Note Regarding Forward-Looking Statements

This  Annual  Report  on  Form  10-K  and  the  information  incorporated  herein  by  reference  contain  forward-looking  statements  that  involve  a
number of risks and uncertainties, many of which are beyond our control. Although our forward-looking statements reflect the good faith judgment of our
management, these statements can only be based on facts and factors currently known by us. Consequently, these forward-looking statements are inherently
subject  to  risks  and  uncertainties,  and  actual  results  and  outcomes  may  differ  materially  from  results  and  outcomes  discussed  in  the  forward-looking
statements as a result of various factors, including those set forth below under the caption “Risk Factors.”

Forward-looking  statements  in  this  Annual  Report  and  in  our  other  reports  with  the  Securities  and  Exchange  Commission  (the  “SEC”),  for

example, may include statements regarding:

● our ability  to  submit  our  product  candidates  through  the  505(b)(2)  regulatory  pathway  for  approval  by  the  U.S.  Food  and  Drug  Administration  (the

“FDA”);

● our ability to obtain FDA approval for our product candidates;

● our ability to comply with all U.S. and foreign regulations concerning the development, manufacture and sale of our product candidates;

● our ability to maintain, protect and enhance our intellectual property;

● costs associated with initiating and defending intellectual property infringement and other claims;

● our expectations regarding the period during which we qualify as an emerging growth company under the JOBS Act;

● future acquisitions of or investments in complementary companies or technologies; and

● our ability to comply with evolving legal standards and regulations, particularly concerning requirements for being a public company.

In  some  cases,  you  can  identify  forward-looking  statements  by  terms  such  as  “anticipates,”  “believes,”  “continue,”  “could,”  “estimates,”
“expects,” “hopes,” “intends,” “may,” “plan,” “potential,” “predicts,” “projects,” “seeks,” “should,” “will,” “would” or the negative of those terms,
and similar expressions that convey uncertainty of future events or outcomes. In addition, statements that “we believe” and similar statements reflect our
beliefs and opinions on the relevant subject. These statements include, but are not limited to, statements under the captions “Business,” “Risk Factors”
and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” as well as other sections in this Annual Report on Form
10-K. We discuss many of the risks associated with the forward-looking statements in this Annual Report on Form 10-K in greater detail under the heading
“Risk Factors.” Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for
our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors,
may  cause  actual  results  to  differ  materially  from  those  contained  in  any  forward-looking  statements  we  may  make.  You  should  be  aware  that  the
occurrence of any of the events discussed under the caption “Risk Factors” and elsewhere in this report could substantially harm our business, results of
operations and financial condition and that if any of these events occurs, the trading price of our common stock could decline and you could lose all or a
part of the value of your shares of our common stock.

The cautionary statements made in this report are intended to be applicable to all related forward-looking statements wherever they may appear
in this Annual Report on Form 10-K. We urge you not to place undue reliance on these forward-looking statements, which speak only as of the date of this
Annual Report on Form 10-K. For all forward-looking statements, we claim the protection of the safe harbor for forward-looking statements contained in
the  Private  Securities  Litigation  Reform  Act  of  1995.  Except  as  required  by  law,  we  assume  no  obligation  to  update  our  forward-looking  statements
publicly, or to update the reasons actual results could differ materially from those anticipated in any forward-looking statements, whether as a result of new
information, future events or otherwise.

This  Annual  Report  on  Form  10-K  also  contains  estimates,  projections  and  other  information  concerning  our  industry,  our  business,  and  the
markets for our product candidates, as well as data regarding market research, estimates and forecasts prepared by our management. Information that is
based  on  estimates,  forecasts,  projections,  market  research  or  similar  methodologies  is  inherently  subject  to  uncertainties,  and  actual  events  or
circumstances  may  differ  materially  from  events  and  circumstances  reflected  in  this  information.  Unless  otherwise  expressly  stated,  we  obtained  this
industry,  business,  market  and  other  data  from  reports,  research  surveys,  studies  and  similar  data  prepared  by  market  research  firms  and  other  third
parties, industry, medical and general publications, government data and similar sources. As used in this Annual Report on Form 10-K, unless the context
indicates or otherwise requires, “Eton,” “our company,” “we,” “us,” and “our” refer to Eton Pharmaceuticals, Inc., a Delaware corporation.

You should read the following together with the more detailed information regarding our company, our common stock and our financial statements
and  notes  to  those  statements  appearing  elsewhere  in  this  report  or  incorporated  by  reference.  The  SEC  allows  us  to  “incorporate  by  reference”
information that we file with the SEC, which means that we can disclose important information to you by referring you to those documents. The information
incorporated by reference is considered to be part of this report.

Item 1. Business

Overview

PART I

We  are  a  pharmaceutical  company  focused  on  developing,  acquiring,  and  commercializing  innovative  pharmaceutical  products  that  fulfill  an
unmet  patient  need.  Since  the  formation  of  our  company  in  2017,  we  have  used  our  expertise  in  business  development,  regulatory,  and  product
development to assemble a diversified portfolio of eleven products and product candidates. Six of our products have been approved by the U.S. Food &
Drug Administration (“FDA”) and commercially launched, and an additional four product candidates have been submitted to the FDA. We plan to continue
growing our business through the acquisition of additional late-stage, high-value product candidates.

Product Portfolio

Our product portfolio is comprised of three categories: Orphan Drugs, Hospital Products, and Royalty Products.

Orphan Drugs

Our orphan drug product category is focused on commercializing products that treat the unmet needs of patients suffering from rare diseases. As
defined  by  the  FDA,  orphan  drugs  typically  address  diseases  that  impact  fewer  than  200,000  patients  in  the  United  States.  Given  these  small  patient
populations,  products  are  typically  promoted  with  small,  targeted  sales  forces  and  distributed  through  high-touch  specialty  pharmacies  that  provide
comprehensive  services  to  patients  or  caregivers.  We  expect  to  continue  to  grow  our  orphan  drug  product  category.  Some  of  our  orphan  drug  products
include:

Alkindi  Sprinkle®  (hydrocortisone  granules)  -  This  product  was  approved  by  the  FDA  in  September  2020  as  a  replacement  therapy  for
Adrenocortical Insufficiency (“AI”) in children under 17 years of age. The product is the first and only FDA-approved granule hydrocortisone
formulation for the treatment of AI designed for use in children. We acquired U.S. marketing rights to the product in March 2020 and launched
Alkindi Sprinkle in December 2020 with a sales force targeting pediatric endocrinologists. In November 2021, we entered into a co-promotion
agreement with Tolmar Pharmaceuticals, Inc. (“Tolmar”) to use their 60+ person salesforce to promote Alkindi Sprinkle. Tolmar’s sales force will
promote  Alkindi  Sprinkle  to  pediatric  endocrinology  healthcare  professionals  and  Tolmar  will  receive  a  royalty  on  net  sales  growth  above  the
product’s baseline sales level at the time of the transaction. Eton retains ownership of the product and will maintain responsibility for all non-sales
force related commercial activities. We believe there are approximately 10,000 children currently suffering from AI in the United States. Alkindi
Sprinkle  is  protected  by  four  issued  patents  that  extend  to  2034.  In  January  2021,  we  announced  the  acquisition  of  Canadian  rights  to  Alkindi
Sprinkle and we expect to pursue regulatory approval of the product in Canada in the near future.

Carglumic  Acid  tablets  -  Our  Carglumic  Acid  product  is  the  first  and  only  FDA-approved  generic  version  of  Carbaglu®.  Our  product  is
approved for the treatment of acute and chronic hyperammonemia due to N-acetylglutamate Synthase (NAGS) deficiency. We acquired marketing
rights  to  the  product  in  October  2021  and  launched  the  product  in  December  2021.  We  promote  the  product  with  our  internal  sales  force.  The
product was awarded Competitive Generic Therapy (CGT) designation by the FDA, which provides us with 180 days of generic exclusivity. We
believe that the Carbaglu® market is more than $50 million annually and our goal is to capture 25% to 35% of the market.

Dehydrated Alcohol Injection. Our dehydrated alcohol injection product candidate for the treatment of methanol poisoning was submitted to the
FDA and was granted Orphan Drug Exclusivity in late 2020. In May 2021, we received a Complete Response Letter (“CRL”) from the FDA. We
believe  all  of  the  items  raised  by  the  CRL  are  addressable,  and  we  plan  to  submit  our  response  to  the  FDA  in  the  near  future. We  believe  the
dehydrated alcohol injection market is more than $50 million annually.

Zeneo® Hydrocortisone Autoinjector. Our Zeneo hydrocortisone autoinjector product candidate is a proprietary needle-free autoinjector under
development for the treatment of adrenal crisis. We acquired the product candidate from Crossject in June 2021. Currently patients suffering from
adrenal crisis typically use Solu-Cortef, a lyophilized hydrocortisone injection kit that must be reconstituted prior to delivery. The current market
for Solu-Cortef is more than $75 million annually based on IQVIA data. We believe our needle-free autoinjector will be preferred by patients. We
expect to submit a New Drug Application (“NDA”) for the product in 2023, which could allow for FDA approval in 2024.

Hospital Products

Our hospital products category consists of injectable products that are used in the hospital setting. These include:

Biorphen® (phenylephrine HCl). Biorphen is the first and only FDA-approved formulation of ready-to-use phenylephrine injection. Biorphen is
indicated for the treatment of clinically important hypotension resulting primarily from vasodilation in the setting of anesthesia. We acquired U.S.
marketing rights to the product in February 2019. The product was approved in October 2019 and launched in December 2019. We estimate the
current  addressable  market  for  ready-to-use  phenylephrine  to  be  more  than  twenty  million  units  of  Biorphen  annually.  Biorphen  primarily
competes with FDA-approved formulations of concentrated phenylephrine injection, which must be diluted prior to administration to patients, and
with  unapproved  formulations  of  ready-to-use  phenylephrine  sold  by  503B  compounding  pharmacies.  Eton  owns  the  Biorphen  NDA,  but  the
product  is  currently  promoted  by  Xellia  Pharmaceuticals’  (“Xellia”)  hospital  sales  force  under  a  co-promotion  agreement.  Eton  pays  Xellia  a
commission on sales of the product in certain channels. Eton retains the right to exit the co-promotion agreement under certain conditions. We are
actively working on converting this product from its current ampule container to a vial. We expect to launch the vial presentation in 2022, which is
expected to drastically increase the adoption of the product.

Rezipres® (ephedrine HCl).  Rezipres  is  an  innovative  ready-to-use  formulation  of  a  molecule  that  is  indicated  for  the  treatment  of  clinically
important hypotension occurring in the setting of anesthesia. Our product will compete against Emerphed® and non-FDA approved ready-to-use
products from compounding facilities. Rezipres® provides a ready-to-use strength that can be immediately administered to patients, eliminating
the need for calculations and additional dilution steps. Our product is also preservative free and does not contain any sulfites. This product was
launched in March 2022. We have partnered with XGen Pharmaceuticals DJB (“XGen”) for commercialization of the product. XGen’s sales force
is responsible for promoting the product to hospitals. We are actively working on converting the product from its current ampule container to a
vial. We expect to launch the vial presentation in 2022.

Cysteine Injection. Our cysteine injection product candidate is a generic form of EXELA Pharma Sciences’ Elcys® product for which we have
submitted an Abbreviated New Drug Application (“ANDA”) to the FDA. We are actively engaged in the Paragraph IV litigation associated with
the innovator company’s patent. Given our first-to-file status, we expect to be entitled to 180 days of generic exclusivity if we are successful in
challenging the patent. The trial is expected to begin in March of 2022. We believe the current market for Cysteine injection is more than $50
million annually.

Royalty Products

Our royalty products category is comprised of products that Eton does not commercialize. In most cases, these are products that Eton initiated
development of, or licensed at an early stage, and advanced development to an FDA submission before selling the product rights to a third party. These
products are now owned and commercialized partners that pay Eton milestones and royalties on commercial sales. Our royalty products category strategy
allows us to monetize our vast experience and talent in business development, regulatory activities, and product development to generate high returns on
our  financial  investments  without  being  restricted  by  commercial  organization  limitations  and  it  does  not  require  significant  ongoing  overhead  support
costs. We currently have four royalty products: Alway Preservative Free, which is owned and marketed by Bausch Health, and our three neurology oral
liquid products, EPRONTIA™, Zonisamide oral suspension and Lamotrigine oral suspension, which are owned and marketed by Azurity Pharmaceuticals
(“Azurity”).

Alaway® Preservative Free (ketotifen fumarate). Alaway Preservative Free is the first and only preservative-free ophthalmic product approved
for  the  treatment  of  allergic  conjunctivitis.  The  preservative-free  formulation  is  designed  to  deliver  an  improved  comfort  profile  to  patients
compared  to  currently  available  ketotifen  ophthalmic  products  that  contain  preservatives.  The  product  is  sold  via  the  over-the-counter  channel.
Currently, the market for ketotifen ophthalmic products is estimated to be more than $75 million annually based on data from IRI and IQVIA. We
sold the product rights to Bausch Health in February 2019. Bausch Health is responsible for commercialization of the product which was launched
in  February  2021.  We  received  a  $1.5  million  milestone  payment  in  conjunction  with  the  launch  of  the  product  and  receive  a  twelve  percent
royalty on the product’s net sales.

4

 
 
 
 
 
 
 
 
 
 
Neurology Oral Liquids. Starting  in  2018,  we  assembled  a  portfolio  of  three  neurology  oral  liquid  products  through  in-licensing  and  internal
development.  All  three  products  are  molecules  that  are  widely  used  in  oral  solid  forms  to  treat  epilepsy,  but  were  not  FDA-approved  in  liquid
formulations. We believe the formulations will be beneficial to patients suffering from dysphagia, which is prevalent among pediatric and geriatric
patients. In addition, the liquid formulations offer precision dosing, which can provide patients and caregivers with accurate doses that are lower
than or in between the limited strength doses available from oral solid products. We sold these three products to Azurity in February 2021. Under
terms of the agreement, Azurity has paid us $17 million and will pay up to $25 million in additional milestone payments plus a single digit royalty
on net sales of the products. Azurity has taken over ownership of the products and is responsible for all development, regulatory, and commercial
activities. The three neurology oral liquid products are:

EPRONTIA™  (topiramate  oral  solution).  EPRONTIA®  is  the  only  FDA-approved  liquid  formulation  of  topiramate.  The  product  is
approved for three indications, including: monotherapy for treatment of partial-onset or primary general tonic-clonic seizures in patients two
years  of  age  and  older;  adjunctive  therapy  for  treatment  of  partial-onset  seizures,  including  seizures  associated  with  Lennox-Gastaut
syndrome in patients two year of age and older; and as a preventive treatment of migraine in patients 12 years of age and older. The product
was approved in November 2021 and launched by Azurity in December 2021. The current market for topiramate in oral form is more than
$800 million annually according to IQVIA.

Zonisamide Oral Suspension. The product is an innovative liquid formulation of zonisamide under FDA review for the treatment of partial
seizures  in  patients  with  epilepsy.  The  product  application  was  originally  assigned  a  PDUFA  date  of  May  29,  2021  and  the  FDA  issued  a
Complete  Response  Letter  because  it  was  unable  to  inspect  the  manufacturing  site  due  to  COVID-related  travel  restrictions.  The  FDA
inspected the facility in January 2022, and we believe the application could be approved in the near future. The current market for zonisamide
in oral form is more than $65 million annually according to IQVIA.

Lamotrigine for Oral Suspension. The product is an innovative liquid formulation of lamotrigine under FDA review for the treatment of
partial on-set seizures, primary generalized tonic-clonic seizures, and seizures of Lennox-Gastaut syndrome in patients two year of age and
older. The product has been issued a patent, which is now owned by Azurity. The product’s NDA application received a Complete Response
Letter in March 2020 and the FDA requested changes to the Dosage and Administration section of the product’s Prescribing Information to
simplify  the  dosing  information  for  intended  users.  The  FDA  requested  a  human  factors  validation  study  with  the  revised  labeling  to
demonstrate that the intended users can prepare and administer the oral suspension safely and effectively. Our development partner completed
the study and submitted the report to the FDA in November 2021. The application has been assigned a PDUFA date of May 30, 2022. The
current market for lamotrigine in oral form is more than $600 million annually according to IQVIA.

Goals and Strengths

Our goal is to become a leading profitable pharmaceutical company that brings innovative treatments to patients. We believe we are unique in the
pharmaceutical industry in our ability to identify, acquire, and advance products through the development and regulatory process. Our biggest competitive
strengths are:

● Business  development  experience–  our  ability  to  identify  and  execute  transactions  on  under-appreciated  development  assets.  Our  team  has
completed  over  150  business  development  transactions  throughout  their  careers  and  their  industry  connections  and  track  record  provide  the
company with proprietary deal flow. We avoid participating in broker led transactions of auction processes.

● Regulatory expertise  –  our  knowledge  and  experience  gaining  FDA  approval,  and  particularly  our  knowledge  within  the  505(b)(2)  regulatory
pathway,  which  provides  drug  sponsors  with  the  opportunity  to  leverage  existing  data  or  literature  to  drastically  expedite  drug  development
timelines and reduce investment.

Sales and Marketing

We currently own or have economic interests in six commercial products. We typically commercialize our orphan products under our own label
with our internal infrastructure and sales force, however, we may at times supplement our efforts with a co-promotion arrangement as we have with Tolmar
Pharmaceuticals  on  Alkindi  Sprinkle.  In  our  orphan  product  category,  we  currently  commercialize  Alkindi  Sprinkle  and  Carglumic  Acid  in  the  United
States. These products are distributed to patients via a specialty pharmacy, which supports customer service and reimbursement activities.

In  our  hospital  category,  we  have  entered  into  short-term  co-promotion  agreements  for  the  ampule  format  of  both  Biorphen  and  Rezipres.  We
retain ownership of the products and have no commercial arrangements relating to the vial formats of both products. For each future product launch we will
assess if it is more advantageous to promote internally with our own sales force or partner with a company with an existing hospital sales force.

In our royalty product category, the products are commercialized by our partners. Bausch Health is responsible for all sale and marketing activities
related to Alaway Preservative Free, and Azurity is responsible for all sales and marketing activities related to Eprontia, zonisamide oral suspension, and
lamotrigine suspension. In all cases we receive a royalty on net sales of the products

In January 2020 we signed a co-promotion agreement with Xellia for the promotion of Biorphen. Under terms of the agreement, Xellia’s U.S.-
based hospital sales force will promote Biorphen in certain customer channels in exchange for a commission based on net sales realized at certain customer
accounts. Eton owns the Biorphen NDA and the product is sold under Eton’s brand name. The agreement has a five-year term, but allows Eton to exit
under various scenarios, including a change of control, and after 2021 if Biorphen net sales from Xellia designated accounts do not exceed $29.4 million in
2021, or $42.0 million in 2022 and the following years. In July 2021 we signed a co-promotion agreement with XGen whereby XGen’s salesforce will
promote Rezipres for a three-year term, in exchange for a profit share on the Rezipres product. In November 2021 we signed a co-promotion agreement
with Tolmar whereby Tolmar will promote Alkindi Sprinkle® through its 60+ person salesforce in exchange for a royalty on net sales.

Research and Development

We  currently  have  seven  employees  that  support  our  product  research  and  development  activities.  In  addition,  we  utilize  external  sources  for
various product development activities, including the resources of our product development partners for certain product candidates, and also through the
use of contract laboratory services on a fee for service model.

Manufacturing and Suppliers

We rely on third-party contract manufacturing organizations (“CMOs”) to manufacture our products. All our manufacturing partners are based in
the  United  States  or  Europe.  We  seek  to  work  with  CMOs  that  have  a  long  history  of  quality  and  FDA  compliance.  All  products  are  manufactured  in
compliance with current Good Manufacturing Processes (“cGMP”), and our internal quality system requires us to enter quality agreements with and audit
all of our manufacturers prior to commercializing the product. Our choice to rely on external manufacturers significantly reduces the amount of capital
invested in our business and allows us the flexibility to pursue a broad range of opportunities beyond the specific capabilities of a single facility.

Intellectual Property

Our  policy  is  to  seek  to  protect  our  proprietary  position  by,  among  other  methods,  filing  U.S.  and  foreign  patent  applications  related  to  our
proprietary technology, inventions and improvements that are important to the development of our business. We also rely on our trade secrets, know-how
and continuing technological innovation to develop and maintain our proprietary position. We vigorously defend our intellectual property to preserve our
rights and gain the benefit of our technological investments. Our business is not dependent, however, upon any single patent, trademark or contract.

Alkindi Sprinkle is protected by four issued patents that extend to 2034. We intend to seek patent protection on our internally developed products

as circumstances warrant.

Our  development  partners  for  zonisamide  and  topiramate  have  filed  patent  applications  on  those  products  and  our  development  partner  for
lamotrigine was granted a patent by the United States Patent and Trademark Office for the product’s unique formulation. We expect the lamotrigine patent
to be Orange Book listed after product approval. These patents were assigned to Azurity in February 2021.

Government Regulations and Funding

Pharmaceutical companies are subject to extensive regulation by foreign, federal, state and local agencies, such as the FDA, and various European
regulatory authorities. The manufacture, distribution, marketing and sale of pharmaceutical products are subject to government regulation in the United
States  and  various  foreign  countries.  Additionally,  in  the  United  States,  we  must  follow  rules  and  regulations  established  by  the  FDA  requiring  the
presentation of data indicating that our products are safe and efficacious and are manufactured in accordance with cGMP regulations. If we do not comply
with applicable requirements, we may be fined, the government may refuse to approve our marketing applications or allow us to manufacture or market our
products, and we may be criminally prosecuted. We, our manufacturers and contract research organizations (“CROs”) may also be subject to regulations
under other foreign, federal, state and local laws, including, but not limited to, the U.S. Occupational Safety and Health Act, the Resource Conservation and
Recovery Act, the Clean Air Act and import, export and customs regulations as well as the laws and regulations of other countries. The U.S. government
has increased its enforcement activity regarding illegal marketing practices domestically and internationally. As a result, pharmaceutical companies must
ensure their compliance with the Foreign Corrupt Practices Act and federal healthcare fraud and abuse laws, including the False Claims Act.

These regulatory requirements impact our operations and differ from one country to another, so that securing the applicable regulatory approvals
of one country does not imply the approval of another country. The approval procedures involve high costs and are manpower intensive, usually extend
over many years and require highly skilled and professional resources.

FDA Market Approval Process

The steps required to be taken before a new drug may be marketed in the United States generally include:

● completion of pre-clinical laboratory and animal testing;

● completion of required chemistry, manufacturing and controls testing;

● the submission to the FDA of an investigational new drug, or IND, the application for which must be evaluated and found acceptable by the

FDA before human clinical trials may commence;

● performance of adequate and well-controlled human clinical trials to establish the safety, pharmacokinetics and efficacy of the proposed drug

for its intended use;

● submission and approval of an NDA; and

● agreement with FDA of the language on the package insert.

Clinical  studies  are  conducted  under  protocols  detailing,  among  other  things,  the  objectives  of  the  study,  what  types  of  patients  may  enter  the
study, schedules of tests and procedures, drugs, dosages, and length of study, as well as the parameters to be used in monitoring safety, and the efficacy
criteria  to  be  evaluated.  A  protocol  for  each  clinical  study  and  any  subsequent  protocol  amendments  must  be  submitted  to  the  FDA  as  part  of  the  IND
process.

Clinical trials are usually conducted in three phases. Phase 1 clinical trials are normally conducted in small groups of healthy volunteers to assess
safety of various dosing regimens and pharmacokinetics. After a safe dose has been established, in Phase 2 clinical trials the drug is administered to small
populations of sick patients to look for initial signs of efficacy in treating the targeted disease or condition and to continue to assess safety. Phase 3 clinical
trials are usually multi-center, double-blind controlled trials in larger numbers of subjects at various sites to assess as fully as possible both the safety and
effectiveness of the drug.

Clinical trials must be conducted in accordance with the FDA’s good clinical practices (“GCP”) requirements. The FDA may order the temporary
or  permanent  discontinuation  of  a  clinical  study  at  any  time  or  impose  other  sanctions  if  it  believes  that  the  clinical  study  is  not  being  conducted  in
accordance  with  FDA  requirements  or  that  the  participants  are  being  exposed  to  an  unacceptable  health  risk.  An  institutional  review  board  (“IRB”)
generally  must  approve  the  clinical  trial  design  and  patient  informed  consent  at  study  sites  that  the  IRB  oversees  and  also  may  halt  a  study,  either
temporarily  or  permanently,  for  failure  to  comply  with  the  IRB’s  requirements,  or  may  impose  other  conditions.  Additionally,  some  clinical  studies  are
overseen by an independent group of qualified experts organized by the clinical study sponsor, known as a data safety monitoring board or committee. This
group recommends whether or not a trial may move forward at designated check points based on access to certain data from the study. The clinical study
sponsor may also suspend or terminate a clinical trial based on evolving business objectives and/or competitive climate.

As a product candidate moves through the clinical testing phases, manufacturing processes are further defined, refined, controlled and validated.
The level of control and validation required by the FDA increases as clinical studies progress. We and the third-party manufacturers on which we rely for
the  manufacture  of  our  product  candidates  and  their  respective  components  (including  the  active  pharmaceutical  ingredient  (“API”))  are  subject  to
requirements  that  drugs  be  manufactured,  packaged  and  labeled  in  conformity  with  cGMP.  To  comply  with  cGMP  requirements,  manufacturers  must
continue to spend time, money and effort to meet requirements relating to personnel, facilities, equipment, production and process, labeling and packaging,
quality control, recordkeeping and other requirements.

Assuming  completion  of  all  required  testing  in  accordance  with  all  applicable  regulatory  requirements,  detailed  information  on  the  product
candidate is submitted to the FDA in the form of an NDA, requesting approval to market the product for one or more indications, together with payment of
a user fee, unless waived. An NDA includes all relevant data available from pertinent nonclinical and clinical studies, including negative or ambiguous
results as well as positive findings, together with detailed information on the chemistry, manufacture, controls and proposed labeling, among other things.
To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and efficacy of the product candidate for
its intended use to the satisfaction of the FDA.

If  an  NDA  submission  is  accepted  for  filing,  the  FDA  begins  an  in-depth  review  of  the  NDA.  Under  the  Prescription  Drug  User  Fee  Act
(“PDUFA”) the FDA’s goal is to complete its initial review and respond to the applicant within ten months of submission, unless the application relates to
an unmet medical need, or is for a serious or life-threatening indication, in which case the goal may be within six months of NDA submission. However,
the review process and the target response date under PDUFA may be extended if the FDA requests or the NDA sponsor otherwise provides additional
information or clarification regarding information already provided in the NDA. During its review of an NDA, the FDA may refer the application to an
advisory  committee  for  review,  evaluation  and  recommendation  as  to  whether  the  application  should  be  approved.  The  FDA  is  not  bound  by  the
recommendation of an advisory committee, but it typically follows such recommendations. Data from clinical studies are not always conclusive and the
FDA and/or any advisory committee it appoints may interpret data differently than the applicant.

After  the  FDA  evaluates  the  NDA  and  inspects  manufacturing  facilities  where  the  drug  product  and/or  its  API  will  be  produced,  it  will  either
approve commercial marketing of the drug product with prescribing information for specific indications or issue a CRL indicating that the application is
not ready for approval and stating the conditions that must be met in order to secure approval of the NDA. If the CRL requires additional data and the
applicant subsequently submits that data, the FDA nevertheless may ultimately decide that the NDA does not satisfy its criteria for approval. The FDA
could also approve the NDA with a Risk Evaluation and Mitigation Strategies (“REMS”) plan to mitigate risks, which could include medication guides,
physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools.
The FDA also may condition approval on, among other things, changes to proposed labeling, development of adequate controls and specifications, or a
commitment  to  conduct  post-marketing  testing.  Such  post-marketing  testing  may  include  Phase  4  clinical  trials  and  surveillance  to  further  assess  and
monitor the product’s safety and efficacy after approval.

8

 
 
 
 
 
 
 
If the FDA approves one of our product candidates, we will be required to comply with a number of post-approval regulatory requirements. We
would  be  required  to  report,  among  other  things,  certain  adverse  reactions  and  production  problems  to  the  FDA,  provide  updated  safety  and  efficacy
information  and  comply  with  requirements  concerning  advertising  and  promotional  labeling  for  any  of  our  products.  Also,  quality  control  and
manufacturing  procedures  must  continue  to  conform  to  cGMP  after  approval,  and  the  FDA  periodically  inspects  manufacturing  facilities  to  assess
compliance  with  cGMP,  which  imposes  extensive  procedural,  substantive  and  record  keeping  requirements.  If  we  seek  to  make  certain  changes  to  an
approved product, such as certain manufacturing changes, we will need FDA review and approval before the change can be implemented. For example, if
we change the manufacturer of a product or our API, the FDA may require stability or other data from the new manufacturer, and such data will take time
and are costly to generate, and the delay associated with generating these data may cause interruptions in our ability to meet commercial demand, if any.
While physicians may use products for indications that have not been approved by the FDA, we may not label or promote the product for an indication that
has not been approved. Securing FDA approval for new indications is similar to the process for approval of the original indication and requires, among
other things, submitting data from adequate and well-controlled studies that demonstrate the product’s safety and efficacy in the new indication. Even if
such studies are conducted, the FDA may not approve any change in a timely fashion, or at all.

The FDA may also require post-marketing testing, or Phase 4 testing, as well as risk minimization action plans and surveillance to monitor the

effects of an approved product or place conditions or an approval that could otherwise restrict the distribution or use of the product.

Section 505(b)(2) New Drug Applications

We intend to submit applications for certain product candidates via the 505(b)(2) regulatory pathway. As an alternate path for FDA approval of
new  indications  or  new  formulations  of  previously  approved  products,  a  company  may  submit  a  Section  505(b)(2)  NDA,  instead  of  a  “stand-alone”  or
“full” NDA. Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act (“FDCA”) was enacted as part of the Drug Price Competition and Patent Term
Restoration Act of 1984, otherwise known as the Hatch-Waxman Amendments. Section 505(b)(2) permits the submission of an NDA where at least some
of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of
reference. Some examples of products that may be allowed to follow a 505(b)(2) path to approval are drugs that have a new dosage form, strength, route of
administration, formulation or indication.

The Hatch-Waxman Amendments permit the applicant to rely upon certain published nonclinical or clinical studies conducted for an approved
product or the FDA’s conclusions from prior review of such studies. The FDA may require companies to perform additional studies or measurements to
support  any  changes  from  the  approved  product.  The  FDA  may  then  approve  the  new  product  for  all  or  some  of  the  labeled  indications  for  which  the
reference product has been approved, as well as for any new indication supported by the Section 505(b)(2) application. While references to nonclinical and
clinical data not generated by the applicant or for which the applicant does not have a right of reference are allowed, all development, process, stability,
qualification and validation data related to the manufacturing and quality of the new product must be included in an NDA submitted under Section 505(b)
(2).

To  the  extent  that  the  Section  505(b)(2)  applicant  is  relying  on  the  FDA’s  conclusions  regarding  studies  conducted  for  an  already  approved
product, the applicant is required to certify to the FDA concerning any patents listed for the approved product in the FDA’s Approved Drug Products with
Therapeutic Equivalence Evaluations, or Orange Book. Specifically, the applicant must certify that: (i) the required patent information has not been filed;
(ii) the listed patent has expired; (iii) the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or
(iv) the listed patent is invalid or will not be infringed by the new product. The Section 505(b)(2) application also will not be approved until any non-patent
exclusivity, such as exclusivity for obtaining approval of a new chemical entity, listed in the Orange Book for the reference product has expired. If the
Orange Book certifications outlined above are not accomplished, the Section 505(b)(2) applicant may invest a significant amount of time and expense in
the development of its products only to be subject to significant delay and patent litigation before its products may be commercialized.

Section 505(j) Abbreviated New Drug Applications

The 505(j) pathway is used for product candidates that are therapeutically equivalent to an approved product. The underlying premise of the 505(j)
pathway is that a product candidate classified as therapeutically equivalent can be substituted for the approved product with the full expectation that the
substituted  product  will  produce  the  same  clinical  effect  and  safety  profile  as  the  approved  product  when  administered  under  the  same  conditions.  A
product  candidate  utilizing  the  505(j)  pathway  requires  an  abbreviated  new  drug  application,  or  ANDA,  which  relies  on  the  FDA’s  finding  that  the
previously approved drug candidate is safe and effective. An ANDA generally must contain information to show that the product candidate is the same as
the  approved  product  with  respect  to  API,  conditions  of  use,  route  of  administration,  dosage  form,  strength  and  labeling,  with  certain  permissible
differences, and is the bioequivalent of the approved drug. The 505(j) pathway typically requires no clinical testing other than a bioequivalence trial. While
the  505(j)  pathway  is  typically  shorter  and  less  expensive  than  the  505(b)(2)  pathway,  the  505(b)(2)  pathway  allows  greater  flexibility  as  to  the
characteristics of the product candidate.

Other U.S. Healthcare Laws and Compliance Requirements

For  products  distributed  in  the  United  States,  we  will  also  be  subject  to  additional  healthcare  regulation  and  enforcement  by  the  federal

government and the states in which we conduct our business. Applicable federal and state healthcare laws and regulations include the following:

● The  U.S.  Anti-Kickback  Statute  prohibits,  among  other  things,  persons  from  knowingly  and  willfully  soliciting,  offering,  receiving,  or
providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase,
order,  lease,  or  recommendation  of,  any  good  or  service,  for  which  payment  may  be  made  under  federal  healthcare  programs  such  as
Medicare and Medicaid;

● The  federal  civil  and  criminal  false  claims  laws,  including  the  U.S.  False  Claims  Act,  can  be  enforced  by  individuals,  on  behalf  of  the
government,  through  civil  whistleblower  or  qui  tam  actions,  and  the  civil  monetary  penalties  law,  prohibits  individuals  or  entities  from,
among  other  things,  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government  claims  for  payment  that  are  false  or
fraudulent or making a false statement to avoid, decrease, or conceal an obligation to pay money to the federal government;

● The Health  Insurance  Portability  and  Accountability  Act  of  1996  (“HIPAA”),  which  prohibits,  among  other  things,  executing  a  scheme  to
defraud  any  healthcare  benefit  program  and  knowingly  and  willfully  falsifying,  concealing  or  covering  up  a  material  fact  or  making  any
materially false statement in connection with the delivery of or payment for healthcare benefits, items, or services;

● HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  and  their  implementing  regulations,
imposes  obligations,  including  mandatory  contractual  terms,  with  respect  to  safeguarding  the  privacy,  security  and  transmission  of
individually identifiable health information;

● The 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 certain exceptions) to report annually to the
Centers  for  Medicare  &  Medicaid  Services  (“CMS”)  information  related  to  payments  or  other  transfers  of  value  made  to  physicians  and
teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members; and

● Analogous state laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing arrangements and
claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private 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;  state  and  local  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;  state  laws  that  require  the
reporting  of  information  related  to  drug  pricing;  state  and  local  laws  requiring  the  registration  of  pharmaceutical  sales  and  medical
representatives;  and  state  and  foreign  laws,  such  as  the  General  Data  Protection  Regulation  (EU)  2016/679,  governing  the  privacy  and
security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted
by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of available statutory exceptions and regulatory safe harbors, it is possible that some of
our business activities could be subject to challenge under one or more of such laws. If our operations are found to be in violation of any of the federal or
state laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including significant criminal, civil, and
administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government healthcare programs, integrity oversight
and reporting obligations to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations.

Reimbursement

Sales of our products in the United States may depend, in part, on the extent to which the costs of the products will be covered and reimbursed by
third-party  payors,  such  as  government  health  programs,  commercial  insurance  and  managed  health  care  organizations.  These  third-party  payors  are
increasingly challenging the prices charged for medical products and services. Additionally, the containment of health care costs has become a priority of
federal  and  state  governments,  and  the  prices  of  drugs  have  been  a  focus  in  this  effort.  The  United  States  government,  state  legislatures  and  foreign
governments  have  shown  significant  interest  in  implementing  cost-containment  programs,  including  price  controls,  restrictions  on  reimbursement  and
requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in
jurisdictions with existing controls and measures, could further limit our net revenue and results. If these third-party payors do not consider our products to
be cost-effective compared to other available therapies, they may not cover our products after approval as a benefit under their plans or, if they do, the level
of payment may not be sufficient to allow us to sell our products on a profitable basis.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, (the “MMA”), imposed new requirements for the distribution and
pricing of prescription drugs for Medicare beneficiaries and included a major expansion of the prescription drug benefit under Medicare Part D. Under Part
D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities which will provide coverage of outpatient prescription drugs.
Part D plans include both stand-alone prescription drug benefit plans and prescription drug coverage as a supplement to Medicare Advantage plans. Unlike
Medicare Parts A and B, Part D coverage is not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs,
and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug
formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or
class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Government
payment for some of the costs of prescription drugs may increase demand for products for which we receive marketing approval. However, any negotiated
prices for our products covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain. Moreover, while the
MMA applies only to drug benefits for Medicare beneficiaries, private third-party payors often follow Medicare coverage policy and payment limitations in
setting  their  own  payment  rates.  Any  reduction  in  payment  that  results  from  the  MMA  may  result  in  a  similar  reduction  in  payments  from  non-
governmental payors.

Decreases in third-party reimbursement for our products or a decision by a third-party payor to not cover our products could reduce physician

usage of the products and have a material adverse effect on our sales, results of operations and financial condition.

Healthcare Reform

In  the  United  States  and  some  foreign  jurisdictions,  there  have  been  a  number  of  legislative  and  regulatory  changes  and  proposed  changes
regarding the health care system that could prevent or delay marketing approval pharmaceutical products, restrict or regulate post-approval activities and
affect our ability to profitably sell our product candidates. Legislative and regulatory proposals have been made to expand post-approval requirements and
restrict sales and promotional activities for pharmaceutical products.

For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act,
(collectively, the “Health Care Reform Law”) was enacted, which substantially changes the way health care is financed by both governmental and private
insurers, and significantly impacts the U.S. pharmaceutical industry. The Health Care Reform Law, among other things, imposed reporting requirements on
manufacturers related to drug samples and financial relationships with physicians and teaching hospitals, increased the minimum Medicaid rebates owed by
manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations,
established annual fees on manufacturers of certain branded prescription drugs, and established a Medicare Part D coverage gap discount program.

11

 
 
 
 
 
 
 
 
 
Some of the provisions of the Health Care Reform Law have yet to be implemented, and there have been judicial and Congressional challenges to
certain aspects of the Health Care Reform Law. In addition, Congress has considered legislation that would repeal or repeal and replace all or part of the
Health Care Reform Law. While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under
the Health Care Reform Law have been signed into law. The Tax Cuts and Jobs Act of 2017 (the “Tax Act”) included a provision which repealed, effective
January  1,  2019,  the  tax-based  shared  responsibility  payment  imposed  by  the  Health  Care  Reform  Law  on  certain  individuals  who  fail  to  maintain
qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” The Bipartisan Budget Act of 2018, among
other things, amended the Health Care Reform, effective January 1, 2019, to increase from 50 percent to 70 percent the point-of-sale discount that is owed
by pharmaceutical manufacturers who participate in Medicare Part D and to close the coverage gap in most Medicare drug plans, commonly referred to as
the  “donut  hole”.  In  2018,  a  Texas  U.S.  District  Court  Judge  ruled  that  the  Health  Care  Reform  Law  is  unconstitutional  in  its  entirety  because  the
“individual  mandate”  was  repealed  by  Congress  as  part  of  the  Tax  Act.  While  the  ruling  has  no  immediate  effect  pending  appeal  of  the  decision,  it  is
unclear how this decision, subsequent appeals, and other efforts to repeal and replace the Health Care Reform will impact the Health Care Reform Law.

In addition, other legislative changes have been proposed and adopted in the United States since the Health Care Reform Law was enacted. These
changes  include,  among  others,  aggregate  reductions  of  Medicare  payments  to  providers  of  up  to  2%  per  fiscal  year  and  an  increase  in  the  statute  of
limitations period for the government to recover overpayments to providers from three to five years.

Further,  there  has  been  heightened  governmental  scrutiny  in  the  United  States  of  pharmaceutical  pricing  practices  in  light  of  the  rising  cost  of
prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation
designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs,
and reform government program reimbursement methodologies for products. For example, in President Biden’s 2022 State of the Union Speech, President
Biden again called for Congress to take action to combat high prices of prescription drugs. In 2019, the Health and Human Services (“HHS”) Office of
Inspector General proposed modifications to the U.S. Anti-Kickback Statute discount safe harbor for the purpose of reducing the cost of drug products to
consumers  which,  among  other  things,  if  finalized,  will  affect  discounts  paid  by  manufacturers  to  Medicare  Part  D  plans,  Medicaid  managed  care
organizations and pharmacy benefit managers working with these organizations. While some of these and other proposed measures may require additional
authorization to become effective, Congress and government administration officials have each indicated that they will continue to seek new legislative
and/or administrative measures to control drug costs.

Risk Factor Summary

You should carefully consider the risks set forth in the section of this Annual Report of Form 10-K entitled “Risk Factors” beginning on page 16

of this Annual Report, including, but not limited to, the following:

● We are a specialty pharmaceutical company with a limited operating history, and it is difficult for potential investors to evaluate our business.

● Our business is adversely affected by the ongoing coronavirus pandemic and the impact could be material.

● We may have significant research, regulatory and development expenses as we advance our product candidates.

● We may need to grow the size of our organization, and we may experience difficulties in managing this growth.

● If product  liability  lawsuits  are  brought  against  us,  we  may  incur  substantial  liabilities  and  may  be  required  to  limit  commercialization  of  our

product candidates.

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

● We  rely  significantly  on  information  technology  and  any  failure,  inadequacy,  interruption  or  security  lapse  of  that  technology,  including  any

cybersecurity incidents, could harm our ability to operate our business effectively.

● Sales of counterfeits of any of our product candidates, as well as unauthorized sales of any of our product candidates, may have adverse effects on

our revenues, business and results of operations and damage our brand and reputation.

● We  have  entered  into  several  arrangements  with  related  parties  for  the  development  and  marketing  of  certain  product  candidates  and  these

arrangements present potential conflicts of interest.

● We  face  competition  from  other  biotechnology  and  pharmaceutical  companies  and  our  operating  results  will  suffer  if  we  fail  to  compete

effectively.

● Our competitors may obtain FDA or other regulatory approval for comparable products more rapidly than we may obtain approval for ours, and
the risk of our competitors doing so may lead us to develop drug candidates without disclosing certain information with regard to such candidates.

● If we  are  not  able  to  obtain  any  required  regulatory  approvals  for  our  product  candidates,  we  will  not  be  able  to  commercialize  our  product

candidate and our ability to generate revenue will be limited.

● If  the  FDA  does  not  conclude  that  our  product  candidates  satisfy  the  requirements  for  the  505(b)(2)  regulatory  approval  pathway,  or  if  the
requirements for approval of any of our product candidates under Section 505(b)(2) are not as we expect, the approval pathway for our product
candidates  will  likely  take  significantly  longer,  cost  significantly  more  and  encounter  significantly  greater  complications  and  risks  than
anticipated, and in any case may not be successful.

● An NDA submitted under Section 505(b)(2) subjects us to the risk that we may be subject to a patent infringement lawsuit that would delay or

prevent the review or approval of our product candidate.

● Even if we receive regulatory approval for any of our product candidates, 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 are  subject  to  ongoing  obligations  and  continued  regulatory  review,  which  may  result  in  significant  additional  expense.  Additionally,  our
product candidates could be subject to labeling and other restrictions and withdrawal from the market, and we may be subject to penalties if we
fail to comply with regulatory requirements or if we experience unanticipated problems with our product candidates.

● Significant additional labeling or warning requirements or limitations on the availability of our products may inhibit sales of affected products.

● Current  and  future  legislation  may  increase  the  difficulty  and  cost  for  us  to  obtain  marketing  approval  of  and  commercialize  our  product

candidates and affect the prices we may obtain.

● Our future  growth  may  depend,  in  part,  on  our  ability  to  penetrate  international  markets,  where  we  would  be  subject  to  additional  regulatory

burdens and other risks and uncertainties.

● If we market any of our products or product candidates in a manner that violates health care fraud and abuse laws, or if we violate government

price reporting laws, we may be subject to civil or criminal penalties.

● We may not be able to establish agreements with third parties with whom we wish to collaborate and, if we are able to establish them, we may not
be able to establish them on commercially reasonable terms, which could result in alterations or delays of our development and commercialization
plans.

● We expect  to  rely  on  third  parties  to  conduct  clinical  trials  for  our  product  candidates.  If  these  third  parties  do  not  successfully  carry  out  their
contractual  duties  or  meet  expected  deadlines,  we  may  not  be  able  to  obtain  regulatory  approval  for  or  commercialize  any  of  our  product
candidates and our business would be substantially harmed.

● We enter  into  various  contracts  in  the  normal  course  of  our  business,  some  or  all  of  which  may  require  us  to  indemnify  the  other  party  to  the
contract.  In  the  event  we  have  to  perform  under  these  indemnification  provisions,  it  could  have  an  adverse  effect  on  our  business,  financial
condition and results of operations.

● Our  Chief  Executive  Officer  holds  ownership  interest  in  some  of  the  third  parties  we  have  entered  into  agreements  with.  The  terms  and  fee
arrangements of these agreements, we believe, approximate the terms and fee arrangements of an agreement that would have been obtained in an
arm’s length and unaffiliated transaction. Nonetheless, this may expose us to claims of interested transactions and other fiduciary suits.

● Any termination or suspension of, or delays in the commencement or completion of, any necessary studies of any of our product candidates for

any indications could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.

● Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be

predictive of future trial results.

● Third-party coverage and reimbursement and health care cost containment initiatives and treatment guidelines may constrain our future revenues.

● 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.

● We  will  depend  on  rights  to  certain  pharmaceutical  compounds  that  have  been  acquired  by  us.  We  do  not  have  complete  control  over  these

pharmaceutical compounds and any loss of our rights to them could prevent us from selling our products.

● It is difficult and costly to protect our intellectual property rights, and we cannot ensure the protection of these rights.

● Changes in either U.S. or foreign patent law or interpretation of such laws could diminish the value of patents in general, thereby impairing our

ability to protect our products.

● Our  product  candidates  may  infringe  the  intellectual  property  rights  of  others,  which  could  increase  our  costs  and  delay  or  prevent  our

development and commercialization efforts.

● Others  may  claim  an  ownership  interest  in  our  intellectual  property,  which  could  expose  us  to  litigation  and  have  an  adverse  effect  on  our

prospects.

● We may be subject to claims that we have wrongfully hired an employee from a competitor or that we or our employees have wrongfully used or

disclosed alleged confidential information or trade secrets of their former employers.

Item 1A. Risk Factors

We operate in a dynamic and rapidly changing environment that involves numerous risks and uncertainties. Certain factors may have a material
adverse  effect  on  our  business,  financial  condition  and  results  of  operations,  and  you  should  carefully  consider  them.  Accordingly,  in  evaluating  our
business, we encourage you to consider the following discussion of risk factors, in its entirety, in addition to other information contained in this Annual
Report on Form 10-K and our other public filings with the SEC. Other events that we do not currently anticipate or that we currently deem immaterial may
also affect our results of operations and financial condition.

Risks Relating to Our Business

We are a specialty pharmaceutical company with a limited operating history, and it is difficult for potential investors to evaluate our business.

We  are  a  specialty  pharmaceutical  company  founded  in  April  2017  and  have  only  recently  commenced  revenue-producing  operations  and  our
historical  operations  have  primarily  consisted  of  the  preliminary  formulation,  testing  and  development  of  our  various  product  candidates.  Our  limited
operating  history  makes  it  difficult  for  potential  investors  to  evaluate  our  initial  product  candidates  or  our  prospective  operations.  As  an  early-stage
company, we are subject to all the risks inherent in the initial organization, financing, expenditures, complications and delays in a new business. Further,
biopharmaceutical  product  development  is  a  highly  speculative  undertaking,  involves  a  substantial  degree  of  risk  and  is  a  capital-intensive  business.
Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by companies in the early
stages of product development and commercialization, especially clinical-stage biopharmaceutical companies such as ours. As a company with a limited
operating history, we may be unable to:

● successfully implement or execute our current business plan, or develop a business plan that is sound;

● successfully complete clinical trials and obtain regulatory approval for the marketing of our additional product candidates;

● successfully contract for the manufacture of our clinical drug products and establish a commercial drug supply;

● secure market exclusivity or adequate intellectual property protection for our product candidates;

● attract and retain an experienced management and advisory team; or

● raise sufficient funds in the capital markets to effectuate our business plan, including clinical development, regulatory approval and ongoing

commercialization for our product candidates.

There can be no assurance that our efforts will be successful or that we will ultimately be able to attain profitability. If we cannot successfully

execute any one of the foregoing, our business may not succeed.

Our business is adversely affected by the ongoing coronavirus pandemic and the impact could be material.

Public  health  outbreaks,  epidemics  or  pandemics  have  had,  and  could  in  the  future  have,  an  adverse  impact  on  our  operations  and  financial
condition. The  continuing  pandemic  caused  by  the  novel  strain  of  coronavirus  (COVID-19)  has  caused  many  countries,  including  the  United  States,  to
declare national emergencies and implement preventive measures such as travel bans and shelter-in-place or total lock-down orders, some of which have
eased. The continuation or re-implementation of these bans and orders remains uncertain. In some cases, these bans and orders have influenced certain
aspects of our business. For example, we began commercializing our Biorphen product in December 2019 and Alkindi Sprinkle product in December 2020;
however, we have encountered difficulty in creating significant market pull-through demand for our products in 2020 and 2021 as our in-person sales calls
to key personnel at hospitals and surgical centers and introductory product presentation seminars were limited as a result of the COVID-19 pandemic. We
are working on other promotional efforts to drive further adoption in the market, but we may see our product sales and marketing efforts continue to be
adversely affected by the pandemic in 2022 and beyond. COVID-19 may also affect our ability to complete recruitment and data analysis for our clinical
trials and our ability to conduct research and development of our complement programs in our planned timeframe. The extent to which COVID-19 impacts
our  operations  will  depend  on  future  developments,  which  are  highly  uncertain  and  cannot  be  predicted  with  confidence,  including  the  duration  and
severity of the outbreak, and the actions that may be required to contain COVID-19 or treat its impact. In particular, as a result of the COVID-19 pandemic,
we may experience disruptions that could severely impact our business, preclinical studies, drug manufacturing and clinical trials including:

● diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and

hospital staff supporting the conduct of our clinical trials;

● interruption of  key  clinical  trial  activities,  such  as  clinical  trial  site  data  monitoring,  due  to  limitations  on  travel  imposed  or  recommended  by
federal  or  state  governments,  employers  and  others  or  interruption  of  clinical  trial  subject  visits  and  study  procedures,  which  may  impact  the
integrity of subject data and clinical study endpoints;

● interruption or delays in the operations of the FDA or other regulatory authorities, which may impact review and approval timelines; and

● interruption of, or delays in promoting our products in-person, at conferences and at hospitals due to limitations on travel and in-person gatherings

imposed or recommended by federal or state governments.

We may need to grow the size of our organization, and we could experience difficulties in managing this growth.

As  our  development  and  commercialization  plans  and  strategies  develop,  we  may  need  to  expand  the  size  of  our  employee  and
consultant/contractor  base.  Future  growth  would  impose  significant  added  responsibilities  on  members  of  management,  including  the  need  to  identify,
recruit, maintain, motivate and integrate additional employees. In addition, our management may have to divert a disproportionate amount of its attention
away from our day-to-day activities and devote a substantial amount of time to managing these growth activities. Our future financial performance and our
ability to commercialize our product candidates and any other future product candidates and our ability to compete effectively will depend, in part, on our
ability to effectively manage our future growth.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product
candidates.

We face a potential risk of product liability as a result of the commercialization of our approved products and clinical testing of our new product
candidates and will face an even greater risk if we commercialize our current product candidates or any other future product. For example, we may be sued
if our approved products or any product we develop, including any of our product candidates, or any materials that we use in our products allegedly causes
injury  or  is  found  to  be  otherwise  unsuitable  during  product  testing,  manufacturing,  marketing  or  sale.  Any  such  product  liability  claims  may  include
allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability and a breach of
warranties. In the United States, claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against
product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates. Even successful defense
would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

● decreased demand for our current products or any of our product candidates or any future products that we may develop;

● injury to our reputation;

● withdrawal of clinical trial participants;

● costs to defend the related litigation;

● a diversion of management’s time and our resources;

● substantial monetary awards to trial participants or patients;

● product recalls, withdrawals or labeling, marketing or promotional restrictions;

● the inability to commercialize some or all of our product candidates; and

● a decline in the value of our stock.

We  carry  product  liability  insurance  we  consider  adequate  for  our  current  level  of  expected  product  sales,  clinical  testing  and  product
development.  Our  inability  to  obtain  and  retain  sufficient  product  liability  insurance  at  an  acceptable  cost  to  protect  against  potential  product  liability
claims could prevent or inhibit the commercialization of our approved products or additional products we develop. Although we will endeavor to obtain
and maintain such insurance in coverage amounts which we deem adequate, any claim that may be brought against us could result in a court judgment or
settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance
policies also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts
awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be
able to obtain, sufficient capital to pay such amounts.

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

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

We  rely  significantly  on  information  technology  and  any  failure,  inadequacy,  interruption  or  security  lapse  of  that  technology,  including  any
cybersecurity incidents, could harm our ability to operate our business effectively.

Despite the implementation of security measures, our internal computer systems and those of third parties with which we contract are vulnerable
to  damage  from  cyber-attacks,  computer  viruses,  unauthorized  access,  natural  disasters,  terrorism,  war  and  telecommunication  and  electrical  failures.
System  failures,  accidents  or  security  breaches  could  cause  interruptions  in  our  operations,  and  could  result  in  a  material  disruption  of  our  product
development and clinical activities and business operations, in addition to possibly requiring substantial expenditures of resources to remedy. Cybersecurity
attacks in particular are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic
security breaches that could lead to disruptions in systems, misappropriation of our confidential or otherwise protected information and corruption of data.
The loss, theft or sabotage of product development or clinical trial data 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  and  our  development  programs  and  the
development of our product candidates could be delayed.

Sales of counterfeits of any of our product candidates, as well as unauthorized sales of any of our product candidates, may have adverse effects on our
revenues, business and results of operations and damage our brand and reputation.

Our  current  approved  products  or  our  new  product  candidates  may  become  subject  to  competition  from  counterfeit  pharmaceutical  products,
which are pharmaceutical products sold under the same or very similar brand names and/or having a similar appearance to genuine products, but which are
sold without proper licenses or approvals. Such products divert sales from genuine products, often are of lower cost, often are of lower quality (having
different ingredients or formulations, for example), and have the potential to damage the reputation for quality and effectiveness of the genuine product.
Obtaining regulatory approval for our product candidates is a complex and lengthy process. If during the period while the regulatory approval is pending,
illegal sales of counterfeit products begin, consumers may buy such counterfeit products, which could have an adverse impact on our revenues, business
and results of operations. In addition, if illegal sales of counterfeits result in adverse side effects to consumers, we may be associated with any negative
publicity resulting from such incidents. Although pharmaceutical regulation, control and enforcement systems throughout the world have been increasingly
active  in  policing  counterfeit  pharmaceuticals,  we  may  not  be  able  to  prevent  third  parties  from  manufacturing,  selling  or  purporting  to  sell  counterfeit
products competing with our current products or our new product candidates. Such sales may also be occurring without our knowledge. The existence and
any  increase  in  production  or  sales  of  counterfeit  products  or  unauthorized  sales  could  negatively  impact  our  revenues,  brand  reputation,  business  and
results of operations.

Risks Related to Product Development, Regulatory Approval, Manufacturing and Commercialization

We  depend  entirely  on  the  success  of  current  approved  products  and  our  new  product  candidates.  If  we  are  unable  to  generate  revenues  from  our
approved products and new product candidates, our ability to create stockholder value will be limited.

We have various product candidates under review with the FDA and are in the early stages of clinical development with a number of new product
candidates,  and  have  not  yet  generated  significant  revenues  from  our  approved  drug  products.  We  plan  on  submitting  our  clinical  trial  protocols  and
receiving approvals from the FDA and international regulatory authorities before we commence any clinical trials. We may not be successful in obtaining
acceptance from the FDA or comparable foreign regulatory authorities to start our clinical trials. If we do not obtain such acceptance, the time in which we
expect to commence clinical programs for any product candidate will be extended and such extension will increase our expenses and increase our need for
additional  capital.  Moreover,  there  is  no  guarantee  that  our  clinical  trials  will  be  successful  or  that  we  will  continue  clinical  development  in  support  of
additional product approvals from the FDA or comparable foreign regulatory authorities for any indication. We note that most product candidates never
reach the clinical development stage and even those that do commence clinical development have only a small chance of successfully completing clinical
development and gaining regulatory approval. Therefore, our business substantially depends entirely on the successful development, regulatory approval
and commercialization of our product candidates, which may never occur.

We face competition from other biotechnology and pharmaceutical companies and our operating results will suffer if we fail to compete effectively.

The  biotechnology  and  pharmaceutical  industries  are  intensely  competitive  and  subject  to  rapid  and  significant  technological  change.  We  have
existing competitors and potential new competitors in a number of jurisdictions, many of which have or will have substantially greater name recognition,
commercial infrastructures and financial, technical and personnel resources than we have. Established competitors may invest heavily to quickly discover
and  develop  novel  compounds  that  could  make  any  of  our  product  candidates  obsolete  or  uneconomical.  In  addition,  mergers  and  acquisitions  in  the
biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors, potentially
reducing or eliminating our commercial opportunity. Furthermore, such potential competitors may enter the market before us, and their products may be
designed to circumvent our pending patent applications and any patents we may receive. They may also challenge, narrow or invalidate any granted patents
or our patent applications, and such patents and patent applications may fail to provide adequate protection for our product candidates. Any new product
that  competes  with  an  approved  product  may  need  to  demonstrate  compelling  advantages  in  efficacy,  cost,  convenience,  tolerability  and  safety  to  be
commercially  successful.  Other  competitive  factors,  including  generic  competition,  could  force  us  to  lower  prices  or  could  result  in  reduced  sales.  In
addition, new products developed by others could emerge as competitors to our product candidates. If we are not able to compete effectively against our
current and future competitors, our business will not grow and our financial condition and operations will suffer.

We face substantial competition, which may result in others discovering, developing and commercializing products before or more successfully than
our product candidates.

The  development  and  commercialization  of  new  drugs  is  highly  competitive.  We  face  competition  (from  major  pharmaceutical  companies,
specialty  pharmaceutical  companies  and  biotechnology  companies  worldwide)  with  respect  to  our  current  product  candidates  and  will  face  competition
with respect to any product candidates that we may seek to develop or commercialize in the future. We compete directly with companies that focus on
505(b)(2)  and  generic  drugs,  and  companies  dedicating  their  resources  to  novel  forms  of  therapies  for  these  indications.  Many  of  these  competitors  are
attempting to develop products for our target indications. We face the risk that our competitors will develop a competing product using the same 505(b)(2)
pathway that we intend to pursue. Our business model is to focus on product candidates that we consider to have a shorter timeline to, and lower cost of,
regulatory approval. These attributes can also be taken advantage of by our competitors to develop and obtain marketing approval of a competing product.
In addition, following FDA approval of our product candidates for which we have no patent protection, our competitors may seek to develop a competing
product pursuant to the 505(j) pathway, which is an abbreviated pathway used for the regulatory approval of generic product candidates. As a result of the
foregoing, we may find that the market opportunity for our product candidates for which we have no patent protection is relatively small due to the fact that
barriers to entry are low and generic competition may follow within relatively short time periods after our product is approved. With the proliferation of
new drugs and therapies in these areas, we expect to face increasingly intense competition as new technologies become available. Any product candidates
that we successfully develop and commercialize will compete with existing products and new products that may become available in the future.

20

 
 
 
 
 
 
 
 
 
There are products already approved for all of the indications we are targeting. Many of these approved products are well established therapies and
are widely accepted by physicians, patients and third-party payors. This may make it difficult for us to achieve our business strategy of replacing existing
products with our product candidates. In addition, where we are able to offer benefits over existing products offered by our competitors, those competitors
may reformulate their drugs in a manner that mimics the benefits offered by our product candidates. As noted below, many of our product candidates are
not eligible for patent protection or the market and data exclusivity provisions under the Federal Food, Drug and Cosmetic Act (“FDCA”). Consequently,
our commercial operations face significant direct competition and our competitors may develop products that are similar to ours and perhaps safer, more
effective, more convenient or less costly than any that we are developing or that would render our product candidates obsolete or non-competitive. Our
inability to successfully compete could negatively impact our business, results of operations and stock price.

Our competitors may obtain FDA or other regulatory approval for comparable products more rapidly than we may obtain approval for ours, and the
risk of our competitors doing so may lead us to develop drug candidates without disclosing certain information with regard to such candidates.

The FDCA provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA, or supplement to an existing NDA or 505(b)(2) NDA if
new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to
the  approval  of  the  application,  (e.g.,  for  new  indications,  dosages,  strengths  or  dosage  forms  of  an  existing  drug).  Many  of  our  competitors  have
significantly  greater  financial,  manufacturing,  marketing,  drug  development,  technical  and  human  resources  than  we  do.  As  a  result,  many  of  our
competitors have the ability to bring a product candidate to market more rapidly than we can and depending on the nature of their product candidate they
could substantially delay the introduction of our product candidate into the market if their product qualifies for the market and data exclusivity provisions
under the FDCA. In order to preserve any competitive advantage, we will, at times, make the decision to pursue a product candidate for which we will not
disclose the API, dosage or reference drug until such time as we believe that any competitive advantage would not be materially compromised by public
disclosure of such information, which in some cases may be as late as our receipt of marketing approval from the FDA. Our business currently depends on
our  ability  to  bring  our  product  candidates  to  market  in  a  manner  that  preserves  our  perceived  competitive  advantage,  and  any  loss  of  that  competitive
advantage could negatively impact our business, results of operations and stock price.

If we are not able to obtain any required regulatory approvals for our product candidates, we will not be able to commercialize our product candidate
and our ability to generate revenue will be limited.

We may be required to successfully complete clinical trials for our product candidates before we can apply for marketing approval. Even if we
complete any such clinical trials, it does not assure marketing approval. Any such clinical trials may be unsuccessful, which would materially harm our
business. Even if such initial clinical trials are successful, we may be required to conduct additional clinical trials to establish our product candidates’ safety
and efficacy before an NDA or foreign equivalents can be submitted to the FDA or comparable foreign regulatory authorities for marketing approval of our
product candidates.

Our success depends on the receipt of regulatory approval and the issuance of such regulatory approvals is uncertain and subject to a number of

risks, including the following:

●

●

●

●

●

●

the results of any required toxicology studies may not support the submission of an IND for our product candidates;

the FDA or comparable foreign regulatory authorities or Institutional Review Boards (“IRB”), may disagree with the design or implementation
of our clinical trials;

we may not be able to provide acceptable evidence of our product candidates’ safety and efficacy;

the results of our clinical trials may not be satisfactory or may not meet the level of statistical or clinical significance required by the FDA or
other regulatory agencies for marketing approval;

the dosing of our product candidates in any required clinical trial may not be at an optimal level;

patients in our clinical trials may suffer adverse effects for reasons that may or may not be related to our product candidates;

●

the data collected from clinical trials may not be sufficient to support the submission of an NDA or other submission or to obtain regulatory
approval in the United States or elsewhere;

the  FDA  or  comparable  foreign  regulatory  authorities  may  fail  to  approve  the  manufacturing  processes  or  facilities  of  third-party
manufacturers with which we contract for clinical and commercial supplies; and

the approval policies or regulations of the FDA may significantly change in a manner rendering our clinical data insufficient for approval.

Failure to obtain regulatory approval for our product candidates for the foregoing, or any other reasons, will prevent us from commercializing our
product  candidates,  and  our  ability  to  generate  sufficient  revenue  will  be  materially  impaired.  We  cannot  guarantee  that  regulators  will  agree  with  our
assessment of the results of the clinical trials we intend to conduct in the future or that such trials will be successful. The FDA and other regulators have
substantial discretion in the approval process and may refuse to accept any application or may decide that our data is insufficient for approval and require
additional clinical trials, or pre-clinical or other studies. In addition, varying interpretations of the data obtained from pre-clinical and clinical testing could
delay, limit or prevent regulatory approval of our product candidates.

The process of obtaining regulatory approvals is expensive, often takes many years, if approval is obtained at all, and can vary substantially based
upon, among other things, the type, complexity and novelty of the product candidates involved, the jurisdiction in which regulatory approval is sought and
the substantial discretion of the regulatory authorities. Changes in regulatory approval policies during the development period, changes in or the enactment
of additional statutes or regulations, or changes in regulatory review for a submitted product application may cause delays in the approval or rejection of an
application.  Regulatory  approval  obtained  in  one  jurisdiction  does  not  necessarily  mean  that  a  product  candidate  will  receive  regulatory  approval  in  all
jurisdictions in which we may seek approval, but the failure to obtain approval in one jurisdiction may negatively impact our ability to seek approval in a
different  jurisdiction.  Failure  to  obtain  regulatory  marketing  approval  for  our  product  candidates  will  prevent  us  from  commercializing  the  product
candidate, and our ability to generate sufficient revenue will be materially impaired.

If  the  FDA  does  not  conclude  that  our  product  candidates  satisfy  the  requirements  for  the  505(b)(2)  regulatory  approval  pathway,  or  if  the
requirements  for  approval  of  any  of  our  product  candidates  under  Section  505(b)(2)  are  not  as  we  expect,  the  approval  pathway  for  our  product
candidates will likely take significantly longer, cost significantly more and encounter significantly greater complications and risks than anticipated, and
in any case may not be successful.

We  intend  to  seek  FDA  approval  through  the  505(b)(2)  regulatory  pathway  for  the  majority  of  our  product  candidates.  The  Drug  Price
Competition  and  Patent  Term  Restoration  Act  of  1984,  also  known  as  the  Hatch-Waxman  Act,  added  Section  505(b)(2)  to  the  Federal  Food,  Drug  and
Cosmetic Act (“FDCA”). Section 505(b)(2) permits the filing of an NDA where at least some of the information required for approval comes from studies
that were not conducted by or for the applicant. If the FDA does not allow us to pursue the 505(b)(2) regulatory pathway for our product candidates as
anticipated,  we  may  need  to  conduct  additional  clinical  trials,  provide  additional  data  and  information  and  meet  additional  standards  for  regulatory
approval.  If  this  were  to  occur,  the  time  and  financial  resources  required  to  obtain  FDA  approval  for  our  product  candidates  would  likely  substantially
increase. Moreover, the inability to pursue the 505(b)(2) regulatory pathway could result in new competitive products reaching the market faster than our
product  candidates,  which  could  materially  adversely  impact  our  competitive  position  and  prospects.  Even  if  we  are  allowed  to  pursue  the  505(b)(2)
regulatory  pathway  for  a  product  candidate,  we  cannot  assure  you  that  we  will  receive  the  requisite  or  timely  approvals  for  commercialization  of  such
product candidate. For example, we had under development a patented injectable pentoxifylline therapeutic candidate, which we believed would satisfy the
requirements  of  the  505(b)(2)  regulatory  pathway.  However,  based  on  a  pre-IND  meeting  with  the  FDA  in  March  2018  to  discuss  the  clinical  and
regulatory pathway for the product, we have decided to suspend all further development activities for this candidate indefinitely due to extraordinarily high
costs of the clinical trials that would be required by the FDA.

Notwithstanding  the  approval  of  many  products  by  the  FDA  pursuant  to  Section  505(b)(2),  over  the  last  few  years  some  pharmaceutical
companies  and  others  have  objected  to  the  FDA’s  interpretation  of  Section  505(b)(2)  to  allow  reliance  on  the  FDA’s  prior  findings  of  safety  and
effectiveness. If the FDA changes its interpretation of Section 505(b)(2), or if the FDA’s interpretation is successfully challenged in court, this could delay
or even prevent the FDA from approving any Section 505(b)(2) application that we submit. In addition, we expect that our competitors will file citizens’
petitions  with  the  FDA  in  an  attempt  to  persuade  the  FDA  that  our  product  candidate,  or  the  clinical  studies  that  support  their  approval,  contain
deficiencies. Such actions by our competitors could delay or even prevent the FDA from approving any NDA that we submit under Section 505(b)(2).

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Moreover, the FDA recently adopted an interpretation of the three-year exclusivity provisions whereby a 505(b)(2) application can be blocked by
exclusivity  even  if  does  not  rely  on  the  previously  approved  drug  that  has  exclusivity  (or  any  safety  or  effectiveness  information  regarding  that  drug).
Under the FDA’s new interpretation, approval may be blocked by exclusivity awarded to a previously-approved drug product that shares certain innovative
features with our product, even if our 505(b)(2) application does not identify the previously-approved drug product as a listed drug or rely upon any of its
safety  or  efficacy  data.  Any  failure  to  obtain  regulatory  approval  of  our  product  candidates  would  significantly  limit  our  ability  to  generate  sufficient
revenues, and any failure to obtain such approval for all of the indications and labeling claims we deem desirable could reduce our potential revenues.

An NDA submitted under Section 505(b)(2) subjects us to the risk that we may be subject to a patent infringement lawsuit that would delay or prevent
the review or approval of our product candidate.

The  505(b)(2)  application  would  enable  us  to  reference  published  literature  or  the  FDA’s  previous  findings  of  safety  and  effectiveness  for  the
branded reference drug. For NDAs submitted under Section 505(b)(2) of the FDCA, the patent certification and related provisions of the Hatch-Waxman
Act apply. In accordance with Hatch-Waxman Act, in seeking approval for a drug through such an NDA, applicants are required to list with the FDA each
patent whose claims cover the applicant’s product. Upon approval of a drug, each of the patents listed in the application for the drug is then published in the
FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Drugs listed in the Orange Book can, in
turn, be cited by potential generic competitors in support of approval of an ANDA. An ANDA provides for marketing of a drug product that has the same
active  ingredients  in  the  same  strengths  and  dosage  form  as  the  listed  drug  and  has  been  shown  to  be  bioequivalent  to  the  listed  drug.  Other  than  the
requirement for bioequivalence testing, ANDA applicants are not required to conduct, or submit results of, pre-clinical or clinical tests to prove the safety
or effectiveness of their drug product. Drugs approved in this way are commonly referred to as “generic equivalents” to the listed drug and can often be
substituted by pharmacists under prescriptions written for the original listed drug.

The  ANDA  applicant  is  required  to  certify  to  the  FDA  concerning  any  patents  listed  for  the  approved  product  in  the  FDA’s  Orange  Book.
Specifically, the applicant must certify that either: (i) the required patent information has not been filed; (ii) the listed patent has expired; (iii) the listed
patent has not expired, but will expire on a particular date and approval is sought after patent expiration or (iv) the listed patent is invalid or will not be
infringed by the new product. The ANDA applicant may also elect to submit a section viii statement certifying that its proposed ANDA label does not
contain (or carves out) any language regarding the patented method-of-use rather than certify to a listed method-of-use patent. If the applicant does not
challenge the listed patents, the ANDA application will not be approved until all the listed patents claiming the referenced product have expired.

A  certification  that  the  new  product  will  not  infringe  the  already  approved  product’s  listed  patents,  or  that  such  patents  are  invalid  or
unenforceable, is called a Paragraph IV certification. If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also
send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent
holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. Under the Hatch-Waxman Act, the holder
of patents that the 505 (b)(2) application references may file a patent infringement lawsuit after receiving notice of the Paragraph IV certification. Filing of
a  patent  infringement  lawsuit  against  the  filer  of  the  505(b)(2)  applicant  within  45  days  of  the  patent  owner’s  receipt  of  notice  triggers  a  one-time,
automatic, 30-month stay of the FDA’s ability to approve the 505(b)(2) NDA, unless patent litigation is resolved in favor of the Paragraph IV filer or the
patent expires before that time. Accordingly, we may invest a significant amount of time and expense in the development of one or more product candidates
only to be subject to significant delay and patent litigation before such product candidates may be commercialized, if at all.

In  addition,  a  505(b)(2)  application  will  not  be  approved  until  any  non-patent  exclusivity,  such  as  exclusivity  for  obtaining  approval  of  a  new
chemical entity listed in the Orange Book for the referenced product has expired. The FDA may also require us to perform one or more additional clinical
studies  or  measurements  to  support  the  change  from  the  branded  reference  drug,  which  could  be  time  consuming  and  could  substantially  delay  our
achievement of regulatory approvals for such product candidates. The FDA may also reject our future 505(b)(2) submissions and require us to file such
submissions under Section 505(b)(1) of the FDCA, which would require us to provide extensive data to establish safety and effectiveness of the drug for
the proposed use and could cause delay and be considerably more expensive and time consuming. These factors, among others, may limit our ability to
successfully commercialize our product candidates.

23

 
 
 
 
 
 
 
 
Companies that produce branded reference drugs routinely bring litigation against ANDA or 505(b)(2) applicants that seek regulatory approval to
manufacture and market generic and reformulated forms of their branded products. These companies often allege patent infringement or other violations of
intellectual property rights as the basis for filing suit against an ANDA or 505(b)(2) applicant. Likewise, patent holders may bring patent infringement suits
against  companies  that  are  currently  marketing  and  selling  their  approved  generic  or  reformulated  products.  Litigation  to  enforce  or  defend  intellectual
property rights is often complex and often involves significant expense and can delay or prevent introduction or sale of our product candidates. If patents
are held to be valid and infringed by our product candidates in a particular jurisdiction, we would, unless we could obtain a license from the patent holder,
be required to cease selling in that jurisdiction and may need to relinquish or destroy existing stock in that jurisdiction. There may also be situations where
we use our business judgment and decide to market and sell our approved products, notwithstanding the fact that allegations of patent infringement(s) have
not  been  finally  resolved  by  the  courts,  which  is  known  as  an  “at-risk  launch.”  The  risk  involved  in  doing  so  can  be  substantial  because  the  remedies
available to the owner of a patent for infringement may include, among other things, damages measured by the profits lost by the patent owner and not
necessarily by the profits earned by the infringer. In the case of a willful infringement, the definition of which is subjective, such damages may be increased
up  to  three  times.  Moreover,  because  of  the  discount  pricing  typically  involved  with  bioequivalent  and,  to  a  lesser  extent,  505(b)(2)  products,  patented
branded  products  generally  realize  a  substantially  higher  profit  margin  than  bioequivalent  and,  to  a  lesser  extent,  505(b)(2)  products,  resulting  in
disproportionate damages compared to any profits earned by the infringer. An adverse decision in patent litigation could have a material adverse effect on
our business, financial position and results of operations and could cause the market value of our common stock to decline.

Even if we receive regulatory approval for our additional product candidates, we may not be able to successfully commercialize these products, and the
revenue that we generate from those sales, if any, may be limited.

If  approved  for  marketing,  the  commercial  success  of  our  product  candidates  will  depend  upon  each  product’s  acceptance  by  the  medical
community, including physicians, patients and health care payors. The degree of market acceptance for any of our product candidates will depend on a
number of factors, including:

●

●

●

●

●

●

●

●

●

●

●

●

●

demonstration of clinical safety and efficacy;

relative convenience, dosing burden and ease of administration;

the prevalence and severity of any adverse effects;

the willingness of physicians to prescribe our product candidates, and the target patient population to try new therapies;

efficacy of our product candidates compared to competing products;

the introduction of any new products that may in the future become available targeting indications for which our product candidates may be
approved;

new procedures or therapies that may reduce the incidences of any of the indications in which our product candidates may show utility;

pricing and cost-effectiveness;

the inclusion or omission of our product candidates in applicable therapeutic and vaccine guidelines;

the effectiveness of our own or any future collaborators’ sales and marketing strategies;

limitations or warnings contained in approved labeling from regulatory authorities;

our  ability  to  obtain  and  maintain  sufficient  third-party  coverage  and  adequate  reimbursement  from  government  health  care  programs,
including  Medicare  and  Medicaid,  private  health  insurers  and  other  third-party  payors  or  to  receive  the  necessary  pricing  approvals  from
government bodies regulating the pricing and usage of therapeutics; and

the  willingness  of  patients  to  pay  out-of-pocket  in  the  absence  of  third-party  coverage  or  adequate  reimbursement  or  government  pricing
approvals.

If any of our product candidates are approved, but do not achieve an adequate level of acceptance by physicians, health care 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 product candidates may require significant resources and may never be successful.

In addition, even if we obtain regulatory approvals for our product candidates, the timing or scope of any approvals may prohibit or reduce our
ability to commercialize our product candidates successfully. For example, if the approval process takes too long, we may miss market opportunities and
give  other  companies  the  ability  to  develop  competing  products  or  establish  market  dominance.  Any  regulatory  approval  we  ultimately  obtain  may  be
limited  or  subject  to  restrictions  or  post-approval  commitments  that  render  our  product  candidates  not  commercially  viable.  For  example,  regulatory
authorities may approve any of our product candidates for fewer or more limited indications than we request, may not approve the price we intend to charge
for any of our product candidates, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve any of our
product  candidates  with  a  label  that  does  not  include  the  labeling  claims  necessary  or  desirable  for  the  successful  commercialization  of  that  indication.
Further, the FDA or comparable foreign regulatory authorities may place conditions on approvals or require risk management plans or a Risk Evaluation
and Mitigation Strategy (“REMS”), to assure the safe use of the drug. If the FDA concludes a REMS is needed, the FDA will not approve the NDA without
an  approved  REMS,  if  required.  A  REMS  could  include  medication  guides,  physician  communication  plans  or  elements  to  assure  safe  use,  such  as
restricted distribution methods, patient registries and other risk minimization tools. The FDA may also require a REMS for an approved product when new
safety  information  emerges.  Any  of  these  limitations  on  approval  or  marketing  could  restrict  the  commercial  promotion,  distribution,  prescription  or
dispensing of our product candidates. Moreover, product approvals may be withdrawn for non-compliance with regulatory standards or if problems occur
following the initial marketing of the product. Any of the foregoing scenarios could materially harm the commercial success of our product candidates.

We are subject to ongoing obligations and continued regulatory review, which may result in significant additional expense. Additionally, our product
candidates could be subject to labeling and other restrictions and withdrawal from the market, and we may be subject to penalties if we fail to comply
with regulatory requirements or if we experience unanticipated problems with our product candidates.

The FDA or foreign equivalent may still impose significant restrictions on our products indicated uses or the conditions of approval, or impose
ongoing  requirements  for  potentially  costly  and  time-consuming  post-approval  studies,  including  Phase  4  clinical  trials,  and  post-market  surveillance  to
monitor  safety  and  efficacy.  Our  product  candidates  will  also  be  subject  to  ongoing  regulatory  requirements  governing  the  manufacturing,  labeling,
packaging,  storage,  distribution,  safety  surveillance,  advertising,  promotion,  recordkeeping  and  reporting  of  adverse  events  and  other  post-market
information.  These  requirements  include  registration  with  the  FDA,  as  well  as  continued  compliance  with  current  Good  Clinical  Practices  regulations
(“cGCPs”)  for  any  clinical  trials  that  we  conduct  post-approval.  In  addition,  manufacturers  of  drug  products  and  their  facilities  are  subject  to  continual
review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP requirements relating to quality control, quality
assurance and corresponding maintenance of records and documents.

The FDA has the authority to require a REMS as part of an NDA or after approval, which may impose further requirements or restrictions on the
distribution  or  use  of  an  approved  drug,  such  as  limiting  prescribing  to  certain  physicians  or  medical  centers  that  have  undergone  specialized  training,
limiting treatment to patients who meet certain safe-use criteria or requiring patient testing, monitoring and/or enrollment in a registry.

With respect to sales and marketing activities by us or any future partner, advertising and promotional materials must comply with FDA rules in
addition to other applicable federal, state and local laws in the United States and similar legal requirements in other countries. In the United States, the
distribution of product samples to physicians must comply with the requirements of the U.S. Prescription Drug Marketing Act. Application holders must
obtain FDA approval for product and manufacturing changes, depending on the nature of the change. We may also be subject, directly or indirectly through
our  customers  and  partners,  to  various  fraud  and  abuse  laws,  including,  without  limitation,  the  U.S.  Anti-Kickback  Statute,  U.S.  False  Claims  Act,  and
similar state laws, which impact, among other things, our proposed sales, marketing and scientific/educational grant programs. If we participate in the U.S.
Medicaid Drug Rebate Program, the Federal Supply Schedule of the U.S. Department of Veterans Affairs, or other government drug programs, we will be
subject to complex laws and regulations regarding reporting and payment obligations. All of these activities are also potentially subject to U.S. federal and
state consumer protection and unfair competition laws. Similar requirements exist in many of these areas in other countries.

25

 
 
 
 
 
 
 
 
In addition, if any of our product candidates are approved for a particular indication, our product labeling, advertising and promotion would be
subject  to  regulatory  requirements  and  continuing  regulatory  review.  The  FDA  strictly  regulates  the  promotional  claims  that  may  be  made  about
prescription  products.  In  particular,  a  product  may  not  be  promoted  for  uses  that  are  not  approved  by  the  FDA  as  reflected  in  the  product’s  approved
labeling. However, companies may share truthful and not misleading information that is otherwise consistent with the product’s approved FDA labeling. If
we receive marketing approval for our product candidates, physicians may nevertheless legally prescribe our products to their patients in a manner that is
inconsistent with the approved label. If we are found to have promoted such off-label uses, we may become subject to significant liability and government
fines. 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 sanctions. The federal government has levied large civil and criminal fines against
companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that
companies enter into consent decrees of permanent injunctions under which specified promotional conduct is changed or curtailed.

If  we  or  a  regulatory  agency  discovers  previously  unknown  problems  with  a  product,  such  as  adverse  events  of  unanticipated  severity  or
frequency,  problems  with  the  facility  where  the  product  is  manufactured,  or  we  or  our  manufacturers  fail  to  comply  with  applicable  regulatory
requirements, we may be subject to the following administrative or judicial sanctions:

●

●

●

●

●

●

●

●

●

restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market, or voluntary or mandatory product
recalls;

issuance of warning letters or untitled letters;

clinical holds;

injunctions or the imposition of civil or criminal penalties or monetary fines;

suspension or withdrawal of regulatory approval;

suspension of any ongoing clinical trials;

refusal to approve pending applications or supplements to approved applications filed by us, or suspension or revocation of product license
approvals;

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

product seizure or detention or refusal to permit the import or export of product.

The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue.

Adverse regulatory action, whether pre- or post-approval, can also potentially lead to product liability claims and increase our product liability exposure.

Obtaining  foreign  regulatory  approvals  and  compliance  with  foreign  regulatory  requirements  could  result  in  significant  delays,  difficulties  and
costs  for  us  and  could  delay  or  prevent  the  introduction  of  our  products  in  certain  countries.  If  we  fail  to  comply  with  the  regulatory  requirements  in
international markets and/or to receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential
of our product candidates will be harmed.

Significant additional labeling or warning requirements or limitations on the availability of our products may inhibit sales of affected products.

Various jurisdictions may seek to adopt significant additional product labeling or warning requirements or limitations on the availability of our
products relating to the content or perceived adverse health consequences of our products. Federal laws may preempt some or all of these attempts by state
or localities to impose additional labeling or warning requirements. If these types of requirements become applicable to our products under current or future
environmental or health laws or regulations, they may inhibit sales of our products. Moreover, if we fail to meet compliance deadlines for any such new
requirements,  our  products  may  be  deemed  misbranded  or  mislabeled  and  could  be  subject  to  enforcement  action,  or  we  could  be  exposed  to  private
lawsuits alleging misleading labels or product promotion.

Current and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates
and affect the prices we may obtain.

In  the  United  States  and  some  foreign  jurisdictions,  there  have  been  a  number  of  legislative  and  regulatory  changes  and  proposed  changes
regarding the health care system that could prevent or delay marketing approval for our product candidates, restrict or regulate post-approval activities and
affect our ability to profitably sell our product candidates. Legislative and regulatory proposals have been made to expand post-approval requirements and
restrict sales and promotional activities for pharmaceutical products. We do not know whether additional legislative changes will be enacted, or whether the
FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if
any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as
well as subject us to more stringent product labeling and post-marketing testing and other requirements.

In the United States, the Medicare Modernization Act (“MMA”) changed the way Medicare covers and pays for pharmaceutical products. The
legislation expanded Medicare coverage for drug purchases by the elderly and introduced a new reimbursement methodology based on average sales prices
for drugs. In addition, this legislation authorized Medicare Part D prescription drug plans to use formularies where they can limit the number of drugs that
will be covered in any therapeutic class. As a result of this legislation and the expansion of federal coverage of drug products, we expect that there will be
additional pressure to contain and reduce costs. These cost reduction initiatives and other provisions of this legislation could decrease the coverage and
price  that  we  receive  for  our  product  candidates  and  could  seriously  harm  our  business.  While  the  MMA  applies  only  to  drug  benefits  for  Medicare
beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates, and any reduction in
reimbursement that results from the MMA may result in a similar reduction in payments from private payors.

In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, collectively
referred to as the Health Care Reform Law, was enacted, which substantially changes the way health care is financed by both governmental and private
insurers, and significantly impacts the U.S. pharmaceutical industry. The Health Care Reform Law, among other things, imposed reporting requirements on
manufacturers related to drug samples and financial relationships with physicians and teaching hospitals, increased the minimum Medicaid rebates owed by
manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations,
established annual fees on manufacturers of certain branded prescription drugs, and established a Medicare Part D coverage gap discount program.

Some of the provisions of the Health Care Reform Law have yet to be implemented, and there have been judicial and Congressional challenges to
certain aspects of the Health Care Reform Law, as well as recent efforts by the Trump administration to repeal or replace certain aspects of the Health Care
Reform Law. Since January 2017, former President Trump had signed two executive orders and other directives designed to delay, circumvent or loosen
certain requirements mandated by the Health Care Reform Law. Concurrently, Congress has considered legislation that would repeal or repeal and replace
all  or  part  of  the  Health  Care  Reform  Law.  While  Congress  has  not  passed  comprehensive  repeal  legislation,  two  bills  affecting  the  implementation  of
certain taxes under the Health Care Reform Law have been signed into law. The Tax Act included a provision which repealed, effective January 1, 2019,
the  tax-based  shared  responsibility  payment  imposed  by  the  Health  Care  Reform  Law  on  certain  individuals  who  fail  to  maintain  qualifying  health
coverage  for  all  or  part  of  a  year  that  is  commonly  referred  to  as  the  “individual  mandate.”  On  January  22,  2018,  former  President  Trump  signed  a
continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain Health Care Reform Law-mandated fees, including
the so-called “Cadillac” tax on certain high-cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based
on market share, and the medical device excise tax on non-exempt medical devices. The Bipartisan Budget Act of 2018, among other things, amended the
Health Care Reform, effective January 1, 2019, to increase from 50% to 70% the point-of-sale discount that is owed by pharmaceutical manufacturers who
participate in Medicare Part D and to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. On December 14,
2018, a Texas U.S. District Court Judge ruled that the Health Care Reform is unconstitutional in its entirety because the “individual mandate” was repealed
by Congress as part of the Tax Act. While the Texas U.S. District Court Judge, as well as the Trump administration and CMS, have stated that the ruling
will have no immediate effect pending appeal of the decision, it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the
Health  Care  Reform  will  impact  the  ACA  and  our  business.  We  cannot  predict  the  impact  on  our  business  of  changes  to  current  laws  and  regulations.
However, any changes that lower reimbursements for products for which we may obtain regulatory approval, or that impose administrative and financial
burdens on us, could adversely affect our business.

27

 
 
 
 
 
 
 
In addition, other legislative changes have been proposed and adopted in the United States since the Health Care Reform Law was enacted. These
changes include, among others, aggregate reductions of Medicare payments to providers of up to 2% per fiscal year. We expect that additional state and
federal health care reform measures will be adopted in the future, which may alter or completely replace the existing health care financing structure. Any of
these  reform  measures  could  limit  the  amounts  that  federal  and  state  governments  will  pay  for  health  care  products  and  services,  which  could  result  in
reduced demand for any such product candidate that we may have developed or additional pricing pressures on our business.

Further,  there  has  been  heightened  governmental  scrutiny  in  the  United  States  of  pharmaceutical  pricing  practices  in  light  of  the  rising  cost  of
prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation
designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs,
and reform government program reimbursement methodologies for products. For example, the Trump administration released a “Blueprint” to lower drug
prices and reduce out of pocket costs of drugs that contains additional proposals to increase drug manufacturer competition, increase the negotiating power
of  certain  federal  healthcare  programs,  incentivize  manufacturers  to  lower  the  list  price  of  their  products,  and  reduce  the  out-of-pocket  costs  of  drug
products  paid  by  consumers.  On  January  31,  2019,  the  U.S.  Department  of  Health  and  Human  Services,  Office  of  Inspector  General,  proposed
modifications to the federal Anti-Kickback Statute discount safe harbor for the purpose of reducing the cost of drug products to consumers which, among
other things, if finalized, will affect discounts paid by manufacturers to Medicare Part D plans, Medicaid managed care organizations and pharmacy benefit
managers working with these organizations. While some of these and other proposed measures may require additional authorization to become effective,
Congress  and  government  administration  officials  have  each  indicated  that  they  will  continue  to  seek  new  legislative  and/or  administrative  measures  to
control drug costs.

The policies of the FDA or similar regulatory authorities may change, and additional government regulations may be enacted that could prevent,
limit or delay regulatory approval of our product candidates. For example, in December 2016, the 21st Century Cures Act was signed into law. The 21st
Century Cures Act, among other things, is intended to modernize the regulation of drugs and biologics and spur innovation, but it has not yet been fully
implemented and its ultimate implementation is unclear. Furthermore, the Trump administration has taken several executive actions, including the issuance
of a number of executive orders, that could impose significant burdens on, or otherwise materially delay, the FDA’s ability to engage in routine regulatory
and  oversight  activities  such  as  implementing  statutes  through  rulemaking,  issuance  of  guidance  and  review  and  approval  of  marketing  applications.  If
these executive actions impose constraints on the FDA’s ability to engage in oversight and implementation activities in the normal course, our business may
be negatively impacted. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are
not able to maintain regulatory compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve
or sustain profitability, which would adversely affect our business.

If we market our existing approved products or any of our new product candidates in a manner that violates health care fraud and abuse laws, or if we
violate government price reporting laws, we may be subject to civil or criminal penalties.

The FDA enforces laws and regulations, which require that the promotion of pharmaceutical products be consistent with the approved prescribing
information. While physicians may prescribe an approved product for a so-called “off label” use, it is unlawful for a pharmaceutical company to promote
its products in a manner that is inconsistent with its approved label and any company which engages in such conduct can be subject to significant liability.
Similarly,  industry  codes  in  the  EU  and  other  foreign  jurisdictions  prohibit  companies  from  engaging  in  off-label  promotion  and  regulatory  agencies  in
various countries enforce violations of the code with civil penalties. While we intend to ensure that our promotional materials are consistent with our label,
regulatory agencies may disagree with our assessment and may issue untitled letters, warning letters or may institute other civil or criminal enforcement
proceedings. In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal health care fraud and abuse
laws have been applied in recent years to restrict certain marketing practices in the pharmaceutical industry. These laws include, among others, the U.S.
Anti-Kickback Statute, U.S. False Claims Act and similar state laws. Because of the breadth of these laws and the narrowness of their exceptions and safe
harbors, it is possible that some of our business activities could be subject to challenge under one or more of these laws.

28

 
 
 
 
 
 
 
The U.S. Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to
induce, or in return for, purchasing, leasing, ordering or arranging for the purchase, lease or order of any health care item or service reimbursable under
Medicare,  Medicaid  or  other  federally  financed  health  care  programs.  This  statute  has  been  interpreted  broadly  to  apply  to  arrangements  between
pharmaceutical manufacturers on the one hand and prescribers, purchasers, formulary managers, and others on the other hand. Although there are several
statutory  exceptions  and  regulatory  safe  harbors  protecting  certain  common  activities  from  prosecution,  the  exceptions  and  safe  harbors  are  drawn
narrowly, and practices that involve remuneration intended to induce prescribing, purchasing or recommending may be subject to scrutiny if they do not
qualify for an exception or safe harbor. Our practices may not, in all cases, meet all of the criteria for safe harbor protection from anti-kickback liability.
Moreover, recent health care reform legislation has strengthened these laws. For example, the Health Care Reform Law, among other things, amended the
intent  requirement  of  the  U.S.  Anti-Kickback  Statute  and  other  criminal  health  care  fraud  statutes;  a  person  or  entity  no  longer  needs  to  have  actual
knowledge of the statutes or specific intent to violate them in order to have committed a violation. In addition, the Health Care Reform Law provides that
the  government  may  assert  that  a  claim  including  items  or  services  resulting  from  a  violation  of  the  U.S.  Anti-Kickback  Statute  constitutes  a  false  or
fraudulent claim for purposes of the U.S. False Claims Act. Federal false claims laws prohibit any person from knowingly presenting, or causing to be
presented, a false claim for payment to the federal government or knowingly making, or causing to be made, a false statement to get a false claim paid.

Over the past few years, several pharmaceutical and other health care companies have been prosecuted under these laws for a variety of alleged
promotional and marketing activities, such as: allegedly providing free trips, free goods, sham consulting fees and grants and other monetary benefits to
prescribers; reporting to pricing services inflated average wholesale prices that were then used by federal programs to set reimbursement rates; engaging in
off-label  promotion  that  caused  claims  to  be  submitted  to  Medicare  or  Medicaid  for  non-covered,  off-label  uses;  and  submitting  inflated  best  price
information to the Medicaid Rebate Program to reduce liability for Medicaid rebates. Most states also have statutes or regulations similar to the U.S. Anti-
Kickback Statute and the U.S. False Claims Act, which apply to items and services reimbursed under Medicaid and other state programs, or, in several
states,  apply  regardless  of  the  payor.  Sanctions  under  these  federal  and  state  laws  may  include  significant  administrative,  criminal,  and  civil  monetary
penalties, exclusion of a manufacturer’s products from reimbursement under government programs, fines and imprisonment.

We are completely dependent on third parties to manufacture our approved products and new product candidates, and our commercialization of our
product  candidates  could  be  halted,  delayed  or  made  less  profitable  if  those  third  parties  fail  to  obtain  manufacturing  approval  from  the  FDA  or
comparable foreign regulatory authorities, fail to provide us with sufficient quantities of our product candidates or fail to do so at acceptable quality
levels or prices.

We do not currently have, nor do we plan to acquire, the capability or infrastructure to manufacture the active pharmaceutical ingredient (“API”)
in our product candidates for use in our clinical trials or for commercial product, if any. In addition, we do not have the capability to encapsulate any of our
product candidates as a finished drug product for commercial distribution. As a result, we will be obligated to rely on contract manufacturers, if and when
any of our product candidates are approved for commercialization. While we have entered into certain agreements with contract manufacturers for clinical
and commercial supply, there can be no assurance we will be able to maintain those relationships or engage additional contract manufacturers for clinical or
commercial supply of any of our product candidates on favorable terms to us, or at all.

The  facilities  used  by  our  contract  manufacturers  to  manufacture  our  product  candidates  must  be  approved  by  the  FDA  or  comparable  foreign
regulatory authorities pursuant to inspections that will be conducted after we submit an NDA to the FDA or their equivalents to other relevant regulatory
authorities. We will not control the manufacturing process of, and will be completely dependent on, our contract manufacturing partners for compliance
with cGMPs for manufacture of both active drug substances and finished drug products. These cGMP regulations cover all aspects of the manufacturing,
testing, quality control and record keeping relating to our product candidates. If our contract manufacturers do not successfully manufacture material that
conforms to our specifications and the strict regulatory requirements of the FDA or others, they will not be able to secure or maintain regulatory approval
for  their  manufacturing  facilities.  If  the  FDA  or  a  comparable  foreign  regulatory  authority  does  not  approve  these  facilities  for  the  manufacture  of  our
product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly
impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved.

Our contract manufacturers will be subject to ongoing periodic unannounced inspections by the FDA and corresponding state and foreign agencies
for  compliance  with  cGMPs  and  similar  regulatory  requirements.  We  will  not  have  control  over  our  contract  manufacturers’  compliance  with  these
regulations and standards. Failure by any of our contract manufacturers to comply with applicable regulations could result in sanctions being imposed on
us, including fines, injunctions, civil penalties, failure to grant approval to market any of our product candidates, delays, suspensions or withdrawals of
approvals, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect our business. In addition, we will not have
control  over  the  ability  of  our  contract  manufacturers  to  maintain  adequate  quality  control,  quality  assurance  and  qualified  personnel.  Failure  by  our
contract manufacturers to comply with or maintain any of these standards could adversely affect our ability to develop, obtain regulatory approval for or
market any of our product candidates.

29

 
 
 
 
 
 
 
 
If, for any reason, these third parties are unable or unwilling to perform, we may not be able to terminate our agreements with them, and we may
not be able to locate alternative manufacturers or formulators or enter into favorable agreements with them and we cannot be certain that any such third
parties will have the manufacturing capacity to meet future requirements. If these manufacturers or any alternate manufacturer of finished drug product
experiences any significant difficulties in its respective manufacturing processes for our API or finished products or should cease doing business with us,
we could experience significant interruptions in the supply of any of our product candidates or may not be able to create a supply of our product candidates
at all. Were we to encounter manufacturing issues, our ability to produce a sufficient supply of any of our product candidates might be negatively affected.
Our inability to coordinate the efforts of our third-party manufacturing partners, or the lack of capacity available at our third-party manufacturing partners,
could impair our ability to supply any of our product candidates at required levels. Because of the significant regulatory requirements that we would need
to satisfy in order to qualify a new bulk or finished product manufacturer, if we face these or other difficulties with our current manufacturing partners, we
could experience significant interruptions in the supply of any of our product candidates if we decided to transfer the manufacture of any of our product
candidates to one or more alternative manufacturers in an effort to deal with the difficulties.

Any manufacturing problem or the loss of a contract manufacturer could be disruptive to our operations and result in lost sales. Additionally, we
rely  on  third  parties  to  supply  the  raw  materials  needed  to  manufacture  our  potential  products.  Any  reliance  on  suppliers  may  involve  several  risks,
including  a  potential  inability  to  obtain  critical  materials  and  reduced  control  over  production  costs,  delivery  schedules,  reliability  and  quality.  Any
unanticipated disruption to a contract manufacturer caused by problems at suppliers could delay shipment of Biorphen or any of our product candidates,
increase our cost of goods sold and result in lost sales.

We cannot guarantee that our future manufacturing and supply partners will be able to reduce the costs of commercial scale manufacturing of any
of our product candidates over time. If the commercial-scale manufacturing costs of any of our product candidates are higher than expected, these costs
may significantly impact our operating results. In order to reduce costs, we may need to develop and implement process improvements. However, in order
to do so, we will need, from time to time, to notify or make submissions with regulatory authorities, and the improvements may be subject to approval by
such regulatory authorities. We cannot be sure that we will receive these necessary approvals or that these approvals will be granted in a timely fashion. We
also cannot guarantee that we will be able to enhance and optimize output in our commercial manufacturing process. If we cannot enhance and optimize
output, we may not be able to reduce our costs over time.

We may not be able to establish agreements with third parties with whom we wish to collaborate and, if we are able to establish them, we may not be
able to establish them on commercially reasonable terms, which could result in alterations or delays of our development and commercialization plans.

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

Agreements with third parties are complex and time-consuming to negotiate and document. In addition, there have been a significant number of
recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future third parties to assist us in
our business operations. We may not be able to negotiate agreements on a timely basis, on acceptable terms or at all. If we are unable to do so, we may
have  to  curtail  the  development  of  the  product  candidate,  reduce  or  delay  its  development  program,  delay  its  potential  commercialization  or  reduce  the
scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If
we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may
not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidate or bring
it to market and generate product revenue.

30

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

We may need to rely on third parties to conduct clinical trials for our future product candidates. If these third parties do not successfully carry out their
contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize any of our product candidates
and our business would be substantially harmed.

We have entered into agreements with third-party CROs to conduct and manage our clinical programs including contracting with clinical sites to
perform  our  clinical  studies.  We  plan  to  rely  heavily  on  these  parties  for  execution  of  clinical  studies  for  our  product  candidates  and  will  control  only
certain aspects of their activities. Nevertheless, we will be responsible for ensuring that each of our studies is conducted in accordance with the applicable
protocol, legal, regulatory and scientific standards, and our reliance on CROs and clinical sites will not relieve us of our regulatory responsibilities. We and
our CROs will be required to comply with cGCPs, which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities
for  any  products  in  clinical  development.  The  FDA  and  its  foreign  equivalents  enforce  these  cGCP  regulations  through  periodic  inspections  of  trial
sponsors, principal investigators and trial sites. If we or our CROs fail to comply with applicable cGCPs, the clinical data generated in our clinical trials
may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving
our marketing applications. We cannot assure you that, upon inspection, the FDA or other regulatory authorities will determine that any of our clinical trials
comply with cGCPs. In addition, our clinical trials must be conducted with products produced under cGMP regulations and will require a large number of
test subjects. Our failure or the failure of our CROs or clinical sites to comply with these regulations may require us to repeat clinical trials, which would
delay the regulatory approval process and could also subject us to enforcement action up to and including civil and criminal penalties.

Although we intend to design the clinical trials for our product candidates in consultation with CROs, we expect that the CROs will manage all of
the clinical trials conducted at contracted clinical sites. As a result, many important aspects of our drug development programs would be outside of our
direct control. In addition, the CROs and clinical sites may not perform all of their obligations under arrangements with us or in compliance with regulatory
requirements.  If  the  CROs  or  clinical  sites  do  not  perform  clinical  trials  in  a  satisfactory  manner,  breach  their  obligations  to  us  or  fail  to  comply  with
regulatory  requirements,  the  development  and  commercialization  of  any  of  our  product  candidates  for  the  subject  indication  may  be  delayed  or  our
development program materially and irreversibly harmed. We cannot control the amount and timing of resources these CROs and clinical sites will devote
to our program or any of our product candidates. If we are unable to rely on clinical data collected by our CROs, we could be required to repeat, extend the
duration of, or increase the size of our clinical trials, which could significantly delay commercialization and require significantly greater expenditures.

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

We enter into various contracts in the normal course of our business, some or all of which may require us to indemnify the other party to the contract.
In the event we have to perform under these indemnification provisions, it could have an adverse effect on our business, financial condition and results
of operations.

In the normal course of business, we periodically may enter into commercial, service, collaboration, licensing, consulting and other agreements
that contain indemnification provisions. With respect to our commercial agreements, vendors typically ask for indemnification from any third-party product
liability  claims  that  could  result  from  the  production,  use  or  consumption  of  the  product,  as  well  as  for  alleged  infringements  of  any  patent  or  other
intellectual property right by a third party. Should our obligation under an indemnification provision exceed applicable insurance coverage or if we were
denied insurance coverage, our business, financial condition and results of operations could be adversely affected. Similarly, if we are relying on a third
party to indemnify us and the party is denied insurance coverage, or the indemnification obligation exceeds the applicable insurance coverage and does not
have other assets available to indemnify us, our business, financial condition and results of operations could be adversely affected.

31

 
 
 
 
 
 
 
 
 
Any termination or suspension of, or delays in the commencement or completion of, any necessary studies of any of our product candidates for any
indications could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.

The commencement and completion of clinical studies can be delayed for a number of reasons, including delays related to:

● the FDA or a comparable foreign regulatory authority failing to grant permission to proceed and placing the clinical study on hold;

● subjects for clinical testing failing to enroll or remain in our trials at the rate we expect;

● a facility manufacturing any of our product candidates being ordered by the FDA or other government or regulatory authorities to temporarily
or  permanently  shut  down  due  to  violations  of  cGMP  requirements  or  other  applicable  requirements,  or  cross-contaminations  of  product
candidates in the manufacturing process;

● any changes to our manufacturing process that may be necessary or desired;

● subjects  choosing  an  alternative  treatment  for  the  indications  for  which  we  are  developing  our  product  candidates,  or  participating  in

competing clinical studies;

● subjects experiencing severe or unexpected drug-related adverse effects;

● reports from clinical testing on similar technologies and products raising safety and/or efficacy concerns;

● third-party clinical investigators losing their license or permits necessary to perform our clinical trials, not performing our clinical trials on our
anticipated  schedule  or  employing  methods  consistent  with  the  clinical  trial  protocol,  cGMP  requirements,  or  other  third  parties  not
performing data collection and analysis in a timely or accurate manner;

● inspections of clinical study sites by the FDA, comparable foreign regulatory authorities, or IRBs finding regulatory violations that require us
to undertake corrective action, result in suspension or termination of one or more sites or the imposition of a clinical hold on the entire study,
or that prohibit us from using some or all of the data in support of our marketing applications;

● third-party contractors becoming debarred or suspended or otherwise penalized by the FDA or other government or regulatory authorities for
violations of regulatory requirements, in which case we may need to find a substitute contractor, and we may not be able to use some or any
of the data produced by such contractors in support of our marketing applications;

● one or  more  IRBs  refusing  to  approve,  suspending  or  terminating  the  study  at  an  investigational  site,  precluding  enrollment  of  additional
subjects, or withdrawing its approval of the trial; reaching agreement on acceptable terms with prospective CROs and clinical trial sites, the
terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

● deviations of the clinical sites from trial protocols or dropping out of a trial;

● adding new clinical trial sites;

● the inability of the CRO to execute any clinical trials for any reason; and

● government or regulatory delays or “clinical holds” requiring suspension or termination of a trial.

Product development costs for any of our product candidates will increase if we have delays in testing or approval or if we need to perform more
or larger clinical studies than planned. Additionally, changes in regulatory requirements and policies may occur and we may need to amend study protocols
to reflect these changes. Amendments may require us to resubmit our study protocols to the FDA, comparable foreign regulatory authorities, and IRBs for
reexamination, which may impact the costs, timing or successful completion of that study. If we experience delays in completion of, or if we, the FDA or
other regulatory authorities, the IRB, or other reviewing entities, or any of our clinical study sites suspend or terminate any of our clinical studies of any of
our product candidates, its commercial prospects may be materially harmed and our ability to generate sufficient product revenues will be delayed. Any
delays in completing our clinical trials will increase our costs, slow down our development and approval process and jeopardize our ability to generate
sufficient revenues. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, many of the factors that
cause, or lead to, termination or suspension of, or a delay in the commencement or completion of, clinical studies may also ultimately lead to the denial of
regulatory approval of our product candidates. In addition, if one or more clinical studies are delayed, our competitors may be able to bring products to
market before we do, and the commercial viability of any of our product candidates could be significantly reduced.

Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be
predictive of future trial results.

Clinical testing of drug product candidates is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can
occur at any time during the clinical trial process. The results of pre-clinical studies and early clinical trials may not be predictive of the results of later-
stage clinical trials. We cannot assure you that the FDA or comparable foreign regulatory authorities will view the results as we do or that any future trials
of any of our product candidates will achieve positive results. Product candidates in later stages of clinical trials may fail to show the desired safety and
efficacy traits despite having progressed through pre-clinical studies and initial clinical trials. A number of companies in the biopharmaceutical industry
have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier
trials. Any future clinical trial results for our product candidates may not be successful.

In addition, a number of factors could contribute to a lack of favorable safety and efficacy results for any of our product candidates. For example,
such  trials  could  result  in  increased  variability  due  to  varying  site  characteristics,  such  as  local  standards  of  care,  differences  in  evaluation  period  and
surgical technique, and due to varying patient characteristics including demographic factors and health status.

We may need to conduct clinical trials for our new product candidates and we may be delayed in commercializing or fail to find success in these
trials. Further, the results of any clinical trial may not be predictive of future trial results. Positive results in preclinical testing and early clinical trials do not
ensure that later clinical trials will be successful. A number of pharmaceutical companies have suffered significant setbacks in clinical trials, including in
Phase 3, after promising results in preclinical testing and early clinical trials. These setbacks have included negative safety and efficacy observations in
later clinical trials, including previously unreported adverse events.

Phase 3 clinical trials often produce unsatisfactory results even though prior clinical trials were successful. Moreover, the results of clinical trials
may be unsatisfactory to the FDA or foreign regulatory authorities even if we believe those clinical trials to be successful. The FDA or applicable foreign
regulatory agencies may suspend one or all of our clinical trials or require that we conduct additional clinical, nonclinical, manufacturing, validation or
drug product quality studies and submit that data before considering or reconsidering any NDA or similar foreign regulatory application we may submit.
Depending on the extent of these additional studies, approval of any applications that we submit may be significantly delayed or may require us to expend
more resources than we have available. It is also possible that additional studies we conduct may not be considered sufficient by the FDA or applicable
foreign regulatory agencies to provide regulatory approval.

If any of these outcomes occur, we may not receive approval for our product candidate.

33

 
 
 
 
 
 
 
 
 
Third-party coverage and reimbursement and health care cost containment initiatives and treatment guidelines may constrain our future revenues.

Our  ability  to  successfully  market  Biorphen  and  our  product  candidates  will  depend  in  part  on  the  coverage  and  level  of  reimbursement  that
government  health  administration  authorities,  private  health  coverage  insurers  and  other  organizations  provide  for  the  cost  of  our  products  and  related
treatments. Countries in which any of our product candidates are sold through reimbursement schemes under national health insurance programs frequently
require  that  manufacturers  and  sellers  of  pharmaceutical  products  obtain  governmental  approval  of  initial  prices  and  any  subsequent  price  increases.  In
certain  countries,  including  the  United  States,  government-funded  and  private  medical  care  plans  can  exert  significant  indirect  pressure  on  prices.
Increasingly, third-party payors attempt to contain health care costs in ways that are likely to impact our development of products, including:

● failing to approve or challenging the prices charged for health care products;

● introducing reimportation schemes from lower priced jurisdictions;

● limiting both coverage and the amount of reimbursement for new therapeutic products;

● denying  or  limiting  coverage  for  products  that  are  approved  by  the  regulatory  agencies  but  are  considered  to  be  experimental  or

investigational by third-party payors; and

● refusing to provide coverage when an approved product is used in a way that has not received regulatory marketing approval.

We may not be able to sell Biorphen or our product candidates profitably if adequate prices are not approved or coverage and reimbursement is

unavailable or limited in scope.

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.

We are subject to laws and regulations governing data privacy and the protection of personal information. These laws and regulations govern our
processing  of  personal  data,  including  the  collection,  access,  use,  analysis,  modification,  storage,  transfer,  security  breach  notification,  destruction  and
disposal of personal data. There are foreign and state law versions of these laws and regulations to which we are currently and/or may in the future, be
subject. For example, the collection and use of personal health data in the European Union is governed by the GDPR. The GDPR, which is wide-ranging in
scope,  imposes  several  requirements  relating  to  the  consent  of  the  individuals  to  whom  the  personal  data  relates,  the  information  provided  to  the
individuals,  the  security  and  confidentiality  of  the  personal  data,  data  breach  notification  and  the  use  of  third-party  processors  in  connection  with  the
processing of personal data. The GDPR also imposes strict rules on the transfer of personal data out of the European Union to the United States, provides
an enforcement authority and imposes large monetary penalties for noncompliance. The GDPR requirements apply not only to third-party transactions, but
also  to  transfers  of  information  within  our  company,  including  employee  information.  In  addition,  in  2018  California  adopted  a  new  privacy  law  that
became  effective  on  January  1,  2020,  which  borrows  heavily  from  the  GDPR.  The  GDPR  and  similar  data  privacy  laws  of  other  jurisdictions  place
significant responsibilities on us and create potential liability in relation to personal data that we or our third-party service providers process, including in
clinical trials conducted in the United States and the European Union. In addition, we expect that there will continue to be new proposed laws, regulations
and industry standards relating to privacy and data protection in the United States, the European Union and other jurisdictions, and we cannot determine the
impact such future laws, regulations and standards may have on our business.

Risks Relating to Our Intellectual Property Rights

We  will  depend  on  rights  to  certain  pharmaceutical  compounds  that  have  been  acquired  by  us.  We  do  not  have  complete  control  over  these
pharmaceutical compounds and any loss of our rights to them could prevent us from selling our products.

We  are  dependent  on  the  assignment  and  licensing  from  third  parties  for  certain  of  our  pharmaceutical  compounds  and  potential  product
candidates. Our rights to use the pharmaceutical compounds we were assigned are subject to the negotiation of, continuation of and compliance with the
terms of those assignments and licenses. Moreover, under these agreements, any related patents may remain under the control of the assignor or licensor.
Our rights to develop and commercialize the product candidates are subject to the validity of the intellectual property rights. Enforcement of any assigned
or licensed patents or defense or any claims asserting the invalidity of these patents is often subject to the control or cooperation of the assignor or licensor.
Legal action could be initiated against the original owners of the intellectual property that we acquired and an adverse outcome in such legal action could
harm our business because it might prevent such companies or institutions from continuing to assign intellectual property that we may need to operate our
business.

In addition, our rights to practice the inventions claimed in any patents and patent applications are subject to our assignors and licensors abiding
by the terms of those agreements and not terminating them. These agreements may be terminated by the assignor or licensor if we are in material breach of
certain terms or conditions of the agreement or in certain other circumstances. Our rights under these agreements are subject to our continued compliance
with the terms of the agreements, including the payment of royalties and other payment due under the agreements. Termination of these agreements could
prevent us from marketing some or all of our products. Because of the complexity of our products and the patents, determining the scope of the assignment
or license and related royalty obligations can be difficult and can lead to disputes between us and the assignor or licensor. An unfavorable resolution of
such a dispute could lead to an increase in the royalties payable pursuant to the agreement. If the assignor or licensor believed we were not paying the
royalties due under the agreement or were otherwise not in compliance with the terms of the agreement, the assignor or licensor might attempt to revoke the
agreement. If such an attempt were successful, we might be barred from producing and selling some or all of our products.

It may be difficult and costly to protect our intellectual property rights, and we cannot ensure the protection of these rights.

Our  commercial  success  will  depend,  in  part,  on  obtaining  and  maintaining  patent  protection  for  our  technologies,  products  and  processes,
successfully  defending  these  patents  against  third-party  challenges  and  successfully  enforcing  these  patents  against  third-party  competitors.  The  patent
positions  of  pharmaceutical  companies  can  be  highly  uncertain  and  involve  complex  legal,  scientific  and  factual  questions  for  which  important  legal
principles  remain  unresolved.  Changes  in  either  the  patent  laws  or  in  interpretations  of  patent  laws  may  diminish  the  value  of  our  intellectual  property.
Accordingly, we cannot predict the breadth of claims that may be allowable or enforceable in our patents. Patent and patent applications relating to our
product candidates and related technologies may be challenged, invalidated or circumvented by third parties and might not protect us against competitors
with similar products or technologies.

The degree of future protection for our proprietary rights is uncertain, because legal means afford only limited protection and may not adequately
protect our rights, permit us to gain or keep our competitive advantage, or provide us with any competitive advantage at all. For example, others have filed,
and in the future are likely to file, patent applications covering products and technologies that are similar, identical or competitive to any of our product
candidates,  or  important  to  our  business.  We  cannot  be  certain  that  any  patent  application  owned  by  a  third  party  will  not  have  priority  over  patent
applications filed by us, or that we will not be involved in interference, opposition or invalidity proceedings before U.S. or foreign patent offices.

Additionally,  if  we  or  one  of  our  licensing  partners  initiated  legal  proceedings  against  a  third  party  to  enforce  a  patent  covering  any  product
candidate, the defendant could counterclaim that the patent covering any other product candidate is invalid and/or unenforceable. In patent litigation in the
United  States,  defendant  counterclaims  alleging  invalidity  and/or  unenforceability  are  commonplace.  Grounds  for  a  validity  challenge  include  alleged
failures to meet any of several statutory requirements, including lack of novelty, obviousness or non-enablement. Grounds for unenforceability assertions
include allegations that someone connected with prosecution of the patent withheld relevant information from the U.S. Patent and Trademark Office (“U.S.
PTO”), or made a misleading statement, during prosecution. Third parties may also 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  and  equivalent  proceedings  in  foreign
jurisdictions, e.g., opposition proceedings. Such proceedings could result in revocation or amendment of our patents or our licensors’ patents in such a way
that  they  no  longer  cover  product  candidates  or  competitive  products.  The  outcome  following  legal  assertions  of  invalidity  and  unenforceability  is
unpredictable. With respect to validity, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were
unaware  during  prosecution.  If  a  defendant  were  to  prevail  on  a  legal  assertion  of  invalidity  and/or  unenforceability,  we  would  lose  at  least  part,  and
perhaps all, of the patent protection on any product candidate. Such a loss of patent protection would have a material adverse impact on our business.

In  the  future,  we  may  rely  on  know-how  and  trade  secrets  to  protect  technology,  especially  in  cases  when  we  believe  patent  protection  is  not
appropriate or obtainable. However, know-how and trade secrets are difficult to protect. While we intend to require employees, academic collaborators,
consultants and other contractors to enter into confidentiality agreements, we may not be able to adequately protect our trade secrets or other proprietary or
licensed information. Typically, research collaborators and scientific advisors have rights to publish data and information in which we may have rights. If
we cannot maintain the confidentiality of our proprietary technology and other confidential information, our ability to receive patent protection and our
ability to protect valuable information owned by us may be imperiled. Enforcing a claim that a third-party entity illegally obtained and is using any of our
trade secrets is expensive and time consuming, and the outcome is unpredictable. In addition, courts are sometimes less willing to protect trade secrets than
patents. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how.

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  and  jurisdictions  throughout  the  world  would  be  prohibitively
expensive, and our intellectual property rights in some countries outside the United States could be less extensive than those offered 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 do not have, or where we do not pursue and obtain, 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  product  and  our  patents  or  other  intellectual  property  rights  may  not  be  effective  or
sufficient to prevent them from competing. Even if we pursue and obtain issued patents in particular jurisdictions, our patent claims or other intellectual
property rights may not be effective or sufficient to prevent third parties from so competing.

Further, the laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the United States. Many
companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems
of some countries, particularly developing countries, do not favor the enforcement of patents and other intellectual property protection, especially those
relating  to  biotechnology.  This  could  make  it  difficult  for  us  to  stop  the  infringement  of  our  patents,  if  obtained,  or  the  misappropriation  of  our  other
intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third
parties. In addition, many countries limit the enforceability of patents against third parties, including government agencies or government contractors. In
these  countries,  patents  may  provide  limited  or  no  benefit.  Patent  protection  must  ultimately  be  sought  on  a  country-by-country  basis,  which  is  an
expensive and time-consuming process with uncertain outcomes. Accordingly, we may choose not to seek patent protection in certain countries, and we
will not have the benefit of patent protection in such countries.

Moreover, proceedings to enforce our patent rights, or those of our licensors or partners, in foreign jurisdictions could result in substantial costs
and divert our efforts and attention from other aspects of our business, could put our in-licensed patents, or any patents that we may own in the future, at
risk  of  being  invalidated  or  interpreted  narrowly,  could  put  our  owned  or  in-licensed  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.

If we fail to obtain or maintain patent protection or trade secret protection for our product candidates or our technologies, third parties could use
our  proprietary  information,  which  could  impair  our  ability  to  compete  in  the  market  and  adversely  affect  our  ability  to  generate  revenues  and  attain
profitability.

We may also rely on the trademarks we may develop to distinguish our products from the products of our competitors. We cannot guarantee that
any trademark applications filed by us or our business partners will be approved. Third parties may also oppose such trademark applications, or otherwise
challenge our use of the trademarks. In the event that the trademarks we use are successfully challenged, we could be forced to rebrand our products, which
could result in loss of brand recognition, and could require us to devote resources to advertising and marketing new brands. Further, we cannot provide
assurance that competitors will not infringe the trademarks we use, or that we will have adequate resources to enforce these trademarks.

Changes in either U.S. or foreign patent law or interpretation of such laws could diminish the value of patents in general, thereby impairing our ability
to protect our products.

As is the case with other biotechnology companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and
enforcing patents in the biotechnology industry involve both technological and legal complexity, and it therefore is costly, time-consuming and inherently
uncertain.  In  addition,  on  September  16,  2011,  the  Leahy-Smith  America  Invents  Act  (“AIA”),  was  signed  into  law.  The  AIA  includes  a  number  of
significant changes to U.S. patent law, including provisions that affect the way patent applications will be prosecuted and may also affect patent litigation.

An important change introduced by the AIA is that, as of March 16, 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 are filed by different parties claiming the same invention. A third party that
files a patent application in the U.S. PTO after that date but before us could therefore be awarded a patent covering an invention of ours even if we had
made the invention before it was made by the third party. This will require us to be cognizant going forward of the time from invention to filing of a patent
application.

Among some of the other changes introduced by the AIA are changes that limit where a patentee may file a patent infringement suit and providing
opportunities for third parties to challenge any issued patent in the U.S. PTO. This applies to all of our U.S. patents, even those issued before March 16,
2013. Because of a lower evidentiary standard necessary to invalidate a patent claim in the U.S. PTO proceedings compared to the evidentiary standard in
U.S.  federal  court,  a  third  party  could  potentially  provide  evidence  in  a  U.S.  PTO  proceeding  sufficient  for  the  U.S.  PTO  to  hold  a  claim  invalid  even
though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to
use the U.S. PTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a
district court action.

Depending  on  decisions  by  the  U.S.  Congress,  the  federal  courts,  the  U.S.  PTO,  or  similar  authorities  in  foreign  jurisdictions,  the  laws  and
regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing in-licensed
patents and patents that we might obtain in the future.

Our product candidates may infringe the intellectual property rights of others, which could increase our costs and delay or prevent our development
and commercialization efforts.

Our  success  depends  in  part  on  avoiding  infringement  of  the  proprietary  technologies  of  others.  The  pharmaceutical  industry  has  been
characterized by frequent litigation regarding patent and other intellectual property rights. Identification of third-party patent rights that may be relevant to
our proprietary technology is difficult because patent searching is imperfect due to differences in terminology among patents, incomplete databases and the
difficulty in assessing the meaning of patent claims. Additionally, because patent applications are maintained in secrecy until the application is published,
we may be unaware of third-party patents that may be infringed by commercialization of any of our product candidates or any future product candidate.
There may be certain issued patents and patent applications claiming subject matter that we may be required to license in order to research, develop or
commercialize any of our product candidates, and we do not know if such patents and patent applications would be available to license on commercially
reasonable terms, or at all. Any claims of patent infringement asserted by third parties would be time-consuming and may:

● result in costly litigation;

● divert the time and attention of our technical personnel and management;

● prevent us from commercializing a product until the asserted patent expires or is held finally invalid or not infringed in a court of law;

● require us to cease or modify our use of the technology and/or develop non-infringing technology; or

● require us to enter into royalty or licensing agreements.

Third parties may hold proprietary rights that could prevent any of our product candidates from being marketed. Any patent-related legal action
against  us  claiming  damages  and  seeking  to  enjoin  commercial  activities  relating  to  any  of  our  product  candidates  or  our  processes  could  subject  us  to
potential liability for damages and require us to obtain a license to continue to manufacture or market any of our product candidates or any future product
candidates.  We  cannot  predict  whether  we  would  prevail  in  any  such  actions  or  that  any  license  required  under  any  of  these  patents  would  be  made
available on commercially acceptable terms, if at all. In addition, we cannot be sure that we could redesign our product candidates or any future product
candidates or processes to avoid infringement, if necessary. Accordingly, an adverse determination in a judicial or administrative proceeding, or the failure
to obtain necessary licenses, could prevent us from developing and commercializing any of our product candidates or a future product candidate, which
could harm our business, financial condition and operating results.

We expect that there are other companies, including major pharmaceutical companies, working in the areas competitive to our proposed product
candidates which either has resulted, or may result, in the filing of patent applications that may be deemed related to our activities. If we were to challenge
the validity of these or any issued U.S. patent in court, we would need to overcome a statutory presumption of validity that attaches to every issued U.S.
patent. This means that, in order to prevail, we would have to present clear and convincing evidence as to the invalidity of the patent’s claims. If we were to
challenge the validity of these or any issued U.S. patent in an administrative trial before the Patent Trial and Appeal Board in the U.S. PTO, we would have
to prove that the claims are unpatentable by a preponderance of the evidence. There is no assurance that a jury and/or court would find in our favor on
questions of infringement, validity or enforceability.

Others may claim an ownership interest in our intellectual property, which could expose us to litigation and have an adverse effect on our prospects.

A third party may claim an ownership interest in one or more of our or our licensors’ patents or other proprietary or intellectual property rights. A
third  party  could  bring  legal  actions  against  us  and  seek  monetary  damages  and/or  enjoin  clinical  testing,  manufacturing  and  marketing  of  the  affected
product or products. We cannot guarantee that a third party will not assert a claim or an interest in any of such patents or intellectual property. If we become
involved  in  any  litigation,  it  could  consume  a  substantial  portion  of  our  resources,  and  cause  a  significant  diversion  of  effort  by  our  technical  and
management personnel. If any of these actions are successful, in addition to any potential liability for damages, we could be required to obtain a license to
continue to manufacture or market the affected product, in which case we may be required to pay substantial royalties or grant cross-licenses to our patents.
We  cannot,  however,  assure  you  that  any  such  license  will  be  available  on  acceptable  terms,  if  at  all.  Ultimately,  we  could  be  prevented  from
commercializing a product candidate, or be forced to cease some aspect of our business operations as a result of claims of patent infringement or violation
of other intellectual property rights. Further, the outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in
advance, including the demeanor and credibility of witnesses and the identity of any adverse party. This is especially true in intellectual property cases that
may turn on the testimony of experts as to technical facts upon which experts may reasonably disagree.

We  may  be  subject  to  claims  that  we  have  wrongfully  hired  an  employee  from  a  competitor  or  that  we  or  our  employees  have  wrongfully  used  or
disclosed alleged confidential information or trade secrets of their former employers.

As is commonplace in our industry, we will employ individuals who were previously employed at other pharmaceutical companies, including our
competitors or potential competitors. Although no claims against us are currently pending, we may be subject in the future to claims that our employees or
prospective employees are subject to a continuing obligation to their former employers (such as non-competition or non-solicitation obligations) or claims
that  our  employees  or  we  have  inadvertently  or  otherwise  used  or  disclosed  trade  secrets  or  other  proprietary  information  of  their  former  employers.
Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial
costs and be a distraction to management.

Risks Related to Owning Our Common Stock

An active, liquid and orderly trading market for our shares may not continue to be developed or sustained.

Our common stock is listed on the Nasdaq Global Market. However, trading volume has been limited and a more active public market for our
common stock may not develop or be sustained over time. The market price of our common stock could be subject to significant fluctuations. The price of
our  stock  may  change  in  response  to  variations  in  our  operating  results  and  also  may  change  in  response  to  other  factors,  including  factors  specific  to
companies in our industry many of which are beyond our control. Our shares may be less liquid than the shares of other public companies and there may be
imbalances between supply and demand for our shares. As a result, our share price may experience significant volatility and may not necessarily reflect the
value  of  our  expected  performance.  Moreover,  sales  of  our  common  stock  in  the  public  market,  or  the  perception  that  such  sales  could  occur,  could
negatively  impact  the  price  of  our  common  stock.  As  a  result,  you  may  not  be  able  to  sell  your  shares  of  our  common  stock  in  short  time  periods,  or
possibly at all, and the price per share of our common stock may fluctuate significantly.

Future capital raises may dilute our existing stockholders’ ownership, could depress the market price for our common stock and have other adverse
effects on our operations.

We  have  an  effective  Form  S-3  registration  statement  (“Shelf  Registration”)  on  file  with  the  SEC  which  allows  us  to  sell  any  combination  of
common stock, preferred stock, debt securities, warrants to purchase any of these securities, subscription rights to purchase any of these securities, and/or
units consisting of one or more of the foregoing in one or more offerings up to a total dollar amount of $100 million (including the $22.5 million raised in
our October 2020 offering of common stock). The issuance of additional shares of our common stock pursuant to the Shelf Registration, or issuances of
securities  convertible  into  or  exercisable  for  our  common  stock  or  other  equity-linked  securities,  including  preferred  stock,  warrants,  debt  securities  or
units, would dilute the ownership interest of our common shareholders and could depress the market price of our common stock and impair our ability to
raise capital through the sale of additional equity securities. If we raise additional funds by issuing debt securities, these debt securities would have rights
senior to those of our common stock and the terms of the debt securities issued could impose significant restrictions on our operations, including liens on
our assets. If we raise additional funds through collaborations and licensing arrangements, we may be required to relinquish some rights to our technologies
or candidate products, or to grant licenses on terms that are not favorable to us.

39

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

The trading price of our common stock has fluctuated significantly in the past and is likely to be volatile. The stock market in general, and early
stage  public  companies  in  particular,  has  experienced  extreme  price  and  volume  fluctuations  that  have  often  been  unrelated  or  disproportionate  to  the
operating performance of such companies. The stock market in general has been, and the market price of our shares in particular will likely be, subject to
fluctuation, whether due to, or irrespective of, our operating results and financial condition. The market price of our shares on the Nasdaq Global Market
may fluctuate as a result of a number of factors, some of which are beyond our control, including, but not limited to:

● actual or anticipated variations in our and our competitors’ results of operations and financial condition;

● market acceptance of our products;

● the mix of products that we sell and related services that we provide;

● changes in earnings estimates or recommendations by securities analysts, if our shares are covered by analysts;

● development of technological innovations or new competitive products by others;

● announcements of technological innovations or new products by us;

● publication of the results of preclinical or clinical trials for our other product candidates;

● failure by us to achieve a publicly announced milestone;

● delays between our expenditures to develop and market new or enhanced products and the generation of sales from those products;

● developments concerning intellectual property rights, including our involvement in litigation brought by or against us;

● regulatory developments and the decisions of regulatory authorities as to the approval or rejection of new or modified products;

● changes in the structure of healthcare payment systems;

● changes in the amounts that we spend to develop, acquire or license new products, technologies or businesses;

● changes in our expenditures to promote our products;

● our sale or proposed sale, or the sale by our significant stockholders, of our shares or other securities in the future;

● changes in key personnel;

● success or failure of our research and development projects or those of our competitors;

● the trading volume of our shares; and

● general economic and market conditions and other factors, including factors unrelated to our operating performance.

These factors and any corresponding price fluctuations may materially and adversely affect the market price of our shares and result in substantial
losses being incurred by our investors. In the past, following periods of market volatility, public company stockholders have often instituted securities class
action  litigation.  If  we  were  involved  in  securities  litigation,  it  could  impose  a  substantial  cost  upon  us  and  divert  the  resources  and  attention  of  our
management from our business.

We are an “emerging growth company” under the JOBS Act of 2012 and we cannot be certain if the reduced disclosure requirements applicable to
emerging growth companies will make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”), and we may take advantage
of  certain  exemptions  from  various  reporting  requirements  that  are  applicable  to  other  public  companies  that  are  not  “emerging  growth  companies”
including, but not limited to:

● not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley

Act”);

● reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements;

● exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden

parachute payments; and

● extended transition periods available for complying with new or revised accounting standards.

We have chosen to “opt out” of the extended transition periods available for complying with new or revised accounting standards, but we intend to
take advantage of all of the other benefits available under the JOBS Act, including the exemptions discussed above. We cannot predict if investors will find
our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may
be a less active trading market for our common stock and our stock price may be more volatile.

We will remain an “emerging growth company” for up to five years from the end of the fiscal year following the fifth anniversary of the date of
the first sale of our common stock pursuant to an effective registration statement filed under the Securities Act, which will be December 31, 2023. We will
lose that status sooner, however, if our revenues exceed $1.07 billion, if we issue more than $1 billion in non-convertible debt in a three-year period or if
the market value of our common stock that is held by non-affiliates exceeds $700 million as of any June 30.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or
prevent  fraud.  As  a  result,  stockholders  could  lose  confidence  in  our  financial  and  other  public  reporting,  which  would  harm  our  business  and  the
trading price of our common shares.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure
controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their
implementation could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404 of the
Sarbanes-Oxley Act, or the subsequent testing by our independent registered public accounting firm when required, may reveal deficiencies in our internal
controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retrospective changes to our consolidated
financial statements or identify other areas for further attention or improvement. Inferior internal controls could also cause investors to lose confidence in
our reported financial information, which could have a negative effect on the trading price of our common shares. There is also a risk that neither we nor
our independent registered public accounting firm (when applicable in the future) will be able to conclude within the prescribed timeframe that internal
controls over financial reporting is effective as required by Section 404. This could result in an adverse reaction in the financial markets due to a loss of
confidence in the reliability of our financial statements.

Our status as an “emerging growth company” under the JOBS Act may make it more difficult to raise capital as and when we need it.

Because of the exemptions from various reporting requirements provided to us as an “emerging growth company,” we may be less attractive to
investors and it may be difficult for us to raise additional capital as and when we need it. Investors may be unable to compare our business with other
companies in our industry if they believe that our reporting is not as transparent as other companies in our industry. If we are unable to raise additional
capital as and when we need it, our financial condition and results of operations may be materially and adversely affected.

We have not paid dividends in the past and have no immediate plans to pay dividends, so any returns will be limited to the value of our stock.

We plan to reinvest all of our earnings, to the extent we have earnings, to cover operating costs and otherwise become and remain competitive. We
do not plan to pay any cash dividends with respect to our securities in the foreseeable future. We cannot assure you that we would, at any time, generate
sufficient  surplus  cash  that  would  be  available  for  distribution  to  the  holders  of  our  common  stock  as  a  dividend.  Therefore,  you  should  not  expect  to
receive cash dividends on our common stock, and any return to stockholders will therefore be limited to the appreciation of their stock.

If equity research analysts do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our shares, the
price of our shares could decline.

The trading market for our shares will rely in part on the research and reports that equity research analysts publish about us and our business, if at
all. We do not have control over these analysts, and we do not have commitments from them to write research reports about us. The price of our shares
could decline if no research reports are published about us or our business, or if one or more equity research analysts downgrades our shares or if those
analysts issue other unfavorable commentary or cease publishing reports about us or our business.

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

Our federal net operating losses (“NOLs”) generated in taxable years ending prior to 2018 could expire unused. Under the Tax Act, federal NOLs
incurred in taxable years ending after December 31, 2017, may be carried forward indefinitely, but the deductibility of federal NOLs generated in tax years
beginning before December 31, 2017, is limited. It is uncertain if and to what extent various states will conform to the Tax Act. In addition, under Sections
382  and  383  of  the  Internal  Revenue  Code  of  1986,  as  amended,  and  corresponding  provisions  of  state  law,  if  a  corporation  undergoes  an  “ownership
change,” which is generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to
use its pre-change NOL carryforwards, or NOLs, and other pre-change tax attributes (such as research tax credits) to offset its post-change income may be
limited. We are performing a study to determine if we have triggered any “ownership change” limitations. We may also experience ownership changes in
the future as a result of subsequent shifts in our stock ownership some of which may be outside of our control. As a result, if we earn net taxable income,
our ability to use our pre-ownership change NOL carryforwards to offset U.S. federal taxable income may be subject to limitations, which could potentially
result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise
limited, which could accelerate or permanently increase state taxes owed.

Assuming a market for our common stock continues to develop, sales of a substantial number of shares of our common stock in the public market by
our existing stockholders could cause our stock price to fall.

Sales of a substantial number of shares of our common stock by our existing stockholders in the public market or the perception that these sales
might  occur,  could  depress  the  market  price  of  our  common  stock  and  could  impair  our  ability  to  raise  capital  through  the  sale  of  additional  equity
securities. We are unable to predict the effect that such sales may have on the prevailing market price of our common stock.

As of March 7, 2022, we had 24,626,004 shares of common stock outstanding, all of which, other than shares held by our directors and certain
officers, are eligible for sale in the public market, subject in some cases to compliance with the requirements of Rule 144, including volume limitations and
manner of sale requirements.

Certain holders of our securities are entitled to rights with respect to the registration of their shares under the Securities Act of 1933, as amended
(the “Securities Act”). Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the
Securities Act. Any sales of securities by these stockholders could have a material adverse effect on the trading price of our common stock.

We may be at an increased risk of securities class action litigation.

Historically, securities class action litigation has often been brought against a company following a decline in the market price of its securities.
This risk is especially relevant for us because biotechnology and pharmaceutical companies have experienced significant stock price volatility in recent
years. If we were to be sued, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

Our charter documents and Delaware law may inhibit a takeover that stockholders consider favorable.

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws and applicable provisions of Delaware law
may  delay  or  discourage  transactions  involving  an  actual  or  potential  change  in  control  or  change  in  our  management,  including  transactions  in  which
stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests.
The provisions in our amended and restated certificate of incorporation and amended and restated bylaws:

● authorize our board of directors to issue, without further action by the stockholders, shares of undesignated preferred stock with terms, rights

and preferences determined by our board of directors that may be senior to our common stock;

● establish an advance notice procedure for stockholder proposals to be brought before an annual meeting, including proposed nominations of

persons for election to our board of directors;

● establish that our board of directors is divided into three classes, with each class serving three-year staggered terms;

● require the approval of our board of directors or the holders of at least seventy-five percent (75%) of our outstanding shares of capital stock to

amend our bylaws and certain provisions of our certificate of incorporation;

● limit who may call stockholder meetings;

● do not provide for cumulative voting rights; and

● provide that all vacancies may be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum.

In addition, Section 203 of the Delaware General Corporation Law may limit our ability to engage in any business combination with a person who
beneficially  owns  15%  or  more  of  our  outstanding  voting  stock  unless  certain  conditions  are  satisfied.  This  restriction  lasts  for  a  period  of  three  years
following  the  share  acquisition.  These  provisions  may  have  the  effect  of  entrenching  our  management  team  and  may  deprive  our  stockholders  of  the
opportunity to sell their shares to potential acquirers at a premium over prevailing prices. This potential inability to obtain a control premium could reduce
the price of our common stock.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for
certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes
with us or our directors, officers or stockholders.

Provisions in our amended and restated certificate of incorporation provide that the Court of Chancery of the State of Delaware will, to the fullest

extent permitted by law, be the sole and exclusive forum for:

● any derivative action or proceeding brought on our behalf;

● any action asserting a claim of breach of a fiduciary duty owed to us or our stockholders by any of our directors, officers or other employees;

● any action asserting a claim against us or any of our directors, officers or other employees arising pursuant to any provision of Delaware law

or our charter documents; or

● any action  asserting  a  claim  against  us  or  any  of  our  directors,  officers  or  other  employees  governed  by  the  internal  affairs  doctrine,  but
excluding actions to enforce a duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive
jurisdiction.

In  addition,  unless  we  consent  in  writing  to  the  selection  of  an  alternative  forum,  the  Federal  district  courts  of  the  United  States  shall  be  the
exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. However, a court may determine that this
provision is unenforceable.

Ownership portions held by our executives and directors, as well as by our former parent company, Harrow Health, Inc., may limit our stockholders’
ability to influence corporate matters.

Our directors and executive officers beneficially own approximately 5.2% of our common stock. Additionally, Harrow Health, Inc. (“Harrow”),
our former parent company, holds approximately 8.0% of our outstanding common stock as of March 7, 2022. Accordingly, these parties, together, can
significantly influence, though not independently determine, the outcome of matters required to be submitted to our stockholders for approval, including
decisions relating to the election of our board of directors and the outcome of any proposed merger or consolidation of our company. These interests may
not be consistent with those of our other stockholders. In addition, the significant interest held by these parties, and particularly by Harrow, may discourage
third parties from seeking to acquire control of us, which may adversely affect the market price of our shares.

As  stockholders  in  our  company,  you  will  be  deemed  to  have  notice  of  and  have  consented  to  the  provisions  of  our  amended  and  restated
certificate of incorporation related to choice of forum, but will not be deemed to have waived our compliance with the federal securities laws and the rules
and regulations thereunder. The choice of forum provisions in our amended and restated certificate of incorporation may limit our stockholders’ ability to
obtain a favorable judicial forum for disputes with us or any of our directors, officers or other employees, which may discourage lawsuits with respect to
such claims. Alternatively, if a court were to find the choice of forum provision contained in our restated charter to be inapplicable or unenforceable in an
action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, results of operations and
financial condition.

involve risks and uncertainties. For a complete discussion of forward-looking statements, see the section above entitled “Forward Looking Statements.”
Our actual results could differ materially from those expressed or implied in any forward-looking statements as a result of various factors, including those
set forth under the caption “Item 1A. Risk Factors.”

Overview

We are a unique pharmaceutical company focused on developing, acquiring, and commercializing innovative pharmaceutical products that fulfill
an  unmet  patient  need.  Since  the  formation  of  our  company  in  2017,  we  have  used  our  expertise  in  business  development,  regulatory,  and  product
development to assemble a diversified portfolio of eleven products. Six of our products have been approved by the FDA and commercially launched. We
plan to continue growing our business through the acquisition of additional late-stage, high-value product candidates.

Results of Operations

To date, we have realized revenues from the sale of our neurology products portfolio to Azurity in 2021, a licensing arrangement on our EM-100
product  that  was  sold  to  Bausch  Health  and  also  the  launch  of  our  Biorphen®,  Alkindi  Sprinkle®,  and  Carglumic  Acid  products  in  December  2019,
December 2020, and December 2021, respectively. We anticipate successfully growing our sales for these products and commercializing additional product
candidates in 2022 and beyond.

Year Ended December 31, 2021 Compared to Year Ended December 31, 2020

Net revenues of $21.8 million in 2021 included $19.0 million of milestones, including $17.0 million from Azurity on three neurology products
sold  to  them  at  the  beginning  of  the  year.  Revenues  were  nominal  in  2020  for  Biorphen  and  reflected  the  launch  of  Alkindi  Sprinkle®  late  in  mid-
December.

Our 2021 gross profit of $19.2 million was up significantly as the prior year negative gross profit level was adversely impacted by Biorphen price
discounts and a reserve charge to cost of sales for certain slow-moving Biorphen inventory that we do not believe we will be able to sell before its expiry
date.

For the years ended December 31, 2021 and 2020, we incurred $6.2 million and $14.1 million of research and development (“R&D”) expenses,
respectively, and $14.5 million and $12.8 million of general and administrative (“G&A”) expenses, respectively. The $7.9 million decrease in R&D was
driven  by  significant  milestone  payments  on  a  number  of  our  products  in  development  that  did  not  recur  in  2021.  The  $1.7  million  increase  in  G&A
expenses was primarily due to personnel additions and increased professional/consulting spending to support our growing business. We incurred a net loss
of $2.0 million and $28.0 million for the years ended December 31, 2021 and 2020, respectively.

General and Administrative Expenses

G&A  expenses  consist  primarily  of  employee  compensation  expenses,  selling  and  adverting/promotional  expenses,  legal  and  professional  fees,
business insurance and FDA fees. We anticipate that our G&A expenses will increase to support our business growth – particularly with respect to sales
and marketing for additional personnel and promotional expenses.

Research and Development Expenses

We currently have seven employees that support our overall product development function. The majority of our spend in R&D is to third parties

we contract with to develop and test our products in addition to development partner milestone payments. We closed our R&D facility in May 2021.

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019

Net  revenues  for  2020  reflected  limited  benefit  from  Alkindi  Sprinkle  which  launched  in  mid-December.  In  addition,  revenue  was  negatively
impacted by a price discount for Biorphen in 2020 related to the shelf stock at our wholesale customers. Our 2020 gross profit was also adversely impacted
by  a  reserve  charge  to  cost  of  sales  for  certain  slow-moving  Biorphen  inventory  that  we  do  not  believe  we  will  be  able  to  sell  before  its  expiry  date.
Revenue and gross profit in 2019 reflected the initial launch for Biorphen and a $0.5 million milestone payment for our sale of EM-100 to Bausch Health.

For the years ended December 31, 2020 and 2019, we incurred $14.1 million and $11.6 million of research and development (“R&D”) expenses,
respectively,  and  $12.8  million  and  $7.6  million  of  general  and  administrative  (“G&A”)  expenses,  respectively.  The  increase  in  R&D  expense  was
primarily due to $4.8 million of licensing and development fees for Alkindi Sprinkle in 2020 offset by reduced spending for Topiramate and Lamotrigine.
The $5.2 million increase in G&A expenses was primarily due to personnel additions and increased sales/marketing spending to support product launches.
In addition, we incurred significant legal expenses associated with our patent challenge against Exela Pharma Sciences for the Cysteine product that we
have in development. We incurred a net loss of $28.0 million and $18.3 million for the years ended December 31, 2020 and 2019, respectively.

General and Administrative Expenses

G&A expenses consisted primarily of employee compensation expenses, selling and adverting/promotional expenses, legal and professional fees,
business insurance and travel expenses. Our G&A expenses increased to support our business growth – particularly with respect to sales and marketing for
additional personnel and promotional expenses.

Research and Development Expenses

As of December 31, 2020, we had six employees that supported our overall product development and we had facility and operating costs for a

laboratory to support product development which we subsequently closed in May 2021.

Liquidity and Capital Resources

As of December 31, 2021, we had total assets of $27.5 million, cash and cash equivalents of $14.4 million and working capital of $19.0 million.
We  had  previously  capitalized  our  operations  from  the  June  2017  private  placement  of  approximately  $20.1  million  of  Series  A  preferred  stock  which
converted into shares of our common stock concurrent with our IPO in November 2018 and also the IPO which provided us with net proceeds of $22.0
million. In addition, we entered into a Credit Agreement with SWK Holdings in November 2019 whereby we drew a $5.0 million loan amount at closing
and an additional $2.0 million in August 2020. In March and April 2020, we received net proceeds of approximately $7.8 million from the sale of shares of
our  common  stock,  and  in  October  2020,  we  received  net  proceeds  of  approximately  $21.0  million  from  a  public  offering  of  our  common  stock  at  an
offering price of $7.00 per share. We believe that our existing funding, revenues from our approved products and milestone payments expected to be paid in
2022  will  be  sufficient  for  at  least  the  next  twelve  months  of  our  operations.  However,  our  projected  estimates  for  our  product  development  spending,
administrative expenses and our working capital requirements could be inaccurate, or we may experience growth more quickly or on a larger scale than we
expect, any of which could result in the depletion of capital resources more rapidly than anticipated and could require us to seek additional financing earlier
than we expect to support our operations.

Cash Flows

The following table sets forth a summary of our cash flows for the years ended December 31, 2021, 2020 and 2019 (amounts are in thousands):

The decrease in cash used in operating activities is primarily a result of lower operating losses, driven by higher revenue. Investing activities in
2021 consist primarily of licensing fees for Carglumic Acid, partially offset by the proceeds from the sale of equipment from our laboratory facility which
we closed in May 2021. The financing activity primarily consists of the October 2020 follow-on common stock offering and the November 2019 Credit
Agreement borrowing from SWK Holdings.

Critical Accounting Policies

Our financial statements are prepared in accordance with GAAP. The preparation of our financial statements and related disclosures requires us to
make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses in our financial statements. We base our estimates
on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which
form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our
estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 3 to our financial statements included herein, we believe that the

following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements.

Revenue Recognition

We account for contracts with our customers in accordance with Accounting Standards Codification (“ASC”) 606 — Revenue from Contracts with
Customers. 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 which 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.

49

 
 
 
 
 
 
 
 
   
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each
contract  and  determines  those  that  are  performance  obligations  and  assesses  whether  each  promised  good  or  service  is  distinct.  We  then  recognize  as
revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.
Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. We assess
whether these options provide a material right to the customer and, if so, they are considered performance obligations. The exercise of a material right is
accounted for as a contract modification for accounting purposes.

We  recognize  as  revenue  the  amount  of  the  transaction  price  that  is  allocated  to  the  respective  performance  obligation  when  (or  as)  each
performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method. Any amounts
received  prior  to  revenue  recognition  will  be  recorded  as  deferred  revenue.  Amounts  expected  to  be  recognized  as  revenue  within  the  twelve  months
following the balance sheet date will be classified as current portion of deferred revenue in our balance sheets. Amounts not expected to be recognized as
revenue within the twelve months following the balance sheet date are classified as long-term deferred revenue, net of current portion.

Milestone Payments – If a commercial contract arrangement includes development and regulatory milestone payments, we will evaluate 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. Milestone payments that are not within our control or the licensee’s control, such as regulatory approvals, are generally not considered probable of
being achieved until those approvals are received.

Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a
customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, we will recognize revenue at the
later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied or
partially satisfied.

Significant Financing Component – In determining the transaction price, we will adjust consideration for the effects of the time value of money if

the expected period between payment by the licensees and the transfer of the promised goods or services to the licensees will be more than one year.

We sell Biorphen in the U.S. to wholesale pharmaceutical distributors, who then sell the product to hospitals and other end-user customers. Sales
to wholesalers are made pursuant to purchase orders subject to the terms of a master agreement, and delivery of individual shipments of Biorphen represent
performance obligations under each purchase order. We use a third-party logistics (“3PL”) vendor to process and fulfill orders and have concluded it is the
principal  in  the  sales  to  wholesalers  because  it  controls  access  to  the  3PL  vendor  services  rendered  and  directs  the  3PL  vendor  activities.  We  have  no
significant  obligations  to  wholesalers  to  generate  pull-through  sales.  In  addition,  we  sell  our  Alkindi  Sprinkle  and  Carglumic  Acid  products  to  one
pharmacy distributor customer which provides order fulfillment and inventory storage/distribution services.

Selling prices initially billed to wholesalers are subject to discounts for prompt payment and subsequent chargebacks when the wholesalers sell
Biorphen at negotiated discounted prices to members of certain group purchasing organizations (“GPOs”) and government programs. In addition, we pay
fees to wholesalers for their distribution services, inventory reporting and chargeback processing. We pay GPOs fees for administrative services and for
access to GPO members and concluded the benefits received in exchange for these fees are not distinct from our sales of Biorphen, and accordingly we
apply these amounts to reduce revenues. Wholesalers also have rights to return unsold product nearing or past the expiration date. Because of the shelf life
of Biorphen and our lengthy return period, there may be a significant period of time between when the product is shipped and when we issue credits on
returned product. For our Alkindi Sprinkle and Carglumic Acid products, we bill at the initial product list prices which are subject to offsets for patient co-
pay assistance and potential state Medicaid reimbursements which are estimated and recorded as a reduction of net revenues at the date of sale/shipment.

We estimate the transaction price when we receive each purchase order, taking into account the expected reductions of the selling price initially
billed to the wholesaler arising from all of the above factors. We have developed estimates for future returns and chargebacks of Biorphen and the impact
of the other discounts and fees we pay. Our sales of Alkindi Sprinkle and Carglumic Acid to our distributor are not subject to returns. When estimating
these adjustments to the transaction price, we reduce it sufficiently to be able to assert that it is probable that there will be no significant reversal of revenue
when the ultimate adjustment amounts are known.

We recognize revenue from Biorphen product sales and related cost of sales upon product delivery to the wholesaler location. At that time, the
wholesalers take control of the product as they take title, bear the risk of loss of ownership, and have an enforceable obligation to pay us. They also have
the ability to direct sales of product to their customers on terms and at prices they negotiate. Although wholesalers have product return rights, we do not
believe  they  have  a  significant  incentive  to  return  the  product  to  us.  We  store  our  Alkindi  Sprinkle  and  Carglumic  Acid  inventory  at  our  pharmacy
distributor customer location and sales are recorded when stock is pulled and shipped to fulfill specific patient orders.

50

 
 
 
 
 
 
 
 
 
 
 
Upon  recognition  of  revenue  from  product  sales,  the  estimated  amounts  of  credit  for  product  returns,  chargebacks,  distribution  fees,  prompt
payment  discounts,  state  Medicaid  and  GPO  fees  are  included  in  sales  reserves,  accrued  liabilities  and  net  of  accounts  receivable.  We  monitor  actual
product returns, chargebacks, discounts and fees subsequent to the sale. If these amounts end up differing from our estimates, we will make adjustments to
these allowances, which are applied to increase or reduce product sales revenue and earnings in the period of adjustment.

In  addition,  we  anticipate  we  will  receive  revenues  from  product  licensing  agreements  where  we  have  contracted  for  milestone  payments  and

royalties from products we have developed or for which we have acquired the rights to a product developed by a third party.

Stock-Based Compensation

We account for stock-based compensation under the provisions of ASC 718 Compensation – Stock Compensation. The guidance under ASC 718
requires  companies  to  estimate  the  fair  value  of  the  stock-based  compensation  awards  on  the  date  of  grant  and  record  expense  over  the  related  service
periods,  which  are  generally  the  vesting  period  of  the  equity  awards.  Compensation  expense  is  recognized  over  the  period  during  which  services  are
rendered by consultants and non-employees until completed. At the end of each financial reporting period prior to completion of the service, the fair value
of these awards is remeasured using the then-current fair value of our common stock and updated assumption inputs in the Black-Scholes option-pricing
model (“BSM”).

We estimate the fair value of stock-based option awards to our using the BSM. The BSM requires the input of subjective assumptions, including
the expected stock price volatility, the calculation of expected term, forfeitures and the fair value of the underlying common stock on the date of grant,
among  other  inputs.  The  risk-free  interest  rate  was  determined  from  the  implied  yields  for  zero-coupon  U.S.  government  issues  with  a  remaining  term
approximating the expected life of the options or warrants. Dividends on common stock are assumed to be zero for the BSM valuation of the stock options.
The expected term of stock options granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable
companies’ historical volatility along with a limited weighting included for our own volatility subsequent to our IPO, which we believe represents the most
accurate basis for estimating expected future volatility under the current conditions. We account for forfeitures as they occur.

Prior  to  our  initial  public  offering  in  November  2018,  the  fair  value  of  the  shares  of  common  stock  underlying  our  stock-based  awards  was
determined by our board of directors, with input from management. Because there had been no public market for our common stock prior to the IPO, our
board of directors had determined the fair value of the common stock on the grant-date of the stock-based award by considering a number of objective and
subjective  factors,  including  enterprise  valuations  of  our  common  stock  performed  by  an  unrelated  third-party  specialist,  valuations  of  comparable
companies, sales of our convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of our capital stock,
and  general  and  industry-specific  economic  outlook.  Following  our  IPO,  we  use  the  closing  stock  price  on  the  date  of  grant  for  the  fair  value  of  the
common stock.

Research and Development Expenses

R&D expenses include both internal R&D activities and external contracted services. Internal R&D activity expenses include salaries, benefits and
stock-based  compensation  and  other  costs  to  support  our  R&D  operations.  External  contracted  services  include  product  development  efforts  including
certain product licensor milestone payments, clinical trial activities, manufacturing and control-related activities and regulatory costs. R&D expenses are
charged to operations as incurred. We review and accrue R&D expenses based on services performed and rely upon estimates of those costs applicable to
the  stage  of  completion  of  each  project.  Significant  judgments  and  estimates  are  made  in  determining  the  accrued  balances  at  the  end  of  any  reporting
period. Actual results could differ from our estimates.

Upfront payments and milestone payments made for the licensing of technology for products that are not yet approved by the FDA are expensed
as  R&D  in  the  period  in  which  they  are  incurred.  Nonrefundable  advance  payments  for  goods  or  services  to  be  received  in  the  future  for  use  in  R&D
activities are recorded as prepaid expenses and are expensed as the related goods are delivered or the services are performed.

Off Balance Sheet Transactions

We do not have any off-balance sheet transactions.

JOBS Act Transition Period

In April 2012, the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), was enacted. Section 107 of the JOBS Act provides that an
“emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with
new  or  revised  accounting  standards.  Thus,  an  emerging  growth  company  can  delay  the  adoption  of  certain  accounting  standards  until  those  standards
would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will
adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.

Subject  to  certain  conditions,  as  an  emerging  growth  company,  we  may  rely  on  certain  of  these  exemptions,  including  without  limitation,  (i)
providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act
and (ii) complying with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation
or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and
analysis. We will remain an emerging growth company until the earlier to occur of (1) the last day of the fiscal year (a) December 31, 2023, which is the
end of the fiscal year following the fifth anniversary of the completion of our IPO, (b) in which we have total annual gross revenues of at least $1.07 billion
or (c) in which we are deemed to be a “large accelerated filer” under the rules of the SEC, which means the market value of our common stock that is held
by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt
during the prior three-year period.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The  primary  objective  of  our  investment  activities  is  to  preserve  capital.  We  do  not  utilize  hedging  contracts  or  similar  instruments.  We  are
exposed to certain market risks relating primarily to interest rate risk on our cash and cash equivalents and risks relating to the financial viability of the
institutions which hold our capital and through which we have invested our funds. We manage such risks by investing in short-term, liquid, highly rated
instruments. As of December 31, 2021, our cash equivalents only included cash deposits at our bank. From time to time, we do have cash investments in
short-term money market or U.S. treasury bills. We do not believe we have any material exposure to interest rate risk due to the extremely low interest rate
environment and the short duration of the invested funds we hold. Declines in interest rates would reduce our investment income but would not have a
material effect on our financial condition or results of operations. We do not currently have exposure to foreign currency risk.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Eton Pharmaceuticals, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  Eton  Pharmaceuticals,  Inc.  (the  “Company”)  as  of  December  31,  2021  and  2020,  the  related
statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2021, and the related notes
(collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position
of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended
December 31, 2021, in conformity with 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  Company’s  internal  control  over
financial reporting. Accordingly, we express no such opinion.

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in
the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as
evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  financial  statements  that  was  communicated  or
required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2)
involved  our  especially  challenging,  subjective,  or  complex  judgments.  The  communication  of  the  critical  audit  matter  does  not  alter  in  any  way  our
opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the
critical audit matter or on the accounts or disclosures to which it relates.

Product Sales Deductions

Critical Audit Matter Description

As described in Note 3 to the financial statements under the caption “Revenue Recognition for Contracts with Customers,” revenues from product sales are
recognized net of reductions for estimated returns, chargebacks, distribution fees, prompt payment discounts, state Medicaid and GPO fees (collectively
“sales deductions”), which are established at the time of sale.

Auditing the estimation of sales deductions was challenging because of the limited sales history of the Company’s products and the subjectivity of certain
assumptions  required  to  estimate  those  amounts.  In  particular,  management  estimates  potential  chargebacks,  which  relate  to  price  reductions  below  the
estimated sales price that the wholesalers provide to certain customers, based on historical industry data for competitive products and adjusted for actual
historical  experience.  In  addition,  management  estimates  its  provision  for  product  returns  based  on  prior  experience  with  similar  product  launches  and
considers other factors such as levels of inventory in the distribution channel, forecasted buying patterns, and product dating and expiration period. The
product  sales  deductions  are  estimated  based  on  current  contractual  and  statutory  requirements,  market  events  and  trends,  and  internal  and  external
historical data.

How the Critical Audit Matter Was Addressed in the Audit

To test management’s estimated product sales deductions, we obtained management’s calculations for the respective estimates and performed the following
procedures, among others. We tested management’s estimation process for determining of product sales discounts accruals by developing an independent
expectation of the estimated accrual rate, including a comparison of rates used in management’s forecast to rates in the underlying contracts and performing
a retrospective review of assumptions to actual activity. In addition, we assessed subsequent events to determine whether there was any new information
that would require adjustment to the initial accruals, evaluated trends in actual sales and discount accrual balances, and compared cash receipts to product
sales. We also examined terms and conditions for a sample of contracts with the Company’s customers, tested a sample of credits issued and payments
made throughout the year and agreed rates to underlying contract terms.

Note 1 — Company Overview

Eton Pharmaceuticals, Inc. (“Eton” or the “Company”) was incorporated as a Delaware “C” corporation on April 27, 2017 and was initially set up
as a wholly-owned subsidiary of Harrow Health, Inc. (“Harrow”, fka Imprimis Pharmaceuticals, Inc.). In June 2017, the Company raised $20,055 in start-
up capital through a private sale of preferred stock and a separate management team was then established for Eton with its corporate offices located in Deer
Park,  Illinois.  In  November  2018,  the  Company  completed  an  initial  public  offering  (the  “IPO”)  and  received  net  proceeds  of  $21,960,  after  deducting
underwriting discounts and commissions and offering-related expenses. In November 2019, the Company entered into a credit agreement and received net
proceeds of $4,750 and in August 2020 the Company received net proceeds of $1,965 under the credit agreement (see Note 5). In March and April 2020,
Eton received net proceeds of $7,756 from the sale of shares of its common stock and in October 2020, the Company received net proceeds of $21,026
from a public offering for its shares at an offering price of $7.00 per share (see Note 6).

Eton  is  a  specialty  pharmaceutical  company  focused  on  developing,  acquiring,  and  commercializing  innovative  products.  Eton  is  primarily
focused on hospital injectable and rare disease products. The Company seeks to improve the formula, delivery system, or safety of existing molecules in
order  to  address  unmet  patient  needs.  Eton  pursues  what  it  perceives  to  be  low-risk  product  candidates  where  existing  published  literature,  historical
clinical trials, or physician usage has established safety and/or efficacy of the molecule, thereby reducing the incremental clinical burden required for the
Company to bring the product to patients.

The Company’s Biorphen® product was approved by the FDA in October 2019 and sales commenced for this product at the end of 2019. Eton’s
EM-100 product was sold to Bausch Health and the product was approved by the FDA in September 2020. Bausch Health launched this product under the
name of Alaway® Preservative Free in January 2021 and Eton receives royalties from the sale of the product. The Company acquired the licensing rights to
Alkindi Sprinkle and this product was approved by the FDA in October 2020 and launched in December 2020. The Company entered into a co-promotion
agreement with Tolmar Pharmaceuticals in November 2021 whereby Tolmar will promote Alkindi Sprinkle through its 60+ person salesforce in exchange
for a royalty on net sales. In addition, the Company launched Carglumic Acid tablets in December 2021 as the first and only FDA-approved generic version
of Carbaglu®.

Note 2 — Liquidity Considerations

As of December 31, 2021, the Company had an accumulated deficit of $94,113 and for the year ended December 31, 2021 the Company used net

cash in operating activities of $4,721.

To date, the Company has generated revenues from six products and expects further growth in 2022 and beyond in accordance with additional
market penetration from these products plus revenues from licensing and additional products where it anticipates FDA approval. The Company currently
believes its existing cash and cash equivalents of $14,406 as of December 31, 2021 augmented by the $5,000 milestone payment received in January 2022
for  the  commercial  launch  of  EPRONTIA™  (Topiramate  oral  solution)  by  Azurity  Pharmaceuticals  (“Azurity”),  will  be  sufficient  to  fund  its  operating
expenses and capital expenditure requirements for at least the next twelve months from the date of issuance of these financial statements. This estimate is
based on the Company’s current assumptions, including assumptions relating to estimated sales and its ability to manage its spending. The Company could
use  its  available  capital  resources  sooner  than  currently  expected.  Accordingly,  the  Company  could  seek  to  obtain  additional  capital  through  equity
financings,  the  issuance  of  debt  or  other  arrangements.  However,  there  can  be  no  assurance  that  the  Company  will  be  able  to  raise  additional  capital  if
needed or under acceptable terms, if at all. The sale of additional equity may dilute existing stockholders and newly issued shares may contain senior rights
and preferences compared to currently outstanding common shares. The Company’s existing long-term debt obligation contains covenants and limits the
Company’s ability to pay dividends or make other distributions to stockholders. If the Company experiences delays in product sales growth and completing
its product development and obtaining regulatory approval for its other product candidates and is unable to obtain such additional financing, operations
would need to be scaled back or discontinued.

Note 3 — Summary of Significant Accounting Policies

Basis of Presentation

The  Company  has  prepared  the  accompanying  financial  statements  in  accordance  with  accounting  principles  generally  accepted  in  the  United

States of America (“GAAP”).

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported
amounts  of  assets  and  liabilities,  the  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of
revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these financial statements include, but are not limited
to, provisions for uncollectible receivables, chargebacks and sales returns, valuation of inventories, useful lives of assets and the impairment of property
and  equipment,  the  accrual  of  research  and  development  expenses  and  the  valuation  of  common  stock,  stock  options  and  warrants.  Estimates  are
periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become
known. Actual results could differ from those estimates or assumptions.

Segment Information

The  Company  operates  the  business  on  the  basis  of  a  single  reportable  segment,  which  is  the  business  of  developing  and  commercializing
prescription drug products. The Company’s chief operating decision-maker is the Chief Executive Officer (“CEO”), who evaluates the Company as a single
operating segment.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. All cash and cash
equivalents  are  held  in  U.S.  financial  institutions  or  invested  in  short-term  U.S.  treasury  bills.  Cash  equivalents  consist  of  an  interest-bearing  checking
account and a U.S. treasury bill. From time to time, amounts deposited with its bank exceed federally insured limits. The Company believes the associated
credit risk to be minimal.

Accounts Receivable

Accounts  receivable  are  recorded  at  the  invoiced  amount  and  are  non-interest  bearing.  Accounts  receivable  are  recorded  net  of  allowances  for
doubtful accounts, cash discounts for prompt payment, distribution fees, chargebacks and returns and allowances. The total for these reserves amounted to
$96 and $71 as of December 31, 2021 and 2020, respectively.

Inventories

The  Company  values  its  inventories  at  the  lower  of  cost  or  net  realizable  value  using  the  first-in,  first-out  method  of  valuation.  The  Company
reviews its inventories for potential excess or obsolete issues on an ongoing basis and will record a write-down if an impairment is identified. Inventories at
December 31, 2021 and 2020 consist solely of purchased finished goods. At December 31, 2021, inventories are shown net of a slow-moving reserve for its
Biorphen product of $1,414 due to the risk of expiry before this entire stock of inventories is sold. There was an inventory reserve of $1,414 and $623 at
December 31, 2021 and 2020, respectively.

Property and Equipment

Property  and  equipment  are  stated  at  cost.  Depreciation  of  property  and  equipment  is  computed  utilizing  the  straight-line  method  based  on  the
following estimated useful lives. Computer hardware and software is depreciated over three years. Equipment, furniture and fixtures is depreciated over
five years.  Leasehold  improvements  are  amortized  over  their  estimated  useful  lives  or  the  remaining  lease  term,  whichever  is  shorter.  Construction  in
progress is capitalized but not depreciated until it is placed into service.

Maintenance and repairs are charged to expense as incurred, while renewals and improvements are capitalized.

Note 3 — Summary of Significant Accounting Policies (continued)

Intangible Assets

The Company capitalizes payments it makes for licensed products when the payment is based on FDA approval for the product and the cost is
recoverable based on expected future cash flows from the product. The cost is amortized on a straight-line basis over the estimated useful life of the product
commencing  on  the  approval  date  in  accordance  with  Accounting  Standards  Codification  (“ASC”)  350  —  Intangibles  -  Goodwill  and  Other.  A  $750
payment related to the approval of the Company’s Biorphen product in 2019 has been capitalized and that cost is being amortized over five years. A $3,250
payment related to the approval of the Company’s Carglumic Acid product in December 2021 has been capitalized and that cost is being amortized over ten
years. The intangible assets, net on the Company’s balance sheet reflected $379 and $175 of accumulated amortization as of December 31, 2021 and 2020,
respectively. The Company recorded amortization expense of $204, $150 and $25 for the years ended December 31, 2021, 2020 and 2019, respectively, and
will record amortization expense of $475 per year for these intangible assets for 2022 through 2023 and then $450 in 2024 when the Biorphen asset will be
fully amortized. For 2025 through 2030, the Company will incur amortization expense of $325 and then $271 in 2031 when the Carglumic Acid asset will
be fully amortized.

Impairment of Long-Lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted
future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is
recognized in the Company’s statements of operations for the amount by which the carrying amount of the asset exceeds the fair value of the asset. No
impairment was recognized during the years ended December 31, 2021, 2020 and 2019.

Debt Issuance Costs and Debt Discount and Detachable Debt-Related Warrants

Costs  incurred  to  issue  debt  are  deferred  and  recorded  as  a  reduction  to  the  debt  balance  in  the  accompanying  balance  sheets.  The  Company
amortizes debt issuance costs over the expected term of the related debt using the effective interest method. Debt discounts relate to the relative fair value
of warrants issued in conjunction with the debt and are also recorded as a reduction to the debt balance and accreted over the expected term of the debt to
interest expense using the effective interest method.

Note 3 — Summary of Significant Accounting Policies (continued)

Leases

The Company accounts for leases in accordance with ASC Topic 842 — Leases. The Company reviews all relevant facts and circumstances of a
contract  to  determine  if  it  is  a  lease  whereby  the  terms  of  the  agreement  convey  the  right  to  control  the  direct  use  and  receive  substantially  all  of  the
economic  benefits  of  an  identified  asset  for  a  period  of  time  in  exchange  for  consideration.  The  associated  right-of-use  assets  and  lease  liabilities  are
recognized  at  lease  commencement.  The  Company  measures  lease  liabilities  based  on  the  present  value  of  the  lease  payments  over  the  lease  term
discounted using the rate it would pay on a loan with the equivalent payments and term for the lease. The Company does not include the impact for lease
term options that would extend or terminate the lease unless it is reasonably certain that it will exercise any such options. The Company accounts for the
lease components separately from non-lease components for its operating leases.

The Company measures right-of-use assets based on the corresponding lease liabilities adjusted for (i) any prepayments made to the lessor at or
before  the  commencement  date,  (ii)  initial  direct  costs  it  incurs,  and  (iii)  any  incentives  under  the  lease.  In  addition,  the  Company  evaluates  the
recoverability of its right-of-use assets for possible impairment in accordance with its long-lived assets policy.

Operating leases are reflected on the balance sheets as operating lease right-of-use assets, current accrued liabilities and long-term operating lease

liabilities. The Company does not have any finance leases as of December 31, 2021 and 2020.

The Company commences recognizing operating lease expense when the lessor makes the underlying asset available for use by the Company and

the operating lease expense is recognized on a straight-line basis. Variable lease payments are expensed as incurred.

The  Company  does  not  recognize  right-of-use  assets  or  lease  liabilities  for  leases  with  a  term  of  twelve  months  or  less;  such  lease  costs  are

recorded in the statements of operations on a straight-line basis over the lease term.

Patent Costs

All  patent-related  costs  incurred  in  connection  with  filing  and  prosecuting  patent  applications  are  expensed  as  incurred  due  to  the  uncertainty

about the successful award of a patent and the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses.

Concentrations of Credit Risk, Sources of Supply and Significant Customers

The Company is subject to credit risk for its cash and cash equivalents which are invested in money market funds and U.S. treasury bills from time
to time. The Company maintains its cash and cash equivalent balances with one major commercial bank and the deposits held with the financial institution
exceed the amount of insurance provided on such deposits and is exposed to credit risk in the event of a default by the financial institutions holding its cash
and cash equivalents to the extent recorded on the balance sheets.

The  Company  is  dependent  on  third-party  suppliers  for  its  products  and  product  candidates.  In  particular,  the  Company  relies,  and  expects  to
continue  to  rely,  on  a  small  number  of  suppliers  to  manufacture  key  chemicals,  approved  products  and  process  its  product  candidates  as  part  of  its
development programs. These programs could be adversely affected by a significant interruption in the manufacturing process.

Note 3 — Summary of Significant Accounting Policies (continued)

The Company is also subject to credit risk from its accounts receivable related to product sales as it extends credit based on an evaluation of the
customer’s  financial  condition,  and  collateral  is  not  required.  Management  monitors  its  exposure  to  accounts  receivable  by  periodically  evaluating  the
collectability of the account receivable based on a variety of factors including the length of time the receivables are past due, the financial health of the
customer and historical experience. Based upon the review of these factors, the Company recorded no allowance for doubtful accounts at December 31,
2021 or 2020. The accounts receivable balance at December 31, 2021 and 2020 and product sales revenue recognized during the year ended December 31,
2021 and 2020 consist of sales to and amounts due from AmerisourceBergen Corporation, Cardinal Health Services and McKesson Corporation for sales of
the Company’s Biorphen product. The December 31, 2021 accounts receivable balance and sales in 2021 also include a $5,000 milestone from Azurity, in
accordance with the Eprontia™ (topiramate oral solution) product, amounts due from AnovoRx for sales of the Company’s Alkindi Sprinkle product and
its Carglumic Acid product, which launched in December 2021.

Revenue Recognition for Contracts with Customers

The  Company  accounts  for  contracts  with  its  customers  in  accordance  with  ASC  606  —  Revenue  from  Contracts  with  Customers.  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 which 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.

At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised
within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company
then  recognizes  as  revenue  the  amount  of  the  transaction  price  that  is  allocated  to  the  respective  performance  obligation  when  (or  as)  the  performance
obligation  is  satisfied.  Arrangements  that  include  rights  to  additional  goods  or  services  that  are  exercisable  at  a  customer’s  discretion  are  generally
considered  options.  The  Company  assesses  whether  these  options  provide  a  material  right  to  the  customer  and,  if  so,  they  are  considered  performance
obligations. The exercise of a material right is accounted for as a contract modification for accounting purposes.

The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as)
each performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method. Any amounts
received  prior  to  revenue  recognition  will  be  recorded  as  deferred  revenue.  Amounts  expected  to  be  recognized  as  revenue  within  the  twelve  months
following the balance sheet date will be classified as current portion of deferred revenue in the Company’s balance sheets. Amounts not expected to be
recognized as revenue within the twelve months following the balance sheet date are classified as long-term deferred revenue, net of current portion.

Milestone Payments – If a commercial contract arrangement includes development and regulatory milestone payments, the Company will evaluate
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. Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, are generally not
considered probable of being achieved until those approvals are received.

Note 3 — Summary of Significant Accounting Policies (continued)

Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a
customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, the Company will recognize
revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has
been satisfied or partially satisfied. To date, the Company has not recognized any royalty revenue resulting from any of its licensing arrangements.

Significant Financing Component – In determining the transaction price, the Company will adjust consideration for the effects of the time value of
money if the expected period between payment by the licensees and the transfer of the promised goods or services to the licensees will be more than one
year.

The  Company  sells  Biorphen  in  the  U.S.  to  wholesale  pharmaceutical  distributors,  who  then  sell  the  product  to  hospitals  and  other  end-user
customers. Sales to wholesalers are made pursuant to purchase orders subject to the terms of a master agreement, and delivery of individual shipments of
Biorphen  represent  performance  obligations  under  each  purchase  order.  The  Company  uses  a  third-party  logistics  (“3PL”)  vendor  to  process  and  fulfill
orders and has concluded it is the principal in the sales to wholesalers because it controls access to the 3PL vendor services rendered and directs the 3PL
vendor  activities.  The  Company  has  no  significant  obligations  to  wholesalers  to  generate  pull-through  sales.  In  addition,  the  Company  sells  its  Alkindi
Sprinkle and Carglumic Acid product to one pharmacy distributor customer which provides order fulfilment and inventory storage/distribution services.

Selling prices initially billed to wholesalers are subject to discounts for prompt payment and subsequent chargebacks when the wholesalers sell
Biorphen  at  negotiated  discounted  prices  to  members  of  certain  group  purchasing  organizations  (“GPOs”)  and  government  programs.  In  addition,  the
Company  pays  fees  to  wholesalers  for  their  distribution  services,  inventory  reporting  and  chargeback  processing.  The  Company  pays  GPOs  fees  for
administrative services and for access to GPO members and concluded the benefits received in exchange for these fees are not distinct from its sales of
Biorphen, and accordingly it applies these amounts to reduce revenues. Wholesalers also have rights to return unsold product nearing or past the expiration
date. Because of the shelf life of Biorphen and the Company’s lengthy return period, there may be a significant period of time between when the product is
shipped and when it issues credits on returned product. For its Alkindi Sprinkle and Carglumic Acid products, the Company bills at the initial product list
price  which  are  subject  to  offsets  for  patient  co-pay  assistance  and  potential  state  Medicaid  reimbursements  which  are  recorded  as  a  reduction  of  net
revenues at the date of sale/shipment.

The Company estimates the transaction price when it receives each purchase order taking into account the expected reductions of the selling price
initially billed to the wholesaler/distributor arising from all of the above factors. The Company has developed estimates for future returns and chargebacks
of Biorphen and the impact of the other discounts and fees it pays while Alkindi Sprinkle and Carglumic Acid sales to its distributor are not subject to
returns. When estimating these adjustments to the transaction price, the Company reduces it sufficiently to be able to assert that it is probable that there will
be no significant reversal of revenue when the ultimate adjustment amounts are known.

The Company recognizes revenue from Biorphen product sales and related cost of sales upon product delivery to the wholesaler location. At that
time,  the  wholesalers  take  control  of  the  product  as  they  take  title,  bear  the  risk  of  loss  of  ownership,  and  have  an  enforceable  obligation  to  pay  the
Company. They also have the ability to direct sales of product to their customers on terms and at prices they negotiate. Although wholesalers have product
return rights, the Company does not believe they have a significant incentive to return the product. The Company stores its Alkindi Sprinkle and Carglumic
Acid inventory at its pharmacy distributor customer location and sales are recorded when stock is pulled and shipped to fulfill specific patient orders.

Upon  recognition  of  revenue  from  product  sales,  the  estimated  amounts  of  credit  for  product  returns,  chargebacks,  distribution  fees,  prompt
payment discounts, state Medicaid and GPO fees are included in sales reserves, accrued liabilities and net of accounts receivable. The Company monitors
actual product returns, chargebacks, discounts and fees subsequent to the sale. If these amounts end up differing from its estimates, it will make adjustments
to these allowances, which are applied to increase or reduce product sales revenue and earnings in the period of adjustment.

In addition, the Company anticipates it will receive revenues from product licensing agreements where it has contracted for milestone payments

and royalties from products it has developed or for which it has acquired the rights to a product developed by a third party.

Note 3 — Summary of Significant Accounting Policies (continued)

Cost of Product Sales

Cost of product sales consists of the profit-sharing and royalty fees with the Company’s product licensing and development partners, the purchase
costs for finished products from third-party manufacturers and freight and handling/storage costs from the Company’s 3PL logistics service providers. The
cost of sales for profit-sharing and royalty fees and costs for purchased finished products and the associated inbound freight expense is recorded when the
associated  product  sale  revenue  is  recognized  in  accordance  with  the  terms  of  shipment  to  customers  while  outbound  freight  and  handling/storage  fees
charged  by  the  3PL  service  provider  are  expensed  as  they  are  incurred.  Cost  of  sales  also  reflects  any  write-downs  or  reserve  adjustments  for  the
Company’s inventories.

Research and Development Expenses

Research  and  development  (“R&D”)  expenses  include  both  internal  R&D  activities  and  external  contracted  services.  Internal  R&D  activity
expenses include salaries, benefits and stock-based compensation and other costs to support the Company’s R&D operations. External contracted services
include  product  development  efforts  such  as  certain  product  licensor  milestone  payments,  clinical  trial  activities,  manufacturing  and  control-related
activities and regulatory costs. R&D expenses are charged to operations as incurred. The Company reviews and accrues R&D expenses based on services
performed and relies upon estimates of those costs applicable to the stage of completion of each project. Significant judgments and estimates are made in
determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates.

Upfront payments and milestone payments made for the licensing of technology for products that are not yet approved by the FDA are expensed
as  R&D  in  the  period  in  which  they  are  incurred.  Nonrefundable  advance  payments  for  goods  or  services  to  be  received  in  the  future  for  use  in  R&D
activities are recorded as prepaid expenses and are expensed as the related goods are delivered or the services are performed.

Earnings (Loss) Per Share

Basic net loss per common share is computed by dividing net loss attributable to common stockholders for the period by the weighted average
number  of  common  shares  outstanding  during  the  period.  Diluted  net  loss  per  share  is  computed  by  dividing  the  net  loss  attributable  to  common
stockholders for the period by the weighted average number of common and common equivalent shares, such as Series A Preferred, unvested restricted
stock,  stock  options  and  warrants  that  are  outstanding  during  the  period.  Common  stock  equivalents  are  excluded  from  the  computation  when  their
inclusion would be anti-dilutive. No such adjustments were made for 2021, 2020 or 2019 as the Company reported a net loss for the years ended December
31, 2021, 2020 and 2019 and including the effects of common stock equivalents in the diluted earnings per share calculation would have been anti-dilutive
(see Note 9). Basic weighted average shares for the year ended December 31, 2021 include 600,000 vested warrants to purchase common shares. As the
shares underlying these warrants can be purchased for little to no consideration ($0.01 per share exercise price), they are included in the computation of
basic earnings per share.

Stock-Based Compensation

The Company accounts for stock-based compensation under the provisions of ASC — 718 Compensation — Stock Compensation. The guidance under
ASC 718 requires companies to estimate the fair value of the stock-based compensation awards on the date of grant and record expense over the related
service periods, which are generally the vesting period of the equity awards. The Company estimates the fair value of stock-based option awards using the
Black-Scholes-Merton option-pricing model (“BSM”). The BSM requires the input of subjective assumptions, including the expected stock price volatility,
the  calculation  of  expected  term,  forfeitures  and  the  fair  value  of  the  underlying  common  stock  on  the  date  of  grant,  among  other  inputs.  The  risk-free
interest rate was determined from the implied yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of the
options or warrants. Dividends on common stock are assumed to be zero for the BSM valuation of the stock options. The expected term of stock options
granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable companies’ historical volatility
along with a limited weighting included for the Company’s own volatility, which management believes represents the most accurate basis for estimating
expected future volatility under the current conditions. The Company accounts for forfeitures as they occur. The Company uses the closing common stock
price on the date of grant for the fair value of the common stock.

Income Taxes

As part of the process of preparing the Company’s financial statements, the Company must estimate the actual current tax liabilities and assess
temporary  differences  resulting  from  differing  treatment  of  items  for  tax  and  accounting  purposes.  These  differences  result  in  deferred  tax  assets  and
liabilities, which are included within the balance sheets. The Company must assess the likelihood that the deferred tax assets will be recovered from future
taxable income and, to the extent the Company believes that recovery is not likely, a valuation allowance must be established. To the extent the Company
establishes a valuation allowance or increase or decrease to this allowance in a period, the impact will be included in income tax expense in the statements
of operations. As of December 31, 2021 and 2020, the Company has established a 100% valuation reserve against its deferred tax assets.

The Company accounts for income taxes under the provisions of ASC 740 - Income Taxes. As of December 31, 2021 and 2020, there were no
unrecognized tax benefits included in the balance sheets that would, if recognized, affect the effective tax rate. The Company’s practice is to recognize
interest and penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties in its balance sheets at
December 31, 2021 or 2020, and has not recognized interest and penalties in the statements of operations for the years ended December 31, 2021, 2020 and
2019. As of December 31, 2021, the Company is subject to taxation in the United States and certain individual states – primarily Illinois and Tennessee.
The Company’s tax losses from 2017 through 2021 are subject to examination by the federal and state tax authorities due to the carryforward of unutilized
net operating losses (“NOLs”).

Current  accounting  standards  include  guidance  on  the  accounting  for  uncertainty  in  income  taxes  recognized  in  the  financial  statements.  Such
standards also prescribe a recognition threshold and measurement model for the financial statement recognition of a tax position taken, or expected to be
taken, and provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company
believes that the ultimate deductibility of all tax positions is highly certain, although there is uncertainty about the timing of such deductibility. As a result,
no liability for uncertain tax positions was recorded as of December 31, 2021 or 2020.

Fair Value Measurements

We  measure  certain  of  our  assets  and  liabilities  at  fair  value.  Fair  value  represents  the  price  that  would  be  received  to  sell  an  asset  or  paid  to
transfer  a  liability  in  an  orderly  transaction  between  market  participants  at  the  measurement  date.  Fair  value  accounting  requires  characterization  of  the
inputs used to measure fair value into a three-level fair value hierarchy as follows:

Level 1 — Inputs based on quoted prices in active markets for identical assets or liabilities. An active market is a market in which transactions

occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 — Observable inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market

data obtained from sources independent from the entity.

Level 3 — Unobservable inputs that reflect the entity’s own assumptions about the assumptions market participants would use in pricing the asset

or liability developed based on the best information available.

Fair value measurements are classified based on the lowest level of input that is significant to the measurement. The Company’s assessment of the
significance  of  a  particular  input  to  the  fair  value  measurement  requires  judgment,  which  may  affect  the  valuation  of  the  assets  and  liabilities  and  their
placement  within  the  fair  value  hierarchy  levels.  The  determination  of  the  fair  values  stated  below  takes  into  account  the  market  for  the  Company’s
financials,  assets  and  liabilities,  the  associated  credit  risk  and  other  factors  as  required.  The  Company  considers  active  markets  as  those  in  which
transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

The Company’s financial instruments included cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, PPP loan and
long-term debt obligation. The carrying amounts of these financial instruments, except for the PPP loan and long-term debt obligation, approximate their
fair values due to the short-term maturities of these instruments. Based on borrowing rates currently available to the Company, the carrying value of the
PPP loan and long-term debt obligation approximate their respective fair values.

Impact of New Accounting Pronouncements

There  were  no  new  accounting  pronouncements  issued  by  the  FASB  during  the  current  period  that  would  apply  to  the  Company  and  have  a

material impact on its financial position or results of operations.

Note 5 – Debt

SWK Loan

On November 13, 2019, the Company entered into a credit agreement (the “SWK Credit Agreement”) with SWK Holdings Corporation (“SWK”)
which provided for up to $10,000 in financing. The Company received proceeds of $5,000 at closing and was able to borrow an additional $5,000 upon the
FDA approval of a second product developed by the Company, excluding EM-100. In March 2020, in conjunction with the Company’s Alkindi Sprinkle
product licensing agreement (see Note 14) and the Company’s March 2020 sale of additional shares of its common stock (see Note 6), the Company and
SWK amended the SWK Credit Agreement. The amendment provided the Company with the option to immediately draw $2,000 and the ability to borrow
an additional $3,000 based upon the FDA approval of EM-100 and Alkindi Sprinkle which subsequently occurred in September 2020. Accordingly, the
Company borrowed an additional $2,000 on August 11, 2020. The term of the SWK Credit Agreement is for five years and borrowings bear interest at a
rate of LIBOR 3-month plus 10.0%, subject to a stated LIBOR floor rate of 2.0%. A 2.0% unused credit limit fee is assessed during the first twelve months
after the date of the SWK Credit Agreement and loan fees include a 5.0% exit fee based on the principal amounts drawn which is payable at the end of the
term of the SWK Credit Agreement. The Company is required to maintain a minimum cash balance of $3,000, only pay interest on the debt until February
2022 and then pay 5.5% of the loan principal balance commencing on February 15, 2022 and then every three months thereafter until November 13, 2024
at which time the remaining principal balance is due. Borrowings under the SWK Credit Agreement are secured by the Company’s assets. The SWK Credit
Agreement contains customary default provisions and covenants which include limits on additional indebtedness. In March 2020, SWK provided a waiver
for the Company to obtain loans with the Small Business Association. In February 2021, the Company notified SWK that it will not require additional
borrowing capacity under the SWK Credit Agreement and terminated the additional borrowing capacity with SWK.

In  connection  with  the  initial  $5,000  borrowed  in  November  2019,  the  Company  issued  warrants  to  SWK  to  purchase  51,239  shares  of  the
Company’s common stock with an exercise price of $5.86 per share. The relative fair value of these 51,239 warrants was $226 and was estimated using the
Black-Scholes-Merton option pricing model with the following assumptions: fair value of the Company’s common stock at issuance of $5.75  per  share;
seven-year contractual term; 95% volatility; 0% dividend rate; and a risk-free interest rate of 1.8%.

In connection with the additional $2,000 borrowed in August 2020, the Company issued warrants for 18,141 shares of its common stock at an
exercise price of $6.62 per share. The relative fair value of the 18,141 warrants was $94 and was estimated using the Black-Scholes-Merton option pricing
model  with  the  following  assumptions:  fair  value  of  the  Company’s  common  stock  at  issuance  of  $6.85  per  share;  seven-year  contractual  term;  95%
volatility; 0% dividend rate; and a risk-free interest rate of 0.4%.

These warrants (the “SWK Warrants”) are exercisable immediately and have a term of seven years from the date of issuance. The SWK Warrants
are subject to a cashless exercise feature, with the exercise price and number of shares issuable upon exercise subject to change in connection with stock
splits, dividends, reclassifications and other conditions.

The  Company  recorded  interest  expense  of  $1,042, $884  and  $98  in  2021,  2020  and  2019,  respectively,  which  included  $148  $121  and  $16,
respectively, of debt discount amortization. The Company had accrued interest of $134 and $48 as of December 31, 2021 and 2020, respectively, which is
included in accrued liabilities in the accompanying balance sheets.

Plan”), which authorized the issuance of up to 5,000,000 shares of the Company’s common stock. In conjunction with the Company’s IPO in November
2018, the Company’s stockholders and board of directors approved the 2018 Equity Incentive Plan, as amended (the “2018 Plan”) which succeeded the
2017 Plan. The Company has granted RSAs, stock options and RSUs for its common stock under the 2017 Plan and 2018 Plan as detailed in the tables

Shares that are expired, terminated, surrendered or canceled without having been fully exercised will be available for future awards under the 2018
Plan. In addition, the 2018 Plan provides that commencing January 1, 2019 and through January 1, 2028, the share reserve will be increased by 4% of the
total  number  of  shares  outstanding  as  of  the  preceding  December  31,  subject  to  a  reduction  at  the  discretion  of  the  Company’s  board  of  directors.  On

In April 2020, the Company issued 15,190 shares of its common stock as an RSA to a new employee. This RSA vested 25% every three months

and was 100% vested in April 2021.

To date, all stock options issued have been non-qualified stock options and the exercise prices were set at the fair value for the shares at the dates
of  grant.  Options  generally  have  a  ten-year  life,  except  for  options  to  purchase  50,000  shares  of  the  Company’s  common  stock  granted  to  product
consultants  that  expire  within  five years  if  the  Company  is  not  able  to  successfully  file  certain  product  submissions  to  the  FDA  prior  to  the  five-year
expiration date. Furthermore, these option awards to the Company’s product consultants do not vest unless certain product submissions are made to the
FDA, and accordingly, the Company has not recorded any expense for these contingently vesting option awards to its product consultants.

For the years ended December 31, 2021, 2020, and 2019, the Company’s total stock-based compensation expense was $3,381, $2,576 and $1,888,

Note 8 — Share-Based Payment Awards (continued)

Expected Term — The Company has opted to use the “simplified method” for estimating the expected term of options granted to employees and
directors, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of the option (generally 10 years).
The expected term of options granted to non-employees equals the contractual life of the options.

Expected Volatility — Due to the Company’s limited operating history and a lack of Company-specific historical and implied volatility data, the
Company has based its estimate of expected volatility on the historical volatility of a group of similar companies that are publicly traded. The historical
volatility data was computed using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term
of the stock-based awards. The Company has also applied some limited weighting to its own volatility.

Risk-Free Interest Rate — The risk-free rate assumption is based on the U.S. Treasury instruments with maturities similar to the expected term of

the Company’s stock options.

Expected Dividend — The Company has not issued any dividends in its history and does not expect to issue dividends over the life of the options

and therefore has estimated the dividend yield to be zero.

Fair value of Common Stock —The Company uses the closing stock price on the date of grant for the fair value of the common stock.

Note 8 — Share-Based Payment Awards (continued)

In December 2018, the Company’s board of directors adopted an initial offering of the Company’s common stock under the Company’s ESPP. The
Company’s ESPP provides for an initial reserve of 150,000 shares and this reserve is automatically increased on January 1 of each year by the lesser of 1%
of the outstanding common shares at December 31 of the preceding year or 150,000 shares, subject to reduction at the discretion of the Company’s board of
directors.

The initial offering began on December 17, 2018 and ended on December 10, 2019. The initial offering consisted of two purchase periods, with
the first purchase period ended on June 10, 2019 and the second purchase period ended on December 10, 2019. The terms of the ESPP permit employees of
the Company to use payroll deductions to purchase stock at a price per share that is at least the lesser of (1) 85% of the fair market value of a share of
common stock on the first date of an offering or (2) 85% of the fair market value of a share of common stock on the date of purchase. After the initial
offering period, subsequent twelve-month offering periods automatically commence over the term of the ESPP on the day that immediately follows the
conclusion  of  the  preceding  offering,  each  consisting  of  two  purchase  periods  approximately  six  months  in  duration  ending  on  or  around  June  10  and
December 10 each year, subject to a restart feature if the Company’s stock price drops at the end of a six-month period within the twelve-month offering
period.

The Company recorded an expense of $73, $71 and $112 in 2021, 2020 and 2019, respectively, related to the ESPP. The weighted average grant
date fair value of share awards in 2021, 2020 and 2019 was $2.50, $2.32 and $2.56 per share, respectively. Employees contributed $205 and $115 to the
ESPP during 2021 and 2020, respectively. Of these amounts, $22 and $18 at December 31, 2021 and 2020, respectively, is included in accrued liabilities in
the accompanying balance sheets.

Note 9 — Basic and Diluted Net Loss per Common Share

Basic and diluted net loss per share is computed using the weighted average number of shares of common stock outstanding during the period.
Common stock equivalents (using the treasury stock and “if converted” method) from stock options, unvested RSAs and RSUs, and warrants at December
31, 2021, 2020 and 2019 were 4,286,687, 3,371,489 and 3,590,465, respectively, and are excluded from the calculation of diluted net loss per share because
the effect is anti-dilutive. Included in the basic and diluted net loss per share calculation were RSUs awarded to directors that had vested, but the issuance
and delivery of the shares are deferred until the director retires from service as a director.

The following table shows the computation of basic and diluted net loss per common share:

Harrow

Harrow was issued 3,500,000 shares of the Company’s common stock at the formation of the Company at the $0.001 par value per share price as
the paid-in-capital contribution from Harrow. In April 2021, Harrow sold 1,518,000 shares of the Eton common stock it owned in an underwritten public
offering. As of December 31, 2021, Harrow owned 1,982,000 shares of Eton’s common shares which represents 8.0% of the Company’s common shares
outstanding. The Company and Harrow signed licensing agreements for two products developed by Harrow whereby Harrow assigned the product rights to
the Company. In July 2018, the Company determined that one of the products was not viable for its portfolio of product opportunities and cancelled the
licensing agreement whereby Harrow retains the product rights.

On May 6, 2019, the Company entered into an Asset Purchase Agreement (the “CT-100 Asset Purchase Agreement”) with Harrow. Pursuant to the
CT-100 Asset Purchase Agreement, the Company sold all of its right, title and interest in CT-100 to Harrow, including any such product that incorporates or
utilizes  its  intellectual  property  rights  (a  “Product”  or,  collectively,  “Products”).  Pursuant  to  the  CT-100  Asset  Purchase  Agreement,  Harrow  will  make
certain  payments  to  the  Company  upon  the  achievement  of  certain  development  and  commercial  milestones.  In  addition,  Harrow  is  required  to  pay  the
Company a royalty in the low-single digit percentage range worldwide on a country-by-country basis on net sales for a period of the longer of 15 years
from the date of the first commercial sale of a product in a particular country or the time that a valid intellectual property claim on such Product remains in
force in the applicable country. The CT-100 Asset Purchase Agreement also contains customary representations, warranties, covenants and indemnities by
the parties. To date, there have not been any sales of the CT-100 product and therefore no earned royalties to the Company for this product.

Additionally, the Chief Executive Officer of Harrow was a member of the Company’s board of directors until March 17, 2021 when he retired
from  service  with  the  board.  The  Company  issued  25,000  shares  to  the  Harrow  CEO  in  April  2021  after  his  retirement  from  the  Company’s  board
associated with RSU’s that were previously fully vested.

In late March 2021, the Company closed its laboratory operation in Lake Zurich, Illinois and in May 2021 it reached an agreement for Imprimis

Pharmaceuticals, a subsidiary of Harrow, to purchase its lab equipment for $700 which was $181 above the Company’s net book value of the equipment.

Chief Executive Officer

The CEO has a partial interest in a company that the Company has partnered with for its EM-100 product as described below.

The  Company  acquired  the  exclusive  rights  to  sell  the  EM-100  product  in  the  United  States  pursuant  to  a  sales  and  marketing  agreement  (the
“Eyemax Agreement”) dated August 11, 2017 between the Company and Eyemax LLC (“Eyemax”), an entity affiliated with the Company’s CEO. The
Company also held a right of first refusal to obtain the exclusive license rights for geographic areas outside of the United States. Pursuant to the Eyemax
Agreement,  the  Company  was  responsible  for  all  costs  of  testing  and  FDA  approval  of  the  product,  other  than  the  FDA  filing  fee  which  was  paid  by
Eyemax. The Company was also to be responsible for commercializing the product in the United States at its expense. The Company paid Eyemax $250
upon execution of the Eyemax Agreement, which was recorded as a component of R&D expense. Under the terms of the original agreement, the Company
would pay Eyemax $250 upon FDA approval and $500 upon the first commercial sale of the product and pay Eyemax a royalty of 10% on the net sales of
all products. The Eyemax Agreement was for an initial term of 10 years from the date of the Eyemax Agreement, subject to successive two-year renewals
unless the Company elected to terminate the Eyemax Agreement. There were no amounts due under the terms of the Eyemax Agreement as of December
31, 2021 or 2020.

Note 10 — Related Party Transactions (continued)

On  February  18,  2019,  the  Company  entered  into  an  Amended  and  Restated  Agreement  with  Eyemax  amending  the  Sales  Agreement  (the
“Amended Agreement”). Pursuant to the Amended Agreement, Eyemax sold the Company all of its right, title and interest in EM-100, including any such
product  that  incorporates  or  utilizes  Eyemax’s  intellectual  property  rights.  Under  the  Amended  Agreement,  the  Company  assumed  certain  liabilities  of
Eyemax  under  its  Exclusive  Development  &  Supply  Agreement  with  Excelvision  SAS  dated  as  of  July  11,  2013,  as  amended  (the  “Excelvision
Agreement”), with respect to certain territories and arising during certain time periods. Pursuant to the Amended Agreement, the Company paid Eyemax
two milestone payments: (i) one milestone payment for $250 upon regulatory approval in the territory by the FDA of the first single agent product and (ii)
one milestone payment for $500 following the first commercial sale of the first single agent product in the territory. Following payment of the milestones,
the Company is entitled to retain all of the non-royalty transaction revenues and royalties up to $2,000 (the “Recovery Amount”). After the Company has
retained the full Recovery Amount, it is entitled to retain half of all royalty and non-royalty transaction revenue. The Company has realized $1,735 of the
non-royalty and royalty revenue as of December 31, 2021. The Amended Agreement also contains customary representations, warranties, covenants and
indemnities  by  the  parties.  The  EM-100  asset  and  its  associated  product  rights  were  sold  to  Bausch  Health  on  February  18,  2019  and  future  potential
royalties of twelve percent on Bausch Health sales of EM-100, which was approved by the FDA in September 2020, will be split between Eyemax and the
Company. The royalty from Bausch Health is subject to reduction if a competitive product with the same active pharmaceutical ingredient is launched in
the U.S. or if the EM-100 U.S market share falls below a specified target percentage. There were no amounts due Eyemax under the terms of the Amended
Agreement as of December 31, 2021 or 2020.

Note 11 — Leases

The Company recognizes a right-of-use (“ROU”) asset and a lease liability on the balance sheet for substantially all leases, including operating

leases, and separates lease components from non-lease components related to its office space lease.

On January 12, 2018, the Company signed an amended lease agreement to lease additional office space adjacent to its current corporate office
space in Deer Park, Illinois. The amended lease was scheduled to expire at the end of March 2021. In October 2020, the Company renewed its office lease
for a two-year period through March 31, 2023 and recorded $195 in ROU assets and $195 in operating lease liabilities associate with the lease extension.
On March 7, 2018, the Company entered into a lease for laboratory space at a complex in Lake Zurich, Illinois. The lease commenced on March 7, 2018
and was scheduled to expire in February 2021. In November 2020, this laboratory lease was extended to June 2021 and was not extended after that date as
the Company completed an evaluation its laboratory operations requirements and determined it would discontinue the laboratory activities and outsource its
requirements.

The Company does not have any lease contracts that contain: (1) an option to extend that the Company is reasonably certain to exercise, (2) an
option to terminate that the Company is reasonably certain to exercise, or (3) an option to extend (or not to terminate) in which exercise of the option is
controlled  by  the  lessor.  Additionally,  the  Company  does  not  have  any  leases  with  residual  value  guarantees  or  material  restrictive  covenants.  Lease
liabilities and their corresponding right-of-use assets have been recorded based on the present value of the future lease payments over the expected lease
term. One of the Company’s lease agreements contains provisions for escalating rent payments over the term of the lease.

The Company’s leases do not contain readily determinable implicit discount rates, and therefore, the Company was required to use its incremental
borrowing rate of 7.8% to discount the future lease payments based on information available at lease commencement. In October 2020, the new discount
rate  for  the  office  lease  extension  was  estimated  at  5.4%.  The  incremental  borrowing  rate  was  estimated  by  determining  the  rate  of  interest  that  the
Company  would  have  to  pay  to  borrow  on  a  collateralized  basis  over  a  similar  term  an  amount  equal  to  the  lease  payments  in  a  similar  economic
environment.

For the years ended December 31, 2021, 2020 and 2019, the Company recorded $113, $139, and $140, respectively, in rent expense.

The Company’s operating lease cost as presented in the “Research and Development” and “General and Administrative” captions in the statements
of operations was $9, $55 and $55 and $86, $84 and $85 for  the  years  ended  December  31,  2021,  2020  and  2019,  respectively.  Cash  paid  for  amounts
included in the measurement of operating lease liabilities was $83 and $131 for years ended December 31, 2021 and 2020, respectively. The ROU asset
amortization for years ended December 31, 2021, 2020 and 2019 was $88, $129 and $121, respectively, and is reflected in depreciation and amortization in
the Company’s statements of cash flows. As of December 31, 2021, the weighted-average remaining lease term was 1.25 years, and the weighted-average
discount rate was 5.4%.

Legal

The  Company  is  subject  to  legal  proceedings  and  claims  that  may  arise  in  the  ordinary  course  of  business.  The  Company  is  not  aware  of  any

pending or threatened litigation matters at this time that may have a material impact on the operations of the Company.

License and Product Development Agreements

The Company has entered into various agreements in addition to those discussed above which are described below.

The Company acquired the exclusive rights to sell the Cysteine injection product in the United States pursuant to a sales and marketing agreement
dated  November  17,  2017  with  an  unaffiliated  third  party  (the  “Sales  Agreement”).  Pursuant  to  the  Sales  Agreement,  the  licensor  is  responsible  for
obtaining FDA approval, at its expense, and the Company is responsible for commercializing the product in the United States at its expense. The Company
was  to  pay  the  third  party  50%  of  the  net  profit  from  the  sale  of  the  product,  however,  in  February  2020,  it  executed  an  amendment  to  the  Sales  and
Marketing  Agreement.  Under  the  revised  terms,  the  Company  will  be  responsible  for  paragraph  IV  related  litigation  and  will  be  entitled  to  62.5%  of
product profit. The initial term is for the first 10 years following the first commercial sale of the product.

On February 8, 2019, the Company entered into an Exclusive Licensing and Supply Agreement (the “ET-202 License Agreement”) with Sintetica
SA  (“Sintetica”)  for  marketing  rights  in  the  United  States  to  Biorphen®  which  is  used  for  the  treatment  of  clinically  important  hypotension  resulting
primarily from vasodilation in the setting of anesthesia. The product was submitted to the FDA for review and subsequently received FDA approval on
October 21, 2019. Pursuant to the terms of the ET-202 License Agreement, the Company is responsible for marketing activities and Sintetica is responsible
for  development,  manufacturing,  and  the  regulatory  activities  related  to  approval.  The  Company  paid  Sintetica  a  licensing  payment  of  $2,000  upon
execution  of  the  ET-202  License  Agreement  and  $750  upon  the  commencement  of  commercial  product  shipments.  Sintetica  supplies  Biorphen  to  the
Company at its direct costs and the Company retains 5% of net sales as a marketing fee. Sintetica is entitled to receive the first $500 of product profits. All
additional profit will be split 50% to the Company and 50% to Sintetica. The ET-202 License Agreement has a ten-year term from the first commercial sale
of Biorphen which occurred in November 2019. There was a gross loss for Biorphen for the years ended December 31, 2021 and 2020 due to slower than
anticipated sales and a product price reduction through the Company’s wholesale customers.

On  February  8,  2019,  the  Company  also  entered  into  an  Exclusive  Licensing  and  Supply  Agreement  (the  “ET-203  License  Agreement”)  with
Sintetica for marketing rights in the United States to ephedrine HCl (brand name Rezipres®), an injectable product candidate for use in the hospital setting.
Pursuant to the terms of the ET-203 License Agreement, the Company will be responsible for marketing activities and Sintetica will be responsible for
development, manufacturing, and regulatory activities related to obtaining regulatory approval. The Company paid Sintetica a licensing payment of $1,000
upon execution of the ET-203 License Agreement which was refunded to Eton in early 2020 due to the FDA not accepting the ET-203 file submission by
Sintetica. The Rezipres product was successfully resubmitted in late 2020 and the Company paid a $600 milestone fee in July 2021 and will pay $750 upon
the commercial sale of the product. Sintetica supplies Rezipres to the Company at its direct costs. The Company will retain 5% of net sales as a marketing
fee. Sintetica will be entitled to receive the first $500 of product profits. All additional profit will be split 50% to the Company and 50% to Sintetica. The
ET-203 License Agreement has a ten-year term from first commercial sale of product.

On January 23, 2019, the Company entered into a Licensing and Supply Agreement (the “Agreement”) with LMW for Zonisamide oral liquid, a
development stage product candidate (“ET-104”). Pursuant to the terms of the Agreement, the Company was to be responsible for regulatory and marketing
activities. LMW will be responsible for development and manufacturing of ET-104. The Company paid the licensor $350 upon execution of the Agreement
and an additional $350 after receiving successful bioequivalence study results, and $325 upon the FDA’s acceptance of the NDA for review and will pay
$325 upon FDA approval of the NDA, $650 upon issuance of patent covering ET-104 listed in the FDA’s Orange Book and $500 in the event that product
sales in excess of $10,000 were achieved within a calendar year. In addition, the Company was required to pay the licensor 35% of the net profit from
product sales. The Agreement was for an initial term of 10 years from the date of the first commercial sale of the product. The Company was to retain sole
ownership of the NDA after expiration of the Agreement.

On  June  12,  2019,  the  Company  entered  into  an  Exclusive  Licensing  and  Supply  Agreement  (the  “ET-105  License  Agreement”)  with Aucta
Pharmaceuticals, Inc. (“Aucta”) for marketing rights in the United States to Lamotrigine, an oral suspension product candidate for use as an adjunct therapy
for partial seizures, primary generalized tonic-clonic seizures, and generalized seizures of Lennox-Gastaut syndrome in patients two years of age and older.
Pursuant to the terms of the ET-105 License Agreement, the Company was to be responsible for marketing activities and Aucta will be responsible for
development, manufacturing, and regulatory activities related to obtaining regulatory approval. The Company paid Aucta a licensing payment of $2,000 in
August 2019 upon receiving an acceptance for review letter from the FDA and will pay $2,450 upon FDA approval and commercial sales of the product
candidate and another $1,000 upon issuance of an Orange-book listed patent. If Aucta successfully completes a Lamotrigine product line extension product,
Eton will pay $1,500 upon FDA acceptance of the product filing, $1,500 upon FDA approval and commercial sales of the extension product candidate and
$450 if the intellectual property for the extension product is transferred to Azurity. Aucta will be entitled to receive milestone payments from the Company
of up to $3,000 based on commercial success of the product, including:

● $1,000 when net sales exceed $10 million in a calendar year
● $2,000 when net sales exceed $20 million in a calendar year

Azurity  will  assume  royalty  or  profit  share  obligations  owed  to  development  partners  as  well  as  additional  milestone  payments  based  on  sales

volume targets.

For the initial licensing milestone fee, the Company paid Diurnal $3,500 in cash and issued 379,474 shares of its common stock to Diurnal which
were valued at $1,264 based on the Company’s closing stock price of $3.33 on March 26, 2020 (see Note 6). The total amount of $4,764 was recorded as a
component of research and development expense in the Company’s statement of operations for the year ended December 31, 2020. The Company will also
pay Diurnal $2,500 if the product obtains orphan drug exclusivity status from the FDA.

On June 15, 2021, the Company acquired U.S. and Canadian rights to Crossject’s ZENEO® hydrocortisone needleless autoinjector, which is under
development as a rescue treatment for adrenal crisis. The Company expects to submit the New Drug Application (NDA) to the FDA in 2023 and plans to
request orphan drug designation. The Company paid Crossject $500 upon signing and could pay up to $4,500 in development milestones and up to $6,000
in commercial milestones, as well as a 10% royalty on net sales.

On  October  28,  2021,  the  Company  acquired  the  U.S.  marketing  rights  to  Carglumic  Acid  Tablets.  The  product’s  Abbreviated  New  Drug
Application (“ANDA”), which is owned by Novitium Pharma, was approved by the FDA on October 12, 2021. The product is an AB-rated, substitutable
generic version of Carbaglu®. The Company paid $3,250 upon signing and will retain 50% of future product profits with the balance being distributed to
the licensor and manufacturer.

Indemnification

As permitted under Delaware law and in accordance with the Company’s Amended and Restated Bylaws, the Company is required to indemnify
its officers and directors for certain events or occurrences while the officer or director is or was serving in such capacity. The Company is also party to
indemnification agreements with its directors and officers. The Company believes the fair value of the indemnification rights and agreements is minimal.
Accordingly, the Company has not recorded any liabilities for these indemnification rights and agreements as of December 31, 2021 or 2020.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

PART II (CONTINUED)

None.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

We  maintain  “disclosure  controls  and  procedures,”  as  such  term  is  defined  in  Rules  13a-15(e)  and  15d-15(e)  under  the  Exchange Act,  that  are
designed  to  ensure  that  information  required  to  be  disclosed  by  us  in  reports  that  we  file  or  submit  under  the  Exchange  Act  is  recorded,  processed,
summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our
management, including our principal executive officer and our principal financial officer, to allow timely decisions regarding required disclosure.

The design of any disclosure controls and procedures 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.

As of December 31, 2021, an evaluation was conducted under the supervision and with the participation of our management, including our Chief
Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures. Based on this evaluation, such officers have
concluded that our disclosure controls and procedures are effective as of December 31, 2021.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for our Company, as such term
is defined in Rule 13a-15(f) under the Exchange Act. Our management conducted an evaluation, with the participation of our principal executive officer
and principal financial officer, of the effectiveness of our internal control over financial reporting as of December 31, 2021, based on the criteria set forth in
the  2013  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  Based  on  this
evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2021.

This report does not include an attestation report of our independent registered public accounting firm regarding our internal control over financial

reporting, in accordance with applicable SEC rules that permit us to provide only management’s report in this report.

Changes in Internal Control over Financial Reporting

There  has  not  been  any  change  in  our  internal  control  over  financial  reporting  (as  defined  in  Rules  13a-15(f)  under  the  Exchange  Act)  that
occurred during the quarter ended December 31, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over
financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our principal executive officer and principal financial officer, do not expect that our disclosure controls or our internal
control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only
reasonable,  not  absolute,  assurance  that  the  control  system’s  objectives  will  be  met.  The  design  of  a  control  system  must  reflect  the  fact  that  there  are
resource  constraints,  and  the  benefits  of  controls  must  be  considered  relative  to  their  costs.  Further,  because  of  the  inherent  limitations  in  all  control
systems,  no  evaluation  of  controls  can  provide  absolute  assurance  that  misstatements  due  to  error  or  fraud  will  not  occur  or  that  all  control  issues  and
instances  of  fraud,  if  any,  have  been  detected. These  inherent  limitations  include  the  realities  that  judgments  in  decision-making  can  be  faulty  and  that
breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or
more people, or by management override of the controls. The design of any system of controls is based in part on 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. Projections of
any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions
or deterioration in the degree of compliance with policies or procedures.
