ITEM 1. BUSINESS

Overview

PART I

We  are  a  clinical-stage  biopharmaceutical  company  focused  on  the  discovery,  development  and  commercialization  of  first-in-class  pharmaceutical
therapies  to  treat  ocular  surface  diseases.  Our  lead  product  candidate  OC-01  (varenicline),  a  highly  selective  nicotinic  acetylcholine  receptor  (nAChR)
agonist, is being developed as a nasal spray to treat the signs and symptoms of dry eye disease (DED). OC-01’s novel mechanism of action is designed to re-
establish tear film homeostasis by activating the trigeminal parasympathetic pathway and stimulating the glands and cells responsible for natural tear film
production. In our Phase 2b clinical trial (ONSET-1) in 182 subjects, OC-01 demonstrated statistically significant improvements (as compared to placebo) in
both signs and symptoms of DED in a single registrational clinical trial. Based on OC-01’s clinical trial results and its rapid onset of action, we believe OC-
01, if approved, has the potential to become the new standard of care and redefine how DED is treated for millions of patients. We initiated a Phase 3 clinical
trial (ONSET-2) in July 2019 and expect to report top-line results by the end of the second quarter 2020. Based on the results from this second registrational
trial,  we  plan  to  submit  a  New  Drug  Application  (NDA)  to  the  U.S.  Food  and  Drug  Administration  (FDA)  in  the  second  half  of  2020.  We  believe  that
targeting the parasympathetic nervous system through the use of locally administered cholinergic agonists has the potential to treat a wide range of diseases
and disorders. We have identified several indications, including several outside of ophthalmology, where we believe this approach could provide a meaningful
benefit to patients.

DED is a multifactorial chronic disease of the ocular surface characterized by the loss of tear film homeostasis, resulting in pain, visual impairment, tear
film hyperosmolarity and instability, inflammation, and corneal wounding. More than 340 million adults globally and approximately 34 million adults in the
United States are estimated to suffer from DED. In the United States, DED is most commonly treated with a variety of over-the-counter eye drops, often
referred  to  as  “artificial  tears,”  and  three  FDA-approved  prescription  eye  drop  therapies:  Restasis,  Xiidra  and  Cequa.  Artificial  tears  are  intended  to
supplement insufficient tear production or improve tear film instability, but are primarily saline-based and provide only temporary relief. Restasis and Cequa,
both  calcineurin  inhibitor  immunosuppressants,  and  Xiidra,  a  lymphocyte  function-associated  antigen-1  (LFA-1)  antagonist,  address  chronic  inflammation
associated  with  DED.  Despite  the  commercial  uptake  of  these  therapies—as  examples,  Restasis,  marketed  by  Allergan,  and  Xiidra,  recently  acquired  by
Novartis,  had  U.S.  sales  in  2018  of  $1.2  billion  and  $383  million,  respectively—respondents  in  a  survey  we  commissioned  in  June  2017  of  150  board-
certified  or  board-eligible  eye  care  practitioners  (ECPs)  were  generally  “neutral”  or  “completely  disagreed”  with  the  statement  that  they  could,  in  their
opinion, successfully treat all DED patients with the currently available treatment options whereas only 10% “completely agreed” with such statement. We
estimate that of the approximately seven million patients who have started a prescription treatment to date, fewer than two million remain on prescription at
any given time due to the significant limitations of these therapies, which include:

•

•

•

Mechanisms of action only address inflammation. Currently approved therapies only target inflammation for moderate to severe DED; no
approved pharmaceutical products replicate natural tear film, which is highly complex in composition. As these prescription therapies fail
to address the fundamental characteristic of DED, the loss of tear film homeostasis, we estimate that 75% of patients still require over-the-
counter therapies to supplement their treatment.

Slow onset of action. Based on data reported from clinical trials, currently available treatments can take between three to six months to
demonstrate a significant effect in clinical signs. We believe this delayed onset of action hinders compliance and in turn limits the benefit
that patients derive from such treatments.

Tolerability and compliance issues. Currently approved pharmaceutical therapies for DED are typically administered in an eye-drop
formulation and are commonly associated with ocular burning, reduced visual acuity and bad taste after application. The effective use of
eye drops can be challenging for some patients, and such challenges can result in reduced compliance.

To address these limitations and the high unmet need expressed by patients, ECPs and payors, we are developing a product candidate that we believe has
the potential to become the new standard of care for DED. However, there is no guarantee that such product candidate will be approved by the FDA or, if
approved, will provide revenues comparable to Restasis or Xiidra.

Our novel approach leverages the parasympathetic nervous system to promote natural tear film production and re-establish tear film homeostasis. Human
tear film is a complex mixture of more than 1,500 different proteins, including antibodies, and numerous classes of lipids and mucins that are responsible for
forming  the  primary  refracting  surface  of  the  cornea,  as  well  as  protecting  and  moisturizing  the  cornea.  The  Lacrimal  Functional  Unit  (LFU),  which  is
controlled by the parasympathetic nervous

3

system, is comprised of glands and cells responsible for producing the three layers that comprise healthy tear film. To stimulate the LFU, we are targeting a
class of receptors called nicotinic acetylcholine receptors (nAChR) that are located on the trigeminal nerve and readily accessible within the anterior nasal
cavity. Administered as a preservative-free, aqueous nasal spray, OC-01’s novel mechanism of action activates the trigeminal parasympathetic pathway to
promote  natural  tear  film  production.  We  believe  that  increasing  tear  film  volume  and  re-establishing  tear  film  homeostasis  will  address  the  fundamental
characteristic of DED, regardless of etiology, and has the potential to treat a broad population of patients throughout the dry eye continuum.

To date, we have treated over 500 subjects across five trials with OC-01 and OC-02 (simpinicline, which was formerly called simpanicline), our second
nAChR agonist product candidate. We have consistently designed our clinical trials to be placebo (vehicle)-controlled, statistically rigorous and evaluated
using pre-specified sign and symptom endpoints. In October 2018, we reported results from ONSET-1, a dose-ranging, randomized, double-masked, placebo-
controlled, registrational Phase 2b clinical trial that evaluated the safety and efficacy of OC-01 in 182 subjects with DED in the United States. The study
compared  three  different  doses  of  OC-01  to  placebo.  The  pre-specified  primary  (sign)  endpoint  was  the  assessment  of  tear  production  as  measured  by
Schirmer’s Score at Week 4 and the two pre-specified secondary (symptom) endpoints were patient-reported symptoms of DED as measured by Eye Dryness
Score (EDS) at Weeks 3 and 4. These endpoints are consistent with those that have been previously utilized in clinical trials of FDA-approved products for
DED. Results showed statistically significant improvements of the primary endpoint (Schirmer’s Score) at all doses compared to placebo. In addition, results
showed statistically significant improvements of the secondary endpoint (EDS) at Week 3 in the 0.6 mg/ml (p=0.006) and 1.2 mg/ml (*p<0.001) dose groups
and at Week 4 in the 0.6 mg/ml (p=0.021) dose group. Moreover, OC-01 is designed to promote rapid production of tear film, and improvements in signs and
symptoms were observed as quickly as five minutes after administration. OC-01 was well tolerated at all doses assessed in the study with no serious drug-
related adverse events reported.

We met with the FDA in February 2019 for an end of Phase 2 meeting following the completion of ONSET-1, and the FDA indicated ONSET-1 could
serve as one of the two pivotal safety and efficacy studies required to support an NDA filing for OC-01. Based on this feedback we initiated ONSET-2, a 750-
subject, multicenter, randomized, double-masked, placebo-controlled Phase 3 trial, in July 2019. Assuming the effect size seen in ONSET-1, and based on this
sample size, the power for each dose group for both sign and symptom endpoints would be 99% or greater. We expect to report top-line results from this
second registrational trial by the end of the second quarter 2020 and, if successful, submit an NDA to the FDA in the second half of 2020.

We  also  completed  a  comparative  pharmacokinetic  “bridge”  trial  (ZEN)  to  evaluate  the  relative  bioavailability  of  varenicline  administered  as  a  nasal
spray (OC-01) compared to varenicline administered orally (Chantix). The FDA has indicated that reliance upon the varenicline tartrate data in our 505(b)(2)
NDA submission would be considered scientifically justified if exposure levels following nasal spray administration of our final clinical formulation are less
than or equal to that of Chantix at its approved dose and route of administration. We reported positive top-line results in November 2019 illustrating that the
exposure levels following nasal spray administration are significantly lower than those seen with oral varenicline.

Leveraging our nAChR domain expertise, we continue to explore the development of OC-01 for a number of potential indications and uses associated
with and beyond DED, including neurotrophic keratitis, dry eye associated with contact lens intolerance and ocular surface treatment for refractive surgeries.
We have also studied OC-02 in two Phase 2b clinical trials in subjects with DED. However, we do not currently intend to pursue FDA approval for OC-02 in
DED. We believe that targeting the parasympathetic nervous system through the use of locally administered cholinergic agonists has the potential to treat a
wide range of diseases and disorders in the eye and systemically.

To execute on our vision to develop and commercialize a new standard of care for DED, we have assembled a team with extensive experience developing
and  commercializing  leading  ophthalmic  products  and  therapies.  Members  of  our  management  team  have  held  senior  positions  at  Allergan,  Eyetech,
Genentech, Johnson & Johnson, Novartis, Oculeve, Ophthotech, Pfizer, Pharmasset, and Shire. We intend to leverage this expertise and experience to rapidly
pursue the development of OC-01, OC-02 and any other future product candidates that we may identify and develop. We also have leading financial investors
which include New Enterprise Associates, Versant Ventures, Invus Opportunities, Flying L Ventures (investing through its Oyster Point Pharma I fund), KKR
(investing through its Falcon Vision fund) and Vida Ventures.

Our Strategy

Our  goal  is  to  transform  the  treatment  of  DED  and  other  ocular  surface  diseases  by  developing  a  broad  portfolio  of  innovative  therapies  that  target

significant unmet medical needs. We intend to achieve this goal by pursuing the following key strategic objectives:

4

•

•

•

•

•

•

Completing development and obtaining approval of OC-01 for the treatment of DED. OC-01 demonstrated statistically significant
improvements (as compared to placebo) in both signs and symptoms of DED in a single registrational clinical trial. We are not aware of
another  therapy  that  has  shown  statistically  significant  improvements  in  both  signs  and  symptoms  of  DED  in  a  single  registrational
clinical trial. However, to date our trials have been designed as randomized, masked, placebo-controlled clinical trials and, as such, we
have not tested OC-01 head-to-head with any other products or therapies, nor are we aware of any head-to-head results indicating that
such other products or therapies could not have shown similar results. Based on the strength of the data observed in ONSET-1, our Phase
2b registrational clinical trial, we initiated a Phase 3 multicenter, randomized, double-masked, placebo-controlled clinical trial (ONSET-
2).  We  expect  to  report  top-line  results  from  this  second  registrational  trial  by  the  end  of  the  second  quarter  2020  and,  if  successful,
submit a 505(b)(2) NDA to the FDA in the second half of 2020.
Establishing  our  own  specialty  sales  organization  to  commercialize  OC-01  in  the  United  States.  If  OC-01  is  approved  for  the
treatment of the signs and symptoms of DED, we intend to commercialize our lead product candidate by deploying a specialty sales force
at  launch  of  approximately  150  to  200  field  representatives  targeting  the  top-prescribing  ophthalmologists  and  optometrists.  Given  the
importance of increasing awareness and educating patients with DED, we also anticipate deploying focused direct-to-consumer marketing
campaigns for OC-01. We anticipate that this sales organization could also support the commercialization of additional product candidates
treating ocular diseases.

Maximizing the value of OC-01 and our other product candidates outside the United States. With more than 300 million additional
DED  patients  outside  of  the  United  States,  we  believe  there  is  a  significant  commercial  opportunity  for  our  product  candidates
internationally. To address these markets, we may seek one or more partners with regional capabilities and infrastructure to support and
potentially accelerate the clinical development and commercialization of our product candidates, if approved, in such geographies.

Developing OC-01 for additional indications associated with and beyond DED. Based on the fundamental role of natural tear film in
ocular surface health, we plan to pursue development of OC-01 in other indications where this equilibrium is disturbed. First, we plan to
pursue  development  for  patients  with  neurotrophic  keratitis,  a  degenerative  disease  resulting  from  a  loss  of  corneal  sensation,  which
causes  progressive  damage  to  the  top  layer  of  the  cornea.  As  natural  tear  film  contains  a  myriad  of  beneficial  components,  including
endogenous growth factors, proteins and antibodies, we believe that our product candidate could be beneficial in improving the health of
the  cornea  in  these  patients.  A  second  population  of  potential  clinical  benefit  is  in  subjects  with  DED  associated  with  contact  lens
intolerance.  In  addition,  based  on  the  unique  characteristics  of  this  product  candidate,  we  see  the  potential  for  use  in  patients  that  are
preparing for refractive surgery where there is often an underlying dry eye condition that could impact refraction and ultimately patient
satisfaction and quality of life post-surgery.

Leveraging  the  capabilities  of  our  experienced  discovery  and  development  team  and  our  nAChR  domain  expertise  to  continue
expanding our pipeline of product candidates. We have studied a second nAChR agonist product candidate OC-02 (simpinicline) in
two Phase 2b clinical trials for DED. We have identified several indications, other than DED, where we believe this product candidate has
the potential to provide a meaningful benefit to patients. In certain indications, we believe OC-02 could advance directly into a Phase 2
proof of concept study, supported by preclinical and clinical data that we and others have generated. However, we cannot guarantee that
the FDA will permit us to advance OC-02 into a Phase 2 proof of concept study nor can we guarantee that the FDA will grant marketing
approval to OC-02 for the treatment of any indication. Beyond OC-02, we plan to continue our efforts to identify and develop additional
product candidates.

Selectively evaluating external opportunities to expand the scope of our pipeline or product offerings. We may pursue acquisition or
in-licensing of product candidates, particularly in our core disease area of ocular surface diseases.

Dry Eye Disease Overview

Dry eye disease (DED) is a multifactorial, age-related chronic progressive disease of the ocular surface resulting in pain, visual impairment, tear film
hyperosmolarity  and  instability,  and  inflammation.  Patients  with  DED  are  also  more  susceptible  to  eye  infections  and  damage  to  the  surface  of  the  eye
(cornea). DED is characterized by a reduction in tear volume, rapid breakup of the tear film, or an increase in the evaporative properties of the tear film layer.
DED affects daily life, including reading and

5

driving at night and has been associated with depression and migraines. DED can also limit patients’ ability to tolerate contact lenses and impacts patient
satisfaction with post-op cataract and refractive patients.

As  illustrated  below,  the  Lacrimal  Functional  Unit  (LFU),  which  is  controlled  by  the  parasympathetic  nervous  system,  is  comprised  of  Meibomian
glands, lacrimal glands, and goblet cells that are responsible for producing the three layers that comprise healthy tear film. The National Eye Institute defines
healthy  tear  film  as  “a  complex  mixture  of  fatty  oils,  water,  mucus,  and  more  than  1,500  different  proteins  that  keep  the  surface  of  the  eye  smooth  and
protected from the environment, irritants, and infectious pathogens.” The outermost layer of tear film is a lipid layer produced by the Meibomian glands that
keeps tear film from evaporating too quickly. The lacrimal glands produce the aqueous layer, which comprises the bulk of tear volume and flow. This middle
layer  is  not  just  water  –  it  contains  thousands  of  proteins,  enzymes,  antibodies  and  growth  factors  that  are  cytoprotective,  anti-inflammatory,  and  anti-
microbial. The aqueous layer nourishes the cornea and the conjunctiva, the mucous membrane that covers the entire front of the eye and the inside of the
eyelids. Finally, the innermost mucin layer is produced by goblet cells and binds water from the aqueous layer to ensure that the eye remains wet. The LFU
receives stimulus from the trigeminal nerve, which has sensory nerve endings in the nasal cavity.

LFU dysfunction leads to the loss of tear film homeostasis and can ultimately lead to the cycle of chronic DED. Disruption and instability of the tear film
results in irritation, inflammation, and ultimately cellular damage. Chronic symptoms of DED include a scratchy sensation (foreign body sensation), stinging
or  burning,  episodes  of  excess  tearing  that  follow  periods  of  dryness,  discharge,  pain,  and  redness  in  the  eye.  In  addition,  patients  with  dry  eye  often
experience  blurred  vision  as  the  cornea  and  the  tear  film  are  responsible  for  65%-75%  of  the  eye’s  focusing  power.  Approved  prescription  treatments  for
DED, as well as therapies in clinical development, target inflammation further down the DED continuum. We believe these therapies only treat patients with
moderate to severe DED and do not address the loss of tear film homeostasis, the fundamental characteristic of DED. Our lead product candidate OC-01 is
designed to stimulate the LFU to produce natural tear film, re-establish tear film homeostasis and improve the signs and symptoms of patients with DED.

Market opportunity in DED

6

DED is highly prevalent and growing, currently affecting more than 340 million people globally. In the United States, DED affects an estimated 14.5% of
the adult population, or 34 million adults, resulting in greater than $55 billion in annual indirect costs, such as reductions in productivity. Prevalence of DED
continues to grow due to an aging population, increase in autoimmune diseases, contact lens wear and digital screen time. Although DED is one of the most
common reasons people visit an ECP in the United States, it is estimated that only 16 million adults have been diagnosed with DED by an ECP, which we
believe is due in part to lack of education and insufficient awareness on the part of the patient.

Despite the number of patients diagnosed with DED, we estimate that only seven million patients to date have started a prescription treatment regimen which
we  believe  is  based  at  least  in  part  on  a  lack  of  treatment  options  that  are  suitable  for  chronic  use.  In  a  survey  we  commissioned  in  June  2017  (the  ECP
Survey)  of  eye  care  practitioners  (ECPs),  respondents  were  generally  neutral  or  dissatisfied  with  their  treatment  options  for  patients  with  DED.  The  ECP
Survey was conducted by means of a distributed questionnaire to 150 respondent ECPs who specialize primarily in ophthalmology or optometry, are board-
certified  or  board-eligible,  manage  at  least  40  unique  patients  per  month  with  DED  and  are  familiar  with,  or  prescribe,  currently  available  prescription
therapies. In the ECP Survey, we asked ECPs to select whether they completely disagreed, were neutral or completely agreed with the statement that they
“can successfully treat all Dry Eye patients with currently available options.” Approximately 40% of ECPs responded that they completely disagreed with the
statement,  approximately  50%  responded  that  they  were  neutral  and  only  10%  responded  that  they  completely  agreed.  Similarly,  the  top  clinical  reasons
patients  discontinued  therapy  were  insufficient  symptom  improvement,  side  effects,  and  delayed  onset  of  action.  Medication  cost  was  also  a  factor  in
discontinuing therapy. However, in our survey of patients who had discontinued Restasis due to costs, 72% stated they would have been willing to pay the
same price if the medication had worked better. As a result of these factors, we believe that only two million patients are on a prescription therapy at any
given time. Despite the small percentage of DED patients on prescription therapy, Restasis (marketed by Allergan) and Xiidra (recently acquired by Novartis
for a total consideration of up to $5.3 billion) had U.S. sales in 2018 of $1.2 billion and $383 million, respectively. However, we cannot guarantee that OC-01
or any of our other future product candidates will be approved by the FDA and, even if one of our product candidates is approved, there is no guarantee that
our revenues will be comparable to those of Restasis or Xiidra.

Current treatment options and their limitations

DED is primarily treated with a variety of over-the-counter eye drops, often referred to as “artificial tears,” and three FDA-approved prescription eye
drop therapies: Restasis, Xiidra and Cequa. Artificial tears are intended to supplement insufficient tear production or improve tear film instability, but are
primarily  saline-based  and  provide  only  temporary  relief.  Restasis  and  Cequa,  both  calcineurin  inhibitor  immunosuppressants,  and  Xiidra,  a  lymphocyte
function-associated  antigen-1  (LFA-1)  antagonist,  which  has  been  approved  for  the  treatment  of  the  signs  and  symptoms  of  DED,  address  chronic
inflammation  associated  with  DED.  Other  treatment  options  include  ointments,  gels,  warm  compresses,  omega-3  fatty  acid  supplements  and  a  number  of
medical devices. Unfortunately, all currently approved treatment options for DED have significant limitations, which include:

•

•

•

Mechanisms of action only address inflammation. Currently approved therapies only target inflammation for moderate to severe DED; no
approved pharmaceutical products replicate natural tear film, which is highly complex in composition. As these prescription therapies fail
to address the fundamental characteristic of DED, the loss of tear film homeostasis, we estimate that 75% of patients still require over-the-
counter therapies to supplement their treatment.

Slow onset of action. Based on data reported from clinical trials, currently available treatments can take between three to six months to
demonstrate a significant effect in clinical signs. We believe this delayed onset of action hinders compliance and in turn limits the benefit
that patients derive from such treatments.

Tolerability  and  compliance  issues.  Currently  approved  pharmaceutical  therapies  for  DED  are  typically  administered  in  an  eye-drop
formulation and are commonly associated with ocular burning, reduced visual acuity and bad taste after application. The effective use of
eye drops can be challenging for some patients and result in reduced compliance.

To address these limitations and the high unmet need expressed by patients, ECPs and payors, we have been developing OC-01, which we believe, if
approved, has the potential to become the new standard of care for DED. However, there is no guarantee that it will provide revenues comparable to existing
treatments. OC-01’s highly differentiated mechanism of action is designed to re-establish tear film homeostasis, addressing the fundamental disease process,
regardless  of  stage  of  disease  or  underlying  cause.  We  are  not  aware  of  any  other  drug  companies  focused  on  activating  the  trigeminal  parasympathetic
pathway  (TPP)  and  stimulating  the  LFU  to  increase  tear  production.  OC-01  has  demonstrated  rapid  onset  of  action  to  significantly  improve  signs  and
symptoms in the same patient population within a single registrational clinical trial. Furthermore, the novel delivery of

7

OC-01 in a nasal spray spares the ocular surface and contributes to a favorable tolerability profile. To date, there have been no reports of burning or stinging
to  the  ocular  surface  or  negative  effects  on  taste  or  smell  in  clinical  trials  of  OC-01.  We  believe  OC-01,  if  approved,  has  the  potential  to  offer  improved
clinical outcomes and patient compliance based on its registrational trial results, favorable tolerability profile and rapid onset of action, therefore making it
particularly suitable for use broadly across mild, moderate and severe patient populations.

Our approach: activating the trigeminal parasympathetic pathway to promote natural tear film production

To address these limitations and the high unmet need expressed by patients, ECPs and payors, we are developing a product candidate that we believe has
the  potential  to  serve  as  the  new  standard  of  care  for  DED.  Our  novel  approach  is  designed  to  leverage  the  parasympathetic  nervous  system  to  stimulate
natural  tear  film  production  and  re-establish  tear  film  homeostasis.  A  healthy  tear  film  protects  and  lubricates  the  eyes,  washes  away  foreign  particles,
contains antimicrobials to reduce the risk of infection, and creates a smooth surface that contributes refractive power for clear vision.

The Trigeminal Parasympathetic Pathway

The  parasympathetic  nervous  system  (PNS)  is  a  division  of  the  autonomic  nervous  system  and  is  responsible  for  actions  such  as  stimulating  gland
function,  constriction  of  the  pupil,  slowing  down  heart  rate  and  contractility,  contracting  bronchial  musculature  and  stimulating  bronchial  secretions,  and
increasing  gut  motility  for  digestion.  The  parasympathetic  nervous  system  controls  tear  film  homeostasis  and  the  activity  of  the  LFU  partially  via  the
trigeminal nerve. The PNS uses acetylcholine (ACh) as its neurotransmitter.

Anesthetizing the nasal mucosa has been shown to result in a 34% reduction in tear film production. This has also been observed in patients with reduced
nasal  air  flow  resulting  from  severe  nasal  allergy  and  patients  with  tracheostomy,  suggesting  that  stimulation  of  the  trigeminal  nerve  is  important  for  tear
production. Since then, additional studies have demonstrated a persistent decrease in aqueous tear production in patients with trigeminal nerve damage (such
as trauma, trigeminal nerve ablation and herpetic infection) or pathology.

We refer to the communication between the trigeminal nerve and the LFU as the TPP. The efferent paths (away from the nose) of the TPP proceed from
the  superior  salivary  nucleus  along  the  facial  nerve  to  the  geniculate  ganglion  and  from  there  through  the  greater  superficial  petrosal  nerve  via  the
sphenopalatine ganglion to the LFU. Activating the TPP results in the stimulation of the Meibomian glands, lacrimal glands (main and accessory), and goblet
cells comprising the LFU and promotes natural tear film production.

Targeting nicotinic acetylcholine receptors (nAChR) on the trigeminal nerve

Our approach to DED relies on a pharmaceutical stimulation of a class of receptors called nicotinic acetylcholine receptors (nAChR) that are located on
the trigeminal nerve and readily accessible within the anterior nasal cavity. nAChRs are ligand-gated ion channels that when bound by an agonist have the
potential  for  ganglionic  neurotransmission.  The  nAChRs  subtypes  found  on  human  neurons  are  comprised  of  various  homomeric  (all  one  subunit)  or
heteromeric  (at  least  one  α  and  one  ß  subunit)  combinations  of  12  different  nicotinic  receptor  subunits:  α2-α10  and  ß2-ß4.  Stimulation  of  these  receptors
results in a rapid increase in cellular permeability to Na + and Ca 2+ resulting  in  depolarization  of  the  cell  membrane  and  initiation  of  an  action  potential.
However,  not  all  subtypes  of  nAChRs  have  the  ability  to  activate  the  TPP  (for  example,  treatment  with  a  homomeric  α7  agonist  has  no  effect  on  this
pathway). Additionally, the functional response of an nAChR to agonists is comprised of two dose-dependent, opposing effects: receptor activation after short
exposure to high agonist concentrations (µM range), and desensitization upon prolonged exposure to low agonist concentrations (nM range).

Our  product  candidates  OC-01  and  OC-02  contain  APIs  that  are  highly  selective  to  the  nAChRs  that  activate  the  TPP.  We  believe  this  is  the  first
application  of  nAChR  agonists  to  be  delivered  nasally  to  stimulate  the  nerves  of  the  PNS.  Additionally,  we  have  found  that  OC-01  and  OC-02’s  unique
receptor binding characteristics and the localized nasal delivery allows for short-term agonist exposure with a high local concentration, and, once absorbed
across the nasal mucosa, results in low systemic exposure and therefore avoids desensitization.

Our Product Candidates

8

OC-01 (varenicline) nasal spray for Dry Eye Disease

Our lead product candidate OC-01 is being developed as a nasal spray to treat the signs and symptoms of DED. The API of OC-01, varenicline, is a
highly selective nicotinic acetylcholine receptor (nAChR) agonist with full agonist activity at the α7 receptor and partial agonist activity at the α3ß4, α3α5ß4,
α4ß2, and α4α6ß2 receptors. Varenicline tartrate, marketed as Chantix, was developed and commercialized by Pfizer as an aid to smoking cessation treatment.
The compound was studied in multiple dose-ranging, placebo-controlled Phase 2 studies as well as two confirmatory Phase 3 studies to study the safety and
efficacy in otherwise healthy smokers in the United States. In 2006, varenicline was approved by both the FDA and the European Medicines Agency and
subsequently has been approved in more than 80 other countries throughout the world. To date, varenicline oral tablets have been prescribed to more than 20
million patients worldwide, including more than 11 million adults in the United States.

OC-01 is a preservative-free, aqueous nasal spray designed to be delivered twice daily to each nostril in a 50 µl spray for the treatment of dry eye disease.
The highest intranasal concentration of varenicline being studied in ONSET-1 and ONSET-2 is 1.2 mg/ml, approximately ten-fold lower than the maintenance
dose  of  Chantix  (2  mg/day)  on  a  nominal  daily  dosing  basis.  The  lower  dose  of  0.6  mg/ml  varenicline  being  studied  in  these  two  registrational  trials  is
approximately 20-fold lower than the maintenance dose of oral Chantix on a nominal daily dosing basis.

OC-01’s novel mechanism of action

OC-01’s  novel  mechanism  of  action  is  designed  to  re-establish  tear  film  homeostasis  by  stimulating  the  trigeminal  nerve,  activating  the  TPP  and
stimulating the glands and cells responsible for natural tear film production. We believe that the development of OC-01 as a nasal spray represents the first
pharmacological treatment approach for DED targeting the nerves that control the LFU. OC-01, when sprayed into the anterior portion of the nasal cavity,
stimulates nAChRs located on the chemosensory endings of the trigeminal nerve resulting in cholinergic neurotransmission.

Once OC-01 is bound to an nAChR, it stabilizes the open state of the ion channel allowing influx of cations such as Ca2+ and Na + ions, thus creating an
action potential. This action potential ultimately activates the glands and cells of the LFU to produce natural tear film. Once the nasal spray is delivered, it
takes approximately 10-15 seconds before tear film is produced. The receptors can be in the activated state for many minutes to hours after stimulation (a
process termed smoldering activation).

We believe that increasing tear film volume and re-establishing tear film homeostasis will address the fundamental characteristic in the development and

treatment of DED, regardless of etiology, and has the potential to treat a broad population of patients throughout the dry eye continuum.

Our development program for OC-01

In  October  2018,  we  reported  results  from  ONSET-1,  a  multicenter,  dose-ranging,  randomized,  double-masked,  placebo  (vehicle)-controlled,
registrational Phase 2b clinical trial that evaluated the safety and efficacy of OC-01 in 182 subjects with DED in the United States. Following ONSET-1, we
initiated a Phase 3 registrational clinical trial (ONSET-2) in July 2019 and expect to report top-line results by the end of the second quarter 2020.

We  also  completed  a  comparative  pharmacokinetic  “bridge”  trial  (ZEN)  to  evaluate  the  relative  bioavailability  of  varenicline  administered  as  a  nasal
spray (OC-01) compared to varenicline administered orally (Chantix) and reported top line results in November 2019. The exposure levels following nasal
spray administration of varenicline are significantly lower than those seen with oral varenicline. If the FDA determines that the results of this trial establish an
adequate bridge between OC-01 and Chantix, it will allow us to reference certain FDA conclusions regarding the safety of varenicline from the Agency’s
review of the Chantix

9

NDA. If both ONSET-2 and ZEN are successful, we intend to submit the results of ONSET-2 and ZEN together with the results from ONSET-1 as part of a
505(b)(2) NDA to the FDA in the second half of 2020.

In January 2020, we reported results from MYSTIC, a randomized, single-masked, vehicle-controlled Phase 2 clinical trial that evaluated the safety and
efficacy  of  OC-01  in  123  subjects  with  DED.  The  goal  of  this  study  was  to  assess  the  safety  and  efficacy  of  twice  daily  dosing  of  OC-01  nasal  spray
administered for 84 days. Although the study will add to the totality of the data in support of the efficacy of OC-01 nasal spray in subjects with DED, the
MYSTIC data will only be used to support the safety of OC-01 in terms of NDA submission.

Statistical Significance

In the description of our clinical trials below, n represents the number of patients in a particular group and p or p-values represent the probability that
random chance caused the result (e.g., a p-value=0.001 means that there is a 0.1% probability that the difference between the placebo group and the treatment
group  is  purely  due  to  random  chance).  A  p-value  ≤  0.05  is  a  commonly  used  criterion  for  statistical  significance,  and  may  be  supportive  of  a  finding  of
efficacy by regulatory authorities. The confidence interval (CI) means a range of values for a variable of the measure of treatment effect, constructed so that
this range has a specified probability of including the true value of the variable.

ONSET-1: Phase 2b clinical trial results

In ONSET-1, OC-01 demonstrated statistically significant improvements in both signs and symptoms of DED. The study compared three different doses
of OC-01 to placebo. The pre-specified primary (sign) endpoint was the assessment of tear production as measured by Schirmer’s Score (compared to the
baseline Schirmer’s Score) at Week 4 and the two pre-specified secondary (symptom) endpoints were patient-reported symptoms of DED as measured by
EDS at Weeks 3 and 4. We also evaluated corneal fluorescein staining, a marker of corneal epithelial cell health, at Week 4, as an exploratory endpoint in
ONSET-1. Due to the relatively small sample size of the study and the use of the controlled adverse environment chamber (CAE) that can exacerbate staining,
ONSET-1 was not designed or powered to assess statistical significance for this endpoint. Baseline disease characteristics were generally similar across all
treatment groups, with the exception of the 1.2 mg/ml OC-01 dose group where lower average disease severity was observed as indicated by a higher mean
Schirmer’s test (5.5 mm) relative to the other dose groups (range: 4.5 to 5.2 mm) and a lower mean EDS (53.5 mm) relative to the other dose groups (range:
63.7 to 65.6 mm).

Although  we  cannot  guarantee  that  the  FDA  will  grant  marketing  approval  for  OC-01  based  on  the  use  of  these  endpoints,  ONSET-1’s  pre-specified
endpoints are consistent with those that have been previously utilized in clinical trials of FDA-approved products for DED. The Schirmer’s Score, which was
the same primary sign endpoint used in the FDA’s approval of Restasis, is determined by placing a test strip in the lower eyelid pouch and measuring the
length of the test paper strip that is moistened after five minutes. Sometimes a topical anesthetic is placed into the eye before the filter paper to prevent tearing
due to the irritation from the paper. The study eye was pre-defined as the eye that met eligibility criteria in the study and in the event that both eyes met
criteria, was the eye with more tearing at baseline upon stimulation or in the event that both eyes were again equal, the eye with the worse baseline Schirmer’s
Score. The fellow eye is the eye that was not defined as the study eye and may or may not have met all study eligibility criteria. The EDS, which was the
primary  symptom  endpoint  used  in  the  FDA’s  approval  of  Xiidra,  is  based  on  the  patient’s  rating  of  eye  dryness  on  a  visual  analog  scale  (where  0=no
discomfort and 100=maximal discomfort) with respect to both eyes. The study was designed and pre-specified to statistically analyze the 0.6 mg/ml and 1.2
mg/ml OC-01 dose groups. The study was not designed to formally analyze the 0.12 mg/ml dose group to avoid spending statistical power on a dose that was
not hypothesized to provide clinically meaningful results. Therefore, no p-value is formally reported for the 0.12 mg/ml dose group.

The study design is included below:

10

Figure 1. ONSET-1 Study Design

In ONSET-1, the 182 subjects were randomly sorted into the four treatment groups following assessment of each subject’s baseline Schirmer’s Score and
EDS. The mean baseline disease characteristics across all treatment groups were generally similar with the exception of the 1.2 mg/ml OC-01 dose group. In
this group, subjects showed lower baseline disease severity, with a higher mean Schirmer’s Score (5.5 mm) relative to the other dose groups (range: 4.5 to 5.2
mm) and a lower mean EDS (53.5 mm) relative to the other dose groups (range: 63.7 to 65.6 mm).

As shown in Figure 2, a statistically significant improvement in Schirmer’s Score at Week 4 was observed in all three doses compared to placebo. The
0.6 mg/ml was associated with a least squares (LS) mean change from baseline Schirmer’s Score of 11.4 mm (95% CI 8.9-13.9; p<0.001). The 1.2 mg/ml
dose group was associated with a LS mean change from baseline Schirmer’s Score of 11.1 mm (95% CI 8.5-13.7; p<0.001). The 0.12 mg/ml dose group was
not formally tested, although it was associated with a LS mean change from baseline Schirmer’s Score of 10.1 mm. Anesthetized Schirmer’s Score results
were similar in the fellow eyes of subjects (p<0.01).

1ANCOVA, Least Squares mean. ITT-observed population. Analysis of Covariance (ANCOVA) is a general linear statistical model which blends analysis of variance and regression. Intent to Treat
(ITT) population analysis is an analysis of all randomized subjects, regardless of whether they received study treatment.

The proportion of subjects who had a change of greater than or equal to (or ≥) 10 mm in Schirmer’s Score from baseline at Week 4 was statistically
significantly higher compared to subjects treated with placebo (vehicle nasal spray; 6 of 43 subjects, 14%) in the 0.6 mg/ml (25 of 46 subjects, 54%; 95% CI
40-69; P<0.001) and 1.2 mg/ml (19 of 40 subjects, 48%; 95% CI 32-63; P=0.001) dose groups. Similar changes from baseline were observed for the OC-01
0.12 mg/ml group (21 of 47 subjects, 45%; 95% CI 30-59; P=0.001).

ONSET-1 had two pre-specified secondary endpoints. The first secondary endpoint was the mean change from baseline to Week 4 in EDS (both eyes). As

shown in Figure 3, a statistically significant reduction in mean EDS from baseline to Week 4 was

11

observed in the 0.6 mg/ml dose group, with a LS mean change from baseline EDS of -19.0 mm (95% CI -26.2 to -11.7; p=0.021). The LS mean change from
baseline EDS to Week 4 for the 1.2 mg/ml dose group was -15.4 mm (95% CI -23.3 to -7.5; p=0.13).
The other secondary endpoint was the change from baseline to Week 3 in mean EDS at five minutes post treatment in the CAE. As shown in Figure 3, a
statistically significant reduction in mean EDS from baseline to Week 3 at five minutes post treatment in CAE was observed in the 0.6 mg/ml dose group,
with a LS mean change from baseline EDS of -16.0 mm (95% CI -21.3 to -10.6; p=0.006). The LS mean change from baseline EDS to Week 3 at five minutes
post  treatment  in  CAE  for  the  1.2  mg/ml  dose  group  was  -18.4  mm  (95%  CI  -24.3  to  -12.5,  *p<0.001).  As  the  first  secondary  outcome  was  statistically
different from placebo only in the 0.6 mg/ml dose group, change in EDS was formally tested in that dose group alone. At Week 3, in the CAE, the LS mean
difference in change from baseline of the EDS between the 0.6 mg/ml dose and placebo groups at five minutes post treatment in CAE was -11.6 mm (95% CI
-20.1 to -3.0; p=0.006). The LS mean difference between the 1.2 mg/ml dose and placebo groups in the change from baseline EDS was -14.0 mm (95% CI
-22.9 to -5.1). While no formal analysis was performed on the 1.2 mg/ml dose group, as this dose group was not statistically significant in the first secondary
endpoint, the nominal p-value was p<0.001.

* Nominal p-value

Sensitivity analyses at ten and fifteen minutes post treatment in the CAE showed similar reductions in EDS as those seen at five minutes post treatment in

subjects treated with OC-01 compared to subjects treated with placebo.

ONSET-1 was not designed or powered to assess corneal fluorescein staining, although we did ultimately measure this as an exploratory analysis using
the National Eye Institute Corneal Fluorescein grading scale. This scale measures corneal staining in five distinct regions on the cornea: central, superior,
inferior, nasal, and temporal, as well as a total score that includes all regions. At Week 4, in the 0.6 mg/ml dose group, total corneal staining (95% CI -2.9 to
-0.2;  p=0.020),  nasal  corneal  staining  (95%  CI  -0.8  to  -0.0;  p=0.026),  and  inferior  corneal  staining  (95%  CI  -0.8  to  -0.1;  p=0.006)  showed  a  statistically
significant benefit as compared to placebo. There was a directional benefit in the 0.6 mg/ml dose group favoring OC-01 in central, superior, and temporal
staining as compared to placebo. We believe that this is the only registrational study to show a statistically significant benefit in corneal fluorescein staining as
soon as Week 4. There was no statistically significant benefit in corneal fluorescein staining in 1.2 mg/ml dose group, although there was a directional benefit
favoring OC-01 in total, central, temporal, inferior, and nasal staining as compared to placebo.

OC-01  was  well  tolerated  at  all  doses  assessed  in  the  study  with  only  one  serious  adverse  event  reported  (in  the  0.6  mg/ml  dose),  which  was  not
suspected to be related to the study drug. The most commonly reported drug-related adverse events in ONSET-1 were non-ocular, whereas reports of ocular
adverse events were few and transient. Only one subject each in the 0.12 mg/ml and 1.2 mg/ml dose groups and two subjects in the 0.6 mg/ml dose group
reported ocular adverse events compared to seven subjects in the placebo group. Of these reported events, reduced visual acuity was reported by one subject
each in the 0.12 mg/ml and 0.6 mg/ml dose groups compared to three subjects in the placebo group, and each instance of reduced visual acuity reported was
resolved by the next visit. No other ocular adverse event was reported by more than one subject.

12

Four subjects discontinued the study due to adverse events. One subject in the 0.6 mg/ml dose group withdrew from the study after one day of treatment
due to dizziness. Three subjects in the 1.2 mg/ml dose group withdrew from the study. The first subject withdrew from the 1.2 mg/ml dose group after one
day of treatment due to sneezing and throat irritation. The other two subjects withdrew from the 1.2 mg/ml dose group after two days of treatment due to (i)
nasopharyngitis and (ii) tinnitus, headache and eyelid edema, respectively. No subjects withdrew from the study after the second day of treatment. The most
commonly reported non-adverse events in ONSET-1 were sneezing and coughing, as shown in Figure 4 below. No subjects in the placebo group reported
either sneezing or cough.

Figure 4. Non-Ocular Adverse Events Occurring in More than One Subject in any Treatment Group

Based on OC-01’s clinical trial results in ONSET-1 and its rapid onset of action, we believe that OC-01, if approved, has the potential to become the

standard of care and redefine how DED is treated for millions of patients.

ZEN: Phase 1 comparative pharmacokinetic clinical trial results

We completed a comparative pharmacokinetic “bridge” trial (ZEN) where we evaluated the relative bioavailability of varenicline administered as a nasal
spray (OC-01) compared to varenicline administered orally (Figure 5). We reported positive top-line results in November 2019. ZEN is a Phase 1, open-label,
randomized,  two-way  crossover  study  to  evaluate  the  relative  bioavailability  of  OC-01  compared  to  varenicline  administered  orally.  The  study  design  is
included below:

Figure 5. ZEN Study Design

The ZEN study was designed to assess the relative bioavailability of varenicline administered intranasally at its highest intended clinical strength (1.2

mg/ml in a 50 microliter nasal spray) compared to varenicline administered as a single oral dose at

13

its  commercially  available  maintenance  oral  tablet  strength  (1  mg).  The  treatment  cohort  consisted  of  22  healthy  volunteers  between  18-65  years  of  age
meeting all other study eligibility criteria who were randomized (Treatment Period 1) to receive an intranasal dose of 0.12 mg OC-01 (50 µL spray of 0.06 mg
into each nostril) or a single 1 mg oral dose of varenicline. Both administrations were delivered while the subject was in an overnight fasted state. Subjects
then returned at least 14 days later (Treatment Period 2) to receive the alternate dose of varenicline that was delivered at Treatment Period 1.

Top-line results (Figure 6) indicate that the relative bioavailability (systemic exposure as defined by adjusted geometric mean AUC0-inf) was 13 times
lower for a single dose of the highest strength of OC-01 nasal spray as compared to a single dose of the highest strength varenicline tablet (7.46 vs. 99.67
h*ng/ml). Maximal concentration (as defined by adjusted geometric mean Cmax) was 14 times lower for a single dose of the highest strength of OC-01 nasal
spray as compared to a single dose of the highest strength varenicline tablet (0.32 vs. 4.55 ng/ml).

The study demonstrated that OC-01 nasal spray was safe and well-tolerated at the doses tested. The number of subjects reporting any treatment-emergent
adverse event (TEAE) was 13 out of 21 (61.9%) after nasal spray administration and 9 out of 22 (40.9%) after oral tablet administration but there were no
reports of serious TEAE noted with either oral or nasal administration. The most common adverse events in the nasal spray group were sneeze in 7 volunteers
(33.3%) and cough in 6 volunteers (28.6%). All events were mild. There were no events of sneeze or cough in the oral tablet administration group. The most
common adverse events in the oral tablet administration group were nausea in 5 volunteers (22.7%) and vomiting in 4 volunteers (18.2%). All events were
mild or moderate in severity. There were no events of nausea or vomiting in the nasal spray administration group.

Figure 6. ZEN Study Results: Mean (+/-SD) Systemic Exposure for Nasal Varenicline and Oral Varenicline

Plasma concentration values below the LLOQ (0.1) are presented as '0' (zero) in the arithmetic mean calculations.
Treatment A: Single oral dose of 1 mg varenicline (Chantix®) administered orally;
Treatment B: Intranasal dose of 0.12 mg OC-01 (varenicline)- delivered as a 50 μL (0.06 mg) spray into each nostril.

This trial could allow us to reference certain FDA conclusions regarding the safety of varenicline tartrate from the Agency’s review of the Chantix NDA.

The FDA has indicated that reliance upon the varenicline tartrate data in our 505(b)(2) NDA submission would be considered scientifically justified if
exposure levels following nasal spray administration of our final clinical formulation are less than or equal to that of Chantix at its approved dose and route of
administration.

MYSTIC: Phase 2 clinical trial results

The MYSTIC study was a randomized, single-masked, vehicle-controlled Phase 2 clinical trial that evaluated the safety and efficacy of OC-01 in 123
subjects with Dry Eye Disease at the Asociación para Evitar la Ceguera (APEC) in Mexico City. APEC is the largest specialized ophthalmology hospital in
North America by patient volume. The study compared two different doses of OC-01 nasal spray (0.6 mg/ml or 1.2 mg/ml) to vehicle control nasal spray
(1:1:1 randomization). The goal of this study was to assess the safety and efficacy of twice daily dosing of OC-01 nasal spray administered for 84 days. The
pre-specified primary endpoint was the assessment of tear production as measured by mean change in Schirmer’s score at Day 84 as compared to vehicle
control. The study design is included below:

Figure 7. MYSTIC Study Design

As shown in Figure 8, a statistically significant improvement in Schirmer’s Score at Day 84 was observed in both doses as compared to placebo. The 0.6
mg/ml  dose  was  associated  with  a  least  squares  (LS)  mean  change  from  baseline  Schirmer’s  Score  of  10.6  mm  (95%  CI  7.9-14.0;  p<0.05),  while  the  1.2
mg/ml  dose  was  associated  with  a  least  squares  (LS)  mean  change  from  baseline  Schirmer’s  Score  of  11.0  mm  (95%  CI  7.9-13.4;  p<0.05). Results  were
statistically significant in both the observed and Last Observation Carried Forward analyses.

Figure 8. MYSTIC: Primary (Sign) Endpoint

OC-01 was well tolerated at all doses assessed in the study with no serious adverse events reported suspected to be related to the study drug. The most
commonly reported drug-related adverse events in MYSTIC were non-ocular, whereas reports of ocular adverse events were few and transient. The number
of subjects reporting non-ocular treatment-emergent adverse event (TEAE) in any dose group was 6 out of 41 (14.6%) in each OC-01 nasal spray dose groups
and 9 out of 41 (22.0%) in the vehicle control group. There were no reports of serious TEAE in the study and no serious adverse events related to study drug
administration. The most common overall adverse events in the nasal spray groups were blurry vision, sneezing, and headache. All events were mild in the
OC-01 nasal spray groups and resolved by the next visit.

ONSET-2: Phase 3 clinical trial

ONSET-2 is a multicenter, dose-ranging, randomized, double-masked, placebo (vehicle)-controlled, Phase 3 clinical trial that evaluated the safety and

efficacy of OC-01 in approximately 750 subjects with DED in the United States The study design is included below:

Figure 10. ONSET-2 Study Design

We expect to report top-line results from this second registrational trial by the end of the second quarter 2020.

Regulatory

We met with the FDA in February 2019 for an end of Phase 2 meeting following the completion of ONSET-1, and the FDA indicated that ONSET-1
could serve as one of the two pivotal safety and efficacy studies required to support a 505(b)(2) NDA filing for OC-01. Based on this feedback, we initiated
ONSET-2, a 750-subject, multicenter, randomized, double-masked, placebo-controlled Phase 3 trial, in July 2019. The objective of this study is to evaluate
the safety and efficacy of OC-01 at 0.6 mg/ml and 1.2 mg/ml doses as compared to placebo on signs and symptoms of DED. Assuming the effect size seen in
ONSET-1, and based on this sample size, the power for each dose for both sign and symptom endpoints would be 99% or greater. This study, in addition to
ONSET-1,  allows  us  to  achieve  the  minimum  number  of  subjects  for  safety-monitoring  purposes.  This  study  has  similar  eligibility  criteria  and  design  to
ONSET-1.

We met with the FDA again in July 2019 for another end of Phase 2 meeting focused on Chemistry, Manufacturing, and Controls (CMC) with regard to
OC-01. The purpose of this meeting was to discuss with the FDA our proposed manufacturing plan that included stability testing, microbiology testing, and
the  size  of  our  drug  product  registration  batches  to  support  NDA  submission.  We  will  continue  to  engage  with  the  FDA  in  an  ongoing  fashion  on
manufacturing topics as we move toward commercialization of OC-01.

Developing OC-01 for additional indications associated with and beyond DED

16

Leveraging our nAChR domain expertise, we continue to explore the development of OC-01 for a number of potential indications and uses associated

with and beyond DED including neurotrophic keratitis, dry eye associated with contact lens intolerance, and ocular surface treatment for refractive surgeries.

Neurotrophic keratitis

Neurotrophic keratitis (NK) is caused when the nerves that supply the cornea cannot function properly. NK reduces sensitivity of the cornea. When the
cornea senses stimulation or pressure, the eyelids will close and tears will be produced to protect the cornea and the eye. Because these nerves do not function
properly in NK, the outer layer of the cornea, called the epithelium, can break down, resulting in an epithelial defect. In more advanced NK, an interior layer
called the cornea stroma can break down as well, resulting in thinning of the cornea. This is called stromal “melting.” In advanced stromal melting, the cornea
can thin to a severe degree, which can result in a hole or opening to the inside of the eye, which can lead to infection and potentially loss of the eye. NK can
lead to a variety of complications, including poor wound healing of the cornea, scarring of the cornea, and loss of vision. There are many different conditions
that can damage the nerves serving the cornea.

A variety of therapies can be used to treat this disorder depending on how far the disorder has progressed in an individual. Most recently, Oxervate, a
recombinant human nerve growth factor, has been approved for the treatment of NK. Unfortunately there are several limitations to this therapy, including that
the product must be refrigerated, administered six times per day at two-hour intervals for eight weeks, and delivered with a pipette that can be cumbersome
for self-administration. Additionally, the cost of the product is more than $90,000 for an eight-week course of therapy.

Normal tear film contains a number of biologically active growth factors including nerve growth factor, epidermal growth factor, transforming growth
factor-beta, hepatocyte growth factor, platelet-derived growth factor, vascular endothelial growth factor, fibroblast growth factor, keratinocyte growth factor,
and insulin-like growth factor. We believe that stimulating natural tear film production twice daily for eight weeks may provide appropriate nourishment and
lubrication that will be beneficial in treating NK. The study design is included below:

Figure 11. OLYMPIA Study Design

Preclinical data for OC-01

As  varenicline  was  previously  studied  by  Pfizer  in  support  of  the  approval  of  NDA  21-928  for  Chantix,  the  appropriate  preclinical  studies  including
toxicology studies in rats, dogs, mice, and monkeys with duration of single dose to 12 months, two-year carcinogenicity studies in mice and rats, standard
battery of genotoxicity studies, reproductive toxicity studies in rats and rabbits, and special toxicology studies were performed.

OC-01 pharmacodynamic assessment

We  conducted  a  non-GLP  pilot  study  to  examine  the  agonist  effects  of  OC-01  at  human  neuronal  nAChRs  subtypes  by  utilizing  Xenopus  oocytes,
overexpressing human α3ß4, α3α5ß4, α4ß2, α4α6ß2 and α7 receptors, and a two-electrode voltage clamp design. Determination of the agonistic effects of
OC-01 at the human α3ß4, α3α5ß4, α4ß2, α4α6ß2 and α7 nAChRs revealed that OC-01 has full agonist activity at the α7 receptor and partial agonist activity
at the α3ß4, α3α5ß4, α4ß2, and α4α6ß2 receptors.

OC-01 toxicology studies

In support of the approval of NDA 21-928, a number of preclinical studies including toxicology studies in rats, dogs, mice, and monkeys with duration of
single dose to 12 months, two-year carcinogenicity studies in mice and rats, standard battery of genotoxicity studies, reproductive toxicity studies in rats and
rabbits, and special toxicology studies were performed by Pfizer. We have also conducted repeat-dose toxicity studies of OC-01 in rats and rabbits for up to
28  days  and  a  26-week  study  in  Dutch  Belted  rabbits  is  ongoing.  This  section  includes  a  summary  of  the  preclinical  experience  with  varenicline  to  date,
although it is not an exhaustive review of all studies performed to support the approval of varenicline.

Repeat-dose, seven-day GLP toxicology studies of OC-01 administered three times daily by intranasal instillation to Sprague-Dawley rats did not result
in  any  mortality,  adverse  clinical  signs,  macroscopic  findings  or  microscopic  findings  in  the  nasal  cavity  or  nasopharynx.  Based  on  these  results,  the  no
observed adverse effect level (NOAEL) was considered to be 3.6 mg/day.

Repeat-dose, seven-day GLP toxicology studies of OC-01 in Dutch Belted Rabbits did not result in any mortality, adverse clinical signs, macroscopic
findings or microscopic findings in the nasal cavity or nasopharynx when given three times daily by intranasal instillation to Dutch Belted rabbits at doses up
to 12.0 mg/day. Based on these results, the NOAEL was considered to be 12.0 mg/day.

Repeat-dose, 28-day GLP toxicology studies of OC-01 administered twice daily by intranasal instillation to Sprague-Dawley rats did not result in any
mortality,  and  no  OC-01-related  adverse  clinical  signs  or  changes  in  bodyweight,  food  consumption,  ophthalmology,  electroretinography  (ERGs)  and
functional observational battery (FOBs) were observed during the study. Administration of OC-01 three times daily for 28 days by intranasal instillation was
well tolerated in the rats at levels up to 0.9 mg/day for the males and 0.18 mg/day for the females. Repeat-dose, 28-day GLP toxicology studies of OC-01 did
not  result  in  any  changes  to  mortality,  clinical  signs,  body  weight,  food  consumption,  nasal  assessment,  ophthalmology  (including  ERG  and  intraocular
pressure),  Schirmer’s  Score,  clinical  pathology,  gross  pathology,  and  histopathology  when  given  two  times  daily  by  intranasal  instillation  to  Dutch  Belted
rabbits at doses up to 8.0 mg/day. Based on these results, the NOAEL was considered to be 8.0 mg/day.

A repeat-dose, six-month GLP toxicology study in Dutch Belted rabbits completed in 2019 evaluated the potential toxicity of OC-01 when administered

twice daily at doses up to 8.0 mg/day with a full report to be provided first half of 2020.

We are also developing a second nAChR agonist product candidate OC-02 (simpinicline), which has the ability to activate the parasympathetic nervous
system in a similar fashion to OC-01. OC-02 shows full agonist activity at the α3ß4, α3α5ß4, α4ß2, and α4α6ß2 receptors and weak agonist activity at the α7
receptor. We have studied OC-02 in two Phase 2b clinical trials (PEARL and RAINIER) for DED. Despite positive efficacy and safety results demonstrated
in both trials, we selected OC-01 as our lead product candidate for DED due to its favorable clinical profile, the potential to leverage the 505(b)(2) regulatory
pathway and significantly lower cost of development. We do not currently intend to pursue FDA approval for OC-02 in DED. However, we believe that the
strong clinical data from both OC-01 and OC-02 validates this class of receptors and our mechanism of action. We believe that targeting the parasympathetic
nervous  system  through  the  use  of  locally  administered  cholinergic  agonists  has  the  potential  to  treat  a  wide  range  of  diseases  and  disorders.  We  have
identified several indications other than DED where we believe

18

OC-02 could provide a meaningful benefit to patients. In certain indications, we believe OC-02 could advance directly into a Phase 2 proof of concept study,
supported by the preclinical and clinical data that we and others have generated in DED as well as other systemic indications. However, we cannot guarantee
that the FDA will permit us to advance OC-02 into a Phase 2 proof of concept study nor can we guarantee that the FDA will grant marketing approval to OC-
02 for the treatment of any indication.

Our development program for OC-02

PEARL: Phase 2b clinical trial results

In July 2018, we reported results from PEARL, a multicenter, dose-ranging, randomized, double-masked, placebo-controlled Phase 2b clinical trial that
evaluated the efficacy and preliminary safety of OC-02 in 165 patients with DED in the United States. The study compared three different doses of OC-02 to
placebo. The first pre-specified co-primary (sign) endpoint was the assessment of tear production as measured by Schirmer’s Score at Day 1 and the second
pre-specified  co-primary  (symptom)  endpoint  was  patient-reported  symptoms  of  DED  as  measured  by  EDS  in  the  CAE  at  Week  2.  The  study  design  is
included below:

Figure 13. PEARL Study Design

The  PEARL  study  was  important  in  validating  that  an  nAChR  agonist  delivered  as  a  nasal  spray  could  improve  the  signs  and  symptoms  of  DED,
endpoints that had not been previously achieved in a single clinical trial by currently marketed therapies in their respective development programs. As shown
in Figure 14, a statistically significant improvement in Schirmer’s Score was observed at Day 1 in all three doses compared to the vehicle-controlled placebo.
The 1.1 mg/ml dose group was associated with a mean change in Schirmer’s Score of 8.6 mm (p=0.0018). A mean change in Schirmer’s Score of 17.1 mm
(p<0.0001) was observed in the 5.5 mg/ml treatment group. A mean change in Schirmer’s Score of 19.3 mm (p<0.0001) was observed in the 11.1 mg/ml
treatment group. The mean change in Schirmer’s Score in the control arm was observed to be 2.6 mm. Also shown in Figure 14, fellow eye results were
similar.

Although the low dose of 1.1 mg/ml of OC-02 was associated with a statistically significant improvement in anesthetized Schirmer’s Score, it did not
yield  a  statistically  significant  difference  in  the  symptom  endpoint  of  EDS  (p=0.4640)  as  shown  in  Figure  15.  A  mean  change  in  EDS  of  -16.5  mm  was
observed in the 5.5 ml/mg dose group (p=0.0067). A mean change in EDS of -19.0 mm was observed in the 11.1 mg/ml dose group (p=0.0006). The control
arm had a mean change in EDS of -6.8 mm.

Figure 15. PEARL: Co-Primary (Symptom) Endpoint

1 ANCOVA primary analysis ITT-observed population

OC-02 was observed to be well tolerated at all doses assessed in the study. Only one serious adverse event was reported and determined to be unrelated to
the study drug. The most common adverse events were typical of nasal sprays (cough, throat irritation, sneezing) and were predominantly mild, transient and
self-limiting.

RAINIER: Phase 2b clinical trial results

In  October  2018,  we  reported  results  from  RAINIER,  a  multicenter,  randomized,  double-masked,  placebo-controlled,  Phase  2b  clinical  trial  that
evaluated the safety and efficacy of 11.1 mg/ml OC-02 in 53 subjects with DED in the United States. At the time of the study, the sample size was limited by
the amount of available OC-02. The study design is included below:

Figure 16. RAINIER Study Design

The study’s sole pre-specified endpoint was the assessment of tear production as measured by anesthetized Schirmer’s Score at Week 4. As shown in
Figure 17, although the results were not statistically significant for the pre-specified endpoint, OC-02 was associated with an increase in tear film production
as measured by an improvement in Schirmer’s Score in the study eye at Week 4 compared to the vehicle-controlled placebo. The OC-02 treatment group had
a mean change in Schirmer’s Score of 10.5 mm (p=0.076). The vehicle-controlled placebo treatment group had a mean change in anesthetized Schirmer’s
Score of 5.7 mm. Also shown in Figure 17, the anesthetized Schirmer’s Score results were statistically significant in the fellow eyes of subjects (p=0.003).

1 ANCOVA, Least Squares mean. ITT-observed population.

OC-02  was  observed  to  be  well  tolerated  at  the  11.1  mg/ml  dose  assessed  in  the  study.  The  most  common  adverse  event  in  all  treatment  groups  was
sneezing,  which  was  temporally  related  to  the  administration  of  the  study  drug  and  resolved  soon  after  administration.  Sneezing  adverse  events  were
characterized as mild to moderate, with no severe adverse events reported.

Preclinical data for OC-02

OC-02 pharmacodynamic assessment

A  non-GLP  pilot  study  was  conducted  to  examine  the  agonist  effects  of  OC-02  at  human  neuronal  nAChRs  subtypes  by  utilizing  Xenopus  oocytes,
overexpressing human α3ß4, α3α5ß4, α4ß2, α4α6ß2 and α7 receptors with a two-electrode voltage clamp design. OC-02 was shown to be a weak agonist at
the α7 receptors, evoking only 24% of the maximal acetylcholine (Ach)-evoked current at the highest dose tested. In contrast, OC-02 evoked two times the
maximal Ach-evoked current at the highest dose tested at the α4ß2 receptor. Moreover, at the α3ß4 and at α3α5ß4 receptors, OC-02 was shown to evoke
approximately 94% of the maximal ACh-evoked currents. OC-02 was shown to have full agonist activity at the α3ß4, α3α5ß4, α4ß2, and α4α6ß2 receptors
and weak agonist activity at the α7 receptor.

OC-02 toxicology studies

Single-dose administration of the 5% dose of OC-02 in New Zealand White rabbits did not result in any test substance-related clinical observations, skin

reactions inside or outside the nose, nasal reactions, gross observations at necropsy or histopathological effects for the seven-day evaluation period.

Repeat-dose, seven-day GLP toxicology studies of OC-02 did not result in any mortality, adverse clinical signs, macroscopic findings or microscopic
findings in the nasal cavity or nasopharynx when given three times daily by intranasal instillation to Sprague-Dawley rats. Based on these results, the NOAEL
was  considered  to  be  6%.  Repeat-dose,  seven-day  GLP  toxicology  studies  of  OC-02  did  not  result  in  any  mortality,  adverse  clinical  signs,  macroscopic
findings or microscopic findings in the nasal cavity or nasopharynx when given three times daily by intranasal instillation to New Zealand White rabbits.
Based on these results, the NOAEL was considered to be 6%.

In repeat-dose, 28-day GLP toxicology studies, OC-02 was administered three times daily in Sprague-Dawley rats. There were no related adverse clinical
signs or changes in bodyweight, food consumption, ophthalmology, ERGs and FOBs determined to be OC-02 related. Administration of OC-02 three times
daily for 28 days by intranasal instillation was well tolerated in rats at levels up to 6%. Repeat-dose, 28-day GLP toxicology studies of OC-02 did not result in
any  changes  to  mortality,  clinical  signs,  body  weight,  food  consumption,  nasal  assessment,  ophthalmology  (including  ERG  and  intraocular  pressure),
Schirmer’s Score, clinical pathology, gross pathology, and histopathology when given three times daily by intranasal instillation to Dutch Belted rabbits at
doses up to 8.0 mg/day. Based on these results, the NOAEL was considered to be 6%.

A repeat dose, six-month GLP toxicology study in Sprague-Dawley rats completed in 2019 evaluated the potential toxicity of OC-02 when administered
twice daily at doses up to 3.98 mg/day. A repeat dose, nine-month GLP toxicology study in New Zealand White rabbits completed in 2019 evaluated the
potential toxicity of OC-02 when administered twice daily at doses up to 13.28 mg/day. A full report will be available in the first half of 2020.

The  biotechnology  and  pharmaceutical  industries  are  characterized  by  rapid  technological  advancement,  significant  competition  and  an  emphasis  on
intellectual property. We face potential competition from many different sources, including major and specialty pharmaceutical and biotechnology companies,
academic research institutions, governmental agencies and public and private research institutions. Any product candidates that we successfully develop and
commercialize  will  compete  with  currently  approved  therapies  and  new  therapies  that  may  become  available  in  the  future.  We  believe  that  the  key
competitive  factors  affecting  the  success  of  any  of  our  product  candidates  will  include  efficacy,  combinability,  safety  profile,  convenience,  cost,  level  of
promotional activity devoted to them and intellectual property protection.

A number of therapies are currently available for the treatment of DED in the United States. The most commonly used treatments for DED in the United
States  are  over-the-counter  eye  drops,  often  referred  to  as  “artificial  tears,”  and  three  FDA-approved  prescription  eye  drop  therapies:  Restasis,  Xiidra  and
Cequa. Artificial tears are intended to supplement insufficient tear production or improve tear film instability, but are primarily saline-based and provide only
temporary  relief.  Restasis  and  Cequa,  both  calcineurin  inhibitor  immunosuppressants,  and  Xiidra,  a  LFA-1  antagonist,  address  chronic  inflammation
associated with DED. Other treatment options include ointments, gels, warm compresses, omega-3 fatty acid supplements and a number of medical devices.
We  are  aware  of  many  other  companies  developing  therapies  for  DED,  including  Aerie  Pharmaceuticals,  Alcon,  Aldeyra  Therapeutics,  Allergan,  Aurinia
Pharmaceuticals, Azura Ophthalmics, Bausch Health (Novaliq), HanAll BioPharma, Johnson & Johnson, Kala Pharmaceuticals, Mitotech, Novartis, Parion
Sciences, ReGenTree, Silk Technologies, Sylentis, TopiVert Pharma, and TearSolutions.

Many  of  the  companies  against  which  we  may  compete  have  significantly  greater  financial  resources  and  expertise  in  research  and  development,
manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. Smaller or early-
stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These
competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient
registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

Sales and Marketing

In light of our stage of development, we have not yet established a commercial organization or distribution capabilities. If our product candidates receive
marketing  approval,  we  plan  to  commercialize  them  in  the  United  States  with  a  focused,  specialty  sales  force  that  could  consist  of  our  own  employees,
outsourced sales professionals, or a hybrid model utilizing both internal and external resources. We believe that this commercial organization at the launch of
OC-01 will consist of approximately 150 to 200 field sales representatives that will call on top-prescribing ophthalmologists and optometrists. We believe an
organization of this size would allow us to reach ECPs that collectively care for more than 80% of patients diagnosed with DED in the United States. Given
the importance of increasing awareness and educating patients with DED, we also anticipate deploying focused direct-to-consumer marketing campaigns for
OC-01. We anticipate that our sales force could also support the commercialization of additional product candidates treating ocular diseases. We would expect
to conduct most of the buildout of this organization following NDA approval of our product candidates. We expect to explore commercialization of OC-01
and potentially other

22

product  candidates  in  certain  markets  outside  the  United  States,  including  the  European  Union,  utilizing  a  variety  of  collaboration,  distribution  and  other
marketing arrangements with one or more third parties.

Manufacturing

We do not currently own or operate facilities for manufacturing, storing, distributing or testing our product candidates. We rely, and expect to continue to
rely for the foreseeable future, on third-party contract manufacturing organizations (CMOs), to manufacture and supply our preclinical and clinical materials
to be used during the development of our product candidates.

The  product  candidate  OC-01  is  a  presentation  of  varenicline,  the  API,  formulated  into  a  nasal  spray  formulation  comprised  of  phosphate  buffer  to
provide appropriate pH control and sodium chloride to obtain suitable osmolality for a nasal spray. We believe the amounts of the API as well as OC-01 we
currently have on hand are sufficient to complete ONSET-2 and ZEN. Additional cGMP API campaigns for varenicline are in process to ensure full supply
for our commercial scale-up, validation and commercial launch activities if OC-01 is approved.

The  product  candidate  OC-02  is  a  presentation  of  simpinicline,  the  API,  formulated  into  a  nasal  spray  formulation  comprised  of  phosphate  buffer  to
provide appropriate pH control and sodium chloride to obtain suitable osmolality for a nasal spray. We believe that we will be able to continue to obtain the
OC-02 API on commercially reasonable terms for any future clinical trials.

Although we currently rely on separate, single CMOs as our sole suppliers for both the non-clinical and clinical supply for the OC-01 API and OC-02
API under cGMP protocols and a single CMO to manufacture OC-01 and OC-02 and to perform analytical testing services, it is our intent to identify and
qualify additional manufacturers to provide OC-01 API and drug product manufacturing and analytical testing services, if possible, prior to submission of the
NDA for OC-01. We expect that we can easily find additional OC-01 API manufacturers as the OC-01 API is a small molecule currently being manufactured
by a number of suppliers throughout the world. Additionally, the drug product manufacturing is a simple compounding and aseptic filling operation that could
also be transferred to additional CMOs as necessary.

Our  third-party  service  providers,  our  third-party  supply  chain  providers,  their  facilities  and  the  OC-01  and  OC-02  used  in  our  clinical  trials  or  for
commercial  sale  are  required  to  be  in  compliance  with  current  Good  Manufacturing  Practices  (cGMP).  The  cGMP  regulations  govern  manufacturing
processes  and  procedures,  including  requirements  relating  to  organization  of  personnel,  buildings  and  facilities,  equipment,  control  of  components  and
packaging containers and closures, production and process controls, packaging and labeling controls, holding and distribution, laboratory controls, records
and  reports,  and  returned  or  salvaged  products.  Product  candidates  used  in  late-stage  clinical  trials  must  be  manufactured  in  accordance  with  cGMP
requirements and satisfy FDA or other authorities’ requirements before any product is approved and before we can manufacture commercial products. Our
third-party manufacturers are also subject to periodic inspections of facilities by the FDA and other authorities, including procedures and operations used in
the testing and manufacture of OC-01 and OC-02 to assess compliance with applicable regulations. Our failure, or the failure to our third-party providers and
supply chain providers, to comply with such statutory and regulatory requirements could subject us to possible legal or regulatory action, including clinical
holds,  fines,  injunctions,  civil  penalties,  delays,  suspension  or  withdrawal  of  approvals,  license  revocation,  suspension  of  production,  warning  letters,  the
seizure or recall of products, operating restrictions and criminal prosecutions. Any of these actions could have a material impact on clinical supplies of OC-01
or our other product candidates. Contract manufacturers at times encounter difficulties involving production yields, quality control and quality assurance, as
well as shortages of qualified personnel.

Intellectual Property

Our success depends in part on our ability to obtain and maintain proprietary protection for our product candidates, technology and know-how, to operate
without infringing the proprietary rights of others and to prevent others from infringing our proprietary rights. Our policy is to seek to protect our proprietary
position by, among other methods, pursuing and obtaining patent protection in the United States and in jurisdictions outside of the United States related to our
proprietary  technology,  inventions,  improvements  and  product  candidates  that  are  important  to  the  development  and  implementation  of  our  business.  Our
patent portfolio is intended to cover our product candidates and components thereof, their methods of use and processes for their manufacture, our proprietary
reagents  and  assays  and  any  other  inventions  that  are  commercially  important  to  our  business.  We  also  rely  on  trade  secret  protection  of  our  confidential
information and know-how relating to our proprietary technology, platforms and product candidates.

Generally, issued patents are granted a term of 20 years from the earliest claimed non-provisional filing date. In certain instances, patent term can be
adjusted to recapture a portion of delay by the U.S. Patent and Trademark Office (USPTO) in examining the patent application (patent term adjustment, or
PTA) or extended to account for term effectively lost as a result of the FDA regulatory review period (patent term extension, or PTE), or both. In addition, we
cannot provide any assurance that any

23

patents will be issued from our pending or future applications or that any issued patents will adequately protect our products or product candidates.

Our patent portfolio as of December 31, 2019 contains approximately 15 issued and unexpired U.S. patents, six pending U.S. patent applications, and
two pending patent cooperation treaty (PCT) applications that are solely owned by us and certain foreign counterparts of a subset of these patents and patent
applications  in  foreign  countries,  including  Australia,  Brazil,  Canada,  China,  Japan,  South  Korea,  Mexico,  and  countries  within  the  European  Patent
Convention  and  the  Eurasian  Patent  Organization.  Owing  to  the  substantial  cost  of  prosecuting  patent  application  internationally,  we  have  selectively  and
strategically abandoned certain of our patent applications in countries with smaller markets and/or a history of weak patent enforcement record. With respect
to  our  candidate  OC-01,  our  patents  and  patent  applications  include  methods  of  treatment.  With  respect  to  our  candidate  OC-02,  our  patents  and  patent
applications cover chemical composition, synthesis and preparation, formulations, and methods of treatment. We continue to seek to maximize the scope of
our patent protection for all our programs. We have five issued U.S. patents relating to methods of treating dry eye disease, increasing tear production, and
improving ocular discomfort using varenicline, as well as pharmaceutical formulations for local nasal administration of varenicline. The patents are U.S. Pat.
Nos.: 9,504,644, 9,504,645, 9,532,944, 9,597,284 and 10,456,396. These patents expire in 2035.

In October 2016, we purchased simpinicline, the compound we refer to as OC-02 and all of the intellectual property rights in and to such compound,
including the related know-how and patents, pursuant to an asset purchase agreement, which was subsequently amended in November 2016 and May 2017 (as
amended, the OC-02 Agreement). Under the OC-02 Agreement we are obligated to make milestone payments of up to an aggregate of $37.0 million upon
achievement of certain development and regulatory milestone events. In March 2018, we made a payment of $1.5 million upon completion of the first of
these milestones. The next milestone payment is payable on the first dosing of a patient in a Phase 3 clinical trial of OC-02. Under the OC-02 Agreement, we
are also obligated to make royalty payments at a mid-single digit percentage rates on net worldwide sales of the covered products. In addition, we are required
to pay 15% of any (i) licensing revenue we receive that is related to OC-02 and (ii) revenue received from the sale of OC-02, up to a maximum aggregate
amount of $10.0 million. We do not currently receive any licensing or sales revenue for OC-02.

We believe that we have certain know-how and trade secrets relating to our technology and product candidates. We rely on trade secrets to protect certain
aspects of our technology related to our current and future product candidates. However, trade secrets can be difficult to protect. We seek to protect our trade
secrets, in part, by entering into confidentiality agreements with our employees, consultants, scientific advisors, service providers, and contractors. We also
seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic
security of our information technology systems.

Licenses

On October 18, 2019, we entered into a non-exclusive patent license agreement (the License Agreement) with Pfizer. Pursuant to the License Agreement,
Pfizer granted us non-exclusive rights under Pfizer’s patent rights covering varenicline tartrate and related salts thereof, including U.S. Patent Nos.: 7,265,119
and 6,890,927 to develop, manufacture, and commercialize our OC-01 varenicline product candidate for the treatment of any ophthalmic disease or condition
via nasal administration in the United States.

Under the terms of the agreement, we made an upfront payment to Pfizer of $5.0 million. If we successfully commercialize OC-01, we may be required
to pay to Pfizer a single milestone payment in the very low double-digit millions if we achieve a specified level of annual aggregate net sales of OC-01 within
a  specified  timeframe.  We  will  also  be  required  to  pay  Pfizer  tiered  royalties  on  net  sales  of  OC-01  by  us,  our  affiliates,  or  sublicensees,  at  percentages
ranging from the mid-single digits to the mid-teens. Our royalty obligation to Pfizer will commence upon first commercial sale of OC-01 and will expire upon
the later of (a) the expiration of all regulatory or data exclusivity granted to Pfizer in connection with varenicline in the United States; and (b) the expiration
or abandonment of the last valid claims of the licensed patents.

The License Agreement will terminate when all claims in all the licensed patents expire or are irretrievably abandoned, which we expect to be no later
than August 2022. The License Agreement may be terminated earlier by us for any reason, or by Pfizer upon 60 days’ written notice for our uncured material
breach (30 days in the case of non-payment), or immediately upon our insolvency.

Regulatory Pathway

Varenicline tartrate is currently marketed by Pfizer in the United States under the trade name Chantix as an aid to smoking cessation treatment. We have

filed an Investigational New Drug Application (IND) with the FDA to study varenicline for the

24

treatment of the signs and symptoms of dry eye disease and intend to submit a 505(b)(2) NDA, relying in part upon certain FDA conclusions regarding the
safety of varenicline from the Agency’s review of the Chantix NDA.

Government Regulation

Government  authorities  in  the  United  States  at  the  federal,  state  and  local  level  and  in  other  countries  regulate,  among  other  things,  the  research,
development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval
monitoring and reporting, marketing and export and import of drug products. Generally, before a new drug can be marketed, considerable data demonstrating
its quality, safety and efficacy must be obtained, organized into a format specific for each regulatory authority, submitted for review and approved by the
regulatory authority.

U.S. Drug Regulation

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (FDCA) and its implementing regulations. FDA approval
is required before any new unapproved drug or dosage form, including a new use of a previously approved drug, can be marketed in the United States. Drugs
also are subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with
appropriate federal, state, local and foreign statutes and regulations requires the expenditure of substantial time and financial resources. Failure to comply
with the applicable U.S. requirements at any time during the product development process, approval process or post-marketing may subject an applicant to
administrative or judicial sanctions. These sanctions could include, among other actions, the FDA’s refusal to approve pending applications, withdrawal of an
approval,  a  clinical  hold,  untitled  or  warning  letters,  voluntary  or  mandatory  product  recalls  or  market  withdrawals,  product  seizures,  total  or  partial
suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement and civil or criminal fines or penalties.
Any agency or judicial enforcement action could have a material adverse effect on our business, market acceptance of our products, and our reputation.

Our product candidates are considered small molecule drugs and must be approved by the FDA through the NDA process before they may be legally

marketed in the United States. The process generally involves the following:

•

•

•

•

•

•

•

•

•

•

completion of extensive preclinical studies in accordance with applicable regulations, including studies conducted in accordance with
good laboratory practice (GLP) requirements;

submission to the FDA of an investigational new drug application (IND), which must become effective before human clinical trials may
begin and must be updated annually or when significant changes are made;

approval by an independent institutional review board (IRB) or independent ethics committee at each clinical trial site before each trial
may be initiated;

performance of adequate and well-controlled human clinical trials in accordance with applicable IND regulations, good clinical practice
(GCP) requirements and other clinical trial-related regulations to establish substantial evidence of the safety and efficacy of the
investigational product for each proposed indication;

submission to the FDA of an NDA;

a determination by the FDA within 60 days of its receipt of an NDA to accept the filing for review;

satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities where the drug will be produced to
assess compliance with current good manufacturing practice (cGMP) requirements, and of selected clinical investigational sites to assess
compliance with GCD;

potential FDA audit of the preclinical study and/or clinical trial sites that generated the data in support of the NDA filing;

payment of user fees for FDA review of the NDA;

FDA review and approval of the NDA, including consideration of the views of any FDA advisory committee, prior to any commercial
marketing or sale of the drug in the United States; and

25

•

compliance with any post-approval requirements, including the potential requirement to implement a Risk Evaluation and Mitigation
Strategy (REMS), and the potential requirement to conduct post-approval studies.

The data required to support an NDA are generated in two distinct developmental stages: preclinical and clinical. The preclinical and clinical testing and
approval process can take many years and the actual time required to obtain approval, if any, may vary substantially based upon the type, complexity and
novelty of the product or condition being treated.

Preclinical Studies and IND Submission

Before  testing  any  drug  product  candidate  in  humans,  the  product  candidate  must  undergo  rigorous  preclinical  testing.  The  preclinical  developmental
stage generally involves laboratory evaluations of drug chemistry, formulation and stability, as well as in vitro and animal studies to assess the potential for
adverse  events  and  in  some  cases  to  establish  a  rationale  for  therapeutic  use.  The  conduct  of  preclinical  studies  is  subject  to  federal  regulations  and
requirements, including GLP regulations for safety/toxicology studies. An IND is a request for authorization from the FDA to administer an investigational
product to humans, and must become effective before human clinical trials may begin.

An IND sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data, any available clinical data or
literature  and  plans  for  clinical  studies,  among  other  things,  to  the  FDA  as  part  of  an  IND.  Some  long-term  preclinical  testing,  such  as  animal  tests  of
reproductive adverse events and carcinogenicity, may continue after the IND is submitted. An IND automatically becomes effective 30 days after receipt by
the FDA, unless before that time the FDA raises concerns or questions related to one or more proposed clinical trials and places the trial on clinical hold. In
such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. As a result, submission of an IND may
not result in the FDA allowing clinical trials to commence. A separate submission to an existing IND must also be made for each successive clinical trial
conducted during product development along with any subsequent changes to the investigational plan.

Clinical Trials

The clinical stage of development involves the administration of the investigational product to healthy volunteers or patients under the supervision of
qualified investigators, generally physicians not employed by or under the trial sponsor’s control, in accordance with GCP requirements, which include the
requirement that all research subjects provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols
detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria and the parameters to be used to
monitor subject safety and assess efficacy. Each protocol, and any subsequent amendments to the protocol, must be submitted to the FDA as part of the IND.
Furthermore, each clinical trial must be reviewed and approved by an IRB for each institution at which the clinical trial will be conducted to ensure that the
risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed
consent form that must be provided to each clinical trial subject or his or her legal representative, and must monitor the clinical trial until completed. There
also  are  requirements  governing  the  reporting  of  ongoing  clinical  trials  and  completed  clinical  trial  results  to  public  registries,  including  the  website
maintained by the U.S. National Institutes of Health, ClinicalTrials.gov.

A sponsor who wishes to conduct a clinical trial outside of the United States may, but need not, obtain FDA authorization to conduct the clinical trial
under an IND. If a foreign clinical trial is not conducted under an IND, the sponsor may submit data from the clinical trial to the FDA in support of an NDA.
The FDA will accept a well-designed and well-conducted foreign clinical trial not conducted under an IND if the trial was conducted in accordance with GCP
requirements and the FDA is able to validate the data through an onsite inspection, if deemed necessary, and the practice of medicine in the foreign country is
consistent with the United States.

Clinical trials in the United States generally are conducted in three sequential phases, known as Phase 1, Phase 2 and Phase 3. Although the phases are

usually conducted sequentially, they may overlap or be combined.

26

•

•

•

Phase 1 clinical trials generally involve a small number of healthy volunteers or disease-affected patients who are initially exposed to a
single dose and then multiple doses of the product candidate. The primary purpose of these clinical trials is to assess the metabolism,
pharmacologic action, tolerability and safety of the drug in humans, the side effects associated with increasing doses, and if possible, to
gain early evidence on effectiveness.

Phase 2 clinical trials generally involve studies in disease-affected patients to determine the dose and dosing schedule required to produce
the desired benefits. At the same time, safety and further pharmacokinetic and pharmacodynamic information is collected, possible
adverse effects and safety risks are identified and a preliminary evaluation of efficacy is conducted.

Phase 3 clinical trials generally involve a large number of patients at multiple sites and are designed to provide the data necessary to
demonstrate the safety and effectiveness of the product for its intended use and to establish the overall benefit/risk relationship of the
product to provide an adequate basis for product approval. These trials may include comparisons with placebo and/or other comparator
treatments. The duration of treatment is often extended to mimic the actual use of a product during marketing.

Post-approval  trials,  sometimes  referred  to  as  Phase  4  clinical  trials,  may  be  conducted  after  initial  marketing  approval.  These  trials  are  used  to  gain
additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, the FDA may mandate the performance of
Phase 4 clinical trials as a condition of approval of an NDA.

Progress  reports  detailing  the  results  of  the  clinical  trials,  among  other  information,  must  be  submitted  at  least  annually  to  the  FDA  and  written  IND
safety reports must be submitted to the FDA and the investigators for serious and unexpected suspected adverse events, findings from other studies suggesting
a significant risk to humans exposed to the drug, findings from animal or in vitro testing that suggest a significant risk for human subjects and any clinically
important increase in the rate of a serious suspected adverse reaction over that listed in the protocol.

Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA or the sponsor may suspend
or terminate a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable
health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance
with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients. Additionally, some clinical trials are overseen by an
independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or committee. This group provides
authorization for whether a trial may move forward at designated check-points based on access to certain data from the trial. Concurrent with clinical trials,
companies usually complete additional animal safety studies and also must develop additional information about the chemistry and physical characteristics of
the drug as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing
process must be capable of consistently producing quality batches of our product candidates. Additionally, appropriate packaging must be selected and tested
and stability studies must be conducted to demonstrate that our product candidates do not undergo unacceptable deterioration over their labeled shelf life.

NDA Review

Following completion of clinical trials, data are analyzed to assess whether the investigational product is safe and effective for the proposed indicated use
or uses. The results of preclinical studies and clinical trials are then submitted to the FDA as part of an NDA, along with proposed labeling, chemistry and
manufacturing information in a request for approval to market the drug for one or more specified indications. The application must include both negative and
ambiguous results of preclinical studies and clinical trials, as well as positive findings. Data may come from company-sponsored clinical trials intended to test
the safety and efficacy of a product’s use or from a number of alternative sources, including studies initiated by investigators. To support marketing approval,
the data submitted must be sufficient in quality and quantity to establish the safety and efficacy of the investigational product to the satisfaction of FDA. FDA
approval of an NDA must be obtained before a drug may be marketed in the United States.

Under the Prescription Drug User Fee Act (PDUFA), as amended, each NDA must be accompanied by an application user fee. FDA adjusts the PDUFA
user fees on an annual basis. PDUFA also imposes an annual program fee for each marketed human drug. Fee waivers or reductions are available in certain
circumstances, including a waiver of the application fee for the first application filed by a qualifying small business. Additionally, no user fees are assessed on
NDAs for products designated as orphan drugs, unless the product also includes a non-orphan indication.

The FDA reviews all submitted NDAs before it accepts them for filing to determine if they are sufficiently complete to permit a substantive review, and
the FDA may request additional information rather than accepting the NDA for filing. The FDA must make a decision on accepting an NDA for filing within
60 days of receipt. Once the submission is accepted for filing, the

27

FDA begins an in-depth review of the NDA. Under PDUFA, the FDA has agreed to certain performance goals in the review of NDAs through a two-tiered
classification  system,  standard  review  and  priority  review.  According  to  PDUFA  performance  goals,  the  FDA  endeavors  to  review  applications  subject  to
standard  review  within  ten  to  twelve  months,  whereas  the  FDA’s  goal  is  to  review  priority  review  applications  within  six  to  eight  months,  depending  on
whether the drug is a new molecular entity. The FDA does not always meet its PDUFA goal dates for standard and priority NDAs, and the review process is
often extended by FDA requests for additional information or clarification.

Before approving an NDA, the FDA will conduct a pre-approval inspection of the manufacturing facilities for the new product to determine whether they
comply  with  cGMP  requirements.  The  FDA  will  not  approve  the  product  unless  it  determines  that  the  manufacturing  processes  and  facilities  are  in
compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. The FDA also may audit data
from  clinical  trials  to  ensure  compliance  with  GCP  requirements.  Additionally,  the  FDA  may  refer  applications  for  novel  drug  products  or  drug  products
which  present  difficult  questions  of  safety  or  efficacy  to  an  advisory  committee,  typically  a  panel  that  includes  clinicians  and  other  experts,  for  review,
evaluation  and  a  recommendation  as  to  whether  the  application  should  be  approved  and  under  what  conditions,  if  any.  The  FDA  is  not  bound  by
recommendations of an advisory committee, but it considers such recommendations when making decisions on approval. The FDA also closely analyzes the
clinical  trial  data,  which  could  result  in  extensive  discussions  between  the  FDA  and  the  applicant  during  the  review  process.  After  the  FDA  evaluates  an
NDA, it will issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug with specific prescribing
information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete and the application will not be
approved in its present form. A Complete Response Letter usually describes all of the specific deficiencies in the NDA identified by the FDA. The Complete
Response Letter may require additional clinical data, including the potential requirement to conduct additional pivotal Phase 3 clinical trial(s) and/or other
significant and time-consuming requirements related to clinical trials, or to conduct additional preclinical studies or manufacturing changes. If a Complete
Response Letter is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter, or withdraw the application.
Even if such data and information are submitted, the FDA may decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical
trials are not always conclusive and the FDA may interpret data differently than we interpret the same data.

Section 505(b)(2) New Drug Applications

Section 505 of the FDCA describes three types of marketing applications that may be submitted to the FDA to request marketing authorization for a new
drug.  A  505(b)(1)  NDA  is  an  application  that  contains  full  reports  of  investigations  of  safety  and  efficacy  conducted  by  or  on  behalf  of  the  applicant.  A
505(b)(2) NDA is an application that contains full reports of investigations of safety and efficacy but where at least some of the information required for
approval comes from investigations that were not conducted by or for the applicant and for which the applicant has not obtained a right of reference or use
from the person by or for whom the investigations were conducted. This regulatory pathway enables the applicant to rely, in part, on the FDA’s prior findings
of safety and efficacy for an existing product, or published literature, in support of its application.

505(b)(2)  NDAs  often  provide  an  alternate  path  to  FDA  approval  for  new  or  improved  formulations,  new  routes  of  administration,  or  new  uses  of
previously  approved  products.  If  the  Section  505(b)(2)  applicant  can  establish  that  reliance  on  the  FDA’s  prior  findings  of  safety  and/or  effectiveness  is
scientifically appropriate, it may eliminate the need to conduct certain preclinical or clinical studies of the new product. The FDA may also require companies
to perform additional studies or measurements to support the change from the approved product. The FDA may then approve the new product candidate for
all,  or  some,  of  the  indications  for  which  the  referenced  product  has  been  approved,  as  well  as  for  any  new  indication  sought  by  the  Section  505(b)(2)
applicant.

To the extent that the Section 505(b)(2) applicant is relying on the FDA’s prior findings of safety or effectiveness for an already approved product, the
applicant is required to provide a certification to the FDA concerning each patent listed for the approved product in the FDA’s Approved Drug Products with
Therapeutic Equivalence Evaluations (the Orange Book). Depending on the type of certification, approval of a 505(b)(2) NDA can be stalled until all the
listed patents claiming the referenced product have expired, until any non-patent exclusivity, listed in the Orange Book for the reference product, such as the 5
years  of  exclusivity  for  obtaining  approval  of  a  new  chemical  entity  has  expired,  and,  in  the  case  of  a  Paragraph  IV  certification  and  subsequent  patent
infringement suit brought by the holder of the listed patent, until the earlier of 30 months, settlement of the lawsuit or a decision in the infringement case that
is favorable to the Section 505(b)(2) applicant.

Post-Approval Requirements

Following approval of a new product, the product is subject to continuing regulation by the FDA, including, among other things, requirements relating to
facility registration and drug listing monitoring and record-keeping adverse event and other periodic reporting, product sampling and distribution, and product
promotion and advertising including restrictions on promoting

28

drugs for unapproved uses or patient populations, known as “off-label use,” and limitations on industry-sponsored scientific and educational activities. The
FDA  strictly  regulates  marketing,  labeling,  advertising  and  promotion  of  products  that  are  placed  on  the  market.  Drugs  may  be  promoted  only  for  the
approved  indications  and  in  accordance  with  the  provisions  of  the  approved  label.  The  FDA  and  other  agencies  actively  enforce  the  laws  and  regulations
prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability.

Although  physicians  may  prescribe  legally  available  drugs  for  off-label  uses,  manufacturers  may  not  market  or  promote  such  uses.  Prescription  drug
promotional materials must be submitted to the FDA in conjunction with their first use or first publication. Further, if there are any modifications to the drug,
including changes in indications, labeling or manufacturing processes or facilities, the applicant may be required to submit and obtain FDA approval of a new
NDA or NDA supplement, which may require the development of additional data or preclinical studies and clinical trials.

The FDA may also place other conditions on approvals including the requirement for REMS, to assure the safe use of the product. If the FDA concludes
that a REMS is needed, the NDA sponsor must submit a proposed REMS. The FDA will not approve the FDA without an approved REMS, if required. A
REMS  could  include  medication  guides,  physician  communication  plans  or  elements  to  assure  safe  use,  such  as  restricted  distribution  methods,  patient
registries  and  other  risk  minimization  tools.  Any  of  these  limitations  on  approval  or  marketing  could  restrict  the  commercial  promotion,  distribution,
prescription or dispensing of products. Product approvals may be withdrawn for non-compliance with regulatory standards or if problems occur following
initial marketing.

FDA regulations require that products be manufactured in specific approved facilities and in accordance with cGMP regulations. We rely, and expect to
continue  to  rely,  on  third  parties  for  the  production  of  clinical  and  commercial  quantities  of  our  products  in  accordance  with  cGMP  regulations.  These
manufacturers must comply with cGMP regulations that require, among other things, quality control and quality assurance, the maintenance of records and
documentation, and the obligation to investigate and correct any deviations from cGMP. Manufacturers and other entities involved in the manufacture and
distribution of approved drugs are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced
inspections  by  the  FDA  and  certain  state  agencies  for  compliance  with  cGMP  requirements  and  other  laws.  Accordingly,  manufacturers  must  continue  to
expend time, money and effort in the area of production and quality control to maintain cGMP compliance. The discovery of violative conditions, including
failure  to  conform  to  cGMP  regulations,  could  result  in  enforcement  actions,  and  the  discovery  of  problems  with  a  product  after  approval  may  result  in
restrictions on a product, its manufacturer or the NDA holder, including recalls.

The FDA may withdraw approval of a product if compliance with regulatory requirements and standards is not maintained or if problems occur after the
product  reaches  the  market.  Corrective  action  could  delay  drug  distribution  and  require  significant  time  and  financial  expenditures.  Later  discovery  of
previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to
comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or
clinical studies to assess new safety risks or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences
include, among other things:

•

•

•

•

•

•

restrictions on the marketing or manufacturing of the product, suspension of the approval, complete withdrawal of the product from the
market, or product recalls;

fines, warning letters, or holds on post-approval clinical trials;

refusal of the FDA to approve pending applications or supplements to approved applications;

suspension or revocation of product approvals;

product seizure or detention, or refusal to permit the import or export of products; or

injunctions or the imposition of civil or criminal penalties.

Other Regulatory Matters

Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and
foreign  jurisdictions  in  which  they  conduct  their  business.  Manufacturing,  sales,  promotion  and  other  activities  following  product  approval  are  subject  to
regulation by numerous regulatory authorities in the United States in addition to the FDA, including CMS, other divisions of the Department of Health and
Human Services, the Department of Justice, the

29

Drug  Enforcement  Administration,  the  Consumer  Product  Safety  Commission,  the  Federal  Trade  Commission,  the  Occupational  Safety  &  Health
Administration, the Environmental Protection Agency, and state and local governments.

For  example,  in  the  United  States,  sales,  marketing  and  scientific  and  educational  programs  also  must  comply  with  state  and  federal  fraud  and  abuse

•

laws, false claims laws, transparency laws, government price reporting, and health information privacy and security laws. These laws include the following:
the federal Anti-Kickback Statute, which makes it illegal for any person, including a prescription drug manufacturer (or a party acting on
its behalf), to knowingly and willfully solicit, receive, offer or pay any remuneration that is intended to induce or reward referrals,
including the purchase, recommendation, order or prescription of a particular drug, for which payment may be made under a federal
healthcare program, such as Medicare or Medicaid. Moreover, the ACA provides that the government may assert that a claim including
items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the
civil False Claims Act;

•

•

•

•

•

•

•

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

the Federal Health Insurance Portability and Accountability Act of 1996 (HIPAA) prohibits, among other things, executing or attempting
to execute a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;

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

federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially
harm consumers;

the FDCA, which prohibits, among other things, the adulteration or misbranding of drugs, biologics and medical devices;

the federal Physician Payments Sunshine Act requires applicable manufacturers of covered drugs, devices, biologics and medical supplies
for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to
annually report to CMS information regarding payments and other transfers of value to physicians and teaching hospitals as well as
information regarding ownership and investment interests held by physicians and their immediate family members; and

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws which may apply to sales or marketing
arrangements and claims involving healthcare items or services reimbursed by non- governmental third-party payors, including private
insurers, state laws that require biotechnology companies to comply with the biotechnology industry’s voluntary compliance guidelines
and the relevant compliance guidance promulgated by the federal government and may require drug manufacturers to report information
related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures, state laws that
require biotechnology companies to report information on the pricing of certain drug products, and state and foreign laws that govern the
privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are
not preempted by HIPAA, thus complicating compliance efforts.

Pricing and rebate programs must also comply with the Medicaid rebate requirements of the U.S. Omnibus Budget Reconciliation Act of 1990 and more
recent requirements in the ACA. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration,
additional laws and requirements apply. Products must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging
Act. Manufacturing, sales, promotion and other activities also are potentially subject to federal and state consumer protection and unfair competition laws.

30

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage

and security requirements intended to prevent the unauthorized sale of pharmaceutical products.

The  failure  to  comply  with  any  of  these  laws  or  regulatory  requirements  subjects  firms  to  possible  legal  or  regulatory  action.  Depending  on  the
circumstances,  failure  to  meet  applicable  regulatory  requirements  can  result  in  significant  civil,  criminal  and  administrative  penalties,  including  damages,
fines,  disgorgement,  individual  imprisonment,  exclusion  from  participation  in  government  funded  healthcare  programs,  such  as  Medicare  and  Medicaid,
integrity oversight and reporting obligations, contractual damages, reputational harm, diminished profits and future earnings, injunctions, requests for recall,
seizure  of  products,  total  or  partial  suspension  of  production,  denial  or  withdrawal  of  product  approvals  or  refusal  to  allow  a  firm  to  enter  into  supply
contracts, including government contracts.

U.S. Patent-Term Restoration and Marketing Exclusivity

Depending  upon  the  timing,  duration  and  specifics  of  FDA  approval  of  any  future  product  candidates,  some  of  our  U.S.  patents  may  be  eligible  for
limited  patent  term  extension  under  the  Hatch-Waxman  Act.  The  Hatch-Waxman  Act  permits  restoration  of  the  patent  term  of  up  to  five  years  as
compensation  for  patent  term  lost  during  product  development  and  FDA  regulatory  review  process.  Patent-term  restoration,  however,  cannot  extend  the
remaining  term  of  a  patent  beyond  a  total  of  14  years  from  the  product’s  approval  date.  The  patent-term  restoration  period  is  generally  one-half  the  time
between  the  effective  date  of  an  IND  or  the  issue  date  of  the  patent,  whichever  is  later,  and  the  submission  date  of  an  NDA  plus  the  time  between  the
submission date of an NDA or the issue date of the patent, whichever is later, and the approval of that application, except that the review period is reduced by
any time during which the applicant failed to exercise due diligence. Only one patent applicable to an approved drug is eligible for the extension and the
application for the extension must be submitted prior to the expiration of the patent. The USPTO, in consultation with the FDA, reviews and approves the
application for any patent term extension or restoration. In the future, we may apply for restoration of patent term for our currently owned or licensed patents
to  add  patent  life  beyond  its  current  expiration  date,  depending  on  the  expected  length  of  the  clinical  trials  and  other  factors  involved  in  the  filing  of  the
relevant NDA.

Market exclusivity provisions under the FDCA also can delay the submission or the approval of certain applications. The FDCA provides a five-year
period of non-patent marketing exclusivity within the United States to the first applicant to gain approval of an NDA for a new chemical entity. A drug is a
new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible
for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an abbreviated new drug application (ANDA) or a
505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of reference to all the
data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement.
The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA if new clinical investigations,
other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application,
for example, new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the conditions of use associated with the new
clinical  investigations  and  does  not  prohibit  the  FDA  from  approving  ANDAs  for  drugs  containing  the  original  active  agent.  Five-year  and  three-year
exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a
right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

European Union Drug Development

Similar to the United States, the various phases of preclinical and clinical research in the European Union are subject to significant regulatory controls.
Although the European Union Clinical Trials Directive 2001/20/EC has sought to harmonize the EU clinical trials regulatory framework, setting out common
rules  for  the  control  and  authorization  of  clinical  trials  in  the  EU,  the  EU  Member  States  have  transposed  and  applied  the  provisions  of  the  Directive
differently.  This  has  led  to  significant  variations  in  the  member  state  regimes.  Under  the  current  regime,  before  a  clinical  trial  can  be  initiated  it  must  be
approved in each of the EU countries where the trial is to be conducted by two distinct bodies: the National Competent Authority (NCA) and one or more
Ethics Committees (ECs). Under the current regime all suspected unexpected serious adverse reactions to the investigated drug that occur during the clinical
trial have to be reported to the NCA and ECs of the Member State where they occurred.

The EU clinical trials legislation currently is undergoing a transition process mainly aimed at harmonizing and streamlining clinical-trial authorization,
simplifying adverse-event reporting procedures, improving the supervision of clinical trials and increasing their transparency. Recently enacted Clinical Trials
Regulation  EU  No  536/2014  ensures  that  the  rules  for  conducting  clinical  trials  in  the  EU  will  be  identical.  In  the  meantime,  Clinical  Trials  Directive
2001/20/EC continues to govern all clinical trials performed in the EU.

European Union Drug Review and Approval

In the European Economic Area (EEA), which is comprised of the 27 Member States of the European Union (including Norway and excluding Croatia),
Iceland and Liechtenstein, medicinal products can only be commercialized after obtaining a Marketing Authorization (MA). There are two types of marketing
authorizations.

•

•

The Community MA is issued by the European Commission through the Centralized Procedure, based on the opinion of the Committee
for Medicinal Products for Human Use (CHMP) of the EMA, and is valid throughout the entire territory of the EEA. The Centralized
Procedure is mandatory for certain types of products, such as biotechnology medicinal products, orphan medicinal products, advanced-
therapy medicines such as gene-therapy, somatic cell-therapy or tissue-engineered medicines and medicinal products containing a new
active substance indicated for the treatment of HIV, AIDS, cancer, neurodegenerative disorders, diabetes, auto-immune and other immune
dysfunctions and viral diseases. The Centralized Procedure is optional for products containing a new active substance not yet authorized
in the EEA, or for products that constitute a significant therapeutic, scientific or technical innovation or which are in the interest of public
health in the European Union.

National MAs, which are issued by the competent authorities of the Member States of the EEA and only cover their respective territory,
are available for products not falling within the mandatory scope of the Centralized Procedure. Where a product has already been
authorized for marketing in a Member State of the European Union, this National MA can be recognized in another Member States
through the Mutual Recognition Procedure. If the product has not received a National MA in any Member State at the time of application,
it can be approved simultaneously in various Member States through the Decentralized Procedure. Under the Decentralized Procedure an
identical dossier is submitted to the competent authorities of each of the Member States in which the MA is sought, one of which is
selected by the applicant as the Reference Member State (RMS). The competent authority of the RMS prepares a draft assessment report,
a draft summary of the product characteristics (SPC), and a draft of the labeling and package leaflet, which are sent to the other Member
States (referred to as the Member States Concerned) for their approval. If the Member States Concerned raise no objections, based on a
potential serious risk to public health, to the assessment, SPC, labeling or packaging proposed by the RMS, the product is subsequently
granted a national MA in all the Member States (i.e., in the RMS and the Member States Concerned).

Under the above described procedures, before granting the MA, EMA or the competent authorities of the Member States of the European Union make an
assessment of the risk-benefit balance of the product on the basis of scientific criteria concerning its quality, safety and efficacy. Similar to the U.S. patent
term-restoration, Supplementary Protection Certificates (SPCs) serve as an extension to a patent right in Europe for up to five years. SPCs apply to specific
pharmaceutical products to offset the loss of patent protection due to the lengthy testing and clinical trials these products require prior to obtaining regulatory
marketing approval.

Coverage and Reimbursement

Sales  of  our  products  will  depend,  in  part,  on  the  extent  to  which  our  products  will  be  covered  by  third-party  payors,  such  as  government  health
programs,  commercial  insurance,  and  managed  healthcare  organizations.  There  is  significant  uncertainty  related  to  third-party  payor  coverage  and
reimbursement of newly approved products. In the United States, for example, principal decisions about reimbursement for new products are typically made
by CMS. CMS decides whether and to what extent a new product will be covered and reimbursed under Medicare, and private third-party payors often follow
CMS’s  decisions  regarding  coverage  and  reimbursement  to  a  substantial  degree.  However,  no  uniform  policy  of  coverage  and  reimbursement  for  drug
products exists. Accordingly, decisions regarding the extent of coverage and amount of reimbursement to be provided for any of our products will be made on
a payor-by-payor basis.

Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the
prices  charged  for  medical  products.  Further,  such  payors  are  increasingly  challenging  the  price,  examining  the  medical  necessity  and  reviewing  the  cost
effectiveness of medical product candidates. There may be especially significant delays in obtaining coverage and reimbursement for newly approved drugs.
Third-party payors may limit coverage to specific product candidates on an approved list, known as a formulary, which might not include all FDA-approved
drugs for a particular indication. We may need to conduct expensive pharmaco-economic studies to demonstrate the medical necessity and cost effectiveness
of our products. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and
clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained.

32

In addition, in most foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing
drug pricing and reimbursement vary widely from country to country. For example, the European Union 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 any of our products. Historically, products launched
in the European Union do not follow price structures of the United States and generally prices tend to be significantly lower.

Healthcare Reform

The United States government, state legislatures, and foreign governments have shown significant interest in implementing cost containment programs to
limit the growth of government-paid healthcare costs, including price-controls, restrictions on reimbursement, and requirements for substitution of generic
products for branded prescription drugs. For example, in March 2010, the Patient Protection and Affordable Care Act of 2010, as amended by the Health Care
and  Education  Reconciliation  Act  of  2010  (collectively,  the  ACA),  was  passed  which  substantially  changed  the  way  healthcare  is  financed  by  both  the
government and private insurers, and significantly impacts the U.S. pharmaceutical industry. The ACA contains provisions that may reduce the profitability
of  drug  products  through  increased  rebates  for  drugs  reimbursed  by  Medicaid  programs,  extension  of  Medicaid  rebates  to  Medicaid  managed  care  plans,
mandatory  discounts  for  certain  Medicare  Part  D  beneficiaries  and  annual  fees  based  on  pharmaceutical  companies’  share  of  sales  to  federal  health  care
programs. The Medicaid Drug Rebate Program requires pharmaceutical manufacturers to enter into and have in effect a national rebate agreement with the
HHS Secretary as a condition for states to receive federal matching funds for the manufacturer’s outpatient drugs furnished to Medicaid patients. The ACA
made  several  changes  to  the  Medicaid  Drug  Rebate  Program,  including  increasing  pharmaceutical  manufacturers’  rebate  liability  by  raising  the  minimum
basic Medicaid rebate on most branded prescription drugs from 15.1% of average manufacturer price (AMP), to 23.1% of AMP and adding a new rebate
calculation for “line extensions” (i.e., new formulations, such as extended release formulations) of solid oral dosage forms of branded products, as well as
potentially impacting their rebate liability by modifying the statutory definition of AMP. The ACA also expanded the universe of Medicaid utilization subject
to drug rebates by requiring pharmaceutical manufacturers to pay rebates on Medicaid managed care utilization and by enlarging the population potentially
eligible for Medicaid drug benefits. Effective April 1, 2020, Medicaid rebate liability will be expanded to include the territories of the United States as well.
Additionally, for a drug product to receive federal reimbursement under the Medicaid or Medicare Part B programs or to be sold directly to U.S. government
agencies, the manufacturer must extend discounts to entities eligible to participate in the 340B drug pricing program. The required 340B discount on a given
product is calculated based on the AMP and Medicaid rebate amounts reported by the manufacturer.

Some of the provisions of the ACA have yet to be implemented, and there have been judicial, Congressional and executive branch challenges to certain
aspects of the ACA, as well as recent efforts by the Trump administration to repeal or replace certain aspects of the ACA. Since January 2017, President
Trump has signed two Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise circumvent
some  of  the  requirements  for  health  insurance  mandated  by  the  ACA.  Concurrently,  Congress  has  considered  legislation  that  would  repeal  or  repeal  and
replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under
the ACA have passed. On December 22, 2017, President Trump signed into law new federal tax legislation commonly referred to as the Tax Cuts and Jobs
Act  (the  Tax  Act)  which  includes  a  provision  repealing,  effective  January  1,  2019,  the  tax-based  shared  responsibility  payment  imposed  by  the  ACA  on
certain  individuals  who  fail  to  maintain  qualifying  health  coverage  for  all  or  part  of  a  year  that  is  commonly  referred  to  as  the  “individual  mandate.”  On
January 22, 2018, President Trump signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain ACA-
mandated  fees,  including  the  so-called  “Cadillac”  tax  on  certain  high  cost  employer-sponsored  insurance  plans,  the  annual  fee  imposed  on  certain  health
insurance providers based on market share, and the medical device excise tax on non-exempt medical devices. The Bipartisan Budget Act of 2018, among
other things, amended the ACA, effective January 1, 2019, to close the coverage gap in most Medicare Part D drug plans. In July 2018, CMS published a
final  rule  permitting  further  collections  and  payments  to  and  from  certain  ACA-qualified  health  plans  and  health  insurance  issuers  under  the  ACA  risk
adjustment  program  in  response  to  the  outcome  of  federal  district  court  litigation  regarding  the  method  CMS  uses  to  determine  this  risk  adjustment.  On
December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by
Congress as part of the Tax Act. On December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the District Court ruling that the individual
mandate was unconstitutional and remanded the case to the District Court to determine whether the remaining provisions of the ACA are invalid. While the
Texas U.S. District Court Judge, as well as the Trump administration and CMS, have stated that the ruling will have no immediate effect pending appeal of
the decision, it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the ACA will impact the ACA.

33

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. These changes included aggregate reductions
to Medicare payments to providers of 2% per fiscal year, effective April 1, 2013, which, due to subsequent legislative amendments, will stay in effect through
2027 unless additional Congressional action is taken. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other
things,  reduced  Medicare  payments  to  several  providers,  and  increased  the  statute  of  limitations  period  for  the  government  to  recover  overpayments  to
providers from three to five years. These new laws may result in additional reductions in Medicare and other healthcare funding, which could have a material
adverse effect on customers for our drugs, if approved, and accordingly, our financial operations.

Additionally,  there  has  been  heightened  governmental  scrutiny  recently  over  the  manner  in  which  drug  manufacturers  set  prices  for  their  marketed
products, which has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring
more  transparency  to  product  pricing,  review  the  relationship  between  pricing  and  manufacturer  patient  programs,  and  reform  government  program
reimbursement methodologies for drug products. For example, at the federal level, the Trump administration released a “Blueprint” to lower prescription drug
prices  and  reduce  out-of-pocket  costs  of  drugs  that  contains  additional  proposals  to  increase  manufacturer  competition,  increase  the  negotiating  power  of
certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and reduce the out-of-pocket costs of drug products
paid  by  consumers.  Additionally,  on  January  31,  2019,  HHS  Office  of  Inspector  General  (OIG)  issued  proposed  modifications  to  federal  Anti-Kickback
Statute  safe  harbors  which,  among  other  things,  may  affect  rebates  paid  by  manufactures  to  Medicare  Part  D  plan  sponsors,  Medicaid  managed  care
organizations, and those entities’ pharmacy benefit managers, the purpose of which is to further reduce the cost of drug products to consumers. On October 9,
2019, HHS, OIG and CMS issued two proposed rules that set forth modifications to the Federal Anti-Kickback Statute, Civil Monetary Penalties Law and
Physician Self-Referral Law (or the Stark Law) regulations to promote value-based and coordinated care arrangements. At the state level, legislatures have
increasingly  passed  legislation  and  implemented  regulations  designed  to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient
reimbursement  constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,
designed to encourage importation from other countries and bulk purchasing.

Moreover, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) established the Medicare Part D program to provide a
voluntary prescription drug benefit to Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private
entities that provide coverage of outpatient prescription drugs. Unlike Medicare Part A and B, Part D coverage is not standardized. While all Medicare drug
plans must give at least a standard level of coverage set by Medicare, Part D prescription drug plan sponsors are not required to pay for all covered Part D
drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription
drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category
or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Government
payment for some of the costs of prescription drugs may increase demand for products for which we receive marketing approval. However, any negotiated
prices for our products covered by a Part D prescription drug plan likely will be lower than the prices we might otherwise obtain. Moreover, while the MMA
applies only to drug benefits for Medicare beneficiaries, private third-party payors often follow Medicare coverage policy and payment limitations in setting
their own payment rates.

Corporate Information

34

We  were  incorporated  in  Delaware  in  June  2015.  We  were  spun  out  from  Oculeve,  Inc.,  a  Delaware  corporation  focused  on  the  treatment  of  dry  eye

ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk. Careful consideration should be given to the following risk factors, in addition to the other
information set forth in this Annual Report on Form 10-K and in other documents that we have filed and will file with the SEC, in evaluating our company
and our business. Additional risks and uncertainties not presently known to us or that we currently see as immaterial may also harm our business. If any of
these risks occur, our business, growth prospects, operating results and financial condition could be materially and adversely affected, the trading price of
our common stock could decline and you could lose part or all of your investment.

Risks Related to Our Business

We  are  a  clinical  stage  biopharmaceutical  company  with  limited  operating  history.  We  have  incurred  significant  losses  and  negative  cash  flows  from
operations  since  our  formation,  and  we  anticipate  that  we  will  continue  to  incur  losses  for  the  foreseeable  future.  We  have  no  products  approved  for
commercial sale, which may make it difficult for you to evaluate our current business and predict our future success and viability.

We are a clinical stage biopharmaceutical company with a limited operating history. Our operations to date have been limited to organizing our company,
raising capital and developing our product candidates. Consequently, any predictions you make about our future success or viability may not be as accurate as
they could be if we had a longer operating history. In addition, as a new business, we may encounter unforeseen expenses, difficulties, complications, delays
and other known and unknown factors. We will need to transition from a company with a clinical development focus to a company capable of supporting
commercial  activities.  We  have  not  yet  demonstrated  our  ability  to  successfully  obtain  marketing  approvals,  manufacture  a  commercial-scale  product  or
arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization, and we may not
be successful in such a transition.

We  do  not  have  any  products  approved  for  sale,  we  have  not  generated  any  revenue  and  have  incurred  net  losses  in  each  reporting  period  since  our
company’s formation. We have funded our operations primarily from the sale and issuance of our securities. Our net losses were $45.7 million  and  $16.5
million  for  the  years  ended  December  31,  2019  and  2018,  respectively.  As  of  December  31,  2019,  we  had  an  accumulated  deficit  of  $84.2  million.
Additionally, the net losses we incur may fluctuate significantly from quarter to quarter such that a period-to-period comparison of our results of operations
may not be a good indicator of our future performance. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and
our ability to generate revenue.

35

We expect to continue incurring significant expenses and increasing operating losses for the foreseeable future. We expect that our expenses will increase

substantially if and as we:

•
•
•

initiate additional preclinical, clinical and other studies for our product candidates or expand or modify existing studies or currently planned studies;
change or add additional manufacturers or suppliers, some of which may require additional permits or other governmental approvals;
create additional infrastructure to support our operations as a public company and our product development and planned future commercialization
efforts;
seek marketing approvals and reimbursement for our product candidates;
establish a sales, marketing, and distribution infrastructure to commercialize any products for which we may obtain marketing approval;
seek to identify and develop additional product candidates;
acquire or in-license other product candidates and technologies;

•
•
•
•
• make milestone or other payments in connection with the development or approval of our product candidates;
• maintain, protect, and expand our intellectual property portfolio; and
•
experience any delays or encounter issues with any of the above.

Our prior losses and expected future losses have had and will continue to have an adverse effect on our working capital and our ability to achieve and

maintain profitability.

We  are  highly  dependent  on  the  success  of  our  lead  product  candidate  OC-01  for  the  treatment  of  dry  eye  disease.  If  we  are  unable  to  successfully
complete our clinical development program for OC-01 and obtain the marketing approvals necessary to commercialize OC-01 or experience significant
delays in doing so, or if after obtaining marketing approvals, we fail to commercialize this product candidate, our business will be materially harmed.

We have devoted a significant portion of our financial resources and business efforts to the development of OC-01 for the treatment of dry eye disease
(DED).  Although  we  are  also  developing  OC-01  for  other  indications  and  a  second  product  candidate  OC-02,  we  do  not  anticipate  receiving  marketing
approvals  for  any  product  candidates  other  than  OC-01  in  the  next  several  years.  Our  ability  to  generate  revenues  from  product  sales  will  depend  on  our
obtaining marketing approval for and commercializing OC-01, and we cannot accurately predict when or if OC-01 will be proven to be effective or safe in
humans or whether it will receive marketing approval for DED or a secondary indication. Because we have focused our resources and efforts on developing
OC-01 for DED, we have limited resources and may fail to commit adequate resources to, or delay the pursuit of opportunities for, other indications or other
product  candidates  that  may  have  greater  commercial  potential,  and  our  resource  allocation  decisions  may  cause  us  to  fail  to  capitalize  on  viable  product
candidates and profitable market opportunities. If we fail to successfully develop OC-01 for DED, we may not be able to identify, assess and develop OC-01
for other indications or OC-02 or a second lead product candidate or other product candidates on a timely basis, which could materially affect our business,
financial condition, results of operations and growth prospects.

Our business depends entirely on the successful discovery, development and commercialization of OC-01, OC-02 and other future product candidates. We
currently generate no revenues from sales of any products and may never generate revenue or be profitable.

We have no products approved for commercial sale and do not anticipate generating any revenue until either OC-01 or another product candidate receives
the regulatory and marketing approvals necessary for commercialization. Our ability to generate revenue and achieve profitability depends significantly on
our ability, or any future collaborator’s ability, to achieve a number of objectives, including:

•

•

•

successful and timely completion of preclinical and clinical development of our product candidates, including OC-01, OC-02 and any other future
product candidates;

establishing and maintaining relationships with contract research organizations (CROs) and clinical sites for the clinical development, both in the
United States and internationally, of our product candidates, including OC-01, OC-02 and any other future product candidates;

timely receipt of marketing approvals from applicable regulatory authorities for any product candidates for which we successfully complete clinical
development;

36

• making any required post-marketing approval commitments to applicable regulatory authorities;

•

•

•

•

•

•

•

•

•

•

•

•

establishing  and  maintaining  commercially  viable  supply  and  manufacturing  relationships  with  third  parties  that  can  provide  adequate,  in  both
amount and quality, products and services to support clinical development and meet the market demand for product candidates that we develop, if
approved;

successful  commercial  launch  following  any  marketing  approval,  including  the  development  of  a  commercial  infrastructure,  whether  in-house  or
with one or more collaborators;

a continued acceptable safety profile both prior to and following any marketing approval of our product candidates;

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

identifying, assessing and developing new product candidates;

obtaining,  maintaining  and  expanding  patent  protection,  trade  secret  protection  and  regulatory  exclusivity,  both  in  the  United  States  and
internationally;

protecting our rights in our intellectual property portfolio;

defending against third-party interference or infringement claims, if any;

obtaining  favorable  terms  in  any  collaboration,  licensing  or  other  arrangements  that  may  be  necessary  or  desirable  to  develop,  manufacture  or
commercialize our existing or acquired product candidates;

obtaining coverage and adequate reimbursement by hospitals, government and third-party payors for product candidates that we develop;

addressing any competing therapies and technological and market developments; and

attracting, hiring and retaining qualified personnel.

We may never be successful in achieving our objectives and, even if we do, may never generate revenue that is significant or large enough to achieve
profitability, or comparable to the revenues of existing therapies, including Restasis and Xiidra. If we do achieve profitability, we may not be able to sustain
or  increase  profitability  on  a  quarterly  or  annual  basis.  Our  failure  to  become  and  remain  profitable  would  decrease  the  value  of  our  company  and  could
impair our ability to maintain or further our research and development efforts, raise additional necessary capital, grow our business, retain key employees and
continue our operations.

Our lead product candidate OC-01 is based on an active pharmaceutical ingredient (API) that is already on the market, which exposes us to additional
risks.

The API in OC-01, varenicline (in the form of varenicline tartrate), has been previously approved by the FDA and the EMA as an oral tablet under the
trade name Chantix, an aid to smoking cessation treatment, and is available in more than 80 countries throughout the world. From 2009 to 2016, the FDA
required Chantix to carry a boxed warning advising consumers of potential serious mental health side effects from Chantix. Although the FDA removed this
box  warning  from  Chantix  in  2016  in  response  to  the  EAGLES  study  sponsored  by  Pfizer,  regulatory  authorities  may  identify  other  adverse  side  effects
related to varenicline in the future or may add back the warning. Additionally, we anticipate that manufacturers will begin selling varenicline in generic form
in the future, which could lead to increased use of varenicline by patients and increase the possibility that patients experience adverse side effects related to
varenicline. Any adverse side effects that arise from the use of any form of varenicline, whether Chantix, generic varenicline or our product candidate, or
reporting  thereof  could  prevent  or  inhibit  the  commercialization  of  OC-01  and  seriously  harm  our  business.  Furthermore,  if  manufacturer  demand  for
varenicline  increases  in  the  future,  particularly  as  a  result  of  generic  forms  of  varenicline  becoming  available,  we  may  not  be  able  to  continue  to  obtain
varenicline on commercially reasonable terms, which would seriously harm our business.

OC-01  uses  a  novel  and  unproven  therapeutic  approach  and  mechanism  of  action  to  treat  DED  and  therefore  its  efficacy  and  safety  are  difficult  to
predict, and there is no guarantee that OC-01 or any other product candidates will be approved by the FDA.

37

We are developing OC-01 as a preservative-free, aqueous nasal spray that will stimulate the lacrimal functional unit (LFU) to produce natural tear film.
To our knowledge, OC-01 represents the first pharmacological treatment approach for DED that is aimed at stimulating the LFU. Other than with respect to
data  from  studies  and  trials  of  OC-01  and  OC-02,  there  is  limited  or  no  clinical  evidence  showing  that  natural  tear  film  can  be  produced  through  the
stimulation of the LFU. For instance, even though OC-01 has shown promising results in preclinical studies and prior clinical trials, we may not succeed in
demonstrating  safety  and  efficacy  of  OC-01  in  larger-scale  clinical  trials,  including  ONSET-2,  our  ongoing  Phase  3  clinical  trial,  or  for  other  indications,
including OLYMPIA, our upcoming Phase 2 clinical trial for neurotrophic keratitis (NK).

Advancing OC-01 as a novel product creates significant challenges for us, including:

•

•

•

obtaining marketing approval;

educating medical personnel, including eye care practitioners (ECPs), and patients regarding the potential efficacy and safety benefits, as well as the
challenges, of incorporating our product candidates, if approved, into treatment regimens; and

establishing the sales and marketing capabilities upon obtaining any marketing approvals to gain market acceptance.

We cannot guarantee that OC-01 or any of our other future product candidates will be approved by the FDA. Product candidates in later-stage clinical
trials often fail to demonstrate sufficient safety and efficacy to the satisfaction of the FDA, EMA and other comparable foreign regulatory authorities despite
having successfully progressed through preclinical studies and other clinical trials. In some instances, there can be significant variability in safety and efficacy
results between different clinical trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in size and
type  of  the  patient  populations,  differences  in  and  adherence  to  the  dosing  regimen  and  other  trial  protocols  and  the  rate  of  dropout  among  clinical  trial
participants. For example, although we expect to enroll a subject population with similar eligibility criteria, OC-01 may not demonstrate the same or similar
statistically  significant  results  in  ONSET-2  as  it  demonstrated  in  ONSET-1,  our  Phase  2b  clinical  trial,  MYSTIC,  our  Phase  2  long-term  chronic  efficacy
study, ZEN, our comparative pharmacokinetic “bridge” trial, or our other clinical trials. Additionally, we cannot guarantee that the safety profile of OC-01 in
healthy volunteers and patients with DED will be replicated in trials and studies for other indications, such as NK. Assessments of efficacy can vary widely
for  a  particular  participant,  and  from  participant  to  participant  and  site  to  site  within  a  clinical  trial.  This  subjectivity  can  increase  the  uncertainty  of,  and
adversely impact, our clinical trial outcomes. In addition, participants treated with OC-01 may also be treated with other investigational drugs, prescription
drugs or even over-the-counter treatments following the treatment period of our OC-01 studies, any of which can cause side effects or adverse events that are
unrelated to our product candidate, but which are observed during the long-term safety follow-up for OC-01. The occurrence of such side effects or adverse
events could have a negative impact on OC-01’s safety profile.

Drug  development  is  a  highly  uncertain  undertaking  and  involves  a  substantial  degree  of  risk.  The  outcome  of  preclinical  testing  and  earlier  clinical
trials may not be predictive of the success of later clinical trials. The results of our clinical trials may not satisfy the requirements of the FDA, EMA or
other  comparable  foreign  regulatory  authorities,  and  we  may  incur  additional  costs  or  experience  delays  in  completing,  or  ultimately  be  unable  to
complete, the development and commercialization of such product candidate.

Research  and  development  of  biopharmaceutical  products  is  inherently  risky.  We  cannot  give  any  assurance  that  any  of  our  product  candidates  will
receive  regulatory,  including  marketing,  approval,  which  is  necessary  before  they  can  be  commercialized.  Before  obtaining  regulatory  approvals  for  the
commercial sale of any of our product candidates, we must demonstrate through lengthy, complex and expensive preclinical studies and clinical trials that our
product candidates are both safe and effective for use in each target indication. Product candidates in later stages of clinical trials may fail to show the desired
safety,  efficacy  and  durability  profile  despite  having  progressed  through  preclinical  studies  and  initial  clinical  trials.  A  number  of  companies  in  the
biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or unacceptable safety issues, notwithstanding
promising results in earlier trials. Most product candidates that begin clinical trials are never approved by regulatory authorities for commercialization.

Clinical  testing  is  expensive  and  can  take  many  years  to  complete,  and  its  outcome  is  inherently  uncertain.  Failure  can  occur  at  any  time  during  the
clinical trial process. The results of preclinical and clinical studies of our product candidates may not be predictive of the results of early-stage or later-stage
clinical  trials,  and  results  of  early  clinical  trials  of  our  product  candidates  may  not  be  predictive  of  the  results  of  later-stage  clinical  trials.  The  results  of
clinical trials in one set of subjects may not be predictive of those obtained in another. In some instances, there can be significant variability in safety, efficacy
or durability results between different clinical trials of the same product candidate due to numerous factors, including changes in trial procedures set forth in
protocols, differences in the size and type of the patient populations, changes in and adherence to the dosing regimen and other clinical trial protocols and the
rate of dropout among clinical trial participants.

38

We may also experience issues in implementing our clinical trials that would delay or prevent us from satisfying the applicable requirements of the FDA

and other regulatory authorities, including:

•

•

•

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

our third-party contractors may fail to comply with regulatory requirements or meet their obligations to us in a timely manner, or at all;

other regulators or institutional review boards may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a
prospective trial site; and

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

sites.

We may be unable to design and execute clinical trials that support marketing approval. We cannot be certain that our planned clinical trials or any other
future clinical trials will be successful. For example, use of OC-01 requires the patient to follow a prescribed technique to administer the nasal spray. Failure
to properly administer the nasal spray by the patient or inappropriate technique demonstration by the ECP, may adversely affect the outcome of OC-01 in
demonstrating efficacy in one or more clinical trials. Additionally, any safety concerns observed in any one of our clinical trials in our targeted indications
could limit the prospects for regulatory approval of our product candidates in those and other indications, which could materially affect our business, financial
condition, results of operations and growth prospects.

In addition, even if such clinical trials are successfully completed, we cannot guarantee that the FDA or foreign regulatory authorities will interpret the
results as we do, and more trials could be required before we submit our product candidates for approval. To the extent that the results of the trials are not
satisfactory to the FDA or foreign regulatory authorities for support of a marketing application, we may be required to expend significant resources, which
may not be available to us, to conduct additional trials in support of potential approval of our product candidates. Even if regulatory approval is secured for
any  of  our  product  candidates,  the  terms  of  such  approval  may  limit  the  scope  and  use  of  our  product  candidate,  which  may  also  limit  its  commercial
potential.

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

We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of subjects to
participate in these trials to such trial’s conclusion as required by the FDA, EMA or other comparable foreign regulatory authorities. Patient enrollment is a
significant factor in the timing of clinical trials. Any difficulties we experience relating to enrollment in ONSET-2 could delay regulatory approval for OC-01.

Patient  enrollment  may  be  affected  if  our  competitors  have  ongoing  clinical  trials  for  product  candidates  that  are  under  development  for  the  same
indications as our product candidates, and subjects who would otherwise be eligible for our clinical trials instead enroll in clinical trials of our competitors’
product candidates. Patient enrollment for any of our future clinical trials may be affected by other factors, including:

•

•

•

•

•

•

size and nature of the patient population;

severity of the disease under investigation;

availability and efficacy of approved drugs for the disease under investigation;

participant eligibility criteria for the trial in question as defined in the protocol;

perceived risks and benefits of the product candidate under study;

ECPs’  and  participants’  perceptions  as  to  the  potential  advantages  of  the  product  candidate  being  studied  in  relation  to  other  available  therapies,
including any new products that may be approved for the indications we are investigating;

39

•

•

•

•

•

•

efforts to facilitate timely enrollment in clinical trials;

participant referral practices of ECPs;

the ability to monitor participants adequately during and after treatment;

proximity and availability of clinical trial sites for prospective trial subjects;

continued enrollment of prospective subjects by clinical trial sites; and

the risk that subjects enrolled in clinical trials will drop out of the trials before completion.

Our inability to enroll a sufficient number of subjects for our clinical trials would result in significant delays or may require us to abandon one or more
clinical  trials  altogether.  Enrollment  delays  in  our  clinical  trials  may  result  in  increased  development  costs  for  our  product  candidates  and  jeopardize  our
ability to obtain marketing approval for the sale of our product candidates. Furthermore, even if we are able to enroll a sufficient number of subjects for our
clinical trials, we may have difficulty maintaining enrollment of such subjects in our clinical trials.

Our current or future product candidates may cause or reveal significant adverse events, toxicities or other undesirable side effects which may delay or
prevent  marketing  approval.  In  addition,  if  we  obtain  approval  for  any  of  our  product  candidates,  significant  adverse  events,  toxicities  or  other
undesirable side effects may be identified during post-marketing surveillance, which could result in regulatory action or negatively affect our ability to
market the product.

Adverse events or other undesirable side effects caused by or associated with treatment by our product candidates could cause us or regulatory authorities
to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, EMA or other
comparable foreign regulatory authorities.

During the conduct of clinical trials, subjects report changes in their health, including illnesses, injuries, and discomforts, to their study doctor. Often, it is
not possible to determine whether or not the product candidate being studied caused these conditions. It is possible that as we test our product candidates in
larger, longer and more extensive clinical trials, or as use of these product candidates becomes more widespread if they receive regulatory approval, illnesses,
injuries, discomforts and other adverse events that were not observed in earlier trials, as well as conditions that did not occur or went undetected in previous
trials, will be reported by subjects. Many times, side effects are only detectable after investigational products are tested in large-scale, Phase 3 clinical trials
or, in some cases, after they are made available to subjects on a commercial scale after approval.

The  most  commonly  reported  adverse  events  in  ONSET-1,  ZEN  and  MYSTIC  were  non-ocular  in  nature,  which  were  sneezing  and  coughing.  If
approved, we expect that OC-01 will be used chronically over a prolonged period of time. However, we have no clinical safety data on patients treated with
OC-01 for longer than 84 days and these adverse events are subjective and based on subjects' self-report, which may not accurately reflect the actual number
of adverse events. Our understanding of the relationship between our product candidates and these adverse events may change as we gather more information,
and additional unexpected adverse events may occur. If additional clinical experience indicates that OC-01 or any other product candidate has side effects or
causes serious or life- threatening side effects, participant recruitment for studies and the ability of enrolled subjects to complete studies could be negatively
impacted, and the development of the product candidate may fail or be delayed, which would severely harm our business, growth prospects, operating results
and financial condition.

Additionally, if one or more of our product candidates receives marketing approval, and we or others later identify undesirable side effects or adverse

events caused by such products, a number of potentially significant negative consequences could result, including but not limited to:

•

regulatory authorities may withdraw approvals of such product or require additional warnings on the label;

• we may be required to change the way the product is administered or conduct additional clinical trials or post-approval studies;

• we may be required to create a Risk Evaluation and Mitigation Strategy (REMS) plan, which could include a medication guide outlining the risks of
such side effects for distribution to patients, a communication plan for healthcare providers, including ECPs, and/or other elements to assure safe
use;

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

40

•

our reputation may suffer.

Any  of  these  events  could  prevent  us  from  achieving  or  maintaining  market  acceptance  of  the  particular  product  candidate,  if  approved,  and  could

materially affect our business, financial condition, results of operations, and growth prospects.

Interim, topline and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become
available, and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose preliminary, interim or topline data from our clinical trials. These interim updates are based on a preliminary
analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data
related to the particular study or trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not
have received or had the opportunity to fully and carefully evaluate all data. As a result, the topline results that we report may differ from future results of the
same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Topline data
also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously
published. As a result, topline data should be viewed with caution until the final data are available. In addition, we may report interim analyses of only certain
endpoints rather than all endpoints. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may
materially  change  as  patient  enrollment  continues  and  more  patient  data  become  available.  Adverse  changes  between  interim  data  and  final  data  could
materially affect our business, financial condition, results of operations and growth prospects. Further, additional disclosure of interim data by us or by our
competitors in the future could result in volatility in the price of our common stock. Further, others, including regulatory agencies, may not accept or agree
with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the
value  of  the  particular  program,  the  approvability  or  commercialization  of  the  particular  product  candidate  and  our  company  in  general.  In  addition,  the
information  we  choose  to  publicly  disclose  regarding  a  particular  study  or  clinical  trial  is  typically  selected  from  a  more  extensive  amount  of  available
information. You or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any
information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise
regarding a particular product candidate or our business. If the preliminary or topline data that we report differ from late, final or actual results, or if others,
including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize our product candidates may be
harmed, which could materially affect our business, financial condition, results of operations and growth prospects.

Our success is highly dependent on our ability to attract and retain highly skilled executive officers and employees.

To succeed, we must recruit, retain, manage and motivate qualified executives as we build out the management team, and we face significant competition
for experienced personnel. We are highly dependent on the principal members of our management and need to continue to add executives with operational
and commercialization experience as we plan for commercialization of our product candidates and build out a leadership team that can manage our operations
as a public company. If we do not succeed in attracting and retaining qualified personnel, particularly at the management level, it could adversely affect our
ability to execute our business plan and harm our operating results. In particular, the loss of one or more of our executive officers could be detrimental to us if
we cannot recruit suitable replacements in a timely manner. The competition for qualified personnel in the biotechnology field is intense and as a result, we
may be unable to continue to attract and retain qualified personnel necessary for the future success of our business. We could in the future have difficulty
attracting experienced personnel to our company and may be required to expend significant financial resources in our employee recruitment and retention
efforts.

Many  of  the  other  biotechnology  companies  that  we  compete  against  for  qualified  personnel  have  greater  financial  and  other  resources,  different  risk
profiles and a longer history in the industry than we do. They also may provide more diverse opportunities and better prospects for career advancement. Some
of these characteristics may be more appealing to high-quality candidates than what we have to offer. If we are unable to continue to attract and retain high-
quality  personnel,  the  rate  and  success  at  which  we  can  discover,  develop  and  commercialize  our  product  candidates  will  be  limited  and  the  potential  for
successfully growing our business will be harmed.

If we engage in acquisitions, in-licensing or strategic partnerships, this may increase our capital requirements, dilute our stockholders, cause us to incur
debt or assume contingent liabilities and subject us to other risks.

We  may  engage  in  various  acquisitions  and  strategic  partnerships  in  the  future,  including  licensing  or  acquiring  complementary  products,  intellectual

property rights, technologies or businesses. Any acquisition or strategic partnership may entail numerous risks, including:

41

•

•

•

•

•

•

•

•

increased operating expenses and cash requirements;

the assumption of indebtedness or contingent liabilities;

the issuance of our equity securities which would result in dilution to our stockholders;

assimilation  of  operations,  intellectual  property,  products  and  product  candidates  of  an  acquired  company,  including  difficulties  associated  with
integrating new personnel;

the  diversion  of  our  management’s  attention  from  our  existing  product  candidates  and  initiatives  in  pursuing  such  an  acquisition  or  strategic
partnership;

retention of key employees, the loss of key personnel, and uncertainties in our ability to maintain key business relationships;

risks  and  uncertainties  associated  with  the  other  party  to  such  a  transaction,  including  the  prospects  of  that  party  and  their  existing  products  or
product candidates and regulatory approvals; and

our inability to generate revenue from acquired intellectual property, technology and/or products sufficient to meet our objectives or even to offset
the associated transaction and maintenance costs.

In addition, if we undertake such a transaction, we may incur large one-time expenses and acquire intangible assets that could result in significant future

amortization expense.

We expect to significantly expand our organization, including building sales and marketing capability and creating additional infrastructure to support
our operations as a public company, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

We  expect  to  experience  significant  growth  in  the  number  of  our  employees  and  the  scope  of  our  operations,  particularly  in  the  areas  of  sales  and
marketing and finance and accounting. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational
and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Due to our limited financial resources and our
limited  experience  in  managing  such  anticipated  growth,  we  may  not  be  able  to  effectively  manage  the  expansion  of  our  operations  or  recruit  and  train
additional  qualified  personnel.  The  expansion  of  our  operations  may  lead  to  significant  costs  and  may  divert  or  stretch  our  management  and  business
development resources in a way that we may not anticipate. Any inability to manage growth could delay the execution of our business plans or disrupt our
operations.

Our business and operations would suffer in the event of security breaches, system failures and other disruptions.

Despite the implementation of security measures, our computer systems, as well as those of our contractors and consultants, are vulnerable to damage
from  computer  viruses,  unauthorized  access,  natural  disasters  (including  hurricanes),  terrorism,  war  and  telecommunication  and  electrical  failures.  The
application and data we possess contain critical information, including research and development information, commercial information, personal information
about our employees and consultants, and business and financial information. Protecting this critical information includes risks, including loss of access risk,
inappropriate  disclosure  risk,  inappropriate  modification  risk  and  the  risk  of  being  unable  to  adequately  monitor  our  internal  controls  to  prevent  security
breaches, system failures and other cybersecurity disruptions.

If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our product candidate development
programs. For example, the loss of preclinical study or clinical trial data from completed, ongoing or planned trials could result in delays in our regulatory
approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a
loss of or damage to our data or applications, or inappropriate disclosure of personal, confidential or proprietary information, we could incur liability and the
further development of our product candidates could be delayed.

The  secure  processing,  storage,  maintenance  and  transmission  of  this  information  is  critical  to  our  operations.  Despite  our  security  measures,  our
information  technology  and  infrastructure  may  be  vulnerable  to  attacks  by  hackers  or  internal  bad  actors,  or  breached  due  to  employee  error,  a  technical
vulnerability, malfeasance or other disruptions. Although, to our knowledge, we have not experienced any such material security breach to date, any such
breach could compromise our networks and the

42

information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal
claims or proceedings, liability under laws that protect the privacy of personal information, significant regulatory penalties, and such an event could disrupt
our  operations,  damage  our  reputation,  and  cause  a  loss  of  confidence  in  us  and  our  ability  to  conduct  clinical  trials,  which  could  adversely  affect  our
reputation and delay clinical development of our product candidates.

Furthermore,  the  loss  of  clinical  trial  data  from  completed  or  future  clinical  trials  could  result  in  delays  in  our  regulatory  approval  efforts  and
significantly increase our costs to recover or reproduce the data. Likewise, we rely on other third parties for the manufacture of our product candidates and to
conduct clinical trials, and similar events relating to their computer systems could also have a material adverse effect on our business.

Internal  computer  systems,  or  those  used  by  our  third-party  research  institution  collaborators,  CROs  or  other  contractors  or  consultants,  may  fail  or
suffer  other  breakdowns,  cyber-attacks  or  information  security  breaches  that  could  compromise  the  confidentiality,  integrity,  and  availability  of  such
systems and data, expose us to liability, and affect our reputation.

We are increasingly dependent upon information technology systems, infrastructure, and data to operate our business. We also rely on third party vendors
and their information technology systems. Despite the implementation of security measures, our internal computer systems and those of our CROs and other
contractors and consultants may be vulnerable to damage from computer viruses or unauthorized access, or breached due to operator error, malfeasance or
other  system  disruptions.  As  the  cyber-threat  landscape  evolves,  these  attacks  are  growing  in  frequency,  sophistication  and  intensity,  and  are  becoming
increasingly difficult to detect. These threats can come from a variety of sources, ranging in sophistication from an individual hacker to a state-sponsored
attack. Cyber-threats may be generic, or they may be custom-crafted against our information systems. Over the past few years, cyber-attacks have become
more prevalent, intense, sophisticated and much harder to detect and defend against. Such attacks could include the use of key loggers or other harmful and
virulent malware, including ransomware or other denials of service, and can be deployed through malicious websites, the use of social engineering and/or
other  means.  We  and  our  third  party  vendors  may  not  be  able  to  anticipate  all  types  of  security  threats,  and  we  may  not  be  able  to  implement  preventive
measures effective against all such security threats. The techniques used by cyber criminals change frequently, may not be recognized until launched, and can
originate from a wide variety of sources. Although to our knowledge we and our vendors have not experienced any such material system failure or security
breach to date, if a breakdown, cyber-attack or other information security breach were to occur and cause interruptions in our operations, it could result in a
material disruption of our development programs and our business operations , whether due to a loss of trade secrets or other proprietary information or other
similar disruption and we could incur liability and reputational damage. For example, the loss of clinical trial data from completed, ongoing or future clinical
trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on our
third-party research institution collaborators for research and development of our product candidates and other third parties for the manufacture of our product
candidates and to conduct clinical trials, and similar events relating to their computer systems could also have a material adverse effect on our business.

Cyber-attacks, breaches, interruptions or other data security incidents could result in legal claims or proceedings, liability under federal or state laws that
protect  the  privacy  of  personal  information,  regulatory  penalties,  significant  remediation  costs,  disrupt  key  business  operations  and  divert  attention  of
management and key information technology resources. In the United States, notice of breaches must be made to affected individuals, the U.S. Secretary of
the Department of Health and Human Services, or HHS, and for extensive breaches, notice may need to be made to the media or U.S. state attorneys general.
Such a notice could harm our reputation and our ability to compete. The HHS has the discretion to impose penalties without attempting to resolve violations
through informal means. In addition, U.S. state attorneys general are authorized to bring civil actions seeking either injunctions or damages in response to
violations  that  threaten  the  privacy  of  state  residents.  There  can  be  no  assurance  that  we,  our  collaborators,  CROs,  vendors,  and  any  other  business
counterparties  will  be  successful  in  efforts  to  detect,  prevent,  protect  against  or  fully  recover  systems  or  data  from  all  break-downs,  service  interruptions,
attacks or breaches of systems. In addition, we do not maintain standalone cyber-security insurance and have limited insurance coverage in the event of any
breach or disruption of our or our collaborators’, CROs’, or vendors’ systems, including any unauthorized access or loss of any personal data that we may
collect, store or otherwise process. The costs related to significant security breaches or disruptions could be material and exceed the limits of any insurance
coverage we may have. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or systems, or inappropriate
disclosure  of  confidential  or  proprietary  information,  including  data  related  to  our  personnel,  we  could  incur  liability  and  the  further  development  and
commercialization of our product candidates could be delayed and our business and operations could be adversely affected and/or could result in the loss or
disclosure of critical or sensitive data, which could result in financial, legal, business or reputational harm to us.

Our business is subject to complex and evolving U.S. and foreign laws and regulations, information security policies and contractual obligations relating to
privacy and data protection, including the use, processing, and cross-border transfer of personal information. These laws and regulations are subject to change
and uncertain interpretation, and could result in claims, changes to our business practices, or monetary penalties, and otherwise may harm our business.

43

We  receive,  generate  and  store  significant  and  increasing  volumes  of  sensitive  information  and  business-critical  information,  including  employee  and
personal  data  (including  protected  health  information),  research  and  development  information,  commercial  information,  and  business  and  financial
information.  We  heavily  rely  on  external  security  and  infrastructure  vendors  to  manage  our  information  technology  systems  and  data  centers.  We  face  a
number of risks relative to protecting this critical information, including loss of access risk, inappropriate use or disclosure, inappropriate modification, and
the risk of our being unable to adequately monitor, audit and modify our controls over our critical information. This risk extends to the third-party vendors
and subcontractors we use to manage this sensitive data.

A wide variety of provincial, state, national, and international laws, and regulations apply to the collection, use, retention, protection, disclosure, transfer
and  other  processing  of  personal  data.  These  data  protection  and  privacy-related  laws  and  regulations  are  evolving  and  may  result  in  ever-increasing
regulatory and public scrutiny and escalating levels of enforcement and sanctions. For example, the collection and use of personal data in the European Union
are governed by the European Union General Data Protection Regulation ("GDPR"), which became fully effective on May 25, 2018. The GDPR imposes
stringent  data  protection  requirements,  including,  for  example,  more  robust  disclosures  to  individuals  and  a  strengthened  individual  data  rights  regime,
shortened timelines for data breach notifications, limitations on retention of information, increased requirements pertaining to special categories of data, such
as health data, and additional obligations when we contract with third-party processors in connection with the processing of the personal data. The GDPR also
imposes strict rules on the transfer of personal data out of the European Union to the United States and other third countries and in the context of clinical
trials, we currently rely on patient informed consent as the legal basis for such transfers. In addition, the GDPR provides that European Union member states
may make their own further laws and regulations limiting the processing of personal data, including genetic, biometric or health data. The GDPR provides for
penalties for noncompliance of up to the greater of €20 million or four percent of worldwide annual revenues. The GDPR applies extraterritorially, and we
may be subject to the GDPR because of our data processing activities that involve the personal data of individuals located in the European Union, such as in
connection with any European Union clinical trials. GDPR regulations may impose additional responsibility and liability in relation to the personal data that
we process, and we may be required to put in place additional mechanisms to ensure compliance with the new data protection rules. This may be onerous and
may interrupt or delay our development activities, and adversely affect our business, financial condition, results of operations and growth prospects.

Further, various states, such as California and Massachusetts, have implemented similar privacy laws and regulations that impose restrictive requirements
regulating  the  use  and  disclosure  of  health  information  and  other  personally  identifiable  information.  These  laws  and  regulations  are  not  necessarily
preempted by HIPAA, particularly if a state affords greater protection to individuals than HIPAA. Where state laws are more protective, we have to comply
with  the  stricter  provisions.  In  addition  to  fines  and  penalties  imposed  upon  violators,  some  of  these  state  laws  also  afford  private  rights  of  action  to
individuals who believe their personal information has been misused. For example, California recently enacted legislation, the California Consumer Privacy
Act ("CCPA"), that will, among other things, require covered companies to provide new disclosures to California consumers, and afford such consumers new
abilities to opt-out of certain sales of personal information, that became effective on January 1, 2020. The CCPA was amended several times throughout 2018
and 2019, and it is unclear whether further modifications will be made to this legislation or how it will be interpreted. In addition, the CCPA requires covered
companies  to  provide  new  disclosures  to  individuals  and  consumers  in  California,  and  afford  such  individuals  and  consumers  new  data  protection  rights,
including the ability to opt-out of certain sales of personal information. The GDPR, CCPA and many other laws and regulations relating to privacy and data
protection  are  still  being  tested  in  courts,  and  they  are  subject  to  new  and  differing  interpretations  by  courts  and  regulatory  officials.  Additionally,  the
interplay of federal and state laws may be subject to varying interpretations by courts and government agencies, creating complex compliance issues for us
and data we receive, use and share, potentially exposing us to additional expense, adverse publicity and liability. We are working to comply with the GDPR,
CCPA and other privacy and data protection laws and regulations that apply to us, and we anticipate needing to devote significant additional resources to
complying with these laws and regulations.

It is possible that the GDPR, CCPA or other laws and regulations relating to privacy and data protection may be interpreted and applied in a manner that
is inconsistent from jurisdiction to jurisdiction or inconsistent with our current policies and practices and compliance with such laws and regulations could
require us to change our business practices and compliance procedures in a manner adverse to our business. We cannot guarantee that we are in compliance
with  all  such  applicable  data  protection  laws  and  regulations  and  we  cannot  be  sure  how  these  regulations  will  be  interpreted,  enforced  or  applied  to  our
operations.  Furthermore,  other  jurisdictions  outside  the  European  Union  are  similarly  introducing  or  enhancing  privacy  and  data  security  laws,  rules,  and
regulations, which could increase our compliance costs and the risks associated with noncompliance. It is possible that these laws may be interpreted and
applied in a manner that is inconsistent with our practices and our efforts to comply with the evolving data protection rules may be unsuccessful. We cannot
guarantee that we or our vendors may be in compliance with all applicable international laws and regulations as they are enforced now or as they evolve. For
example,  our  privacy  policies  may  be  insufficient  to  protect  any  personal  information  we  collect  or  may  not  comply  with  applicable  laws.  Our  non-
compliance could result in government-imposed fines or orders requiring that we change our practices, which could adversely affect our business. In addition
to the risks associated with enforcement activities and potential contractual liabilities, our ongoing efforts to comply with evolving laws and regulations at the
federal and state level may be costly and require ongoing modifications to our policies,

44

procedures and systems. In addition, if we are unable to properly protect the privacy and security of protected health information, we could be found to have
breached our contracts.

Our actual or perceived failure to adequately comply with applicable laws and regulations relating to privacy and data protection, or to protect personal
data and other data we process or maintain, could result in regulatory enforcement actions against us, including fines, imprisonment of company officials and
public  censure,  claims  for  damages  by  affected  individuals,  other  lawsuits  or  reputational  and  damage,  all  of  which  could  materially  affect  our  business,
financial condition, results of operations and growth prospects.

Risks Related to Development and Commercialization of Our Product Candidates

Clinical drug development involves a lengthy and expensive process with uncertain timelines and uncertain outcomes, and results of earlier studies and
trials may not be predictive of future results. If clinical trials of our product candidates, particularly OC-01, are prolonged or delayed, we may be unable
to obtain required regulatory approvals, and therefore be unable to commercialize our product candidates on a timely basis or at all.

Before  obtaining  marketing  approval  from  regulatory  authorities  for  the  sale  of  our  product  candidates,  we  must  conduct  extensive  clinical  trials  to
demonstrate the safety and efficacy of the product candidates in humans. To date, we have focused substantially all of our efforts and financial resources on
identifying, acquiring, and developing our product candidates, including conducting preclinical studies and initial clinical trials. Clinical testing is expensive
and can take many years to complete, and we cannot be certain that any clinical trials will be conducted as planned or completed on schedule, if at all. Our
inability  to  successfully  complete  preclinical  and  clinical  development  could  result  in  additional  costs  to  us  and  negatively  impact  our  ability  to  generate
revenue. Our future success is dependent on our ability to successfully develop, obtain regulatory approval for, and then successfully commercialize product
candidates. We currently generate no revenues from sales of any products, and we may never be able to develop or commercialize a marketable product.

Each of our product candidates will require additional clinical development, management of clinical, preclinical and manufacturing activities, regulatory
approval  in  multiple  jurisdictions,  achieving  and  maintaining  commercial-scale  supply,  building  of  a  commercial  organization,  substantial  investment  and
significant marketing efforts before we generate any revenues from product sales. We are not permitted to market or promote any of our product candidates
before we receive regulatory approval from the FDA or comparable foreign regulatory authorities, and we may never receive such regulatory approval for any
of our product candidates. We may experience delays in our ongoing clinical trials and we do not know whether planned clinical trials will begin on time,
need to be redesigned, enroll patients on time or be completed on schedule, if at all.

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

approval or commercialize OC-01 or any other product candidates that we may develop, including:

• we may experience delays in or failure to reach agreement on acceptable terms with prospective CROs and clinical sites, the terms of which can be

subject to extensive negotiation and may vary significantly among different CROs and trial sites;

• we may fail to obtain sufficient enrollment in our clinical trials or participants may fail to complete our clinical trials;

•

clinical trials of our product candidates may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct
additional clinical trials or abandon product development programs;

• we may decide, or regulators or institutional review boards may require us, to suspend or terminate clinical research for various reasons, including

noncompliance with regulatory requirements or a finding that the participants are being exposed to unacceptable health risks;

•

•

•

regulators or institutional review boards may require us to perform additional or unanticipated clinical trials to obtain approval or we may be subject
to additional post-marketing testing requirements to maintain regulatory approval;

regulators may revise the requirements for approving our product candidates, or such requirements may not be as we anticipate;

the cost of clinical trials of our product candidates may be greater than we anticipate, and we may need to delay or suspend one or more trials until
we complete additional financing transactions or otherwise receive adequate funding;

45

•

•

•

the supply or quality of our product candidates or other materials necessary to conduct clinical trials of our product candidates may be insufficient or
inadequate or may be delayed;

our  product  candidates  may  have  undesirable  side  effects  or  other  unexpected  characteristics,  causing  us  or  our  investigators,  regulators  or
institutional review boards to suspend or terminate trials; and

regulatory authorities may suspend or withdraw their approval of a product or impose restrictions on its distribution.

We  do  not  know  whether  any  of  our  preclinical  studies  or  clinical  trials  will  begin  as  planned,  will  need  to  be  restructured  or  will  be  completed  on
schedule, or at all. If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of
our product candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed. In addition, any
delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability
to commence product sales and generate revenues. Significant clinical trial delays could also allow our competitors to bring products to market before we do
or shorten any periods during which we have the exclusive right to commercialize our product candidates and impair our ability to commercialize our product
candidates and may harm our business and results of operations.

We are in the process of validating our manufacturing process and to date, do not have the stability and microbiology data on our product registration
batches necessary for regulatory approval for OC-01.

We are still currently collecting stability and microbiology data on our product registration batches to support NDA approval and to date we do not yet
have data to support an NDA filing. We expect to report top-line results for ONSET-2 by the end of the second quarter 2020 and if results are considered
approvable, we plan to submit an NDA to the FDA in the second half of 2020. However, we manufactured our FDA registration batches of 0.6 mg/ml and 1.2
mg/ml OC-01 nasal spray July and August 2019, and as the FDA requires 12 months stability data to support NDA filing, the data will not be available until
after  August  2020.  Stability  data  is  collected  after  subjecting  our  batches  to  various  conditions,  such  as  refrigeration,  room  temperature,  and  high
temperatures, and it is possible that impurities, particulates, leachables, microbiology, and/or degradation of the active pharmaceutical ingredient, varenicline,
or OC-01 nasal spray could occur or other issues could be detected. If the stability data is not acceptable, we may need to change our manufacturing process,
which could result in a delay of the NDA submission or impact the approval of the product or both, which could materially affect our business, financial
condition, results of operations and growth prospects. The FDA may also impose specific conditions, such as requiring the final product to be shipped and
stored  under  refrigerated  conditions.  Any  additional  requirements  could  result  in  an  increase  in  the  overall  cost  of  the  product  and  complicate  the  supply
chain, which could also materially affect our business, financial condition, results of operations and growth prospects.

OC-01  and  our  other  product  candidates  have  never  been  manufactured  on  a  commercial  scale,  and  there  are  risks  associated  with  scaling  up
manufacturing to commercial scale.

To date, our third-party manufacturer has only manufactured our OC-01 nasal spray in limited quantities in batch sizes appropriate for our clinical trials
and registration batches to support the NDA submission, for which batch sizes are a fraction of the size we expect will be necessary for commercialization.
The manufacturing processes for commercial scale are still being developed and have not been tested and the process validation requirement has not yet been
satisfied. Although we plan to manufacture commercial scale batches of OC-01 nasal spray on the same manufacturing line as the registration batches, with
the  same  equipment,  only  at  higher  scale,  there  are  risks  associated  with  scaling  up  manufacturing  to  commercial  volumes  including,  among  others,  cost
overruns, technical or other problems with process scale-up, process reproducibility, stability issues, lot consistency and timely availability of raw materials.
There is no assurance that our manufacturer will be successful in establishing a larger-scale commercial manufacturing process for OC-01 that achieves our
objectives for manufacturing capacity and cost of goods, in a timely manner or at all. In addition, there is no assurance that our manufacturers will be able to
manufacture OC-01 to specifications acceptable to the FDA or other regulatory authorities, to produce it in sufficient quantities to meet the requirements for
the potential launch of OC-01 or to meet potential future demand. If our manufacturers are unable to produce sufficient quantities of approved products for
commercialization, either on a timely basis or at all, and in a cost-effective manner, our commercialization efforts would be impaired, including impacting the
launch of OC-01 or inventory levels, which could materially affect our business, financial condition, results of operations and growth prospects.

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to sell and market our product candidates on
acceptable terms, we may be unable to successfully commercialize our product candidates that obtain regulatory approval.

We currently do not have and have never had a marketing or sales team. In order to commercialize any product candidates, if approved, we must build

marketing, sales, distribution, managerial and other non-technical capabilities or make arrangements

46

with third parties to perform these services for each of the territories in which we may have approval to sell and market our product candidates. We may not
be successful in accomplishing these required tasks.

Establishing  an  internal  sales  and  marketing  team  with  technical  expertise  and  supporting  distribution  capabilities  to  commercialize  our  product
candidates  will  be  expensive  and  time-consuming,  and  will  require  significant  attention  of  our  executive  officers  to  manage.  Any  failure  or  delay  in  the
development of our internal sales, marketing and distribution capabilities could adversely impact the commercialization of any of our product candidates that
we obtain approval to market, if we do not have arrangements in place with third parties to provide such services on our behalf. Alternatively, if we choose to
collaborate, either globally or on a territory-by-territory basis, with third parties that have direct sales forces and established distribution systems, either to
augment our own sales force and distribution systems or in lieu of our own sales force and distribution systems, we will be required to negotiate and enter into
arrangements  with  such  third  parties  relating  to  the  proposed  collaboration.  If  we  are  unable  to  enter  into  such  arrangements  when  needed,  on  acceptable
terms,  or  at  all,  we  may  not  be  able  to  successfully  commercialize  any  of  our  product  candidates  that  receive  regulatory  approval  or  any  such
commercialization may experience delays or limitations. If we are unable to successfully commercialize our approved product candidates, either on our own
or through collaborations with one or more third parties, our future product revenue will suffer and we may incur significant additional losses.

Furthermore, we believe that approximately 26% of prescribing ECPs account for 80% of the volume of DED prescription treatments. If we are unable to
obtain  access  to  these  ECPs  or  persuade  adequate  numbers  of  ECPs  to  prescribe  our  products,  if  and  when  approved,  our  efforts  to  commercialize  such
products will be severely inhibited, which would have a material adverse effect on our business.

Even if OC-01 or any other product candidate receives marketing approval, they may fail to achieve market acceptance by ECPs and patients, or adequate
formulary coverage, pricing or reimbursement by third-party payors and others in the medical community, and the market opportunity for these products
may be smaller than we estimate.

If OC-01 or any other product candidate that we develop receives marketing approval, it may nonetheless fail to gain sufficient market acceptance by
ECPs, patients, third-party payors and others in the medical community. Current treatments that are commonly used in the United States for DED include
over-the-counter  eye  drops,  often  referred  to  as  “artificial  tears”,  Restasis,  Xiidra  and  off-label  use  of  corticosteroids.  In  particular,  existing  prescription
therapies, notably Restasis and Xiidra, are marketed by much larger biopharmaceutical companies with established brand recognition. As a result, even if OC-
01 demonstrates promising or superior clinical results, including the treatment of both signs and symptoms of DED, it is possible that ECPs may continue to
rely on these treatments rather than OC-01 or any other product candidate, if and when approved for marketing by the FDA. In addition, if generic versions of
any products that compete with any of our product candidates are approved for marketing by the FDA, they would likely be offered at a substantially lower
price than we expect to offer for our product candidates, if approved. As a result, ECPs, patients and third-party payors may choose to rely on such products
rather than our product candidates.

If OC-01 or any other product candidate does not achieve an adequate level of acceptance, formulary coverage, pricing or reimbursement we may not
generate significant product revenues and we may not become profitable. The degree of market acceptance of OC-01 or any other product candidate that we
develop, if approved for commercial sale, will depend on a number of factors, including:

•

•

•

•

•

•

•

the efficacy and potential advantages of our product candidates compared to alternative treatments, including the existing standard of care;

our ability to offer our products for sale at competitive prices, particularly in light of the lower cost of alternative treatments;

the clinical indications for which the product is approved;

the convenience and ease of administration compared to alternative treatments;

the willingness of the target patient population to try new therapies and of ECPs to prescribe these therapies;

the strength of our marketing and distribution support;

publicity concerning our products or competing products and treatments;

47

•

•

•

•

•

the timing of market introduction of competitive products;

the potential for our competitors to limit our access to the market through anti-competitive contracts or other arrangements;

the availability of third-party formulary coverage and adequate reimbursement, particularly by Medicare in light of the prevalence of DED in persons
over age 55;

the prevalence and severity of any side effects; and

any restrictions on the use of our products together with other medications.

Our assessment of the potential market opportunity for OC-01 and other product candidates is based on industry and market data that we obtained from
industry publications and research, surveys and studies conducted by third parties, some of which we commissioned. Industry publications and third- party
research, surveys and studies generally indicate that their information has been obtained from sources believed to be reliable, although they do not guarantee
the accuracy or completeness of such information. While we believe these industry publications and third-party research, surveys and studies are reliable, we
have not independently verified such data. Similarly, although the studies we have commissioned are based on information that we believe to be complete and
reliable,  we  cannot  guarantee  that  such  information  is  accurate  or  complete.  The  potential  market  opportunity  for  the  treatment  of  DED  in  particular  is
difficult to precisely estimate. Our estimates of the potential market opportunities for our product candidates include several key assumptions based on our
industry knowledge, industry publications, third-party research and other surveys, which may be based on a small sample size and fail to accurately reflect
market opportunities. Further, we have commissioned a number of market studies that are specific to us and to our product candidates and used the results of
these studies to help assess our market opportunity. While we believe that our internal assumptions and the bases of our commissioned studies are reasonable,
no independent source has verified such assumptions or bases. If any of our assumptions or estimates, or these publications, research, surveys or studies prove
to be inaccurate, then the actual market for OC-01 or any of our other product candidates may be smaller than we expect, and as a result our product revenue
may be limited and it may be more difficult for us to achieve or maintain profitability.

Even  if  we  obtain  regulatory  approval  for  any  of  our  product  candidates,  we  may  be  subject  to  ongoing  regulatory  obligations  or  post-marketing
commitments as specified by the FDA or other regulatory authorities, which may result in additional costs associated with those commitments.

If we obtain regulatory approval for OC-01 or any other product candidate, such approved products will be subject to continual regulatory review by the
FDA  and/or  non-U.S.  regulatory  authorities.  Additionally,  any  product  candidates,  if  approved,  will  be  subject  to  extensive  and  ongoing  regulatory
requirements,  including  labeling  and  other  restrictions  and  market  withdrawal  and  we  may  be  subject  to  penalties  if  we  fail  to  comply  with  regulatory
requirements or experience unanticipated problems with such products.

If FDA or a comparable foreign regulatory authority approves any of our product candidates, including OC-01, the manufacturing processes, labeling,
packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing
regulatory  requirements.  These  requirements  include  submissions  of  safety  and  other  post-marketing  information  and  reports,  registration,  as  well  as
continued compliance with current Good Manufacturing Practices (cGMP), as well as Good Clinical Practice (GCP) for any clinical trials that we conduct
post-approval, all of which may result in significant expense and limit our ability to successfully commercialize such products. In addition, any regulatory
approvals that we receive for our product candidates may also be subject to limitations on the approved indications or conditions of use for which the product
may be marketed or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials, and surveillance to monitor the safety
and efficacy of the product.

Later  discovery  of  previously  unknown  problems  with  our  product  candidates,  including  adverse  events  of  unanticipated  severity  or  frequency,  or

problems with our third-party manufacturers’ processes, or failure to comply with regulatory requirements, may result in, among other things:

•

•

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

fines, warning letters or holds on clinical trials;

48

•

•

•

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

product seizure or detention, or refusal to permit the import or export of products; and

injunctions or the imposition of civil or criminal penalties.

Our  ongoing  regulatory  requirements  may  also  change  from  time  to  time,  potentially  harming  or  making  costlier  our  commercialization  efforts.  We
cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United
States or other countries. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are
not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability,
which would adversely affect our business.

We face significant competition, and if our competitors develop and market technologies or products more rapidly than we do or that are more effective,
safer or less expensive than the product candidates we develop, our commercial opportunities will be negatively impacted. Our product candidates will, if
approved, also compete with existing branded, generic and off-label products.

The development and commercialization of new drug products is highly competitive. We face competition with respect to OC-01 for the treatment of
DED, and will face competition with respect to OC-01 for other indications and any other product candidates that we may seek to develop or commercialize
in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. Potential competitors also
include  academic  institutions,  government  agencies  and  other  public  and  private  research  organizations  that  conduct  research,  seek  patent  protection  and
establish collaborative arrangements for research, development, manufacturing and commercialization.

The DED market is already served by a variety of competing products. Many of these existing products have achieved widespread acceptance among
ECPs, patients and payors. In addition, certain of these products are available, or may become available, on a generic basis, and our product candidates may
not  demonstrate  sufficient  additional  clinical  benefits  to  ECPs,  patients  or  payors  to  justify  a  higher  price  compared  to  generic  products.  In  many  cases,
insurers or other third-party payors, particularly Medicare, seek to encourage the use of generic products.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have
fewer  or  less  severe  side  effects,  are  more  convenient  or  are  less  expensive  than  our  products.  Our  competitors  also  may  obtain  FDA  or  other  regulatory
approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position
before we are able to enter the market.

In addition, our ability to compete may be affected in many cases by insurers or other third-party payors, particularly Medicare, seeking to encourage the
use of generic products. Generic products are currently being used for certain of the indications that we are pursuing, and additional products are expected to
become available on a generic basis over the coming years.

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

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

Our business exposes us to significant product liability risks inherent in the development, testing, manufacturing and marketing of therapeutic treatments.
Product liability claims could delay or prevent completion of our development programs. If our product candidates are approved for marketing, such claims
could still result in an FDA, EMA or other regulatory authority investigation of the safety and effectiveness of such products, our manufacturing processes
and  facilities  or  our  marketing  programs.  These  investigations  could  potentially  lead  to  a  recall  of  our  products  or  more  serious  enforcement  action,
limitations on the approved indications for which they may be used or suspension or withdrawal of approvals. Regardless of the merits or

49

eventual outcome, liability claims may also result in injury to our reputation, withdrawal of clinical trial participants, costs to defend the related litigation, a
diversion of management’s time and our resources, initiation of investigations by regulators, 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.  We  currently  have
product liability insurance that we believe is appropriate for our stage of development and may need to obtain higher levels prior to marketing any of our
product  candidates,  if  approved.  Any  insurance  we  have  or  may  obtain  may  not  provide  sufficient  coverage  against  potential  liabilities  and,  if  judgments
exceed our insurance coverage, could adversely affect our results of operations and business and cause our stock price to decline. Furthermore, clinical trial
and product liability insurance is becoming increasingly expensive. As a result, we may be unable to maintain or obtain insurance coverage at a reasonable
cost or in sufficient amounts to protect us against losses, including those caused by product liability claims.

A variety of risks associated with marketing our product candidates internationally could materially adversely affect our business.

We  plan  to  seek  regulatory  approval  of  our  product  candidates  outside  of  the  United  States  and,  accordingly,  we  expect  that  we  will  be  subject  to

additional risks related to operating in foreign countries if we obtain the necessary approvals, including:

•

•

•

•

•

•

•

differing regulatory requirements and reimbursement regimes in foreign countries;

unexpected changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements;

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

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

foreign taxes, including withholding of payroll taxes;

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

difficulties staffing and managing foreign operations;

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

•

•

•

•

potential liability under the U.S. Foreign Corrupt Practices Act (FCPA) or comparable foreign regulations;

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

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

business interruptions resulting from geo-political actions, including war and terrorism.

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

Following the United Kingdom’s departure from the EU on January 31, 2020, commonly referred to as "Brexit", there is a “transition period” ending
December 31, 2020 during which the United Kingdom will essentially be treated as a Member State of the EU and the regulatory regime will remain the same
across  the  United  Kingdom  and  the  EU.  The  Withdrawal  Agreement  allows  for  this  “transition  period”  to  be  extended  by  one  or  two  years,  but  the  U.K.
government is currently legislating to require the transition period to end on December 31, 2020 without the possibility to extend further. In that scenario, the
trading relationship between the United Kingdom and the EU will be governed by whatever agreement the two parties can reach in the course of 2020. On
that short timetable the United Kingdom and EU are likely to focus on ensuring tariff-free trade but it is unclear whether there would be any formal regulatory
alignment between United Kingdom and EU rules after January 1, 2021. In the unlikely event that the United Kingdom leaves the EU without an agreement,
so called “hard Brexit,” the United Kingdom will be completely separated from a regulatory perspective from the EU immediately upon the exit date.

Since the regulatory framework for pharmaceutical products in the United Kingdom relating to quality, safety and efficacy of pharmaceutical products,
clinical trials, marketing authorization, commercial sales and distribution of pharmaceutical products is derived from EU directives and regulations, Brexit
will materially impact the future regulatory regime which applies to products

50

and  the  approval  of  product  candidates  in  the  United  Kingdom.  In  the  first  instance,  a  separate  United  Kingdom  authorization  from  any  centralized
authorization  for  the  EU  would  need  to  be  applied  for  in  advance  of  a  hard  Brexit  or  before  the  end  of  any  agreed  transition  period.  In  the  immediately
foreseeable future, the process is likely to remain very similar to that applicable in the EU, albeit that the processes for applications will be separate. Longer
term, the United Kingdom is likely to develop its own legislation that diverges from that in the EU.

Risks Related to Intellectual Property

If  we  are  unable  to  obtain  and  maintain  patent  protection  for  our  technology  and  products,  or  if  the  scope  of  the  patent  protection  obtained  is  not
sufficiently broad, we may not be able to compete effectively in our markets.

We rely upon a combination of patents, trademarks, trade secret protection, and confidentiality agreements to protect the intellectual property related to
our development programs and product candidates. Our success depends in part on our ability to obtain and maintain patent protection in the United States
and other countries with respect to OC-01, OC-02, and any future product candidates. We seek to protect our proprietary position by filing patent applications
in  the  United  States  and  abroad  related  to  our  development  programs  and  product  candidates.  The  patent  prosecution  process  is  expensive  and  time-
consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner.

The  patents  and  patent  applications  that  we  own  may  fail  to  result  in  issued  patents  with  claims  that  protect  OC-01,  OC-02  or  any  future  product
candidate in the United States or in other foreign countries. There is no assurance that all of the potentially relevant prior art relating to our patents and patent
applications has been found, which can prevent a patent from issuing from a pending patent application, or be used to invalidate a patent. Even if patents do
successfully issue and even if such patents cover OC-01, OC-02 or any future product candidate, third parties may challenge their validity, enforceability or
scope, which may result in such patents being narrowed, invalidated or held unenforceable. Any successful opposition to these patents or any other patents
owned by or licensed to us could deprive us of rights necessary for the successful commercialization of any product candidates that we may develop. Further,
if  we  encounter  delays  in  regulatory  approvals,  the  period  of  time  during  which  we  could  market  a  product  candidate  under  patent  protection  could  be
reduced.

The  patent  application  process  is  subject  to  numerous  risks  and  uncertainties,  and  there  can  be  no  assurance  that  we  or  any  of  our  potential  future

collaborators will be successful in protecting our product candidates by obtaining and defending patents. These risks and uncertainties include the following:

•

•

•

•

•

•

the USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other
provisions during the patent process, the noncompliance with which can result in abandonment or lapse of a patent or patent application, and partial
or complete loss of patent rights in the relevant jurisdiction;

patent applications may not result in any patents being issued;

patents may be challenged, invalidated, modified, revoked, circumvented, found to be unenforceable or otherwise may not provide any competitive
advantage;

our competitors, many of whom have substantially greater resources than we do and many of whom have made significant investments in competing
technologies, may seek or may have already obtained patents that will limit, interfere with or block our ability to make, use and sell our product
candidates;

there may be significant pressure on the U.S. government and international governmental bodies to limit the scope of patent protection both inside
and outside the United States for disease treatments that prove successful, as a matter of public policy regarding worldwide health concerns; and

countries  other  than  the  United  States  may  have  patent  laws  less  favorable  to  patentees  than  those  upheld  by  U.S.  courts,  allowing  foreign
competitors a better opportunity to create, develop and market competing products.

The patent prosecution process is also expensive and time consuming, and we may not be able to file and prosecute all necessary or desirable patent
applications at a reasonable cost or in a timely manner or in all jurisdictions where protection may be commercially advantageous. It is also possible that we
will  fail  to  identify  patentable  aspects  of  our  research  and  development  output  before  it  is  too  late  to  obtain  patent  protection.  Moreover,  if  we  choose  to
license  certain  patent  rights  in  the  future  from  third  parties,  we  may  not  have  the  right  to  control  the  preparation,  filing  and  prosecution  of  such  patent
applications, or to

51

maintain the patents, directed to technology that we license from those third parties. We may also require the cooperation of our future licensor, if any, in
order to enforce the licensed patent rights, and such cooperation may not be provided. Therefore, any licensed patents and applications may not be prosecuted
and enforced in a manner consistent with the best interests of our business. We cannot be certain that patent prosecution and maintenance activities by any of
our future licensors have been or will be conducted in compliance with applicable laws and regulations, which may affect the validity and enforceability of
such patents or any patents that may issue from such applications. If they fail to do so, this could cause us to lose rights in any applicable intellectual property
that we in-license, and as a result our ability to develop and commercialize products or product candidates may be adversely affected and we may be unable to
prevent competitors from making, using and selling competing products.

If the patent applications we hold or may in-license in the future with respect to our development programs and product candidates fail to issue, if their
breadth or strength of protection is threatened, or if they fail to provide meaningful exclusivity for OC-01, OC-02 or any future product candidate, it could
dissuade  other  companies  from  collaborating  with  us  to  develop  product  candidates,  and  threaten  our  ability  to  commercialize  OC-01,  OC-02  or  future
product candidates. Any such outcome could have a materially adverse effect on our business.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has
been and will continue to be the subject of litigation and new legislation. In addition, the laws of foreign countries may not protect our rights to the same
extent as the laws of the United States. For example, many countries restrict the patentability of methods of treatment of the human body. Publications in
scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until
18 months after filing, or in some cases not at all. Therefore, we cannot know with certainty whether we were the first to make the inventions claimed in our
own patents or pending patent applications, or that we were the first to file for patent protection of such inventions. As a result of these and other factors, the
issuance, scope, validity, enforceability, and commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not
result  in  patents  being  issued  which  protect  our  technology  or  products,  in  whole  or  in  part,  or  which  effectively  prevent  others  from  commercializing
competitive technologies and products. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may
diminish the value of our patents or narrow the scope of our patent protection.

Moreover,  we  may  be  subject  to  a  third-party  pre-issuance  submission  of  prior  art  to  the  USPTO  or  become  involved  in  opposition,  derivation,
reexamination,  inter  partes  review,  post-grant  review  or  interference  proceedings  challenging  our  patent  rights  or  the  patent  rights  of  others.  The  costs  of
defending our patents or enforcing our proprietary rights in post-issuance administrative proceedings and litigation can be substantial and the outcome can be
uncertain. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third
parties  to  commercialize  our  technology  or  products  and  compete  directly  with  us,  without  payment  to  us,  or  result  in  our  inability  to  manufacture  or
commercialize products without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent
applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.

The  issuance  of  a  patent  is  not  conclusive  as  to  its  inventorship,  scope,  validity  or  enforceability,  and  patents  in  which  we  have  an  interest  may  be
challenged  in  the  courts  or  patent  offices  in  the  United  States  and  abroad.  Such  challenges  may  result  in  loss  of  exclusivity  or  in  patent  claims  being
narrowed,  invalidated  or  held  unenforceable,  in  whole  or  in  part,  which  could  limit  our  ability  to  stop  others  from  using  or  commercializing  similar  or
identical technology and products, or limit the duration of the patent protection of our technology and products. Generally, issued patents are granted a term of
20 years from the earliest claimed non-provisional filing date. In certain instances, patent term can be adjusted to recapture a portion of delay incurred by the
USPTO in examining the patent application (patent term adjustment). The scope of patent protection may also be limited.

Without patent protection for our current or future product candidates, we may be open to competition from generic versions of such products. Given the
amount  of  time  required  for  the  development,  testing,  and  regulatory  review  of  new  product  candidates,  patents  protecting  such  candidates  might  expire
before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from
commercializing products similar or identical to ours.

Depending upon the timing, duration and specifics of FDA marketing approval of OC-02 and future product candidates, one or more of our U.S. patents
may  be  eligible  for  limited  patent  term  restoration  under  the  Drug  Price  Competition  and  Patent  Term  Restoration  Act  of  1984,  referred  to  as  the  Hatch-
Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years beyond the normal expiration of the patent as
compensation  for  patent  term  lost  during  drug  development  and  the  FDA  regulatory  review  process,  which  is  limited  to  the  approved  indication  (or  any
additional  indications  approved  during  the  period  of  extension).  This  extension  is  based  on  the  first  approved  use  of  a  product  and  is  limited  to  only  one
patent  that  covers  the  approved  product,  the  approved  use  of  the  product,  or  a  method  of  manufacturing  the  product.  However,  the  applicable  authorities,
including the FDA and the USPTO in the United States, and any equivalent regulatory authority in other

52

countries, may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions to our patents, or may grant more
limited extensions than we request. We may not be granted an extension because of, for example, failing to apply within applicable deadlines, failing to apply
prior  to  expiration  of  relevant  patents  or  otherwise  failing  to  satisfy  applicable  requirements.  Moreover,  the  applicable  time-period  or  the  scope  of  patent
protection afforded could be less than we request. If we are unable to extend the expiration date of our existing patents or obtain new patents with longer
expiry dates, our competitors may be able to take advantage of our investment in development and clinical trials by referencing our clinical and preclinical
data to obtain approval of competing products following our patent expiration and launch their product earlier than might otherwise be the case.

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

Periodic maintenance fees on any issued patent are due to be paid to the USPTO and other foreign patent agencies in several stages over the lifetime of
the  patent.  The  USPTO  and  various  foreign  national  or  international  patent  agencies  require  compliance  with  a  number  of  procedural,  documentary,  fee
payment, and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee
or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or
patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Noncompliance events that could result in abandonment or
lapse of patent rights include, but are not limited to, failure to timely file national and regional stage patent applications based on our international patent
application,  failure  to  respond  to  official  actions  within  prescribed  time  limits,  non-payment  of  fees,  and  failure  to  properly  legalize  and  submit  formal
documents. If we or any of our licensors fail to maintain the patents and patent applications covering OC-01, OC-02 or any future product candidate, our
competitors may be able to enter the market, which would have an adverse effect on our business.

We  may  not  identify  relevant  third-party  patents  or  may  incorrectly  interpret  the  relevance,  scope  or  expiration  of  a  third-party  patent,  which  might
adversely affect our ability to develop and market our products.

We  cannot  guarantee  that  any  of  our  patent  searches  or  analyses,  including  the  identification  of  relevant  patents,  the  scope  of  patent  claims  or  the
expiration  of  relevant  patents,  are  complete  or  thorough,  nor  can  we  be  certain  that  we  have  identified  each  and  every  third-party  patent  and  pending
application  in  the  United  States  and  abroad  that  is  relevant  to  or  necessary  for  the  commercialization  of  our  current  and  future  product  candidates  in  any
jurisdiction.

The  scope  of  a  patent  claim  is  determined  by  an  interpretation  of  the  law,  the  written  disclosure  in  a  patent  and  the  patent’s  prosecution  history.  Our
interpretation  of  the  relevance  or  the  scope  of  a  patent  or  a  pending  application  may  be  incorrect,  which  may  negatively  impact  our  ability  to  market  our
products. We may incorrectly determine that our products are not covered by a third-party patent or may incorrectly predict whether a third party’s pending
application will issue with claims of relevant scope. Our determination of the expiration date of any patent in the United States or abroad that we consider
relevant may be incorrect, and our failure to identify and correctly interpret relevant patents may negatively impact our ability to develop and market our
products.

Third-party  claims  or  litigation  alleging  infringement  of  patents  or  other  proprietary  rights,  or  seeking  to  invalidate  our  patents  or  other  proprietary
rights, may delay or prevent the development and commercialization of OC-01, OC-02, and any future product candidate.

Our commercial success depends in part on our avoiding infringement and other violations of the patents and proprietary rights of third parties. There is a
substantial amount of 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, derivation, and administrative law proceedings, inter partes review, and post-
grant review before the USPTO, as well as oppositions and similar processes in foreign jurisdictions. 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  collaborators  are  developing  product  candidates.  As  the
biotechnology and pharmaceutical industries expand and more patents are issued, and as we gain greater visibility and market exposure as a public company,
the risk increases that our product candidates or other business activities may be subject to claims of infringement of the patent and other proprietary rights of
third parties. Third parties may assert that we are infringing their patents or employing their proprietary technology without authorization.

Also, 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  current  and  future  product  candidates.  Because  patent  applications  can  take  many  years  to  issue,  there  may  be
currently pending patent applications which may later result in issued patents that our current or future product candidates may infringe.

53

We are aware of three issued U.S. patents owned by Pfizer (U.S. Pat. No.: 7,265,119 (the ‘119), 6,890,927 (the ‘927) and 6,410,550 (the ‘550)) that Pfizer
has listed in the Orange Book as covering its varenicline tartrate product, which is marketed as Chantix as an aid to smoking cessation treatment. Certain
claims of these three patents are directed toward the compound varenicline tartrate and related salts thereof, and therefore may be relevant to our candidate
OC-01. Of the three issued patents, we anticipate that only the ‘119 and the ‘927 will be in force at the time that we could expect to receive FDA approval of
OC-01 and on October 18, 2019, we entered into a non-exclusive patent license for these patents. The ‘550 is listed in the Orange Book as expiring May 10,
2020, with pediatric exclusivity expiring November 10, 2020, and based on our current development plans, we anticipate that both the patent and pediatric
exclusivity associated with the ‘550 will no longer be in force at the time of our expected FDA approval. However, even with the aforementioned license, we
cannot provide assurances that third parties won’t allege infringement, which could delay or prevent the development and commercialization of OC-01 or
other product candidates.

In addition, third parties may obtain patent rights in the future and claim that use of our technologies infringes upon their rights. If any third-party patents
were  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,  methods  of  treating  certain  diseases  or  conditions  that  we  are  pursuing  with  our  product  candidates,  our  formulations  including
combination therapies, 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. Such a license may not be available on commercially reasonable terms
or  at  all.  In  addition,  we  may  be  subject  to  claims  that  we  are  infringing  other  intellectual  property  rights,  such  as  trademarks  or  copyrights,  or
misappropriating  the  trade  secrets  of  others,  and  to  the  extent  that  our  employees,  consultants  or  contractors  use  intellectual  property  or  proprietary
information owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

Parties  making  claims  against  us  may  obtain  injunctive  or  other  equitable  relief,  which  could  effectively  block  our  ability  to  further  develop  and
commercialize  one  or  more  of  our  current  and  future  product  candidates.  Defense  of  these  claims,  regardless  of  their  merit,  would  involve  substantial
litigation  expense  and  would  be  a  substantial  diversion  of  employee  resources  from  our  business.  In  the  event  of  a  successful  infringement  or  other
intellectual property claim against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain
one or more licenses from third parties, pay royalties or redesign our affected products, which may be impossible or require substantial time and monetary
expenditure.  We  cannot  predict  whether  any  such  license  would  be  available  at  all  or  whether  it  would  be  available  on  commercially  reasonable  terms.
Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our
product candidates, and we have done so from time to time. We may fail to obtain any of 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 which might be enforced against our product candidates, resulting in either an injunction
prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties or other forms of compensation to third parties.

During  the  course  of  any  intellectual  property  litigation,  there  could  be  public  announcements  of  the  initiation  of  the  litigation  as  well  as  results  of
hearings, rulings on motions, and other interim proceedings in the litigation. If securities analysts or investors regard these announcements as negative, the
perceived value of our existing products, programs or intellectual property could be diminished. Accordingly, the market price of shares of our common stock
may decline. Such announcements could also harm our reputation or the market for our future products, which could have a material adverse effect on our
business.

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

Competitors may infringe or otherwise violate our patents, the patents of our licensors or our other intellectual property rights. To counter infringement or
unauthorized use or misappropriations, we may be required to file legal claims, which can be expensive and time-consuming. In addition, in an infringement
proceeding, a court may decide that one or more patent of ours or any of our current or future licensors is not valid or is unenforceable, or may refuse to stop
the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation
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. The initiation of a claim against a third party may also cause the third party to bring counter claims against us such as claims asserting that our
patents  are  invalid  or  unenforceable.  In  patent  litigation  in  the  United  States,  defendant  counterclaims  alleging  invalidity  or  unenforceability  are
commonplace.  Grounds  for  a  validity  challenge  could  be  an  alleged  failure  to  meet  any  of  several  statutory  requirements,  including  lack  of  novelty,
obviousness, non-enablement or lack of statutory subject matter. Grounds for an unenforceability assertion could be an allegation that someone connected
with prosecution of the patent withheld relevant material information from the USPTO, or made a materially misleading statement, during prosecution. Third
parties may also raise similar validity claims before the USPTO in post-grant proceedings such as ex

54

parte reexaminations, inter partes review, or post-grant review, or oppositions or similar proceedings outside the United States, in parallel with litigation or
even outside the context of litigation. The outcome following legal assertions of invalidity and unenforceability is unpredictable. We cannot be certain that
there  is  no  invalidating  prior  art,  of  which  we  and  the  patent  examiner  were  unaware  during  prosecution.  For  any  patents  and  patent  applications  that  we
license  from  third  parties,  we  may  have  limited  or  no  right  to  participate  in  the  defense  of  such  licensed  patents  against  challenge  by  a  third  party.  If  a
defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our
current or future product candidates. Such a loss of patent protection could harm our business.

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 Our business could be harmed if in litigation the prevailing party does not offer us a license on
commercially reasonable terms. Any litigation or other proceedings to enforce our intellectual property rights may fail, and even if successful, may result in
substantial costs and distract our management and other employees.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our
confidential  information  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  an
adverse effect on the price of our common shares.

Because of the expense and uncertainty of litigation, we may not be in a position to enforce our intellectual property rights against third parties.

Because of the expense and uncertainty of litigation, we may conclude that even if a third party is infringing our in-licensed patents, any patents that may
be issued as a result of our future patent applications, or other intellectual property rights, the risk-adjusted cost of bringing and enforcing such a claim or
action may be too high or not in the best interest of our company or our stockholders. In such cases, we may decide that the more prudent course of action is
to simply monitor the situation or initiate or seek some other non-litigious action or solution.

Changes in U.S. patent law or the patent law of other countries or jurisdictions could diminish the value of patents in general, thereby impairing our
ability to protect our products.

The United States has enacted and implemented wide-ranging patent reform legislation. The U.S. Supreme Court has ruled on several patent cases in
recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations.
In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect
to the value of patents, once obtained. Depending on actions by Congress, the federal courts, and the USPTO, the laws and regulations governing patents
could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce patents that we have licensed or that we might obtain in
the  future.  Similarly,  changes  in  patent  law  and  regulations  in  other  countries  or  jurisdictions  or  changes  in  the  governmental  bodies  that  enforce  them  or
changes in how the relevant governmental authority enforces patent laws or regulations may weaken our ability to obtain new patents or to enforce patents
that we have licensed or that we may obtain in the future.

We may not be able to protect our intellectual property rights throughout the world, which could impair our business.

Filing,  prosecuting,  and  defending  patents  covering  OC-01,  OC-02  and  any  future  product  candidate  throughout  the  world  would  be  prohibitively
expensive. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further,
may export otherwise infringing products to territories where we may have or obtain patent protection, but where patent enforcement is not as strong as that in
the United States. These unauthorized products may compete with our products in such jurisdictions and take away our market share where we do not have
any issued or licensed patents and any future patent claims or other intellectual property rights may not be effective or sufficient to prevent them from so
competing.

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

Because  we  expect  to  rely  on  third  parties  to  manufacture  OC-01,  OC-02  and  any  future  product  candidates,  and  we  expect  to  collaborate  with  third
parties on the continuing development of OC-01, OC-02 and any future product candidates, we must, at times, share trade secrets with them. We also expect
to conduct R&D programs that may require us to share trade secrets under the terms of our partnerships or agreements with CROs. We seek to protect our
proprietary  technology  in  part  by  entering  into  agreements  containing  confidentiality  and  use  restrictions  and  obligations,  including  material  transfer
agreements, consulting agreements, manufacturing and supply agreements, confidentiality agreements or other similar agreements with our advisors,

55

employees, contractors, CMOs, CROs, other service providers and consultants prior to disclosing proprietary information. These agreements typically limit
the rights of the third parties to use or disclose our confidential information, including our trade secrets. Despite the contractual provisions employed when
working with third parties, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by our
competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. Given that our proprietary
position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other unauthorized use or disclosure would
impair our competitive position and may have an adverse effect on our business and results of operations.

In addition, these agreements typically restrict the ability of our advisors, employees, third-party contractors CMOs, CROs, other service providers and
consultants to publish data potentially relating to our trade secrets, although our agreements may contain certain limited publication rights. Despite our efforts
to  protect  our  trade  secrets,  our  competitors  may  discover  our  trade  secrets,  either  through  breach  of  our  agreements  with  third  parties,  independent
development or publication of information by any of our third-party collaborators. A competitor’s discovery of our trade secrets would impair our competitive
position and have an adverse impact on our business.

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

We employ individuals who were previously employed at other biotechnology or pharmaceutical companies, or at research institutions. Although we seek
to protect our ownership of intellectual property rights by ensuring that our agreements with our employees, collaborators, and other third parties with whom
we  do  business  include  provisions  requiring  such  parties  to  assign  rights  in  inventions  to  us,  we  may  be  subject  to  claims  that  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 fail in defending any such claims, in addition
to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property.
Even if we are successful, litigation could result in substantial cost and be a distraction to our management and other employees.

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not

adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:

•

•

others may be able to make formulations or compositions that are the same as or similar to our current and future product candidates, but that are not
covered by the claims of the patents that we own;

others may be able to make product that is similar to our current and future product candidates we intend to commercialize that is not covered by the
patents that we exclusively licensed and have the right to enforce;

• we, any of our future licensors or collaborators might not have been the first to make the inventions covered by the issued patents or pending patent

applications that we own;

• we or any of our future licensor might not have been the first to file patent applications covering certain of our inventions;

•

•

•

•

others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property
rights;

it is possible that our future patent applications will not lead to issued patents;

issued  patents  that  we  own  may  not  provide  us  with  any  competitive  advantages,  or  may  be  held  invalid  or  unenforceable  as  a  result  of  legal
challenges;

our competitors might conduct research and development activities in the United States and other countries that provide a safe harbor from patent
infringement claims for certain research and development activities, as well as in countries where we do not have patent rights, and then use the
information learned from such activities to develop competitive products for sale in our major commercial markets; and

56

• we may not develop additional proprietary technologies that are patentable.

Any collaboration or partnership arrangements that we may enter into in the future may not be successful, which could adversely affect our ability to
develop and commercialize our products.

Any future collaborations that we enter into may not be successful. The success of our collaboration arrangements will depend heavily on the efforts and

activities of our collaborators. Collaborations are subject to numerous risks, which may include that:

•

•

•

•

collaborators have significant discretion in determining the efforts and resources that they will apply to collaborations;

collaborators  may  not  pursue  development  and  commercialization  of  our  products  or  may  elect  not  to  continue  or  renew  development  or
commercialization programs based on trial or test results, changes in their strategic focus due to the acquisition of competitive products, availability
of funding or other external factors, such as a business combination that diverts resources or creates competing priorities;

collaborators  could  independently  develop,  or  develop  with  third  parties,  products  that  compete  directly  or  indirectly  with  our  current  and  future
product candidates;

a collaborator with marketing, manufacturing and distribution rights to one or more products may not commit sufficient resources to or otherwise not
perform satisfactorily in carrying out these activities;

• we could grant exclusive rights to our collaborators that would prevent us from collaborating with others;

•

•

•

•

•

collaborators may not properly maintain or defend our intellectual property rights or may use our intellectual property or proprietary information in a
way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose
us to potential liability;

disputes  may  arise  between  us  and  a  collaborator  that  causes  the  delay  or  termination  of  the  research,  development  or  commercialization  of  our
current or future products or that results in costly litigation or arbitration that diverts management attention and resources;

collaborations may be terminated, and, if terminated, may result in a need for additional capital to pursue further development or commercialization
of the applicable current or future products;

collaborators may own or co-own intellectual property covering our products that results from our collaborating with them, and in such cases, we
would not have the exclusive right to develop or commercialize such intellectual property; and

a  collaborator’s  sales  and  marketing  activities  or  other  operations  may  not  be  in  compliance  with  applicable  laws  resulting  in  civil  or  criminal
proceedings.

If our future trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and
our business may be adversely affected.

We intend to use registered or unregistered trademarks or trade names to brand and market ourselves and our products. Our trademarks or trade names
may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to
these  trademarks  and  trade  names,  which  we  need  to  build  name  recognition  among  potential  partners  or  customers  in  our  markets  of  interest.  At  times,
competitors  may  adopt  trade  names  or  trademarks  similar  to  ours,  thereby  impeding  our  ability  to  build  brand  identity  and  possibly  leading  to  market
confusion.  In  addition,  there  could  be  potential  trade  name  or  trademark  infringement  claims  brought  by  owners  of  other  trademarks  or  trademarks  that
incorporate variations of our registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based
on  our  trademarks  and  trade  names,  then  we  may  not  be  able  to  compete  effectively  and  our  business  may  be  adversely  affected.  We  may  license  our
trademarks and trade names to third parties, such as distributors. Though these license agreements may provide guidelines for how our trademarks and trade
names may be used, a breach of these agreements or misuse of our trademarks and tradenames by our licensees may jeopardize our rights in or diminish the
goodwill associated with our trademarks and trade names. Our efforts to enforce or protect our proprietary rights related to trademarks,

57

trade names, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and diversion of
resources and could adversely affect our business, growth prospects, operating results and financial condition.

If  we  fail  to  comply  with  our  obligations  under  any  license,  collaboration  or  other  agreements,  including  our  license  agreement  with  Pfizer,  such
agreements may be terminated, we may be required to pay damages and we could lose intellectual property rights that are necessary for developing and
protecting our product candidates.

We currently and may in the future license from third parties certain intellectual property relating to current and future product candidates. If we breach
any material obligations, or use the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages and the licensor may
have  the  right  to  terminate  the  license,  which  could  result  in  us  being  unable  to  develop,  manufacture,  and  sell  products  that  are  covered  by  the  licensed
technology or enable a competitor to gain access to the licensed technology. Specifically, our license agreement with Pfizer can be terminated by Pfizer upon
60 days’ written notice for our uncured material breach or 30 days following non-payment or immediately upon our insolvency.

Disputes may arise between us and our licensors regarding intellectual property subject to a license agreement, including:

•

the scope of rights granted under the license agreement and other interpretation-related issues;

• whether  and  the  extent  to  which  our  technology  and  processes  infringe  on  intellectual  property  of  the  licensor  that  is  not  subject  to  the  licensing

agreement;

our right to sublicense patents and other rights to third parties;

our  diligence  obligations  with  respect  to  the  use  of  the  licensed  technology  in  relation  to  our  development  and  commercialization  of  our  product
candidates, and what activities satisfy those diligence obligations;
our right to transfer or assign the license; and

the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by any of our licensors and us and our
partners.

•

•

•

•

If disputes over intellectual property that we license prevent or impair our ability to maintain our licensing arrangements on acceptable terms, we may not

be able to successfully develop and commercialize the affected product candidates, which would have a material adverse effect on our business.

In addition, certain of our current or future agreements with third parties may limit or delay our ability to consummate certain transactions, may impact

the value of those transactions, or may limit our ability to pursue certain activities.

Further,  we  or  our  current  or  future  licensors,  if  any,  may  fail  to  identify  patentable  aspects  of  inventions  made  in  the  course  of  development  and
commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent
position. It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example
with  respect  to  proper  priority  claims,  inventorship,  claim  scope,  or  requests  for  patent  term  adjustments.  If  we  or  our  current  or  future  licensors  fail  to
establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our current or future licensors
are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised.
If there are material defects in the form, preparation, prosecution, or enforcement of our patents or patent applications, such patents may be invalid and/or
unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition
from third parties, which may have an adverse impact on our business.

In addition, even where we have the right to control patent prosecution of patents and patent applications under a license from third parties, we may still
be adversely affected or prejudiced by actions or inactions of our predecessors or licensors and their counsel that took place prior to us assuming control over
patent prosecution.

Our acquired technologies and current or future licensed technology may be subject to retained rights. Our predecessors or licensors may retain certain
rights under their agreements with us, including the right to use the underlying technology for noncommercial academic and research use, to publish general
scientific  findings  from  research  related  to  the  technology,  and  to  make  customary  scientific  and  scholarly  disclosures  of  information  relating  to  the
technology. It is difficult to monitor whether

58

our  predecessors  or  future  licensors  limit  their  use  of  the  technology  to  these  uses,  and  we  could  incur  substantial  expenses  to  enforce  our  rights  to  our
licensed technology in the event of misuse.

If we are limited in our ability to utilize acquired technologies or current or future licensed technologies, or if we lose our rights to critical acquired or in-
licensed  technology,  we  may  be  unable  to  successfully  develop,  out-license,  market  and  sell  our  products,  which  could  prevent  or  delay  new  product
introductions.  Our  business  strategy  depends  on  the  successful  development  of  acquired  technologies,  and  current  or  future  licensed  technology,  into
commercial products. Therefore, any limitations on our ability to utilize these technologies may impair our ability to develop, out-license or market and sell
our product candidates.

Risks Related to Government Regulation

If the FDA does not conclude that OC-01 satisfies the requirements under Section 505(b)(2) of the Federal Food Drug and Cosmetics Act (FFDCA), or if
the requirements for such product candidates under Section 505(b)(2) are not as we expect, the approval pathway for those product candidates may take
longer, cost more or entail greater complications and risks than anticipated, and may not be successful.

We intend to seek FDA approval through the Section 505(b)(2) regulatory pathway for OC-01. Section 505(b)(2) of the FFDCA permits the submission
of a New Drug Application (NDA) where some or all of the data required for approval comes from studies not conducted by or for the applicant and for
which the applicant has not obtained a right of reference. Our ability to rely on certain of the FDA’s findings of safety and effectiveness in approval of another
NDA or on studies published in the scientific literature will depend on our ability to demonstrate the relevance to OC-01.

In particular, we conducted ZEN, a comparative pharmacokinetic "bridge" trial, to evaluate the relative bioavailability of varenicline administered as a
nasal spray (OC-01) compared to varenicline administered orally (Chantix) in order to reference certain FDA conclusions regarding the safety of varenicline
from the Agency’s review of the Chantix NDA. If the FDA does not accept or disagrees with our conclusions from ZEN or the data required for approval of
our Section 505(b)(2) NDA are different than anticipated, we may be required to conduct additional development activities or studies or provide additional
data and information to pursue the 505(b)(2) regulatory pathway on our proposed timeline. Such delays could result in new competitive products reaching the
market faster than OC-01, which could materially adversely impact our competitive position and growth prospects.

The regulatory approval processes of the FDA, EMA and other comparable foreign regulatory authorities are lengthy, time consuming and inherently
unpredictable. If we are ultimately unable to obtain regulatory approval for our product candidates, we will be unable to generate product revenue and
our business will be substantially harmed.

The time required to obtain approval by the FDA, EMA and other comparable foreign regulatory authorities is unpredictable, typically takes many years
following  the  commencement  of  clinical  trials  and  depends  upon  numerous  factors,  including  the  type,  complexity  and  novelty  of  the  product  candidates
involved. In addition, approval policies, regulations or the type and amount of clinical data necessary to gain approval may change during the course of a
product  candidate’s  clinical  development  and  may  vary  among  jurisdictions,  which  may  cause  delays  in  the  approval  or  the  decision  not  to  approve  an
application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data
are insufficient for approval and require additional preclinical, clinical or other data. Even if we eventually complete clinical testing and receive approval of
any regulatory filing for our product candidates, the FDA, EMA and other comparable foreign regulatory authorities may approve our product candidates for
a more limited indication or a narrower patient population than we originally requested. We have not submitted for, or obtained, regulatory approval for any
product candidate, and it is possible that none of our existing product candidates or any product candidates we may seek to develop in the future will ever
obtain regulatory approval.

Further, development of our product candidates and/or regulatory approval may be delayed for reasons beyond our control. For example, a U.S. federal
government  shutdown  or  budget  sequestration,  such  as  ones  that  occurred  during  2013,  2018  and  2019,  may  result  in  significant  reductions  to  the  FDA’s
budget,  employees  and  operations,  which  may  lead  to  slower  response  times  and  longer  review  periods,  potentially  affecting  our  ability  to  progress
development of our product candidates or obtain regulatory approval for our product candidates. In addition, our competitors may file citizens’ petitions with
the FDA in an attempt to persuade the FDA that our product candidates, or the clinical trials that support their approval, contain deficiencies. Such actions by
our competitors could delay or even prevent the FDA from approving any of our NDAs.

Applications for our product candidates could fail to receive regulatory approval for many reasons, including the following:

•

the FDA, EMA or other comparable foreign regulatory authorities may disagree with the design, implementation or results of our clinical trials;

59

•

•

•

•

the  FDA,  EMA  or  other  comparable  foreign  regulatory  authorities  may  determine  that  our  product  candidates  are  not  safe  and  effective,  only
moderately effective or have undesirable or unintended side effects, toxicities or other characteristics that preclude our obtaining marketing approval
or prevent or limit commercial use;

the population studied in the clinical trial may not be sufficiently broad or representative to assure efficacy and safety in the full population for which
we seek approval;

the FDA, EMA or other comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies or clinical
trials;

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

• we may be unable to demonstrate to the FDA, EMA or other comparable foreign regulatory authorities that a product candidate’s risk-benefit ratio

for its proposed indication is acceptable;

•

•

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

the  approval  policies  or  regulations  of  the  FDA,  EMA  or  other  comparable  foreign  regulatory  authorities  may  significantly  change  in  a  manner
rendering our clinical data insufficient for approval.

This lengthy approval process, as well as the unpredictability of the results of clinical trials, may result in our failing to obtain regulatory approval to

market any of our product candidates, which could materially affect our business, financial condition, results of operations and growth prospects.

We may face difficulties from changes to current regulations and future legislation.

In the United States, the European Union and other jurisdictions, there have been, and we expect there will continue to be, a number of legislative and
regulatory changes and proposed changes to the healthcare system that could affect our future results of operations. Existing regulatory policies may change
and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the
likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If
we  are  slow  or  unable  to  adapt  to  changes  in  existing  requirements  or  the  adoption  of  new  requirements  or  policies,  or  if  we  are  not  able  to  maintain
regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.

For example, in March 2010, the Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act
of 2010 (collectively, the ACA), was passed, which substantially changes the way healthcare is financed by both the government and private insurers, and
significantly  impacts  the  U.S.  pharmaceutical  industry.  Some  of  the  provisions  of  the  ACA  have  yet  to  be  implemented,  and  there  have  been  judicial,
Congressional  and  executive  branch  challenges  to  certain  aspects  of  the  ACA,  as  well  as  recent  efforts  by  the  Trump  administration  to  repeal  or  replace
certain aspects of the ACA. Since January 2017, President Trump has signed two Executive Orders and other directives designed to delay the implementation
of certain provisions of the ACA or otherwise circumvent some of the requirements for health insurance mandated by the ACA. Concurrently, Congress has
considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, two
bills  affecting  the  implementation  of  certain  taxes  under  the  ACA  have  passed.  On  December  22,  2017,  President  Trump  signed  into  law  federal  tax
legislation commonly referred to as the Tax Cuts and Jobs Act (Tax Act) which includes a provision repealing, effective January 1, 2019, the tax-based shared
responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly
referred  to  as  the  “individual  mandate.”  On  January  22,  2018,  President  Trump  signed  a  continuing  resolution  on  appropriations  for  fiscal  year  2018  that
delayed the implementation of certain ACA-mandated fees, including the so-called “Cadillac” tax on certain high cost employer-sponsored insurance plans,
the annual fee imposed on certain health insurance providers based on market share, and the medical device excise tax on non-exempt medical devices. The
Bipartisan Budget Act of 2018, among other things, amended the ACA, effective January 1, 2019, to close the coverage gap in most Medicare Part D drug
plans. In July 2018, the Centers for Medicare and Medicaid Services (CMS) published a final rule permitting further collections and payments to and from
certain ACA-qualified health plans and health insurance issuers under the ACA risk adjustment

60

program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment.

On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was
repealed by Congress as part of the Tax Act. While the Texas U.S. District Court Judge, as well as the Trump administration and CMS, have stated that the
ruling will have no immediate effect pending appeal of the decision, it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace
the ACA will impact the ACA and our business.

In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. These changes included aggregate
reductions to Medicare payments to providers of up to 2% per fiscal year, effective April 1, 2013, which, due to subsequent legislative amendments, will stay
in  effect  through  2027  unless  additional  Congressional  action  is  taken.  In  January  2013,  the  American  Taxpayer  Relief  Act  of  2012  was  signed  into  law,
which, among other things, reduced Medicare payments to several providers, and increased the statute of limitations period for the government to recover
overpayments  to  providers  from  three  to  five  years.  These  new  laws  may  result  in  additional  reductions  in  Medicare  and  other  healthcare  funding,  which
could have a material adverse effect on customers for our product candidates, if approved, and accordingly, our financial operations.

Moreover,  payment  methodologies  may  be  subject  to  changes  in  healthcare  legislation  and  regulatory  initiatives.  There  has  been  heightened
governmental  scrutiny  recently  over  the  manner  in  which  drug  manufacturers  set  prices  for  their  marketed  products,  which  has  resulted  in  several
Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing,
review  the  relationship  between  pricing  and  manufacturer  patient  programs,  and  reform  government  program  reimbursement  methodologies  for  drug
products.  For  example,  at  the  federal  level,  the  Trump  administration  released  a  “Blueprint”  to  lower  drug  prices  and  reduce  out-of-pocket  costs  of
prescription  drugs  that  contains  additional  proposals  to  increase  manufacturer  competition,  increase  the  negotiating  power  of  certain  federal  healthcare
programs,  incentivize  manufacturers  to  lower  the  list  price  of  their  products  and  reduce  the  out-of-pocket  costs  of  drug  products  paid  by  consumers.
Additionally,  on  January  31,  2019,  HHS  Office  of  Inspector  General  proposed  modifications  to  federal  Anti-Kickback  Statute  safe  harbors  which,  among
other things, may affect rebates paid by manufactures to Medicare Part D plan sponsors, Medicaid managed care organizations, and those entities’ pharmacy
benefit managers, the purpose of which is to further reduce the cost of drug products to consumers. At the state level, legislatures have increasingly passed
legislation  and  implemented  regulations  designed  to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient  reimbursement
constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  designed  to
encourage importation from other countries and bulk purchasing.

We expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and
in additional downward pressure on the price that we receive for any approved product. Any reduction in reimbursement from Medicare or other government
programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms
may prevent us from being able to generate revenue, attain profitability or commercialize our product candidates.

In  the  European  Union,  similar  political,  economic  and  regulatory  developments  may  affect  our  ability  to  profitably  commercialize  our  product
candidates,  if  approved.  In  addition  to  continuing  pressure  on  prices  and  cost  containment  measures,  legislative  developments  at  the  European  Union  or
member  state  level  may  result  in  significant  additional  requirements  or  obstacles  that  may  increase  our  operating  costs.  The  delivery  of  healthcare  in  the
European Union, including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost exclusively a matter
for national, rather than EU, law and policy. National governments and health service providers have different priorities and approaches to the delivery of
health  care  and  the  pricing  and  reimbursement  of  products  in  that  context.  In  general,  however,  the  healthcare  budgetary  constraints  in  most  EU  member
states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. Coupled with ever- increasing EU and
national  regulatory  burdens  on  those  wishing  to  develop  and  market  products,  this  could  prevent  or  delay  marketing  approval  of  our  product  candidates,
restrict or regulate post-approval activities and affect our ability to commercialize our product candidates, if approved.

Legislative  and  regulatory  proposals  have  been  made  to  expand  post-approval  requirements  and  restrict  sales  and  promotional  activities  for
biotechnology products. We cannot be sure whether additional legislative changes will be enacted, or whether FDA regulations, guidance or interpretations
will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be. In addition, increased scrutiny by
Congress of the FDA approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and
post-marketing testing and other requirements.

61

Our  employees,  independent  contractors,  consultants,  commercial  collaborators,  principal  investigators,  CROs,  suppliers  and  vendors  may  engage  in
misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk that our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs, suppliers
and  vendors  may  engage  in  misconduct  or  other  improper  activities.  Misconduct  by  these  parties  could  include  failures  to  comply  with  FDA  regulations,
provide  accurate  information  to  the  FDA,  comply  with  federal  and  state  health  care  fraud  and  abuse  laws  and  regulations,  comply  with  data  privacy  and
security  laws  and  accurately  report  financial  information  or  data  or  disclose  unauthorized  activities  to  us.  In  particular,  sales,  marketing  and  business
arrangements in the health care industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other
abusive  practices.  These  laws  and  regulations  may  restrict  or  prohibit  a  wide  range  of  pricing,  discounting,  marketing  and  promotion,  sales  commission,
customer incentive programs and other business arrangements. Misconduct by these parties could also involve the improper use of information obtained in the
course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. Although we have adopted a code of business conduct
and  ethics  with  respect  to  our  employees,  agents  and  contractors,  it  is  not  always  possible  to  identify  and  deter  misconduct  by  these  parties,  and  the
precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from
governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. Additionally, we are subject to the
risk that a person or government could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are
not  successful  in  defending  ourselves  or  asserting  our  rights,  those  actions  could  have  a  significant  impact  on  our  business,  including  the  imposition  of
significant  penalties,  including  civil,  criminal  and  administrative  penalties,  damages,  fines,  disgorgement,  individual  imprisonment,  exclusion  from
participation in government funded healthcare programs, such as Medicare and Medicaid, integrity oversight and reporting obligations, contractual damages,
reputational harm, diminished profits and future earnings and the curtailment or restructuring of our 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  and  any  contract  manufacturers  and  suppliers  we  engage  are  subject  to  numerous  federal,  state,  and  local  environmental,  health,  and  safety  laws,
regulations, and permitting requirements, including those governing laboratory procedures; the generation, handling, use, storage, treatment, and disposal of
hazardous and regulated materials and wastes; the emission and discharge of hazardous materials into the ground, air, and water; and employee health and
safety. Our operations involve the use of hazardous and flammable materials, including chemicals and biological and radioactive materials. Our operations
also  produce  hazardous  waste.  We  generally  contract  with  third  parties  for  the  disposal  of  these  materials  and  wastes.  We  cannot  eliminate  the  risk  of
contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable
for any resulting damages, and any liability could exceed our resources. Under certain environmental laws, we could be held responsible for costs relating to
any contamination at our current or past facilities and at third-party facilities. We also could incur significant costs associated with civil or criminal fines and
penalties.

Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental laws and regulations may impair
our research, product development and manufacturing efforts. In addition, we cannot entirely eliminate the risk of accidental injury or contamination from
these  materials  or  waste  Although  we  maintain  workers’  compensation  insurance  to  cover  us  for  costs  and  expenses  we  may  incur  due  to  injuries  to  our
employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not currently
maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of hazardous and
flammable materials, including chemicals and biological materials. Accordingly, in the event of contamination or injury, we could be held liable for damages
or  be  penalized  with  fines  in  an  amount  exceeding  our  resources,  and  our  clinical  trials  or  regulatory  approvals  could  be  suspended,  which  could  have  a
material adverse effect on our business, financial condition, results of operations and growth prospects.

In addition, we may incur substantial costs in order 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 commercialization efforts. Failure to comply with these laws and regulations also
may result in substantial fines, penalties or other sanctions.

Obtaining  and  maintaining  regulatory  approval  of  our  product  candidates  in  one  jurisdiction  does  not  mean  that  we  will  be  successful  in  obtaining
regulatory approval of our product candidates in other jurisdictions. The FDA, EMA and other comparable foreign regulatory authorities may not accept
data from trials conducted in locations outside of their jurisdiction.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain

regulatory approval in any other jurisdiction. For example, even if the FDA or EMA grants

62

marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and
promotion and reimbursement of the product candidate in those countries. However, a failure or delay in obtaining regulatory approval in one jurisdiction
may have a negative effect on the regulatory approval process in others. Approval procedures vary among jurisdictions and can involve requirements and
administrative review periods different from those in the United States, including additional preclinical studies or clinical trials as clinical trials conducted in
one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must
be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also
subject to approval.

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

In  addition,  we  may  choose  to  conduct  international  clinical  trials.  The  acceptance  of  study  data  by  the  FDA,  EMA  or  other  comparable  foreign
regulatory  authority  from  clinical  trials  conducted  outside  of  their  respective  jurisdictions  may  be  subject  to  certain  conditions.  In  cases  where  data  from
foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the
basis  of  foreign  data  alone  unless  (1)  the  data  are  applicable  to  the  U.S.  population  and  U.S.  medical  practice;  (2)  the  trials  are  performed  by  clinical
investigators  of  recognized  competence  and  pursuant  to  GCP  regulations;  and  (3)  audits  by  regulatory  authorities  of  the  clinical  data  do  not  identify
significant data integrity issues. Additionally, the FDA’s clinical trial requirements, including the adequacy of the patient population studied and statistical
powering, must be met. In addition, such foreign trials are subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There
can  be  no  assurance  that  the  FDA,  EMA  or  any  applicable  foreign  regulatory  authority  will  accept  data  from  trials  conducted  outside  of  its  applicable
jurisdiction. If the FDA, EMA or any applicable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which
would  be  costly  and  time-consuming  and  delay  aspects  of  our  business  plan,  and  which  may  result  in  our  product  candidates  not  receiving  approval  or
clearance for commercialization in the applicable jurisdiction.

Our business activities may be subject to the FCPA and similar anti-bribery and anti-corruption laws of other countries in which we operate, as well as
U.S.  and  certain  foreign  export  controls,  trade  sanctions,  and  import  laws  and  regulations.  Compliance  with  these  legal  requirements  could  limit  our
ability to compete in foreign markets and subject us to liability if we violate them.

We recently completed a trial and may plan to initiate additional trials in countries other than the United States. Our business activities may be subject to
the FCPA and similar anti-bribery or anti-corruption laws, regulations or rules of other countries in which we operate. The FCPA generally prohibits offering,
promising, giving or authorizing others to give anything of value, either directly or indirectly, to a non-U.S. government official in order to influence official
action or otherwise obtain or retain business. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect
the  transactions  of  the  corporation  and  to  devise  and  maintain  an  adequate  system  of  internal  accounting  controls.  Our  business  is  heavily  regulated  and
therefore  involves  significant  interaction  with  public  officials,  including  officials  of  non-U.S.  governments.  Additionally,  in  many  other  countries,  the
healthcare  providers,  including  ECPs,  who  prescribe  pharmaceuticals  are  employed  by  their  government,  and  the  purchasers  of  pharmaceuticals  are
government  entities;  therefore,  our  dealings  with  these  prescribers  and  purchasers  are  subject  to  regulation  under  the  FCPA.  Recently  the  SEC  and
Department of Justice have increased their FCPA enforcement activities with respect to biotechnology and pharmaceutical companies. There is no certainty
that all of our employees, agents or contractors, or those of our affiliates, will comply with all applicable laws and regulations, particularly given the high
level of complexity of these laws. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees,
the  closing  down  of  our  facilities,  requirements  to  obtain  export  licenses,  cessation  of  business  activities  in  sanctioned  countries,  implementation  of
compliance programs and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our products in
one or more countries and could materially damage our reputation, our brand, our international activities, our ability to attract and retain employees and our
business, growth prospects, operating results and financial condition.

In addition, our products may be subject to U.S. and foreign export controls, trade sanctions and import laws and regulations. Governmental regulation of
the import or export of our products, or our failure to obtain any required import or export authorization for our products, when applicable, could harm our
international  sales  and  adversely  affect  our  revenue.  Compliance  with  applicable  regulatory  requirements  regarding  the  export  of  our  products  may  create
delays  in  the  introduction  of  our  products  in  international  markets  or,  in  some  cases,  prevent  the  export  of  our  products  to  some  countries  altogether.
Furthermore, U.S. export control laws and economic sanctions prohibit the shipment of certain products and services to countries, governments, and persons
targeted by U.S. sanctions. If we fail to comply with export and import regulations and such economic sanctions, we may

63

be fined or other penalties could be imposed, including a denial of certain export privileges. Moreover, any new export or import restrictions, new legislation
or shifting approaches in the enforcement or scope of existing regulations, or in the countries, persons, or technologies targeted by such regulations, could
result in decreased use of our products by, or in our decreased ability to export our products to existing or potential customers with international operations.
Any decreased use of our products or limitation on our ability to export or sell access to our products would likely adversely affect our business.

The FDA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses.

If any of our product candidates are approved and we are found to have improperly promoted off-label uses of those products, we may become subject to
significant liability. The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription products, such as our
product candidates, if approved. In particular, a product may not be promoted for uses that are not approved by the FDA or such other regulatory agencies as
reflected in the product’s approved labeling. For example, if we receive marketing approval for OC-01 as a treatment for the signs and symptoms of DED,
physicians may nevertheless use our product for their patients in a manner that is inconsistent with the approved label. If we are found to have promoted such
off-label uses, we may become subject to significant liability. The U.S. federal government has levied large civil and criminal fines against companies for
alleged  improper  promotion  of  off-label  use  and  has  enjoined  several  companies  from  engaging  in  off-label  promotion.  The  FDA  has  also  requested  that
companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. If we cannot successfully
manage the promotion of our product candidates, if approved, we could become subject to significant liability, which would materially adversely affect our
business, growth prospects, operating results and financial condition.

Inadequate  funding  for  the  FDA,  the  SEC  and  other  government  agencies  could  hinder  their  ability  to  hire  and  retain  key  leadership  and  other
personnel,  prevent  new  products  and  services  from  being  developed  or  commercialized  in  a  timely  manner  or  otherwise  prevent  those  agencies  from
performing normal business functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels,
ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. Average review times at the FDA
have fluctuated in recent years as a result. In addition, government funding of the Securities and Exchange Commission (SEC) and other government agencies
on which our operations may rely, including those that fund research and development activities is subject to the political process, which is inherently fluid
and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government
agencies, which would adversely affect our business. For example, in recent years, including in 2013, 2018 and 2019, the U.S. government shut down several
times  and  certain  regulatory  agencies,  such  as  the  FDA  and  the  SEC,  have  had  to  furlough  critical  FDA,  SEC  and  other  government  employees  and  stop
critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory
submissions, which could have a material adverse effect on our business. Further, in our operations as a public company, future government shutdowns could
impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.

Our operations, and those of our CROs, CMOs, suppliers, and other contractors and consultants, could be subject to wildfires, earthquakes, tsunamis,
power shortages or outages, floods or monsoons, public health crises, such as pandemics and epidemics, political crises, such as terrorism, war (including
trade wars), political instability or other conflict, and other natural or man-made disasters or other events outside of our control that can disrupt business. The
occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs and expenses. For example,
we  rely  on  third-party  manufacturers  to  produce  and  process  our  product  candidates.  Our  ability  to  obtain  supplies  of  our  product  candidates  or  other
necessary supplies could be disrupted if the operations of these suppliers are affected by a man-made or natural disaster or other business interruption. All of
our operations including our corporate headquarters are located in a single location in Princeton, New Jersey. Damage or extended periods of interruption to
our corporate, development or research facilities due to fire, natural disaster, power loss, communications failure, unauthorized entry or other events could
cause us to cease or delay development of some or all of our product candidates. Although we maintain property damage and business interruption insurance
coverage on these facilities, our insurance might not cover all losses under such circumstances and our business may be seriously harmed by such delays and
interruption.

Risks Related to Reliance on Third Parties

64

We rely on third parties to conduct our clinical trials and those third parties may not perform satisfactorily, including failing to meet deadlines for the
completion of such trials, research and studies.

We  do  not  have  the  ability  to  independently  conduct  our  clinical  trials.  We  currently  rely  on  third  parties,  such  as  CROs,  clinical  data  management
organizations,  medical  institutions  and  clinical  investigators,  to  conduct  our  current  and  planned  clinical  trials  of  OC-01  and  OC-02,  and  we  expect  to
continue  to  rely  upon  third  parties  to  conduct  additional  clinical  trials  of  OC-01,  OC-02  and  potential  future  product  candidates.  Third  parties  have  a
significant role in the conduct of our clinical trials and the subsequent collection and analysis of data. These third parties are not our employees, and except
for remedies available to us under our agreements with such third party, we have limited ability to control the amount or timing of resources that any such
third  party  will  devote  to  our  clinical  trials.  Some  of  these  third  parties  may  terminate  their  engagements  with  us  at  any  time.  If  we  need  to  enter  into
alternative arrangements with a third party, it would delay our development activities.

Our reliance on these third parties for such development activities will reduce our control over these activities but will not relieve us of our regulatory
responsibilities.  For  example,  we  will  remain  responsible  for  ensuring  that  each  of  our  clinical  trials  is  conducted  in  accordance  with  the  general
investigational  plan  and  protocols  for  the  trial.  Moreover,  the  FDA  requires  us  to  comply  with  GCP  standards,  regulations  for  conducting,  recording  and
reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial
participants  are  protected.  The  EMA  also  requires  us  to  comply  with  similar  standards.  Regulatory  authorities  enforce  these  GCP  requirements  through
periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of our CROs fail to comply with applicable GCP requirements, the
clinical data generated in our clinical trials may be deemed unreliable and the FDA, EMA or comparable foreign regulatory authorities may require us to
perform additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a given regulatory authority,
such regulatory authority will determine that any of our clinical trials comply with GCP regulations. In addition, our clinical trials must be conducted with
product produced under current cGMP regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the
marketing  approval  process.  We  also  are  required  to  register  certain  ongoing  clinical  trials  and  post  the  results  of  certain  completed  clinical  trials  on  a
government-sponsored database, ClinicalTrials.gov, within certain timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal
sanctions.

The  third  parties  we  rely  on  for  these  services  may  also  have  relationships  with  other  entities,  some  of  which  may  be  our  competitors.  If  these  third
parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements
or our stated protocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and will not be able to,
or may be delayed in our efforts to, successfully commercialize our product candidates.

We contract with third parties for the production of our product candidates for preclinical studies and our ongoing clinical trials, and expect to continue
to do so for additional clinical trials and ultimately for commercialization. This reliance on third parties increases the risk that we will not have sufficient
quantities of our product candidates or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization
efforts.

We  do  not  currently  have  the  infrastructure  or  internal  capability  to  manufacture  supplies  of  our  product  candidates  for  use  in  development  and
commercialization. We rely, and expect to continue to rely, on third-party manufacturers for the production of our product candidates for preclinical studies
and clinical trials under the guidance of members of our organization. We do not have long-term supply agreements. If we were to experience an unexpected
loss of supply of OC-01, OC-02 or any of our future product candidates for any reason, whether as a result of manufacturing, supply or storage issues or
otherwise, we could experience delays, disruptions, suspensions or terminations of, or be required to restart or repeat, any pending or ongoing clinical trials.

We expect to continue to rely on third-party manufacturers for the commercial supply of any of our product candidates for which we obtain marketing
approval. We may be unable to maintain or establish required agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able
to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including:

•

•

•

the failure of the third party to manufacture our product candidates according to our schedule, or at all, including if our third-party contractors give
greater priority to the supply of other products over our product candidates or otherwise do not satisfactorily perform according to the terms of the
agreements between us and them;
the termination or nonrenewal of arrangements or agreements by our third-party contractors at a time that is costly or inconvenient for us;

the breach by the third-party contractors of our agreements with them;

65

•

•

•

•

•

the  failure  of  third-party  contractors  to  comply  with  applicable  regulatory  requirements,  including  manufacturing  drug  supply  pursuant  to  strictly
enforced cGMPs;

the failure of the third party to manufacture our product candidates according to our specifications;

the  mislabeling  of  clinical  supplies,  potentially  resulting  in  the  wrong  dose  amounts  being  supplied  or  active  drug  or  placebo  not  being  properly
identified;

clinical  supplies  not  being  delivered  to  clinical  sites  on  time,  leading  to  clinical  trial  interruptions,  or  of  drug  supplies  not  being  distributed  to
commercial vendors in a timely manner, resulting in lost sales; and

the misappropriation of our proprietary information, including our trade secrets and know-how.

We  do  not  have  complete  control  over  all  aspects  of  the  manufacturing  process  of,  and  are  dependent  on,  our  contract  manufacturing  partners  for
compliance with cGMP regulations for manufacturing both active drug substances and finished drug products. Third-party manufacturers may not be able to
comply with cGMP regulations or similar regulatory requirements outside of the United States. If our contract manufacturers cannot successfully manufacture
material that conforms to our specifications and the strict regulatory requirements of the FDA, EMA or others, they will not be able to secure and/or maintain
marketing approval for their manufacturing facilities. In addition, we do not have control over the ability of our contract manufacturers to maintain adequate
quality control, quality assurance and qualified personnel. If the FDA, EMA or a comparable foreign regulatory authority does not approve these facilities for
the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which
would significantly impact our ability to develop, obtain marketing approval for or market our product candidates, if approved. Our failure, or the failure of
our  third-party  manufacturers,  to  comply  with  applicable  regulations  could  result  in  sanctions  being  imposed  on  us,  including  fines,  injunctions,  civil
penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of our product candidates, operating restrictions and criminal
prosecutions, any of which could significantly and adversely affect supplies of our product candidates and harm our business and results of operations.

We currently rely on single source manufacturers and suppliers for the supply of OC-01 and OC-02. If we decide to move to different or add additional
manufacturers and suppliers in the future, any such transition or addition would require significant efforts in testing and validating the manufacturing and
formulation process and could result in delays or other issues, which could have an adverse effect on the supply of our product candidates.

Our current and anticipated future dependence upon others for the manufacture of our product candidates may adversely affect our future profit margins

and our ability to commercialize any product candidates that receive marketing approval on a timely and competitive basis.

We  may  pursue  collaborations  with  third  parties  for  the  development  or  commercialization  of  our  product  candidates.  If  we  decide  to  pursue
collaborations,  but  are  not  able  to  establish  those  collaborations  on  commercially  reasonable  terms,  we  may  have  to  alter  our  development  and
commercialization  plans.  If  we  do  enter  into  collaborations  that  are  not  successful,  we  may  not  be  able  to  capitalize  on  the  market  potential  of  these
product candidates.

Our development programs and the potential commercialization of our product candidates will require substantial additional cash to fund expenses. We
may  seek  to  selectively  form  collaborations  to  expand  our  capabilities,  potentially  accelerate  research  and  development  activities  and  provide  for
commercialization activities by third parties. Any of these relationships may require us to incur non-recurring and other charges, increase our near and long-
term expenditures, issue securities that dilute our existing stockholders, or disrupt our management and business.

We  would  face  significant  competition  in  seeking  appropriate  collaborators  and  the  negotiation  process  is  time-consuming  and  complex.  Whether  we
reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms
and  conditions  of  the  proposed  collaboration  and  the  proposed  collaborator’s  evaluation  of  a  number  of  factors.  Those  factors  may  include  the  design  or
results  of  clinical  trials,  the  likelihood  of  approval  by  the  FDA,  EMA  or  comparable  foreign  regulatory  authorities,  the  potential  market  for  the  subject
product  candidate,  the  costs  and  complexities  of  manufacturing  and  delivering  such  product  candidate  to  patients,  the  potential  of  competing  drugs,  the
existence of uncertainty with respect to our ownership of intellectual property and industry and market conditions generally. The potential collaborator may
also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such collaboration
could be more attractive than the one with us for our product candidate. Further, we may not be successful in our efforts to establish a collaboration or other
alternative arrangements for future product

66

candidates because they may be deemed to be at too early of a stage of development for collaborative effort and third parties may not view them as having the
requisite potential to demonstrate safety and efficacy.

In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced
number of potential future collaborators. Even if we are successful in entering into a collaboration, the terms and conditions of that collaboration may restrict
us from entering into future agreements on certain terms with potential collaborators.

If and when we seek to enter into collaborations, we may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are
unable  to  do  so,  we  may  have  to  curtail  the  development  of  a  product  candidate,  reduce  or  delay  its  development  program  or  one  or  more  of  our  other
development  programs,  delay  its  potential  commercialization  or  reduce  the  scope  of  any  sales  and  marketing  activities,  or  increase  our  expenditures  and
undertake  development  or  commercialization  activities  at  our  own  expense.  If  we  elect  to  increase  our  expenditures  to  fund  development  or
commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not
have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate product revenue.

Our  business  operations  and  current  and  future  relationships  with  healthcare  professionals,  clinical  investigators,  consultants,  patient  organizations,
customers, CROs and third party payors in connection with our current and future business activities may be subject to federal and state healthcare fraud
and abuse laws, false claims laws, transparency laws, government price reporting, and health information privacy and security laws, which could expose
us  to,  among  other  things,  criminal  sanctions,  civil  penalties,  contractual  damages,  exclusion  from  governmental  healthcare  programs,  reputational
harm, administrative burdens and diminished profits and future earnings.

Healthcare providers and third-party payors play a primary role in the recommendation and prescription of any product candidates for which we obtain
marketing approval. Our current and future arrangements with healthcare professionals, including ECPs, clinical investigators, CROs, third-party payors and
customers  may  expose  us  to  broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and  regulations  that  may  constrain  the  business  or  financial
arrangements  and  relationships  through  which  we  market,  sell  and  distribute  our  products  for  which  we  obtain  marketing  approval.  Restrictions  under
applicable federal and state healthcare laws and regulations include the following:

•

•

•

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

the federal civil and criminal false claims and civil monetary penalties laws, including the civil False Claims Act, which can be enforced by private
citizens through civil whistleblower or qui tam actions, prohibit individuals or entities from, among other things, knowingly presenting, or causing to
be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an
obligation to pay money to the federal government;

the federal Health Insurance Portability and Accountability Act of 1996 (HIPAA) prohibits, among other things, executing or attempting to execute a
scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;

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

•

•

•

federal  consumer  protection  and  unfair  competition  laws,  which  broadly  regulate  marketplace  activities  and  activities  that  potentially  harm
consumers;

the FDCA, which prohibits, among other things, the adulteration or misbranding of drugs, biologics and medical devices;

the federal Physician Payments Sunshine Act requires applicable manufacturers of covered drugs, devices, biologics and medical supplies for which
payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to annually report to CMS
information regarding payments and other transfers of value to

67

physicians and teaching hospitals as well as information regarding ownership and investment interests held by physicians and their immediate family
members. The information reported is publicly available on a searchable website, with disclosure required annually; and

•

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, may apply to sales and marketing arrangements
and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers.

Some  state  laws  require  biotechnology  companies  to  comply  with  the  biotechnology  industry’s  voluntary  compliance  guidelines  and  the  relevant
compliance  guidance  promulgated  by  the  federal  government  and  may  require  drug  manufacturers  to  report  information  related  to  payments  and  other
transfers  of  value  to  physicians  and  other  healthcare  providers  or  marketing  expenditures.  Some  state  laws  require  biotechnology  companies  to  report
information on the pricing of certain drug products. State and foreign laws also govern the privacy and security of health information in some circumstances,
many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts. For instance, the
collection  and  use  of  health  data  in  the  European  Union  is  governed  by  the  General  Data  Protection  Regulation  (GDPR),  which  extends  the  geographical
scope  of  EU  data  protection  law  to  non-EU  entities  under  certain  conditions,  tightens  existing  EU  data  protection  principles,  creates  new  obligations  for
companies and new rights for individuals. Failure to comply with the GDPR may result in substantial fines and other administrative penalties. The GDPR
may  increase  our  responsibility  and  liability  in  relation  to  personal  data  that  we  process  and  we  may  be  required  to  put  in  place  additional  mechanisms
ensuring  compliance  with  the  GDPR.  This  may  be  onerous  and  if  our  efforts  to  comply  with  GDPR  or  other  applicable  EU  laws  and  regulations  are  not
successful, it could adversely affect our business in the European Union.

Efforts to ensure that our current and future business arrangements with third parties will comply with applicable healthcare laws and regulations will
involve  on-going  substantial  costs.  It  is  possible  that  governmental  authorities  will  conclude  that  our  business  practices,  including  the  provision  of  stock
options as compensation for consulting services to physicians and other healthcare providers, some of whom may be in a position to recommend, purchase
and/or prescribe our product candidates, if approved, may not comply with current or future statutes, regulations or case law involving applicable fraud and
abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that
may apply to us, we may be subject to significant penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement, individual
imprisonment, exclusion from participation in government funded healthcare programs, such as Medicare and Medicaid or similar programs in other countries
or  jurisdictions,  integrity  oversight  and  reporting  obligations,  contractual  damages,  reputational  harm,  diminished  profits  and  future  earnings  and  the
curtailment or restructuring of our operations. Defending against any such actions can be costly, time-consuming and may require significant financial and
personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired.
Further, if any of the physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance with applicable
laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.

Risks Related to Ownership of Common Stock

We will need substantial additional funding in the future. If we are unable to raise capital when needed, or on acceptable terms, we may be forced to
delay, reduce and/or eliminate one or more of our research and development programs or future commercialization efforts.

Developing  pharmaceutical  products,  including  conducting  preclinical  studies  and  clinical  trials,  is  a  very  time-consuming,  expensive  and  uncertain
process that takes years to complete. Our operations have consumed significant amounts of cash since inception, and we expect our expenses to increase in
connection with our ongoing activities, particularly as we continue to conduct clinical trials of, and seek marketing approval for, OC-01, OC-02 and any other
future product candidates. Even if one or more of the product candidates that we develop is approved for commercial sale, we anticipate incurring significant
costs associated with commercializing any approved product candidate. Our expenses could increase beyond expectations if we are required by the FDA, the
EMA or other regulatory agencies to perform clinical trials or preclinical studies in addition to those that we currently anticipate. Other unanticipated costs
may  also  arise.  In  addition,  if  we  obtain  marketing  approval  for  any  of  our  product  candidates,  including  OC-01,  we  expect  to  incur  significant
commercialization  expenses  related  to  sales,  marketing,  manufacturing  and  distribution.  Because  the  design  and  outcome  of  our  planned  and  anticipated
clinical  trials  are  highly  uncertain,  we  cannot  reasonably  estimate  the  actual  amounts  necessary  to  successfully  complete  the  development  and
commercialization of any product candidate we develop. In addition, we have incurred and will continue to incur additional costs associated with operating as
a public company. Accordingly, we will need to obtain substantial additional funding in order to maintain our continuing operations.

68

As of December 31, 2019, we had $139.1 million in cash and cash equivalents. Although we believe that our available cash and cash equivalents will be
sufficient to fund our planned operations for at least 12 months following the date of this Annual Report on Form 10-K, this belief is based on assumptions
that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Changing circumstances, some of which may
be beyond our control, could cause us to consume capital significantly faster than we currently anticipate, and we may need to seek additional funds sooner
than planned.

Advancing the development of OC-01, OC-02 and any other future product candidates will require a significant amount of capital. Our existing cash and
cash equivalents may not be sufficient to fund all of the activities that are necessary to complete the development of OC-01, OC-02 and any other future
product candidates. We will continue to require additional capital to develop our product candidates and fund operations for the foreseeable future. We may
seek to raise capital through private or public equity or debt financings, collaborative or other arrangements with corporate sources, or through other sources
of financing, which may dilute our stockholders or restrict our operating activities. The amount of additional capital we will need to raise will depend on
many factors, including:

•

•

•

•

•

•

•

•

•

•

•

the scope, timing, rate of progress and costs of our drug discovery efforts, preclinical development activities, laboratory testing and clinical trials for
our product candidates;

the number and scope of clinical programs we decide to pursue;

the cost, timing and outcome of preparing for and undergoing regulatory review of our product candidates;

the scope and costs of development and commercial manufacturing activities;

the cost and timing associated with commercializing our product candidates, if they receive marketing approval;

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

the  costs  of  preparing,  filing  and  prosecuting  patent  applications,  maintaining  and  enforcing  our  intellectual  property  rights  and  defending
intellectual property-related claims;

our ability to establish and maintain collaborations on favorable terms, if at all;

our  efforts  to  enhance  operational  systems  and  our  ability  to  attract,  hire  and  retain  qualified  personnel,  including  personnel  to  support  the
development of our product candidates and, ultimately, the sale of our products, following FDA approval;

our implementation of operational, financial and management systems; and

the costs associated with being a public company.

We do not have any committed external source of funds. Adequate additional financing may not be available to us on acceptable terms, or at all. Our
failure to raise capital as and when needed or on acceptable terms would have a negative impact on our business, growth prospects, operating results and
financial condition and our ability to pursue our business strategy, and we may have to delay, reduce the scope of, suspend or eliminate one or more of our
research-stage programs, clinical trials or future commercialization efforts.

An active trading market for our common stock may not be sustained.

Prior to the closing of our IPO in November 2019, there was no public trading market for our common stock. Although our common stock is listed on the
NASDAQ  Global  Select  Market,  the  market  for  our  shares  has  demonstrated  varying  levels  of  trading  activity.  We  cannot  predict  the  prices  at  which  our
common stock will trade or whether an active trading market will be sustained in the future. The lack of an active market may impair investors’ ability to sell
their shares at the time they wish to sell them or at a price that they consider reasonable, may reduce the market value of their shares and may impair our
ability to raise capital.

If securities or industry analysts do not continue to publish research or reports, or if they publish adverse or misleading research or reports, regarding us,
our business or our market, our stock price and trading volume could decline.

69

The trading market for our common stock will be influenced by the research and reports that securities or industry analysts publish about us, our business
or our market. If no additional securities or industry analysts commence coverage of us, our stock price could be negatively impacted. If any of the analysts
who cover us issue adverse or misleading research or reports regarding us, our business model, our intellectual property, our stock performance or our market,
or if our operating results fail to meet the expectations of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us
or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to
decline.

The price of our stock may be volatile, and you could lose all or part of your investment.

The trading price of our common stock may be highly volatile and subject to wide fluctuations in response to various factors, some of which we cannot
control. The stock market in general, and pharmaceutical and biotechnology companies in particular, have experienced extreme price and volume fluctuations
that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect
the market price of our common stock, regardless of our actual operating performance. In addition to the factors discussed in this “Risk Factors” section and
elsewhere in this Annual Report on Form 10-K, these factors include:

•

•

•

•

•

•

•

•

•

•

the timing and results of preclinical studies and clinical trials of our product candidates or those of our competitors;

the success of competitive products or announcements by potential competitors of their product development efforts;

regulatory actions with respect to our products or our competitors’ products;

actual or anticipated changes in our growth rate relative to our competitors;

regulatory or legal developments in the United States and other countries;

developments or disputes concerning patent applications, issued patents or other proprietary rights;

the recruitment or departure of key personnel;

announcements by us or our competitors of significant acquisitions, strategic collaborations, joint ventures, collaborations or capital commitments;

actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;

fluctuations in the valuation of companies perceived by investors to be comparable to us;

• market conditions in the pharmaceutical and biotechnology sector;

•

•

•

•

•

•

•

changes in the structure of healthcare payment systems;

changes or expected changes to government and such implications for the health care industry;

share price and volume fluctuations attributable to inconsistent trading volume levels of our shares;

announcement or expectation of additional financing efforts;

sales of our common stock by us, our insiders or our other stockholders;

expiration of market stand-off or lock-up agreements; and

general economic, industry and market conditions.

The realization of any of the above risks or any of a broad range of other risks, including those described in this “Risk Factors” section, could have a

dramatic and adverse impact on the market price of our common stock.

70

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

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market
that  the  holders  of  a  large  number  of  shares  intend  to  sell  shares,  could  reduce  the  market  price  of  our  common  stock.  As  of  February  21,  2020,  we  had
21,366,950  shares  of  common  stock  outstanding.  Of  these  shares,  approximately  3,278,800  shares  sold  in  our  IPO  may  be  resold  in  the  public  market
immediately without restriction, unless purchased by our affiliates. Of the remaining shares, 17,865,320 shares of our common stock are currently restricted
as a result of securities laws or lock-up agreements, but will be able to be sold in the public market as early as April 28, 2020, which is 180 days following the
date  of  our  final  prospectus  filed  with  the  SEC  on  October  31,  2019  pursuant  to  Rule  424(b)  under  the  Securities  Act  of  1933,  as  amended,  as  further
described below. Moreover, holders of an aggregate of 14,193,281 shares of our common stock have rights, subject to certain conditions, to require us to file
registration  statements  covering  their  shares  or  to  include  their  shares  in  registration  statements  that  we  may  file  for  ourselves  or  other  stockholders.  In
addition,  on  October  31,  2019,  we  filed  a  registration  statement  on  Form  S-8  registering  5,822,484  shares  of  common  stock  that  we  may  issue  under  our
equity  incentive  plans.  As  a  result,  shares  registered  under  this  registration  statement  on  Form  S-8  can  be  freely  sold  in  the  public  market  subject  to  the
satisfaction of vesting arrangements and the exercise of such options, volume limitations applicable to affiliates and the lock-up agreements described below.

We and our executive officers, directors and the holders of substantially all of our common stock have entered into market stand-off agreements with us
and lock-up agreements with the underwriters under which they have agreed, subject to specific exceptions, not to sell, directly or indirectly, any shares of
common stock without the permission of J.P. Morgan Securities LLC, Cowen and Company, LLC, and Piper Jaffray & Co. through April 27, 2020. We refer
to  such  period  as  the  lock-up  period.  When  the  lock-up  period  expires,  we  and  our  securityholders  subject  to  a  lock-up  agreement  or  market  stand-off
agreement could sell our shares in the public market, which could cause our stock price to fall. In addition, J.P. Morgan Securities LLC, Cowen and Company,
LLC, and Piper Jaffray & Co. may, in their sole discretion, release all or some portion of the shares subject to lock-up agreements at any time and for any
reason prior to April 28, 2020. Sales of a substantial number of such shares upon expiration of the lock-up and market stand-off agreements, the perception
that such sales may occur, or early release of these agreements, could cause our market price to fall or make it more difficult for you to sell your common
stock at a time and price that you deem appropriate.

Raising  additional  capital  may  cause  dilution  to  our  existing  stockholders,  restrict  our  operations  or  require  us  to  relinquish  rights  to  our  product
candidates on unfavorable terms to us.

We may seek additional capital through a variety of means, including through public or private equity, debt financings or other sources, including up-
front payments and milestone payments from strategic collaborations. To the extent that we raise additional capital through the sale of equity or convertible
debt or equity securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights
as a stockholder. Such financing may result in dilution to stockholders, imposition of debt covenants, increased fixed payment obligations or other restrictions
that may affect our business. If we raise additional funds through up-front payments or milestone payments pursuant to strategic collaborations with third
parties, we may have to relinquish valuable rights to our product candidates or grant licenses on terms that are not favorable to us. In addition, we may seek
additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating
plans.

Our principal stockholders and management own a significant percentage of our stock and will be able to exert significant control over matters subject to
stockholder approval.

As of December 31, 2019, our executive officers, directors, holders of 5% or more of our capital stock and their respective affiliates beneficially owned
approximately 72% of our voting stock. As a result, this group of stockholders will have the ability to control all matters requiring stockholder approval. For
example, these stockholders may be able to control elections of directors, amendments of our organizational documents or approval of any merger, sale of
assets or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our common stock that you may
feel are in your best interest as one of our stockholders. The interests of this group of stockholders may not always coincide with your interests or the interests
of  other  stockholders  and  they  may  act  in  a  manner  that  advances  their  best  interests  and  not  necessarily  those  of  other  stockholders,  including  seeking  a
premium value for their common stock, and might affect the prevailing market price for our common stock.

We are an “emerging growth company,” and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will
make our common stock less attractive to investors.

71

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (JOBS Act). For as long as we continue to be an
emerging growth company, we intend to take advantage of exemptions from various reporting requirements that are applicable to other public companies that
are not emerging growth companies, including:

•

•

•

•

•

being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, with
correspondingly  reduced  “Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations”  disclosure  in  our  periodic
reports;

not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act;

not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory
audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;

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

exemptions from the requirements of holding nonbinding advisory stockholder votes on executive compensation and stockholder approval of any
golden parachute payments not previously approved.

We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common

stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

We will remain an emerging growth company until the earliest to occur of: (1) the last day of the fiscal year in which we have more than $1.07 billion in
annual revenue; (2) the date we qualify as a “large accelerated filer,” with at least $700 million of equity securities held by non-affiliates; (3) the date on
which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period; and (4) the last day of the fiscal year ending
after the fifth anniversary of our initial public offering.

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply
to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, will be
subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. As a result, changes in rules of
U.S. generally accepted accounting principles or their interpretation, the adoption of new guidance or the application of existing guidance to changes in our
business could significantly affect our financial position and results of operations.

We have identified material weaknesses in our internal control over financial reporting and, if our remediation of the material weaknesses is not effected
in a timely manner or it is not effective or if we identify additional material weaknesses in the future, we may not be able to accurately or timely report our
financial results, or prevent fraud, and investor confidence in our company and the market price of our shares may be adversely affected.

As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in such internal control.
Section  404  of  the  Sarbanes-Oxley  Act  of  2002,  as  amended  (the  Sarbanes-Oxley  Act),  requires  that  we  evaluate  and  determine  the  effectiveness  of  our
internal control over financial reporting. 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 financial statements will not be prevented or detected on a timely basis.

During 2019, in connection with the audits of our financial statements as of and for the years ended December 31, 2018 and 2017, we identified two

material weaknesses in our control over financial reporting.

First, we did not design or maintain an effective control environment commensurate with our financial reporting requirements. Specifically, we lack a
sufficient number of professionals with an appropriate level of accounting knowledge, training and experience to appropriately analyze, record and disclose
accounting  matters  timely  and  accurately.  This  material  weakness  contributed  to  an  additional  material  weakness  in  that  we  did  not  design  and  maintain
formal  accounting  policies,  procedures  and  controls  to  achieve  complete,  accurate  and  timely  financial  accounting,  reporting  and  disclosures,  including
controls over the preparation and review of account reconciliations and journal entries.

These material weaknesses resulted in an audit adjustment to decrease operating expenses and accounts payable in the year ended December 31, 2018,

and audit adjustments to the income tax footnote in the year ended December 31, 2019, that were not

72

material. Additionally, each of the above material weaknesses could result in a misstatement of the aforementioned account balances or disclosures that would
result in a material misstatement to the annual or interim financial statements that would not be prevented or detected.

We have started to take some of the following steps to address the internal control deficiencies that contributed to the material weakness:

•

•

•

hiring  of  additional  finance  and  accounting  personnel  with  prior  experience  working  for  finance  departments  of  public  companies  and  technical
accounting experience, supplemented by third-party resources;

documenting and formally assessing our accounting and financial reporting policies and procedures; and

assessing  significant  accounting  transactions  and  other  technical  accounting  and  financial  reporting  issues,  preparing  accounting  memoranda
addressing these issues and maintaining these memoranda in our corporate records.

However, our efforts are still preliminary and our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2019, our
disclosure controls and procedures were not ineffective due to the material weaknesses in our control environment and formal accounting policies.

While  we  believe  that  these  efforts,  including  working  to  formalize  and  implement  our  accounting  policies  and  internal  controls  and  the  related
documentation, will improve our internal control over financial reporting, the implementation of these measures is ongoing and will require validation and
testing  of  the  design  and  operating  effectiveness  of  internal  controls  over  a  sustained  period  of  financial  reporting  cycles.  We  cannot  assure  you  that  the
measures  we  have  taken  to  date,  and  are  continuing  to  implement,  will  be  sufficient  to  remediate  the  material  weaknesses  we  have  identified  or  avoid
potential future material weaknesses. If the steps we take do not correct the material weaknesses in a timely manner, we will be unable to conclude that we
maintain effective internal controls over financial reporting. Accordingly, there could continue to be a reasonable possibility that these deficiencies or others
could  result  in  a  misstatement  of  our  accounts  or  disclosures  that  would  result  in  a  material  misstatement  of  our  financial  statements  that  would  not  be
prevented or detected on a timely basis.

We  will  incur  increased  costs  as  a  result  of  operating  as  a  public  company,  and  our  management  will  be  required  to  devote  substantial  time  to  new
compliance  initiatives  and  corporate  governance  practices.  Additionally,  if  we  fail  to  maintain  proper  and  effective  internal  controls,  our  ability  to
produce accurate financial statements on a timely basis could be impaired.

As a public company, we have incurred and will continue to incur significant legal, accounting and other expenses that we did not incur as a private
company, and these expenses may increase even more after we are no longer an “emerging growth company.” We are subject to the reporting requirements of
the Securities Exchange Act of 1934, as amended (Exchange Act), the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Protection Act, as well
as rules adopted, and to be adopted, by the SEC and Nasdaq. Our management and other personnel have devoted and will continue to devote a substantial
amount of time to these compliance initiatives. Moreover, these rules and regulations have and will continue to substantially increase our legal and financial
compliance costs and to make some activities more time-consuming and costly, which will increase our operating expenses. We cannot accurately predict or
estimate the amount or timing of additional costs we may incur to respond to these requirements. The impact of these requirements could also make it more
difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers.

In addition, as a public company we will be required to incur additional costs and obligations in order to comply with SEC rules that implement Section
404 of the Sarbanes-Oxley Act. Under these rules, beginning with our second annual report on Form 10-K after we become a public company, we will be
required  to  make  a  formal  assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting,  and  once  we  cease  to  be  an  emerging  growth
company,  we  will  be  required  to  include  an  attestation  report  on  internal  control  over  financial  reporting  issued  by  our  independent  registered  public
accounting  firm.  To  achieve  compliance  with  Section  404  within  the  prescribed  period,  we  will  be  engaging  in  a  process  to  document  and  evaluate  our
internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, engage
outside consultants and adopt a detailed work plan to assess and document the adequacy of our internal control over financial reporting, continue steps to
improve control processes as appropriate, validate through testing that controls are designed and operating effectively, and implement a continuous reporting
and improvement process for internal control over financial reporting.

The  rules  governing  the  standards  that  must  be  met  for  management  to  assess  our  internal  control  over  financial  reporting  are  complex  and  require
significant documentation, testing and possible remediation to meet the detailed standards under the rules. During the course of its testing, our management
may identify material weaknesses or deficiencies which may not be remedied in time to meet the deadline imposed by the Sarbanes-Oxley Act. Our internal
control over financial reporting will not prevent or

73

detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the
control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance
that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if we are unable to maintain proper
and effective internal controls, we may not be able to produce timely and accurate financial statements. If that were to happen, the market price of our stock
could decline and we could be subject to sanctions or investigations by the stock exchange on which our common stock is listed, the SEC or other regulatory
authorities.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

We are subject to the periodic reporting requirements of the Exchange Act. We have designed our disclosure controls and procedures to reasonably assure
that  information  we  must  disclose  in  reports  we  file  or  submit  under  the  Exchange  Act  is  accumulated  and  communicated  to  management,  and  recorded,
processed,  summarized  and  reported  within  the  time  periods  specified  in  the  rules  and  forms  of  the  SEC.  We  believe  that  any  disclosure  controls  and
procedures  or  internal  controls  and  procedures,  no  matter  how  well-conceived  and  operated,  can  provide  only  reasonable,  not  absolute,  assurance  that  the
objectives of the control system are met.

These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or
mistake.  Additionally,  controls  can  be  circumvented  by  the  individual  acts  of  some  persons,  by  collusion  of  two  or  more  people  or  by  an  unauthorized
override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be
detected.

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 currently anticipate that we will retain future earnings for the development,
operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to stockholders
will therefore be limited to any appreciation in the value of their stock.

Provisions in our restated certificate of incorporation and restated bylaws and Delaware law might discourage, delay or prevent a change in control of
our company or changes in our management and, therefore, depress the market price of our common stock.

Our restated certificate of incorporation and restated bylaws contain provisions that could depress the market price of our common stock by acting to
discourage,  delay  or  prevent  a  change  in  control  of  our  company  or  changes  in  our  management  that  the  stockholders  of  our  company  may  deem
advantageous. These provisions, among other things:

•

•

•

•

•

•

•

•

•

establish a classified board of directors so that not all members of our board are elected at one time;

permit only the board of directors to establish the number of directors and fill vacancies on the board;

provide that directors may only be removed “for cause” and only with the approval of two-thirds of our stockholders;

authorize the issuance of “blank check” preferred stock that our board could use to implement a stockholder rights plan (also known as a poison pill);

eliminate the ability of our stockholders to call special meetings of stockholders;

prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;

prohibit cumulative voting;

authorize our board of directors to amend the bylaws;

establish advance notice requirements for nominations for election to our board or for proposing matters that can be acted upon by stockholders at
annual stockholder meetings; and

74

•

require a super-majority vote of stockholders to amend some provisions described above.

In addition, Section 203 of the General Corporation Law of the State of Delaware (DGCL) prohibits a publicly-held Delaware corporation from engaging
in a business combination with an interested stockholder, generally a person which together with its affiliates owns, or within the last three years has owned,
15% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business
combination is approved in a prescribed manner.

Any provision of our amended and restated certificate of incorporation, amended and restated bylaws or Delaware law that has the effect of delaying or
preventing a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our capital stock and could also affect
the price that some investors are willing to pay for our common stock.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes
between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors,
officers or employees.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for:

•

•

•

•

any derivative action or proceeding brought on our behalf;

any action asserting a claim of breach of fiduciary duty;

any action asserting a claim against us arising under the DGCL, our amended and restated certificate of incorporation or our amended and restated
bylaws; and

any action asserting a claim against us that is governed by the internal-affairs doctrine.

This exclusive-forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our
directors,  officers  or  other  employees,  which  may  discourage  lawsuits  against  us  and  our  directors,  officers  and  other  employees.  Any  person  or  entity
purchasing or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and consented to this provision. If a court were to
find  this  exclusive-forum  provision  in  our  amended  and  restated  bylaws  to  be  inapplicable  or  unenforceable  in  an  action,  we  may  incur  additional  costs
associated with resolving the dispute in other jurisdictions, which could seriously harm our business. Nothing in our amended and restated bylaws, including
the exclusive-forum provision, precludes stockholders that assert claims under the Securities Act or the Exchange Act from bringing such claims in state or
federal court, subject to applicable law.

Our  ability  to  use  our  net  operating  loss  carryforwards  and  certain  other  tax  attributes  to  offset  future  taxable  income  may  be  subject  to  certain
limitations.

Our  net  operating  loss  carryforwards  (NOLs)  could  expire  unused  and  be  unavailable  to  offset  future  income  tax  liabilities  because  of  their  limited
duration or because of restrictions under U.S. tax law. Our NOLs generated in tax years ending on or prior to December 31, 2017 are only permitted to be
carried forward for 20 taxable years under applicable U.S. federal tax law. Under the Tax Act, our federal NOLs generated in tax years ending after December
31, 2017 may be carried forward indefinitely, but the deductibility of federal NOLs generated in tax years beginning after December 31, 2017 is limited. It is
uncertain if and to what extent various states will conform to the Tax Act. As of December 31, 2019, we had U.S. federal and state NOLs of $59.1 million,
and $60.7 million, respectively, which will expire beginning in the year 2035.

In  addition,  under  Sections  382  and  383  of  the  Internal  Revenue  Code  of  1986,  as  amended  (the  Code),  if  a  corporation  undergoes  an  “ownership
change” (generally defined as a cumulative change in our ownership by “5-percent stockholders” that exceeds 50 percentage points over a rolling three-year
period), the corporation’s ability to use its pre-change NOLs and certain other pre-change tax attributes to offset its post-change income and taxes may be
limited.  Similar  rules  may  apply  under  state  tax  laws.  We  may  have  experienced  such  ownership  changes  in  the  past,  and  we  may  experience  ownership
changes in the future as a result of shifts in our stock ownership, some of which are outside our control. We have determined that no significant limitation
would be placed on the utilization of our net operating loss and tax credit carryforwards due to prior ownership change. Our ability to utilize those NOLs
could be limited by an “ownership change” as described above and consequently, we may not be able to utilize a material portion of our NOLs and certain
other tax attributes, which could have a material adverse effect on our cash flows and results of operations.

75

We may be subject to securities litigation, which is expensive and could divert management attention.

The market price of our common stock may be volatile and, in the past, companies that have experienced volatility in the market price of their stock have
been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in
substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

Our corporate headquarters are currently located in Princeton, New Jersey, where we lease 12,007 square feet of office space pursuant to an amended
lease agreement that expires on June 30, 2022. In January 2020, we amended our corporate headquarter lease to increase the office space from 8,607 square
feet to 12,007 square feet. We believe that our existing facilities are adequate for our near-term needs, but expect to need additional space as we grow. We
believe that suitable additional or alternative space would be available as required in the future on commercially reasonable terms.

ITEM 3. LEGAL PROCEEDINGS

We are not a party to any material legal proceedings at this time. From time to time, we may be subject to various legal proceedings and claims that arise
in the ordinary course of our business activities. Although the results of litigation and claims cannot be predicted with certainty, we do not believe we are
party to any claim or litigation the outcome of which, if determined adversely to us, would individually or in the aggregate be reasonably expected to have a
material adverse effect on our business, financial condition, results of operations or cash flows. Regardless of the outcome, litigation can have an adverse
impact on us because of defense and settlement costs, diversion of management resources and other factors.

ITEM 4. MINE SAFETY DISCLOSURES

None.

PART II

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF
EQUITY SECURITIES

Our common stock has been listed on the NASDAQ Global Select Market under the symbol “OYST” since October 31, 2019. Prior to this date, there

was no public market for our common stock.

Holders of Common Stock

As of February 21, 2020, there were approximately 80 holders of record of our common stock. The approximate number of holders is based upon the
actual number of holders registered in our records at such date and excludes holders in “street name” or persons, partnerships, associations, corporations, or
other entities identified in security positions listings maintained by depository trust companies.

Dividend Policy

We have never declared or paid any cash dividends on our common stock and do not anticipate paying cash dividends in the foreseeable future.

Recent Sales of Unregistered Securities

During the year ended December 31, 2019, we granted stock options to purchase an aggregate of 1,417,351 shares of common stock to our directors,
officers, employees, consultants and other service providers under our 2016 Equity Incentive Plan (the 2016 Plan) at exercise prices per share ranging from
$5.33 to $14.28. During the same period, we issued and sold to our directors, officers, employees, consultants and other service providers an aggregate of
7,291 shares of common stock upon the exercise of options under our 2016 Plan at an exercise price per share of $1.02, for an aggregate exercise price of
$7,437.

Also during the year ended December 31, 2019, we issued and sold an aggregate of 6,581,590 shares of our Series B preferred stock at a purchase price

of $14.13 per share for aggregate proceeds of $93.0 million.

We believe that the offers, sales and issuances of the securities described above were exempt from registration under the Securities Act under either (1)
Section 4(a)(2) of the Securities Act or Regulation D promulgated thereunder as transactions by an issuer not involving a public offering or (2) Rule 701 in
that the transactions were under compensatory benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of securities in
each of these transactions represented their intention to acquire the securities for investment only and not with view to or for sale in connection with any
distribution thereof and appropriate legends were affixed to the securities issued in these transactions.

Use of Proceeds from Initial Public Offering

On October 30, 2019, the U.S. Securities and Exchange Commission declared effective our registration statement on Form S-1 (File No. 333-234104), as
amended, filed in connection with our initial public offering (“IPO”). The IPO closed on November 4, 2019. In connection with the IPO, we issued and sold
an aggregate of 5,750,000 shares of our common stock, including 750,000 shares sold pursuant to the underwriters’ full exercise of their option to purchase
additional  shares,  at  a  price  to  the  public  of  $16.00  per  share.  The  aggregate  offering  price  for  shares  sold  in  the  offering  was  $92.0  million.  J.P.  Morgan
Securities LLC, Cowen and Company, LLC and Piper Jaffray & Co. acted as the joint book-running managers of the offering. After deducting underwriting
discounts, commissions and offering expenses paid or payable by us, the net proceeds from the IPO were $82.1 million. No offering expenses were paid or
are payable, directly or indirectly, to our directors or officers, to persons owning 10% or more of any class of our equity securities or to any of our affiliates.

There has been no material change in our planned use of the net proceeds from our IPO as described in our final prospectus filed pursuant to Rule

424(b)(4) under the Securities Act with the SEC on October 31, 2019.

Purchases of Equity Securities by the Issuer and Affiliated Purchases

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

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our financial statements
and related notes appearing elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth
elsewhere  in  this  Annual  Report  on  Form  10-K,  including  information  with  respect  to  our  plans  and  strategy  for  our  business,  includes  forward-looking
statements  that  involve  risks  and  uncertainties.  As  a  result  of  many  factors,  including  those  factors  set  forth  in  the  “Risk  Factors”  section  of  this  Annual
Report on Form 10-K, our actual results could differ materially from the results described, in or implied, by these forward-looking statements. Please also see
the section of this Annual Report on Form 10-K titled “Special Note Regarding Forward-Looking Statements.”

Overview

We  are  a  clinical  stage  biopharmaceutical  company  focused  on  the  discovery,  development  and  commercialization  of  first-in-class  pharmaceutical
therapies  to  treat  ocular  surface  diseases.  Our  lead  product  candidate  OC-01  (varenicline),  a  highly  selective  nicotinic  acetylcholine  receptor  (nAChR)
agonist, is being developed as a nasal spray to treat the signs and symptoms of dry eye disease (DED). OC-01’s novel mechanism of action is designed to re-
establish tear film homeostasis by activating the trigeminal parasympathetic pathway and stimulating the glands and cells responsible for natural tear film
production. In our Phase 2b clinical trial (ONSET-1) in 182 subjects, OC-01 demonstrated statistically significant improvements (as compared to placebo) in
both signs and symptoms of DED. Based on OC-01’s clinical trial results and its rapid onset of action, we believe OC-01, if approved, has the potential to
become the new standard of care and redefine how DED is treated for millions of patients. We initiated a

78

Phase  3  clinical  trial  (ONSET-2)  in  July  2019  and  expect  to  report  top-line  results  by  the  end  of  the  second  quarter  2020.  Based  on  the  results  from  this
second registrational trial, we plan to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) in the second half of 2020.
We believe that targeting the parasympathetic nervous system through the use of locally administered cholinergic agonists has the potential to treat a wide
range of diseases and disorders. We have identified several indications, including several outside of ophthalmology, where we believe this approach could
provide a meaningful benefit to patients.

Since our formation in June 2015, we have devoted substantially all of our resources to developing our product candidates. We have incurred significant
operating losses to date. Our net losses were $45.7 million and $16.5 million for the years ended December 31, 2019 and 2018, respectively. As of December
31,  2019,  we  had  an  accumulated  deficit  of  $84.2  million.  We  expect  that  our  operating  expenses  will  increase  significantly  as  we  advance  our  product
candidates through preclinical and clinical development, seek regulatory approval, and prepare for and, if approved, proceed to commercialization; acquire,
discover,  validate  and  develop  additional  product  candidates;  obtain,  maintain,  protect  and  enforce  our  intellectual  property  portfolio;  and  hire  additional
personnel. In addition, we have incurred and will continue to incur additional costs associated with operating as a public company.

We do not have any products approved for sale and have not generated any revenue since inception. Our ability to generate product revenue will depend
on  the  successful  development,  regulatory  approval  and  eventual  commercialization  of  one  or  more  of  our  product  candidates.  Until  such  time  as  we  can
generate significant revenue from product sales, if ever, we expect to finance our operations through private or public equity or debt financings, collaborative
or other arrangements with corporate sources, or through other sources of financing. Adequate funding may not be available to us on acceptable terms, or at
all.  If  we  fail  to  raise  capital  or  enter  into  such  agreements  as  and  when  needed,  we  may  have  to  significantly  delay,  scale  back  or  discontinue  the
development and commercialization of our product candidates.

We  plan  to  continue  to  use  third-party  service  providers,  including  clinical  research  organizations  (CROs)  and  contract  manufacturing  organization
(CMOs),  to  carry  out  our  preclinical  and  clinical  development  and  to  manufacture  and  supply  the  materials  to  be  used  during  the  development  and
commercialization of our product candidates. We do not currently have a sales force. If OC-01 is approved for the treatment of the signs and symptoms of
DED, we intend to deploy a specialty sales force at launch of approximately 150 to 200 field representatives.

Prior to our initial public offering (IPO), we funded our operations primarily from the sale and issuance of redeemable convertible preferred stock and
convertible promissory notes. In February and April 2019, we raised net proceeds of $92.9 million from the sale of Series B redeemable convertible preferred
stock.

In October 2019, we entered into a non-exclusive patent license agreement with Pfizer, pursuant to which we made an upfront payment of $5.0 million. If
we successfully commercialize OC-01, we may be required to pay a single milestone payment in the very low double-digit millions and tiered royalties on net
sales of OC-01 at percentages ranging from the mid-single digits to the mid-teens.

On  November  4,  2019,  we  completed  our  IPO  selling  5,750,000  shares  of  our  common  stock  at  $16.00  per  share.  Proceeds  from  our  IPO,  net  of
underwriting  discounts  and  commissions  and  other  offering  expenses,  were  $82.1  million.  In  connection  with  the  completion  of  our  IPO  on  November  4,
2019, all then outstanding shares of redeemable convertible preferred stock converted into 14,193,281 shares of common stock.

As of December 31, 2019, we had cash and cash equivalents of $139.1 million. We believe that those cash and cash equivalents will be sufficient to fund

our projected operations for at least 12 months from the issuance date of our financial statements as of and for the year ended December 31, 2019.

Components of Operating Results

Revenue

We have not generated any revenue from product sales and do not expect to do so in the near future.

Operating Expenses

Research and Development Expenses

79

Substantially all of our research and development expenses consist of expenses incurred in connection with the development of our product candidates.
These expenses include fees paid to third parties to conduct certain research and development activities on our behalf, consulting costs, costs for laboratory
supplies, product acquisition and license costs, certain payroll and personnel-related expenses, including salaries and bonuses, employee benefit costs and
stock-based  compensation  expenses  for  employees  dedicated  to  our  research  and  product  development  and  allocated  overhead  expenses,  including  rent,
equipment, depreciation, information technology costs and utilities. We expense both internal and external research and development expenses as they are
incurred.

We do not allocate our costs by product candidate, as a significant amount of research and development expenses include internal costs, such as payroll
and other personnel expenses, laboratory supplies and allocated overhead expenses, and external costs, such as fees paid to third parties to conduct research
and development activities on our behalf, are not tracked by product candidate. In particular, with respect to internal costs, several of our departments support
multiple product candidate research and development programs, and therefore the costs cannot be allocated to a particular product candidate or development
program. The following table shows our research and development expenses by type of activity (in thousands):

We  are  focusing  substantially  all  of  our  resources  on  the  development  of  our  product  candidates,  particularly  OC-01.  We  expect  our  research  and
development  expenses  to  increase  substantially  for  at  least  the  next  few  years,  as  we  seek  to  initiate  additional  clinical  trials  for  our  product  candidates,
complete  our  clinical  programs,  pursue  regulatory  approval  of  our  product  candidates  and  prepare  for  the  possible  commercialization  of  these  product
candidates. Predicting the timing or cost to complete our clinical programs or validation of our commercial manufacturing and supply processes is difficult
and  delays  may  occur  because  of  many  factors,  including  factors  outside  of  our  control.  For  example,  if  the  FDA  or  other  regulatory  authorities  were  to
require us to conduct clinical trials beyond those that we currently anticipate, we could be required to expend significant additional financial resources and
time on the completion of clinical development. Furthermore, we are unable to predict when or if our product candidates will receive regulatory approval with
any certainty.

General and Administrative Expenses

General  and  administrative  expenses  consist  principally  of  payroll  and  personnel  expenses,  including  salaries  and  bonuses,  benefits  and  stock-based
compensation  expenses,  professional  fees  for  legal,  consulting,  accounting  and  tax  services,  allocated  overhead  expenses,  including  rent,  equipment,
depreciation, information technology costs and utilities, and other general operating expenses not otherwise classified as research and development expenses.

We  anticipate  that  our  general  and  administrative  expenses  will  increase  as  a  result  of  increased  personnel  costs,  expanded  infrastructure  and  higher
consulting,  legal  and  accounting  services  costs  associated  with  complying  with  the  applicable  stock  exchange  and  Securities  and  Exchange  Commission
(SEC) requirements, investor relations costs and director and officer insurance premiums associated with being a public company.

Interest Income

Interest income consists primarily of interest income earned on our cash and cash equivalents.

Research and development expenses increased by $19.9 million, or 144%, from the year ended December 31, 2018 to the year ended December 31, 2019.
The increase in research and development expenses was primarily due to our advancement of OC-01 and reflected an increase in fees due to CROs and CMOs
of  $12.5  million,  an  increase  of  $5.0  million  related  to  the  license  acquisition  payment  made  to  Pfizer  and  an  increase  in  payroll  and  personnel-related
expenses,  including  salaries  and  bonuses,  benefits  and  stock-based  compensation  expense,  of  $2.4 million.  We  expect  that  our  research  and  development
expenses will continue to increase as we continue to add personnel to support our research and development activities and incur further expenses for CROs
and CMOs in order to continue the advancement of our product candidates.

General and Administrative Expenses

General  and  administrative  expenses  increased  by  $10.7  million,  or  359%,  from  the  year  ended  December  31,  2018  to  the  year  ended  December  31,
2019. The increase in general and administrative expenses was primarily due to the expansion of our organization and reflected an increase in payroll and
personnel-related expenses, including salaries, benefits and stock-based compensation expense, of $4.4 million, an increase in professional services and other
expenses  incurred  in  relation  to  our  IPO  readiness  of  $3.5  million,  an  increase  in  marketing  expenses,  of  $1.5  million,  an  increase  in  facilities  expenses,
consisting primarily of rent and depreciation, of $0.3 million; and an increase in other general and administrative expenses of $1.0 million.

Interest Income

Interest  income  increased  by  $1.4  million,  or  582%,  from  the  year  ended  December  31,  2018  to  the  year  ended  December  31,  2019,  primarily  due  to  an
increase in cash and cash equivalents as a result of the IPO in November 2019 and the sale of Series B redeemable convertible preferred stock in February and
April 2019.

Liquidity and Capital Resources

Sources of Liquidity

Since our formation in 2015 through December 31, 2019, we have funded our operations with an aggregate of $213.4 million in gross cash proceeds from
the sale of redeemable convertible preferred stock and convertible promissory notes and the gross cash proceeds from our IPO. In February and April 2019,
we  received  net  cash  proceeds  of  $84.9  million  and  $8.0  million,  respectively,  from  the  sale  of  Series  B  redeemable  convertible  preferred  stock.  On
November 4, 2019, we received $82.1 million of net proceeds upon completion of our IPO.

As of December 31, 2019, we had cash and cash equivalents of $139.1 million.

Future Funding Requirements

We have incurred net losses since our inception. For the years ended December 31, 2019 and 2018, we had net losses of $45.7 million and $16.5 million,
respectively. As of December 31, 2019, we had an accumulated deficit of $84.2 million. We believe that our existing cash and cash equivalents in the amount
of $139.1 million will be sufficient to fund our projected operations for at least 12 months from the issuance date of our financial statements as of and for the
year ended December 31, 2019.

To date, we have not generated any revenue. We do not expect to generate any meaningful revenue unless and until we obtain regulatory approval of and

commercialize any of our product candidates or enter into collaborative agreements with third parties,

81

 
and we do not know when, or if, either will occur. We expect to continue to incur significant losses for the foreseeable future, and we expect the losses to
increase as we continue the development of, and seek regulatory approvals for, our product candidates and begin to commercialize any approved products. We
are  subject  to  all  of  the  risks  typically  related  to  the  development  of  new  product  candidates,  and  we  may  encounter  unforeseen  expenses,  difficulties,
complications, delays and other unknown factors that may adversely affect our business.

We will continue to require additional capital to develop our product candidates and fund operations for the foreseeable future. We may seek to raise
capital through private or public equity or debt financings, collaborative or other arrangements with corporate sources, or through other sources of financing.
We anticipate that we will need to raise substantial additional capital, the requirements for which will depend on many factors, including: 

•

•

•

•

•

•

•

•

•

•

•

the scope, timing, rate of progress and costs of our drug discovery efforts, preclinical development activities, laboratory testing and clinical trials for
our product candidates;

the number and scope of clinical programs we decide to pursue;

the cost, timing and outcome of preparing for and undergoing regulatory review of our product candidates;

the scope and costs of development and commercial manufacturing activities;

the cost and timing associated with commercializing our product candidates, if they receive marketing approval;

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

the  costs  of  preparing,  filing  and  prosecuting  patent  applications,  maintaining  and  enforcing  our  intellectual  property  rights  and  defending
intellectual property-related claims;

our ability to establish and maintain collaborations on favorable terms, if at all;

our  efforts  to  enhance  operational  systems  and  our  ability  to  attract,  hire  and  retain  qualified  personnel,  including  personnel  to  support  the
development of our product candidates and, ultimately, the sale of our products, following FDA approval;

our implementation of operational, financial and management systems; and

the costs associated with being a public company.

A change in the outcome of any of these or other variables with respect to the development of any of our product candidates could significantly change
the  costs  and  timing  associated  with  the  development  of  that  product  candidate.  Furthermore,  our  operating  plans  may  change  in  the  future,  and  we  will
continue to require additional capital to meet operational needs and capital requirements associated with such operating plans. If we raise additional funds by
issuing equity securities, our stockholders may experience dilution. Any future debt financing into which we enter may impose upon us additional covenants
that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain
investments or engage in certain merger, consolidation or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that
are not favorable to us or our stockholders.

Adequate funding may not be available to us on acceptable terms or at all. Our failure to raise capital as and when needed could have a negative impact
on our financial condition and our ability to pursue our business strategies. If we are unable to raise additional funds when needed, we may be required to
delay, reduce, or terminate some or all of our development programs and clinical trials or we may also be required to sell or license to others rights to our
product  candidates  in  certain  territories  or  indications  that  we  would  prefer  to  develop  and  commercialize  ourselves.  If  we  are  required  to  enter  into
collaborations and other arrangements to supplement our funds, we may have to give up certain rights that limit our ability to develop and commercialize our
product  candidates  or  may  have  other  terms  that  are  not  favorable  to  us  or  our  stockholders,  which  could  materially  affect  our  business  and  financial
condition.

See the section of this Annual Report on 10-K titled “Risk Factors” for additional risks associated with our substantial capital requirements.

(17,083) 

Net cash used in operating activities was $40.8 million for year ended December 31, 2019. Cash used in operating activities was primarily due to the use
of funds in our operations to develop our product candidates resulting in a net loss of $45.7 million, adjusted by non-cash stock-based compensation expense
of  $3.3  million  and  by  a  decrease  in  changes  in  assets  and  liabilities  of  $1.6  million.  Decrease  in  changes  in  assets  and  liabilities  included  an  increase  in
prepaid expenses and other current assets of $2.6 million due to change in prepayments made to CROs and CMOs, offset by an increase in accrued liabilities
of $4.2 million due to an increase in accrued research and development expenses and professional fees.

Net cash used in operating activities was $17.1 million for the year ended December 31, 2018. Cash used in operating activities was primarily due to the
use of funds in our operations to develop our product candidates resulting in a net loss of $16.5 million, increased by a decrease in accrued liabilities of $1.2
million  primarily  due  to  a  decrease  in  accrued  research  and  development  and  accrued  compensation  expenses,  and  partially  offset  decrease  in  prepaid
expenses and other current assets of $0.5 million.

Cash Flows used in Investing Activities

Net cash used in investing activities was $0.2 million for the year ended December 31, 2019, which related to the purchase of property and equipment.

Net cash used in investing activities was zero for the year ended December 31, 2018.

Cash Flows from Financing Activities

Net  cash  provided  by  financing  activities  was  $175.0  million  for  the  year  ended  December  31,  2019, due  to  net  proceeds  from  the  sale  of  Series  B

redeemable convertible preferred stock of $92.9 million and net proceeds from the IPO of $82.1 million.

We did not undertake any financing activities in the year ended December 31, 2018.

2022. The minimum lease payments above do not include any related common area maintenance charges or real estate taxes.

In January 2020 we amended one lease of our office facilities in Princeton, New Jersey to include additional office space, with an expiration date of July

31, 2022. Total future minimum lease payments under this amendment are $0.4 million.

83

We  enter  into  contracts  in  the  normal  course  of  business  with  third-party  contract  organizations  for  preclinical  and  clinical  studies  and  testing,
manufacture  and  supply  of  our  preclinical  materials  and  other  services  and  products  used  for  operating  purposes.  These  contracts  generally  provide  for
termination following a certain period after notice, and therefore we believe that our non-cancelable obligations under these agreements are not material.

In  October  2016,  we  entered  into  an  asset  purchase  agreement  pursuant  to  which  we  acquired  the  compound  OC-02.  Under  this  agreement  we  are
obligated to make milestone payments of up to an aggregate of $37.0 million upon achievement of certain development and regulatory milestone events. In
March 2018, we made a payment of $1.5 million upon completion of the first of these milestones. We accrued such amount as of December 31, 2017 as we
concluded that it was probable that such payment would be made. Under the asset purchase agreement, we are also obligated to make royalty payments at a
mid-single digit percentage rates on net worldwide sales of the covered products. In addition, we are required to pay 15% of any (i) licensing revenue we
receive that is related to OC-02 and (ii) revenue received from the sale of OC-02, up to a maximum aggregate amount of $10.0 million. These commitments
are not included in the table above due to uncertainty of timing of any such payments.

In October 2019, we entered into a non-exclusive patent license agreement (the License Agreement) with Pfizer, which granted us non-exclusive rights
under  Pfizer’s  patent  rights  covering  varenicline  tartrate  to  develop,  manufacture,  and  commercialize  our  OC-01  varenicline  product  candidate.  Under  the
terms of the License Agreement, we made an upfront payment to Pfizer of $5.0 million. If we successfully commercialize OC-01, we may be required to pay
a single milestone payment in the very low double-digit millions and tiered royalties on net sales of OC-01 at percentages ranging from the mid-single digits
to the mid-teens. The royalty obligation to Pfizer will commence upon first commercial sale of OC-01 and will expire upon the later of (a) the expiration of
all regulatory or data exclusivity granted to Pfizer in connection with varenicline in the United States; and (b) the expiration or abandonment of the last valid
claims of the licensed patents. These commitments are not included in the table above due to uncertainty of timing of any such payments.

Critical Accounting Policies, Significant Judgments and Use of Estimates

Our  financial  statements  have  been  prepared  in  accordance  with  U.S.  generally  accepted  accounting  principles,  or  GAAP.  The  preparation  of  these
financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the financial statements and the reported expenses incurred during the reporting periods. Our estimates are based on our historical
experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments
about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different
assumptions  or  conditions.  We  believe  that  the  accounting  policies  discussed  below  are  critical  to  understanding  our  historical  and  future  performance,  as
these policies relate to the more significant areas involving management’s judgments and estimates. For more detail on our critical accounting policies, refer
to Note 1 "Organization and Summary of Significant Accounting Policies" to our audited financial statements included elsewhere in this Annual Report on
Form 10-K.

Accrued Research and Development

We have entered into various agreements with CMOs and CROs. Our research and development accruals are estimated based on the level of services
performed,  progress  of  the  studies,  including  the  phase  or  completion  of  events,  and  contracted  costs.  The  estimated  costs  of  research  and  development
provided, but not yet invoiced, are included in accrued liabilities on the balance sheet. If the actual timing of the performance of services or the level of effort
varies from the original estimates, we will adjust the accrual accordingly. Payments made to CMOs and CROs under these arrangements in advance of the
performance of the related services are recorded as prepaid expenses and other current assets until the services are rendered. To date, our estimated accruals
have not differed materially from the actual costs.

Stock-Based Compensation

We use a fair value-based method to account for all stock-based compensation arrangements with employees and non-employees, including stock options
and stock awards. The fair value of the option granted is recognized on a straight-line basis over the period during which an optionee is required to provide
services in exchange for the option award, known as the requisite service period, which usually is the vesting period. We account for forfeitures as they occur.
In  determining  fair  value  of  the  stock  options  granted,  we  use  the  Black–Scholes  model,  which  requires  the  input  of  subjective  assumptions.  These
assumptions  include:  estimating  the  length  of  time  employees  will  retain  their  vested  stock  options  before  exercising  them  (expected  term),  the  estimated
volatility of our common stock price over the expected term (expected volatility), risk-free interest rate and expected dividends. Changes in the following
assumptions  can  materially  affect  the  estimate  of  fair  value  and  ultimately  how  much  stock-based  compensation  expense  is  recognized;  and  the  resulting
change in fair value, if any, is recognized in our statement of

84

operations and comprehensive loss during the period the related services are rendered. There are several assumptions that are required in the Black Scholes
model.

•

•

•

•

Expected  Term  –  The  expected  term  is  calculated  using  the  simplified  method  which  is  used  when  there  is  insufficient  historical  data  about
exercise  patterns  and  post-vesting  employment  termination  behavior.  The  simplified  method  is  based  on  the  vesting  period  and  the  contractual
term  for  each  grant,  or  for  each  vesting-tranche  for  awards  with  graded  vesting.  The  mid-point  between  the  vesting  date  and  the  maximum
contractual expiration date is used as the expected term under this method. For awards with multiple vesting-tranches, the times from grant until
the mid-points for each of the tranches may be averaged to provide an overall expected term.

Expected Volatility – We use an average historical stock price volatility of a peer group of comparable publicly traded companies in biotechnology
and pharmaceutical related industries to be representative of its expected future stock price volatility, as we do not have any trading history for our
common stock. For purposes of identifying these peer companies, we consider the industry, stage of development, size and financial leverage of
potential comparable companies. For each grant, we measure historical volatility over a period equivalent to the expected term.

Expected Dividend Rate – We have not paid and do not anticipate paying any dividends in the near future. Accordingly, we estimate the dividend
yield to be zero.

Risk-Free Interest Rate – The risk-free interest rate is based on the implied yield currently available on U.S. Treasury zero-coupon issues with a
remaining term equivalent to the expected term of the stock award.

Common Stock Valuations prior to our IPO

Prior to our IPO, the estimated fair value of the common stock underlying our stock options and stock awards was determined at each grant date by our
board of directors, with input from management. All options to purchase shares of our common stock were intended to be exercisable at a price per share not
less than the per-share fair value of our common stock underlying those options on the date of grant.

Prior to the IPO, on each grant date, we developed an estimate of the fair value of our common stock based on the information known to us on the date of
grant,  upon  a  review  of  any  recent  events  and  their  potential  impact  on  the  estimated  fair  value  per  share  of  the  common  stock,  and  valuations  from  an
independent third-party valuation firm.

Prior to the IPO our valuations of our common stock were determined in accordance with the guidelines outlined in the American Institute of Certified

Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation, or the Practice Aid.

The  assumptions  used  to  determine  the  estimated  fair  value  of  our  common  stock  prior  to  the  IPO  were  based  on  numerous  objective  and  subjective

factors, combined with management judgment, including:

•

•

•

•

•

•

•

•

external market conditions affecting the pharmaceutical and biotechnology industry and trends within the industry;

our stage of development and business strategy;

the rights, preferences and privileges of our redeemable convertible preferred stock relative to those of our common stock;

the prices at which we sold shares of our redeemable convertible preferred stock;

our financial condition and operating results, including our levels of available capital resources;

the progress of our research and development efforts;

equity market conditions affecting comparable public companies; and

general U.S. market conditions and the lack of marketability of our common stock.

The Practice Aid identifies various available methods for allocating enterprise value across classes and series of capital stock to determine the estimated

fair value of common stock at each valuation date. In accordance with the Practice Aid, we considered the following methods:

85

•

•

Option Pricing Method. Under the option pricing method, or OPM, shares are valued by creating a series of call options with exercise prices based
on the liquidation preferences and conversion terms of each equity class. The estimated fair values of the preferred and common stock are inferred
by analyzing these

Probability-Weighted Expected Return Method. The probability-weighted expected return method, or PWERM, is a scenario-based analysis that
estimates value per share based on the probability-weighted present value of expected future investment returns, considering each of the possible
outcomes available to us, as well as the economic and control rights of each share class.

Based on our early stage of development and other relevant factors, we determined that OPM method as well as a hybrid approach of the OPM and the
PWERM  methods  were  the  most  appropriate  methods  for  allocating  our  enterprise  value  to  determine  the  estimated  fair  value  of  our  common  stock.  In
valuing the equity prior to the IPO, our board of directors also considered the fact that our stockholders could not freely trade our common stock in the public
markets.  Accordingly,  we  applied  discounts  to  reflect  the  lack  of  marketability  of  our  common  stock  based  on  the  weighted-average  expected  time  to
liquidity.  The  estimated  fair  value  of  our  common  stock  at  each  grant  date  prior  to  our  IPO  reflected  a  non-marketability  discount  partially  based  on  the
anticipated likelihood and timing of a future liquidity event.

Common Stock Valuations following our IPO

Subsequent to the IPO, the fair value of our common stock is based on the closing quoted market price of our common stock as reported by the NASDAQ
Global Select Market on the date of grant.

Income Taxes

We provide for income taxes under the asset and liability method. Current income tax expense or benefit represents the amount of income taxes expected
to  be  payable  or  refundable  for  the  current  year.  Deferred  income  tax  assets  and  liabilities  arise  due  to  differences  between  when  assets  or  liabilities  are
recognized for tax purposes and when they are recognized for financial reporting purposes. Net operating losses and credit carryforwards are also deferred tax
assets. Deferred tax assets and liabilities are measured using the enacted tax rates and laws that will be in effect when such items are expected to reverse.
Deferred income tax assets are reduced, as necessary, by a valuation allowance when management determines it is more likely than not that some or all of the
tax benefits will not be realized.

We  assess  all  material  positions  taken  in  any  income  tax  return,  including  all  significant  uncertain  positions,  in  all  tax  years  that  are  still  subject  to
assessment or challenge by relevant taxing authorities. Assessing an uncertain tax position begins with the initial determination that the position meets the
more-likely-than-not  threshold  and  is  measured  at  the  largest  amount  of  benefit  that  is  greater  than  fifty  percent  likely  of  being  realized  upon  ultimate
settlement.

As of each balance sheet date, unresolved uncertain tax positions must be reassessed, and we will determine whether the factors underlying the more-
likely-than-not threshold assertion have changed and the amount of the recognized tax benefit is still appropriate. The recognition and measurement of tax
benefits requires significant judgment. Judgments concerning the recognition and measurement of a tax benefit might change as new information becomes
available. Our policy is to recognize interest and penalties related to the underpayment of income taxes as a component of income tax expense or benefit. To
date, there have been no interest or penalties charged in relation to the unrecognized tax benefits.

Net operating loss carryforwards and tax credit carryforwards are subject to review and possible adjustment by the Internal Revenue Service and may
become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant stockholders over a three-year period
in excess of 50 percentage points as defined under Sections 382 and 383 in the Internal Revenue Code, which could limit the amount of tax attributes that can
be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on our value immediately prior
to the ownership change. Subsequent ownership changes may further affect the limitation in future years. We have determined that no significant limitation
would be placed on the utilization of our net operating loss and tax credit carryforwards due to prior ownership changes. Subsequent ownership changes may
affect the limitation in future years.

As of December 31, 2019, and 2018, we had unrecognized tax benefits, all of which would affect income tax expense if recognized, before consideration

of our valuation allowance. We do not expect that our uncertain tax positions will materially change in the next 12 months.

86

Off-Balance Sheet Arrangements

Since our inception, we have not engaged in any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Indemnification Agreements

We enter into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless
and  agree  to  reimburse  the  indemnified  parties  for  losses  suffered  or  incurred  by  the  indemnified  party,  including  in  connection  with  any  trade  secret,
copyright,  patent  or  other  intellectual  property  infringement  claim  by  any  third  party  with  respect  to  our  technology.  The  term  of  these  indemnification
agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments we could be required to
make  under  these  arrangements  is  not  determinable.  We  have  never  incurred  costs  to  defend  lawsuits  or  settle  claims  related  to  these  indemnification
agreements. As a result, we believe the fair value of these agreements is minimal.

We  have  also  agreed  to  indemnify  our  directors  and  officers  for  certain  events  or  occurrences  while  the  director  or  officer  is,  or  was  serving,  at  our
request  in  such  capacity.  The  indemnification  period  covers  all  pertinent  events  and  occurrences  during  the  director’s  or  officer’s  service.  The  maximum
potential amount of future payments we could be required to make under these indemnification agreements is not specified in the agreements; however, we
have  director  and  officer  insurance  coverage  that  reduces  our  exposure  and  enables  us  to  recover  a  portion  of  any  future  amounts  paid.  We  believe  the
estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

JOBS Act Accounting Election

The  Jumpstart  Our  Business  Startups  Act  of  2012  (JOBS  Act)  permits  an  “emerging  growth  company”  such  as  us  to  take  advantage  of  an  extended
transition period to comply with new or revised accounting standards applicable to public companies. However, we have chosen to irrevocably “opt out” of
such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such
standards is required for non-emerging growth companies. We intend to rely on other exemptions provided by the JOBS Act, including without limitation, not
being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act.

We will remain an emerging growth company until the earliest to occur of: (1) the last day of our first fiscal year in which we have total annual revenues
of more than $1.07 billion; (2) the date we qualify as a “large accelerated filer,” with at least $700.0 million of equity securities held by non-affiliates; (3) the
date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period; and (4) the last day of the fiscal
year ending after the fifth anniversary of our initial public offering.

Recent Accounting Pronouncements

See the section titled “Organization and Summary of Significant Accounting Policies” in Note 1 to our financial statements included elsewhere in this

Annual Report in the Form 10-K for additional information.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Sensitivity

The market risk inherent in our financial instruments and in our financial position represents the potential loss arising from adverse changes in interest
rates or exchange rates. As of December 31, 2019, we had cash equivalents of $138.1 million, consisting of interest-bearing money market funds for which
the fair value would be affected by changes in the general level of U.S. interest rates. However, due to the short-term maturities and the low-risk profile of our
cash equivalents, an immediate 10% relative change in interest rates would not have a material effect on the fair value of our cash equivalents or on our future
interest income.

We  do  not  believe  that  inflation,  interest  rate  changes  or  foreign  currency  exchange  rate  fluctuations  have  had  a  significant  impact  on  our  results  of

operations for any periods presented herein.

ITEM 9A. CONTROLS AND PROCEDURES

Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures

As of December 31, 2019, management, with the participation of our Chief Executive Officer and Chief Financial Officer, performed an evaluation of the
effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Our
disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is
recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and
communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding
required disclosures.

Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that, as of December 31, 2019, our disclosure controls and
procedures were not effective due to the material weaknesses described below.

Notwithstanding  the  identified  material  weaknesses,  management,  including  our  Chief  Executive  Officer  and  our  Chief  Financial  Officer,  believes  the
financial statements included in this Annual Report on Form 10-K fairly represent in all material respects our financial condition, results of operations and
cash flows at and for the periods presented in accordance with U.S. GAAP.

In designing and evaluating our disclosure controls and procedures, management recognizes that any disclosure controls and procedures, no matter how well
designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and
procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible
controls and procedures relative to their costs.

Material Weaknesses in Internal Control over Financial Reporting

During 2019, in connection with the audits of our financial statements as of and for the years ended December 31, 2018 and 2017, we identified two material
weaknesses  in  our  control  over  financial  reporting.  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 financial statements will not be prevented or detected on a timely basis.

The first material weakness we identified is that we did not design or maintain an effective control environment commensurate with our financial reporting
requirements.  Specifically,  we  lacked  a  sufficient  number  of  professionals  with  an  appropriate  level  of  accounting  knowledge,  training  and  experience  to
appropriately analyze, record and disclose accounting matters timely and accurately. This material weakness contributed to an additional material weakness in
that  we  did  not  design  and  maintain  formal  accounting  policies,  procedures  and  controls  to  achieve  complete,  accurate  and  timely  financial  accounting,
reporting and disclosures, including controls over the preparation and review of account reconciliations and journal entries.

These material weaknesses resulted in an audit adjustment to decrease operating expenses and accounts payable in the year ended December 31, 2018, and
audit  adjustments  to  the  income  tax  footnote  in  the  year  ended  December  31,  2019,  that  were  not  material.  Additionally,  each  of  the  above  material
weaknesses could result in a misstatement of the aforementioned account balances or disclosures that would result in a material misstatement to our annual or
interim financial statements that would not be prevented or detected.

Remediation Plan

We have taken or are in the process of taking the following actions to begin to address the material weaknesses described above:

• we hired a full-time Chief Financial Officer and Controller in July 2019 and October 2019, respectively, and replaced part-time contractors used in

these positions previously;

• we  have  hired  and  are  continuing  to  actively  seek  to  hire  additional  accounting  and  finance  staff  members  to  augment  our  current  staff  and  to

improve the effectiveness of our closing and financial reporting processes;

88

• we  proactively  assessed  significant  accounting  transactions  and  other  technical  accounting  and  financial  reporting  issues,  and  used  technical

accounting consultants to prepare accounting memoranda addressing these issues;

• we  have  strengthened  our  financial  statements  review  procedures  and  the  supervisory  reviews  by  our  management  that  are  performed  during  the

financial close process; and

• we are continuing to formalize and implement our accounting policies and internal controls and the related documentation.

While  we  believe  that  these  efforts  will  improve  our  internal  control  over  financial  reporting,  the  implementation  of  these  measures  is  ongoing  and  will
require validation and testing of the design and operating effectiveness of internal controls over a sustained period of financial reporting cycles.

We believe we are making progress toward achieving the effectiveness of our internal controls and disclosure controls. The actions that we are taking are
subject  to  ongoing  management  review,  as  well  as  audit  committee  oversight.  We  will  not  be  able  to  conclude  whether  the  steps  we  are  taking  will  fully
remediate  these  material  weaknesses  in  our  internal  control  over  financial  reporting  until  we  have  completed  our  remediation  efforts  and  subsequent
evaluation of their effectiveness. We may also conclude that additional measures may be required to remediate the material weaknesses in our internal control
over financial reporting, which may necessitate additional implementation and evaluation time. We will continue to assess the effectiveness of our internal
control over financial reporting and take steps to remediate the known material weaknesses expeditiously.

Changes in Internal Control over Financial Reporting

We are taking actions to remediate the material weaknesses relating to our internal controls over financial reporting, as described above in the remediation
plan. Except as otherwise disclosed herein, there have been no changes in our internal control over financial reporting during year ended December 31, 2019
that have materially affected, or are reasonably likely to materially affect our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Management  recognizes  that  a  control  system,  no  matter  how  well  conceived  and  operated,  can  provide  only  reasonable,  not  absolute,  assurance  that  the
objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of
controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute
assurance that all control issues and instances of fraud or error, if any, have been detected. These inherent limitations include the realities that judgments in
decision  making  can  be  faulty,  and  that  breakdowns  can  occur  because  of  a  simple  error  or  mistake.  Additionally,  controls  can  be  circumvented  by  the
individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is
based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated
goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with
policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur
and not be detected.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Oyster Point Pharma, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  Oyster  Point  Pharma,  Inc.  (the  “Company”)  as  of  December  31,  2019  and  2018,  and  the  related
statements of operations and comprehensive loss, of redeemable convertible preferred stock and stockholders' equity (deficit) and of cash flows for the years
then ended, including the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all
material respects, the financial position of the Company as of December 31, 2019 and 2018, 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.

Basis for Opinion

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

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the
audits to obtain reasonable assurance about whether the 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  financial  statements,  whether  due  to  error  or  fraud,  and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the
financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating
the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Notes to Financial Statements
(in thousands, except share and per share data)

1. Organization and Summary of Significant Accounting Policies

Description of the Business

Oyster Point Pharma, Inc. (the “Company”) was incorporated on June 30, 2015. From inception through December 31, 2019, the Company has been primarily
engaged  in  business  planning,  research,  clinical  development  of  its  lead  therapeutic  product  candidates,  recruiting  and  raising  capital.  The  Company  is  a
clinical stage biopharmaceutical company focused on the discovery, development and commercialization of pharmaceutical therapies to treat ocular surface
diseases. The Company’s principal office is located in Princeton, New Jersey.

Initial Public Offering

On November 4, 2019, the Company completed its initial public offering (IPO) selling 5,750,000 shares of common stock at a price to the public of $16.00
per share. The aggregate net proceeds from the offering, after deducting underwriting discounts and commissions and other offering expenses, were $82.1
million. In addition, upon the closing the IPO, all outstanding shares of redeemable convertible preferred stock outstanding were converted into an aggregate
of 14,193,281 shares of the Company’s common stock.

Liquidity

Since inception, the Company has incurred recurring losses and negative cash flows from operations. The Company incurred net losses of $45.7 million and
$16.5 million for the years ended December 31, 2019 and 2018, respectively, and had an accumulated deficit of $84.2 million as of December 31, 2019. The
Company has historically financed its operations primarily through the sale and issuance of its securities. To date, none of the Company’s product candidates
have been approved for sale and therefore the Company has not generated any revenue from product sales. The Company expects to incur increased sales and
marketing expenses with the commercialization of new and existing products, if approved for sale, as well as increased research and development expenses as
it develops additional product candidates. The Company expects its operating losses to continue to increase for the foreseeable future.

While  the  Company  has  been  able  to  raise  multiple  rounds  of  financing,  there  can  be  no  assurance  that  in  the  event  the  Company  requires  additional
financing, such financing will be available on terms that are favorable, or at all. Failure to generate sufficient cash flows from operations, raise additional
capital or reduce certain discretionary spending would have a material adverse effect on the Company’s ability to achieve its intended business objectives.

The Company had cash and cash equivalents of $139.1 million as of December 31, 2019. Management believes that the Company’s current cash and cash
equivalents will be sufficient to fund its planned operations for at least 12 months from the date of issuance of these financial statements.

Basis of Presentation

The  accompanying  financial  statements  have  been  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States  of  America
(“US GAAP”).

Reverse Stock Split

In  October  2019,  the  Company’s  Board  of  Directors  and  stockholders  approved  an  amendment  to  the  Company’s  amended  and  restated  certificate  of
incorporation to effect a 2.832861-for-1 reverse stock split of the Company’s common stock and redeemable convertible preferred stock, which was effected
on October 18, 2019. The par values of the common stock and redeemable convertible preferred stock were not adjusted as a result of the reverse stock split.
Accordingly, all common stock, redeemable convertible preferred stock, stock options, and related per share amounts as of and for the year ended December
31, 2018 and for the period through October 18, 2019 have been retroactively adjusted to give effect to the reverse stock split.

F-7

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts of
assets  and  liabilities,  disclosure  of  contingent  assets  and  liabilities  and  the  reported  amounts  of  revenue  and  expenses  in  the  financial  statements  and
accompanying notes. On an ongoing basis, management evaluates its estimates, including those related to the valuation of stock awards, income taxes and
certain  research  and  development  accruals  and  for  periods  prior  to  the  IPO,  the  valuation  of  convertible  notes,  derivative  instruments,  and  redeemable
convertible  preferred  stock.  Management  bases  its  estimates  on  historical  experience  and  on  various  other  assumptions  that  are  believed  to  be  reasonable
under  the  circumstances,  the  results  of  which  form  the  basis  for  making  judgments  about  the  carrying  values  of  assets  and  liabilities  that  are  not  readily
apparent from other sources. Actual results could differ from these estimates, and such differences could be material to the Company’s financial position and
results of operations.

Segments

The Company operates and manages its business as one reportable operating segment. The Company’s Chief Executive Officer, who is the chief operating
decision  maker,  reviews  financial  information  on  an  aggregate  basis  for  purposes  of  allocating  resources  and  evaluating  financial  performance.  All  of  the
Company's long-lived assets are located in the United States.

Concentration of Credit Risk

Financial  instruments  that  potentially  subject  the  Company  to  a  concentration  of  credit  risk  consist  of  cash  and  cash  equivalents.  Substantially  all  of  the
Company’s cash is held by one financial institution that management believes is of high credit quality. Such deposits may, at times, exceed federally insured
limits. The Company’s cash equivalents are invested in highly rated money market funds.

Risks and Uncertainties

The Company operates in a dynamic and highly competitive industry and believes that changes in any of the following areas could have a material adverse
effect  on  the  Company’s  future  financial  position,  results  of  operations,  or  cash  flows:  ability  to  obtain  future  financing;  advances  and  trends  in  new
technologies and industry standards; results of clinical trials; regulatory approval and market acceptance of the Company’s products; development of sales
channels; certain strategic relationships; litigation or claims against the Company related to intellectual property, product, regulatory, or other matters; and the
Company’s ability to attract and retain employees necessary to support its growth.

Product candidates developed by the Company will require approvals from the U.S. Food and Drug Administration or other international regulatory agencies
prior to commercial sales. There can be no assurance that the product candidates will receive the necessary approvals. If the Company is denied approval,
approval is delayed or the Company is unable to maintain approval, it could have a materially adverse impact on the Company.

The  Company  has  expended  and  will  continue  to  expend  substantial  funds  to  complete  the  research,  development  and  clinical  testing  of  its  product
candidates. The Company also will be required to expend additional funds to establish commercial-scale manufacturing arrangements and to provide for the
marketing  and  distribution  of  products  that  receive  regulatory  approval.  The  Company  will  require  additional  funds  to  commercialize  its  products.  The
Company is unable to entirely fund these efforts with its current financial resources. If adequate funds are unavailable on a timely basis from operations or
additional sources of financing, the Company may have to delay, reduce the scope of or eliminate one or more of its research or development programs which
would materially and adversely affect its business, financial condition and operations.

The Company relies on single source manufacturers and suppliers for the supply of its product candidates. Disruption from these manufacturers or suppliers
would  have  a  negative  impact  on  the  Company’s  business,  financial  position  and  results  of  operations.  In  addition,  the  Company  is  dependent  upon  the
services of its employees, consultants and other third parties.

Cash and Cash Equivalents

The  Company  considers  all  highly  liquid  investments  purchased  with  an  original  maturity  of  three  months  or  less  at  the  time  of  purchase  to  be  cash
equivalents.  As  of  December  31,  2019  and  2018,  cash  and  cash  equivalents  consisted  of  cash  on  deposit  with  a  bank  denominated  in  U.S.  dollars  and
investment in money market funds.

F-8

Restricted Cash

As  of  December  31,  2019,  the  Company  had  $51,000  of  long-term  restricted  cash  deposited  with  a  financial  institution.  The  entire  amount  is  held  in  a
separate bank account to support a letter of credit agreement related to one of the Company’s office facilities lease, which expires in 2022.

Property and Equipment

Property and equipment is recorded at cost and depreciated using the straight-line method over the estimated useful lives of the related assets as follows:

Office equipment   5 years
Furniture and fixtures  7 years
Leasehold improvements  Shorter of lease term or estimated useful life

Leases

The Company determines if an arrangement is or contains a lease and the classification of that lease at inception of a contract. The Company’s operating lease
asset is included in “operating lease right-of-use asset” (“ROU asset”), and the current and non-current portions of the operating lease liability are included in
“operating lease liability”, and “operating lease liability, non-current”, respectively, on the balance sheets. As of December 31, 2019 and 2018, the Company
had no finance leases.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease
term at the lease commencement date. Operating lease right-of-use assets are based on the corresponding lease liability adjusted for (i) payments made at or
before the commencement date, (ii) initial direct costs incurred, and (iii) tenant incentives under the lease. The Company does not account for renewals or
early terminations unless it is reasonably certain to exercise these options at commencement. Operating lease expense is recognized on a straight-line basis
over the lease term. The Company accounts for lease and non-lease components as a single lease component for operating leases. The Company does not
record leases with terms of 12 months or less on the balance sheets.

As the implicit rate for the operating lease was not determinable, the Company used an incremental borrowing rate based on the information available at the
lease commencement date in determining the present value of future payments. The Company’s incremental borrowing rate was estimated to approximate the
interest  rate  on  a  collateralized  basis  with  similar  terms  and  payments,  in  an  economic  environment  where  the  leased  asset  is  located.  The  Company
determined the incremental borrowing rate by considering various factors, such as its credit rating, interest rates of similar debt instruments of entities with
comparable credit ratings, the lease term and the currency in which the lease was denominated.

Fair Value of Financial Instruments

The carrying amounts for financial instruments consisting of cash and cash equivalents, accounts payable and accrued liabilities approximate fair value due to
their short maturities.

Redeemable Convertible Preferred Stock

The  Company  recorded  all  shares  of  redeemable  convertible  preferred  stock  at  their  respective  fair  values  on  the  dates  of  issuance,  net  of  issuance  costs.
Redeemable  convertible  preferred  stock  was  recorded  outside  of  permanent  equity  because  while  it  was  not  mandatorily  redeemable,  in  certain  events
considered not solely within the Company’s control, such as a merger, acquisition, or sale of all or substantially all of the Company’s assets (each, a “deemed
liquidation  event”),  the  redeemable  convertible  preferred  stock  have  become  redeemable  at  the  option  of  the  holders  of  at  least  a  majority  of  the  then
outstanding  preferred  shares.  The  Company  did  not  adjust  the  carrying  value  of  the  redeemable  convertible  preferred  stock  to  its  liquidation  preference
because a deemed liquidation event obligating the Company to pay the liquidation preference to holders of shares of redeemable convertible preferred stock
was not probable of occurring. All outstanding shares of redeemable convertible preferred stock were converted to common stock shares upon the closing of
the IPO in November 2019.

Research and Development

Research and development expenses consist of compensation costs, employee benefit costs, costs for contract manufacturing organizations (“CMOs”), costs
for clinical research organizations (“CROs”), costs for sponsored research, consulting costs, costs for laboratory supplies, costs for product licenses, facility-
related expenses and depreciation. All research and development costs are charged to research and development expenses within the statements of operations
and comprehensive loss as incurred.

F-9

Payments associated with licensing agreements to acquire exclusive licenses to develop, use, manufacture and commercialize products that have not reached
technological feasibility and do not have alternate commercial use are also expensed as incurred.

The Company’s accruals for research and development activities performed by third parties are estimated based on the level of services performed, progress
of  the  studies,  including  the  phase  or  completion  of  events,  and  contracted  costs.  The  estimated  costs  of  research  and  development  provided,  but  not  yet
invoiced,  are  included  in  accrued  liabilities  on  the  balance  sheet.  If  the  actual  timing  of  the  performance  of  services  or  the  level  of  effort  varies  from  the
original estimates, the Company will adjust the accruals accordingly. Payments made to third parties under these arrangements in advance of the performance
of the related services by the third parties are recorded as prepaid expenses until the services are rendered.

Stock-Based Compensation

The  Company  accounts  for  stock-based  compensation  arrangements  with  employees  and  non-employees  using  a  fair  value  method  which  requires  the
recognition of compensation expense for costs related to all stock-based payments including stock options. The fair value method requires the Company to
estimate  the  fair  value  of  stock-based  payment  awards  on  the  date  of  grant  using  an  option  pricing  model.  The  Company  uses  the  Black-Scholes  pricing
model to estimate the fair value of options granted that are expensed on a straight-line basis over the vesting period. The Company accounts for forfeitures as
they  occur.  Option  valuation  models,  including  the  Black-Scholes  option-pricing  model,  require  the  input  of  several  assumptions,  and  changes  in  the
assumptions used can materially affect the grant-date fair value of an award. These assumptions include the risk-free rate of interest, expected dividend yield,
expected volatility, and the expected life of the award.

Comprehensive Loss

Comprehensive  loss  represents  all  changes  in  stockholders’  equity  (deficit)  except  those  resulting  from  distributions  to  stockholders.  There  have  been  no
items  qualifying  as  other  comprehensive  income  (loss)  and,  therefore,  for  all  periods  presented,  the  Company’s  comprehensive  loss  was  the  same  as  its
reported net loss.

Income Taxes

The  Company  accounts  for  income  taxes  using  the  asset  and  liability  method  whereby  deferred  tax  asset  and  liability  accounts  are  determined  based  on
differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are in effect for the
year in which the differences are expected to affect taxable income. Valuation allowances are established where necessary to reduce deferred tax assets to the
amounts expected to be realized.

The  Company  accounts  for  uncertain  tax  positions  by  assessing  all  material  positions  taken  in  any  assessment  or  challenge  by  relevant  taxing  authorities.
Assessing an uncertain tax position begins with the initial determination of the position’s sustainability and is measured at the largest amount of benefit that is
greater  than  fifty  percent  likely  of  being  realized  upon  ultimate  settlement.  The  Company’s  policy  is  to  recognize  interest  and  penalties  related  to  the
underpayment of income taxes as a component of income tax expense or benefit. The Company recognizes interest and penalties related to unrecognized tax
benefits within the income tax expense line. Accrued interest and penalties are included within the related income tax liability line in the balance sheets. To
date, there have been no interest or penalties charged in relation to the unrecognized tax benefits.

Net Loss per Share Attributable to Common Stockholders

Basic  net  loss  per  common  share  is  calculated  by  dividing  the  net  loss  attributable  to  common  stockholders  by  the  weighted-average  number  of  common
shares outstanding during the period, without consideration of potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss
attributable to common stockholders by the weighted-average number of common shares and potentially dilutive securities outstanding for the period. For
purposes of the diluted net loss per share calculation, the redeemable convertible preferred stock and common stock options are considered to be potentially
dilutive securities. Basic and diluted net loss attributable to common stockholders per share is presented in conformity with the two-class method required for
participating  securities  as  the  redeemable  convertible  preferred  stock  was  a  participating  security.  The  Company’s  participating  securities  did  not  have  a
contractual obligation to share in the Company’s losses. As such, the net loss was attributed entirely to common stockholders. As the Company has reported a
net loss for all periods presented, diluted net loss per common share is the same as basic net loss per common share for those periods.

Recent Accounting Pronouncements

From  time  to  time,  new  accounting  pronouncements  are  issued  by  the  Financial  Accounting  Standards  Board  (the  “FASB”)  under  its  accounting  standard
codifications (“ASC”) or other standard setting bodies and adopted by the Company as of the specified effective date, unless otherwise discussed below.

F-10

Recently adopted accounting pronouncements

In  July  2017,  the  FASB  issued  ASU  No.  2017-11,  Earnings  Per  Share  (Topic  260);  Distinguishing  Liabilities  from  Equity  (Topic  480);  Derivatives  and
Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for
Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope
Exception.  This  ASU  simplifies  the  accounting  for  certain  financial  instruments  with  down  round  features,  a  provision  in  an  equity-linked  financial
instrument  (or  embedded  feature)  that  provides  a  downward  adjustment  of  the  current  exercise  price  based  on  the  price  of  future  equity  offerings.  Down
round features are common in warrants, preferred shares and convertible debt instruments issued by private companies and early-stage public companies. This
update  requires  companies  to  disregard  the  down  round  feature  when  assessing  whether  the  instrument  is  indexed  to  its  own  stock,  for  purposes  of
determining  liability  or  equity  classification.  For  public  business  entities,  this  ASU  is  effective  for  fiscal  years  beginning  after  December  15,  2018,  and
interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The amendments in Part I should be applied
(1) retrospectively to outstanding financial instruments with a down round feature by means of a cumulative-effect adjustment to the balance sheet as of the
beginning  of  the  first  fiscal  year  and  interim  periods;  (2)  retrospectively  to  outstanding  financial  instruments  with  a  down  round  feature  for  each  prior
reporting  period  presented.  The  Company  adopted  this  ASU  effective  January  1,  2019.  The  adoption  of  this  ASU  did  not  have  a  material  effect  on  the
Company’s financial statements and related disclosures.

In February 2018, the FASB issued ASU No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax
Effects  from  Accumulated  Other  Comprehensive  Income.  The  ASU  permits  companies  to  reclassify  disproportionate  tax  effects  in  accumulated  other
comprehensive income (“AOCI”) caused by the Tax Act to retained earnings. For public business entities, this ASU is effective for fiscal years beginning
after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company adopted this ASU effective January 1,
2019. The adoption of this ASU did not have a material effect on the Company’s financial statements and related disclosures.

Recently issued accounting pronouncements not yet adopted

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes, which simplify  various
aspects related to the accounting for income taxes. This ASU removes exceptions to the general principles in Topic 740 related to the approach for intraperiod
tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences.
For  public  companies,  this  ASU  is  effective  for  interim  and  annual  reporting  periods  beginning  after  December  15,  2020.  The  Company  is  currently
evaluating the impact the adoption of this ASU will have on its financial statements and related disclosures.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements
for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements. This ASU removes the requirement to disclose: the
amount  of  and  reasons  for  transfers  between  Level  1  and  Level  2  of  the  fair  value  hierarchy;  the  policy  for  timing  of  transfers  between  levels;  and  the
valuation processes for Level 3 fair value measurements. For public business entities, this ASU is effective for fiscal years beginning after December 15,
2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact the adoption of this ASU
will have on its financial statements and related disclosures.

In  June  2016,  the  FASB  issued  ASU  No.  2016-13,  Financial  Instruments—Credit  Losses  (Topic  326):  Measurement  of  Credit  Losses  on  Financial
Instruments,  which  requires  the  measurement  and  recognition  of  expected  credit  losses  for  financial  assets  held  at  amortized  cost.  This  ASU  replaces  the
existing incurred loss impairment model with an expected loss model. It also eliminates the concept of other-than-temporary impairment and requires credit
losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of
the securities. These changes will result in earlier recognition of credit losses. For SEC filers that are eligible to be smaller reporting companies, this ASU is
effective  for  fiscal  years  beginning  after  December  15,  2022,  and  interim  periods  within  those  fiscal  years.  Early  adoption  is  permitted.  The  Company  is
currently evaluating the impact the adoption of this ASU will have on its financial statements and related disclosures.

2. Fair Value Measurements

The Company assesses the fair value of financial instruments 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.
As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or
liability. As a basis for considering

F-11

such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows:

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

Level 2 Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or

other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

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

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs
to the extent possible as well as considers counterparty credit risk.

As of December 31, 2019, financial assets measured and recognized at fair value were as follows (in thousands):

Money market funds are included in cash and cash equivalents on the balance sheets and are classified within Level 1 of the fair value hierarchy because they
are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency.

There were no financial liabilities measured and recognized at fair value as of December 31, 2019 and December 31, 2018.

In  October  2016,  the  Company  entered  into  an  asset  purchase  agreement  pursuant  to  which  the  Company  acquired  the  compound  OC-02. The  agreement
provides for milestone payments of up to $37.0 million upon achievement of certain milestone events. The agreement also provides for royalty payments in
the  mid-single  digit  percentage  on  covered  product  net  worldwide  sales.  The  Company’s  obligation  to  pay  royalties  will  terminate  at  the  latter  of  patent
expiration in each country or ten years. In addition, the Company is required to pay 15% of any (i) licensing revenue received that is related to OC-02 and
(ii) revenue received from the sale of OC-02, up to a maximum aggregate amount of $10.0 million.

License Agreement

In October 2019, the Company entered into a non-exclusive patent license agreement (the License Agreement) with Pfizer, which granted the Company non-
exclusive  rights  under  Pfizer’s  patent  rights  covering  varenicline  tartrate  to  develop,  manufacture,  and  commercialize  the  OC-01  varenicline  product
candidate. Under the terms of the License Agreement, the Company made an upfront payment to Pfizer of $5.0 million, which is included in research and
development  expense  for  the  year  ended  December  31,  2019.  If  the  Company  successfully  commercializes  OC-01,  it  may  be  required  to  pay  a  single
milestone payment in the very low double-digit millions and tiered royalties on net sales of OC-01 at percentages ranging from the mid-single digits to the
mid-teens. The royalty obligation to Pfizer will commence upon the first commercial sale of OC-01 and will expire upon the later of (a) the expiration of all
regulatory or data exclusivity granted to Pfizer in connection with varenicline in the United States; and (b) the expiration or abandonment of the last valid
claims of the licensed patents.

Operating Lease Obligations

In  January  2018,  the  Company  entered  a  lease  for  office  space  under  a  non-cancelable  operating  lease  with  an  expiration  date  of  March  15,  2020,  in
Princeton, New Jersey. Rent expense is recorded on a straight-line basis over the term of the lease. The total lease payment over the life of the lease is $0.1
million. The remaining lease term was 0.2 years as of December 31, 2019.

In April 2019, the Company entered a lease for office space under a non-cancelable operating lease in Princeton, New Jersey, commencing on July 1, 2019,
for a period of three years from the commencement date. Rent expense is recorded on a straight-line basis over the term of the lease. The total lease payment
over the life of the lease is $0.9 million. The remaining lease term was 2.5 years as of December 31, 2019.
At the commencement date, the Company determined the amounts of the lease liability using a discount rate of 9%, which management determined represents
the Company’s incremental borrowing rate. Lease expense was $0.2 million and less than $0.1 million for the twelve months ended December 31, 2019 and
December 31, 2018, respectively. Cash paid for amounts included in the measurement of the lease liability was $0.2 million and less than $0.1 million for the
twelve months ended December 31, 2019 and December 31, 2018, respectively, and was included in cash flows from operating activities in the statements of
cash flows.

In January 2020 the Company amended the lease of one its office facilities in Princeton, New Jersey to include additional office space, with an expiration date
of July 31, 2022. Total future minimum lease payments under this amendment are $0.4 million.

Contingencies and Indemnifications

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues a
liability  for  such  matters  when  it  is  probable  that  future  expenditures  will  be  made  and  that  such  expenditures  can  be  reasonably  estimated.  Significant
judgment is required to determine both probability and the estimated amount.

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for
general indemnifications, including for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other
intellectual property infringement claim by any third party with respect to its technology. The term of these indemnification agreements is generally perpetual
any time after the execution of the agreement. The Company’s exposure under these agreements is unknown because it involves claims that may be made
against the Company in the future, but that have not yet been made. To date, the Company has not paid any claims or been required to defend

F-14

any action related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations.

The  Company  has  agreed  to  indemnify  its  directors  and  officers  for  certain  events  or  occurrences  while  the  director  or  officer  is,  or  was  serving,  at  the
Company’s request in such capacity. The indemnification period covers all pertinent events and occurrences during the director’s or officer’s service. The
maximum  potential  amount  of  future  payments  the  Company  could  be  required  to  make  under  these  indemnification  agreements  is  not  specified  in  the
agreements; however, the Company has director and officer insurance coverage that reduces its exposure and enables the Company to recover a portion of any
future amounts paid.

6. Income Taxes

The Company did not record a federal or state income tax provision or benefit for the for the years ended December 31, 2019 and December 31, 2018 as it has
incurred net losses since inception. In addition, the net deferred tax assets generated from net operating losses are fully offset by a valuation allowance as the
Company believes it is not more likely than not that the benefit will be realized.

The Company’s loss before provision for income taxes for the years ended December 31, 2019 and 2018 was as follows (in thousands):

Recognition of deferred tax assets is appropriate when realization of such assets is more likely than not. Based upon the weight of available evidence, which
includes  the  Company’s  historical  operating  performance  and  the  U.S.  cumulative  net  losses  in  all  prior  periods,  the  Company  has  provided  a  valuation
allowance against its U.S. deferred tax assets. The Company’s valuation allowance increased by $10.7 million for the year ended December 31, 2019 and by
$4.0 million for the year ended December 31, 2018.

As  of  December  31,  2019,  the  Company  has  U.S.  federal  and  state  net  operating  losses  of  $59.1  million  and  $60.7  million,  respectively,  which  expire
beginning  in  the  year  2035.  As  of  December  31,  2018,  the  Company  had  U.S.  federal  and  state  net  operating  losses  of  $22.8  million  and  $22.9  million,
respectively, which expire beginning in the year 2035.

Utilization of the net operating loss carryforwards may be subject to a substantial annual limitation due to the ownership change limitations provided by the
Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits
before utilization.

A  Section  382  ownership  change  generally  occurs  if  one  or  more  stockholders  or  groups  of  stockholders  who  own  at  least  5%  of  the  Company’s  stock
increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Similar rules may apply
under state tax laws. The Company has experienced an ownership change; however, the change will have no material limit on the Company’s net operating
loss carryforwards. The Company is not in a taxable position and no net operating loss carryforwards have been used to date.

As  of  December  31,  2019  and  2018,  the  Company  also  had  federal  research  and  experimentation  credit  carryforwards  of  $2.1  million  and  $0.6  million,
respectively,  and  state  research  and  experimentation  credit  carryforwards  of  $0.4  and  $0.1  million.  The  federal  research  and  experimentation  credit
carryforwards expire beginning 2037. The California tax credit can be carried forward indefinitely.

As of December 31, 2019 and 2018, the Company had the following unrecognized tax benefits (in thousands):

The reversal of the unrecognized tax benefits would not affect the Company’s effective tax rate to the extent that it continues to maintain a full valuation
allowance against its deferred tax assets. The Company does not expect any changes to uncertain tax benefits within the next twelve months.

The Company recognizes interest and penalties related to income tax matters as a component of income tax expense. No accrued interest and penalties have
been recorded as of December 31, 2019 and 2018.

The Company files income tax returns in the U.S. federal, California and New Jersey jurisdictions. Due to the Company’s net losses, its federal and state
income tax returns are subject to examination for federal and state purposes since inception. As of December 31, 2019, there were no ongoing examinations.

7. Redeemable Convertible Preferred Stock

On  February  15,  2019,  the  Company  executed  the  Series  B  Preferred  Stock  Purchase  Agreement  to  sell  up  to  6,581,590  shares  of  Series  B  redeemable
convertible preferred stock. In February and April 2019, the Company received gross cash proceeds of $85.0 million and $8.0 million, respectively, from the
sale of Series B redeemable convertible preferred stock.

On November 4, 2019, upon the closing of the IPO, all outstanding shares of redeemable convertible preferred stock were converted into an aggregate of
14,193,281 shares of the Company’s common stock and $135.9 million of mezzanine equity was reclassified to common stock and additional paid-in capital.
As of December 31, 2019, there were no shares of redeemable convertible preferred stock issued and outstanding.

8. Common Stock

The  Company  amended  and  restated  its  certificate  of  incorporation,  effective  November  4,  2019,  in  connection  with  the  IPO.  The  amended  and  restated
certificate  of  incorporation  authorizes  the  Company  to  issue  1,000,000,000  shares  of  common  stock,  at  a  par  value  of  $0.001  per  share.  Each  share  of
common stock is entitled to one vote.

The Company reserved common stock shares for future issuance as of December 31, 2019 and 2018 as follows:

Conversion of Series A redeemable convertible preferred stock

Outstanding options under the 2016 Plan

9. Equity Incentive Plans

In 2016, the Company established its 2016 Equity Incentive Plan (the “Plan”) which provides for the granting of stock options to employees and consultants
of the Company. Options granted under the Plan may be either incentive stock options (“ISOs”) or nonqualified stock options (“NSOs”). ISOs may be granted
only to Company employees (including officers and directors who are also employees). NSOs may be granted to Company employees and consultants.

In October 2019, the Company’s Board of Directors and stockholders approved the 2019 Equity Incentive Plan (the 2019 Plan), with an initial shares reserved
of 2,700,000 shares of the Company's common stock plus 99,638 shares reserved but unissued under the 2016 Plan. The 2019 Plan provides for the granting
of stock options, restricted stock, restricted stock units, stock appreciation rights, performance units, and performance shares to the Company's employees,
directors, and others.

The exercise price of an ISO and NSO shall not be less than 100% of the estimated fair value of the shares on the date of grant, as determined by the board of
directors. The exercise price of an ISO granted to a 10% stockholder shall not be less than 110% of the estimated fair value of the shares on the date of grant,
as determined by the board of directors. To date, outstanding options have a term of 10 years and generally vest monthly over a four-year period.

As of December 31, 2019, there were 2,747,047 common stock shares reserved for future grants under the 2019 Plan.

In October 2019, the Company’s Board of Directors and stockholders also approved the 2019 Employee Stock Purchase Plan (the ESPP), which qualifies as
an "employee stock purchase plan" under Section 423 of the Internal Revenue Code, and pursuant to which 270,000 shares of common stock were reserved
for future issuance. The ESPP is designed to enable eligible employees to purchase shares of the Company's common stock at a discount on a periodic basis
through payroll deductions. There were no ESPP purchases during the year ended December 31, 2019.

During the years ended December 31, 2019 and 2018, the Company granted options with a weighted-average grant date fair value of $8.62 and $0.53 per
share, respectively.

The fair value of options that vested during the years ended December 31, 2019 and 2018 was $2.5 million and $0.2 million, respectively.

As of December 31, 2019, the total unrecognized stock-based compensation expense for stock options was $9.4 million, which is expected to be recognized
over a weighted-average period of 3.21 years.

In  October  2019,  the  Company  granted  restricted  stock  units  (RSUs)  for  23,125  common  stock  shares  that  will  vest  one-third  annually  over  three  years,
subject to continuing services to be provided to the Company. Grant date fair value was $16.00 per share, which is the common stock market price at the grant
date. As of December 31, 2019, the total unrecognized stock-based compensation expense for RSUs was $0.3 million, which is expected to be recognized
over a weighted-average period of 2.83 years.

Prior to the IPO, the fair value of the Company’s common stock underlying the stock options was determined by the Board of Directors with assistance from
management and, in part, on input from an independent third-party valuation firm. The Board of Directors determined the fair value of common stock by
considering a number of objective and subjective factors, including valuations of comparable companies, sales of convertible preferred stock, operating and
financial performance, the lack of liquidity of the Company’s common stock and the general and industry-specific economic outlook. Subsequent to the IPO,
the fair value of the Company’s common stock is based on the closing quoted market price of its common stock as reported by the NASDAQ Global Select
Market on the date of grant.

In determining fair value of the stock options granted, the Company uses the Black-Scholes model, which requires the input of several assumptions. These
assumptions  include:  estimating  the  length  of  time  employees  will  retain  their  vested  stock  options  before  exercising  them  (expected  term),  the  estimated
volatility of the Company’s common stock price over the expected term (expected volatility), risk-free interest rate and expected dividend rate. Changes in the
following assumptions can materially affect the estimate of fair value and ultimately how much stock-based compensation expense is recognized.

Expected term. The expected term is calculated using the simplified method which is used when there is insufficient historical data about exercise
patterns and post-vesting employment termination behavior. The simplified method is based on the vesting period and the contractual term for each
grant, or for each vesting-tranche for awards with graded vesting. The mid-point between the vesting date and the maximum contractual expiration
date is used as the expected term under this method. For awards with multiple vesting-tranches, the times from grant until the mid-points for each of
the tranches may be averaged to provide an overall expected term.

Expected volatility.  The  Company  used  an  average  historical  stock  price  volatility  of  a  peer  group  of  comparable  publicly  traded  companies  in
biotechnology and pharmaceutical related industries to be representative of its expected future stock price volatility, as the Company did not have
any  trading  history  for  its  common  stock.  For  purposes  of  identifying  these  peer  companies,  the  Company  considered  the  industry,  stage  of
development,  size  and  financial  leverage  of  potential  comparable  companies.  For  each  grant,  the  Company  measured  historical  volatility  over  a
period equivalent to the expected term.

Risk-free  interest  rate.  The  risk-free  interest  rate  is  based  on  the  implied  yield  currently  available  on  U.S.  Treasury  zero-coupon  issues  with  a
remaining term equivalent to the expected term of the stock award.

Expected dividend rate. The Company has not paid and does not anticipate paying any dividends in the near future. Accordingly, the Company has
estimated the dividend yield to be zero.

The fair value of options granted were calculated using the weighted average assumptions set forth below:

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.1

The  following  summary  describes  our  common  stock  and  preferred  stock,  as  well  as  certain  provisions  of  our  amended  and  restated  certificate  of
incorporation  and  amended  and  restated  bylaws.  This  summary  does  not  purport  to  be  complete  and  is  qualified  in  its  entirety  by  the  provisions  of  our
amended and restated certificate of incorporation and amended and restated bylaws, copies of which have been filed as exhibits to this Annual Report on
Form 10-K, as well as to the applicable provisions of the Delaware General Corporation Law.

Authorized Capital Stock

Our authorized capital stock consists of 1,000,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock,

par value $0.001 per share. All outstanding shares of common stock are fully paid and non-assessable.

Common Stock

Our common stock is listed on the Nasdaq Global Select Market under the symbol “OYST.” The transfer agent and registrar for our common stock is
Computershare Trust Company, N.A. The transfer agent and registrar’s address is 250 Royall Street, Canton, MA 02021, and its telephone number is (800)
962-4284.

Voting Rights

Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of

directors.

Dividends

Subject to preferences that may be applicable to any then-outstanding preferred stock, holders of our common stock are entitled to receive dividends,

if any, as may be declared from time to time by our board of directors out of legally available funds.

Liquidation

In  the  event  of  our  liquidation,  dissolution  or  winding  up,  holders  of  our  common  stock  will  be  entitled  to  share  ratably  in  the  net  assets  legally
available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to
the holders of any then-outstanding shares of preferred stock.
Rights and Preferences

Holders of our common stock have no preemptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions
applicable to our common stock. The rights, preferences and privileges of the holders of our common stock are subject to and may be adversely affected by
the rights of the holders of shares of any series of our preferred stock that we may designate in the future.

Preferred Stock

Under the terms of our amended and restated certificate of incorporation, our board of directors is authorized to issue, without any further vote or
action by the stockholders, shares of preferred stock in one or more series and, with respect to each such series, to fix the designations, powers, preferences
and rights, and the qualifications, limitations or restrictions thereof, of any wholly unissued series of Preferred Stock, including, without limitation, authority
to fix by resolution or resolutions the dividend rights, dividend rate, conversion rights, voting rights, rights and terms of redemption (including sinking fund
provisions), redemption price or prices, and

liquidation preferences of any such series, and the number of shares constituting any such series and the designation thereof, or any of the foregoing.

The issuance of shares of preferred stock will affect, and may adversely affect, the rights of holders of common stock. It is not possible to state the
actual effect of the issuance of any shares of preferred stock on the rights of holders of common stock until our board of directors determines the specific
rights attached to that preferred stock. The effects of issuing additional preferred stock could include one or more of the following:

•
•
•
•

restricting dividends on the common stock;
diluting the voting power of the common stock;
impairing the liquidation rights of the common stock; or
delaying or preventing changes in control or management of our Company.
Preferred stock will be fully paid and nonassessable upon issuance.

Registration Rights of Certain Stockholders

Certain of our stockholders have registration rights under an investors’ rights agreement, as amended (the “Investors’ Rights Agreement”), between
us and such stockholders. These stockholders (and certain of their permitted transferees), may request that we file registration statements under the Securities
Act of 1933 and, upon such request and subject to minimum size and other conditions, we will be required to effect any such registration. We are generally
obligated to bear the expenses, other than underwriting discounts and sales commissions, of all of these registrations. This summary does not purport to be
complete and is qualified in its entirety by the provisions of the Investors’ Rights Agreement, a copy of which has been filed as an exhibit to this Annual
Report on Form 10-K.

Effect of Certain Provisions of our Amended and Restated Certificate of Incorporation and Bylaws and the Delaware Anti-Takeover Statute

Some provisions of Delaware law and our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that

could make the following transactions more difficult:

•
•
•

acquisition of us by means of a tender offer;
acquisition of us by means of a proxy contest or otherwise; or
removal of our incumbent officers and directors.

Those provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids and to promote stability

in our management. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors.

Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

Classified Board of Directors

Our amended and restated certificate of incorporation provides that our board of directors is divided into three classes, designated Class I, Class II,
and Class III. Each class contains an equal number of directors, as nearly as possible, consisting of one-third of the total number of directors constituting our
entire board of directors. The directors in each class are elected to serve for a three-year term, one class being elected each year by our stockholders. At each
annual meeting of stockholders, successors to the class of directors whose term expires at that annual meeting will be elected for a three-year term.

Removal of Directors

Our amended and restated certificate of incorporation provides that stockholders may only remove a director for cause by a vote of at least a majority

of the voting power of the issued and outstanding capital stock of our Company entitled to vote in the election of directors.

Director Vacancies

Vacancies  and  newly  created  directorships  on  our  board  of  directors  may  be  filled  only  by  the  affirmative  vote  of  a  majority  of  the  remaining

directors then in office, even though less than a quorum of the board of directors.

No Cumulative Voting

Our amended and restated certificate of incorporation provides that stockholders do not have the right to cumulate votes in the election of directors.

Special Meetings of Stockholders

Our amended and restated certificate of incorporation and amended and restated bylaws provides that, except as otherwise required by law, special
meetings  of  the  stockholders  may  be  called  only  by  an  officer  at  the  request  of  a  majority  of  our  board  of  directors,  by  the  chairperson  of  our  board  of
directors, or by our Chief Executive Officer.

Amending our Certificate of Incorporation and Bylaws

Our amended and restated certificate of incorporation may be amended or altered in any manner provided by the DGCL. Our amended and restated
bylaws may be adopted, amended, altered, or repealed by stockholders only upon approval of at least majority of the voting power of all the then outstanding
shares of the common stock, except for any amendment of certain provisions, including those listed above, which would require the approval of a two-thirds
majority  of  our  then  outstanding  common  stock.  Additionally,  our  amended  and  restated  certificate  of  incorporation  provides  that  our  bylaws  may  be
amended, altered, or repealed by our board of directors.

Authorized but Unissued Shares

Our authorized but unissued shares of common stock and preferred stock are available for future issuances without stockholder approval, except as
required by the listing standards of Nasdaq, and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital,
acquisitions  and  employee  benefit  plans.  The  existence  of  authorized  but  unissued  and  unreserved  common  stock  and  preferred  stock  could  render  more
difficult or discourage an attempt to obtain control of our Company by means of a proxy contest, tender offer, merger or otherwise.

Delaware Anti-Takeover Statute

We are subject to the provisions of Section 203 of the Delaware General Corporation Law regulating corporate takeovers. In general, Section 203
prohibits a publicly-held Delaware corporation from engaging, under certain circumstances, in a business combination with an interested stockholder for a
period of three years following the date the person became an interested stockholder unless:

•

•

•

prior  to  the  date  of  the  transaction,  the  board  of  directors  of  the  corporation  approved  either  the  business  combination  or  the  transaction  which
resulted in the stockholder becoming an interested stockholder;

upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85%
of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock
outstanding, but not for determining the outstanding voting stock owned by the interested stockholder, (i) shares owned by persons who are directors
and also officers, and (ii) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or exchange offer; or

at or subsequent to the date of the transaction, the business combination is approved by the board of directors of the corporation and authorized at an
annual or special meeting of stockholders, and not by

written consent, by the affirmative vote of at least 66-2/3% of the outstanding voting stock which is not owned by the interested stockholder.

Generally,  a  business  combination  includes  a  merger,  asset  or  stock  sale,  or  other  transaction  resulting  in  a  financial  benefit  to  the  interested
stockholder.  An  interested  stockholder  is  a  person  who,  together  with  affiliates  and  associates,  owns  or,  within  three  years  prior  to  the  determination  of
interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock.
