Item 1. Business

Overview

PART I

We  were  formed  in  April  2017  as  a  specialty  pharmaceutical  company  focused  on  developing,  acquiring,  and  commercializing  innovative
pharmaceutical products that fulfill an unmet patient need. We have successfully built a diversified portfolio of high-value pharmaceutical products, primarily
focused on two categories: hospital injectable products and pediatric retail prescription products.

Corporate Strategy

We  plan  to  achieve  our  goal  of  becoming  an  industry  leading  innovative  pharmaceutical  company  by  executing  on  the  commercialization  of
Biorphen®  and  continuing  to  build  our  product  portfolio  through  internal  product  development  and  business  development  activities.  Our  business
development activities primarily target product opportunities with the following characteristics:

Short Time to Market. We seek out innovative products that are FDA approved, under review with the FDA, or have the potential to be commercialized
within 18 months.

Protection from Competition. Product protection typically takes the form of Orange Book listed patents and FDA granted exclusivities, such as orphan
drug exclusivity. Protection can also include challenging to replicate formulations, complex manufacturing, or difficult to source active pharmaceutical
ingredients.

Low Clinical and Regulatory Risk. We pursue product candidates where we can leverage existing safety and efficacy data to reduce the clinical burden
required to receive FDA approval, providing for faster and lower cost product approvals. Typically, our products require only a single Phase 3 trial, a
bioequivalence trial, or literature based clinical data for their New Drug Application (“NDA”) submissions.

Low Commercial Risk. We pursue products that we believe can fulfill a proven unmet need. This may include opportunities to bring products to market
to address markets that are currently relying on unapproved or compounded products.

Product Portfolio

Our  currently  disclosed  product  portfolio  includes  nine  products:  one  commercial  product,  three  products  under  review  with  the  FDA,  and  five

candidates in our late-stage pipeline.

Approved Products

Biorphen  (Phenylephrine  Hydrochloride  Injection).  Biorphen  is  the  first  and  only  FDA-approved  formulation  of  ready-to-use  phenylephrine
injection. Biorphen in indicated for the treatment of clinically important hypotension resulting primarily from vasodilation in the setting of anesthesia. The
product was approved in October 2019 and launched in December 2019.

We  estimate  the  current  market  size  for  ready-to-use  phenylephrine  to  be  more  than  20  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.  We  acquired  U.S.  marketing  rights  to  the  product  from
Sintetica SA (“Sintetica”) in February 2019.

Products Under FDA Review:

ET-105 (Lamotrigine for Oral Suspension). ET-105 is our innovative formulation of lamotrigine to be delivered to patients as an oral suspension.
The  NDA  for  ET-105  has  been  submitted  to  the  FDA  and  is  under  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.

ET-105 is designed to fulfill an unmet need for patients that require precision dosing or have challenges administering oral solid formulations. Due to
Lamotrigine’s weight-based dosing calculation and the required titration dosing upon initiation of treatment, we believe there is a significant need for ET-

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
105’s precision dosing. Currently the lowest strength tablet form of lamotrigine that is widely available is a 5mg tablet. ET-105 is designed to allow dosing in
increments of 1.0mg.

Lamotrigine is currently only approved in oral solid formulations, for which the U.S. market is currently more than $700 million annually according
to  IQVIA  data.  We  acquired  U.S  marketing  rights  to  the  product  from  Aucta  Pharmaceuticals  in  June  2019.  Aucta  has  been  issued  a  patent  on  ET-105’s
innovative formula, which we expect to be listed in the FDA’s Orange Book upon approval. ET-105’s NDA is under review with the FDA. The application
has been assigned a Prescription Drug User Fee Act (PDUFA) target action date of March 17, 2020, however, on February 19, 2020 we disclosed that we
received an FDA request for changes to the Dosage and Administration section of the product’s Prescribing Information to simplify the dosing information
for  intended  users.  The  FDA  has  requested  that  the  company  conduct  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. The company expects the study and its final report to be completed and
submitted to the FDA in 2020.

EM-100 (Ketotifen Ophthalmic Solution).  EM-100  is  a  preservative-free  formulation  of  ketotifen  ophthalmic  solution  for  the  treatment  allergic
conjunctivitis. The product is expected to be the first and only preservative-free ophthalmic product approved for the treatment of allergic conjunctivitis. EM-
100’s  preservative-free  formulation  is  designed  to  deliver  an  improved  comfort  profile  to  patients  compared  to  currently  available  ketotifen  ophthalmic
products that contain preservatives. EM-100 will be sold via the over-the-counter (OTC) 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 EM-100 product rights to Bausch Health (“Bausch”) in February 2019. Bausch Health will be responsible for commercialization of the
product. We are entitled to receive a $1.5 million milestone payment upon launch of the product and will receive a double-digit percentage royalty on the
product’s  net  sales.  Bausch  received  a  Complete  Response  Letter  on  the  product’s  application  in  July  2019  and  responded  in  an  amendment  submitted  in
December 2019. The product has been assigned a target action date in August 2020.

DS-300. DS-300 is an injectable product candidate for which we have submitted an Abbreviated New Drug Application “ANDA” to the FDA. We
originally submitted DS-300 as an NDA under a Rolling Review, however, due to the approval of a competitor’s NDA containing the same active ingredient,
the FDA requested that we resubmit the product as an ANDA. The ANDA was submitted in December 2019 and has been accepted for review by the FDA.
We believe we are the first-to-file ANDA and should be entitled to 180 days of exclusivity if the patent is successfully challenged. The FDA has assigned the
product’s application a target action date in October 2020, however, expected Paragraph IV challenge litigation will delay final FDA approval beyond that
date.

Prior to the approval of the reference product by a third party in 2019, DS-300’s active ingredient was supplied in injectable form as an unapproved
product. Based on the IQVIA date for the current market price and historic volumes for the unapproved product, we believe the market size is more than $65
million annually.

Late-Stage Product Candidates

ET-203. ET-203 is an innovative ready-to-use formulation of a molecule that is currently approved in a concentrated formulation that must be diluted
prior to administration to patients. Hospitals currently purchase non-FDA approved ready-to-use products from compounding facilities, or manually dilute the
products in-house. Our product candidate has been developed in a ready-to-use strength that can be immediately administered to patients, eliminating the need
for calculations and additional dilution steps. We believe that, if approved, ET-203 will offer significant benefits to hospitals over the current compounded
products, including longer shelf-life, reduction of compounding errors, greater sterility assurance, and more consistent supply. ET-203’s NDA was originally
submitted  to  the  FDA  in  July  2019  and  received  a  refuse-to-file  letter.  Our  development  partner,  Sintetica,  expects  to  address  the  FDA’s  concerns  and
resubmit the NDA in 2020.

ET-104.  ET-104  is  an  innovative  oral  liquid  product  candidate  targeting  a  neurological  indication.  ET-104’s  active  ingredient  is  approved  and
marketed in an oral solid formulation, but the active ingredient is not approved by the FDA in liquid form. Currently, patients requiring liquid formulations of
the active ingredient are reliant on compounded products or manually crushing tablets to create liquid solutions. ET-104 is expected to address this significant
unmet patient need. Our development partner filed a patent application on its unique formula in March 2019. We are currently in discussions with the FDA
regarding the application’s pediatric study protocol, and we expect to submit the NDA in 2020. The current market for ET-104’s active ingredient in oral solid
form is more than $65 million annually according to IQVIA.

ET-103.  ET-103  is  a  unique  oral  liquid  formulation  of  levothyroxine  for  the  treatment  of  hypothyroidism.  Currently  levothyroxine  is  delivered
primarily in tablet and capsule form and is one of the most frequently prescribed medications in the United States with more than 5.7 billion tablets and $2.6
billion  prescribed  annually  according  to  IQVIA  data.  We  are  currently  in  discussions  with  the  FDA  regarding  the  products  bioequivalence  data  results  to
ensure  compliance  with  FDA  requirements  prior  to  submission  of  the  NDA.  If  we  receive  agreement  from  the  FDA,  we  expect  the  product’s  NDA  to  be
submitted in the first half of 2020.

DS-100. DS-100 is an injectable product candidate. DS-100’s active ingredient was historically sold in injectable form as an unapproved product, but
a third party recently received FDA approval. Eton is pursuing a different indication than the currently approved product. We expect an NDA for DS-100 to
be submitted in 2020.

ET-101. Is an innovative oral liquid product candidate targeting a neurological condition. ET-101’s active ingredient is approved and marketed in an
oral  solid  formulation,  but  the  active  ingredient  is  not  approved  by  the  FDA  in  liquid  form.  Currently,  patients  requiring  liquid  formulations  of  the  active
ingredient are reliant on compounded products. ET-101 is expected to address this significant unmet patient need. Based on IQVIA data, the U.S. market for
ET-101’s active ingredient in oral solid form is more than $800 million annually. We are currently running a bioequivalence study for the product and expect
to file the NDA in 2020.

4

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our  late-stage  pipeline  only  includes  product  candidates  that  we  believe  can  be  submitted  to  the  FDA  within  twelve-months.  For  competitive

reasons, we typically do not disclose our additional product candidates that are more than twelve months away from NDA submission.

Goals and Strengths

Our goal is to become a leading specialty pharmaceutical company through the introduction of innovative medicines that are affordable and available

to all patients. We believe our competitive strengths include our:

● unique knowledge of the industry, including our ability to identify product opportunities;

● management’s regulatory and development experience, particularly within the 505(b)(2) pathway;

● our portfolio of attractive assets that we believe will enable us to compete effectively in the market;

● management’s experience in business development, M&A, licensing activities and broad industry connections;

● differentiated business model as compared to generic and branded specialty pharmaceutical drug companies, utilizing the 505(b)(2) pathway;

and

● patent rights, know-how, exclusive API and manufacturing relationships.

Sales and Marketing

We currently commercialize Biorphen with the support of a co-promotion agreement with Xellia Pharmaceuticals. We intend to commercialize most
of our products through our internal sales and marketing infrastructure. However, in certain scenarios we may conclude that it is financially or strategically
beneficial to out-license, sell, or partner with a third party for commercialization of a product. For example, we sold our EM-100 product candidate to Bausch
Health, who has an established presence in the over-the-counter ophthalmic channel, in exchange for milestone payments and future royalty payments based
on Bausch’s sales of the product.

Our products primarily fall into two categories for commercialization: Hospital injectables and retail prescription products.

Hospital  injectables  products  are  primarily  marketed  to  hospitals  and  surgical  centers  and  may  be  purchased  by  customers  through  wholesalers
and/or  arrangements  with  Group  Purchasing  Organizations  (GPOs).  Our  first  product  launch  in  this  category  was  Biorphen  in  December  2019,  and  our
additional hospital injectable products include DS-300, ET-203, and DS-100.

In January 2020 we signed a co-promotion agreement with Xellia for the promotion of Biorphen. Under terms of the agreement, Xellia’s US-based
hospital sales force will promote Biorphen in certain customer channels in collaboration with Eton, in exchange for a commission based on net sales realized
at certain customer accounts. The product will continue to be sold under Eton’s brand name, and Eton has the right to continue promoting the product to all
customer  accounts.  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.

Our retail prescription products will be promoted to prescribing physicians, primarily neurologists and endocrinologists. We intend to distribute the

products through a network of retail and specialty pharmacies. Our products in this category include ET-105, ET-104, ET-103 and ET-101.

Research and Development

We  currently  have  ten  employees  that  support  research  and  development  and  have  a  laboratory  facility  that  supports  product  development  and
testing. 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  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.

Licensing Arrangements

Certain products in our portfolio were acquired externally through the licensing or acquisition of existing development products including:

Biorphen. We acquired the exclusive license to market Biorphen in the United States pursuant to an Exclusive License and Supply Agreement dated
February  8,  2019  between  us  and  Sintetica.  Pursuant  to  the  terms  of  the  agreement,  we  will  be  responsible  for  marketing  activities  and  Sintetica  will  be
responsible for development, manufacturing, and regulatory activities related to obtaining regulatory approval. We paid Sintetica a licensing payment of $2
million upon execution of the agreement and paid an additional $750,000 upon commercial launch of the product. Sintetica supplies product to us at its direct
costs. We retain 5% of net sales as a marketing fee. Sintetica receives the first $500,000 of product profits, and all additional profit will be split 50% to us and
50% to Sintetica. The agreement has a 10-year term from first commercial sale of product.

ET-105.  On  June  12,  2019,  we  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  ET-105.  Pursuant  to  the  terms  of  the  ET-105  License  Agreement,  we  will  be
responsible for marketing activities and Aucta will be responsible for development, manufacturing, and regulatory activities related to obtaining regulatory
approval.  We  paid  Aucta  a  licensing  payment  of  $2,000,000  in  August  2019  upon  receiving  an  acceptance  for  review  letter  from  the  FDA  and  will  pay
$2,000,000 upon FDA approval and the commencement of commercial sales of the product and another $1,000,000 upon issuance of an Orange-book listed
patent. Aucta will receive a low double-digit royalty on net sales and will be entitled to receive additional milestone payments of up to $18,000,000 in total
based on commercial success of the product, including: $1,000,000 when net sales exceed $10 million in a calendar year; $2,000,000 when net sales exceed
$20 million in a calendar year; $5,000,000 when net sales exceed $50 million in a calendar year; and $10,000,000 when net sales exceed $100 million in a
calendar year.

EM-100.  We  acquired  the  exclusive  rights  to  develop,  manufacture  and  sell  the  EM-100  product  in  the  United  States  pursuant  to  a  Sales  and
Marketing  Agreement  dated  August  11,  2017  between  us  and  Eyemax  LLC  (“Eyemax”),  an  entity  affiliated  with  our  Chief  Executive  Officer  (the  “Sales
Agreement”). On February 18, 2019, we entered into an Amended and Restated Agreement (the “Amended Agreement”) with Eyemax amending the Sales
Agreement. Pursuant to the Amended Agreement, Eyemax sold us all of its right, title and interest in EM-100, including any such product that incorporates or
utilizes Eyemax’s intellectual property rights. Pursuant to the Amended Agreement, we remain obligated to pay Eyemax two milestones: (i) one milestone
payment for $250,000 upon regulatory approval in the territory by the FDA of the first single agent product and (ii) one milestone payment for $500,000
following the first commercial sale of the first single agent product in the territory. Following payment of the milestones, we are entitled to retain all of the
non-royalty transaction revenues and royalties up to $2,000,000 (the “Recovery Amount”). After we have retained the full Recovery Amount, we are entitled
to retain half of all royalty and non-royalty transaction revenue.

On February 18, 2019, we entered into an Asset Purchase Agreement with Bausch. Pursuant to the Asset Purchase Agreement, we sold all of our
right, title and interest in EM-100 in the United States, including any such product that incorporates or utilizes our intellectual property rights with respect to
EM-100. Pursuant to the Asset Purchase Agreement, Bausch paid us an upfront payment of $500,000 and Bausch is required to pay us a milestone payment
of $1,500,000 upon the first sale of the product. Bausch is required to pay us a royalty in the low-double digit percentage range on net sales for a period of 10
years from the date of the first commercial sale of the first single agent EM-100 product in the United States. In the event that any product with the same sole
active pharmaceutical ingredient (“API”) as EM-100 is launched in the United States by any person other than Bausch (or its affiliates) during the term of
Bausch’s royalty commitment, then the royalty rate will be reduced to a lower specified percentage. In the event that EM-100’s market share in the territory
falls below a certain percentage of the target market during the term of Bausch’s royalty commitment, then the royalty rate will be further reduced to a lower
specified percentage.

ET-103. We  acquired  the  exclusive  license  to  develop,  manufacture  and  sell  ET-103  in  the  United  States  pursuant  to  an  Exclusive  License  and
Supply  Agreement  dated  August  3,  2018  between  us  and  Liqmeds  Worldwide  Limited,  an  unaffiliated  entity.  Pursuant  to  the  agreement,  we  will  be
responsible for, and shall own, all regulatory filings and approvals at our expense, provided that we shall have the right to recoup 35% of any regulatory filing
fees  from  the  initial  profits  from  the  sale  of  ET-103  and,  provided  further,  the  licensor  shall  be  responsible  for  any  bioequivalence  study  and  shall  be
responsible for 60% of the costs of such study. An affiliate of the licensor shall manufacture the ET-103 and sell it to us at its cost. We paid the licensor
$350,000 upon execution of the agreement and will pay the licensor $1,500,000 upon the FDA’s acceptance of an NDA for review, $1,000,000 upon FDA
approval,  $1,500,000  upon  issuance  of  patent  covering  ET-103  listed  in  the  FDA’s  Orange  Book  and  $500,000  in  the  event  of  product  sales  in  excess  of
$10,000,000 in any calendar year. In addition, we are required to pay the licensor 35% of the net profit from product sales. The license agreement is for an
initial term of ten years from the date of the first commercial sale of the product, subject to two-year renewals unless either party elects to terminate no less
than 12 months prior to the then current term.

DS-300.  We  acquired  the  exclusive  rights  to  develop,  manufacture  and  sell  the  DS-300  product  in  the  United  States  pursuant  to  a  Sales  and
Marketing Agreement dated November 17, 2017, as amended on August 29, 2018, with an unaffiliated third party. Pursuant to the agreement, the licensor is
responsible for obtaining FDA approval, at its expense, and we are responsible for commercializing the product in the United States, at our expense. The
agreement has a term of ten years from the date of the first commercial sale of the DS-300, subject to one five-year extension at our option. The licensor may
terminate the agreement if we choose not to launch the DS-300, for commercial reasons only, within three months after FDA approval or if during the first
calendar year following the first commercial sale of the DS-300 net sales of the product do not exceed $1 million. The agreement also contains customary
representations, warranties, covenants and indemnities by the parties. In February 2020, we executed an amendment to the Sales and Marketing Agreement.
Under the revised terms, Eton will be responsible for Paragraph IV related litigation and will be entitled to 62.5% of product profit, generally defined as gross
profit less certain fees and costs incurred by us.

DS-100.  We  acquired  the  exclusive  rights  to  develop,  manufacture  and  sell  the  DS-100  product  in  the  United  States  pursuant  to  an  Exclusive
Development and Supply Agreement dated July 9, 2017 between us and Andersen Pharma, LLC, an entity affiliated with our Chief Executive Officer. We
also hold an option to purchase the DS-100 product and all related intellectual property and government approvals. Pursuant to the agreement, the licensor is
responsible  for  obtaining  FDA  approval  at  its  expense  and  manufacturing  the  product  for  sale  to  us  at  its  cost,  however  we  are  responsible  for  the
advancement  of  the  FDA  submission  fees,  which  we  have  the  right  to  recoup  from  the  initial  profits  from  product  sales  prior  to  any  profit  split.  We  are
responsible for commercializing the product in the United States at our expense. We paid the licensor $750,000 upon execution of the agreement and will pay
the  licensor  $750,000  upon  successful  completion  of  a  registration  batch  of  product,  $750,000  upon  submission  of  an  NDA  and  $750,000  upon  FDA
approval. We will also pay the licensor 50% of the net profit from the sale of the product. The license agreement is for an initial term of five years from the
first  commercial  sale  of  the  product,  subject  to  successive  two-year  renewals  unless  either  party  elects  to  terminate  the  agreement.  The  agreement  also
contains customary representations, warranties, covenants and indemnities by the parties.

ET-104.  We  acquired  the  exclusive  license  to  sell  ET-104  in  the  United  States  pursuant  to  an  Exclusive  License  and  Supply  Agreement  dated
January 23, 2019 between us and Liqmeds Worldwide Limited. Pursuant to the agreement, we will be responsible for regulatory and marketing activities. We
paid the licensor $350,000 upon execution of the agreement and will pay the licensor additional milestones of up to $2.15 million based on the achievement
of certain development and commercial milestones. In addition, we are required to pay the licensor 35% of the net profit from product sales. The agreement is
for an initial term of 10 years from the date of the first commercial sale of the product, and we will retain sole ownership after expiration of the agreement.

ET-203. We  acquired  the  exclusive  license  to  market  ET-203  pursuant  to  an  Exclusive  License  and  Supply  Agreement  dated  February  8,  2019
between  us  and  Sintetica.  Pursuant  to  the  terms  of  the  agreement,  we  will  be  responsible  for  marketing  activities  and  Sintetica  will  be  responsible  for
development,  manufacturing,  and  regulatory  activities  related  to  obtaining  regulatory  approval.  We  paid  Sintetica  a  licensing  payment  of  $1  million  upon
execution of the agreement and will pay an additional $750,000 upon FDA approval of the product candidate. Upon approval, Sintetica will supply ET-203 to
us at its direct costs. We will retain 5% of net sales as a marketing fee. Sintetica will be entitled to receive the first $500,000 of product profits. All additional
profit will be split 50% to us and 50% to Sintetica. The agreement has a 10-year term from first commercial sale of product. In January of 2020, we amended
the agreement as a result of the product’s initial new drug application receiving a refuse to file letter from the FDA, Eton was returned the initial $1 million
licensing payment that we paid to Sintetica upon execution of the original agreement. If Sintetica resubmits the product NDA and the FDA accepts it for
review, Eton will repay the $1 million licensing fee.

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.

Our  development  partner  has  filed  a  patent  application  for  ET-104.  We  intend  to  seek  patent  protection  on  our  internally  developed  products  as

circumstances warrant.

Our development partner for ET-105 was granted a patent by the United States Patent and Trademark Office for the product’s unique formulation.

We expect the patent to be Orange Book listed after product approval.

We have applied for trademark registration of the marks “Eton” and “Eton Pharmaceuticals” with the U.S. Patent and Trademark Office.

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  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 usually 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 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 complete response letter 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  complete  response  letter
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.

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.

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,  President  Trump  has  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 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.” On January 22, 2018, 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 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”. 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 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.

13

 
 
 
 
 
 
 
 
 
 
 
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 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 the Trump administration have
each indicated that it will continue to seek new legislative and/or administrative measures to control drug costs.

Moreover,  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.
Additionally,  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.

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.

We have a history of significant operating losses and anticipate continued operating losses for the foreseeable future.

To date, we are not profitable and have incurred losses since our inception in April 2017. For the years ended December 31, 2019 and 2018, we
incurred a net loss of $18.3 million and $12.7 million, respectively, and our operations used $18.0 million and $8.1 million of cash and cash equivalents,
respectively. We have realized limited revenues from two products and expect to incur significant development expenses for our product candidates in the
United States and elsewhere. We may never be able to obtain regulatory approval for the marketing of our additional product candidates for any indication in
the United States or internationally and there can be no assurance that we will generate significant revenues or ever achieve profitability.

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

As  a  result,  we  expect  to  incur  substantial  losses  for  the  foreseeable  future.  We  are  uncertain  when  or  if  we  will  be  able  to  achieve  or  sustain
profitability.  If  we  achieve  profitability  in  the  future,  we  may  not  be  able  to  sustain  profitability  in  subsequent  periods.  Failure  to  become  and  remain
profitable may impair our ability to sustain operations and adversely affect our business and our ability to raise capital. If we are unable to generate positive
cash flow within a reasonable period of time, we may be unable to further pursue our business plan or continue operations.

We could need additional financing to execute our business plan and fund operations, which additional financing may not be available on reasonable
terms or at all.

As of December 31, 2019, we had total assets of $17.1 million and working capital of $13.0 million. We received $22.0 million in net proceeds from
our initial public offering (“IPO”) in November 2018. In November 2019, we entered into a $10.0 million debt facility with SWK Holdings Corporation, and
we received $5.0 million at closing with the option to drawdown additional capital if certain product candidates are approved. We could require additional
funding  at  a  future  point  in  time.  In  the  event  we  require  additional  capital,  we  will  endeavor  to  seek  additional  funds  through  various  financing  sources,
including the sale of our equity and debt securities, licensing fees for our technology and joint ventures with industry partners. In addition, we will consider
alternatives to our current business plan that may enable to us to achieve additional revenue producing operations and meaningful commercial success with a
smaller amount of capital. However, there can be no guarantees that such funds will be available on commercially reasonable terms, if at all. If such financing
is not available on satisfactory terms, we may be unable to further pursue our business plan and we may be unable to continue operations.

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

As our development and commercialization plans and strategies develop, we will 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 we are not successful in attracting and retaining highly qualified personnel, we may not be able to successfully implement our business strategy. In
addition, the loss of the services of our senior management would adversely impact our business prospects.

Our management team has expertise in many different aspects of drug development and commercialization. However, our ability to compete in the
highly competitive pharmaceuticals industry depends in large part upon our ability to attract and retain highly qualified managerial, scientific and medical
personnel. We will need to hire additional personnel as we further develop our product candidates. Competition for skilled personnel in our market is intense
and competition for experienced scientists may limit our ability to hire and retain highly qualified personnel on acceptable terms. Despite our efforts to retain
valuable employees, members of our management and scientific teams may terminate their employment with us on short notice. The loss of the services of
any of our executive officers or other key employees, or our inability to hire targeted executives, could potentially harm our business, operating results or
financial condition. In particular, we believe that the loss of the services of our chief executive officer would have a material adverse effect on our business.

Other pharmaceutical companies with which we compete for qualified personnel have greater financial and other resources, different risk profiles,
and a longer history in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these
characteristics may be more appealing to high-quality candidates than what we have to offer. If we are unable to continue to attract and retain high-quality
personnel, the rate and success at which we can develop and commercialize product candidates would be limited.

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  Biorphen  product  and  clinical  testing  of  our  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
Biorphen 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 Biorphen or any of our product candidates or any future products that we may develop;

● injury to our reputation;

16

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● 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 Biorphen 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  Biorphen  or  additional  products  we  develop.  Although  we  will  endeavor  to  obtain  and  maintain  such  insurance  in
coverage  amounts  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  Biorphen  product  on  our  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
Biorphen product on our 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.

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.

Our  Chief  Executive  Officer,  Sean  Brynjelsen,  has  a  material  ownership  interest  in  several  companies  from  which  we  have  licensed  or  acquired
product  development  and  marketing  rights.  See,  “Notes  to  Financial  Statements  -  Related  Party  Transactions.”  We  are  required  to  pay  these  entities  a
combination of licensing fees, milestone payments and royalty payments. The transactional agreements also subject us to a loss of our rights to the product
candidates  in  the  event  we  breach  any  of  our  representations,  warranties  or  covenants  included  in  the  agreements.  While  we  believe  the  terms  of  the
transactional  agreements,  including  the  licensing  fees,  milestone  payments  and  royalty  payments,  approximate  the  terms  and  payments  we  could  have
obtained in an arms’ length transaction with an unaffiliated party, these arrangements may present Mr. Brynjelsen with a conflict of interest in the event of
dispute between the parties. Although we believe we have mechanisms in place to protect the interests of our stockholders, including a board of directors, a
majority of which are independent and have no interest in these related parties, there can be no assurance that a conflict of interest will not arise or that any
such conflict will not adversely impact the interests of our stockholders.

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

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

We have various product candidates are in the early stages of clinical development, and we do not generate revenues from any FDA approved drug
products other than Biorphen. An abbreviated new drug application (“ANDA”) was submitted for our EM-100 product candidate and our DS-300 product. In
addition,  an  NDA  was  submitted  for  ET-105  in  May  2019.  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.

18

 
 
 
 
 
 
 
 
 
 
 
 
 
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.

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).

21

 
 
 
 
 
 
 
 
 
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.

22

 
 
 
 
 
 
 
 
 
 
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 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.

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.

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.

24

 
 
 
 
 
 
 
 
 
 
 
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.

25

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.

We currently have a limited sales and marketing organization and one partner for co-promotion of our Biorphen product. If we are unable to secure a
sales  and  marketing  partner  for  potential  future  products  or  establish  satisfactory  sales  and  marketing  capabilities,  we  may  not  successfully
commercialize our product candidates.

We  have  limited  sales  and  marketing  personnel.  In  order  to  commercialize  products  that  are  approved  for  commercial  sales,  we  must  either
collaborate  with  third  parties  that  have  such  commercial  infrastructure  or  develop  our  own  sales  and  marketing  infrastructure.  If  we  are  not  successful
entering into appropriate collaboration arrangements or recruiting sufficient sales and marketing personnel or in building a sales and marketing infrastructure,
we  will  have  difficulty  successfully  commercializing  our  product  candidates,  which  would  adversely  affect  our  business,  operating  results  and  financial
condition.

We  may  not  be  able  to  enter  into  additional  collaboration  agreements  on  terms  acceptable  to  us  or  at  all.  In  addition,  even  if  we  enter  into  such
relationships, we may have limited or no control over the sales, marketing and distribution activities of these third parties. Our future revenues may depend
heavily on the success of the efforts of these third parties. If we elect to establish a sales and marketing infrastructure, we may not realize a positive return on
this investment. In addition, we will have to compete with established and well-funded pharmaceutical and biotechnology companies to recruit, hire, train and
retain  sales  and  marketing  personnel.  Factors  that  may  inhibit  our  efforts  to  commercialize  our  product  candidates  without  strategic  partners  or  licensees
include:

●

●

●

●

our inability to recruit and retain adequate numbers of effective sales and marketing personnel;

the inability of sales personnel to obtain access to or educate an adequate number of physicians as to the benefits of any our product candidates;

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

unforeseen costs and expenses associated with creating an independent sales and marketing organization.

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,  President  Trump  has  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, 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.

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  the  Trump
administration have each indicated that it 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.

27

 
 
 
 
 
 
 
 
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.

Our future profitability may depend, in part, on our ability to commercialize our product candidates in international markets for which we intend to
rely on collaborations with third parties. If we commercialize any of our product candidates in international markets, we would be subject to additional risks
and uncertainties, including:

●

●

●

●

●

●

●

●

●

●

●

●

our customers’ ability to obtain reimbursement for our product candidates in international markets;

our inability to directly control commercial activities because we are relying on third parties;

the burden of complying with complex and changing international regulatory, tax, accounting and legal requirements;

different medical practices and customs in foreign countries affecting acceptance in the marketplace;

differing payor reimbursement regimes, governmental payors or patient self-pay systems and price controls

import or export licensing requirements;

longer accounts receivable collection times;

longer lead times for shipping;

language barriers for technical training;

reduced protection of intellectual property rights in some foreign countries;

foreign currency exchange rate fluctuations; and

the interpretation of contractual provisions governed by foreign laws in the event of a contract dispute.

International sales of our product candidates could also be adversely affected by the imposition of governmental controls, political and economic

instability, trade restrictions and changes in tariffs, any of which may adversely affect our results of operations.

If we market Biorphen or any of our 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 will be completely dependent on third parties to manufacture our 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.

29

 
 
 
 
 
 
 
 
 
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.

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. 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. 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 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 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

 
 
 
 
 
 
 
 
 
 
 
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.

Our  Chief  Executive  Officer,  Sean  Brynjelsen,  has  a  material  ownership  interest  in  several  companies  from  which  we  have  licensed  or  acquired
product development and marketing rights. These include a 27% stake in Andersen Pharma, LLC (license for DS-100), 33% stake in Eyemax, LLC (license
for  EM-100)  and  50%  stake  in  Selenix,  LLC  (license  for  DS-200).  We  are  required  to  pay  these  parties  licensing  fees,  milestone  payments  and  royalty
payments.  We  believe  the  terms  of  the  transactional  agreements,  including  the  licensing  fees,  milestone  payments  and  royalty  payments,  approximate  the
terms and payments we could have obtained in an arms’ length transaction with an unaffiliated party. Nonetheless, a stockholder may seek to challenge these
agreements on grounds that they are not in the best interest of our company and our board breached its fiduciary duty by approving such agreements.

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 have not conducted clinical trials for any of our product candidates, other than a bioequivalence trial for one product candidate, 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.

33

 
 
 
 
 
 
 
 
 
To date, we have not conducted any clinical trials other than a Phase 3 bioequivalence trial for our EM-100 product candidate. Our clinical trials may
not  be  successful,  and  even  if  they  are,  the  FDA  may  not  approve  our  NDA  for  products  that  are  successful  in  the  trial,  may  not  agree  that  the  benefits
outweigh its risks, or may raise new concerns regarding our clinical trial designs. The Phase 3 trial process is often long, complex, costly and uncertain, and
delays or failure are common.

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.

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.

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

Our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets. A severe or
prolonged  global  economic  downturn  could  result  in  a  variety  of  risks  to  our  business,  including  our  ability  to  raise  additional  capital  when  needed  on
acceptable terms, if at all. This is particularly true in Europe, which is undergoing a continued severe economic crisis. A weak or declining economy could
also strain our suppliers, possibly resulting in supply disruption. Any of the foregoing could harm our business and we cannot anticipate all of the ways in
which the current economic climate and financial market conditions could adversely impact our business.

The  United  Kingdom’s  referendum  to  leave  the  European  Union  or  “Brexit,”  has  and  may  continue  to  cause  disruptions  to  capital  and  currency
markets worldwide. The full impact of the Brexit decision, however, remains uncertain. A process of negotiation will determine the future terms of the United
Kingdom’s relationship with the European Union. During this period of negotiation, our results of operations and access to capital may be negatively affected
by interest rate, exchange rate and other market and economic volatility, as well as regulatory and political uncertainty. Brexit may also have a detrimental
effect on our suppliers and manufacturers, which would, in turn, adversely affect our financial condition.

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 is 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. Our development
partner  has  filed  a  patent  application  for  ET-104.  In  addition,  our  development  partner  for  ET-105  was  granted  a  patent  by  the  United  States  Patent  and
Trademark office. 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.

35

 
 
 
 
 
 
 
 
 
 
 
 
 
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.

36

 
 
 
 
 
 
 
 
 
 
 
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.

37

 
 
 
 
 
 
 
 
 
 
 
 
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 filed a Form S-3 registration statement (“Shelf Registration”) with the SEC that became effective in December 2019 which will allow 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.  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.

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;

39

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● 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.

We will continue to incur significant costs as a result of becoming a public company that reports to the Securities and Exchange Commission (the “SEC”)
and our management will be required to devote substantial time to meet compliance obligations.

As  a  newly  public  company  reporting  to  the  SEC,  we  incur  significant  legal,  accounting  and  other  expenses  that  we  did  not  incur  as  a  private
company.  We  are  subject  to  reporting  requirements  of  the  Securities  Exchange  Act  of  1934  (the  “Exchange  Act”),  and  the  reporting  and  governance
provisions of the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Protection Act, as well as rules subsequently implemented by the SEC, that
impose significant requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls and
changes in corporate governance practices. There are significant corporate governance and reporting provisions in these laws that will increase our legal and
financial compliance costs, make some activities more difficult, time-consuming or costly and may also place undue strain on our personnel, systems and
resources. Our management and other personnel will need to devote a substantial amount of time to these regulations. In addition, we expect these rules and
regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced
policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and
retain qualified people to serve on our board of directors, our board committees or as executive officers.

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  currently  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 February 28, 2020, we had 17,882,486 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.

We have broad discretion over the use of proceeds from our IPO, a recent debt financing and potential future securities offerings.

Our management has considerable discretion in the application of the net proceeds from our IPO and debt financing in November 2019. We expect to
use the proceeds from our IPO and the debt financing to fund clinical trials, product licensing opportunities and product development; to fund FDA filing
fees; to fund laboratory expansion and for other general corporate purposes, including general and administrative expenses and working capital. However, our
needs  may  change  as  our  business  and  industry  evolve  and,  as  a  result,  the  proceeds  from  our  IPO  and  the  debt  financing  may  be  used  in  a  manner
substantially different from our current expectations. We may use the net proceeds for purposes that do not yield a significant return or any return at all for our
stockholders. In addition, pending their use, we may invest the net proceeds from our IPO and debt financing in a manner that does not produce income or
that loses value. The failure by our management to apply these funds effectively could result in financial losses that could harm our business, cause the price
of our common stock to decline and delay the development of our product candidates.

In addition, our management will have broad discretion to use the net proceeds from any offerings under the Shelf Registration, and you will be
relying on the judgment of our management regarding the application of these proceeds. Except as described in any future prospectus supplement, the net
proceeds  received  by  us  from  our  sale  of  these  securities  will  be  added  to  our  general  funds  and  will  be  used  for  our  general  corporate  purposes.  Our
management might not apply the net proceeds from the offering of our securities in ways that increase the value of your investment and might not be able to
yield a significant return, if any, on any investment of such net proceeds. You may not have the opportunity to influence our decisions on how to use such
proceeds.

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.

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.

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 11.4% of our common stock. Additionally, Harrow Health, Inc. (“Harrow”), our
former  parent  company,  holds  approximately  19.6%  of  our  outstanding  common  stock.  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.

We may be constrained by our obligations under our Credit Agreement to operate our business to its full potential.

On  November  13,  2019,  we  entered  into  a  $10  million  credit  facility  with  SWK  Holdings  Corporation  (the  “Credit  Agreement”).  The  Credit
Agreement contains customary representations and warranties and customary affirmative and negative covenants, including, among other things, restrictions
on indebtedness, liens, investments, mergers, dispositions, prepayment of other indebtedness and dividends and other distributions. Under the terms of the
Credit Agreement, we are required to comply with (a) a maximum senior secured net leverage ratio, (b) a maximum total net leverage ratio and a minimum
fixed charge coverage ratio. These terms may restrict our ability to operate our business in the manner we deem most effective or desirable, and may restrict
our ability to fund our operations through new public offerings of our common stock or strengthen our candidate development pipeline through acquisitions
or licenses which cause us to exceed our maximum senior secured net leverage ratio.

Failure  to  comply  with  the  representations  and  warranties  or  affirmative  and  negative  covenants  could  constitute  an  event  of  default  which,  if
continued beyond the cure period, would allow the Agent (as defined in the Credit Agreement), at the request of or with the consent of the lenders holding a
majority of the loans and commitments under the facility, to terminate the commitments of the lenders to make further loans and declare all the obligations of
the loan parties under the Credit Agreement to be immediately due and payable, either of which could harm our business.

Market Information

PART II

Our common stock is listed on the Nasdaq Global Market under the symbol “ETON.” The closing price of our common stock on the Nasdaq Global

Market on December 31, 2019, the last trading date in 2019, was $7.20 per share.

Record Holders

As of February 28, 2020, we had 16 holders of record of our common stock. The actual number of stockholders is greater than this number of record
holders and includes stockholders who are beneficial owners but whose shares are held in street name by brokers and other nominees. This number of holders
of record also does not include stockholders whose shares may be held in trust by other entities. The closing price per share of our common stock on February
28, 2020 was $5.40

Dividends

We have never declared or paid a cash dividend on our common stock. We currently intend to retain any future earnings and do not expect to pay any
dividends  in  the  foreseeable  future.  Any  future  determinations  to  pay  cash  dividends  will  be  made  at  the  discretion  of  our  board  of  directors,  subject  to
applicable laws, and will depend on a number of factors, including our financial condition, results of operations, capital requirements, contractual restrictions,
general business conditions, and any other factors that our board of directors may deem relevant.

Recent Sales of Unregistered Securities

In November 2018, we entered into an underwriting agreement, relating to the public offering of 4,140,000 shares of common stock at a price to the
public  of  $6.00  per  share,  less  underwriting  discounts  and  commissions.  In  November  2018,  in  connection  with  the  underwriting  agreement,  we  issued
warrants  exercisable  for  414,000  shares  of  common  stock  at  an  exercise  price  of  $7.50  per  share  to  National  Securities  Corporation,  a  wholly  owned
subsidiary of National Holdings, Inc.

The issuance of these warrants was made in reliance on the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as

amended (the “Securities Act”) and/or Regulation D promulgated thereunder as private transactions not involving a public offering of securities.

In November 2019, in connection with the Credit Agreement, we issued a warrant exercisable for shares of common stock equal to six percent (6%)
of the principal amount of draws upon exercise of each tranche under the Credit Agreement divided by the average trading price of common stock for the ten
trading days immediately preceding such exercise.

The  issuance  of  this  warrant  was  made  in  reliance  on  the  exemption  from  registration  contained  in  Section  4(a)(2)  of  the  Securities Act  and/or

Regulation as private transactions not involving a public offering of securities.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You  should  read  the  following  discussion  and  analysis  together  with  our  financial  statements  and  the  related  notes  thereto  included  in  “Item  8.
Financial  Statements  and  Supplementary  Data”  in  this  Annual  Report  on  Form  10-K.  The  following  discussion  contains  forward-looking  statements  that
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  were  formed  in  April  2017  as  a  specialty  pharmaceutical  company  focused  on  developing  and  commercializing  innovative  pharmaceutical
products  utilizing  the  FDA’s  505(b)(2)  regulatory  pathway.  Our  business  model  is  to  develop  proprietary  innovative  products  that  fulfill  an  unmet  patient
need. Since our formation, we have focused our efforts on the development of our initial product candidates, engaging in preliminary discussions with the
FDA concerning the regulatory pathway for certain additional product candidates, registration filings of our initial product candidates and the licensing of
late-stage product candidates.

In December 2019 we launched our Biorphen product and we have established a diversified pipeline of other product candidates in various stages of
development, four of which have been submitted to the FDA and are under review. We intend to focus on product candidates that are liquid in formulation,
including injectables, oral liquids and ophthalmics, and qualify under the FDA’s 505(b)(2) regulatory pathway.

Our corporate strategy is to pursue what we perceive 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 us to bring the product to
patients. We intend to pursue product candidates that require a single small Phase 3 trial, a bioequivalence trial, or literature-based filings. Prior to initiating
significant development activities on a product candidate, we typically meet with the FDA to establish a defined clinical and regulatory path to approval.

We believe our product candidates can address situations where patient needs are not being met by current FDA-approved pharmaceutical products.
This may include products that are being supplied on an unapproved basis, products that are currently being compounded, and products that are approved and
widely used internationally but not approved in the United States.

Results of Operations

To date we have realized only limited revenues from a licensing arrangement on our EM-100 product and the launch of our Biorphen product. We

anticipate successfully completing development of additional product candidates in 2020 and beyond and growing our business.

Year Ended December 31, 2019 Compared to Year Ended December 31, 2018

For  the  years  ended  December  31,  2019  and  2018,  we  generated  $1.0  and  $0  in  revenue,  respectively.  The  revenue  realized  in  2019  was  from  a
licensing arrangement for our EM-100 product which is pending additional FDA review and the launch of our Biorphen product in December 2019. For the
years 2019 and 2018, we incurred $11.6 million and $5.6 million of research and development (“R&D”) expenses, respectively, and $7.6 million and $4.7
million of general and administrative (“G&A”) expenses, respectively. The comparative period detail of our R&D expense is listed in the table below. The
$2.9 million increase in G&A expenses was primarily due to additional expenses related to becoming a public company, sales and marketing for the launch of
our Biorphen product, and the impact of personnel additions in the second half of 2018 and first half of 2019. This was partially offset by lower stock-based
consulting expenses. In addition, the change in the fair value of our warrant liability reflected in other expense decreased by $2.6 million as this mark–to–
market accounting treatment was terminated in conjunction with our November 2018 IPO. We incurred a net loss of $18.3 million and $12.7 million for the
years ended December 31, 2019 and 2018, respectively.

General and Administrative Expenses

G&A expenses consist primarily of employee compensation expenses, stock-based consulting service fees, sales and marketing expenses, business

insurance, legal and professional fees and travel expenses.

capital equipment additions were added in late 2018. We do not track internal costs by product for our employees and laboratory expenses and they are listed
as indirect expenses in the table below (amounts are in thousands).

Year Ended December 31, 2018 Compared to Period Ended December 31, 2017

For the periods ended December 31, 2018 and 2017, we incurred $5.6 million and $3.9 million of research and development (“R&D”) expenses,
respectively,  and  $4.7  million  and  $3.2  million  of  general  and  administrative  (“G&A”)  expenses,  respectively. The  comparative  period  detail  of  our  R&D
expense is listed in the table below. The $1.5 million increase in G&A expenses was primarily due to the partial year start-up in late April 2017 as compared
to a full year of operations in 2018 combined with personnel additions in the second half of 2018. Our compensation-related costs increased by $1.1 million
plus costs for our board of directors increased by $0.4 million. In addition, the fair value of our warrant liability reflected in other expense increased by $2.5
million as a result of the increase in our stock price up to the date of our IPO. We incurred a net loss of $12.7 million and $7.2 million for the periods ended
December 31, 2018 and 2017, respectively.

General and Administrative Expenses

G&A  expenses  consist  primarily  of  employee  compensation  expenses,  stock-based  consulting  service  fees,  legal  and  professional  fees  and  travel
expenses. We anticipate that our G&A expenses will significantly increase to support our business growth and the additional costs associated with being a
public company.

Research and Development Expenses

Set  forth  below  is  our  R&D  spending  for  our  current  product  candidates.  We  currently  have  nine  employees  that  support  our  overall  product
development and we also have facility and operating costs for a laboratory that will support product development. We do not track internal costs by product
for our employees and laboratory expenses and they are listed as indirect expenses in the table below (amounts are in thousands).

Liquidity and Capital Resources

As of December 31, 2019, we had total assets of $17.1 million and working capital of $13.0 million. We had previously capitalized our operations
primarily from the June 2017 private placement of approximately $20.1 million of Series A preferred stock, par value $0.001 (the “Series A Preferred”). Our
Series  A  Preferred  accumulated  dividends  at  the  rate  of  6%  per  annum  and  those  shares  of  stock  plus  all  accrued  but  unpaid  dividends  automatically
converted into shares of our common stock concurrent with our IPO in November 2018 at the conversion price of 50% of the IPO price. The IPO provided us
with net proceeds of $22.0 million and we also entered into a Credit Agreement with SWK Holdings in November 2019 which provides for up to $10 million
in additional borrowing, $5.0 million of which was received at closing. We believe that our existing funding and the revenue from our Biorphen product and
potential  milestones  and  royalty  payments  from  EM-100  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 increase in cash used in operating activities is primarily a result of higher operating losses due to our business expansion including additional
personnel and increased product candidate development activity. Investing activities consist primarily of licensing fees for Biorphen and capital expenditures
for setting up our laboratory facility and our headquarters office. The financing activity primarily consists of the Series A Preferred private placement funding
in June 2017, the November 2018 IPO and the November 2019 Credit Agreement with 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 condensed 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

We account for contracts with its 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.

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  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 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. To date, we have not recognized any royalty revenue resulting from any of our licensing arrangements.

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.

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 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.

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. 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.

Upon  recognition  of  revenue  from  product  sales  of  Biorphen,  the  estimated  amounts  of  credit  for  product  returns,  chargebacks,  distribution  fees,
prompt payment discounts, 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.

50

 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 the Financial Accounting Standards Board (the “FASB”) Accounting Standards
Codification (“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 for employees and directors and record expense over the related service periods, which are generally the
vesting period of the equity awards. Awards for consultants are accounted for under ASC 505-50 - Equity Based Payments to Non-Employees. Compensation
expense  is  recognized  over  the  period  during  which  services  are  rendered  by  such  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 employees and directors 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, which management believes 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 “IPO”), 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.

51

 
 
 
 
 
 
 
 
 
 
 
 
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.

We are in the process of evaluating the benefits of relying on other exemptions and reduced reporting requirements under the JOBS Act. 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,  2019,  our  cash  equivalents  and  investments  are  invested  exclusively  in  money  market  funds.  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, 2019 and 2018, the related
statements of operations, redeemable convertible preferred stock and stockholders’ equity (deficit) and cash flows for the years ended December 31, 2019 and
2018, and the period from April 27, 2017 (inception) to December 31, 2017 and the related notes and the financial statement schedule listed in the index at
Item 15 (2) (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, 2019 and 2018, and the results of its operations and its cash flows for each of the years ended December 31,
2019  and  2018  and  the  period  from  April  27,  2017  (inception)  to  December  31,  2017,  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  the  Company’s
financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States)
(“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and
regulations of the Securities and Exchange Commission and the PCAOB.

We  conducted  our  audits  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain
reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to
have,  nor  were  we  engaged  to  perform,  an  audit  of  its  internal  control  over  financial  reporting.  As  part  of  our  audits  we  are  required  to  obtain  an
understanding  of  internal  control  over  financial  reporting  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal
control over financial reporting. Accordingly, we express no such opinion.

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

Eton Pharmaceuticals, Inc.
NOTES TO FINANCIAL STATEMENTS
(in thousands, except share and per share amounts)

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.).

Eton raised $20,055 in start-up capital through the sale of its Series A redeemable convertible preferred stock (“Series A Preferred”) in June 2017
and a separate management team was then established for Eton with its corporate offices located in Deer Park, Illinois. Eton is a specialty pharmaceutical
company focused on developing and commercializing prescription drug products utilizing the U.S. Food and Drug Administration’s (the “FDA”) 505(b)(2)
regulatory  pathway.  The  Company’s  business  model  is  to  develop  proprietary  innovative  product  candidates  that  offer  commercial  and/or  functional
advantages to currently available alternatives.

In  November  2018,  the  Company  completed  an  initial  public  offering  (“IPO”),  selling  4,140,000  shares  of  common  stock  at  an  offering  price  of
$6.00 per share, including the underwriter’s exercise in full of its option to purchase additional shares. The Company received net proceeds of $21,960, after
deducting underwriting discounts and commissions and offering-related expenses (see Note 8).

The Company’s Biorphen® product was approved by the FDA in October 2019 and sales commenced for this product at the end of 2019.

Note 2 — Liquidity Considerations

As of December 31, 2019, the Company had an accumulated deficit of $64,188 and for the year ended December 31, 2019 the Company used net

cash in operating activities of $18,026.

To date, the Company has realized limited revenues from two products, but expects further growth in 2020 and beyond and currently believes its
existing cash and cash equivalents 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, the
useful lives of long-lived assets, the accrual of research and development expenses and the valuation of common stock, stock options, warrants and derivative
instruments. 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.

Note 3 — Summary of Significant Accounting Policies (continued)

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. Cash equivalents consist of an interest-bearing checking account. From time to time, amounts deposited
exceed federally insured limits. The Company believes the associated credit risk to be minimal.

Accounts Receivable

Accounts  receivable  is  recorded  at  the  invoiced  amount  and  is  non-interest  bearing.  Accounts  receivable  is  recorded  net  of  allowances  for  doubtful

accounts, cash discounts for prompt payment, distribution fees, chargebacks and returns and allowances.

Inventory

The Company values its inventory at the lower of cost or net realizable value using the first-in, first-out method of valuation. The Company reviews
its  inventory  for  potential  excess  or  obsolete  issues  and  will  record  a  write-down  if  an  impairment  is  identified.  Inventory  at  December  31,  2019  consists
solely of purchased finished goods.

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.

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  ASC  350-30.  To  date,  a  $750  payment  related  to  the  approval  of  its  Biorphen  product  has  been
capitalized and that cost is being amortized over five years.

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 periods ended December 31, 2019, 2018 and 2017.

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.

Classification and Accretion of Redeemable Convertible Preferred Stock

Prior to the Company’s IPO in November 2018, the Company classified the Series A Preferred outside of stockholders’ equity (deficit) because the
shares  contained  certain  redemption  features  that  were  not  solely  within  the  control  of  the  Company.  The  carrying  value  of  the  Series  A  Preferred  was
accreted to its redemption value from the date of issuance through November 15, 2018, the date of the Company’s IPO. In conjunction with the IPO, the
Series A Preferred, including accrued and unpaid dividends, automatically converted to shares of the Company’s common stock (see Note 7).

Beneficial Conversion Feature

Prior to the IPO in November 2018, the Company classified its Series A Preferred as temporary equity due to a possible cash redemption feature in
the event that an IPO or alternate financing was not completed by December 31, 2018. At the IPO date, the Series A Preferred, and related accrued and unpaid
dividends, automatically converted into shares of the Company’s common stock. The conversion share calculation was based on the $3.00 initial issuance
price for the Series A Preferred plus any accrued but unpaid dividends and converted to common stock using a stated divisor conversion price equal to 50% of
the IPO price to the public, which was $6.00 per share. In accordance with relevant accounting literature, since the stated terms of the conversion option did
not  permit  the  Company  to  compute  the  additional  number  of  shares  that  it  would  need  to  issue  upon  conversion  of  the  Series  A  Preferred  when  the
contingent event occurred, the Company recorded the beneficial conversion amount of $21,747 as a deemed dividend at the date of the IPO in November
2018.

Leases

The Company adopted ASC Topic 842- “Leases”, effective January 1, 2019, using the modified retrospective method. The reported results for fiscal
year 2019 reflect the application of ASC Topic 842, while the reported results for prior fiscal years are not adjusted and continue to be reported under the
prior ASC Topic 840 guidance for leases. Refer to Impact of New Accounting Pronouncements regarding the adoption impact of ASC Topic 842 in the year
ended December 31, 2019.

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, 2019 and 2018.

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 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 invested in money market funds. 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 vendors for its product candidates. In particular, the Company relies, and expects to continue to rely, on a
small number of vendors to manufacture key chemicals and process its product candidates for its development programs. These programs could be adversely
affected by a significant interruption in the manufacturing process.

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, 2019.
The accounts receivable balance at December 31, 2019 and product sales revenue recognized during the year ended December 31, 2019 consist of sales to and
amounts due from AmerisourceBergen Corporation, Cardinal Health Services and McKesson Corporation for sales of its Biorphen product.

Revenue Recognition for Contracts with Customers

The  Company  accounts  for  contracts  with  its  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.

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.

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.

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 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. 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.

Upon  recognition  of  revenue  from  product  sales  of  Biorphen,  the  estimated  amounts  of  credit  for  product  returns,  chargebacks,  distribution  fees,
prompt  payment  discounts,  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.

Cost of Product Sales

Cost  of  product  sales  consists  of  the  profit-sharing  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 provider. The cost of sales
for  profit-sharing  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.

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 2019, 2018 or 2017 as the Company reported a net loss for the periods ended December 31, 2019, 2018 and
2017 and including the effects of common stock equivalents in the diluted earnings per share calculation would have been antidilutive (See Note 11).

Warrant Liability

The Company estimated the fair value of certain warrants at each reporting period using Level 3 inputs. The estimates in valuation models were
based, in part, on subjective assumptions, including but not limited to stock price volatility, the expected life of the warrants, the risk-free interest rate and the
exercise price of the warrants, and could differ materially in the future. Changes in the fair value of the warrant liability during the period were recorded as a
component  of  other  income  (expense)  at  the  end  of  each  reporting  period  for  changes  in  fair  value  until  the  Company’s  IPO  in  November  2018,  which
established a fixed number of shares for these warrants. At the date of the IPO, the warrant liability amount was reclassified as a component of additional
paid-in-capital.

Stock-Based Compensation

The Company accounts for stock-based compensation under the provisions of the Financial Accounting Standards Board (the “FASB”) Accounting
Standards Codification (“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  for  employees  and  directors  and  record  expense  over  the  related  service  periods,  which  are
generally the vesting period of the equity awards. Awards for consultants are accounted for under ASC 505-50 — Equity Based Payments to Non-Employees.
Compensation expense is recognized over the period during which services are rendered by such 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  the
Company’s common stock and updated assumption inputs in the Black-Scholes-Merton option-pricing model (“BSM”).

The Company estimates the fair value of stock-based option awards to its employees and directors using the BSM. The BSM requires the input of
subjective assumptions, including the expected stock price volatility, the calculation of expected term 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, 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.

Note 3 — Summary of Significant Accounting Policies (continued)

Prior to the Company’s IPO, the fair value of the shares of the Company’s common stock underlying its stock-based awards was determined by its
board of directors, with input from management. Because there had been no public market for the Company’s common stock prior to the IPO, the 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 its common stock performed by an unrelated third-party specialist, valuations of comparable companies, sales of its
convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of the capital stock, and general and industry-
specific economic outlook. Following the IPO in November 2018, the Company uses the closing 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, 2019 and 2018, the Company has established a 100% valuation reserve against its deferred tax assets.

The Company accounts for income taxes under the provisions of FASB ASC 740 - Income Taxes. As of December 31, 2019 and 2018, 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, 2019 or 2018, and has not recognized interest and penalties in the statements of operations for the periods ended December 31, 2019, 2018 and
2017. As of December 31, 2019, the Company is subject to taxation in the United States and Illinois. The Company’s tax losses from 2019, 2018 and 2017 are
subject to examination by the federal and state tax authorities due to the carryforward of unutilized net operating losses (“NOLs”).

The  Tax  Cuts  and  Jobs  Act  of  2017  (the  “Tax  Act”)  significantly  revised  U.S.  corporate  income  tax  law  by,  among  other  things,  reducing  the
corporate income tax rate to 21% and implementing a modified territorial tax system. In response to the Tax Act, the SEC issued Staff Accounting Bulletin
(“SAB”) 118 which allows issuers to recognize provisional estimates of the impact of the Tax Act in their financial statements and adjust in the period in
which the estimates become finalized, or in circumstances where estimates cannot be made, to disclose and recognize within a one-year measurement period.

Implementation of the Tax Act resulted in a $733 charge for the revaluation of the Company’s net deferred tax assets offset by a corresponding $733

reduction in the valuation reserve for income taxes during the period ended December 31, 2017.

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, 2019 or 2018.

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.

Note 3 — Summary of Significant Accounting Policies (continued)

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 and long-term
debt obligation. The carrying amounts of these financial instruments, except for the long-term debt obligation, approximate fair value due to the short-term
maturities  of  these  instruments.  Based  on  borrowing  rates  currently  available  to  the  Company,  the  carrying  value  of  the  long-term  debt  obligation
approximates its fair value.

The  fair  values  of  the  Company’s  warrant  liability  at  inception  and  for  subsequent  mark-to-market  fair  value  measurements  were  based  on
management’s valuation model and expectations with respect to the method and timing of settlement. The Company determined that the warrant liability fair
values  were  classified  as  Level  3  measurements  within  the  fair  value  hierarchy.  At  the  date  of  the  Company’s  IPO  in  November  2018,  the  fair  value  was
reclassified to additional paid-in-capital as the final number of shares for the warrants previously reflected as a liability became fixed (see Notes 4 and 9).

Impact of New Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02 (Topic 842) – Leases (“ASC 842”), which requires the lease rights and obligations arising from
lease  contracts,  including  existing  and  new  arrangements  for  substantially  all  leases  with  terms  more  than  twelve  months  to  be  recognized  as  assets  and
liabilities  on  the  balance  sheet.  Recognition,  measurement  and  presentation  of  expenses  depends  upon  classification  as  a  finance  or  operating  lease.  The
Company adopted ASC 842 effective January 1, 2019 utilizing the modified retrospective approach such that prior year financial statements were not recast
under the new standard. The adoption of ASU 2016-02 did not have a material effect on the Company’s financial condition from the recognition of the lease
rights and obligations as assets and liabilities or its results of operations and cash flows. See Note 13 for additional information regarding the new standard
and its impact on the Company’s financial statements.

In  June  2016,  the  FASB  issued  ASU  2016-13,  Financial  Instruments  -  Credit  Losses  (Topic  326),  Measurement  of  Credit  Losses  on  Financial
Instruments. The standard amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit
losses  for  most  financial  assets  and  certain  other  instruments  that  aren’t  measured  at  fair  value  through  net  income.  For  available-for-sale  debt  securities,
entities will be required to recognize an allowance for credit losses rather than a reduction in carrying value of the asset. Entities will no longer be permitted
to consider the length of time that fair value has been less than amortized cost when evaluating when credit losses should be recognized. The Company plans
to  adopt  the  new  guidance  on  January  1,  2020  and  does  not  anticipate  the  adoption  will  have  a  material  impact  on  its  financial  position  or  results  of
operations.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820). The new guidance removes, modifies and adds to certain
disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. The Company plans to adopt the new guidance on January 1,
2020 and does not anticipate the adoption will have a material impact on its financial position or results of operations.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The new guidance removes certain exceptions to
the general principles of ASC 740 in order to simplify the complexities of its application. These changes include eliminations to the exceptions for intraperiod
tax allocation, recognizing deferred tax liabilities related to outside basis differences, and year-to-date losses in interim periods among others. The Company
will adopt ASU 2019-12 in January 2020 and does not anticipate it will have a material impact on its financial position or results of operations.

Note 4 — Fair Value of Financial Assets and Liabilities

Valuation of Warrant Liability

The  Company  previously  accounted  for  a  warrant  to  purchase  shares  of  its  common  stock  that  was  issued  to  the  Company’s  placement  agent  in
connection with the Series A Preferred offering (see Note 9) as a liability. The fair value of the warrant liability was determined based on significant inputs
not observable in the market, which represented a Level 3 measurement within the fair value hierarchy. The Company used the BSM, which incorporates
assumptions and estimates, to value the warrant. Estimates and assumptions impacting the fair value measurement included the fair value per share of the
underlying shares of common stock, the remaining contractual term of the warrant, risk-free interest rate, expected dividend yield and expected volatility of
the price of the underlying common stock. The Company determined the fair value per share of the underlying common stock by taking into consideration the
most  recent  sales  of  its  preferred  stock,  results  obtained  from  third-party  valuations  and  additional  factors  that  were  deemed  relevant.  The  Company
historically  had  been  a  private  company  and  lacked  company-specific  historical  and  implied  volatility  information  of  its  common  stock.  Therefore,  the
Company  estimated  its  expected  stock  volatility  based  on  the  historical  volatility  of  publicly  traded  peer  companies  for  a  term  equal  to  the  remaining
contractual term of the warrant. The risk-free interest rate was determined by reference to the U.S. Treasury yield curve for time periods approximately equal
to the remaining contractual term of the warrant. The Company estimated a 0% expected dividend yield based on the fact that the Company had never paid or
declared dividends and did not intend to do so in the foreseeable future.

In November 2018, in connection with the Company’s IPO, the number of shares issuable upon the exercise of the warrant became fixed (see Note

9). The Company remeasured the estimated fair value on the date of the IPO and reclassified this amount to additional paid-in-capital.

The  following  table  provides  a  roll  forward  of  the  aggregate  fair  values  of  the  Company’s  warrant  liability,  for  which  fair  value  was  determined

using Level 3 inputs:

Note 6 – Long-term Debt

On November 13, 2019, the Company entered into a credit agreement (the “SWK Credit Agreement”) with SWK Holdings Corporation (“SWK”)
which provides for up to $10,000 in financing. The Company received proceeds of $5,000 at closing and may borrow an additional $5,000 upon the FDA
approval of a second product developed by the Company, excluding EM-100. Alternatively, the Company can borrow $2,000 upon FDA approval of the EM-
100 product candidate and then an additional $3,000 upon FDA approval of another one of its product candidates. The term of the SWK Credit Agreement is
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%. In connection with the SWK
Credit Agreement, the Company paid $250 in cash for issuance costs and issued warrants to SWK to purchase common stock of the Company in an amount
equal to 6.0% of the principal amounts drawn under the SWK Credit Agreement, utilizing the prior ten-day average closing price of the Company’s common
stock as a divisor to calculate the number shares issuable under the warrant. 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, will only pay interest on the debt until May 2021 and then
will pay 4.0% of the loan principal balance commencing on May 15, 2021 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.  SWK  and  the  Company  will  negotiate  covenant  targets  for
EBITDA and revenue within 180 days of the date of the SWK Credit Agreement.

In connection with the SWK Credit Agreement, the Company issued warrants to SWK to purchase 51,239 shares of the Company’s common stock
(the “SWK Warrants”) with an exercise price of $5.86 per share. The SWK Warrants are exercisable immediately and have a term of seven years. 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  relative  fair  value  of  the  SWK  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%.

The debt discount amortization recorded in 2019 was $16 and $82 was recorded for accrued interest and included in accrued liabilities.

Note 7 — Redeemable Convertible Preferred Stock — Series A

The Company has 10,000,000 authorized shares of $0.001 par value preferred stock as per its Amended and Restated Certificate of Incorporation. In
June 2017, the Company issued 6,685,082 Series A Preferred at a price of $3.00 per share and all shares remained outstanding until the Company’s IPO in
November 2018. The gross proceeds were $20,055 from the Series A Preferred stock offering. The Series A Preferred shares, including accrued and unpaid
dividends, automatically converted to the Company’s common shares at the date of the IPO (See Note 8).

As  of  the  date  of  the  IPO  on  November  15,  2018,  the  liquidation  value  of  the  Series  A  Preferred  was  $21,746,  which  consisted  of  the  issuance

amount of $20,055 plus accrued dividends of $1,691.

The Series A Preferred automatically converted to common shares upon completion of the IPO in November 2018. The conversion share calculation
was  based  on  the  $3.00  initial  issue  price  for  the  Series  A  Preferred  plus  accrued  and  unpaid  dividends,  and  automatically  converted  into  shares  of  the
Company’s common stock using a stated divisor conversion price equal to 50% of the IPO price to the public which was $6.00 per share. In accordance with
relevant accounting literature, since the terms of the conversion option did not permit the Company to compute the additional number of shares that it would
need  to  issue  upon  conversion  of  the  Series  A  Preferred  when  the  contingent  event  occurred,  the  Company  recorded  the  beneficial  conversion  amount  of
$21,747 as a deemed dividend at the date of the IPO in November 2018.

As a result of the Series A Preferred having a possible cash redemption feature in the event that an IPO or alternate financing was not completed by
December 31, 2018, the Series A Preferred was classified as temporary equity and not included as part of Company’s stockholders’ equity (deficit) prior to
the  November  2018  IPO.  In  accordance  with  that  classification,  the  $2,534  of  issuance  costs  associated  with  the  Series  A  Preferred  offering  were  being
ratably accreted as a deemed dividend using the effective interest method through the expected redemption date.

Note 8 — Common Stock

The Company has 50,000,000 authorized shares of $0.001 par value common stock as per its Amended and Restated Certificate of Incorporation. In
May  2017,  the  Company  issued  3,500,000  shares  of  its  common  stock  to  Harrow,  1,500,000  shares  of  restricted  stock  to  certain  executives  and  staff  of
Harrow and 1,000,000 shares of restricted stock to the CEO of the Company. On January 1, 2018, the Company issued 54,745 restricted shares of its common
stock to each of its four outside directors (218,980 total shares) as part of their compensation for board service to the Company in 2018. The restricted shares
issued  to  the  Harrow  executives  and  staff  vested  over  a  12-month  period,  the  restricted  shares  issued  to  the  CEO  vest  over  a  24-month  period  and  the
restricted  shares  issued  to  the  outside  directors  vested  25%  at  each  quarter-end  in  2018  and  were  fully  vested  as  of  December  31,  2018.  The  Company
accounted for the restricted stock awards (“RSAs”) in accordance with ASC 718 or ASC 505-50. For the periods ended December 31, 2019, 2018 and 2017,
the Company recorded $59, $1,388 and $1,403, respectively, in stock-based compensation expense for these RSAs (see Note 10).

In conjunction with the Company’s IPO in November 2018, the Series A Preferred shares, including accrued dividends, converted into 7,248,948
shares of the Company’s common stock, and the Company issued 4,140,000 additional shares of its common stock to investors in its IPO (See Notes 1 and 7).

During 2019, there were 97,088 warrant shares exercised (all on a cashless basis) resulting in 57,051 shares of common stock being issued by the
Company. In addition, 167,622 stock option shares were exercised and issued under the Company’s 2018 Equity Incentive Plan and 44,885 shares were issued
under the Company’s Employee Stock Purchase Program.

Note 9 — Common Stock Warrants

In May 2017, the Company issued a warrant to purchase 600,000 shares of its common stock to consultants for business strategy and intellectual
property advisory services. The warrant vested at issuance in May 2017 and has a $0.01 exercise price per warrant share and expires five years from the date
of issuance. The Company used the BSM to value the warrant and the fair value at the date of issuance was $121 based on an expected term of five years,
volatility  of  85%,  a  risk-free  interest  rate  of  1.8%  and  a  0%  rate  on  expected  dividends.  The  $121  amount  for  the  consulting  warrants  was  expensed  as  a
component of the Company’s general and administrative expenses in May 2017.

In conjunction with the closing of the Series A Preferred offering in June 2017 (see Note 7), the Company issued a warrant to purchase 649,409
shares of its common stock to the placement agent at an exercise price of $3.00 per share, provided, however, upon the conversion of the Series A Preferred,
the warrant adjusted to entitle the holder to purchase shares of common stock equal to 10.0% of the shares of common stock issuable upon conversion of the
Series A Preferred (excluding 191,000 shares of Series A Preferred that were purchased by insiders) and the exercise price would adjust to the conversion
price of the Series A Preferred. This warrant vested at issuance in June 2017. The Company used the BSM to value the warrant and the fair value at the date
of issuance was $479. Prior to the Company’s IPO in November 2018, the number of common shares issuable upon the exercise of this warrant was not fixed
as it could vary by a factor of 1.000 to 1.333 common shares per warrant share in accordance with the IPO price, and the Company considered the warrant to
be a derivative instrument. The $479 amount was recorded as a component of the issuance costs for the Series A Preferred in June 2017. As of December 31,
2017, the fair value of the warrant was $520 and the $41 increase in fair value during 2017 was recorded as a component of other income and expense.

In connection with the SWK Credit Agreement, the Company issued warrants to SWK to purchase 51,239 shares of the Company’s common stock
(the  “SWK  Warrants”)  with  an  exercise  price  of  $5.86  per  share.  The  SWK  Warrants  are  exercisable  immediately  and  have  a  term  of  seven  years  ending
November 13, 2026. 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 relative fair value of the SWK 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%. The $226 relative fair value for these
warrants was reflected as a component of paid-in-capital in the Company’s balance sheet.

As of November 15, 2018, the fair value of the warrants was $3,103 and the $2,583 increase in fair value during 2018 was recorded as a component
of other income and expense. The fair value assumptions included an expected term of five years, expected volatility of 85%, a risk-free interest rate of 2.9%
and estimate of the conversion rate. These warrants were classified as warrant liability on the Company’s balance sheets prior to the IPO in November 2018.
In connection with the Company’s IPO, the number of shares issuable upon the exercise of these warrants became fixed at 704,184 shares which eliminated
the fair value adjustment after that date. At the IPO date, the warrant liability was reclassified to additional paid-in-capital.

During November 2018, in connection with the IPO, the Company issued warrants for 414,000 shares of its common stock to the placement agent at

an exercise price of $7.50 per share.

The weighted average exercise price of the outstanding warrants for the consultant, placement agent and debt holder as of December 31, 2019 and

2018 was $3.13 and $3.04 per share, respectively.

Note 10 — Share-Based Payment Awards

The Company’s board of directors and stockholders approved the Eton Pharmaceuticals, Inc. 2017 Equity Incentive Plan in May 2017 (the “2017
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 (the “2018 Plan”) which succeeded the 2017 Plan. The Company
has granted RSAs, stock options and restricted stock units (“RSUs”) for its common stock under the 2017 Plan and 2018 Plan as detailed in the tables below.
There were 887,837 shares available for future issuance under the 2018 Plan as of December 31, 2018.

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 January
1, 2019, the share reserve was increased by 704,317 shares based on the 17,607,928 shares of common stock outstanding at December 31, 2018. The exercise
price for stock options granted is not less than the fair value of common stock as determined by the board of directors as of the date of grant. Prior to the IPO,
the  Company’s  board  of  directors  valued  the  Company’s  common  stock,  taking  into  consideration  its  most  recently  available  valuation  of  common  stock
performed by third parties as well as additional factors which might have changed since the date of the most recent contemporaneous valuation through the
date of grant. Following the IPO, the Company has used the closing stock price on the date of grant as the exercise price.

Note 10 — Share-Based Payment Awards (continued)

On January 1, 2018, the Company issued 54,745 restricted shares of its common stock to each of its four outside directors (218,980 total shares). The

restricted shares issued to the outside directors vested 25% at each quarter-end in 2018 and became fully vested at December 31, 2018.

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 periods ended December 31, 2019, 2018 and 2017, the Company’s total stock-based compensation expense was $1,888, $1,850 and $1,761,
respectively. Of these amounts, $1,574, $1,770 and $1,735 was recorded in general and administrative expenses, respectively, and $314, $80 and $26 was

NOTES TO FINANCIAL STATEMENTS
(in thousands, except share and per share amounts)

Note 10 — 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.

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 — Prior to the Company’s IPO in November 2018, the fair value of the shares of common stock underlying the stock-
based awards was determined by the board of directors, with input from management. Because there was no public market for the Company’s common stock,
the board of directors 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 the Company’s common stock performed by an unrelated third-party specialist, valuations of comparable
companies,  sales  of  the  Company’s  convertible  preferred  stock  to  unrelated  third  parties,  operating  and  financial  performance,  the  lack  of  liquidity  of  the
Company’s capital stock, and general and industry-specific economic outlook. The board of directors intended all options granted to be exercisable at a price
per share not less than the estimated per share fair value of common stock underlying those options on the date of grant. Following the IPO, the Company
uses the closing stock price on the date of grant for the fair value of the common stock.

A summary of activity for RSAs and RSUs is as follows:

Note 10 — 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  2018
Employee  Stock  Purchase  Plan  (the  “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 ending on June 10, 2019 and the second purchase period ending 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.

The Company recorded an expense of $112 and $5 in 2019 and 2018, respectively, related to the ESPP. The weighted average grant date fair value of
share  awards  in  2019  and  2018  was  $2.56  and  $2.59  per  share,  respectively.  Employees  contributed  $247  and  $8  to  the  ESPP  during  2019  and  2018,
respectively.  Of  these  amounts,  $16  and  $8  at  December  31,  2019  and  2018,  respectively,  is  included  in  accrued  liabilities  in  the  accompanying  balance
sheets.

Note 11 — 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,  warrants  and  convertible
preferred stock at December 31, 2019, 2018 and 2017 were 3,590,465, 8,262,381 and 6,977,547, 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.

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. The Company and Harrow signed licensing agreements for two products developed by Harrow whereby Harrow
assigned the product rights to the Company. The Company will pay Harrow a $50 milestone payment upon patent approval for each product and a royalty fee
at a rate of six percent on the net sales of those two products. On December 26, 2017, one of the products had its patent approved and a $50 milestone fee was
recognized  as  R&D  expense  by  the  Company  in  2017  and  paid  to  Harrow  in  January  2018.  In  July  2018,  the  Company  determined  the  patent-approved
product was not viable for its portfolio of product opportunities and Harrow paid the Company $50 to cancel the licensing agreement for the one product and
retain the product rights at Harrow.

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.

As part of the early start-up for the Company’s pharmaceutical business, key executives at Harrow received 1,500,000 shares of restricted common
stock  in  the  Company  for  consulting  services  and  certain  Harrow  managers  also  received  options  to  purchase  130,000  shares  of  common  stock  from  the
Company  (20,000  of  these  options  were  forfeited  in  2018).  The  restricted  stock  and  stock  options  vested  100%  after  one  year  on  April  30,  2018.  The
Company recorded stock-based compensation expense of $0, $970 and $1,370 for the Harrow restricted common stock and $0, $51 and $112 for Harrow
stock options, respectively, for the periods ended December 31, 2019, 2018 and 2017 as a component of its general and administrative expenses.

Additionally, the Chief Executive Officer of Harrow is a member of the Company’s board of directors.

Chief Executive Officer

The  CEO  has  a  partial  interest  in  several  companies  that  the  Company  is  working  with  for  product  development  and  potential  marketing  if  the

products are approved by the FDA as detailed 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 is responsible for all costs of testing and FDA approval of the product, other than the FDA filing fee which will be paid by Eyemax.
The Company was also 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, 2019 or 2018.

Note 12 — 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  remains  obligated  to  pay
Eyemax two milestones 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 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 on February 18, 2019 and future potential royalties on Bausch sales of EM-100, pending an FDA approval for EM-100, will be split between Eyemax
and the Company. There were no amounts due under the terms of the Amended Agreement as of December 31, 2019 or 2018.

The  Company  acquired  the  exclusive  rights  to  sell  the  DS-100  product  in  the  United  States  pursuant  to  an  exclusive  development  and  supply
agreement  (the  “Andersen  Agreement”)  dated  July  9,  2017  between  the  Company  and  Andersen  Pharma,  LLC,  an  entity  affiliated  with  the  CEO
(“Andersen”). The Company also holds an option to purchase the DS-100 product and all related intellectual property and government approvals at a price of
one dollar. Pursuant to the Andersen Agreement, Andersen is responsible for obtaining FDA approval at its expense and manufacturing the product for sale to
the Company at its cost. The Company is responsible for commercializing the product in the United States at its expense. The Company paid Andersen $750
upon execution of the Andersen Agreement, which was recorded as a component of R&D expense and will pay Andersen $750 upon successful completion of
three registration batches of product, $750 upon submission of a New Drug Application (“NDA”) and $750 upon FDA approval. The Company will also pay
Andersen 50% of the net profit from the sale of the product. The Andersen Agreement is for an initial term of five years from the first commercial sale of the
product, subject to successive two-year renewals unless either party elects to terminate the Andersen Agreement. There were no amounts due under the terms
of the Andersen Agreement as of December 31, 2019 or 2018. The aforementioned option to purchase the product and all related intellectual property and
government approvals was considered to represent variable interest in the affiliated entity. The affiliated entity was not considered to be a variable interest
entity.

The Company acquired the DS-200 product and all related intellectual property and government approvals pursuant to an asset purchase agreement
(the “Selenix Agreement”) dated June 23, 2017 between the Company and Selenix LLC (“Selenix”), an entity affiliated with the Company’s CEO. Pursuant
to the Selenix Agreement, the Company paid Selenix $1,500 at signing, which was recorded as a component of R&D expense and paid $1,500 in April 2019
upon submission of an NDA on March 13, 2019 which was reflected as a component of R&D expense for the nine-month period ended September 30, 2019.
The Company will pay $1,000 upon FDA approval of the DS-200 product. The Company has also agreed to pay Selenix 50% of the net profit from the sale of
the product for the first 10 years following the date of the Selenix Agreement. There were no amounts due under the terms of the Selenix Agreement as of
December 31, 2019 or 2018.

Note 13 — Leases

Effective January 1, 2019, the Company adopted ASC 842, which requires an entity to recognize a right-of-use (“ROU”) asset and a lease liability on
the balance sheet for substantially all leases, including operating leases, using the modified retrospective approach. The Company elected to use the package
of practicable expedients which allows companies to not reassess the following: (1) the lease classification for any expired or existing leases, (2) the treatment
of initial direct costs as they related to existing leases, and (3) whether expired or existing contracts are or contain leases. The Company did not elect the use
of the hindsight practical expedient, but did elect to separate lease components from non-lease components related to its office space lease.

Upon adoption of ASC 842, the Company had non-cancellable operating leases for its office and laboratory space subject to recognition as ROU
assets. Accordingly, on January 1, 2019 the Company recorded $281 in ROU assets and $272 in operating lease liabilities (the difference of $9 related to
existing prepaid rent as of December 31, 2018). The Company has not entered into any other lease arrangements through December 31, 2019.

Note 13 — Leases (continued)

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 runs through the end of March 2021. 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 runs through the end of February 2021.

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 not 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.  For  leases
already commenced, the lease term was determined to be the remaining months in the lease term as of January 1, 2019, the date of adoption. 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. 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 periods ended December 31, 2019, 2018 and 2017, the Company recorded $140, $115 and $14, 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 $55 and $85 for the year ended December 31, 2019. Cash paid for amounts included in the measurement of operating lease liabilities was
$120  for  year  ended  December  31,  2019.  The  ROU  asset  amortization  for  year  ended  December  31,  2019  was  $121  and  is  reflected  in  depreciation  and
amortization  in  the  Company’s  statements  of  cash  flows. As  of  December  31,  2019,  the  weighted-average  remaining  lease  term  was  1.2  years,  and  the
weighted-average incremental borrowing rate was 7.8%.

NOTES TO FINANCIAL STATEMENTS
(in thousands, except share and per share amounts)

The Tax Act significantly revised U.S. corporate income tax law by, among other things, reducing the corporate income tax rate from 34% to 21%
and  implementing  a  modified  territorial  tax  system.  Implementation  of  the  Tax  Act  resulted  in  a  $733  charge  for  the  revaluation  of  the  Company’s  net
deferred tax assets offset by a corresponding $733 reduction in the valuation reserve for income taxes during the period ended December 31, 2017.

The Company has a federal and state NOL carryforward of $31,151 as of December 31, 2019, of which $5,652 will begin to expire in 2037 and
2039, respectively. 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 and other pre-change tax attributes (such as research tax credits) to offset its post-
change  income  may  be  limited.  The  Company  is  currently  performing  a  study  to  determine  if  it  has  triggered  an  “ownership  change”  limitation  and  tax
attributions will be adjusted when the study is complete, if required.

Note 15 - Employee Savings Plan

The Company established an employee savings plan pursuant to Section 401(k) of the Internal Revenue Code, effective January 1, 2018. The plan
allows participating employees to deposit into tax deferred investment accounts up to 100% of their salary, subject to annual limits. The Company makes
certain matching contributions to the plan in amounts up to 4% of the participants’ annual cash compensation, subject to annual limits. For the periods ended
December 31, 2019, 2018 and 2017, the Company made $113, $62 and $0 in matching contributions, respectively.

Note 16 — Commitments and Contingencies

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  DS-300  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.

The Company acquired the exclusive license to develop, manufacture and sell ET-103 in the United States pursuant to an Exclusive License and
Supply Agreement dated August 3, 2018 between the Company and Liqmeds Worldwide Limited (“LMW”), an unaffiliated entity. Pursuant to the agreement,
the Company will be responsible for, and will own, all regulatory filings and approvals at its expense, provided that it shall have the right to recoup 35% of
any regulatory filing fees from the initial profits from the sale of ET-103 and, provided further, the licensor shall be responsible for any bioequivalence study
and shall be responsible for 60% of the costs of such study. An affiliate of the licensor shall manufacture the ET-103 and sell it to the Company at its cost. The
Company paid the licensor $350 upon execution of the agreement and will pay the licensor $1,500 upon the FDA’s acceptance of an NDA for review, $1,000
upon FDA approval, $1,500 upon issuance of patent covering ET-103 listed in the FDA’s Orange Book and $500 in the event of product sales in excess of
$10,000 in any calendar year. In addition, the Company is required to pay the licensor 35% of the net profit from product sales. The license agreement is for
an initial term of 10 years from the date of the first commercial sale of the product, subject to two-year renewals unless either party elects to terminate no less
than 12 months prior to the then current term. The agreement also contains customary representations, warranties, covenants and indemnities by the parties.

Note 16 — Commitments and Contingencies (continued)

On  January  23,  2019  the  Company  entered  into  a  Licensing  and  Supply  Agreement  (the  “Agreement”)  with  LMW  for  ET-104  oral  liquid,  a
development  stage  product  candidate  (“ET-104”).  Pursuant  to  the  terms  of  the  Agreement,  the  Company  will  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 will pay $325 upon the FDA’s acceptance of an NDA for review, $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 are achieved within a calendar year. In addition, the Company is required to pay the licensor 35% of the net profit from product sales. The
Agreement is for an initial term of 10 years from the date of the first commercial sale of the product. The Company will retain sole ownership of the NDA
after expiration of the Agreement

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  will  be  responsible  for  marketing  activities  and  Sintetica  is  responsible  for
development, manufacturing, and regulatory activities related to obtaining regulatory 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 will supply Biorphen to the
Company at its direct costs and the Company will retain 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.

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 ET-203, 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 refund was reflected
as a component of prepaid and other current assets on the Company’s balance sheet at December 31, 2019. The Company expects the submission will be
successfully  resubmitted  in  the  near  future  and  will  pay  the  $1,000  milestone  at  that  time.  The  Company  will  pay  $750  upon  FDA  approval  and  the
commercial sale of the product candidate. Upon approval, Sintetica will supply ET-203 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  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 ET-105, a 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 will 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 $2,000 upon FDA approval and commercial sales of the product candidate and another $1,000 upon
issuance of an Orange-book listed patent. Aucta will receive a low double-digit royalty on net sales and will be entitled to receive milestone payments of up to
$18,000 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
● $5,000 when net sales exceed $50 million in a calendar year
● $10,000 when net sales exceed $100 million in a calendar year

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.

With respect to the year ended December 31, 2019, under the supervision and with the participation of our management, we conducted an evaluation
of the effectiveness of the design and operations of our disclosure controls and procedures. Based upon this evaluation, the Company’s principal executive
officer and principal financial officer have concluded that the Company’s disclosure controls and procedures are effective.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting 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, 2019, 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, 2019.

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,  2019  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.
