent shall
be under no obligation to marshal any assets in favor of Borrower, or against or in payment of any or all
of  the  Secured  Obligations.  Each  Borrower  further  consents  and  agrees  that  the  Agent  shall  have  no
duties  or  responsibilities  whatsoever  with  respect  to  any  property  securing  any  or  all  of  the  Secured
Obligations.      Without  limiting  the  generality  of  the  foregoing,  the  Agent  shall  have  no  obligation  to
monitor,  verify,  audit,  examine,  or  obtain  or  maintain  any  insurance  with  respect  to,  any  property
securing any or all of the Secured Obligations.

(d)

Independent  Liability.  Each  Borrower  hereby  agrees  that  one  or  more  successive  or
concurrent actions may be brought hereon against such Borrower, in the same action in which any other
Borrower may be sued or in separate actions, as often as deemed advisable by Agent. Each Borrower is
fully  aware  of  the  financial  condition  of  each  other  Borrower  and  is  executing  and  delivering  this
Agreement based solely upon its own independent investigation of all matters pertinent hereto, and such
Borrower is not relying in any manner upon any representation or statement of the Agent or any Lender
with respect thereto. Each Borrower represents and warrants that it is in a position to obtain, and each
Borrower  hereby  assumes  full  responsibility  for  obtaining,  any  additional  information  concerning  any
other Borrower’s financial condition and any other matter pertinent hereto as such Borrower may desire,
and such Borrower is not relying upon or expecting the Agent to furnish to it any information now or
hereafter in the Agent’s possession concerning the same or any other matter.

(e)

Subordination. All Indebtedness of a Borrower now or hereafter arising held by another
Borrower is subordinated to the Secured Obligations and the Borrower holding the Indebtedness shall
take  all  actions  reasonably  requested  by  Agent  to  effect,  to  enforce  and  to  give  notice  of  such
subordination.

11.20 Amendment  and  Restatement;  No  Novation.  Borrower,  Agent  and  the  Lenders,  each
hereby agree that, effective upon the execution and delivery of this Agreement by each such party, the
terms and provisions of the Existing Loan Agreement and each other Loan Document entered into prior

restated  and  superseded  in  their  entirety  by  the  terms  and  provisions  of  this  Agreement  and  the  other
Loan  Documents.      Notwithstanding  the  foregoing,  nothing  herein  contained  shall  be  construed  as  a
substitution  or  novation  of  the  obligations  of  the  Borrower  outstanding  under  the  Existing  Loan
Documents  or  instruments,  documents  or  other  agreements  securing  the  same,  which  obligations  shall
remain in full force and effect, except to the extent that the terms thereof are specifically modified hereby
or by instruments, documents or other agreements executed concurrently herewith. Nothing expressed or

ADDENDUM 1 to LOAN AND SECURITY AGREEMENT

(a)

Borrower’s  Business.  For  purposes  of  this  Addendum  1,  Borrower  shall  be  deemed  to
include  its  “affiliates”  as  defined  in  Title  13  Code  of  Federal  Regulations  Section  121.103.  Borrower
represents and warrants to Agent and Lender as of the Closing Date and covenants to Agent and Lender
for a period of one year after the Closing Date with respect to subsections 2, 3, 4, 5, 6 and 7 below, as
follows:

1.

2.

3.

4.

5.

Size Status. Borrower’s primary NAICS code is 541714 and has less than 1,000
employees in the aggregate;

No  Relender.  Borrower’s  primary  business  activity  does  not  involve,  directly  or
indirectly,  providing  funds  to  others,  purchasing  debt  obligations,  factoring,  or
long-term leasing of equipment with no provision for maintenance or repair;

No Passive Business. Borrower is engaged in a regular and continuous business
operation (excluding the mere receipt of payments such as dividends, rents, lease
payments, or royalties). Borrower’s employees are carrying on the majority of day
to day operations. Borrower will not pass through substantially all of the proceeds
of the Loan to another entity;

No Real Estate Business. Borrower is not classified under Major Group 65 (Real
Estate)  or  Industry  No.  1531  (Operative  Builders)  of  the  SIC  Manual.  The
proceeds of the Loan will not be used to acquire or refinance real property unless
Borrower (x) is acquiring an existing property and will use at least 51 percent of
the usable square footage for its business purposes; (y) is building or renovating a
building  and  will  use  at  least  67  percent  of  the  usable  square  footage  for  its
business  purposes;  or  (z)  occupies  the  subject  property  and  uses  at  least  67
percent of the usable square footage for its business purposes.

No  Project  Finance.  Borrower’s  assets  are  not  intended  to  be  reduced  or
consumed,  generally  without  replacement,  as  the  life  of  its  business  progresses,
and  the  nature  of  Borrower’s  business  does  not  require  that  a  stream  of  cash
payments be made to the business’s financing sources, on a basis associated with
the continuing sale of assets (e.g., real estate development projects and oil and gas
wells). The primary purpose of the Loan is not to fund production of a single item
or defined limited number of items,

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

generally over a defined production period, where such production will constitute
the  majority  of  the  activities  of  Borrower  (e.g.,  motion  pictures  and  electric
generating plants).

6.

7.

No  Farm  Land  Purchases.  Borrower  will  not  use  the  proceeds  of  the  Loan  to
acquire  farm  land  which  is  or  is  intended  to  be  used  for  agricultural  or  forestry
purposes, such as the production of food, fiber, or wood, or is so taxed or zoned.

No Foreign Investment. The proceeds of the Loan will not be used substantially
for a foreign operation. At the time of the Loan, Borrower will not have more than
49 percent of its employees or tangible assets located outside the United States of
America.  The  representation  in  this  subsection  (7)  is  made  only  as  of  the  date
hereof and shall not continue for one year as contemplated in the first sentence of
this Section 1.

(b)

Small  Business  Administration  Documentation.  Agent  and  Lender  acknowledge  that
Borrower completed, executed and delivered to Agent SBA Forms 480, 652 and 1031 (Parts A and B)
together  with  a  business  plan  showing  Borrower’s  financial  projections  (including  balance  sheets  and
income  and  cash  flows  statements)  for  the  period  described  therein  and  a  written  statement  (whether
included  in  the  purchase  agreement  or  pursuant  to  a  separate  statement)  from  Agent  regarding  its
intended  use  of  proceeds  from  the  sale  of  securities  to  Lender  (the  “Use  of  Proceeds  Statement”).
Borrower represents and warrants to Agent and Lender that the information regarding Borrower and its
affiliates set forth in the SBA Form 480, Form 652 and Form 1031 and the Use of Proceeds Statement
delivered as of the Closing Date is accurate and complete.

(c)

Inspection. The following covenants contained in this  Section (c)  are intended to 

supplement and not to restrict the related provisions of the Loan Documents. Subject to the preceding 
sentence, Borrower will permit, for so long as Lender holds any debt or equity securities of Borrower, 
Agent, Lender or their representative, at Agent’s or Lenders’ expense, and examiners of the SBA to visit 
and inspect the properties and assets of Borrower, to examine its books of account and records, and to 
discuss Borrower’s affairs, finances and accounts with Borrower’s officers, senior management and 
accountants, all at such reasonable times as may be requested by Agent or Lender or the SBA.

(d)

Annual Assessment. Promptly after the end of each calendar year (but in any event prior
to  February  28  of  each  year)  and  at  such  other  times  as  may  be  reasonably  requested  by  Agent  or
Lender,  Borrower  will  deliver  to  Agent  a  written  assessment  of  the  economic  impact  of  Lender’s
investment in Borrower, specifying the full-time equivalent jobs created or retained in connection with
the investment, the impact of the investment

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be
competitively harmful if publicly disclosed.

on  the  businesses  of  Borrower  in  terms  of  expanded  revenue  and  taxes,  other  economic  benefits
resulting from the investment (such as technology development or commercialization, minority business
development,  or  expansion  of  exports)  and  such  other  information  as  may  be  required  regarding
Borrower in connection with the filing of Lender’s SBA Form 468.   Lender will assist Borrower with
preparing such assessment. In addition to any other rights granted hereunder, Borrower will grant Agent
and Lender and the SBA access to Borrower’s books and records for the purpose of verifying the use of
such  proceeds.  Borrower  also  will  furnish  or  cause  to  be  furnished  to  Agent  and  Lender  such  other
information regarding the business, affairs and condition of Borrower as Agent or Lender may from time
to time reasonably request.

(e)

Use  of  Proceeds.  Borrower  will  use  the  proceeds  from  the  Loan  only  for  purposes  set
forth  in  Section  7.17.  Borrower  will  deliver  to  Agent  from  time  to  time  promptly  following  Agent’s
request,  a  written  report,  certified  as  correct  by  Borrower’s  Chief  Financial  Officer,  verifying  the
purposes and amounts for which proceeds from the Loan have been disbursed. Borrower will supply to
Agent such additional information and documents as Agent reasonably requests with respect to its use of
proceeds and will permit Agent and Lender and the SBA to have access to any and all Borrower records
and information and personnel as Agent deems necessary to verify how such proceeds have been or are
being used, and to assure that the proceeds have been used for the purposes specified in Section 7.17.

(f)

Activities and Proceeds. Neither Borrower nor any of its affiliates (if any) will engage in
any activities or use directly or indirectly the proceeds from the Loan for any purpose for which a small
business investment company is prohibited from providing funds by the SBIC Act, including 13 C.F.R.
§107.720.  Without  obtaining  the  prior  written  approval  of  Agent,  Borrower  will  not  change  within  1
year  of  the  date  hereof,  Borrower’s  current  business  activity  to  a  business  activity  which  a  licensee
under the SBIC Act is prohibited from providing funds by the SBIC Act.

(g)

Redemption Provisions. Notwithstanding  any  provision  to  the  contrary  contained  in  the
Certificate of Incorporation of Borrower, as amended from time to time (the “Charter”), if, pursuant to
the  redemption  provisions  contained  in  the  Charter,  Lender  is  entitled  to  a  redemption  of  its  Warrant,
such redemption (in the case of Lender) will be at a price equal to the redemption price set forth in the
Charter  (the  “Existing  Redemption  Price”).      If,  however,  Lender  delivers  written  notice  to  Borrower
that  the  then  current  regulations  promulgated  under  the  SBIC  Act  prohibit  payment  of  the  Existing
Redemption Price in the case of an SBIC (or, if applied, the Existing Redemption Price would cause the
applicable  stock  to  lose  its  classification  as  an  “equity  security”  and  Lender  has  determined  that  such
classification is unadvisable), the amount Lender will be entitled to receive shall be the greater of (i) fair
market  value  of  the  securities  being  redeemed  taking  into  account  the  rights  and  preferences  of  such
securities plus any costs and expenses of the Lender incurred in making or maintaining

Certain identified information has been excluded from the document because it is both (i) not material and (ii) would be

the Warrant, and (ii) the Existing Redemption Price where the amount of accrued but unpaid dividends
payable  to  the  Lender  is  limited  to  Borrower’s  earnings  plus  any  costs  and  expenses  of  the  Lender
incurred in making or maintaining the Warrant; provided, however, the amount calculated in subsections
(i) or (ii) above shall not exceed the Existing Redemption Price.

(h)

Compliance and Resolution.   Borrower agrees that a failure to comply with Borrower’s
obligations under this Addendum, or any other set of facts or circumstances where it has been asserted
by any governmental regulatory agency (or Agent or Lender believes that there is a substantial risk of
such assertion) that Agent, Lender and their affiliates are not entitled to hold, or exercise any significant
right  with  respect  to,  any  securities  issued  to  Lender  by  Borrower,  will  constitute  a  breach  of  the
obligations  of  Borrower  under  the  financing  agreements  among  Borrower,  Agent  and  Lender.  In  the
event of (i) a failure to comply with Borrower’s obligations under this Addendum; or (ii) an assertion by
any governmental regulatory agency (or Agent or Lender believes that there is a substantial risk of such
assertion)  of  a  failure  to  comply  with  Borrower’s  obligations  under  this  Addendum,  then  (i)  Agent,
Lender and Borrower will meet and resolve any such issue in good faith to the satisfaction of Borrower,
Agent,  Lender,  and  any  governmental  regulatory  agency,  and  (ii)  upon  request  of  Lender  or  Agent,
Borrower  will  cooperate  and  assist  with  any  assignment  of  the  financing  agreements  among  Hercules
Capital, Inc., Hercules Private Credit Fund I L.P. and Hercules Private Global Venture Growth Fund I
L.P.

NOW THEREFORE, Subsidiary and Agent agree as follows:

AGREEMENT

1. The  recitals  set  forth  above  are  incorporated  into  and  made  part  of  this  Joinder  Agreement.  Capitalized

2. By  signing  this  Joinder  Agreement,  Subsidiary  shall  be  bound  by  the  terms  and  conditions  of  the  Loan
Agreement  the  same  as  if  it  were  the  Borrower  (as  defined  in  the  Loan  Agreement)  under  the  Loan
Agreement,  mutatis  mutandis,  provided  however,  that  (a)  with  respect  to  (i)  Section  5.1  of  the  Loan

4. Subsidiary acknowledges that it benefits, both directly and indirectly, from the Loan Agreement, and hereby
waives,  for  itself  and  on  behalf  on  any  and  all  successors  in  interest  (including  without  limitation  any
assignee for the benefit of creditors, receiver, bankruptcy trustee or itself as debtor-in-possession under any

enforcement of this Joinder Agreement on the basis that (a) it failed to receive adequate consideration for
the execution and delivery of this Joinder Agreement or (b) its obligations under this Joinder Agreement are
avoidable as a fraudulent conveyance.

5. As security for the prompt, complete and indefeasible payment when due (whether on the payment dates or
otherwise) of all the Secured Obligations, Subsidiary grants to Agent a security interest in all of Subsidiary’s

WHEREAS, TG Therapeutics, Inc., a Delaware corporation (the “Company”), has entered into an Amended and

Restated Loan and Security Agreement of even date herewith (as amended and in effect from time to time, the “Loan
Agreement”) with Hercules Capital, Inc., a Maryland corporation, in its capacity as administrative and collateral agent,
Hercules Capital, Inc., as a lender (the “Warrantholder”), and the other lenders from time to time party thereto;

WHEREAS, pursuant to the Loan Agreement and as additional consideration to the Warrantholder for,
among other things, its agreements in the Loan Agreement, the Company has agreed to issue to the Warrantholder this
Warrant Agreement, evidencing the right to purchase shares of the Company’s Common Stock (this “Warrant”, “Warrant
Agreement”, or this “Agreement”);

NOW, THEREFORE, in consideration of the Warrantholder having executed and delivered the Loan

Agreement and provided the financial accommodations contemplated therein, and in consideration of the mutual covenants
and agreements contained herein, the Company and Warrantholder agree as follows:

SECTION 1. GRANT OF THE RIGHT TO PURCHASE COMMON STOCK.

up to the aggregate number of fully paid and non-assessable shares of Common Stock (as defined below) as determined 
pursuant to Section 1(b) below, at a purchase price per share equal to the Exercise Price (as defined below).  The number and 
Exercise Price of such shares are subject to adjustment as provided in Section 8.  As used herein, the following terms shall 
have the following meanings:

Company or a subsidiary pursuant to an equity option, equity purchase, or similar plan; (ii) a registration relating to
an SEC Rule 145 transaction; or (iii) a registration on any form that does not include substantially the same
information as would be required to be included in a registration statement covering the sale of the Registrable
Securities, provided that, for the avoidance of doubt, the inclusion of information regarding this Warrant and the
plan of distribution of and selling securityholder information related to the Common Shares issuable upon exercise
of this Warrant, shall not constitute a basis for excluding the Registrable Securities from a registration pursuant to
this clause (iii).

“Exercise Price”  means $17.95, subject to adjustment from time to time in accordance with the provisions

of this Warrant.

“Liquid Sale” means the closing of a Merger Event in which the consideration received by the Company

and/or its stockholders, as applicable, consists solely of cash and/or Marketable Securities.

“Marketable Securities” in connection with a Merger Event means securities meeting all of the following

requirements: (i) the issuer thereof is then subject to the reporting requirements of Section 13 or Section 15(d) of the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is then current in its filing of all required
reports and other information under the Act and the Exchange Act; (ii) the class and series of shares or other security
of the issuer that would be received by the Warrantholder in connection with the Merger Event were the
Warrantholder to exercise this Warrant on or prior to the closing thereof is then traded on a national securities
exchange or over-the-counter market, and (iii) following the closing of such Merger Event, the Warrantholder would
not be restricted from publicly re-selling all of the issuer’s shares and/or other securities that would be received by
the Warrantholder in such Merger Event were the Warrantholder to exercise this Warrant in full on or prior to the
closing of such Merger Event, except to the extent that any such restriction (x) arises solely under federal or state
securities laws, rules or regulations, and (y) does not extend beyond six (6) months from the closing of such Merger
Event.

“Merger Event” means any of the following: (i) a sale, lease or other transfer of all or substantially all assets
of the Company, (ii) any merger or consolidation involving the Company in which the Company is not the surviving
entity or in which the outstanding shares of the Company’s capital stock are otherwise converted into or exchanged
for shares of capital stock or other securities or property of another entity, or (iii) any sale by holders of the
outstanding voting equity securities of the Company in a single transaction or series of related transactions of shares
constituting a majority of the outstanding combined voting power of the Company.

“Purchase Price” means, with respect to any exercise of this Warrant, an amount equal to the then-effective

Exercise Price multiplied by the number of shares of Common Stock as to which this Warrant is then exercised.

2

“Registrable Securities” means (i) the shares issuable upon exercise of this Warrant and (ii) any other
Common Shares issued as a dividend or other distribution with respect to, in exchange for or in replacement of such
shares; provided that the securities referred to in (i)-(ii) above shall cease to be Registrable Securities (A) upon the

144.

“Warrant Coverage” means 2.95% times the aggregate principal amount of Term Loan Advances (as defined

the quotient derived by dividing (i) the Warrant Coverage by (ii) the Exercise Price, subject to adjustment from time to time
in accordance with the provisions of this Warrant.

SECTION 2. TERM OF THE AGREEMENT.

The term of this Agreement and the right to purchase Common Stock as granted herein shall commence on

the Effective Date and, subject to Section 8(a) below, shall be exercisable until 5:00 p.m. (Eastern Time) on the seventh (7th)
anniversary of the Effective Date.

SECTION 3. EXERCISE OF THE PURCHASE RIGHTS.

(a)

Exercise.  The purchase rights set forth in this Agreement are exercisable by the Warrantholder, in whole or 

in part, at any time, or from time to time, prior to the expiration of the term set forth in Section 2, by tendering to the 
Company at its principal office a notice of exercise in the form attached hereto as Exhibit I (the “Notice of Exercise”), duly 
completed and executed.  Promptly upon receipt of the Notice of Exercise and the payment of the Purchase Price in 
accordance with the terms set forth below, and in no event later than three (3) business days thereafter, the Company or its 
transfer agent shall either (i) issue to the Warrantholder a certificate for the number of shares of Common Stock purchased or 
(ii) credit the same via book entry to the Warrantholder, and the Company shall execute the acknowledgment of exercise in 
the form attached hereto as Exhibit II (the “Acknowledgment of Exercise”) indicating the number of shares which remain
subject to future purchases under this Warrant, if any.

The Purchase Price may be paid at the Warrantholder’s election either (i) by cash or check, or (ii) by
surrender of all or a portion of the Warrant for shares of Common Stock to be exercised under this Agreement and, if
applicable, an amended Agreement setting forth the remaining number of shares purchasable hereunder, as determined
below (“Net Issuance”).  If the Warrantholder elects the Net Issuance method, the Company will issue shares of Common 
Stock in accordance with the following formula:

X = Y(A-B)
            A

Where:

X = 

Y = 

the number of shares of Common Stock to be issued to the Warrantholder.

the number of shares of Common Stock requested to be exercised under this Agreement.

3

the then-current fair market value of one (1) share of Common Stock at the time of exercise of this

A = 
Warrant.

B = 

the then-effective Exercise Price.

For purposes of the above calculation, the current fair market value of shares of Common Stock shall mean with

respect to each share of Common Stock:

(i)

at all times when the Common Stock is traded on a national securities exchange, inter-dealer

quotation system or over-the-counter bulletin board service, the average of the closing prices over a five (5) day period
ending three days before the day the current fair market value of the securities is being determined;

(ii)

if the exercise is in connection with a Merger Event, the fair market value of a share of Common

Stock shall be deemed to be the per share value received by the holders of the outstanding shares of Common Stock pursuant
to such Merger Event as determined in accordance with the definitive transaction documents executed among the parties in
connection therewith; or

(iii)

in cases other than as described in the foregoing clauses (i) and (ii), the current fair market value of

a share of Common Stock shall be determined in good faith by the Company’s Board of Directors.

Upon partial exercise by either cash or Net Issuance, prior to the expiration or earlier termination hereof, the 
Company shall promptly issue an amended Agreement representing the remaining number of shares purchasable hereunder.  
All other terms and conditions of such amended Agreement shall be identical to those contained herein, including, but not 
limited to the Effective Date hereof.

(b)

Exercise Prior to Expiration.  To the extent this Warrant is not previously exercised as to all shares of 

Common Stock subject hereto, and if the then-current fair market value of one share of Common Stock is greater than the 
Exercise Price then in effect, or, in the case of a Liquid Sale, where the value per share of Common Stock (as determined as 
of the closing of such Liquid Sale in accordance with the definitive agreements executed by the parties in connection with 
such Merger Event) to be paid to the holders thereof is greater than the Exercise Price then in effect, this Agreement shall be 
deemed automatically exercised on a Net Issuance basis pursuant to Section 3(a) (even if not surrendered) as of immediately 
before its expiration determined in accordance with Section 2.  For purposes of such automatic exercise, the fair market 
value of one share of Common Stock upon such expiration shall be determined pursuant to Section 3(a).  To the extent this 
Warrant or any portion hereof is deemed automatically exercised pursuant to this Section 3(b), the Company agrees to 
promptly notify the Warrantholder of the number of shares of Common Stock if any, the Warrantholder is to receive by 
reason of such automatic exercise, and to issue or cause its transfer agent to issue a certificate or a book-entry credit to the 
Warrantholder evidencing such shares.

SECTION 4. RESERVATION OF SHARES.

During the term of this Agreement, the Company will at all times have authorized and reserved a sufficient 
number of shares of its Common Stock to provide for the exercise of the rights to purchase Common Stock as provided for 
herein.  If at any time during the term hereof the number of authorized but unissued shares of Common Stock shall not be 
sufficient to permit exercise of this Warrant in full, the Company will take such corporate action

4

as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purposes.

SECTION 5. NO FRACTIONAL SHARES OR SCRIP.

No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this

Agreement, but in lieu of such fractional shares the Company shall make a cash payment therefor in an amount equal to the
product of (a) the Exercise Price then in effect multiplied by (b) the fraction of a share.

SECTION 6. NO RIGHTS AS SHAREHOLDER/STOCKHOLDER.

Without limitation of any provision hereof, the Warrantholder agrees that this Agreement does not entitle the

Warrantholder to any voting rights or other rights as a shareholder/stockholder of the Company prior to the exercise of any
of the purchase rights set forth in this Agreement.

SECTION 7. WARRANTHOLDER REGISTRY.

The Company shall maintain a registry showing the name and address of the registered holder of this 
Agreement.  The Warrantholder’s initial address, for purposes of such registry, is set forth in Section 12(g) below.  The
Warrantholder may change such address by giving written notice of such changed address to the Company.

SECTION 8. ADJUSTMENT RIGHTS.

The Exercise Price and the number of shares of Common Stock purchasable hereunder are subject to

adjustment from time to time, as follows:

(a)

Merger Event.  In connection with a Merger Event that is a Liquid Sale, this Warrant shall, on and 

after the closing thereof, automatically and without further action on the part of any party or other person, represent the right 
to receive the consideration payable on or in respect of all shares of Common Stock that are issuable hereunder as of
immediately prior to the closing of such Merger Event less the Purchase Price for all such shares of Common Stock (such
consideration to include both the consideration payable at the closing of such Merger Event and all deferred consideration
payable thereafter, if any, including, but not limited to, payments of amounts deposited at such closing into escrow and
payments in the nature of earn-outs, milestone payments or other performance-based payments), and such Merger Event
consideration shall be paid to the Warrantholder as and when it is paid to the holders of the outstanding shares of Common 
Stock.  In connection with a Merger Event that is not a Liquid Sale, the Company shall cause the successor or surviving
entity to assume this Warrant and the obligations of the Company hereunder on the closing thereof, and thereafter this
Warrant shall be exercisable for the same number and type of securities or other property as the Warrantholder would have
received in consideration for the shares of Common Stock issuable hereunder had it exercised this Warrant in full as of 
immediately prior to such closing, at an aggregate Exercise Price no greater than the aggregate Exercise Price in effect as of 
immediately prior to such closing, and subject to further adjustment from time to time in accordance with the provisions of 
this Warrant.  The provisions of this Section 8(a) shall similarly apply to successive Merger Events.

(b)

Reclassification of Shares.  Except for Merger Events subject to Section 8(a), if the Company at any 

time shall, by combination, reclassification, exchange or subdivision of securities or otherwise, change any of the securities 
as to which purchase rights under this Agreement exist into the same or a different number of securities of any other class or 
classes of

5

securities, this Agreement shall thereafter represent the right to acquire such number and kind of securities as would have 
been issuable as the result of such change with respect to the securities which were subject to the purchase rights under this 
Agreement immediately prior to such combination, reclassification, exchange, subdivision or other change.  The provisions 
of this Section 8(b) shall similarly apply to successive combination, reclassification, exchange, subdivision or other change.

(c)

Subdivision or Combination of Shares.  If the Company at any time shall combine or subdivide its 

Common Stock, (i) in the case of a subdivision, the Exercise Price shall be proportionately decreased and the number of 
shares for which this Warrant is exercisable shall be proportionately increased, or (ii) in the case of a combination, the 
Exercise Price shall be proportionately increased and the number of shares for which this Warrant is exercisable shall be 
proportionately decreased.

(d)

Dividends.  If the Company at any time while this Agreement is outstanding and unexpired shall:

(i)

pay a dividend with respect to the Common Stock payable in additional shares of Common
Stock, then the Exercise Price shall be adjusted, from and after the date of determination of stockholders entitled to receive
such dividend, to that price determined by multiplying the Exercise Price in effect immediately prior to such date of
determination by a fraction (A) the numerator of which shall be the total number of shares of Common Stock outstanding
immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of
Common Stock outstanding immediately after such dividend or distribution, and the number of shares of Common Stock for
which this Warrant is exercisable shall be proportionately increased; or

(ii)

make any other dividend or distribution on or with respect to Common Stock, except any

dividend or distribution specifically provided for in any other clause of this Section 8, then, in each such case, provision
shall be made by the Company such that the Warrantholder shall receive upon exercise or conversion of this Warrant a
proportionate share of any such dividend or distribution as though it were the holder of the Common Stock (or other stock
for which the Common Stock is convertible) as of the record date fixed for the determination of the stockholders of the
Company entitled to receive such dividend or distribution.

(e)

Notice of Certain Events.  If: (i) the Company shall declare any dividend or distribution upon its 

outstanding Common Stock, payable in stock, cash, property or other securities (provided that the Warrantholder in its 
capacity as lender under the Loan Agreement consents to such dividend); (ii) the Company shall offer for subscription pro 
rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (iii) there shall be any 
Merger Event; or (iv) there shall be any voluntary dissolution, liquidation or winding up of the Company; then, in 
connection with each such event, the Company shall give the Warrantholder notice thereof at the same time and in the same 
manner as it gives notice thereof to the holders of outstanding Common Stock.  In addition, if at any time the number of 
shares of Common Stock (or other securities of any other class or classes of securities of the Company for which this 
Warrant is then exercisable) outstanding is reduced such that the number of shares of Common Stock or other securities 
issuable upon exercise of this Warrant shall exceed five percent (5%) of the then outstanding class of such securities, then, 
within three (3) business days of such event, the Company shall give the Warrantholder written notice thereof.

6

SECTION 9. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

(a) Reservation of Common Stock.  The Company covenants and agrees that all shares of Common Stock  that may 
be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, 
fully paid and non-assessable, and will be free of any taxes, liens, charges or encumbrances of any nature whatsoever; 
provided, that the Common Stock issuable pursuant to this Agreement may be subject to restrictions on transfer under state 
and/or federal securities laws.  The Company has made available to the Warrantholder true, correct and complete copies of 
its Charter and bylaws currently in effect.  The issuance of certificates or book-entry credit for shares of Common Stock 
upon exercise of this Warrant shall be made without charge to the Warrantholder for any issuance tax in respect thereof, or 
other cost incurred by the Company in connection with such exercise and related issuance of shares of Common Stock.  The 
Company further covenants and agrees that the Company will, at all times during the term hereof, have authorized and 
reserved, free from preemptive rights, a sufficient number of shares of Common Stock to provide for the exercise of the 
rights represented by this Warrant.

(b) Due Authority.  The execution and delivery by the Company of this Agreement and the performance of all 
obligations of the Company hereunder, including the issuance to the Warrantholder of the right to acquire the shares of 
Common Stock, have been duly authorized by all necessary corporate action on the part of the Company.  This Agreement: 
(i) does not violate the Charter or the Company’s current bylaws; (ii) does not contravene any law or governmental rule, 
regulation or order applicable to the Company; and (iii) except as could not reasonably be expected to have a Material 
Adverse Effect (as defined in the Loan Agreement), does not and will not contravene any provision of, or constitute a default 
under, any indenture, mortgage, contract or other instrument to which the Company is a party or by which it is bound.  This 
Agreement constitutes a legal, valid and binding agreement of the Company, enforceable in accordance with its terms, 
except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting 
creditors’ rights generally (including, without limitation, fraudulent conveyance laws) and by general principles of equity, 
regardless of whether considered in a proceeding in equity or at law.

(c) Consents and Approvals.  No consent or approval of, giving of notice to, registration with, or taking of any other 

action in respect of any state, federal or other governmental authority or agency is required with respect to the execution, 
delivery and performance by the Company of its obligations under this Agreement, except for the filing of notices pursuant 
to Regulation D under the Act and any filing required by applicable state securities law, which filings will be effective by the 
time required thereby.

(d)  Exempt Transaction.  Subject to the accuracy of the Warrantholder’s representations in Section 10, the issuance 

of the Common Stock upon exercise of this Agreement will constitute a transaction exempt from (i) the registration 
requirements of Section 5 of the Act, in reliance upon Section 4(a)(2) thereof, and (ii) the qualification requirements of the 
applicable state securities laws.

(e) Information Rights.  At all times (if any) prior to the earlier to occur of (x) the date on which all shares of 
Common Stock issued on exercise of this Warrant have been sold, or (y) the expiration or earlier termination of this Warrant, 
when the Company shall not be required to file reports pursuant to Section 13 or 15(d) of the Exchange Act or shall not have 
timely filed all such required reports, the Warrantholder shall be entitled to the information rights contained in Section 7.1(b) 
– (f) of the Loan Agreement, and in any such event Section 7.1(b) – (f) of the Loan

7

Agreement is hereby incorporated into this Agreement by this reference as though fully set forth herein, provided, however,
that the Company shall not be required to deliver a Compliance Certificate once all Indebtedness (as defined in the Loan
Agreement) owed by the Company and its Subsidiaries to Warrantholder has been repaid.

(f) Registration of Shares.  If the Company proposes to register (including, for this purpose, a registration effected 

by the Company for the sale by the Company of its securities and/or the resale of securities of the Company by security 
holders other than the Warrantholder) the sale or resale of any of its Common Shares or other securities under the Act in 
connection with the public offering of such securities (other than in an Excluded Registration), the Company shall cause to 
be registered all of the Registrable Securities in such registration. The Company shall have the right to terminate or 
withdraw any registration initiated by it under this Section 9(f) before the effective date of such registration, provided that
the Company’s obligations to register the Registrable Securities under this Section 9(f) in any subsequent registration (other
than in an Excluded Registration) shall continue following any such termination or withdrawal. All fees and expenses
incident to the Company’s performance of or compliance with its obligations under this Section 9(f) (excluding any
underwriting discounts and selling commissions) shall be borne by the Company.

(g) Rule 144 Compliance.  The Company shall, at all times prior to the earlier to occur of (i) the date of sale or other 

disposition by Warrantholder of this Warrant or all shares of Common Stock issued on exercise of this Warrant,  (ii) the 
registration pursuant to subsection (f) above of the shares issued on exercise of this Warrant, or (iii) the expiration or earlier 
termination of this Warrant if the Warrant has not been exercised in full or in part on such date, use all commercially 
reasonable efforts to timely file all reports required under the Exchange Act and otherwise timely take all actions necessary 
to permit the Warrantholder to sell or otherwise dispose of this Warrant and the shares of Common Stock issued on exercise 
hereof pursuant to Rule 144 promulgated under the Act (“Rule 144”), provided that the foregoing shall not apply in the event 
of a Merger Event following which the successor or surviving entity is not subject to the reporting requirements of the 
Exchange Act.  If the Warrantholder proposes to sell Common Stock issuable upon the exercise of this Agreement in 
compliance with Rule 144, then, upon the Warrantholder’s written request to the Company, the Company shall furnish to the 
Warrantholder, within five (5) business days after receipt of such request, a written statement confirming the Company’s 
compliance with the filing and other requirements of such Rule 144.

covenants of the Warrantholder:

transactions in the Common Stock.

SECTION 11. TRANSFERS.

and all other persons dealing with this Agreement as the absolute owner hereof for any purpose and as the person entitled to 
exercise the rights represented by this Agreement.  The transfer of this Agreement shall be recorded on the books of the 
Company upon receipt by the Company of a notice of transfer in the form attached hereto as Exhibit III (the “Transfer
Notice”), at its principal offices and the payment to the Company of all transfer taxes and other governmental charges 
imposed on such transfer.  Until the Company receives such Transfer Notice, the Company may treat the registered owner 
hereof as the owner for all purposes.  Notwithstanding anything herein or in any legend to the contrary, the Company shall 
not require an opinion of counsel in connection with any sale, assignment or other transfer by the Warrantholder of this 
Warrant (or any portion hereof or any interest herein) or of any shares of Common Stock issued upon any exercise hereof to 
an affiliate (as defined in Regulation D) of the Warrantholder, provided that such affiliate is an “accredited investor” as 
defined in Regulation D.

SECTION 12. MISCELLANEOUS.

(a) Effective Date.  The provisions of this Agreement shall be construed and shall be given effect in all respects as if 

it had been executed and delivered by the Company on the date hereof.  This Agreement shall be binding upon any 
successors or assigns of the Company.

(b) Remedies.  In the event of any default hereunder, the non-defaulting party may proceed to protect and enforce its 

rights either by suit in equity and/or by action at law, including but not limited to an action for damages as a result of any 
such default, and/or an action for specific performance for any default where the Warrantholder will not have an adequate 
remedy at law and where damages will not be readily ascertainable.

(c) No Impairment of Rights.  The Company will not, by amendment of its Charter or through any other means, 
avoid or seek to avoid the observance or performance of any of the terms of this Agreement, but will at all times in good 
faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate in 
order to protect the rights of the Warrantholder against impairment.

9

(d) Additional Documents.  The Company agrees to supply such other documents as the Warrantholder may from

unenforceable provision shall be replaced by a mutually acceptable valid, legal and enforceable provision, which comes

or to such other address as each party may designate for itself by like notice.

(h) Entire Agreement; Amendments.  This Agreement constitutes the entire agreement and understanding of the 

parties hereto in respect of the subject matter hereof, and supersedes and replaces in their entirety any prior proposals, term 
sheets, letters, negotiations or other documents or agreements, whether written or oral, with respect to the subject matter 
hereof.  None of the terms of this Agreement may be amended except by an instrument executed by each of the parties 
hereto.

(i) Headings.  The various headings in this Agreement are inserted for convenience only and shall not affect the 

meaning or interpretation of this Agreement or any provisions hereof.

(j) Advice of Counsel.  Each of the parties represents to each other party hereto that it has discussed (or had an 

opportunity to discuss) with its counsel this Agreement and, specifically, the provisions of Sections 12(n), 12(o), 12(p), 12(q) 
and 12(r).

(k) No Strict Construction.  The parties hereto have participated jointly in the negotiation and drafting of this 

Agreement.  In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if 
drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by 
virtue of the authorship of any provisions of this Agreement.

(l) No Waiver.  No omission or delay by the Warrantholder at any time to enforce any right or remedy reserved to 

it, or to require performance of any of the terms, covenants or provisions hereof by the Company at any time designated, 
shall be a waiver of any such right or remedy to which the Warrantholder is entitled, nor shall it in any way affect the right of 
the Warrantholder to enforce such provisions thereafter during the term of this Agreement.

(m) Survival.  All agreements, representations and warranties contained in this Agreement or in any document 

delivered pursuant hereto shall be for the benefit of the Warrantholder and shall survive the execution and delivery of this 
Agreement and the expiration or other termination of this Agreement.

(n) Governing Law.  This Agreement has been negotiated and delivered to the Warrantholder in the State of 
California, and shall be deemed to have been accepted by the Warrantholder in the State of California.  Delivery of Common 
Stock to the Warrantholder by the Company under this Agreement is due in the State of California.  This Agreement shall be

11

governed by, and construed and enforced in accordance with, the laws of the State of California, excluding conflict of laws
principles that would cause the application of laws of any other jurisdiction.

(o) Consent to Jurisdiction and Venue.  All judicial proceedings arising in or under or related to this Agreement may 

be brought in any state or federal court of competent jurisdiction located in the State of California.  By execution and 
delivery of this Agreement, each party hereto generally and unconditionally: (i) consents to personal jurisdiction in Santa 
Clara County, State of California; (ii) waives any objection as to jurisdiction or venue in Santa Clara County, State of 
California; (iii) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (iv) 
irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement.  Service of process on 
any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance with the 
requirements for notice set forth in Section 12(g), and shall be deemed effective and received as set forth in Section 12(g).  
Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either 
party to bring proceedings in the courts of any other jurisdiction.

(p) Mutual Waiver of Jury Trial.  Because disputes arising in connection with complex financial transactions are 

most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and 
federal laws to apply (rather than arbitration rules), the parties desire that their disputes arising under or in connection with 
this Warrant be resolved by a judge applying such applicable laws.  EACH OF THE COMPANY AND THE 
WARRANTHOLDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE 
OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM 
(COLLECTIVELY, “CLAIMS”) ASSERTED BY THE COMPANY AGAINST THE WARRANTHOLDER OR ITS 
ASSIGNEE OR BY THE WARRANTHOLDER OR ITS ASSIGNEE AGAINST THE COMPANY RELATING TO THIS 
WARRANT.  This waiver extends to all such Claims, including Claims that involve persons or entities other the Company 
and the Warrantholder; Claims that arise out of or are in any way connected to the relationship between the Company and 
the Warrantholder; and any Claims for damages, breach of contract, specific performance, or any equitable or legal relief of 
any kind, arising out of this Agreement.

(q) Arbitration.  If the Mutual Waiver of Jury Trial set forth in Section 12(p) is ineffective or unenforceable, the 

parties agree that all Claims shall be submitted to binding arbitration in accordance with the commercial arbitration rules of 
JAMS (the “Rules”), such arbitration to occur before one arbitrator, which arbitrator shall be a retired California state judge 
or a retired Federal court judge.  Such proceeding shall be conducted in Santa Clara County, State of California, with 
California rules of evidence and discovery applicable to such arbitration.  The decision of the arbitrator shall be binding on 
the parties, and shall be final and nonappealable to the maximum extent permitted by law.  Any judgment rendered by the 
arbitrator may be entered in a court of competent jurisdiction and enforced by the prevailing party as a final judgment of 
such court.

(r) Pre-arbitration Relief.  In the event Claims are to be resolved by arbitration, either party may seek from a court 
of competent jurisdiction identified in Section 12(o), any prejudgment order, writ or other relief and have such prejudgment 
order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise 
subject to resolution by binding arbitration.

(s) Counterparts.  This Agreement and any amendments, waivers, consents or supplements hereto may be executed 

in any number of counterparts (including by facsimile or

12

electronic delivery (PDF)), and by different parties hereto in separate counterparts, each of which when so delivered shall be
deemed an original, but all of which counterparts shall constitute but one and the same instrument.

(t) Specific Performance.  The parties hereto hereby declare that it is impossible to measure in money the damages 

which will accrue to the Warrantholder by reason of the Company’s failure to perform any of the obligations under this 
Agreement and agree that the terms of this Agreement shall be specifically enforceable by the Warrantholder.  If the 
Warrantholder institutes any action or proceeding to specifically enforce the provisions hereof, any person against whom 
such action or proceeding is brought hereby waives the claim or defense therein that the Warrantholder has an adequate 
remedy at law, and such person shall not offer in any such action or proceeding the claim or defense that such remedy at law 
exists.

(u) Lost, Stolen, Mutilated or Destroyed Warrant.  If this Warrant is lost, stolen, mutilated or destroyed, the 
Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a 
mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as this Warrant so lost, 
stolen, mutilated or destroyed.  Any such new Warrant shall constitute an original contractual obligation of the Company, 
whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

(v) Legends.  To the extent required by applicable laws, this Warrant and the shares of Common Stock issuable 

hereunder (and the securities issuable, directly or indirectly, upon conversion of such shares of Common Stock, if any) may 
be imprinted with a restricted securities legend in substantially the following form:

Exhibit 10.30

WARRANT AGREEMENT

To Purchase Shares of the Common Stock of

TG THERAPEUTICS, INC.

Dated as of December 30, 2021 (the “Effective Date”)

WHEREAS, TG Therapeutics, Inc., a Delaware corporation (the “Company”), has entered into an Amended and

Restated Loan and Security Agreement of even date herewith (as amended and in effect from time to time, the “Loan
Agreement”) with Hercules Capital, Inc., a Maryland corporation, in its capacity as administrative and collateral agent,
Hercules Private Credit Fund I L.P., as a lender (the “Warrantholder”), and the other lenders from time to time party thereto;

WHEREAS, pursuant to the Loan Agreement and as additional consideration to the Warrantholder for,
among other things, its agreements in the Loan Agreement, the Company has agreed to issue to the Warrantholder this
Warrant Agreement, evidencing the right to purchase shares of the Company’s Common Stock (this “Warrant”, “Warrant
Agreement”, or this “Agreement”);

NOW, THEREFORE, in consideration of the Warrantholder having executed and delivered the Loan

Agreement and provided the financial accommodations contemplated therein, and in consideration of the mutual covenants
and agreements contained herein, the Company and Warrantholder agree as follows:

SECTION 1. GRANT OF THE RIGHT TO PURCHASE COMMON STOCK.

(a)

For value received, the Company hereby grants to the Warrantholder, and the Warrantholder is

entitled, upon the terms and subject to the conditions hereinafter set forth, to subscribe for and purchase, from the Company,
up to the aggregate number of fully paid and non-assessable shares of Common Stock (as defined below) as determined 
pursuant to Section 1(b) below, at a purchase price per share equal to the Exercise Price (as defined below).  The number and 
Exercise Price of such shares are subject to adjustment as provided in Section 8.  As used herein, the following terms shall 
have the following meanings:

“Act” means the Securities Act of 1933, as amended.

“Charter” means the Company’s Certificate of Incorporation or other constitutional document, as may be

amended and in effect from time to time.

“Common Stock” means the Company’s common stock, $0.001 par value per share, as presently constituted

under the Charter, and any class and/or series of Company capital stock for or into which such common stock may
be converted or exchanged in a reorganization, recapitalization or similar transaction.

“Excluded Registration” means (i) a registration relating to the sale of securities to employees of the
Company or a subsidiary pursuant to an equity option, equity purchase, or similar plan; (ii) a registration relating to
an SEC Rule 145 transaction; or (iii) a registration on any form that does not include substantially the same
information as would be required to be included in a registration statement covering the sale of the Registrable
Securities, provided that, for the avoidance of doubt, the inclusion of information regarding this Warrant and the
plan of distribution of and selling securityholder information related to the Common Shares issuable upon exercise
of this Warrant, shall not constitute a basis for excluding the Registrable Securities from a registration pursuant to
this clause (iii).

“Exercise Price”  means $17.95, subject to adjustment from time to time in accordance with the provisions

of this Warrant.

“Liquid Sale” means the closing of a Merger Event in which the consideration received by the Company

and/or its stockholders, as applicable, consists solely of cash and/or Marketable Securities.

“Marketable Securities” in connection with a Merger Event means securities meeting all of the following

requirements: (i) the issuer thereof is then subject to the reporting requirements of Section 13 or Section 15(d) of the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is then current in its filing of all required
reports and other information under the Act and the Exchange Act; (ii) the class and series of shares or other security
of the issuer that would be received by the Warrantholder in connection with the Merger Event were the
Warrantholder to exercise this Warrant on or prior to the closing thereof is then traded on a national securities
exchange or over-the-counter market, and (iii) following the closing of such Merger Event, the Warrantholder would
not be restricted from publicly re-selling all of the issuer’s shares and/or other securities that would be received by
the Warrantholder in such Merger Event were the Warrantholder to exercise this Warrant in full on or prior to the
closing of such Merger Event, except to the extent that any such restriction (x) arises solely under federal or state
securities laws, rules or regulations, and (y) does not extend beyond six (6) months from the closing of such Merger
Event.

“Merger Event” means any of the following: (i) a sale, lease or other transfer of all or substantially all assets
of the Company, (ii) any merger or consolidation involving the Company in which the Company is not the surviving
entity or in which the outstanding shares of the Company’s capital stock are otherwise converted into or exchanged
for shares of capital stock or other securities or property of another entity, or (iii) any sale by holders of the
outstanding voting equity securities of the Company in a single transaction or series of related transactions of shares
constituting a majority of the outstanding combined voting power of the Company.

“Purchase Price” means, with respect to any exercise of this Warrant, an amount equal to the then-effective

Exercise Price multiplied by the number of shares of Common Stock as to which this Warrant is then exercised.

2

“Registrable Securities” means (i) the shares issuable upon exercise of this Warrant and (ii) any other
Common Shares issued as a dividend or other distribution with respect to, in exchange for or in replacement of such
shares; provided that the securities referred to in (i)-(ii) above shall cease to be Registrable Securities (A) upon the
sale of such securities pursuant to a registration statement or (B) upon the sale of such securities pursuant to Rule
144.

“Warrant Coverage” means 2.95% times the aggregate principal amount of Term Loan Advances (as defined

in the Loan Agreement) made and funded by the Warrantholder under the Loan Agreement from time to time.

(b)

Number of Shares.

This Warrant shall be exercisable for a number of shares of Common Stock equal to
the quotient derived by dividing (i) the Warrant Coverage by (ii) the Exercise Price, subject to adjustment from time to time
in accordance with the provisions of this Warrant.

SECTION 2. TERM OF THE AGREEMENT.

The term of this Agreement and the right to purchase Common Stock as granted herein shall commence on

the Effective Date and, subject to Section 8(a) below, shall be exercisable until 5:00 p.m. (Eastern Time) on the seventh (7th)
anniversary of the Effective Date.

SECTION 3. EXERCISE OF THE PURCHASE RIGHTS.

(a)

Exercise.  The purchase rights set forth in this Agreement are exercisable by the Warrantholder, in whole or 

in part, at any time, or from time to time, prior to the expiration of the term set forth in Section 2, by tendering to the 
Company at its principal office a notice of exercise in the form attached hereto as Exhibit I (the “Notice of Exercise”), duly 
completed and executed.  Promptly upon receipt of the Notice of Exercise and the payment of the Purchase Price in 
accordance with the terms set forth below, and in no event later than three (3) business days thereafter, the Company or its 
transfer agent shall either (i) issue to the Warrantholder a certificate for the number of shares of Common Stock purchased or 
(ii) credit the same via book entry to the Warrantholder, and the Company shall execute the acknowledgment of exercise in 
the form attached hereto as Exhibit II (the “Acknowledgment of Exercise”) indicating the number of shares which remain
subject to future purchases under this Warrant, if any.

The Purchase Price may be paid at the Warrantholder’s election either (i) by cash or check, or (ii) by
surrender of all or a portion of the Warrant for shares of Common Stock to be exercised under this Agreement and, if
applicable, an amended Agreement setting forth the remaining number of shares purchasable hereunder, as determined
below (“Net Issuance”).  If the Warrantholder elects the Net Issuance method, the Company will issue shares of Common 
Stock in accordance with the following formula:

X = Y(A-B)
            A

Where:

X = 

Y = 

the number of shares of Common Stock to be issued to the Warrantholder.

the number of shares of Common Stock requested to be exercised under this Agreement.

3

the then-current fair market value of one (1) share of Common Stock at the time of exercise of this

A = 
Warrant.

B = 

the then-effective Exercise Price.

For purposes of the above calculation, the current fair market value of shares of Common Stock shall mean with

respect to each share of Common Stock:

(i)

at all times when the Common Stock is traded on a national securities exchange, inter-dealer

quotation system or over-the-counter bulletin board service, the average of the closing prices over a five (5) day period
ending three days before the day the current fair market value of the securities is being determined;

(ii)

if the exercise is in connection with a Merger Event, the fair market value of a share of Common

Stock shall be deemed to be the per share value received by the holders of the outstanding shares of Common Stock pursuant
to such Merger Event as determined in accordance with the definitive transaction documents executed among the parties in
connection therewith; or

(iii)

in cases other than as described in the foregoing clauses (i) and (ii), the current fair market value of

a share of Common Stock shall be determined in good faith by the Company’s Board of Directors.

Upon partial exercise by either cash or Net Issuance, prior to the expiration or earlier termination hereof, the 
Company shall promptly issue an amended Agreement representing the remaining number of shares purchasable hereunder.  
All other terms and conditions of such amended Agreement shall be identical to those contained herein, including, but not 
limited to the Effective Date hereof.

(b)

Exercise Prior to Expiration.  To the extent this Warrant is not previously exercised as to all shares of 

Common Stock subject hereto, and if the then-current fair market value of one share of Common Stock is greater than the 
Exercise Price then in effect, or, in the case of a Liquid Sale, where the value per share of Common Stock (as determined as 
of the closing of such Liquid Sale in accordance with the definitive agreements executed by the parties in connection with 
such Merger Event) to be paid to the holders thereof is greater than the Exercise Price then in effect, this Agreement shall be 
deemed automatically exercised on a Net Issuance basis pursuant to Section 3(a) (even if not surrendered) as of immediately 
before its expiration determined in accordance with Section 2.  For purposes of such automatic exercise, the fair market 
value of one share of Common Stock upon such expiration shall be determined pursuant to Section 3(a).  To the extent this 
Warrant or any portion hereof is deemed automatically exercised pursuant to this Section 3(b), the Company agrees to 
promptly notify the Warrantholder of the number of shares of Common Stock if any, the Warrantholder is to receive by 
reason of such automatic exercise, and to issue or cause its transfer agent to issue a certificate or a book-entry credit to the 
Warrantholder evidencing such shares.

SECTION 4. RESERVATION OF SHARES.

During the term of this Agreement, the Company will at all times have authorized and reserved a sufficient 
number of shares of its Common Stock to provide for the exercise of the rights to purchase Common Stock as provided for 
herein.  If at any time during the term hereof the number of authorized but unissued shares of Common Stock shall not be 
sufficient to permit exercise of this Warrant in full, the Company will take such corporate action

4

as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purposes.

SECTION 5. NO FRACTIONAL SHARES OR SCRIP.

No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this

Agreement, but in lieu of such fractional shares the Company shall make a cash payment therefor in an amount equal to the
product of (a) the Exercise Price then in effect multiplied by (b) the fraction of a share.

SECTION 6. NO RIGHTS AS SHAREHOLDER/STOCKHOLDER.

Without limitation of any provision hereof, the Warrantholder agrees that this Agreement does not entitle the

Warrantholder to any voting rights or other rights as a shareholder/stockholder of the Company prior to the exercise of any
of the purchase rights set forth in this Agreement.

SECTION 7. WARRANTHOLDER REGISTRY.

The Company shall maintain a registry showing the name and address of the registered holder of this 
Agreement.  The Warrantholder’s initial address, for purposes of such registry, is set forth in Section 12(g) below.  The
Warrantholder may change such address by giving written notice of such changed address to the Company.

SECTION 8. ADJUSTMENT RIGHTS.

The Exercise Price and the number of shares of Common Stock purchasable hereunder are subject to

adjustment from time to time, as follows:

(a)

Merger Event.  In connection with a Merger Event that is a Liquid Sale, this Warrant shall, on and 

after the closing thereof, automatically and without further action on the part of any party or other person, represent the right 
to receive the consideration payable on or in respect of all shares of Common Stock that are issuable hereunder as of
immediately prior to the closing of such Merger Event less the Purchase Price for all such shares of Common Stock (such
consideration to include both the consideration payable at the closing of such Merger Event and all deferred consideration
payable thereafter, if any, including, but not limited to, payments of amounts deposited at such closing into escrow and
payments in the nature of earn-outs, milestone payments or other performance-based payments), and such Merger Event
consideration shall be paid to the Warrantholder as and when it is paid to the holders of the outstanding shares of Common 
Stock.  In connection with a Merger Event that is not a Liquid Sale, the Company shall cause the successor or surviving
entity to assume this Warrant and the obligations of the Company hereunder on the closing thereof, and thereafter this
Warrant shall be exercisable for the same number and type of securities or other property as the Warrantholder would have
received in consideration for the shares of Common Stock issuable hereunder had it exercised this Warrant in full as of 
immediately prior to such closing, at an aggregate Exercise Price no greater than the aggregate Exercise Price in effect as of 
immediately prior to such closing, and subject to further adjustment from time to time in accordance with the provisions of 
this Warrant.  The provisions of this Section 8(a) shall similarly apply to successive Merger Events.

(b)

Reclassification of Shares.  Except for Merger Events subject to Section 8(a), if the Company at any 

time shall, by combination, reclassification, exchange or subdivision of securities or otherwise, change any of the securities 
as to which purchase rights under this Agreement exist into the same or a different number of securities of any other class or 
classes of

5

securities, this Agreement shall thereafter represent the right to acquire such number and kind of securities as would have 
been issuable as the result of such change with respect to the securities which were subject to the purchase rights under this 
Agreement immediately prior to such combination, reclassification, exchange, subdivision or other change.  The provisions 
of this Section 8(b) shall similarly apply to successive combination, reclassification, exchange, subdivision or other change.

(c)

Subdivision or Combination of Shares.  If the Company at any time shall combine or subdivide its 

Common Stock, (i) in the case of a subdivision, the Exercise Price shall be proportionately decreased and the number of 
shares for which this Warrant is exercisable shall be proportionately increased, or (ii) in the case of a combination, the 
Exercise Price shall be proportionately increased and the number of shares for which this Warrant is exercisable shall be 
proportionately decreased.

(d)

Dividends.  If the Company at any time while this Agreement is outstanding and unexpired shall:

(i)

pay a dividend with respect to the Common Stock payable in additional shares of Common
Stock, then the Exercise Price shall be adjusted, from and after the date of determination of stockholders entitled to receive
such dividend, to that price determined by multiplying the Exercise Price in effect immediately prior to such date of
determination by a fraction (A) the numerator of which shall be the total number of shares of Common Stock outstanding
immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of
Common Stock outstanding immediately after such dividend or distribution, and the number of shares of Common Stock for
which this Warrant is exercisable shall be proportionately increased; or

(ii)

make any other dividend or distribution on or with respect to Common Stock, except any

dividend or distribution specifically provided for in any other clause of this Section 8, then, in each such case, provision
shall be made by the Company such that the Warrantholder shall receive upon exercise or conversion of this Warrant a
proportionate share of any such dividend or distribution as though it were the holder of the Common Stock (or other stock
for which the Common Stock is convertible) as of the record date fixed for the determination of the stockholders of the
Company entitled to receive such dividend or distribution.

(e)

Notice of Certain Events.  If: (i) the Company shall declare any dividend or distribution upon its 

outstanding Common Stock, payable in stock, cash, property or other securities (provided that the Warrantholder in its 
capacity as lender under the Loan Agreement consents to such dividend); (ii) the Company shall offer for subscription pro 
rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (iii) there shall be any 
Merger Event; or (iv) there shall be any voluntary dissolution, liquidation or winding up of the Company; then, in 
connection with each such event, the Company shall give the Warrantholder notice thereof at the same time and in the same 
manner as it gives notice thereof to the holders of outstanding Common Stock.  In addition, if at any time the number of 
shares of Common Stock (or other securities of any other class or classes of securities of the Company for which this 
Warrant is then exercisable) outstanding is reduced such that the number of shares of Common Stock or other securities 
issuable upon exercise of this Warrant shall exceed five percent (5%) of the then outstanding class of such securities, then, 
within three (3) business days of such event, the Company shall give the Warrantholder written notice thereof.

6

SECTION 9. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

(a) Reservation of Common Stock.  The Company covenants and agrees that all shares of Common Stock  that may 
be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, 
fully paid and non-assessable, and will be free of any taxes, liens, charges or encumbrances of any nature whatsoever; 
provided, that the Common Stock issuable pursuant to this Agreement may be subject to restrictions on transfer under state 
and/or federal securities laws.  The Company has made available to the Warrantholder true, correct and complete copies of 
its Charter and bylaws currently in effect.  The issuance of certificates or book-entry credit for shares of Common Stock 
upon exercise of this Warrant shall be made without charge to the Warrantholder for any issuance tax in respect thereof, or 
other cost incurred by the Company in connection with such exercise and related issuance of shares of Common Stock.  The 
Company further covenants and agrees that the Company will, at all times during the term hereof, have authorized and 
reserved, free from preemptive rights, a sufficient number of shares of Common Stock to provide for the exercise of the 
rights represented by this Warrant.

(b) Due Authority.  The execution and delivery by the Company of this Agreement and the performance of all 
obligations of the Company hereunder, including the issuance to the Warrantholder of the right to acquire the shares of

(i) does not violate the Charter or the Company’s current bylaws; (ii) does not contravene any law or governmental rule, 
regulation or order applicable to the Company; and (iii) except as could not reasonably be expected to have a Material 
Adverse Effect (as defined in the Loan Agreement), does not and will not contravene any provision of, or constitute a default 
under, any indenture, mortgage, contract or other instrument to which the Company is a party or by which it is bound.  This 
Agreement constitutes a legal, valid and binding agreement of the Company, enforceable in accordance with its terms, 
except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting 
creditors’ rights generally (including, without limitation, fraudulent conveyance laws) and by general principles of equity, 
regardless of whether considered in a proceeding in equity or at law.

(c) Consents and Approvals.  No consent or approval of, giving of notice to, registration with, or taking of any other 

action in respect of any state, federal or other governmental authority or agency is required with respect to the execution, 
delivery and performance by the Company of its obligations under this Agreement, except for the filing of notices pursuant 
to Regulation D under the Act and any filing required by applicable state securities law, which filings will be effective by the 
time required thereby.

(d)  Exempt Transaction.  Subject to the accuracy of the Warrantholder’s representations in Section 10, the issuance 

of the Common Stock upon exercise of this Agreement will constitute a transaction exempt from (i) the registration 
requirements of Section 5 of the Act, in reliance upon Section 4(a)(2) thereof, and (ii) the qualification requirements of the 
applicable state securities laws.

(e) Information Rights.  At all times (if any) prior to the earlier to occur of (x) the date on which all shares of 
Common Stock issued on exercise of this Warrant have been sold, or (y) the expiration or earlier termination of this Warrant, 
when the Company shall not be required to file reports pursuant to Section 13 or 15(d) of the Exchange Act or shall not have 
timely filed all such required reports, the Warrantholder shall be entitled to the information rights contained in Section 7.1(b) 
– (f) of the Loan Agreement, and in any such event Section 7.1(b) – (f) of the Loan

7

Agreement is hereby incorporated into this Agreement by this reference as though fully set forth herein, provided, however,
that the Company shall not be required to deliver a Compliance Certificate once all Indebtedness (as defined in the Loan
Agreement) owed by the Company and its Subsidiaries to Warrantholder has been repaid.

(f) Registration of Shares.  If the Company proposes to register (including, for this purpose, a registration effected 

by the Company for the sale by the Company of its securities and/or the resale of securities of the Company by security 
holders other than the Warrantholder) the sale or resale of any of its Common Shares or other securities under the Act in 
connection with the public offering of such securities (other than in an Excluded Registration), the Company shall cause to 
be registered all of the Registrable Securities in such registration. The Company shall have the right to terminate or 
withdraw any registration initiated by it under this Section 9(f) before the effective date of such registration, provided that
the Company’s obligations to register the Registrable Securities under this Section 9(f) in any subsequent registration (other
than in an Excluded Registration) shall continue following any such termination or withdrawal. All fees and expenses
incident to the Company’s performance of or compliance with its obligations under this Section 9(f) (excluding any
underwriting discounts and selling commissions) shall be borne by the Company.

(g) Rule 144 Compliance.  The Company shall, at all times prior to the earlier to occur of (i) the date of sale or other 

disposition by Warrantholder of this Warrant or all shares of Common Stock issued on exercise of this Warrant,  (ii) the 
registration pursuant to subsection (f) above of the shares issued on exercise of this Warrant, or (iii) the expiration or earlier 
termination of this Warrant if the Warrant has not been exercised in full or in part on such date, use all commercially 
reasonable efforts to timely file all reports required under the Exchange Act and otherwise timely take all actions necessary 
to permit the Warrantholder to sell or otherwise dispose of this Warrant and the shares of Common Stock issued on exercise 
hereof pursuant to Rule 144 promulgated under the Act (“Rule 144”), provided that the foregoing shall not apply in the event 
of a Merger Event following which the successor or surviving entity is not subject to the reporting requirements of the 
Exchange Act.  If the Warrantholder proposes to sell Common Stock issuable upon the exercise of this Agreement in 
compliance with Rule 144, then, upon the Warrantholder’s written request to the Company, the Company shall furnish to the 
Warrantholder, within five (5) business days after receipt of such request, a written statement confirming the Company’s 
compliance with the filing and other requirements of such Rule 144.

remedy at law and where damages will not be readily ascertainable.

avoid or seek to avoid the observance or performance of any of the terms of this Agreement, but will at all times in good 
faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate in

or to such other address as each party may designate for itself by like notice.

(h) Entire Agreement; Amendments.  This Agreement constitutes the entire agreement and understanding of the 

parties hereto in respect of the subject matter hereof, and supersedes and replaces in their entirety any prior proposals, term 
sheets, letters, negotiations or other documents or agreements, whether written or oral, with respect to the subject matter 
hereof.  None of the terms of this Agreement may be amended except by an instrument executed by each of the parties 
hereto.

(i) Headings.  The various headings in this Agreement are inserted for convenience only and shall not affect the 

meaning or interpretation of this Agreement or any provisions hereof.

(j) Advice of Counsel.  Each of the parties represents to each other party hereto that it has discussed (or had an 

opportunity to discuss) with its counsel this Agreement and, specifically, the provisions of Sections 12(n), 12(o), 12(p), 12(q) 
and 12(r).

(k) No Strict Construction.  The parties hereto have participated jointly in the negotiation and drafting of this 

Agreement.  In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if 
drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by 
virtue of the authorship of any provisions of this Agreement.

(l) No Waiver.  No omission or delay by the Warrantholder at any time to enforce any right or remedy reserved to 

it, or to require performance of any of the terms, covenants or provisions hereof by the Company at any time designated, 
shall be a waiver of any such right or remedy to which the Warrantholder is entitled, nor shall it in any way affect the right of 
the Warrantholder to enforce such provisions thereafter during the term of this Agreement.

(m) Survival.  All agreements, representations and warranties contained in this Agreement or in any document 

delivered pursuant hereto shall be for the benefit of the Warrantholder and shall survive the execution and delivery of this 
Agreement and the expiration or other termination of this Agreement.

(n) Governing Law.  This Agreement has been negotiated and delivered to the Warrantholder in the State of 
California, and shall be deemed to have been accepted by the Warrantholder in the State of California.  Delivery of Common 
Stock to the Warrantholder by the Company under this Agreement is due in the State of California.  This Agreement shall be

11

governed by, and construed and enforced in accordance with, the laws of the State of California, excluding conflict of laws
principles that would cause the application of laws of any other jurisdiction.

(o) Consent to Jurisdiction and Venue.  All judicial proceedings arising in or under or related to this Agreement may 

be brought in any state or federal court of competent jurisdiction located in the State of California.  By execution and 
delivery of this Agreement, each party hereto generally and unconditionally: (i) consents to personal jurisdiction in Santa 
Clara County, State of California; (ii) waives any objection as to jurisdiction or venue in Santa Clara County, State of 
California; (iii) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (iv) 
irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement.  Service of process on 
any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance with the 
requirements for notice set forth in Section 12(g), and shall be deemed effective and received as set forth in Section 12(g).  
Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either 
party to bring proceedings in the courts of any other jurisdiction.

(p) Mutual Waiver of Jury Trial.  Because disputes arising in connection with complex financial transactions are 

most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and 
federal laws to apply (rather than arbitration rules), the parties desire that their disputes arising under or in connection with 
this Warrant be resolved by a judge applying such applicable laws.  EACH OF THE COMPANY AND THE 
WARRANTHOLDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE 
OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM 
(COLLECTIVELY, “CLAIMS”) ASSERTED BY THE COMPANY AGAINST THE WARRANTHOLDER OR ITS 
ASSIGNEE OR BY THE WARRANTHOLDER OR ITS ASSIGNEE AGAINST THE COMPANY RELATING TO THIS 
WARRANT.  This waiver extends to all such Claims, including Claims that involve persons or entities other the Company 
and the Warrantholder; Claims that arise out of or are in any way connected to the relationship between the Company and 
the Warrantholder; and any Claims for damages, breach of contract, specific performance, or any equitable or legal relief of 
any kind, arising out of this Agreement.

(q) Arbitration.  If the Mutual Waiver of Jury Trial set forth in Section 12(p) is ineffective or unenforceable, the 

parties agree that all Claims shall be submitted to binding arbitration in accordance with the commercial arbitration rules of 
JAMS (the “Rules”), such arbitration to occur before one arbitrator, which arbitrator shall be a retired California state judge 
or a retired Federal court judge.  Such proceeding shall be conducted in Santa Clara County, State of California, with 
California rules of evidence and discovery applicable to such arbitration.  The decision of the arbitrator shall be binding on 
the parties, and shall be final and nonappealable to the maximum extent permitted by law.  Any judgment rendered by the 
arbitrator may be entered in a court of competent jurisdiction and enforced by the prevailing party as a final judgment of 
such court.

(r) Pre-arbitration Relief.  In the event Claims are to be resolved by arbitration, either party may seek from a court 
of competent jurisdiction identified in Section 12(o), any prejudgment order, writ or other relief and have such prejudgment 
order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise 
subject to resolution by binding arbitration.

(s) Counterparts.  This Agreement and any amendments, waivers, consents or supplements hereto may be executed 

in any number of counterparts (including by facsimile or

12

electronic delivery (PDF)), and by different parties hereto in separate counterparts, each of which when so delivered shall be
deemed an original, but all of which counterparts shall constitute but one and the same instrument.

(t) Specific Performance.  The parties hereto hereby declare that it is impossible to measure in money the damages 

which will accrue to the Warrantholder by reason of the Company’s failure to perform any of the obligations under this 
Agreement and agree that the terms of this Agreement shall be specifically enforceable by the Warrantholder.  If the 
Warrantholder institutes any action or proceeding to specifically enforce the provisions hereof, any person against whom 
such action or proceeding is brought hereby waives the claim or defense therein that the Warrantholder has an adequate 
remedy at law, and such person shall not offer in any such action or proceeding the claim or defense that such remedy at law 
exists.

(u) Lost, Stolen, Mutilated or Destroyed Warrant.  If this Warrant is lost, stolen, mutilated or destroyed, the 
Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a 
mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as this Warrant so lost, 
stolen, mutilated or destroyed.  Any such new Warrant shall constitute an original contractual obligation of the Company, 
whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

(v) Legends.  To the extent required by applicable laws, this Warrant and the shares of Common Stock issuable 

hereunder (and the securities issuable, directly or indirectly, upon conversion of such shares of Common Stock, if any) may 
be imprinted with a restricted securities legend in substantially the following form:

WHEREAS, TG Therapeutics, Inc., a Delaware corporation (the “Company”), has entered into an Amended and

Restated Loan and Security Agreement of even date herewith (as amended and in effect from time to time, the “Loan
Agreement”) with Hercules Capital, Inc., a Maryland corporation, in its capacity as administrative and collateral agent,
Hercules Private Global Venture Growth Fund I L.P., as a lender (the “Warrantholder”), and the other lenders from time to

Securities, provided that, for the avoidance of doubt, the inclusion of information regarding this Warrant and the
plan of distribution of and selling securityholder information related to the Common Shares issuable upon exercise
of this Warrant, shall not constitute a basis for excluding the Registrable Securities from a registration pursuant to
this clause (iii).

“Exercise Price”  means $17.95, subject to adjustment from time to time in accordance with the provisions

of this Warrant.

“Liquid Sale” means the closing of a Merger Event in which the consideration received by the Company

reports and other information under the Act and the Exchange Act; (ii) the class and series of shares or other security
of the issuer that would be received by the Warrantholder in connection with the Merger Event were the
Warrantholder to exercise this Warrant on or prior to the closing thereof is then traded on a national securities

not be restricted from publicly re-selling all of the issuer’s shares and/or other securities that would be received by

Event.

“Merger Event” means any of the following: (i) a sale, lease or other transfer of all or substantially all assets
of the Company, (ii) any merger or consolidation involving the Company in which the Company is not the surviving
entity or in which the outstanding shares of the Company’s capital stock are otherwise converted into or exchanged
for shares of capital stock or other securities or property of another entity, or (iii) any sale by holders of the
outstanding voting equity securities of the Company in a single transaction or series of related transactions of shares
constituting a majority of the outstanding combined voting power of the Company.

“Purchase Price” means, with respect to any exercise of this Warrant, an amount equal to the then-effective

Exercise Price multiplied by the number of shares of Common Stock as to which this Warrant is then exercised.

2

“Registrable Securities” means (i) the shares issuable upon exercise of this Warrant and (ii) any other
Common Shares issued as a dividend or other distribution with respect to, in exchange for or in replacement of such
shares; provided that the securities referred to in (i)-(ii) above shall cease to be Registrable Securities (A) upon the

in accordance with the provisions of this Warrant.

SECTION 2. TERM OF THE AGREEMENT.

The term of this Agreement and the right to purchase Common Stock as granted herein shall commence on

the Effective Date and, subject to Section 8(a) below, shall be exercisable until 5:00 p.m. (Eastern Time) on the seventh (7th)
anniversary of the Effective Date.

SECTION 3. EXERCISE OF THE PURCHASE RIGHTS.

(a)

Exercise.  The purchase rights set forth in this Agreement are exercisable by the Warrantholder, in whole or 

in part, at any time, or from time to time, prior to the expiration of the term set forth in Section 2, by tendering to the 
Company at its principal office a notice of exercise in the form attached hereto as Exhibit I (the “Notice of Exercise”), duly 
completed and executed.  Promptly upon receipt of the Notice of Exercise and the payment of the Purchase Price in 
accordance with the terms set forth below, and in no event later than three (3) business days thereafter, the Company or its 
transfer agent shall either (i) issue to the Warrantholder a certificate for the number of shares of Common Stock purchased or 
(ii) credit the same via book entry to the Warrantholder, and the Company shall execute the acknowledgment of exercise in 
the form attached hereto as Exhibit II (the “Acknowledgment of Exercise”) indicating the number of shares which remain
subject to future purchases under this Warrant, if any.

The Purchase Price may be paid at the Warrantholder’s election either (i) by cash or check, or (ii) by
surrender of all or a portion of the Warrant for shares of Common Stock to be exercised under this Agreement and, if
applicable, an amended Agreement setting forth the remaining number of shares purchasable hereunder, as determined
below (“Net Issuance”).  If the Warrantholder elects the Net Issuance method, the Company will issue shares of Common 
Stock in accordance with the following formula:

X = Y(A-B)
            A

Where:

X = 

Y = 

the number of shares of Common Stock to be issued to the Warrantholder.

the number of shares of Common Stock requested to be exercised under this Agreement.

3

the then-current fair market value of one (1) share of Common Stock at the time of exercise of this

A = 
Warrant.

B = 

the then-effective Exercise Price.

For purposes of the above calculation, the current fair market value of shares of Common Stock shall mean with

respect to each share of Common Stock:

(i)

at all times when the Common Stock is traded on a national securities exchange, inter-dealer

quotation system or over-the-counter bulletin board service, the average of the closing prices over a five (5) day period
ending three days before the day the current fair market value of the securities is being determined;

(ii)

if the exercise is in connection with a Merger Event, the fair market value of a share of Common

Stock shall be deemed to be the per share value received by the holders of the outstanding shares of Common Stock pursuant
to such Merger Event as determined in accordance with the definitive transaction documents executed among the parties in
connection therewith; or

(iii)

in cases other than as described in the foregoing clauses (i) and (ii), the current fair market value of

a share of Common Stock shall be determined in good faith by the Company’s Board of Directors.

Upon partial exercise by either cash or Net Issuance, prior to the expiration or earlier termination hereof, the 
Company shall promptly issue an amended Agreement representing the remaining number of shares purchasable hereunder.  
All other terms and conditions of such amended Agreement shall be identical to those contained herein, including, but not 
limited to the Effective Date hereof.

(b)

Exercise Prior to Expiration.  To the extent this Warrant is not previously exercised as to all shares of 

Common Stock subject hereto, and if the then-current fair market value of one share of Common Stock is greater than the 
Exercise Price then in effect, or, in the case of a Liquid Sale, where the value per share of Common Stock (as determined as 
of the closing of such Liquid Sale in accordance with the definitive agreements executed by the parties in connection with 
such Merger Event) to be paid to the holders thereof is greater than the Exercise Price then in effect, this Agreement shall be 
deemed automatically exercised on a Net Issuance basis pursuant to Section 3(a) (even if not surrendered) as of immediately 
before its expiration determined in accordance with Section 2.  For purposes of such automatic exercise, the fair market 
value of one share of Common Stock upon such expiration shall be determined pursuant to Section 3(a).  To the extent this 
Warrant or any portion hereof is deemed automatically exercised pursuant to this Section 3(b), the Company agrees to 
promptly notify the Warrantholder of the number of shares of Common Stock if any, the Warrantholder is to receive by 
reason of such automatic exercise, and to issue or cause its transfer agent to issue a certificate or a book-entry credit to the 
Warrantholder evidencing such shares.

SECTION 4. RESERVATION OF SHARES.

During the term of this Agreement, the Company will at all times have authorized and reserved a sufficient 
number of shares of its Common Stock to provide for the exercise of the rights to purchase Common Stock as provided for 
herein.  If at any time during the term hereof the number of authorized but unissued shares of Common Stock shall not be 
sufficient to permit exercise of this Warrant in full, the Company will take such corporate action 

4

as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purposes.

SECTION 5. NO FRACTIONAL SHARES OR SCRIP.

No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this

Agreement, but in lieu of such fractional shares the Company shall make a cash payment therefor in an amount equal to the
product of (a) the Exercise Price then in effect multiplied by (b) the fraction of a share.

SECTION 6. NO RIGHTS AS SHAREHOLDER/STOCKHOLDER.

Without limitation of any provision hereof, the Warrantholder agrees that this Agreement does not entitle the

Warrantholder to any voting rights or other rights as a shareholder/stockholder of the Company prior to the exercise of any
of the purchase rights set forth in this Agreement.

SECTION 7. WARRANTHOLDER REGISTRY.

The Company shall maintain a registry showing the name and address of the registered holder of this 
Agreement.  The Warrantholder’s initial address, for purposes of such registry, is set forth in Section 12(g) below.  The
Warrantholder may change such address by giving written notice of such changed address to the Company.

SECTION 8. ADJUSTMENT RIGHTS.

The Exercise Price and the number of shares of Common Stock purchasable hereunder are subject to

adjustment from time to time, as follows:

(a)

Merger Event.  In connection with a Merger Event that is a Liquid Sale, this Warrant shall, on and 

after the closing thereof, automatically and without further action on the part of any party or other person, represent the right 
to receive the consideration payable on or in respect of all shares of Common Stock that are issuable hereunder as of
immediately prior to the closing of such Merger Event less the Purchase Price for all such shares of Common Stock (such
consideration to include both the consideration payable at the closing of such Merger Event and all deferred consideration
payable thereafter, if any, including, but not limited to, payments of amounts deposited at such closing into escrow and
payments in the nature of earn-outs, milestone payments or other performance-based payments), and such Merger Event
consideration shall be paid to the Warrantholder as and when it is paid to the holders of the outstanding shares of Common 
Stock.  In connection with a Merger Event that is not a Liquid Sale, the Company shall cause the successor or surviving
entity to assume this Warrant and the obligations of the Company hereunder on the closing thereof, and thereafter this
Warrant shall be exercisable for the same number and type of securities or other property as the Warrantholder would have
received in consideration for the shares of Common Stock issuable hereunder had it exercised this Warrant in full as of 
immediately prior to such closing, at an aggregate Exercise Price no greater than the aggregate Exercise Price in effect as of 
immediately prior to such closing, and subject to further adjustment from time to time in accordance with the provisions of 
this Warrant.  The provisions of this Section 8(a) shall similarly apply to successive Merger Events.

(b)

Reclassification of Shares.  Except for Merger Events subject to Section 8(a), if the Company at any 

time shall, by combination, reclassification, exchange or subdivision of securities or otherwise, change any of the securities 
as to which purchase rights under this Agreement exist into the same or a different number of securities of any other class or 
classes of 

5

securities, this Agreement shall thereafter represent the right to acquire such number and kind of securities as would have 
been issuable as the result of such change with respect to the securities which were subject to the purchase rights under this 
Agreement immediately prior to such combination, reclassification, exchange, subdivision or other change.  The provisions 
of this Section 8(b) shall similarly apply to successive combination, reclassification, exchange, subdivision or other change.

(c)

Subdivision or Combination of Shares.  If the Company at any time shall combine or subdivide its 

Common Stock, (i) in the case of a subdivision, the Exercise Price shall be proportionately decreased and the number of 
shares for which this Warrant is exercisable shall be proportionately increased, or (ii) in the case of a combination, the 
Exercise Price shall be proportionately increased and the number of shares for which this Warrant is exercisable shall be 
proportionately decreased.

(d)

Dividends.  If the Company at any time while this Agreement is outstanding and unexpired shall:

(i)

pay a dividend with respect to the Common Stock payable in additional shares of Common
Stock, then the Exercise Price shall be adjusted, from and after the date of determination of stockholders entitled to receive
such dividend, to that price determined by multiplying the Exercise Price in effect immediately prior to such date of
determination by a fraction (A) the numerator of which shall be the total number of shares of Common Stock outstanding
immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of
Common Stock outstanding immediately after such dividend or distribution, and the number of shares of Common Stock for
which this Warrant is exercisable shall be proportionately increased; or

(ii)

make any other dividend or distribution on or with respect to Common Stock, except any

dividend or distribution specifically provided for in any other clause of this Section 8, then, in each such case, provision
shall be made by the Company such that the Warrantholder shall receive upon exercise or conversion of this Warrant a
proportionate share of any such dividend or distribution as though it were the holder of the Common Stock (or other stock
for which the Common Stock is convertible) as of the record date fixed for the determination of the stockholders of the
Company entitled to receive such dividend or distribution.

(e)

Notice of Certain Events.  If: (i) the Company shall declare any dividend or distribution upon its 

outstanding Common Stock, payable in stock, cash, property or other securities (provided that the Warrantholder in its 
capacity as lender under the Loan Agreement consents to such dividend); (ii) the Company shall offer for subscription pro 
rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (iii) there shall be any 
Merger Event; or (iv) there shall be any voluntary dissolution, liquidation or winding up of the Company; then, in 
connection with each such event, the Company shall give the Warrantholder notice thereof at the same time and in the same 
manner as it gives notice thereof to the holders of outstanding Common Stock.  In addition, if at any time the number of 
shares of Common Stock (or other securities of any other class or classes of securities of the Company for which this 
Warrant is then exercisable) outstanding is reduced such that the number of shares of Common Stock or other securities 
issuable upon exercise of this Warrant shall exceed five percent (5%) of the then outstanding class of such securities, then, 
within three (3) business days of such event, the Company shall give the Warrantholder written notice thereof.

SECTION 9. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

(a) Reservation of Common Stock.  The Company covenants and agrees that all shares of Common Stock  that may 
be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, 
fully paid and non-assessable, and will be free of any taxes, liens, charges or encumbrances of any nature whatsoever; 
provided, that the Common Stock issuable pursuant to this Agreement may be subject to restrictions on transfer under state 
and/or federal securities laws.  The Company has made available to the Warrantholder true, correct and complete copies of 
its Charter and bylaws currently in effect.  The issuance of certificates or book-entry credit for shares of Common Stock 
upon exercise of this Warrant shall be made without charge to the Warrantholder for any issuance tax in respect thereof, or 
other cost incurred by the Company in connection with such exercise and related issuance of shares of Common Stock.  The 
Company further covenants and agrees that the Company will, at all times during the term hereof, have authorized and 
reserved, free from preemptive rights, a sufficient number of shares of Common Stock to provide for the exercise of the 
rights represented by this Warrant.

(b) Due Authority.  The execution and delivery by the Company of this Agreement and the performance of all 
obligations of the Company hereunder, including the issuance to the Warrantholder of the right to acquire the shares of 
Common Stock, have been duly authorized by all necessary corporate action on the part of the Company.  This Agreement: 
(i) does not violate the Charter or the Company’s current bylaws; (ii) does not contravene any law or governmental rule, 
regulation or order applicable to the Company; and (iii) except as could not reasonably be expected to have a Material 
Adverse Effect (as defined in the Loan Agreement), does not and will not contravene any provision of, or constitute a default 
under, any indenture, mortgage, contract or other instrument to which the Company is a party or by which it is bound.  This 
Agreement constitutes a legal, valid and binding agreement of the Company, enforceable in accordance with its terms, 
except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting 
creditors’ rights generally (including, without limitation, fraudulent conveyance laws) and by general principles of equity, 
regardless of whether considered in a proceeding in equity or at law.

(c) Consents and Approvals.  No consent or approval of, giving of notice to, registration with, or taking of any other 

action in respect of any state, federal or other governmental authority or agency is required with respect to the execution, 
delivery and performance by the Company of its obligations under this Agreement, except for the filing of notices pursuant 
to Regulation D under the Act and any filing required by applicable state securities law, which filings will be effective by the 
time required thereby.

(d)

Exempt Transaction.  Subject to the accuracy of the Warrantholder’s representations in Section 10, the 

issuance of the Common Stock upon exercise of this Agreement will constitute a transaction exempt from (i) the registration 
requirements of Section 5 of the Act, in reliance upon Section 4(a)(2) thereof, and (ii) the qualification requirements of the 
applicable state securities laws.

(e) Information Rights.  At all times (if any) prior to the earlier to occur of (x) the date on which all shares of 
Common Stock issued on exercise of this Warrant have been sold, or (y) the expiration or earlier termination of this Warrant, 
when the Company shall not be required to file reports pursuant to Section 13 or 15(d) of the Exchange Act or shall not have 
timely filed all such required reports, the Warrantholder shall be entitled to the information rights contained in Section 7.1(b) 
– (f) of the Loan Agreement, and in any such event Section 7.1(b) – (f) of the Loan 

7

Agreement is hereby incorporated into this Agreement by this reference as though fully set forth herein, provided, however,
that the Company shall not be required to deliver a Compliance Certificate once all Indebtedness (as defined in the Loan
Agreement) owed by the Company and its Subsidiaries to Warrantholder has been repaid.

(f) Registration of Shares.  If the Company proposes to register (including, for this purpose, a registration effected 

by the Company for the sale by the Company of its securities and/or the resale of securities of the Company by security 
holders other than the Warrantholder) the sale or resale of any of its Common Shares or other securities under the Act in 
connection with the public offering of such securities (other than in an Excluded Registration), the Company shall cause to 
be registered all of the Registrable Securities in such registration. The Company shall have the right to terminate or 
withdraw any registration initiated by it under this Section 9(f) before the effective date of such registration, provided that
the Company’s obligations to register the Registrable Securities under this Section 9(f) in any subsequent registration (other
than in an Excluded Registration) shall continue following any such termination or withdrawal. All fees and expenses
incident to the Company’s performance of or compliance with its obligations under this Section 9(f) (excluding any
underwriting discounts and selling commissions) shall be borne by the Company.

(g) Rule 144 Compliance.  The Company shall, at all times prior to the earlier to occur of (i) the date of sale or other 

disposition by Warrantholder of this Warrant or all shares of Common Stock issued on exercise of this Warrant,  (ii) the 
registration pursuant to subsection (f) above of the shares issued on exercise of this Warrant, or (iii) the expiration or earlier 
termination of this Warrant if the Warrant has not been exercised in full or in part on such date, use all commercially 
reasonable efforts to timely file all reports required under the Exchange Act and otherwise timely take all actions necessary 
to permit the Warrantholder to sell or otherwise dispose of this Warrant and the shares of Common Stock issued on exercise 
hereof pursuant to Rule 144 promulgated under the Act (“Rule 144”), provided that the foregoing shall not apply in the event 
of a Merger Event following which the successor or surviving entity is not subject to the reporting requirements of the 
Exchange Act.  If the Warrantholder proposes to sell Common Stock issuable upon the exercise of this Agreement in 
compliance with Rule 144, then, upon the Warrantholder’s written request to the Company, the Company shall furnish to the 
Warrantholder, within five (5) business days after receipt of such request, a written statement confirming the Company’s 
compliance with the filing and other requirements of such Rule 144.

the Warrantholder has no present intention of selling or engaging in any public distribution of the same except pursuant to a 
registration or exemption.

transactions in the Common Stock.

SECTION 11. TRANSFERS.

Subject to compliance with applicable federal and state securities laws, this Agreement and all rights 

hereunder are transferable, in whole or in part, without charge to the holder hereof (except for transfer taxes) upon surrender 
of this Agreement properly endorsed.  Each taker and holder of this Agreement, by taking or holding the same, consents and 
agrees that this Agreement, when endorsed in blank, shall be deemed negotiable, and that the holder hereof, when this 
Agreement shall have been so endorsed and its transfer recorded on the Company’s books, shall be treated by the Company 
and all other persons dealing with this Agreement as the absolute owner hereof for any purpose and as the person entitled to 
exercise the rights represented by this Agreement.  The transfer of this Agreement shall be recorded on the books of the 
Company upon receipt by the Company of a notice of transfer in the form attached hereto as Exhibit III (the “Transfer
Notice”), at its principal offices and the payment to the Company of all transfer taxes and other governmental charges 
imposed on such transfer.  Until the Company receives such Transfer Notice, the Company may treat the registered owner 
hereof as the owner for all purposes.  Notwithstanding anything herein or in any legend to the contrary, the Company shall 
not require an opinion of counsel in connection with any sale, assignment or other transfer by the Warrantholder of this 
Warrant (or any portion hereof or any interest herein) or of any shares of Common Stock issued upon any exercise hereof to 
an affiliate (as defined in Regulation D) of the Warrantholder, provided that such affiliate is an “accredited investor” as 
defined in Regulation D.

SECTION 12. MISCELLANEOUS.

(a) Effective Date.  The provisions of this Agreement shall be construed and shall be given effect in all respects as if 

it had been executed and delivered by the Company on the date hereof.  This Agreement shall be binding upon any 
successors or assigns of the Company.

(b) Remedies.  In the event of any default hereunder, the non-defaulting party may proceed to protect and enforce its 

rights either by suit in equity and/or by action at law, including but not limited to an action for damages as a result of any 
such default, and/or an action for specific performance for any default where the Warrantholder will not have an adequate 
remedy at law and where damages will not be readily ascertainable.

(c) No Impairment of Rights.  The Company will not, by amendment of its Charter or through any other means, 
avoid or seek to avoid the observance or performance of any of the terms of this Agreement, but will at all times in good 
faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate in 
order to protect the rights of the Warrantholder against impairment.

9

(d) Additional Documents.  The Company agrees to supply such other documents as the Warrantholder may from

invalid, illegal or unenforceable, the remaining provisions of this Agreement shall be unimpaired, and the invalid, illegal or 
unenforceable provision shall be replaced by a mutually acceptable valid, legal and enforceable provision, which comes 
closest to the intention of the parties underlying the invalid, illegal or unenforceable provision.

(g) Notices.  Except as otherwise provided herein, any notice, demand, request, consent, approval, declaration, 

service of process or other communication that is required, contemplated, or permitted under this Agreement or with respect 
to the subject matter hereof shall be in writing, and shall be deemed to have been validly served, given, delivered, and

or to such other address as each party may designate for itself by like notice.

(h) Entire Agreement; Amendments.  This Agreement constitutes the entire agreement and understanding of the 

parties hereto in respect of the subject matter hereof, and supersedes and replaces in their entirety any prior proposals, term 
sheets, letters, negotiations or other documents or agreements, whether written or oral, with respect to the subject matter 
hereof.  None of the terms of this Agreement may be amended except by an instrument executed by each of the parties 
hereto.

(i) Headings.  The various headings in this Agreement are inserted for convenience only and shall not affect the 

meaning or interpretation of this Agreement or any provisions hereof.

(j) Advice of Counsel.  Each of the parties represents to each other party hereto that it has discussed (or had an 

opportunity to discuss) with its counsel this Agreement and, specifically, the provisions of Sections 12(n), 12(o), 12(p), 12(q) 
and 12(r).

(k) No Strict Construction.  The parties hereto have participated jointly in the negotiation and drafting of this 

Agreement.  In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if 
drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by 
virtue of the authorship of any provisions of this Agreement.

(l) No Waiver.  No omission or delay by the Warrantholder at any time to enforce any right or remedy reserved to 

it, or to require performance of any of the terms, covenants or provisions hereof by the Company at any time designated, 
shall be a waiver of any such right or remedy to which the Warrantholder is entitled, nor shall it in any way affect the right of 
the Warrantholder to enforce such provisions thereafter during the term of this Agreement.

(m) Survival.  All agreements, representations and warranties contained in this Agreement or in any document 

delivered pursuant hereto shall be for the benefit of the Warrantholder and shall survive the execution and delivery of this 
Agreement and the expiration or other termination of this Agreement.

(n) Governing Law.  This Agreement has been negotiated and delivered to the Warrantholder in the State of 
California, and shall be deemed to have been accepted by the Warrantholder in the State of California.  Delivery of Common 
Stock to the Warrantholder by the Company under this Agreement is due in the State of California.  This Agreement shall be 

11

governed by, and construed and enforced in accordance with, the laws of the State of California, excluding conflict of laws
principles that would cause the application of laws of any other jurisdiction.

(o) Consent to Jurisdiction and Venue.  All judicial proceedings arising in or under or related to this Agreement may 

be brought in any state or federal court of competent jurisdiction located in the State of California.  By execution and 
delivery of this Agreement, each party hereto generally and unconditionally: (i) consents to personal jurisdiction in Santa 
Clara County, State of California; (ii) waives any objection as to jurisdiction or venue in Santa Clara County, State of 
California; (iii) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (iv) 
irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement.  Service of process on 
any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance with the 
requirements for notice set forth in Section 12(g), and shall be deemed effective and received as set forth in Section 12(g).  
Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either 
party to bring proceedings in the courts of any other jurisdiction.

(p) Mutual Waiver of Jury Trial.  Because disputes arising in connection with complex financial transactions are 

most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and 
federal laws to apply (rather than arbitration rules), the parties desire that their disputes arising under or in connection with 
this Warrant be resolved by a judge applying such applicable laws.  EACH OF THE COMPANY AND THE 
WARRANTHOLDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE 
OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM 
(COLLECTIVELY, “CLAIMS”) ASSERTED BY THE COMPANY AGAINST THE WARRANTHOLDER OR ITS 
ASSIGNEE OR BY THE WARRANTHOLDER OR ITS ASSIGNEE AGAINST THE COMPANY RELATING TO THIS 
WARRANT.  This waiver extends to all such Claims, including Claims that involve persons or entities other the Company 
and the Warrantholder; Claims that arise out of or are in any way connected to the relationship between the Company and 
the Warrantholder; and any Claims for damages, breach of contract, specific performance, or any equitable or legal relief of 
any kind, arising out of this Agreement.

(q) Arbitration.  If the Mutual Waiver of Jury Trial set forth in Section 12(p) is ineffective or unenforceable, the 

parties agree that all Claims shall be submitted to binding arbitration in accordance with the commercial arbitration rules of 
JAMS (the “Rules”), such arbitration to occur before one arbitrator, which arbitrator shall be a retired California state judge 
or a retired Federal court judge.  Such proceeding shall be conducted in Santa Clara County, State of California, with 
California rules of evidence and discovery applicable to such arbitration.  The decision of the arbitrator shall be binding on 
the parties, and shall be final and nonappealable to the maximum extent permitted by law.  Any judgment rendered by the 
arbitrator may be entered in a court of competent jurisdiction and enforced by the prevailing party as a final judgment of 
such court.

(r) Pre-arbitration Relief.  In the event Claims are to be resolved by arbitration, either party may seek from a court 
of competent jurisdiction identified in Section 12(o), any prejudgment order, writ or other relief and have such prejudgment 
order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise 
subject to resolution by binding arbitration.

(s) Counterparts.  This Agreement and any amendments, waivers, consents or supplements hereto may be executed 

in any number of counterparts (including by facsimile or 

12

electronic delivery (PDF)), and by different parties hereto in separate counterparts, each of which when so delivered shall be
deemed an original, but all of which counterparts shall constitute but one and the same instrument.

(t) Specific Performance.  The parties hereto hereby declare that it is impossible to measure in money the damages 

which will accrue to the Warrantholder by reason of the Company’s failure to perform any of the obligations under this 
Agreement and agree that the terms of this Agreement shall be specifically enforceable by the Warrantholder.  If the 
Warrantholder institutes any action or proceeding to specifically enforce the provisions hereof, any person against whom
