Item 1.    Business.

OVERVIEW

PART I

We are a biotechnology company focused on discovering, developing, and commercializing novel gene and cell therapies and vaccines that improve health
and offer hope for patients across the globe.

Our cutting-edge technology pipeline includes:

• Modifier Gene Therapy Platform — Based on the use of nuclear hormone receptors ("NHRs"), we believe our modifier gene therapy platform
has  the  potential  to  address  many  retinal  diseases,  including  retinitis  pigmentosa  ("RP"),  Leber  congenital  amaurosis  ("LCA"),  dry  age-related
macular degeneration ("AMD"), and Stargardt disease, with a single mutation-agnostic therapy.

• Regenerative  Medicine  Cell  Therapy  Platform  —  Our  Phase  3-ready  regenerative  medicine  cell  therapy  platform  technology,  NeoCart

(autologous chondrocyte-derived neocartilage), is being developed for the repair of knee cartilage injuries in adults.

• Vaccines  —  COVAXIN  is  our  whole-virion  inactivated  intramuscular  COVID-19  vaccine  candidate,  which  we  are  developing  for  the  North
American  market.  We  are  also  developing  a  novel  inhaled  mucosal  vaccine  platform,  which  includes  OCU500,  a  bivalent  COVID-19  vaccine;
OCU510, a seasonal quadrivalent flu vaccine; and OCU520, a combination quadrivalent seasonal flu and bivalent COVID-19 vaccine.

• Novel Biologic Therapy for Retinal Diseases — OCU200 is a novel fusion protein containing parts of human tumstatin and transferrin. OCU200

is designed to treat diabetic macular edema ("DME"), diabetic retinopathy ("DR"), and wet AMD.

Modifier Gene Therapy Platform

We are developing a modifier gene therapy platform designed to fulfill unmet medical needs related to retinal diseases, including inherited retinal diseases
("IRDs"), such as RP, LCA, and Stargardt disease, as well as dry AMD. Our modifier gene therapy platform is based on the use of NHRs, which have the
potential to restore homeostasis — the basic biological processes in the retina. Unlike single-gene replacement therapies, which only target one genetic
mutation,  we  believe  that  our  modifier  gene  therapy  platform,  through  its  use  of  NHRs,  represents  a  novel  approach  that  has  the  potential  to  address
multiple retinal diseases caused by mutations in multiple genes with one product, and potentially address complex diseases that are potentially caused by
imbalances in multiple gene networks. OCU400, our first product candidate in our modifier gene therapy platform, has received Orphan Drug Designation
("ODD") from the FDA for nuclear receptor subfamily 2 group E member 3 ("NR2E3")-related RP and LCA and Orphan Medicinal Product Designation
("OMPD") from the European Commission ("EC"), based on the recommendation of the European Medicines Agency ("EMA"), for RP and LCA. These
ODD and OMPD designations represent gene-agnostic broad coverage for RP and LCA, and are not mutation-specific designations.

We are conducting a Phase 1/2 clinical trial to assess the safety of unilateral subretinal administration of OCU400 in patients with NR2E3 and rhodopsin
("RHO")-related RP and centrosomal protein 290 ("CEP290")-related LCA in the United States. We have completed dosing patients with RP in the dose-
escalation  portion  of  the  clinical  trial,  which  enrolled  10  subjects  to  receive  a  low,  medium,  or  high  dose  of  OCU400  in  the  subretinal  space.  We  are
continuing to enroll subjects with RP and LCA in this clinical trial to receive the high dose, which was determined to be the maximum tolerable dose from
the dose-escalation portion of the clinical trial. We intend to initiate a Phase 1/2 pediatric clinical trial for OCU400 for the treatment of RP and LCA in the
second quarter of 2023 and a Phase 3 clinical trial for OCU400 for the treatment of RP and LCA near the end of 2023, subject to discussions with the FDA.

We are also developing OCU410 and OCU410ST to utilize the nuclear receptor genes RAR-related orphan receptor A ("RORA") for the treatment of dry
AMD and Stargardt disease, respectively. We are currently executing IND-enabling studies and we intend to submit IND applications in the second quarter
of 2023 to initiate Phase 1/2 clinical trials.

Regenerative Medicine Cell Therapy Platform

NeoCart is a Phase 3-ready, regenerative medicine cell therapy technology that combines breakthroughs in bioengineering and cell processing to enhance
the  autologous  cartilage  repair  process.  NeoCart  is  a  three-dimensional  tissue-engineered  disc  of  new  cartilage  that  is  manufactured  by  growing
chondrocytes, the cells responsible for maintaining cartilage health. The chondrocytes

1

Table of Contents

are derived from the patient on a unique scaffold. In this therapy, healthy cartilage tissue is grown and implanted in the patient. We believe NeoCart has the
potential to accelerate healing and reduce pain by reconstructing a patient's previously damaged knee cartilage. It is designed to treat pain at the source,
improve  function,  and  potentially  prevent  a  patient's  progression  to  osteoarthritis  ("OA").  The  FDA  granted  a  regenerative  medicine  advanced  therapy
("RMAT") designation to NeoCart for the repair of full-thickness lesions of knee cartilage injuries in adults. We have received concurrence from the FDA
on  the  confirmatory  Phase  3  clinical  trial  design.  We  are  renovating  an  existing  facility  into  a  current  GMP  facility  in  accordance  with  the  FDA's
regulations in support of NeoCart manufacturing for Phase 3 clinical trial material. We intend to initiate the Phase 3 clinical trial in the first half of 2024,
subject to discussions with the FDA.

Vaccines

Intramuscular COVID-19 Vaccine

We have a Co-Development, Supply and Commercialization Agreement with Bharat Biotech (as amended, the "Covaxin Agreement"), pursuant to which
we obtained an exclusive right and license under certain of Bharat Biotech's intellectual property rights, with the right to grant sublicenses, to develop,
manufacture, and commercialize COVAXIN for the prevention of COVID-19, caused by SARS-CoV-2, in the United States, its territories, and possessions,
Canada, and Mexico (the "Ocugen Covaxin Territory"). COVAXIN is intended for administration into the deltoid muscle of the upper arm, in two doses
occurring 28 days apart.

A Phase 3 clinical trial conducted by Bharat Biotech in India in 25,798 adults, ages 18 years and older, who were healthy or had stable chronic medical
conditions reported an overall estimated vaccine efficacy of COVAXIN against COVID-19 of 77.8%, with efficacy against severe COVID-19 of 93.4%. In
January 2023, we announced top-line results from our Phase 2/3 immuno-bridging and broadening clinical trial in the United States evaluating COVAXIN
for adults ages 18 years and older. The clinical trial was designed to evaluate whether the immune response observed in participants in Bharat Biotech's
Phase 3 clinical trial in India is similar to a demographically representative, adult population in the United States. The clinical trial met both co-primary
immunogenicity endpoints and no serious adverse events ("SAEs") related to COVAXIN were identified. We additionally plan to work with government
agencies in the United States to obtain funding in order to comply with the requirements of a Biologics License Application ("BLA") submission, including
funding to initiate an adult safety clinical trial subject to discussions with the FDA.

In July 2021, we completed our rolling submission to Health Canada for COVAXIN. The rolling submission process, which was conducted through our
Canadian subsidiary, Vaccigen Ltd. ("Vaccigen"), was recommended and accepted under the Minister of Health's Interim Order Respecting the Importation,
Sale and Advertising of Drugs for Use in Relation to COVID-19 ("Interim Order") and transitioned to a New Drug Submission ("NDS") for COVID-19. In
August 2022, we withdrew our NDS based on discussions with Health Canada and are evaluating the requirements for resubmitting an updated NDS. In
Mexico, the Comisión Federal para la Protección contra Riesgos Sanitarios ("COFEPRIS") authorized emergency use for COVAXIN for adults ages 18
years  and  older,  which  remains  active.  We  are  in  discussions  with  Consejo  Nacional  de  Ciencia  y  Tecnología  in  Mexico  ("CONACYT")  regarding  our
submission for emergency use authorization ("EUA") for COVAXIN for pediatric use in ages five to 18 years.

Inhaled Mucosal Vaccines

In September 2022, we entered into an exclusive license agreement ("WU License Agreement") with The Washington University in St. Louis ("Washington
University"),  pursuant  to  which  we  obtained  the  rights  to  develop,  manufacture,  and  commercialize  an  inhaled  mucosal  COVID-19  vaccine  for  the
prevention of COVID-19 in the United States, Europe, and Japan. The WU License Agreement was amended in January 2023 to add the countries of South
Korea, Australia, and China to the territory rights (together with the United States, Europe, and Japan, the "Mucosal Vaccine Territory"). Utilizing these
rights,  we  are  developing  a  novel  inhaled  mucosal  vaccine  platform,  which  includes  OCU500,  a  bivalent  COVID-19  vaccine;  OCU510,  a  seasonal
quadrivalent flu vaccine; and OCU520, a combination quadrivalent seasonal flu and bivalent COVID-19 vaccine. As these vaccine candidates are being
developed to be administered through inhalation, we believe they have the potential to generate rapid local immunity in the upper airways and lungs where
viruses enter and infect the body, which we believe may help reduce or prevent infection and transmission as well as provide protection against new virus
variants.  OCU510  is  being  developed  for  the  global  market.  We  intend  to  initiate  IND-enabling  studies  and  work  closely  with  government  agencies  to
obtain funding for the development of these inhaled mucosal vaccines.

Table of Contents

Novel Biologic Therapy for Retinal Diseases

We are developing OCU200, which is a novel fusion protein containing parts of human tumstatin and transferrin. OCU200 is designed to treat DME, DR,
and  wet  AMD.  We  have  completed  the  technology  transfer  of  manufacturing  processes  to  our  contract  development  and  manufacturing  organization
("CDMO") and have produced clinical trial materials to initiate a Phase 1 clinical trial. We submitted an IND application to the FDA in February 2023 to
initiate a Phase 1 clinical trial targeting DME.

OUR STRATEGY

We are developing novel solutions to medical challenges and approaching healthcare innovation with purpose and agility to deliver new options for people
facing  serious  diseases  and  conditions.  Our  product  candidates  have  the  potential  to  cure  blindness  diseases,  treat  serious  conditions  such  as  articular
cartilage lesions, reduce the transmission of COVID-19, and make a significant impact in the ever-evolving COVID-19 landscape. Key elements of the
strategy we employ to accomplish this mission include:

•

Continuing to advance our modifier gene therapy platform into and through clinical development.

We  are  developing  our  modifier  gene  therapy  platform,  inclusive  of  OCU400,  OCU410,  and  OCU410ST,  for  the  treatment  of  multiple  IRDs,
including RP, LCA, and Stargardt disease, as well as dry AMD. We are continuing to enroll patients in a Phase 1/2 clinical trial for OCU400 for
the treatment of RP and LCA and have completed dosing patients in the dose-escalation portion of this clinical trial. We intend to initiate a Phase
1/2 pediatric clinical trial for OCU400 for the treatment of RP and LCA in the second quarter of 2023 and a Phase 3 clinical trial for OCU400 for
the treatment of RP and LCA near the end of 2023, subject to discussions with the FDA. We are executing IND-enabling studies for OCU410 and
OCU410ST and we intend to submit IND applications in the second quarter of 2023 to initiate Phase 1/2 clinical trials.

•

Expanding and exploring partnerships with current and future key collaborators and commercial partners to maximize patient access, global
reach, and the value of our product candidates.

We intend to explore strategic licensing, acquisition, and collaboration opportunities with qualified partners to maximize the potential benefit of
our product candidates on patients globally and to expand our product candidate pipeline to support our future growth.

• Obtaining government funding to advance our vaccine programs towards commercialization.

We  are  developing  a  novel  inhaled  mucosal  vaccine  platform,  which  includes  OCU500,  a  bivalent  COVID-19  vaccine;  OCU510,  a  seasonal
quadrivalent  flu  vaccine;  and  OCU520,  a  combination  quadrivalent  seasonal  flu  and  bivalent  COVID-19  vaccine.  We  obtained  the  rights  to
develop, manufacture, and commercialize an inhaled mucosal COVID-19 vaccine in the Mucosal Vaccine Territory from Washington University.
We are developing the seasonal flu component of this inhaled mucosal vaccine platform internally. As these mucosal vaccine candidates are being
developed to be administered through inhalation, we believe they have the potential to generate rapid local immunity in the upper airways and
lungs  where  viruses  enter  and  infect  the  body,  which  is  particularly  important  during  times  of  peak  transmission.  OCU520,  our  combination
quadrivalent seasonal flu and bivalent COVID-19 vaccine, is designed to provide the unique ease of getting both an annual COVID-19 booster
vaccine and an annual seasonal flu vaccine in one vaccine.

We also announced top-line results from our Phase 2/3 immuno-bridging and broadening clinical trial in the United States evaluating COVAXIN
for adults ages 18 years and older. The Phase 2/3 clinical trial met both co-primary immunogenicity endpoints and no SAEs related to COVAXIN
were identified. COVAXIN is formulated with the inactivated SARS-CoV-2 virus, an antigen, and an adjuvant, which is a common approach to
vaccine design. Accordingly, COVAXIN represents an important additional vaccine option for individuals that are looking for a well-established
approach to vaccine development and manufacturing as well as a vaccine that elicits robust cellular immune memory to SARS-CoV-2.

We intend to work closely with government agencies to obtain funding to initiate clinical trials to support the regulatory submissions for these
vaccines in their respective territories.

•

Advancing  the  clinical  development  of  our  regenerative  medicine  platform  towards  market  authorization  and  developing  in-house
manufacturing capability.

We are developing NeoCart, our regenerative medicine platform technology for the repair of knee cartilage injuries in adults. We have received
concurrence from the FDA on the confirmatory Phase 3 clinical trial design. We are renovating an existing facility into a current GMP facility in
accordance with the FDA's regulations in support of

Product  Designations.  OCU400  has  received  ODD  from  the  FDA  for  NR2E3-related  RP  and  LCA  and  OMPD  from  the  EC,  based  on  the
recommendation of the EMA, for RP and LCA. These designations demonstrate the potential broad-spectrum application of OCU400, through its
use of NHRs, to treat the more than 125 genes associated with RP and LCA with one product rather than developing individual treatments for each
gene  mutation.  Additionally,  OCU400  had  previously  received  ODDs  from  the  FDA  for  the  treatment  of  certain  disease  genotypes:  NR2E3,
CEP290, RHO, and phosphodiesterase 6B ("PDE6ß") mutation-associated inherited retinal degenerations. NeoCart, our regenerative medicine cell
therapy technology, was granted RMAT designation from the FDA for the repair of knee cartilage injuries in adults. The RMAT designation was
created to expedite the development and review of regenerative medicine therapies intended to treat, modify, reverse, or cure a serious condition.

OUR PRODUCT CANDIDATE PIPELINE

Our product candidate pipeline is summarized in the following chart:

OUR MODIFIER GENE THERAPY PLATFORM AND GENE THERAPY PRODUCT CANDIDATES

We are developing our modifier gene therapy platform, inclusive of OCU400, OCU410, and OCU410ST for the treatment of multiple IRDs, such as RP,
LCA,  and  Stargardt  disease,  as  well  as  dry  AMD.  Our  modifier  gene  therapy  platform  is  a  cutting-edge  technology  licensed  from  SERI,  an  affiliate  of
Harvard  Medical  School,  and  involves  the  targeted  delivery  and  expression  of  one  or  more  NHRs  in  the  disease  tissues  and  is  designed  to  introduce  a
functional gene to modify the expression of multiple genes and gene-networks, which potentially enables it to address multiple retinal diseases with one
product.

Modifier Gene Therapy Platform Based on the Use of NHRs

NHRs are intracellular receptors that regulate gene expression, acting as master regulator genes in the retina. NHRs play a vital role in regulating retinal
cell development, maturation, metabolism, visual cycle function, survival, and maintaining the cellular and molecular homeostasis in retinal tissues. Our
modifier gene therapy platform is designed to target NHRs to potentially provide therapeutic benefit to patients suffering from genetically diverse IRDs.
The  use  of  genetic  modifiers  represent  a  broadened  means  of  potentially  treating  a  variety  of  retinal  degenerative  diseases,  as  compared  to  single-gene
replacement therapy. While single-gene replacement therapies have shown tremendous promise in rare retinal diseases, they are highly specific and cannot
improve a multitude of disease-causing genetic defects. Our modifier gene therapy platform has the potential to restore retinal integrity and function across
a range of genetically diverse IRDs and other degenerative retinal diseases providing us with significant potential long-term value.

Our  modifier  gene  therapy  platform  encompasses  the  targeted  delivery  and  expression  of  certain  NHRs  that  are  expressed  naturally  in  retinal  tissue.
Preclinical studies have shown that NR2E3, a member of the NHR family, is a dual activator and repressor that, with other transcription factors, modulates
cell fate and differentiation of rod and cone photoreceptor cells, specialized cells for detecting light, in the eye. Disease outcome is a result of a primary
mutation as well as modifier alleles. NR2E3 is a master regulator of several key pathways in retinal development and function. NR2E3 potentially prevents
and rescues degenerating retina by resetting the homeostatic state of key gene networks in the presence of a primary mutation.

The delivery of Nr2e3 in a mouse lacking a functional Nr2e3 gene restored the retina structure and function. We believe that NR2E3 may partially or fully
rescue photoreceptors from degeneration in patients with IRDs and improve patients' vision. It

5

Table of Contents

was also demonstrated preclinically that RORA offers a protective allele in AMD where the loss of photoreceptor cells leads to blindness. NR2E3 regulates
the expression of both Nuclear Receptor Subfamily 1 Group D Member 1 ("NR1D1") and RORA. Thus, the nuclear receptors work in overlapping networks
to modulate normal retinal development and function. These receptors impact gene expression of hundreds of genes and numerous networks and, as such,
may be potent modifiers of retinal disease and degeneration.

Results of Preclinical Studies Support the Potential Efficacy of NR2E3 Modifier Gene Therapy

The efficacy of Nr2e3 was evaluated in five unique mouse models of IRDs in which treatment with the adeno-associated viral ("AAV")8-Nr2e3 gene by
subretinal  injection  effectively  rescued  multiple  genetically  diverse  IRDs  by  protecting  photoreceptors  from  further  damage  after  disease  onset.  These
models represent a heterogeneous group of diseases in humans and are relevant in establishing the modifier role of NR2E3. The five IRD models evaluated
/J  ("rd16"),  and
were:  FVB-Pde6ß 
Nr2e3 /J ("rd7"). rd1  is  PDE6β-associated  RP,  Rho
  are  both  RHO-associated  RP,  rd16  is  LCA,  and  rd7  is  enhanced  S-cone  syndrome.
C57BL6/J  ("B6")  in  these  models  represents  the  control.  The  results  were  evaluated  using  fundus  imaging,  electroretinogram  ("ERG"),  histology,  and
immunostaining of retinal layers. This preclinical data was published in Nature Gene Therapy.

This study showed that the administration of AAV8-Nr2e3 therapy improved clinical, histological, functional, and molecular disease outcomes in each of
the  five  models  of  IRDs.  These  studies  demonstrated  that  the  mechanism  of  Nr2e3  therapy  involves  resetting  key  retinal  transcription  factors  and  key
biological  networks  that  work  in  concert  with  Nr2e3  to  modulate  the  homeostatic  state  of  the  retina.  The  study  is  based  on  the  principle  that  disease
outcome is rarely due to a single gene mutation; rather, it is a result of the combinatorial mutational load on the biological system, which is often strongly
influenced by other factors such as modifier genes. The models demonstrate the potential potency of a novel modifier gene therapy to elicit broad-spectrum
therapeutic benefits in early (Figure 1, Figure 2, and Figure 4) and advanced stages (Figure 1, Figure 3, and Figure 5) of IRDs and serve as a broad-
spectrum gene therapy to reduce retinal degeneration.

a more moderate increase (three to six layers of ONL in early stage rescue IRD models) compared to the untreated eyes of each model. ONL cell layer
numbers in the rd7 model do not start degenerating until four to five months of age and as such is excluded from Figure 1 above. Although only partial
rescue was observed in these models, results of research conducted by third parties suggests that retention of only a single layer of photoreceptor cells can
maintain minimal visual function suggesting that an increase of even 20% is significant. In the advanced stage rescue IRD models, the results of which are

depicted in the bottom half of Figure 1, improvement varied from ~30 to 80% of the retina in the Rho , Rho

depending on distribution efficiency throughout the retina. Approximately three to five layers of ONL cells were preserved in Nr2e3 treated mice compared
with untreated mice that show less than or equal to one layer of ONL remaining. We believe Nr2e3 therapy has great promise in potentially restoring
retinal development.

red fundus with increased and pronounced vessels and this fundus observation resolves with Nr2e3 administration. Improvement was observed in the rd7

Figure 4 displays the H/E staining results from AAV8-Nr2e3 treated and untreated mice in different early-stage IRD models. The H/E staining revealed that
subretinal delivery of AAV8-Nr2e3 rescued photoreceptor cells and helped maintain retinal integrity of IRD retinas in all models. Additionally, the rd7
model presents with increased cone cells with whorls and rosettes in the ONL. These retinal whorls and rosettes, that are characteristics of the rd7
phenotype, resolved following Nr2e3 treatment, suggesting that the delivery of Nr2e3 can restore normal retinal development.

Figure 5 displays the H/E staining results from AAV8-Nr2e3 treated and untreated mice in different advanced stage IRD models. The H/E staining shows
the reduction of retinal degeneration by Nr2e3 therapy in each model.

Improved ERG results were also observed in AAV8-Nr2e3 treated IRD retinas in addition to the above results that displayed the rescue of ONL layers,
improvement in fundus imaging, and improvement in H/E staining. Human vision is enabled by three primary modes: scotopic vision, photopic vision, and
mesopic vision. Scotopic vision is monochromatic vision in very low light, which functions primarily due to rod cells in the eye. Photopic vision is vision
under  well-lit  conditions,  which  provides  for  color  perception  and  functions  primarily  due  to  cone  cells  in  the  eye.  Mesopic  vision  is  a  combination  of
scotopic and photopic vision in low lighting, which functions due to a combination of rod and cone cells in the eye. IRD disease progression results in the
loss  of  rod  and  cone  function  that  is  assessed  by  abnormal  ERG  responses.  In  the  below  study,  the  visual  function  of  Nr2e3  treated  IRD  retinas  was
examined in four out of five IRD strains, excluding rd7, by recording scotopic  and  photopic  ERGs  to  evaluate  rod-  and  cone-driven  responses.  Treated
mice showed improvement in retinal ERG signal, both in scotopic and photopic conditions (Figure 6).

The safety of Nr2e3 was evaluated in healthy mice following subretinal administration. B6 mice were treated with AAV8-Nr2e3-green fluorescent protein
("GFP") fusion construct at post-natal day zero and evaluated after both seven days and one month for any toxic effect as well as expression of Nr2e3-GFP
fusion  protein  in  the  retina.  The  expression  of  the  Nr2e3  protein  in  a  mouse  retina  did  not  show  any  detrimental  effect  on  retinal  cells,  including
photoreceptors (Figure 7).  Also,  there  was  no  difference  in  retinal  anatomy  as  indicated  by  fundus,  histology  (the  cell  layers),  expression  of  opsin  and

expression. The expression level of five other essential retinal transcription factors (Nr1d1, Nrl, Crx, Rora, and Thrb) were determined in Nr2e3 treated and

Overview of RP and LCA and Current Treatment Options

IRDs are caused by genetic mutations that are passed down within families and lead to progressive disease, severe visual impairment, and blindness. They
are  a  diverse  disease  class  with  large  phenotypic  and  genetic  heterogeneity.  IRDs  are  a  common  cause  of  irreversible  blindness  due  to  retinal  cell
degeneration. Treating these conditions has been a significant challenge due to the sheer volume of potential therapeutic gene targets. Gene replacement
therapy is a promising approach to provide sustained restoration of normal retinal function for a mutated gene, but such therapies can only address one gene
at a time, limiting their potential therapeutic use. Developing a custom gene therapy for each of the more than 125 mutated genes linked to RP and LCA
would not only be expensive but also may not be possible due to size, class, or localization that will impact delivery of the gene. Not all genes and disease
expressions are amenable to gene therapy. For example, the genetic mutations of approximately 40% of RP patients remain unknown with few or no known
therapeutic options available. Modifier gene therapy to ameliorate multiple forms of RP and LCA without requiring knowledge of the mutated gene, may
provide a potentially robust and feasible treatment for RP and LCA.

RP and LCA are the most common IRDs involving photoreceptors and the retinal pigment epithelium ("RPE"). RP is a group of rare, genetic disorders that
involve  a  breakdown  and  loss  of  cells  in  the  retina.  RP  affects  approximately  110,000  and  190,000  individuals  in  the  United  States  and  Europe,
respectively. In RP, progressive retinal degeneration starts in the mid-periphery and advances toward the macula and the fovea. The fovea is the part of the
retina that is responsible for sharp central vision. Common symptoms of RP include difficulty seeing in poor lighting or in the dark, loss of central vision or
side (peripheral) vision, and difficulty reading print and deciphering detailed images. RP is associated with over 100 mutated genes that affect

10

Table of Contents

1.5 million individuals worldwide. RP is heterogeneous and varies greatly in age of onset, rate of progression, and even genetic etiology, yet a common
pathology of photoreceptor cell degeneration develops.

There is currently no approved treatment that slows or stops the progression of multiple forms of RP. Proposed treatments for RP include gene-replacement
therapy,  retinal  implant  devices,  retinal  transplantation,  stem  cells,  vitamin  therapy,  and  other  pharmacological  treatments.  While  gene-replacement
therapies may provide a new functional gene, they do not necessarily eliminate the underlying genetic defect, which may still cause stress and toxic effects.
Therefore, the development of gene specific replacement therapy is highly challenging, especially when multiple and unknown genes are involved.

Similar to RP, minimal treatment options are available for LCA, which is a group of IRDs characterized by severe impairment of vision or blindness at
birth.  LCA  affects  approximately  15,000  and  18,000  individuals  in  the  United  States  and  Europe,  respectively.  It  is  an  autosomal  recessive  pattern  of
inheritance, wherein both parents, called carriers, have one mutated copy of the gene and one normal gene. They are unaffected carriers of LCA. However,
each of their children has a 25% chance of inheriting the two LCA gene copies (one from each parent) needed to cause the disorder. LCA is caused by a
degeneration and/or dysfunction of photoreceptor rod cells and cone cells in the eye. This affects the processing of electrical signals. The electrical signals
travel from the retina through the optic nerve to the brain. The brain then turns the signals into images that are seen. The less electrical activity there is, the
less sight one will have. Electroretinography is used to measure the electrical signals in the retina. Common symptoms of LCA include a child habitually
pressing their eyes, formations of cataracts, thinning and gradual decline of the cornea which bulges outward into a cone shape. In some cases, the eyes of
individuals  with  LCA  can  appear  sunken.  LCA  is  associated  with  over  25  mutated  genes  and  affects  approximately  160,000  individuals  worldwide.
Luxturna,  developed  by  Spark  Therapeutics,  Inc.,  has  been  approved  by  the  FDA  to  treat  IRDs  caused  by  retinoid  isomerohydrolase  ("RPE65")  gene
mutations. The RPE65 gene represents just one of more than 125 mutated genes linked to RP and LCA. No treatment options have been approved by the
FDA for RP and LCA caused by mutations in other RP and LCA causing genes.

OCU400 for IRDs

OCU400 is our first product candidate being developed with our modifier gene therapy platform. OCU400 has the potential to restore retinal integrity and
function across a range of genetically diverse IRDs. OCU400 consists of a functional copy of the retina-specific NHR gene, NR2E3, delivered to target
cells in the retina using an AAV5 vector that has the potential to be used as a gene therapeutic not only for the treatment of retinal diseases associated with
mutations in genes such as NR2E3, RHO, CEP290, and PDE6ß, but also other gene mutations associated with IRDs, including RP and LCA. As a potent
modifier gene, expression of NR2E3 may help reset retinal cell homeostasis, metabolism, and visual cycle function (Figure 9). OCU400 has received ODD
for NR2E3-related RP and LCA and OMPD from the EC, based on the recommendation of the EMA, for RP and LCA. We believe these broad ODD and
OMPD  designations  demonstrate  that  OCU400  has  the  potential  to  be  a  broad-spectrum  therapeutic  to  treat  multiple  IRDs.  These  ODD  and  OMPD
designations represent gene-agnostic broad coverage for RP and LCA, and are not mutation-specific designations. OCU400 had previously received ODDs
from  the  FDA  for  the  treatment  of  the  following  disease  genotypes:  NR2E3,  RHO,  CEP290,  and  PDE6ß  mutation-associated  inherited  retinal
degenerations.

Figure 9: Mechanism of our modifier gene therapy.

Figure 9 demonstrates the mechanism of our modifier gene therapy. In single-gene replacement therapies such as gene augmentation, only the non-
functional gene is targeted. and accordingly, this therapy cannot improve a multitude of disease-causing genetic defects. In our modifier gene therapy
platform, a functional gene of the retina-specific NHR gene, NR2E3, is introduced to modify the expression of many genes and gene networks and restore
homeostasis.

Table of Contents

As previously described, in five unique mouse models of IRDs, treatment with AAV8-Nr2e3 by subretinal injection rescued multiple genetically diverse
IRDs by protecting photoreceptors from further damage after disease onset. This result demonstrates the potential potency of a novel modifier gene therapy
to elicit broad-spectrum therapeutic benefits in early and advanced stages of IRDs. We are conducting a Phase 1/2 clinical trial, a multicenter, open-label,
dose ranging study to assess the safety of unilateral subretinal administration of OCU400 in patients with NR2E3 and RHO-related RP and CEP290-related
LCA in the United States. We have completed dosing patients with RP in the dose-escalation portion of the clinical trial, which enrolled 10 subjects to
receive a low, medium, or high dose of OCU400 in the subretinal space. We are continuing to enroll subjects with RP and LCA in this clinical trial to
receive the high dose, which was determined to be the maximum tolerable dose from the dose-escalation portion of the clinical trial. We intend to initiate a
Phase 1/2 pediatric clinical trial for OCU400 for the treatment of RP and LCA in the second quarter of 2023 and a Phase 3 clinical trial for OCU400 for the
treatment of RP and LCA near the end of 2023, subject to discussions with the FDA.

Overview of Dry AMD and Stargardt Disease and Current Treatment Options

AMD is attributed to the thinning of the macula of the retina, which leads to impairment and loss of central vision. The macula is the part of the retina
responsible  for  clear  vision  in  one's  direct  line  of  sight.  AMD  is  characterized  by  the  thickening  and  loss  of  normal  architecture  within  the  Bruch's
membrane, lipofuscin accumulation in the RPE, and drusen formation beneath the RPE in the Bruch's membrane. These deposits consist of complement
components,  other  inflammatory  molecules,  lipids,  lipoproteins  B  and  E,  and  glycoproteins.  Common  risk  factors  for  AMD  include  genetics,  smoking,
nutrition and vitamin deficiency, and heart disease. Dry AMD, which affects over 266 million individuals worldwide, involves the slow deterioration of the
retina  with  submacular  drusen  (small  white  or  yellow  dots  on  the  retina),  atrophy,  loss  of  macular  function,  and  central  vision  impairment.  Common
symptoms of dry AMD include visual distortions, reduced central vision in one or both eyes, increased difficulty adapting to low levels of light, and a well-
defined blind spot in one's field of vision.

Similarly,  Stargardt  disease  is  a  rare  genetic  eye  disorder  that  causes  retinal  degeneration  and  ultimately  leads  to  loss  of  central  vision.  It  is  the  most
common form of inherited macular degeneration, affecting approximately 0.8 million individuals worldwide. Stargardt disease happens when lipofuscin, a
fatty  yellow  pigment,  accumulates  on  the  macula,  which  leads  to  the  degeneration  of  the  photoreceptor  cells  in  the  macula  and  ultimately  leads  to
progressive central vision loss. The photoreceptor cells convert light into electrical signals, which are then sent to the brain where they are processed to
create the images we see. Stargardt disease is usually caused by mutations in the ABCA4 gene and is inherited in an autosomal recessive manner. This gene
affects how one's body uses vitamin A. The body uses vitamin A to make cells in the retina. Common symptoms of Stargardt disease include gray, black, or
hazy spots in one's central vision, sensitivity to light, increased time for eyes to adjust between light and dark places, color blindness, and gradual central
vision loss in both eyes. Currently no treatment options exist to address dry AMD or reverse or slow the progression of Stargardt disease and accordingly,
there remains a significant unmet medical need for these ocular diseases.

OCU410 and OCU410ST for the Treatment of Dry AMD and Stargardt Disease

We are developing OCU410 and OCU410ST for the treatment of dry AMD and Stargardt disease, respectively. OCU410 and OCU410ST utilize an AAV
delivery  platform  for  the  retinal  delivery  of  the  RORA  gene.  RORA  regulated  gene  networks  are  relevant  in  the  treatment  of  dry  AMD  and  Stargardt
disease. RORA reduces oxidative stress, limits lipofuscin deposits, reduces chronic inflammation, and improves choroidal blood flow. Gene variants of the
ABCA4  gene  are  associated  with  both  AMD  and  Stargardt  disease.  Stargardt  disease  is  usually  caused  by  mutations  in  the  ABCA4  gene.  This  gene
transports oxidized retinol compounds from photoreceptors to RPE cells for detoxification. In mice models, ABCA4 -/- displayed low levels of CD59. A
cell-surface glycoprotein, CD59, prevents the formation of the complement membrane attack complex. We are currently executing IND-enabling studies
and we intend to submit IND applications in the second quarter of 2023 to initiate Phase 1/2 clinical trials.

NEOCART (AUTOLOGOUS CHONDROCYTE-DERIVED NEOCARTILAGE) CELL THERAPY PLATFORM

We  diversified  our  innovative  pipeline  in  2022  by  introducing  NeoCart  (autologous  chondrocyte-derived  neocartilage),  a  Phase  3-ready,  regenerative
medicine cell therapy technology that combines breakthroughs in bioengineering and cell processing to enhance the autologous cartilage repair process. We
believe NeoCart has the potential to accelerate healing and reduce pain by reconstructing a patient's previously damaged knee cartilage. In May 2022, the
FDA granted an RMAT designation to NeoCart for the repair of full-thickness lesions of knee cartilage injuries in adults.

The  cartilage  is  a  complex  tissue  which  protects  the  various  joints  and  bones  in  the  human  body.  It  acts  as  a  shock  absorber  throughout  the  body
withstanding significant pressure and allowing for joints to glide smoothly with minimal friction. Cartilage damage can be caused by acute trauma, such as
a bad fall or a sports-related injury, or by repetitive trauma, such as general

12

Table of Contents

wear over time. Unlike other tissues in the body, cartilage in the joints has no innate ability to repair itself, making any injury permanent. If left untreated,
even a small defect can expand in size and progress to debilitating OA, ultimately requiring a joint replacement procedure. Over 528 million individuals
worldwide are diagnosed with OA. This number is expected to increase as the population of aging yet active individuals and the rates of obesity increase.

We believe the current therapies available to treat cartilage damage in the knee are suboptimal with varying outcomes due to variable cellular responses.
Chondroplasty  is  often  recommended  in  patients  with  small  cartilage  lesions  (between  one  and  three  cm ).  This  procedure  is  performed  through  small
incisions on the sides of the knee with the aid of an arthroscope. During this procedure, the damaged cartilage is trimmed, and the remaining surface is
smoothed. Microfracture surgery is a frequently used procedure for severe cartilage damage which yields varying outcomes from patient to patient. This
surgery  consists  of  the  creation  of  tiny  holes  or  "fractures"  in  the  bone  underneath  the  injured  cartilage,  leading  to  the  formation  of  a  blood  clot  in  the
affected area. The blood and bone marrow that form the blood clot contain stem cells, which are expected to grow into cartilage-building cells, as well as
growth factors to support cell function and development of replacement cartilage matrix. Approximately 30% of patients that have undergone microfracture
surgery continue to have pain and reduced knee function. Additionally, current therapies require extensive recovery time. They are often ineffective in the
long term as they do not adequately address cartilage damage, which leads to additional corrective surgeries. Autologous culture chondrocytes on porcine
collagen  membrane  (MACI)  is  used  for  the  repair  of  symptomatic,  single,  or  multiple  full-thickness  cartilage  defects  of  the  knee  with  or  without  bone
2
involvement in adults less than 55 years of age. It is a three-by-five centimeter cellular sheet with a density of 500,000 cells per cm .

The  other  options  for  cartilage  repair  include  osteochondral  autograft  transplantation  ("OAT"),  osteochondral  allograft  resurfacing  ("OCA"),  and
autologous chondrocyte implantation ("ACI"). During OAT, damaged cartilage is removed and replaced with healthy cartilage from a non-weight-bearing
area of the joint. OAT is recommended for small to medium sized lesions (between 1.5 and four cm ) and is limited by the amount of donor tissue available,
the  need  for  open  surgery,  and  donor  site  morbidity.  OCA  is  a  similar  process  to  OAT  except  that  the  tissue  is  sourced  from  cadaveric  donor  bone  and
cartilage. OCA is recommended for large lesions (between four and 10 cm ) and can be performed in a single procedure but is limited by the availability of
cadaveric tissue. ACI is a process where cartilage cells are harvested from a non-weight bearing part of the knee and are cultured in a laboratory. They are
subsequently implanted into the injured area.

Over  one  million  arthroscopies  are  performed  annually  as  a  procedure  to  diagnose  and  treat  issues  of  the  joint.  Patients  and  physicians  are  in  need  of
treatment  options  that  offer  more  rapid  and  durable  recovery  compared  to  the  current  treatment  options.  The  attributes  of  an  optimal  treatment  for  a
damaged  knee  cartilage  involve  the  reduction  in  pain,  repair  of  the  knee  cartilage,  rapid  return  to  daily  activities,  durable  response,  and  a  non-opioid
approach. We believe NeoCart would represent a better solution to treat cartilage damage in the knee as it has the potential to solve for the limitations of the
current  therapies  and  has  the  potential  to  provide  improved  efficacy,  long-term  patient  benefits,  accelerated  patient  recovery,  and  predictable  patient
outcomes.

NeoCart is designed to treat pain at the source, improve function, and potentially prevent a patient's progression to OA. NeoCart is a three-dimensional
tissue-engineered  disc  of  new  cartilage  that  is  manufactured  by  growing  chondrocytes,  the  cells  responsible  for  maintaining  cartilage  health.  The
chondrocytes  are  derived  from  the  patient  on  a  unique  scaffold.  In  this  therapy,  the  patient's  cells  are  separated  from  a  tissue  biopsy  specimen  and
multiplied in a manufacturing facility. The cells are then infused into the scaffold, which is a three-dimensional structure that enables the proper delivery,
distribution, and organization of cells in their natural environment to support tissue formation. Before NeoCart is implanted in a patient, the patient's cells
and  the  scaffold  undergo  a  bioengineering  process  in  a  Tissue  Engineering  Processor  ("TEP").  The  TEP  is  designed  to  mimic  the  conditions  inside  a
functional  joint  so  that  the  tissue  is  prepared  to  begin  functioning  like  normal  healthy  cartilage  prior  to  implantation.  Once  NeoCart  is  ready  to  be
implanted, a bioadhesive is used to anchor NeoCart at the site of cartilage injury and seal the implant to the surrounding native cartilage. The bioadhesive is
a natural, biocompatible material which acts as adhesives for biological tissue, thereby eliminating the need for complicated suturing (Figure 10).

Figure 10: Mechanism of the regenerative medicine cell therapy technology, NeoCart.

Figure 10 demonstrates the mechanism of our regenerative medicine cell therapy technology, NeoCart. We believe NeoCart has the potential to accelerate
healing and reduce pain by reconstructing a patient's previously damaged knee cartilage. In this therapy, healthy cartilage tissue is grown and implanted in
the patient.

NeoCart was acquired in our reverse merger in 2019 with Histogenics Corporation ("Histogenics"). Prior to 2019, Phase 1 and Phase 2 clinical trials were
conducted  to  demonstrate  the  safety  and  efficacy  of  NeoCart.  These  clinical  trials  reported  a  decrease  in  pain  and  improved  function  of  the  knee.
Additionally, per the results of the Phase 2 clinical trial, more patients responded to NeoCart than microfracture surgery. No SAEs were reported. A Phase 3
clinical trial was conducted to demonstrate the safety and effectiveness of NeoCart as compared to microfracture surgery to treat cartilage defects in the
knee. This clinical trial enrolled 249 subjects between the ages of 18 and 59. The Phase 3 clinical trial of NeoCart narrowly missed the primary endpoint of
a statistically significant improvement in pain and function in a dual threshold responder analysis one year after the treatment as compared to microfracture
surgery.

We have received concurrence from the FDA on the confirmatory Phase 3 clinical trial design. This study will be a randomized, controlled clinical trial
designed to evaluate the efficacy and safety of NeoCart in comparison to the current standard of care, chondroplasty, in subjects with articular cartilage
defects.  We  intend  to  initiate  the  Phase  3  clinical  trial  in  the  first  half  of  2024,  subject  to  discussions  with  the  FDA.  Our  Phase  3  clinical  trial  will  use
chondroplasty  as  the  control  instead  of  microfracture,  which  was  used  in  the  Phase  3  clinical  trial  conducted  by  Histogenics.  Additionally,  the  Phase  3
clinical trial conducted by Histogenics used a responder analysis for the co-primary endpoint (as opposed to microfracture) that included an improvement
of at least 12 points in outcome compared to baseline at one year on the knee injury and OA outcome score pain assessment test and an improvement of at
least 20 points in outcome compared to baseline on the International Knee Documentation Committee subjective test. In contrast, our Phase 3 clinical trial
will use a co-primary efficacy endpoint defined as the mean change from baseline (as opposed to chondroplasty) to two years for the patients' Knee Injury
and  Osteoarthritis  Outcome  Score  Pain  and  Function  (Activities  of  Daily  Living)  subscale  scales.  Additionally,  the  Phase  3  clinical  trial  conducted  by
Histogenics enrolled patients with a total lesion size of less than six cm , while our Phase 3 clinical trial will enroll patients with total lesion sizes between
2
one to three cm .

VACCINES

We are developing COVAXIN for the prevention of COVID-19 in the Ocugen Covaxin Territory. COVAXIN is a whole-virion inactivated, intramuscular
COVID-19 vaccine candidate that is manufactured using a Vero cell manufacturing platform. COVAXIN was granted an Emergency Use Listing by the
WHO  in  November  2021,  has  been  authorized  or  approved  for  use  in  over  25  countries,  and  is  accepted  for  travel  purposes  in  over  85  countries.
Additionally, COVAXIN has received EUA in India for children ages six to 18 years.

Table of Contents

We  are  also  developing  a  novel  inhaled  mucosal  vaccine  platform,  which  includes  OCU500,  a  bivalent  COVID-19  vaccine;  OCU510,  a  seasonal
quadrivalent  flu  vaccine;  and  OCU520,  a  combination  quadrivalent  seasonal  flu  and  bivalent  COVID-19  vaccine.  OCU510  is  being  developed  for  the
global market.

Overview of COVID-19

COVID-19, caused by the SARS-CoV-2 virus, was first reported to have surfaced in Wuhan, China in December 2019 and was declared a global pandemic
by the WHO in March 2020. COVID-19 is a highly transmissible disease that spreads from person to person through respiratory droplets that are produced
when  an  infected  person  coughs,  sneezes,  or  talks.  In  some  circumstances,  these  respiratory  droplets  may  contaminate  surfaces  they  land  on.  Common
symptoms of COVID-19 include cough, shortness of breath or difficulty breathing, fever or chills, muscle or body aches, sore throat, congestion, or loss of
taste  or  smell.  Certain  people  are  at  an  increased  risk  for  severe  COVID-19  infection  including  those  over  the  age  of  65  and  with  underlying  medical
conditions,  including  cancer,  diabetes,  heart  conditions,  and  obesity,  along  with  many  other  underlying  conditions.  Those  at  increased  risk  for  severe
COVID-19 are more likely to be hospitalized, need intensive care, require a ventilator to help them breathe, or die. Since being discovered, new variants of
SARS-CoV-2  have  emerged.  New  variants  of  a  virus  emerge  when  a  mutation  to  the  virus'  genes  occurs.  SARS-CoV-2  and  its  variants  have  caused
approximately over 756.5 million cases of COVID-19 and 6.8 million deaths, with the United States alone accounting for over 101.4 million cases and 1.1
million deaths. The Omicron variant (B.1.1.529) was identified in November 2021 and has continued to be deemed a variant of concern by the WHO due to
at  least  one  of  the  following  characteristics:  increase  in  transmissibility  or  detrimental  change  in  COVID-19  epidemiology,  an  increase  in  virulence  or
change  in  clinical  disease  presentation,  or  a  decrease  in  effectiveness  of  public  health  and  social  measures  or  available  diagnostics,  vaccines,  or
therapeutics. Since being identified, several sub-variants of the Omicron variant (B.1.1.529) have been observed as the virus circulated at intense levels
worldwide. Research suggests that the Omicron variant (B.1.1.529) is more contagious and increases the risk of reinfection when compared to variants that
were previously deemed to be variants of concern.

COVAXIN for the Prevention of COVID-19

COVAXIN is formulated with the inactivated SARS-CoV-2 virus, an antigen, and an adjuvant, which is a common approach to vaccine design. COVAXIN
is  designed  to  utilize  the  whole-virion  inactivated  SARS-CoV-2  virus  to  trigger  the  immune  response  to  create  antibodies  against  multiple  antigens.
Inactivated  vaccines  do  not  replicate  and  are  therefore  unlikely  to  revert  and  cause  pathological  effects.  COVAXIN  has  an  antigen  concentration  of  six
micrograms  and  utilizes  a  toll-like  receptor  ("TLR")7/8  agonist  molecule,  IMDG  adsorbed  to  alum  (Algel)  as  adjuvants  which  generates  a  Th1-biased
immune response (cell-mediated immunity) that induces high neutralization efficacy against different variants and robust long-term memory B cell and T
cell responses. The adjuvant used in the formulation of COVAXIN was developed in the United States with funding from the National Institutes of Health
("NIH") and is the first adjuvant in an authorized or approved vaccine against an infectious disease to activate TLR7/8. The alum in the adjuvant stimulates
the immune system to search for an invading pathogen. Molecules that activate TLR7/8 provide a powerful stimulation of the immune system. COVAXIN
is intended for administration into the deltoid muscle of the upper arm, in two doses occurring 28 days apart, and has an expected shelf life of 24 months
from the date of manufacture at 2-8°C and a six-month stability at room temperature (25°C).

The rise of COVID-19 genetic variants has raised concerns that these variants may be able to escape neutralization by vaccines. The data from clinical
trials  conducted  in  India  suggest  that  COVAXIN  elicits  a  broad-spectrum  immune  response  (including  S  and  nucleocapsid  proteins)  and  induces  both
humoral and cellular responses. In addition, COVAXIN is designed to generate memory B cell and T cell responses for its multiple epitopes, potentially
indicating longevity of response and a rapid antibody response to future infections. Furthermore, data suggests that COVAXIN may potentially generate
robust immune memory to SARS-CoV-2 and certain of its variants, including the Omicron variant (B.1.1.529), for at least six months after vaccination. We
believe COVAXIN has certain characteristics that may be beneficial as compared to other currently authorized or approved messenger RNA ("mRNA"),
adenovirus-based vaccines, and protein subunit vaccines. COVAXIN represents an important additional vaccine option for individuals who are looking for
a well-established approach to vaccine development and manufacturing.

The inactivated SARS-CoV-2 virus in COVAXIN is inactivated using β-propiolactone treatment at a low temperature. As an inactivated virus vaccine, we
believe COVAXIN can use all the proteins in the virus to elicit an immune response, rather than targeting the S protein alone, which is a characteristic of
the mRNA and adenovirus-based vaccines. We believe an inactivated whole-virion vaccine can produce a more robust response that can elicit memory and
cross-react with mutated strains. We believe that, once vaccinated with COVAXIN, the immune system can respond to a live infection of SARS-CoV-2.

Bharat Biotech Clinical Trials

Phase 1 and Phase 2 clinical trials were conducted by Bharat Biotech in India to evaluate the safety and immunogenicity of COVAXIN. These clinical trials
reported  a  favorable  safety  profile  and  strong  Immunoglobulin  G  ("IgG")  responses  against  the  S  protein,  the  receptor-binding  domain,  and  the
nucleocapsid protein of SARS-CoV-2 along with strong cellular responses. Strong cellular responses are necessary for memory and long-term durability of
vaccines. No SAEs were reported in these clinical trials.

A  Phase  3,  randomized,  placebo-controlled  clinical  trial  was  conducted  by  Bharat  Biotech  in  India  to  evaluate  the  efficacy  of  COVAXIN.  The  Phase  3
clinical trial enrolled 25,798 adults, ages 18 years and older, who were healthy or had stable chronic medical conditions, including 10.7% of participants
over  the  age  of  60  and  27.5%  of  participants  with  at  least  one  coexisting  condition,  including  cardio-vascular,  diabetes,  or  any  other  chronic  stable
condition.  Participants  with  no  serological  evidence  of  previous  exposure  to  SARS-CoV-2  received  two  doses  of  either  COVAXIN  or  the  placebo
administered four weeks apart. The Phase 3 clinical trial reported an overall estimated vaccine efficacy of COVAXIN against COVID-19 of 77.8%, with
efficacy  against  severe  COVID-19  of  93.4%,  and  efficacy  against  asymptomatic  COVID-19  of  63.6%.  Individuals  with  asymptomatic  infection  have  a
detectable viral load in nasal and saliva swabs and therefore are considered carriers of COVID-19. Cross variant protection was also demonstrated with a
vaccine efficacy of 65.2% against the Delta variant (B.1.617.2). The aforementioned efficacy results represent point estimates of vaccine efficacy with a
95% confidence interval ("CI"), which is above the success criteria of 50%. Adverse events in the COVAXIN and control arms of the Phase 3 clinical trial
were observed in 12.4% of subjects, with less than 0.5% of subjects experiencing SAEs. Data from the clinical trials and from research conducted by third
parties  has  shown  that  COVAXIN  has  neutralizing  potential  against  multiple  variants,  including  the  Omicron  (B.1.1.529)  variant,  which  is  a  variant  of
concern. Further, recent studies have shown that individuals receiving a COVAXIN booster dose six months following the second dose of COVAXIN saw a
significant increase in neutralizing titers, an important predictor of vaccine efficacy. The increase in neutralizing titers was higher than that achieved after
the primary two-dose series.

A Phase 2/3 immuno-bridging clinical trial was conducted by Bharat Biotech in India to assess the immunity of COVAXIN in children ages two to 18
years. COVAXIN is formulated such that the same dosage can be administered to adults and children alike. The results demonstrated a robust neutralizing
antibody  response  comparable  to  that  of  the  adults  studied  in  the  Phase  2  clinical  trial  conducted  by  Bharat  Biotech  in  India,  and  that  COVAXIN  was
generally well tolerated. Among the 526 study subjects in the Phase 2/3 pediatric clinical trial, no SAEs were reported.

Regulatory Pathway in the Ocugen Covaxin Territory

In  January  2023,  we  announced  top-line  results  from  our  Phase  2/3  immuno-bridging  and  broadening  clinical  trial  in  the  United  States  evaluating
COVAXIN for adults ages 18 years and older. The clinical trial was designed to evaluate whether the immune response observed in participants in Bharat
Biotech's completed Phase 3 clinical trial in India is similar to a demographically representative, adult population in the United States. The clinical trial
enrolled  419  adult  participants  that  were  randomized  to  receive  either  two  doses  of  COVAXIN  or  a  placebo,  28  days  apart.  Immune  responses  were
adjusted  for  differences  between  the  U.S.  and  Indian  cohorts  in  baseline  neutralizing  antibody,  body  mass  index,  gender,  and  age.  Both  co-primary
immunogenicity  endpoints  were  met,  with  the  95%  CI  for  the  propensity  score-adjusted  geometric  mean  titer  ratio  being  well  above  the  non-inferiority
limit of 0.667. The 95% CI for the propensity score-adjusted difference in seroconversion rates were well above the non-inferiority limit of (10)%. There
were no deaths, related potential immune mediated medical conditions, or related adverse events of special interest. Additionally, there were no cases of
myocarditis, pericarditis, thrombotic events, or Guillain-Barré syndrome. There were no cases of adverse events and SAEs related to the vaccination. 30
medically attended adverse events in 18 subjects and two SAEs in one subject were reported, all of which were considered unrelated to the vaccination. We
plan to work with government agencies in the United States to obtain funding in order to comply with the requirements of a BLA submission, including
funding to initiate an adult safety clinical trial subject to discussions with the FDA.

We  also  have  rights  to  commercialize  COVAXIN  in  Canada  and  Mexico.  In  July  2021,  we  completed  our  rolling  submission  to  Health  Canada  for
COVAXIN. The rolling submission process, which was conducted through our Canadian subsidiary, Vaccigen, was recommended and accepted under the
Minister of Health's Interim Order and transitioned to a NDS for COVID-19. In August 2022, we withdrew our NDS based on discussions with Health
Canada and are evaluating the requirements for resubmitting an updated NDS. In Mexico, the COFEPRIS authorized emergency use for COVAXIN for
adults ages 18 years and older, which remains active. We are in discussions with CONACYT in Mexico regarding our submission for EUA for COVAXIN
for pediatric use in ages five to 18 years.

Overview of the Seasonal Flu

The seasonal flu, or seasonal influenza, is an acute respiratory infection caused by influenza viruses circulating globally. In temperate climates, seasonal
epidemics  occur  mainly  during  the  winter,  while  in  other  regions,  transmission  may  occur  throughout  the  year,  causing  outbreaks  more  irregularly.  The
seasonal  flu  causes  illnesses  that  range  in  severity  and  may  lead  to  hospitalization  and  death  in  certain  cases.  The  seasonal  flu  is  characterized  by  the
sudden  onset  of  the  following:  fever,  dry  cough  (typically),  headache,  muscle  and  joint  pain,  severe  malaise,  sore  throat,  and  runny  nose.  Most  people
infected with the seasonal flu recover from the fever and other symptoms within a week without requiring medical attention, but the cough can be more
severe and last two weeks or more. Although most people recover quickly from the seasonal flu, severe illness and death can occur particularly among high
risk groups including children, the elderly, pregnant women, health care workers, and those with serious underlying medical conditions. Worldwide, the
seasonal flu is estimated to result in 3 to 5 million cases of severe illness, and 0.3 million to 0.7 million respiratory deaths.

The  seasonal  flu  spreads  easily  and  rapidly  transmits  in  crowded  areas.  The  seasonal  flu  is  transmitted  when  an  infected  person  coughs  or  sneezes  and
droplets containing the virus are dispersed into the air and infects those in close proximity that breathe the droplets in. The seasonal flu can also spread
through  physical  contact,  although  this  type  of  transmission  is  less  common  than  airborne  transmission.  Those  infected  with  the  seasonal  flu  are  most
contagious within the first three to four days of infection. Transmission may begin one day before symptoms develop and may continue for five to seven
days after symptoms develop. The flu is most commonly prevented by getting an annual flu vaccine and taking preventative actions to avoid transmission
such as staying away from those who are sick, frequent handwashing, and covering coughs and sneezes. For the 2022 to 2023 flu season, over 50% of the
U.S. population above six months of age has received a seasonal flu shot with over 170 million doses being administered. Several flu antiviral drugs are
also available in different dosage forms to treat the seasonal flu, including pills, liquid, an inhaled powder, or an intravenous solution. These flu antiviral
drugs are only available through a prescription from a healthcare provider and are not sold over the counter.

Novel Inhaled Mucosal Vaccine Platform for the Prevention of COVID-19 and the Seasonal Flu

We are developing a novel inhaled mucosal vaccine platform, which includes OCU500, a bivalent COVID-19 vaccine; OCU510, a seasonal quadrivalent
flu vaccine; and OCU520, a combination quadrivalent seasonal flu and bivalent COVID-19 vaccine. OCU510 is being developed for the global market.

Our  novel  inhaled  mucosal  vaccine  platform  is  specifically  designed  to  generate  local  mucosal  immunity  in  the  nasopharyngeal  region.  The  mucosal
vaccination  method  has  demonstrated  potent  induction  of  both  mucosal  and  systemic  immune  responses,  which  prevents  infection  and  spread,  thereby
limiting the origins of new variants. We believe our novel inhaled mucosal vaccine platform is unique as it is designed to induce mucosal immunity, which
is crucial for preventing upper respiratory tract infection, as compared to intramuscular vaccines. The advantages of these inhaled mucosal vaccines include
needle-free administration, the potential for increased compliance, scalable manufacturing, storage and shipping at standard refrigerated conditions, and the
potential to develop multi-strain and variant-specific versions. As these vaccine candidates are being developed to be administered through inhalation, we
believe our novel inhaled mucosal vaccine platform has the potential to generate rapid local immunity in the upper airways and lungs where viruses enter
and infect the body, which we believe may help reduce or prevent infection and transmission as well as provide protection against new virus variants.

The S protein of SARS-CoV-2 is the principal target for antibody-based and vaccine countermeasures. The S protein serves as the primary viral attachment
and entry factor to promote SARS-CoV-2 entry into human cells. In preclinical studies that have been conducted to assess the durability, dose response, and
cross-protective activity in mice, it was demonstrated that a single dose of our inhaled mucosal COVID-19 vaccine induced durably high neutralizing and
antibody  effector  responses  in  serum  and  S  protein  specific  IgG  and  Immunoglobulin  A,  which  is  essential  for  reducing  infection  and  transmission  of
COVID-19. This approach represents a potential universal booster, regardless of previous COVID-19 vaccination. OCU520, our combination quadrivalent
seasonal flu and bivalent COVID-19 vaccine, is designed to provide the unique ease of getting both an annual COVID-19 booster vaccine and an annual
seasonal flu vaccine in one vaccine.

Pursuant to the WU License Agreement, we obtained the rights to develop, manufacture, and commercialize an inhaled mucosal COVID-19 vaccine in the
Mucosal Vaccine Territory. We are developing the seasonal flu component of this inhaled mucosal vaccine platform internally. We intend to initiate IND-
enabling studies and work closely with government agencies to obtain funding for the development of these inhaled mucosal vaccines.

NOVEL BIOLOGIC PRODUCT CANDIDATE FOR RETINAL DISEASES

We are developing OCU200, which is a novel fusion protein containing parts of human tumstatin and transferrin. OCU200 is designed to treat DME, DR,
and wet AMD. We have completed the technology transfer of manufacturing processes to our CDMO and have produced clinical trial materials to initiate a
Phase 1 clinical trial. We submitted an IND application to the FDA in February 2023 to initiate a Phase 1 clinical trial targeting DME. The planned Phase 1
clinical study will assess the unilateral intravitreal administration of OCU200 alone or in combination with an approved anti-VEGF therapy in participants
with  DME.  This  is  a  multicenter,  open-label,  dose  ranging  study  with  three  cohorts  in  the  dose-escalation  portion  of  the  study  and  one  cohort  in  the
combination therapy portion of the study.

Overview of DR and DME

DR is a sight-threatening complication of diabetes arising from the over-accumulation of glucose, which can block blood vessels in the retina and cut off
blood supply, leading to the damage of blood vessels in the retina. DR is classified into two subtypes: non-proliferative DR and proliferative DR. Non-
proliferative DR is the early stage of DR wherein blood vessels are unable to grow, blood vessel walls weaken, and nerve fibers in the retina may swell.
Proliferative DR is the advanced stage of DR in which damaged blood vessels close off, leading to the growth of new, abnormal blood vessels in the retina.
This growth of new, abnormal blood vessels in the retina can lead to scar tissue, which can result in the detachment of the retina from the back of the eye.

Complications from DR could lead to DME. In DME, bulges can protrude from the blood vessel walls, leading to the leakage of fluid and blood into the
retina. This leakage results in swelling, or "edema," in the macula, which is a part of the retina. DME may occur at any stage of DR but is more likely to
occur as the disease progresses. DME is the most common reason for vision loss in patients with DR.

DR and DME are the most common vision-threatening diseases in patients with diabetes. Approximately 162 million individuals are affected with DR and
approximately 21 million with DME worldwide. As the population of people experiencing diabetes increases, these statistics are expected to increase, due
to poor disease management and lifestyle-related changes. There are limited treatment options available for patients with DR and DME. Current first-line
treatments  for  DR  and  DME  include  the  use  of  anti-vascular  endothelial  growth  factor  ("VEGF")  therapy  and  anti-inflammatory  therapy,  such  as
corticosteroids.  These  treatments  do  not  work  effectively  in  approximately  50%  of  patients  with  DME.  There  is  a  significant  need  to  develop  a  novel,
differentiated therapeutic to treat DR and DME.

Additionally, current therapies target only one pathway associated with DR and DME, either angiogenesis (development of new blood vessels) with anti-
VEGF  therapy,  such  as  Ranibizumab  or  Aflibercept,  or  inflammation  in  case  of  corticosteroid  therapy,  such  as  Dexamethasone  or  Fluocinolone.  The
development of a therapeutic which targets multiple causative pathways of DR and DME, such as angiogenesis, oxidation, and inflammation, would offer a
potential treatment option for all patients. We believe that OCU200 possesses unique characteristics to target these pathways and has the potential to offer
better treatment options for all patients with DR and DME.

Overview of Wet AMD

OCU200 also has the potential to represent a better treatment option for patients suffering from wet AMD. Most AMD cases begin as dry AMD and may
progress towards the advanced "wet" form. Wet AMD is caused by abnormal blood vessels in the retina that leak fluid or blood into the macula. The result
can be irreversible damage to photoreceptor cells and rapid, severe vision loss, particularly in the center of the field of vision, causing significant functional
impairment.  If  left  untreated,  neovascularization  in  wet  AMD  patients  typically  results  in  significant  vision  loss  and  the  formation  of  a  scar  under  the
macula. Wet AMD affects approximately 10-15% of patients with AMD but progresses more rapidly and is known to be responsible for approximately
90% of all AMD-related blindness.

AMD is a leading cause of blindness worldwide. The incidence of wet AMD increases substantially with age, and it is expected that the number of cases of
wet AMD will increase with the growth of the elderly population. It has been estimated that approximately 296 million individuals worldwide have some
form of AMD of which, approximately 30 million, or 10%, suffer from wet AMD.

Current  FDA  approved  therapeutics  for  wet  AMD  include  intravitreal  injection  of  either  Ranibizumab  or  Aflibercept,  which  are  anti-VEGF  therapies.
Though  treatments  have  been  effective  in  mitigating  the  disease  symptoms,  clinical  studies  suggest  substantial  limitations  remain.  For  example,  a
significant percentage of people do not respond to therapy and experience continuous deterioration of their vision. Additionally, the repeated use of anti-
VEGF therapy becomes less effective over time.

18

Table of Contents

Between 30-50% of people affected by wet AMD continue to have fluid remain in the middle of the eye, also called the subretinal space, even after one to
two years of treatment.

Given the above limitations of these existing treatments, we believe that a substantial unmet medical need exists for the treatment of DR, DME, and wet
AMD.

OCU200 for the Treatment of DR, DME, and Wet AMD

OCU200 is a novel fusion protein containing parts of human tumstatin and transferrin, that are already present normally in retinal tissues. Patients affected
by these diseases share common symptoms, such as blurriness in vision and continued vision loss through disease progression. The formation of fragile and
leaky new abnormal blood vessels leads to fluid accumulation in and around the retina, causing vision damage.

We believe OCU200 possesses unique features and is designed to enable it to efficiently target leaky blood vessels, regress the existing abnormal blood
vessels,  and  inhibit  the  growth  of  new  blood  vessels  in  the  retina  and  choroid.  Tumstatin,  which  acts  as  an  anti-VEGF,  anti-inflammatory,  and  anti-
oxidative agent, is the active component of OCU200. It binds to integrin receptors, which play a crucial role in disease pathogenesis. Transferrin is an iron
carrier that delivers iron intracellularly. It enhances the delivery of fused proteins across cellular barriers, including retinal barriers. It allows the targeting of
anti-angiogenic  peptide  to  the  multiplying  endothelial  cells.  OCU200  is  designed  to  address  the  limitations  of  current  therapies  by  targeting  multiple
mechanisms associated with ocular neovascularization and inflammation specifically focusing on non-responders to currently available treatment options.

A  proof-of-concept  study  involving  different  animal  models  demonstrated  the  therapeutic  potential  of  OCU200  in  the  treatment  of  DR,  DME,  and  wet
AMD. In an animal model for DME and DR (oxygen-induced retinopathy in mice), OCU200, at a significantly lower dose (10 micrograms per eye), was
comparable to existing approved anti-VEGF therapy (Eylea, 20 micrograms per eye) in preventing disease manifestation and progression. In animal models
for wet AMD (laser induced choroidal neovascularization in mice and rats), OCU200 demonstrated comparable or slightly better activity compared to anti-
VEGF control groups in preventing the formation and growth of new leaky blood vessels and subsequent disease symptoms. We believe OCU200's distinct
mechanism of action through the target of the integrin pathway will potentially provide benefit to patients, particularly to those patients that do not respond
to currently approved therapies.

COMPETITION

The biotechnology industry is characterized by rapidly advancing technologies as well as a strong emphasis on intellectual property leading to a highly
competitive environment for the development and commercialization of therapeutic products, regenerative medicines, and vaccines. We face competition
with  respect  to  our  current  product  candidates  and  will  face  competition  with  respect  to  any  product  candidates  that  we  may  seek  to  develop  or
commercialize in the future. We face competition from many different sources, including from major pharmaceutical companies, specialty pharmaceutical
companies,  biotechnology  companies,  academic  institutions,  government  agencies,  and  other  public  and  private  research  organizations  that  conduct
research, seek patent protection, and establish collaborative arrangements for research, development, manufacturing, and commercialization. We plan to
compete in the segments of pharmaceutical, biotechnological, and other related markets with therapeutics, regenerative medicines, and vaccines that have
an acceptable safety profile and target commercially attractive indications.

The development and commercialization of gene therapies is highly competitive. We are aware of several companies focusing on gene therapies for various
ophthalmic indications including Applied Genetic Technologies Corporation, as acquired by Syncona Limited, Astellas Pharma Inc., MeiraGTx Holdings
plc in partnership with Janssen Pharmaceuticals, Inc., Nanoscope Therapeutics Inc., REGENXBIO Inc., Novartis AG, F. Hoffmann-La Roche AG ("Roche
AG"),  Kiora  Pharmaceuticals,  Inc.,  Genentech,  Inc.  in  partnership  with  Lineage  Cell  Therapeutics,  Inc.,  and  Luxturna,  the  product  developed  by  Spark
Therapeutics,  Inc.  and  marketed  by  Roche  AG,  is  currently  the  only  gene  therapy  approved  to  treat  IRDs  in  the  United  States  which  addresses  only
mutations in the RPE65 gene. The mutation associated with the RPE65 gene represents just one of more than 125 mutated genes linked to RP and LCA.

The regenerative medicine sector is characterized by innovative science, rapidly advancing technologies, and a strong emphasis on proprietary products.
The  competitive  landscape  in  the  field  of  articular  cartilage  repair  in  the  U.S.  is  emerging  and  has  stimulated  a  substantial  amount  of  interest  from
companies developing tissue repair solutions. Companies that may compete with our NeoCart product candidate include Vericel Corporation's MACI, the
only FDA-approved ACI product in the United States, and Aesculap Biologics, LLC's NOVOCART 3D, which is currently enrolling subjects in their Phase
3 clinical trial.

We  face,  and  will  continue  to  face,  intense  competition  from  companies  as  well  as  institutions  that  are  pursuing  or  have  commercialized  vaccines  that
would compete with our vaccine candidates, COVAXIN and our novel inhaled mucosal vaccine platform, if commercialized. The competitive landscape of
COVID-19 vaccines has been rapidly developing since the beginning of the COVID-19 pandemic and includes competitors such as Pfizer Inc./BioNTech
SE, Moderna, Inc., AstraZeneca PLC, Novavax, Inc., Sinovac Biotech Ltd., Gamaleya Research Institute of Epidemiology and Microbiology, and Center
for  Genetic  Engineering  and  Biotechnology.  Each  of  the  aforementioned  vaccines  have  been  authorized  or  approved  in  at  least  one  country  within  the
Ocugen  COVAXIN  Territory  or  the  Mucosal  Vaccine  Territory  and  are  intramuscular  vaccines.  CanSinoBIO's  Convidecia  Air,  an  intranasal  vaccine
targeting  COVID-19,  has  been  approved  in  China.  Other  competitors  for  our  novel  inhaled  mucosal  vaccine  platform  include  CyanVac  LLC,  Meissa
Vaccines, Inc., Codagenix, Inc., Intravacc B.V., McMaster University, and Tetherex Pharmaceuticals Corporation. Companies such as Pfizer Inc./BioNTech
SE,  Moderna,  Inc.,  CureVac  N.V  in  partnership  with  GSK  plc,  Vivaldi  Biosciences  Inc.,  and  Novavax,  Inc.  are  also  in  the  process  of  developing  a
combination vaccine that will protect against COVID-19 and the seasonal flu. Vivaldi Biosciences Inc. is also currently undergoing clinical trials for their
intranasal vaccine for the seasonal flu.

The  development  and  commercialization  of  biologic  products  is  highly  competitive  as  well.  Companies  that  may  compete  with  our  OCU200  product
candidate include Roche AG, Regeneron Pharmaceuticals, Inc., AsclepiX Therapeutics, Inc., Outlook Therapeutics, Inc., Novartis AG, Oxurion NV, Unity
Biotechnology, Inc., Opthea Limited, and 4D Molecular Therapeutics, Inc. Roche AG, Regeneron Pharmaceuticals, Inc., and Novartis AG have marketed
anti-VEGF products.

Many of our competitors, either alone or with strategic partners, may have significantly greater financial resources to support research and development,
manufacturing,  preclinical  studies,  and  clinical  trials,  as  well  as  regulatory,  commercialization,  and  marketing  efforts.  These  organizations  also  compete
with  us  in  recruiting  and  retaining  qualified  scientific  and  management  personnel,  establishing  clinical  trial  sites,  patient  registration  for  clinical  trials,
licensing or acquiring technologies necessary for our programs, and in our commercialization efforts if our product candidates are approved. Early-stage
companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. Mergers
and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our
competitors.

MANUFACTURING AND SUPPLY

We utilize our in-house expertise and know-how as well as the expertise and know-how of our industry leading manufacturing partners to develop and
scale  up  our  manufacturing  processes  for  both  the  clinical  and  commercial  supply  of  our  product  candidates.  We  collaborate  with  our  manufacturing
partners to understand and establish controls for critical process parameters and critical quality attributes. Our in-house expertise includes personnel with
extensive product development and commercialization experience who actively manage our manufacturing partners that produce products in our product
candidate pipeline. Our current manufacturing partners, including CanSinoBIO, Bharat Biotech, and Jubilant HollisterStier, have state-of-the-art facilities
with significant expertise in biotechnology manufacturing.

Clinical Supply of Our Modifier Gene Therapy Platform

We have a co-development and commercialization agreement with CanSinoBIO with respect to the development and commercialization of our modifier
gene  therapy  platform.  The  CanSinoBIO  Agreement  was  originally  entered  into  in  September  2019  with  respect  to  OCU400  and  was  subsequently
amended in September 2021 and November 2022 to include OCU410 and OCU410ST, respectively, in addition to OCU400. Pursuant to the CanSinoBIO
Agreement, we are collaborating with CanSinoBIO on the development of our modifier gene therapy platform. CanSinoBIO is responsible for the CMC
development and manufacture of clinical supplies of such product candidates and is responsible for the costs associated with such activities. CanSinoBIO
has an exclusive license to develop, manufacture, and commercialize our modifier gene therapy platform in and for China, Hong Kong, Macau, and Taiwan
(the  "CanSinoBIO  Territory"),  and  we  maintain  exclusive  development,  manufacturing,  and  commercialization  rights  with  respect  to  our  modifier  gene
therapy platform outside the CanSinoBIO Territory (the "Company Territory").

We partner with CanSinoBIO for the process development, manufacturing, testing, and release of drug product candidates for use in IND-enabling studies
and  clinical  trials.  We  perform  discovery  and  analytical  development  activities  in  our  research  and  development  lab.  The  partnership  with  CanSinoBIO
enables us in completing manufacturing, with release of clinical trial materials in an expedited manner and helps in mitigating the risk of delay that can be
associated when working with highly competitive CDMOs that have long wait times with regard to gene therapy manufacturing. Although we rely on our
partnership for manufacturing, we have personnel with extensive experience in gene therapy manufacturing to oversee and guide the process and analytical
development, scale-up, release, and stability testing at our partner site. We perform periodic audits of our manufacturing partner to confirm compliance
with applicable regulations.

3 clinical trial material, which we anticipate will be completed in the fourth quarter of 2023.

Clinical and Commercial Supply of COVAXIN

Pursuant  to  the  Covaxin  Agreement  with  Bharat  Biotech,  we  obtained  an  exclusive  right  and  license  to  develop,  manufacture,  and  commercialize
COVAXIN for the Ocugen Covaxin Territory. In accordance with the Covaxin Agreement, Bharat Biotech agreed to provide us with preclinical and clinical
data and transfer to us certain proprietary technology owned or controlled by Bharat Biotech that is necessary for the commercial manufacture and supply
of  COVAXIN  to  support  its  commercial  sale  in  the  Ocugen  Covaxin  Territory,  if  approved.  We  also  selected  Jubilant  HollisterStier  as  a  manufacturing
partner to prepare for the commercial manufacturing of COVAXIN.

Additionally, we entered into the Supply Agreement with Bharat Biotech pursuant to which Bharat Biotech will supply us with clinical trial materials and
commercial  supplies  of  COVAXIN  finished  drug  product  prior  to  the  completion  of  a  technology  transfer.  Following  the  completion  of  the  initiated
technology  transfer  to  Jubilant  HollisterStier,  Bharat  Biotech  will  supply  COVAXIN  drug  product  components  and  continue  to  supply  finished  drug
product as necessary for the commercial manufacture and supply of COVAXIN. The WHO identified certain GMP deficiencies in an inspection of Bharat
Biotech's facilities and Bharat Biotech is currently responding to these deficiencies in order to meet the required GMP standards in the Ocugen Covaxin
Territory.

For  more  information  about  our  partnership  with  Bharat  Biotech,  see  "—License  and  Development  Agreements—Co-Development,  Supply  and
Commercialization Agreement with Bharat Biotech" and see Note 3 in our notes to the consolidated financial statements included elsewhere in this Annual

NeoCart

License Agreement with Purpose

In December 2005, Histogenics entered into an exclusive agreement (the "Purpose Agreement") to sublicense certain technology from Purpose, which we
assumed  as  a  result  of  our  reverse  merger  with  Histogenics.  Purpose  entered  into  the  original  license  agreement  ("BWH-Purpose  Agreement")  with
Brigham and Women’s Hospital, Inc. ("BWH") in August 2001. The BWH-Purpose Agreement granted Purpose an exclusive, royalty-bearing, worldwide,
sublicensable license, under its rights in licensed patents and patent applications co-owned by BWH and Purpose to make, use, and sell (1) an apparatus for
cultivating a cell or tissue, (2) cell or tissue products made using such apparatus, (3) cell or tissue products made using processes for cultivating a cell or
tissue as disclosed in the licensed patents and patent applications, and (4) any apparatus that cultivates cells or tissues using such processes, in each case,
whose  manufacture,  use,  or  sale  is  covered  by  a  valid  claim  of  the  licensed  patents  and  patent  applications,  only  for  therapeutic  use.  Pursuant  to  our
sublicense from Purpose, we are obligated to pay minimum royalties and low single digit royalties based on the net sales of licensed products, milestone
payments,  and  sublicense  payments  due  on  the  BWH-Purpose  Agreement.  Histogenics  paid  an  aggregate  of  $1.0  million  in  minimum  royalty  and
sublicense payments under the terms of the Purpose Agreement prior to the reverse merger.

22

Table of Contents

The Purpose Agreement was amended and restated in June 2012, pursuant to which Purpose granted Histogenics outside of Japan: (a) exclusive rights to all
of Purpose's technology (owned or licensed) related to the exogenous tissue processors, which is used in the development of NeoCart, (b) continued supply
of  exogenous  tissue  processors,  and  (c)  rights  to  manufacture  the  exogenous  tissue  processors  at  any  location  we  choose.  In  exchange  for  such
consideration, Purpose was granted an exclusive license in Japan for the use of all of our NeoCart technology and was reimbursed for development costs on
a  multi-unit  exogenous  tissue  processor.  In  May  2016,  the  Purpose  Agreement  was  amended,  whereby  Histogenics  reacquired  the  development  and
commercialization rights to NeoCart in Japan.

The Purpose Agreement, as amended, provides us with the ability, worldwide, to (i) use, make, have made, sell, offer for sale, import or otherwise exploit
products  or  services  covered  by  claims  of  Purpose's  patents  and  (ii)  use,  reproduce,  modify,  create  derivative  works  of  and  otherwise  exploit  Purpose’s
technology for the design, development, manufacture, testing, support, and commercialization of any product or service that incorporates or builds upon
Purpose’s technology, in each case, only in connection with articular cartilage, ligaments, tendons, and meniscus. Purpose retains the right to sell its single
unit exogenous tissue processer machines to research institutes for general but noncommercial use anywhere in the world.

Under the Purpose Agreement, we are obligated to pay Purpose up to $10.0 million upon the achievement of certain regulatory and commercial milestones
as well as a royalty payment in the low single digits on the net sales in Japan of NeoCart. Such royalty payment shall be reduced to the extent NeoCart does
not rely on an outstanding Purpose patent.

The BWH-Purpose Agreement remains in effect for the life of the licensed patents. The BWH-Purpose Agreement may be terminated if BWH is provided
written notice at least 60 days in advance. BWH has the right to terminate the agreement if minimum royalty payments or other payments fail to be made or
otherwise the BWH-Purpose Agreement is breached and such breach is not cured within 30 days of BWH providing notice. Upon the termination of the
BWH-Purpose  Agreement,  our  sublicense  will  convert  to  a  nonexclusive  license  to  only  Purpose's  interest  in  the  licensed  products  or  processes.  Upon
written notice to Purpose of our intent to stop using the technology sublicensed to us in the BWH-Purpose license, Purpose will reassume all responsibility
under the BWH-Purpose license or at Purpose’s option, allow the license to lapse.

INTELLECTUAL PROPERTY

Our  success  depends  in  part  upon  our  ability  to  protect  our  core  technologies  and  intellectual  products.  We  have  applied,  obtained,  and  licensed  patent
protection for our product candidates. We intend to maintain and defend our intellectual property rights to protect our technology, inventions, processes,
and improvements that are commercially important to the development of our business. There is no guarantee that any of our current or future intellectual
property will advance the commercial success of our product candidates. There is also no guarantee patents will be issued or registered for any pending
patent  applications  or  patent  applications  that  we  may  file  in  the  future.  Our  commercial  success  also  depends  in  part  on  our  non-infringement  of  the
patents and proprietary rights of third parties.

As of February 15, 2023, our patent portfolio for our product candidates included a total of 24 issued patents in the United States, 63 issued or registered
patents in foreign countries, nine pending patent applications in the United States, and 14 pending patent applications in foreign countries. Our issued or
registered patents and pending patent applications include those licensed from SERI, Purpose Co, Washington University, and CU. Certain issued patents
and  pending  patent  applications  cover  multiple  of  our  product  candidates.  Our  intellectual  property  includes  compositions  of  matter,  methods  of  use,
product candidates, and other proprietary technology. As of February 15, 2023, we had exclusive rights or owned rights to: (i) two issued U.S. patents, one
pending  U.S.  patent  application,  and  three  pending  foreign  patent  applications  related  to  OCU400;  (ii)  one  issued  U.S.  patent,  one  pending  U.S.  patent
application,  and  three  pending  foreign  patent  applications  related  to  OCU410  and  OCU410ST;  (iii)  21  issued  U.S.  patents;  four  pending  U.S.  patent

application, 25 issued or registered foreign patents, and four pending foreign patent applications related to OCU200. Our current portfolio of issued patents
in the U.S. and issued or registered patents in foreign countries related to our product candidates expire between 2024 and 2038.

Pursuant to the Covaxin Agreement which was originally entered into in February 2021, we obtained an exclusive right and license under certain of Bharat
Biotech's intellectual property rights with the right to grant sublicenses, to develop, manufacture, and commercialize COVAXIN in the United States, its
territories, and possessions, Canada, and Mexico.

In some instances, we may need to license additional patents and trade secrets to commercialize our product candidates in certain territories. In addition to
patents, we may rely, in some circumstances, on trade secrets to protect our technology. We seek to protect our proprietary technology and processes, and
obtain and maintain ownership of certain technologies, in part, by confidentiality and invention assignment agreements with our employees, consultants,
scientific advisors, and contractors. We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security

other things, the research, development, testing, approval, manufacture, packaging, storage, recordkeeping, monitoring and reporting, labeling, advertising,
promotion, distribution, marketing, sales, import, and export of biotechnological and drug products such as those we are developing. In addition, labelers of
biotechnology and drug products (the entity owning the National Drug Code listed for a product) participating in Medicaid and Medicare are required to
comply with mandatory price reporting, discounts, rebates, and other requirements. The processes for obtaining regulatory approvals in the United States
and in other countries including Canada, along with compliance with applicable statutes and regulations, require the expenditure of substantial time and
financial resources.

FDA Regulation

In  the  United  States,  the  FDA  regulates  biologics  and  drug  products  under  the  Federal  Food,  Drug,  and  Cosmetic  Act  ("FDCA")  and  its  implementing
regulations. In addition to the FDCA and its implementing regulations, biological products are regulated under the Public Health Service Act ("PHSA") and
its  implementing  regulations.  The  process  required  by  the  FDA  before  product  candidates  may  be  marketed  in  the  United  States  generally  involves  the
following:

•

•

completion  of  preclinical  laboratory  tests,  animal  studies,  and  formulation  studies  in  compliance  with  the  FDA's  Good  Laboratory  Practice
("GLP")  regulations,  applicable  requirements  for  the  human  use  of  laboratory  animals,  such  as  the  Animal  Welfare  Act  ("AWA"),  or  other
applicable regulations;

submission to the FDA of an IND application, which must become effective before human clinical trials may begin at U.S. clinical trial sites;

25

Table of Contents

•

•

•

•

•

•

•

approval by an Institutional Review Board ("IRB") for each clinical site, or centrally, before a clinical trial may be initiated at that site;

adequate and well-controlled human clinical trials to establish the safety and efficacy, in the case of a drug product candidate, or safety, purity, and
potency, in the case of a biological product candidate for its intended use, performed in accordance with Good Clinical Practices ("GCPs") and
additional requirements for the protection of human research subjects and their health information;

development  of  manufacturing  processes  to  ensure  the  product  candidate's  identity,  strength,  quality,  purity,  and  potency  in  compliance  with
current GMP;

submission to the FDA of a New Drug Application ("NDA"), in the case of a drug product candidate, or a BLA, in the case of a biological product
candidate,  including  results  of  preclinical  testing,  detailed  information  about  the  CMC,  and  proposed  labeling  and  packaging  for  the  product
candidate;

satisfactory completion of an FDA advisory committee review, if applicable;

satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the products are produced to assess compliance
with  current  GMP,  and  to  assure  that  the  facilities,  methods,  and  controls  are  adequate  to  preserve  the  therapeutics'  identity,  strength,  quality,
purity, and potency as well as satisfactory completion of an FDA inspection of selected clinical sites, selected clinical investigators to determine
GCP compliance, and payment of user fees; and

FDA  review  and  approval  of  the  NDA,  or  licensure  of  a  BLA  to  permit  commercial  marketing  for  particular  indications  for  use,  including
agreement on post-marketing commitments, if applicable.

Preclinical Studies and IND Submission

The testing and approval process of product candidates requires substantial time, effort, and financial resources. Satisfaction of FDA pre-market approval
requirements typically takes many years and the actual time required may vary substantially based upon the type, complexity, and novelty of the product or
disease. Preclinical studies include laboratory evaluation of chemistry, pharmacology, toxicity, and product formulation, as well as animal studies to assess
potential  safety  and  efficacy.  Such  studies  must  generally  be  conducted  in  accordance  with  GLP,  the  AWA,  and  other  applicable  regulations  and
requirements. Prior to commencing the first clinical trial at a U.S. investigational site with a product candidate, an IND sponsor must submit the results of
the  preclinical  tests  and  preclinical  literature,  together  with  manufacturing  information,  analytical  data,  any  available  clinical  data  or  literature,  and
proposed clinical study protocols, among other things, to the FDA as part of an IND submission. Some preclinical studies may continue even after the IND
is in effect.

An  IND  application  automatically  becomes  effective  30  days  after  receipt  by  the  FDA,  unless  the  FDA,  within  the  30-day  time  period,  notifies  the
applicant  of  safety  concerns  or  questions  related  to  one  or  more  proposed  clinical  trials  and  places  the  trial  on  a  clinical  hold.  In  such  a  case,  the  IND
sponsor and the FDA must resolve any outstanding concerns before the clinical trial may begin. Even after the IND application has gone into effect and
clinical  testing  has  begun,  the  FDA  may  impose  clinical  holds  on  clinical  trials  due  to  safety  concerns  or  non-compliance  with  the  requirements  of
applicable regulations. If the FDA imposes a clinical hold, studies may not recommence without FDA authorization and then only under terms authorized
by the FDA. As a result, submission of an IND application may not result in FDA authorization to commence a clinical trial, and we cannot be sure that
once the clinical trials have begun, issues will not arise that will suspend or terminate such studies. A separate submission to an existing IND application
must also be made for each successive clinical trial conducted during product development.

Clinical Trials

Clinical trials involve the administration of the investigational product to human subjects (healthy volunteers or patients) under the supervision of qualified
investigators.  Clinical  trials  must  be  conducted  in  accordance  with  federal  regulations  and  GCP  requirements,  which  include  the  requirements  that  all
research subjects provide their informed consent in writing for their participation in any clinical trial, as well as the review and approval of the study by an
IRB.  Investigators  must  also  provide  certain  information  to  the  clinical  trial  sponsors  to  allow  the  sponsors  to  make  certain  financial  disclosures  to  the
FDA. Clinical trials are conducted under protocols detailing, among other things, the objectives of the trial, the trial procedures, the parameters to be used
in monitoring safety, the effectiveness criteria to be evaluated, and a statistical analysis plan. A protocol for each clinical trial, and any subsequent protocol
amendments, must be submitted to the FDA as part of the IND submission. If a product candidate is being investigated for multiple intended indications,
separate IND applications may also be required. In addition, an IRB at each study site participating in the clinical trial and/or a central IRB must review and
approve the plan for any clinical trial, informed consent forms, and communications to study subjects before a study commences at that site. An IRB

26

Table of Contents

is charged with protecting the welfare and rights of trial participants, and considers, among other things, whether the risks to individuals participating in the
trials are minimized and are reasonable in relation to anticipated benefits, and whether the planned human subject protections are adequate. The IRB must
continue to oversee the clinical trial while it is being conducted. Progress reports detailing the results of the clinical trials must also be submitted at least
annually to the FDA and the IRB and more frequently if SAEs or other significant safety information is found.

During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data, and clinical
trial  investigators.  Annual  progress  reports  detailing  the  results  of  the  clinical  trials  must  be  submitted  to  the  FDA.  Written  IND  safety  reports  must  be
promptly submitted to the FDA and the investigators for serious and unexpected adverse events, any findings from other studies, tests in laboratory animals
or in-vitro testing and other sources that suggest a significant risk for human subjects, or any clinically important increase in the rate of a serious suspected
adverse reaction over that listed in the protocol or investigator brochure. The sponsor must submit an IND safety report within 15 calendar days after the
sponsor determines that the information qualifies for reporting. The sponsor also must notify the FDA of any unexpected fatal or life-threatening suspected
adverse reaction within seven calendar days after the sponsor's initial receipt of the information. Phase 1, Phase 2, and Phase 3 clinical trials may not be
completed successfully within any specified period, if at all. The FDA may order the temporary, or permanent, discontinuation of a clinical trial at any time
or  impose  other  sanctions,  if  it  believes  that  the  clinical  trial  either  is  not  being  conducted  in  accordance  with  FDA  requirements  or  presents  an
unacceptable  risk  to  the  clinical  trial  patients.  If  the  FDA  issues  a  clinical  hold  halting  a  clinical  trial,  the  agency  must  notify  the  IND  sponsor  of  the
grounds for the hold. Any identified deficiencies must be resolved before the FDA will lift the hold and allow the clinical trial to begin or resume. There is
no guarantee the FDA will ever lift a clinical hold once put in place. An IRB may also require the clinical trial at the site to be halted, either temporarily or
permanently, for failure to comply with the IRB's requirements or if the trial poses an unexpected serious harm to subjects. The FDA or an IRB may also
impose conditions on the conduct of a clinical trial. Clinical trial sponsors may also choose to discontinue clinical trials as a result of risks to subjects, a
lack of favorable results, or changing business priorities.

Information about certain clinical trials, including a description of the study and study results, must be submitted within specific timeframes to the NIH for
public dissemination on its clinicaltrials.gov website. Sponsors or distributors of investigational products for the diagnosis, monitoring, or treatment of one
or more serious diseases or conditions must also have a publicly available policy on evaluating and responding to requests for expanded access requests.
This requirement applies on the earlier of the first initiation of a Phase 2 or Phase 3 trial of the investigational drug or, as applicable, 15 days after the drug
receives a designation as a breakthrough therapy, fast track product, or RMAT. Expanded access refers to the use of an investigational drug or biologic
when the primary purpose is to diagnose, monitor, or treat a patient’s disease or condition rather than to obtain the kind of information that is generally
derived from clinical trials. Expanded access may be appropriate when a patient has a serious or life-threatening disease, there is no comparable approved
therapy available, the patient cannot be enrolled in a clinical trial, the potential benefit outweighs the potential risks, and providing expanded access will
not  interfere  with  the  product  candidate’s  development  or  approval.  The  posting  of  an  expanded  access  policy  does  not  guarantee  access  to  the
investigational  drug  or  biologic.  When  a  sponsor  provides  expanded  access,  it  does  so  voluntarily.  The  FDA  cannot  compel  a  sponsor  to  provide  such
access.

The  manufacture  of  investigational  drugs  and  biologics  for  the  conduct  of  human  clinical  trials  is  subject  to  current  GMP  requirements.  Investigational
drugs,  biologics,  active  ingredients,  and  therapeutic  substances  imported  into  the  United  States  are  also  subject  to  regulation  by  the  FDA.  Further,  the
export  of  investigational  products  outside  of  the  United  States  is  subject  to  regulatory  requirements  of  the  receiving  country,  as  well  as  U.S.  export
requirements under the FDCA.

In  general,  for  purposes  of  NDA  and  BLA  approval,  human  clinical  trials  are  typically  conducted  in  three  sequential  phases,  which  may  overlap  or  be
combined.

•

•

•

Phase 1 — Studies are initially conducted in a small group of healthy human volunteers or subjects (e.g., 10 to 20 subjects) with the target disease
or  condition  to  test  the  product  candidate  for  safety,  dosage  tolerance,  structure-activity  relationships,  mechanism  of  action,  absorption,
metabolism, distribution, and excretion. If possible, Phase 1 trials may also be used to gain an initial indication of product effectiveness.

Phase 2 — Controlled studies are conducted in larger but still limited subject populations (e.g., a few hundred patients) with a specified disease or
condition to evaluate preliminary efficacy, identify optimal dosages, dosage tolerance and schedule, possible adverse effects and safety risks, and
expanded evidence of safety.

Phase 3 — These  adequate  and  well-controlled  clinical  trials  are  undertaken  in  expanded  subject  populations  (e.g.,  several  hundred  to  several
thousand patients), generally at geographically dispersed clinical trial sites, to generate enough data to provide statistically significant evidence of
clinical  efficacy  and  safety  of  the  product  candidate  for  approval,  to  establish  the  overall  risk-benefit  profile  of  the  product  candidate,  and  to
provide adequate information for

27

Table of Contents

the  labeling  of  the  product  candidate.  Typically,  two  Phase  3  trials  are  required  by  the  FDA  for  product  approval.  Under  some  limited
circumstances, however, the FDA may approve an NDA or BLA based upon a single Phase 3 clinical study.

The FDA may also require, or companies may conduct, additional clinical trials for the same indication after a product is approved. These are referred to as
Phase  4  studies  and  may  be  made  a  condition  to  be  satisfied  after  approval.  The  results  of  Phase  4  studies  can  confirm  or  refute  the  effectiveness  of  a
product candidate, and can provide important long-term safety information.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and
physical characteristics of the product candidate as well as finalize a process for manufacturing the product in commercial quantities in accordance with
current  GMP  requirements.  The  manufacturing  process  must  be  capable  of  consistently  producing  quality  batches  of  the  product  candidate  and,  among
other  things,  manufacturers  must  develop  methods  for  testing  the  identity,  strength,  quality,  potency,  and  purity  of  the  final  product.  Additionally,
appropriate  packaging  must  be  selected  and  tested,  and  stability  studies  must  be  conducted  to  demonstrate  that  the  product  candidate  does  not  undergo
unacceptable deterioration over its shelf life.

There  are  also  various  laws  and  regulations  regarding  laboratory  practices,  the  experimental  use  of  animals,  and  the  use  and  disposal  of  hazardous  or
potentially hazardous substances in connection with our research. In each of these areas, the FDA and other regulatory authorities have broad regulatory
and  enforcement  powers,  including  the  ability  to  levy  fines  and  civil  penalties,  suspend  or  delay  issuance  of  approvals,  seize  or  recall  products,  and
withdraw approvals.

Marketing Application Submission, Review by the FDA, and Marketing Approval

Assuming successful completion of the required clinical and preclinical testing, the results of product development, including CMC, non-clinical studies,
and  clinical  trial  results,  including  negative  or  ambiguous  results,  as  well  as  positive  findings,  are  all  submitted  to  the  FDA,  along  with  the  proposed
labeling, as part of an NDA, in the case of a drug, or BLA, in the case of a biologic, requesting approval to market the product for one or more indications.
In most cases, the submission of a marketing application is subject to a substantial application user fee. These user fees must be paid at the time of the first
submission of the application, even if the application is being submitted on a rolling basis. Fee waivers or reductions are available in certain circumstances.
One basis for a waiver of the application user fee is if the applicant employs fewer than 500 employees, including employees of affiliates, the applicant
does not have an approved marketing application for a product that has been introduced or delivered for introduction into interstate commerce, and the
applicant, including its affiliates, is submitting its first marketing application. Product candidates that are designated as orphan products, which are further
described below, are also not subject to application user fees unless the application includes an indication other than the orphan indication. The testing and
approval processes require substantial time and effort and there can be no assurance that the FDA will accept the BLA or NDA for filing and, even if filed,
that any approval will be granted on a timely basis, if at all.

In addition, under the Pediatric Research Equity Act ("PREA"), a BLA or NDA or supplement to a BLA or NDA for a new active ingredient, indication,
dosage form, dosage regimen, or route of administration, must contain data that is adequate to assess the safety and effectiveness of the product for the
claimed  indications  in  all  relevant  pediatric  subpopulations,  and  to  support  dosing  and  administration  for  each  pediatric  subpopulation  for  which  the
product is safe and effective. The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric
data until after the approval of the product for use in adults, or full or partial waivers from the pediatric data requirements. Orphan products are also exempt
from the PREA requirements.

The FDA also may require submission of a risk evaluation and mitigation strategy ("REMS") to ensure that the benefits of the product candidate outweigh
the risks. The REMS plan could include medication guides, physician communication plans, and elements to assure safe use, such as restricted distribution
methods,  patient  registries,  or  other  risk  minimization  tools.  An  assessment  of  the  REMS  must  also  be  conducted  at  set  intervals.  Following  product
approval, a REMS may also be required by the FDA if new safety information is discovered and the FDA determines that a REMS is necessary to ensure
that the benefits of the product continue to outweigh the risks. Any of these limitations on approval or marketing could restrict the commercial promotion,
distribution, prescription, or dispensing of products.

Once  the  FDA  receives  an  application,  it  generally  takes  60  days  to  review  the  NDA  or  BLA  to  determine  if  it  is  substantially  complete  to  permit  a
substantive review, before it accepts the application for filing. The FDA may refuse to review any application that it deems incomplete or not properly
reviewable  at  the  time  of  submission  and  may  request  additional  information.  In  this  event,  the  application  must  be  resubmitted  with  the  additional
information. The resubmitted application is

28

Table of Contents

also subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review.

Under the goals and policies agreed to by the FDA under the Prescription Drug User Fee Act ("PDUFA"), the FDA has set the review goal of completing
its review of 90% of all applications for new molecular entities within 10 months of the 60-day filing date. The FDA also has the review goal of completing
its review of 90% of non-new molecular entity marketing applications within 10 months of the agency's receipt of the application. These review goals are
referred to as the PDUFA date. The PDUFA date is only a goal, thus, the FDA does not always meet its PDUFA dates. The review process and the PDUFA
date  may  also  be  extended  if  the  FDA  requests  or  the  sponsor  otherwise  provides  substantial  additional  information  or  clarification  regarding  the
submission.

The FDA may also refer certain applications to an advisory committee. Before approving a product candidate for which no active ingredient (including any
ester or salt of an active ingredient) has previously been approved by the FDA, the FDA must either refer that product candidate to an external advisory
committee or provide in an action letter a summary of the reasons why the FDA did not refer the product candidate to an advisory committee. The FDA
may  also  refer  other  product  candidates  to  an  advisory  committee  if  the  FDA  believes  that  the  advisory  committee's  expertise  would  be  beneficial.  An
advisory committee is typically a panel that includes clinicians and other experts, which review, evaluate, and make a recommendation as to whether the
application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such
recommendations carefully when making decisions.

The  FDA  reviews  applications  to  determine,  among  other  things,  whether  a  product  candidate  meets  the  agency's  approval  standards  and  whether  the
manufacturing methods and controls are adequate to assure and preserve the product's identity, strength, quality, potency, and purity. Before approving a
marketing application, the FDA typically will inspect the facility or facilities where the product is manufactured, referred to as a Pre-Approval Inspection.
The  FDA  will  not  approve  an  application  unless  it  determines  that  the  manufacturing  processes  and  facilities,  including  contract  manufacturers  and
subcontractors,  are  in  compliance  with  current  GMP  requirements  and  are  adequate  to  assure  consistent  production  of  the  product  within  required
specifications.  Additionally,  before  approving  a  marketing  application,  the  FDA  will  inspect  one  or  more  clinical  trial  sites  to  assure  compliance  with
GCPs.  To  assure  current  GMP  and  GCP  compliance,  an  applicant  will  incur  significant  expenditure  of  time,  money,  and  effort  in  the  areas  of  training,
recordkeeping, production, and quality control.

After evaluating the marketing application and all related information, including the advisory committee recommendation, if any, and inspection reports
regarding the manufacturing facilities and clinical trial sites, the FDA may issue an approval letter, or, in some cases, a Complete Response Letter ("CRL").
A  CRL  indicates  that  the  review  cycle  for  the  application  is  complete  and  the  application  is  not  ready  for  approval.  It  also  describes  all  of  the  specific
deficiencies that the FDA identified. A CRL generally contains a statement of specific conditions that must be met in order to secure final approval of the
marketing  application,  and  may  require  additional  clinical  or  preclinical  testing  in  order  for  the  FDA  to  reconsider  the  application.  The  deficiencies
identified  may  be  minor,  for  example,  requiring  labeling  changes;  or  major,  for  example,  requiring  additional  clinical  trials.  If  a  CRL  is  issued,  the
applicant may either: resubmit the marketing application addressing all of the deficiencies identified in the letter; withdraw the application; or request an
opportunity  for  a  hearing.  The  FDA  has  the  goal  of  reviewing  90%  of  application  resubmissions  following  a  CRL  in  either  two  or  six  months  of  the
resubmission date, depending on the kind of resubmission. Even with the submission of this additional information, the FDA ultimately may decide that the
application does not satisfy the regulatory criteria for approval. If and when those conditions have been met to the FDA's satisfaction, the FDA may issue
an approval letter. An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications.

Even if the FDA approves a product, it may limit the approved indications or populations for use of the product, require that contraindications, warnings, or
precautions  be  included  in  the  product  labeling,  including  a  boxed  warning,  require  that  post-approval  studies,  including  Phase  4  clinical  trials,  be
conducted  to  further  assess  a  product's  safety  and  efficacy  after  approval,  require  testing  and  surveillance  programs  to  monitor  the  product  after
commercialization,  or  impose  other  conditions,  including  distribution  restrictions  or  other  risk  management  mechanisms  under  a  REMS,  which  can
materially affect the potential market and profitability of the product. The FDA may also not approve label statements that are necessary for successful
commercialization and marketing.

After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes, and additional labeling claims, are
subject to further testing requirements and FDA review and approval. The FDA may also withdraw the product approval if compliance with the pre- and
post-marketing  regulatory  standards  are  not  maintained  or  if  problems  occur  after  the  product  reaches  the  marketplace.  Further,  should  new  safety
information arise, additional testing, product labeling changes, or FDA notification may be required.

29

Table of Contents

For example, as a condition of approval of an NDA or BLA, the FDA may require post-marketing testing and surveillance to monitor the product's safety
or efficacy. In addition, holders of an approved NDA or BLA are required to submit annual reports and keep extensive records to report certain adverse
reactions and issues related to production to the FDA, to provide updated safety and efficacy information, and to comply with requirements concerning
advertising and promotional labeling for their products. Additionally, quality control and manufacturing procedures must continue to conform to current
GMP  regulations  and  practices,  as  well  as  the  manufacturing  conditions  of  approval  set  forth  in  the  NDA  or  BLA.  The  FDA  periodically  inspects
manufacturing  facilities  to  assess  compliance  with  current  GMP,  which  imposes  certain  procedural,  substantive,  and  recordkeeping  requirements.
Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain compliance with
current GMP and other aspects of regulatory compliance. If, after receiving approval, a company makes a material change in manufacturing equipment,
location, or process (all of which are, to some degree, incorporated in the NDA or BLA), additional regulatory review and approval may be required.

Future FDA inspections may identify current GMP compliance issues at manufacturing facilities or at the facilities of third-party suppliers that may disrupt
production or distribution or require substantial resources to correct and prevent recurrence of any deficiencies, and could result in fines or penalties by
regulatory authorities. In addition, discovery of problems with a product or the failure to comply with applicable requirements may result in restrictions on
a product, manufacturer, or holder of an approved NDA or BLA, including withdrawal or recall of the product from the market or other voluntary, FDA-
initiated or judicial action, including warning letters, fines, injunctions, civil penalties, license revocations, seizure, total or partial suspension of production
or criminal penalties, any of which could delay or prohibit further marketing. Newly discovered or developed safety or efficacy data may require changes
to a product's approved labeling, including the addition of new warnings and contraindications.

Emergency Use Authorization

The  FDA  has  the  authority  to  grant  an  EUA  to  allow  unapproved  medical  products,  including  vaccines,  to  be  used  in  a  public  health  emergency  to
diagnose, treat, or prevent serious or life-threatening diseases or conditions when there are no adequate, approved, and available alternatives. When issuing
an  EUA,  the  FDA  imposes  conditions  of  authorization,  with  which  the  sponsor  must  comply.  Such  conditions  include,  but  may  not  be  limited  to,
compliance with labeling, distribution of materials designed to ensure proper use, reporting obligations, and restrictions on advertising and promotion. The
EUA is only effective for the duration of the public health emergency. Although the criteria of an EUA differs from the criteria for approval of an NDA or
BLA,  EUAs  nevertheless  require  the  development  and  submission  of  data  to  satisfy  the  relevant  FDA  standards  and  a  number  of  ongoing  compliance
obligations.  In  addition,  the  FDA  expects  EUA  holders  to  work  toward  submission  of  an  NDA  or  BLA,  as  soon  as  possible.  The  FDA  may  revoke  or
terminate  the  EUA  sooner  if,  for  example,  the  holder  of  the  EUA  fails  to  comply  with  the  terms  of  the  EUA  or  the  product  is  determined  to  be  less
efficacious or safe than it was initially believed to be. The FDA may revoke an EUA if there is a failure to comply with the conditions of authorization.
There is no guarantee that a product candidate will meet the criteria for EUA.

Pediatric Exclusivity

Pediatric exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted, provides for the attachment of an additional
six months of marketing protection to the term of any existing regulatory exclusivity periods for both drugs and biologics, and also Orange Book listed
patents in the case of drugs. Conditions for exclusivity include the FDA's determination that information relating to the use of a new drug in the pediatric
population may produce health benefits in that population, the FDA making a written request for pediatric studies, and the applicant agreeing to perform
and report on the requested studies within the statutory timeframe.

Orphan Products

The Orphan Drug Act provides incentives for the development of products for rare diseases or conditions. Specifically, sponsors may apply for and receive
ODD  if  a  product  candidate  is  intended  to  treat  rare  diseases  or  conditions,  which  generally  are  diseases  or  conditions  affecting  less  than  0.2  million
individuals in the United States, or affecting more than 0.2 million individuals in the United States and for which there is no reasonable expectation that the
cost of developing and making the product available in the United States will be recovered from U.S. sales. ODD must be requested before submitting an
NDA or BLA. Additionally, sponsors must present a plausible hypothesis for clinical superiority to obtain ODD if there is a product already approved by
the  FDA  that  is  considered  by  the  FDA  to  be  the  same  and  is  intended  for  the  same  indication.  This  hypothesis  must  be  demonstrated  to  obtain  ODD
exclusivity. If granted, prior to product approval, ODD entitles a party to financial incentives such as opportunities for grant funding towards clinical study
costs, tax advantages, and certain user-fee waivers. The tax advantages, however, were limited in the 2017 Tax Cuts and Jobs Act. After the FDA grants
ODD, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. ODD does not convey any advantage in, or

30

Table of Contents

shorten the duration of, the regulatory review and approval process. The first NDA or BLA applicant to receive FDA approval for a particular active moiety
to  treat  a  particular  disease  with  ODD  generally  is  entitled  to  a  seven-year  exclusive  marketing  period  in  the  United  States  for  that  product,  for  that
indication. During the seven-year exclusivity period, the FDA may not approve any other applications to market the same drug for the same disease, except
in limited circumstances, such as a showing of clinical superiority to the product with ODD exclusivity by means of greater effectiveness, greater safety, or
providing  a  major  contribution  to  patient  care.  ODD  exclusivity  does  not  prevent  the  FDA  from  approving  a  different  drug  for  the  same  disease  or
condition, or the same drug for a different disease or condition.

Patent Term Restoration

If  approved,  drug  and  biologic  products  may  also  be  eligible  for  periods  of  U.S.  patent  term  restoration.  If  granted,  patent  term  restoration  extends  the
patent life of a single unexpired patent, that has not previously been extended, for a maximum of five years. The total patent life of the product with the
extension also cannot exceed 14 years from the product's approval date. Subject to prior limitations, the period of extension is calculated by adding half of
the time from the effective date of an IND application to the initial submission of a marketing application, and all of the time between the submission of the
marketing application and its approval. This period may also be reduced by any time that the applicant did not act with due diligence. Only one patent
claiming each approved product is eligible for restoration and the patent holder must apply for restoration within 60 days of approval. The U.S. Patent and
Trademark Office ("USPTO"), in consultation with the FDA, reviews and approves the application for patent term restoration.

Special FDA Expedited Review and Approval Programs

The FDA has various programs that are intended to expedite or simplify the process for the development and FDA review of certain product candidates that
are intended for the treatment of serious or life-threatening diseases or conditions, and demonstrate the potential to address unmet medical needs or present
a  significant  improvement  over  existing  therapy.  The  purpose  of  these  programs  is  to  provide  important  new  therapeutics  to  patients  earlier  than  under
standard FDA review procedures. These expedited programs include fast track designation, breakthrough therapy designation, priority review, accelerated
approval,  and  RMAT  designation.  Each  of  these  programs  has  its  own  features  and  qualifying  criteria.  A  sponsor  must  submit  a  request  for  fast  track
designation, breakthrough therapy designation, or priority review, which may or may not be granted by the FDA.

To be eligible for a fast track designation, the FDA must determine, based on the request of a sponsor, that a product candidate is intended to treat a serious
or life threatening disease or condition and demonstrates the potential to address an unmet medical need. If fast track designation is obtained, sponsors may
be  eligible  for  more  frequent  development  meetings  and  correspondence  with  the  FDA.  In  addition,  the  FDA  may  initiate  review  of  sections  of  an
application  before  the  application  is  complete.  This  "rolling  review"  is  available  if  the  applicant  provides  and  the  FDA  approves  a  schedule  for  the
remaining information. Whether the FDA is able to commence its review of portions of an application before receipt of the complete submission depends
on a number of factors. In some cases, a fast track product may be eligible for accelerated approval or priority review.

The  FDA  may  give  a  priority  review  designation  to  product  candidates  that  are  intended  to  treat  serious  conditions  and,  if  approved,  would  provide
significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of the serious condition. A priority review means that the
goal for the FDA is to review an application within six months, rather than the standard review of 10 months under current PDUFA guidelines.

Drug or biological products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic
benefit over existing treatments may receive accelerated approval, which means the FDA may approve the product based upon a surrogate endpoint that is
reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably
likely  to  predict  an  effect  on  irreversible  morbidity  or  mortality  or  other  clinical  benefit,  taking  into  account  the  severity,  rarity,  or  prevalence  of  the
condition and the availability or lack of alternative treatments. A drug or biologic candidate approved on this basis is subject to rigorous post-marketing
compliance  requirements,  including  the  completion  of  Phase  4  or  post-approval  clinical  trials  to  confirm  the  effect  of  the  product.  Failure  to  conduct
required post-approval studies, or confirm a clinical benefit during post-marketing studies, will allow the FDA to withdraw the drug or biologic from the
market on an expedited basis. All promotional materials for drug or biologic candidates approved under accelerated regulations are subject to prior review
by the FDA.

Under the provisions of the Food and Drug Administration Safety and Innovation Act, enacted in 2012, a sponsor can request designation of a product
candidate as a "breakthrough therapy." A breakthrough therapy is defined as a product that is intended, alone or in combination with one or more other
products, to treat a serious or life-threatening disease or condition, and

31

Table of Contents

preliminary  clinical  evidence  indicates  that  the  product  may  demonstrate  substantial  improvement  over  existing  therapies  on  one  or  more  clinically
significant  endpoints,  such  as  substantial  treatment  effects  observed  early  in  clinical  development.  Products  designated  as  breakthrough  therapies  are
eligible for intensive guidance on an efficient development program beginning as early as Phase 1 trials, a commitment from the FDA to involve senior
managers and experienced review staff in a proactive collaborative and cross-disciplinary review, rolling review, and the facilitation of cross-disciplinary
review.

Established under the 21st Century Cures Act, RMAT designation is a dedicated program designed to expedite the drug development and review processes
for promising pipeline products, including genetic therapies. A regenerative medicine advanced therapy is eligible for RMAT designation if it is intended to
treat, modify, reverse, or cure a serious or life threatening disease or condition, and preliminary clinical evidence indicates that the drug or therapy has the
potential  to  address  unmet  medical  needs  for  such  disease  or  condition.  Similar  to  breakthrough  therapy  designation,  RMAT  designation  provides  the
benefits of intensive FDA guidance on efficient drug development, including the ability for early interactions with FDA to discuss surrogate or intermediate
endpoints,  potential  ways  to  support  accelerated  approval  and  satisfy  post-approval  requirements,  potential  priority  review  of  a  BLA,  and  other
opportunities to expedite development and review.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or
decide that the time period for FDA review or approval will not be shortened.

Post-approval Requirements

Any products manufactured or distributed pursuant to FDA approvals are subject to extensive and continuing regulation by the FDA, including, among
other  things,  requirements  related  to  manufacturing,  recordkeeping,  and  reporting,  including  adverse  experience  reporting,  deviation  reporting,  shortage
reporting, and periodic reporting, product sampling and distribution, advertising, marketing, promotion, certain electronic records and signatures, and post-
approval obligations imposed as a condition of approval, such as Phase 4 clinical trials, REMS, and surveillance to assess safety and effectiveness after
commercialization.

After approval, most changes to the approved product, such as adding new indications or other labeling claims are subject to FDA review and approval.
There also are continuing annual program user fee requirements for approved products, excluding orphan products. In addition, manufacturers and other
entities involved in the manufacture and distribution of approved therapeutics are required to register their establishments with the FDA and certain state
agencies, list their products, and are subject to periodic announced and unannounced inspections by the FDA and these state agencies for compliance with
current  GMP  and  other  requirements.  Manufacturers  must  continue  to  expend  time,  money,  and  effort  in  the  areas  of  production  and  quality-control  to
maintain compliance with current GMP. Regulatory authorities may undertake regulatory enforcement action, withdraw product approvals, require label
modifications, or request product recalls, among other actions, if a company fails to comply with regulatory standards, if it encounters problems following
initial marketing, or if previously unrecognized problems are subsequently discovered.

Changes to the manufacturing process are strictly regulated and often require FDA approval or notification before being implemented. FDA regulations
also require investigation and correction of any deviations from current GMP and specifications, and impose reporting and documentation requirements
upon the sponsor and any third-party manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money,
and effort in the area of production and quality control to maintain current GMP compliance.

The FDA also strictly regulates marketing, labeling, advertising, and promotion of products that are placed on the market. Physicians, in their independent
professional medical judgment, may prescribe legally available products for unapproved indications that are not described in the product's labeling and that
differ from those tested and approved by the FDA. Biotechnological companies, however, are required to promote their products only for the approved
indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting
the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability, including,
but not limited to, criminal and civil penalties under the FDCA and False Claims Act ("FCA"), exclusion from participation in federal healthcare programs,
mandatory compliance programs under corporate integrity agreements, suspension and debarment from government contracts, and refusal of orders under
existing government contracts. In addition, newly discovered or developed safety or efficacy data may require changes to a product's approved labeling,
including the addition of new warnings and contraindications.

In  addition,  the  distribution  of  prescription  biotechnological  samples  is  subject  to  the  Prescription  Drug  Marketing  Act  ("PDMA"),  which  regulates  the
distribution  of  samples  at  the  federal  level.  Both  the  PDMA  and  state  laws  limit  the  distribution  of  prescription  biotechnological  product  samples  and
impose requirements to ensure accountability in distribution. Free trial or

32

Table of Contents

starter  prescriptions  provided  through  pharmacies  are  also  subject  to  regulations  under  the  Medicaid  Drug  Rebate  Program  ("MDRP")  and  potential
liability under anti-kickback and false claims laws.

Moreover, the Drug Quality and Security Act imposes obligations on sponsors of biotechnological products related to product tracking and tracing. Among
the requirements of this legislation, sponsors are required to provide certain information regarding the products to individuals and entities to which product
ownership is transferred, are required to label products with a product identifier, and are required to keep certain records regarding the product. The transfer
of  information  to  subsequent  product  owners  by  sponsors  is  also  required  to  be  done  electronically.  Sponsors  must  also  verify  that  purchasers  of  the
sponsors'  products  are  appropriately  licensed.  Further,  under  this  legislation,  manufactures  have  product  investigation,  quarantine,  disposition,  and
notification  responsibilities  related  to  counterfeit,  diverted,  stolen,  and  intentionally  adulterated  products  that  would  result  in  serious  adverse  health
consequences or death to humans, as well as products that are the subject of fraudulent transactions or which are otherwise unfit for distribution such that
they would be reasonably likely to result in serious health consequences or death. Similar requirements additionally are and will be imposed through this
legislation on other companies within the biotechnological product supply chain, such as distributors and dispensers, as well as certain sponsor licensees
and affiliates.

Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing
processes,  or  failure  to  comply  with  regulatory  requirements,  may  result  in  significant  regulatory  actions.  Such  actions  may  include  refusal  to  approve
pending applications, license or approval suspension or revocation, imposition of a clinical hold or termination of clinical trials, warning letters, untitled
letters,  Form  483s,  cyber  letters,  modification  of  promotional  materials  or  labeling,  provision  of  corrective  information,  imposition  of  post-market
requirements including the need for additional testing, imposition of distribution or other restrictions under a REMS, product recalls, product seizures or
detentions, refusal to allow imports or exports, total or partial suspension of production or distribution, FDA debarment, injunctions, fines, consent decrees,
corporate  integrity  agreements,  suspension  and  debarment  from  government  contracts,  refusal  of  orders  under  existing  government  contracts,  exclusion
from  participation  in  federal  and  state  healthcare  programs,  restitution,  disgorgement,  civil  or  criminal  penalties  including  fines  and  imprisonment,  and
adverse publicity, among other adverse consequences.

Additional controls for biologics

To help reduce the increased risk of the introduction of adventitious agents, the PHSA emphasizes the importance of manufacturing controls for products
whose  attributes  cannot  be  precisely  defined.  The  PHSA  also  provides  authority  to  the  FDA  to  immediately  suspend  licenses  in  situations  where  there
exists a danger to public health, to prepare or procure products in the event of shortages and critical public health needs, and to authorize the creation and
enforcement of regulations to prevent the introduction or spread of communicable diseases in the United States and between states.

After  a  BLA  is  approved,  the  product  may  also  be  subject  to  official  lot  release  as  a  condition  of  approval.  As  part  of  the  manufacturing  process,  the
manufacturer is required to perform certain tests on each lot of the product before it is released for distribution. If the product is subject to official release
by the FDA, the manufacturer submits samples of each lot of the product to the FDA together with a release protocol showing the results of all of the
manufacturer's  tests  performed  on  the  lot.  The  FDA  may  also  perform  certain  confirmatory  tests  on  lots  of  some  products  before  releasing  the  lots  for
distribution by the manufacturer. In addition, the FDA conducts laboratory research related to the regulatory standards on the safety, purity, potency, and
effectiveness of biological products.

Gene therapy products are also subject to the NIH Guidelines for Research Involving Recombinant or Synthetic Nucleic Acid Molecules, which require,
among other things, that trials involving recombinant or synthetic nucleic acid molecules be reviewed by an Institutional Biosafety Committee ("IBC").
The IBC reviews, approves, and supervises research involving recombinant or synthetic nucleic acid molecules.

In addition to the regulations discussed above, there are a number of additional standards that apply to clinical trials involving the use of gene therapy. The
FDA  has  issued  various  guidance  documents  regarding  gene  therapies,  which  outline  additional  factors  that  the  FDA  will  consider  during  product
development that relate to, among other things: the proper preclinical assessment of gene therapies; the CMC information that should be included in an
IND application; the proper design of tests to measure product potency in support of an IND or BLA application; and measures to observe delayed adverse
effects  in  subjects  who  have  been  exposed  to  investigational  gene  therapies  when  the  risk  of  such  effects  is  high.  Further,  the  FDA  recommends  that
sponsors observe subjects for potential gene therapy-related delayed adverse events for a prolonged period of time.

Fraud and Abuse, Data Privacy and Security, and Transparency Laws and Regulations

Our business activities, including but not limited to, research, marketing, sales, promotion, distribution, medical education, and other activities following
product approval will be subject to regulation by numerous federal and state regulatory and law enforcement authorities in the United States in addition to
the FDA, including potentially the Department of Justice, the Department of Health and Human Services and its various divisions, including the Centers for
Medicare and Medicaid Services ("CMS") and the Health Resources and Services Administration, the Department of Veterans Affairs, the Department of
Defense, and state and local governments. Our business activities must comply with numerous healthcare laws, including but not limited to, anti-kickback
and false claims laws and regulations as well as data privacy and security laws and regulations, which are described below, as well as state and federal
consumer protection and unfair competition laws. Moreover, to the extent that we license the right to sell our product candidates, if approved, to another
entity  under  that  entity's  labeler  code,  the  licensee  would  have  regulatory  responsibilities,  including  healthcare,  reimbursement,  pricing,  and  reporting
regulatory responsibilities.

The federal Anti-Kickback Statute, which regulates, among other things, marketing practices, educational programs, pricing policies, and relationships with
healthcare  providers  or  other  entities,  prohibits,  among  other  things,  any  person  or  entity,  from  knowingly  and  willfully  offering,  paying,  soliciting,  or
receiving  any  remuneration,  directly  or  indirectly,  overtly  or  covertly,  in  cash  or  in  kind,  to  induce  or  in  return  for  purchasing,  leasing,  ordering,  or
arranging for or recommending the purchase, lease, or order, or the referral to another for the furnishing or arranging of any item or service reimbursable
under  Medicare,  Medicaid,  or  other  federal  healthcare  programs,  in  whole  or  in  part.  The  term  "remuneration"  has  been  interpreted  broadly  to  include
anything of value. The Anti-Kickback Statute has been interpreted to apply to arrangements between biotechnological industry members on one hand and
prescribers, purchasers, formulary managers, and beneficiaries on the other. There are certain statutory exceptions and regulatory safe harbors protecting
some  common  activities  from  prosecution.  The  exceptions  and  safe  harbors  are  drawn  narrowly,  and  practices  that  involve  remuneration  that  may  be
alleged  to  be  intended  to  induce  prescribing,  purchases,  or  recommendations  may  be  subject  to  scrutiny  if  they  do  not  qualify  for  an  exception  or  safe
harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se
illegal under the Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of
all  of  its  facts  and  circumstances.  Several  courts  have  interpreted  the  statute's  intent  requirement  to  mean  that  if  any  one  purpose  of  an  arrangement
involving remuneration is to induce referrals of a federal healthcare covered business, including purchases of products paid by federal healthcare programs,
the statute has been violated. The Patient Protection and Affordable Care Act of 2010, as amended (the "ACA"), modified the intent requirement under the
Anti-Kickback Statute to a stricter standard, such that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate
it  in  order  to  have  committed  a  violation.  In  addition,  the  ACA  also  provided  that  a  violation  of  the  federal  Anti-Kickback  Statute  is  grounds  for  the
government or a whistleblower to assert that a claim for payment of items or services resulting from such violation constitutes a false or fraudulent claim
for purposes of the federal civil FCA.

The federal civil FCA prohibits, among other things, any person or entity from knowingly presenting, or causing to be presented, a false or fraudulent claim
for payment to, or approval by, the federal government, knowingly making, using, or causing to be made or used a false record or statement material to a
false or fraudulent claim to the federal government, or avoiding, decreasing, or concealing an obligation to pay money to the federal government. A claim
includes "any request or demand" for money or property presented to the U.S. government. The civil FCA has been used to assert liability on the basis of
kickbacks  and  other  improper  referrals,  improperly  reported  government  pricing  metrics  such  as  Best  Price  or  Average  Manufacturer  Price  ("AMP"),
improper use of Medicare provider or supplier numbers when detailing a provider of services, improper promotion of off-label uses not expressly approved
by the FDA in a product's label, and allegations as to misrepresentations with respect to products, contract requirements, and services rendered. In addition,
private payors have been filing follow-on lawsuits alleging fraudulent misrepresentation, although establishing liability and damages in these cases is more
difficult  than  under  the  FCA.  Intent  to  deceive  is  not  required  to  establish  liability  under  the  civil  FCA.  Civil  FCA  actions  may  be  brought  by  the
government or may be brought by private individuals on behalf of the government, called "qui tam" actions. If the government decides to intervene in a qui
tam action and prevails in the lawsuit, the individual will share in the proceeds from any fines or settlement funds. If the government declines to intervene,
the  individual  may  pursue  the  case  alone.  The  civil  FCA  provides  for  treble  damages  and  a  civil  penalty  for  each  false  claim,  such  as  an  invoice  or
pharmacy  claim  for  reimbursement,  which  can  aggregate  into  millions  of  dollars.  For  these  reasons,  since  2004,  FCA  lawsuits  against  biotechnological
companies  have  increased  significantly  in  volume  and  breadth,  leading  to  several  substantial  civil  and  criminal  settlements,  as  much  as  $3.0  billion,
regarding certain sales practices and promoting off label uses. Civil FCA liability may further be imposed for known Medicare or Medicaid overpayments,
for  example,  overpayments  caused  by  understated  rebate  amounts,  that  are  not  refunded  within  60  days  of  discovering  the  overpayment,  even  if  the
overpayment  was  not  caused  by  a  false  or  fraudulent  act.  In  addition,  conviction  or  civil  judgment  for  violating  the  FCA  may  result  in  exclusion  from
federal health care programs, suspension and debarment from government contracts, and refusal of orders under existing government contracts.

34

Table of Contents

The government may further prosecute conduct constituting a false claim under the criminal FCA. The criminal FCA prohibits the making or presenting of
a claim to the government knowing such claim to be false, fictitious, or fraudulent and, unlike the civil FCA, requires proof of intent to submit a false
claim.

The  civil  monetary  penalties  statute  is  another  potential  statute  under  which  biotechnological  companies  may  be  subject  to  enforcement.  Among  other
things, the civil monetary penalties statue imposes fines against any person who is determined to have knowingly presented, or caused to be presented,
claims to a federal healthcare program that the person knows, or should know, is for an item or service that was not provided as claimed or is false or
fraudulent.

Payment or reimbursement of prescription therapeutics by Medicaid or Medicare requires the product's labeler to submit certified pricing information to
CMS. The Medicaid Drug Rebate statute requires labelers, as a condition of payment by Medicaid, to calculate and report price points, which are used to
determine  Medicaid  rebate  payments  shared  between  the  states  and  the  federal  government  and  Medicaid  payment  rates  for  certain  therapeutics,  to  pay
quarterly  rebates  on  prescriptions  paid  by  Medicaid,  and  to  provide  a  discount  based  on  the  Medicaid  rebate  percentage  to  certain  hospitals  and  clinics
under the 340B program. For most therapeutics paid under Medicare Part B, labelers must also calculate and report their Average Sales Price, which is used
to  determine  the  Medicare  Part  B  payment  rate.  In  addition,  therapeutics  covered  by  Medicaid  are  subject  to  an  additional  inflation  penalty  which  can
substantially increase rebate payments. For products approved under a BLA (including biosimilars) or an NDA, the Veterans Health Care Act ("VHCA")
requires labelers, as a condition of payment by Medicaid, to calculate and report to the Veterans Administration ("VA") a different price called the Non-
Federal  AMP,  which  is  used  to  determine  the  maximum  price  that  can  be  charged  to  certain  federal  agencies,  referred  to  as  the  Federal  Ceiling  Price
("FCP").  Like  the  Medicaid  rebate  amount,  the  FCP  includes  an  inflation  penalty.  A  Department  of  Defense  statute  and  regulation  requires  labelers  to
provide this discount on therapeutics dispensed by retail pharmacies when paid by the TRICARE Program, the health care program for military personnel,
retirees,  and  related  beneficiaries.  All  of  these  price  reporting  requirements  create  risk  of  submitting  false  information  to  the  government,  and  potential
FCA liability.

The VHCA also requires labelers of covered therapeutics participating in the Medicaid program to enter into Federal Supply Schedule contracts with the
VA  through  which  their  covered  therapeutics  must  be  sold  to  certain  federal  agencies  at  FCP.  This  necessitates  compliance  with  applicable  federal
procurement laws and regulations, including submission of commercial sales and pricing information, and subjects us to contractual remedies as well as
administrative,  civil,  and  criminal  sanctions.  In  addition,  the  VHCA  requires  labelers  participating  in  Medicaid  to  agree  to  provide  different  mandatory
discounts  to  certain  Public  Health  Service  grantees  and  other  safety  net  hospitals  and  clinics  under  the  340B  program  based  on  the  labelers'  reported
Medicaid  pricing  information.  The  340B  program  has  its  own  regulatory  authority  to  impose  sanctions  for  non-compliance  and  adjudicate  overcharge
claims against labelers by the purchasing entities.

The  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996  ("HIPAA")  also  created  federal  criminal  statutes  that  prohibit,  among  other
actions,  knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  or  to  obtain,  by  means  of  false  or  fraudulent  pretenses,
representations or promises, any of the money or property owned by, or under the custody or control of, a healthcare benefit program, regardless of whether
the payor is public or private, in connection with the delivery or payment for health care benefits, knowingly and willfully embezzling or stealing from a
health care benefit program, willfully obstructing a criminal investigation of a health care offense and knowingly and willfully falsifying, concealing, or
covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare
benefits, items, or services relating to healthcare matters. Additionally, the ACA amended the intent requirement of certain of these criminal statutes under
HIPAA so that a person or entity no longer needs to have actual knowledge of the statute, or the specific intent to violate it, to have committed a violation.

The ACA further created new federal requirements for reporting, by applicable drug manufacturers of covered therapeutics, payments and other transfers of
value to physicians and teaching hospitals, and ownership and investment interests held by physicians and other healthcare providers and their immediate
family members, including the Physician Payments Sunshine Act.

Further, we may 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 for Economic and Clinical Health Act ("HITECH") and its respective implementing regulations imposes
certain requirements on covered entities relating to the privacy, security, and transmission of certain individually identifiable health information, known as
protected health information. Among other things, HITECH, through its implementing regulations, makes HIPAA's security standards and certain privacy
standards directly applicable to business associates, defined as a person or organization, other than a member of a covered entity's workforce, that creates,
receives, maintains, or transmits protected health information on behalf of a covered entity for a function or activity regulated by HIPAA. HITECH also
strengthened  the  civil  and  criminal  penalties  that  may  be  imposed  against  covered  entities,  business  associates,  and  individuals,  and  gave  state  attorney
generals new authority to file

35

Table of Contents

civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys' fees and costs associated with pursuing
federal civil actions. In addition, other federal and state laws may govern the privacy and security of health and other information in certain circumstances,
many of which differ from each other in significant ways and may not be preempted by HIPAA, thus complicating compliance efforts.

Many states have also adopted laws similar to each of the above federal laws, which may be broader in scope and apply to items or services reimbursed by
any  third-party  payor,  including  commercial  insurers.  Certain  state  laws  also  regulate  sponsors'  use  of  prescriber-identifiable  data.  Certain  states  also
require implementation of commercial compliance programs and compliance with the pharmaceutical industry's voluntary compliance guidelines and the
applicable compliance guidance promulgated by the federal government, or otherwise restrict payments or the provision of other items of value that may be
made to healthcare providers and other potential referral sources; impose restrictions on marketing practices; or require drug companies to track and report
information related to payments, gifts, and other items of value to physicians and other healthcare providers.

Recently, states have enacted or are considering legislation intended to make drug prices more transparent and deter significant price increases, typically as
consumer protection laws. These laws may affect our future sales, marketing, and other promotional activities by imposing administrative and compliance
burdens.

If our operations are found to be in violation of any of the laws or regulations described above or any other applicable laws, we may be subject to penalties
or  other  enforcement  actions,  including  criminal  and  significant  civil  monetary  penalties,  damages,  fines,  disgorgement,  imprisonment,  exclusion  from
participation  in  government  healthcare  programs,  corporate  integrity  agreements,  suspension  and  debarment  from  government  contracts,  and  refusal  of
orders  under  existing  government  contracts,  reputational  harm,  diminished  profits  and  future  earnings,  and  the  curtailment  or  restructuring  of  our
operations, any of which could adversely affect our ability to operate our business and our results of operations. Enforcement actions can be brought by
federal  or  state  governments,  or  as  "qui  tam"  actions  brought  by  individual  whistleblowers  in  the  name  of  the  government  under  the  civil  FCA  if  the
violations are alleged to have caused the government to pay a false or fraudulent claim.

To the extent that any of our products are sold in a foreign country, we may be subject to similar foreign laws and regulations, which may include, for
instance,  applicable  post-marketing  requirements,  including  safety  surveillance,  anti-fraud  and  abuse  laws,  and  implementation  of  corporate  compliance
programs and reporting of payments or transfers of value to healthcare professionals.

Coverage and Reimbursement

The commercial success of our product candidates and our ability to commercialize any approved product candidates successfully will depend in part on
the extent to which governmental payor programs at the federal and state levels, including Medicare and Medicaid, private health insurers, and other third-
party payors provide coverage for and establish adequate reimbursement levels for our product candidates. Government authorities, private health insurers,
and other organizations generally decide which therapeutics they will pay for and establish reimbursement levels for healthcare. Medicare is a federally
funded program managed by CMS through local fiscal intermediaries and carriers that administer coverage and reimbursement for certain healthcare items
and services furnished to the elderly and disabled. Medicaid is an insurance program for certain categories of patients whose income and assets fall below
state  defined  levels  and  who  are  otherwise  uninsured  that  is  both  federally  and  state  funded  and  managed  by  each  state.  The  federal  government  sets
general guidelines for Medicaid and each state creates specific regulations that govern its individual program, including supplemental rebate programs that
restrict  coverage  to  therapeutics  on  the  state  Preferred  Drug  List.  Similarly,  government  laws  and  regulations  establish  the  parameters  for  coverage  of
prescription therapeutics by health plans participating in state exchanges and TRICARE. Some states have also created pharmacy assistance programs for
individuals who do not qualify for federal programs. In the United States, private health insurers and other third-party payors often provide reimbursement
for  products  and  services  based  on  the  level  at  which  the  government  provides  reimbursement  through  the  Medicare  or  Medicaid  programs  for  such
products and services.

In  the  United  States,  the  EU,  and  other  potentially  significant  markets  for  our  product  candidates,  government  authorities  and  third-party  payors  are
increasingly attempting to limit or regulate the price of medical products and services, particularly for new and innovative products and therapies, which
often has resulted in average selling prices lower than they would otherwise be and sometimes at or below the provider's acquisition cost. In the United
States, it is also common for government and private health plans to use coverage determinations to leverage rebates from labelers in order to reduce the
plans' net costs. These restrictions and limitations influence the purchase of healthcare services and products and lower the realization on labelers' sales of
prescription  therapeutics.  Third-party  payors  are  developing  increasingly  sophisticated  methods  of  controlling  healthcare  costs.  Third-party  payors  may
limit coverage to specific therapeutic products on an approved list, or formulary, which might not include all of the FDA approved products for a particular
indication or might impose high copayment amounts to influence patient choice. Third-party payors also control costs by requiring prior authorization or
imposing other dispensing

36

Table of Contents

restrictions before covering certain products and by broadening therapeutic classes to increase competition. Third-party payors are increasingly challenging
the  price  and  examining  the  medical  necessity  and  cost-effectiveness  of  medical  products  and  services,  in  addition  to  their  safety  and  efficacy.  Absent
clinical  differentiators,  third-party  payors  may  treat  products  as  therapeutically  equivalent  and  base  formulary  decisions  on  net  cost.  To  lower  the
prescription cost, labelers frequently rebate a portion of the prescription price to the third-party payors. Recently, purchasers and third-party payors have
begun to focus on value of new therapeutics and sought agreements in which price is based on achievement of performance metrics.

Federal programs also impose price controls through mandatory ceiling prices on purchases by federal agencies and federally funded hospitals and clinics
and  mandatory  rebates  on  retail  pharmacy  prescriptions  paid  by  Medicaid  and  TRICARE.  These  restrictions  and  limitations  influence  the  purchase  of
healthcare services and products. Legislative proposals to reform healthcare or reduce costs under government programs may result in lower reimbursement
for  our  product  candidates  or  exclusion  of  our  product  candidates  from  coverage.  In  addition,  government  programs  like  Medicaid  include  substantial
penalties for increasing commercial prices over the rate of inflation which can affect realization and return on investment.

Private payors often rely on the lead of the governmental payors in rendering coverage and reimbursement determinations. Therefore, achieving favorable
CMS  coverage  and  reimbursement  is  usually  a  significant  gating  issue  for  successful  introduction  of  a  new  product.  In  addition,  many  government
programs as a condition of participation mandate fixed discounts or rebates from labelers regardless of formulary position or utilization, and then rely on
competition in the market to attain further price reductions, which can greatly reduce realization on the sale.

Further, the increased emphasis on managed healthcare in the United States and on country and regional pricing and reimbursement controls in the EU will
put additional pressure on product pricing, reimbursement, and utilization, which may adversely affect our future product sales and results of operations.
These pressures can arise from rules and practices of managed care groups, competition within therapeutic classes, judicial decisions and governmental
laws and regulations related to Medicare, Medicaid, and healthcare reform, biotechnological coverage and reimbursement policies, and pricing in general.
Patients  who  are  prescribed  treatments  for  their  conditions  and  providers  performing  the  prescribed  services  generally  rely  on  third-party  payors  to
reimburse  all  or  part  of  the  associated  healthcare  costs.  Sales  of  our  product  candidates  will  therefore  depend  substantially,  both  domestically  and
internationally,  on  the  extent  to  which  the  costs  of  our  product  candidates,  if  approved,  will  be  paid  by  health  maintenance,  managed  care,  pharmacy
benefit, and similar healthcare management organizations, or reimbursed by government health administration authorities, such as Medicare and Medicaid,
private health insurers, and other third-party payors.

As  a  result  of  the  above,  we  may  need  to  conduct  expensive  pharmacoeconomic  studies  in  order  to  demonstrate  the  medical  necessity  and  cost-
effectiveness  of  our  product  candidates,  if  approved,  in  addition  to  the  costs  required  to  obtain  FDA  approvals.  Our  product  candidates  may  not  be
considered  medically  necessary  or  cost-effective,  or  the  rebate  percentages  required  to  secure  coverage  may  not  yield  an  adequate  margin  over  cost.
Additionally, companies are increasingly finding it necessary to establish bridge programs to assist patients with access to new therapies during protracted
initial coverage determination periods.

Moreover, a payor's decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved or that significant
price concessions will not be required to avoid restrictive conditions. High health plan copayment requirements may result in patients refusing prescriptions
or seeking alternative therapies. Additionally, where a new indication has been approved for a drug or biologic previously approved under a different NDA
or BLA, health plans may cover off-label use of the original drug, even if it cannot be marketed for the new indication. Adequate third-party reimbursement
may  not  be  available  to  enable  us  to  maintain  price  levels  sufficient  to  realize  an  appropriate  return  on  our  investment  in  therapeutic  development.
Legislative  action  to  reform  healthcare  or  reduce  costs  under  government  insurance  programs  may  result  in  lower  reimbursement  for  our  products  and
product candidates or exclusion of our products and product candidates from coverage. The cost containment measures that healthcare payors and providers
are instituting and any healthcare reform could significantly reduce our revenues from the sale of any approved product candidates. We cannot provide any
assurances that we will be able to obtain and maintain third-party coverage or adequate reimbursement for our product candidates in whole or in part.

Healthcare Reform Measures

The United States and many foreign jurisdictions have enacted or proposed legislative and regulatory changes affecting the healthcare system. The U.S.
government,  state  legislatures,  and  foreign  governments  also  have  shown  significant  interest  in  implementing  cost-containment  programs  to  limit  the
growth of government-paid healthcare costs, including price controls, restrictions on reimbursement, and requirements for substitution of generic products
for branded prescription products.

37

Table of Contents

In  recent  years,  Congress  has  considered  reductions  in  Medicare  reimbursement  levels  for  products  administered  by  physicians.  CMS,  the  agency  that
administers  the  Medicare  and  Medicaid  programs,  also  has  authority  to  revise  reimbursement  rates  and  to  implement  coverage  restrictions  for  some
products. Cost reduction initiatives and changes in coverage implemented through legislation or regulation could decrease utilization of and reimbursement
for  any  approved  products.  While  Medicare  regulations  apply  only  to  drug  benefits  for  Medicare  beneficiaries,  private  payers  often  follow  Medicare
coverage  policy  and  payment  limitations  in  setting  their  own  reimbursement  rates.  Therefore,  any  reduction  in  reimbursement  that  results  from  federal
legislation or regulation may result in a similar reduction in payments from private payers.

The ACA, substantially changed the way healthcare is financed by both governmental and private insurers, and significantly impacts the pharmaceutical
industry.  The  ACA  is  intended  to  broaden  access  to  health  insurance,  reduce  or  constrain  the  growth  of  healthcare  spending,  enhance  remedies  against
healthcare  fraud  and  abuse,  add  new  transparency  requirements  for  healthcare  and  health  insurance  industries,  impose  new  taxes  and  fees  on
pharmaceutical and medical device manufacturers, and impose additional health policy reforms. Among other things, the ACA expanded manufacturers'
rebate  liability  under  the  MDRP  by  increasing  the  minimum  Medicaid  rebate  for  both  branded  and  generic  products,  expanded  the  340B  program,  and
revised  the  definition  of  AMP,  which  could  increase  the  amount  of  Medicaid  rebates  manufacturers  are  required  to  pay  to  states.  The  legislation  also
extended Medicaid rebates, previously due only on fee-for-service Medicaid utilization, to include the utilization of Medicaid managed care organizations
as well and created an alternative rebate formula for certain new formulations of certain existing products that is intended to increase the amount of rebates
due  on  those  products.  On  February  1,  2016,  CMS  issued  final  regulations  to  implement  the  changes  to  the  MDRP  under  the  ACA.  These  regulations
became effective on April 1, 2016. Since that time, there have been significant ongoing efforts to modify or eliminate the ACA. The Tax Act, enacted on
December 22, 2017, repealed the shared responsibility payment for individuals who fail to maintain minimum essential coverage under section 5000A of
the Internal Revenue Code of 1986, as amended, or the Code, commonly referred to as the individual mandate.

Other legislative changes have been proposed and adopted since the passage of the ACA. The Budget Control Act of 2011, among other things, created the
Joint Select Committee on Deficit Reduction to recommend proposals in spending reductions to Congress. The Joint Select Committee did not achieve its
targeted deficit reduction of an amount greater than $1.2 trillion for the fiscal years 2012 through 2021, triggering the legislation's automatic reductions to
several government programs. These reductions included aggregate reductions to Medicare payments to healthcare providers of up to 2.0% per fiscal year,
which went into effect in April 2013. Subsequent legislation extended the 2.0% reduction, on average, to 2030 unless additional Congressional action is
taken.  However,  pursuant  to  the  Coronavirus  Aid,  Relief  and  Economic  Security  Act  ("CARES  Act"),  the  2.0%  Medicare  sequester  reductions  were
suspended from May 1, 2020 through March 31, 2022 due to the COVID-19 pandemic. As of July 2, 2022, the 2.0% sequester reduction resumed. This
sequestration will remain in place through 2030. On January 2, 2013, the American Taxpayer Relief Act was signed into law, which, among other things,
reduced Medicare payments to several types of providers, including hospitals, imaging centers, and cancer treatment centers, and increased the statute of
limitations  period  for  the  government  to  recover  overpayments  to  providers  from  three  to  five  years.  The  Inflation  Reduction  Act  of  2022  (the  "IRA")
contains  substantial  drug  pricing  reforms,  including  the  establishment  of  a  drug  price  negotiation  program  within  the  U.S.  Department  of  Health  and
Human  Services  that  would  require  manufacturers  to  charge  a  negotiated  "maximum  fair  price"  for  certain  selected  drugs  or  pay  an  excise  tax  for
noncompliance, the establishment of rebate payment requirements on manufacturers of certain drugs payable under Medicare Parts B and D to penalize
price  increases  that  outpace  inflation,  and  requires  manufacturers  to  provide  discounts  on  Part  D  drugs.  Substantial  penalties  can  be  assessed  for
noncompliance with the drug pricing provisions in the IRA. The IRA could have the effect of reducing the prices we can charge and reimbursement we
receive  for  our  products,  if  approved,  thereby  reducing  our  profitability,  and  could  have  a  material  adverse  effect  on  our  financial  condition,  results  of
operations, and growth prospects. The effects of the IRA on our business and the pharmaceutical industry in general is not yet known.

The ACA has been subject to challenges in the courts. On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in
its  entirety  because  the  "individual  mandate"  was  repealed  by  Congress.  On  December  18,  2019,  the  Fifth  Circuit  U.S.  Court  of  Appeals  held  that  the
individual mandate is unconstitutional and remanded the case to the Texas District Court to reconsider its earlier invalidation of the entire ACA. An appeal
was taken to the U.S. Supreme Court. On June 17, 2021, the Supreme Court ruled that the plaintiffs lacked standing to challenge the law as they had not
alleged personal injury traceable to the allegedly unlawful conduct. As a result, the Supreme Court did not rule on the constitutionality of the ACA or any
of its provisions.

Further changes to and under the ACA remain possible but it is unknown what form any such changes or any law proposed to replace or revise the ACA
would  take,  and  how  or  whether  it  may  affect  our  business  in  the  future.  We  expect  that  changes  to  the  ACA,  the  Medicare  and  Medicaid  programs,
changes allowing the federal government to directly negotiate prices and changes stemming from other healthcare reform measures, especially with regard
to healthcare access, financing or other legislation in individual states, could have a material adverse effect on the healthcare industry.

38

Table of Contents

At  the  state  level,  legislatures  have  increasingly  passed  legislation  and  implemented  regulations  designed  to  control  pharmaceutical  product  pricing,
including  price  or  patient  reimbursement  constraints,  discounts,  restrictions  on  certain  product  access,  and  marketing  cost  disclosure  and  transparency
measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

We expect that additional federal, state, and foreign healthcare reform measures will be adopted in the future, any of which could limit the amounts that
federal and state governments will pay for healthcare products and services, which could result in limited coverage and reimbursement and reduced demand
for our products, once approved, or additional pricing pressures.

The Foreign Corrupt Practices Act

The Foreign Corrupt Practices Act ("FCPA") prohibits any U.S. individual or business from paying, offering, or authorizing payment or offering anything
of value, directly or indirectly, to any foreign official, political party, or candidate for the purpose of influencing any act or decision of the foreign entity in
order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the United
States to comply with accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all transactions of the
corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations.
Activities that violate the FCPA, even if they occur wholly outside the United States, can result in criminal and civil fines, imprisonment, disgorgement,
oversight, and suspension and debarment from government contracts, and refusal of orders under existing government contracts. Enforcement actions may
be  brought  by  the  Department  of  Justice  or  the  Securities  and  Exchange  Commission  ("SEC"),  and  legislation  has  expanded  the  SEC's  power  to  seek
disgorgement in all FCPA cases filed in federal court and extended the statute of limitations in the SEC enforcement actions in intent-based claims such as
those under FCPA from five years to ten years.

Health Canada

Health Canada is the Canadian federal authority that regulates, evaluates, and monitors the safety, effectiveness, and quality of drugs, medical devices, and
other therapeutic products available to Canadians. Health Canada's regulatory process for review, approval, and regulatory oversight of products is similar
to the regulatory process conducted by the FDA. To initiate clinical testing of a drug candidate in human subjects in Canada, a Clinical Trial Application
("CTA") must be filed with and approved by Health Canada. In addition, all federally regulated trials must be approved and monitored by research ethics
boards ("REB"). The REB studies and approves study-related documents and monitors clinical trial data.

Prior to being given market authorization for a drug product, a manufacturer must present substantive scientific evidence of a product's safety, efficacy, and
quality  as  required  by  the  Food  and  Drugs  Act  and  its  associated  regulations,  including  the  Food  and  Drug  Regulations  ("FDR").  This  information  is
usually  submitted  in  the  form  of  an  NDS.  Health  Canada  reviews  the  submitted  information,  sometimes  using  external  consultants  and  advisory
committees, to evaluate the potential benefits and risks of a drug. If after the review, the conclusion is that the patient benefits outweigh the risks associated
with  the  drug,  the  drug  is  issued  a  Drug  Identification  Number  ("DIN"),  followed  by  a  Notice  of  Compliance  ("NOC"),  which  permits  the  market
authorization  holder  (i.e.,  the  NOC  and  DIN  holder)  to  market  the  drug  in  Canada.  Drugs  granted  an  NOC  may  be  subject  to  additional  post-market
surveillance and reporting requirements.

All establishments engaged in the fabrication, packaging/labeling, importation, distribution, and wholesale of drugs and operation of a testing laboratory
relating to drugs are required to hold a Drug Establishment License ("DEL") to conduct one or more of the licensed activities unless expressly exempted
under the FDR. The basis for the issuance of a DEL is to ensure the facility complies with current GMP as stipulated in the FDR and as determined by a
current  GMP  inspection  conducted  by  Health  Canada.  An  importer  of  pharmaceutical  products  manufactured  at  foreign  sites  must  also  be  able  to
demonstrate that the foreign sites comply with current GMP, and such foreign sites are included on the importer's DEL.

Regulatory  obligations  and  oversight  will  continue  to  follow  after  the  initial  market  approval  of  a  pharmaceutical  product.  For  example,  every  market
authorization  holder  must  report  any  new  information  received  concerning  adverse  drug  reactions,  including  timely  reporting  of  serious  adverse  drug
reactions that occur in Canada and any serious unexpected adverse drug reactions that occur outside of Canada. The market authorization holder must also
notify Health Canada of any new safety and efficacy issues that it becomes aware of after the launch of a product.

The Canadian regulatory approval requirements for new drugs outlined above are similar to those of other major pharmaceutical markets. While the testing
carried  out  in  Canada  is  often  acceptable  for  the  purposes  of  regulatory  submissions  in  other  countries,  individual  regulatory  authorities  may  request
supplementary testing during their assessment of any submission.

39

Table of Contents

Therefore, the clinical testing conducted under Health Canada's regulation may not be accepted by regulatory authorities outside Canada.

Regulation Outside of the United States and Canada

In addition to regulations in the U.S. and Canada, we may be subject to a variety of regulations in foreign jurisdictions that govern, among other things,
clinical trials and any commercial sales and distribution of our product candidates, if approved, either directly or through our distribution partners. Whether
or not we obtain FDA or Health Canada approval for a product candidate, we must obtain the requisite approvals from regulatory authorities in foreign
jurisdictions prior to the commencement of clinical trials or marketing and sale of the product in those countries. The foreign regulatory approval process
includes all of the risks associated with the FDA and Health Canada approval process described above, and the time required to obtain approval in other
countries and jurisdictions might differ from and be longer than that required to obtain FDA or Health Canada approval. Some foreign jurisdictions have a
drug product approval process similar to that in the U.S. or Canada, which requires the submission of a CTA much like the IND application prior to the
commencement of clinical studies. In Europe, for example, a CTA must be submitted to each country's national health authority and an independent ethics
committee, much like the FDA and IRB, respectively. Once the CTA is approved in accordance with a country's requirements, clinical trial development
may proceed. To obtain regulatory approval of a therapeutic product candidate under EU regulatory systems, we would be required to submit a Marketing
Authorisation  Application,  which  is  similar  to  the  NDA,  except  that,  among  other  things,  there  are  country-specific  documentation  requirements.  For
countries outside of the EU, such as countries in Eastern Europe, Latin America or Asia, and recently the United Kingdom, the requirements governing the
conduct of clinical trials, product approval, pricing, and reimbursement vary from country to country. Regulatory approval in one country or jurisdiction
does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction may negatively impact
the regulatory process in other countries. Moreover, some nations may not accept clinical studies performed for U.S. approval to support approval in their
countries or require that additional studies be performed on natives of their countries. In addition, in certain foreign markets, the pricing of drug products is
subject to government control and reimbursement may in some cases be unavailable or insufficient. Resulting prices could be insufficient to generate an
acceptable return to us or any future partner of ours. 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.

HUMAN CAPITAL

As of February 15, 2023, we had 84 employees, the majority of which were full-time employees. None of our employees are represented by a labor union
or  covered  by  a  collective  bargaining  agreement.  In  addition  to  our  employees,  we  engage  various  consultants  to  support  key  areas  of  our  business,
including support of our research and development, manufacturing, and commercialization activities.

Talent Management

Our  human  capital  is  critical  to  the  success  of  our  mission  to  deliver  new  options  for  people  facing  serious  disease  and  conditions.  We  consider  the
performance,  skills,  and  intellectual  capital  of  our  employees  to  be  an  essential  driver  of  this  mission  and  a  key  to  our  future  prospects.  As  such,  we
emphasize  a  number  of  measures  and  objectives  in  attracting,  retaining,  and  developing  our  human  capital,  including,  among  others,  employee  safety,
wellness, engagement, development, diversity and inclusion, and compensation and pay equity. In our employee recruitment process, we adhere to equal
employment  opportunity  policies.  We  are  committed  to  include  diverse  candidates  in  any  pool  of  candidates  from  which  employees  are  chosen.
Additionally,  we  recognize  that  our  employees  perform  best  when  they  know  how  their  work  contributes  to  our  overall  strategy.  To  achieve  this,  we
emphasize open and direct communication through the use of a variety of channels, including company-wide business updates and written communications
from the leadership team.

Compensation and Benefits

Our compensation programs are designed to align our employees' interests with our achievement of our primary business goals. The salaries, bonuses, and
opportunities  for  equity  ownership  provided  to  our  employees  are  competitive  within  our  industry  and  we  engage  outside  compensation  and  benefits
consulting  firms  to  independently  evaluate  the  effectiveness  of  our  compensation  and  benefit  programs  and  to  provide  benchmarking  against  our  peers
within the industry. The benefit options we provide are comprehensive and allow our employees and their families to live healthier and more secure lives.
All full-time employees are eligible for medical, dental, and vision insurance, paid time off, a 401(k) plan, and group life and disability coverage.

Employee Development and Leadership

The  development  of  our  employees  is  critical  to  our  success.  We  believe  that  continued  learning  and  development  is  an  essential  part  to  retaining  our
employees  and  creating  a  culture  of  learning  and  leadership.  We  encourage  employees  to  participate  and  to  take  advantage  of  a  variety  of  learning  and
development resources, including online skills courses, professional development events, and internal and external training programs based on individual
needs.

Diversity and Inclusion

Each  employee  brings  diverse  perspectives,  backgrounds,  and  thinking  styles,  and,  by  embracing  and  celebrating  these  differences,  we  strengthen  our
culture and further our mission. We are committed to preserving and further cultivating our diverse and inclusive workforce, including with respect to our
leadership team and our Board of Directors ("Board"), to ensure an environment where employees feel empowered to achieve their fullest potential. Our
current Board composition represents a deliberate mix of members who have a deep understanding of our business, as well as members who have different
skill sets and points of view. In addition, we are in compliance with the listing requirements of The Nasdaq Stock Market LLC ("Nasdaq") which requires a
public  company  to  have  two  diverse  directors  serve  on  the  board,  including  at  least  one  diverse  director  who  self-identifies  as  female  and  at  least  one
diverse director who self-identifies as an underrepresented minority or LGBTQ+.

We  have  an  active  Diversity,  Equity,  and  Inclusion  ("DEI")  Committee  comprised  of  a  diverse  group  of  employees  responsible  for  designing  and
implementing  specific  initiatives  to  promote  greater  diversity,  equity,  inclusion,  and  belonging.  We  are  proud  of  the  fact  that  our  team  includes  55%  of
employees in ethnic and racial minority groups and also that 45% of our employees are women, both as self-disclosed. We continue to focus on expanding
our commitment to diversity and inclusion across our entire workforce, including working with managers to develop strategies for building diverse teams
and promoting the advancement of employees from diverse backgrounds.

Values

We are guided by a commitment to accountability, respect, collaboration, and inclusivity. These principles drive the values of our employees and agents
that enable us to propel the future of medical science. These values include:

•

Act with urgency — The determination and speed necessary for people seeking new options where none now exist.

• Demonstrate ingenuity — The willingness and ability to explore the unknown, turn over every stone, and forge a new path.

•

•

Show resolve — The drive to find solutions in the face of difficulty and adversity, and the grit to keep going, no matter what.

Be bold — The confidence to challenge conventions and take risks, in the face of both failure and success, and move science in a new direction.

Item 1A.    Risk Factors.

Risk Factors Summary

Investing in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully the risks and
uncertainties described in this section of this Annual Report on Form 10-K. These risks and uncertainties include, but are not limited to, the following:

• We have incurred significant losses and negative cash flows from operations since our inception. We may incur losses over the next several years
and  may  never  achieve  or  maintain  profitability.  These  factors  raise  substantial  doubt  about  our  ability  to  continue  as  a  going  concern  absent
obtaining significant additional funding.

• We will need substantial additional funding. If we are unable to raise capital when needed, we could be forced to delay, reduce, or eliminate our

product development programs or commercialization efforts.

• We will need additional capital in order to enable us to successfully develop our product candidates, and such funding may not be available on
acceptable terms, or at all. Raising additional capital may cause dilution to stockholders, restrict our operations, or require us to relinquish rights to
our technologies or product candidates.

• We  are  substantially  dependent  on  the  success  of  our  product  candidates.  We  cannot  guarantee  that  our  product  candidates  will  successfully

complete development, receive regulatory approval, or be successfully commercialized.

• Our  product  candidates  generated  from  our  modifier  gene  therapy  platform  are  based  on  a  novel  technology  and  face  an  uncertain  regulatory
environment,  which  makes  it  difficult  to  predict  the  time  and  cost  of  product  candidate  development  and  subsequently  obtaining  regulatory
approval.

•

COVAXIN has been evaluated by Bharat Biotech in a Phase 3 clinical trial in India in adults, who were healthy or had stable chronic medical
conditions ages 18 and older, and approved for EUL by the WHO. We have conducted a Phase 2/3 immuno-bridging and broadening clinical trial
and will need to conduct a safety clinical trial to support a BLA submission for COVAXIN for adult use in the United States. We may be unable to
successfully produce and commercialize a vaccine that effectively and safely treats the virus in a timely manner, if at all, and ultimately may be
unable to obtain regulatory approval for adult use in the United States.

• We have obtained the rights to develop, manufacture, and commercialize COVAXIN in Canada and Mexico. We have no experience in obtaining
marketing approvals for, or commercializing products in Canada or Mexico. Our results of operations may be negatively impacted if we are unable
to successfully commercialize COVAXIN in Canada or Mexico.

•

If  we  experience  delays  or  difficulties  in  the  enrollment  of  patients  in  clinical  trials,  our  completion  of  clinical  trials  and  receipt  of  necessary
regulatory approvals could be delayed or prevented.

• We  may  expend  our  limited  resources  to  pursue  a  particular  product  candidate  or  indication  and  fail  to  capitalize  on  product  candidates  or

indications that may be more profitable or for which there is a greater likelihood of success.

• We have no prior experience in the marketing, sale, and distribution of biotechnology products and there can be no assurance that our product

candidates, if approved, will be successfully commercialized.

• We face significant competition from other pharmaceutical and biotechnology companies, academic institutions, government agencies, and other

research organizations. Our operating results will suffer if we fail to compete effectively.

•

If third-party payors do not reimburse patients for our products candidates, if approved, or if reimbursement levels are set too low for us to sell our
product candidates at a profit, our ability to successfully commercialize our product candidates, if approved, and our results of operations will be
harmed.

• We  rely,  and  expect  to  continue  to  rely,  on  third  parties  to  conduct,  supervise,  and  monitor  our  preclinical  studies  and  clinical  trials  we  may
initiate, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such trials or failing to
comply with regulatory requirements.

•

•

If we encounter difficulties in negotiating commercial manufacturing and supply agreements with third-party manufacturers and suppliers of our
product candidates or any product components, our ability to commercialize our product candidates, if approved, would be impaired.

If  the  manufacturers  upon  whom  we  rely  fail  to  produce  our  product  candidates  or  product  components  pursuant  to  the  terms  of  contractual
arrangements with us or fail to comply with stringent regulations applicable to biotechnology

42

Table of Contents

manufacturers,  we  may  face  delays  in  the  development  and  commercialization  of,  or  be  unable  to  meet  demand  for,  our  product  candidates,  if
approved, and may lose potential revenues.

• We may seek to collaborate with third parties for the development or commercialization of our product candidates. We may not be successful in
establishing or maintaining collaborative relationships, any of which could adversely affect our ability to develop and commercialize our product
candidates.

• We  may  be  unable  to  obtain  and  maintain  patent  protection  for  our  technology  and  product  candidates,  or  the  scope  of  the  patent  protection
obtained  may  not  be  sufficiently  broad  or  enforceable,  such  that  our  competitors  could  develop  and  commercialize  technology  and  products
similar or identical to ours, and our ability to successfully commercialize our technology and product candidates may be impaired.

• We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time-consuming,

and unsuccessful.

•

•

•

Certain aspects of our product candidates are protected by patents exclusively licensed from other companies or institutions. If these third parties
terminate their agreements with us or fail to maintain or enforce the underlying patents or licenses thereto, or we otherwise lose our rights to these
patents, our competitive position and our market share in the markets for any of our approved products will be harmed.

Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead
to entrenchment of management.

The trading price of the shares of our common stock could be highly volatile, and purchasers of our common stock could incur substantial losses.

• Our future success depends on our ability to retain key executives and to attract, retain, and motivate qualified personnel.

•

If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate and timely financial statements
could be impaired, investors may lose confidence in our financial reporting, and the trading price of our common stock may decline.

Risks Related to Our Financial Position and Capital Requirements

We have incurred significant losses and negative cash flows from operations since our inception. We may incur losses over the next several years and
may never achieve or maintain profitability. These factors raise substantial doubt about our ability to continue as a going concern absent obtaining
significant additional funding.

Since  inception,  we  have  incurred  significant  net  losses  and  may  continue  to  incur  net  losses  in  the  future.  Our  recurring  losses  from  operations  raise
substantial doubt about our ability to continue as a going concern for the next 12 months from the date of the consolidated financial statements included in
this Annual Report on Form 10-K are issued. As a result, our independent public accounting firm included an explanatory paragraph regarding the same in
its report on this Annual Report on Form 10-K. Substantial doubt about our ability to continue as a going concern may create negative reactions to the price
of our common stock and we may have a more difficult time obtaining financing in the future as a result.

We have not generated significant revenue to date and have funded our operations to date through the sale of common stock, warrants to purchase common
stock, the issuance of convertible notes and debt, and grant proceeds. We incurred net losses of approximately $81.4 million and $58.4 million for the years
ended December 31, 2022 and 2021, respectively. As of December 31, 2022, we had an accumulated deficit of $213.0 million and a cash, cash equivalents,
and investments balance of $90.9 million. This amount will not meet our capital requirements over the next 12 months. We estimate that our cash, cash
equivalents, and investments will enable us to fund our operations into the first quarter of 2024. Based on this estimate, we will need to raise significant
additional capital in order to fund our future operations. We have based this estimate on assumptions that may prove to be wrong, and our operating and
capital requirements may change as a result of many factors currently unknown to us.

There can be no assurance that we will be able to raise sufficient additional capital on acceptable terms or at all. If such additional financing is not available
on satisfactory terms, is not available in sufficient amounts, or we do not have sufficient authorized shares, we may be required to delay, limit, or eliminate
the development of business opportunities and our ability to achieve our business objectives, our competitiveness, and our business, financial condition,
and results of operations will be materially adversely affected. In addition, economic circumstances outside of our control such as a recession or depression
and inflation may reduce our ability to access capital, which could negatively affect our liquidity and ability to continue as a going concern. Further, the
perception that we may not be able to continue as a going concern may cause others to choose not to do business with us due to concerns about our ability
to meet our contractual obligations.

To date, we have not generated any revenues from the sale of products, and absent the realization of sufficient revenues from product sales, if any, of our
current or future product candidates, we may never attain profitability in the future. To date, we have devoted substantially all of our financial resources
and efforts to research and development, including preclinical and clinical studies. We may continue to incur losses from operations in the next several
years as we increase our expenditures in research and development in connection with our ongoing and planned clinical trials and other development and
pre-commercialization activities. Even if we obtain a regulatory approval to market a product candidate, our future revenues will depend upon the size of
any markets in which our product candidates have received such approval, and our ability to achieve sufficient market acceptance, reimbursement from
third-party payors, and adequate market share for our products in those markets.

We anticipate that our expenses will increase in fiscal year 2023 as compared to fiscal year 2022 as we continue to conduct preclinical and clinical activities
with  respect  to  our  product  candidates,  including  the  continuation  and  planned  initiation  of  several  clinical  trials  for  our  product  candidates,  as  well  as
increased headcount, including management personnel to support our research and development, clinical, and business activities, expanded infrastructure,
and increased insurance premiums, among other factors.

Due to the inherently unpredictable nature of preclinical and clinical development and the numerous risks and uncertainties associated with such activities,
we are unable to predict with any certainty the nature or amounts of the costs we will incur, the timelines we will require in our continued development
efforts or the timing, or if, we will be able to achieve profitability.

Additionally, our expenses will also increase if, and, as we:

•

•

initiate preclinical studies and clinical trials for any additional product candidates that we may pursue in the future, particularly if there are any
delays in enrollment of patients in or completing our clinical trials or the development of our product candidates;

seek marketing approvals for product candidates that successfully complete clinical development;

44

Table of Contents

•

•

•

•

•

establish sales, marketing, and distribution capabilities for our product candidates for which we obtain a regulatory approval;

scale up our manufacturing processes and capabilities to support our clinical trials of our product candidates and commercialization of any of our
product candidates for which we obtain a regulatory approval;

expand  our  operational,  financial,  and  management  systems  and  increase  personnel,  including  personnel  to  support  our  clinical  development,
manufacturing, and commercialization efforts, and our operations as a public company;

acquire  other  companies,  products,  product  candidates,  or  technologies,  or  in-license  the  rights  to  other  products,  product  candidates,  or
technologies; and

develop, maintain, expand, and protect our intellectual property portfolio.

Our ability to become and remain profitable depends on our ability to generate revenue. We do not expect to generate revenue that is sufficient to achieve
profitability unless and until we obtain marketing approval for and commercialize one of our product candidates. Our product candidates are in various
stages of preclinical and clinical development or pre-commercialization, and it is unknown whether our near-term efforts to obtain regulatory approval or
commercial sales may be successful or whether additional preclinical, clinical, or manufacturing data may be needed before we obtain regulatory approval
for any candidate. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to
become  profitable  or  inability  to  remain  profitable  would  decrease  the  value  of  our  company  and  could  impair  our  ability  to  raise  capital,  expand  our
business, maintain our research and development efforts, continue or undertake commercialization efforts, diversify our product offerings, or even continue
our operations. A decline in the value of our company could also cause you to lose all or part of your investment.

We have no history of commercializing pharmaceutical products, which may make it difficult for you to evaluate the success of our business to date and
to assess our future viability.

We  are  a  biotechnology  company  and  investment  in  biotechnological  product  development  is  a  highly  speculative  endeavor.  Biotechnology  product
development  entails  substantial  upfront  capital  expenditures  and  there  is  significant  risk  that  any  potential  product  candidate  will  fail  to  demonstrate
adequate efficacy or an acceptable safety profile, to gain any required regulatory approvals or to become commercially viable. To date, our operations have
been limited to organizing and staffing our company, acquiring rights to intellectual property, business planning, raising capital, and developing our product
candidates. We have not yet demonstrated an ability to obtain marketing approvals (only EUA), manufacture a commercial-scale product, or conduct sales
and marketing activities necessary for successful product commercialization. Consequently, any predictions you make about our future success or viability
may not be as accurate as they could be if we had a longer operating history.

We  have  encountered,  and  will  continue  to  encounter,  risks  and  difficulties  frequently  experienced  by  growing  companies  in  a  rapidly  developing  and
changing industry, such as the biotechnological industry, including challenges in forecasting accuracy, determining appropriate investments of our limited
resources, gaining market acceptance of our products, if approved, managing a complex regulatory landscape, and developing new product candidates. Our
current operating model may require changes in order for us to scale our operations efficiently. We will need to transition from a company with a research
and development focus to a company capable of supporting commercial activities. We may not be successful in such a transition. You should consider our
business and prospects in light of the risks and difficulties we face as a company focused on developing products in the fields of biopharmaceuticals and
biotechnology.

We expect our financial condition and operating results to fluctuate significantly from quarter-to-quarter and year-to-year due to a variety of factors, many
of which are beyond our control. Accordingly, you should not rely upon the results of any quarterly or annual periods as indications of future operating
performance.

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

We  expect  to  devote  substantial  financial  resources  to  our  ongoing  and  planned  product  development  activities,  particularly  as  we  continue  the
development  of  and  seek  EUA  or  marketing  approval  for  our  product  candidates  and  any  potential  future  product  candidates,  as  applicable.  As  of
December 31, 2022, we had cash, cash equivalents, and investments of approximately $90.9 million. This amount will not meet our capital requirements
over the next 12 months. We estimate that our cash, cash equivalents, and investments will enable us to fund our operations into the first quarter of 2024.
Based  on  this  estimate,  we  will  need  to  raise  significant  additional  capital  in  order  to  fund  our  future  operations.  We  have  based  this  estimate  on
assumptions

45

Table of Contents

that may prove to be wrong, and our operating and capital requirements may change as a result of many factors currently unknown to us.

Conducting  preclinical  testing  and  clinical  trials  is  a  time-consuming,  expensive,  and  uncertain  process  that  takes  years  to  complete.  We  cannot  predict
when we will be able to generate the necessary data or results required to obtain regulatory approval of products with the market potential sufficient to
enable us to achieve profitability, if ever. Accordingly, we may need to obtain substantial additional funding in connection with our continuing operations.
Our future capital requirements will depend on many factors, including:

•

•

•

•

•

•

•

•

•

•

•

the initiation, progress, timing, costs, and results of clinical trials for our product candidates;

the outcome, timing, and cost of the regulatory approval process for our product candidates;

the costs of manufacturing and commercialization;

the costs related to doing business internationally with respect to the development and commercialization of our product candidates;

the cost of filing, prosecuting, defending, and enforcing our patent claims and other intellectual property rights;

the cost of defending intellectual property disputes, including patent infringement actions brought by third parties against us;

the  costs  of  expanding  infrastructure  to  support  our  development,  commercialization,  and  business  efforts,  including  the  costs  related  to  the
development of a laboratory and manufacturing facility;

the costs involved in recruiting and retaining skilled personnel;

the extent to which we in-license or acquire other products, product candidates, or technologies;

the extent to which we out-license our product candidates; and

the impact of geopolitical turmoil, macroeconomic conditions, social unrest, political instability, terrorism, or other acts of war.

Any  additional  fundraising  efforts  may  divert  our  management  from  their  day-to-day  activities,  which  may  adversely  affect  our  ability  to  develop  and
commercialize our product candidates. Moreover, adequate additional financing may not be available to us on acceptable terms, or at all. If adequate funds
are not available to us on a timely basis, we may be required to delay, limit, reduce, or terminate preclinical studies, clinical trials, or other development
activities  for  one  or  more  of  our  product  candidates  or  delay,  limit,  reduce,  or  terminate  our  establishment  of  sales  and  marketing  capabilities  or  other
activities that may be necessary to commercialize our product candidates.

We  will  need  additional  capital  in  order  to  enable  us  to  successfully  develop  our  product  candidates,  and  such  funding  may  not  be  available  on
acceptable terms, or at all. Raising additional capital may cause dilution to stockholders, restrict our operations, or require us to relinquish rights to
our technologies or product candidates.

We will need additional capital in order to enable us to successfully develop and obtain authorization or approval for our product candidates. Such funding
may  not  be  available  on  acceptable  terms,  or  at  all.  We  expect  to  raise  additional  capital  through  public  and  private  placements  of  equity  and/or  debt,
payments from potential strategic research and development arrangements, sales of assets, government grants, licensing and/or collaboration arrangements
with pharmaceutical companies or other institutions, funding from the government, or funding from other third parties. For example, we anticipate that the
continued  development  of  our  vaccine  candidates  will  require  government  funding  to  support  the  regulatory  pathway  of  such  candidates,  including  the
safety clinical trial that will be used, together with data from our Phase 2/3 immuno-bridging and broadening clinical trial, to support a BLA submission for
COVAXIN, subject to discussions with the FDA. We also intend to work closely with government agencies to obtain funding for the development of our
novel  inhaled  mucosal  vaccine  platform.  In  January  2023,  the  Biden  Administration  announced  that  it  intends  to  extend  the  United  States'  COVID-19
national emergency and public health emergency declarations until May 11, 2023, at which time such emergency declarations will come to an end. It is
currently unclear what effect, if any, the planned cessation of the emergency declarations will have on our ability to obtain government funding to advance
the development of our vaccine product candidates.

If we raise additional funds through collaborations, strategic alliances, licensing arrangements, or marketing and distribution arrangements, we may have to
relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be
favorable to us. Such arrangements may require us to grant rights to develop and market products or product candidates that we would otherwise prefer to
develop and market on our own.

Our management will have broad discretion in the use of the net proceeds from our capital raises, including our February 2022 public offering and our
ongoing at-the-market offering program, and may not use them effectively.

Our management will have broad discretion in the application of the net proceeds from our capital raises (our “Capital Raises”), including our February
2022  public  offering  and  our  ongoing  at-the-market  offering  program,  and  our  stockholders  will  not  have  the  opportunity  as  part  of  their  investment
decision to assess whether the net proceeds from our Capital Raises are being used appropriately. Our stockholders may not agree with our decisions, and
our use of the proceeds may not yield any return on investment for our stockholders. Because of the number and variability of factors that will determine
our use of the net proceeds from our Capital Raises, their ultimate use may vary substantially from their currently intended use. Our failure to apply the net
proceeds  of  our  Capital  Raises  effectively  could  compromise  our  ability  to  pursue  our  growth  strategy  and  we  might  not  be  able  to  yield  a  significant
return, if any, on our investment of those net proceeds. Our stockholders will not have the opportunity to influence our decisions on how to use our net
proceeds  from  our  Capital  Raises.  We  have  and  may  continue  to  invest  the  net  proceeds  from  our  Capital  Raises  in  investment-grade,  interest-bearing
instruments and U.S. government agency securities and treasuries. These investments are not likely to yield a significant return.

Our existing and future indebtedness may limit cash flow available to invest in the ongoing needs of our business.

As of December 31, 2022, we had $2.0 million of outstanding principal borrowings under a Loan Agreement (the "EB-5 Loan Agreement") with EB5 Life
Sciences, L.P. ("EB-5 Life Sciences"), which we are required to repay on the seventh anniversary of the date of the last disbursement under the EB-5 Loan
Agreement (unless terminated earlier pursuant to the terms of the EB-5 Loan Agreement). Our obligations under the EB-5 Loan Agreement are secured by
substantially all of our assets other than our intellectual property. We could in the future incur additional indebtedness beyond our borrowings under the
EB-5 Loan Agreement.

Our existing or future debt could have significant adverse consequences, including:

•

•

•

•

requiring us to dedicate a substantial portion of cash flow from operations or cash on hand to the payment of interest on, and principal of, our debt,
which will reduce the amounts available to fund working capital, capital expenditures, product development efforts, and other general corporate
purposes;

increasing our vulnerability to adverse changes in general economic, industry, and market conditions;

subjecting us to restrictive covenants that may reduce our ability to take certain corporate actions or obtain further debt or equity financing (for
instance, the EB-5 Loan Agreement includes restrictive covenants related to, among other things, the disposition of our property, the incurrence by
us of any additional indebtedness, and the creation by us of any liens or other encumbrances); and

limiting  our  flexibility  in  planning  for,  or  reacting  to,  changes  in  our  business  and  our  industry;  and  placing  us  at  a  competitive  disadvantage
compared to our competitors that have less debt or better debt servicing options.

A failure to comply with the covenants under the EB-5 Loan Agreement, including covenants to take or avoid specific actions as set forth above, could
result in an event of default and acceleration of amounts due. If an event of default occurs and EB-5 Life Sciences accelerates the amounts due under the
EB-5 Loan Agreement, we may not be able to make accelerated payments, and EB-5 Life Sciences could seek to enforce security interests in the collateral
securing such indebtedness.

In order to satisfy our current and future debt service obligations, we will be required to raise funds from external sources. We may be unable to arrange for
additional financing to pay the amounts due under our existing debt. Funds from external sources may not be available on acceptable terms, if at all. Our
failure to satisfy our current and future debt obligations could adversely affect our financial condition and results of operations.

Our ability to utilize our tax net operating losses is uncertain.

We have incurred significant net operating losses since our inception. As of December 31, 2022, we had U.S. federal net operating loss carryforwards of
approximately $200.5 million. Our ability to utilize these net operating losses to offset future tax liabilities depends on the successful development of our
product candidates and future financial performance.

Additionally, our net operating losses may be subject to Section 382 of the Internal Revenue Code of 1986, as amended ("Section 382"). Generally, if an
ownership change occurs within three years of the closing date of an entity's most recent change in control transaction, any existing net operating losses and
certain built-in losses would be subject to an additional limitation, pursuant to Section 382. Change in control as defined by Section 382 occurs when there
is an ownership change among stockholders owning directly or indirectly 5% or more of our common stock, as well as an aggregate ownership change

47

Table of Contents

with respect to such stockholders of more than 50% of our common stock. We have not yet conducted a comprehensive study to assess whether a change of
ownership as defined by Section 382 has occurred since our inception. If it is determined that we are unable to use our net operating losses to reduce future
tax liabilities, our financial condition, results of operations, and cash flows may be adversely affected.

We may be subject to future changes in tax legislation or exposure to additional tax liabilities that may adversely affect our financial condition, results
of operations, and cash flows.

We  are  subject  to  taxes  in  the  United  States  as  well  as  the  foreign  jurisdictions  where  our  subsidiaries  are  organized.  Due  to  economic  and  political
conditions, tax rates, tax laws, and other non-tax legislation, we may experience significant impacts as a result of prospective changes. Our future effective
tax rates may be affected by changes in the valuation of deferred tax assets and liabilities, changes in available tax credits or tax deductions, as well as
changes in tax law and other non-tax laws, or their interpretation.

Our tax returns and other tax matters are subject to examination by applicable tax authorities and governmental bodies. We regularly assess the likelihood
of an adverse outcome resulting from examination, in order to determine any resulting impact to our provision for income taxes or deferred tax balances.
There can be no assurance as to the outcome of these examinations. As such, if we were to sustain an adjustment as a result of a tax examination in excess
of amounts previously accrued, our financial condition could be adversely affected.

Risks Related to Our Business and the Development of Our Product Candidates

We are substantially dependent on the success of our product candidates. We cannot guarantee that our product candidates will successfully complete
development, receive regulatory approval, or be successfully commercialized.

We have invested a significant portion of our efforts and financial resources in the development of our product candidates. We currently have no products
authorized  or  approved  for  which  we  have  successfully  commercially  distributed,  and  we  have  not  generated  revenues  from  sales  of  any  products.  Our
business  and  our  ability  to  generate  revenues  in  the  near  term  depends  entirely  on  the  successful  development,  approval,  and  commercialization  of  our
product candidates, which may never occur. If the results or timing of regulatory filings, the regulatory process, regulatory developments, clinical trials or
preclinical studies, or other activities, actions, or decisions related to our product candidates do not meet our or others' expectations, the market price of our
common stock could decline significantly.

Our  product  candidates  are  susceptible  to  the  risks  of  failure  inherent  at  any  stage  of  product  development,  including  the  appearance  of  unexpected  or
unacceptable adverse events or failure to demonstrate efficacy in clinical trials. Further, our product candidates may not receive regulatory approval even if
they are successful in clinical trials, and our product candidates may not be successfully commercialized even if they receive regulatory approval.

Our product candidates are in various stages of development ranging from preclinical development to pre-commercialization.

The success of our product candidates and our ability to generate revenues from our product candidates, if approved, will depend on many factors including
our ability to:

•

•

•

•

•

•

•

•

complete and obtain favorable results from our clinical trials and preclinical studies with respect to our product candidates;

apply for and receive marketing approval from the applicable regulatory authorities;

receive regulatory approval for claims that are necessary or desirable for successful marketing;

receive approval for our manufacturing processes and facilities from the applicable regulatory authorities;

recruit and enroll qualified patients for clinical trials with respect to our product candidates in a timely manner;

expand and maintain a workforce of experienced scientists and others with experience in relevant technologies to continue to develop our product
candidates;

hire, train, and deploy marketing and sales representatives or contract with a third-party for marketing and sales representatives to commercialize
product candidates in the United States and key foreign markets;

launch and create market demand for our product candidates, if approved, through marketing and sales activities, and any other arrangements to
promote these product candidates that we may otherwise establish;

48

Table of Contents

•

•

achieve market acceptance of our product candidates by patients, the medical community, and third-party payors;

effectively compete with other therapies and establish a market share;

• maintain a continued acceptable safety and efficacy profile of our product candidates, if approved, following commercial launch;

•

achieve appropriate reimbursement, pricing, and payment coverage for our product candidates, if approved;

• manufacture product candidates in sufficient quantities and at acceptable quality and manufacturing cost to meet commercial demand at launch

and thereafter;

•

•

•

establish and maintain agreements with wholesalers, distributors, and group purchasing organizations on commercially reasonable terms;

pursue  partnerships  with,  or  offer  licenses  to,  qualified  third  parties  to  promote  and  sell  product  candidates,  if  approved,  in  domestic  and  key
foreign markets where we receive marketing approval;

develop our product candidates for additional indications or for use in broader patient populations;

• maintain patent and trade secret protection and regulatory exclusivity for our product candidates; and

•

qualify for, identify, register, maintain, enforce, and defend intellectual property rights and claims covering our products and intellectual property
portfolio; and not infringe on others’ intellectual property rights.

To the extent we are not able to do any of the foregoing, our business may be materially harmed. If we do not receive FDA or other applicable foreign
regulatory approval for, and successfully commercialize our product candidates, we will not be able to generate revenue from these product candidates in
the United States or other key foreign markets for the foreseeable future or at all.

Our  product  candidates  generated  from  our  modifier  gene  therapy  platform  are  based  on  a  novel  technology  and  face  an  uncertain  regulatory
environment, which makes it difficult to predict the time and cost of product candidate development and subsequently obtaining regulatory approval.

A substantial portion of our product research and development efforts is centered around our modifier gene therapy platform. The regulatory approval and
successful commercialization of OCU400, OCU410, and OCU410ST depend on the successful development of this platform. There can be no assurance
that any development problems we experience in the future related to our modifier gene therapy platform will not cause significant delays or unanticipated
costs,  or  that  such  development  problems  can  be  solved.  The  clinical  trial  requirements  of  the  FDA,  the  EMA,  and  other  regulatory  agencies,  and  the
criteria used by these regulators to determine the safety and efficacy of a product candidate vary substantially according to the type, complexity, novelty,
and intended use and market of such product candidates. The regulatory approval process for novel product candidates such as these can be more expensive
and take longer than for other, better known, or extensively studied pharmaceuticals or other product types.

Regulatory requirements governing gene and cell therapy products have changed frequently and may continue to change in the future. For example, the
FDA  established  the  Office  of  Tissues  and  Advanced  Therapies  within  its  Center  for  Biologics  Evaluation  and  Research  ("CBER")  to  consolidate  the
review of gene therapy and related products, and the Cellular, Tissue and Gene Therapies Advisory Committee to advise CBER on its review. Gene therapy
clinical  trials  conducted  at  institutions  that  receive  funding  for  recombinant  deoxyribonucleic  acid  ("DNA")  research  from  the  NIH  are  also  subject  to
review  by  the  NIH  Novel  and  Exceptional  Technology  and  Research  Advisory  Committee  ("NExTRAC"),  formerly  the  Recombinant  DNA  Advisory
Committee,  which  now  focuses  on  emerging  areas  of  research  including,  but  not  restricted  to,  technologies  surrounding  advances  in  recombinant  or
synthetic nucleic acid research. Although the FDA decides whether individual gene therapy protocols may proceed, it is possible the NExTRAC review
process,  which  is  still  being  implemented,  could  delay  the  initiation  of  a  clinical  trial,  even  if  the  FDA  has  reviewed  the  trial  design  and  details  and
approved its initiation. Before a clinical trial can begin at a study site, the institution’s IRB and its IBC have to review the proposed clinical trial to assess
the  safety  of  the  trial.  In  addition,  adverse  developments  in  clinical  trials  of  gene  therapy  products  conducted  by  others  may  cause  the  FDA  or  other
regulatory bodies to change the requirements for approval of any of our product candidates.

These regulatory review committees and advisory groups and the new guidelines they promulgate may lengthen the regulatory review process, require us to
perform  additional  studies,  increase  our  development  costs,  lead  to  changes  in  regulatory  positions  and  interpretations,  delay  or  prevent  approval  and
commercialization  of  our  product  candidates,  or  lead  to  significant  post-approval  limitations  or  restrictions.  As  we  advance  our  gene  therapy  product
candidates, we will be required to consult with these regulatory and advisory groups, and comply with applicable guidelines. If we fail to do so, we may be
required to delay or

49

Table of Contents

discontinue development of our gene therapy product candidates. These additional processes may result in a review and approval process that is longer than
we otherwise would have expected for orphan ophthalmology product candidates. Delay or failure to obtain, or unexpected costs in obtaining the regulatory
approval necessary to bring a potential product to market could decrease our ability to generate sufficient product revenue to maintain our business.

Existing data on the safety and efficacy of gene therapy is very limited and sometimes include historically poor clinical efficacy of previous non-replicating
gene therapy products. In addition, there have been publicized safety issues associated with previous gene therapy products in third-party clinical trials,
including patient deaths. The results of preclinical and clinical trials performed for our product candidates will not definitively predict safety or efficacy in
humans. OCU400, OCU410, and OCU410ST use an AAV vector. Possible serious side effects of other viral vector-based gene therapies in general include
uncontrolled  viral  infections  and  the  development  of  cancer,  particularly  lymphoma  or  leukemia.  The  risk  of  insertional  mutagenesis  or  oncogenesis
remains a significant concern for gene therapy, and we cannot provide any assurance that it will not occur in any of our ongoing or planned clinical trials
with respect to our product candidates based on our modifier gene therapy platform. There is also the potential risk of delayed adverse events following
exposure to gene therapy products due to persistent biological activity of the genetic material or other components of products used to carry the genetic
material.  Potential  procedure-related  adverse  reactions,  including  inflammation,  can  also  occur.  If  any  such  adverse  events  occur  during  clinical  trials,
further advancement of such clinical trials could be halted or delayed, which would have a material adverse effect on our business and operations.

Finally, the public's attitude may be influenced by claims that gene therapy technology is unsafe, unethical, or immoral. If we are unable to convincingly
demonstrate the safety and efficacy of our product candidates arising from our gene modifier platform, our product candidates, even if approved by the
FDA or foreign regulatory authorities, may not gain the acceptance of the public or the medical community.

COVAXIN  has  been  evaluated  by  Bharat  Biotech  in  a  Phase  3  clinical  trial  in  India  in  adults,  who  were  healthy  or  had  stable  chronic  medical
conditions ages 18 and older, and approved for EUL by the WHO. We have conducted a Phase 2/3 immuno-bridging and broadening clinical trial and
will  need  to  conduct  a  safety  clinical  trial  to  support  a  BLA  submission  for  COVAXIN  for  adult  use  in  the  United  States.  We  may  be  unable  to
successfully produce and commercialize a vaccine that effectively and safely treats the virus in a timely manner, if at all, and ultimately may be unable
to obtain regulatory approval for adult use in the United States.

We cannot predict the speed at which we will be able to obtain regulatory marketing approval for adult use for COVAXIN in the United States, if at all. In
February 2021, we entered into the Covaxin Agreement with Bharat Biotech, pursuant to which we obtained an exclusive right and license under certain of
Bharat Biotech’s intellectual property rights, with the right to grant sublicenses, to develop, manufacture, and commercialize COVAXIN, a whole-virion
inactivated COVID-19 vaccine candidate, in the United States, its territories and possessions. Our development efforts with respect to the U.S. market are
still  ongoing  and  remain  uncertain.  We  completed  our  Phase  2/3  immuno-bridging  and  broadening  clinical  trial  for  COVAXIN  in  the  United  States  for
adults ages 18 years and older to support a BLA submission and in January 2023, we announced top-line results from our Phase 2/3 immuno-bridging and
broadening clinical trial in the United States evaluating COVAXIN for adults ages 18 years and older. The clinical trial was designed to evaluate whether
the immune response observed in participants in Bharat Biotech's completed Phase 3 clinical trial in India is similar to a demographically representative,
adult population in the United States. The clinical trial enrolled 419 adult participants that were randomized to receive either two doses of COVAXIN or a
placebo, 28 days apart. Immune responses were adjusted for differences between the U.S. and Indian cohorts in baseline neutralizing antibody, body mass
index, gender, and age. Both co-primary immunogenicity endpoints were met, with the 95% CI for the propensity score-adjusted geometric mean titer ratio
being well above the non-inferiority limit of 0.667. The 95% CI for the propensity score-adjusted difference in seroconversion rates were well above the
non-inferiority limit of (10)%. There were no deaths, related potential immune mediated medical conditions, or related adverse events of special interest.
Additionally, there were no cases of myocarditis, pericarditis, thrombotic events, or Guillain-Barré syndrome. There were no cases of adverse events and
SAEs  related  to  the  vaccination.  30  medically  attended  adverse  events  in  18  subjects  and  two  SAEs  in  one  subject  were  reported,  all  of  which  were
considered  unrelated  to  the  vaccination.  Data  from  the  Phase  2/3  immuno-bridging  and  broadening  clinical  trial  and  a  safety  clinical  trial,  subject  to
discussions with the FDA, will be utilized to support a BLA submission.

We plan to initiate the adult safety clinical trial, subject to discussions with the FDA, and intend to work with government agencies in the United States to
obtain  funding  to  do  so.  There  can  be  no  assurances  that  the  results  of  any  clinical  trials  we  may  conduct  will  resemble  the  results  obtained  by  Bharat
Biotech  in  their  clinical  trials  in  India.  Any  results  from  further  clinical  testing  by  Bharat  Biotech  or  by  us  may  raise  new  questions  and  require  us  to
redesign clinical trials, including revising proposed endpoints or adding new clinical trial sites or cohorts of subjects. In addition, the FDA’s analysis of any
clinical data may differ from our interpretation and the FDA may require that we conduct additional analysis or trials. Further, ongoing

50

Table of Contents

clinical testing by Bharat Biotech and administration of COVAXIN in authorized or approved jurisdictions may demonstrate that the vaccine candidate is
less  effective  than  currently  believed,  including  against  new  or  emerging  variants,  or  has  an  unacceptable  safety  profile,  which  would  have  a  negative
impact on our development efforts in the United States.

The  clinical  trials  to  be  used  as  the  basis  for  a  BLA  submission  must  meet  certain  criteria  related  to  trial  participant  demographics  and  manufacturing
standards. BLA approval is a lengthy development process. Moreover, evolving or changing plans or priorities at the FDA, including changes based on new
knowledge  of  COVID-19,  the  effectiveness  of  other  available  vaccines  for  COVID-19,  the  extent  to  which  the  U.S.  population  has  been  vaccinated  or
obtained natural immunity, emerging variants of SARS-CoV-2, and how the new variants of the disease affect the human body, may significantly affect the
regulatory development and timeline for COVAXIN in the United States.

We  have  obtained  the  rights  to  develop,  manufacture,  and  commercialize  COVAXIN  in  Canada  and  Mexico.  We  have  no  experience  in  obtaining
marketing approvals for, or commercializing products in Canada or Mexico. Our results of operations may be negatively impacted if we are unable to
successfully commercialize COVAXIN in Canada or Mexico.

In June 2021, we entered into an amendment to the Covaxin Agreement with Bharat Biotech that provided us with the rights to develop and commercialize
COVAXIN in Canada. In order to market and sell COVAXIN in Canada, we must obtain marketing approval for COVAXIN from Health Canada and must
comply  with  that  agency’s  regulatory  requirements.  Effective  September  16,  2020,  COVID-19  vaccine  products  in  Canada  were  being  evaluated  for
approval under the Interim Order. The Interim Order provided temporary regulatory tools to expedite the approval of drugs and vaccines developed for the
treatment  of  COVID-19.  In  July  2021,  we  completed  our  rolling  submission  to  Health  Canada  for  COVAXIN.  The  rolling  submission  process,  which
permits companies to submit safety and efficacy data and information as they become available, was recommended and accepted under the Interim Order
and  transitioned  to  an  NDS  for  COVID-19.  In  August  2022,  we  withdrew  our  NDS  based  on  discussions  with  Health  Canada  and  are  evaluating  the
requirements for resubmitting an updated NDS.

In April 2022, we entered into a second amendment to the Covaxin Agreement that provided us with the rights to develop, manufacture, and commercialize
COVAXIN in Mexico. COFEPRIS previously authorized emergency use for COVAXIN for adults ages 18 years and older, which remains active. We are
also in discussions with CONACYT in Mexico regarding our submission for EUA for COVAXIN for pediatric use in ages five to 18 years.

The clinical trials of COVAXIN conducted by Bharat Biotech in India and our Phase 2/3 immuno-bridging and broadening clinical trial conducted in the
United States may not be sufficient to support an application for marketing approval in Canada or Mexico. Accordingly, seeking regulatory approval in
these jurisdictions could result in difficulties and costs for us and require additional preclinical studies or clinical trials which could be costly and time-
consuming. We do not have regulatory approvals for product candidates in any jurisdiction and we do not have experience in obtaining regulatory approval
in Canada or Mexico. We, or any collaborators, may not obtain approval for COVAXIN from the regulatory agencies in these jurisdictions on a timely
basis, if at all. Even if we obtain approval from the FDA for COVAXIN, approval by the FDA does not ensure approval by regulatory authorities in other
countries  or  jurisdictions,  including  in  Canada  or  Mexico,  or  vice  versa.  Ultimately,  we  may  not  receive  the  necessary  approval  to  commercialize
COVAXIN in Canada or Mexico. Although, COFEPRIS authorized emergency use for COVAXIN for adults ages 18 years and older, such EUA may be
revoked at any time and is not a replacement for regulatory approval. We have not sold or administered any doses of COVAXIN under such EUA to date.

Newly emerging SARS-CoV-2 variants could reduce the immunogenicity and effectiveness of COVAXIN as a potential COVID-19 vaccine.

Multiple variants of the virus that causes COVID-19 have been documented in the United States and globally over the course of the pandemic. New and
emerging  SARS-CoV-2  variants  could  be  less  affected  by  the  immune  responses  generated  by  COVAXIN  in  the  vaccine  recipients  and  therefore  could
reduce the overall efficacy of our intramuscular vaccine candidate in controlling COVID-19.

The  ongoing  COVID-19  pandemic  and  actions  taken  in  response  to  it  may  result  in  disruptions  to  our  business  operations,  which  would  have  a
materially adverse effect on our business, financial position, operating results, and cash flows.

In December 2019, the strain of coronavirus, SARS-CoV-2, causing the disease known as COVID-19, was reported to have surfaced in Wuhan, China. In
March  2020,  the  WHO  declared  the  COVID-19  outbreak  a  global  pandemic.  Since  being  discovered,  new  variants  of  SARS-CoV-2  have  emerged.  If
COVID-19 continues to spread in the United States and elsewhere, it may impact our business and development activities, including, but not limited to,
delay of enrollment and ultimate completion of current clinical trials and delay of enrollment in any clinical trials that we have planned or otherwise may
initiate in the future, strain on our suppliers and other third parties, possibly resulting in supply disruptions of our product candidates

51

for  preclinical  development  and  clinical  trials,  and  the  ability  to  raise  capital  when  needed  on  acceptable  terms,  if  at  all.  The  COVID-19  pandemic
continues  to  impact  the  global  supply  chain,  causing  disruptions  to  service  providers,  logistics,  and  the  flow  and  availability  of  supplies  and  products.
Disruptions in our operations or supply chain, whether as a result of government intervention, restricted travel, quarantine requirements, or otherwise, could
negatively  impact  our  ability  to  proceed  with  our  clinical  trials,  preclinical  development,  and  other  activities  and  delay  our  ability  to  receive  product
approval and generate revenue. In addition, the continued spread of COVID-19 may lead to severe disruption and volatility in the global capital markets,
which could increase our cost of capital and adversely affect our ability to access the capital markets. It is possible that the continued spread of COVID-19
could  cause  an  economic  slowdown  or  recession  or  cause  other  unpredictable  events,  each  of  which  could  adversely  affect  our  business,  results  of
operations, or financial condition.

The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time consuming, and inherently unpredictable. If we
are not able to obtain, or if there are delays in obtaining required regulatory approvals, we will not be able to commercialize our product candidates as
expected, and our ability to generate revenue will be materially impaired.

The research, testing, manufacturing, labeling, approval, selling, marketing, and distribution of pharmaceutical products are subject to extensive regulations
by  the  FDA  and  other  regulatory  authorities,  which  regulations  differ  from  country  to  country.  The  time  required  to  obtain  approval  by  the  FDA  and
comparable foreign authorities is unpredictable but typically takes many years following the commencement of clinical trials. The outcome of the approval
process is inherently uncertain and depends upon numerous factors, including the substantial discretion of the regulatory authorities. This is especially true
for  rare  and/or  complicated  diseases.  Failure  can  occur  at  any  time  during  the  clinical  trial  process.  We  cannot  predict  if  or  when  we  might  receive
regulatory approvals for any of our product candidates currently under development. Any delay in our obtaining or our failure to obtain required approvals
could materially adversely affect our ability to generate revenue from the particular product candidate, which likely would result in significant harm to our
financial position and adversely impact our stock price.

Securing marketing approval requires the submission of extensive preclinical and clinical data and supporting information to regulatory authorities for each
therapeutic indication to establish the product candidate’s safety and efficacy for that indication. We may be unable to design and execute a clinical trial to
support  marketing  approval.  Securing  marketing  approval  also  requires  the  submission  of  information  about  the  product  manufacturing  process  to,  and
inspection of manufacturing facilities and clinical trial sites by the regulatory authorities. Regulatory authorities have substantial discretion in the approval
process and may refuse to accept any application or may decide that our data is insufficient for approval and require additional preclinical, clinical, or other
studies. The number and types of preclinical studies and clinical trials that will be required for regulatory approval also varies depending on the product
candidate, the disease or condition that the product candidate is designed to address, and the regulations applicable to any particular product candidate. The
FDA or other similar regulatory authorities may determine that our product candidates are not effective or only moderately effective (e.g., studies may not
produce  the  necessary  result  on  all  study  endpoints),  that  our  studies  failed  to  reach  the  necessary  level  of  statistical  significance,  or  that  our  product
candidates have undesirable or unintended side effects, toxicities, or other characteristics that preclude us from obtaining marketing approval or prevent or
limit commercial use.

We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to receive marketing approval
or commercialize our product candidates, including:

•

regulators, including the FDA and the NIH, or IRBs or IBCs may not authorize us or our investigators to commence or continue a clinical trial,
conduct a clinical trial at a prospective trial site, or amend trial protocols, or regulators, IRBs, or IBCs may require that we modify or amend our
clinical trial protocols;

• we may experience delays in reaching, or fail to reach, agreement on acceptable clinical trial contracts or clinical trial protocols with prospective

trial sites and our CDMOs;

•

•

•

the number of patients required for clinical trials of our product candidates may be larger than we anticipate, enrollment in these clinical trials may
be slower than we anticipate, or participants may drop out of these clinical trials, or be lost to follow-up at a higher rate than we anticipate;

our third-party contractors may fail to comply with regulatory requirements or the clinical trial protocol, or meet their contractual obligations to us
in a timely manner, or at all, or we may be required to engage in additional clinical trial site monitoring;

us, the regulators, IRBs, or IBCs may require the suspension or termination of clinical research for various reasons, including noncompliance with
regulatory  requirements  or  a  finding  that  the  participants  are  being  exposed  to  unacceptable  health  risks,  undesirable  side  effects,  or  other
unexpected characteristics (alone or in combination with

52

Table of Contents

other products) of the product candidate, or due to findings of undesirable effects caused by a chemically or mechanistically similar therapeutic or
therapeutic candidate;

•

•

•

changes in marketing approval policies or regulations, or changes in or the enactment of additional statutes or regulations, during the development
period rendering our data insufficient to obtain marketing approval and requiring us to conduct additional studies;

the cost of clinical trials of our product candidates may be greater than we anticipate or we may have insufficient funds for a clinical trial or to pay
the substantial user fees required by the FDA upon the filing of a marketing application;

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;

• we may have delays in adding new investigators or clinical trial sites, or we may experience a withdrawal of clinical trial sites;

•

•

•

•

•

•

•

patients that enroll in our studies may misrepresent their eligibility or may otherwise not comply with the clinical trial protocol, resulting in the
need to drop the patients from the study, increase the needed enrollment size for the study, or extend the study’s duration;

the FDA or comparable foreign regulatory authorities may disagree with our study design, including endpoints, or our interpretation of data from
preclinical studies and clinical trials or find that a product candidate’s benefits do not outweigh its safety risks;

the FDA or comparable foreign regulatory authorities may not accept data from studies with clinical trial sites in foreign countries;

the FDA or comparable foreign regulatory authorities may disagree with our intended indications;

the  FDA  or  comparable  foreign  regulatory  authorities  may  fail  to  approve  or  subsequently  find  fault  with  the  manufacturing  processes  or  our
contract manufacturer’s manufacturing facility for clinical and future commercial supplies;

the  data  collected  from  clinical  trials  of  our  product  candidates  may  not  be  sufficient  to  the  satisfaction  of  the  FDA  or  comparable  foreign
regulatory authorities to support the submission of a marketing application, or other comparable submissions in foreign jurisdictions, or to obtain
regulatory approval in the United States or elsewhere;

the FDA or comparable foreign regulatory authorities may take longer than we anticipate to make a decision on our product candidates; and

• we may not be able to demonstrate that a product candidate provides an advantage over current standards of care or current or future competitive

therapies in development.

Significant  delays  relating  to  any  preclinical  or  clinical  trials  also  could  shorten  any  periods  during  which  we  may  have  the  exclusive  right  to
commercialize our product candidates, if approved, or allow our competitors to bring products to market before we do. This may prevent us from receiving
marketing approvals and impair our ability to successfully commercialize our product candidates, if approved, and may harm our business and results of
operations. In addition, many of the factors that cause, or lead to, delays in clinical trials may ultimately lead to the denial of marketing approval of any of
our product candidates. If any of this occurs, our business, financial condition, results of operations, and prospects will be materially harmed.

The  failure  to  comply  with  FDA  and  comparable  foreign  regulatory  requirements  may,  either  before  or  after  product  approval,  if  any,  subject  us  to
administrative or judicially imposed sanctions, including:

•

•

restrictions on our ability to conduct clinical trials, including full or partial clinical holds on ongoing or planned trials;

restrictions on our products, manufacturers, or manufacturing process;

• warning letters, Form 483s, or untitled letters alleging violations;

•

•

•

•

•

civil and criminal penalties;

injunctions;

suspension or withdrawal of regulatory approvals;

product seizures, detentions, or import bans;

voluntary or mandatory product recalls and publicity requirements;

53

Table of Contents

•

•

•

total or partial suspension of production;

imposition of restrictions on operations, including costly new manufacturing requirements; and

refusal to approve pending marketing applications or supplements to approved marketing applications.

Even if we were to obtain regulatory approval of a product candidate, the FDA or comparable foreign regulatory authorities may grant approval for fewer
or more limited indications, populations, or uses than we request, may require significant safety warnings, including black box warnings, contraindications,
and  precautions,  may  grant  approval  contingent  on  the  performance  of  costly  post-marketing  clinical  trials,  surveillance,  restrictions  on  use  or  other
requirements, including a REMS to monitor the safety or efficacy of the product, or may approve a product candidate with a label that does not include the
labeling  claims  necessary  or  desirable  for  the  successful  commercialization  of  that  product  candidate.  Any  of  these  scenarios  could  compromise  the
commercial prospects for our product candidates.

As an organization, we have limited experience in the development, manufacturing, distribution, or commercialization of a vaccine candidate.

We have limited experience in the development of vaccine candidates and have never undertaken the manufacturing, distribution, or commercialization of a
vaccine  candidate,  and  we  may  be  unable  to  obtain  regulatory  authorization  or  approval.  Additionally,  development  of  an  effective  vaccine  candidate
depends on the success of our and our partner’s manufacturing capabilities. We have not previously ramped our organization for a commercial launch of
any  product  and  doing  so  in  a  pandemic  environment  with  an  urgent,  critical  global  need  creates  additional  challenges  such  as  clinical  trials,  licensing,
distribution  channels,  intellectual  property  disputes  or  challenges,  and  the  need  to  establish  teams  of  people  with  the  relevant  skills.  We  may  also  face
challenges with sourcing a sufficient amount of raw materials to support the demand for a vaccine, including any potential import issues and the ability of
our collaboration partner, Bharat Biotech, to successfully respond to the deficiencies identified in an inspection conducted by the WHO. We may be unable
to effectively create a supply chain for our vaccines that will adequately support demand. Furthermore, there are no assurances that any vaccine candidate
would be authorized or approved at all or for inclusion in government stockpile programs or transition to the private market, which may be material to the
commercial success of a vaccine product candidate. There can also be no assurance that we will be able to obtain the required funding from government
agencies to continue the development of our vaccine candidates.

The development and manufacture of biologics is a complex process and entails particular risks.

OCU200 is our novel biologic designed to treat retinal diseases. The process of developing and manufacturing biologics is complex, highly regulated, and
subject  to  multiple  risks,  and  we  have  no  experience  in  successfully  developing,  manufacturing,  or  commercializing  a  biologics  product.  The
manufacturing of biologics is highly susceptible to product loss due to contamination, equipment failure, improper installation or operation of equipment,
vendor  or  operator  error,  inconsistency  in  yields,  variability  in  product  characteristics,  and  difficulties  in  scaling  the  production  process.  Even  minor
deviations from normal manufacturing processes could result in reduced production yields, product defects and other supply disruptions, and higher costs.

The raw materials required in our third-party vendors’ manufacturing processes are derived from biological sources. We cannot assure you that our third-
party vendors have, or will be able to obtain on commercially reasonable terms, or at all, sufficient rights to these materials derived from biological sources.
Such raw materials are difficult to procure and may also be subject to contamination or recall. If microbial, viral, or other contaminations are discovered at
the facilities of our manufacturer, such facilities may need to be closed for an extended period of time to investigate and remedy the contamination, which
could delay clinical trials, result in higher costs of drug product, and adversely harm our business. A material shortage, recall, or restriction on the use of
biologically derived substances in the manufacture of our product candidates could adversely impact or disrupt the clinical and commercial manufacturing
of our product candidates, which could materially and adversely affect our operating results and development timelines. In addition, the U.S. government
may impose restrictions on goods, including biologically derived substances, manufactured in or imported from China. This could have a material adverse
effect on our business and operations.

In addition, our biologic product candidates may expose us to additional potential product liability claims. The development of biologic products entails a
risk of additional product liability claims because of the risk of transmitting disease to human recipients, and substantial product liability claims may be
asserted against us as a result.

OCU400  has  received  ODDs  from  the  FDA  and  OMPD  from  the  EC.  However,  there  is  no  guarantee  that  we  will  be  able  to  maintain  these
designations, receive this designation for any of our other product candidates, or receive or maintain any corresponding benefits, including periods of
exclusivity.

54

Table of Contents

We have obtained from the FDA Office of Orphan Products, ODDs for OCU400 for NR2E3-related RP and LCA and had previously received ODDs for
the treatment of the following disease genotypes: NR2E3, RHO, CEP290, and PDE6ß  mutation-associated  inherited  retinal  degenerations.  OCU400  has
additionally received OMPD from the EC, based on the recommendation of the EMA, for RP and LCA. We may also seek ODD or OMPD for our other
product  candidates,  as  appropriate.  While  these  ODDs  and  OMPDs  provide  us  with  certain  advantages,  they  neither  shorten  the  development  time  or
regulatory review time of a product candidate nor give the product candidate any advantage in the regulatory review or approval process.

Generally, if a product candidate with ODD or OMPD subsequently receives marketing approval before another product considered by the FDA or EMA to
be the same, for the same orphan indication, the product is entitled to a period of marketing exclusivity, which precludes the FDA or EMA from approving
another marketing application for the same drug or biologic for the same indication for a specified time period. The applicable period is seven years in the
United States and 10 years in Europe. The European exclusivity period can be reduced to six years if a product no longer meets the criteria for OMPD or if
the product is sufficiently profitable so that market exclusivity is no longer justified.

We  may  not  be  able  to  obtain  any  future  ODDs  or  OMPDs  that  we  apply  for,  ODDs  or  OMPDs  do  not  guarantee  that  we  will  be  able  to  successfully
develop our product candidates, and there is no guarantee that we will be able to maintain any ODDs or OMPDs that we receive. For instance, ODDs may
be revoked if the FDA finds that the request for designation contained an untrue statement of a material fact or omitted material information, or if the FDA
finds that the product candidate was not eligible for designation at the time of the submission of the request.

Moreover, even if we are able to receive and maintain ODDs or OMPDs, we may ultimately not receive any period of regulatory exclusivity if our product
candidates  are  approved.  For  instance,  we  may  not  receive  orphan  product  regulatory  exclusivity  if  the  indication  for  which  we  receive  FDA  or  EMA
regulatory  approval  is  different  than  the  ODD  or  OMPD.  Orphan  exclusivity  may  also  be  lost  for  the  same  reasons  that  ODD  or  OMPD  may  be  lost.
Orphan exclusivity may further be lost if we are unable to assure a sufficient quantity of the product to meet the needs of patients with the rare disease or
condition.

Even if we obtain orphan exclusivity for any of our current or future product candidates, that exclusivity may not effectively protect the product candidate,
if  approved,  from  competition  as  different  products  can  be  approved  for  the  same  condition  or  products  that  are  the  same  as  ours  can  be  approved  for
different conditions. Even after an orphan product is approved, the FDA or EMA can also subsequently approve a product containing the same principal
molecular  features  for  the  same  condition  if  the  regulatory  authority  concludes  that  the  latter  product  is  clinically  superior  by  means  of  greater
effectiveness, greater safety, or providing a major contribution to patient care.

If another sponsor receives approval for such product before we do, we would be prevented from launching our product for the orphan indication during the
period of marketing exclusivity unless we can demonstrate clinical superiority.

We have or may pursue fast track, breakthrough therapy, or RMAT designations from the FDA for one or more of our product candidates. Even if one
or  more  of  our  product  candidates  receives  fast  track,  breakthrough  therapy,  or  RMAT  designations,  we  may  be  unable  to  obtain  and  maintain  the
benefits associated with such designations. These designations may not lead to a faster development or regulatory review or approval process, and will
not increase the likelihood that such product candidates will receive marketing approval.

In May 2022, the FDA granted RMAT designation to NeoCart for the repair of full-thickness lesions of the knee cartilage in adults. In the future, we may
seek additional product designations, such as fast track, breakthrough therapy, or RMAT designation, which are intended to facilitate the development or
regulatory review or approval process for product candidates. Receipt of such a designation is within the discretion of the FDA. Accordingly, even if we
believe  one  of  our  product  candidates  meets  the  criteria  for  a  designation,  the  FDA  may  disagree.  In  any  event,  the  receipt  of  such  a  designation  for  a
product  candidate  may  not  result  in  a  faster  development  process,  review,  or  approval  compared  to  product  candidates  considered  for  approval  under
conventional  FDA  procedures  and  does  not  assure  ultimate  marketing  approval  by  the  FDA.  In  addition,  the  FDA  may  later  decide  that  the  product
candidates no longer meet the designation conditions, in which case any granted designations may be revoked.

The  FDA  may  determine  that  our  product  candidates  have  undesirable  side  effects  that  could  delay  or  prevent  their  regulatory  approval  or
commercialization. If such side effects are identified during the development of our product candidates, we may need to abandon our development of
such product candidates.

55

Table of Contents

Undesirable side effects caused by our product candidates could cause us, IRBs, and other reviewing entities or regulatory authorities to interrupt, delay, 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  comparable  foreign
authorities. For example, if concerns are raised regarding the safety of one of our product candidates as a result of undesirable side effects identified during
preclinical or clinical testing, the FDA may order us to cease further development or issue a letter requesting additional data or information prior to making
a final decision regarding whether or not to approve the product candidate. FDA requests for additional data or information can result in substantial delays
in the approval of a new product candidate.

Undesirable side effects caused by any unexpected characteristics (alone or in combination with other products) for any of our product candidates could
also  result  in  denial  of  regulatory  approval  by  the  FDA  or  other  comparable  foreign  authorities  for  any  or  all  targeted  indications  or  the  inclusion  of
unfavorable  information  in  our  product  labeling,  such  as  limitations  on  the  indicated  uses  or  populations  for  which  the  products  may  be  marketed  or
distributed, a label with significant safety warnings, including boxed warnings, contraindications, and precautions, a label without statements necessary or
desirable for successful commercialization, may result in requirements for costly post-marketing testing and surveillance, or other requirements, including
REMS,  to  monitor  the  safety  or  efficacy  of  the  products.  These  could  prevent  us  from  commercializing  and  generating  revenues  from  the  sale  of  our
product candidates.

Many  compounds  that  initially  showed  promise  in  clinical  or  earlier  stage  testing  have  later  been  found  to  cause  side  effects  that  prevented  further
development of the compound. In addition, adverse events which had initially been considered unrelated to the study treatment may later be found to be
caused  by  the  study  treatment.  Moreover,  incorrect  or  improper  use  of  our  product  candidates  (including  use  more  frequently  than  is  prescribed),  if
approved, by patients could cause unexpected side effects or adverse events. There can be no assurance that our product candidates, if approved, will be
used correctly, and if used incorrectly, such misuse could prevent our receipt or maintenance of marketing approval, resulting in label changes or regulatory
authority safety communications or warnings, or hamper commercial adoption of our product candidate, if approved, at the rate we currently expect.

If any of our product candidates are associated with serious adverse events, undesirable side effects, or have properties that are unexpected, we may need to
abandon  development  or  limit  development  of  that  product  candidate  to  certain  uses  or  subpopulations  in  which  the  undesirable  side  effects  or  other
characteristics are less prevalent, less severe, or more acceptable from a risk-benefit perspective. The therapeutic-related side effects could affect patient
recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. We may also be held liable for harm caused
to  patients  and  our  reputation  may  suffer.  Any  of  these  occurrences  may  significantly  harm  our  business,  financial  condition,  results  of  operations,  and
prospects.

If we experience delays or difficulties in the enrollment of patients in clinical trials, our completion of clinical trials and receipt of necessary regulatory
approvals could be delayed or prevented.

Identifying  and  qualifying  patients  to  participate  in  clinical  trials  of  our  product  candidates  is  critical  to  our  success.  The  timing  of  our  clinical  trials
depends on the speed at which we can recruit patients to participate in testing our product candidates. Our ongoing clinical trials could be discontinued
early if they experience slow enrollment, and we may also experience similar difficulties in future clinical trials. If patients are unwilling to participate in
our clinical trials because of negative publicity from adverse events related to vaccines, gene therapy, or in the industry more broadly, in the clinical trials
for  related  third  party  product  candidates,  or  for  other  reasons,  including  competitive  clinical  trials  for  similar  patient  populations,  the  timeline  for
recruiting  patients,  conducting  studies,  and  obtaining  regulatory  approval  of  potential  products  may  be  delayed.  These  delays  could  result  in  increased
costs,  delays  in  advancing  our  product  development,  delays  in  testing  the  effectiveness  of  our  product  candidates,  or  termination  of  the  clinical  trials
altogether.

We  or  our  clinical  trial  sites  may  not  be  able  to  identify,  recruit,  and  enroll  a  sufficient  number  of  patients,  or  those  with  the  required  or  desired
characteristics in a clinical trial, to complete our clinical trials in a timely manner. Patient enrollment is affected by other factors including:

•

•

•

•

the size and nature of the patient population (for instance, we are pursuing clinical trials for certain orphan indications, for which the size of the
patient population is limited);

the severity of the disease under investigation;

the existence of current treatments for the indications for which we are conducting clinical trials;

the eligibility criteria for and design of the clinical trial in question, including factors such as frequency of required assessments, length of the
study, and ongoing monitoring requirements;

56

•

the  perceived  risks  and  benefits  of  the  product  candidate,  including  the  potential  advantages  or  disadvantages  of  the  product  candidate  being
studied in relation to other available therapies;

competition in recruiting and enrolling patients in clinical trials;

efforts to facilitate timely enrollment in clinical trials;

patient referral practices of physicians;

effectiveness of publicity created by clinical trial sites regarding the trial;

patients’ ability to comply with the specific instructions related to the trial protocol, proper documentation, and use of the product candidate;

an inability to obtain or maintain patients' informed consents;

the risk that enrolled patients will drop out before completion or not return for post-treatment follow-up;

the ability to monitor patients adequately during and after treatment;

the ability to compensate patients for their time and effort; and

the proximity and availability of clinical trial sites for prospective patients.

We may not be able to initiate or continue conducting clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of
eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the United States. Our inability to enroll a
sufficient number of patients for our clinical trials would result in significant delays and could require us to abandon one or more clinical trials altogether.
In particular, there may be low or slow enrollment, and the studies may enroll subjects that do not meet the inclusion criteria, requiring the erroneously
enrolled subjects to be excluded and the trial population to be increased. Moreover, patients in our clinical trials, especially patients in our control groups,
may  be  at  risk  for  dropping  out  of  our  studies  if  they  are  not  experiencing  relief  of  their  disease.  A  significant  number  of  withdrawn  patients  would
compromise the quality of a study's data.

Enrollment difficulties or delays in our clinical trials may result in increased development costs for our product candidates, or the inability to complete
development of our product candidates, which would cause our value to decline, limit our ability to obtain additional financing, and materially impair our
ability to generate revenues.

Data from preclinical studies and early-stage clinical trials may not be predictive of success in later clinical trials.

The results of preclinical studies, preliminary study results, and early-stage clinical trials of our product candidates may not be predictive of the results of
later-stage clinical trials or the ultimately completed clinical trial. Preliminary and final results from such studies may not be representative of study results
that are found in larger, controlled, blinded, and more long-term studies. Product candidates in later stages of clinical trials may fail to show the desired
safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. A number of companies have suffered significant
setbacks in advanced clinical trials, notwithstanding promising results in earlier trials. In some instances, there can be significant variability in safety or
efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes in trial procedures set forth in
protocols, differences in the size and type of the patient populations, changes in and adherence to the clinical trial protocols, and the rate of dropout among
clinical trial participants.

In addition, from time to time, we may publish interim, “top-line,” initial, or preliminary data from our clinical trials. For example, in January 2023 we
announced top-line results from our Phase 2/3 immuno-bridging and broadening study for COVAXIN, which we intend to use together with data from a
safety clinical trial, subject to discussions with the FDA, to support a BLA submission for COVAXIN. Interim data from clinical trials are subject to the
risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data becomes available. Preliminary,
initial,  or  “top-line”  data  also  remain  subject  to  audit  and  verification  procedures  that  may  result  in  the  final  data  being  materially  different  from  the
preliminary data previously published. As a result, interim, “top-line”, initial, and preliminary data should be viewed with caution until the final data are
available. Adverse changes between preliminary, initial, “top-line” or interim data and final data could significantly harm our business prospects.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications
that may be more profitable or for which there is a greater likelihood of success.

Because  we  have  limited  financial  and  managerial  resources,  we  focus  on  research  programs  and  product  candidates  that  we  identify  for  specific
indications. As a result, we may forego or delay pursuit of opportunities with other product candidates or

57

Table of Contents

for other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable
commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for
specific  indications  may  not  yield  any  commercially  viable  products.  If  we  do  not  accurately  evaluate  the  commercial  potential  or  target  market  for  a
particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing, or other royalty arrangements in
cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

We may, in the future, conduct clinical trials for product candidates at sites outside the United States, and the FDA may not accept data from trials
conducted in such locations.

We may, in the future, choose to conduct one or more of our clinical trials outside the United States. Although the FDA may accept data from clinical trials
conducted outside the United States, acceptance of data is in either case subject to the respective conditions imposed by the FDA. For example, the clinical
trial  must  be  well  designed  and  conducted  and  be  performed  by  qualified  investigators  in  accordance  with  ethical  principles,  such  as  IRB  or  ethics
committee approval and informed consent. The trial population must also adequately represent the U.S. population, and the data must be applicable to the
U.S.  population  and  U.S.  medical  practice  in  ways  that  the  FDA  deems  clinically  meaningful.  In  addition,  while  these  clinical  trials  are  subject  to  the
applicable local laws (and therefore failure to comply with such laws could result in regulatory enforcement action), acceptance of the data by the FDA will
be dependent upon its determination that the trials were conducted consistent with all applicable U.S. laws and regulations. If the FDA does not accept the
data  from  any  trial  that  we  conduct  outside  the  United  States,  it  would  likely  result  in  the  need  for  additional  trials,  which  would  be  costly  and  time-
consuming and could delay or permanently halt our development of the applicable product candidates.

Failure to obtain marketing approval in international jurisdictions would prevent our product candidates from being marketed abroad.

In order to market and sell our products in jurisdictions outside the United States, we must obtain separate marketing approvals in international jurisdictions
and comply with numerous and varying regulatory requirements. The approval procedures vary among countries and the time required to obtain approval
may differ substantially from that required to obtain FDA approval. The regulatory approval process outside the United States generally includes all of the
risks  associated  with  obtaining  FDA  approval.  In  addition,  in  many  countries  outside  the  United  States,  it  is  required  that  the  product  be  approved  for
reimbursement before the product can be approved for sale in that country. The clinical trials of our product candidates may not be sufficient to support an
application for marketing approval outside the United States. Seeking foreign regulatory approval could result in difficulties and costs for us and require
additional preclinical studies or clinical trials which could be costly and time consuming.

We do not have any product candidates approved for sale in any jurisdiction, including in international markets, and we do not have experience in obtaining
regulatory approval in international markets. We, or any current or eventual collaborators, may not obtain approvals from regulatory authorities outside the
United States on a timely basis, if at all. Approval by the FDA does not guarantee approval by regulatory authorities in other countries or jurisdictions, and
approval by one regulatory authority outside the United States does not guarantee approval by regulatory authorities in other countries or jurisdictions or by
the FDA. However, the failure to obtain approval in one jurisdiction may compromise our ability to obtain approval elsewhere. We may not be able to file
for marketing approvals and may not receive necessary approvals to commercialize our products in any market.

We  may  be  subject  to  fines,  penalties,  injunctions,  or  other  enforcement  actions  if  we  are  determined  to  be  promoting  the  use  of  our  products,  if
approved, for unapproved or “off-label” uses, resulting in damage to our reputation and business.

We must comply with requirements concerning advertising and promotion for any product candidates for which we obtain marketing approval. Promotional
communications with respect to therapeutics are subject to a variety of legal and regulatory restrictions and continuing review by the FDA, Department of
Justice, Department of Health and Human Services’ Office of Inspector General, state attorneys general, members of Congress, and the public. When the
FDA or comparable foreign regulatory authorities issue regulatory approval for a product candidate, the regulatory approval is limited to those specific uses
and  indications  for  which  a  product  is  approved.  We  may  not  market  or  promote  them  for  other  indications  and  uses,  referred  to  as  off-label  uses.  We
further must be able to sufficiently substantiate any claims that we make for our products, if approved, including claims comparing our products to other
companies’ products and must abide by the FDA’s strict requirements regarding the content of promotion and advertising. While physicians may choose to
prescribe products for uses that are not described in the product’s labeling and for uses that differ from those tested in clinical studies and approved by the
regulatory authorities, we are prohibited from marketing and promoting the products for indications and uses that are not specifically approved by the FDA.

58

Table of Contents

If we are found to have impermissibly promoted any of our product candidates, we may become subject to significant liability and government fines. The
FDA and other agencies actively enforce the laws and regulations regarding product promotion, particularly those prohibiting the promotion of off-label
uses, and a company that is found to have improperly promoted a product may be subject to significant sanctions. The federal government has levied large
civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The
FDA  has  also  requested  that  companies  enter  into  consent  decrees  of  permanent  injunctions  under  which  specified  promotional  conduct  is  changed  or
curtailed.

In the United States, engaging in the impermissible promotion of our products, following approval, for off-label uses can also subject us to false claims and
other  litigation  under  federal  and  state  statutes,  including  fraud  and  abuse  and  consumer  protection  laws.  Such  litigation  can  lead  to  civil  and  criminal
penalties and fines, agreements with governmental authorities that materially restrict the manner in which we promote or distribute therapeutic products
and do business through, for example, corporate integrity agreements, suspension or exclusion from participation in federal and state healthcare programs,
suspension and debarment from government contracts, and refusal of orders under existing government contracts. These false claims statutes include the
federal  civil  FCA,  which  allows  any  individual  to  bring  a  lawsuit  against  a  company  on  behalf  of  the  federal  government  ("qui  tam"  action)  alleging
submission of false or fraudulent claims, or causing others to present such false or fraudulent claims, for payment by a federal program such as Medicare or
Medicaid. If the government decides to intervene and prevails in the lawsuit, the individual will share in the proceeds from any fines or settlement funds. If
the government declines to intervene, the individual may pursue the case alone. These FCA lawsuits against sponsors of drugs and biologics have increased
significantly in volume and breadth, leading to several substantial civil and criminal settlements, up to $3.0 billion, pertaining to certain sales practices and
promoting off-label uses. In addition, FCA lawsuits may expose sponsors to follow-on claims by private payors based on fraudulent marketing practices.
This growth in litigation has increased the risk that companies will have to defend a false claim action, and pay settlements fines or restitution, as well as
criminal and civil penalties, agree to comply with burdensome reporting and compliance obligations, and be excluded from Medicare, Medicaid, or other
federal and state healthcare programs. If we do not lawfully promote our approved products, if any, we may become subject to such litigation and, if we do
not successfully defend against such actions, those actions may have a material adverse effect on our business, financial condition, results of operations,
and prospects.

In the United States, the distribution of product samples to physicians must further comply with the requirements of the U.S. PDMA, and the promotion of
biologic and pharmaceutical products are subject to additional FDA requirements and restrictions on promotional statements. If the FDA determines that
our promotional activities violate our regulations and policies pertaining to product promotion, it could request that we modify our promotional materials or
subject us to regulatory or other enforcement actions, including issuance of warning letters or untitled letters, suspension or withdrawal of an approved
product from the market, requests for recalls, payment of civil fines, disgorgement of money, imposition of operating restrictions, injunctions or criminal
prosecution, and other enforcement actions. These regulatory and enforcement actions could significantly harm our business, financial condition, results of
operations, and prospects.

Even  if  our  product  candidates  receive  regulatory  approval,  we  will  be  subject  to  ongoing  obligations  and  continued  regulatory  review,  which  may
result in significant additional expense.

Any product candidate for which we obtain marketing approval will be subject to extensive and ongoing requirements of and review by the FDA and other
regulatory authorities, including requirements related to the manufacturing processes, post-approval clinical data, labeling, packaging, distribution, adverse
event  reporting,  storage,  recordkeeping,  export,  import,  advertising,  marketing,  and  promotional  activities  for  such  product.  These  requirements  further
include submissions of safety and other post-marketing information, including manufacturing deviations and reports, registration and listing requirements,
the  payment  of  annual  fees,  continued  compliance  with  current  GMP  requirements  relating  to  manufacturing,  quality  control,  quality  assurance,  and
corresponding maintenance of records and documents, requirements regarding the distribution of samples to physicians and GCPs, for any clinical trials
that we conduct post-approval.

Even if marketing approval of a product candidate is granted, the approval may be subject to limitations on the indicated uses and populations for which the
product  may  be  marketed  or  to  the  conditions  of  approval,  including  significant  safety  warnings,  such  as  boxed  warnings,  contraindications,  and
precautions  that  are  not  desirable  for  successful  commercialization.  Any  approved  products  may  also  be  subject  to  a  REMS  that  render  the  approved
product not commercially viable or other post-market requirements, such as Phase 4 studies, or restrictions. If the FDA or comparable foreign regulatory
authorities become aware of new safety information after the approval of any of our product candidates, they may, among other actions, withdraw approval,
require  labeling  changes  or  establishment  of  a  REMS  or  similar  strategy,  impose  significant  restrictions  on  a  product’s  indicated  uses  or  marketing,  or
impose ongoing requirements for potentially costly post-approval studies or post-market surveillance.

59

Table of Contents

We and any of our collaborators, including our contract manufacturers, could be subject to periodic unannounced inspections by the FDA to monitor and
ensure  compliance  with  current  GMP  and  other  FDA  regulatory  requirements.  Application  holders  must  further  notify  the  FDA,  and  depending  on  the
nature of the change, obtain FDA pre-approval for product and manufacturing changes.

In addition, later discovery of previously unknown adverse events or that the product is less effective than previously thought or other problems with our
products, manufacturers, or manufacturing processes, or failure to comply with regulatory requirements both before and after approval, may yield various
results, including:

•

•

restrictions on manufacturing, distribution, or marketing of such products;

restrictions on the labeling, including restrictions on the indication or approved patient population, and required additional warnings, such as black
box warnings, contraindications, and precautions;

• modifications to promotional pieces;

•

•

•

•

•

•

issuance of corrective information;

requirements to conduct post-marketing studies or other clinical trials;

clinical holds or termination of clinical trials;

requirements to establish or modify a REMS, or a comparable foreign authority may require that we establish or modify a similar strategy;

liability for harm caused to patients or subjects;

reputational harm;

• warning, untitled, Form 483s, or cyber letters;

•

•

•

•

•

•

•

•

•

suspension of marketing or withdrawal or recall of the products from the market;

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

refusal to approve pending applications or supplements to approved applications that we submit;

fines, restitution, or disgorgement of profits or revenues;

suspension or withdrawal of marketing approvals;

refusal to permit the import or export of our products;

product seizure or detention;

FDA debarment, suspension and debarment from government contracts, and refusal of orders under existing government contracts, exclusion from
federal healthcare programs, consent decrees, or corporate integrity agreements; or

injunctions or the imposition of civil or criminal penalties, including imprisonment.

Any  of  these  events  could  prevent  us  from  achieving  or  maintaining  market  acceptance  of  the  particular  product  candidate,  if  approved,  or  could
substantially increase the costs and expenses of developing and commercializing such product, which in turn could delay or prevent us from generating
significant  revenues  from  its  sale.  Any  of  these  events  could  further  have  other  material  and  adverse  effects  on  our  operations  and  business  and  could
adversely impact our stock price and could significantly harm our business, financial condition, results of operations, and prospects.

The  FDA’s  policies  may  change,  and  additional  government  regulations  may  be  enacted  that  could  prevent,  limit,  or  delay  regulatory  approval  of  our
product candidates, limit the marketability of our product candidates, or impose additional regulatory obligations on us. Changes in medical practice and
standard of care may also impact the marketability of our product candidates, if approved.

We will need to obtain FDA approval of any proposed product names, and any failure or delay associated with such approval may adversely affect our
business.

Any  name  we  intend  to  use  for  our  product  candidates  will  require  approval  from  the  FDA  regardless  of  whether  we  have  secured  a  formal  trademark
registration from the USPTO. The FDA typically conducts a review of proposed product names, including an evaluation of the potential for confusion with
other product names. The FDA may also object to a product name if

60

Table of Contents

it  believes  the  name  inappropriately  implies  medical  claims  or  contributes  to  an  overstatement  of  efficacy.  If  the  FDA  objects  to  any  of  our  proposed
product names, we may be required to adopt alternative names for our product candidates. If we adopt alternative names, we would lose the benefit of any
existing trademark applications for such product candidate and may be required to expend significant additional resources in an effort to identify a suitable
product name that would qualify under applicable trademark laws, not infringe upon the existing rights of third-parties, and be acceptable to the FDA. We
may be unable to build a successful brand identity for a new trademark in a timely manner or at all, which would limit our ability to commercialize our
product candidates, if approved.

Risks Related to the Commercialization of Our Product Candidates

We  have  no  prior  experience  in  the  marketing,  sale,  and  distribution  of  biotechnology  products  and  there  can  be  no  assurance  that  our  product
candidates, if approved, will be successfully commercialized.

We have no prior experience in the marketing, sale, and distribution of biotechnology products, and there are significant risks involved in the building and
managing  of  a  commercial  infrastructure.  The  establishment  and  development  of  commercial  capabilities,  including  compliance  plans,  to  market  any
products we may develop will be expensive and time consuming and could delay any product launch, and we may not be able to successfully develop this
capability. We will have to compete with other pharmaceutical or biotechnology companies to recruit, hire, train, manage, and retain marketing and sales
personnel. Factors that may inhibit our efforts to commercialize our product candidates include:

•

•

•

•

•

•

•

•

•

•

•

•

the inability to recruit, train, manage, and retain adequate numbers of effective sales and marketing personnel;

the inability of sales personnel to obtain access to physicians or persuade adequate numbers of physicians to prescribe our product candidates;

our inability to effectively oversee a geographically dispersed sales and marketing team;

the costs associated with training sales and marketing personnel on legal and regulatory compliance matters and monitoring their actions;

an inability to secure adequate coverage and reimbursement by government and private health plans;

reduced  realization  on  government  sales  from  mandatory  discounts,  rebates  and  fees,  and  from  price  concessions  to  private  health  plans  and
pharmacy benefit managers necessitated by competition for access to managed formularies;

the clinical indications for which the products are approved and the claims that we may make for the products;

limitations or warnings, including distribution or use restrictions, contained in the products' approved labeling;

any distribution and use restrictions imposed by the FDA or other foreign regulatory agencies, including those that we may agree to as part of a
mandatory REMS or voluntary risk management plan;

liability for sales or marketing personnel who fail to comply with the applicable legal and regulatory requirements;

the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with
more extensive product lines; and

unforeseen costs and expenses associated with creating an independent sales and marketing organization or engaging a contract sales organization.

Should any of the foregoing occur, we may not be successful in commercializing any product candidates for which we receive marketing approval.

If we obtain approval to commercialize our product candidates outside of the United States, a variety of risks associated with international operations
could materially adversely affect our business.

COVAXIN has received EUA in Mexico in adults ages 18 years and older. If any of our product candidates are approved for commercialization, we may
enter into agreements with third parties to market them on a worldwide basis or in more limited geographical regions. We expect that we will be subject to
additional  risks  related  to  conducting  marketing  and  sales  activities  in  international  jurisdictions  and  entering  into  international  business  relationships,
including:

•

•

different regulatory requirements for approval of drugs and biologics in foreign countries;

the  potential  for  so-called  parallel  importing,  which  is  what  happens  when  a  local  seller,  faced  with  high  or  higher  local  prices,  opts  to  import
goods from a foreign market (with low or lower prices) rather than buying them locally;

61

Table of Contents

•

•

•

•

•

•

•

challenges  enforcing  our  contractual  and  intellectual  property  rights,  especially  in  those  foreign  countries  that  do  not  respect  and  protect
intellectual property rights to the same extent as the United States;

the need to seek additional patent approvals, licenses to patents held by third parties, and/or face claims of infringing third-party patent rights;

unexpected changes in tariffs, trade barriers, and regulatory requirements;

economic weakness, including inflation or political instability in particular foreign economies and markets;

compliance with tax, employment, immigration, and labor laws for employees living or traveling abroad;

foreign currency fluctuations, which could result in increased operating expenses and reduced revenues, and other obligations incident to doing
business in another country;

difficulties staffing and managing foreign operations;

• workforce uncertainty in countries where labor unrest is more common than in the United States;

•

•

•

potential liability under the FCPA, the U.K. Bribery Act 2010 (the "Bribery Act"), or other comparable foreign regulations;

production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and

business interruptions resulting from geopolitical actions, including war and terrorism, or natural disasters including pandemics or other outbreaks
of infectious disease, earthquakes, typhoons, floods, and fires.

These and other risks associated with international operations may materially adversely affect our ability to attain or maintain profitable operations.

If  we  are  unable  to  establish  effective  marketing  and  sales  capabilities  or  enter  into  agreements  with  third  parties  to  market  and  sell  our  product
candidates, if approved, we may be unable to generate product revenues.

We  currently  do  not  have  a  commercial  infrastructure  for  the  marketing,  sale,  and  distribution  of  biotechnology  products.  If  approved,  in  order  to
commercialize  our  products,  we  must  build  our  marketing,  sales,  and  distribution  capabilities  or  make  arrangements  with  third  parties  to  perform  these
services. If we do not establish sales, marketing, and distribution capabilities successfully, either on our own or in collaboration with third parties, we will
not be successful in commercializing any product candidates for which we receive marketing approval.

Subject  to  regulatory  approval  of  any  of  our  product  candidates,  we  may  build  a  commercial  team  of  specialty  sales  and  marketing  representatives  in
support of our product candidates that we develop in the United States or other foreign countries, if approved, as well as distribution capabilities. There are
risks  involved  with  us  establishing  our  own  sales,  marketing,  and  distribution  capabilities.  Recruiting  and  training  a  sales  force  is  expensive  and  time-
consuming, particularly to the extent that we seek to commercialize any product, if approved, for an indication, such as dry AMD, that has a large patient
population. We will be competing with many companies that currently have extensive and well-funded marketing and sales operations to recruit, hire, train,
and retain marketing and sales personnel. Further, we may underestimate the size of the sales force required for a successful product launch and may need
to expand our sales force earlier and at a higher cost than we anticipate. If the commercial launch of our product candidates, if approved, 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.

We may also or alternatively decide to collaborate with a third-party or contract sales organization to commercialize any approved product candidates, in
which  event,  our  ability  to  generate  product  revenues  may  be  limited.  Our  product  revenues  and  our  profitability,  if  any,  under  any  third-party
collaboration, distribution, or other marketing arrangements are likely to be lower than if we were to market, sell, and distribute the applicable product
candidate,  if  approved,  entirely  ourselves.  We  may  not  be  successful  in  entering  into  arrangements  with  third  parties  to  sell,  market,  and  distribute  our
product candidates, if approved, or may be unable to do so on terms that are favorable to us. In addition, we would have less control over the sales efforts
of any other third parties involved in our commercialization efforts and any of them may fail to devote the necessary resources and attention to sell and
market  our  product  candidates,  if  approved,  effectively.  We  could  also  be  held  liable  if  such  third  parties  failed  to  comply  with  applicable  legal  or
regulatory requirements.

In the event we are unable to develop a team of marketing and sales representatives or to establish an effective third-party contractual relationship for such
services, we may not be able to commercialize our product candidates, if approved, which

62

Table of Contents

would limit our ability to generate product revenues. Even if we are able to effectively hire a sales force and develop a marketing and sales infrastructure,
our sales force and marketing teams may not be successful in commercializing our product candidates, if approved.

We  face  significant  competition  from  other  pharmaceutical  and  biotechnology  companies,  academic  institutions,  government  agencies,  and  other
research organizations. Our operating results will suffer if we fail to compete effectively.

The biotechnology industry is characterized by rapidly advancing technologies as well as a strong emphasis on intellectual property leading to a highly
competitive environment for the development and commercialization of therapeutic products, regenerative medicines, and vaccines. We face competition
with  respect  to  our  current  product  candidates  and  will  face  competition  with  respect  to  any  product  candidates  that  we  may  seek  to  develop  or
commercialize in the future. We face competition from many different sources, including from major pharmaceutical companies, specialty pharmaceutical
companies,  biotechnology  companies,  academic  institutions,  government  agencies,  and  other  public  and  private  research  organizations  that  conduct
research, seek patent protection, and establish collaborative arrangements for research, development, manufacturing, and commercialization.

The development and commercialization of gene therapies is highly competitive. We are aware of several companies focusing on gene therapies for various
ophthalmic indications including Applied Genetic Technologies Corporation, as acquired by Syncona Limited, Astellas Pharma Inc., MeiraGTx Holdings
plc in partnership with Janssen Pharmaceuticals, Inc., Nanoscope Therapeutics Inc., REGENXBIO Inc., Novartis AG, F. Hoffmann-La Roche AG ("Roche
AG"),  Kiora  Pharmaceuticals,  Inc.,  Genentech,  Inc.  in  partnership  with  Lineage  Cell  Therapeutics,  Inc.,  and  Luxturna,  the  product  developed  by  Spark
Therapeutics,  Inc.  and  marketed  by  Roche  AG,  is  currently  the  only  gene  therapy  approved  to  treat  IRDs  in  the  United  States  which  addresses  only
mutations in the RPE65 gene. The mutation associated with the RPE65 gene represents just one of more than 125 mutated genes linked to RP and LCA.

The regenerative medicine sector is characterized by innovative science, rapidly advancing technologies, and a strong emphasis on proprietary products.
The  competitive  landscape  in  the  field  of  articular  cartilage  repair  in  the  U.S.  is  emerging  and  has  stimulated  a  substantial  amount  of  interest  from
companies developing tissue repair solutions. Companies that may compete with our NeoCart product candidate include Vericel Corporation's MACI, the
only FDA-approved ACI product in the United States, and Aesculap Biologics, LLC's NOVOCART 3D, which is currently enrolling subjects in their Phase
3 clinical trial.

We  face,  and  will  continue  to  face,  intense  competition  from  companies  as  well  as  institutions  that  are  pursuing  or  have  commercialized  vaccines  that
would compete with our vaccine candidates, COVAXIN and our novel inhaled mucosal vaccine platform, if commercialized. The competitive landscape of
COVID-19 vaccines has been rapidly developing since the beginning of the COVID-19 pandemic and includes competitors such as Pfizer Inc./BioNTech
SE, Moderna, Inc., AstraZeneca PLC, Novavax, Inc., Sinovac Biotech Ltd., Gamaleya Research Institute of Epidemiology and Microbiology, and Center
for  Genetic  Engineering  and  Biotechnology.  Each  of  the  aforementioned  vaccines  have  been  authorized  or  approved  in  at  least  one  country  within  the
Ocugen  COVAXIN  Territory  or  the  Mucosal  Vaccine  Territory  and  are  intramuscular  vaccines.  CanSinoBIO's  Convidecia  Air,  an  intranasal  vaccine
targeting  COVID-19,  has  been  approved  in  China.  Other  competitors  for  our  novel  inhaled  mucosal  vaccine  platform  include  CyanVac  LLC,  Meissa
Vaccines, Inc., Codagenix, Inc., Intravacc B.V., McMaster University, and Tetherex Pharmaceuticals Corporation. Companies such as Pfizer Inc./BioNTech
SE,  Moderna,  Inc.,  CureVac  N.V  in  partnership  with  GSK  plc,  Vivaldi  Biosciences  Inc.,  and  Novavax,  Inc.  are  also  in  the  process  of  developing  a
combination vaccine that will protect against COVID-19 and the seasonal flu. Vivaldi Biosciences Inc. is also currently undergoing clinical trials for their
intranasal vaccine for the seasonal flu.

The  development  and  commercialization  of  biologic  products  is  highly  competitive  as  well.  Companies  that  may  compete  with  our  OCU200  product
candidate include Roche AG, Regeneron Pharmaceuticals, Inc., AsclepiX Therapeutics, Inc., Outlook Therapeutics, Inc., Novartis AG, Oxurion NV, Unity
Biotechnology, Inc., Opthea Limited, and 4D Molecular Therapeutics, Inc. Roche AG, Regeneron Pharmaceuticals, Inc., and Novartis AG have marketed
anti-VEGF products.

Our commercial opportunities could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have
fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop and for which we receive approval. Our
competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for our product candidates,
which could result in our competitors establishing a strong market position before we are able to enter the market. They may obtain patent protection or
other  intellectual  property  rights  that  allow  them  to  develop  and  commercialize  their  products  before  us  and  could  limit  our  ability  to  develop  or
commercialize our product candidates.

63

Table of Contents

In addition, our ability to compete may be affected in many cases by insurers or other third-party payors' coverage decisions, particularly Medicare, seeking
to encourage the use of generic or biosimilar products. Many of the products that will compete with our product candidates, if approved, are available on a
generic basis, and our product candidates may not demonstrate sufficient additional clinical benefits to clinicians, patients, or payors to justify a higher
price compared to generic products. Additional competing products are expected to become available on a generic basis over the coming years.

Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and
expertise  in  research  and  development,  manufacturing,  preclinical  testing,  conducting  clinical  trials,  obtaining  regulatory  approvals,  and  marketing
approved  products  than  we  do.  Mergers  and  acquisitions  in  the  pharmaceutical  and  biotechnology  industries  may  result  in  even  more  resources  being
concentrated  among  a  smaller  number  of  our  competitors.  Early-stage  companies  may  also  prove  to  be  significant  competitors,  particularly  through
collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and
management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to,
or necessary for, our programs.

If our product candidates for which we receive approval do not achieve broad market acceptance, the revenues that we generate from their sales will be
limited.

Even  if  our  product  candidates  are  approved  by  the  appropriate  regulatory  authorities  for  marketing  and  sale,  they  may  not  gain  acceptance  among
physicians, patients, third-party payors, and others in the medical community. Physicians are often reluctant to switch their patients and patients may be
reluctant  to  switch  from  existing  therapies  even  when  new  and  potentially  more  effective  or  safer  treatments  enter  the  market.  We  have  never
commercialized a product candidate for any indication, and efforts to educate the medical community and third-party payors on the benefits of our product
candidates may require significant resources and may not be successful. With respect to our product candidates being developed based on our modifier
gene therapy platform, market acceptance may also be constrained by ethical, social, and legal concerns about gene therapy and genetic research, which
could result in additional regulations restricting or prohibiting the products and processes we may use. The novelty of the technology and any negative
publicity  surrounding  adverse  events  associated  with  gene  therapy  may  also  prevent  the  medical  community,  patients,  and  third-party  payors  from
accepting gene therapy products in general, and our product candidates in particular, as medically useful, cost-effective, and safe.

Market  acceptance  of  our  product  candidates  by  the  medical  community,  patients,  and  third-party  payors  will  depend  on  a  number  of  factors,  some  of
which are beyond our control. If any product candidates for which we obtain regulatory approval does not gain an adequate level of market acceptance, it
may not generate significant product revenues or become profitable.

The degree of market acceptance of any of our product candidates will depend on a number of factors, including:

•

•

•

•

•

•

•

•

•

•

•

the efficacy of our product candidates;

the prevalence and severity of adverse events associated with such product candidates;

the clinical indications for which the product candidates are approved and the approved claims that we may make for the products;

limitations or warnings contained in the product's FDA-approved labeling, including potential limitations or warnings for such product candidates
that may be more restrictive than other competitive products;

changes in the standard of care for the targeted indications for such product candidates, which could reduce the marketing impact of any claims
that we could make following FDA approval, if obtained;

the relative convenience and ease of administration of such product candidates;

cost of treatment versus economic and clinical benefit in relation to alternative treatments or therapies;

the availability of third-party formulary coverage and adequate coverage or reimbursement by third parties, such as insurance companies and other
healthcare payors, and by government healthcare programs, including Medicaid and particularly by Medicare in light of the prevalence of retinal
diseases in persons over age 55;

the price concessions required by third party payors to obtain coverage;

the extent and strength of our manufacturing, marketing, and distribution of such product candidates;

distribution and use restrictions imposed by the FDA with respect to such product candidates or to which we agree as part of a REMS or voluntary
risk management plan;

64

Table of Contents

•

•

•

the extent of availability of generic or biosimilar versions of any products that compete with any of our product candidates and the extent to which
they are offered at a substantially lower price than we expect to offer for our product candidates, if approved;

adverse publicity about the product or favorable publicity about competitive products; and

potential product liability claims.

If the market opportunities for our product candidates are smaller than we believe, our revenue may be adversely affected and our business may suffer.

The  potential  market  opportunities  for  our  product  candidates  are  difficult  to  precisely  estimate.  Our  estimates  of  the  potential  market  opportunities  are
predicated on many assumptions, which may include industry knowledge and publications, third-party research reports, and other surveys, some of which
we may have commissioned. Industry publications and third-party research, surveys and studies generally indicate that their information has been obtained
from sources believed to be reliable, although they do not guarantee the accuracy or completeness of such information. While we believe these industry
publications and third-party research, surveys, and studies are reliable, we have not independently verified such data. In addition, while we believe that our
internal  assumptions  are  reasonable,  these  assumptions  involve  the  exercise  of  significant  judgment  on  the  part  of  our  management,  are  inherently
uncertain, and the reasonableness of these assumptions has not been assessed by an independent source. If any assumptions prove to be inaccurate, the
actual markets for our product candidates could be smaller than our estimates of the potential market opportunities, and as a result, our product revenue
may be limited, and it may be more difficult for us to achieve or maintain profitability.

If third-party payors do not reimburse patients for our products candidates, if approved, or if reimbursement levels are set too low for us to sell our
product  candidates  at  a  profit,  our  ability  to  successfully  commercialize  our  product  candidates,  if  approved,  and  our  results  of  operations  will  be
harmed.

Our  ability  to  successfully  commercialize  our  product  candidates,  if  approved,  will  depend  in  part  on  the  extent  to  which  coverage  and  adequate
reimbursement for our product candidates will be available in a timely manner from third-party payors, including governmental healthcare programs such
as  Medicare  and  Medicaid,  commercial  health  insurers,  and  managed  care  organizations.  This  is  particularly  true  with  respect  to  OCU200,  our  novel
biologic product candidate, in the case of wet AMD, which is most prevalent in persons over age 55. Government authorities and other third-party payors,
such  as  private  health  insurers  and  health  maintenance  organizations,  determine  which  medications  they  will  cover  and  establish  reimbursement  levels.
Reimbursement decisions by particular third-party payors depend upon a number of factors, including each third-party payor's determination that use of a
product is:

•

•

•

•

a covered benefit under its health plan;

appropriate and medically necessary for the specific condition or disease;

cost effective; and

neither experimental nor investigational.

Obtaining  coverage  and  reimbursement  approval  for  our  product  candidates  from  government  authorities  or  other  third-party  payors  may  be  a  time
consuming  and  costly  process  that  could  require  us  to  provide  supporting  scientific,  clinical,  and  cost-effectiveness  data,  including  expensive
pharmacoeconomic studies beyond the data required to obtain marketing approval, for the use of each product candidate to each government authority or
other third-party payor. We may not be able to provide data sufficient to gain acceptance with respect to coverage and reimbursement.

Third-party payors may deny reimbursement for covered products if they determine that a medical product was not used in accordance with cost-effective
diagnosis methods, as determined by the third-party payor, or was used for an unapproved indication. Third-party payors also may refuse to reimburse for
procedures  and  devices  deemed  to  be  experimental.  Third-party  payors  may  also  limit  coverage  to  specific  products  on  an  approved  list,  or  formulary,
which might not include all of the approved products for a particular indication.

Increasingly, third-party payors are also requiring that drug companies provide them with predetermined discounts from list prices and are challenging the
prices charged for medical products. These third-party payors could also impose price controls and other conditions that must be met by patients prior to
providing coverage for use of our product candidates, if approved. For example, insurers may establish a "step-edit" system that requires a patient to first
use a lower price alternative product prior to becoming eligible for reimbursement of a higher price product.

65

Table of Contents

Third-party payors are increasingly attempting to contain healthcare costs by limiting both coverage and the level of reimbursement for medical products
and services. The process for determining whether a payor will provide coverage for a product may be separate from the process of setting the price or
reimbursement  rate  that  the  payor  will  pay  for  the  product  once  coverage  is  approved.  Levels  of  reimbursement  may  also  decrease  in  the  future,  and
legislation, regulation, or reimbursement policies of third-party payors may adversely affect the demand for and reimbursement available for our product
candidates,  which  in  turn,  could  negatively  impact  pricing.  If  patients  are  not  adequately  reimbursed  for  our  product  candidates,  if  approved,  they  may
reduce or discontinue purchases of it, which would result in a significant shortfall in achieving revenue expectations and negatively impact our business,
prospects,  and  financial  condition.  The  IRA  contains  substantial  drug  pricing  reforms,  including  the  establishment  of  a  drug  price  negotiation  program
within  the  U.S.  Department  of  Health  and  Human  Services  that  would  require  manufacturers  to  charge  a  negotiated  "maximum  fair  price"  for  certain
selected drugs or pay an excise tax for noncompliance, the establishment of rebate payment requirements on manufacturers of certain drugs payable under
Medicare Parts B and D to penalize price increases that outpace inflation, and requires manufacturers to provide discounts on Part D drugs. Substantial
penalties can be assessed for noncompliance with the drug pricing provisions in the IRA. The IRA could have the effect of reducing the prices we can
charge  and  reimbursement  we  receive  for  our  products,  if  approved,  thereby  reducing  our  profitability,  and  could  have  a  material  adverse  effect  on  our
financial  condition,  results  of  operations,  and  growth  prospects.  The  effect  of  IRA  on  our  business  and  the  biotechnology  industry  in  general  is  not  yet
known.

Risks Related to Our Dependence on Third Parties

We rely, and expect to continue to rely, on third parties to conduct, supervise, and monitor our preclinical studies and clinical trials we may initiate, and
those  third  parties  may  not  perform  satisfactorily,  including  failing  to  meet  deadlines  for  the  completion  of  such  trials  or  failing  to  comply  with
regulatory requirements.

We rely on third parties, study sites, and others to conduct, supervise, and monitor our preclinical and clinical trials for our product candidates. We expect
to continue to rely on third parties, such as CDMOs, clinical data management organizations, medical and scientific institutions, and clinical and preclinical
investigators to conduct our preclinical studies and clinical trials.

While we have, or expect to have, agreements governing the activities of such third parties, we will have limited influence and control over their actual
performance and activities. Third-party service providers are not our employees, and except for remedies available to us under agreements with such third
parties,  we  cannot  control  whether  or  not  they  devote  sufficient  time  and  resources  to  our  preclinical  studies  or  clinical  trials.  Nevertheless,  we  will  be
responsible for ensuring that each of our preclinical studies and clinical trials is conducted in accordance with the applicable protocol and legal, regulatory,
and scientific standards, and our reliance on third parties will not relieve us of our regulatory responsibilities. For example, we will remain responsible for
ensuring that each of our trials is conducted in accordance with the general investigational plan and protocols for the trial. We must also ensure that our
preclinical trials are conducted in accordance with GLP and under current GMP conditions, as appropriate. Moreover, the FDA and comparable foreign
regulatory authorities require us to comply with GCPs for conducting, recording, and reporting the results of clinical trials to assure that data and reported
results are credible and accurate and that the rights, integrity, and confidentiality of trial participants are protected. The FDA enforces these GCPs through
periodic inspections of trial sponsors, principal investigators, clinical trial sites, and IRBs.

If these third parties upon which we depend do not successfully carry out their contractual duties, meet expected deadlines, conduct our preclinical studies
or any clinical trials in accordance with regulatory requirements or our stated protocols, if they need to be replaced or if the quality or accuracy of the data
they obtain is compromised due to the failure to adhere to our protocols, regulatory requirements, or for other reasons:

• we, our CDMOs, or other third-party collaborators may be subject to regulatory enforcement or other legal actions;

•

the data generated in our preclinical studies or clinical trials may be deemed unreliable and our such studies and clinical trials may need to be
repeated, extended, delayed, or terminated;

• we may not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates; or

• we may not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates, if approved.

We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our preclinical studies or
clinical trials will comply with the applicable regulatory requirements. To the extent we are unable to successfully identify and manage the performance of
third-party service providers in the future, our business may be materially and adversely affected. As a result, our results of operations and the commercial
prospects for our product candidates would be harmed, our costs could increase, and our ability to generate revenues could be delayed.

66

Table of Contents

Our anticipated reliance on third parties for clinical trials will entail additional risks. Our third-party service providers may have relationships with other
entities, some of which may be our competitors, for whom they may also be conducting clinical trials or other therapeutic development activities that could
harm  our  competitive  position.  In  addition,  we  will  be  required  to  report  certain  financial  interests  of  our  third-party  investigators  if  these  relationships
exceed certain financial thresholds or meet other criteria. The FDA or comparable foreign regulatory authorities may question the integrity of the data from
those  clinical  trials  conducted  by  investigators  who  may  have  conflicts  of  interest.  Lastly,  we  are  required  to  register  certain  clinical  trials  and  post  the
results of certain completed clinical trials on a government-sponsored database, clinicaltrials.gov, within specified timeframes. Failure to do so can result
in enforcement actions and adverse publicity.

Agreements with third parties conducting or otherwise assisting with our clinical or preclinical studies might terminate for a variety of reasons, including a
failure to perform by the third parties. If any of our relationships with these third parties terminate, we may not be able to enter into arrangements with
alternative  providers  or  do  so  on  commercially  reasonable  terms.  Switching  or  adding  additional  third  parties  involves  additional  cost  and  requires
management time and focus. In addition, there is a natural transition period when a new third party commences work. As a result, if we need to enter into
alternative arrangements, it could delay our product development activities and adversely affect our business. Though we intend to carefully manage our
relationships with third parties, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will
not have a material adverse impact on our business, financial condition, prospects, and results of operations.

We  will  also  rely  on  other  third  parties  to  store  and  distribute  our  product  candidates  for  preclinical  purposes  or  clinical  trials  that  we  conduct.  Any
performance  failure  on  the  part  of  our  distributors  could  delay  development,  marketing  approval,  or  commercialization  of  our  product  candidates,  if
approved, producing additional losses and depriving us of potential product revenue.

If  we  encounter  difficulties  in  negotiating  commercial  manufacturing  and  supply  agreements  with  third-party  manufacturers  and  suppliers  of  our
product candidates or any product components, our ability to commercialize our product candidates, if approved, would be impaired.

We  have  entered  into  a  strategic  partnership  with  CanSinoBIO  to  manufacture  our  modifier  gene  therapy  pipeline  product  candidates.  Under  this
agreement,  CanSinoBIO  is  responsible  for  the  CMC  development  and  manufacture  of  clinical  supplies  for  OCU400,  OCU410  and  OCU410ST.  The
agreement also provides commercialization rights to CanSinoBIO in Greater China. This agreement may be adversely affected if the U.S. government were
to impose restrictions related to goods manufactured in or imported from China.

We  do  not  currently  have  the  internal  capacity  to  manufacture  COVAXIN,  if  approved.  Accordingly,  we  are  dependent  upon  third  parties  for  the
manufacture of COVAXIN for clinical trials and commercial supply, if approved. Bharat Biotech agreed to provide us with preclinical and clinical data, and
to transfer to us certain proprietary technology owned or controlled by Bharat Biotech, that is necessary for the successful commercial manufacture and
supply of COVAXIN to support its commercial sale in the Ocugen Covaxin Territory, if approved. Until the completion of the technology transfer and until
we  are  capable  and  primarily  responsible  for  the  manufacture  and  supply  of  COVAXIN  in  the  Ocugen  Covaxin  Territory  through  the  third-party
manufacturer we have selected, Bharat Biotech has the exclusive right to manufacture COVAXIN and we will be wholly dependent on Bharat Biotech for
the manufacture and supply of clinical testing materials required for our development activities and all of our requirements of commercial quantities of
COVAXIN,  if  approved.  We  and  Bharat  Biotech  have  entered  into  a  separate  Supply  Agreement  setting  forth  the  terms  of  such  supply  arrangements.
Although the Supply Agreement is in effect, there can be no assurance that Bharat Biotech will in fact provide such doses, whether due to shortages in
supply, diversion of vaccine resources to other uses deemed more immediate, or other factors, including Bharat Biotech's ability to successfully respond to
the deficiencies identified in an inspection conducted by the WHO.

We have selected Jubilant HollisterStier of Spokane, Washington, as our manufacturing partner for COVAXIN, if approved, to prepare for the potential
commercial manufacturing of COVAXIN. There can be no assurance that we will be successful in transitioning the manufacture of COVAXIN from Bharat
Biotech  to  Jubilant  HollisterStier  or  any  other  third-party  manufacturer.  A  technology  transfer  of  a  manufacturing  process  can  be  time-consuming  and
expensive and there can be no assurance that such transfer will be successful or that Jubilant HollisterStier will be able to manufacture our drug products
successfully,  if  approved.  Certain  manufacturing  processes  for  COVAXIN  are  novel  and  complex.  Due  to  the  nature  of  this  vaccine  candidate,  we  may
encounter difficulties in manufacturing, product release, shelf life, testing, storage and supply chain management, or shipping. These difficulties could be
due to any number of reasons including, but not limited to, complexities of producing batches at a larger scale, equipment failure, choice, availability, and
quality of raw materials, analytical testing technology, and product instability. Insufficient stability or shelf life of COVAXIN could materially delay our
ability to continue any potential commercialization activities due to the need to manufacture additional commercial supply of

67

Table of Contents

COVAXIN,  if  approved.  Moreover,  notwithstanding  our  selection  of  Jubilant  HollisterStier  as  our  commercial  manufacturing  partner,  we  expect  to
continue to be dependent on Bharat Biotech as a single-source supplier for the supply of certain raw materials necessary for the manufacture of COVAXIN,
including the adjuvant and active pharmaceutical ingredient. If, for any reason, Bharat Biotech is unable to provide an adequate supply of these materials
(including  Bharat  Biotech's  ability  to  successfully  respond  to  the  deficiencies  identified  in  an  inspection  conducted  by  the  WHO),  our  ability  to  timely
complete the technology transfer to Jubilant HollisterStier and to obtain adequate quantities of commercial supply of COVAXIN, if authorized or approved,
could be jeopardized.

Engaging  Jubilant  HollisterStier  as  our  commercial  manufacturing  partner  may  also  require  additional  testing,  notification,  or  approval  by  the  FDA  or
another comparable foreign regulatory authorities. If Jubilant HollisterStier proceeds to scale up its manufacturing of COVAXIN for commercialization, if
approved, we may encounter unexpected issues relating to the manufacturing process or the quality, purity, and stability of the product candidate, and we
may be required to refine or alter our manufacturing processes to address these issues, which may not be successful. This could jeopardize our ability to
commence COVAXIN sales and generate revenue, if approved.

If  our  third-party  manufacturing  partners  cannot  successfully  manufacture  material  that  conforms  to  our  specifications  and  the  strict  regulatory
requirements  of  the  FDA  or  another  comparable  foreign  regulatory  authorities  in  other  jurisdictions,  we  may  not  be  able  to  rely  on  our  third-party
manufacturing  partners'  facilities  for  the  manufacture  of  COVAXIN,  if  approved.  If  the  FDA  or  another  comparable  regulatory  authority  finds  their
facilities inadequate for the manufacture of COVAXIN, or if such facilities are subject to enforcement action in the future or are otherwise inadequate, we
may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for, or market
COVAXIN. If we are unable to obtain and maintain adequate supply of COVAXIN, our development and commercialization efforts would be impaired.

We expect to rely on our qualified suppliers and other third parties to manufacture clinical supplies of our product candidates and commercial supplies of
our  products,  if  and  when  approved  for  marketing  by  applicable  regulatory  authorities,  as  well  as  for  packaging,  serialization,  storage,  distribution,  and
other production logistics. We, however, may not succeed in our efforts to establish manufacturing relationships or other alternative arrangements for any
of our product candidates, components, and programs, or may be unable to do so on commercially favorable terms. If we are unable to enter into such
agreements  on  commercially  favorable  terms,  our  future  profit  margins  would  be  adversely  affected  and  our  ability  to  commercialize  any  products  that
receive marketing approval on a timely and competitive basis would be impaired. As a result, our business, financial condition, and results of operations
would be materially adversely affected.

If  the  manufacturers  upon  whom  we  rely  fail  to  produce  our  product  candidates  or  product  components  pursuant  to  the  terms  of  contractual
arrangements with us or fail to comply with stringent regulations applicable to biotechnology manufacturers, we may face delays in the development
and commercialization of, or be unable to meet demand for, our product candidates, if approved, and may lose potential revenues.

As with the third parties on which we rely or expect to rely for our preclinical activities and clinical trials, we have agreements governing the activities of
our manufacturers but have limited influence and control over their actual performance and activities. Our third-party manufacturers are not our employees,
and except for remedies available to us under our agreements with such third parties, we cannot control whether or not they devote sufficient time and
resources  to  our  manufacturing  requirements.  If  these  third-party  manufacturers  do  not  successfully  carry  out  their  contractual  duties,  meet  expected
deadlines or manufacture our product candidates in accordance with regulatory requirements, and if there are disagreements between us and such parties,
clinical development or marketing approval of our product candidates could be delayed.

The manufacture of biotechnology products requires significant expertise and capital investment, including the development of advanced manufacturing
techniques and process controls. Manufacturers of therapeutics often encounter difficulties in production, particularly in scaling up initial production. These
problems include difficulties with production costs and yields, quality control, including stability of the product candidate and quality assurance testing,
shortages of qualified personnel, and compliance with strictly enforced federal, state, and foreign regulations. If our manufacturers were to encounter any
of these difficulties and were unable to perform as agreed, our ability to provide product candidates to patients in our clinical trials and for commercial use,
if approved, would be jeopardized.

In addition, all manufacturers of our product candidates and therapeutic substances must comply with current GMP requirements enforced by the FDA that
are applicable to both finished products and their active components used for both, clinical and commercial supply. The FDA enforces these requirements
through its facilities inspection program. Our manufacturers must be approved by the FDA pursuant to inspections that will be conducted after we submit
our marketing applications to the agency. Our manufacturers will also be subject to continuing FDA and other regulatory authority inspections

68

Table of Contents

should we receive marketing approval. Further, we, in cooperation with our contract manufacturers, must supply all necessary CMC documentation to the
FDA in support of a marketing application on a timely basis.

The current GMP requirements include quality control, quality assurance, and the maintenance of records and documentation. Manufacturers of our product
candidates, therapeutic substances, and the active pharmaceutical ingredients necessary to produce our product candidates may be unable to comply with
our specifications, current GMP requirements, and with other FDA, state, and foreign regulatory requirements. Poor control of production processes can
lead to the introduction of adventitious agents or other contaminants, or to inadvertent changes in the properties or stability of a product candidate that may
not be detectable in final product testing. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the
strict  regulatory  requirements  of  the  FDA  or  other  regulatory  authorities,  they  will  not  be  able  to  secure  or  maintain  regulatory  approval  for  their
manufacturing  facilities.  Any  such  deviations  may  also  require  remedial  measures  that  may  be  costly  and/or  time-consuming  for  us  or  a  third  party  to
implement and that may include the temporary or permanent suspension of a clinical trial or commercial sales or the temporary or permanent closure of a
facility. Any resulting delays in obtaining products, if approved, or product candidates that comply with the applicable regulatory requirements may result
in delays to clinical trials, product approvals, and commercialization. It may also require that we conduct additional studies.

While we are ultimately responsible for the manufacture of our product candidates, other than through our contractual arrangements, we have little control
over our manufacturers’ compliance with these regulations and standards. A failure to comply with the applicable regulatory requirements may result in
regulatory enforcement actions against our manufacturers or us, including fines and civil and criminal penalties, including imprisonment, suspension or
restrictions of production, injunctions, delays, withdrawal or denial of product approval or supplements to approved products, clinical holds or termination
of clinical studies, warning or untitled letters, Form 483s, regulatory authority communications warning the public about safety issues with the product,
refusal  to  permit  the  import  or  export  of  the  products,  product  seizure,  detention,  or  recall,  operating  restrictions,  suits  under  the  civil  FCA,  corporate
integrity  agreements,  or  consent  decrees.  Depending  on  the  severity  of  any  potential  regulatory  action,  our  clinical  or  commercial  supply  could  be
interrupted or limited, which could have a material adverse effect on our business.

Any problems or delays we experience in preparing for commercial-scale manufacturing of a product candidate or component, including manufacturing
validation, may result in a delay in FDA approval or commercial launch, if approved, of the product candidate or may impair our ability to manufacture
commercial  quantities  or  such  quantities  at  an  acceptable  cost,  which  could  result  in  the  delay,  prevention,  or  impairment  of  commercialization  of  our
product candidates and could adversely affect our business. The risks associated with any problems or delays may be greater should the U.S. government
impose restrictions relating to goods manufactured in or imported from China.

We  or  our  third-party  manufacturers  may  also  encounter  shortages  in  the  materials  necessary  to  produce  our  product  candidates  in  the  quantities
needed for our clinical trials or, if our product candidates are approved, in sufficient quantities for commercialization.

We  or  our  third-party  manufacturers  may  also  encounter  shortages  in  the  raw  materials,  therapeutic  substances,  or  active  pharmaceutical  ingredients
necessary to produce our product candidates in the quantities needed for our clinical trials or, if our product candidates are approved, in sufficient quantities
for  commercialization  or  to  meet  an  increase  in  demand.  Such  shortages  may  occur  for  a  variety  of  reasons,  including  capacity  constraints,  delays  or
disruptions in the market, and shortages caused by the purchase of such materials by our competitors or others. We or our third-party manufacturers' failure
to  obtain  the  raw  materials,  therapeutic  substances,  or  active  pharmaceutical  ingredients  necessary  to  manufacture  sufficient  quantities  of  our  product
candidates  may  cause  the  manufacturers  to  fail  to  deliver  the  required  commercial  quantities  of  our  product  candidates  on  a  timely  basis  and  at
commercially reasonable prices. If such failure occurs, we would likely be unable to meet the demand for our products, if approved, and we would lose
potential revenues.

The number of available, qualified third-party manufactures is limited, and if we are compelled to locate an alternative manufacturing partner, our
product development activities and commercialization could be delayed and additional expense would be incurred.

There are a limited number of manufacturers that operate under current GMP regulations, that are both capable of manufacturing for us and willing to do
so, and therefore our product candidates may compete with other products and product candidates for access to manufacturing facilities. Moreover, because
our product candidates must be manufactured under sterile conditions, the number of manufacturers who can meet this requirement are even more limited.
If  our  existing  third-party  manufacturers,  or  the  third  parties  that  we  engage  in  the  future  to  manufacture  a  product,  if  approved,  or  component  for
commercial sale or for any clinical trials we expect to initiate in the future should cease to continue to do so for any reason

69

Table of Contents

(including the termination of our agreements with such manufacturers, which can occur for a variety of reasons, or the bankruptcy of such manufacturers),
it  would  be  difficult  to  obtain  a  suitable  alternative  manufacturer.  We  would  likely  experience  delays  in  obtaining  sufficient  quantities  of  our  product
candidates  for  us  to  meet  commercial  demand  or  to  advance  our  clinical  trials  while  we  identify  and  qualify  replacement  suppliers.  Any  change  in  our
manufacturers  could  be  costly  because  the  commercial  terms  of  any  new  arrangement  could  be  less  favorable  and  because  the  expenses  relating  to  the
transfer of necessary technology and processes could be significant.

If the FDA or a comparable foreign regulatory authority inspects the facilities for the manufacture of our product candidates and finds that they are not in
compliance with current GMP regulations now or in the future, we may need to find alternative manufacturing facilities. Any new manufacturers would
need to either obtain or develop the necessary manufacturing know-how, and obtain the necessary equipment and materials, which may take substantial
time and investment. We must also receive FDA approval for the use of any new manufacturers for commercial supply. Any such developments would
significantly impact our ability to develop, obtain, and maintain regulatory authorization or approval for or market our product candidates, if approved.

The  number  of  available  third-party  facilities  may  also  be  further  limited  by  natural  disasters,  such  as  pandemics,  including  the  ongoing  COVID-19
pandemic, floods, fire, or such facilities could face manufacturing issues, such as contamination or regulatory findings following a regulatory inspection of
such facility. In such instances, an appropriate replacement third-party relationship may not be readily available to us or on acceptable terms, which would
cause additional delays and increased expense and may have a material adverse effect on our business.

We  may  seek  to  collaborate  with  third  parties  for  the  development  or  commercialization  of  our  product  candidates.  We  may  not  be  successful  in
establishing  or  maintaining  collaborative  relationships,  any  of  which  could  adversely  affect  our  ability  to  develop  and  commercialize  our  product
candidates.

We are in an agreement with CanSinoBIO for the development and commercialization of our modifier gene therapy platform and with Bharat Biotech for
the  development  and  commercialization  of  COVAXIN  in  the  North  American  market.  In  the  future,  we  may  seek  to  enter  into  additional  collaboration
arrangements with pharmaceutical or biotechnology companies for the development or commercialization of other product candidates. We may utilize a
variety of types of collaboration, distribution, and other marketing arrangements with third parties to develop and commercialize our product candidates,
both inside and outside the United States. In particular, we may enter into arrangements with third parties to perform certain services in the United States or
other countries if we do not establish our own sales, marketing, and distribution capabilities in the such countries, or if we determine that such third-party
arrangements  are  otherwise  beneficial.  We  may  also  consider  potential  collaborative  partnership  opportunities  for  sales,  marketing,  distribution,
development,  or  licensing  or  broader  collaboration  arrangements,  including  with  mid-size  and  large  pharmaceutical  companies,  regional  and  national
pharmaceutical companies, and biotechnology companies.

The  success  of  our  current  and  future  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 collaboration arrangements. Accordingly, with respect
to any such arrangements with any third parties, we will likely have limited control over the amount and timing of resources that our collaborators dedicate
to the development or commercialization of our product candidates. Our ability to generate revenues from these arrangements will depend in part on our
collaborator's abilities and efforts to successfully perform the functions assigned to them in these arrangements.

Moreover, disagreements between parties to a collaboration arrangement regarding clinical development and commercialization matters can lead to delays
in  the  development  process  or  commercialization  of  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. Moreover, collaborations with pharmaceutical
companies and other third parties are often terminated or allowed to expire. Any such termination or expiration would adversely affect us financially and
could harm our business reputation.

Our current and future collaborations may pose a number of additional risks, including the following:

•

collaborators  may  not  pursue  development  of  product  candidates  and  commercialization  of  any  product  candidates  that  achieve  regulatory
approval  or  may  elect  not  to  continue  or  renew  development  or  commercialization  programs  based  on  clinical  trial  results,  changes  in  the
collaborators’ strategic focus or available funding, or external factors, such as an acquisition, that divert resources or create competing priorities;

collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product candidate,
repeat or conduct new clinical trials, or require a new formulation of a product candidate for clinical testing;

collaborators could fail to make timely regulatory submissions for a product candidate;

collaborators  may  not  comply  with  all  applicable  regulatory  requirements  or  may  fail  to  report  safety  data  in  accordance  with  all  applicable
regulatory requirements, which could subject them or us to regulatory enforcement actions;

collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our product candidates
if the collaborators believe that competitive products are more likely to be successfully developed or can be commercialized under terms that are
more economically attractive than ours;

product candidates discovered in collaboration with us may be viewed by our collaborators as competitive with their own product candidates or
products, which may cause collaborators to cease to devote resources to the commercialization of our product candidates;

a collaborator with marketing and distribution rights to one or more of our product candidates that achieve regulatory approval may not commit
sufficient resources to the marketing and distribution of such product candidate or product;

disagreements with collaborators, including disagreements over proprietary rights, contract interpretation, or the preferred course of development,
might  cause  delays  or  termination  of  the  research,  development,  or  commercialization  of  product  candidates,  might  lead  to  additional
responsibilities for us with respect to product candidates, or might result in litigation or arbitration, any of which would be time consuming and
expensive;

collaborators  may  not  properly  maintain  or  defend  our  intellectual  property  rights  or  may  use  our  proprietary  information  in  such  a  way  as  to
invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential litigation;

collaborators may infringe the intellectual property rights of third parties or fail to maintain intellectual property rights which they license to us,
which may expose us to litigation and potential liability; and

collaborations may be terminated for the convenience of the collaborator and, if terminated, we could be required to raise additional capital to
pursue further development or commercialization of the applicable product candidates.

Collaboration  agreements  may  not  lead  to  development  or  commercialization  of  our  product  candidates  in  the  most  efficient  manner,  or  at  all.  If  any
collaborations  do  not  result  in  the  successful  development  and  commercialization  of  our  product  candidates  or  if  one  of  our  collaborators  subsequently
terminates our agreement with us, we may not receive any future research funding, milestone, or royalty payments under the collaboration, as applicable. If
we do not receive the funding we expect under the agreements, our development of our product candidates could be delayed, and we may need additional
resources  to  develop  our  product  candidates  and  our  product  platform.  All  of  the  risks  relating  to  product  development,  regulatory  approval,  and
commercialization described in this report also apply to the activities of our collaborators.

Additionally,  if  any  collaborator  of  ours  is  involved  in  a  business  combination,  the  collaborator  might  de-emphasize  or  terminate  development  or
commercialization  of  any  product  candidate  licensed  to  them  by  us.  If  one  of  our  collaborators  terminates  its  agreement  with  us,  we  may  find  it  more
difficult to attract new collaborators and our reputation in the business and financial communities could be adversely affected.

Should  we  desire  to  pursue  a  collaboration  agreement  but  are  not  able  to  establish  collaborations,  we  may  have  to  alter  our  development  and
commercialization plans and our business could be adversely affected.

For  some  of  our  product  candidates,  we  may  decide  to  collaborate  with  pharmaceutical  or  biotechnology  companies  for  the  development  and  potential
commercialization  of  those  product  candidates.  We  face  significant  competition  in  seeking  appropriate  collaborators  and  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 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, if approved, the potential of competing products,
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.  We  may  also  be  restricted  under  future  license  agreements  from  entering  into
agreements on certain terms with potential collaborators. Collaborations are complex and time-consuming to negotiate and document. Should we desire to

71

Table of Contents

pursue a collaboration agreement but are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all, we may
have to curtail the development of a product candidate, reduce or delay our development program or one or more of our other development programs, delay
our  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  fail  to  enter  into  collaborations  and  do  not  have  sufficient  funds  or  expertise  to  undertake  the
necessary development and commercialization activities, we may not be able to further develop our product candidates or bring them to market or continue
to develop our product platform and our business may be materially and adversely affected.

Risks Related to Legal and Compliance Matters

We are currently, and may in the future be, subject to securities litigation, which is expensive and could divert management attention.

In  June  2021,  a  securities  class  action  lawsuit  was  filed  against  us  and  certain  of  our  agents  in  the  U.S.  District  Court  for  the  Eastern  District  of
Pennsylvania ("Court") (Case No. 2:21-cv-02725) that purported to state a claim for alleged violations of Sections 10(b) and 20(a) of the Exchange Act and
Rule 10b-5 promulgated thereunder, based on statements made by us concerning the announcement of our decision to pursue the submission of a BLA for
COVAXIN for adults ages 18 years and older rather than pursuing an EUA for the vaccine candidate. In July 2021, a second securities class action lawsuit
was filed against us and certain of our agents in the Court (Case No. 2:21-cv-03182) that also purported to state a claim for alleged violations of Sections
10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder, based on the same statements as the first complaint. In March 2022, the
Court  consolidated  these  two  related  securities  class  action  lawsuits  and  appointed  Andre  Galan  Bernd  Benayon  to  serve  as  lead  plaintiff.  The  lead
plaintiff's amended complaint was filed in June 2022. We filed a motion to dismiss the amended complaint in August 2022. The lead plaintiff's opposition
to the motion to dismiss was filed in October 2022. We filed our reply in support of the motion to dismiss in November 2022. Oral argument on the motion
to dismiss took place in January 2023 and no decision has been made to date by the Court. As with any litigation, we cannot predict the outcome with
certainty, but we expect to provide further updates on the status of the motion to dismiss as available.

In August 2021, a stockholder derivative lawsuit was filed derivatively on behalf of our company against certain of our agents and the nominal defendant
Ocugen in the Court (Case No. 2:21-cv-03876) that purported to state a claim for breach of fiduciary duty and contribution for violations of Sections 10(b)
and  21(d)  of  the  Exchange  Act,  based  on  facts  and  circumstances  relating  to  the  securities  class  action  lawsuits  and  seeking  contribution  and
indemnification in connection with claims asserted in the securities class action lawsuits. In September 2021, a second stockholder derivative lawsuit was
filed derivatively on behalf of our company against certain of our agents and the nominal defendant Ocugen in the Court (Case No. 2:21-cv-04169) that
purported to state a claim for breach of fiduciary duties, unjust enrichment, abuse of control, waste of corporate assets, and contribution for violations of
Sections 10(b) and 21(d) of the Exchange Act, based on the same allegations as the first complaint. The parties to both stockholder derivative lawsuits have
stipulated to the consolidation of the two stockholder derivative lawsuits and also have submitted to the Court in each action a proposed order requesting a
stay of the litigation pending a decision on any motion to dismiss filed in the securities class action lawsuits, which the Court entered in April 2022.

The complaints seek unspecified damages, interest, attorneys’ fees, and other costs. We believe that the lawsuits are without merit and intend to vigorously
defend  against  them.  At  this  time,  no  assessment  can  be  made  as  to  their  likely  outcome  or  whether  the  outcome  will  be  material  to  us.  We  may  also
become  subject  to  additional  securities  class  action  lawsuits  in  the  future.  This  risk  is  especially  relevant  for  us  because  life  sciences  companies  have
experienced significant stock price volatility in recent years.

The cost of defending against these types of claims against us or the ultimate resolution of such claims, whether by settlement or adverse court decision,
may harm our business. Further, potential claimants may be encouraged to bring lawsuits based on a settlement from us or adverse court decisions against
us. We cannot currently assess the likely outcome of such lawsuits, but the commencement and/or resolution of such lawsuits (particularly if the outcome
were negative), could have a material adverse effect on our reputation, results of operations, financial condition, and cash flows. They could also cause a
decline in the market price of our common stock.

If we fail to comply with federal and state healthcare laws, including fraud, abuse, and health and other information privacy and security laws, we
could face substantial penalties and our business, financial condition, results of operations, and prospects could be adversely affected.

As a biotechnology company, we are subject to many federal and state healthcare laws, such as the federal Anti-Kickback Statute, the federal civil and
criminal FCA, the civil monetary penalties statute, the Medicaid Drug Rebate statute and other

72

Table of Contents

price reporting requirements, the VHCA, the HIPAA, the FCPA, the ACA, and similar state laws. We may also be subject to laws regarding transparency
and patient privacy. Even though we do not and will not control referrals of healthcare services or bills directly to Medicare, Medicaid, or other third-party
payors, certain federal and state healthcare laws, and regulations pertaining to fraud and abuse, reimbursement programs, government procurement, and
patients’ rights are and will be applicable to our business.

It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations, or case law
involving  applicable  fraud,  abuse,  or  other  healthcare  laws  and  regulations.  If  we  or  our  operations  are  found  to  be  in  violation  of  any  federal  or  state
healthcare  law,  or  any  other  governmental  laws  or  regulations  that  applies  to  us,  we  may  be  subject  to  penalties,  including  civil,  criminal,  and
administrative penalties, damages, fines, imprisonment, disgorgement, suspension and debarment from government contracts, and refusal of orders under
existing  government  contracts,  exclusion  from  participation  in  U.S.  federal  or  state  health  care  programs,  corporate  integrity  agreements,  and  the
curtailment or restructuring of our operations, any of which could materially adversely affect our ability to operate our business and our financial results.
Although an effective compliance program can mitigate the risk of investigation and prosecution for violations of these laws, the risks cannot be entirely
eliminated. Moreover, achieving and sustaining compliance with applicable federal and state privacy, security, reimbursement, and fraud laws may prove
costly. Any action against us for the violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and
divert our management’s attention from the operation of our business.

Healthcare legislative or regulatory reform measures may have a negative impact on our business and results of operations.

The United States and many foreign jurisdictions have enacted or proposed legislative and regulatory changes affecting the healthcare system. The United
States government, state legislatures, and foreign governments also have shown significant interest in implementing cost-containment programs to limit the
growth of government-paid healthcare costs, including price controls, restrictions on reimbursement, and requirements for substitution of generic products
for  branded  prescription  products.  In  recent  years,  Congress  has  considered  reductions  in  Medicare  reimbursement  levels  for  products  administered  by
physicians.

CMS,  the  agency  that  administers  the  Medicare  and  Medicaid  programs,  also  has  authority  to  revise  reimbursement  rates  and  to  implement  coverage
restrictions for some products. Cost reduction initiatives and changes in coverage implemented through legislation or regulation could decrease utilization
of and reimbursement for any approved products. While Medicare regulations apply only to drug benefits for Medicare beneficiaries, private payers often
follow Medicare coverage policy and payment limitations in setting their own reimbursement rates. Therefore, any reduction in reimbursement that results
from federal legislation or regulation may result in a similar reduction in payments from private payers.

The ACA substantially changed the way healthcare is financed by both governmental and private insurers, and significantly impacts the pharmaceutical
industry.  The  ACA  is  intended  to  broaden  access  to  health  insurance,  reduce  or  constrain  the  growth  of  healthcare  spending,  enhance  remedies  against
healthcare  fraud  and  abuse,  add  new  transparency  requirements  for  healthcare  and  health  insurance  industries,  impose  new  taxes  and  fees  on
pharmaceutical and medical device manufacturers, and impose additional health policy reforms. Among other things, the Affordable Care Act expanded
manufacturers’ rebate liability under the MDRP by increasing the minimum Medicaid rebate for both branded and generic products, expanded the 340B
program,  and  revised  the  definition  of  AMP,  which  could  increase  the  amount  of  Medicaid  rebates  manufacturers  are  required  to  pay  to  states.  The
legislation also extended Medicaid rebates, previously due only on fee-for-service Medicaid utilization, to include the utilization of Medicaid managed care
organizations as well and created an alternative rebate formula for certain new formulations of certain existing products that is intended to increase the
amount  of  rebates  due  on  those  products.  On  February  1,  2016,  CMS  issued  final  regulations  to  implement  the  changes  to  the  MDRP  under  the  ACA.
These regulations became effective on April 1, 2016. Since that time, there have been significant ongoing efforts to modify or eliminate the ACA. The Tax
Act  enacted  on  December  22,  2017,  repealed  the  shared  responsibility  payment  for  individuals  who  fail  to  maintain  minimum  essential  coverage  under
section 5000A of the Internal Revenue Code of 1986, as amended, of the Code, commonly referred to as the individual mandate.

Other legislative changes have been proposed and adopted since the passage of the ACA. The Budget Control Act of 2011, among other things, created the
Joint Select Committee on Deficit Reduction to recommend proposals in spending reductions to Congress. The Joint Select Committee did not achieve its
targeted deficit reduction of an amount greater than $1.2 trillion for the fiscal years 2012 through 2021, triggering the legislation’s automatic reductions to
several government programs. These reductions included aggregate reductions to Medicare payments to healthcare providers of up to 2.0% per fiscal year,
which went into effect in April 2013. Subsequent legislation extended the 2.0% reduction, on average, to 2030 unless additional Congressional action is
taken. However, pursuant to the CARES Act, the 2.0% Medicare sequester reductions were suspended from May 1, 2020 through March 31, 2022 due to
the COVID-19 pandemic. As of July 1, 2022, the 2.0% sequester reduction resumed. The sequester will remain in place through 2030. On January 2, 2013,
the American Taxpayer Relief Act was signed

73

Table of Contents

into law, which, among other things, reduced Medicare payments to several types of providers, including hospitals, imaging centers and cancer treatment
centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. The IRA contains
substantial  drug  pricing  reforms,  including  the  establishment  of  a  drug  price  negotiation  program  within  the  U.S.  Department  of  Health  and  Human
Services that would require manufacturers to charge a negotiated “maximum fair price” for certain selected drugs or pay an excise tax for noncompliance,
the establishment of rebate payment requirements on manufacturers of certain drugs payable under Medicare Parts B and D to penalize price increases that
outpace inflation, and requires manufacturers to provide discounts on Part D drugs. Substantial penalties can be assessed for noncompliance with the drug
pricing  provisions  in  the  IRA.  The  IRA  could  have  the  effect  of  reducing  the  prices  we  can  charge  and  reimbursement  we  receive  for  our  products,  if
approved,  thereby  reducing  our  profitability,  and  could  have  a  material  adverse  effect  on  our  financial  condition,  results  of  operations,  and  growth
prospects. The effect of IRA on our business and the pharmaceutical industry in general is not yet known.

The ACA has been subject to challenges in the courts. On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in
its  entirety  because  the  “individual  mandate”  was  repealed  by  Congress.  On  December  18,  2019,  the  Fifth  Circuit  U.S.  Court  of  Appeals  held  that  the
individual mandate is unconstitutional and remanded the case to the Texas District Court to reconsider its earlier invalidation of the entire ACA. An appeal
was taken to the U.S. Supreme Court. On June 17, 2021, the Supreme Court ruled that the plaintiffs lacked standing to challenge the law as they had not
alleged personal injury traceable to the allegedly unlawful conduct. As a result, the Supreme Court did not rule on the constitutionality of the ACA or any
of its provisions.

Further changes to and under the ACA remain possible, but it is unknown what form any such changes or any law proposed to replace or revise the ACA
would  take,  and  how  or  whether  it  may  affect  our  business  in  the  future.  We  expect  that  changes  to  the  ACA,  the  Medicare  and  Medicaid  programs,
changes allowing the federal government to directly negotiate prices and changes stemming from other healthcare reform measures, especially with regard
to healthcare access, financing, or other legislation in individual states, could have a material adverse effect on the healthcare industry.

At  the  state  level,  legislatures  have  increasingly  passed  legislation  and  implemented  regulations  designed  to  control  pharmaceutical  product  pricing,
including  price  or  patient  reimbursement  constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency
measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

We expect that additional federal, state, and foreign healthcare reform measures will be adopted in the future, any of which could limit the amounts that
federal  and  state  governments  will  pay  for  healthcare  products  and  services,  which  could  result  in  limited  coverage  and  reimbursement,  and  reduced
demand for our products, once approved, or additional pricing pressures.

Our  employees,  independent  contractors,  consultants,  commercial  partners,  principal  investigators,  or  CDMOs  may  engage  in  misconduct  or  other
improper activities, including noncompliance with regulatory standards and requirements, which could have a material adverse effect on our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees, independent contractors, consultants, commercial partners,
manufacturers, investigators, or CDMOs could include intentional, reckless, negligent, or unintentional failures to (i) comply with FDA regulations or other
similar  regulatory  requirements,  (ii)  comply  with  manufacturing  standards,  including  current  GMP  requirements,  (iii)  comply  with  applicable  fraud  and
abuse laws, (iv) comply with federal and state data privacy, security, fraud and abuse, and other healthcare laws and regulations in the United States and
abroad, (v) provide accurate information to the FDA, (vi) properly calculate pricing information required by federal programs, (vii) comply with federal
procurement rules or contract terms, (viii) report financial information or data accurately, or (ix) disclose unauthorized activities to us. This misconduct
could also involve the improper use or misrepresentation of information obtained in the course of clinical trials, which could result in regulatory sanctions
and serious harm to our reputation.

It is not always possible to identify and deter this type of misconduct, and the precautions we take to detect and prevent this activity may not be effective in
controlling  unknown  or  unmanaged  risks  or  losses  or  in  protecting  us  from  governmental  investigations  or  other  actions  or  lawsuits  stemming  from  a
failure to be in compliance with such laws or regulations.

If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant
impact  on  our  business  and  financial  results,  including,  without  limitation,  the  imposition  of  significant  civil,  criminal  and  administrative  penalties,
damages, monetary fines, disgorgements, possible exclusion from participation in Medicare, Medicaid, and other federal healthcare programs, individual
imprisonment,  contractual  damages,  reputational  harm,  diminished  profits  and  future  earnings,  additional  reporting  requirements  and  oversight  if  we
become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and

74

Table of Contents

curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

We are subject to anti-corruption laws, as well as export control laws, customs laws, sanctions laws, and other laws governing our operations. If we fail
to  comply  with  these  laws,  we  could  be  subject  to  civil  or  criminal  penalties,  other  remedial  measures  and  legal  expenses,  or  be  precluded  from
developing, manufacturing, and selling certain products outside the United States, which could adversely affect our business, results of operations, and
financial condition.

If we expand our operations outside of the United States, we must dedicate additional resources to comply with anti-corruption laws, including the Bribery
Act, the FCPA, and other anti-corruption laws that apply to countries where we do business and may do business in the future. The Bribery Act, FCPA, and
these other laws generally prohibit us, our officers, and our employees and intermediaries from bribing, being bribed, or making other prohibited payments
to government officials or other persons to obtain or retain business or gain some other business advantage.

Compliance  with  the  FCPA,  in  particular,  is  expensive  and  difficult,  particularly  in  countries  in  which  corruption  is  a  recognized  problem.  The  FCPA
presents particular challenges in the pharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and other
hospital employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials and other work have been deemed to be
improper payments to government officials and have led to FCPA enforcement actions. The FCPA also obligates companies whose securities are listed in
the United States to comply with certain accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all
transactions  of  the  corporation,  including  international  subsidiaries,  and  to  devise  and  maintain  an  adequate  system  of  internal  accounting  controls  for
international operations.

We may in the future operate in jurisdictions that pose a high risk of potential Bribery Act or FCPA violations, and we may participate in collaborations and
relationships with third parties whose actions could potentially subject us to liability under the Bribery Act, FCPA, or local anti-corruption laws. We are
also  subject  to  other  laws  and  regulations  governing  our  international  operations,  including  regulations  administered  by  the  governments  of  the  United
Kingdom,  the  United  States,  Canada,  and  authorities  in  the  European  Union,  including  applicable  export  control  regulations,  economic  sanctions  on
countries and persons, customs requirements, and currency exchange regulations, collectively referred to as the Trade Control laws. In addition, various
laws, regulations, and executive orders also restrict the use and dissemination outside of the United States, or the sharing with certain non-U.S. nationals, of
information classified for national security purposes, as well as certain products and technical data relating to those products. If we expand our presence
outside of the United States, it will require us to dedicate additional resources to comply with these laws, and these laws may preclude us from developing,
manufacturing, or selling certain products and product candidates outside of the United States, which could limit our growth potential and increase our
development costs.

If we are not in compliance with the Bribery Act, the FCPA, and other anti-corruption laws or Trade Control laws, we may be subject to criminal and civil
penalties,  disgorgement  and  other  sanctions  and  remedial  measures,  and  legal  expenses,  which  could  have  an  adverse  impact  on  our  business,  financial
condition,  results  of  operations,  and  liquidity.  The  SEC  also  may  suspend  or  bar  issuers  from  trading  securities  on  U.S.  exchanges  for  violations  of  the
FCPA’s accounting provisions. Any investigation of any potential violations of the Bribery Act, the FCPA, other anti-corruption laws or Trade Control laws
by U.K., U.S., or other authorities could also have an adverse impact on our reputation, our business, results of operations, and financial condition.

Risks Related to Our Intellectual Property

We may be unable to obtain and maintain patent protection for our technology and product candidates, or the scope of the patent protection obtained
may not be sufficiently broad or enforceable, such that our competitors could develop and commercialize technology and products similar or identical
to ours, and our ability to successfully commercialize our technology and product candidates may be impaired.

Our  success  depends  in  large  part  on  our  ability  to  obtain  and  maintain  patent  protection  in  the  United  States  and  other  countries,  with  respect  to  our
proprietary  technology  and  product  candidates.  We  have  sought  to  protect  our  proprietary  position  by  filing  in  the  United  States  and  in  certain  foreign
jurisdictions, patent applications related to our novel technologies and product candidates.

The  patent  prosecution  process  is  expensive  and  time-consuming,  and  we  may  not  have  filed,  maintained,  or  prosecuted  and  may  not  be  able  to  file,
maintain, and prosecute all necessary or desirable patents or patent applications at a reasonable cost or

75

Table of Contents

in a timely manner. We may also fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection.

The patent position of pharmaceutical and biotechnology companies generally is highly uncertain, involves complex legal and factual questions, and has in
recent  years  been  the  subject  of  much  litigation.  As  a  result,  the  issuance,  scope,  validity,  enforceability,  and  commercial  value  of  our  patent  rights  are
highly uncertain. Our pending and future patent applications may fail to result in issued patents in the United States or in other foreign countries which
protect our technology or product candidates, or which effectively prevent others from commercializing competitive technologies and products. In addition,
the laws of foreign countries may not protect our rights to the same extent as the laws of the United States, and the standards applied by the USPTO and
foreign patent offices in granting patents are not always applied uniformly or predictably. For example, unlike patent law in the United States, European
patent law precludes the patentability of methods of treatment of the human body and imposes substantial restrictions on the scope of claims it will grant,
of broader than specifically disclosed embodiments. 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 filing, or in some cases not at all. Therefore, we
cannot be certain whether we or our licensors were the first to make the inventions claimed in our owned or licensed patents or pending patent applications,
or that we or our licensors were the first to file for patent protection of such inventions. Databases for patents and publications, and methods for searching
them, are inherently limited so we may not know the full scope of all issued and pending patent applications. As a result, the issuance, scope, validity,
enforceability, and commercial value of our patent rights are uncertain. Our pending and future patent applications may not result in patents being issued
which protect our technology or product candidates, in whole or in part, or which effectively prevent others from commercializing competitive technologies
and products. In particular, during prosecution of any patent application, the issuance of any patents based on the application may depend upon our ability
to generate additional preclinical or clinical data that support the patentability of our proposed claims. We may not be able to generate sufficient additional
data on a timely basis, or at all. Moreover, changes in either the patent laws or interpretation of the patent laws in the United States and other countries may
diminish the value of our patents or narrow the scope of our patent protection.

Even if our owned and licensed patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection for
our proprietary technology and product candidates, prevent competitors from competing with us, or otherwise provide us with any competitive advantage.
Our competitors may be able to circumvent our owned or licensed patents by developing similar or alternative technologies or products in a non-infringing
manner. In some instances, we may need to license additional patents and trade secrets to commercialize our product candidates in certain territories.

The issuance of a patent is not conclusive as to our inventorship, ownership, scope, validity, or enforceability, and our owned and licensed patents may be
challenged  in  the  courts  or  patent  offices  in  the  United  States  and  abroad.  Such  challenges  may  result  in  loss  of  exclusivity  or  in  patent  claims  being
narrowed, invalidated, or held unenforceable, 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  product  candidates.  Given  the  amount  of  time
required for the development, testing, and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly
after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing
products similar or identical to ours.

Patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or
defense of our issued patents.

In  2011,  the  Leahy-Smith  America  Invents  Act  (the  "Leahy-Smith  Act")  was  signed  into  law.  The  Leahy-Smith  Act  includes  a  number  of  significant
changes  to  U.S.  patent  law.  These  include  provisions  that  affect  the  way  patent  applications  are  prosecuted  and  may  also  affect  patent  litigation.  The
USPTO developed new regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law
associated with the Leahy-Smith Act, and in particular, the first to file provisions, became effective in 2013. The first to file provisions limit the rights of an
inventor to patent an invention if not the first to file an application for patenting that invention, even if such invention was the first invention. The Leahy-
Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or
defense  of  our  issued  patents,  which  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of  operations,  and  prospects.  For
example, the Leahy-Smith Act created a new administrative tribunal known as the Patent Trial and Appeals Board ("PTAB"), that provides a venue for
companies to challenge the validity of competitor patents at a cost that is much lower than district court litigation and on timelines that are much faster.
Although it is not clear what, if any, long term impact the PTAB proceedings will have on the operation of our business, the outcome of patent challenge
proceedings before the PTAB since its inception in 2013 have resulted in the invalidation of many U.S. patent claims. The availability of the PTAB as a
lower-cost, faster, and potentially

76

Table of Contents

more  potent  tribunal  for  challenging  patents  could  therefore  increase  the  likelihood  that  our  own  patents  will  be  challenged,  thereby  increasing  the
uncertainties and costs of maintaining, defending, and enforcing them.

If we are not able to obtain patent term extension in the United States under the Hatch-Waxman Act and in foreign countries under similar legislation,
thereby potentially extending the term of our marketing exclusivity for our product candidates, our business may be materially harmed.

Depending upon the timing, duration, and specifics of FDA marketing approval of our product candidates, one of the U.S. patents covering each of such
product candidates or the use thereof may be eligible for up to five years of patent term extension under the Hatch-Waxman Act. The Hatch-Waxman Act
allows a maximum of one patent to be extended per FDA approved product to account for the patent term lost during the FDA regulatory review process. A
patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval and only those claims
covering such approved drug product, a method for using it, or a method for manufacturing it may be extended. Patent term extension also may be available
in certain foreign countries upon regulatory approval of our product candidates. Nevertheless, we may not be granted patent term extension either in the
United States or in any foreign country because of, for example, failing to exercise due diligence during the testing phase or regulatory review process,
failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy applicable requirements.
Moreover, the term of extension, as well as the scope of patent protection during any such extension, afforded by the governmental authority could be less
than we request.

If we are unable to obtain patent term extension or restoration, or the term of any such extension is less than we request, the period during which we will
have the right to exclusively market our product may be shortened and our competitors may obtain approval of competing products following our patent
expiration sooner, and our revenue could be reduced, possibly materially.

It is possible that we will not obtain patent term extension under the Hatch-Waxman Act for a U.S. patent covering one of our product candidates even
where that patent is eligible for patent term extension, or if we obtain such an extension, it may be for a shorter period than we had sought. Further, for our
licensed patents, we do not have the right to control prosecution, including filing with the USPTO, a petition for patent term extension under the Hatch-
Waxman Act. Thus, if one of our licensed patents is eligible for patent term extension under the Hatch-Waxman Act, we may not be able to control whether
a petition to obtain a patent term extension is filed, or obtained, from the USPTO.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time-consuming, and
unsuccessful.

Competitors and other third parties may infringe, misappropriate, or otherwise violate our owned and licensed patents, trade secrets, or other intellectual
property. As a result, to counter infringement, misappropriation, or unauthorized use, we may be required to file infringement or misappropriation claims or
other  intellectual  property  related  proceedings,  which  can  be  expensive  and  time-consuming.  Any  claims  we  assert  against  perceived  infringers  could
provoke  such  parties  to  assert  counterclaims  against  us  alleging  that  we  infringed  their  patents  or  that  our  asserted  patents  are  invalid.  In  addition,  in  a
patent infringement or other intellectual property related proceeding, a court may decide that a patent of ours is invalid or unenforceable, in whole or in
part, construe the patent’s claims narrowly or 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  proceeding  could  put  one  or  more  of  our  patents  at  risk  of  being  invalidated,  held
unenforceable, or interpreted narrowly, and could put any of our patent applications at risk of not yielding an issued patent. Furthermore, because of the
substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information or trade
secrets could be compromised by disclosure during this type of litigation.

We  may  be  subject  to  a  third-party  preissuance  submission  of  prior  art  to  the  USPTO,  or  become  involved  in  other  contested  proceedings  such  as
opposition, derivation, reexamination, inter partes review, post-grant review, or interference proceedings in the United States or elsewhere, challenging our
patent  rights  or  the  patent  rights  of  others.  An  adverse  determination  in  any  such  submission,  proceeding,  or  litigation  could  reduce  the  scope  of,  or
invalidate, our patent rights, allow third parties to commercialize our technology or product candidates 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 our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop, or
commercialize current or future product candidates.

In the United States, the FDA does not prohibit clinicians from prescribing an approved product for uses that are not described in the product’s labeling.
Although use of a product directed by off-label prescriptions may infringe our method-of-treatment

77

Table of Contents

patents,  the  practice  is  common  across  medical  specialties,  particularly  in  the  United  States,  and  such  infringement  is  difficult  to  detect,  prevent,  or
prosecute.

Third parties may initiate legal proceedings alleging that we are infringing, misappropriating, or otherwise violating their intellectual property rights,
the outcome of which would be uncertain and could have a material adverse effect on the success of our business.

Our commercial success depends upon our ability to develop, manufacture, market, and sell our product candidates and use our proprietary technologies
without infringing, misappropriating, or otherwise violating the intellectual property and other proprietary rights of third parties. There is a considerable
amount of intellectual property litigation in the biotechnology and pharmaceutical industries. We may become party to, or threatened with, infringement
litigation claims regarding our products and technology, including claims from competitors or from non-practicing entities that have no relevant product
revenue and against whom our own patent portfolio may have no deterrent effect. Moreover, we may become party to future adversarial proceedings or
litigation  regarding  our  patent  portfolio  or  the  patents  of  third  parties.  Such  proceedings  could  also  include  contested  post-grant  proceedings  such  as
oppositions, inter partes review, reexamination, interference, or derivation proceedings before the USPTO or foreign patent offices.

The  legal  threshold  for  initiating  litigation  or  contested  proceedings  is  low,  so  even  lawsuits  or  proceedings  with  a  low  probability  of  success  might  be
initiated and require significant resources to defend. Litigation and contested proceedings can also be expensive and time-consuming, and our adversaries
in  these  proceedings  may  have  the  ability  to  dedicate  substantially  greater  resources  to  prosecuting  these  legal  actions  than  we  do.  The  risks  of  being
involved in such litigation and proceedings may increase as our product candidates near commercialization and as we gain the greater visibility associated
with being a public company. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future.
We may not be aware of all such intellectual property rights potentially relating to our product candidates and their uses.

Thus, we do not know with certainty that any of our product candidates, or our development and commercialization thereof, do not and will not infringe or
otherwise violate any third party’s intellectual property.

If we are found to infringe, misappropriate, or otherwise violate a third party’s intellectual property rights, we could be required to obtain a license from
such  third  party  to  continue  developing  and  marketing  its  products  and  technology.  However,  we  may  not  be  able  to  obtain  any  required  license  on
commercially reasonable terms or at all. Even if we are able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the
same technologies licensed to us and could require us to make substantial licensing and royalty payments. We could be forced, including by court order, to
cease commercializing the infringing technology or product. In addition, we could be found liable for monetary damages, including treble damages and
attorneys’  fees  if  we  are  found  to  have  willfully  infringed  a  patent,  and  could  be  forced  to  indemnify  our  customers  or  collaborators.  A  finding  of
infringement could also result in an injunction that prevents us from commercializing our product candidates or forces us to cease some of our business
operations, which could materially harm our business. In addition, we may be forced to redesign our product candidates, seek new regulatory approvals,
and  indemnify  third  parties  pursuant  to  contractual  agreements.  Claims  that  we  have  misappropriated  confidential  information  or  trade  secrets  of  third
parties could have a similar negative impact on our business.

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.

Periodic maintenance, renewal, and annuity fees on any issued patent must be paid to the USPTO and foreign patent agencies in several stages or annually
over  the  lifetime  of  our  owned  and  licensed  patents  and  patent  applications.  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  certain
circumstances, we rely on our licensing partners to pay these fees to, or comply with the procedural and documentary rules of the relevant patent agency.
While  an  inadvertent  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  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 or our
licensors fail to maintain the patents and patent applications covering our product candidates, it would have a material adverse effect on our business.

78

Table of Contents

Certain  aspects  of  our  product  candidates  are  protected  by  patents  exclusively  licensed  from  other  companies  or  institutions.  If  these  third  parties
terminate their agreements with us or fail to maintain or enforce the underlying patents or licenses thereto, or we otherwise lose our rights to these
patents, our competitive position and our market share in the markets for any of our approved products will be harmed.

A  substantial  portion  of  our  patent  portfolio  is  in-licensed.  As  such,  we  are  party  to  license  agreements  and  certain  aspects  of  our  business  depend  on
patents  and/or  patent  applications  owned  by  other  companies  or  institutions.  For  example,  we  hold  exclusive  licenses  for  patent  families  relating  to
OCU400, OCU410, OCU410ST, and OCU200, and an exclusive license in the United States, Canada, and Mexico with respect to COVAXIN, an exclusive
license in the United States, Europe, Japan, South Korea, Australia, and China with respect an inhaled mucosal COVID-19 vaccine, and exclusive licenses
for patent families related to NeoCart.

Pursuant to the CU Agreement, which primarily relates to OCU200, we are responsible for and control the patent prosecution of all patent families licensed
under the CU Agreement.

Pursuant to the SERI Agreement, which relates to NHR genes NR1D1, NR2E3 (OCU400), RORA (OCU410 and OCU410ST), NUPR1, and NR2C1, from
and after December 19, 2017, we have the right to assume responsibility and control patent prosecution of licensed patent families relating to these NHR
genes. Additionally, we are responsible for and control patent prosecution for any patent applications developed in connection with the SERI Agreement
filed after December 19, 2017 that are owned jointly by us and SERI, or solely by us.

Pursuant  to  the  WU  Agreement,  which  relates  to  inhaled  mucosal  COVID-19  vaccines,  Washington  University  maintains  control  of  patent  preparation,
filing, prosecution, and maintenance, subject to our right to negotiate with WU after the first anniversary of the effective date of the WU Agreement to
assume  responsibility  for  and  control  of  the  prosecution  and  maintenance  of  the  patent  rights  throughout  the  Mucosal  Vaccine  Territory  in  Washington
University's name.

Our rights with respect to in-licensed patents and patent applications may be lost if the applicable license agreement expires or terminates. We are likely to
enter into additional license agreements to in-license patents and patent applications as part of the development of our business in the future, under which
we may not retain control of the preparation, filing, prosecution, maintenance, enforcement, and defense of such patents. If we are unable to maintain these
patent rights for any reason, our ability to develop and commercialize our product candidates could be materially harmed.

Our licensors may not successfully prosecute certain patent applications, the prosecution of which they control, under which we are licensed and on which
our  business  depends.  Even  if  patents  are  issued  from  these  applications,  our  licensors  may  fail  to  maintain  these  patents,  may  decide  not  to  pursue
litigation against third-party infringers, may fail to prove infringement, or may fail to defend against counterclaims of patent invalidity or unenforceability.
In some cases, our licensors may in-license certain patents licensed to us. If our licensors were to fail to maintain such licenses, we may need to obtain
additional licenses with respect to the applicable product candidates.

Risks with respect to parties from whom we have obtained intellectual property rights may also arise out of circumstances beyond our control. In spite of
our  best  efforts,  our  licensors  might  conclude  that  we  have  materially  breached  our  intellectual  property  agreements  and  might  therefore  terminate  the
intellectual  property  agreements,  thereby  removing  our  ability  to  market  products  covered  by  these  intellectual  property  agreements.  If  our  intellectual
property agreements are terminated, or if the underlying patents fail to provide the intended market exclusivity, our competitors would have the freedom to
seek  regulatory  approval  of,  and  to  market,  products  similar  or  identical  to  ours.  Moreover,  if  our  intellectual  property  agreements  are  terminated,  our
former  licensors  and/or  assignors  may  be  able  to  prevent  us  from  utilizing  the  technology  covered  by  the  licensed  or  assigned  patents  and  patent
applications. This could have a material adverse effect on our competitive business position and our business prospects.

Some intellectual property which we own or have licensed may have been discovered through government funded programs and thus may be subject to
federal regulations such as “march-in” rights, certain reporting requirements, and a preference for U.S. industry. Compliance with such regulations
may limit our exclusive rights, subject us to expenditure of resources with respect to reporting requirements, and limit our ability to contract with non-
U.S. manufacturers.

Some of the licenses or intellectual property rights that we own have been generated through the use of U.S. government funding and may therefore be
subject to certain federal regulations under the Bayh-Dole Act. To the best of our knowledge, our intellectual property for OCU400 for the treatment of
NR2E3 mutation-associated inherited retinal degenerative disease and other inherited retinal degenerative diseases is subject to the Bayh-Dole Act. As a
result, the U.S. government may have certain rights to intellectual property embodied in these patents and patent applications. In general, the Bayh-Dole
Act provides the

79

Table of Contents

U.S.  government  certain  rights  in  inventions  developed  using  a  government  funded  program,  such  as  U.S.  government’s  right  to  a  non-exclusive,  non-
transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, under the Bayh-Dole Act, the U.S. government has
the right to require any invention developed using U.S. government funding to be granted exclusive, partially exclusive, or non-exclusive licenses to any of
these  inventions  to  a  third  party  if  it  determines  that:  (i)  adequate  steps  have  not  been  taken  to  commercialize  the  invention;  (ii)  government  action  is
necessary to meet public health or safety needs; or (iii) government action is necessary to meet requirements for public use under federal regulations (also
referred  to  as  “march-in  rights”).  Under  the  Bayh-Dole  Act,  the  U.S.  government  also  has  the  right  to  take  title  to  inventions  developed  using  a  U.S.
government  funded  program,  if  one  fails  to  disclose  the  invention  to  the  government  and  fails  to  file  an  application  to  register  the  intellectual  property
within specified time limits. In addition, the U.S. government may acquire title to these inventions in any country in which a patent application is not filed
within  specified  time  limits.  Intellectual  property  generated  under  a  government  funded  program  is  also  subject  to  certain  reporting  requirements.  In
addition, the Bayh-Dole Act requires that any products subject to the Bayh-Dole Act be manufactured substantially in the United States. However, under
the Bayh-Dole Act, this manufacturing preference requirement can be waived if the owner of the intellectual property can show that reasonable efforts to
manufacture the product substantially in the United States were unsuccessful, or that under the circumstances, domestic manufacture is not commercially
feasible. Any exercise by the government of any of the foregoing rights under the Bayh-Dole Act may affect our competitive position, business, financial
condition, results of operations, and prospects.

If we fail to comply with our obligations in our intellectual property licenses and funding arrangements with third parties, we could lose rights that are
important to our business.

Our agreements under which we license certain of our patent rights and a significant portion of the technology for our product candidates, impose royalty
and other financial obligations on us and other substantial performance obligations. We may also enter into additional licensing and funding arrangements
with  third  parties  that  may  impose  diligence,  development,  and  commercialization  timelines  and  milestone  payment,  royalty,  insurance,  and  other
obligations on us. If we fail to comply with our obligations under current or future license and collaboration agreements, our counterparties may have the
right  to  terminate  these  agreements,  in  which  event  we  might  not  be  able  to  develop,  manufacture,  or  market  any  product  that  is  covered  by  these
agreements  or  may  face  other  penalties  under  the  agreements.  Such  an  occurrence  could  diminish  the  value  of  our  products  and  product  candidates.
Termination of these agreements or reduction or elimination of our rights under these agreements may result in us having to negotiate new or reinstated
agreements  with  less  favorable  terms  or  cause  us  to  lose  our  rights  under  these  agreements,  including  our  rights  to  important  intellectual  property  or
technology.

In addition, it is possible that our licensors may conclude that we have materially breached the applicable license agreement and might therefore terminate
the agreement, thereby removing our ability to market products covered by such agreements. If any license is terminated, or if the underlying patents fail to
provide the intended market exclusivity, competitors would have the freedom to seek regulatory approval of, and to market, products similar or identical to
ours.  Moreover,  if  any  of  our  license  agreements  are  terminated,  the  counterparty  and/or  its  assignors  may  be  able  to  prevent  us  from  utilizing  the
technology covered by the licensed or assigned patents and patent applications. This could have a materially adverse effect on our competitive business
position and our business prospects.

In addition, the agreements under which we currently license intellectual property or technology from third parties are complex, and certain provisions in
such  agreements  may  be  susceptible  to  multiple  interpretations.  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  candidates,  which
could have a material adverse effect on our business, financial conditions, results of operations, and prospects.

We may not be able to protect our intellectual property and proprietary rights throughout the world.

Filing, prosecuting, and defending patents on product candidates in all countries throughout the world would be prohibitively expensive, and the laws of
foreign countries may not protect our rights to the same extent as the laws of the United States. Consequently, we may not be able to prevent third parties
from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the
United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their
own products and, further, may export otherwise infringing products to territories where we have patent protection or licenses, but

80

Table of Contents

enforcement is not as strong as that in the United States. These products may compete with our products, and our patents or other intellectual property
rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems
of  certain  countries,  particularly  certain  developing  countries,  do  not  favor  the  enforcement  of  patents,  trade  secrets,  and  other  intellectual  property
protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of
competing  products  in  violation  of  our  intellectual  property  and  proprietary  rights  generally.  Proceedings  to  enforce  our  intellectual  property  and
proprietary rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put
our patents at risk of being invalidated or interpreted narrowly, could put our patent applications at risk of not being issued, and could provoke third parties
to  assert  claims  against  us.  We  may  not  prevail  in  any  lawsuits  that  we  initiate,  and  the  damages  or  other  remedies  awarded,  if  any,  may  not  be
commercially meaningful. Accordingly, our efforts to enforce our intellectual property and proprietary rights around the world may be inadequate to obtain
a significant commercial advantage from the intellectual property that we develop or license.

Many  countries  have  compulsory  licensing  laws  under  which  a  patent  owner  may  be  compelled  to  grant  licenses  to  third  parties.  In  addition,  many
countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited
remedies, which could materially diminish the value of such patent. If we or any of our licensors are forced to grant a license to third parties with respect to
any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations, and prospects
may be adversely affected.

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property or claiming ownership
of what we regard as our own intellectual property.

Many of our and our licensors’ employees and contractors were previously employed at other biotechnology, medical device, or pharmaceutical companies,
including our competitors or potential competitors. Although we try to ensure that our employees and contractors do not use the proprietary information or
know-how of others in their work for us, we may be subject to claims that these individuals or we have used or disclosed intellectual property, including
trade secrets or other proprietary information, of any such employee’s former employer. Litigation may be necessary to defend against these claims.

In addition, while it is our policy to require our employees and contractors who may be involved in the development of intellectual property to execute
agreements  assigning  such  intellectual  property  to  us,  we  may  be  unsuccessful  in  executing  such  an  agreement  with  each  party  who  in  fact  develops
intellectual property that we regard as our own. Furthermore, we are unable to control whether our licensors have obtained similar assignment agreements
from their own employees and contractors. Our and their assignment agreements may not be self-executing or may be breached, and we or our licensors
may  be  forced  to  bring  claims  against  third  parties,  or  defend  claims  they  may  bring  against  us,  to  determine  the  ownership  of  what  we  regard  as  our
intellectual property.

If we or our licensors fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property
rights or personnel which could have a material adverse effect on our competitive business position and prospects. Such intellectual property rights could
be awarded to a third party, and we could be required to obtain a license from such third party to commercialize our technology or products, which may not
be available on commercially reasonable terms or at all. Even if we are successful in prosecuting or defending against such claims, litigation could result in
substantial costs and be a distraction to management.

Intellectual property litigation or other legal proceedings relating to intellectual property could cause us to spend substantial resources and distract our
personnel from their normal responsibilities.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses and
could distract our technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results
of hearings, motions, or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have
a substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce
the resources available for development activities or any future sales, marketing, or distribution activities. We may not have sufficient financial or other
resources to conduct such litigation or proceedings adequately. 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 may also have an advantage in such proceedings due to their more mature and
developed intellectual property portfolios. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have
an adverse effect on our ability to compete in the marketplace.

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

In addition to seeking patents for our technology and product candidates, we also rely on trade secrets, including unpatented know-how, technology and
other  proprietary  information,  to  maintain  our  competitive  position.  We  seek  to  protect  these  trade  secrets,  in  part,  by  entering  into  non-disclosure  and
confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators, outside scientific collaborators, contract
manufacturers,  consultants,  advisors,  and  other  third  parties.  We  also  enter  into  confidentiality  and  invention  or  patent  assignment  agreements  with  our
employees and consultants. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our
trade secrets, and we may not be able to obtain adequate remedies for such breaches. Detecting the disclosure or misappropriation of a trade secret and
enforcing  a  claim  that  a  party  illegally  disclosed  or  misappropriated  a  trade  secret  is  difficult,  expensive,  and  time-consuming,  and  the  outcome  is
unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. 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  any  of  our  trade  secrets  were  to  be  disclosed  to  or  independently  developed  by  a
competitor, our competitive position would be harmed.

Risks Related to Our Common Stock

We do not currently intend to pay dividends on our common stock, and, consequently, your ability to achieve a return on your investment will depend
on appreciation, if any, in the price of our common stock.

We have never declared or paid any cash dividend on our common stock. We currently anticipate that we will retain future earnings for the development,
operation, and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. In addition, the terms of
any future debt agreements may preclude us from paying dividends. Any return to stockholders will therefore be limited to the appreciation of their stock.
There is no guarantee that the common stock will appreciate in value or even maintain the price at which stockholders have purchased their shares.

Sales of a substantial number of common stock by our stockholders in the public market could cause our stock price to fall.

If our existing stockholders sell, or indicate an intention to sell, substantial amounts of common stock in the public market, the market price of our common
stock  could  decline.  We  had  221.6  million  shares  of  common  stock  outstanding  as  of  December  31,  2022,  which  were  all  freely  tradable,  without
restriction, in the public market.

If a substantial number of shares of common stock are sold, or if it is perceived that they will be sold, in the public market, the market price of our common
stock could decline and we are unable to predict the effect that sales may have on the prevailing market price of our common stock.

Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to
entrenchment of management.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could significantly reduce the value of our
shares to a potential acquiror or delay or prevent changes in control or changes in our management without the consent of our Board of Directors. The
provisions in our charter documents include the following:

•

•

•

•

•

•

a  classified  Board  of  Directors  with  three-year  staggered  terms,  which  may  delay  the  ability  of  stockholders  to  change  the  membership  of  a
majority of our Board of Directors;

no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;

the  exclusive  right  of  our  Board  of  Directors,  unless  the  Board  of  Directors  grants  such  right  to  the  stockholders,  to  elect  a  director  to  fill  a
vacancy created by the expansion of the Board of Directors or the resignation, death, or removal of a director, which prevents stockholders from
being able to fill vacancies on our Board of Directors;

the prohibition on removal of directors without cause due to the classified Board of Directors;

the ability of our Board of Directors to authorize the issuance of shares of preferred stock and to determine the price and other terms of those
shares,  including  preferences  and  voting  rights,  without  stockholder  approval,  which  could  be  used  to  significantly  dilute  the  ownership  of  a
hostile acquiror;

the ability of our Board of Directors to alter our amended and restated bylaws without obtaining stockholder approval;

the  required  approval  of  at  least  66-2/3%  of  the  shares  entitled  to  vote  to  adopt,  amend,  or  repeal  our  amended  and  restated  bylaws  or  repeal
certain provisions of our amended and restated certificate of incorporation;

a  prohibition  on  stockholder  action  by  written  consent,  which  forces  stockholder  action  to  be  taken  at  an  annual  or  special  meeting  of  our
stockholders;

an exclusive forum provision providing that the Court of Chancery of the State of Delaware will be the exclusive forum for certain actions and
proceedings;

the requirement that a special meeting of stockholders may be called only by the chairman of the Board of Directors, the Chief Executive Officer,
or the Board of Directors, which may delay the ability of our stockholders to force consideration of a proposal or to take action, including the
removal of directors; and

advance notice procedures that stockholders must comply with in order to nominate candidates to our Board of Directors or to propose matters to
be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the
acquiror’s own slate of directors or otherwise attempting to obtain control of us.

We are also subject to the anti-takeover provisions contained in Section 203 of the Delaware General Corporation Law ("DGCL"). Under Section 203, a
corporation may not, in general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock
for three years or, among other exceptions, the board of directors has approved the transaction.

Our sixth amended and restated certificate of incorporation, as amended, provides that the Court of Chancery of the State of Delaware is the exclusive
forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for
disputes with us or our directors, officers, or employees.

Our sixth amended and restated certificate of incorporation, as amended, provides that, unless we consent in writing to the selection of an alternative forum,
the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a
breach of fiduciary duty, any action asserting a claim against us arising pursuant to the DGCL, our amended and restated certificate of incorporation or our
amended and restated bylaws, or any action asserting a claim against us that is governed by the internal affairs doctrine. This exclusive forum provision
would not apply to suits brought to enforce any liability or duty created by the Securities Act of 1933, as amended, or any other claim for which the federal
courts  have  exclusive  jurisdiction.  These  choice  of  forum  provisions  may  limit  a  stockholder’s  ability  to  bring  a  claim  in  a  judicial  forum  that  it  finds
favorable for disputes with us or our directors, officers, or other employees, which may discourage such lawsuits against us and our directors, officers, and
other employees. By agreeing to this provision, however, stockholders will not be deemed to have waived our compliance with the federal securities laws
and  the  rules  and  regulations  thereunder.  Furthermore,  the  enforceability  of  similar  choice  of  forum  provisions  in  other  companies’  certificates  of
incorporation  has  been  challenged  in  legal  proceedings,  and  it  is  possible  that  a  court  could  find  these  types  of  provisions  to  be  inapplicable  or
unenforceable. If a court were to find the choice of forum provisions in our certificate of incorporation to be inapplicable or unenforceable in an action, we
may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

General Risk Factors

The trading price of the shares of our common stock could be highly volatile, and purchasers of our common stock could incur substantial losses.

Our  stock  price  has  been,  and  will  likely  continue  to  be  volatile.  The  stock  market  in  general  and  the  market  for  stock  of  biotechnology  companies  in
particular  have  experienced  extreme  volatility  that  has  often  been  unrelated  to  the  operating  performance  of  particular  companies.  As  a  result  of  this
volatility, investors may not be able to sell their common stock at or above their purchase price. The market price for our common stock may be influenced
by those factors discussed in this "Risk Factors" section and many others, including:

•

•

•

•

our ability to enroll subjects in our ongoing and planned clinical trials;

the results of our clinical trials and preclinical studies, and the results of trials of our competitors or those of other companies in our market sector;

regulatory approval of our product candidates, or limitations to specific label indications or patient populations for use, or changes or delays in the
regulatory review process;

the level of expenses related to any of our product candidates or clinical development programs;

ineffectiveness of our internal control over financial reporting;

additions or departures of key personnel, including major changes in our board or management;

intellectual property, product liability, or other litigation against us; and

general economic, industry, market conditions, and other events or factors, many of which are beyond our control.

In  addition,  in  the  past,  stockholders  have  initiated  class  action  lawsuits  against  biotechnology  companies  following  periods  of  volatility  in  the  market
prices of these companies' stock. Such litigation, including the litigation instituted against us in our current class action lawsuit, could cause us to incur
substantial  costs  and  divert  management's  attention  and  resources,  which  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  and
results of operations.

If securities or industry analysts do not publish research or reports or publish unfavorable research or reports about our business, our stock price and
trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us, our business, our
market, or our competitors. We currently have research coverage by six securities and industry analysts. If one or more of the analysts who currently or in
the future may cover us downgrades our stock, our stock price would likely decline. If one or more of these analysts ceases to cover us or fails to regularly
publish reports on us, interest in our stock could decrease, which could cause our stock price or trading volume to decline.

Our future success depends on our ability to retain key executives and to attract, retain, and motivate qualified personnel.

We  are  highly  dependent  on  the  research  and  development,  clinical,  and  business  development  expertise  of  Shankar  Musunuri,  Ph.D.,  MBA,  our  Chief
Executive  Officer,  Chairman  of  the  Board,  and  Co-Founder,  as  well  as  the  other  principal  members  of  our  management,  scientific,  and  clinical  teams.
Although we have entered into employment agreements with our executive officers, each of them may terminate their employment with us at any time. We
do not maintain "key person" insurance for any of our executives or other employees.

Recruiting and retaining qualified scientific, clinical, manufacturing, legal, financial, and sales and marketing personnel will also be critical to our success.
The  loss  of  the  services  of  our  executive  officers  or  other  key  employees  could  impede  the  achievement  of  our  research,  development,  and
commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing executive officers and
key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of
skills and experience

84

Table of Contents

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  also  experience  competition  for  the  hiring  of  scientific  and  clinical  personnel  from  universities  and
research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and
development  and  commercialization  strategy.  Our  consultants  and  advisors  may  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.

We  expect  to  expand  our  development,  regulatory,  and  manufacturing  capabilities  and  potentially  implement  sales,  marketing,  and  distribution
capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

We expect to experience significant growth in the number of our employees and the scope of our operations, particularly in the areas of drug development,
clinical,  regulatory  affairs,  manufacturing,  sales,  marketing,  and  distribution.  For  example,  we  are  renovating  an  existing  facility  into  a  current  GMP
facility in accordance with the FDA's regulations in support of NeoCart manufacturing for Phase 3 clinical trial material. 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. Our management may need to devote a significant amount of our attention to managing these growth activities. Due to
our limited financial resources and our limited experience in managing such anticipated growth, we may not be able to effectively manage the expansion of
our  operations  or  recruit  and  train  additional  qualified  personnel.  Our  inability  to  manage  the  expansion  of  our  operations  effectively  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. Our expected growth could also require significant capital expenditures and may divert financial resources from other projects, such
as the development of additional product candidates. If we are unable to effectively manage our expected growth, our expenses may increase more than
expected,  our  ability  to  generate  revenues  could  be  reduced,  and  we  may  not  be  able  to  implement  our  business  strategy,  including  the  successful
commercialization of our product candidates.

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

As  a  public  company  we  have  incurred,  and  will  continue  to  incur,  significant  legal,  accounting,  and  other  expenses  that  we  did  not  incur  as  a  private
company. The Sarbanes-Oxley Act of 2002 ("Sarbanes-Oxley"), the Dodd-Frank Wall Street Reform, the Consumer Protection Act, the listing requirements
of  Nasdaq,  and  other  applicable  securities  rules  and  regulations  impose  various  requirements  on  public  companies,  including  establishment  and
maintenance  of  effective  disclosure  and  financial  controls  and  corporate  governance  practices.  We  have  had  to  hire  additional  accounting,  finance,  and
other personnel in connection with our efforts to comply with the requirements of being a public company and our management and other personnel devote
a  substantial  amount  of  time  towards  maintaining  compliance  with  these  requirements.  These  requirements  increase  our  legal  and  financial  compliance
costs and make some activities more time-consuming and costly. These rules and regulations are often subject to varying interpretations, in many cases due
to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing
bodies.  This  could  result  in  continuing  uncertainty  regarding  compliance  matters  and  higher  costs  necessitated  by  ongoing  revisions  to  disclosure  and
governance practices.

In addition, Sarbanes-Oxley, as well as rules subsequently adopted by the SEC and Nasdaq to implement provisions of Sarbanes-Oxley, impose significant
requirements  on  public  companies,  including  requiring  establishment  and  maintenance  of  effective  disclosure  and  financial  controls  and  changes  in
corporate  governance  practices.  Further,  pursuant  to  the  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act  of  2010,  the  SEC  has  adopted
additional rules and regulations in these areas, such as mandatory "say on pay" voting requirements that are applicable to us. Stockholder activism, the
current  political  environment,  and  the  current  high  level  of  government  intervention  and  regulatory  reform  may  lead  to  substantial  new  regulations  and
disclosure  obligations,  which  may  lead  to  additional  compliance  costs  and  impact  the  manner  in  which  we  operate  our  business  in  ways  we  cannot
currently anticipate.

If these requirements divert the attention of our management and personnel from other business concerns, they could have a material adverse effect on our
business, financial condition, and results of operations. The increased costs could impact our results of operations, and may require us to reduce costs in
other areas of our business or increase the prices of our products or services. For example, these rules and regulations make it more difficult and more
expensive for us to obtain director and officer liability insurance. We cannot predict or estimate the amount or timing of additional costs we may incur to
respond to

85

Table of Contents

these requirements. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our Board of
Directors, our board committees, or as executive officers.

If we or any contract manufacturers and suppliers we engage fail to comply with environmental, health, and safety laws and regulations, we could
become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.

We  and  any  contract  manufacturers  and  suppliers  we  engage  are  subject  to  numerous  federal,  state,  and  local  environmental,  health,  and  safety  laws,
regulations, and permitting requirements, including those governing laboratory procedures; the generation, handling, use, storage, treatment, and disposal
of hazardous and regulated materials and wastes; the emission and discharge of hazardous materials into the ground, air, and water; and employee health
and  safety.  Our  operations  involve  the  use  of  hazardous  and  flammable  materials,  including  chemicals  and  biological  materials.  Our  operations  also
produce  hazardous  waste.  We  generally  contract  with  third  parties  for  the  disposal  of  these  materials  and  wastes.  We  cannot  eliminate  the  risk  of
contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable
for any resulting damages, and any liability could exceed our resources. Under certain environmental laws, we could be held responsible for costs relating
to any contamination at our current or past facilities and at third-party facilities. We also could incur significant costs associated with civil or criminal fines
and penalties.

Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental laws and regulations may impair
our research and product development efforts. In addition, we cannot entirely eliminate the risk of accidental injury or contamination from these materials
or  wastes.  Although  we  maintain  workers'  compensation  insurance  to  cover  us  for  costs  and  expenses  we  may  incur  due  to  injuries  to  our  employees
resulting  from  the  use  of  hazardous  materials,  this  insurance  may  not  provide  adequate  coverage  against  potential  liabilities.  We  do  not  carry  specific
biological agents coverage and our commercial general liability policy specifically excludes coverage for damages and fines arising from biological agents.
Accordingly, we could be held liable for damages or be penalized with fines in an amount exceeding our resources, and our clinical trials or regulatory
approvals could be suspended, which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

In addition, we may incur substantial costs in order to comply with current or future environmental, health, and safety laws, regulations, and permitting
requirements. These current or future laws, regulations, and permitting requirements may impair our research, development, or production efforts. Failure
to comply with these laws, regulations, and permitting requirements also may result in substantial fines, penalties, or other sanctions or business disruption,
which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Any  third-party  contract  manufacturers  and  suppliers  we  engage  will  also  be  subject  to  these  and  other  environmental,  health,  and  safety  laws  and
regulations. Liabilities they incur pursuant to these laws and regulations could result in significant costs or an interruption in operations, which could have a
material adverse effect on our business, financial condition, results of operations, and prospects.

If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate and timely financial statements
could be impaired, investors may lose confidence in our financial reporting, and the trading price of our common stock may decline.

Pursuant to Section 404 of Sarbanes-Oxley, our management is required to report upon the effectiveness of our internal control over financial reporting.
The  rules  governing  the  standards  that  must  be  met  for  management  to  assess  our  internal  control  over  financial  reporting  are  complex  and  require
significant  documentation,  testing,  and  possible  remediation.  If  we  are  unable  to  conclude  that  our  internal  control  over  financial  reporting  is  effective,
investors may lose confidence in our financial reporting and the trading price of our common stock may decline.

We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal control over financial reporting in the future. Any
failure  to  maintain  internal  control  over  financial  reporting  could  severely  inhibit  our  ability  to  accurately  report  our  financial  condition,  results  of
operations, or cash flows. If we are unable to conclude that our internal control over financial reporting is effective, investors may lose confidence in the
accuracy  and  completeness  of  our  financial  reports,  the  market  price  of  our  common  stock  could  decline,  and  we  could  be  subject  to  sanctions  or
investigations by Nasdaq, the SEC, or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting,
or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.

We  face  potential  product  liability  exposure,  and  if  successful  claims  are  brought  against  us,  we  may  incur  substantial  liability  for  our  product
candidates and may have to limit our commercialization.

The use of our product candidates in clinical trials, and the sale of any of our product candidates for which we obtain regulatory approval, exposes us to the
risk of product liability claims. Product liability claims might be brought against us by consumers, healthcare providers, pharmaceutical or biotechnology
companies,  or  others  selling  or  otherwise  coming  into  contact  with  our  products.  For  example,  we  may  be  sued  if  any  product  candidate  we  develop
allegedly causes injury or is found to be otherwise unsuitable during clinical testing, manufacturing, marketing, or sale. Any such product liability claims
may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability, or a
breach of warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourself against these claims, we
will incur substantial liabilities or be required to limit development or commercialization of our product candidates. Even successful defense would require
significant financial and management resources. Regardless of merit or eventual outcome, liability claims may result in:

•

•

•

•

•

•

loss of revenue from decreased demand for our products and/or product candidates;

impairment of our business reputation or financial stability;

costs of related litigation;

substantial monetary awards to patients or other claimants;

exhaustion of any available insurance and our capital resources;

diversion of management attention;

• withdrawal of clinical trial participants and potential termination of clinical trial sites or entire clinical programs;

•

•

•

•

•

the inability to commercialize our product candidates;

significant negative media attention;

decrease in our stock price;

initiation of investigations and enforcement actions by regulators; or

product recalls, withdrawals, revocation of approvals, or labeling, marketing, or promotional restrictions.

While we currently hold product liability insurance coverage in an amount that we believe is customary for similarly situated companies, the amount of that
coverage  may  not  be  adequate.  We  may  need  to  increase  our  insurance  coverage  as  we  continue  to  conduct  our  clinical  trials.  We  will  need  to  further
increase our insurance coverage if we commence commercialization of any of our product candidates for which we obtain marketing approval. 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.  On  occasion,  large  judgments  have  been  awarded  in  class  action  lawsuits  based  on  therapeutics  that  had  unanticipated  side  effects.  Our
insurance policies also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. A successful product
liability claim or series of claims brought against us could cause our stock price to fall and, if judgments exceed our insurance coverage, could decrease our
cash and adversely affect our business and our prospects.

Our internal computer systems or those of our development collaborators, third-party CDMOs, or other contractors or consultants may fail or suffer
cybersecurity or other security breaches, which could result in a material disruption of our product development programs and cause our business and
operations to suffer. We face risks related to our collection and use of data, which could result in investigations, inquiries, litigation, fines, legislative
and regulatory action, and negative press about our privacy and data protection practices.

Our internal computer systems and those of our CDMOs and other contractors and consultants are vulnerable to cybersecurity breaches and damage from
computer viruses, unauthorized access, natural disasters, terrorism, war, and telecommunication and electrical failures. While we have not experienced any
such material system failure, accident, or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in
a material disruption of our business operations and product candidate development and, if any of our product candidates are approved, commercialization
programs. Likewise, we intend to rely on third parties to manufacture our product candidates and conduct clinical trials, and similar events relating to their
computer  systems  could  also  have  a  material  adverse  effect  on  our  business  and  operations.  To  the  extent  that  any  disruption  or  cybersecurity  or  other
security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we
could incur liability, the further development and commercialization of our product candidates could be delayed, and our reputation could be harmed. In
addition, there are

87

Table of Contents

known  cyberattacks  against  biotechnology  companies  engaged  in  the  development  of  therapeutic  or  vaccine  products  addressing  COVID-19.  Our
COVAXIN and OCU500 programs could attract the attention of cyberattackers.

Additionally, our business processes personal data, including some data related to health. When conducting clinical trials, we face risks associated with
collecting trial participants' data, especially health data, in a manner consistent with applicable laws and regulations. We also face risks inherent in handling
large  volumes  of  data  and  in  protecting  the  security  of  such  data.  We  could  be  subject  to  attacks  on  our  systems  by  outside  parties  or  fraudulent  or
inappropriate  behavior  by  our  service  providers  or  employees.  Third  parties  may  also  gain  access  to  our  systems  using  stolen  or  inferred  credentials,
computer malware, viruses, spamming, phishing attacks, or other means, and may use such access to obtain personal data. Data breaches could subject us
to  individual  or  consumer  class  action  litigation  and  governmental  investigations  and  proceedings  by  federal,  state,  and  local  regulatory  entities  in  the
United States and by international regulatory entities, resulting in exposure to material civil and/or criminal liability. As our operations and business grow,
we may become subject to or be affected by new or additional data protection laws and regulations and face increased scrutiny or attention from regulatory
authorities,  including  various  domestic  and  international  privacy  and  security  regulations.  The  legislative  and  regulatory  landscape  for  privacy  and  data
protection continues to evolve. In the United States, certain states may adopt privacy and security laws and regulations that may be more stringent than
applicable federal law. For example, California enacted the California Consumer Privacy Act ("CCPA"), which took effect on January 1, 2020. The CCPA
creates  individual  privacy  rights  for  California  consumers  and  increases  the  privacy  and  security  obligations  of  entities  handling  certain  personal  data.
Furthermore, it is anticipated that the California Privacy Rights Act of 2020 ("CPRA"), effective January 1, 2023, will expand the CCPA's requirements,
including applying to personal information of business representatives and employees and establishing a new regulatory agency to implement and enforce
the law.

We may also in the future be subject to data protection laws and regulations of other jurisdictions, such as the EU's General Data Protection Regulation
("GDPR"), which provides data subjects with certain rights and requires organizations to adopt technical and organizational safeguards to protect personal
data.  In  the  event  that  we  are  subject  to  or  affected  by  privacy  and  data  protection  laws,  including  the  CCPA,  CPRA,  or  GDPR  and  other  domestic  or
international privacy and data protection laws, we may expend significant resources to comply with such laws, and any liability from failure to comply with
the requirements of these laws could adversely affect our financial condition.

The increasing use of social media platforms presents new risks and challenges.

Social  media  is  increasingly  being  used  to  communicate  about  our  research,  product  candidates,  and  the  diseases  those  product  candidates  and
investigational  medicines  are  being  developed  to  treat.  Social  media  practices  in  the  biotechnology  industry  and  the  FDA's  regulation  of  social  media
continues  to  evolve.  This  evolution  creates  uncertainty  and  risk  of  noncompliance  with  regulations  applicable  to  our  business,  resulting  in  potential
regulatory  actions  against  us.  For  example,  our  employees  or  agents  may  use  social  media  channels  to  inadvertently  provide  inaccurate  or  misleading
information about our product candidates. If regulators become aware of such disclosures, they may take administrative or enforcement action against us.
There is also a risk that third parties will use social media to disseminate inaccurate or misleading information about us or our product candidates. If this
occurs, we may not be able to adequately defend our business or the public's perception of us or our product candidates, particularly given restrictions on
what we may say about our product candidates prior to FDA approval. If any of these events were to occur or we otherwise fail to comply with applicable
regulations, we could incur liability, face regulatory actions, or incur other harm to our business.

Evolving  expectations  around  corporate  responsibility  practices,  specifically  related  to  environmental,  social  and  governance  ("ESG")  matters,  may
expose us to reputational and other risks.

Investors, stockholders, customers, suppliers and other third parties are increasingly focusing on ESG and corporate social responsibility endeavors and
reporting.  Certain  institutional  investors,  investment  funds,  other  influential  investors,  customers,  suppliers  and  other  third  parties  are  also  increasingly
focused on ESG practices. Companies that do not adapt to or comply with the evolving investor or stakeholder expectations and standards, or which are
perceived to have not responded appropriately, may suffer from reputational damage and result in the business, financial condition, and/or stock price of a
company being materially and adversely affected. Further, this increased focus on ESG issues may result in new regulations and/or third party requirements
that  could  adversely  impact  our  business,  or  certain  shareholders  reducing  or  eliminating  their  holdings  of  our  stock.  Additionally,  an  allegation  or
perception that we have not taken sufficient action in these areas could negatively harm our reputation.

Market Information

Our common stock is traded on the Nasdaq Capital Market under the symbol "OCGN."

Holders

As of February 21, 2023, we had 226.4 million shares of common stock outstanding held by approximately 22 stockholders of record. The actual number
of stockholders is greater than this number of record holders, and includes stockholders who are beneficial owners, but whose shares are held in "street"
name  by  brokers  and  other  nominees.  This  number  of  holders  of  record  also  does  not  include  stockholders  whose  shares  may  be  held  in  trust  by  other
entities.

Dividends

We  have  not  declared  or  paid  any  cash  dividends  on  our  common  stock.  We  currently  anticipate  that  we  will  retain  future  earnings,  if  any,  to  fund  our
operations and do not anticipate declaring or paying any cash dividends for the foreseeable future. As a result, we anticipate that only the appreciation of
the price of our common stock, if any, will provide a return to investors for at least the foreseeable future.

Unregistered Sales of Equity Securities and Use of Proceeds

None.

Issuer Purchases of Equity Securities

During the quarter ended December 31, 2022, we did not repurchase any shares of our common stock.

and uncertainties that could cause our actual results to differ materially from anticipated results. Except as required by law, we undertake no obligation to
publicly update these forward-looking statements, whether as a result of new information, future events, or otherwise. You should read the "Risk Factors"
and "Special Note Regarding Forward-Looking Statements" sections of this Annual Report on Form 10-K for a discussion of important factors that could
cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion
and analysis.

Overview

We are a biotechnology company focused on discovering, developing, and commercializing novel gene and cell therapies and vaccines that improve health
and offer hope for patients across the globe.

Our cutting-edge technology pipeline includes:

• Modifier Gene Therapy Platform — Based on the use of nuclear hormone receptors ("NHRs"), we believe our modifier gene therapy platform
has  the  potential  to  address  many  retinal  diseases,  including  retinitis  pigmentosa  ("RP"),  Leber  congenital  amaurosis  ("LCA"),  dry  age-related
macular degeneration ("AMD"), and Stargardt disease, with a single mutation-agnostic therapy.

• Regenerative  Medicine  Cell  Therapy  Platform  —  Our  Phase  3-ready  regenerative  medicine  cell  therapy  platform  technology,  NeoCart

(autologous chondrocyte-derived neocartilage), is being developed for the repair of knee cartilage injuries in adults.

• Vaccines  —  COVAXIN  is  our  whole-virion  inactivated  intramuscular  COVID-19  vaccine  candidate,  which  we  are  developing  for  the  North
American  market.  We  are  also  developing  a  novel  inhaled  mucosal  vaccine  platform,  which  includes  OCU500,  a  bivalent  COVID-19  vaccine;
OCU510, a seasonal quadrivalent flu vaccine; and OCU520, a combination quadrivalent seasonal flu and bivalent COVID-19 vaccine.

• Novel Biologic Therapy for Retinal Diseases — OCU200 is a novel fusion protein containing parts of human tumstatin and transferrin. OCU200

is designed to treat diabetic macular edema ("DME"), diabetic retinopathy ("DR"), and wet AMD.

Modifier Gene Therapy Platform

We are developing a modifier gene therapy platform designed to fulfill unmet medical needs related to retinal diseases, including inherited retinal diseases
("IRDs"), such as RP, LCA, and Stargardt disease, as well as dry AMD. Our modifier gene therapy platform is based on the use of NHRs, which have the
potential to restore homeostasis — the basic biological processes in the retina. Unlike single-gene replacement therapies, which only target one genetic
mutation,  we  believe  that  our  modifier  gene  therapy  platform,  through  its  use  of  NHRs,  represents  a  novel  approach  that  has  the  potential  to  address
multiple retinal diseases caused by mutations in multiple genes with one product, and potentially address complex diseases that are potentially caused by
imbalances in multiple gene networks.

IRDs,  such  as  RP  and  LCA,  can  lead  to  visual  impairment  and  blindness.  RP  and  LCA  are  associated  with  over  125  mutated  genes  that  affect
approximately  1.6  million  individuals  worldwide.  We  believe  that  OCU400  has  the  potential  to  be  broadly  effective  in  restoring  retinal  integrity  and
function across a range of genetically diverse IRDs, including RP and LCA. OCU400 has received Orphan Drug Designation ("ODD") for nuclear receptor
subfamily 2 group E member 3 ("NR2E3")-related RP and LCA and Orphan Medicinal Product Designation ("OMPD") from the European Commission,
based on the recommendation of the European Medicines Agency, for RP and LCA. We believe these broad ODD and OMPD designations demonstrate
that OCU400 has the potential to be a broad-spectrum therapeutic to treat multiple IRDs. These ODD and OMPD designations represent gene-agnostic
broad coverage for RP and LCA, and are not mutation-specific designations. OCU400 had previously received ODDs from the FDA for the treatment of
the  following  disease  genotypes:  NR2E3,  rhodopsin  ("RHO"),  centrosomal  protein  290  ("CEP290"),  and  phosphodiesterase  6B  mutation-associated
inherited retinal degenerations.

We are conducting a Phase 1/2 clinical trial to assess the safety of unilateral subretinal administration of OCU400 in patients with NR2E3 and RHO-related
RP and CEP290-related LCA in the United States. We have completed dosing patients with RP

91

Table of Contents

in the dose-escalation portion of the clinical trial, which enrolled 10 subjects to receive a low, medium, or high dose of OCU400 in the subretinal space. We
are continuing to enroll subjects with RP and LCA in this clinical trial to receive the high dose, which was determined to be the maximum tolerable dose
from the dose-escalation portion of the clinical trial. We intend to initiate a Phase 1/2 pediatric clinical trial for OCU400 for the treatment of RP and LCA
in the second quarter of 2023 and a Phase 3 clinical trial for OCU400 for the treatment of RP and LCA near the end of 2023, subject to discussions with the
FDA.

We are also developing OCU410 and OCU410ST to utilize the nuclear receptor genes RAR-related orphan receptor A for the treatment of dry AMD and
Stargardt disease, respectively. We are currently executing Investigational New Drug ("IND")-enabling studies and we intend to submit IND applications in
the second quarter of 2023 to initiate Phase 1/2 clinical trials.

Regenerative Medicine Cell Therapy Platform

NeoCart is a Phase 3-ready, regenerative medicine cell therapy technology that combines breakthroughs in bioengineering and cell processing to enhance
the  autologous  cartilage  repair  process.  NeoCart  is  a  three-dimensional  tissue-engineered  disc  of  new  cartilage  that  is  manufactured  by  growing
chondrocytes, the cells responsible for maintaining cartilage health. The chondrocytes are derived from the patient on a unique scaffold. In this therapy,
healthy cartilage tissue is grown and implanted in the patient. We believe NeoCart has the potential to accelerate healing and reduce pain by reconstructing
a patient's previously damaged knee cartilage. It is designed to treat pain at the source, improve function, and potentially prevent a patient's progression to
osteoarthritis. The FDA granted a regenerative medicine advanced therapy designation to NeoCart for the repair of full-thickness lesions of knee cartilage
injuries in adults. We have received concurrence from the FDA on the confirmatory Phase 3 clinical trial design. We are renovating an existing facility into
a current Good Manufacturing Practice facility in accordance with the FDA's regulations in support of NeoCart manufacturing for Phase 3 clinical trial
material. We intend to initiate the Phase 3 clinical trial in the first half of 2024, subject to discussions with the FDA.

Vaccines

Intramuscular COVID-19 Vaccine

We have a Co-Development, Supply and Commercialization Agreement with Bharat Biotech (as amended, the "Covaxin Agreement"), pursuant to which
we obtained an exclusive right and license under certain of Bharat Biotech's intellectual property rights, with the right to grant sublicenses, to develop,
manufacture, and commercialize COVAXIN for the prevention of COVID-19, caused by SARS-CoV-2, in the United States, its territories, and possessions,
Canada,  and  Mexico  (the  "Ocugen  Covaxin  Territory").  COVAXIN  is  a  whole-virion  inactivated,  intramuscular  COVID-19  vaccine  candidate  that  is
manufactured using a Vero cell manufacturing platform. COVAXIN was granted an Emergency Use Listing by the World Health Organization ("WHO") in
November  2021,  has  been  authorized  or  approved  for  use  in  over  25  countries,  and  is  accepted  for  travel  purposes  in  over  85  countries.  Additionally,
COVAXIN has received Emergency Use Authorization ("EUA") in India for children ages six to 18 years. COVAXIN is intended for administration into
the deltoid muscle of the upper arm, in two doses occurring 28 days apart, and has an expected shelf life of 24 months from the date of manufacture at 2-
8°C and a six-month stability at room temperature (25°C).

A Phase 3 clinical trial conducted by Bharat Biotech in India in 25,798 adults, ages 18 years and older, who were healthy or had stable chronic medical
conditions reported an overall estimated vaccine efficacy of COVAXIN against COVID-19 of 77.8%, with efficacy against severe COVID-19 of 93.4%. In
January 2023, we announced top-line results from our Phase 2/3 immuno-bridging and broadening clinical trial in the United States evaluating COVAXIN
for adults ages 18 years and older. The clinical trial was designed to evaluate whether the immune response observed in participants in Bharat Biotech's
Phase  3  clinical  trial  in  India  is  similar  to  a  demographically  representative,  adult  population  in  the  United  States.  The  clinical  trial  enrolled  419  adult
participants that were randomized to receive either two doses of COVAXIN or a placebo, 28 days apart. Immune responses were adjusted for differences
between the U.S. and Indian cohorts in baseline neutralizing antibody, body mass index, gender, and age. Both co-primary immunogenicity endpoints were
met,  with  the  95%  confidence  interval  ("CI")  for  the  propensity  score-adjusted  geometric  mean  titer  ratio  being  well  above  the  non-inferiority  limit  of
0.667. The 95% CI for the propensity score-adjusted difference in seroconversion rates were well above the non-inferiority limit of (10)%. There were no
cases of adverse events and serious adverse events ("SAE") related to the vaccination. 30 medically attended adverse events in 18 subjects and two SAEs in
one subject were reported, all of which were considered unrelated to vaccination. We plan to work with government agencies in the United States to obtain
funding in order to comply with the requirements of a Biologics License Application submission, including funding to initiate an adult safety clinical trial
subject to discussions with the FDA.

In July 2021, we completed our rolling submission to Health Canada for COVAXIN. The rolling submission process, which was conducted through our
Canadian subsidiary, Vaccigen Ltd., was recommended and accepted under the Minister of Health's Interim Order Respecting the Importation, Sale and
Advertising of Drugs for Use in Relation to COVID-19 and transitioned to a

92

Table of Contents

New Drug Submission ("NDS") for COVID-19. In August 2022, we withdrew our NDS based on discussions with Health Canada and are evaluating the
requirements for resubmitting an updated NDS. In Mexico, the Comisión Federal para la Protección contra Riesgos Sanitarios authorized emergency use
for COVAXIN for adults ages 18 years and older, which remains active. We are in discussions with Consejo Nacional de Ciencia y Tecnología in Mexico
regarding our submission for EUA for COVAXIN for pediatric use in ages five to 18 years.

Inhaled Mucosal Vaccines

In September 2022, we entered into an exclusive license agreement ("WU License Agreement") with The Washington University in St. Louis ("Washington
University"),  pursuant  to  which  we  obtained  the  rights  to  develop,  manufacture,  and  commercialize  an  inhaled  mucosal  COVID-19  vaccine  for  the
prevention of COVID-19 in the United States, Europe, and Japan. The WU License Agreement was amended in January 2023 to add the countries of South
Korea, Australia, and China to the territory rights (together with the United States, Europe, and Japan, the "Mucosal Vaccine Territory"). Utilizing these
rights,  we  are  developing  a  novel  inhaled  mucosal  vaccine  platform,  which  includes  OCU500,  a  bivalent  COVID-19  vaccine;  OCU510,  a  seasonal
quadrivalent flu vaccine; and OCU520, a combination quadrivalent seasonal flu and bivalent COVID-19 vaccine. As these vaccine candidates are being
developed to be administered through inhalation, we believe they have the potential to generate rapid local immunity in the upper airways and lungs where
viruses enter and infect the body, which we believe may help reduce or prevent infection and transmission as well as provide protection against new virus
variants. OCU510 is being developed for the global market.

Novel Biologic Therapy for Retinal Diseases

We are developing OCU200, which is a novel fusion protein containing parts of human tumstatin and transferrin. OCU200 is designed to treat DME, DR,
and wet AMD. We have completed the technology transfer of manufacturing processes to our contract development and manufacturing organization and
have produced clinical trial materials to initiate a Phase 1 clinical trial. We submitted an IND application to the FDA in February 2023 to initiate a Phase 1
clinical trial targeting DME.

Financial Operations Overview

We have not generated revenue from our product candidates to date and have incurred net losses in each year since inception. We expect to continue to
incur  net  losses  until  our  product  candidates,  if  approved,  are  successfully  commercialized.  We  incurred  net  losses  of  approximately  $81.4  million  and
$58.4 million for the years ended December 31, 2022 and 2021, respectively. As of December 31, 2022, we had an accumulated deficit of $213.0 million
and a cash, cash equivalents, and investments balance of $90.9 million. Substantially all of our net losses resulted from expenses incurred in connection
with our research and development programs and from general and administrative costs associated with our operations.

Segment Information

As of December 31, 2022, we viewed our operations and managed our business as one operating segment consistent with how our chief operating decision-
maker, our Chief Executive Officer, makes decisions regarding resource allocation and assessing performance. As of December 31, 2022, substantially all
of our assets were located in the United States. Our headquarters are located in Malvern, Pennsylvania.

Research and development expense

Research and development costs are expensed as incurred. These costs consist of internal and external expenses, as well as depreciation expense on assets
used within our research and development activities. Internal expenses include the cost of salaries, benefits, and other related costs, including stock-based
compensation, for personnel serving in our research and development functions, as well as allocated rent and utilities expenses. External expenses include
development,  clinical  trials,  patent  costs,  and  regulatory  compliance  costs  incurred  with  research  organizations,  contract  manufacturers,  and  other  third-
party vendors. License fees paid to acquire access to proprietary technology are expensed to research and development, unless it is determined that the
technology is expected to have an alternative future use. We record costs for certain development activities, such as preclinical studies and clinical trials,
based on our evaluation of the progress to completion of specific tasks. Payments for these activities are based on the terms of the individual arrangements,
which  may  differ  from  the  pattern  of  costs  incurred,  and  are  reflected  in  the  consolidated  financial  statements  as  prepaid  or  accrued  research  and
development expense, as applicable. Our recording of costs for certain development activities requires us to use estimates. We believe our estimates and
assumptions are reasonable under the current conditions; however, actual results may differ from these estimates. Our research and development expenses
are not currently tracked on a program-by-program basis for indirect and overhead costs. We use our

93

Table of Contents

personnel and infrastructure resources across multiple research and development programs directed toward identifying, developing, and commercializing
product candidates.

Research and development expenses account for a significant portion of our operating expenses. We plan to incur research and development expenses for
the foreseeable future as we expect to continue the development of our product candidates. We anticipate that our research and development expenses will
be  higher  in  fiscal  year  2023  as  compared  to  fiscal  year  2022  as  we  continue  to  conduct  preclinical  and  clinical  activities  with  respect  to  our  product
candidates, including the continuation and planned initiation of several clinical trials for our product candidates.

At this time, due to the inherently unpredictable nature of preclinical and clinical developments as well as regulatory approval, we are unable to estimate
with any certainty the costs we will incur and the timelines we will require in our continued development and commercialization efforts. As a result of
these uncertainties, the successful development and completion of clinical trials as well as the regulatory approval process are uncertain and may not result
in approved and commercialized products. Completion dates and completion costs can vary significantly for each product candidate and are difficult to
predict. We will continue to make determinations as to which product candidates to pursue and how much funding to direct to each product candidate on an
ongoing  basis  in  response  to  our  ability  to  enter  into  partnerships  with  respect  to  each  product  candidate  and  the  scientific  and  clinical  success  of  each
product candidate as well as ongoing assessments as to the commercial potential of each product candidate.

General and administrative expense

General  and  administrative  expense  consists  primarily  of  personnel  expenses,  including  salaries,  benefits,  insurance,  and  stock-based  compensation
expense,  for  employees  in  executive,  accounting,  commercialization,  human  resources,  and  other  administrative  functions.  General  and  administrative
expense also includes expenses related to pre-commercial activities, corporate facility costs, such as allocated rent and utilities, insurance premiums, legal
fees related to corporate matters, and fees for auditing, accounting, and other consulting services.

We anticipate that our general and administrative expenses will increase in fiscal year 2023 as compared to fiscal year 2022 as a result of higher corporate
infrastructure costs including, but not limited to accounting, legal, human resources, consulting, investor relations, insurance, and information technology.

Research and development expense increased by $14.6 million for the year ended December 31, 2022 compared to the year ended December 31, 2021. The
increase was primarily due to increases of $13.8 million related to COVAXIN, driven by clinical activities; $6.8 million in employee-related expenses as
we expand our headcount to support our research and development initiatives; $2.9 million related to OCU200 and $1.3 million related to OCU410 and
OCU410ST, both of which are driven by preclinical activities; $1.0 million related to an initial license issuance fee paid to Washington University for the
rights  to  develop,  manufacture,  and  commercialize  an  inhaled  mucosal  COVID-19  vaccine;  and  an  overall  increase  of  $0.2  million  related  to  OCU400,
which is driven by an offsetting increase in clinical activities and decrease in preclinical

94

Table of Contents

activities. These increases are offset by a $15.0 million upfront payment to Bharat Biotech in connection with the amendment to the Covaxin Agreement to
add rights to the Canadian market during the year ended December 31, 2021.

General and administrative expense

General and administrative expense increased by $12.2 million for the year ended December 31, 2022 compared to the year ended December 31, 2021. The
increase  was  primarily  due  to  increases  of  $6.5  million  in  employee-related  expenses,  including  $2.9  million  in  stock-based  compensation  expense;
$3.3  million  in  professional  and  consulting  services,  including  legal  fees;  $1.5  million  in  office  expenses  for  our  new  corporate  headquarters;  and
$1.1 million in pre-commercialization activities. These increases were partially offset by a decrease of $1.9 million in expenses for the annual stockholder
meeting and proxy solicitation.

Other income (expense), net

Other income (expense), net increased by $3.9 million for the year ended December 31, 2022 compared to the year ended December 31, 2021. The increase
was primarily due to $1.4 million in interest earned on our cash, cash equivalents, and investments balance and the collection of $0.8 million related to a
note  receivable  that  was  previously  impaired  during  the  year  ended  December  31,  2021.  These  increases  were  partially  offset  by  a  gain  on  loan
extinguishment of $0.4 million for the forgiveness of the Paycheck Protection Program note during the year ended December 31, 2021.

Liquidity and Capital Resources

As of December 31, 2022, we had $90.9 million in cash, cash equivalents and investments. We have not generated revenue from our product candidates to
date, and have primarily funded our operations to date through the sale of common stock, warrants to purchase common stock, the issuance of convertible
notes  and  debt,  and  grant  proceeds.  Since  our  inception  and  through  December  31,  2022,  we  have  raised  an  aggregate  of  $279.6  million  to  fund  our
operations, of which $266.4 million was from gross proceeds from the sale of our common stock and warrants, $10.3 million was from the issuance of
convertible notes, $2.7 million was from the issuance of debt, and $0.2 million was from grant proceeds.

In June 2022, we entered into an At Market Issuance Sales Agreement ("Sales Agreement") with certain agents, pursuant to which we could, from time to
time, offer and sell shares of our common stock having an aggregate gross sales price of up to $160.0 million. The offer and sale of the shares of common
stock  made  pursuant  to  the  Sales  Agreement  were  made  under  our  Registration  Statement  on  Form  S-3ASR,  which  was  previously  filed  with  the  U.S.
Securities and Exchange Commission and became automatically effective on March 22, 2021, as supplemented by a prospectus supplement, dated June 10,
2022. Pursuant to the Sales Agreement, we sold 9.1 million shares of our common stock and received net proceeds of $13.5 million after deducting equity
issuance costs of $0.6 million. In February 2022, we issued and sold 16.0 million shares of our common stock at a public offering price of $3.13 per share
and received net proceeds of $49.8 million, after deducting equity issuance costs payable by us.

Since our inception, we have devoted substantial resources to research and development and have incurred significant net losses and may continue to incur
net  losses  in  the  future.  We  incurred  net  losses  of  approximately  $81.4  million  and  $58.4  million  for  the  years  ended  December  31,  2022  and  2021,
respectively. As of December 31, 2022, we had an accumulated deficit of $213.0 million. In addition, as of December 31, 2022, we had accounts payable
and accrued expenses and other current liabilities of $18.0 million and indebtedness of $2.3 million.

Operating activities

Cash used in operating activities was $60.1 million for the year ended December 31, 2022 compared to $47.9 million for the year ended December 31,
2021.  The  increase  in  cash  used  in  operating  activities  was  primarily  driven  by  an  increase  in  our  operating  expenses  to  continue  to  support  our
development, commercialization, and business efforts including development and pre-commercialization expenses for our product candidates, employee-
related  expenses,  including  an  increase  in  headcount  to  support  our  operations,  and  professional  and  consulting  services,  including  legal  fees.  These
increases were offset by a $15.0 million upfront payment to Bharat Biotech in connection with the amendment to the Covaxin Agreement to add rights to
the Canadian market in June 2021.

Investing activities

Cash used in investing activities was $17.0 million for the year ended December 31, 2022 compared to $1.8 million for the year ended December 31, 2021.
The increase in cash used in investing activities was primarily driven by purchases of $13.3 million of marketable securities, classified as available-for-sale,
during the year ended December 31, 2022 and an increase of $3.5 million in purchases of property and equipment during the year ended December 31,
2022 as compared to the year ended December 31, 2021. These increases were partially offset by the collection of a note receivable of $0.8 million during
the year ended December 31, 2022 that was issued during the year ended December 31, 2021.

Financing activities

Cash provided by financing activities was $59.5 million for the year ended December 31, 2022 compared to $120.7 million for the year ended December
31, 2021. During the year ended December 31, 2022, cash provided by financing activities primarily consisted of gross proceeds of $50.0 million received
from our underwritten offering that closed in February 2022 and gross proceeds of $8.3 million received from the Sales Agreement. During the year ended
December 31, 2021, cash provided by financing activities primarily consisted of gross proceeds of $122.9 million received under registered direct offerings
and gross proceeds of $5.0 million received under an at-the-market offering, partially offset by payments of equity issuance costs of $8.5 million.

Funding requirements

We  expect  to  continue  to  incur  significant  expenses  in  connection  with  our  ongoing  activities,  particularly  as  we  continue  research  and  development,
including  preclinical  and  clinical  development  of  our  product  candidates,  prepare  to  manufacture  our  product  candidates,  prepare  for  the  potential
commercialization  of  our  product  candidates,  add  operational,  financial,  and  information  systems  to  execute  our  business  plan,  maintain,  expand,  and
protect our patent portfolio, explore strategic licensing, acquisition, and collaboration opportunities to expand our product candidate pipeline to support our
future growth, expand headcount to support our development, commercialization, and business efforts, and operate as a public company.

Factors impacting our future funding requirements include, without limitation, the following:

•

•

•

•

•

•

•

•

•

•

•

the initiation, progress, timing, costs, and results of clinical trials for our product candidates;

the outcome, timing, and cost of the regulatory approval process for our product candidates;

the costs of manufacturing and commercialization;

the costs related to doing business internationally with respect to the development and commercialization of our product candidates;

the cost of filing, prosecuting, defending, and enforcing our patent claims and other intellectual property rights;

the cost of defending intellectual property disputes, including patent infringement actions brought by third parties against us;

the costs of expanding infrastructure to support our development, commercialization, and business efforts, including the costs related to the

the extent to which we out-license our product candidates; and

the impact of geopolitical turmoil, macroeconomic conditions, social unrest, political instability, terrorism, or other acts of war.

As  of  December  31,  2022,  we  had  cash,  cash  equivalents,  and  investments  of  approximately  $90.9  million.  This  amount  will  not  meet  our  capital
requirements  over  the  next  12  months.  We  believe  that  our  cash,  cash  equivalents,  and  investments  will  enable  us  to  fund  our  operations  into  the  first
quarter  of  2024.  Due  to  the  inherent  uncertainty  involved  in  making  estimates  and  the  risks  associated  with  the  research,  development,  and
commercialization of biotechnology products, we may have based this estimate on assumptions that may prove to be wrong, and our operating plan may
change as a result of many factors currently unknown to us. We will need to raise significant additional capital in order to fund our future operations until
we recognize significant revenue from product sales. Our management is currently evaluating different strategies to obtain the required funding for future
operations.  These  strategies  may  include,  but  are  not  limited  to:  public  and  private  placements  of  equity  and/or  debt,  payments  from  potential  strategic
research and development arrangements, sales of assets, government grants, licensing and/or collaboration arrangements with pharmaceutical companies or
other institutions, funding from the government, particularly for the adult safety clinical trial for COVAXIN and for the development of our novel inhaled
mucosal vaccine platform, or funding from other third parties. Our ability to secure funding is subject to numerous risks and uncertainties, including, but
not limited to the impact of the COVID-19 pandemic and geopolitical turmoil, including the ongoing invasion of Ukraine by Russia, and as a result, there
can be no assurance that these funding efforts will be successful. If we cannot obtain the necessary funding, we will need to delay, scale back, or eliminate
some or all of our research and development programs and commercialization efforts; consider other various strategic alternatives, including a merger or
sale; or cease operations. If we cannot expand our operations or otherwise capitalize on our business opportunities because we lack sufficient capital, our
business, financial condition, and results of operations could be materially adversely affected.

As a result of these factors, together with the anticipated increase in spending that will be necessary to continue to research, develop, and commercialize
our  product  candidates,  there  is  substantial  doubt  about  our  ability  to  continue  as  a  going  concern  within  one  year  after  the  date  that  the  consolidated
financial statements included in this Annual Report on Form 10-K are issued.

Off-Balance Sheet Arrangements

We  did  not  have  any  off-balance  sheet  arrangements  during  the  periods  presented,  and  we  do  not  currently  have  any  off-balance  sheet  arrangements  as
defined in the rules and regulations of the SEC.

Critical Accounting Policies and Significant Judgments and Estimates

Our  consolidated  financial  statements  are  prepared  in  accordance  with  generally  accepted  accounting  principles  in  the  United  States  ("GAAP").  The
preparation of our financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, disclosure of
contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of expenses during the reported period. We
base our estimates on historical experience, known trends and events, and various other factors that we believe to be reasonable under the circumstances,
the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.
We  evaluate  our  estimates  and  assumptions  on  an  ongoing  basis.  Our  actual  results  may  differ  from  these  estimates  under  different  assumptions  and
conditions.

While  our  significant  accounting  policies  are  described  in  more  detail  in  the  notes  to  the  consolidated  financial  statements  included  elsewhere  in  this
Annual Report on Form 10-K, we believe that the following accounting policies and estimates are those most critical to the preparation of our consolidated
financial statements:

Research and Development and Clinical Trial Accruals

As  part  of  the  process  of  preparing  the  consolidated  financial  statements  included  elsewhere  in  this  Annual  Report  on  Form  10-K,  we  are  required  to
estimate and record expenses, for which a large portion are research and development expenses. Research and development expenses include, among other
categories,  development,  clinical  trials,  patent  costs,  and  regulatory  compliance  costs  incurred  with  research  organizations,  contract  manufacturers,  and
other  third-party  vendors.  The  estimation  process  involves  identifying  services  that  have  been  performed  on  our  behalf  by  third-parties,  estimating  and
accruing  expenses  in  our  consolidated  financial  statements  based  on  the  evaluation  of  the  progress  to  completion  of  specific  tasks  and  the  facts  and
circumstances known to us at the time of the estimate, and assessing the accuracy of these estimates going forward to determine if adjustments are required.
We periodically collaborate with our third-party vendors to assist in determining our estimates. Payments for these activities performed by our third-party
vendors are based on the terms of the individual arrangements with our third-party vendors, which may differ from the pattern of costs incurred, and are
reflected  in  the  consolidated  financial  statements  as  prepaid  or  accrued  research  and  development  expense,  as  applicable.  We  believe  our  estimates  and
assumptions  are  reasonable  under  the  current  conditions;  however,  actual  results  may  differ  from  these  estimates.  Any  changes  to  estimates  will  be
recorded in the period in which a circumstance causing a change in estimate becomes known and the impact of any change in estimate could be material.

Stock-based compensation

We  account  for  our  stock-based  compensation  awards  in  accordance  with  the  Financial  Accounting  Standards  Board  ("FASB")  Accounting  Standards
Codification  ("ASC")  Topic  718,  Compensation—Stock Compensation  ("ASC  718").  We  have  issued  stock-based  compensation  awards  including  stock
options and restricted stock units ("RSUs"), and we also account for certain issuances of preferred stock and warrants in accordance with ASC 718. ASC
718  requires  all  stock-based  payments,  including  grants  of  stock  options  and  RSUs,  to  be  recognized  in  the  consolidated  statements  of  operations  and
comprehensive loss based on their grant date fair values. We use the Black-Scholes option-pricing model to determine the fair value of options granted. The
fair value of the RSUs is determined by the market price of a share of our common stock on the grant date. We recognize forfeitures as they occur.

Expense related to stock-based compensation awards subject to service-based vesting conditions is recognized on a straight-line basis based on the grant
date fair value over the associated service period of the award, which is generally the vesting term. Stock-based awards generally vest over a one to three
year requisite service period. Stock options have a contractual term of 10 years. To the extent a stock-based compensation award is subject to performance-
based vesting conditions, the amount of expense recorded reflects an assessment of the probability of achieving the performance conditions. Expense for
stock-based compensation awards with performance-based vesting conditions is only recognized when the performance-based vesting condition is deemed
probable to occur. Expense related to stock-based compensation awards are recorded to research and development expense or general and administrative
expense based on the underlying function of the individual that was granted the stock-based compensation award. Shares issued upon stock option exercise
and RSU vesting are newly issued common shares.

Estimating  the  fair  value  of  stock  options  requires  the  input  of  subjective  assumptions,  including  the  expected  term  of  the  stock  option,  stock  price
volatility, the risk-free interest rate, and expected dividends. The assumptions used in our Black-Scholes option-pricing model represent our best estimates
and involve a number of variables, uncertainties, assumptions, and the application of our judgment, as they are inherently subjective. If any assumptions
change, our stock-based compensation expense could be materially different in the future.

The assumptions used in our Black-Scholes option-pricing model for stock options are as follows:

Expected Term. As we do not have sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term, the expected term
of employee options is determined using the "simplified" method, as prescribed in SEC's Staff Accounting Bulletin No. 107, whereby the expected term
equals the arithmetic average of the vesting term and the original contractual term of the option.

Expected Volatility. The expected volatility is based on our historical volatilities and that of similar entities within our industry for periods commensurate
with the assumed expected term.

Risk-Free Interest Rate. The risk-free interest rate is based on the interest rate payable on U.S. Treasury securities in effect at the time of grant for a period
that is commensurate with the assumed expected term.

Expected Dividends.  The  expected  dividend  yield  is  0%  because  we  have  not  historically  paid,  and  do  not  expect  for  the  foreseeable  future  to  pay,  a
dividend on our common stock.

Stock-based compensation expense was $10.5 million and $7.0 million for the years ended December 31, 2022 and 2021, respectively. As of December 31,
2022, we had $14.9 million of unrecognized stock-based compensation expense, which is expected to be recognized over a remaining weighted-average
period of 1.8 years.

Financial Instruments

We evaluate all financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance
with  FASB  ASC  Topic  815,  Derivatives  and  Hedging  ("ASC  815").  Additionally,  we  assess  all  financial  instruments  to  determine  liability  versus
stockholders'  equity  classification  in  accordance  with  ASC  815  and  FASB  ASC  Topic  480,  Distinguishing  Liabilities  from  Equity.  For  derivative
instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value as a derivative liability and is then revalued at
each reporting date, with changes in the fair value reported as other income (expense), net in the consolidated statements of operations and comprehensive
loss. The classification of derivative instruments, including whether such instrument should be recorded as a liability or as stockholders' equity, is evaluated
at the end of each reporting period.

On  March  18,  2021,  we  issued  0.1  million  shares  of  our  Series  B  Convertible  Preferred  Stock,  par  value  $0.01  per  share  (the  "Series  B  Convertible
Preferred  Stock"),  at  a  price  per  share  equal  to  $109.60  to  Bharat  Biotech  under  a  preferred  stock  purchase  agreement  as  an  advance  payment  of
$6.0 million for the supply of COVAXIN. Each share of Series B Convertible Preferred Stock is convertible, at the option of Bharat Biotech, into 10 shares
of our common stock (the "Conversion Ratio") and such conversion is dependent on multiple conversion conditions, including our receipt of shipments by
Bharat Biotech of the first 10.0 million doses of COVAXIN. We accounted for the issuance of the Series B Convertible Preferred Stock in accordance with
ASC  718  as  well  as  determined  that  the  Series  B  Convertible  Preferred  Stock  should  be  classified  as  stockholders'  equity  and  that  the  aforementioned
conversion  option  is  clearly  and  closely  related  to  the  host  contract  and,  as  such,  is  not  an  embedded  derivative  requiring  bifurcation  and  separate
accounting from the host contract. We recorded the fair value of $5.0 million within stockholders' equity during the year ended December 31, 2021, with a
corresponding  short-term  asset  for  the  advanced  payment  for  the  doses  of  COVAXIN.  We  utilized  the  traded  common  stock  price,  adjusted  by  the
Conversion Ratio to value the Series B Convertible Preferred Stock and the Finnerty model to estimate a 15% discount rate for the lack of marketability of
the  instrument.  The  valuation  incorporated  Level  3  inputs  in  the  fair  value  hierarchy,  including  the  estimated  time  until  the  instrument's  liquidity  and
estimated volatility of our common stock as of the grant date. See Note 10 in the notes to the consolidated financial statements included elsewhere in this
Annual Report on Form 10-K for additional information.

Evaluation of Disclosure Controls and Procedures

We  have  carried  out  an  evaluation,  under  the  supervision  and  with  the  participation  of  our  management,  including  our  principal  executive  officer  and
principal 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)  under  the  Securities  Exchange  Act  of  1934,  as  amended  (the  "Exchange  Act"))  as  of  December  31,  2022.  Based  upon  that  evaluation,  our
principal executive officer and principal financial officer concluded that, as of the end of the period covered by this Annual Report on Form 10-K, our
disclosure controls and procedures are effective in ensuring that (a) the information required to be disclosed by us in the reports that we file or submit under
the  Exchange  Act  is  recorded,  processed,  summarized,  and  reported  within  the  time  periods  specified  in  the  SEC's  rules  and  forms,  and  (b)  such
information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate
to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, our management recognized
that  any  controls  and  procedures,  no  matter  how  well  designed  and  operated,  can  provide  only  reasonable  assurance  of  achieving  the  desired  control
objectives,  and  our  management  necessarily  was  required  to  apply  its  judgment  in  evaluating  the  cost-benefit  relationship  of  possible  controls  and
procedures.

Management's Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting
is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, our principal executive officer and
principal  financial  officer  and  effected  by  our  Board  of  Directors,  management,  and  other  personnel,  to  provide  reasonable  assurance  regarding  the
reliability of financial reporting and the preparation of our financial statements for external purposes in accordance with GAAP and includes those policies
and procedures that:

•

•

•

pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with
GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could
have a material effect on our consolidated financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  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.

Under  the  supervision  of  and  with  the  participation  of  our  Chief  Executive  Officer  and  Chief  Accounting  Officer,  our  management  assessed  the
effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2022  based  on  the  criteria  set  forth  by  the  Committee  of  Sponsoring
Organizations of the Treadway Commission in Internal Control-Integrated Framework of 2013. Based on this assessment, management concluded that our
internal control over financial reporting was effective as of December 31, 2022.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Ocugen, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Ocugen,  Inc.  (the  Company)  as  of  December  31,  2022  and  2021,  the  related
consolidated  statements  of  operations  and  comprehensive  loss,  stockholders'  equity  and  cash  flows  for  each  of  the  two  years  in  the  period  ended
December 31, 2022, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial
statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations
and its cash flows for each of the two years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.

The Company's Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in
Note  1  to  the  consolidated  financial  statements,  the  Company  has  suffered  recurring  losses  from  operations  and  has  stated  that  substantial  doubt  exists
about the Company's ability to continue as a going concern. Management's evaluation of the events and conditions and management's plans regarding these
matters  are  also  described  in  Note  1.  The  consolidated  financial  statements  do  not  include  any  adjustments  that  might  result  from  the  outcome  of  this
uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial
statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public  Company  Accounting  Oversight  Board  (United  States)
(PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of
internal  control  over  financial  reporting  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company's  internal  control  over
financial reporting. Accordingly, we express no such opinion.

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in
the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as
evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  financial  statements  that  was  communicated  or
required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2)
involved  our  especially  challenging,  subjective,  or  complex  judgments.  The  communication  of  the  critical  audit  matter  does  not  alter  in  any  way  our
opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate
opinion on the critical audit matter or on the account or disclosure to which it relates.

Description of the
Matter

How We Addressed
the Matter in Our
Audit

Clinical Trial Accrual
As  disclosed  in  Note  8  to  the  consolidated  financial  statements,  the  Company's  clinical  trial  accrual  was  $3.3  million  as  of
December  31,  2022.  The  Company  estimates  the  clinical  trial  accrual  related  to  its  obligations  for  services  performed  on  their
behalf  by  third-party  vendors.  The  amount  recorded  for  the  clinical  trial  accrual  represents  the  Company's  evaluation  of  the
progress to completion of specific tasks and the facts and circumstances known at the time of the estimate as it relates to clinical
trial activities.

Auditing  the  Company's  clinical  trial  accrual  was  complex  due  to  the  estimation  required  by  management  in  determining  the
progress to completion of services that have been performed and will be invoiced by the third-party vendors subsequent to the date
that the consolidated financial statements are issued. The testing of the Company's clinical trial accrual also involves a significant
level of effort to test the high volume of data from third parties.

To test the clinical trial accrual, we performed audit procedures that included, among others, reviewing a sample of agreements
with the third-party vendors to corroborate key financial and contractual terms and testing the completeness and accuracy of the
underlying data used in the computation of the estimate. We also evaluated management's estimates of the progress of completion
for a sample of clinical trial activities by making direct inquiries of the Company's operations personnel that oversee the clinical
trial activities and confirming costs incurred through the balance sheet date directly with the third-party vendors. To evaluate the
completeness of the clinical trial accrual, we examined subsequent invoices and cash disbursements with the third-party vendors,
to the extent such invoices were received or payments were made prior to the date that the consolidated financial statements were
issued.

We have served as the Company's auditor since 2018.

1.    Nature of Business

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

OCUGEN, INC.

Ocugen, Inc., together with its wholly owned subsidiaries ("Ocugen" or the "Company"), is a biotechnology company focused on discovering, developing,
and  commercializing  novel  gene  and  cell  therapies  and  vaccines  that  improve  health  and  offer  hope  for  patients  across  the  globe.  The  Company  is
headquartered in Malvern, Pennsylvania, and manages its business as one operating segment.

Modifier Gene Therapy Platform

The Company is developing a modifier gene therapy platform designed to fulfill unmet medical needs related to retinal diseases, including inherited retinal
diseases  ("IRDs"),  such  as  retinitis  pigmentosa  ("RP"),  Leber  congenital  amaurosis  ("LCA"),  and  Stargardt  disease,  as  well  as  dry  age-related  macular
degeneration ("AMD") with a single mutation-agnostic therapy. The Company's modifier gene therapy platform is based on the use of nuclear hormone
receptors  ("NHRs"),  which  have  the  potential  to  restore  homeostasis  —  the  basic  biological  processes  in  the  retina.  Unlike  single-gene  replacement
therapies, which only target one genetic mutation, the Company believes that its modifier gene therapy platform, through its use of NHRs, represents a
novel approach that has the potential to address multiple retinal diseases caused by mutations in multiple genes with one product, and potentially address
complex diseases that are potentially caused by imbalances in multiple gene networks.

The Company believes that OCU400 has the potential to be broadly effective in restoring retinal integrity and function across a range of genetically diverse
IRDs, including RP and LCA. OCU400 has received Orphan Drug Designation ("ODD") from the United States Food and Drug Administration ("FDA")
for  nuclear  receptor  subfamily  2  group  E  member  3  ("NR2E3")-related  RP  and  LCA  and  Orphan  Medicinal  Product  Designation  ("OMPD")  from  the
European Commission, based on the recommendation of the European Medicines Agency, for RP and LCA. The Company had previously received ODDs
from the FDA for the treatment of certain disease genotypes: NR2E3, centrosomal protein 290 ("CEP290"), rhodopsin ("RHO"), and phosphodiesterase 6B
mutation-associated inherited retinal degenerations.

The Company is conducting a Phase 1/2 clinical trial to assess the safety of unilateral subretinal administration of OCU400 in patients with NR2E3 and
RHO-related RP and CEP290-related LCA in the United States. The Company has completed dosing patients with RP in the dose-escalation portion of the
clinical trial, which enrolled 10 subjects to receive a low, medium, or high dose of OCU400 in the subretinal space. The Company is continuing to enroll
subjects with RP and LCA in this clinical trial to receive the high dose, which was determined to be the maximum tolerable dose from the dose-escalation
portion of the clinical trial. The Company intends to initiate a Phase 1/2 pediatric clinical trial for OCU400 for the treatment of RP and LCA in the second
quarter of 2023 and a Phase 3 clinical trial for OCU400 for the treatment of RP and LCA near the end of 2023, subject to discussions with the FDA.

The Company is also developing OCU410 and OCU410ST to utilize the nuclear receptor genes RAR-related orphan receptor A for the treatment of dry
AMD and Stargardt disease, respectively. The Company is currently executing Investigational New Drug ("IND")-enabling studies and intends to submit
IND applications in the second quarter of 2023 to initiate Phase 1/2 clinical trials.

Regenerative Medicine Cell Therapy Platform

NeoCart is a Phase 3-ready, regenerative medicine cell therapy technology that combines breakthroughs in bioengineering and cell processing to enhance
the  autologous  cartilage  repair  process.  NeoCart  is  a  three-dimensional  tissue-engineered  disc  of  new  cartilage  that  is  manufactured  by  growing
chondrocytes, the cells responsible for maintaining cartilage health. The chondrocytes are derived from the patient on a unique scaffold. In this therapy,
healthy cartilage tissue is grown and implanted in the patient. The Company believes NeoCart has the potential to accelerate healing and reduce pain by
reconstructing a patient's previously damaged knee cartilage. It is designed to treat pain at the source, improve function, and potentially prevent a patient's
progression to osteoarthritis. The FDA granted a regenerative medicine advanced therapy designation to NeoCart for the repair of full-thickness lesions of
knee  cartilage  injuries  in  adults.  The  Company  received  concurrence  from  the  FDA  on  the  confirmatory  Phase  3  clinical  trial  design.  The  Company  is
renovating  an  existing  facility  into  a  current  Good  Manufacturing  Practice  facility  in  accordance  with  the  FDA's  regulations  in  support  of  NeoCart
manufacturing for Phase 3 clinical trial material. The Company intends to initiate the Phase 3 clinical trial in the first half of 2024, subject to discussions
with the FDA.

Vaccines

Intramuscular COVID-19 Vaccine

The  Company  has  a  Co-Development,  Supply  and  Commercialization  Agreement  with  Bharat  Biotech  International  Limited  ("Bharat  Biotech")  (as
amended, the "Covaxin Agreement"), pursuant to which the Company obtained an exclusive right and license under certain of Bharat Biotech's intellectual
property rights, with the right to grant sublicenses, to develop, manufacture, and commercialize COVAXIN for the prevention of COVID-19, caused by
SARS-CoV-2, in the United States, its territories, and possessions, Canada, and Mexico (the "Ocugen Covaxin Territory"). COVAXIN is a whole-virion
inactivated intramuscular COVID-19 vaccine candidate and is formulated with the inactivated SARS-CoV-2 virus, an antigen, and an adjuvant.

In January 2023, the Company announced top-line results from its Phase 2/3 immuno-bridging and broadening clinical trial in the United States evaluating
COVAXIN for adults ages 18 years and older. The clinical trial was designed to evaluate whether the immune response observed in participants in a Phase
3 clinical trial previously conducted by Bharat Biotech in India is similar to a demographically representative, adult population in the United States. The
clinical trial met both co-primary immunogenicity endpoints. There were no cases of adverse events or serious adverse events related to the vaccination
with COVAXIN. The Company plans to work with government agencies in the United States to obtain funding in order to comply with the requirements of
a Biologics License Application submission, including funding to initiate an adult safety clinical trial subject to discussions with the FDA.

In  July  2021,  the  Company  completed  its  rolling  submission  to  Health  Canada  for  COVAXIN.  The  rolling  submission  process,  which  was  conducted
through the Company's Canadian subsidiary, Vaccigen Ltd., was recommended and accepted under the Minister of Health's Interim Order Respecting the
Importation,  Sale  and  Advertising  of  Drugs  for  Use  in  Relation  to  COVID-19  and  transitioned  to  a  New  Drug  Submission  ("NDS")  for  COVID-19.  In
August 2022, the Company withdrew its NDS based on discussions with Health Canada and is evaluating the requirements for resubmitting an updated
NDS. In Mexico, the Comisión Federal para la Protección contra Riesgos Sanitarios authorized emergency use for COVAXIN for adults ages 18 years and
older,  which  remains  active.  The  Company  is  in  discussions  with  Consejo  Nacional  de  Ciencia  y  Tecnología  in  Mexico  regarding  its  submission  for
emergency use authorization for COVAXIN for pediatric use in ages five to 18 years.

Inhaled Mucosal Vaccines

In September 2022, the Company entered into an exclusive license agreement ("WU License Agreement") with The Washington University in St. Louis
("Washington University"), pursuant to which the Company obtained the rights to develop, manufacture, and commercialize an inhaled mucosal COVID-19
vaccine for the prevention of COVID-19 in the United States, Europe, and Japan. The WU License Agreement was amended in January 2023 to add the
countries of South Korea, Australia, and China to the territory rights (together with the United States, Europe, and Japan, the "Mucosal Vaccine Territory").
Utilizing  these  rights,  the  Company  is  developing  a  novel  inhaled  mucosal  vaccine  platform,  which  includes  OCU500,  a  bivalent  COVID-19  vaccine;
OCU510, a seasonal quadrivalent flu vaccine; and OCU520, a combination quadrivalent seasonal flu and bivalent COVID-19 vaccine. As these vaccine
candidates are being developed to be administered through inhalation, the Company believes they have the potential to generate rapid local immunity in the
upper airways and lungs where viruses enter and infect the body, which the Company believes may help reduce or prevent infection and transmission as
well as provide protection against new virus variants. OCU510 is being developed for the global market. The Company intends to initiate IND-enabling
studies and work closely with government agencies to obtain funding for the development of these inhaled mucosal vaccines.

Novel Biologic Therapy for Retinal Diseases

We are developing OCU200, which is a novel fusion protein containing parts of human tumstatin and transferrin. OCU200 is designed to treat diabetic
macular edema ("DME"), diabetic retinopathy ("DR"), and wet AMD. The Company has completed the technology transfer of manufacturing processes to
its  contract  development  and  manufacturing  organization  and  has  produced  clinical  trial  materials  to  initiate  a  Phase  1  clinical  trial.  The  Company
submitted an IND application to the FDA in February 2023 to initiate a Phase 1 clinical trial targeting DME.

Going Concern

The  Company  has  incurred  recurring  net  losses  since  inception  and  has  funded  its  operations  to  date  through  the  sale  of  common  stock,  warrants  to
purchase common stock, the issuance of convertible notes and debt, and grant proceeds. The Company incurred net losses of approximately $81.4 million
and $58.4 million for the years ended December 31, 2022 and

F-10

Table of Contents

2021,  respectively.  As  of  December  31,  2022,  the  Company  had  an  accumulated  deficit  of  $213.0  million  and  cash,  cash  equivalents,  and  investments
totaling $90.9 million. This amount will not meet the Company's capital requirements over the next 12 months. The Company believes that its cash, cash
equivalents, and investments will enable it to fund its operations into the first quarter of 2024. Due to the inherent uncertainty involved in making estimates
and the risks associated with the research, development, and commercialization of biotechnology products, the Company may have based this estimate on
assumptions that may prove to be wrong, and the Company's operating plan may change as a result of many factors currently unknown to the Company.

The Company is subject to risks, expenses, and uncertainties frequently encountered by companies in its industry. The Company intends to continue its
research, development, and commercialization efforts for its product candidates, which will require significant additional funding. If the Company is unable
to obtain additional funding in the future or its research, development, and commercialization efforts require higher than anticipated capital, there may be a
negative impact on the financial viability of the Company. The Company plans to increase working capital through public and private placements of equity
and/or debt, payments from potential strategic research and development arrangements, sales of assets, government grants, licensing and/or collaboration
arrangements  with  pharmaceutical  companies  or  other  institutions,  funding  from  the  government,  particularly  for  the  adult  safety  clinical  trial  for
COVAXIN and for the development of the Company's novel inhaled mucosal vaccine platform, or funding from other third parties. Such financing and
funding may not be available at all, or on terms that are favorable to the Company. While management of the Company believes that it has a plan to fund
ongoing operations, its plan may not be successfully implemented. Failure to generate sufficient cash flows from operations, raise additional capital, or
appropriately  manage  certain  discretionary  spending,  could  have  a  material  adverse  effect  on  the  Company's  ability  to  achieve  its  intended  business
objectives.

As a result of these factors, together with the anticipated increase in spending that will be necessary to continue to research, develop, and commercialize the
Company's product candidates, there is substantial doubt about the Company's ability to continue as a going concern within one year after the date that
these  consolidated  financial  statements  are  issued.  The  consolidated  financial  statements  do  not  contain  any  adjustments  that  might  result  from  the
resolution of any of the above uncertainties.

2.    Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

The accompanying consolidated financial statements included herein have been prepared in conformity with accounting principles generally accepted in the
United  States  ("GAAP")  and  under  the  rules  and  regulations  of  the  U.S.  Securities  and  Exchange  Commission  ("SEC").  The  consolidated  financial
statements  include  the  accounts  of  Ocugen  and  its  wholly  owned  subsidiaries.  All  intercompany  balances  and  transactions  have  been  eliminated  in
consolidation. Certain prior year amounts have been reclassified to conform with current year presentation.

Use of Estimates

In preparing the consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported
amounts of expenses during the reporting period. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods
may  be  affected  by  changes  in  these  estimates.  On  an  ongoing  basis,  the  Company  evaluates  its  estimates  and  assumptions.  These  estimates  and
assumptions include those used in the accounting for research and development contracts, including clinical trial accruals, and the accounting and fair value
measurement of equity instruments.

Segment Information

As of December 31, 2022, the Company viewed its operations and managed its business as one operating segment consistent with how the Company's chief
operating  decision-maker,  the  Company's  Chief  Executive  Officer,  makes  decisions  regarding  resource  allocation  and  assesses  performance.  As  of
December 31, 2022, substantially all of the Company's assets were located in the United States.

Cash, Cash Equivalents, and Restricted Cash

The Company considers all highly liquid investments that have maturities of three months or less when acquired to be cash equivalents. Cash equivalents
may include bank demand deposits and money market funds that invest primarily in certificates of deposit, commercial paper, and U.S. government agency
securities and treasuries. The Company records interest income received on cash and cash equivalents to other income (expense), net in the consolidated
statements  of  operations  and  comprehensive  loss.  The  Company  recorded  $1.4  million  as  interest  income  for  the  year  ended  December  31,  2022.  The
Company's restricted cash balance as of December 31, 2021 consisted of cash held to collateralize a corporate credit card account.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash from the consolidated balance sheets to the total amount shown
in the consolidated statements of cash flows (in thousands):

The  Company  follows  the  provisions  of  Financial  Accounting  Standards  Board  ("FASB")  Accounting  Standards  Codification  ("ASC")  Topic  820,  Fair
Value Measurements ("ASC 820"), which defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit
price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
ASC 820 also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable
inputs when measuring fair value. ASC 820 describes three levels of inputs that may be used to measure fair value:

Level 1 — quoted prices in active markets for identical assets or liabilities

Level 2 — quoted prices for similar assets and liabilities in active markets or inputs that are observable

Level 3 — inputs that are unobservable (for example, cash flow modeling inputs based on assumptions)

The carrying value of certain financial instruments, including cash and cash equivalents, accounts payable, and accrued expenses, approximates their fair
value due to the short-term nature of these instruments.

Marketable Securities

The Company accounts for marketable securities in accordance with FASB ASC Topic 320, Investments - Debt and Equity Securities ("ASC 320"). The
Company  determines  the  appropriate  classification  of  its  investments  in  debt  securities  at  the  time  of  purchase.  Debt  securities  are  classified  as  trading
securities if the security is bought and held primarily to be sold in the near term. Debt securities are classified as held to maturity if management has both
the positive intent and ability to hold until the maturity of the security. All securities not classified as trading securities or held to maturity securities are
classified as available for sale securities. The Company's current marketable securities are comprised of debt securities, including commercial paper, which
are  classified  as  available-for-sale  securities  in  accordance  with  ASC  320.  At  the  time  of  purchase,  the  Company  classifies  marketable  securities  with
maturities of 90 days or less as cash equivalents on the consolidated balance sheets.

Available-for-sale securities are recorded at fair value based on inputs that are observable, either directly or indirectly, such as quoted prices for identical
securities in active markets (Level 1) or quoted prices for similar securities in active markets or inputs that are observable (Level 2). Unrealized gains and
losses are included in other comprehensive income (loss) in the consolidated statements of operations and comprehensive loss. Amortization of premium or
accretion of discount on debt securities are included in other income (expense), net in the consolidated statements of operations and comprehensive loss.

The Company reviews investments in debt securities for other-than-temporary impairment if the fair value of the investment is less than the amortized cost
basis. The assessment for other-than-temporary impairment is performed at the individual security

F-12

Table of Contents

level. The Company did not recognize any impairments with respect to its debt securities during the year ended December 31, 2022. The Company did not
invest in debt securities prior to 2022.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash, cash equivalents, and investments.
The  Company's  cash,  cash  equivalents,  and  investments  are  held  in  accounts  at  financial  institutions  that  may  exceed  federally  insured  limits.  The
Company has not experienced any credit losses in such accounts and does not believe it is exposed to significant credit risk beyond the standard credit risk
associated with commercial banking relationships.

Financial Instruments

The Company evaluates all financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives
in  accordance  with  FASB  ASC  Topic  815,  Derivatives  and  Hedging  ("ASC  815").  Additionally,  the  Company  assesses  all  financial  instruments  to
determine liability versus stockholders' equity classification in accordance with ASC 815 and FASB ASC Topic 480, Distinguishing Liabilities from Equity.
For derivative instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value as a derivative liability and is
then revalued at each reporting date, with changes in the fair value reported as other income (expense), net in the consolidated statements of operations and
comprehensive loss. The classification of derivative instruments, including whether such instrument should be recorded as a liability or as stockholders'
equity, is evaluated at the end of each reporting period.

Property and Equipment, Net

The Company's property and equipment currently includes furniture and fixtures, machinery and equipment, leasehold improvements, and construction in
progress. Property and equipment is recorded at historical cost less accumulated depreciation. Significant additions or improvements are capitalized, and
expenditures for repairs and maintenance are charged to expense as incurred. Depreciation is calculated using the straight-line method and is recognized
over the expected useful life of the underlying asset. Depreciation expense is included as research and development expense or general and administrative
expense  in  the  consolidated  statements  of  operations  and  comprehensive  loss  based  on  the  underlying  nature  of  the  associated  asset.  Construction  in
progress is not depreciated until such time that the asset is completed and placed into service. The Company's construction in progress as of December 31,
2022 related to the renovation of one of the Company's leased properties to develop a laboratory and manufacturing facility and the equipment that will be
utilized in the laboratory and manufacturing facility that has not yet been placed into service. Once placed into service, this equipment will be depreciated
over its expected useful life.

Expected useful lives by major asset category are as follows:

Furniture and fixtures
Machinery and equipment
Leasehold improvements

Leases

3 to 7 years
5 to 7 years
Shorter of the expected useful life or remaining lease term

The  Company  determines  if  an  arrangement  is  a  lease  at  inception.  This  determination  generally  depends  on  whether  the  arrangement  conveys  to  the
Company the right to control the use of an explicitly or implicitly identified fixed asset for a period of time in exchange for consideration. Control of an
underlying asset is conveyed to the Company, if the Company obtains the rights to direct the use of and to obtain substantially all of the economic benefits
from using the underlying asset. The Company's lease agreements include lease and non-lease components, which the Company has elected not to account
for separately for all classes of underlying assets. Lease expense for variable lease components is recognized when the obligation is probable.

The Company currently leases real estate classified as operating leases. Operating leases are included in other assets and operating lease obligations in the
Company's consolidated balance sheets. At lease commencement, the Company records a lease liability based on the present value of the lease payments
over the expected lease term including any options to extend the lease that the Company is reasonably certain to exercise and records a corresponding right-
of-use lease asset based on the lease liability, adjusted for any lease incentives received and any initial direct costs paid to the lessor prior to the lease

F-13

Table of Contents

commencement  date.  Lease  expense  is  recognized  on  a  straight-line  basis  over  the  lease  term  and  recognized  as  research  and  development  expense  or
general and administrative expense based on the underlying nature of the expense. FASB ASC Topic 842, Leases ("ASC 842") requires a lessee to discount
its  unpaid  lease  payments  using  the  interest  rate  implicit  in  the  lease  or,  if  that  rate  cannot  be  readily  determined,  its  incremental  borrowing  rate.  The
implicit interest rates were not readily determinable in the Company's current operating leases. As such, the incremental borrowing rates were used based
on the information available at the commencement dates in determining the present value of lease payments.

The lease term for the Company's leases includes the non-cancellable period of the lease plus any additional periods covered by either an option to extend
(or not to terminate) the lease that the Company is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the
lessor.

Lease payments included in the measurement of the lease liability are comprised of fixed payments, variable payments that depend on an index or rate, and
amounts probable to be payable under the exercise of an option to purchase the underlying asset if reasonably certain.

Variable  payments  not  dependent  on  an  index  or  rate  associated  with  the  Company's  leases  are  recognized  when  the  event,  activity,  or  circumstance  is
probable.  Variable  payments  include  the  Company's  proportionate  share  of  certain  utilities  and  other  operating  expenses  and  are  presented  as  operating
expenses  in  the  Company's  consolidated  statements  of  operations  and  comprehensive  loss  in  the  same  line  item  as  expense  arising  from  fixed  lease
payments.

Impairment of Assets

The Company reviews its assets, including property and equipment, for impairment whenever changes in circumstances or events may indicate that the
carrying amounts are not recoverable. These indicators include, but are not limited to, a significant change in the extent or manner in which an asset is used
or its physical condition, a significant decrease in the market price of an asset, or a significant adverse change in the business or the industry that could
affect the value of an asset. An asset is tested for impairment by comparing the net carrying value of the asset to the undiscounted net cash flows to be
generated from the use and eventual disposition of the asset.

Stock-Based Compensation

The Company accounts for its stock-based compensation awards in accordance with FASB ASC Topic 718, Compensation—Stock Compensation ("ASC
718").  The  Company  has  issued  stock-based  compensation  awards  including  stock  options  and  restricted  stock  units  ("RSUs"),  and  also  accounts  for
certain  issuances  of  preferred  stock  and  warrants  in  accordance  with  ASC  718.  ASC  718  requires  all  stock-based  payments,  including  grants  of  stock
options  and  RSUs,  to  be  recognized  in  the  consolidated  statements  of  operations  and  comprehensive  loss  based  on  their  grant  date  fair  values.  The
Company  uses  the  Black-Scholes  option-pricing  model  to  determine  the  fair  value  of  stock  options  granted.  For  RSUs,  the  fair  value  of  the  RSU  is
determined by the market price of a share of the Company's common stock on the grant date. The Company recognizes forfeitures as they occur.

Expense related to stock-based compensation awards granted with service-based vesting conditions is recognized on a straight-line basis based on the grant
date fair value over the associated service period of the award, which is generally the vesting term. Stock-based compensation awards generally vest over a
one  to  three  year  requisite  service  period.  Stock  options  have  a  contractual  term  of  10  years.  Expense  for  stock-based  compensation  awards  with
performance-based vesting conditions is only recognized when the performance-based vesting condition is deemed probable to occur. Expense related to
stock-based  compensation  awards  are  recorded  to  research  and  development  expense  or  general  and  administrative  expense  based  on  the  underlying
function of the individual that was granted the stock-based compensation award. Shares issued upon stock option exercise and RSU vesting are newly-
issued common shares.

Estimating  the  fair  value  of  stock  options  requires  the  input  of  subjective  assumptions,  including  the  expected  term  of  the  stock  option,  stock  price
volatility,  the  risk-free  interest  rate,  and  expected  dividends.  The  assumptions  used  in  the  Company's  Black-Scholes  option-pricing  model  represent
management's  best  estimates  and  involve  a  number  of  variables,  uncertainties,  assumptions,  and  the  application  of  management's  judgment,  as  they  are
inherently subjective. If any assumptions change, the Company's stock-based compensation expense could be materially different in the future.

The assumptions used in Ocugen's Black-Scholes option-pricing model for stock options are as follows:

Expected  Term.  As  Ocugen  does  not  have  sufficient  historical  exercise  data  to  provide  a  reasonable  basis  upon  which  to  estimate  expected  term,  the
expected term of employee stock options subject to service-based vesting conditions is determined

F-14

Table of Contents

using the "simplified" method, as prescribed in SEC's Staff Accounting Bulletin No. 107, whereby the expected term equals the arithmetic average of the
vesting term and the original contractual term of the stock option.

Expected  Volatility.  The  expected  volatility  is  based  on  historical  volatilities  of  Ocugen  and  similar  entities  within  Ocugen's  industry  for  periods
commensurate with the assumed expected term.

Risk-Free Interest Rate. The risk-free interest rate is based on the interest rate payable on U.S. Treasury securities in effect at the time of grant for a period
that is commensurate with the assumed expected term.

Expected Dividends. The expected dividend yield is 0% because Ocugen has not historically paid, and does not expect for the foreseeable future to pay, a
dividend on its common stock.

Collaboration Arrangements

The  Company  assesses  whether  collaboration  agreements  are  subject  to  FASB  ASC  Topic  808,  Collaborative  Arrangements  ("ASC  808"),  based  on
whether they involve joint operating activities and whether both parties have active participation in the arrangement and are exposed to significant risks and
rewards. To the extent that the arrangement falls within the scope of ASC 808, the Company assesses whether the transactions between the Company and
the  collaboration  partner  are  subject  to  other  accounting  literature.  If  transactions  with  a  collaboration  partner  are  reflective  of  a  vendor-customer
relationship, the Company accounts for those payments within the scope of FASB ASC Topic 606, Revenue from Contracts with Customers. However, if
the  Company  concludes  that  its  collaboration  partner  is  not  a  customer,  the  Company  will  record  transactions  with  the  collaboration  partner  under  an
appropriate  recognition  method  that  is  determined  and  applied  consistently  either  by  analogy  to  appropriate  accounting  literature  or  be  applying  a
reasonable accounting policy election. Classification of such transactions in the consolidated statements of operations and comprehensive loss is based on
the nature of the transaction.

Income Taxes

The Company uses the asset and liability method in accounting for income taxes. Deferred tax assets and liabilities are recorded for temporary differences
between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements, using statutory tax rates in effect for the
year  in  which  the  differences  are  expected  to  reverse.  The  effect  on  deferred  tax  assets  and  liabilities  of  a  change  in  tax  rates  is  recognized  in  the
consolidated statements of operations and comprehensive loss in the period that includes the enactment date.

The Company evaluates its deferred tax assets each period to ensure that the estimated future taxable income will be sufficient in character, amount, and
timing, to result in its realizability. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets, unless it is more likely than not
that those assets will be realized. Management utilizes considerable judgment when establishing deferred tax valuation allowances. The ultimate realization
of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences and carryforward
deferred tax assets become deductible or utilized. The Company considers the scheduled reversal of taxable temporary differences, projected future taxable
income,  and  tax  planning  strategies  in  making  this  assessment.  As  events  and  circumstances  change,  valuation  allowances  are  adjusted  within  the
consolidated statement of operations and comprehensive loss when applicable.

The  Company  recognizes  net  tax  benefits  under  the  recognition  and  measurement  criteria  of  FASB  ASC  Topic  740,  Income  Taxes,  which  prescribes
requirements  and  other  guidance  for  financial  statement  recognition  and  measurement  of  positions  taken  or  expected  to  be  taken  on  tax  returns.  The
Company recognizes a tax benefit for positions taken for tax return purposes when it will be more likely than not that the positions will be sustained upon
tax examination, based solely on the technical merits of the tax positions. Otherwise, no tax benefit is recognized. The tax benefits recognized are measured
based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes potential accrued
interest  and  penalties  related  to  unrecognized  tax  benefits  as  a  component  of  income  tax  expense  in  the  consolidated  statement  of  operations  and
comprehensive loss. Tax examinations are often complex, as tax authorities may disagree with the treatment of items reported by the Company and may
require  several  years  to  resolve.  As  a  result,  the  Company's  provision  for  income  taxes  is  recorded  on  the  basis  of  available  information,  but  amounts
recorded may be impacted as a result of future examinations.

Recently Adopted Accounting Standards

In November 2021, the FASB issued Accounting Standards Update ("ASU") No. 2021-10, Government Assistance (Topic 832): Disclosures by Business
Entities about Government Assistance. This standard increases the transparency of transactions with the government that are accounted for by applying a
grant or contribution accounting model, and aims to reduce diversity that

F-15

Table of Contents

currently  exists  in  the  recognition,  measurement,  presentation,  and  disclosure  of  government  assistance  received  by  business  entities  due  to  the  lack  of
specific authoritative guidance in GAAP. This standard requires an entity to provide information regarding the nature of the transaction with a government
and  the  related  accounting  policy  used  to  account  for  this  transaction,  the  line  items  on  the  consolidated  balance  sheet  and  consolidated  statement  of
operations and comprehensive loss that are affected by the transaction and the amounts applicable to each financial statement line item, and the significant
terms and conditions of the transaction, including commitments and contingencies. The standard was effective for the Company on January 1, 2022. The
adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In  May  2021,  the  FASB  issued  ASU  No.  2021-04,  Earnings  Per  Share  (Topic  260),  Debt  —  Modifications  and  Extinguishments  (Subtopic  470-50),
Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40).  This  standard
clarifies  and  reduces  diversity  in  an  issuer's  accounting  for  modifications  or  exchanges  of  freestanding  equity-classified  written  call  options,  including
warrants,  that  remain  equity-classified  after  the  modification  or  exchange.  The  standard  requires  an  entity  to  treat  a  modification  or  an  exchange  of  a
freestanding equity-classified written call option that remains equity-classified after the modification or exchange as an exchange of the original instrument
for a new instrument. The standard additionally provides guidance on measuring and recognizing the effect of a modification or an exchange. The standard
was effective for the Company on January 1, 2022. The adoption of this standard did not have a material impact on the Company's consolidated financial
statements.

Recent Accounting Pronouncements

In August 2020, the FASB issued ASU No. 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging —
Contracts in Entity's Own Equity (Subtopic 815-40). This standard will have an effective and transition date of January 1, 2024. Early adoption is currently
permitted.  This  standard  simplifies  an  issuer's  accounting  for  convertible  instruments  by  eliminating  two  of  the  three  models  that  require  separate
accounting for embedded conversion features as well as simplifies the settlement assessment that entities are required to perform to determine whether a
contract qualifies for equity classification. This standard also requires entities to use the if-converted method for all convertible instruments in the diluted
earnings per share calculation and include the effect of potential share settlement (if the effect is more dilutive) for instruments that may be settled in cash
or  shares,  except  for  certain  liability-classified  share-based  payment  awards.  The  standard  requires  new  disclosures  about  events  that  occur  during  the
reporting period and cause conversion contingencies to be met and about the fair value of a public business entity's convertible debt at the instrument level,
among  other  things.  The  Company  does  not  currently  expect  the  adoption  of  this  standard  to  have  a  material  impact  on  the  Company's  consolidated
financial statements.

In  June  2016,  the  FASB  issued  ASU  No.  2016-13,  Financial  Instruments  —  Credit  Losses  (Topic  326):  Measurement  of  Credit  Losses  on  Financial
Instruments. The FASB subsequently issued amendments to ASU No. 2016-13, which have the same effective date and transition date of January 1, 2023.
ASU No. 2016-13, as amended, requires that credit losses be reported using an expected losses model rather than the incurred losses model that is currently
used, and establishes additional disclosures related to credit risks. For available-for-sale debt securities with unrealized losses, these standards now require
allowances to be recorded instead of reducing the amortized cost of the investment. These standards limit the amount of credit losses to be recognized for
available-for-sale debt securities to the amount by which carrying value exceeds fair value and requires the reversal of previously recognized credit losses if
fair  value  increases.  The  Company  does  not  currently  expect  the  adoption  of  this  standard  to  have  a  material  impact  on  the  Company's  consolidated
financial statements.

3.    License and Development Agreements

Co-Development and Commercialization Agreement with CanSino Biologics, Inc.

The  Company  entered  into  a  co-development  and  commercialization  agreement  with  CanSino  Biologics,  Inc.  ("CanSinoBIO")  with  respect  to  the
development  and  commercialization  of  the  Company's  modifier  gene  therapy  product  candidates,  OCU400,  OCU410,  and  OCU410ST.  The  co-
development and commercialization agreement was originally entered into in September 2019 with regards to OCU400, and was subsequently amended in
September 2021 and November 2022 (as so amended, the "CanSinoBIO Agreement"), to include OCU410 and OCU410ST, respectively, to the Company's

In September 2022, the Company entered into the WU License Agreement with Washington University, pursuant to which the Company was granted an
exclusive, sublicensable, royalty-bearing license to patent rights for an inhaled mucosal COVID-19 vaccine, as well as a license to certain tangible research
property  and  technical  information  necessary  to  exploit  the  patent  rights  within  the  United  States,  Europe,  and  Japan.  The  Company  paid  Washington
University  an  initial  license  issuance  fee  of  $1.0  million,  which  was  recognized  as  research  and  development  expense  in  the  consolidated  statement  of
operations and comprehensive loss during the year ended December 31, 2022. In January 2023, the Company amended the WU License Agreement to add
the countries of South Korea, Australia, and China to the Mucosal Vaccine Territory. The Company is required to pay Washington University an annual
license  maintenance  fee,  payments  upon  the  achievement  of  certain  development  and  commercial  milestones  in  the  aggregate  amount  of  up  to  $37.0
million, and low single-digit percentage royalties on Net Sales of licensed products (as defined in the WU License Agreement).

Pursuant  to  the  WU  License  Agreement,  the  Company  may  make,  have  made,  sell,  offer  for  sale,  use,  market,  promote,  distribute,  export,  and  import
licensed products in the Mucosal Vaccine Territory. The Company will use commercially reasonable efforts to develop, manufacture, promote, and sell the
licensed products in the Mucosal Vaccine Territory.

Washington  University  maintains  control  of  patent  preparation,  filing,  prosecution,  and  maintenance.  The  Company  is  responsible  for  Washington
University's out-of-pocket expenses related to the preparation, filing, prosecution, issuance, and maintenance of the licensed patent rights incurred pursuant
to the WU License Agreement.

The WU License Agreement will expire on a country-by-country basis and a licensed product-by-licensed product basis and end, separately in each such
country and for each such licensed product, upon the latter of (a) the expiration date of the last valid claim, (b) the fifteenth (15th) anniversary of the date of
the  first  commercial  sale  of  a  licensed  product,  or  (c)  the  expiration  of  the  last  form  of  market  exclusivity  (as  defined  in  the  WU  License  Agreement),
subject to the earlier termination of the WU License Agreement in accordance with its terms. In addition, the Company may terminate the WU License
Agreement without cause by giving at least 90 days written notice. The WU License Agreement contains customary termination provisions in the event of
an uncured material breach or upon certain corporate actions, including bankruptcy, receivership, or liquidation.

Co-Development, Supply and Commercialization Agreement with Bharat Biotech

The  Company  entered  into  the  Covaxin  Agreement  with  Bharat  Biotech  to  co-develop  COVAXIN  for  the  Ocugen  Covaxin  Territory.  The  Covaxin
Agreement was originally entered into in February 2021 with respect to the U.S. market and was subsequently amended in June 2021 to add rights to the
Canadian market, for which the Company paid Bharat Biotech a non-refundable, upfront payment of $15.0 million in June 2021, which was recognized as
research and development expense in the consolidated statements of operations and comprehensive loss during the year ended December 31, 2021. The
Company additionally agreed to pay Bharat Biotech $10.0 million within 30 days after the first commercial sale of COVAXIN in Canada. The Covaxin
Agreement was amended a second time in April 2022 to add rights to the Mexican market. The Covaxin Agreement is a collaborative arrangement within
the scope of ASC 808.

Pursuant to the Covaxin Agreement, the Company obtained an exclusive right and license under certain of Bharat Biotech's intellectual property rights,
with the right to grant sublicenses, to develop, manufacture, and commercialize COVAXIN in the

F-17

Table of Contents

Ocugen  Covaxin  Territory.  In  consideration  of  the  license  and  other  rights  granted  to  the  Company  by  Bharat  Biotech,  the  parties  agreed  to  share  any
operating profits (as defined in the Covaxin Agreement) generated from the commercialization of COVAXIN in the Ocugen Covaxin Territory, with the
Company retaining 45% of such profits, and Bharat Biotech receiving the balance of such profits.

Under the Covaxin Agreement, the Company is collaborating with Bharat Biotech to develop COVAXIN for their respective territories. Except with respect
to  manufacturing  rights  under  certain  circumstances  as  described  below,  the  Company  has  the  exclusive  right  and  is  solely  responsible  for  researching,
developing, manufacturing, and commercializing COVAXIN for the Ocugen Covaxin Territory. Bharat Biotech is responsible for researching, developing,
manufacturing, and commercializing COVAXIN outside of the Ocugen Covaxin Territory. Bharat Biotech agreed to provide to the Company preclinical
and clinical data, and to transfer to the Company certain proprietary technology owned or controlled by Bharat Biotech, that is necessary for the successful
commercial manufacture and supply of COVAXIN to support potential commercial sale in the Ocugen Covaxin Territory.

In  September  2021,  the  Company  entered  into  a  Development  and  Commercial  Supply  Agreement  (the  "Supply  Agreement")  with  Bharat  Biotech,
pursuant to which Bharat Biotech will supply the Company with clinical trial materials and commercial supplies of COVAXIN finished drug product prior
to  the  completion  of  a  technology  transfer.  Following  the  completion  of  a  technology  transfer,  Bharat  Biotech  will  supply  COVAXIN  drug  product
components  and  continue  to  supply  finished  drug  product  as  necessary  for  the  commercial  manufacture  and  supply  of  COVAXIN.  In  March  2021,  the
Company issued shares of Series B Convertible Preferred Stock (as defined in Note 10) as an advance payment for the supply of COVAXIN to be provided
by Bharat Biotech under the Supply Agreement. See Note 10 for additional information about the Series B Convertible Preferred Stock issuance to Bharat
Biotech.

The  Covaxin  Agreement  continues  in  effect  for  the  commercial  life  of  COVAXIN,  subject  to  the  earlier  termination  of  the  Covaxin  Agreement  in
accordance with its terms. The Covaxin Agreement also contains customary representations and warranties made by the Company and Bharat Biotech and
customary  provisions  relating  to  indemnification,  limitation  of  liability,  confidentiality,  information  and  data  sharing,  and  other  matters.  The  Supply
Agreement expires upon the expiration of the Covaxin Agreement and may be earlier terminated by the Company or Bharat Biotech in the event of an
uncured material breach or bankruptcy of the other party.

Exclusive License Agreement with The Schepens Eye Research Institute, Inc.

In  December  2017,  the  Company  entered  into  an  exclusive  license  agreement  with  The  Schepens  Eye  Research  Institute,  Inc.  ("SERI"),  which  was
amended  in  January  2021  (as  so  amended,  the  "SERI  Agreement").  The  SERI  Agreement  gives  the  Company  an  exclusive,  worldwide,  sublicensable
license  to  patent  rights,  biological  materials,  and  technical  information  for  NHR  genes  Nuclear  Receptor  Subfamily  1  Group  D  Member  1  ("NR1D1"),
NR2E3 (OCU400), RORA (OCU410 and OCU410ST), Nuclear Protein 1, Transcriptional Regulator ("NUPR1"), and Nuclear Receptor Subfamily 2 Group
C Member 1 ("NR2C1"). The January 2021 amendment to the SERI Agreement additionally granted the Company rights in co-owned intellectual property
pursuant to certain patents and provisional patents at the time of the amendment. Under the SERI Agreement, the Company may make, have made, use,
offer to sell, sell, and import licensed products, and must use commercially reasonable efforts to bring one or more licensed products to market as soon as
reasonably practicable.

The  SERI  Agreement  requires  the  Company  to  pay  licensing  fees  for  patent  rights  granted,  an  annual  license  maintenance  fee,  payment  of  certain
development and commercial milestones in the aggregate amount of $16.1 million, and low single-digit percentage royalties on annual net sales of products
that fall under the licensed patent rights. The SERI Agreement is a collaborative arrangement within the scope of ASC 808.

SERI maintains control of patent preparation, filing, prosecution, and maintenance. The Company is responsible for SERI's out-of-pocket expenses related
to the filing, prosecution, and maintenance of the licensed patent rights. In the event that SERI decides to discontinue the prosecution or maintenance of the
licensed  patent  rights,  the  Company  has  the  right,  but  not  the  obligation,  to  file  for,  or  continue  to  prosecute,  maintain,  or  enforce  such  licensed  patent
rights. The Company has assumed prosecution of certain licensed patent rights under the SERI Agreement.

The SERI Agreement will expire on the expiration date of the last to expire licensed patent rights, subject to the earlier termination of the SERI Agreement
in  accordance  with  its  terms.  The  Company  may  terminate  the  license  upon  180  days  prior  written  notice.  SERI  may  immediately  terminate  the  SERI
Agreement if the Company ceases to carry on its business with respect to the licensed patent rights, fails to make payments within thirty days of receiving a
written notice of missed payment, fails to comply with its diligence obligations, defaults on its obligation to procure and maintain insurance, one of its
officers is

convicted of a felony related to the licensed products, the Company breaches any material obligation of the agreement and does not cure such breach within
90 days, or if the Company becomes bankrupt or insolvent.

Exclusive License Agreement with the University of Colorado

In March 2014, the Company entered into an exclusive license agreement with the University of Colorado ("CU"), which was amended in January 2017
and clarified by a letter of understanding in November 2017 (as so amended and clarified, the "CU Agreement"). The CU Agreement gives the Company
an  exclusive,  worldwide,  sublicensable  license  to  patents  for  OCU200  to  make,  have  made,  use,  import,  offer  to  sell,  sell,  have  sold,  and  practice  the
licensed  products  in  all  therapeutic  applications.  Under  the  CU  Agreement,  the  Company  must  use  commercially  reasonable  efforts  to  develop,
manufacture, sublicense, market, and sell the licensed products, and has assumed primary responsibility for preparing, filing, and prosecuting broad patent
claims for OCU200 for CU's benefit. Further, the Company assumed primary responsibility for all patent activities, including all costs associated with the
perfection and maintenance of the patents for OCU200.

The CU Agreement requires the payment for certain regulatory milestones aggregating to $1.5 million, an annual minimum payment that began the third
year after the effective date, low single-digit percentage earned royalties on net sales, and royalties in the mid-teens on sublicense income of OCU200. The
Company has made no milestone or royalty payments to date pursuant to the CU Agreement.

The CU Agreement will expire on the latter of the expiration date of the last to expire licensed patent or the end of any relevant statutory or regulatory
exclusivity period. The Company may terminate the CU Agreement upon 60 days prior written notice. CU may terminate the CU Agreement upon 60 days
notice if the Company fails to make payments within 60 days of such payment's due date, breaches and does not cure any diligence obligation, provides any
materially false report, or otherwise materially breaches and does not cure any material provision of the CU Agreement.

License Agreement with Purpose Co. Ltd.

In  December  2005,  Histogenics  Corporation  ("Histogenics")  entered  into  an  exclusive  agreement  (the  "Purpose  Agreement")  to  sublicense  certain
technology from Purpose Co. Ltd. ("Purpose"), which the Company assumed as a result of its reverse merger with Histogenics. Purpose entered into the
original  license  agreement  ("BWH-Purpose  Agreement")  with  Brigham  and  Women's  Hospital,  Inc.  ("BWH")  in  August  2001.  The  BWH-Purpose
Agreement granted Purpose an exclusive, royalty-bearing, worldwide, sublicensable license, under its rights in licensed patents and patent applications co-
owned by BWH and Purpose to make, use, and sell (1) an apparatus for cultivating a cell or tissue, (2) cell or tissue products made using such apparatus,
(3)  cell  or  tissue  products  made  using  processes  for  cultivating  a  cell  or  tissue  as  disclosed  in  the  licensed  patents  and  patent  applications,  and  (4)  any
apparatus that cultivates cells or tissues using such processes, in each case, whose manufacture, use, or sale is covered by a valid claim of the licensed
patents and patent applications, only for therapeutic use. Pursuant to the Company's sublicense from Purpose, the Company is obligated to pay minimum
royalties and low single-digit royalties based on the net sales of licensed products, milestone payments, and sublicense payments due on the BWH-Purpose
Agreement. Histogenics paid an aggregate of $1.0 million in minimum royalty and sublicense payments under the terms of the Purpose Agreement prior to
the reverse merger.

The Purpose Agreement was amended and restated in June 2012, pursuant to which Purpose granted Histogenics outside of Japan: (i) exclusive rights to all
of Purpose's technology (owned or licensed) related to the exogenous tissue processors, which is used in the development of NeoCart, (ii) continued supply
of exogenous tissue processors, and (iii) rights to manufacture the exogenous tissue processors at any location the Company chooses. In exchange for such
consideration,  Purpose  was  granted  an  exclusive  license  in  Japan  for  the  use  of  all  of  the  Company's  NeoCart  technology  and  was  reimbursed  for
development costs on a multi-unit exogenous tissue processor. In May 2016, the Purpose Agreement was amended, whereby Histogenics reacquired the
development and commercialization rights to NeoCart in Japan.

The  Purpose  Agreement,  as  amended,  provides  the  Company  with  the  ability,  worldwide,  to  (i)  use,  make,  have  made,  sell,  offer  for  sale,  import  or
otherwise  exploit  products  or  services  covered  by  claims  of  Purpose's  patents  and  (ii)  use,  reproduce,  modify,  create  derivative  works  of  and  otherwise
exploit Purpose's technology for the design, development, manufacture, testing, support, and commercialization of any product or service that incorporates
or builds upon Purpose's technology, in each case, only in connection with articular cartilage, ligaments, tendons, and meniscus. Purpose retains the right to
sell its single unit exogenous tissue processer machines to research institutes for general but noncommercial use anywhere in the world.

Under the Purpose Agreement, the Company is obligated to pay Purpose up to $10.0 million upon the achievement of certain regulatory and commercial
milestones as well as a royalty payment in the low single-digits on the net sales in Japan of NeoCart. Such royalty payment shall be reduced to the extent
NeoCart does not rely on an outstanding Purpose patent.

The BWH-Purpose Agreement remains in effect for the life of the licensed patents. The BWH-Purpose Agreement may be terminated if BWH is provided
written notice at least 60 days in advance. BWH has the right to terminate the agreement if minimum royalty payments or other payments fail to be made or
otherwise the BWH-Purpose Agreement is breached and such breach is not cured within 30 days of BWH providing notice. Upon the termination of the
BWH-Purpose Agreement, the Company's sublicense will convert to a nonexclusive license to only Purpose's interest in the licensed products or processes.
Upon written notice to Purpose of the Company's intent to stop using the technology sublicensed to the Company in the BWH-Purpose license, Purpose
will reassume all responsibility under the BWH-Purpose license or at Purpose's option, allow the license to lapse.

In September 2016, pursuant to the U.S. government's Immigrant Investor Program, commonly known as the EB-5 program, the Company entered into an
arrangement (the "EB-5 Loan Agreement") to borrow up to $10.0 million from EB5 Life Sciences, L.P. ("EB-5 Life Sciences") in $0.5 million increments.
Borrowings may be limited by the amount of funds raised by EB-5 Life Sciences and are subject to certain job creation requirements by the Company.
Borrowings are at a fixed interest rate of 4.0% per annum and are to be utilized in the clinical development, manufacturing, and commercialization of the
Company's product candidates and for the general working capital needs of the Company. Outstanding borrowings pursuant to the EB-5 Loan Agreement,
including accrued interest, become due upon the seventh anniversary of the disbursement, subject to certain extension provisions. Amounts repaid cannot
be re-borrowed. The EB-5 Loan Agreement borrowings are secured by substantially all assets of the Company, except for any patents, patent applications,
pending patents, patent licenses, patent sublicenses, trademarks, and other intellectual property rights. Under the terms and conditions of the EB-5 Loan
Agreement, the Company borrowed $1.0 million during 2016, $0.5 million during 2020, and an additional $0.5 million in September 2022. Issuance costs
were recognized as a reduction to the loan balance and are amortized to interest expense over the term of the loan.

million shares of its common stock at an offering price of $7.65 per share in a registered direct offering (the "February 2021 Registered Direct Offering").
Upon the closing of the February 2021 Registered Direct Offering, the Company received net proceeds of $21.2 million after deducting equity issuance
costs of $1.7 million.

COVAXIN Preferred Stock Purchase Agreement

On March 1, 2021, the Company entered into a preferred stock purchase agreement with Bharat Biotech, pursuant to which the Company agreed to issue
and sell 0.1 million shares of the Company's Series B Convertible Preferred Stock, par value $0.01 per share (the "Series B Convertible Preferred Stock"),
at a price per share equal to $109.60, to Bharat Biotech. On March 18, 2021, the Company issued the Series B Convertible Preferred Stock as an advance
payment of $6.0 million for the supply of COVAXIN to be provided by Bharat Biotech pursuant to the Supply Agreement.

Each share of Series B Convertible Preferred Stock is convertible, at the option of Bharat Biotech, into 10 shares of the Company's common stock (the
"Conversion Ratio") only after (i) the Company received stockholder approval to increase the number of authorized shares of common stock under its Sixth
Amended and Restated Certificate of Incorporation, which the Company received in April 2021, and (ii) the Company's receipt of shipments by Bharat
Biotech  of  the  first  10.0  million  doses  of  COVAXIN  manufactured  by  Bharat  Biotech  pursuant  to  the  Supply  Agreement,  and  further  on  the  terms  and
subject  to  the  conditions  set  forth  in  the  Certificate  of  Designation  of  Preferences,  Rights  and  Limitations  of  Series  B  Convertible  Preferred  Stock  (the
"Certificate of Designation"). As of December 31, 2022, the conversion condition relating to the delivery of the first 10.0 million doses of COVAXIN had
not  been  met.  The  conversion  rate  of  the  Series  B  Convertible  Preferred  Stock  is  subject  to  adjustment  in  the  event  of  a  stock  dividend,  stock  split,
reclassification, or similar event with respect to the Company's common stock. Bharat Biotech is entitled to receive dividends on the Series B Convertible
Preferred Stock equal (on an as-converted to common stock basis) to and in the same form as dividends actually paid on shares of common stock, when and
if such dividends are paid. Except as provided by law and certain protective provisions set forth in the Certificate of Designation, the Series B Convertible
Preferred Stock has no voting rights. Upon a liquidation or dissolution of the Company, holders of

F-23

Table of Contents

Series  B  Convertible  Preferred  Stock  would  be  entitled  to  receive  the  same  amount  that  a  holder  of  common  stock  would  receive  if  the  Series  B
Convertible Preferred Stock were fully converted to common stock.

The Company accounted for the issuance of the Series B Convertible Preferred Stock in accordance with ASC 718 and recorded its grant date fair value of
$5.0 million within stockholders' equity during the year ended December 31, 2021, with a corresponding short-term asset for the advanced payment for the
supply  of  COVAXIN  included  in  prepaid  expenses  and  other  current  assets  in  the  consolidated  balance  sheet  as  of  December  31,  2021.  The  Company
utilized the traded common stock price, adjusted by the Conversion Ratio, to value the Series B Convertible Preferred Stock and the Finnerty model to
estimate a 15% discount rate for the lack of marketability of the instrument. The valuation incorporated Level 3 inputs in the fair value hierarchy, including
the estimated time until the instrument's liquidity and estimated volatility of the Company's common stock as of the grant date.

As of December 31, 2022 and 2021, the remaining balance of the short-term asset for the advanced payment for the supply of COVAXIN was $4.1 million
and $5.0 million, respectively. The reduction in the advanced payment resulted from the Company's receipt of COVAXIN drug product components from
Bharat Biotech, which the Company utilized to produce the demonstration batch at Jubilant HollisterStier during the year ended December 31, 2022.

11.    Warrants

Canada Warrants

In July 2021, the Company entered into a consulting agreement with regard to the Company's Canadian operations (the "Canada Consulting Agreement").
Compensation under the Canada Consulting Agreement included the issuance of warrants to purchase up to 0.2 million shares of the Company's common
stock (the "Canada Warrants") and cash payments of up to $3.0 million, both dependent upon the achievement of certain milestones related to COVAXIN.
The Canada Warrants were issued on July 15, 2021, have an exercise price of $6.36 per share, and were accounted for in accordance with ASC 718. The
Canada Consulting Agreement terminates on July 15, 2023 and the Canada Warrants terminate on July 15, 2031, unless earlier terminated in accordance
with their terms. As of December 31, 2022 and 2021, all of the Canada Warrants were outstanding and unvested.

OpCo Warrants

Beginning  in  2016,  OpCo  issued  warrants  to  purchase  the  Company's  common  stock  (the  "OpCo  Warrants").  As  of  December  31,  2022  and  2021,  0.6
million OpCo Warrants were outstanding. As of December 31, 2022, the outstanding OpCo Warrants had a weighted-average exercise price of $6.23 per
share and expire between 2026 and 2027.

outstanding, which is expected to be recognized over a weighted average period of 1.8 years as of December 31, 2022.

Equity Plans

The  Company  maintains  two  equity  compensation  plans,  the  2014  Ocugen  OpCo,  Inc.  Stock  Option  Plan  (the  "2014  Plan")  and  the  Ocugen,  Inc.  2019
Equity  Incentive  Plan  (the  "2019  Plan",  collectively  with  the  2014  Plan,  the  "Plans").  On  the  first  business  day  of  each  fiscal  year,  pursuant  to  the
"Evergreen" provision of the 2019 Plan, the aggregate number of shares that may be issued under the 2019 Plan will automatically increase by a number
equal to the lesser of 4% of the total number of

shares of the Company's common stock outstanding on December 31st of the prior year, or a number of shares determined by the Board of Directors. As of
December  31,  2022,  the  2014  Plan  and  the  2019  Plan  authorize  for  the  granting  of  up  to  0.8  million  and  19.5  million  equity  awards  in  respect  to  the
Company's common stock, respectively. In addition to stock options and RSUs granted under the Plans, the Company has granted certain stock options and
RSUs as material inducements to employment in accordance with Nasdaq Listing Rule 5635 (c)(4), which were granted outside of the Plans.

The Company's valuation allowance increased during 2022 by approximately $15.0 million primarily due to Section 174 expenditure capitalization. The
Company  has  evaluated  both  positive  and  negative  evidence  when  assessing  the  realizability  of  its  deferred  tax  assets.  Management  has  considered  the
Company's history of cumulative net losses, estimated future taxable income as well as tax planning strategies and has concluded that it is more likely than
not that the Company will not realize the benefits of its deferred tax assets. Accordingly, a full valuation allowance has been established against these net
deferred tax assets as of December 31, 2022 and 2021, respectively.

F-26

Table of Contents

As  of  December  31,  2022  and  2021,  the  Company  had  U.S.  federal  net  operating  loss  ("NOL")  carryforwards  of  $200.5  million  and  $184.4  million,
respectively, which may be available to offset future income tax liabilities. The 2017 Tax Cut and Jobs Act generally allows federal losses generated after
2017 to be carried over indefinitely, but also limits the NOL deduction to the lesser of the NOL carryover or 80% of a corporation's taxable income (subject
to Section 382 of the Internal Revenue Code of 1986, as amended ("IRC")). Additionally, there is no carryback for losses generated after 2017. Losses
generated prior to 2018 are deductible using the lesser of a corporation's NOL carryover or 100% of a corporation's taxable income and have a 20 year
carryforward period. The Company has federal NOLs generated after 2017 of $147.9 million, which do not expire. The federal NOLs generated prior to
2018 of $52.6 million will expire at various dates through 2037. In addition, the Company has a capital loss carryforward of $26.7 million, which may be
available to offset future capital gains and expires in 2024.

As of December 31, 2022 and 2021, the Company had U.S. state NOL carryforwards of $198.9 million and $183.1 million, respectively, which may be
available to offset future income tax liabilities and expire at various dates through 2042. As of December 31, 2022 and 2021, the Company had federal tax
credit carryforwards of approximately $6.5 million and $3.8 million, respectively, which are available to offset future federal tax liabilities which expire at
various  dates  through  2042.  As  of  December  31,  2022  and  2021,  the  Company  had  state  tax  credit  carryforwards  of  approximately  $0.2  million  and
$0.7 million, respectively, which are available to reduce future tax liabilities and expire at various dates through 2034.

NOL  and  tax  credit  carryforwards  are  subject  to  review  and  possible  adjustment  by  the  Internal  Revenue  Service  and  relevant  state  tax  authorities.
Utilization  of  NOL  and  tax  credit  carryforwards  may  be  subject  to  a  substantial  annual  limitation  under  Section  382  and  Section  383  of  the  IRC  and
corresponding provisions of state law, due to ownership changes that have occurred previously or that could occur in the future. These ownership changes
may limit the amount of NOL and tax credit carryforwards that can be utilized annually to offset future federal and state tax liabilities.

The Company has not yet conducted a comprehensive study to assess whether any ownership change has occurred since its inception. A limitation may
result  in  the  expiration  of  a  portion  of  the  NOL  or  tax  credit  carryforwards  before  utilization,  which  would  be  offset  by  a  change  in  the  Company's
valuation allowance. Until a study is completed by the Company, no NOL carryforward amounts will be offset by an unrecognized tax benefit related to
Section 382.

A full valuation allowance has also been recorded against the Company's tax credits. If an adjustment is required, it would be offset by a corresponding
change in the valuation allowance.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

Gross unrecognized tax benefits at beginning of year
Additions for tax positions taken in a prior year
Additions for tax positions taken in the current year
Reductions for tax positions taken in the prior year due to settlement
Reductions for tax positions taken in the prior year due to statutes lapsing

The  uncertain  tax  positions  giving  rise  to  the  unrecognized  tax  benefits  of  $0.3  million  at  December  31,  2022  and  2021  relate  to  the  timing  of  certain
income  and  deductions  for  federal  income  tax  purposes  taken  by  Histogenics  prior  to  the  Company's  reverse  merger  with  Histogenics.  The  reversal  of
unrecognized tax benefits would not have any impact on the effective tax rate in the future and is not expected to create cash liability.

The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In a normal course of business, the Company is subject
to examination by federal and state jurisdictions, where applicable. The Company's tax years are still open from 2019 to present.

The  Company  has  commitments  under  certain  license  and  development  agreements,  lease  agreements,  debt  agreements,  and  consulting  agreements.
Commitments  under  certain  license  and  development  agreements  include  annual  payments,  payments  upon  the  achievement  of  certain  milestones,  and
royalty payments based on net sales of licensed products (see Note 3). Commitments under lease agreements are future minimum lease payments (see Note
7).  Commitments  under  debt  agreements  are  the  future  payment  of  principal  and  accrued  interest  under  the  EB-5  Loan  Agreement  (see  Note  9).
Commitments under consulting agreements include payments upon the achievement of certain milestones related to COVAXIN (see Note 11).

Contingencies

In June 2021, a securities class action lawsuit was filed against the Company and certain of its agents in the U.S. District Court for the Eastern District of
Pennsylvania  ("Court")  (Case  No.  2:21-cv-02725)  that  purported  to  state  a  claim  for  alleged  violations  of  Sections  10(b)  and  20(a)  of  the  Securities
Exchange  Act  of  1934  (the  "Exchange  Act")  and  Rule  10b-5  promulgated  thereunder,  based  on  statements  made  by  the  Company  concerning  the
announcement of the Company's decision to pursue the submission of a BLA for COVAXIN for adults ages 18 years and older rather than pursuing an
EUA for the vaccine candidate. In July 2021, a second securities class action lawsuit was filed against the Company and certain of its agents in the Court
(Case  No.  2:21-cv-03182)  that  also  purported  to  state  a  claim  for  alleged  violations  of  Sections  10(b)  and  20(a)  of  the  Exchange  Act  and  Rule  10b-5
promulgated thereunder, based on the same statements as the first complaint. The complaints seek unspecified damages, interest, attorneys' fees, and other
costs. In March 2022, the Court consolidated these two related securities class action lawsuits and appointed Andre Galan Bernd Benayon to serve as lead
plaintiff. The lead plaintiff's amended complaint was filed in June 2022. The Company filed a motion to dismiss the amended complaint in August 2022.
The  lead  plaintiff's  opposition  to  the  motion  to  dismiss  was  filed  in  October  2022.  The  Company  filed  its  reply  in  support  of  the  motion  to  dismiss  in
November 2022. Oral argument on the motion to dismiss took place in January 2023 and no decision has been made to date by the Court. As with any
litigation,  the  Company  cannot  predict  the  outcome  with  certainty,  but  the  Company  expects  to  provide  further  updates  on  the  status  of  the  motion  to
dismiss as available.

In August 2021, a stockholder derivative lawsuit was filed derivatively on behalf of the Company against certain of its agents and the nominal defendant
Ocugen in the Court (Case No. 2:21-cv-03876) that purported to state a claim for breach of fiduciary duty and contribution for violations of Sections 10(b)
and 21(d) of the Exchange Act, based on facts and circumstances relating

F-28

Table of Contents

to the securities class action lawsuits and seeking contribution and indemnification in connection with claims asserted in the securities class action lawsuits.
In September 2021, a second stockholder derivative lawsuit was filed derivatively on behalf of the Company against certain of its agents and the nominal
defendant Ocugen in the Court (Case No. 2:21-cv-04169) that purported to state a claim for breach of fiduciary duties, unjust enrichment, abuse of control,
waste  of  corporate  assets,  and  contribution  for  violations  of  Sections  10(b)  and  21(d)  of  the  Exchange  Act,  based  on  the  same  allegations  as  the  first
complaint. The parties to both stockholder derivative lawsuits have stipulated to the consolidation of the two stockholder derivative lawsuits and also have
submitted to the Court in each action a proposed order requesting a stay of the litigation pending a decision on any motion to dismiss filed in the securities
class action lawsuits, which the Court entered in April 2022.

The Company believes that the lawsuits are without merit and intends to vigorously defend against them. At this time, no assessment can be made as to
their likely outcome or whether the outcome will be material to the Company. No information is available to indicate that it is probable that a loss has been
incurred and can be reasonably estimated as of the date of the consolidated financial statements and, as such, no accrual for the loss has been recorded
within the consolidated financial statements.

16.    Subsequent Events

Subsequent  to  December  31,  2022,  the  Company  sold  4.5  million  shares  of  its  common  stock  under  the  Sales  Agreement.  The  Company  received  net
proceeds of $5.6 million after deducting equity issuance costs of $0.2 million. See Note 10 for additional information regarding the Sales Agreement.

OCUGEN, INC.
INCENTIVE STOCK OPTION AGREEMENT

Exhibit 10.5

THIS INCENTIVE STOCK OPTION AGREEMENT (“Agreement”) is made and entered into as of the ___ day of ____________, 20___ (the

“Grant Date”), by and between Ocugen, Inc., a Delaware corporation (the “Company”), and ________________, an individual (the “Optionee”).

W I T N E S S E T H:

WHEREAS,  pursuant  to  the  Ocugen,  Inc.  2019  Equity  Incentive  Plan  (the  “Plan”),  the  Company  desires  to  grant  to  Optionee,  and  Optionee
desires to accept, an option to purchase shares of the common stock of the Company, par value $.01 per share (the “Common Stock”), upon the terms and
conditions set forth in this Agreement and the Plan.

NOW, THEREFORE, the parties hereto agree as follows:

1.

Definitions. All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Plan.

2.

Grant. Subject  to  the  terms  hereof,  Optionee  is  hereby  awarded  an  option  (the  “Option”)  to  purchase  ________________  shares  of
Common Stock (the “Option Shares”) at a price of _____ per share (the “Option Price”), which price has been determined by the Committee to be at least
the Fair Market Value per Share on the Grant Date; provided, however, that if the Optionee then owns, directly or by attribution under Section 424(b) of the
Code, shares possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any parent or subsidiary
of the Company, then the Option Price shall be at least one hundred ten percent (110%) of the Fair Market Value per share on the Grant Date. Subject to the
limitations of Section 422(d) of the Code, the Option is intended to qualify as an incentive stock option (“ISO”) within the meaning of Section 422 of the
Code. To  the  extent  that  the  Option  does  not  qualify  as  an  ISO,  it  will  be  treated  as  a  non-qualified  stock  option.  In  any  case,  the  Company  does  not
guaranty the tax treatment of the Option. The Option Price of the Option Shares shall be paid at the time of exercise, as provided in Section 3 hereof.

3.

Exercise.

a.

Except  as  specifically  provided  otherwise  herein  or  in  the  Plan,  the  Option  will  become  exercisable  in  accordance  with  the

following schedule, provided Optionee remains in continuous service with the Company through the applicable vesting date:

[insert vesting schedule]

For purposes of this Agreement, service with the Company will be deemed to include service with an Affiliate (for only so long as such entity remains an
Affiliate).

b.

The  Option  may  be  exercised  in  whole  or  in  part  in  accordance  with  this  Section  3  by  delivering  to  the  Secretary  of  the
Company (1) a written notice specifying the number of Shares to be purchased, and (2) payment in full of the Option Price with respect to the Shares to be
purchased, together with the amount, if any, deemed necessary by the Company to enable it to satisfy any income tax withholding obligations with respect
to the exercise (unless other arrangements, acceptable to the Company, are made for the satisfaction of such withholding obligations). The Option Price
may be paid by check, electronic funds transfer, or if permitted by the Committee, in the form of previously acquired Shares based on the Fair Market
Value of those Shares on the date the Option is exercised or by means of a net cashless exercise.

c.

Unless sooner terminated, to the extent not sooner exercised, the Option will terminate ten (10) years from the Grant Date (or
five (5) years from the Grant Date, if on the Grant Date the Optionee owns, directly or by attribution under Section 424(b) of the Code, shares possessing
more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any parent or subsidiary of the Company).

4.

Termination.

a.

If  Optionee  ceases  to  perform  services  for  the  Company  for  any  reason,  any  portion  of  the  Option  that  then  remains
unexercisable (taking into account any accelerated vesting occurring upon such cessation of service) will expire immediately upon the effective date of
Optionee’s cessation of service. If such cessation occurs other than by reason of Optionee’s death or total disability (within the meaning of the Plan), then,
unless sooner terminated or exercised under the terms hereof, the exercisable portion of the Option will terminate three (3) months after the effective date
of  Optionee’s  cessation  of  service;  provided, however,  that  if  the  Company  terminates  the  Optionee’s  service  for  Cause  (as  defined  below),  the  entire
Option will terminate immediately upon the effective date of Optionee’s cessation of service. If Optionee’s service ceases by reason of Optionee’s death or
total disability, then, unless sooner terminated or exercised under the terms hereof, the exercisable portion of the Option will terminate on the date one (1)
year after the date of such cessation of service.

b.

For  purposes  of  this  Agreement,  “Cause”  will  have  the  meaning  defined  in  any  employment  or  similar  service  agreement
between  the  Company  and  Optionee;  provided  that  if  no  such  agreement  exists,  “Cause”  will  mean  (i)  failure  or  refusal  by  Optionee  to  substantially
perform his or her duties, or breach by Optionee of the written rules or policies of the Company, which failure, refusal or breach continues for fifteen (15)
days after written notice thereof is provided to Optionee; (ii) Optionee’s gross negligence or willful misconduct in the course of his or her service; (iii)
Optionee’s  commission  of  fraud  or  theft;  (iv)  Optionee’s  conviction  of,  or  plea  of  no  contest  to,  a  felony;  or  (v)  material  breach  by  Optionee  of  any
agreement with, or duty owed to, the Company or any Affiliate.

5.

Change in Control. In the event of a Change in Control, the Option shall become immediately vested and exercisable with respect to
100% of Option Shares. For avoidance of doubt, the immediately preceding “single trigger” vesting acceleration applies to this Award, even if the Optionee
also has an employment agreement with the Company that provides for “double trigger” vesting acceleration (i.e., acceleration of equity vesting upon a
severance  event  proximate  to  a  Change  in  Control),  and  this  Agreement  will  control  treatment  of  vesting  acceleration  of  this  Award  upon  a  Change  in
Control in the event of any conflict with the terms of such employment agreement.

6.

Rights as Stockholder. No shares of Common Stock shall be sold or delivered hereunder until full payment for such shares has been
made. Optionee shall have no rights as a stockholder with respect to any Option Shares until such shares are issued to him or her (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer agent).

7.

Nontransferability.  The  Option  is  not  assignable  or  transferable  except  by  will  or  the  laws  of  descent  and  distribution.  During

Optionee’s lifetime, the option may be exercised only by Optionee or, in the event of Optionee’s total disability, Optionee’s legal representative.

8.

Securities Restrictions. If a registration statement is not in effect under the Securities Act of 1933 or any applicable state securities laws
with respect to the Option Shares, the Board may require, as a condition of exercise of the Option that the Optionee represent, in writing, that (a) such
Option Shares are being purchased for investment and not for distribution or resale, (b) the Optionee has been advised and understands that (i) the Option
Shares have not been registered under the Act and are “restricted securities” within the meaning of Rule 144 under the Act and are subject to restrictions on
transfer and (ii) the Company is under no obligation to register the Option Shares under the Act or to take any action which would make available to the
Optionee any exemption from such registration, (c) such Option Shares may not be transferred without compliance with all applicable federal and state
securities laws, and (d) an appropriate legend referring to the foregoing restrictions may be endorsed on the certificates.

9.

No Right to Continued Service. Nothing in this Agreement shall give Optionee any right to continued employment or service with the

Company or interfere in any way with the right of the Company to terminate the employment or service of Optionee at any time, with or without cause.

10.

Provisions of Plan. The provisions of the Plan shall govern if and to the extent that there are inconsistencies between those provisions

and the provisions hereof. Optionee acknowledges receipt of a copy of the Plan prior to the execution of this Agreement.

11.

Administration. The Board or the committee appointed by the Board to administer the Plan, if any, will have full power and authority to
interpret and apply the provisions of this Agreement and act on behalf of the Company in connection with this Agreement, and the decision of said Board

12.

Company Policies. Optionee agrees, in consideration for the grant of the Option, to be subject to any policies of the Company regarding
clawbacks, securities trading and hedging or pledging of securities that may be in effect from time to time, or as may otherwise be required by applicable
law, regulation or exchange listing standard.

13.

Certain Dispositions of Option Shares. Optionee acknowledges that the tax rules described in Section 421(a) of the Code will not apply
to any Option Shares issued to the Optionee pursuant to the exercise of this Option if such Option Shares are disposed of either (a) within two (2) years of
the Grant Date, or (b) within one (1) year of the issuance of such Option Shares to the Optionee upon exercise (a “Disqualifying Disposition”). Optionee
shall give prompt, written notice to the Company of any Disqualifying Disposition.

NON-QUALIFIED STOCK OPTION AGREEMENT

Exhibit 10.6

THIS NON-QUALIFIED STOCK OPTION AGREEMENT (“Agreement”) is made and entered into as of _____________ (the “Grant Date”), by

and between Ocugen, Inc., a Delaware corporation (the “Company”), and ________________, an individual (the “Optionee”).

W I T N E S S E T H:

WHEREAS,  pursuant  to  the  Ocugen,  Inc.  2019  Equity  Incentive  Plan  (the  “Plan”),  the  Company  desires  to  grant  to  Optionee,  and  Optionee
desires to accept, an option to purchase shares of the common stock of the Company, par value $.01 per share (the “Common Stock”), upon the terms and
conditions set forth in this Agreement and the Plan.

NOW, THEREFORE, the parties hereto agree as follows:

1.

Definitions. All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Plan.

2.

Grant. Subject  to  the  terms  hereof,  Optionee  is  hereby  awarded  an  option  (the  “Option”)  to  purchase  ________________  shares  of
Common Stock (the “Option Shares”) at a price of _____ per share (the “Option Price”), which price has been determined by the Committee to be at least
the Fair Market Value per Share on the Grant Date. The Option is not intended to qualify as an incentive stock option within the meaning of Section 422 of
the Code. The Option Price of the Option Shares shall be paid at the time of exercise, as provided in Section 3 hereof.

3.

Exercise.

a.

Except  as  specifically  provided  otherwise  herein  or  in  the  Plan,  the  Option  will  become  exercisable  in  accordance  with  the

following schedule, provided Optionee remains in continuous service with the Company through the applicable vesting date:

[insert vesting schedule]

For purposes of this Agreement, service with the Company will be deemed to include service with an Affiliate (for only so long as such entity remains an
Affiliate).

b.

The  Option  may  be  exercised  in  whole  or  in  part  in  accordance  with  this  Section  3  by  delivering  to  the  Secretary  of  the
Company (1) a written notice specifying the number of Shares to be purchased, and (2) payment in full of the Option Price with respect to the Shares to be
purchased, together with the amount, if any, deemed necessary by the Company to enable it to satisfy any income tax withholding obligations with respect
to the exercise (unless other arrangements, acceptable to the Company, are made for the satisfaction of such withholding obligations). The Option Price
may be paid by check, electronic funds transfer or as otherwise provided in the Plan.

c.

Unless sooner terminated, to the extent not sooner exercised, the Option will terminate ten (10) years from the Grant Date.

4.

Termination.

a.

If  Optionee  ceases  to  perform  services  for  the  Company  for  any  reason,  any  portion  of  the  Option  that  then  remains
unexercisable (taking into account any accelerated vesting occurring upon such cessation of service) will expire immediately upon the effective date of
Optionee’s cessation of service. If such cessation

    1    

occurs other than by reason of Optionee’s death or total disability (within the meaning of the Plan), then, unless sooner terminated or exercised under the
terms hereof, the exercisable portion of the Option will terminate three (3) months after the effective date of Optionee’s cessation of service; provided,
however,  that  if  the  Company  terminates  the  Optionee’s  service  for  Cause  (as  defined  below),  the  entire  Option  will  terminate  immediately  upon  the
effective  date  of  Optionee’s  cessation  of  service.  If  Optionee’s  service  ceases  by  reason  of  Optionee’s  death  or  total  disability,  then,  unless  sooner
terminated or exercised under the terms hereof, the exercisable portion of the Option will terminate on the date one (1) year after the date of such cessation
of service.

b.

For  purposes  of  this  Agreement,  “Cause”  will  have  the  meaning  defined  in  any  employment  or  similar  service  agreement
between  the  Company  and  Optionee;  provided  that  if  no  such  agreement  exists,  “Cause”  will  mean  (i)  failure  or  refusal  by  Optionee  to  substantially
perform his or her duties, or breach by Optionee of the written rules or policies of the Company, which failure, refusal or breach continues for fifteen (15)
days after written notice thereof is provided to Optionee; (ii) Optionee’s gross negligence or willful misconduct in the course of his or her service; (iii)
Optionee’s  commission  of  fraud  or  theft;  (iv)  Optionee’s  conviction  of,  or  plea  of  no  contest  to,  a  felony;  or  (v)  material  breach  by  Optionee  of  any
agreement with, or duty owed to, the Company or any Affiliate.

5.

Change in Control. In the event of a Change in Control, the Option shall become immediately vested and exercisable with respect to
100% of Option Shares. For avoidance of doubt, the immediately preceding “single trigger” vesting acceleration applies to this Award, even if the Optionee
also has an employment agreement with the Company that provides for “double trigger” vesting acceleration (i.e., acceleration of equity vesting upon a
severance  event  proximate  to  a  Change  in  Control),  and  this  Agreement  will  control  treatment  of  vesting  acceleration  of  this  Award  upon  a  Change  in
Control in the event of any conflict with the terms of such employment agreement.

6.

Rights as Stockholder. No shares of Common Stock shall be sold or delivered hereunder until full payment for such shares has been
made. Optionee shall have no rights as a stockholder with respect to any Option Shares until such shares are issued to him or her (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer agent).

7.

Nontransferability.  The  Option  is  not  assignable  or  transferable  except  by  will  or  the  laws  of  descent  and  distribution.  During

Optionee’s lifetime, the option may be exercised only by Optionee or, in the event of Optionee’s total disability, Optionee’s legal representative.

8.

Securities Restrictions. If a registration statement is not in effect under the Securities Act of 1933 or any applicable state securities laws
with respect to the Option Shares, the Board may require, as a condition of exercise of the Option that the Optionee represent, in writing, that (a) such
Option Shares are being purchased for investment and not for distribution or resale, (b) the Optionee has been advised and understands that (i) the Option
Shares have not been registered under the Act and are “restricted securities” within the meaning of Rule 144 under the Act and are subject to restrictions on

3.

Date of Grant. The Restricted Stock Units were granted on the Grant Date set forth in the Grant Notice.

(c)

Notwithstanding the foregoing, to the extent provided in Prop. Treas. Reg. § 1.409A-1(b)(4)(ii) or any successor provision, the
Company may delay settlement of Restricted Stock Units if it reasonably determines that such settlement would violate federal securities laws or any other
applicable law.

6.

Non-Transferability  of  Restricted  Stock  Units.  The  Restricted  Stock  Units  may  not  be  sold,  pledged,  assigned,  hypothecated,  gifted,
transferred or disposed of in any manner, either voluntarily or involuntarily, by operation of law or otherwise, other than by will or by the laws of descent
and distribution.

applicable laws or regulations.

Tax Consequences. The Participant acknowledges that the Company has not advised the Participant regarding the Participant’s income
tax  liability  in  connection  with  the  grant  of  the  Restricted  Stock  Units  and  that  the  Company  does  not  guarantee  any  particular  tax  treatment.  The
Participant acknowledges that the Participant has reviewed with the Participant’s own tax advisors the tax treatment of the Restricted Stock Units and is
relying  solely  on  those  advisors  in  that  regard.  The  Participant  understands  that  the  Participant  (and  not  the  Company)  will  be  responsible  for  the
Participant’s own tax liabilities arising in connection with the Restricted Stock Units.

9.

No Continuation of Service. Neither the Plan nor this Agreement will confer upon the Participant any right to continue in the employment
or service of the Company or any of its Affiliates, or limit in any respect the right of the Company or its Affiliates to discharge the Participant at any time,
with or without cause and with or without notice.

10.

Withholding. The Company is hereby authorized to withhold from any consideration payable or property transferable to the Participant

any taxes required to be withheld in connection with the Restricted Stock Units.

11.

Company Policies. In consideration for the grant of the Restricted Stock Units, the Participant agrees to be subject to the policies of the

Company regarding clawback, securities trading and hedging or pledging of securities, as in effect from time to time.

Restricted Stock Units subject to the terms and provisions of the Plan. Pursuant to the Plan, the Committee is authorized to interpret the Plan and to adopt
rules and regulations not inconsistent with the Plan as it deems appropriate. The Participant hereby agrees to accept as binding, conclusive and final all
decisions or interpretations of the Committee with respect to questions arising under the Plan, the Grant Notice or this Agreement.

13.

Entire Agreement. The Grant Notice and this Agreement, together with the Plan, represents the entire agreement between the parties with

respect to the subject matter hereof and supersedes any prior agreement, written or otherwise, relating to the subject matter hereof.

14.

Amendment. Except as otherwise provided herein, in the Grant Notice or in the Plan, or as would otherwise not have a material adverse

effect on the Participant, this Agreement may only be amended by a writing signed by each of the parties hereto.

15.

Governing  Law.  This  Agreement  will  be  construed  in  accordance  with  the  laws  of  the  State  of  Delaware,  without  regard  to  the

application of the principles of conflicts of laws.

Exhibit 10.9

THIS  NON-QUALIFIED  STOCK  OPTION  INDUCEMENT  AWARD  AGREEMENT  (“Agreement”)  is  made  and  entered  into  as  of
_____________ (the “Grant Date”), by and between Ocugen, Inc., a Delaware corporation (the “Company”), and ________________, an individual (the
“Optionee”).

W I T N E S S E T H:

WHEREAS, to induce Optionee to commence employment with the Company, the Company desires to grant to Optionee an option to purchase

shares of the common stock of the Company, par value $.01 per share (the “Common Stock”), on the terms and conditions set forth in this Agreement.

NOW, THEREFORE, the parties hereto agree as follows:

1.

Inducement Award.  This  stock  option  is  an  inducement  grant,  as  described  in  NASDAQ  Listing  Rule  5635(c)(4).  Accordingly,  this
stock  option  has  been  granted  outside  of  the  Company’s  2019  Equity  Incentive  Plan  (the  “Plan”).  However,  the  terms  of  the  Plan  applicable  to  non-
qualified stock options are incorporated herein, as if this stock option had been issued under the Plan. All capitalized terms not otherwise defined herein
shall have the meanings ascribed to them in the Plan.

2.

Grant. Subject  to  the  terms  hereof,  Optionee  is  hereby  awarded  an  option  (the  “Option”)  to  purchase  ________________  shares  of
Common Stock (the “Option Shares”) at a price of _____ per share (the “Option Price”), which price has been determined by the Committee to be at least
the Fair Market Value per Share on the Grant Date. The Option is not intended to qualify as an incentive stock option within the meaning of Section 422 of
the Code. The Option Price of the Option Shares shall be paid at the time of exercise, as provided in Section 3 hereof.

3.

Exercise.

a.

Except  as  specifically  provided  otherwise  herein  or  in  the  Plan,  the  Option  will  become  exercisable  in  accordance  with  the

following schedule, provided Optionee remains in continuous service with the Company through the applicable vesting date:

[insert vesting schedule]

For purposes of this Agreement, service with the Company will be deemed to include service with an Affiliate (for only so long as such entity remains an
Affiliate).

b.

The  Option  may  be  exercised  in  whole  or  in  part  in  accordance  with  this  Section  3  by  delivering  to  the  Secretary  of  the
Company (1) a written notice specifying the number of Shares to be purchased, and (2) payment in full of the Option Price with respect to the Shares to be
purchased, together with the amount, if any, deemed necessary by the Company to enable it to satisfy any income tax withholding obligations with respect
to the exercise (unless other arrangements, acceptable to the Company, are made for the satisfaction of such withholding obligations). The Option Price
may be paid by check, electronic funds transfer or as otherwise provided in the Plan.

c.

Unless sooner terminated, to the extent not sooner exercised, the Option will terminate ten (10) years from the Grant Date.

4.

Termination.

a.

If  Optionee  ceases  to  perform  services  for  the  Company  for  any  reason,  any  portion  of  the  Option  that  then  remains
unexercisable (taking into account any accelerated vesting occurring upon such cessation of service) will expire immediately upon the effective date of
Optionee’s cessation of service. If such cessation occurs other than by reason of Optionee’s death or total disability (as that term is used within the Plan),
then, unless sooner terminated or exercised under the terms hereof, the exercisable portion of the Option will terminate three (3) months after the effective
date of Optionee’s cessation of service; provided, however, that if the Company terminates the Optionee’s service for Cause (as defined below), the entire
Option will terminate immediately upon the effective date of Optionee’s cessation of service. If Optionee’s service ceases by reason of Optionee’s death or
total disability, then, unless sooner terminated or exercised under the terms hereof, the exercisable portion of the Option will terminate on the date one (1)
year after the date of such cessation of service.

b.

For  purposes  of  this  Agreement,  “Cause”  will  have  the  meaning  defined  in  any  employment  or  similar  service  agreement
between  the  Company  and  Optionee;  provided  that  if  no  such  agreement  exists,  “Cause”  will  mean  (i)  failure  or  refusal  by  Optionee  to  substantially
perform his or her duties, or breach by Optionee of the written rules or policies of the Company, which failure, refusal or breach continues for fifteen (15)
days after written notice thereof is provided to Optionee; (ii) Optionee’s gross negligence or willful misconduct in the course of his or her service; (iii)
Optionee’s  commission  of  fraud  or  theft;  (iv)  Optionee’s  conviction  of,  or  plea  of  no  contest  to,  a  felony;  or  (v)  material  breach  by  Optionee  of  any
agreement with, or duty owed to, the Company or any Affiliate.

5.

Change in Control. In the event of a Change in Control, the Option shall become immediately vested and exercisable with respect to
100% of Option Shares. For avoidance of doubt, the immediately preceding “single trigger” vesting acceleration applies to this Award, even if the Optionee
also has an employment agreement with the Company that provides for “double trigger” vesting acceleration (i.e., acceleration of equity vesting upon a
severance  event  proximate  to  a  Change  in  Control),  and  this  Agreement  will  control  treatment  of  vesting  acceleration  of  this  Award  upon  a  Change  in
Control in the event of any conflict with the terms of such employment agreement.

6.

Rights as Stockholder. No shares of Common Stock shall be sold or delivered hereunder until full payment for such shares has been
made. Optionee shall have no rights as a stockholder with respect to any Option Shares until such shares are issued to him or her (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer agent).

7.

Nontransferability.  The  Option  is  not  assignable  or  transferable  except  by  will  or  the  laws  of  descent  and  distribution.  During

Optionee’s lifetime, the option may be exercised only by Optionee or, in the event of Optionee’s total disability, Optionee’s legal representative.

8.

Securities Restrictions. If a registration statement is not in effect under the Securities Act of 1933 or any applicable state securities laws
with respect to the Option Shares, the Board may require, as a condition of exercise of the Option that the Optionee represent, in writing, that (a) such
Option Shares are being purchased for investment and not for distribution or resale, (b) the Optionee has been advised and understands that (i) the Option
Shares have not been registered under the Act and are “restricted securities” within the meaning of Rule 144 under the Act and are subject to restrictions on
transfer and (ii) the Company is under no obligation to register the Option Shares under the Act or to take any action which would make available to the
Optionee any exemption from such registration, (c) such Option Shares may not be transferred without compliance with all applicable federal and state
securities laws, and (d) an appropriate legend referring to the foregoing restrictions may be endorsed on the certificates.

9.

No Right to Continued Service. Nothing in this Agreement shall give Optionee any right to continued employment or service with the

Company or interfere in any way with the right of the Company to terminate the employment or service of Optionee at any time, with or without cause.

-2-

10.

Receipt of Plan. Optionee acknowledges receipt of a copy of the Plan prior to the execution of this Agreement.

11.

Administration. The Board or the committee appointed by the Board to administer the Plan, if any, will have full power and authority to
interpret and apply the provisions of this Agreement and act on behalf of the Company in connection with this Agreement, and the decision of said Board

EXHIBIT A

RESTRICTED STOCK UNIT INDUCEMENT AWARD AGREEMENT

1.

Award of Restricted Stock Units. The Company has granted to the Participant the number of Restricted Stock Units set forth in the Grant
Notice, upon the terms and conditions set forth in the Grant Notice and this Agreement. This is an “inducement grant,” as described in NASDAQ Listing
Rule 5635(c)(4). Accordingly, the Restricted Stock Units have been granted outside of the Company’s 2019 Equity Incentive Plan (the “Plan”). However,
the  terms  of  the  Plan  applicable  to  restricted  stock  units  are  incorporated  herein,  as  if  the  Restricted  Stock  Units  had  been  issued  under  the  Plan.  Each
Restricted Stock Unit represents the right to receive one Share at the times and subject to the conditions set forth herein.

2.

3.

Date of Grant. The Restricted Stock Units were granted on the Grant Date set forth in the Grant Notice.

Vesting of Restricted Stock Units.

Stock Units shall become vested in such amounts and at such times as are set forth in the Grant Notice.

(a)

Vesting. Subject to the continued service of the Participant with the Company through the relevant vesting dates, the Restricted

(b)

Service with Affiliates. Solely for purposes of this Agreement, service with the Company will be deemed to include service with

any Affiliate of the Company (for only so long as such entity remains an Affiliate of the Company).

Restricted Stock Units (taking into account any accelerated vesting occurring upon such cessation of service) shall be forfeited immediately.

(c)

Effect of Termination of Service. If the Participant’s service with the Company ceases for any reason, the unvested portion of the

4.

Change in Control. In the event of a Change in Control, any unvested portion of the Restricted Stock Units shall immediately become
100% vested. For avoidance of doubt, the immediately preceding “single trigger” vesting acceleration applies to this Award, even if the Participant also has
an employment agreement with the Company that provides for “double trigger” vesting acceleration (i.e., acceleration of equity vesting upon a severance
event proximate to a Change in Control), and this Agreement will control treatment of vesting acceleration of this Award upon a Change in Control in the
event of any conflict with the terms of such employment agreement.

5.

Settlement of Restricted Stock Units.

(a)

Shares will be issued in respect of vested Restricted Stock Units within sixty (60) days following the applicable vesting date. For

avoidance of doubt, this deadline is intended to comply with the “short-term deferral” exemption from Section 409A of the Code.

(b)

The  Restricted  Stock  Units  will  not  confer  on  the  Participant  any  rights  as  a  stockholder  of  the  Company  until  Shares  are

actually issued in settlement of such Restricted Stock Units.

(c)

Notwithstanding the foregoing, to the extent provided in Prop. Treas. Reg. § 1.409A-1(b)(4)(ii) or any successor provision, the
Company may delay settlement of Restricted Stock Units if it reasonably determines that such settlement would violate federal securities laws or any other
applicable law.

6.

Non-Transferability  of  Restricted  Stock  Units.  The  Restricted  Stock  Units  may  not  be  sold,  pledged,  assigned,  hypothecated,  gifted,
transferred or disposed of in any manner, either voluntarily or involuntarily, by operation of law or otherwise, other than by will or by the laws of descent
and distribution.

A-1

7.

Investment Representations. The Participant represents and warrants to the Company that the Participant is acquiring the Restricted Stock
Units (and upon settlement of the Restricted Stock Units, may be acquiring Shares) for investment for the Participant’s own account, not as a nominee or
agent, and not with a view to, or for resale in connection with, any distribution thereof. As a further condition to the settlement of the Restricted Stock
Units, the Board may require that certain agreements, undertakings, representations, certificates, legends and/or information or other matters, as the Board
may  deem  necessary  or  advisable,  be  executed,  agreed  to  and/or  provided  to  the  Company  to  assure  compliance  with  all  such  applicable  laws  or
regulations.

8.

Tax Consequences. The Participant acknowledges that the Company has not advised the Participant regarding the Participant’s income
tax  liability  in  connection  with  the  grant  of  the  Restricted  Stock  Units  and  that  the  Company  does  not  guarantee  any  particular  tax  treatment.  The
Participant acknowledges that the Participant has reviewed with the Participant’s own tax advisors the tax treatment of the Restricted Stock Units and is
relying  solely  on  those  advisors  in  that  regard.  The  Participant  understands  that  the  Participant  (and  not  the  Company)  will  be  responsible  for  the
Participant’s own tax liabilities arising in connection with the Restricted Stock Units.

9.

No Continuation of Service. Neither the Plan nor this Agreement will confer upon the Participant any right to continue in the employment
or service of the Company or any of its Affiliates, or limit in any respect the right of the Company or its Affiliates to discharge the Participant at any time,
with or without cause and with or without notice.

10.

Withholding. The Company is hereby authorized to withhold from any consideration payable or property transferable to the Participant

any taxes required to be withheld in connection with the Restricted Stock Units.

11.

Company Policies. In consideration for the grant of the Restricted Stock Units, the Participant agrees to be subject to the policies of the

Company regarding clawback, securities trading and hedging or pledging of securities, as in effect from time to time.

12.

The  Plan.  The  Participant  has  received  a  copy  of  the  Plan,  has  read  the  Plan  and  is  familiar  with  its  terms,  and  hereby  accepts  the
Restricted Stock Units subject to the terms and provisions of the Plan incorporated herein. Pursuant to the Plan, the Committee is authorized to interpret the
Plan  and  to  adopt  rules  and  regulations  not  inconsistent  with  the  Plan  as  it  deems  appropriate.  The  Participant  hereby  agrees  to  accept  as  binding,
conclusive and final all decisions or interpretations of the Committee with respect to questions arising under the Plan, the Grant Notice or this Agreement.

13.

Entire Agreement. The  Grant  Notice  and  this  Agreement,  together  with  the  Plan  provisions  incorporated  herein,  represents  the  entire
agreement between the parties with respect to the subject matter hereof and supersedes any prior agreement, written or otherwise, relating to the subject
matter hereof.

14.

Amendment. Except as otherwise provided herein, in the Grant Notice or in the Plan, or as would otherwise not have a material adverse

effect on the Participant, this Agreement may only be amended by a writing signed by each of the parties hereto.

15.

Governing  Law.  This  Agreement  will  be  construed  in  accordance  with  the  laws  of  the  State  of  Delaware,  without  regard  to  the

application of the principles of conflicts of laws.

16.

Execution. The Grant Notice may be executed, including execution by facsimile or electronic signature, in one or more counterparts, each

of which will be deemed an original, and all of which together shall be deemed to be one and the same instrument.

Employee  executes,  and  does  not  revoke  as  permitted  by  law,  a  release  in  a  form  reasonably  acceptable  to  the  Company  that  unconditionally  releases,
waives, and fully and forever discharges the Company and its past and current shareholders, directors, officers, employees, and agents from and against any
and  all  claims,  liabilities,  obligations,  covenants,  rights,  demands  and  damages  of  any  nature  whatsoever,  whether  known  or  unknown,  anticipated  or
unanticipated, including without limitation, any claims relating to or arising out of Employee’s employment with the Company, claims arising under the
Age Discrimination in Employment Act of 1967, as amended, Title VII of the Civil Rights Act of 1964, as amended, or the Civil Rights Act of 1991, or
claims arising under the applicable state fair employment laws, but excluding any rights of Employee under any remaining stock option agreements (if any)
or other agreements relating to equity in the Company and Employee’s right to indemnification from the Company in respect of his services as a director,
officer  or  employee  of  the  Company  or  any  of  its  Affiliates.  The  release  shall  also  contain  customary  non-  disparagement  covenants  by  Employee.
Employee’s  right  to  receive  the  Severance  Payment  or  Change  of  Control  Severance  Payment  is  conditioned  upon  Employee’s  performance  of  the
obligations  and  covenants  contained  in  this  Employment  Agreement,  the  Covenants  Agreement  (as  defined  below)  and  any  other  agreement  between
Employee and the Company. In the event of any material breach of any such obligations during or after payment of the Severance Payment or Change of
Control Severance Payment, the Company may cease to make any remaining payments.

6.7.

Notwithstanding anything in this Agreement to the contrary, all payments to be made upon a termination of employment under
this  Agreement  will  only  be  made  upon  a  “separation  from  service”  within  the  meaning  of  Section  409A  of  the  Internal  Revenue  Code  of  1986  (the
“Code”). To the maximum extent permitted under Section 409A of the Code and its corresponding regulations, the cash severance benefits payable under
this  Agreement  are  intended  to  meet  the  requirements  of  the  short-term  deferral  exemption  under  Section  409A  of  the  Code  and  the  “separation  pay
exception”  under  Treas.  Reg.  §1.409A-1(b)(9)(iii).  For  purposes  of  the  application  of  Treas.  Reg.  §  1.409A-1(b)(4)  (or  any  successor  provision),  each
payment in a series of payments to Employee will be deemed a separate payment. In addition, to the extent compliance with the requirements of Treas.
Reg. § 1.409A-3(i)(2) (or any successor provision) is necessary to avoid the application of an additional tax under Section 409A of the Code to payments
due to Employee upon or following his “separation from service”, then notwithstanding any other provision of this Agreement (or any otherwise applicable
plan, policy, agreement or arrangement), any such payments that are otherwise due within six months following the Employee’s “separation from service”
will  be  deferred  without  interest  and  paid  to  Employee  in  a  lump  sum  immediately  following  such  six  month  period.  This  paragraph  should  not  be
construed to prevent the application of Treas. Reg. § 1.409A-1(b)(9)(iii) (or any successor provision) to amounts payable hereunder. For purposes of the
application of Section 409A of the Code, each payment in a series of payments will be deemed a separate payment.

7.

Nonsolicitation;  Confidential  Information,  etc.  Employee  acknowledges  and  agrees  that  Employee  is  bound  by  the  Employee
Nondisclosure and Business Ideas Agreement dated as of Employee’s commencement of employment (the “Covenants Agreement”), which shall continue
in full force and effect.

8.

Indemnification. Subject to the Company’s Articles of Incorporation and By-laws, the Company shall indemnify Employee to the fullest
extent  permitted  by  law  against  all  costs,  expenses,  liabilities  and  losses  (including,  without  limitation,  attorneys’  fees,  judgments,  fines,  penalties,  and
amounts paid in settlement) reasonably incurred by Employee in connection with any “Proceeding” (as defined herein). For the purposes of this Section 8,
a  “Proceeding”  shall  mean  any  action,  suit  or  proceeding,  whether  civil,  criminal,  administrative  or  investigative,  in  which  Employee  is  made,  or  is
threatened to be made, a party to, or a witness in, such action, suit or proceeding by reason of the fact that he is or was an officer, director or employee of
the Company or is or was serving as an officer, director, member, employee, trustee or agent of any other entity at the request of the Company.

Golden Parachute Tax Provisions.

9.1.

In the event that the Company or any of their Affiliates undergoes a Change of Control prior to the time that it (or any Affiliate
that would be treated, together with the Company, as a single corporation under Section 280G of the Code and the regulations thereunder) has stock that is
readily tradeable on an established securities market (within the meaning of the Section 280G of the Code and the regulations thereunder), if the payments
or benefits provided under this Agreement, either alone or together with other payments or benefits which Employee receives or is entitled to receive from
the  Company  or  any  of  its  Affiliates,  would  constitute  an  “excess  parachute  payment”  within  the  meaning  of  Section  280G  of  the  Code,  the  following
provisions shall apply:

or benefits will not be deemed an “excess parachute payment” within the meaning of Section 280G of the Code.

9.1.1.

The Company or any of applicable Affiliates will cooperate in good faith with Employee such that any such payments

9.1.2.

In  the  event  that  any  payments  or  benefits  (whether  payable  pursuant  to  this  Agreement  or  otherwise)  to  Employee
could  be  exempt  from  Section  280G  of  the  Code  if  the  shareholder  approval  requirements  under  Section  280G(b)(5)  of  the  Code  and  the  regulations
thereunder were met, such payments will be conditioned on shareholder approval in accordance with Section 280G(b)(5)(B) of the Code and regulations
thereunder and the Company or any of its applicable Affiliates agrees to use best efforts to seek to obtain such shareholder approval. The actions of the
Company or any of its applicable Affiliates pursuant to this provision are not intended to bind, nor shall be construed as binding, the shareholders of the
Company or any of its applicable Affiliates.

9.2.

In  the  event  that  the  Company  or  any  of  its  applicable  Affiliates  undergoes  a  Change  of  Control  at  such  time  that  it  (or  any
Affiliate that would be treated, together with the Company, as a single corporation under Section 280G of the Code and the regulations thereunder) has
stock that is readily tradeable on an established securities market (within the meaning of the Section 280G of the Code and the regulations thereunder), if
the payments or benefits provided under this Agreement, either alone or together with other payments or benefits which Employee receives or is entitled to
receive from the Company or any of its applicable Affiliates, would constitute an “excess parachute payment” within the meaning of Section 280G of the
Code, Employee shall be entitled to receive (i) an amount limited so that no portion thereof shall fail to be tax deductible under Section 280G of the Code
or subject to an excise tax under Section 4999 of the Code (the “Limited Amount”), or (ii) if the amount otherwise payable hereunder together with other
payments or benefits which Employee receives or is entitled to receive from the Company or any of its applicable Affiliates (without regard to clause (i))
reduced by all taxes applicable thereto (including, for the avoidance of doubt, the excise tax imposed by Section 4999 of the Code) would be greater than
the  Limited  Amount  reduced  by  all  taxes  applicable  thereto,  the  amount  otherwise  payable  hereunder  together  with  other  payments  or  benefits  which
Employee receives or is entitled to receive from the Company or any of its applicable Affiliates.

9.3.

In the event that any payments under this Agreement or otherwise are required to be reduced as described in this Section 9, the
adjustment  will  be  made,  first,  by  reducing  the  cash  severance,  if  any,  due  to  Employee  pursuant  to  Section  6;  second,  if  additional  reductions  are
necessary,  by  reducing  the  payments  due  to  Employee  under  Section  6.5(C)  (Target  Bonus)  and  third,  if  additional  reductions  are  still  necessary,  by
eliminating the accelerated vesting of equity-based awards, starting with those awards for which the amount required to be taken into account under the
Section 280G of the Code rules is the greatest; provided, that in all events, such reductions shall be done in a manner consistent with the requirements of
Section 409A of the Code, to the extent applicable.

10.

Binding  Nature  of  Agreement.  This  Agreement  shall  be  binding  upon  the  Company  and  shall  inure  to  the  benefit  of  the

AMENDMENT #1 TO
AMENDED & RESTATED EXECUTIVE EMPLOYMENT AGREEMENT

Exhibit 10.31

THIS AMENDMENT #1 (this “Amendment”) is made by and between Ocugen, Inc. (the “Company”) and Arun Upadhyay, Ph.D. (“Employee”)

on August 26, 2022.

WHEREAS, the Company and Employee are parties to an Amended & Restated Executive Employment Agreement dated December 16, 2021

(the “Employment Agreement”);

WHEREAS, Section 10.6 of the Employment Agreement provides that the Company and Employee may amend the Employment Agreement by

mutual agreement in writing; and

WHEREAS, the Company and Employee desire to amend the Employment Agreement as set forth herein.

NOW  THEREFORE,  in  consideration  of  these  premises  and  the  mutual  benefits  to  be  derived  herefrom  and  other  good  and  valuable

consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1.    Clause (i) in the definition of “Good Reason” in Section 1 of the Employment Agreement is hereby restated as follows:

(i) Employee delivers written notice to the Company of Employee’s intention to resign from employment due to one or more of such events, which
notice is given within thirty (30) days following the initial occurrence of such event and specifies in reasonable detail the circumstances claimed to
provide the basis for such resignation,

2.    Section 2.1 of the Employment Agreement is hereby restated as follows:

2.1        Company  hereby  employs  Employee  and  Employee  hereby  accepts  employment  as  the  Company’s  Chief  Scientific  Officer,
reporting  to  the  Chief  Executive  Officer  of  the  Company  (the  “CEO”).  Employee  shall  be  a  member  of  the  Executive  Management  Team.
Employee shall be responsible for all duties customarily assigned to the position of Chief Scientific Officer, as well as those other duties and such
other authority as specified by the CEO.

3.    Effective September 1, 2022, Section 4.1 of the Employment Agreement is hereby restated as follows:

4.1        Employee  shall  receive  Base  Compensation  at  the  gross  annual  rate  (without  regard  to  authorized  tax  or  other  legally  required
deductions and withholdings) of $420,000, payable in installments in accordance with the Company’s regular payroll practices in effect from time
to time.

4.    Section 4.2 of the Employment Agreement is hereby restated as follows:

4.2    For each calendar year ending during the Term, Employee will have the opportunity to earn an annual bonus with a target amount
not  less  than  45%  of  the  Employee’s  Base  Compensation  in  effect  at  the  end  of  the  applicable  year  (the  “Target Bonus”).  The  actual  bonus
payable to Employee, if any, may be more or less than the Target Bonus and will be determined by the Compensation Committee of the Board (the
“Compensation Committee”), based on the achievement of corporate and/or personal objectives established by the Compensation Committee and
such other factors as the Compensation Committee may deem relevant. Any annual bonus so awarded shall be paid by February 28th of each year
for the Employee’s performance in the previous year (the “Measuring Year”). To be eligible for an annual bonus, the Employee must be employed
on December 31st of the Measuring Year.

5.    The first two sentences of Section 6.6 of the Employment Agreement are hereby amended to read as follows:

Employee will not be entitled to receive the Severance Payment or Change of Control Severance Payment unless Employee executes a release in a
form reasonably acceptable to the Company (the “Release”) and such release becomes irrevocable within 60 days following termination of his
employment. The Release will unconditionally release, waive, and fully and forever discharge the Company and its past and current shareholders,
directors, officers, employees, and agents from and against any and all claims, liabilities, obligations, covenants, rights, demands and damages of
any nature whatsoever, whether known or unknown, anticipated or unanticipated, including without limitation, any claims relating to or arising out
of Employee’s employment with the Company, claims arising under the Age Discrimination in Employment Act of 1967, as amended, Title VII of
the Civil Rights Act of 1964, as amended, or the Civil Rights Act of 1991, or claims arising under the applicable state fair employment laws, but
excluding  any  vested  rights  of  Employee  under  any  remaining  stock  option  agreements  (if  any)  or  other  agreements  relating  to  equity  in  the
Company and Employee’s right to indemnification from the Company in respect of his services as a director, officer or employee of the Company
or any of its Affiliates.

6.    A paragraph is added to the end of Section 6.6 of the Employment Agreement to read as follows:

Subject to Section 6.7 below, the Severance Payment or Change of Control Severance Payment, as applicable, will begin to be paid as soon as
practicable  following  the  date  the  Release  becomes  irrevocable  (but  not  later  than  70  days  following  Employee’s  termination  of  employment),
provided that the initial payment will include a catch-up payment to cover amounts retroactive to the day immediately following the effective date
of  the  Employee’s  termination  of  employment.  However,  to  the  extent  the  Severance  Payment  or  Change  of  Control  Severance  Payment  is
deferred compensation subject to the requirements of Section 409A of the Code and the 70-day period described above begins in one taxable year
and ends in a second taxable year, such payment will not commence until the second taxable year.

7.    Except as otherwise expressly indicated, the foregoing changes to the Employment Agreement are effective on the date of this Amendment.

8.    Except as set forth in this Amendment, all other terms and conditions of the Employment Agreement shall remain unchanged and in full force

and effect.

9.    This Amendment may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original and all of

which shall constitute the same instrument.

IN WITNESS WHEREOF, the Company has caused this Amendment to be executed by its duly authorized officer, and Employee has executed

this Amendment, in each case on the first date above written.
