Overview

 PART I

Cocrystal Pharma, Inc. (the “Company” or “Cocrystal”) is a biotechnology company seeking to discover and develop novel antiviral therapeutics as treatments for serious and/or
chronic viral diseases. We employ unique structure-based technologies and Nobel Prize winning expertise to create first- and best-in-class antiviral drugs. These technologies
are designed to efficiently deliver small molecule therapeutics that are safe, effective and convenient to administer. We have identified promising preclinical and early clinical
stage antiviral compounds for unmet medical needs including influenza, Hepatitis C virus (“HCV”), and norovirus infections.

The Company operates in one segment. Management uses cash flows as the primary measure to manage its business and does not segment its business for internal reporting or
decision-making.

Cocrystal Technology

We  are  developing  antiviral  therapeutics  that  inhibit  the  essential  replication  function  of  various  viruses.  One  of  our  goals  is  to  decrease  the  duration  of  HCV  therapy  by
advancing  drug  candidates  targeting  the  HCV  RNA-dependent  RNA  polymerase  enzyme.  Additional  goals  include  treating  human  and  avian  (bird)  influenza  virus  and
norovirus  infections  by  discovering  and  developing  drug  candidates  targeting  the  viral  replication  complex.  To  discover  and  design  these  inhibitors,  we  use  a  proprietary
platform comprising computation, medicinal chemistry, X-ray crystallography, and our extensive know-how. We determine the structures of cocrystals containing the inhibitors
bound to the enzyme or protein to guide our design. We also use advanced computational methods to screen and design product candidates using proprietary cocrystal structural
information. In designing the candidates, we seek to anticipate and avert potential viral mutations leading to resistance. By designing and selecting drug candidates that interrupt
the viral replication process and also have specific binding characteristics, we seek to develop drugs that are not only effective against both the virus and possible mutants of the
virus, but which also have reduced off-target interactions that cause undesirable clinical side effects. This approach requires an extensive knowledge of viruses and drug targets
to carry out. In addition, knowledge and experience in the fields of structural biology, and enzymology are required. We developed our proprietary structure-based drug design
under the guidance of Dr. Roger Kornberg, our Chief Scientist and recipient of the Nobel Prize in Chemistry in 2006. Our drug discovery process focuses on those parts of the
enzymes to which drugs bind and on drug-enzyme interactions at the atomic level. Additionally, we have developed proprietary targeted in-house chemical libraries of non-
nucleoside inhibitors, metal-binding inhibitors, and drug-like fragments. Our drug discovery process is different from traditional, empirical, medicinal chemistry approaches that
often  require  iterative  high-throughput  compound  screening  and  lengthy  hit-to-lead  processes.  We  continue  developing  preclinical  and  clinical  drug  candidates  using  our
proprietary drug discovery technology.

The Company’s proprietary technology integrates several powerful and specialized techniques:

(1)

(2)

(3)

Selection of viral drug targets amenable to broad-spectrum antiviral drug development and essential for viral genome replication;

Atomic resolution 3-D structure determination of drug binding pockets;

In-depth computational  analysis  of  conservation  of  drug-binding  pockets  and  critical  molecular  interactions  between  antiviral  inhibitors and  amino  acid  residues  of  the
target molecule’s drug-binding pocket;

(4)

Cocrystal structure determinations to inform hit identification, hit-to-lead, and lead optimization processes;

(5) Molecular modeling  and  computer-guided  lead  discovery  to  support  rational  chemical  modifications  based  on  structure-activity  relationships, or  SAR,  of  candidate

inhibitor compounds;

2

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(6)

(7)

Knowledge of enzymatic mechanisms to guide the design of drugs with exceptional affinity, specificity, and broad-spectrum activity; and

Platforms for rapid identification of antiviral enzyme inhibitors showing broad-spectrum antiviral capability.

We have applied these techniques to develop antiviral inhibitors of three important viruses: HCV, influenza, and norovirus.

Market-Driven Product Profiles

In all of our programs our goal is to develop best-in-class broad-spectrum antiviral drugs with high-barrier-to-drug resistance. An ideal product for an antiviral therapy would
have at least the following characteristics:

(1)

(2)

(3)

(4)

(5)

Fast onset of action and/or shortened therapeutic time;

Good safety and tolerability profile;

Effective against all viral subtypes that cause disease;

High barrier to viral resistance; and

Ease of administration, for example, a pill.

Even at the discovery stage of drug development, we select compounds with these factors in mind. Furthermore, our technology is capable of delivering therapies that satisfy all
of these key factors, as detailed below.

In order to improve patient care and penetrate the HCV marketplace, drugs are needed with faster onset of viral load reduction resulting in shorter treatment time. Current and
known future influenza treatments shorten symptoms by only about 24 hours.

Norovirus spreads readily among the affected and is in need of a fast-acting therapeutic intervention. During the discovery and development phases we focus on this important
clinical variable.

Safety and tolerability: All drugs have side effects, also referred to as adverse effects. These usually result from a drug’s ability to bind to human molecules (usually proteins).
When this interaction is intentional (i.e., part of the drug’s mechanism of action), the adverse effects are classified as on-target effects. When this interaction is unintentional
(i.e., resulting from the drug’s interaction with an unintended human molecule), the effects are called off-target effects. Our inhibitors target viral replication enzymes, which
are generally unique to viruses. Because the targets are viral, not human, minimal adverse effects are possible. During the discovery phase, we evaluate candidate compounds
for potential cross-reactivity with human replication enzymes and attempt to eliminate those compounds that are cross-reactive with humans.

Broadly effective against major strains responsible for a viral disease: For any given viral disease, there are different strains of viruses that cause the disease. For example, there
are six major strains of the virus known to cause HCV. These strains are termed “genotypes.” Each HCV genotype is common in some parts of the world and rare in others.
Also, there are three types of influenza viruses, A, B, and C. Influenza A and B viruses are significant human respiratory pathogens that cause seasonal flu. Influenza A viruses
can also cause an influenza pandemic. Influenza C is a subtype of the influenza virus that tends to cause only mild illness, and is not responsible for seasonal or pandemic
infections. Our goal is to design and develop drug candidates that will be effective on the broadest possible range of viruses causing the disease.

Many antiviral drugs available today are effective only against certain strains of viruses and less effective or not effective at all against other strains. To address this problem,
we  are  developing  drug  candidates  that  specifically  target  viral  proteins  involved  in  viral  replication.  Despite  the  various  strains  of  virus  that  may  exist,  these  replication
enzymes are essentially identical (highly conserved) among all strains of a given virus. By targeting these conserved replication enzymes, our antiviral compounds are designed
and tested to be effective against major virus strains. Replication enzymes are generally conserved not only among subtypes of a given virus but also among many different
viruses, creating an opportunity for the development of broad-spectrum antiviral drugs.

High barrier to drug resistance:  Drug  resistance  is  a  major  obstacle  to  developing  effective  antiviral  therapies.  Viruses  can  reproduce  rapidly  and  in  enormous  quantities  in
infected human cells. During viral replication, random changes in the viral genome, called mutations, spontaneously develop. If such a mutation occurs in a region of the viral
genome that is targeted by a given antiviral therapy, that therapy may no longer be effective against the mutated virus. These mutated or “resistant” viruses can freely infect and
multiply  even  in  individuals  who  have  received  drug  treatment.  In  some  cases,  resistant  virus  strains  may  even  predominate.  For  example,  in  the  2009  swine  influenza
pandemic, the predominant strain was resistant to the best available therapies.

The Company’s focus on viral replication proteins can overcome the obstacle of viral resistance. We identify and target critical components of viral replication proteins that are
essential for function, therefore, sensitive to change. A mutation in these critical components is likely to inactivate the replication protein and, in turn, render the virus incapable
of replicating. Because such mutations cannot propagate, the virus cannot effectively develop resistance to the enzyme inhibitors we employ. We test the effectiveness of our
compounds against potential viral mutations and select compounds with the highest barrier to resistance.

Ease of administration: We select compounds for development that can be administered orally, preferably once daily in pill-form.

Research and Development Update

During the year ended December 31, 2018 and to date in 2019, the Company focused its research and development efforts primarily in three areas:

Hepatitis C

CC-31244,  our  HCV  Non-Nucleoside  Polymerase  Inhibitor  (“NNI”),  is  a  potential  best-in-class  pan-genotypic  inhibitor  of  NS5B  polymerase  for  the  treatment  of  HCV
infection.  It  has  the  potential  to  be  an  important  component  in  an  all-oral  ultra-short  HCV  combination  therapy.  The  Company  filed  an  Investigational  New  Drug  (“IND”)
application with the U.S. Food and Drug Administration (“FDA”) on February 28, 2018 and received notice from the FDA on March 29, 2018 that its IND was now open and
the Company was cleared to initiate its Phase 2a clinical study evaluating CC-31244 for the treatment of HCV infected individuals.

In  June  2018,  the  Company  began  enrollment  in  and  initiation  of  patient  dosing  in  its  Phase  2a  clinical  study  evaluating  CC-31244  for  the  treatment  of  HCV  infected
individuals and completed the enrollment in September 2018. The Phase 2a open-label study was designed to evaluate the safety, tolerability and preliminary efficacy of CC-
31244  in  combination  with  Epclusa,  an  approved  HCV  drug.  Patients  are  treated  with  CC-31244  and  Epclusa  for  two  weeks  and  then  Epclusa  alone  for  an  additional  four
weeks.

On January 22, 2019 the Company announced safety and preliminary efficacy data for the Phase 2a study. All subjects had completed the six-week treatment regimen. The
treatment was well tolerated with no study discontinuations due to adverse events. Eight of 12 subjects achieved the primary efficacy endpoint of sustained virologic response at
12 weeks after completion of treatment (SVR12). SVR12 is defined as undetectable virus in blood 12 weeks after completion of treatment and is considered a virologic cure.
The trial is ongoing at the Institute of Human Virology, University of Maryland School of Medicine and final study results are expected in the second quarter of 2019.

In addition, in October 2018, the Company signed a Clinical Trial Agreement for an investigator-initiated study with the Humanity & Health Research Centre in Hong Kong,
China. Under the Clinical Trial Agreement, the Phase 2a study of CC-31244 for the treatment of HCV, which is expected to commence during the first half of 2019, will be
sponsored and conducted by the Humanity & Health Research Centre in Hong Kong under the guidance of Dr. George Lau, MBBS (HKU), M.D. (HKU), FRCP (Edin, Lond),
FHKAM (Med), FHKCP, FAASLD, Chairman of Humanity and Health Medical Centre, Hong Kong. The Company has agreed to provide CC-31244 to be used in the Phase 2a
study.

In December 2018, the Company voluntarily terminated a license agreement with Emory University covering the patents and patent applications for HCV inhibitors, which are
not essential to our HCV program. See “Item I - Business – Collaborations – Emory University Collaboration” for further information.

The Company is in partnership discussions for further clinical development of CC-31244.

Influenza

We have several preclinical candidates under development for the treatment of influenza infection. CC-42344, a novel PB2 inhibitor, has been selected as a preclinical lead.
This candidate binds to a highly conserved PB2 site of influenza polymerase complex (PB1: PB2: PA) and exhibits a novel mechanism of action. CC-42344 showed excellent
antiviral  activity  against  influenza A  strains,  including  avian  pandemic  strains  and  Tamiflu  resistant  strains,  and  has  favorable  pharmacokinetic  profiles.  We  are  currently
conducting additional preclinical IND enabling studies and plan to initiate a Phase 1 study during 2020.

In addition, novel inhibitors effective against both strains A and B have been identified and are in the preclinical stage. Several of these have potencies approaching single digit
nanomolar. On January 2, 2019, the Company entered into an Exclusive License and Research Collaboration Agreement (the “Collaboration Agreement”) with Merck Sharp &
Dohme Corp. (“Merck”) to discover and develop certain proprietary influenza A/B antiviral agents. See “Item 1 – Business – Collaborations – Merck Collaboration” for more
information.

Norovirus Infections

We continue to identify and develop non-nucleoside polymerase inhibitors using the Company’s proprietary structure-based drug design technology platform.

Therapeutic Targets

Hepatitis C: A large competitive market with opportunity for shorter treatment regimens.

HCV  is  a  highly  competitive  and  changing  market.  Currently,  the  standard  treatment  varies  with  the  genotype  of  the  HCV  infection.  Prior  to  late  2013,  treatment  included
peginterferon alpha and ribavirin, along with a protease inhibitor (either telaprevir, boceprevir, or simeprevir). In late 2013, sofosbuvir, a drug belonging to a new class of drugs
called “nucleoside analogs” or “Nucs,” was approved to treat HCV. In patients infected with HCV genotype 1 (the most common HCV genotype in the US), sofosbuvir was
administered  in  combination  with  peginterferon  alpha  and  ribavirin.  In  patients  with  HCV  genotypes  2  and  3,  however,  sofosbuvir  could  be  effectively  administered  in
combination with ribavirin, without the need for peginterferon alpha. Since 2014, several new combinations of direct-acting antiviral agents (“DAAs”) have been approved for
the treatment of HCV infection. These include Harvoni (sofosbuvir/ledipasvir) 12 weeks of treatment, Viekira Pak (ombitasvir/paritaprevir/ritonavir, dasabuvir) 12 weeks of
treatment,  Epclusa  (sofosbuvir/velpatasvir)  12  weeks  of  treatment,  Zepatier  (elbasvir/grazoprevir)  12  weeks  of  treatment  and  Mavyret  (glecaprevir/pibrentasvir)  8  weeks  of
treatment. We believe the next improvements in HCV treatment will be ultra-short treatments of four to six weeks, the goal of our program.

We anticipate a significant global HCV market opportunity that will persist through at least 2036, given the large prevalence of HCV infection worldwide. The 2017 World
Health Organization Global Hepatitis Report estimates that 71 million people worldwide have chronic HCV infections.

We are targeting the NS5B polymerase with an NNI, which could be developed as part of an all-oral, pan-genotypic combination regimen. Our focus is on developing what is
now called ultrashort treatment regimens from 4 to 6 weeks in length. Such a combination treatment CC-31244 with different classes of approved DAAs has the potential to
change the paradigm of treatment for HCV with a shorter duration of treatment. Combination strategies with approved drugs could allow us to expand CC-31244 into the HCV
antiviral therapeutic area globally and could lead to a high and fast cure rate, to improved compliance, and to reduced treatment  duration.  To  our  knowledge  no  competing
company has yet developed a short HCV treatment of less than 8 weeks with a high (>95%) sustained virologic response (SVR) at week 12.

CC-31244, an HCV NNI, is a potential best in class pan-genotypic inhibitor of NS5B polymerase for the treatment of HCV. The Company completed a Phase 1a/b study in
Canada in September 2016, with favorable safety results in a randomized, double-blinded, Phase 1a/b study in healthy volunteers and HCV-infected subjects. The Company is
presently  conducting  a  Phase  2a  study  in  HCV  genotype  1  subjects  in  the  United  States.  Cocrystal  presented  the  interim  results  from  the  Phase1a/b  study  at  the APASL  in
February 2017. HCV-infected subjects treated with CC-31244 had a rapid and marked decline in HCV RNA levels, and slow viral rebound after treatment. Results of this study
suggest that CC-31244 could be an important component in a shortened duration all-oral HCV combination therapy. Patient enrollment has been completed in the Phase 2b.
See “Item 1 – Business – Research and Development Update – Hepatitis C” for more information.

The Company is progressing clinically while seeking a partner for further clinical development of CC-31244.

Influenza: A worldwide public health problem, including the potential for pandemic disease.

Influenza is a severe respiratory illness, caused primarily by influenza A or B virus. The Centers for Disease Control and Prevention (the “CDC”) estimates that influenza was
linked to approximately 79,000 deaths and 960,000 hospitalizations in the United States during the 2017-2018 flu season. According to the report published by BCC Research in
May 2018, the worldwide market for antiviral drugs to treat influenza was valued at approximately $5.6 billion in 2017 and is expected to grow to $6.5 billion by 2022.

Currently, approved antiviral treatments for influenza are effective, but burdened with significant viral resistance. Strains of influenza virus that are resistant to the approved
treatments osteltamivir phosphate (Tamiflu(R)) and zanamavir (Relenza(R)) have appeared, and in some cases predominate. For example, the predominant strain of the 2009
swine influenza pandemic was resistant to Tamiflu. These drugs target viral neuraminidase enzymes, which are not highly conserved between viral strains. In fact, different
influenza virus strains such as H1N1 and H5N1 are named according to their respective differences in hemagglutinin (H) and neuraminidase (N).

In addition, the Company has several preclinical candidates under development for the treatment of influenza infection. CC-42344, a novel PB2 inhibitor, has been selected as a
preclinical lead. This candidate binds to a highly conserved PB2 site of the influenza polymerase complex (PB1: PB2: PA), and exhibits a novel mechanism of action. CC-42344
showed  excellent  antiviral  activity  against  influenza A  strains,  including  avian  pandemic  strains  and  Tamiflu-resistant  strains,  and  has  favorable  pharmacokinetic  profile.
Antiviral  product  candidates  that  are  competitors  for  the  Company’s  influenza  programs  are,  VX-787,  being  developed  by  Janssen,  and  S-033188,  being  developed  by
Shionogi/Roche. S-033188 was approved as Xofluza in Japan on February 23, 2018, and in US as Baloxavir Marboxil (trade name Xofluza®) on October 24, 2018. See “Item 1
– Business – Research and Development Update – Influenza” for more information.

Norovirus: A worldwide public health problem responsible for close to 90% of epidemic, non-bacterial outbreaks of gastroenteritis around the world.

Norovirus is a very common and highly contagious virus that causes symptoms of acute gastroenteritis including nausea, vomiting, stomach pain and diarrhea. Other symptoms
include  fatigue,  fever  and  dehydration.  Noroviruses  are  a  major  cause  of  gastrointestinal  illness  in  closed  and  crowded  environments,  having  become  notorious  for  their
common  occurrence  in  hospitals,  nursing  homes,  child  care  facilities,  and  cruise  ships.  In  the  United  States  alone,  noroviruses  are  the  most  common  cause  of  acute
gastroenteritis, and are estimated to cause 20 million illnesses each year and contribute to 70,000 hospitalizations and 800 deaths. Noroviruses are responsible for up to 1.1
million hospitalizations and 218,000 deaths annually in children in the developing world. In immunosuppressed patients, chronic norovirus infection can lead to a debilitating
illness with extended periods of nausea, vomiting and diarrhea. There is currently no effective treatment or effective vaccine for norovirus, and the ability to curtail outbreaks is
limited. A few companies, including Chimerix, are developing antiviral treatments for this disease and three candidate vaccines are currently in early stages of clinical testing by
GlaxoSmithKline, Ligocyte and Takeda Pharmaceuticals.

6

 
 
 
 
 
 
 
 
 
 
 
 
By targeting viral replication enzymes, we believe it is possible to develop an effective treatment for all genogroups of norovirus. Also, because of the significant unmet medical
need and the possibility of chronic norovirus infection in immunocompromised individuals, new antiviral therapeutic approaches may warrant an accelerated path to market.
The Company is developing inhibitors of the RNA-dependent RNA polymerase of norovirus. Similar to the HCV polymerases, this enzyme is essential to viral replication and
is  highly  conserved  between  all  noroviral  genogroups.  Therefore,  an  inhibitor  of  this  enzyme  might  be  an  effective  treatment  or  short-term  prophylactic  agent,  when
administered during a cruise or nursing home stay, for example. We have developed X-ray quality norovirus polymerase crystals, and have identified promising NNIs. We are
implementing the platform and approaches that have proven successful in our other antiviral programs.

Intellectual Property

Our  success  depends,  in  part,  upon  our  ability  to  protect  our  core  technology.  To  establish  and  protect  our  proprietary  rights,  we  rely  on  a  combination  of  patents,  patent
applications,  trademarks,  copyrights,  trade  secrets  and  know-how,  license  agreements,  confidentiality  procedures,  non-disclosure  agreements  with  third  parties,  employee
disclosure and invention assignment agreements, and other contractual rights.

Our patent portfolio consisted of patents and pending applications in the areas primarily related to the treatment of HCV, Influenza A, and Influenza B.

In our NS5B NNI program, our patent portfolio consists of three related families, including two granted U.S. patents and two pending U.S. patent applications. Counterpart
applications in one family are filed in various countries and regions around the world.

In  our  influenza A  program,  our  patent  portfolio  consists  of  two  related  families,  including  three  pending  U.S.  provisional  applications  and  pending  applications  in  Patent
Cooperation Treaty countries and Taiwan. In our influenza A/B program two pending U.S. provisional applications have been filed.

In our NS3 program for HepC, we have one issued U.S. patent, an allowed European application, and three pending foreign applications in Canada, China, and Japan.

Collaborations

Merck Collaboration

On January 2, 2019, we entered into an Exclusive License and Research Collaboration Agreement (the “Collaboration Agreement”) with Merck to discover and develop certain
proprietary influenza A/B antiviral agents.

Under the terms of the Collaboration Agreement, Merck is funding research and development for the program at Cocrystal and Merck, including clinical development at Merck,
and Merck is responsible for worldwide commercialization of any products derived from the collaboration. The Company received an upfront payment of $4,000,000 and is
eligible to receive milestone payments related to designated development, regulatory and sales milestones with the potential to earn up to $156,000,000, as well as royalties on
product sales.

See  “Item  1A.  Risk  Factors  -  If  our  research  collaboration  with  Merck  is  terminated  or  is  otherwise  unsuccessful,  including  failure  to  reach  milestones,  we  could  lose  the
research program funding, and would not receive milestone payments or royalties, which could materially and adversely affect our business, our ability to successfully develop
and commercialize influenza A/B product candidates and our future financial condition” for the discussion of termination provisions of the Collaboration Agreement.

Emory University Collaboration

On December 6, 2018, we notified Emory University (“Emory”) of the termination of our License Agreement with Emory, dated March 7, 2013 (the “License Agreement”).
The License Agreement covered patents and patent applications for HCV inhibitors, which we no longer consider essential to our HCV program. As part of our HCV program,
we continue to focus our efforts on CC-31244, our HCV NNI. See “Item 1 – Business ‒ Research and Development Update ‒ Hepatitis C.” The Company had the right to
terminate the License Agreement at its sole discretion upon 90 days’ prior written notice and upon payment of all amounts due Emory under the License Agreement through the
date of termination. As of the date of this Annual Report on Form 10-K, the License Agreement has been terminated, no amounts were due under the License Agreement and
none will be owed in the future.

National Institute of Health

Cocrystal has two Public Health Biological Materials License Agreements with the National Institute of Health. The original license agreements were dated August 31, 2010
and amended on November 6, 2013. The materials licensed are being used in Norovirus assays to screen potential antiviral agents in our library.

Competition

The  biotechnology  and  pharmaceutical  industries  are  subject  to  intense  and  rapidly  changing  competition  as  companies  seek  to  develop  new  technologies  and  proprietary
products. We know of several companies that have marketed or are developing products for the treatment of HCV or influenza, including Gilead Sciences, Inc. (“Gilead”),
Merck & Co., Janssen Pharmaceuticals, Inc., Bristol-Myers Squibb, Toyama Chemical Co., Shionogi/Roche and Abbvie, Inc. In particular, Gilead and Abbvie dominate the
market for HCV with an estimated combined market share greater than 85%. Their products are widely considered effective. Many of the companies developing products for
the other viral diseases that are of interest to us have substantially greater financial resources, expertise and capabilities than we do.

Government Regulation

Government authorities extensively regulate the research, development, testing, manufacturing and commercialization of drug products. Any product candidates we develop
must be approved by the U.S. Food and Drug Administration (“FDA”) before they may be legally marketed in the U.S., and by the appropriate foreign regulatory agencies
before  they  may  be  legally  marketed  in  other  countries.  The  clinical  testing  of  product  candidates  to  establish  their  safety  and  efficacy  in  humans  is  subject  to  substantial
statutory and regulatory requirements with which we must comply.

Employees

As  of April  1,  2019,  we  employed  10  full-time  employees.  Of  these  full-time  employees,  eight  are  engaged  in  research  and  development  activities.  In  addition,  we  have
contracts  with  Clinical  Research  Organizations  (“CROs”),  Contract  Manufacturing  Organizations  (“CMOs”)  and  consultants  to  provide  chemistry,  toxicology,  preclinical,
clinical, regulatory work on our programs.

Corporate History

The Company was formerly incorporated in Nevada under the name Biozone Pharmaceuticals, Inc. (“Biozone”). On January 2, 2014, Biozone sold substantially all of its assets
to MusclePharm Corporation, and, on the same day, merged with Cocrystal Discovery, Inc. (“Discovery”) in a transaction accounted for as a reverse merger. Following the
merger, the Company assumed Discovery’s business plan and operations. On March 18, 2014, the Company reincorporated in Delaware under the name Cocrystal Pharma, Inc.

On November 25, 2014, a subsidiary of the Company and affiliated entities completed a series of merger transactions. As a result, a subsidiary of the Company merged with
RFS Pharma, LLC, a Georgia limited liability company (RFS Pharma”).

 Item 1A. Risk Factors.

You should consider carefully the following risk factors, together with all of the other information included or incorporated in this Annual Report. Each of these risk factors,
either alone or taken together, could adversely affect our business, operating results and financial condition, and adversely affect the value of an investment in our common
stock. There may be additional risks that we do not know of or that we believe are immaterial that could also impair our business and financial position.

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the following risk factors before deciding whether to invest in the Company. If any
of the events discussed in the risk factors below occur, our business, financial condition, results of operations or prospects could be materially and adversely affected. In such
case, the value and marketability of the common stock could decline.

RISKS RELATED TO OUR FINANCIAL CONDITION AND NEED FOR ADDITIONAL CAPITAL

We have never generated revenue from product sales and expect that due to the regulatory constraints on a drug development company with products in the pre-
clinical and early clinical stages, we may never generate revenue from product sales and may continue to incur significant losses for the foreseeable future.

We are a pre-clinical and early stage clinical, biopharmaceutical discovery and development company. From inception until 2016, our operations were limited to organizing and
staffing the Company, acquiring and developing intellectual property rights, developing our technology platform, undertaking basic research on viral replication enzyme targets
and conducting preclinical studies for our initial programs. We currently have only one product candidate in a Phase 2a clinical trial. Because of the need to complete clinical
trials, establish safety and efficacy and obtaining regulatory approval, which is an expensive and time-consuming process, we do not anticipate generating revenue from product
sales for at least five years and will continue to sustain considerable losses. We may develop a partnership that could generate income sooner, but there is no guarantee that will
be achievable.

To date, we have devoted the majority of our financial resources to research and development. We have financed our operations primarily through the sale of equity securities
and entering into research collaborations. The results of our operations will depend, in part, on the rate of future expenditures and our ability to obtain funding through equity or
debt financings, strategic alliances or grants. We anticipate our expenses will increase substantially if and as we continue our research and clinical and preclinical development
of our product candidates. We anticipate that if we continue to undertake clinical studies our expenses will increase even further.

We  have  lost  $187  million  from  inception  through  December  31,  2018  and  expect  to  continue  losing  money  in  the  future.  We  may  never  achieve  income  from
operations or have positive cash flow from operations.

As an early stage drug development company, our focus is on developing product candidates, obtaining regulatory approvals and commercializing pharmaceutical products. As
a result, we have lost $187 million from inception through December 31, 2018, expect losses to continue, and have never generated revenue from product sales. It is likely that
we will need to raise money again in the future. We cannot assure you that we will ever generate income from operations or have positive cash flow from operations.

Our ability to continue as a going concern is in doubt.

We anticipate that we will continue to lose money for the foreseeable future. Based on cash on hand as of March 29, 2019 of approximately $8,700,000, the Company may not
have the capital to finance its operations, including any unforeseen expenses such as higher than anticipated legal costs and uninsured catastrophe, for the next 12 months. The
Company has incurred net losses and negative operating cash flows since inception. For the year ended December 31, 2018, the Company recorded a net loss of approximately
$49,048,000  and  used  approximately  $8,290,000  of  cash  in  operating  activities.  The  Company  has  not  yet  established  an  ongoing  source  of  revenue  sufficient  to  cover  its
operating costs and allow it to continue as a going concern. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. If we are
unable to continue as a going concern, our stockholders will likely lose all of their investment in the Company.

Because we have yet to generate any revenue from product sales on which to evaluate our potential for future success and to determine if we will be able to execute our
business plan, it is difficult to evaluate our future prospects and the risk of success or failure of our business.

Our ability to generate revenue from product sales and achieve profitability depends on our ability, alone or with partners, to successfully complete the development of, obtain
the  regulatory  approvals  for  and  commercialize  pharmaceutical  product  candidates.  We  have  no  pharmaceutical  product  candidates  that  have  generated  any  commercial
revenue,  do  not  expect  to  generate  revenues  from  the  commercial  sale  of  pharmaceutical  products  for  many  years,  and  might  never  generate  revenues  from  the  sale  of
pharmaceutical products. Our ability to generate revenue and achieve profitability will depend on, among other things, the following:

● identifying and validating new therapeutic strategies;

9

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● entering into collaborations with large pharmaceutical on biotechnology companies, similar to our recently announced Collaboration Agreement with Merck;

● completing our research and preclinical development of pharmaceutical product candidates;

● initiating and completing clinical trials for pharmaceutical product candidates;

● seeking and obtaining regulatory marketing approvals for pharmaceutical product candidates that successfully complete clinical trials;

● establishing and maintaining supply and manufacturing relationships with third parties;

● launching and  commercializing  pharmaceutical  product  candidates  for  which  we  obtain  regulatory  marketing  approval,  with  a  partner  or, if  launched

independently, successfully establishing a sales force, marketing and distribution infrastructure;

● maintaining, protecting, enforcing, defending and expanding our intellectual property portfolio; and

● attracting, hiring and retaining qualified personnel.

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we cannot predict the timing or amount of increased expenses and when
we will be able to achieve or maintain profitability, if ever. Our expenses could increase beyond expectations if we are required by regulatory agencies to perform unanticipated
studies and trials.

Even if one or more pharmaceutical product candidates we independently develop is approved for commercial sale, we anticipate incurring significant costs associated with
commercializing any approved pharmaceutical product candidate. Moreover, if we can generate revenues from the sale of any approved pharmaceutical products, we may not
become profitable and may need to obtain additional funding to continue operations.

Because early stage drug development requires major capital investment, as we continue to incur operating losses, we will need to raise additional capital or form
strategic partnerships to support our research and development activities in the future.

We are still in the early stages of development of our product candidates and have no products approved for commercial sale. Developing pharmaceutical products, including
conducting preclinical studies and clinical trials, is capital-intensive. As a rule, research and development expenses increase substantially as we advance our product candidates
toward clinical programs. We currently have one hepatitis C product candidate in an investigator-sponsored Phase 2a clinical trial and have secured funding of the research and
development of influenza A/B product candidates under our Collaboration Agreement with Merck. See “Item 1 – Business – Collaborations – Merck Collaboration.” However,
in order to conduct trials for our other product candidates, we will need to raise additional capital to support our operations or form partnerships, in addition to our existing
collaborative alliances, which may give substantial rights to a partner. Such funding or partnerships may not be available to us on acceptable terms, or at all. Moreover, any
future financing may be very dilutive to our existing stockholders.

As we move lead compounds through toxicology and other preclinical studies, also referred to as nonclinical studies, we have and we will be required to file an Investigational
New Drug application (“IND”) or its equivalent in foreign countries, and as we conduct clinical development of product candidates, we may have adverse results that may cause
us to consume additional capital. Our partners may not elect to pursue the development and commercialization of our product candidates subject to our respective agreements
with  them.  These  events  may  increase  our  development  costs  more  than  we  expect.  We  may  need  to  raise  additional  capital  or  otherwise  obtain  funding  through  strategic
alliances if we initiate clinical trials for new product candidates other than programs currently partnered. We will require additional capital to obtain regulatory approval for, and
to commercialize, product candidates.

10

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  securing  additional  financing,  such  additional  fundraising  efforts  may  divert  our  management’s  attention  from  our  day-to-day  activities,  which  may  adversely  affect  our
ability to develop and commercialize product candidates. We cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all.
If we cannot raise additional capital when required or on acceptable terms, we may be required to:

●

●

●

significantly delay, scale back or discontinue the development or commercialization of any product candidates;

seek strategic  alliances  for  research  and  development  programs  at  an  earlier  stage  than  otherwise  would  be  desirable  or  on  terms less  favorable  than  might
otherwise be available; or

relinquish or  license  on  unfavorable  terms,  our  rights  to  technologies  or  any  product  candidates  we  otherwise  would  seek  to  develop  or commercialize
ourselves.

If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we will be prevented from pursuing development and commercialization efforts,
which will have a material adverse effect on our business, operating results and prospects or may render the Company unable to continue operations.

Because, we are unable to rely on certain exemptions from registration under the federal securities laws, as the result of a “disqualifying event” involving a director of
the Company, it could materially and adversely affect our ability to obtain future financing.

On January 10, 2019, Dr. Frost, one of our directors, was permanently enjoined from violating a certain anti-fraud provision of the Securities Act of 1933, future violations of
Section  13(d)  of  the  Exchange Act  and  Rule  13d-1(a)  thereunder,  and  participating  in  penny  stock  offerings  with  certain  exceptions.  So  long  as  Dr.  Frost  is  a  director,  the
Company will be unable to rely on certain exemptions from registration including the exemptions under Regulation A and Rule 506 promulgated under the Securities Act absent
a waiver issued by the Securities and Exchange Commission (the “SEC”). We have not applied for a waiver, and even if we do, the SEC may choose not to grant us a waiver.
While  there  is  a  statutory  exemption  for  private  placements  under  Section  4(a)(2)  of  the  Securities Act,  the  absence  of  the  Rule  506  safe  harbor  under  Regulation  D  could
adversely affect our ability to raise necessary financing in the future on terms favorable to us, or at all.

SEC regulations limit the amount of funds we may raise during any 12-month period pursuant to our shelf registration Statement on Form S-3.

Under General Instruction I.B.6 to Form S-3 (the “Baby Shelf Rule”), the amount of funds we can raise through primary public offerings of securities in any 12-month period
using our registration statement on Form S-3 is limited to one-third of the aggregate market value of the voting and non-voting common equity held by non-affiliates of the
Company. As of March 29, 2019, our public float was approximately $45 million, based on 16,406,468 shares of outstanding common stock held by non-affiliates and a price
of $2.73 per share, which was the last reported sale price of our common stock on The Nasdaq Capital Market on March 29, 2019. We therefore are limited by the Baby Shelf
Rule as of the filing of this Annual Report on Form 10-K, until such time as our public float exceeds $75 million. If we are required to file a new registration statement on
another form, we may incur additional costs and be subject to delays due to review by the SEC Staff. Further, if there is another government shutdown affecting the SEC, any
delays could adversely affect our ability to raise capital in a registered public offering.

RISKS RELATED TO OUR RELIANCE ON THIRD PARTIES

We will depend substantially on Merck for the successful research, development and commercialization of our influenza A/B product candidates.

In  January  2019,  we  entered  into  the  Collaboration Agreement  with  Merck  to  research,  develop,  and  commercialize  certain  proprietary  influenza A/B  antiviral  agents.  See
“Item  1  –  Business  –  Collaborations  –  Merck  Collaboration”  for  more  information  on  the  Collaboration Agreement.  The  success  of  this  collaborative  alliance  will  depend
substantially on the efforts and activities of Merck. Pursuant to the Collaboration Agreement, in case the joint research committee overseeing the research program cannot reach
an  agreement,  the  ultimate  decision-making  authority  is  vested  in  Merck  as  to  most  matters.  Furthermore,  Merck  will  be  solely  responsible  for  the  development  and
commercialization of any products derived from the collaboration.

11

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition, during the term of the research program and for a period of 12 months following the expiration or termination of the research program under the Collaboration
Agreement,  we  have  agreed  to  work  exclusively  with  Merck  on  the  research  and  development  of  influenza  A/B  antiviral  agents.  During  the  term  of  the  Collaboration
Agreement, we will be unable to conduct, or enable third parties to conduct, research, development and commercialization activities related to such agents. These restrictions
may impair our ability to pursue research, development and commercialization opportunities that we would otherwise deem to be beneficial to our business.

If  our  research  collaboration  with  Merck  is  terminated  or  is  otherwise  unsuccessful,  including  failure  to  reach  milestones,  we  could  lose  the  research  program
funding,  and  would  not  receive  milestone  payments  or  royalties,  which  could  materially  and  adversely  affect  our  business,  our  ability  to  successfully  develop  and
commercialize influenza A/B product candidates and our future financial condition.

Pursuant to the terms of the Collaboration Agreement, Merck agreed to, among other things, (i) fund the research and development collaboration, including clinical development
and  commercialization;  (ii)  make  certain  milestone  payments  up  to  a  total  of  $156  million,  including  payments  associated  with  the  successful  product  development  and
attainment of certain U.S. and EU regulatory approvals for the developed products and sales volume; and (iii) pay royalties on net sales of the products.

Merck can terminate the Collaboration Agreement at any time prior to the first commercial sale of the first product developed under the Collaboration Agreement, in its sole
discretion,  without  cause.  Furthermore,  research  collaborations,  including  the  Collaboration Agreement,  may  turn  out  to  be  unsuccessful  and  are  subject  to  certain  risks,
including the following risks:

●

●

●

●

disagreements with Merck resulting in delays or termination of the research, development or commercialization of product candidates, or litigation;

change the focus by Merck of its development and commercialization efforts;

failure by Merck to commit sufficient resources to the testing, marketing, distribution or development of product candidates; and

development by Merck of alternative products either on its own or in collaboration with others, or conflicts of interest or changes in business strategy or
other business issues, which could adversely affect its willingness or ability to fulfill their obligations to us.

If our collaboration with Merck is unsuccessful for these or other reasons, or is otherwise terminated for any reason, we may lose the research program funding, and would not
receive the milestone payments or royalties under the Collaboration Agreement.

Further,  pursuant  to  the  Collaboration Agreement  Merck  will  only  be  obligated  to  make  many  of  the  milestone  payments  if  our  influenza A/B  product  receives  required
regulatory  approvals,  is  commercialized  and  net  sales  exceed  the  thresholds  set  forth  in  the  Collaboration Agreement. Achieving  the  milestones  may  be  difficult  and  time-
consuming. If some or all of these goals are not achieved, we may not receive some or all of the milestone payments under the Collaboration Agreement.

Any of the foregoing could have a material adverse effect on our business, our ability to successfully develop and commercialize influenza A/B product candidates and our
future financial condition.

12

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If we form strategic alliances which are unsuccessful or are terminated, we may be unable to develop or commercialize certain product candidates and we may be
unable to generate revenues from our development programs.

In addition to the Collaboration Agreement with Merck, we are likely to use third-party alliance partners for financial, scientific, manufacturing, marketing and sales resources
for  the  clinical  development  and  commercialization  of  certain  of  our  product  candidates.  These  strategic  alliances  will  likely  constrain  our  control  over  development  and
commercialization  of  our  product  candidates,  especially  once  a  candidate  has  reached  the  stage  of  clinical  development.  Our  ability  to  recognize  revenues  from  successful
strategic alliances may be impaired by several factors including:

●

●

●

●

●

●

●

●

●

●

a partner may shift its priorities and resources away from our programs due to a change in business strategies, or a merger, acquisition, sale or downsizing
of its company or business unit;

a partner may cease development in therapeutic areas which are the subject of our strategic alliances;

a partner may change the success criteria for a program or product candidate delaying or ceasing development of such program or candidate;

a significant delay in initiation of certain development activities by a partner could also delay payment of milestones tied to such activities, impacting our
ability to fund our own activities;

a partner could develop a product that competes, either directly or indirectly, with an alliance product;

a partner with commercialization obligations may not commit sufficient financial or human resources to the marketing, distribution or sale of a product;

a partner with manufacturing responsibilities may encounter regulatory, resource or quality issues and be unable to meet demand requirements;

a partner may exercise its rights under the agreement to terminate a strategic alliance, including termination without cause;

a dispute may arise between us and a partner concerning the research, development or commercialization of a program or product candidate resulting in a
delay in milestones, royalty payments or termination of a program and possibly resulting in costly litigation or arbitration which may divert management
attention and resources; and

a partner  may  use  our  proprietary  information  or  intellectual  property  to  invite  litigation  from  a  third-party  or  fail  to  maintain or  prosecute  intellectual
property rights possibly jeopardizing our rights in such property.

Termination of a strategic alliance may require us to seek out and establish alternative strategic alliances with third-party partners. This may not be possible, including due to
restrictions under the terms of our existing collaborations, or we may not be able to do so on terms acceptable to us. See “Item 1A – Risk Factors ‒ We will depend substantially
on Merck for the successful research, development and commercialization of our influenza A/B product candidates.” If we fail to establish alternative strategic alliances with
third-party partners on terms acceptable to us, or at all, we may be required to limit the size or scope of one or more of our programs or decrease our expenditures and seek
additional funding by other means. Such events would likely have a material adverse effect on our results of operations and financial condition.

We  expect  to  rely  on  third  parties  to  conduct  some  or  all  aspects  of  our  compound  formulation,  research  and  preclinical  testing,  and  those  third  parties  may  not
perform satisfactorily.

We do not expect to independently conduct most and certainly not all aspects of our drug discovery activities, compound formulation research or preclinical testing of product
candidates.  We  rely  and  expect  to  continue  to  rely  on  third  parties  to  conduct  some  aspects  of  our  preclinical  testing  and  on  third-party  Clinical  Research  Organizations
(“CROs”) to conduct clinical trials.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If these third parties terminate their engagements, we will need to enter into alternative arrangements which would delay our product development activities. Our reliance on
these third parties for research and development activities will reduce our control over these activities but will not relieve us of our responsibilities. If in the future, we elect to
develop and commercialize any product candidates on our own, we will remain responsible for ensuring that each of our IND-enabling preclinical studies and clinical trials are
conducted under the respective study plans and trial protocols.

If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our studies under regulatory requirements or our stated study
plans and protocols, we will not be able to complete, or may experience delays in completing, the necessary clinical trials and preclinical studies to enable us or our partners to
select  viable  product  candidates  for  IND  submissions  and  will  not  be  able  to,  or  may  be  delayed  in  our  efforts  to,  successfully  develop  and  commercialize  such  product
candidates.

Because  we  intend  to  rely  on  third-party  manufacturers  to  produce  our  preclinical  and  clinical  supplies,  and  commercial  supplies  of  any  approved  product
candidates, we will subject to a variety of risks.

Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured the product candidates ourselves, including:

●

●

●

●

●

●

●

●

●

●

●

●

●

the inability to meet any product specifications and quality requirements consistently;

a delay or inability to procure or expand sufficient manufacturing capacity;

manufacturing and product quality issues related to scale-up of manufacturing;

costs and validation of new equipment and facilities required for scale-up;

a failure to comply with cGMP and similar foreign standards;

the inability to negotiate manufacturing agreements with third parties under commercially reasonable terms;

termination or nonrenewal of manufacturing agreements with third parties in a manner or that is costly or damaging to us;

the reliance  on  a  few  sources,  and  sometimes,  single  sources  for  raw  materials,  such  that  if  we  cannot  secure  a  sufficient  supply of  these  product
components, we cannot manufacture and sell product candidates in a timely fashion, in sufficient quantities or under acceptable terms;

the lack of qualified backup suppliers for any raw materials currently purchased from a single source supplier;

operations of our third-party manufacturers or suppliers could be disrupted by conditions unrelated to our business or operations, including the bankruptcy
of the manufacturer or supplier;

carrier disruptions or increased costs beyond our control;

misappropriation of our proprietary technology for the purpose of manufacturing a “generic” version of our product or sale of our product to organizations
that distribute and sell counterfeit goods, including drugs; and

failing to deliver products under specified storage conditions and in a timely manner.

14

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
These events could lead to clinical study delays or failure to obtain regulatory approval, or impact our ability to successfully commercialize future products. Some of these
events could be the basis for regulatory actions, including injunction, recall, seizure or total or partial suspension of production.

Because we expect to rely on limited sources of supply for the drug substance and drug product of product candidates, any disruption in the chain of supply may
cause a delay in developing and commercializing these product candidates.

We intend to establish manufacturing relationships with a limited number of suppliers to manufacture raw materials, the drug substance, and the drug product of any product
candidate for which we are responsible for preclinical or clinical development. Each supplier may require licenses to manufacture such components if such processes are not
owned  by  the  supplier  or  in  the  public  domain. As  part  of  any  marketing  approval,  a  manufacturer  and  its  processes  must  be  qualified  by  the  FDA  or  foreign  regulatory
authorities prior to commercialization. If supply from the approved vendor is interrupted, there could be a significant disruption in commercial supply. An alternative vendor
would  need  to  be  qualified  through  an  NDA  or  marketing  authorization  supplement,  which  could  cause  further  delay.  The  FDA  or  other  regulatory  agencies  outside  of  the
United States may also require additional studies if a new supplier is relied upon for commercial production.

These factors could cause the delay of clinical trials, regulatory submissions, required approvals or commercialization of our product candidates, cause us to incur higher costs
and  prevent  us  from  commercializing  our  products  successfully.  Furthermore,  if  our  suppliers  fail  to  deliver  the  required  commercial  quantities  of  drug  substance  or  drug
product  on  a  timely  basis  and  at  commercially  reasonable  prices,  and  we  are  unable  to  secure  one  or  more  replacement  suppliers  capable  of  production  at  a  substantially
equivalent cost, our clinical trials may be delayed or we could lose potential revenue.

Manufacturing issues may arise that could increase product and regulatory approval costs or delay commercialization.

As  third  parties  scale  up  manufacturing  of  product  candidates  and  conduct  required  stability  testing,  product,  packaging,  equipment  and  process-related  issues  may  require
refinement  or  resolution  to  proceed  with  any  clinical  trials  and  obtain  regulatory  approval  for  commercial  marketing.  We  or  the  manufacturers  may  identify  significant
impurities or stability problems, which could cause increased scrutiny by regulatory agencies, delays in clinical programs and regulatory approval, significant increases in our
operating expenses, or failure to obtain or maintain approval for product candidates or any approved products.

We rely and expect to continue to rely on third parties to conduct, supervise and monitor our clinical trials, and if those third parties perform in an unsatisfactory
manner, it may harm our business.

We rely and expect to continue to rely on CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials. While we have agreements governing the
activities of such CROs and clinical trial sites, we or our partners will have limited influence over their actual performance. Nevertheless, we or our partners will be responsible
for ensuring that each of our clinical trials is conducted in accordance with its protocol, and that all legal, regulatory and scientific standards are met. Our reliance on the CROs
does not relieve us of our regulatory responsibilities.

We, our partners and our CROs must comply with current Good Clinical Practices (“cGCPs”), as defined by the FDA and the International Conference on Harmonization, for
conducting, recording and reporting the results of IND-enabling preclinical studies and clinical trials, to ensure that data and reported results are credible and accurate and that
the  rights,  integrity  and  confidentiality  of  clinical  trial  participants  are  protected.  The  FDA  enforces  these  cGCPs  through  periodic  inspections  of  trial  sponsors,  principal
investigators and clinical trial sites. If we or our CROs fail to comply with cGCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or
other regulators may require us to perform additional clinical trials before approving any marketing applications. Our clinical trials will require a sufficiently large number of test
subjects to evaluate the safety and effectiveness of a product candidate. If our CROs fail to comply with these regulations or fail to recruit a sufficient number of patients, fail to
recruit properly qualified patients or fail to properly record or maintain patient data, we may be required to repeat such clinical trials, which would delay the regulatory approval
process.

Our contracted CROs will not be our employees, and we cannot control whether they devote sufficient time and resources to our clinical and nonclinical programs. These CROs
may  also  have  relationships  with  other  commercial  entities,  including  our  competitors,  for  whom  they  may  also  be  conducting  clinical  trials,  or  other  drug  development
activities that could harm our competitive position. If our CROs do not successfully carry out their contractual duties or obligations, fail to meet expected deadlines, or if the
quality or accuracy of the clinical data they obtain is compromised due to failing to adhere to our clinical protocols or regulatory requirements, or for any other reasons, our
clinical  trials  may  be  extended,  delayed  or  terminated,  and  we  may  not  obtain  regulatory  approval  for,  or  successfully  commercialize  our  product  candidates.  Our  financial
results and the commercial prospects for such products and any product candidates we develop would be harmed, our costs could increase, and our ability to generate revenues
could be delayed.

We also expect to rely on other third parties to store and distribute drug products for any clinical trials we may conduct. Any performance failure by our distributors could delay
clinical  development  or  marketing  approval  of  our  product  candidates  or  commercialization  of  our  products,  if  approved,  producing  additional  losses  and  depriving  us  of
potential product revenue.

RISKS RELATED TO THE DISCOVERY AND DEVELOPMENT OF PRODUCT CANDIDATES

Because the approach we are taking to discover and develop drugs is novel, it may never lead to marketable products.

We  are  concentrating  our  antiviral  therapeutic  product  research  and  development  efforts  using  our  proprietary  technology,  and  our  future  success  depends  on  the  continued
successful development of this technology and the products derived from it. We have no drug products commercialized. The scientific discoveries that form the basis for our
efforts to discover and develop drug product candidates are relatively new and unproven. The scientific evidence to support the feasibility of developing product candidates
based on our approach is limited. If we do not successfully develop and commercialize drug product candidates based upon our technological approach, we may not become
profitable and the value of our stock may decline.

15

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Further, our focus on the Company’s technology for developing drugs, as opposed to relying entirely on more standard technologies for drug development, increases the risks
associated with the ownership of our stock. If we are unsuccessful in developing any product candidates using the Company’s technology, we may be required to change the
scope and direction of our product development activities. We may not successfully identify and implement an alternative product development strategy and may as a result
cease operations.

If we do not succeed in our efforts to identify or discover potential product candidates, your investment may be lost.

The  success  of  our  business  depends  primarily  upon  our  ability  to  identify,  develop  and  commercialize  antiviral  drug  products,  an  extremely  risky  business.  Our  research
programs may initially show promise in identifying potential product candidates, yet fail to yield product candidates for clinical development for several reasons, including:

●

●

our research methodology or that of our partners may be unsuccessful in identifying potential product candidates;

potential product candidates may have harmful side effects or may have other characteristics that may make the products unmarketable or unlikely to receive
marketing approval; and

● we or our partners may change their development profiles for potential product candidates or abandon a therapeutic area.

Such events may force us to abandon our development efforts for a program or programs, which would have a material adverse effect on our business and could cause us to
cease operations. Research programs to identify new product candidates require substantial technical, financial and human resources. We may focus our efforts and resources on
potential programs or product candidates that ultimately prove to be unsuccessful.

Because our future commercial success depends on gaining regulatory approval for our products, we cannot generate revenue without obtaining approvals.

Our long-term success and generation of revenue will depend upon the successful development of new products from our research and development activities, including those
licensed or acquired from third parties. Product development is very expensive and involves a high degree of risk. Only a small number of research and development programs
result in the commercialization of a product. The process for obtaining regulatory approval to market a product like our hepatitis C or influenza products is expensive, takes
many years, and can vary substantially based on the type, complexity, and novelty of the product candidates involved. Our ability to generate revenues would be adversely
affected if we are delayed or unable to successfully develop our products.

We cannot guarantee that any marketing application for our product candidates will be approved. If we do not obtain regulatory approval of our products or we are significantly
delayed or limited in doing so, we cannot generate revenue, and we may need to significantly curtail operations.

If we are unable to successfully complete preclinical testing and clinical trials of our product candidates or experience significant delays in doing so, our business will
be materially harmed.

We intend to invest a significant portion of our efforts and financial resources in the identification and preclinical development of product candidates that target viral replication
enzymes. Our ability to generate product revenues, which we do not expect will occur for many years, if ever, will depend heavily on the successful development and eventual
commercialization of our product candidates.

16

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The commercial success of our product candidates will depend on several factors, including:

●

●

●

●

●

successful completion of preclinical studies and clinical trials;

receipt of marketing and pricing approvals from regulatory authorities;

obtaining and maintaining patent and trade secret protection for product candidates;

establishing and maintaining manufacturing relationships with third parties or establishing our own manufacturing capability; and

commercializing our products, if and when approved, whether alone or in collaboration with others.

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully complete development of, or
to  successfully  commercialize,  our  product  candidates,  which  would  materially  harm  our  business.  Most  pharmaceutical  products  that  do  overcome  the  long  odds  of  drug
development and achieve commercialization still do not recoup their cost of capital. If we are unable to design and develop each drug to meet a commercial need far in the
future, the approved drug may become a commercial failure and our investment in those development and commercialization efforts will have been commercially unsuccessful.

We  may  be  unable  to  demonstrate  safety  and  efficacy  of  our  product  candidates  to  the  satisfaction  of  regulatory  authorities  or  we  may  incur  additional  costs  or
experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates.

Before obtaining marketing approval from regulatory authorities for the sale of product candidates, we or our partners must conduct extensive preclinical studies and clinical
trials  to  demonstrate  the  safety  and  efficacy  of  the  product  candidates  in  humans.  Clinical  trials  are  expensive,  difficult  to  design  and  implement,  can  take  many  years  to
complete and are uncertain as to outcome. A failure of one or more clinical trials can occur at any stage of testing. The outcome of preclinical studies and early clinical trials
may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not predict final results. Moreover, preclinical and clinical data are often
susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical
trials have nonetheless failed to obtain marketing approval for their products.

Events that may cause a delay or unsuccessful completion of clinical development include, as examples:

●

●

●

●

●

●

●

●

●

●

●

delays in agreeing with the FDA or other regulatory authorities on final clinical trial design;

imposition of a clinical hold following an inspection of our clinical trial operations or trial sites by the FDA or other regulatory authorities;

delays in agreeing on acceptable terms with prospective contract research organizations, or CROs, and clinical trial sites;

delays in obtaining required institutional review board approval at each clinical trial site;

delays in recruiting suitable patients to participate in a trial;

delays in the testing, validation, manufacturing and delivery of the product candidates to the clinical sites;

delays in having patients complete participation in a trial or return for post-treatment follow-up;

delays caused by patients dropping out of a trial due to product side effects or disease progression;

clinical sites dropping out of a trial to the detriment of enrollment;

time required to add new clinical sites; or

delays by our contract manufacturers in producing and delivering sufficient supply of clinical trial materials.

17

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If we or our partners must conduct additional clinical trials or other testing of any product candidates beyond those that are contemplated, or are unable to successfully complete
clinical trials or other testing of any of our product candidates, or if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns,
we or our partners may:

●

●

●

●

●

●

be delayed in obtaining marketing approval for our product candidates;

not obtain marketing approval at all;

obtain approval for indications or patient populations not as broad as intended or desired;

obtain approval with labeling that includes significant use or distribution restrictions or safety warnings;

be subject to additional post-marketing testing requirements; or

remove the product from the market after obtaining marketing approval.

Our product development costs will also increase if we experience delays in testing or in obtaining marketing approvals. We do not know whether any clinical trials will begin as
planned, will need to be restructured or will be completed on schedule, if at all. Significant clinical trial delays also could shorten any periods during which we may have the
exclusive right to  commercialize  our  product  candidates  or  allow  our  competitors  to  bring  products  to  market  before  we  do,  which  would  impair  our  ability  to  successfully
commercialize  our  product  candidates  and  may  harm  our  business  and  results  of  operations. Any  inability  to  successfully  complete  preclinical  and  clinical  development,
whether independently or with our partners, could cause additional costs to us or impair our ability to generate revenues from our product candidates, including product sales,
milestone payments, profit sharing or royalties.

Our product candidates may cause adverse effects or have other properties that could delay or prevent their regulatory approval or limit the scope of any approved
label or market acceptance.

Adverse events (“AEs”) or serious adverse events (SAEs”), that may be observed during clinical trials of our product candidates could cause us, other reviewing entities, clinical
trial sites or regulatory authorities to interrupt, delay or halt such trials and could cause denial of regulatory approval. If AEs or SAEs are observed in any clinical trials of our
product candidates, including those our partners may develop under alliance agreements, our or our partners’ ability to obtain regulatory approval for product candidates may
be negatively impacted.

Serious or unexpected side effects caused by an approved product could result in significant negative consequences, including:

●

regulatory authorities  may  withdraw  prior  approval  of  the  product  or  impose  restrictions  on  its  distribution  in  the  form  of  a  modified risk  evaluation  and
mitigation strategy;

● we may be required to add labeling statements, such as warnings or contraindications;

● we may be required to change the way the product is administered or conduct additional clinical trials;

● we could be sued and held liable for harm caused to patients; and

●

our reputation may suffer.

These  events  could  prevent  us  or  our  partners  from  achieving  or  maintaining  market  acceptance  of  the  affected  product  and  could  substantially  increase  the  costs  of
commercializing our products and impair our ability to generate revenues from the commercialization of these products either by us or by our partners.

Following regulatory approval for a product candidate, we will still face extensive regulatory requirements and the approved product may face future development
and regulatory difficulties.

Even if we obtain regulatory approval in the United States or elsewhere, the applicable regulators may still impose significant restrictions on the indicated uses or marketing of
our product candidates, or impose ongoing requirements for potentially costly post-approval studies or post-market surveillance. The following discussion is based on United
States law. Similar types of regulatory provision apply outside of the United States.

The holder of an approved New Drug Application (“NDA”), must monitor and report AEs and SAEs and any failure of a product to meet the specifications in the NDA. The
holder  of  an  approved  NDA  must  also  submit  new  or  supplemental  applications  and  obtain  FDA  approval  for  certain  changes  to  the  approved  product,  product  labeling  or
manufacturing process. Advertising and promotional materials must comply with FDA rules and other applicable federal and state laws, and are subject to FDA review.

Drug product manufacturers and their facilities are subject to payment of user fees and continual review and periodic inspections by the FDA and other regulatory authorities
for  compliance  with  current  Good  Manufacturing  Practices  (“cGMP”),  and  adherence  to  commitments  made  in  the  NDA.  If  we  or  a  regulatory  agency  discover  previously
unknown problems with a product such as AEs or SAEs of unanticipated severity or frequency, or problems with the facility where the product is manufactured, a regulatory
agency  may  impose  restrictions  on  that  product  or  the  manufacturing  facility,  including  requiring  recall  or  withdrawal  of  the  product  from  the  market  or  suspension  of
manufacturing.

If we or our partners fail to comply with regulatory requirements following approval of our product candidates, a regulatory agency may:

●

●

●

●

●

●

●

issue a warning letter asserting we are in violation of the law;

seek an injunction or impose civil or criminal penalties or monetary fines;

suspend or withdraw regulatory approval;

suspend any ongoing clinical trials;

refuse to approve a pending NDA or supplements to an NDA submitted by us;

seize product; or

refuse to allow us to enter into supply contracts, including government contracts.

Our defense of any government investigation of alleged violations of law, or any lawsuit alleging such violations, could require us to expend significant time and resources in
response and could generate negative publicity. The occurrence of any event or penalty described above may prevent or inhibit our ability to commercialize our products and
generate revenues.

We  may  not  succeed  in  obtaining  or  maintaining  necessary  rights  to  drug  compounds  and  processes  for  our  development  pipeline  through  acquisitions  and  in-
licenses.

We  may  be  unable  to  acquire  or  in-license  any  compositions,  methods  of  use,  processes  or  other  third-party  intellectual  property  rights  from  third  parties  we  identify.  The
licensing and acquisition of third-party intellectual property rights is a competitive area, and more established companies are also pursuing strategies to license or acquire third-
party  intellectual  property  rights  we  may  consider  attractive.  These  established  companies  may  have  a  competitive  advantage  over  us  due  to  their  size,  cash  resources  and
greater clinical development and commercialization capabilities.

19

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property
rights on terms that would allow us to make an appropriate return on our investment. If we are unable to successfully obtain rights to required third-party intellectual property
rights, our business, financial condition and prospects for growth could suffer.

Because third parties without our knowledge may be developing competitive products, we may later learn that competitive products are superior which may cause to
terminate our research efforts of one or more product candidates.

We face potential completion from companies, particularly privately-held companies and foreign companies that may be developing competitive products that are superior to
one or more of our product candidates. If in the future we learn of the existence of one or more competitive products we may be required to:

●

●

●

cease our development efforts for a product candidate;

cause a partner to terminate its support of a product candidate; or

cause a potential partner to terminate discussions about a potential license.

Any of these events may occur after we have spent substantial sums in connection with the clinical research of one or more product candidates.

Compliance with governmental regulations regarding the treatment of animals used in research could increase our operating costs, which would adversely affect the
commercialization of our technology.

The Animal Welfare Act (“AWA”), is the United States federal law that covers the treatment of certain animals used in research. The AWA imposes a wide variety of specific
regulations  that  govern  the  humane  handling,  care,  treatment  and  transportation  of  certain  animals  by  producers  and  users  of  research  animals,  most  notably  relating  to
personnel, facilities, sanitation, cage size, feeding, watering and shipping conditions. Third parties with whom we contract are subject to registration, inspections and reporting
requirements. Some states have their own regulations, including general anti-cruelty legislation, which establish certain standards in handling animals. If we or our contractors
fail to comply with United States and foreign laws and regulations, as applicable, concerning the treatment of animals used in research, we may be subject to fines and penalties
and adverse publicity, and our operations could be adversely affected.

Public perception of ethical and social issues may limit or discourage the type of research we conduct.

Our clinical trials will involve people, and we and third parties with whom we contract also do research using animals. Governmental authorities could, for public health or other
purposes, limit the use of human or animal research or prohibit the use of our technology. In addition, animal rights activists could protest or make threats against our facilities,
which may cause property damage and delay our research. Ethical and  other  concerns  about  our  methods,  such  as  our  use  of  human  subjects  in  clinical  trials  or  our  use  of
animal testing, could adversely affect our market acceptance.

We  have  limited  experience  in  conducting  and  managing  the  preclinical  development  activities  and  clinical  trials  necessary  to  obtain  approvals  for  marketing  our
product candidates, including approval by the FDA.

Our efforts to develop our product candidates are at an early stage. To date, with one exception, we have not entered a compound into human clinical trials. We may be unable
to progress our other product candidates undergoing preclinical testing into clinical trials. Success in preclinical testing and early clinical trials does not ensure that later clinical
trials will succeed, and favorable initial results from a clinical trial do not determine outcomes in subsequent clinical trials. The indications of use for which we are pursuing
development may have clinical effectiveness endpoints not previously reviewed or validated by the FDA or foreign regulatory authorities, which may complicate or delay our
effort to obtain marketing approval. We cannot guarantee that our clinical trials will succeed. In fact, most compounds fail in clinical trials, even at companies far larger and
more experienced than us.

20

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We have not obtained marketing approval or commercialized any of our product candidates. We may not successfully design or implement clinical trials required for marketing
approval to market our product candidates. If we are unsuccessful in conducting and managing our preclinical development activities or clinical trials or obtaining marketing
approvals, we might not be able to commercialize our product candidates, or might be significantly delayed in doing so, which will materially harm our business.

RISKS RELATED TO OUR INTELLECTUAL PROPERTY

If we cannot obtain or protect intellectual property rights related to our future products and product candidates, we may not be able to compete effectively in our
markets.

We  rely  upon  a  combination  of  patents,  trade  secret  protection  and  confidentiality  agreements  to  protect  the  intellectual  property  related  to  our  future  products  and  product
candidates. The strength of patents in the biotechnology and pharmaceutical field involves complex legal and scientific questions and can be uncertain. The patent applications
we own or in-license may fail to result in patents with claims that cover the products in the United States or in other countries. There is no assurance that all of the potentially
relevant prior art relating to our patents and patent applications has been found; such prior art can invalidate a patent or prevent a patent from issuing based on a pending patent
application. Even if patents do successfully issue, third parties may challenge their validity, enforceability or scope, which may cause such patents to be narrowed or invalidated.
Even if unchallenged, our patents and patent applications may not adequately protect our intellectual property or prevent others from designing around our claims.

If the patent applications we hold or have in-licensed regarding our programs or product candidates fail to issue or if their breadth or strength of protection is threatened, it could
dissuade companies from collaborating with us to develop product candidates, and threaten our ability to commercialize products. Patents may not issue and issued patents may
be found invalid and unenforceable or challenged by third parties. Since patent applications in the United States and most other countries are confidential for a period after
filing, and some remain so until issued, we cannot be certain that we were the first to invent a patent application related to a product candidate. In certain situations, if we and
one or more third parties have filed patent applications in the United States and claiming the same subject matter, an administrative proceeding can be initiated to determine
which applicant is entitled to the patent on that subject matter. Patents have a limited lifespan. In the United States, the natural expiration of a patent is 20 years after it is filed,
although various extensions may be available. The life of a patent, and the protection it affords, is limited. Once the patent life has expired for a product, we may be open to
competition  from  generic  medications.  Further,  if  we  encounter  delays  in  regulatory  approvals,  the  time  during  which  we  could  market  a  product  candidate  under  patent
protection could be reduced.

21

 
 
 
 
 
 
 
Besides the protection afforded by patents, we rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is not patentable, processes for
which patents are difficult to enforce and any other elements of our drug discovery and development processes that involve proprietary know-how, information or technology
not  covered  by  patents.  Each  of  our  employees  agrees  to  assign  their  inventions  to  us  through  an  employee  inventions  agreement.  In  addition,  as  a  general  practice,  our
employees,  consultants,  advisors  and  any  third  parties  who  have  access  to  our  proprietary  know-how,  information  or  technology  enter  into  confidentiality  agreements.
Nonetheless, our trade secrets and other confidential proprietary information may be disclosed and competitors may otherwise gain access to our trade secrets or independently
develop substantially equivalent information and techniques. In addition, in January 2018 the FDA as part of its Transparency Initiative, launched a voluntary pilot program to
release clinical study reports summarizing clinical trial data. However, with only one company having disclosed information as part of the pilot program to date, the FDA in
response to concerns expressed by the academic community may consider making release of clinical study reports mandatory and may consider making additional information
publicly available on a routine basis, including information we may consider to be trade secrets or other proprietary information.

The laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws of the United States. We may encounter significant
problems  in  protecting  and  defending  our  intellectual  property  both  in  the  United  States  and  abroad.  If  we  are  unable  to  prevent  material  disclosure  of  the  non-patented
intellectual property related to our technologies to third parties, and there is no guarantee we will have any such enforceable trade secret protection, we may not be able to
establish or maintain a competitive advantage in our market, which could materially adversely affect our business, results of operations and financial condition.

Third-party intellectual property infringement claims may prevent or delay our development and commercialization efforts.

Our  commercial  success  depends  in  part  on  our  avoiding  infringement  on  the  patents  and  proprietary  rights  of  third  parties.  There  is  substantial  litigation,  both  within  and
outside  the  United  States,  involving  patent  and  other  intellectual  property  rights  in  the  biotechnology  and  pharmaceutical  industries,  including  patent  infringement  lawsuits,
interferences,  oppositions,  and  reexaminations  and  other  post-grant  proceedings  before  the  U.S.  Patent  and  Trademark  Office,  and  corresponding  foreign  patent  offices.
Numerous  U.S.  and  foreign  issued  patents  and  pending  patent  applications,  which  are  owned  by  third  parties,  exist  in  the  fields  in  which  we  and  our  partners  are  pursuing
product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidates may be subject to
claims of infringement of the patent rights of third parties.

Third  parties  may  assert  that  we  are  employing  their  proprietary  technology  without  authorization.  There  may  be  third-party  patents  or  patent  applications  with  claims  to
materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our product candidates. Because patent applications can take
many  years  to  issue,  there  may  be  patent  applications  currently  pending  that  may  later  result  in  patents  that  our  product  candidates  may  infringe.  Third  parties  may  obtain
patents in the future and claim that use of our technologies infringes on these patents. If any third-party patents were to be held by a court of competent jurisdiction to cover the
manufacturing process of any of our product candidates, any molecules formed during the manufacturing process or any final product itself, the holders of any such patents may
be able to block our ability to commercialize such product candidate unless we obtained a license under the applicable patents, or until such patents expire. Similarly, if any
third-party patents were to be held by a court of competent jurisdiction to cover aspects of our formulations, processes for manufacture or methods of use, including combination
therapy, the holders of any such patents may be able to block our ability to develop and commercialize the applicable product candidate unless we obtained a license or until
such patent expires. In either case, such a license may not be available on commercially reasonable terms or at all.

22

 
 
 
 
 
 
 
Parties making intellectual property claims against us may obtain injunctive or other equitable relief, which could block our ability to further develop and commercialize one or
more  of  our  product  candidates.  Defense  of  these  claims,  regardless  of  their  merit,  involves  substantial  litigation  expense  and  would  be  a  substantial  diversion  of  our
management’s attention from our business. If a claim of infringement against us succeeds, we may have to pay substantial damages, possibly including treble damages and
attorneys’ fees for willful infringement, pay royalties, redesign our infringing products or obtain one or more licenses from third parties, which may be impossible or require
substantial time and monetary expenditure.

We may need to obtain licenses to intellectual property rights from third parties.

We  may  need  to  obtain  licenses  from  third  parties  to  advance  our  research  or  allow  commercialization  of  our  product  candidates.  We  may  fail  to  obtain  these  licenses  at  a
reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize one or more of our product candidates, which could
harm  our  business  significantly.  We  cannot  provide  any  assurances  that  third-party  patents  do  not  exist  that  might  be  enforced  against  our  products,  resulting  in  either  an
injunction prohibiting our sales, or, with respect to our sales and other activities, an obligation on our part to pay royalties and/or other forms of compensation to third parties.
Because of the costs involved in defending patent litigation, we currently lack and may in the future lack the capital to defend our intellectual property rights.

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

Competitors may infringe our patents or the patents of our licensors. To counter such infringement or unauthorized use, we may be required to file infringement claims, or we
may be required to defend the validity or enforceability of such patents, which can be expensive and time-consuming. In an infringement proceeding, a court may decide that
either one or more of our patents or our licensors’ patents is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue because our
patents do not cover that technology. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted
narrowly and could put our patent applications at risk of not issuing.

Interference proceedings provoked by third parties or brought by us may be necessary to determine the priority of inventions regarding our patents or patent applications or
those of our partners or licensors. An unfavorable outcome could require us to cease using the related technology or to license rights to it from the prevailing party. Our business
could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Our defense of litigation or interference proceedings may fail and, even if
successful,  may  cause  us  to  incur  substantial  costs  and  distract  the  attention  of  our  management  and  other  employees.  We  may  not  be  able  to  prevent,  alone  or  with  our
licensors, misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the United States.

Because of the substantial amount of discovery required in intellectual property litigation, there is a risk that some of our confidential information could be compromised by
disclosure during this type of litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities
analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of our securities.

We may be subject to claims our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties.

We  employ  individuals  previously  employed  at  other  biotechnology  or  pharmaceutical  companies.  We  may  be  subject  to  claims  we  or  our  employees,  consultants  or
independent contractors have inadvertently or otherwise used or disclosed confidential information of our employees’ former employers or other third parties. We may also be
subject to claims that former employers or other third parties have an ownership interest in our patents. Litigation may be necessary to defend against these claims. There is no
guarantee of success in defending these claims, and if we succeed, litigation could cause substantial cost and be a distraction to our management and other employees.

23

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

The biotechnology and pharmaceutical industries are intensely competitive. We have competitors both in the United States and internationally, including major multinational
pharmaceutical companies, biotechnology companies and universities and other research institutions. Our competitors have substantially greater financial, technical and other
resources, such as larger research and development staff and experienced marketing and manufacturing organizations. Additional mergers and acquisitions in the biotechnology
and pharmaceutical industries may cause even more resources being concentrated in our competitors. Competition may increase further because of advances in the commercial
applicability of technologies and greater availability of capital for investment in these industries. Our competitors may develop, acquire or license drug products that are more
effective or less costly than any product candidate we may develop.

With  the  exception  of  one  product  candidate,  all  of  our  programs  are  in  a  preclinical  development  stage  and  are  targeted  toward  indications  for  which  there  are  approved
products  on  the  market  or  product  candidates  in  clinical  development.  We  will  face  competition  from  other  drugs  that  are  or  will  be  approved  for  the  same  therapeutic
indications. Our ability to compete successfully will depend largely on our ability to leverage our experience in drug discovery and development to:

●

●

●

●

●

discover and develop therapeutics superior to other products in the market;

attract qualified scientific, product development and commercial personnel;

obtain patent and/or other proprietary protection for our technology platform and product candidates;

obtain required regulatory approvals; and

successfully collaborate with pharmaceutical companies in the discovery, development and commercialization of new therapeutics.

The availability of our competitors’ products could limit the demand, and the price we can charge, for any products we may develop and commercialize. We will not achieve
our business plan if the acceptance of these products is inhibited by price competition or the reluctance of physicians to switch from existing drug products to our products, or if
physicians switch to other new drug products or reserve our products for use in limited circumstances. The inability to compete with existing or subsequently introduced drug
products would have a material adverse impact on our business, financial condition and prospects.

Established pharmaceutical companies may invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make our
product  candidates  less  competitive. Any  new  product  that  competes  with  an  approved  product  must  typically  demonstrate  advantages,  such  as  in  efficacy,  convenience,
tolerability  or  safety,  to  overcome  price  competition  and  to  succeed.  Our  competitors  may  obtain  patent  protection,  receive  approval  by  FDA  and/or  foreign  regulatory
authorities or discover, develop and commercialize product candidates before we do, which would have a material adverse impact on our business.

The  commercial  success  of  our  product  candidates  will  depend  upon  the  acceptance  of  these  product  candidates  by  the  medical  community,  including  physicians,
patients and healthcare payors.

Assuming  one  or  more  product  candidates  achieve  regulatory  approval  and  we  commence  marketing  such  products,  the  market  acceptance  of  any  product  candidates  will
depend on several factors, including:

●

●

demonstration of clinical safety and efficacy compared to other products;

the relative convenience, ease of administration and acceptance by physicians, patients and healthcare payors;

●

●

●

●

●

●

●

the prevalence and severity of any AEs or SAEs;

limitations or warnings in the label approved by FDA and/or foreign regulatory authorities for such products;

availability of alternative treatments;

pricing and cost-effectiveness;

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

our ability to obtain hospital formulary approval; and

our ability to obtain and maintain sufficient third-party payor coverage or reimbursement.

If our current product candidates are approved, we expect sales to generate substantially all of our product revenues for the foreseeable future, and as such, the failure of these
products to find market acceptance would harm our business.

If  insurance  and/or  government  coverage  and  adequate  reimbursement  are  not  available  for  our  product  candidates,  it  could  impair  our  ability  to  achieve  and
maintain profitability.

Market acceptance and sales of any product candidates we develop will depend on coverage and reimbursement policies of third-party payors. Government authorities and third-
party payors, such as private health insurers, hospitals and health maintenance organizations, decide which drugs they will pay for and establish reimbursement levels. Coverage
and adequate reimbursement may not be available for some or all of our product candidates. As patients generally rely on third-party payors to reimburse all or part of the costs
associated with their treatment, inadequate reimbursement amounts may reduce the demand for, or the price of, our future products. Thus, the availability of adequate coverage
and reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and commercial payors is critical to new product acceptance.

Obtaining coverage and reimbursement approval of a product from a government or other third-party payor is a time-consuming and costly process, and no uniform policy of
coverage and reimbursement for products exists among third-party payors in the United States. Even if we obtain coverage for a given product, the resulting reimbursement
payment rates might not be adequate for us to achieve or sustain profitability or may require co-payments that patients find unacceptable. If reimbursement is not available, or is
available at limited levels, we may not be able to successfully commercialize product candidates we develop.

Pricing pressures on our drug candidates, including as the result of proposed legislative changes, may negatively impact our future results of operations.

There  have  been  numerous  legislative  and  regulatory  proposals  to  change  the  healthcare  system  in  the  United  States  and  in  some  foreign  jurisdictions  that  could  affect  our
ability to sell products profitably. For example, in May 2018, the Trump administration issued a plan to lower drug prices, including among other things the disclosure of list
prices in television ads, increasing negotiated discounts in Medicare, banning pharmacy gag clauses, adopting real-time prescription benefit tools, and boosting low-cost generic
and  biosimilar  competition.  In  January  2019,  the  Trump  administration  proposed  a  rule  to  lower  prescription  drug  prices  and  out-of-pocket  costs  by  banning  rebates  on
prescription drugs paid by manufacturers to pharmacy benefit managers, Part D plans and Medicaid managed care organizations to increase the use and sales of their products.

Further, in February 2019, President Trump expressed concern that prescription drug prices in Canada are approximately 50% of prescription drug prices in the United States.
At the same time, all of the current Democratic Presidential candidates are advocating for a Medicare-for-all approach. While expanding Medicare would increase the demand
for prescription drugs, there is a likelihood that Medicare will be required to negotiate drug prices, which could adversely affect our future prospects.

At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control drug pricing, including price or patient
reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures. These proposed measures could reduce
the  ultimate  demand  for  our  products,  once  approved,  or  put  pressure  on  our  product  pricing.  The  availability  of  generic  treatments  may  also  substantially  increase  pricing
pressures on, and reduce reimbursement for, our future products. The potential application of user fees to generic drug products may expedite approval of additional generic
drug treatments. We expect to experience additional pricing pressures in connection with sale of any of our products, due to the trend toward managed healthcare, the increasing
influence of health maintenance organizations and additional legislative changes.

In some non-U.S. jurisdictions, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely
from country to country. The European Union, or EU, provides options for its member states to restrict the range of medicinal products for which their national health insurance
systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may
instead adopt a system of direct or indirect controls on the profitability of the Company placing the medicinal product on the market. There can be no assurance that any country
that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for our products. Historically,
products launched in the EU do not follow price structures of the U.S. and tend to be priced significantly lower.

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

We do not have an organization for the sales, marketing and distribution of pharmaceutical products and the cost of establishing and maintaining such an organization may
exceed the cost-effectiveness of doing so. To market any products that may be approved, we must build our sales, marketing, managerial and other non-technical capabilities or
arrange with third parties to perform these services.

Our current and future partners may not dedicate sufficient resources to the commercialization of our product candidates or may otherwise fail in their commercialization due to
factors beyond our control. If we are unable to establish effective alliances to enable the sale of our product candidates to healthcare professionals and in geographical regions,
including the United States, that will not be covered by our own marketing and sales force, or if our potential future strategic partners do not successfully commercialize the
product candidates, our ability to generate revenues from product sales will be adversely affected.

If  we  are  unable  to  establish  adequate  sales,  marketing  and  distribution  capabilities,  whether  independently  or  with  third  parties,  we  may  not  be  able  to  generate  sufficient
product revenue and may not become profitable. We will be competing with many companies that have extensive and well-funded marketing and sales operations. Without an
internal team or the support of a third-party to perform marketing and sales functions, we may be unable to compete successfully against these more established companies.

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

If any of our product candidates are approved for commercialization, we may enter into agreements with third parties to market them on a worldwide basis or in more limited
geographical regions. We expect we will be subject to additional risks related to entering into international business relationships, including:

●

●

●

●

different regulatory requirements for drug approvals in foreign countries;

reduced protection for intellectual property rights;

unexpected changes in tariffs, trade barriers and regulatory requirements;

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

●

●

●

●

●

●

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

foreign taxes, including withholding of payroll taxes;

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

workforce uncertainty in countries where labor unrest is endemic;

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

business interruptions  resulting  from  geopolitical  actions,  including  war  and  terrorism,  or  natural  disasters  including  earthquakes, typhoons,  floods  and
fires.

RISKS RELATED TO OUR BUSINESS OPERATIONS AND INDUSTRY

If  we  lose  key  management  or  scientific  personnel,  cannot  recruit  qualified  employees,  directors,  officers,  or  other  personnel  or  experience  increases  in  our
compensation costs, our business may materially suffer.

We  depend  on  principal  members  of  our  executive  and  research  teams;  the  loss  of  whose  services  may  adversely  impact  the  achievement  of  our  objectives.  We  are  highly
dependent on our Chairman of the Board and Chief Executive Officer, Dr. Gary Wilcox, and our President, Dr. Sam Lee. We do not carry “key-man” life insurance on any of
our employees or advisors. Furthermore, our future success will also depend in part on the continued service of our key scientific and management personnel and our ability to
identify,  hire,  and  retain  additional  personnel.  We  may  not  be  able  to  attract  and  retain  personnel  on  acceptable  terms,  as  there  is  significant  competition  among  numerous
pharmaceutical companies for individuals with similar skill sets. Because of this competition, our compensation costs may increase significantly. If we lose key employees, our
business may suffer.

If we expand our organization, we may experience difficulties in managing growth, which could disrupt our operations.

As of April 1, 2019, we have 10 full-time employees. As our company matures, we expect to expand our employee base to increase our managerial, scientific and operational,
commercial, financial and other resources and to hire more consultants and contractors. Future growth would impose significant additional responsibilities on our management,
including  the  need  to  identify,  recruit,  maintain,  motivate  and  integrate  additional  employees,  consultants  and  contractors.  Also,  our  management  may  need  to  divert  a
disproportionate amount of its attention away from our day-to-day activities and to managing these growth activities. We may not be able to effectively manage the expansion
of  our  operations,  which  may  cause  weaknesses  in  our  infrastructure,  and  give  rise  to  operational  mistakes,  loss  of  business  opportunities,  loss  of  employees  and  reduced
productivity among remaining employees. Our expected growth could require significant capital expenditures and may divert financial resources from other projects, such as
developing additional product candidates. If our management cannot effectively manage our growth, our expenses may increase more than expected, our ability to generate
and/or grow revenues could be reduced, and we may not be able to implement our business strategy. Our future financial performance and our ability to commercialize product
candidates and compete effectively will depend, in part, on our ability to manage our future growth.

Any relationships with customers and third-party payors may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws
and  health  information  privacy  and  security  laws.  If  we  are  unable  to  comply,  or  have  not  fully  complied,  with  such  laws,  we  could  face  criminal  sanctions,  civil
penalties, contractual damages, reputational harm and diminished profits and future earnings.

If we obtain FDA approval for any of our product candidates and commercialize those products in the United States, our operations may be directly, or indirectly through our
customers, subject to various federal and state fraud and abuse laws, including, without limitation, the federal Anti-Kickback Statute and the federal False Claims Act. These
laws may impact, among other things, our proposed sales, marketing and education programs. We may be subject to patient privacy regulation by the federal government and
by the U.S. states and foreign jurisdictions in which we conduct our business. The laws that may affect our ability to operate include:

●

the federal Anti-Kickback  Statute,  which  prohibits,  among  other  things,  persons  from  knowingly  and  willfully  soliciting,  receiving, offering  or  paying
remuneration, directly or indirectly, to induce, or in return for, either the referral of an individual,  or the purchase or recommendation of an item or service
for which payment may be made under a federal healthcare program, such as the Medicare and Medicaid programs;

27

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
●

●

●

●

federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, individuals or entities from knowingly
presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payers that are false or fraudulent;

the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created new federal criminal statutes  that prohibit executing a
scheme to defraud any healthcare benefit program and making false statements relating to healthcare matters;

HIPAA, as amended by the Health Information Technology and Clinical Health Act of 2009, or HITECH, and its implementing regulations, which imposes
certain requirements relating to the privacy, security and transmission of individually identifiable health information; and

state and  foreign  law  equivalents  of  each  of  the  above  federal  laws,  such  as  anti-kickback  and  false  claims  laws  which  may  apply to  items  or  services
reimbursed by any third-party payer, including commercial insurers, and state and foreign laws governing  the privacy and security of health information in
certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

If our operations are found to violate any of the laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including, without
limitation,  civil  and  criminal  penalties,  damages,  fines,  possible  exclusion  from  Medicare,  Medicaid  and  other  government  healthcare  programs,  and  curtailment  or
restructuring of our operations, which could adversely affect our ability to operate our business and our results of operations.

We face potential product liability, and, if successful claims are brought against us, we may incur substantial liability and costs.

Using our product candidates in clinical trials and the sale of any products for which we obtain marketing approval exposes us to the risk of product liability claims. Product
liability claims might be brought against us by consumers, healthcare providers, pharmaceutical companies or others selling or otherwise coming into contact with our products.
If we cannot successfully defend against product liability claims, we could incur substantial liability and costs. Regardless of merit or eventual outcome, product liability claims
may cause:

●

●

●

●

●

●

●

impairment of our business reputation;

withdrawal of clinical trial participants;

costs due to related litigation;

distraction of management’s attention from our primary business;

substantial monetary awards to patients or other claimants;

the inability to commercialize our product candidates; and

decreased demand for our product candidates, if approved for commercial sale.

Insurance  coverage  is  becoming  increasingly  expensive  and  we  may  not  be  able  to  maintain  insurance  coverage  at  a  reasonable  cost  or  in  sufficient  amounts  to  protect  us
against losses due to liability. If and when we obtain marketing approval for product candidates, we intend to expand our insurance coverage to include the sale of commercial
products; however, we may be unable to obtain product liability insurance on commercially reasonable terms or in adequate amounts. Occasionally, large judgments have been
awarded in class action lawsuits based on drugs that had unanticipated adverse effects. A successful product liability claim or series of claims brought against us could cause
our stock price to decline and, if judgments exceed our insurance coverage, could adversely affect our results of operations and business.

Business interruptions resulting from natural disasters and adverse weather events could cause delays in research and development of our product candidates.

Our principal offices are in Bothell, Washington where we conduct our scientific research. We also maintain a small finance and accounting office in Miami, Florida. We are
vulnerable to natural disasters such as earthquakes and tornados as well as other events that could disrupt our operations and cause delays in research and development of our
product candidates. We do not carry insurance for natural disasters and we may not carry sufficient business interruption insurance to compensate us for losses that may occur.
Any losses or damages we incur could have a material adverse effect on our operations.

If  our  information  technology  systems  are  compromised,  the  information  we  store  and  process,  including  our  intellectual  property,  could  be  accessed,  publicly
disclosed, lost or stolen, which could harm our business, relationships with strategic partners and future results of operations.

Companies  are  increasingly  suffering  damage  from  attacks  by  hackers.  In  the  ordinary  course  of  business,  we  store  sensitive  information,  such  as  our  intellectual  property,
including trade secrets and results of our clinical and preclinical research, and that of our suppliers and business partners, on a central server, and such information is transmitted
via email correspondence. The secure maintenance and processing of this information is critical to our research and development activities and future operations. Despite our
security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breaches due to employee error, malfeasance or other disruptions.
Any such breach could compromise our information technology systems and the information stored there could be accessed by third parties, publicly disclosed, lost or stolen.
Any such access, disclosure, misappropriation or other loss of information could result in disruption of our operations, including our existing and future research collaborations,
and damage our reputation, which in its turn could harm our business and future results of operations.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material
adverse effect on our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment
and disposal of hazardous materials and wastes. Our operations involve using hazardous and flammable materials, including chemicals and biological materials. Our operations
also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or
injury from these materials. If contamination occurs or injury results from our use of hazardous materials, we could be held liable for any resulting damages, and any liability
could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties.

Although our workers’ compensation insurance may cover us for costs and expenses, we may incur additional costs due to injuries to our employees resulting from the use of
hazardous materials or other work-related injuries, and this insurance may not provide adequate coverage against other potential liabilities. We may incur substantial costs to
comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our research, development or
production efforts. Failure to comply with these laws and regulations also may cause substantial fines, penalties or other sanctions.

RISKS RELATED TO OUR COMMON STOCK

Due to factors beyond our control, our common stock price may be volatile, or may decline regardless of our operating performance, and you may not be able to resell
your shares.

The market price of our common stock will depend on a number of factors, many of which are beyond our control and may not be related to our operating performance. These
fluctuations could cause you to lose all or part of your investment in our common stock since you might be unable to sell your shares at or above the price you paid. Factors that
could cause fluctuations in the market price of our common stock include the following:

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

price and volume fluctuations in the overall stock market from time to time;

volatility in the market prices and trading volumes of biotechnology stocks generally, or those in our peer group in particular;

our announcements concerning the initiation and results of clinical trials;

changes in operating performance and stock market valuations of other biotechnology companies generally, or those in our industry in particular;

sales of shares of our stock by us or our stockholders;

the failure of securities analysts to maintain coverage of us, changes in financial estimates by securities analysts who follow our company or our failure to meet
these estimates or the expectations of investors;

the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;

announcements by us or our competitors of new novel medicines;

the public’s reaction to our earnings releases, other public announcements and filings with the SEC;

rumors and market speculation involving us or other companies in our industry;

actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;

actual or anticipated changes in our operating results or fluctuations in our operating results;

litigation involving us, our current or former officers and directors, our stockholders, our industry, or investigations by regulators  into our operations or those of our
competitors;

developments or disputes concerning our intellectual property or other proprietary rights;

new laws or regulations or new interpretations of existing laws or regulations applicable to our business;

changes in accounting standards, policies, guidelines, interpretations or principles;

any significant change in our management; and

general economic conditions and slow or negative growth in any of our significant markets.

In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often
been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

Any future impairment in the carrying value of goodwill and in-process research and development assets could depress our stock price.

Historically, we had a significant amount of goodwill and indefinite-lived intangible assets for in-process research and development (“IPR&D”) on our balance sheet. Goodwill
and indefinite-lived intangible assets must be evaluated for impairment annually or more frequently if events indicate it is warranted. If the carrying value of a reporting unit or
IPR&D  asset  exceeds  its  current  fair  value,  the  goodwill  or  IPR&D  asset  is  considered  impaired.  Events  and  conditions  that  could  result  in  impairment  in  the  value  of  our
indefinite-lived  assets  and  goodwill  include,  but  are  not  limited  to,  significant  negative  industry  or  economic  trends,  significant  decline  in  the  Company’s  stock  price  for  a
sustained period of time, significant decline in market capitalization relative to net book value, limited funding that could delay development efforts, significant changes in the
manner  of  use  of  the  assets  or  the  strategy  for  the  Company’s  overall  business,  safety  or  efficacy  issues  that  surface  during  development  efforts,  or  preclinical  and  clinical
outcomes that reduce the probability for technical and regulatory success of our product candidates.

We have incurred impairment charges of approximately $131,061,000 from our IPR&D prior to and as of December 31, 2017; refer to “Item 7 – Management’s Discussion and
Analysis – Critical Accounting Policies and Estimates – Business Combinations and Intangible Assets.” As of December 31, 2018, we incurred an additional $53,905,000 in
non-cash impairment charges which was a full write-off of the remaining IPR&D and we no longer have an IPR&D asset.

We may in the future be required to record impairment charges to write-off goodwill which is also related to our merger with RFS Pharma in 2014. Our stock price could be
negatively impacted should future impairments of our goodwill occur.

At December 31, 2018 and 2017, the Company had goodwill of $65,195,000 and determined the fair value of its reporting unit, measured by the Company’s Nasdaq market
capitalization and an income approach analysis, exceeded the carrying value at December 31, 2018; therefore, management did not consider goodwill to be impaired.

Because  certain  of  our  stockholders  control  a  significant  number  of  shares  of  our  common  stock,  they  may  have  effective  control  over  our  actions  requiring
stockholder approval.

As of March 28, 2019, our directors, executive officers and principal stockholders (those beneficially owning in excess of 5%), and their respective affiliates, beneficially own
approximately  48%  of  our  outstanding  shares  of  common  stock. As  a  result,  these  stockholders,  acting  together,  would  have  the  ability  to  control  the  outcome  of  matters
submitted to our stockholders for approval, including the election of directors and any merger, consolidation or sale of all or substantially all of our assets.

Dr. Raymond Schinazi, our former Board Chairman, and Dr. Philip Frost, a director and certain other stockholders entered into a Stockholders Rights Agreement in November
2014  when  we  acquired  another  company  headed  by  Dr.  Schinazi.  This Agreement  gives  each  of  Dr.  Schinazi  and  Dr.  Frost  (and  certain  other  stockholders)  the  right  to
designate three directors to a seven-person board of directors and together agree upon the seventh designee. In addition, our principal stockholders, acting together, would have
the ability to control the management and affairs of our company. Accordingly, this concentration of ownership might harm the market price of our common stock by:

●

●

●

delaying, deferring or preventing a change in corporate control;

impeding a merger, consolidation, takeover or other business combination involving us; or

discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us.

Further,  the  Stockholder  Rights Agreement  provides  Dr.  Schinazi  and  Dr.  Frost  and  certain  other  Company  stockholders  with  rights  including  the  right  to  approve  future
financings and a right of first refusal, which have not been impediments to date. However, in the event of any future disagreements between Dr. Schinazi and Dr. Frost, we may
be unable to raise future capital we need or make concessions to one of these directors, which may adversely affect us or result in added expenses.

31

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Future sales and issuances of our common stock or rights to purchase common stock, including under our equity incentive plan, could cause additional dilution of the
percentage ownership of our stockholders and could cause our stock price to fall.

We  expect  that  significant  additional  capital  will  be  needed  to  continue  our  planned  operations.  To  the  extent  we  raise  additional  capital  by  issuing  equity  securities,  our
stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a
manner we determine from time to time. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors may be materially
diluted  by  subsequent  sales.  These  sales  may  also  result  in  material  dilution  to  our  existing  stockholders,  and  new  investors  could  gain  rights  superior  to  our  existing
stockholders.

Under  our  Equity  Incentive  Plans,  our  management  may  grant  stock  options  and  other  equity-based  awards  to  our  employees,  directors  and  consultants.  Approximately
2,467,000 million shares of common stock are available for future grant.

We are currently involved in a class action lawsuit, a related derivative action, and other litigation, and may in the future  be  involved  in  other  legal  proceedings,
which may be expensive and time consuming to defend, and, if resolved adversely, could harm our business and financial condition.

We and certain current and former executive officers and directors of the Company are currently defendants in a class action lawsuit filed with the U.S. District Court for the
District of New Jersey alleging violation of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder, and a related derivative action lawsuit filed with the
U.S. District Court for the Western District of Washington, and may become involved in additional legal proceedings in the future. See “Item 3 – Legal Proceedings” for more
information. Similar allegations are also asserted in a lawsuit filed with the U.S. District Court for the District of Minnesota by a former Biozone Pharmaceuticals, Inc. lawyer,
and currently on appeal with the U.S. Court of Appeals for the Eighth Circuit. These proceedings can be time consuming, divert management’s attention and resources and
cause  us  to  incur  significant  expenses.  While  we  believe  we  have  insurance  coverage  for  the  class  action  suit  and  the  derivative  action,  our  insurance  carrier  has  initially
declined to cover the lawsuits. While we are seeking to reverse this decision, even if we can do so the amount of insurance may be insufficient. Furthermore, because litigation
is inherently unpredictable, the results of any such actions may have a material adverse effect on our business, and financial condition, and cause our stock price to decrease.

Failure to meet the continued listing requirements of The Nasdaq Capital Market, could result in delisting of our common stock, which in its turn would negatively
affect the price of our common stock and limit investors’ ability to trade in our common stock.

Our  common  stock  trades  on  The  Nasdaq  Capital  Market  (“Nasdaq”).  Nasdaq  rules  impose  certain  continued  listing  requirements,  including  the  minimum  $1  bid  price,
corporate governance standards and number of public stockholders. If we fail to meet these continued listing requirements, Nasdaq may take steps to delist our common stock.
If our common stock is delisted from The Nasdaq Capital Market, we could face significant material adverse consequences, including:

●

●

●

●

●

a limited availability of market quotations for our common stock;

reduced liquidity with respect to our common stock;

a determination that our shares of common stock are a “penny stock” which will require broker-dealers trading in our common stock to adhere to more stringent
rules, possibly resulting in a reduced level of trading activity in the secondary trading market for our common stock;

a limited amount of news and analyst coverage for our company; and

a limited ability to issue additional securities or obtain additional financing in the future.

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

Under Section 382 of the Internal Revenue Code of 1986 if a corporation undergoes an “ownership change,” 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 net operating loss carry forwards (“NOLs”), and other pre-change tax attributes (such as
research tax credits) to offset its post-change income may be limited. We believe that, with the RFS Pharma and Discovery mergers and other transactions that have occurred
over the past three years, we may have triggered an “ownership change” limitation. We may also experience ownership changes in the future because of subsequent shifts in our
stock ownership. If we earn net taxable income, our ability to use our pre-change net operating loss carry forwards to offset U.S. federal taxable income may be subject to
limitations, which could result in increased future tax liability to us. 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.

Because our common stock is not actively traded, purchasers of our stock may incur difficulty in selling their shares at or above the price they paid for them, or at
all.

Our average daily trading volume on The Nasdaq Capital Market has been approximately 35,400 shares of common stock for the 60 trading days prior to March 28, 2019. An
active  market  for  our  common  stock  may  never  develop,  or  if  it  does,  it  may  not  be  sustained. Accordingly,  investors  may  experience  difficulty  is  selling  their  shares  of
common stock at or above the price they paid for them, or at all.

We do not intend to pay dividends on our common stock so any returns will be limited to the value of our stock.

We have never declared or paid any cash dividends on our common stock. We anticipate we will retain future earnings for the development, operation and expansion of our
business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to stockholders will therefore be limited to the appreciation of their
stock.

Because we may not attract the attention of major brokerage firms, it could have a material impact upon the price of our common stock.

It is possible that securities analysts of major brokerage firms will not provide research coverage for our common stock. The absence of such coverage limits the likelihood that
an active market will develop for our common stock. It may also make it more difficult for us to attract new investors when we acquire additional capital.

Future sales of our common stock could cause the market price for our common stock to decline, even if our business is performing well.

As of March 28, 2019, we had approximately 31,620,646 million shares of common stock outstanding, approximately 15 million of which are either free trading or may be sold
without volume or manner of sale limitations under Rule 144. The remainder of our shares, because they are held by affiliates, are subject to additional restrictions as described
below.

In general, Rule 144 provides that any person who is not an affiliate of the Company and has not been an affiliate for 90 days, and who has held restricted common stock for at
least six months, is entitled to sell their restricted stock freely, provided that we stay current in our SEC filings. After one year, a non-affiliate may sell without any restrictions.

Our largest stockholder, Dr. Raymond Schinazi, who beneficially owned 32% of our common stock as of March 29, 2019, resigned as our Board Chairman effective February
1, 2019. However, a Stockholder Rights Agreement he signed in 2014, in which another principal shareholder is a party, requires that we continue to treat him as an affiliate.

The shares of common stock outstanding which are held by affiliates of the Company are subject to additional restrictions. An affiliate may sell after a six-month holding period
with the following restrictions:

(i) we are current in our filings;

(ii) certain manner of sale provisions; and

(iii) filing of Form 144.

Future  sales  of  substantial  amounts  of  shares  of  our  common  stock  in  the  public  market,  or  the  perception  that  those  sales  will  occur,  could  cause  the  market  price  of  our
common stock to decline significantly, even if our business is performing well.

We may issue preferred stock which could make it more difficult for a third-party to acquire us and could depress our stock price.

In accordance with the provisions of our Certificate of Incorporation and the Stockholder Rights Agreement described above, our Board may issue one or more additional series
of preferred stock that have more than one vote per share, so long as the Board obtains the majority approval of each of the groups of stockholders who formerly held our
Series A  and  Series  B.  This  could  permit  our  Board  to  issue  preferred  stock  to  investors  who  support  our  management  and  give  effective  control  of  our  business  to  our
management. Issuance of preferred stock could block an acquisition resulting in both a drop in our stock price and a decline in interest of our common stock. This could make it
more difficult for stockholders to sell their common stock. This could also cause the market price of our common stock shares to drop significantly, even if our business is
performing well.

We continue to have material weaknesses in our internal control over financial reporting. If we are unable to remediate these, or if we experience additional material
weaknesses in the future or otherwise fail to maintain effective internal controls, we may not be able to accurately or timely report our financial condition or results
of operations, which may adversely affect investor confidence in us and could negatively impact our ability to raise capital.

Our  management  has  concluded  that,  as  of  December  31,  2018,  our  internal  control  over  financial  reporting  was  not  effective.  Management  has  identified  two  material
weaknesses in our internal control over financial reporting related to the following:

(i) management’s failure  to  maintain  an  effective  financial  reporting  process  to  ensure  there  were  timely and  documented  reviews  over  completeness  and  accuracy  of

information included in the financial statements; and

(ii) management’s failure to design and maintain controls over management’s review of technical accounting matters and account reconciliations.

See “Part II – Item 9A – Controls and Procedures” for more information. Although we have developed and are implementing a plan to remediate these material weaknesses, and
expect  to  focus  on  remediating  these  material  weaknesses  in  2019,  we  may  not  be  able  to  remediate  all  or  any  of  them  in  the  near  future.  Furthermore,  additional  material
weaknesses  in  our  internal  control  over  financial  reporting  may  be  identified  in  the  future.  Material  weaknesses  identified  by  management  could  result  in  a  material
misstatement  in  our  annual  or  interim  financial  statements  that  would  not  be  prevented  or  detected.  If  we  are  unable  to  remediate  the  identified  material  weaknesses  or
implement required new or improved controls, our ability to record, process and report financial information accurately, and to prepare financial statements within the time
periods specified by the rules and forms of the SEC could be adversely affected. The occurrence of or failure to remediate the material weaknesses may adversely affect investor
confidence in us and could negatively impact our ability to raise capital.

Recently  the  SEC  sued  four  public  companies  alleging  in  part  that  they  had  violated  Section  13(b)  of  the  Exchange Act  resulting  from  their  failure  to  remediate
material weaknesses in their internal control over financial reporting over an extensive period of time. Three of these companies had remediated their material weaknesses at the
time the lawsuits were filed. Since we acquired Cocrystal Discovery, Inc., our principal subsidiary, in January 2014, we have identified and disclosed material weaknesses in
internal control over financial reporting beginning with the year ended December 31, 2014 and have since made significant progress in remediating them. As of December 31,
2018, we had two material weaknesses, both of which had previously been identified as of December 31, 2017 and have not been remediated. See “Part II – Item 9a Controls
and  Procedures”  for  more  information.  If  the  SEC  Staff  investigates  us  and  following  that  investigation  a  lawsuit  is  filed  alleging  that  we  had  not  remediated  our  material
weaknesses for a number of consecutive annual reporting periods, we will face the following risks:

●

It will divert our management’s attention from our core business of drug development;

● We will incur substantial legal fees in connection with both the investigation and the lawsuit if it is filed;

●

If we are sued, we may be required to pay a civil monetary penalty in addition to other remedies the SEC or a court may impose;

● Any public disclosure may cause investors to sell our stock which may result in a material decline in our stock price that will cause investors to lose money; and

● Our existing stockholders will experience more dilution as we are required to raise capital at a lower price per share.

 Item 1B. Unresolved Staff Comments

None.

 Item 2. Properties

We have operating facilities in Bothell, Washington and Miami, Florida.

We  lease  approximately  9,400  square  feet  of  office  and  laboratory  space  in  Bothell,  Washington.  In  June  2018,  we  signed  an  amendment  to  the  Bothell,  Washington  lease
agreement to extend the term through January 2024.

On September 1, 2018, the Company relocated its accounting and finance offices from Tucker, Georgia to Miami, Florida, where it leases a total of 1,280 square feet of office
space. In connection with the relocation, the Company entered into a lease agreement with a limited liability company controlled by Dr. Phillip Frost, a director and a principal
stockholder  of  the  Company.  The  lease  term  is  three  years  with  an  optional  three-year  extension.  Following  the  relocation,  the  Company  closed  down  its  office  in  Tucker,
Georgia  and  terminated  the  respective  month-to-month  lease  agreement  with  the  limited  liability  company  owned  by  our  former  Chairman  and  a  principal  stockholder,  Dr.
Raymond Schinazi.

 Item 3. Legal Proceedings

From  time  to  time,  the  Company  is  a  party  to,  or  otherwise  involved  in,  legal  proceedings  arising  in  the  normal  course  of  business. As  of  the  date  of  this  report,  except  as
described below, the Company is not aware of any proceedings, threatened or pending, against it which, if determined adversely, would have a material effect on its business,
results of operations, cash flows or financial position.

On September 20, 2018, Anthony Pepe, individually and on behalf of a class, filed with the United States District Court for the District of New Jersey a complaint against the
Company, certain current and former executive officers and directors of the Company and the other defendants named therein for violation of Section 10(b) of the Exchange Act
and Rule 10b-5 promulgated thereunder. The class consists of the persons and entities who purchased the Company’s common stock during the period from September 23, 2013
through September 7, 2018. Pepe also alleges violation of other sections of the Exchange Act by the defendants named in the complaint other than the Company. Pepe seeks
damages, pre-judgment and post-judgment interest, reasonable attorneys’ fees, expert fees and other costs.

On January 16, 2019, Ms. Susan Church, a stockholder of the Company, filed with the United States District Court for the Western District of Washington a derivative suit
against  certain  current  and  former  executive  officers  and  directors  of  the  Company  alleging  breach  of  fiduciary  duties,  unjust  enrichment,  waste  of  corporate  assets,  and
violations of the rules governing proxy solicitation. Church seeks, among other things, money damages, disgorgement of profits from alleged wrongful conduct, including cash
bonuses, pre-judgment and post-judgment interest, reasonable attorneys’ fees, expert fees and other costs.

On September 7, 2018, the SEC filed with the United States District Court for the Southern District of New York a complaint against Dr. Philip Frost, a director and principal
stockholder of the Company, a trust Dr. Frost controls and OPKO Health, Inc., a stockholder of the Company, of which Dr. Frost is the Chief Executive Officer, as well as other
defendants  named  therein.  On  January  10,  2019,  the  District  Court  entered  final  judgments  against  these  defendants  on  their  consent  without  admitting  or  denying  the
allegations set forth in the complaint. Dr. Frost was permanently enjoined from violating a certain anti-fraud provision of the Securities Act of 1933, future violations of Section
13(d) of the Exchange Act and Rule 13d-1(a) thereunder, and participating in penny stock offerings subject to certain exceptions.

November  2017,  Lee  Pederson,  a  former  Biozone  lawyer,  filed  a  lawsuit  in  Minnesota  against  co-defendants  the  Company,  Dr.  Phillip  Frost,  OPKO  Heath,  Inc.  and  Brian
Keller for various allegations. On September 13, 2018, the United States District Court granted the Company and its co-defendants’ motion to dismiss Pederson’s amended
complaint. Subsequent to September 30, 2018, Pederson has filed a notice of appeal with the United States Court of Appeals for the Eighth Circuit on October 11, 2018.

While  the  Company  intends  to  defend  itself  vigorously  from  the  claims  in  the  aforementioned  disputes,  it  is  unable  to  predict  the  outcome  of  these  legal  proceedings. Any
potential loss as a result of these legal proceedings cannot be reasonably estimated. As a result, the Company has not recorded a loss contingency for any of the aforementioned
claims.

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

The following discussion and analysis should be read in conjunction with the Consolidated Financial Statements included elsewhere in this report.

Company Overview

Our primary business going forward is to develop novel medicines for use in the treatment of human viral diseases. Discovery has been developing novel technologies and
approaches to create first-in-class and best-in-class antiviral drug candidates since its initial funding in 2008. Our focus is to pursue the development and commercialization of
broad-spectrum antiviral drug candidates that will transform the treatment and prophylaxis of viral diseases in humans. By concentrating our research and development efforts
on viral replication inhibitors, we plan to leverage our infrastructure and expertise in these areas.

During fiscal year ended December 31, 2018, the following key aspects of our business advanced:

● We signed exclusive license and collaboration agreement with Merck and Co., Inc. to discover and develop certain proprietary influenza A/B antiviral agents.
● We secured a total of $17 million gross proceeds over the past 12 months; $4 million from upfront payment from Merck and $13 million gross proceeds from common-

stock only financings.

● We reported encouraging safety and preliminary efficacy data for its U.S. Phase 2a study evaluating CC-31244 for the ultra-short treatment of HCV infected individuals
showing  no  drug-drug  interactions  and  substantial  efficacy.  The  data  obtained  from  this  trial  used  2  weeks of CC-31244 in combination with Epclusa followed by 4
weeks of Epclusa alone.

● We signed  Clinical  Trial Agreement for investigator-initiated Phase 2a study in Hong Kong of CC-31244 in a novel combination therapy for ultra-short treatment  of

HepC.

37

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● We received FDA clearance to initiate Phase 2a clinical study evaluating CC-31244 for the treatment HepC virus.
● We presented preclinical characterization data of CC-42344 at the 6th ISIRV-AVG Conference demonstrating excellent antiviral activity against influenza A strains and

favorable pharmacokinetic and safety profile.

● We successfully completed up-listing on the Nasdaq Capital Market.

Results of Operations

As stated above, we are focused on research and development of novel medicines for use in the treatment of human viral diseases. Accordingly, we had no revenue for the years
ended December 31, 2018 or 2017. For the year ended December 31, 2018, we had a net loss of $49,048,000 compared to a net loss of $613,000 for 2017. This net loss for the
year  was  due  to  losses  from  ongoing  operations,  offset  by  income  tax  benefits.  The  2018  loss  was  significantly  higher  due  to  an  impairment  charge  of  $53,905,000  on  our
IPR&D  asset  offset  by  a  $13,582,000  deferred  tax  benefit  associated  with  the  impairment  charge  incurred.  Our  operating  loss  for  the  year  ended  December  31,  2018  was
$62,924,000 compared to an operating loss of $8,262,000 in 2017. The operating loss for 2018 included the impairment charge of $53,905,000 on our IPR&D asset noted above.
Other  income  was  $294,000  for  the  year  ended  December  31,  2018,  which  is  primarily  due  to  a  $306,000  gain  on  the  fair  value  of  derivative  liabilities.  Under  accounting
principles generally accepted in the United States, we record other income or expense for the change in fair value of our outstanding warrants that are accounted for as liabilities
during each reporting period. If the value of the warrants decreases during a period, which occurred during the year ended December 31, 2018, we record other income. The fair
value of our outstanding warrants is inversely related to the fair value of the underlying common stock; as such, a decrease in the fair value of our common stock during a given
period generally results in other income while an increase in the fair value of our common stock generally results in other expense. This other income or expense is non-cash.
We believe investors should focus on our operating loss rather than net income or loss for the periods presented.

Research and Development Expense

Research and development expenses consist primarily of compensation-related costs for our 8 employees dedicated to research and development activities and for our Scientific
Advisory Board members, as well as lab supplies, lab services, and facilities and equipment costs. We expect research and development expenses to increase in future periods as
we expand our pre-clinical development activities. Also included in research and development expense for the year ended December 31, 2018 is an impairment charge related to
our in-process research and development (IPR&D) intangible asset in the amount of $53,905,000, which were acquired through our November 2014 merger with RFS Pharma.
We  decided  to  move  forward  our  HCV  program  solely  with  CC-31244  compound  and  abandoned  the  compounds  associated  with  the  IPR&D  intangible  asset,  which  were
licensed to RFS Pharma by Emory.

Total research and development expenses were $58,572,000 for the year ended December 31, 2018, compared with $5,822,000 for the year ended December 31, 2017. This
increase of $52,750,000 is primarily the result of recognizing an impairment loss on IPR&D of $53,905,000 in 2018. Excluding the impact of the IPR&D impairment charge,
research and development expenses were $4,667,000, and therefore decreased $1,155,000, for the year ended December 31, 2018. This year over year decrease in research and
development expenditures was primarily due to decreased employee compensation costs after closing our Tucker, Georgia lab facility in the fourth quarter of 2017. We expect
research and development expenses to decrease in 2019 with the completion of the Phase 2a study in the United States.

Additionally, the planned Hong Kong study research costs will be paid by the investigator and there is limited research remaining from our 2018 United States Phase 2a trial.

General and Administrative Expense

General  and  administrative  expense  includes  compensation-related  costs  for  our  employees  dedicated  to  general  and  administrative  activities,  legal  fees,  audit  and  tax  fees,
consultants and professional services, and general corporate expenses.

38

 
 
 
 
 
 
 
 
 
 
 
 
 
 
General and administrative expenses were $4,352,000 for the year ended December 31, 2018, compared with $2,440,000 for the year ended December 31, 2017. This increase
of  $1,912,000  was  primarily  due  to  an  $896,000  insurance  reimbursement  received  by  the  Company  in  2017  for  legal  costs  and  a  $132,000  non-cash  reversal  of  stock
compensation expense related to unvested options for executives that are no longer with the Company which decreased expenses during the year ended December 31, 2017. The
Company also had increases in expenses during the year ended December 31, 2018 including approximately $141,000 in accounting fees related to SEC filings and $556,000 in
legal costs associated with both litigation and collaboration matters, as well as listing the Company on Nasdaq Capital Market.

In the ordinary course of business, the Company entered into non-cancelable related party leases for its facilities and convertible debt (see Note 15 – Transactions with Related
Parties in the following Consolidated Financial Statements).

Interest Income/Expense

Interest income (expense) was ($58,000) for the year ended December 31, 2018, compared to ($7,000) for the year ended December 31, 2017. The interest expense in 2017 and
2018 is primarily a result of the convertible promissory notes we entered into in November 2017 which were all converted to common stock in May 2018.

Other Income/Expense

Other income, net, was $294,000 for the year ended December 31, 2018 compared with $769,000 for the year ended December 31, 2017. Other income, net for the year ended
December 31, 2018 and 2017 primarily consisted of gains of $306,000 and $907,000, respectively, recognized from decreases in the fair value of our derivative liabilities as our
stock price decreased.

Income Taxes

For the year ended December 31, 2018, we recorded an income tax benefit of 13,582,000 resulting from reduction of our deferred tax liability primarily stemming from the
impairment loss recorded for the Company’s in-process research and development. For the year ended December 31, 2017, we recorded an income tax benefit of $6,880,000
primarily as a result of reduction of our deferred tax liability which was caused by recent tax law changes lowering the corporate tax rate to 21%.

Liquidity and Capital Resources

For the year ended December 31, 2018, net cash used in operating activities was $8,290,000, compared to net cash used in operating activities of $6,903,000 for 2017. The
increase in cash used in operating activities in 2018 as compared to 2017 was attributable to increased spending in research and development activities for the HCV Phase 2a
clinical trials. In 2018, net cash provided by investing activities netted to $1,372,000, which consisted of receipts related to our mortgage note offset by capital expenditures for
lab equipment, software, and computers for the relocated Miami office. For 2017, our net cash used in investing activities consisted of $40,000 in capital expenditures primarily
for lab equipment for our R&D facilities. For the year ended December 31, 2018, net cash provided by financing activities was $8,893,000, compared to net cash provided by
financing activities of $4,080,000 for 2017. Net cash generated by financing activities in 2018 and 2017 was the result of issuing convertible notes payable, exercises of stock
options, and additional issuances of common stock, including our 2018 follow-on offering.

On March 20, 2019, the Company by written notice suspended at-the-market sales of its common stock pursuant to the previously disclosed Equity Distribution Agreement,
dated  July  19,  2018  (the  “Distribution Agreement”)  by  and  among  the  Company,  Ladenburg  Thalmann  &  Co.  Inc.  (“Ladenburg”),  Barrington  Research Associates,  Inc.
(“Barrington”),  and Alliance  Global  Partners  (“AGP”).  Previously,  on  December  14,  2018,  the  Company  received  notice  from  Ladenburg  regarding  the  termination  of  its
engagement as a sales agent under the Distribution Agreement. On March 20, 2019, the Company terminated Barrington’s engagement as a sales agent under the Distribution
Agreement, effective March 21, 2019. The Distribution Agreement remains in place with respect to AGP, subject to the suspension of sales discussed above until further notice
is provided by the Company to AGP.

Based on cash on hand as of March 29, 2019 of approximately $8,700,000, the Company may not have the capital to finance its operations including any unforeseen expenses
such as higher than anticipated legal costs and uninsured catastrophe to the Company operations for the next 12 months.

39

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Company’s consolidated financial statements are prepared using generally accepted accounting principles in the United States of America applicable to a going concern,
which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has incurred net losses and negative operating cash
flows since inception. For the year ended December 31, 2018, the Company recorded a net loss of approximately $49,048,000 and used approximately $8,290,000 of cash in
operating activities. The Company has not yet established an ongoing source of revenue sufficient to cover its operating costs and allow it to continue as a going concern. The
ability of the Company to continue as a going concern is dependent on the Company obtaining adequate capital to fund operating losses until it becomes profitable.

The Company’s historical operating results indicate substantial doubt exists related to the Company’s ability to continue as a going concern. We can give no assurances that any
additional capital that we are able to obtain, if any, will be sufficient to meet our needs, or that any such financing will be obtainable on acceptable terms. If we are unable to
obtain adequate capital, we could be forced to cease operations or substantially curtail our commercial activities. These conditions raise substantial doubt as to our ability to
continue as a going concern. The accompanying financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts
and classification of liabilities should we be unable to continue as a going concern.

Cautionary Note Regarding Forward Looking Statements

This Annual  Report  includes  forward-looking  statements  within  the  meaning  of  The  Private  Securities  Litigation  Reform Act  of  1995,  including  statements  regarding  the
expected timing of release of Phase 2a HCV study results, the  commencement  of  our  Phase  2a  HCV  study  in  Hong  Kong,  the  expected  timing  of  initiation  of  our  Phase  1
influenza study, our collaboration with Merck pursuant to the Collaboration Agreement, and our liquidity.

The  words  “believe,”  “may,”  “estimate,”  “continue,”  “anticipate,”  “intend,”  “should,”  “plan,”  “could,”  “target,”  “potential,”  “is  likely,”  “will,”  “expect”  and  similar
expressions, as they relate to us, are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and
projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs.

The  results  anticipated  by  any  or  all  of  these  forward-looking  statements  might  not  occur.  Important  factors,  uncertainties  and  risks  that  may  cause  actual  results  to  differ
materially  from  these  forward-looking  statements  include  continued  collaboration  with  Merck,  the  availability  of  products  manufactured  by  third  parties,  and  the  ability  of
clinical research organizations to recruit subjects, favorable results of planned research and, if successful, clinical trials, and receipt of regulatory approvals. Further information
on such uncertainties and risks is contained in the “Risk Factors” in Item 1A of this this Annual Report. We undertake no obligation to publicly update or revise any forward-
looking statements, whether as the result of new information, future events or otherwise. For more information regarding some of the ongoing risks and uncertainties of our
business, see “Item 1A – Risk Factors” and our other filings with the SEC.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in
accordance  with  U.S.  Generally Accepted Accounting  Principles,  or  GAAP.  The  preparation  of  these  consolidated  financial  statements  requires  us  to  make  estimates  and
judgments that affect the reported amounts of assets, liabilities and expenses. On an ongoing basis, we evaluate these estimates and judgments, including those described below.
We  base  our  estimates  on  our  historical  experience  and  on  various  other  assumptions  that  we  believe  to  be  reasonable  under  the  circumstances.  These  estimates  and
assumptions  form  the  basis  for  making  judgments  about  the  carrying  values  of  assets  and  liabilities  that  are  not  readily  apparent  from  other  sources. Actual  results  and
experiences  may  differ  materially  from  these  estimates.  While  our  significant  accounting  policies  are  more  fully  described  in  the  accompanying  notes  to  the  consolidated
financial statements included in this Annual Report on Form 10-K for the year ended December 31, 2018, we believe that the following accounting policies are the most critical
to aid you in fully understanding and evaluating our reported financial results and affect the more significant judgments and estimates that we use in the preparation of our
consolidated financial statements.

Stock-Based Compensation

We account for stock options related to our equity incentive plans under the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification
(“ASC”) 718 which requires the recognition of the fair value of stock-based compensation. The fair value of stock options is estimated using a Black-Scholes option valuation
model. This model requires the input of subjective assumptions including expected stock price volatility, expected life and estimated forfeitures of each award. The fair value of
equity-based awards is amortized ratably over the requisite service period of the award. Due to the limited amount of historical data available to us, particularly with respect to
stock-price volatility, employee exercise patterns and forfeitures, actual results could differ from our assumptions.

Fair Value of Warrants

Warrants are recorded either as equity instruments or derivative liabilities. In the case of warrants recorded as liabilities, they are recorded at their estimated fair value at the
date of issuance. Subsequent changes in estimated fair value are recorded in other income (expense) in the Company’s statement of operations in each subsequent period. The
warrants are measured at estimated fair value using the Black Scholes valuation model, which is based, in part, upon inputs for which there is little or no observable market data,
requiring the Company to develop its own assumptions. Inherent in this model are assumptions related to expected stock price volatility, expected life, risk-free interest rate and
dividend yield. We estimate the volatility of our common stock at the date of issuance, and at each subsequent reporting period, based on a combination of the historical implied
volatility of our own stock price and that of a group of comparable companies, that matches the expected remaining life of the warrants. The risk-free interest rate is based on
the U.S. Treasury zero-coupon yield curve on the measurement date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is
assumed to be equivalent to their remaining contractual term. The dividend rate is based on our historical rate, which we anticipate to remain at zero. The assumptions used in
calculating the estimated fair value of the warrants represent our best estimates. However, these estimates involve inherent uncertainties and the application of management
judgment. As a result, if factors change and different assumptions are used, the warrant liability and the change in estimated fair value could be materially different.

Business Combinations and Intangible Assets

In connection with our acquisition of RFS Pharma in November 2014, we acquired a substantial amount of intellectual property. We have accounted for the intellectual property
acquired as an in-process research and development (IPR&D) asset and have determined that asset to have an indefinite life based on the stage of development of the research
projects of RFS Pharma at the date of acquisition. This intangible asset, which we recorded at its estimated fair value of $184,966,000 as of the acquisition date, will continue to
have  an  indefinite  life  until  the  associated  research  and  development  activities  are  complete,  at  which  point  a  determination  of  the  asset’s  useful  life  will  be  made.  Prior  to
completion of these research and development activities, the intangible asset will be subject to annual impairment tests, or more frequent tests in the event of any impairment
indicators occurring. These impairment tests require significant judgment regarding the status of the research activities, the potential for future revenues to be derived from any
products that may result from those activities, and other factors.

The  Company  conducts  its  annual  impairment  test  related  to  the  in-process  research  and  development  asset  as  of  November  30  each  year.  The  initial  valuation  recorded  in
November  2014  at  the  time  of  the  RFS  Pharma  acquisition  represented  the  fair  value  of  the  acquired  hepatitis  C  program  acquired  from  RFS  Pharma.  We  perform  our
impairment test using the income approach (also known as the discounted cash flow (“DCF”) method, which utilizes the present value of future cash flows to estimate fair
value). The future cash flows for our hepatitis C assets are projected based upon our estimates of future revenues, operating income and other factors (such as working capital
and capital expenditures). We take into account market conditions for hepatitis C therapies, anticipated new competitive therapies and anticipated market prices of our potential
future products as we model future cash flows.

Late in 2015, the Company received reports from ongoing pre-clinical studies that indicated higher than acceptable toxicity related to its hepatitis C lead molecule, CC-1845. As
a result, in 2015 we lowered our forecasts of future cash flows, which caused a reduction in value of our hepatitis C assets and which led to an impairment charge recorded in the
amount of $38,665,000 in 2015 related to our IPR&D asset.

41

 
 
 
 
 
 
 
 
 
 
In November 2016, due to industry reports forecasting patient volume decreasing and the average price of treatment trending downward, as well as due to increased competition
in  the  hepatitis  C  market,  and  partially  the  result  of  further  data  defining  the  scientific  and  commercial  potential  of  Company  HCV  compounds,  we  further  lowered  our
forecasted cash flows, which resulted in an impairment of our IPR&D asset in the amount of $92,396,000 in 2016. In late 2018, the Company concluded that given the success
of CC-31244 in clinical trials, the Hepatitis C program would move forward solely with CC-31244 without any of the compounds acquired from RFS Pharma. As part of this
decision, the Company abandoned all remaining in process research and development intangible assets recognized by the Company and thereafter, we executed our right to
terminate the license with Emory on December 6, 2018 (see Note 11 – Licenses and Collaborations). This resulted in a $53,905,000 impairment in 2018.

We also recorded $65,195,000 of goodwill in the RFS Pharma acquisition that is subject to impairment testing. This goodwill primarily represents the amount initially recorded
as a deferred tax liability in the RFS Pharma acquisition, which was required as the goodwill recorded for book purposes is not tax deductible based on the structure of the
acquisition. Future impairment tests of goodwill will also require substantial judgment and estimates. We completed our annual goodwill impairment tests as of November 30,
2018 and 2017, and determined that there was no impairment of goodwill in any period.

Income Taxes

In 2017, our deferred tax liability declined by $6,880,000 due to the impact of recent changes in the tax laws which, among other things, lowered the corporate tax rate to 21%.
The remeasurement of our deferred tax liability generated an income tax benefit of $6,880,000. In addition to lowering the corporate tax rate for years beginning January 1,
2018, the new tax laws allow for net operating loss carryforwards (“NOL”) to be carried forward indefinitely for losses incurred beginning in 2018, subject to a limitation on the
amount that can be used to offset income generated in a given year. Given the change in tax laws, we considered whether the reversal of taxable temporary differences related to
the indefinite lived intangible assets may be used as a source of future taxable income in assessing the realizability of deferred tax assets that upon reversal would give rise to
NOLs that do not expire, which resulted in an additional tax benefit of approximately $6,880,000 in 2017.

In 2018, there was no additional impact to our income taxes due to the tax law changes which were measured in 2017 and noted above. The primary driver of 2018 tax benefits
recognized was due to the write off of indefinite lived IPR&D intangible assets. We recorded an income tax benefit of $13,582,000 and eliminated the deferred tax liability in
our consolidated balance sheet as of December 31, 2018. Further, the federal net operating loss generated in 2018 of $8,829,000 will carry forward indefinitely and be available
to offset up to 80% of future taxable income. We continue to recognize a full valuation allowance against our net federal and state deferred tax assets at December 31, 2018 as
the Company has generated cumulative losses since inception. To the extent the Company starts generating pre-tax book income and/or has other circumstances that would
result in the utilization of our net deferred tax assets, our determination regarding the valuation allowance may also change.

 Item 9A. Controls and Procedures

Our  management,  with  the  participation  of  our  interim  Chief  Executive  Officer  and  Chief  Financial  Officer,  have  evaluated  the  effectiveness  of  the  Company’s  disclosure
controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2018. Our disclosure controls and procedures are designed to
provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized
and  reported,  within  the  time  periods  specified  in  the  rules  and  forms  of  the  SEC.  Disclosure  controls  and  procedures  include,  without  limitation,  controls  and  procedures
designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the
company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based upon
that evaluation, management concluded that our disclosure controls and procedures were not effective as of December 31, 2018 as a result of the material weaknesses in our
internal control over financial reporting described below in the “Management’s Annual Report on Internal Controls over Financial Reporting.”.

Management’s Report on Internal Control over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting  as  defined  in  Rules  13a-15(f)  and  15d-15(f)  under  the
Exchange Act.  Our  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the
preparation  of  financial  statements  for  external  purposes  in  accordance  with  generally  accepted  accounting  principles.  All  internal  control  systems,  no  matter  how  well
designed, have inherent limitations. Therefore, even those systems determined effective could provide only reasonable assurance with respect to financial statement preparation
and  presentation. Also,  projections  of  any  evaluation  of  effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate  because  of  changes  in
conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management is also required to assess and report on the effectiveness of our internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley
Act of 2002 (“Section 404”). Our management conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2018, based on
the framework in the Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “2013 Internal
Control-Integrated Framework”).

A  material  weakness  is  a  deficiency,  or  combination  of  deficiencies,  in  internal  control  over  financial  reporting  such  that  there  is  a  reasonable  possibility  that  a  material
misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

During  the  year  ended  December  31,  2017,  management  identified  certain  material  weaknesses  related  to  (i)  ineffective  preparation  and  review  of  manual  account
reconciliations and (ii) an ineffective financial reporting process with respect to preparation of financial statements in accordance with U.S. GAAP. During the fourth quarter of
2018, management concluded that the previously identified material weaknesses were not remediated as of December 31, 2018, primarily due to the timing of the turnover in
our accounting team and the effect of such timing on the transition of responsibilities related to the execution of control activities during the fourth quarter of 2018.

During  our  assessment  of  the  effectiveness  of  internal  control  over  financial  reporting  as  of  December  31,  2018,  our  management  concluded  that  our  Company  has  the
following material weaknesses in internal control over financial reporting as of December 31, 2018:

Risk Assessment and Control Activities - Management’s Review and Supervision of the Financial Reporting Process

We did not maintain an effective financial reporting process to prepare and present our financial statements in accordance with accounting principles generally accepted in the
United States of America. Specifically, the process lacked detailed reviews over the completeness and accuracy of information included in the financial statements. This control
deficiency resulted in the reasonable possibility that a material misstatement in the consolidated financial statements would not be prevented or detected on a timely basis.

43

 
 
 
 
 
 
 
 
 
 
 
 
Control Activities – Management’s Review over Technical Accounting Matters and Account Reconciliations

Our  design  and  maintenance  of  controls  in  the  period  end  financial  reporting  process  over  management’s  analysis  and  review  of  technical  accounting  matters  and  account
reconciliations  (including  goodwill,  capital  leases,  warrants,  stock  options  and  convertible  debt),  were  ineffective. This  material  weakness  could  result  in  a  material
misstatement to the Company’s annual or interim financial statements that would not be prevented or detected.

As a result of the material weaknesses noted above, we completed additional procedures prior to filing this Annual Report on Form 10-K for the year ended December 31, 2018.
Based on these procedures, management believes that our consolidated financial statements included in this Annual Report on Form 10-K have been prepared in accordance
with  generally  accepted  accounting  principles.  Our  chief  executive  officer  and  principal  financial  officer  have  certified  that,  based  on  each  such  officer’s  knowledge,  the
financial  statements,  and  other  financial  information  included  in  this Annual  Report  on  Form  10-K,  fairly  present  in  all  material  respects  our  financial  condition,  results  of
operations, and cash flows as of, and for, the periods presented in this Annual Report on Form 10-K.

Our  independent  registered  public  accounting  firm  also  attested  to,  and  reported  on,  the  Company’s  Internal  Control  over  Financial  Reporting,  which  report  expressed  an
adverse opinion on the effectiveness of our internal controls over financial reporting as of December 31, 2018.

Changes in Internal Control over Financial Reporting

Unless otherwise noted above, there were no changes in internal control over financial reporting that occurred during the year ended December 31, 2018, that have materially
affected,  or  are  reasonably  likely  to  materially  affect,  our  internal  control  over  financial  reporting. Management  concluded  that  certain  previously  identified  material
weaknesses, described above, were not remediated as of December 31, 2018, primarily due to the timing of the turnover in our management team and the effect of such timing
on the transition of responsibilities related to the execution of control activities.

Remedial Actions to Address Material Weaknesses

With input and oversight from the Audit Committee, management is actively implementing a remediation plan to ensure that control deficiencies contributing to the material
weaknesses were remediated such that these controls will operate effectively. We are taking, and expect to continue to take the following remediation actions:

(i)

the implementation  of  additional  review  procedures  designed  to  enhance  the  control  owner’s execution  of  controls  activities,  including  entity  level  controls,  through  the
implementation of improved documentation standards evidencing execution of these controls, oversight, and training;

(ii) improvement of the control activities and procedures associated with the review of complex accounting areas, including proper segregation of duties and assigning personnel

with the appropriate experience as preparers and reviewers over analyses relating to such accounting areas;

(iii) educating and re-training control owners regarding internal control processes to mitigate identified risks and maintaining adequate documentation to evidence the effective

design and operation of such processes; and

(iv) implementing enhanced controls to monitor the effectiveness of the underlying business process controls that are dependent on the data and financial reports generated from

the relevant information systems.

We  believe  that  these  actions,  and  the  improvements  we  expect  to  achieve  as  a  result,  will  effectively  remediate  the  material  weaknesses  identified  in  2018.  However,  the
material weaknesses in our internal control over financial reporting will not be considered remediated until the remediated controls operate for a sufficient period of time and
management has concluded, through testing, that these controls are operating effectively. We expect that the remediation of these material weaknesses will be completed in
2019.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Cocrystal Pharma, Inc.
Bothell, Washington

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Cocrystal Pharma, Inc. (the “Company”) and subsidiaries as of December 31, 2018 and 2017, the related
consolidated statements of operations, stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial
statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2018 and 2017,
and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over
financial  reporting  as  of  December  31,  2018,  based  on  criteria  established  in Internal  Control  –  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring
Organizations of the Treadway Commission (“COSO”) and our report dated April 1, 2019 expressed an adverse opinion thereon.

Going Concern Uncertainty

The  accompanying  consolidated  financial  statements  have  been  prepared  assuming  that  the  Company  will  continue  as  a  going  concern.  As  discussed  in  Note  1  to  the
consolidated financial statements, the Company has suffered recurring losses from operations, negative cash flows from operations and has an accumulated deficit that raise
substantial  doubt  about  its  ability  to  continue  as  a  going  concern.  Management’s  plans  in  regard  to  these  matters  are  also  described  in  Note  1.  The  consolidated  financial
statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the  Company’s  consolidated
financial  statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  PCAOB  and  are  required  to  be  independent  with  respect  to  the  Company  in
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our 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 consolidated financial statements are free of material misstatement, whether due to error or fraud.

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

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Cocrystal Pharma, Inc.
Bothell, Washington

Opinion on Internal Control over Financial Reporting

We  have  audited  Cocrystal  Pharma,  Inc.’s  (the  “Company’s”)  internal  control  over  financial  reporting  as  of  December  31,  2018,  based  on  criteria  established  in Internal
Control  –  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (the  “COSO  criteria”).  In  our  opinion,  the
Company did not maintain, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on the COSO criteria.

We  do  not  express  an  opinion  or  any  other  form  of  assurance  on  management’s  statements  referring  to  any  corrective  actions  taken  by  the  Company  after  the  date  of
management’s assessment.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets of the
Company as of December 31, 2018 and 2017, the related consolidated statements of operations, stockholders’ equity, and cash flows for the years then ended, and the related
notes (collectively referred to as “the consolidated financial statements”) and our report dated April 1, 2019 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over
financial reporting, included in the accompanying “Item 9A – Management’s Report on Internal Control over Financial Reporting”. Our responsibility is to express an opinion
on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent
with  respect  to  the  Company  in  accordance  with  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange  Commission  and  the
PCAOB.

We conducted our audit of internal control over financial reporting in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit
to  obtain  reasonable  assurance  about  whether  effective  internal  control  over  financial  reporting  was  maintained  in  all  material  respects.  Our  audit  included  obtaining  an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of
internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit
provides a reasonable basis for our opinion.

A  material  weakness  is  a  deficiency,  or  a  combination  of  deficiencies,  in  internal  control  over  financial  reporting,  such  that  there  is  a  reasonable  possibility  that  a  material
misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. Material weaknesses regarding management’s failure
to  maintain  an  effective  financial  reporting  process  to  ensure  there  were  timely  and  documented  reviews  over  completeness  and  accuracy  of  information  included  in  the
financial statements, and management’s failure to design and maintain controls over management’s review of technical accounting matters and account reconciliations, have
been identified and described in management’s assessment. These material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in
our audit of the 2018 financial statements, and this report does not affect our report dated April 1, 2019 on those financial statements.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those
policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the
company;  (2)  provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  generally  accepted
accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company;
and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material
effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to
future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures
may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Business

Cocrystal Pharma, Inc. (“we”, the “Company” or “Cocrystal”), a biopharmaceutical company, has been developing novel technologies and approaches to create first-in-class
and  best-in-class  antiviral  drug  candidates  since  its  initial  funding  in  2008.  Our  focus  is  to  pursue  the  development  and  commercialization  of  broad-spectrum  antiviral  drug
candidates that will transform the treatment and prophylaxis of viral diseases in humans. By concentrating our research and development efforts on viral replication inhibitors,
we plan to leverage our infrastructure and expertise in these areas.

The  Company  was  formerly  incorporated  in  Nevada  under  the  name  Biozone  Pharmaceuticals,  Inc.  (“Biozone”).  On  January  2,  2014,  Biozone  Pharmaceuticals,  Inc.  sold
substantially all of its assets to MusclePharm Corporation (“MusclePharm”), and, on the same day, merged with Cocrystal Discovery, Inc. in a transaction accounted for as a
reverse merger. Following the merger, the Company assumed Cocrystal Discovery, Inc.’s business plan and operations. On March 18, 2014, the Company reincorporated in
Delaware under the name Cocrystal Pharma, Inc.

Effective November 25, 2014, Cocrystal Pharma, Inc. and affiliated entities completed a series of merger transactions as a result of which Cocrystal Pharma, Inc. merged with
RFS Pharma, LLC, a Georgia limited liability company (“RFS Pharma”). We refer to the surviving entity of this merger as “Cocrystal” or the “Company.”

On January 18, 2018, the Company’s Board of Directors (the “Board”) filed an amendment (the “Amendment”) with the Delaware Secretary of State to affect a one-for-thirty
reverse split (the “Reverse Stock Split”) of the Company’s class of common stock. The Amendment took effect on January 24, 2018. The Reverse Stock Split did not change
the authorized number of shares of common stock. Pursuant to the terms of the Company’s then outstanding convertible notes (see Note 8 – Convertible Notes Payable), its
options and warrants have been proportionately adjusted to reflect the Reverse Stock Split. A proportionate adjustment was made to the per share exercise price, number of
shares issued and shares reserved for issuance under all of the Company’s equity compensation plans.

All per share amounts and number of shares in the consolidated financial statements and related notes presented have been retroactively restated to reflect the Reverse Stock
Split.

The  Company’s  activities  since  inception  have  principally  consisted  of  acquiring  product  and  technology  rights,  raising  capital,  and  performing  research  and  development.
Successful  completion  of  the  Company’s  development  programs,  obtaining  regulatory  approvals  of  its  products  and,  ultimately,  the  attainment  of  profitable  operations  is
dependent  on  future  events,  including,  among  other  things,  its  ability  to  access  potential  markets,  secure  financing,  develop  a  customer  base,  attract,  retain  and  motivate
qualified personnel, and develop strategic alliances. Through December 31, 2018, the Company has primarily funded its operations through equity offerings.

The  Company’s  historical  operating  results  indicate  substantial  doubt  exists  related  to  the  Company’s  ability  to  continue  as  a  going  concern.  The  Company  has  no
pharmaceutical  products  approved  for  sale,  has  not  generated  any  revenues  to  date  from  pharmaceutical  product  sales,  and  has  incurred  significant  operating  losses  since
inception. The Company has never been profitable and has incurred losses from operations of $62,924,000 and $8,262,000 in the years ended December 31, 2018 and 2017,
respectively.

In July 2018, the Company entered into an Equity Distribution Agreement (the “Distribution Agreement”) with Ladenburg Thalmann & Co. Inc. (“Ladenburg”), Barrington
Research Associates, Inc. (“Barrington”), and Alliance Global Partners (“AGP” and together the “Sales Agents”), pursuant to which, and at the Company’s sole discretion, may
issue and sell over time, and from time to time, to or through the Sales Agents, up to $10,000,000 worth of shares of the Company’s common stock. As of December 31, 2018,
we  have  not  sold  any  shares  of  common  stock  under  the  Distribution Agreement.  On  December  14,  2018,  Ladenburg  terminated  its  engagement  as  a  sales  agent  under  the
Distribution Agreement.

F-8

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
On March 20, 2019, the Company by written notice suspended at-the-market sales of its common stock pursuant to the Distribution Agreement. The Company also terminated
the agreement with Barrington effective March 21, 2019. The Distribution Agreement remains in place with respect to AGP, subject to the suspension of sales discussed above
until further notice is provided by the Company to AGP.

Subsequent  to  year-end,  on  January  31,  2019,  the  Company  received  an  upfront  non-refundable  payment  of  $4,000,000  and  anticipates  future  payments  for  employees  and
research expense reimbursements over the term of our collaboration with Merck Sharp & Dohme Corp. (“Merck”), effective January 2, 2019 (refer to Note 11, Licenses and
Collaborations).

The Company will need to continue obtaining adequate capital to fund operating losses until it becomes profitable. The Company can give no assurances that the additional
capital  it  is  able  to  raise,  if  any,  will  be  sufficient  to  meet  its  needs,  or  that  any  such  financing  will  be  obtainable  on  acceptable  terms.  If  the  Company  is  unable  to  obtain
adequate capital, it could be forced to cease operations or substantially curtail its drug development activities. The Company expects to continue incurring substantial operating
losses and negative cash flows from operations over the next several years during its pre-clinical and clinical development phases.

2. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), and pursuant to the
rules and regulations of the Securities and Exchange Commission (“SEC”) for reporting of annual financial information.

Principles of Consolidation

The  consolidated  financial  statements  include  the  accounts  of  Cocrystal  Pharma,  Inc.  and  its  wholly  owned  subsidiaries:  RFS  Pharma,  LLC,  Cocrystal  Discovery,  Inc.,
Cocrystal Merger Sub, Inc., Baker Cummins Corp. and Biozone Laboratories, Inc. Intercompany transactions and balances have been eliminated.

Segments

The  Company  operates  in  only  one  segment.  Management  uses  cash  flows  as  the  primary  measure  to  manage  its  business  and  does  not  segment  its  business  for  internal
reporting or decision-making.

Use of Estimates

Preparation of the Company’s consolidated financial statements in conformance with U.S. GAAP requires the Company’s management to make estimates and assumptions that
impact  the  reported  amounts  of  assets,  liabilities,  revenues  and  expenses,  and  the  disclosure  of  contingent  assets  and  liabilities  in  the  Company’s  consolidated  financial
statements  and  accompanying  notes.  The  significant  estimates  in  the  Company’s  consolidated  financial  statements  relate  to  the  valuation  of  equity  awards  and  derivative
liabilities,  recoverability  of  deferred  tax  assets,  estimated  useful  lives  of  fixed  assets,  and  forecast  assumptions  used  in  the  valuation  of  intangible  assets  and  goodwill.  The
Company  bases  estimates  and  assumptions  on  historical  experience,  when  available,  and  on  various  factors  that  it  believes  to  be  reasonable  under  the  circumstances.  The
Company evaluates its estimates and assumptions on an ongoing basis, and its actual results may differ from estimates made under different assumptions or conditions.

F-9

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Concentrations of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash deposited in accounts held at two U.S. financial
institutions, which may, at times, exceed federally insured limits of $250,000 for each institution accounts are held. At December 31, 2018 and 2017, our primary operating
account held approximately $2,723,000 and $748,000, respectively, and our collateral account balance was $29,000 at a different institution. The Company has not experienced
any losses in such accounts and believes it is not exposed to significant risks thereof.

Risks and Uncertainties

The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results
to  vary  materially  from  expectations  include,  but  are  not  limited  to,  rapid  technological  change,  ability  to  obtain  regulatory  approvals,  competition  from  currently  available
treatments  and  therapies,  competition  from  larger  companies,  effective  protection  of  proprietary  technology,  maintenance  of  strategic  relationships,  and  dependence  on  key
individuals.

Products  developed  by  the  Company  will  require  clearances  from  the  U.S.  Food  and  Drug Administration  (the  “FDA”)  and  other  international  regulatory  agencies  prior  to
commercial sales in their respective markets. The Company’s products may not receive the necessary clearances and if they are denied clearance, clearance is delayed, or the
Company is unable to maintain clearance, the Company’s business could be materially, adversely impacted.

Cash and Restricted Cash

The Company considers all highly liquid investments with an original maturity from the date of purchase of three months or less to be cash equivalents, and the Company held
no cash equivalents as of December 31, 2018 and 2017.

The following table provides a reconciliation of cash and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amounts shown in
the consolidated statements of cash flows (in thousands):

Restricted cash represents amounts pledged as collateral for financing arrangements that are currently limited to the issuance of business credit cards. The restriction will end
upon the conclusion of these financing arrangements.

Property and Equipment

Property and equipment, which consists of lab equipment (including lab equipment under capital lease), computer equipment, and office equipment, is recorded at cost and
depreciated over the estimated useful lives of the underlying assets (three to five years) using the straight-line method.

Leases

Lease agreements entered into by the Company are evaluated to determine whether they are capital leases or operating leases. The Company considers a capital lease if it meets
one of the following criteria: a.) Transfer of ownership. The lease transfers ownership of the property to the lessee by the end of the lease term. This criterion is met in situations
in  which  the  lease  agreement  provides  for  the  transfer  of  title  at  or  shortly  after  the  end  of  the  lease  term  in  exchange  for  the  payment  of  a  nominal  fee,  for  example,  the
minimum required by statutory regulation to transfer title. b.) Bargain purchase option. The lease contains a bargain purchase option. c.) Lease term. The lease term is equal to
75 percent or more of the estimated economic life of the leased property. d.) Minimum lease payments. The present value at the beginning of the lease term of the minimum
lease payments, excluding that portion of the payments representing executory costs such as insurance, maintenance, and taxes to be paid by the lessor, including any profit
thereon, equals or exceeds 90 percent of the excess of the fair value of the leased property to the lessor at lease inception over any related investment tax credit retained by the
lessor and expected to be realized by the lessor.

In 2018, the Company entered into two new lease agreements for lab equipment which meet the criteria for capital leases due to transfer of ownership at lease-end for a nominal
fee. Additionally, the Company had two operating leases for office facilities at year-end (see Note 14 – Commitments and Contingencies).

Fair Value Measurements

FASB Accounting Standards Codification (“ASC”) 820 defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles and
enhances disclosures about fair value measurements. Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability
(an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation
techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair
value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the
following:

Level 1 — quoted prices in active markets for identical assets or liabilities.

Level 2 — other significant observable inputs for the assets or liabilities through corroboration with market data at the measurement date.

Level 3  —  significant  unobservable  inputs  that  reflect  management’s  best  estimate  of  what  market  participants  would use  to  price  the  assets  or  liabilities  at  the
measurement date.

The Company categorizes its cash as Level 1 fair value measurements. The Company categorizes its warrants potentially settleable in cash as Level 3 fair value measurements.
The warrants potentially settleable in cash are measured at fair value on a recurring basis and are being marked to fair value at each reporting date until they are completely
settled or meet the requirements to be accounted for as component of stockholders’ equity. The warrants are valued using the Black-Scholes option pricing model as discussed in
Note 10 – Warrants.

The following tables presents a summary of fair values of assets and liabilities that are re-measured at fair value at each balance sheet date presented as of December 31, 2018
and 2017, and their placement within the fair value hierarchy as discussed above (in thousands):

We account for business combinations using the acquisition method, recording the acquisition-date fair value of total consideration over the acquisition-date fair value of net
assets acquired as goodwill. Acquisition-related costs, including banking, legal, accounting, valuation, and other similar costs, are expensed in the periods in which the costs are
incurred  and  included  in  loss  from  operations  in  the  consolidated  financial  statements.  The  results  of  operations  of  the  acquired  business  are  included  in  the  consolidated
financial statements from the acquisition date.

In  November  2014,  goodwill  and  intangible  assets  for  in-process  research  and  development  were  recorded  in  connection  with  the  acquisition  of  RFS  Pharma,  and  have
represented a series of awarded patents, filed patent applications and an in-process research program acquired related to Hepatitis C compound development.

We  evaluate  indefinite-lived  intangible  assets  and  goodwill  for  impairment  annually,  as  of  November  30,  or  more  frequently  when  events  or  circumstances  indicate  that
impairment may have occurred. As part of the impairment evaluation, we may elect to perform an assessment of qualitative factors. If this qualitative assessment indicates that
it is more likely than not that the fair value of the indefinite-lived intangible asset or the reporting unit (for goodwill) is less than its carrying value, we then would proceed with
the quantitative impairment test to compare the fair value to the carrying value and record an impairment charge if the carrying value exceeds the fair value.

Fair value is typically estimated using an income approach based on the present value of future discounted cash flows. The significant estimates in the discounted cash flow
model primarily include the discount rate, and rates of future revenue and expense growth and/or profitability of the acquired assets. In performing the impairment test, the
Company  considered,  among  other  factors,  the  Company’s  intention  for  future  use  of  acquired  assets,  analyses  of  historical  financial  performance  and  estimates  of  future
performance of Cocrystal’s product candidates.

In-process  research  and  development  assets  are  accounted  for  as  indefinite-lived  intangible  assets  and  maintained  on  the  balance  sheet  until  either  the  underlying  project  is
completed  or  the  asset  becomes  impaired.  If  the  project  is  completed,  the  carrying  value  of  the  related  intangible  assets  are  amortized  to  cost  of  sales  over  the  remaining
estimated life of the asset(s), beginning in the period in which the project is completed. If the intangible asset becomes impaired or the related project is abandoned, the carrying
value of the underlying intangible asset is written down to its fair value and an impairment charge is recorded in the period in which the impairment occurs and included in
operating expenses under research and development within the relative consolidated statement of operations.

The Company has a lead compound, CC-31244, for its Hepatitis C program, which was created at the Company’s labs in Bothell, Washington, and not part of the acquisition
from RFS Pharma. In 2016, the Company initiated and completed a Phase 1A trial with compound CC-31244, and began a Phase 1B trial with CC-31244 that was completed in
2017. In 2018, the Company began a Phase 2A clinical trial with CC-31244 and recently released interim results in January 2019. In late 2018, the Company concluded that
given the success of CC-31244 in clinical trials, the Hepatitis C program would move forward solely with CC-31244 without any of the compounds acquired from RFS Pharma.
As part of this decision, the Company abandoned all remaining in process research and development intangible assets recognized by the Company and thereafter, terminated its
license with Emory University on December 6, 2018 (see Note 11 – Licenses and Collaborations). This resulted in a $53,905,000 impairment in 2018. At December 31, 2018
and 2017, $0 and $53,905,000 was included as in process research and development on the Company’s consolidated balance sheets, respectively.

At  December  31,  2018  and  2017,  the  Company  had  goodwill  of  $65,195,000  and  determined  the  fair  value  of  its  reporting  unit,  under  both  the  Company’s  Nasdaq  market
capitalization and an income approach analysis; both methods exceeded the carrying value as of December 31, 2018; therefore, management did not consider goodwill to be
impaired.

Long-Lived Assets

The Company regularly reviews the carrying value and estimated lives of its long-lived assets, including property and equipment, to determine whether indicators of impairment
may exist which warrant adjustments to carrying values or estimated useful lives. The determinants used for this evaluation include management’s estimate of the asset’s ability
to generate positive income from operations and positive cash flow in future periods as well as the strategic significance of the assets to the Company’s business objective.
Should an impairment exist, the impairment loss would be measured based on the excess of the carrying amount over the asset’s fair value.

Mortgage Note Receivable

As discussed in Note 4, the Company’s mortgage note receivable was collected in full during 2018.

The  Company  records  its  mortgage  note  receivable  at  the  amount  advanced  to  the  borrower,  which  includes  the  stated  principal  amount  and  certain  loan  origination  and
commitment fees that are recognized over the term of the mortgage note. Interest income is accrued as earned over the term of the mortgage note. The Company evaluates the
collectability of both interest and principal of the note to determine whether it is impaired. The note is considered impaired if, based on current information and events, the
Company  determines  that  it  is  probable  that  it  would  be  unable  to  collect  all  amounts  due  according  to  the  existing  contractual  terms.  Upon  determination  that  the  note  is
impaired, the amount of loss is calculated by comparing the recorded investment to the value determined by discounting the expected future cash flows at the note’s effective
interest rate or to the fair value of the Company’s interest in the underlying collateral, less the cost to sell.

Research and Development Expenses

All research and development costs are expensed as incurred.

Income Taxes

The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between
financial reporting and tax bases of assets and liabilities and are measured using enacted tax rates and laws that are expected to be in effect when the differences are expected to
be recovered or settled. Realization of deferred tax assets is dependent upon future taxable income. A valuation allowance is recognized if it is more likely than not that some
portion or all of a deferred tax asset will not be realized based on the weight of available evidence, including expected future earnings. The Company recognizes an uncertain
tax position in its financial statements when it concludes that a tax position is more likely than not to be sustained upon examination based solely on its technical merits. Only
after a tax position passes the first step of recognition will measurement be required. Under the measurement step, the tax benefit is measured as the largest amount of benefit
that  is  more  likely  than  not  to  be  realized  upon  effective  settlement.  This  is  determined  on  a  cumulative  probability  basis.  The  full  impact  of  any  change  in  recognition  or
measurement is reflected in the period in which such change occurs. The Company elects to accrue any interest or penalties related to income taxes as part of its income tax
expense.

Stock-Based Compensation

The Company recognizes compensation expense using a fair value-based method for costs related to stock-based payments, including stock options. The fair value of options
awarded to employees is measured on the date of grant using the Black-Scholes option pricing model and is recognized as expense over the requisite service period on a straight-
line basis.

Use  of  the  Black-Scholes  option  pricing  model  requires  the  input  of  subjective  assumptions  including  expected  volatility,  expected  term,  and  a  risk-free  interest  rate.  The
Company estimates volatility using a blend of its own historical stock price volatility as well as that of market comparable entities since the Company’s common stock has
limited  trading  history  and  limited  observable  volatility  of  its  own.  The  expected  term  of  the  options  is  estimated  by  using  the  Securities  and  Exchange  Commission  Staff
Bulletin No. 107’s Simplified Method for Estimate Expected Term. The risk-free interest rate is estimated using comparable published federal funds rates.

Convertible Notes Payable

The Company accounts for convertible notes payable (when it has determined that the embedded conversion options should not be bifurcated from their host instruments) in
accordance  with ASC  470-20, Debt with Conversion and Other Options. Accordingly, the Company records, when necessary, discounts to convertible notes payable for the
intrinsic value of conversion options embedded in debt instruments based upon the differences between the fair value of the underlying common stock at the commitment date
of the note transaction and the effective conversion price embedded in the note. Debt discounts under these arrangements are amortized over the term of the related debt to their
earliest date of redemption. The Company determined that the embedded conversion options in its issued convertible notes payable do not meet the definition of a derivative
liability.

Common Stock Purchase Warrants and Other Derivative Financial Instruments

We  classify  as  equity  any  contracts  that  require  physical  settlement  or  net-share  settlement  or  provide  us  a  choice  of  net-cash  settlement  or  settlement  in  our  own  shares
(physical settlement or net-share settlement) provided that such contracts are indexed to our own stock as defined in ASC 815-40, Contracts in Entity’s Own Equity. We classify
as assets or liabilities any contracts that require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside our
control) or give the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement). We assess classification of our common
stock purchase warrants and other freestanding derivatives at each reporting date to determine whether a change in classification between assets and liabilities is required.

Recent Accounting Pronouncements

The following are new FASB Accounting Standards Updates (“ASUs”) that have been adopted by the Company as of December 31, 2018:

In August  2016,  the  FASB  issued ASU  No.  2016-15, Statement  of  Cash  Flows  (Topic  230),  which  addresses  the  classification  of  eight  specific  cash  flow  issues  with  the
objective of reducing the existing diversity in practice. The required adoption of ASU 2016-15 in the first quarter of 2018 did not have a significant impact on our consolidated
financial statements.

F-14

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  November  2016,  the  FASB  issued ASU  2016-18, Statement  of  Cash  Flows  (Topic  230):  Restricted  Cash  (“ASU  2016-18”).  The  guidance  requires  that  an  explanation  is
included in the cash flow statement of the change in the total of (1) cash, (2) cash equivalents, and (3) restricted cash or restricted cash equivalents. The ASU also clarifies that
transfers between cash, cash equivalents and restricted cash or restricted cash equivalents should not be reported as cash flow activities and requires the nature of the restrictions
on cash, cash equivalents, and restricted cash or restricted cash equivalents to be disclosed. We early adopted ASU 2016-18 at December 31, 2017 and disclosure revisions have
been made for the years presented in the notes to consolidated financial statements. 

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, to eliminate the second step
of the goodwill impairment test. ASU No. 2017-04 requires an entity to measure a goodwill impairment loss as the amount by which the carrying value of a reporting unit
exceeds its fair value. Additionally, an entity should include the income tax effects from any tax-deductible goodwill on the carrying value of the reporting unit when measuring
a goodwill impairment loss, if applicable. We early adopted the provisions of ASU 2017-04 prospectively in the fourth quarter of 2018. The adoption of ASU 2017-04 did not
have a material impact on the Company’s consolidated financial statements and related disclosures.

In  June  2018,  the  FASB  issued ASU  2018-07, Compensation—Stock  Compensation  (Topic  718):  Improvements  to  Nonemployee  Share-Based  Payment  Accounting,  which
expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 will be effective for public
business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year, with early adoption permitted, provided the entity has also
adopted ASC Topic 606,  Revenue from Contracts with Customers. The Company early adopted ASU 2018-07 in the fourth quarter of 2018, and there was no impact to stock
compensation expense recorded in on our consolidated statements of operations for the years ended 2018 and 2017. Refer to Note 9 – Share Based Awards for explanation of
the  Company’s  measurement  of  fair  value  for  incentive  awards  issued. As  required  per  the  adoption  criteria  of ASU  2018-07,  the  Company  has  concurrently  adopted ASC
Topic 606, which had no impact on our consolidated financial statements and related footnote disclosures.

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. This ASU provides
guidance  on  whether  certain  transactions  between  collaborative  arrangement  participants  should  be  accounted  for  as  revenue  under  Topic  606  when  the  collaborative
arrangement participant is a customer in the context of a unit of account. Accordingly, this amendment added unit of account guidance in Topic 606 when an entity is assessing
whether the collaborative arrangement, or a part of the arrangement, is within the scope of Topic 606. In addition, the amendment provides certain guidance on presenting the
collaborative arrangement transaction together with Topic 606. ASU 2018-18 is effective for fiscal years beginning after December 15, 2019 and interim periods within those
fiscal years and early adoption is permitted. This ASU is to be applied retrospectively to the date of initial application of Topic 606. The Company has early adopted ASU 2018-
18, effective in the fourth quarter of 2018 with no impact on our consolidated financial statements and related footnote disclosures.

The following are new FASB Accounting Standards Updates that have not been adopted by the Company as of December 31, 2018, and contain detail regarding the effective
dates:

In February 2016, the FASB issued ASU No. 2016-02, Leases, which was subsequently amended by ASU No. 2018-01, ASU No. 2018-10 and ASU No. 2018-11 (collectively,
“ASC 842”). Under this standard, which applies to both lessors and lessees, lessees will be required to recognize all leases (except for short-term leases) as a lease liability,
which is a lessee’s obligation to make lease payments arising from a lease measured on a discounted basis, and as a right-of-use asset, which is an asset that represents the
lessee’s right to use, or control the use of, a specified asset for the lease term. Leases will be classified as either financing or operating, with classification affecting the pattern of
expense recognition in the income statement. The new standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2018. A
modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period
presented in the consolidated financial statements, with certain practical expedients available. The Company will adopt ASC 842 effective January 1, 2019 using the modified
retrospective transition approach and intends to elect the package of practical expedients provided for under ASU 2018-11, Leases (Topic 842): Targeted Improvements, has
completed its review of all lease contracts that were in place as of December 31, 2018, and is finalizing the calculations of the right-of-use assets and related disclosures. Based
upon  the  preliminary  assessment  of  the  Company’s  leases,  adoption  of ASC  842  is  not  expected  to  have  a  material  impact  on  the  Company’s  consolidated  statements  of
operations, its consolidated statements of cash flows or its opening equity as of January 1, 2019, the effective date. The Company estimates that adoption of the new standard
will result in a gross-up on its consolidated balance sheets of approximately $830,000 relating to operating leases held for office space and laboratory facilities. Additionally, the
Company will reclassify the carrying value of the capital leases on laboratory equipment of approximately $341,000, which was reported as part of property and equipment and
capital  lease  obligations  in  the  consolidated  balance  sheet  as  of  December  31,  2018,  to  right  of  use  asset  and  finance  lease  liability,  in  accordance  with ASC  842.  Our
conclusions  are  preliminary  and  subject  to  change  as  we  finalize  our  analysis.  Changes  in  our  lease  population  or  changes  in  incremental  borrowing  rates  may  alter  these
estimates. We will expand our consolidated financial statements disclosure upon adoption of the new standard.

In August  2018,  the  FASB  issued ASU  2018-13,  Fair  Value  Measurement  (Topic  820):  Disclosure  Framework—Changes  to  the  Disclosure  Requirements  for  Fair  Value
Measurement. This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements as part of its disclosure framework project. The standard is
effective  for  all  entities  for  financial  statements  issued  for  fiscal  years  beginning  after  December  15,  2019,  and  interim  periods  within  those  fiscal  years.  Early  adoption  is
permitted. The Company is currently assessing this ASU and has not yet determined the impact ASU 2018-13 may have on its consolidated financial statements.

Other recent authoritative guidance issued by the FASB (including technical corrections to the ASC), the American Institute of Certified Public Accountants, and the Securities
and Exchange Commission (“SEC”) did not, or are not expected to, have a material impact on the Company’s consolidated financial statements and related disclosures.

4. Mortgage Note Receivable

In June 2014, the Company acquired a mortgage note from a bank for approximately $2,626,000 which was collateralized by, among other things, the underlying real estate and
related improvements. The property subject to the mortgage was owned by an entity managed by Daniel Fisher, one of the founders of Biozone, the property was also under
lease to MusclePharm. The mortgage note had an original maturity date of August 1, 2032 and bore an interest rate of 7.24%.

Shortly  thereafter  in  2014,  Daniel  Fisher  and  his  affiliate,  580  Garcia  Properties  LLC  (the  primary  obligor  of  the  note),  brought  multiple  lawsuits  against  the  Company
involving its predecessors and subsidiaries. The lawsuits were later settled and the complaints dismissed, without the Company making any payments to either Mr. Fisher or 580
Garcia Properties LLC. At the time of the note’s acquisition, 580 Garcia Properties LLC was delinquent in its obligation to make monthly payments. In December 2015, the
Company proceeded in accordance with rights of a secured real estate creditor under California law, to initiate private foreclosure proceedings. During 2017, the court enjoined
the Company from proceeding with the foreclosure sale pending further developments in the litigation.

In February 2018, the Company, Daniel Fisher, and 580 Garcia Properties LLC resolved all outstanding claims and disputes. As part of this settlement, the Company received a
payment of $1,400,000 in exchange for the release of the mortgage  note  and  deed  of  trust,  resulting  in  a  net  gain  of  $106,000  for  disposal  of  the  mortgage  note  receivable
reflected in the consolidated statement of operations for the year ended December 31, 2018.

7. Common Stock

As of December 31, 2018, the Company has authorized 100,000,000 shares of common stock, $0.001 par value per share. The Company had 29,938,363 and 24,274,494 shares
issued and outstanding as of December 31, 2018 and 2017, respectively.

The holders of common stock are entitled to one vote for each share of common stock held.

On April 20, 2017, the Company closed on proceeds of $3,000,000 in a private placement offering of 416,667 shares of the Company’s common stock at a purchase price of
$7.20 per share to three investors, which included our former Chairman Dr. Raymond F. Schinazi and OPKO Health, Inc., of which the Company’s director, Dr. Phillip Frost, is
Chairman and Chief Executive Officer.

On January 18, 2018, the Board of Directors of the Company filed an amendment (the “Amendment”) with the Delaware Secretary of State to effect a one-for-thirty reverse
split of the Company’s common stock. The Amendment took effect on January 24, 2018. No fractional shares were issued or distributed as a result of the Amendment. There
was no change in the par value of our common stock.

I n May  2018,  the  Company  closed  a  public  offering  for  gross  proceeds  and  net  proceeds  (inclusive  of  the  additional  proceeds  from  the  underwriter  exercised  from  the
overallotment options) of approximately $8,428,000 and $7,684,000, respectively. The Company sold 4,210,527 shares of common stock to the underwriter at approximately
$1.767 per share, which the underwriter sold to the public at $1.90 per share and issued the underwriter a warrant to purchase 84,211 shares of common stock at $2.09 per share
over a four-year period beginning October 27, 2018. On May 14, 2018, the underwriter exercised the option to purchase an additional 225,000 shares of common stock at $1.90
per share for additional gross proceeds and net proceeds of approximately $428,000 and $418,000, respectively, solely to cover overallotments. As of December 31, 2018, the
underwriter has no further option to purchase additional shares.

On May 21, 2018, the Company issued a total of 1,085,105 shares of common stock upon conversion of all outstanding 8% convertible notes. See Note 8 – Convertible Notes
Payable.

On August  6,  2018,  the  Company  held  its  2018 Annual  Meeting  of  Shareholders  and  voted  to  reduce  the  number  of  shares  of  common  stock,  $0.001  par  value  per  share,
authorized from 800,000,000 to 100,000,000 shares.

8. Convertible Notes Payable

On November 24, 2017 and January 31, 2018, the Company entered into securities purchase agreements with two investors, including the Company’s former Chairman of the
Board, pursuant to which the company sold an aggregate principal of $1,000,000, and OPKO Health Inc., a related party, (collectively, the “Purchasers”), pursuant to which the
Company sold an additional $1,000,000, of its 8% convertible notes (collectively, “Convertible Notes”) due on November 24, 2019 and January 31, 2020, respectively.

The Convertible Notes, with accrued interest, were convertible into common stock for $8.10 per share at the option of the Purchasers. In the event the Company completed a
financing in which the Company received at least $10,000,000 in gross proceeds and issued common stock or common stock equivalents to the investor (a “Financing”) or there
is a change of control of the Company (or sale of substantially all of the Company’s assets), the outstanding principal amount of the Convertible Notes would automatically
convert. Upon the closing of a Financing, the conversion price of the Convertible Notes shall be the lesser of (i) $8.10 per share or (ii) the price per share of the securities sold
in the Financing.

The  Company  evaluated  the  embedded  conversion  features  within  the  Convertible  Notes  under ASC  815-15  and ASC  815-40  to  determine  if  they  required  bifurcation  as  a
derivative instrument. The Company determined the embedded conversion features do not meet the definition of a derivative liability, and therefore, do not require bifurcation
from the host instrument. In addition, the down-round provision under which the conversion price could be affected by future equity offerings, qualified for a scope exception
from derivative accounting with the Company’s early adoption of ASU 2017-11,  Simplifying Accounting for Certain Financial Instruments with Characteristics of Liabilities
and Equity, during the year ended December 31, 2017. Since the embedded conversion features were not considered derivatives, the convertible notes were accounted for in
accordance with ASC 470-20, Debt with Conversion and Other Options.

In May 2018, the Company completed a financing and issued a total of 4,435,527 shares of common stock at $1.90 per share, for gross proceeds and net proceeds of $8,428,000
and $7,680,000, respectively. Although the total gross financing amount did not contractually effectuate the conversion feature of the Convertible Notes’ securities purchase
agreements, the Company allowed Purchasers to convert the Convertible Notes to common stock at the $1.90 per share price of the May 2018 financing. All outstanding 8%
convertible notes were converted to shares of common stock in May 2018 at the aggregate amount of the principal and accrued interest of for approximates $2,062,000 as of the
date of conversion, for a total of 1,085,105 common shares issued. The conversion was approved by disinterested members of the Company’s Board of Directors.

9. Stock Based Awards

Equity Incentive Plans

The Company adopted an equity incentive plan in 2007 (the “2007 Plan”) under which 1,786,635 shares of common stock have been reserved for issuance to employees and
nonemployee directors and consultants of the Company. Recipients of incentive stock options granted under the 2007 Plan shall be eligible to purchase shares of the Company’s
common stock at an exercise price equal to no less than the fair market value of such stock on the date of grant. The maximum term of options granted under the 2007 Plan is
ten  years.  The  options  generally  vest  25%  after  one  year,  with  the  remaining  balance  vesting  monthly  over  the  following  three  years. As  of  December  31,  2018,  189,894
options remain available for future grant under this plan.

The Company adopted a second equity incentive plan in 2015 (the “2015 Plan”) under which 1,666,667 shares of common stock have been reserved for issuance to employees,

Company’s common stock at an exercise price equal to no less than the estimated fair market value of such stock on the date of grant. The maximum term of options granted
under the 2015 Plan is ten years. The options generally vest 25% after one year, with the remaining balance vesting monthly over the following three years. As of December 31,
2018, 683,333 options remain available for future grant under the 2015 Plan.

The Company accounts for share-based awards to employees and nonemployees directors and consultants in accordance with the provisions of ASC 718, Compensation—Stock
Compensation., and under the recently issued guidance following FASB’s pronouncement, ASU 2018-07,  Compensation—Stock Compensation (Topic 718): Improvements to
Nonemployee Share-Based Payment Accounting. Under ASC 718, and applicable updates adopted, share-based awards are valued at fair value on the date of grant and that fair
value  is  recognized  over  the  requisite  service,  or  vesting,  period.  The  Company  values  its  equity  awards  using  the  Black-Scholes  option  pricing  model,  and  accounts  for
forfeitures when they occur. For the years ended December 31, 2018 and 2017, equity-based compensation expense recorded was $562,000 and $614,000, respectively.

As  of  December  31,  2018,  there  was  $1,933,000  of  total  unrecognized  compensation  expense  related  to  non-vested  stock  options  that  is  expected  to  be  recognized  over  a
weighted  average  period  of  1.9  years.  For  options  granted  and  outstanding,  there  were  1,351,096  options  outstanding  which  were  fully  vested  or  expected  to  vest,  with  an
aggregate intrinsic value of $788,000, a weighted average exercise price of $5.73, and weighted average remaining contractual term of 7.5 years at December 31, 2018. For
vested and exercisable options, outstanding shares totaled 411,511, with an aggregate intrinsic value of $29,000. These options had a weighted-average exercise price of $11.32
per share and a weighted-average remaining contractual term of 2.5 years at December 31, 2018.

The  aggregate  intrinsic  value  of  outstanding  and  exercisable  options  at  December  31,  2018  was  calculated  based  on  the  closing  price  of  the  Company’s  common  stock  as
reported on the Nasdaq Capital Market on December 31, 2018 of approximately $3.60 per share less the exercise price of the options. The aggregate intrinsic value is calculated
based on the positive difference between the closing fair market value of the Company’s common stock and the exercise price of the underlying options.

Warrants consist of equity-classified warrants and warrants with the potential to be settled in cash, which are liability-classified warrants. As of December 31, 2018, 159,164
warrants are accounted for as liabilities and 84,211 warrants are accounted for as equity.

Warrants Classified as Equity

Equity-classified warrants consist of stand-alone warrants with rights to buy shares of the Company at a pre-designated price on or before the date of expiration, irrespective of
the market price. These purchase warrants are not attached to any debt or equity instruments, thus considered freestanding, and there are no circumstances under ASC 815 that
require the warrants to be classified as liabilities or as derivatives. Thus, our May 2018 warrants will be classified as equity, and their value will be carried in the additional paid-
in capital account in the stockholders’ equity section of the balance sheet.

These warrants were granted to the underwriters and investment brokers for services provided related to the Company’s May 2018 equity financing, and collectively grant the
right to buy 84,211 shares of our stock at $2.09 per share for up to four years until expiration from the commencement date of October 27, 2018.

Warrants Classified as Liabilities

Liability-classified  warrants  consist  of  warrants  issued  by  Biozone  in  connection  with  equity  financings  in  October  2013  and  January  2014,  which  were  assumed  by  the
Company in connection with its merger with Biozone in January 2014. Warrants accounted for as liabilities have the potential to be settled in cash or are not indexed to the
Company’s own stock.

The estimated fair value of outstanding warrants accounted for as liabilities is determined at each balance sheet date. Any decrease or increase in the estimated fair value of the
warrant liability since the most recent balance sheet date is recorded in the consolidated statement of operations as changes in fair value of derivative liabilities. The fair value of
the warrants classified as liabilities is estimated using the Black-Scholes option-pricing model with the following inputs as of December 31, 2018:

Strike price
Expected dividend yield
Expected term (years)
Cumulative volatility
Risk-free rate

The Company estimates volatility using a blend of its own historical stock price volatility as well as that of market comparable entities since the Company’s common stock has
limited trading history and limited observable volatility of its own. The expected life assumption is based on the remaining contractual terms of the warrants. The risk-free rate
is based on the zero coupon rates in effect at the balance sheet date. The dividend yield used in the pricing model is zero, because the Company has no present intention to pay
cash dividends.

11. Licenses and Collaborations

Emory University

On December 6, 2018, we notified Emory University (“Emory”) of the termination of our License Agreement with Emory, dated March 7, 2013 (the “License Agreement”).
Pursuant  to  the  License Agreement,  Emory  agreed  to  add  to  the  Licensed  Patents  and  Licensed  Technology  Emory’s  rights  to  any  patent,  patent  application,  invention,  or
technology application that was based on technology disclosed within three (3) years of March 7, 2013. The License Agreement included payments due to Emory ranging from
$40,000 to $500,000 based on successful achievement of certain drug development milestones. Additionally, Cocrystal undertook to make royalty payments at 3.5% of net sales
due to Emory with a minimum in year one of $25,000 and increase to $400,000 in year five upon product commercialization.

The License Agreement covered patents and patent applications for hepatitis C virus (“HCV”) inhibitors, which we no longer consider essential to our HCV program. As part of
our HCV program, we continue to focus our efforts on CC-31244, our HCV Non-Nucleoside Polymerase Inhibitor, in Phase 2a clinical trial. The Company had the right to
terminate the License Agreement at its sole discretion upon a 90 days’ prior written notice and upon payment of all amounts due Emory under the License Agreement through
the date of termination. No amounts are due under the License Agreement.

Merck Sharp & Dohme Corp.

On January 2, 2019, the Company entered into an Exclusive License and Research Collaboration Agreement (the “Collaboration Agreement”) with Merck Sharp & Dohme
Corp. (“Merck”) to discover and develop certain proprietary influenza A/B antiviral agents. Under the terms of the Collaboration Agreement, Merck will fund research and
development  for  the  program,  including  clinical  development,  and  will  be  responsible  for  worldwide  commercialization  of  any  products  derived  from  the  collaboration.
Cocrystal received an upfront payment of $4 million and is eligible to receive payments related to designated development, regulatory and sales milestones with the potential to
earn  up  to  $156,000,000,  as  well  as  royalties  on  product  sales.  Merck  can  terminate  the  Collaboration Agreement  at  any  time  prior  to  the  first  commercial  sale  of  the  first
product developed under the Collaboration Agreement, in its sole discretion, without cause.

National Institute of Health

Cocrystal has two Public Health Biological Materials License Agreements with the National Institute of Health. The original License Agreements were dated August 31, 2010
and amended on November 6, 2013. The materials licensed are being used in Norovirus assays to screen potential antiviral agents in our library.

Duke University and Emory University

In  February  2016,  the  Company  entered  into  an  agreement  with  Duke  University  and  Emory  University  to  license  various  patents  and  know-how  to  use  CRISPR/Cas9
technologies  for  developing  a  possible  cure  for  hepatitis  B  virus  (HBV)  and  human  papilloma  virus  (HPV).  On  September  25,  2017  (“Termination  Date”),  the  Company
mutually terminated the agreement with Duke University and Emory University, there are no further rights or obligations under this license agreement after the termination date.

12. Net Loss per Share

The  Company  accounts  for  and  discloses  net  loss  per  common  share  in  accordance  with  FASB ASC  Topic  260, Earnings  Per  Share.  Basic  net  loss  per  common  share  is
computed  by  dividing  net  loss  attributable  to  common  stockholders  by  the  weighted  average  number  of  common  shares  outstanding.  Diluted  net  loss  per  common  share  is
computed by dividing net loss attributable to common stockholders by the weighted average number of common shares that would have been outstanding during the period
assuming the issuance of common stock for all potential dilutive common shares outstanding. Potential common shares consist of shares issuable upon the exercise of stock
options and warrants and the conversion of convertible notes payable.

In accordance with the authoritative guidance for income taxes under ASC 740, a deferred tax asset or liability is determined based on the difference between the financial
statement  and  the  tax  basis  of  assets  and  liabilities  as  measured  by  the  enacted  tax  rates,  which  will  be  in  effect  when  these  differences  reverse.  The  Company  provides  a
valuation allowance against net deferred tax assets unless, based upon the available evidence, it is more likely than not that the deferred tax assets will be realized.

The Company recognizes the impact of a tax position in the consolidated financial statements only if that position is more likely than not of being sustained upon examination
by taxing authorities, based on the technical merits of the position. The Company’s practice is to recognize interest and/or penalties related to income tax matters as income tax
expense. At December 31, 2018, there are no unrecognized tax benefits nor any significant accruals for interest related to unrecognized tax benefits or tax penalties.

The  Company  is  subject  to  taxation  and  files  income  tax  returns  in  the  United  States  and  various  state  jurisdictions. All  tax  years  from  inception  to  date  are  subject  to
examination by the U.S. and state tax authorities due to the carry-forward of unutilized net operating losses and research and development credits. Currently, no years are under
examination.

Balances of deferred tax assets as of December 31, 2018 and 2017, include the following, respectively:

(i) California net operating loss carryforwards of $1,190,000 and $1,115,000,
(ii) Georgia net operating loss carry forwards of $543,000 and $941,000,
(iii) California research and development tax credits of $203,000 and $203,000.

The impairment of certain indefinite lived intangibles generated an income tax benefit of $13,582,000 for the year ended December 31, 2018. After December 31, 2018, the
Company does not expect any additional tax expense or tax benefit related to the fully impaired indefinite lived intangibles.

The Company has established a valuation allowance against net deferred tax assets due to the uncertainty that such assets will be realized. The Company periodically evaluates
the recoverability of the deferred tax assets. At such time as it is determined that it is more likely than not that deferred tax assets will be realizable, the valuation allowance will
be reduced.

Certain amounts included in the Company’s gross deferred tax assets as of December 31, 2018, and specifically detailed under (i) – (iii) in the table above, are recoverable only
if  the  Company  generates  taxable  income  in  states  that  it  no  longer  maintains  operations,  Georgia  and  California.  Due  to  the  Company’s  present  stage  of  development,  the
proximity of those states to Florida and Washington where offices are currently located, and the ongoing, existing and potential strategic business relationships within those
states considered significant to the Company and its related parties, the Company does not believe recoverability of the Georgia or California deferred tax assets recognized to
be more remote than its other federal and state deferred tax assets, nor require additional reserves, at this time. As such, those, and all of the Company’s deferred tax assets,
have been reported at gross amounts within Note 13 hereto, and are subject to a full valuation allowance.

At  December  31,  2018,  the  Company  has  federal  and  state  net  operating  losses,  or  NOL,  carryforwards  of  approximately  $70,468,000  and  $30,907,000,  respectively.  The
federal  NOL  carryforwards  begin  to  expire  in  2026,  and  the  state  NOL  carryforwards  begin  to  expire  in  2028.  The  federal  loss  generated  in  2018  of  $8,829,000  will  carry
forward indefinitely and be available to offset up to 80% of future taxable income each year.

At December 31, 2018, the Company had federal and state capital loss carryforwards of approximately $1,071,000 that expire in 2023.

At  December  31,  2018,  the  Company  also  had  federal  and  California  research  and  development  tax  credit  carryforwards  of  approximately  $1,820,000  and  $257,000,
respectively. The federal research and development tax credit carryforwards begin to expire in 2028, and the California research and development tax credit carryforwards do
not expire and can be carried forward indefinitely until utilized. The Company has not completed a formal research and development (“R&D”) tax credit study for any of the
years the credits were generated. The IRC 41 credit may be subject to change if audited by the IRS. Any changes to the credit would also result in a change in the valuation
allowance against the federal and state deferred tax asset associated with R&D tax credits.

The above NOL carryforwards and the research tax credit carryforwards may be subject to an annual limitation under Section 382 and 383 of the Internal Revenue Code of
1986, and similar state provisions if the Company experienced one or more ownership changes, which would limit the amount of NOL and tax credit carryforwards that can be
utilized  to  offset  future  taxable  income  and  tax,  respectively.  In  general,  an  ownership  change,  as  defined  by  Section  382  and  383,  results  from  transactions  increasing
ownership of certain stockholders or public groups in the stock of the corporation by more than 50 percentage points over a three-year period. The Company has not completed
an IRC Section 382/383 analysis. If a change in ownership were to have occurred, NOL and tax credits carryforwards could be eliminated or restricted. If eliminated, the related
asset would be removed from the deferred tax asset schedule with a corresponding reduction in the valuation allowance.

In  2017,  the  Company  adopted  ASU  2016-09, Compensation  -  Stock  Compensation.  The  Company  has  excess  tax  benefits  for  which  a  benefit  could  not  previously  be
recognized of approximately $13,000. The balance of the unrecognized excess tax benefits has been reversed with the impact recorded to retained earnings including any change
to the valuation allowance as a result of the adoption in 2017. Due to the full valuation allowance on the U.S. deferred tax assets, there is no impact to the financial statements as
a result of this adoption.

A reconciliation of the federal statutory income tax rate to the Company’s effective income tax rate for the years ended December 31, 2018 and 2017 is as follows:

Statutory federal income tax rate
Change in fair value of warrant liability
State income taxes, net of federal benefit

Change in valuation allowance

In December 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted. The 2017 Tax Act includes a number of changes to existing U.S. tax laws that impact the
Company, most notably a reduction of the U.S. corporate income tax rate from 35 percent to 21 percent for tax years beginning after December 31, 2017. The 2017 Tax Act also
provides for the acceleration of depreciation for certain assets placed in service after September 27, 2017, as well as prospective changes beginning in 2018, including additional
limitations on executive compensation, on the deductibility of interest, and on capitalization of research and development expenditures.

In December 2017, the SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the income tax effects of the 2017 Tax Act.
SAB 118 provides a measurement period that should not extend beyond one year from the 2017 Tax Act enactment date for companies to complete the accounting relating to
the 2017 Tax Act under Accounting Standards Codification Topic 740,  Income Taxes (“ASC 740”). In accordance with SAB 118, an entity must reflect the income tax effects
of those aspects of the 2017 Tax Act for which the accounting under ASC 740 is complete. To the extent that an entity’s accounting for 2017 Tax Act related income tax effects

The Company measures deferred tax assets and liabilities using enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered or
paid. Accordingly, as of December 31, 2017, the Company’s deferred tax assets and liabilities were remeasured to reflect the provisions of the 2017 Tax Act and reduction in
the U.S. corporate income tax rate from the highest graduated tax of 35 percent to a 21 percent flat tax. The initial remeasurement of deferred tax liabilities that were related to
indefinite-lived intangibles generated an income tax benefit of $6,587,000, as well as an additional $293,000 tax benefit as a result of projected NOLs expected to be generated
in 2018 and beyond that have an indefinite life under the  2017  Tax Act,  for  a  total  tax  benefit  of  $6,880,000  reflected  in  the  2017  consolidated  statement  of  operations.  In
addition,  as  of  December  31,  2017,  the  initial  remeasurement  of  the  deferred  tax  assets  and  liabilities  that  are  not  associated  with  indefinite-lived  intangibles  generated  an
income tax expense of approximately $8,282,000, which reduced the Company’s gross deferred tax assets, but was entirely offset by the Company’s full valuation allowance.
The Company completed its evaluation of the potential impacts of the 2017 Tax Act on its 2018 consolidated financial statements and concluded to have no further impact as of
December 31, 2018.

14. Commitments and Contingencies

Commitments

In  the  ordinary  course  of  business,  the  Company  enters  into  non-cancelable  leases  for  its  facilities,  including  related  party  leases  (see  Note  15  –  Transactions  with  Related
Parties), and to purchase equipment. As per Note 2, leases are accounted for as operating leases or capital leases, in accordance with ASC 840, Leases.

Operating Leases

The Company leases office space in Miami, Florida and laboratory space in Bothell, Washington under operating leases that expire on August 31, 2021 and January 31, 2024,
respectively. The Company recently signed an amendment to the Bothell, Washington lease agreement by extending the lease term for a period of sixty months from, February
2019 through January 2024. Future minimum operating lease payments, by year and in aggregate, are as follows:

Year ending December 31,
2019

2023 and thereafter
Total minimum operating lease payments

The minimum lease payments above do not include common area maintenance (CAM) charges, which are contractual obligations under the Company’s Bothell, Washington
lease, but are not fixed and can fluctuate from year to year. CAM charges for the Bothell, Washington facility are calculated and billed based on total common expenses for the
building incurred by the lessor and apportioned to tenants based on square footage. In 2018 and 2017, approximately $71,000 and $69,000 of CAM charges for the Bothell,
Washington lease were included in operating expenses in the consolidated statements of operations, respectively.

The minimum lease payments above include the amounts that would be paid if the Company maintains its Bothell lease for the five-year term, starting February 2019. The
Company has the right to terminate this lease after three years on January 31, 2022, by giving prior notice at least nine months before the early termination date and by paying a
termination fee equal to the sum of unamortized leasing commissions and reimbursement for tenant improvements provided by the landlord amortized at 8% over the extended
term.

On September 1, 2018, the Company entered into a lease agreement with a limited liability company controlled by Dr. Phillip Frost, a director and a principal shareholder of the
Company  (see  Note  15  –  Transactions  with  Related  Parties).  The  lease  term  is  three  years  with  an  optional  three-year  extension.  On  an  annualized  basis,  rent  expense  is
approximately $49,000. The minimum lease payments above do not include taxes and fees, which are expected to be approximately $9,000, annually.

The offices and laboratory space in Tucker, Georgia were leased from a limited liability company owned by one of Cocrystal’s former directors, Dr. Raymond Schinazi and
previously leased on a month to month basis (see Note 15 – Transactions with Related Parties). The Company closed its office in Tucker, Georgia, and the last lease payment
was made in October 2018.

Rent expense, excluding capital leases and CAM charges, for 2018 and 2017 totaled $187,000 and $293,000, respectively.

Capital Leases

In November 2018, the Company entered into two lease agreements to acquire equipment with 18 monthly payments of $18,000 payable through May 27, 2020 and 36 monthly
payments of $1,000 payable through November 21, 2021. The lease agreements have an effective interest rate of 8.01%.

Future minimum capital lease payments, by year and in aggregate, are as follows:

The leased lab equipment is included under property and equipment and depreciable over five years. Total assets and accumulated depreciation recognized, net, under capital
leases was $347,000 and $6,000 for the year ended December, 31, 2018, respectively. The Company had no leases considered to be capital leases as of December 31, 2017.

At December 31, 2018, the aggregate outstanding balance of the capital lease obligations is $331,000 and the Company expects to pay future interest charges of $22,000 over
the remaining capital lease terms. In 2018, the Company paid $16,000 and $3,000 in principal and interest related to capital leases, respectively.

Contingencies

From  time  to  time,  the  Company  is  a  party  to,  or  otherwise  involved  in,  legal  proceedings  arising  in  the  normal  course  of  business. As  of  the  date  of  this  report,  except  as
described below, the Company is not aware of any proceedings, threatened or pending, against it which, if determined adversely, would have a material effect on its business,
results of operations, cash flows or financial position.

On September 20, 2018, Anthony Pepe, individually and on behalf of a class, filed with the United States District Court for the District of New Jersey a complaint against the
Company, certain current and former executive officers and directors of the Company and the other defendants named therein for violation of Section 10(b) of the Exchange Act
and Rule 10b-5 promulgated thereunder. The class consists of the persons and entities who purchased the Company’s common stock during the period from September 23, 2013
through September 7, 2018. Pepe also alleges violation of other sections of the Exchange Act by the defendants named in the complaint other than the Company. Pepe seeks
damages, pre-judgment and post-judgment interest, reasonable attorneys’ fees, expert fees and other costs.

On January 16, 2019, Ms. Susan Church, a stockholder of the Company, filed with the United States District Court for the Western District of Washington a derivative suit
against  certain  current  and  former  executive  officers  and  directors  of  the  Company  alleging  breach  of  fiduciary  duties,  unjust  enrichment,  waste  of  corporate  assets,  and
violations of the rules governing proxy solicitation. Church seeks, among other things, money damages, disgorgement of profits from alleged wrongful conduct, including cash
bonuses, pre-judgment and post-judgment interest, reasonable attorneys’ fees, expert fees and other costs.

On September 7, 2018, the SEC filed with the United States District Court for the Southern District of New York a complaint against Dr. Philip Frost, a director and principal
stockholder of the Company, a trust Dr. Frost controls and OPKO Health, Inc., a stockholder of the Company, of which Dr. Frost is the Chief Executive Officer, as well as other
defendants  named  therein.  On  January  10,  2019,  the  District  Court  entered  final  judgments  against  these  defendants  on  their  consent  without  admitting  or  denying  the
allegations set forth in the complaint. Dr. Frost was permanently enjoined from violating a certain anti-fraud provision of the Securities Act of 1933, future violations of Section
13(d) of the Exchange Act and Rule 13d-1(a) thereunder, and participating in penny stock offerings subject to certain exceptions.

In November 2017, Lee Pederson, a former Biozone lawyer, filed a lawsuit in Minnesota against co-defendants the Company, Dr. Phillip Frost, OPKO Heath, Inc. and Brian
Keller for various allegations. On September 13, 2018, the United States District Court granted the Company and its co-defendants’ motion to dismiss Pederson’s amended
complaint. Subsequent to September 30, 2018, Pederson has filed a notice of appeal with the United States Court of Appeals for the Eighth Circuit on October 11, 2018.

While  the  Company  intends  to  defend  itself  vigorously  from  the  claims  in  the  aforementioned  disputes,  it  is  unable  to  predict  the  outcome  of  these  legal  proceedings. Any
potential loss as a result of these legal proceedings cannot be reasonably estimated. As a result, the Company has not recorded a loss contingency for any of the aforementioned
claims.

15. Transactions with Related Parties

Beginning November 2014 to October 2018, the Company leased its Tucker, Georgia facility from a limited liability company owned by one of Cocrystal’s former directors
and principal shareholder, Dr. Raymond Schinazi. As of October 2018, the Company cancelled the leasing arrangement and closed its office in Tucker, Georgia. Total rent and
other expenses paid in connection with this lease was $77,000 and $242,000 for the years ended December 31, 2018 and 2017, respectively.

In September 2018, the Company leased administrative offices from a limited liability company owned by one of the Company’s directors and principal shareholder, Dr. Phillip
Frost.  The  lease  term  is  three  years  with  an  optional  three-year  extension.  On  an  annualized  basis,  rent  expense,  including  taxes  and  fees,  for  this  location  would  be
approximately  $58,000.  The  Company  paid  a  lease  deposit  of  $4,000  and  total  rent  and  other  expenses  paid  in  connection  with  this  lease  was  $19,000  for  the  year  ended
December 31, 2018.

As further explained in Note 8 – Convertible Notes Payable, on November 24, 2017, the Company entered into a securities purchase agreement with a company significantly
owned  by  the  Company’s  former  Chairman  of  the  Board,  Dr.  Schinazi,  pursuant  to  which  the  Company  sold  a  principal  amount  of  $500,000  of  8%  convertible  notes  due
November 24, 2019. On January 31, 2018, the Company entered into a securities purchase agreement with OPKO Health, Inc. (the “Purchaser”), a Company affiliated with Dr.
Frost, pursuant to which the Company borrowed $1,000,000 from the Purchaser in exchange for issuing the Purchaser an 8% convertible note due January 31, 2020.

All  8%  convertible  notes,  including  accrued  interest,  were  converted  to  common  stock  shares  in  May  2018  at  $1.90  per  share.  Dr.  Schinazi’s  affiliated  Company  received
273,367 shares for its 8% convertible notes balance of approximately $519,000, and OPKO Health, Inc., affiliated with Dr. Frost, received 538,544 shares for its 8% convertible
notes balance of approximately $1,023,000 upon conversion. In the consolidated balance sheets, as of December 31, 2018 and 2017, approximately $0 and $504,000 included in
convertible notes payable were amounts due to related parties.

16. Subsequent Events

Merck Collaboration

On  January  2,  2019,  we  entered  into  an  Exclusive  License  and  Research  Collaboration Agreement  (the  “Collaboration Agreement”)  with  Merck  Sharp  &  Dohme  Corp.
(“Merck”)  to  discover  and  develop  certain  proprietary  influenza  A/B  antiviral  agents.  Under  the  terms  of  the  Collaboration  Agreement,  Merck  will  fund  research  and
development for the program, including clinical development, and will be solely responsible for worldwide commercialization of any products derived from the collaboration.
We  received  an  upfront  payment  of  $4,000,000  and  are  eligible  to  receive  milestone  payments  related  to  designated  development,  regulatory  and  sales  milestones  with  the
potential to receive up to $156,000,000, as well as royalties on product sales. The Collaboration Agreement contains certain termination provisions that can be invoked by either
party.

Private Placement

On March 13, 2019, the Company closed a private placement of 1,602,283 shares of its common stock and received gross proceeds of $4,182,000, before deducting offering
expenses and commissions, and net proceeds were approximately $3,674,000.

At-the-Market Sales

On March 20, 2019, the Company by written notice suspended at-the-market sales of its common stock pursuant to the Distribution Agreement, dated July 19, 2018 by and
among  the  Company,  Ladenburg,  Barrington,  and AGP.  The  Company  also  terminated  the  engagement  of  Barrington  as  a  sales  agent  under  the  Distribution Agreement
effective March 21, 2019. The Distribution Agreement remains in place with respect to AGP, subject to the suspension of sales discussed above until further notice is provided
by the Company to AGP. In January 2019, we sold 80,000 shares of common stock under the Distribution Agreement and received net proceeds of approximately $344,000.

in accordance with Schedule 2.1 and the terms and conditions of this Agreement.

  2.5

[*].

  2.6

Joint Research Committee. The Parties hereby establish a committee to facilitate the Research Program as follows:

2.6.1

2.6.2

Composition of  the  Joint  Research  Committee.  The  Research  Program  shall  be  conducted  under  the  direction  of  a  joint  research  committee (the
“Committee”) comprised of three (3) representatives of Merck (who shall be employees of Merck or its Affiliate, as applicable) and three (3) representatives of
Cocrystal  (who shall be employees of Cocrystal or its Affiliate, as applicable). A list of initial representatives of Merck and Cocrystal  are attached hereto as
Schedule 2.6.1. Each Party may change its representatives to the Committee from time to time in its sole discretion, effective upon notice to the other Party of
such change. These representatives shall have appropriate technical credentials, experience and knowledge, and ongoing familiarity with the Research Program.
Additional representative(s) or consultant(s) may from time to time, by mutual consent of the Parties, be invited to attend Committee meetings, subject to such
representative’s or consultant’s written agreement to comply with the requirements of Section 4.1. The Committee shall be chaired by a representative of Merck.
Decisions of the Committee shall be made unanimously by the representatives. In the event that the Committee cannot or does not, after reasonable good faith
efforts, reach agreement on an issue within [*] after such matter has been referred to the Committee, then the matter shall be [*].

Scope of Committee Oversight. The Committee shall be responsible for overseeing the Research Program, including to (i) review and amend the Research
Plan from time to time, (ii) review and coordinate the Parties’ activities under the Research Program, (iii) confer regarding the status of the Research Program
and the progress under the Research Program and to make determinations and decisions in connection with the activities under the Research Program (including
issues of priority), (iv) review relevant data under the Research Program, (v) consider and advise on any technical issues that arise under the Research Program,
and (vi) determine such other matters as allocated to the Committee hereunder. The Committee shall not have  the authority to: (w) modify or amend the terms
and conditions of this Agreement; (x) waive either Party’s compliance with the terms and conditions of this Agreement; (y) determine any issue in a manner that
would conflict with the express terms and conditions of this Agreement or (z) amend the Research Plan in a manner that would increase the financial or other
resource (i.e.,  FTEs)  obligations  imposed  on  Cocrystal  or  Merck  beyond  the  scope  of  those  required  under  the  then  current planned  activities,  and  if  such
amendment would increase such financial or other resource (i.e., FTEs) obligations, then such amendment must be mutually agreed to by the Parties in writing
(including  mutual  agreement  on  the  number  of  additional FTEs  of  Cocrystal  needed  to  perform  such  work  and  to  be  funded  by  Merck  in  accordance  with
Section 5.1); provided that, for the avoidance of doubt if the work proposed in the amendment to the Research Program activities could be performed by the
FTEs then currently being funded by Merck and such work would not impose additional financial obligations on Cocrystal beyond the then current Research
Program  activities,  Cocrystal  shall  perform  such  work  at  no  additional  charge  and  the  Research Program  activities  shall  automatically  be  deemed  to  be
amended to include such work as proposed by the Committee.

Each  Party  shall  promptly  disclose  to  the  other  Party  in  writing  the  development,  making,  conception  or  reduction  to  practice  of  Collaboration  Information  and
Inventions  and  all  Compounds.  Inventorship  of  Patent  Rights  shall  be  determined  in  accordance  with  United  States  patent  laws  (regardless  of  where  the  applicable
activities occurred). Subject to the licenses granted to the other Party under this Agreement and the other terms and conditions of this Agreement, each Party shall have
the  non-exclusive  right  to  exploit  its  interest  in  Collaboration  Information  and  Inventions  and  Collaboration  Patent  Rights,  and  to  grant  licenses  under  its  interest  in
Collaboration Information and Inventions and Collaboration Patent Rights, as it deems appropriate, without the consent of, and without accounting to, the other Party;
provided, however, that for clarity, the foregoing joint ownership rights shall not be construed as granting, conveying or creating any license or other rights to the other
Party’s intellectual property, unless otherwise expressly set forth in this Agreement; and  further provided that, in the event that any Collaboration Patent Rights claim or
cover a Compound or the manufacturing process therefor, Cocrystal shall not grant any license under its interest in such Collaboration Patent Rights to any Third Party

however, that Cocrystal shall not be obligated to perform any such work with or for the benefit of Merck during [*] unless [*] and (ii) shall not, and shall ensure that its
Affiliates and its licensees and sublicensees who have any use or other rights in or to Cocrystal Know-How or Cocrystal Patent  Rights  do  not,  directly  or  indirectly,
conduct, exploit, or fund any activity that involves the research and discovery efforts related to the Target, either alone or with a Third Party, regardless of whether the
collaborative work with Merck under the Research Plan is ongoing or has concluded. It is the desire and intent of the Parties that the restrictive covenants contained in
this  Section  2.13  (Exclusive  Efforts)  be  enforced  to  the  fullest  extent  permissible  under  applicable  laws,  rules, regulations,  and  public  policies  applied  in  each
jurisdiction in which enforcement is sought. Merck and Cocrystal believe that the restrictive covenants in this Section 2.13 are valid and enforceable. However, if any
restrictive covenant should for any reason become or be declared by a competent court or competition authority to be invalid or unenforceable in any jurisdiction, such
restrictive covenant shall be deemed to have been amended to the extent necessary in order that such provision be valid and  enforceable,  and  such  amendment  shall
apply only with respect to the operation of such provision of this Section 2.13 in the particular jurisdiction in which such declaration is made.

regulatory or legal requirements. Each Party hereby certifies that it has not in the past [*], and it will not, employ or otherwise use in any capacity the services
of any person or entity debarred under Section 21 USC 335a in performing any services hereunder. A Party shall notify the other Party in writing immediately
if any such debarment occurs or comes to its attention and shall promptly remove any person or entity so disbarred from performing any activities under the
Research Program or function or capacity related to the Research Program. [*]

2.14.2 Each Party acknowledges that Merck’s corporate policy requires that Merck’s business must be conducted within the letter  and spirit of the law. By signing this

Agreement, each Party agrees to conduct the services contemplated herein in a manner which is consistent with both law and good business ethics.

2.14.3

Specifically,  Cocrystal  warrants  that  none  of  its  current  employees,  agents,  officers  or  other  members  of  its  management  are  officials, officers,  agents,
representatives of any government or international public organization. Cocrystal shall not make any payment, either directly or indirectly, of money or other
assets, including but not limited to the compensation Cocrystal derives from this Agreement (hereinafter collectively referred as a “Payment”), to government
or political party officials, officials of international public organizations, candidates for public office, or representatives of other businesses or persons acting on

within [*] of the date Cocrystal delivers to Merck such accounting firm’s written report so correctly concluding, or as otherwise agreed upon by the Parties. The
fees charged by such accounting firm shall be paid by Cocrystal; provided, however,  that if such audit uncovers an underpayment of royalties by Merck that
exceeds the greater of [*] and [*] of the total royalties owed, then the fees of such accounting firm shall be paid by Merck.

5.6.3 Merck shall include in each sublicense granted by it pursuant to this Agreement a provision  requiring the sublicensee to make reports to Merck, to keep and
maintain  records  of  sales made  pursuant  to  such  sublicense  and  to  grant  access  to  such  records  by  Cocrystal’s independent  accountant  to  the  same  extent
required of Merck under this Agreement.

5.6.4

Upon the expiration of [*] following the end of any Calendar Year, the calculation of royalties  payable with respect to such Calendar Year shall be binding and

Cocrystal shall treat all financial information subject to review under this Section 5.6 or under any sublicense agreement in accordance with the confidentiality
and  non-use  provisions of  this Agreement,  and  shall  cause  its  accounting  firm  to  enter  into  an  acceptable  confidentiality agreement  with  Merck  and/or  its
Related Parties obligating it to retain all such information in confidence pursuant to such confidentiality agreement.

Payment Exchange Rate. All payments to be made by Merck to Cocrystal under this Agreement shall be made in United States dollars and may be paid  by bank wire
transfer in immediately available funds to such bank account in the United States as may be designated in writing by Cocrystal from time to time. In the case of sales
outside the United States, the rate of exchange to be used in computing the monthly amount of currency equivalent in United States dollars due Cocrystal shall be made
at the monthly rate of exchange utilized by Merck in its worldwide accounting system.

5.8 Tax Matters. Cocrystal shall be liable for all taxes based on, measured by, or calculated with respect to, income or profits of Cocrystal  (“Income Taxes”) imposed upon
any payments  made  by  Merck  to  Cocrystal  under  this Article  5  (“Agreement Payments”). If  applicable  laws,  rules  or  regulations  require  the  withholding  of  Income
Taxes, Merck  shall make such withholding payments as are required to be made from the Agreement Payment, shall subtract the amount thereof from the Agreement
Payments and shall pay over such amount withheld and deducted to the proper governmental authorities. Merck shall submit to Cocrystal appropriate proof of payment
of the withheld Income Taxes as well as the official receipts within a reasonable period of time following payment thereof. Merck shall provide Cocrystal reasonable
assistance  in  order  to  allow  Cocrystal  to  reduce  or mitigate  any  such  Income  Tax  withholding  to  the  extent  permitted  under  applicable  laws, including  to  obtain  the
benefit of any present or future treaty against double taxation which may apply to the Agreement Payments. [*]

thereto  or  that  imposes  any Liability  or  obligation  on  the  Indemnified  Party  without  the  prior  written  consent  of  the  Indemnified  Party,  which  shall  not be
unreasonably withheld or delayed.

Territory, after appropriate consultation with Cocrystal, the Cocrystal Patent Rights licensed to Merck under this Agreement. Merck shall give Cocrystal an
opportunity to review the text of any patent application before filing, shall consult with Cocrystal with respect thereto, and shall supply Cocrystal with a copy
of the application when filed and as filed, together with notice of its filing date and serial number. Merck shall keep Cocrystal promptly advised of the status of
Cocrystal  Patent  Rights  and,  upon  Cocrystal’s  request,  shall  provide  advance  copies  of  any  papers  related  to  the  prosecution  and  maintenance  of  Cocrystal
Patent Rights. Merck shall promptly give notice to Cocrystal of the grant, lapse, revocation, surrender, invalidation or abandonment of any Cocrystal Patent
Rights licensed to Merck for which Merck is responsible for the filing, prosecution and maintenance.

(b) Merck shall give notice to Cocrystal and the Committee of any desire to not file patent applications claiming Cocrystal Patent Rights or Cocrystal Know-
How or to cease prosecution and/or maintenance of Cocrystal Patent Rights on a country by country basis in the Territory. [*]

In addition to the foregoing, in the event Merck does not continue the prosecution or maintenance of the applicable Cocrystal Patent Rights, and such Cocrystal
Patent  Rights  have  been  published  by  a  patent  office,  Merck  shall  permit  Cocrystal  to  continue  the  prosecution  or  maintenance  of  the  applicable  patent
application or patent at its own expense and Merck shall execute documents in a timely manner as may be reasonably necessary to allow Cocrystal to continue
such prosecution or maintenance.

Collaboration Patent  Rights.  Merck  shall  have  the  first  right  to  file,  prosecute,  and  maintain  patents  and  patent  applications  claiming Collaboration
Information  and  Inventions.  Merck  shall  keep  Cocrystal  promptly  advised  of  the  status  of  any  actual  and  prospective patent  filings  and  upon  Cocrystal’s
request, shall provide advance copies of any papers related to the filing of Collaboration Information and Inventions and the prosecution and maintenance of
Collaboration Patent Rights. Merck shall give notice to Cocrystal of any desire to cease prosecution and/or maintenance of Collaboration Patent Rights on a
country-by-country basis in the Territory [*].

Patent Term Extension. The Parties shall cooperate fully with each other to provide necessary information and assistance, as the other Party may reasonably
request,  in  obtaining  patent  term  extension  or  supplemental  protection  certificates  or  their equivalents  in  any  country  in  the  Territory  where  applicable  to
Cocrystal Patent Rights and Collaboration Patent Rights. In the event that elections with respect to obtaining such patent term extension are to be made, Merck
shall have the right to make the election and Cocrystal agrees to abide by such election.

Other Cooperation.  The  Parties  agree  to  cooperate  fully  and  provide  any  information  and  assistance  that  either  may  reasonably request  for  the  filing,
prosecution and maintenance of Cocrystal Patent Rights and Collaboration Patent Rights. The Parties further agree to take reasonable actions to maximize the

prosecuting Party shall be responsible for payment of all costs and expenses related to such activities.

Inventor Remuneration.  Cocrystal  shall  comply  with  all  applicable  country-specific  inventor  remuneration  laws  and  regulations  associated with  Cocrystal
Patent Rights and Collaboration Patent Rights when inventor remuneration obligations are triggered by an employee or contractor of Cocrystal or its Affiliates,
or  a  Third  Party  acting  on  behalf  of  Cocrystal  or  its  Affiliates.  Merck  shall comply  with  all  applicable  country-specific  inventor  remuneration  laws  and
regulations associated with Cocrystal Patent Rights and Collaboration Patent Rights when inventor remuneration obligations are triggered by an employee or
contractor  of  Merck or  its  Affiliates,  or  a  Third  Party  acting  on  behalf  of  Merck  or  its  Affiliates.  For  clarity,  any  applicable  country-specific  inventor
remuneration paid by Merck or its Related Parties is not considered a payment subject to 5.4.5.

  7.2

Interference, Derivation, Opposition, Reexamination, Reissue, Supplemental Examination, Inter Partes Review and Post-Grant Review Proceedings.

7.2.1

7.2.2

Third Party Initiated Proceedings. Each Party shall, within [*] of learning of such event, inform the other Party of any request for, or filing or declaration of,
any  interference,  derivation  proceeding,  opposition,  reexamination  requested  by  a  Third Party, inter  partes  review,  post-grant  review  or  similar  contested
administrative  proceeding  involving  a  Third  Party relating  to  Cocrystal  Patent  Rights  or  Collaboration  Patent  Rights.  Merck  and  Cocrystal  shall  thereafter
consult and cooperate fully to determine a course of action with respect to any such proceeding. Merck shall have the first right to control such proceedings with
respect  to  Cocrystal  Patent  Rights  and  Collaboration  Patent  Rights,  and  Cocrystal  shall  have  the  right  to review and approve any submission to be made in
connection  with  such  proceeding,  which  approval  will  not  be  unreasonably  withheld or  delayed,  and  shall  be  provided  copies  of  all  documents  filed  in
connection with such proceedings. In the event that Merck chooses not to control such proceeding under this Section 7.2.1, and upon Merck’s written consent
with  respect  to  Collaboration Patent  Rights,  which  consent  shall  not  be  unreasonably  withheld  or  delayed,  Cocrystal  shall  have  the  right  to  control  such
proceeding.

Party Initiated  Proceedings.  Merck  shall  have  the  first  right,  at  its  expense,  to  initiate  a  reexamination,  supplemental  examination, reissue  or  similar
administrative proceeding relating to Cocrystal Patent Rights or Collaboration Patent Rights. Notwithstanding the foregoing, Merck shall not initiate any such
proceeding  without  the  prior  written  consent  of  Cocrystal,  which  consent shall  not  be  unreasonably  withheld  or  delayed.  Cocrystal  shall  have  the  right  to
review and approve any submission to be made in connection with such proceeding, which approval shall not be unreasonably withheld or delayed, and shall be
provided  copies of  all  documents  filed  in  connection  with  such  proceedings.  If  there  is  disagreement  regarding  whether  a  reexamination,  supplemental
examination,  reissue  or  similar  administrative  proceeding  relating  to  Cocrystal  Patent  Rights  or  Collaboration  Patent  Rights should  be  initiated,  such
disagreement shall be referred to the senior intellectual property officers of the Parties. In the event that these two executives do not, after reasonable good faith
efforts, reach agreement, the resolution and/or course of conduct shall be determined by Merck, in good faith, with respect to Collaborative Patent Rights. In the
event that Merck chooses not to initiate a proceeding under this Section 7.2.2, and upon Merck’s written consent with respect to Collaboration  Patent Rights,
which consent shall not be unreasonably withheld or delayed, Cocrystal shall have the right to initiate such proceedings. The initiating Party shall have the first
right to control such proceedings.

Enforcement and Defense.

7.3.1

The Parties shall give notice to each other of either (i) any infringement of Cocrystal Patent Rights or Collaboration Patent Rights, or (ii) any misappropriation
or misuse of Cocrystal Know-How or Collaboration Information and Inventions, that may come to its attention. Merck and Cocrystal shall thereafter consult
and cooperate fully to determine a course of action, including but not limited to the commencement of legal action by either or both Merck and Cocrystal, to
terminate  any  infringement  of Cocrystal  Patent  Rights  or  Collaboration  Patent  Rights  or  any  misappropriation  or  misuse  of  Cocrystal  Know-How  or
Collaboration Information and Inventions. Merck, upon notice to Cocrystal, shall have the first right to initiate and prosecute legal action at its expense and in

Cocrystal and, if necessary, Merck. Each Party shall have the right to be represented by counsel of its own choice at its own expense.

7.3.3

For any action to terminate any infringement of Cocrystal Patent Rights or Collaboration Patent Rights or any misappropriation or misuse of Cocrystal Know-
How or Collaboration Information and Inventions, in the event that a Party is unable to initiate or prosecute such action solely in its own name, the other Party
will join such action voluntarily and will execute and cause its Affiliates to execute all documents necessary for the Party to initiate litigation to prosecute and
maintain such action under this Section 7.3. In connection with any action or potential action, Merck and Cocrystal will cooperate fully and will provide each
other  with  any  information  or  assistance  that  either  may  reasonably  request,  including  cooperating  with  regard to  any  pre-litigation  review  of  the  Cocrystal
Patent Rights and Collaboration Patent Rights. Each Party shall keep the other informed of developments in any action or proceeding and provide the other
Party, upon request, with copies of documents filed  in connection therewith. For any proceeding, the controlling Party shall obtain the approval from the other
Party of any settlement offer or settlement agreement, which approval shall not be unreasonably withheld or delayed.

Any recovery  obtained  by  either  or  both  Merck  and  Cocrystal  in  connection  with  or  as  a  result  of  any  action  contemplated  by  this Section  7.3,  whether  by
settlement or otherwise, shall be shared in order as follows:

(a)

(b)

(c)

the Party which initiated and prosecuted the action shall recoup all of its costs and expenses incurred in connection with the action;

the other Party shall then, to the extent possible, recover its costs and expenses incurred in connection with the action; and

the amount of any recovery remaining shall then be allocated between the Parties on a pro-rata basis taking into consideration the relative economic
losses suffered by each Party.

7.3.5

Each Party shall inform the other Party of any certification regarding any Cocrystal Patent Rights or Collaboration Patent Rights it has received pursuant to
either 21 U.S.C. §§355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV), or its successor provisions or any similar provisions in a country in the Territory other than the United
States, and shall provide a copy of such certification within [*] of receipt. Merck has the first right to initiate and prosecute any legal action as a result of such
certification; provided, however, that Merck shall inform Cocrystal of such decision to initiate such action within [*] of receipt of the certification, after which
time  Cocrystal  shall  have  the  right  to  initiate  and  prosecute  such  action.  Regardless of  which  Party  has  the  right  to  initiate  and  prosecute  such  action,  both
Parties shall, as soon as practicable after receiving notice of such certification, convene and consult with each other regarding the appropriate course of conduct
for such action. The non-initiating Party shall have the right to be kept fully informed and participate in decisions regarding the appropriate course of conduct
for such action, and the right to join and participate in such action. Cocrystal’s and Merck’s  rights and obligations with respect to the prosecution of any legal
action as a result of such certification and any recovery obtained as a result of such legal action shall be as defined in Sections 7.3.3 and 7.3.4.

Termination for Cause.

8.3.1

Cause for Termination. This Agreement may be terminated at any time during the Term:

(a)

(b)

upon written notice by either Party if the other Party is in breach of its material obligations hereunder by causes and reasons within its control and has
not cured such breach within [*] after notice requesting cure of the breach; provided, however, in the event of a good faith dispute with respect to the
existence of a material breach, the [*] cure period shall be tolled until such time as the dispute is resolved pursuant to Section 9.7; or

by either  Party  (the  “Terminating Party”)  upon  the  filing  or  institution  of  bankruptcy,  reorganization,  liquidation or  receivership  proceedings,  or
upon an assignment of a substantial portion of the assets for the benefit of creditors by the other Party (the “Bankruptcy Party”); provided, however,
that in the case of any involuntary bankruptcy or receivership proceeding such right to terminate shall only become effective if the Bankruptcy Party
consents to such involuntary proceeding is not dismissed within [*] after the filing thereof.

8.3.2

Effect of Termination for Cause on License.

(a)

If either Party terminates this Agreement pursuant to Section 8.3.1, then [*] and each Party shall, within [*] after the effective date of such termination,
return or cause to be destroyed all Information of the other Party in tangible form and all Compound substances or compositions delivered or provided
by the other Party, as well as any other material provided by the other Party in any medium; provided, however, that each Party may retain one copy of
Information received from the other Party in its confidential files for record purposes, and Merck and its Affiliates may retain Information reasonably
necessary to practice under its continued licenses to use Cocrystal Know-How and Merck and its Affiliates shall have a fully paid-up [*] license to use
Cocrystal Know-How for research purposes only. For the avoidance of doubt, each Party may retain Collaboration Information and Inventions since
each Party has an undivided interest therein, and both Parties shall be entitled to exploit their interest under Collaboration Information and Inventions
and Collaboration Patent Rights, subject to Section 8.4, for any and all purposes without having to consult with, account to or seek consent from the
other Party.

(c)

Upon termination  of  this  Agreement  by  Merck  pursuant  to  Section  8.2,  or  by  Cocrystal  pursuant  to  Section  8.3.1(a),  Merck  and  its  Affiliates,
sublicensees  and  distributors  shall  be  entitled,  during  the  [*]  period  immediately  following  the  effective  date of termination, to finish any work-in-

If this Agreement is terminated by the Terminating Party pursuant to Section 8.3.1(b) due to the rejection of this Agreement  by or on behalf of the
Bankruptcy Party under Section 365 of the United States Bankruptcy Code (the “Code”), all licenses and rights to licenses granted under or pursuant
to this Agreement by the Bankruptcy Party to the Terminating  Party are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the
Code, licenses of rights to “intellectual property” as defined under Section 101(35A) of the Code. The Parties agree that the Terminating Party, as a
licensee of  such  rights  under  this  Agreement,  shall  retain  and  may  fully  exercise  all  of  its  rights  and  elections  under  the  Code,  and that  upon
commencement of a bankruptcy proceeding by or against the Bankruptcy Party under the Code, the Terminating Party  shall be entitled to a complete
duplicate  of  or  complete  access  to  (as  the  Terminating  Party  deems  appropriate),  any  such intellectual  property  and  all  embodiments  of  such
intellectual property. Such intellectual property and all embodiments thereof  shall be promptly delivered to the Terminating Party (i) upon any such
commencement of a bankruptcy proceeding upon written request therefore by the Terminating Party, unless the Bankruptcy Party elects to continue to
perform all of its obligations under this Agreement or (ii) if not delivered under (i) above, upon the rejection of this Agreement by or on behalf of the
Bankruptcy Party upon written request therefore by the Terminating Party. The foregoing provisions of this Section 8.3.2(c)  are without prejudice to
any rights the Terminating Party may have arising under the Code or other applicable law.

under  this Agreement prior to expiration or termination, including without limitation the obligation to pay royalties for  Product(s) or  Compound  sold  prior  to  such
expiration or termination. The provisions of Article 4 shall survive the expiration or termination of this Agreement and shall continue in effect for [*]. In addition, the
provisions of Article 1, Article 7 (with respect  to Collaboration Patent Rights), Article 8 and Article 9 shall survive any expiration or termination of this Agreement

ARTICLE 9 MISCELLANEOUS

  9.1

  9.2

Force Majeure.  Neither  Party  shall  be  held  liable  to  the  other  Party  nor  be  deemed  to  have  defaulted under  or  breached  this Agreement  for  failure  or  delay  in
performing any obligation under this Agreement to the extent such failure or delay is caused by or results from causes beyond the reasonable control of the affected
Party, potentially including, but not limited to, embargoes, war, acts of war (whether war be declared or not), acts of terrorism, insurrections, riots,  civil commotions,
strikes, lockouts or other labor disturbances, fire, floods, or other acts of God, or acts, omissions or delays in acting by any governmental authority or the other Party.
The affected Party shall notify the other Party of such force majeure circumstances as soon as reasonably practical, keep the other Party informed of the steps being
taken to remedy the circumstances and promptly undertake all reasonable and diligent efforts necessary to cure such force majeure circumstances.

Assignment/Change of Control. Except as provided in this Section 9.2, this Agreement may not be assigned or otherwise transferred, nor may any right or obligation
hereunder be assigned or transferred, by either Party without the consent of the other Party. Merck may, without Cocrystal’s consent, assign this Agreement and its
rights and obligations hereunder in whole or in part to a Merck Affiliate or in connection with a Change of Control (as defined below). Cocrystal may, without  Merck’s
consent, assign this Agreement and its rights and obligations hereunder in connection with a Change of Control; provided, however, that Cocrystal must notify Merck
at  least  [*]  prior  to  completion  of  any  such  Change  of  Control. Without  limiting  the  foregoing,  in  the  event  that  there  is  a  Company  Change  of  Control  that  is  a
Competing Pharma Change of Control, then Cocrystal shall provide written notice to Merck at least [*] prior to the completion of such Change of Control and [*]. Any
permitted  assignee  shall  assume  all  obligations  of  its  assignor  under  this Agreement. All  Patent  Rights,  know-how  or  other  intellectual  property  rights  licensed  to
Merck hereunder prior to any Change of Control (or otherwise coming under the Control of Cocrystal (or any of its Affiliates that were Affiliates prior to such Change
of  Control)  following  such  Change of  Control)  shall,  in  all  cases,  continue  to  be  licensed  to  Merck  hereunder  in  accordance  with  this Agreement. Any  attempted
assignment  not  in  accordance  with  this  Section  9.2  shall  be  void.  If  a  proposed  assignment  would  have  an  adverse  impact  upon the  tax  treatment  of  payments  due
under this Agreement to the other Party, the assigning Party shall undertake such steps  as are necessary to remedy such adverse impact. Notwithstanding anything in
this Agreement to the contrary, the Patent Rights,  know-how or other intellectual property owned or otherwise Controlled, as of the effective date of the Change of
Control of Cocrystal or its Affiliates and thereafter, by (i) any counterparty (a Third Party) to a Change of Control (the “ Acquirer”) of Cocrystal or its Affiliates (the
“Acquired Party”) or (ii) any of Acquirer’s Affiliates that are not Affiliates of the Acquired Party, in each case immediately prior to the closing of  such Change of
Control, shall not become subject to the license grants and other requirements of this Agreement. For purposes of this Section 9.2, a “Change of Control” of a Party
shall be deemed to occur if such Party is involved in a merger, reorganization or consolidation, or if there is a sale of all or substantially all of such Party’s assets or
business relating to this Agreement or if a person or group other than the current controlling person or group shall effectively acquire control of the management and
policies of such Party. For purposes of this Section 9.2, a “Competing Pharma Change of Control” shall mean [*].

  9.3

Use of Affiliates. Merck shall have the right to exercise its rights and perform its obligations under this Agreement either itself or through any of its Affiliates.

enforceability  of  the  remaining  provisions  contained  herein  shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s)
adversely  affects  the  substantive rights  of  the  Parties.  The  Parties  shall  in  such  an  instance  use  reasonable  efforts  to  replace  the  invalid,  illegal  or  unenforceable
provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.

Dispute Resolution.

9.7.1

9.7.2

The Parties shall negotiate in good faith and use reasonable efforts to settle any dispute, controversy or claim arising from or related to this Agreement or the
breach thereof (a “Dispute”). Any Party shall give the other Party written notice of any Dispute not resolved in the normal course of business and referring to
this Section 9.7.1. Within [*] from the date of delivery of such notice, the receiving Party shall submit to the other Party a written response. The notice and
response shall include (a) a statement of that Party’s position and a summary of arguments supporting that position, and (b) the name and title of the executive
who  will  represent  that  Party  and  of  any  other  person  who  will  accompany  the  executive. Within  [*]  from  the  date  of  delivery  of  the  initial  notice,  the
executives of both Parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to resolve
the Dispute. [*] All negotiations pursuant to this Section 9.7 are confidential and shall be treated as compromise and settlement negotiations for purposes of
applicable rules of evidence.

If the Parties do not fully settle following the procedure in Section 9.7.1, and a Party wishes to pursue the matter, each dispute, controversy or claim arising
from or related to this Agreement or the breach thereof that is not an Excluded Claim (as defined  below) shall be brought in the federal court located in New
York, New York, if federal jurisdiction is available, or, alternatively, in the state courts located in New York, New York. Each of the Parties hereby submits to
the exclusive jurisdiction of such courts for the purpose of any such litigation; provided, that a final judgment in any such litigation shall be conclusive and
may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each Party irrevocably and unconditionally agrees
not  to  assert  (a)  any  objection  which  it  may  ever  have  to  the  laying  of  venue  of  any  such  litigation in  such  courts,  (b)  any  claim  that  any  such
litigation brought in any such court has been brought in an inconvenient forum, and (c) any claim that such court does not have jurisdiction with
respect  to  such  litigation. EACH PARTY  IRREVOCABLY AND  UNCONDITIONALLY  WAIVES ANY  RIGHT  TO A  TRIAL  BY  JURY AND
AGREES  THAT  ANY  OF  THEM  MAY  FILE  A  COPY  OF  THIS  PARAGRAPH  WITH ANY  COURT AS  WRITTEN  EVIDENCE  OF  THE
KNOWING,  VOLUNTARY AND  BARGAINED-FOR AGREEMENT AMONG  THE  PARTIES  IRREVOCABLY  TO  WAIVE  ITS  RIGHT  TO
TRIAL BY JURY IN ANY LITIGATION.

9.7.3

As used in this Section 9.7, the term “Excluded Claim” shall mean a dispute, controversy or claim that concerns (a) a decision by the Committee or Merck
within the proper scope of the Committee’s authority pursuant to Section 2.6,  or an issue concerning the integrity of data submitted to a regulatory agency,
neither of which shall be justiciable in any forum; (b) the validity or infringement of a patent, trademark or copyright; or (c) any antitrust, anti-monopoly or
competition law or regulation, whether or not statutory. Any action concerning Excluded Claims identified in clauses (b) and (c) of this  Paragraph may be
brought in any court having jurisdiction.

  9.8

Limitation of Liability. Notwithstanding anything to the contrary contained herein, neither Party shall be liable to the other Party under any theory for any special,
incidental, indirect, consequential or other similar damages, or any punitive damages, whether arising directly or indirectly out of the transactions contemplated by this
Agreement.  To be clear, neither Party shall be entitled to recover for any lost profit or lost sale damages of any kind, whether those claimed damages  are  direct  or
indirect.

SCHEDULE 4.4 PRESS RELEASE

Cocrystal Pharma Announces Exclusive Worldwide License and
Collaboration Agreement with Merck

BOTHELL, WA, January  __,  2019  – Cocrystal Pharma, Inc. (NASDAQ: COCP), (“Cocrystal” or the “Company”), a clinical stage biotechnology company discovering and
developing novel antiviral therapeutics that target the replication machinery of influenza viruses, hepatitis C viruses and noroviruses, announced today that it has entered into an
exclusive license and collaboration agreement with Merck to discover and develop certain proprietary influenza A/B antiviral agents.

Under  the  terms  of  the  agreement,  Merck  will  fund  research  and  development  for  the  program,  including  clinical  development,  and  will  be  responsible  for  worldwide
commercialization of any products derived from the collaboration. Cocrystal will be paid an undisclosed upfront sum and is eligible to receive payments related to designated
development, regulatory and sales milestones with the potential to earn up to $156 million, as well as undisclosed royalties on product sales.

“We are thrilled to work with Merck, a preeminent research-intensive pharmaceutical company, to advance the development of certain influenza A/B antivirals. Our R&D team
has been intently focused on advancing our influenza program forward and we believe the combination of Merck resources and our innovative platform will enable us to rapidly
advance important new treatments for influenza, which is a significant worldwide unmet need,” commented Dr. Gary Wilcox, Vice Chairman and Chief Executive Officer of
Cocrystal.  “This  collaboration  is  a  significant  milestone  for  Cocrystal  that  we  believe  further  validates  our  approach  to  drug  discovery  with  our  unique  structure-based
technologies and Nobel Prize winning expertise to create first- and best-in-class antiviral drugs.”

“Collaborations like this are an integral part of our infectious disease R&D strategy,” said Dr. Daria Hazuda, Chief Scientific Officer Merck Exploratory Science Center and
Vice President Infectious Diseases and Vaccines Discovery, Merck Research Laboratories. “New meaningful options for the treatment of influenza are badly needed. We look
forward to working with Cocrystal’s experienced team.”

Forward-Looking Statements

This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including our expectations regarding the
timing for achievement of certain research and clinical development milestones related to the licensing agreement with Merck as well as royalties on any product sales. The
words “believe,” “may,” “estimate,” “continue,” “anticipate,” “intend,” “should,” “plan,” “could,” “target,” “potential,” “is likely,” “will,” “expect” and similar expressions, as
they relate to us, are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about
future events. Some or all of the events anticipated by these forward-looking statements may not occur. Important factors that could cause actual results to differ from those in
the forward-looking statements include the availability of products manufactured by third parties, the results of planned research and, if successful, clinical trials, and receipt of
regulatory  approvals.  Further  information  on  our  risk  factors  is  contained  in  our  filings  with  the  SEC,  including  our  Quarterly  Report  on  Form  10-Q  for  the  quarter  ended
September  30,  2018,  the  Prospectus  Supplement  dated  July  19,  2018,  and  our Annual  Report  on  Form  10-K  for  the  year  ended  December  31,  2017. Any  forward-looking
statement made by us herein speaks only as of the date on which it is made. Factors or events that could cause our actual results to differ may emerge from time to time, and it is
not  possible  for  us  to  predict  all  of  them.  We  undertake  no  obligation  to  publicly  update  any  forward-looking  statement,  whether  as  a  result  of  new  information,  future
developments or otherwise, except as may be required by law.
