Item 1. Business

Overview

PART I

We  are  a  physician-led  biopharmaceutical  company  focused  on  dermatological  and  immuno-inflammatory

diseases.  We have two commercial products and a diverse pipeline of drug candidates.

Our  first  commercial  product,  ESKATA  (hydrogen  peroxide)  topical  solution,  40%  (w/w),  or  ESKATA,  is  a
proprietary formulation of high-concentration hydrogen peroxide topical solution which was approved by the U.S. Food and
Drug Administration, or FDA, in December 2017 as an office-based prescription treatment for raised seborrheic keratosis, or
SK, a common non-malignant skin tumor.  We launched ESKATA in the United States in May 2018.  We also submitted a
Marketing Authorization Application, or MAA, for ESKATA in select countries in the European Union, Norway and Iceland
in July 2017 using a decentralized procedure.  In February 2019, we received approval from the Swedish Medical Products
Agency to market ESKATA (hydrogen peroxide) cutaneous solution, 685 mg for the treatment in adults of SKs that are not
pedunculated  and  have  up  to  a  maximum  diameter  of  15  millimeters  each.    We  have  also  received  approval  to  market
ESKATA in the United Kingdom, Iceland and Belgium.

In  November  2018,  we  acquired  RHOFADE  (oxymetazoline  hydrochloride)  cream,  1%,  or  RHOFADE,  which
includes an exclusive license to certain intellectual property for RHOFADE, as well as additional intellectual property, from
Allergan  Sales,  LLC,  or  Allergan.    RHOFADE  was  approved  by  the  FDA  in  January  2017  for  the  topical  treatment  of
persistent facial erythema (redness) associated with rosacea in adults. Persistent facial redness is the most common sign of
rosacea in most skin types.

We continue to develop our sales, marketing and product distribution capabilities for ESKATA and RHOFADE in
order to support our commercialization efforts in the United States.  We plan to continue to deploy sales representatives in
approximately  50  territories  in  the  United  States  which  we  believe  will  allow  us  to  reach  the  health  care  providers  in  the
United States with the highest potential for prescribing ESKATA and RHOFADE to their patients.

We are also developing another high-concentration formulation of hydrogen peroxide, A-101 45% Topical Solution,
as a prescription treatment for common warts, also known as verruca vulgaris.  On an annual basis, approximately 2.0 million
people in the United States are diagnosed with common warts.

Additionally,  in  2015,  we  in-licensed  exclusive,  worldwide  rights  from  Rigel  Pharmaceuticals,  Inc.,  or  Rigel,  to
certain inhibitors of the Janus kinase, or JAK, family of enzymes, for specified dermatological conditions, including alopecia
areata, or AA.  AA is an autoimmune dermatologic condition typically characterized by patchy non-scarring hair loss on the
scalp and body.  More severe forms of AA include total scalp hair loss, known as alopecia totalis, or AT, and total hair loss on
the scalp and body, known as alopecia universalis, or AU. We are also developing these JAK inhibitors for the treatment of
vitiligo, androgenetic alopecia, or AGA, also known as male or female pattern baldness, and atopic dermatitis.    

In  2016,  in  connection  with  the  acquisition  of  Vixen  Pharmaceuticals,  Inc.,  or  Vixen,  we  acquired  additional
intellectual property rights for the development and commercialization of certain JAK inhibitors for specified dermatological
conditions.    We  intend  to  continue  to  in-license  or  acquire  additional  drug  candidates  and  technologies  to  build  a  fully
integrated biopharmaceutical company.

In  2017,  we  acquired  Confluence  Life  Sciences,  Inc.  (now  known  as  Aclaris  Life  Sciences,  Inc.),  or
Confluence.  The acquisition of Confluence added small molecule drug discovery and preclinical development capabilities
that  allowed  us  to  bring  early-stage  research  and  development  activities  in-house  that  we  previously  outsourced  to  third
parties.  We intend to leverage the proprietary KINect drug discovery platform to identify potential drug candidates that we
may  develop  independently  or  with  partners.  We  also  acquired  several  preclinical  drug  candidates,  including  additional
topical JAK inhibitors known as soft-JAK inhibitors, inhibitors of the MK-2 signaling pathway and inhibitors of interleukin-
2-inducible  T  cell  kinase,  or  ITK.  Soft-JAK  inhibitors  may  be  topically  applied  and  active  in  the  skin,  but  will  be  rapidly
metabolized and inactivated when they enter the bloodstream, which may result in significantly reduced systemic exposure.
We also earn revenue from Confluence’s provision of contract research services to third parties.

Our  intellectual  property  portfolio  contains  issued  patents  directed  to  methods  of  use  for  high-concentration
hydrogen  peroxide  compositions  of  at  least  23%  or  more  hydrogen  peroxide,  including  ESKATA  and  A-101  45%  Topical
Solution,  issued  patents  directed  to  methods  of  treating  erythema  associated  with  rosacea  by  administering  oxymetazoline
and  pharmaceutical  cream  compositions  of  oxymetazoline,  including  RHOFADE  and  its  approved  use,  and  issued  patents
directed to our JAK inhibitor drug candidates, ATI-501 and ATI-502.

Our Drug Candidates

We  have  utilized  our  experience  to  establish  a  pipeline  of  drug  candidates  in  dermatological  and  immuno-

inflammatory diseases.  Our pipeline of drug candidates is summarized in the table below:

A-101 45% Topical Solution for the Treatment of Common Warts

We are developing A-101 45% Topical Solution for the treatment of common warts.  Although common warts are
generally not harmful and in most cases eventually clear without medical treatment, they may be painful and aesthetically
unattractive and are contagious.  On an annual basis, approximately 2.0 million people in the United States are diagnosed
with  common  warts.  As  with  SK  lesions,  cryosurgery  is  the  most  frequently  used  in-office  treatment  for  common
warts.  Common warts can also be removed with slow-acting, over-the-counter products containing salicylic acid.  We are not
aware of any prescription drugs that have been approved by the FDA for the treatment of common warts. 

We completed a Phase 2 clinical trial, WART-201, in August 2016 evaluating 40% and 45% concentrations of A-101
for the treatment of common warts, in which we observed statistically significant improvements in the mean change in the
PHYSICIAN’S WART ASSESSMENT, or PWA, score and in complete clearance of common warts in subjects treated with
the 45% concentration of A-101 compared to placebo.  The PWA score is a four-point scale of the investigators assessment of
the severity of a target wart at a particular time point. 

In  June  2017,  we  commenced  two  additional  Phase  2  clinical  trials,  WART-202  and  WART-203,  of  A-101  45%
Topical Solution to assess the dose frequency in adult and pediatric subjects with common warts.  Both trials evaluated the
safety and efficacy of A-101 45% Topical Solution as compared to placebo, or vehicle.  The two randomized, double-blind,
vehicle-controlled  trials  were  designed  to  understand  the  effects  of  dose  frequency  and  to  explore  additional  clinical
endpoints that are now being further evaluated in our Phase 3 development program.  We enrolled a total of 316 subjects at
34 investigational centers in the United States across both trials.

Table of Contents

The WART-202 trial evaluated 157 subjects who self-administered either A-101 45% Topical Solution or placebo
once weekly through Day 56, for a total of 8 treatments.  Each subject had between one and four warts at baseline. The trial
achieved its primary endpoint, which was mean change from baseline in the PWA score of the target wart at Day 56 (one
week after the last treatment).  The mean reduction in PWA score at Day 56 on the target warts was 0.77 points in subjects
who received A-101 45% Topical Solution, compared to a reduction of 0.23 points for the target warts that received placebo,
a result that was also statistically significant (p<0.001). 

The WART-203 trial evaluated 159 subjects who self-administered either A-101 45% Topical Solution or placebo
twice weekly through Day 56, for a total of 16 treatments.  Each subject had between one and six warts at baseline.  The
WART-203  trial  achieved  its  primary  endpoint,  which  was  mean  change  from  baseline  in  the  PWA  scale  score  at  Day  56
(Visit 10 or one week after the last treatment).  The mean reduction in PWA score at Day 56 on the target warts was 0.87
points in subjects who received A-101 45% Topical Solution, compared to a reduction of 0.17 points for the target warts that
received placebo, a result that was statistically significant (p<0.001).

In March 2018, we reported final results, which included a 3-month drug-free follow-up phase, from the WART-203
clinical trial.  In addition, in April 2018, we concluded the WART-202 clinical trial, in which we evaluated a different dosing
regimen from the one used in the WART-203 clinical trial.  In both of these clinical trials, subjects treated with A-101 45%
Topical Solution achieved clinically and statistically significant outcomes for the primary and secondary endpoints of each of
the trials.  There were no treatment-related serious adverse events among subjects treated with A-101 45% Topical Solution.

Based on the results from these clinical trials, we held an end of Phase 2 meeting with the FDA.  A twice-weekly
dosing regimen is being evaluated in our two Phase 3 pivotal clinical trials, which we refer to as THWART-1 and THWART-
2, of A-101 45% Topical Solution for the treatment of common warts, which we initiated in September 2018.  We expect
approximately 1,000 patients will be enrolled in these two trials by the end of March 2019. We expect to report data from
both of these trials in the second half of 2019.  In addition, in February 2019, we commenced an open-label safety extension
trial investigating A-101 45% Topical Solution for the treatment of common warts.  If the results of these three ongoing trials
are  positive,  we  expect  to  submit  a  New  Drug  Application,  or  NDA, to  the  FDA  for  A-101  45%  Topical  Solution  for  the
treatment of common warts in the first half of 2020. 

ATI-501 and ATI-502 for the Treatment of AA and Other Dermatological Indications

We  are  developing  our  JAK  inhibitors,  ATI-501  and  ATI-502,  which  we  in-licensed  from  Rigel,  as  potential
treatments for AA and other dermatological indications. AA is an autoimmune dermatologic condition typically characterized
by patchy non-scarring hair loss on the scalp and body.  More severe forms of AA include AT, which is total scalp hair loss,
and AU, which is total hair loss on the scalp and body.  AA is estimated to affect up to 1.8% of people in the United States
and 2.0% of people globally at some point during their lifetime, with two-thirds of affected individuals being 30 years old or
younger at the time of disease onset. Treatment options for the less severe, patchy forms of AA include corticosteroids, either
topically applied or injected directly into the scalp where the bare patches are located, or the induction of an allergic reaction
at  the  site  of  hair  loss  using  a  topical  contact  sensitizing  agent,  an  approach  known  as  topical  immunotherapy.   The  same
treatment options are utilized for the more severe forms of AA, although utilization of these treatment options for the more
severe forms of AA is limited due to limited efficacy, certain side effects, and their impracticality for extensive surface areas.

We are developing ATI-501 as an oral treatment for AA.  We submitted an investigational new drug application, or
IND,  to  the  FDA  for  ATI-501  for  the  treatment  of  AA  in  October  2016.  Since  the  filing  of  the  IND,  we  have  conducted
several  Phase  1  clinical  trials  to  evaluate  the  pharmacokinetic  and  pharmacodynamic,  or  PK/PD,  properties  of  various
formulations of ATI-501.  Based on the results from these clinical trials, we selected an oral suspension and initiated a Phase
2 dose-response clinical trial of ATI-501 for the treatment of AA.

JAK Inhibitors, ITK Inhibitors and MK-2 Inhibitors

In  August  2017,  we  acquired  Confluence.    This  acquisition  added  small  molecule  drug  discovery  and  preclinical
development capabilities that allowed us to bring early-stage research and development activities in-house that we previously
outsourced to third parties.  We also acquired several preclinical drug candidates as part of the acquisition, including soft-
JAK inhibitors, inhibitors of the MK-2 signaling pathway and ITK inhibitors.  We expect to submit an IND to the FDA for
ATI-450, an MK-2 inhibitor, for rheumatoid arthritis in mid-2019. If the IND is allowed by the FDA, we expect to initiate a
Phase 1 and Phase 2 trial in the second half of 2019. We are considering developing ATI-450 for the treatment of rheumatoid
arthritis,  psoriasis,  hidradenitis  suppurativa,  cryopyrin-associated  periodic  syndrome 
(CAPS),  and  pyoderma
gangrenosum.  We expect to submit an IND to the FDA for ATI-1777, a soft-JAK inhibitor, by the end of the first half of
2020.  We  are  considering  developing  ATI-1777  for  the  treatment  of  several  dermatological  conditions,  including  atopic
dermatitis,  vitiligo  and  AA.    We  are  considering  developing  our  ITK  inhibitors  as  a  potential  treatment  for  psoriasis,
inflammatory dermatoses, and inflammatory bowel disease.

Our Commercial Products

ESKATA for the Treatment of Raised Seborrheic Keratosis

ESKATA is the first FDA-approved drug for the treatment of raised SKs.  SK lesions are among the most common
non-malignant  skin  tumors  and  one  of  the  most  frequent  diagnoses  made  by  dermatologists.  SK  lesions  typically  have  a
waxy, scaly, slightly elevated appearance, and multiple lesions are often present.  The lesions can vary in color from light tan
to  dark  brown  or  black  and  typically  appear  on  the  face,  trunk  and  extremities.    Though  the  lesions  are  non-malignant,
patients often elect to have their condition treated by a health care provider, either because the lesions have become inflamed
or  because  the  patient  feels  they  are  cosmetically  unattractive.    SK  lesions  are  usually  treated  by  cryosurgery,
electrodesiccation,  curettage  or  excision.  Each  of  these  methods  may  be  painful  or  can  result  in  pigmentary  changes  or
scarring at the treatment site.

ESKATA in the United States in May 2018.   We submitted an MAA in select countries in the European Union, Norway and
Iceland in July 2017 using a decentralized procedure.  In February 2019, we received approval from the Swedish Medical
Products Agency to market ESKATA (hydrogen peroxide) cutaneous solution, 685 mg for the treatment in adults of SKs that
are not pedunculated and have up to a maximum diameter of 15 millimeters each. We have also received approval to market
ESKATA  in  the  United  Kingdom,  Iceland  and  Belgium.    We  are  seeking  a  commercial  partner  or  partners  to  market  the
medicine  as  an  aesthetic  skin  treatment  in  various  European  countries  with  the  brand  name  ESKATA  in  Finland,  Iceland,
Netherlands, Norway, Portugal, Spain, Sweden, Czech Republic and Belgium, and the brand name ESKERIELE in Austria,
France, Germany, Ireland, Italy, and the United Kingdom.

In April 2018, we entered into an exclusive license agreement with Cipher Pharmaceuticals Inc., or Cipher, for the
rights to obtain regulatory approval of and commercialize A-101 40% Topical Solution, which we market under the brand
name ESKATA in the United States, in Canada for the treatment of SK, or the Cipher License Agreement.  Under the Cipher
License  Agreement,  Cipher  is  responsible  for  obtaining  marketing  approval  in  Canada  for  A-101  40%  Topical
Solution.  Cipher submitted a New Drug Submission for A-101 40% Topical Solution for the treatment of raised SKs, which
was  accepted  for  review  by  Health  Canada  in  December  2018.  We  will  supply  Cipher  with  finished  product,  and,  if
regulatory  approval  is  obtained,  Cipher  will  be  responsible  for  distribution  and  commercialization  of  A-101  40%  Topical
Solution in Canada.  Additionally, Cipher is responsible for all expenses related to regulatory and commercial activities for
A-101 40% Topical Solution in Canada.

RHOFADE for the Treatment of Persistent Facial Erythema (Redness) Associated with Rosacea in Adults

In  November  2018,  we  acquired  from  Allergan  the  worldwide  rights  to  RHOFADE,  which includes an exclusive
license to certain intellectual property for RHOFADE.  RHOFADE is indicated for the topical treatment of persistent facial
erythema (redness) associated with rosacea in adults. Rosacea is a chronic disease characterized by enduring facial redness
and/or  skin  thickening.  Other  signs  of  rosacea  include  facial  flushing,  visible  blood  vessels  (telangiectasia),  blemishes
resembling acne (papules and pustules), and eye irritation. Burning or stinging, swelling (edema), and dry appearance may
accompany these signs. Persistent facial redness is the most common sign of rosacea in most skin types and, according to a
survey of 1,289 patients with rosacea conducted by the National Rosacea Society, affects 71% of patients with rosacea.

RHOFADE was approved by the FDA in January 2017, and it became commercially available in the United States

in May 2017.

Manufacturing and Supply

We do not have any manufacturing facilities.  We rely on third parties for the manufacture of preclinical and clinical
supplies  for  all  of  our  drug  candidates.    We  also  rely  on  third  parties  for  the  commercial  manufacture  of  ESKATA  and
RHOFADE. 

We have entered into an exclusive, ten-year, automatically renewable supply agreement with PeroxyChem LLC, or
PeroxyChem, to provide hydrogen peroxide, the active pharmaceutical ingredient, or API, that can be used in ESKATA for
the treatment of raised SKs and a number of other specified dermatological indications.  The ten-year term commenced on
the date of first commercial sale of ESKATA in the United States. We or PeroxyChem may terminate the supply agreement
with  prior  written  notice  immediately  for  specified  financial  reasons,  after  a  10-business  day  and  60-day  cure  period  for
material monetary and material non-monetary breaches, respectively, and in the event of a force majeure event, that continues
for  90  consecutive  days.  In  addition,  we  may  terminate  the  PeroxyChem  supply  agreement,  with  prior  written  notice,  for
PeroxyChem’s failure to supply API to us for more than 90 cumulative days in a year.

We  have  entered  into  an  exclusive  commercial  supply  agreement  with  James  Alexander  Corporation,  or  James
Alexander, for the manufacture of the finished dosage form of ESKATA.  We must meet a minimum purchase requirement
each year through 2022.  In the event that we do not meet the minimum purchase requirements, James Alexander may, at its
discretion,  convert  the  agreement  into  a  non-exclusive  agreement.   Additionally,  during  the  term  of  the  agreement,  James
Alexander will not manufacture any competitive product, as defined in the agreement. The term of the agreement with James
Alexander  is  five  years  from  the  date  of  the  first  commercial  sale  of  ESKATA  in  the  United  States  and  thereafter  will  be
renewed automatically for one-year periods. Either party may terminate the agreement for any reason upon 180 days prior
written  notice.  In  addition,  either  party  has  the  right  to  immediately  terminate  the  supply  agreement  under  certain
circumstances, including (i) the other party files for bankruptcy, (ii) the other party materially breaches the

9

 
 
 
 
 
 
 
 
 
Table of Contents

supply agreement and such breach is not cured within a specified period and (iii) any required license, permit or certificate
required of the other party to perform its obligations under the supply agreement is not approved or issued or is revoked by
an applicable governmental regulatory authority. 

We  are  also  party  to  a  manufacturing  and  supply  agreement  with  a  third  party  for  the  finished  dosage  form  of

RHOFADE.

Commercialization

We  are  commercializing  ESKATA  and  RHOFADE  ourselves  in  the  United  States,  and  intend  to  establish
partnerships with third parties to commercialize them outside the United States in countries where we have received, or in the
future  may  receive,  approval.    We  are  continuing  to  develop  our  sales,  marketing  and  product  distribution  capabilities  for
ESKATA  and  RHOFADE  in  order  to  support  our  commercialization  efforts  in  the  United  States.    We  plan  to  continue  to
deploy sales representatives in approximately 50 territories in the United States which we believe will allow us to reach the
health  care  providers  in  the  United  States  with  the  highest  potential  for  prescribing  ESKATA  and  RHOFADE  to  their
patients.    Our  sales  force  is  supported  by  sales  and  marketing  management,  internal  sales  and  marketing,  an  advertising
campaign, and commercial product distribution.

We  sell  ESKATA  to  one  wholesaler,  McKesson  Specialty  Care  Distribution,  or  McKesson,  which  in  turn  resells
ESKATA to health care providers.  We have also entered into agreements with two group purchasing organizations, or GPOs,
and may enter into additional agreements with other GPOs and corporate accounts that provide for administrative fees and
discounted pricing in the form of volume-based rebates and chargebacks.  We have no sales of ESKATA in countries outside
of the United States.  We have a no returns policy for ESKATA. 

We believe dermatologists will be inclined to adopt ESKATA to treat their patients with SK lesions not only because
of  its  clinical  profile,  but  also  because  it  may  provide  an  expanded  source  of  revenue  for  their  practices.  Dermatologists
expect declining reimbursements from third-party payors for providing medical services. In addition, a greater portion of the
cost of medical care has been shifted to patients, in the form of higher deductibles and co‑insurance. Collecting from patients
can be difficult and costly for physician practices. We believe many dermatologists are interested in expanding the cash-pay
aesthetic portion of their practices, meaning the portion of procedures that are not medically necessary and not reimbursed by
third-party payors, by treating new aesthetic patients and by offering new services to current aesthetic patients. Though SK
patients typically come into the dermatology practice seeking a medical diagnosis, we believe they often are willing to pay
for removal of SK lesions to improve appearance even after they learn that the lesions are non-malignant, and that removal
may not be reimbursed. In addition, since ESKATA can be administered by non-physician staff, we believe it could provide
incremental practice revenue with minimal time commitment by the dermatologist after the diagnosis is made.

We began commercializing RHOFADE in the United States in December 2018.  We currently rely on Allergan to
distribute  RHOFADE  on  our  behalf  pursuant  to  the  terms  of  a  transition  services  agreement  while  we  develop  our  sales,
marketing  and  distribution  capabilities  to  support  the  commercialization  of  RHOFADE  in  the  United  States.    We  sell
RHOFADE  to  wholesalers  in  the  United  States,  which,  in  turn,  distribute  it  to  pharmacies  that  will  ultimately  fill  patient
prescriptions.    We  may  also  enter  into  arrangements  with  health  care  providers,  pharmacy  benefit  managers,  third-party
payors, and GPOs which provide for government mandated and/or privately negotiated rebates, chargebacks, and discounts,
with respect to the purchase of RHOFADE.  We have no sales of RHOFADE in countries outside of the United States.

It is estimated that 16.0 million people in the United States suffer from rosacea.  Persistent facial redness is the most
common  sign  of  rosacea  in  most  skin  types.  Although  there  are  many  branded  and  generic  oral  and  topical  medications
prescribed to treat the papules and pustules of rosacea, they are not indicated for the treatment of persistent facial redness.

We believe dermatologists tend to be particularly focused on the safety of pharmaceutical products because, while
skin  diseases  can  have  profound  effects  on  patients’  quality  of  life,  few  are  life-threatening.  As  a  result,  we  believe  that
dermatologists, as well as their patients, often prefer to use topical treatments when possible to limit the risk of systemic side
effects. Dermatologists also tend to place a high level of emphasis on products that are easy to use because they often manage
high  volumes  of  patients.  We  believe  this  also  contributes  to  a  general  preference  for  topical  treatments.  Finally,  in  our
experience, dermatologists tend to engage with sales and medical affairs personnel from the pharmaceutical industry

10

 
 
 
 
 
 
 
 
 
Table of Contents

regarding the scientific evidence supporting dermatology products and the challenges experienced by physicians and patients
in the use of these products. Dermatologists often rely on trusted relationships with scientifically oriented, customer-focused
sales representatives who can provide them with the necessary information to support their use of appropriate treatments.

Competition

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong
emphasis  on  proprietary  drugs.  While  we  believe  that  our  knowledge,  experience  and  scientific  resources  provide  us  with
competitive  advantages,  we  face  potential  competition  from  many  different  sources,  including  major  pharmaceutical,
biotechnology  and  specialty  pharmaceutical  companies,  academic  institutions  and  governmental  agencies  and  public  and
private  research  institutions.  Our  products  compete  with,  and  any  drug  candidates  that  are  approved  and  we  successfully
develop  and  commercialize  will  compete  with,  existing  treatments  and  new  treatments  that  may  become  available  in  the
future.

The key competitive factors affecting the success of ESKATA for the treatment of raised SKs, are likely to be its
efficacy,  safety,  non-invasiveness,  pain  profile  and  ability  to  be  administered  by  non-physician  staff.    With  respect  to
ESKATA for the treatment of raised SKs, we are aware of the following companies that have treatments or are developing
treatments  for  SK:  BioLineRx  Ltd.  is  developing  an  over-the-counter  drug  candidate  targeting  multiple  skin  conditions,
including SK; Skincential Sciences, Inc. currently markets a line of cosmetic products targeting skin conditions, including
SK;  Epipharm,  AG  is  developing  a  topical  drug  candidate  targeting  multiple  skin  conditions,  including  SK;  and  Pulse
Biosciences,  Inc.  is  developing  a  device  targeting  multiple  skin  conditions,  including  SK.    We  are  also  aware  of  early
research being conducted with Akt inhibitors as a potential treatment for SK. None of these products have been approved by
the FDA for the treatment of SK in the United States.

With respect to RHOFADE for the treatment of persistent facial erythema (redness) due to rosacea, we are aware of
one other drug that is approved for this indication: MIRVASO (brimonidine) topical gel, 0.33%, which was approved by the
FDA in 2013, and which is currently marketed by Galderma Laboratories, L.P.

With  respect  to  A-101  45%  Topical  Solution  for  the  treatment  of  common  warts,  we  are  aware  of  the  following
companies that have treatments or are developing treatments for common warts: Perrigo Company plc received a CE Mark
approval  for  BL-5010,  which  it  licenses  from  BioLineRx  Ltd.,  as  a  novel  over-the-counter  treatment  for  the  non-surgical
removal of warts in the European Economic Area; and each of Nielsen BioSciences, Inc., Cutanea Lifesciences, Inc., Phio
Pharmaceuticals Corp. and Verrica Pharmaceuticals Inc. is developing a drug candidate for the treatment of common warts.
In addition, other drugs have been used off-label as treatments for common warts. 

With respect to ATI-501 and ATI-502 for the treatment of AA, we anticipate competing with sensitizing agents such
as  diphencyprone,  and  topical,  intralesional  and  systemic  corticosteroids,  which  have  been  found  to  occasionally  reduce
symptoms of AA. Other treatments utilized for patchy AA include anthralin and minoxidil solution. We may also compete
with  companies  developing  chemical  agents  to  be  used  in  topical  immunotherapies,  as  well  as  companies  developing
biologics, immunosuppressive agents, laser therapy, phototherapy, other JAK inhibitors and prostaglandin analogues to treat
AA.

With  respect  to  ATI-502  for  the  treatment  of  vitiligo,  we  are  aware  of  one  other  company,  Incyte  Corporation,

developing a topical JAK inhibitor for the treatment of vitiligo.

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

11

 
 
 
 
 
 
 
 
 
Table of Contents

and retaining qualified scientific and management personnel and establishing clinical trial sites and subject registration for
clinical trials, as well as in acquiring technologies complementary to, or that may be necessary for, our programs.

Intellectual Property

Our success depends in large part upon our ability to obtain and maintain proprietary protection for our products and
drug candidates and to operate without infringing the proprietary rights of others. We seek to avoid the latter by monitoring
patents  and  publications  that  may  affect  our  business,  and  to  the  extent  we  identify  such  developments,  evaluate  and  take
appropriate  courses  of  action.  Our  policy  is  to  protect  our  proprietary  position  by,  among  other  methods,  filing  patent
applications  on  inventions  that  are  important  to  the  development  and  conduct  of  our  business  with  the  U.S.  Patent  and
Trademark Office, or USPTO, and its foreign counterparts.

With respect to ESKATA and A-101 45% Topical Solution, we do not currently rely on licenses to any third party’s
intellectual  property.  We  own  two  U.S.  patents  that  include  claims  that  cover  the  use  of  high-concentration  hydrogen
peroxide of at least 23%, including ESKATA and A-101 45% Topical Solution, for the alleviation of SK and acrochordons.
The patents in Australia, New Zealand and India include claims that cover the use of high-concentration hydrogen peroxide
of at least 23%, including ESKATA and A-101 45% Topical Solution, for the alleviation of various skin conditions including
SK, acrochordons, corns, tags, acne, warts and rosacea. The patents in Germany, the United Kingdom, Mexico and Singapore
include claims that cover the use of high-concentration hydrogen peroxide of at least 23%, including ESKATA and A-101
45% Topical Solution for the alleviation of acrochordons. The issued patents relating to the use of ESKATA and A-101 45%
Topical Solution begin to expire in 2022, subject to any applicable patent term extension that may be available in a particular
country.

We also own three issued U.S. patents and pending U.S., European and other foreign patent applications directed to
various  formulations  comprising  high-concentration  hydrogen  peroxide,  including  ESKATA  and  A-101  45%  Topical
Solution dosing regimens for such formulations, applicators for use with such formulations, and methods of treating various
skin conditions, including SK and common warts, by the topical administration of such formulations.  Our U.S. formulation,
method of use and applicator patents expire in 2035 and any claims that issue from the pending formulation applications will
expire in 2035, subject to any applicable patent term adjustment or extension that may be available in a particular country.  In
addition, we own a U.S. and PCT patent application directed to the use of high-concentration hydrogen peroxide, including
ESKATA and A-101 45% Topical Solution, for the treatment of warts.  We are in the process of filing national applications
from this PCT patent application in Europe and other foreign countries.  Any claims that issue from these applications will
expire in 2037, subject to any applicable patent term adjustment or extension that may be available in a particular country.

With respect to our patent portfolio relating to RHOFADE, we exclusively license from Allergan a family of U.S.
patents and pending applications, including three issued U.S. patents directed to methods of treating erythema associated with
rosacea  by  administering  alpha-1  adrenergic  receptor  agonists,  including  oxymetazoline,  which  cover  the  approved  use  of
RHOFADE,  that  expire  between  2024  and  2028.    We  also  own  issued  U.S.  and  European  patents  and  pending  U.S.  and
European applications, and other foreign country patents and applications directed to pharmaceutical cream compositions of
oxymetazoline, including RHOFADE, that expire, or will expire, in 2031.  We also own an issued U.S. patent and pending
U.S.  and  European  applications,  and  other  foreign  country  applications  directed  to  methods  of  treating  facial  erythema  by
topically  administering  once  or  twice  daily  1%  or  1.5%  oxymetazoline  hydrochloride,  which  cover  the  approved  use  of
RHOFADE,  that  expire,  or  will  expire,  in  2035.   We  also  own  a  family  of  patents  in  the  United  States,  Europe  and  other
foreign  countries  directed  to  methods  of  treating  purpura  by  administering  alpha-1  adrenergic  receptor  agonists,  including
oxymetazoline,  which  expire  in  2028  and  2029  and  a  family  of  patents  and  applications  in  the  United  States,  Europe  and
other  foreign  countries  directed  to  methods  of  treating  erythema  associated  with  rosacea  by  administering  oxymetazoline,
which expire, or will expire, in 2032.  We also exclusively sublicense from Allergan certain patents and applications in the
United  States  and  foreign  countries  owned  by  a  third  party  for  oxymetazoline  for  the  treatment  of  rosacea  or  purpura  by
topical application, which expire in 2024.

With  respect  to  ATI-501  and  ATI-502,  we  exclusively  license  from  Rigel  multiple  families  of  patents  and
applications  relating  to  these  compounds  and  the  uses  thereof  in  the  field  of  dermatology.    In  particular,  we  exclusively
license  patents  and  applications  with  claims  that  specifically  cover  the  composition  of  matter  for  these  compounds  in  the
United  States,  the  European  Union,  and  other  major  foreign  markets.  The  issued  patents  specifically  directed  to  these
compounds  begin  to  expire  in  2030,  subject  to  any  applicable  patent  term  extension  that  may  be  available  in  a  particular
country. We also exclusively license an issued U.S. patent and pending applications in the United States, Australia, Canada,

12

 
 
 
 
 
 
 
Table of Contents

the European Union and Japan with claims that cover the use of these compounds for the treatment of alopecia areata.  The
U.S. patent, and any claims that issue from these applications, expire, or will expire, in 2034, subject to any applicable patent
term  adjustment  or  extension  that  may  be  available  in  a  particular  country.  We  also  licensed  a  family  of  patents  and
applications that relate to ATI-501 and ATI-502 that expire in 2023, subject to any applicable patent term extension that may
be available in a particular country.

We also exclusively license patents and applications from Columbia University relating to the use of JAK inhibitors
to induce hair growth and treat hair loss disorders, including AA and AGA.  In particular, we exclusively license multiple
U.S.  patents  with  claims  directed  to  the  use  of  certain  third-party  JAK  inhibitors  for  the  treatment  of  hair  loss  disorders,
including  AA  and  AGA,  and  inducing  hair  growth,  which  expires  in  2031.    We  also  exclusively  license  patents  and
applications with claims directed to the use of certain JAK1, JAK2 or JAK3 inhibitors for the treatment of hair loss disorders,
including AA and AGA, and inducing hair growth in the U.S., the European Union, Japan and South Korea.  Any claims that
issue from the pending applications begin to expire in 2031, subject to any applicable patent term adjustment or extension
that may be available in a particular country.  In addition, we exclusively license patent applications in the United States and
other  foreign  countries  directed  to  methods  of  inducing  hair  growth  with  JAK1,  JAK2  or  JAK3  inhibitors  as  well  as
biomarkers  for  AA,  which  if  claims  issue,  would  expire  in  2036,  subject  to  any  applicable  patent  term  adjustment  or
extension that may be available in a particular country.

With respect to our inhibitors of the MK-2 signaling pathway, we own one U.S. patent and pending applications in
the European Union and other foreign countries that cover ATI-450, our lead candidate.  The U.S. patent expires in 2034 and
any  claims  that  issue  from  the  pending  applications  expire  in  2034,  subject  to  any  applicable  patent  term  adjustment  or
extension  that  may  be  available  in  a  particular  country.    We  also  own  seven  U.S.  patents  and  pending  foreign  patent
applications directed to other inhibitors of the MK-2 signaling pathway, which expire or will expire between 2031 and 2034,
subject to any applicable patent term adjustment or extension that may be available in a particular country. 

With  respect  to  our  soft-JAK  inhibitors,  we  have  filed  two  U.S.  and  PCT  applications  directed  to  various  novel
inhibitors of JAK1 and/or JAK3 and methods of using the same.  Any claims that may issue would expire in 2038, subject to
any applicable patent term adjustment or extension that may be available in a particular country.

With respect to our ITK inhibitors, we own multiple U.S. patents and pending applications in the United States and
foreign countries directed to novel inhibitors of ITK and methods of using the same.  The patents and pending applications, if
issued, expire between 2035 and 2038, subject to any applicable patent term adjustment or extension that may be available in
a particular country.

We  also  use  other  forms  of  protection,  such  as  trademark,  copyright,  and  trade  secret  protection,  to  protect  our
intellectual  property,  particularly  where  we  do  not  believe  patent  protection  is  appropriate  or  obtainable.  We  aim  to  take
advantage of all of the intellectual property rights that are available to us and believe that this comprehensive approach will
provide us with proprietary positions for our products and drug candidates, where available.

Patents  extend  for  varying  periods  according  to  the  date  of  patent  filing  or  grant  and  the  legal  term  of  patents  in
various  countries  where  patent  protection  is  obtained.  The  actual  protection  afforded  by  a  patent,  which  can  vary  from
country  to  country,  depends  on  the  type  of  patent,  the  scope  of  its  coverage  and  the  availability  of  legal  remedies  in  the
country.  In  most  countries  in  which  we  file,  the  patent  term  is  20  years  from  the  earliest  date  of  filing  a  non-provisional
patent  application.  In  the  United  States,  a  patent  term  may  be  shortened  if  a  patent  is  terminally  disclaimed  over  another
patent or as a result of delays in patent prosecution by the patentee, and a patent’s term may be lengthened by patent term
adjustment,  which  compensates  a  patentee  for  administrative  delays  by  the  USPTO  in  granting  a  patent  or  by  patent  term
extension, which compensates a patentee for delays at the FDA. The patent term of a European patent is 20 years from its
filing date; however, unlike in the United States, the European patent does not grant patent term adjustments. The European
Union does have a compensation program similar to patent term extension called supplementary patent certificate that would
effectively extend patent protection for up to five years.

We also protect our proprietary information by requiring our employees, consultants, contractors and other advisors
to  execute  nondisclosure  and  assignment  of  invention  agreements  upon  commencement  of  their  respective  employment  or
engagement. Agreements with our employees also prevent them from bringing the proprietary rights of third parties to us. In
addition, we also require confidentiality or service agreements from third parties that receive our confidential information or
materials.

Acquisition and License Agreements

Assignment Agreement with the Estate of Mickey Miller and Finder’s Services Agreement with KPT Consulting, LLC

In  August  2012,  we  entered  into  an  assignment  agreement,  or,  as  amended,  the  Assignment  Agreement,  with  the
Estate  of  Mickey  Miller,  or  the  Miller  Estate,  under  which  we  acquired  some  of  the  intellectual  property  rights  covering
ESKATA and A-101 45% Topical Solution.  The assignment of intellectual property rights covers specified know-how, along
with  modifications  of,  improvements  to  and  variations  on  A-101  that  meet  defined  chemical  properties.  Under  this
agreement,  we  have  the  sole  and  exclusive  right,  but  not  the  duty,  to  develop,  obtain  marketing  approval  for  and
commercialize ESKATA and A-101 45% Topical Solution in various countries throughout the world. We are required to use
commercially reasonable efforts to develop and commercialize at least one product for at least one indication in the United
States. In connection with obtaining the assignment of the intellectual property from the Miller Estate, in August 2012 we
also entered into a separate finder’s services agreement, or the Finder’s Services Agreement, with KPT Consulting, LLC. 

Under the terms of the Assignment Agreement and the Finder’s Services Agreement, we made aggregate upfront
payments  of  $0.6  million  in  2012  and  one-time  milestone  payments  of  $0.4  million  in  2013  upon  the  dosing  of  the  first
human subject with ESKATA in our Phase 2 clinical trial. There are no remaining potential milestone payments under the
Assignment Agreement. Under the Finder’s Services Agreement, we made a one-time milestone payment of $0.3 million in
February 2016 upon the dosing of the first human subject with ESKATA in our Phase 3 clinical trial, a one-time milestone
payment of $1.0 million in April 2017 upon the achievement of a specified regulatory milestone, and a one-time milestone
payment of $1.5 million in May 2018 upon the achievement of a specified commercial milestone.  Under the terms of the
Finder’s  Services  Agreement,  we  are  obligated  to  make  an  additional  milestone  payment  of  $3.0  million  upon  the
achievement  of  a  specified  commercial  milestone.    Under  each  of  the  Assignment  Agreement  and  the  Finder’s  Services
Agreement, we are also obligated to pay royalties on sales of ESKATA or related products, at low single-digit percentages of
net  sales,  subject  to  reduction  in  specified  circumstances.  Both  agreements  will  terminate  upon  the  expiration  of  the  last
pending, viable patent claim of the patents acquired under the Assignment Agreement, but no sooner than 15 years from the
effective date of the agreements.

License Agreement with Rigel

In  August  2015,  we  entered  into  an  exclusive,  worldwide  license  and  collaboration  agreement  with  Rigel  for  the
development and commercialization of products containing two specified JAK inhibitors, ATI-501 and ATI-502, or the Rigel
License  Agreement.  Under  this  agreement,  we  intend  to  develop  these  JAK  inhibitors  for  the  treatment  of  AA  and  other
dermatological conditions. We are required to use commercially reasonable efforts to develop and commercialize at least one
product. We paid Rigel an upfront nonrefundable payment of $8.0 million and have agreed to make aggregate payments of up
to $80.0 million upon the achievement of specified pre-commercialization milestones, such as clinical trials and regulatory
approvals. Further, we have agreed to pay up to an additional $10.0 million to Rigel upon the achievement of a second set of
development milestones. With respect to any products we commercialize under the Rigel License Agreement, we will pay
Rigel quarterly tiered royalties on our annual net sales of each product at a high single-digit percentage of annual net sales,
subject to specified reductions, until the date that all of the patent rights for that product have expired, as determined on a
country-by-country and product-by-product basis or, in specified countries under specified circumstances, ten years from the
first commercial sale of such product.

The Rigel License Agreement terminates on the date of expiration of all royalty obligations unless earlier terminated
by either party for a material breach. We may also terminate the Rigel License Agreement without cause at any time upon
advance  written  notice  to  Rigel.  Rigel,  after  consultation  with  us,  will  be  responsible  for  maintaining  and  prosecuting  the
patent rights, and we will have final decision-making authority regarding such patent rights for a product in the United States
and the European Union. To the extent that we jointly develop intellectual property, we will confer and decide which party
will be responsible for filing, prosecuting and maintaining those patent rights. The Rigel License Agreement also establishes
a joint steering committee composed of an equal number of representatives for each party, which will monitor progress of the
development of products.

Stock Purchase Agreement with Vixen Pharmaceuticals, Inc.

In March 2016, we entered into a stock purchase agreement, or the Vixen Agreement, with Vixen and JAK1, LLC,
JAK2,  LLC  and  JAK3,  LLC,  or  together,  the  Selling  Stockholders,  and  Shareholder  Representative  Services  LLC,  as  the
representative of the Selling Stockholders.  Pursuant to the Vixen Agreement, we acquired all shares of Vixen’s capital stock
from the Selling Stockholders, or the Vixen Acquisition.  Following the Vixen Acquisition, Vixen became our wholly-owned
subsidiary.    We  paid  $0.6  million  upfront  and  issued  an  aggregate  of  159,420  shares  of  our  common  stock  to  the  Selling
Stockholders.  We  are  obligated  to  make  annual  payments  of  $0.1  million  through  March  2022,  with  such  amounts  being
creditable against specified future payments that may be paid under the Vixen Agreement.

Under  the  Vixen  Agreement,  we  agreed  to  use  commercially  reasonable  efforts  to  develop  and  commercialize  at
least one product for the treatment of AA in humans and at least one product for the treatment of AGA in humans, in each
case for commercial sale and distribution throughout the United States and such other areas of the world as we determine to
be  commercially  prudent.    In  the  event  we  do  not  comply  with  these  obligations,  we  are  obligated  to  license,  on  a  non-
exclusive basis, certain intellectual property rights related to the products to the Selling Stockholders or their designee, on
terms to be mutually agreed to by the parties, among other rights exercisable by the Selling Stockholders.

Under  the  Vixen  Agreement,  we  are  obligated  to  make  aggregate  payments  of  up  to  $18.0  million  to  the  Selling
Stockholders upon the achievement of specified pre-commercialization milestones for three products in the United States, the
European Union and Japan, and aggregate payments of up to $22.5 million upon the achievement of specified commercial
milestones.  With  respect  to  any  commercialized  products  covered  by  the  Vixen  Agreement,  we  are  obligated  to  pay  low
single-digit royalties on net sales, subject to specified reductions, limitations and other adjustments, until the date that all of
the patent rights for that product have expired, as determined on a country-by-country and product-by-product basis or, in
specified  circumstances,  ten  years  from  the  first  commercial  sale  of  such  product.  If  we  sublicense  any  of  Vixen’s  patent
rights and know-how acquired pursuant to the Vixen Agreement, we will be obligated to pay a portion of any consideration
we receive from such sublicenses in specified circumstances. 

License Agreement with Columbia University 

As a result of the Vixen Acquisition, we became party to the Exclusive License Agreement, by and between Vixen
and  the  Trustees  of  Columbia  University  in  the  City  of  New  York,  or  Columbia,  dated  as  of  December  31,  2015,  or  as
amended,  the  Columbia  License  Agreement.    Pursuant  to  the  Columbia  License  Agreement,  we  have  an  exclusive,
worldwide license under specified Columbia patent rights and a non-exclusive, worldwide license under specified Columbia
know-how  in  all  fields  to  develop  and  commercialize  a  product  that  otherwise  infringes  a  Columbia  patent  right  or  uses
Columbia know-how.  Our rights to this Columbia intellectual property cover the use of specified JAK inhibitor compounds
for the potential treatment of AA, AGA and other dermatological conditions. 

We  are  obligated  to  pay  Columbia  an  annual  license  fee  of  $10,000,  subject  to  specified  adjustments  for  patent
expenses  incurred  by  Columbia  and  creditable  against  any  royalties  that  may  be  paid  under  the  Columbia  License
Agreement. We are also obligated to pay up to an aggregate of $11.6 million upon the achievement of specified commercial
milestones,  including  specified  levels  of  net  sales  of  products  covered  by  Columbia  patent  rights  and/or  know-how,  and
royalties at a sub-single-digit percentage of annual net sales of products covered by Columbia patent rights and/or know-how,
subject to specified adjustments. If we sublicense any of Columbia’s patent rights and know-how acquired pursuant to the
Columbia  License  Agreement,  we  will  be  obligated  to  pay  Columbia  a  portion  of  any  consideration  received  from  such
sublicenses in specified circumstances.  The royalties, as determined on a country-by-country and product-by-product basis,
are payable until the date that all of the patent rights for that product have expired, the expiration of any market exclusivity
period granted by a regulatory body or, in specified circumstances, ten years from the first commercial sale of such product.

We have agreed to use commercially reasonable efforts to develop and commercialize at least one product. In the
event we do not comply with this obligation, Columbia has the option to terminate the license or convert the exclusive patent
license  to  a  non-exclusive  patent  license.  Further,  in  the  event  we  do  not  comply  with  our  obligations  under  the  Vixen
Agreement to develop and commercialize products, our rights under the Columbia License Agreement may revert to a party
to  be  designated  by  the  Selling  Stockholders.    Columbia  is  responsible  for  maintaining  and  prosecuting  the  patent  rights,
giving due consideration to our reasonable comments related thereto.

The Columbia License Agreement terminates on the date of expiration of all royalty obligations thereunder unless
earlier  terminated  by  either  party  for  a  material  breach,  subject  to  a  specified  cure  period.  We  may  also  terminate  the
Columbia License Agreement without cause at any time upon advance written notice to Columbia.

Agreement and Plan of Merger with Confluence

In August 2017, we entered into an Agreement and Plan of Merger, or the Confluence Agreement, with Confluence,
Aclaris Life Sciences, Inc., our wholly-owned subsidiary, or Merger Sub, and Fortis Advisors LLC, as representative of the
equity holders of Confluence.  Pursuant to the terms of the Confluence Agreement, the Merger Sub merged with and into
Confluence,  with  Confluence  surviving  as  our  wholly-owned  subsidiary,  resulting  in  our  acquisition  of  100%  of  the
outstanding shares of Confluence.  We paid $10.3 million in cash and issued 349,527 shares of our common stock with a fair
value of $9.7 million to the Confluence equity holders. 

In November 2018, we achieved a development milestone specified in the Confluence Agreement.  The milestone
payment to the former Confluence equity holders was comprised of $2.5 million in cash and 253,208 shares of our common
stock  with  a  fair  value  of  $2.2  million.   We  also  agreed  to  pay  the  former  Confluence  equity  holders  aggregate  additional
contingent consideration of up to $75.0 million, based upon the achievement of certain regulatory and commercial milestones
set forth in the Confluence Agreement. In addition, we have agreed to pay the former Confluence equity holders specified
future  royalty  payments  calculated  as  a  low  single-digit  percentage  of  annual  net  sales,  subject  to  specified  reductions,
limitations and other adjustments, until the date that all of the patent rights for that product have expired, as determined on a
country-by-country and product-by-product basis or, in specified circumstances, ten years from the first commercial sale of
such product.  In addition, if we sell, license or transfer any of the intellectual property acquired from Confluence to a third
party, we will be obligated to pay the former Confluence equity holders a portion of any incremental consideration (in excess
of the development and milestone payments described above) that we receive from such sale, license or transfer in specified
circumstances. 

Asset Purchase Agreement with Allergan

In November 2018, we closed the acquisition of the worldwide rights to RHOFADE, which includes an exclusive
license to certain intellectual property for RHOFADE, as well as additional intellectual property, from Allergan, pursuant to
the terms of the Asset Purchase Agreement dated as of October 15, 2018, or as amended, the Asset Purchase Agreement.

At  the  closing  of  the  acquisition,  we  paid  total  cash  consideration  of  approximately  $66.1  million,  consisting  of
approximately $59.6 million paid to Allergan and $6.5 million placed in escrow. We have also agreed to pay Allergan a one-
time  payment  of  $5.0  million  upon  the  achievement  of  a  specified  development  milestone  related  to  the  potential
development of an additional dermatology product. In addition, we have agreed to pay Allergan specified royalty payments,
ranging from a mid-single digit percentage to a mid-teen percentage of net sales, subject to specified reductions, limitations
and other adjustments, on a country-by-country basis until the date that the patent rights related to a particular product, such
as  RHOFADE,  have  expired  or,  if  later,  November  30,  2028.  In  addition,  we  have  agreed  to  assume  the  obligation  to  pay
specified royalties and milestone payments under agreements with Aspect Pharmaceuticals, LLC and Vicept Therapeutics,
Inc. Members of our management team, including Neal Walker, Frank Ruffo, Christopher Powala and Stuart Shanler, as well
as  Stephen  Tullman,  the  chairman  of  our  board  of  directors,  are  former  stockholders  of  Vicept  Therapeutics,  Inc.,  and  Dr.
Shanler is also a current member of Aspect Pharmaceuticals, LLC. In their capacities as current or former holders of equity
interests in these entities, these individuals may be entitled to receive a portion of the potential future payments payable by
us.

Government Regulation and Product Approval

Governmental authorities in the United States, at the federal, state and local level, and analogous authorities in other
countries  extensively  regulate,  among  other  things,  the  research,  development,  testing,  manufacture,  safety  surveillance,
efficacy,  quality  control,  labeling,  packaging,  distribution,  record  keeping,  promotion,  storage,  advertising,  distribution,
marketing, sale, export and import, and the reporting of safety and other post-market information of products such as the ones
we are commercializing and developing. A drug candidate must be approved by the FDA before it may be legally promoted
in the United States and by comparable foreign regulatory authorities before marketing in other jurisdictions.  The process of
obtaining regulatory approvals and the subsequent compliance with applicable federal, state, local and foreign statutes and
regulations require the expenditure of substantial time and resources. Failure to comply with the applicable U.S. requirements
at  any  time  during  the  product  development  process,  approval  process  or  after  approval  may  subject  an  applicant  and/or
sponsor  to  a  variety  of  administrative  or  judicial  sanctions,  including  refusal  by  regulatory  authorities  to  approve
applications, withdrawal of an approval, imposition of a clinical hold, import/export delays, issuance of warning letters and
untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines,
refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought
by FDA and the Department of Justice or other governmental entities.

United States Government Regulation

NDA Approval Processes

In  the  United  States,  the  FDA  regulates  drug  and  medical  device  products  under  the  Federal  Food,  Drug,  and
Cosmetic  Act,  or  FDCA,  and  its  implementing  regulations.    A-101  45%  Topical  Solution  is  comprised  of  both  a  drug
component (the hydrogen peroxide solution) and a pen-type applicator. The FDA’s Center for Drug Evaluation and Research
has primary jurisdiction over the premarket development, review and approval of our drug candidates. Accordingly, we are
investigating our drug candidates pursuant to IND applications and expect to seek approval through the NDA pathway. Based
on our discussions with the FDA to date, we do not anticipate that the FDA will require us to submit a separate marketing
application  for  the  pen-type  applicator  that  will  be  used  with  A-101  45%  Topical  Solution  for  the  treatment  of  common
warts, but this could change during the course of the FDA’s review of the NDA.

An  applicant  seeking  approval  to  market  and  distribute  a  new  drug  product  in  the  United  States  must  typically

undertake the following:

·

·
·

·

·
·
·

·
·

completion of preclinical laboratory tests, animal studies and formulation studies in compliance with the FDA’s
good laboratory practice regulations;
submission to the FDA of an IND which must take effect before clinical trials may begin; 
approval by an independent institutional review board, or IRB, representing each clinical site before clinical testing
may be initiated at the clinical site;
performance of adequate and well-controlled clinical trials in accordance with good clinical practice, or GCP,
regulations to establish the safety and efficacy of the proposed drug product for each indication;
preparation and submission to the FDA of an NDA;
review of the NDA by a FDA advisory committee, if applicable;
satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which the
product or its components are produced to assess compliance with current good manufacturing practices, or cGMP,
and regulations to assure that the facilities, methods and controls are adequate to preserve the product’s identity,
strength, quality and purity;
payment of user fees and securing FDA approval of the NDA; and
compliance with any post-approval requirements, including potential requirements for a risk evaluation and
mitigation strategy and post-approval studies required by the FDA.

Once a drug candidate is identified for development, it enters the preclinical or nonclinical testing stage. Preclinical
studies include laboratory evaluations of product chemistry, pharmacology, toxicity and formulation. An IND sponsor must
submit the results of the preclinical studies, together with manufacturing information and analytical data, to the FDA as part
of the IND. Some preclinical studies may continue even after the IND is submitted. In addition to including the results of the
preclinical studies, the IND will also include a protocol detailing, among other things, the objectives of the clinical trial, the
parameters to be used in monitoring safety and the effectiveness criteria to be evaluated if the first

17

 
 
 
 
 
 
 
 
Table of Contents

phase lends itself to an efficacy determination. The IND automatically becomes effective 30 days after receipt by the FDA,
unless the FDA, within the 30-day time period, places the IND on clinical hold. In such a case, the IND sponsor and the FDA
must resolve any outstanding concerns before clinical trials can begin. A clinical hold may occur at any time during the life
of an IND, and may affect one or more specific clinical trials or all clinical trials conducted under the IND.

All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with
current  GCP  regulations.  They  must  be  conducted  under  protocols  detailing  the  objectives  of  the  trial,  dosing  procedures,
research subject selection and exclusion criteria and the safety and effectiveness criteria to be evaluated. Each protocol must
be submitted to the FDA as part of the IND, and progress reports detailing the status of the clinical trials must be submitted to
the  FDA  annually.  Sponsors  also  must  timely  report  to  FDA  serious  and  unexpected  adverse  reactions,  any  clinically
important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure,
or any findings from other studies or animal or in vitro testing that suggest a significant risk in humans exposed to the drug.
An  IRB  at  each  institution  participating  in  the  clinical  trial  must  review  and  approve  the  protocol  before  the  clinical  trial
commences at that institution and must also approve the information regarding the trial and the consent form that must be
provided  to  each  research  subject  or  the  subject’s  legal  representative,  monitor  the  study  until  completed  and  otherwise
comply with IRB regulations.

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

·

·

·

Phase  1.    The  drug  is  initially  introduced  into  healthy  human  subjects  and  tested  for  safety,  dosage  tolerance,
absorption,  metabolism,  distribution  and  elimination.  In  the  case  of  some  products  for  severe  or  life-threatening
diseases,  such  as  cancer,  and  especially  when  the  product  may  be  inherently  too  toxic  to  ethically  administer  to
healthy volunteers, the initial human testing is often conducted in patients who already have the condition.
Phase 2.  Clinical trials are performed on a limited patient population intended to identify possible adverse effects
and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine
dosage tolerance and optimal dosage.
Phase 3.  If a drug candidate is found to be potentially effective and to have an acceptable safety profile in Phase 2
clinical trials, the clinical trial program will be expanded to Phase 3 clinical trials to further evaluate dosage, clinical
efficacy and safety in an expanded patient population at geographically dispersed clinical trial sites. These studies
are  intended  to  establish  the  overall  risk-benefit  ratio  of  the  product  and  provide  an  adequate  basis  for  product
approval and labeling claims.

Phase 4 clinical trials are conducted after approval to gain additional experience from the treatment of patients in the
intended therapeutic indication and to document a clinical benefit in the case of drugs approved under accelerated approval
regulations, or when otherwise requested by the FDA in the form of post-market requirements or commitments. Failure to
promptly conduct any required Phase 4 clinical trials could result in withdrawal of approval.

Clinical trials are inherently uncertain, and Phase 1, Phase 2 and Phase 3 testing may not be successfully completed.
The FDA or the sponsor may suspend a clinical trial at any time for a variety of reasons, 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.  In  some  cases,  clinical  trials  are  overseen  by  an
independent group of qualified experts organized by the trial sponsor, which is called the clinical monitoring board or data
safety monitoring board. This group provides authorization for whether or not a trial may move forward at designated check
points. These decisions are based on the limited access to data from the ongoing trial.

During  the  development  of  a  new  drug,  sponsors  are  given  opportunities  to  meet  with  the  FDA  at  certain  points.
These points may be prior to the submission of an IND, at the end-of-Phase 2 and before an NDA is submitted. Meetings at
other times may be requested. These meetings can provide an opportunity for the sponsor to share information about the data
gathered to date and for the FDA to provide advice on the next phase of development. Sponsors typically use the meeting at
the end-of-Phase 2 to discuss their Phase 2 clinical trial results and present their plans for the pivotal Phase 3 clinical trial or
trials that they believe will support the approval of the new drug.

18

 
 
 
 
 
 
 
 
Table of Contents

Concurrent  with  clinical  trials,  sponsors  usually  complete  additional  animal  safety  studies  and  also  develop
additional information about the chemistry and physical characteristics of the drug and finalize a process for manufacturing
commercial quantities of the product in accordance with cGMP requirements. The manufacturing process must be capable of
consistently producing quality batches of the drug and the manufacturer must develop methods for testing the quality, purity
and  potency  of  the  drug.  Additionally,  appropriate  packaging  must  be  selected  and  tested,  and  stability  studies  must  be
conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its proposed shelf-life.

The  results  of  product  development,  preclinical  studies  and  clinical  trials,  along  with  descriptions  of  the
manufacturing process, analytical tests and other control mechanisms, proposed labeling and other relevant information are
submitted to the FDA as part of an NDA requesting approval to market the product. The submission of an NDA is subject to
the  payment  of  user  fees,  but  a  waiver  of  such  fees  may  be  obtained  under  specified  circumstances.  The  FDA  reviews  all
NDAs submitted for a period of 60 days to ensure that they are sufficiently complete for substantive review before it accepts
them for filing. It may request additional information rather than accept an NDA for filing. In this event, the NDA must be
resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it
for filing.

During  the  approval  process,  the  FDA  also  will  determine  whether  a  risk  evaluation  and  mitigation  strategy,  or
REMS,  is  necessary  to  assure  the  safe  use  of  the  product.  If  the  FDA  concludes  a  REMS  is  needed,  the  sponsor  of  the
application  must  submit  a  proposed  REMS,  and  the  FDA  will  not  approve  the  application  without  an  approved  REMS,  if
required. A REMS can substantially increase the costs of obtaining approval. The FDA could also require a special warning,
known as a boxed warning, to be included in the product label in order to highlight a particular safety risk.

Once  the  submission  is  accepted  for  filing,  the  FDA  begins  an  in-depth  review.  The  FDA  reviews  an  NDA  to
determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is
cGMP-compliant. The FDA may refer the NDA to an advisory committee for review and recommendation as to whether the
application should be approved and under what conditions. The FDA is not bound by the recommendation of an advisory
committee,  but  it  generally  follows  such  recommendations.  NDAs  receive  either  standard  or  priority  review.  A  drug
representing  a  significant  improvement  in  treatment,  prevention  or  diagnosis  of  disease  may  receive  priority  review.  A
priority review designation is intended to direct overall attention and resources to the evaluation of such applications, and to
shorten the FDA’s goal for taking action on the NDA from ten months to six months from FDA filing of the NDA. After the
FDA evaluates the NDA and conducts inspections of manufacturing facilities where the drug product and/or its API will be
produced, it may 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 is not ready for approval. A Complete Response Letter may
require additional clinical data and/or an additional pivotal Phase 3 clinical trial(s), and/or other significant, expensive and
time-consuming  requirements  related  to  clinical  trials,  preclinical  studies  or  manufacturing.  Even  if  such  data  and
information are submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval.

Post-approval Requirements

Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by
the FDA and other governmental agencies, including, among other things, requirements relating to recordkeeping, periodic
reporting,  product  sampling  and  distribution,  advertising  and  promotion  and  reporting  of  adverse  experiences  with  the
product. Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements is not
maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with
a  product  may  result  in  restrictions  on  the  product  or  even  complete  withdrawal  of  the  product  from  the  market.  After
approval,  some  types  of  changes  to  the  approved  product,  such  as  adding  new  indications,  manufacturing  changes  and
additional  labeling  claims,  are  subject  to  further  FDA  review  and  approval.  There  also  are  continuing,  annual  user  fee
requirements for products and the establishments at which such products are manufactured, as well as new application fees
for  certain  supplemental  applications.  In  addition,  the  FDA  may  require  testing  and  surveillance  programs  to  monitor  the
effect of approved products that have been commercialized, and the FDA has the power to prevent or limit further marketing
of a product based on the results of these post-marketing programs.

Drug 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

19

 
 
 
 
 
 
 
Table of Contents

inspections  by  the  FDA  and  some  state  agencies  for  compliance  with  GMP  regulations  and  other  laws.  The  FDA  has
promulgated specific requirements for drug cGMPs and device cGMPs embodied in the Quality System Regulation. Changes
to  the  manufacturing  process  are  strictly  regulated  and  often  require  prior  FDA  approval  before  being  implemented.  FDA
regulations also require investigation and correction of any deviations from cGMP requirements and impose reporting and
documentation  requirements  upon  the  sponsor  and  any  third-party  manufacturers  that  the  sponsor  may  decide  to  use.
Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to
maintain cGMP compliance.

Failure  to  comply  with  the  applicable  U.S.  requirements  at  any  time  during  the  product  development  process  or
approval process, or after approval, may subject us to administrative or judicial sanctions, any of which could have a material
adverse effect on us. These sanctions could include:

·
·
·
·
·
·
·
·

refusal to approve pending applications;
withdrawal of an approval;
imposition of a clinical hold;
warning letters;
product seizures or detention, or refusal to permit the import or export of products;
restrictions on the marketing or manufacturing of the product;
total or partial suspension of production or distribution or product recalls; or
injunctions, fines, disgorgement, or civil or criminal penalties.

The FDA strictly regulates the marketing, labeling, advertising and promotion of drug 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.  However, companies may share truthful and not misleading information that is otherwise consistent with the product’s
FDA approved labeling. 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.

From  time  to  time,  legislation  is  drafted,  introduced  and  passed  in  Congress  that  could  significantly  change  the
statutory  provisions  governing  the  approval,  manufacturing  and  marketing  of  products  regulated  by  the  FDA.  In  addition,
FDA regulations and guidance are often issued revised or reinterpreted by the agency in ways that may significantly affect
our  business  and  our  products.  It  is  impossible  to  predict  whether  legislative  changes  will  be  enacted,  or  whether  FDA
regulations, guidance or interpretations will be issued or changed or what the impact of such changes, if any, may be.

Non-patent Exclusivity

The  FDCA  provides  a  five-year  period  of  non-patent  marketing  exclusivity  within  the  United  States  to  the  first
applicant to obtain approval of an NDA for a new chemical entity, or NCE. A drug is an NCE 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.  If market exclusivity is granted for an NCE, during the exclusivity period, the FDA may not accept for
review or approve an abbreviated new drug application, or 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 to one of the patents listed with the FDA by the innovator NDA holder.

The FDCA also provides three years of marketing exclusivity for an 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, dosage forms or strengths of
an existing drug.  This three-year exclusivity covers only the conditions associated with the new clinical investigations and
prohibits  the  FDA  from  approving  an  ANDA,  or  a  505(b)(2)  NDA  submitted  by  another  company  with  overlapping
conditions associated with the new clinical investigations for the three-year period.  Clinical investigation exclusivity 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  an  NDA  for  the  same  drug.  However,  an  applicant  submitting  an
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.

Regulation Outside of the United States

In  addition  to  regulations  in  the  United  States,  we  will  be  subject  to  regulations  of  other  countries  governing  our
business activities, including, our clinical trials and the commercial sale and distribution of our product. Even if we obtain
FDA approval for a product, we must obtain approval by the comparable regulatory authorities of countries outside of the
United States before we can commence clinical trials in such countries and approval of the regulators of such countries or
economic  areas,  such  as  the  European  Union  before  we  may  market  products  in  those  countries  or  areas.  The  approval
process  and  requirements  governing  the  conduct  of  clinical  trials,  product  licensing  and  promotion,  pricing  and
reimbursement vary greatly by geographic region, and the time may be longer or shorter than that required for FDA approval.

In the European Economic Area, or EEA, which is composed of the 28 Member States of the European Union plus
Norway,  Iceland  and  Liechtenstein,  medicinal  products  can  only  be  commercialized  after  obtaining  a  Marketing
Authorization, or MA.

There are two types of MAs:

·

·

The Community MA, which is issued by the European Commission through the Centralized Procedure, based on the
opinion of the Committee for Medicinal Products for Human Use, or CHMP, of the European Medicines Agency, or
EMA,  and  which  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,  and  medicinal
products indicated for the treatment of AIDS, cancer, neurodegenerative disorders, diabetes, auto-immune 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. Under the Centralized Procedure, the maximum timeframe for
the evaluation of a marketing authorization application is 210 days (excluding clock stops, when additional written
or oral information is to be provided by the applicant in response to questions asked by the CHMP). Accelerated
evaluation might be granted by the CHMP in exceptional cases, when the authorization of a medicinal product is of
major  interest  from  the  point  of  view  of  public  health  and,  in  particular,  from  the  viewpoint  of  therapeutic
innovation. Under the accelerated procedure, the standard 210 days review period is reduced to 150 days.
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 EEA, 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.

In  the  EEA,  upon  receiving  marketing  authorization,  new  chemical  entities  generally  receive  eight  years  of  data
exclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents regulatory authorities in
the  EEA  from  referencing  the  innovator’s  data  to  assess  a  generic  application.  During  the  additional  two-year  period  of
market exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no
generic product can be marketed until the expiration of the market exclusivity. However, there is no guarantee that a product
will be considered by the EEA’s regulatory authorities to be a new chemical entity, and products may not qualify for data
exclusivity.

Other Health Care Laws

Health care providers, physicians and third-party payors in the United States and elsewhere will play a primary role
in  the  recommendation  and  prescription  of  ESKATA,  RHOFADE  and  any  other  drug  candidates  for  which  we  obtain
marketing approval.  Our arrangements with third-party payors, health care professionals and customers may expose us to
broadly applicable fraud and abuse and other health care laws and regulations, including, without limitation, the federal Anti-
Kickback  Statute  and  the  federal  civil  False  Claims  Act,  that  may  constrain  the  business  or  financial  arrangements  and
relationships through which we sell, market and distribute any drugs for which we obtain marketing approval. In addition, we
may  be  subject  to  transparency  laws  and  patient  privacy  regulation  by  the  federal  government  and  by  the  U.S.  states  and
foreign jurisdictions in which we conduct our business.

The  federal  Anti-Kickback  Statute  makes  it  illegal  for  any  person  or  entity,  including  a  prescription  drug
manufacturer (or a party acting on its behalf) to knowingly and willfully, directly or indirectly, solicit, receive, offer, or pay
any  remuneration  that  is  intended  to  induce  the  referral  of  business,  including  the  purchase,  order,  or  lease  of  any  good,
facility, item or service for which payment may be made under a federal health care program, such as Medicare or Medicaid.
The  term  "remuneration"  has  been  broadly  interpreted  to  include  anything  of  value.  The  Anti-Kickback  Statute  has  been
interpreted  to  apply  to  arrangements  between  pharmaceutical  manufacturers  on  one  hand  and  prescribers,  purchasers,
formulary managers, and beneficiaries on the other. Although there are a number of statutory exceptions and regulatory safe
harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices
that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be
subject to scrutiny if they do not qualify for an exception or safe harbor. Failure to meet all of the requirements of a particular
applicable  statutory  exception  or  regulatory  safe  harbor  does  not  make  the  conduct  per  se  illegal  under  the  Anti-Kickback
Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all
its facts and circumstances. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of
an  arrangement  involving  remuneration  is  to  induce  referrals  of  federal  health  care  covered  business,  the  Anti-Kickback
Statute has been violated. Violations of this law are punishable by up to five years in prison, and can also result in criminal
fines, civil money penalties, administrative penalties and exclusion from participation in federal health care programs.

Additionally,  the  intent  standard  under  the  Anti-Kickback  Statute  was  amended  by  the  Patient  Protection  and
Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the
Affordable Care Act, to a stricter standard such that a person or entity no longer needs to have actual knowledge of the statute
or specific intent to violate it in order to have committed a violation. In addition, the Affordable Care Act codified case law
that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or
fraudulent claim for purposes of the federal civil False Claims Act.

Federal false claims and false statement laws, including the federal civil False Claims Act, prohibits, among other
things, any person or entity from knowingly presenting, or causing to be presented, for payment to, or approval by, federal
programs, including Medicare and Medicaid, claims for items or services, including drugs, that are false or fraudulent or not
provided as claimed. Entities can be held liable under these laws if they are deemed to "cause" the submission of false or
fraudulent claims by, for example, providing inaccurate billing or coding information to customers, promoting a product off-
label, or for providing medically unnecessary services or items. In addition, our activities relating to the sale and marketing
of our products are subject to scrutiny under this law. Penalties for the federal civil False Claims Act violations may include
up  to  three  times  the  actual  damages  sustained  by  the  government,  plus  mandatory  civil  penalties  for  each  separate  false
claim,  the  potential  for  exclusion  from  participation  in  federal  health  care  programs,  and,  although  the  federal  civil  False
Claims Act is a civil statute, False Claims Act violations may also implicate various federal criminal statutes.  For example,
the  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  created  federal  criminal  statutes  that
prohibit among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any health
care benefit program, including private third-party payors, knowingly and willfully embezzling or stealing from a health care
benefit  program,  willfully  obstructing  a  criminal  investigation  of  a  health  care  offense,  and  knowingly  and  willfully
falsifying,  concealing  or  covering  up  a  material  fact  or  making  any  materially  false,  fictitious  or  fraudulent  statement  in
connection with the delivery of or payment for health care benefits, items or services. Like the Anti-Kickback Statute, the
Affordable Care Act amended the intent standard for the health care fraud statute under HIPAA such that a person or entity
no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

The civil monetary penalties statute imposes penalties against any person or entity that, among other things, is

determined to have presented or caused to be presented a claim to a federal health program that the person knows or should
know is for an item or service that was not provided as claimed or is false or fraudulent.

Also, many states have similar fraud and abuse statutes or regulations that may be broader in scope and may apply
regardless of payor, in addition to items and services reimbursed under Medicaid and other state programs. Additionally, to
the extent that our product is sold in a foreign country, we may be subject to similar foreign laws.

In  addition,  legislation  imposing  marketing  restrictions  and  transparency  requirements  on  pharmaceutical
manufacturers has been enacted at the state and federal levels.  For example, the Affordable Care Act imposed, among other
things, annual reporting requirements for covered manufacturers for certain payments and other transfers of value provided to
physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their

22

 
 
 
 
 
 
Table of Contents

immediate family members. Failure to submit timely, accurately and completely the required information for all payments,
transfers  of  value  and  ownership  or  investment  interests  may  result  in  civil  monetary  penalties  for  "knowing
failures."    Certain  states  also  mandate  implementation  of  compliance  programs,  impose  restrictions  on  drug  manufacturer
marketing practices, require registration of certain employees engaged in marketing activities in the location, and/or require
the tracking and reporting of gifts, compensation and other remuneration to physicians. 

Because we are commercializing and intend to commercialize products that are reimbursed under a federal health
care program and other governmental health care programs, we intend to continue to develop a comprehensive compliance
program that establishes internal controls to facilitate adherence to the rules and program requirements to which we will or
may become subject. Although the development and implementation of compliance programs designed to establish internal
controls and facilitate compliance can mitigate the risk of investigation, prosecution, and penalties assessed for violations of
these laws, or any other laws that may apply to us, the risks cannot be entirely eliminated. If our operations are found to be in
violation of any of such laws or any other governmental regulations, we may be subject to significant penalties, including,
without  limitation,  administrative,  civil,  and  criminal  penalties,  damages,  fines,  disgorgement,  contractual  damages,
reputational harm, diminished profits and future earnings, the curtailment or restructuring of our operations, exclusion from
participation in federal and state health care programs, additional reporting requirements and oversight if we become subject
to  a  corporate  integrity  agreement  or  similar  agreement  to  resolve  allegations  of  non-compliance  with  these  laws  and
individual imprisonment, any of which could adversely affect our ability to operate our business and our financial results.

We  may  also  be  subject  to  data  privacy  and  security  regulation  by  both  the  federal  government  and  the  states  in
which  we  conduct  our  business.  HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical
Health Act, or HITECH, and their implementing regulations, including the final omnibus rule published on January 25, 2013,
mandates,  among  other  things,  the  adoption  of  uniform  standards  for  the  electronic  exchange  of  information  in  common
health  care  transactions,  as  well  as  standards  relating  to  the  privacy  and  security  of  individually  identifiable  health
information,  which  require  the  adoption  of  administrative,  physical  and  technical  safeguards  to  protect  such  information.
Among  other  things,  HITECH  makes  HIPAA’s  security  standards  directly  applicable  to  "business  associates",  namely
independent  contractors  or  agents  of  HIPAA  covered  entities  that  create,  receive  or  obtain  protected  health  information  in
connection  with  providing  a  service  for  or  on  behalf  of  a  covered  entity.  HITECH  also  increased  the  civil  and  criminal
penalties  that  may  be  imposed  against  covered  entities  and  business  associates,  and  gave  state  attorneys  general  new
authority  to  file  civil  actions  for  damages  or  injunctions  in  federal  courts  to  enforce  the  federal  HIPAA  laws  and  seek
attorneys’ fees and costs associated with pursuing federal civil actions. In addition, certain state laws govern the privacy and
security of health information in certain circumstances, some of which are more stringent than HIPAA and many of which
differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts. Failure to
comply with these laws, where applicable, can result in the imposition of significant civil and/or criminal penalties.

Health Care Reform

In  the  United  States,  there  have  been  and  continue  to  be  a  number  of  significant  legislative  initiatives  to  contain
health  care  costs.  For  example,  in  March  2010,  the  Affordable  Care  Act  was  passed,  which  has  had,  and  is  expected  to
continue to have, a significant impact on the health care industry. The Affordable Care Act was designed to expand coverage
for the uninsured and at the same time containing overall health care costs. With regard to pharmaceutical products, among
other things, the Affordable Care Act expanded and increased industry rebates for drugs covered under Medicaid programs;
addressed  a  new  methodology  by  which  rebates  owed  by  manufacturers  under  the  Medicaid  Drug  Rebate  Program  are
calculated  for  drugs  that  are  inhaled,  infused,  instilled,  implanted  or  injected;  extended  the  rebate  program  to  individuals
enrolled  in  Medicaid  managed  care  organizations;  established  annual  fees  and  taxes  on  manufacturers  of  certain  branded
prescription drugs; made changes to the coverage requirements under the Medicare prescription drug benefit; and established
a new Medicare Part D coverage gap discount program, in which manufacturers, as a condition for their outpatient drugs to
be covered under Medicare Part D,  must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand
drugs to eligible beneficiaries during their coverage gap period.  Moreover, the Affordable Care Act provided incentives to
programs  that  increase  the  federal  government’s  comparative  effectiveness  research  and  implemented  payment  system
reforms  including  a  national  pilot  program  on  payment  bundling  meant  to  encourage  hospitals,  physicians  and  other
providers to improve the coordination, quality and efficiency of certain health care services.

Since  its  enactment  there  have  been  judicial  and  Congressional  challenges  to,  as  well  efforts  by  the  Trump
Administration to repeal or replace certain aspects of the Affordable Care Act.  For example, since January 2017, President
Trump  has  signed  two  executive  orders  and  other  directives  designed  to  delay,  circumvent,  or  loosen  certain  requirements
mandated  by  the  Affordable  Care  Act.  Concurrently,  Congress  has  considered  legislation  that  would  repeal  or  repeal  and
replace  all  or  part  of  the  Affordable  Care  Act.  While  Congress  has  not  passed  comprehensive  repeal  legislation,  two  bills
affecting the implementation of certain taxes under the Affordable Care Act have been signed into law.  The Tax Cuts and
Jobs  Act  of  2017  includes  a  provision  repealing,  effective  January  1,  2019,  the  tax-based  shared  responsibility  payment
imposed by the Affordable Care Act 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”.  Additionally, on January 22, 2018, President Trump signed a
continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain Affordable Care Act-
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. Further, the Bipartisan Budget Act of 2018, or the BBA, among other things, amended the Affordable Care
Act, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut
hole”.    In  July  2018,  the  Centers  for  Medicare  &  Medicaid  Services,  or  CMS,  published  a  final  rule  permitting  further
collections and payments to and from certain Affordable Care Act qualified health plans and health insurance issuers under
the Affordable Care Act 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
Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of
the  Tax  Cuts  and  Jobs  Act  of  2017.  While  the  Texas  U.S.  District  Court  Judge,  as  well  as  the  Trump  Administration  and
CMS, has 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 Affordable Care Act will impact the Affordable Care Act. 

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted.
For example, in August 2011, President Obama signed into law the Budget Control Act of 2011, which, among other things,
created the Joint Select Committee on Deficit Reduction to recommend to Congress proposals in spending reductions. The
Joint  Select  Committee  on  Deficit  Reduction  did  not  achieve  a  targeted  deficit  reduction  of  at  least  $1.2  trillion  for  fiscal
years  2012  through  2021,  triggering  the  legislation’s  automatic  reduction  to  several  government  programs.  This  includes
aggregate reductions in Medicare payments to providers of 2% per fiscal year, which went into effect beginning on April 1,
2013  and,  due  to  subsequent  legislative  amendments  to  the  statute,  including  the  BBA,  will  stay  in  effect  through  2027,
unless additional Congressional action is taken. Additionally, in January 2013, the American Taxpayer Relief Act of 2012
was signed into law, which, among other things, reduced Medicare payments to several providers, including hospitals, cancer
treatment  centers  and  imaging  centers.  Moreover,  the  Drug  Supply  Chain  Security  Act  imposes  new  obligations  on
manufacturers of pharmaceutical products related to product tracking and tracing. Legislative and regulatory proposals have
been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products.

More recently, there has been heightened governmental scrutiny over the manner in which manufacturers set prices
for their marketed products. Such scrutiny has resulted in several recent Congressional inquiries and proposed and enacted
federal  and  state  legislation  designed  to,  among  other  things,  bring  more  transparency  to  product  pricing,  review  the
relationship  between  pricing  and  manufacturer  patient  programs,  and  reform  government  program  reimbursement
methodologies for products.  At the federal level, the Trump Administration’s budget proposal for fiscal year 2019 contains
further  drug  price  control  measures  that  could  be  enacted  during  the  2019  budget  process  or  in  other  future  legislation,
including, for example, measures to permit Medicare Part D plans to negotiate the price of certain drugs under Medicare Part
B,  to  allow  some  states  to  negotiate  drug  prices  under  Medicaid,  and  to  eliminate  cost  sharing  for  generic  drugs  for  low-
income patients. Further, the Trump Administration released a “Blueprint”, or plan, to lower drug prices and reduce out of
pocket costs of drugs that contains additional proposals to increase drug manufacturer competition, increase the negotiating
power of certain federal health care programs, incentivize manufacturers to lower the list price of their products, and reduce
the out-of-pocket costs of drug products paid by consumers. The Department of Health and Human Services, or HHS, has
already  started  the  process  of  soliciting  feedback  on  some  of  these  measures  and,  at  the  same  time,  is  immediately
implementing  others  under  its  existing  authority.  For  example,  in  September  2018,  CMS  announced  that  it  will  allow
Medicare Advantage plans the option to use step therapy for Part B drugs beginning January 1, 2019, and in October 2018,
CMS  proposed  a  new  rule  that  would  require  direct-to-consumer  television  advertisements  of  prescription  drugs  and
biological products, for which payment is available through or under Medicare or Medicaid, to include in the advertisement
the  Wholesale  Acquisition  Cost,  or  list  price,  of  that  drug  or  biological  product.  On  January  31,  2019,  the  HHS  Office  of
Inspector General proposed modifications to the federal Anti-Kickback Statute discount safe harbor for the

24

 
 
 
Table of Contents

purpose of reducing the cost of drug products to consumers which, among other things, if finalized, will affect discounts paid
by manufacturers to Medicare Part D plans, Medicaid managed care organizations and pharmacy benefit managers working
with  these  organizations.  While  some  of  these  and  other  proposed  measures  may  require  authorization  through  additional
legislation to become effective, Congress and the Trump Administration have both stated that they will continue to seek new
legislative  and/or  administrative  measures  to  control  drug  costs.  At  the  state  level,  legislatures  have  become  increasingly
active in passing legislation and implementing 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.

The Affordable Care Act, as well as other federal and state health care reform measures that have been and may be
adopted in the future, could harm our future revenue.  Additional legislative actions may be taken in the future which may
change current regulations, guidance and interpretations.  The impact of such actions on our business, if any, cannot presently
be determined.

The Hatch Waxman Amendments to the FDC Act

Orange Book Listing

In  seeking  approval  for  a  drug  through  an  NDA,  applicants  are  required  to  list  with  the  FDA  each  patent  whose
claims cover the applicant’s product or a method of using the product. Upon approval of a drug, each of the patents listed in
the  application  for  the  drug  is  then  published  in  the  FDA’s  Approved  Drug  Products  with  Therapeutic  Equivalence
Evaluations,  commonly  known  as  the  Orange  Book.  Drugs  listed  in  the  Orange  Book  can,  in  turn,  be  cited  by  potential
competitors in support of approval of an ANDA or an application covered by Section 505(b)(2) of the FDCA. An ANDA
provides  for  marketing  of  a  drug  product  that  has  the  same  active  ingredients,  generally  in  the  same  strengths  and  dosage
form, as the listed drug and has been shown through pharmacokinetic, or PK, testing to be bioequivalent to the listed drug.
Drugs approved in this way are commonly referred to as "generic equivalents" to the listed drug, and can often be substituted
by pharmacists under prescriptions written for the original listed drug. Other than the requirement for bioequivalence testing,
ANDA applicants are generally not required to conduct, or submit results of, preclinical studies or clinical tests to prove the
safety or effectiveness of their drug product. Section 505(b)(2) applications provide for marketing of a drug product that may
have the same active ingredients as the listed drug and contains full safety and effectiveness data as an NDA, but at least
some of this information comes from studies not conducted by or for the applicant. This alternate regulatory pathway enables
the applicant to rely, in part, on the FDA’s findings of safety and efficacy for an existing product, or published literature, in
support of its application. The FDA may then approve the new drug candidate for all or some of the labeled indications for
which the referenced product has been approved, as well as for any new indication sought by the 505(b)(2) applicant.

The ANDA or Section 505(b)(2) applicant is required to certify to the FDA concerning any patents listed for the
approved product in the FDA’s Orange Book. Specifically, the applicant must certify that: (i) the required patent information
has not been filed; (ii) the listed patent has expired; (iii) the listed patent has not expired, but will expire on a particular date
and approval is sought after patent expiration; or (iv) the listed patent is invalid or will not be infringed by the new product.
The ANDA or Section 505(b)(2) applicant may also elect to submit a statement certifying that its proposed ANDA label does
not contain, or carves out, any language regarding a patented method of use rather than certify to such listed method of use
patent. If the applicant does not challenge the listed patents by filing a certification that the listed patent is invalid or will not
be infringed by the new product, the ANDA or Section 505(b)(2) application will not be approved until all the listed patents
claiming the referenced product have expired.

A  certification  that  the  new  product  will  not  infringe  the  already  approved  product’s  listed  patents,  or  that  such
patents  are  invalid,  is  called  a  Paragraph  IV  certification.  If  the  ANDA  or  Section  505(b)(2)  applicant  has  provided  a
Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA and
patent  holders  once  the  ANDA  or  Section  505(b)(2)  application  has  been  accepted  for  filing  by  the  FDA.  The  NDA  and
patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The
filing of a patent infringement lawsuit within 45 days of the receipt of a Paragraph IV certification automatically prevents the
FDA from approving the ANDA or Section 505(b)(2) application until the earliest of 30 months, expiration of the patent,
settlement  of  the  lawsuit,  and  a  decision  in  the  infringement  case  that  is  favorable  to  the  ANDA  or  Section  505(b)(2)
applicant. This prohibition is generally referred to as the 30-month stay. Thus, approval

25

 
 
 
 
 
 
 
Table of Contents

of an ANDA or 505(b)(2) NDA could be delayed for a significant period of time depending on the patent certification the
applicant makes and the reference drug sponsor’s decision to initiate patent litigation.

The ANDA or Section 505(b)(2) application also will not be approved until any applicable non-patent exclusivity

listed in the Orange Book for the referenced product has expired.

Patent Term Extension

In the United States, after NDA approval, owners of relevant drug patents may apply for up to a five year patent
extension, which provides patent term restoration as compensation for the patent term lost during the FDA regulatory review
process  for  the  first  permitted  commercial  marketing  of  a  drug  product.  The  Drug  Price  Competition  and  Patent  Term
Restoration Act of 1984, or the Hatch-Waxman Act, permits a patent term extension of up to five years beyond the expiration
of the patent. The allowable patent term extension is calculated as half of the drug’s testing phase, which is the time between
the IND submission becoming effective and the NDA submission, and all of the review phase, which is the time between
NDA submission and approval, up to a maximum extension of five years. The time can be shortened if the FDA determines
that the applicant did not pursue approval with due diligence. Patent extension cannot extend the remaining term of a patent
beyond  a  total  of  14  years  from  the  date  of  product  approval  and  only  one  patent  applicable  to  an  approved  drug  may  be
extended. 

Similar provisions are available in the European Union and other foreign jurisdictions to extend the term of a patent
that covers an approved drug. For example, in Japan, it may be possible to extend the patent term for up to five years and in
the  European  Union,  it  may  be  possible  to  obtain  a  supplementary  patent  certificate  that  would  effectively  extend  patent
protection for up to five years.

Coverage and Reimbursement

We do not expect third-party payors to cover and reimburse health care providers who use ESKATA on patients for
the treatment of raised SKs. Third-party payors generally do not reimburse the provider for the product used to remove non-
malignant  lesions,  including  SK.  In  addition,  they  do  not  generally  reimburse  providers  for  the  procedure  removing  such
lesions, since the procedure is considered to be cosmetic in nature, unless there is a medical need to remove the lesion such as
confirming a diagnosis with a biopsy or treating SK that are causing the patient physical discomfort. We anticipate that in
some cases, ESKATA may be used to remove SK lesions that are inflamed and causing the patient discomfort. Any reduction
in reimbursement for the procedure to remove inflamed SK may result in a higher percentage of patients needing to pay out
of  pocket  for  treatment  with  ESKATA.  Accordingly,  the  commercial  success  of  ESKATA  depends  on  the  extent  to  which
patients are willing to pay out of pocket for the in-office procedure using our product.  By contrast, in the case of RHOFADE,
we  believe  our  success  will  depend  on  continued  coverage  and  adequate  reimbursement,  and  in  the  case  of  A-101  45%
Topical Solution for the treatment of common warts or our other drug candidates, if approved, on obtaining and maintaining
coverage  and  adequate  reimbursement,  for  a  prescription  treatment  or  in  the  absence  of  coverage  and  adequate
reimbursement, on the extent to which patients will be willing to pay out of pocket for our prescription drug products.

Third-party payors determine which prescription drug products they will cover and establish reimbursement levels.
Reimbursement by a third-party payor may depend upon a number of factors, including: the third-party payor’s determination
that  a  product  is  safe,  effective,  and  medically  necessary;  appropriate  for  the  specific  patient;  cost-effective;  supported  by
peer-reviewed  medical  journals  or  current  clinical  practice  guidelines;  and  whether  there  are  competitive  products,  either
branded or generic, and the pricing of those products.  Many private third-party payors, such as managed care plans, manage
access to drug products’ coverage partly to control costs for their plans, and may use drug formularies and medical policies to
limit their exposure.  Obtaining and maintaining favorable reimbursement can be a time-consuming and expensive process,
and we may not be able to negotiate or continue to negotiate reimbursement or pricing terms for our products with third-party
payors at levels that are profitable to us, or at all.  

In addition to uncertainties surrounding coverage policies, there are periodic changes to reimbursement.  Third-party
payors  regularly  update  reimbursement  amounts  and  also  from  time  to  time  revise  the  methodologies  used  to  determine
reimbursement  amounts.    Accordingly,  these  updates  could  impact  the  demand  for  RHOFADE  or  A-101  45%  Topical
Solution for the treatment of common warts or our other drug candidates, if approved. Our products may not be considered
cost effective, and government and third-party private health insurance coverage and reimbursement may not be available to
patients or sufficient to allow us to sell our products on a competitive and profitable basis.  Our results of

26

 
 
 
 
 
 
 
 
 
Table of Contents

operations could be adversely affected by the Affordable Care Act and by other health care reforms that may be enacted or
adopted in the future.  In addition, increasing emphasis on managed care in the United States will continue to put pressure on
the  pricing  of  pharmaceutical  products.    Cost  control  initiatives  could  decrease  the  price  that  we  or  any  potential  partners
could receive for any of our products and could adversely affect our profitability.

Foreign governments also have their own health care reimbursement systems, which vary significantly by country
and  region,  and  we  cannot  be  sure  that  coverage  and  adequate  reimbursement  will  be  made  available  with  respect  to  our
products  under  any  foreign  reimbursement  system.    In  some  foreign  countries,  including  major  markets  in  the  European
Union and Japan, the pricing of prescription pharmaceuticals is subject to governmental control.  In these countries, pricing
negotiations  with  governmental  authorities  can  take  up  to  12  months  or  longer  after  the  receipt  of  regulatory  marketing
approval for a product.  To obtain reimbursement or pricing approval in some countries, we may be required to conduct a
pharmacoeconomic  study  that  compares  the  cost-effectiveness  of  our  product  to  other  available  therapies.    Such
pharmacoeconomic studies can be costly and the results uncertain.  Our business could be harmed if reimbursement of our
products is unavailable or limited in scope or amount or if pricing is set at unsatisfactory levels.

Item 1A. Risk Factors

Our  business  is  subject  to  numerous  risks.  You  should  carefully  consider  the  following  risks  and  all  other
information  contained  in  this  Annual  Report,  as  well  as  general  economic  and  business  risks,  together  with  any  other
documents we file with the SEC. If any of the following events actually occur or risks actually materialize, it could have a
material adverse effect on our business, operating results and financial condition and cause the trading price of our common
stock to decline.

Risks Related to Our Business, Our Financial Position and Capital Needs

We have incurred significant losses since our inception. We expect to incur losses over the next several years and

may never achieve or maintain profitability.

We have a limited operating history. Since inception, we have incurred significant net losses. We incurred net losses
of  $132.7  million  and  $68.5  million  for  the  years  ended  December  31,  2018  and  2017,  respectively.  As  of  December  31,
2018, we had an accumulated deficit of $292.2 million. We have financed our operations since inception primarily from sales
of our convertible preferred stock and, beginning with our initial public offering in October 2015, from public offerings and a
private placement of our common stock.  We currently have two products, ESKATA and RHOFADE, that generate revenue
from product sales. 

We have devoted substantially all of our financial resources and efforts to the development of our drug candidates,
including  preclinical  studies  and  clinical  trials,  and  beginning  in  2017,  to  the  commercialization  of  our  products.  Our  net
losses  may  fluctuate  significantly  from  quarter  to  quarter  and  year  to  year.  We  expect  to  continue  to  incur  significant
expenses and operating losses over the next several years as we:

·
·

·

·

·
·

continue to commercialize ESKATA and RHOFADE in the United States;
continue our ongoing clinical trials evaluating A-101 45% Topical Solution for the treatment of common warts and
pursue marketing approvals for A-101 45% Topical Solution and for any other drug candidates that successfully
complete clinical trials;
initiate and continue clinical trials of our other drug candidates, including ATI-501 for the treatment of AA and ATI-
502 for the treatment of AA, vitiligo, AGA and atopic dermatitis;
continue to develop our preclinical drug candidates, including ATI-450, an MK-2 inhibitor, ATI-1777, a soft-JAK
inhibitor, and our ITK inhibitors;
seek to discover and develop additional drug candidates;
continue to develop a commercialization infrastructure and scale up external manufacturing and distribution
capabilities to commercialize our products and any drug candidates for which we may obtain marketing approval;
seek to in-license or acquire additional drug candidates for other dermatological conditions;
adapt our regulatory compliance efforts to incorporate requirements applicable to marketed drugs;

·
·
· maintain, expand and protect our intellectual property portfolio;
hire additional clinical, manufacturing and scientific personnel;
·
add operational, financial and management information systems and personnel, including personnel to support our
·
drug development and commercialization efforts; and
incur additional legal, accounting, investor relations and other administrative expenses in operating as a public
company.

·

To become and remain profitable, we must succeed in commercializing our products and developing and eventually
commercializing  drug  candidates  that  generate  significant  revenue.  This  will  require  us  to  be  successful  in  a  range  of
challenging activities, including completing preclinical testing and clinical trials of our drug candidates, obtaining marketing
approval, and manufacturing, marketing and selling any products and drug candidates for which we have obtained and may
obtain marketing approval, as well as discovering and developing additional drug candidates. We are only in the early stages
of most of these activities. We may never succeed in these activities and, even if we do, may never generate revenue that is
significant enough to achieve profitability.

28

 
 
 
 
 
 
 
 
 
Table of Contents

For ESKATA, RHOFADE and for any drug candidates for which we are successful in obtaining marketing approval,
our revenue is and will continue to be dependent, in part, upon the size of the markets in the territories for which we gain
marketing approval, the accepted price for the product, the ability to obtain coverage and reimbursement, if any, and whether
we own the commercial rights for that territory. If the number of our addressable patients is not as significant as we estimate,
the  indication  approved  by  regulatory  authorities  is  narrower  than  we  expect,  or  the  treatment  population  is  narrowed  by
competition,  physician  choice  or  treatment  guidelines,  we  may  not  generate  significant  revenue  from  sales  of  such  drug
products, even if approved. 

Because  of  the  numerous  risks  and  uncertainties  associated  with  drug  development,  we  are  unable  to  accurately
predict  the  timing  or  amount  of  expenses  or  when,  or  if,  we  will  be  able  to  achieve  profitability.  If  we  are  required  by
regulatory  authorities  to  perform  studies  in  addition  to  those  expected,  or  if  there  are  any  delays  in  the  initiation  and
completion of our clinical trials or the development of any of our drug candidates, our expenses could increase.

Even  if  we  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 depress the value of our company and could impair our ability to
raise capital, expand our business, maintain our development efforts, obtain marketing approvals for our drugs, diversify our
offerings or continue our operations. A decline in the value of our company could also cause you to lose all or part of your
investment.

We  will  need  substantial  additional  funding  to  meet  our  financial  obligations  and  to  pursue  our  business
objectives. If we are unable to raise capital when needed, we could be forced to curtail our planned operations and the
pursuit of our growth strategy. 

Identifying  potential  drug  candidates  and  conducting  preclinical  testing  and  clinical  trials  is  a  time-consuming,
expensive  and  uncertain  process  that  takes  years  to  complete,  and  we  may  never  generate  the  necessary  data  or  results
required  to  obtain  marketing  approval  and  achieve  product  sales.  We  expect  to  continue  to  incur  significant  expenses  and
operating losses over the next several years as we continue to commercialize ESKATA and RHOFADE and conduct clinical
trials  of  and  seek  marketing  approval  for  our  drug  candidates.    In  addition,  ESKATA  and  RHOFADE,  and  our  drug
candidates, if approved, may not achieve commercial success. In addition, if we obtain marketing approval for A-101 45%
Topical  Solution  for  the  treatment  of  common  warts  or  any  other  drug  candidates  that  we  develop,  we  expect  to  incur
additional  significant  commercialization  expenses  related  to  product  sales,  marketing,  distribution  and  manufacturing.  We
also expect an increase in our expenses associated with creating additional infrastructure to support our continuing operations
as a public company.

As of December 31, 2018, we had cash, cash equivalents and marketable securities of $168.0 million. We believe
that our existing cash, cash equivalents and marketable securities as of the date of this Annual Report will enable us to fund
our operating expenses and capital expenditure requirements for a period greater than 12 months from the date of this report
based  on  our  current  operating  assumptions.  These  assumptions  may  prove  to  be  wrong,  and  we  could  use  our  available
capital  resources  sooner  than  we  expect.  Changes  may  occur  beyond  our  control  that  would  cause  us  to  consume  our
available capital before that time, including changes in and progress of our development activities, acquisitions of additional
products  or  drug  candidates,  and  changes  in  regulation.  Our  future  capital  requirements  will  depend  on  many  factors,
including:

·
·
·
·

·

·

·
·
·

·

the extent to which we in-license or acquire additional drug candidates and technologies;
the number and development requirements of the drug candidates that we may pursue;
the costs, timing and outcome of regulatory review of our drug candidates;
the scope, progress, results and costs of preclinical development, laboratory testing and conducting pre-clinical and
clinical trials for our drug candidates;
the cost of commercializing ESKATA and RHOFADE and the costs and timing of future commercialization
activities, including drug manufacturing, marketing, sales and distribution, for any of our drug candidates for which
we receive marketing approval;
the revenue received from commercial sales of ESKATA and RHOFADE and any of our drug candidates for which
we receive marketing approval;
the progress of obtaining marketing approval for ESKATA in select countries in the European Union and Norway;
our ability to establish collaborations to commercialize ESKATA and RHOFADE outside the United States;
the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our
intellectual property rights and defending any intellectual property-related claims; and
the timing, receipt and amount of sales of, or milestone payments related to or royalties on, our current or future
products or drug candidates, if any, as a result of licenses to, or partnership or collaborations with, third parties.

We expect that we will require additional capital to complete the clinical trials for and potentially commercialize A-
101 45% Topical Solution for the treatment of common warts, to complete the clinical development of ATI-501 and ATI-502,
to develop our preclinical compounds, to support our discovery efforts, and to pursue in-licenses or acquisitions of other drug
candidates.    We  also  expect  to  incur  significant  expenses  related  to  the  commercialization  of  ESKATA  and  RHOFADE,
including product manufacturing, sales, marketing, advertising and distribution costs.  In addition, in 2019 we plan to invest
in a new research facility for our drug discovery operations.  Additional funds may not be available on a timely basis, on
commercially  acceptable  terms,  or  at  all,  and  such  funds,  if  raised,  may  not  be  sufficient  to  enable  us  to  continue  to
implement our long-term business strategy. If we are unable to raise sufficient additional capital, we could be forced to curtail
our planned operations and the pursuit of our growth strategy.

We  may  not  be  able  to  generate  sufficient  cash  to  service  our  indebtedness,  including  the  Loan  and  Security

Agreement with Oxford. 

In October 2018, we entered into a loan and security agreement, or the Loan and Security Agreement, with Oxford
Finance  LLC,  or  Oxford,  pursuant  to  which  we  borrowed  $30.0  million  on  October  31,  2018,  and  can  draw  an  additional
$35.0 million until March 31, 2019. Our obligations under the Loan and Security Agreement are secured by substantially all
of our assets except for our intellectual property, and we may not encumber our intellectual property without Oxford's prior
written  consent.  The  Loan  and  Security  Agreement  contains  negative  covenants  restricting  our  activities,  including
limitations on dispositions, mergers or acquisitions, incurring indebtedness or liens, paying dividends or making investments
and  other  specified  business  transactions.  The  Loan  and  Security  Agreement  also  contains  specified  financial  covenants
related  to  us  achieving  specified  minimum  consolidated  revenues  in  future  periods.  Our  obligations  under  the  Loan  and
Security  Agreement  are  subject  to  acceleration  upon  the  occurrence  of  specified  events  of  default,  including  a  material
adverse change in our business, operations or financial or other condition. We may also enter into other debt agreements in
the future which may contain similar or more restrictive terms. 

Our ability to make scheduled monthly payments or to refinance our debt obligations depends on numerous factors,
including the amount of our cash reserves and our actual and projected financial and operating performance. These amounts
and  our  performance  are  subject  to  certain  financial  and  business  factors,  as  well  as  prevailing  economic  and  competitive
conditions, some of which may be beyond our control. We cannot assure you that we will maintain a level of

30

 
 
 
 
 
 
Table of Contents

cash reserves or cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest
on  our  existing  or  future  indebtedness.  If  our  cash  flows  and  capital  resources  are  insufficient  to  fund  our  debt  service
obligations,  we  may  be  forced  to  reduce  or  delay  capital  expenditures,  sell  assets  or  operations,  seek  additional  capital  or
restructure or refinance our indebtedness. We cannot assure you that we would be able to take any of these actions, or that
these  actions  would  permit  us  to  meet  our  scheduled  debt  service  obligations.  Failure  to  comply  with  the  covenants  and
conditions  of  the  Loan  and  Security  Agreement,  including  our  failure  to  achieve  the  minimum  revenue  covenants,  could
result in an event of default, which could result in an acceleration of amounts due under the Loan and Security Agreement.
We may not have sufficient funds or may be unable to arrange for additional financing to repay our indebtedness or to make
any accelerated payments, and Oxford could seek to enforce security interests in the collateral securing such indebtedness,
which would harm our business. 

Because our long-term indebtedness bears interest at rates that fluctuate with changes in certain prevailing

short-term interest rates, we are vulnerable to interest rate increases.

Our long-term indebtedness bears interest at a fluctuating interest rate based on the London interbank offered rate
for  deposits  of  U.S.  dollars  (LIBOR).    LIBOR  tends  to  fluctuate  based  on  general  interest  rates,  rates  set  by  the  Federal
Reserve and other central banks, the supply of and demand for credit in the London interbank market and general economic
conditions. On July 27, 2017, the Financial Conduct Authority (the authority that regulates LIBOR) announced that it intends
to  stop  compelling  banks  to  submit  rates  for  the  calculation  of  LIBOR  after  2021.  It  is  unclear  whether  new  methods  of
calculating LIBOR will be established such that it continues to exist after 2021. The U.S. Federal Reserve, in conjunction
with  the  Alternative  Reference  Rates  Committee,  is  considering  replacing  U.S.  dollar  LIBOR  with  a  newly  created  index,
calculated with a broad set of short-term repurchase agreements backed by treasury securities. It is not possible to predict the
effect of these changes, other reforms or the establishment of alternative reference rates in the United States or elsewhere. To
the extent these interest rates increase, our interest expense will increase, in which event we may have difficulties making
interest payments and funding our other fixed costs, and our available cash flow for general corporate requirements may be
adversely affected.

Raising  additional  capital  may  cause  dilution  to  our  stockholders,  restrict  our  operations  or  require  us  to

relinquish rights to our technologies, products or drug candidates.

Until  such  time,  if  ever,  as  we  can  generate  substantial  revenue,  we  expect  to  finance  our  cash  needs  through  a
combination  of  equity  offerings,  debt  financings  and  license  and  collaboration  agreements.  To  the  extent  that  we  raise
additional capital through the sale of equity securities or convertible debt securities, your ownership interest will be diluted,
and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common
stockholder.  Debt  financing  and  preferred  equity  financing,  if  available,  may  involve  agreements  that  include  covenants
limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or
declaring dividends.

If  we  raise  additional  funds  through  collaborations,  strategic  alliances  or  marketing,  distribution  or  licensing
arrangements with third parties, we may be required to relinquish valuable rights to our technologies, future revenue streams,
products or drug candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional
funds through equity or debt financings or other arrangements with third parties when needed, we may be required to delay,
limit, reduce or terminate our drug development or future commercialization efforts or grant rights to third parties to develop
and market technologies, products or drug candidates that we would otherwise prefer to develop and market ourselves.

We have a limited operating history and a limited history of commercializing drugs, which may make it difficult

for you to evaluate the success of our business to date and to assess our future viability.

We  commenced  operations  in  2012,  and  our  operations  to  date  have  been  largely  focused  on  raising  capital,
developing ESKATA for the treatment of raised SKs, including undertaking preclinical studies and conducting clinical trials,
and acquiring new drug candidates and related intellectual property. We launched ESKATA in the United States in May 2018
and  acquired  RHOFADE  in  November  2018.  We  have  had  limited  time  to  demonstrate  our  ability  to  successfully
manufacture a drug on a commercial scale, or arrange for a third party to do so on our behalf, or conduct sales and marketing
activities necessary for successful commercialization of these products. 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 or

31

 
 
 
 
 
 
 
Table of Contents

a longer history of commercializing drugs. We may also encounter unforeseen expenses, difficulties, complications, delays
and other known or unknown factors in achieving our business objectives.

Our  estimates  of  variable  consideration  related  to  revenue  recognition  from  product  sales  are  difficult  to
estimate, and if our estimates differ significantly from actual product sales, we will be required to record an adjustment in
a subsequent period.

Our estimates of variable consideration related to revenue recognition from product sales are difficult to estimate as
they are based on multiple assumptions which may prove to be incorrect.  For example, we pay certain third-party payors
rebates  with  respect  to  the  utilization  of  RHOFADE  which  are  based  on  contractual  percentages  applied  to  the  amount  of
RHOFADE  prescribed  to  patients  who  are  covered  by  the  plan  or  the  organization  with  which  the  third-party  payor
contracts.  We have a savings card program to provide assistance to eligible patients with out-of-pocket costs for the patient’s
usage of RHOFADE.  Reductions to product sales for the savings card program are estimated based on actual and expected
program  utilization.    We  recognize  revenue  from  product  sales  at  the  point  the  customer  obtains  control,  which  generally
occurs  upon  delivery,  and  also 
is

recognized.    Components  of  variable  consideration  include  trade  discounts  and  allowances,  product  returns,  government
rebates,  discounts  and  rebates,  other  incentives  such  as  patient  co-pay  assistance,  and  other  fee  for  service  amounts.    Our
estimates  of  variable  consideration  are  based  on  assumptions  relating  to,  among  other  things,  the  mix  of  patients  who
purchase  RHOFADE  who  are  fully  insured,  underinsured  and  uninsured  and  the  utilization  of  our  savings  card  program,
rebates, discounts and other pricing concessions and fees. If our estimates of variable consideration differ significantly from
actual  product  sales,  we  will  be  required  to  record  an  adjustment  in  a  subsequent  period  to  reported  product  sales  and
earnings.

Our business and operations would suffer in the event of computer system failures, cyber-attacks or a deficiency

in our cyber-security.

Despite the implementation of security measures, our internal computer systems, and those of third parties on which
we rely, are vulnerable to damage from computer viruses, malware, natural disasters, terrorism, war, telecommunication and
electrical failures, cyber-attacks or cyber-intrusions over the Internet, attachments to emails, persons inside our organization,
or persons with access to systems inside our organization. The risk of a security breach or disruption, particularly through
cyber-attacks  or  cyber  intrusion,  including  by  computer  hackers,  foreign  governments,  and  cyber  terrorists,  has  generally
increased  as  the  number,  intensity  and  sophistication  of  attempted  attacks  and  intrusions  from  around  the  world  have
increased. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of
our drug development programs. For example, the loss of clinical trial data from completed or ongoing or planned clinical
trials could result in delays in our marketing approval efforts and significantly increase our costs to recover or reproduce the
data. To the extent that any disruption or security breach was to result in a loss of or damage to our data or applications, or
inappropriate disclosure of confidential or proprietary information, we could incur material legal claims and liability, damage
to our reputation, and the further development or commercialization of our drug candidates could be delayed.

Risks Related to the Development of Our Drug Candidates

If we are unable to successfully develop, receive marketing approval for and commercialize our drug candidates,

or experience significant delays in doing so, our business will be harmed.

We  have  invested  significant  efforts  and  financial  resources  in  the  development  of  our  drug  candidates  and  the
identification of potential drug candidates. Our ability to generate substantial revenue from our drug candidates will depend
heavily  on  the  successful  development,  marketing  approval  and  eventual  commercialization  of  these  drug  candidates.  The
success of any drug candidates that we develop, including A-101 45% Topical Solution, ATI-501 and ATI-502, will depend
on several factors, including:

·
·

·
·
·

·

·
·

·

successful completion of preclinical studies and our clinical trials;
successful development of our manufacturing processes for any of our drug candidates that receive marketing
approval;
receipt of timely approvals from applicable regulatory authorities;
commercial launch of our drug candidates, if approved;
acceptance of our drug candidates, if approved, by patients, the medical community and third-party payors, and
willingness of patients to pay out of pocket for our drug candidates when third-party payor coverage and
reimbursement is limited or unavailable;
our success in educating physicians and patients about the benefits, administration and use of our drug candidates, if
approved;
the prevalence and severity of adverse events experienced with our drug candidates;
the availability, perceived advantages, cost, safety and efficacy of alternative treatments for the proposed indications
of our drug candidates;
obtaining and maintaining patent, trademark and trade secret protection and regulatory exclusivity for our drug
candidates and otherwise protecting our rights in our intellectual property portfolio;

· maintaining compliance with regulatory requirements, including current good manufacturing practices, or cGMPs;
·
· maintaining a continued acceptable safety, tolerability and efficacy profile of our drugs following approval.

competing effectively with other treatment procedures; and

Whether  marketing  approval  will  be  granted  is  unpredictable  and  depends  upon  numerous  factors,  including  the
substantial discretion of the regulatory authorities. Our drug candidates’ success in clinical trials will not guarantee marketing
approval. If, following submission, our NDA for any drug candidate is not accepted for substantive review, or even if it is
accepted  for  substantive  review,  the  FDA  or  other  comparable  foreign  regulatory  authorities  may  require  that  we  conduct
additional studies or clinical trials, provide additional data, take additional manufacturing steps, or require other conditions
before they will reconsider or approve our application. If the FDA or other comparable foreign regulatory authorities require
additional studies, clinical trials or data, we would incur increased costs and delays in the marketing approval process, which
may  require  us  to  expend  more  resources  than  we  have  available.  In  addition,  the  FDA  or  other  comparable  foreign
regulatory authorities may not consider sufficient any additional required studies, clinical trials, data or information that we
perform and complete or generate, or we may decide to abandon the program.

It  is  possible  that  our  drug  candidates  currently  in  development  will  never  obtain  marketing  approval,  even  if  we
expend substantial time and resources seeking such approval. If we do not achieve one or more of these factors in a timely
manner or at all, we could experience significant delays or an inability to successfully commercialize our drug candidates,
which would harm our business.

Clinical drug development involves a lengthy and expensive process, with an uncertain outcome. We may incur
additional  costs  or  experience  delays  in  completing,  or  ultimately  be  unable  to  complete,  the  development  and
commercialization of our drug candidates.

The risk of failure for our drug candidates is high. It is impossible to predict when or if any of our drug candidates
will prove effective or safe in humans or will receive marketing approval. Before obtaining regulatory approval for the sale
of any drug candidate, we must complete preclinical development and then conduct extensive clinical trials to demonstrate
the safety and efficacy of our drug candidates in humans for use in the target indication. Clinical testing is expensive, difficult
to design and implement, can take many years to complete and is inherently uncertain as to outcome.

33

 
 
 
 
 
 
 
 
Table of Contents

A failure of one or more clinical trials can occur at any stage of testing. The outcome of preclinical testing and early clinical
trials  may  not  be  predictive  of  the  success  of  later  clinical  trials,  and  interim  results  of  a  clinical  trial  do  not  necessarily
predict final results. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and
many  companies  that  have  believed  their  drug  candidates  performed  satisfactorily  in  preclinical  studies  and  clinical  trials
have nonetheless failed to obtain marketing approval of their drugs.

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 our drug candidates, including:

·

·

·

·

·

·

·

·
·

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;
we may experience delays in reaching, or fail to reach, agreement on acceptable clinical trial contracts or clinical
trial protocols with prospective trial sites or prospective contract research organizations, or CROs, the terms of
which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
clinical trials of our drug candidates may produce negative or inconclusive results, including failure to demonstrate
statistical significance, and we may decide, or regulators may require us, to conduct additional clinical trials or
abandon drug development programs;
the number of patients required for clinical trials of our drug 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 or fail to
return for post-treatment follow-up at a higher rate than we anticipate;
our drug candidates may have undesirable side effects or other unexpected characteristics, causing us or our
investigators, regulators or institutional review boards to suspend or terminate the trials;
our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to
us in a timely manner, or at all;
regulators or institutional review boards may require that we or our investigators suspend or terminate clinical
development for various reasons, including noncompliance with regulatory requirements or a finding that the
participants are being exposed to unacceptable health risks;
the cost of clinical trials of our drug candidates may be greater than we anticipate; and
the supply or quality of our drug candidates or other materials necessary to conduct clinical trials of our drug
candidates may be insufficient or inadequate.

We could also encounter delays if a clinical trial is suspended or terminated by us, by the institutional review boards
of the institutions in which such trials are being conducted, by the data safety monitoring board for such trial or by the FDA
or  other  regulatory  authorities.  Such  authorities  may  impose  such  a  suspension  or  termination  due  to  a  number  of  factors,
including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection
of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical
hold,  unforeseen  safety  issues  or  adverse  side  effects,  failure  to  demonstrate  a  benefit  from  using  a  drug,  changes  in
governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial.  If we experience
delays in the completion of, or termination of, any clinical trial of our drug candidates, the commercial prospects of our drug
candidates will be harmed, and our ability to generate product revenues from any of these drug candidates will be delayed. In
addition, any delays in completing our clinical trials will increase our costs, slow down our drug candidate development and
approval process and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences may
harm our business, financial condition and prospects significantly. In addition, many of the factors that cause, or lead to, a
delay in the commencement or completion of clinical trials may also ultimately lead to the denial of marketing approval of
our  drug  candidates.  If  we  are  required  to  conduct  additional  clinical  trials  or  other  testing  of  our  drug  candidates  beyond
those that we currently contemplate, if we are unable to successfully complete clinical trials of our drug candidates or other
testing, if the results of these trials or tests are not favorable or if there are safety concerns, we may:

·
·
·
·
·
·

be delayed in obtaining marketing approval for our drug candidates;
not obtain marketing approval at all;
obtain marketing approval for indications or patient populations that are not as broad as intended or desired;
obtain marketing approval with labeling that includes significant use or distribution restrictions or safety warnings;
be subject to additional post-marketing testing requirements; or
have the drug removed from the market after obtaining marketing approval.

Our drug development costs will also increase if we experience delays in testing or marketing approvals. 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. Significant preclinical study or clinical trial delays also could shorten any periods during
which  we  may  have  the  exclusive  right  to  commercialize  our  drug  candidates  or  allow  our  competitors  to  bring  drugs  to
market before we do and impair our ability to successfully commercialize our drug candidates.

If  we  experience  delays  or  difficulties  in  the  enrollment  of  subjects  in  clinical  trials,  our  receipt  of  necessary

marketing approvals could be delayed or prevented.

Successful and timely completion of clinical trials will require that we enroll a sufficient number of subjects. Subject
enrollment, a significant factor in the timing of clinical trials, is affected by many factors including the size and nature of the
patient population. Trials may be subject to delays as a result of subject enrollment taking longer than anticipated or subject
withdrawal. We may not be able to initiate or continue clinical trials for our drug candidates if we are unable to locate and
enroll  a  sufficient  number  of  eligible  patients  to  participate  in  these  trials  as  required  by  the  FDA  or  similar  regulatory
authorities  outside  the  United  States.  We  cannot  predict  how  successful  we  will  be  at  enrolling  subjects  in  future  clinical
trials. Subject enrollment is affected by other factors including:

·
·
·
·
·
·
·

the eligibility criteria for the trial in question;
the perceived risks and benefits of the drug candidate in the trial;
the availability of drugs approved to treat the skin disease in the trial;
the efforts to facilitate timely enrollment in clinical trials;
the patient referral practices of physicians;
the ability to monitor patients adequately during and after treatment; and
the proximity and availability of clinical trial sites for prospective patients.

Our inability to enroll a sufficient number of subjects for clinical trials would result in significant delays and could
require us or them to abandon one or more clinical trials altogether. Enrollment delays in these clinical trials may result in
increased development costs for our drug candidates, which would cause the value of our company to decline and limit our
ability to obtain additional financing. Furthermore, we rely on and expect to continue to rely on CROs and clinical

35

 
 
 
 
 
 
 
Table of Contents

trial  sites  to  ensure  the  proper  and  timely  conduct  of  our  clinical  trials  and  we  will  have  limited  influence  over  their
performance.

Our clinical trials may fail to demonstrate the safety and efficacy of our drug candidates, or serious adverse or
unacceptable side effects may be identified during the development of our drug candidates, which could prevent or delay
marketing  approval  and  commercialization,  increase  our  costs  or  necessitate  the  abandonment  or  limitation  of  the
development of some of our drug candidates.

Before obtaining marketing approvals for the commercial sale of our drug candidates, we must demonstrate through
lengthy, complex and expensive preclinical testing and clinical trials that our drug candidates are both safe and effective for
use in each target indication, and failures can occur at any stage of testing. Clinical trials often fail to demonstrate safety and
efficacy of the drug candidate studied for the target indication.

If our drug candidates are associated with side effects in clinical trials or have characteristics that are unexpected,
we  may  need  to  abandon  their  development  or  limit  development  to  more  narrow  uses  in  which  the  side  effects  or  other
characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. The FDA or an institutional
review  board  may  also  require  that  we  suspend,  discontinue,  or  limit  our  clinical  trials  based  on  safety  information.  Such
findings  could  further  result  in  regulatory  authorities  failing  to  provide  marketing  authorization  for  our  drug  candidates.
Many  drug  candidates  that  initially  showed  promise  in  early  stage  testing  have  later  been  found  to  cause  side  effects  that
prevented further development of the drug candidate.

Additionally,  if  we  or  others  identify  undesirable  side  effects  caused  by  our  drugs,  a  number  of  potentially

significant negative consequences could result, including:

·
·
·
·
·

regulatory authorities may withdraw approval to market such product;
regulatory authorities may require additional warnings on the labels;
we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;
we could be sued and held liable for harm caused to patients; and
our reputation and physician or patient acceptance of our products may suffer.

Any  of  these  events  could  prevent  us  from  achieving  or  maintaining  market  acceptance  of  the  particular  drug

candidate and could significantly harm our business, results of operations and prospects.

Changes in methods of drug candidate manufacturing or formulation may result in additional costs or delay.

As  drug  candidates  are  developed  through  preclinical  studies  to  late-stage  clinical  trials  towards  approval  and
commercialization,  it  is  common  that  various  aspects  of  the  development  program,  such  as  manufacturing  methods  and
formulation, are altered along the way in an effort to optimize processes and results. Such changes carry the risk that they
will not achieve these intended objectives, and may also require additional testing, FDA notification or FDA approval.  Any
of  these  changes  could  cause  our  drug  candidates  to  perform  differently  and  affect  the  results  of  planned  clinical  trials  or
other  future  clinical  trials  conducted  with  the  altered  materials.   This  could  delay  completion  of  clinical  trials,  require  the
conduct of bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of
our drug candidates and jeopardize our ability to commence sales and generate revenue.

We may not be successful in our efforts to increase our pipeline of drug candidates, including by in-licensing or

acquiring additional drug candidates for other dermatological conditions.

A key element of our strategy is to build and expand our pipeline of drug candidates. In addition, we intend to in-
license or acquire additional drug candidates for other dermatological conditions to build a fully integrated biopharmaceutical
company. We may not be able to identify or develop drug candidates that are safe, tolerable and effective. Even if we are
successful in continuing to build our pipeline, the potential drug candidates that we identify, in-license or acquire may not be
suitable for clinical development, including as a result of being shown to have harmful side effects or other characteristics
that indicate that they are unlikely to be drugs that will receive marketing approval and achieve market acceptance.

36

We may expend our limited resources to pursue a particular drug candidate or indication and fail to capitalize on

drug candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because  we  have  limited  financial  and  management  resources,  we  focus  on  development  programs  and  drug
candidates that we identify for specific indications. As such, we are currently primarily focused on the development of A-101
45% Topical Solution for the treatment of common warts, ATI-501 and ATI-502 for the treatment of AA and ATI-450 for the
treatment of rheumatoid arthritis.  As a result, we may forego or delay pursuit of opportunities with other drug candidates or
for other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to
fail  to  capitalize  on  viable  commercial  drugs  or  profitable  market  opportunities.  Our  spending  on  current  and  future
development programs and drug candidates for specific indications may not yield any commercially viable drugs. If we do
not accurately evaluate the commercial potential or target market for a particular drug candidate, we may relinquish valuable
rights to that drug candidate through collaboration, licensing or other royalty arrangements in cases in which it would have
been more advantageous for us to retain sole development and commercialization rights to such drug candidate.

Risks Related to the Commercialization of ESKATA, RHOFADE and Our Drug Candidates

ESKATA,  RHOFADE  and  any  of  our  drug  candidates  that  receive  marketing  approval  may  fail  to  achieve  the
degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary
for commercial success.

ESKATA, RHOFADE and any of our drug candidates that receive marketing approval, may fail to gain sufficient
market acceptance by physicians, patients, third-party payors and others in the medical community. If ESKATA, RHOFADE
and our drug candidates do not achieve an adequate level of acceptance, we may not generate significant revenue and we may
not become profitable. The degree of market acceptance of ESKATA, RHOFADE and, if approved, any drug candidate, will
depend on a number of factors, including:

·
·
·
·
·
·
·
·
·
·

the efficacy, safety and potential advantages compared to alternative treatments;
our ability to offer our products for sale at competitive prices;
the convenience and ease of administration compared to alternative treatments;
the willingness of the target patient population to try new treatments and of physicians to prescribe these treatments;
our ability to retain a sales force in the United States;
the strength of marketing and distribution support;
the willingness of patients to pay out of pocket for procedures using ESKATA for the treatment of raised SKs;
the availability of third-party payor coverage and adequate reimbursement;
the prevalence and severity of any side effects; and
any restrictions on the use of our products together with other medications.

We have a savings card program for RHOFADE to provide assistance to eligible patients with out-of-pocket costs
for  the  patient’s  usage  of  RHOFADE.  Changes  to  or  elimination  of  the  savings  card  program  could  adversely  affect  the
frequency  with  which  health  care  providers  prescribe  RHOFADE,  the  availability  of  RHOFADE  at  pharmacies  and  the
demand for and use of RHOFADE by patients.  

If we are unable to establish effective sales, marketing and distribution capabilities for ESKATA and RHOFADE,
or  a  drug  candidate  that  may  receive  marketing  approval,  we  may  not  be  successful  in  commercializing  ESKATA  or
RHOFADE or those drug candidates if and when they are approved.

To  achieve  commercial  success  for  ESKATA  and  RHOFADE  and  any  drug  candidate  for  which  we  may  obtain
marketing approval, we will need to build a focused sales and marketing infrastructure to market or co-promote ESKATA and
RHOFADE and, if approved, some of our drug candidates in the United States.  We have begun this process and have hired a
sales  force  for  ESKATA  and  RHOFADE,  but  there  are  risks  involved  with  establishing  our  own  sales,  marketing  and
distribution capabilities. For example, recruiting and training a sales force is expensive and time consuming and could delay
any  drug  launch.  If  the  commercial  launch  of  a  drug  candidate  for  which  we  recruit  a  sales  force  and  establish  marketing
capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred

37

 
 
 
 
 
 
 
 
 
Table of Contents

these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our
sales and marketing personnel.  Factors that may inhibit our efforts to commercialize our drugs on our own include:

·
·

·

·

our inability to recruit, train and retain adequate numbers of effective sales and marketing personnel;
the inability of sales personnel to obtain access to health care providers or persuade adequate numbers of health care
providers to prescribe our products;
the lack of complementary drugs to be offered by sales personnel, which may put us at a competitive disadvantage
relative to companies with more extensive product lines; and
unforeseen costs and expenses associated with creating an independent sales and marketing organization.

If  we  are  unable  to  establish  our  own  effective  sales,  marketing  and  distribution  capabilities  and  enter  into
arrangements with third parties to perform these services, our revenue and our profitability, if any, are likely to be lower than
if  we  were  to  sell,  market  and  distribute  any  drugs  that  we  develop  ourselves.  In  addition,  we  may  not  be  successful  in
entering into arrangements with third parties to sell, market and distribute our drug candidates or may be unable to do so on
terms that are favorable to us. We likely will have little control over such third parties, and any of them may fail to devote the
necessary resources and attention to sell and market our drugs effectively. If we do not establish effective sales, marketing
and  distribution  capabilities,  either  on  our  own  or  in  collaboration  with  third  parties,  we  will  not  be  successful  in
commercializing our products or drug candidates.

We  face  substantial  competition,  which  may  result  in  others  discovering,  developing  or  commercializing  drugs

before or more successfully than we do.

The development and commercialization of new drugs is highly competitive. We face competition with respect to
our  current  products,  and  will  face  competition  with  respect  to  any  drug  candidates  that  we  may  seek  to  develop  or
commercialize  in  the  future,  from  many  different  sources,  including  major  pharmaceutical,  biotechnology  and  specialty
pharmaceutical companies, academic institutions and governmental agencies and public and private research institutions.

With  respect  to  ESKATA  for  the  treatment  of  raised  SKs,  we  are  aware  of  two  biopharmaceutical  companies
developing drug candidates which target SK, one company that is developing a device to target SK, and another company
that  currently  markets  a  line  of  cosmetic  products  targeting  skin  conditions,  including  SK.  We  are  also  aware  of  early
research being conducted with Akt inhibitors as a potential treatment for SK.

With respect to RHOFADE for the treatment of persistent facial erythema (redness) due to rosacea, we are aware of
one other drug that is approved for this indication: MIRVASO (brimonidine) topical gel, 0.33%, which was approved by the
FDA in 2013, is currently marketed by Galderma Laboratories, L.P.

With respect to A-101 45% Topical Solution for the treatment of common warts, we are aware of one company that
received a CE Mark approval for an over-the-counter treatment for the non-surgical removal of warts, and four companies
developing  drug  candidates  for  the  treatment  of  common  warts.  In  addition,  other  drugs  have  been  used  off-label  as
treatments for common warts.

With respect to ATI-501 and ATI-502 for the treatment of AA, we anticipate competing with sensitizing agents such
as  diphencyprone,  and  topical,  intralesional  and  systemic  corticosteroids,  which  have  been  found  to  occasionally  reduce
symptoms of AA. Other treatments utilized for patchy AA include anthralin and minoxidil solution. We may also compete
with  companies  developing  chemical  agents  to  be  used  in  topical  immunotherapies,  as  well  as  companies  developing
biologics, immunosuppressive agents, laser therapy, phototherapy, other JAK inhibitors and prostaglandin analogues to treat
AA.

With respect to ATI-502 for the treatment of vitiligo, we are aware of one other company developing a topical JAK

inhibitor for the treatment of vitiligo.

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

38

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

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 and clinical
development,  obtaining  regulatory  approvals  and  marketing  approved  drugs  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  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 that may be necessary for, our programs.

We  expect  third-party  payors  generally  will  not  cover  the  use  of  ESKATA  for  the  treatment  of  raised  SKs  and,

accordingly, our success will be dependent upon the willingness of patients to pay out of pocket for ESKATA.

We  do  not  expect  third-party  payors  to  cover  and  reimburse  providers  who  use  ESKATA  on  patients  for  the
treatment  of  raised  SKs.  Third-party  payors  generally  do  not  reimburse  the  provider  for  the  product  used  to  remove  non-
malignant  lesions,  including  SK.  In  addition,  they  do  not  generally  reimburse  providers  for  the  procedure  removing  such
lesions, since the procedure is considered to be cosmetic in nature, unless there is a medical need to remove the lesion such as
confirming a diagnosis with a biopsy or treating SK that are causing the patient physical discomfort. We anticipate that in
some cases, ESKATA will be used to remove SK lesions that are inflamed and causing the patient discomfort. Any reduction
in reimbursement for the procedure to remove inflamed SK may result in a higher percentage of patients needing to pay out
of pocket for ESKATA. Accordingly, the commercial success of ESKATA depends on the extent to which patients will be
willing to pay out of pocket for the in-office procedure. 

The success of RHOFADE and A-101 45% Topical Solution for the treatment of common warts or our other drug
candidates, if approved, will depend significantly on coverage and adequate reimbursement or the willingness of patients
to pay for these products.

In the case of RHOFADE, we believe our success will depend on continued coverage and adequate reimbursement,
and in the case of A-101 45% Topical Solution for the treatment of common warts or our other drug candidates, if approved,
on  obtaining  and  maintaining  coverage  and  adequate  reimbursement,  for  a  prescription  treatment  or  in  the  absence  of
coverage  and  adequate  reimbursement,  on  the  extent  to  which  patients  will  be  willing  to  pay  out  of  pocket  for  our
prescription drug products.

Third-party payors determine which prescription drug products they will cover and establish reimbursement levels.
Reimbursement by a third-party payor may depend upon a number of factors, including: the third-party payor’s determination
that  a  product  is  safe,  effective,  and  medically  necessary;  appropriate  for  the  specific  patient;  cost-effective;  supported  by
peer-reviewed  medical  journals  or  current  clinical  practice  guidelines;  and  whether  there  are  competitive  products,  either
branded or generic, and the pricing of those products.  Many private third-party payors, such as managed care plans, manage
access to drug products’ coverage partly to control costs for their plans, and may use drug formularies and medical policies to
limit their exposure.  Obtaining and maintaining favorable reimbursement can be a time-consuming and expensive process,
and we may not be able to negotiate or continue to negotiate reimbursement or pricing terms for our products with third-party
payors at levels that are profitable to us, or at all.  

In addition to uncertainties surrounding coverage policies, there are periodic changes to reimbursement.  Third-party
payors  regularly  update  reimbursement  amounts  and  also  from  time  to  time  revise  the  methodologies  used  to  determine
reimbursement  amounts.    Accordingly,  these  updates  could  impact  the  demand  for  RHOFADE  or  A-101  45%  Topical
Solution for the treatment of common warts or our other drug candidates, if approved. Our products may not be considered
cost effective, and government and third-party private health insurance coverage and reimbursement may not be available to
patients or sufficient to allow us to sell our products on a competitive and profitable basis.  Our results of operations could be
adversely  affected  by  the  Affordable  Care  Act  and  by  other  health  care  reforms  that  may  be  enacted  or  adopted  in  the
future.  In addition, increasing emphasis on managed care in the United States will continue to put pressure on the pricing of
pharmaceutical products.  Cost control initiatives could decrease the price that we or any potential partners could receive for
any  of  our  products  and  could  adversely  affect  our  profitability.    We  cannot  predict  how  pending  and  future  health  care
legislation will impact our business, and any changes in coverage and reimbursement that further restricts coverage of our
products or drug candidates could harm our business.

39

 
 
 
 
 
 
 
 
Table of Contents

Foreign governments also have their own health care reimbursement systems, which vary significantly by country
and  region,  and  we  cannot  be  sure  that  coverage  and  adequate  reimbursement  will  be  made  available  with  respect  to  our
products  under  any  foreign  reimbursement  system.    In  some  foreign  countries,  including  major  markets  in  the  European
Union and Japan, the pricing of prescription pharmaceuticals is subject to governmental control.  In these countries, pricing
negotiations  with  governmental  authorities  can  take  up  to  12  months  or  longer  after  the  receipt  of  regulatory  marketing
approval for a product.  To obtain reimbursement or pricing approval in some countries, we may be required to conduct a
pharmacoeconomic  study  that  compares  the  cost-effectiveness  of  our  product  to  other  available  therapies.    Such
pharmacoeconomic studies can be costly and the results uncertain.  Our business could be harmed if reimbursement of our
products is unavailable or limited in scope or amount or if pricing is set at unsatisfactory levels.

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization

of any of our products or drug candidates that we may develop.

We face an inherent risk of product liability exposure related to the testing of our drug candidates in human clinical
trials  and  an  even  greater  risk  relating  to  the  commercialization  of  ESKATA  and  RHOFADE.  If  we  cannot  successfully
defend  ourselves  against  claims  that  our  drug  candidates  or  drugs  caused  injuries,  we  will  incur  substantial  liabilities.
Regardless of merit or eventual outcome, product liability claims may result in:

·
·
·
·
·
·
·
·
·

decreased demand for our products or any drug candidates that we may develop;
injury to our reputation and significant negative media attention;
withdrawal of clinical trial participants;
significant costs to defend the related litigation;
substantial monetary awards paid to trial participants or patients;
loss of revenue;
reduced resources of our management to pursue our business strategy;
product recall or withdrawal from the market or labeling, marketing or promotional restrictions; and
the inability to commercialize our products or any drug candidates that we may develop.

We currently hold $10 million in product liability insurance coverage in the aggregate, with a per incident limit of
$10  million,  which  may  not  be  adequate  to  cover  all  liabilities  that  we  may  incur.  Insurance  coverage  is  increasingly
expensive.  We  may  need  to  increase  our  insurance  coverage  and  we  may  not  be  able  to  maintain  insurance  coverage  at  a
reasonable cost or in an amount adequate to satisfy any liability that may arise.

Risks Related to Our Dependence on Third Parties

We will rely on third parties to conduct our future clinical trials for drug candidates, and those third parties may

not perform satisfactorily, including failing to meet deadlines for the completion of such trials.

We engage CROs to conduct clinical trials of our drug candidates. We expect to continue to rely on third parties,
such  as  clinical  data  management  organizations,  medical  institutions  and  clinical  investigators,  to  conduct  those  clinical
trials. If any of our relationships with these third parties terminate, we may not be able to timely enter into arrangements with
alternative third parties or to do so on commercially reasonable terms, if at all. In addition, any third parties conducting our
clinical trials will not be our employees, and except for remedies available to us under our agreements with such third parties,
we cannot control whether or not they devote sufficient time and resources to our clinical programs. If these third parties do
not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if
the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols,
regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be
able  to  obtain  marketing  approval  for  or  successfully  commercialize  our  drug  candidates.  Consequently,  our  results  of
operations and the commercial prospects for our drug candidates would be harmed, our costs could increase substantially and
our ability to generate revenue could be delayed significantly.

Switching or adding CROs involves substantial cost and requires management time and focus. In addition, there is a
natural  transition  period  when  a  new  CRO  commences  work.  As  a  result,  delays  occur,  which  can  materially  impact  our
ability to meet our desired clinical development timelines. Though we intend to carefully manage our relationships with our
CROs,  there  can  be  no  assurance  that  we  will  not  encounter  challenges  or  delays  in  the  future  or  that  these  delays  or
challenges will not have a material adverse impact on our business, financial condition and prospects.

40

 
 
 
 
 
 
 
 
 
Table of Contents

We rely on these parties for execution of our preclinical studies and clinical trials, and generally do not control their
activities.  Our  reliance  on  these  third  parties  for  research  and  development  activities  will  reduce  our  control  over  these
activities but will not relieve us of our responsibilities. 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 standards, commonly referred to as good clinical practices, or GCPs, for conducting, recording
and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights,
integrity and confidentiality of trial participants are protected. We also are required to register ongoing clinical trials and post
the results of completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within specified timeframes.
Failure  to  do  so  can  result  in  fines,  adverse  publicity  and  civil  and  criminal  sanctions.  If  we  or  any  of  our  CROs  fail  to
comply with applicable GCPs, 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 complies with GCP regulations. In addition, our clinical trials must be conducted
with  product  produced  under  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 rely on other third parties to store and distribute drug supplies for the commercialization of ESKATA and
RHOFADE  and  for  our  clinical  trials.  Any  performance  failure  on  the  part  of  our  distributors  could  delay  clinical
development or marketing approval of our drug candidates or commercialization of our drugs, producing additional losses
and depriving us of potential revenue.

We contract with third parties for the manufacture of commercial quantities of ESKATA and RHOFADE and for
the supply of our drug candidates for preclinical and clinical testing. This reliance on third parties increases the risk that
we will not have sufficient quantities of ESKATA, RHOFADE or our drug candidates or such quantities at an acceptable
cost, which could delay, prevent or impair our development or commercialization efforts.

We do not have any manufacturing facilities. We currently rely, and expect to continue to rely, on third parties for
the manufacture of commercial quantities of ESKATA and RHOFADE and supply of our drug candidates for preclinical and
clinical testing.  For example, we have entered into an exclusive, ten-year, automatically renewable supply agreement with
PeroxyChem,  a  manufacturer  of  hydrogen  peroxide,  to  provide  the  active  pharmaceutical  ingredient  that  can  be  used  in
ESKATA for the treatment of raised SKs, a manufacturing and supply agreement with a third party for the finished dosage
form  of  RHOFADE,  and  an  exclusive  commercial  supply  agreement  with  James  Alexander  for  the  manufacture  of  the
finished dosage form of ESKATA. This reliance on third parties increases the risk that we will not have sufficient quantities
of our products or drug candidates at an acceptable cost and/or quality, which could delay, prevent or impair our ability to
timely conduct our clinical trials or our other development or commercialization efforts.

The  facilities  used  by  our  contract  manufacturers  to  manufacture  our  products  and  drug  candidates  must  be
approved by the FDA or other regulatory authorities pursuant to inspections that will be conducted after we submit our NDA
or comparable marketing application to the FDA or other regulatory authority. We do not have control over a supplier’s or
manufacturer’s compliance with laws, regulations and applicable cGMP standards and other laws and regulations, such as
those  related  to  environmental  health  and  safety  matters.  If  our  contract  manufacturers  cannot  successfully  manufacture
material that conforms to our specifications and the strict regulatory requirements of the FDA or others, they will not be able
to secure and maintain regulatory approval for their manufacturing facilities. In addition, we have no control over the ability
of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a
comparable foreign regulatory authority does not approve these facilities for the manufacture of our drug candidates or if it
withdraws  any  such  approval  for  our  products  or  drug  candidates  in  the  future,  we  may  need  to  find  alternative
manufacturing facilities, which would significantly impact our ability to commercialize our products and to develop, obtain
regulatory approval for or market, if approved, our drug candidates.

We  may  be  unable  to  establish  any  agreements  with  future  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:

·
·
·
·

·
·

reliance on the third party for regulatory compliance and quality assurance;
the possible breach of the manufacturing agreement by the third party;
the possible misappropriation of our proprietary information, including our trade secrets and know-how;
the possible increase in costs by our third party suppliers for the active pharmaceutical ingredients in ESKATA and
RHOFADE;
the possible increase in costs by our manufacturers for the finished dosage forms of ESKATA and RHOFADE; and
the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for
us.

Third-party  manufacturers  may  not  be  able  to  comply  with  cGMP  regulations  or  similar  regulatory  requirements
outside the United States. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations
could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension
or  withdrawal  of  approvals,  license  revocation,  seizures  or  recalls  of  products,  operating  restrictions  and  criminal
prosecutions, any of which could significantly and adversely affect supplies of our products. 

Our products and drug candidates that we may develop may compete with other products and drug candidates for
access to manufacturing facilities. There are a limited number of manufacturers that operate under cGMP regulations and that
might be capable of manufacturing for us. Any performance failure on the part of our existing or future manufacturers could
delay clinical development or marketing approval. We do not currently have arrangements in place for redundant supply or a
second source for the components of ESKATA or RHOFADE. 

If our current contract manufacturers cannot perform as agreed, we may be required to replace such manufacturers.

We may incur added costs and delays in identifying and qualifying any such replacement.

We expect to continue to depend on third-party contract manufacturers for the foreseeable future. Our current and
anticipated future dependence upon others for the manufacture of our products and drug candidates may adversely affect our
future profit margins and our ability to commercialize any drug candidates that receive marketing approval on a timely and
competitive basis.

We may seek collaborations with third parties for the development or commercialization of our drug candidates.
If  those  collaborations  are  not  successful,  we  may  not  be  able  to  capitalize  on  the  market  potential  of  these  drug
candidates.

We may seek third-party collaborators for the development and commercialization of our drug candidates, including
for the commercialization of any of our drug candidates that are approved for marketing outside the United States. Our likely
collaborators for any collaboration arrangements include large and mid-size pharmaceutical companies, regional and national
pharmaceutical companies and biotechnology companies. If we do enter into any such arrangements with any third parties,
we  will  likely  have  limited  control  over  the  amount  and  timing  of  resources  that  our  collaborators  dedicate  to  the
development  or  commercialization  of  our  drug  candidates.  Our  ability  to  generate  revenue  from  these  arrangements  will
depend on our collaborators’ abilities to successfully perform the functions assigned to them in these arrangements.

42

Collaborations involving our drug candidates would pose the following risks to us:

·

·
·

·

·

·

·

·

·

·

·

collaborators have significant discretion in determining the efforts and resources that they will apply to these
collaborations;
collaborators may not perform their obligations as expected;
collaborators may not pursue development and commercialization of any drug candidates that achieve marketing
approval or may elect not to continue or renew development or commercialization programs based on clinical trial
results, changes in the collaborators’ strategic focus or available funding, or external factors, such as an acquisition,
that divert resources or create competing priorities;
collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or
abandon a drug candidate, repeat or conduct new clinical trials or require a new formulation of a drug candidate for
clinical testing;
collaborators could independently develop, or develop with third parties, products that compete directly or indirectly
with our products or drug candidates if the collaborators believe that competitive products are more likely to be
successfully developed or can be commercialized under terms that are more economically attractive than ours;
drug candidates discovered in collaboration with us may be viewed by our collaborators as competitive with their
own products or drug candidates, which may cause collaborators to cease to devote resources to the
commercialization of our drug candidates, if approved;
a collaborator with marketing and distribution rights to one or more of our drug candidates that achieve marketing
approval may not commit sufficient resources to the marketing and distribution of such drug candidates;
disagreements with collaborators, including disagreements over proprietary rights, contract interpretation or the
preferred course of development, might cause delays or termination of the research, development or
commercialization of drug candidates, might lead to additional responsibilities for us with respect to drug
candidates, or might result in litigation or arbitration, any of which would be time-consuming and expensive;
collaborators may not properly maintain or defend our or their intellectual property rights or may use our or their
proprietary information in such a way as to invite litigation that could jeopardize or invalidate such intellectual
property or proprietary information or expose us to potential litigation;
collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and
potential liability; and
collaborations may be terminated for the convenience of the collaborator and, if terminated, we could be required to
raise additional capital to pursue further development or commercialization of the applicable drug candidates.

Collaboration  agreements  may  not  lead  to  development  or  commercialization  of  drug  candidates  in  the  most
efficient  manner  or  at  all.  If  a  present  or  future  collaborator  of  ours  were  to  be  involved  in  a  business  combination,  the
continued  pursuit  and  emphasis  on  our  drug  development  or  commercialization  program  could  be  delayed,  diminished  or
terminated. 

If we are not able to establish collaborations, we may have to alter our development and commercialization plans.

Our drug development programs and the potential commercialization of our drug candidates will require substantial
additional  capital.  For  some  of  our  drug  candidates,  we  may  decide  to  collaborate  with  pharmaceutical  and  biotechnology
companies for the development and potential commercialization of those drug candidates.

We face significant competition in seeking appropriate collaborators. 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 or similar regulatory authorities
outside the United States, the potential market for the subject drug candidate, the costs and complexities of manufacturing
and delivering such drug candidate to patients, the potential of competing products, the existence of uncertainty with respect
to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the
challenge and industry and market conditions generally. The collaborator may also consider alternative drug candidates or
technologies for similar indications that may be available to collaborate on and whether such

43

 
 
 
 
 
 
Table of Contents

a collaboration could be more attractive than the one with us for our drug candidate. Collaborations are complex and time-
consuming  to  negotiate  and  document.  In  addition,  there  have  been  a  significant  number  of  recent  business  combinations
among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

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 such drug 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 or marketing
activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we
elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain
additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may
not be able to further develop our drug candidates or bring them to market and generate revenue.

Our sublease could terminate if the master lease is terminated for any reason, thus terminating our rights to our

corporate headquarters.

We sublease space for our corporate headquarters.  While the term of the sublease extends until October 2023, if for
any reason the master lease is terminated or expires prior to October 2023, our sublease will also automatically terminate.  In
such an event, we would need to obtain a new direct lease with the master landlord or negotiate and enter into a new lease for
office space at a different location, which we may not be able to do on commercially reasonable terms, if at all.

Risks Related to Our Intellectual Property

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

Our success depends in large part on our ability to obtain and maintain patent protection in the United States and
other countries with respect to our products and drug candidates. We seek to protect our proprietary position by filing patent
applications in the United States and abroad related to our products and drug candidates. 

The  patent  prosecution  process  is  expensive  and  time-consuming,  however,  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. It is also possible that we
will fail to identify patentable aspects of our development output before it is too late to obtain patent protection. We may not
have  the  right  to  control  the  preparation,  filing  and  prosecution  of  patent  applications,  or  to  maintain  the  rights  to  patents
licensed to third parties. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent
with the best interests of our business.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex
legal  and  factual  questions  and  has  in  recent  years  been  the  subject  of  much  litigation.  In  addition,  the  laws  of  foreign
countries may not protect our rights to the same extent as the laws of the United States or vice versa. For example, European
patent law restricts the patentability of methods of treatment of the human body more than U.S. law does. Publications of
discoveries in the 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  or  our  licensors  were  the  first  to  make  the  inventions  claimed  in  our  patents  or  pending
patent applications, or that we or our licensors were the first to file for patent protection of such inventions. As a result, 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 that protect our technology or drugs, in whole or in part, or
which effectively prevent others from commercializing competitive technologies and drugs. 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 preissuance submission of prior art to the U.S. Patent and Trademark
Office,  or  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. An adverse determination in any such
submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third parties to

44

 
 
 
 
 
 
 
 
 
 
Table of Contents

commercialize  our  technology  or  drugs  and  compete  directly  with  us,  without  payment  to  us,  or  result  in  our  inability  to
manufacture  or  commercialize  drugs  without  infringing  third-party  patent  rights.  In  addition,  if  the  breadth  or  strength  of
protection provided by our patents and patent applications that we own, or license is threatened, it could dissuade companies
from collaborating with us to license, develop or commercialize current or future drug candidates. 

Even if our patent applications that we own or license issue as patents, they may not issue in a form that will provide
us  with  any  meaningful  protection,  prevent  competitors  from  competing  with  us  or  otherwise  provide  us  with  any
competitive  advantage.  Our  competitors  may  be  able  to  circumvent  our  patents  by  developing  similar  or  alternative
technologies  or  drugs  in  a  non-infringing  manner.  For  example,  the  patents  and  patent  applications  that  we  exclusively
license from Columbia University that are primarily directed to methods of treating hair loss disorders with JAK inhibitors
may not issue, have issued and or may issue with claims directed to the use of specific JAK inhibitors that we do not intend
to commercialize, or may not issue with claims directed to the use of JAK inhibitors that our competitors may commercialize.

In addition, the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our
patents may be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in loss
of exclusivity or freedom to operate 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 drugs, or
limit  the  duration  of  the  patent  protection  of  our  technology  and  drugs.  Our  issued  U.S.  patents,  with  claims  directed  to
treatment of SK and acrochordons with high-concentration hydrogen peroxide of at least 23%, including ESKATA and A-101
45% Topical Solution, are scheduled to expire in 2022, and our issued U.S. patents with claims directed to high-concentration
hydrogen peroxide formulations, including ESKATA and A-101 45% Topical Solution, and methods of use and applicators
for the same are scheduled to expire in 2035. The issued U.S. patents that we exclusively license from Allergan relating to
methods  of  treating  erythema  associated  with  rosacea  by  topically  administering  oxymetazoline  or  other  alpha-1
adrenoreceptor  agonists,  which  cover  the  approved  use  of  RHOFADE,  expire  between  January  2024  and  May  2028.  The
issued U.S. patent that covers cream formulations of oxymetazoline, including RHOFADE, expires in December 2031. The
issued U.S. patents relating to methods of treating facial erythema associated with rosacea by topically administering once or
twice daily 1% or 1.5% oxymetazoline expire in June 2035. The patents and applications that we exclusively sublicense from
Allergan that may relate to RHOFADE expire in May 2024. Certain issued U.S. patents relating to our JAK inhibitors, ATI-
501 and ATI-502, are scheduled to expire in 2023 and additional U.S. patents, with claims specifically directed to such JAK
inhibitors, are scheduled to expire in 2030. The issued U.S. and Japanese patents that we exclusively license from Columbia
University with claims directed to the use of third party JAK inhibitors for the treatment of hair loss disorders, including AA
and AGA, and inducing hair growth, expire in 2031. We currently do not have any patents issued directed to our soft-JAK
inhibitors, but any claims that may issue would expire in 2038. Our issued U.S. patent covering our lead inhibitors of the
MK-2  signaling  pathway  inhibitor,  expires  in  2034  and  other  issued  patents  covering  different  MK-2  signaling  pathway
inhibitors expire in 2031 and 2032. Our issued patents covering our novel inhibitors of ITK expire between 2035 and 2038.
Given  the  amount  of  time  required  for  the  development,  testing  and  regulatory  review  of  new  drug  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 drugs similar or identical to ours.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could
be expensive, time-consuming and unsuccessful. Further, our issued patents could be found invalid or unenforceable if
challenged in court.

Competitors  may  infringe  our  issued  patents  or  other  intellectual  property.  Our  pending  applications  cannot  be
enforced  against  third  parties  practicing  the  technology  claimed  in  such  applications  unless  and  until  a  patent  issues  from
such applications. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be
expensive  and  time-consuming.  Any  claims  we  assert  against  perceived  infringers  could  provoke  these  parties  to  assert
counterclaims against us alleging that we infringe their patents or that our patents are invalid or unenforceable. 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  insufficient  written  description.  Grounds  for  an  unenforceability  assertion  could  be  an
allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or made a
misleading  statement  during  prosecution.  Third  parties  may  also  raise  similar  claims  before  the  USPTO,  in  post-grant
proceedings  such  as  ex  parte  reexaminations,  inter  partes  review,  or  post-grant  review,  or  oppositions  or  similar
administrative 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. With respect to the

45

 
 
 
 
 
Table of Contents

validity  question,  for  example,  we  cannot  be  certain  that  there  is  no  invalidating  prior  art  of  which  we  and  the  patent
examiner  were  unaware  during  prosecution.  If  a  defendant  were  to  prevail  on  a  legal  assertion  of  invalidity  or
unenforceability, we would lose at least part, and perhaps all, of the patent protection on our products and drug candidates.
Such a loss of patent protection would harm our business. 

In such a proceeding, a court or administrative board may decide that a patent of ours is invalid or unenforceable, in
whole or in part, construe the patent's claims narrowly or refuse to stop the other party from using the technology at issue on
the grounds that our patents do not cover the technology. An adverse result in any such proceeding could put one or more of
our  patents  at  risk  of  being  invalidated  or  interpreted  narrowly.  We  may  find  it  impractical  or  undesirable  to  enforce  our
intellectual  property  against  some  third  parties.  For  instance,  we  are  aware  of  third  parties  that  have  marketed  high-
concentration hydrogen peroxide solutions over the internet for the treatment of SK and warts. These parties do not appear to
have regulatory authority, and we have not authorized them in any way to market these products. However, to date we have
refrained from seeking to enforce our intellectual property rights against these third parties due to the transient nature of their
activities.  

Interference proceedings provoked by third parties or brought by us or declared by the USPTO may be necessary to
determine the priority of inventions with respect to our patents or patent applications. An unfavorable outcome could require
us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be
harmed if the prevailing party does not offer us a license on commercially reasonable terms. 

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.

We are aware that a third party generic pharmaceutical company completed a Phase 3 clinical trial in March 2018
evaluating the reduction in erythema in adults with moderate to severe facial erythema associated with rosacea with a 1%
oxymetazoline topical cream in comparison to an oxymetazoline reference listed drug. While conducting such a clinical trial
may not be an act of patent infringement in the United States, such a clinical trial could serve as the basis for the third party
to file an ANDA or 505(b)(2) application for a generic of RHOFADE that relies in whole or in part on studies conducted by
Allergan,  which  could  trigger  a  potential  patent  infringement  lawsuit.  If  we  were  to  bring  a  patent  infringement  lawsuit
against  such  a  third  party  for  infringing  any  of  the  U.S.  patents  relating  to  methods  of  treating  erythema  associated  with
rosacea  by  topically  administering  oxymetazoline  that  we  exclusively  license  from  Allergan,  we  may  be  required  to  join
Allergan as a party to such a lawsuit. In addition, if we were to bring a patent infringement lawsuit against a third party for
infringing  certain  patents  that  we  sublicense  from  Allergan  relating  to  the  use  of  oxymetazoline  for  treating  rosacea  or
purpura by topical application, we may also be required to join Allergan and another third party as parties to such a lawsuit.
Any such lawsuit could result in the invalidation of, or render unenforceable, some or all of the relevant patent claims or a
finding of non-infringement and the approval of a generic version of RHOFADE sooner than anticipated.

With respect to ATI-501 and ATI-502, if we do not elect to exercise our first right to do so, Rigel may enforce the
licensed patents relating to ATI-501 and ATI-502 against any infringing third party in the field of dermatology. In addition,
Rigel has the first right, but not the obligation, to enforce the licensed patents relating to ATI-501 and ATI-502 against any
infringing party outside of the field of dermatology. With respect to the licensed patents from Columbia University, Columbia
University  has  the  first  right  to  initiate,  control  and  defend  any  proceedings  related  to  the  validity,  enforceability  or
infringement of the licensed patent rights and in doing so, has no obligation to assert more than one licensed patent in one
jurisdiction against a third party. With respect to the licensed patents from Columbia University, if Columbia University does
not  elect  to  exercise  its  first  right  to  do  so,  we  may  enforce  the  licensed  patent  rights  relating  to  an  infringement  of  the
licensed patent rights against any infringing third party.

The RHOFADE patents that we exclusively license from Allergan are subject to a cross-license agreement with a
third party, which place obligations and limitations on our ability to prosecute, maintain and enforce such patents solely
as they relate to an alpha adrenoreceptor agonist that is not oxymetazoline. 

We  exclusively  license  from  Allergan  a  family  of  U.S.  patents  and  applications  relating  to  methods  of  treating
erythema associated with rosacea by topically administering oxymetazoline or other alpha-1 adrenoreceptor agonists, which
expire between January 2024 and May 2028. This patent family covers the approved use of RHOFADE. This patent family is
also subject to an exclusive license granted by Allergan to a third party, which places obligations and limitations

46

 
 
 
 
 
 
 
 
Table of Contents

on our ability to prosecute, maintain and enforce such patents solely as they relate to an alpha adrenoreceptor agonist that is
not oxymetazoline.

If  we  breach  our  license  agreement  with  Rigel,  it  could  compromise  our  development  and  commercialization

efforts for our JAK inhibitors ATI-501 and ATI-502.

In August 2015, we entered into an exclusive license agreement with Rigel, which grants us the rights to certain patent
rights  and  other  intellectual  property  owned  by  them  relating  to  the  JAK  inhibitors  ATI-501  and  ATI-502  in  the  field  of
dermatology. If we materially breach or fail to perform any provision under this license agreement, including failure to make
payments to Rigel when due for royalties and failure to use commercially reasonable efforts to develop and commercialize a
JAK  inhibitor,  Rigel  has  the  right  to  terminate  our  license,  and  upon  the  effective  date  of  such  termination,  our  right  to
practice the licensed Rigel’s patent rights and other intellectual property would end. Any uncured, material breach under the
license agreement could result in our loss of rights to practice the patent rights and other intellectual property licensed to us
under the license agreement with Rigel. 

If we breach our agreement with the Selling Stockholders of Vixen, it could compromise our development and

commercialization efforts for our JAK inhibitors.

In  March  2016,  we  entered  into  a  stock  purchase  agreement  with  the  stockholders  of  Vixen,  pursuant  to  which  we
purchased  all  of  the  stock  of  Vixen  and  assumed  its  license  agreement  with  Columbia  University.    If  we  fail  to  use
commercially  reasonable  efforts  to  develop  and  commercialize  a  JAK  inhibitor  for  AA  and  a  JAK  inhibitor  for  AGA,  the
license agreement with Columbia University will be transferred to the Selling Stockholders of Vixen following any adverse
resolution  of  any  dispute  relating  thereto.    Upon  the  effective  date  of  such  transfer,  our  right  to  practice  the  licensed
Columbia University patent rights and know-how would end. 

If we breach our agreement with Columbia University, it could compromise our development and commercialization

efforts for our JAK inhibitors.

In  March  2016,  as  part  of  the  Vixen  acquisition,  we  assumed  a  license  agreement  with  Columbia  University,  which
grants  us  the  right  under  certain  patent  rights  and  know-how  owned  by  Columbia  University  relating  to  the  use  of  JAK
inhibitors to treat hair-loss disorders. If we materially breach or fail to perform any provision under this license agreement,
including  failure  to  make  payments  to  Columbia  University  when  due  for  royalties  and  failure  to  use  commercially
reasonable  efforts  to  develop  and  commercialize  a  licensed  product,  Columbia  University  has  the  right  to  terminate  our
license, and upon the effective date of such termination, our right to practice the licensed Columbia University patent rights
and  know-how  would  end.  Any  uncured,  material  breach  under  the  license  agreement  could  result  in  our  loss  of  rights  to
practice the patent rights and know-how licensed to us under the license agreement, and, to the extent such patent rights and
know-how relate to our JAK inhibitors, it could compromise our development and commercialization efforts for ATI-501 or
ATI-502. 

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

Filing, prosecuting and defending patents on our products and drug candidates in all countries throughout the world
would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less
extensive  than  those  in  the  United  States.  For  example,  the  use  of  ESKATA  for  the  treatment  of  raised  SKs  is  currently
covered by patents in the United States, Australia, India and New Zealand, but not in the European Union or other countries.
The use of A-101 45% Topical Solution for the treatment of warts is currently covered by issued patents in the United States,
Australia,  India  and  New  Zealand,  but  not  in  the  European  Union  or  other  countries.  A  U.S.  patent  is  issued,  and  patent
applications are pending in the United States, the European Union and other foreign countries directed to high-concentration
hydrogen peroxide formulations, including ESKATA and A-101 45% Topical Solution and methods of use. With respect to
RHOFADE,  the  family  of  patents  and  applications  relating  to  methods  of  treating  erythema  associated  with  rosacea  by
topically  administering  oxymetazoline  or  other  alpha-1  adrenoreceptor  agonists,  which  expire  between  January  2024  and
May 2028, is not filed outside of the United States. Accordingly, the patent protection for RHOFADE outside of the United
States is based upon a family of patents and applications in the United States, the European Union and other major foreign
markets that cover certain cream formulations of oxymetazoline, including RHOFADE, which expires in December 2031 and
a  family  of  patents  and  applications  in  the  United  States,  the  European  Union  and  other  major  foreign  markets  relating  to
methods  of  treating  facial  erythema  associated  with  rosacea  by  topically  administering  once  or  twice  daily  1%  or  1.5%
oxymetazoline, which expires in June 2035. The approved use of RHOFADE

47

 
 
 
 
 
 
 
 
 
Table of Contents

may also be covered by certain patents and applications in the United States, the European Union and other major foreign
markets that expire in May 2024, which we exclusively sublicense from Allergan.

Our JAK inhibitors, ATI-501 and ATI-502, are currently covered in patents and applications in the United States, the
European Union, and other major foreign markets. Additionally, U.S. and Japanese patents have issued in the patent portfolio
licensed from Columbia University, which are directed to the use of certain third party JAK inhibitors for the treatment of
hair  loss  disorders  and  applications  are  pending  in  the  United  States,  the  European  Union,  Japan  and  South  Korea.  In
addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state
laws in the United States. Consequently, we may not be able to prevent third parties from practicing our invention in such
countries.  Competitors  may  use  our  technologies  in  jurisdictions  where  we  have  not  obtained  patent  protection  to  develop
their  own  products  and  may  export  otherwise  infringing  products  to  territories  where  we  have  patent  protection,  but
enforcement rights are not as strong as those in the United States. These products may compete with our products and drug
candidates  and  our  patents  or  other  intellectual  property  rights  may  not  be  effective  or  sufficient  to  prevent  them  from
competing. 

Many companies have encountered significant problems in protecting and defending intellectual property rights in
foreign  jurisdictions.  The  legal  systems  of  some  countries  do  not  favor  the  enforcement  of  patents  and  other  intellectual
property  protection,  which  could  make  it  difficult  for  us  to  stop  the  infringement  of  our  patents  generally.  Proceedings  to
enforce  our  patent  rights  in  foreign  jurisdictions  could  result  in  substantial  costs  and  divert  our  efforts  and  attention  from
other  aspects  of  our  business,  could  put  our  patents  at  risk  of  being  invalidated  or  interpreted  narrowly  and  our  patent
applications  at  risk  of  not  issuing  and  could  provoke  third  parties  to  assert  claims  against  us.  We  may  not  prevail  in  any
lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. 

Many  countries,  including  European  Union  countries,  India,  Japan  and  China,  have  compulsory  licensing  laws
under  which  a  patent  owner  may  be  compelled  under  specified  circumstances  to  grant  licenses  to  third  parties.  In  those
countries, we may have limited remedies if patents are infringed or if we are compelled to grant a license to a third party,
which could materially diminish the value of those patents. This could limit our potential revenue opportunities. Accordingly,
our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial
advantage from the intellectual property that we develop or license.

We may need to license intellectual property from third parties, and such licenses may not be available or may

not be available on commercially reasonable terms.

A  third  party  may  hold  intellectual  property,  including  patent  rights  that  are  important  or  necessary  to  the
development of our products and drug candidates. For example, we exclusively license patents from Allergan related to the
use  of  alpha-1  adrenergic  agonists  for  the  treatment  of  erythema  related  to  rosacea,  which  cover  the  approved  use  of
RHOFDADE,  and  we  exclusively  license  intellectual  property  from  Rigel  in  the  field  of  dermatology  related  to  our  JAK
inhibitors,  ATI-501 and ATI-502.  We also exclusively license intellectual property from Columbia University related to the
use of JAK inhibitors for the treatment of hair loss disorders.  It may be necessary for us to use the patented or proprietary
technology of third parties to commercialize our products and drug candidates, in which case we would be required to obtain
a license from these third parties on commercially reasonable terms, or our business could be harmed, possibly materially. 

Our third-party licensors may develop JAK inhibitors, including those related to our drug candidates, outside of

the field of dermatology.

We  exclusively  license  intellectual  property  from  Rigel  in  order  to  develop,  use,  manufacture,  sell  and
commercialize  ATI-501  and  ATI-502  in  the  field  of  dermatology.  Rigel  has  retained  the  rights  under  such  intellectual
property to develop, use, manufacture, sell and commercialize ATI-501 and ATI-502 outside of the field of dermatology. If
Rigel were to commercialize such JAK inhibitors outside the field of dermatology, such a product could possibly be used off-
label  for  a  dermatology  indication,  which  could  negatively  impact  sales  of  our  drug  candidates,  if  approved.  Rigel  also
retained the intellectual property rights to develop, use, manufacture, sell and commercialize other structurally similar JAK
inhibitors. If Rigel commercializes a structurally similar JAK inhibitor, such a product could directly compete with our drug
candidates, if approved.

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the

outcome of which would be uncertain and could have a material adverse effect on the success of our business.

Our  commercial  success  depends  upon  our  ability  to  develop,  manufacture,  market  and  sell  our  products  or  drug
candidates  and  use  our  proprietary  technologies  without  infringing  the  proprietary  rights  of  third  parties.  There  is
considerable intellectual property litigation in the biotechnology and pharmaceutical industries. We may become party to, or
threatened with, future adversarial proceedings or litigation regarding intellectual property rights with respect to our drugs
and  technology,  including  interference  or  derivation  proceedings  before  the  USPTO.  Numerous  U.S.  and  foreign  issued
patents  and  pending  patent  applications  owned  by  third  parties  exist  in  the  fields  in  which  we  are  developing  our  drug
candidates. Third parties may assert infringement claims against us based on existing patents or patents that may be granted
in the future.

If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from
such third party to continue developing and marketing our drugs and technology. However, we may not be able to obtain any
required  license  on  commercially  reasonable  terms  or  at  all.  Even  if  we  were  able  to  obtain  a  license,  it  could  be  non-
exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forced, including by
court order, to cease commercializing the infringing technology or drug. In addition, we could be found liable for monetary
damages,  including  treble  damages  and  attorneys’  fees  if  we  are  found  to  have  willfully  infringed  a  patent.  A  finding  of
infringement  could  hinder  current  commercialization  efforts  of  our  products  or  prevent  us  from  commercializing  our  drug
candidates,  if  approved,  or  force  us  to  cease  some  of  our  business  operations.  In  the  event  of  a  successful  claim  of
infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful
infringement, pay royalties, redesign our infringing product or obtain one or more licenses from third parties, which may be
impossible  or  require  substantial  time  and  monetary  expenditure.  Claims  that  we  have  misappropriated  the  confidential
information or trade secrets of third parties could have a similar negative impact on our business.

We  may  be  subject  to  claims  by  third  parties  asserting  that  we,  our  employees  or  our  licensors  have

misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.

Many  of  our  employees  and  our  licensors’  employees  were  previously  employed  at  other  biotechnology  or
pharmaceutical companies. Although we and our licensors try to ensure that our employees and our licensors’ employees do
not use the proprietary information or know-how of others in their work for us, we or our licensors may be subject to claims
that  these  employees,  our  licensors  or  we  have  used  or  disclosed  intellectual  property,  including  trade  secrets  or  other
proprietary  information,  of  any  such  employee’s  former  employer.  Litigation  may  be  necessary  to  defend  against  these
claims. 

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

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

Intellectual  property  litigation  could  cause  us  to  spend  substantial  resources  and  distract  our  personnel  from

their normal responsibilities.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause
us  to  incur  significant  expenses,  and  could  distract  our  technical  and  management  personnel  from  their  normal
responsibilities.  In  addition,  there  could  be  public  announcements  of  the  results  of  hearings,  motions  or  other  interim
proceedings  or  developments  and  if  securities  analysts  or  investors  perceive  these  results  to  be  negative,  it  could  have  a
substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our
operating losses and reduce the resources available for development activities or any future sales, marketing or distribution
activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings

49

 
 
 
 
 
 
 
 
 
Table of Contents

adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than
we can because of their greater financial resources. Some of our competitors are larger than we are and have substantially
greater resources. They are, therefore, likely to be able to sustain the costs of complex patent litigation longer than we could.
Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating our
intellectual property. Litigation could result in substantial costs and diversion of management resources, which could harm
our  business.  In  addition,  the  uncertainties  associated  with  litigation  could  compromise  our  ability  to  raise  the  funds
necessary to continue our clinical trials, continue our internal research programs, or in-license needed technology or other
drug candidates. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could
compromise  our  ability  to  compete  in  the  marketplace,  including  compromising  our  ability  to  raise  the  funds  necessary  to
continue  our  clinical  trials,  continue  our  research  programs,  license  necessary  technology  from  third  parties,  or  enter  into
development collaborations that would help us commercialize our drug candidates. 

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be

harmed.

In addition to seeking and maintaining patents for our products and drug candidates, we also rely on trade secrets,
including  unpatented  know-how,  technology  and  other  proprietary  information,  to  maintain  our  competitive  position.  We
seek to protect our trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have
access  to  them,  such  as  our  employees,  corporate  collaborators,  outside  scientific  collaborators,  contract  manufacturers,
consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements
with our employees and consultants. Despite these efforts, any of these parties may breach the agreements and disclose our
proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches.
Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming,
and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling
to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor,
we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to
compete  with  us.  If  any  of  our  trade  secrets  were  to  be  disclosed  to  or  independently  developed  by  a  competitor,  our
competitive position would be harmed. 

The validity, scope and enforceability of any of our patents that cover ESKATA, RHOFADE, A-101 45% Topical

Solution or any of our other drug candidates can be challenged by competitors.

The likelihood that a third party will challenge our patents covering ESKATA or RHOFADE is increased because
these  are  marketed  products.  The  challenge  may  come  in  the  form  of  a  patent  office  proceeding,  such  as  an  inter  partes
review, challenging the validity of the patents or a district court proceeding, such as a paragraph IV litigation arising out of
the filing of an ANDA. 

If a third party files an ANDA or 505(b)(2) application for a generic of ESKATA or RHOFADE, and relies in whole
or in part on studies conducted by or for us, the third party will be required to certify to the FDA that either: (1) there is no
patent  information  listed  in  the  FDA’s  Orange  Book  with  respect  to  our  NDA  for  the  applicable  approved  drug;  (2)  the
patents listed in the Orange Book have expired; (3) the listed patents have not expired, but will expire on a particular date and
approval is sought after patent expiration; or (4) the listed patents are invalid or will not be infringed by the manufacture, use
or sale of the third party's generic drug. A certification that the new drug will not infringe the Orange Book-listed patents for
the applicable approved drug, or that such patents are invalid, is called a paragraph IV certification. If the third party submits
a  paragraph  IV  certification  to  the  FDA,  a  notice  of  the  paragraph  IV  certification  must  also  be  sent  to  us  once  the  third
party's ANDA is accepted for filing by the FDA. We may then initiate a lawsuit to defend the patents identified in the notice.
The  filing  of  a  patent  infringement  lawsuit  within  45  days  of  receipt  of  the  notice  automatically  prevents  the  FDA  from
approving  the  third  party’s  ANDA  until  the  earliest  of  30  months  or  the  date  on  which  the  patent  expires,  the  lawsuit  is
settled,  or  the  court  reaches  a  decision  in  the  infringement  lawsuit  in  favor  of  the  third  party.  If  we  do  not  file  a  patent
infringement lawsuit within the required 45-day period, the third party’s ANDA will not be subject to the 30-month stay of
FDA  approval.  Litigation  or  other  proceedings  to  enforce  or  defend  intellectual  property  rights  are  often  very  complex  in
nature, may be very expensive and time-consuming, may divert our management's attention from our core business, and may
result in unfavorable results that could limit our ability to prevent third parties from competing with ESKATA or RHOFADE.
We are aware that a third party generic pharmaceutical company completed a Phase 3 clinical trial in March 2018 evaluating
the reduction in erythema in adults with moderate to severe facial erythema associated with rosacea with a 1% oxymetazoline
topical cream in comparison to an oxymetazoline reference listed drug. Such a clinical trial could serve as the basis for filing
an ANDA or 505(b)(2)

50

 
 
 
 
 
 
Table of Contents

application  for  a  generic  of  RHOFADE  that  relies  in  whole  or  in  part  on  studies  conducted  by  Allergan,  triggering  the
potential for a paragraph IV certification and subsequent patent infringement lawsuit. Any such lawsuit could result in the
invalidation of, or render unenforceable, some or all of the relevant patent claims or a finding of non-infringement and the
approval of a generic version of RHOFADE sooner than anticipated. 

If  A-101  45%  Topical  Solution,  our  JAK  inhibitors,  or  any  of  our  other  drug  candidates  advance  through
development  or  is  approved  by  the  FDA,  one  or  more  third  parties  may  challenge  the  current  patents,  or  patents  that  may
issue in the future, within our portfolio covering these drug candidates. Any such challenge could result in the invalidation of,
or render unenforceable, some or all of the relevant patent claims or a finding of non-infringement.  

If  we  do  not  obtain  protection  under  the  Hatch-Waxman  Act  by  extending  the  patent  term  and  obtaining  data

exclusivity for our products and drug candidates, our business may be materially harmed.

Our  commercial  success  will  largely  depend  on  our  ability  to  obtain  and  maintain  patent  and  other  intellectual
property in the United States and other countries with respect to our proprietary technology, products, drug candidates and
our target indications.  Our issued U.S. patent with claims directed to treatment of SK with ESKATA is scheduled to expire in
2022  and  our  issued  U.S.  formulation  patent  with  claims  directed  to  high-concentration  hydrogen  peroxide  formulations,
including ESKATA and A-101 45% Topical Solution, and methods of use is scheduled to expire in 2035.  Certain issued U.S.
patents  relating  to  our  JAK  inhibitors,  ATI-501  and  ATI-502,  are  scheduled  to  expire  in  2023  and  additional  U.S.  patents,
with  claims  specifically  directed  to  such  JAK  inhibitors,  are  scheduled  to  expire  in  2030.    The  issued  U.S.  and  Japanese
patents licensed from Columbia University relating to the use of certain third party JAK inhibitor for the treatment of hair
loss disorders, including AA and AGA, and inducing hair growth, expire in 2031.  Our issued U.S. patent covering our lead
inhibitors  of  the  MK-2  signaling  pathway  inhibitor,  expires  in  2034  and  other  issued  patents  covering  different  MK-2
signaling  pathway  inhibitors  expire  in  2031  and  2032.  Our  issued  patents  covering  our  novel  inhibitors  of  ITK  expire
between 2035 and 2038. Given the amount of time required for the development, testing and regulatory review of new drug
candidates,  patents  protecting  our  drug  candidates  might  expire  before  or  shortly  after  such  candidates  begin  to  be
commercialized. We expect to seek extensions of patent terms in the United States and, if available, in other countries where
we are prosecuting patents.

Depending upon the timing, duration and specifics of FDA marketing approval of our drug candidates, one or more
of our U.S. patents may be eligible for limited patent term extension under the Hatch-Waxman Act for a drug candidate. The
Hatch-Waxman  Act  permits  a  patent  extension  term  of  up  to  five  years  beyond  the  normal  expiration  of  the  patent  as
compensation  for  patent  term  lost  during  development  and  the  FDA  regulatory  review  process,  which  is  limited  to  the
approved indication (or any additional indications approved during the period of extension). However, the total patent term
including the period of extension cannot exceed 14 years from the product’s approval date.  Furthermore, this extension is
limited to only one patent per regulatory review period that covers the approved product. However, the applicable authorities,
including the FDA and the USPTO in the United States, and any equivalent regulatory authority in other 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.
We believe that ESKATA is eligible for patent term extension and we have filed an application with the USPTO requesting
patent  term  extension  for  one  patent  that  covers  ESKATA;  however,  the  USPTO  and/or  the  FDA  may  disagree  with  our
interpretation. 

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.  For example, even if we obtain new chemical entity, or NCE, exclusivity for ESKATA, we
could be subject to generic competition as early as the end of the applicable exclusivity period, if our patent portfolio does
not have sufficient term or scope to prevent such generic competition.

Any trademarks we have obtained or may obtain may be infringed or successfully challenged, resulting in harm

to our business.

We expect to rely on trademarks as one means to distinguish any of our products that are approved for marketing

from the products of our competitors. Once we select new trademarks and apply to register them, our trademark

51

 
 
 
 
 
 
 
 
Table of Contents

applications may not be approved. Third parties may oppose or attempt to cancel our trademark applications or trademarks,
or otherwise challenge our use of the trademarks. In the event that our trademarks are successfully challenged, we could be
forced  to  rebrand  our  drugs,  which  could  result  in  loss  of  brand  recognition  and  could  require  us  to  devote  resources  to
advertising  and  marketing  new  brands.  Our  competitors  may  infringe  our  trademarks  and  we  may  not  have  adequate
resources to enforce our trademarks.

Outside  of  the  United  States  we  cannot  be  certain  that  any  country’s  patent  or  trademark  office  will  not
implement new rules that could seriously affect how we draft, file, prosecute and maintain patents, trademarks and patent
and trademark applications.

We cannot be certain that the patent or trademark offices of countries outside the United States will not implement
new rules that increase costs for drafting, filing, prosecuting and maintaining patents, trademarks and patent and trademark
applications or that any such new rules will not restrict our ability to file for patent protection. For example, we may elect not
to seek patent protection in some jurisdictions or for some products or drug candidates in order to save costs. We may be
forced to abandon or return the rights to specific patents due to a lack of financial resources.

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 ESKATA, RHOFADE
and A-101 45% Topical Solution but that are not covered by the claims of the patents that we own;
others may be able to make a JAK inhibitor that is similar to the JAK inhibitors we intend to commercialize that is
not covered by the patents that we exclusively license and have the right to enforce;
we, our licensors or any collaborators might not have been the first to make the inventions covered by the issued
patents or pending patent applications that we own;
we, our licensors or any collaborators 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 pending patent applications will not lead to issued patents;
issued patents that we own or exclusively license 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
we may not develop additional proprietary technologies that are patentable.

Risks Related to Regulatory Approval of Our Drug Candidates and Other Legal Compliance Matters

If we are not able to obtain, or if there are delays in obtaining, required regulatory approvals, we will not be able

to commercialize our drug candidates, and our ability to generate revenue will be materially impaired.

Our  drug  candidates  and  the  activities  associated  with  their  development  and  commercialization,  including  their
design,  testing,  manufacture,  safety,  efficacy,  recordkeeping,  labeling,  storage,  approval,  advertising,  promotion,  sale  and
distribution, are subject to comprehensive regulation by the FDA and other regulatory agencies in the United States and by
the European Commission and EU Member State Competent Authorities and similar regulatory authorities outside the United
States. Failure to obtain marketing approval for a drug candidate will prevent us from commercializing the drug candidate.
Other  than  the  approval  of  ESKATA  in  the  United  States,  Sweden,  United  Kingdom,  Iceland  and  Belgium,  we  have  not
received approval to market any of our drug candidates from regulatory authorities in any jurisdiction. We have only limited
experience  in  filing  and  supporting  the  applications  necessary  to  gain  marketing  approvals.  Securing  marketing  approval
requires  the  submission  of  extensive  preclinical  and  clinical  data  and  supporting  information  to  regulatory  authorities  for
each therapeutic indication to establish the drug candidate’s safety and efficacy. Securing

52

 
 
 
 
 
 
 
 
 
Table of Contents

marketing approval also requires the submission of information about the drug manufacturing process to, and inspection of
manufacturing  facilities  by,  the  regulatory  authorities.  Our  drug  candidates  may  not  be  effective,  may  be  only  moderately
effective or may prove to have undesirable or unintended side effects, toxicities or other characteristics that may preclude our
obtaining marketing approval or prevent or limit commercial use. If any of our drug candidates receive marketing approval,
the accompanying label may limit the approved use of our drug in this way, which could limit sales of the drug. 

The  process  of  obtaining  marketing  approvals,  both  in  the  United  States  and  abroad,  is  expensive  and  may  take
many  years  if  additional  clinical  trials  are  required,  if  approval  is  obtained  at  all,  and  can  vary  substantially  based  upon  a
variety  of  factors,  including  the  type,  complexity  and  novelty  of  the  drug  candidates  involved.  Changes  in  marketing
approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes
in  regulatory  review  for  each  submitted  drug  application,  may  cause  delays  in  the  approval  or  rejection  of  an  application.
Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may
decide  that  our  data  is  insufficient  for  approval  and  require  additional  preclinical,  clinical  or  other  studies.  In  addition,
varying  interpretations  of  the  data  obtained  from  preclinical  and  clinical  testing  could  delay,  limit  or  prevent  marketing
approval of a drug candidate. Any marketing approval we ultimately obtain may be limited or subject to restrictions or post-
approval commitments that render the approved drug not commercially viable.

If we experience delays in obtaining approval or if we fail to obtain approval of our drug candidates, the commercial

prospects for our drug candidates may be harmed and our ability to generate revenue will be materially impaired.

Failure  to  obtain  marketing  approval  in  international  jurisdictions  would  prevent  our  drug  candidates  from

being marketed abroad.

In order to market and sell our drugs in the European Union and any other jurisdictions, we must obtain separate
marketing approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among
countries and can involve additional testing. The time required to obtain approval may differ substantially from that required
to  obtain  FDA  approval.  The  regulatory  approval  process  outside  the  United  States  generally  includes  all  of  the  risks
associated with obtaining FDA approval. In addition, in many countries outside the United States, it is required that the drug
be approved for reimbursement before the drug can be approved for sale in that country. We may not obtain approvals from
regulatory authorities outside the United States on a timely basis, if at all. Approval by the FDA does not ensure approval by
regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside the United States
does  not  ensure  approval  by  regulatory  authorities  in  other  countries  or  jurisdictions  or  by  the  FDA.  However,  failure  to
obtain  approval  in  one  jurisdiction  may  impact  our  ability  to  obtain  approval  elsewhere.  We  may  not  be  able  to  file  for
marketing approvals and may not receive necessary approvals to commercialize our drug candidates in any market.

A variety of risks associated with marketing our drug candidates internationally could harm our business.

We  are  seeking  marketing  approval  for  ESKATA  outside  of  the  United  States,  and  we  may  also  seek  marketing
approval for RHOFADE or our drug candidates currently in development 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 in foreign countries;
the potential for so-called parallel importing, which is what happens when a local seller, faced with high or higher
local prices, opts to import goods from a foreign market (with low or lower prices) rather than buying them locally;
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;
foreign reimbursement, pricing and insurance regimes;
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 of 1977, as amended, or the 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;
logistical challenges resulting from distributing ESKATA, RHOFADE or our drug candidates to foreign countries;
and
business interruptions resulting from geo-political actions, including war and terrorism.

These and other risks associated with our international operations may compromise our ability to achieve or

maintain profitability.

ESKATA, RHOFADE or any drug candidate for which we obtain marketing approval, could be subject to post-
marketing restrictions or recall or withdrawal from the market, and we may be subject to penalties if we fail to comply
with regulatory requirements or if we experience unanticipated problems with our drug candidates, when and if any of
them are approved.

ESKATA, RHOFADE or any drug candidate for which we obtain marketing approval, along with the manufacturing
processes, post-approval clinical data, labeling, advertising and promotional activities for such drug candidate, will be subject
to  continual  requirements  of  and  review  by  the  FDA  and  other  regulatory  authorities.  These  requirements  include
submissions  of  safety  and  other  post-marketing  information  and  reports,  registration  and  listing  requirements,  cGMP
requirements  relating  to  manufacturing,  quality  control,  quality  assurance  and  corresponding  maintenance  of  records  and
documents, requirements regarding the distribution of samples to physicians and recordkeeping. Even if marketing approval
of a drug candidate is granted, the approval may be subject to limitations on the indicated uses for which the drug candidate
may be marketed or to the conditions of approval, including the requirement to implement a risk evaluation and mitigation
strategy. If any of our drug candidates receives marketing approval, the accompanying label may limit the approved use of
our drug, which could limit sales of the drug.

The  FDA  may  also  impose  requirements  for  costly  post-marketing  studies  or  clinical  trials  and  surveillance  to
monitor the safety or efficacy of the drug. The FDA closely regulates the post-approval marketing and promotion of drugs to
ensure drugs are marketed only for the approved indications and in accordance with the provisions of the approved labeling.
The FDA imposes stringent restrictions on manufacturers’ communications regarding off-label use and if we do not market
our drugs for their approved indications, we may be subject to enforcement action for off-label marketing. Violations of the
FDCA  relating  to  the  promotion  of  prescription  drugs  may  lead  to  investigations  alleging  violations  of  federal  and  state
health care fraud and abuse laws, as well as state consumer protection laws.

In addition, later discovery of previously unknown adverse events or other problems with our drugs, manufacturers

or manufacturing processes, or failure to comply with regulatory requirements, may have negative consequences, including:

·
·
·
·
·
·
·
·
·
·
·
·
·

restrictions on such drugs, manufacturers or manufacturing processes;
restrictions on the labeling or marketing of a drug;
restrictions on drug distribution or use;
requirements to conduct post-marketing studies or clinical trials;
warning letters;
recall or withdrawal of the drugs from the market;
refusal to approve pending applications or supplements to approved applications that we submit;
clinical holds;
fines, restitution or disgorgement of profits or revenue;
suspension or withdrawal of marketing approvals;
refusal to permit the import or export of our drugs;
drug seizure; or
injunctions or the imposition of civil or criminal penalties.

Non-compliance  with  the  European  Union’s  requirements  regarding  safety  monitoring  or  pharmacovigilance,  and
with  requirements  related  to  the  development  of  drugs  for  the  pediatric  population,  can  also  result  in  significant  financial
penalties.  Similarly,  failure  to  comply  with  the  European  Union’s  requirements  regarding  the  protection  of  personal
information can also lead to significant penalties and sanctions.

Our  relationships  with  third-party  payors,  health  care  professionals  and  customers  in  the  United  States  and
elsewhere  may  be  subject,  directly  or  indirectly,  to  applicable  anti-kickback,  fraud  and  abuse,  false  claims,  physician
payment transparency, health information privacy and security and other health care laws and regulations, which could
expose us to significant penalties.

Health care providers, physicians and third-party payors in the United States and elsewhere will play a primary role
in the recommendation and prescription of any of our drugs and drug candidates for which we obtain marketing approval.
Our arrangements with third-party payors, health care professionals and customers may expose us to broadly applicable fraud
and abuse and other health care laws and regulations, including, without limitation, the federal Anti-Kickback Statute and the
federal civil False Claims Act, that may constrain the business or financial arrangements and relationships through which we
sell, market and distribute any drugs for which we obtain marketing approval. In addition, we may be subject to transparency
laws and patient privacy regulation by the federal government and by the U.S. states and foreign jurisdictions in which we
conduct our business. The applicable federal, state and foreign health care laws and regulations that may affect our ability to
operate include the following:

·

the  federal  Anti-Kickback  Statute,  which  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 federal and state health care programs such as Medicare and
Medicaid. Further, several courts have interpreted the statute’s intent requirement to mean that if any one purpose of
an  arrangement  involving  remuneration  is  to  induce  referrals  of  federal  health  care  covered  business,  the  Anti-
Kickback  Statute  has  been  violated.    The  intent  standard  was  further  amended  by  the  Affordable  Care  Act,  to  a
stricter  standard  such  that  a  person  or  entity  no  longer  needs  to  have  actual  knowledge  of  the  statute  or  specific
intent  to  violate  it  in  order  to  have  committed  a  violation.    Moreover,  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 False Claims Act;

55

·

·

federal civil and criminal false claims laws, including, without limitation, the federal civil False Claims Act (that
can be enforced through civil whistleblower or qui tam actions), and the civil monetary penalties law, which impose
criminal and civil penalties, against individuals or entities for knowingly presenting, or causing to be presented, to
the  federal  government,  including  the  Medicare  and  Medicaid  programs,  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;

HIPAA, which imposes criminal and civil liability for, among other things, executing a scheme to defraud any health
care benefit program or making false statements relating to health care matters. Similar to the federal Anti-Kickback
Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to
have committed a violation;

HIPAA,  as  amended  by  HITECH,  and  their  respective  implementing  regulations,  which  impose  obligations  on
covered health care providers, health plans, and health care clearinghouses, as well as their business associates that
create, receive, maintain or transmit individually identifiable health information for or on behalf of a covered entity,
with respect to safeguarding the privacy, security and transmission of individually identifiable health information;

the federal Open Payments program, created under Section 6002 of the Affordable Care Act (commonly known as
the Physician Payments Sunshine Act) and its implementing regulations, which requires specified manufacturers of
drugs,  devices,  biologics  or  medical  supplies  for  which  payment  is  available  under  Medicare,  Medicaid  or  the
Children’s Health Insurance Program, with specific exceptions, to report annually to the CMS information related to
payments  or  other  “transfers  of  value”  made  to  physicians,  which  is  defined  to  include  doctors,  dentists,
optometrists,  podiatrists  and  chiropractors,  and  teaching  hospitals,  as  well  as  applicable  manufacturers  to  report
annually to CMS ownership and investment interests held by physicians and their immediate family members. All
such reported information is publicly available; 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  health  care  items  or  services  reimbursed  by  non-
governmental  third-party  payors,  including  private  insurers;  state  and  foreign  laws  that  require  pharmaceutical
companies  to  comply  with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant
compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to
health care providers; state, local and foreign laws that require drug manufacturers to report information related to
payments and other transfers of value to physicians and other health care providers or marketing expenditures; state
laws  that  require  drug  manufacturers  to  report  pricing  information  regarding  certain  drugs;  and/or  that  require
registration  of  certain  employees  engaged  in  marketing  activities  in  the  location;  and  state  and  foreign  laws
governing the privacy and security of health information in certain circumstances, many of which differ from each
other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable health care laws and
regulations  may  involve  substantial  costs.  It  is  possible  that  governmental  authorities  will  conclude  that  our  business
practices,  including  our  relationships  with  physicians  and  other  health  care  providers,  some  of  whom  may  recommend,
purchase  and/or  prescribe  our  products,  may  not  comply  with  current  or  future  statutes,  regulations  or  case  law  involving
applicable  fraud  and  abuse  or  other  health  care  laws  and  regulations.  By  way  of  example,  some  of  our  consulting
arrangements  with  physicians  may  not  meet  all  of  the  criteria  of  the  personal  services  safe  harbor  under  the  federal  Anti-
Kickback  Statute.  Accordingly,  they  may  not  qualify  for  safe  harbor  protection  from  government  prosecution.  A  business
arrangement  that  does  not  substantially  comply  with  a  safe  harbor,  however,  is  not  necessarily  illegal  under  the  Anti-
Kickback Statute, but may be subject to additional scrutiny by the government.

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  civil,  criminal  and  administrative  penalties,  including,  without  limitation,
damages,  fines,  disgorgement,  individual  imprisonment,  exclusion  from  participation  in  government  health  care  programs,
such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity
agreement or similar agreement to resolve allegations of non-compliance with these laws and the curtailment or restructuring
of our operations, which could have a material adverse effect on our business. If any of the physicians or other health care
providers or entities with whom we expect to do business is found not to be in compliance with applicable

56

 
 
 
 
 
 
 
Table of Contents

laws, it may be subject to criminal, civil or administrative sanctions, including exclusions from participation in government
health care programs, which could also materially affect our business.

Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval
of our drug candidates and commercialize our products and drug candidates, if approved, and affect the prices we may
obtain.

In the United States, and some foreign jurisdictions, there have been a number of legislative and regulatory changes
and  proposed  changes  regarding  the  health  care  system  that  could  prevent  or  delay  marketing  approval  of  our  drug
candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any products or drug candidates
for which we obtain marketing approval.

Among  policy  makers  and  payors  in  the  United  States  and  elsewhere,  there  is  significant  interest  in  promoting
changes  in  health  care  systems  with  the  stated  goals  of  containing  health  care  costs,  improving  quality  and/or  expanding
access.  In  the  United  States,  the  pharmaceutical  industry  has  been  a  particular  focus  of  these  efforts  and  has  been
significantly affected by major legislative initiatives.  The Affordable Care Act, which was signed into law in March 2010, is
a  sweeping  law  intended  to  broaden  access  to  health  insurance,  reduce  or  constrain  the  growth  of  health  care  spending,
enhance  remedies  against  fraud  and  abuse,  add  new  transparency  requirements  for  the  health  care  and  health  insurance
industries, impose new taxes and fees on the health industry and impose additional health policy reforms.

Among the provisions of the Affordable Care Act of importance to our products and potential drug candidates are

the following:

·

·

·

·

·

·

·
·
·
·

an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs and
biologic agents, apportioned among these entities according to their market share in certain government health care
programs;
an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to
23.1% and 13.0% of the average manufacturer price for branded and generic drugs, respectively;
expansion of health care fraud and abuse laws, including the False Claims Act and the Anti-Kickback Statute, which
include, among other things, new government investigative powers and enhanced penalties for non-compliance;
a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-
sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap
period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D;
extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in
Medicaid managed care organizations;
expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid
coverage to additional individuals, thereby potentially increasing manufacturers’ Medicaid rebate liability;
expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program;
the new requirements under the federal Open Payments program and its implementing regulations;
a new requirement to annually report drug samples that manufacturers and distributors provide to physicians; and
a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative
clinical effectiveness research, along with funding for such research.

Since  its  enactment  there  have  been  judicial  and  Congressional  challenges  to,  as  well  efforts  by  the  Trump
Administration  to  repeal  or  replace  certain  aspects  of  the  Affordable  Care  Act.  As  a  result,  there  have  been  delays  in  the
implementation  of,  and  action  taken  to  repeal  or  replace,  certain  aspects  of  the  Affordable  Care  Act.    For  example,  since
January 2017, President Trump has signed two executive orders and other directives designed to delay, circumvent, or loosen
certain  requirements  mandated  by  the  Affordable  Care  Act.  Concurrently,  Congress  has  considered  legislation  that  would
repeal  or  repeal  and  replace  all  or  part  of  the  Affordable  Care  Act.  While  Congress  has  not  passed  comprehensive  repeal
legislation, two bills affecting the implementation of certain taxes under the Affordable Care Act have been signed into law.
The  Tax  Cuts  and  Jobs  Act  of  2017  includes  a  provision  that  repealed,  effective  January  1,  2019,  the  tax-based  shared
responsibility  payment  imposed  by  the  Affordable  Care  Act  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”.  Additionally, on January

57

 
 
 
 
 
 
 
Table of Contents

22,  2018,  President  Trump  signed  a  continuing  resolution  on  appropriations  for  fiscal  year  2018  that  delayed  the
implementation  of  certain  Affordable  Care  Act-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. Further, the Bipartisan Budget Act of 2018, or the
BBA, among other things, amended the Affordable Care Act, effective January 1, 2019, to close the coverage gap in most
Medicare drug plans, commonly referred to as the “donut hole”.  In July 2018, CMS published a final rule permitting further
collections and payments to and from certain Affordable Care Act qualified health plans and health insurance issuers under
the Affordable Care Act 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
Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of
the  Tax  Cuts  and  Jobs  Act  of  2017.  While  the  Texas  U.S.  District  Court  Judge,  as  well  as  the  Trump  Administration  and
CMS, has 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 Affordable Care Act will impact the Affordable Care Act. We
continue to evaluate the impact of the Affordable Care Act and efforts to repeal or replace the Affordable Care Act on our
business.

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted.
These changes included aggregate reductions to Medicare payments to providers of 2% per fiscal year that became effective
on April 1, 2013 and, due to subsequent legislative amendments to the statute, including the BBA, will stay in effect through
2027 unless additional Congressional action is taken.  The American Taxpayer Relief Act of 2012, which was signed into law
in January 2013, among other things, further 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. Any similar new laws
may result in additional reductions in Medicare and other health care funding, which could have a material adverse effect on
customers for ESKATA and RHOFADE and, if approved, our drug candidates, and, accordingly, our financial operations.

We expect that the Affordable Care Act, as well as other health care 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  drug.  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 health care reforms
may prevent us from being able to generate revenue, attain profitability, or commercialize our drugs.

Legislative  and  regulatory  proposals  have  been  made  to  expand  post-approval  requirements  and  restrict  sales  and
promotional  activities  for  drugs.    In  addition,  there  has  been  heightened  governmental  scrutiny  in  the  United  States  of
pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. Such scrutiny has resulted in
several  recent  Congressional  inquiries  and  proposed  and  enacted  federal  and  state  legislation  designed  to,  among  other
things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs,
and reform government program reimbursement methodologies for drugs. At the federal level, the Trump Administration’s
budget  proposal  for  fiscal  year  2019  contains  further  drug  price  control  measures  that  could  be  enacted  during  the  2019
budget process or in other future legislation, including, for example, measures to permit Medicare Part D plans to negotiate
the  price  of  certain  drugs  under  Medicare  Part  B,  to  allow  some  states  to  negotiate  drug  prices  under  Medicaid,  and  to
eliminate cost sharing for generic drugs for low-income patients. Further, the Trump Administration released a “Blueprint”,
or  plan,  to  lower  drug  prices  and  reduce  out-of-pocket  costs  of  drugs  that  contains  additional  proposals  to  increase  drug
manufacturer competition, increase the negotiating power of certain federal health care programs, incentivize manufacturers
to lower the list price of their drugs, and reduce the out of pocket costs of drug products paid by consumers. HHS has already
started  the  process  of  soliciting  feedback  on  some  of  these  measures  and,  at  the  same  time,  is  immediately  implementing
others under its existing authority. For example, in September 2018, CMS announced that it will allow Medicare Advantage
plans the option to use step therapy for Part B drugs beginning January 1, 2019, and in October 2018, CMS proposed a new
rule that would require direct-to-consumer television advertisements of prescription drugs and biological products, for which
payment is available through or under Medicare or Medicaid, to include in the advertisement the Wholesale Acquisition Cost,
or  list  price,  of  that  drug  or  biological  product.  On  January  31,  2019,  the  HHS  Office  of  Inspector  General  proposed
modifications to the federal Anti-Kickback Statute discount safe harbor for the purpose of reducing the cost of drug products
to consumers which, among other things, if finalized, will affect discounts paid by manufacturers to Medicare Part D plans,
Medicaid  managed  care  organizations  and  pharmacy  benefit  managers  working  with  these  organizations.  While  some  of
these  and  other  proposed  measures  may  require  authorization  through  additional  legislation  to  become  effective,  Congress
and the Trump Administration have both stated that they will continue to seek new legislative and/or administrative measures
to control drug costs. At the state level,

58

 
 
 
 
Table of Contents

legislatures  have  become  increasingly  active  in  passing  legislation  and  implementing  regulations  designed  to  control
pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on
certain  drug  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  designed  to  encourage
importation  from  other  countries  and  bulk  purchasing    We  cannot  be  sure  whether  additional  legislative  changes  will  be
enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on
the marketing approvals of our drug candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the
FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent drug
labeling and post-marketing testing and other requirements.

If ESKATA is not granted NCE exclusivity from the FDA, our period of marketing exclusivity for ESKATA will

be shorter than previously anticipated, and our business could be harmed. 

Under the FDCA, as amended by the Hatch-Waxman Act, a drug that is granted regulatory approval may be eligible
for  five  years  of  marketing  exclusivity  in  the  United  States  following  regulatory  approval  if  that  drug  is  classified  as  an
NCE.  A drug can be classified as an NCE if the FDA has not previously approved any other drug containing the same active
moiety. 

The  FDA  published  a  determination  on  the  marketing  exclusivity  of  ESKATA  in  a  cumulative  supplement  to  its
Orange Book and determined that ESKATA is eligible for a three-year period of exclusivity for a new product, which would
continue until December 14, 2020, rather than the five-year exclusivity for an NCE.  While we believe we are entitled to an
NCE determination for ESKATA, to date the FDA has not agreed with our position. Although we have appealed the FDA’s
decision,  there  can  be  no  assurance  that  ESKATA  will  be  granted  NCE  exclusivity,  or  that  the  FDA  will  make  a
determination on such appeal of their exclusivity decision in a timely manner. 

NCE marketing exclusivity, if granted, would preclude approval during the five-year exclusivity period of certain
505(b)(2) applications or ANDAs that rely upon the FDA’s findings of safety and efficacy for ESKATA.  However, such an
application  may  be  submitted  after  four  years  if  it  contains  a  certification  of  patent  invalidity  or  non-infringement.  In  this
case, we may be afforded the benefit of a 30-month stay against the launch of such a competitive product that would extend
from  the  end  of  the  five-year  exclusivity  period,  and  may  also  be  afforded  other  extensions  under  applicable  regulations,
including a judicial extension if applicable requirements are met. If we are not able to gain or exploit the period of marketing
exclusivity,  we  may  face  significant  competitive  threats  from  other  manufacturers,  including  the  manufacturers  of  generic
alternatives. Further, even if ESKATA is considered to be an NCE and we are able to gain five-year marketing exclusivity,
another company could challenge that decision to seek to overturn the FDA’s determination.

ESKATA has been granted three years of new product exclusivity under the Hatch-Waxman Amendments. A three-
year period of exclusivity is granted under the Hatch-Waxman Amendments for a drug product that contains an active moiety
that  has  been  previously  approved  when  the  application  contains  reports  of  new  clinical  investigations  (other  than
bioavailability  studies)  conducted  by  the  sponsor  that  were  essential  to  approval  of  the  application.    Our  clinical  trials  of
ESKATA were new clinical investigations that were essential to the approval of our NDA.  We are entitled to at least three-
year exclusivity even if the FDA determines that the hydrogen peroxide moiety was previously approved because our clinical
investigations were essential for the approval of our new drug product, ESKATA. 

Such  three-year  exclusivity  protection  precludes  the  FDA  from  approving  a  marketing  application  for  505(b)(2)
NDA or ANDA for the same conditions of approval as ESKATA for a period of three years from the date of ESKATA’s FDA
approval, i.e., through December 14, 2020 although the FDA may accept and commence review of such applications during
the exclusivity period. This three-year form of exclusivity may also not prevent the FDA from approving an NDA that relies
only  on  its  own  data  to  support  the  change  or  innovation.   Any  loss  of  exclusive  marketing  rights  for  ESKATA  through
introduction of generic or competing products would harm our financial position.

Governments  outside  the  United  States  tend  to  impose  strict  price  controls,  which  may  adversely  affect  our

revenue, if any.

In some countries, particularly the countries of the European Union, the pricing of prescription pharmaceuticals is
subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable
time after the receipt of marketing approval for a drug. To obtain coverage and reimbursement or pricing approval in some
countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our drug candidate to other
available  procedures.  If  reimbursement  of  our  drugs  is  unavailable  or  limited  in  scope  or  amount,  or  if  pricing  is  set  at
unsatisfactory levels, our business could be harmed, possibly materially. 

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 harm our business.

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

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 maintain insurance for environmental liability or toxic tort claims that may be asserted
against us in connection with our storage or disposal of biological, hazardous or radioactive materials.

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 development or production efforts.
Our failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions. 

The inherent dangers in production and transportation of hydrogen peroxide could cause disruptions and could

expose us to potentially significant losses, costs or liabilities.

Our operations are subject to significant hazards and risks inherent in the use and transport of hydrogen peroxide,
the active ingredient of ESKATA and A-101 45% Topical Solution. Hydrogen peroxide can decompose in the presence of
organic materials and is categorized as an oxidizer and is corrosive. Hydrogen peroxide should be stored in cool, dry, well-
ventilated areas and away from any flammable or combustible substances. The hazards and risks associated with producing
and transporting hydrogen peroxide include fires, explosions, third-party interference (including terrorism) and mechanical
failure of equipment at our facilities or those of our supplier of hydrogen peroxide. The occurrence of any of these events
could  result  in  production  and  distribution  difficulties  and  disruptions,  personal  injury  or  wrongful  death  claims  and  other
damage to properties.

We are subject to governmental economic sanctions and export and import controls that could impair our ability

to compete in international markets or subject us to liability if we are not in compliance with applicable laws.

As a U.S. company, we are subject to U.S. import and export controls and economic sanctions laws and regulations,
and we are required to import and export our products and drug candidates, technology and services in compliance with those
laws and regulations, including the U.S. Export Administration Regulations, the International Traffic in Arms Regulations,
and  economic  embargo  and  trade  sanction  programs  administered  by  the  Treasury  Department’s  Office  of  Foreign  Assets
Control. 

U.S.  economic  sanctions  and  export  control  laws  and  regulations  prohibit  the  shipment  of  certain  products  and
services  to  countries,  governments  and  persons  targeted  by  U.S.  sanctions.  While  we  are  currently  taking  precautions  to
prevent doing any business, directly or indirectly, with countries, governments and persons targeted by U.S. sanctions and

60

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

to ensure that our products and drug candidates, are not exported or used by countries, governments and persons targeted by
U.S. sanctions, such measures may be circumvented. 

Furthermore,  if  we  export  our  products  or  drug  candidates,  the  exports  may  require  authorizations,  including  a
license,  a  license  exception  or  other  appropriate  government  authorization.  Complying  with  export  control  and  sanctions
regulations for a particular sale may be time-consuming and may result in the delay or loss of sales opportunities. Failure to
comply with export control and sanctions regulations for a particular sale may expose us to government investigations and
penalties. 

If  we  are  found  to  be  in  violation  of  U.S.  sanctions  or  import  or  export  control  laws,  it  could  result  in  civil  and
criminal,  monetary  and  non-monetary  penalties,  including  possible  incarceration  for  those  individuals  responsible  for  the
violations, the loss of export or import privileges and reputational harm.

We  are  subject  to  anti-corruption  and  anti-money  laundering  laws  with  respect  to  our  operations  and  non-

compliance with such laws can subject us to criminal and/or civil liability and harm our business.

We are subject to the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the
USA  PATRIOT  Act  and  possibly  other  anti-bribery  and  anti-money  laundering  laws  in  countries  in  which  we  conduct
activities.  Anti-corruption  laws  are  interpreted  broadly  and  prohibit  companies  and  their  employees  and  third-party
intermediaries from authorizing, offering or providing, directly or indirectly, improper payments or benefits to recipients in
the  public  or  private  sector.  As  we  commercialize  our  drug  candidates  and  eventually  commence  international  sales  and
business, we may engage with collaborators and third-party intermediaries to sell our products abroad and to obtain necessary
permits, licenses and other regulatory approvals. We or our third-party intermediaries may have direct or indirect interactions
with  officials  and  employees  of  government  agencies  or  state-owned  or  affiliated  entities.  We  can  be  held  liable  for  the
corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners and
agents, even if we do not explicitly authorize such activities. 

Noncompliance with anti-corruption and anti-money laundering laws could subject us to whistleblower complaints,
investigations,  sanctions,  settlements,  prosecution,  other  enforcement  actions,  disgorgement  of  profits,  significant  fines,
damages,  other  civil  and  criminal  penalties  or  injunctions,  suspension  and/or  debarment  from  contracting  with  certain
persons,  the  loss  of  export  privileges,  reputational  harm,  adverse  media  coverage  and  other  collateral  consequences.
Responding to any action will likely result in a materially significant diversion of management’s attention and resources and
significant defense costs and other professional fees.

Risks Related to Employee Matters and Managing Our Growth

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified

personnel.

We  are  highly  dependent  on  the  management,  development,  clinical,  financial,  legal  and  business  development
expertise of Dr. Neal Walker, our Chief Executive Officer, Dr. Stuart Shanler, our Chief Scientific Officer, Dr. David Gordon,
our Chief Medical Officer, Frank Ruffo, our Chief Financial Officer, and Kamil Ali-Jackson, our Chief Legal Officer, as well
as  the  other  members  of  our  scientific  and  clinical  teams.  Although  we  have  entered  into  employment  agreements  with
certain of our executive officers, each of them may currently terminate their employment with us or resign at any time. We do
not maintain “key person” insurance for any of our key executives other than for Dr. Walker. 

Recruiting and retaining qualified scientific and clinical personnel and, if we progress the development of our drug
pipeline toward scaling up for commercialization, manufacturing and sales and marketing personnel, will also be critical to
our success. The loss of the services of our executive officers or other key employees could impede the achievement of our
development  and  commercialization  objectives  and  seriously  harm  our  ability  to  successfully  implement  our  business
strategy. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of
time  because  of  the  limited  number  of  individuals  in  our  industry  with  the  breadth  of  skills  and  experience  required  to
successfully  develop,  gain  marketing  approval  of  and  commercialize  drugs.  Competition  to  hire  from  this  limited  pool  is
intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition
among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the
hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and
advisors, including scientific and clinical advisors, to assist us in formulating our

61

 
 
 
 
 
 
 
 
 
 
Table of Contents

development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and
may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we
are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited. 

We  expect  to  expand  our  development  and  regulatory  capabilities  and  implement  sales,  marketing  and
distribution capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our
operations.

As of December 31, 2018, we had 169 full-time and part-time employees. As we progress, we expect to experience
growth  in  the  number  of  our  employees  and  the  scope  of  our  operations,  particularly  in  the  areas  of  drug  development,
regulatory  affairs,  sales,  marketing  and  distribution.  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  the  limited  experience  of  our  management
team in managing a company with 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  our  management  and  business  development  resources.  Any  inability  to  manage  growth  could  delay  the
execution of our business plans or disrupt our operations.

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

We  are  exposed  to  the  risk  that  our  employees,  independent  contractors,  consultants,  commercial  collaborators,
principal investigators, CROs and vendors may engage in fraudulent conduct or other illegal activity. Misconduct by these
parties could include intentional, reckless and/or negligent conduct or disclosure of unauthorized activities to us that violates
FDA  regulations,  including  those  laws  requiring  the  reporting  of  true,  complete  and  accurate  information  to  the  FDA,
manufacturing  standards,  federal  and  state  health  care  laws  and  regulations,  and  laws  that  require  the  true,  complete  and
accurate  reporting  of  financial  information  or  data.  In  particular,  sales,  marketing  and  business  arrangements  in  the  health
care  industry  are  subject  to  extensive  laws  and  regulations  intended  to  prevent  fraud,  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  individually  identifiable  information,  including,  without  limitation,  information
obtained  in  the  course  of  clinical  trials,  which  could  result  in  regulatory  sanctions  and  serious  harm  to  our  reputation.  We
have adopted a code of business conduct and ethics, but it is not always possible to identify and deter misconduct, 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  be  in
compliance with such laws or regulations. 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  civil,  criminal  and  administrative  penalties,  including,  without  limitation,  damages,  fines,  disgorgement,
imprisonment, exclusion from participation in government health care programs, such as Medicare and Medicaid, additional
reporting  obligations  and  oversight  if  we  are  subject  to  a  corporate  integrity  agreement  or  other  agreement  to  resolve
allegations of non-compliance with these laws, and the curtailment or restructuring of our operations.

We may not realize the anticipated benefits of our acquisition of Confluence.

In  August  2017,  we  acquired  Confluence,  including  several  preclinical  drug  candidates  and  Confluence’s  contract
research  services  business.  Acquisitions  are  inherently  risky,  and  we  may  not  realize  the  anticipated  benefits  of  the
acquisition of Confluence.  Specifically, we are subject to the risks that:

·

·
·

we receive inadequate or unfavorable data from preclinical studies or clinical trials evaluating the acquired
preclinical drug candidates;
we fail to manage the complexities resulting from the larger combined company with distant business locations; and
we fail to maintain relationships with customers, suppliers and employees.

62

 
 
 
 
 
 
 
 
 
Table of Contents

If any of these events were to occur, our ability to achieve the anticipated benefits of the merger could be adversely
affected, or could reduce our future earnings or otherwise adversely affect our business and financial results and, as a result,
adversely affect the market price of our common stock.

We may not realize the anticipated benefits from our acquisition of RHOFADE. 

The success of our acquisition of RHOFADE will depend, in large part, on our ability to realize operating synergies

from combining RHOFADE with our portfolio of drug candidates and ESKATA. 

The failure to successfully integrate and manage the challenges presented by the integration process may result in
our failure to achieve some or all of the anticipated benefits of the acquisition. Potential difficulties that may be encountered
include the following:

·
·
·

·

·

complexities associated with managing an additional commercial-stage drug;
training our sales force to market both ESKATA and RHOFADE;
current and prospective employees may experience uncertainty regarding their future roles with our company, which
might adversely affect our ability to retain, recruit and motivate key personnel;
our due diligence processes in connection with the acquisition may fail to identify significant problems, risks,
liabilities or other shortcomings or challenges associated with the RHOFADE assets, including problems, risks,
liabilities or other shortcomings or challenges with respect to intellectual property, product quality and safety and
other known and unknown liabilities; and
performance shortfalls as a result of the diversion of management’s attention caused by completing the acquisition
and integrating RHOFADE.

If any of these events were to occur, our ability to maintain relationships with customers, suppliers and employees or
our  ability  to  achieve  the  anticipated  benefits  of  the  acquisition  could  be  adversely  affected,  or  could  reduce  our  future
earnings or otherwise adversely affect our business and financial results and, as a result, adversely affect the market price of
our common stock. 

Risks Related to Ownership of Our Common Stock

An active trading market for our common stock may not continue to develop or be sustained.

Prior to our initial public offering in October 2015, there was no public market for our common stock. Although our
common  stock  is  listed  on  The  Nasdaq  Global  Select  Market,  we  cannot  assure  you  that  an  active  trading  market  for  our
shares will continue to develop or be sustained. If an active market for our common stock does not continue to develop or is
not sustained, it may be difficult for investors in our common stock to sell shares without depressing the market price for the
shares or to sell the shares at all. 

The trading price of the shares of our common stock has been and is likely to continue to be volatile.

Since our initial public offering, our stock price has been and is likely to continue to be volatile. The stock market in
general  and  the  market  for  biotechnology  companies  in  particular  have  experienced  extreme  volatility  that  has  often  been
unrelated to the operating performance of particular companies. As a result of this volatility, investors may not be able to sell
their common stock at or above the price paid for the shares. The market price for our common stock may be influenced by
many factors, including:

·

·

·
·
·
·

the commencement, enrollment or results of any clinical trials we may conduct, or changes in the development
status of our drug candidates;
any delay in our regulatory filings for any of our drug candidates and any adverse development or perceived adverse
development with respect to the applicable regulatory authority’s review of such filings, including without limitation
the FDA’s issuance of a “refusal to file” letter or a request for additional information;
adverse results from, delays in or termination of clinical trials;
adverse regulatory decisions, including failure to receive marketing approval of our drug candidates;
unanticipated serious safety concerns related to the use of ESKATA, RHOFADE or any drug candidate;
changes in financial estimates by us or by any securities analysts who might cover our stock;

·

conditions or trends in our industry;
changes in the structure of health care payment systems;
changes in the market valuations of similar companies;
stock market price and volume fluctuations of comparable companies and, in particular, those that operate in the
biotechnology industry;
publication of research reports about us or our industry or positive or negative recommendations or withdrawal of
research coverage by securities analysts;
announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures;
announcements of investigations or regulatory scrutiny of our operations or lawsuits filed against us;
investors’ general perception of our company and our business;
recruitment or departure of key personnel;
overall performance of the equity markets;
trading volume of our common stock;
disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to
obtain patent protection for our technologies;
significant lawsuits, including patent or stockholder litigation;
general political and economic conditions; and
other events or factors, many of which are beyond our control.

In addition, in the past, stockholders have initiated class action lawsuits against pharmaceutical and biotechnology
companies following periods of volatility in the market prices of these companies’ stock. Such litigation, if instituted against
us, could cause us to incur substantial costs and divert management’s attention and resources from our business.

If equity research analysts do not publish research or reports, or publish unfavorable research or reports, about

us, our business or our market, our stock price and trading volume could decline.

The  trading  market  for  our  common  stock  is  influenced  by  the  research  and  reports  that  equity  research  analysts
publish  about  us  or  our  business,  our  market  and  our  competitors.  Equity  research  analysts  may  elect  not  to  initiate  or
continue to provide research coverage of our common stock, and such lack of research coverage may adversely affect the
market price of our common stock. Even if we have equity research analyst coverage, we will not have any control over the
analysts  or  the  content  and  opinions  included  in  their  reports.  The  price  of  our  stock  could  decline  if  one  or  more  equity
research  analysts  downgrade  our  stock  or  issue  other  unfavorable  commentary  or  research.  If  one  or  more  equity  research
analysts  ceases  coverage  of  our  company  or  fails  to  publish  reports  on  us  regularly,  demand  for  our  stock  could  decrease,
which in turn could cause our stock price or trading volume to decline. 

The  issuance  of  additional  stock  in  connection  with  financings,  acquisitions,  investments,  our  equity  incentive

plan or otherwise will dilute all other stockholders.

Our  certificate  of  incorporation  authorizes  us  to  issue  up  to  100,000,000  shares  of  common  stock  and  up  to
10,000,000  shares  of  preferred  stock  with  such  rights  and  preferences  as  may  be  determined  by  our  board  of  directors.
Subject  to  compliance  with  applicable  rules  and  regulations,  we  may  issue  our  shares  of  common  stock  or  securities
convertible  into  our  common  stock  from  time  to  time  in  connection  with  a  financing,  acquisition,  investment,  our  equity
incentive plan or otherwise. Any such issuance could result in substantial dilution to our existing stockholders and cause the
trading price of our common stock to decline. 

Sales of a substantial number of shares of our common stock into the market could cause the market price of our

common stock to drop significantly, even if our business is doing well.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. If our
stockholders sell, or the market perceives that our stockholders intend to sell, substantial amounts of our common stock in the
public market, the market price of our common stock could decline significantly.

In addition, we have filed registration statements on Form S-8 under the Securities Act registering the issuance of
shares  of  common  stock  subject  to  options  or  other  equity  awards  issued  or  reserved  for  future  issuance  under  our  equity
incentive plans. Shares registered under these registration statements are available for sale in the public market subject to

64

 
 
 
 
 
 
 
 
 
Table of Contents

vesting  arrangements  and  exercise  of  options,  and  the  restrictions  of  Rule  144  under  the  Securities  Act  in  the  case  of  our
affiliates.

Additionally,  certain  holders  of  shares  of  our  common  stock,  or  their  transferees,  have  rights,  subject  to  some
conditions,  to  require  us  to  file  one  or  more  registration  statements  covering  their  shares  or  to  include  their  shares  in
registration statements that we may file for ourselves or other stockholders. If we were to register the resale of these shares,
they could be freely sold in the public market. If these additional shares are sold, or if it is perceived that they will be sold, in
the public market, the trading price of our common stock could decline.

Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by our
stockholders to change our management and hinder efforts to acquire a controlling interest in us, and the market price of
our common stock may be lower as a result.

There  are  provisions  in  our  certificate  of  incorporation  and  bylaws  that  may  make  it  difficult  for  a  third  party  to
acquire, or attempt to acquire, control of our company, even if a change of control was considered favorable by some or all of
our stockholders. For example, our board of directors has the authority to issue up to 10,000,000 shares of preferred stock.
The  board  of  directors  can  fix  the  price,  rights,  preferences,  privileges,  and  restrictions  of  the  preferred  stock  without  any
further vote or action by our stockholders. The issuance of shares of preferred stock may delay or prevent a change of control
transaction. As a result, the market price of our common stock and the voting and other rights of our stockholders may be
adversely affected. An issuance of shares of preferred stock may result in the loss of voting control to other stockholders.

Our charter documents also contain other provisions that could have an anti-takeover effect, including:

·
·
·
·
·

only one of our three classes of directors is elected each year;
stockholders are not entitled to remove directors other than by a 66 % vote and only for cause;
stockholders are not permitted to take actions by written consent;
stockholders cannot call a special meeting of stockholders; and
stockholders must give advance notice to nominate directors or submit proposals for consideration at stockholder
meetings.

2/3

In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law,
which  regulates  corporate  acquisitions  by  prohibiting  Delaware  corporations  from  engaging  in  specified  business
combinations  with  particular  stockholders  of  those  companies.  These  provisions  could  discourage  potential  acquisition
proposals and could delay or prevent a change of control transaction. They could also have the effect of discouraging others
from making tender offers for our common stock, including transactions that may be in your best interests. These provisions
may also prevent changes in our management or limit the price that investors are willing to pay for our stock.

Concentration of ownership of our common stock among our existing executive officers, directors and principal

stockholders may prevent new investors from influencing significant corporate decisions.

Our  executive  officers,  directors  and  current  beneficial  owners  of  5%  or  more  of  our  common  stock  and  their
respective affiliates beneficially own a substantial portion of our common stock. As a result, these persons, acting together,
would  be  able  to  significantly  influence  all  matters  requiring  stockholder  approval,  including  the  election  and  removal  of
directors, any merger, consolidation, sale of all or substantially all of our assets, or other significant corporate transactions.
The interests of this group of stockholders may not coincide with our interests or the interests of other stockholders.

We are an “emerging growth company” and, as a result of the reduced disclosure and governance requirements

applicable to emerging growth companies, our common stock may be less attractive to investors.

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS
Act,  and  we  intend  to  take  advantage  of  some  of  the  exemptions  from  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 this report;
not being required to comply with the auditor attestation requirements in the assessment of our internal control over
financial reporting;
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, proxy statements and
registration statements; and
not being required to hold a nonbinding advisory vote 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 will 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 may take advantage of these reporting exemptions until we are no longer
an emerging growth company. We will remain an emerging growth company until the earlier of (1) December 31, 2020, (2)
the last day of the fiscal year in which we have total annual gross revenue of at least $1.07 billion, (3) the last day of the
fiscal year in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is
held by non-affiliates exceeds $700 million as of the prior June 30th and (4) any date on which we have issued more than
$1.0 billion in non-convertible debt during the prior three-year period.

We also qualify as a “smaller reporting company” as defined in Rule 12b-2 of the Exchange Act, and so long as we

remain a smaller reporting company, we benefit from some of the same scaled disclosure requirements.

Under Section 107(b) of the JOBS Act, emerging growth companies can 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,  we  will  be  subject  to  the  same  new  or  revised
accounting standards as other public companies that are not emerging growth companies.

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements

on a timely basis could be impaired.

We  are  subject  to  the  reporting  requirements  of  the  Exchange  Act,  the  Sarbanes-Oxley  Act  and  the  rules  and
regulations of the stock market on which our common stock is listed. The Sarbanes-Oxley Act requires, among other things,
that  we  maintain  effective  disclosure  controls  and  procedures  and  internal  control  over  financial  reporting,  and  perform
system and process evaluation and testing of our internal control over financial reporting to allow management to report on
the  effectiveness  of  our  internal  control  over  financial  reporting.  This  requires  that  we  incur  substantial  additional
professional  fees  and  internal  costs  to  expand  our  accounting  and  finance  functions  and  that  we  expend  significant
management efforts.

We may identify weaknesses in our system of internal financial and accounting controls and procedures that could
result in a material misstatement of our consolidated financial statements. Our internal control over financial reporting will
not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only
reasonable, not absolute, assurance that the control system’s objectives will be met. 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.

66

 
 
 
 
 
 
 
 
 
 
Table of Contents

If  we  are  unable  to  maintain  proper  and  effective  internal  controls,  we  may  not  be  able  to  produce  timely  and
accurate financial statements, and we may conclude that our internal control over financial reporting is not effective. 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.

We might not be able to utilize a significant portion of our net operating loss carryforwards and research and

development tax credit carryforwards.

As of December 31, 2018, we had federal and state net operating loss carryforwards of $199.5 million and $212.4
million,  respectively,  which  will  begin  to  expire  in  2032.    As  of  December  31,  2018,  we  also  had  federal  research  and
development tax credit carryforwards of $4.9 million which begin to expire in 2032, and state research and development tax
credit  carryforwards  of  $0.1  million  which  begin  to  expire  in  2022.  These  net  operating  loss  and  tax  credit  carryforwards
could expire unused and be unavailable to offset future income tax liabilities. In addition, under Section 382 of the Internal
Revenue  Code  of  1986,  as  amended,  and  corresponding  provisions  of  state  law,  if  a  corporation  undergoes  an  “ownership
change,” which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period,
the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its
post-change income may be limited.  We have completed an analysis under Section 382 for net operating loss carryforwards
generated from July 13, 2012 through December 31, 2016.  Although we have experienced Section 382 ownership changes
since 2012, we have concluded that we should have sufficient ability to utilize net operating loss carryforwards accumulated
during the periods tested.  We have not yet determined if a Section 382 ownership change has occurred during the year ended
December 31, 2017, or for Confluence prior to the acquisition.  In addition, we may experience ownership changes in the
future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If we determine
that an ownership change has occurred and our ability to use our historical net operating loss and tax credit carryforwards is
materially limited, it would harm our future operating results by effectively increasing our future tax obligations. 

The 2017 comprehensive tax reform bill could adversely affect our business and financial condition.

On  December  22,  2017,  the  Tax  Cuts  and  Jobs  Act  of  2017  was  signed  into  law  which  significantly  revised  the
Internal Revenue Code of 1986, as amended.  The federal income tax legislation, among other things, contained significant
changes to corporate taxation, including reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of
21%, limitation of the tax deduction for interest expense to 30% of adjusted earnings (except for certain small businesses),
limitation of the deduction for net operating losses to 80% of current year taxable income and elimination of net operating
loss carrybacks, one time taxation of offshore earnings at reduced rates regardless of whether they are repatriated, elimination
of U.S. tax on foreign earnings (subject to certain important exceptions), immediate deductions for certain new investments
instead  of  deductions  for  depreciation  expense  over  time,  and  modifying  or  repealing  many  business  deductions  and
credits.  Notwithstanding the reduction in the corporate income tax rate, the overall impact of the changes to the federal tax
law is uncertain and our business and financial condition could be adversely affected.  In addition, it is uncertain how various
states will respond to the changes in the federal tax law.  The impact of this tax reform on holders of our common stock is
also uncertain and could be adverse.  We urge our stockholders to consult with their legal and tax advisors with respect to this
legislation and the potential tax consequences of investing in or holding our common stock.

We have broad discretion in the use of proceeds from our equity financing transactions and may invest or spend

the proceeds in ways with which you do not agree and in ways that may not increase the value of your investment.

We have broad discretion over the use of proceeds from our equity financing transactions over the last several years.
You may not agree with our decisions, and our use of the proceeds may not yield any return on your investment. We expect to
use the net proceeds from those transactions to conduct commercial activities for ESKATA and RHOFADE, and to fund the
continued research and development of our drug candidates, as well as for working capital and general corporate purposes.
Our failure to apply the net proceeds effectively could compromise our ability to pursue our strategy and we might not be
able to yield a significant return, if any, on our investment of these net proceeds. Stockholders will not have the opportunity
to influence our decisions on how to use these net proceeds.

We  do  not  anticipate  paying  any  cash  dividends  on  our  common  stock  in  the  foreseeable  future  and  our  stock

may not appreciate in value.

We have not declared or paid cash dividends on our common stock to date. We currently intend to retain our future
earnings, if any, to fund the development and growth of our business. In addition, the terms of our current loan agreement
with Oxford prohibits us, and future debt agreements may also preclude us, from paying dividends. There is no guarantee that
shares of our common stock will appreciate in value or that the price at which our stockholders have purchased their shares
will be able to be maintained.

We will incur increased costs and demands upon management as a result of being a public company.

As a public company listed in the United States, we have begun, and will continue, particularly after we cease to be
an “emerging growth company,” to incur significant additional legal, accounting and other costs. These additional costs could
negatively affect our financial results. In addition, changing laws, regulations and standards relating to corporate governance
and public disclosure, including regulations implemented by the SEC and The Nasdaq Stock Market, may increase legal and
financial compliance costs and make some activities more time-consuming. These laws, regulations and standards are subject
to varying interpretations and, as a result, their application in practice may evolve over time as new guidance is provided by
regulatory and governing bodies. We intend to invest resources to comply with evolving laws, regulations and standards, and
this  investment  may  result  in  increased  general  and  administrative  expenses  and  a  diversion  of  management’s  time  and
attention from revenue-generating activities to compliance activities. If notwithstanding our efforts to comply with new laws,
regulations and standards, we fail to comply, regulatory authorities may initiate legal proceedings against us and our business
may be harmed.

Failure  to  comply  with  these  rules  might  also  make  it  more  difficult  for  us  to  obtain  some  types  of  insurance,
including  director  and  officer  liability  insurance,  and  we  might  be  forced  to  accept  reduced  policy  limits  and  coverage  or
incur substantially higher costs to obtain the same or similar coverage. The impact of these events could also make it more
difficult  for  us  to  attract  and  retain  qualified  persons  to  serve  on  our  board  of  directors,  on  committees  of  our  board  of
directors or as members of senior management.

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

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware
is the exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim for
breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action
asserting  a  claim  arising  pursuant  to  any  provision  of  the  Delaware  General  Corporation  Law,  our  amended  and  restated
certificate of incorporation or our amended and restated bylaws or (iv) any action asserting a claim governed by the internal
affairs doctrine. The choice of 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 such lawsuits against
us  and  our  directors,  officers  and  other  employees.  Alternatively,  if  a  court  were  to  find  the  choice  of  forum  provision
contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may
incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business
and financial condition.

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

You  should  read  the  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  in
conjunction with the consolidated financial statements and the related notes to those statements included later in this Annual
Report.  In  addition  to  historical  financial  information,  the  following  discussion  contains  forward‑looking  statements  that
reflect our plans, estimates, beliefs and expectations that involve risks and uncertainties. Our actual results and the timing of
events  could  differ  materially  from  those  discussed  in  these  forward‑looking  statements.  Factors  that  could  cause  or
contribute to these differences include those discussed below and elsewhere in this Annual Report, particularly in “Item 1A.
Risk Factors” and “Special Note Regarding Forward‑Looking Statements.”

Overview

We  are  a  physician-led  biopharmaceutical  company  focused  on  dermatological  and  immuno-inflammatory

diseases.  We have two commercial products and a diverse pipeline of drug candidates.

Our  first  commercial  product,  ESKATA  (hydrogen  peroxide)  topical  solution,  40%  (w/w),  or  ESKATA,  is  a
proprietary formulation of high-concentration hydrogen peroxide topical solution which was approved by the U.S. Food and
Drug Administration, or FDA, in December 2017 as an office-based prescription treatment for raised seborrheic keratosis, or
SK, a common non-malignant skin tumor.  We launched ESKATA in the United States in May 2018.  We also submitted a
Marketing Authorization Application, or MAA, for ESKATA in select countries in the European Union, Norway and Iceland
in July 2017 using a decentralized procedure.  In February 2019, we received approval from the Swedish Medical Products
Agency to market ESKATA (hydrogen peroxide) cutaneous solution, 685 mg for the treatment in adults of SKs that are not
pedunculated  and  have  up  to  a  maximum  diameter  of  15  millimeters  each.    We  have  also  received  approval  to  market
ESKATA in the United Kingdom, Iceland and Belgium.

In  November  2018,  we  acquired  RHOFADE  (oxymetazoline  hydrochloride)  cream,  1%,  or  RHOFADE,  which
includes an exclusive license to certain intellectual property for RHOFADE, as well as additional intellectual property, from
Allergan  Sales,  LLC,  or  Allergan.    RHOFADE  was  approved  by  the  FDA  in  January  2017  for  the  topical  treatment  of
persistent facial erythema (redness) associated with rosacea in adults. Persistent facial redness is the most common sign of
rosacea in most skin types.

We continue to develop our sales, marketing and product distribution capabilities for ESKATA and RHOFADE in
order to support our commercialization efforts in the United States.  We plan to continue to deploy sales representatives in
approximately  50  territories  in  the  United  States  which  we  believe  will  allow  us  to  reach  the  health  care  providers  in  the
United States with the highest potential for prescribing ESKATA and RHOFADE to their patients.

We are also developing another high-concentration formulation of hydrogen peroxide, A-101 45% Topical Solution,
as a prescription treatment for common warts, also known as verruca vulgaris.  On an annual basis, approximately 2.0 million
people in the United States are diagnosed with common warts.

Additionally,  in  2015,  we  in-licensed  exclusive,  worldwide  rights  from  Rigel  Pharmaceuticals,  Inc.,  or  Rigel,  to
certain inhibitors of the Janus kinase, or JAK, family of enzymes, for specified dermatological conditions, including alopecia
areata, or AA.  AA is an autoimmune dermatologic condition typically characterized by patchy non-scarring hair loss on the
scalp and body.  More severe forms of AA include total scalp hair loss, known as alopecia totalis, or AT, and total hair loss on
the scalp and body, known as alopecia universalis, or AU. We are also developing these JAK inhibitors for the treatment of
vitiligo, androgenetic alopecia, or AGA, also known as male or female pattern baldness, and atopic dermatitis.    

In  2016,  in  connection  with  the  acquisition  of  Vixen  Pharmaceuticals,  Inc.,  or  Vixen,  we  acquired  additional
intellectual property rights for the development and commercialization of certain JAK inhibitors for specified dermatological
conditions.    We  intend  to  continue  to  in-license  or  acquire  additional  drug  candidates  and  technologies  to  build  a  fully
integrated biopharmaceutical company.

In  2017,  we  acquired  Confluence  Life  Sciences,  Inc.  (now  known  as  Aclaris  Life  Sciences,  Inc.),  or
Confluence.  The acquisition of Confluence added small molecule drug discovery and preclinical development capabilities
that  allowed  us  to  bring  early-stage  research  and  development  activities  in-house  that  we  previously  outsourced  to  third
parties.  We intend to leverage the proprietary KINect drug discovery platform to identify potential drug candidates that we
may

71

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

develop  independently  or  with  partners.  We  also  acquired  several  preclinical  drug  candidates,  including  additional  topical
JAK  inhibitors  known  as  soft-JAK  inhibitors,  inhibitors  of  the  MK-2  signaling  pathway  and  inhibitors  of  interleukin-2-
inducible  T  cell  kinase,  or  ITK.  Soft-JAK  inhibitors  may  be  topically  applied  and  active  in  the  skin,  but  will  be  rapidly
metabolized and inactivated when they enter the bloodstream, which may result in significantly reduced systemic exposure.
We also earn revenue from Confluence’s provision of contract research services to third parties. 

Since  our  inception,  we  have  incurred  significant  operating  losses.    Our  net  loss  was  $132.7  million  for  the  year
ended December 31, 2018 and $68.5 million for the year ended December 31, 2017.  As of December 31, 2018, we had an
accumulated  deficit  of  $292.2  million.    We  expect  to  incur  significant  expenses  and  operating  losses  related  to  product
manufacturing, marketing, sales and distribution over the next several years as we continue to commercialize ESKATA and
RHOFADE.    In  addition,  ESKATA  and  RHOFADE,  and  our  drug  candidates  if  approved,  may  not  achieve  commercial
success.  We also expect to incur significant expenses and operating losses for the foreseeable future as we advance our drug
candidates from discovery through preclinical development and clinical trials. In addition, if we obtain marketing approval
for any of our drug candidates, we expect to incur significant commercialization expenses related to product manufacturing,
marketing, sales and distribution.  We may also incur expenses in connection with the in-license or acquisition of additional
drug candidates. Furthermore, we have incurred and expect to continue to incur significant costs associated with operating as
a public company, including legal, accounting, investor relations and other expenses.  As a result, we will need substantial
additional funding to support our continuing operations and pursue our growth strategy. 

We have historically financed our operations primarily with sales of our convertible preferred stock, as well as net
proceeds from our initial public offering, or IPO, in October 2015, subsequent public offerings, and a private placement of
our common stock.    Until such time as we can generate significant revenue from product sales, if ever, we expect to finance
our  operations  through  the  sale  of  equity,  debt  financings  or  other  capital  sources,  including  potential  collaborations  with
other  companies  or  other  strategic  transactions.    We  may  be  unable  to  raise  additional  funds  or  enter  into  such  other
agreements or arrangements when needed on commercially 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  one  or  more  of  our  products  or  drug  candidates  or  delay  our  pursuit  of  potential  in-licenses  or
acquisitions. 

License Agreement with Rigel

In  August  2015,  we  entered  into  an  exclusive,  worldwide  license  and  collaboration  agreement  with  Rigel
Pharmaceuticals,  Inc.,  or  Rigel,  for  the  development  and  commercialization  of  products  containing  two  specified  JAK
inhibitors, ATI-501 and ATI-502, or the Rigel License Agreement.  Under this agreement, we intend to develop these JAK
inhibitors for the treatment of AA and other dermatological conditions. We paid Rigel an upfront nonrefundable payment of
$8.0 million in September 2015. In addition, we have agreed to make aggregate payments of up to $80.0 million upon the
achievement of specified pre-commercialization milestones, such as clinical trials and regulatory approvals. Further, we have
agreed to pay up to an additional $10.0 million to Rigel upon the achievement of a second set of development milestones.
With  respect  to  any  products  we  commercialize  under  the  Rigel  License  Agreement,  we  will  pay  Rigel  quarterly  tiered
royalties on our annual net sales of each product at a high single digit percentage of annual net sales, subject to specified
reductions until the date that all of the patent rights for that product have expired, as determined on a country-by-country and
product-by-product basis or, in specified countries under specified circumstances, 10 years from the first commercial sale of
such product.

The Rigel License Agreement terminates on the date of expiration of all royalty obligations unless earlier terminated
by either party for a material breach. We may also terminate the Rigel License Agreement without cause at any time upon
advance  written  notice  to  Rigel.  Rigel,  after  consultation  with  us,  will  be  responsible  for  maintaining  and  prosecuting  the
patent rights, and we will have final decision-making authority regarding such patent rights for a product in the United States
and the European Union. To the extent that we jointly develop intellectual property, we will confer and decide which party
will be responsible for filing, prosecuting and maintaining those patent rights. The Rigel License Agreement also establishes
a joint steering committee composed of an equal number of representatives for each party, which will monitor progress in the
development of products.

Stock Purchase Agreement with Vixen Pharmaceuticals, Inc. and License Agreement with Columbia University

In March 2016, we entered into a stock purchase agreement, or the Vixen Agreement, with Vixen, and JAK1, LLC,
JAK2,  LLC  and  JAK3,  LLC,  or  together,  the  Selling  Stockholders,  and  Shareholder  Representative  Services  LLC  as  the
representative of the Selling Stockholders.  Pursuant to the Vixen Agreement, we acquired all shares of Vixen’s capital stock
from the Selling Stockholders, or the Vixen Acquisition. Following the Vixen Acquisition, Vixen became a wholly-owned
subsidiary of us. Pursuant to the Vixen Agreement, we paid $0.6 million upfront and issued an aggregate of 159,420 shares of
our common stock to the Selling Stockholders. We are obligated to make annual payments of $0.1 million through March
2022, with such amounts being creditable against specified future payments that may be paid under the Vixen Agreement. 

Under  the  Vixen  Agreement  we  are  obligated  to  make  aggregate  payments  of  up  to  $18.0  million  to  the  Selling
Stockholders upon the achievement of specified pre-commercialization milestones for three products in the United States, the
European Union and Japan, and aggregate payments of up to $22.5 million upon the achievement of specified commercial
milestones.  With  respect  to  any  commercialized  products  covered  by  the  Vixen  Agreement,  we  are  obligated  to  pay  low
single-digit royalties on net sales, subject to specified reductions, limitations and other adjustments, until the date that all of
the patent rights for that product have expired, as determined on a country-by-country and product-by-product basis or, in
specified  circumstances,  ten  years  from  the  first  commercial  sale  of  such  product.  If  we  sublicense  any  of  Vixen’s  patent
rights and know-how acquired pursuant to the Vixen Agreement, we will be obligated to pay a portion of any consideration
we receive from such sublicenses in specified circumstances. 

As a result of the Vixen Acquisition, we became party to the Exclusive License Agreement, by and between Vixen
and  the  Trustees  of  Columbia  University  in  the  City  of  New  York,  or  Columbia,  dated  as  of  December  31,  2015,  or,  as
amended, the Columbia License Agreement.  Under the Columbia License Agreement, we are obligated to pay Columbia an
annual  license  fee  of  $10,000  subject  to  specified  adjustments  for  patent  expenses  incurred  by  Columbia  and  creditable
against  any  royalties  that  may  be  paid  under  the  Columbia  License  Agreement.  We  are  also  obligated  to  pay  up  to  an
aggregate of $11.6 million upon the achievement of specified commercial milestones, including specified levels of net sales
of products covered by Columbia patent rights and/or know-how, and royalties at a sub-single-digit percentage of annual net
sales of products covered by Columbia patent rights and/or know-how, subject to specified adjustments. If we sublicense any
of Columbia’s patent rights and know-how acquired pursuant to the Columbia License Agreement, we will be obligated to
pay Columbia a portion of any consideration received from such sublicenses in specified circumstances.  The royalties, as
determined on a country-by-country and product-by-product basis, are payable until the date that all of the patent rights for
that  product  have  expired,  the  expiration  of  any  market  exclusivity  period  granted  by  a  regulatory  body  or,  in  specified
circumstances, ten years from the first commercial sale of such product.  The Columbia License Agreement terminates on the
date of expiration of all royalty obligations thereunder unless earlier terminated by either party for a material breach, subject
to a specified cure period. We may also terminate the Columbia License Agreement without cause at any time upon advance
written notice to Columbia. 

Agreement and Plan of Merger with Confluence

In August 2017, we entered into an Agreement and Plan of Merger, or the Confluence Agreement, with Confluence,
Aclaris Life Sciences, Inc., our wholly-owned subsidiary, or Merger Sub, and Fortis Advisors LLC, as representative of the
equity holders of Confluence.  Pursuant to the terms of the Confluence Agreement, the Merger Sub merged with and into
Confluence, with Confluence surviving as our wholly-owned subsidiary.  We paid $10.3 million in cash and issued 349,527
shares of our common stock with a fair value of $9.7 million to the Confluence equity holders. 

In November 2018, we achieved a development milestone specified in the Confluence Agreement.  The milestone
payment to the former Confluence equity holders was comprised of $2.5 million in cash and 253,208 shares of our common
stock  with  a  fair  value  of  $2.2  million.   We  also  agreed  to  pay  the  former  Confluence  equity  holders  aggregate  additional
contingent consideration of up to $75.0 million, based upon the achievement of certain regulatory and commercial milestones
set forth in the Confluence Agreement.  In addition, we have agreed to pay the former Confluence equity holders specified
future  royalty  payments  calculated  as  a  low  single-digit  percentage  of  annual  net  sales,  subject  to  specified  reductions,
limitations and other adjustments, until the date that all of the patent rights for that product have expired, as determined on a
country-by-country and product-by-product basis or, in specified circumstances, ten years from the first commercial sale of
such product.  In addition, if we sell, license or transfer any of the intellectual property acquired from Confluence pursuant to
the Confluence Agreement to a third party, we will be obligated to pay the former

73

 
 
 
 
 
 
 
 
Table of Contents

Confluence equity holders a portion of any incremental consideration (in excess of the development and milestone payments
described above) that we receive from such sale, license or transfer in specified circumstances. 

License, Development and Commercialization Agreement with Cipher Pharmaceuticals Inc.

In April 2018, we entered into an exclusive license agreement with Cipher Pharmaceuticals Inc., or Cipher, for the
rights to obtain regulatory approval of and commercialize A-101 40% Topical Solution, which we market under the brand
name ESKATA in the United States, in Canada for the treatment of SK, or the Cipher License Agreement.  Under the Cipher
License Agreement, Cipher is responsible for obtaining marketing approval in Canada for A-101 40% Topical Solution.  We
will supply Cipher with finished product, and, if regulatory approval is obtained, Cipher will be responsible for distribution
and  commercialization  of  A-101  40%  Topical  Solution  in  Canada.    Additionally,  Cipher  is  responsible  for  all  expenses
related to regulatory and commercial activities for A-101 40% Topical Solution in Canada.  We received an upfront payment
of  $1.0  million  upon  signing  of  the  Cipher  License  Agreement  and  $0.5  million  upon  the  achievement  of  a  specified
regulatory milestone.  Pursuant to the Cipher License Agreement, we can earn a remaining payment of $0.5 million upon the
achievement of a specified regulatory milestone, and aggregate payments of $1.75 million upon the achievement of specified
commercial milestones.  Cipher will also be required to pay us a low double-digit percentage royalty on net sales of A-101
40%  Topical  Solution  in  Canada.    The  term  of  the  Cipher  License  Agreement  expires  on  the  later  of  the  expiration  of
applicable  patents  in  Canada  or  the  15   anniversary  of  the  first  commercial  sale  of  licensed  product  in  Canada.    Cipher
submitted a New Drug Submission for A-101 40% Topical Solution for the treatment of raised SKs, which was accepted for
review by Health Canada in December 2018.

th

Asset Purchase Agreement with Allergan

In  November  2018,  we  completed  the  acquisition  of  RHOFADE,  which  includes  an  exclusive  license  to  certain
intellectual property for RHOFADE, as well as additional intellectual property, from Allergan, pursuant to the Asset Purchase
Agreement dated as of October 15, 2018, or as amended, the Asset Purchase Agreement.    

At the closing of the acquisition, we paid total cash consideration of $66.1 million, consisting of $59.6 million paid
to Allergan and $6.5 million placed in escrow. We have also agreed to pay Allergan a one-time payment of $5.0 million upon
the  achievement  of  a  specified  development  milestone  related  to  the  potential  development  of  an  additional  dermatology
product.  In addition, we have agreed to pay Allergan specified royalty payments, ranging from a mid-single digit percentage
to  a  mid-teen  percentage  of  net  sales,  subject  to  specified  reductions,  limitations  and  other  adjustments,  on  a  country-by-
country basis until the date that the patent rights related to a particular product, such as RHOFADE, have expired or, if later,
November 30, 2028. In addition, we have agreed to assume the obligation to pay specified royalties and milestone payments
under  agreements  with  Aspect  Pharmaceuticals,  LLC  and  Vicept  Therapeutics,  Inc.  Members  of  our  management  team,
including Neal Walker, Frank Ruffo, Christopher Powala and Stuart Shanler, as well as Stephen Tullman, the chairman of our
board of directors, are former stockholders of Vicept Therapeutics, Inc., and Dr. Shanler is also a current member of Aspect
Pharmaceuticals, LLC. In their capacities as current or former holders of equity interests in these entities, these individuals
may be entitled to receive a portion of the potential future payments payable by us.  We incurred an aggregate expense of
approximately $0.2 million and $0 related to royalty payments under these agreements during the years ended December 31,
2018 and 2017, respectively. 

RHOFADE  was  approved  by  the  FDA  in  January  2017  for  the  topical  treatment  of  persistent  facial  erythema
(redness) associated  with  rosacea  in  adults,  and  the  product  became  commercially  available  in  the  United  States  in  May
2017. 

Other Third-Party Agreements

Under  an  assignment  agreement,  pursuant  to  which  we  acquired  intellectual  property,  we  have  agreed  to  pay
royalties  on  sales  of  ESKATA,  or  other  related  products,  at  rates  ranging  in  low  single-digit  percentages  of  net  sales,  as
defined  in  the  agreement.    Under  this  assignment  agreement,  we  paid  $0.2  million  in  connection  with  a  specified
development milestone, and there are no remaining milestone payment obligations. 

74

 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

In connection with the assignment agreement, we also entered into a finder’s services agreement under which we
have  made  aggregate  milestone  payments  of  $3.0  million  upon  the  achievement  of  specified  pre-commercialization
milestones, such as clinical trials and regulatory approvals, and commercial milestones as described in the agreement.  We
have  also  agreed  to  make  an  additional  payment  of  $3.0  million  upon  the  achievement  of  a  specified  commercial
milestone.  In addition, we have agreed to pay royalties on sales of ESKATA, or other related products, at a low single-digit
percentage of net sales, as defined in the agreement. 

Components of Our Results of Operations

Revenue

Product Sales

We promote ESKATA and RHOFADE through our sales force which we believe will allow us to reach the health

care providers in the United States with the highest potential for prescribing ESKATA and RHOFADE to their patients. 

We  sell  ESKATA  to  one  wholesaler,  McKesson  Specialty  Care  Distribution,  or  McKesson,  which  in  turn  resells
ESKATA to health care providers.  We have also entered into agreements with two group purchasing organizations, or GPOs,
and may enter into additional agreements with other GPOs and corporate accounts that provide for administrative fees and
discounted pricing in the form of volume-based rebates and chargebacks.  We have no sales of ESKATA in countries outside
of the United States. 

We began commercializing RHOFADE in the United States in December 2018.  We currently rely on Allergan to
distribute  RHOFADE  on  our  behalf  pursuant  to  the  terms  of  a  transition  services  agreement  while  we  develop  our  sales,
marketing  and  distribution  capabilities  to  support  the  commercialization  of  RHOFADE  in  the  United  States.    We  sell
RHOFADE  to  wholesalers  in  the  United  States,  which,  in  turn,  distribute  it  to  pharmacies  that  will  ultimately  fill  patient
prescriptions.    We  may  also  enter  into  arrangements  with  health  care  providers,  pharmacy  benefit  managers,  third-party
payors, and GPOs which provide for government mandated and/or privately negotiated rebates, chargebacks, and discounts,
with respect to the purchase of RHOFADE.  We have no sales of RHOFADE in countries outside of the United States.  

Contract Research

We  earn  revenue  from  the  provision  of  laboratory  services  to  clients  through  Confluence,  our  wholly-owned
subsidiary.  Contract research revenue is generally evidenced by contracts with clients which are on an agreed upon fixed-
price, fee-for-service basis and are generally billed on a monthly basis in arrears for services rendered. 

We have also received revenue from grants under the Small Business Innovation Research program of the National
Institutes of Health, or NIH.  During the year ended December 31, 2018, we had two active grants from NIH related to early-
stage research.  As of December 31, 2018, there were no remaining funds available to us under the grants.

Cost of Revenue

Cost of revenue consists of the cost of manufacturing the finished product forms of ESKATA and RHOFADE, as
well as costs incurred in connection with the provision of contract research services to our clients through Confluence.  Cost
of revenue primarily includes:

Product sales:

·
·
·
·
·
·
·
·
·
·

third-party cost of manufacturing and assembly of finished product forms of ESKATA and RHOFADE;
depreciation of manufacturing equipment;
product release and stability testing;
warehousing and insurance costs;
transition service costs payable to Allergan;
royalty payments;
Prescription Drug User Fee Act, or PDUFA, fees;
non-cash charge to adjust the carrying-value of inventory to net realizable value;
non-cash charge related to the fair value step-up of acquired RHOFADE inventory; and
non-cash amortization of the intangible asset related to RHOFADE intellectual property.

Contract research:

·
·
·
·
·

employee-related expenses, which include salaries, benefits and stock-based compensation;
outsourced professional scientific services;
depreciation of laboratory equipment;
facility-related costs; and
laboratory materials and supplies used to support the services provided.

Research and Development Expenses

Research and development expenses consist of expenses incurred in connection with the discovery and development

of our drug candidates. These expenses primarily include:

·

expenses incurred under agreements with contract research organizations, or CROs, as well as investigative
sites and consultants that conduct our clinical trials and preclinical studies;

· manufacturing scale-up expenses and the cost of acquiring and manufacturing preclinical and clinical trial

materials and commercial materials, including manufacturing validation batches;
outsourced professional scientific development services;

·
· medical affairs-related expenses;
·
·
·

employee-related expenses, which include salaries, benefits and stock-based compensation;
depreciation of manufacturing equipment;
payments made under agreements with third parties under which we have acquired or licensed intellectual
property;
expenses relating to regulatory activities, including filing fees paid to regulatory agencies;
laboratory materials and supplies used to support our research activities; and
non-cash charges for changes in the fair value of contingent consideration related to the acquisition of
Confluence.

·
·
·

Research and development activities are central to our business model.  Drug candidates in later stages of clinical
development generally have higher development costs than those in earlier stages of clinical development, primarily due to
the  increased  size  and  duration  of  later-stage  clinical  trials.  We  expect  our  research  and  development  expenses  to  increase
significantly  over  the  next  several  years  as  we  increase  personnel  costs,  including  stock-based  compensation,  continue  to
conduct  clinical  trials  of  A-101  45%  Topical  Solution  for  the  treatment  of  common  warts,  and  conduct  clinical  trials  and
prepare regulatory filings for our other drug candidates.  We expense research and development costs as incurred.  Our direct
research and development expenses primarily consist of external costs including fees paid to CROs, consultants, investigator
sites, regulatory agencies and third parties that manufacture our preclinical and clinical trial materials, and are

76

 
 
 
 
 
 
 
 
 
 
Table of Contents

tracked on a program-by-program basis.  We do not allocate personnel costs, facilities or other indirect expenses, to specific
research and development programs. 

The successful development of our drug candidates is highly uncertain. At this time, we cannot reasonably estimate
or know the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of, or
when,  if  ever,  material  net  cash  inflows  may  commence  from  any  of  our  drug  candidates.  This  uncertainty  is  due  to  the
numerous risks and uncertainties associated with the duration and cost of clinical trials, which vary significantly over the life
of a project as a result of many factors, including:

·
·
·
·
·
·

the number of clinical sites included in the trials;
the length of time required to enroll suitable patients;
the number of patients that ultimately participate in the trials;
the number of doses subjects receive;
the duration of subject follow-up; and
the results of our clinical trials.

Our expenditures are subject to additional uncertainties, including the terms and timing of marketing approvals, and
the expense of filing, prosecuting, defending and enforcing any patent claims or other intellectual property rights. We may
never succeed in achieving marketing approval for any of our drug candidates. We may obtain unexpected results from our
clinical  trials.  We  may  elect  to  discontinue,  delay  or  modify  clinical  trials  of  some  drug  candidates  or  focus  on  others.  A
change in the outcome of any of these variables with respect to the development of a drug candidate could mean a significant
change  in  the  costs  and  timing  associated  with  the  development  of  that  drug  candidate.  For  example,  if  the  FDA  or  other
regulatory  authorities  were  to  require  us  to  conduct  clinical  trials  beyond  those  that  we  currently  anticipate,  or  if  we
experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional
financial resources and time on the completion of clinical development.

Sales and Marketing Expenses

Sales and marketing expenses include salaries and related costs for our field sales force, as well as personnel in our
marketing and sales operations functions, including stock-based compensation, travel expenses, expenses related to leasing a
fleet of vehicles for our field-based sales force, and recruiting expenses.  Sales and marketing expenses also include costs of
content  development,  advertising,  sponsorships  and  attendance  at  dermatology  conferences,  and  costs  incurred  under  the
transition services agreement with Allergan. 

Additionally,  we  anticipate  incurring  significant  sales  and  marketing  expenses  as  we  continue  to  commercialize

ESKATA and RHOFADE in the United States.

General and Administrative Expenses

General  and  administrative  expenses  consist  principally  of  salaries  and  related  costs  for  personnel  in  executive,
administrative,  finance,  investor  relations  and  legal  functions,  including  stock-based  compensation,  travel  expenses  and
recruiting  expenses.    General  and  administrative  expenses  also  include  facility-related  costs,  patent  filing  and  prosecution
costs,  professional  fees  for  legal,  auditing  and  tax  services,  insurance  costs,  costs  incurred  under  the  transition  services
agreement  with  Allergan,  as  well  as  payments  made  under  a  terminated  related  party  sublease  agreement  and  milestone
payments under our finder’s services agreement.  We anticipate that our general and administrative expenses will continue to
increase  as  a  result  of  increased  personnel  costs,  including  stock-based  compensation,  expanded  infrastructure  and  higher
consulting,  legal  and  tax-related  services  associated  with  maintaining  compliance  with  Nasdaq  and  SEC  requirements,
accounting  and  investor  relations  costs,  and  director  and  officer  insurance  premiums  associated  with  being  a  public
company. 

Other Income, net

Other income, net consists of interest earned on our cash, cash equivalents and marketable securities, interest

expense, and gains and losses on transactions denominated in foreign currencies.

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in
the  United  States.  The  preparation  of  our  consolidated  financial  statements  and  related  disclosures  requires  us  to  make
estimates  and  judgments  that  affect  the  reported  amounts  of  assets  and  liabilities,  disclosure  of  contingent  assets  and
liabilities at the date of the financial statements, and the reported amounts of expenses during the reported period. We base
our estimates on historical experience, known trends and events and various other factors that we believe 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. We evaluate our estimates and assumptions on an ongoing basis.
Our actual results may differ from these estimates under different assumptions and conditions.

While  our  significant  accounting  policies  are  described  in  more  detail  in  the  notes  to  our  consolidated  financial
statements appearing elsewhere in this Annual Report on Form 10-K, we believe that the following accounting policies are
those most critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

We account for revenue in accordance with Accounting Standards Codification, or ASC, Topic 606, Revenue from
Contracts with Customers.  Under ASC Topic 606, revenue is recognized when a customer obtains control of promised goods
or  services  in  an  amount  that  reflects  the  consideration  to  which  we  expect  to  be  entitled  in  exchange  for  those  goods  or
services. 

To  determine  revenue  recognition  in  accordance  with  ASC  Topic  606,  we  perform  the  following  five  steps:  (i)
identify  the  contract(s)  with  a  customer,  (ii)  identify  the  performance  obligations  in  the  contract,  (iii)  determine  the
transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue
when  (or  as)  performance  obligations  are  satisfied.    We  recognize  revenue  when  collection  of  the  consideration  we  are
entitled  to  under  a  contract  with  a  customer  is  probable.   At  contract  inception,  we  assess  the  goods  or  services  promised
within a contract with a customer to identify the performance obligations, and to determine if they are distinct.  We recognize
revenue that is allocated to each distinct performance obligation when (or as) that performance obligation is satisfied. 

Product Sales, net

We  recognize  revenue  from  product  sales  at  the  point  the  customer  obtains  control,  which  generally  occurs  upon
delivery,  and  also  include  estimates  of  variable  consideration  in  the  same  period  revenue  is  recognized.    Components  of
variable  consideration  include  trade  discounts  and  allowances,  product  returns,  government  rebates,  discounts  and  rebates,
other incentives such as patient co-pay assistance, and other fee for service amounts.  Variable consideration is recorded on
the consolidated balance sheet as either a reduction of accounts receivable, if payable to a customer, or as a current liability, if
payable to a third-party other than a customer.  We consider all relevant information when estimating variable consideration
such as current contractual and statutory requirements, specific known market events and trends, industry data and forecasted
customer buying and payment patterns.  The amount of net revenue we can recognize is constrained by estimates of variable
consideration  which  are  included  in  the  transaction  price.    Payment  terms  with  customers  do  not  exceed  one  year  and,
therefore, we do not account for a financing component in our arrangements.  We expense incremental costs of obtaining a
contract with a customer, including sales commissions, when incurred as the period of benefit is less than one year. Shipping
and  handling  costs  for  product  shipments  to  customers  are  recorded  as  sales  and  marketing  expenses  in  the  consolidated
statement of operations. 

Trade Discounts and Allowances  -  We  may  provide  customers  with  trade  discounts,  rebates,  allowances  or  other

incentives.  We record an estimate for these items as a reduction of revenue in the same period the revenue is recognized. 

Government  and  Payor  Rebates  –  We  may  contract  with  certain  third-party  payors,  primarily  health  insurance
companies, pharmacy benefit managers and government programs, for the payment of rebates with respect to utilization of
our products.  We also have agreements with GPOs that provide for administrative fees and discounted pricing in the form of
volume-based rebates.  We are also subject to discount obligations under state Medicaid programs and Medicare.  We record
an estimate for these rebates as a reduction of revenue in the same period the revenue is recognized. 

78

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Other Incentives - Other incentives includes our co-pay assistance program which is intended to provide financial
assistance to qualified commercially-insured patients with prescription drug co-payments required by payors.  We estimate
and record an accrual for these incentives as a reduction of revenue in the period the revenue is recognized.   Our estimated
amounts  for  co-pay  assistance  are  based  upon  the  number  of  claims  and  the  cost  per  claim  that  we  expect  to  receive
associated with product that has been sold to customers but remains in the distribution channel at the end of each reporting
period. 

Product Returns - Consistent with industry practice, we have a product returns policy which may provide customers
a right of return for product purchased within a specified period prior to and subsequent to the product’s expiration date.  The
right of return lapses upon shipment of the goods to a patient.  We record an estimate for the amount of product which may
be returned as a reduction of revenue in the period the related revenue is recognized.  Our estimates for product returns are
based  upon  available  industry  data  and  our  own  sales  information,  including  visibility  into  the  inventory  remaining  in  the
distribution  channel.    There  is  no  returns  liability  associated  with  sales  of  ESKATA  as  we  have  a  no  returns  policy  for
ESKATA. 

Contract Research

Revenue related to laboratory services is generally recognized as the laboratory services are performed, based upon
the  rates  specified  in  the  contracts.    Under  ASC  Topic  606,  we  elected  to  apply  the  “right  to  invoice”  practical  expedient
when recognizing contract research revenue.  We recognize contract research revenue in the amount to which we have the
right to invoice. 

We recognize revenue related to grants as amounts become reimbursable under each grant, which is generally when

research is performed, and the related costs are incurred. 

Other Revenue

Licenses of Intellectual Property – We recognize revenue received from non-refundable, upfront fees related to the
licensing  of  intellectual  property  when  the  intellectual  property  is  determined  to  be  distinct  from  the  other  performance
obligations identified in the arrangement, the license has been transferred to the customer, and the customer is able to use and
benefit from the license. 

Milestone Payments - At the inception of each arrangement that includes milestone payments, we evaluate whether
the milestones are considered probable of being reached and estimate the amount to be included in the transaction price using
the most likely amount method.  If it is probable that a significant revenue reversal would not occur, the associated milestone
value is included in the amount allocated to the license of intellectual property.  Milestone payments that are not within our
control or the control of the customer, such as regulatory approvals, are not considered probable of being achieved until those
approvals are received.

Inventory

Inventory  includes  the  third-party  cost  of  manufacturing  and  assembly  of  the  finished  product  forms  of  ESKATA
and  RHOFADE,  quality  control  and  other  overhead  costs.    Inventory  is  stated  at  the  lower  of  cost  or  net  realizable
value.  Inventory is adjusted for short-dated, unmarketable inventory equal to the difference between the cost of inventory
and the estimated value based upon assumptions about future demand and market conditions.  Our inventory is comprised
primarily of finished goods.

Intangible Assets

Our  intangible  assets  include  both  finite-lived  and  indefinite-lived  assets.    Finite-lived  intangible  assets  are
amortized over their estimated useful life based on the pattern over which the intangible assets are consumed or otherwise
used  up.  If  that  pattern  cannot  be  reliably  determined,  the  straight-line  method  of  amortization  is  used.    Our  finite-lived
intangible assets consist of a research technology platform acquired through the acquisition of Confluence and the intellectual
property  rights  related  to  RHOFADE.    Our  indefinite-lived  intangible  assets  consist  of  an  in-process  research  and
development,  or  IPR&D,  drug  candidate  acquired  through  the  acquisition  of  Confluence.    IPR&D  assets  are  considered
indefinite-lived until the completion or abandonment of the associated research and development efforts.  The cost of IPR&D
assets  is  either  amortized  over  their  estimated  useful  life  beginning  when  the  underlying  drug  candidate  is  approved  and
launched commercially, or expensed immediately if development of the drug candidate is abandoned. 

Finite-lived intangible assets are tested for impairment when events or changes in circumstances indicate that the
carrying  value  of  the  asset  may  not  be  recoverable.    Indefinite-lived  intangible  assets  are  tested  for  impairment  at  least
annually,  which  we  perform  during  the  fourth  quarter,  or  when  indicators  of  an  impairment  are  present.   We  recognize  an
impairment  loss  when  and  to  the  extent  that  the  estimated  fair  value  of  an  indefinite-lived  intangible  asset  is  less  than  its
carrying value. 

Goodwill

Goodwill is not amortized, but rather is subject to testing for impairment at least annually, which we perform during
the  fourth  quarter,  or  when  indicators  of  an  impairment  are  present.    We  consider  each  of  our  operating  segments,
dermatology  therapeutics  and  contract  research,  to  be  a  reporting  unit  since  this  is  the  lowest  level  for  which  discrete
financial information is available.  We have attributed the full amount of the goodwill in connection with the acquisition of
Confluence, or $18.5 million, to our dermatology therapeutics segment.  We perform an impairment test annually which is a
qualitative  assessment  based  upon  current  facts  and  circumstances  related  to  operations  of  the  dermatology  therapeutics
segment.  If our qualitative assessment indicates an impairment may be present, we would perform the required quantitative
analysis and an impairment charge would be recognized to the extent that the estimated fair value of the reporting unit is less
than  its  carrying  amount.    However,  any  loss  recognized  would  not  exceed  the  total  amount  of  goodwill  allocated  to  that
reporting unit. 

Contingent Consideration

We initially recorded the contingent consideration related to future potential payments based upon the achievement
of  specified  development,  regulatory  and  commercial  milestones,  resulting  from  the  acquisition  of  Confluence,  at  its
estimated  fair  value  on  the  date  of  acquisition.    Changes  in  fair  value  reflect  new  information  about  the  likelihood  of  the
payment  of  the  contingent  consideration  and  the  passage  of  time.    For  example,  if  the  timing  of  the  development  of  an
acquired  drug  candidate,  or  the  size  of  potential  commercial  opportunities  related  to  an  acquired  drug,  differ  from  our
assumptions, then the fair value of contingent consideration would be adjusted accordingly.  Future changes in the fair value
of the contingent consideration, if any, will be recorded as income or expense in our consolidated statement of operations. 

Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our research
and  development  expenses.  This  process  involves  reviewing  open  contracts  and  purchase  orders,  communicating  with  our
applicable  personnel  to  identify  services  that  have  been  performed  on  our  behalf  and  estimating  the  level  of  service
performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual
costs. The majority of our preclinical development activities and clinical trials are performed pursuant to quotes and contracts
with  multiple  vendors,  including  research  institutions  and  CROs,  that  conduct  and  manage  such  activities  on  our
behalf.    Many  of  the  contracts  with  our  vendors  require  advance  payments;  while  others  invoice  us  in  arrears  for  services
performed, or on a pre-determined schedule, or upon the successful enrollment of patients, or when contractual milestones
are met. We record expenses for preclinical development activities and clinical trials based upon estimates of the total cost of
the services to be provided by the vendor and the time period over which the vendor is to perform those services.  Estimates
of research and development expenses included in our consolidated financial statements are based on facts and circumstances
known to us at that time. The financial terms of our agreements are subject to negotiation, vary from contract to contract, and
may result in uneven payment flows. There may be times when payments made to a vendor exceed the

80

 
 
 
 
 
 
 
 
 
Table of Contents

level  of  services  provided,  resulting  in  a  prepayment  for  work  to  be  performed.    We  may  confirm  the  accuracy  of  our
estimates  with  the  service  providers,  or  make  adjustments  to  our  estimates  based  upon  new  or  updated  facts  and
circumstances, as necessary.  For example, if the timing and/or cost of services to be performed is materially different from
our previous estimates, we would make a prospective adjustment for the change in our estimates in the period in which we
become aware of the new cost and/or timing. Although we do not expect our estimates to be materially different from actual
amounts incurred, our understanding of the status and timing of services performed relative to the actual status and timing of
services performed may vary and may result in reporting amounts that are too high or too low in any particular period.  To
date, we have not made any material adjustments to our estimates of research and development expenses.

Stock-Based Compensation

We measure the compensation expense of stock-based awards granted to employees and directors using the grant
date  fair  value  of  the  award.    We  have  issued  stock  options  and  restricted  stock  unit,  or  RSU,  awards  with  service-based
vesting conditions, as well as with performance-based vesting conditions.  We have not issued awards that include market-
based conditions.  For service-based awards we recognize stock-based compensation expense on a straight-line basis over the
requisite service period.  For performance-based awards we recognize stock-based compensation expense on a straight-line
basis  over  the  requisite  service  period  beginning  in  the  period  that  it  becomes  probable  the  performance  conditions  will
occur.  At each balance sheet date, we evaluate whether any performance conditions related to a performance-based award
have changed.  The effect of any change in performance conditions would be recognized as a cumulative catch-up adjustment
in the period such change occurs, and any remaining unrecognized compensation expense would be recognized on a straight-
line basis over the remaining requisite service period.  The impact of forfeitures is recognized in the period in which they
occur. 

We initially measure the compensation expense of stock-based awards granted to consultants using the grant date
fair  value  of  the  award.    We  recognize  compensation  expense  over  the  period  during  which  services  are  rendered  by  the
consultant.  At the end of each financial reporting period prior to the completion of services being rendered, we re-measure
the compensation expense related to these awards using the then current fair value of our common stock for RSUs, or based
upon updated assumptions in the Black-Scholes option-pricing model for stock option awards. 

We estimate the fair value of each stock option grant using the Black-Scholes option-pricing model.  We estimate
expected  volatility  based  on  historical  volatility  of  a  set  of  peer  companies,  which  are  publicly  traded,  and  we  expect  to
continue to do so until we have adequate historical data regarding the volatility of our own publicly-traded stock price.  The
expected  term  of  our  stock  options  has  been  determined  using  the  “simplified”  method  for  awards  that  qualify  as  “plain
vanilla”  options.  The  expected  term  of  stock  options  we  granted  to  non-employees  is  equal  to  the  contractual  term  of  the
option award.  The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of
grant of the award for time periods approximately equal to the expected term of the award.  We use an expected dividend
yield  of  zero  because  we  have  not  paid  cash  dividends  to  date,  and  have  no  intention  of  paying  cash  dividends  in  the
future.  Prior to our IPO, we valued our common stock using a hybrid method which used market approaches to estimate our
enterprise value.  The hybrid method used was a probability-weighted expected return method which was a scenario-based
methodology  that  estimated  the  fair  value  of  our  common  stock  based  upon  an  analysis  of  future  values  for  the  company
assuming various outcomes.  The hybrid method used calculated equity values using an option pricing model in one or more
of scenarios, and also considered the rights of each class of stock.

The fair value of each RSU is measured using the closing price of our common stock on the date of grant.

Income Taxes

Since our inception in 2012, we have not recorded U.S. federal or state income tax benefits for the net operating
losses  we  have  incurred  in  each  year  or  for  our  earned  research  and  development  tax  credits,  due  to  our  uncertainty  of
realizing a benefit from those items.

Revenue  was  $10.1  million  for  the  year  ended  December  31,  2018,  compared  to  $1.7  million  for  the  year  ended
December 31, 2017.  Product sales, net included $2.8 million and $1.1 million of net revenue from sales of ESKATA and
RHOFADE, respectively, during the year ended December 31, 2018.  We acquired RHOFADE in November 2018.  Contract
research  revenue  of  $4.7  million  and  $1.7  million  for  the  years  ended  December  31,  2018  and  2017,  respectively,  was
comprised  primarily  of  fees  earned  from  the  provision  of  laboratory  services  to  clients  through  Confluence,  which  we
acquired in August 2017.  Other revenue was related to the Cipher License Agreement and consisted of an upfront payment
of $1.0 million and $0.5 million earned upon the achievement of a specified regulatory milestone. 

Cost of Revenue

Cost of revenue was $6.9 million for the year ended December 31, 2018 and was comprised of $1.5 million and $1.0
million of costs related to ESKATA and RHOFADE product sales, net, respectively.  Cost of revenue included $0.6 million of
non-cash amortization related to the intangible asset for the RHOFADE intellectual property rights, and a non-cash charge of
$1.1  million  related  to  the  write-down  of  ESKATA  finished  inventory.    We  also  incurred  $4.3  million  of  costs  related  to
providing  laboratory  services  to  our  clients  through  Confluence.    Cost  of  revenue  was  $1.2  million  for  the  year  ended
December  31,  2017  and  was  comprised  entirely  of  costs  incurred  to  provide  laboratory  services  to  our  clients  through
Confluence, which we acquired in August 2017.

The  decrease  in  expenses  associated  with  the  development  of  ESKATA  resulted  primarily  from  the  filing  of  our
NDA  in  February  2017  following  the  completion  of  clinical  trials.    Expenses  related  to  A-101  45%  Topical  Solution
increased  primarily  due  to  the  initiation  of  our  Phase  3  clinical  trials  for  the  treatment  of  common  warts  during  the  third
quarter of 2018.  Development expenses for our JAK inhibitors increased due to continued growth in both preclinical and
clinical trial expenses as we continue to conduct multiple Phase 2 clinical trials of ATI-501 and ATI-502.  The increase in
personnel expenses was primarily the result of increased headcount.  The increase in stock-based compensation expense was
primarily the result of new awards granted during 2018.  The change in contingent consideration was the result of updates to
our  assumptions  related  to  our  soft-JAK  inhibitors  that  reflected  the  achievement  of  a  specified  development  milestone  in
November 2018 under the Confluence Agreement.  Other research and development expenses primarily included expenses
for medical affairs activities related to ESKATA, and expenses related to drug discovery performed by Confluence, which we
acquired in August 2017; we did not incur similar drug discovery expenses prior to that acquisition.  The increase in other
research and development expenses was also driven by preclinical development of ATI-450, our MK-2 inhibitor, and research
expenses related to our ITK inhibitor.

Direct marketing and professional fees, as well as other sales and marketing expenses, increased as a result of the
commercial  launch  of  ESKATA,  which  occurred  in  May  2018.    Personnel  and  stock-based  compensation  expenses  have
increased  due  to  increased  headcount,  including  the  hiring  of  our  field  sales  force  during  the  year  ended  December  31,
2018.    Other  sales  and  marketing  expenses  included  sales  operations,  travel  costs,  depreciation  and  other  miscellaneous
expenses.    Other  sales  and  marketing  expenses  included  costs  related  to  our  national  launch  meeting,  employee  training,
samples fulfillment and expenses related to leasing a fleet of vehicles.  The increase in other sales and marketing expenses
was primarily related to onboarding our field sales force during the year ended December 31, 2018.

Personnel and stock-based compensation expenses have increased due to increased headcount as we expanded our
operations.  Professional and legal fees included accounting, legal and investor relations costs associated with being a public
company,  as  well  as  legal  fees  related  to  patents.    The  increase  in  professional  and  legal  fees  was  related  to  legal  and
consulting expenses incurred as a result of the commercial launch of ESKATA in May 2018, as well as fees associated with
business  development  activities.   The  milestone  payment  of  $1.5  million  in  the  year  ended  December  31,  2018  was  made
upon  the  achievement  of  specified  commercial  milestones  under  our  Finder’s  Services  Agreement  with  KPT  Consulting,
LLC.    The  milestone  payment  of  $1.0  million  in  the  year  ended  December  31,  2017  was  made  upon  the  achievement  of
specified  regulatory  milestones  pursuant  to  our  Finder’s  Services  Agreement  with  KPT  Consulting,  LLC.    Facility  and
support services included general office expenses and information technology costs which have risen due to our increased
headcount  as  well  as  the  relocation  of  our  headquarters  during  the  year  ended  December  31,  2018.    Other  general  and
administrative expenses included insurance, travel costs, depreciation and other miscellaneous expenses. 

Other Income, net

The  $0.6  million  increase  in  other  income,  net  was  primarily  due  to  higher  invested  balances  of  marketable
securities as a result of funds received from our financing transactions in 2017 and 2018, as well as higher yields on those
invested balances. 

Provision for (Benefit from) Income Taxes

Provision  for  income  taxes  was  a  net  benefit  of  $1.8  million  for  the  year  ended  December  31,  2017  and  was
comprised primarily of the revaluation of our deferred tax assets, net resulting from the Tax Cuts and Jobs Act of 2017 which
was enacted on December 22, 2017.

Revenue was $1.7 million for the year ended December 31, 2017, and was comprised primarily of fees earned from
the provision of laboratory services to clients through Confluence, which we acquired in August 2017.  We did not generate
any revenue in the year ended December 31, 2016. 

Cost of Revenue

Cost  of  revenue  was  $1.2  million  for  the  year  ended  December  31,  2017,  and  was  comprised  entirely  of  costs
incurred to provide laboratory services to our clients through Confluence, which we acquired in August 2017.  We did not

The increase of $6.3 million in research and development was primarily driven by an increase of $3.6 million of
expenses related to our Phase 2 clinical trials of A-101 45% Topical Solution, an increase of $4.5 million in preclinical and
clinical  trial  development  expenses  related  to  our  JAK  inhibitor  technology,  increases  of  $2.4  million  in  payroll-related
expenses and $3.2 million in stock-based compensation expense, both of which were due to higher headcount, and a $2.9
million increase in expenses related to medical affairs activities.  We also incurred $1.0 million of expenses related to drug
discovery research performed by Confluence in the year ended December 31, 2017.  The increases noted above were partially
offset by a $8.2 million decrease in costs associated with the development of ESKATA as a result of the completion of our
Phase 3 clinical trials in November 2016, and $3.4 million in expenses associated with the acquisition of Vixen in the year
ended December 31, 2016, for which there was no similar transaction in 2017.

expenses  related  to  pre-commercial  launch  activities  for  ESKATA.    Personnel  and  stock-based  compensation  expenses
increased due to increased headcount, including the hiring of regional sales managers and sales operations employees during
the year ended December 31, 2017.  Other sales and marketing expenses included sales operations, travel costs, depreciation
and other miscellaneous expenses and increased primarily as a result of pre-commercial launch activities for ESKATA.

patents.  Facilities and support services included a one-time charge to rent expense of $0.5 million in connection with the

Other Income, net

The  $1.6  million  increase  in  other  income,  net  was  primarily  due  to  higher  invested  balances  of  marketable

securities as a result of funds received from our financing transactions in 2016 and 2017. 

Provision for (Benefit from) Income Taxes

Provision  for  income  taxes  was  a  net  benefit  of  $1.8  million  for  the  year  ended  December  31,  2017  and  was
comprised primarily of the revaluation of our deferred tax assets, net resulting from the Tax Cuts and Jobs Act of 2017 which
was enacted on December 22, 2017.  

Liquidity and Capital Resources

Since  our  inception,  we  have  incurred  net  losses  and  negative  cash  flows  from  our  operations.    Prior  to  our
acquisition of Confluence in August 2017, we did not generate any revenue.  We have financed our operations over the last
several  years  primarily  through  sales  of  our  equity  securities  in  public  offerings  and  a  private  placement  transaction.   As
described below, in October 2018 we also entered into a loan facility with an institutional lender. 

As  of  December  31,  2018,  we  had  cash,  cash  equivalents  and  marketable  securities  of  $168.0  million.    Cash  in
excess  of  immediate  requirements  is  invested  in  accordance  with  our  investment  policy,  primarily  with  a  view  towards
liquidity and capital preservation. 

We  currently  have  no  ongoing  material  financing  commitments,  such  as  lines  of  credit  or  guarantees,  that  are
expected to affect our liquidity over the next five years, other than our recent debt financing obligation, sublease obligations,
capital lease obligations and contingent obligations under acquisition and intellectual property licensing agreements, which
are summarized below under “Contractual Obligations and Commitments.”  

Private Placement

In June 2016, we closed a private placement in which we sold an aggregate of 1,081,082 shares of common stock at
a  price  of  $18.50  per  share,  for  gross  proceeds  of  $20.0  million.    We  incurred  placement  agent  fees  of  $1.3  million,  and
expenses of $0.2 million in connection with the private placement.  As a result, the net offering proceeds received by us, after
deducting placement agent fees and transaction expenses, were $18.5 million. 

November 2016 Public Offering

In November 2016, we closed a public offering in which we sold 4,600,000 shares of common stock at a price to the
public of $22.75 per share, for aggregate gross proceeds of $104.7 million. We paid underwriting discounts and commissions
of $6.3 million, and we also incurred expenses of $0.2 million in connection with the offering.  As a result, the net offering
proceeds received by us, after deducting underwriting discounts, commissions and offering expenses, were $98.2 million. 

At-The-Market Facility

In  November  2016,  we  entered  into  a  sales  agreement  with  Cowen  and  Company,  LLC,  or  Cowen,  pursuant  to
which Cowen acted as our agent in connection with sales of our common stock from time to time under an “at-the-market”
equity facility.  In April 2017, we sold 635,000 shares of our common stock at a weighted average price per share of $31.50,
for  aggregate  gross  proceeds  of  approximately  $20.0  million.    We  paid  underwriting  discounts  and  commissions  of  $0.6
million, and we also incurred expenses of $0.1 million in connection with this sale.  In October 2018, we terminated the at-
the-market sales agreement with Cowen without having sold any additional shares of common stock.

August 2017 Public Offering

In August 2017, we closed our follow-on public offering in which we sold 3,747,602 shares of common stock at a
price to the public of $23.02 per share, for aggregate gross proceeds of $86.3 million. We paid underwriting discounts and
commissions of $5.2 million, and we also incurred expenses of $0.2 million in connection with the offering.  As a result, the
net offering proceeds received by us, after deducting underwriting discounts, commissions and offering expenses, were $80.9
million. 

October 2018 Public Offering

In October 2018, we closed a public offering in which we sold 9,941,750 shares of common stock at a price to the
public of $10.75 per share, for aggregate gross proceeds of $106.9 million.  We paid underwriting discounts and commissions
of $6.4 million to the underwriters, and we incurred expenses of $0.3 million in connection with the offering.  As a result, the
net  offering  proceeds  received  by  us,  after  deducting  underwriting  discounts,  commissions  and  offering  expenses,  were
$100.2 million. 

Loan and Security Agreement with Oxford 

In October 2018, we entered into a loan and security agreement, or the Loan and Security Agreement, with Oxford
Finance LLC, or Oxford. The Loan and Security Agreement provides for up to $65.0 million in term loans.  Of the $65.0
million, we borrowed $30.0 million in October 2018. The remaining $35.0 million is available for draw ending on the earlier
of March 31, 2019 or an event of default. Should we not draw all or a portion of the $35.0 million during the applicable draw
timeframe, or if we prepay the entirety of the amount drawn during the applicable draw timeframe, we will be required to pay
Oxford a non-utilization fee equal to 1.0% of the undrawn portion. 

The Loan and Security Agreement provides for interest only payments through the payment date immediately prior
to  November  1,  2021,  followed  by  24  consecutive  equal  monthly  payments  of  principal  and  interest  in  arrears  starting  on
November 1, 2021 and continuing through the maturity date of October 1, 2023. All unpaid principal and accrued and unpaid
interest will be due and payable on the maturity date.  The Loan and Security Agreement provides for an annual interest rate
equal to the greater of (i) 8.35% and (ii) the 30-day U.S. LIBOR rate reported in The Wall Street Journal on the last business
day of the month that immediately precedes the month in which the interest will accrue plus 6.25%. The Loan and Security
Agreement also provides for a final payment equal to 5.75% of the original principal amount of the term loans drawn, which
final payment is due on October 1, 2023 or upon the prepayment of the facility or the acceleration of amounts due under the
facility as a result of an event of default.

We have the option to prepay the outstanding balance of the term loans in full, subject to a prepayment fee of (i) 3%
of the original principal amount of the aggregate term loans drawn for any prepayment prior to the first anniversary of the
applicable  funding  date,  (ii)  2%  of  the  original  principal  amount  of  the  aggregate  term  loans  drawn  for  any  prepayment
between the first and second anniversaries of the applicable funding date or (iii) 1% of the original principal amount of the
aggregate  term  loans  drawn  for  any  prepayment  after  the  second  anniversary  of  the  applicable  funding  date  but  before
October 1, 2023. We also have the option to prepay the term loans in part, once in a three-month period, of an amount of $2.0
million or greater, subject to the same prepayment fees and other specified limitations.

Our obligations under the Loan and Security Agreement are secured by substantially all of our assets, except that the
collateral  does  not  include  our  intellectual  property.  However,  we  have  agreed  not  to  encumber  any  of  our  intellectual
property.  The  Loan  and  Security  Agreement  contains  customary  representations,  warranties  and  covenants,  including
covenants that limit our ability, subject to specified exceptions, to convey, sell, lease, transfer, assign or otherwise dispose of
assets; engage in any business other than the businesses currently engaged in; liquidate or dissolve; undergo specified change
of control events; create, incur, assume or be liable for indebtedness; create, incur, allow or suffer any liens on property; pay
dividends and make other restricted payments; make investments; or enter into any material transactions with affiliates. The
Loan and Security Agreement also contains specified financial covenants related to minimum consolidated future revenues.

The  Loan  and  Security  Agreement  also  contains  customary  indemnification  obligations  and  customary  events  of
default,  including,  among  other  things,  our  failure  to  fulfill  our  obligations  under  the  Loan  and  Security  Agreement,  the
occurrence  of  a  material  adverse  change,  specified  defaults  or  our  failure  to  keep  our  common  stock  listed  on  the  Nasdaq
Stock Market. In the event of default, Oxford would be entitled to exercise its remedies thereunder, including the right to

During the year ended December 31, 2018, operating activities used $100.8 million of cash primarily resulting from
our net loss of $132.7 million, partially offset by changes in our operating assets and liabilities of $9.4 million, and non-cash
adjustments  of  $23.2  million.    Net  cash  provided  by  changes  in  our  operating  assets  and  liabilities  during  the  year  ended
December  31,  2018  consisted  of  a  $13.8  million  increase  in  accounts  payable  and  accrued  expenses,  which  was  partially
offset  by  a  $4.4  million  increase  in  accounts  receivable.    The  increase  in  accounts  payable  and  accrued  expenses  was
primarily driven by expenses incurred, but not yet paid, as of December 31, 2018, as well as the timing of vendor invoicing
and  payments.    Expenses  incurred,  but  not  yet  paid,  as  of  December  31,  2018  primarily  included  sales  and  marketing
expenses  related  to  the  commercial  launch  of  ESKATA  in  the  United  States  in  May  2018,  amounts  payable  for  copay
assistance  and  commercial  rebates  related  to  sales  of  RHOFADE  which  we  began  selling  in  December  2018,  as  well  as
expenses related to our Phase 3 clinical trials for A-101 45% Topical Solution, and our Phase 2 clinical trials for ATI-501 and
ATI-502.  The increase in accounts receivable was the result of the commercial launch of ESKATA in May 2018, and sales of
RHOFADE which we acquired in November 2018.  Non-cash expenses of $23.2 million were primarily composed of stock-
based compensation expense.

During the year ended December 31, 2017, operating activities used $54.7 million of cash primarily resulting from
our net loss of $68.5 million, partially offset by changes in our operating assets and liabilities of $0.9 million and non-cash
adjustments  of  $13.0  million.    Net  cash  used  by  changes  in  our  operating  assets  and  liabilities  during  the  year  ended
December 31, 2017 consisted of a $4.3 million increase in prepaid expenses and other current assets offset by a $5.2 million
increase in accounts payable and accrued expenses.  The increase in prepaid expenses and other current assets was primarily
due to a $2.0 million PDUFA fee paid to the FDA in conjunction with the filing of the NDA for ESKATA, as well as deposits
made for clinical supplies and development activities that were incurred during 2018.  The increase in accounts payable and
accrued expenses was primarily due to an increase of $1.2 million in accrued bonuses payable due to increased headcount,
$0.6 million payable to NST Consulting LLC in connection with the early termination of our sublease with them, as well as
expenses incurred, but not yet paid, in connection with our Phase 2 clinical trials for A-101 45% Topical Solution, ATI-501
and ATI-502.  Non-cash expenses of $13.0 million included stock-based compensation expense of $14.4 million, and $0.4
million of depreciation and amortization, partially offset by an adjustment to our deferred tax liability, net of $1.8 million
which was the result of the Tax Cuts and Jobs Act of 2017 enacted on December 22, 2017.

During the year ended December 31, 2016, our operating activities used $34.6 million of cash primarily resulting
from our net loss of $48.1 million, partially offset by cash provided by changes in our operating assets and liabilities of $4.5
million and by non-cash expenses of $9.0 million. Net cash provided by changes in our operating assets and liabilities during
the year ended December 31, 2016 consisted primarily of a $4.3 million increase in accounts payable and accrued expenses.
The  increase  in  accounts  payable  and  accrued  expenses  was  primarily  due  to  expenses  incurred,  but  not  yet  paid,  in
connection  with  preclinical  development  expenses  related  to  our  JAK  inhibitor  technology  and  the  timing  of  vendor
invoicing and payments.  In addition, we had $1.7 million of employee-related accruals as of December 31, 2016, compared
to $0 as of December 31, 2015.  The increase in employee-related accruals resulted from bonuses earned in 2016 which were
paid after December 31, 2016, while all bonuses earned in 2015 were paid before December 31, 2015.  Non-cash expenses of
$9.0 million primarily included $6.1 million related to stock-based compensation expense, and $2.8 million resulting from
the Vixen acquisition. 

Investing Activities

During the year ended December 31, 2018, investing activities provided $9.4 million of cash, consisting of proceeds
from sales and maturities of marketable securities of $239.4 million, partially offset by purchases of marketable securities of
$161.6 million, $67.1 million for the purchase of RHOFADE, and purchases of equipment of $1.4 million. 

During the year ended December 31, 2017, investing activities used $55.7 million of cash, consisting of purchases
of  marketable  securities  of  $197.3  million,  $9.6  million  for  the  acquisition  of  Confluence  and  purchases  of  property  and
equipment of $1.2 million, partially offset by proceeds from sales and maturities of marketable securities of $152.5 million.

During the year ended December 31, 2016, investing activities used $61.9 million of cash, consisting of purchases
of marketable securities of $148.8 million and purchases of equipment of $0.2 million, partially offset by proceeds from sales
and maturities of marketable securities of $87.1 million.

Financing Activities

During  the  year  ended  December  31,  2018,  financing  activities  provided  $128.3  million  of  cash  and  included  net
proceeds  of  $100.2  million  received  from  our  public  offering  of  common  stock  in  October  2018,  $29.9  million  of  net
borrowings pursuant to the Loan and Security Agreement with Oxford, and $0.6 million of cash received from the exercise of
employee  stock  options,  partially  offset  by  $1.8  million  paid  to  the  former  Confluence  equity  holders  as  a  result  of  the
achievement of a development milestone and $0.6 million of capital lease payments.

During the year ended December 31, 2017, financing activities provided $100.4 million of cash and included $19.3
million of net proceeds received from the sale of common stock under our sales agreement with Cowen in April 2017, $80.9
million of net proceeds received from our public offering of common stock in August 2017, and $0.2 million of cash received
from  the  exercise  of  employee  stock  options,  partially  offset  by  $0.1  million  of  capital  lease  payments  for  laboratory
equipment. 

During the year ended December 31, 2016, financing activities provided $116.8 million of cash and included $18.5
million of net proceeds received from the private placement of our common stock in June 2016, net proceeds of $98.2 million
received  from  our  public  offering  of  common  stock  in  November  2016,  as  well  as  $0.1  million  of  cash  received  from  the
exercise of employee stock options.    

Funding Requirements

We  plan  to  focus  in  the  near  term  on  the  commercialization  of  ESKATA  for  the  treatment  of  raised  SKs,  and
RHOFADE  for  the  treatment  of  persistent  facial  erythema  associated  with  rosacea  in  adults,  as  well  as  the  clinical
development  of  our  drug  candidates.    We  anticipate  we  will  incur  net  losses  for  the  next  several  years  as  we  continue  to
commercialize ESKATA and RHOFADE, continue the clinical development of A-101 45% Topical Solution for the treatment
of  common  warts  and  continue  research  and  development  of  ATI-501  and  ATI-502  for  the  treatment  of  AA  and  other
dermatological conditions, as well as the identification, research and development of other compounds.  We plan to continue
to invest in discovery efforts to explore additional drug candidates, build commercial capabilities and expand our

90

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

corporate infrastructure. We may not be able to complete the development and initiate commercialization of these programs
if, among other things, our clinical trials are not successful or if the FDA does not approve our drug candidates currently in
clinical trials when we expect, or at all. 

Our  primary  uses  of  capital  are,  and  we  expect  will  continue  to  be,  compensation  and  related  expenses,  clinical
costs,  external  research  and  development  services,  laboratory  and  related  supplies,  sales,  marketing  and  advertising  costs,
legal and other regulatory expenses, and administrative and overhead costs.  In addition, in 2019 we plan to invest in a new
research  facility  for  our  drug  discovery  operations.    Our  future  funding  requirements  will  be  heavily  determined  by  the
resources  needed  to  support  the  commercialization  of  ESKATA  and  RHOFADE,  as  well  as  the  development  of  our  drug
candidates. 

As a publicly traded company, we have incurred and will continue to incur significant legal, accounting and other
expenses that we were not required to incur as a private company.  In addition, the Sarbanes-Oxley Act of 2002, as well as
rules adopted by the SEC and the Nasdaq Stock Market LLC, requires public companies to implement specified corporate
governance practices that were not applicable to us prior to our IPO.  We expect ongoing compliance with these rules and
regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and
costly. 

We  believe  our  existing  cash,  cash  equivalents  and  marketable  securities  are  sufficient  to  fund  our  operating  and
capital expenditure requirements for a period greater than 12 months from the date of issuance of our consolidated financial
statements that appear in Item 8 of this Annual Report on Form 10-K based on our current operating assumptions including
the commercialization of ESKATA and RHOFADE, conducting Phase 3 clinical trials for A-101 45% Topical Solution for
the treatment of common warts, the continued development of ATI-501 and ATI-502 as potential treatments for AA and other
dermatological indications, and the development of ATI-450 as a potential treatment for psoriasis and other dermatological
conditions.  These assumptions may prove to be wrong, and we could utilize our available capital resources sooner than we
expect.  We expect that we will require additional capital to commercialize A-101 45% Topical Solution for the treatment of
common  warts,  if  approved,  to  complete  the  clinical  development  of  ATI-501  and  ATI-502,  to  develop  our  preclinical
compounds,  to  support  our  discovery  efforts,  and  to  pursue  in-licenses  or  acquisitions  of  other  drug  candidates.    We  also
expect  to  incur  significant  expenses  related  to  the  commercialization  of  ESKATA  and  RHOFADE,  including  product
manufacturing, sales, marketing, advertising and distribution costs.  Additional funds may not be available on a timely basis,
on  commercially  acceptable  terms,  or  at  all,  and  such  funds,  if  raised,  may  not  be  sufficient  to  enable  us  to  continue  to
implement  our  long-term  business  strategy.  If  we  are  unable  to  raise  sufficient  additional  capital,  we  may  need  to
substantially curtail our planned operations and the pursuit of our growth strategy. 

We  may  raise  additional  capital  through  the  sale  of  equity  or  convertible  debt  securities.  In  such  an  event,  your
ownership will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect
the rights of a holder of our common stock.

Because  of  the  numerous  risks  and  uncertainties  associated  with  research,  development  and  commercialization  of
pharmaceutical drugs, we are unable to estimate the exact amount of our working capital requirements. Our future funding
requirements will depend on many factors, including:

·
·
·
·

·

·

·
·
·

·

the extent to which we in-license or acquire additional drug candidates and technologies;
the number and development requirements of the drug candidates that we may pursue;
the costs, timing and outcome of regulatory review of our drug candidates;
the scope, progress, results and costs of preclinical development, laboratory testing and conducting pre-clinical and
clinical trials for our drug candidates;
the cost of commercializing ESKATA and RHOFADE and the costs and timing of future commercialization
activities, including drug manufacturing, marketing, sales and distribution, for any of our drug candidates for which
we receive marketing approval;
the revenue received from commercial sales of ESKATA and RHOFADE and any of our drug candidates for which
we receive marketing approval;
the progress of obtaining marketing approval for ESKATA in select countries in the European Union and Norway;
our ability to establish collaborations to commercialize ESKATA and RHOFADE outside the United States;
the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our
intellectual property rights and defending any intellectual property-related claims; and
the timing, receipt and amount of sales of, or milestone payments related to or royalties on, our current or future
products or drug candidates, if any, as a result of licenses to, or partnership or collaborations with, third parties.

Under various agreements, we may be required to make milestone payments and pay royalties and other amounts to
third parties. We have not included any contingent payment obligations, such as milestones or royalties, in the table above as
the amount, timing and likelihood of such payments are not known. 

Under  the  assignment  agreement  pursuant  to  which  we  acquired  intellectual  property,  we  have  agreed  to  pay
royalties on sales of ESKATA or other related products at rates ranging in low single-digit percentages of net sales, as defined
in the agreement.  Under the related finder’s services agreement, we have also agreed to make a remaining payment of $3.0
million upon the achievement of a specified commercial milestone. In addition, we have agreed to pay royalties on sales of
ESKATA or other related products at a low single-digit percentage of net sales, as defined in the agreement. 

Under the Rigel License Agreement, we have agreed to make aggregate payments of up to $80.0 million upon the
achievement of specified pre-commercialization milestones, such as clinical trials and regulatory approvals. Further, we have
agreed to pay up to an additional $10.0 million to Rigel upon the achievement of a second set of development milestones.
With  respect  to  any  products  we  commercialize  under  the  Rigel  License  Agreement,  we  will  pay  Rigel  quarterly  tiered
royalties on our annual net sales of each product developed using the licensed JAK inhibitors at a high single digit percentage
of annual net sales, subject to specified reductions. 

Under  the  Vixen  Agreement,  we  are  obligated  to  make  aggregate  payments  of  up  to  $18.0  million  upon  the
achievement  of  specified  pre-commercialization  milestones  for  three  products  covered  by  the  Vixen  patent  rights  in  the
United  States,  the  European  Union  and  Japan,  and  aggregate  payments  of  up  to  $22.5  million  upon  the  achievement  of
specified commercial milestones for products covered by the Vixen patent rights.  We are also obligated to make an annual
payment of $0.1 million through March 2022, which amounts are creditable against any specified future payments that may
be paid under the Vixen Agreement.  With respect to any products we commercialize under the Vixen Agreement,  we  are
obligated  to  pay  low  single-digit  percentage  of  annual  net  sales,  subject  to  specified  reductions,  limitations  and  other
adjustments, until the date that all of the patent rights for that product have expired, as determined on a country-by-country
and product-by-product basis or, in specified circumstances, ten years from the first commercial sale of such product.  If we
sublicense any of the patent rights and know-how acquired pursuant to the Vixen Agreement, we will be obligated to pay a
portion of any consideration we receive from such sublicenses in specified circumstances. 

Under  the  Columbia  License  Agreement,  we  are  obligated  to  pay  an  annual  license  fee  of  $10,000,  subject  to
specified adjustments for patent expenses incurred by Columbia and creditable against any royalties that may be paid under
the license agreement.  We are also obligated to pay up to an aggregate of $11.6 million upon the achievement of specified
commercial milestones, including specified levels of net sales of products covered by Columbia patent rights and/or know-
how, and royalties at a sub-single-digit percentage of annual net sales of products covered by Columbia patent rights and/or
know-how,  subject  to  specified  adjustments.    If  we  sublicense  any  of  Columbia’s  patent  rights  and  know-how  acquired
pursuant to the Columbia License Agreement, we will be obligated to pay Columbia a portion of any consideration Vixen
receives from such sublicenses in specified circumstances. 

Under the Confluence Agreement with the former Confluence equity holders,  we are obligated to make remaining
aggregate  payments  of  up  to  $75.0  million  upon  the  achievement  of  specified  regulatory  and  commercialization
milestones.  With respect to any covered products we commercialize, we are obligated to pay a low single-digit percentage of
annual net sales, subject to specified reductions, limitations and other adjustments, until the date that all of the patent rights
for  that  product  have  expired,  as  determined  on  a  country-by-country  and  product-by-product  basis  or,  in  specified
circumstances, ten years from the first commercial sale of such product.  If we sublicense any of the patent rights and know-
how acquired pursuant to the Confluence Agreement, we will be obligated to pay a portion of any consideration we receive
from such sublicenses in specified circumstances. 

Under the Asset Purchase Agreement with Allergan pursuant to which we acquired intellectual property, we have
agreed  to  pay  Allergan  royalties  on  net  sales  of  RHOFADE  ranging  from  a  mid-single  digit  percentage  to  a  mid-teen
percentage of net sales, subject to specified reductions, limitations and other adjustments, on a country-by-country basis until
the  date  that  the  patent  rights  related  to  a  particular  product,  such  as  RHOFADE,  have  expired  or,  if  later,  November  30,
2028.    In  addition,  we  have  agreed  to  assume  the  obligation  to  pay  specified  royalties  and  milestone  payments  under
agreements with Aspect Pharmaceuticals, LLC and Vicept Therapeutics, Inc.  We have also agreed to pay Allergan a one-
time  payment  of  $5.0  million  upon  the  achievement  of  a  specified  development  milestone  related  to  the  potential
development of an additional dermatology product.

We enter into contracts in the normal course of business with CROs for clinical trials, preclinical research studies
and  testing,  manufacturing  and  other  services  and  products  for  operating  purposes.  These  contracts  generally  provide  for
termination  upon  notice,  and  therefore  we  believe  that  our  non-cancelable  obligations  under  these  agreements  are  not
material. 

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as

defined in the rules and regulations of the SEC. 

Recently Issued and Adopted Accounting Pronouncements

In November 2018, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or
ASU,  2018-18,  Collaborative  Arrangements  (Topic  808):    Clarifying  the  Interaction  Between  Topic  808  and  Topic  606,
which,  among  other  things,  provides  guidance  on  how  to  assess  whether  certain  collaborative  arrangement  transactions
should be accounted for under Topic 606.  The amendments in this ASU are effective for fiscal years, and interim periods
within those fiscal years, beginning after December 15, 2019, with early adoption permitted.  We are evaluating the impact of
ASU 2018-18 on our consolidated financial statements. 

In  August  2018,  the  FASB  issued  ASU  2018-15,  Intangibles—Goodwill  and  Other—Internal-Use  Software
(Subtopic 350-40).  ASU 2018-15 requires a customer in a cloud computing arrangement that is a service contract to follow
the  internal-use  software  guidance  in  Accounting  Standards  Codification,  or  ASC,  350-40  to  determine  which
implementation costs to capitalize as assets or expense as incurred.  The standard will be effective for fiscal years beginning
after  December  15,  2019,  including  interim  periods  within  such  fiscal  years,  with  early  adoption  permitted.    We  are
evaluating the impact of ASU 2018-15 on our consolidated financial statements. 

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820).  The FASB developed the
amendments  to  ASC  820  as  part  of  its  broader  disclosure  framework  project,  which  aims  to  improve  the  effectiveness  of
disclosures  in  the  notes  to  financial  statements  by  focusing  on  requirements  that  clearly  communicate  the  most  important
information  to  users  of  the  financial  statements.    This  update  eliminates  certain  disclosure  requirements  for  fair  value
measurements for all entities, requires public entities to disclose certain new information and modifies some of the existing
disclosure requirements.  The standard will be effective for fiscal years beginning after December 15, 2019, including interim
periods  within  such  fiscal  years,  with  early  adoption  permitted.    We  are  evaluating  the  impact  of  ASU  2018-13  on  our
consolidated financial statements. 

In June 2018, the FASB, issued ASU 2018-07, Compensation—Stock Compensation (Topic 718).  The amendments
in this ASU expand the scope of Topic 718 to include stock-based compensation arrangements with non-employees except
for  specific  guidance  on  option  pricing  model  inputs  and  cost  attribution.   ASU  2018-07  is  effective  for  annual  reporting
periods beginning after December 31, 2018, including interim periods within that year, and early adoption is permitted.  We
adopted this standard as of January 1, 2019, the impact of which on our consolidated financial statements was not significant.

In January 2017, the FASB issued ASU, 2017-01, Business Combinations—Clarifying the Definition of a Business
(Topic 805).    The amendments in this ASU provide a screen to determine when a set of acquired assets and/or activities is
not a business.  The screen requires that when substantially all of the fair value of the gross assets acquired, or disposed of, is
concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business.  The amendments
in  this  ASU  will  reduce  the  number  of  transactions  that  meet  the  definition  of  a  business.   ASU  2017-01  is  effective  for
annual reporting periods beginning after December 15, 2017, including interim periods within those years, and early adoption
was permitted.  We adopted this standard as of January 1, 2018, the impact of which on our consolidated financial statements
was not significant.   

In  June  2016,  the  FASB  issued  ASU  2016-13,  Financial  Instruments—Credit  Losses  (Topic  326).    This  ASU
introduces  a  new  model  for  recognizing  credit  losses  on  financial  instruments  based  upon  estimated  expected  credit
losses.  ASU 2016-13 will apply to loans, accounts receivable, financial assets measured at amortized cost and at fair value
through other comprehensive income, loan commitments and certain off-balance sheet credit exposures.   ASU 2016-13 is
effective

94

 
 
 
 
 
 
 
 
 
  
 
 
 
Table of Contents

for  annual  reporting  periods  beginning  after  December  15,  2019,  including  interim  periods  within  those  years,  and  early
adoption is permitted.  We are assessing the potential impact of ASU 2016-13 on our consolidated financial statements.  

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).  In July 2018, the FASB issued ASU 2018-
10, Codification Improvements to Topic 842, Leases, and ASU 2018-11, Targeted Improvements, both of which included a
number of technical corrections and improvements, including additional options for transition.  The new standard establishes
a right-of-use, or ROU, model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all
leases with terms longer than 12 months.  Leases will be classified as either finance or operating, with classification affecting
the  pattern  of  expense  recognition  in  the  income  statement.   ASU  2016-02  is  effective  for  annual  periods  beginning  after
December 15, 2018, including interim periods within those annual periods, with early adoption permitted.  The amendments
in ASU 2016-02 must be applied to all leases existing at the date a company initially applies the standard.  A company may
choose to use either the effective date of ASU 2016-02, or the beginning of the earliest comparative period presented in the
financial statements, as its date of initial application.  We adopted the new standard on January 1, 2019 and used the effective
date  as  the  date  of  initial  application.    Our  financial  statements  will  not  be  updated,  and  the  disclosures  under  the  new
standard will not be provided, for periods before January 1, 2019. 

ASU 2016-02 provides optional practical expedients companies can elect to use in transition.  We expect to elect
practical expedients which allow us not to reassess prior conclusions about lease identification, lease classification and initial
direct costs made under previous accounting standards.  We are continuing to evaluate the effect of adoption of ASU 2016-
02,  and  we  estimate  that  both  assets  and  liabilities  will  increase  by  $2.0  million  to  $2.5  million  upon  adoption,  before
considering deferred taxes.  We do not expect the adoption of ASU 2016-02 to have a material impact on our consolidated
statement of operations or cash flows. 

In  May  2014,  the  FASB  issued  ASU  2014-09,  Revenue  from  Contracts  with  Customers  (Topic  606).    Under  this
ASU, entities should recognize revenue in an amount that reflects the consideration to which they expect to be entitled to in
exchange  for  goods  and  services  provided.    ASU  2014-09  was  effective  for  annual  reporting  periods  beginning  after
December  15,  2017.    We  adopted  the  provisions  of  this  standard  on  January  1,  2018,  using  the  modified  retrospective
transition method.  We did not recognize any transition adjustments as a result of adopting ASU 2014-09 and, accordingly,
comparative information has not been restated for the periods reported. 

Emerging Growth Company Status

The Jumpstart Our Business Startups Act of 2012, or the 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 until those standards would otherwise apply to private companies. We have irrevocably elected to “opt out” of this
provision and, as a result, we will comply with new or revised accounting standards when they are required to be adopted by
public companies that are not emerging growth companies.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk related to changes in interest rates.  Our cash equivalents and marketable securities
consist of money market funds, asset-backed securities, commercial paper, corporate debt securities and government agency
debt. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S.
interest rates.  Our marketable securities are subject to interest rate risk and will fall in value if market interest rates increase.
However, due to the short-term nature and low-risk profile of our investment portfolio, we do not expect that an immediate
10% change in market interest rates would have a material effect on the fair market value of our investment portfolio.  We
have the ability to hold our marketable securities until maturity, and therefore we would not expect our operating results or
cash flows to be affected to any significant degree by the effect of a change in market interest rates on our investments.

The Loan and Security Agreement with Oxford provides for an annual interest rate equal to the greater of (i) 8.35%
and (ii) the 30-day U.S. LIBOR rate plus 6.25%.  To the extent that any present or future credit facilities that we enter into
are  based  on  a  floating  interest  rate,  we  will  be  subject  to  risks  relating  to  changes  in  market  interest  rates.    In  periods  of
rising  interest  rates  when  we  have  such  debt  outstanding,  our  interest  expense  would  increase.    Based  upon  our  debt
outstanding under the Loan and Security Agreement of $30.0 million as of December 31, 2018, a 100 basis-point increase in
the  interest  rate  on  our  loan  with  Oxford  would  result  in  approximately  $304,000  of  additional  interest  expense  on  an
annualized basis.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Aclaris Therapeutics, Inc.

Opinion on the Financial Statements

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

Basis for Opinion

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

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

/s/ PricewaterhouseCoopers LLP
Philadelphia, Pennsylvania
March 18, 2019

We have served as the Company’s auditor since 2015.

became  a  wholly-owned  subsidiary  thereof  (see  Note  3).    Aclaris  Therapeutics,  Inc.,  ATIL,  Vixen  and  Confluence  are
referred  to  collectively  as  the  “Company”.    The  Company  is  a  physician-led  biopharmaceutical  company  focused  on
dermatological and immuno-inflammatory diseases.  The Company has two commercial products and a diverse pipeline of
drug  candidates.  The  Company’s  first  commercial  product,  ESKATA  (hydrogen  peroxide)  Topical  Solution,  40%  (w/w)
(“ESKATA”), is a proprietary high‑concentration formulation of hydrogen peroxide that the Company is commercializing as
an  office-based  prescription  treatment  for  raised  seborrheic  keratosis  (“SK”),  a  common  non‑malignant  skin  tumor.  The
Company submitted a New Drug Application (“NDA”) for ESKATA to the U.S. Food and Drug Administration (“FDA”) in
February  2017,  and  it  was  approved  in  December  2017.    The  Company  launched  ESKATA  in  the  United  States  in  May
2018.    In  November  2018,  the  Company  acquired  the  worldwide  rights  to  a  second  commercial  product,  RHOFADE
(oxymetazoline hydrochloride) cream, 1% (“RHOFADE”) (see Note 3).    

Liquidity

The  Company’s  consolidated  financial  statements  have  been  prepared  on  the  basis  of  continuity  of  operations,
realization of assets and the satisfaction of liabilities in the ordinary course of business.  At December 31, 2018, the Company
had cash, cash equivalents and marketable securities of $167,972 and an accumulated deficit of $292,173. Since inception,
the Company has incurred net losses and negative cash flows from its operations.  Prior to the acquisition of Confluence in
August 2017, the Company had never generated any revenue.  There can be no assurance that profitable operations will ever
be  achieved,  and,  if  achieved,  will  be  sustained  on  a  continuing  basis.  In  addition,  development  activities,  clinical  and
preclinical  testing  of  the  Company’s  drug  candidates,  and  commercialization  of  ESKATA  and  RHOFADE  will  require
significant  additional  financing.    The  future  viability  of  the  Company  is  dependent  on  its  ability  to  generate  cash  from
operating activities or to raise additional capital to finance its operations.  The Company’s failure to raise capital as and when
needed could have a negative impact on its financial condition and ability to pursue its business strategies.  

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles
generally  accepted  in  the  United  States  (“GAAP”).    The  consolidated  financial  statements  of  the  Company  include  the
accounts of the operating parent company, Aclaris Therapeutics, Inc., and its wholly-owned subsidiaries, Confluence, ATIL
and Vixen.  All significant intercompany transactions have been eliminated. 

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  GAAP  requires  management  to  make  estimates  and
assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the
date of the financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and
assumptions  reflected  in  these  financial  statements  include,  but  are  not  limited  to,  research  and  development  expenses,
contingent consideration and the valuation of stock-based awards.  Estimates are periodically reviewed in light of changes in
circumstances, facts and experience. Actual results could differ from the Company’s estimates.

Revenue Recognition

The  Company  accounts  for  revenue  in  accordance  with  Accounting  Standards  Codification  (“ASC”)  Topic  606,
Revenue from Contracts with Customers.  Under ASC Topic 606, revenue is recognized when a customer obtains control of
promised  goods  or  services  in  an  amount  that  reflects  the  consideration  to  which  the  Company  expects  to  be  entitled  in
exchange for those goods or services. 

To  determine  revenue  recognition  in  accordance  with  ASC  Topic  606,  the  Company  performs  the  following  five
steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the
transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue
when  (or  as)  performance  obligations  are  satisfied.    At  contract  inception,  the  Company  assesses  the  goods  or  services
promised within a contract with a customer to identify the performance obligations, and to determine if they are distinct.  The
Company  recognizes  the  revenue  that  is  allocated  to  each  distinct  performance  obligation  when  (or  as)  that  performance
obligation is satisfied.  The Company only recognizes revenue when collection of the consideration it is entitled to under a
contract  with  a  customer  is  probable.    The  Company  expenses  incremental  costs  of  contracts  with  direct  and  indirect
customers, which generally include sales commissions, in the period they are incurred. 

Product Sales, net

The Company sells ESKATA and RHOFADE to a limited number of wholesalers in the United States (collectively,
its “Customers”).  These Customers subsequently resell the Company’s products to pharmacies and health care providers.  In
addition to distribution agreements with Customers, the Company may enter into arrangements with health care providers,
third-party payors, pharmacy benefit managers, and group purchasing organizations (“GPOs”) which provide for government
mandated  and/or  privately  negotiated  rebates,  chargebacks,  and  discounts,  with  respect  to  the  purchase  of  the  Company’s
products. 

The Company recognizes revenue from product sales at the point the Customer obtains control of the product, which
generally  occurs  upon  delivery,  and  includes  estimates  of  variable  consideration  in  the  same  period  revenue  is
recognized.    Components  of  variable  consideration  include  trade  discounts  and  allowances,  product  returns,  government
rebates, discounts and rebates, other incentives such as patient co-pay assistance, and other fee for service amounts.  Variable
consideration  is  recorded  on  the  consolidated  balance  sheet  as  either  a  reduction  of  accounts  receivable,  if  payable  to  a
customer,  or  as  a  current  liability,  if  payable  to  a  third-party  other  than  a  customer.    The  Company  considers  all  relevant
information when estimating variable consideration such as current contractual and statutory requirements, specific known
market events and trends, industry data and forecasted customer buying and payment patterns.  The amount of net revenue
the  Company  can  recognize  is  constrained  by  estimates  of  variable  consideration  which  are  included  in  the  transaction
price.  Payment terms with Customers do not exceed one year and, therefore, the Company does not account for a financing
component in its arrangements.  The Company expenses incremental costs of obtaining a contract with a Customer, including
sales  commissions,  when  incurred  as  the  period  of  benefit  is  less  than  one  year.  Shipping  and  handling  costs  for  product
shipments to Customers are recorded as sales and marketing expenses in the consolidated statement of operations. 

Trade Discounts and Allowances - The Company may provide Customers with trade discounts, rebates, allowances
or  other  incentives.    The  Company  records  an  estimate  for  these  items  as  a  reduction  of  revenue  in  the  same  period  the
revenue is recognized. 

Government  and  Payor  Rebates  -  The  Company  may  contract  with  certain  third-party  payors,  primarily  health
insurance  companies,  pharmacy  benefit  managers  and  government  programs,  for  the  payment  of  rebates  with  respect  to
utilization of its products.  The Company also has agreements with GPOs that provide for administrative fees and discounted
pricing  in  the  form  of  volume-based  rebates.    The  Company  is  also  subject  to  discount  obligations  under  state  Medicaid
programs and Medicare.  The Company records an estimate for these rebates as a reduction of revenue in the same period the
revenue is recognized. 

Other Incentives - Other incentives includes the Company’s co-pay assistance program which is intended to provide

financial assistance to qualified commercially-insured patients with prescription drug co-payments required by

104

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

payors.    The  Company  estimates  and  records  an  accrual  for  these  incentives  as  a  reduction  of  revenue  in  the  period  the
revenue is recognized.   The Company estimates amounts for co-pay assistance based upon the number of claims and the cost
per claim that the Company expects to receive associated with product that has been sold to Customers but remains in the
distribution channel at the end of each reporting period. 

Product  Returns  -  Consistent  with  industry  practice,  the  Company  has  a  product  returns  policy  that  provides
Customers  a  right  of  return  for  product  purchased  within  a  specified  period  prior  to  and  subsequent  to  the  product’s
expiration date. The right of return lapses upon shipment of the goods to a patient.  The Company records an estimate for the
amount of its products which may be returned as a reduction of revenue in the period the related revenue is recognized. The
Company’s estimates for product returns are based upon available industry data and its own sales information, including its
visibility  into  the  inventory  remaining  in  the  distribution  channel.    There  is  no  returns  liability  associated  with  sales  of
ESKATA as the Company has a no returns policy for this product.

The  Company  earns  contract  research  revenue  from  the  provision  of  laboratory  services  to  clients  through
Confluence, its wholly-owned subsidiary.  Contract research revenue is generally evidenced by contracts with clients which
are on an agreed upon fixed-price, fee-for-service basis and are generally billed on a monthly basis in arrears for services
rendered.  Revenue related to these contracts is generally recognized as the laboratory services are performed, based upon the
rates  specified  in  the  contracts.    Under  ASC  Topic  606,  the  Company  elected  to  apply  the  “right  to  invoice”  practical
expedient when recognizing contract research revenue.  The Company recognizes contract research revenue in the amount to
which it has the right to invoice. 

The Company has also received revenue from grants under the Small Business Innovation Research program of the
National Institutes of Health (“NIH”).  During the year ended December 31, 2018, the Company had two active grants from
NIH which were related to early-stage research.  As of December 31, 2018, there were no remaining funds available to the
Company under the grants.  The Company recognizes revenue related to grants as amounts become reimbursable under each
grant, which is generally when research is performed, and the related costs are incurred. 

Other Revenue

Licenses of Intellectual Property  –  The  Company  recognizes  revenue  received  from  non-refundable,  upfront  fees
related  to  the  licensing  of  intellectual  property  when  the  intellectual  property  is  determined  to  be  distinct  from  the  other
performance obligations identified in the arrangement, the license has been transferred to the customer, and the customer is
able to use and benefit from the license. 

Milestone  Payments  -  At  the  inception  of  each  arrangement  that  includes  milestone  payments,  the  Company
evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the
transaction price using the most likely amount method.  If it is probable that a significant revenue reversal would not occur,
the associated milestone value is included in the amount allocated to the license of intellectual property.  Milestone payments
that are not within the control of the Company or the customer, such as regulatory approvals, are not considered probable of
being achieved until those approvals are received.

Cash Equivalents

The  Company  considers  all  short  term,  highly  liquid  investments  with  original  maturities  of  90  days  or  less  at
acquisition date to be cash equivalents. Cash equivalents, which have consisted of money market accounts, commercial paper
and corporate debt securities with original maturities of less than three months, are stated at fair value. 

Marketable Securities

Marketable securities with original maturities of greater than three months and remaining maturities of less than one
year from the balance sheet date are classified as short term. Marketable securities with remaining maturities of greater than
one year from the balance sheet date are classified as long term. 

The Company classifies all of its marketable securities as available-for-sale securities. The Company’s marketable
securities are measured and reported at fair value using quoted prices in markets that are not active for identical or similar
securities. Unrealized gains and losses are reported as a separate component of stockholders’ equity. The cost of securities
sold is determined on a specific identification basis, and realized gains and losses, if any, are included in other income, net
within the consolidated statement of operations and comprehensive loss. If any adjustment to fair value reflects a decline in
the value of the investment, the Company considers available evidence to evaluate the extent to which the decline is “other
than temporary” and reduces the investment to fair value through a charge to the statement of operations and comprehensive
loss. 

Other Assets

In February 2017, the Company paid a $2,000 PDUFA fee to the FDA in conjunction with the filing of its NDA for
ESKATA.  The Company requested a waiver and refund of this PDUFA fee, which was approved by the FDA in December
2017, and was refunded to the Company in January 2018. 

Inventory

Inventory includes the third-party cost of manufacturing and assembly of finished product, quality control and other
overhead  costs.    Inventory  is  stated  at  the  lower  of  cost  or  net  realizable  value.    Inventory  is  adjusted  for  short-dated,
unmarketable  inventory  equal  to  the  difference  between  the  cost  of  inventory  and  the  estimated  value  based  upon
assumptions about future demand and market conditions.  The Company had $791 and $0 of inventory as of December 31,
2018 and 2017, respectively, which was comprised primarily of finished goods.  

Deferred Offering Costs

The  Company  recorded  legal,  accounting  and  other  third-party  fees  associated  directly  with  the  filing  of  its
registration  statement  on  Form  S-3  in  November  2016,  in  other  assets  on  its  consolidated  balance  sheet.    These  deferred
offering  costs  are  recorded  in  stockholders’  equity  as  a  reduction  of  the  proceeds  generated  from  offerings  consummated
under the Form S-3 on a pro rata basis.  The Company may also record legal, accounting and other third-party fees directly
associated  with  in-process  equity  financings  as  deferred  offering  costs  (non-current)  until  such  financings  are
completed.  The deferred costs related to an in-process equity financing are recorded in stockholders’ equity as a reduction of
the  proceeds  generated  from  the  related  offering  when  it  is  completed.    Deferred  offering  costs  were  $0  and  $62  as  of
December 31, 2018 and 2017, respectively. 

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation expense is recognized using
the straight-line method over the useful life of the asset. Computer equipment is depreciated over three years. Manufacturing
and laboratory equipment is depreciated over five years. Furniture and fixtures are depreciated over five years.  Leasehold
improvements are depreciated over the shorter of the lease term or their useful life.  Expenditures for repairs and maintenance
of assets are charged to expense as incurred. Upon retirement or sale, the cost and related accumulated depreciation of assets
disposed of are removed from the accounts and any resulting gain or loss is included in loss from operations.

Assets Held for Sale

In order for an asset to be classified as held for sale, several criteria must be achieved.  These criteria include, among
others, an active program to market an asset and locate a buyer, as well as the probable disposition of the asset within one
year.    Upon  being  classified  as  held  for  sale,  the  recoverability  of  the  carrying  value  of  an  asset  must  be  assessed  and
evaluated.  After the valuation process is completed, the held for sale asset is reported at the lower of its carrying value or fair
value less cost to sell, and no additional depreciation expense is recognized related to the asset.  Once an asset is classified as
held  for  sale,  all  of  its  historical  balance  sheet  information  is  included  in  prepaid  expenses  and  other  current  assets  in  the
accompanying  consolidated  balance  sheets.  The  Company  recorded  an  impairment  charge  of  $216  in  the  year  ended
December 31, 2016 for equipment that was previously classified as held for sale.  The impairment charge was included in
research  and  development  expense  on  the  Company’s  consolidated  statement  of  operations.    The  Company  had  no  assets
classified as held for sale as of December 31, 2018 and 2017. 

Impairment of Long Lived Assets

Long-lived  assets  consist  of  property  and  equipment.  Long-lived  assets  to  be  held  and  used  are  tested  for
recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not
be  fully  recoverable.  Factors  that  the  Company  considers  in  deciding  when  to  perform  an  impairment  review  include
significant underperformance of the business in relation to expectations, significant negative industry or economic trends and
significant changes or planned changes in the use of the assets. If an impairment review is performed to evaluate a long lived
asset  for  recoverability,  the  Company  compares  forecasts  of  undiscounted  cash  flows  expected  to  result  from  the  use  and
eventual disposition of the long lived asset to its carrying value. An impairment loss would be recognized when estimated
undiscounted future cash flows expected to result from the use of an asset are less than its carrying amount. The impairment
loss  would  be  based  on  the  excess  of  the  carrying  value  of  the  impaired  asset  over  its  fair  value,  determined  based  on
discounted cash flows. 

Intangible Assets

Intangible  assets  include  both  finite-lived  and  indefinite-lived  assets.    Finite-lived  intangible  assets  are  amortized
over their estimated useful life based on the pattern over which the intangible assets are consumed or otherwise used up. If
that  pattern  cannot  be  reliably  determined,  the  straight-line  method  of  amortization  is  used.    Finite-lived  intangible  assets
consist of a research technology platform the Company acquired through the acquisition of Confluence and the intellectual
property rights related to RHOFADE.  Indefinite-lived intangible assets consist of an in-process research and development
(“IPR&D”)  drug  candidate  acquired  through  the  acquisition  of  Confluence.    IPR&D  assets  are  considered  indefinite-lived
until the completion or abandonment of the associated research and development efforts.  The cost of IPR&D assets is either
amortized  over  their  estimated  useful  life  beginning  when  the  underlying  drug  candidate  is  approved  and  launched
commercially, or expensed immediately if development of the drug candidate is abandoned. 

Finite-lived intangible assets are tested for impairment when events or changes in circumstances indicate that the
carrying  value  of  the  asset  may  not  be  recoverable.    Indefinite-lived  intangible  assets  are  tested  for  impairment  at  least
annually,  which  the  Company  performs  during  the  fourth  quarter,  or  when  indicators  of  an  impairment  are  present.    The
Company recognizes impairment losses when and to the extent that the estimated fair value of an indefinite-lived intangible
asset is less than its carrying value. 

Goodwill

Goodwill  is  not  amortized,  but  rather  is  subject  to  testing  for  impairment  at  least  annually,  which  the  Company
performs  during  the  fourth  quarter,  or  when  indicators  of  an  impairment  are  present.   The  Company  considers  each  of  its
operating segments, dermatology therapeutics and contract research, to be a reporting unit since this is the lowest level for
which discrete financial information is available.  The Company has attributed the full amount of the goodwill acquired with
Confluence, or $18,504, to the dermatology therapeutics segment.  The annual impairment test performed by the Company is
a  qualitative  assessment  based  upon  current  facts  and  circumstances  related  to  operations  of  the  dermatology  therapeutics
segment.  If the qualitative assessment indicates an impairment may be present, the Company would perform the required
quantitative  analysis  and  an  impairment  charge  would  be  recognized  to  the  extent  that  the  estimated  fair  value  of  the
reporting unit is less than its carrying amount.  However, any loss recognized would not exceed the total amount of goodwill
allocated to that reporting unit.  The Company concluded goodwill was not impaired as of December 31, 2018 and 2017.

Contingent Consideration

The  Company  initially  recorded  the  contingent  consideration  related  to  future  potential  payments  based  upon  the
achievement of certain development, regulatory and commercial milestones, resulting from the acquisition of Confluence, at
its estimated fair value on the date of acquisition.  Changes in fair value reflect new information about the likelihood of the
payment  of  the  contingent  consideration  and  the  passage  of  time.    Future  changes  in  the  fair  value  of  the  contingent
consideration, if any, will be recorded as income or expense in the Company’s consolidated statement of operations. 

Research and Development Costs

Research  and  development  costs  are  expensed  as  incurred.  Research  and  development  expenses  include  salaries,
stock-based  compensation  and  benefits  of  employees,  fees  paid  under  licensing  agreements,  fees  paid  under  a  third  party
assignment agreement and other operational costs related to the Company’s research and development activities, including
depreciation expenses and the cost of research and development contracts which the Company has entered into with outside
vendors to conduct both preclinical studies and clinical trials.  Significant judgment and estimates are made in determining
the amount of research and development costs recognized in each reporting period.  The Company analyzes the progress of
its  preclinical  studies  and  clinical  trials,  completion  of  milestone  events,  invoices  received  and  contracted  costs  when
estimating  research  and  development  costs.  Actual  results  could  differ  from  the  Company’s  estimates.  The  Company’s
historical estimates for research and development costs have not been materially different from the actual costs.

Stock-Based Compensation

The Company measures the compensation expense of stock-based awards granted to employees and directors using
the grant date fair value of the award.  The Company has issued stock options and restricted stock unit (“RSU”) awards with
service-based vesting conditions, as well as with performance-based vesting conditions.  The Company has not issued awards
that include market-based conditions.  For service-based awards the Company recognizes stock-based compensation expense
on a straight-line basis over the requisite service period.  For performance-based awards the Company recognizes stock-based
compensation  expense  on  a  straight-line  basis  over  the  requisite  service  period  beginning  in  the  period  that  it  becomes
probable  the  performance  conditions  will  occur.    At  each  balance  sheet  date,  the  Company  evaluates  whether  any
performance  conditions  related  to  a  performance-based  award  have  changed.    The  effect  of  any  change  in  performance
conditions would be recognized as a cumulative catch-up adjustment in the period such change occurs, and any remaining
unrecognized  compensation  expense  would  be  recognized  on  a  straight-line  basis  over  the  remaining  requisite  service
period.  The impact of forfeitures is recognized in the period in which they occur. 

The Company initially measures the compensation expense of stock-based awards granted to consultants using the
grant date fair value of the award. Compensation expense is recognized over the period during which services are rendered
by  such  consultants.  At  the  end  of  each  financial  reporting  period  prior  to  completion  of  services  being  rendered,  the
compensation  expense  related  to  these  awards  is  remeasured  using  the  then  current  fair  value  of  the  Company’s  common
stock for RSUs, or based upon updated assumptions in the Black-Scholes option pricing model for stock option awards. 

The Company classifies stock-based compensation expense in its statement of operations and comprehensive loss in
the  same  manner  in  which  the  award  recipient’s  payroll  costs  are  classified  or  in  which  the  award  recipients’  service
payments are classified. 

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing
model.  The  Company  estimates  its  expected  stock  volatility  based  on  the  historical  volatility  of  a  set  of  peer  companies,
which are publicly traded, and expects to continue to do so until it has adequate historical data regarding the volatility of its
own  publicly-traded  stock  price.  The  expected  term  of  the  Company’s  stock  options  has  been  determined  using  the
“simplified” method for awards that qualify as “plain vanilla” options. The expected term of stock options granted to non-
employees is equal to the contractual term of the option award. The risk-free interest rate is determined by reference to the
U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected
term of the award. The Company uses an expected dividend yield of zero based on the fact that the Company has never paid
cash  dividends  and  does  not  expect  to  pay  cash  dividends  in  the  future.    Prior  to  the  Company’s  initial  public  offering  in
October 2015 (“IPO”), the Company valued its common stock using a hybrid method to estimate its enterprise value.  The
hybrid method used was a probability-weighted expected return method which was a scenario-based methodology

108

 
 
 
 
 
 
 
 
 
 
Table of Contents

that  estimated  the  fair  value  of  the  Company’s  common  stock  based  upon  an  analysis  of  future  values  for  the  Company
assuming various outcomes.  The hybrid method used calculated equity values using an option pricing model in one or more
of scenarios, and also considered the rights of each class of stock. 

The  fair  value  of  each  RSU  is  measured  using  the  closing  price  of  the  Company’s  common  stock  on  the  date  of

grant.

Patent Costs

All  patent  related  costs  incurred  in  connection  with  filing  and  prosecuting  patent  applications  are  expensed  as
incurred  due  to  the  uncertainty  about  the  recovery  of  the  expenditure.    Amounts  incurred  are  classified  as  general  and
administrative expenses.

Foreign Currency Translation

The reporting currency of the Company is the U.S. Dollar. The functional currency of ATIL, the Company’s wholly-
owned  subsidiary,  is  the  British  Pound.   Assets  and  liabilities  of  ATIL  are  translated  into  U.S.  Dollars  based  on  exchange
rates at the end of each reporting period. Revenues and expenses are translated at average exchange rates during the reporting
period.  Gains and losses arising from the translation of assets and liabilities are included as a component of accumulated
other  comprehensive  loss  within  the  Company’s  consolidated  balance  sheet.    Gains  and  losses  resulting  from  foreign
currency  transactions  are  reflected  within  the  Company’s  consolidated  statement  of  operations.    The  Company  has  not
utilized foreign currency hedging strategies to mitigate the effect of its foreign currency exposure.

Income Taxes

The  Company  accounts  for  income  taxes  using  the  asset  and  liability  method,  which  requires  the  recognition  of
deferred  tax  assets  and  liabilities  for  the  expected  future  tax  consequences  of  events  that  have  been  recognized  in  the
financial  statements  or  in  the  Company’s  tax  returns.  Deferred  taxes  are  determined  based  on  the  difference  between  the
financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences
are  expected  to  reverse.  Changes  in  deferred  tax  assets  and  liabilities  are  recorded  in  the  provision  for  income  taxes.  The
Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it
believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax
assets  will  not  be  realized,  a  valuation  allowance  is  established  through  a  charge  to  income  tax  expense.  Potential  for
recovery  of  deferred  tax  assets  is  evaluated  by  estimating  the  future  taxable  profits  expected  and  considering  prudent  and
feasible tax planning strategies.

The  Company  accounts  for  uncertainty  in  income  taxes  recognized  in  the  consolidated  financial  statements  by
applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated
to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is
deemed more likely than not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize
in the consolidated financial statements. The amount of the benefit that may be recognized is the largest amount that has a
greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of
any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and
penalties.

Comprehensive Loss

Comprehensive  loss  includes  net  loss  as  well  as  other  changes  in  stockholders’  equity  (deficit)  that  result  from
transactions and economic events other than those with stockholders.  Comprehensive loss is comprised of net loss, foreign
currency translation adjustments and unrealized gains (losses) on marketable securities.

Net Loss per Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the
period.  Diluted net loss per share is computed using the sum of the weighted average number of common shares outstanding
during the period, plus the weighted average number of potential shares of common stock from the assumed exercise of stock
options, and the assumed vesting of RSUs and restricted stock granted by the Company upon its formation, if dilutive.  Since
the Company was in a net loss position basic and diluted net loss per share was the same for each of the periods presented. 

Fair Value Measurements

Certain assets and liabilities are carried at fair value under GAAP.  Fair value is defined as the exchange price that
would  be  received  for  an  asset  or  paid  to  transfer  a  liability  in  the  principal  or  most  advantageous  market  for  the  asset  or
liability  in  an  orderly  transaction  between  market  participants  on  the  measurement  date.  Valuation  techniques  used  to
measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets
and  liabilities  carried  at  fair  value  are  to  be  classified  and  disclosed  in  one  of  the  following  three  levels  of  the  fair  value
hierarchy, of which the first two are considered observable and the last is considered unobservable:

·

·

·

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

Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for
similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or
liabilities, or other inputs that are observable or can be corroborated by observable market data.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to
determining the fair value of the assets or liabilities, including pricing models, discounted cash flow
methodologies and similar techniques.

The  Company’s  cash  equivalents,  marketable  securities  and  contingent  consideration  are  carried  at  fair  value,
determined according to the fair value hierarchy described above.  The carrying value of the Company’s accounts payable
and  accrued  expenses  approximate  fair  value  due  to  the  short-term  nature  of  these  liabilities.    The  carrying  value  of  the
Company’s  debt  approximates  fair  value  because  interest  is  a  floating  rate  based  on  the  30-day  U.S.  LIBOR  rate,  and  is
therefore reflective of market rates. 

Concentration of Credit Risk and of Significant Customers and Suppliers

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash,
cash equivalents and marketable securities. The Company holds all cash, cash equivalents and marketable securities balances
at one accredited financial institution, in amounts that exceed federally insured limits. The Company does not believe that it
is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. 

The  Company’s  top  five  customers  represented  83%  of  aggregate  gross  revenue  from  product  sales  and  contract
research  revenue  for  the  year  ended  December  31,  2018.    The  Company’s  top  five  customers  represented  70%  of  total
contract  research  revenue  earned  from  August  3,  2017,  the  date  of  acquisition  of  Confluence,  through  December  31,
2017.  The Company did not have product sales during the year ended December 31, 2017. 

The Company is dependent on third party manufacturers to supply products for commercial distribution, as well as
for  research  and  development  activities,  including  preclinical  and  clinical  testing.    These  activities  could  be  adversely
affected by a significant interruption in the supply of active pharmaceutical ingredients and other components.

Segment Reporting

Operating  segments  are  components  of  a  company  for  which  separate  financial  information  is  available  and
evaluated  regularly  by  the  chief  operating  decision  maker  in  assessing  performance  and  deciding  how  to  allocate
resources.  The Company reports two segments, dermatology therapeutics and contract research, which are primarily based
on  its  operating  segments  and  operating  results  used  to  assess  performance.    The  dermatology  therapeutics  segment  is
focused  on  dermatological  and  immuno-inflammatory  diseases.    The  contract  research  segment  is  focused  on  providing
laboratory services to pharmaceutical and biotech companies looking to supplement their research and development efforts
with difficult-to-execute specialty skills and programs.  The Company does not allocate assets by segment. 

Recently Issued and Adopted Accounting Pronouncements

In  November  2018,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  Accounting  Standards  Update
(“ASU”) 2018-18, Collaborative Arrangements (Topic 808):  Clarifying the Interaction Between Topic 808 and Topic 606,
which,  among  other  things,  provides  guidance  on  how  to  assess  whether  certain  collaborative  arrangement  transactions
should be accounted for under Topic 606.  The amendments in this ASU are effective for fiscal years, and interim periods
within those fiscal years, beginning after December 15, 2019, with early adoption permitted.  The Company is evaluating the
impact of ASU 2018-18 on its consolidated financial statements. 

In  August  2018,  the  FASB  issued  ASU  2018-15,  Intangibles—Goodwill  and  Other—Internal-Use  Software
(Subtopic 350-40).  ASU 2018-15 requires a customer in a cloud computing arrangement that is a service contract to follow
the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense
as  incurred.   The  standard  will  be  effective  for  fiscal  years  beginning  after  December  15,  2019,  including  interim  periods
within  such  fiscal  years,  with  early  adoption  permitted.    The  Company  is  evaluating  the  impact  of  ASU  2018-15  on  its
consolidated financial statements. 

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820).  The FASB developed the
amendments  to  ASC  820  as  part  of  its  broader  disclosure  framework  project,  which  aims  to  improve  the  effectiveness  of
disclosures  in  the  notes  to  financial  statements  by  focusing  on  requirements  that  clearly  communicate  the  most  important
information  to  users  of  the  financial  statements.    This  update  eliminates  certain  disclosure  requirements  for  fair  value
measurements for all entities, requires public entities to disclose certain new information and modifies some of the existing
disclosure requirements.  The standard will be effective for fiscal years beginning after December 15, 2019, including interim
periods within such fiscal years, with early adoption permitted.  The Company is evaluating the impact of ASU 2018-13 on
its consolidated financial statements. 

In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718).  The amendments
in this ASU expand the scope of Topic 718 to include stock-based compensation arrangements with nonemployees except for
specific guidance on option pricing model inputs and cost attribution.  ASU 2018-07 is effective for annual reporting periods
beginning  after  December  31,  2018,  including  interim  periods  within  that  year,  and  early  adoption  is  permitted.    The
Company  adopted  the  provisions  of  this  standard  on  January  1,  2019,  the  impact  of  which  on  its  consolidated  financial
statements was not significant. 

In January 2017, the FASB issued ASU 2017-01, Business Combinations—Clarifying the Definition of a Business
(Topic 805).    The amendments in this ASU provide a screen to determine when a set of acquired assets and/or activities is
not a business.  The screen requires that when substantially all of the fair value of the gross assets acquired, or disposed of, is
concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business.  The amendments
in  this  ASU  will  reduce  the  number  of  transactions  that  meet  the  definition  of  a  business.   ASU  2017-01  is  effective  for
annual reporting periods beginning after December 15, 2017, including interim periods within those years, and early adoption
is  permitted.    The  Company  adopted  the  provisions  of  this  standard  on  January  1,  2018,  the  impact  of  which  on  its
consolidated financial statements was not significant. 

In  June  2016,  the  FASB  issued  ASU  2016-13,  Financial  Instruments—Credit  Losses  (Topic  326).    This  ASU
introduces  a  new  model  for  recognizing  credit  losses  on  financial  instruments  based  upon  estimated  expected  credit
losses.  ASU 2016-13 will apply to loans, accounts receivable, financial assets measured at amortized cost and at fair value
through  other  comprehensive  income,  loan  commitments  and  certain  off-balance  sheet  credit  exposures.   ASU  2016-13  is
effective for annual reporting periods beginning after December 15, 2019, including interim periods within those years, and
early adoption is permitted.  The Company is assessing the potential impact of ASU 2016-13 on its consolidated financial

111

statements. 

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).  In July 2018, the FASB issued ASU 2018-
10,  Codification  Improvements  to  Topic  842,  Leases,  and  2018-11,  Targeted  Improvements,  which  included  a  number  of
technical corrections and improvements, including additional options for transition.  The new standard establishes a right-of-
use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with
terms longer than 12 months.  Leases will be classified as either finance or operating, with classification affecting the pattern
of expense recognition in the income statement.  ASU 2016-02 is effective for annual periods beginning after December 15,
2018, including interim periods within those annual periods, with early adoption permitted.  The amendments in ASU 2016-
02 must be applied to all leases existing at the date a company initially applies the standard.  A company may choose to use
either  the  effective  date  of  ASU  2016-02,  or  the  beginning  of  the  earliest  comparative  period  presented  in  the  financial
statements,  as  its  date  of  initial  application.    The  Company  adopted  the  new  standard  on  January  1,  2019  and  used  the
effective date as its date of initial application.  The Company’s financial statements will not be updated, and the disclosures
under the new standard will not be provided, for periods before January 1, 2019. 

ASU 2016-02 provides optional practical expedients companies can elect to use in transition.  The Company expects
to elect practical expedients which allow it not to reassess prior conclusions about lease identification, lease classification and
initial direct costs made under previous accounting standards.  The Company continues to evaluate the effect of adoption of
ASU 2016-02, and estimates both assets and liabilities will increase by $2,000 to $2,500 upon adoption, before considering
deferred taxes.  The Company does not expect the adoption of ASU 2016-02 will have a material impact on its consolidated
statement of operations or cash flows. 

In  May  2014,  the  FASB  issued  ASU  2014-09,  Revenue  from  Contracts  with  Customers  (Topic  606).    Under  this
ASU, entities should recognize revenue in an amount that reflects the consideration to which they expect to be entitled to in
exchange  for  goods  and  services  provided.    ASU  2014-09  was  effective  for  annual  reporting  periods  beginning  after
December 15, 2017.  The Company did not recognize any transition adjustments as a result of adopting ASU 2014-09 and,
accordingly, comparative information has not been restated for the periods reported.   

3. Acquisitions

RHOFADE

In November 2018, the Company completed the acquisition of RHOFADE from Allergan Sales, LLC (“Allergan”)
pursuant to the Asset Purchase Agreement dated as of October 15, 2018 (the “APA”).  Pursuant to the APA, the Company
acquired  the  worldwide  rights  to  RHOFADE,  which  includes  an  exclusive  license  to  certain  intellectual  property  for
RHOFADE, as well as additional intellectual property. 

The following table summarizes the aggregate amount paid for the assets acquired by the Company in connection

with the acquisition of RHOFADE: 

Cash paid to Allergan at closing
Cash deposited in escrow at closing
Transaction costs
    Total purchase price of assets acquired

$

$

59,574  
6,500  
1,048  
67,122  

The Company has also agreed to pay Allergan a one-time payment of $5,000 upon the achievement of a specified
development milestone related to the potential development of an additional dermatology product.  In addition, the Company
has agreed to pay Allergan specified royalties, ranging from a mid-single digit percentage to a mid-teen percentage of net
sales, subject to specified reductions, limitations and other adjustments, on a country-by-country basis until the date that the
patent  rights  related  RHOFADE  have  expired  or,  if  later,  November  30,  2028.    In  addition,  the  Company  has  agreed  to
assume  the  obligation  to  pay  specified  royalties  and  milestone  payments  under  agreements  with  Aspect  Pharmaceuticals,
LLC  and  Vicept  Therapeutics,  Inc.    Members  of  the  Company’s  management  team,  including  Neal  Walker,  Frank  Ruffo,
Christopher Powala and Stuart Shanler, as well as Stephen Tullman, the chairman of the Company’s board of directors, are
former  stockholders  of  Vicept  Therapeutics,  Inc.,  and  Dr.  Shanler  is  also  a  current  member  of  Aspect  Pharmaceuticals,
LLC.  In their capacities as current or former holders of equity interests in these

112

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

entities, these individuals may be entitled to receive a portion of the potential future payments payable by the Company.  The
Company incurred an aggregate expense of $165 and $0 related to royalty payments under these agreements during the years
ended December 31, 2018 and 2017, respectively. 

The acquisition of RHOFADE has been accounted for as an asset acquisition in accordance with FASB ASC 805-50,
rather  than  as  a  business  combination.   As  an  asset  acquisition,  the  cost  to  acquire  the  group  of  assets  is  allocated  to  the
individual assets acquired or liabilities assumed based on their relative fair values.  The relative fair values of identifiable
tangible  and  intangible  assets  assumed  from  the  acquisition  of  RHOFADE  are  based  on  estimates  of  fair  value  using
assumptions that the Company believes is reasonable.  The Company accounted for the acquisition of RHOFADE as an asset
acquisition because substantially all of the fair value of the assets acquired is concentrated in a single asset, the RHOFADE
product rights.  ASC 805-10-55-5A, which sets forth a screen test, provides that if substantially all of the fair value of the
assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, the assets acquired are not
considered to be a business. 

The following table summarizes the fair value of assets acquired in the acquisition of RHOFADE: 

Inventory
Intangible assets, net
    Total assets acquired

$

$

893  
66,229  
67,122  

The fair value of finished goods inventory acquired was estimated using net selling price less the costs of disposal
and a reasonable profit for the disposal efforts.  Raw material was valued at current replacement cost, which approximated
the seller’s carrying value.  The intangible asset for the RHOFADE product rights will be amortized on a straight-line basis
over a period of 10 years.  The Company believes this pattern of amortization reflects the expected benefits to be realized
from  commercializing  RHOFADE.    In  addition,  the  10-year  useful  life  is  based  upon  expiration  dates  of  key  patents
underlying the RHOFADE intellectual property. 

Confluence

In August 2017, the Company acquired Confluence, at which time, Confluence became a wholly-owned subsidiary
of  the  Company.    The  Company  gave  aggregate  consideration  with  a  fair  value  of  $24,322  to  the  equity  holders  of
Confluence.  The following table summarizes the fair value of total consideration given to the Confluence equity holders in
connection with the acquisition:

The Company accounted for the acquisition of Confluence as a business combination using the acquisition method
of  accounting.    Under  the  acquisition  method  of  accounting,  the  assets  acquired  and  liabilities  assumed  in  this  transaction
were recorded at their respective fair values.  The following table summarizes the fair value of assets acquired and liabilities
assumed in the acquisition of Confluence:

The  fair  value  of  the  IPR&D  and  the  other  intangible  assets  acquired  was  determined  using  a  replacement  cost
method,  which  estimated  the  cost  that  would  be  required  to  rebuild  the  intangible  assets  identified  in  the  acquisition  of
Confluence.    The  acquisition  of  Confluence  resulted  in  the  recognition  of  goodwill  in  the  amount  of  $18,504  which
represents  the  value  of  new  products  and  technologies  to  be  developed  in  the  future  as  well  as  the  value  of  the  employee
workforce acquired. 

In  November  2018,  the  Company  achieved  a  development  milestone  specified  in  the  merger  agreement  with
Confluence equity holders.  The milestone payment to the Confluence equity holders was comprised of $2,500 in cash and
253,208  shares  of  the  Company’s  common  stock  with  a  fair  value  of  $2,216.    The  Company  also  agreed  to  pay  the
Confluence  equity  holders  aggregate  additional  milestone  payments  of  up  to  $75,000,  based  upon  the  achievement  of
specified regulatory and commercial milestones.  In addition, the Company has agreed to pay the Confluence equity holders
royalty payments calculated as a low single-digit percentage of annual net sales, subject to specified reductions, limitations
and other adjustments, until the date that all of the patent rights for that product have expired, as determined on a country-by-
country  and  product-by-product  basis  or,  in  specified  circumstances,  ten  years  from  the  first  commercial  sale  of  such
product.  In addition, if the Company sells, licenses or transfers any of the intellectual property acquired from Confluence,
the Company will be obligated to pay the Confluence equity holders a portion of any incremental consideration (in excess of
the development and milestone payments described above) that the Company receives from such sales, licenses or transfers
in specified circumstances. 

The  following  supplemental  unaudited  pro  forma  information  presents  the  Company’s  financial  results,  for  the
periods  presented,  as  if  the  acquisition  of  Confluence  had  occurred  on  January  1,  2016.   This  supplemental  unaudited  pro
forma financial information has been prepared for comparative purposes only, and is not necessarily indicative of what actual
results would have been had the acquisition of Confluence occurred on January 1, 2016, nor is this information indicative of
future results.

The supplemental unaudited pro forma financial results for the year ended December 31, 2017 includes adjustments
to exclude $1,351 of acquisition-related expenses, and $888 to exclude revenue billed to the Company by Confluence.  The
supplemental unaudited pro forma financial results for the year ended December 31, 2017 also includes an adjustment for
amortization expense related to the other intangible asset acquired. 

There were no acquisition-related expenses incurred, or revenue billed to the Company by Confluence for the year
ended  December  31,  2016,  and  accordingly,  no  adjustment  is  necessary  for  these  items  in  the  supplemental  pro  forma
financial results for that year.  The supplemental unaudited pro forma financial results for the year ended December 31, 2016
includes an adjustment for amortization expense related to the other intangible assets acquired.

As  of  December  31,  2018  and  2017,  the  Company’s  cash  equivalents  consisted  of  investments  with  maturities  of
less  than  three  months  and  included  a  money  market  fund  and  commercial  paper  which  were  valued  based  upon  Level  1
inputs, and commercial paper, government obligations and corporate debt securities which were valued based upon Level 2
inputs.  In determining the fair value of its Level 2 investments the Company relied on quoted prices for identical securities
in markets that are not active. These quoted prices were obtained by the Company with the assistance of a third‑party pricing
service  based  on  available  trade,  bid  and  other  observable  market  data  for  identical  securities.    Quarterly,  the  Company
compares the quoted prices obtained from the third‑party pricing service to other available independent pricing information
to  validate  the  reasonableness  of  the  quoted  prices  provided.  The  Company  evaluates  whether  adjustments  to  third-party
pricing is necessary and, historically, the Company has not made adjustments to quoted prices obtained from the third-party
pricing service.  During the years ended December 31, 2018 and 2017, there were no transfers between Level 1, Level 2 and
Level 3.  The reduction in acquisition-related contingent consideration of $3,444 during the year ended December 31, 2018
was  primarily  due  to  the  achievement  of  a  specified  development  milestone  in  November  2018  which  resulted  in  the
Company  paying  cash  of  $2,500  and  issuing  common  stock  with  a  fair  value  of  $2,216  to  the  former  Confluence  equity
holders.  This reduction was partially offset by an adjustment of $1,272 to increase the value of the liability related to the
achievement of the specified development milestone.

Finance LLC, a Delaware limited liability company (“Oxford”).  The Loan Agreement provides for up to $65,000 in term
loans (the “Term Loan Facility”).  Of the $65,000, the Company borrowed $30,000 in October 2018.  The remaining $35,000
is available to be borrowed until the earlier of March 31, 2019 or an event of default.  Should the Company not draw all of
the Term Loan Facility, or repay the entirety of the amount drawn during the applicable draw timeframe, the Company will
be required to pay a non-utilization fee equal to 1.0% of the undrawn portion of the Term Loan Facility. 

The  Loan  Agreement  provides  for  interest  only  payments  through  November  2021,  followed  by  24  consecutive
equal monthly payments of principal and interest in arrears starting on November 2021 and continuing through the maturity
date  of  October  2023.    All  unpaid  principal  and  accrued  and  unpaid  interest  will  be  due  and  payable  on  the  maturity
date.   The  Loan  Agreement  provides  for  an  annual  interest  rate  equal  to  the  greater  of  (i)  8.35%  and  (ii)  the  30-day  U.S.
LIBOR rate plus 6.25%.  The Loan Agreement also provides for a final payment fee equal to 5.75% of the original principal
amount of the term loans drawn under the Term Loan Facility, which final payment is due on October 1, 2023 or upon the
prepayment of the facility or the acceleration of amounts due under the facility as a result of an event of default. 

The Company has the option to prepay the outstanding balance of the term loans in full, subject to a prepayment fee
of (i) 3% of the original principal amount of the aggregate term loans drawn for any prepayment prior to the first anniversary
of the date such term loan was funded, (ii) 2% of the original principal amount of the aggregate term loans drawn for any
prepayment  between  the  first  and  second  anniversaries  of  the  date  such  term  loan  was  funded  or  (iii)  1%  of  the  original
principal amount of the aggregate term loans drawn for any prepayment after the second anniversary of the funding date but
before October 1, 2023. The Company also has the option to prepay the term loans in part, once in a three-month period, of
an amount of $2,000 or greater, subject to the same prepayment fees and other specified limitations. 

The Term Loan Facility is secured by substantially all of the Company’s assets, except that the collateral does not
include  the  Company’s  intellectual  property,  and  the  Company  has  agreed  not  to  encumber  any  of  its  intellectual
property.  The Loan Agreement contains customary representations, warranties and covenants by the Company.  The Loan
Agreement also contains specified financial covenants related to minimum consolidated future revenues of the Company.

10. Stock‑Based Awards

2017 Inducement Plan

In  July  2017,  the  Company’s  board  of  directors  adopted  the  2017  Inducement  Plan  (the  “2017  Inducement
Plan”).  The 2017 Inducement Plan is a non-shareholder approved stock plan adopted pursuant to the “inducement exception”
provided under Nasdaq listing rules.  The only employees eligible to receive grants of awards under the 2017 Inducement
Plan are individuals who satisfy the standards for inducement grants under Nasdaq rules, generally including individuals who
were not previously an employee or director of the Company. Under the terms of the 2017 Inducement Plan the Company
may  grant  up  to  1,000,000  shares  of  common  stock  pursuant  to  nonqualified  stock  options,  stock  appreciation  rights,
restricted stock awards, RSUs, and other stock awards.  All shares of common stock that were eligible for issuance under the
2017  Inducement  Plan  after  October  1,  2018,  including  any  shares  underlying  any  awards  that  expire  or  are  otherwise
terminated, reacquired to satisfy tax withholding obligations, settled in cash or repurchased by the Company in the future that
would have been eligible for re-issuance under the 2017 Inducement Plan, were retired. 

2015 Equity Incentive Plan

In September 2015, the Company’s board of directors adopted the 2015 Equity Incentive Plan (the “2015 Plan”),
and the Company’s stockholders approved the 2015 Plan.  The 2015 Plan became effective in connection with the Company’s
IPO.    Beginning  at  the  time  the  2015  Plan  became  effective,  no  further  grants  may  be  made  under  the  Company’s  2012
Equity Compensation Plan, as amended and restated (the “2012 Plan”).  The 2015 Plan provides for the grant of incentive
stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, RSU awards, performance stock
awards, cash-based awards and other stock-based awards. The number of shares initially reserved for issuance under the 2015
Plan was 1,643,872 shares of common stock.  The number of shares of common stock that may be issued under the 2015 Plan
will automatically increase on January 1 of each year ending on January 1, 2025, in an amount equal to the lesser of (i) 4.0%
of the shares of the Company’s common stock outstanding on December 31 of the preceding calendar year or (ii) an amount
determined  by  the  Company’s  board  of  directors.  The  shares  of  common  stock  underlying  any  awards  that  expire,  are
otherwise terminated, settled in cash or repurchased by the Company under the 2015 Plan and the 2012 Plan will be added
back to the shares of common stock available for issuance under the 2015 Plan.  As of December 31, 2018, 1,616,362 shares
remained available for grant under the 2015 Plan.  As of January 1, 2019, the number of shares of common stock that may be
issued under the 2015 Plan was automatically increased by 1,648,429 shares. 

2012 Equity Compensation Plan

Upon the 2015 Plan becoming effective, no further grants can be made under the 2012 Plan.  The Company granted
a total of 1,140,524 stock options under the 2012 Plan, of which 948,761 and 984,720 were outstanding as of December 31,
2018 and 2017, respectively.  Stock options granted under the 2012 Plan vest over four years and expire after ten years.  As
required, the exercise price for the stock options granted under the 2012 Plan was not less than the fair value of common
shares as determined by the Company as of the date of grant. 

Stock Option Valuation

The weighted average assumptions the Company used to estimate the fair value of stock options granted during the

years ended December 31, 2018, 2017 and 2016 were as follows:

Risk-free interest rate
Expected term (in years)
Expected volatility
Expected dividend yield

computation of diluted net loss per share since the effect would be to reduce the net loss per share. Therefore, the weighted
average  number  of  common  shares  outstanding  used  to  calculate  both  basic  and  diluted  net  loss  per  share  attributable  to
common  stockholders  is  the  same.    The  following  table  presents  potential  shares  of  common  stock  excluded  from  the
calculation of diluted net loss per share attributable to common stockholders for the years ended December 31, 2018, 2017
and 2016.  All share amounts presented in the table below represent the total number outstanding as of December 31.

Stock Purchase Agreement with Vixen Pharmaceuticals, Inc

Pursuant to the stock purchase agreement with Vixen the Company is obligated to make annual payments of $100

through March 2022, with such amounts being creditable against specified future payments. 

Indemnification Agreements

In  the  ordinary  course  of  business,  the  Company  may  provide  indemnification  of  varying  scope  and  terms  to
vendors, lessors, business partners and other parties with respect to certain matters including, but not limited to, losses arising
out  of  breach  of  such  agreements  or  from  intellectual  property  infringement  claims  made  by  third  parties.  In  addition,  the
Company has entered into indemnification agreements with members of its board of directors that will require the Company,
among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors
or  officers.  The  maximum  potential  amount  of  future  payments  the  Company  could  be  required  to  make  under  these
indemnification agreements is, in many cases, unlimited. To date, the Company has not incurred any material costs as a result
of such indemnifications. The Company does not believe that the outcome of any claims under indemnification arrangements
will have a material effect on its financial position, results of operations or cash flows, and it has not accrued any liabilities
related to such obligations in its consolidated financial statements as of December 31, 2018 or 2017.

13. Income Taxes

The Tax Cuts and Jobs Act of 2017 (the "TCJA") was enacted on December 22, 2017 and became effective January
1,  2018.  The  TCJA  made  significant  changes  to  U.S.  tax  law,  including  lowering  U.S.  corporate  income  tax  rates,
implementing  a  territorial  tax  system,  imposing  a  one-time  transition  tax  on  deemed  repatriated  earnings  of  foreign
subsidiaries and modifying the taxation of other income and expense items.

The TCJA reduced the U.S. corporate income tax rate from 35% to 21%, effective January 1, 2018. Deferred tax
assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those
temporary differences are expected to reverse. As a result of the reduction in the U.S. corporate income tax rate from 35% to
21%  under  the  TCJA,  the  Company  revalued  its  deferred  tax  liabilities,  net  as  of  December  31,  2017.    The  impact  of
revaluation of the deferred tax liabilities, net was $18,507 of income tax expense, which was more than offset by a reduction
in the valuation allowance of $20,344 resulting in a net impact of a $1,837 tax benefit.  The net tax benefit recorded was
primarily the result of tax law changes which impacted the deferred tax liability the Company recorded for IPR&D related to
the acquisition of Confluence.  Under GAAP, IPR&D is an indefinite lived intangible that is capitalized on the balance sheet,
but which does not have a cost basis under U.S. tax law. 

The  TCJA  provided  for  a  one-time  transition  tax  on  the  deemed  repatriation  of  post-1986  undistributed  foreign
subsidiary earnings and profits. The Company did not have consolidated accumulated earnings and profits attributable to its
foreign subsidiary; accordingly, the Company did not record any income tax expense related to the transition tax. 

Due  to  the  timing  of  the  enactment  of  the  TCJA,  the  Staff  of  the  SEC  issued  SAB  118  which  provided  a
measurement period to report the impact of the TCJA.  During the measurement period, provisional amounts for the effects
of  the  law  were  able  to  be  recorded  to  the  extent  a  reasonable  estimate  can  be  made.    To  the  extent  that  all  information
necessary  is  not  available,  prepared  or  analyzed,  companies  were  able  to  recognize  provisional  estimated  amounts  for  a
period  of  up  to  one  year  following  enactment  of  the  TCJA.    The  Company  completed  its  analysis  during  the  year  ended
December 31, 2018, and made no adjustments as a result of TCJA under SAB 118. 

During the years ended December 31, 2018, 2017 and 2016, the Company did not record an income tax benefit for

net operating losses incurred in each year due to the uncertainty of realizing a benefit from those items.

Loss before income taxes is allocated as follows:

As  of  December  31,  2018,  the  Company  had  federal  and  state  net  operating  loss  (“NOL”)  carryforwards  of
$199,507  and  $212,430,  respectively,  which  begin  to  expire  in  2032.   As  of  December  31,  2018,  the  Company  also  had
federal research and development tax credit carryforwards of $4,944 which begin to expire in 2032, and state research and
development  tax  credit  carryforwards  of  $118  which  begin  to  expire  in  2022.  The  Company  also  has  $1,513  of  loss  carry
forwards in the United Kingdom which can be carried forward indefinitely. Utilization of the net operating loss carryforwards
and research and development tax credit carryforwards in the United States may be subject to a substantial annual limitation
under Section 382 of the Internal Revenue Code of 1986 due to ownership changes that may have occurred previously or that
could occur in the future. These ownership changes may limit the amount of carryforwards that can be utilized annually to
offset future taxable income. In general, an ownership change, as defined by Section 382, results from transactions increasing
the  ownership  of  certain  stockholders  or  public  groups  in  the  stock  of  a  corporation  by  more  than  50%  over  a  three-year
period.  The  Company  has  completed  an  analysis  under  Section  382  for  NOLs  generated  from  July  13,  2012  through
December 31, 2016. Although the Company has experienced Section 382 ownership changes since 2012, the Company has
concluded that it should have sufficient ability to utilize NOLs accumulated during the periods tested. The Company has not
yet determined if a Section 382 ownership change has occurred during the years ended December 31, 2017 or 2018, or for
Confluence prior to the acquisition. In addition, the Company may experience ownership changes in the future as a result of
subsequent shifts in its stock ownership, some of which may be outside of the Company’s control. 

The Company has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax
assets.  The Company considered its history of cumulative net losses incurred since inception, its lack of substantial revenue
generated to date, and its forecasted future operating losses and concluded that it is more likely than not that the Company
will not realize the benefits of its deferred tax assets.  Accordingly, a full valuation allowance has been established against the
deferred tax assets as of December 31, 2018 and 2017.  The Company evaluates positive and negative evidence of its’ ability
to realize deferred tax assets at each reporting period.

During  the  year  ended  December  31,  2015,  the  Company  recorded  unrecognized  tax  benefits  in  the  amount  of
$4,400 related to start-up costs that were previously deducted beginning in the initial return filing period ended December 31,
2012.  During the year ended December 31, 2016, the Company filed a method of accounting change with the IRS related to
the  start-up  costs,  and  reversed  the  related  unrecognized  tax  position.    During  the  year  ended  December  31,  2017,  the
Company recorded uncertain tax benefits related to tax positions from the acquired Confluence business, which were settled
during the year ended December 31, 2018.  The following table summarizes the changes in the Company’s unrecognized tax

The total amount of unrecognized tax benefits that, if recognized, would impact the Company’s effective tax rate
were  $0  and  $36  as  of  December  31,  2018  and  2017,  respectively.  The  Company  accrues  interest  and  penalties  related  to
unrecognized  tax  benefits  in  income  tax  expense  (benefit)  in  the  consolidated  statement  of  operations  and  comprehensive
loss.  During each of the years ended December 31, 2018, 2017 and 2016, the Company recognized expense (benefit) of $0,
$3 and $0, respectively, related to interest and penalties.

The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal
course  of  business,  the  Company  is  subject  to  examination  by  federal  and  state  jurisdictions,  where  applicable.  There  are
currently  no  pending  income  tax  examinations.  The  Company’s  tax  years  are  still  open  under  statute  from  2012  to  the
present.  All open years may be examined to the extent that tax credit or net operating loss carryforwards are used in future
periods.  The Company’s policy is to record interest and penalties related to income taxes as part of its income tax provision.

Assignment Agreement with Estate of Mickey Miller and Finder’s Services Agreement with KPT Consulting,

LLC

In August 2012, the Company entered into an assignment agreement with the Estate of Mickey Miller (the “Miller
Estate”)  under  which  the  Company  acquired  some  of  the  intellectual  property  rights  covering  ESKATA  and  A-101  45%
Topical  Solution.  In  connection  with  obtaining  the  assignment  of  the  intellectual  property  from  the  Miller  Estate,  the
Company  also  entered  into  a  separate  finder’s  services  agreement  with  KPT  Consulting,  LLC.    Under  the  terms  of  the
finder’s services agreement, the Company made one-time milestone payments of $300 in the year ended December 31, 2016
upon the dosing of the first human subject with ESKATA in the Company’s Phase 3 clinical trial, $1,000 in the year ended
December 31, 2017 upon the achievement of a specified regulatory milestone and $1,500 in the year ended December 31,
2018 upon the achievement of a specified commercial milestone.  The payments were recorded as general and administrative
expenses in the Company’s consolidated statement of operations.  

Under the finder’s services agreement the Company is obligated to make an additional milestone payment of $3,000
upon  the  achievement  of  a  specified  commercial  milestone.    Under  each  of  the  assignment  agreement  and  the  finder’s
services agreement, the Company is obligated to pay royalties on sales of ESKATA and any related products, at low single-
digit percentages of net sales, subject to reduction in specified circumstances.  The Company incurred an aggregate expense
of $112 and $0 related to royalty payments under these agreements during the years ended December 31, 2018 and 2017,
respectively.    Both  agreements  will  terminate  upon  the  expiration  of  the  last  pending,  viable  patent  claim  of  the  patents
acquired under the assignment agreement, but no sooner than 15 years from the effective date of the agreements.

License Agreement with Rigel Pharmaceuticals, Inc.

In August 2015, the Company entered into an exclusive, worldwide license and collaboration agreement with Rigel
Pharmaceuticals, Inc. (“Rigel”) for the development and commercialization of products containing specified JAK inhibitors
developed  by  Rigel.    Under  this  agreement,  the  Company  intends  to  develop  these  JAK  inhibitors  for  the  treatment  of
alopecia  areata  and  other  dermatological  conditions.    During  the  year  ended  December  31,  2015,  the  Company  made  an
upfront non-refundable payment of $8,000 to Rigel.  In addition, the Company has agreed to make aggregate payments of up
to  $80,000  upon  the  achievement  of  specified  pre‑commercialization  milestones,  such  as  clinical  trials  and  regulatory
approvals. Further, the Company has agreed to pay up to an additional $10,000 to Rigel upon the achievement of a second set
of development milestones. With respect to any products the Company commercializes under the agreement, the Company
will pay Rigel quarterly tiered royalties on its annual net sales of each product at a high single‑digit percentage of annual net
sales, subject to specified reductions, until the date that all of the patent rights for that product have expired, as determined on
a country‑by‑country and product‑by‑product basis or, in specified countries under specified circumstances, ten years from
the first commercial sale of such product.

The agreement terminates on the date of expiration of all royalty obligations unless earlier terminated by either party
for a material breach. The Company may also terminate the agreement without cause at any time upon advance written notice
to Rigel. Rigel, after consultation with the Company, will be responsible for maintaining and prosecuting the patent rights,
and the Company will have final decision making authority regarding such patent rights for a product in the United States
and  the  European  Union.  To  the  extent  that  the  Company  and  Rigel  jointly  develop  intellectual  property,  the  parties  will
confer and decide which party will be responsible for filing, prosecuting and maintaining those patent rights. The agreement
also establishes a joint steering committee composed of an equal number of representatives for each party which will monitor
progress in the development of products.

The  Company  accounted  for  the  transaction  as  an  asset  acquisition  as  the  licensing  arrangement  did  not  meet  the
definition  of  a  business  pursuant  to  the  guidance  prescribed  in  ASC  Topic  805,  Business  Combinations.  Accordingly,  the
Company  recorded  the  $8,000  upfront  payment  as  research  and  development  expense  in  the  year  ended  December  31,
2015.    The  Company  will  record  as  expense  any  contingent  milestone  payments  or  royalties  in  the  period  in  which  such
liabilities  are  incurred.  The  Company  concluded  that  licensing  arrangement  with  Rigel  did  not  meet  the  definition  of  a
business because the transaction principally resulted in its acquisition of intellectual property.  As part of the transaction, the
Company did not acquire any employees or tangible assets, or any processes, protocols or operating systems. In addition, at
the time of the acquisition, there were no activities being conducted related to the licensed patents. The

129

 
 
 
 
 
 
 
 
Table of Contents

Company  expensed  the  cost  of  the  acquired  intellectual  property  as  of  the  acquisition  date  on  the  basis  that  the  cost  of
intellectual property that is purchased for use in research and development activities, and that has no alternative future uses,
is expensed when acquired.

Stock Purchase Agreement with Vixen Pharmaceuticals, Inc. and License Agreement with Columbia
University

In March 2016, the Company entered into a stock purchase agreement (the “Vixen Agreement”) with Vixen, JAK1,
LLC,  JAK2,  LLC  and  JAK3,  LLC  (together,  the  “Selling  Stockholders”)  and  Shareholder  Representative  Services  LLC,
solely  in  its  capacity  as  the  representative  of  the  Selling  Stockholders.  Pursuant  to  the  Vixen  Agreement,  the  Company
acquired all shares of Vixen’s capital stock from the Selling Stockholders. Following the acquisition of Vixen, Vixen became
a wholly-owned subsidiary of the Company. Pursuant to the Vixen Agreement, the Company paid $600 upfront and issued an
aggregate of 159,420 shares of the Company’s common stock to the Selling Stockholders. The Company is obligated to make
annual  payments  of  $100  each  year  through  March  2022,  with  such  amounts  being  creditable  against  specified  future
payments that may be paid under the Vixen Agreement.

The  Company  is  obligated  to  make  aggregate  payments  of  up  to  $18,000  to  the  Selling  Stockholders  upon  the
achievement of specified pre-commercialization milestones for three products in the United States, the European Union and
Japan, and aggregate payments of up to $22,500 upon the achievement of specified commercial milestones. With respect to
any commercialized products covered by the Vixen Agreement, the Company is obligated to pay low single-digit royalties on
net sales, subject to specified reductions, limitations and other adjustments, until the date that all of the patent rights for that
product have expired, as determined on a country-by-country and product-by-product basis or, in specified circumstances, ten
years from the first commercial sale of such product. If the Company sublicenses any of Vixen’s patent rights and know-how
acquired  pursuant  to  the  Vixen  Agreement,  the  Company  will  be  obligated  to  pay  a  portion  of  any  consideration  the
Company receives from such sublicenses in specified circumstances.

As a result of the transaction with Vixen, the Company became party to the Exclusive License Agreement, by and
between Vixen and the Trustees of Columbia University in the City of New York (“Columbia”), dated as of December 31,
2015 (as amended, the “License Agreement”). Under the License Agreement, the Company is obligated to pay Columbia an
annual license fee of $10, subject to specified adjustments for patent expenses incurred by Columbia and creditable against
any royalties that may be paid under the License Agreement. The Company is also obligated to pay up to an aggregate of
$11,600 upon the achievement of specified commercial milestones, including specified levels of net sales of products covered
by  Columbia  patent  rights  and/or  know-how,  and  royalties  at  a  sub-single-digit  percentage  of  annual  net  sales  of  products
covered by Columbia patent rights and/or know-how, subject to specified adjustments. If the Company sublicenses any of
Columbia’s patent rights and know-how acquired pursuant to the License Agreement, it will be obligated to pay Columbia a
portion  of  any  consideration  received  from  such  sublicenses  in  specified  circumstances.  The  royalties,  as  determined  on  a
country-by-country and product-by-product basis, are payable until the date that all of the patent rights for that product have
expired, the expiration of any market exclusivity period granted by a regulatory body or, in specified circumstances, ten years
from the first commercial sale of such product. The License Agreement terminates on the date of expiration of all royalty
obligations thereunder unless earlier terminated by either party for a material breach, subject to a specified cure period. The
Company may also terminate the License Agreement without cause at any time upon advance written notice to Columbia.

The Company accounted for the transaction with Vixen as an asset acquisition as the arrangement did not meet the
definition  of  a  business  pursuant  to  the  guidance  prescribed  in  ASC  Topic  805,  Business  Combinations.  The  Company
concluded the transaction with Vixen did not meet the definition of a business because the transaction principally resulted in
the  acquisition  of  the  License  Agreement.  The  Company  did  not  acquire  tangible  assets,  processes,  protocols  or  operating
systems. In addition, at the time of the transaction, there were no activities being conducted related to the licensed patents.
The Company expensed the acquired intellectual property as of the acquisition date on the basis that the cost of intellectual
property purchased for use in research and development activities, and that has no alternative future uses, is expensed when
acquired.  Accordingly, the Company recorded the $600 upfront payment, the fair value of the shares of common stock issued
of $2,355, and the present value of the six non-contingent annual payments as research and development expense in the year
ended December 31, 2016. Additionally, the Company will record as expense any contingent milestone payments or royalties
in the period in which such liabilities are incurred.

16. Retirement Savings Plan

The Company has a defined contribution savings plan under Section 401(k) of the Internal Revenue Code. This plan
covers  substantially  all  employees  who  meet  minimum  age  and  service  requirements  and  allows  participants  to  defer  a
portion of their annual compensation on a pre-tax basis. Company contributions to the plan may be made at the discretion of
the Company’s board of directors. The Company has elected to match 100% of employee contributions to the 401(k) Plan up
to 4% of the employee’s earnings, subject to certain limitations.  Company contributions under the 401(k) Plan were $662,
$270, and $176 for the years ended December 31, 2018, 2017 and 2016, respectively. 

17. Segment Information

The  Company  has  two  reportable  segments,  dermatology  therapeutics  and  contract  research.    The  dermatology
therapeutics segment is focused on identifying, developing and commercializing innovative therapies to address significant
unmet needs for dermatological and immuno-inflammatory diseases.  The Company currently markets and sells two drugs,
ESKATA and RHOFADE.  ESKATA is a proprietary formulation of high-concentration hydrogen peroxide topical solution
that the Company is commercializing as an office-based prescription treatment for raised SKs, a common non-malignant skin
tumor.  RHOFADE is approved for the topical treatment of persistent facial erythema, or redness, associated with rosacea in
adults.   The  Company  sells  ESKATA  and  RHOFADE  to  a  limited  number  of  wholesalers  in  the  U.S.    These  wholesalers
subsequently resell the Company’s products to pharmacies and health care providers.  The contract research segment earns
revenue  from  the  provision  of  laboratory  services  to  clients  through  Confluence,  the  Company’s  wholly-owned
subsidiary.  Contract research revenue is generally evidenced by contracts with clients which are on an agreed upon fixed-
price,  fee-for-service  basis.    Corporate  and  other  includes  general  and  administrative  expenses  as  well  as  eliminations  of
intercompany transactions.  The Company does not report balance sheet information by segment since it is not reviewed by
the chief operating decision maker, and all of the Company’s tangible assets are held in the United States. 

The  Company’s  results  of  operations  by  segment  for  the  years  ended  December  31,  2018,  2017  and  2016  are

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

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision of and with the participation of our management, including our chief executive officer, who is
our  principal  executive  officer,  and  our  chief  financial  officer,  who  is  our  principal  financial  officer,  we  conducted  an
evaluation  of  the  effectiveness  of  our  disclosure  controls  and  procedures  as  of  December  31,  2018,  the  end  of  the  period
covered by this Annual Report. The term “disclosure controls and procedures,” as set forth in Rules 13a-15(e) and 15d-15(e)
under  the  Securities  Exchange  Act  of  1934,  as  amended,  or  the  Exchange  Act,  means  controls  and  other  procedures  of  a
company that are designed to provide reasonable assurance that information required to be disclosed by a company in the
reports  that  it  files  or  submits  under  the  Exchange  Act  is  recorded,  processed,  summarized  and  reported,  within  the  time
periods  specified  in  the  rules  and  forms  promulgated  by  the  SEC.  Disclosure  controls  and  procedures  include,  without
limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports
that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including
its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.
Management  recognizes  that  any  controls  and  procedures,  no  matter  how  well  designed  and  operated,  can  provide  only
reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-
benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as
of December 31, 2018, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure
controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There  was  no  change  in  our  internal  control  over  financial  reporting  identified  in  connection  with  the  evaluation
required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended December 31, 2018
that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting and Attestation Report of the Registered Public
Accounting Firm

Our  management  is  responsible  for  establishing  and  maintaining  an  adequate  system  of  internal  control  over
financial reporting, as defined in Rule 13a-15(f) of the Exchange Act. Management conducted an assessment of our internal
control over financial reporting based on the framework established in 2013 by the Committee of Sponsoring Organizations
of the Treadway Commission in Internal Control—Integrated Framework.  Based on the assessment, management concluded
that, as of December 31, 2018, our internal control over financial reporting was effective.

This Annual Report does not include an attestation report of our registered public accounting firm regarding internal
control over financial reporting as required by Section 404(b) of the Sarbanes-Oxley Act of 2002. Because we qualify as an
emerging  growth  company  under  the  JOBS  Act,  management's  report  was  not  subject  to  attestation  by  our  independent
registered public accounting firm.

OPTION AGREEMENT

 
 
 
 
ACLARIS  THERAPEUTICS, INC.
2015 EQUITY  INCENTIVE  PLAN

OPTION  AGREEMENT
(INCENTIVE  STOCK  OPTION OR  NONSTATUTORY  STOCK  OPTION)

Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Option Agreement, Aclaris Therapeutics, Inc.
(the “Company”)  has  granted  you  an  option  under  its  2015  Equity  Incentive  Plan  (the  “Plan”)  to  purchase  the  number  of
shares  of  the  Company’s  Common  Stock  indicated  in  your  Grant  Notice  at  the  exercise  price  indicated  in  your  Grant
Notice.  The option is granted to you effective as of the date of grant set forth in the Grant Notice (the “Date of Grant”).  If
there is any conflict between the terms in this Option Agreement and the Plan, the terms of the Plan will control. Capitalized
terms  not  explicitly  defined  in  this  Option  Agreement  or  in  the  Grant  Notice  but  defined  in  the  Plan  will  have  the  same
definitions as in the Plan.

The details of your option, in addition to those set forth in the Grant Notice and the Plan, are as follows:

1.                  VESTING.    Subject  to  the  provisions  contained  herein,  your  option  will  vest  as  provided  in  your  Grant

Notice.  Vesting will cease upon the termination of your Continuous Service.

2.         NUMBER OF SHARES AND EXERCISE PRICE.  The number of shares of Common Stock subject to

your option and your exercise price per share in your Grant Notice will be adjusted for Capitalization Adjustments.

3.         EXERCISE RESTRICTION FOR NON-EXEMPT EMPLOYEES.  If you are an Employee eligible for
overtime compensation under the Fair Labor Standards Act of 1938, as amended (that is, a “Non-Exempt Employee”),  and
except as otherwise provided in the Plan, you may not exercise your option until you have completed at least six (6) months of
Continuous  Service  measured  from  the  Date  of  Grant,  even  if  you  have  already  been  an  employee  for  more  than  six  (6)
months.  Consistent  with  the  provisions  of  the  Worker  Economic  Opportunity  Act,  you  may  exercise  your  option  as  to  any
vested portion prior to such six (6) month anniversary in the case of (i) your death or disability, (ii) a Corporate Transaction in
which your option is not assumed, continued or substituted, (iii) a Change in Control or (iv) your termination of Continuous
Service on your “retirement” (as defined in the Company’s benefit plans).

4.         METHOD OF PAYMENT.  You must pay the full amount of the exercise price for the shares you wish to
exercise.  You may pay the exercise price in cash or by check, bank draft or money order payable to the Company or in any
other manner permitted by your Grant Notice, which may include one or more of the following:

(a)        Pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board
that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of
irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds.  This manner of payment
is also known as a “broker-assisted exercise”,  “same day sale”, or “sell to cover”.

(b)              By  delivery  to  the  Company  (either  by  actual  delivery  or  attestation)  of  already-owned  shares  of
Common Stock that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at
Fair Market Value on the date of exercise.  “Delivery” for these purposes, in the sole discretion of the Company at the time
you exercise your option, will include delivery to the

1

 
 
Company of your attestation of ownership of such shares of Common Stock in a form approved by the Company.  You may
not exercise your option by delivery to the Company of Common Stock if doing so would violate the provisions of any law,
regulation or agreement restricting the redemption of the Company’s stock.

(c)        If this option is a Nonstatutory Stock Option, subject to the consent of the Company at the time of
exercise, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock
issued upon exercise of your option by the largest whole number of shares with a Fair Market Value that does not exceed the
aggregate  exercise  price.    You  must  pay  any  remaining  balance  of  the  aggregate  exercise  price  not  satisfied  by  the  “net
exercise”  in  cash  or  other  permitted  form  of  payment.    Shares  of  Common  Stock  will  no  longer  be  outstanding  under  your
option and will not be exercisable thereafter if those shares (i) are used to pay the exercise price pursuant to the “net exercise,”
(ii) are delivered to you as a result of such exercise, and (iii) are withheld to satisfy your tax withholding obligations.

5.         WHOLE  SHARES.  You may exercise your option only for whole shares of Common Stock.

6.         SECURITIES  LAW  COMPLIANCE.  In no event may you exercise your option unless the shares of Common
Stock issuable upon exercise are then registered under the Securities Act or, if not registered, the Company has determined that
your exercise and the issuance of the shares would be exempt from the registration requirements of the Securities Act.  The
exercise of your option also must comply with all other applicable laws and regulations governing your option, and you may
not exercise your option if the Company determines that such exercise would not be in material compliance with such laws
and  regulations  (including  any  restrictions  on  exercise  required  for  compliance  with  Treas.  Reg.  1.401(k)-1(d)(3),  if
applicable).

7.         TERM.  You may not exercise your option before the Date of Grant or after the expiration of the option’s
term.  The term of your option expires, subject to the provisions of Section 5(h) of the Plan and the Grant Notice, upon the
earliest of the following:

(a)        immediately upon the date on which the event giving rise to your termination of Continuous Service

for Cause occurs (or, if required by law, the date of termination of Continuous Service for Cause);

(b)       three (3) months after the termination of your Continuous Service for any reason other than Cause,
your Disability or your death (except as otherwise provided in Section 7(d) below); provided, however, that if during any part
of  such  three  (3)  month  period  your  option  is  not  exercisable  solely  because  of  the  condition  set  forth  in  the  section  above
relating to “Securities Law Compliance,” your option will not expire until the earlier of the Expiration Date or until it has been
exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; provided further, if
during any part of such three (3) month period, the sale of any Common Stock received upon exercise of your option would
violate the Company’s insider trading policy, then your option will not expire until the earlier of the Expiration Date or until it
has  been  exercisable  for  an  aggregate  period  of  three  (3)  months  after  the  termination  of  your  Continuous  Service  during
which the sale of the Common Stock received upon exercise of your option would not be in violation of the Company’s insider
trading policy.  Notwithstanding the foregoing, if (i) you are a Non-Exempt Employee, (ii) your Continuous Service terminates
within  six  (6)  months  after  the  Date  of  Grant,  and  (iii)  you  have  vested  in  a  portion  of  your  option  at  the  time  of  your
termination of Continuous Service, your option will not expire until the earlier of (x) the later of (A) the date that is seven (7)
months after the Date of Grant, and (B) the date that is three (3) months after the termination of your Continuous Service, and
(y) the Expiration Date;

2

 
(c)        twelve (12) months after the termination of your Continuous Service due to your Disability (except as

otherwise provided in Section 7(d)) below;

(d)       eighteen (18) months after your death if you die either during your Continuous Service or within three

(3) months after your Continuous Service terminates for any reason other than Cause;

(e)        in certain circumstances upon the effective date of a Transaction as set forth in the Plan;

(f)        the Expiration Date indicated in your Grant Notice; or

(g)        the day before the tenth (10th) anniversary of the Date of Grant.

If your option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an
Incentive Stock Option, the Code requires that at all times beginning on the Date of Grant and ending on the day three (3)
months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in the event
of your death or Disability.  The Company has provided for extended exercisability of your option under certain circumstances
for your benefit but cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you continue
to  provide  services  to  the  Company  or  an  Affiliate  as  a  Consultant  or  Director  after  your  employment  terminates  or  if  you
otherwise exercise your option more than three (3) months after the date your employment with the Company or an Affiliate
terminates.

8.         EXERCISE.

(a)                You  may  exercise  the  vested  portion  of  your  option  during  its  term  by  (i)  delivering  a  Notice  of
Exercise  (in  a  form  designated  by  the  Company)  or  completing  such  other  documents  and/or  procedures  designated  by  the
Company  for  exercise  and  (ii)  paying  the  exercise  price  and  any  applicable  withholding  taxes  to  the  Company’s  Secretary,
stock plan administrator, or such other person as the Company may designate, together with such additional documents as the
Company may then require.

(b)       By exercising your option you agree that, as a condition to any exercise of your option, the Company
may  require  you  to  enter  into  an  arrangement  providing  for  the  payment  by  you  to  the  Company  of  any  tax  withholding
obligation of the Company arising by reason of (i) the exercise of your option, (ii) the lapse of any substantial risk of forfeiture
to which the shares of Common Stock are subject at the time of exercise, or (iii) the disposition of shares of Common Stock
acquired upon such exercise.

(c)        If your option is an Incentive Stock Option, by exercising your option you agree that you will notify
the Company in writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Stock
issued upon exercise of your option that occurs within two (2) years after the Date of Grant or within one (1) year after such
shares of Common Stock are transferred upon exercise of your option.

9.         TRANSFERABILITY.  Except as otherwise provided in this Section 9, your option is not transferable, except by

will or by the laws of descent and distribution, and is exercisable during your life only by you.

(a)        Certain Trusts.  Upon receiving written permission from the Board or its duly authorized designee,

you may transfer your option to a trust if you are considered to be the sole beneficial

3

 
owner (determined under Section 671 of the Code and applicable state law) while the option is held in the trust.  You and the
trustee must enter into transfer and other agreements required by the Company.

(b)              Domestic  Relations  Orders.    Upon  receiving  written  permission  from  the  Board  or  its  duly
authorized designee, and provided that you and the designated transferee enter into transfer and other agreements required by
the  Company,  you  may  transfer  your  option  pursuant  to  the  terms  of  a  domestic  relations  order,  official  marital  settlement
agreement  or  other  divorce  or  separation  instrument  as  permitted  by  Treasury  Regulation  1.421-1(b)(2)  that  contains  the
information  required  by  the  Company  to  effectuate  the  transfer.   You  are  encouraged  to  discuss  the  proposed  terms  of  any
division of this option with the Company prior to finalizing the domestic relations order or marital settlement agreement to
help ensure the required information is contained within the domestic relations order or marital settlement agreement.  If this
option is an Incentive Stock Option, this option may be deemed to be a Nonstatutory Stock Option as a result of such transfer.

(c)        Beneficiary Designation.  Upon receiving written permission from the Board or its duly authorized
designee,  you  may,  by  delivering  written  notice  to  the  Company,  in  a  form  approved  by  the  Company  and  any  broker
designated by the Company to handle option exercises, designate a third party who, on your death, will thereafter be entitled to
exercise this option and receive the Common Stock or other consideration resulting from such exercise.  In the absence of such
a designation, your executor or administrator of your estate will be entitled to exercise this option and receive, on behalf of
your estate, the Common Stock or other consideration resulting from such exercise.

10.       OPTION NOT A  SERVICE  CONTRACT.  Your option is not an employment or service contract, and nothing in
your  option  will  be  deemed  to  create  in  any  way  whatsoever  any  obligation  on  your  part  to  continue  in  the  employ  of  the
Company or an Affiliate, or of the Company or an Affiliate to continue your employment.  In addition, nothing in your option
will obligate the Company or an Affiliate, their respective stockholders, boards of directors, officers or employees to continue
any relationship that you might have as a Director or Consultant for the Company or an Affiliate.

11.       WITHHOLDING  OBLIGATIONS.

(a)        At the time you exercise your option, in whole or in part, and at any time thereafter as requested by
the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to
make adequate provision for (including by means of a “same day sale” pursuant to a program developed under Regulation T as
promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal,
state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the
exercise of your option.

(b)       If this option is a Nonstatutory Stock Option, then upon your request and subject to approval by the
Company, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested
shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common
Stock  having  a  Fair  Market  Value,  determined  by  the  Company  as  of  the  date  of  exercise,  not  in  excess  of  the  minimum
amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of your option
as a liability for financial accounting purposes).  If the date of determination of any tax withholding obligation is deferred to a
date later than the date of exercise of your option, share withholding pursuant to the preceding sentence shall not be permitted
unless you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of
Common Stock acquired upon such exercise with respect to which such determination is otherwise deferred, to accelerate the
determination of such tax withholding obligation to the date of exercise of your option.  Notwithstanding the filing of such
election,

4

 
shares  of  Common  Stock  shall  be  withheld  solely  from  fully  vested  shares  of  Common  Stock  determined  as  of  the  date  of
exercise of your option that are otherwise issuable to you upon such exercise.  Any adverse consequences to you arising in
connection with such share withholding procedure shall be your sole responsibility.

(c)        You may not exercise your option unless the tax withholding obligations of the Company and/or any
Affiliate  are  satisfied.   Accordingly,  you  may  not  be  able  to  exercise  your  option  when  desired  even  though  your  option  is
vested, and the Company will have no obligation to issue a certificate for such shares of Common Stock or release such shares
of Common Stock from any escrow provided for herein, if applicable, unless such obligations are satisfied.

12.       TAX  CONSEQUENCES. You hereby agree that the Company does not have a duty to design or administer the
Plan or its other compensation programs in a manner that minimizes your tax liabilities. You will not make any claim against
the  Company,  or  any  of  its  Officers,  Directors,  Employees  or  Affiliates  related  to  tax  liabilities  arising  from  your  option  or
your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the Code only if the
exercise  price  per  share  specified  in  the  Grant  Notice  is  at  least  equal  to  the  “fair  market  value”  per  share  of  the  Common
Stock on the Date of Grant and there is no other impermissible deferral of compensation associated with the option.

13.              NOTICES.    Any  notices  provided  for  in  your  option  or  the  Plan  will  be  given  in  writing  (including
electronically) and will be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company
to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided
to the Company.  The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan
and this option by electronic means or to request your consent to participate in the Plan by electronic means.  By accepting this
option,  you  consent  to  receive  such  documents  by  electronic  delivery  and  to  participate  in  the  Plan  through  an  on-line  or
electronic system established and maintained by the Company or another third party designated by the Company.

14.       GOVERNING  PLAN  DOCUMENT.  Your option is subject to all the provisions of the Plan, the provisions of
which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations,
which may from time to time be promulgated and adopted pursuant to the Plan.  If there is any conflict between the provisions
of your option and those of the Plan, the provisions of the Plan will control.  In addition, your option (and any compensation
paid or shares issued under your option) is subject to recoupment in accordance with The Dodd–Frank Wall Street Reform and
Consumer  Protection  Act  and  any  implementing  regulations  thereunder,  any  clawback  policy  adopted  by  the  Company  and
any compensation recovery policy otherwise required by applicable law.

15.       OTHER  DOCUMENTS.  You hereby acknowledge receipt of and the right to receive a document providing the
information  required  by  Rule  428(b)(1)  promulgated  under  the  Securities  Act,  which  includes  the  Plan  prospectus.    In
addition, you acknowledge receipt of the Company’s policy permitting certain individuals to sell shares only during certain
“window” periods and the Company’s insider trading policy, in effect from time to time.

16.              EFFECT  ON  OTHER    EMPLOYEE    BENEFIT    PLANS.    The  value  of  this  option  will  not  be  included  as
compensation, earnings, salaries, or other similar terms used when calculating your benefits under any employee benefit plan
sponsored  by  the  Company  or  any  Affiliate,  except  as  such  plan  otherwise  expressly  provides.  The  Company  expressly
reserves its rights to amend, modify, or terminate any of the Company’s or any Affiliate’s employee benefit plans.

5

 
17.       VOTING  RIGHTS.  You will not have voting or any other rights as a stockholder of the Company with respect
to the shares to be issued pursuant to this option until such shares are issued to you.  Upon such issuance, you will obtain full
voting and other rights as a stockholder of the Company.  Nothing contained in this option, and no action taken pursuant to its
provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or
any other person.

18.              SEVERABILITY.    If  all  or  any  part  of  this  Option  Agreement  or  the  Plan  is  declared  by  any  court  or
governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Option
Agreement  or  the  Plan  not  declared  to  be  unlawful  or  invalid.   Any  Section  of  this  Option  Agreement  (or  part  of  such  a
Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of
such Section or part of a Section to the fullest extent possible while remaining lawful and valid.

19.       MISCELLANEOUS.

(a)        The rights and obligations of the Company under your option will be transferable to any one or more
persons  or  entities,  and  all  covenants  and  agreements  hereunder  will  inure  to  the  benefit  of,  and  be  enforceable  by  the
Company’s successors and assigns.

(b)       You agree upon request to execute any further documents or instruments necessary or desirable in the

sole determination of the Company to carry out the purposes or intent of your option.

(c)                You  acknowledge  and  agree  that  you  have  reviewed  your  option  in  its  entirety,  have  had  an
opportunity to obtain the advice of counsel prior to executing and accepting your option, and fully understand all provisions of
your option.

(d)              This  Option  Agreement  will  be  subject  to  all  applicable  laws,  rules,  and  regulations,  and  to  such

approvals by any governmental agencies or national securities exchanges as may be required.

(e)        All obligations of the Company under the Plan and this Option Agreement will be binding on any
successor  to  the  Company,  whether  the  existence  of  such  successor  is  the  result  of  a  direct  or  indirect  purchase,  merger,
consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company.

This Option Agreement will be deemed to be signed by you upon the signing by you of the Grant Notice to which it is
attached.

RESTRICTED STOCK UNIT AWARD AGREEMENT

 
 
 
ACLARIS THERAPEUTICS, INC.
RESTRICTED STOCK UNIT AWARD AGREEMENT
(2015 EQUITY INCENTIVE PLAN)

Pursuant  to  the  Restricted  Stock  Unit  Grant  Notice  (the  “Grant  Notice”)  and  this  Restricted  Stock  Unit
Award  Agreement  (the  “Agreement”),  Aclaris  Therapeutics,  Inc.  (the 
  “Company”)  has  awarded  you
(“Participant”)  a  Restricted  Stock  Unit  Award  (the  “Award”)  pursuant  to  Section  6(b)  of  the  Company’s  2015
Equity Incentive Plan (the “Plan”) for the number of Restricted Stock Units/shares indicated in the Grant Notice.
Capitalized terms not explicitly defined in this Agreement or the Grant Notice shall have the same meanings given
to them in the Plan. The terms of your Award, in addition to those set forth in the Grant Notice, are as follows.

1.         GRANT OF THE AWARD. This Award represents the right to be issued on a future date one (1)
share of Common Stock for each Restricted Stock Unit that vests on the applicable vesting date(s) (subject to any
adjustment  under  Section  3  below)  as  indicated  in  the  Grant  Notice.  As  of  the  Date  of  Grant,  the  Company  will
credit  to  a  bookkeeping  account  maintained  by  the  Company  for  your  benefit  (the  “Account”)  the  number  of
Restricted Stock Units/shares of Common Stock subject to the Award. This Award was granted in consideration of
your services to the Company.

2.         VESTING. Subject to the limitations contained herein and in the Grant Notice, your Award will
vest, if at all, in accordance with the vesting schedule provided in the Grant Notice, provided that vesting will cease
upon the termination of your Continuous Service. Upon such termination of your Continuous Service, the Restricted
Stock Units/shares of Common Stock credited to the Account that were not vested on the date of such termination
will  be  forfeited  at  no  cost  to  the  Company  and  you  will  have  no  further  right,  title  or  interest  in  or  to  such
underlying shares of Common Stock.

3.         NUMBER OF SHARES. The number of Restricted Stock Units/shares subject to your Award may
be  adjusted  from  time  to  time  for  Capitalization  Adjustments,  as  provided  in  the  Plan.  Any  additional  Restricted
Stock Units, shares, cash or other property that becomes subject to the Award pursuant to this Section 3, if any, shall
be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability,
and  time  and  manner  of  delivery  as  applicable  to  the  other  Restricted  Stock  Units  and  shares  covered  by  your
Award.  Notwithstanding  the  provisions  of  this  Section  3,  no  fractional  shares  or  rights  for  fractional  shares  of
Common  Stock  shall  be  created  pursuant  to  this  Section  3.  Any  fraction  of  a  share  will  be  rounded  down  to  the
nearest whole share.

4.                  SECURITIES LAW COMPLIANCE.  You  may  not  be  issued  any  Common  Stock  under  your
Award unless the shares of Common Stock underlying the Restricted Stock Units are either (i) then registered under
the Securities Act, or (ii) the Company has determined that such issuance would be exempt from the registration
requirements  of  the  Securities  Act.  Your  Award  must  also  comply  with  other  applicable  laws  and  regulations
governing the Award, and you shall not receive such Common Stock if the Company determines that such receipt
would not be in material compliance with such laws and regulations.

1.

 
 
5.         TRANSFER RESTRICTIONS. Prior to the time that shares of Common Stock have been delivered
to you, you may not transfer, pledge, sell or otherwise dispose of this Award or the shares issuable in respect of your
Award, except as expressly provided in this Section 5. For example, you may not use shares that may be issued in
respect of your Restricted Stock Units as security for a loan. The restrictions on transfer set forth herein will lapse
upon delivery to you of shares in respect of your vested Restricted Stock Units.

(a)         Death. Your Award is transferable by will and by the laws of descent and distribution. At
your death, vesting of your Award will cease and your executor or administrator of your estate shall be entitled to
receive, on behalf of your estate, any Common Stock or other consideration that vested but was not issued before
your death.

(b)         Domestic Relations Orders. Upon receiving written permission from the Board or its duly
authorized designee, and provided that you and the designated transferee enter into transfer and other agreements
required  by  the  Company,  you  may  transfer  your  right  to  receive  the  distribution  of  Common  Stock  or  other
consideration  hereunder,  pursuant  to  a  domestic  relations  order  or  marital  settlement  agreement  that  contains  the
information required by the Company to effectuate the transfer. You are encouraged to discuss the proposed terms
of  any  division  of  this  Award  with  the  Company’s  Chief  Legal  Officer  prior  to  finalizing  the  domestic  relations
order  or  marital  settlement  agreement  to  verify  that  you  may  make  such  transfer,  and  if  so,  to  help  ensure  the
required information is contained within the domestic relations order or marital settlement agreement.

6.         DATE OF ISSUANCE.

(a)         The issuance of shares in respect of the Restricted Stock Units is intended to comply with
Treasury Regulations Section 1.409A-1(b)(4) and will be construed and administered in such a manner. Subject to
the satisfaction of the withholding obligations set forth in this Agreement, in the event one or more Restricted Stock
Units  vests,  the  Company  shall  issue  to  you  one  (1)  share  of  Common  Stock  for  each  Restricted  Stock  Unit  that
vests  on  the  applicable  vesting  date(s)  (subject  to  any  adjustment  under  Section  3  above).  The  issuance  date
determined by this paragraph is referred to as the “Original Issuance Date”.

(b)         If the Original Issuance Date falls on a date that is not a business day, delivery shall instead

occur on the next following business day. In addition, if:

(i)                  the  Original  Issuance  Date  does  not  occur  (1)  during  an  “open  window  period”
applicable  to  you,  as  determined  by  the  Company  in  accordance  with  the  Company’s  then-effective  policy  on
trading in Company securities, or (2) on a date when you are otherwise permitted to sell shares of Common Stock
on an established stock exchange or stock market, and

(ii)       either (1) Withholding Taxes do not apply, or (2) the Company decides, prior to the
Original Issuance Date, (A) not to satisfy the Withholding Taxes by withholding shares of Common Stock from the
shares otherwise due, on the Original Issuance Date, to you under this Award, and (B) not to permit you to pay your
Withholding Taxes in cash,

2.

 
then the shares that would otherwise be issued to you on the Original Issuance Date will not be delivered on
such  Original  Issuance  Date  and  will  instead  be  delivered  on  the  first  business  day  when  you  are  not  prohibited
from  selling  shares  of  the  Company’s  Common  Stock  in  the  open  public  market,  but  in  no  event  later  than
December 31 of the calendar year in which the Original Issuance Date occurs (that is, the last day of your taxable
year  in  which  the  Original  Issuance  Date  occurs),  or,  if  and  only  if  permitted  in  a  manner  that  complies  with
Treasury Regulations Section 1.409A-1(b)(4), no later than the date that is the 15th day of the third calendar month
of  the  applicable  year  following  the  year  in  which  the  shares  of  Common  Stock  under  this  Award  are  no  longer
subject to a “substantial risk of forfeiture” within the meaning of Treasury Regulations Section 1.409A-1(d).

(c)         The form of delivery (e.g., a stock certificate or electronic entry evidencing such shares)

shall be determined by the Company.

7.         DIVIDENDS. You shall receive no benefit or adjustment to your Award with respect to any cash

dividend, stock dividend or other distribution that does not result from a Capitalization Adjustment.

8.                  RESTRICTIVE  LEGENDS.  The  shares  of  Common  Stock  issued  under  your  Award  shall  be

endorsed with appropriate legends as determined by the Company.

9.         EXECUTION OF DOCUMENTS. You hereby acknowledge and agree that the manner selected by
the Company by which you indicate your consent to your Grant Notice is also deemed to be your execution of your
Grant Notice and of this Agreement. You further agree that such manner of indicating consent may be relied upon
as your signature for establishing your execution of any documents to be executed in the future in connection with
your Award.

10.       AWARD NOT A SERVICE CONTRACT.

(a)         Nothing in this Agreement (including, but not limited to, the vesting of your Award or the
issuance of the shares subject to your Award), the Plan or any covenant of good faith and fair dealing that may be
found implicit in this Agreement or the Plan shall: (i) confer upon you any right to continue in the employ of, or
affiliation  with,  the  Company  or  an  Affiliate;  (ii)  constitute  any  promise  or  commitment  by  the  Company  or  an
Affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other
term or condition of employment or affiliation; (iii) confer any right or benefit under this Agreement or the Plan
unless such right or benefit has specifically accrued under the terms of this Agreement or Plan; or (iv) deprive the
Company of the right to terminate you at will and without regard to any future vesting opportunity that you may
have.

(b)         The Company has the right to reorganize, sell, spin-out or otherwise restructure one or more
of its businesses or Affiliates at any time or from time to time, as it deems appropriate (a “reorganization”). Such a
reorganization could result in the termination of your Continuous Service, or the termination of Affiliate status of
your  employer  and  the  loss  of  benefits  available  to  you  under  this  Agreement,  including  but  not  limited  to,  the
termination of the right to continue vesting in the Award. This Agreement, the Plan, the transactions contemplated
hereunder and the vesting schedule set forth herein or any covenant of good faith and fair dealing

3.

 
that  may  be  found  implicit  in  any  of  them  do  not  constitute  an  express  or  implied  promise  of  continued
engagement as an employee or consultant for the term of this Agreement, for any period, or at all, and shall not
interfere in any way with the Company’s right to conduct a reorganization.

11.       WITHHOLDING OBLIGATIONS.

(a)         On  each  vesting  date,  and  on  or  before  the  time  you  receive  a  distribution  of  the  shares
underlying  your  Restricted  Stock  Units,  and  at  any  other  time  as  reasonably  requested  by  the  Company  in
accordance  with  applicable  tax  laws,  you  hereby  authorize  any  required  withholding  from  the  Common  Stock
issuable  to  you  and/or  otherwise  agree  to  make  adequate  provision  in  cash  for  any  sums  required  to  satisfy  the
federal, state, local and foreign tax withholding obligations of the Company or any Affiliate that arise in connection
with your Award (the “Withholding Taxes”).  Additionally, the Company or any Affiliate may, in its sole discretion,
satisfy all or any portion of the Withholding Taxes obligation relating to your Award by any of the following means
or  by  a  combination  of  such  means:  (i)  withholding  from  any  compensation  otherwise  payable  to  you  by  the
Company; (ii) causing you to tender a cash payment; (iii) permitting or requiring you to enter into a “same day sale”
commitment, if applicable, with a broker-dealer that is a member of the Financial Industry Regulatory Authority (a
“FINRA Dealer”) whereby you irrevocably elect to sell a portion of the shares to be delivered in connection with
your Restricted Stock Units to satisfy the Withholding Taxes and whereby the FINRA Dealer irrevocably commits
to forward the proceeds necessary to satisfy the Withholding Taxes directly to the Company and/or its Affiliates; or
(iv) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to you in
connection with the Award with a Fair Market Value (measured as of the date shares of Common Stock are issued to
pursuant to Section 6) equal to the amount of such Withholding Taxes; provided,  however, that the number of such
shares of Common Stock so withheld will not exceed the amount necessary to satisfy the Company’s required tax
withholding  obligations  using  the  minimum  statutory  withholding  rates  for  federal,  state,  local  and  foreign  tax
purposes, including payroll taxes, that are applicable to supplemental taxable income; and provided, further, that to
the  extent  necessary  to  qualify  for  an  exemption  from  application  of  Section  16(b)  of  the  Exchange  Act,  if
applicable,  such  share  withholding  procedure  will  be  subject  to  the  express  prior  approval  of  the  Company’s
Compensation Committee.

(b)         Unless the tax withholding obligations of the Company and/or any Affiliate are satisfied, the

Company shall have no obligation to deliver to you any Common Stock.

(c)         In  the  event  the  Company’s  obligation  to  withhold  arises  prior  to  the  delivery  to  you  of
Common Stock or it is determined after the delivery of Common Stock to you that the amount of the Company’s
withholding obligation was greater than the amount withheld by the Company, you agree to indemnify and hold the
Company harmless from any failure by the Company to withhold the proper amount.

12.              TAX  CONSEQUENCES.  The  Company  has  no  duty  or  obligation  to  minimize  the  tax
consequences to you of this Award and shall not be liable to you for any adverse tax consequences to you arising in
connection with this Award. You are hereby advised to consult with your own personal tax, financial and/or legal

foregoing,  this  Agreement  may  be  amended  solely  by  the  Board  by  a  writing  which  specifically  states  that  it  is

may be made without your written consent. Without limiting the foregoing, the Board reserves the right to change,
by written notice to you, the provisions of this Agreement in any way it may deem necessary or advisable to carry

foregoing, if it is determined that the Award fails to satisfy the requirements of the short-term deferral rule and is
otherwise  deferred  compensation  subject  to  Section  409A,  and  if  you  are  a  “Specified  Employee”  (within  the
meaning set forth in Section 409A(a)(2)(B)(i) of the Code) as of the date of your “separation from service”  (within
the  meaning  of  Treasury  Regulation  Section  1.409A-1(h)  and  without  regard  to  any  alternative  definition
thereunder),  then  the  issuance  of  any  shares  that  would  otherwise  be  made  upon  the  date  of  the  separation  from
service or within the first six (6) months thereafter will not be made on the originally scheduled date(s) and will
instead be issued in a lump sum on the date that is six (6) months and one day after the date of the separation from
service,  with  the  balance  of  the  shares  issued  thereafter  in  accordance  with  the  original  vesting  and  issuance
schedule  set  forth  above,  but  if  and  only  if  such  delay  in  the  issuance  of  the  shares  is  necessary  to  avoid  the
imposition of adverse taxation on you in respect of the shares under Section 409A of the Code. Each installment of
shares that vests is intended to constitute a “separate payment” for purposes of Treasury Regulation Section 1.409A-
2(b)(2).

determined by the Board or the Compensation Committee (or any combination of clause (a) and this clause (b)).  The shares subject to each
such stock option will vest in equal monthly installments for 12 months and the restricted stock units will vest in one installment on the

(a)          Availability.

(i)           Subject to the terms and conditions of this Agreement, the Lenders agree, severally and not jointly, to

successive month thereafter through and including the Payment Date immediately preceding the Amortization Date.  Borrower agrees to
pay, on the Funding Date of the Term Loan, any initial partial monthly interest payment otherwise due for the period between the Funding
Date of the Term Loan and the first Payment Date thereof.  Commencing on the Amortization Date, and continuing on the Payment Date of
each month thereafter, Borrower shall make consecutive equal monthly payments of principal, together with applicable interest, in arrears,
to each Lender, as calculated by Collateral Agent (which calculations shall be deemed correct absent manifest error) based upon: (1) the
amount of such Lender’s Term Loan, (2) the effective rate of interest, as determined in Section 2.3(a), and (3) a repayment schedule equal
to twenty four (24) months.  All unpaid principal and accrued and unpaid interest with respect to the Term Loan is due and payable in full
on the Maturity Date.  The Term Loan may only be prepaid in accordance with Sections 2.2(c) and 2.2(d).

(c)          Mandatory Prepayments.  If the Term Loans are accelerated following the occurrence of an Event of Default,
Borrower shall immediately pay to Lenders, payable to each Lender in accordance with its respective Pro Rata Share, an amount equal to
the sum of: (i) all outstanding principal of the Term Loans plus accrued and unpaid interest thereon through the prepayment date, (ii) the
Final Payment, (iii) the Prepayment Fee, plus (iv) all other Obligations that are due and payable, including Lenders’ Expenses and interest
at the Default Rate with respect to any past due amounts. Notwithstanding (but without duplication with) the foregoing, on the Maturity
Date, if the Final Payment had not previously been paid in full in connection with the prepayment of the Term Loans in full, Borrower shall
pay to Collateral Agent, for payment to each Lender in accordance with its respective Pro Rata Share, the Final Payment in respect of the
Term Loans.

(d)          Permitted Prepayment of Term Loans.

(i)           Borrower shall have the option to prepay all, but not less than all, of the Term Loans advanced by the
Lenders under this Agreement, provided Borrower (i) provides written notice to Collateral Agent of its election to prepay the Term Loans
at least ten (10) days prior to such prepayment, and (ii) pays to the Lenders on the date of such prepayment, payable to each Lender in
accordance with its respective Pro Rata Share, an amount equal to the sum of (A) all outstanding principal of the Term Loans plus accrued
and unpaid interest thereon through the prepayment date, (B) the Final Payment, (C) the Prepayment Fee, plus (D) all other Obligations
that are due and payable, including Lenders’ Expenses and interest at the Default Rate with respect to any past due amounts.

(ii)          Notwithstanding anything herein to the contrary, Borrower shall also have the option to prepay, once in
any given three month period, part of Term Loans advanced by the Lenders under this Agreement, provided Borrower (i) provides written
notice to Collateral Agent of its election to prepay the Term Loans at least ten (10) days prior to such prepayment, (ii) prepays such part of
the  Term  Loans  in  an  amount  not  less  than  Two  Million  Dollars  ($2,000,000.00),  and  (iii)  pays  to  the  Lenders  on  the  date  of  such
prepayment, payable to each Lender in accordance with its respective Pro Rata Share, an amount equal to the sum of (A) the portion of
outstanding  principal  of  such  Term  Loans  plus  all  accrued  and  unpaid  interest  thereon  through  the  prepayment  date,  (B)  the  applicable
Final Payment, and (C) all other Obligations that are then due and payable, including Lenders’ Expenses and interest at the Default Rate
with respect to any past due amounts, and (D) the applicable Prepayment Fee with respect to the portion of such Term Loans being prepaid.
For the purposes of clarity, any partial prepayment shall be applied pro-rata to all outstanding amounts under each Term Loan, and shall be
applied  pro-rata  within  each  Term  Loan  tranche  to  reduce  amortization  payments  under  Section  2.2(b)  on  a  pro-rata  basis.    For  the
avoidance of doubt, Borrower may make one or more partial prepayments prior to the Maturity Date.

2.3          Payment of Interest on the Credit Extensions.

(a)          Interest Rate.  Subject to Section 2.3(b), the principal amount outstanding under the Term Loans shall accrue
interest  at  a  floating  per  annum  rate  equal  to  the  Basic  Rate,  determined  by  Collateral  Agent  from  time  to  time,  which  interest  shall  be
payable monthly in arrears in accordance with Sections 2.2(b) and 2.3(e). Interest shall accrue on each Term Loan commencing on, and
including, the Funding Date of such Term Loan, and

shall accrue interest at a floating per annum rate equal to the rate that is otherwise applicable thereto plus five percentage points (5.00%)
(the “Default Rate”).  Payment or acceptance of the increased interest rate provided in this Section 2.3(b) is not a permitted alternative to
timely  payment  and  shall  not  constitute  a  waiver  of  any  Event  of  Default  or  otherwise  prejudice  or  limit  any  rights  or  remedies  of

(d)          Debit of Accounts.  Collateral Agent and each Lender may debit (or ACH) any deposit accounts, maintained by
Borrower or any of its Subsidiaries, including the Designated Deposit Account, for principal and interest payments or any other amounts
Borrower owes the Lenders under the Loan Documents when due.  Any such debits (or ACH activity) shall not constitute a set‑off.

(e)                    Payments.    Except  as  otherwise  expressly  provided  herein,  all  payments  by  Borrower  under  the  Loan
Documents  shall  be  made  to  the  respective  Lender  to  which  such  payments  are  owed,  at  such  Lender’s  office  in  immediately  available
funds on the date specified herein. Unless otherwise provided, interest is payable monthly on the Payment Date of each month.  Payments
of principal and/or interest received after 2:00 p.m. Eastern time are considered received at the opening of business on the next Business
Day.  When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest,
as applicable, shall continue to accrue until paid. All payments to be made by Borrower hereunder or under any other Loan Document,
including  payments  of  principal  and  interest,  and  all  fees,  expenses,  indemnities  and  reimbursements,  shall  be  made  without  set‑off,
recoupment or counterclaim, in lawful money of the United States and in immediately available funds.

2.4          Secured Promissory Notes.  The Term Loans shall be evidenced by a Secured Promissory Note or Notes in the form
attached  as  Exhibit  D  hereto  (each  a  “Secured  Promissory  Note”),  and  shall  be  repayable  as  set  forth  in  this  Agreement.    Borrower
irrevocably authorizes each Lender to make or cause to be made, on or about the Funding Date of any Term Loan or at the time of receipt
of  any  payment  of  principal  on  such  Lender’s  Secured  Promissory  Note,  an  appropriate  notation  on  such  Lender’s  Secured  Promissory
Note Record reflecting the making of such Term Loan or (as the case may be) the receipt of such payment.  The outstanding amount of
each Term Loan set forth on such Lender’s Secured Promissory Note Record shall be prima facie evidence of the principal amount thereof
owing  and  unpaid  to  such  Lender,  but  the  failure  to  record,  or  any  error  in  so  recording,  any  such  amount  on  such  Lender’s  Secured
Promissory Note Record shall not limit or otherwise affect the obligations of Borrower under any Secured Promissory Note or any other
Loan Document to make payments of principal of or interest on any Secured Promissory Note when due.  Upon receipt of an affidavit of an
officer of a Lender as to the loss, theft, destruction, or mutilation of its Secured Promissory Note,  Borrower shall issue, in lieu thereof, a
replacement Secured Promissory Note in the same principal amount thereof and of like tenor.

2.5          Fees.  Borrower shall pay to Collateral Agent:

(a)          Good Faith Deposit.  An amount of Fifty Thousand Dollars ($50,000.00) has been received by Collateral Agent
as good faith deposit from Borrower on or about August 21, 2018, which amount shall be applied towards the Lender’s Expenses due on
the Effective Date (it being agreed and understood that Borrower shall remain responsible for all Lender’s Expenses in accordance with
Section 2.5(d) hereof) and the balance, if any, shall be applied towards other payment Obligations of Borrower hereunder in accordance
with the Collateral Agent’s and Lenders’ discretion;

Loan funded hereunder), which shall be due and payable immediately upon the expiration or earlier termination of the First Draw Period or
prepayment  of  the  entire  outstanding  amount  of  the  Term  Loans  pursuant  to  Section  2.2(d)  of  this  Agreement,  if  upon  such  expiration,
earlier  termination  or  prepayment  of  the  entire  outstanding  amount  of  the  Term  Loans  pursuant  to  Section  2.2(d)  of  this  Agreement  the
Borrower has not drawn the full amount of the Term A Loan in accordance with the provisions hereof; and

(f)           Term B Loan Non-Utilization Fee.  A full earned non-utilization fee equal to one percent (1.00%) of the amount
of the Term B Loan not funded hereunder (i.e., the difference between Thirty Five Million Dollars ($35,000,000.00) and the amount of

expiration,  earlier  termination  or  prepayment  of  the  entire  outstanding  amount  of  the  Term  Loans  pursuant  to  Section  2.2(d)  of  this
Agreement the Borrower has not drawn the full amount of the Term B Loan in accordance with the provisions hereof; provided, however,
the non-utilization fee set forth in this Section 2.5(f) shall not become due and payable if the Second Draw Period does not commence.

2.6          Withholding.  Payments received by the Lenders from Borrower hereunder will be made free and clear of and without
deduction  for  any  and  all  present  or  future  taxes,  levies,  imposts,  duties,  deductions,  withholdings,  assessments,  fees  or  other  charges
imposed by any governmental authority (including any interest, additions to tax or penalties applicable thereto).  Specifically, however, if at
any time any Governmental Authority, applicable law, regulation or international agreement requires Borrower to make any withholding or
deduction from any such payment or other sum payable hereunder to the Lenders, Borrower hereby covenants and agrees that the amount
due from Borrower with respect to such payment or other sum payable hereunder will be increased to the extent necessary to ensure that,
after the making of such required withholding or deduction, each Lender receives a net sum equal to the sum which it would have received
had no withholding or deduction been required and Borrower shall pay the full amount withheld or deducted to the relevant Governmental
Authority.  Borrower will, upon request, furnish the Lenders with proof reasonably satisfactory to the Lenders indicating that Borrower has
made such withholding payment; provided, however, that Borrower need not make any withholding payment if the amount or validity of
such withholding payment is contested in good faith by appropriate and timely proceedings and as to which payment in full is bonded or
reserved against by Borrower.  The agreements and obligations of Borrower contained in this Section 2.6 shall survive the termination of
this Agreement.

(a)          receipt by Collateral Agent of an executed Disbursement Letter in the form of Exhibit B attached hereto;

3.4          Covenant to Deliver.  Borrower agrees to deliver to Collateral Agent and the Lenders each item required to be delivered
to  Collateral  Agent  under  this  Agreement  as  a  condition  precedent  to  any  Credit  Extension.    Borrower  expressly  agrees  that  a  Credit

Lender shall credit and/or transfer (as applicable) to the Designated Deposit Account, an amount equal to its Term Loan Commitment.

4.            CREATION OF SECURITY INTEREST

4.1          Grant of Security Interest.  Borrower hereby grants Collateral Agent, for the ratable benefit of the Lenders, to secure
the payment and performance in full of all of the Obligations, a continuing security interest in, and pledges to Collateral Agent, for the
ratable benefit of the Lenders, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and
products thereof. Borrower represents, warrants, and covenants that the security interest granted herein is and shall at all times continue to
be  a  first  priority  perfected  security  interest  in  the  Collateral,  subject  only  to  Permitted  Liens  that  are  permitted  by  the  terms  of  this
Agreement  to  have  priority  to  Collateral  Agent’s  Lien.    If  Borrower  shall  acquire  a  commercial  tort  claim  (as  defined  in  the  Code),
Borrower, shall promptly notify Collateral Agent in a writing signed by Borrower, after Borrower becomes aware of such tort claim, as the
case may be, of the general details thereof (and further details as may be required by Collateral Agent) and grant to Collateral Agent, for
the  ratable  benefit  of  the  Lenders,  in  such  writing  a  security  interest  therein  and  in  the  proceeds  thereof,  all  upon  the  terms  of  this
Agreement, with such writing to be in form and substance reasonably satisfactory to Collateral Agent.

If this Agreement is terminated, Collateral Agent’s Lien in the Collateral shall continue until the Obligations (other than inchoate
indemnity  obligations)  are  repaid  in  full  in  cash.    Upon  payment  in  full  in  cash  of  the  Obligations  (other  than  inchoate  indemnity
obligations) and at such time as the Lenders’ obligation to make Credit Extensions has terminated, Collateral Agent shall, at the sole cost
and expense of Borrower, release its Liens in the Collateral and all rights therein shall revert to Borrower.

4.2          Authorization to File Financing Statements.  Borrower hereby authorizes Collateral Agent to file financing statements
or  take  any  other  action  required  to  perfect  Collateral  Agent’s  security  interests  in  the  Collateral,  without  notice  to  Borrower,  with  all
appropriate jurisdictions to perfect or protect Collateral Agent’s interest or rights under the Loan Documents, including a notice that any
disposition  of  the  Collateral,  except  to  the  extent  permitted  by  the  terms  of  this  Agreement,  by  Borrower,  or  any  other  Person,  shall  be
deemed to violate the rights of Collateral Agent under the Code.

4.3          Pledge of Collateral.  Borrower hereby pledges, assigns and grants to Collateral Agent, for the ratable benefit of the
Lenders,  a  security  interest  in  all  the  Shares,  together  with  all  proceeds  and  substitutions  thereof,  all  cash,  stock  and  other  moneys  and
property  paid  thereon,  all  rights  to  subscribe  for  securities  declared  or  granted  in  connection  therewith,  and  all  other  cash  and  noncash
proceeds of the foregoing, as security for the performance of the Obligations.  On the Effective Date, or, to the extent not certificated as of
the Effective Date, within twenty (20) days of the certification of any Shares, the certificate or certificates for the Shares will be delivered
to Collateral Agent, accompanied by an instrument of assignment duly executed in blank by Borrower.  To the extent required by the terms
and conditions governing the Shares, Borrower shall cause the books of each entity whose Shares are part of the Collateral and any transfer
agent to reflect the pledge of the Shares.  Upon the occurrence and during the continuance of an Event of Default hereunder, Collateral
Agent  may  effect  the  transfer  of  any  securities  included  in  the  Collateral  (including  but  not  limited  to  the  Shares)  into  the  name  of
Collateral Agent and cause new (as applicable) certificates representing such securities to be issued in the name of Collateral Agent or its
transferee.    Borrower  will  execute  and  deliver  such  documents,  and  take  or  cause  to  be  taken  such  actions,  as  Collateral  Agent  may
reasonably request to perfect or continue the perfection of Collateral Agent’s security interest in the Shares.  Unless an Event of Default
shall  have  occurred  and  be  continuing,  Borrower  shall  be  entitled  to  exercise  any  voting  rights  with  respect  to  the  Shares  and  to  give
consents, waivers and ratifications in respect thereof, provided that no vote shall be cast or consent, waiver or ratification given or action
taken which would be inconsistent with any of the terms of this Agreement or which would constitute or create any violation of any of such
terms.  All such rights to vote and give consents, waivers and ratifications shall terminate upon the occurrence and continuance of an Event
of Default.

good standing as a Registered Organization in its jurisdictions of organization or formation and Borrower and each of its Subsidiaries is
qualified and licensed to do business and is in good standing in any jurisdiction in which the conduct of its businesses or its ownership of
property  requires  that  it  be  qualified  except  where  the  failure  to  do  so  could  not  reasonably  be  expected  to  have  a  Material  Adverse
Change.    In  connection  with  this  Agreement,  Borrower  and  each  of  its  Subsidiaries  has  delivered  to  Collateral  Agent  a  completed
perfection certificate signed by an officer of Borrower or such Subsidiary (each as updated from time to time, as permitted hereunder, a
“Perfection Certificate” and collectively, the “Perfection Certificates”).  Borrower represents and warrants that (a) Borrower and each of
its Subsidiaries’ exact legal name is that which is indicated on its respective Perfection Certificate and on the signature page of each Loan
Document to which it is a party; (b) Borrower and each of its Subsidiaries is an organization of the type and is organized in the jurisdiction
set  forth  on  its  respective  Perfection  Certificate;  (c)  each  Perfection  Certificate  accurately  sets  forth  each  of  Borrower’s  and  its
Subsidiaries’  organizational  identification  number  or  accurately  states  that  Borrower  or  such  Subsidiary  has  none;  (d)  each  Perfection

well as Borrower’s and each of its Subsidiaries’ mailing address (if different than its chief executive office); (e) Borrower and each of its
Subsidiaries  (and  each  of  its  respective  predecessors)  have  not,  in  the  past  five  (5)  years,  changed  its  jurisdiction  of  organization,

Perfection  Certificates  pertaining  to  Borrower  and  each  of  its  Subsidiaries,  is  accurate  and  complete  in  all  material  respects  (it  being

Certificates (including the information set forth in clause (d) above) after the Effective Date to the extent permitted by one or more specific
provisions in this Agreement); such updated Perfection Certificates subject to the review and approval of Collateral Agent.  If Borrower or
any  of  its  Subsidiaries  is  not  now  a  Registered  Organization  but  later  becomes  one,  Borrower  shall  notify  Collateral  Agent  of  such
occurrence  and  provide  Collateral  Agent  with  such  Person’s  organizational  identification  number  within  five  (5)  Business  Days  of

respective  Operating  Documents,  (ii)  contravene,  conflict  with,  constitute  a  default  under  or  violate  any  material  Requirement  of  Law

require any action by, filing, registration, or qualification with, or Governmental Approval from, any Governmental Authority (except such
Governmental  Approvals  which  have  already  been  obtained  and  are  in  full  force  and  effect)  or  are  being  obtained  pursuant  to
Section 6.1(b), or (v) constitute an event of default under any material agreement by which Borrower or any of such Subsidiaries, or their
respective properties, is bound.  Neither Borrower nor any of its Subsidiaries is in default under any agreement to which it is a party or by
which it or any of its assets is bound in which such default could reasonably be expected to have a Material Adverse Change.

or  such  Subsidiaries’  interest  in  such  material  license  or  material  agreement  or  any  other  property,  or  (ii)  for  which  a  default  under  or
termination of could interfere with Collateral Agent’s or any Lender’s right to sell any Collateral.  Borrower shall provide written notice to

to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (b) notifies Collateral Agent in writing of the

of  its  Subsidiaries  fails  to  obtain  insurance  as  required  under  this  Section  6.5  or  to  pay  any  amount  or  furnish  any  required  proof  of
payment to third persons, Collateral Agent and/or any Lender may make, at Borrower’s expense, all or part of such payment or obtain such

intends to add any new offices or business locations, including warehouses, or otherwise store any portion of the Collateral with, or deliver
any  portion  of  the  Collateral  to,  a  bailee,  in  each  case  pursuant  to  Section  7.2,  then  Borrower  or  such  Subsidiary  will  first  receive  the

Indebtedness in an amount in excess of Two Hundred Fifty Thousand Dollars ($250,000.00) or that could reasonably be expected to have a
Material  Adverse  Change;  provided,  however,  that  the  Event  of  Default  under  this  Section  8.6  caused  by  the  occurrence  of  a  breach  or
default under such other agreement shall be cured or waived for purposes of this Agreement upon Collateral Agent receiving written notice
from the party asserting such breach or default of such cure or waiver of the breach or default under such other agreement, if at the time of
such  cure  or  waiver  under  such  other  agreement  (x)  Collateral  Agent  or  any  Lender  has  not  declared  an  Event  of  Default  under  this
Agreement and/or exercised any rights with respect thereto; (y) any such cure or waiver does not result in an Event of Default under any
other provision of this Agreement or any Loan Document; and (z) in connection with any such cure or waiver under such other agreement,

liability  has  been  accepted  by  such  insurance  carrier)  shall  be  rendered  against  Borrower  or  any  of  its  Subsidiaries  and  shall  remain
unsatisfied, unvacated, or unstayed for a period of ten (10) days after the entry thereof (provided that no Credit Extensions will be made

makes any representation, warranty, or other statement now or later in this Agreement, any Loan Document or in any writing delivered to
Collateral Agent and/or Lenders or to induce Collateral Agent and/or the Lenders to enter this Agreement or any Loan Document, and such
representation, warranty, or other statement is incorrect in any material respect when made;

8.9          Subordinated Debt.  A default or breach occurs under any agreement between Borrower or any of its Subsidiaries and
any  creditor  of  Borrower  or  any  of  its  Subsidiaries  that  signed  a  subordination,  intercreditor,  or  other  similar  agreement  with  Collateral
Agent or the Lenders, or any creditor that has signed such an agreement with Collateral Agent or the Lenders breaches any terms of such
agreement;

non‑renewal has resulted in or could reasonably be expected to result in a Material Adverse Change; or

8.12        Lien Priority.  Any Lien created hereunder or by any other Loan Document shall at any time fail to constitute a valid

8.13        Delisting.  The shares of common stock of Borrower are delisted from NASDAQ Stock Market because of failure to
comply with continued listing standards thereof or due to a voluntary delisting which results in such shares not being listed on any other

casualty insurance coverage, or which, in the judgment of Collateral Agent, could reasonably be expected to result in a material diminution
in value of the Collateral.

9.2          Power of Attorney.  Borrower hereby irrevocably appoints Collateral Agent as its lawful attorney‑in‑fact, exercisable
upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s or any of its Subsidiaries’ name on any
checks or other forms of payment or security; (b) sign Borrower’s or any of its Subsidiaries’ name on any invoice or bill of lading for any
Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for
amounts and on terms Collateral Agent determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies;
(e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based
thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of Collateral Agent or
a third party as the Code or any applicable law permits.  Borrower hereby appoints Collateral Agent as its lawful attorney‑in‑fact to sign
Borrower’s or any of its Subsidiaries’ name on any documents necessary to perfect or continue the perfection of Collateral Agent’s security
interest  in  the  Collateral  regardless  of  whether  an  Event  of  Default  has  occurred  until  all  Obligations  (other  than  inchoate  indemnity
obligations)  have  been  satisfied  in  full  and  Collateral  Agent  and  the  Lenders  are  under  no  further  obligation  to  make  Credit  Extensions
hereunder.  Collateral Agent’s foregoing appointment as Borrower’s or any of its Subsidiaries’ attorney in fact, and all of Collateral Agent’s
rights and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate indemnity obligations) have been fully
repaid and performed and Collateral Agent’s and the Lenders’ obligation to provide Credit Extensions terminates.

9.3          Protective Payments.  If Borrower or any of its Subsidiaries fail to obtain the insurance called for by Section 6.5 or fails
to  pay  any  premium  thereon  or  fails  to  pay  any  other  amount  which  Borrower  or  any  of  its  Subsidiaries  is  obligated  to  pay  under  this
Agreement or any other Loan Document, Collateral Agent may obtain such insurance or make such payment, and all amounts so paid by
Collateral  Agent  are  Lenders’  Expenses  and  immediately  due  and  payable,  bearing  interest  at  the  Default  Rate,  and  secured  by  the
Collateral.  Collateral Agent will make reasonable efforts to provide Borrower with notice of Collateral Agent obtaining such insurance or

making such payment at the time it is obtained or paid or within a reasonable time thereafter.  No such payments by Collateral Agent are
deemed an agreement to make similar payments in the future or Collateral Agent’s waiver of any Event of Default.

9.4          Application of Payments and Proceeds.  Notwithstanding anything to the contrary contained in this Agreement, upon
the occurrence and during the continuance of an Event of Default, (a) Borrower irrevocably waives the right to direct the application of any
and all payments at any time or times thereafter received by Collateral Agent from or on behalf of Borrower or any of its Subsidiaries of all
or any part of the Obligations, and, as between Borrower on the one hand and Collateral Agent and Lenders on the other, Collateral Agent
shall have the continuing and exclusive right to apply and to reapply any and all payments received against the Obligations in such manner
as Collateral Agent may deem advisable notwithstanding any previous application by Collateral Agent, and (b) the proceeds of any sale of,
or other realization upon all or any part of the Collateral shall be applied: first, to the Lenders’ Expenses; second, to accrued and unpaid
interest on the Obligations (including any interest which, but for the provisions of the United States Bankruptcy Code, would have accrued
on  such  amounts);  third,  to  the  principal  amount  of  the  Obligations  outstanding;  and  fourth,  to  any  other  indebtedness  or  obligations  of
Borrower owing to Collateral Agent or any Lender under the Loan Documents.  Any balance remaining shall be delivered to Borrower or
to  whoever  may  be  lawfully  entitled  to  receive  such  balance  or  as  a  court  of  competent  jurisdiction  may  direct.    In  carrying  out  the
foregoing,  (x)  amounts  received  shall  be  applied  in  the  numerical  order  provided  until  exhausted  prior  to  the  application  to  the  next
succeeding category, and (y) each of the Persons entitled to receive a payment in any particular category shall receive an amount equal to
its pro rata share of amounts available to be applied pursuant thereto for such category.  Any reference in this Agreement to an allocation
between or sharing by the Lenders of any right, interest or obligation “ratably,” “proportionally” or in similar terms shall refer to Pro Rata
Share unless expressly provided otherwise.  Collateral Agent, or if applicable, each Lender, shall promptly remit to the other Lenders such
sums  as  may  be  necessary  to  ensure  the  ratable  repayment  of  each  Lender’s  portion  of  any  Term  Loan  and  the  ratable  distribution  of
interest, fees and reimbursements paid or made by Borrower.  Notwithstanding the foregoing, a Lender receiving a scheduled payment shall
not be responsible for determining whether the other Lenders also received their scheduled payment on such date; provided, however, if it
is later determined that a Lender received more than its ratable share of scheduled payments made on any date or dates, then such Lender
shall remit to Collateral Agent or other Lenders such sums as may be necessary to ensure the ratable payment of such scheduled payments,
as instructed by Collateral Agent.  If any payment or distribution of any kind or character, whether in cash, properties or securities, shall be
received by a Lender in excess of its ratable share, then the portion of such payment or distribution in excess of such Lender’s ratable share
shall be received by such Lender in trust for and shall be promptly paid over to the other Lender for application to the payments of amounts
due on the other Lenders’ claims.  To the extent any payment for the account of Borrower is required to be returned as a voidable transfer
or otherwise, the Lenders shall contribute to one another as is necessary to ensure that such return of payment is on a pro rata basis.  If any
Lender shall obtain possession of any Collateral, it shall hold such Collateral for itself and as agent and bailee for Collateral Agent and
other Lenders for purposes of perfecting Collateral Agent’s security interest therein.

9.5                    Liability  for  Collateral.    So  long  as  Collateral  Agent  and  the  Lenders  comply  with  reasonable  banking  practices
regarding the safekeeping of the Collateral in the possession or under the control of Collateral Agent and the Lenders, Collateral Agent and
the Lenders shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any
diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person.  Borrower bears all
risk of loss, damage or destruction of the Collateral.

9.6          No Waiver; Remedies Cumulative.  Failure by Collateral Agent or any Lender, at any time or times, to require strict
performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of
Collateral Agent or any Lender thereafter to demand strict performance and compliance herewith or therewith.  No waiver hereunder shall
be effective unless signed by Collateral Agent and the Required Lenders and then is only effective for the specific instance and purpose for
which it is given.  The rights and remedies of Collateral Agent and the Lenders under this Agreement and the other Loan

Documents are cumulative.  Collateral Agent and the Lenders have all rights and remedies provided under the Code, any applicable law, by
law, or in equity.  The exercise by Collateral Agent or any Lender of one right or remedy is not an election, and Collateral Agent’s or any
Lender’s waiver of any Event of Default is not a continuing waiver.  Collateral Agent’s or any Lender’s delay in exercising any remedy is
not a waiver, election, or acquiescence.

9.7          Demand Waiver.  Borrower waives, to the fullest extent permitted by law, demand, notice of default or dishonor, notice
of  payment  and  nonpayment,  notice  of  any  default,  nonpayment  at  maturity,  release,  compromise,  settlement,  extension,  or  renewal  of
accounts,  documents,  instruments,  chattel  paper,  and  guarantees  held  by  Collateral  Agent  or  any  Lender  on  which  Borrower  or  any
Subsidiary is liable.

All  notices,  consents,  requests,  approvals,  demands,  or  other  communication  (collectively,  “Communication”)  by  any  party  to

11.          CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER

in 

to 

the  exclusive 

jurisdiction  of 

New York law governs the Loan Documents without regard to principles of conflicts of law.  Borrower, Lenders and Collateral Agent each
submit 
the  City  of  New  York,  Borough  of
the  State  and  Federal  courts 
Manhattan.  NOTWITHSTANDING THE FOREGOING, COLLATERAL AGENT AND THE LENDERS SHALL HAVE THE RIGHT
TO  BRING  ANY  ACTION  OR  PROCEEDING  AGAINST  BORROWER  OR  ITS  PROPERTY  IN  THE  COURTS  OF  ANY  OTHER
JURISDICTION  WHICH  COLLATERAL  AGENT  AND  THE  LENDERS  (IN  ACCORDANCE  WITH  THE  PROVISIONS  OF
SECTION  9.1)  DEEM  NECESSARY  OR  APPROPRIATE  TO  REALIZE  ON  THE  COLLATERAL  OR  TO  OTHERWISE  ENFORCE
COLLATERAL AGENT’S AND THE LENDERS’ RIGHTS AGAINST BORROWER OR ITS PROPERTY.  Borrower expressly submits
and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any objection
that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of
such  legal  or  equitable  relief  as  is  deemed  appropriate  by  such  court.    Borrower  hereby  waives  personal  service  of  the  summons,
complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be
made by registered or certified mail addressed to Borrower at the address set forth in, or subsequently provided by Borrower in accordance
with, Section 10 of this Agreement and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual
receipt  thereof  or  three  (3)  days  after  deposit  in  the  U.S.  mails,  first  class,  registered  or  certified  mail  return  receipt  requested,  proper
postage prepaid.

TO  THE  FULLEST  EXTENT  PERMITTED  BY  APPLICABLE  LAW,  BORROWER,  COLLATERAL  AGENT,  AND  THE
LENDERS EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF
OR  BASED  UPON  THIS  AGREEMENT,  THE  LOAN  DOCUMENTS  OR  ANY  CONTEMPLATED  TRANSACTION,
INCLUDING  CONTRACT,  TORT,  BREACH  OF  DUTY  AND  ALL  OTHER  CLAIMS.  THIS  WAIVER  IS  A  MATERIAL
INDUCEMENT FOR EACH PARTY TO ENTER INTO THIS AGREEMENT.  EACH PARTY HAS REVIEWED THIS WAIVER
WITH ITS COUNSEL.

12.          GENERAL PROVISIONS

12.1        Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each
party.  Borrower may not transfer, pledge or assign this Agreement or any rights or obligations under it without Collateral Agent’s and each
Lender’s  prior  written  consent  (which  may  be  granted  or  withheld  in  Collateral  Agent’s  and  each  Lender’s  discretion,  subject  to
Section 12.6).  The Lenders have the right, without the consent of or notice to Borrower, to sell, transfer, assign, pledge, negotiate, or grant
participation in (any such sale, transfer, assignment, negotiation, or grant of a participation, a “Lender Transfer”) all or any part of, or any
interest in, the Lenders’ obligations, rights, and benefits under this Agreement and the other Loan Documents; provided,  however, that any
such Lender Transfer (other than a transfer, pledge, sale or assignment to an Eligible Assignee) of its obligations, rights, and benefits under
this Agreement and the other Loan Documents shall require the prior written consent of the Required Lenders (such approved assignee, an
“Approved  Lender”).    Borrower  and  Collateral  Agent  shall  be  entitled  to  continue  to  deal  solely  and  directly  with  such  Lender  in
connection with the interests so assigned until Collateral Agent shall have received and accepted an effective assignment agreement in form
satisfactory  to  Collateral  Agent  executed,  delivered  and  fully  completed  by  the  applicable  parties  thereto,  and  shall  have  received  such
other  information  regarding  such  Eligible  Assignee  or  Approved  Lender  as  Collateral  Agent  reasonably  shall  require.    Notwithstanding
anything to the contrary contained herein, so long as no Event of Default has occurred and is continuing, no Lender Transfer (other than a
Lender Transfer in connection with (x) assignments by a Lender due to a forced divestiture at the request of any regulatory agency; or (y)
upon  the  occurrence  of  a  default,  event  of  default  or  similar  occurrence  with  respect  to  a  Lender’s  own  financing  or  securitization
transactions)  shall  be  permitted,  without  Borrower’s  consent,  to  any  Person  which  is  an  Affiliate  or  Subsidiary  of  Borrower,  a  direct
competitor of Borrower or a vulture hedge fund, each as determined by Collateral Agent.

12.2        Indemnification.  Borrower agrees to indemnify, defend and hold Collateral Agent and the Lenders and their respective
directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Collateral Agent or the Lenders (each,
an “Indemnified Person”) harmless against:  (a) all obligations, demands, claims, and liabilities (collectively, “Claims”) asserted by any
other  party  in  connection  with;  related  to;  following;  or  arising  from,  out  of  or  under,  the  transactions  contemplated  by  the  Loan
Documents; and (b) all losses or Lenders’ Expenses incurred, or paid by Indemnified Person in connection with; related to; following; or
arising  from,  out  of  or  under,  the  transactions  contemplated  by  the  Loan  Documents  between  Collateral  Agent,  and/or  the  Lenders  and
Borrower  (including  reasonable  attorneys’  fees  and  expenses),  except  for  Claims  and/or  losses  directly  caused  by  such  Indemnified
Person’s    gross  negligence  or  willful  misconduct.    Borrower  hereby  further  indemnifies,  defends  and  holds  each  Indemnified  Person
harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses
and  disbursements  of  any  kind  or  nature  whatsoever  (including  the  fees  and  disbursements  of  counsel  for  such  Indemnified  Person)  in
connection  with  any  investigative,  response,  remedial,  administrative  or  judicial  matter  or  proceeding,  whether  or  not  such  Indemnified
Person  shall  be  designated  a  party  thereto  and  including  any  such  proceeding  initiated  by  or  on  behalf  of  Borrower,  and  the  reasonable
expenses  of  investigation  by  engineers,  environmental  consultants  and  similar  technical  personnel  and  any  commission,  fee  or
compensation claimed by any broker (other than any broker retained by Collateral Agent or Lenders) asserting any right to payment for the
transactions contemplated hereby which may be imposed on, incurred by or asserted against such Indemnified Person as a result of or in
connection with the transactions contemplated hereby and the use or intended use of the proceeds of the loan proceeds except for liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits,  claims,  costs,  expenses  and  disbursements  directly  caused  by  such
Indemnified Person’s gross negligence or willful misconduct.

12.3        Time of Essence.  Time is of the essence for the performance of all Obligations in this Agreement.

12.4        Severability of Provisions.  Each provision of this Agreement is severable from every other provision in determining

the enforceability of any provision.

12.5        Correction of Loan Documents.  Collateral Agent and the Lenders may correct patent errors and fill in any blanks in

this Agreement and the other Loan Documents consistent with the agreement of the parties.

12.6        Amendments in Writing; Integration.  (a) No amendment, modification, termination or waiver of any provision of this
Agreement or any other Loan Document, no approval or consent thereunder, or any consent to any departure by Borrower or any of its
Subsidiaries therefrom, shall in any event be effective unless the same shall be in writing and signed by Borrower, Collateral Agent and the
Required Lenders provided that:

(i)           no such amendment, waiver or other modification that would have the effect of increasing or reducing
a Lender’s Term Loan Commitment or Commitment Percentage shall be effective as to such Lender without such Lender’s written consent;

shall be effective without Collateral Agent’s written consent or signature;

(ii)          no such amendment, waiver or modification that would affect the rights and duties of Collateral Agent

(iii)                  no  such  amendment,  waiver  or  other  modification  shall,  unless  signed  by  all  the  Lenders  directly
affected thereby, (A) reduce the principal of, rate of interest on or any fees with respect to any Term Loan or forgive any principal, interest
(other than default interest) or fees (other than late charges) with respect to any Term Loan (B) postpone the date fixed for, or waive, any
payment of principal of any Term Loan or of interest on any Term Loan (other than default interest) or any fees provided for hereunder
(other  than  late  charges  or  for  any  termination  of  any  commitment);  (C)  change  the  definition  of  the  term  “Required Lenders”  or  the
percentage  of  Lenders  which  shall  be  required  for  the  Lenders  to  take  any  action  hereunder;  (D)  release  all  or  substantially  all  of  any
material portion of the Collateral, authorize Borrower to sell or otherwise dispose of all or substantially all or any material portion of the
Collateral or release any Guarantor of all or any portion of the

expressly  permitted  under  this  Agreement  or  the  other  Loan  Documents  (including  in  connection  with  any  disposition  permitted
hereunder); (E) amend, waive or otherwise modify this Section 12.6 or the definitions of the terms used in this Section 12.6 insofar as the
definitions affect the substance of this Section 12.6; (F) consent to the assignment, delegation or other transfer by Borrower of any of its
rights and obligations under any Loan Document or release Borrower of its payment obligations under any Loan Document, except, in each
case  with  respect  to  this  clause  (F),  pursuant  to  a  merger  or  consolidation  permitted  pursuant  to  this  Agreement;  (G)  amend  any  of  the
provisions  of  Section  9.4  or  amend  any  of  the  definitions  of  Pro  Rata  Share,  Term  Loan  Commitment,  Commitment  Percentage  or  that
provide for the Lenders to receive their Pro Rata Shares of any fees, payments, setoffs or proceeds of Collateral hereunder; (H) subordinate
the Liens granted in favor of Collateral Agent securing the Obligations; or (I) amend any of the provisions of Section 12.10.  It is hereby
understood  and  agreed  that  all  Lenders  shall  be  deemed  directly  affected  by  an  amendment,  waiver  or  other  modification  of  the  type
described in the preceding clauses (C), (D), (E), (F), (G) and (H) of the preceding sentence;

(iv)         the provisions of the foregoing clauses (i), (ii) and (iii) are subject to the provisions of any interlender
or agency agreement among the Lenders and Collateral Agent pursuant to which any Lender may agree to give its consent in connection
with any amendment, waiver or modification of the Loan Documents only in the event of the unanimous agreement of all Lenders.

(b)                    Other  than  as  expressly  provided  for  in  Section  12.6(a)(i)‑(iii),  Collateral  Agent  may,  if  requested  by  the
Required Lenders, from time to time designate covenants in this Agreement less restrictive by notification to a representative of Borrower.

(c)          This Agreement and the Loan Documents represent the entire agreement about this subject matter and supersede
prior negotiations or agreements.  All prior agreements, understandings, representations, warranties, and negotiations between the parties
about the subject matter of this Agreement and the Loan Documents merge into this Agreement and the Loan Documents.

12.7        Counterparts.  This Agreement may be executed in any number of counterparts and by different parties on separate

counterparts, each of which, when executed and delivered, is an original, and all taken together, constitute one Agreement.

12.8        Survival.  All covenants, representations and warranties made in this Agreement continue in full force and effect until
this  Agreement  has  terminated  pursuant  to  its  terms  and  all  Obligations  (other  than  inchoate  indemnity  obligations  and  any  other
obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied.  The obligation of Borrower in
Section 12.2 to indemnify each Lender and Collateral Agent, as well as the confidentiality provisions in Section 12.9 below, shall survive
until the statute of limitations with respect to such claim or cause of action shall have run.

12.9        Confidentiality.  In handling any confidential information of Borrower, the Lenders and Collateral Agent shall exercise
the same degree of care that it exercises for their own proprietary information, but disclosure of information may be made: (a) subject to
the  terms  and  conditions  of  this  Agreement,  to  the  Lenders’  and  Collateral  Agent’s  Subsidiaries  or  Affiliates,  or  in  connection  with  a
Lender’s  own  financing  or  securitization  transactions  and  upon  the  occurrence  of  a  default,  event  of  default  or  similar  occurrence  with
respect to such financing or securitization transaction; (b) to prospective transferees (other than those identified in (a) above) or purchasers
of any interest in the Credit Extensions (provided, however, the Lenders and Collateral Agent shall, except upon the occurrence and during
the continuance of an Event of Default, obtain such prospective transferee’s or purchaser’s agreement to the terms of this provision or to
similar confidentiality terms); (c) as required by law, regulation, subpoena, or other order; (d) to Lenders’ or Collateral Agent’s regulators
or as otherwise required in connection with an examination or audit; (e) as Collateral Agent reasonably considers appropriate in exercising
remedies under the Loan Documents; and (f) to third party service providers of the Lenders and/or Collateral Agent so long as such service

with terms no less restrictive than those contained herein. Confidential information does not include information that either: (i) is in the
public domain or in the Lenders’ and/or Collateral Agent’s possession when disclosed to the Lenders and/or Collateral Agent, or becomes
part of the public domain after disclosure to the Lenders and/or Collateral Agent through no fault of the Lenders and/or Collateral Agent in
breach of this Agreement; or (ii) is disclosed to the Lenders and/or Collateral Agent by a third party, if the Lenders and/or Collateral Agent
does not know that the third party is prohibited from disclosing the information.  Collateral Agent and the Lenders may use confidential
information  for  any  purpose,  including,  without  limitation,  for  the  development  of  client  databases,  reporting  purposes,  and  market
analysis.  The provisions of the immediately preceding sentence shall survive the termination of this Agreement.  The agreements provided
under  this  Section  12.9  supersede  all  prior  agreements,  understanding,  representations,  warranties,  and  negotiations  between  the  parties
about the subject matter of this Section 12.9.

12.10      Right of Set Off.  Borrower hereby grants to Collateral Agent and to each Lender, a lien, security interest and right of set
off  as  security  for  all  Obligations  to  Collateral  Agent  and  each  Lender  hereunder,  whether  now  existing  or  hereafter  arising  upon  and
against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Collateral Agent
or the Lenders or any entity under the control of Collateral Agent or the Lenders (including a Collateral Agent affiliate) or in transit to any
of them.  At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Collateral Agent
or  the  Lenders  may  set  off  the  same  or  any  part  thereof  and  apply  the  same  to  any  liability  or  obligation  of  Borrower  even  though
unmatured  and  regardless  of  the  adequacy  of  any  other  collateral  securing  the  Obligations.   ANY  AND  ALL  RIGHTS  TO  REQUIRE
COLLATERAL  AGENT  TO  EXERCISE  ITS  RIGHTS  OR  REMEDIES  WITH  RESPECT  TO  ANY  OTHER  COLLATERAL  WHICH

WAIVED.

12.11            Cooperation  of  Borrower.    If  necessary,  Borrower  agrees  to  (i)  execute  any  documents  (including  new  Secured
Promissory  Notes)  reasonably  required  to  effectuate  and  acknowledge  each  assignment  of  a  Term  Loan  Commitment  or  Loan  to  an
assignee  in  accordance  with  Section  12.1,  (ii)  make  Borrower’s  management  available  to  meet  with  Collateral  Agent  and  prospective
participants and assignees of Term Loan Commitments or Credit Extensions (which meetings shall be conducted no more often than twice
every  twelve  months  unless  an  Event  of  Default  has  occurred  and  is  continuing),  and  (iii)  assist  Collateral  Agent  or  the  Lenders  in  the
preparation  of  information  relating  to  the  financial  affairs  of  Borrower  as  any  prospective  participant  or  assignee  of  a  Term  Loan
Commitment or Term Loan reasonably may request. Subject to the provisions of Section 12.9, Borrower authorizes each Lender to disclose
to any prospective participant or assignee of a Term Loan Commitment, any and all information in such Lender’s possession concerning
Borrower and its financial affairs which has been delivered to such Lender by or on behalf of Borrower pursuant to this Agreement, or

EXHIBIT A

Description of Collateral

The Collateral consists of all of Borrower’s right, title and interest in and to the following personal property:

All  goods,  Accounts  (including  health‑care  receivables),  Equipment,  Inventory,  contract  rights  or  rights  to  payment  of  money,
leases,  license  agreements,  franchise  agreements,  General  Intangibles  (except  as  noted  below),  commercial  tort  claims,  documents,
instruments  (including  any  promissory  notes),  chattel  paper  (whether  tangible  or  electronic),  cash,  deposit  accounts  and  other  Collateral
Accounts, all certificates of deposit, fixtures, letters of credit rights (whether or not the letter of credit is evidenced by a writing), securities,
and all other investment property, supporting obligations, and financial assets, whether now owned or hereafter acquired, wherever located;
and

All  Borrower’s  Books  relating  to  the  foregoing,  and  any  and  all  claims,  rights  and  interests  in  any  of  the  above  and  all

proceeds of any or all of the foregoing.

Notwithstanding  the  foregoing,  the  Collateral  does  not  include  (i)  any  Intellectual  Property;  provided,  however,  the  Collateral

that a security interest in the underlying Intellectual Property is necessary to have a security interest in such Accounts and such property
that  are  proceeds  of  Intellectual  Property,  then  the  Collateral  shall  automatically,  and  effective  as  of  the  Effective  Date,  include  the
Intellectual Property to the extent necessary to permit perfection of Collateral Agent’s security interest in such Accounts and such other
property  of  Borrower  that  are  proceeds  of  the  Intellectual  Property;  (ii)  more  than  sixty  five  percent  (65%)  of  the  Shares  of  a  Foreign
Subsidiary, if Borrower demonstrates to Collateral Agent’s reasonable satisfaction that a pledge of more than sixty five percent (65%) of

SECURED PARTY: OXFORD FINANCE LLC,  

[BORROWER] 

as Collateral Agent

EXHIBIT A TO UCC FINANCING STATEMENT

Description of Collateral

The Collateral consists of all of Debtor’s right, title and interest in and to the following personal property:

All  goods,  Accounts  (including  health‑care  receivables),  Equipment,  Inventory,  contract  rights  or  rights  to  payment  of  money,
leases,  license  agreements,  franchise  agreements,  General  Intangibles  (except  as  noted  below),  commercial  tort  claims,  documents,
instruments  (including  any  promissory  notes),  chattel  paper  (whether  tangible  or  electronic),  cash,  deposit  accounts  and  other  Collateral
Accounts, all certificates of deposit, fixtures, letters of credit rights (whether or not the letter of credit is evidenced by a writing), securities,
and all other investment property, supporting obligations, and financial assets, whether now owned or hereafter acquired, wherever located;
and

All  Borrower’s  Books  relating  to  the  foregoing,  and  any  and  all  claims,  rights  and  interests  in  any  of  the  above  and  all
substitutions for, additions, attachments, accessories, accessions and improvements to and replacements, products, proceeds and insurance
proceeds of any or all of the foregoing.

Notwithstanding  the  foregoing,  the  Collateral  does  not  include  (i)  any  Intellectual  Property;  provided,  however,  the  Collateral
shall include all Accounts and all proceeds of Intellectual Property.  If a judicial authority (including a U.S. Bankruptcy Court) would hold
that a security interest in the underlying Intellectual Property is necessary to have a security interest in such Accounts and such property
that  are  proceeds  of  Intellectual  Property,  then  the  Collateral  shall  automatically,  and  effective  as  of  the  Effective  Date,  include  the
Intellectual Property to the extent necessary to permit perfection of Collateral Agent’s security interest in such Accounts and such other
property  of  Borrower  that  are  proceeds  of  the  Intellectual  Property;  (ii)  more  than  sixty  five  percent  (65%)  of  the  Shares  of  a  Foreign
