Item 1. Business

Overview

PART I

We  are  a  clinical-stage  biopharmaceutical  company  focused  on  developing  novel  drug  candidates  for  immuno-
inflammatory  diseases.    In  addition  to  developing  our  novel  drug  candidates,  we  are  pursuing  strategic  alternatives,
including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval for and/or commercialize our novel drug candidates.

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,
including KINect, a proprietary drug discovery platform. This allowed us to bring early-stage research and development
activities  in-house  that  we  previously  outsourced  to  third  parties.  We  leverage  these  capabilities  and  KINect  to  identify
potential  drug  candidates  that  we  may  develop  independently  or  in  collaboration  with  third  parties.  As  part  of  the
Confluence  acquisition  we  also  acquired  our  investigational  drug  candidates  zunsemetinib,  an  inhibitor  of  the  mitogen-
activated protein kinase-activated protein kinase 2, or MK2, signaling pathway, ATI-1777, a topical “soft” Janus kinase, or
JAK, 1/3 inhibitor, and ATI-2138, an inhibitor of interleukin-2-inducible T cell kinase, or ITK. We also earn revenue from
Confluence’s provision of contract research services to third parties. 

Our Drug Candidates

Our  pipeline  of  drug  candidates  that  we  are  currently  developing  is  summarized  in  the  table  below.  These

investigational drugs were developed internally utilizing our proprietary KINect drug discovery platform.

Clinical Programs

Zunsemetinib, an Investigational Oral MK2 Inhibitor

We are developing zunsemetinib, an investigational oral MK2 inhibitor, as a potential treatment for rheumatoid
arthritis, hidradenitis suppurativa and psoriatic arthritis. MK2 is a key regulator of pro-inflammatory mediators including
TNFα, IL1β, IL6, IL8, IL17 and other essential pathogenic signals in chronic immuno-inflammatory diseases, as well as in
oncology.    As  an  oral  drug  candidate,  we  are  developing  zunsemetinib  as  a  potential  alternative  to  injectable  anti-
TNF/IL1/IL6/IL17  biologics  and  JAK  inhibitors  for  treating  certain  immuno-inflammatory  diseases.  Zunsemetinib  has
been adopted as the nonproprietary name for ATI-450.

Moderate to Severe Rheumatoid Arthritis

In  March  2020,  we  initiated  a  12-week,  Phase  2a,  multicenter,  randomized,  investigator  and  patient-blind,
sponsor-unblinded, parallel group, placebo-controlled clinical trial to investigate the safety, tolerability, pharmacokinetics
and pharmacodynamics of zunsemetinib in subjects with moderate to severe rheumatoid arthritis (ATI-450-RA-201). In the
trial, which consisted of a 12-week treatment period and a 4-week follow-up period, 19 subjects were randomized in a 3:1
ratio and received either zunsemetinib at 50 mg twice daily or placebo, in combination with methotrexate, for 12 weeks.

The final per-protocol analysis, which consisted of the 17 subjects who completed the treatment period (15 in the
treatment arm and two in the placebo arm), showed that zunsemetinib demonstrated durable clinical activity, as defined by
a marked and sustained reduction in DAS28-CRP and improvement of American College of Rheumatology 20%/50%/70%
(ACR20/50/70)  responses  over  12  weeks.  Zunsemetinib  was  generally  well  tolerated.  All  adverse  events  were  mild  to
moderate.  The  most  common  adverse  events  (each  reported  in  2  subjects)  were  urinary  tract  infection,  or  UTI,  and
ventricular  extrasystoles,  all  of  which  were  determined  to  be  unrelated  to  treatment  except  for  one  UTI.  Two  subjects
withdrew from the trial during the treatment period, one in the treatment arm and one in the placebo arm. The subject in the
treatment  arm  withdrew  due  to  an  elevated  creatine  phosphokinase,  or  CPK,  level,  which  was  determined  by  the  site
investigator to be treatment-related; this subject also had palpitations and ventricular extrasystoles, which were unrelated to
the trial medication. The subject in the placebo arm withdrew as a result of prohibited medication needed to treat muscle
strain.  There  was  also  one  non-treatment-related  serious  adverse  event  (COVID-19)  reported  in  the  4-week  follow-up
period of the trial in a subject who was no longer receiving treatment; the subject withdrew during the 4-week follow-up
period of the trial.

A  final  analysis,  which  consisted  of  the  17  subjects,  of  ex  vivo  stimulated  cytokines  from  blood  samples  taken
from the treatment arm showed a marked and durable inhibition of TNFα, IL1β, IL6, and IL8 over the 12-week treatment
period. Similarly, analysis of endogenous inflammation biomarkers also demonstrated a marked and sustained inhibition of
median concentrations of hsCRP, TNFα, IL6, IL8 and MIP1β in the treatment arm over the 12-week period.

In  December  2021,  we  initiated  a  Phase  2b  randomized,  multicenter,  double-blind,  parallel  group,  placebo-
controlled,  dose-ranging  trial  to  investigate  the  efficacy,  safety,  tolerability,  pharmacokinetics  and  pharmacodynamics  of
multiple doses (20 mg and 50 mg twice daily) of zunsemetinib in combination with methotrexate in subjects with moderate
to severe rheumatoid arthritis (ATI-450-RA-202). This trial consists of a 12-week treatment period and a 30-day follow-up
period,  and  seeks  to  enroll  approximately  240  subjects  in  the  United  States  and  in  multiple  countries  in  Europe.  The
primary endpoint is the proportion of subjects achieving ACR20 at week 12. We expect topline data in the second half of
2023.

Moderate to Severe Hidradenitis Suppurativa

In  December  2021,  we  initiated  a  Phase  2a,  randomized,  multicenter,  double-blind,  placebo-controlled  trial  to
investigate the efficacy, safety, tolerability, pharmacokinetics and pharmacodynamics of zunsemetinib (50 mg twice daily)
in subjects with moderate to severe hidradenitis suppurativa (ATI-450-HS-201). This trial consists of a 12-week treatment
period  and  a  30-day  follow-up  period.  The  trial  has  completed  enrollment  with  95  subjects  randomized  in  the  United
States. The primary endpoint is the change in inflammatory nodule and abscess count at week 12. We expect topline data in
March of 2023.

Moderate to Severe Psoriatic Arthritis

In  June  2022,  we  initiated  a  Phase  2a,  randomized,  multicenter,  double-blind,  placebo-controlled  trial  to
investigate the efficacy, safety, tolerability, pharmacokinetics and pharmacodynamics of zunsemetinib (50 mg twice daily)
in subjects with moderate to severe psoriatic arthritis (ATI-450-PsA-201). This trial consists of a 12-week treatment period
and  a  30-day  follow-up  period,  and  seeks  to  enroll  approximately  70  subjects  in  the  United  States  and  in  Poland.  The
primary endpoint is the proportion of subjects achieving ACR20 at week 12.  We expect topline data by the end of 2023.

ATI-1777, an Investigational Topical “Soft” JAK 1/3 Inhibitor

We  are  developing  ATI-1777,  an  investigational  topical  “soft”  JAK  1/3  inhibitor,  as  a  potential  treatment  for
moderate to severe atopic dermatitis. “Soft” JAK inhibitors are designed to be topically applied and active in the skin, but
rapidly metabolized and inactivated when they enter the bloodstream, which may result in low systemic exposure.

In  October  2020,  we  initiated  a  Phase  2a,  multicenter,  randomized,  double-blind,  vehicle-controlled,  parallel-
group  clinical  trial  to  determine  the  efficacy,  safety,  tolerability  and  pharmacokinetics  of  ATI-1777  in  subjects  with
moderate to severe atopic dermatitis (ATI-1777-AD-201). In the trial, which consisted of a 4-week treatment period and a
2-week follow-up period during which no treatment was given, 50 subjects with moderate to severe atopic dermatitis were
randomized in a 1:1 ratio into one of two arms: ATI-1777 topical solution 2.0% w/w or vehicle applied twice daily. In June
2021,  we  announced  that  the  trial  achieved  its  primary  endpoint,  which  was  the  percent  change  from  baseline  in  the
modified  Eczema  Area  and  Severity  Index,  or  mEASI,  score  at  week  4,  with  a  high  degree  of  statistical  significance
(p<0.001)  (one-sided  p-value),  which  corresponded  to  a  74.4%  reduction  in  mEASI  score  from  baseline  at  week  4  in
subjects applying ATI-1777 compared to a 41.4% reduction in subjects applying vehicle. The final data was based on the
full analysis set, or FAS, which was comprised of 48 subjects randomized and documented to have received at least one
dose of trial medication. Positive trends in favor of ATI-1777 were observed in key secondary efficacy endpoints, such as
improvement in itch, percent of mEASI-50 responders, investigator’s global assessment responder analysis, and reduction
in body surface area impacted by disease. In addition, the FAS analysis also showed positive trends in favor of ATI-1777 in
percent of mEASI-75 responders (65.2% for ATI-1777 compared to 24.0% for vehicle) and mEASI-90 responders (30.4%
for  ATI-1777  compared  to  20.0%  for  vehicle).  These  secondary  efficacy  endpoints  were  not  powered  for  statistical
significance.  Based  on  an  analysis  of  pharmacokinetic  plasma  samples  in  the  ATI-1777  arm  at  multiple  timepoints,
minimal systemic exposure was observed, which supports a “soft” topical JAK inhibitor approach. ATI-1777 was generally
well tolerated. No serious adverse events were reported. The most common adverse events (reported in at least 2 subjects
in the trial) were increased blood CPK levels and headache in subjects in the ATI-1777 arm and UTI (one in each of the
ATI-1777  and  the  vehicle  arm);  none  of  these  adverse  events  in  the  ATI-1777  arm  were  determined  by  the  clinical  trial
investigators to be related to ATI-1777. One treatment-related adverse event, application site pruritus, was reported in one
subject in the ATI-1777 arm.

In May 2022, we initiated a Phase 2b, multicenter, randomized, double-blind, vehicle-controlled, parallel-group
trial to determine the efficacy, safety, tolerability and pharmacokinetics of ATI-1777 in subjects with moderate to severe
atopic dermatitis (ATI-1777-AD-202). In this trial, we are exploring multiple concentrations of twice daily treatment with
ATI-1777  and  a  single  concentration  of  once  daily  treatment  with  ATI-1777,  in  patients  12  years  and  older.  This  trial
consists of a 4-week treatment period and a 2-week follow-up period, and seeks to enroll approximately 240 subjects in the
United States. The primary endpoint is the percentage change from baseline in EASI score at week 4. We expect topline
data mid-2023.

ATI-2138, an Investigational Oral Covalent ITK/JAK3 Inhibitor

We are developing ATI-2138, an investigational oral covalent ITK/JAK3 inhibitor, as a potential treatment for T
cell-mediated autoimmune diseases.  The ITK/JAK3 compound interrupts T cell signaling through the combined inhibition
of ITK/JAK3 pathways in lymphocytes. We have selected ulcerative colitis as the intended first clinical development target
for ATI-2138. We are also exploring additional indications that are relevant to the mechanism of action.

In October 2021, we submitted an Investigational New Drug application, or IND, for ATI-2138 for the treatment

of psoriasis. The IND was allowed by the U.S. Food and Drug Administration, or FDA, in November 2021.

Table of Contents

In December 2021, we initiated a Phase 1 randomized, observer-blind, placebo-controlled, single ascending dose
(SAD) trial to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of ATI-2138 in healthy subjects
(ATI-2138-PKPD-101).  In  this  trial,  64  male  and  female  healthy  volunteer  subjects  were  randomized  in  a  3:1  ratio  into
seven doses in eight cohorts.  Each cohort consisted of eight randomized subjects, with six receiving ATI-2138 and two
receiving placebo. Single dose levels were 1 mg, 3 mg, 5 mg, 15 mg, 25 mg, 50 mg and 80 mg. Data from this trial showed
that  ATI-2138  was  generally  well  tolerated  at  all  doses  tested  in  the  trial.  No  serious  adverse  events  or  severe  adverse
events were reported. The most common adverse events in subjects treated with ATI-2138, headache (four subjects) and
lightheadedness  (two  subjects),  were  mild  and  transient.  ATI-2138  demonstrated  linear  pharmacokinetic  data  and
absorption with a favorable pharmacokinetic profile up to the 80 mg single dose. The terminal half-life ranged from 1.5 to
2.5  hours.  In  addition,  no  significant  food  effect  at  the  15  mg  dose  (fasted  versus  fed)  was  observed,  and  similar
pharmacokinetic data was observed with the capsule versus tablet formulation at the 25 mg dose. We also observed dose-
dependent inhibition of both ITK and JAK3 exploratory pharmacodynamic biomarkers, and near complete inhibition of the
dual ITK and JAK3-stimulated interferon production at the 15 mg through 80 mg doses.

In October 2022, we submitted a new IND for ATI-2138 for the treatment of ulcerative colitis, which was allowed
in  November  2022.  In  December  2022,  we  initiated  a  Phase  1  placebo-controlled,  randomized,  multiple  ascending  dose
(MAD)  trial  to  investigate  the  safety,  tolerability,  pharmacokinetics  and  pharmacodynamics  of  ATI-2138  in  healthy
volunteers (ATI-2138-PKDP-102). This trial seeks to enroll approximately 60 healthy volunteers in the United States. We
expect topline data in the second half of 2023.

Preclinical Programs

ATI-2231, an Investigational Oral MK2 Inhibitor

We are exploring the use of ATI-2231, an investigational oral MK2 inhibitor designed to have a long half-life, as a
potential treatment for pancreatic cancer and metastatic breast cancer as well as in preventing bone loss in patients with
metastatic breast cancer. We expect clinical development activities to be initiated in 2023, which we expect to advance as a
collaboration with an academic third party.

Discovery Programs

We  are  developing  oral  gut-biased  JAK  inhibitors  with  limited  systemic  exposure  as  potential  treatments  for
inflammatory bowel disease. In addition, we are engaged in research to identify brain penetrant kinase inhibitor candidates
as potential treatments for neurodegenerative diseases.

Manufacturing and Supply

We  do  not  have  any  manufacturing  facilities.    We  rely  on  third  parties  for  the  manufacture  of  preclinical  and

clinical supplies for our drug candidates.

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 drug candidates, if approved, will compete with existing treatments and new treatments
that may become available in the future.

With  respect  to  zunsemetinib  as  a  potential  treatment  for  immuno-inflammatory  diseases  such  as  rheumatoid
arthritis,  hidradenitis  suppurativa  and  psoriatic  arthritis,  there  are  several  different  types  of  therapies  in  the  market.
Medications  for  the  treatment  of  rheumatoid  arthritis  and  psoriatic  arthritis  currently  fall  into  two  categories:  drugs  that
ease symptoms such as nonsteroidal anti-inflammatory drugs and drugs that slow disease activity. Drugs that slow disease
activity  include  corticosteroids  and  disease-modifying  anti-rheumatic  drugs,  or  DMARDs.  DMARDs  include  (i)
conventional synthetic DMARDs, such as methotrexate, sulfasalazine, leflunomide and hydroxychloroquine,  (ii)  biologic
DMARDs  (monoclonal  antibodies  which  inhibit  targets  such  as  TNFα,  IL1β,  IL6,  IL17  and  costimulatory  signaling
mechanisms), and (iii) targeted synthetic DMARDs such as JAK inhibitors. Hidradenitis suppurativa is currently treated

with antibiotics, corticosteroids and surgery, as well as anti-TNF therapy. Drugs for the treatment of immuno-inflammatory
diseases  such  as  rheumatoid  arthritis,  hidradenitis  suppurativa  and  psoriatic  arthritis,    are  produced  and  sold,  or  are
approved for marketing, by large pharmaceutical companies, including AbbVie, Amgen, Bristol Myers Squibb, Eli Lilly,
Johnson & Johnson, Pfizer, Novartis, UCB, Regeneron Pharmaceuticals, and Roche. In addition, we are aware of a number
of  companies  developing  and  conducting  clinical  trials  for  investigational  drug  candidates,  including  biosimilars,  that,  if
approved, could compete with zunsemetinib, if approved, for the treatment of immuno-inflammatory diseases.

With  respect  to  ATI-1777  as  a  potential  treatment  for  moderate  to  severe  atopic  dermatitis,  there  are  several
different types of therapies in the atopic dermatitis market, such as biologics, oral and topical corticosteroids, injectable and
oral  methotrexate  products,  oral  and  topical  calcineurin  inhibitors,  oral  mycophenolate  products,  other  JAK  inhibitors,
other oral antibiotics and antihistamines and phototherapy. There are also several prescription, non-prescription and over-
the-counter, or OTC, topical products, including PDE4 inhibitors, utilized to treat atopic dermatitis. These types of drugs
are produced and sold, or are approved for marketing, by large pharmaceutical companies, including AbbVie, Incyte, LEO
Pharma  A/S,  Pfizer,  and  Sanofi  and  Regeneron  Pharmaceuticals.  In  addition,  we  are  aware  of  a  number  of  companies
including large pharmaceutical companies, such as Eli Lilly, Novartis, LEO Pharma A/S, Pfizer, and Dermavant Sciences
developing and conducting clinical trials for investigational drug candidates, that, if approved, could compete with ATI-
1777, if approved, for the treatment of atopic dermatitis.

The  commercial  opportunity  for  our  drug  candidates,  if  approved,  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 any drug we may develop. Our competitors also may obtain FDA or other regulatory
approval for their drug candidates more rapidly than our potential third-party partners may obtain approval for our drug
candidates, which could result in our competitors establishing a strong market position before our drug candidates 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,  and  preclinical  and
clinical development 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 subject registration for clinical trials, as well as in acquiring technologies
complementary to, or that may be necessary for, our development programs.

Intellectual Property

Our  success  depends  in  large  part  upon  our  ability  to  obtain  and  maintain  proprietary  protection  for  our  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,  evaluating  and
taking  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 our MK2 signaling pathway inhibitor development program, we own numerous issued patents and
pending applications to novel MK2 pathway inhibitors, including our lead candidate zunsemetinib, and various methods of
use that expire, or would expire, between 2031 and 2041, subject to any applicable patent term adjustment or extension that
may be available in a particular country.  For example, we own two issued U.S. patents and issued patents and pending
applications in the European Union and other foreign countries directed to zunsemetinib and analogs thereof and certain
methods of using the same.  The U.S. patents expire in 2034 and any claims that may issue from the pending applications
expire in 2034, subject to any applicable adjustment or extension. Further, we own numerous pending patent applications in
the  U.S.,  European  Union  and  other  foreign  countries  directed  to  certain  methods  of  using  zunsemetinib,  methods  of
manufacturing zunsemetinib and crystal forms of zunsemetinib, which, if issued, would each expire in 2041, subject to any
applicable  adjustment  or  extension.  We  also  own  pending  patent  applications  in  the  U.S.,  European  Union  and  other
foreign  countries  directed  to  ATI-2231,  and  methods  of  use,  which,  if  issued,  would  expire  in  2040,  subject  to  any
applicable adjustment or extension.

With  respect  to  our  “soft”  JAK  inhibitor  development  program,  we  own  one  issued  U.S.  patent  and  numerous
pending  applications  in  the  U.S.  and  foreign  countries  to  novel  “soft”  JAK  inhibitors  and  various  methods  of  use  that
expire, or would expire, between 2038 and 2042, subject to any applicable patent term adjustment or extension that may be
available in a particular country.  For example, we own one U.S. patent and pending applications in the U.S., European
Union  and  other  foreign  countries  directed  to  various  novel  inhibitors  of  JAK1  and/or  JAK3,  including  ATI-1777,  and
methods of using the same, which, if issued, would expire in 2038, subject to any applicable adjustment or extension. We
also own PCT applications directed to crystal forms of ATI-1777 and directed to methods of using ATI-1777 and topical
formulations,  which,  if  issued,  would  expire  in  2041  and  2042,  respectively,  subject  to  any  applicable  adjustment  or
extension.

With  respect  to  our  ITK  inhibitor  development  program,  we  own  numerous  issued  U.S.  patents  and  pending
applications in the U.S. and foreign countries directed to novel inhibitors of ITK and methods of use that expire, or would
expire, between 2035 and 2039, subject to any applicable patent term adjustment or extension that may be available in a
particular  country.  For  example,  we  own  one  U.S.  patent  and  pending  U.S.,  European  Union  and  other  foreign  country
applications directed to ATI-2138 and analogs thereof and methods of using the same, which, if issued, would expire in
2039, subject to any applicable adjustment or extension.

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 use other forms of protection, such as trademark, copyright, and/or 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 drug candidates, where available.

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

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 former 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.

Under the Confluence Agreement, we agreed to pay the former Confluence equity holders aggregate remaining
contingent  consideration  of  up  to  $75.0  million  based  upon  the  achievement  of  specified  regulatory  and  commercial
milestones set forth in the Confluence Agreement. In addition, we have agreed to pay the former Confluence equity holders
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 to the payments described above, if we sell, license or transfer any of the intellectual property

9

Table of Contents

acquired from Confluence pursuant to the Confluence Agreement to a third party, we will be obligated to pay the former
Confluence  equity  holders  a  portion  of  any  consideration  received  from  such  sale,  license  or  transfer  in  specified
circumstances.

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 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 drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and its
implementing  regulations.    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 would expect to seek approval through the New Drug Application, or NDA, pathway.

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 an 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

10

Table of Contents

the clinical trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated if the first
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, as well as safety reporting. An IRB for each site 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
trials  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.

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.

11

Table of Contents

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 NDA
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 filing of the NDA. After the
FDA  evaluates  the  NDA  and  conducts  inspections  of  manufacturing  facilities  where  the  drug  product  and/or  its  active
pharmaceutical ingredient 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  are  also
continuing annual user fee requirements for products, 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
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. 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.

12

Table of Contents

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. However, physicians may, in their independent medical judgment, prescribe legally available products
for off-label uses. The FDA does not regulate the behavior of physicians in their choice of treatments but the FDA does
restrict sponsor communications on the subject of off-label use.

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 drug candidates. 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

Even  if  we  obtain  FDA  approval  for  a  drug  candidate,  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  our
potential third-party partners must obtain approval of the regulators of such countries or economic areas, such as the

13

Table of Contents

European Union, before they may market any of our drug candidates 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 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  State  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, NCEs 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 an NCE, 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 any of our drug candidates for which marketing approval is obtained. Our
potential third-party partners’ arrangements with third-party payors, health care professionals and customers may expose
them 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  they  sell,  market  and  distribute  any  drug  candidates  for  which  marketing
approval is obtained. In addition, we and our potential third-party partners 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 or they conduct
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

14

Table of Contents

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
ten years in prison, and can also result in criminal fines, civil monetary 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, activities relating to the sale and marketing
of products are subject to scrutiny under this law. Penalties for 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.  

The  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  prohibits  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 a product is sold in a foreign country, the seller 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  to  the  Centers  for  Medicare  &  Medicaid  Services,  or  CMS,  for  covered
manufacturers for certain payments and other transfers of value provided to physicians (defined to include doctors, dentists,
optometrists,  podiatrists  and  chiropractors),  other  health  care  professionals  (such  as  physician  assistants  and  nurse
practitioners)  and  teaching  hospitals,  as  well  as  information  regarding  ownership  and  investment  interests  held  by
physicians  and  their  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

15

Table of Contents

location,  and/or  require  the  tracking  and  reporting  of  gifts,  compensation  and  other  remuneration  to  health  care
professionals, including physicians.

We have developed a comprehensive compliance program that establishes internal controls to facilitate adherence
to  the  rules  and  program  requirements  to  which  we  are  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 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,  imprisonment,  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 and their subcontractors that use, disclose, access,
or  otherwise  process  protected  health  information.  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 contain 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.

There have been executive branch, judicial and Congressional challenges to certain aspects of the Affordable Care
Act. While Congress has not passed comprehensive repeal legislation, several bills affecting the implementation of certain
taxes under the Affordable Care Act have been signed into law.  On June 17, 2021 the U.S. Supreme Court dismissed a
challenge  on  procedural  grounds  that  argued  the  Affordable  Care  Act  is  unconstitutional  in  its  entirety  because  the
“individual mandate” was repealed by Congress. Prior to the U.S. Supreme Court ruling, on January 28, 2021, President
Biden  issued  an  executive  order  that  initiated  a  special  enrollment  period  for  purposes  of  obtaining  health  insurance
coverage through the Affordable Care Act marketplace. The executive order also instructed certain governmental agencies

16

Table of Contents

to  review  and  reconsider  their  existing  policies  and  rules  that  limit  access  to  healthcare,  including  among  others,
reexamining  Medicaid  demonstration  projects  and  waiver  programs  that  include  work  requirements,  and  policies  that
create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the Affordable Care Act.
 Further, on August 16, 2022, President Biden signed the Inflation Reduction Act of 2022, or IRA, into law, which among
other  things,  extends  enhanced  subsidies  for  individuals  purchasing  health  insurance  coverage  in  Affordable  Care  Act
marketplaces  through  plan  year  2025.  The  IRA  also  eliminates  the  “donut  hole”  under  the  Medicare  Part  D  program
beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and through a newly established
manufacturer  discount  program.  It  is  possible  that  the  Affordable  Care  Act  will  be  subject  to  judicial  or  Congressional
challenges  in  the  future.  It  is  unclear  how  such  challenges  and  any  additional  health  care  reform  measures  of  the  Biden
administration will impact the Affordable Care Act and our business.

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 Bipartisan Budget
Act of 2018, or the BBA, and the Infrastructure Investment and Jobs Act, will stay in effect through 2031 unless additional
Congressional action is taken. Under current legislation the actual reduction in Medicare payments will vary from 1% in
2022 to up to 4% in the final fiscal year of this sequester. 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.

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.    In  July  2021,  the  Biden  administration  released  an  executive  order,  “Promoting  Competition  in  the  American
Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9,
2021, the Department of Health and Human Services, or HHS, released a Comprehensive Plan for Addressing High Drug
Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress
could  pursue  as  well  as  potential  administrative  actions  HHS  can  take  to  advance  these  principles  In  addition,  the  IRA,
among  other  things,  (1)  directs  HHS  to  negotiate  the  price  of  certain  single-source  drugs  and  biologics  covered  under
Medicare  and  (2)  imposes  rebates  under  Medicare  Part  B  and  Medicare  Part  D  to  penalize  price  increases  that  outpace
inflation. These provisions will take effect progressively starting in fiscal year 2023, although they may be subject to legal
challenges. It is unclear how the IRA will be implemented in the future, but it is likely to have a significant impact on the
pharmaceutical  industry.  Further,  the  Biden  administration  released  an  additional  executive  order  on  October  14,  2022,
directing HHS to submit a report on how the Center for Medicare and Medicaid Innovation can be further leveraged to test
new models for lowering drug costs for Medicare and Medicaid beneficiaries. It is unclear whether this executive order or
similar policy initiatives will be implemented in the future. The effect of reducing prices and reimbursement for certain of
our  drug  candidates,  if  approved,  could  significantly  impact  our  business  and  consolidated  results  of  operations.  In
addition,  the  IRA  may  meaningfully  influence  our  and  pharmaceutical  industry  business  strategies.  In  particular,  it  may
reduce  the  attractiveness  of  investment  in  small  molecule  and  biologic  innovation.  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 FDCA

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 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

18

Table of Contents

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 believe the success of our drug candidates, if approved, will depend on obtaining and maintaining coverage
and adequate reimbursement as 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  our  potential  third-party  partners  may  not  be  able  to  negotiate  or  continue  to  negotiate
reimbursement or pricing terms for our drug candidates, if approved, with third-party payors at levels that are profitable to
us,  or  at  all.  Further  coverage  policies  and  third-party  reimbursement  rates  may  change  at  any  time.  Even  if  favorable
coverage and reimbursement status is attained for one or more products which receive regulatory approval, less favorable
coverage policies and reimbursement rates may be implemented in the future.

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  our  drug  candidates,  if
approved. Our drug candidates, if approved, 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  our  potential  third-
party  partners  to  sell  our  drug  candidates,  if  approved,  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 our potential third-party partners
could receive for any of our drug candidates, if approved, 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 drug candidates could harm our business.

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
drug  candidates,  if  approved,  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 drug candidate to other
available  therapies.    Such  pharmacoeconomic  studies  can  be  costly  and  the  results  uncertain.    Our  business  could  be
harmed if reimbursement of our drug candidates, if approved, is unavailable or limited in scope or amount or if pricing is
set at unsatisfactory levels.

Employees and Human Capital Resources

As  of  December  31,  2022,  we  had  105  total  employees,  of  which  100  were  full-time  employees.  All  of  our
employees  are  located  in  the  United  States.  None  of  our  employees  are  represented  by  a  labor  union  or  covered  by  a
collective bargaining agreement. We consider our relationship with our employees to be good.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and
integrating our existing and new employees, advisors and consultants. The principal purposes of our equity incentive plans

19

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.

Summary of Risk Factors

● 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  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.

● Our  business  is  dependent  on  the  successful  development  of  our  investigational  drug  candidate,

zunsemetinib.

● We have a limited history as a clinical-stage biopharmaceutical company developing and partnering our drug
candidates,  which  may  make  it  difficult  to  evaluate  the  success  of  our  business  to  date  and  to  assess  our
future viability.

● If we are unable to successfully develop our drug candidates and to pursue strategic alternatives, including
identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval  for  and/or  commercialize  our  drug  candidates,  or  experience  significant  delays  in  doing  so,  our
business will be harmed.

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

personnel.

● We intend to pursue strategic alternatives, including identifying and consummating transactions with third-
party partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates.
If those arrangements are not successful, we may not be able to capitalize on the market potential of these
drug candidates.

● If we are unable to obtain and maintain patent protection for our 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 pursue strategic alternatives, including
identifying  and  consummating  transactions  with  potential  third-party  partners,  to  commercialize  our
technology and drug candidates may be impaired.

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

drugs before or more successfully than we do.

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.

Since inception, we have incurred significant net losses. We incurred net losses of $86.9 million and $90.9 million
for the years ended December 31, 2022 and 2021, respectively. As of December 31, 2022, we had an accumulated deficit of
$682.3 million. We have financed our operations over the last several years primarily from sales of equity securities and
incurring indebtedness in the form of loans from commercial lenders.

We have devoted substantially all of our financial resources and efforts to the development of our drug candidates,
including preclinical studies and clinical trials. 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 in the near term as we:

● pursue strategic alternatives, including identifying and seeking to consummate transactions with third-party

partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates;

● continue the clinical development of zunsemetinib as a potential treatment for moderate to severe rheumatoid

arthritis, moderate to severe hidradenitis suppurativa and moderate to severe psoriatic arthritis, ATI-1777 as

21

 
Table of Contents

a potential treatment for moderate to severe atopic dermatitis, and ATI-2138 as a potential treatment for T
cell-mediated autoimmune diseases;

● continue to develop our preclinical drug candidates, including ATI-2231;
● continue to discover and develop additional drug candidates;
● maintain, expand and protect our intellectual property portfolio; and
● incur  legal,  accounting,  investor  relations  and  other  administrative  expenses  in  operating  as  a  public

company.  

To  become  and  remain  profitable,  we  must  succeed  in  a  range  of  challenging  activities,  including  completing
preclinical testing and clinical trials of our drug candidates and pursuing strategic alternatives, including identifying and
consummating  transactions  with  third-party  partners,  for  the  further  development  and/or  commercialization  of  our  drug
candidates, as well as discovering and developing additional drug candidates. We are in the early stages of most of these
activities. We may never succeed in these activities and, even if we do, may never earn revenue from our drug candidates
that is significant enough to achieve profitability.

For  any  of  our  drug  candidates,  our  revenue  will  be  dependent,  in  part,  upon  our  ability  to  identify  and
consummate transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize
those  drug  candidates.  Further,  we  will  be  dependent  on  our  potential  third-party  partners’  ability  to  obtain  marketing
approval  and  successfully  commercialize  the  product,  upon  the  size  of  the  markets  in  the  territories  where  marketing
approval is obtained, the accepted price for the product, and the ability to obtain coverage and reimbursement, if any. If we
fail  to  identify  and  enter  into  partnerships  with  third  parties  to  further  develop,  obtain  marketing  approval  for  and/or
commercialize our drug candidates, any partnerships we enter into do not result in the successful development, marketing
approval  for  and  commercialization  of  our  drug  candidates,  the  number  of  addressable  patients  is  not  as  significant  as
estimated by our potential third-party partners, the indication approved by regulatory authorities is narrower than expected,
or  the  treatment  population  is  narrowed  by  competition,  physician  choice  or  treatment  guidelines,  we  may  not  earn
significant  revenue  from  agreements  with  potential  third-party  partners  for  such  drug  candidates,  even  if  the  drug
candidates are approved for marketing. 

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, the development of any of our drug candidates or the identification and consummation of
transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  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, 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. 

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 identify and consummate transactions with third-party partners to further develop, obtain marketing approval
for  and/or  commercialize  our  drug  candidates.  We  expect  to  incur  significant  expenses  and  operating  losses  for  the
foreseeable  future  as  we  advance  our  drug  candidates  from  discovery  through  preclinical  and  clinical  development.  In
addition, we may not be able to identify and consummate transactions with third-party partners to further develop, obtain
marketing approval for and/or commercialize our drug candidates, and our drug candidates, if approved, may not achieve
commercial success.  Furthermore, we incur and expect to continue to incur significant costs associated with operating as a
public  company,  including  legal,  accounting,  investor  relations  and  other  expenses.    We  also  expect  to  add  additional
personnel to support our operational plans and strategic direction. 

As of December 31, 2022, we had cash, cash equivalents and marketable securities of $229.8 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

22

Table of Contents

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 number and development requirements of the drug candidates that we may pursue;
● the  scope,  progress,  results  and  costs  of  preclinical  development,  laboratory  testing  and  conducting

preclinical and clinical trials for our drug candidates;

● the costs, timing and outcome of regulatory review of our drug candidates;
● the extent to which we in-license or acquire additional drug candidates and technologies;
● 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;

● the impact on the timing of our preclinical studies, on the recruitment, enrollment, conduct and timing of our

clinical trials, and on our business, due to the COVID-19 pandemic;

● our  ability  to  identify  and  consummate  transactions  with  third-party  partners  to  further  develop,  obtain

marketing approval for and/or commercialize our drug candidates; and

● our ability to earn revenue from licenses to, or partnerships or other arrangements with, third parties.

We will require additional capital to complete the clinical development of zunsemetinib, ATI-1777 and ATI-2138,
to develop our preclinical compounds and to support our discovery efforts.  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. Our ability to raise additional capital may be adversely impacted by
potential  worsening  global  economic  conditions  caused  by  a  variety  of  factors  including  geopolitical  tensions,  rising
interest  rates  and  inflationary  pressures.  If  we  are  unable  to  raise  sufficient  additional  capital  or  generate  revenue  from
transactions with potential third-party partners for the development and/or commercialization of our drug candidates, we
could be forced to curtail our planned operations.

Our business is dependent on the successful development of our drug candidate, zunsemetinib.

Our pipeline includes zunsemetinib, our investigational oral, novel, selective MK2 inhibitor compound, which we
are  developing  as  a  potential  treatment  for  moderate  to  severe  rheumatoid  arthritis,  moderate  to  severe  hidradenitis
suppurativa  and  moderate  to  severe  psoriatic  arthritis.  The  success  of  our  business  will  significantly  depend  on  our
successful development of and/or our ability to pursue strategic alternatives for, including identifying and consummating
transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize,
zunsemetinib.

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

relinquish rights to our technologies, intellectual property, potential future revenue streams or drug candidates.

Until  such  time,  if  ever,  as  we  can  earn  substantial  revenue,  we  expect  to  finance  our  cash  needs  through  a
combination  of  equity  offerings,  debt  financings  and  license  and  partnership  agreements.  To  the  extent  that  we  raise
additional capital through the sale of equity securities or convertible debt securities, our stockholders’ ownership interest
will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights
of holders of our common stock. 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  partnerships,  strategic  alliances  or  marketing,  distribution  or  licensing
arrangements  with  potential  third-party  partners,  we  may  be  required  to  relinquish  valuable  rights  to  our  technologies,
intellectual  property,  potential  future  revenue  streams,  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 efforts or grant
rights to third parties to develop technologies, intellectual property, or drug candidates that we would otherwise prefer to
develop ourselves.

23

Table of Contents

We have a limited history as a clinical-stage biopharmaceutical company developing and partnering our drug
candidates, which may make it difficult to evaluate the success of our business to date and to assess our future viability.

Our  operations  over  the  last  several  years  have  been  largely  focused  on  undertaking  preclinical  studies  and
conducting  clinical  trials,  drug  discovery,  acquiring  new  drug  candidates  and  related  intellectual  property,  and  raising
capital.  We  have  had  limited  time  to  demonstrate  our  ability  to  successfully  develop,  manufacture  and  identify  and
consummate transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize
our drug candidates. Consequently, any predictions you make about our future success or viability may not be as accurate
as they could be if we had a longer history of being a clinical-stage biopharmaceutical company focused on developing and
partnering  drugs.  We  may  also  encounter  unforeseen  expenses,  difficulties,  complications,  delays  and  other  known  or
unknown factors in achieving our business objectives.

Our  business  could  be  adversely  affected  by  the  evolving  and  ongoing  impact  of  the  COVID-19  global
pandemic  in  regions  where  we  or  third  parties  on  which  we  rely  have  manufacturing  facilities,  clinical  trial  sites  or
other business operations.

The impact of the global COVID-19 pandemic continues to evolve. Clinical site initiation, patient enrollment and
recruitment and the supply of materials for our drug candidates may be adversely affected due to the COVD-19 pandemic,
including as a result of staffing shortages and COVID-19 infections. Some subjects may not be able to comply with clinical
trial protocols if quarantines impede patient movement.

The extent to which the COVID-19 pandemic or a similar health pandemic or epidemic impacts our business, our
preclinical  and  clinical  development  and  our  regulatory  efforts  will  depend  on  future  developments  that  are  highly
uncertain  and  cannot  be  predicted.  Accordingly,  we  do  not  yet  know  the  full  extent  of  the  impacts  on  our  business,  our
preclinical  and  clinical  development  and  regulatory  activities,  healthcare  systems  or  the  global  economy  as  a  whole.
  However,  these  impacts  could  adversely  affect  our  business,  financial  condition,  results  of  operations  and  growth
prospects.

In  addition,  to  the  extent  the  ongoing  COVID-19  pandemic  adversely  affects  our  business  and  results  of

operations, it may also have the effect of heightening many of the other risks and uncertainties described herein.

Risks Related to the Development and Potential Commercialization of Our Drug Candidates

If  we  are  unable  to  successfully  develop  our  drug  candidates  and  to  pursue  strategic  alternatives,  including
identifying and consummating transactions with third-party partners, to further develop, obtain marketing approval for
and/or 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  earn  substantial  revenue  from  our  drug  candidates  will  depend
heavily  on  our  ability  to  successfully  develop  and  pursue  strategic  alternatives,  including  identifying  and  consummating
transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize these drug
candidates. The success of any drug candidates that we develop, including zunsemetinib, will depend on several factors,
including:

● successful completion of preclinical studies and our clinical trials;
● successful development of manufacturing processes;
● receipt of timely approvals from applicable regulatory authorities;
● the  identification  and  consummation  of  transactions  with  third-party  partners  to  further  develop,  obtain

marketing approval for and/or commercialize our drug candidates;

● the commercial launch of our drug candidates, if approved, by a potential third-party partner;
● our  potential  third-party  partners’  ability  to  achieve  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  potential  third-party  partners’  ability  to  achieve  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;

24

Table of Contents

● 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 the intellectual property portfolio;

● maintaining  compliance  with  regulatory  requirements,  including  current  good  manufacturing  practices,  or

cGMPs;

● our potential third-party partners’ ability to compete effectively with other treatment procedures; and
● our potential third-party partners’ ability to maintain a continued acceptable safety, tolerability and efficacy

profile of our drug candidates following marketing approval.

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. Following submission, the NDA for any drug candidate may not be accepted for substantive review, or
even  if  it  is  accepted  for  substantive  review  the  FDA  or  other  comparable  foreign  regulatory  authorities  may  require
additional  studies  or  clinical  trials,  additional  data,  or  additional  manufacturing  steps,  or  require  other  conditions  before
they  will  reconsider  or  approve  the  application,  which  could  increase  costs  and  cause  delays  in  the  marketing  approval
process  and  which  may  require  the  expenditure  of  additional  resources.  These  delays  would  also  impact  our  ability  to
identify  and  consummate  transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or
commercialize  our  drug  candidates.  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. 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 pursue strategic alternatives, including identifying and consummating transactions with third-party partners, to
further develop, obtain marketing approval for and/or 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 of and pursue
strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further
develop, obtain marketing approval for and/or commercialize 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.

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 pursue strategic alternatives, including identifying and consummating transactions with third-party partners,
to further develop, obtain marketing approval for and/or commercialize our drug candidates, including:

● regulators or IRBs 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;

25

Table of Contents

● 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;

● the COVID-19 pandemic may impact the recruitment, enrollment, conduct and timing of our clinical trials;
● our drug candidates may have undesirable side effects or other unexpected characteristics, causing us or our

investigators, regulators or IRBs 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  IRBs  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 IRBs of the institutions
in which such trials are being conducted, by a 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, our costs
will  increase,  our  drug  candidate  development  process  will  be  slowed,  the  commercial  prospects  of  our  drug  candidates
will be harmed, and our ability to pursue strategic alternatives, including identifying and consummating transactions with
third-party partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates will be
delayed.  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 not be able to pursue strategic alternatives, including identifying and consummating transactions
with third-party partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates, and
our potential third-party partners 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. 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  our  potential
third-party partners may have the exclusive right to commercialize our drug candidates or allow competitors to bring drugs
to  market  before  such  third-party  partners  do,  which  would  impact  our  ability  to  successfully  identify  and  consummate
transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug
candidates.

26

If  we  experience  delays  or  difficulties  in  the  enrollment  of  subjects  in  clinical  trials,  our  ability  to  pursue
strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further
develop, obtain marketing approval for and/or commercialize our drug candidates 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, including as a result of factors beyond our control, such as the COVID-19 pandemic. 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 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 trial
sites  to  ensure  the  proper  and  timely  conduct  of  our  clinical  trials  and  we  will  have  limited  influence  over  their
performance. Any delays in completing clinical trials would delay or prevent our ability to pursue strategic alternatives,
including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval for and/or commercialize our drug candidates.

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 increase our
costs or necessitate the abandonment or limitation of the development of our drug candidates or prevent or delay our
ability to pursue strategic alternatives, including identifying and consummating transactions with third-party partners,
to further develop, obtain marketing approval for and/or commercialize our drug candidates.

If our drug candidates are associated with side effects in clinical trials or have characteristics that are unexpected,
our costs could increase or 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 IRB 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.

Before  any  potential  third-party  partners  can  obtain  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.

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

significant negative consequences could result, including:

● we may need to abandon the development or limit the further development of our drug candidates, including

in various populations and for certain indications;  

● regulatory authorities may withdraw approval to market such product;
● regulatory authorities may require additional warnings on the labels;

27

Table of Contents

● a medication guide outlining the risks of such side effects for distribution to patients may be required;
● we could be sued and held liable for harm caused to patients;
● our reputation and physician or patient acceptance of our drug candidates, if approved, may suffer; and
● our ability to pursue strategic alternatives, including identifying and consummating transactions with third-
party partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates
would be harmed.

Any  of  these  events  could  prevent  us  from  pursuing  strategic  alternatives,  including  identifying  and
consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or
commercialize the particular drug candidate and could significantly harm our business, results of operations and prospects.

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

From time to time, we may publicly disclose interim, topline or preliminary data from our clinical trials, which are
based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to
change  following  a  full  analysis  of  all  data  related  to  the  particular  trial.  We  also  make  assumptions,  estimations,
calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully
and carefully evaluate all data. In addition, we may report preliminary analyses of only certain endpoints rather than all
endpoints. As a result, the interim, topline or preliminary results that we report may differ from future results of the same
trials, or different conclusions or considerations may qualify such results, once additional data have been received and fully
evaluated.  Topline  data  also  remain  subject  to  audit  and  verification  procedures  that  may  result  in  the  final  data  being
materially different from the preliminary data we previously published. As a result, interim, topline and preliminary data
should be viewed with caution until the final data are available. We may also disclose interim data from our clinical trials.
Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may
materially change as subject enrollment continues and more subject data become available. Adverse differences between
interim, topline or preliminary data and final data could significantly harm our reputation and business prospects. Further,
disclosure of interim, topline or preliminary data by us or by our competitors could result in volatility in the price of our
common stock.

Further,  others,  including  regulatory  agencies,  may  not  accept  or  agree  with  our  assumptions,  estimates,
calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the
potential  of  the  particular  program,  the  likelihood  of  marketing  approval  or  commercialization  of  the  particular  drug
candidate, any approved product, and our company in general. In addition, the information we choose to publicly disclose
regarding a particular study or clinical trial is derived from information that is typically extensive, and you or others may
not agree with what we determine is material or otherwise appropriate information to include in our disclosure, and any
information  we  determine  not  to  disclose  may  ultimately  be  deemed  significant  with  respect  to  future  decisions,
conclusions, views, activities or otherwise regarding a particular program, drug candidate or our business.

If  the  interim,  topline  or  preliminary  data  that  we  report  differ  from  actual  results,  or  if  others,  including
regulatory  authorities,  disagree  with  the  conclusions  reached,  our  ability  to  pursue  strategic  alternatives,  including
identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for
and/or commercialize our drug candidates may be harmed, which could harm our business, operating results, prospects or
financial condition.

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 pursue strategic alternatives, including identifying

28

Table of Contents

and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or
commercialize our drug candidates.

We currently conduct and may in the future conduct clinical trials for our drug candidates outside the United

States. The FDA, EMA or comparable foreign regulatory authorities may not accept data from such trials.

We  currently  conduct  and  may  in  the  future  conduct  clinical  trials  for  our  drug  candidates  outside  the  United
States. The acceptance of trial data from clinical trials conducted outside the United States or another jurisdiction by the
FDA or comparable foreign regulatory authorities may be subject to certain conditions or may not be accepted at all. Such
foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There
can  be  no  assurance  that  the  FDA,  EMA  or  any  comparable  foreign  regulatory  authority  will  accept  data  from  trials
conducted  outside  of  the  United  States  or  the  applicable  jurisdiction.  If  the  FDA,  EMA  or  any  comparable  regulatory
authority  does  not  accept  such  data,  it  would  result  in  the  need  for  additional  trials,  which  would  be  costly  and  time-
consuming and delay aspects of our business plan, and which may result in our drug candidates not receiving approval or
clearance for commercialization in the applicable jurisdiction.

In addition, any escalation of political tensions, economic instability, military activity or civil hostilities outside
the United States could disrupt our ability to conduct trials outside of the United States, or delay or adversely affect the
timeliness of such trials. This could result in the need for alternative trial sites, which could be costly and time-consuming
and delay the clinical development of our drug candidates.

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

or acquiring additional drug candidates.

A key element of our strategy is to build and expand our pipeline of drug candidates. To build our pipeline, we
may seek to in-license or acquire additional drug candidates, in addition to our in-house capabilities. 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  develop,  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.

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
zunsemetinib  as  a  potential  treatment  for  moderate  to  severe  rheumatoid  arthritis,  moderate  to  severe  hidradenitis
suppurativa  and  moderate  to  severe  psoriatic  arthritis,  ATI-1777  as  a  potential  treatment  for  moderate  to  severe  atopic
dermatitis,  ATI-2138  as  a  potential  treatment  for  T  cell-mediated  autoimmune  diseases  and  ATI-2231  as  a  potential
treatment for pancreatic cancer and metastatic breast cancer as well as in preventing bone loss in patients with metastatic
breast  cancer.    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 partnerships, licensing or other arrangements in cases in which it would have been
more advantageous for us to retain sole development and commercialization rights to such drug candidate.

For any of our drug candidates that receive marketing approval, our potential third-party partners 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.

For any of our drug candidates that receive marketing approval, our potential third-party partners may fail to gain
sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. If such third-
party partners fail to obtain an adequate level of acceptance for our drug candidates, we may not earn significant revenue

29

Table of Contents

and we may not become profitable. The degree of market acceptance of any drug candidate, if approved, will depend on a
number of factors, including:

● the efficacy, safety and potential advantages compared to alternative treatments;
● our potential third-party partners’ ability to offer the 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;

● the ability of our potential third-party partners to retain a sales force;
● the strength of our potential third-party partners’ marketing and distribution support;
● the availability of third-party payor coverage and adequate reimbursement or the willingness of patients to

pay for these products;

● the prevalence and severity of any side effects; and
● any restrictions on the use of our products together with other medications.

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  will  face  competition  with
respect to any drug candidates that we may seek to develop or through our potential third-party partners, 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  zunsemetinib  as  a  potential  treatment  for  immuno-inflammatory  diseases  such  as  rheumatoid
arthritis,  hidradenitis  suppurativa  and  psoriatic  arthritis,  there  are  several  different  types  of  therapies  in  the  market.
Medications  for  the  treatment  of  rheumatoid  arthritis  and  psoriatic  arthritis  currently  fall  into  two  categories:  drugs  that
ease symptoms such as nonsteroidal anti-inflammatory drugs and drugs that slow disease activity. Drugs that slow disease
activity  include  corticosteroids  and  DMARDs.  DMARDs  include  (i)  conventional  synthetic  DMARDs,  such  as
methotrexate,  sulfasalazine,  leflunomide  and  hydroxychloroquine,  (ii)  biologic  DMARDs  (monoclonal  antibodies  which
inhibit  targets  such  as  TNFα,  IL1β,  IL6,  IL17  and  costimulatory  signaling  mechanisms),  and  (iii)  targeted  synthetic
DMARDs such as JAK inhibitors. Hidradenitis suppurativa is currently treated with antibiotics, corticosteroids and surgery,
as  well  as  anti-TNF  therapy.  Drugs  for  the  treatment  of  immuno-inflammatory  diseases  such  as  rheumatoid  arthritis,
hidradenitis  suppurativa  and  psoriatic  arthritis  are  produced  and  sold,  or  are  approved  for  marketing,  by  large
pharmaceutical  companies,  including  AbbVie,  Amgen,  Bristol  Myers  Squibb,  Eli  Lilly,  Johnson  &  Johnson,  Pfizer,
Novartis, UCB, Regeneron Pharmaceuticals,  and Roche. In addition, we are aware of a number of companies developing
and conducting clinical trials for investigational drug candidates, including biosimilars, that, if approved, could compete
with zunsemetinib, if approved, for the treatment of immuno-inflammatory diseases.

With  respect  to  ATI-1777  as  a  potential  treatment  for  moderate  to  severe  atopic  dermatitis,  there  are  several
different types of therapies in the atopic dermatitis market, such as biologics, oral and topical corticosteroids, injectable and
oral  methotrexate  products,  oral  and  topical  calcineurin  inhibitors,  oral  mycophenolate  products,  other  JAK  inhibitors,
other oral antibiotics and antihistamines and phototherapy. There are also several prescription, non-prescription and OTC
topical products, including PDE4 inhibitors, utilized to treat atopic dermatitis. These types of drugs are produced and sold,
or  are  approved  for  marketing,  by  large  pharmaceutical  companies,  including  AbbVie,  Incyte,  LEO  Pharma  A/S,  Pfizer,
and  Sanofi  and  Regeneron  Pharmaceuticals.  In  addition,  we  are  aware  of  a  number  of  companies  including  large
pharmaceutical companies, such as Eli Lilly, Novartis, LEO Pharma A/S, Pfizer, and Dermavant Sciences developing and
conducting clinical trials for investigational drug candidates, that, if approved, could compete with ATI-1777, if approved,
for the treatment of atopic dermatitis.

The  commercial  opportunity  for  our  drug  candidates,  if  approved,  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  a  drug  that  we  may  develop.  Our  competitors  also  may  obtain  FDA  or  other
regulatory approval for their drugs more rapidly than our potential third-party partners’ may obtain approval for our drug
candidates, which could result in our competitors establishing a strong market position before our drug candidates are able
to enter the market.

30

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,  and  preclinical  and
clinical development 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 development programs.

The  success  of  our  drug  candidates,  if  approved,  will  depend  significantly  on  coverage  and  adequate

reimbursement or the willingness of patients to pay for these products.

We believe the success of our drug candidates, if approved, will depend on obtaining and maintaining coverage
and adequate reimbursement as 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 these 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  our  potential  third-party  partners  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. Further,
coverage  policies  and  third-party  reimbursement  rates  may  change  at  any  time.  Even  if  favorable  coverage  and
reimbursement  status  is  attained  for  one  or  more  products  which  receive  regulatory  approval,  less  favorable  coverage
policies and reimbursement rates may be implemented in the future.  

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  our  drug  candidates,  if
approved. Our drug candidates, if approved, 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  our  potential  third-
party  partners  to  sell  our  drug  candidates,  if  approved,  on  a  competitive  and  profitable  basis.    Our  results  of  operations
could be adversely affected by the Affordable Care Act and by other health care legislative 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 our potential third-party
partners could receive for any of our drug candidates, if approved, 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 drug candidates could harm our business.

Foreign governments also have their own healthcare 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
drug  candidates,  if  approved,  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 drug candidate to other
available  therapies.    Such  pharmacoeconomic  studies  can  be  costly  and  the  results  uncertain.    Our  business  could  be
harmed if reimbursement of our drug candidates, if approved, 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 drug candidates that we may develop and are commercialized by our potential third-
party partners or impact any commercial products that we have previously sold or are being sold by third-party partners.

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 any of our commercial products that we have previously sold or are being
sold by third-party partners. If we cannot successfully defend ourselves against claims that our commercial products that
we  have  previously  sold  or  are  being  sold  by  third-party  partners,  or  drug  candidates,  caused  injuries,  we  will  incur
substantial liabilities. Regardless of merit or eventual outcome, product liability claims may result in:

● decreased demand for any drug candidates that we may develop and, if approved, are commercialized by our

potential third-party partners;

● 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; and
● our inability to pursue strategic alternatives, including identifying and consummating transactions with third-
party partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates.

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  rely  on  third  parties  to  conduct  clinical  trials  for  our  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 identify and consummate transactions with third-party partners to further develop,
obtain marketing approval for and/or 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
earn revenue from those partnerships 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.

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

32

Table of Contents

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 or comparable foreign regulatory authorities may require us to perform additional
clinical trials before approving 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 drug 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 for our
potential third-party partners.

We also rely on other third parties to store and distribute drug supplies 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 drug candidates, if approved, producing additional losses and depriving us of potential revenue.

We  contract  with  third  parties  for  the  manufacture  and  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 our drug
candidates or such quantities at an acceptable cost, which could delay, prevent or impair our development efforts.

We do not have any manufacturing facilities. We currently rely, and expect to continue to rely, on third parties for
the  manufacture  and  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  our  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 efforts.

The  facilities  used  by  our  contract  manufacturers  to  manufacture  our  drug  candidates  must  be  approved  by  the
FDA  or  comparable  foreign  regulatory  authorities  pursuant  to  inspections  that  will  be  conducted  after  the  NDA  or
comparable  marketing  application  is  submitted  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  in  the  future,  we  may  need  to  find  alternative
manufacturing facilities, which could significantly impact our ability to develop, and identify and consummate transactions
with third-party partners to further develop, obtain marketing approval for and/or commercialize, our drug candidates.

We may be unable to establish any agreements with future third-party manufacturers or 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 for our

drug candidates; 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 drug candidates. 

33

Table of Contents

Our drug candidates 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 of our drug candidates.

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  do  not
currently  have  arrangements  in  place  for  redundant  supply  or  a  second  source  for  the  active  pharmaceutical  ingredients
and/or drug product for our drug candidates.

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  drug  candidates  may  adversely  affect  our  future
profit  margins  and  our  ability  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with
third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates  on  a
timely and competitive basis.

We  intend  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-
party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates.  If  those
arrangements are not successful, we may not be able to capitalize on the market potential of these drug candidates.

We intend to pursue strategic alternatives, including identifying and consummating transactions with third-party
partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates. Our likely partners
for  any  such  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  partners  dedicate  to  the  development  or
commercialization  of  our  drug  candidates.  Our  ability  to  earn  revenue  from  these  arrangements  will  depend  on  our
partners’ abilities to successfully perform the functions assigned to them in these arrangements.

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

● partners  have  significant  discretion  in  determining  the  efforts  and  resources  that  they  will  apply  to  these

arrangements;

● partners may not perform their obligations as expected;
● partners may not pursue development, marketing approval or 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  partners’  strategic  focus  or  available  funding,  or
external factors, such as an acquisition, that divert resources or create competing priorities;

● partners 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;

● partners  could  independently  develop,  or  develop  with  third  parties,  products  that  compete  directly  or
indirectly  with  our  drug  candidates  if  the  partners  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  our  partners  to  cease  to  devote  resources  to  the
development and/or commercialization of our drug candidates, if approved;

● a partner 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  partners,  including  disagreements  over  proprietary  rights,  contract  interpretation  or  the
preferred  course  of  development  or  commercialization,  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;

34

Table of Contents

● partners 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;

● partners may infringe the intellectual property rights of third parties, which may expose us to litigation and

potential liability; and

● partnerships may be terminated for the convenience of the partner and, if terminated, we could be required to
raise  additional  capital  to  pursue  further  development  and/or  commercialization  of  the  applicable  drug
candidates.

Partnership  agreements  may  not  lead  to  development,  marketing  approval  or  commercialization  of  drug
candidates in the most efficient manner or at all. If a present or future partner 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  partnerships,  we  may  have  to  alter  our  development  and  commercialization

plans.

Our drug development programs for our drug candidates will require substantial additional capital. We intend to
partner  with  pharmaceutical  and  biotechnology  companies  for  the  further  development  and/or  commercialization  of  our
drug candidates.

We face significant competition in seeking appropriate partners. Whether we reach a definitive agreement for a
partnership will depend, among other things, upon our assessment of the partner’s resources and expertise, the terms and
conditions of the proposed arrangement and the proposed partner’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  partner  may  also  consider  alternative  drug
candidates or technologies for similar indications that may be available to partner on and whether such a partnership could
be more attractive than the one with us for our drug candidate. Partnerships 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 partners.

We may not be able to negotiate partnerships 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, or reduce or delay its development program or one
or more of our other development programs, 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.

We  may  not  have  access  to  all  information  regarding  our  drug  candidates  that  are  subject  to  partnership
agreements.  Consequently,  our  ability  to  inform  our  stockholders  about  the  status  of  our  drug  candidates  that  are
subject to these agreements, and our ability to make business and operational decisions, may be limited.

We  may  not  have  access  to  all  information  regarding  our  drug  candidates  that  may  become  subject  to  agreements
with  partners,  including  potentially  material  information  about  clinical  trial  design,  execution  and  timing,  safety  and
efficacy,  clinical  trial  results,  regulatory  affairs,  manufacturing,  marketing,  sales  and  other  areas  known  by  our  potential
partners.  In  addition,  we  may  have  confidentiality  obligations  under  our  agreements  with  such  partners.  Therefore,  our
ability to keep our stockholders informed about the status of our drug candidates will be limited by the degree to which our
partners keep us informed and by the degree to which our partners allow us to disclose information to the public or provide
such information to the public themselves. If our partners do not timely inform us about the status of our drug candidates
that are the subject of the partnership, we may make operational and investment decisions that we would not have made
had we been fully informed, which may have an adverse impact on our business, prospects, financial condition and results
of operations.

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 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  ability  to  successfully  identify  a  potential  third-party  partner  to  commercialize  our
technology 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 drug candidates. We seek to protect our proprietary position by filing patent applications
in the United States and abroad related to our 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
drug candidates, in whole or in part, or which effectively prevent others from commercializing competitive technologies
and drug candidates. 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  other  foreign  patent  office,  or  become  involved  in  opposition,  central  revocation,  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 commercialize our technology or drug candidates and compete directly
with  us,  without  payment  to  us,  or  result  in  the  inability  of  our  potential  third-party  partners  to  manufacture  or
commercialize  our  drug  candidates  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 partnering with us to license, develop and/or commercialize our drug candidates. 

Even  if  our  patent  applications  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  our  potential  third-party  partners  or  otherwise
provide us or our potential third-party partners with any competitive advantage. Competitors may be able to circumvent our
patents by developing similar or alternative technologies or drugs in a non-infringing manner.

36

Table of Contents

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 the ability to stop others from using or commercializing similar or identical technology and drug
candidates, or limit the duration of the patent protection of our technology and drug candidates. Our issued U.S. patents
covering zunsemetinib expire in 2034. We currently do not have any patents issued directed to ATI-2231, but any claims
that may issue would expire in 2040. Our issued U.S. patent covering ATI-1777 expires in 2038. Our issued U.S. patent
directed  to  ATI-2138  expires  in  2039.  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 or our potential third-party partners 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,  or  similar  requirements  outside  of  the  United  States.
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 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  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. 

Interference or derivation 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 may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on our 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, zunsemetinib is currently covered by patents and applications in the
United  States,  European  Union  and  other  foreign  markets.  While  we  have  issued  U.S.  patents  directed  to  ATI-1777  and
ATI-2138, we do not currently have any patents for such drug candidates in the European Union or other foreign markets;
rather, we have pending applications in the European Union and other foreign markets directed to each of ATI-

37

Table of Contents

1777  and  ATI-2138.  Currently,  we  do  not  have  any  issued  patents  directed  to  ATI-2231,  but  we  have  a  pending  PCT
application.

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  ability  to  pursue  strategic  alternatives,
including  identifying  and  consummating  transactions  with  potential  third-party  partners,  to  further  develop,  obtain
marketing approval for and/or commercialize our drug candidates, and consequently 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  and/or  commercialization  of  our  drug  candidates.  It  may  be  necessary  for  us  or  our  potential  third-party
partners  to  use  the  patented  or  proprietary  technology  of  third  parties  to  further  develop  and/or  commercialize  our  drug
candidates.  If  we  or  our  potential  third-party  partners  are  not  able  to  obtain  a  license  from  these  third  parties  on
commercially reasonable terms, our business could be harmed, possibly materially, and even if we or they are able to, it
may result in the reduction of revenue we earn from such partner as a result of payment obligations to the licensor. 

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  success  depends  upon  our  ability  to  pursue  strategic  alternatives,  including  identifying  and  consummating
transactions with potential third-party partners, to develop, obtain marketing approval for and/or commercialize our drug
candidates and earn revenue from those partnerships, and for our proprietary technologies to be used 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  drug  candidates  and  technologies,  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 or our potential third-party partners are found to infringe a third party’s intellectual property rights, we or
such partners could be required to obtain a license from such third party to continue developing or commercializing our
drug candidates and technology. However, we or our potential third-party partners may not be able to obtain any required
license on commercially reasonable terms or at all. Even if we or our potential third-party partner were able to obtain a
license, it could be non-exclusive, thereby giving competitors access to the same technologies licensed to us or our partner.
Consequently,  we  or  our  potential  third-party  partner  could  be  forced,  including  by  court  order,  to  cease  developing  or
commercializing the infringing technology or drug candidate. In addition, we or our potential third-party partner could be
found liable for monetary damages, including treble damages and attorneys’ fees if we or such partner are found to have
willfully  infringed  a  patent.  A  finding  of  infringement  could  prevent  our  potential  third-party  partners  from
commercializing our drug candidates, if approved, or force such partners to cease some of their business operations. In the
event of a successful claim of infringement against us or our potential third-party partners, we or our potential third-party
partners may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, pay
royalties,  redesign  our  infringing  drug  candidate  or  obtain  one  or  more  licenses  from  third  parties,  which  may  be
impossible

38

Table of Contents

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.  We  may  not  have  sufficient  financial  or
other resources to conduct such litigation or proceedings 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 compete in the marketplace, including compromising our ability
to  raise  the  funds  necessary  to  continue  our  clinical  trials,  continue  our  internal  research  programs,  or  pursue  strategic
alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain
marketing approval for and/or 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  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

39

Table of Contents

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  any  of  our  drug  candidates  can  be

challenged by competitors.

If  any  of  our  drug  candidates  advance  through  development  or  are  approved  by  the  FDA  or  foreign  regulatory
authority, 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.  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. Litigation or other proceedings to enforce or defend intellectual property rights are
often very complex in nature, may be 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 our
drug candidates, if approved. 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, which would harm our ability to pursue strategic alternatives,
including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval for and/or commercialize our drug candidates, and earn revenue from such arrangements. In addition, any such
challenge on any divested product could harm our ability to earn revenue from the arrangements for such product. 

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

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

Our 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,  drug  candidates  and  our  target
indications.  Our issued U.S. patents covering zunsemetinib expire in 2034. We currently do not have any patents issued
directed  to  ATI-2231,  but  any  claims  that  may  issue  would  expire  in  2040.  Our  issued  U.S.  patent  covering  ATI-1777
expires in 2038. Our issued U.S. patent directed to ATI-2138 expires in 2039. 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 Drug Price Competition and Patent
Term Restoration Act of 1984, or 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.  Similar
provisions are available in certain foreign countries, such as the European Union and Japan.

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.

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 our products, services or technologies from those of

our competitors. Once we select new trademarks and apply to register them, our trademark applications may not be

40

Table of Contents

approved. Third parties may oppose or attempt to cancel our trademark applications or trademarks, or otherwise challenge
our use of the trademarks. In such an event, we may need to negotiate a settlement agreement with such third party over the
use of our trademarks, which we may not be able to do on commercially reasonable terms, if at all. In the event that our
trademarks  are  successfully  challenged,  our  products,  services  or  technologies  may  need  to  be  rebranded,  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 or trademark protection. For example,
we may elect not to seek patent protection in some jurisdictions or for some 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.

For  example,  following  the  result  of  a  referendum  in  2016,  the  United  Kingdom  left  the  European  Union  on
January  31,  2020,  commonly  referred  to  as  Brexit.  The  impact  of  the  withdrawal  of  the  United  Kingdom  from  the
European  Union  will  not  be  known  for  some  time,  which  could  lead  to  a  period  of  uncertainty  relating  to  our  ability  to
obtain and maintain patents and trademarks in the United Kingdom. In 2012, the European Patent Package, or EU Patent
Package, regulations were passed with the goal of providing for a single pan-European Unitary Patent, and a new European
Unified  Patent  Court,  or  UPC,  for  litigation  of  European  patents.  It  is  possible  that  implementation  of  the  EU  Patent
Package  will  occur  in  the  first  half  of  2023.  If  the  EU  Patent  Package  is  ratified  and  in  effect,  all  European  patents,
including those issued prior to ratification, would by default automatically fall under the jurisdiction of the UPC and allow
for  the  possibility  of  obtaining  pan-European  injunctions.  Under  the  EU  Patent  Package  as  currently  proposed,  once  the
UPC is established, patent holders are permitted to “opt out” of the UPC on a patent-by-patent basis during an initial seven
year period after the EU Patent Package is ratified. Owners of traditional European patent applications who receive notice
of grant after the EU Patent Package is ratified could either accept a Unitary Patent or validate the patent nationally and file
an  opt-out  demand.  The  EU  Patent  Package  may  increase  the  uncertainties  and  costs  surrounding  the  enforcement  or
defense of our issued European patents and pending applications. The full impact on future European patent filing strategy
and the enforcement or defense of our issued European patents in member states and/or the UPC is not known.

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:

● we, our licensors or any potential third-party partners 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 potential third-party partners 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 major commercial markets; and

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

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

If  our  potential  third-party  partners  are  not  able  to  obtain,  or  if  there  are  delays  in  obtaining,  required
regulatory approvals, our drug candidates will not be able to be commercialized, and our ability to earn revenue from
arrangements with such third-party partners 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, other regulatory agencies in the United States and similar
regulatory authorities outside the United States. Failure to obtain marketing approval for a drug candidate will prevent our
potential  third-party  partners  from  commercializing  the  drug  candidate.  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  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  potential  third-party  partners  from
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 product in this way, which could limit sales of the product. 

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  our  potential  third-party  partners  ultimately
obtain  may  be  limited  or  subject  to  restrictions  or  post-approval  commitments  that  render  the  approved  drug  not
commercially viable.

If our potential third-party partners experience delays in obtaining approval or if they fail to obtain approval of our
drug candidates, the commercial prospects for our drug candidates may be harmed and our ability to earn revenue from
arrangements with such third-party partners 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 outside the United States,
our  potential  third-party  partners  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. Our potential third-party partners 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  potential  third-party  partners’  ability  to  obtain  approval  elsewhere.  Our
potential third-party partners 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  by  our  potential  third-party  partners

internationally could harm our business.

If our drug candidates, if approved, are marketed internationally by our potential third-party partners, our potential

third-party partners would be subject to additional risks related to operating in foreign countries, 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 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 our drug candidates to foreign countries; and
● business interruptions resulting from geo-political actions, including war and terrorism.

These and other risks associated with international operations may compromise our ability to earn revenue from

arrangements with potential third-party partners for our drug candidates.

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

Any  drug  candidate  for  which  our  potential  third-party  partners  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 by our potential third-party
partners.

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  our
potential third-party partners do not market our drugs for their approved indications, they may be subject to enforcement
action for off-label marketing. Physicians, on the other hand, may prescribe products for off-label uses. Although the FDA
and other regulatory agencies do not regulate a physician’s choice of drug treatment made in the physician’s independent
medical judgment, they do restrict promotional communications from companies or their sales force with respect to off-

43

Table of Contents

label uses of products for which marketing clearance has not been issued. However, companies may share truthful and not
misleading  information  that  is  otherwise  consistent  with  the  product’s  FDA  approved  labeling.  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;
● 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. These and other risks associated with the failure by our
potential  third-party  partners  to  comply  with  regulatory  requirements  may  compromise  our  ability  to  earn  revenue  from
arrangements with such third-party partners for our drug candidates.

Our  potential  third-party  partners’  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, and any failure to comply with such laws and regulations could have a material adverse effect on
our ability to earn revenue from arrangements with such third-party partners for our drug candidates.

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 drug candidates for which marketing approval is obtained. Our
potential third-party partners’ arrangements with third-party payors, health care professionals and customers may expose
them 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  they  sell,  market  and  distribute  any  drug  candidates  for  which  marketing
approval is obtained. In addition, we and our potential third-party partners 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 or they conduct
business.  The  applicable  federal,  state  and  foreign  health  care  laws  and  regulations  that  may  affect  our  or  our  potential
third-party partners’ 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

44

Table of Contents

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;

● 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;

● federal Health Insurance Portability and Accountability Act of 1996, or 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  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  or
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
and  their  subcontractors  that  use,  disclose,  access,  or  otherwise  process  protected  health  information,  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  Centers  for  Medicare  &  Medicaid  Services,  or  CMS,  information  related  to  “payments  or  other
transfers of value” made to physicians, which is defined to include doctors, dentists, optometrists, podiatrists
and chiropractors, other health care professionals (such as physician assistants and nurse practitioners), and
teaching  hospitals,  and  for  applicable  manufacturers  to  report  annually  to  CMS  information  regarding
ownership and investment interests held by physicians and their immediate family members; and

● analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which
may apply to sales or marketing arrangements and claims involving 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  or  our  potential  third-party  partners’  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  or  our  potential  third-party  partners’  business  practices,  including  relationships  with
physicians and other health care providers, some of whom may recommend, purchase and/or prescribe our drug candidates,
if approved, 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 or our potential third-party partners’ operations are found to be in violation of any of these laws or any other
governmental  regulations  that  may  apply  to  us  or  them,  we  or  our  potential  third-party  partners  may  be  subject  to
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,

45

Table of Contents

additional reporting requirements and oversight if we or they 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  or  their
operations, which could have a material adverse effect on our ability to earn revenue from arrangements with such third-
party  partners  for  our  drug  candidates.  If  any  physician  or  other  health  care  provider  or  entity  with  whom  we  or  our
potential third-party partners expect to do business is found not to be in compliance with applicable laws, it may be subject
to significant criminal, civil or administrative sanctions, including exclusions from participation in government health care
programs, which could also materially affect our ability to earn revenue from arrangements with such third-party partners
for our drug candidates.

Recently  enacted  and  future  legislation  may  increase  the  difficulty  and  cost  for  our  potential  third-party
partners to obtain marketing approval of our drug candidates and commercialize our drug candidates, if approved, and
affect the prices our potential third-party partners 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 potential third-party partners’ ability to profitably sell
any of our drug candidates for which our potential third-party partners obtain marketing approval, and consequently affect
our ability to earn revenue from arrangements with such third-party partners for our drug candidates.

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 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 commercial products 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 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;

● requirements under the federal Open Payments program and its implementing regulations;
● a requirement to annually report drug samples that manufacturers and distributors provide to physicians; and
● the Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative

clinical effectiveness research, along with funding for such research.

There have been executive branch, judicial and Congressional challenges to certain aspects of the Affordable Care
Act. While Congress has not passed comprehensive repeal legislation, several bills affecting the implementation of certain
taxes under the Affordable Care Act have been signed into law. On June 17, 2021 the U.S. Supreme Court dismissed

46

Table of Contents

a  challenge  on  procedural  grounds  that  argued  the  Affordable  Care  Act  is  unconstitutional  in  its  entirety  because  the
“individual mandate” was repealed by Congress. Prior to the U.S. Supreme Court ruling, on January 28, 2021, President
Biden  issued  an  executive  order  that  initiated  a  special  enrollment  period  for  purposes  of  obtaining  health  insurance
coverage through the Affordable Care Act marketplace. The executive order also instructed certain governmental agencies
to  review  and  reconsider  their  existing  policies  and  rules  that  limit  access  to  healthcare,  including  among  others,
reexamining  Medicaid  demonstration  projects  and  waiver  programs  that  include  work  requirements,  and  policies  that
create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the Affordable Care Act.
Further,  on  August  16,  2022,  President  Biden  signed  the  IRA  into  law,  which  among  other  things,  extends  enhanced
subsidies  for  individuals  purchasing  health  insurance  coverage  in  Affordable  Care  Act  marketplaces  through  plan  year
2025.  The  IRA  also  eliminates  the  “donut  hole”  under  the  Medicare  Part  D  program  beginning  in  2025  by  significantly
lowering the beneficiary maximum out-of-pocket cost and through a newly established manufacturer discount program.  It
is possible that the Affordable Care Act will be subject to judicial or Congressional challenges in the future. It is unclear
how  such  challenges  and  any  additional  health  care  reform  measures  of  the  Biden  administration  will  impact  the
Affordable Care Act and 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  and  the
Infrastructure Investment and Jobs Act, will stay in effect through 2031 unless additional Congressional action is taken.
 Under current legislation the actual reduction in Medicare payments will vary from 1% in 2022 to up to 4% in the final
fiscal  year  of  this  sequester.  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 our ability
to earn revenue from arrangements with our potential third-party partners for our drug candidates.

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 our potential
third-party  partners  receive  for  any  approved  drug  candidate.  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  our  potential  third-party  partners  from  being  able  to
generate  revenue,  attain  profitability,  or  commercialize  our  drug  candidates,  if  approved,  which  in  turn  may  impact  our
ability to earn revenue from arrangements with such third-party partners for our drug candidates. Further, it is also possible
that additional governmental action is taken in response to the COVID-19 pandemic.

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.  In  July  2021,  the  Biden
administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions
aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, U.S. Department of Health and
Human  Services,  or  HHS,  released  a  Comprehensive  Plan  for  Addressing  High  Drug  Prices  that  outlines  principles  for
drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue as well as potential
administrative actions HHS can take to advance these principles. In addition, the IRA, among other things, (1) directs HHS
to negotiate the price of certain single-source drugs and biologics covered under Medicare and (2) imposes rebates under
Medicare Part B and Medicare Part D to penalize price increases that outpace inflation. These provisions will take effect
progressively starting in fiscal year 2023, although they may be subject to legal challenges. It is currently unclear how the
IRA  will  be  implemented  but  is  likely  to  have  a  significant  impact  on  the  pharmaceutical  industry.  Further,  the  Biden
administration released an additional executive order on October 14, 2022, directing HHS to submit a report on how the
Center  for  Medicare  and  Medicaid  Innovation  can  be  further  leveraged  to  test  new  models  for  lowering  drug  costs  for
Medicare  and  Medicaid  beneficiaries.  It  is  unclear  whether  this  executive  order  or  similar  policy  initiatives  will  be
implemented in the future. It is unclear whether these or similar policy initiatives will be implemented in the future. The
effect of reducing prices and reimbursement for certain of our drug candidates, if approved, could significantly impact our
business and consolidated results of operations. In addition, the IRA may meaningfully influence our and pharmaceutical
industry business strategies. In particular, it may reduce the attractiveness of investment in small molecule and biologic

47

innovation.  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 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 obtaining marketing approvals for 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  our  potential  third-party  partners  to  more  stringent  drug  labeling  and  post-marketing  testing
and other requirements. These risks may compromise our ability to earn revenue from arrangements with such third-party
partners for our drug candidates.

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

revenue.

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, our potential third-party partners 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  drug  candidates  is
unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our potential third-party partners may
not able to generate revenue, which in turn may adversely affect our ability to earn revenue from arrangements with such
third-party partners for our drug candidates. 

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

We  are  subject  to  governmental  economic  sanctions  and  export  and  import  controls  that  could  impair  our
potential  third-party  partners’  ability  to  compete  in  international  markets  or  subject  us  or  our  potential  third-party
partners to liability if we or they 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  drug  candidates,  technology  and  services  in  compliance  with
those  laws  and  regulations,  including  the  U.S.  Export  Administration  Regulations,  U.S.  Customs  regulations,  the
International Traffic in Arms Regulations, and economic embargo and trade sanction programs administered by the U.S.
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

48

Table of Contents

prevent doing any business, directly or indirectly, with countries, governments and persons targeted by U.S. sanctions and
to  ensure  that  our  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  or  our  potential  third-party  partners  export  our  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 may be time-consuming and may result in the delay or loss of sales opportunities.
Failure  to  comply  with  export  control  and  sanctions  regulations  may  expose  us  or  our  potential  third-party  partners  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 and our potential third-party partners are subject to anti-corruption and anti-money laundering laws with
respect to our and their operations and non-compliance with such laws can subject us to criminal and/or civil liability
and harm our business.

We and our potential third-party partners 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. We or our potential third-party partners may engage third-
party intermediaries in connection with the development or commercialization of our drug candidates, if approved, and to
obtain necessary permits, licenses and other regulatory approvals. We, our potential third-party partners or the 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,  and  business  development
expertise of Dr. Douglas Manion, our Chief Executive Officer and President, Kevin Balthaser, our Chief Financial Officer,
Dr. Joseph Monahan, our Chief Scientific Officer, Dr. Gail Cawkwell, our Chief Medical Officer, and James Loerop, our
Chief Business Officer, as well as the other members of our scientific and clinical teams. Although we have entered into
employment agreements with 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. Manion. 

Recruiting  and  retaining  qualified  scientific,  manufacturing  and  clinical  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  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 and
partner drug candidates. 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

49

Table of Contents

and  clinical  advisors,  to  assist  us  in  formulating  our  development  strategy.  Our  consultants  and  advisors  may  have
commitments under employment, 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. 

Our employees, independent contractors, consultants, third-party partners, 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, third-party partners, 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  by  our
potential third-party partners 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.

In addition, we have a hybrid work model of remote and in-person operations for our employees that enables us to
continue  to  develop  our  drug  candidates  and  provide  contract  research  services  to  our  clients.  The  effects  of  our  hybrid
work  model  may  negatively  impact  productivity,  disrupt  our  business  and  delay  our  preclinical  drug  development  and
clinical  trials  and  timelines.  These  and  similar,  and  perhaps  more  severe,  disruptions  in  our  operations  could  negatively
impact our business, operating results and financial condition.

Risks Related to Ownership of Our Common Stock

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

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 and/or results of any preclinical studies and 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 of any of our drug candidates to receive marketing approval;
● unanticipated serious safety concerns related to the use of any drug candidate or previously sold commercial

product;

● changes in financial estimates by us or by any securities analysts who might cover our stock;

50

Table of Contents

● 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;
● the evolution of the COVID-19 pandemic and success of mass vaccination efforts; and
● other events or factors, many of which are beyond our control.

In  the  past,  stockholders  have  initiated  class  action  lawsuits  against  us  and  other  pharmaceutical  companies
following  periods  of  volatility  in  the  market  prices  of  these  companies’  stock.  We  have  entered  into  indemnification
agreements  with  our  executive  officers  and  directors  which  provide,  among  other  things,  that  we  will  indemnify  such
officer or director, under the circumstances and to the extent provided for therein, for expenses, damages, judgments, fines
and settlements he or she may be required to pay in actions or proceedings which he or she is or may be made a party by
reason  of  his  or  her  position  as  our  director,  officer  or  other  agent,  and  otherwise  to  the  fullest  extent  permitted  under
Delaware law and our bylaws. Such additional litigation, if instituted against us, could cause us to incur substantial costs
and divert management’s attention and resources from our business.

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

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:

51

Table of Contents

● only one of our three classes of directors is elected each year;
● stockholders are not entitled to remove directors other than by a 66 2/3% 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.

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.

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.

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, 2022, we had federal and state net operating loss carryforwards, or NOLs, of $446.7 million
and  $477.9  million,  respectively,  which  will  begin  to  expire  in  2032.    Under  federal  law,  federal  NOL  carryforwards
generated  in  tax  years  beginning  after  December  31,  2017  may  be  carried  forward  indefinitely  but  may  only  be  used  to
offset 80% of our taxable income annually. It is uncertain if and to what extent various states will conform to the federal
tax law.  As of December 31, 2022, we also had federal research and development tax credit carryforwards of 15.1 million
which will begin to expire in 2032, and state research and development tax credit carryforwards of $0.1 million which will
begin  to  expire  in  2022.  We  also  have  $0.2  million  of  loss  carryforwards  in  the  United  Kingdom  which  can  be  carried
forward  indefinitely.  These  NOL  and  tax  credit  carryforwards  could  expire  unused  or  due  to  limitation  on  use  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 NOLs generated from July 13, 2012 through December
31, 2021.  Although we have experienced Section 382 ownership changes since 2012, we have concluded that we should
have sufficient ability to utilize NOLs accumulated during the periods tested.  We have not yet determined if a Section 382
ownership change has occurred after December 31, 2021.  In addition, we may experience ownership changes

52

Table of Contents

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 NOL and tax credit carryforwards is
materially limited, it might harm our future operating results by effectively increasing our future tax obligations.

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.  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.

Exclusive forum provisions in our amended and restated certificate of incorporation and amended and restated
bylaws could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors,
officers or other employees.

Our  amended  and  restated  certificate  of  incorporation  provides  that  the  Court  of  Chancery  of  the  State  of
Delaware is the exclusive forum for the following types of actions or proceedings under Delaware statutory or common
law: (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.  This  provision  would  not  apply  to  suits  brought  to  enforce  a  duty  or  liability  created  by  the  Exchange  Act.
Furthermore,  Section  22  of  the  Securities  Act  creates  concurrent  jurisdiction  for  federal  and  state  courts  over  all  such
Securities  Act  actions.  Accordingly,  both  state  and  federal  courts  have  jurisdiction  to  entertain  such  claims.  To  prevent
having  to  litigate  claims  in  multiple  jurisdictions  and  the  threat  of  inconsistent  or  contrary  rulings  by  different  courts,
among  other  considerations,  our  amended  and  restated  bylaws  provide  the  federal  district  courts  of  the  United  States  of
America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities
Act. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may
nevertheless  seek  to  bring  a  claim  in  a  venue  other  than  those  designated  in  the  exclusive  forum  provisions.  In  such
instance,  we  would  expect  to  vigorously  assert  the  validity  and  enforceability  of  the  exclusive  forum  provisions  of  our
amended  and  restated  certificate  of  incorporation  and  our  amended  and  restated  bylaws.  This  may  require  significant
additional  costs  associated  with  resolving  such  action  in  other  jurisdictions  and  there  can  be  no  assurance  that  the
provisions will be enforced by a court in those other jurisdictions.

Our  amended  and  restated  certificate  of  incorporation  and  amended  and  restated  bylaws  further  provide  any
person or entity purchasing or otherwise acquiring any interest in shares of our common stock is deemed to have notice of
and consented to the foregoing provisions. These exclusive forum provisions may limit a stockholder’s ability to bring a
claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which
may discourage lawsuits against us and our directors, officers and other employees. If a court were to find either exclusive-
forum  provision  to  be  inapplicable  or  unenforceable  in  an  action,  we  may  incur  further  significant  additional  costs
associated with resolving the dispute in other jurisdictions, all of which could seriously harm our business.

General Risk Factors

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,  supply  chain  attacks,  ransomware  attacks,
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 obtaining

53

Table of Contents

marketing approval for our drug candidates 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 by a potential third-
party partner could be delayed.

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

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  be  sustained.  If  an  active  market  for  our  common  stock  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. 

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. 

Environmental, social and governance matters may impact our business and reputation.

Increasingly,  in  addition  to  the  importance  of  their  financial  performance,  companies  are  being  judged  by  their
performance on a variety of environmental, social and governance, or ESG, matters, which are considered to contribute to
the long-term sustainability of companies’ performance.

A variety of organizations measure the performance of companies on such ESG topics, and the results of these
assessments are widely publicized. In addition, investment in funds that specialize in companies that perform well in such
assessments  are  increasingly  popular,  and  major  institutional  investors  have  publicly  emphasized  the  importance  of
such ESG measures to their investment decisions. Topics taken into account in such assessments include, among others, the
company’s efforts and impacts on climate change and human rights, ethics and compliance with law, and the role of the
company’s board of directors in supervising various sustainability issues. In addition to the topics typically considered in
such assessments, in the healthcare industry, issues of the public’s ability to access medicines are of particular importance.

In light of investors’ increased focus on ESG matters, there can be no certainty that we will manage such issues
successfully. Any failure or perceived failure by us in this regard could have a material adverse effect on our reputation and
on our business, stock price, financial condition, or results of operations, including the sustainability of our business over
time.

Unfavorable conditions, including inflationary pressure, in the global economy could limit our ability to grow

our business and negatively affect our operating results.

General  worldwide  economic  conditions  have  experienced  significant  instability  in  recent  years  including  the
recent global economic uncertainty and financial market conditions. For example, inflation rates, particularly in the United
States  and  United  Kingdom,  have  increased  recently  to  levels  not  seen  in  years,  and  increased  inflation  may  result  in
increases in our operating costs (including our labor costs), reduced liquidity and limits on our ability to access credit or
otherwise  raise  capital.  In  addition,  the  Federal  Reserve  has  raised,  and  may  again  raise,  interest  rates  in  response  to
concerns about inflation, which coupled with reduced government spending and volatility in financial markets may have
the  effect  of  further  increasing  economic  uncertainty  and  heightening  these  risks.  Additionally,  financial  markets  around
the world experienced volatility following the invasion of Ukraine by Russia in February 2022. These conditions make it
extremely difficult for us to accurately forecast and plan future business activities.

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. 

Changes in tax laws or regulations that are applied adversely to us may have a material adverse effect on our

business, cash flow, financial condition or results of operations.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time,
which could adversely affect our business operations and financial performance. For example, the United States recently
passed the Inflation Reduction Act, which provides for a minimum tax equal to 15% of the adjusted financial statement
income  of  certain  large  corporations,  as  well  as  a  1%  excise  tax  on  certain  share  buybacks  by  public  corporations  that
would  be  imposed  on  such  corporations.  In  addition,  it  is  uncertain  if  and  to  what  extent  various  states  will  conform  to
newly enacted federal tax legislation. Changes in corporate tax rates, the realization of net deferred tax assets relating to
our operations, the taxation of foreign earnings, and the deductibility of expenses could have a material impact on the value
of our deferred tax assets, could result in significant one-time charges, and could increase our future U.S. tax expense.

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

As a public company listed in the United States, we incur, and will continue to incur, particularly now that we no
longer qualify as a “smaller reporting company,” significant legal, accounting and other costs. These 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.

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 Part I, Item 1A. “Risk Factors,” and “Special Note Regarding Forward-Looking Statements.”

Overview

We  are  a  clinical-stage  biopharmaceutical  company  focused  on  developing  novel  drug  candidates  for  immuno-
inflammatory  diseases.    In  addition  to  developing  our  novel  drug  candidates,  we  are  pursuing  strategic  alternatives,
including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval for and/or commercialize our novel drug candidates.

Clinical Programs

Zunsemetinib, an Investigational Oral MK2 Inhibitor

We  are  developing  zunsemetinib,  an  investigational  oral,  novel,  small  molecule  selective  MK2  inhibitor,  as  a
potential for the treatment for rheumatoid arthritis, hidradenitis suppurativa and psoriatic arthritis.  MK2 is a key regulator
of  pro-inflammatory  mediators  including  TNFα,  IL1β,  IL6,  IL8,  IL17  and  other  essential  pathogenic  signals  in  chronic
immuno-inflammatory diseases, as well as in oncology.  As an oral drug candidate, we are developing zunsemetinib as a
potential  alternative  to  injectable  anti-TNF/IL1/IL6/IL17  biologics  and  JAK  inhibitors  for  treating  certain  immuno-
inflammatory diseases. Zunsemetinib has been adopted as the nonproprietary name for ATI-450.

Moderate to Severe Rheumatoid Arthritis

In  December  2021,  we  initiated  a  Phase  2b  randomized,  multicenter,  double-blind,  parallel  group,  placebo-
controlled,  dose-ranging  trial  to  investigate  the  efficacy,  safety,  tolerability,  pharmacokinetics  and  pharmacodynamics  of
multiple doses (20 mg and 50 mg twice daily) of zunsemetinib in combination with methotrexate in subjects with moderate
to severe rheumatoid arthritis (ATI-450-RA-202). This trial consists of a 12-week treatment period and a 30-day follow-up
period,  and  seeks  to  enroll  approximately  240  subjects  in  the  United  States  and  in  multiple  countries  in  Europe.  The
primary endpoint is the proportion of subjects achieving ACR20 at week 12. We expect topline data in the second half of
2023.

Moderate to Severe Hidradenitis Suppurativa

In  December  2021,  we  initiated  a  Phase  2a,  randomized,  multicenter,  double-blind,  placebo-controlled  trial  to
investigate the efficacy, safety, tolerability, pharmacokinetics and pharmacodynamics of zunsemetinib (50 mg twice daily)
in subjects with moderate to severe hidradenitis suppurativa (ATI-450-HS-201). This trial consists of a 12-week treatment
period and a 30-day follow-up period. The primary endpoint is the change in inflammatory nodule and abscess count at
week 12. The trial has completed enrollment with 95 subjects randomized in the United States. We expect topline data in
March of 2023.

Moderate to Severe Psoriatic Arthritis

In  June  2022,  we  initiated  a  Phase  2a,  randomized,  multicenter,  double-blind,  placebo-controlled  trial  to
investigate the efficacy, safety, tolerability, pharmacokinetics and pharmacodynamics of zunsemetinib (50 mg twice daily)
in subjects with moderate to severe psoriatic arthritis (ATI-450-PsA-201). This trial consists of a 12-week treatment period
and  a  30-day  follow-up  period,  and  seeks  to  enroll  approximately  70  subjects  in  the  United  States  and  in  Poland.  The
primary endpoint is the proportion of subjects achieving ACR20 at week 12.  We expect topline data by the end of 2023.

Table of Contents

ATI-1777, an Investigational Topical “Soft” JAK 1/3 Inhibitor

We  are  developing  ATI-1777,  an  investigational  topical  “soft”  JAK  1/3  inhibitor,  as  a  potential  treatment  for
moderate to severe atopic dermatitis. “Soft” JAK inhibitors are designed to be topically applied and active in the skin, but
rapidly metabolized and inactivated when they enter the bloodstream, which may result in low systemic exposure.

In May 2022, we initiated a Phase 2b, multicenter, randomized, double-blind, vehicle-controlled, parallel-group
trial to determine the efficacy, safety, tolerability and pharmacokinetics of ATI-1777 in subjects with moderate to severe
atopic dermatitis (ATI-1777-AD-202). In this trial, we are exploring multiple concentrations of twice daily treatment with
ATI-1777  and  a  single  concentration  of  once  daily  treatment  with  ATI-1777,  in  patients  12  years  and  older.  This  trial
consists of a 4-week treatment period and a 2-week follow-up period, and seeks to enroll approximately 240 subjects in the
United States. The primary endpoint is the percentage change from baseline in EASI score at week 4. We expect topline
data mid-2023.

ATI-2138, an Investigational Oral Covalent ITK/JAK3 Inhibitor

We are developing ATI-2138, an investigational oral covalent ITK/JAK3 inhibitor, as a potential treatment for T
cell-mediated autoimmune diseases.  The ITK/JAK3 compound interrupts T cell signaling through the combined inhibition
of ITK/JAK3 pathways in lymphocytes. We have selected ulcerative colitis as the intended first clinical development target
for ATI-2138. We are also exploring additional indications that are relevant to the mechanism of action.

In October 2022, we submitted a new IND for ATI-2138 for the treatment of ulcerative colitis, which was allowed
by  the  FDA  in  November  2022.  In  December  2022,  we  initiated  a  Phase  1  placebo-controlled,  randomized,  multiple
ascending dose (MAD) trial to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of ATI-2138 in
healthy  volunteers  (ATI-2138-PKPD-102).  This  trial  seeks  to  enroll  approximately  60  healthy  volunteers  in  the  United
States. We expect topline data in the second half of 2023.

Preclinical Programs

ATI-2231, an Investigational Oral MK2 Inhibitor

We are exploring the use of ATI-2231, an investigational oral MK2 inhibitor designed to have a long half-life, as a
potential treatment for pancreatic cancer and metastatic breast cancer as well as in preventing bone loss in patients with
metastatic breast cancer. We expect clinical development activities to be initiated in 2023, which we expect to advance as a
collaboration with an academic third party.

Discovery Programs

We  are  developing  oral  gut-biased  JAK  inhibitors  with  limited  systemic  exposure  as  potential  treatments  for
inflammatory bowel disease. In addition, we are engaged in research to identify brain penetrant kinase inhibitor candidates
as potential treatments for neurodegenerative diseases.

Financial Overview

Since our inception, we have incurred significant net losses.  Our net loss was $86.9 million for the year ended
December  31,  2022  and  $90.9  million  for  the  year  ended  December  31,  2021.   As  of  December  31,  2022,  we  had  an
accumulated  deficit  of  $682.3  million.   We  expect  to  incur  significant  expenses  and  operating  losses  for  the  foreseeable
future as we advance our drug candidates from discovery through preclinical and clinical development.  In addition, our
drug candidates, even if they are approved by regulatory agencies for marketing, may not achieve commercial success.  We
may  also  not  be  successful  in  pursuing  strategic  alternatives,  including  identifying  and  consummating  transactions  with
third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  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.  We also expect to add additional personnel to
support our operational plans and strategic direction. As a result, we will need substantial additional funding to support our
continuing operations.

60

Table of Contents

We have historically financed our operations primarily with sales of equity securities and incurring indebtedness
in the form of loans from commercial lenders.  In the near term, we expect to finance our operations through these and
other  capital  sources,  including  potential  partnerships  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 of one or more of our drug candidates.  

Impact of Macroeconomic Conditions on Our Business

Unfavorable conditions in the economy both in the United States and abroad may negatively affect the growth of
our business and our results of operations. For example, macroeconomic events, including the COVID-19 pandemic, rising
inflation,  the  U.S.  Federal  Reserve  raising  interest  rates  and  the  Russia-Ukraine  war,  have  led  to  economic  uncertainty
globally.  The  effect  of  macroeconomic  conditions  may  not  be  fully  reflected  in  our  results  of  operations  until  future
periods. If, however, economic uncertainty increases or the global economy worsens, our business, financial condition and
results  of  operations  may  be  harmed.  For  further  discussion  of  the  potential  impacts  of  macroeconomic  events  on  our
business, financial condition, and operating results, see the section titled “Risk Factors.”

Acquisition and License Agreements

Agreement and Plan of Merger with Confluence

In 2017, we entered into an Agreement and Plan of Merger, or the Confluence Agreement, with Confluence Life
Sciences, Inc. (now known as Aclaris Life Sciences, Inc.), or 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,  Merger  Sub  merged  with  and  into  Confluence,  with  Confluence  surviving  as  our
wholly-owned subsidiary.

Under  the  Confluence  Agreement,  we  have  agreed  to  pay  the  former  Confluence  equity  holders  aggregate
remaining  contingent  consideration  of  up  to  $75.0  million  based  upon  the  achievement  of  specified  regulatory  and
commercial milestones set forth in the Confluence Agreement.  In addition, we have agreed to pay the former Confluence
equity holders 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 to the payments described above, 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 Confluence equity holders a portion of any consideration received from such sale, license or transfer in
specified circumstances.  

Asset Purchase Agreement with EPI Health

In 2019, we entered into an asset purchase agreement with EPI Health, LLC, or EPI Health, pursuant to which we
sold  the  worldwide  rights  to  RHOFADE  (oxymetazoline  hydrochloride)  cream,  1%,  or  RHOFADE,  which  included  the
assignment of certain licenses for related intellectual property assets, or the Disposition.  

Pursuant to the asset purchase agreement, EPI Health paid us closing consideration of $35.2 million.  In addition,
EPI Health has agreed to pay us (i) potential sales milestone payments of up to $20.0 million in the aggregate upon the
achievement of specified levels of net sales of products covered by the agreement, (ii) a specified high single-digit royalty
calculated as a percentage of net sales, on a product-by-product and country-by-country basis, until the date that the patent
rights related to a particular product, such as RHOFADE, have expired, provided, that with respect to sales of RHOFADE
in any territory outside of the United States, such royalty shall be paid on a country-by-country basis until the date that the
RHOFADE patent rights in the particular country have expired or, if later, 10 years from the date of the first commercial
sale of RHOFADE in such country and (iii) 25% of any upfront, license, milestone, maintenance or fixed payment received
by  EPI  Health  in  connection  with  any  license  or  sublicense  of  the  assets  transferred  in  the  Disposition  in  any  territory
outside of the United States, subject to specified exceptions.  In addition, EPI Health has agreed to assume our obligation to
pay specified royalties and milestone payments under certain agreements with third parties.

License Agreement with Eli Lilly and Company

In August 2022, we entered into a non-exclusive patent license agreement with Eli Lilly and Company, or Lilly.
Under the license agreement, we granted Lilly non-exclusive rights under certain patents and patent applications that we
exclusively  license  from  a  third  party.  The  patents  and  patent  applications  relate  to  the  use  of  baricitinib,  Lilly’s  JAK
inhibitor, to treat alopecia areata. Under the license agreement, Lilly has agreed to pay us an upfront payment, regulatory
and  commercial  milestone  payments,  anniversary  payments,  and  a  low  single-digit  royalty  calculated  as  a  percentage  of
Lilly’s net sales of baricitinib for the treatment of alopecia areata. We have separate contractual obligations under which we
have  agreed  to  pay  to  third  parties  an  amount  equal  to  any  regulatory  and  commercial  milestone  payments  we  receive
under the Lilly license agreement, as well as a portion of the upfront consideration and a portion of the royalties we may
receive under the license agreement.

 Upon execution of the agreement, we received $17.6 million from Lilly, a portion of which represented payments
for  regulatory  and  commercial  milestones  that  were  deemed  to  have  been  achieved  as  of  the  execution  of  the  license
agreement.  We  remain  eligible  to  receive  future  milestone  payments,  all  of  which  will  be  paid  by  us  to  third  parties
following  receipt  as  described  above.  We  recorded  amounts  paid  to  third  parties  of  $7.3  million  during  the  year  ended
December 31, 2022.

During the year ended December 31, 2022, we received $0.2 million in royalties from Lilly, a portion of which

was payable to third parties.

License Agreement with Pediatrix Therapeutics, Inc.

In  November  2022,  we  entered  into  a  license  agreement  with  Pediatrix  Therapeutics,  Inc.,  or  Pediatrix,  under
which we granted Pediatrix the exclusive rights to develop, manufacture and commercialize ATI-1777 in Greater China.
Pediatrix  has  agreed  to  pay  us  an  upfront  payment,  development,  regulatory  and  commercial  milestone  payments,  and  a
tiered royalty ranging from a low-to-high single digit percentage of net sales of ATI-1777 by Pediatrix in Greater China. A
portion of consideration received from Pediatrix is payable to the former Confluence equity holders as described above.

Upon  execution  of  the  agreement,  we  received  an  upfront  payment  of  $5.0  million  from  Pediatrix,  a  portion  of

which was payable to the former Confluence equity holders as described above.

Components of Our Results of Operations

Revenue

Contract Research

We earn revenue from the provision of laboratory services.  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.

Licensing

Licensing revenue primarily consists of upfront consideration, royalties and milestone payments earned pursuant

to license and acquisition agreements with third parties, as described above.  

Other

Other revenue consists of amounts earned from the sub-sublease of our office space, which was terminated during

the year ended December 31, 2022.

Cost and Expenses

Cost of Revenue

Cost of revenue consists of the costs incurred in connection with the provision of contract research services.  Cost

of revenue primarily includes:

● 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

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 clinical trial
sites and consultants that conduct our clinical trials and preclinical studies, and investigator-initiated trials;

● manufacturing scale-up expenses and the cost of acquiring and manufacturing active pharmaceutical

ingredients and preclinical and clinical trial materials, including domestic technology transfer expenses;

● quality assurance and quality control costs;
● outsourced professional scientific development services;
● medical affairs expenses related to our drug candidates;
● employee-related expenses, which include salaries, benefits and stock-based compensation;
● 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; and
● laboratory materials and supplies used to support our research activities.

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  to  continue  to  incur  research  and  development
expenses in the near term as we continue the clinical development of zunsemetinib as a potential treatment for moderate to
severe  rheumatoid  arthritis,  moderate  to  severe  hidradenitis  suppurativa  and  moderate  to  severe  psoriatic  arthritis,  ATI-
1777  as  a  potential  treatment  for  moderate  to  severe  atopic  dermatitis,  ATI-2138  as  a  potential  treatment  for  T  cell-
mediated  autoimmune  diseases,  ATI-2231  as  a  potential  treatment  for  pancreatic  cancer  and  metastatic  breast  cancer  as
well  as  in  preventing  bone  loss  in  patients  with  metastatic  breast  cancer,  and  as  we  continue  the  development  of  our
preclinical compounds and discover and develop additional 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,  clinical  trial  sites,  regulatory  agencies  and  third  parties  that  manufacture  our  preclinical  and  clinical  trial
materials and are tracked on a program-by-program basis.  We do not allocate personnel costs or other indirect expenses to
specific research and development programs.  

The successful development of our drug candidates is highly uncertain. 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 subjects;
● the number of subjects that ultimately participate in the trials;
● the number of doses subjects receive;

63

Table of Contents

● the impact on the recruitment, enrollment, conduct and timing of our clinical trials due to the COVID-19

pandemic;

● the duration of subject follow-up; and
● the results of our clinical trials.

Our  expenditures  are  subject  to  additional  uncertainties,  including  the  preparation  of  regulatory  filings  for  our
drug candidates.  We may obtain unexpected results from our clinical trials or other development activities.  We may elect
to discontinue, delay or modify the development, including 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.  

General and Administrative

General  and  administrative  expenses  consist  principally  of  salaries  and  related  costs,  including  stock-based
compensation, for personnel in executive, administrative, finance and legal functions.  General and administrative expenses
also include facility-related costs, patent filing and prosecution costs, professional fees for legal, auditing and tax services,
investor relations costs, business development costs, insurance costs and travel expenses.

Licensing

Licensing  expenses  consist  of  third-party  contractual  obligations  incurred  under  license  and  acquisition

agreements with third parties, as described above.

Revaluation of Contingent Consideration

Revaluation  of  contingent  consideration  consists  of  changes  in  the  fair  value  of  our  contingent  consideration

liability between reporting dates.

Other Income (Expense), Net

Other income (expense), net primarily consists of interest earned on our cash, cash equivalents and marketable

securities and in prior periods included interest expense related to debt obligations.

Critical Accounting Estimates

This  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  is  based  on  our  consolidated
financial statements which have been prepared in accordance with 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, the 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 judgments on an ongoing basis. Our actual
results may differ from these estimates under different assumptions or conditions.  

While our significant accounting policies are described in more detail in 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.  

Intangible Assets

Our intangible assets include both definite-lived and indefinite-lived assets.  Our definite-lived intangible assets
consist of a drug discovery platform acquired through the acquisition of Confluence.  Definite-lived intangible assets are
amortized over their estimated useful life based on the pattern over which the intangible assets are consumed or otherwise

64

Table of Contents

used up.  If that pattern cannot be reliably determined, the straight-line method of amortization is used.  Our indefinite-
lived intangible assets consist of an in-process research and development, or IPR&D, drug candidate also 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.  

Definite-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 intangible asset is less than its carrying value.
 The fair value of an intangible asset is dependent on significant unobservable inputs including the estimated future cash
flows of the asset.  

There were no impairment losses recorded during the years ended December 31, 2022 and 2021.  

Contingent Consideration

We initially recorded a contingent consideration liability at fair value on the date of acquisition related to future
potential payments resulting from the acquisition of Confluence based upon significant unobservable inputs including the
achievement  of  development,  regulatory  and  commercial  milestones,  as  well  as  estimated  future  sales  levels  and  the
discount  rates  applied  to  calculate  the  present  value  of  the  potential  payments.  Significant  judgement  was  involved  in
determining the appropriateness of these assumptions.  These assumptions are considered Level 3 inputs.  Revaluation of
our contingent consideration liability can result from changes to one or more of these assumptions.  These assumptions are
highly  dependent  on  the  outcome  and  timing  of  the  development  of  our  drug  candidates.  We  evaluate  the  fair  value
estimate of our contingent consideration liability on a quarterly basis with changes, if any, recorded as income or expense
in our consolidated statement of operations.  Any such changes could have a material impact on our financial results.

The fair value of contingent consideration is estimated using a probability-weighted expected payment model for
regulatory milestone payments and a Monte Carlo simulation model for commercial milestone and royalty payments and
then  applying  a  risk-adjusted  discount  rate  to  calculate  the  present  value  of  the  potential  payments.    Significant
assumptions  used  in  our  estimates  include  the  probability  of  achieving  regulatory  milestones  and  commencing
commercialization,  which  are  based  on  an  asset’s  current  stage  of  development  and  a  review  of  existing  clinical  data.
Probability of success assumptions ranged between 10% and 40% at December 31, 2022 and 2021. Additionally, estimated
future  sales  levels  and  the  risk-adjusted  discount  rate  applied  to  the  potential  payments  are  also  significant  assumptions
used  in  calculating  the  fair  value.  The  discount  rate  ranged  between  9.8%  and  10.2%  depending  on  the  year  of  each
potential payment.

During  the  year  ended  December  31,  2022,  we  updated  future  sales  level  assumptions  for  zunsemetinib.  These
changes, and the impact from the passage of time, resulted in a net charge of $4.7 million during the year ended December
31, 2022.

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.  

65

Table of Contents

We  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.

We estimate the fair value of each stock option grant using the Black-Scholes option-pricing model.  Historically,
we  estimated  expected  volatility  based  on  historical  volatility  of  a  set  of  peer  companies,  which  are  publicly  traded.
Starting in 2022, we estimated expected volatility based on our stock price's historical volatility, as we determined that we
had 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.

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, 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

Contract Research

Contract research revenue was $4.4 million and $5.8 million for the years ended December 31, 2022 and 2021,
respectively, and was comprised of fees earned from the provision of laboratory services to our clients.  The decrease was
driven  by  lower  overall  hours  billed,  partially  due  to  an  increased  focus  on  internal  development  programs,  which  was
offset by a higher average billing rate.

Licensing

Licensing  revenue  was  $25.1  million  and  $0.8  million  for  the  years  ended  December  31,  2022  and  2021,
respectively.  The  increase  was  primarily  driven  by  $17.6  million  of  upfront  and  milestone  payments  received  under  the
Lilly agreement and the $5.0 million upfront payment received under the Pediatrix agreement.

Cost and Expenses

Cost of Revenue

Cost of revenue was $4.0 million and $4.7 million for the years ended December 31, 2022 and 2021, respectively,
and in each case related to providing laboratory services to our clients.  Changes in cost of revenue generally correlate to
changes in contract research revenue.  Cost of revenue decreased during the year ended December 31, 2022 due to lower
variable costs resulting from the decrease in hours billed, partially offset by an increase in fixed overhead costs, including
personnel-related costs.

The increase in expenses for zunsemetinib during the year ended December 31, 2022 compared to the year ended
December  31,  2021  was  primarily  due  to  costs  associated  with  clinical  development  activities  for  a  Phase  2b  trial  in
subjects  with  rheumatoid  arthritis,  which  initiated  in  December  2021,  a  Phase  2a  trial  in  subjects  with  hidradenitis
suppurativa, which initiated in December 2021, a Phase 2a trial in subjects with psoriatic arthritis, which initiated in June
2022, and several ancillary clinical trials.

ATI-1777

The  increase  in  expenses  for  ATI-1777  during  the  year  ended  December  31,  2022  compared  to  the  year  ended
December 31, 2021 was primarily due to higher costs associated with drug candidate manufacturing and other preclinical
development activities as well as costs associated with a Phase 2b clinical trial in subjects with atopic dermatitis. Lower

67

    
 
 
 
Table of Contents

costs associated with a Phase 2a clinical trial in subjects with atopic dermatitis, which commenced in 2020 and concluded
in 2021, partially offset the overall increase in expenses.

ATI-2138

Expenses  for  ATI-2138  were  higher  during  the  year  ended  December  31,  2022  compared  to  the  year  ended
December 31, 2021 primarily due higher costs associated with preclinical development activities as well as costs associated
with a Phase 1 SAD trial, which initiated in December 2021, and a Phase 1 MAD trial, which initiated in December 2022.

ATI-2231

Expenses  for  ATI-2231  were  higher  during  the  year  ended  December  31,  2022  compared  to  the  year  ended
December  31,  2021  primarily  due  to  preclinical  development  activities  and  IND-enabling  studies  as  we  progressed  the
program toward IND submission.

Discovery

Expenses related to discovery increased during the year ended December 31, 2022 compared to the year ended
December  31,  2021  due  to  continued  investment  in  our  discovery-stage  programs  as  we  progressed  programs  toward
candidate selection.

Personnel and stock-based compensation

Personnel and stock-based compensation expenses increased in the aggregate during the year ended December 31,
2022 compared to the year ended December 31, 2021 primarily due to an increase in costs associated with higher average
headcount, which was partially offset by a decrease in stock-based compensation expense mainly attributable to forfeiture
credits recorded during the period.

Personnel and stock-based compensation expenses increased during the year ended December 31, 2022 compared
to  December  31,  2021  primarily  due  to  higher  average  headcount  and  an  increase  in  stock-based  compensation  expense
associated  with  new  equity  awards  granted  in  2022,  partially  offset  by  lower  costs  associated  with  the  separation  of
executive officers.  

Professional and legal fees

Professional  and  legal  fees,  including  accounting,  investor  relations  and  corporate  communication  costs,  were
lower during the year ended December 31, 2022 compared to the year ended December 31, 2021 primarily as a result of
lower accounting and other professional expenses due to a reduction in temporary staffing costs.

Table of Contents

Facility and support services

Facility and support services, including general office expenses, information technology costs and other expenses,
increased during the year ended December 31, 2022 compared to the year ended December 31, 2021 primarily due to an
increase in overhead expenses, including increases in tax and license fees and information technology support costs.

Licensing

We incurred licensing expense during the year ended December 31, 2022 due to amounts payable to third parties
under third-party license and acquisition agreements. We did not incur licensing expense during the year ended December
31, 2021.

Revaluation of Contingent Consideration

The fair value of our contingent consideration liability increased during the year ended December 31, 2022 mainly

due to an increase in future sales level assumptions for zunsemetinib and the passage of time.

The  fair  value  of  our  contingent  consideration  liability  increased  during  the  year  ended  December  31,
2021 primarily from updates to the probability of success and estimated future sales level assumptions as a result of the
completion of a Phase 2a clinical trial of zunsemetinib in subjects with rheumatoid arthritis, as well as the completion of a
Phase 2a clinical trial of ATI-1777 in subjects with atopic dermatitis.  Additionally, the inclusion of estimated future sales
of zunsemetinib as a potential treatment for hidradenitis suppurativa and psoriatic arthritis, which are additional planned
indications for zunsemetinib, also contributed to the increase during the year ended December 31, 2021.

Other Income (Expense), net

Other  income  (expense),  net  increased  during  the  year  ended  December  31,  2022  compared  to  the  year  ended
December 31, 2021 primarily due to there being no interest expense associated with the Loan and Security Agreement with
Silicon Valley Bank, or SVB, which was repaid in July 2021, and higher interest income on investment portfolio balances.

Liquidity and Capital Resources

Overview

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  and  incurring  indebtedness  in  the  form  of  loans  from
commercial lenders.  We may engage in additional debt and equity financing transactions in order to raise funds.  We may
receive royalties and milestone payments from third-party licensing and acquisition agreements. In addition, to the extent
we are able to consummate transactions with potential third-party partners to further develop, obtain marketing approval
for  and/or  commercialize  our  drug  candidates,  we  may  receive  upfront  payments,  milestone  payments  or  royalties  from
such arrangements that would increase our liquidity.

As of December 31, 2022, we had cash, cash equivalents and marketable securities of $229.8 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,  other  than  our  contingent  obligations  under  the  Confluence  Agreement,  which  is
summarized above under “Overview—Acquisition and License Agreements,” and our lease obligations.

Equity Financing

Sale of Common Stock under At-the-Market Facility

In April 2022, we sold 4,838,709 shares of our common stock at a weighted average price per share of $15.50, for
aggregate gross proceeds of $75.0 million, pursuant to a sales agreement with SVB Securities LLC and Cantor Fitzgerald
& Co., as sales agents, dated May 20, 2021.  We paid selling commissions and other fees of $2.2 million in connection with
the sale.

June 2021 Public Offering

In June 2021, we closed a public offering in which we sold 8,098,592 shares of common stock at a price to the
public  of  $17.75  per  share,  for  aggregate  gross  proceeds  of  $143.8  million.  We  paid  underwriting  discounts  and
commissions of $8.6 million, and also 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
$134.9 million.

January 2021 Public Offering

In January 2021, we closed a public offering in which we sold 6,306,271 shares of common stock at a price to the
public  of  $17.50  per  share,  for  aggregate  gross  proceeds  of  $110.4  million.  We  paid  underwriting  discounts  and
commissions of $6.6 million, and also incurred expenses of $0.4 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
$103.3 million.

Equity Purchase Agreement with Lincoln Park Capital Fund, LLC  

In  August  2020,  we  entered  into  a  purchase  agreement,  or  the  Purchase  Agreement,  with  Lincoln  Park  Capital
Fund, LLC, or Lincoln Park, which provided that, upon the terms and subject to the conditions and limitations set forth
therein, we could sell to Lincoln Park, at our discretion, up to $15.0 million of shares of our common stock over the 36-
month  term  of  the  Purchase  Agreement.  Upon  execution  of  the  Purchase  Agreement,  we  issued  121,584  shares  of  our
common  stock  to  Lincoln  Park  as  commitment  shares  in  accordance  with  the  closing  conditions  contained  within  the
Purchase Agreement. The commitment shares were valued using the closing price of our common stock on the effective
date of the Purchase Agreement resulting in an aggregate fair value of $0.3 million. Through December 31, 2020, we sold
2,111,170 shares of our common stock to Lincoln Park under the Purchase Agreement for net proceeds of $7.7 million.  We
terminated  the  Purchase  Agreement  in  January  2021  in  connection  with  the  public  offering  of  common  stock  described
above. We did not sell any additional shares prior to terminating the Purchase Agreement.

Debt Financing

Loan and Security Agreement with Silicon Valley Bank  

In March 2020, we entered into a Loan and Security Agreement with SVB.  The Loan and Security Agreement
provided for $11.0 million in term loans, of which we borrowed the entire amount on March 30, 2020.  In July 2021, we
repaid in full the $11.0 million that was outstanding under the Loan and Security Agreement, together with all accrued and
unpaid interest and fees as of the payoff date, for a total payment of $11.7 million.

Cash Flows

Cash  and  cash  equivalents  were  $45.3  million  as  of  December  31,  2022  compared  to  $27.3  million  as  of
December 31, 2021.  We also had $184.5 million in short- and long-term marketable securities as of December 31, 2022
compared to $198.3 million as of December 31, 2021.

Net cash used in operating activities increased for the year ended December 31, 2022 compared to the year ended
December 31, 2021 primarily as a result of higher net losses after adjusting for revaluation of contingent consideration and
other non-cash items and an increase in cash paid for prepaid expenses and other assets. This change was partially offset by
a decrease in cash paid to settle outstanding accounts payable.

The decrease in non-cash adjustments to reconcile net loss to net cash used in operating activities was mainly the
result of a decrease in revaluation of contingent consideration during the year ended December 31, 2022 compared to the
year ended December 31, 2021. The decrease in revaluation of contingent consideration during the year ended December
31, 2022 compared to the year ended December 31, 2021 was primarily the result of higher charges during the year ended
December 31, 2021 from updates to the probability of success and estimated future sales level assumptions as a result of
the completion of a Phase 2a clinical trial of zunsemetinib in subjects with rheumatoid arthritis, as well as the completion
of a Phase 2a clinical trial of ATI-1777 in subjects with atopic dermatitis. Additionally, the inclusion of estimated future
sales  of  zunsemetinib  as  a  potential  treatment  for  hidradenitis  suppurativa  and  psoriatic  arthritis,  which  are  additional
planned indications for zunsemetinib, also contributed to the higher charges during the year ended December 31, 2021.

The change in net cash provided by investing activities for the year ended December 31, 2022 compared to net
cash used in investing activities for the year ended December 31, 2021 primarily resulted from higher sales and maturities
of  marketable  securities  during  the  year  ended  December  31,  2022,  which  were  used  to  fund  our  operations,  and  a
reduction of purchases of marketable securities, which were higher during the year ended December 31, 2021 following
our January 2021 and June 2021 public offerings.

Cash provided by financing activities decreased for the year ended December 31, 2022 compared to December 31,
2021 primarily due to our January 2021 and June 2021 public offerings, partially  offset  by  the  proceeds  from  our  April

Funding Requirements

We anticipate we will incur net losses in the near term as we continue the clinical development of zunsemetinib as
a potential treatment for moderate to severe rheumatoid arthritis, moderate to severe hidradenitis suppurativa and moderate
to  severe  psoriatic  arthritis,  ATI-1777  as  a  potential  treatment  for  moderate  to  severe  atopic  dermatitis,  ATI-2138  as  a
potential treatment for T cell-mediated autoimmune diseases and ATI-2231 as a potential treatment for pancreatic cancer
and  metastatic  breast  cancer  as  well  as  in  preventing  bone  loss  in  patients  with  metastatic  breast  cancer,  continue  the
development of our preclinical compounds, and continue to discover and develop additional drug candidates.  We may not
be able to generate revenue from these programs if, among other things, our clinical trials are not successful, the FDA does
not  approve  our  drug  candidates  currently  in  clinical  trials  when  we  expect,  or  at  all,  or  we  are  not  able  to  identify  and
consummate transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize
our drug candidates.  

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, legal and other regulatory expenses, and
administrative and overhead costs.  We expect to add additional personnel to support our operational plans and strategic
direction. Our future funding requirements will be heavily determined by the resources needed to support the development
of our drug candidates.  

As a publicly traded company, we incur and will continue to incur significant legal, accounting and other similar
expenses.  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 could increase our compliance
costs.  

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.  We will
require additional capital to complete the clinical development of zunsemetinib, ATI-1777 and ATI-2138, to develop our
preclinical compounds, and to support our discovery efforts.  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. Our ability to raise additional capital may be adversely impacted by potential
worsening global economic conditions caused by a variety of factors including geopolitical tensions, rising interest rates,
and inflationary pressures. If we are unable to raise sufficient additional capital or generate revenue from transactions with
potential  third-party  partners  for  the  development  and/or  commercialization  of  our  drug  candidates,  we  may  need  to
substantially curtail our planned operations.  

72

    
    
 
 
Table of Contents

We may raise additional capital through the sale of equity or debt securities. In such an event, our stockholders’
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  and  development  of  pharmaceutical
drugs, we are unable to estimate the exact amount of our working capital requirements. Our funding requirements in the
near term will depend on many factors, including:

● the number and development requirements of the drug candidates that we may pursue;
● the  scope,  progress,  results  and  costs  of  preclinical  development,  laboratory  testing  and  conducting  preclinical

and clinical trials for our drug candidates;

● the costs, timing and outcome of regulatory review of our drug candidates;
● the extent to which we in-license or acquire additional drug candidates and technologies;
● 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;

● the impact on the timing of our preclinical studies, the recruitment, enrollment, conduct and timing of our clinical

trials and our business due to the COVID-19 pandemic;

● our ability to identify and consummate transactions with third-party partners to further develop, obtain marketing

approval for and/or commercialize our drug candidates; and

● our ability to earn revenue as a result of licenses to, or partnerships or other arrangements with, third parties.

See “Risk Factors” for additional risks associated with our substantial capital requirements.

Leases

We  occupy  space  for  our  headquarters  in  Wayne,  Pennsylvania  under  a  sublease  agreement  which  has  a  term
through October 2023.  In December 2020, we entered into a sub-sublease agreement under which we sub-subleased 8,115
square feet.  The sub-sublease was terminated in December 2022. We also occupy office and laboratory space in St. Louis,
Missouri under a sublease agreement which has a term through June 2029.

Our  aggregate  remaining  lease  payment  obligations  for  these  two  spaces  was  $2.9  million  as  of  December  31,

2022. In February 2023, we added an additional 6,261 square feet of office and laboratory space in St. Louis.

Agreement and Plan of Merger – Confluence

Under the Confluence Agreement, we agreed to pay the former Confluence equity holders aggregate remaining
contingent  consideration  of  up  to  $75.0  million  based  upon  the  achievement  of  specified  regulatory  and  commercial
milestones  set  forth  in  the  Confluence  Agreement.    In  addition,  we  have  agreed  to  pay  the  former  Confluence  equity
holders  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 to the payments described above, 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 Confluence equity holders a portion of any consideration received from such sale, license or transfer in
specified circumstances.  

R&D Obligations

We  enter  into  contracts  in  the  normal  course  of  business  with  CROs,  contract  manufacturing  organizations  and
other service providers for clinical trials, preclinical 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.

Segment Information

We  have  two  reportable  segments,  therapeutics  and  contract  research.    The  therapeutics  segment  is  focused  on
identifying  and  developing  innovative  therapies  to  address  significant  unmet  needs  for  immuno-inflammatory  diseases.
 The contract research segment earns revenue from the provision of laboratory services.

Recently Issued 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.   We  adopted  this  standard  as  of  January  1,  2020,  the  impact  of  which  on  our
consolidated financial statements was not significant.  

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.  We adopted this standard as of January 1, 2020, the
impact of which on our consolidated financial statements was not significant.    

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.  We adopted this standard as of January 1, 2020, the impact of which on our consolidated financial
statements was not significant.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Our  cash  equivalents  and  marketable  securities  consist  of  money  market  funds,  asset-backed  debt  securities,
commercial paper, corporate debt securities, U.S. government debt securities and U.S. government agency debt securities.
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.

Inflation Risk

Inflation  generally  affects  us  by  increasing  our  cost  of  labor.  Although  inflation  has  increased  generally  in  the
United  States  in  recent  months,  we  do  not  believe  that  inflation  has  had  a  material  effect  on  our  business,  financial
condition or results of operations during the year ended December 31, 2022.

Report of Independent Registered Public Accounting Firm

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

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Aclaris Therapeutics, Inc. and its subsidiaries (the
“Company”) as of December 31, 2022 and 2021, 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, 2022,
including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the
Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal
Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial
position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of
the three years in the period ended December 31, 2022 in conformity with accounting principles generally accepted in the
United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control
over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework
(2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting,
included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our
responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal
control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company
Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange
Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and
perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material
misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained
in all material respects.

Our audits of the consolidated financial statements 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. Our audit of internal control over financial reporting included obtaining an understanding of internal control
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and
operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other
procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our
opinions.

Definition and Limitations of Internal Control over Financial Reporting

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

76

Table of Contents

detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the
financial statements.

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

Critical Audit Matters

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

Fair Value of the Contingent Consideration Liability related to zunsemetinib

As described in Notes 2 and 3 to the consolidated financial statements, the Company’s contingent consideration balance 
was $33.1 million as of December 31, 2022, of which a significant portion of the liability relates to zunsemetinib. 
Management initially recorded a contingent consideration liability at fair value on the date of acquisition related to future 
potential payments resulting from the acquisition of Confluence based upon significant unobservable inputs including the 
achievement of development, regulatory and commercial milestones, as well as estimated future projected sales levels and 
the discount rates applied to calculate the present value of the potential payments. Management evaluates fair value 
estimates of the contingent consideration liability on a quarterly basis using a probability-weighted expected payment 
model for regulatory milestone payments and a Monte Carlo simulation model for commercial milestone and royalty 
payments and then applying a risk-adjusted discount rate to calculate the present value of the potential payment. Changes 
in the fair value of the contingent consideration are recorded as income or expense in the Company’s consolidated 
statement of operations and comprehensive loss. Significant assumptions used in management’s estimates include the 
probability of achieving regulatory milestones and commencing commercialization, which are based upon an asset’s 
current stage of development and review of existing clinical data.      

The principal considerations for our determination that performing procedures relating to the fair value of the contingent 
consideration liability related to zunsemetinib is a critical audit matter are (i) the significant judgment by management, 
when developing the fair value estimate, which in turn led to (ii) a high degree of auditor judgment, subjectivity and effort 
in performing procedures and evaluating management’s significant assumptions related to the probability of achieving 
regulatory milestones and commencing commercialization. In addition, the audit effort involved the use of professionals 
with specialized skill and knowledge.     

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our 
overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls 
relating to management’s contingent consideration evaluation, including controls over the valuation of the Company’s 
contingent consideration liability related to zunsemetinib. These procedures also included, among others, (i) testing 
management’s process for developing the fair value of the contingent consideration liability, (ii) evaluating the 
appropriateness of the probability-weighted expected payment and Monte Carlo simulation valuation models, (iii) testing 
the completeness and accuracy of the underlying data used in the models, and (iv) evaluating the reasonableness of the 
significant assumptions used by management related to the probability of achieving regulatory  milestones and 
commencing commercialization. Evaluating management’s assumptions related to the probability of achieving regulatory 
milestones and commencing commercialization involved evaluating whether the assumptions were reasonable considering 
the agreements associated with the transaction as well as the consistency with industry information, the stage of product 
development and whether the assumptions were consistent with evidence obtained in other areas of the audit.  Professionals 
with specialized skill and knowledge were used to assist in the evaluation of the Company’s probability-weighted expected 
payment and Monte Carlo simulation valuation models.

ACLARIS THERAPEUTICS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Nature of Business

Overview

Aclaris  Therapeutics,  Inc.  was  incorporated  under  the  laws  of  the  State  of  Delaware  in  2012.  In  August  2017,
Confluence  Life  Sciences,  Inc.  (now  known  as  Aclaris  Life  Sciences,  Inc.)  (“Confluence”)  was  acquired  by  Aclaris
Therapeutics,  Inc.  and  became  a  wholly  owned  subsidiary  thereof.    Aclaris  Therapeutics,  Inc.  and  its  wholly  owned
subsidiaries are referred to collectively as the “Company.”  The Company is a clinical-stage biopharmaceutical company
focused on developing novel drug candidates for immuno-inflammatory diseases.  In addition to developing its novel drug
candidates,  the  Company  is  pursuing  strategic  alternatives,  including  identifying  and  consummating  transactions  with
third-party partners, to further develop, obtain marketing approval for and/or commercialize its novel drug candidates.  

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.   As  of  December  31,  2022,  the
Company  had  cash,  cash  equivalents  and  marketable  securities  of  $229.8  million  and  an  accumulated  deficit  of  $682.3
million.  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  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, including clinical and preclinical testing of the Company’s drug candidates, will require significant
additional  financing.    The  future  viability  of  the  Company  is  dependent  on  its  ability  to  successfully  develop  its  drug
candidates  and  to  generate  revenue  from  identifying  and  consummating  transactions  with  third-party  partners  to  further
develop, obtain marketing approval for and/or commercialize its development assets or to raise additional capital to finance
its operations.  The Company will require additional capital to complete the clinical development of zunsemetinib (ATI-
450), ATI-1777, ATI-2138 and ATI-2231, to develop its preclinical compounds, and to support its discovery efforts.  

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 the Company to continue to implement its long-term business strategy.  The
Company's ability to raise additional capital may be adversely impacted by potential worsening global economic conditions
caused  by  a  variety  of  factors  including  geopolitical  tensions,  rising  interest  rates  and  inflationary  pressures.    If  the
Company  is  unable  to  raise  sufficient  additional  capital  or  generate  revenue  from  transactions  with  potential  third-party
partners for the development and/or commercialization of its drug candidates, it may need to substantially curtail planned
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.  

In  accordance  with  Accounting  Standards  Codification  (“ASC”)  Subtopic  205-40,  Disclosure  of  Uncertainties
about an Entity’s Ability to Continue as a Going Concern, the Company evaluated whether there are conditions and events,
considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within
one year after the date that its consolidated financial statements are issued.  As of the report date, the Company does not
believe that substantial doubt exists about its ability to continue as a going concern.  The Company believes its existing
cash, cash equivalents and marketable securities are sufficient to fund its operating and capital expenditure requirements
for a period greater than 12 months from the date of issuance of these consolidated financial statements.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with generally accepted
accounting principles 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.  All intercompany
transactions have been eliminated.  Based upon the Company’s revenue, the Company believes that gross profit does not

83

Table of Contents

provide  a  meaningful  measure  of  profitability  and,  therefore,  has  not  included  a  line  item  for  gross  profit  on  the
consolidated statement of operations.  

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year financial statement presentation.

Discontinued Operations

In September 2019, the Company announced the completion of a strategic review and its decision to refocus its

resources on its immuno-inflammatory development programs and to actively seek partners for its commercial products.  

As of December 31, 2022 and 2021, the Company had $2.2 million in accrued expenses reported as discontinued
operations in the Company’s consolidated balance sheet. During the year ended December 31, 2020, the Company reported
$0.1  million  as  income  from  discontinued  operations  in  the  Company’s  consolidated  statements  of  operations  and
comprehensive loss.  

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,  contingent  consideration  and  the
valuation  of  stock-based  awards.    Estimates  are  periodically  reviewed  in  light  of  changes  in  circumstances,  facts  and
experience.  As of the date of issuance of these financial statements, the Company is not aware of any specific event or
circumstance that would require an update to its estimates, assumptions and judgments or revise the carrying value of its
assets or liabilities.  Actual results could differ from the Company’s estimates.

Revenue Recognition

The Company accounts for revenue in accordance with 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.

Contract Research

The  Company  earns  contract  research  revenue  from  the  provision  of  laboratory  services.    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 and as
such,  recognizes  revenue  in  the  amount  which  it  has  the  right  to  invoice.    ASC  Topic  606  also  provides  an  optional
exemption, which the Company has elected to apply, from disclosing remaining performance obligations when revenue is
recognized  from  the  satisfaction  of  the  performance  obligation  in  accordance  with  the  “right  to  invoice”  practical
expedient.

84

Table of Contents

Licensing 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 and Royalty Payments – The Company considers any future potential milestones and sales-
based  royalties  to  be  variable  consideration.  The  Company  recognizes  revenue  from  development,  regulatory  and
anniversary milestone payments as they are achieved. The Company recognizes revenue from commercial milestones and
royalty payments as the sales occur.

Cash Equivalents

The Company considers all short-term, highly liquid investments with original maturities of three months or less
at  acquisition  date  to  be  cash  equivalents.    Cash  equivalents,  which  have  consisted  of  money  market  accounts  and
commercial paper, 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  marketable  securities  as  available-for-sale  securities.  The  Company’s  marketable
securities  are  measured  and  reported  at  fair  value  using  either  quoted  prices  in  active  markets  for  identical  securities  or
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  expense,  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.

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. Laboratory
equipment  is  depreciated  over  three  to  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
continuing operations.  

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.

85

Table of Contents

Intangible Assets

Intangible assets include both definite-lived and indefinite-lived assets.  Definite-lived intangible assets consist of
a drug discovery platform the Company acquired through the acquisition of Confluence.  Definite-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.
 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 is either amortized over its 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 or otherwise impaired.

Definite-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 intangible asset is less
than its carrying value.  

During the years ended December 31, 2022, 2021 and 2020, the Company did not record an IPR&D impairment.

Leases

Leases represent a company’s right to use an underlying asset and a corresponding obligation to make payments to
a  lessor  for  the  right  to  use  those  assets.    The  Company  evaluates  leases  at  their  inception  to  determine  if  they  are  an
operating lease or a finance lease.  A lease is accounted for as a finance lease if it meets one of the following five criteria:
the lease has a purchase option that is reasonably certain of being exercised, the present value of the future cash flows are
substantially all of the fair market value of the underlying asset, the lease term is for a significant portion of the remaining
economic  life  of  the  underlying  asset,  the  title  to  the  underlying  asset  transfers  at  the  end  of  the  lease  term,  or  if  the
underlying asset is of such a specialized nature that it is expected to have no alternative uses to the lessor at the end of the
term.  Leases that do not meet the finance lease criteria are accounted for as an operating lease.  

The  Company  recognizes  assets  and  liabilities  for  leases  at  their  inception  based  upon  the  present  value  of  all
payments due under the lease.  The Company uses an implicit interest rate to determine the present value of finance leases,
and  its  incremental  borrowing  rate  to  determine  the  present  value  of  operating  leases.    The  Company  determines
incremental  borrowing  rates  by  referencing  collateralized  borrowing  rates  for  debt  instruments  with  terms  similar  to  the
respective lease.  The Company recognizes expense for operating and finance leases on a straight-line basis over the term
of each lease, and interest expense related to finance leases is recognized over the lease term based on the effective interest
method.  The Company includes estimates for any residual value guarantee obligations under its leases in lease liabilities
recorded on its consolidated balance sheet.  

Right-of-use assets are included in other assets and property and equipment, net on the Company’s consolidated
balance sheet for operating and finance leases, respectively.  Obligations for lease payments are included in current portion
of lease liabilities and other liabilities on the Company’s consolidated balance sheet for both operating and finance leases.  

Contingent Consideration

The Company initially recorded a contingent consideration liability at fair value on the date of acquisition related
to  future  potential  payments  resulting  from  the  acquisition  of  Confluence  based  upon  significant  unobservable  inputs
including the achievement of development, regulatory and commercial milestones, as well as estimated future sales levels
and the discount rates applied to calculate the present value of the potential payments. Significant judgement was involved
in determining the appropriateness of these assumptions.  These assumptions are considered Level 3 inputs.  Revaluation of
the  contingent  consideration  liability  can  result  from  changes  to  one  or  more  of  these  assumptions.    The  Company
evaluates the fair value estimate of the contingent consideration liability on a quarterly basis with changes, if any, recorded
as income or expense in the consolidated statement of operations.

The fair value of contingent consideration is estimated using a probability-weighted expected payment model for

regulatory milestone payments and a Monte Carlo simulation model for commercial milestone and royalty payments and

86

Table of Contents

then  applying  a  risk-adjusted  discount  rate  to  calculate  the  present  value  of  the  potential  payments.    Significant
assumptions used in the Company’s estimates include the probability of achieving regulatory milestones and commencing
commercialization,  which  are  based  on  an  asset’s  current  stage  of  development  and  a  review  of  existing  clinical  data.
 Probability of success assumptions ranged between 10% and 40% at December 31, 2022.  Additionally, estimated future
sales levels and the risk-adjusted discount rate applied to the potential payments are also significant assumptions used in
calculating  the  fair  value.    The  discount  rate  ranged  between  9.8%  and  10.2%  depending  on  the  year  of  each  potential
payment.

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, 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,  which  is  typically  four  years.    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 measures the compensation expense of stock-based awards granted to consultants using the grant
date fair value of the award.  The Company recognizes compensation expense over the period during which services are
rendered by the consultant.

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.  Historically,  the  Company  estimated  expected  volatility  based  on  historical  volatility  of  a  set  of  peer  companies,
which are publicly traded. Starting in 2022, the Company estimated expected volatility based on its stock price's historical
volatility, as the Company determined that it had 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.

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.

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 that result from transactions
and  economic  events  other  than  those  with  stockholders.    Comprehensive  loss  is  primarily  comprised  of  net  loss  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 warrants and the assumed vesting of RSUs, 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.

88

Table of Contents

● 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.  

Concentration of Credit Risk and of Significant 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  is  dependent  on  third-party  manufacturers  to  supply  drug  product,  including  all  underlying
components, for its 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 or 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 has two reportable segments, therapeutics and contract research.  The therapeutics segment is focused on
identifying  and  developing  innovative  therapies  to  address  significant  unmet  needs  for  immuno-inflammatory  diseases.
  The  contract  research  segment  earns  revenue  from  the  provision  of  laboratory  services.    Contract  research  revenue  is
generally evidenced by contracts with clients which are on an agreed upon fixed-price, fee-for-service basis.  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.

Recently Issued 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 Company adopted this standard as of January 1, 2020, the impact of which
on its consolidated financial statements was not significant.  

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 Company adopted this standard as of January 1, 2020, the impact of which on its consolidated
financial statements was not significant.    

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  Company  adopted  this  standard  as  of  January  1,  2020,  the  impact  of  which  on  its
consolidated financial statements was not significant.

As of December 31, 2022 and 2021, the Company’s cash equivalents consisted of a money market fund, which
was valued based upon Level 1 inputs.  The Company’s marketable securities as of December 31, 2022 and 2021 consisted
of  commercial  paper,  and  corporate  debt,  asset-backed  and  U.S.  government  agency  debt  securities,  which  were  valued
based  upon  Level  2  inputs.    The  Company’s  marketable  securities  as  of  December  31,  2021  also  included  foreign
government agency debt securities, which were valued based upon Level 2 inputs. The Company’s marketable securities as
of December 31, 2022 also included U.S. government 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 are 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, 2022 and 2021, there were no transfers into or out of
Level 3.

The  increase  in  contingent  consideration  of  $4.7  million  during  the  year  ended  December  31,  2022  primarily

resulted from an increase in future sales level assumptions for zunsemetinib and the passage of time.

In  March  2020,  the  Company  entered  into  a  Loan  and  Security  Agreement  with  Silicon  Valley  Bank  (“SVB”).
 The Loan and Security Agreement provided for $11.0 million in term loans, of which the Company borrowed the entire
amount on March 30, 2020.  In connection with the Loan and Security Agreement, the Company issued to SVB a warrant
to purchase up to 460,251 shares of common stock (the “Warrant”) (see Note 8).  The proceeds of the Loan and Security
Agreement were allocated to the term loan and Warrant using a relative fair value approach.  

In  July  2021,  the  Company  repaid  in  full  the  $11.0  million  that  was  outstanding  under  the  Loan  and  Security
Agreement,  together  with  all  accrued  and  unpaid  interest  and  fees  as  of  the  payoff  date,  for  a  total  payment  of  $11.7
million.  Following this repayment, all of the Company’s obligations under the Loan and Security Agreement are deemed
to be terminated, except as set forth in the agreement.

8. Stockholders’ Equity

Preferred Stock

As of December 31, 2022 and 2021, the Company’s amended and restated certificate of incorporation authorized
the  Company  to  issue  10,000,000  shares  of  undesignated  preferred  stock.    There  were  no  shares  of  preferred  stock
outstanding as of December 31, 2022 and 2021.  

Common Stock

As of December 31, 2022 and 2021, the Company’s amended and restated certificate of incorporation authorized
the Company to issue 100,000,000 shares of $0.00001 par value common stock. There were 66,688,647 and 61,228,446
shares of common stock issued and outstanding as of December 31, 2022 and 2021, respectively.  

Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s
stockholders. Common stockholders are entitled to receive dividends, as may be declared by the board of directors, if any,
subject  to  any  preferential  dividend  rights  of  any  series  of  preferred  stock  that  may  be  outstanding.    No  dividends  have
been declared through December 31, 2022.  

Warrants

The Warrant issued to SVB in March 2020 had an initial exercise price of $0.956 per share, subject to adjustment
as provided in the Warrant. The Warrant became immediately exercisable in full upon the funding of the term loan facility.
 The Company assigned a fair value of $0.4 million to the Warrant using a Black-Scholes valuation methodology, and also
concluded that the Warrant was indexed to its own stock and therefore classified the Warrant as an equity instrument.  In
January 2021, SVB net exercised the Warrant in full, and the Company issued to SVB 388,119 shares of common stock.

Equity Purchase Agreement with Lincoln Park Capital Fund, LLC  

In  August  2020,  the  Company  entered  into  an  equity  purchase  agreement  (the  “Purchase  Agreement”)  with
Lincoln Park Capital Fund, LLC (“Lincoln Park”) which provided that, upon the terms and subject to the conditions and
limitations set forth therein, the Company could sell to Lincoln Park, at its discretion, up to $15.0 million of shares of its
common  stock  over  the  36-month  term  of  the  Purchase  Agreement.  Upon  execution  of  the  Purchase  Agreement,  the
Company issued 121,584 shares of its common stock to Lincoln Park as commitment shares in accordance with the closing
conditions contained within the Purchase Agreement. The commitment shares were valued using the closing price of the
Company’s  common  stock  on  the  effective  date  of  the  Purchase  Agreement  resulting  in  an  aggregate  fair  value  of  $0.3
million.  Through December 31, 2020, the Company sold 2,111,170 shares of its common stock to Lincoln Park under the
Purchase Agreement for net proceeds of $7.7 million.  The Company terminated the Purchase Agreement in January 2021
in connection with the public offering of common stock described below.  The Company did not sell any additional shares
prior to terminating the Purchase Agreement.

January 2021 Public Offering

In January 2021, the Company closed a public offering in which it sold 6,306,271 shares of common stock at a
price to the public of $17.50 per share, for aggregate gross proceeds of $110.4 million. The Company paid underwriting
discounts and commissions of $6.6 million, and also incurred expenses of $0.4 million in connection with the offering.  As
a  result,  the  net  offering  proceeds  received  by  the  Company,  after  deducting  underwriting  discounts,  commissions  and
offering expenses, were $103.3 million.

June 2021 Public Offering

In June 2021, the Company closed a public offering in which it sold 8,098,592 shares of common stock at a price
to  the  public  of  $17.75  per  share,  for  aggregate  gross  proceeds  of  $143.8  million.  The  Company  paid  underwriting
discounts and commissions of $8.6 million, and also incurred expenses of $0.3 million in connection with the offering.  As
a  result,  the  net  offering  proceeds  received  by  the  Company,  after  deducting  underwriting  discounts,  commissions  and
offering expenses, were $134.9 million.

Sales of Common Stock Pursuant to At-The-Market Facility

In  April  2022,  the  Company  sold  4,838,709  shares  of  its  common  stock  at  a  weighted  average  price  per  share
of  $15.50,  for  aggregate  gross  proceeds  of  $75.0  million,  pursuant  to  a  sales  agreement  with  SVB  Securities  LLC  and
Cantor  Fitzgerald  &  Co.,  as  sales  agents,  dated  May  20,  2021.    The  Company  paid  selling  commissions  and  other  fees
of $2.2 million in connection with the sale.

9. Stock-Based Awards

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 initial public offering in October 2015.  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, 2022, 3,095,380 shares remained available for grant under the 2015 Plan.  As of
January  1,  2023,  the  number  of  shares  of  common  stock  that  may  be  issued  under  the  2015  Plan  was  automatically
increased  by  2,667,545  shares.  The  Company  had  4,322,587  stock  options  and  1,520,730  RSUs  outstanding  as  of
December 31, 2022 under the 2015 Plan.

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-stockholder  approved  stock  plan  adopted  pursuant  to  the  “inducement  exception”
provided under Nasdaq listing rules.  The Company had 370,600 stock options outstanding as of December 31, 2022 under
the 2017 Inducement Plan.  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. 

2012 Equity Compensation Plan

Upon  the  2015  Plan  becoming  effective,  no  further  grants  can  be  made  under  the  2012  Plan.    The  Company
granted stock options to purchase a total of 1,140,524 shares under the 2012 Plan, of which 473,977 were outstanding as of
December 31, 2022.  Stock options granted under the 2012 Plan expire after ten years.

The  Company’s  potentially  dilutive  securities,  which  included  stock  options,  RSUs  and  warrants,  have  been
excluded  from  the  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 shares of common stock outstanding used to calculate both basic and diluted
net  loss  per  share  is  the  same.    The  following  table  presents  potential  shares  of  common  stock  excluded  from  the
calculation  of  diluted  net  loss  per  share  for  the  years  ended  December  31,  2022,  2021  and  2020.    All  share  amounts

As of December 31, 2022, the Company had federal and state net operating loss (“NOL”) carryforwards of $446.7
million and $477.9 million, respectively, which will begin to expire in 2032.  As of December 31, 2022, the Company also
had federal research and development tax credit carryforwards of $15.1 million which will begin to expire in 2032, and
state research and development tax credit carryforwards of $0.1 million which will begin to expire in 2022. The Company
also has $0.2 million of loss carryforwards in the United Kingdom which can be carried forward indefinitely. Utilization of
the  NOLs  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, 2021.  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 after December 31,
2021.    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,  2022  and  2021.    The  Company  evaluates  positive  and
negative evidence of its ability to realize deferred tax assets at each reporting period.

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 2020
to  the  present.   All  open  years  may  be  examined  to  the  extent  that  tax  credit  or  NOLs  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.

achievement of specified regulatory and commercial milestones set forth in the Confluence Agreement.  In addition, the
Company  agreed  to  pay  the  former  Confluence  equity  holders  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 to the payments described
above, if the Company sells, licenses or transfers any of the intellectual property acquired from Confluence pursuant to the
Confluence  Agreement  to  a  third  party,  the  Company  will  be  obligated  to  pay  the  former  Confluence  equity  holders  a
portion of any consideration received from such sale, license or transfer in specified circumstances.

As  of  December  31,  2022  and  December  31,  2021,  the  balance  of  the  Company’s  contingent  consideration

liability was $33.1 million and $28.4 million, respectively (see Note 3).  

License and Collaboration Agreement – 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  two  specified
JAK inhibitors.  In connection with an amendment of the agreement with Rigel in October 2019, the Company paid Rigel
an  amendment  fee  of  $1.5  million  during  the  year  ended  December  31,  2020.  The  Company  terminated  the  license  and
collaboration with Rigel effective as of April 2021.

15. 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 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  $0.5
million, $0.3 million and $0.4 million for the years ended December 31, 2022, 2021 and 2020, respectively.

16. Segment Information

The  Company  has  two  reportable  segments,  therapeutics  and  contract  research.    The  therapeutics  segment  is
focused on identifying and developing innovative therapies to address significant unmet needs for immuno-inflammatory
diseases.  The  contract  research  segment  earns  revenue  from  the  provision  of  laboratory  services.    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,  2022,  2021  and  2020  are

17. Legal Proceedings

Securities Class Action

On July 30, 2019, plaintiff Linda Rosi (“Rosi”) filed a putative class action complaint captioned Rosi v. Aclaris
Therapeutics, Inc., et al. in the U.S. District Court for the Southern District of New York against the Company and certain
of  its  executive  officers.  On  September  5,  2019,  an  additional  plaintiff,  Robert  Fulcher  (“Fulcher”),  filed  a  substantially
identical putative class action complaint captioned Fulcher v. Aclaris Therapeutics, Inc., et al. in the same court against the
same defendants. On November 6, 2019, the court consolidated the Rosi and Fulcher actions (together, the “Consolidated
Securities Action”) and appointed Fulcher “lead plaintiff” for the putative class. The parties signed and filed a settlement
agreement in July 2021. The court granted final approval of the settlement on December 9, 2021. As of

103

December 31, 2021, the Company’s financial obligation under the settlement was $2.7 million, which was within the limits
of its insurance coverage. The settlement was paid in January 2022.

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, 2022, 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 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 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,  2022,  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.

Management’s Report on Internal Control over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial
reporting, as defined in Rules 13a-15(f) and 15d-15(f) 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 our internal control over financial reporting was effective as of December 31, 2022 to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external
purposes  in  accordance  with  U.S.  GAAP.  Our  independent  registered  public  accounting  firm,  PricewaterhouseCoopers
LLP, has issued an audit report with respect to our internal control over financial reporting, which appears in Part II, Item 8
of this Annual Report.

Changes in Internal Control over Financial Reporting

There were no changes 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, 2022
that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations  on  Effectiveness  of  Disclosure  Controls  and  Procedures  and  Internal  Control  over  Financial

Reporting

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

Employment  Agreement  dated  January  12,  2022  (the  “Employment  Agreement”)).    For  the
avoidance of doubt, you and the Company hereby acknowledge and agree that you are not eligible
for  and  will  not  receive  the  severance  benefits  set  forth  in  Section  3.2.1  of  the  Employment

RE:  Separation Agreement and General Release

Dear Frank,   

Exhibit 10.18

This letter is intended to set forth the terms of your separation from employment with Aclaris Therapeutics,
Inc.  and  your  general  release  and  waiver  of  claims  in  favor  of  Aclaris  Therapeutics,  Inc.,  and  its  parents,
subsidiaries,  affiliates,  and  all  related  corporate  entities  and  partnerships,  and  their  current  or  former  officers,
directors, partners, shareholders, members, representatives, agents, employees, predecessors, successors, and assigns
(“Aclaris”).

The terms of this Separation Agreement and General Release (“Agreement”) are as follows, and you and
Aclaris, intending to be legally bound and for good and valuable consideration, each agree to all of the following
terms:

following the Retirement Date.

b. Amendment  to  Vesting  Schedule  of  Certain  Equity  Awards.  On  March  1,  2022,  you
were granted an option to purchase 155,200 shares of Aclaris’ common stock and a restricted stock unit award for

the contrary, Aclaris agrees that such awards will continue to vest during the term of the Consulting Agreement and
so long as you continue to provide Continuous Service (as defined in the Plan) to the Company.

c. Extended Exercise Period.  Contingent upon your signing the Supplemental Release as
detailed below, the Aclaris Board of Directors (the “Board”) or Compensation Committee will extend the exercise
period  governing  all  vested  shares  subject  to  your  options  (regardless  of  whether  you  enter  into  the  attached
Consulting Agreement and regardless of the term of such Consulting Agreement) so that your then-vested options at
the time of the expiration or earlier termination of the Consulting Agreement remain exercisable through the earlier
of  December  31,  2023  and  the  original  expiration  date  set  forth  in  the  stock  option  grant  notices  governing  your
options  (unless  terminated  earlier  in  accordance  with  the  terms  of  the  Plan).  By  signing  this  Agreement,  you

governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange
Commission, Congress, and any agency Inspector General, or making other disclosures that are protected under the

complaint,  or  investigation,  except  relating  to  information  provided  to  the  Securities  and  Exchange  Commission.

inducement of this Agreement.

8.

No  Admission.    This  Agreement  represents  a  full,  complete,  and  binding  compromise  of
claims and shall not be construed as an admission by any party of any liability or of any contention or allegation
made by the other party.

released herein.  Notwithstanding the broad scope of the general release above in Paragraph 7, this Agreement is not
intended  to  bar  any  claims  that,  as  a  matter  of  law,  whether  by  statute  or  otherwise,  may  not  be  waived,  such  as
claims for workers’ compensation benefits, unemployment insurance benefits and any challenge to the validity of
your  general  release  of  claims  under  the  ADEA  as  set  forth  in  this  Agreement.    Nothing  in  this  Agreement  is
intended to interfere with your right to file a charge or participate in an administrative investigation or proceeding;
any claims by you (or on your behalf) for personal relief including, without limitation, reinstatement, or monetary
damages, would be barred.  You specifically understand that, in the event a complaint or charge is filed, you shall
personally  have  no  right  to  any  relief  whatsoever  against  Aclaris,  including  having  no  right  to  reinstatement,
monetary damages or attorneys’ fees.

Paragraphs 4 through 6 hereof, the benefits contained in Paragraphs 2(a)-(c) of this Agreement shall be forfeited and
Aclaris shall have no obligation to pay any amount other than your final salary as of the Retirement Date and any
other  amounts  that  may  be  required  by  law  to  be  paid.    In  addition,  if  you  breach  this  Agreement  after  payment

against Aclaris.

18.

Severability.  If any provision of this Agreement is held to be invalid or unenforceable by a
court of competent jurisdiction or an arbitrator, that provision will be deemed to be restated to reflect as nearly as

instance.  Any waiver of any provision hereof shall be limited to the specific circumstances to which it applies and

SUPPLEMENTAL RELEASE OF CLAIMS

I, Frank Ruffo, hereby acknowledge and affirm that I executed a Separation Agreement and General Release with
Aclaris  Therapeutics,  Inc.  ("Aclaris"),  dated  December  ___,  2022  (the  "Agreement").    Pursuant  to  that

Aclaris,  which  extends  the  release  of  claims  set  forth  in  the  Agreement,  in  order  to  receive  the  consideration  set
forth in Paragraph 2 of the Agreement.  I, therefore, agree as follows:

1. An  unexecuted  copy  of  this  Supplemental  Release  was  attached  to  the  Agreement.    I  hereby  certify  and
acknowledge that I received this Supplemental Release at least twenty-one (21) days before I was required to
sign it.

2. General Release.

a)

In consideration of the benefits described in Paragraph 2 of the Agreement, I hereby generally release and
discharge  Aclaris  from  any  and  all  suits,  causes  of  action,  complaints,  charges,  obligations,  demands,  or
claims of any kind, whether in law or in equity, direct or indirect, known or unknown (hereinafter “claims”),
which  I  ever  had  or  now  have  against  Aclaris  arising  out  of  or  relating  to  any  matter,  thing  or  event
occurring up to and including the date of this Supplemental Release.  I also release Aclaris from any and all
claims for wrongful discharge, defamation, unfair treatment, violation of public policy, breach of express or
implied contract, intentional or negligent infliction of emotional distress, any and all tort claims or any other
claim related to my employment with Aclaris or the termination of that employment for any and all reasons,
up to and including the date of this Agreement.  I specifically release Aclaris from any claim relating to or
arising out of my employment with or termination of employment from Aclaris, including, but not limited

Discrimination in Employment Act, including the Older Workers Benefits Protection Act (“ADEA”), which

of 1988, 29 U.S.C. § 210l, et seq.; and any and all other federal, state or local laws or regulations prohibiting
employment discrimination or which otherwise regulate employment terms and conditions, except as such
release is limited by applicable laws.  This is a general release and covers claims that I know about presently
and  those  that  I  may  not  know  about  up  through  the  date  of  this  Supplemental  Release.    This  release
specifically includes any and all claims for attorney’s fees and costs which I incur for any reason arising out
of or relating to any or all matters covered by this Supplemental Release.

I hereby represent and warrant that I have no knowledge of any acts or omissions by Aclaris or any other

employment laws administered by the Equal Employment Opportunity Commission or any comparable state
or local fair employment practices agencies, or of the National Labor Relations Act,  29 U.S.C. § 157, or of

 Nothing in this Supplemental Release should be construed as prohibiting me from responding to inquiries
from  or  otherwise  reporting  possible  violations  of  federal  or  state  law  or  regulation  to  any  governmental
agency  or  entity,  including  but  not  limited  to  the  Department  of  Justice,  the  Securities  and  Exchange
Commission, Congress, and any agency Inspector General, or making other disclosures that are protected
under  the  whistleblower  provisions  of  federal  or  state  law  or  regulation.    However,  by  signing  this

participate  in  an  administrative  investigation  or  proceeding;  any  claims  by  me  (or  on  my  behalf)  for
personal  relief  including,  without  limitation,  reinstatement,  or  monetary  damages,  would  be  barred.    I
specifically understand that, in the event a complaint or charge is filed, I shall personally have no right to
any  relief  whatsoever  against  Aclaris,  including  having  no  right  to  reinstatement,  monetary  damages  or
attorneys’ fees.

Eastern Standard Time on the seventh (7th) day following the day I sign this Supplemental Release.  If the last

to  be  the  next  business  day.    If  I  revoke  this  Supplemental  Release  in  this  manner,  the  Supplemental  Release
shall  automatically  be  null  and  void  and  I  understand  that  I  will  not  be  entitled  to  the  benefits  described  in

2.1.
Intellectual Property.  Consultant  agrees  that  any  information,  including,  but  not  limited
to, discoveries, inventions, copyrights, design rights, patents, innovations, suggestions, know-how,
ideas, manuscripts, publications and reports (including all drafts and versions of such manuscripts,

the sole property of the Company.  Consultant further acknowledges that (a) the Company owns,
retains, and has exclusive right, title and interest in and to such Company Intellectual Property, (b)
Consultant may not use such Company Intellectual Property without the Company’s prior written
consent  and  (c)  in  no  event  shall  Consultant  (i)  publish  or  publicly  present  such  Company

2.2. Works  for  Hire;  Assignment.  Consultant  acknowledges  that  all  work  emanating  from
Consultant’s performance of the Services hereunder that falls within a category of “work made for
hire,” as that term is defined in the U.S. Copyright Act, shall be considered “work made for hire”
(collectively,  “Work  Made  For  Hire”),  with  all  copyrights  in  such  Work  Made  For  Hire  being

Consultant  hereby  assigns  to  the  Company  all  right,  title  and  interest,  including  any  present  or
future interest, any associated patent, copyright and any other intellectual property or proprietary
right, in and to all Company Intellectual Property. This assignment includes, without limitation, all

distribute copies of the work to the public by sale, transfer of ownership, rental, lease, or lending,
perform the work publicly or display the work publicly.

Further Assurances.  

2.3.1.

In furtherance of this Article II, Consultant, at the Company’s request and without
any  additional  consideration,  shall  promptly  execute,  acknowledge,  prepare  and  deliver  to  the
Company  and/  or  its  attorneys  any  and  all  instruments  and  other  documents,  including  United
States  and  foreign  patent  applications,  applications  for  securing,  protecting  or  registering  any
property  rights  embraced  within  this  Agreement,  powers  of  attorney,  assignments,  oaths  or
affirmations, supplemental oaths and sworn statements, and do any and all other lawful acts which,
in the judgment of the Company or its attorneys, may be necessary or desirable to document the
aforesaid assignment of Company Intellectual Property, vest in, register for, secure for, or maintain
for the benefit of, the Company, adequate patent and other property rights in the United States and

2

all foreign countries with respect to any and all Company Intellectual Property. Consultant further

power  to  do  so,  any  such  instrument  or  other  document  shall  continue  after  the  expiration  or
termination  of  this  Agreement.  If  the  Company  is  unable  for  any  reason  to  secure  Consultant’s
signature  to  apply  for  or  to  pursue  any  application  for  any  United  States  or  foreign  patent,
trademark,  copyright  or  other  registration  covering  Company  Intellectual  Property  owned  by  or
assigned  to  the  Company  as  stated  above,  then  Consultant  hereby  irrevocably  designates  and
appoints  the  Company  and  its  duly  authorized  officers  and  agents  as  Consultant’s  agent  and
attorney in fact, coupled with an interest, to act for and on Consultant’s behalf and stead to execute
and file any such applications and to do all other lawfully permitted acts to further the prosecution
and  issuance  of  patent,  trademark,  copyright  or  other  registrations  thereon  with  the  same  legal
force and effect as if executed by Consultant.

Intellectual  Property,  Consultant  shall  ensure  that  Consultant’s  performance  of  the  Services  is

third party.  

ARTICLE III  – INDEMNIFICATION

3.1.

reasonably  acceptable  to  the  Company)  and  at  Consultant’s  sole  expense.    Such  Company
Indemnitee shall cooperate in the defense in all reasonable respects at Consultant’s sole cost and
expense.    Such  Company  Indemnitee  shall  be  entitled  to  retain  its  own  legal  counsel,  at  such
Company  Indemnitee’s  own  expense,  to  participate  in  the  defense  of  the  Claim  in  an  advisory
capacity.

3.2.
Indemnification  by  the  Company.    The  Company  shall  indemnify  and  hold  harmless
Consultant  and  its  directors,  officers,  employees,  shareholders  and  agents  (each,  a  “Consultant

at the Company’s sole cost and expense.  Such Consultant Indemnitee shall be entitled to retain its

the Claim in an advisory capacity.

ARTICLE IV  – CONFIDENTIALITY; NON-SOLICITATION

4.1.
Confidential  Information.    As  used  herein,  “Confidential  Information”  means  all
Company Intellectual Property and any of the Company’s proprietary or confidential information,
technical  data,  trade  secrets,  know-how  or  other  business  information  that  is  disclosed  to
Consultant  by  the  Company  or  its  employees  or  agents,  either  directly  or  indirectly,  in  writing,
orally  or  by  drawings  or  inspection  of  documents  or  other  tangible  property.    The  term
“Confidential  Information”  excludes  any  information  that  is  or  becomes  a  matter  of  public
knowledge through no act or omission on the part of Consultant.

4.2.
Company’s  Customers  and  Marking.    Consultant  recognizes  that  the  Company  has

information and materials and to use them only for certain limited purposes.  Consultant agrees, at
all times during the term of this Agreement and thereafter, to treat such information and materials
as  Confidential  Information  of  the  Company  as  set  forth  herein.    The  Confidential  Information
does  not  need  to  be  marked  as  “Confidential”  or  with  any  other  term  or  marking,  although
Consultant shall use commercially reasonable efforts to mark all Confidential Information created
or modified by Consultant, or in Consultant’s possession, as “Confidential” or such other term or
marking specified by the Company.

Agreement  and  thereafter,  to  hold  in  confidence,  not  to  use  for  any  purposes  other  than
Consultant’s performance of the Services, and not to disclose to any person or entity without prior
written consent of a duly authorized representative of the Company, any Confidential Information
of  the  Company.    Consultant’s  confidentiality,  non-use  and  non-disclosure  obligations  under  this
Agreement do not amend or abrogate in any manner Consultant’s continuing duties under any prior
agreement  between  Consultant  and  the  Company,  including  but  not  limited  to  under  the
Confidentiality and Invention Rights and Non-Solicitation Agreement between Consultant and the
Company.

4.4.
Restrictions.  Consultant agrees that in performing the Services, Consultant will not use,
incorporate into any Company Intellectual Property, or disclose to the Company, any proprietary or
confidential information or trade secrets of any third person or entity.

4.5.
period of twenty-four (24) months thereafter, Consultant shall not for any reason, either directly

4

or  indirectly,  on  Consultant’s  own  behalf  or  in  the  service  or  on  behalf  of  others,  (a)  solicit  or
recruit any person who is employed or engaged by the Company, whether or not such person is a
full-time  employee  of  the  Company,  (b)  employ  or  retain  any  such  person  or  (c)  attempt  to
persuade  any  such  person  to  terminate  such  person’s  employment  with  or  engagement  by  the
Company.

breach  of  this  Agreement  by  Consultant  or  for  such  other  good  cause  as  the  Company  shall
determine  in  its  reasonable  discretion.    The  Company  shall  provide  prior  written  notice  to
Consultant  detailing  the  alleged  breach  or  cause  and  demanding  a  cure.    If,  after  thirty  (30)
calendar  days  following  such  written  notice,  Consultant  has  not  cured  the  breach,  then  the

ARTICLE VII  – MISCELLANEOUS

7.1.
Independent Contractor Status.  For purposes of this Agreement and the Services to be
performed,  Consultant  shall  not  be  considered  a  partner,  co-venturer,  agent,  employee  or
representative of the Company, but shall remain in all respects an independent contractor.  Neither
party  shall  have  any  right  or  authority  to  make  or  undertake  any  promise,  warranty  or
representation, to execute any contract, or otherwise to assume any obligation or responsibility in
the  name  of  or  on  behalf  of  the  other  party.    In  addition,  neither  Consultant  nor  Consultant’s
employees, agents or contractors, if any, will be entitled to participate in or receive any benefit or
right  as  an  employee  of  the  Company  under  any  Company  employee  benefit  or  welfare  plan,
including, without limitation, employee insurance, pension, savings or security plans, as a result of
entering into this Agreement or performing the Services and Consultant hereby waives any and all
rights to such participation.  Notwithstanding the foregoing, this Agreement does not amend or

6

abrogate in any manner any benefit continuation or conversion rights provided by the provision of
a  benefit  plan  or  by  law  arising  out  of  Consultant’s  previous  employment  relationship  with  the
Company.

7.2.

Arbitration and Equitable Relief.

7.2.1. Arbitration.  Except as provided in Section 7.2.2 below, each party agrees that any
dispute or controversy arising out of or relating to the interpretation, construction, performance or
breach of this Agreement, shall be settled by arbitration to be held in Philadelphia, Pennsylvania,
before  a  single  arbitrator  and  in  accordance  with  the  Commercial  Arbitration  Rules  of  the
American  Arbitration  Association  then  in  effect.    Each  party  irrevocably  and  unconditionally
consents to the jurisdiction of any such proceeding and waives any objection that it may have to
personal  jurisdiction  or  the  laying  of  venue  of  any  such  proceeding.    The  parties  will  cooperate
with  each  other  in  causing  the  arbitration  to  be  held  in  as  efficient  and  expeditious  a  manner  as
practicable.  If the parties are unable to appoint a mutually acceptable arbitrator within thirty (30)
calendar  days  after  a  party  gives  written  notice  to  the  other  requesting  resolution  of  a  dispute  in
accordance  with  the  provisions  of  this  Section 7.2.1,  the  American  Arbitration  Association  shall
appoint the arbitrator in accordance with such Commercial Arbitration Rules.  The arbitrator may
grant injunctions or other relief in such dispute or controversy.  The decision of the arbitrator shall
be final, conclusive and binding on the parties to the arbitration.  Judgment may be entered on the
arbitrator’s decision in any court having jurisdiction.  The Company and Consultant shall each pay
one-half of the costs and expenses of such arbitration, and each party shall separately pay the fees
and expenses of its own counsel.  Nothing herein shall prevent the parties from settling any dispute
by mutual agreement at any time.

7.2.2. Equitable Remedies.  Consultant agrees that it would be impossible or inadequate to
measure  and  calculate  the  Company’s  damages  from  any  breach  of  the  covenants  set  forth  in
Articles  II  and  IV,  and  Section  5.4  of  this  Agreement.    Accordingly,  Consultant  agrees  that,  if
Consultant breaches or threatens to breach any of such covenants, the Company will have available
to it, in addition to any other rights or remedies, the right to obtain an injunction from a court of
competent jurisdiction restraining such breach or threatened breach and to specific performance of
any  such  provision  of  this  Agreement.    Consultant  further  agrees  that  no  bond  or  other  security
shall be required in obtaining such equitable relief, and Consultant hereby consents to the issuance
of such injunction and to the ordering of such specific performance. With respect to the matters set
forth  in  this  Section  7.2.2,  the  parties  irrevocably  consent  to  the  exclusive  jurisdiction  of  the
federal and state courts of the Commonwealth of Pennsylvania.

7.3.
Force  Majeure.    Neither  party  shall  be  liable  for  failure  of  or  delay  in  performing  any
obligations  set  forth  in  this  Agreement,  and  neither  party  shall  be  deemed  in  breach  of  its
obligations  under  this  Agreement,  if  and  to  the  extent  such  failure  or  delay  is  due  to  natural
disasters  or  any  other  causes  reasonably  beyond  the  control  of  such  party  (a  “Force  Majeure
Event”); provided that the party affected by such circumstances (a) resumes performance as soon
as possible following the end of the occurrence causing delay or failure of performance and (b) is
reasonably diligent during the Force Majeure Event in avoiding further delay or nonperformance.
 In the event of a Force Majeure Event, the party so affected shall give prompt written notice to the
other party, stating the period of time the Force Majeure Event is expected to continue.

7

7.4.
Entire  Agreement;  Amendment.    This  Agreement  is  being  entered  into  as  part  of  the
Separation  Agreement  between  Consultant  and  the  Company  and  will  only  become  effective
following  execution  and  non-revocation  by  Consultant  of  the  Separation  Agreement  and  the
Supplemental Release of Claims attached thereto.  This Agreement is the sole agreement between
the Company and Consultant pertaining to the subject matter herein, and shall supersede all prior
agreements  and  understandings  between  the  Company  and  Consultant  with  respect  thereto,
whether  oral,  written  or  otherwise,  excluding  any  confidentiality  agreement  between  the  parties.
No modification to or waiver of any provision of this Agreement shall be binding unless in writing
and  signed  by  both  Consultant  and  the  Company.    The  parties  have  entered  into  separate
agreements  related  to  Consultant’s  previous  employment  relationship  with  Aclaris  Therapeutics,
Inc.  These separate agreements govern the previous employment relationship between Consultant
and  Aclaris  Therapeutics,  Inc.,  have  or  may  have  provisions  that  survive  termination  of
Consultant’s relationship with the Company under this Agreement, may be amended or superseded
without regard to this Agreement, and are enforceable according to their terms without regard to
the enforcement provision of this Agreement.  

7.5.
Assignment.  All of the terms and provisions of this Agreement shall be binding upon and
inure to the benefit of and be enforceable by the respective heirs, executors, administrators, legal
representatives,  successors  and  assigns  of  the  parties  hereto,  except  that  the  duties  and
responsibilities  of  Consultant’s  hereunder  are  of  a  personal  nature  and  shall  not  be  assignable  or
delegable in whole or in part by Consultant. The Company may assign this Agreement, in whole or
in part, to a third party without the prior written consent of Consultant: (a) in connection with the
sale, transfer or license of all or substantially all of the assets of Company or the line of business or
product to which this Agreement or the Services relates; (b) to the successor entity or acquirer in
the event of the merger, consolidation or change of control of the Company; or (c) to any affiliate
of the Company. Any subsequent assignee purchaser or transferee shall be bound by the terms of
this Agreement.

7.6. Governing Law.  This Agreement shall be governed by and interpreted in accordance with
the  laws  of  the  Commonwealth  of  Pennsylvania,  without  giving  effect  to  any  conflict  of  laws
provisions.

7.7.
Notices.   All  notices,  requests,  demands,  waivers  and  other  communications  required  or
permitted  to  be  given  under  this  Agreement  shall  be  in  writing  and  may  be  given  by  any  of  the
following  methods:  (a)  personal  delivery,  (b)  facsimile  transmission,  (c)  registered  or  certified
mail,  postage  prepaid,  return  receipt  requested,  (d)  air  courier  service,  or  (e)  electronic  mail.
 Notices shall be sent to the appropriate party as provided below (or at such other address for such
party  as  shall  be  specified  by  notice  given  hereunder).   Any  such  notice  shall  be  deemed  to  be
given and received on the day on which it was delivered or transmitted, or if mailed, on the date on
which it was received.

upon  execution  of  this  Agreement  by  means  of  such  electronic  signatures  or  maintenance  of  the
executed agreement electronically.

7.9.
Severability.  If any provision of this Agreement or application thereof to anyone or under
any circumstances is adjudicated to be invalid or unenforceable in any jurisdiction, such invalidity
or unenforceability shall not affect any other provision or application of this Agreement which can
be  given  effect  without  the  invalid  or  unenforceable  provision  or  application,  and  shall  not
invalidate or render unenforceable such provision or application in any other jurisdiction.

which is hereby superseded by this Employment Agreement;

WHEREAS,  Employer  and  Executive  desire  to  formalize  the  terms  and  conditions  of

Executive’s employment with Employer; and

WHEREAS,  this  Employment  Agreement  has  been  duly  approved  and  its  execution  has

been duly authorized by the Board of Directors of Employer (the “Board”).

NOW, THEREFORE, Employer and Executive hereby agree as follows:

SECTION 1. EMPLOYMENT

1.1

General.  Employer  hereby  agrees  to  employ  Executive  in  the  capacity  of  Chief
Executive  Officer  (“CEO”)  and  President,  and  Executive  hereby  accepts  such  continued
employment upon the terms and subject to the conditions herein contained.

1.2

Authority  and  Duties.  Executive  shall  have  full  responsibility  as  the  CEO  and
President  of  Employer  and  all  authority  normally  accorded  to  such  position.  Executive  agrees  to
perform such duties and responsibilities commensurate with the positions of CEO and President as
may reasonably be determined by the Board.

1.2.1  Reporting.  During  Executive’s  employment  with  Employer,  Executive  will

report directly to, and take direction from, the Board.

1.2.2 Time to Be Devoted to Employment. During Executive’s Employment with
Employer, Executive shall diligently devote his efforts, business time, attention and energies to the
business of Employer and will not, while employed by Employer, undertake or engage in any other
interfere  with  Executive’s
employment,  occupation  or  business  enterprise 
responsibilities and the performance of Executive’s duties hereunder except for (i) reasonable time
devoted  to  volunteer  services  for  or  on  behalf  of  such  religious,  educational,  non-profit  and/or
other  charitable  organization  as  Executive  may  wish  to  serve,  (ii)  reasonable  time  devoted  to
activities in the non-profit and business communities consistent with Executive’s duties; and (iii)
reasonable time devoted to service as a member of the board of directors of the entities listed on
Exhibit A or as otherwise permitted pursuant to Section 1.3. This restriction shall not, however,

that  would 

1

preclude Executive (x) from owning less than one percent (1%) of the total outstanding shares of a
publicly  traded  company,  or  (y)  from  employment  or  service  in  any  capacity  with  Affiliates  of
Employer.  As used in this Employment Agreement, “Affiliates” means an entity under common
management or control with Employer.

1.3

Other  Responsibilities.  Notwithstanding  Section  1.2.2  above,  Executive  will  not
engage in any other for-profit business, profession or occupation, including as a member of a board
of  directors  of  any  third  party,  for  compensation  which  would  materially  conflict  or  materially
interfere with the rendition of services hereunder, without the prior written consent of the Board,
which  shall  not  be  unreasonably  withheld.   Any  uncertainty  as  to  whether  such  a  conflict  exists
will  be  raised  by  Executive  for  determination  by  the  Board,  acting  reasonably.  The  Board
acknowledges that Executive has ongoing participation in other private and public businesses that
have been disclosed by Executive and are listed on Exhibit A and that such participation does not,
in  any  way,  conflict  with  his  role  at  Employer.    Except  for  the  businesses  listed  on  Exhibit  A,
which  have  already  been  approved,  Executive  agrees  to  disclose  to  the  Board  and  receive  prior
written consent from the Board to participate as a director, with any competing company whether it
is  a  private  or  public  company.  Executive  further  agrees  to  disclose  any  other  director  positions
with  any  other  company  that  may  materially  affect  his  ability  to  perform  his  duties  and
responsibilities  under  this  Employment  Agreement.  Notwithstanding  the  above,  nothing  herein
shall limit or preclude Executive from managing any passive investments made by Executive.

1.4

Location  of  Employment.  Executive’s  principal  place  of  employment  during  his
employment with Employer shall be Executive’s primary residence (or other remote work location)
or such other location as Employer and Executive shall agree; provided however, that from time to
time  Executive  may  be  required  to  travel  to  Employer’s  offices,  including  Employer’s  principal
executive office currently located in Wayne, Pennsylvania.

SECTION 2.  COMPENSATION AND BENEFITS

2.1

Salary. Employer will pay to Executive an annual base salary of $600,000, payable
subject  to  standard  federal  and  state  payroll  withholding  requirements  in  accordance  with  the
regular payroll practices of Employer (“Base Salary”). The annual Base Salary may be increased
(but  not  decreased)  during  the  term  of  this  Employment  Agreement  by  the  Board  in  its  sole
discretion.

2.2

Additional  Compensation.  In  addition  to  the  salary  set  forth  in  Section  2.1,
Executive shall be entitled to receive a cash bonus in accordance with the terms of this Section 2.2.
For each fiscal year of Employer, beginning January 1, during the Amended Employment Term (as
defined in Section 2.4 hereof), Executive shall be eligible to receive a cash bonus based on (i) the
“Annual  Bonus  Expectancy  Amount,”  which  shall  be  an  amount  equal  to  55%  of  Executive’s
Base  Salary  for  the  applicable  fiscal  year,  and  (ii)  Executive’s  attainment  of  performance  targets
and other reasonable criteria established by the Board, to the extent possible, by the end of the first
month  of  such  fiscal  year.  Depending  on  the  targets  and  criteria  which  are  achieved  or  met,  the
amount  of  the  cash  bonus  actually  payable  to  Executive  for  each  fiscal  year  will  be  an  amount
from  zero  to  and  including  the  Annual  Bonus  Expectancy  Amount.  Any  cash  bonus  amount
payable  pursuant  to  this  Section  2.2  shall  be  paid  to  Executive  as  soon  as  practicable,  but  in  no
event later than two and one-half (2 1/2) months, following the end of the fiscal year to

2

which it relates. For the avoidance of doubt, Executive does not have to be employed by Employer
on the date such bonus is approved or paid by Employer to receive such bonus.

2.3

Executive Benefits. In addition to the salary and additional compensation set forth
in  Sections  2.1  and  2.2,  Executive  shall  also  be  entitled  to  the  following  benefits  during
Executive’s employment hereunder:

2.3.1  Expenses.  Employer  will  promptly  reimburse  Executive  for  expenses  he
reasonably incurs in connection with the performance of his duties (including business travel and
entertainment expenses), in accordance with Employer’s standard expense reimbursement policy,
as the same may be modified by Employer from time to time; provided, however, that Executive
has provided Employer with documentation of such expenses in accordance with the Employer’s
expense  reimbursement  policies  and  applicable  tax  requirements.  For  the  avoidance  of  doubt,  to
the extent that any reimbursements payable to Executive are subject to the provisions of Section
409A  of  the  Internal  Revenue  Code  of  1986,  as  amended  (the  “Code”):  (a)  any  such
reimbursements will be paid no later than December 31 of the year following the year in which the
expense  was  incurred,  (b)  the  amount  of  expenses  reimbursed  in  one  year  will  not  affect  the
amount  eligible  for  reimbursement  in  any  subsequent  year,  and  (c)  the  right  to  reimbursement
under  this  Employment  Agreement  will  not  be  subject  to  liquidation  or  exchange  for  another
benefit.

2.3.2  Employer  Plans.    Executive  will  be  eligible  to  participate  on  the  same
basis  as  similarly  situated  employees  in  Employer’s  employee  benefit  plans  and  programs,  as
they  may  be  interpreted,  adopted,  revised  or  deleted  from  time  to  time  in  Employer’s  sole
discretion,  subject  to  and  on  a  basis  consistent  with  the  terms,  conditions  and  overall
administration  of  such  plans  and  programs.  All  matters  of  eligibility  for  coverage  or  benefits
under  any  benefit  plan  shall  be  determined  in  accordance  with  the  provisions  of  such  plan.
Employer retains the unilateral right to amend, modify or terminate any of its employee benefit
plans and programs at any time.

2.3.3 Vacation. Executive shall be eligible for paid vacation leave (not including
regular  holidays)  consistent  with  the  needs  of  the  business.  Vacation  must  be  scheduled  at
those times convenient to Employer’s business as reasonably determined by the Board.

2.3.4  Coverage.  Nothing  in  this  Employment  Agreement  shall  prevent  Executive
from  participating  in  any  other  compensation  plan  or  benefit  plan  made  available  to  him  by
Employer.

2.3.5 Withholding. All compensation shall be subject to withholding of taxes and

deductions of other amounts as may be required by law.

2.4       Employment Term. Unless earlier terminated pursuant to Section 3.1, Executive’s
employment by Employer pursuant to this Employment Agreement shall continue until the second
anniversary  of  the  Agreement  Effective  Date  (the  “Amended  Initial  Term”).  Thereafter,  this
Employment Agreement shall be automatically renewed for successive one (1) year periods (any
subsequent  employment  period  being  referred  to  herein  as  the  “Amended  Renewal  Term”,  and
together with the Amended Initial Term, the “Amended Employment Term”); provided, however,

3

that  either  party  may  elect  to  not  renew  this  Employment  Agreement  by  written  notice  to  such
effect  delivered  to  the  other  party  at  least  ninety  (90)  days  prior  to  expiration  of  the  Amended
Initial Term or the Amended Renewal Term.

SECTION 3.  TERMINATION OF EMPLOYMENT

3.1

Events of Termination. Executive’s employment with Employer will terminate

upon the occurrence of any one or more of the following events:

3.1.1  Death.  In  the  event  of  Executive’s  death,  Executive’s  employment  will

terminate on the date of death.

3.1.2  Disability.  In  the  event  of  Executive’s  Disability  (as  hereinafter  defined),
Employer  will  have  the  option  to  terminate  Executive’s  employment  by  giving  a  notice  of
termination to Executive. The notice of termination shall specify the date of termination, which
date shall not be earlier than thirty (30) calendar days after the notice of termination is given. For
purposes  of  this  Employment  Agreement,  “Disability”  has  the  meaning  set  forth  in  Employer’s
long term disability plan.  

3.1.3 Termination by Employer for Cause. Employer may, at its option, terminate
Executive’s  employment  for  Cause  (as  hereinafter  defined)  by  unilateral  action  of  the  Board  of
Directors  upon  giving  a  notice  of  termination  to  Executive.  “Cause”  shall  mean  (i)  Executive’s
conviction of, or guilty plea to, a felony (other than traffic violations); (ii) any act(s) or omission(s)
by  Executive  which  constitutes  gross  negligence  or  a  material  breach  of  Executive’s  duty  of
loyalty;  (iii)  any  material  breach  by  Executive  of  Employer’s  personnel  policies;  (iv)  refusal  to
follow or implement a clear and reasonable directive of Employer; (v) breach of fiduciary duty; or
(vi)  a  material  violation  or  breach  by  Executive  of  this  Employment  Agreement  (other  than  an
event described in the foregoing clauses) or any other agreement between the parties.

3.1.4  Without  Cause  By  Employer.  Employer  may,  at  its  option,  terminate
Executive’s  employment  for  any  reason  whatsoever  (other  than  for  the  other  reasons  set  forth
above  in  this  Section  3.1  that  would  constitute  “Cause”  to  terminate)  by  giving  a  notice  of
termination to Executive, and Executive’s employment shall terminate on the later of the date the
notice of termination is given or the date set forth in such notice of termination.

3.1.5 By Executive. Executive may, at any time, terminate Executive’s employment
for any reason whatsoever by giving a notice of termination to Employer. Executive’s employment
shall terminate on the earlier of (i) thirty (30) calendar days after the date of receipt by Employer
of the notice of termination or (ii) such earlier date as the Employer and Executive shall agree.

this
3.1.6  Termination  Upon  Non-Renewal.  Either  party  may 
Employment  Agreement  and  Executive’s  employment  hereunder  by  providing  the  other  party
notice  in  accordance  with  Section  2.4  above,  in  which  case  this  Employment  Agreement  and
Executive’s employment hereunder shall terminate on the last date of the Amended Initial Term or
the Amended Renewal Term, as the case may be. For the avoidance of doubt, Executive shall

terminate 

4

continue  to  be  employed  by  Employer,  on  the  same  terms  and  conditions  as  set  forth  in  this
Employment Agreement during the ninety (90)-day notice period provided by either party to the
other  party  in  accordance  with  Section  2.4  above,  unless,  Employer,  in  its  sole  discretion
determines  that  it  does  not  want  Executive  to  continue  to  work  for  Employer,  in  any  capacity,
during  such  notice  period.  In  such  event,  Employer  shall  pay  Executive  all  compensation  in
accordance with Section 3.2.3.

3.1.7  For  Good  Reason  by  Executive.  Executive  may,  at  his  option,  terminate
Executive’s employment for “Good Reason” by giving a notice of termination to Employer in the
event that, in the absence of events that would support a termination of Executive for Cause:

(i)

there  is  a  material  failure  of  Employer  (or  successor  employer)  to  pay
Executive’s  salary  or  additional  compensation  or  benefits  hereunder  in  accordance  with  this
Employment Agreement;

(ii)

Executive’s  Base  Salary  is  materially  decreased  without  his  prior  written

consent;

(iii)

Executive  is  assigned  duties  materially  inconsistent  with  his  title  and  the

responsibilities set forth in Executive’s job description, without Executive’s prior written consent;

(iv)

Executive’s place of employment is changed to a location that is greater than
fifty (50) miles from Executive’s current place of employment (disregarding for this purpose any
remote work arrangements); or

(v)

any  other  material  violation  or  breach  by  Employer  of  this  Employment
Agreement.  Notwithstanding  the  foregoing,  none  of  the  events  described  in  clauses  (i)  through
(iv) above shall constitute Good Reason unless Executive shall have notified Employer in writing
describing  the  event  which  constitute  Good  Reason  within  thirty  (30)  days  after  Executive  first
becomes aware of such event and then only if Employer shall have failed to reasonably cure such
events,  if  curable,  within  thirty  (30)  days  after  Employer’s  receipt  of  such  written  notice  and
Executive elects to terminate his employment as a result within thirty (30) days following the end
of such thirty (30) day period (assuming, for the avoidance of doubt, that Employer does not elect
to cure).

3.2

Certain  Obligations  of  Employer  Following  Termination  of  Executive’s
Employment.  Following  the  termination  of  Executive’s  employment  under  the  circumstances
described  below,  Employer  will  pay  to  Executive,  subject  to  standard  federal  and  state  payroll
withholding  requirements  and  in  accordance  with  its  regular  payroll  practices,  the  following
compensation  and  provide  the  following  benefits  (provided  that  the  continuing  payments  of
Executive’s  then-current  Base  Salary,  as  described  below,  shall  occur  no  less  frequently  than
monthly):

3.2.1  Death;  Disability;  Termination  by  Employer  Without  Cause  or  by
Executive  for  Good  Reason.  In  the  event  that  Executive’s  employment  is  terminated  by
Employer  pursuant  to  Section  3.1.1  (“Death”),  Section  3.1.2  (“Disability”),  Section  3.1.4
(“Without Cause by Employer”) or by Executive pursuant to Section 3.1.7 (“Termination by

5

Executive for Good Reason”) hereof, and Executive, or his estate, as the case may be, executes
and does not revoke a separation agreement containing a release upon such termination, in a form
provided  by  the  Employer,  of  any  and  all  claims  against  Employer  and  all  related  parties  with
respect  to  all  matters  arising  out  of  Executive’s  employment  by  Employer,  or  the  termination
thereof (the “Release”) in accordance with Section 3.7, Executive, or his estate, as the case may
be, shall be entitled to the following payments and benefits, which payments and benefits shall be
paid in accordance with this Section 3.2.1 and Section 3.7:

(i)

Continuing  payments  of  Executive’s  then-current  Base  Salary  for  the
Severance Period (as defined in Section 3.5 herein), payable subject to standard federal and
state  payroll  withholding  requirements  in  accordance  with  Employer’s  regular  payroll
practices  on  Employer’s  normal  payroll  schedule  over  the  Severance  Period,  subject  to
Section 3.7;

(ii)

Employer  shall  pay  to  Executive  a  lump  sum  payment  equal  to  the  gross
sum of any bonuses or portion thereof for any preceding year or for the year of termination
which  have  been  or  are  approved  by  Employer,  but  has  not  been  received  by  Executive
prior to the effective date of termination, less applicable deductions and withholdings, paid
in accordance with Section 2.2 but in no event later than two and one-half (2 1/2) months
following  the  end  of  the  fiscal  year  to  which  it  relates.  For  the  avoidance  of  doubt,
Executive  does  not  have  to  be  employed  by  Employer  on  the  date  such  bonuses  are
approved by Employer to receive such bonuses;

(iii)

So long as Executive is eligible, and so long as Executive remains eligible,
for  and  upon  his  timely  election  of  coverage  under  the  Consolidated  Omnibus  Budget
Reconciliation  Act  of  1985,  or,  if  applicable,  state  or  local  insurance  laws  (“COBRA”),
Employer will continue to pay, directly to the healthcare provider when due, Employer’s
portion  of  the  medical,  vision  and  dental  coverage  premiums  (and  Executive  will  be
responsible for Executive’s portion) for a period of twelve (12) months after the effective
date of Executive’s termination (the “COBRA Payment Period”); provided that, if at any
time  Employer  determines,  in  its  sole  discretion,  that  the  payment  of  the  COBRA
premiums  would  result  in  a  violation  of  the  nondiscrimination  rules  of  Section  105(h)
(2) of the Code or any statute or regulation of similar effect (including but not limited
to the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health
Care  and  Education  Reconciliation  Act),  then  in  lieu  of  providing  the  COBRA
premiums for the remainder of the COBRA Payment Period, Employer will instead pay
Executive  on  the  first  day  of  each  month  of  the  remainder  of  the  COBRA  Payment
Period,  a  fully  taxable  cash  payment  equal  to  the  COBRA  premiums  for  that  month,
subject  to  applicable  tax  withholdings,  for  the  remainder  of  the  COBRA  Payment
Period; and

(iv)

In  the  event  such  termination  of  employment  occurs  on  or  within
three  (3)  months  prior  to  or  within  twelve  (12)  months  following  the  effective  date  of  a
Change  of  Control  (as  defined  herein),  Executive  shall  be  entitled  to  the  additional
following  payments  and  benefits  (for  the  avoidance  of  doubt,  Executive  shall  also  be
entitled to the amounts set forth in Section 3.2.1(i)-(iii)):

6

(1)

Continuing  payments  of  Executive’s  then-current  Base
Salary  for  an  additional  six  (6)  months  following  the  end  of  the  Severance
Period,  payable  subject  to  standard  federal  and  state  payroll  withholding
requirements  in  accordance  with  Employer’s  regular  payroll  practices  on
Employer’s normal payroll schedule over the six (6) month period immediately
following the end of the Severance Period, subject to Section 3.7;

(2)

Employer  shall  pay  to  Executive  a  lump  sum  payment
equal  to  1.5  times  the  Annual  Expectancy  Bonus  Amount  (target  bonus),  less
applicable deductions and withholdings, paid within thirty (30) days of the later
of (a) the effective date of the Change of Control or (b) Executive’s termination,
if such termination occurs on or after the effective date of a Change of Control;  

(3)

Continued  payment  of  Employer’s  portion  of  Executive’s
COBRA  premiums  for  an  additional  six  (6)  months  following  the  end  of  the
COBRA  Payment  Period,  subject  to  the  terms,  conditions  and  payment
provisions set forth in Section 3.2.1(iii); and

(4)

In the event such termination of employment occurs (A) on
or within three (3) months prior to the effective date of a Change of Control, all
unvested  stock  options  and  other  equity  awards  held  by  Executive  and
outstanding on the effective date of termination shall become fully vested on the
effective  date  of  the  Change  of  Control,  or  (B)  within  twelve  (12)  months
following the effective date of a Change of Control, provided that any surviving
corporation  or  acquiring  corporation  assumes  Executive’s  stock  options  and/or
other equity awards, as applicable, or substitutes similar stock options or equity
awards  for  Executive’s  stock  options  and/or  equity  awards,  as  applicable,  in
accordance  with  the  terms  of  Employer’s  applicable  equity  incentive  plans,  all
such  unvested  stock  options  and  other  equity  awards  held  by  Executive  and
outstanding on the effective date of termination shall become fully vested on the
date of such termination.

For purposes of this Employment Agreement, “Change of Control” means, in each case
as approved by the Board and the requisite stockholders of Employer, (i) any consolidation or
merger of Employer with or into any other corporation or other entity or person, or any other
corporate  reorganization,  in  which  the  stockholders  of  Employer  immediately  prior  to  such
consolidation, merger or reorganization, own, in the aggregate, less than 50% of the surviving
entity’s  voting  power  and/or  outstanding  capital  stock  immediately  after  such  consolidation,
merger  or  reorganization,  or  any  transaction  or  series  of  related  transactions  (including  any
transaction  which  results  from  an  option  agreement  or  binding  letter  of  intent  with  a  third
party)  to  which  Employer  or  any  of  its  stockholders  is  a  party  in  which  in  excess  of  50%  of
Employer’s voting power and/or outstanding capital stock is transferred, or pursuant to which
any person or group of affiliated persons obtains in excess of 50% of Employer’s voting power
and/or outstanding capital stock, excluding any consolidation or merger effected exclusively to
change  the  domicile  of  Employer;  or  (ii)  any  sale,  license  or  other  disposition  (including
through  a  Board  and  stockholder  approved  division  or  spin-off  transaction)  of  all  or
substantially all of the assets of Employer and/or any of its subsidiaries or any sale, exclusive

7

license  or  other  disposition  of  all  or  substantially  all  of  Employer’s  intellectual  property,  as
reasonably  determined  based  upon  the  potential  earning  power  of  the  assets  or  intellectual
property; provided, however, that none of the following shall constitute a Change of Control:
(A)  transfers  of  capital  stock  by  an  existing  stockholder  as  a  result  of  death  or  otherwise  for
estate  planning  purposes  or  to  such  stockholder’s  affiliates  or  to  any  of  Employer’s  other
existing  stockholders,  and  (B)  issuances  of  equity  securities  of  Employer  in  connection  with
financings for working capital and other general corporate purposes; and, provided further, that
such “Change of Control” qualifies as either a change in ownership of Employer as defined in
Section  409A  of  the  Code  (“Section  409A”)  or  a  change  in  the  ownership  of  a  substantial
portion of Employer’s assets as defined in Section 409A, as the case may be.

3.2.2 Termination by Executive Other than For Good Reason; Termination
Upon  Non-Renewal  by  Executive;  Termination  by  Employer  for  Cause.  In  the  event
Executive’s  employment  is  terminated  by  Executive  other  than  for  Good  Reason  pursuant  to
Section  3.1.5  hereof  (“By  Executive”)  or  by  Executive  pursuant  to  Section  3.1.6  hereof
(“Termination  Upon  Non-Renewal”)  or  by  Employer  pursuant  to  Section  3.1.3  hereof
(“Termination  by  Employer  for  Cause”),  Executive  shall  be  entitled  to  no  further
compensation or other benefits under this Employment Agreement except as to that portion of
any unpaid salary and other benefits accrued and earned by him hereunder up to and including
the  effective  date  of  such  termination  and  to  offer  COBRA  coverage  at  Executive’s  cost
pursuant to applicable law.

3.2.3  Termination  Upon  Non-Renewal  by  Employer.  In  the  event  Executive’s
employment  is  terminated  by  Employer  pursuant  to  Section  3.1.6  hereof,  then  during  the  ninety
(90)-day notice period of Section 2.4, Employer shall continue to pay to Executive his then-current
Base Salary and benefits subject to standard federal and state payroll withholding requirements and
in  accordance  with  Employer’s  regular  payroll  practices,  and  no  later  than  the  effective  date  of
termination of employment, Employer shall pay to Executive any such unpaid salary accrued and
earned  by  him  up  to  and  including  the  effective  date  of  termination.  In  addition,  in  the  event
Executive’s  employment  is  terminated  by  Employer  pursuant  to  Section  3.1.6  hereof,  then
provided  Executive  executes  and  does  not  revoke  a  Release  in  accordance  with  Section  3.7,
Executive  shall  be  entitled  to  the  following,  which  payments  and  benefits  shall  be  paid  in
accordance with this Section 3.2.3 and Section 3.7:

(i)

Continuing  payments  of  Executive’s  then-current  Base  Salary  for  the
Severance  Period  payable  subject  to  standard  federal  and  state  payroll  withholding
requirements  in  accordance  with  Employer’s  regular  payroll  practices  on  Employer’s
normal payroll schedule over the Severance Period, subject to Section 3.7;

(ii)

Employer shall pay to Executive a lump sum payment equal to the gross sum
of  any  bonuses  or  portion  thereof  for  any  preceding  year  or  for  the  year  of  termination
which  have  been  or  are  approved  by  Employer,  but  has  not  been  received  by  Executive
prior to the effective date of termination, less applicable deductions and withholdings,
paid in accordance with Section 2.2 but in no event later than two and one-half (2 1/2)
months  following  the  end  of  the  fiscal  year  to  which  it  relates.  For  the  avoidance  of
doubt, Executive does not have to be employed by Employer on the date such bonuses
are approved by Employer to receive such bonuses; and

8

(iii)

So long as Executive is eligible, and so long as Executive remains eligible,
for  and  upon  his  timely  election  of  coverage  under  COBRA,  Employer  will  continue  to
pay,  directly  to  the  healthcare  provider  when  due,  Employer’s  portion  of  the  medical,
vision  and  dental  coverage  premiums  (and  Executive  will  be  responsible  for  Executive’s
portion)  for  the  COBRA  Payment  Period;  provided  that,  if  at  any  time  Employer
determines,  in  its  sole  discretion,  that  the  payment  of  the  COBRA  premiums  would
result in a violation of the nondiscrimination rules of Section 105(h)(2) of the Code or
any statute or regulation of similar effect (including but not limited to the 2010 Patient
Protection  and  Affordable  Care  Act,  as  amended  by  the  2010  Health  Care  and
Education Reconciliation Act), then in lieu of providing the COBRA premiums for the
remainder of the COBRA Payment Period, Employer will instead pay Executive on the
first day of each month of the remainder of the COBRA Payment Period, a fully taxable
cash payment equal to the COBRA premiums for that month, subject to applicable tax
withholdings, for the remainder of the COBRA Payment Period.

3.3

Nature of Payments. All amounts to be paid by Employer to Executive pursuant
to  Sections  3.2.1(i)  —  (iv)  and  3.2.3(i)  —  (iii)  are  considered  by  the  parties  to  be  severance
payments  and  are  in  lieu  of,  and  not  in  addition  to,  any  benefits  to  which  Executive  may
otherwise be entitled under any Employer severance plan, policy or program.

3.4

Duties Upon Termination. During the Severance Period, if there is a Severance

Period applicable to Executive’s termination of employment from Employer, Executive shall
fully  cooperate  with  Employer  in  all  matters  relating  to  the  winding  up  of  Executive’s
pending work including, but not limited to, any litigation in which Employer is involved, and
the orderly transfer of any such pending work to such other employees as may be designated
by  Employer.  Notwithstanding  the  foregoing,  such  cooperation  requirement  shall  not
unreasonably  interfere  with  his  then  current  employment  or  business  activities.  With
Employer’s  prior  approval,  Executive  shall  be  reimbursed  for  all  expenses  reasonably
incurred  in  connection  with  such  cooperation.  Following  the  end  of  the  Severance  Period,
Executive  will  be  released  from  any  duties  and  obligations  hereunder  (except  those  duties
and  obligations  set  forth  in  Article  4  hereof).  In  the  event  of  termination  of  Executive’s
employment pursuant to Sections 3.1.1 through 3.1.7 hereof, the obligations of Employer to
Executive  will  be  as  set  forth  in  Section  3.2  hereof.  Upon  termination,  Executive  shall
immediately  resign  from  any  position  on  the  Board  (including  his  position  as  a  director  on
the Board), and from his position as CEO and President of Employer.

3.5

Severance Period. “Severance Period” shall mean a period of twelve (12) months

beginning on the effective date of Executive’s termination of employment with Employer.

3.6

Release.  Notwithstanding  any  provision  of  this  Employment  Agreement  to  the
contrary, in no event shall the timing of Executive’s execution of the Release, directly or indirectly,
result in Executive designating the calendar year of payment, and if a payment that is subject to the
requirements  of  Section  409A  of  the  Code  and  is  subject  to  execution  of  the  Release  could  be
made in more than one taxable year based on when the Release is executed or becomes effective,
payment shall be made in the later year.

3.7

Commencement  of  Severance  Payments.  The  severance  payments  and  benefits
set  forth  in  Sections  3.2.1(i)  —  (iv)  (Termination  by  Employer  for  Death,  Disability,  Without
Cause,  by  Executive  for  Good  Reason)  and  Sections  3.2.3(i)  —  (iii)  (Termination  Upon  Non-
Renewal by Employer) above will not be paid or provided unless Executive executes and does not
revoke the Release and the Release is enforceable and effective as provided in the Release on or
before the date that is the sixtieth (60th) day following the effective date of termination (such 60th
day,  the  “Severance  Pay  Commencement  Date”).  No  cash  severance  payments  will  be  paid
pursuant  to  Sections  3.2.1  or  3.2.3  prior  to  the  Severance  Pay  Commencement  Date.  On  the
Severance Pay Commencement Date, Employer will pay in a lump sum the aggregate amount of
the cash severance payments that Employer would have paid Executive through such date had the
payments  commenced  on  the  effective  date  of  termination  through  the  Severance  Pay
Commencement  Date,  with  the  balance  paid  thereafter  on  the  applicable  schedules  described
above.  Notwithstanding  any  other  provision  of  this  Employment  Agreement  to  the  contrary,  it  is
intended  that  the  payment  of  severance  upon  termination  for  Good  Reason  by  Executive  in
accordance  with  Section  3.1.7  satisfy  the  safe  harbor  set  forth  in  Treasury  Regulation  Section
1.409A-1(n)(2)(ii)),  and  any  severance  payment  made  pursuant  to  this  Employment  Agreement
shall  satisfy  the  exemptions  from  the  application  of  Section  409A  of  the  Code  provided  under
Treasury Regulation Sections 1.409A-1(b)(4), and 1.409A-1 (b)(9).

SECTION 4. CONFIDENTIALITY, INVENTION RIGHTS, NON-COMPETITION
AND NON-SOLICITATION

4.1

Confidentiality, Invention Rights, Non-Competition and Non-Solicitation. The
parties  hereto  have  entered  into  a  Confidentiality,  Invention  Rights,  Non-Competition  and  Non-
Solicitation Agreement, which may be amended by the parties from time to time without regard to
this Employment Agreement. The Confidentiality, Invention Rights, Non-Competition and Non-
Solicitation  Agreement  contains  provisions  that  are  intended  by  the  parties  to  survive  and  do
survive termination of this Employment Agreement.

4.2

Remedies.  Executive  acknowledges  and  agrees  that  (a)  Employer  will  be
irreparably  injured  in  the  event  of  a  breach  by  Executive  of  any  of  his  obligations  under  this
Article 4; (b) monetary damages will not be an adequate remedy for any such breach; and (c) in the
event of any such breach, the Employer will be entitled to injunctive relief, in addition to any other
remedy which it may have, and Executive shall not oppose such injunctive relief based upon the
extent of the harm or the adequacy of monetary damages.

SECTION 5. MISCELLANEOUS PROVISIONS

5.1

Severability. If in any jurisdiction any term or provision hereof is determined to be
invalid  or  unenforceable,  (a)  the  remaining  terms  and  provisions  hereof  shall  be  unimpaired,  (b)
any  such  invalidity  or  unenforceability  in  any  jurisdiction  shall  not  invalidate  or  render
unenforceable such provision in any other jurisdiction, and (c) the invalid or unenforceable term or
provision shall, for purposes of such jurisdiction, be deemed replaced by a term or provision that is
valid  and  enforceable  and  that  comes  closest  to  expressing  the  intention  of  the  invalid  or
unenforceable term or provision.

agreements and understandings of the parties hereto, oral or written, with respect to the subject
matter hereof, including but not limited to the Prior Agreement. No representation, promise or
inducement  has  been  made  by  either  party  that  is  not  embodied  in  this  Employment
Agreement,  and  neither  party  shall  be  bound  by  or  liable  for  any  alleged  representation,

5.7

Headings. The headings contained herein are for the sole purpose of convenience
of reference, and shall not in any way limit or affect the meaning or interpretation of any of the
terms or provisions of this Employment Agreement.

5.8

Binding Effect; Successors and Assigns. Executive may not delegate his duties or
assign  his  rights  hereunder.  This  Employment  Agreement  will  inure  to  the  benefit  of,  and  be
binding  upon,  the  parties  hereto  and  their  respective  heirs,  legal  representatives,  and  successors.
Employer may assign this Employment Agreement to any entity purchasing all or substantially all
of the assets of Employer.

5.9 Waiver, etc. The failure of either of the parties hereto to at any time enforce any of
the provisions of this Employment Agreement shall not be deemed or construed to be a waiver of

provision  hereof  or  the  right  of  either  of  the  parties  hereto  to  thereafter  enforce  each  and  every
provision of this Employment Agreement. No waiver of any breach of any of the provisions of this
Employment Agreement shall be effective unless set forth in a written instrument executed by the
party  against  whom  or  which  enforcement  of  such  waiver  is  sought,  and  no  waiver  of  any  such
breach shall be construed or deemed to be a waiver of any other or subsequent breach.

5.10 Continuing Effect. Provisions of this Employment Agreement which by their
terms must survive the termination of this Employment Agreement in order to effectuate the
intent  of  the  parties  will  survive  any  such  termination,  whether  by  expiration  of  the  term,
termination of Executive’s employment, or otherwise, for such period as may be appropriate
under the circumstances.

5.11 Representations  and  Warranties  of  Executive.  Executive  hereby  represents  and
warrants  to  Employer  that  to  the  knowledge  of  Executive,  Executive  is  not  bound  by  any  non-
competition or other agreement which would prevent his performance hereunder.

5.12

Section 409A of the Code. This Employment Agreement is intended to comply
with  Section  409A  of  the  Code  and  its  corresponding  regulations,  or  an  exemption,  and
payments may only be made under this Employment Agreement upon an event and in a manner
permitted  by  Section  409A  of  the  Code,  to  the  extent  applicable.  Payment  under  this
Employment  Agreement  is  intended  to  be  exempt  from  Code  Section  409A  under  the  “short-
term  deferral”  exception  set  forth  in  Treasury  Regulation  Section  1.409A-1(b)(4),  to  the
maximum  extent  applicable,  and  then  under  the  “separation  pay”  exception  set  forth  in
Treasury Regulation Section 1.409A-1(b)(9), to the maximum extent applicable. All payments
to  be  made  upon  a  termination  of  employment  under  this  Employment  Agreement  may  only
be made upon a “separation from service” within the meaning of Treasury Regulation Section
1.409A-1(h)  (or  any  successor  provision)  (a  “Separation  from  Service”).  For  purposes  of
Code  Section  409A,  the  right  to  a  series  of  installment  payments  under  this  Employment
Agreement  shall  be  treated  as  a  right  to  a  series  of  separate  payments.  In  no  event  may  the
Executive, directly or indirectly, designate the calendar year of a payment. If the termination
of employment giving rise to the payments described in Section 3.2.1 is not a Separation from
Service, then the amounts otherwise payable pursuant to Section 3.2.1 will instead be deferred
without interest and paid when Executive experiences a Separation from Service.

12

Notwithstanding  anything  in  this  Employment  Agreement  to  the  contrary  or  otherwise,  with
respect  to  any  expense,  reimbursement  or  in-kind  benefit  provided  pursuant  to  this
Employment  Agreement  that  constitutes  a  “deferral  of  compensation”  within  the  meaning  of
Section  409A  of  the  Code  and  its  implementing  regulations  and  guidance,  (a)  the  expenses
eligible for reimbursement or in-kind benefits provided to Executive must be incurred during
the  Amended  Employment  Term  (or  applicable  survival  period),  (b)  the  amount  of  expenses
eligible for reimbursement or in-kind benefits provided to Executive during any calendar year
will not affect the amount of expenses eligible for reimbursement or in-kind benefits provided
to  Executive  in  any  other  calendar  year,  (c)  the  reimbursements  for  expenses  for  which
Executive is entitled to be reimbursed shall be made on or before the last day of the calendar
year following the calendar year in which the applicable expense is incurred and (d) the right
to  payment  or  reimbursement  or  in-kind  benefits  hereunder  may  not  be  liquidated  or
exchanged  for  any  other  benefit.  Notwithstanding  any  provision  to  the  contrary  in  this
Employment  Agreement,  if  Executive  is  deemed  by  Employer  at  the  time  of  his  Separation
from  Service  to  be  a  “specified  employee”  for  purposes  of  Section  409A(a)(2)(B)(i)  of  the
Code,  and  if  any  of  the  payments  due  upon  Separation  from  Service  set  forth  herein  and/or
under any other agreement with Employer are deemed to be “deferred compensation,” then to
the  extent  delayed  commencement  of  any  portion  of  such  payments  is  required  to  avoid  a
prohibited  distribution  under  Section  409A(a)(2)(B)(i)  of  the  Code  and  the  related  adverse
taxation  under  Section  409A  of  the  Code,  such  payments  will  not  be  provided  to  Executive
prior to the earliest of (i) the expiration of the six (6)-month period measured from the date of
Executive’s Separation from Service with Employer, (ii) the date of Executive’s death or (iii)
such  earlier  date  as  permitted  under  Section  409A  of  the  Code  without  the  imposition  of
adverse taxation. Upon the first business day following the expiration of such applicable Code
Section  409A(a)(2)(B)(i)  period,  all  payments  deferred  pursuant  to  this  Section  5.12  will  be
paid in a lump sum to Executive, and any remaining payments due will be paid as otherwise
provided  in  this  Employment  Agreement  or  in  the  applicable  agreement.  No  interest  will  be
due on any amounts so deferred.

5.13

Section  280G.  Notwithstanding  any  other  provision  of 

this  Employment
Agreement or any other plan, arrangement or agreement to the contrary, if any of the payments or
benefits provided or  to  be  provided  by Employer  or  its  affiliates  to  Executive or for Executive’s
benefit  pursuant  to  the  terms  of  this  Employment  Agreement  or  otherwise  (the  “Covered
Payments”)  constitute  parachute  payments  (the  “Parachute  Payments”)  within  the  meaning  of
Section  280G  of  the  Code  and,  but  for  this  Section  5.13,  would  be  subject  to  the  excise  tax
imposed  under  Section  4999  of  the  Code  (or  any  successor  provision  thereto)  or  any  similar  tax
imposed by state or local law or any interest or penalties with respect to such taxes (collectively,
the  “Excise  Tax”),  then  prior  to  making  the  Covered  Payments,  a  calculation  shall  be  made
comparing  (i)  the  Net  Benefit  (as  defined  below)  to  Executive  of  the  Covered  Payments  after
payment of the Excise Tax to (ii) the Net Benefit to Executive if the Covered Payments are limited
to  the  extent  necessary  to  avoid  being  subject  to  the  Excise  Tax.  Only  if  the  amount  calculated
under clause (i) above is less than the amount under clause (ii) above will the Covered Payments
be reduced to the minimum extent necessary to ensure that no portion of the Covered Payments is
subject to the Excise Tax. “Net Benefit” shall mean the present value of the Covered Payments net
of all federal, state, local, foreign income, employment and excise taxes.

13

(a)
following:

Any  such  reduction  shall  be  made  in  accordance  with  Section  409A  and  the

(i)

(ii)

(iii)

(iv)

the  Covered  Payments  consisting  of  cash  severance  benefits  that  do  not
constitute nonqualified deferred compensation subject to Section 409A shall
be reduced first, in reverse chronological order; and

all  other  Covered  Payments  consisting  of  cash  payments,  and  Covered
Payments consisting of accelerated vesting of equity based awards to which
Treas. Reg. §1.280G-1 Q/A-24(c) does not apply, and that in either case do
not constitute nonqualified deferred compensation subject to Section 409A,
shall be reduced second, in reverse chronological order; and

all  Covered  Payments  consisting  of  cash  payments 
that  constitute
nonqualified  deferred  compensation  subject  to  Section  409A  shall  be
reduced third, in reverse chronological order; and

all  Covered  Payments  consisting  of  accelerated  vesting  of  equity-based
awards to which Treas. Reg. § 1.280G-1 Q/A-24(c) applies shall be the last
Covered Payments to be reduced.

(b)

Any determination required under this Section 5.13 shall be made in writing in good
faith  by  an  independent  accounting  firm  selected  by  Employer  and  reasonably  acceptable  to  the
Executive (the “Accountants”). Employer and Executive shall provide the Accountants with such
information  and  documents  as  the  Accountants  may  reasonably  request  in  order  to  make  a
determination under this Section 5.13. For purposes of making the calculations and determinations
required by this Section 5.13, the Accountants may rely on reasonable, good-faith assumptions and
approximations  concerning  the  application  of  Section  280G  and  Section  4999  of  the  Code.  The
Accountants’  determinations  shall  be  final  and  binding  on  Employer  and  Executive.  Employer
shall be responsible for all fees and expenses incurred by the Accountants in connection with the
calculations required by this Section 5.13.

(c)

It  is  possible  that  after  the  determinations  and  selections  made  pursuant  to  this
Section  5.13.  Executive  will  receive  Covered  Payments  that  are  in  the  aggregate  more  than  the
amount intended or required to be provided after application of this Section 5.13 (“Overpayment”)
or less than the amount intended or required to be provided after application of this Section 5.13
(“Underpayment”).

(i)

In the event that: (A) the Accountants determine, based upon the assertion of
a  deficiency  by  the  Internal  Revenue  Service  against  either  Employer  or
Executive  that  the  Accountants  believe  has  a  high  probability  of  success,
that  an  Overpayment  has  been  made  or  (B)  it  is  established  pursuant  to  a
final  determination  of  a  court  or  an  Internal  Revenue  Service  proceeding
that  has  been  finally  and  conclusively  resolved  that  an  Overpayment  has
been  made,  then  Executive  shall  pay  any  such  Overpayment  to  Employer
together with interest at the applicable federal rate (as defined in Section

14

(ii)

7872(f)(2)(A)  of  the  Code)  from  the  date  of  Executive’s  receipt  of  the
Overpayment until the date of repayment.

In the event that: (A) the Accountants, based upon controlling precedent or
substantial authority, determine that an Underpayment has occurred or (B) a
court  of  competent  jurisdiction  determines  that  an  Underpayment  has
occurred, any such Underpayment will be paid promptly by Employer to or
for  the  benefit  of  Executive  together  with  interest  at  the  applicable  federal
rate  (as  defined  in  Section  7872(f)(2)(A)  of  the  Code)  from  the  date  the
amount  should  have  otherwise  been  paid  to  Executive  until  the  payment
date.

5.14 Dispute  Resolution.  The  parties  recognize  that  litigation  in  federal  or  state
courts  or  before  federal  or  state  administrative  agencies  of  disputes  arising  out  of  the
Executive’s  employment  with  the  Employer  or  out  of  this  Employment  Agreement,  or  the
Executive’s  termination  of  employment  or  termination  of  this  Employment  Agreement,  may
not be in the best interests of either the Executive or Employer, and may result in unnecessary
costs,  delays,  complexities,  and  uncertainty.  The  parties  agree  that  any  dispute  between  the
parties  arising  out  of  or  relating  to  the  negotiation,  execution,  performance  or  termination  of
this Employment Agreement or the Executive’s employment, including, but not limited to, any
claim  arising  out  of  this  Employment  Agreement,  claims  under  Title  VII  of  the  Civil  Rights
Act  of  1964,  as  amended,  the  Civil  Rights  Act  of  1991,  the  Age  Discrimination  in
Employment Act of 1967, the Americans with Disabilities Act of 1990, Section 1981 of the
Civil  Rights  Act  of  1966,  as  amended,  the  Family  Medical  Leave  Act,  the  Executive
Retirement  Income  Security  Act,  and  any  similar  federal,  state  or  local  law,  statute,
regulation,  or  any  common  law  doctrine,  whether  that  dispute  arises  during  or  after
employment, shall be settled by binding arbitration in accordance with the National Rules for
the  Resolution  of  Employment  Disputes  of  the  American  Arbitration  Association;  provided
however,  that  this  dispute  resolution  provision  shall  not  apply  to  any  separate  agreements
between  the  parties  that  do  not  themselves  specify  arbitration  as  an  exclusive  remedy.  The
location  for  the  arbitration  shall  be  the  Philadelphia,  Pennsylvania  metropolitan  area.  Any
award  made  by  such  panel  shall  be  final,  binding  and  conclusive  on  the  parties  for  all
purposes,  and  judgment  upon  the  award  rendered  by  the  arbitrators  may  be  entered  in  any
court  having  jurisdiction  thereof.  The  arbitrators’  fees  and  expenses  and  all  administrative
fees  and  expenses  associated  with  the  filing  of  the  arbitration  shall  be  borne  by  Employer.
The  parties  acknowledge  and  agree  that  their  obligations  to  arbitrate  under  this  Section
survive the termination of this Employment Agreement and continue after the termination of
the  employment  relationship  between  Executive  and  Employer.  The  parties  each  further
agree that the arbitration provisions of this Employment Agreement shall provide each party
with its exclusive remedy, and  each  party  expressly  waives  any  right  it  might  have  to  seek
redress  in  any  other  forum,  except  as  otherwise  expressly  provided  in  this  Employment
Agreement. By election arbitration as the means for final settlement of all claims, the parties
hereby waive their respective rights to, and agree not to, sue each other in any action in
a  Federal,  State  or  local  court  with  respect  to  such  claims,  but  may  seek  to  enforce  in
court  an  arbitration  award  rendered  pursuant  to  this  Employment  Agreement.  The
parties specifically agree to waive their respective rights to a trial by jury, and further
agree that no demand, request or motion will be made for trial by jury.

EMPLOYMENT AGREEMENT

This  EMPLOYMENT  AGREEMENT  (the  “Employment  Agreement”),  effective  as  of
January 1, 2023 (“Agreement Effective Date”), is made by and between Aclaris Therapeutics, Inc.,
a corporation organized under the laws of the State of Delaware (“Employer”) and Kevin Balthaser
(“Executive”).

WHEREAS,  Executive  desires  to  provide  services  to  Employer  and  Employer  desires  to

retain the services of Executive;

WHEREAS,  Employer  and  Executive  desire  to  formalize  the  terms  and  conditions  of

Executive’s employment with Employer; and

WHEREAS,  this  Employment  Agreement  has  been  duly  approved  and  its  execution  has
been duly authorized by the Compensation Committee of the Employer’s Board of Directors (the
“Board”).

NOW, THEREFORE, Employer and Executive hereby agree as follows:

SECTION 1. EMPLOYMENT

1.1

General.  Employer  hereby  agrees  to  employ  Executive  in  the  capacity  of  Chief
Financial Officer (“CFO”). Executive hereby accepts such employment upon the terms and subject
to the conditions herein contained.

1.2

Authority  and  Duties.  Executive  shall  have  full  responsibility  as  the  CFO  of
Employer and all authority normally accorded to such position. Executive agrees to perform such
duties  and  responsibilities  commensurate  with  the  position  of  CFO  as  may  reasonably  be
determined by the Board.

1.2.1  Reporting.  During  Executive’s  employment  with  Employer,  Executive  will

report directly to, and take direction from, the Chief Executive Officer (the “CEO”).  

that  would 

1.2.2 Time to Be Devoted to Employment. During Executive’s Employment with
Employer, Executive shall diligently devote his efforts, business time, attention and energies to the
business of Employer and will not, while employed by Employer, undertake or engage in any other
interfere  with  Executive’s
employment,  occupation  or  business  enterprise 
responsibilities and the performance of Executive’s duties hereunder except for (i) reasonable time
devoted  to  volunteer  services  for  or  on  behalf  of  such  religious,  educational,  non-profit  and/or
other  charitable  organization  as  Executive  may  wish  to  serve,  (ii)  reasonable  time  devoted  to
activities in the non-profit and business communities consistent with Executive’s duties; and (iii)
reasonable time devoted to service as a member of the board of directors of the entities listed on
Exhibit A  or  as  otherwise  permitted  pursuant  to  Section  1.3.  This  restriction  shall  not,  however,
preclude Executive (x) from owning less than one percent (1%) of the total outstanding shares of a
publicly  traded  company,  or  (y)  from  employment  or  service  in  any  capacity  with  Affiliates  of
Employer.  As used in this Employment Agreement, “Affiliates” means an entity under common
management or control with Employer.

1

1.3

Other  Responsibilities.  Notwithstanding  Section  1.2.2  above,  Executive  will  not
engage in any other for-profit business, profession or occupation, including as a member of a board
of  directors  of  any  third  party,  for  compensation  which  would  materially  conflict  or  materially
interfere with the rendition of services hereunder, without the prior written consent of the Board,
which  shall  not  be  unreasonably  withheld.   Any  uncertainty  as  to  whether  such  a  conflict  exists
will  be  raised  by  Executive  for  determination  by  the  Board,  acting  reasonably.  The  Board
acknowledges that Executive has ongoing participation in other private and public businesses that
have been disclosed by Executive and are listed on Exhibit A and that such participation does not,
in  any  way,  conflict  with  his  role  at  Employer.    Except  for  the  businesses  listed  on  Exhibit  A,
which  have  already  been  approved,  Executive  agrees  to  disclose  to  the  Board  and  receive  prior
written consent from the Board to participate as a director, with any competing company whether it
is  a  private  or  public  company.  Executive  further  agrees  to  disclose  any  other  director  positions
with  any  other  company  that  may  materially  affect  his  ability  to  perform  his  duties  and
responsibilities  under  this  Employment  Agreement.    Notwithstanding  the  above,  nothing  herein
shall limit or preclude Executive from managing any passive investments made by Executive.

1.4

Location  of  Employment.  Executive’s  principal  place  of  employment  during  his
employment with Employer shall be in Wayne, Pennsylvania or such other location as Employer
and Executive shall agree.

SECTION 2.  COMPENSATION AND BENEFITS

2.1

Salary. Employer will pay to Executive an annual base salary of $444,000 payable
subject  to  standard  federal  and  state  payroll  withholding  requirements  in  accordance  with  the
regular payroll practices of Employer (“Base Salary”). The annual Base Salary may be increased
(but  not  decreased)  during  the  term  of  this  Employment  Agreement  by  the  Board  in  its  sole
discretion.

2.2

Additional  Compensation.  In  addition  to  the  salary  set  forth  in  Section  2.1,
Executive shall be entitled to receive a cash bonus in accordance with the terms of this Section 2.2.
For each fiscal year of Employer, beginning January 1, during the Employment Term (as defined in
Section 2.4 hereof), Executive shall be eligible to receive a cash bonus based on (i) the “Annual
Bonus Expectancy Amount,” which shall be an amount equal to 40% of Executive’s Base Salary
for  the  applicable  fiscal  year,  and  (ii)  Executive’s  attainment  of  performance  targets  and  other
reasonable criteria established by the Board, to the extent possible, by the end of the first month of
such fiscal year. Depending on the targets and criteria which are achieved or met, the amount of the
cash bonus actually payable to Executive for each fiscal year will be an amount from zero to and
including the Annual Bonus Expectancy Amount. Any cash bonus amount payable pursuant to this
Section  2.2  shall  be  paid  to  Executive  as  soon  as  practicable,  but  in  no  event  later  than  two  and
one-half (2 1/2) months, following the end of the fiscal year to which it relates. For the avoidance
of doubt, Executive does not have to be employed by Employer on the date such bonus is approved
or paid by Employer to receive such bonus.

2.3

Executive Benefits. In addition to the salary and additional compensation set forth
in  Sections  2.1  and  2.2,  Executive  shall  also  be  entitled  to  the  following  benefits  during
Executive’s employment hereunder:

2

2.3.1  Expenses.  Employer  will  promptly  reimburse  Executive  for  expenses  he
reasonably incurs in connection with the performance of his duties (including business travel and
entertainment expenses), in accordance with Employer’s standard expense reimbursement policy,
as the same may be modified by Employer from time to time; provided, however, that Executive
has provided Employer with documentation of such expenses in accordance with the Employer’s
expense  reimbursement  policies  and  applicable  tax  requirements.  For  the  avoidance  of  doubt,  to
the extent that any reimbursements payable to Executive are subject to the provisions of Section
409A  of  the  Internal  Revenue  Code  of  1986,  as  amended  (the  “Code”):  (a)  any  such
reimbursements will be paid no later than December 31 of the year following the year in which the
expense  was  incurred,  (b)  the  amount  of  expenses  reimbursed  in  one  year  will  not  affect  the
amount  eligible  for  reimbursement  in  any  subsequent  year,  and  (c)  the  right  to  reimbursement
under  this  Employment  Agreement  will  not  be  subject  to  liquidation  or  exchange  for  another
benefit.

2.3.2  Employer  Plans.    Executive  will  be  eligible  to  participate  on  the  same
basis  as  similarly  situated  employees  in  Employer’s  employee  benefit  plans  and  programs,  as
they  may  be  interpreted,  adopted,  revised  or  deleted  from  time  to  time  in  Employer’s  sole
discretion,  subject  to  and  on  a  basis  consistent  with  the  terms,  conditions  and  overall
administration  of  such  plans  and  programs.  All  matters  of  eligibility  for  coverage  or  benefits
under  any  benefit  plan  shall  be  determined  in  accordance  with  the  provisions  of  such  plan.
Employer retains the unilateral right to amend, modify or terminate any of its employee benefit
plans and programs at any time.

2.3.3 Vacation. Executive shall be eligible for paid vacation leave (not including
regular  holidays)  consistent  with  the  needs  of  the  business.  Vacation  must  be  scheduled  at
those times convenient to Employer’s business as reasonably determined by the CEO.

2.3.4  Coverage.  Nothing  in  this  Employment  Agreement  shall  prevent  Executive
from  participating  in  any  other  compensation  plan  or  benefit  plan  made  available  to  him  by
Employer.

2.3.5 Withholding. All compensation shall be subject to withholding of taxes and

deductions of other amounts as may be required by law.

2.4       Employment Term. Unless earlier terminated pursuant to Section 3.1, Executive’s
employment by Employer pursuant to this Employment Agreement shall continue until the second
anniversary  of  the  Agreement  Effective  Date  (the  “Initial  Term”).  Thereafter,  this  Employment
Agreement  shall  be  automatically  renewed  for  successive  one  (1)  year  periods  (any  subsequent
employment period being referred to herein as the “Renewal Term”, and together with the Initial
Term, the “Employment Term”); provided, however, that either party may elect to not renew this
Employment Agreement by written notice to such effect delivered to the other party at least ninety
(90) days prior to expiration of the Initial Term or the Renewal Term.

SECTION 3.  TERMINATION OF EMPLOYMENT

3.1

Events of Termination. Executive’s employment with Employer will terminate

upon the occurrence of any one or more of the following events:

3

3.1.1  Death.  In  the  event  of  Executive’s  death,  Executive’s  employment  will

terminate on the date of death.

3.1.2  Disability.  In  the  event  of  Executive’s  Disability  (as  hereinafter  defined),
Employer  will  have  the  option  to  terminate  Executive’s  employment  by  giving  a  notice  of
termination to Executive. The notice of termination shall specify the date of termination, which
date shall not be earlier than thirty (30) calendar days after the notice of termination is given. For
purposes  of  this  Employment  Agreement,  “Disability”  has  the  meaning  set  forth  in  Employer’s
long term disability plan.  

3.1.3 Termination by Employer for Cause. Employer may, at its option, terminate
Executive’s  employment  for  Cause  (as  hereinafter  defined)  by  unilateral  action  of  the  Board  of
Directors  upon  giving  a  notice  of  termination  to  Executive.  “Cause”  shall  mean  (i)  Executive’s
conviction of, or guilty plea to, a felony (other than traffic violations); (ii) any act(s) or omission(s)
by  Executive  which  constitutes  gross  negligence  or  a  material  breach  of  Executive’s  duty  of
loyalty;  (iii)  any  material  breach  by  Executive  of  Employer’s  personnel  policies;  (iv)  refusal  to
follow or implement a clear and reasonable directive of Employer; (v) breach of fiduciary duty; or
(vi)  a  material  violation  or  breach  by  Executive  of  this  Employment  Agreement  (other  than  an
event described in the foregoing clauses) or any other agreement between the parties.

3.1.4  Without  Cause  By  Employer.  Employer  may,  at  its  option,  terminate
Executive’s  employment  for  any  reason  whatsoever  (other  than  for  the  other  reasons  set  forth
above  in  this  Section  3.1  that  would  constitute  “Cause”  to  terminate)  by  giving  a  notice  of
termination to Executive, and Executive’s employment shall terminate on the later of the date the
notice of termination is given or the date set forth in such notice of termination.

3.1.5 By Executive. Executive may, at any time, terminate Executive’s employment
for any reason whatsoever by giving a notice of termination to Employer. Executive’s employment
shall terminate on the earlier of (i) thirty (30) calendar days after the date of receipt by Employer
of the notice of termination or (ii) such earlier date as the Employer and Executive shall agree.

this
3.1.6  Termination  Upon  Non-Renewal.  Either  party  may 
Employment  Agreement  and  Executive’s  employment  hereunder  by  providing  the  other  party
notice  in  accordance  with  Section  2.4  above,  in  which  case  this  Employment  Agreement  and
Executive’s  employment  hereunder  shall  terminate  on  the  last  date  of  the  Initial  Term  or  the
Renewal  Term,  as  the  case  may  be.  For  the  avoidance  of  doubt,  Executive  shall  continue  to  be
employed  by  Employer,  on  the  same  terms  and  conditions  as  set  forth  in  this  Employment
Agreement during the ninety (90)-day notice period provided by either party to the other party in
accordance with Section 2.4 above, unless, Employer, in its sole discretion determines that it does
not want Executive to continue to work for Employer, in any capacity, during such notice period.
In such event, Employer shall pay Executive all compensation in accordance with Section 3.2.3.

terminate 

3.1.7  For  Good  Reason  by  Executive.  Executive  may,  at  his  option,  terminate
Executive’s employment for “Good Reason” by giving a notice of termination to Employer in the
event that, in the absence of events that would support a termination of Executive for Cause:

4

(i)

there  is  a  material  failure  of  Employer  (or  successor  employer)  to  pay
Executive’s  salary  or  additional  compensation  or  benefits  hereunder  in  accordance  with  this
Employment Agreement;

(ii)

Executive’s  Base  Salary  is  materially  decreased  without  his  prior  written

consent;

(iii)

Executive  is  assigned  duties  materially  inconsistent  with  his  title  and  the

responsibilities set forth in Executive’s job description, without Executive’s prior written consent;

(iv)

Executive’s place of employment is changed to a location that is greater than
fifty (50) miles from Executive’s current place of employment (disregarding for this purpose any
remote work arrangements); or

(v)

any  other  material  violation  or  breach  by  Employer  of  this  Employment
Agreement.  Notwithstanding  the  foregoing,  none  of  the  events  described  in  clauses  (i)  through
(iv) above shall constitute Good Reason unless Executive shall have notified Employer in writing
describing  the  event  which  constitute  Good  Reason  within  thirty  (30)  days  after  Executive  first
becomes aware of such event and then only if Employer shall have failed to reasonably cure such
events,  if  curable,  within  thirty  (30)  days  after  Employer’s  receipt  of  such  written  notice  and
Executive elects to terminate his employment as a result within thirty (30) days following the end
of such thirty (30) day period (assuming, for the avoidance of doubt, that Employer does not elect
to cure).

3.2

Certain  Obligations  of  Employer  Following  Termination  of  Executive’s
Employment.  Following  the  termination  of  Executive’s  employment  under  the  circumstances
described  below,  Employer  will  pay  to  Executive,  subject  to  standard  federal  and  state  payroll
withholding  requirements  and  in  accordance  with  its  regular  payroll  practices,  the  following
compensation  and  provide  the  following  benefits  (provided  that  the  continuing  payments  of
Executive’s  then-current  Base  Salary,  as  described  below,  shall  occur  no  less  frequently  than
monthly):

3.2.1  Death;  Disability;  Termination  by  Employer  Without  Cause  or  by
Executive  for  Good  Reason.  In  the  event  that  Executive’s  employment  is  terminated  by
Employer  pursuant  to  Section  3.1.1  (“Death”),  Section  3.1.2  (“Disability”),  Section  3.1.4
(“Without  Cause  by  Employer”)  or  by  Executive  pursuant  to  Section  3.1.7  (“Termination  by
Executive for Good Reason”) hereof, and Executive, or his estate, as the case may be, executes
and does not revoke a separation agreement containing a release upon such termination, in a form
provided  by  the  Employer,  of  any  and  all  claims  against  Employer  and  all  related  parties  with
respect  to  all  matters  arising  out  of  Executive’s  employment  by  Employer,  or  the  termination
thereof (the “Release”) in accordance with Section 3.7, Executive, or his estate, as the case may
be, shall be entitled to the following payments and benefits, which payments and benefits shall be
paid in accordance with this Section 3.2.1 and Section 3.7:

(i)

Continuing  payments  of  Executive’s  then-current  Base  Salary  for  the
Severance Period (as defined in Section 3.5 herein), payable subject to standard federal and
state payroll withholding requirements in accordance with Employer’s regular payroll

5

practices  on  Employer’s  normal  payroll  schedule  over  the  Severance  Period,  subject  to
Section 3.7;

(ii)

Employer  shall  pay  to  Executive  a  lump  sum  payment  equal  to  the  gross
sum of any bonuses or portion thereof for any preceding year or for the year of termination
which  have  been  or  are  approved  by  Employer,  but  has  not  been  received  by  Executive
prior to the effective date of termination, less applicable deductions and withholdings, paid
in accordance with Section 2.2 but in no event later than two and one-half (2 1/2) months
following  the  end  of  the  fiscal  year  to  which  it  relates.  For  the  avoidance  of  doubt,
Executive  does  not  have  to  be  employed  by  Employer  on  the  date  such  bonuses  are
approved by Employer to receive such bonuses;

(iii)

So long as Executive is eligible, and so long as Executive remains eligible,
for  and  upon  his  timely  election  of  coverage  under  the  Consolidated  Omnibus  Budget
Reconciliation  Act  of  1985,  or,  if  applicable,  state  or  local  insurance  laws  (“COBRA”),
Employer will continue to pay, directly to the healthcare provider when due, Employer’s
portion  of  the  medical,  vision  and  dental  coverage  premiums  (and  Executive  will  be
responsible for Executive’s portion) for a period of twelve (12) months after the effective
date of Executive’s termination (the “COBRA Payment Period”); provided that, if at any
time  Employer  determines,  in  its  sole  discretion,  that  the  payment  of  the  COBRA
premiums  would  result  in  a  violation  of  the  nondiscrimination  rules  of  Section  105(h)
(2) of the Code or any statute or regulation of similar effect (including but not limited
to the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health
Care  and  Education  Reconciliation  Act),  then  in  lieu  of  providing  the  COBRA
premiums for the remainder of the COBRA Payment Period, Employer will instead pay
Executive  on  the  first  day  of  each  month  of  the  remainder  of  the  COBRA  Payment
Period,  a  fully  taxable  cash  payment  equal  to  the  COBRA  premiums  for  that  month,
subject  to  applicable  tax  withholdings,  for  the  remainder  of  the  COBRA  Payment
Period; and

(iv)

In the event such termination of employment occurs on or within three (3)
months prior to or within twelve (12) months following the effective date of a Change of
Control  (as  defined  herein),  Executive  shall  be  entitled  to  the  additional  following
payments and benefits (for the avoidance of doubt, Executive shall also be entitled to the
amounts set forth in Section 3.2.1(i)-(iii)):

(1)

Employer  shall  pay  to  Executive  a  lump  sum  payment
equal  to  the  Annual  Expectancy  Bonus  Amount  (target  bonus),  less  applicable
deductions and withholdings, paid within thirty (30) days of the later of (a) the
effective  date  of  the  Change  of  Control  or  (b)  Executive’s  termination,  if  such
termination occurs on or after the effective date of a Change of Control; and

(2)

In the event such termination of employment occurs (A) on
or within three (3) months prior to the effective date of a Change of Control, all
unvested  stock  options  and  other  equity  awards  held  by  Executive  and
outstanding on the effective date of termination shall become fully vested on the
effective date of the Change of Control, or (B) within twelve (12) months

6

following the effective date of a Change of Control, provided that any surviving
corporation  or  acquiring  corporation  assumes  Executive’s  stock  options  and/or
other equity awards, as applicable, or substitutes similar stock options or equity
awards  for  Executive’s  stock  options  and/or  equity  awards,  as  applicable,  in
accordance  with  the  terms  of  Employer’s  applicable  equity  incentive  plans,  all
such  unvested  stock  options  and  other  equity  awards  held  by  Executive  and
outstanding on the effective date of termination shall become fully vested on the
date of such termination.

For purposes of this Employment Agreement, “Change of Control” means, in each case
as approved by the Board and the requisite stockholders of Employer, (i) any consolidation or
merger  of  Employer  with  or  into  any  other  corporation  or  other  entity  or  person,  or  any  other
corporate  reorganization,  in  which  the  stockholders  of  Employer  immediately  prior  to  such
consolidation, merger or reorganization, own, in the aggregate, less than 50% of the surviving
entity’s  voting  power  and/or  outstanding  capital  stock  immediately  after  such  consolidation,
merger  or  reorganization,  or  any  transaction  or  series  of  related  transactions  (including  any
transaction which results from an option agreement or binding letter of intent with a third party)
to which Employer or any of its stockholders is a party in which in excess of 50% of Employer’s
voting power and/or outstanding capital stock is transferred, or pursuant to which any person or
group  of  affiliated  persons  obtains  in  excess  of  50%  of  Employer’s  voting  power  and/or
outstanding capital stock, excluding any consolidation or merger effected exclusively to change
the  domicile  of  Employer;  or  (ii)  any  sale,  license  or  other  disposition  (including  through  a
Board  and  stockholder  approved  division  or  spin-off  transaction)  of  all  or  substantially  all  of
the  assets  of  Employer  and/or  any  of  its  subsidiaries  or  any  sale,  exclusive  license  or  other
disposition  of  all  or  substantially  all  of  Employer’s  intellectual  property,  as  reasonably
determined  based  upon  the  potential  earning  power  of  the  assets  or  intellectual  property;
provided, however, that none of the following shall constitute a Change of Control: (A) transfers
of capital stock by an existing stockholder as a result of death or otherwise for estate planning
purposes or to such stockholder’s affiliates or to any of Employer’s other existing stockholders,
and  (B)  issuances  of  equity  securities  of  Employer  in  connection  with  financings  for  working
capital  and  other  general  corporate  purposes;  and,  provided  further,  that  such  “Change  of
Control” qualifies as either a change in ownership of Employer as defined in Section 409A of the
Code  (“Section  409A”)  or  a  change  in  the  ownership  of  a  substantial  portion  of  Employer’s
assets as defined in Section 409A, as the case may be.

3.2.2 Termination by Executive Other than For Good Reason; Termination
Upon  Non-Renewal  by  Executive;  Termination  by  Employer  for  Cause.  In  the  event
Executive’s  employment  is  terminated  by  Executive  other  than  for  Good  Reason  pursuant  to
Section  3.1.5  hereof  (“By  Executive”)  or  by  Executive  pursuant  to  Section  3.1.6  hereof
(“Termination  Upon  Non-Renewal”)  or  by  Employer  pursuant  to  Section  3.1.3  hereof
(“Termination  by  Employer  for  Cause”),  Executive  shall  be  entitled  to  no  further
compensation or other benefits under this Employment Agreement except as to that portion of
any unpaid salary and other benefits accrued and earned by him hereunder up to and including
the  effective  date  of  such  termination  and  to  offer  COBRA  coverage  at  Executive’s  cost
pursuant to applicable law.

7

3.2.3  Termination  Upon  Non-Renewal  by  Employer.  In  the  event  Executive’s
employment  is  terminated  by  Employer  pursuant  to  Section  3.1.6  hereof,  then  during  the  ninety
(90)-day notice period of Section 2.4, Employer shall continue to pay to Executive his then-current
Base Salary and benefits subject to standard federal and state payroll withholding requirements and
in  accordance  with  Employer’s  regular  payroll  practices,  and  no  later  than  the  effective  date  of
termination of employment, Employer shall pay to Executive any such unpaid salary accrued and
earned  by  him  up  to  and  including  the  effective  date  of  termination.  In  addition,  in  the  event
Executive’s  employment  is  terminated  by  Employer  pursuant  to  Section  3.1.6  hereof,  then
provided  Executive  executes  and  does  not  revoke  a  Release  in  accordance  with  Section  3.7,
Executive  shall  be  entitled  to  the  following,  which  payments  and  benefits  shall  be  paid  in
accordance with this Section 3.2.3 and Section 3.7:

(i)

Continuing  payments  of  Executive’s  then-current  Base  Salary  for  the
Severance  Period  payable  subject  to  standard  federal  and  state  payroll  withholding
requirements  in  accordance  with  Employer’s  regular  payroll  practices  on  Employer’s
normal payroll schedule over the Severance Period, subject to Section 3.7;

(ii)

Employer shall pay to Executive a lump sum payment equal to the gross sum
of  any  bonuses  or  portion  thereof  for  any  preceding  year  or  for  the  year  of  termination
which  have  been  or  are  approved  by  Employer,  but  has  not  been  received  by  Executive
prior to the effective date of termination, less applicable deductions and withholdings,
paid in accordance with Section 2.2 but in no event later than two and one-half (2 1/2)
months  following  the  end  of  the  fiscal  year  to  which  it  relates.  For  the  avoidance  of
doubt, Executive does not have to be employed by Employer on the date such bonuses
are approved by Employer to receive such bonuses; and

(iii)

So long as Executive is eligible, and so long as Executive remains eligible,
for  and  upon  his  timely  election  of  coverage  under  COBRA,  Employer  will  continue  to
pay,  directly  to  the  healthcare  provider  when  due,  Employer’s  portion  of  the  medical,
vision  and  dental  coverage  premiums  (and  Executive  will  be  responsible  for  Executive’s
portion)  for  the  COBRA  Payment  Period;  provided  that,  if  at  any  time  Employer
determines,  in  its  sole  discretion,  that  the  payment  of  the  COBRA  premiums  would
result in a violation of the nondiscrimination rules of Section 105(h)(2) of the Code or
any statute or regulation of similar effect (including but not limited to the 2010 Patient
Protection  and  Affordable  Care  Act,  as  amended  by  the  2010  Health  Care  and
Education Reconciliation Act), then in lieu of providing the COBRA premiums for the
remainder of the COBRA Payment Period, Employer will instead pay Executive on the
first day of each month of the remainder of the COBRA Payment Period, a fully taxable
cash payment equal to the COBRA premiums for that month, subject to applicable tax
withholdings, for the remainder of the COBRA Payment Period.

3.3

Nature of Payments. All amounts to be paid by Employer to Executive pursuant
to  Sections  3.2.1(i)  —  (iv)  and  3.2.3(i)  —  (iii)  are  considered  by  the  parties  to  be  severance
payments  and  are  in  lieu  of,  and  not  in  addition  to,  any  benefits  to  which  Executive  may
otherwise be entitled under any Employer severance plan, policy or program.

8

3.4

Duties Upon Termination. During the Severance Period, if there is a Severance

Period applicable to Executive’s termination of employment from Employer, Executive shall
fully  cooperate  with  Employer  in  all  matters  relating  to  the  winding  up  of  Executive’s
pending work including, but not limited to, any litigation in which Employer is involved, and
the orderly transfer of any such pending work to such other employees as may be designated
by  Employer.  Notwithstanding  the  foregoing,  such  cooperation  requirement  shall  not
unreasonably  interfere  with  his  then  current  employment  or  business  activities.  With
Employer’s  prior  approval,  Executive  shall  be  reimbursed  for  all  expenses  reasonably
incurred  in  connection  with  such  cooperation.  Following  the  end  of  the  Severance  Period,
Executive  will  be  released  from  any  duties  and  obligations  hereunder  (except  those  duties
and  obligations  set  forth  in  Article  4  hereof).  In  the  event  of  termination  of  Executive’s
employment pursuant to Sections 3.1.1 through 3.1.7 hereof, the obligations of Employer to
Executive  will  be  as  set  forth  in  Section  3.2  hereof.  Upon  termination,  Executive  shall
immediately resign from his position as CFO of Employer.

3.5

Severance Period. “Severance Period” shall mean a period of twelve (12) months

beginning on the effective date of Executive’s termination of employment with Employer.

3.6

Release.  Notwithstanding  any  provision  of  this  Employment  Agreement  to  the
contrary, in no event shall the timing of Executive’s execution of the Release, directly or indirectly,
result in Executive designating the calendar year of payment, and if a payment that is subject to the
requirements  of  Section  409A  of  the  Code  and  is  subject  to  execution  of  the  Release  could  be
made in more than one taxable year based on when the Release is executed or becomes effective,
payment shall be made in the later year.

3.7

Commencement  of  Severance  Payments.  The  severance  payments  and  benefits
set  forth  in  Sections  3.2.1(i)  —  (iv)  (Termination  by  Employer  for  Death,  Disability,  Without
Cause,  by  Executive  for  Good  Reason)  and  Sections  3.2.3(i)  —  (iii)  (Termination  Upon  Non-
Renewal by Employer) above will not be paid or provided unless Executive executes and does not
revoke the Release and the Release is enforceable and effective as provided in the Release on or
before the date that is the sixtieth (60th) day following the effective date of termination (such 60th
day,  the  “Severance  Pay  Commencement  Date”).  No  cash  severance  payments  will  be  paid
pursuant  to  Sections  3.2.1  or  3.2.3  prior  to  the  Severance  Pay  Commencement  Date.  On  the
Severance Pay Commencement Date, Employer will pay in a lump sum the aggregate amount of
the cash severance payments that Employer would have paid Executive through such date had the
payments  commenced  on  the  effective  date  of  termination  through  the  Severance  Pay
Commencement  Date,  with  the  balance  paid  thereafter  on  the  applicable  schedules  described
above.  Notwithstanding  any  other  provision  of  this  Employment  Agreement  to  the  contrary,  it  is
intended  that  the  payment  of  severance  upon  termination  for  Good  Reason  by  Executive  in
accordance  with  Section  3.1.7  satisfy  the  safe  harbor  set  forth  in  Treasury  Regulation  Section
1.409A-1(n)(2)(ii)),  and  any  severance  payment  made  pursuant  to  this  Employment  Agreement
shall  satisfy  the  exemptions  from  the  application  of  Section  409A  of  the  Code  provided  under
Treasury Regulation Sections 1.409A-1(b)(4), and 1.409A-1 (b)(9).

SECTION 4. CONFIDENTIALITY, INVENTION RIGHTS, NON-COMPETITION
AND NON-SOLICITATION

9

4.1

Confidentiality,  Invention  Rights,  Non-Competition  and  Non-Solicitation. The
parties hereto have entered into an Amended and Restated Confidentiality, Invention Rights, Non-
Competition, and Non-Solicitation Agreement, which may be amended by the parties from time to
time without regard to this Employment Agreement. The Amended and Restated Confidentiality,
Invention Rights, Non-Competition, and Non-Solicitation Agreement contains provisions that are
intended by the parties to survive and do survive termination of this Employment Agreement.

4.2

Remedies.  Executive  acknowledges  and  agrees  that  (a)  Employer  will  be
irreparably  injured  in  the  event  of  a  breach  by  Executive  of  any  of  his  obligations  under  this
Article 4; (b) monetary damages will not be an adequate remedy for any such breach; and (c) in the
event of any such breach, the Employer will be entitled to injunctive relief, in addition to any other
remedy which it may have, and Executive shall not oppose such injunctive relief based upon the
extent of the harm or the adequacy of monetary damages.

5.9 Waiver, etc. The failure of either of the parties hereto to at any time enforce any of

5.10 Continuing Effect. Provisions of this Employment Agreement which by their

intent  of  the  parties  will  survive  any  such  termination,  whether  by  expiration  of  the  term,
termination of Executive’s employment, or otherwise, for such period as may be appropriate
under the circumstances.

5.11 Representations  and  Warranties  of  Executive.  Executive  hereby  represents  and
warrants  to  Employer  that  to  the  knowledge  of  Executive,  Executive  is  not  bound  by  any  non-
competition or other agreement which would prevent his performance hereunder.

5.12

Section 409A of the Code. This Employment Agreement is intended to comply
with  Section  409A  of  the  Code  and  its  corresponding  regulations,  or  an  exemption,  and
payments may only be made under this Employment Agreement upon an event and in a manner
permitted  by  Section  409A  of  the  Code,  to  the  extent  applicable.  Payment  under  this
Employment  Agreement  is  intended  to  be  exempt  from  Code  Section  409A  under  the  “short-
term  deferral”  exception  set  forth  in  Treasury  Regulation  Section  1.409A-1(b)(4),  to  the
maximum  extent  applicable,  and  then  under  the  “separation  pay”  exception  set  forth  in
Treasury Regulation Section 1.409A-1(b)(9), to the maximum extent applicable. All payments
to  be  made  upon  a  termination  of  employment  under  this  Employment  Agreement  may  only
be made upon a “separation from service” within the meaning of Treasury Regulation Section
1.409A-1(h)  (or  any  successor  provision)  (a  “Separation  from  Service”).  For  purposes  of
Code  Section  409A,  the  right  to  a  series  of  installment  payments  under  this  Employment
Agreement  shall  be  treated  as  a  right  to  a  series  of  separate  payments.  In  no  event  may  the
Executive, directly or indirectly, designate the calendar year of a payment. If the termination
of employment giving rise to the payments described in Section 3.2.1 is not a Separation from
Service, then the amounts otherwise payable pursuant to Section 3.2.1 will instead be deferred
without 
interest  and  paid  when  Executive  experiences  a  Separation  from  Service.
Notwithstanding  anything  in  this  Employment  Agreement  to  the  contrary  or  otherwise,  with
respect  to  any  expense,  reimbursement  or  in-kind  benefit  provided  pursuant  to  this
Employment  Agreement  that  constitutes  a  “deferral  of  compensation”  within  the  meaning  of
Section  409A  of  the  Code  and  its  implementing  regulations  and  guidance,  (a)  the  expenses
eligible for reimbursement or in-kind benefits provided to Executive must be incurred during
the Employment Term (or applicable survival period), (b) the amount of expenses eligible for
reimbursement  or  in-kind  benefits  provided  to  Executive  during  any  calendar  year  will  not
affect  the  amount  of  expenses  eligible  for  reimbursement  or  in-kind  benefits  provided  to
Executive  in  any  other  calendar  year,  (c)  the  reimbursements  for  expenses  for  which
Executive is entitled to be reimbursed shall be made on or before the last day of the calendar
year following the calendar year in which the applicable expense is incurred and (d) the right
to  payment  or  reimbursement  or  in-kind  benefits  hereunder  may  not  be  liquidated  or
exchanged  for  any  other  benefit.  Notwithstanding  any  provision  to  the  contrary  in  this
Employment  Agreement,  if  Executive  is  deemed  by  Employer  at  the  time  of  his  Separation
from  Service  to  be  a  “specified  employee”  for  purposes  of  Section  409A(a)(2)(B)(i)  of  the
Code,  and  if  any  of  the  payments  due  upon  Separation  from  Service  set  forth  herein  and/or
under any other agreement with Employer are deemed to be “deferred compensation,” then to
the  extent  delayed  commencement  of  any  portion  of  such  payments  is  required  to  avoid  a
prohibited  distribution  under  Section  409A(a)(2)(B)(i)  of  the  Code  and  the  related  adverse
taxation under Section 409A of the Code, such payments will not be provided to Executive

12

prior to the earliest of (i) the expiration of the six (6)-month period measured from the date of
Executive’s Separation from Service with Employer, (ii) the date of Executive’s death or (iii)
such  earlier  date  as  permitted  under  Section  409A  of  the  Code  without  the  imposition  of
adverse taxation. Upon the first business day following the expiration of such applicable Code
Section  409A(a)(2)(B)(i)  period,  all  payments  deferred  pursuant  to  this  Section  5.12  will  be
paid in a lump sum to Executive, and any remaining payments due will be paid as otherwise
provided  in  this  Employment  Agreement  or  in  the  applicable  agreement.  No  interest  will  be
due on any amounts so deferred.

5.13

Section  280G.  Notwithstanding  any  other  provision  of 

this  Employment
Agreement or any other plan, arrangement or agreement to the contrary, if any of the payments or
benefits provided or  to  be  provided  by Employer  or  its  affiliates  to  Executive or for Executive’s
benefit  pursuant  to  the  terms  of  this  Employment  Agreement  or  otherwise  (the  “Covered
Payments”)  constitute  parachute  payments  (the  “Parachute  Payments”)  within  the  meaning  of
Section  280G  of  the  Code  and,  but  for  this  Section  5.13,  would  be  subject  to  the  excise  tax
imposed  under  Section  4999  of  the  Code  (or  any  successor  provision  thereto)  or  any  similar  tax
imposed by state or local law or any interest or penalties with respect to such taxes (collectively,
the  “Excise  Tax”),  then  prior  to  making  the  Covered  Payments,  a  calculation  shall  be  made
comparing  (i)  the  Net  Benefit  (as  defined  below)  to  Executive  of  the  Covered  Payments  after
payment of the Excise Tax to (ii) the Net Benefit to Executive if the Covered Payments are limited
to  the  extent  necessary  to  avoid  being  subject  to  the  Excise  Tax.  Only  if  the  amount  calculated
under clause (i) above is less than the amount under clause (ii) above will the Covered Payments
be reduced to the minimum extent necessary to ensure that no portion of the Covered Payments is
subject to the Excise Tax. “Net Benefit” shall mean the present value of the Covered Payments net
of all federal, state, local, foreign income, employment and excise taxes.

(a)
following:

Any  such  reduction  shall  be  made  in  accordance  with  Section  409A  and  the

(i)

(ii)

(iii)

(iv)

the  Covered  Payments  consisting  of  cash  severance  benefits  that  do  not
constitute nonqualified deferred compensation subject to Section 409A shall
be reduced first, in reverse chronological order; and

all  other  Covered  Payments  consisting  of  cash  payments,  and  Covered
Payments consisting of accelerated vesting of equity based awards to which
Treas. Reg. §1.280G-1 Q/A-24(c) does not apply, and that in either case do
not constitute nonqualified deferred compensation subject to Section 409A,
shall be reduced second, in reverse chronological order; and

that  constitute
all  Covered  Payments  consisting  of  cash  payments 
nonqualified  deferred  compensation  subject  to  Section  409A  shall  be
reduced third, in reverse chronological order; and

all  Covered  Payments  consisting  of  accelerated  vesting  of  equity-based
awards to which Treas. Reg. § 1.280G-1 Q/A-24(c) applies shall be the last
Covered Payments to be reduced.

13

(b)

Any determination required under this Section 5.13 shall be made in writing in good
faith  by  an  independent  accounting  firm  selected  by  Employer  and  reasonably  acceptable  to  the
Executive (the “Accountants”). Employer and Executive shall provide the Accountants with such
information  and  documents  as  the  Accountants  may  reasonably  request  in  order  to  make  a
determination under this Section 5.13. For purposes of making the calculations and determinations
required by this Section 5.13, the Accountants may rely on reasonable, good-faith assumptions and
approximations  concerning  the  application  of  Section  280G  and  Section  4999  of  the  Code.  The
Accountants’  determinations  shall  be  final  and  binding  on  Employer  and  Executive.  Employer
shall be responsible for all fees and expenses incurred by the Accountants in connection with the
calculations required by this Section 5.13.

(c)

It  is  possible  that  after  the  determinations  and  selections  made  pursuant  to  this
Section  5.13.  Executive  will  receive  Covered  Payments  that  are  in  the  aggregate  more  than  the
amount intended or required to be provided after application of this Section 5.13 (“Overpayment”)
or less than the amount intended or required to be provided after application of this Section 5.13
(“Underpayment”).

(i)

(ii)

In the event that: (A) the Accountants determine, based upon the assertion of
a  deficiency  by  the  Internal  Revenue  Service  against  either  Employer  or
Executive  that  the  Accountants  believe  has  a  high  probability  of  success,
that  an  Overpayment  has  been  made  or  (B)  it  is  established  pursuant  to  a
final  determination  of  a  court  or  an  Internal  Revenue  Service  proceeding
that  has  been  finally  and  conclusively  resolved  that  an  Overpayment  has
been  made,  then  Executive  shall  pay  any  such  Overpayment  to  Employer
together  with  interest  at  the  applicable  federal  rate  (as  defined  in  Section
7872(f)(2)(A)  of  the  Code)  from  the  date  of  Executive’s  receipt  of  the
Overpayment until the date of repayment.

In the event that: (A) the Accountants, based upon controlling precedent or
substantial authority, determine that an Underpayment has occurred or (B) a
court  of  competent  jurisdiction  determines  that  an  Underpayment  has
occurred, any such Underpayment will be paid promptly by Employer to or
for  the  benefit  of  Executive  together  with  interest  at  the  applicable  federal
rate  (as  defined  in  Section  7872(f)(2)(A)  of  the  Code)  from  the  date  the
amount  should  have  otherwise  been  paid  to  Executive  until  the  payment
date.

5.14 Dispute  Resolution.  The  parties  recognize  that  litigation  in  federal  or  state
courts  or  before  federal  or  state  administrative  agencies  of  disputes  arising  out  of  the
Executive’s  employment  with  the  Employer  or  out  of  this  Employment  Agreement,  or  the
Executive’s  termination  of  employment  or  termination  of  this  Employment  Agreement,  may
not be in the best interests of either the Executive or Employer, and may result in unnecessary
costs,  delays,  complexities,  and  uncertainty.  The  parties  agree  that  any  dispute  between  the
parties  arising  out  of  or  relating  to  the  negotiation,  execution,  performance  or  termination  of
this Employment Agreement or the Executive’s employment, including, but not limited to, any
claim  arising  out  of  this  Employment  Agreement,  claims  under  Title  VII  of  the  Civil  Rights
Act of 1964, as amended, the Civil Rights Act of 1991, the Age Discrimination in

14

Employment Act of 1967, the Americans with Disabilities Act of 1990, Section 1981 of the
Civil  Rights  Act  of  1966,  as  amended,  the  Family  Medical  Leave  Act,  the  Executive
Retirement  Income  Security  Act,  and  any  similar  federal,  state  or  local  law,  statute,
regulation,  or  any  common  law  doctrine,  whether  that  dispute  arises  during  or  after
employment, shall be settled by binding arbitration in accordance with the National Rules for
the  Resolution  of  Employment  Disputes  of  the  American  Arbitration  Association;  provided
however,  that  this  dispute  resolution  provision  shall  not  apply  to  any  separate  agreements
between  the  parties  that  do  not  themselves  specify  arbitration  as  an  exclusive  remedy.  The
location  for  the  arbitration  shall  be  the  Philadelphia,  Pennsylvania  metropolitan  area.  Any
award  made  by  such  panel  shall  be  final,  binding  and  conclusive  on  the  parties  for  all
purposes,  and  judgment  upon  the  award  rendered  by  the  arbitrators  may  be  entered  in  any
court  having  jurisdiction  thereof.  The  arbitrators’  fees  and  expenses  and  all  administrative
fees  and  expenses  associated  with  the  filing  of  the  arbitration  shall  be  borne  by  Employer.
The  parties  acknowledge  and  agree  that  their  obligations  to  arbitrate  under  this  Section
survive the termination of this Employment Agreement and continue after the termination of
the  employment  relationship  between  Executive  and  Employer.  The  parties  each  further
agree that the arbitration provisions of this Employment Agreement shall provide each party
with its exclusive remedy, and  each  party  expressly  waives  any  right  it  might  have  to  seek
redress  in  any  other  forum,  except  as  otherwise  expressly  provided  in  this  Employment
Agreement. By election arbitration as the means for final settlement of all claims, the parties
hereby waive their respective rights to, and agree not to, sue each other in any action in
a  Federal,  State  or  local  court  with  respect  to  such  claims,  but  may  seek  to  enforce  in
court  an  arbitration  award  rendered  pursuant  to  this  Employment  Agreement.  The
parties specifically agree to waive their respective rights to a trial by jury, and further
agree that no demand, request or motion will be made for trial by jury.
