ITEM 1. BUSINESS

Business

PART I

Abeona Therapeutics Inc., a Delaware corporation (together with our subsidiaries, “we,” “our,” “Abeona” or the “Company”), is a clinical-stage biopharmaceutical company
developing  cell  and  gene  therapies  for  life-threatening  diseases.  Our  lead  clinical  program  is  EB-101,  an  autologous,  engineered  cell  therapy  currently  in  development  for
recessive dystrophic epidermolysis bullosa (“RDEB”). EB-101 has been granted Orphan Drug and Rare Pediatric Disease (“RPD”) designations by the U.S. Food and Drug
Administration (“FDA”) and Orphan Drug Designation by the European Medicines Agency (“EMA”).

We plan to continue development of AAV-based gene therapies designed to treat ophthalmic diseases with high unmet medical need using the novel AIM™ capsid platform that
we have exclusively licensed from the University of North Carolina at Chapel Hill (“UNC”), and internal AAV vector research programs. Abeona’s novel, next-generation AAV
capsids are being evaluated to improve tropism profiles for a variety of devastating diseases.

Our Mission and Strategy

Abeona is a fully-integrated cell and gene therapy company featuring research and clinical development programs, in-house manufacturing facilities, and scientific and clinical
leadership. Our mission is to create, develop, manufacture, and deliver cell and gene therapies to transform the lives of people impacted by life-threatening diseases. In 2022,
we continued to make progress toward fulfilling our goal of harnessing the promise of genetic medicine and redefining the standard of care through cell and gene therapies. In
November 2022, we announced positive topline data from the VIITAL™ Phase 3 study evaluating the efficacy, safety and tolerability of EB-101.

We partner with leading academic researchers, patient advocacy organizations, caregivers and other biotechnology companies to develop therapies that address the underlying
cause of a broad spectrum of rare genetic diseases for which no effective treatment options exist today.

Our strategy consists of:

Advancing and Commercializing our Late-Stage Clinical Cell and Gene Therapy Programs with a Focus on Life-Threatening Diseases.

Through our cell and gene therapy expertise in research and development, we believe we are positioned to introduce efficacious and safe therapeutics to transform the
standard of care in devastating diseases and establish our leadership position in the field. We intend to commercialize our assets either by ourselves or through strategic
partnerships, subject to FDA approval.

Developing Novel In-Vivo Gene Therapies Using AIM™ Capsid Technology.

We are researching and developing AAV-based gene therapy using our novel capsids developed from the AIM™ Capsid Technology Platform and additional Company-
invented AAV  capsids. We  plan  to  continue  to  develop  our  chimeric AAV  capsids  capable  of  improved  tissue  targeting  for  various  indications  and  potentially  evading
immunity to wildtype AAV vectors.

Leveraging our Leadership Position in Commercial-Scale Cell and Gene Therapy Manufacturing.

We established current Good Manufacturing Practice (“cGMP”), clinical-scale manufacturing capabilities for engineered cell therapy and AAV-based gene therapies in our
state-of-the-art  Cleveland,  Ohio  facility.  We  believe  that  our  platform  provides  us  with  distinct  advantages,  including  flexibility,  scale,  reliability,  and  the  potential  for
reduced development risk, reduced cost, and faster times to market. We have focused on establishing internal Chemistry, Manufacturing and Controls (“CMC”) capabilities
that drive value for our organization through process development, assay development and manufacturing. We have also deployed robust quality systems governing all
aspects of product lifecycle from preclinical through commercial stage.

Establishing Additional Cell and Gene Therapy Franchises and Adjacencies through In-Licensing and Strategic Partnerships.

We  seek  to  be  the  partner  of  choice  in  cell  and  gene  therapy  treatment  and  have  closely  collaborated  with  leading  academic  institutions,  key  opinion  leaders,  patient
foundations, and industry partners to accelerate research and development, understand the needs of patients and their families, and generate novel intellectual property.

Maintaining and Growing our IP Portfolio.

We  seek  patent  rights  for  various  aspects  of  our  programs,  including  vector  engineering  and  construct  design,  our  production  process,  and  all  features  of  our  clinical
products including composition of matter and method of administration and delivery. We expect to continue to expand our intellectual property portfolio by aggressively
seeking patent rights for promising aspects of our product engine and product candidates.

Developing Next-Generation Cell and Gene Therapy

EB-101 for the Treatment of RDEB

Disease Overview

RDEB belongs to a broad group of genetic skin disorders known as epidermolysis bullosa. Patients with RDEB have a defect in the COL7A1 gene, resulting in the inability to
produce Type VII collagen, which plays a vital role in anchoring the skin’s dermal and epidermal layers.

As a result of the genetic defect, RDEB patients have fragile skin, which can easily damage to produce open and blistering wounds, disfiguring scars throughout the body, fused
fingers and toes, limits in range of motion at joints (e.g., arms and legs), and an abnormal narrowing of the esophagus. Long-term RDEB patients can suffer from anemia, are at
high risk of developing aggressive squamous cell carcinomas, infections, and premature death. The most severe patients are approximately 20 times more likely to die by 30
years of age than the general population.

Similar to other rare diseases, the incidence and prevalence of RDEB are not well defined. Incidence of 0.2 to 3.05 per million births and prevalence of 0.14 to 1.35 per million
people  have  been  observed  across  different  geographies,  primarily  estimated  by  limited  population  analyses  of  clinical  databases  or  registries  (Eichstadt  et  al.;  Clinical,
Cosmetic and Investigational Dermatology, 2019). Using genetic modeling of COL7A1 variants, which is believed to cause RDEB, Stanford University estimated the incidence
of RDEB to be approximately 63 per million births, and prevalence could be up to 3,850 patients in the U.S., whose wounds may benefit from COL7A1-mediated treatments
such as EB-101.

RDEB patients have, on average, 11 active wounds on their bodies, with the majority > 20 cm2 (Stanford University; Solis, D., et al., 2017). In 2020, a survey of RDEB patients
reported that approximately 60% have active wounds covering greater than 30% of their bodies (Bruckner et al.; Orphanet Journal of Rare Diseases, 2020). Wounds covering
up to approximately 80% of body surface area have been recorded in some EB patients (Hirsch et al.; Nature Research, 2017).

We expect EB-101 could be a treatment option for toughest to treat RDEB wounds. EB-101 has shown durable healing and associated pain reduction in our VIITAL™ phase 3
trial in large and/or chronic wounds that carry the highest burden, including the need for frequent dressing changes, pain, pruritus, risk of infection, and developing skin cancer.

Current Management of RDEB

At present, there are no approved treatments for RDEB in the U.S. or Europe.

Wound management currently consists of time and labor-intensive supportive care to limit contamination and infection, and reduction in mechanical forces that produce new
blisters. Care usually includes treatment of new blisters by lancing and draining. Wounds are then dressed with a non-adherent material, covered with padding for stability and
protection, and secured with an elastic wrap for integrity. The annual costs of wound dressings alone for an RDEB patient can amount to as high as $996,000 per year.

RDEB patients also have periodic surgeries to relieve disease related issues such as narrowing of their esophagus, fusing of fingers, and corneal abrasions.

Program Status and Positive Topline Data

EB-101  is  an  autologous,  engineered  cell  therapy  in  which  a  functioning  COL7A1  gene  is  inserted  into  a  patient’s  own  skin  cells  (keratinocytes)  using  a  retrovirus.  The
keratinocytes are then transplanted back to the patient to restore Type VII collagen expression and skin function.

Results  from  a  completed  Phase  ½  study  that  enrolled  7  patients  with  large  and  chronic  RDEB  wounds  at  Stanford  University  showed  that  EB-101  was  well-tolerated  and
resulted in significant and durable wound healing (Siprashvili, Z., et al., 2016), with up to eight years of follow-up (So. Y, Nazaraoff, et al., Orphanet Journal Rare Disease
2022). To date, there have been no reported serious adverse events.

On November 3, 2022, we announced positive topline data from VIITAL™ study. The pivotal Phase 3 VIITAL™ study evaluated the efficacy, safety and tolerability of EB-101
in 43 large chronic wound pairs in 11 subjects with RDEB. The large chronic wounds randomized and treated in VIITAL™ measured greater than 20 cm2 of surface area and
had remained open for a minimum of six months and a maximum of 21 years (mean 6.2 years). The co-primary endpoints of the study were: (1) the proportion of RDEB wound
sites  with  greater  than  or  equal  to  50%  healing  from  baseline,  comparing  randomized  treated  with  matched  untreated  (control)  wound  sites  at  the  six-month  timepoint,  as
determined by direct investigator assessment; and (2) pain reduction associated with wound dressing change assessed by the mean differences in scores of the Wong-Baker
FACES scale between randomized treated and matched untreated (control) wounds at the six-month timepoint.

The VIITAL™ study met its two co-primary efficacy endpoints demonstrating statistically significant, clinically meaningful improvements in wound healing and pain reduction
in large chronic RDEB wounds. EB-101 was shown to be well-tolerated with no serious treatment-related adverse events observed, consistent with past clinical experience.
There were no deaths or instances of positive replication-competent retrovirus results, and no systemic immunologic responses were reported during the study, as well as no
squamous cell carcinoma at treatment sites after application of EB-101. Two subjects reported at least one serious adverse event unrelated to EB-101. Four subjects reported
related treatment emergent adverse events, including procedural pain, muscle spasms and pruritis. Infections unrelated to EB-101 were observed in eight patients.

Based  on  these  positive  topline  results,  we  intend  to  submit  a  Biologics  License  Application  (“BLA”)  for  EB-101  to  the  FDA  by  mid-2023.  EB-101  has  been  granted
Regenerative Medicine Advanced Therapy (“RMAT”), Breakthrough Therapy, Orphan Drug and RPD designations by the by the FDA as well as Orphan Drug designation by
the EMA.

Among the potential benefits of Orphan Drug designation are a potential seven years of market exclusivity following FDA approval, potentially preventing FDA approval of
another  product  deemed  to  be  the  same  as  the  approved  product  for  the  same  indication,  waiver  of  application  fees,  and  tax  credits  for  qualified  clinical  testing  expenses
conducted after orphan designation is received. A sponsor who receives an approval for a BLA with RPD designation may qualify for a Priority Review Voucher (“PRV”),
subject to final determination by the FDA. A PRV may be used to receive expedited review of a subsequent marketing application for a different product or sold to another
company.

We have continued to prepare our cGMP commercial facility in Cleveland for manufacturing EB-101 to support our planned BLA filing. EB-101 study drug product for all our
VIITAL™ study participants has been manufactured at our Cleveland facility.

ABO-503 for the treatment of X-linked Retinoschisis (“XLRS”).

Disease Overview and Program Overview

XLRS is a rare, monogenic retinal disease that results in the irreversible loss of photoreceptor cells and severe visual impairment. XLRS is caused by mutations in the RS1
protein, which is normally secreted by retinal photoreceptors and bipolar neurons and functions to mediate cell-cell adhesion. XLRS is characterized by abnormal splitting of
the layers of the retina, resulting in poor visual acuity, which can progress to legal blindness. The incidence of XLRS is estimated to be between 1 in 5,000 and 1 in 20,000 in
males, with an estimated prevalence of 35,000 in the United States and Europe combined. There are currently no disease modifying therapies approved for XLRS, but because
the genetics of the disease are well understood, early intervention via gene therapy has significant potential to reverse or stabilize disease progression at early stages and prevent
vision loss.

ABO-503,  composed  of  a  functional  human  RS1  packaged  in  the  novel AIM™  capsid AAV204,  has  shown  preclinical  efficacy  following  delivery  to  the  retina  in  a  mouse
model of XLRS. Preclinical studies have demonstrated robust RS1 expression in the retina, improved cone photoreceptor density and overall photoreceptor cell survival, as
well as a restoration of outer retina architecture. We submitted a pre-IND meeting request with the FDA in March 2023.

ABO-504 for the Treatment of Stargardt Disease

Disease Overview and Program Overview

Autosomal recessive Stargardt disease, the most common form of juvenile macular degeneration with estimated incidence of 1 in 8,000 to 10,000 people, causes vision loss in
children  and  young  adults.  The  most  common  form  of  Stargardt  disease  is  caused  by  mutations  in  the  ABCA4  gene,  which  prevent  removal  of  toxic  compounds  from
photoreceptor cells that results in photoreceptor cell death and progressive vision loss. There are currently no FDA approved treatments available, and to date, development of
investigational gene modifying therapies has remained challenging in part due to the large size of the ABCA4 gene, which exceeds the encapsidation capacity of a single AAV
vector.

Abeona’s internal research and development team developed ABO-504, which is designed to efficiently reconstitute the full-length ABCA4 gene by implementing a dual AAV
vector strategy using the Cre-LoxP recombinase system. In May 2021, at the Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting, Abeona reported
preclinical data demonstrating the ability of the dual AAV vector system to produce full length ABCA4 protein in cell culture. Recent proof-of-concept studies have extended
these  findings  by  showing  expression  of  ABCA4  mRNA  and  full-length  ABCA4  protein  in  the  retina  of  subretinally  dosed  abca4-/-  knockout  mice,  at  levels  similar  to
endogenous ABCA4 in wild-type animals.

ABO-505 for the Treatment of Autosomal Dominant Optic Atrophy (“ADOA”)

Disease Overview and Program Overview

ADOA, a form of hereditary vision loss associated with RGC death, is predominantly caused by mutations in the Opa1 gene. Opa1, a dynamin-related GTPase, acts to stabilize
the inner mitochondrial membrane and acts in mitochondrial fusion and inner membrane remodeling. Mutant phenotypes present with a progressive loss of RGCs that results in
optic nerve degeneration and legal blindness with a loss of visual acuity, optic disc pallor, and color vision deficits. ADOA affects approximately 1 in 30,000 people worldwide.
Currently, there is no approved treatment for people living with ADOA.

ABO-505 is designed to express a functional copy of human Opa1 in the retina following para-retinal injection. ABO-505 aims to take advantage of the robust optic nerve and
retinal ganglion cell (RGC) transduction ability of AAV204 to deliver its genetic payload to the cells most affected by ADOA. Preclinical studies have confirmed expression of
Opa1 in both cell culture and the retinas of dosed wild-type and disease model animals. Initial efficacy results suggest an improvement in retinal signaling to the brain, and
improved visual acuity in treated mutant mice.

New preclinical data with ABO-503, ABO-504 and ABO-505 have been submitted for presentation at a future medical meeting in the second quarter of 2023.

Gene Therapy Treatments anchored in AIM™ Vector Platform

In 2016, we licensed a library of novel AAV capsids from UNC. The AIM™ vector system is a platform of AAV capsids capable of widespread central nervous system gene
transfer and can be used to confer high transduction efficiency for various therapeutic indications. In partnership with academic institutions, our own scientific research teams
have identified vectors within the AIM™ capsid library showing strong potential to successfully target and reach the central nervous system as well as ocular, lung, muscle,
liver, and other tissues. Based on continuing research by Abeona and our research partners, we have observed improvements in gene delivery to specific tissues compared to
currently available AAV technology. We believe AIM™ vectors also have the potential for redosing subjects who previously received certain AAV gene therapy or subjects who
have pre-existing antibodies to naturally occurring AAV serotypes.

Strategic Licensing Agreements

We  have  out-licensed  certain  clinical  and  research  programs,  including  for  the  treatment  of  Sanfilippo  syndrome  type  A  (MPS  IIIA)  to  Ultragenyx  Pharmaceutical  Inc.
(“Ultragenyx”),  and  for  CLN1  disease  (infantile  Batten  disease)  and  Rett  syndrome  to  Taysha  Gene  Therapies,  Inc.  (“Taysha”).  Under  the  terms  of  our  agreement  with

Leveraging Leadership Position in Commercial-Scale Cell and Gene-Therapy Manufacturing

We have established a cGMP manufacturing facility, the Elisa Linton Center located in Cleveland, Ohio, which enables us to enhance supply chain control, establish tighter
quality  control  testing,  increase  supply  capacity,  reduce  production  costs  and  gain  manufacturing  efficiency  for  clinical  trials  related  to  our  product  candidates  and  ensure
commercial demand is met in the event our therapies receive marketing approval. Our facility is led by a team of highly-skilled production, process/assay development and QC
scientists with expertise in cell and gene therapy, particularly in cell culture, upstream manufacturing, downstream purification, assay development and wet lab techniques.

We have completed our 16,000+ square foot manufacturing build-out in Cleveland, Ohio. The first phase, completed in 2018, was a 6,000 square foot state-of-the-art cGMP
production facility for the manufacturing of cell and gene therapies. The facility is designed to initially manufacture clinical drug products with later intent of manufacturing
commercial  grade  cGMP  drug  product. The  second  phase,  completed  in  2019,  was  the  completion  of  an  additional  8,000  square  feet  of  state-of-the-art  laboratory  space  to
support  our  expanding  quality  control,  process  development,  and  assay  development  teams.  The  second  phase  also  included  nearly  2,000  square  feet  of  cGMP  Inventory
Control space.

We have advanced our in-house manufacturing capabilities for EB-101. The product is manufactured as a multilayer cellular sheet containing corrected keratinocytes that is
fastened  to  a  petrolatum  gauze  backing  with  surgical  hemoclips.  Engineered  sheets  are  applied  over  wound  areas,  where  they  are  expected  to  produce  keratinocytes  with
functioning Type VII collagen, providing immediate wound coverage and allowing for long-term wound healing. A key component to the EB-101 drug product manufacturing
process  is  the  retroviral  vector,  which  delivers  the  functional  copy  of  the  Collagen  VII  Alpha  1  cDNA  to  the  autologous  patient  cells.  Initially  developed  at  the  Indiana
University  Vector  Production  Facility,  we  have  transferred  the  cGMP  manufacturing  process  for  the  LZRSE-Col7A1  retroviral  vector  to  our  Cleveland  facility  and  have
produced three cGMP lots for analytical and clinical comparability. We have also created and characterized a cGMP master cell bank and a working cell bank to support the
cGMP production of the retroviral vector.

We  have  established AAV  vector  manufacturing  capabilities  that  use  the  triple  plasmid  transient  transfection  method.  We  insert,  or  transfect,  many  copies  of  three  DNA
plasmids encoding the specific therapeutic gene sequence, or transgene, the capsid coding sequence, and helper sequences into AAV-293 cells using a serum-free, suspension-
based bioreactor vector production technology. During an incubation period following transfection, each cell produces AAV vectors through biosynthesis using the cells’ natural
machinery. At the end of the incubation period, the newly generated AAV vectors are harvested, purified and filtered in a multi-step process. We continue to maintain focus on
cGMP compliance and ensuring adequate supply to support our future clinical activity.

We  have  established  and  maintained  strong  and  collaborative  relationships  with  third-party  companies  specializing  in  the  testing  of  cell  and  gene  therapy  material  to
complement our process and assay development needs.

We  have  made  significant  investments  in  developing  optimized  manufacturing  processes  and  believe  that  our  processes  and  methods  developed  to  date  provide  a
comprehensive manufacturing process for EB-101 and AAV-based vector therapies, including:

● sufficient scale to support commercial manufacturing requirements for EB-101
● processes related to biopsy, cell collection, storage and transportation as part of manufacturing for EB-101
● processes related to product release testing for EB-101
● processes related to the manufacture and release testing of retroviral supernatant
● establishing transportation and packaging processes and materials for finished EB-101 product
● proprietary AAV vector manufacturing processes and techniques that produce a highly purified product candidate
● AAV serum-free suspension technology that is readily scalable
● multiple assays to accurately characterize our process and the AAV vectors we produce
● a series of purification processes, which may be adapted and customized for multiple different AAV capsids, with a goal of higher concentrations of active vectors, and

that are essentially free of empty capsids.

We believe that these improvements will enable us to develop best-in-class, next-generation cell and gene therapy products. As we look to commercialize EB-101 (subject to
FDA  approval),  we  are  working  towards  filing  a  BLA  to  support  commercial  manufacturing  of  EB-101  from  our  Cleveland  facility.  Based  on  feedback  from  the  FDA,  we
believe that we have alignment with the FDA on the CMC requirements for EB-101, including characterization and validation plans.

Maintain Strong Intellectual Property Protection

We strive to protect our commercially important proprietary technology, inventions, and know-how, including by seeking, maintaining, and defending patent rights, both for
inventions developed internally and for inventions licensed from third parties. We also rely on trade secrets and know-how relating to our proprietary technology platforms,
continuing technological innovation, and in-licensing opportunities to develop, strengthen and maintain our position in the field of cell and gene therapy. We may also rely on
the additional protections afforded by data exclusivity (currently 12 years for biologics), other market exclusivities such as orphan drug exclusivity, and patent term extensions,
where applicable.

Our success may depend in part on our ability to obtain and maintain patent and other protections for commercially important technology, inventions and know-how related to
our  business;  defend  and  enforce  our  patents;  preserve  the  confidentiality  of  our  trade  secrets;  and  operate  without  infringing  the  valid  enforceable  patents  and  intellectual
property rights of third parties. Our ability to stop third parties from making, having made, using, selling, offering to sell, or importing our products may depend on the extent to
which we have rights under valid and enforceable licenses, patents or trade secrets that cover these activities. In some cases, these rights may need to be enforced by third-party
licensors. With respect to both licensed and company-owned intellectual property, we may not be granted patents with respect to any of our pending patent applications or with
respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future will be
commercially useful in protecting our commercial products and methods of manufacturing the same.

We are actively seeking U.S. and international patent protection for a variety of technologies, including the following: research tools and methods, methods for transferring
genetic  material  into  cells,  AAV-based  biological  products,  methods  of  designing  novel  AAV  constructs,  methods  for  treating  diseases  of  interest  and  methods  for
manufacturing, packaging, and transporting our product candidates. We also intend to seek patent protection or rely upon trade secret rights to protect other technologies that
may be used to discover and validate targets and that may be used to identify and develop novel biological products. We seek protection, in part, through confidentiality and
proprietary information agreements. We are a party to various license agreements that give us rights to use specific technologies in our research and development, and future
commercialization.

U.S. Biologic Products Development Process

In  the  United  States,  the  FDA  regulates  biologic  products  including  gene  therapy  products  under  the  Federal  Food,  Drug,  and  Cosmetic Act  (“FDCA”),  the  Public  Health
Service  Act  (“PHSA”),  and  regulations  implementing  these  laws.  The  FDCA,  PHSA  and  their  corresponding  regulations  govern,  among  other  things,  the  testing,
manufacturing, safety, efficacy, labeling, packaging, storage, record keeping, distribution, advertising, and promotion of biologic products. Applications to the FDA are required
before conducting human clinical testing of biologic products. FDA approval also must be obtained before marketing of biologic products. Gene therapy studies may also need
to  comply  with  the  National  Institutes  of  Health  (“NIH”)  Guidelines  for  Research  Involving  Recombinant  or  Synthetic  Nucleic Acid  Molecules  (“NIH  Guidelines”),  which
includes additional requirements, such as the review and approval of the study by an Institutional Biosafety Committee.

Within the FDA, the Center for Biologics Evaluation and Research (“CBER”) regulates gene therapy products. Within CBER, the review of gene therapy and related products
is  consolidated  in  the  Office  of  Tissues  and  Advanced  Therapies  (“OTAT”)  and  the  FDA  has  established  the  Cellular,  Tissue  and  Gene  Therapies  Advisory  Committee
(“CTGTAC”),  a  panel  of  medical  and  scientific  experts  and  consumer  representatives,  to  advise  CBER  on  its  reviews.  The  FDA  has  issued  a  growing  body  of  guidance
documents on CMC, clinical investigations and other areas of gene therapy development, all of which are intended to facilitate the industry’s development of gene therapy
products.

The process required by the FDA before a biologic product candidate may be marketed in the United States generally involves the following:

● completion  of  preclinical  laboratory  tests  and  in  vivo  studies  in  accordance  with  the  FDA’s  current  Good  Laboratory  Practice  (“GLP”)  regulations  and  applicable

requirements for the humane use of laboratory animals or other applicable regulations;

● submission to the FDA of an application for an IND, which allows human clinical trials to begin unless the FDA objects within 30 days;
● approval by an independent institutional review board (“IRB”), reviewing each clinical site before each clinical trial may be initiated;
● performance  of  adequate  and  well-controlled  human  clinical  trials  according  to  the  FDA’s  Good  Clinical  Practice  (“GCP”)  regulations,  and  any  additional
requirements for the protection of human research subjects and their health information, to establish the safety and efficacy of the proposed biologic product candidate
for its intended use;

● development of manufacturing processes to ensure the product candidate’s identity, strength, quality, purity, and potency;
● preparation and submission to the FDA of a BLA for marketing approval that includes substantial evidence of safety, purity and potency from results of nonclinical

testing and clinical trials;

● satisfactory  completion  of  an  FDA  pre-approval  inspection  of  the  manufacturing  facility  or  facilities  where  the  biologic  product  candidate  is  produced  to  assess
compliance  with  cGMP  and  to  assure  that  the  facilities,  methods  and  controls  are  adequate  to  preserve  the  biologic  product  candidate’s  identity,  safety,  strength,
quality, potency and purity;

● potential FDA audit of the nonclinical and clinical trial sites that generated the data in support of the BLA; and
● payment  of  user  fees  and  the  FDA  review  and  approval,  or  licensure,  of  the  BLA.  BLA  application  fees  for  products  designated  as  orphan  drugs  by  the  FDA  are

waived.

Before testing any biologic product candidate on humans, including a gene therapy product candidate, the product candidate must undergo preclinical testing. Preclinical tests,
also referred to as nonclinical studies, include laboratory evaluations of product chemistry, toxicity, and formulation, as well as in vivo studies to assess the potential safety and
activity of the product candidate. The conduct of the preclinical tests must comply with federal regulations and requirements including GLPs.

If a gene therapy trial is conducted at, or sponsored by, institutions receiving NIH funding for recombinant DNA research, the study must also comply with the NIH Guidelines.
Compliance with the NIH Guidelines is mandatory for investigators at institutions receiving NIH funds for research involving recombinant DNA. However, many companies
and other institutions, not otherwise subject to the NIH Guidelines, voluntarily follow them.

10

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The clinical trial sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a
proposed clinical protocol, to the FDA as part of the IND. Some preclinical testing may continue even after the IND is submitted. The IND automatically becomes effective 30
days after receipt by the FDA, unless the FDA places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns
before the clinical trial can begin. The FDA also may impose clinical holds on a biologic product candidate at any time before or during clinical trials due to safety concerns or
non-compliance. If the FDA imposes a clinical hold, trials may not commence or recommence without FDA authorization and then only under terms authorized by the FDA.

Human clinical trials under an IND

Clinical trials involve the administration of the biologic product candidate to healthy volunteers or patients under the supervision of qualified investigators, which generally are
physicians not employed by, or under the control of, the trial sponsor. 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 clinical trial, dosing procedures,
subject selection and exclusion criteria and the parameters to be used to monitor subject safety, including stopping rules that assure a clinical trial will be stopped if certain
adverse  events  should  occur.  Each  protocol  and  any  amendments  to  the  protocol  must  be  submitted  to  the  FDA  as  part  of  the  IND.  Clinical  trials  must  be  conducted  and
monitored in accordance with the FDA’s regulations comprising the GCP requirements, including the requirement that all research subjects provide informed consent.

Further,  each  clinical  trial  must  be  reviewed  and  approved  by  an  IRB  at  or  servicing  each  institution  at  which  the  clinical  trial  will  be  conducted. An  IRB  is  charged  with
protecting  the  welfare  and  rights  of  trial  participants  and  considers  items  such  as  whether  the  risks  to  individuals  participating  in  the  clinical  trials  are  minimized  and  are
reasonable in relation to anticipated benefits. The IRB also approves communications to study subjects before a study commences at that site and the form and content of the
informed consent that must be signed by each clinical trial subject, or his or her legal representative, and must monitor the clinical trial until completed. Clinical trials involving
recombinant DNA also must be reviewed by an institutional biosafety committee (“IBC”), a local institutional committee that reviews and oversees basic and clinical research
that utilizes recombinant DNA at that institution. The IBC assesses the safety of the research and identifies any potential risk to public health or the environment.

Information about certain clinical trials, including a description of the study and study results, must be submitted within specific timeframes to NIH for public dissemination on
their 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.

Investigational biologics 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.

Human clinical trials typically are conducted in three sequential phases that may overlap or be combined:

● Phase  1:  The  biologic  product  candidate  initially  is  introduced  into  healthy  human  subjects  and  tested  for  safety,  dosage  tolerance,  absorption,  metabolism,
distribution, excretion and, if possible, to gain an early understanding of its effectiveness. In the case of some product candidates for severe or life-threatening diseases,
especially when the product candidate may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.

● Phase 2: The biologic product candidate is evaluated in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the

efficacy of the product candidate for specific targeted diseases and to determine dosage tolerance, optimal dosage and dosing schedule.

● Phase  3:  The  biologic  product  candidate  is  administered  to  an  expanded  patient  population  at  geographically  dispersed  clinical  trial  sites  in  adequate  and  well-
controlled  clinical  trials  to  generate  sufficient  data  to  statistically  confirm  the  efficacy  and  safety  of  the  product  for  approval.  These  clinical  trials  are  intended  to
establish the overall risk/benefit ratio of the product candidate and provide an adequate basis for product labeling. Typically, two Phase 3 trials are required by the
FDA for product approval. Under some limited circumstances, however, the FDA may approve a BLA based upon a single Phase 3 clinical study plus confirmatory
evidence or a single large multicenter trial without confirmatory evidence.

11

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Additional kinds of data may also help to support a BLA, such as patient experience data. Real world evidence may also support a BLA, and, for appropriate indications sought
through supplemental BLAs, data summaries may provide marketing application support. For genetically targeted products and variant protein targeted products intended to
address an unmet medical need in one or more patient subgroups with a serious or life threatening rare disease or condition, the FDA may allow a sponsor to rely upon data and
information  previously  developed  by  the  sponsor  or  for  which  the  sponsor  has  a  right  of  reference,  that  was  submitted  previously  to  support  an  approved  application  for  a
product that incorporates or utilizes the same or similar genetically targeted technology or a product that is the same or utilizes the same variant protein targeted drug as the
product that is the subject of the application.

Post-approval clinical trials, sometimes referred to as Phase IV clinical trials, may be conducted or may be required by FDA after initial approval. These clinical trials are used
to gain additional experience from the treatment of patients in the intended therapeutic indication, particularly for long-term safety follow-up.

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, IRBs, IBCs, and the investigators for serious and unexpected adverse events; any findings from other trials,
in vivo laboratory tests or in vitro testing that suggest a significant risk for human subjects; any clinically important increase in the rate of a serious suspected adverse reaction
over that listed in the protocol or investigator brochure, or other safety information. 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.

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

Additional regulation for gene therapy clinical trials

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 at each of the above stages of development and 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 efficacy in support of an IND or BLA application; and long term patient and clinical study subject follow up and reporting requirements. The FDA has also
issued draft guidance specific to the development of gene therapy products for neurodegenerative diseases as such products may face special challenges related to CMCs and
clinical and preclinical development, due to the nature of the products and potential patient population (e.g., children), the heterogeneity of neurodegenerative disorders, the
route of administration, the volume of the product that can be administered, the delivery device, and the study population size.

Compliance with cGMP requirements

Manufacturers of biologics must comply with applicable cGMP regulations for both clinical and commercial supply. Manufacturers and others involved in the manufacture and
distribution  of  such  products  at  the  commercial  stage  also  must  register  their  establishments  with  the  FDA  and  certain  state  agencies  and  list  the  manufactured  products.
Recently,  the  information  that  must  be  submitted  to  FDA  regarding  manufactured  products  was  expanded  through  the  Coronavirus Aid,  Relief,  and  Economic  Security,  or
CARES, Act  to  include  the  volume  of  drugs  produced  during  the  prior  year.  Both  domestic  and  foreign  manufacturing  establishments  must  register  and  provide  additional
information  to  the  FDA  upon  their  initial  participation  in  the  manufacturing  process.  Establishments  may  be  subject  to  periodic,  unannounced  inspections  by  government
authorities  to  ensure  compliance  with  cGMP  requirements  and  other  laws.  Discovery  of  problems  may  result  in  a  government  entity  placing  restrictions  on  a  product,
manufacturer,  or  holder  of  an  approved  BLA,  and  may  extend  to  requiring  withdrawal  of  the  product  from  the  market. The  FDA  will  not  approve  an  application  unless  it
determines that the manufacturing processes and facilities comply with cGMP requirements and are adequate to assure consistent production of the product within required
specification.

12

 
 
 
 
 
 
 
 
 
 
 
Concurrent with clinical trials, companies usually complete additional preclinical studies and must also develop additional information about the physical characteristics of the
biologic  product  candidate  as  well  as  finalize  a  process  for  manufacturing  the  product  candidate  in  commercial  quantities  in  accordance  with  cGMP  requirements. To  help
reduce  the  risk  of  the  introduction  of  adventitious  agents  or  of  causing  other  adverse  events  with  the  use  of  biologic  products,  the  PHSA  emphasizes  the  importance  of
manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the
product candidate and, among other requirements, the sponsor must develop methods for testing the identity, strength, quality, potency and purity of the final biologic product.
Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the biologic product candidate does not undergo
unacceptable deterioration over its shelf life.

U.S. review and approval processes

The results of the preclinical tests and clinical trials, together with detailed information relating to the product’s CMC and proposed labeling, among other things, are submitted
to the FDA as part of a BLA requesting approval to market the product for one or more indications.

For gene therapies, selecting patients with applicable genetic defects is a necessary condition to effective treatment. For the therapies we are currently developing, we believe
that diagnoses based on symptoms, in conjunction with existing genetic tests developed and administered by laboratories certified under the Clinical Laboratory Improvement
Amendments, are sufficient to select appropriate patients and will be permitted by the FDA. For future therapies, however, it may be necessary to use FDA-cleared or FDA-
approved  diagnostic  tests  to  select  patients  or  to  assure  the  safe  and  effective  use  of  therapies  in  appropriate  patients.  The  FDA  refers  to  such  tests  as  in  vitro  companion
diagnostic devices and the combination of the in vitro companion diagnostic device and the therapeutic would be considered to be a combination product.

The use of the two products together must be shown to be safe and effective for the proposed intended use and the labeling of the two products must reflect their combined use.
In some cases, the device component may require a separate premarket submission; for example, when the device component is intended for use with multiple drug products.
Sponsors  of  clinical  studies  using  investigational  devices  are  required  to  comply  with  FDA’s  investigational  device  exemption  regulations.  Once  approved  or  cleared,  the
sponsor of the device component submission (or the combination product submission, if both components are covered by one premarket submission) would need to comply
with FDA’s post-market device requirements, including establishment registration, device listing, device labeling, unique device identifier, quality system regulation, medical
device reporting, and reporting of corrections and removals requirements.

The FDA has a policy position that, when safe and effective use of a therapeutic product depends on a diagnostic device, the FDA generally will require approval or clearance
of the diagnostic device at the same time that the FDA approves the therapeutic product. The type of premarket submission required for a companion diagnostic device will
depend  on  the  FDA  classification  of  the  device.  A  premarket  approval,  or  PMA,  application  is  required  for  high  risk  devices  classified  as  Class  III;  a  510(k)  premarket
notification is required for moderate risk devices classified as Class II; and a de novo request may be used for novel devices not previously classified by the FDA that are low or
moderate risk.

The FDA may, however, approve a therapeutic product without the concurrent approval or clearance of a diagnostic device when the therapeutic product is intended to treat
serious and life-threatening conditions for which no alternative exists and the FDA determines that the benefits from the use of the drug/biologic outweigh the risks from the
lack of an approved/cleared companion diagnostic. The FDA would also consider whether additional protections, such as risk evaluation and mitigation strategies, or REMS, or
post-approval requirements, are necessary. At this point, it is unclear how the FDA will apply this policy to our gene therapy candidates. Should the FDA deem genetic tests
used for selecting appropriate patients for our therapies to be in vitro companion diagnostics requiring FDA clearance or approval, we may face significant delays or obstacles
in obtaining approval for a BLA. In addition, under the Pediatric Research Equity Act (“PREA”), a BLA or supplement to a BLA must contain data to assess the safety and
effectiveness of the biologic product candidate for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric
subpopulation for which the product candidate is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers. Unless otherwise required by
regulation, PREA does not apply to any biologic product candidate for an indication for which orphan designation has been granted.

13

 
 
 
 
 
 
 
 
 
Under  the  Prescription  Drug  User  Fee Act  ,  as  amended  (“PDUFA”),  each  BLA  must  be  accompanied  by  a  substantial  user  fee  that  must  be  paid  at  the  time  of  the  first
submission of the application, even if the application is being submitted on a rolling basis. The FDA adjusts the PDUFA user fees on an annual basis. Fee waivers or reductions
are available in certain circumstances, including a waiver of the application fee for the first application filed by a small business. Additionally, no user fees are assessed on
BLAs for product candidates designated as orphan drugs, unless the product candidate also includes a non-orphan indication.

The FDA reviews a BLA within 60 days of submission to determine if it is substantially complete before the agency accepts it for filing. The FDA may refuse to accept for
filing  any  BLA  that  it  deems  incomplete  or  not  properly  reviewable  at  the  time  of  submission  and  may  request  additional  information.  In  that  event,  the  BLA  must  be
resubmitted with the additional information. The resubmitted application also is 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 of the BLA.

The FDA reviews the BLA to determine, among other things, whether the proposed product candidate is safe and potent, or effective, for its intended use, has an acceptable
purity  profile  and  whether  the  product  candidate  is  being  manufactured  in  accordance  with  cGMP  to  assure  and  preserve  the  product  candidate’s  identity,  safety,  strength,
quality, potency, and purity. The FDA may refer applications for novel biologic products or biologic products that present difficult questions of safety or efficacy to an advisory
committee, typically a panel that includes clinicians and other experts, for review, evaluation, and 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.
During  the  product  approval  process,  the  FDA  also  will  determine  whether  a  REMS  is  necessary  to  assure  the  safe  use  of  the  product  candidate. A  REMS  could  include
medication guides, physician communication plans and elements to assure safe use, such as restricted distribution methods, patient registries, and other risk minimization tools.
If the FDA concludes a REMS is needed, the sponsor of the BLA must submit a proposed REMS; the FDA will not approve the BLA without a REMS, if required.

Before  approving  a  BLA,  the  FDA  will  inspect  the  facilities  at  which  the  product  candidate  is  manufactured.  The  FDA  will  not  approve  the  product  candidate  unless  it
determines that the manufacturing processes and facilities comply with cGMP requirements and are adequate to assure consistent production of the product candidate within
required  specifications. Additionally,  before  approving  a  BLA,  the  FDA  typically  will  inspect  one  or  more  clinical  sites  to  assure  that  the  clinical  trials  were  conducted  in
compliance with IND trial requirements and GCP requirements.

On  the  basis  of  the  BLA  and  accompanying  information,  including  the  results  of  the  inspection  of  the  manufacturing  facilities,  the  FDA  may  issue  an  approval  letter  or  a
complete response letter. An approval letter authorizes commercial marketing of the biologic product with specific prescribing information for specific indications. A complete
response  letter  (“CRL”)  generally  outlines  the  deficiencies  in  the  submission  and  may  require  substantial  additional  testing  or  information  for  the  FDA  to  reconsider  the
application. 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. If those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the BLA, the FDA will issue an approval letter.

If a product candidate receives regulatory approval, the approval may be significantly limited to specific diseases, patient populations, and dosages or the indications for use
may otherwise be limited. Further, the FDA may require that certain contraindications, warnings, or precautions be included in the product labeling. The FDA also may not
approve  label  statements  that  are  necessary  for  successful  commercialization  and  marketing.  The  FDA  may  impose  restrictions  and  conditions  on  product  distribution,
prescribing or dispensing in the form of a REMS, or otherwise limit the scope of any approval. In addition, the FDA may require post-marketing clinical trials, sometimes
referred to as Phase IV clinical trials, designed to further assess a biologic product’s safety and effectiveness, and testing and surveillance programs to monitor the safety of
approved products that have been commercialized.

The FDA has agreed to specified performance goals in the review of BLAs under the PDUFA. One such goal is to review 90% of standard BLAs in 10 months after the FDA
accepts the BLA for filing, and 90% of priority BLAs in six months, whereupon a review decision is to be made. The FDA does not always meet its PDUFA goal dates for
standard and priority BLAs and its review goals are subject to change from time to time. The review process and the PDUFA goal date may also be extended if new information
is submitted to the application.

Orphan drug designation

Under the Orphan Drug Act, the FDA may designate a biologic product as an “orphan drug” if it is intended to treat a rare disease or condition (generally meaning that it affects
fewer than 200,000 individuals in the United States, or more in cases in which there is no reasonable expectation that the cost of developing and making a biologic product
available in the United States for treatment of the disease or condition will be recovered from sales of the product). Additionally, sponsors must present a plausible hypothesis
for  clinical  superiority  to  obtain  orphan  drug  designation  if  there  is  a  product  already  approved  by  the  FDA  that  is  considered  by  the  FDA  to  be  the  same  as  the  already
approved product and is intended for the same indication. This hypothesis must be demonstrated to obtain orphan exclusivity. Orphan product designation must be requested
before submitting a BLA. After the FDA grants orphan product designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA.
If granted, prior to product approval, orphan drug designation 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.  Orphan  product  designation  does  not  shorten  the
duration of the regulatory review and approval process.

If  a  product  with  orphan  status  receives  the  first  FDA  approval  for  the  disease  or  condition  for  which  it  has  such  designation,  the  product  is  entitled  to  orphan  product
exclusivity, meaning that the FDA may not approve any other applications to market the same drug or biologic product for the same indication for seven years, except in limited
circumstances, such as a showing of clinical superiority to the product with orphan exclusivity or if the party holding the exclusivity fails to assure the availability of sufficient
quantities of the drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan product sameness decisions are an evolving space.
FDA has issued a final guidance document on how the agency will determine the “sameness” of gene therapy products. Pursuant to the guidance, “sameness” will depend on
the product’s transgene expression, viral vectors groups and variants, and other product features that may have a therapeutic effect. Generally, minor differences between gene
therapy products will not result in a finding that two products are different. Any FDA sameness determinations could impact our ability to receive approval for our product
candidates and to obtain or retain orphan drug exclusivity. Competitors additionally may receive approval of different products for the same indication for which the orphan
product has exclusivity or obtain approval for the same product but for a different indication for which the orphan product has exclusivity. Orphan medicinal product status in
the European Union has similar, but not identical, benefits.

Expedited development and review programs

The FDA is authorized to expedite the review of BLAs in several ways. Under the Fast Track program, the sponsor of a biologic product candidate may request the FDA to
designate the product for a specific indication as a Fast Track product concurrent with or after the filing of the IND. Biologic products are eligible for Fast Track designation if
they are intended to treat a serious or life-threatening condition and demonstrate the potential to address unmet medical needs for the condition. Fast Track designation applies
to the combination of the product candidate and the specific indication for which it is being studied. In addition to other benefits, such as the ability to have greater interactions
with the FDA, the FDA may initiate review of sections of a Fast Track BLA before the application is complete, a process known as rolling review. This “rolling review” is
available if the applicant provides and the FDA approves a schedule for the remaining information.

Any product submitted to the FDA for marketing, including under a Fast Track program, may be eligible for other types of FDA programs intended to expedite development
and review, such as breakthrough therapy designation, priority review and accelerated approval.

● Breakthrough therapy designation: To qualify for the breakthrough therapy program, product candidates must be intended to treat a serious or life-threatening disease
or  condition  and  preliminary  clinical  evidence  must  indicate  that  such  product  candidates  may  demonstrate  substantial  improvement  on  one  or  more  clinically
significant endpoints over existing therapies. The FDA will seek to ensure the sponsor of a breakthrough therapy product candidate receives the following: intensive
guidance  on  an  efficient  drug  development  program;  intensive  involvement  of  senior  managers  and  experienced  staff  on  a  proactive,  collaborative,  and  cross-
disciplinary review; and rolling review.

15

 
 
 
 
 
 
 
 
 
 
● Priority review: A product candidate is eligible for priority review if it treats a serious condition and, if approved, it would be a significant improvement in the safety
or  effectiveness  of  the  treatment,  diagnosis  or  prevention  of  a  serious  condition  compared  to  marketed  products. The  FDA  aims  to  complete  its  review  of  priority
review applications within six months as opposed to 10 months for standard review.

● Accelerated approval: Drug or biologic 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. Accelerated approval means that a product candidate may be approved on the basis of
adequate and well-controlled clinical trials establishing that the product candidate has an effect on a surrogate endpoint that is reasonably likely to predict a clinical
benefit, or on the basis of an effect on a clinical endpoint other than survival or irreversible morbidity or mortality or other clinical benefit, taking into account the
severity, rarity and prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require that a sponsor of
a drug or biologic product candidate receiving accelerated approval perform adequate and well-controlled post-marketing clinical trials. In addition, the FDA currently
requires as a condition for accelerated approval pre-approval of promotional materials. 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.

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

Finally,  with  passage  of  the  21st  Century  Cures  Act  (the  “Cures  Act”)  in  December  2016,  Congress  authorized  the  FDA  to  accelerate  review  and  approval  of  products
designated as regenerative advanced therapies. A product is eligible for this designation if it is a regenerative medicine therapy (which may include a cell or gene therapy) that
is  intended  to  treat,  modify,  reverse,  or  cure  a  serious  or  life-threatening  disease  or  condition  and  preliminary  clinical  evidence  indicates  that  the  drug  has  the  potential  to
address unmet medical needs for such disease or condition. The benefits of a regenerative advanced therapy designation include early interactions with the FDA to expedite
development  and  review,  benefits  available  to  breakthrough  therapies,  potential  eligibility  for  priority  review  and  accelerated  approval  based  on  surrogate  or  intermediate
endpoints.

Post-approval requirements

Rigorous and extensive FDA regulation of biologic products continues after approval, particularly with respect to cGMP requirements. Manufacturers are required to comply
with  applicable  requirements  in  the  cGMP  regulations,  including  quality  control  and  quality  assurance  and  maintenance  of  records  and  documentation.  Other  post-approval
requirements  applicable  to  biologic  products  include  reporting  of  cGMP  deviations  that  may  affect  the  identity,  potency,  purity  and  overall  safety  of  a  distributed  product,
record-keeping requirements, reporting of adverse events, reporting updated safety and efficacy information, and complying with electronic record and signature requirements.

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 also may be subject to official lot release. If the product is subject to
official lot release by the FDA, the manufacturer submits samples of each lot of product to the FDA, together with a release protocol, showing a summary of the history of
manufacture of the lot and the results of all tests performed on the lot. The FDA also may perform certain confirmatory tests on lots of some products before releasing the lots
for distribution. In addition, the FDA conducts laboratory research related to the regulatory standards on the safety, purity, potency, and effectiveness of biologic products.

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 subject to periodic announced and unannounced inspections by the FDA and these state agencies for compliance with
cGMP and other requirements, which impose certain procedural and documentation requirements upon the company and third-party manufacturers.

16

 
 
 
 
 
 
 
 
 
 
 
 
 
 
A sponsor also must comply with the FDA’s marketing, advertising, and promotion requirements, such as those related to direct-to-consumer advertising, the prohibition on
promoting products for uses or in patient populations that are not described in the product’s approved labeling (known as “off-label use”), industry-sponsored scientific and
educational activities and promotional activities involving the Internet. A company can make only those claims relating to a product that are approved by the FDA. 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. Biopharmaceutical 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, 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, the distribution of prescription biopharmaceutical samples is subject to the Prescription Drug Marketing Act, or PDMA, which regulates the distribution of samples
at the federal level. Both the PDMA and state laws limit the distribution of prescription biopharmaceutical product. Certain reporting related to samples is also required. Free
trial or starter prescriptions provided through pharmacies are also subject to regulations under the Medicaid Drug Rebate Program and potential liability under anti-kickback
and false claims laws.

Moreover,  the  enacted  Drug  Quality  and  Security Act,  or  DQSA,  imposed  obligations  on  sponsors  of  biopharmaceutical  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 manufacturers 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 biopharmaceutical product supply chain, such as distributors and dispensers, as well as certain sponsor licensees
and affiliates.

Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or
withdrawal of the product from the market as well as possible civil or criminal sanctions. Further, should new safety information arise, additional testing or FDA notification
may be required. In addition, changes to the manufacturing process or facility generally require prior FDA approval before being implemented and other types of changes to the
approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval, may subject an applicant or
manufacturer to administrative or judicial civil or criminal actions and adverse publicity. These actions could include refusal to approve pending applications or supplemental
applications,  withdrawal  of  an  approval,  clinical  hold,  suspension  or  termination  of  clinical  trial  by  an  IRB,  warning  or  untitled  letters,  product  recalls,  adverse  publicity,
product seizures, total or partial suspension of production or distribution, injunctions, fines or other monetary penalties, refusals of government contracts, mandated corrective
advertising  or  communications  to  healthcare  professionals  or  patients,  exclusion  from  participation  in  federal  and  state  healthcare  programs,  debarment,  restitution,
disgorgement of profits or other civil or criminal penalties.

U.S. patent term restoration and marketing exclusivity

Depending upon the timing, duration, and specifics of FDA approval of product candidates, some of a sponsor’s U.S. patents may be eligible for limited patent term extension
under the Drug Price Competition and Patent Term Restoration Act of 1984. The Hatch-Waxman Amendments permit a patent restoration term of up to five years to account for
patent term lost during the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the
product’s approval date. The patent term restoration period generally is one-half the time between the effective date of an IND and the submission date of a BLA plus the time
between the submission date of a BLA and the approval of that application. This period may also be reduced by any time that the applicant did not act with due diligence. Only
one patent applicable to an approved biologic product is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent.
The United States Patent and Trademark Office (“USPTO”), in consultation with the FDA, reviews and approves the application for any patent term extension or restoration.

17

 
 
 
 
 
 
 
 
 
Pediatric exclusivity

Pediatric exclusivity is a type of non-patent marketing exclusivity in the United States that, if granted, provides for the attachment of an additional six months of marketing
protection  to  the  term  of  any  existing  regulatory  exclusivity,  including  the  non-patent  and  orphan  exclusivity. This  six-month  exclusivity  may  be  granted  if  a  BLA  sponsor
submits pediatric data that fairly responds to a written request from the FDA for such data. The data do not need to show the product to be effective in the pediatric population
studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. If reports of requested pediatric studies are submitted to,
and accepted by, the FDA within the statutory time limits, whatever statutory or regulatory periods of exclusivity or patent protection that cover the product are extended by six
months. This is not a patent term extension, but it effectively extends the regulatory period during which the FDA cannot accept or approve a biosimilar application.

Biosimilars and exclusivity

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (“PPACA”), created an abbreviated approval pathway for
biologic products shown to be similar to, or interchangeable with, an FDA-licensed reference biologic product, referred to as biosimilars. For the FDA to approve a biosimilar
product, it must find that the biosimilar product is highly similar to the reference product notwithstanding minor differences in clinically inactive components, and that there are
no clinically meaningful differences between the reference product and proposed biosimilar product. Interchangeability requires that a product is biosimilar to the reference
product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product and, for products administered multiple times, the
biologic  and  the  reference  biologic  may  be  switched  after  one  has  been  previously  administered  without  increasing  safety  risks  or  risks  of  diminished  efficacy  relative  to
exclusive use of the reference biologic.

A reference biologic is granted 12 years of exclusivity from the time of first licensure of the reference product. An application for a biosimilar product may not be submitted to
the  FDA  until  four  years  following  approval  of  the  reference  product,  and  it  may  not  be  approved  until  12  years  thereafter.  These  exclusivity  provisions  only  apply  to
biosimilars—companies that rely on their own data and file a full BLA may be approved earlier than 12 years. Moreover, certain changes and supplements to an approved BLA,
and  subsequent  applications  filed  by  the  same  sponsor,  manufacturer,  licensor,  predecessor  in  interest,  or  other  related  entity  do  not  qualify  for  the  twelve-year  exclusivity
period.  The  PHSA  also  includes  provisions  to  protect  reference  products  that  have  patent  protection.  The  biosimilar  product  sponsor  and  reference  product  sponsor  may
exchange  certain  patent  and  product  information  for  the  purpose  of  determining  whether  there  should  be  a  legal  patent  challenge.  Based  on  the  outcome  of  negotiations
surrounding the exchanged information, the reference product sponsor may bring a patent infringement suit and injunction proceedings against the biosimilar product sponsor.
The biosimilar applicant may also be able to bring an action for declaratory judgment concerning the patent.

In an effort to increase competition in the biologic product marketplace, Congress, the executive branch, and the FDA have taken certain legislative and regulatory steps. For
example, in 2020 the FDA finalized a guidance to facilitate product importation. Moreover, the 2020 Further Consolidated Appropriations Act included provisions requiring
that  sponsors  of  approved  biologic  products,  including  those  subject  to  REMS,  provide  samples  of  the  approved  products  to  persons  developing  biosimilar  products  within
specified timeframes, in sufficient quantities, and on commercially reasonable market-based terms. Failure to do so can subject the approved product sponsor to civil actions,
penalties, and responsibility for attorney’s fees and costs of the civil action. This same bill also includes provisions with respect to shared and separate REMS programs for
reference and generic drug products.

18

 
 
 
 
 
 
 
 
Rare Pediatric Disease Voucher Program

Under the Rare Pediatric Disease Voucher Program, the FDA can award priority review vouchers to sponsors of rare pediatric disease products where the product is intended to
treat serious or life-threatening diseases that primarily affect individuals up to age 18. To qualify, the product must contain no active ingredient (including any ester or salt of the
active ingredient) that has been previously approved by the FDA. The application must also meet other qualifying criteria, including eligibility for FDA priority review. If the
necessary qualifying criteria are met, upon a sponsor’s request and product approval, the FDA may award a priority review voucher. This voucher may be transferred and may
be redeemed to receive priority review of a subsequent marketing application for a different product. Use of a priority review voucher is subject to an FDA user fee. As these
vouchers are transferable, sponsors may sell these vouchers for substantial sums of money. Vouchers may, however, be revoked by the FDA under certain circumstances and
sponsors of approved rare pediatric disease products must submit certain reports to the FDA. To take advantage of the benefits of this program, the product must be designated
by the FDA for a rare pediatric disease no later than September 30, 2024, and approved no later than September 30, 2026, unless the law is reauthorized by Congress.

Government regulation outside of the United States

In  addition  to  regulations  in  the  United  States,  sponsors  are  subject  to  a  variety  of  regulations  in  other  jurisdictions  governing,  among  other  things,  clinical  trials  and  any
commercial sales and distribution of biologic products. Because biologically-sourced raw materials are subject to unique contamination risks, their use may be restricted in
some countries.

Whether  or  not  a  sponsor  obtains  FDA  approval  for  a  product,  a  sponsor  must  obtain  the  requisite  approvals  from  regulatory  authorities  in  foreign  countries  prior  to  the
commencement  of  clinical  trials  or  marketing  of  the  product  in  those  countries.  Certain  countries  outside  of  the  United  States  have  a  similar  process  that  requires  the
submission of a clinical trial application, much like the IND, prior to the commencement of human clinical trials. Save where the Clinical Trial Regulation applies (see below)
in  relation  to  cross-border  trials,  in  the  European  Union,  for  example,  a  request  for  a  Clinical  Trial Authorization  (“CTA”)  must  be  submitted  to  the  competent  regulatory
authorities and the competent Ethics Committees in the European Union Member States in which the clinical trial takes place, much like the FDA and the IRB, respectively.
Once the CTA request is approved in accordance with the European Union and the European Union Member State’s requirements, clinical trial development may proceed.

The requirements and processes governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, the clinical
trials are conducted in accordance with GCPs and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

Failure to comply with applicable foreign regulatory requirements may result in, among other things, fines, suspension, variation or withdrawal of regulatory approvals, product
recalls, seizure of products, operating restrictions, and criminal prosecution.

European Union regulation and exclusivity

To obtain regulatory approval of an investigational biologic product under European Union regulatory systems, applicants must submit a marketing authorization application
(“MAA”).  The  grant  of  marketing  authorization  in  the  European  Union  for  products  containing  viable  human  tissues  or  cells  such  as  gene  therapy  medicinal  products  is
governed  by  Regulation  1394/2007/EC  on  advanced  therapy  medicinal  products,  read  in  combination  with  Directive  2001/83/EC  of  the  European  Parliament  and  of  the
Council, commonly known as the Community code on medicinal products and Regulation (EC) 726/2004 of the European Parliament and of the Council laying down Union
procedures for the authorization and supervision of medicinal products for human and veterinary use and establishing a European Medicines Agency. Regulation 1394/2007/EC
lays  down  specific  rules  concerning  the  authorization,  supervision  and  pharmacovigilance  of  gene  therapy  medicinal  products,  somatic  cell  therapy  medicinal  products  and
tissue  engineered  products.  Manufacturers  of  advanced  therapy  medicinal  products  must  demonstrate  the  quality,  safety  and  efficacy  of  their  products  to  the  European
Medicines  Agency  (“EMA”)  which  provides  an  opinion  regarding  the  application  for  marketing  authorization.  The  European  Commission  grants  or  refuses  marketing
authorization in light of the opinion delivered by EMA.

19

 
 
 
 
 
 
 
 
 
 
 
Innovative  medicinal  products  are  authorized  in  the  European  Union  based  on  a  full  marketing  authorization  application  (as  opposed  to  an  application  for  marketing
authorization  that  relies  on  data  in  the  marketing  authorization  dossier  for  another,  previously  approved  medicinal  product).  Applications  for  marketing  authorization  for
innovative medicinal products must contain the results of pharmaceutical tests, preclinical tests and clinical trials conducted with the medicinal product for which marketing
authorization is sought. Innovative medicinal products for which marketing authorization is granted are entitled to eight years of data exclusivity. During this period, applicants
for approval of generics or biosimilars of these innovative products cannot make an MMA relying on data contained in the marketing authorization dossier submitted for the
innovative medicinal product to support their application and such generics or biosimilars cannot be placed on the market until 10 years after the first EU marketing of the
reference product. The overall 10-year period will be extended to a maximum of 11 years if, during the first eight years of those 10 years, the marketing authorization holder
obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical
benefit in comparison with existing therapies. Even if a compound is considered to be a new chemical entity and the innovator is able to gain the period of data exclusivity,
another company, nevertheless, could also market another competing medicinal product for the same therapeutic indication if such company obtained marketing authorization
based on an MAA with a complete independent data package of pharmaceutical tests, preclinical tests and clinical trials.

Products receiving orphan designation in the European Union can receive 10 years of market exclusivity. During this 10-year period, the competent authorities of the European
Union  Member  States  and  European  Commission  may  not  accept  applications  or  grant  marketing  authorization  for  other  similar  medicinal  product  for  the  same  orphan
indication. There are, however, three exceptions to this principle. Marketing authorization may be granted to a similar medicinal product for the same orphan indication if:

● The second applicant can establish in its application that its medicinal product, although similar to the orphan medicinal product already authorized, is safer, more

effective or otherwise clinically superior;

● The holder of the marketing authorization for the original orphan medicinal product consents to a second orphan medicinal product application; or
● The holder of the marketing authorization for the original orphan medicinal product cannot supply sufficient quantities of orphan medicinal product.

An orphan product can also obtain an additional two years of market exclusivity in the European Union for the conduct of pediatric trials. The 10-year market exclusivity may
be  reduced  to  six  years  if,  at  the  end  of  the  fifth  year,  it  is  established  that  the  product  no  longer  meets  the  criteria  for  orphan  designation;  for  example,  if  the  product  is
sufficiently profitable and no longer justifies the maintenance of market exclusivity or if the manufacturer cannot produce sufficient quantities to supply the orphan population.

The criteria for designating an “orphan medicinal product” in the European Union are similar, in principle, to those in the United States. Orphan medicinal products are eligible
for  financial  incentives  such  as  reduction  of  fees  or  fee  waivers.  The  application  for  orphan  medicinal  product  designation  must  be  submitted  before  the  application  for
marketing authorization. Orphan medicinal product designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

In April  2014,  the  EU  adopted  a  new  Clinical  Trials  Regulation  (EU)  No  536/2014  (the  “Clinical  Trials  Regulation”),  which  replaced  the  current  Clinical  Trials  Directive
2001/20/EC (the “Clinical Trials Directive”) on January 31, 2022. The Clinical Trial Regulation has overhauled the previous system of approvals for clinical trials in the EU
whereby all clinical trial approvals were granted purely on a national basis. Specifically, the legislation, which is directly applicable in all member states, aims at simplifying
and streamlining the approval of clinical trials in the EU, whereby there is a streamlined application procedure via a single-entry point and strictly defined deadlines for the
assessment of clinical trial applications. However, the Clinical Trial Regulation does increase public disclosure requirements in relation to clinical trial information.

In the European Union there are also broadly equivalent regimes for the other issues addressed in relation to US regulation including cGMP requirements, accelerated access
(generally through so-called Conditional Marketing Authorizations), pediatric requirements and incentives and patent term restoration (supplementary protection certificates).

Other Healthcare Laws and Regulations

Healthcare providers, physicians and third-party payors play a primary role in the recommendation and use of pharmaceutical products that are granted marketing approval.
Arrangements  with  third-party  payors,  existing  or  potential  customers  and  referral  sources  are  subject  to  broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and
regulations, and these laws and regulations may constrain the business or financial arrangements and relationships through which manufacturers market, sell and distribute the
products for which they obtain marketing approval. Such restrictions under applicable federal and state healthcare laws and regulations include the following:

● the federal Anti-Kickback Statute, which prohibits, among other things, persons, and entities from knowingly and willfully soliciting, receiving, offering or paying
remuneration, directly or indirectly, in cash or kind, in exchange for, or to induce, either the referral of an individual for, or the purchase, order or recommendation of,
any  good  or  service  for  which  payment  may  be  made  under  federal  healthcare  programs  such  as  the  Medicare  and  Medicaid  programs.  This  statute  has  been
interpreted  to  apply  to  arrangements  between  pharmaceutical  manufacturers,  on  the  one  hand,  and  prescribers,  purchasers,  and  formulary  managers  on  the  other.
Although a number of statutory exemptions and regulatory safe harbors exist to protect certain common activities from falling under the Anti-Kickback Statute, these
are narrow, and practices may not fall under the applicable safe harbors and exemptions. For example, the United States Department of Health and Human Services
recently promulgated a regulation that is effective in two phases. First, the regulation excludes from the definition of “remuneration” limited categories of (a) PBM
rebates or other reductions in price to a plan sponsor under Medicare Part D or a Medicaid Managed Care Organization plan reflected in point-of sale reductions in
price and (b) PBM service fees. Second, effective January 1, 2023, the regulation expressly provides that rebates to plan sponsors under Medicare Part D either directly
to the plan sponsor under Medicare Part D, or indirectly through a pharmacy benefit manager will not be protected under the anti-kickback discount safe harbor. The
PPACA amended the intent requirement of the federal Anti-Kickback Statute. A person or entity no longer needs to have actual knowledge of this statute or specific
intent to violate it in order to commit a violation;

● the federal false claims and civil monetary penalties laws, including the civil False Claims Act (the “FCA”), which prohibit, among other things, individuals, or entities
from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid or other third-party payors that are false or fraudulent, or making
a false statement to avoid, decrease, or conceal an obligation to pay money to the federal government. Certain marketing practices, including off-label promotion, also
may implicate the FCA. FCA claims may be pursued by whistleblowers through qui tam actions, even if the government declines to intervene and civil liability may be
predicated on reckless disregard for the truth. The PPACA also codified case law that a claim including items or services resulting from a violation of the federal Anti-
Kickback  Statute  constitutes  a  false  or  fraudulent  claim  for  purposes  of  the  FCA.  Separately,  the  criminal  federal  False  Claims  Act  imposes  criminal  fines  or
imprisonment against individuals or entities who make or present a claim to the government knowing such claim to be false, fictitious, or fraudulent;

● the federal Physician Payments Sunshine Act, which requires certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available
under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services
(“CMS”), information related to payments and other transfers of value made to or at the request of covered recipients, such as, but not limited to, physicians, physician
assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified  registered  nurse  anesthetists  and  teaching  hospitals,  as  well  as  ownership  and  investment  interests
held by physicians and their immediate family. Payments made to physicians and certain research institutions for clinical trials are included within the ambit of this
law. Reported information is made publicly available in searchable formats by CMS;

● additional federal false statements and fraud and abuse statutes prohibit 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.  PPACA  amended  the  intent  requirement  of  certain  of  these  criminal  statutes  under  the  Health
Insurance Portability and Accountability Act of 1996 (“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; and

21

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● state and foreign law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by
any  third-party  payor,  including  commercial  insurers;  state  laws  that  require  pharmaceutical  companies  to  comply  with  the  pharmaceutical  industry’s  voluntary
compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare
providers  and  other  potential  referral  sources;  state  laws  that  require  drug  manufacturers  to  report  information  related  to  payments  and  other  transfers  of  value  to
physicians and other healthcare providers or marketing expenditures; and European Union and state laws governing the privacy and security of health information in
certain circumstances, many of which differ from each other in significant ways, may be stricter than those applicable in the US and may not have the same effect, thus
complicating compliance efforts.

Violation  of  the  laws  described  above  or  any  other  governmental  laws  and  regulations  may  result  in  penalties,  including  civil  and  criminal  penalties,  damages,  fines,  the
curtailment or restructuring of operations, the exclusion from participation in federal and state healthcare programs, debarment from government contracting or refusal of orders
under existing contracts, corporate integrity agreements or consent decrees, disgorgement, contractual damages, reputational harm, diminished profits and future earnings, and
imprisonment. Furthermore, efforts to ensure that business activities and business arrangements comply with applicable healthcare laws and regulations can be costly.

Data Privacy and Security

● HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH Act, and similar state laws impose obligations
on certain entities with respect to safeguarding the privacy, security and transmission of protected health information. HIPAA’s security and certain privacy standards
are directly applicable to persons or organizations of covered entities, other than members of the covered entity’s workforce, that create, receive, maintain or transmit
protected  health  information  on  behalf  of  a  covered  entity  for  a  function  or  activity  regulated  by  HIPAA.  The  HITECH Act  strengthened  the  civil  and  criminal
penalties  that  may  be  imposed  against  covered  entities,  business  associates  and  individuals,  and  gave  state  attorneys  general  new  authority  to  file  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, such as the California Consumer Privacy Act, may regulate the privacy and security of information that we maintain, many of
which may differ from each other in significant ways and may not be preempted by HIPAA; and

● the General European Data Protection Regulation (“GDPR”), which became applicable May 25, 2018, harmonizes data privacy laws across Europe. The GDPR sets
forth  rules  relating  to  the  protection  with  regard  to  the  processing  and  transfer  of  personal  data  as  well  as  an  individual’s  right  to  the  protection  of  personal  data,
including  medical  information  and  clinical  trial  related  data.  In  addition,  there  are  rules  relating  to  the  export  of  personal  data  outside  the  European  Union  and  in
particular there are certain challenges in relation to export to the United States.

Coverage and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any products for which we may obtain regulatory approval. In the United States, sales of any
product candidates for which regulatory approval for commercial sale is obtained will depend in part on the availability of coverage and adequate reimbursement from third-
party payors. Third-party payors include government authorities and health programs in the United States such as Medicare and Medicaid, managed care providers, private
health  insurers  and  other  organizations. These  third-party  payors  are  increasingly  reducing  reimbursements  for  medical  products  and  services. The  process  for  determining
whether a payor will provide coverage for a drug product may be separate from the process for setting the reimbursement rate that the payor will pay for the drug product.
Third-party payors may limit coverage to specific drug products on an approved list, or formulary, which might not include all FDA-approved drugs for a particular indication.
Additionally, the containment of healthcare costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort. The U.S.
government,  state  legislatures  and  foreign  governments  have  shown  significant  interest  in  implementing  cost-containment  programs,  including  price  controls,  required
disclosures  of  pricing  and  sensitive  cost  data,  requirement  for  payment  of  manufacturer  rebates  and  negotiation  of  supplemental  rebates,  restrictions  on  reimbursement  and
requirements  for  substitution  of  generic  products.  Coverage  policies  and  third-party  reimbursement  rates  may  change  at  any  time.  Even  if  favorable  coverage  and
reimbursement  status  is  attained  for  one  or  more  products  for  which  we  receive  regulatory  approval,  less  favorable  coverage  policies  and  reimbursement  rates  may  be
implemented in the future.

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
In the EU, pricing and reimbursement schemes vary widely from country to country. Some countries provide that products may be marketed only after a reimbursement price
has been agreed. Some countries may require the completion of additional studies as part of health technology assessment that compare the cost-effectiveness of a particular
product candidate to currently available therapies. EU member states may approve a specific price for a product, or it may instead adopt a system of direct or indirect controls
on  the  profitability  of  the  company  placing  the  product  on  the  market.  Other  member  states  allow  companies  to  fix  their  own  prices  for  products  but  monitor  and  control
company profits. The downward pressure on health care costs has become intense. As a result, increasingly high barriers are being erected to the entry of new products. In
addition,  in  some  countries,  cross-border  imports  from  low-priced  markets  exert  competitive  pressure  that  may  reduce  pricing  within  a  country. Any  country  that  has  price
controls or reimbursement limitations may not allow favorable reimbursement and pricing arrangements.

Health Reform

The United States and some foreign jurisdictions are considering or have enacted a number of reform proposals to change the healthcare system. There is significant interest in
promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality, or expanding access. In the United States, the pharmaceutical
industry has been a particular focus of these efforts. For example, healthcare reform measures under the Affordable Care Act included increased Medicaid rebates, expanded the
340B drug discount program, and changes requiring manufacturer discounts currently set at 70 percent on Part D utilization in the Part D coverage gap or “donut hole” and
multiple provisions that could affect the profitability of our drug products. There is continuing development of value-based pricing and reimbursement models. Moreover, on
November 27, 2020, CMS issued an interim final rule implementing a Most Favored Nation payment model under which reimbursement for certain Medicare Part B drugs and
biologicals  will  be  based  on  a  price  that  reflects  the  lowest  per  capita  Gross  Domestic  Product-adjusted  (GDP-adjusted)  price  of  any  non-U.S.  member  country  of  the
Organization  for  Economic  Co-operation  and  Development  (OECD)  with  a  GDP  per  capita  that  is  at  least  sixty  percent  of  the  U.S.  GDP  per  capita.  Current  and  future
healthcare  reform  measures  may  significantly  affect  our  sale  of  any  products,  and  we  continue  to  face  major  uncertainty  due  to  the  status  of  major  legislative  initiatives
surrounding healthcare reform.

Additional Regulation

In  addition  to  the  foregoing,  state  and  federal  laws  regarding  environmental  protection  and  hazardous  substances,  including  the  Occupational  Safety  and  Health  Act,  the
Resource Conservation and Recovery Act and the Toxic Substances Control Act, affect our business. These and other laws govern the use, handling and disposal of various
biologic and chemical substances used in, and wastes generated by, operations. If our operations result in contamination of the environment or expose individuals to hazardous
substances, we could be liable for damages and governmental fines. Equivalent laws have been adopted in other countries that impose similar obligations.

U.S. Foreign Corrupt Practices Act

The  U.S.  Foreign  Corrupt  Practices Act  (“FCPA”),  prohibits  U.S.  corporations  and  individuals  from  engaging  in  certain  activities  to  obtain  or  retain  business  abroad  or  to
influence a person working in an official capacity. It is illegal to pay, offer to pay or authorize the payment of anything of value to any foreign government official, government
staff member, political party, or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in an official capacity. The scope of the
FCPA  includes  interactions  with  certain  healthcare  professionals  in  many  countries.  Equivalent  laws  have  been  adopted  in  other  foreign  countries  that  impose  similar
obligations.

Competition

Companies  that  are  currently  engaged  in  gene  therapy  or  companies  not  yet  focused  on  developing  cell  and  gene  therapies  could  at  any  time  decide  to  develop  therapies
relevant to our business. Many of our competitors, either alone or with their strategic partners, may have substantially greater financial, technical, and human resources than we
do and may have significantly greater experience in the discovery and development of product candidates, obtaining FDA and other regulatory approvals of product candidates
and  commercializing  those  product  candidates. Accordingly,  our  competitors  may  be  more  successful  than  us  in  obtaining  approval  for  product  candidates  and  achieving
widespread  market  acceptance.  Our  competitors’  product  candidates  may  be  more  effective,  or  more  effectively  marketed  and  sold,  than  any  product  candidate  we  may
commercialize  and  may  render  our  treatments  obsolete  or  non-competitive  before  we  can  recover  the  expenses  of  developing  and  commercializing  any  of  our  product
candidates.

23

 
 
 
 
 
 
 
 
 
 
 
Mergers and acquisitions in the biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors.
These  competitors  also  may  compete  with  us  in  recruiting  and  retaining  qualified  scientific  and  management  personnel  and  establishing  clinical  trial  sites  and  subject
registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Smaller or early-stage companies may also prove to be
significant competitors, particularly through collaborative arrangements with large and established companies.

We  anticipate  facing  intense  and  increasing  competition  as  new  product  candidates  enter  the  market  and  advanced  technologies  become  available.  We  expect  any  product
candidates  that  we  develop  and  commercialize  to  compete  on  the  basis  of,  among  other  things,  efficacy,  safety,  convenience  of  administration  and  delivery,  price,  and  the
availability of reimbursement from government and other third-party payors.

Our commercial opportunity 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. Our competitors also may obtain FDA or other regulatory approval for their product
candidates  more  rapidly  than  we  may  obtain  approval  for  ours,  which  could  result  in  our  competitors  establishing  a  strong  market  position  before  we  are  able  to  enter  the
market.

ITEM 1A. RISK FACTORS

Our  business,  financial  condition,  financial  results,  and  future  growth  prospects  are  subject  to  a  number  of  risks  and  uncertainties,  including  those  set  forth  below.  The
occurrence of any of the following risks could have a material adverse effect on our business, financial condition, financial results, and future growth prospects. Additional
risks  and  uncertainties  that  are  not  currently  known  to  us  or  that  we  do  not  currently  believe  to  be  material  may  also  negatively  affect  our  business,  financial  condition,
financial results, and future growth prospects.

Our business is subject to numerous risks and uncertainties, including those described in Item 1A “Risk Factors.” These risks include, but are not limited to the following:

RISK FACTOR SUMMARY

● Our  cell  and  gene  therapy  product  candidates  are  based  on  proprietary  methodologies,  which  makes  it  difficult  to  predict  the  time  and  cost  of  product  candidate
development and regulatory approval. Additionally, regulatory requirements governing cell and gene therapy products have evolved and may continue to change in the
future.

● If we do not obtain the necessary U.S. or worldwide regulatory approvals to commercialize EB-101, we will not be able to sell EB-101.
● Even if we receive regulatory approval for EB-101, our lead drug candidate, we may not be able to successfully commercialize the product and the revenue that we

generate from its sales, if any, may be limited.

● We may encounter substantial delays in our clinical studies or we may fail to demonstrate safety and efficacy to the satisfaction of applicable regulatory authorities.

Additionally, we may find it difficult to enroll patients in our clinical studies, which could delay or prevent clinical studies of our product candidates.

● We have received and may apply for additional designations such as breakthrough therapy designation, RMAT designation, fast track designation, and rare pediatric
disease designation from the FDA intended to facilitate or encourage product candidate development. We may not receive any such designations or be able to maintain
them. Moreover, any such designations may not lead to faster development or regulatory review or approval and it does not increase the likelihood that our product
candidates will receive marketing approval.

● While certain of our product candidates have received orphan drug designation from the FDA, there is no guarantee that we will be able to maintain this designation,

receive this designation for any of our other product candidates, or receive or maintain any corresponding benefits, including periods of exclusivity.

● Even if we obtain regulatory approval for a product candidate, our products will remain subject to regulatory scrutiny.
● The COVID-19 pandemic and efforts to reduce its spread have affected our operations and significantly impacted worldwide economic conditions, and could continue

to have a material effect on our operations, business, and financial condition.

● We  could  experience  production  problems  in  our  manufacturing  facilities  that  result  in  delays  in  our  development  or  commercialization  programs.  We  might  also
experience  delays  in  manufacturing  if  any  of  our  vendors,  contract  laboratories  or  suppliers  are  found  to  be  out  of  compliance  with  current  Good  Manufacturing
Practice.

● If we fail to comply with applicable regulations, the relevant regulatory authority may require remedial measures that may be costly or time-consuming to implement

and that may include the suspension of a clinical trial or commercial sales or the closure of a manufacturing facility.

● The widespread outbreak of an illness, communicable disease, or any other public health crisis could adversely affect our business, results of operations and financial

condition.

● We expect to rely on third parties, and these third parties may not perform satisfactorily. Additionally, our reliance on third parties requires us to share our trade secrets,

which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated.

● Our drug candidates are subject to the risks of failure inherent in the development of pharmaceutical products based on new technologies, and our failure to develop

safe and commercially viable drugs would severely limit our ability to become profitable or to achieve significant revenues.

25

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● We may be unable to successfully develop, market, or commercialize our products or our product candidates without establishing new relationships and maintaining
current relationships and our ability to successfully commercialize, and market our product candidates could be limited if a number of these existing relationships are
terminated.

● We may incur substantial product liability expenses due to the use or misuse of our products for which we may be unable to obtain insurance coverage.
● Our ability to successfully develop and commercialize our drug candidates will substantially depend upon the availability of reimbursement funds for the costs of the

resulting drugs and related treatments.

● The market may not accept any pharmaceutical products that we develop, and adverse public perception of gene therapy products may negatively affect demand for, or

regulatory approval of, our product candidates.

● We may be subject to federal, state, and foreign healthcare laws and regulations, including fraud and abuse laws, false claims laws, health information privacy and

security laws and data privacy laws. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.

● Our business could suffer if we lose the services of, or fail to attract, key personnel.
● Trends toward managed health care and downward price pressures on medical products and services may limit our ability to profitably sell any drugs that we may

develop.

● Our rights to develop and commercialize our product candidates are subject to, in part, the terms and conditions of licenses granted to us by others.
● If we are unable to obtain and maintain patent protection for our product candidates and technology, or if the scope of the patent protection obtained is not sufficiently

broad, our competitors could develop and commercialize products and technology similar or identical to ours.
● Our intellectual property licenses with third parties may be subject to disagreements over contract interpretation.
● We may not be successful in obtaining necessary rights to our product candidates through acquisitions and in-licenses.
● We may not be able to protect our intellectual property rights around the world.
● Issued patents covering our product candidates could be found invalid or unenforceable if challenged in court. We may not be able to protect our trade secrets in court,

and intellectual property litigation could cause us to spend substantial resources.

● Third-parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could harm

our business.

● We may be subject to claims asserting that our employees, consultants or advisors have wrongfully used or disclosed alleged trade secrets of their current or former

employers or claims asserting ownership of what we regard as our own intellectual property.

● If we do not obtain patent term extension and data exclusivity for our product candidates, our business may be harmed.
● We have experienced a history of losses; we expect to incur future losses and we may be unable to obtain necessary additional capital to fund operations in the future.

We do not have significant operating revenue and may never achieve profitability.

● Failure to achieve and maintain effective internal controls could have a material adverse effect on our business.
● We expect to continue to need to raise additional capital to operate our business, and our failure to obtain funding when needed or on terms that are favorable to us

may force us to delay, reduce or eliminate our development programs or aspects thereof.

● The market price of our common stock may be volatile and adversely affected by several factors.
● Raising  additional  funds  by  issuing  securities  or  through  licensing  or  lending  arrangements  or  through  our  at-the-market  sale  agreement  may  cause  dilution  to  our

existing stockholders, restrict our operations or require us to relinquish proprietary rights.

● Our quarterly operating results may fluctuate significantly.
● Provisions of our charter documents could discourage an acquisition of our company.

Risks related to the discovery and development of our product candidates

Our  cell  and  gene  therapy  product  candidates  are  based  on  proprietary  methodologies,  which  makes  it  difficult  to  predict  the  time  and  cost  of  product  candidate
development and subsequently obtaining regulatory approval. Only a few gene therapy products have been approved in the U.S. and the EU.

We  have  concentrated  our  therapeutic  product  research  and  development  efforts  on  our  cell  and  gene  therapy  platform,  and  our  future  success  depends  on  the  successful
development of this therapeutic approach. There can be no assurance that any development problems we experience in the future related to our cell and gene therapy platform
will  not  cause  significant  delays  or  unanticipated  costs,  or  that  such  development  problems  can  be  solved.  We  may  also  experience  delays  in  developing  a  sustainable,
reproducible and commercial-scale manufacturing process or transferring that process to commercial partners, which may prevent us from completing our clinical studies or
commercializing our products on a timely or profitable basis, if at all.

In addition, the clinical study requirements of the FDA, the EMA, and other regulatory agencies and the criteria these regulators use to determine the safety and efficacy of a
product candidate vary substantially according to the type, complexity, novelty and intended use and market of the potential products. The regulatory approval process for novel
product candidates such as ours can be more expensive and take longer than for other, better known or more extensively studied pharmaceutical or other product candidates.
Given that only a few gene therapy products have been approved in the Western world, it is not possible to predict how long it will take or how much it will cost to obtain
regulatory approvals for our product candidates in the United States, the EU or other jurisdictions. Approvals by the EMA and the European Commission may not be indicative
of what the FDA may require for approval.

Regulatory  requirements  governing  cell  and  gene  therapy  products  have  evolved  and  may  continue  to  change  in  the  future.  For  example,  the  FDA  has  established  the
Office Tissues and Advanced Therapies within 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.

Regulatory requirements in the United States and in other jurisdictions governing gene therapy products have changed frequently and will continue to change in the future as
scientific knowledge is acquired. The FDA and EMA have each expressed interest in further regulating gene therapy. For example, the FDA has established the Office Tissues
and Advanced Therapies within 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. Over the last few years, FDA, through CBER, has provided significant guidance regarding the development of gene therapies. Additionally, the
EMA  advocates  a  risk-based  approach  to  the  development  of  a  gene  therapy  product. Agencies  at  both  the  federal  and  state  level  in  the  United  States,  as  well  as  the  U.S.
congressional committees and other governments or governing agencies, have also expressed interest in further regulating the biotechnology industry. Such action may delay or
prevent  commercialization  of  some,  or  all,  of  our  product  candidates.  These  regulatory  review  agencies,  committees  and  advisory  groups  and  the  new  requirements  and
guidelines they promulgate may lengthen the regulatory review process, require us to perform additional or larger studies, increase our development costs, lead to changes in
regulatory positions and interpretations, delay or prevent approval and commercialization of these treatment candidates or lead to significant post-approval studies, limitations,
or restrictions. As we advance our product candidates, we will be required to consult with these regulatory and advisory groups and comply with applicable requirements and
guidelines. If we fail to do so, we may be required to delay or discontinue development of our 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.

We  may  encounter  substantial  delays  in  our  clinical  studies,  such  as  clinical  holds,  or  we  may  fail  to  demonstrate  safety  and  efficacy  to  the  satisfaction  of  applicable
regulatory authorities.

Before obtaining marketing approval from regulatory authorities for the sale of our product candidates, we must conduct extensive clinical studies to demonstrate the safety,
purity and potency, and efficacy, of the product candidates in humans. Clinical testing is expensive, time-consuming, and uncertain as to outcome. This is especially true for
rare and/or complicated diseases. We cannot guarantee that any clinical studies will be conducted as planned or completed on schedule, if at all. A failure of one or more clinical
studies can occur at any stage of testing.

27

 
 
 
 
 
 
 
 
 
 
The results of preclinical studies, preliminary study results, and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials or
the  ultimately  completed  trial.  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. Preclinical and early clinical studies may also reveal unfavorable product candidate characteristics, including safety concerns. We
may also 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 or IRBs 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 or IRBs 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

CROs;

● regulators  may  require  us  to  perform  additional  or  unanticipated  clinical  trials  to  obtain  approval  or  we  may  be  subject  to  additional  post-marketing  testing,

surveillance, or REMS requirements to maintain regulatory approval;

● flaws in a clinical trial may not become apparent until the trial is well advanced;
● clinical trials of our product candidates may produce negative or inconclusive results, or our studies may fail to reach the necessary level of statistical significance, and

we may decide, or regulators may require us, to conduct additional clinical trials or abandon product development programs;

● clinical trials of our product candidates may require us to provide follow-up patient visits for safety for a minimum of five years even if we were to terminate and/or

abandon a product development program;

● our third-party contractors may fail to comply with regulatory requirements or the clinical trial protocol, or fail to 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;

● we, the regulators, or IRBs 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 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 and regulatory review policies or changes in or the enactment of additional statutes or regulations;
● the cost of clinical trials of and marketing applications for our product candidates may be greater than we anticipate;
● the supply or quality of our product candidates or other materials necessary to conduct clinical trials may be insufficient or inadequate;
● we  may  decide,  or  regulators  may  require  us,  to  conduct  or  gather,  as  applicable,  additional  clinical  trials,  analyses,  reports,  data,  or  preclinical  trials,  or  we  may

abandon product development programs;

● we may fail to reach an agreement with regulators or IRBs regarding the scope, design, or implementation of our clinical trials. For instance, the FDA or comparable

foreign regulatory authorities may require changes to our study design that make further study impractical or not financially prudent;

● we may have delays in adding new investigators or clinical trial sites, or we may experience a withdrawal of clinical trial sites;
● there may be regulatory questions or disagreements regarding interpretations of data and results, or new information may emerge regarding our product candidates;
● we  may  make  changes  to  our  product  candidates  or  their  manufacturing  process  that  necessitate  additional  studies  or  that  result  in  our  product  candidates  not

performing as expected;

● 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 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 submission in foreign jurisdictions or to obtain regulatory approval in the United States or
elsewhere;

● if one of our product candidates does not receive marketing approval in one country, it may impact our ability to receive marketing approval in other countries;
● the FDA or comparable 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.

Delays in launching clinical trials resulting from FDA or other regulatory actions, such as a clinical hold letter, would delay the commercialization of our product candidates
and our ability to generate revenue, which would have an adverse effect on our business. For example, in September 2019, we received a clinical hold letter in connection with
our Phase 3 clinical trial for EB-101 stating that the FDA would not provide approval for us to begin our planned Phase 3 clinical trial for EB-101 until we submitted additional
data points on transport stability of EB-101 to clinical sites. Although the FDA removed the clinical hold in December 2019 and provided clearance for us to proceed with our
planned Phase 3 clinical trial, we may encounter similar delays in our clinical studies in the future.

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 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 any of the foregoing were to occur, our business, financial condition, results of operations, and prospects will be materially harmed.

We may find it difficult to enroll patients in our clinical studies, which could delay or prevent clinical studies of our product candidates.

Identifying and qualifying patients to participate in clinical studies of our product candidates is critical to our success. The timing of our clinical studies depends on the speed at
which we can recruit eligible patients to participate in testing our product candidates. We have experienced delays in some of our clinical studies due to the ultra-rare nature of
the diseases we aim to treat, and we may experience similar delays in the future. If patients are unwilling to participate in our cell and gene therapy studies because of negative
publicity from adverse events in the biotechnology or gene therapy industries or for other reasons, including competitive clinical studies 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 technology or termination of the clinical studies altogether.

We may not be able to identify, recruit or enroll a sufficient number of patients, or those with required or desired characteristics to achieve diversity in a study, to complete our
clinical studies in a timely manner. Patient enrollment is affected by factors including:

● severity of the disease under investigation;
● design of the study protocol;
● size and nature of the patient population;
● eligibility criteria for and design of the study in question;
● perceived risks and benefits of the product candidate under study, including as a result of adverse effects observed in similar or competing therapies;
● proximity and availability of clinical study sites for prospective patients;
● availability of competing therapies and clinical studies;
● efforts to facilitate timely enrollment in clinical studies;
● ability to compensate patients for their time and effort;
● risk that enrolled patients will drop out before completion or not return for post-treatment follow-up;
● inability to obtain or maintain patient informed consents;

29

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● effectiveness of publicity created by clinical trial sites regarding the trial;
● patient referral practices of physicians; and
● ability to monitor patients adequately during and after treatment.

We also plan to seek initial marketing approval in the European Union in addition to the U.S. Our ability to successfully initiate, enroll and complete a clinical study in any
foreign country is subject to additional risks unique to conducting business in foreign countries, such as different standards for the conduct of clinical studies; different laws,
medical standards, and regulatory requirements; and the ability to establish or manage relationships with treatment centers, contract research organizations and physicians.

If we have difficulty enrolling a sufficient number of patients to conduct our clinical studies as planned our development costs may increase, the time for completion of clinical
trials may increase, we may need to delay, limit or terminate ongoing or planned clinical studies, any of which would have an adverse effect on our business.

Our products or product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval or commercialization.

Undesirable side effects caused by our products or product candidates, including adverse events associated with our product candidates, could interrupt, delay, or halt clinical
trials and could result in the denial of regulatory approval or more limited approvals by the FDA, EMA or other regulatory 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, or 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 in turn prevent us from commercializing our products or product candidates and generating revenues from their sale.

In addition, if we or others identify undesirable side effects caused by our product candidates after receipt of marketing approval, the regulatory authorities may require the
addition  of  restrictive  labeling  statements.  Regulatory  authorities  may  withdraw  their  approval  of  the  product.  We  also  may  be  required  to  change  the  way  the  product  is
administered or conduct additional clinical trials. Any of these events could prevent us from achieving or maintaining market acceptance of the affected products or product
candidate or could substantially increase the costs and expenses of commercializing the products or product candidate, which in turn could delay or prevent us from generating
significant revenues from its sale or adversely affect our reputation.

Even if we complete the necessary preclinical and clinical studies, we cannot predict when or if we will obtain regulatory approval to commercialize a product candidate or
the approval may be for a narrower indication than we expect.

We cannot commercialize a product until the appropriate regulatory authorities have reviewed and approved the product candidate. Even if our product candidates demonstrate
safety and efficacy in clinical studies, the regulatory agencies may not complete their review processes in a timely manner, or we may not be able to obtain regulatory approval.
Additional delays may result if an FDA Advisory Committee or other regulatory advisory group or authority recommends non-approval or restrictions on approval. In addition,
we  may  experience  delays  or  rejections  based  on  additional  government  regulation  from  future  legislation  or  administrative  action,  or  changes  in  regulatory  agency  policy
during  the  period  of  product  development,  clinical  studies,  and  the  review  process.  Regulatory  agencies  also  may  approve  a  treatment  candidate  for  fewer  or  more  limited
indications, populations, or uses than requested or may grant approval subject to the performance of post-marketing studies, surveillance, or other requirements. In addition,
regulatory  agencies  may  not  approve  the  labeling  claims  that  are  necessary  or  desirable  for  the  successful  commercialization  of  our  treatment  candidates,  or  may  require
significant safety warnings, including black box warnings, contraindications, and precautions. For example, the development of our product candidates for pediatric use is an
important part of our current business strategy, and if we are unable to obtain regulatory approval for the desired age ranges, our business may suffer.

We have received and may apply for additional designations intended to facilitate or encourage product candidate development. We may not receive any such designations
or be able to maintain them. Moreover, any such designations may not lead to faster development or regulatory review or approval and it does not increase the likelihood
that our product candidates will receive marketing approval.

Our product candidates have received regulatory designations including breakthrough therapy designation, RMAT designation, fast track designation, and rare pediatric disease
designation from the FDA. In the future and as appropriate, we may seek additional product designations. Receipt of such a designation is within the discretion of the FDA.
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. Finally, specifically with respect to our rare pediatric disease designations, if we are not able to obtain FDA approval of our
designated product candidates before the statute sunsets, we would not be eligible to receive priority review vouchers.

Certain of our product candidates have received orphan drug designation from the FDA, there is no guarantee that we will be able to maintain this designation, receive
this designation for any of our other product candidates, or receive or maintain any corresponding benefits, including periods of exclusivity.

While orphan drug designation provides certain advantages, it neither shortens the development time or regulatory review time of a product candidate nor gives the product
candidate any advantage in the regulatory review or approval process. Generally, if a product candidate with orphan drug designation subsequently receives marketing approval
before another product considered by the FDA or comparable foreign regulatory authorities to be the same, for the same orphan indication, the product is entitled to a period of
marketing exclusivity, which precludes the FDA or comparable foreign regulatory authorities from approving another marketing application for the same drug or biologic for
the same indication for seven years. We may not be able to obtain any future orphan drug designations that we apply for, orphan drug designations 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 orphan drug designations that we receive. For instance,
orphan drug designation may be revoked if the FDA finds that the request for designation contained an untrue statement of 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, 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 approval is broader than the designation. Orphan exclusivity may also be lost for the same reasons that the designation 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 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 comparable foreign regulatory authorities can also subsequently approve a product containing the same principal molecular features for the same condition if the FDA
concludes that the later product is clinically superior. The FDA may further grant orphan drug designation to multiple sponsors for the same compound or active molecule and
for  the  same  indication.  If  another  sponsor  receives  FDA  or  comparable  foreign  regulatory  authority  approval  for  such  product  before  we  do,  we  would  be  prevented  from
launching our product for the orphan indication for a period of at least seven years unless we can demonstrate clinical superiority. FDA’s thinking around sameness with respect
to  gene  therapies,  and  thus  the  circumstances  when  clinical  superiority  would  need  to  be  shown,  is  evolving. While  the  agency  has  issued  a  guidance  on  the  topic,  certain
decisions may need to be made on a case by case basis, given the novelty of the technology. Moreover, third-party payors may reimburse for products off-label even if not
indicated for the orphan condition.

31

 
 
 
 
 
 
 
Even if we obtain regulatory approval for a product candidate, our products will remain subject to regulatory scrutiny.

Even  if  we  obtain  regulatory  approval  in  a  jurisdiction,  regulatory  authorities  may  still  impose  significant  restrictions  on  the  indicated  uses  or  marketing  of  our  product
candidates  or  impose  ongoing  requirements  for  potentially  costly  post-approval  studies,  post-market  surveillance  or  patient  or  drug  restrictions.  Moreover,  the  FDA  and
comparable foreign regulatory authorities will continue to closely monitor the safety profile of any product even after approval, including gene therapy specific requirements
for long term follow up. Additionally, the holder of an approved BLA is obligated to monitor and report adverse events and any failure of a product to meet the specifications in
the BLA. The holder of an approved BLA must also submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product
labeling  or  manufacturing  process.  Advertising  and  promotional  materials  must  comply  with  FDA  rules  and  are  subject  to  FDA  review,  in  addition  to  other  potentially
applicable federal and state laws.

In  addition,  product  manufacturers  and  their  facilities  are  subject  to  payment  of  user  fees  and  continual  review  and  periodic  inspections  by  the  FDA  and  other  regulatory
authorities for compliance with cGMP and adherence to commitments made in the BLA. If we or a regulatory agency discovers previously unknown problems with a product,
such as adverse events of unanticipated severity or frequency, or that the product is less effective than previously thought, or problems with the facility where the product is
manufactured, a regulatory agency may impose restrictions relative to that product or the manufacturing facility, including requiring recall or withdrawal of the product from
the market or suspension of manufacturing.

If  we  fail  to  comply  with  applicable  regulatory  requirements  following  approval  of  any  of  our  product  candidates  or  during  product  development,  or  if  we  later  discovery
previously unknown safety, efficacy, or manufacturing issues, the following may result:

● restrictions  on  manufacturing,  distribution,  marketing,  or  labeling  of  such  products,  including  restrictions  on  the  indication  or  approved  patient  population,  and

required additional warnings, such as black box warnings, contraindications, and precautions;

● requirements to conduct post-marketing studies or clinical trials, or to institute risk mitigation strategies, such as REMS;
● issuance of corrective information;
● the product may become less competitive, we may face reputational harm, or we may face liability for any harm caused to patients or subjects;
● modifications on the way the product is administered;
● modifications on promotional pieces;
● issuance of warning, untitled, or cyber letters asserting that we are in violation of the law, or of safety alerts, Dear Healthcare Provider letters, press releases, or other

communications containing warnings or other safety information about the product;

● injunction or imposition civil or criminal penalties or monetary fines, restitution, or disgorgement of profits or revenues;
● suspension or withdrawal of regulatory approval;
● suspension or termination of any ongoing clinical studies;
● refusal to approve a pending marketing application, such as a BLA or supplements to a BLA submitted by us;
● seizure, detention, or recall of product;
● refusal to permit the import or export of our products; or
● refusal to allow us to enter into supply contracts, including government contracts, exclusion from federal healthcare programs, FDA debarment, consent decrees, or

corporate integrity agreements.

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The
occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenues.

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, that
could limit the marketability of our product candidates, or that could impose additional regulatory obligations on us. For example, a change in administration in the U.S. may
result in new, revised, postponed or frozen regulatory requirements and associated compliance obligations. Changes in medical practice and standard of care may also impact
the marketability of our product candidates. If we are slow or unable to adapt to changes in existing requirements, standards of care, or the adoption of new requirements or
policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and be subject to regulatory enforcement
action.

Should  any  of  the  above  actions  take  place,  they  could  adversely  affect  our  ability  to  achieve  or  sustain  profitability.  Further,  the  cost  of  compliance  with  post-approval
regulations may have a negative effect on our operating results and financial condition.

Risks related to manufacturing

We could experience production problems in our manufacturing facilities that result in delays in our development or commercialization programs or otherwise adversely
affect our business.

We are susceptible to production interruptions that may impede our ability to manufacture cell and gene therapy products and produce an adequate product supply to support
clinical  trials  and  potentially  future  commercialization.  Several  factors  could  cause  production  interruptions,  including  equipment  malfunctions,  facility  contamination,  raw
material shortages or contamination, natural disasters, public health emergencies such as the COVID-19 pandemic, disruption in utility services, human error, or disruptions in
the operations of our suppliers. Our products and product candidates are biologic drugs requiring processing steps that are more complex than those required for most chemical
pharmaceuticals. We characterize our processes and products, and perform testing to ensure the safety, quality and efficacy of each product produced. While we take significant
measures to fully understand and characterize each product, the steps we take may not be sufficient to ensure that a given lot will perform in the intended manner.

There are several risks specific to the manufacturing process for EB-101 which require close attention. As an autologous product there are challenges associated with viability
of biopsies as an incoming material. Due to variables such as the fragility of RDEB skin and site of the biopsy, initiation of autologous keratinocyte growth and expansion can
be  challenging  or  may  be  extended  beyond  the  scheduled  timing.  Another  concern  during  manufacturing  is  the  slowing  of  cell  proliferation,  resulting  in  extended
manufacturing time. If pre-release criteria are not met, the production process must be stopped and a new biopsy must be obtained. If release criteria are out of range, epidermal
sheets must be discarded and the manufacturing process must be repeated.

We currently do not have a backup manufacturer to supply clinical trial material for EB-101. An alternative manufacturer would need to be qualified, through regulatory filings,
which  could  result  in  delays  to  our  clinical  trial  timeline.  The  regulatory  authorities  also  may  require  additional  clinical  trials  if  a  new  manufacturer  is  relied  upon  for
commercial production. Switching manufacturers may involve substantial costs and could result in a delay in our desired clinical and commercial timelines.

Accordingly, we employ multiple steps to control our manufacturing process to assure that the products or product candidate is made strictly and consistently in compliance
with the process. Problems with the manufacturing process, including even minor deviations from the normal process, could result in product defects or manufacturing failures
that result in lot failures, product recalls, product liability claims, or insufficient inventory. We may encounter problems achieving adequate quantities and quality of clinical
grade materials that meet FDA, EU or other applicable standards or specifications with consistent and acceptable production yields and costs. In addition, the FDA, EMA and
other foreign regulatory authorities may require us to submit samples of any lot of any approved product together with the protocols showing the results of applicable tests at
any  time.  Under  some  circumstances,  the  FDA,  EMA  or  other  foreign  regulatory  authorities  may  require  that  we  not  distribute  a  lot  until  the  agency  authorizes  its  release.
Slight deviations in the manufacturing process, including those affecting quality attributes and stability, may result in unacceptable changes in the product that could result in lot
failures or product recalls for approved and marketed products.

Lot failures or product recalls could cause us to delay product launches or clinical trials, which could be costly to us and otherwise harm our business, financial condition,
results of operations and prospects. We also may encounter problems hiring and retaining the experienced scientific, quality control and manufacturing personnel needed to
operate  our  manufacturing  process,  which  could  result  in  delays  in  our  production  or  difficulties  in  maintaining  compliance  with  applicable  regulatory  requirements. Any
problems in our manufacturing process or facilities could make us a less attractive collaborator for potential partners, including larger pharmaceutical companies and academic
research  institutions,  which  could  limit  our  access  to  additional  attractive  development  programs.  Problems  in  our  manufacturing  process  including  in  internal  and  external
facilities providing supply necessary for manufacturing or challenges with procuring supplies, such as due to global trade policies, also could restrict our ability to meet clinical
trial supply demand, and eventually market demand for any product candidates for which we may receive marketing approval. Disruptions in our manufacturing process may
delay or disrupt our commercialization efforts.

33

 
 
 
 
 
 
 
 
 
 
If we or any of our vendors, contract laboratories or suppliers are found to be out of compliance with cGMP, we may experience delays or disruptions in manufacturing
while  we  implement  corrective  actions  or  work  with  these  third  parties  to  remedy  the  violation  or  while  we  work  to  identify  suitable  replacement  vendors,  contract
laboratories or suppliers.

To obtain regulatory approval for commercial manufacturing, we will need to continue to ensure that all of our processes, methods and equipment are compliant with cGMP
and perform extensive audits of vendors, contract laboratories and suppliers. The cGMP requirements govern quality control of the manufacturing process and documentation
policies and procedures. Complying with cGMP requires us to expend time, money and effort in production, record keeping and quality control to assure that the product meets
applicable specifications and other requirements. If we fail to comply with these requirements, we would be subject to possible regulatory action and may not be permitted to
sell any products that we may develop.

We may rely on third parties to conduct aspects of our product manufacturing, and these third parties may not perform satisfactorily. We may rely on third parties to produce
certain materials for our product candidates and, therefore, we can control only certain aspects of their activities.

We and our third-party suppliers, laboratories, and manufacturers may be unable to comply with our specifications, cGMP 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 we or 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  may  include  the  temporary  or  permanent  suspension  of  a  clinical  trial  or  commercial  sales  or  the  temporary  or  permanent  closure  of  a  facility. Any  such
remedial measures imposed upon or by us or third parties with whom we contract could materially harm our business. Any delays in obtaining products 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.

We have manufacturing agreements with third parties that provide for, among other things, production of product candidates for our current and future early-stage clinical trials.
Under  certain  circumstances,  the  other  party  is  entitled  to  terminate  its  arrangement  with  us.  If  we  need  to  enter  into  alternative  arrangements,  it  could  delay  our  product
development activities. Our reliance on third parties for certain manufacturing activities will reduce our control over these activities but will not relieve us of our responsibility
to ensure compliance with all required regulations. If a third party does not successfully carry out its contractual duties, meet expected deadlines or manufacture our product
candidates in accordance with regulatory requirements, or if there are disagreements between us and any such third party, we will not be able to complete, or may be delayed in
completing, the preclinical studies required to support future IND submissions and the clinical trials required for approval of our product candidates. In such instances, we may
need  to  enter  into  an  appropriate  replacement  third-party  relationship,  which  may  not  be  readily  available  or  on  acceptable  terms,  which  would  cause  additional  delay  or
increased expense prior to the approval of our product candidates and would thereby have a material adverse effect on our business, financial condition, results of operations
and prospects.

In addition, if the FDA or a comparable foreign regulatory authority does not approve our or a third party’s facilities for the manufacture of our product candidates or if it
withdraws  any  such  approval  in  the  future,  we  may  need  to  find  alternative  manufacturing  facilities,  which  would  significantly  impact  our  ability  to  develop,  obtain  and
maintain regulatory approval for or market our product candidates, if approved. 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. We  may  not  succeed  in  our  efforts  to  establish  manufacturing  relationships  or  other  alternative  arrangements  for  any  of  our  product
candidates, components, and programs. For example, our product candidates may compete with other products and product candidates for access to manufacturing facilities.
There are a limited number of manufacturers that operate under cGMP regulations and that are both capable of manufacturing for us and willing to do so.

34

 
 
 
 
 
 
 
 
The  manufacture  of  biologic  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 we or 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.

Our reliance on these third parties entails risks to which we would not be subject if we manufactured the product candidates ourselves, including:

● reduced control for certain aspects of manufacturing activities;
● reduced control over the protection of our trade secrets and know-how from misappropriation or inadvertent disclosure;
● inability to negotiate manufacturing agreements with third parties under commercially reasonable terms;

reliance on the third party for regulatory compliance and quality assurance;

● termination or nonrenewal of manufacturing and service agreements with third parties in a manner or at a time that is costly or damaging to us; and
● disruptions  to  the  operations  of  our  third-party  manufacturers  and  service  providers  caused  by  conditions  unrelated  to  our  business  or  operations,  including  the

bankruptcy of the manufacturer or service provider.

Any of these events could lead to clinical trial delays or failure to obtain regulatory approval or impact our ability to successfully commercialize future product candidates.
Some of these events could be the basis for FDA action or action of equivalent competent authorities in foreign jurisdictions, including injunction, recall, seizure or total or
partial  suspension  of  product  manufacturing.  Failure  to  comply  with  ongoing  regulatory  requirements  could  cause  us  to  suspend  production  or  put  in  place  costly  or  time-
consuming remedial measures.

If  any  inspection  or  audit  by  regulatory  authorities  identifies  a  failure  to  comply  with  applicable  regulations,  or  if  a  violation  of  product  specifications  or  applicable
regulations occurs independent of such an inspection or audit, the relevant regulatory authority may require remedial measures that may be costly or time-consuming 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 manufacturing
facility.

Regulatory authorities may inspect or audit the manufacturing facilities for our products and product candidates at any time. Any such remedial measures imposed upon us
could materially harm our business, financial condition, results of operations and prospects. If we fail to comply with applicable cGMP regulations, FDA and foreign regulatory
authorities could impose regulatory sanctions including, among other things, refusal to approve a pending application for a new product candidate or suspension or revocation
of a pre-existing approval. Such an occurrence may cause our business, financial condition, results of operations and prospects to be materially harmed. Additionally, if supply
from our facility is interrupted, there could be a significant disruption in commercial supply of any of our product candidates for which we obtain marketing approval, and in
clinical supply for our product candidates.

If we, our collaborators, or any third-party manufacturers 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 harm our business.

We, our collaborators, and any third-party manufacturers we engage are subject to numerous environmental, health and safety laws and regulations, including those governing
laboratory procedures and the generation, handling, use, storage, treatment, manufacture, transportation and disposal of, and exposure to, hazardous materials and wastes, as
well as laws and regulations relating to occupational health and safety. Our operations involve the use of hazardous and flammable materials, including chemicals and biologic
materials. Our operations also produce hazardous waste products. 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. We also could incur significant costs associated with civil or criminal fines and penalties.

Although  we  maintain  general  liability  insurance  and  workers’  compensation  insurance  for  certain  costs  and  expenses  that  we  may  incur  due  to  injuries  to  our  employees
resulting from the use of hazardous materials or other work-related injuries, this insurance may not provide adequate coverage against potential liabilities. We do not maintain
insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biologic and hazardous materials.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations, which have tended to become more
stringent over time. These current or future laws and regulations may impair our research, development, or production efforts. Failure to comply with these laws and regulations
also may result in substantial fines, penalties or other sanctions or liabilities, which could harm our business, financial condition, results of operations and prospects.

The widespread outbreak of an illness, communicable disease, or any other public health crisis could adversely affect our business, results of operations and financial
condition.

We could be negatively impacted by the widespread outbreak of an illness, communicable disease, or any other public health crisis that results in economic or trade disruptions,
including the disruption of global supply chains. The COVID-19 pandemic negatively impacted the economy on a global, national, and local level, disrupted global supply
chains,  and  created  volatility  and  disruption  of  financial  markets.  Responses  from  governmental  authorities  and  companies  to  reduce  the  spread  of  COVID-19  affected
economic  activity  through  various  containment  measures  including,  among  others,  business  closures,  work  stoppages,  quarantine  and  work-from-home  guidelines,  limiting
capacity at public spaces and events, vaccination requirements, or restrictions of global and regional travel. Another outbreak of an illness, a communicable disease, or any
other public health crisis, and any resulting impacts, such as an extended period of global supply chain and/or economic disruption, labor shortages, or government-mandated
actions in response to such public health crisis could materially affect our business, results of operations, access to sources of liquidity, and financial condition.

Risks related to our reliance on third-parties

We expect to rely on third parties to conduct some or all aspects of our viral vector production, drug product manufacturing, research and preclinical, and clinical testing,
and these third parties may not perform satisfactorily.

We do not expect to independently conduct all aspects of our viral vector production, drug product manufacturing and distribution, research and preclinical, and clinical testing.
We currently rely, and expect to continue to rely, on third parties with respect to these matters. In some cases, these third parties are academic, research or similar institutions
that may not apply the same quality control protocols utilized in certain commercial settings.

Our  reliance  on  these  third  parties  for  research  and  development  activities  reduces  our  control  over  these  activities  but  does  not  relieve  us  of  our  responsibility  to  ensure
compliance with all required regulations and study protocols. For example, for product candidates that we develop and commercialize on our own, we remain responsible for
ensuring that each of our IND-enabling studies and clinical studies are conducted in accordance with the study plan and protocols, and that our viral vectors and drug products
are manufactured in accordance with GMP as applied in the relevant jurisdictions. We must also ensure that our preclinical trials are conducted in accordance with GLPs, 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. Regulatory authorities
enforce these requirements through periodic inspections. If we or any of our third-party service providers fail to comply with applicable regulatory requirements, we or they
may be subject to enforcement or other legal actions, the data generated in our trials or manufacturing development may be deemed unreliable, and the FDA or comparable
foreign regulatory authorities may require us to perform additional studies and manufacturing development. If these third parties do not successfully carry out their contractual
duties, meet expected deadlines, conduct our studies in accordance with regulatory requirements or our stated study plans and protocols, or manufacture our viral vectors and
drug products in accordance with cGMP, or 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 will not be able to complete, or may be delayed in completing, the preclinical and clinical studies and manufacturing
process validation activities required to support future IND, MAA and BLA submissions and approval of our product candidates.

Any  of  these  third  parties  may  terminate  their  engagements  with  us  at  any  time.  If  we  need  to  enter  into  alternative  arrangements,  it  could  delay  our  product  development
activities. Any of these events could lead to clinical study delays or failure to obtain regulatory approval or impact our ability to successfully commercialize future products.
Some of these events could be the basis for FDA action, including injunction, recall, seizure or total or partial suspension of production.

36

 
 
 
 
 
 
 
 
 
 
Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be
misappropriated or disclosed.

Because we rely on third parties to manufacture our vectors and our product candidates, and because we collaborate with various organizations and academic institutions on the
advancement of our cell and gene therapy platform, we must, at times, share trade secrets with them. We seek to protect our proprietary technology in part by entering into
confidentiality  agreements  and,  if  applicable,  material  transfer  agreements,  collaborative  research  agreements,  consulting  agreements  or  other  similar  agreements  with  our
collaborators, advisors, employees, and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third
parties to use or disclose our confidential information, such as trade secrets. Despite the contractual provisions employed when working with third parties, the need to share
trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology
of others, or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s
discovery of our trade secrets or other unauthorized use or disclosure would impair our competitive position and may have a material adverse effect on our business.

In addition, these agreements typically restrict the ability of our collaborators, advisors, employees, and consultants to publish data potentially relating to our trade secrets. Our
academic collaborators typically have rights to publish data, provided that we are notified in advance and may delay publication for a specified time in order to secure our
intellectual property rights arising from the collaboration. In other cases, publication rights are controlled exclusively by us, although in some cases we may share these rights
with  other  parties.  We  also  conduct  joint  research  and  development  programs  that  may  require  us  to  share  trade  secrets  under  the  terms  of  our  research  and  development
partnerships or similar agreements. Despite our efforts to protect our trade secrets, our competitors may discover our trade secrets, either through breach of these agreements,
independent  development  or  publication  of  information  including  our  trade  secrets  in  cases  where  we  do  not  have  proprietary  or  otherwise  protected  rights  at  the  time  of
publication. A competitor’s discovery of our trade secrets would impair our competitive position and have an adverse impact on our business.

Risks related to with commercializing our product candidates

If we do not obtain the necessary U.S. or worldwide regulatory approvals to commercialize EB-101, we will not be able to sell EB-101.

If  we  cannot  obtain  regulatory  approval  for  EB-101,  we  will  not  be  able  to  generate  revenue  from  this  product  candidate. As  a  result,  our  ability  to  generate  revenue  from
product commercialization may be further delayed. We cannot assure you that we will receive the approvals necessary to commercialize EB-101 or any other product candidate
we may develop in the future. In order to obtain FDA approval of EB-101 or any other product candidate requiring FDA approval, we must successfully complete an FDA BLA
review. Obtaining FDA approval of any other product candidate generally requires significant research and testing, referred to as preclinical studies, as well as human tests,
referred  to  as  clinical  trials.  Satisfaction  of  the  FDA’s  regulatory  requirements  typically  takes  many  years,  depends  upon  the  type,  complexity  and  novelty  of  the  product
candidate and requires substantial resources for research, development and testing. We cannot predict whether our research and clinical approaches will result in products that
the  FDA  considers  safe  for  humans  and  effective  for  indicated  uses.  The  FDA  has  substantial  discretion  in  the  product  approval  process  and  may  require  us  to  conduct
additional  preclinical  and  clinical  testing  or  to  perform  post-marketing  studies.  The  approval  process  may  also  be  delayed  by  changes  in  government  regulation,  future
legislation or administrative action or changes in FDA policy that occur prior to or during our regulatory review. Delays in obtaining regulatory approvals may:

● delay commercialization of, and our ability to derive product revenues from, EB-101 or any other product candidate;
● impose costly procedures on us; and
● diminish any competitive advantages that we may otherwise enjoy.

37

 
 
 
 
 
 
 
 
 
 
 
 
Even if we comply with all FDA requests, the FDA may ultimately reject our BLA. In addition, the FDA could determine that we must test additional subjects or require that
we conduct further studies with more subjects. We may never obtain regulatory approval for EB-101, or any other future potential product candidate. Failure to obtain FDA
approval  of  any  of  our  product  candidates  will  severely  undermine  our  business  by  leaving  us  without  the  ability  to  generate  additional  accretive  revenues.  There  is  no
guarantee that we will ever be able to develop or acquire other product candidates. In foreign jurisdictions, we must receive approval from the appropriate regulatory authorities
before we can commercialize any products or product candidates outside the U.S. Foreign regulatory approval processes generally include all of the risks and uncertainties
associated with the FDA approval procedures described above. We cannot assure you that we will receive the approvals necessary to commercialize any product candidate for
sale outside the U.S.

Even  if  we  receive  regulatory  approval  for  EB-101,  our  lead  drug  candidate,  we  may  not  be  able  to  successfully  commercialize  the  product  and  the  revenue  that  we
generate from its sales, if any, may be limited.

If  approved  for  marketing,  the  commercial  success  of  EB-101  will  depend  upon  the  product’s  acceptance  by  the  medical  community,  including  physicians,  patients  and
healthcare payors. The degree of market acceptance for our drug candidate will depend on a number of factors, including:

● actual and perceived efficacy and safety of EB-101;
● relative convenience, dosing burden and ease of administration;
● potential or perceived advantages or disadvantages over alternative treatments;
● potential post-marketing commitments imposed by regulatory authorities, such as patient registries;
● strength of sales, marketing and distribution support;
● price of our future products, both in absolute terms and relative to alternative treatments;
● the effect of current and future healthcare laws on EB-101; and
● availability of coverage and reimbursement from government and other third party payers.

If our drug candidate is approved, but does not achieve an adequate level of acceptance by physicians, healthcare payors and patients, we may not generate sufficient revenue
and we may not be able to achieve or sustain profitability. Our efforts to educate the medical community and third-party payors on the benefits of our drug candidates may
require significant resources and may never be successful.

Our drug candidates are subject to the risks of failure inherent in the development of pharmaceutical products based on new technologies, and our failure to develop safe
and commercially viable drugs would severely limit our ability to become profitable or to achieve significant revenues.

We may be unable to successfully commercialize our product candidates if some or all of our product candidates are found to be unsafe or ineffective or otherwise fail to meet
applicable  regulatory  standards  or  receive  necessary  regulatory  clearances. Additionally,  our  product  candidates  may  be  deemed  too  difficult  to  develop  into  commercially
viable drugs. We may encounter difficulty in manufacturing or marketing our product candidates on a large scale, and proprietary rights of third parties may preclude us from
marketing  our  drug  candidates.  Moreover,  competitors  may  be  able  to  market  superior  or  equivalent  drugs  successfully.  Failure  to  successfully  commercialize  our  product
candidates would have a material adverse effect on our business.

We  may  be  unable  to  successfully  develop,  market,  or  commercialize  our  products  or  our  product  candidates  without  establishing  new  relationships  and  maintaining
current  relationships  and  our  ability  to  successfully  commercialize,  and  market  our  product  candidates  could  be  limited  if  a  number  of  these  existing  relationships  are
terminated.

Our strategy for the research, development and commercialization of our potential pharmaceutical products may require us to enter into various arrangements with corporate
and academic collaborators, licensors, licensees and others, in addition to our existing relationships with other parties. Specifically, we may seek to joint venture, sublicense or
enter into other marketing arrangements with parties that have an established marketing capability, or we may choose to pursue the commercialization of such products on our
own. We may, however, be unable to establish such additional collaborative arrangements, license agreements, or marketing agreements as we may deem necessary to develop,
commercialize and market our potential pharmaceutical products on acceptable terms. Furthermore, since we maintain and establish arrangements or relationships with third
parties, our business may depend upon the successful performance by these third parties of their responsibilities under those arrangements and relationships. If we are unwilling
or unable to perform our obligations under any license or collaboration arrangement, a third party may have the right to terminate such arrangement with us.

38

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We are subject to extensive governmental regulation, which increases our cost of doing business and may affect our ability to commercialize any new products that we may
develop.

The  FDA  and  comparable  agencies  in  foreign  countries  impose  substantial  requirements  upon  the  introduction  of  pharmaceutical  products  through  lengthy  and  detailed
laboratory, preclinical and clinical testing procedures and other costly and time-consuming procedures to establish safety and efficacy. All of our drugs and drug candidates
require receipt and maintenance of governmental approvals for commercialization. Preclinical and clinical trials and manufacturing of our drug candidates will be subject to the
rigorous testing and approval processes of the FDA and corresponding foreign regulatory authorities. Satisfaction of these requirements typically takes a significant number of
years and can vary substantially based upon the type, complexity, and novelty of the product.

Due to the time-consuming and uncertain nature of the drug candidate development process and the governmental approval process described above, we cannot be certain when
we, independently or with our collaborative partners, might submit a BLA for FDA or other regulatory review. Further, our ability to commence and/or complete development
projects  will  be  subject  to  our  ability  to  raise  enough  funds  to  pay  for  the  development  costs  of  these  projects.  Government  regulation  also  affects  the  manufacturing  and
marketing  of  pharmaceutical  products.  Government  regulations  may  delay  marketing  of  our  potential  drugs  for  a  considerable  or  indefinite  period  of  time,  impose  costly
procedural requirements upon our activities and furnish a competitive advantage to larger companies or companies more experienced in regulatory affairs. Delays in obtaining
governmental regulatory approval could adversely affect our marketing as well as our ability to generate significant revenues from commercial sales.

Our  drug  candidates  may  not  receive  FDA  or  other  regulatory  approvals  on  a  timely  basis  or  at  all.  Moreover,  if  regulatory  approval  of  a  drug  candidate  is  granted,  such
approval may impose limitations on the indicated use for which such drug may be marketed. Even if we obtain initial regulatory approvals for our drug candidates, our drugs
and our manufacturing facilities would be subject to continual review and periodic inspection, and later discovery of previously unknown problems with a drug, manufacturer
or facility may result in restrictions on the marketing or manufacture of such drug, including withdrawal of the drug from the market. The FDA and other regulatory authorities
stringently apply regulatory standards and failure to comply with regulatory standards can, among other things, result in fines, denial or withdrawal of regulatory approvals,
product recalls or seizures, operating restrictions, and criminal prosecution.

We may incur substantial product liability expenses due to the use or misuse of our products for which we may be unable to obtain insurance coverage.

Our  business  exposes  us  to  potential  liability  risks  that  are  inherent  in  the  testing,  manufacturing,  and  marketing  of  pharmaceutical  products. These  risks  will  expand  with
respect to our drug candidates, if any, that receive regulatory approval for commercial sale and we may face substantial liability for damages in the event of adverse side effects,
including injury or death, or product defects identified with any of our products that are used in clinical tests or marketed to the public. Product liability actions can also have
regulatory consequences, including the withdrawal of clinical trial participants and potential termination of clinical trial sites or entire clinical programs, and the initiation of
investigations, and enforcement actions by regulators, product recalls, withdrawals, revocation of approvals, or labeling, marketing, or promotional restrictions.

Product liability insurance for the biotechnology industry is generally expensive, if available at all, and as a result, we may be unable to obtain insurance coverage at acceptable
costs or in a sufficient amount in the future, if at all. We may be unable to satisfy any claims for which we may be held liable as a result of the use or misuse of products which
we developed, manufactured, or sold and any such product liability claim could adversely affect our business, operating results, or financial condition.

Intense competition may limit our ability to successfully develop and market commercial products.

The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. Our competitors in the U.S. and elsewhere
are  numerous  and  include,  among  others,  major  multinational  pharmaceutical  and  chemical  companies,  specialized  biotechnology  firms  and  universities  and  other  research
institutions.  Many  of  our  competitors  have  and  employ  greater  financial  and  other  resources,  including  larger  research  and  development,  marketing,  and  manufacturing
organizations. As a result, our competitors may successfully develop technologies and drugs that are more effective or less costly than any that we are developing, which could
render our technology and future products obsolete and noncompetitive.

39

 
 
 
 
 
 
 
 
 
 
 
In  addition,  some  of  our  competitors  have  greater  experience  than  we  do  in  conducting  preclinical  and  clinical  trials  and  obtaining  FDA  and  other  regulatory  approvals.
Accordingly, our competitors may succeed in obtaining FDA or other regulatory approvals for drug candidates more rapidly than we can. Companies that complete clinical
trials, obtain required regulatory agency approvals, and commence commercial sale of their drugs before their competitors may achieve a significant competitive advantage.
Drugs  resulting  from  our  research  and  development  efforts  or  from  our  joint  efforts  with  collaborative  partners  therefore  may  not  be  commercially  competitive  with  our
competitors’ existing products or products under development.

Our products and product candidates may face competition sooner than anticipated.

Our products and product candidates may face competition from other products that are the same as or similar to ours. If the FDA or comparable foreign regulatory authorities
approve biosimilar versions of our products or product candidates, or such authorities do not grant our products appropriate or anticipated periods of regulatory exclusivity, the
sales of our products could be adversely affected. Moreover, even if we receive periods of regulatory exclusivity, that exclusivity may not adequately protect us from biosimilar
or other product competition. There may also be changes in regulatory exclusivity policies. For example, there have been efforts to decrease the biologic period of exclusivity to
a shorter timeframe. Future proposed budgets, international trade agreements and other arrangements or proposals may affect periods of exclusivity. If another company pursues
approval of a product that is biosimilar to any biologic product for which we receive FDA approval, we may need to pursue costly and time-consuming patent infringement
actions, which may include certain statutorily specified regulatory steps before an infringement action may be brought. Biosimilar applicants may also be able to bring an action
for declaratory judgment concerning our patents, requiring that we spend time and money defending the action.

Our  ability  to  successfully  develop  and  commercialize  our  drug  candidates  will  substantially  depend  upon  the  availability  of  reimbursement  funds  for  the  costs  of  the
resulting drugs and related treatments.

Market  acceptance  and  sales  of  our  product  candidates  may  depend  on  coverage  and  reimbursement  policies  and  health  care  reform  measures.  Decisions  about  formulary
coverage as well as levels at which government authorities and third-party payors, such as private health insurers and health maintenance organizations, reimburse patients for
the price they pay for our products as well as levels at which these payors pay directly for our products, where applicable, could affect whether we are able to commercialize
these products. We cannot be sure that reimbursement will be available for any of these products. Also, we cannot be sure that coverage or reimbursement amounts will not
reduce  the  demand  for,  or  the  price  of,  our  products.  We  have  not  commenced  efforts  to  have  our  product  candidates  reimbursed  by  government  or  third-party  payors.  If
coverage and reimbursement are not available or are available only at limited levels, we may not be able to commercialize our products. In recent years, officials have made
numerous proposals to change the health care system in the U.S. These proposals include measures that would limit or prohibit payments for certain medical treatments or
subject the pricing of drugs to government control. In addition, in many foreign countries, particularly the countries of the European Union, the pricing of prescription drugs is
subject to government control. If our products are or become subject to government regulation that limits or prohibits payment for our products, or that subjects the price of our
products to governmental control, we may not be able to generate revenue, attain profitability or commercialize our products.

As a result of legislative proposals and the trend towards managed health care in the U.S., third-party payors are increasingly attempting to contain health care costs by limiting
both coverage and the level of reimbursement of new drugs. They may also impose strict prior authorization requirements and/or refuse to provide any coverage of uses of
approved products for medical indications other than those for which the FDA has granted market approvals. As a result, significant uncertainty exists as to whether and how
much third-party payors will reimburse patients for their use of newly approved drugs, which in turn will put pressure on the pricing of drugs.

The market may not accept any pharmaceutical products that we develop, thereby materially impairing our ability to generate revenue from such products.

The products that we are attempting to develop may compete with drugs manufactured and marketed by other pharmaceutical companies. The degree of market acceptance of
any drugs developed by us will depend on a number of factors, including the establishment and demonstration of the clinical efficacy and safety of our drug candidates, the
potential advantage of our drug candidates over existing therapies and the reimbursement policies of government and third-party payors. Physicians, patients, or the medical
community in general may not accept or use any drugs that we may develop independently or with our collaborative partners and if they do not, our business could suffer.

40

 
 
 
 
 
 
 
 
 
 
Adverse public perception of gene therapy products may negatively affect demand for, or regulatory approval of, our product candidates.

Our product candidates involve altering genes, and the clinical and commercial success of our product candidates will depend in part on public acceptance of the use of gene
altering therapies for the treatment of genetic diseases. Public attitude may be influenced by claims that gene therapy is unsafe, unethical, or immoral, and, as a result, our
product candidates may not gain the acceptance of the public or the medical community. Negative public reaction to gene therapy in general could result in greater government
regulation and stricter labeling requirements of gene therapy products, including any of our product candidates, and could cause a decrease in the demand for any products we
may develop. Adverse public opinion also may adversely affect our ability to enroll patients in clinical trials.

Healthcare reform measures could hinder or prevent our product candidates’ commercial success.

Any government-adopted reform measures could adversely affect the pricing of healthcare products and services in the U.S. or internationally and the amount of reimbursement
available  from  governmental  agencies  or  other  third-party  payors.  The  continuing  efforts  of  the  U.S.  and  foreign  governments,  insurance  companies,  managed  care
organizations and other payors of health care services to contain or reduce health care costs may adversely affect our ability to set prices for our products which we believe are
fair, restrict coverage and reimbursement, or require payment of increased rebates and our ability to generate revenues and achieve and maintain profitability.

New laws, regulations and judicial decisions, or new interpretations of existing laws, regulations, and decisions, that relate to healthcare availability, methods of delivery or
payment for products and services, or sales, marketing, or pricing, may limit our potential revenue, and we may need to revise our research and development programs. The
pricing and reimbursement environment may change in the future and become more challenging due to several reasons including new healthcare legislation or regulation and
fiscal challenges faced by government health administration authorities. Specifically, in both the U.S. and some foreign jurisdictions, there have been a number of legislative
and regulatory proposals to change the health care system in ways that could affect our ability to sell our products profitably.

We also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, either in the United
States or abroad.

We  may  be  subject,  directly  or  indirectly,  to  federal,  state,  and  foreign  healthcare  laws  and  regulations,  including  fraud  and  abuse  laws,  false  claims  laws  and  health
information privacy and security laws. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.

If  we  obtain  FDA  approval  for  any  of  our  product  candidates  and  begin  commercializing  those  products  in  the  United  States,  our  operations  will  be  directly,  or  indirectly
through our prescribers, customers, and purchasers, subject to various federal and state laws and regulations, including, without limitation, the federal Anti-Kickback Statute,
the federal civil and criminal false claims act, the civil monetary penalties statute, HIPAA, and the Physician Payments Sunshine Act and regulations. These laws are further
described in the U.S. Biologic Products Development Process section of this annual report. These laws will impact, among other things, our proposed sales, marketing, and
educational programs. In addition, we may be subject to data privacy laws by both the federal government and the states in which we conduct our business. Failure to comply
with these laws could result in penalties, including civil and criminal penalties, damages, fines, the curtailment or restructuring of operations, the exclusion from participation in
federal and state healthcare programs, debarment from government contracting or refusal of orders under existing contracts, corporate integrity agreements or consent decrees,
disgorgement,  contractual  damages,  reputational  harm,  diminished  profits  and  future  earnings,  and  imprisonment.  Furthermore,  efforts  to  ensure  that  business  activities  and
business arrangements comply with applicable healthcare laws and regulations can be costly. Comparable laws and regulations apply internationally.

41

 
 
 
 
 
 
 
 
 
 
We are subject to extensive laws and regulations related to data privacy, and our failure to comply with these laws and regulations could harm our business.

Numerous foreign, federal, and state laws and regulations govern collection, dissemination, use and confidentiality of personally identifiable health information, including state
privacy  and  confidentiality  laws  (including  state  laws  requiring  disclosure  of  breaches),  HIPAA  and  the  European  Union’s  General  Data  Protection  Regulation  (“GDPR”).
These laws and regulations are increasing in complexity and number and may change frequently and sometimes conflict.

HIPAA  establishes  a  set  of  national  privacy  and  security  standards  for  the  protection  of  individually  identifiable  health  information,  including  protected  health  information
(“PHI”),  by  health  plans,  certain  healthcare  clearinghouses  and  healthcare  providers  that  submit  certain  covered  transactions  electronically,  or  covered  entities,  and  their
“business  associates,”  which  are  persons  or  entities  that  perform  certain  services  for,  or  on  behalf  of,  a  covered  entity  that  involve  creating,  receiving,  maintaining  or
transmitting PHI. While we are not currently a covered entity or business associate under HIPAA, we may receive identifiable information from these entities. Failure to protect
this information properly could subject us to HIPAA’s criminal penalties, which may include fines up to $250,000 per violation and/or imprisonment.

GDPR imposes numerous requirements on entities that process personal data in the context of an establishment in the European Economic Area (“EEA”) or that process the
personal  data  of  data  subjects  who  are  located  in  the  EEA. These  requirements  include,  for  example,  establishing  a  basis  for  processing,  providing  notice  to  data  subjects,
developing procedures to vindicate expanded data subject rights, implementing appropriate technical and organizational measures to safeguard personal data, and complying
with restrictions on the cross-border transfer of personal data from the EEA to countries that the European Union does not consider to have in place adequate data protection
legislation, such as the United States. GDPR additionally establishes heightened obligations for entities that process “special categories” of personal data, such as health data.
Nearly all clinical trials involve the processing of these “special categories” of personal data, and thus processing of personal data collected during the course of clinical trials is
subject to heightened protections under GDPR.

Moreover, California adopted the California Consumer Privacy Act of 2018 (“CCPA”), which went into effect in January 2020. The CCPA has been characterized as the first
“GDPR-like” privacy statute to be enacted in the United States because it mirrors a number of the key provisions of the GDPR. The CCPA establishes a new privacy framework
for  covered  businesses  in  the  State  of  California,  by  creating  an  expanded  definition  of  personal  information,  establishing  new  data  privacy  rights  for  consumers  imposing
special  rules  on  the  collection  of  consumer  data  from  minors,  and  creating  a  new  and  potentially  severe  statutory  damages  framework  for  violations  of  the  CCPA  and  for
businesses that fail to implement reasonable security procedures and practices to prevent data breaches.

The legislative and regulatory landscape for privacy and data security continues to evolve, and there has been an increasing focus on privacy and data security issues which may
affect  our  business.  Failure  to  comply  with  current  and  future  laws  and  regulations  could  result  in  government  enforcement  actions  (including  the  imposition  of  significant
penalties), criminal and/or civil liability for us and our officers and directors, private litigation and/or adverse publicity that negatively affects our business.

Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer.

In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary business information and that of our suppliers and
business partners, as well as personally identifiable information of clinical trial participants and employees. Similarly, our business partners and third-party providers possess
certain  of  our  sensitive  data. The  secure  maintenance  of  this  information  is  critical  to  our  operations  and  business  strategy.  Despite  our  security  measures,  our  information
technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance, or other disruptions. Any such breach could compromise
our networks and the information stored there could be accessed, publicly disclosed, lost, or stolen. If such an event were to occur and cause interruptions in our operations, it
could result in a disruption of our development programs and our business operations, whether due to a loss of our trade secrets or other proprietary information or other similar
disruptions. For example, the loss of clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly increase
our costs to recover or reproduce the data. To the extent that any disruption or 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, our competitive position could be harmed, and the further development and commercialization of
our product candidates could be delayed.

42

 
 
 
 
 
 
 
 
 
 
Our business could suffer if we lose the services of, or fail to attract, key personnel.

We  depend  highly  upon  the  efforts  of  our  senior  management.  The  loss  of  the  services  of  these  individuals  could  delay  or  prevent  the  achievement  of  our  research,
development, marketing, or product commercialization objectives. We do not have employment contracts with our other key personnel. We do not maintain any “key-man”
insurance policies on any of our key employees and we do not intend to obtain such insurance. In addition, due to the specialized scientific nature of our business, we are highly
dependent  upon  our  ability  to  attract  and  retain  qualified  scientific  and  technical  personnel  and  consultants. There  is  intense  competition  among  major  pharmaceutical  and
chemical  companies,  specialized  biotechnology  firms  and  universities  and  other  research  institutions  for  qualified  personnel  in  the  areas  of  our  activities  and  we  may  be
unsuccessful in attracting and retaining these personnel.

We have experienced turnover in our senior management team, and the loss of one or more of our executive officers or key employees or an inability to attract and retain
highly skilled employees could adversely affect our business.

Our  success  depends  largely  upon  the  continued  services  of  our  key  executive  officers.  We  have  in  the  past  and  may  in  the  future  experience  changes  in  our  executive
management  team  resulting  from  the  departure  of  executives  or  subsequent  hiring  of  new  executives,  which  may  be  disruptive  to  our  business. To  continue  to  develop  our
pipeline and execute our strategy, we also must attract and retain highly skilled personnel in our industry.

Trends toward managed health care, health technology assessment, and downward price pressures on medical products and services may limit our ability to profitably sell
any drugs that we may develop.

Lower prices for pharmaceutical products or reduced profitability may result from:

● third-party-payors’  increasing  challenges  to  the  prices  charged  for  medical  products  and  services,  including  by  limiting  coverage  and  reimbursement  and  requiring

payment of increased manufacturer rebates;

● the trend toward managed health care in the U.S. and the concurrent growth of Health Maintenance Organizations (“HMOs”) and similar organizations that can control

or significantly influence the purchase of healthcare services and products; and

● state, federal, and foreign legislative proposals to control drug prices, reform healthcare or reduce government insurance programs.

The  cost  containment  measures  that  healthcare  providers  are  instituting,  including  practice  protocols  and  guidelines  and  clinical  pathways,  and  the  effect  of  any  healthcare
reform, could limit our ability to profitably sell any drugs that we may successfully develop. Moreover, any future legislation or regulation, if any, relating to the healthcare
industry or third-party coverage and reimbursement, may cause our business to suffer.

Risks related to our intellectual property

Our rights to develop and commercialize our product candidates are subject to, in part, the terms and conditions of licenses granted to us by others.

We rely upon licenses to certain patent rights and proprietary technology from third parties that are important or necessary to the development of our technology and products,
including  technology  related  to  our  manufacturing  process  and  our  product  candidates.  These  and  other  licenses  may  not  provide  exclusive  rights  to  use  such  intellectual
property and technology in all relevant fields of use and in all territories in which we may wish to develop or commercialize our technology and products in the future. As a
result, we may not be able to prevent competitors from developing and commercializing competitive products in territories included in all of our licenses. These licenses may
also require us to grant back certain rights to licensors and to pay certain amounts relating to sublicensing patent and other rights under the agreement.

In some circumstances, particularly in-licenses with academic institutions, we may not have the right to control the preparation, filing and prosecution of patent applications, or
to maintain the patents, covering in-licensed technologies. Therefore, in those cases we cannot be certain that these patents and applications will be prosecuted, maintained and
enforced in a manner consistent with the best interests of our business. If our licensors fail to maintain such patents, or lose rights to those patents or patent applications, the
rights we have licensed may be reduced or eliminated and our right to develop and commercialize any of our products that are the subject of such licensed rights could be
adversely affected. In certain circumstances, we have or may license technology from third parties on a non-exclusive basis. In such instances, other licensees may have the
right to enforce our licensed patents in their respective fields, without our oversight or control. Those other licensees may choose to enforce our licensed patents in a way that
harms our interest, for example, by advocating for claim interpretations or agreeing on invalidity positions that conflict with our positions or our interest. In addition to the
foregoing, the risks associated with patent rights that we license from third parties will also apply to patent rights we may own in the future.

43

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Further, in many of our license agreements we are responsible for bringing any actions against any third party for infringing the patents we have licensed. Certain of our license
agreements  also  require  us  to  meet  development  milestones  to  maintain  the  license,  including  establishing  a  set  timeline  for  developing  and  commercializing  products  and
minimum  yearly  diligence  obligations  in  developing  and  commercializing  the  product.  Disputes  may  arise  regarding  intellectual  property  subject  to  a  licensing  agreement,
including:

● the scope of rights granted under the license agreement and other interpretation-related issues;
● the extent to which our technology and processes infringe intellectual property rights of the licensor that are not subject to the licensing agreement;
● the sublicensing of patent and other rights under our collaborative development relationships;
● our diligence obligations under the license agreement and what activities satisfy those diligence obligations;
● the inventorship or ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners; and
● the priority of invention of patented technology.

If any dispute over in-licensed intellectual property prevents or impairs our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to
successfully develop and commercialize the affected product candidates.

If we fail to comply with our obligations under these license agreements, or we are subject to a bankruptcy, the licensor may have the right to terminate the license, in which
event  we  would  not  be  able  to  develop,  manufacture,  or  market  products  covered  by  the  license  or  may  face  other  penalties  under  the  agreements.  Termination  of  these
agreements or reduction or elimination of our rights under these agreements may result in our 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. It is possible that such termination may occur even if
we believe that we have complied with our obligations under a license agreement, if a dispute arises between us and a licensor.

Furthermore, to the extent that the research resulting in certain of our licensed patent rights and technology was funded by the U.S. government, the government may have
certain rights, or march-in rights, to such patent rights and technology. When new technologies are developed with U.S. government funding, the U.S. government generally
obtains certain rights in any resulting patents, including a non-exclusive, royalty-free license authorizing the U.S. government, or a third party on its behalf, to use the invention
for non-commercial purposes. These rights may permit the government to disclose our confidential information to third parties and to exercise march-in rights to use or allow
third parties to use our licensed technology. The U.S. government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical
application  of  the  government-funded  technology,  because  action  is  necessary  to  alleviate  health  or  safety  needs,  to  meet  requirements  of  federal  regulations  or  to  give
preference to U.S. industry. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the United
States. Any exercise by the government, or a third party on its behalf, of such rights could harm our competitive position, business, financial condition, results of operations and
prospects.

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

Our  success  depends,  in  large  part,  on  our  and  our  licensors’  ability  to  obtain  and  maintain  patent  protection  in  the  United  States  and  other  countries  with  respect  to  our
proprietary product candidates and manufacturing technology. We and our licensors have sought, and we intend to seek in the future, to protect our proprietary positions by
filing patent applications in the United States and abroad related to many of our novel technologies and product candidates that are important to our business.

The patent prosecution process is expensive, time-consuming and complex, and we may not have and may not in the future be able to file, prosecute, maintain, enforce, or
license all necessary or desirable patent applications at a reasonable cost or in a timely manner. For example, in some cases, the work of certain academic researchers in the
gene therapy field has entered the public domain, which may compromise our ability to obtain patent protection for certain inventions related to or building upon such prior
work. Consequently, we will not be able to obtain any such patents to prevent others from using our technology for, and developing and marketing competing products to treat,
these indications. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection.

The patent position of biotechnology and pharmaceutical companies generally Is highly uncertain, involves complex legal and factual questions and has, in recent years, been
the subject of much litigation. As a result, the issuance, scope, validity, enforceability, and commercial value of our and our licensors’ patent rights are highly uncertain. Our
pending  and  future  patent  applications  may  not  result  in  patents  being  issued  which  protect  our  technology  or  product  candidates  or  which  effectively  prevent  others  from
commercializing  competitive  technologies  and  product  candidates.  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. 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 and our licensors’ patent protection.

We may not be aware of all third-party intellectual property rights potentially relating to our product candidates. Publications of discoveries in the scientific literature often lag
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 that we were the first to make the inventions claimed in any owned or any licensed patents or pending patent applications, or that we 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  it  is  not  practical  to
review and know the full scope of all issued and pending patent applications. As a result, the issuance, scope, validity, enforceability, and commercial value of our and our
licensed patent rights are uncertain.

Even  if  the  patent  applications  we  license  or  may  own  in  the  future  do  issue  as  patents,  they  may  not  issue  in  a  form  that  will  provide  us  with  any  meaningful  protection,
prevent competitors or other third parties from competing with us or otherwise provide us with any competitive advantage. Our competitors or other third parties may be able to
circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner.

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

Our intellectual property licenses with third parties may be subject to disagreements over contract interpretation, which could narrow the scope of our rights to the relevant
intellectual property or technology or increase our financial or other obligations to our licensors.

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 harm our
business, financial condition, results of operations and prospects.

We may not be successful in obtaining necessary rights to our product candidates through acquisitions and in-licenses.

We currently have rights to certain intellectual property, through licenses from third parties, to develop our product candidates. Because our programs may require the use of
proprietary rights held by third parties, the growth of our business likely will depend, in part, on our ability to acquire, in-license or use these proprietary rights. We may be
unable to acquire or in-license any compositions, methods of use, processes, or other intellectual property rights from third parties that we identify as necessary for our product
candidates. The licensing or acquisition of third-party intellectual property rights is a competitive area, and several more established companies may pursue strategies to license
or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage over us due to their size,
capital resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or
license  rights  to  us. We  also  may  be  unable  to  license  or  acquire  third-party  intellectual  property  rights  on  terms  that  would  allow  us  to  make  an  appropriate  return  on  our
investment.

45

 
 
 
 
 
 
 
 
 
 
 
We  sometimes  collaborate  with  non-profit  and  academic  institutions  to  accelerate  our  preclinical  research  or  development  under  written  agreements  with  these  institutions.
Typically, these institutions provide us with an option to negotiate a license to any of the institution’s rights in technology resulting from the collaboration. Regardless of such
option, we may be unable to negotiate a license within the specified timeframe or under terms that are acceptable to us. If we are unable to do so, the institution may offer the
intellectual property rights to other parties, potentially blocking our ability to develop our program.

If we are unable to successfully obtain rights to required third-party intellectual property rights or maintain the existing intellectual property rights we have, we may be required
to  expend  significant  time  and  resources  to  redesign  our  product  candidates  or  the  methods  for  manufacturing  them  or  to  develop  or  license  replacement  technology,  all  of
which may not be feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop or commercialize the affected product candidates, which
could harm our business significantly.

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

Periodic  maintenance  fees,  renewal  fees,  annuity  fees  and  various  other  government  fees  on  patents  and/or  applications  will  be  due  to  be  paid  to  the  USPTO  and  various
government  patent  agencies  outside  of  the  United  States  over  the  lifetime  of  our  licensed  patents  and/or  applications  and  any  patent  rights  we  may  own  in  the  future.  We
generally rely on our outside counsel or our licensing partners to pay these fees due to non-U.S. patent agencies. The USPTO and various non-U.S. government patent agencies
require compliance with several procedural, documentary, fee payment and other similar provisions during the patent application process. We employ reputable law firms and
other professionals to help us comply and we are also dependent on our licensors to take the necessary action to comply with these requirements with respect to our licensed
intellectual property. In many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. There are situations,
however, in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant
jurisdiction. In such an event, potential competitors might be able to enter the market and this circumstance could harm our business.

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

Filing, prosecuting, and defending patents on product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in
some countries outside the United States could be less extensive than in the United States. In addition, the laws of some foreign countries do not protect intellectual property
rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from 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,  but  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 proprietary rights
generally.  For  example,  an April  2014  report  from  the  Office  of  the  United  States Trade  Representative  identified  a  number  of  countries,  including  India  and  China,  where
challenges to the procurement and enforcement of patent rights have been reported. Several countries, including India and China, have been listed in the report every year since
1989. Proceedings to enforce our patent 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  and  our  patent  applications  at  risk  of  not  issuing  and  could  provoke  third  parties  to  assert  claims
against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our
efforts  to  enforce  our  intellectual  property  rights  around  the  world  may  be  inadequate  to  obtain  a  significant  commercial  advantage  from  the  intellectual  property  that  we
develop or license.

46

 
 
 
 
 
 
 
 
 
Issued patents covering our product candidates could be found invalid or unenforceable if challenged in court. We may not be able to protect our trade secrets in court.

If  we  or  one  of  our  licensing  partners  initiate  legal  proceedings  against  a  third  party  to  enforce  a  patent  covering  one  of  our  product  candidates,  the  defendant  could
counterclaim that the patent covering our product candidate is invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity or
unenforceability  are  commonplace.  Grounds  for  a  validity  challenge  could  be  an  alleged  failure  to  meet  any  of  several  statutory  requirements,  including  lack  of  novelty,
obviousness, lack of written description or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the
patent withheld information material to patentability from the USPTO, or made a misleading statement, during prosecution. Third parties also may raise similar claims before
administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms include re-examination, post grant review, inter partes review and
equivalent proceedings in foreign jurisdictions. Such proceedings could result in the revocation or cancellation of or amendment to our patents in such a way that they no longer
cover our product candidates. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we
cannot be certain that there is no invalidating prior art, of which the patent examiner and we or our licensing partners were unaware during prosecution. If a defendant were to
prevail on a legal assertion of invalidity or unenforceability, we could lose at least part, and perhaps all, of the patent protection on one or more of our product candidates. Such
a loss of patent protection could harm our business.

In addition to the protection afforded by patents, we rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is not patentable or that
we elect not to patent, processes for which patents are difficult to enforce and any other elements of our product candidate discovery and development processes that involve
proprietary know-how, information or technology that is not covered by patents. However, trade secrets can be difficult to protect. Some courts inside and outside the United
States are less willing or unwilling to protect trade secrets. We seek to protect our proprietary technology and processes, in part, by entering into confidentiality agreements with
our employees, consultants, scientific advisors, collaborators, contractors, and other third-parties. We cannot guarantee that we have entered into such agreements with each
party that may have or have had access to our trade secrets or proprietary technology and processes. We also seek to preserve the integrity and confidentiality of our data and
trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems. While we have confidence in these
individuals, organizations and systems, agreements or security measures may be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets
may otherwise become known or be independently discovered by competitors.

Third-parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could harm our
business.

Our commercial success depends upon our ability and the ability of our collaborators to develop, manufacture, market and sell our product candidates and use our proprietary
technologies without infringing the proprietary rights and intellectual property of third parties. The biotechnology and pharmaceutical industries are characterized by extensive
and complex litigation regarding patents and other intellectual property rights. We may become party to, or threatened with, infringement litigation claims regarding our product
candidates 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, or be threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect
to  our  product  candidates  and  technology,  including  interference  or  derivation  proceedings,  post  grant  review  and  inter  partes  review  before  the  USPTO  or  foreign  patent
offices. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future, regardless of their merit. There is a risk
that third parties may choose to engage in litigation with us to enforce or to otherwise assert their patent rights against us. Even if we believe such claims are without merit, a
court of competent jurisdiction could hold that these third-party patents are valid, enforceable, and infringed, which could adversely affect our ability to commercialize our
product candidates or any other of our product candidates or technologies covered by the asserted third-party patents. In order to successfully challenge the validity of any such
U.S. patent in federal court, we would need to overcome a statutory presumption of validity. As this burden is a high one requiring us to prove by clear and convincing evidence
the invalidity of any such U.S. patent claim, there is no assurance that a court of competent jurisdiction would invalidate the claims of any such U.S. patent. Similar challenges
exist in other jurisdictions. If we are found to infringe a third-party’s valid and enforceable intellectual property rights, we could be required to obtain a license from such third-
party  to  continue  developing,  manufacturing,  and  marketing  our  product  candidates  and  technology.  However,  we  may  not  be  able  to  obtain  any  required  license  on
commercially reasonable terms, or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access to the
same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. We could be forced, including by court order, to cease developing,
manufacturing, and commercializing the infringing technology or product candidates. In addition, we could be found liable for monetary damages, including treble damages
and attorneys’ fees, if we are found to have willfully infringed a patent or other intellectual property right. A finding of infringement could prevent us from manufacturing and
commercializing our product candidates or force us to cease some of our business operations, which could 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  the  confidential
information or trade secrets of third parties could have a similar negative impact on our business, reputation, financial condition, results of operations and prospects.

47

 
 
 
 
 
 
 
Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities.

Competitors  may  infringe  our  intellectual  property  rights  or  the  intellectual  property  rights  of  our  licensing  partners,  or  we  may  be  required  to  defend  against  claims  of
infringement. To counter infringement or unauthorized use claims or to defend against claims of infringement can be expensive and time consuming. 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  more  mature  and  developed  intellectual  property  portfolios.
Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could adversely affect our ability to compete in the marketplace.

We  may  be  subject  to  claims  asserting  that  our  employees,  consultants,  or  advisors  have  wrongfully  used  or  disclosed  alleged  trade  secrets  of  their  current  or  former
employers or claims asserting ownership of what we regard as our own intellectual property.

Many of our employees, consultants or advisors are currently, or were previously, employed at universities or other biotechnology or pharmaceutical companies, including our
competitors or potential competitors. Although we try to ensure that our employees, consultants, and advisors do not use the proprietary information or know-how of others in
their work for us, we may be subject to claims that these individuals or we have used or disclosed intellectual property, including trade secrets or other proprietary information,
of any such individual’s current or former employer. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying
monetary  damages,  we  may  lose  valuable  intellectual  property  rights  or  personnel.  Even  if  we  are  successful  in  defending  against  such  claims,  litigation  could  result  in
substantial costs and be a distraction to management.

In  addition,  while  it  is  our  policy  to  require  our  employees  and  contractors  who  may  be  involved  in  the  conception  or  development  of  intellectual  property  to  execute
agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual
property that we regard as our own. The assignment of intellectual property rights may not be self-executing or the assignment agreements may be breached, and we may be
forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property.

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are
successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to management.

48

 
 
 
 
 
 
 
 
Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

Our success depends heavily on intellectual property, especially on patents. Obtaining and enforcing patents in the gene therapy industry involves both technological and legal
complexity. Therefore, obtaining and enforcing patents is costly, time-consuming, and inherently uncertain.

As of 2013, the United States transitioned to a “first-to-file” system for deciding which party should be granted a patent when two or more patent applications claiming the
same invention are filed by different parties. A third party that files a patent application in the USPTO before us could therefore be awarded a patent covering an invention of
ours even if we made the invention before it was made by the third party. The change to “first-to-file” from “first-to-invent” is one of the changes to the patent laws of the U.S.
resulting from the Leahy-Smith America Invents Act (the “AIA”). Among some of the other significant changes to the patent laws are changes that limit where a patentee may
file  a  patent  infringement  suit  and  provide  opportunities  for  third  parties  to  challenge  any  issued  patent  in  the  USPTO  via  procedures  including  post-grant  and  inter  partes
review. These adversarial actions at the USPTO review patent claims without the presumption of validity afforded to U.S. patents in lawsuits in U.S. federal courts and use a
lower burden of proof than that used in litigation in U.S. federal courts. Therefore, it is generally considered easier for a competitor or third party to have a patent invalidated in
a USPTO post-grant review or inter partes review proceeding than in a litigation in a U.S. federal court. If any of our patents are challenged by a third party in such a USPTO
proceeding, there is no guarantee that we or our licensors or collaborators will be successful in defending the patent, which would result in a loss of the challenged patent right.
The AIA and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of any issued
patents, all of which could harm our business and financial condition.

We also may be subject to a third-party pre-issuance 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 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  products  and
compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. In addition, if
the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or
commercialize current or future products.

If we do not obtain patent term extension and data exclusivity for our product candidates, our business may be harmed.

Depending upon the timing, duration and specifics of any FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible for limited patent
term extension (“PTE”) under the Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch-Waxman Amendments”). The Hatch-Waxman Amendments
permit a PTE of up to five years as compensation for patent term lost during the FDA regulatory review process. PTE cannot extend the remaining term of a patent beyond a
total of 14 years from the date of product approval, only one patent may be extended per FDA-approved product, and only those claims covering the approved drug, a method
for using it or a method for manufacturing it may be extended. Further, certain of our licenses currently or in the future may not provide us with the right to control decisions of
the licensor or its other licensees with respect to PTE under the Hatch-Waxman Act. Thus, if one of our important licensed patents is eligible for PTE, and it covers a product of
another licensee in addition to our own product candidate, we may not be able to obtain that extension if the other licensee seeks and obtains that extension first. Moreover, we
may  not  be  granted  an  extension  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, or the applicable time-period or the scope of
patent protection afforded during any such extension could be less than we request. If we are unable to obtain PTE or the duration 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, and our revenue could be materially reduced.

49

 
 
 
 
 
 
 
 
Intellectual property rights do not necessarily address all potential threats.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and such rights may not adequately
protect our business or permit us to maintain our competitive advantage. For example:

● others may be able to make gene therapy products that are similar to our product candidates but that are not covered by the claims of the patents that we license or may

own in the future;

● we,  or  our  license  partners  or  current  or  future  collaborators,  might  not  have  been  the  first  to  make  the  inventions  covered  by  the  issued  patent  or  pending  patent

application that we license or may own in the future;

● we, or our license partners or current or future collaborators, might not have been the first to file patent applications covering certain of our or their inventions;
● others  may  independently  develop  similar  or  alternative  technologies  or  duplicate  any  of  our  technologies  without  infringing  our  owned  or  licensed  intellectual

property rights;

● it is possible that our pending patent applications or those that we may own in the future will not lead to issued patents;
● issued patents that we hold rights to may be held invalid or unenforceable, including as a result of legal challenges by our competitors;
● our competitors might conduct research and development activities in countries where we do not have patent rights and then use the information learned from such

activities to develop competitive products for sale in our major commercial markets;

● we may not develop additional proprietary technologies that are patentable;
● the patents of others may have an adverse effect on our business; and
● we  may  choose  not  to  file  a  patent  application  for  certain  trade  secrets  or  know-how,  and  a  third  party  may  subsequently  file  a  patent  application  covering  such

intellectual property.

Should any of these events occur, they could significantly harm our business, financial condition, results of operations and prospects.

Risks related to our financial condition and capital requirements

We have experienced a history of losses; we expect to incur future losses and we may be unable to obtain necessary additional capital to fund operations in the future.

We have recorded minimal revenue to date and have incurred an accumulated deficit of approximately $695.3 million through December 31, 2022. The net loss for the year
ended  December  31,  2022,  was  $39.7  million,  including  impairment  charges  of  $5.6  million.  Our  losses  have  resulted  principally  from  costs  incurred  in  research  and
development activities related to our efforts to develop clinical drug candidates and from the associated administrative costs.

We  require  substantial  capital  for  our  development  programs  and  operating  expenses,  to  pursue  regulatory  clearances  and  to  prosecute  and  defend  our  intellectual  property
rights. We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. We anticipate that our expenses will increase substantially
if and as we:

● seek regulatory and marketing approvals for our product candidates that successfully complete clinical studies;
● continue our research and preclinical and clinical development of our product candidates;
● further develop the manufacturing process for our vectors or our product candidates;
● expand the scope of our current clinical studies for our product candidates;
● change or add additional manufacturers or suppliers;
● seek to identify and validate additional product candidates;
● acquire or in-license other product candidates and technologies;
● make milestone or other payments under any license agreements;
● maintain, protect and expand our intellectual property portfolio;

50

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● establish  a  sales,  marketing  and  distribution  infrastructure  in  the  United  States  and  Europe  to  commercialize  any  products  for  which  we  may  obtain  marketing

approval;

● attract and retain skilled personnel;
● build  additional  infrastructure  to  support  our  operations  as  a  larger  public  company  and  our  product  development  and  planned  future  commercialization  efforts,

including manufacturing capacity; and

● experience any delays or encounter issues with any of the above.

The net losses we incur may fluctuate significantly from quarter to quarter and year to year, such that a period-to-period comparison of our results of operations may not be a
good indication of our future performance. In any particular quarter or quarters, our operating results could be below the expectations of securities analysts or investors, which
could cause our stock price to decline.

As of December 31, 2022, our cash, cash equivalents, restricted cash and short-term investments were $52.5 million. Following a comprehensive portfolio review in early 2022,
we have decided to focus our research and development resources on the EB-101 program with the objective of reducing operating expenses and extending our cash runway. As
part of this portfolio prioritization, we have intensified our pursuit of a strategic partnership to take over development activities for our AAV-based gene therapy ABO-102 for
MPS  IIIA  and  we  have  discontinued  development  of  our AAV-based  gene  therapy ABO-101  for  MPS  IIIB.  Based  upon  these  current  operating  plans,  our  ability  to  access
additional financial resources and/or our financial flexibility to further reduce operating expenses if required, we believe that we have sufficient resources to fund operations
through at least the next 12 months from the date of the issuance of our consolidated financial statements. However, our operating plan may change as a result of many factors
currently unknown to us, and we may need to seek additional funds sooner than planned, through public or private equity, government or other third-party funding, marketing
and  distribution  arrangements  and  other  collaborations,  strategic  alliances  and  licensing  arrangements  or  a  combination  of  these  approaches.  In  any  event,  we  will  require
additional  capital  to  obtain  potential  regulatory  approval  for,  and  to  potentially  commercialize,  our  product  candidates.  Even  if  we  believe  we  have  sufficient  funds  for  our
current or future operating plans, we may seek additional capital if market conditions are favorable or if we have specific strategic objectives.

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. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of
any financing may adversely affect the holdings or the rights of our stockholders and the issuance of additional securities, whether common stock, preferred stock or debt, by
us,  or  the  possibility  of  such  issuance,  may  cause  the  market  price  of  our  shares  to  decline.  The  sale  of  additional  equity  or  convertible  securities  would  dilute  all  of  our
stockholders. The incurrence of indebtedness would result in increased fixed payment obligations, and we may be required to agree to certain restrictive covenants, such as
limitations  on  our  ability  to  incur  additional  debt,  limitations  on  our  ability  to  acquire,  sell  or  license  intellectual  property  rights  and  other  operating  restrictions  that  could
adversely impact our ability to conduct our business. We could also be required to seek funds through arrangements with collaborative partners or otherwise at an earlier stage
than otherwise would be desirable and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us,
any of which may have a material adverse effect on our business, operating results, and prospects.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay, or discontinue one or more of our research or development programs or
the commercialization of any product candidates or be unable to expand our operations or otherwise capitalize on our business opportunities, as desired, which could materially
affect our business, financial condition, and results of operations.

We do not have significant operating revenue and may never achieve profitability.

To date, we have funded our operations primarily through public offerings of our common stock. Our ability to achieve significant revenue or profitability depends upon our
ability to complete the development of our drug candidates, to develop and obtain patent protection and regulatory approvals for our drug candidates and to manufacture and
commercialize the resulting drugs. We are not expecting any significant revenues in the short-term from our products or product candidates. Furthermore, we may not be able to
ever  successfully  identify,  develop,  commercialize,  patent,  manufacture,  obtain  required  regulatory  approvals  or  market  any  products.  Moreover,  even  if  we  do  identify,
develop,  commercialize,  patent,  manufacture,  or  obtain  required  regulatory  approvals  to  market  additional  products,  we  may  not  generate  revenues  or  royalties  from
commercial  sales  of  these  products  for  a  significant  number  of  years,  if  at  all. Therefore,  our  operations  are  subject  to  all  the  risks  inherent  in  the  establishment  of  a  new
business  enterprise.  In  the  next  couple  of  years,  we  expect  limited  revenues  from  product  sales,  if  any,  and  any  amounts  that  we  receive  under  strategic  partnerships  and
research or drug development collaborations that we may establish and, as a result, we may be unable to achieve or maintain profitability in the future or to achieve significant
revenues in order to fund our operations.

51

 
 
 
 
 
 
 
 
 
 
 
 
 
Failure to achieve and maintain effective internal controls could have a material adverse effect on our business.

Effective internal controls are necessary for us to provide reliable financial reports. If we cannot provide reliable financial reports, our operating results could be harmed. All
internal  control  systems,  no  matter  how  well  designed,  have  inherent  limitations.  Therefore,  even  those  systems  determined  to  be  effective  can  provide  only  reasonable
assurance with respect to financial statement preparation and presentation.

Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm our operating results, or cause us to fail to meet
our  reporting  obligations.  Failure  to  achieve  and  maintain  an  effective  internal  control  environment  could  cause  investors  to  lose  confidence  in  our  reported  financial
information, which could have a material adverse effect on our stock price. Failure to comply with Section 404 of the Sarbanes-Oxley Act could also potentially subject us to
actions or investigations by the SEC or other regulatory authorities.

We expect to continue to need to raise additional capital to operate our business, and our failure to obtain funding when needed or on terms that are favorable to us may
force us to delay, reduce or eliminate our development programs or commercialization efforts.

We will need to raise additional capital to fund our future operations and we cannot be certain that funding will be available to us on acceptable terms on a timely basis, or at
all. We expect to continue to spend substantial amounts on regulatory approval efforts, product development (including commercialization activities), and conducting potential
future pre-clinical or clinical trials for our product candidates. Our ability to raise capital through the sale of securities may be limited by our number of authorized shares of
common stock and various rules of the SEC and the Nasdaq that place limits on the number and dollar amount of securities that we may sell. If we fail to raise additional funds
on acceptable terms or at all, we may be unable to complete planned preclinical and clinical trials, obtain approval of our product candidates from the FDA and other regulatory
authorities,  or  successfully  commercialize  any  of  our  product  candidates.  In  addition,  we  could  be  forced  to  delay,  discontinue,  or  curtail  product  development,  or  forego
licensing in attractive business opportunities. Any additional sources of financing will likely involve the issuance of our equity or debt securities, which will have a dilutive
effect on our stockholders.

Risks related to our common stock

The market price of our common stock may be volatile and adversely affected by several factors.

The market price of our common stock could fluctuate significantly in response to various factors and events, including:

● our ability to integrate operations, technology, products, and services;
● our ability to execute our business plan;
● operating results below expectations;
● announcements concerning product development results, including clinical trial results;
● regulatory or legal developments in the U.S. or EU, including decisions from regulatory agencies relating to our product candidates;
● litigation or public concern about the safety of our potential products;
● our issuance of additional securities, including debt or equity or a combination thereof, which will be necessary to fund our operating expenses;
● announcements of technological innovations or new products by us or our competitors;
● loss of any strategic relationship;
● industry developments, including, without limitation, changes in healthcare policies or practices or third-party reimbursement policies;
● economic and other external factors;
● period-to-period fluctuations in our financial results; and
● whether an active trading market in our common stock develops and is maintained.

52

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition, the securities markets have from time-to-time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular
companies. These market fluctuations may also materially and adversely affect the market price of our common stock.

Raising  additional  funds  by  issuing  securities  or  through  licensing  or  lending  arrangements  or  through  our  at-the-market  sale  agreement  may  cause  dilution  to  our
existing stockholders, restrict our operations, or require us to relinquish proprietary rights.

If we raise additional capital by issuing equity securities, the share ownership of existing stockholders will be diluted. Any future debt financing may involve covenants that,
among other restrictions, limit our ability to incur liens or additional debt, pay dividends, redeem, or repurchase our common stock, make certain investments or engage in
certain merger, consolidation, or asset sale transactions. In addition, if we raise additional funds through licensing arrangements or the disposition of any of our assets, it may be
necessary to relinquish potentially valuable rights to our product candidates or grant licenses on terms that are not favorable to us.

The terms of any financing may adversely affect the holdings or the rights of our stockholders and the issuance of additional securities, whether equity or debt, or the possibility
of such issuance, may cause the market price of our shares to decline. We may sell shares or other securities in other offerings, including under our open market sale agreement,
at a price per share that is less than the prices per share paid by other investors, and investors purchasing shares of our common stock, preferred stock or other securities in the
future could have rights superior to existing stockholders. The sale of additional equity or convertible securities would dilute all of our stockholders and the terms of these
securities may include liquidation or other preferences that adversely affect our existing stockholders.

We have not paid cash dividends in the past and do not expect to pay cash dividends in the foreseeable future. Any return on investment may be limited to the value of our
common stock.

We have never paid cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future. The payment of dividends
on our capital stock will depend on our earnings, financial condition and other business and economic factors affecting us at such time as the board of directors may consider
relevant. If we do not pay dividends, our common stock may be less valuable because a return on stockholder investment will only occur if the common stock price appreciates.

Our quarterly operating results may fluctuate significantly.

We expect our operating results to be subject to quarterly fluctuations. Our net loss and other operating results will be affected by numerous factors, including:

● variations in the level of expenses related to our development programs;
● addition or termination of clinical trials;
● any intellectual property infringement lawsuit or arbitration in which we are, or may become, involved;
● regulatory developments affecting our product candidates; and
● our execution of any collaborative, licensing or similar arrangements, and the timing of payments we may make or receive under these arrangements.

If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially. Furthermore, any
quarterly fluctuations in our operating results may, in turn, cause the price of our common stock to fluctuate substantially.

Provisions of our charter documents could discourage an acquisition of our company that would benefit our stockholders and may have the effect of entrenching, and
making it difficult to remove, management.

Provisions of our Certificate of Incorporation and Bylaws may make it more difficult for a third party to acquire control of us, even if a change in control would benefit our
stockholders. In particular, shares of our preferred stock may be issued in the future without further stockholder approval and upon such terms and conditions, and having such
rights, privileges and preferences, as our Board of Directors may determine, including, for example, rights to convert into our common stock. The rights of the holders of our
common stock will be subject to, and may be adversely affected by, the rights of the holders of any of our preferred stock that may be issued in the future. The issuance of our
preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for
a third party to acquire control of us. This could limit the price that certain investors might be willing to pay in the future for shares of our common stock and discourage these
investors from acquiring a majority of our common stock. Further, the existence of these corporate governance provisions could have the effect of entrenching management and
making it more difficult to change our management.

53

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our ability to use our net operating loss carry forwards may be subject to limitation.

Generally, a change of more than 50% in the ownership of a company’s stock, by value, over a three-year period constitutes an ownership change for U.S. federal income tax
purposes. An ownership change may limit our ability to use our net operating loss carryforwards attributable to the period prior to the change. As a result, if we earn net taxable
income, our ability to use our pre-change net operating loss carryforwards to offset U.S. federal taxable income may become subject to limitations, which could potentially
result in increased future tax liability for us. As of December 31, 2022, we had net operating loss carryforwards aggregating approximately $359.0 million.

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

The following discussion should be read in conjunction with our consolidated financial statements and related notes included in this Form 10-K.

Abeona is a clinical-stage biopharmaceutical company developing cell and gene therapies for life-threatening diseases. Our lead clinical program is EB-101, an autologous,
engineered cell therapy currently in development for recessive dystrophic epidermolysis bullosa (“RDEB”). In November 2022, we announced positive topline data from the
VIITAL™  study  evaluating  the  efficacy,  safety  and  tolerability  of  EB-101.  The  VIITAL™  study  met  its  two  co-primary  efficacy  endpoints  demonstrating  statistically
significant, clinically meaningful improvements in wound healing and pain reduction in large chronic RDEB wounds. Based on the positive topline results, we intend to submit
a Biologics License Application (“BLA”) for EB-101 to the U.S. Food and Drug Administration (“FDA”) in late second quarter of 2023 or early third quarter of 2023.

Our development portfolio also features adeno-associated virus (“AAV”) based gene therapies designed to treat ophthalmic diseases using the novel AIM™ capsid platform that
we have exclusively licensed from the University of North Carolina at Chapel Hill, and internal AAV vector research programs.

We have continued to prepare our current Good Manufacturing Practices (“cGMP”) commercial facility in Cleveland, Ohio for manufacturing EB-101 drug product to support
our planned BLA filing to the FDA. EB-101 study drug product for all our VIITAL™ study participants has been manufactured at our Cleveland facility.

Preclinical Pipeline

Our preclinical programs are investigating the use of novel AAV capsids in AAV-based therapies for serious eye diseases, including ABO-504 for Stargardt disease, ABO-503
for X-linked retinoschisis (XLRS) and ABO-505 for autosomal dominant optic atrophy (ADOA). In 2022, we evaluated the ability of our gene constructs and capsids to deliver
and express the recombinant protein in target eye tissues and rescue mutant phenotypes in mouse disease models. The Company has submitted a pre-Investigational New Drug
(IND) application meeting request for XLRS to the FDA to gain alignment on IND enabling toxicity studies and clinical trial design. The Company expects to present new
preclinical data from these programs at a future medical meeting in second quarter of 2023.

License and other revenues for the year ended December 31, 2022 was $1.4 million, as compared to $3.0 million for the same period of 2021. The revenue in 2022 resulted
from a clinical milestone achieved in the second quarter of 2022 under a sublicense agreement we entered into with Taysha Gene Therapies (“Taysha”) in October 2020 relating
to an investigational AAV-based gene therapy for Rett syndrome, including certain intellectual property relating to MECP2 gene constructs and regulation of their expression.
There was also revenue consisting of the recognition of deferred revenue related to grants for the ABO-102 and ABO-101 development programs and revenue related to the
sublet of a portion of our existing leases.

The revenue in 2021 resulted from a clinical milestone achieved in December 2021 under a sublicense agreement we entered into with Taysha in August 2020 for ABO-202, an
AAV gene therapy for CLN1 disease (also known as infantile Batten disease).

Royalties

Total royalties expenses were $0.4 million for the year ended December 31, 2022, as compared to nil for the same period of 2021, an increase of $0.4 million. The increase in
expense was due to royalties owed to our licensors resulting from the $1.0 million milestone due from Taysha.

Research and development

Research  and  development  expenses  include,  but  are  not  limited  to,  payroll  and  personnel  expense,  lab  supplies,  preclinical  and  development  costs,  clinical  trial  costs,
manufacturing and manufacturing facility costs, costs associated with regulatory approvals, depreciation on lab supplies and manufacturing facilities, and consultant-related
expenses.

Total research and development spending for the year ended December 31, 2022 was $28.9 million, as compared to $38.7 million for the same period of 2021, a decrease of
$9.8 million. The decrease in expenses was primarily due to:

● decreased clinical and development work for our cell and gene therapy product candidates and other related costs of $5.7 million which primarily relates to the license

out/discontinuation of our MPSIII programs;

● decreased non-cash stock compensation expenses of $3.2 million; and
● decreased salary and related costs of $1.0 million; partially offset by
● increased other costs of $0.1 million.

We  expect  our  research  and  development  activities  to  continue  as  we  attempt  to  advance  our  product  candidates  towards  potential  regulatory  approval,  reflecting  costs
associated with:

● employee and consultant-related expenses;
● preclinical and developmental costs;
● clinical trial costs;
● the cost of acquiring and manufacturing clinical trial materials; and
● costs associated with regulatory approvals.

General and administrative

General and administrative expenses primarily consist of payroll and personnel costs, office facility costs, public reporting company related costs, professional fees (e.g., legal
expenses) and other general operating expenses not otherwise included in research and development expenses.

Total general and administrative expenses were $17.2 million for the year ended December 31, 2022, as compared to $21.6 million for the same period of 2021, a decrease of
$4.4 million. The decrease in expenses was primarily due to:

● decreased professional fees of $3.9 million;
● decreased non-cash stock-based compensation of $2.7 million; partially offset by
● increased other costs of $0.8 million; and
● increased salary and related costs of $1.4 million.

Impairment of goodwill

Goodwill impairment charge was nil for the year ended December 31, 2022, as compared to $32.5 million in the same period of 2021. As of year-end 2021, the carrying value
of our net assets was determined to exceed the fair value of our net assets, and therefore, we recorded a goodwill impairment charge of $32.5 million.

Impairment of licensed technology

Impairment of licensed technology was $1.4 million for the year ended December 31, 2022, as compared to nil in the same period of 2021. The licensed technology was for the
ABO-102  and ABO-101  development  programs,  which,  as  a  result  of  our  shift  in  priorities,  we  determined  the  licensed  technology  had  no  future  value  and  thus  recorded
impairment of $1.4 million for the year ended December 31, 2022.

Impairment of right-of-use lease assets

Impairment of right-of-use lease assets was $2.5 million for the year ended December 31, 2022, as compared to nil in the same period of 2021. A portion of the impairment was
related  to  a  lease  for  a  future  manufacturing  facility  for  the ABO-102  and ABO-101  development  programs,  which,  as  a  result  of  our  shift  in  priorities,  we  determined  the
portion of this lease had no future value and thus recorded impairment of $1.6 million for the for the year ended December 31, 2022. In addition, we sublet a portion of our
leased properties which indicated that a portion of the lease had a reduced future value and thus recorded impairment of $0.9 million for the year ended December 31, 2022.

Impairment of construction-in-progress

Impairment of construction-in-progress was $1.8 million for the year ended December 31, 2022, as compared to nil in the same period of 2021. The construction-in-progress
was for a facility for the ABO-102 and ABO-101 development programs. As a result of our shift in priorities, we determined the construction-in-progress facility had no future
value and thus recorded impairment of $1.8 million for the for the year ended December 31, 2022, which was net of a cash refund from the builder of approximately $1.5
million.

Gain on settlement with licensor

Gain on settlement with licensor was nil for the year ended December 31, 2022, as compared to $6.7 million in the same period of 2021. On November 12, 2021, we entered
into  a  settlement  agreement  with  REGENXBIO,  Inc.  (“REGENXBIO”)  to  resolve  all  current  disputes  between  us  and  REGENXBIO.  The  accounting  for  this  settlement
agreement resulted in a $6.7 million gain on settlement with REGENXBIO in the year ended December 31, 2021.

PPP loan payable forgiveness income

PPP loan payable forgiveness income was nil for the year ended December 31, 2022, as compared to $1.8 million in the same period of 2021. In July 2021, we received notice
from the SBA that our PPP loan had been forgiven so the PPP loan payable was reversed in the year ended December 31, 2021.

Interest income

Interest income was $0.4 million for the year ended December 31, 2022, as compared to $40,000 in the same period of 2021. The increase resulted from higher earnings on
short-term investments driven by higher interest rates and a higher average balance of short-term investments.

Interest expense

Interest expense was $0.7 million for the year ended December 31, 2022, as compared to $3.7 million in the same period of 2021. The decrease results primarily from the
resolution of a disputed liability owed to our prior licensor, REGENXBIO.

Change in fair value of warrant liabilities

The change in fair value of warrant liabilities was $11.4 million for the year ended December 31, 2022, as compared to nil in the same period of 2021. We issued stock purchase
warrants that are required to be classified as a liability and valued at fair market value at each reporting period. The change in the fair value of warrant liabilities resulted in a
gain of $11.4 million due primarily to the reduction in our stock price year over the year and a shorter term.

Other income

Other income was $0.1 million for the year ended December 31, 2022, as compared to $15,000 in the same period of 2021. The increase was primarily a result of a gain on
lease termination of $0.3 million partially offset by $0.1 million of losses on the disposal of fixed assets.

Investing activities

Net cash used in investing activities was $24.0 million for the year ended December 31, 2022, primarily comprised of purchases of short-term investments of $78.2 million and
capital expenditures of $0.1 million, partially offset by proceeds from maturities of short-term investments of $52.6 million and proceeds from the disposal of property and
equipment of $1.7 million.

Net cash provided by investing activities was $66.1 million for the year ended December 31, 2021, primarily comprised of proceeds from maturities of short-term investments
of $90.4 million, partially offset by purchases of short-term investments of $20.2 million and capital expenditures of $4.1 million.

Financing activities

Net cash provided by financing activities was $43.2 million for the year ended December 31, 2022, primarily comprised of proceeds of $12.8 million from open market sales of
common stock pursuant to the ATM Agreement (as defined below) and proceeds of $34.1 million from a private offering of common stock and warrants on November 3, 2022,
partially offset by the proceeds and redemption of our convertible redeemable preferred stock.

Net cash provided by financing activities was $24.9 million for the year ended December 31, 2021, primarily comprised of proceeds of $17.4 million from the issuance of
common stock and warrants in a public offering, proceeds of $8.0 million from open market sales of common stock pursuant to the ATM Agreement and proceeds of $0.8
million from the exercise of stock options, partially offset by the payment of offering costs in a public offering of $1.5 million.

We have historically funded our operations primarily through sales of common stock.

Our principal source of liquidity is cash, cash equivalents, restricted cash and short-term investments, collectively referred to as our cash resources. As of December 31, 2022,
our  cash  resources  were  $52.5  million.  We  believe  that  our  current  cash  and  cash  equivalents,  restricted  cash  and  short-term  investments  are  sufficient  resources  to  fund
operations through at least the next 12 months from the date of this report on Form 10-K. We may need to secure additional funding to carry out all of our planned research and
development activities. If we are unable to obtain additional financing or generate license or product revenue, the lack of liquidity and sufficient capital resources could have a
material adverse effect on our future prospects.

We have an open market sale agreement with Jefferies LLC (as amended, the “ATM Agreement”) pursuant to which, we may sell from time to time, through Jefferies LLC,
shares of our common stock for an aggregate sales price of up to $150.0 million. Any sales of shares pursuant to this agreement are made under our effective “shelf” registration
statement on Form S-3 that is on file with and has been declared effective by the SEC. We are currently subject to General Instruction I.B.6 of Form S-3, as a result of which
the amount of funds we can raise through primary public offerings of securities in any 12-month period using our registration statement on Form S-3 is limited to one-third of
the aggregate market value of the voting and non-voting common equity held by non-affiliates. We remain subject to this one-third limitation until such time our public float
exceeds $75 million. We sold 146,872 shares of our common stock under the ATM Agreement and received $8.1 million of net proceeds during the year ended December 31,
2021. We sold 3,479,016 shares of our common stock under the ATM Agreement and received $12.8 million of net proceeds during the year ended December 31, 2022.

Since our inception, we have incurred negative cash flows from operations and have expended, and expect to continue to expend substantial funds to complete our planned
product development efforts. We have not been profitable since inception and to date have received limited revenues from the sale of products or licenses. We expect to incur
losses for the next several years as we continue to invest in product research and development, preclinical studies, clinical trials, and regulatory compliance and cannot provide
assurance that we will ever be able to generate sufficient product sales or royalty revenue to achieve profitability on a sustained basis, or at all.

If we raise additional funds by selling additional equity securities, the relative equity ownership of our existing investors will be diluted, and the new investors could obtain
terms more favorable than previous investors. If we raise additional funds through collaborations, strategic alliances, or licensing arrangements with third parties, we may have
to relinquish valuable rights to our technologies, future revenue streams, research programs, or product candidates or grant licenses on terms that may not be favorable to us. If
we are unable to raise additional funds through equity or debt financing when needed, we may be required to delay, limit, or terminate our product development programs or
any future commercialization efforts or grant rights to develop and market product candidates to third parties that we would otherwise prefer to develop and market ourselves.

Our future capital requirements and adequacy of available funds depend on many factors, including:

● the successful development, regulatory approval and commercialization of our cell and gene therapy and other product candidates;
● the ability to establish and maintain collaborative arrangements with corporate partners for the research, development, and commercialization of products;
● continued scientific progress in our research and development programs;
● the magnitude, scope and results of preclinical testing and clinical trials;
● the costs involved in filing, prosecuting, and enforcing patent claims;
● the costs involved in conducting clinical trials;
● any continuing impact to our business, operations, and clinical programs from the COVID-19 pandemic and government actions related thereto;
● competing technological developments;
● the cost of manufacturing and scale-up;
● the ability to establish and maintain effective commercialization arrangements and activities; and
● the successful outcome of our regulatory filings.

Due  to  uncertainties  and  certain  of  the  risks  described  above,  our  ability  to  successfully  commercialize  our  product  candidates,  our  ability  to  obtain  applicable  regulatory
approval  to  market  our  product  candidates,  our  ability  to  obtain  necessary  additional  capital  to  fund  operations  in  the  future,  our  ability  to  successfully  manufacture  our
products  and  our  product  candidates  in  clinical  quantities  or  for  commercial  purposes,  government  regulation  to  which  we  are  subject,  the  uncertainty  associated  with
preclinical and clinical testing, intense competition that we face, the potential necessity of licensing technology from third parties and protection of our intellectual property, it
is not possible to reliably predict future spending or time to completion by project or product category or the period in which material net cash inflows from significant projects
are expected to commence. If we are unable to timely complete a particular project, our research and development efforts could be delayed or reduced, our business could suffer
depending on the significance of the project and we might need to raise additional capital to fund operations, as discussed in the risks above.

We plan to continue our policy of investing any available funds in suitable certificates of deposit, money market funds, government securities and investment-grade, interest-
bearing securities. We do not invest in derivative financial instruments.

Contractual Obligations

We  enter  into  agreements  in  the  normal  course  of  business  with  clinical  research  organizations  for  clinical  trials  and  clinical  manufacturing  organizations  for  supply
manufacturing and with vendors for preclinical research studies and other services and products for operating purposes. These contractual obligations are cancelable at any time
by us, generally upon prior written notice to the vendor, and are thus not included in the contractual obligations table.

Operating lease amounts represent future minimum lease payments under our non-cancelable operating lease agreements. The minimum lease payments above do not include
any related common area maintenance charges or real estate taxes.

On November 12, 2021, we entered into a Settlement Agreement with REGENXBIO to resolve all current disputes between the parties including the aforementioned AAA
arbitration and New York State Supreme Court action. In accordance with the Settlement Agreement, we agreed to pay REGENXBIO a total of $30 million, payable as follows:
(1)  $20  million  payable  that  was  paid  in  2021  after  execution  of  the  Settlement Agreement,  (2)  $5  million  on  the  first  anniversary  of  the  effective  date  of  the  Settlement
Agreement, and (3) $5 million upon the earlier of: (i) the third anniversary of the effective date of the Settlement Agreement or (ii) the closing of a Strategic Transaction, as
defined in the Settlement Agreement. As of December 31, 2022, we have recorded the payable to licensor in the contractual obligations as the one remaining payments due to
REGENXBIO under the Settlement Agreement.

In  addition,  we  are  also  party  to  other  license  agreements,  which  include  contingent  payments.  However,  contingent  payments  related  to  these  license  agreements  are  not
disclosed as the satisfaction of these contingent payments is uncertain as of December 31, 2022 and, if satisfied, the timing of payment for these amounts was not reasonably
estimable as of December 31, 2022. Commitments related to the license agreements include contingent payments that will become payable if and when certain development,
regulatory and commercial milestones are achieved. During the next 12 months, we do not expect to make milestone payments related to such license agreements.

Critical Accounting Estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates
and assumptions that affect the reported amounts and related disclosures in the financial statements. Management considers an accounting estimate to be critical if:

● it requires assumptions to be made that were uncertain at the time the estimate was made, and

● changes in the estimate or different estimates that could have been selected could have a material impact in our results of operations or financial condition.

While we base our estimates and judgments on our experience and on various other factors that we believe to be reasonable under the circumstances, actual results could differ
from those estimates and the differences could be material.

Leases

We account for leases pursuant to ASC 842, Leases (“ASC 842”). ASC 842 requires the recognition of lease assets and lease liabilities by lessees for those leases classified as
operating leases. We determine if an arrangement is a lease at inception or when amended. Right-of-use lease assets represent our right to use an underlying asset for the lease
term and lease liabilities represent our obligation to make lease payments arising from the lease. The classification of our leases as operating or finance leases along with the
initial measurement and recognition of the associated right-of-use assets and lease liabilities is performed at the lease commencement date or when amended. The measurement
of lease liabilities is based on the present value of future lease payments over the lease term. As our leases do not provide an implicit rate, we use our incremental borrowing
rate  based  on  the  information  available  at  the  lease  commencement  date  in  determining  the  present  value  of  future  lease  payments.  The  right-of-use  asset  is  based  on  the
measurement of the lease liability and includes any lease payments made prior to or on lease commencement or lease amendment and excludes lease incentives and initial
direct costs incurred, as applicable. Rent expense for our operating leases is recognized on a straight-line basis over the lease term. We do not have any leases classified as
finance leases.

Our leases do not have significant rent escalation, holidays, concessions, material residual value guarantees, material restrictive covenants or contingent rent provisions. Our
leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other maintenance costs), which are
accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases. We have elected the practical
expedient to exclude short-term leases from our right-of-use assets and lease liabilities.

Most leases include one or more options to renew. The exercise of lease renewal options is typically at our sole discretion; therefore, the majority of renewals to extend the
lease terms are not included in our right-of-use assets and lease liabilities as they are not reasonably certain of exercise. We regularly evaluate the renewal options and when
they are reasonably certain of exercise, we include the renewal period in our lease term.

On March 31, 2022, we announced that we were pursuing a strategic partner to take over development activities of ABO-102 and we were discontinuing development of ABO-
101. As a result of this shift in priorities, we determined the portion of the lease that was dedicated to the future facility for the ABO-101 and ABO-102 programs, had no future
value  and  thus,  we  recorded  an  impairment  charge  of  $1.6  million  for  the  year  ended  December  31,  2022.  In  addition,  we  sublet  a  portion  of  our  leased  properties  which
indicated that a portion of the lease had a reduced future value and thus recorded impairment of $0.9 million for the year ended December 31, 2022

Licensed Technology

We maintain licensed technology on our consolidated balance sheet until either the licensed technology agreement underlying it is completed or the asset becomes impaired.
When we determine that an asset has become impaired or we abandon a project, we write down the carrying value of the related intangible asset to its fair value and take an
impairment charge in the period in which the impairment occurs.

Generally, licensed technology is amortized over the life of the patent or the agreement. We test our intangible assets for impairment if indicators are present or changes in
circumstance  suggest  that  impairment  may  exist.  Events  that  could  result  in  an  impairment,  or  trigger  an  interim  impairment  assessment,  include  the  receipt  of  additional
clinical or nonclinical data regarding our drug candidate or a potentially competitive drug candidate, changes in the clinical development program for a drug candidate or new
information regarding potential sales for the drug. In connection with any impairment assessment, we compare the fair value of the asset as of the date of the assessment with
the carrying value of the asset on our consolidated balance sheets.

During 2022, in connection with the license of our ABO-102 asset for the treatment of Sanfilippo syndrome type A (MPS IIIA) to Ultragenyx and the discontinuation of the
ABO-101  program  for  the  treatment  of  Sanfilippo  syndrome  type  B  (MPS  IIIB),  we  recorded  an  impairment  charge  of  $1.4  million  as  we  determined  that  there  was  no
remaining value of the licensed technology.

In 2021, we did not impair any licensed technology.

Impairment of Long-Lived Assets

Long-Lived Assets consist of property and equipment, licensed technology, and right-of-use (“ROU”) assets. We test our long-lived assets for impairment on an annual basis, or
when events and circumstances indicate that the carrying value of an asset or group of assets may not be fully recoverable. If indicators are present or changes in circumstance
suggest that impairment may exist. We assess the recoverability of the affected long-lived assets by determining whether the carrying value of such assets can be recovered
through undiscounted future operating cash flows. If the carrying amount is not recoverable, we measure the amount of any impairment by comparing the carrying value of the
asset to the present value of the expected future cash flows associated with the use of the asset.

Goodwill

In accordance with ASC 350 — Intangibles — Goodwill and Other, we test goodwill for impairment on an annual basis and in the interim if events and circumstances indicate
that  goodwill  may  be  impaired.  The  events  and  circumstances  that  are  considered  include  business  climate  and  market  conditions,  legal  factors,  operating  performance
indicators and competition. Impairment of goodwill is evaluated on a qualitative basis before calculating the fair value of the entity. If the qualitative assessment suggests that
impairment  is  more  likely  than  not,  a  quantitative  impairment  analysis  is  performed.  The  quantitative  analysis  involves  comparison  of  the  fair  value  of  the  entity  with  its
carrying  value.  The  valuation  of  an  entity  requires  judgment.  In  making  these  judgments,  we  evaluate  the  financial  health  of  our  business.  Decreases  in  the  value  of  our
common stock could cause the carrying value of the entity to exceed its fair value. If the carrying amount of the entity exceeds its fair value, an impairment loss is recognized in
an amount equal to that excess, limited to the total amount of goodwill. If an event occurs that would cause a revision to the estimates and assumptions used in analyzing the
value of the goodwill, the revision could result in a noncash impairment charge that could have a material impact on the financial results.

We experienced a steep decline in our share price during the year ended December 31, 2021. We performed our annual goodwill impairment tested as of year-end 2021 and
determined that the carrying value of our net assets exceeded fair value using our market capitalization as a proxy for fair value. In accordance with ASC 350, we recognized an
impairment  loss  for  that  excess  of  carrying  value  over  fair  value  but  limited  to  the  total  amount  of  goodwill  recorded  on  our  consolidated  balance  sheets. As  a  result,  we
recorded a goodwill impairment charge of $32.5 million during the year ended December 31, 2021.

Revenue Recognition

We account for revenue under ASC 606, Revenue from Contracts with Customers, (“ASC 606”). We recognize revenue when our customer obtains control of promised goods or
services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue recognition for arrangements
that we determine are within the scope of ASC 606, we perform the following five steps: (i) identify the contract(s) with our customer; (ii) identify the performance obligations
in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we
satisfy a performance obligation.

Sublicense and Inventory Purchase Agreements Relating to CLN1 Disease: In August 2020, we entered into sublicense and inventory purchase agreements with Taysha Gene
Therapies  (“Taysha”)  relating  to  a  potential  gene  therapy  for  CLN1  disease.  Under  the  sublicense  agreement,  Taysha  received  worldwide  exclusive  rights  to  intellectual
property  and  know-how  relating  to  the  research,  development,  and  manufacture  of  the  potential  gene  therapy,  which  we  had  referred  to  as ABO-202.  Under  the  inventory
purchase agreement, we sold to Taysha certain inventory and other items related to ABO-202. We assessed these contracts at contract inception and determined that, under ASC
606,  the  two  contracts  would  be  combined  and  accounted  for  as  a  single  contract,  with  a  single  performance  obligation. We  assessed  the  nature  of  the  promised  license  to
determine  whether  the  license  has  significant  stand-alone  functionality  and  evaluated  whether  such  functionality  can  be  retained  without  ongoing  activities  by  us  and
determined that the license has significant stand-alone functionality. Furthermore, we have no ongoing activities associated with the license to support or maintain the license’s
utility. Based on this, we determined that the pattern of transfer of control of the license to Taysha was at a point in time.

The transaction price of the contract includes (i) $7.0 million of fixed consideration, (ii) up to $26.0 million of variable consideration in the form of event-based milestone
payments,  (iii)  up  to  $30.0  million  of  variable  consideration  in  the  form  of  sales-based  milestone  payments,  and  (iv)  other  royalty-based  payments  based  on  net  sales. The
event-based  milestone  payments  are  based  on  certain  development  and  regulatory  events  occurring. At  inception,  we  evaluated  whether  the  milestone  conditions  had  been
achieved and if it was probable that a significant revenue reversal would not occur before recognizing the associated revenue and determined that these milestone payments
were not within our control or the licensee’s control, such as regulatory approvals, and were not considered probable of being achieved until those approvals were received.
Accordingly, at inception, we fully constrained the $26.0 million of event-based milestone payments until such time that it is probable that significant revenue reversal would
not occur. The sales-based milestone payments and other royalty-based payments are based on a level of sales for which the license is deemed to be the predominant item to
which the royalties relate. We will recognize revenue for these payments at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some
or all of the royalty has been allocated has been satisfied or partially satisfied. To date, we have not recognized any sales-based or royalty revenue resulting from this licensing
arrangement.

During the year ended December 31, 2021, Taysha achieved an event-based milestone payment and, accordingly, we recognized $3.0 million of revenue as of December 31,
2021. There was no revenue recognized under this agreement during the year ended December 31, 2022. As of December 31, 2022 and 2021, we have a contract asset for nil
and $3.0 million but did not have any contract liabilities as a result of this transaction. We collected the $3.0 million of cash in January 2022 in full satisfaction of the contract
asset.

Sublicense Agreement Relating to Rett Syndrome: In October 2020, we entered into a sublicense agreement with Taysha for a gene therapy for Rett syndrome and MECP2 gene
constructs and regulation of their expression. The agreement grants Taysha worldwide exclusive rights to intellectual property developed by scientists at the University of North
Carolina at Chapel Hill, the University of Edinburgh and us, and our know-how relating to the research, development, and manufacture of the gene therapy for Rett syndrome
and MECP2 gene constructs and regulation of their expression.

We  assessed  the  nature  of  the  promised  license  to  determine  whether  the  license  has  significant  stand-alone  functionality  and  evaluated  whether  such  functionality  can  be
retained without ongoing activities by us and determined that the license has significant stand-alone functionality. Furthermore, we have no ongoing activities associated with
the license to support or maintain the license’s utility. Based on this, we determined that the pattern of transfer of control of the license to Taysha was at a point in time.

The transaction price of the contract includes (i) $3.0 million of fixed consideration, (ii) up to $26.5 million of variable consideration in the form of event-based milestone
payments,  (iii)  up  to  $30.0  million  of  variable  consideration  in  the  form  of  sales-based  milestone  payments,  and  (iv)  other  royalty-based  payments  based  on  net  sales. The
event-based milestone payments are based on certain development and regulatory events occurring. We evaluated whether the milestone conditions have been achieved and if it
is  probable  that  a  significant  revenue  reversal  would  not  occur  before  recognizing  the  associated  revenue. We  determined  that  these  milestone  payments  are  not  within  our
control or the licensee’s control, such as regulatory approvals, and are not considered probable of being achieved until those approvals are received. Accordingly, we have fully
constrained the $26.5 million of event-based milestone payments until such time that it is probable that significant revenue reversal would not occur. The sales-based milestone
payments and other royalty-based payments are based on a level of sales for which the license is deemed to be the predominant item to which the royalties relate. We will
recognize  revenue  for  these  payments  at  the  later  of  (i)  when  the  related  sales  occur,  or  (ii)  when  the  performance  obligation  to  which  some  or  all  of  the  royalty  has  been
allocated has been satisfied or partially satisfied. To date, we have not recognized any sales-based or royalty revenue resulting from this licensing arrangement.

Under  this  arrangement,  we  recognized  $1.0  million  of  revenue  during  the  year  ended  December  31,  2022,  which  amount  related  solely  to  fixed  consideration. We  did  not
recognize any related revenue during the year ended December 31, 2021. As of December 31, 2022 and 2021, we do not have any contract assets or contract liabilities as a
result of this transaction.

Accrued Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and development expenses. This process involves
reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service
performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our service providers
invoice  us  in  arrears  for  services  performed,  on  a  pre-determined  schedule  or  when  contractual  milestones  are  met;  however,  some  require  advanced  payments.  We  make
estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time. There may
be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the clinical expense. If the actual timing of the
performance  of  services  or  the  level  of  effort  varies  from  our  estimate,  we  adjust  the  accrual  or  amount  of  prepaid  expense  accordingly. Although  we  do  not  expect  our
estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of
services performed may vary and may result in us reporting amounts that are too high or too low in any particular period. To date, we have not made any material adjustments
to our prior estimates of accrued research and development expenses.

Share-Based Compensation Expense

We  account  for  share-based  compensation  expense  in  accordance  with ASC  718,  Stock  Based  Compensation.  We  have  two  share-based  compensation  plans  under  which
incentive and qualified stock options and restricted shares may be granted to employees, directors, and consultants. We measure the cost of the employee/director/consultant
services received in exchange for an award of equity instruments based on the fair value for employees and directors and vesting date fair value of the award for consultants.
We use the Black-Scholes option pricing model to determine the fair value of options as of the grant date and the Hull White I lattice model as of any option repricing dates.
The models used to determine the fair value of options includes assumptions for expected volatility, risk-free interest rate, dividend yield and estimated expected term. We use
the closing price of our common stock as quoted on Nasdaq to determine the fair value of restricted stock. We account for forfeitures as they occur, which may result in the
reversal of compensation costs in subsequent periods as the forfeitures arise.

Stock  option-based  compensation  expense  recognized  for  the  years  ended  December  31,  2022  and  2021  was  approximately  $2.0  million  and  $5.3  million,  respectively.
Restricted stock-based compensation expense recognized for the years ended December 31, 2022 and 2021 was approximately $1.1 million and $3.7 million, respectively.

Warrants

We  have  issued  warrants  associated  with  capital  raises  from  time  to  time.  We  determine  the  accounting  and  value  of  any  issued  warrants  in  accordance  with  ASC  480,
Distinguishing Liabilities from Equity and ASC 815, Derivatives and Hedging. The first step is to determine if the warrants are to be classified as either a liability or equity
depending on the warrant terms. The second step is to then determine the value of the warrants. We measure the value of any liability classified warrants on their issuance date
based on their fair value using the Black-Scholes pricing model. The models used to determine the fair value of these warrants includes assumptions for expected volatility,
risk-free interest rate, dividend yield and estimated expected term. The liability classified warrants are revalued on each subsequent balance sheet date until such instruments
are exercised or expire, with any changes in the fair value between reporting periods recorded in the consolidated statements of operations and comprehensive loss.

Change in fair value of warrant liability recognized for the years ended December 31, 2022 and 2021 was approximately $11.4 million and nil, respectively.

Evaluation of Disclosure Controls and Procedures

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 the end of the period covered by
this Annual Report on Form 10-K. Based on such evaluation, our principal executive officer and principal financial officer have concluded that as of such date, our disclosure
controls and procedures were effective.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules
13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive and principal financial officers and
effected  by  our  board  of  directors,  management  and  other  personnel,  to  provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of
financial statements for external purposes in accordance with generally accepted accounting principles 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  generally  accepted

accounting principles, 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
the financial statements. Under the supervision and with the participation of management, including our principal executive and financial officers, we assessed our
internal control over financial reporting as of December 31, 2022, based on criteria for effective internal control over financial reporting established in Internal Control
— Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our management’s assessment of the
effectiveness  of  our  internal  control  over  financial  reporting  included  testing  and  evaluating  the  design  and  operating  effectiveness  of  our  internal  controls.  In  our
management’s opinion, we have maintained effective internal control over financial reporting as of December 31, 2022, based on criteria established in the COSO
2013 framework.

Because we are a non-accelerated filer and smaller reporting company, Whitley Penn LLP, our independent registered public accounting firm, is not required to attest to or issue
a report on the effectiveness of our internal control over financial reporting.

Inherent Limitations of Internal Controls

Our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures or our internal controls
will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of
the  control  system  are  met.  Because  of  the  inherent  limitations  in  all  control  systems,  no  evaluation  of  controls  can  provide  absolute  assurance  that  all  control  issues  and
instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that
breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more
people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and
there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of
changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. 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. Because of the
inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15(d)-15(f) promulgated under the Exchange Act,
during the fourth quarter of 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Abeona Therapeutics Inc. and Subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Abeona Therapeutics Inc. and Subsidiaries (the “Company”) as of December 31, 2022 and 2021, and the
related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred
to  as  the  “financial  statements”).  In  our  opinion,  the  consolidated  financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  as  of
December 31, 2022 and 2021, and the results of their operations and their cash flows for the years then ended, in conformity with accounting principles generally accepted in
the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these 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 entity’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 Matters

Critical  audit  matters  are  matters  arising  from  the  current  period  audit  of  the  financial  statements  that  were  communicated  or  required  to  be  communicated  to  the  audit
committee  and  that:  (1)  relate  to  accounts  or  disclosures  that  are  material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective,  or  complex
judgments. We determined that there are no critical audit matters.

/s/ WHITLEY PENN LLP

We have served as the Company’s auditor since 2006.

ABEONA THERAPEUTICS INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements

NOTE 1 – NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Background

Abeona Therapeutics Inc. (together with the Company’s subsidiaries, “Abeona” or the “Company”), a Delaware corporation, is a clinical-stage biopharmaceutical company
developing  cell  and  gene  therapies  for  life-threatening  diseases.  The  Company’s  lead  clinical  program  is  EB-101,  an  autologous,  engineered  cell  therapy  currently  in
development for recessive dystrophic epidermolysis bullosa (“RDEB”). The Company’s development portfolio also features AAV-based gene therapies designed to treat high
unmet medical need ophthalmic diseases using the novel AIM™ capsid platform that the Company has exclusively licensed from the University of North Carolina at Chapel
Hill, and internal AAV vector research programs.

Reverse Stock Split

On June 30, 2022, the Company filed a Certificate of Amendment to the Company’s Restated Certificate of Incorporation with the Secretary of State of the State of Delaware
(the “Certificate of Amendment”), to effectuate a reverse stock split of the Company’s outstanding common stock, par value $0.01 per share (“Common Stock”), at an exchange
ratio of 25-to-1 (the “Reverse Stock Split”). The Reverse Stock Split was effective on July 1, 2022. The number of authorized shares of Common Stock immediately after the
Reverse Stock Split (“New Common Stock”) remains at 200,000,000 shares. All share and per share information has been retroactively adjusted to give effect to the Reverse
Stock Split for all periods presented, unless otherwise indicated.

As a result of the Reverse Stock Split, every 25 shares of Common Stock outstanding immediately prior to the effectiveness of the Reverse Stock Split were combined and
converted into one share of New Common Stock without any change in the par value per share. No fractional shares were issued in connection with the Reverse Stock Split.
Stockholders who would otherwise be entitled to a fraction of one share of New Common Stock as a result of the Reverse Stock Split instead received an amount in cash equal
to such fraction multiplied by the closing sale price of Common Stock on the Nasdaq Capital Market on July 1, 2022, as adjusted for the Reverse Stock Split.

Proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise or vesting of all stock options, restricted stock and
warrants outstanding at July 1, 2022, which resulted in a proportional decrease in the number of shares of the Company’s common stock reserved for issuance upon exercise or
vesting of such stock options, restricted stock and warrants, and, in the case of stock options and warrants, a proportional increase in the exercise price of all such stock options
and warrants. In addition, the number of shares reserved for issuance under the Company’s 2015 Equity Incentive Plan were reduced proportionately.

Uses and Sources of Liquidity

The consolidated financial statements have been prepared on the going concern basis, which assumes the Company will have sufficient cash to pay its operating expenses, as
and when they become payable, for a period of at least 12 months from the date the financial report is issued.

As of December 31, 2022, the Company had cash, cash equivalents, restricted cash and short-term investments of $52.5 million. For the year ended December 31, 2022, the
Company had cash outflows from operations of $43.5 million. The Company has not generated significant revenues and has not achieved profitable operations. There is no
assurance  that  profitable  operations  will  ever  be  achieved,  and,  if  achieved,  could  be  sustained  on  a  continuing  basis.  In  addition,  development  activities,  clinical  and
nonclinical testing, and commercialization of the Company’s product candidates will require significant additional financing.

The Company is subject to a number of risks similar to other life science companies, including, but not limited to, risks related to the successful discovery and development of
product  candidates,  obtaining  the  necessary  regulatory  approval  to  market  the  Company’s  product  candidates,  raising  additional  capital  to  continue  to  fund  the  Company’s
operations, development of competing drugs and therapies and protection of proprietary technology. As a result of these and other risks and the related uncertainties, there can
be no assurance of the Company’s future success.

F-6

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Company believes that its current cash and cash equivalents, restricted cash and short-term investments are sufficient resources to fund operations through at least the next
12 months from the date of this report on Form 10-K. The Company may need to secure additional funding to carry out all of its planned research and development activities. If
the Company is unable to obtain additional financing or generate license or product revenue, the lack of liquidity and sufficient capital resources could have a material adverse
effect on its future prospects.

Summary of Significant Accounting Policies

A summary of the significant accounting policies applied in the preparation of the accompanying consolidated financial statements follows:

Principles of Consolidation

The consolidated financial statements include the financial statements of Abeona Therapeutics Inc. and the Company’s wholly-owned subsidiaries. All intercompany balances
and transactions have been eliminated in consolidation.

Use of Estimates

The  preparation  of  consolidated  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of America  (“U.S.  GAAP”)  requires
management  to  make  estimates  and  assumptions  that  affect  the  reported  amount  of  assets  and  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  consolidated
financial statements and the reported amounts of revenue and expenses during the reported period. Actual results could differ from these estimates and assumptions.

Reclassifications

Certain comparative figures have been reclassified to conform to the current year presentation. The Company reclassified depreciation and amortization costs of $3.2 million
and  $0.1  million  to  research  and  development  and  general  and  administrative  expenses,  respectively,  on  the  consolidated  statements  of  operations  and  comprehensive  loss
during the year ended December 31, 2021. The Company also reclassified certain rent expenses of $1.2 million from general and administrative to research and development
expenses  on  the  consolidated  statements  of  operations  and  comprehensive  loss  during  the  year  ended  December  31,  2021,  respectively.  Additionally,  the  Company  also
reclassified $5.0 million of restricted cash from prepaid expenses, other current assets and restricted cash and $0.9 million of restricted cash from other assets and restricted
cash to restricted cash on the consolidated balance sheets as of December 31, 2021.

Correction of Error

During 2022, the Company identified errors in the accounting for certain common stock warrants that were issued in 2021. The common stock warrants were not indexed to the
Company’s  own  stock  and  therefore  should  have  been  classified  as  liabilities  at  their  estimated  fair  value  instead  of  additional  paid-in  capital.  Although  the  errors  were
immaterial  to  prior  periods,  the  2021  financial  statements  are  restated  below  in  accordance  with  Staff Accounting  Bulletin  No.  108,  “Considering  the  Effects  of  Prior Year
Misstatements when Quantifying Misstatements in Current Year Financial Statements”, due to the significance of the out-of-period correction to the 2021 period. There was no
impact  to  the  Company’s  consolidated  statements  of  operations  and  comprehensive  loss. The  Company  evaluated  the  materiality  of  these  errors  on  both  a  quantitative  and
qualitative basis under the guidance of ASC 250, “Accounting Changes and Errors Corrections,” and determined that it did not have a material impact on previously issued
financial statements.

A reconciliation of the effects of the restatement to amounts in the previously reported consolidated financial statements for the year ended December 31, 2021 are as follows

Cash and Cash Equivalents

The  Company  considers  all  highly  liquid  investments  with  a  maturity  of  three  months  or  less  when  purchased  to  be  cash  equivalents.  The  Company  maintains  deposits
primarily  in  financial  institutions,  which  may  at  times  exceed  amounts  covered  by  insurance  provided  by  the  U.S.  Federal  Deposit  Insurance  Corporation  (“FDIC”).  The
Company has not experienced any losses related to amounts in excess of FDIC limits.

Restricted Cash

Restricted cash serves as collateral for office space.

Short-term Investments

Short-term  investments  consist  of  investments  in  U.S.  government,  U.S.  agency  and  U.S.  treasury  securities. The  Company  determines  the  appropriate  classification  of  the
securities at the time they are acquired and evaluate the appropriateness of such classifications at each balance sheet date. The Company classifies its short-term investments as
available-for-sale pursuant to Accounting Standards Codification (“ASC”) 320, Investments – Debt and Equity Securities. Investments classified as current have maturities of
less  than  one  year. The  Company  reviews  its  short-term  investments  for  other-than-temporary  impairment  whenever  the  fair  value  of  a  marketable  security  is  less  than  the
amortized cost and evidence indicates that a short-term investment’s carrying amount is not recoverable within a reasonable period of time.

Property and Equipment

Property and equipment are recorded at cost. Depreciation is provided using the straight-line method over estimated useful lives ranging from three to seven years. Leasehold
improvements  are  amortized  over  the  shorter  of  the  asset’s  useful  life  or  the  life  of  the  lease  term  ranging  from  five  to  ten  years.  Expenditures  for  major  renewals  and
betterments that extend the useful lives are capitalized. Expenditures for normal maintenance and repairs are expensed as incurred. The cost of assets sold or abandoned, and the
related accumulated depreciation are eliminated from the accounts and any gains or losses are recognized in the accompanying consolidated statements of operations of the
respective period.

Leases

The Company accounts for leases in accordance with ASC 842, Leases. Right-of-use lease assets represent the Company’s right to use an underlying asset for the lease term
and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The measurement of lease liabilities is based on the present value of
future lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information
available at the lease commencement date in determining the present value of future lease payments. The right-of-use asset is based on the measurement of the lease liability
and includes any lease payments made prior to or on lease commencement and excludes lease incentives and initial direct costs incurred, as applicable. Rent expense for the
Company’s operating leases is recognized on a straight-line basis over the lease term. The Company does not have any leases classified as finance leases.

The  Company’s  leases  do  not  have  significant  rent  escalation,  holidays,  concessions,  material  residual  value  guarantees,  material  restrictive  covenants  or  contingent  rent
provisions. The Company’s leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other
maintenance costs), which are accounted for as a single lease component as the Company has elected the practical expedient to group lease and non-lease components for all
leases.

Most leases include one or more options to renew. The exercise of lease renewal options is typically at the Company’s sole discretion; therefore, the majority of renewals to
extend the lease terms are not included in the Company’s right-of-use assets and lease liabilities as they are not reasonably certain of exercise. The Company regularly evaluates
the renewal options and when they are reasonably certain of exercise, the Company includes the renewal period in its lease term.

Licensed Technology

The  Company  has  entered  into  agreements  to  license  the  rights  to  certain  technologies. The  Company  records  the  purchase  price  paid  for  the  license,  which  represents  fair
value,  on  its  consolidated  balance  sheet.  Licensed  technology  is  amortized  over  the  life  of  the  patent  or  the  agreement.  The  Company  maintain  licensed  technology  on  its
consolidated balance sheet until either the licensed technology agreement underlying it is completed or the asset becomes impaired. When the Company determine that an asset
has become impaired, as discussed below, or the Company abandons a project, the Company writes down the carrying value of the related intangible asset to its fair value and
recognizes an impairment charge in the period in which the impairment occurs.

Impairment of Long-Lived Assets

Long-lived  assets  consist  of  property  and  equipment,  licensed  technology,  and  right-of-use  assets. The  Company  tests  its  long-lived  assets  for  impairment  when  events  and
circumstances indicate that the carrying value of an asset or group of assets may not be fully recoverable. If indicators are present or changes in circumstance suggest that
impairment may exist, the Company assesses the recoverability of the affected long-lived assets or group of assets by determining whether the carrying value of such assets or
group  of  assets  can  be  recovered  through  undiscounted  future  operating  cash  flows.  If  the  carrying  amount  is  not  recoverable,  the  Company  measures  the  amount  of  any
impairment by comparing the carrying value of the asset or group of assets to its fair value.

Goodwill

Goodwill represents the excess of the purchase price of acquired businesses over the estimated fair value of the identifiable net assets acquired. Goodwill is not amortized but is
tested for impairment at least annually at the reporting unit level or more frequently if events or changes in circumstances indicate that the asset might be impaired. Impairment
loss, if any, is recognized based on a comparison of the fair value of the asset to its carrying value, without consideration of any recoverability. The Company tests goodwill for
impairment annually during the fourth quarter and whenever indicators of impairment exist by first assessing qualitative factors to determine whether it is more likely than not
that the fair value is less than its carrying amount. If the Company concludes it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a
quantitative impairment test is performed. If the Company concludes that goodwill is impaired, it will record an impairment charge in its consolidated statement of operations
and comprehensive loss.

Segments

The Company operates in a single segment. The Company’s chief operating decision maker, its Chief Executive Officer, manages the Company’s operations on a consolidated
basis for the purpose of allocating resources.

Revenue Recognition

The Company accounts for contracts with customers in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). ASC 606 applies to all contracts with
customers, except for contracts that are within the scope of other standards. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods
or  services,  in  an  amount  that  reflects  the  consideration  that  the  entity  expects  to  receive  in  exchange  for  those  goods  or  services.  To  determine  revenue  recognition  for
arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the
performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize
revenue when (or as) the entity satisfies a performance obligation.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development expenses include, but are not limited to, payroll and personnel expense, lab supplies,
preclinical  and  development  cost,  clinical  trial  expense,  manufacturing,  regulatory,  and  consulting.  The  cost  of  materials  and  equipment  or  facilities  that  are  acquired  for
research and development activities and that have alternative future uses are capitalized when acquired.

General and Administrative Expenses

General  and  administrative  expenses  primarily  consist  of  personnel,  contract  personnel,  personnel-related  expenses  to  support  the  Company’s  administrative  and  operating
activities, facility costs and professional expenses (i.e., legal expenses) and investor relations fees.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences
between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards.
Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation
allowance is provided for deferred tax assets to the extent their realization is in doubt.

The Company accounts for uncertain income tax positions in accordance with ASC 740, Income Taxes. Interest costs and penalties related to income taxes are classified as
interest expense and general and administrative costs, respectively, in the consolidated financial statements. For 2022 and 2021, the Company did not recognize any uncertain
tax positions, interest or penalty expense related to income taxes. It is not reasonably likely for the amounts of unrecognized tax benefits to significantly increase or decrease
within the next 12 months. The Company files U.S. federal and state income tax returns as necessary. The federal return generally has a three-year statute of limitations and
most states have a four-year statute of limitations; however, the taxing authorities are allowed to review the tax year in which the net operating loss was generated when the loss
is utilized on a tax return. The Company currently does not have any open income tax audits.

Net Loss Per Share

Basic and diluted net loss per share is computed by dividing net loss attributable to common shareholders by the weighted-average number of shares of common stock. The
Company does not include the potential impact of dilutive securities in diluted net loss per share, as the impact of these items is anti-dilutive. Potential dilutive securities result
from outstanding restricted stock, stock options, and stock purchase warrants.

The following table sets forth the potential securities that could potentially dilute basic income/(loss) per share in the future that were not included in the computation of diluted
net loss per share because to do so would have been anti-dilutive for the periods presented:

1,788,000 
2,202,655 

The  Company  accounts  for  stock-based  compensation  expense  in  accordance  with  ASC  718,  Stock  Based  Compensation.  The  Company  measures  the  cost  of  the
employee/director/consultant services received in exchange for an award of equity instruments based on the grant date fair value for the employees and directors and vesting
date fair value for consultants of the award. The Company uses the Black-Scholes option pricing model to determine the fair value of options on the grant date which includes
assumptions for expected volatility, risk-free interest rate, dividend yield and estimated expected term. The Company uses the closing price of its common stock as quoted on
the  Nasdaq  to  determine  the  fair  value  of  restricted  stock.  The  Company  accounts  for  forfeitures  as  they  occur,  which  may  result  in  the  reversal  of  compensation  costs  in
subsequent periods as the forfeitures arise.

Warrants

On  November  3,  2022,  the  Company  issued  warrants  to  purchase  7,609,879  shares  of  common  stock,  with  an  exercise  price  of  $4.75  per  share,  subject  to  customary
adjustments thereunder. On December 17, 2021, the Company issued warrants to purchase 1,788,000 shares of common stock, with an exercise price of $9.75 (post-split) per
share, subject to customary adjustments thereunder. The warrants issued in 2022 and 2021 were determined to be freestanding instruments as they are legally detachable and
separately exercisable from each other and from the common stock issued.

The common stock warrants are accounted for as liabilities on the consolidated balance sheets at their estimated fair value because they are not indexed to the Company’s own
stock. The warrants are revalued on each subsequent balance sheet date until such instruments are exercised or expire, with any changes in the fair value between reporting
periods recorded in the consolidated statements of operations and comprehensive loss.

Recently Adopted 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): Accounting  for  Convertible  Instruments  and  Contracts  in  an  Entity’s  Own  Equity”  (“ASU  2020-06”),  which  simplifies  the  accounting  for
convertible instruments by eliminating the requirement to separately account for embedded conversion features as an equity component in certain circumstances. A convertible
debt instrument will be reported as a single liability instrument with no separate accounting for an embedded conversion feature unless separate accounting is required for an
embedded conversion feature as a derivative or under the substantial premium model. The ASU simplifies the diluted earnings per share calculation by requiring that an entity
use  the  if-converted  method  and  that  the  effect  of  potential  share  settlement  be  included  in  diluted  earnings  per  share  calculations.  Further,  the  ASU  requires  enhanced
disclosures  about  convertible  instruments.  The  Company  adopted  ASU  2020-06  as  of  January  1,  2022,  and  there  was  no  material  impact  on  the  consolidated  financial
statements upon adoption.

As of December 31, 2022, the available-for-sale securities classified as short-term investments mature in one year or less. Unrealized losses on available-for-sale securities as of
December 31, 2022 were not significant and were primarily due to changes in interest rates, including market credit spreads, and not due to increased credit risks associated
with specific securities. None of the short-term investments have been in a continuous unrealized loss position for more than 12 months. Accordingly, no other-than-temporary
impairment was recorded for the year ended December 31, 2022.

There were no significant realized gains or losses recognized on the sale or maturity of available-for-sale investments during the years ended December 31, 2022 or 2021.

Depreciation and amortization on property and equipment was $3.1 million and $3.3 million for 2022 and 2021, respectively. During the year ended December 31, 2022, the
Company incurred a loss on disposal of equipment of $0.1 million which is reflected in other income (expense) in the consolidated statements of operations and comprehensive
loss.

On March 31, 2022, the Company announced that it was pursuing a strategic partner to take over development activities of ABO-102 and that it was discontinuing development
of ABO-101. As  a  result,  the  Company  determined  the  construction-in-progress  that  was  dedicated  to  the ABO-101  and ABO-102  programs  had  no  future  value,  and  thus
recorded an impairment charge of $1.8 million for the year ended December 31, 2022, which was net of a cash refund from the builder of approximately $1.5 million.

NOTE 4 – LICENSED TECHNOLOGY

On May 15, 2015, the Company acquired Abeona Therapeutics LLC, which had an exclusive license through Nationwide Children’s Hospital to the AB-101 and AB-102 patent
portfolios for developing treatments for patients with Sanfilippo Syndrome Type A and Type B. The license is amortized over the life of the license of 20 years. On March 31,
2022, the Company announced that it was pursuing a strategic partner to take over development activities of ABO-102 and that it was discontinuing development of ABO-101.
As a result, the Company determined the remaining value of the licensed technology had no future value and thus recorded an impairment charge of $1.4 million for the year
ended December 31, 2022.

As there was no recorded goodwill as of December 31, 2022, the Company did not perform its annual goodwill impairment test for 2022. The Company completed its annual
goodwill impairment test as of year-end 2021 and determined that the carrying value of its net assets exceeded fair value using its market capitalization as a proxy for fair value.
In accordance with ASC 350, the Company recognized an impairment loss for the excess of the carrying value over the fair value but limited to the total amount of goodwill
recorded on its consolidated balance sheet. As a result, the Company recorded a goodwill impairment charge of $32.5 million for the year ended December 31, 2021.

NOTE 6 – FAIR VALUE MEASUREMENTS

The  Company  calculates  the  fair  value  of  the  Company’s  assets  and  liabilities  that  qualify  as  financial  instruments  and  includes  additional  information  in  the  notes  to  the
consolidated financial statements when the fair value is different than the carrying value of these financial instruments. The estimated fair value of accounts receivable, prepaid
expenses and other current assets, other assets, accounts payable, accrued expenses, payables to licensor and deferred revenue approximate their carrying amounts due to the
relatively short maturity of these instruments.

U.S. GAAP 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  at  the  measurement  date.  This  guidance  establishes  a  three-level  fair  value  hierarchy  that
prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The
three levels of inputs used to measure fair value are as follows:

● Level 1 - Quoted prices in active markets for identical assets or liabilities.

● Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for

identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

● Level  3  -  Unobservable  inputs  that  are  supported  by  little  or  no  market  activity  and  that  are  significant  to  the  fair  value  of  the  assets  and  liabilities. This  includes

certain pricing models, discounted cash flow methodologies and similar valuation techniques that use significant unobservable inputs.

The Company has segregated all financial assets and liabilities that are measured at fair value on a recurring basis (at least annually) into the most appropriate level within the
fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the table below.

The following table provides a summary of financial assets measured at fair value on a recurring and non-recurring basis (in thousands):

Warrant Liabilities

The warrant liabilities are valued using significant inputs not observable in the market. Accordingly, the warrant liability is measured at fair value on a recurring basis using
unobservable inputs and are classified as Level 3 inputs within the fair value hierarchy. Fair value measurements categorized within Level 3 are sensitive to changes in the
assumptions or methodology used to determine fair value and such changes could result in a significant increase or decrease in the fair value. The Company’s valuation of the
common stock warrants utilized the Black-Scholes option-pricing model, which incorporated assumptions and estimates to value the common stock warrants. The Company
assessed these assumptions and estimates at the end of each reporting period. Assumptions used to estimate the fair value of the warrants in the Black-Scholes option-pricing
model are as follows:

Common share price
Expected term (years)
Risk-free interest rate (%)
Volatility (%)

On May 2, 2020, the Company received loan proceeds in the amount of approximately $1.8 million (the “PPP Loan”) under the Paycheck Protection Program (“PPP”). The PPP
was established under the Coronavirus Aid, Relief and Economic Security Act, as amended (“CARES Act”) and is administered by the U.S. Small Business Administration
(“SBA”). Under the terms of the CARES Act, PPP loan recipients can apply for loan forgiveness. The loan forgiveness for all or a portion of PPP loans was determined, subject
to limitations, based on the use of loan proceeds over the 24 weeks after the loan proceeds are disbursed. In July 2021, the Company received notice from the SBA that its PPP
loan was forgiven. The extinguishment of the PPP loan payable was recorded as PPP loan payable forgiveness income in the statement of operations and comprehensive loss
and as non-cash PPP loan payable forgiveness income in the statements of cash flows during the year ended December 31, 2021.

NOTE 8 – SETTLEMENT LIABILITY

On November 4, 2018, the Company entered into a license agreement with REGENXBIO Inc. (“REGENXBIO”) to obtain rights to an exclusive worldwide license (subject to
certain non-exclusive rights previously granted for MPS IIIA), with rights to sublicense, to REGENXBIO’s NAV AAV9 vector for gene therapies for treating MPS IIIA, MPS
IIIB, CLN1 Disease and CLN3 Disease. Consideration for the rights granted under the original agreement included fees totaling $180 million and a running royalty on net
sales, including: (i) an initial fee of $20 million, $10 million of which was due to REGENXBIO shortly after the effective date of the agreement, and $10 million of which was
to  be  due  on  the  first  anniversary  of  the  effective  date  of  the  agreement  in  November  2019,  (ii)  annual  fees  totaling  up  to  $100  million,  payable  in  $20  million  annual
installments beginning on the second anniversary of the effective date (the first of which was to remain payable if the agreement were terminated before the second anniversary
in November 2020), (iii) sales milestone payments totaling $60 million, and (iv) royalties payable in the low double digits to low teens on net sales of products covered under
the agreement. The license was being amortized over the life of the patent of eight years. On November 1, 2019, the Company entered into an amendment of the original license
agreement. The amended agreement replaced the $10 million payment due on November 4, 2019 with a $3 million payment due on November 4, 2019 and an additional $8
million payment (which included $1 million of interest) that would have been due no later than April 1, 2020. That $8 million payment that had been scheduled to be paid by
April 1, 2020 and the $20 million payment that had been due to be paid on November 4, 2020 were both recorded as payable to licensor on the consolidated balance sheet. The
Company  disputed  that  it  was  responsible  for  the  $8  million  and  $20  million  payments,  and  those  payments  were  the  subject  of  an  arbitration  between  the  Company  and
REGENXBIO.

Prior to the April 1, 2020 deadline, the Company engaged REGENXBIO in discussions in an attempt to renegotiate the financial terms of the agreement, but the Company was
unable to reach an agreement, and did not make the $8 million payment due by April 1, 2020. On April 17, 2020, REGENXBIO sent the Company a written demand for the $8
million fee, payable within a 15-day cure period after receipt of the demand letter. The license terminated on May 2, 2020, when the 15-day period expired.

On November 12, 2021, the Company entered into a settlement agreement (“Settlement Agreement”) with REGENXBIO to resolve all existing disputes between the parties. In
accordance with the Settlement Agreement, the Company agreed to pay REGENXBIO a total of $30.0 million, payable as follows: (1) $20.0 million paid in November 2021
after execution of the Settlement Agreement, (2) $5.0 million on the first anniversary of the effective date of the Settlement Agreement, and (3) $5.0 million upon the earlier of
(i)  the  third  anniversary  of  the  effective  date  of  the  Settlement Agreement  or  (ii)  the  closing  of  a  Strategic Transaction,  as  defined  in  the  Settlement Agreement.  Under  the
Settlement Agreement’s terms, the prior license agreement between the parties is not reinstituted, and any future license agreement would need to be negotiated separately and
require consideration in addition to the consideration set forth in the Settlement Agreement. The accounting for the Settlement Agreement resulted in a $6.7 million gain on
settlement with licensor in the statements of operations and comprehensive loss during the year ended December 31, 2021 and a $6.7 million non-cash gain on settlement with
licensor in the statements of cash flows during the year ended December 31, 2021.

As of December 31, 2022 and 2021, the Company recorded the payables due to REGENXBIO in the consolidated balance sheets based on the present value of the remaining
payments due to REGENXBIO under the Settlement Agreement using an interest rate of 9.6%. The current portion of the payable due in November 2022 was nil and $4.6
million as of December 31, 2022 and 2021, respectively and the long-term portion due in November 2024 was $4.2 million and $3.8 million as of December 31, 2022 and
2021, respectively. As of December 31, 2021, the Company recorded $5.0 million of restricted cash in the consolidated balance sheet that served as collateral for the payment
made to REGENXBIO in November 2022.

The Company leases space under operating leases for manufacturing and laboratory facilities in Cleveland, Ohio, as well as administrative offices in New York, New York. The
Company also leases certain office equipment under operating leases, which have a non-cancelable lease term of less than one year and, therefore, the Company has elected the
practical expedient to exclude these short-term leases from the Company’s right-of-use assets and lease liabilities.

During 2022, the Company announced a strategic partner to take over development activities of ABO-102 and that the Company was discontinuing development of ABO-101.
As a result, the Company determined the portion of the lease that was dedicated to the future facility for the ABO-101 and ABO-102 programs, had no future value and thus,
the Company recorded an impairment charge of $1.6 million for the year ended December 31, 2022.

In November 2022, the Company entered into a sublease agreement with an unrelated third party to occupy approximately 5,700 square feet of the Company’s administrative
offices  in  New  York,  New  York.  Because  the  future  sublease  income  under  the  executed  sublease  agreement  is  less  than  the  amount  the  Company  pays  its  landlord,  the
Company recorded an impairment charge of $0.9 million for the year ended December 31, 2022. The Company expects to receive approximately $1.1 million in future sublease
income through September 2025.

NOTE 11 – EQUITY

Series A and B Convertible Redeemable Preferred Stock

On  May  2,  2022,  the  Company  consummated  an  offering  with  certain  institutional  investors  for  the  private  placement  of  1,000,006  shares  of  the  Company’s  Series  A
Convertible Redeemable Preferred Stock (the “Series A Preferred Stock”) and 250,005 shares of the Company’s Series B Convertible Redeemable Preferred Stock (the “Series
B  Preferred  Stock”  and  together  with  the  Series  A  Preferred  Stock,  the  “Preferred  Stock”).  The  shares,  which  have  since  been  redeemed  in  accordance  with  their  terms
described below and are thus no longer outstanding as of December 31, 2022, had an aggregated stated value of $25.0 million. Each share of the Preferred Stock had a purchase
price  of  $19.00,  representing  an  original  issue  discount  of  5%  of  the  stated  value.  In  connection  with  this  offering,  the  Company  had  net  proceeds  of  $22.5  million  and
recognized a deemed dividend of $3.8 million. In connection with this transaction, the Company placed $26.3 million into an escrow account for any future redemption which
consisted of the gross proceeds of $25.0 million and the redemption value of $1.3 million.

The Preferred Stock was convertible, at the option of the holders and, in certain circumstances, by the Company, into shares of Common Stock at a conversion price of $11.25
per share. The holders of the Series A Preferred Stock and Series B Preferred Stock had the right to require the Company to redeem their shares of preferred stock for cash at
105%  of  the  stated  value  of  such  shares  commencing  after  the  earlier  of  the  receipt  of  stockholder  approval  of  an  amendment  to  the  Company’s  Restated  Certificate  of
Incorporation to effect a reverse stock split and 60 days after the closing of the issuances of the Series A Preferred Stock and Series B Preferred Stock and until 90 days after
such closing. The Company had the option to redeem the Series A Preferred Stock for cash at 105% of the stated value commencing after the 90th day following the closing of
the  issuance  of  the  Series A  Preferred  Stock,  subject  to  the  holders’  rights  to  convert  the  shares  prior  to  such  redemption. As  a  result,  the  Preferred  Stock  was  recorded
separately from stockholders’ equity because it was redeemable upon the occurrence of redemption events that were considered not solely withing the Company’s control. As
such, during the year ended December 31, 2022, the Company recognized approximately $3.8 million in deemed dividends related to the Preferred Stock in the consolidated
statements of operations and comprehensive loss and the consolidated statements of changes in stockholders’ equity.

On June 17, 2022, the holders of all 1,000,006 shares of Series A Preferred Stock and 250,005 shares of Series B Preferred Stock exercised their right to cause the Company to
redeem all such shares for $26.3 million, which represented a price equal to 105% of the stated value. The redemption of these shares was paid out of the escrow account noted
above.

Common Stock and Warrants

Reverse Stock Split

Effective July 1, 2022, the Company’s stock underwent a 25:1 Reverse Stock Split. The number of authorized shares of Common Stock immediately after the Reverse Stock
Split remained at 200,000,000 shares.

Public Offerings

On December 21, 2021, the Company closed an underwritten public offering of 1,788,000 post-split shares of common stock at a public offering price of $9.75 post-split per
share and stock purchase warrants to purchase 1,788,000 post-split shares of common stock at an exercise price of $9.75 post-split. The net proceeds to the Company were
approximately $16.0 million, after deducting $1.5 million of underwriting discounts and commissions and offering expenses payable by the Company. The net proceeds were
allocated to the warrant liability as noted below with the remainder of $7.0 million recorded in common stock and additional paid-in capital. In the event of certain fundamental
transactions  involving  the  Company,  the  holders  of  the  stock  purchase  warrants  may  require  the  Company  to  make  a  payment  based  on  a  Black-Scholes  valuation,  using
specific inputs that are not considered indexed to the Company’s stock in accordance with ASC 815, Derivatives and Hedging (“ASC 815”). Therefore, the Company accounted
for the stock purchase warrants as liabilities and were recorded at the closing date fair value of $9.0 million which was based on a Black-Scholes option pricing model. The
remainder of the proceeds were allocated to common stock issued and recorded as a component of equity.

As of December 31, 2022, there were 1,788,000 post-split stock purchase warrants issued in connection with the public offering outstanding. These stock purchase warrants
expire on December 21, 2026. During such time as each warrant is outstanding, the holder of the warrant is entitled to participate in any dividends or other distribution of assets
to holders of shares of common stock. There was no warrant activity during the year ended December 31, 2022.

Open Market Sale Agreement

On August 17, 2018, the Company entered into an open market sale agreement with Jefferies LLC (as amended, the “ATM Agreement”) pursuant to which, the Company may
sell from time to time, through Jefferies LLC, shares of its common stock for an aggregate sales price of up to $150.0 million. Any sales of shares pursuant to this agreement
are made under the Company’s effective “shelf” registration statement on Form S-3 that is on file with and has been declared effective by the SEC. The Company is currently
subject to General Instruction I.B.6 of Form S-3, as a result of which the amount of funds the Company can raise through primary public offerings of securities in any 12-month
period using its registration statement on Form S-3 is limited to one-third of the aggregate market value of the voting and non-voting common equity held by non-affiliates. The
Company remains subject to this one-third limitation until such time as its public float exceeds $75 million. The Company sold 3,479,016 and 146,872 post-split shares during
the years ended December 31, 2022 and 2021, respectively, of its common stock under the ATM Agreement and received $12.8 million and $8.1 million of net proceeds during
the years ended December 31, 2022 and 2021, respectively.

Private Placement Offerings

On November 3, 2022, the Company sold 7,065,946 shares of its common stock, and in lieu of shares of common stock, pre-funded warrants exercisable for 543,933 shares of
common stock, and accompanying warrants to purchase 7,609,879 shares of its common stock to a group of new and existing institutional investors in a private placement. The
offering price for each share of common stock and accompanying warrant was $4.60, and the offering price for each pre-funded warrant and accompanying warrant was $4.59,
which  equaled  the  offering  price  per  share  of  the  common  stock  and  accompanying  warrant,  less  the  $0.01  per  share  exercise  price  of  each  pre-funded  warrant.  Each
accompanying warrant represents the right to purchase one share of the Company’s common stock at an exercise price of $4.75 per share of common stock. The pre-funded
warrants were exercised in December 2022 and converted to 543,933 shares of commons stock. Total shares sold and converted during the year ended December 31, 2022 were
7,609,879  for  an  aggregate  purchase  price  of  $35.0  million  gross,  or  $32.6  million  net  of  related  costs  of  $1.5  million  which  was  expensed  to  general  and  administrative
expenses and $0.9 million which was recorded as a reduction to additional paid-in-capital. The net proceeds were allocated to the warrant liability as noted below with the
remainder of $12.9 million and $0.1 million recorded in additional paid-in capital and common stock, respectively. In the event of certain fundamental transactions involving
the Company, the holders of the stock purchase warrants may require the Company to make a payment based on a Black-Scholes valuation, using specific inputs that are not
considered indexed to the Company’s stock in accordance with ASC 815. Therefore, the Company accounted for the stock purchase warrants as liabilities and were recorded at
the closing date fair value of $22.0 million which was based on a Black-Scholes option pricing model. The remainder of the proceeds were allocated to common stock issued
and recorded as a component of equity.

As of December 31, 2022, there were 7,609,879 warrants outstanding related to this private placement offering. The warrants expire on November 3, 2027. During such time as
each warrant is outstanding, the holder of the warrant is entitled to participate in any dividends or other distribution of assets to holders of shares of common stock.

NOTE 12 – LICENSE/SUPPLIER AGREEMENTS

Sublicense and Inventory Purchase Agreements Relating to CLN1 Disease

In August 2020, the Company entered into sublicense and inventory purchase agreements with Taysha Gene Therapies (“Taysha”) relating to a potential gene therapy for CLN1
disease.  Under  the  sublicense  agreement,  Taysha  received  worldwide  exclusive  rights  to  intellectual  property  and  know-how  relating  to  the  research,  development,  and
manufacture  of  the  potential  gene  therapy,  which  the  Company  had  referred  to  as ABO-202.  Under  the  inventory  purchase  agreement,  the  Company  sold  to Taysha  certain
inventory and other items related to ABO-202. The Company assessed these contracts at contract inception and determined that, under ASC 606, the two contracts would be
combined and accounted for as a single contract, with a single performance obligation. The Company assessed the nature of the promised license to determine whether the
license has significant stand-alone functionality and evaluated whether such functionality can be retained without ongoing activities by the Company and determined that the
license has significant stand-alone functionality. Furthermore, the Company has no ongoing activities associated with the license to support or maintain the license’s utility.
Based on this, the Company determined that the pattern of transfer of control of the license to Taysha was at a point in time.

F-18

 
 
 
 
 
 
 
 
 
 
The transaction price of the contract includes (i) $7.0 million of fixed consideration, (ii) up to $26.0 million of variable consideration in the form of event-based milestone
payments,  (iii)  up  to  $30.0  million  of  variable  consideration  in  the  form  of  sales-based  milestone  payments,  and  (iv)  other  royalty-based  payments  based  on  net  sales. The
event-based milestone payments are based on certain development and regulatory events occurring. At inception, the Company evaluated whether the milestone conditions had
been  achieved  and  if  it  was  probable  that  a  significant  revenue  reversal  would  not  occur  before  recognizing  the  associated  revenue  and  determined  that  these  milestone
payments  were  not  within  the  Company’s  control  or  the  licensee’s  control,  such  as  regulatory  approvals,  and  were  not  considered  probable  of  being  achieved  until  those
approvals were received. Accordingly, at inception, the Company fully constrained the $26.0 million of event-based milestone payments until such time that it is probable that
significant  revenue  reversal  would  not  occur.  The  sales-based  milestone  payments  and  other  royalty-based  payments  are  based  on  a  level  of  sales  for  which  the  license  is
deemed to be the predominant item to which the royalties relate. The Company will recognize revenue for these payments at the later of (i) when the related sales occur, or (ii)
when the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied. To date, the Company has not recognized any
sales-based or royalty revenue resulting from this licensing arrangement.

Under  this  arrangement,  the  Company  recognized  nil  and  $3.0  million  in  revenue  during  the  year  ended  December  31,  2022  and  2021,  respectively  based  on  event-based-
milestone  payments.  The  Company  has  no  contract  assets  as  of  December  31,  2022  and  $3.0  million  as  of  December  31,  2021.  Contract  assets  are  included  in  accounts
receivable on the consolidated balance sheets. As of December 31, 2022 and 2021, the Company does not have any contract liabilities as a result of this transaction.

Sublicense Agreement Relating to Rett Syndrome:

In  October  2020,  the  Company  entered  into  a  sublicense  agreement  with Taysha  for  a  gene  therapy  for  Rett  syndrome  and  MECP2  gene  constructs  and  regulation  of  their
expression. The  agreement  grants Taysha  worldwide  exclusive  rights  to  intellectual  property  developed  by  scientists  at  the  University  of  North  Carolina  at  Chapel  Hill,  the
University of Edinburgh and the Company, and the Company’s know-how relating to the research, development, and manufacture of the gene therapy for Rett syndrome and
MECP2 gene constructs and regulation of their expression.

The Company assessed the nature of the promised license to determine whether the license has significant stand-alone functionality and evaluated whether such functionality
can be retained without ongoing activities by the Company and determined that the license has significant stand-alone functionality. Furthermore, the Company has no ongoing
activities associated with the license to support or maintain the license’s utility. Based on this, the Company determined that the pattern of transfer of control of the license to
Taysha was at a point in time.

The transaction price of the contract includes (i) $3.0 million of fixed consideration, (ii) up to $26.5 million of variable consideration in the form of event-based milestone
payments,  (iii)  up  to  $30.0  million  of  variable  consideration  in  the  form  of  sales-based  milestone  payments,  and  (iv)  other  royalty-based  payments  based  on  net  sales. The
event-based  milestone  payments  are  based  on  certain  development  and  regulatory  events  occurring.  The  Company  evaluated  whether  the  milestone  conditions  have  been
achieved and if it is probable that a significant revenue reversal would not occur before recognizing the associated revenue. The Company determined that these milestone
payments are not within the Company’s control or the licensee’s control, such as regulatory approvals, and are not considered probable of being achieved until those approvals
are received. Accordingly, the Company has fully constrained the $26.5 million of event-based milestone payments until such time that it is probable that significant revenue
reversal  would  not  occur.  The  sales-based  milestone  payments  and  other  royalty-based  payments  are  based  on  a  level  of  sales  for  which  the  license  is  deemed  to  be  the
predominant  item  to  which  the  royalties  relate.  The  Company  will  recognize  revenue  for  these  payments  at  the  later  of  (i)  when  the  related  sales  occur,  or  (ii)  when  the
performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied. To date, the Company has not recognized any sales-based
or royalty revenue resulting from this licensing arrangement.

Under  this  arrangement,  the  Company  recognized  $1.0  million  and  nil  in  revenue  during  the  year  ended  December  31,  2022  and  2021,  respectively  based  on  event-based-
milestone payments. As of December 31, 2022 and 2021, the Company does not have any contract assets or contract liabilities as a result of this transaction.

Ultragenyx License Agreement

On  May  16,  2022,  the  Company  and  Ultragenyx  Pharmaceutical  Inc.  (“Ultragenyx”)  entered  into  an  exclusive  license  agreement  (the  “License Agreement”)  for AAV  gene
therapy ABO-102 for the treatment of Sanfilippo syndrome type A (MPS IIIA). Under the License Agreement, Ultragenyx assumed responsibility for the ABO-102 program
from the Company, with the exclusive right to develop, manufacture, and commercialize ABO-102 worldwide. Also pursuant to the License Agreement, following regulatory
approval, the Company is eligible to receive tiered royalties from mid-single-digit up to 10% on net sales and up to $30.0 million in commercial milestone payments. Both
forms of consideration comprise the transaction price to which the Company expects to be entitled in exchange for transferring the related intellectual property and certain,
contractually-specified transition services to Ultragenyx. The sales-based royalty and milestone payments are subject to the royalty recognition constraint. As such, these fees
are not recognized as revenue until the later of: (a) the occurrence of the subsequent sale, and (b) the performance obligation to which they relate has been satisfied.

Additionally, pursuant to the License Agreement, Ultragenyx will reimburse the Company for certain development and transition costs actually incurred by the Company. These
costs  are  passed  through  to  Ultragenyx  without  mark-up.  The  Company  has  determined  that  these  costs  are  not  incurred  for  the  purpose  of  satisfying  any  performance
obligation under the License Agreement. Accordingly, the reimbursement of these costs is recognized as a reduction of research and development costs. As of December 31,
2022 and 2021, the Company does not have any contract assets or contract liabilities as a result of this transaction.

NOTE 13 – STOCK-BASED COMPENSATION

The  Company  has  two  stock-based  compensation  plans:  (1)  Abeona  Therapeutics  Inc.  2015  Equity  Incentive  Plan  (the  “2015  Incentive  Plan”),  which  was  approved  by
stockholders on May 7, 2015, and last amended on August 31, 2022 and (2) Abeona Therapeutics Inc. 2005 Equity Incentive Plan (the “2005 Incentive Plan”), under which no

The Company estimates the fair value of each option award on the date of grant using the Black-Scholes option valuation model. The Company then recognize the grant date
fair value of each option as compensation expense ratably using the straight-line attribution method over the service period (generally the vesting period). The Black-Scholes
model incorporates the following assumptions:

● Expected volatility – the Company estimates the volatility of the share price at the date of grant using a “look-back” period which coincides with the expected term,
defined below. The Company believes using a “look-back” period which coincides with the expected term is the most appropriate measure for determining expected
volatility.

● Expected  term  –  the  Company  estimates  the  expected  term  using  the  “simplified”  method,  as  outlined  in  SEC  Staff Accounting  Bulletin  No.  107,  “Share-Based

Payment.”

● Risk-free interest rate – the Company estimates the risk-free interest rate using the U.S. Treasury yield curve for periods equal to the expected term of the options in

effect at the time of grant.

● Dividends – the Company uses an expected dividend yield of zero because the Company has not declared nor paid a cash dividend, nor are there any plans to declare a

dividend.

The aggregate intrinsic value of options is calculated as the difference between the exercise price of the underlying options and the fair value of the Company’s common stock
for those options that had exercise prices lower than the fair value of the Company’s common stock. As of December 31, 2022, the total compensation cost related to non-
vested option awards not yet recognized was approximately $2.8 million with a weighted average remaining vesting period of 2.1 years.

NOTE 14 – 401(k) PLAN

The Company has a tax-qualified employee savings and retirement plan (the “401(k) Plan”) covering all the Company’s employees in the United States. Pursuant to the 401(k)
Plan, employees may elect to reduce their current compensation by up to the statutorily prescribed annual limit ($20,500 in 2022 and $19,500 in 2021 for employees who are
under age 50 and $27,000 in 2022 and $26,000 in 2021 for employees who are age 50 and older) and to have the amount of such reduction contributed to the 401(k) Plan. The
401(k) Plan is intended to qualify under Section 401 of the Internal Revenue Code so that contributions by employees or by us to the 401(k) Plan, and income earned on 401(k)
Plan contributions, are not taxable to employees until withdrawn from the 401(k) Plan, and so that contributions by us, if any, will be deductible by us when made. At the
direction of each participant, the Company invests the assets of the 401(k) Plan in any of over 50 investment options. Company contributions under the 401(k) Plan were $0.3
million and $0.4 million for the years ended December 31, 2022 and 2021, respectively.

Losses incurred post 2017 do not expire and can only be used to offset 80% of taxable income in any tax year. As of December 31, 2022, the Company had approximately
$245.0 million of net operating loss carryforwards that do not expire and can be carried forward indefinitely. Such net operating loss carryforwards can only be used to offset
80% of taxable income in any given tax year. In addition, the Company’s net operating loss carryforwards may be subject to limitation due to ownership changes.

The  Company  acquired  MacroChem  Corporation  on  March  25,  2009  and  Somanta  Pharmaceuticals,  Inc.  on  January  4,  2008.  Both  of  these  corporations  were  loss-making
entities at the time of acquisition. As a result, the net operating losses related to those acquisitions may be subject to annual limitations.

NOTE 16 – COMMITMENTS AND CONTINGENCIES

Litigation

The Company recognizes a liability for a contingency when it is probable that liability has been incurred and when the amount of loss can be reasonably estimated. When a
range of probable loss can be estimated, the Company accrues the most likely amount of such loss, and if such amount is not determinable, then the Company accrues the
minimum of the range of probable loss. As of December 31, 2022 and 2021, there was no litigation against the Company.

ARTICLE II.

Stockholders Meetings

1. Annual Meetings. Unless otherwise determined by the board of directors, the annual meeting of the stockholders of the Corporation shall be held at a reasonable hour on the
second Wednesday  of  May  unless  that  day  be  a  holiday,  in  which  case  said  meeting  shall  be  held  on  the  next  business  day  following  that  day. The  annual  meeting  of  the
stockholders shall be held for the purpose of electing directors and transacting such other corporate business as may come before the meeting.

2. Special Meetings. Special meetings of the stockholders of the Corporation may be called at any time by the chairman of the board of directors, if any, by the president or by
resolution of the board of directors. The notice or call of a special meeting shall state the purpose or purposes for which the meeting is called.

3. Place of Meeting. The annual meeting of the stockholders of the Corporation may be held at any place, either within or without the State of Delaware, as may be designated
by the board of directors. Except as limited by the following sentence, the person or persons calling any special meeting of the stockholders may designate any place, within or

4. Notice of Meeting. Except as otherwise provided in these Bylaws or by the laws of the State of Delaware, written or printed notice stating the place, date and hour of the
meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered either personally or by mail to each stockholder of
record entitled to vote at such meeting not less than ten (10) nor more than sixty (60) days before the date of the meeting. If mailed, such notice shall be deemed to be delivered
when deposited in the United States mail, postage prepaid, directed to the stockholder at his address as it appears on the records of the Corporation. An affidavit of the secretary,
assistant secretary, if any, or transfer agent of the Corporation that notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
5. Waiver of Notice. Any stockholder, either before, at, or after any stockholders’ meeting, may waive notice of the meeting, and his waiver shall be deemed the equivalent of
giving notice. Attendance at a stockholders’ meeting, either in person or by proxy, by a person entitled to notice thereof shall constitute a waiver of notice of the meeting unless
he attends for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business on the ground that the meeting was not lawfully called or
convened.

6. Fixing of Record Date. For the purpose of determining stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, to express
consent to corporate action in writing without a meeting, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise
any  rights  in  respect  of  any  change,  conversion  or  exchange  of  stock,  or  for  the  purpose  of  any  other  lawful  action,  the  board  of  directors  of  the  Corporation  may  fix,  in
advance, a record date, which shall not be more than sixty (60) nor less than ten (10) days before the date of the meeting; not more than ten (10) days after the record date for
determining shareholders entitled to express consent is fixed; and not more than sixty (60) days prior to the date of any other action. If no record date is fixed: (i) the record date
for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be the close of business on the day next preceding the day on which notice is
given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting was held; (ii) the record date for determining stockholders entitled
to express consent to corporate action in writing without a meeting, when no prior action by the board of directors is necessary, shall be the day on which the first written
consent  is  delivered  to  the  Corporation  at  its  principal  place  of  business  or  such  other  place  as  designated  by  the  boards  of  directors;  (iii)  the  record  date  for  determining
stockholders  for  any  other  purpose  shall  be  at  the  close  of  business  on  the  day  on  which  the  board  of  directors  adopts  the  resolution  relating  thereto. A  determination  of
stockholders entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting, provided, however, that the board of directors may fix a
new record date for the adjourned meeting.

7. Voting List. The officer or agent who has charge of the stock ledger of the Corporation shall prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, or any adjournment thereof, arranged in alphabetical order, showing the address of and the number of shares
registered in the name of each stockholder. Such list shall be open to the examination of any stockholder for any purpose germane to the meeting, during ordinary business
hours, for a period of at least ten (10) days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of
the meeting or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole
time thereof, and may be inspected by any stockholder who is present. The stock ledger shall be the only evidence as to who are the stockholders entitled to examine the stock
ledger, the books of the Corporation or to vote in person or by proxy at any meeting of stockholders.

8. Polls. The date and time of the opening and closing of the polls for each matter upon which the stockholders will vote at a meeting shall be announced at the meeting. No
ballot, proxies or votes, nor any revocations thereof or changes thereto, shall be accepted by the inspectors after the closing of the polls unless the Court of Chancery upon
application by a stockholder shall determine otherwise.

9. Proxies. Any stockholder entitled to vote at a meeting of the stockholders, or to express consent or dissent to corporate action in writing without meeting may authorize
another person or persons to act for him by proxy. No proxy shall be voted or acted upon after three (3) years from the date of its execution unless the proxy expressly provides
for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to
support  an  irrevocable  power. A  proxy  may  be  irrevocable  regardless  of  whether  the  interest  with  which  it  is  coupled  is  an  interest  in  the  stock  itself  or  an  interest  in  the
Corporation generally.

Without limiting the manner in which a stockholder may authorize another person or persons to act for him by proxy, the following shall constitute a valid means by which a
stockholder may grant such authority.

A stockholder may execute a writing authorizing another person or persons to act for him as proxy. Execution may be accomplished by the stockholder or his authorized officer,
director,  employee  or  agent  signing  such  writing  or  causing  his  signature  to  be  affixed  to  such  writing  by  any  reasonable  means  including  but  not  limited  to,  by  facsimile
signature.

 
 
 
 
 
 
 
 
 
 
A  stockholder  may  authorize  another  person  or  persons  to  act  for  him  as  proxy  by  transmitting  or  authorizing  the  transmission  of  a  telegram,  cablegram  or  other  means  of
electronic transmission to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization or like agent duly authorized by the
person who will be the holder of the proxy to receive such transmission, provided that any such telegram, cablegram or other electronic transmission must either set forth or be
submitted with information from which it can be determined that the telegram, cablegram or other electronic transmission was authorized by the stockholder. If it is determined
that  such  telegrams,  cablegrams  or  other  electronic  transmission  are  valid,  the  inspectors  or,  if  there  are  no  inspectors,  such  other  persons  making  that  determination  shall
specify the information upon which they relied.

Any copy facsimile telecommunication or other reliable reproduction of the writing or transmission created pursuant to this Paragraph 9 may be substituted or used in lieu of
the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication
or other reproduction shall be a complete reproduction of the entire original writing or transmission.

10. Voting Rights. Each outstanding share, regardless of class, shall be entitled to one vote, and each fractional share shall be entitled to a corresponding fractional vote on each
matter submitted to a vote at a meeting of stockholders except to the extent that the voting rights of the shares of any class or classes are limited or denied by the Certificate of
Incorporation.

Persons holding stock in a fiduciary capacity shall be entitled to vote the shares so held. Persons whose stock is pledged shall be entitled to vote, unless in the transfer by the
pledgor on the books of the Corporation he has expressly empowered the pledgee to vote thereon, in which case only the pledgee, or his proxy, may represent such stock and
vote thereon.

The Corporation’s own capital stock belonging to the Corporation or to another corporation, if a majority of the shares entitled to vote in the election or directors of such other
corporation is held, directly or indirectly, by the Corporation, shall neither be entitled to vote nor be counted for quorum purposes. Nothing in this section shall be construed as
limiting the right of the Corporation to vote stock, including but not limited to its own stock, held by it in a fiduciary capacity.

Shares which have been called for redemption shall not be deemed to be outstanding shares for the purpose of voting or determining the total number of shares entitled to vote
on any matter on and after the date on which written notice of redemption has been sent to holders thereof and a sum sufficient to redeem such shares has been irrevocably
deposited or set aside to pay the redemption price to the holders of the shares upon surrender of certificates there for.

If shares or other securities having voting power stand of record in the names of two (2) or more persons, whether fiduciaries, members of a partnership, joint tenants, tenants in
common,  tenants  by  the  entirety  or  otherwise,  or  if  two  (2)  or  more  persons  have  the  same  fiduciary  relationship  respecting  the  same  shares,  unless  the  secretary  of  the
Corporation is given written notice to the contrary and is furnished with a copy of the instrument or order appointing them or creating the relationship wherein it is so provided,
their acts with respect to voting shall have the following effect: (i) if only one (1) votes, his act binds all; (ii) if more than one (1) votes, the act of the majority so voting binds
all; (iii) if more than one (1) votes, but the vote is evenly split on any particular matter each faction may vote the securities in question proportionally, or any person voting the
shares, or a beneficiary, if any, may apply to the Court of Chancery or such other court as may have jurisdiction to appoint an additional person to act with the persons so voting
the shares, which shall then be voted as determined by a majority of such persons and the person appointed by the Court. If the instrument so filed shows that any such tenancy
is held in unequal interests, a majority or even split for the purpose of this subsection shall be a majority or even split in interest.

11. Inspectors or Election. Prior to holding any meeting of stockholders, the Corporation shall appoint one or more inspectors to act at the meeting and make a written report
thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a
meeting of stockholders, the person presiding at the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of his
duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his ability.

 
 
 
 
 
 
 
 
 
 
 
The inspectors shall (i) ascertain the number of shares outstanding and the voting power of each; (ii) determine the shares represented at a meeting and the validity of proxies
and ballots; (iii) count all votes and ballots: (iv) determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the
inspectors, and (v) certify their determination of the number of shares represented at the meeting and their count of all votes and ballots. The inspectors may appoint or retain
other persons or entities to assist the inspectors in the performance of the duties of the inspectors.

In determining the validity and counting of proxies and ballots, the inspectors shall be limited to an examination of the proxies, any envelopes submitted with those proxies, any
information  provided  in  accordance  with  Article  II,  Paragraph  9  of  these  Bylaws,  any  records  of  the  Corporation,  except  that  the  inspectors  may  consider  other  reliable
information for the limited purpose of reconciling proxies and ballots submitted by or on behalf of banks, brokers, their nominees or similar persons which represent more votes
than the holder of a proxy is authorized by the record owner to cast or more votes than the stockholder holds of record. If the inspectors consider other reliable information for
the limited purpose permitted herein, the inspectors at the time they make their certification shall specify the precise information considered by them including the person or
persons from whom they obtained the information, when the information was obtained, the means by which the information was obtained and the basis for the inspectors’ belief
that such information is accurate and reliable.

12. Quorum. Except as otherwise provided in the Certificate of Incorporation, the presence, in person or by proxy, of the holders of one-third of the shares outstanding and
entitled to vote shall constitute a quorum at meetings of the stockholders. In all matters, other than the election of directors, the affirmative vote of a majority of the shares
present in person or represented by proxy at the meeting and actually voting on the subject matter shall be the act of the stockholders. Directors shall be elected by a majority of
the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. In the event any stockholders withdraw from a
duly organized meeting at which a quorum was initially present, the remaining shares represented shall constitute a quorum for the purpose of continuing to do business, and
the affirmative vote of the majority of the remaining shares represented at the meeting and entitled to vote on the subject matter shall be the act of the stockholders unless the
vote of a greater number or voting by classes is required by the General Corporation Law of Delaware or the Certificate of Incorporation.

13. Election of Directors. Except as provided in Article III, Section 2, of these Bylaws with respect to the filling of vacancies that occur from time to time on the Board of
Directors, a nominee for director shall be elected to the Board of Directors by the vote of the majority of the votes cast by stockholders with respect to that director’s election at
any meeting of stockholders for the election of directors. For purposes of this Section 13, a majority of votes cast shall mean that the number of shares voted “for” a director’s
election exceeds fifty percent (50%) of the number of votes cast with respect to that director’s election. Votes cast shall include a stockholder’s direction to withhold authority
in each case and shall exclude abstentions with respect to that director’s election. Notwithstanding the foregoing, directors shall be elected by a plurality of the votes cast (and
not by majority vote) at any meeting of stockholders where the election of directors is a Contested Election (as defined below). For purposes of these Bylaws, an election of
directors shall be considered a “Contested Election” if (i) the number of nominees standing for election at any meeting of stockholders exceeds the number of directors to be
elected  at  such  meeting,  with  the  determination  that  an  election  is  “contested”  to  be  made  by  the  Secretary  of  the  Corporation  based  on  whether  one  or  more  notices  of
nomination, purporting to be in compliance with Article VII, Section C the Certificate of Incorporation, were received by the Secretary of the Corporation (provided that the
determination that an election is a “Contested Election” shall not prejudice the ability of the Corporation to challenge whether a notice of nomination has been submitted in
accordance with Article VII, Section C the Certificate of Incorporation, as applicable), and (ii) such notice of nomination or notices of nomination have not been withdrawn on
or prior to the tenth (10th) calendar day preceding the date the Corporation files with the Securities and Exchange Commission (“SEC”) its initial definitive proxy statement
relating to such meeting of stockholders such that the number of candidates for election as director no longer exceeds the number of directors to be elected at such meeting
(regardless of whether or not such proxy statement is thereafter revised or supplemented). If directors are to be elected by a plurality of the votes cast, stockholders shall not be
permitted to vote against a nominee.

 
 
 
 
 
 
 
Each  person  who  is  nominated  to  stand  for  election  as  director,  whether  such  nomination  is  proposed  by  the  Corporation  or  a  stockholder,  shall,  as  a  condition  to  such
nomination, tender an irrevocable and executed letter of resignation in advance of the meeting for the election of directors. If a nominee for director is not elected and the
nominee  is  an  incumbent  director,  the  Board’s  Nominating  and  Corporate  Governance  Committee  (the  “Nominating  and  Corporate  Governance  Committee”)  will  make  a
recommendation to the Board as to whether to accept or reject the tendered resignation, or whether other action should be taken. The Board will act on the tendered resignation,
taking into account the Nominating and Corporate Governance Committee’s recommendation, and make public disclosure of its decision regarding the tendered resignation and
the  rationale  behind  the  decision  within  ninety  (90)  calendar  days  from  the  date  of  the  certification  of  the  election  results.  The  Nominating  and  Corporate  Governance
Committee,  in  making  its  recommendation,  and  the  Board,  in  making  its  decision,  may  each  consider  any  factors  or  other  information  that  they  consider  appropriate  and
relevant. The director who tenders his or her resignation will not participate in the recommendation of the Nominating and Corporate Governance Committee or the decision of
the Board with respect to his or her tender of resignation, but may participate in the recommendation or the decision regarding another director’s tender of resignation.

14. Adjournments. If less than a quorum of the outstanding shares entitled to vote is represented at any meeting of the stockholders, a majority of the shares so represented may
adjourn  the  meeting  from  time  to  time  for  a  period  not  to  exceed  thirty  (30)  days  at  any  one  adjournment,  without  further  notice,  provided  the  time  and  place  thereof  are
announced at the meeting at which the adjournment is taken. At the adjourned meeting, the Corporation may transact any business which might have been transacted at the
original meeting. Any meeting of the stockholders may adjourn from time to time until its business is completed. If the adjournment is for more than thirty (30) days, or if after
the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the
meeting.

15. Informal Act by Shareholders. Any action required to be taken at a meeting of shareholders, or any action which may be taken at a meeting of shareholders, may be taken
without a meeting, without prior notice and without a vote, if a consent or consents in writing setting forth the action so taken, shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were
present and voted shall be delivered to the Corporation by said consent or consents delivered at its principal place of business or such other place as designated by the board of
directors. Delivery made to the Corporation shall be by hand or by certified or registered mail, return receipt requested.

ARTICLE III.

Board of Directors

1. Number, Qualifications and Term of Office. Except as otherwise provided in the Certificate of Incorporation or the General Corporation Law of Delaware, the business and
affairs of the Corporation shall be managed under the direction of a board of directors consisting of from three to fifteen members. Each director shall be a natural person of the
age of fifteen years or older, but does not need to be a resident of the state of Delaware or a stockholder of the Corporation. The board of directors, by resolution, may increase
or  decrease  the  number  of  directors  from  time  to  time.  Except  as  otherwise  provided  in  these  Bylaws  or  in  the  Certificate  of  Incorporation,  the  board  of  directors  shall  be
divided into three (3) classes as nearly equal in number as possible. Each director in each class shall be elected at the appropriate annual meeting of stockholders, as determined
by the Certificate of Incorporation, and shall hold office for a term of three (3) years and until his successor is elected and qualified or until his earlier resignation or removal.
No decrease in the number of directors shall have the effect of shortening the term of any incumbent director.

2. Vacancies and Newly Created Directorships. Vacancies and newly created directorships resulting from any increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class shall be filled solely by a majority of the directors then in office, although less than a quorum, or by a sole remaining
director. Any directors so chosen shall hold office until the next election of the class for which such director shall have been chosen, and until their successors shall be elected
and qualified. No decrease in the number of directors constituting the board of directors shall shorten the term of any incumbent director.

If at any time of filling any vacancy or newly created directorship, the directors then in office shall constitute less than a majority of the whole board, the Court of Chancery
may, upon application of any stockholder or stockholders holding at least ten percent (10%) of the total number of shares at the time outstanding having the right to vote for
such directors, summarily order an election to be held to fill any such vacancies or newly created directorships, or to replace the directors chosen by the directors then in office
as aforesaid, which election shall be governed by Section 211 of the General Corporation Law of Delaware.

 
 
 
 
 
 
 
 
 
 
 
Any director may resign at any time by giving written notice to the president or to the secretary of the Corporation. Such resignation shall take effect at the future time specified
therein; and unless otherwise specified therein, the acceptance of such resignation shall not be necessary to make it effective. Any vacancy occurring on the board of directors
created by the resignation of a director, may be filled by the affirmative vote of a majority of directors then in office, including those who have so resigned. The vote thereon
shall take effect when such resignation or resignations shall become effective. A director elected to fill a vacancy shall be elected for the unexpired term of his predecessor in
office.

3. Removal. Any director or the entire board of directors may be removed in accordance with the provisions of Article VII Subparagraph D of the Certificate of Incorporation.

4. Compensation. Any director may be paid any one or more of the following: his expenses, if any, of attendance at meetings; a fixed sum for attendance at each meeting; or a
stated salary as director. No such payment shall preclude any director from serving the Corporation in any other capacity and receiving compensation therefor. A director shall
also be entitled to receive options for the acquisition of shares of stock of the corporation.

ARTICLE IV.

Meetings of the Board

1. Place of Meetings. The regular or special meetings of the board of directors or any committee designated by the board may be held at the principal office of the Corporation
or at any other place within or without the State of Delaware that a majority of the board of directors or any such committee, as the case may be, may designate from time to
time by resolution.

2. Regular Meetings. The board of directors shall meet each year immediately after the annual meeting of the stockholders for the purpose of electing officers and transacting
such other business as may come before the meeting. The board of directors or any committee designated by the board may provide, by resolution, for the holding of additional
regular meetings without other notice than such resolution.

3. Special Meetings. Special meetings of the board of directors or any committee designated by the board may be called at any time by the chairman of the board, if any, by the
president or by a majority of the members of the board of directors or any such committee, as the case may be.

4. Notice of Meetings. Notice of the regular meetings of the board of directors or any committee designated by the board need not be given. Except as otherwise provided by
these Bylaws or the laws of the State of Delaware, written notice of each special meeting of the board of directors or any such committee setting forth the time and the place of
the  meeting  shall  be  given  to  each  director  not  less  than  two  (2)  days  prior  to  the  time  fixed  for  the  meeting.  Notice  of  special  meetings  may  be  either  given  personally,
personally by telephone, or by sending a copy of the notice through the United States mail or by telegram, telex or telecopy, charges prepaid, to the address of each director
appearing on the books of the Corporation. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail so addressed, with postage prepaid
thereon. If notice is given by telegram, telex or telecopy, such notice shall be deemed to be delivered when the telegram is delivered to the telegraph, telex or telecopy operator.
Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the board of directors need be specified in the notice or waiver of notice of such
meeting.

5. Waiver of Notice. A director may in writing waive notice of any special meeting of the board of directors or any committee, either before, at, or after the meeting; and his
waiver shall be deemed the equivalent of giving notice. Attendance of a director at a meeting shall constitute waiver of notice of that meeting unless he attends for the express
purpose of objecting to the transaction of business because the meeting has not been lawfully called or convened.

 
 
 
 
 
 
 
 
 
 
 
 
 
6. Quorum. At meetings of the board of directors or any committee designated by the board a majority of the number of directors fixed by these Bylaws or a majority of the
members of any such committee, as the case may be, shall be necessary to constitute a quorum for the transaction of business. If a quorum is present, the act of the majority of
directors in attendance shall be the act of the board of directors or any such committee, as the case may be, unless the act of a greater number is required by these Bylaws, the
Certificate  of  Incorporation  or  the  General  Corporation  Law  of  Delaware.  One  or  more  directors  may  participate  in  meetings  of  the  board  of  directors  as  authorized  by
Subparagraph 11 of this Article IV by conference telephone, while the remaining director or directors are physically present at the meeting.

7. Presumption of Assent. A director who is present at a meeting of the board or committee designated by the board when corporate action is taken is deemed to have assented
to the action taken unless: (i) he objects at the beginning of such meeting to the holding of the meeting or the transacting of business at the meeting; (ii) he contemporaneously
requests that his dissent from the action taken be entered in the minutes of such meeting; or (iii) he gives written notice of his dissent to the presiding officer of such meeting
before its adjournment or to the secretary of the Corporation immediately after adjournment of such meeting. The right of dissent as to a specific action taken in a meeting of a
board or committee thereof is not available to a director who votes in favor of such action.

8. Reliance on Books of Account or Reports. Any member of the board of directors or any committee designated by the board of directors shall, in the performance of his
duties, be fully protected in relying in good faith upon the records of the Corporation and upon such information, opinions, reports or statements presented to the Corporation
by any of its officers, or employees, or committees of the board of directors, or by any other person as to matters the members reasonably believes are within such other persons
professional or expert competence and who has been selected with reasonable care by or on behalf of the Corporation, or in relying in good faith upon other records of the
Corporation.

9. Committees. The board of directors may, by a resolution passed by a majority of the whole board designate one (1) or more committees, each committee to consist of one (1)
or  more  directors  of  the  corporation.  The  board  may  designate  one  or  more  directors  as  alternate  members  of  any  committee  who  may  replace  any  absent  or  disqualified
member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members present at any meeting and not disqualified
from voting, whether or not he or they constitute a quorum, may unanimously appoint another member of the board of directors to act at the meeting in the place of any such
absent or disqualified member.

Any such committee to the extent provided in the resolution of the board of directors shall have and may exercise all of the powers and authority of the board of directors in the
management of the business and affairs of the Corporation and may authorize the seal of the Corporation to be affixed to all papers which it may acquire. No such committee
shall have the power or authority of the board of directors to: (i) amend the Certificate of Incorporation; (ii) adopt an agreement of merger or consolidation; (iii) recommend to
the  stockholders  the  sale,  lease  or  exchange  of  all  or  substantially  all  of  the  Corporation’s  property  and  assets;  (iv)  recommend  to  the  stockholders  a  dissolution  of  the
Corporation or a revocation of a dissolution; (v) amend the Bylaws of the Corporation; (vi) or unless expressly provided for by resolution, or in the Certificate of Incorporation,
declare a dividend, authorize the issuance of stock or to adopt a certificate of ownership and merger. To the extent authorized by resolution or resolutions providing for the
issuance  of  shares  of  stock,  adopted  by  the  board,  a  committee  may:  (i)  fix  the  designations  and  any  of  the  preferences  or  rights  of  such  shares  relating  to  dividends,
redemption, dissolution, any distribution of assets of the Corporation or the conversion into, or the exchange of such shares for, shares of any other class or classes or any other
series of the same or any other class or classes of stock of the Corporation; or (ii) fix the number of shares of any series of stock or authorize the increase or decrease of the
shares of any series. If any such delegation of the authority of the board of directors is made as provided herein, all references to the board of directors contained in these
Bylaws, the Certificate of Incorporation, the General Corporation Law of Delaware or any other applicable law or regulation relating to the authority so delegated shall be
deemed to refer to such committee.

10. Informal Action by Directors. Any action required or permitted to be taken at a meeting of the board of directors or any committee thereof, may be taken without a meeting
if all the members of the board or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the board or
committee.  Such  consent  shall  have  the  same  force  and  effect  as  a  unanimous  vote  of  the  directors  and  may  be  stated  as  such  in  any  articles  or  documents  filed  with  the
Secretary of State of Delaware under the General Corporation Law of Delaware.

11. Telephonic Meetings. Members of the board of directors or any committee designated by the board may participate in meeting of such board or committee by means of a
conference  telephone  or  similar  communications  equipment  by  which  all  persons  participating  in  the  meeting  can  hear  each  other  at  the  same  time.  Participation  in  such  a
meeting shall constitute presence in person at the meeting.

 
 
 
 
 
 
 
 
 
 
ARTICLE V.

Officers and Agents

1. General. The executive officers of the Corporation shall be elected annually by the board of directors at the first meeting of the board held after each annual meeting of the
stockholders. If the election of such officers shall not be held at such meeting, such election shall take place as soon thereafter as a meeting may conveniently be held. The
officers of the Corporation shall consist of a president, a secretary and a treasurer, or a secretary/treasurer; in addition, one or more vice presidents, a chairman of the board of
directors and such other officers, assistant officers, agents and employees that the board of directors may from time to time deem necessary may be elected by the board of
directors or be appointed in a manner prescribed by the board.

Two or more offices may be held by the same person. Officers shall hold office until their successors are elected and qualified, unless they are sooner removed from office as
provided in these Bylaws. All officers of the Corporation shall be natural persons of the age of eighteen years or older. Officers of the Corporation need not be residents of the
State of Delaware or directors or stockholders of the Corporation.

2.  General  Duties. All  officers  and  agents  of  the  Corporation,  as  between  themselves  and  the  Corporation,  shall  have  such  authority  and  shall  perform  such  duties  in  the
management of the Corporation as may be provided in these Bylaws or as may be determined by resolution of the board of directors not inconsistent with these Bylaws. In all
cases where the duties of any officer, agent or employee are not prescribed by the Bylaws or by the board of directors, such officer, agent or employee shall follow the orders
and instructions of the president.

Any officer shall have the power to execute and deliver on behalf of and in the name of the Corporation any instrument requiring the signature of an officer of the Corporation,
except as otherwise provided in these Bylaws or where the execution and delivery thereof shall be expressly delegated by the board of directors to some other officer or agent of
the  Corporation.  Unless  authorized  to  do  so  by  these  Bylaws  or  by  the  board  of  directors,  no  officer,  agent  or  employee  shall  have  any  power  or  authority  to  bind  the
Corporation in any way, to pledge its credit or to render it liable pecuniarily for any purpose or in any amount.

3. Vacancies. When a vacancy occurs in one of the executive offices by reason of death, resignation or otherwise, it shall be filled by a resolution of the board of directors. The
officer so selected shall hold office until his successor is chosen and qualified.

4. Salaries. The board of directors shall fix the salaries of the officers of the Corporation. The salaries of other agents and employees of the Corporation may be fixed by the
board of directors, or by any committee designated by the board or by an officer to whom that function has been delegated by the board. No officer shall be prevented from
receiving such salary by reason of the fact that he is also a director of the Corporation.

5. Removal. Any officer or agent of this Corporation may be removed by the board of directors whenever in its judgment the best interests of the Corporation may be served
thereby, but such removal shall be without prejudice to the contract rights, if any, of the person so removed. Election or appointment of an officer or an agent shall not of itself
create contract rights.

6. Chairman of the Board. The chairman of the board, if any, shall preside as chairman at meetings of the stockholders and the board of directors. He shall, in addition, have
such other duties as the board may prescribe that he perform. At the request of the president, the chairman of the board may, in the case of the president’s absence or inability to
act, temporarily act in his place. In the case of death of the president or in the case of his absence or inability to act without having designated the chairman of the board to act
temporarily in his place, the chairman of the board shall perform the duties of the president, unless the board of directors, by resolution, provides otherwise. If the chairman of
the board shall be unable to act in place of the president, any vice president may exercise such powers and perform such duties as provided in section 8 below.

 
 
 
 
 
 
 
 
 
 
 
 
 
6a. Executive Chairman. The board of directors may from time to time elect or appoint the chairman of the board, if any, to serve as executive chairman. To the extent such
position is filled, the executive chairman shall be an executive officer of the Corporation who reports to the board of directors. The executive chairman shall have such powers
and duties as the board of directors shall designate from time to time.

6b.  Chief  Executive  Officer.  The  board  of  directors  shall  appoint  a  chief  executive  officer,  who  shall  be  the  Corporation’s  principal  executive  officer. All  other  executive
officers, other than the executive chairman, shall report to the chief executive officer. The chief executive officer shall have general and active management and supervision of
the business and affairs of the Corporation.

7. President. The president shall be the chief executive officer of the Corporation (unless the board of directors appoints another executive to be the chief executive officer of
the Corporation with such duties and responsibilities as the board of directors shall delegate from time to time), and, subject to the control of the board of directors, shall have
general supervision of the business and affairs of the Corporation. In the event the position of chairman of the board shall not be occupied or the chairman shall be absent or
otherwise unable to act, the president shall preside at meetings of the stockholders and directors and shall discharge the duties of the presiding officer. At each annual meeting
of  the  stockholders  the  president  shall  give  a  report  of  the  business  of  the  Corporation  for  the  preceding  fiscal  year  and  shall  perform  whatever  other  duties  the  board  of
directors  may  from  time  to  time  prescribe. The  president  may  sign,  with  the  secretary  or  any  other  proper  officer  of  the  Corporation  thereunto  authorized  by  the  board  of
directors, certificates for shares of the Corporation, any deeds, mortgages, bonds, contracts, or other instruments which the board of directors has authorized to be executed,
except  in  cases  where  the  signing  and  execution  thereof  shall  be  expressly  delegated  by  the  board  of  directors  or  by  these  Bylaws  to  some  other  officer  or  agent  of  the
Corporation, or shall be required by law to be otherwise signed or executed.

8. Vice Presidents. Each vice president shall have such powers and perform such duties as the board of directors may from time to time prescribe or as the president may from
time to time delegate to him. At the request of the president, in the case of the president’s absence or inability to act, any vice president may temporarily act in his place. In the
case of the death of the president, or in the case of his absence or inability to act without having designated a vice president or vice presidents to act temporarily in his place, the
board of directors, by resolution, may designate a vice president or vice presidents, to perform the duties of the president. If no such designation shall be made, the chairman of
the  board  of  directors,  if  any,  shall  exercise  such  powers  and  perform  such  duties,  as  provided  in  Section  6  above,  but  if  the  Corporation  has  no  chairman  of  the  board  of
directors, or if the chairman is unable to act in place of the president, all the vice presidents may exercise such powers and perform such duties.

9. Secretary. The secretary shall keep or cause to be kept in books provided for that purpose the minutes of the meetings of the stockholders, executive committee, if any, and
any other committees, and of the board of directors; shall see that all notices are duly given in accordance with the provisions of these Bylaws and as required by law; shall be
custodian of the records and of the seal of the Corporation and see that the seal is affixed to all documents, the execution of which on behalf of the Corporation under its seal is
duly authorized and in accordance with the provisions of these Bylaws; keep a register of the post office address of each stockholder which shall be furnished to the secretary
by such stockholder, sign with the president certificates for shares of the Corporation, the issuance of which shall have been authorized by resolution of the board of directors;
have a general charge of the stock transfer books of the Corporation; and, in general, shall perform all duties incident to the office of secretary and such other duties as may,
from time to time, be assigned to him by the board of directors or by the president. In the absence of the secretary or his inability to act, the assistant secretaries, if any, shall act
with the same powers and shall be subject to the same restrictions as are applicable to the secretary.

 
 
 
 
 
 
 
 
10. Treasurer. The treasurer shall have custody of corporate funds and securities. He shall keep full and accurate accounts of receipts and disbursements and shall deposit all
corporate  monies  and  other  valuable  effects  in  the  name  and  to  the  credit  of  the  Corporation  in  the  depository  or  depositories  of  the  Corporation  selected  by  the  board  of
directors,  and  shall  render  an  account  of  his  transactions  as  treasurer  and  of  the  financial  condition  of  the  Corporation  to  the  president  and/or  the  board  of  directors  upon
request. Such power given to the treasurer to deposit and disburse funds shall not, however, preclude any other officer or employee of the Corporation from also depositing and
disbursing funds when authorized to do so by the board of directors. The treasurer shall, if required by the board of directors, give the Corporation a bond in such amount and
with such surety or sureties as may be ordered by the board of directors for the faithful performance of duties of his office. The treasurer shall have such other duties as may be
from time to time prescribed by the board of directors or the president. In the absence of the treasurer or his inability to act, the assistant treasurers, if any, shall act with the
same authority and shall be subject to the same restrictions as are applicable to the treasurer.

11. Delegation of Duties. Whenever an officer is absent, or whenever, for any reason, the board of directors may deem it desirable, the board may delegate the powers and
duties of an officer to any other officer or officers or to any director or directors.

12. Bond of Officers. The board of directors may require any officer to give the Corporation a bond in such sum and with such surety or sureties as shall be satisfactory to the
board  of  directors  for  such  terms  and  conditions  as  the  board  of  directors  may  specify,  including  without  limitation  for  the  faithful  performance  of  his  duties  and  for  the
restoration to the Corporation of all property in his possession or under his control belong to the Corporation.

13.  Loans to Director, Officers, Employees. The Corporation may lend money to, guarantee the obligations of and otherwise assist directors, officers and employees of the

ARTICLE VI.

Stock Certificates and the Transfer of Shares

1.  Stock  Certificates;  Uncertificated  Shares. The  shares  of  the  Corporation  shall  be  represented  by  certificates,  provided  that  the  board  of  directors  of  the  Corporation  may
provide  by  resolution  or  resolutions  that  some  or  all  of  any  or  all  classes  or  series  of  its  stock  shall  be  uncertificated  shares. Any  such  resolution  shall  not  apply  to  shares
represented by a certificate until such certificate is surrendered to the corporation. Notwithstanding the adoption of such a resolution by the board of directors, every holder of
stock represented by certificates and upon request every holder of uncertificated shares shall be entitled to have a certificate signed by, or in the name of the Corporation by the
chairman or vice-chairman of the board of directors, or the president or vice-president, and by the treasurer or an assistant treasurer, or the secretary or an assistant secretary of
the Corporation representing the number of shares registered in certificate form. Any or all the signatures on the certificate may be a facsimile. In case any officer, transfer
agent or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent or registrar before such
certificate is issued, it may be issued by the Corporation with the same effect as if he were such officer, transfer agent or registrar at the date of issue.

2.  Consideration  for  Shares.  Shares  shall  be  issued  for  such  consideration  as  shall  be  fixed  from  time  to  time  by  the  board  of  directors.  Consideration  for  shares  shall  be
expressed in dollars, and shall not be less than the par value or stated value therefor, as the case may be. The par value for shares, if any, shall be stated in the Certificate of
Incorporation, and the stated value for shares, if any, shall be fixed from time to time by the board of directors. Treasury shares may be disposed of by the Corporation for such
consideration expressed in dollars as may be fixed from time to time by the board. Consideration for shares may consist, in whole or in part, of money, other property whether
tangible, intangible or both, or in labor or services actually performed for the Corporation, but the promise of future services of a subscriber or direct purchaser of shares from
the Corporation shall not constitute payment or part payment for shares.

3. Lost Certificates. The board of directors may direct a new certificate of stock or uncertificated share in place of any certificate issued by it, alleged to have been lost, stolen or
destroyed if the owner makes an affidavit or affirmation of that fact and produces such evidence of loss or destruction as the board may require. The board, in its discretion,
may as a condition precedent to the issuance of a new certificate require the owner to give the Corporation a bond sufficient to indemnify it against any claim that may be made
against the Corporation on account of the alleged loss, theft or destruction of the certificate or the issuance of such new certificate.

 
 
 
 
 
 
 
 
 
 
 
 
4.  Transfer  of  Shares.  Shares  of  the  Corporation  shall  only  be  transferred  on  its  books  upon  the  surrender  to  the  Corporation  of  the  share  certificates  duly  endorsed  or
accompanied by proper evidence of succession, assignment or authority to transfer and such documentary stamps as may be required by law. In that event, the surrendered
certificates shall be cancelled, new certificates issued to the persons entitled to them, and the transaction recorded on the books or the Corporation.

5.  Registered  Stockholders. The  Corporation  shall  be  entitled  to  treat  the  holder  of  record  of  shares  as  the  holder  in  fact  and,  except  as  otherwise  provided  by  the  laws  of
Delaware, shall not be bound to recognize any equitable or other claim to or interest in the shares.

The board of directors may adopt by resolution a procedure whereby a stockholder may certify in writing to the Corporation that all or a portion of the shares registered in the
name of such stockholder are held for the account of a specified person or persons. Such resolution shall set forth: (i) the classification of stockholder who may certify; (ii) the
purpose or purposes for which the certification may be made; (iii) the form of certification and information to be contained therein; (iv) if the certification is with respect to a
record date or closing of the stock transfer books within which the certification must be received by the Corporation; and (v) such other provisions with respect to the procedure
as are deemed necessary or desirable.

Upon receipt by the Corporation of a certification complying with the procedure, the persons specified in the certification shall be deemed, for the purpose or purposes set forth
in the certification, to be the holders of record of the number of shares specified in place of the stockholder making the certification.

6. Stock Ledger. An appropriate stock journal and ledger shall be kept by the secretary or such registrars or transfer agents as the directors by resolution may appoint in which
all transactions in the shares of stock of the Corporation shall be recorded.

7. Location. The books, accounts and records of the Corporation may be kept at such place or places within or outside the State of Delaware as the board of directors may from
time to time determine.

8. Inspection. The books, accounts and records of the Corporation shall be open for inspection by any member of the board of directors at all times, and open to inspection by
the stockholders at such times, and subject to such regulations as the board of directors may prescribe, except as otherwise provided by statute.

ARTICLE VII.

Seal and Fiscal Year

1. Seal. The Corporation shall have a seal in the form impressed to the left of this paragraph of the Bylaws.

2. Fiscal Year. The fiscal year of the Corporation shall be determined by the board of directors and set forth in the minutes of the directors. Said fiscal year may be changed
from time to time by the board of directors in its discretion.

ARTICLE VIII.

Dividends

Dividends shall be declared and paid out of the surplus or net profits for the fiscal year in which the dividend is declared, and/or the preceding fiscal year as often and at such
times  as  the  board  of  directors  may  determine.  If  the  capital  of  the  Corporation,  computed  in  accordance  with  the  General  Corporation  Law  of  Delaware,  shall  have  been
diminished by depreciation in the value of its property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and
outstanding stock; the board of directors shall not declare and pay out of net profits any dividends upon any shares of its capital stock until the deficiency in the amount of
capital represented by issued and outstanding stock shall have been repaired. No unclaimed dividend shall bear interest against the Corporation.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
ARTICLE IX.

Amendments

Subject to repeal or change by action of the stockholders in accordance with the Certificate of Incorporation, the board of directors may amend, supplement or repeal these
Bylaws  or  adopt  new  Bylaws,  and  all  such  changes  shall  affect  and  be  binding  upon  the  holders  of  all  shares  heretofore  as  well  as  hereafter  authorized,  subscribed  for  or
offered.

ARTICLE X.

Miscellaneous

1. Gender. Whenever required by the context, the singular shall include the plural, the plural the singular, and one gender shall include all genders.

2.  Invalid  Provision.  The  invalidity  or  unenforceability  of  any  particular  provision  of  these  Bylaws  shall  not  affect  the  other  provisions  herein,  and  these  Bylaws  shall  be
construed in all respects as if such invalid or unenforceable provision was omitted.

3. Governing Law. These Bylaws shall be governed by and construed in accordance with the laws of the State of Delaware.

4. Severability. If any provision (or any part thereof) or provisions of these Bylaws shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any
reason whatsoever: (i) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of these Bylaws (including, without
limitation, each portion of any section of these Bylaws containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or
unenforceable) shall not in any way be affected or impaired thereby and (ii) to the fullest extent possible, the provisions of these Bylaws (including, without limitation, each
such portion containing any such provision held to be invalid, illegal or unenforceable) shall be construed for the benefit of the Corporation to the fullest extent permitted by
law  so  as  to  (a)  give  effect  to  the  intent  manifested  by  the  provision  held  invalid,  illegal  or  unenforceable,  and  (b)  permit  the  Corporation  to  protect  its  directors,  officers,
employees and agents from personal liability in respect of their good faith service. Reference herein to laws, regulations or agencies shall be deemed to include all amendments
thereof, substitutions therefor and successors thereto, as the case may be.

ARTICLE XI.

Exclusive Jurisdiction for Certain Actions

Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law,
be the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of the Corporation, (b) any action asserting a claim of breach of fiduciary duty
owed  by,  or  other  wrongdoing  by,  any  director,  officer,  employee  or  agent  of  the  Corporation  to  the  Corporation  or  the  Corporation’s  stockholders,  creditors  or  other
constituents, (c) any action asserting a claim arising pursuant to any provision of the General Corporation Law of Delaware or the Certificate of Incorporation or these Bylaws
of the Corporation, (d) any action to interpret, apply, enforce or determine the validity of the Certificate of Incorporation or these Bylaws of the Corporation or (e) any action
asserting  a  claim  governed  by  the  internal  affairs  doctrine,  in  each  case  subject  to  said  Court  of  Chancery  of  the  State  of  Delaware  having  personal  jurisdiction  over  the
indispensable parties named as defendants therein; provided that if and only if the Court of Chancery of the State of Delaware dismisses any such action for lack of subject
matter jurisdiction, such action may be brought in another state or federal court sitting in the State of Delaware.

Unless the Corporation consents in writing to the selection of an alternative forum, the federal district courts of the United States shall, to the fullest extent permitted by law, be
the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended.

To  the  fullest  extent  permitted  by  applicable  law,  any  person  or  entity  purchasing  or  otherwise  acquiring  any  interest  in  shares  of  capital  stock  of  the  Corporation  shall  be
deemed to have notice of and consented to the provisions of this Article XI of these Bylaws.
