Summary of the Material Risks Associated with Our Business

Our business is subject to numerous risks and uncertainties that you should be aware of in evaluating our business. These risks include, but are not limited
to, the following:

<
<

<

<

<

<
<

<

<

<

Our business may be adversely affected by the ongoing coronavirus pandemic.
As  a  company,  we  have  a  limited  operating  history  and  limited  experience  commercializing  pharmaceutical  products  and  have  incurred
significant losses since inception. We expect to incur losses over the next several years and may not be able to achieve or sustain revenues or
profitability in the future.
Although we generate revenue from our first products, Gvoke®, which is available in a pre-filled syringe ("Gvoke PFS") and an auto-injector
("Gvoke HypoPen®"), we have not yet generated revenue from any of our current or future product candidates and may never be profitable.
We may require additional capital to sustain our business, and this capital may cause dilution to our stockholders and might not be available on
terms favorable to us, or at all, which would force us to delay, reduce or eliminate our product development programs or commercialization
efforts.
Our  business  depends  entirely  on  the  success  of  our  products  and  product  candidates.  Even  if  approved,  our  product  candidates  may  not  be
accepted in the marketplace and our business may be materially harmed.
The market opportunity for Gvoke and our product candidates may be smaller than we estimate.
Our reliance on third-party suppliers, including single-source suppliers, and a limited number of options for alternate sources for Gvoke or our
product  candidates  could  harm  our  ability  to  develop  our  product  candidates  or  to  commercialize  Gvoke  or  any  product  candidates  that  are
approved.
Reimbursement  decisions  by  third-party  payors  may  have  an  adverse  effect  on  pricing  and  market  acceptance.  If  there  is  not  sufficient
reimbursement for our products, it is less likely that they will be widely used.
If our third-party manufacturers of Gvoke or our product candidates are unable to increase the scale of their production of our products or our
product  candidates,  or  increase  the  product  yield  of  manufacturing,  then  our  costs  to  manufacture  the  product  may  increase  and
commercialization may be delayed or interrupted.
We expect to seek to establish collaborations and, if we are not able to establish them on commercially reasonable terms, we may have to alter
our development and commercialization plans.
Clinical failure may occur at any stage of clinical development, and the results of our clinical trials may not support our proposed indications
for  our  product  candidates.  If  our  clinical  trials  fail  to  demonstrate  efficacy  and  safety  to  the  satisfaction  of  the  U.S.  Food  &  Drug
Administration  or  other  regulatory  authorities,  we  may  incur  additional  costs  or  experience  delays  in  completing,  or  ultimately  be  unable  to
complete, the development of such product candidate.
Delays  in  conducting  clinical  trials  could  result  in  increased  costs  to  us  and  delay  our  ability  to  obtain  regulatory  approval  for  our  product
candidates.
Gvoke and our product candidates may have undesirable side effects which may delay or prevent marketing approval or, if approval is received,
require them to include safety warnings, require them to be taken off the market or otherwise limit their sales.
We operate in a competitive business environment and, if we are unable to compete successfully against our existing or potential competitors,
our sales and operating results may be negatively affected and we may not successfully commercialize our products or product candidates, even
if approved.
Our success depends on our ability to protect our intellectual property and proprietary technology as well as the ability of our collaborators to
protect their intellectual property and proprietary technology.
It is difficult and costly to protect our intellectual property and our proprietary technologies, and we may not be able to ensure their protection.
Our stock price has been and will likely continue to be volatile, and you may not be able to resell shares of our common stock at or above the
price you paid.

The summary risk factors described above should be read together with the text of the full risk factors below in the section entitled “Risk Factors” and the
other information set forth in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes, as well as in other
documents that we file with the U.S. Securities and Exchange Commission. The risks summarized above or described in full below are not the only risks
that we face. Additional risks and uncertainties not precisely known to us or that we currently deem to be immaterial may also materially adversely affect
our business, financial condition, results of operations and future growth prospects.

PART I

ITEM 1. BUSINESS

Overview

We are a specialty pharmaceutical company delivering innovative solutions to simplify the experience of administering important therapies that people rely
on  every  day  around  the  world.  With  novel  technology  platforms,  XeriSol™  and  XeriJect™,  that  enable  ready-to-use,  room-temperature  stable
formulations of injectable and infusible therapies, we are advancing a portfolio of solutions in various therapeutic categories. Our first product, Gvoke®,
delivers ready-to-use glucagon via a pre-filled syringe ("Gvoke PFS") or auto-injector ("Gvoke HypoPen®") for the treatment of severe hypoglycemia, a
potentially life-threatening condition, in people with diabetes. Gvoke was approved in September 2019 by the U.S. Food & Drug Administration ("FDA")
for the treatment of severe hypoglycemia in pediatric and adult patients with diabetes ages two years and older. We began the field launch of Gvoke PFS
and Gvoke HypoPen in January 2020 and July 2020, respectively, and each is available in two doses: a 0.5 mg/0.1 mL dose for pediatric patients and a 1
mg/0.2 mL dose for adolescent and adult patients. On February 11, 2021 the European Commission ("EC") granted a marketing authorization for Ogluo®
(glucagon) for the treatment of severe hypoglycemia in adults, adolescents, and children aged two years and over with diabetes mellitus. We currently plan
to  commercially  launch  Ogluo  in  select  European  countries  beginning  in  the  fourth  quarter  of  2021.  We  are  also  continuing  to  evaluate  additional
applications  of  our  ready-to-use  glucagon  formulation  to  address  needs  in  hypoglycemia  and  related  conditions.  In  addition,  we  are  applying  our
technology platforms to other commercially available drugs to enable more convenient and patient-friendly subcutaneous ("SC") and intramuscular ("IM")
routes of administration, including the development of products to address unmet needs in both diabetes and epilepsy. We own the rights to our proprietary
formulation  technology  platforms,  Gvoke,  and  our  product  candidates  domestically  and  internationally,  with  117  patents  issued  globally,  including  a
composition  of  matter  patent  covering  our  ready-to-use  glucagon  formulation  that  expires  in  2036.  Throughout  this  document,  unless  otherwise  noted,
references to Gvoke include Gvoke PFS, Gvoke HypoPen and Ogluo.

Our  proprietary  XeriSol  and  XeriJect  non-aqueous  formulation  technologies  have  the  potential  to  offer  distinct  advantages  over  conventional  product
formulations,  including  eliminating  the  need  for  reconstitution  and  refrigeration,  enabling  long-term,  room-temperature  stability,  significantly  reducing
injection  volume,  and  eliminating  the  requirement  for  intravenous  ("IV")  infusion  by  enabling  patient-convenient  SC  or  IM  administration.  With  our
technology, our new product formulations are designed to be easier to use by patients, caregivers, and health practitioners and help reduce costs for payers
and the healthcare system. The target molecules are peptides and small molecules for XeriSol and monoclonal antibodies and biologics for XeriJect. The
formulations  produced  using  these  technologies  can  be  delivered  through  commercially  available  syringes,  auto-injectors,  multi-dose  pens  and  infusion
pumps.  Current  aqueous  formulations  of  certain  drugs  present  numerous  challenges  for  patients  and  caregivers,  including  multi-step  reconstitution,
refrigerated storage, reduced shelf life, large injection volumes, and IV administration over long periods of time. Our formulation technologies have broad
applicability across many therapeutic areas, which we believe could provide more opportunities. There is increasing interest in our technology platforms by
other  drug  development  companies  that  seek  higher  drug  concentrations  and  drug  combinations  in  subcutaneous  forms.  In  addition  to  use  of  these
technologies  for  development  of  our  own  product  candidates,  we  are  currently  conducting  three  technology  platform  collaboration  projects  with  large
pharmaceutical companies. Additional projects are under discussion with both large pharmaceutical and specialized biotech companies.

Our key priority is continuing the successful commercialization of our first product, Gvoke, for the treatment of severe hypoglycemia and increasing the
adoption and penetration of emergency glucagon therapy, by offering a glucagon product that better meets the needs of patients and caregivers. Diabetes is
a  widespread  condition  that  affects  an  estimated  463  million  people  worldwide.  In  the  United  States,  an  estimated  34  million  children  and  adults  have
diabetes, of which 6.8 million are treated with insulin. In the United States, all of the approximately 1.4 million people with Type 1 Diabetes ("T1D") and
5.4 million people with Type 2 Diabetes ("T2D") require insulin therapy to lower their blood glucose levels to achieve normal blood sugar levels and avoid
hyperglycemia. Conversely, insulin treatment in people with both T1D and T2D can also lead to hypoglycemia, a deficiency of glucose in the bloodstream,
which is more common in people with diabetes who are treated with insulin or substances that promote production of insulin. Hypoglycemia is the primary
adverse reaction associated with insulin. However, relative to the number of people on insulin treatment, few prescriptions for glucagon are written. Only
approximately 641,000 prescriptions for glucagon are filled annually. In American Diabetes Association's ("ADA") 2021 Standards of Care guidelines, it is
recommended that glucagon be prescribed for all individuals at increased risk of Level 2 or Level 3 hypoglycemia so that it is available should it be needed.
Level  2  hypoglycemia  is  defined  as  blood  glucose  <54  mg/dl.  Level  3  is  defined  as  a  severe  event  characterized  by  altered  mental  and/or  physical
functioning that requires assistance from another person for recovery.

The  current  standard  of  care  for  severe  hypoglycemia  in  the  ambulatory  setting  is  the  emergency  administration  of  glucagon,  a  hormone  that  raises  the
concentration of glucose in the bloodstream. Traditional glucagon kits consist of a glucagon powder that must be reconstituted with a liquid diluent and
drawn into a syringe using a multi-step procedure that can be difficult to successfully administer, particularly in an emergency. In published comparative
human  factors  studies  with  traditional  glucagon  kits,  only  6%  to  31%  of  users  were  able  to  successfully  administer  the  full  dose  of  glucagon.  In  other
words,  in  these  studies,  test  subjects  failed  to  deliver  the  full  dose  of  glucagon  69%  to  94%  of  the  time.  The  under  use  or  unsuccessful  use  of  these
traditional glucagon kits leaves

5

people at risk of experiencing prolonged severe hypoglycemic events, which, if left untreated, can lead to serious health consequences and death. Due to
the limitations of traditional glucagon kits and other factors, only approximately 465,000 total prescriptions for traditional glucagon kits were written in
2020 in the United States. Annually, hypoglycemic and severe hypoglycemic events in the United States result in approximately $1.8 billion in costs related
to emergency, inpatient and ambulatory care.

Our ready-to-use Gvoke does not require reconstitution or refrigeration and is stable at room temperature for two years. Gvoke is available in either a pre-
filled syringe or an auto-injector with no visible needle. In our human factors studies, 99% of users were able to successfully administer the full dose with
our ready-to-use Gvoke. In addition to Gvoke, Eli Lilly's Baqsimi®, a nasally administered glucagon powder, was approved by the FDA and launched in
2019. These two new, ready-to-use products, Gvoke and Baqsimi, together represented approximately 35% of the total emergency glucagon units dispensed
in the year ended 2020.

Our commercial strategy is to drive awareness with clinicians by targeting high prescribers of mealtime insulin and glucagon to activate demand through
targeted direct-to-patient promotion and patient advocacy groups. Our market access team has secured broad unrestricted access to Gvoke across all payor
types. The combination of our promotional efforts in this category and Eli Lilly’s in support of its Baqsimi are driving a significant increase in prescription
activity for glucagon in general. In fact, since the field launch of Gvoke PFS in January 2020, total glucagon prescriptions across all types and formulations
were higher by 13.1% compared to 2019. According to IQVIA, total prescriptions written in 2020 for Baqsimi and Gvoke were approximately 137,900 and
38,800,  respectively.  Total  units  reported  in  2020  were  approximately  941,000,  representing  total  U.S.  sales  of  $264  million.  These  include  616,000
traditional  glucagon  kits,  251,000  units  of  Baqsimi,  and  74,000  Gvoke  units  (as  adjusted  for  a  consistent  unit  of  measure).  We  believe  that  increasing
penetration, including by new entrants such as Gvoke that address unmet patient and caregiver needs, may result in a potential market opportunity of up to
$3.8 billion.

Outside  the  United  States,  we  estimate  there  are  an  additional  3.5  million  people  with  diabetes  in  Europe  and  an  additional  12.5  million  people  with
diabetes  in  Japan  and  China  that  are  clinically  appropriate  for  emergency  glucagon  treatment.  On  February  11,  2021  the  EC  granted  a  marketing
authorization for Ogluo for the treatment of severe hypoglycemia in adults, adolescents, and children aged two years and over with diabetes mellitus. The
EC  decision  follows  the  positive  opinion  received  from  the  Committee  for  Medicinal  Products  for  Human  Use  ("CHMP")  of  the  European  Medicines
Agency  ("EMA")  in  December  2020.  We  currently  plan  to  commercially  launch  Ogluo  in  select  European  countries  beginning  in  the  fourth  quarter  of
2021. In addition, we expect Gvoke to be available in Israel and the Palestinian Authority in 2022 through our distribution agreement with Megapharm Ltd.
We plan to pursue development and commercialization collaborations for most, if not all, of the non-U.S. markets we seek to enter.

We are also applying our glucagon formulation to other hypoglycemic conditions with significant unmet medical need. In 2020, the following development
programs produced positive clinical trial results:

<

<

Post-Bariatric  Hypoglycemia  ("PBH"),  a  serious  complication  of  bariatric  surgery  that  can  arise  from  excessive  insulin,  or
hyperinsulinism, due to the change in gastric anatomy resulting from bariatric surgery.
Exercise-Induced Hypoglycemia ("EIH") in people with diabetes. Exercise, particularly aerobic exercise, often results in a significant
drop in blood glucose levels for people on insulin.

We  plan  to  advance  at  least  one  of  these  programs  forward.  By  applying  our  ready-to-use  glucagon  to  treat  multiple  conditions,  we  expect  to  leverage
operating efficiencies across our supply chain, research and development, and commercial and medical organizations.

We are also applying our technology platforms to develop additional product candidates, such as a fixed ratio co-formulation of pramlintide and insulin
("Pram-Insulin")  for  the  management  of  diabetes  and  a  ready-to-use,  liquid-stable  diazepam  delivered  via  an  injectable  rescue  pen  for  the  emergency
treatment of epileptic seizures. Additionally, we believe we have the potential to advance a number of programs in other indications based on the promising
data we have seen from formulations in our laboratory as well as from an early clinical trial. We also believe that our strong product candidate portfolio,
complemented by external expansion opportunities, will support our vision to effectively and efficiently meet the needs of our target markets. Both the
Pram-Insulin and diazepam programs produced positive clinical trial results in 2020, and in October 2020 we were granted Fast Track designation by the
FDA for our diazepam formulation. We have identified these two programs as candidates for out-licensing.

The nature of our product candidates and target conditions provides us with a potentially faster and capital-efficient development and regulatory pathway to
approval.  The  FDA  has  granted  orphan  drug  status  to  several  indications  for  our  product  candidates,  including  our  ready-to-use  glucagon  for  PBH  and
Congenital Hyperinsulinism ("CHI") and our ready-to-use, liquid-stable formulation of diazepam for the treatment of Dravet syndrome and acute repetitive
seizures  ("ARS")  in  patients  with  epilepsy.  Additionally,  we  have  received  orphan  drug  designation  from  the  EMA  for  CHI  Noninsulinoma
Pancreatogenous Hypoglycemia Syndrome ("NIPHS"), which includes patients with PBH.

In the United States, this designation provides us with research and development tax credits and exemption from FDA user fees, as well as seven years of
orphan  drug  exclusivity  upon  product  approval.  In  the  European  Union  ("EU"),  this  designation  provides  us  with  ten  years  of  market  exclusivity  upon
product approval and a single MAA application to the EMA through centralized review and

6

 
 
the potential for reduced regulatory review fees. In addition, because certain conditions that we intend to target are rare conditions, we believe our clinical
trials  may  be  of  smaller  size  than  studies  for  conditions  that  are  not  rare  conditions.  Furthermore,  because  the  product  candidates  developed  using  our
technology platforms are designed to be reformulations of currently approved products, in the United States, for most of our products, we expect to utilize
the FDA’s pathway under Section 505(b)(2) of the U.S. Federal Food, Drug and Cosmetic Act ("FDCA") which permits submissions to rely, in part, on the
safety and effectiveness of a previously approved product, which may potentially result in a more expeditious pathway to FDA approval.

Our  management  team  includes  veterans  in  drug  development,  discovery  and  commercialization,  with  executive  experience  in  leading  global
pharmaceutical  and  healthcare  companies,  including  Durata  Therapeutics,  Baxter  Healthcare,  Merck,  Searle,  Takeda,  Warner  Chilcott,  MedPointe
Healthcare, Amgen, Amylin Pharmaceuticals, PowderJect Technologies and Alpharma.

Our Strategy

Our  strategy  is  to  utilize  our  proprietary  non-aqueous  formulation  technology  platforms  to  convert  marketed  and  development-stage  products  that  have
poor  solubility  and  stability  into  ready-to-use,  user-friendly  injectable  and  infusible  drugs  for  multiple  therapeutic  areas  and  conditions,  including
hypoglycemia,  diabetes,  epilepsy,  gastroenterology  and  endocrinology.  We  also  seek  to  apply  our  formulation  technology  platforms  to  enhance  the
formulations of proprietary products and candidates of other pharmaceutical and biotechnology companies. The key elements of our strategy include:

Maximize the commercial potential of Gvoke. We began the field launch of Gvoke PFS and Gvoke HypoPen in the United States in
January  2020  and  July  2020,  respectively.  We  are  targeting  healthcare  professionals  who  are  high  prescribers  of  glucagon  and/or
mealtime  insulin  products,  using  both  field  and  inside  sales  teams,  engaging  with  professional  associations,  and  activating  demand
through targeted direct-to-patient promotion and patient advocacy groups.
Launch our ready-to-use liquid stable glucagon in Europe. On February 11, 2021 the EC granted a marketing authorization for Ogluo
for the treatment of severe hypoglycemia in adults, adolescents, and children aged two years and over with diabetes mellitus. The EC
decision  follows  the  positive  opinion  received  from  the  CHMP  of  the  EMA  in  December  2020.  We  currently  plan  to  commercially
launch our liquid glucagon formulation as Ogluo in select European countries beginning in the fourth quarter of 2021. In addition, we
expect Gvoke to be available in Israel and the Palestinian Authority in 2022 through our distribution agreement with Megapharm Ltd.
We plan to pursue development and commercialization collaborations for most, if not all, of the non-U.S. markets we seek to enter.
Continue to advance our ready-to-use glucagon portfolio to address hypoglycemia associated with other conditions. We are applying
our  ready-to-use,  room-temperature  stable  liquid  glucagon  formulation  to  other  hypoglycemic  conditions  for  non-rescue  indications,
such as PBH and EIH. The product presentation for these two indications is a vial of our liquid glucagon for self-administration via a
syringe  or  transfer  to  a  pump  reservoir  for  continuous  infusion.  Additionally,  we  have  completed  preclinical  studies  for  a
gastroenterology indication. We plan to leverage efficiencies across our portfolio, such as our supply chain, research and development,
and  our  commercial  and  medical  organizations,  and  to  use  commercially  available  drug  delivery  devices  for  our  liquid  glucagon
formulation programs.
Continue to leverage our technology and expertise to develop a portfolio of non-glucagon product candidates. We are also applying
our formulation technology platforms to other commercially available drugs for multiple conditions. We completed a Phase 2 clinical
trial of our fixed-ratio pramlintide-insulin co-formulation combination product for the treatment of diabetes, from which we announced
positive topline results. In addition, we are developing an improved formulation of diazepam to be administered through a ready-to-use
injectable rescue pen for which we are evaluating indications such as the treatment of patients with Dravet syndrome and ARS. In 2019,
we completed a clinical study evaluating the preclinical pharmacokinetic ("PK") and pharmacodynamics ("PD") of our ready-to-use,
room-temperature stable liquid diazepam formulation in normal volunteers and announced positive results. Based on these results, we
initiated  and  completed  an  additional  Phase  1b  weight-based  study,  in  which  we  announced  positive  topline  results  in  July  2020.  In
October  2020,  we  were  granted  Fast  Track  designation  by  the  FDA  for  our  novel  formulation  of  diazepam,  which  could  advance
directly  into  a  Phase  3  registration  study  in  both  pediatric  and  adult  patients  with  epilepsy.  Finally,  we  have  completed  preclinical
development for an additional product candidate in endocrinology.
Collaborate with pharmaceutical and biotechnology companies to apply our technology platforms to enhance the formulations of
their  proprietary  products  and  candidates.  We  are  pursuing  formulation  and  development  partnerships  to  apply  our  XeriSol  and
XeriJect  technology  platforms  to  enhance  the  formulation,  delivery  and  clinical  profile  of  other  companies’  proprietary  drugs  and
biologics. We currently are working with some major pharmaceutical companies on feasibility programs to evaluate the formulation of
their proprietary therapeutics with XeriSol or XeriJect. We plan to continue to explore the application of our formulation technology
platforms to proprietary drugs and biologics from additional pharmaceutical and biotechnology companies. Our strategic goal is to enter
into broader development agreements with these partners upon successful completion of the feasibility programs. Such agreements may
provide the potential for milestone payments and royalty streams.

Our Technology Platforms

Overview

Our proprietary non-aqueous formulation technology platforms are designed to address the challenges presented by current aqueous formulations of certain
drugs. Injectable pharmaceuticals have conventionally used aqueous delivery systems to administer drugs and biologics, but, in the presence of water, many
drugs  have  poor  solubility  and  low  stability.  To  optimize  their  stability  and  enable  longer-term  storage,  many  of  these  products  are  freeze  dried  into  a
powder  and,  when  needed,  must  be  reconstituted  with  a  liquid  diluent,  which  is  often  a  challenging  multi-step  procedure  with  the  potential  for  error.
Furthermore, the drug product begins to break

8

down  once  combined  with  water,  which  requires  the  drug  to  be  used  immediately  or  otherwise  refrigerated.  In  addition,  these  products  can  require
complicated formulations and large injection volumes to make them soluble. For many products, these volumes are too large for SC or IM delivery and
instead necessitate IV infusion over several hours. These drugs can be difficult or painful to administer and have limited portability, resulting in an overall
poor experience for patients and caregivers.

Our  proprietary  XeriSol  and  XeriJect  platforms  offer  the  opportunity  to  eliminate  the  need  for  reconstitution  and  refrigeration,  enable  long-term  room-
temperature  stability,  significantly  reduce  injection  volume  and  allow  for  a  more  convenient  SC  or  IM  administration  as  opposed  to  IV  infusion,  all  of
which we believe are distinct advantages over existing aqueous formulations of marketed products and development-stage product candidates. We believe
that our technology platforms can lead to products that will improve outcomes and enable easier administration while reducing costs for payors and the
healthcare system.

Our  XeriJect  formulation  platform  is  best  suited  for  drugs  and  biologics  consisting  of  large  molecules,  such  as  proteins,  monoclonal  antibodies  and
vaccines. XeriSol is best suited for peptides and small molecules that currently encounter formulation challenges. With XeriJect, we routinely formulate
suspensions with a protein concentration in excess of 400 mg/mL, far exceeding current aqueous formulation systems with maximum achievable protein
concentrations of 50-250 mg/mL. These biocompatible non-aqueous, injectable solutions or suspensions formulated using our technology platforms can
then be packaged for administration in a commercially available auto-injector, pre-filled syringe, vial, multi-dose pen or infusion pump.

Ready-to-Use Glucagon

Our novel, room-temperature stable liquid glucagon formulation represents a significant advancement over freeze-dried, or lyophilized, glucagon, enabling
a ready-to-use solution that can be quickly and easily injected or infused subcutaneously. This formulation is designed to provide the flexibility to dose
different volumes of liquid glucagon using a range of delivery devices to suit the needs of people with hypoglycemic conditions. We believe our ready-to-
use  glucagon  has  the  potential  to  change  the  paradigm  for  the  treatment  of  hypoglycemic  conditions  and  improve  the  lives  of  people  who  experience
hypoglycemia.

Our Products

Gvoke

Gvoke  offers  ready-to-use,  room-temperature  stable  glucagon  that  is  designed  to  be  administered  subcutaneously  in  a  simple  two-step  process  via  a
commercially available pre-filled syringe or auto-injector. In our human factors studies, 99% of users were able to successfully administer the full dose
with either Gvoke PFS or Gvoke HypoPen. Conversely, in published human factors studies of traditional emergency liquid glucagon kits, only 6% to 31%
of  users  were  able  to  successfully  administer  the  full  dose.  We  believe  we  can  establish  Gvoke  as  the  preferred  emergency  glucagon  product  and  drive
greater adoption and penetration of emergency glucagon therapy for patients and caregivers. Gvoke was approved in September 2019 by the FDA for the
treatment of severe hypoglycemia, a potentially life-threatening condition, in pediatric and adult patients with diabetes ages two years and older. We began
the  field  launch  of  Gvoke  PFS  and  Gvoke  HypoPen  in  January  2020  and  July  2020,  respectively.  Both  presentations  are  available  in  two  doses:  a  0.5
mg/0.1 mL dose for pediatric patients and a 1 mg/0.2 mL dose for adolescent and adult patients.

On February 11, 2021 the EC granted a marketing authorization for Ogluo for the treatment of severe hypoglycemia in adults, adolescents, and children
aged two years and over with diabetes mellitus. The EC decision follows the positive opinion received from the CHMP of the EMA in December 2020. We
currently plan to commercially launch Ogluo in select European countries beginning in the fourth quarter of 2021. We plan to pursue development and
commercialization collaborations for most, if not all, of the non-U.S. markets we seek to enter.

Hypoglycemia Background

Diabetes is a widespread condition that affects an estimated 463 million people worldwide with an estimated 22 million drug-treated people in the United
States. Among people with diabetes in the United States, all of the approximately 1.4 million people with T1D and 5.4 million people with T2D require
insulin therapy to lower their blood glucose levels to achieve normal blood sugar levels and avoid hyperglycemia. Conversely, insulin treatment in people
with diabetes can also lead to hypoglycemia, a deficiency of glucose in the bloodstream, which is more common in people with diabetes who are treated
with insulin or substances that promote production of insulin. Hypoglycemia is the primary adverse reaction associated with insulin.

9

Hypoglycemia  is  categorized  by  level  of  severity,  expressed  as  mild,  moderate  or  severe  hypoglycemic  events.  Definitions,  symptoms  and  treatment
recommendations  for  hypoglycemia  per  the  ADA  and  the  American  Association  of  Clinical  Endocrinologists  ("AACE")  are  summarized  in  the  figure
below:

Hypoglycemic events of any severity are a daily concern for people with diabetes. Severe hypoglycemic events are extremely frightening for patients and
caregivers and can result in cardiovascular disease, seizure, coma, and, if left untreated, death. Fear of hypoglycemia and the morbidity and mortality risks
associated  with  it  are  a  constant  reality  for  people  with  diabetes.  According  to  scientific  literature,  fear  of  hypoglycemia  is  a  critical  impediment  to
psychological well-being and quality of life and represents the greatest barrier to optimal glycemic control. Studies have shown that only 14% of those
aged 18–25 years and 29% of those aged 26–50 years achieved optimal glycemic control by taking insulin.

The ADA recommends that glucagon be prescribed for all individuals at increased risk of Level 2 or Level 3 hypoglycemia so that it is available should it
be needed. Glucagon works to raise the glucose levels in a person’s blood by inducing the liver to convert glycogen, a type of stored sugar in the body, into
glucose.

While patients can take preventive measures, hypoglycemic events still occur. On average, people with T1D experience an episode of mild or moderate
hypoglycemia twice per week and 30% to 40% of people with T1D experience one to three episodes of severe hypoglycemia per year. On average, half of
people with T2D treated with insulin experience an episode of mild or moderate hypoglycemia and 20% experience at least one severe episode a year.

10

Risks associated with severe hypoglycemia are greater than other highly treated medical conditions in the U.S., as summarized in the figure below:

Limitations of Existing Emergency Liquid Glucagon Kits

®

Because  of  the  urgent  nature  of  severe  hypoglycemia,  the  majority  of  severe  hypoglycemic  events  are  treated  on  an  emergency  basis,  outside  of  a
healthcare facility. Prior to the FDA's approval of Gvoke in September 2019 and Eli Lilly's Baqsimi in July 2019, a nasally administered glucagon powder,
there  were  only  two  emergency  glucagon  products  available  to  treat  severe  hypoglycemia:  Eli  Lilly’s  Glucagon  Emergency  Kit  ("GEK")  and  Novo
Nordisk’s GlucaGen  HypoKit . Each of these products is sold as a vial of lyophilized glucagon powder with an exposed needle/syringe that contains a
liquid diluent. The glucagon powder must be combined with the liquid diluent at the time of use and drawn into a syringe in accordance with a complex
multi-step reconstitution and dose calibration procedure. Long-term storage of the combined solution is impractical because once the lyophilized glucagon
is combined with water, the solution becomes unstable and can fibrillate, rendering it inactive and potentially toxic. The multi-step reconstitution and dose
calibration procedure required for traditional glucagon kits can be intimidating, particularly in an emergency situation, for likely glucagon kit users, a group
that includes caregivers, co-workers, friends, teachers or other bystanders.

®

In 2018, we conducted a quantitative study with 700 caregivers and people with diabetes evaluating the market perceptions of traditional glucagon kits,
which  we  refer  to  as  our  Caregiver  and  Patient  Perceptions  Study.  In  that  study,  only  one  third  of  respondents  had  a  highly  favorable  opinion  of  the
traditional kits and only half were confident that a glucagon kit user would be able to correctly administer the traditional emergency glucagon products.
Furthermore, in three published comparative human factors studies with traditional kits, only 6% to 31% of users were able to successfully administer the
full dose of glucagon. In other words, in these studies, test subjects failed to deliver the full dose of glucagon 69% to 94% of the time. Accordingly, a
diabetes patient experiencing a severe hypoglycemic episode who relies on a bystander to administer glucagon may not receive the full dose of glucagon
needed to restore their blood glucose levels. Failure to promptly treat severe hypoglycemia leaves the person at critical risk of irreversible brain damage
and  heart  problems,  especially  in  people  who  already  have  coronary  artery  disease.  If  emergency  medical  treatment  is  not  successful,  the  severe
hypoglycemic event can be fatal.

Of  the  units  of  glucagon  rescue  products  dispensed  in  the  U.S.  in  2020,  Eli  Lilly's  GEK  and  Baqsimi  represented  approximately  50%  and  27%,
respectively, Novo Nordisk's GlucaGen HypoKit represented approximately 14%, Gvoke represented approximately 8% and Fresenius Kabi's Glucagon
Emergency Kit represented approximately 1%.

Xeris Gvoke Key Features and Benefits

Leveraging our patented XeriSol technology, we believe Gvoke offers an important advancement in the treatment of severe hypoglycemia. Gvoke is the
first ready-to-use, room-temperature stable liquid glucagon product approved that can be administered via a pre-filled syringe (Gvoke PFS) or auto-injector
(Gvoke HypoPen). Gvoke PFS and Gvoke HypoPen are currently available in two doses: a 0.5 mg/0.1 mL dose for pediatric patients and a 1 mg/0.2 mL
dose for adolescent and adult patients. These innovative formats are designed to provide the reliability of a ready-to-use liquid glucagon while allowing
patients or caregivers to administer it quickly and simply.

The key features of Gvoke PFS and Gvoke HypoPen are:

<

<

<

<

Ready-to-use: With its two-step administration process, the user of Gvoke HypoPen, pulls off the cap and pushes down on the skin for
five seconds until the viewing window turns red, or with Gvoke PFS, pulls off the cap, inserts the needle at a 90-degree angle and
pushes the plunger down as far as it will go. There is no reconstitution required at the time of emergency.
Reliable administration: In our human factors studies, 99% of users were able to successfully administer the full dose.
No dose calibration required: Gvoke is offered in two pre-measured doses: 0.5 mg/0.1 mL dose for pediatric patients and 1 mg/0.2 mL
dose for adolescent and adult patients.
Two-year room-temperature stability: No refrigeration is required at any time.

In addition, key features specific to the Gvoke HypoPen are:

<

<

<

No visible needle: The needle in the Gvoke HypoPen is not visible to the user.
Auto-retraction: The needle auto-retracts after administration for safety.
Auto-locks: The device auto-locks after use for safety.

In contrast to traditional glucagon kits, Gvoke features the following benefits:

1. Biodel (Diabetes Tech Meeting, October 2015) – GEM; Locemia/Lilly (EASD 2015 Poster) – Intranasal; and Xeris Comparative Human Factors (ATTD
Meeting, February 2016); 2. Brett Newswanger, Steven Prestrelski & Anthony D. Andre (2019) Human factors studies of a prefilled syringe with stable
liquid  glucagon 
in  a  simulated  severe  hypoglycemia  rescue  situation,  Expert  Opinion  on  Drug  Delivery,  16:9,  1015-1025,  DOI:

a glucagon autoinjector in a simulated severe hypoglycemia rescue situation. Diabetes Technol Ther. 2019;21(9):522-530.

In our Caregiver and Patient Perceptions Study conducted in 2018, more than 75% of subjects responded that they would prefer Gvoke HypoPen over the
then-existing traditionally available glucagon kits. Also in 2018, we conducted a quantitative study of over 400 healthcare professionals, which we refer to
as our Healthcare Professional Perceptions Study. In that study, results indicated that glucagon would be prescribed to more people across all clinically
appropriate  patient  segments  if  Gvoke  HypoPen  was  available.  Based  on  this  market  research,  we  believe  that  the  glucagon  market  will  become  more
penetrated and that Gvoke HypoPen will become the preferred emergency glucagon delivery solution.

Xeris Gvoke Market Potential

Based  on  current  market  data  as  well  as  our  Caregiver  and  Patient  and  Healthcare  Professional  Perceptions  Studies,  we  believe  that  Gvoke  has  the
opportunity to increase penetration of the glucagon market in severe hypoglycemia by increasing the number of people with diabetes who have a filled
glucagon prescription and by increasing the number of glucagon rescue devices they have on hand.

There are approximately 22 million drug-treated people with diabetes in the United States, and the compound annual growth rate in incidence of diagnosed
and treated people with diabetes is approximately 4% per year. An additional 88 million people in the United States are pre-diabetic and may progress to
T2D. The ADA recommends that glucagon be prescribed for all individuals at increased risk of Level 2 or Level 3 hypoglycemia so that it is available
should  it  be  needed.  Based  on  our  Healthcare  Professional  Perceptions  Study,  we  believe  all  people  on  insulin  are  considered  clinically  appropriate  for
glucagon. In the United States, there is an estimated 1.4 million people with T1D who are treated with insulin because their bodies do not naturally produce
insulin  and  approximately  5.4  million  additional  people  with  T2D  who  are  treated  with  insulin  because  their  bodies  do  not  use  insulin  properly.  In  the
aggregate, we estimate that the potential target population for emergency glucagon therapy totals approximately 6.8 million people in the United States. We
believe every person who is on insulin therapy should have ready-to-use glucagon available for a potential severe hypoglycemic episode. With such an
expansion in glucagon prescriptions, and also by increasing penetration into the market for emergency glucagon kits, the U.S. potential market opportunity
may be up to $3.8 billion.

13

Despite  the  risk  of  experiencing  a  severe  hypoglycemic  event,  we  believe  that  emergency  glucagon  therapy  is  under-appreciated,  under-evaluated  and
under-taught, resulting in a market that is underpenetrated. According to a 2015 study published in the journal Endocrine Practice, approximately 50% of
people  with  T1D  and  approximately  3%  of  people  with  T2D  with  a  new  insulin  prescription  had  a  filled  glucagon  prescription.  We  believe  that  the
drawbacks of traditional kits and the lack of conversations regarding glucagon limit their adoption. Two of the top reasons given by people with diabetes
for non-renewal of glucagon prescriptions were that they were not confident that a caregiver or other person would be able to correctly administer the kit,
and  their  healthcare  professional  did  not  discuss  the  need  for  a  new  one  with  them.  In  the  United  States,  approximately  465,000  total  prescriptions  for
emergency glucagon kits were written in 2020 in the United States, resulting in the purchase of approximately 616,000 single-dose kits. In 2020, a total of
941,000 units of emergency glucagon products were dispensed in the U.S., representing total sales of approximately $264 million.

In  our  Healthcare  Professional  Perceptions  Study,  results  indicated  that  glucagon  would  be  prescribed  to  more  people  across  all  clinically  appropriate
patient segments if our Gvoke HypoPen were available. Similarly, in our Caregiver and Patient Perceptions Study, almost two-thirds of people with T1D
and T2D who use insulin said they would proactively ask for a prescription for Gvoke HypoPen if available. Importantly, over half of those same people
did  not  currently  have  a  filled  glucagon  prescription.  During  an  emergency  hypoglycemic  event,  these  individuals  would  often  be  required  to  seek
treatment through ambulance calls, hospital admissions or office visits. We believe that these studies show that more people would want to have emergency
glucagon on-hand if there was a product that better met their needs. We believe this represents an opportunity for Gvoke to shift the site of care from the
emergency room or hospital to less costly settings such as the home.

Outside the United States, we estimate that an additional 3.5 million people with diabetes in Europe and an additional 12.5 million people with diabetes in
Japan and China are clinically appropriate for glucagon treatment. However, in 2018, only approximately 733,000 emergency glucagon products were sold
in the United Kingdom, Germany, France, Italy and Spain combined, and only approximately 4,000 were sold in Japan and China combined, which we
believe indicates that the market for emergency glucagon products is significantly underpenetrated in those regions.

Commercial Strategy

Our  commercial  strategy  is  to  increase  the  number  of  people  on  insulin  therapy  who  have  emergency  glucagon  products  available.  Our  sales  force  is
focused on driving awareness and adoption of Gvoke by healthcare professionals.

We began the field launch of Gvoke PFS in January 2020 and Gvoke HypoPen in July 2020. Our strategy for Gvoke includes the following:  

<

<

<

Drive awareness, adoption and utilization of Gvoke. We plan to drive awareness and adoption of Gvoke to expand glucagon adoption.
o Healthcare  Professionals:  We  are  targeting  certified  diabetes  care  and  education  specialists  and  high  insulin  and  glucagon

prescribing healthcare professionals. We are reaching these professionals using our field and inside sales teams.
Patients and Caregivers: We are activating patients through patient advocacy organizations and leveraging channels such as direct-
to-consumer advertising, patient influencer content, digital presence, traditional off-line channels, social media and press coverage to
drive awareness and communicate our value proposition to patients and caregivers.

o

Penetrate the market. We believe that the Gvoke market is currently significantly underpenetrated due to the lack of, and limitations in,
current treatment options. We have designed Gvoke to offer healthcare professionals, patients and caregivers a ready-to-use alternative
that  facilitates  administration  of  the  full  dose  of  glucagon  every  time  it  is  used.  We  believe  this  product  offering,  paired  with  our
commercial focus, has the potential to grow the market in two ways:
o Healthcare Professionals: In addition to certified diabetes care and education specialists and high insulin and glucagon prescribing
healthcare professionals, we are targeting healthcare professionals who are high mealtime insulin prescribers but who are not high
prescribers of glucagon. We are reaching these professionals using our field and inside sales teams.
Patients and Caregivers: We believe there are opportunities to activate patient and caregiver demand for Gvoke. Gvoke is designed
as a ready-to-use solution for a segment of patients and caregivers who currently lack the confidence in administering traditional
emergency glucagon kits and would rather rely on emergency responders for treatment.

o

Promote  access.  Approximately  80%  of  all  patients  currently  have  unrestricted  access  to  Gvoke.  Of  our  target  patient  population,
approximately  60%  are  commercially  insured,  approximately  20%  are  covered  by  Medicare  and  approximately  20%  are  covered  by
Medicaid and other government programs. We plan to continue our focus on promoting access to Gvoke. We have engaged with payors
to more fully understand their drivers and barriers and convey the health and pharmacoeconomic value of Gvoke.

14

<

Impact of COVID-19 pandemic. We believe that customer demand has been adversely impacted by the COVID-19 pandemic. Initially,
we suspended in-person interactions by our sales and marketing personnel in healthcare settings. We are engaging with these customers
remotely, via webinar programs and virtual meetings, as we seek to continue to support healthcare professionals and patient care. As parts
of  the  United  States  reopened,  some  of  our  sales  and  marketing  personnel  began  to  reengage  with  a  limited  number  of  in-person
interactions.  However,  with  the  resurgence  of  COVID-19  in  many  areas,  our  ability  to  connect  with  our  customers  in  person  became
much  more  limited  and  we  are  currently  back  to  almost  exclusively  remote  interactions.  In  addition,  several  conferences  and  other
programs  at  which  we  intended  to  market  Gvoke  have  been  postponed,  canceled  and/or  transitioned  to  virtual  meetings.  Remote
interactions may be less effective than in-person interactions. We have also revised our patient copay assistance program to offer a copay
card with a buy-down to $0 for commercially eligible patients in response to the COVID-19 pandemic.

We have established a distribution channel in the United States for the commercialization of Gvoke, which is currently being sold primarily to wholesale
pharmaceutical distributors, who, in turn, sell Gvoke to pharmacies and other customers. We use a third-party logistics provider for key services related to
logistics,  warehousing  and  inventory  management,  distribution,  contract  administration,  order  management  and  chargeback  processing  and  accounts
receivable management. Outside the United States, we plan to collaborate with local companies.

Our Product Candidates

Ready-to-Use Glucagon for Other Hypoglycemia Conditions

We  are  applying  our  ready-to-use  liquid-stable  glucagon  formulation  to  treat  other  hypoglycemic  conditions  with  significant  unmet  medical  need.  In
particular,  our  formulation  may  be  applied  to  conditions  requiring  continuous  doses  or  smaller  "mini-doses"  of  glucagon  over  a  longer  administration
period. We intend to leverage work across our programs to substantially reduce development costs for each indication and enable expanded uses for our
ready-to-use glucagon to follow Gvoke. Development aspects that can be leveraged include:

<

<

<

Chemistry, manufacturing and controls ("CMC")
Nonclinical toxicology program
Clinical supplies manufacturing

For other hypoglycemic conditions, we intend to leverage our completed preclinical studies across our glucagon portfolio, which demonstrated the safety of
the  ready-to-use  glucagon  and  supported  further  clinical  development.  We  have  been  awarded  a  $1.0  million  grant  from  the  Leona  M.  and  Harry  B.
Helmsley Charitable Trust for preclinical studies of glucagon product candidates for sub-chronic/chronic conditions.

For  commercialization  of  ready-to-use  glucagon  for  certain  other  hypoglycemic  conditions,  we  expect  to  target  endocrinologists,  diabetologists  and
primary care providers that are currently prescribing glucagon and rapid acting insulin. Many of these physicians, particularly endocrinologists, are also
currently treating PBH patients and we believe there is significant overlap between these physicians and those who would prescribe ready-to-use glucagon
for diabetes.

In December 2013, we filed an IND application for the use of ready-to-use glucagon delivered via a wearable patch pump. This IND has supported our
clinical development efforts in PBH and an assessment in a bi-hormonal artificial pancreas closed-loop system. We are the sponsor of this IND, which is
active as of the date of this Annual Report on Form 10-K.

Ready-to-Use Glucagon for Post-Bariatric Hypoglycemia

We are developing a ready-to-use glucagon formulation for chronic self-administration in PBH, a challenging complication of bariatric surgery that may
significantly impair quality of life, but for which there are currently no approved treatments. In January 2018, we received orphan drug designation from
the FDA for our ready-to-use glucagon for the treatment of patients with hyperinsulinemic hypoglycemia, of which PBH is a category. In November 2018,
we received EU orphan product designation for the treatment of NIPHS which includes patients with PBH.

Post-Bariatric Hypoglycemia Market

Obesity and related comorbidities such as T2D and cardiovascular disease are increasingly recognized as a major threat to individual and public health,
with sustained weight loss difficult to achieve. Clinicians and patients alike have embraced the results of recent controlled clinical trials demonstrating the
efficacy of surgical procedures performed on the stomach or intestines, known as bariatric surgery, to not only induce sustained weight loss but also to
improve  or  normalize  obesity-related  comorbidities,  including  T2D.  The  number  of  bariatric  surgeries  performed  in  the  United  States  has  increased
substantially from an estimated 158,000 procedures per year in 2011 to 252,000 in 2018. While benefits of bariatric surgery are now achieved with a lower
risk of surgical complications, longer-term intestinal and nutritional complications can still occur.

15

 
 
One  challenging  and  sometimes  severe  complication  of  bariatric  surgery  is  hyperinsulinemic  hypoglycemia.  Hyperinsulinemic  hypoglycemia,  and  more
specifically PBH, is most commonly associated with Roux-en-Y gastric bypass ("RYGB"), a procedure in which the small intestine is re-routed to a small
resected stomach pouch. However, PBH also has been observed following sleeve gastrectomy, a procedure that reduces the size of the stomach. In the U.S.,
approximately 17% of bariatric procedures performed are RYGB, while approximately 61% are sleeve gastrectomy. PBH is defined as documented plasma
glucose levels below 70 mg/dL in conjunction with hypoglycemic symptoms and the relief of such symptoms with the normalization of glucose levels.
Symptoms include palpitations, lightheadedness and sweating. A subset of post-bariatric surgery patients develops very severe hypoglycemia involving a
shortage of glucose in the brain, known as neuroglycopenic symptoms, typically occurring one to three years following bariatric surgery and associated
with confusion, decreased attentiveness, seizure and loss of consciousness. For these patients, quality of life can be severely affected as many cannot care
for themselves or even be left alone and may ultimately lose their employment due to this disability.

Hypoglycemia typically occurs after meals, particularly those rich in simple carbohydrates. Due to the change in gastric anatomy resulting from bariatric
surgery,  plasma  insulin  concentrations  are  inappropriately  high  after  meals,  which  can  lead  to  severe  hypoglycemia  in  these  patients.  Treatment  of
hypoglycemia requires rapid-acting carbohydrates such as glucose tablets, which in PBH patients can contribute to rebound hyperglycemia that triggers
further insulin secretion and recurrent hypoglycemia.

There  are  currently  no  approved  treatments  for  PBH.  Current  strategies  to  manage  PBH  include  dietary  modification  aimed  at  reducing  intake  of  high
glycemic index carbohydrates. Both diet and off-label administration of pre-meal acarbose, an anti-diabetic drug used to treat T2D, aim to minimize rapid
post-meal surges in glucose that trigger insulin secretion. Additional off-label therapies include those aimed at reducing insulin secretion. In severe cases,
gastric restriction or banding has been required to slow gastric emptying, and gastrostomy tubes have been used to provide the sole source of nutrition.
Despite strict adherence to medical nutrition therapy and clinical use of multiple medical options, patients continue to have frequent hypoglycemia. While
hypoglycemia most commonly occurs following meals, it can also occur in response to increased activity and emotional stress. Importantly, patient safety is
additionally  compromised  when  hypoglycemia  unawareness  develops  with  recurrent  hypoglycemia.  We  believe  there  is  an  urgent  need  for  therapeutic
options to allow optimal nutrition, maintain health and quality of life and improve safety in patients with PBH.

Because episodes of hypoglycemia normally occur in the ambulatory setting, the reported prevalence of PBH varies, but we estimate that roughly 1% to
2% of bariatric surgery patients experience PBH. As bariatric procedures have been performed for over ten years, based on our analysis of market research,
we estimate a standing population of approximately 85,000 patients who fail mealtime nutritional therapy and experience PBH in the United States and
require additional treatment options. A similar size patient population is estimated to exist in Europe. Depending on the severity of their condition, these
patients may require chronic episodic administration of glucagon ranging from multiple times a month to multiple times a day.

Xeris Offering–Ready-to-Use Glucagon for PBH

We have developed a ready-to-use glucagon formulation that can be easily and quickly injected or infused subcutaneously from a syringe, pen or pump.
Injection  of  small  doses  of  our  liquid-stable  glucagon  after  meals  may  offer  a  novel  mechanism  for  PBH  patients  to  treat  or  prevent  hypoglycemia.
Importantly, these smaller and more physiologic doses are designed to prevent rebound hyperglycemia associated with glucose tablets, carbohydrate intake
and rescue doses of glucagon. Further, small doses of glucagon may offer a direct treatment mechanism for PBH, as opposed to indirect methods aimed at
preventing hypoglycemia that are currently employed using various off-label therapeutic options.

Primary market research has shown endocrinologists are comfortable with glucagon’s mechanism of action and current safety profile and view ready-to-use
glucagon as a welcome treatment option for PBH patients. Physicians surveyed reported ready-to-use glucagon utilization of 35% to 59% if the product can
prevent half of severe hypoglycemic events in PBH patients.

As there are currently no therapeutic options indicated for treatment of PBH and the condition has been designated a rare disease, we believe that payors
will  include  our  ready-to-use  glucagon  on  their  formularies,  if  approved.  We  intend  to  conduct  additional  payor  research  as  product  development
progresses.

Clinical Experience in PBH

We have completed a proof-of-concept clinical trial and a randomized controlled Phase 2 clinical trial for our ready-to-use glucagon for the treatment of
PBH.  A  new  IND  application  for  self-administration  of  our  ready-to-use  glucagon  with  a  vial/syringe  went  into  effect  on  October  19,  2018.  This  IND
authorized  us  to  initiate  an  additional  Phase  2  trial  evaluating  our  ready-to-use,  room-temperature  stable  liquid  glucagon  formulation  for  patients  who
experience  hyperinsulinemic  hypoglycemia  after  bariatric  surgery.  We  received  positive  top-line  results  from  the  in-clinic  and  outpatient  phases  of  this
Phase 2 clinical trial.

Phase 2 Clinical Trials

XSGO-PB01: A Phase 2 Proof-Of-Concept Study of Sensor Guided, Clinician-Administered Delivery of Glucagon Infusion from a Patch Pump
to Prevent Post-Prandial Hypoglycemia in Post-Bariatric Surgery Patients

We conducted an iterative design-and-evaluation Phase 2 clinical trial to assess the performance of a novel event-based hypoglycemia prediction algorithm
that triggered delivery of mini-doses of ready-to-use glucagon from a patch pump. For the trial, which was conducted from the first quarter of 2016 through
the second quarter of 2017, we recruited seven patients 18 to 65 years of age with a history of RYGB surgery and PBH with neuroglycopenia who were
uncontrolled  on  medical  nutrition  therapy  and  medications.  In  an  inpatient  setting,  subjects  received  a  mixed-meal  tolerance  test  ("MMTT"),  which  is
known  to  cause  hypoglycemia  in  these  patients.  Upon  receipt  of  an  alarm  based  on  continuous  glucose  monitor  data,  subjects  were  given  small,
subcutaneous  infusions  of  ready-to-use  glucagon  from  a  pump,  with  the  aim  of  preventing  hypoglycemia.  The  primary  endpoint  of  this  study  was  to
investigate the ability of the patch pump to detect and direct timing of glucose administration. The secondary endpoint of this study was to investigate the
safety profile of ready-to-use glucagon administered from a pump.

Ready-to-use glucagon bolus through the infusion pump was observed to rapidly raise serum glucagon levels, and the doses employed were not associated
with  increased  insulin  or  C-peptide  concentrations.  Nadir  glucose  and  time  spent  under  75  mg/dL  in  the  period  after  the  glucagon  bolus  were  reduced
progressively with each new stage of protocol development, which involved implementing either earlier hypoglycemia alarms or larger glucagon doses. All
seven patients successfully completed nine treatment visits in this trial. Results showed the treatment to be well-tolerated, with discomfort at the infusion
site and erythema the most frequent adverse events, and no severe adverse events.

Since  this  was  the  first  implementation  of  the  ready-to-use  glucagon  formulation  in  mini-doses  for  PBH,  the  dose  was  chosen  with  caution  to  prevent
rebound hyperglycemia that has been observed with use of rescue doses of glucagon. Using these results, we determined the dose required to effectively
prevent  hypoglycemic  events  in  the  postprandial  setting.  The  results  of  this  trial  were  published  in  the  peer-reviewed  journal  Diabetes  Technology  &
Therapeutics.

XSGO-PB02: Closed-Loop Glucagon Pump for Treatment of Post-Bariatric Hypoglycemia

Following the positive proof-of-concept outcome of XSGO-PB01, in the fourth quarter of 2017, we initiated a randomized, placebo-controlled, double-
blind Phase 2 clinical trial to assess the efficacy of ready-to-use glucagon to prevent and treat hypoglycemia occurring in patients with PBH in response to
meals.  The  primary  objective  of  this  trial  was  to  investigate  the  efficacy  of  a  closed-loop  glucagon  pump  for  PBH  measured  by  real-time  continuous
glucose monitoring ("CGM"). Secondary objectives included safety and tolerability. Following an MMTT, subjects were randomized to either placebo or
glucagon infusion on the first study visit and crossed over to the other treatment during the second treatment visit. Investigators were masked to subject
assignment. In study visits, an MMTT was employed and subjects were treated based on CGM-based measurements of low blood glucose. Subjects were
treated with study drug (ready-to-use glucagon or placebo) at a dose of 300 mcg followed by 150 mcg if needed. Of the 12 subjects that completed the trial,
seven  experienced  severe  hypoglycemia  in  response  to  an  MMTT.  Ready-to-use  glucagon  effectively  treated  hypoglycemia  in  comparison  to  placebo
(p = 0.0082 glucagon vs. placebo). Rescue glucose was needed in 7 of 7 visits for subjects who received placebo and 0 of 7 visits for subjects who received
ready-to-use glucagon. Both drug and placebo were well tolerated with no reported severe adverse events. An abstract of these study results was presented
at the 2019 Endocrine Society annual meeting, and full results were published in the peer-reviewed Journal of Clinical Endocrinology and Metabolism.

This randomized controlled trial data supported the new IND and informed the design of our ongoing Phase 2 clinical trial using a vial/syringe to evaluate
ready-to-use glucagon in PBH.

XSGR-PBH-201:  A  Phase  2,  Interventional,  Randomized,  Double-Blind,  Placebo-Controlled  Pilot  Study  of  Glucagon  RTU  in  Subjects  Who
Experience Hyperinsulinemic Hypoglycemia After Bariatric Surgery

Following our IND clearance in October 2018, we initiated a new Phase 2 clinical trial at five clinical research centers in North America. This study was a
randomized, placebo-controlled, double-blind, two-treatment, two-period, crossover comparison in a Clinical Research Center ("CRC") setting followed by
a randomized, placebo-controlled, double-blind, two arm parallel comparison in the outpatient setting. The purpose of the trial was to evaluate the logistics
of implementing an efficacy and safety study of ready-to-use glucagon ("Glucagon RTU") via vial/syringe to treat symptomatic postprandial hypoglycemia
in subjects with PBH. The study collected safety and efficacy information to help inform a future Phase 3 clinical trial.

During the CRC crossover stage, subjects underwent two high-carbohydrate, solid/liquid-meal tests. After each meal, subjects self-administered blinded
study drug (Glucagon RTU 300 mcg or placebo) when any postprandial autonomic symptom was experienced or when hypoglycemia was confirmed with a
blood glucose measurement of less than 70 mg/dL using a blood glucose meter.

We reported topline results from the completed CRC crossover stage of this trial in December 2019, which demonstrated that most subjects experienced
postprandial hypoglycemia within 90-120 minutes after finishing the meal. Of patients that successfully

17

completed the meal challenge, all subjects were also able to self-administer 300 mcg (a "mini-dose") of the study drug, as directed, during the setting of
declining  blood  glucose.  A  mini-dose  of  Glucagon  RTU  was  adequate  to  restore  or  maintain  normal  blood  glucose  levels  within  15  minutes  of
administration. This effect was maintained at 30 minutes, and hyperglycemia was not observed. The incidence of a follow-on episode of hypoglycemia
(rebound hypoglycemia) requiring oral glucose for rescue was less with Glucagon RTU compared to placebo. After CRC study-related procedures were
completed, subjects were assigned the blinded study drug (Glucagon RTU 300 mcg or placebo) and entered the 12-week outpatient stage. Subjects also
were  trained  to  self-administer  their  assigned  study  treatment,  with  the  presence  of  any  postprandial  autonomic  symptoms.  In  situations  where
hypoglycemia (blood glucose ≤ 70 mg/dl) was present at mini-dosing or continued after treatment, oral glucose tabs were recommended in addition to the
study drug.

In  May  2020,  we  reported  positive  topline  results  from  the  12  subject,  12-week  outpatient  stage  of  the  trial.  More  than  200  postprandial  hypoglycemia
episodes were reported across both treatment arms. Subjects frequently experienced postprandial episodes within 90-120 minutes after finishing meals and
were able to successfully self-administer RTU glucagon during these events. Similar to the in-clinic stage, the sole use of a 300 µg RTU glucagon was
adequate to restore or maintain normal blood glucose levels within 15 minutes of administration and was maintained up to 120 minutes. During episodes
when blood sugar was >70mg/dL at drug dosing, RTU glucagon and placebo were comparable in maintaining blood sugar within normal levels, and RTU
glucagon  did  not  elicit  hyperglycemia.  During  episodes  when  blood  sugar  was  <70  mg/dL  at  drug  dosing  and  without  the  use  of  glucose  tabs,  RTU
glucagon successfully restored blood glucose levels to normal levels (blood sugar ≥70 mg/dL) within 15 minutes, at a higher frequency when compared to
placebo. When failures were observed, subjects in both treatment arms exhibited near-normal counterregulatory responses to hypoglycemia, sufficient to
avoid severe hypoglycemia. Subjects’ use of glucose tablets, both during and after drug dosing as a follow-on rescue, was observed only within the placebo
treatment  arm.  In  this  placebo  arm,  glucose  tablet  use  during  postprandial  hypoglycemia  episodes  resulted  in  rebound  hypoglycemia.  Rebound
hypoglycemia was not observed in the RTU glucagon treatment arm.

In  both  the  CRC  crossover  and  outpatient  stages,  treatment  emergent  adverse  events  with  mini-doses  of  Glucagon  RTU  were  comparable  to  placebo,
including negligible injection site reactions. Mini-doses of Glucagon RTU appear well tolerated, and no serious adverse events occurred.

We are currently finalizing with the FDA expectations for a registration program to support a mini-dose indication for Glucagon RTU in PBH, including
the study design for a Phase 3 clinical trial.

Ready-to-Use Glucagon for Exercise-Induced Hypoglycemia in Diabetes

Exercise-induced  hypoglycemia  and  the  complexity  of  management  aimed  at  its  prevention  represent  major  barriers  to  the  adoption  of  regular  physical
activity  for  many  individuals  with  diabetes  treated  with  insulin.  Although  carbohydrate  ingestion,  including  oral  glucose  tablets,  can  help  ameliorate
hypoglycemia,  patients’  carbohydrate  requirements  can  be  as  high  as  1  gram  per  minute  of  exercise,  which  can  be  counterproductive  to  weight
management. Aerobic exercise, in particular, often results in a significant drop in blood glucose concentrations. Qualitative feedback has shown that the
challenges  in  current  exercise  management  strategies  and  the  need  to  consume  carbohydrates  are  frustrating  and  may  lead  to  minimized  or  complete
omission of exercise for many patients. People with diabetes who are on intensive insulin regimens are at risk of EIH. We believe there is a subset of these
individuals that exercises at least three times per week per current guidelines who could potentially use a mini-dose of ready-to-use glucagon each time
they exercise. If approved, our ready-to-use glucagon would represent a significant market opportunity in the treatment for EIH.

Xeris Offering—Mini-doses of Ready-to-Use Glucagon for Treatment of EIH

We  are  developing  a  mini-dose  of  our  ready-to-use,  liquid-stable  glucagon  and  have  observed  appropriate  dose-dependent  PK  and  PD  responses  when
administered subcutaneously at doses of 75, 150 and 300 µg in adults with T1D. A proof-of-concept study further demonstrated that a mini-dose of 150 µg
of glucagon prevented non-severe hypoglycemia to a substantially similar degree as oral glucose tablets that are commonly used during exercise to prevent
or correct non-severe hypoglycemia in adults with T1D. As such, the use of mini-dose glucagon enabled patients to avoid the unnecessary caloric intake
inherent in glucose tablets or other types of carbohydrates.

There currently are no FDA-approved glucagon products which enable individuals to modestly increase glucagon levels at the start of exercise. Glucagon
rescue kits exist as a lyophilized powder that must be reconstituted in diluent immediately prior to injection as they are unstable in aqueous solutions for
extended periods of time. Despite the challenging reconstitution process, there has been significant documented off-label use, in which patients with T1D
mini-dose glucagon using the traditional glucagon kits. Currently Gvoke and glucagon rescue kits are only indicated at an emergency dose of 1 mg for
rescue from severe hypoglycemia. In addition, Eli Lilly’s Baqsimi is a one-time use intranasal powder, the administration of which delivers a full 3 mg
rescue dose of glucagon.

We  have  been  awarded  $2.1  million  in  grants  from  organizations  such  as  the  Leona  M.  and  Harry  B.  Helmsley  Charitable  Trust  and  the  NIH  National
Institute of Diabetes and Digestive and Kidney Diseases, and we have worked with institutions including the Joslin Diabetes Center and the University of
Pennsylvania for clinical development of our mini-dose glucagon product candidates.

Clinical Experience

We have successfully completed a number of preclinical studies in multiple species to support the safety of mini-dose glucagon, as well as Phase 2 safety
and efficacy clinical trials in subjects with T1D.

Phase 2 Clinical Trials

XSMP-203: The Use of Mini-Dose Glucagon to Prevent Exercise-Induced Hypoglycemia in Type 1 Diabetes

Based on previous dose-finding trials (XSMP-201 and XSMP-202), we collaborated on a third Phase 2 clinical trial of mini-dose glucagon for EIH in the
first quarter of 2016. The primary analysis of this trial was comparison of the glycemic response of 150 µg mini-dose glucagon against current standards of
care, including basal insulin reduction and glucose tablet consumption, to mitigate EIH. In particular, this was a four-session, randomized crossover trial
involving 15 adults with T1D who exercised at 50-55% VO2max for 45 minutes under conditions of no intervention (control), 50% basal insulin reduction,
40  g  oral  glucose  tablets,  or  150  µg  subcutaneous  mini-dose  glucagon,  all  administered  five  minutes  before  exercise.  Secondary  endpoints  were  to
investigate the safety profile of this product candidate.

During the exercise sessions conducted in this study, plasma glucose increased slightly with mini-dose glucagon compared to a decrease with control and
insulin reduction, as depicted in the figure below. Plasma glucose increased more greatly with glucose tablets. Hypoglycemia (<70 mg/dL) was experienced
by  six  subjects  during  control,  five  during  insulin  reduction  and  none  with  glucose  tablets  or  mini-dose  glucagon;  however,  five  subjects  experienced
hyperglycemia (>250 mg/dL) with glucose tablets and one with mini-dose glucagon. The study was well-controlled, as insulin levels were not different
among sessions, while glucagon levels increased only in the mini-dose glucagon arm, as expected.

In a Phase 2 randomized, controlled clinical study, T1D subjects (n=16) administered mini-dose glucagon completed a 45-minute exercise session
without adjusting basal insulin or ingesting glucose tabs (calories).

The Phase 2 study concluded that mini-dose glucagon (150 µg) may have the potential to prevent EIH in adults with T1D. In addition, mini-dose glucagon
may  be  more  effective  at  preventing  EIH  than  insulin  reduction  which  was  associated  with  a  similar  rate  and  magnitude  of  hypoglycemia  as  no
intervention.  Moreover,  while  mini-dose  glucagon  was  as  effective  as  glucose  tablets  for  preventing  EIH,  mini-dose  glucagon  may  result  in  less  post-
intervention hyperglycemia than ingestion of carbohydrates and avoids the consumption of unnecessary calories. The results of this study were published in
the journal Diabetes Care.

XSMP-204:  A  Phase  2  Randomized,  Placebo-Controlled,  Double-Blind,  Parallel  Study  to  Evaluate  Glucagon  RTU  (Glucagon  Injection)
Compared to Standard of Care for the Prevention of Exercise-Induced Hypoglycemia During Regular Aerobic Exercise in Adults with Type 1
Diabetes

This trial was a randomized, placebo-controlled, double-blind, two-treatment, two-period, crossover comparison in a clinical research center (CRC) setting,
followed  by  a  randomized,  placebo-controlled,  double-blind  two-arm  comparison  with  a  third  open-label  arm  in  an  outpatient  setting  to  evaluate  the
preliminary efficacy and safety of RTU glucagon to prevent EIH in adults with T1D who perform regular, moderate-to-high intensity aerobic exercise. T1D
subjects who receive daily insulin treatment via a subcutaneous infusion

19

pump performed at least 45 minutes duration of exercise in a CRC setting and at least 30 minutes duration of moderate-to-high intensity exercise in the
outpatient setting and were monitored for hypoglycemia in the exercise recovery period. In January 2020, we reported positive results from the CRC setting
of  this  Phase  2  study.  Results  from  this  stage  of  the  Phase  2  study  showed  that  a  mini-dose  of  RTU  glucagon  was  adequate  to  maintain  normal  blood
glucose levels during prolonged, moderate-to-high intensity aerobic exercise.

For persons with diabetes, standard of care for aerobic exercise includes 50% insulin pump reduction. In the outpatient stage, the trial was examining if the
subcutaneous administration of RTU glucagon just before exercise, with or without a 50% reduction in basal rate insulin, compared to a 50% basal rate
insulin  reduction  alone  prevents  the  occurrence  of  hypoglycemia  (i.e.,  blood  glucose  <70  mg/dL)  measured  by  blood  glucose  meter  during  and  after
moderate-to-high intensity aerobic exercise by adult subjects with T1D in an outpatient setting. Subjects were randomly assigned to RTU Glucagon with
50% insulin pump reduction (RTU Glucagon + standard of care); placebo injection with 50% insulin pump reduction (standard of care); or RTU Glucagon
without insulin pump reduction (Open Label RTU Glucagon). In June 2020, we reported positive results from the outpatient stage of this Phase 2 study.
Results  from  this  stage  of  the  Phase  2  study  showed  that  a  mini-dose  of  RTU  glucagon  was  adequate  to  maintain  normal  blood  glucose  levels  during
prolonged, moderate-to-high intensity aerobic exercise in a real-world setting with or without adjustment to insulin.

During the 12-week outpatient stage, 45 subjects completed 795 aerobic exercise sessions. Over this time when individually compared to standard of care
alone, the number of EIH episodes was significantly less with RTU Glucagon + standard of care and with Open Label RTU Glucagon. RTU Glucagon +
standard of care resulted in an approximately 70% lower rate of EIH when compared to standard of care alone. Additionally, Open Label RTU Glucagon
resulted in an approximately 54% lower rate of EIH when compared to standard of care alone. The difference in the incidence rates of EIH between the two
RTU Glucagon arms was not statistically significant.

Across all outpatient stage exercise sessions, the nominal use of oral glucose tablets during and after exercise, in order to treat hypoglycemia, was greater in
the  standard  of  care  arm  compared  to  RTU  Glucagon  +  standard  of  care  and  Open  Label  RTU  Glucagon.  Consequently,  the  nominal  incidence  of
hyperglycemia episodes (blood glucose > 180 mg/dl) was observed to be 2.4 fold greater in the standard of care arm when compared to RTU Glucagon +
standard of care arm. RTU Glucagon did not appear to individually contribute to hyperglycemia. When hyperglycemia events did occur, the time duration
and severity of events did not differ between treatment arms.

In both phases of the study, mini doses of RTU glucagon were safe and well tolerated, and no serious adverse events occurred.

We are currently finalizing with the FDA expectations for a registration program to support a mini-dose indication for Glucagon RTU in EIH, including the
study design for a Phase 3 clinical trial.

Ready-to-Use Glucagon for Gastroenterology

We are currently in Phase 1 development with product candidate XP-9164, an early-stage compound for gastroenterology.

Ready-to-Use Glucagon for Congenital Hyperinsulinism

We  have  decided  not  to  proceed  with  a  planned  Phase  3  CHI  study  based  on  the  challenging  regulatory  pathway  coupled  with  the  limited  market
opportunity. Instead, we will consider requests to make our liquid-stable glucagon available for approved Expanded Access requests at no cost to eligible
patients.  (Expanded  Access  is  a  potential  pathway  for  a  patient  with  an  immediately  life-threatening  condition  or  serious  disease  to  gain  access  to  an
investigational drug for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available.)

Non-Glucagon Programs

XeriSol Pramlintide-Insulin Co-formulation

Leveraging  our  XeriSol  platform,  we  are  developing  a  ready-to-use  fixed  dose  combination  of  insulin  and  pramlintide  to  be  delivered  via  a  vial  and
syringe. Pramlintide is an injectable amylin analog for both Type 1 and 2 diabetes. In normal physiology, amylin is a hormone that is co-secreted into the
bloodstream  at  a  fixed  ratio  with  insulin  by  the  beta  cells  of  the  pancreas.  The  U.S.  approval  and  launch  of  pramlintide  (Symlin®)  brought  significant
interest because of its ability, when used in combination with mealtime insulin, to flatten post-prandial blood glucose levels, reduce glucose excursions, and
cause  weight  loss.  Short-term  and  long-term  clinical  trials  have  found  that  adding  pre-prandial  pramlintide  injections  to  insulin  therapy  reduced  post-
prandial glucose excursions and improved overall glycemic control (hemoglobin A1c levels) in patients with T1D. Clinically, pramlintide accomplishes this
by reducing food intake, delaying gastric emptying, and reducing endogenous glucose production in the liver by suppressing glucagon secretion. The use of
pramlintide also allows for approximately 30% less insulin utilization due to differential efficacy.

20

Pramlintide is indicated in people with diabetes for use at all major meals where patients already administer bolus insulin. The addition of a pramlintide
regimen  adds  three  or  more  separate  injections  daily  which  could  be  a  challenging  proposition  in  this  patient  population.  We  believe  current  use  of
pramlintide  is  quite  limited  because  the  injection  burden  issues  outweigh  the  perceived  benefits.  To  date,  co-formulation/mixtures  of  pramlintide  and
insulin have experienced technical difficulties due to the physico-chemical incompatibility of a native mixture of each of these components. We believe our
ready-to-use,  room-temperature  stable  XeriSol  co-formulation  of  pramlintide  and  regular  insulin  as  well  as  pramlintide  and  lispro  insulin  can  benefit
patients  by  reducing  the  number  of  required  injections.  We  address  the  co-formulation  problem  by  utilizing  our  XeriSol  technology  to  develop  stable
pramlintide  and  regular  insulin  formulations  as  well  as  stable  pramlintide  and  lispro  insulin  formulations.  XeriSol  forms  a  stable  co-formulation  of
pramlintide and insulins (regular or lispro) without the need for novel excipients. XeriSol pramlintide-insulins can be presented as a variable-fixed-ratio
combination of either six or nine µg pramlintide per unit of insulin. These ratios have been shown to have beneficial clinical efficacy profiles in previous
studies.

XeriSol pramlintide-insulin has several potentially valuable stability properties from a patient use perspective, namely potential two-year stability when
refrigerated and up to 90 days at room temperature. This stability profile is comparable to current insulin products and would not introduce new handling
challenges for existing insulin patients.

In preclinical studies, we characterized the PK and PD of pramlintide and various insulin formulations in normal and streptozotocin induced diabetic rats
(mimicking T1D) given as separate injections or as a XeriSol pramlintide-insulin combined dose. Consistent with pramlintide’s known pharmacological
action,  there  was  no  glucose  lowering  with  pramlintide  alone.  Profiles  for  pramlintide  were  similar  to  either  saline  or  XeriSol  vehicle  administered  by
subcutaneous  injection  in  rats.  XeriSol  pramlintide-insulin  demonstrated  a  longer  duration  of  glucose  lowering  compared  to  separate  injections  of
pramlintide (Symlin) and insulin (Humulin ). Figures 1 and 2 below show a comparison of efficacy based on changes in glucose levels after injection of
XeriSol  pramlintide-insulin  and  pramlintide-lispro  in  comparison  with  separate  injections  of  Symlin  and  Humulin  or  Symlin  and  Humalog  in a rodent
model.  In  a  preclinical  study,  XeriSol  pram-insulin  maintained  glucose  control  for  approximately  four  hours  as  compared  to  separate  injections  of
commercially available product combinations (mimicking human subcutaneous administration) that begin to lose glucose control after approximately two
hours.

Figure 2 Glucose Levels after Injection of XeriSol Pramlintide-Lispro and Humalog/Symlin Co-Injection

We  initiated  a  study  of  our  novel  XeriSol  pramlintide-insulin  co-formulation  in  a  Phase  2  clinical  trial  in  T1D  in  the  third  quarter  of  2019.  This  study
compares XeriSol pramlintide-insulin versus separate injections of Symlin and Humulin in diabetic subjects. According to recent guidance from the FDA,
the insulin component of our XeriSol pramlintide-insulin co-formulation is subject to the FDA’s “deemed to be a license” provision of the Biologics Price
Competition  and  Innovation  Act  of  2009,  which  may  necessitate  that  we  submit  a  Biologics  License  Application  ("BLA")  for  any  future  marketing
authorization by the FDA.

XP-3924: A Phase 2, Randomized, Open-Label, Crossover, PD/PK Study of a Novel Pram-Insulin Co-Formulation in Adults With T1D

In June 2020, we announced positive results from our proof-of-concept Phase 2 study of our novel XeriSol pramlintide-insulin co-formulation in adults
with  T1D.  The  completed  Phase  2  study  was  a  randomized,  open-label,  active  comparator-controlled,  three-period  cross-over  study,  which  enrolled  18
adult participants with T1D. This study aimed to investigate the PK and PD of pramlintide, and the safety and tolerability of a single dose of XP-3924
(administered  based  upon  the  subjects’  insulin:carbohydrate  ratio),  when  compared  to  co-administration  of  regular  insulin  (Humulin)  and  pramlintide
(Symlin) and to an injection of regular insulin alone (Humulin). Subjects were randomly allocated to a sequence of three treatments: XP-3924 (with 50%
insulin reduction), regular insulin, or regular insulin (with 50% insulin reduction) plus pramlintide co-administered as separate injections. The study drugs
were administered SC before the intake of a standardized 75-gram oral glucose challenge. The subjects’ blood glucose levels were monitored for six hours
after drug dosing. Treatment with XP-3924 resulted in a 62.3% reduction of hyperglycemia (blood glucose >180 mg/dL) after the glucose challenge when
compared to Humulin (p<0.001). Additionally, XP-3924 exhibited comparable postprandial glycemic control to that of the co-administered injections of
Humulin and Symlin. The mean absolute change in blood glucose was less in XP-3924 when compared to both Humulin and co-administered injections of
Humulin  and  Symlin  after  the  oral  glucose  challenge.  The  glucose  variability  after  treatment  with  XP-3924  was  less  than  both  Humulin  and  co-
administered injections of Humulin and Symlin, as defined by the comparison of the coefficient of variation of all plasma glucose readings across the six-
hour duration of study treatments. The incidence and severity of treatment emergent adverse events was comparable across all treatment arms, as were the
overall number of hypoglycemic events during dosing visits. There were minimal gastrointestinal side effects reported in any treatment arm. There was a
comparable incidence of injection site reactions, and no edema was noted across all treatment arms. XP-3924 was safe and well tolerated, and no serious
adverse events occurred in this study.

We are currently finalizing with the FDA expectations for a registration program to support a BLA, including the study design for a Phase 3 clinical trial
program.

Ready-to-Use Diazepam

Leveraging our XeriSol formulation technology, we are developing a ready-to-use diazepam formulation for which we were granted an orphan designation
by the FDA for the treatment of ARS and Dravet syndrome in patients with epilepsy. Approximately 160,000 people in the United States experience ARS.
Dravet syndrome is a rare form of intractable epilepsy that begins in infancy with an estimated incidence rate of 1:16,000 to 1:21,000 in the United States.

22

Immediate treatment of epileptic seizures is critical to avoid increased risks of morbidity and mortality, including permanent neuronal damage, behavioral
abnormalities and an increased probability in the need for life-long care.

Injectable and rectal gel formulations of diazepam are the current standard of care for the emergency treatment of epileptic seizures. In 2018, diazepam
formulations generated total U.S. sales of approximately $86 million, of which Diastat® Rectal Gel and its generic formulations comprised $74 million.
Diastat requires a multi-step procedure which makes it more difficult to administer while a patient is experiencing seizures. Additionally, the use of rectal
gel in both middle school children and young adults with ARS is reduced because of social stigma. These characteristics are limitations that may diminish
the specific demand for rectal diazepam products. Due to this limitation, we believe the market for diazepam in ARS is underpenetrated. We believe that a
ready-to-use diazepam injectable rescue pen would improve patient quality of life and drive adoption of diazepam to treat ARS.

Our ready-to-use diazepam formulation has demonstrated rapid onset and high bioavailability in preclinical models. We were awarded grants totaling $2.3
million from the Epilepsy Foundation and the NIH for this program. An IND application for our ready-to-use diazepam injectable rescue pen for ARS went
into effect on November 28, 2018. This IND authorized us to initiate a study (XSDZ-101) evaluating the PK and PD of our ready-to-use, room-temperature
stable liquid diazepam formulation in normal volunteers. Below is a description of this study.

XSDZ-101:  A  Randomized  Crossover  Study  of  the  Comparative  Bioavailability,  Pharmacokinetics,  and  Tolerability  of  Diazepam  After
Subcutaneous, Intramuscular, and Rectal Administration in Healthy Subjects

In  May  2019,  we  announced  positive  results  from  our  Phase  1  study  of  our  novel  formulation  of  diazepam.  The  open-label,  three-treatment,  three-way
crossover,  randomized  controlled  study  was  conducted  among  24  healthy  volunteers  to  assess  the  bioavailability  and  PK  of  our  novel  formulation  of
diazepam  (XP-0863)  after  IM  and  SC  administration  compared  to  an  administration  of  commercial  diazepam  rectal  gel  (Diastat).  Secondary  objectives
were to assess the safety and tolerability of our diazepam after SC and IM administration. Our IM and SC administration of 10 mg diazepam yielded higher
exposure as compared to an equivalent dose of diazepam rectal gel as assessed by AUC "(zero to infinity)". In individual comparisons, our administration
resembled Diastat for both Cmax and Tmax. Additionally, both arms were safe and well-tolerated as a single dose. The study found no safety trends in any
treatment group.

Based  on  these  results,  in  the  second  half  of  2019  we  initiated  a  Phase  1b  weight-based  dosing  study  with  IM  administration  of  diazepam  in  healthy
volunteers  to  assess  the  pharmacokinetics,  safety  and  tolerability  of  two  different  weight-based  doses  of  IM  XP-0863  diazepam  when  compared  to  a
weight-based dose of Diastat rectal gel. In April 2020, we reported positive topline results, and in July 2020 we reported complete results from this Phase
1b study.

XP-0863 is a highly concentrated liquid diazepam for IM injection that is intended for the treatment of seizure emergencies in patients ≥ 2 years of age,
with partial onset or generalized convulsive seizures, who are identified jointly by their caregivers and physicians as suffering intermittent and periodic
episodes  of  markedly  increased  seizure  activity.  XP-0863  uses  the  XeriSol  technology  platform  to  overcome  the  solubility  problems  associated  with
diazepam,  reduces  injection  burden,  provides  comparable  pharmacokinetics  to  diazepam  rectal  gel  (Diastat),  and  may  support  the  prompt  and  full-dose
drug delivery of diazepam during seizure emergencies.

The  Phase  1b  study  was  an  open-label,  weight-based  dose,  three-treatment,  three-way  crossover  study  in  healthy  adult  subjects.  This  study  aimed  to
investigate the pharmacokinetics, safety, and tolerability of two different weight-based doses of intramuscular XP-0863 when compared to a weight-based
dose of Diastat rectal gel. Subjects were randomly allocated to a sequence of three treatments: XP-0863 IM (0.25 mg/kg), XP-0863 IM (0.125 mg/kg), or
Diastat (0.2 mg/kg). The subjects’ diazepam blood levels were monitored over 21 days after drug dosing. XP-0863 showed comparable pharmacokinetics
to Diastat, with similar partial AUCs of XP-0863 (0.25 mg/kg) to Diastat early after dosing and with increased overall exposure (zero to infinity) when
compared to Diastat. XP-0863 (0.25 mg/kg) had comparable Cmax when compared to Diastat. The weight-based doses of XP-0863 were safe and well
tolerated, with minimal sedation and injection site reactions, and no serious adverse events occurred.

In October 2020, we were granted Fast Track designation by the FDA for our novel formulation of diazepam, which could advance directly into a Phase 3
registration study in both pediatric and adult patients with epilepsy.

Ready-to-Use Product for Endocrinology

We are currently in Phase 1 development with product candidate XP-8121, an early-stage program for endocrinology.

Manufacturing and Supply

We currently contract with third parties for the manufacture, assembly, testing, packaging, storage and distribution of our products. In our experience, third
party contract manufacturing organizations ("CMOs") are generally cost-efficient, high quality and reliable, and we currently have no plans to build our
own  manufacturing  or  distribution  infrastructure.  Our  technical  team  has  extensive  pharmaceutical  development,  manufacturing,  analytical,  quality  and
distribution experience and is qualified and capable of managing supply chain operations across multiple CMOs. Our Quality System, Standard Operating
Procedures and CMO interfaces are designed to promote cGMP compliance and effective regulatory communications. We selected our CMOs for specific
competencies, and they have met our development, manufacturing, quality and regulatory requirements and have all been involved in manufacturing our
clinical supplies, commercial registration batches, and commercial product.

Glucagon  is  the  active  pharmaceutical  ingredient  ("API")  used  in  Gvoke  and  our  ready-to-use  glucagon  product  candidates.  Bachem  Americas,  Inc.,
("Bachem") is our primary commercial source for API. Bachem holds a U.S. drug master file for glucagon produced at its facility in Switzerland, and its
manufacturing  process  is  fully  validated.  We  have  entered  into  a  non-exclusive  supply  agreement  with  Bachem.  While  we  believe  that  Bachem  has
sufficient capacity to satisfy our long-term requirements for Gvoke and other pipeline products utilizing ready-to-use glucagon, we are evaluating alternate
sourcing options.

Manufacturing drug product for Gvoke requires an aseptic fill/finish facility capable of handling solvents and a cyclic olefinic polymer syringe. Pyramid
Laboratories, Inc. ("Pyramid") has been actively involved in the development of Gvoke and our ready-to-use glucagon product candidates. Its facility in
California is our primary source for drug product. We have entered into a non-exclusive supply agreement with Pyramid. While we believe that Pyramid
has sufficient capacity to satisfy our demand requirements for at least three to five years, we are evaluating alternate sourcing options.

The auto-injector used to deliver drug product in Gvoke HypoPen is a proprietary multi-product device platform developed by SHL Medical AG, SHL
Pharma  LLC,  and  SHL  Pharma  (collectively  "SHL").  SHL  produces  device  sub-assemblies  in  their  facilities  in  Taiwan  and  performs  final  drug
product/device assembly operations at its facility in Florida. We have entered into a non-exclusive supply agreement with SHL. We intend to source the
device from a single supplier over the life of the product.

We believe that a number of CMOs can provide suitable secondary packaging services for Gvoke, and we have entered into commercial supply agreements
with  one  vendor.  A  number  of  third-party  logistic  providers  can  provide  commercial  order  processing  and  finished  goods  distribution  services  to  U.S.
wholesale customers, and we have a commercial distribution agreement with one such vendor.

To date, we and our suppliers and third-party manufacturing partners have been able to continue to supply our products to our patients and currently do not
anticipate any interruptions in supply. Our third-party contract manufacturing partners continue to operate at or near normal levels, with enhanced safety
measures  intended  to  prevent  the  spread  of  the  coronavirus.  While  we  currently  do  not  anticipate  any  interruptions  in  our  manufacturing  process,  it  is
possible  that  the  COVID-19  pandemic  and  response  efforts  may  have  an  impact  in  the  future  on  our  third-party  suppliers  and  contract  manufacturing
partners’ ability to supply and/or manufacture our products.

Competition

Our industry is characterized by intense competition and a strong emphasis on proprietary products. We believe the key competitive factors that will affect
the  development  and  commercial  success  of  our  products  and  product  candidates  include  likelihood  of  successful  dose  delivery,  ease  of  administration,
therapeutic efficacy, safety and tolerability profiles and cost. While we believe that our product and product candidate platform, development expertise and
scientific knowledge provide us with competitive advantages, we face potential competition from many different sources, including major pharmaceutical,
specialty  pharmaceutical  and  biotechnology  companies.  Many  of  our  potential  competitors  have  substantially  greater  financial,  technical  and  human
resources than we do, as well as more experience in the development of product candidates, obtaining FDA and other regulatory approvals of products, and
the commercialization of those products.

Four emergency glucagon kits are currently available to treat severe hypoglycemia: Eli Lilly’s GEK, Novo Nordisk’s GlucaGen HypoKit, Fresenius Kabi's
Glucagon Emergency Kit and Amphastar's generic Glucagon for Injection Emergency Kit, the ANDA for which was approved by the FDA on December
29, 2020 for the treatment of severe hypoglycemia. Each kit is sold as a vial of lyophilized, glucagon powder with an exposed syringe/needle that contains
a liquid diluent. The glucagon powder must be combined with the liquid diluent at the time of use and drawn into a syringe in accordance with a complex
multi-step  reconstitution  and  dose  calibration  procedure.  Additionally,  once  reconstituted,  the  glucagon  must  be  used  immediately  because  once  the
lyophilized  glucagon  is  combined  with  water,  the  solution  becomes  unstable  and  can  fibrillate,  rendering  it  potentially  inactive.  We  believe  that  the
drawbacks of traditional kits and the lack of conversations regarding glucagon limit their adoption. Innovative glucagon products, including our Gvoke and
Eli Lilly's intranasal glucagon dry powder, Baqsimi, were both approved by the FDA and launched in 2019.

24

In our market research, respondents ranked the importance of successful full-dose delivery and ability to tell if the full dose was administered significantly
higher than the attribute "needleless". Caregivers and people with diabetes associated Gvoke HypoPen with efficacious and successful dose delivery, as
well as ease of ability to tell if the full dose was administered. Similarly, healthcare professionals indicated that one of the most appealing attributes of
Gvoke is the greater likelihood of successful dose delivery.

Zealand Pharma is developing dasiglucagon, a stable analog of human glucagon, in an auto-injector for subcutaneous administration. Zealand's New Drug
Application ("NDA") for their dasiglucagon HypoPal® Rescue Pen for the treatment of hypoglycemia in people with diabetes is under review by the FDA
with a PDUFA date of March 27, 2021.

While there are currently no FDA-approved products indicated for treatment of PBH, we are aware of a number of product candidates in development.
Eiger Biopharmaceuticals is developing its product candidate avexitide (exendin 9-39), a glucagon-like peptide-1 receptor antagonist, to be administered
subcutaneously once or twice daily. Eiger completed a Phase 2 clinical study with avexitide and an end-of-Phase 2 FDA meeting and received guidance
from  the  FDA  on  Phase  3  clinical  requirements.  Additionally,  Zealand  Pharma  has  announced  positive  topline  results  from  its  Phase  2  trial  with
dasiglucagon in patients with PBH.

Currently, the first-line emergency treatment of epileptic seizures in the outpatient setting is the administration of diazepam rectal gel marketed as Diastat
by Valeant Pharmaceuticals. UCB’s midazolam nasal spray Nayzilam, indicated for seizure clusters and ARS, launched in December 2019, and Neurelis,
Inc. received approval in January 2020 for their nasal diazepam product, VALTOCO™ (previously known as NRL-1), for the treatment of seizure clusters
and  ARS.  VALTOCO  became  commercially  available  in  March  2020.  The  FDA  issued  a  Complete  Response  Letter  for  Aquestive’s  NDA  for  buccal
soluble diazepam Libervant™ (previously known as AQST-203), also for the treatment of seizure clusters and ARS. Aquestive has reported that they will
continue  to  have  follow-up  meetings  with  the  FDA  to  discuss  a  path  to  approval.  In  June  2020,  UCB  Inc.  acquired  the  worldwide  rights  to  Staccato®
Alprazolam  from  Engage  Therapeutics,  who  was  developing  an  inhaled  alprazolam  (known  as  STAP-001)  for  ARS.  UCB  Inc.  will  continue  the
development of this product, which is currently in Phase 2 development.

Intellectual Property

Proprietary Protection

Our  commercial  success  depends  in  part  on  our  ability  to  obtain  and  maintain  proprietary  protection  for  our  products  and  product  candidates,
manufacturing  and  process  discoveries  and  other  know-how,  to  operate  without  infringing  the  proprietary  rights  of  others,  and  to  prevent  others  from
infringing  our  proprietary  rights.  We  have  been  building  and  continue  to  build  our  intellectual  property  portfolio  relating  to  our  product  candidates  and
technology. Our policy is to seek to protect our proprietary position by, among other methods, filing U.S. and certain foreign patent applications related to
our proprietary technology, inventions and improvements that are important to the development and implementation of our business. We also intend to rely
on trade secrets, know-how, continuing technological innovation and potential in-licensing opportunities to develop and maintain our proprietary position.
We cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in
the future, nor can we be sure that any of our existing patents or any patents that may be granted to us or our partners in the future will be commercially
useful in protecting our technology.

Patent Rights

As of December 31, 2020, we owned 117 issued patents globally, of which 14 are issued U.S. patents. As of December 31, 2020, three of our U.S. issued
patents have pending continuations or divisionals in process which may provide additional intellectual property protection if issued as U.S. patents. Our
issued patents expire between December 22, 2023 and April 22, 2036, subject to payment of required maintenance fees, annuities and other charges. The
subset of our patent estate directed specifically to our ready-to-use glucagon consists of one U.S. composition of matter patent that is scheduled to expire in
year 2036, two pending U.S. patent applications and 18 pending international patent applications. Patents that issue based on these applications would also
expire in year 2036.

Trade Secrets and Other Protection

In addition to patented intellectual property, we also rely on trade secrets and proprietary know-how to protect our technology and maintain our competitive
position,  especially  when  we  do  not  believe  that  patent  protection  is  appropriate  or  can  be  obtained.  Our  policy  is  to  require  each  of  our  employees,
consultants  and  advisors  to  execute  a  confidentiality  and  inventions  assignment  agreement  before  beginning  their  employment,  consulting  or  advisory
relationship  with  us.  The  agreements  generally  provide  that  the  individual  must  keep  confidential  and  not  disclose  to  other  parties  any  confidential
information  developed  or  learned  by  the  individual  during  the  course  of  the  individual’s  relationship  with  us  except  in  limited  circumstances.  These
agreements generally also provide that we own

25

all inventions conceived and/or reduced to practice by the individual in the course of their employment with us or rendering services to us.

Other Intellectual Property Rights

We file trademark applications and pursue registrations in the United States and abroad when appropriate. We own U.S. registered trademarks for the marks
Xeris  Pharmaceuticals,  GVOKE,  GVOKE  HYPOPEN  and  HYPOPEN,  and  the  registered  trademark  for  OGLUO  in  the  EU.  We  also  own  pending
trademark applications for XERISOL, XERIJECT and GVOKE HYPOPEN 2-PACK in the U.S.; for XERISOL and XERIJECT in the EU; and pending
trademark applications and/or registered trademarks for GVOKE and GVOKE HYPOPEN in other ex-U.S. countries, all for use in connection with our
pharmaceutical research and development and products, as well as trade names that could be used with our product candidates.

From time to time, we may find it necessary or prudent to obtain licenses from third-party intellectual property holders.

Grant Agreements

Through  December  31,  2020,  we  have  received  $1.9  million  in  grant  proceeds  for  the  development  of  a  stable  liquid  glucagon  for  use  in  an  artificial
pancreas.  Under  the  terms  of  one  of  the  grant  agreements,  we  will  be  required  to  pay  up  to  four  times  the  $0.9  million  award  received  upon
commercialization  of  glucagon  for  use  in  the  artificial  pancreas.  If  we  undergo  a  change  in  control,  then  we  will  be  required  to  pay  a  mid-single  digit
percentage of the gross proceeds, capped at four times the award amount less any amounts already paid. Additionally, if sales of glucagon for use in the
artificial pancreas exceed $750 million in the first five years after the first commercial sale, then we would be required to make an additional payment equal
to the original award amount.

Through December 31, 2020, we received $2.0 million in grant proceeds to help fund our EIH program. Under terms of one of the agreements, we will be
required  to  pay  up  to  two  times  the  $0.9  million  award  amount  upon  the  commercialization  of  an  EIH  product.  These  amounts  are  a  low  double-digit
percentage of annual gross sales of an EIH product, capped at $0.5 million annually. If we undergo a change in control, then we will pay a mid-single digit
percentage of the consideration capped at two times the award amount less any amounts already paid. Additionally, if sales exceed $1 billion, we will be
required to pay an additional amount equal to two times the award amount.

Through December 31, 2020, we received $1.0 million in grant proceeds to help fund our T1D chronic glucagon programs. Under terms of this agreement,
we  will  be  required  to  pay  up  to  two  times  the  award  amount  upon  the  commercialization  of  any  chronic  glucagon  program.  These  amounts  are  a  low
double-digit percentage of annual gross sales of all T1D chronic glucagon programs, capped at $0.5 million annually. If we undergo a change in control,
then we will pay a mid-single digit percentage of the consideration capped at two times the award amount less any amounts already paid. Additionally, for
each chronic glucagon program where sales exceed $500 million, we will be required to pay an additional amount equal to two times the award amount.

We  also  have  received  awards  from  the  NIH  National  Institute  of  Diabetes  and  Kidney  Diseases,  which  awards  are  not  subject  to  any  repayment
obligations.

Long-Term Debt

In June 2020, the Company completed a public offering of $86.3 million aggregate principal amount of the Company's 5.00% Convertible Senior Notes
due 2025 (the "Convertible Notes"), including $11.3 million pursuant to the underwriters' option to purchase additional notes which was exercised in full in
July 2020. A total principal amount of $39.1 million of Convertible Notes converted into equity in the second half of 2020. As of December 31, 2020, the
outstanding balance of Convertible Notes was $47.2 million.
In addition, as of December 31, 2020, we have $43.5 million outstanding under our Amended and Restated Loan and Security Agreement with Oxford
Finance LLC, as the collateral agent and a lender, and Silicon Valley Bank, as a lender.

Government Regulation

United States Drug and Biological Product Development

In the United States, the FDA regulates drugs, medical devices and combinations of drugs and devices, or combination products, under the FDCA and its
implementing  regulations  and  biologics  under  the  FDCA  and  the  Public  Health  Service  Act  ("PHSA")  and  their  implementing  regulations.  Drugs,
biologics, medical devices and combination products are also subject to other federal, state and local statutes and regulations. The process of obtaining
regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of
substantial  time  and  financial  resources.  Failure  to  comply  with  the  applicable  U.S.  requirements  at  any  time  during  the  product  development  process,
approval process or after approval may subject an applicant to administrative or judicial sanctions. These sanctions could include, among other actions, the
FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, untitled or warning letters, requests for voluntary product recalls
or  withdrawals  from  the  market,  product  seizures,  total  or  partial  suspension  of  production  or  distribution,  injunctions,  fines,  refusals  of  government
contracts, restitution, disgorgement, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.

Our products and certain of our product candidates are subject to regulation as combination products, which means that they are composed of both a drug
product and device product. If marketed individually, each component would be subject to different regulatory pathways and reviewed by different Centers
within the FDA. A combination product, however, is assigned to a Center that will have primary jurisdiction over its regulation based on a determination of
the combination product’s primary mode of action, which is the single mode of action that provides the most important therapeutic action. In the case of
Gvoke and some of our product candidates, the primary mode of action is attributable to the drug component of the product, or biological component of the
product,  which  means  that  the  FDA’s  Center  for  Drug  Evaluation  and  Research  has  primary  jurisdiction  over  the  premarket  development,  review  and
approval. Accordingly, we plan to continue to investigate our products through the IND framework and seek approval through the NDA or BLA pathway.
Based on our discussions with the FDA to date, we do not anticipate that the FDA will require a separate medical device authorization for the device, but
this could change during the course of its review of any marketing application that we may submit. The process required by the FDA before a drug or
biologic may be marketed in the United States generally involves the following:

<

<

<

<

<

<

<

<

<

<

<

completion  of  extensive  preclinical  laboratory  tests,  animal  studies  and  formulation  studies  in  accordance  with
applicable regulations, including the FDA’s Good Laboratory Practice ("GLP") regulations;
submission to the FDA of an IND, which must become effective before human clinical trials may begin;
approval by an independent institutional review board ("IRB"), representing each clinical site before each clinical trial
may be initiated;
performance  of  adequate  and  well-controlled  human  clinical  trials  in  accordance  with  an  applicable  IND  and  other
clinical study related regulations, sometimes referred to as good clinical practices ("GCPs"), to establish the safety and
efficacy of the proposed drug or biologic for its proposed indication;
submission to the FDA of an NDA or BLA;
satisfactory  completion  of  an  FDA  pre-approval  inspection  of  the  manufacturing  facility  or  facilities  at  which  the
product,  or  components  thereof,  are  produced  to  assess  compliance  with  the  FDA’s  current  good  manufacturing
practice requirements ("cGMP");
potential FDA audit of the clinical trial sites that generated the data in support of the NDA or BLA;
payment of associated user fees;
review by an FDA advisory committee, where appropriate or if applicable;
FDA review and approval of the NDA or BLA prior to any commercial marketing or sale; and
compliance with any post-approval requirements, including the potential requirement to implement a Risk Evaluation
and Mitigation Strategy ("REMS") and the potential requirement to conduct post-approval studies.

Once a pharmaceutical product candidate is identified for development, it enters the preclinical testing stage. Preclinical tests include laboratory evaluations
of product chemistry, toxicity, formulation and stability, as well as animal studies. An IND sponsor must submit the results of the preclinical tests, together
with manufacturing information, analytical data and any available clinical data or literature, to the FDA as part of the IND. An IND is an exemption from
the  FDCA  that  allows  an  unapproved  product  to  be  shipped  in  interstate  commerce  for  use  in  an  investigational  clinical  trial  and  a  request  for  FDA
authorization to administer such investigational product to humans. The sponsor must also include a protocol detailing, among other things, the objectives
of the initial clinical trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated if the initial clinical trial lends itself
to an efficacy evaluation. Some preclinical testing may continue even after the IND is submitted. The IND automatically becomes effective 30 days after
receipt by the FDA, unless the FDA raises concerns or questions related to a proposed clinical trial and places the trial on a clinical hold within that 30-day
period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Clinical holds also may be
imposed by the FDA at any time before or during clinical trials due to safety concerns or non-compliance and may be imposed on all drug or biological
products within a certain class of drugs or biologics. The

27

FDA also can impose partial clinical holds, for example, prohibiting the initiation of clinical trials of a certain duration or for a certain dose.

All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with GCP regulations. These regulations
include the requirement that all research subjects provide informed consent in writing before their participation in any clinical trial. Further, an IRB must
review and approve the plan for any clinical trial before it commences at any institution, and the IRB must conduct continuing review and reapprove the
study  at  least  annually.  An  IRB  considers,  among  other  things,  whether  the  risks  to  individuals  participating  in  the  clinical  trial  are  minimized  and  are
reasonable in relation to anticipated benefits. The IRB also approves the information regarding the clinical trial and the consent form that must be provided
to each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed.

Each new clinical protocol and any amendments to the protocol must be submitted for FDA review and to the IRBs for approval. Protocols detail, among
other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject
safety.

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

Phase  1.  The  product  is  initially  introduced  into  a  small  number  of  healthy  human  subjects  or  patients  and  tested  for  safety,  dosage
tolerance,  absorption,  metabolism,  distribution  and  excretion  and,  if  possible,  to  gain  early  evidence  on  effectiveness.  In  the  case  of
some products for severe or life-threatening diseases, especially when the product is suspected or known to be unavoidably toxic, the
initial human testing may be conducted in patients.
Phase  2.  Involves  clinical  trials  in  a  limited  patient  population  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 and schedule.
Phase  3.  Clinical  trials  are  undertaken  to  further  evaluate  dosage,  clinical  efficacy  and  safety  in  an  expanded  patient  population  at
geographically  dispersed  clinical  trial  sites.  These  clinical  trials  are  intended  to  establish  the  overall  risk/benefit  relationship  of  the
product and provide an adequate basis for product labeling.

Post-approval  trials,  sometimes  referred  to  as  Phase  4  clinical  trials,  may  be  conducted  after  initial  marketing  approval.  These  studies  are  used  to  gain
additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, the FDA may mandate the performance of
Phase  4  trials.  Companies  that  conduct  certain  clinical  trials  are  also  required  to  register  them  and  post  the  results  of  completed  clinical  trials  on  a
government-sponsored  database,  such  as  ClinicalTrials.gov  in  the  United  States,  within  certain  timeframes.  Failure  to  do  so  can  result  in  fines,  adverse
publicity and civil and criminal sanctions.

Progress reports detailing the results of the clinical trials, among other information, must be submitted at least annually to the FDA, and written IND safety
reports must be submitted to the FDA and the investigators for serious and unexpected adverse events, findings from other studies that suggest a significant
risk  to  humans  exposed  to  the  product,  findings  from  animal  or  in  vitro  testing  that  suggest  a  significant  risk  to  human  subjects,  and  any  clinically
important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. Phase 1, Phase 2 and Phase 3
clinical trials may not be completed successfully within any specified period, if at all. The FDA or the clinical trial sponsor may suspend or terminate a
clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk.
Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the
IRB’s requirements or if the product has been associated with unexpected serious harm to patients. Additionally, some clinical trials are overseen by an
independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or committee. This group provides
authorization for whether a trial may move forward at designated check points based on access to certain data from the study. The clinical trial sponsor may
also suspend or terminate a clinical trial based on evolving business objectives and/or competitive climate.

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

FDA Review Process

The results of product development, preclinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted
on the drug or biologic, proposed labeling and other relevant information, are submitted to the FDA as part of an NDA or BLA, requesting approval to
market the product. An NDA for a new drug must contain proof of the drug’s safety and efficacy. A BLA is a request for approval to market a biologic for
one or more specified indications and must contain proof of the biologic’s safety, purity, and potency. Under federal law, the submission of most NDAs or
BLAs are subject to an application user fee, which for federal fiscal year 2021 is $2,875,842 for an NDA or BLA requiring clinical data. The sponsor of an
approved NDA or BLA

28

 
 
is also subject to an annual program fee, which for fiscal year 2021 is $336,432 for each product presentation. Certain exceptions and waivers are available
for some of these fees, such as an exception from the application fee for products with orphan designation and a waiver for certain small businesses.

The FDA reviews all NDAs and BLAs submitted before it accepts them for filing and may request additional information rather than accepting an NDA or
BLA for filing. The FDA typically makes a decision on accepting an NDA or BLA for filing within 60 days of receipt. The decision to accept the NDA or
BLA for filing means that the FDA has made a threshold determination that the application is sufficiently complete to permit a substantive review. Under
the goals and policies agreed to by the FDA under the Prescription Drug User Fee Act ("PDUFA"), the FDA’s goal to complete its substantive review and
respond to the applicant is ten months from the receipt of a standard NDA or ten months from the filing date of an NDA for a new molecular entity or
original BLA. The FDA does not always meet its PDUFA goal dates, and the review process is often significantly extended by FDA requests for additional
information or clarification and may go through multiple review cycles.

After  the  NDA  or  BLA  submission  is  accepted  for  filing,  the  FDA  reviews  the  NDA  or  BLA  to  determine,  among  other  things,  whether  the  proposed
product is safe and effective for its intended use, and whether the product is being manufactured in accordance with cGMPs to assure and preserve the
product’s identity, strength, quality and purity. The FDA may refer applications for novel drug or biological products or drug or biological products which
present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation
and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an
advisory committee, but it considers such recommendations carefully when making decisions. The FDA will likely re-analyze the clinical trial data, which
could result in extensive discussions between the FDA and us during the review process. The review and evaluation of an NDA or BLA by the FDA is
extensive and time consuming and may take longer than originally planned to complete, and we may not receive a timely approval, if at all.

Before  approving  an  NDA  or  BLA,  the  FDA  will  conduct  a  pre-approval  inspection  of  the  manufacturing  facilities  for  the  new  product  to  determine
whether  they  comply  with  cGMPs.  The  FDA  will  not  approve  the  product  unless  it  determines  that  the  manufacturing  processes  and  facilities  are  in
compliance  with  cGMP  requirements  and  adequate  to  assure  consistent  production  of  the  product  within  required  specifications.  In  addition,  before
approving an NDA or BLA, the FDA may also audit data from clinical trials to ensure compliance with GCP requirements. After the FDA evaluates the
application,  manufacturing  process  and  manufacturing  facilities,  it  may  issue  an  approval  letter  or  a  Complete  Response  Letter.  An  approval  letter
authorizes  commercial  marketing  of  the  drug  or  biologic  with  specific  prescribing  information  for  specific  indications.  A  Complete  Response  Letter
indicates that the review cycle of the application is complete and the application will not be approved in its present form. A Complete Response Letter
usually describes all the specific deficiencies in the NDA or BLA identified by the FDA. The Complete Response Letter may require additional clinical
data and/or an additional pivotal Phase 3 clinical trial(s), and/or other significant and time-consuming requirements related to clinical trials, nonclinical
studies  or  manufacturing.  If  a  Complete  Response  Letter  is  issued,  the  applicant  may  either  resubmit  the  NDA  or  BLA,  addressing  all  the  deficiencies
identified in the letter, or withdraw the application. Even if such data and information are submitted, the FDA may ultimately decide that the NDA or BLA
does not satisfy the criteria for approval. Data obtained from clinical trials are not always conclusive, and the FDA may interpret data differently than we
interpret the same data.

There is no assurance that the FDA will ultimately approve a product for marketing in the United States, and we may encounter significant difficulties or
costs during the review process. If a product receives marketing approval, the approval may be significantly limited to specific diseases and dosages or the
indications  for  use  may  otherwise  be  limited,  which  could  restrict  the  commercial  value  of  the  product.  Further,  the  FDA  may  require  that  certain
contraindications, warnings or precautions be included in the product labeling or may condition the approval of the NDA or BLA on other changes to the
proposed labeling, development of adequate controls and specifications, or a commitment to conduct post-market testing or clinical trials and surveillance
to monitor the effects of approved products. For example, the FDA may require Phase 4 clinical trials to further assess drug safety and effectiveness and
may require testing and surveillance programs to monitor the safety of approved products that have been commercialized. The FDA may also place other
conditions on approvals including the requirement for a REMS to assure the safe use of the drug. If the FDA concludes a REMS is needed, the sponsor of
the NDA must submit a proposed REMS; the FDA will not approve the NDA without an approved REMS, if required. A REMS could include medication
guides,  physician  communication  plans,  or  elements  to  assure  safe  use,  such  as  restricted  distribution  methods,  patient  registries  and  other  risk
minimization tools. Any of these limitations on approval or marketing could restrict the commercial promotion, distribution, prescription or dispensing of
products. Product approvals may be withdrawn for non-compliance with regulatory requirements or if problems occur following initial marketing.

Section 505(b)(2) NDAs

NDAs for most new drug products are based on two full clinical studies which must contain substantial evidence of the safety and effectiveness of the
proposed new product for the proposed use. These applications are submitted under Section 505(b)(1) of the FDCA. The FDA is authorized, however, to
approve  an  alternative  type  of  NDA  under  Section  505(b)(2)  of  the  FDCA.  This  type  of  application  allows  the  applicant  to  rely,  in  part,  on  the  FDA’s
previous findings of safety and effectiveness for a similar product, or published literature. Specifically, Section 505(b)(2) applies to NDAs for a drug for
which the investigations relied upon by the

29

applicant for approval of the application “were not conducted by or for the applicant and for which the applicant has not obtained a right of reference or use
from the person by or for whom the investigations were conducted.”

Thus, Section 505(b)(2) authorizes the FDA to approve an NDA based on safety and effectiveness data that were not developed by the applicant. NDAs
filed under Section 505(b)(2) may provide an alternate and potentially more expeditious pathway to FDA approval for new or improved formulations or
new uses of previously approved products. If the 505(b)(2) applicant can establish that reliance on the FDA’s previous approval is scientifically appropriate,
the applicant may eliminate the need to conduct certain preclinical or clinical studies of the new product. The FDA may also require companies to perform
additional studies or measurements to support the change from the approved product. The FDA may then approve the new 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 Section 505(b)(2) applicant.

Abbreviated New Drug Applications for Generic Drugs

In 1984, with passage of the Hatch-Waxman Amendments to the FDCA, Congress established an abbreviated regulatory scheme authorizing the FDA to
approve generic drugs that are shown to contain the same active ingredients as, and to be bioequivalent to, drugs previously approved by the FDA pursuant
to NDAs. To obtain approval of a generic drug, an applicant must submit an abbreviated new drug application ("ANDA") to the agency. An ANDA is a
comprehensive submission that contains, among other things, data and information pertaining to the active pharmaceutical ingredient, bioequivalence, drug
product  formulation,  specifications  and  stability  of  the  generic  drug,  as  well  as  analytical  methods,  manufacturing  process  validation  data  and  quality
control procedures. ANDAs are “abbreviated” because they generally do not include preclinical and clinical data to demonstrate safety and effectiveness.
Instead, in support of such applications, a generic manufacturer may rely on the preclinical and clinical testing previously conducted for a drug product
previously approved under an NDA, known as the reference-listed drug ("RLD").

Specifically,  in  order  for  an  ANDA  to  be  approved,  the  FDA  must  find  that  the  generic  version  is  the  same  as  the  RLD  with  respect  to  the  active
ingredients, the route of administration, the dosage form, the strength of the drug and the conditions of use of the drug. At the same time, the FDA must
also determine that the generic drug is “bioequivalent” to the innovator drug. Under the statute, a generic drug is bioequivalent to an RLD if the rate and
extent of absorption of the drug do not show a significant difference from the rate and extent of absorption of the RLD. Upon approval of an ANDA, the
FDA  indicates  whether  the  generic  product  is  “therapeutically  equivalent”  to  the  RLD  in  its  publication  “Approved  Drug  Products  with  Therapeutic
Equivalence Evaluations,” also referred to as the “Orange Book.” Physicians and pharmacists consider a therapeutic equivalent generic drug to be fully
substitutable for the RLD. In addition, by operation of certain state laws and numerous health insurance programs, the FDA’s designation of therapeutic
equivalence often results in substitution of the generic drug without the knowledge or consent of either the prescribing physician or patient.

Under  the  Hatch-Waxman  Amendments,  the  FDA  may  not  approve  an  ANDA  until  any  applicable  period  of  non-patent  exclusivity  for  the  RLD  has
expired. The FDCA provides a period of five years of non-patent data exclusivity for a new drug containing a new chemical entity. For the purposes of this
provision,  a  new  chemical  entity  ("NCE")  is  a  drug  that  contains  no  active  moiety,  which  is  the  molecule  or  ion  responsible  for  the  physiological  or
pharmacological action of the drug substance, that has previously been approved by the FDA in any other NDA. In cases where such NCE exclusivity has
been  granted,  an  ANDA  may  not  be  filed  with  the  FDA  until  the  expiration  of  five  years  unless  the  submission  is  accompanied  by  a  Paragraph  IV
certification,  which  states  that  the  proposed  drug  will  not  infringe  the  already  approved  product’s  listed  patents  or  that  such  patents  are  invalid  or
unenforceable, in which case the applicant may submit its application four years following the original product approval.

The  FDCA  also  provides  for  a  period  of  three  years  of  exclusivity  if  the  NDA  includes  reports  of  one  or  more  new  clinical  investigations,  other  than
bioavailability or bioequivalence studies, that were conducted by or for the applicant and are essential to the approval of the application. This three-year
exclusivity  period  often  protects  changes  to  a  previously  approved  drug  product,  such  as  a  new  dosage  form,  route  of  administration,  combination  or
indication.  Three-year  exclusivity  would  be  available  for  a  drug  product  that  contains  a  previously  approved  active  moiety,  provided  the  statutory
requirement for a new clinical investigation is satisfied. Unlike five-year NCE exclusivity, an award of three-year exclusivity does not block the FDA from
accepting  ANDAs  seeking  approval  for  generic  versions  of  the  drug  as  of  the  date  of  approval  of  the  original  drug  product.  The  FDA  typically  makes
decisions about awards of data exclusivity shortly before a product is approved.

Pursuant  to  the  Food  and  Drug  Administration  Reauthorization  Act  of  2017,  the  FDA  must  establish  a  priority  review  track  for  certain  generic  drugs,
requiring the FDA to review a drug application within eight (8) months for a drug that has three (3) or fewer approved drugs listed in the Orange Book and
is no longer protected by any patent or regulatory exclusivities, or is on the FDA’s drug shortage list. The new legislation also authorizes FDA to expedite
review of ‘‘competitive generic therapies’’ or drugs with inadequate generic competition, including holding meetings with or providing advice to the drug
sponsor prior to submission of the application.

Marketing Exclusivity for Biological Products

An abbreviated approval pathway for biological products shown to be biosimilar to or interchangeable with an FDA-licensed reference biological product
was created by the Biologics Price Competition and Innovation Act of 2009 ("BPCI Act"). This amendment to the

30

PHSA, in part, attempts to minimize duplicative testing. Biosimilarity, which requires that the biological product be highly similar to the reference product
notwithstanding  minor  differences  in  clinically  inactive  components  and  that  there  be  no  clinically  meaningful  differences  between  the  product  and  the
reference  product  in  terms  of  safety,  purity,  and  potency,  can  be  shown  through  analytical  studies,  animal  studies,  and  a  clinical  trial  or  trials.
Interchangeability requires that a biological product be biosimilar to the reference product and that the product can be expected to produce the same clinical
results  as  the  reference  product  in  any  given  patient  and,  for  products  administered  multiple  times  to  an  individual,  that  the  product  and  the  reference
product may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to
exclusive use of the reference biological product without such alternation or switch.

A  reference  biological  product  is  granted  12  years  of  data  exclusivity  from  the  time  of  first  licensure  of  the  product,  and  the  FDA  will  not  accept  an
application  for  a  biosimilar  or  interchangeable  product  based  on  the  reference  biological  product  until  four  years  after  the  date  of  first  licensure  of  the
reference product. ‘‘First licensure’’ typically means the initial date the particular product at issue was licensed in the United States. Date of first licensure
does not include the date of licensure of (and a new period of exclusivity is not available for) a biological product if the licensure is for a supplement for the
biological product or for a subsequent application by the same sponsor or manufacturer of the biological product (or licensor, predecessor in interest, or
other  related  entity)  for  a  change  (not  including  a  modification  to  the  structure  of  the  biological  product)  that  results  in  a  new  indication,  route  of
administration, dosing schedule, dosage form, delivery system, delivery device or strength, or for a modification to the structure of the biological product
that does not result in a change in safety, purity, or potency.

Hatch-Waxman Patent Certification and the 30-Month Stay

Upon approval of an NDA, including a 505(b)(2) NDA, or a supplement thereto, NDA sponsors are required to list with the FDA each patent with claims
that cover the applicant’s product or an approved method of using the product. Each of the patents listed by the NDA sponsor is published in the Orange
Book. When an ANDA applicant files its application with the FDA, the applicant is required to certify to the FDA concerning any patents listed for the
reference product in the Orange Book, except for patents covering methods of use for which the ANDA applicant is not seeking approval. To the extent that
the Section 505(b)(2) applicant relies on studies conducted for an already approved product, the applicant is required to certify to the FDA concerning any
patents listed for the approved product in the Orange Book to the same extent that an ANDA applicant would.

Specifically, the applicant must certify with respect to each patent that:

<

<

<

<

the required patent information has not been filed;
the listed patent has expired;
the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or
the listed patent is invalid, unenforceable or will not be infringed by the new product.

A certification that the new product will not infringe the already approved product’s listed patents or that such patents are invalid or unenforceable is called
a  Paragraph  IV  certification.  If  the  applicant  does  not  provide  a  Paragraph  IV  certification  against  the  listed  patents  or  indicates  that  it  is  not  seeking
approval of a patented method of use, the application will not be approved until all the listed patents claiming the referenced product have expired (other
than method of use patents involving indications for which the applicant is not seeking approval).

If  the  ANDA  or  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 the 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 after the receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA or 505(b)(2) application
until the earlier of 30 months after the receipt of the Paragraph IV notice, expiration of the patent, or a decision in the infringement case that is favorable to
the applicant. The ANDA or 505(b)(2) application also will not be approved until any applicable non-patent exclusivity listed in the Orange Book for the
branded reference drug has expired.

Regulation of Combination Products in the United States

Certain products may be comprised of components, such as drug components and device components, that would normally be regulated under different
types  of  regulatory  authorities,  and  frequently  by  different  centers  at  the  FDA.  These  products  are  known  as  combination  products.  Specifically,  under
regulations issued by the FDA, a combination product may be:

<

<

a  product  comprised  of  two  or  more  regulated  components  that  are  physically,  chemically,  or  otherwise  combined  or  mixed  and
produced as a single entity;
two or more separate products packaged together in a single package or as a unit and comprised of drug and device products, device and
biological products, or biological and drug products;

31

 
 
 
 
<

<

a drug, device, or biological product packaged separately that according to its investigational plan or proposed labeling is intended for
use only with an approved individually specified drug, or device, or biological product where both are required to achieve the intended
use,  indication,  or  effect  and  where  upon  approval  of  the  proposed  product  the  labeling  of  the  approved  product  would  need  to  be
changed, e.g., to reflect a change in intended use, dosage form, strength, route of administration, or significant change in dose; or
any investigational drug, device, or biological product packaged separately that according to its proposed labeling is for use only with
another individually specified investigational drug, device, or biological product where both are required to achieve the intended use,
indication, or effect.

Under the FDCA and its implementing regulations, the FDA is charged with assigning a center with primary jurisdiction, or a lead center, for review of a
combination  product.  The  designation  of  a  lead  center  generally  eliminates  the  need  to  receive  approvals  from  more  than  one  FDA  component  for
combination products, although it does not preclude consultations by the lead center with other components of FDA. The determination of which center
will  be  the  lead  center  is  based  on  the  “primary  mode  of  action”  of  the  combination  product.  Thus,  if  the  primary  mode  of  action  of  a  drug-device
combination  product  is  attributable  to  the  drug  product,  the  FDA  center  responsible  for  premarket  review  of  the  drug  product  would  have  primary
jurisdiction  for  the  combination  product.  The  FDA  also  has  established  an  Office  of  Combination  Products  to  address  issues  surrounding  combination
products  and  provide  more  certainty  to  the  regulatory  review  process.  That  office  serves  as  a  focal  point  for  combination  product  issues  for  agency
reviewers and industry. It is also responsible for developing guidance and regulations to clarify the regulation of combination products and for assignment
of the FDA center that has primary jurisdiction for review of combination products where the jurisdiction is unclear or in dispute.

A combination product with a drug primary mode of action generally would be reviewed and approved pursuant to the drug approval processes under the
FDCA. In reviewing the NDA or 505(b)(2) application for such a product, however, FDA reviewers in the drug center could consult with their counterparts
in the device center to ensure that the device component of the combination product met applicable requirements regarding safety, effectiveness, durability
and  performance.  In  addition,  under  FDA  regulations,  combination  products  are  subject  to  cGMP  requirements  applicable  to  both  drugs  and  devices,
including the Quality System ("QS") regulations applicable to medical devices.

Drug-device  combination  products  present  unique  challenges  for  competitors  seeking  approval  of  an  ANDA  for  generic  versions  of  combination
products. Generally, FDA reviews both the drug and device constituents of a proposed generic product to determine whether it is the same as the innovator
product,  including  whether  the  basic  design  and  operating  principles  of  the  device  component  are  the  same  and  whether  minor  differences  require
significant differences in labeling for safe and effective use. If FDA determines that the device component of the proposed generic product is not the same
in terms of performance and critical design, or that the labeling is not the same, it generally will not approve the ANDA. Likewise, if FDA determines that
certain  clinical  studies,  such  as  clinical  usability  or  human  factors  studies,  are  necessary  to  demonstrate  the  safety  and/or  effectiveness  of  the  device
component, FDA generally will not accept or approve an ANDA for a combination product and will instead require the submission of a full NDA or 505(b)
(2) application.

Post-Marketing Requirements

Any  products  for  which  we  receive  FDA  approval  are  subject  to  continuing  regulation  by  the  FDA,  including,  among  other  things,  monitoring  and
recordkeeping  activities,  reporting  to  the  applicable  regulatory  authorities  of  adverse  events  with  the  product,  providing  the  applicable  regulatory
authorities  with  updated  safety  and  efficacy  information,  and  product  sampling  and  distribution  requirements  in  accordance  with  the  Prescription  Drug
Marketing Act ("PDMA"), a part of the FDCA, as well as the Drug Supply Chain Security Act ("DSCSA"). The PDMA, its implementing regulations and
state  laws  limit  the  distribution  of  prescription  pharmaceutical  product  samples,  and  the  DSCSA  imposes  requirements  to  ensure  accountability  in
distribution and to identify and remove counterfeit and other illegitimate products from the market. Moreover, each component of a combination product
retains its regulatory status (as a drug or device, for example) and is subject to the requirements established by the FDA for that type of component. The
FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the market.

Prescription drug and biologic advertising is subject to federal, state and foreign regulations. In the United States, the FDA regulates prescription drug and
biologic promotion and advertising, including direct-to-consumer advertising. Prescription drug and biologic promotional materials must be submitted to
the FDA in conjunction with their first use. In addition, a pharmaceutical company must comply with restrictions on promoting drugs and biologics for uses
or in patient populations that are not described in the drug’s or biologic's approved labeling (known as “off-label use”), limitations on industry-sponsored
scientific and educational activities, and requirements for promotional activities involving the internet. Although physicians may prescribe legally available
drugs or biologics for off-label uses, manufacturers are prohibited from marketing or promoting such off-label uses.

In the United States, once a product is approved, its manufacture is subject to comprehensive and continuing regulation by the FDA. The FDA regulations
require that combination products be manufactured in specific approved facilities and in accordance with cGMPs

32

applicable to drugs, biologics and devices, including certain QS requirements. We rely, and expect to continue to rely, on third parties for the production of
clinical and commercial quantities of our products in accordance with cGMP regulations. cGMP regulations require among other things, quality control and
quality assurance as well as the corresponding maintenance of records and documentation and the obligation to investigate and correct any deviations from
cGMP. Drug and biologics manufacturers and other entities involved in the manufacture and distribution of approved drugs or biologics are required to
register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state
agencies  for  compliance  with  cGMPs  and  other  laws.  Accordingly,  manufacturers  must  continue  to  expend  time,  money,  and  effort  in  the  area  of
production  and  quality  control  to  maintain  cGMP  compliance.  These  regulations  also  impose  certain  organizational,  procedural  and  documentation
requirements with respect to manufacturing and quality assurance activities. NDA or BLA holders using contract manufacturers, laboratories or packagers
are responsible for the selection and monitoring of qualified firms, and, in certain circumstances, qualified suppliers to these firms. These firms and, where
applicable,  their  suppliers  are  subject  to  inspections  by  the  FDA  at  any  time,  and  the  discovery  of  violative  conditions,  including  failure  to  conform  to
cGMPs, could result in enforcement actions that interrupt the operation of any such facilities or the ability to distribute products manufactured, processed
or tested by them. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved
NDA or BLA, including, among other things, recall or withdrawal of the product from the market.

The FDA also may require post-marketing testing, known as Phase 4 testing, REMS and surveillance to monitor the effects of an approved product or place
conditions on an approval that could restrict the distribution or use of the product. Discovery of previously unknown problems with a product or the failure
to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, untitled
or warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly
discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and
contraindications, and may require the implementation of other risk management measures. Also, new government requirements, including those resulting
from  new  legislation,  may  be  established,  or  the  FDA’s  policies  may  change,  which  could  delay  or  prevent  regulatory  approval  of  our  products  under
development and impact approved products already on the market.

Other Regulatory Matters

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage
and security requirements intended to prevent the unauthorized sale of pharmaceutical products.

The failure to comply with regulatory requirements subjects firms to possible legal or regulatory action. Depending on the circumstances, failure to meet
applicable  regulatory  requirements  can  result  in  criminal  prosecution,  fines  or  other  penalties,  injunctions,  voluntary  recall,  seizure  of  products,  total  or
partial suspension of production, denial or withdrawal of product approvals, exclusion from federal healthcare programs, or refusal to allow a firm to enter
into supply contracts, including government contracts. In addition, even if a firm complies with FDA and other requirements, new information regarding
the safety or effectiveness of a product could lead the FDA to modify or withdraw product approval. Prohibitions or restrictions on sales or withdrawal of
future products marketed by us could materially affect our business in an adverse way.

Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to
our  manufacturing  arrangements;  (ii)  additions  or  modifications  to  product  labeling;  (iii)  the  voluntary  recall  or  discontinuation  of  our  products;  or
(iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.

Orphan Designation and Exclusivity

The FDA may grant orphan drug designation to drugs intended to treat a rare disease or condition that affects fewer than 200,000 individuals in the United
States. Alternatively, orphan drug designation may be available if the disease or the condition affects more than 200,000 individuals in the United States
and there is no reasonable expectation that the cost of developing and making the drug for this type of disease or condition will be recovered from sales in
the United States.

Orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-
fee waivers. If a product with orphan designation receives the first FDA approval for the disease or condition for which it has such designation or for a
select indication or use within the rare disease or condition for which it was designated, the product generally will receive orphan drug exclusivity. Orphan
drug exclusivity means that the FDA may not approve another sponsor’s marketing application for the same drug for the same condition for seven years,
except in certain limited circumstances. Orphan exclusivity does not block the approval of a different drug for the same rare disease or condition, nor does
it  block  the  approval  of  the  same  drug  for  different  conditions.  If  a  drug  designated  as  an  orphan  drug  ultimately  receives  marketing  approval  for  an
indication broader than what was designated in its orphan drug application, it may not be entitled to exclusivity.

Orphan drug exclusivity will not bar approval of another product with the same drug for the same condition under certain circumstances, including if a
subsequent product with the same drug for the same condition is shown to be clinically superior to the

33

approved product on the basis of greater efficacy or safety, or providing a major contribution to patient care, or if the company with orphan drug exclusivity
cannot  assure  the  availability  of  sufficient  quantities  of  the  drug  to  meet  the  needs  of  persons  with  the  disease  or  condition  for  which  the  drug  was
designated.

Pediatric Studies and Exclusivity

Under the Pediatric Research Equity Act of 2003, as amended, an NDA or supplement thereto must contain data to assess the safety and effectiveness of
the product for the claimed indications in all relevant pediatric subpopulations, and to support dosing and administration for each pediatric subpopulation
for which the product is safe and effective. A sponsor who is planning to submit a marketing application for a drug product that includes a new active
ingredient,  new  indication,  new  dosage  form,  new  dosing  regimen  or  new  route  of  administration  must  submit  an  initial  Pediatric  Study  Plan  ("PSP")
within sixty days of an end-of-Phase 2 meeting or as may be agreed between the sponsor and the FDA. The initial PSP must include an outline of the
pediatric study or studies that the sponsor plans to conduct, including study objectives and design, age groups, relevant endpoints and statistical approach,
or  a  justification  for  not  including  such  detailed  information,  and  any  request  for  a  deferral  of  pediatric  assessments  or  a  full  or  partial  waiver  of  the
requirement to provide data from pediatric studies along with supporting information. The FDA may, on its own initiative or at the request of the applicant,
grant deferrals for submission of some or all pediatric data until after approval of the product for use in adults or full or partial waivers if certain criteria are
met. The FDA and the sponsor must reach agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial PSP at any time if changes to
the  pediatric  plan  need  to  be  considered  based  on  data  collected  from  preclinical  studies,  early  phase  clinical  trials,  and/or  other  clinical  development
programs. The requirements for pediatric data generally do not apply to drugs or biologics for an indication for which orphan designation has been granted.

Pediatric exclusivity is another type of non-patent exclusivity in the United States and, if granted, provides for the attachment of an additional six months
of marketing protection to the term of any existing regulatory exclusivity, including the non-patent five-year and three-year and orphan exclusivity. This
six-month exclusivity may be granted if an NDA or BLA sponsor submits pediatric data that fairly respond to a written request from the FDA for such data.
The data do not need to show the product to be effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the
FDA’s  request,  the  additional  protection  is  granted.  If  reports  of  FDA-requested  pediatric  studies  are  submitted  to  and  accepted  by  the  FDA  within  the
statutory time limits, whatever statutory or regulatory periods of exclusivity or patent protection cover the product are extended by six months. This is not a
patent term extension, but it effectively extends the regulatory period during which the FDA cannot approve another application.

Expedited Review and Approval Programs

A sponsor may seek approval of its product candidate under programs designed to accelerate the FDA’s review and approval of new drugs and biological
products that meet certain criteria. Specifically, new drugs and biological products are eligible for Fast Track designation if they are intended to treat a
serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for that disease or condition. For a Fast Track
product, the FDA may consider sections of the NDA or BLA for review on a rolling basis before the complete application is submitted if relevant criteria
are met. In October 2020, we were granted Fast Track designation by the FDA for our novel formulation of diazepam.

A product candidate may also qualify for priority review, under which the FDA generally sets the target date for FDA action on the NDA or BLA that is
subject to the prescription drug user fee amendments ("PDUFA") goals at six months after the FDA accepts the application for filing, or for drugs that are
not new chemical entities, six months after the FDA receives the application. Priority review is granted when there is evidence that the proposed product
would be a significant improvement in the safety or effectiveness of the treatment, diagnosis, or prevention of a serious condition. If criteria are not met for
priority review, the application is subject to the standard FDA PDUFA review period of ten months after the FDA accepts the application for filing, or for
drugs  that  are  not  new  chemical  entities,  ten  months  after  FDA  receives  the  application.  Priority  review  designation  does  not  change  the  scientific  or
medical standard for approval or the quality of evidence necessary to support approval.

Under the accelerated approval program, the FDA may approve an NDA or BLA on the basis of either a surrogate endpoint that is reasonably likely to
predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an
effect  on  irreversible  morbidity  or  mortality  or  other  clinical  benefit,  taking  into  account  the  severity,  rarity,  or  prevalence  of  the  condition  and  the
availability or lack of alternative treatments. Post-marketing studies or completion of ongoing studies after regulatory approvals are generally required to
verify the drug or biologic’s clinical benefit in relationship to the surrogate endpoint or ultimate outcome in relationship to the clinical benefit. Drugs or
Biologics  granted  accelerated  approval  may  be  subject  to  expedited  withdrawal  procedures  if  the  product  sponsor  fails  to  conduct  the  required  post-
marketing studies, or if such post-marketing studies fail to verify a clinical benefit.

The  FDA  also  may  designate  a  product  candidate  as  a  Breakthrough  Therapy  if  it  is  intended,  either  alone  or  in  combination  with  one  or  more  other
products, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the product may demonstrate substantial
improvement  over  existing  therapies  on  one  or  more  clinically  significant  endpoints,  such  as  substantial  treatment  effects  observed  early  in  clinical
development. Breakthrough Therapy designation includes all of the Fast Track

34

program features, as well as more intensive FDA interaction and guidance. The Breakthrough Therapy designation is a distinct status from both accelerated
approval and priority review, which also can be granted to the same drug or biologic if relevant criteria are met. If a product is designated as Breakthrough
Therapy, the FDA will work to expedite the development and review of such product.

Fast Track designation, Breakthrough Therapy designation and priority review do not change the standards for approval but may expedite the development
or  approval  process.  Even  if  a  product  qualifies  for  one  or  more  of  these  programs,  the  FDA  may  later  decide  that  the  product  no  longer  meets  the
conditions for qualification or decide that the time period for FDA review or approval will not be shortened.

Regulations and Procedures Governing Approval of Medicinal Products in the European Union

In  order  to  market  any  product  outside  the  United  States,  a  company  must  also  comply  with  numerous  and  varying  regulatory  requirements  of  other
countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial
sales and distribution of products. Whether or not it obtains FDA approval for a product, an applicant will need to obtain the necessary approvals by the
comparable  non-U.S.  regulatory  authorities  before  it  can  commence  clinical  trials  or  marketing  of  the  product  in  those  countries  or  jurisdictions.
Specifically, the process governing approval of medicinal products in the EU generally follows the same lines as in the United States. It entails satisfactory
completion of pharmaceutical development, preclinical studies and adequate and well-controlled clinical trials to establish the safety and efficacy of the
medicinal product for each proposed indication. It also requires the submission to the relevant competent authorities for clinical trials authorization and to
the EMA for an MAA and granting of a marketing authorization by these authorities before the product can be marketed and sold in the EU.

European Orphan Designation and Exclusivity

In the EU, the EMA’s Committee for Orphan Medicinal Products ("COMP") grants orphan drug designation to promote the development of products that
are  intended  for  the  diagnosis,  prevention  or  treatment  of  life-threatening  or  chronically  debilitating  conditions  that  affect  not  more  than  five  in  10,000
persons in the EU Community, or when, without incentives, it is unlikely that sales of such products in the EU would be sufficient to justify the necessary
investment in developing the products. Additionally, orphan drug designation is only available where no satisfactory method of diagnosis, prevention, or
treatment of the condition has been authorized (or the product would be a significant benefit to those affected).

In the EU, orphan drug designation entitles a party to financial incentives such as reduction of fees or fee waivers, and 10 years of market exclusivity is
granted following medicinal product approval. This period may be reduced to six years if the orphan drug designation criteria are no longer met, including
where  it  is  shown  that  the  product  is  sufficiently  profitable  not  to  justify  maintenance  of  market  exclusivity.  Market  exclusivity  would  not  prevent  the
approval of a similar drug that is shown to be safer, more effective or otherwise clinically superior.

Other Healthcare Laws and Compliance Requirements

In  addition  to  FDA  restrictions  on  the  marketing  of  pharmaceutical  products  and  medical  devices,  we  may  be  subject  to  various  federal  and  state  laws
targeting  fraud  and  abuse  in  the  healthcare  industry.  Although  we  do  not  provide  healthcare  services,  submit  claims  for  third-party  reimbursement,  or
receive payments directly from Medicare, Medicaid or other third-party payors for our products, we are subject to broadly applicable healthcare fraud and
abuse regulation and enforcement by federal and state governments, which could significantly impact our business. Manufacturing, sales, promotion and
other activities following product approval are also subject to regulation by numerous regulatory authorities in the United States in addition to the FDA,
including  the  Centers  for  Medicare  &  Medicaid  Services  ("CMS"),  other  divisions  of  the  Department  of  Health  and  Human  Services  ("HHS"),  the
Department of Justice ("DOJ"), the Drug Enforcement Administration ("DEA"), the Consumer Product Safety Commission ("CPSC"), the Federal Trade
Commission  ("FTC"),  the  Occupational  Safety  &  Health  Administration  ("OSHA"),  the  Environmental  Protection  Agency  ("EPA"),  and  state  and  local
governments.  These  laws  may  impact,  among  other  things,  our  proposed  sales,  marketing  and  education  programs.  In  addition,  we  may  be  subject  to
patient privacy regulation by both the federal government and the states in which we conduct our business. The laws that may affect our ability to operate
include:

35

<

Anti-Kickback Statute ("AKS"). The federal AKS makes it illegal for any person or entity (including a prescription drug manufacturer
or a party acting on its behalf) to knowingly and willfully solicit, offer, receive or pay any remuneration (including any kickback, bribe
or certain rebate), directly or indirectly, overtly or covertly, in cash or in kind, in exchange for or intended to induce or reward either the
referral  of  an  individual  for,  or  the  purchase,  order,  prescription  or  recommendation  or  arranging  of,  any  good  or  service,  for  which
payment may be made under a federal healthcare program such as Medicare and Medicaid. This statute has been interpreted to apply to
arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers and formulary managers on the other.
Although there are several statutory exceptions and regulatory safe harbors protecting certain common activities from prosecution, they
are  drawn  narrowly,  and  practices  that  involve  remuneration  intended  to  induce  prescribing,  purchasing  or  recommending  may  be
subject to scrutiny if they do not qualify for an exception or safe harbor. A person or entity can be found guilty of violating the AKS
without  actual  knowledge  of  the  statute  or  specific  intent  to  violate  it.  In  addition,  the  government  may  assert  that  a  claim  including
items or services resulting from a violation of the AKS constitutes a false or fraudulent claim for purposes of the federal False Claims
Act or federal civil money penalties statute. Violations of the AKS carry potentially significant civil and criminal penalties, including
imprisonment, fines, administrative civil monetary penalties, and exclusion from participation in federal healthcare programs. This law
applies to our marketing practices, educational programs, pricing policies and relationships with healthcare providers, by prohibiting,
among other things, soliciting, receiving, offering or providing remuneration intended to induce the purchase or recommendation of an
item or service reimbursable under a federal healthcare program, such as the Medicare or Medicaid programs. On December 2, 2020, the
Office of Inspector General ("OIG") published further modifications to the federal Anti-Kickback Statute in the Federal Register. Under
the  final  rule,  the  OIG  added  safe  harbor  protections  under  the  Anti-Kickback  Statute  for  certain  coordinated  care  and  value-based
arrangements  among  clinicians,  providers,  and  others.  On  the  same  day,  CMS  published  a  final  rule  that  provides  a  safe  harbor  for
value-based compensation agreements under the Stark Law. However, the U.S. Government Accountability Office ("GAO") found that
these final rules did not meet the sixty-day delay required under the Congressional Review Act. Additionally, on January 20, 2021, the
Biden  Administration  issued  a  moratorium  on  all  Trump-era  rules  that  have  not  yet  taken  effect.  The  interplay  between  the  GAO’s
findings and the Biden Administration’s moratorium, which will determine whether these two rules are in effect, is unclear;
federal  civil  and  criminal  false  claims  laws  and  civil  monetary  penalties  laws,  such  as  the  federal  False  Claims  Act  (“FCA”),  which
impose  criminal  and  civil  penalties  and  authorize  civil  whistleblower  or  qui  tam  actions,  against  individuals  or  entities  (including
manufacturers) for, among other things: knowingly presenting, or causing to be presented, to a federal government healthcare program,
claims for payment or approval that are false, fictitious or fraudulent; knowingly making, using or causing to be made or used, a false
statement or record material to payment of a false or fraudulent claim or obligation to pay or transmit money or property to the federal
government; or knowingly concealing or knowingly and improperly avoiding or decreasing an obligation to pay money to the federal
government. The government may deem manufacturers to have “caused” the submission of false or fraudulent claims by, for example,
providing inaccurate billing or coding information to customers or promoting a product off-label. Companies that submit claims directly
to payors may also be liable under the FCA for the direct submission of such claims. The FCA also permits a private individual acting as
a  “whistleblower”  to  bring  actions  on  behalf  of  the  federal  government  alleging  violations  of  the  FCA  and  to  share  in  any  monetary
recovery. When an entity is determined to have violated the federal civil False Claims Act, the government may impose civil fines and
penalties for each false claim, plus treble damages, and exclude the entity from participation in Medicare, Medicaid and other federal
healthcare programs. Our marketing and activities relating to the reporting of wholesaler or estimated retail prices for our products, the
reporting  of  prices  used  to  calculate  Medicaid  rebate  information  and  other  information  affecting  federal,  state  and  third-party
reimbursement for our products, and the sale and marketing of our products and any future product candidates are subject to scrutiny
under this law;
the anti-inducement law, which prohibits, among other things, the offering or giving of remuneration, which includes, without limitation,
any  transfer  of  items  or  services  for  free  or  for  less  than  fair  market  value  (with  limited  exceptions),  to  a  Medicare  or  Medicaid
beneficiary that the person knows or should know is likely to influence the beneficiary’s selection of a particular provider, practitioner or
supplier of items or services reimbursable by a federal or state healthcare program;
the federal Health Insurance Portability and Accountability Act of 1996 ("HIPAA"), and its implementing regulations, which prohibit
knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of
false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of,
any healthcare benefit program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or
covering  up  by  any  trick  or  device  a  material  fact  or  making  any  materially  false  statements  in  connection  with  the  delivery  of,  or
payment for, healthcare benefits, items or services relating to healthcare 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 in order to have committed a violation;

36

HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act  of  2009  ("HITECH"),  and  their
respective implementing regulations, which impose requirements on certain covered healthcare providers, health plans, and healthcare
clearinghouses (“covered entities”) as well as their respective business associates that perform services for them that involve the use, or
disclosure of, individually identifiable health information, relating to the privacy, security and transmission of individually identifiable
health  information,  including  mandatory  contractual  terms  and  required  implementation  of  technical  safeguards  of  such  information.
HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to
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 pursing federal civil actions;
the  federal  false  statements  statute,  which  prohibits  knowingly  and  willfully  falsifying,  concealing  or  covering  up  a  material  fact  or
making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services;
the federal transparency requirements under the Affordable Care Act, including the Physician Payments Sunshine Act, which require
manufacturers  of  drugs,  devices,  biologics  and  medical  supplies  for  which  payment  is  available  under  Medicare,  Medicaid  or  the
Children’s Health Insurance Program to report annually to the HHS, information related to payments or other “transfers of value” made
or  distributed  to  certain  healthcare  professionals  and  teaching  hospitals,  as  well  as  ownership  and  investment  interests  held  by  the
healthcare professionals described above and their immediate family members. Failure to submit required information may result in civil
monetary  penalties  for  all  payments,  transfers  of  value  or  ownership  or  investment  interests  that  are  not  timely,  accurately,  and
completely reported in an annual submission. Effective January 1, 2022, these reporting obligations will extend to include transfers of
value made to certain additional healthcare professionals;
federal  price  reporting  laws,  which  require  manufacturers  to  calculate  and  report  complex  pricing  metrics  in  an  accurate  and  timely
manner to government programs;
federal  consumer  protection  and  unfair  competition  laws,  which  broadly  regulate  marketplace  activities  and  activities  that  potentially
harm consumers; and
The Foreign Corrupt Practices Act ("FCPA"), which prohibits companies and their intermediaries from making, or offering or promising
to  make,  improper  payments  to  non-U.S.  officials  for  the  purpose  of  obtaining  or  retaining  business  or  otherwise  seeking  favorable
treatment.

Additionally, we may be subject to state and non-U.S. equivalents of each of the healthcare laws described above, among others, some of which may be
broader in scope and may apply regardless of the payor. Many U.S. states have adopted laws similar to the federal Anti-Kickback Statute, some of which
apply  to  the  referral  of  patients  for  healthcare  services  reimbursed  by  any  source,  not  just  governmental  payors,  including  private  insurers.  In  addition,
some  states  have  passed  laws  that  require  pharmaceutical  companies  to  comply  with  the  April  2003  Office  of  Inspector  General  Compliance  Program
Guidance  for  Pharmaceutical  Manufacturers  and/or  the  Pharmaceutical  Research  and  Manufacturers  of  America’s  Code  on  Interactions  with  Healthcare
Professionals. Several states also impose other marketing restrictions or require pharmaceutical companies to make marketing or price disclosures to the
state.  There  are  ambiguities  as  to  what  is  required  to  comply  with  these  state  requirements,  and  if  we  fail  to  comply  with  an  applicable  state  law
requirement, we could be subject to penalties. Finally, there are state and non-U.S. laws governing the privacy and security of health information, many of
which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business
activities could be subject to challenge under one or more of such laws.

Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including penalties, fines, disgorgement, imprisonment and/or
exclusion  or  suspension  from  federal  and  state  healthcare  programs  such  as  Medicare  and  Medicaid  and  debarment  from  contracting  with  the  U.S.
government. In addition, private individuals have the ability to bring actions on behalf of the U.S. government under the federal False Claims Act as well as
under the false claims laws of several states.

Law enforcement authorities are increasingly focused on enforcing these laws, and it is possible that some of our practices may be challenged under these
laws.  Efforts  to  ensure  that  our  current  and  future  business  arrangements  with  third  parties,  and  our  business  generally,  will  comply  with  applicable
healthcare  laws  and  regulations  will  involve  substantial  costs.  It  is  possible  that  governmental  authorities  will  conclude  that  our  business  practices,
including our arrangements with physicians and other healthcare providers, some of whom receive stock options as compensation for services provided,
may not comply with current or future statutes, regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws and
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  civil,  criminal  and  administrative  penalties,  damages,  disgorgement,  monetary  fines,
imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm,
diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our
results of operations. In addition, the approval and commercialization of any of our drug candidates outside the United States also will likely subject us to
non-U.S. equivalents of the healthcare laws mentioned above, among other non-U.S. laws.

37

If any of the physicians or other healthcare providers or entities with whom we expect to do business are found to be not in compliance with applicable
laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs, which also may
adversely affect our business.

We may be 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.  From  time  to  time  and  in  the  future,  our  operations  may  involve  the  use  of
hazardous and flammable materials, including chemicals and biological materials, and may also produce hazardous waste products. Even if we contract
with third parties for the disposal of these materials and waste products, we cannot completely eliminate the risk of contamination or injury resulting from
these  materials.  In  the  event  of  contamination  or  injury  resulting  from  the  use  or  disposal  of  our  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.

We maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees, but this insurance may
not provide adequate coverage against potential liabilities. However, we do not maintain insurance for environmental liability or toxic tort claims that may
be asserted against us.

In  addition,  we  may  incur  substantial  costs  in  order  to  comply  with  current  or  future  environmental,  health  and  safety  laws  and  regulations.  Current  or
future environmental laws and regulations may impair our research, development or production efforts. In addition, failure to comply with these laws and
regulations may result in substantial fines, penalties or other sanctions.

Healthcare Reform

A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and other third-party payors have attempted to
control costs by limiting coverage and the amount of reimbursement for particular medical products. For example, in March 2010, the Affordable Care Act
("ACA") was enacted, which, among other things, increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate
Program; introduced 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 Medicaid Drug Rebate Program to utilization of prescriptions of individuals enrolled in
Medicaid managed care plans; imposed mandatory discounts for certain Medicare Part D beneficiaries as a condition for manufacturers’ outpatient drugs
coverage under Medicare Part D; subjected drug manufacturers to new annual fees based on pharmaceutical companies’ share of sales to federal healthcare
programs; imposed a new federal excise tax on the sale of certain medical devices; created a new Patient Centered Outcomes Research Institute to oversee,
identify priorities in and conduct comparative clinical effectiveness research, along with funding for such research; and established the Center for Medicare
Innovation at the CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending.

Since  its  enactment,  some  of  the  provisions  of  the  ACA  have  yet  to  be  fully  implemented,  while  certain  provisions  have  been  subject  to  judicial,
administrative,  executive,  and  legislative  challenges.  We  expect  there  will  be  additional  challenges  and  amendments  to  the  ACA  in  the  future.  Various
portions of the ACA are currently undergoing legal and constitutional challenges in the United States Supreme Court. The Trump Administration issued
various  Executive  Orders  that  eliminated  cost  sharing  subsidies  and  various  provisions  that  would  impose  a  fiscal  burden  on  states  or  a  cost,  fee,  tax,
penalty or regulatory burden on individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices.

Additionally,  Congress  has  considered  legislation  that  would  repeal  or  repeal  and  replace  all  or  part  of  the  ACA.  While  Congress  has  not  passed
comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs
Act of 2017 ("Tax Act") includes a provision that decreased the tax-based shared responsibility payment imposed by the ACA on certain individuals who
fail to maintain qualifying health coverage for all or part of a year, commonly referred to as the “individual mandate,” to $0, effective January 1, 2019. On
December 14, 2018, a federal district court in Texas ruled the individual mandate is a critical and inseverable feature of the ACA, and therefore, because it
was  repealed  as  part  of  the  Tax  Act,  the  remaining  provisions  of  the  ACA  are  invalid  as  well.  On  December  18,  2019,  the  Fifth  Circuit  U.S.  Court  of
Appeals held that the individual mandate is unconstitutional, and remanded the case to the lower court to reconsider its earlier invalidation of the full ACA.
On March 2, 2020, the United States Supreme Court granted the petitions for writs of certiorari to review this case, and held oral arguments on November
10, 2020. Pending a decision, the ACA remains in effect, but it is unclear at this time what effect these developments will have on the status of the ACA.

Former  President  Trump  signed  two  Executive  Orders  designed  to  delay  the  implementation  of  certain  provisions  of  the  ACA  or  otherwise  circumvent
some of the requirements for health insurance mandated by the ACA. On January 20, 2017, he signed an Executive Order directing federal agencies with
authorities and responsibilities under the ACA to waive, defer, grant exemptions from, or delay the implementation of any provision of the ACA that would
impose a fiscal burden on states or a cost, fee, tax, penalty or regulatory burden on individuals, healthcare providers, health insurers, or manufacturers of
pharmaceuticals  or  medical  devices.  On  October  13,  2017,  he  signed  an  Executive  Order  terminating  the  cost-sharing  subsidies  that  reimburse  insurers
under the ACA. Several state Attorneys General filed suit to stop the administration from terminating the subsidies, but their request for a restraining order
was

38

denied by a federal judge in California on October 25, 2017. On August 14, 2020, the U.S. Court of Appeals for the Federal Circuit ruled in two separate
cases that the federal government is liable for the full amount of unpaid CSRs for the years preceding and including 2017. For CSR claims made by health
insurance companies for years 2018 and later, further litigation will be required to determine the amounts due, if any. On June 14, 2018, the U.S. Court of
Appeals for the Federal Circuit ruled that the federal government was not required to pay more than $12 billion in ACA risk corridor payments to third-
party payors who argued were owed to them. This decision was appealed to the U.S. Supreme Court, which on April 27, 2020, reversed the U.S. Court of
Appeals for the Federal Circuit's decision and remanded the case to the U.S. Court of Federal Claims, concluding the government has an obligation to pay
these  risk  corridor  payments  under  the  relevant  formula.  To  date,  at  least  $6  billion  has  been  paid  out  to  health  plans  and  insurers,  and  follow-up  class
action and other litigation is pending. The viability of the ACA marketplace and subsequent impacts on providers, and potentially our business, are not yet
known. It is unclear what impact these rulings may have on our business.

The  Bipartisan  Budget  Act  of  2018  also  amended  the  ACA,  effective  January  1,  2019,  by  increasing  the  point-of-sale  discount  that  is  owed  by
pharmaceutical  manufacturers  who  participate  in  Medicare  Part  D  from  50%  to  70%,  effective  January  1,  2019,  and  closing  the  coverage  gap  in  most
Medicare drug plans, commonly referred to as the “donut hole.” On December 20, 2019, former President Trump signed into law the Further Consolidated
Appropriations  Act  (H.R.  1865).  This  law  repeals  the  so  called  “Cadillac”  tax  on  certain  high  cost  employer-sponsored  insurance  plans,  the  annual  fee
imposed on certain health insurance providers based on market share, and the medical device excise tax on non-exempt medical devices. It is impossible to
determine  whether  similar  taxes  could  be  instated  in  the  future.  Additionally,  CMS  published  a  final  rule  that  gives  states  greater  flexibility,  starting  in
2020, in setting benchmarks for insurers in the individual and small group marketplaces, which may have the effect of relaxing the essential health benefits
required under the ACA for plans sold through such marketplaces.

In addition, the Budget Control Act of 2011 and the Bipartisan Budget Act of 2015 led to aggregate reductions of Medicare payments to providers of up to
2% per fiscal year that will remain in effect through 2030 unless additional Congressional action is taken. Pursuant to the Coronavirus Aid, Relief, and
Economic Security Act, also known as the CARES Act, and subsequent legislation, these reductions will be suspended from May 1, 2020 through March
31, 2021 due to the COVID-19 pandemic. As the legislation currently stands, the reductions will go back into effect April 2021 and will remain in effect
through  2030;  however,  proposed  legislation,  if  passed,  would  extend  this  suspension  until  the  end  of  the  pandemic.  Further,  on  January  2,  2013,  the
American  Taxpayer  Relief  Act  was  signed  into  law,  which,  among  other  things,  reduced  Medicare  payments  to  several  types  of  providers,  including
hospitals,  imaging  centers  and  cancer  treatment  centers,  and  increased  the  statute  of  limitations  period  for  the  government  to  recover  overpayments  to
providers from three to five years. More recently, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for
their  marketed  products,  which  has  resulted  in  several  recent  Congressional  inquiries  and  proposed  bills  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  pharmaceutical  products.  Individual  states  in  the  United  States  also  have  become  increasingly  active  in  passing
legislation  and  implementing  regulations  designed  to  control  pharmaceutical  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.

There has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have
been several recent U.S. Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency to
drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform
government program reimbursement methodologies for drugs. The previous administration’s budget proposal for fiscal year 2021 included a $135 billion
allowance to support legislative proposals seeking to reduce drug prices, increase competition, lower out-of-pocket drug costs for patients, and increase
patient access to lower-cost generic and biosimilar drugs. On March 10, 2020, the previous administration sent “principles” for drug pricing to Congress,
calling  for  legislation  that  would,  among  other  things,  cap  Medicare  Part  D  beneficiary  out-of-pocket  pharmacy  expenses,  provide  an  option  to  cap
Medicare  Part  D  beneficiary  monthly  out-of-pocket  expenses,  and  place  limits  on  pharmaceutical  price  increases.  Further,  the  previous  administration
released a “Blueprint” to lower drug prices and reduce out-of-pocket costs of drugs that contains additional proposals to increase manufacturer competition,
increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and reduce the out-
of-pocket costs of drug products paid by consumers. However, it is unclear whether the Biden Administration will challenge, reverse, revoke or otherwise
modify these executive and administrative actions after January 20, 2021.

HHS already has started the process of soliciting feedback on some measures and, at the same time, is immediately implementing others under its existing
authority.  For  example,  in  May  2019,  CMS  issued  a  final  rule  to  allow  Medicare  Advantage  Plans  the  option  of  using  step  therapy  for  Part  B  drugs
beginning January 1, 2020. This final rule codified CMS’s policy change that was effective January 1, 2019. On July 24, 2020 and September 13, 2020,
former  President  Trump  announced  several  executive  orders  related  to  prescription  drug  pricing  that  seek  to  implement  several  of  his  administration's
proposals. The FDA also released a final rule on September 24, 2020, which went into effect on November 30, 2020, creating a process for states to build
and submit to the FDA importation plans for drugs from Canada. Further, on November 20, 2020 CMS issued an Interim Final Rule implementing the Most
Favored Nation ("MFN") Model under which Medicare Part B reimbursement rates will be calculated for certain drugs and biologicals

39

based on the lowest price drug manufacturers receive in Organization for Economic Cooperation and Development countries with a similar gross domestic
product  per  capita.  The  MFN  Model  regulations  mandate  participation  by  identified  Part  B  providers  and  was  intended  to  apply  in  all  U.S.  states  and
territories for a seven-year period beginning January 1, 2021, and ending December 31, 2027. However, on December 28, 2020, a judge in the U.S. District
Court for the Northern District of California granted a preliminary injunction prohibiting CMS from implementing the MFN Model.

On  December  2,  2020,  HHS  published  a  regulation  removing  safe  harbor  protection  for  price  reductions  from  pharmaceutical  manufacturers  to  plan
sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The rule also creates a new safe
harbor for price reductions reflected at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements between pharmacy benefit managers and
manufacturers. Implementation of the amendments to the discount safe harbor has been delayed to January 1, 2023 pending litigation. Although a number
of  these  and  other  proposed  measures  may  require  authorization  through  additional  legislation  to  become  effective,  and  the  Biden  Administration  may
reverse or otherwise change these measures, Congress has indicated that it will continue to seek new legislative measures to control drug costs. At the state
level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical product pricing, including price or
patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some
cases, designed to encourage importation from other countries and bulk purchasing.

Moreover, on May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients to
access certain investigational new drug products that have completed a Phase I clinical trial and that are undergoing investigation for FDA approval. Under
certain  circumstances,  eligible  patients  can  seek  treatment  without  enrolling  in  clinical  trials  and  without  obtaining  FDA  permission  under  the  FDA
expanded access program. There is no obligation for a drug manufacturer to make its drug products available to eligible patients as a result of the Right to
Try  Act  or  FDA’s  expanded  access  program  authorities,  but  the  manufacturer  must  develop  and  make  publicly  available  its  policy  on  expanded  access
availability and respond to patient requests according to that policy.

We expect that additional foreign, federal and state healthcare reform measures will be adopted in the future, any of which could limit the amounts that
federal and state governments will pay for healthcare products and services, which could result in limited coverage and reimbursement and reduced demand
for our products or product candidates, once approved, or additional pricing pressures.

Coverage and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any product candidate for which we obtain regulatory approval. In the United
States and markets in other countries, sales of any product candidates for which we receive regulatory approval for commercial sale will depend, in part, on
the  availability  of  coverage  and  reimbursement  from  third-party  payors.  Third-party  payors  include  government  authorities,  managed  care  providers,
private health insurers and other organizations. The process for determining whether a payor will provide coverage for a product may be separate from the
process  for  setting  the  reimbursement  rate  that  the  payor  will  pay  for  the  product.  Third-party  payors  may  limit  coverage  to  specific  products  on  an
approved list, or formulary, which might not include all of the FDA-approved products for a particular indication. A decision by a third-party payor not to
cover our products or product candidates could reduce physician utilization of our products once approved and have a material adverse effect on our sales,
results  of  operations  and  financial  condition.  Moreover,  a  payor’s  decision  to  provide  coverage  for  a  product  does  not  imply  that  an  adequate
reimbursement rate will be approved. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an
appropriate return on our investment in product development.

In addition, coverage and reimbursement for products can differ significantly from payor to payor. One third-party payor’s decision to cover a particular
pharmaceutical drug product or service does not ensure that other payors will also provide coverage for the pharmaceutical drug product or service or will
provide  coverage  at  an  adequate  reimbursement  rate.  As  a  result,  the  coverage  determination  process  will  require  us  to  provide  scientific  and  clinical
support for the use of our products to each payor separately and will be a time-consuming process.

Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of pharmaceutical drug products and
services, in addition to their safety and efficacy. In order to obtain and maintain coverage and reimbursement for any product, we may need to conduct
expensive clinical trials in order to demonstrate the medical necessity and cost-effectiveness of such product, in addition to the costs required to obtain
regulatory approvals. Our products may not be considered medically necessary or cost-effective. If third-party payors do not consider a product to be cost-
effective compared to other available therapies, they may not cover the product as a benefit under their plans or, if they do, the level of payment may not be
sufficient to allow a company to sell its products at a profit.

The United States government, state legislatures and foreign governments have shown significant interest in implementing cost containment programs to
limit the growth of government-paid healthcare costs, including price controls, restrictions on reimbursement and requirements for substitution of generic
products  for  branded  prescription  drugs.  For  example,  the  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education
Reconciliation Act of 2010 ("ACA") contains provisions that may

40

reduce the profitability of drug products through increased rebates for drugs reimbursed by Medicaid programs, extension of Medicaid rebates to Medicaid
managed care plans, mandatory discounts for certain Medicare Part D beneficiaries and annual fees based on pharmaceutical companies’ share of sales to
federal healthcare programs. Adoption of general controls and measures, coupled with the tightening of restrictive policies in jurisdictions with existing
controls and measures, could limit payments for pharmaceutical drugs.

The  Medicaid  Drug  Rebate  Program  requires  pharmaceutical  manufacturers  to  enter  into  and  have  in  effect  a  national  drug  rebate  agreement  with  the
Secretary of HHS as a condition for state Medicaid coverage of the manufacturer’s outpatient drugs furnished to Medicaid patients. Effective in 2010, the
ACA  made  several  changes  to  the  Medicaid  Drug  Rebate  Program,  including  increasing  pharmaceutical  manufacturers’  rebate  liability  by  raising  the
minimum basic Medicaid rebate on most branded prescription drugs from 15.1% of average manufacturer price ("AMP") to 23.1% of AMP, adding a new
rebate calculation for “line extensions” (i.e., new formulations, such as extended release formulations) of solid oral dosage forms of branded products. In
addition, the ACA also modified the statutory definition of AMP which created a new calculation methodology by which rebates owed by manufacturers
are  determined  for  drugs  that  are  inhaled,  infused,  instilled,  implanted  or  injected  and  thereby  potentially  impacting  manufacturers'  rebate  liability.  The
ACA also expanded the universe of Medicaid utilization subject to drug rebates by requiring pharmaceutical manufacturers to pay rebates on Medicaid
managed care utilization as of 2010 and by expanding the population potentially eligible for Medicaid drug benefits. Pricing and rebate programs also must
comply with the Medicaid rebate requirements of the U.S. Omnibus Budget Reconciliation Act of 1990.

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

For a drug product to receive federal reimbursement under the Medicaid or Medicare Part B programs or to be sold directly to U.S. government agencies,
the manufacturer must extend discounts to entities eligible to participate in the 340B drug pricing program. The required 340B discount on a given product
is  calculated  based  on  the  Medicaid  unit  rebate  amounts  reported  by  the  manufacturer.  As  of  2010,  the  ACA  expanded  the  types  of  entities  eligible  to
receive discounted 340B pricing, although under the current state of the law these newly eligible entities (with the exception of children’s hospitals) will
not be eligible to receive discounted 340B pricing on a drug designated by the Secretary under section 526 of the Federal Food, Drug, and Cosmetic Act for
a  rare  disease  or  condition.  As  340B  drug  pricing  is  determined  based  on  Medicaid  rebate  data,  the  revisions  to  the  Medicaid  rebate  formula  described
above could cause the required 340B discount to increase.

However, on December 27, 2018, the District Court for the District of Columbia invalidated a recent Medicare reimbursement formula change instituted by
CMS when 340B hospitals purchase drugs under the 340B program for use in the hospital outpatient setting. For the 2019 and 2018 fiscal years, CMS
altered the reimbursement formula from Average Sale Price ("ASP") plus 6% to ASP minus 22.5% on specific-covered outpatient drugs. The court ruled
this  change  was  not  an  “adjustment”  which  was  within  the  Secretary’s  discretion  to  make  but  was  instead  a  fundamental  change  in  the  reimbursement
calculation,  and  such  a  dramatic  change  was  beyond  the  scope  of  the  Secretary’s  authority.  On  May  6,  2019,  the  district  court  reiterated  that  the  rate
reduction exceeded the Secretary’s authority and declared that the rate reduction for 2019 also exceeded the Secretary’s authority and remanded the issue to
HHS to devise an appropriate remedy. On July 10, 2019, the district court entered its final judgment and CMS filed an appeal. On July 31, 2020, the U.S.
Court  of  Appeals  for  the  District  of  Columbia  Circuit  overturned  the  district  court’s  decision  and  found  that  the  changes  were  within  the  Secretary’s
authority. On September 14, 2020, the plaintiffs-appellees filed a Petition for Rehearing En Banc (i.e., before the full court); the court denied this Petition
on  October  16,  2020.  It  is  unclear  how  the  invalidation  of  the  formula  could  affect  pharmaceutical  manufacturers  and  hospitals  who  prescribe  their
products, but litigation is still pending on the issue. The American Recovery and Reinvestment Act of 2009 provides funding for the federal government to
compare the effectiveness of different treatments for the same illness. The plan for the research was published in 2012 by HHS, the Agency for Healthcare
Research  and  Quality  and  the  National  Institutes  for  Health,  and  periodic  reports  on  the  status  of  the  research  and  related  expenditures  are  made  to
Congress. Although the results of the comparative effectiveness studies are not intended to mandate coverage policies for public or private payors, it is not
clear what effect, if any, the research will have on the sales of our drugs, if any such drug or the condition that they are intended to treat are the subject of a
trial. It also is possible that comparative effectiveness research demonstrating benefits in a competitor’s drug could adversely affect the sales of our drugs
after approval. If third-party payors do not consider our drugs to be cost-effective compared to other available therapies, they may not cover our drugs after
approval as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow us to sell our drugs on a profitable basis. On
November 20, 2020, the HHS

41

Office of Inspector General finalized its 2019 proposal to exclude certain rebates paid by drug manufacturers from the discount safe harbor of the federal
anti-kickback statute. The final rule is entitled “Fraud and Abuse; Removal of Safe Harbor Protection for Rebates Involving Prescription Pharmaceuticals
and Creation of New Safe Harbor Protection for Certain Point-of-Sale Reductions in Price on Prescription Pharmaceuticals and Certain Pharmacy Benefit
Manager Service Fees”. Under the final rule, discount safe harbor protection for Part D rebates is eliminated. The rule establishes a new safe harbor for
point-of-sale price reductions and establishes a new safe harbor for pharmacy benefit manager service fees.

These  laws  and  future  state  and  federal  healthcare  reform  measures  may  be  adopted  in  the  future,  any  of  which  may  result  in  additional  reductions  in
Medicare  and  other  healthcare  funding  and  otherwise  affect  the  prices  we  may  obtain  for  any  of  our  products  or  product  candidates  for  which  we  may
obtain regulatory approval or the frequency with which any such product is prescribed or used.

As noted above, the marketability of any products for which we receive regulatory approval for commercial sale may suffer if the government and third-
party  payors  fail  to  provide  adequate  coverage  and  reimbursement.  We  expect  that  an  increasing  emphasis  on  cost  containment  measures  in  the  United
States will continue to increase the pressure on pharmaceutical pricing. 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 of our products or product candidates for which we receive regulatory
approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Further, there have been several recent U.S. congressional inquiries, proposed federal legislation, and proposed and enacted state legislation designed to,
among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the costs
of  drugs  under  Medicare  and  reform  government  program  reimbursement  methodologies  for  drug  products.  At  the  federal  level,  Congress  and  the
Executive Office of the President of the United States have each indicated that it will continue to pursue new legislative and/or administrative measures to
control  drug  costs.  Individual  state  legislatures  have  become  increasingly  aggressive  in  passing  legislation  and  implementing  regulations  designed  to
control pharmaceutical and biological product pricing. Some of these measures include price or patient reimbursement constraints, discounts, restrictions
on  certain  product  access,  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  measures  designed  to  encourage  importation  from
other  countries  and  bulk  purchasing.  In  addition,  regional  healthcare  authorities  and  individual  hospitals  are  increasingly  using  bidding  procedures  to
determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. These measures
could reduce the ultimate demand for our products or product candidates, once approved, or put pressure on our product pricing. For example, on October
1, 2020, the FDA published a final rule that allows for the importation of certain prescription drugs from Canada. Under the final rule, States and Native
American Tribes, and in certain future circumstances pharmacists and wholesalers, may submit importation program proposals to the FDA for review and
authorization. Since the issuance of the final rule, several industry groups have filed federal lawsuits challenging multiple aspects of the final rule, and
authorities  in  Canada  have  passed  rules  designed  to  safeguard  the  Canadian  drug  supply  from  shortages.  On  September  25,  2020,  CMS  stated  drugs
imported by States under this rule will not be eligible for federal rebates under Section 1927 of the Social Security Act and manufacturers would not report
these drugs for “best price” or Average Manufacturer Price purposes. Since these drugs are not considered covered outpatient drugs, CMS further stated it
will not publish a National Average Drug Acquisition Cost for these drugs. Separately, the FDA also issued a final guidance document outlining a pathway
for manufacturers to obtain an additional National Drug Code ("NDC") for an FDA-approved drug that was originally intended to be marketed in a foreign
country and that was authorized for sale in that foreign country. Since the issuance of the final rule, on November 23, 2020, several industry groups filed
federal lawsuits in the U.S. District Court for the District of Columbia, requesting injunctive relief to prevent certification from the Secretary of HHS from
taking effect and challenging multiple aspects of the final rule. This litigation has not progressed. The market implications of the final rule and guidance are
unknown  at  this  time.  Proponents  of  drug  reimportation  may  attempt  to  pass  legislation  that  would  directly  allow  reimportation  under  certain
circumstances. Legislation  or  regulations  allowing  the  reimportation  of  drugs,  if  enacted  and  implemented,  could  decrease  the  price  we  receive  for  any
products that we may develop and adversely affect our future revenues and prospects for profitability.

Outside the United States, the pricing of pharmaceutical products and medical devices is subject to governmental control in many countries. For example,
in the EU, pricing and reimbursement schemes vary widely from country to country. Some countries provide that products may be marketed only after a
reimbursement price has been agreed. Some countries may require the completion of additional studies that compare the cost-effectiveness of a particular
therapy to currently available therapies or so-called health technology assessments, in order to obtain reimbursement or pricing approval. Other countries
may allow companies to fix their own prices for products but monitor and control product volumes and issue guidance to physicians to limit prescriptions.
Efforts  to  control  prices  and  utilization  of  pharmaceutical  products  and  medical  devices  likely  will  continue  as  countries  attempt  to  manage  healthcare
expenditures.

Human Capital Management

As of December 31, 2020, we had 180 full-time employees in the United States, 76 of whom were primarily engaged in sales and marketing, 70 of whom
were primarily engaged in administration and finance, and 34 of whom were primarily engaged in product development and research.

We  believe  our  success  will  depend  on,  among  other  things,  our  ability  to  continue  to  hire  and  retain  the  necessary  qualified  scientific,  technical,  and
managerial  personnel,  as  we  expand  the  commercialization  of  Gvoke  and  continue  development  of  our  product  candidates.  Our  President  and  Chief
Operating Officer and Executive Director, Human Resources are responsible for developing and executing our human capital strategy. This includes the
attraction, acquisition, development and engagement of talent to deliver on the Company’s strategy and the design of employee compensation and benefits
programs. In addition, the Chief Executive Officer and President and Chief Operating Officer regularly update our board of directors and its committees on
the operation and status of these human capital trends and activities.

Employee health and safety in the workplace is one of our core values. The COVID-19 pandemic has underscored for us the importance of keeping our
employees  safe  and  healthy.  Refer  to  "Impact  of  COVID-19"  included  in  Item  7,  "Management’s  Discussion  and  Analysis  of  Financial  Condition  and

ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk. Careful consideration should be given to the following risk factors, in addition to the other
information set forth in this Annual Report for the year ended December 31, 2020 and in other documents that we file with the SEC, in evaluating us and
our business. If any of the following risks and uncertainties actually occurs, our business, prospects, financial condition and results of operations could be
materially and adversely affected. The risks summarized and described below are not intended to be exhaustive and are not the only risks facing us. New
risk factors can emerge from time to time, and it is not possible to predict the impact that any factor or combination of factors may have on our business,
prospects, financial condition and results of operations.

Risks Related to the Impact of the COVID-19 Coronavirus

Our business may be adversely affected by the ongoing coronavirus pandemic.

Our business could be adversely affected by health epidemics in regions where we have business activities and could cause significant disruption in the
operations  of  third-party  manufacturers  and  contract  research  organizations  ("CROs")  upon  whom  we  rely,  and  for  which  we  may  not  have  adequate
insurance coverage. For example, beginning in late 2019, the outbreak of a novel strain of virus named SARS-CoV-2 (severe acute respiratory syndrome
coronavirus 2), or coronavirus, which causes coronavirus disease 2019, or COVID-19, has evolved into a global pandemic. The coronavirus has spread to
most regions of the world.

As  a  result  of  the  coronavirus  pandemic,  we  may  experience  disruptions  that  could  severely  impact  our  business,  preclinical  studies  and  clinical  trials,
including:

We  believe  that  the  COVID-19  pandemic  has  had,  and  may  continue  to  have,  an  adverse  impact  on  demand  for  our  product,  Gvoke,  due  to
government-imposed quarantines, stay-at-home orders, travel restrictions, mandated business closures and other public health safety measures
which may result in patients not visiting their healthcare providers or their pharmacies to get their prescriptions filled. Initially, we suspended
in-person interactions by our sales and marketing personnel in healthcare settings. We are engaging with these customers remotely, via webinar
programs and virtual meetings, as we seek to continue to support healthcare professionals and patient care. As parts of the country reopened,
some of our sales and marketing personnel began to reengage with a limited number of in-person interactions. However, with the resurgence of
COVID-19 in many areas, our ability to connect with our customers in person became much more limited and we are currently back to almost
exclusively  remote  interactions.  In  addition,  several  conferences  and  other  programs  at  which  we  intended  to  market  Gvoke  have  been
postponed, canceled and/or transitioned to virtual meetings. Remote interactions may be less effective than in-person interactions. In addition,
due to the prioritization of healthcare resources toward pandemic efforts, even remote interactions may not be possible.
We currently rely on third-party suppliers and contract manufacturing organizations for the manufacture of Gvoke as well as to perform third-
party logistics functions, including warehousing and distribution of Gvoke. In addition, we rely on third parties to perform quality testing and
supply  other  goods  and  services  to  run  our  business.  If  any  such  third  party  in  our  supply  chain  for  materials  is  adversely  impacted  by
restrictions resulting from the COVID-19 pandemic, including staffing shortages, production slowdowns and disruptions in delivery systems,
our supply chain may be disrupted, limiting our ability to manufacture commercial quantities of Gvoke.
In March 2020, we closed our offices and requested that most of our personnel, including all of our administrative employees, work remotely,
restricted on-site staff to only those personnel and contractors who must perform essential activities that must be completed on-site and limited
the number of staff in any given location. We reopened our offices in mid-June on a limited, voluntary basis for those personnel who prefer to
work  from  the  office.  Our  increased  reliance  on  personnel  working  from  home  may  negatively  impact  productivity,  or  disrupt,  delay,  or
otherwise adversely impact our business. Further, this could increase our cyber-security risk, create data accessibility concerns, and make us
more susceptible to communication disruptions, any of which could adversely impact our business operations or delay necessary interactions
with  local  and  federal  regulators,  ethics  committees,  manufacturing  sites,  research  or  clinical  trial  sites  and  other  important  agencies  and
contractors. In addition, we have implemented certain measures to reduce spending and have delayed or suspended projects. Although we have
implemented such cost reducing measures, we may not realize, in full or in part, the anticipated benefits, savings and improvements in our cost
structure from such measures due to unforeseen difficulties, delays or unexpected costs. If we are unable to realize the expected cost savings
from such measures, our operating results and financial condition would be adversely affected.
Although  essential  personnel  in  our  laboratory  currently  remain  on-site,  they  and  other  employees  and  contractors  conducting  research  and
development activities on our behalf may not be able to access our laboratory or conduct such activities for an extended period of time in the
event of the closure of our offices or the offices of our contractors and/or the possibility that governmental authorities further modify current
restrictions. As a result, this could delay timely completion of preclinical activities.

We have previously and may in the future conduct clinical trials for product candidates in geographies which are affected by the coronavirus
pandemic. Potential impacts of the coronavirus pandemic on our various clinical trials may include disruptions or delays in patient enrollment,
standard study monitoring practices, sample shipments, data analysis and reporting of results due to changes in policies at various clinical sites
or  in  federal,  state,  local  or  foreign  laws,  rules  and  regulations.  Other  impacts  could  include  quarantines  or  other  travel  restrictions  and
prioritization  of  healthcare  resources  toward  pandemic  efforts,  including  diminished  attention  of  physicians  serving  as  our  clinical  trial
investigators and reduced availability of site staff supporting the conduct of our clinical trials. Interruption or delays in the operations of the
FDA could also impair our ability to discuss ongoing or future clinical programs. If the coronavirus pandemic continues, other aspects of our
clinical trials could be adversely affected, delayed or interrupted, including, for example, site initiation, patient recruitment and enrollment, and
availability of clinical trial materials. It is unknown how long these pauses or disruptions could continue.
Health  regulatory  agencies  globally  may  experience  disruptions  in  their  operations  as  a  result  of  the  coronavirus  pandemic.  The  FDA  and
comparable foreign regulatory agencies may have slower response times or be under-resourced to continue to monitor our clinical trials and, as
a result, review, inspection, and other timelines may be materially delayed. It is unknown how long these disruptions could continue, were they
to occur. Any elongation or de-prioritization of our clinical trials or delay in regulatory review resulting from such disruptions could materially
affect the development and study of our product candidates. For example, regulatory authorities may require that we not distribute a product
candidate lot until the relevant agency authorizes its release. Such release authorization may be delayed as a result of the coronavirus pandemic
and could result in delays to our clinical trials.
The  trading  prices  for  our  common  shares  and  other  biopharmaceutical  companies  have  been  highly  volatile  as  a  result  of  the  coronavirus
pandemic. As a result, we may face difficulties raising further capital through sales of our common shares or convertible debt or such sales may
be  on  unfavorable  terms.  In  addition,  a  recession,  depression  or  other  sustained  adverse  market  event  resulting  from  the  spread  of  the
coronavirus could materially and adversely affect our business and the value of our common shares.

To  date,  three  vaccines  for  COVID-19  were  granted  Emergency  Use  Authorization  by  the  FDA.  The  resultant  demand  for  vaccines  and  potential  for
manufacturing facilities and materials to be commandeered under the Defense Production Act of 1950, or equivalent foreign legislation, may make it more
difficult to obtain materials or manufacturing slots for the products needed for our clinical trials and/or commercial product, which could lead to delays in
these trials and/or issues with our commercial supply.

The coronavirus pandemic continues to rapidly evolve. The ultimate impact of the coronavirus pandemic on our business operations is highly uncertain and
subject  to  change  and  will  depend  on  future  developments,  which  cannot  be  accurately  predicted,  including  the  duration  of  the  pandemic,  the  ultimate
geographic  spread  of  the  disease,  additional  or  modified  government  actions,  new  information  that  will  emerge  concerning  the  severity  and  impact  of
COVID-19 and the actions taken to contain coronavirus or address its impact in the short and long term, among others. We do not yet know the full extent
of potential delays or impacts on our business, our clinical trials, our research programs, healthcare systems or the global economy. We will continue to
monitor the situation closely.

Risks Related to our Financial Position and Need for Financing

Risks Related to Our Operating History

As  a  company,  we  have  a  limited  operating  history  and  limited  experience  commercializing  pharmaceutical  products  and  have  incurred  significant
losses since inception. We expect to incur losses over the next several years and may not be able to achieve or sustain revenues or profitability in the
future.

Historically,  we  have  funded  our  operations  primarily  through  private  placements  of  convertible  preferred  stock,  public  offerings  of  common  stock  and
convertible notes, and issuance of debt. We commercially launched Gvoke PFS in November 2019 and Gvoke HypoPen in July 2020. We are in the early
stages  of  commercializing  our  first  pharmaceutical  product  and  have  a  limited  operating  history.  Pharmaceutical  product  development  is  a  highly
speculative undertaking and involves a substantial degree of risk. Accordingly, you should consider our prospects in light of the costs, uncertainties, delays
and  difficulties  frequently  encountered  by  companies  prior  to  and  at  the  early  stages  of  commercialization  of  any  product  candidates,  especially
pharmaceutical companies such as ours. Any predictions you make about our future success or viability may not be as accurate as they could be if we had a
longer  operating  history  or  a  history  of  successfully  commercializing  pharmaceutical  products.  We  may  encounter  unforeseen  expenses,  difficulties,
complications, delays and other known or unknown factors in achieving our business objectives. We will need to successfully complete the transition from
a company with a development focus to a company capable of supporting commercial activities. We may not be successful in such a transition. We expect
our financial condition and operating results to continue to fluctuate significantly from quarter to quarter and year to year due to a variety of factors, many
of which are beyond our control. Accordingly, you should not rely upon the results of any quarterly or annual periods as indications of future operating
performance.

45

We have incurred significant losses in every fiscal year since inception. For the years ended December 31, 2020 and 2019, we reported a net loss of $91.1
million  and  $125.6  million,  respectively.  In  addition,  our  accumulated  deficit  as  of  December  31,  2020  was  $337.4  million.  Substantially  all  of  our
operating losses have resulted from costs incurred in connection with research and development, clinical and regulatory initiatives to obtain approvals for
our product candidates and preparation for commercialization of Gvoke and more recently the commercial launch of Gvoke.

We expect to continue to incur significant operating expenses as we continue the commercialization of Gvoke, develop, enhance and commercialize new
products and incur additional operational and reporting costs associated with being a public company. In particular, we anticipate that we will continue to
incur significant expenses as we:

execute our Gvoke commercial strategy in the U.S. and our Ogluo commercial strategy outside the U.S.;

<
<   continue our research and development efforts;
<
<

seek regulatory approval for new product candidates and product enhancements; and
continue to operate as a public company.

Our first product, Gvoke, was approved by the FDA for the treatment of severe hypoglycemia in pediatric and adult patients with diabetes ages two years
and above on September 10, 2019. On February 11, 2021 the European Commission ("EC") granted a marketing authorization for Ogluo for the treatment
of  severe  hypoglycemia  in  adults,  adolescents,  and  children  aged  two  years  and  over  with  diabetes  mellitus.  We  currently  plan  to  commercially  launch
Ogluo in select European countries beginning in the fourth quarter of 2021. Our ability to generate revenue from Gvoke, Ogluo and our product candidates
and to transition to profitability and generate positive cash flows is uncertain and depends on the successful commercialization of Gvoke and our product
candidates.  Many  of  our  product  candidates  are  still  in  development.  Successful  development  and  commercialization  will  require  achievement  of  key
milestones, including completing clinical trials and obtaining marketing approval for our product candidates, manufacturing, marketing and selling those
products  for  which  we,  or  any  of  our  future  collaborators,  may  obtain  marketing  approval,  satisfying  any  post-marketing  requirements  and  obtaining
reimbursement for our products from private insurance or government payors. Because of the uncertainties and risks associated with these activities, we are
unable to accurately predict the timing and amount of revenues, and if or when we might achieve profitability. We and any future collaborators may never
succeed  in  these  activities  and,  even  if  we  or  any  future  collaborators  do,  we  may  never  generate  revenues  that  are  large  enough  for  us  to  achieve
profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis.

Our failure to become and remain profitable would depress the market price of our common stock and could impair our ability to raise capital, expand our
business, diversify our product offerings or continue our operations. If we continue to suffer losses as we have in the past, investors may not receive any
return on their investment and may lose their entire investment.

Although we generate revenue from Gvoke PFS and Gvoke HypoPen, we have not yet generated revenue from any of our current or future product
candidates and may never be profitable.

Our ability to become profitable depends upon our ability to generate revenue. Our ability to generate revenue depends on a number of factors, including,
but not limited to, our ability to:

<

<

<

<

<

obtain commercial quantities of Gvoke at acceptable cost levels;
achieve an adequate level of market acceptance of our products in the medical community and with third-party payors, including placement in
accepted clinical guidelines for the conditions for which our product candidates are intended to target;
obtain and maintain third-party coverage and adequate reimbursement for our products;
launch and commercialize our products utilizing our own sales force or by entering into partnership or co-promotion arrangements with third
parties; and
successfully develop and obtain marketing approval for our product candidates.

We  have  incurred  and  expect  to  continue  to  incur  significant  sales  and  marketing  costs  as  we  commercialize  Gvoke.  Regardless  of  these  expenditures,
Gvoke  and  our  product  candidates,  if  approved,  may  not  be  commercially  successful.  Although  we  generate  revenue  from  Gvoke  PFS  and  Gvoke
HypoPen,  if  we  are  unable  to  generate  sufficient  product  revenue,  we  will  not  become  profitable  and  may  be  unable  to  continue  operations  without
continued funding.

46

 
Risks Related to Future Financial Condition

We may require additional capital to sustain our business, and this capital may cause dilution to our stockholders and might not be available on terms
favorable to us, or at all, which would force us to delay, reduce or eliminate our product development programs or commercialization efforts.

Pharmaceutical  development  is  a  time  consuming,  expensive  and  uncertain  process  that  takes  years  to  complete.  We  are  incurring  significant
commercialization expenses related to product sales, marketing, manufacturing, packaging and distribution of Gvoke and expect to continue to incur such
expenses  for  Gvoke  as  well  as  for  any  of  our  product  candidates,  if  approved.  Accordingly,  we  may  need  to  obtain  substantial  additional  funding  in
connection with our continuing operations. For example, due to the impacts of the COVID-19 pandemic on our business, including those discussed in the
risk factor titled “Our business may be adversely affected by the ongoing coronavirus pandemic,” we applied for and received a PPP Loan on April 22,
2020 for $5.1 million, of which $0.9 million was repaid on May 4, 2020 and the remaining $4.2 million on June 30, 2020. While we initiated a variety of
cost reduction initiatives, we sought and obtained the PPP Loan due to our belief that such funds were necessary to support payroll costs, rent and utilities
in order to avoid more drastic measures, such as deep workforce reductions, that would have likely significantly impaired our financial viability. In the
future, if we are unable to raise capital when needed or on attractive terms, we may be forced to delay, reduce or eliminate our research and development
programs. We will be required to expend significant funds in order to commercialize Gvoke as well as any of our product candidates that receive marketing
approval.

We  may  be  required  to  or  choose  to  obtain  further  funding  through  public  equity  offerings,  debt  financings,  royalty-based  financing  arrangements,
collaborations and licensing arrangements or other sources. If we raise additional funds through further issuances of equity or convertible debt securities,
our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to
those of holders of our common stock. Any debt financing obtained by us would be senior to our common stock, would likely cause us to incur interest
expense, and could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may increase
our expenses and make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions and in-
licensing opportunities. Under our existing credit facility, the Amended and Restated Loan and Security Agreement dated September 10, 2019 (as amended,
supplemented  or  otherwise  modified  from  time  to  time,  including  by  that  certain  First  Amendment  to  the  Amended  and  Restated  Loan  and  Security
Agreement dated April 21, 2020, that certain Second Amendment to the Amended and Restated Loan and Security Agreement dated June 30, 2020, that
certain Third Amendment to the Amended and Restated Loan and Security Agreement dated August 5, 2020 and that certain the Fourth Amendment to the
Amended and Restated Loan and Security Agreement dated October 23, 2020, collectively, the “Amended Loan Agreement”) with Oxford Finance LLC, as
the collateral agent and a lender, and Silicon Valley Bank, as a lender, and the Company, we are restricted in our ability to incur additional indebtedness and
to pay dividends but, in connection with our public notes offering, the Lenders consented to the Convertible Notes (defined below) offering as permitted
convertible indebtedness. Any additional debt financing that we may secure in the future could include similar or more restrictive covenants relating to our
capital raising activities, buying or selling assets and other financial and operational matters, which may make it more difficult for us to obtain additional
capital, manage our business and pursue business opportunities. We may also be required to secure any such debt obligations with some or all of our assets.
For example, our Amended Loan Agreement is secured by substantially all of our property and assets, including our intellectual property assets, subject to
certain exceptions.

If we raise additional funds through collaborations or marketing, distribution or licensing, or royalty-based financing arrangements with third parties, we
may  have  to  relinquish  valuable  rights  to  our  technologies,  future  revenue  streams  or  product  candidates  or  grant  licenses  on  terms  that  may  not  be
favorable  to  us.  Securing  financing  could  require  a  substantial  amount  of  time  and  attention  from  our  management  and  may  divert  a  disproportionate
amount of their attention away from day-to-day activities, which may adversely affect our management’s ability to oversee the commercialization of Gvoke
and  development  and  commercialization,  if  approved,  of  our  product  candidates.  It  is  also  possible  that  we  may  allocate  significant  amounts  of  capital
toward solutions or technologies for which market demand is lower than anticipated and, as a result, abandon such efforts. Adequate additional financing
may not be available to us on acceptable terms, or at all. Market volatility resulting from the COVID-19 pandemic or other factors could also adversely
impact our ability to access capital as and when needed. If we are unable to raise additional funds when needed, we may be required to delay, limit, reduce
or  terminate  our  product  development  or  grant  rights  to  develop  and  market  product  candidates  that  we  would  otherwise  prefer  to  develop  and  market
ourselves. Any of these negative developments could have a material adverse effect on our business, operating results, financial condition and common
stock price.

We may not have cash available to us in an amount sufficient to enable us to make interest or principal payments on our indebtedness when due.

On  June  30,  2020,  we  completed  a  public  offering  of  $86.3  million  aggregate  principal  amount  of  our  5.00%  Convertible  Senior  Notes  due  2025  (the
"Convertible Notes"), including $11.3 million pursuant to the underwriters' option to purchase additional notes which was exercised in July 2020. A total
principal amount of $39.1 million of Convertible Notes converted into equity in the second half of 2020. As of December 31, 2020, the outstanding balance
of Convertible Notes was $47.2 million. The Convertible Notes are governed

47

by  the  terms  of  a  base  indenture  for  senior  debt  securities  (the  “Base  Indenture”),  as  supplemented  by  the  first  supplemental  indenture  thereto  (the
“Supplemental  Indenture”  and  together  with  the  Base  Indenture,  the  “Indenture”),  each  dated  as  of  June  30,  2020,  between  us  and  U.S.  Bank  National
Association, as trustee. Failure to satisfy our current and future debt obligations under the Indenture could result in an event of default and, as a result, all of
the amounts outstanding could immediately become due and payable. In the event of an acceleration of amounts due under the Indenture as a result of an
event of default, we may not have sufficient funds or may be unable to arrange for additional financing to repay our indebtedness while still pursuing our
current business strategy.

In addition, we have $43.5 million outstanding under our Amended Loan Agreement as of December 31, 2020. All obligations under our Amended Loan
Agreement are secured by substantially all of our property and assets, including our intellectual property assets, subject to certain limited exceptions. The
term loans and the Convertible Notes may create additional financial risk for us, particularly if our business or prevailing financial market conditions are
not conducive to paying off or refinancing our outstanding debt obligations at maturity. Failure to satisfy our current and future debt obligations under our
Amended Loan Agreement could result in an event of default and, as a result, our lenders could accelerate all amounts due. Events of default also include
our failure to comply with customary affirmative and negative covenants as well as a default under any indenture or other agreement governing convertible
indebtedness  permitted  by  the  Amended  Loan  Agreement,  including  the  Indenture.  Affirmative  covenants  include  the  maintenance  of  a  minimum  cash
balance of $5.0 million in an account with Silicon Valley Bank and, in the event that we also maintain one or more permitted accounts at other institutions,
an additional amount equal to the outstanding obligations. Negative covenants include prohibition on the payment of dividends and distributions, certain
mergers and change of control events, and restrictions on the incurrence of additional debt. In addition, the occurrence of material adverse changes in the
company’s business, including its prospect of repayment of its obligations, could result in an event of default. In the event of an acceleration of amounts
due under our Amended Loan Agreement as a result of an event of default, we may not have sufficient funds or may be unable to arrange for additional
financing to repay our indebtedness while still pursuing our current business strategy. In addition, our lenders could seek to enforce their security interests
in any collateral securing such indebtedness.

We may be unable to raise the funds necessary to repurchase the Convertible Notes for cash following a fundamental change, and our existing and
future indebtedness may limit our ability to repurchase the Convertible Notes.

Noteholders  may  require  us  to  repurchase  their  Convertible  Notes  following  a  fundamental  change  at  a  cash  repurchase  price  generally  equal  to  the
principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest, if any. A fundamental change includes certain acquisition
transactions and the failure of our common stock to be listed on the Nasdaq Global Select Market or certain similar national securities exchanges. We may
not have enough available cash or be able to obtain financing at the time we are required to repurchase the Convertible Notes. In addition, applicable law,
regulatory authorities and the agreements governing our existing and future indebtedness may restrict our ability to repurchase the Convertible Notes. Our
failure to repurchase the Convertible Notes when required will constitute a default under the Indenture that governs the Convertible Notes. A default under
the Indenture or the fundamental change itself could also lead to a default under agreements governing our future indebtedness, which may result in that
other  indebtedness  becoming  immediately  payable  in  full.  A  fundamental  change  would  constitute  an  event  of  default  under  our  Amended  Loan
Agreement. We may not have sufficient funds to satisfy all amounts due under the other indebtedness and the Convertible Notes.

Our PPP Loan, which we repaid in full in June 2020, was subject to the terms and conditions applicable to loans administered by the SBA under the
CARES Act, and we may be subject to an audit or enforcement action related to the PPP Loan.

On April 21, 2020, we entered into the U.S. Small Business Administration (the "SBA") Paycheck Protection Program (the "PPP") Note (the "Note") with
Silicon Valley Bank (the “PPP Lender”) for a loan in the amount of $5.1 million (the “PPP Loan”) enabled by the Coronavirus Aid, Relief and Economic
Security Act of 2020 (the "CARES Act"). We received the full amount of the PPP Loan on April 22, 2020. On May 4, 2020, we repaid $0.9 million of the
PPP Loan. In June 2020, we repaid the remaining amount outstanding under the PPP loan in connection with the concurrent Convertible Notes and equity
offerings.

We  may  be  subject  to  CARES  Act-specific  lookbacks  and  audits  that  may  be  conducted  by  other  federal  agencies,  including  several  oversight  bodies
created under the CARES Act. These bodies have the ability to coordinate investigations and audits and refer matters to the Department of Justice for civil
or criminal enforcement and other actions. Complying with such SBA audit could divert management resources and attention and require us to expend
significant time and resources, which could have an adverse effect on our business, financial condition and results of operations.

Risks Related to the Commercialization and Marketing of our Products and Product Candidates

Risks Related to Commercialization and Marketing

Our business depends entirely on the success of our products and product candidates. Even if approved, our product candidates may not be accepted in
the marketplace and our business may be materially harmed.

To date, we have expended significant time, resources and effort on the development of our product candidates, and a substantial portion of our resources
recently has been and will continue to be focused on launching, marketing and commercializing our first product, Gvoke, in the United States. Our business
and future success are substantially dependent on our ability to generate product revenues in the near term and will depend on our ability to successfully
commercialize Gvoke. Our product candidates are in earlier stages of development and subject to the risks of failure inherent in developing drug products.
Any delay or setback in the regulatory approval, product launch, commercialization or distribution of any of our product candidates will adversely affect
our business. We may not be able to successfully launch or commercialize our products or meet our expectations with respect to revenues. We began to
commercially launch our first pharmaceutical product, Gvoke PFS, in November 2019, and commercially launched Gvoke HypoPen in July 2020. There is
no  guarantee  that  the  infrastructure,  systems,  processes,  policies,  relationships  and  materials  we  have  built  for  the  commercialization  of  Gvoke  will  be
sufficient for us to achieve success at the levels we expect. Further, our products may contain undetected manufacturing defects, including mislabeling,
which might require product replacement, re-labeling or product recalls, which could further harm our business.

Even  if  all  regulatory  approvals  are  obtained,  the  commercial  success  of  our  products  and  product  candidates,  if  approved,  depends  on  gaining  market
acceptance among physicians, patients, patient advocacy groups, healthcare payors and the medical community. The degree of market acceptance of our
products and product candidates will depend on many factors, including:

<

<

<

<

<

<

<

<

<

<

<

<

<

  the scope of regulatory approvals, including limitations or warnings contained in a product's regulatory-approved labeling;

our ability to produce, through a validated process, sufficiently large quantities of our products to permit successful commercialization;
our ability to establish and maintain commercial manufacturing arrangements with third-party manufacturers;
our ability to build and maintain sales, distribution and marketing capabilities sufficient to launch commercial sales of our products;
the acceptance in the medical community of the potential advantages of the products, including with respect to our efforts to increase adoption
of our products by patients and healthcare providers;
the incidence, prevalence and severity of adverse side effects of our products;
the willingness of physicians to prescribe our products and of the target patient population to try these therapies;
the price and cost-effectiveness of our products;
the  availability  of  sufficient  third-party  coverage  and  reimbursement,  including  the  extent  to  which  each  product  is  approved  for  use  at,  or
included on formularies of, hospitals and managed care organizations;
any negative publicity related to our or our competitors’ products or other formulations of products that we administer, including as a result of
any related adverse side effects;
alternative treatment methods and potentially competitive products;
the potential advantages of our products over existing and future treatment methods; and
the strength of our sales, marketing and distribution support.

Additionally, if, after marketing approval of any of our products or product candidates, we or others later identify undesirable or unacceptable side effects
caused by such products, a number of potentially significant negative consequences could result, including:

<

<

<

<

  regulatory authorities may withdraw approvals of such product, require us to take our approved product off the market or ask us to voluntarily

remove the product from the market;
regulatory  authorities  may  require  the  addition  of  labeling  statements,  specific  warnings,  a  contraindication  or  field  alerts  to  physicians  and
pharmacies;
regulatory authorities may impose conditions under a risk evaluation and mitigation strategy ("REMS") including distribution of a medication
guide to patients outlining the risks of such side effects or imposing distribution or use restrictions;
we may be required to change the way the product is administered, conduct additional clinical trials or change the labeling of the product;

49

<

<

<

<

we may be subject to limitations on how we may promote the product;
sales of the product may decrease significantly;
we may be subject to litigation or product liability claims; and
our reputation may suffer.

If our product candidates are approved but do not achieve an adequate level of acceptance by physicians, patients and third-party payors, we may never
generate significant revenue from these products, and our business, financial condition and results of operations may be materially harmed. Even if our
products achieve market acceptance, we may not be able to maintain that market acceptance over time if new therapeutics are introduced that are more
favorably received than our products or that render our products obsolete, or if significant adverse events occur. If our products do not achieve and maintain
market acceptance, we will not be able to generate sufficient revenue from product sales to attain profitability.

The market opportunity for Gvoke and our product candidates may be smaller than we estimate.

The potential market opportunity for Gvoke and our product candidates is difficult to precisely estimate. Our estimates of the potential market opportunity
for Gvoke and our product candidates include several key assumptions of the current market size and current pricing for commercially available products
and  are  based  on  industry  and  market  data  obtained  from  industry  publications,  studies  conducted  by  us,  our  industry  knowledge,  third-party  research
reports and other surveys. Industry publications and third-party research generally indicate that their information has been obtained from sources believed
to be reliable, although they do not guarantee the accuracy or completeness of such information. For example, our projections for the potential size of the
market for Gvoke are based on our belief that we would be able to increase the adoption of emergency glucagon products by patients and care providers.
While we believe that our internal assumptions are reasonable, if any of these assumptions proves to be inaccurate, the actual market for our product and
product candidates could be smaller than our estimates of our potential market opportunity. If the actual market for Gvoke and our product candidates is
smaller than we expect, our product revenue may be limited and it may be more difficult for us to achieve or maintain profitability.

Our  company  has  limited  experience  marketing  and  selling  drug  products  and  has  recently  developed  our  sales  organization.  If  we  are  unable  to
establish  or  do  not  maintain  sufficient  marketing,  sales  and  distribution  capabilities  or  enter  into  agreements  with  third  parties  to  market,  sell  and
distribute  our  products  on  terms  acceptable  to  us,  we  may  not  be  able  to  generate  product  revenues  and  our  business,  results  of  operations,  and
financial condition will be materially adversely affected.

We  have  recently  developed  our  commercial  infrastructure  for  the  sales,  marketing  and  distribution  of  Gvoke.  In  order  to  successfully  commercialize
Gvoke and our product candidates, we will need to maintain and may need to expand our marketing, sales, distribution, managerial and other non-technical
capabilities  and/or  make  arrangements  with  third  parties  to  perform  some  or  all  of  these  services.  We  have  recently  established  a  sales  force  to  market
Gvoke in the United States. There are significant expenses and risks involved with establishing our own sales and marketing capabilities, including our
ability to hire, retain and appropriately incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing
personnel,  and  effectively  manage  a  geographically  dispersed  sales  and  marketing  team.  Any  failure  or  delay  in  our  ability  to  maintain  or  expand,  if
needed, our internal sales, marketing and distribution capabilities could delay or limit the success of any product launch, which would adversely impact the
commercialization of our products, including Gvoke.

We cannot be sure that we will be able to recruit, hire and retain a sufficient number of sales representatives or that they will be effective at promoting our
products. In addition, we will need to commit significant additional management and other resources to establish and grow our sales organization. We may
not be able to achieve the necessary development and growth in a cost-effective manner or realize a positive return on our investment. We will also have to
compete with other companies to recruit, hire, train and retain sales and marketing personnel.

Factors that may inhibit our efforts to commercialize our products include:

  <
<

<

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

the inability of sales personnel to obtain access to or to persuade adequate numbers of physicians to prescribe any of our product candidates that
receive regulatory approval; and
unforeseen costs and expenses associated with maintaining an independent sales and marketing organization.

In  the  event  that  we  are  unable  to  effectively  deploy  our  sales  organization  or  distribution  strategy  on  a  timely  and  efficient  basis,  if  at  all,  the
commercialization of our product candidates could be delayed which would negatively impact our ability to generate product revenues. For example, as a
result of the COVID-19 pandemic, we have had to limit in-person interactions and engage with many

healthcare professionals remotely, which may be less effective. In addition, due to the prioritization of healthcare resources toward pandemic efforts, even
remote interactions may not be possible.

We  intend  to  leverage  the  sales  and  marketing  capabilities  that  we  are  establishing  for  Gvoke  to  commercialize  additional  product  candidates  for  the
management of other hypoglycemic conditions, if approved by the FDA, in the United States. If we are unable to do so for any reason, we would need to
expend additional resources to establish commercialization capabilities for those product candidates, if approved.

In addition, we intend to establish collaborations to commercialize our product candidates outside the United States, if approved by the relevant regulatory
authorities.  Therefore,  our  future  success  will  depend,  in  part,  on  our  ability  to  enter  into  and  maintain  collaborative  relationships  for  such  efforts,  the
collaborator’s strategic interest in the product and such collaborator’s ability to successfully market and sell the product. We may not be able to establish or
maintain such collaborative arrangements, or if we are able to do so, such collaborators may not have effective sales forces. To the extent that we depend on
third  parties  for  marketing  and  distribution,  any  revenues  we  receive  will  depend  upon  the  efforts  of  such  third  parties,  and  such  efforts  may  not  be
successful.

Risks Related to Third-Parties' Action on Market Acceptance

Our reliance on third-party suppliers, including single-source suppliers, and a limited number of options for alternate sources for Gvoke or our product
candidates could harm our ability to develop our product candidates or to commercialize Gvoke or any product candidates that are approved.

We do not currently own or operate manufacturing facilities for the production of Gvoke or our product candidates. We rely on third-party suppliers to
manufacture  and  supply  our  products.  We  currently  rely  on  a  number  of  single-source  suppliers,  such  as  Bachem  Americas,  Inc.  ("Bachem")  for  active
pharmaceutical ingredient ("API"), Pyramid Laboratories Inc. ("Pyramid") for drug product and SHL Pharma, LLC ("SHL Pharma") for auto-injector and
final product assembly, and we have entered into several supply agreements including with Bachem, Pyramid and SHL Pharma. Our third-party suppliers
may not be able to produce sufficient inventory to meet commercial demand in a timely manner, or at all. Our third-party suppliers may not be required to
provide us with any guaranteed minimum production levels or have dedicated capacity for our products. As a result, there can be no assurances that we will
be able to obtain sufficient quantities of products, including Gvoke, or other key materials in the future, which could have a material adverse effect on our
business as a whole. For example, the extent to which the COVID-19 pandemic impacts our ability to procure sufficient supplies for the manufacture of
Gvoke or development of our product candidates will depend on the severity and duration of the spread of the virus and the actions undertaken to contain
COVID-19 or treat its effects.

For  us  to  be  successful,  our  third-party  suppliers  must  be  able  to  provide  us  with  raw  materials,  components  and  products  in  substantial  quantities,  in
compliance with regulatory requirements, in accordance with agreed upon specifications, at acceptable costs and on a timely basis. Reliance on third-party
suppliers  entails  risks  to  which  we  would  not  be  subject  if  we  manufactured  products  ourselves,  including  reliance  on  the  third  party  for  regulatory
compliance  and  quality  assurance,  the  possibility  that  products  will  not  be  delivered  on  a  timely  basis,  the  possibility  of  increases  in  pricing  for  our
products, and the possibility of breach or termination of a manufacturing agreement or purchase order by the third party.

Gvoke and some of our product candidates are drug-device combination products that are regulated under the drug regulations of the FDCA based on their
primary  mode  of  action  as  a  drug.  Third-party  manufacturers  may  not  be  able  to  comply  with  the  current  Good  Manufacturing  Practice  ("cGMP")
regulatory  requirements  applicable  to  drug-device  combination  products,  including  applicable  provisions  of  the  FDA’s  drug  cGMP  regulations,  device
cGMP requirements embodied in the Quality System Regulations ("QSRs") 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 our products and product candidates, re-
labeling or re-packaging of our products, operating restrictions and criminal prosecutions, any of which could significantly affect the supply of our products
and product candidates. The facilities used by our contract manufacturers to manufacture our products and product candidates must be approved by the
FDA pursuant to inspections conducted by the FDA. The FDA and other foreign regulatory authorities require manufacturers to register manufacturing
facilities.  We  do  not  control  the  manufacturing  process  of,  and  are  completely  dependent  on,  our  contract  manufacturing  partners  for  compliance  with
cGMPs and QSRs. Contract manufacturers may face manufacturing or quality control problems causing drug substance or device component production
and shipment delays or a situation where the contractor may not be able to maintain compliance with the applicable cGMP or QSR requirements. 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/or 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  foreign  regulatory  authorities  do  not
approve  these  facilities  for  the  manufacture  of  Gvoke  and  if  the  FDA  or  such  foreign  regulatory  authorities  do  not  approve  these  facilities  for  the
manufacture of our product candidates or if they withdraw any such approval in the future, we may need to find alternative manufacturing facilities, which
would significantly impact our ability to market

51

our products or develop, obtain regulatory approval for or market our product candidates, if approved. Contract manufacturers may face manufacturing or
quality control problems causing drug substance production and shipment delays or may not be able to maintain compliance with the applicable cGMP and
QSR requirements. Any failure to comply with cGMP or QSR requirements or other FDA, EMA and comparable foreign regulatory requirements could
adversely affect our research and development activities and our ability to develop our product candidates and market our products and any future products
following approval.

There  are  a  limited  number  of  third-party  suppliers  that  are  compliant  with  cGMP  and/or  QSRs,  as  required  by  the  FDA,  the  EU,  and  other  regulatory
authorities,  and  that  also  have  the  necessary  expertise  and  capacity  to  manufacture  our  materials  and  products.  As  a  result,  it  may  be  difficult  for  us  to
locate third-party suppliers for our anticipated future needs, and our anticipated growth could strain the ability of our current third-party suppliers to deliver
products,  raw  materials  and  components  to  us.  If  we  are  unable  to  arrange  for  third-party  suppliers  for  our  materials  and  products,  or  to  do  so  on
commercially reasonable terms, we may not be able to complete development of or market our products.

The introduction of new cGMP or QSR regulations or product specific requirements by a regulatory body may require that we source alternative materials,
modify existing manufacturing processes or implement design changes to our products that are subject to prior approval by the FDA or other regulatory
authorities. We may also be required to reassess a third-party supplier’s compliance with all applicable new regulations and guidelines, which could further
impede  our  ability  to  manufacture  and  supply  products  in  a  timely  manner.  As  a  result,  we  could  incur  increased  production  costs,  experience  supply
interruptions, suffer damage to our reputation and experience an adverse effect on our business and financial results.

In addition, our reliance on third-party suppliers involves a number of additional risks, including, among other things:

<

<

<

<

<

our  suppliers  may  fail  to  comply  with  regulatory  requirements  or  make  errors  in  manufacturing  raw  materials,  components  or  products  that
could negatively affect the efficacy or safety of our products or cause delays in shipments of our products;
we  may  be  subject  to  price  fluctuations  due  to  terms  within  long-term  supply  arrangements  with  suppliers  or  lack  of  long-term  supply
arrangements for key materials and products;
our suppliers may lose access to critical services or sustain damage to a facility, including losses due to natural disasters, geo-political events, or
epidemics that may result in a sustained interruption in the manufacture and supply of our products;
fluctuations in demand for our products or a supplier’s demand from other customers may affect their ability or willingness to deliver materials
or products in a timely manner or may lead to long-term capacity constraints at the supplier;
we may not be able to find new or alternative sources or reconfigure our products and manufacturing processes in a timely manner if necessary
raw materials or components become unavailable; and
our suppliers may encounter financial or other hardships unrelated to our demand for materials, products and services, which could inhibit their
ability to fulfill our orders and meet our requirements.

If any of the above risks materialize and we are unable to satisfy commercial demand for our products in a timely manner, our ability to generate revenue
would be impaired, market acceptance of our products could be adversely affected, and customers may instead purchase or use our competitors’ products.
In addition, we could be forced to secure new materials or develop alternative third-party suppliers, which can be difficult given our product complexity,
long development lead-times and global regulatory review processes.

If any CMO with whom we contract fails to perform its obligations, we may be forced to manufacture the materials ourselves, for which we may not have
the capabilities or resources, or enter into an agreement with a different CMO, which we may not be able to do on reasonable terms, if at all. In either
scenario, our clinical trials or commercial distribution could be delayed significantly as we establish alternative supply sources. In some cases, the technical
skills required to manufacture our products or product candidates may be unique or proprietary to the original CMO and we may have difficulty, or there
may be contractual restrictions prohibiting us from, transferring such skills to a back-up or alternate supplier, or we may be unable to transfer such skills at
all. In addition, if we are required to change CMOs for any reason, we will be required to verify that the new CMO maintains facilities and procedures that
comply with quality standards and with all applicable regulations. We will also need to verify, such as through a manufacturing comparability study, that
any  new  manufacturing  process  will  produce  our  product  according  to  the  specifications  previously  submitted  to  or  approved  by  the  FDA  or  another
regulatory  authority.  The  delays  associated  with  the  verification  of  a  new  CMO  could  negatively  affect  our  ability  to  develop  product  candidates  or
commercialize our products in a timely manner or within budget. Furthermore, a CMO may possess technology related to the manufacture of our product
candidate that such CMO owns independently. This would increase our reliance on such CMO or require us to obtain a license from such CMO in order to
have another CMO manufacture our products or product candidates. In addition, in the case of the CMOs that supply our products or product candidates,
changes in manufacturers often involve changes in manufacturing procedures and processes, which could require that we conduct bridging studies between
our prior clinical supply used in our clinical trials and that of any new manufacturer. We may be unsuccessful in demonstrating the comparability of clinical
supplies which could require the conduct of additional clinical trials. We are also unable to predict how changing global economic conditions or global
health concerns such as the COVID-19 pandemic will affect our third-party suppliers and manufacturers. Any negative impact of such matters on our third-
party suppliers and manufacturers may also have an adverse impact on our results of operations or financial condition. On March 27, 2020, former

52

 
 
 
President Trump signed into law the CARES Act in response to the U.S. COVID-19 pandemic. Throughout the COVID-19 outbreak, there has been public
concern over the availability and accessibility of critical medical products, and the CARES Act enhances FDA’s existing authority with respect to drug
shortage measures. Under the CARES Act, we must have in place a risk management plan that identifies and evaluates the risks to the supply of approved
drugs for certain serious diseases or conditions for each establishment where the drug or API is manufactured. The risk management plan will be subject to
FDA review during an inspection. If we experience shortages in the supply of our marketed products, our results could be materially impacted.

We may in the future elect to manufacture certain new or existing products ourselves, without the assistance of third-party suppliers. However, in order to
make that election, we will need to invest substantial additional funds and recruit qualified personnel in order to operate our own manufacturing facility on
a commercial basis. There can be no assurance that we will be able to successfully manufacture our own products, and if we are not able to make or obtain
adequate supplies of our raw materials, components or products, it will be more difficult for us to launch new products, supply our current markets and
compete effectively.

Reimbursement decisions by third-party payors may have an adverse effect on pricing and market acceptance. If there is not sufficient reimbursement
for our products, it is less likely that they will be widely used.

Our future revenues and profitability will be adversely affected if U.S. and foreign governmental, private third-party insurers and payors and other third-
party payors, including Medicare and Medicaid, do not agree to defray or reimburse the cost of our products to the patients. If these entities fail to provide
coverage and reimbursement with respect to our products or provide an insufficient level of coverage and reimbursement, our products may be too costly
for some patients to afford them and physicians may not prescribe them. In addition, limitations on the amount of reimbursement for our products may also
reduce our profitability. In the United States and some foreign jurisdictions, there have been, and we expect there will continue to be, actions and proposals
to  control  and  reduce  healthcare  costs.  There  have  been  a  number  of  legislative  and  regulatory  changes  and  proposed  changes  regarding  the  healthcare
system  that  could  prevent  or  delay  marketing  approval  for  our  product  candidates,  restrict  or  regulate  post-approval  activities  and  affect  our  ability  to
profitably  sell  any  of  our  products  or  product  candidates  for  which  we  obtain  marketing  approval.  Government  and  other  third-party  payors  are  also
challenging  the  prices  charged  for  healthcare  products  and  increasingly  limiting,  and  attempting  to  limit,  both  coverage  and  level  of  reimbursement  for
prescription drugs. On December 27, 2018, the District Court for the District of Columbia invalidated a reimbursement formula change under the 340B
program,  which  imposes  ceilings  on  prices  that  drug  manufacturers  can  charge  for  medications  sold  to  certain  healthcare  facilities.  CMS  altered  the
reimbursement formula for fiscal years 2018 and 2019, but the court ruled this change was not an “adjustment” that was within the Secretary’s discretion to
make. On May 6, 2019, the district court reiterated that the rate reduction exceeded the Secretary’s authority and declared that the rate reduction for 2019
also exceeded the Secretary’s authority and remanded the issue to the U.S. Department of Health and Human Services ("HHS") to devise an appropriate
remedy. On July 10, 2019, the district court entered its final judgment and CMS filed an appeal. On July 31, 2020, the United States Court of Appeals for
the District of Columbia Circuit ruled that CMS and HHS did not exceed their authority when it instituted the new reimbursement formula and reversed the
judgment of the district court. On September 14, 2020, the plaintiffs-appellees filed a Petition for Rehearing En Banc (i.e., before the full court), and the
court denied this Petition on October 16, 2020. It is unclear how this could affect covered hospitals who might purchase our products in the future and
affect the rates we may charge such facilities for our approved products.

Market  acceptance  and  sales  of  our  products  and  product  candidates  that  we  develop,  if  approved,  will  depend  on  reimbursement  policies  and  may  be
affected  by  future  healthcare  reform  measures.  Government  authorities  and  third-party  payors,  such  as  private  health  insurers  and  health  maintenance
organizations, decide which drugs they will cover and establish payment levels. In the United States, no uniform policy of coverage and reimbursement for
drugs  exists  among  third-party  payors.  Third-party  payors  often  rely  upon  Medicare  coverage  policy  and  payment  limitations  in  setting  their  own
reimbursement rates, but also have their own methods and approval process apart from Medicare determinations. Therefore, coverage and reimbursement
for drug products can differ significantly from payor to payor. As a result, obtaining coverage and reimbursement approval of a drug from a government or
other  third-party  payor  is  a  time  consuming  and  costly  process  that  could  require  us  to  provide  to  each  payor  supporting  scientific,  clinical  and  cost-
effectiveness data for the use of our drugs on a payor-by-payor basis, with no assurance that coverage and adequate reimbursement will be obtained. We
cannot  be  certain  that  reimbursement  will  be  available  for  any  of  our  product  candidates  or  that  reimbursement  rates  will  not  change  for  our  current
products. Also, we cannot be certain that reimbursement policies will not reduce the demand for, or the price paid for, our products. If reimbursement is not
available or is available on a limited basis, we may not be able to successfully commercialize any of our products or product candidates. Further, due to the
COVID-19  pandemic,  millions  of  individuals  have  lost  or  will  be  losing  employer-based  insurance  coverage,  which  may  adversely  affect  our  ability  to
commercialize Gvoke or our product candidates even if there is adequate coverage and reimbursement from third-party payors.

The United States and several other jurisdictions are considering, or have already enacted, a number of legislative and regulatory proposals to change the
healthcare system in ways that could negatively affect our ability to sell our products profitably. Among policy makers and payors in the United States and
elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality
and/or  expanding  access  to  healthcare.  In  the  United  States,  the  pharmaceutical  industry  has  been  a  particular  focus  of  these  efforts  and  has  been
significantly  affected  by  major  legislative  initiatives.  Furthermore,  third-party  payors  are  increasingly  requiring  that  companies  provide  them  with
predetermined discounts from list prices

53

and are challenging the prices charged for medical products. We expect to experience pricing pressures in connection with the sale of our products that we
develop due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative proposals.

In March 2010, the Patient Protection and Affordable Care Act, as amended by the ACA became law in the United States and is significantly impacting the
provision  of,  and  payment  for,  healthcare.  With  regard  to  pharmaceutical  products  specifically,  the  ACA,  among  other  things,  expanded  and  increased
industry rebates for drugs covered under Medicaid programs and made changes to the coverage requirements under the Medicare prescription drug benefit.
Among other things, the ACA contains provisions that may reduce the profitability of drug products through increased rebates for drugs reimbursed by
Medicaid programs, extension of Medicaid rebates to Medicaid managed care plans, mandatory discounts for certain Medicare Part D beneficiaries and
annual fees based on pharmaceutical companies’ share of sales to federal healthcare programs. On July 24, 2020 and September 13, 2020, former President
Trump signed a series of Executive Orders aimed at lowering drug prices and at implementing several of the administration's proposals. In response, the
FDA released a final rule on September 24, 2020, which went into effect on November 30, 2020, creating a process providing guidance for states to build
and submit to the FDA importation plans for drugs from Canada, as further discussed below. Further, on November 20, 2020 CMS issued an Interim Final
Rule implementing the Most Favored Nation ("MFN") Model under which Medicare Part B reimbursement rates will be calculated for certain drugs and
biologicals  based  on  the  lowest  price  drug  manufacturers  receive  in  Organization  for  Economic  Cooperation  and  Development  countries  with  a  similar
gross domestic product per capita. The MFN Model regulations mandate participation by identified Part B providers and was intended to apply in all U.S.
states and territories for a seven-year period beginning January 1, 2021, and ending December 31, 2027. However, on December 28, 2020, a judge in the
U.S.  District  Court  for  the  Northern  District  of  California  granted  a  preliminary  injunction  prohibiting  CMS  from  implementing  the  MFN  Model.  The
Interim Final Rule has not been finalized and is subject to revision and challenge. On December 2, 2020, HHS published a regulation removing safe harbor
protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers,
unless the price reduction is required by law. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a safe
harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers. Implementation of the amendments to the discount safe
harbor has been delayed to January 1, 2023 pending litigation. Although a number of these, and other proposed measures will require authorization through
additional legislation to become effective, and the Biden Administration may reverse or otherwise change these measures, Congress has indicated that it
will continue to seek new legislative and/or administrative measures to control drug costs. On October 1, 2020, the FDA published a final rule that allows
for the importation of certain prescription drugs from Canada. Under the final rule, states and Indian tribes, and in certain future circumstances pharmacists
and wholesalers, may submit importation program proposals to the FDA for review and authorization. On September 25, 2020, CMS stated drugs imported
by states under this rule will not be eligible for federal rebates under Section 1927 of the Social Security Act and manufacturers would not report these
drugs for “best price” or Average Manufacturer Price purposes. Since these drugs are not considered covered outpatient drugs, CMS further stated it will
not publish a National Average Drug Acquisition Cost for these drugs. Separately, the FDA also issued a final guidance document outlining a pathway for
manufacturers to obtain an additional National Drug Code ("NDC") for an FDA-approved drug that was originally intended to be marketed in a foreign
country and that was authorized for sale in that foreign country. Since the issuance of the final rule, on November 23, 2020, several industry groups filed
federal lawsuits in the U.S. District Court for the District of Columbia, requesting injunctive relief to prevent certification from the Secretary of HHS from
taking effect and challenging multiple aspects of the final rule. This litigation has not progressed. The regulatory and market implications of the Executive
Orders,  the  final  rules  and  final  guidance,  and  any  future  actions  by  the  Biden  Administration  are  unknown  at  this  time,  but  legislation,  regulations  or
policies allowing the reimportation of drugs, if enacted and implemented, could decrease the price we receive for any products that we may develop and
commercialize and could adversely affect our future revenues and prospects for profitability.

Adoption of general controls and measures, coupled with the tightening of restrictive policies in jurisdictions with existing controls and measures, could
limit payments for pharmaceutical drugs. While we cannot predict what impact on federal reimbursement policies this legislation will have in general or on
our business specifically, the ACA may result in downward pressure on pharmaceutical reimbursement, which could negatively affect market acceptance of
our products and our product candidates.

Some patients may require health insurance coverage to afford our products or product candidates, and if we are unable to obtain adequate coverage and
reimbursement  by  third-party  payors,  our  ability  to  successfully  commercialize  our  products  or  product  candidates  may  be  adversely  impacted.  Any
limitation on the use of our products or any decrease in the price of our products will have a material adverse effect on our ability to achieve profitability.

Pricing pressure from healthcare industry consolidation and our competitors may impact our ability to sell our products at prices necessary to support
our current business strategies.

Our market is subject to competitive pricing pressure as a result of product competition and a trend of consolidation in the healthcare industry to aggregate
purchasing power as healthcare costs increase and reforms initiated by legislators, regulators and third-party payors to curb these costs are implemented.

54

For  example,  Eli  Lilly’s  GEK  has  approximately  85%  coverage,  with  unrestricted  access  across  commercial,  Medicare,  Managed  Medicaid  and  state
Medicaid  plans.  Of  our  target  patient  population,  approximately  60%  are  commercially  insured,  approximately  20%  are  covered  by  Medicare,  and
approximately 20% are covered by Medicaid and other government programs. However, as the healthcare industry consolidates, competition to provide
products and services to industry participants has become more intense and may intensify as the potential purchasers of our products or third-party payors
use  their  purchasing  power  to  exert  competitive  pricing  pressure.  We  expect  that  market  demand,  government  regulation,  third-party  coverage  and
reimbursement policies and societal pressures will continue to change the healthcare industry worldwide, resulting in further business consolidations and
alliances among our potential purchasers. If competitive forces drive down the prices we are able to charge for our products, our profit margins will shrink,
which will adversely affect our ability to invest in and grow our business.

The success of Gvoke will be dependent on its proper use by patients, healthcare practitioners and caregivers.

While we have designed Gvoke to be operable by patients, caregivers and healthcare practitioners, we cannot control the successful use of the product by
patients, caregivers and healthcare practitioners. Even though Gvoke was used correctly by individuals in our human factors studies, there is no guarantee
that these results will be replicated by users in the future. If we are not successful in promoting the proper use of Gvoke by patients, healthcare practitioners
and  caregivers,  we  may  not  be  able  to  achieve  market  acceptance  or  effectively  commercialize  Gvoke.  In  addition,  even  in  the  event  of  proper  use  of
Gvoke, individual devices may fail. Increasing the scale of production inherently creates increased risk of manufacturing errors, and we may not be able to
adequately inspect every device that is produced, and it is possible that individual devices may fail to perform as designed. Manufacturing errors could
negatively impact market acceptance of any of our products, result in negative press coverage, or increase the risk that we may be sued.

Guidelines and recommendations can reduce the use of our products.

Government agencies and industry associations such as the American Diabetes Association promulgate guidelines applicable to certain drug classes which
may include our products and product candidates that we are developing. Recommendations from these organizations may relate to such matters as usage,
dosage,  route  of  administration  and  use  of  concomitant  therapies.  Regulations  or  guidelines  affecting  our  products  and  product  candidates  that  we  are
developing  or  the  use  of  competitive  or  alternative  products  as  the  standard  of  care  to  be  followed  by  patients  and  healthcare  providers  could  result  in
decreased use of our products or negatively impact our ability to gain market acceptance and market share.

Risks Related to our Dependence on Third Parties

We depend on third parties to conduct the clinical trials for our product candidates, and any failure of those parties to fulfill their obligations could
harm our development and commercialization plans.

We depend on independent clinical investigators, CROs, academic institutions and other third-party service providers to conduct clinical trials with and for
our product candidates. Although we rely heavily on these parties for successful execution of our clinical trials, we are ultimately responsible for the results
of their activities and many aspects of their activities are beyond our control. For example, we are responsible for ensuring that each of our clinical trials is
conducted  in  accordance  with  the  general  investigational  plan  and  protocols  for  the  trial,  but  the  independent  clinical  investigators  may  prioritize  other
projects over ours or may fail to timely communicate issues regarding our products to us. Third parties may not complete activities on schedule or may not
conduct our clinical trials in accordance with regulatory requirements or our stated protocols. The delay or early termination of any of our clinical trial
arrangements, the failure of third parties to comply with the regulations and requirements governing clinical trials, or our reliance on results of trials that we
have not directly conducted or monitored could hinder or delay the development, approval and commercialization of our product candidates and would
adversely affect our business, results of operations and financial condition.

We maintain compliance programs related to our clinical trials through our clinical operations and development personnel. Our clinical trial vendors are
required to monitor and report to us issues with the conduct of our clinical trials, and we monitor our clinical trial vendors through our clinical, regulatory
and quality assurance staff and other service providers. However, we cannot assure you that our clinical trial vendors or personnel will timely and fully
discover and report any fraud or abuse or other issues that may occur in connection with our clinical trials to us. Such fraud or abuse or other issues, if they
occur and are not successfully remediated, could have a material adverse effect on our research, development, and commercialization activities and results.

55

If our third-party manufacturers of Gvoke or our product candidates are unable to increase the scale of their production of our products or our product
candidates, or increase the product yield of manufacturing, then our costs to manufacture the product may increase and commercialization may be
delayed or interrupted.

In order to produce sufficient quantities to meet the demand for the commercialization of Gvoke, and the clinical trials and subsequent commercialization
of any of our product candidates in our pipeline or that we may develop, our third-party manufacturers will be required to increase their production and
automate and otherwise optimize their manufacturing processes while maintaining the quality of the product. The transition to larger scale production could
prove difficult. In addition, if our third-party manufacturers are not able to automate and otherwise optimize their manufacturing process to increase the
product yield for Gvoke and other components of Gvoke or our product candidates, or if they are unable to produce increased amounts of Gvoke or our
product candidates while maintaining quality, then we may not be able to meet the demands of clinical trials or market demands, which could decrease our
ability  to  generate  revenues  and  have  a  material  adverse  impact  on  our  business  and  results  of  operations.  Any  delay  in  our  third-party  manufacturers'
ability  to  produce  any  of  our  products  could  have  a  material  adverse  effect  on  our  launch  plans,  our  business,  our  results  of  operations  and  financial
condition.

We  expect  to  seek  to  establish  collaborations  and,  if  we  are  not  able  to  establish  them  on  commercially  reasonable  terms,  we  may  have  to  alter  our
development and commercialization plans.

We expect to seek one or more collaborators for the development and commercialization of one or more of our products or product candidates, particularly
with  respect  to  our  pipeline  product  candidates  or  foreign  geographies.  Likely  collaborators  may  include  large  and  mid-size  pharmaceutical  companies,
regional and national pharmaceutical companies and biotechnology companies.

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend, among other
things,  upon  our  assessment  of  the  collaborator’s  resources  and  expertise,  the  terms  and  conditions  of  the  proposed  collaboration  and  the  proposed
collaborator’s  evaluation  of  a  number  of  factors.  Those  factors  may  include  the  potential  differentiation  of  our  product  or  product  candidate  from
competing  products  or  product  candidates,  design  or  results  of  clinical  trials,  the  likelihood  of  approval  by  the  FDA  or  comparable  foreign  regulatory
authorities  and  the  regulatory  pathway  for  any  such  approval,  the  potential  market  for  the  product  or  product  candidate,  the  costs  and  complexities  of
manufacturing and delivering the product to patients and the potential of competing products. The collaborator may also consider alternative products or
product candidates or technologies for similar indications that may be available for collaboration and whether such a collaboration could be more attractive
than the one with us for our product or product candidate. If we elect to increase our expenditures to fund development or commercialization activities on
our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we
may not be able to further develop our product or product candidates or bring them to market and generate product revenue.

Collaborations are complex and time consuming to negotiate and document. Further, there have been a significant number of recent business combinations
among  large  pharmaceutical  companies  that  have  resulted  in  a  reduced  number  of  potential  future  collaborators.  Any  collaboration  agreements  that  we
enter into in the future may contain restrictions on our ability to enter into potential collaborations or to otherwise develop specified product candidates. We
may  not  be  able  to  negotiate  collaborations  on  a  timely  basis,  on  acceptable  terms,  or  at  all.  If  we  are  unable  to  do  so,  we  may  have  to  curtail  the
development  of  the  product  candidate  for  which  we  are  seeking  to  collaborate,  reduce  or  delay  its  development  program  or  one  or  more  of  our  other
development  programs,  delay  its  potential  commercialization  or  reduce  the  scope  of  any  sales  or  marketing  activities,  or  increase  our  expenditures  and
undertake development or commercialization activities at our own expense.

We may be adversely affected by any disruptions to third-party suppliers that manufacture and supply our products.

Any  disruption  to  the  facilities  or  operations  of  our  third-party  suppliers  resulting  from  weather-related  events,  epidemics,  including  the  global  health
concerns such as the COVID-19 pandemic, fire, acts of terrorism, or any other cause could materially impair our ability to manufacture our products and to
distribute  our  products  to  customers.  We  could  incur  significantly  higher  costs  and  longer  lead  times  associated  with  distributing  our  products  to  our
customers. If we are unable to arrange for third-party suppliers of our materials and products, or to do so on commercially reasonable terms, we may not be
able to market our products or product candidates that may be approved in the future. Additionally, our business could be temporarily adversely affected by
higher costs for materials, increased shipping and storage costs, increased labor costs, and scheduling issues. Any interruption in the production or delivery
of our supplies could reduce sales of our products and increase our costs.

Risks Related to the Product Development and Regulatory Approval of Our Product Candidates

Risks Related to Regulatory Approval

We cannot be certain that our product candidates will receive marketing approval. Without marketing approval, we will not be able to commercialize
our product candidates.

We have devoted significant financial resources and business efforts to the development of our product candidates. We cannot be certain that any of our
product candidates will receive marketing approval.

The development of a product candidate and issues relating to its approval and marketing are subject to extensive regulation by the FDA in the United
States and by comparable regulatory authorities in other countries. We are not permitted to market our product candidates in the United States until we
receive approval of a New Drug Application ("NDA") or Biologics License Application ("BLA") from the FDA. The time required to obtain approval by
the FDA and comparable foreign authorities is unpredictable but typically takes many years following the commencement of clinical trials and depends
upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations, or the type and amount
of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions.

NDAs  and  BLAs  must  include  extensive  preclinical  and  clinical  data  and  supporting  information  to  establish  the  product  candidate’s  safety  and
effectiveness for each desired indication. NDAs and BLAs must also include significant information regarding the chemistry, manufacturing and controls
for the product. Obtaining approval of an NDA or BLA is a lengthy, expensive and uncertain process, and we may not be successful in obtaining approval.
Any delay or setback in the regulatory approval or commercialization of any of our product candidates will adversely affect our business.

The FDA has substantial discretion in the drug approval process, including the ability to delay, limit or deny approval of a product candidate for many
reasons. For example, the FDA:

<

<

could determine that we cannot rely on the Section 505(b)(2) regulatory pathway or other pathways we have selected, as applicable, for our
product candidates;
could  determine  that  the  information  provided  by  us  was  inadequate,  contained  clinical  deficiencies  or  otherwise  failed  to  demonstrate  the
safety and effectiveness of our product candidates for any indication;

< may not find the data from bioequivalence studies and/or clinical trials sufficient to support the submission of an NDA or to obtain marketing
approval in the United States, including any findings that the clinical and other benefits of our product candidates outweigh their safety risks;
< may  disagree  with  our  trial  design  or  our  interpretation  of  data  from  preclinical  studies,  bioequivalence  studies  and/or  clinical  trials,  or  may

change the requirements for approval even after it has reviewed and commented on the design for our trials;

< may  determine  that  we  have  identified  the  wrong  listed  drug  or  drugs  or  that  approval  of  our  Section  505(b)(2)  application  for  any  of  our
product  candidates  is  blocked  by  patent  or  non-patent  exclusivity  of  the  listed  drug  or  drugs  or  of  other  previously  approved  drugs  with  the
same conditions of approval as any of our product candidates (as applicable);

< may identify deficiencies in the manufacturing processes or facilities of third-party manufacturers with which we enter into agreements for the

manufacturing of our product candidates;

< may audit some or all of our clinical research and human factors study sites to determine the integrity of our data and may reject any or all of

such data;

< may  approve  our  product  candidates  for  fewer  or  more  limited  indications  than  we  request,  or  may  grant  approval  contingent  on  the

performance of costly post-approval clinical trials;

< may change its approval policies or adopt new regulations; or
< may not approve the labeling claims that we believe are necessary or desirable for the successful commercialization of our product candidates.

Even  if  a  product  is  approved,  the  FDA  may  limit  the  indications  for  which  the  product  may  be  marketed,  require  extensive  warnings  on  the  product
labeling or require expensive and time-consuming clinical trials and/or reporting as conditions of approval. Regulators of other countries and jurisdictions
have their own procedures for approval of product candidates with which we must comply prior to marketing in those countries or jurisdictions.

Obtaining regulatory approval for marketing of a product candidate in one country does not ensure that we will be able to obtain regulatory approval in any
other  country.  In  addition,  delays  in  approvals  or  rejections  of  marketing  applications  in  the  United  States  or  other  countries  may  be  based  upon  many
factors, including regulatory requests for additional analyses, reports, data, preclinical

57

 
 
studies  and  clinical  trials,  regulatory  questions  regarding  different  interpretations  of  data  and  results,  changes  in  regulatory  policy  during  the  period  of
product development and the emergence of new information regarding our product candidates or other products. Also, regulatory approval for any of our
product candidates may be withdrawn.

We intend to utilize the 505(b)(2) pathway for the regulatory approval of certain of our product candidates. If the FDA does not conclude that such
product candidates meet the requirements of Section 505(b)(2), final marketing approval of our product candidates by the FDA or other regulatory
authorities may be delayed, limited, or denied, any of which would adversely affect our ability to generate operating revenues.

We are pursuing a regulatory pathway pursuant to Section 505(b)(2) of the FDCA for the approval of certain of our product candidates, which allows us to
rely on submissions of existing clinical data for the drug. Section 505(b)(2) was enacted as part of the Drug Price Competition and Patent Term Restoration
Act of 1984, or the Hatch-Waxman Amendments, and permits the submission of an NDA where at least some of the information required for approval
comes from preclinical studies or clinical trials not conducted by or for the applicant and for which the applicant has not obtained a right of reference. The
FDA interprets Section 505(b)(2) of the FDCA to permit the applicant to rely upon the FDA’s previous findings of safety and efficacy for an approved
product. The FDA requires submission of information needed to support any changes to a previously approved drug, such as published data or new studies
conducted by the applicant or clinical trials demonstrating safety and efficacy. The FDA could require additional information to sufficiently demonstrate
safety and efficacy to support approval.

If the FDA determines that our product candidates do not meet the requirements of Section 505(b)(2), we may need to conduct additional clinical trials,
provide additional data and information, and meet additional standards for regulatory approval. In March 2010, former President Obama signed into law
legislation creating an abbreviated pathway for approval under the Public Health Service Act, or PHS Act, of biological products that are similar to other
biological products that are approved under the PHS Act. The legislation also expanded the definition of biological product to include proteins such as
insulin. The new law contains transitional provisions governing protein products such as insulin, that, under certain circumstances, might permit companies
to  seek  approval  for  their  insulin  products  as  biologics  under  the  PHS  Act  and  might  require  that  our  XeriSol  pramlintide-insulin  co-formulation  be
approved under the PHS Act rather than in a 505(b)(2) NDA. If our product candidates do not meet the requirements of Section 505(b)(2) or are otherwise
ineligible for approval via the Section 505(b)(2) pathway, the time and financial resources required to obtain FDA approval for these product candidates,
and the complications and risks associated with these product candidates, would likely substantially increase. Moreover, an inability to pursue the Section
505(b)(2) regulatory pathway would likely result in new competitive products reaching the market more quickly than our product candidates, which would
likely materially adversely impact our competitive position and prospects. Even if we are allowed to pursue the Section 505(b)(2) regulatory pathway, we
cannot assure you that our product candidates will receive the requisite approvals for commercialization.

Some  pharmaceutical  companies  and  other  actors  have  objected  to  the  FDA’s  interpretation  of  Section  505(b)(2)  to  allow  reliance  on  the  FDA’s  prior
findings of safety and effectiveness. If the FDA changes its interpretation of Section 505(b)(2), or if the FDA’s interpretation is successfully challenged in
court,  this  could  delay  or  even  prevent  the  FDA  from  approving  any  Section  505(b)(2)  application  that  we  submit.  Moreover,  the  FDA  has  adopted  an
interpretation  of  the  three-year  exclusivity  provisions  whereby  a  505(b)(2)  application  can  be  blocked  by  exclusivity  even  if  it  does  not  rely  on  the
previously approved drug that has exclusivity (or any safety or effectiveness information regarding that drug). Under the FDA’s interpretation, the approval
of  one  or  more  of  our  product  candidates  may  be  blocked  by  exclusivity  awarded  to  a  previously-approved  drug  product  that  shares  certain  innovative
features with our product candidates, even if our 505(b)(2) application does not identify the previously-approved drug product as a listed drug or rely upon
any  of  its  safety  or  efficacy  data.  Any  failure  to  obtain  regulatory  approval  of  our  product  candidates  would  significantly  limit  our  ability  to  generate
revenues, and any failure to obtain such approval for all of the indications and labeling claims we deem desirable could reduce our potential revenues.

Clinical failure may occur at any stage of clinical development, and the results of our clinical trials may not support our proposed indications for our
product candidates. If our clinical trials fail to demonstrate efficacy and safety to the satisfaction of the FDA or other regulatory authorities, we may
incur additional costs or experience delays in completing, or ultimately be unable to complete, the development of such product candidate.

We cannot be certain that existing clinical trial results will be sufficient to support regulatory approval of our product candidates. Success in preclinical
testing and early clinical trials does not ensure that later clinical trials will be successful, and we cannot be sure that the results of later clinical trials will
replicate the results of prior clinical trials and preclinical testing. Moreover, success in clinical trials in a particular indication does not ensure that a product
candidate will be successful in other indications. A number of companies in the pharmaceutical industry have suffered significant setbacks in clinical trials,
even after promising results in earlier preclinical studies or clinical trials or successful later-stage trials in other related indications. These setbacks have
been  caused  by,  among  other  things,  preclinical  findings  made  while  clinical  trials  were  underway  and  safety  or  efficacy  observations  made  in  clinical
trials, including previously unreported adverse events. The results of preclinical and early clinical trials of our product candidates may not be predictive of
the results of later-stage clinical trials. Product candidates in later stages of clinical trials may fail to show the

58

desired  safety  and  efficacy  traits  despite  having  progressed  through  preclinical  and  initial  clinical  trials.  A  failure  of  a  clinical  trial  to  meet  its
predetermined endpoints would likely cause us to abandon a product candidate and may delay development of any of our product candidates. Any delay in,
or  termination  of,  our  clinical  trials  will  delay  the  submission  of  the  applicable  NDA  or  BLA  to  the  FDA,  the  Marketing  Authorization  Application
("MAA") to the European Medicines Agency ("EMA") or other similar applications with other relevant foreign regulatory authorities and, ultimately, our
ability to commercialize our product candidates and generate revenue.

Additional time may be required to obtain regulatory approval for certain of our product candidates because they are combination products.

Certain  of  our  product  candidates  are  drug  and  device  combination  products  that  require  coordination  within  the  FDA  and  similar  foreign  regulatory
agencies for review of their device and drug components. Medical products containing a combination of new drugs, biological products or medical devices
may  be  regulated  as  “combination  products”  in  the  United  States  and  Europe.  A  combination  product  generally  is  defined  as  a  product  comprised  of
components  from  two  or  more  regulatory  categories  (e.g.,  drug/device,  device/biologic,  drug/biologic).  Each  component  of  a  combination  product  is
subject to the requirements established by the FDA for that type of component, whether a new drug, biologic or device. In order to facilitate pre-market
review of combination products, the FDA designates one of its centers to have primary jurisdiction for the pre-market review and regulation of the overall
product  based  upon  a  determination  by  the  FDA  of  the  primary  mode  of  action  of  the  combination  product.  Where  approval  of  the  drug  and  device  is
sought under a single application, there could be delays in the approval process due to the increased complexity of the review process and the lack of a
well-established review process and criteria. The EMA has a parallel review process in place for combination products, the potential effects of which in
terms of approval and timing could independently affect our ability to market our combination products in Europe.

Delays in conducting clinical trials could result in increased costs to us and delay our ability to obtain regulatory approval for our product candidates.

Any delays in conducting clinical trials and related drug development programs could materially affect our product development costs and delay regulatory
approval of our product candidates. We do not know whether planned clinical trials will begin on time, will need to be redesigned, or will be completed on
schedule, if at all. A clinical trial can be delayed for a variety of reasons, including:

<

<

<

<

<

<

<

<

<

<

<

<

delays  or  failures  in  obtaining  regulatory  authorization  to  commence  a  trial  because  of  safety  concerns  of  regulators  relating  to  our  product
candidates  or  similar  product  candidates,  competitive  or  comparator  products  or  supportive  care  products  or  failure  to  follow  regulatory
guidelines;
delays or failures in obtaining clinical materials and manufacturing sufficient quantities of the product candidate for use in a trial;
delays or failures in reaching agreement on acceptable terms with CROs and prospective study sites;
delays or failures in obtaining approval of our clinical trial protocol from an institutional review board ("IRB") to conduct a clinical trial at a
prospective study site;
receipt by a competitor of marketing approval for a product targeting an indication that our product candidate targets, such that we are not “first
to market” with our product candidate;
delays  in  recruiting  or  enrolling  subjects  to  participate  in  a  clinical  trial,  particularly  with  respect  to  our  product  candidates  for  certain  rare
indications, including those for which we have obtained, or plan to seek, orphan drug designation;
failure of a clinical trial or clinical investigators to be in compliance with current Good Clinical Practices ("cGCPs");
unforeseen safety issues;
inability to monitor subjects adequately during or after treatment;
difficulty monitoring multiple study sites;
the FDA requiring alterations to any of our study designs, our nonclinical strategy or our manufacturing plans;
failure of our third-party clinical trial managers to satisfy their contractual duties, comply with regulations, or meet expected deadlines;
determination by regulators that the clinical design of a trial is not adequate; and
disruptions caused by global health concerns, such as the COVID-19 pandemic.

59

Clinical  trials  may  also  be  delayed  or  terminated  as  a  result  of  ambiguous  or  negative  interim  results.  In  addition,  a  clinical  trial  may  be  suspended  or
terminated by us, the FDA, the IRBs at the sites where the IRBs are overseeing a trial, a data safety monitoring board overseeing the clinical trial at issue,
or other regulatory authorities 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 sites by the FDA or other regulatory authorities;
unforeseen safety issues, including serious adverse events associated with a product candidate, or lack of effectiveness; and
lack of adequate funding to continue the clinical trial.

Further, conducting clinical trials in foreign countries, as we have done and may do for certain of our product candidates, presents additional risks that may
delay completion of our clinical trials. These risks include the failure of enrolled patients in foreign countries to adhere to clinical protocol as a result of
differences in healthcare services or cultural customs, managing additional administrative burdens associated with foreign regulatory schemes, as well as
political and economic risks relevant to such foreign countries.

Gvoke  and  our  product  candidates  may  have  undesirable  side  effects  which  may  delay  or  prevent  marketing  approval,  or,  if  approval  is  received,
require them to include safety warnings, require them to be taken off the market or otherwise limit their sales.

Undesirable side effects that may be caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and
could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign authorities. The range and
potential severity of possible side effects from systemic therapies are significant. The results of future clinical trials may show that our product candidates
cause  undesirable  or  unacceptable  side  effects,  which  could  interrupt,  delay  or  halt  clinical  trials,  and  result  in  delay  of,  or  failure  to  obtain,  marketing
approval from the FDA and other regulatory authorities, or result in marketing approval from the FDA and other regulatory authorities with restrictive label
warnings. Recent developments in the pharmaceutical industry have prompted heightened government focus on safety reporting during both pre- and post-
approval time periods and pharmacovigilance. Global health authorities may impose regulatory requirements to monitor safety that may burden our ability
to commercialize our drug products.

To date, patients treated with our ready-to-use glucagon have experienced drug-related side effects typically observed with glucagon products, including
nausea,  vomiting  and  headaches.  Results  of  our  trials  could  reveal  a  high  and  unacceptable  severity  and  prevalence  of  these  or  other  side  effects.  It  is
possible that there may be side effects associated with our product candidates’ use. In such an event, our trials could be suspended or terminated and the
FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all
targeted  indications.  The  drug-related  side  effects  could  affect  patient  recruitment  or  the  ability  of  enrolled  patients  to  complete  the  trial  or  result  in
potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects.

Even if our product candidates receive marketing approval, if we or others later identify undesirable or unacceptable side effects caused by such products or
Gvoke:

regulatory authorities may require the addition of labeling statements, including “black box” warnings, contraindications or dissemination of
field alerts to physicians and pharmacies;
we may be required to change instructions regarding the way the product is administered, conduct additional clinical trials or change the
labeling of the product;
we may be subject to limitations on how we may promote the product;
sales of the product may decrease significantly;
regulatory authorities may require us to take our approved product off the market;
we may be subject to litigation or product liability claims; and
our reputation may suffer.

Any  of  these  events  could  also  prevent  us  from  achieving  or  maintaining  market  acceptance  of  the  affected  product  or  could  substantially  increase
commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenues from the sale of our products.

60

 
 
 
We have received orphan drug designation for our product candidates with respect to certain indications and intend to pursue such designation for
others, but we may be unable to obtain such designation or to maintain the benefits associated with orphan drug status, including market exclusivity,
even if that designation is granted.

We have received orphan drug designation from the FDA for four indications for our product candidates, which are our ready-to-use glucagon for PBH and
Congenital Hyperinsulinism ("CHI") and our ready-to-use diazepam for acute repetitive seizures and Dravet syndrome. We have also received orphan drug
designation  from  the  EMA  for  our  ready-to-use  glucagon  for  CHI  and  Noninsulinoma  Pancreatogenous  Hypoglycaemia  Syndrome  ("NIPHS")  which
includes patients with PBH. We may pursue such designation for others in specific orphan indications in which there is an unmet medical need. Under the
Orphan Drug Act of 1983, the FDA may designate a product candidate as an orphan drug if it is intended to treat a rare disease or condition, which is
generally defined as having a patient population of fewer than 200,000 individuals in the United States, or a patient population greater than 200,000 in the
United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States. Orphan drug
designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-fee waivers.
After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Orphan drug
designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. Although we may seek orphan drug
designation for certain additional indications, we may never receive such designation. Moreover, obtaining orphan drug designation for one indication does
not mean we will be able to obtain such designation for another indication.

If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which it has
such designation, the product is entitled to orphan drug exclusivity. Two of our products, diazepam and glucagon, have been granted separate orphan drug
designations by the FDA. A grant of orphan drug exclusivity related to the approval of the same active moiety and orphan drug indication may prevent us
from seeking FDA approval for marketing in the United States during the exclusivity period except in the case where we are able to demonstrate, and the
FDA concludes, that our drug is “clinically superior” to the approved products, e.g., safer, more effective, or providing a major contribution to patient care
within the meaning of FDA regulations and guidance. In assessing whether we can demonstrate that our drug provides a “major contribution to patient
care” over and above the currently approved drugs, which is evaluated by the FDA on a case by case basis, there is no one objective standard and the FDA
may, in appropriate circumstances, consider such factors as convenience of treatment location, duration of treatment, patient comfort, reduced treatment
burden,  advances  in  ease  and  comfort  of  drug  administration,  longer  periods  between  doses,  and  potential  for  self-administration.  However,  such  a
demonstration to overcome the seven-year market exclusivity may be difficult to establish with limited precedents and there can be no assurance that we
will be successful in these efforts. Orphan drug exclusivity means that the FDA may not approve any other applications, including an NDA, to market the
same drug for the same indication for seven years, except in limited circumstances such as if the FDA finds that the holder of the orphan drug exclusivity
has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for
which  the  drug  was  designated.  Similarly,  the  FDA  can  subsequently  approve  a  drug  with  the  same  active  moiety  for  the  same  condition  during  the
exclusivity  period  if  the  FDA  concludes  that  the  later  drug  is  clinically  superior,  meaning  the  later  drug  is  safer,  more  effective  or  makes  a  major
contribution  to  patient  care.  Even  with  respect  to  the  indications  for  which  we  have  received  orphan  designation,  we  may  not  be  the  first  to  obtain
marketing approval for any particular orphan indication due to the uncertainties associated with developing pharmaceutical products, and thus approval of
our product candidates could be blocked for seven years if another company previously obtained approval and orphan drug exclusivity for the same drug
and same condition. If we do obtain exclusive marketing rights in the United States, they may be limited if we seek approval for an indication broader than
the orphan designated indication and may be lost if the FDA later determines that the request for designation was materially defective or if we are unable to
assure  sufficient  quantities  of  the  product  to  meet  the  needs  of  the  relevant  patients.  Further,  exclusivity  may  not  effectively  protect  the  product  from
competition because different drugs with different active moieties can be approved for the same condition, the same drugs can be approved for different
indications  and  might  then  be  used  off-label  in  our  approved  indication,  and  different  drugs  for  the  same  condition  may  already  be  approved  and
commercially available.

In Europe, the period of orphan drug exclusivity is ten years, although it may be reduced to six years if, at the end of the fifth year, it is established that the
criteria for orphan drug designation are no longer met, in other words, when it is shown on the basis of available evidence that the product is sufficiently
profitable not to justify maintenance of market exclusivity. We have received orphan drug designation from the EMA for our ready-to-use glucagon for the
treatment of CHI and NIPHS, which includes patients with PBH.

Even with the FDA approval of our first product, Gvoke, in the United States and the EMA approval of Ogluo in the European Union, we may not be
able to obtain or maintain foreign regulatory approvals to market our products in other countries.

We do not have any product candidates other than Gvoke approved for sale in the United States, nor any products or product candidates other than Ogluo
approved  for  sale  in  any  international  markets,  and  we  do  not  have  experience  in  obtaining  regulatory  approval  in  international  markets  outside  of  the
European  Union.  In  order  to  market  products  in  any  particular  jurisdiction,  we  must  establish  and  comply  with  numerous  and  varying  regulatory
requirements on a country-by-country basis regarding safety and efficacy. Approval by the FDA in the United States does not ensure approval by regulatory
authorities in other countries or jurisdictions, and

61

approval or certification by one foreign regulatory authority does not ensure approval or certification by regulatory authorities in other foreign countries or
by  the  FDA.  International  jurisdictions  require  separate  regulatory  approvals  and  compliance  with  numerous  and  varying  regulatory  requirements.  The
approval procedures vary among countries and may involve requirements for additional testing, and the time required to obtain approval may differ from
country to country and from that required to obtain clearance or approval in the United States.

In addition, some countries only approve or certify a product for a certain period of time, and we are required to re-approve or re-certify our products in a
timely manner prior to the expiration of our prior approval or certification. We may not obtain foreign regulatory approvals on a timely basis, if at all. We
may not be able to file for regulatory approvals or certifications and may not receive necessary approvals to commercialize our products in any market. If
we fail to receive necessary approvals or certifications to commercialize our products in foreign jurisdictions on a timely basis, or at all, or if we fail to
have our products re-approved or re-certified, our business, results of operations and financial condition could be adversely affected. The foreign regulatory
approval or certification process may include all of the risks associated with obtaining FDA clearance or approval. In addition, the clinical standards of care
may differ significantly such that clinical trials conducted in one country may not be accepted by healthcare providers, third-party payors or regulatory
authorities in other countries, and regulatory approval in one country does not guarantee regulatory approval in any other country. If we fail to comply with
regulatory  requirements  in  international  markets  or  to  obtain  and  maintain  required  approvals,  or  if  regulatory  approvals  in  international  markets  are
delayed, our target market will be reduced and our ability to realize the full market potential of any drug we develop will be unrealized.

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

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

Among  policy  makers  and  payors  in  the  United  States  and  elsewhere,  there  is  significant  interest  in  promoting  changes  in  healthcare  systems  with  the
stated  goals  of  containing  healthcare  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.

In March 2010, former President Obama signed into law the ACA, a sweeping law intended to broaden access to health insurance, reduce or constrain the
growth  of  healthcare  spending,  enhance  remedies  against  fraud  and  abuse,  add  new  transparency  requirements  for  the  healthcare  and  health  insurance
industries, impose new taxes and fees on the health industry and impose additional health policy reforms.

Among the provisions of the ACA of importance to our products and product candidates are the following:

an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic agents, apportioned
among these entities according to their market share in certain government healthcare programs;
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;
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 healthcare fraud and abuse laws, including the False Claims Act and the federal AKS which include, among other things, new
government investigative powers and enhanced penalties for non-compliance;
a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% (increased to 70% effective January
1, 2019 pursuant to the Bipartisan Budget Act of 2018) point-of-sale discounts off negotiated prices of applicable brand drugs to eligible
beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D;
extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care
organizations;
expansion  of  eligibility  criteria  for  Medicaid  programs  by,  among  other  things,  allowing  states  to  offer  Medicaid  coverage  to  additional
individuals, thereby potentially increasing manufacturers’ Medicaid rebate liability;
expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program;
the 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
a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness
research, along with funding for such research.

Since  its  enactment,  some  of  the  provisions  of  the  ACA  have  yet  to  be  fully  implemented,  while  certain  provisions  have  been  subject  to  judicial,
congressional, and executive challenges. As a result, there have been delays in the implementation of, and action taken to repeal or replace, certain aspects
of the ACA. The U.S. Supreme Court has upheld certain key aspects of the legislation, including a tax-based shared responsibility payment imposed on
certain  individuals  who  fail  to  maintain  qualifying  health  coverage  for  all  or  part  of  a  year,  which  is  commonly  known  as  the  requirement  that  all
individuals  maintain  health  insurance  coverage  or  pay  a  penalty,  referred  to  as  the  “individual  mandate.”  However,  as  a  result  of  tax  reform  legislation
passed in December 2017, the individual mandate’s penalty was decreased to $0, effective January 1, 2019. On December 14, 2018, a U.S. District Court
Judge in the Northern District of Texas ruled that the individual mandate is a critical and inseverable feature of the ACA, and therefore, because it was
decreased to $0 as part of the Tax Act, the remaining provisions of the ACA are invalid as well. On December 18, 2019, the Fifth Circuit U.S. Court of
Appeals held the individual mandate is unconstitutional but remanded the case to the lower court to reconsider its earlier invalidation of the full ACA. In
March 2020, the U.S. Supreme Court agreed to hear this case, and oral arguments were held on November 10, 2020. Pending review, the ACA remains in
effect, but it is unclear at this time what effect the latest ruling will have on the status of the ACA. According to the Congressional Budget Office, the
repeal of the individual mandate will cause 13 million fewer Americans to be insured in 2027 and premiums in insurance markets may rise.

On January 20, 2017, former President Trump signed an Executive Order directing federal agencies with authorities and responsibilities under the ACA to
waive, defer, grant exemptions from, or delay the implementation of any provision of the ACA that would impose a fiscal burden on states or a cost, fee,
tax, penalty or regulatory burden on individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices. On October
13, 2017, former President Trump signed an Executive Order terminating the cost-sharing subsidies that reimburse insurers under the ACA. The Trump
administration  concluded  that  cost-sharing  reduction  ("CSR")  payments  to  insurance  companies  required  under  the  ACA  have  not  received  necessary
appropriations  from  Congress  and  announced  that  it  will  discontinue  these  payments  immediately  until  those  appropriations  are  made.  Several  state
Attorneys General filed suit to stop the administration from terminating the subsidies, but their request for a restraining order was denied by a federal judge
in  California  on  October  25,  2017.  On  August  14,  2020,  the  U.S.  Court  of  Appeals  for  the  Federal  Circuit  ruled  in  two  separate  cases  that  the  federal
government is liable for the full amount of unpaid CSRs for the years preceding and including 2017. For CSR claims made by health insurance companies
for years 2018 and later, further litigation will be required to determine the amounts due, if any. Further, on June 14, 2018, the U.S. Court of Appeals for
the Federal Circuit ruled that the federal government was not required to pay more than $12 billion in ACA risk corridor payments to third-party payors
who argued the payments were owed to them. On April 27, 2020, the United States Supreme Court reversed the U.S. Court of Appeals for the Federal
Circuit's  decision  and  remanded  the  case  to  the  U.S.  Court  of  Federal  Claims,  concluding  the  government  has  an  obligation  to  pay  these  risk  corridor
payments under the relevant formula. It is unclear what impact these rulings may have on our business.

In addition, CMS finalized regulations that gives states greater flexibility, as of 2020, in setting benchmarks for insurers in the individual and small group
marketplaces,  which  may  have  the  effect  of  relaxing  the  essential  health  benefits  required  under  the  ACA  for  plans  sold  through  such  marketplaces.
Additionally, CMS finalized a rule, effective January 1, 2020, that allows Medicare Advantage Plans the option of using step therapy for Part B drugs. This
final rule codified CMS’s policy change that was effective January 1, 2019. It is unclear what effect such changes will have on our business.

Other legislative changes have been proposed and adopted since the ACA was enacted including aggregate reductions to Medicare payments to providers
of 2% per fiscal year through 2030. Pursuant to the Coronavirus Aid, Relief, and Economic Security Act, also known as the CARES Act, and subsequent
legislation, these reductions will be suspended from May 1, 2020 through March 31, 2021 due to the COVID-19 pandemic. As the legislation currently
stands, the reductions will go back into effect April 2021 and will remain in effect through 2030; however, proposed legislation, if passed, would extend
this suspension until the end of the pandemic. In January 2013, former President Obama signed into law the American Taxpayer Relief Act of 2012, which,
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. Since 2016, Congress has considered legislation that would repeal or repeal and replace all or part of
the ACA. While Congress has not passed comprehensive repeal legislation, it has enacted laws that modify certain provisions of the ACA such as removing
or  delaying  penalties,  starting  January  1,  2019,  for  not  complying  with  the  ACA’s  individual  mandate  to  carry  health  insurance,  delaying  the
implementation of certain ACA-mandated fees, and increasing the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in
Medicare Part D.

Litigation and legislation over the ACA are likely to continue, with unpredictable and uncertain results. We continue to evaluate the effect that the ACA
and its possible repeal and replacement has on our business. We expect that the ACA, as well as other healthcare reform measures that may be adopted in
the future, may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria, new payment methodologies, and
additional downward pressure on the price that we receive for any approved product. Any reduction in reimbursement from Medicare or other government
programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms
may prevent us from being able to generate revenue, attain profitability or commercialize our products.

63

The cost of prescription pharmaceuticals in the United States has also been the subject of considerable debate, and members of Congress have indicated
that they will address such costs through new legislative measures. To date, there have been several recent U.S. congressional inquiries and proposed state
and federal legislation designed to, among other things, improve transparency in drug pricing, review the relationship between pricing and manufacturer
patient programs, reduce the costs of drugs under Medicare, and reform government program reimbursement methodologies for drug products.

At  the  federal  level,  the  former  Trump  administration’s  budget  proposal  for  fiscal  year  2021  includes  a  $135  billion  allowance  to  support  legislative
proposals seeking to reduce drug prices, increase competition, lower out-of-pocket drug costs for patients, and increase patient access to lower-cost generic
and biosimilar drugs. Additionally, in 2018, the Trump administration released a “Blueprint” to lower drug prices and reduce out-of-pocket costs of drugs
that  contains  additional  proposals  to  increase  manufacturer  competition  and  increase  the  negotiating  power  of  certain  federal  healthcare  programs.
Regarding legislation, on September 25, 2019, the Senate Finance Committee introduced a bill, the Prescription Drug Pricing Reduction Action of 2019,
which  is  intended  to  reduce  Medicare  and  Medicaid  prescription  drug  prices.  The  proposed  legislation  would  restructure  the  Part  D  benefit,  modify
payment methodologies for certain drugs, and impose an inflation cap on drug price increases. An even more restrictive bill was introduced in the House of
Representatives on September 19, 2019, House Resolution 3, the Lower Drug Costs Now Act of 2019, which would require HHS to directly negotiate drug
prices with manufacturers. On December 12, 2019, the Lower Drug Costs Now Act of 2019 passed the House. It is unclear whether either of these bills will
make it through both chambers and be signed into law, and if either is enacted, what effect it would have on our business. At the state level, legislatures are
increasingly 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 pricing of prescription pharmaceuticals is also subject to governmental control outside the United States. In these other countries, pricing negotiations
with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval
in some countries, we may be required to conduct a clinical trial that compares the cost effectiveness of our product candidates to other available therapies.
If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our ability to generate revenues
and become profitable could be impaired.

Legislative  and  regulatory  proposals  have  been  made  to  expand  post-approval  requirements  and  restrict  sales  and  promotional  activities  for  approved
products. In addition, there have been several recent Congressional inquiries and proposed bills designed to, among other things, bring more transparency
to  drug  pricing,  review  the  relationship  between  pricing  and  manufacturer  patient  programs,  reduce  the  cost  of  drugs  under  Medicare  and  reform
government program reimbursement methodologies for drugs. We cannot be sure whether additional legislative changes will be enacted, or whether the
FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our products and product
candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent marketing
approval, as well as subject us to more stringent labeling and post-marketing testing and other requirements.

Risks Related to Product Development

Our failure to successfully identify, develop and market additional product candidates could impair our ability to grow.

As part of our growth strategy, we intend to identify, develop and market additional product candidates leveraging our formulation technology platforms.
We are exploring various therapeutic opportunities for our pipeline programs. We may spend several years completing our development of any particular
current or future internal product candidates, and failure can occur at any stage. The product candidates to which we allocate our resources may not end up
being successful. Our first product, Gvoke, which delivers ready-to-use glucagon via a pre-filled syringe or auto-injector, was approved by the FDA on
September 10, 2019 for the treatment of severe hypoglycemia in pediatric (aged two years and above) and adult patients with diabetes. While we have
identified  several  additional  potential  applications  of  our  ready-to-use  glucagon,  there  is  no  guarantee  that  we  will  be  able  to  utilize  our  formulation
technology platforms to advance additional product candidates.

In  the  future,  we  may  be  dependent  upon  pharmaceutical  companies,  academic  scientists  and  other  researchers  to  sell  or  license  product  candidates,
approved  products  or  the  underlying  technology  to  us.  The  process  of  proposing,  negotiating  and  implementing  a  license  or  acquisition  of  a  product
candidate  or  approved  product  is  lengthy  and  complex.  Other  companies,  including  some  with  substantially  greater  financial,  marketing  and  sales
resources,  may  compete  with  us  for  the  license  or  acquisition  of  product  candidates  and  approved  products.  We  have  limited  resources  to  identify  and
execute the acquisition or in-licensing of third-party products, businesses and technologies and integrate them into our current infrastructure. Moreover, we
may devote resources to potential acquisitions or in-licensing opportunities that are never completed, or we may fail to realize the anticipated benefits of
such efforts. We may not be able to acquire the rights to additional product candidates on terms that we find acceptable, or at all.

64

In addition, future acquisitions may entail numerous operational and financial risks, including: 

  <
<

<

<

<

<

<

  exposure to unknown liabilities;

disruption of our business and diversion of our management’s time and attention to develop acquired products or technologies;
incurrence of substantial debt, dilutive issuances of securities or depletion of cash to pay for acquisitions;
higher than expected acquisition and integration costs;
difficulty in combining the operations and personnel of any acquired businesses with our operations and personnel;
increased amortization expenses;
impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership; and
inability to motivate or retain key employees of any acquired businesses.

Further, any product candidate that we identify internally or acquire would require additional development efforts prior to commercial sale, including
extensive clinical testing and approval by the FDA and other regulatory authorities.

Risks Related to our Industry and Ongoing Legal and Regulatory Requirements

Risks Related to Ongoing Regulatory Obligations

Even after approval of our products and product candidates, we may still face future development and regulatory difficulties. If we fail to comply with
continuing U.S. and non-U.S. regulations or new adverse safety data arise, we could lose our marketing approvals and our business would be seriously
harmed.

Our approved products and product candidates, if approved, will also be subject to ongoing regulatory requirements for manufacturing, distribution, sale,
labeling,  packaging,  storage,  advertising,  promotion,  record-keeping  and  submission  of  safety  and  other  post-market  information.  Approved  products,
third-party  suppliers  and  their  facilities  are  required  to  comply  with  extensive  FDA  requirements  and  requirements  of  other  similar  agencies  even  after
approval, including ensuring that quality control and manufacturing procedures conform to cGMPs and applicable QSRs. As such, we and our third-party
suppliers  are  subject  to  continual  review  and  periodic  inspections,  both  announced  and  unannounced,  to  assess  compliance  with  cGMPs  and  QSRs.
Accordingly,  we  and  our  third-party  suppliers  must  continue  to  expend  time,  money  and  effort  in  all  areas  of  regulatory  compliance,  including
manufacturing, production and quality control. We will also be required to report certain adverse reactions and production problems, if any, to the FDA and
other similar agencies and to comply with certain requirements concerning advertising and promotion for our products. Promotional communications with
respect  to  prescription  drugs  are  subject  to  a  variety  of  legal  and  regulatory  restrictions  and  must  be  consistent  with  the  information  in  the  product’s
approved label. Accordingly, we may not promote our approved products for indications or uses for which they are not approved.

If a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems
with the facility where the product is manufactured, or disagrees with the promotion, marketing or labeling of a product, it may impose restrictions on that
product  or  us,  including  requiring  withdrawal  of  the  product  from  the  market.  These  unknown  problems  could  be  discovered  as  a  result  of  any  post-
marketing follow-up studies, routine safety surveillance or other reporting required as a condition to approval.

Regulatory agencies may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of a
product.  The  FDA  and  other  agencies,  including  the  Department  of  Justice  ("DOJ"),  closely  regulate  and  monitor  the  post-approval  marketing  and
promotion  of  products  to  ensure  that  they  are  manufactured,  marketed  and  distributed  only  for  the  approved  indications  and  in  accordance  with  the
provisions of the approved labeling. The FDA imposes stringent restrictions on manufacturers’ communications regarding off-label use, and if we, or any
future collaborators, do not market any of our products for which we, or they, receive marketing approval for only their approved indications, we, or they,
may  be  subject  to  warnings  or  enforcement  action  for  off-label  marketing,  government  investigations,  or  litigation.  Violation  of  the  FDCA  and  other
statutes,  including  the  False  Claims  Act,  relating  to  the  promotion  and  advertising  of  prescription  drugs  may  lead  to  investigations  or  allegations  of
violations of federal and state healthcare fraud and abuse laws and state consumer protection laws. On August 14, 2020, we received an untitled letter from
FDA’s  Office  of  Prescription  Drug  Promotion  regarding  a  promotional  television  advertisement  for  Gvoke  PFS.  The  letter  raised  concerns  that  the
advertisement  did  not  include  sufficient  risk  information,  made  misleading  claims  as  to  the  product’s  ease  of  use,  and  omitted  information  about  the
seriousness  of  the  condition  for  which  Gvoke  PFS  is  indicated  and  the  circumstances  when  it  is  appropriate  to  administer  Gvoke  PFS.  The  television
advertisement cited in the untitled letter was discontinued in March of 2020. We have submitted a response to the FDA regarding our plan to revise the
advertisement at issue and are in discussions with the FDA.

65

 
If  our  products  or  product  candidates  fail  to  comply  with  applicable  regulatory  requirements,  or  if  a  problem  with  one  of  our  products  or  third-party
suppliers is discovered, a regulatory agency may:

  <
<

<

<

<

<

<

<

<

<

<

<

  restrict the marketing or manufacturing of such products;

restrict or require modification of or revision to the labeling of a product;
issue warning letters or untitled letters which may require corrective action;
mandate modifications to promotional materials or require us to provide corrective information to healthcare practitioners;
require us to enter into a consent decree or permanent injunction, which can include imposition of various fines, reimbursements for inspection
costs, required due dates for specific actions and penalties for noncompliance;
impose other administrative or judicial civil or criminal penalties including fines, imprisonment and disgorgement of profits;
suspend or withdraw regulatory approval;
refuse to approve pending applications or supplements to approved applications filed by us;
close the facilities of our third-party suppliers;
suspend ongoing clinical trials;
impose restrictions on operations, including costly new manufacturing requirements; or
seize or detain products or recommend or require a product recall.

The FDA’s and foreign regulatory agencies’ policies are subject to change, and additional federal, state, local or non-U.S. governmental regulations may be
enacted that could affect our ability to maintain compliance. We cannot predict the likelihood, nature or extent of adverse governmental regulation that may
arise from future legislation or administrative action, either in the United States or abroad.

Our relationships with customers and payors will be subject to applicable anti-kickback, fraud and abuse, transparency, and other healthcare laws and
regulations,  which  could  expose  us  to  criminal  sanctions,  civil  penalties,  contractual  damages,  reputational  harm,  administrative  burdens  and
diminished profits and future earnings.

Healthcare  providers,  physicians  and  third-party  payors  will  play  a  primary  role  in  the  recommendation  and  prescription  of  any  products  for  which  we
obtain marketing approval. Our future arrangements with investigators, healthcare practitioners, consultants, third-party payors and customers, if any, will
subject  us  to  broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and  regulations.  These  laws  and  regulations  may  constrain  the  business  or
financial arrangements and relationships through which we conduct our operations, including how we research, market, sell and distribute any products for
which we obtain marketing approval. These include the following:

<

Anti-Kickback Statute. The federal AKS makes it illegal for any person or entity (including a prescription drug manufacturer or a party acting
on its behalf) to knowingly and willfully solicit, offer, receive or pay remuneration, directly or indirectly, in cash or in kind, in exchange for or
intended to induce or reward either the referral of an individual for, or the purchase, order, prescription or recommendation or arranging of, any
good or service, for which payment may be made under a federal healthcare program such as Medicare and Medicaid. This statute has been
interpreted  to  apply  to  arrangements  between  pharmaceutical  manufacturers  on  the  one  hand  and  prescribers,  purchasers  and  formulary
managers on the other. Although there are several statutory exceptions and regulatory safe harbors protecting certain common activities from
prosecution,  they  are  drawn  narrowly,  and  practices  that  involve  remuneration  intended  to  induce  prescribing,  purchasing  or  recommending
may be subject to scrutiny if they do not qualify for an exception or safe harbor. A person or entity can be found guilty of violating the AKS
without actual knowledge of the statute or specific intent to violate it. In addition, the government may assert that a claim including items or
services resulting from a violation of the AKS constitutes a false or fraudulent claim for purposes of the federal False Claims Act or federal
civil  money  penalties  statute.  Violations  of  the  AKS  carry  potentially  significant  civil  and  criminal  penalties,  including  imprisonment,  fines,
administrative  civil  monetary  penalties,  and  exclusion  from  participation  in  federal  healthcare  programs.  On  December  2,  2020,  the  OIG
published further modifications to the federal Anti-Kickback Statute in the Federal Register. Under the final rule, the OIG added safe harbor
protections under the Anti-Kickback Statute for certain coordinated care and value-based arrangements among clinicians, providers, and others.
On  the  same  day,  CMS  published  a  final  rule  that  provides  a  safe  harbor  for  value-based  compensation  agreements  under  the  Stark  Law.
However, the GAO found that these final rules did not meet the sixty-day delay required under the Congressional Review Act. Additionally, on
January 20, 2021, the Biden Administration issued a moratorium on all Trump-era rules that have not yet taken effect. The interplay between
the GAO’s findings and the Biden Administration’s moratorium, which will determine whether these two rules are in effect, is unclear;

66

<

False Claims Laws. The federal civil and criminal false claims and civil monetary penalties laws, including the federal FCA,
prohibit  individuals  or  entities  from,  among  other  things,  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal
government, claims for payment or approval that are false, fictitious or fraudulent; knowingly making, using or causing to be
made  or  used  a  false  statement  or  record  material  to  a  false  or  fraudulent  claim  or  obligation  to  pay  or  transmit  money  or
property  to  the  federal  government;  or  knowingly  concealing  or  knowingly  and  improperly  avoiding  or  decreasing  an
obligation to pay money to the federal government. Manufacturers can be held liable under the FCA even when they do not
submit  claims  directly  to  government  payors  if  they  are  deemed  to  “cause”  the  submission  of  false  or  fraudulent  claims.
Companies that submit claims directly to payors also may be liable under the FCA for the direct submission of such claims.
The FCA also permits a private individual acting as a “whistleblower” to bring actions on behalf of the federal government
alleging  violations  of  the  FCA  and  to  share  in  any  monetary  recovery.  When  an  entity  is  determined  to  have  violated  the
federal civil False Claims Act, the government may impose civil fines and penalties for each false claim, plus treble damages,
and exclude the entity from participation in Medicare, Medicaid and other federal healthcare programs.

<

< Anti-Inducement Law. The anti-inducement law prohibits, among other things, the offering or giving of remuneration, which
includes,  without  limitation,  any  transfer  of  items  or  services  for  free  or  for  less  than  fair  market  value  (with  limited
exceptions),  to  a  Medicare  or  Medicaid  beneficiary  that  the  person  knows  or  should  know  is  likely  to  influence  the
beneficiary’s selection of a particular supplier of items or services reimbursable by a federal or state governmental program.
< HIPAA. The  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  as  amended  by  HITECH  and
their  respective  implementing  regulations,  imposes  criminal  and  civil  liability  for,  among  other  things,  knowingly  and
willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program (including private payors)
or making false or fraudulent statements relating to healthcare matters. Similar to the federal AKS, a person or entity does not
need  to  have  actual  knowledge  of  the  statute  or  specific  intent  to  violate  it  in  order  to  have  committed  a  violation.
Additionally, HIPAA, as amended by HITECH and its implementing regulations, also imposes obligations on certain covered
healthcare  providers,  health  plans,  and  healthcare  clearinghouses  (“covered  entities”)  and  their  business  associates  that
perform services for them that involve the use, or disclosure of, individually identifiable health information, relating to the
privacy, security and transmission of individually identifiable health information, including mandatory contractual terms and
technical  safeguards,  with  respect  to  maintaining  the  privacy,  security  and  transmission  of  individually  identifiable  health
information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties
directly applicable to 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.
Transparency Requirements. The federal Physician Payments Sunshine Act requires certain manufacturers of drugs, devices,
biologics, and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance
Program, with specific exceptions, to report annually to HHS information regarding any payment or other “transfer of value”
made  or  distributed  to  healthcare  professionals  (currently  defined  to  include  doctors,  dentists,  optometrists,  podiatrists,  and
chiropractors) and teaching hospitals, as well as ownership and investment interests held by the healthcare professionals and
their  immediate  family  members.  Failure  to  submit  required  information  may  result  in  civil  monetary  penalties  for  all
payments, transfers of value or ownership or investment interests that are not timely, accurately, and completely reported in an
annual  submission.  Effective  January  1,  2022,  these  reporting  obligations  will  extend  to  include  transfers  of  value  made  to
certain additional healthcare professionals. 
Analogous  State  and  Foreign  Laws. Analogous  state  and  foreign  fraud  and  abuse  laws  and  regulations,  such  as  state  anti-
kickback and false claims laws, can apply to our business practices, including but not limited to, research, distribution, sales
and marketing arrangements, and claims involving healthcare items or services reimbursed by non-governmental third-party
payors,  and  are  generally  broad  and  are  enforced  by  many  different  federal  and  state  agencies  as  well  as  through  private
actions.  Some  state  laws  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  healthcare  providers  and  other  potential  referral  sources,  and  some  state  laws  require  drug
manufacturers  to  report  information  related  to  payments  and  other  transfers  of  value  to  physicians  and  other  healthcare
providers or marketing expenditures and pricing information. State and foreign laws also govern the privacy and security of
health information in some circumstances, many of which differ from each other in significant ways and often are not pre-
empted by HIPAA, thus complicating compliance efforts.

<

Efforts to ensure that our business arrangements with third parties, and our business generally, will comply with applicable healthcare laws and regulations
involve substantial costs. It is possible that governmental authorities will conclude that our business practices, including our arrangements with physicians
and other healthcare providers, some of whom may receive stock options as compensation for services provided, may not comply with current or future
statutes, regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found
to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and
administrative  penalties,  damages,  fines,  imprisonment,  exclusion  of  products  from  government  funded  healthcare  programs,  such  as  Medicare  and
Medicaid, disgorgement, contractual damages, reputational harm and the curtailment or restructuring of our operations. Defending against any such actions
can be costly and time consuming and may require significant financial and personnel resources. Therefore, even if we are successful in defending against
any such actions that may be brought against us, our business may be impaired. Further, if any of the physicians or other healthcare providers or entities
with  whom  we  expect  to  do  business  is  found  to  be  not  in  compliance  with  applicable  laws,  they  may  be  subject  to  criminal,  civil  or  administrative
sanctions, including exclusions from government funded healthcare programs.

European data collection is governed by restrictive regulations governing the use, processing and cross-border transfer of personal information.

We  have  conducted  and  may  in  the  future  conduct  clinical  trials  in  the  European  Union  ("EU")  subjecting  us  to  additional  privacy  restrictions.  The
collection and use of personal health data in the EU are governed by the provisions of the General Data Protection Regulation ("GDPR"). This regulation
imposes  several  requirements  relating  to  the  consent  of  the  individuals  to  whom  the  personal  data  relates,  the  information  provided  to  the  individuals,
notification of data processing obligations to the competent national data protection authorities and the security and confidentiality of the personal data.

The GDPR also regulates the transfers of EU and European Economic Area ("EEA") individuals’ personal data to other countries that have been deemed
by the European Commission not to provide adequate protection to personal data. The U.S. is not deemed to have adequate laws to protect personal data.
We had relied upon the EU-U.S. Privacy Shield program to legitimize certain transfers of personal data from the EU and EEA to the U.S. However, on July
16, 2020, the European Court of Justice ("ECJ") invalidated the EU-U.S. Privacy Shield program that we (along with thousands of other companies) have
utilized to transfer data from the EU and EEA to the U.S. in compliance with GDPR. As a result of this decision, companies like us that previously relied
upon Privacy Shield will be required to use another GDPR-approved method to legitimize transfers of personal data to the U.S. and other third countries in
compliance with the GDPR. Although in its ruling about the Privacy Shield, the ECJ deemed that the Standard Contractual Clauses ("SCCs") approved by
the European Commission for transfers of personal data between EU controllers and non-EU processors are valid, the Court also noted that transfers made
pursuant  to  the  SCCs  need  to  be  analyzed  on  a  case-by-case  basis  to  ensure  EU  standards  of  data  protection  are  met  in  the  jurisdiction  where  the  data
importer is based, and there continue to be concerns about whether the SCCs (including SCCs for controller-to-controller transfers) will face additional
challenges.  Further,  EU  member  state  data  protection  authorities  are  empowered  to  evaluate  the  adequacy  of  the  SCCs  adopted  by  businesses  in  any
specific case and they are required to suspend or ban data transfers to a third country if, in the light of all the circumstances of that transfer, the SCCs are
not or cannot be complied with in that country. Until the remaining legal uncertainties regarding how to legally continue these transfers are settled, we will
continue to face uncertainty as to whether our efforts to comply with our obligations under European privacy laws will be sufficient. If we are investigated
by a European data protection authority, we may face fines and other penalties, including bans on processing and transferring personal data. This and other
future  developments  regarding  the  flow  of  data  across  borders  could  increase  the  cost  and  complexity  of  delivering  our  products  and  services  in  some
markets and may lead to governmental enforcement actions, litigation, fines and penalties or adverse publicity, which could have an adverse effect on our
reputation and business.

Laws and regulations governing any international operations we may have in the future may preclude us from developing, manufacturing and selling
certain product candidates outside the United States and require us to develop and implement costly compliance programs.

We currently have operations in the United States, and we maintain relationships with CMOs in certain parts of Europe, Asia and the United States for the
manufacture of our products and product candidates. The Foreign Corrupt Practices Act ("FCPA") prohibits any U.S. individual or business from paying,
offering, authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of
influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates
companies  whose  securities  are  listed  in  the  United  States  to  comply  with  certain  accounting  provisions  requiring  the  company  to  maintain  books  and
records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate
system  of  internal  accounting  controls  for  international  operations.  The  anti-bribery  provisions  of  the  FCPA  are  enforced  primarily  by  the  DOJ.  The
Securities  and  Exchange  Commission  ("SEC")  is  involved  with  enforcement  of  the  books  and  records  provisions  of  the  FCPA  and  may  suspend  or  bar
issuers from having its securities traded on U.S. exchanges for violations of the FCPA’s accounting provisions.

Various  laws,  regulations  and  executive  orders  also  restrict  the  use  and  dissemination  outside  the  United  States,  or  the  sharing  with  certain  non-U.S.
nationals, of information classified for national security purposes, as well as certain products and technical data relating to those products. As we expand
our presence outside the United States, we are required to dedicate additional resources to comply with laws and regulations in each new jurisdiction in
which we are operating or plan to operate, and these laws may preclude us from developing, manufacturing, or selling certain drugs and product candidates
outside the United States, which could limit our growth potential and increase our development costs.

The creation and implementation of international business practices compliance programs, particularly FCPA compliance, are costly and such programs are
difficult  to  enforce,  especially  in  countries  in  which  corruption  is  a  recognized  problem  and  where  reliance  on  third  parties  is  required.  In  addition,  the
FCPA presents particular challenges in the pharmaceutical industry because, in many countries, hospitals are operated by the government, and doctors and
other hospital employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials and other work have been deemed
to be improper payments to government officials and have led to FCPA enforcement actions. Indictment alone under the FCPA can lead to suspension of
the right to do business with the U.S. government until the pending claims are resolved. Conviction of a violation of the FCPA can result in long-term
disqualification as a government contractor.

68

Accordingly, our failure to comply with the FCPA or other export control, anti-corruption, anti-money laundering and anti-terrorism laws or regulations and
other  similar  laws  governing  international  business  practices  may  result  in  substantial  penalties,  including  suspension  or  debarment  from  government
contracting. The termination of a government contract or relationship as a result of our failure to satisfy any of our obligations under such laws would have
a  negative  impact  on  our  operations  and  harm  our  reputation  and  ability  to  procure  government  contracts.  We  cannot  assure  you  that  our  compliance
policies and procedures are or will be sufficient or that our directors, officers, employees, representatives, consultants and agents have not engaged and will
not engage in conduct for which we may be held responsible, nor can we assure you that our business partners have not engaged and will not engage in
conduct that could materially affect their ability to perform their contractual obligations to us or even result in our being held liable for such conduct.

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

In  some  countries,  such  as  the  countries  of  the  EU,  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 product. In addition, there can be
considerable pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost containment measures. Political,
economic  and  regulatory  developments  may  further  complicate  pricing  negotiations,  and  pricing  negotiations  may  continue  after  coverage  and
reimbursement have been obtained. Reference pricing used by various countries and parallel distribution or arbitrage between low-priced and high-priced
countries can further reduce prices. To obtain reimbursement or pricing approval in some countries, we, or any future collaborators, may be required to
conduct a clinical trial that compares the cost-effectiveness of our product candidates to other available therapies, which is time consuming and costly. If
reimbursement of our product candidates is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be
harmed.

We will need to obtain FDA approval of any proposed product names, and any failure or delay associated with such approval may adversely impact our
business.

Any name we intend to use for our product candidates will require approval from the FDA regardless of whether we have secured a trademark registration
from  the  U.S.  Patent  and  Trademark  Office  ("USPTO").  The  FDA  typically  conducts  a  review  of  proposed  product  names,  including  an  evaluation  of
potential  for  confusion  with  other  product  names.  The  FDA  may  object  to  any  product  name  we  submit  if  it  believes  the  name  inappropriately  implies
medical claims. If the FDA objects to any of our proposed product names, we may be required to adopt an alternative name for our product candidates. If
we adopt an alternative name, we would lose the benefit of any existing trademark applications for such product candidate and may be required to expend
significant additional resources in an effort to identify a suitable product name that would qualify under applicable trademark laws, not infringe the existing
rights of third parties and be acceptable to the FDA. We may be unable to build a successful brand identity for a new trademark in a timely manner or at all,
which would limit our ability to commercialize our product 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
have a material adverse effect on our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use,
storage, treatment and disposal of hazardous materials and wastes. From time to time and in the future, our operations may involve the use of hazardous
and flammable materials, including chemicals and biological materials, and may also produce hazardous waste products. Even if we contract with third
parties  for  the  disposal  of  these  materials  and  waste  products,  we  cannot  completely  eliminate  the  risk  of  contamination  or  injury  resulting  from  these
materials. In the event of contamination or injury resulting from the use or disposal of our 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.

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,  but  this  insurance  may  not  provide  adequate  coverage  against  potential  liabilities.  However,  we  do  not  maintain  insurance  for
environmental liability or toxic tort claims that may be asserted against us.

In  addition,  we  may  incur  substantial  costs  in  order  to  comply  with  current  or  future  environmental,  health  and  safety  laws  and  regulations.  Current  or
future environmental laws and regulations may impair our research, development or production efforts. In addition, failure to comply with these laws and
regulations may result in substantial fines, penalties or other sanctions.

Risks Related to Industry Competition

We operate in a competitive business environment and, if we are unable to compete successfully against our existing or potential competitors, our sales
and operating results may be negatively affected and we may not successfully commercialize our products or product candidates, even if approved.

The pharmaceutical and biotechnology industries are characterized by intense competition and significant and rapid technological change as researchers
learn  more  about  diseases  and  develop  new  technologies  and  treatments.  Any  product  candidates  that  we  successfully  develop  and  commercialize  will
compete with existing drugs and new drugs that may become available in the future. While we believe that our product and product candidate platform,
development  expertise  and  scientific  knowledge  provide  us  with  competitive  advantages,  we  face  potential  competition  from  many  different  sources,
including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions and governmental agencies and public and
private research institutions. Many of our current and potential competitors are major pharmaceutical companies that have substantially greater financial,
technical and marketing resources than we do, and they may succeed in developing products that would render our products obsolete or noncompetitive.
Our ability to compete successfully will depend on our ability to develop future products that reach the market in a timely manner, are well adopted by
patients and healthcare providers and receive adequate coverage and reimbursement from third-party payors. Because of the size of the potential market,
we anticipate that companies will dedicate significant resources to developing products competitive to our product candidates.

For example, we have numerous competitors in the severe hypoglycemia market, which currently include Eli Lilly’s Baqsimi®, an intranasal glucagon dry
powder, Eli Lilly's GEK, Novo Nordisk’s GlucaGen HypoKit and Fresenius Kabi's glucagon emergency kit for low blood sugar. Amphastar's ANDA for
generic  Glucagon  for  Injection  Emergency  Kit  was  approved  by  the  FDA  on  December  29,  2020  for  the  treatment  of  severe  hypoglycemia.  Zealand
Pharma has submitted a New Drug Application for their dasiglucagon auto-injector HypoPal® which has been accepted by the FDA with a PDUFA target
action  date  of  March  27,  2021.  At  any  time,  these  or  other  industry  participants  may  develop  alternative  treatments,  products  or  procedures  for  the
treatment of severe hypoglycemia that compete directly or indirectly with Gvoke. Competitors may also develop and patent processes or products earlier
than we can or obtain regulatory clearance or approvals for competing products more rapidly than we can, which could impair our ability to develop and
commercialize similar processes or products. If alternative treatments are, or are perceived to be, superior to our products, sales of our products or product
candidates, if approved, could be negatively affected and our results of operations could suffer.

The widespread acceptance of currently available therapies with which our product candidates will compete may limit market acceptance of Gvoke or our
product candidates even if approved and commercialized. For example, traditional glucagon kits currently available for hypoglycemia are widely accepted
in  the  medical  community  and  have  a  long  history  of  use.  These  treatments  compete  with  Gvoke  and  may  limit  the  potential  for  Gvoke  to  receive
widespread acceptance.

If the FDA approves a competitor’s application for a product candidate or drug-device combination product before our application for a similar product
candidate or drug-device combination product, and grants such competitor a period of exclusivity, the FDA may take the position that it cannot approve our
505(b)(2)  application  for  a  similar  product  candidate  until  the  exclusivity  period  expires.  Additionally,  even  if  our  505(b)(2)  application  for  a  product
candidate is approved first, and we receive three-year marketing exclusivity, we may still be subject to competition from other companies with approved
products or approved 505(b)(2) NDAs for different conditions of use that would not be restricted by a grant of exclusivity to us.

If the FDA or other applicable regulatory authorities approve generic products that compete with any of our products or product candidates, the sales
of our product candidates, if approved, could be adversely affected.

Once  an  NDA,  including  a  Section  505(b)(2)  application,  is  approved,  the  product  covered  becomes  a  “listed  drug”  which  can  be  cited  by  potential
competitors  in  support  of  approval  of  an  abbreviated  new  drug  application  ("ANDA").  FDA  regulations  and  other  applicable  regulations  and  policies
provide incentives to manufacturers to create modified versions of a drug to facilitate the approval of an ANDA or other application for similar substitutes.
If these manufacturers demonstrate that their product has the same active ingredient(s), dosage form, strength, route of administration, and conditions of
use, or labeling, as our products or product candidates, they might only be required to conduct a relatively inexpensive study to show that their generic
product is absorbed in the body at the same rate and to the same extent as, or is bioequivalent to, our products or product candidates. In some cases, even
this  limited  bioequivalence  testing  can  be  waived  by  the  FDA.  Competition  from  generic  equivalents  to  our  products  or  product  candidates  could
substantially limit our ability to generate revenues and therefore to obtain a return on the investments we have made in our products or product candidates.
For example, Amphastar's ANDA for generic Glucagon for Injection Emergency Kit was approved by the FDA on December 29, 2020 for the treatment of
severe hypoglycemia.

70

Recent federal legislation and actions by federal, state and local governments may permit reimportation of drugs from foreign countries into the United
States,  including  foreign  countries  where  the  drugs  are  sold  at  lower  prices  than  in  the  United  States,  which  could  materially  adversely  affect  our
operating results.

We may face competition in the United States for products and development candidates and investigational medicines, if approved, from therapies sourced
from  foreign  countries  that  have  placed  price  controls  on  pharmaceutical  products.  In  the  United  States,  the  Medicare  Modernization  Act  ("MMA")
contains  provisions  that  call  for  the  promulgation  of  regulations  that  expand  pharmacists’  and  wholesalers’  ability  to  import  cheaper  versions  of  an
approved drug and competing products from Canada, where there are government price controls. Further, the MMA provides that these changes to U.S.
importation laws will not take effect, unless and until the Secretary of the HHS certifies that the changes will pose no additional risk to the public’s health
and safety and will result in a significant reduction in the cost of products to consumers. On September 23, 2020, the Secretary of the HHS made such
certification to Congress, and on October 1, 2020, FDA published a final rule that allows for the importation of certain prescription drugs from Canada.
Under the final rule, States and Indian Tribes, and in certain future circumstances pharmacists and wholesalers, may submit importation program proposals
to  the  FDA  for  review  and  authorization.  On  September  25,  2020,  CMS  stated  drugs  imported  by  States  under  this  rule  will  not  be  eligible  for  federal
rebates  under  Section  1927  of  the  Social  Security  Act  and  manufacturers  would  not  report  these  drugs  for  “best  price”  or  Average  Manufacturer  Price
purposes. Since these drugs are not considered covered outpatient drugs, CMS further stated it will not publish a National Average Drug Acquisition Cost
for these drugs. Separately, the FDA also issued a final guidance document outlining a pathway for manufacturers to obtain an additional National Drug
Code ("NDC") for an FDA-approved drug that was originally intended to be marketed in a foreign country and that was authorized for sale in that foreign
country. The market implications of the final rule and guidance are unknown at this time. Proponents of drug reimportation may attempt to pass legislation
that  would  directly  allow  reimportation  under  certain  circumstances.  Legislation  or  regulations  allowing  the  reimportation  of  drugs,  if  enacted,  could
decrease the price we receive for any products that we may develop and adversely affect our future revenues and prospects for profitability.

Risks Related to Our Intellectual Property

Risks Related to Protecting Our Intellectual Property

Our success depends on our ability to protect our intellectual property and proprietary technology, as well as the ability of our collaborators to protect
their intellectual property and proprietary technology.

Our success depends in large part on our ability to obtain and maintain patent protection and trade secret protection in the United States and other countries
with respect to our proprietary product candidates and their use. If we do not adequately protect our intellectual property rights, competitors may be able to
erode or negate any competitive advantage we may have, which could harm our business and ability to achieve profitability. To protect our proprietary
position, we file patent applications in the United States and abroad related to our novel product candidates that are important to our business; we may in
the future also license or purchase patents or applications owned by others. The patent application and approval process is expensive and time consuming.
We may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner.

If the scope of the patent protection we or our potential licensors obtain is not sufficiently broad, we may not be able to prevent others from developing and
commercializing  technology  and  products  similar  or  identical  to  ours.  The  degree  of  patent  protection  we  require  to  successfully  compete  in  the
marketplace may be unavailable or severely limited in some cases and may not adequately protect our rights or permit us to gain or keep any competitive
advantage. We cannot provide any assurances that any of our patents have, or that any of our pending patent applications that mature into issued patents
will  include,  claims  with  a  scope  sufficient  to  protect  our  current  and  future  product  candidates  or  otherwise  provide  any  competitive  advantage.  In
addition, to the extent that we license intellectual property in the future, we cannot assure you that those licenses will remain in force. In addition, the laws
of  foreign  countries  may  not  protect  our  rights  to  the  same  extent  as  the  laws  of  the  United  States.  Furthermore,  patents  have  a  limited  lifespan.  In  the
United States, the natural expiration of a patent is generally twenty years after it is filed. Various extensions may be available; however, the life of a patent
and the protection it affords are limited. Given the amount of time required for the development, testing and regulatory review of new product candidates,
patents protecting such candidates might expire before or shortly after such candidates are commercialized.

Even  if  they  are  unchallenged,  our  patents  and  pending  patent  applications,  if  issued,  may  not  provide  us  with  any  meaningful  protection  or  prevent
competitors from designing around our patent claims to circumvent our patents by developing similar or alternative technologies or therapeutics in a non-
infringing manner. For example, a third party may develop a competitive therapy that provides benefits similar to one or more of our products or product
candidates but that uses a formulation and/or a device that falls outside the scope of our patent protection. If the patent protection provided by the patents
and  patent  applications  we  hold  or  pursue  with  respect  to  our  products  or  product  candidates  is  not  sufficiently  broad  to  exclude  such  competition,  our
ability  to  successfully  commercialize  our  products  or  product  candidates  could  be  negatively  affected,  which  would  harm  our  business.  Although  we
currently own all of our patents and our patent applications, similar risks would apply to any patents or patent applications that we may in-license in the
future.

71

We,  or  any  future  partners,  collaborators,  or  licensees,  may  fail  to  identify  patentable  aspects  of  inventions  made  in  the  course  of  development  and
commercialization  activities  before  it  is  too  late  to  obtain  patent  protection  on  them.  Therefore,  we  may  miss  potential  opportunities  to  strengthen  our
patent position.

It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example with
respect  to  proper  priority  claims,  inventorship,  claim  scope,  or  requests  for  patent  term  adjustments.  If  we  or  our  partners,  collaborators,  licensees  or
licensors fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our partners,
collaborators, licensees or licensors are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights,
such  patent  rights  could  be  compromised.  If  there  are  material  defects  in  the  form,  preparation,  prosecution,  or  enforcement  of  our  patents  or  patent
applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes
could impair our ability to prevent competition from third parties, which may have an adverse impact on our business.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain. No consistent policy regarding the breadth of claims
allowed  in  biotechnology  and  pharmaceutical  patents  has  emerged  to  date  in  the  United  States  or  in  many  foreign  jurisdictions.  In  addition,  the
determination  of  patent  rights  with  respect  to  pharmaceutical  compounds  commonly  involves  complex  legal  and  factual  questions,  which  has  in  recent
years  been  the  subject  of  much  litigation.  As  a  result,  the  issuance,  scope,  validity,  enforceability  and  commercial  value  of  our  patent  rights  are  highly
uncertain.

Moreover,  because  the  issuance  of  a  patent  is  not  conclusive  as  to  its  inventorship,  scope,  validity  or  enforceability,  our  patents  or  pending  patent
applications may be challenged in the courts or patent offices in the United States and abroad. There is no assurance that all of the potentially relevant prior
art relating to our patents and patent applications has been found. If such prior art exists, it may be used to invalidate a patent or may prevent a patent from
issuing  from  a  pending  patent  application.  For  example,  such  patent  filings  may  be  subject  to  a  third-party  pre-issuance  submission  of  prior  art  to  the
USPTO and/or to other patent offices around the world. Alternately or additionally, we may become involved in post-grant review procedures, oppositions,
derivations proceedings, reexaminations, inter partes review or interference proceedings, in the United States or elsewhere, challenging patents or patent
applications in which we have rights, including patents on which we rely to protect our business. An adverse determination in any such challenges may
result  in  loss  of  exclusivity  or  in  patent  claims  being  narrowed,  invalidated  or  held  unenforceable,  in  whole  or  in  part,  which  could  limit  our  ability  to
exclude  others  from  using  or  commercializing  similar  or  identical  technology  and  products,  or  may  limit  the  duration  of  the  patent  protection  of  our
technology and products.

Pending and future patent applications may not result in patents being issued which protect our business, in whole or in part, or which effectively prevent
others from commercializing competitive products. Changes in either the patent laws or interpretation of the patent laws in the United States and other
countries may diminish the value of our patents or narrow the scope of our patent protection. In addition, the laws of foreign countries may not protect our
rights to the same extent or in the same manner as the laws of the United States. For example, patent laws in various jurisdictions, including significant
commercial markets such as Europe, restrict the patentability of methods of treatment of the human body more than United States law does.

The  patent  application  process  is  subject  to  numerous  risks  and  uncertainties,  and  there  can  be  no  assurance  that  we  or  any  of  our  future  development
partners will be successful in protecting our product candidates by obtaining, maintaining and defending patents. These risks and uncertainties include the
following:
<

the USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and
other provisions during the patent process. There are situations in which noncompliance can result in abandonment or lapse of a patent or patent
application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter
the market earlier than would otherwise have been the case;
patent applications may not result in any patents being issued;
patents that may be issued may be challenged, invalidated, modified, revoked, circumvented, found to be unenforceable or otherwise may not
provide any competitive advantage;
our  competitors,  many  of  whom  have  substantially  greater  resources  and  many  of  whom  have  made  significant  investments  in  competing
technologies, may seek or may have already obtained patents that will limit, interfere with or eliminate our ability to make, use, and sell our
potential product candidates;
there may be significant pressure on the U.S. government and international governmental bodies to limit the scope of patent protection both
inside  and  outside  the  United  States  for  disease  treatments  that  prove  successful,  as  a  matter  of  public  policy  regarding  worldwide  health
concerns; and
countries  other  than  the  United  States  may  have  patent  laws  less  favorable  to  patentees  than  those  upheld  by  U.S.  courts,  allowing  foreign
competitors a better opportunity to create, develop and market competing product candidates in such countries.

Issued patents that we have or may in the future obtain or license may not provide us with any meaningful protection, prevent competitors from competing
with  us  or  otherwise  provide  us  with  any  competitive  advantage.  Our  competitors  may  be  able  to  circumvent  our  or  our  future  licensors’  patents  by
developing  similar  or  alternative  technologies  or  products  in  a  non-infringing  manner.  Our  competitors  may  also  seek  approval  to  market  their  own
products  similar  to  or  otherwise  competitive  with  our  products.  Alternatively,  our  competitors  may  seek  to  market  generic  versions  of  any  approved
products  by  submitting  ANDAs  to  the  FDA  in  which  they  claim  that  patents  owned  or  in  the  future  licensed  by  us  are  invalid,  unenforceable  or  not
infringed. In these circumstances, we may need to defend or assert our patents, or both, including by filing lawsuits alleging patent infringement. In any of
these types of proceedings, a court or other agency with jurisdiction may find our patents invalid or unenforceable, or that our competitors are competing in
a non-infringing manner. Thus, even if we have valid and enforceable patents, these patents still may not provide protection against competing products or
processes sufficient to achieve our business objectives.

In the future, we may enter into license agreements with third parties pursuant to which they have the right, but not the obligation, in certain circumstances
to control enforcement of our licensed patents or defense of any claims asserting the invalidity of these patents. Even if we are permitted to pursue such
enforcement or defense, we will require the cooperation of those licensors and cannot guarantee that we would receive it and on what terms. We cannot be
certain that those licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our
interests in the licensed patents. If we cannot obtain patent protection or enforce existing or future patents against third parties, our competitive position and
our financial condition could suffer.

In addition, we rely on the protection of our trade secrets and proprietary know-how. Although we take steps to protect our trade secrets and unpatented
know-how, including entering into confidentiality agreements with third parties and confidential information and inventions agreements with employees,
consultants  and  advisors,  we  cannot  provide  any  assurances  that  all  such  agreements  have  been  duly  executed,  and  third  parties  may  still  obtain  this
information  or  may  come  upon  this  or  similar  information  independently.  Additionally,  if  the  steps  taken  to  maintain  our  trade  secrets  are  deemed
inadequate, we may have insufficient recourse against third parties for misappropriating our trade secrets. If any of these events occurs or if we otherwise
lose protection for our trade secrets or proprietary know-how, our business may be harmed.

It is difficult and costly to protect our intellectual property and our proprietary technologies, and we may not be able to ensure their protection.

Our  commercial  success  will  depend  in  part  on  obtaining  and  maintaining  patent  protection  and  trade  secret  protection  for  the  use,  formulation  and
structure of our product candidates, the methods used to manufacture them, the related therapeutic targets and associated methods of treatment as well as on
successfully defending these patents against potential third-party challenges. Our ability to protect our products and product candidates from unauthorized
making, using, selling, offering to sell or importing by third parties is dependent on the extent to which we have rights under valid and enforceable patents
that cover these activities.

The patent positions of pharmaceutical, biotechnology and other life sciences companies can be highly uncertain and involve complex legal and factual
questions for which important legal principles remain unresolved. Changes in either the patent laws or in interpretations of patent laws in the United States
and other countries may diminish the value of our intellectual property. Further, the determination that a patent application or patent claim meets all of the
requirements for patentability is a subjective determination based on the application of law and jurisprudence. The ultimate determination by the USPTO or
by a court or other trier of fact in the United States, or corresponding foreign national patent offices or courts on whether a claim meets all requirements of
patentability cannot be assured. We have not conducted searches for third-party publications, patents and other information that may affect the patentability
of claims in our various patent applications and patents, so we cannot be certain that all relevant information has been identified. Accordingly, we cannot
predict the breadth of claims that may be allowed or enforced in our patent applications and patents, in any future licensed patents or patent applications or
in third-party patents.

We cannot provide assurances that any claim(s) in any of our patent applications will be found to be patentable, including over our own prior art patents, or
that any such patent applications will issue as patents. Neither can we make assurances as to the scope of any claims that may issue from our pending and
future patent applications nor to the outcome of any proceedings instituted by any potential third parties that could challenge the patentability, validity or
enforceability  of  our  patents  and  patent  applications  in  the  United  States  or  foreign  jurisdictions.  Any  such  challenge,  if  successful,  could  limit  patent
protection for our products and product candidates and/or materially harm our business.

73

The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect
our rights or permit us to gain or keep our competitive advantage. For example:

<

<

<

<

we may not be able to generate sufficient data to support full patent applications that protect the entire breadth of developments in one or more
of our programs;
it is possible that one or more of our pending patent applications will not become an issued patent or, if issued, that the patent(s) will not: (a) be
sufficient to protect our technology, (b) provide us with a basis for commercially viable products and/or (c) provide us with any competitive
advantages;
if our pending applications issue as patents, they may be challenged by third parties as not infringed, invalid or unenforceable under U.S. or
foreign laws; or
if issued, the patents under which we hold rights may not be valid or enforceable.

In addition, to the extent that we are unable to obtain and maintain patent protection for one of our products or product candidates or in the event that such
patent protection expires, it may no longer be cost-effective to extend our portfolio by pursuing additional development of a product or product candidate
for follow-on indications.

We also may rely on trade secrets to protect our technologies or products, especially where we do not believe patent protection is appropriate or obtainable.
However,  trade  secrets  are  difficult  to  protect.  Although  we  use  reasonable  efforts  to  protect  our  trade  secrets,  our  employees,  consultants,  contractors,
outside scientific collaborators and other advisers may unintentionally or willfully disclose our information to competitors. Enforcing a claim that a third-
party entity illegally obtained and is using any of our trade secrets is expensive and time consuming, and the outcome is unpredictable. In addition, courts
outside the United States are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge,
methods and know-how.

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

Periodic  maintenance  fees,  renewal  fees,  annuity  fees  and  various  other  governmental  fees  on  patents  and  applications  are  required  to  be  paid  to  the
USPTO and various governmental patent agencies outside the United States in several stages over the lifetime of the patents and applications. The USPTO
and  various  non-U.S.  governmental  patent  agencies  require  compliance  with  a  number  of  procedural,  documentary,  fee  payment  and  other  similar
provisions during the patent application process and after a patent has issued. There are situations in which non-compliance can result in abandonment or
lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction.

Patent terms may be inadequate to protect our competitive position on our products for an adequate amount of time.

Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might
expire before or shortly after such candidates are commercialized. Where available, we will seek extensions of patent terms in the United States and, if
available, in other countries where we are prosecuting patents. In the United States, the Drug Price Competition and Patent Term Restoration Act of 1984
permits a patent term extension of up to five years beyond the normal expiration of the patent, which is limited to the approved indication (or any additional
indications approved during the period of extension). 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.  If  this  occurs,  our  competitors  may  be  able  to  take  advantage  of  our
investment in development and clinical trials by referencing our clinical and preclinical data and launch their product earlier than might otherwise be the
case.

Our unpatented trade secrets, know-how, confidential and proprietary information, and technology may be inadequately protected.

We rely in part on unpatented trade secrets, know-how and technology. This intellectual property is difficult to protect, especially in the pharmaceutical
industry, where much of the information about a product must be submitted to regulatory authorities during the regulatory approval process. We seek to
protect trade secrets, confidential information and proprietary information, in part, by entering into confidentiality and invention assignment agreements
with  employees,  consultants,  and  others.  These  parties  may  breach  or  terminate  these  agreements,  and  we  may  not  have  adequate  remedies  for  such
breaches. Furthermore, these agreements may not provide meaningful protection for our trade secrets or other confidential or proprietary information or
result in the effective assignment to us of intellectual property and may not provide an adequate remedy in the event of unauthorized use or disclosure of
confidential  information  or  other  breaches  of  the  agreements.  Despite  our  efforts  to  protect  our  trade  secrets  and  our  other  confidential  and  proprietary
information, we or our collaboration partners, board members, employees, consultants, contractors, or scientific and other advisors may unintentionally or
willfully disclose our proprietary information to competitors.

74

 
There is a risk that our trade secrets and other confidential and proprietary information could have been, or could, in the future, be shared by any of our
former employees with, and be used to the benefit of, any company that competes with us.

If  we  fail  to  maintain  trade  secret  protection  or  fail  to  protect  the  confidentiality  of  our  other  confidential  and  proprietary  information,  our  competitive
position may be adversely affected. Competitors may also independently discover our trade secrets. Enforcement of claims that a third party has illegally
obtained and is using trade secrets is expensive, time consuming and uncertain. If our competitors independently develop equivalent knowledge, methods
and know-how, we would not be able to assert our trade secret protections against them, which could have a material adverse effect on our business.

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

Our trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We rely on
both registration and common law protection for our trademarks. We may not be able to protect our rights to these trademarks and trade names or may be
forced to stop using these names, which we need for name recognition by potential partners or customers in our markets of interest. During the trademark
registration  process,  we  may  receive  Office  Actions  from  the  USPTO  objecting  to  the  registration  of  our  trademark.  Although  we  would  be  given  an
opportunity to respond to those objections, we may be unable to overcome such rejections. In addition, in the USPTO and in comparable agencies in many
foreign  jurisdictions,  third  parties  are  given  an  opportunity  to  oppose  pending  trademark  applications  and/or  to  seek  the  cancellation  of  registered
trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. If we are
unable  to  establish  name  recognition  based  on  our  trademarks  and  trade  names,  we  may  not  be  able  to  compete  effectively  and  our  business  may  be
adversely affected.

Risks Related to Intellectual Property Litigation

Others may challenge inventorship or claim an ownership interest in our intellectual property which could expose it to litigation and have a significant
adverse effect on its prospects.

A third party or former employee or collaborator may claim an ownership interest in one or more of our patents or other proprietary or intellectual property
rights. A third party could bring legal actions against us and seek monetary damages and/or enjoin clinical testing, manufacturing and marketing of the
affected product or products. While we are presently unaware of any claims or assertions by third parties with respect to our patents or other intellectual
property, we cannot guarantee that a third party will not assert a claim or an interest in any of such patents or intellectual property. If we become involved
in  any  litigation,  it  could  consume  a  substantial  portion  of  our  resources  and  cause  a  significant  diversion  of  effort  by  our  technical  and  management
personnel.

Others may claim an ownership interest in our intellectual property which could expose us to litigation and have a significant adverse effect on our
prospects.

A third party may claim an ownership interest in one or more of our patents or other proprietary or intellectual property rights. A third party could bring
legal actions against us and seek monetary damages and/or enjoin clinical testing, manufacturing and marketing of the affected product or products. While
we are presently unaware of any claims or assertions by third parties with respect to our patents or other intellectual property, we cannot guarantee that a
third party will not assert a claim or an interest in any of such patents or intellectual property. If we become involved in any litigation, it could consume a
substantial  portion  of  our  resources  and  cause  a  significant  diversion  of  effort  by  our  technical  and  management  personnel.  If  any  of  these  actions  are
successful, in addition to any potential liability for damages, we could be required to obtain a license to continue to manufacture or market the affected
product, in which case we may be required to pay substantial royalties or grant cross-licenses to our patents. We cannot, however, assure you that any such
license will be available on acceptable terms, if at all. Ultimately, we could be prevented from commercializing a product candidate or be forced to cease
some aspect of our business operations as a result of claims of patent infringement or violation of other intellectual property rights. Further, the outcome of
intellectual  property  litigation  is  subject  to  uncertainties  that  cannot  be  adequately  quantified  in  advance,  including  the  demeanor  and  credibility  of
witnesses and the identity of any adverse party. This is especially true in intellectual property cases that may turn on the testimony of experts as to technical
facts upon which experts may reasonably disagree.

The pharmaceutical industry is characterized by frequent patent litigation, and we could become subject to litigation that could be costly, result in the
diversion of management’s time and efforts, require us to pay damages or prevent us from marketing our existing or future products.

Our commercial success will depend in part on not infringing the patents or violating the proprietary rights of third parties. Significant litigation regarding
patent rights exists in our industry. Our competitors in both the United States and abroad, many of which have

75

substantially greater resources and have made substantial investments in competing technologies, may have applied for or obtained or may in the future
apply for and obtain patents that will prevent, limit or otherwise interfere with our ability to make and sell our products. Generally, we do not conduct
independent  reviews  of  patents  issued  to  third  parties.  The  large  number  of  patents,  the  rapid  rate  of  new  patent  issuances,  the  complexities  of  the
technology involved, and uncertainty of litigation increase the risk of business assets and management’s attention being diverted to patent litigation. In the
future,  we  may  receive  communications  from  various  industry  participants  alleging  our  infringement  of  their  patents,  trade  secrets,  or  other  intellectual
property rights and/or offering licenses to such intellectual property. Any lawsuits resulting from such allegations could subject us to significant liability for
damages and invalidate our proprietary rights. Any potential intellectual property litigation also could force us to do one or more of the following:

  <
<

<

<

<

<

  stop selling products or using technology that contains the allegedly infringing intellectual property;

lose the opportunity to license our technology to others or to collect royalty payments based upon successful protection and assertion of our
intellectual property rights against others;
incur significant legal expenses;
pay substantial damages to the party whose intellectual property rights we may be found to be infringing;
redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive and/or infeasible; or
attempt to obtain a license to the relevant intellectual property from third parties, which may not be available on reasonable terms or at all.

Any litigation or claim against us, even those without merit, may cause us to incur substantial costs and could place a significant strain on our financial
resources, divert the attention of management from our core business, and harm our reputation. In connection with such litigation or claims, we may be
required to obtain licenses or make changes to our products or technologies, and if we fail to do so, we may have to withdraw existing products from the
market  or  may  be  unable  to  commercialize  one  or  more  of  our  products,  all  of  which  could  have  a  material  adverse  effect  on  our  business,  results  of
operations and financial condition.

We  may  be  subject  to  damages  resulting  from  claims  that  we  or  our  employees  have  wrongfully  used  or  disclosed  alleged  trade  secrets  of  our
competitors or are in breach of non-competition or non-solicitation agreements with our competitors.

Many of our employees were previously employed at other pharmaceutical companies, including our competitors or potential competitors, in some cases
until recently. We may be subject to claims that we or our employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary
information of these former employers or competitors. In addition, we have been and may in the future be subject to claims that we caused an employee to
breach the terms of his or her non-competition or non-solicitation agreement. Litigation may be necessary to defend against these claims. Even if we are
successful in defending against these claims, litigation could result in substantial costs and could be a distraction to management. If our defense to those
claims fails, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Any litigation or the threat thereof
may adversely affect our ability to hire employees. A loss of key personnel or their work product could hamper or prevent our ability to commercialize our
products and product candidates, which could have an adverse effect on our business, results of operations and financial condition.

An NDA submitted under Section 505(b)(2) subjects us to the risk that we may be subject to a patent infringement lawsuit that would delay or prevent
the review or approval of our product candidates.

We expect to submit NDAs under Section 505(b)(2) of the FDCA for our product candidates. Section 505(b)(2) permits the submission of an NDA where
at least some of the information required for approval comes from preclinical studies and/or clinical trials that were not conducted by, or for, the applicant
and for which the applicant has not obtained a right of reference. An NDA under Section 505(b)(2) would enable us to reference published literature and/or
the FDA’s previous findings of safety and effectiveness for a previously approved drug.

For NDAs submitted under Section 505(b)(2), the patent certification and related provisions of the Hatch-Waxman Act apply. Accordingly, if we rely for
approval  on  the  safety  or  effectiveness  information  for  a  previously  approved  drug,  referred  to  as  a  listed  drug,  we  will  be  required  to  include  patent
certifications in our 505(b)(2) application regarding any patents covering the listed drug. If there are patents listed in the FDA publication Approved Drug
Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book, for the listed drug, and we seek to obtain approval prior to the
expiration of one or more of those patents, we will be required to submit a Paragraph IV certification indicating our belief that the relevant patents are
invalid or unenforceable or will not be infringed by the manufacture, use or sale of the product that is the subject of our 505(b)(2) application. Otherwise,
our 505(b)(2) application cannot be approved by the FDA until the expiration of any patents listed in the Orange Book for the listed drug. While we did not
submit any Paragraph IV certifications in connection with our 505(b)(2) NDA for Gvoke, and do not expect to submit any

76

Paragraph  IV  certifications  for  our  other  current  product  candidates,  there  can  be  no  assurance  that  we  will  not  be  required  to  submit  a  Paragraph  IV
certification in respect of any future product candidates for which we seek approval under Section 505(b)(2).

If we submit any Paragraph IV certification that may be required, we will be required to provide notice of that certification to the NDA holder and patent
owner shortly after our 505(b)(2) application is accepted for filing. Under the Hatch-Waxman Act, the patent owner may file a patent infringement lawsuit
after receiving such notice. If a patent infringement lawsuit is filed within 45 days of the patent owner’s or NDA holder’s receipt of notice (whichever is
later),  a  one-time,  automatic  stay  of  the  FDA’s  ability  to  approve  the  505(b)(2)  NDA  is  triggered,  which  typically  extends  for  30  months  unless  patent
litigation is resolved in favor of the Paragraph IV filer or the patent expires before that time. Accordingly, we may invest a significant amount of time and
expense in the development of one or more product candidates only to be subject to significant delay and patent litigation before such product candidates
may be commercialized, if at all.

In addition, a 505(b)(2) application will not be approved until any non-patent exclusivity listed in the Orange Book for the listed drug, or for any other drug
with the same protected conditions of approval as our product, has expired. The FDA also may require us to perform one or more additional clinical trials
or measurements to support the change from the listed drug, which could be time consuming and could substantially delay our achievement of regulatory
approval. The FDA also may reject any future 505(b)(2) submissions and require us to submit traditional NDAs under Section 505(b)(1), which would
require extensive data to establish safety and effectiveness of the product for the proposed use and could cause delay and additional costs. In addition, the
FDA  could  reject  any  future  505(b)(2)  application  and  require  us  to  submit  an  ANDA  if,  before  the  submission  of  our  505(b)(2)  application,  the  FDA
approves an application for a product that is pharmaceutically equivalent to ours. These factors, among others, may limit our ability to commercialize our
product candidates successfully.

Risks Related to Intellectual Property Laws

Changes to the patent law in the United States and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to
protect our products.

As  is  the  case  with  other  biopharmaceutical  companies,  our  success  is  heavily  dependent  on  intellectual  property,  particularly  patents.  Obtaining  and
enforcing  patents  in  the  biopharmaceutical  industry  involve  both  technological  and  legal  complexity  and  are  therefore  costly,  time  consuming  and
inherently uncertain. Patent reform legislation in the United States, including the Leahy-Smith America Invents Act ("America Invents Act") signed into
law in September 2011, could increase those uncertainties and costs. The America Invents Act includes a number of significant changes to U.S. patent law,
including provisions that affect the way patent applications are prosecuted, redefining prior art and providing more efficient and cost-effective avenues for
competitors to challenge the validity of patents. In addition, the America Invents Act has reformed the United States patent law in part by changing the U.S.
patent system from a “first to invent” system to a “first inventor to file” system. The first inventor to file provision, however, only became effective on
March 16, 2013, so it is still not yet clear what, if any, impact the America Invents Act will have on the operations of our business. The America Invents
Act and its implementation could make it more difficult to obtain patent protection for our inventions and increase the uncertainties and costs surrounding
the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could harm our business, results of operations
and financial condition.

Further, the America Invents Act created new procedures to challenge the validity of issued patents in the United States, including post-grant review and
inter partes review proceedings, which some third parties have been using to cause the cancellation of selected or all claims of issued patents. For a patent
with an effective filing date of March 16, 2013 or later, a petition for post-grant review can be filed by a third party in a nine-month window from issuance
of the patent. A petition for inter partes review can be filed immediately following the issuance of a patent if the patent has an effective filing date prior to
March 16, 2013. A petition for inter partes review can be filed after the nine-month period for filing a post-grant review petition has expired for a patent
with an effective filing date of March 16, 2013 or later. Post-grant review proceedings can be brought on any ground of invalidity, whereas inter partes
review proceedings can only raise an invalidity challenge based on published prior art and patents. In these adversarial actions, the USPTO reviews patent
claims  without  the  presumption  of  validity  afforded  to  U.S.  patents  in  lawsuits  in  U.S.  federal  courts  and  uses  a  lower  burden  of  proof  than  used  in
litigation in U.S. federal courts. Therefore, it is generally considered easier and less costly for a competitor or third party to have a U.S. patent invalidated
in a USPTO post-grant review or inter partes review proceeding than invalidated in a litigation in a U.S. federal court. If any of our patents are challenged
by a third party in such a USPTO proceeding, there is no guarantee that we will be successful in defending the patent, which would result in a loss of the
challenged patent right to us. Depending on future actions by the U.S. Congress, the U.S. courts, the USPTO and the relevant law-making bodies in other
countries, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce
our existing patents and patents that we might obtain in the future.

77

Risks Related to Enforcement of Intellectual Property Rights

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

Filing, prosecuting, enforcing and defending patents on our product 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.  The  requirements  for
patentability may differ in certain countries, particularly in developing countries; thus, even in countries where we do pursue patent protection, there can be
no assurance that any patents will issue with claims that cover our product candidates.

Moreover,  our  ability  to  protect  and  enforce  our  intellectual  property  rights  may  be  adversely  affected  by  unforeseen  changes  in  foreign  intellectual
property laws. Additionally, laws of some countries outside the United States and Europe do not afford intellectual property protection to the same extent as
the laws of the United States and Europe. Many companies have encountered significant problems in protecting and defending intellectual property rights
in certain foreign jurisdictions. The legal systems of some countries, including India, China and other developing countries, do not favor the enforcement of
patents and other intellectual property rights. This could make it difficult for us to stop the infringement of our patents or the misappropriation of our other
intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third
parties. Consequently, we may not be able to prevent third parties from practicing our inventions in certain countries outside the United States and Europe.
Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop and market their own products and, further,
may export otherwise infringing products to territories where we have patent protection, if our ability to enforce our patents to stop infringing activities is
inadequate.  These  products  may  compete  with  our  products,  and  our  patents  or  other  intellectual  property  rights  may  not  be  effective  or  sufficient  to
prevent them from competing.

Agreements through which we may license patent rights may not give us sufficient rights to permit us to pursue enforcement of those licensed patents or
defense  of  any  claims  asserting  the  invalidity  of  these  patents  or  the  ability  to  control  enforcement  or  defense  of  such  patent  rights  in  all  relevant
jurisdictions as requirements may vary.

Proceedings  to  enforce  our  patent  rights  in  foreign  jurisdictions,  whether  or  not  successful,  could  result  in  substantial  costs  and  divert  our  efforts  and
resources from other aspects of our business. Moreover, such proceedings 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. Furthermore, while we intend to protect our intellectual property
rights in major markets for our products, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may
wish to market our products. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate.

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

Competitors  may  infringe  our  patents,  trademarks,  copyrights  or  other  intellectual  property.  To  counter  infringement  or  unauthorized  use,  we  may  be
required  to  file  infringement  lawsuits,  which  can  be  expensive  and  time  consuming  and  divert  the  time  and  attention  of  our  management  and  scientific
personnel. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their
patents, in addition to counterclaims asserting that our patents are invalid or unenforceable, or both. In any patent infringement proceeding, there is a risk
that a court will decide that a patent of ours is invalid or unenforceable, in whole or in part, and that we do not have the right to exclude the other party
from  making,  using  or  selling  the  invention  at  issue.  There  is  also  a  risk  that,  even  if  the  validity  of  such  patents  is  upheld,  the  court  will  construe  the
patent’s  claims  narrowly  or  decide  that  we  do  not  have  the  right  to  exclude  the  other  party  from  making,  using  or  selling  the  invention  at  issue  on  the
grounds  that  our  patent  claims  do  not  cover  the  invention  or  the  other  party's  manufacture,  use  or  sale  of  it.  An  adverse  outcome  in  a  litigation  or
proceeding involving one or more of our patents could limit our ability to assert those patents against those parties or other competitors and may curtail or
preclude our ability to exclude third parties from making and selling similar or competitive products. Similarly, if we assert trademark infringement claims,
a court may determine that the marks we have asserted are unenforceable, that the alleged infringing mark does not infringe our trademark rights, or that
the party against whom we have asserted trademark infringement has superior rights to the marks in question. In this last instance, we could ultimately be
forced to cease use of such trademarks.

Even  if  we  establish  infringement,  the  court  may  decide  not  to  grant  an  injunction  against  further  infringing  activity  and  instead  award  only  monetary
damages,  which  may  or  may  not  be  an  adequate  remedy.  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 litigation. There could
also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive
these  results  to  be  negative,  it  could  adversely  affect  the  price  of  shares  of  our  common  stock.  Moreover,  there  can  be  no  assurance  that  we  will  have
sufficient financial or other resources

78

to  file  and  pursue  such  infringement  claims,  which  typically  last  for  years  before  they  are  concluded.  Even  if  we  ultimately  prevail  in  such  claims,  the
monetary cost of such litigation and the diversion of the attention of our management and scientific personnel could outweigh any benefit we receive as a
result of the proceedings.

Risks Related to Employee Matters, Managing Growth and Ongoing Operations

Risks Related to Ongoing Operations

If product liability lawsuits are brought against us, our business may be harmed, and we may be required to pay damages that exceed our insurance
coverage.

We may face liability claims related to the use or misuse of our products and product candidates. These claims may be expensive to defend and may result
in large judgments against us. During the course of treatment, patients using our products and product candidates could suffer adverse medical effects for
reasons that may or may not be related to our products and product candidates. Our products which are commercialized face greater risks and therefore, our
risk will increase upon any commercialization by us of our product candidates. Any of these events could result in a claim of liability. Any such claims
against  us,  regardless  of  their  merit,  could  result  in  significant  costs  to  defend  or  awards  against  us  that  could  materially  harm  our  business,  financial
condition or results of operations. In addition, any such claims against us could result in a distraction to management, decreased demand for our products,
an adverse effect on our public reputation, and/or difficulties in commercializing our products. To date, we have not received notice of any product liability
claims against us. We maintain total product liability insurance coverage of $15.0 million.

Although we maintain product liability insurance for claims arising from the use of our products after FDA approval and for claims arising from the use of
our  product  candidates  in  clinical  trials  prior  to  FDA  approval  at  levels  that  we  believe  are  appropriate,  we  may  not  be  able  to  maintain  our  existing
insurance coverage or obtain additional coverage on commercially reasonable terms for the use of our other products and product candidates in the future.
Also,  our  insurance  coverage  and  resources  may  not  be  sufficient  to  satisfy  any  liability  resulting  from  product  liability  claims,  which  could  materially
harm our business, financial condition or results of operations.

Product  liability  claims  could  result  in  an  FDA  or  other  regulatory  authority  investigation  of  the  safety  or  efficacy  of  our  products,  our  manufacturing
processes and facilities, our marketing programs, our internal safety reporting systems or our staff conduct. A regulatory authority investigation could also
potentially lead to a recall of our products or more serious enforcement actions, limitations on the indications for which they may be used, or suspension or
withdrawal of approval. Product liability claims could also result in investigation, prosecution or enforcement action by the DOJ or other federal or state
government agencies.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or
prevent  fraud.  As  a  result,  stockholders  could  lose  confidence  in  our  financial  and  other  public  reporting,  which  would  harm  our  business  and  the
trading price of our common stock.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls
and  procedures,  are  designed  to  prevent  fraud.  Any  failure  to  implement  required  new  or  improved  controls,  or  difficulties  encountered  in  their
implementation could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404 of the
Sarbanes-Oxley Act, or any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over
financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify
other  areas  for  further  attention  or  improvement.  Inferior  internal  controls  could  also  cause  investors  to  lose  confidence  in  our  reported  financial
information, which could have a negative effect on the trading price of our stock.

We  are  required  to  disclose  changes  made  in  our  internal  controls  and  procedures  on  a  quarterly  basis,  and  our  management  is  required  to  assess  the
effectiveness of these controls annually. However, for as long as we are an “emerging growth company” under the Jumpstart Our Business Startups Act
("JOBS Act") enacted in April 2012, our independent registered public accounting firm will not be required to attest to the effectiveness of our internal
controls over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act. We could be an “emerging growth company” for up to five years from
the  date  of  our  IPO.  An  independent  assessment  of  the  effectiveness  of  our  internal  controls  over  financial  reporting  could  detect  problems  that  our
management's  assessment  might  not.  Undetected  material  weaknesses  in  our  internal  controls  over  financial  reporting  could  lead  to  financial  statement
restatements and require us to incur the expense of remediation.

Fluctuations in insurance cost and availability could adversely affect our profitability or our risk management profile.

We  hold  a  number  of  insurance  policies,  including  product  liability  insurance,  directors’  and  officers’  liability  insurance,  general  liability  insurance,
property insurance and workers’ compensation insurance and such policies contain customary conditions and

79

exclusions. If the costs of maintaining adequate insurance coverage increase significantly in the future, our operating results could be materially adversely
affected. Likewise, if any of our current insurance coverage should become unavailable to us or become economically impractical, we would be required to
operate our business without indemnity from commercial insurance providers. Additionally, even if we maintain insurance coverage for a type of liability, a
particular claim may not be covered if it is subject to a coverage exclusion or we do not otherwise meet the conditions for coverage. If we operate our
business without insurance, or with inadequate insurance, we could be responsible for paying claims or judgments against us, which could adversely affect
our results of operations or financial condition.

Laws  and  regulations  governing  international  operations  may  preclude  us  from  developing,  manufacturing  and  selling  certain  products  outside  the
United States or require us to develop and implement costly compliance programs.

We have conducted some clinical trials in international countries. For any operations outside the United States, we must comply with numerous laws and
regulations in each jurisdiction in which we operate. The FCPA prohibits any U.S. individual or business from paying, offering, authorizing payment or
offering anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the
foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed
in the United States to comply with certain accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all
transactions  of  the  corporation,  including  international  subsidiaries,  and  to  devise  and  maintain  an  adequate  system  of  internal  accounting  controls  for
international operations.

Compliance with the FCPA is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, the FCPA presents
particular challenges in the pharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and other hospital
employees  are  considered  foreign  officials.  Certain  payments  to  hospitals  in  connection  with  clinical  trials  and  other  work  have  been  deemed  to  be
improper payments to government officials and have led to FCPA enforcement actions.

Various  laws,  regulations  and  executive  orders  also  restrict  the  use  and  dissemination  outside  the  United  States,  or  the  sharing  with  certain  non-U.S.
nationals, of information classified for national security purposes, as well as certain products and technical data relating to those products. If we expand our
presence  outside  the  United  States,  it  will  require  us  to  dedicate  additional  resources  to  comply  with  these  laws,  and  these  laws  may  preclude  us  from
developing,  manufacturing,  or  selling  certain  products  and  product  candidates  outside  the  United  States,  which  could  limit  our  growth  potential  and
increase our development costs.

The  failure  to  comply  with  laws  governing  international  business  practices  may  result  in  substantial  civil  and  criminal  penalties  and  suspension  or
debarment from government contracting. The SEC also may suspend or bar issuers from trading securities on U.S. exchanges for violations of the FCPA’s
accounting provisions.

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

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

Disruptions  at  the  FDA  and  other  agencies  may  also  slow  the  time  necessary  for  new  drugs  to  be  reviewed  and/or  approved  by  necessary  government
agencies, which would adversely affect our business. For example, over the last several years the U.S. government has shut down several times and certain
regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities.
Separately,  in  response  to  the  COVID-19  pandemic,  on  March  10,  2020  the  FDA  announced  its  intention  to  postpone  most  inspections  of  foreign
manufacturing  facilities  while  local,  national  and  international  conditions  warrant.  On  March  18,  2020,  the  FDA  announced  its  intention  to  temporarily
postpone  routine  surveillance  inspections  of  domestic  manufacturing  facilities  and  provided  guidance  regarding  the  conduct  of  clinical  trials  which  the
FDA continues to update. As of June 23, 2020, the FDA noted it was conducting mission critical domestic and foreign inspections to ensure compliance of
manufacturing facilities with FDA quality standards. On July 10, 2020, the FDA announced its goal of restarting domestic on-site inspections during the
week of July 20, 2020, but such activities will depend on data about the virus’ trajectory in a given state and locality and the rules and guidelines that are
put  in  place  by  state  and  local  governments.  The  FDA  has  developed  a  rating  system  to  assist  in  determining  when  and  where  it  is  safest  to  conduct
prioritized  domestic  inspections.  Should  FDA  determine  that  an  inspection  is  necessary  for  approval  and  an  inspection  cannot  be  completed  during  the
review cycle due to restrictions on

80

travel, FDA has stated that it generally intends to issue a complete response letter. Further, if there is inadequate information to make a determination on the
acceptability of a facility, FDA may defer action on the application until an inspection can be completed. In 2020, several companies announced receipt of
complete response letters due to the FDA's inability to complete required inspections for their applications. Regulatory authorities outside the U.S. may
adopt similar restrictions or other policy measures in response to the COVID-19 pandemic and may experience delays in their regulatory activities. If a
prolonged government shutdown occurs, or if global health concerns continue to prevent the FDA or other regulatory authorities from conducting their
regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA to timely review and process our regulatory
submissions, which could have a material adverse effect on our business. Further, in our operations as a public company, future government shutdowns
could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Risks Related to Employment Matters

Our  business  could  suffer  if  we  lose  the  services  of  key  members  of  our  senior  management  or  if  we  are  not  able  to  attract  and  retain  other  key
employees and consultants.

We  are  dependent  upon  the  continued  services  of  key  members  of  our  executive  management  and  a  limited  number  of  key  advisors  and  personnel.  In
particular, we are highly dependent on the skills and leadership of our executive management team, including Paul Edick, our Chief Executive Officer,
Barry  Deutsch,  our  Chief  Financial  Officer,  Steven  Prestrelski,  our  Chief  Scientific  Officer  and  Co-Founder,  John  Shannon,  our  President  and  Chief
Operating Officer, Ken Johnson, our Senior Vice President, Clinical Development, Regulatory, Quality Assurance and Medical Affairs, and Beth Hecht,
our Senior Vice President, General Counsel and Corporate Secretary. The loss of any one of these individuals could disrupt our operations or our strategic
plans.  Our  industry  has  experienced  a  high  rate  of  turnover  of  management  personnel  in  recent  years.  Any  of  our  personnel  may  terminate  their
employment at will. If we lose one or more of our executive officers or other key employees, our ability to implement our business strategy successfully
could be seriously harmed. Furthermore, replacing executive officers or other 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 develop, gain marketing approval of and
commercialize products successfully.

Additionally, our future success will depend on, among other things, our ability to continue to hire and retain the necessary qualified scientific, technical
and managerial personnel, for whom we compete with numerous other companies, academic institutions and organizations. Competition to hire from this
limited pool is intense, and we may be unable to hire, train, retain or motivate these additional key employees 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.

We  rely  on  consultants  and  advisors,  including  scientific  and  clinical  advisors,  to  assist  us  in  formulating  our  research  and  development  and
commercialization  strategy.  Our  consultants  and  advisors  may  be  employed  by  other  entities  and  may  have  commitments  under  consulting  or  advisory
contracts with those entities that may limit their availability to us. If we are unable to continue to attract and retain highly qualified personnel, our ability to
develop and commercialize our product candidates will be limited.

Our employees, independent contractors, consultants, collaborators and contract research organizations may engage in misconduct or other improper
activities,  including  non-compliance  with  regulatory  standards  and  requirements,  which  could  cause  significant  liability  for  us  and  harm  to  our
reputation.

We are exposed to the risk that our employees, independent contractors, consultants, collaborators and contract research organizations may engage in fraud
or other misconduct, including intentional failures to comply with FDA regulations or similar regulations of comparable non-U.S. regulatory authorities, to
provide accurate information to the FDA or comparable non-U.S. regulatory authorities, to comply with manufacturing standards we have established, to
comply with federal and state healthcare fraud and abuse laws and regulations and similar laws and regulations established and enforced by comparable
non-U.S. regulatory authorities, to report financial information or data accurately or to disclose unauthorized activities to us. Such misconduct could also
involve the improper use or misrepresentation of information obtained in the course of clinical trials, creating fraudulent data in our preclinical studies or
clinical trials or illegal misappropriation of product materials, which could result in regulatory sanctions and serious harm to our reputation. 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, standards or regulations. Additionally, we are subject to the risk that a person or government could allege such fraud or other misconduct,
even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those

81

actions could have a significant impact on our business and results of operations, including the imposition of significant fines or other sanctions.

Risks Related to Managing Growth

We may need to increase the size of our organization, and we may encounter difficulties managing our growth.

As of December 31, 2020, we had 180 employees. As we commercialize Gvoke and development of our product candidates continues to progress, we may
need to hire additional employees as required to add depth and specialized expertise to our team. This growth could place a strain on our administrative and
operational infrastructure. If the product candidates that we are developing continue to advance in clinical trials, we will need to expand our development,
regulatory,  manufacturing,  quality,  compliance,  recordkeeping,  information  technology,  training,  marketing  and  sales  capabilities  or  contract  with  third
parties  to  provide  these  capabilities  for  us.  As  our  operations  expand,  we  expect  that  we  will  need  to  develop  additional  relationships  with  various
collaborators, CROs, suppliers, manufacturers and other organizations. We may not be able to establish such relationships or may incur significant costs to
do so. Our ability to manage our growth will also require us to continue to improve our operational, financial and management controls, reporting systems
and procedures, and other compliance programs and processes, which will further increase our operating costs. Failure to manage our growth effectively
could  cause  us  to  over-invest  or  under-invest  in  infrastructure  and  result  in  losses  or  weaknesses  in  our  infrastructure,  which  could  adversely  affect  us.
Additionally,  our  anticipated  growth  will  increase  the  demands  placed  on  our  suppliers,  resulting  in  an  increased  need  for  us  to  monitor  our  suppliers
carefully for quality assurance, and our business could suffer.

We may be required to maintain high levels of inventory, which could consume a significant amount of our resources and reduce our cash flows.

As a result of the need to maintain substantial levels of inventory due to single third-party sourcing and long lead-times to develop alternate third-party
sources,  we  intend  where  feasible  to  carry  a  high  level  of  inventory  for  strategic  materials  and  products  and  are  subject  to  the  risk  of  inventory
obsolescence. In the event that a substantial portion of our inventory becomes obsolete, it could have a material adverse effect on our earnings and cash
flows due to the resulting costs associated with the inventory impairment charges and costs required to replace such inventory.

We  may  seek  to  grow  our  business  through  acquisitions  of  or  investments  in  new  or  complementary  businesses,  products  or  technologies,  and  the
failure to manage any acquisitions or investments, or the failure to integrate them with our existing business, could have a material adverse effect on
us.

From time to time we expect to consider opportunities to acquire or make investments in other technologies, products and businesses that may enhance our
capabilities,  complement  our  current  products  or  expand  the  breadth  of  our  markets  or  customer  base.  Potential  acquisitions  and  strategic  investments
involve numerous risks, including:

<

<

<

<

<

<

<

<

  problems assimilating the purchased technologies, products or business operations;

issues establishing and maintaining uniform standards, procedures, controls and policies;
unanticipated costs associated with acquisitions;
diversion of management’s attention from our core business;
adverse effects on existing business relationships with suppliers and customers;
risks associated with entering new markets in which we have limited or no experience;
potential loss of key employees of acquired businesses; and
increased legal and accounting compliance costs.

We have no current commitments with respect to any acquisition or investment, and we have never entered into or completed an acquisition. We do not
know if we will be able to identify suitable acquisitions, complete any such acquisitions on favorable terms or at all, successfully integrate any acquired
business,  product  or  technology  into  our  business  or  retain  any  key  personnel,  suppliers  or  distributors.  Our  ability  to  grow  through  acquisitions
successfully depends upon our ability to identify, negotiate, complete and integrate suitable target businesses and to obtain any necessary financing. These
efforts could be expensive and time consuming and may disrupt our ongoing business and prevent management from focusing on our operations. If we are
unable  to  integrate  any  acquired  businesses,  products  or  technologies  effectively,  our  business,  results  of  operations  and  financial  condition  could  be
materially adversely affected.

Risks Related to Our Common Stock

Risks Related to Investment in Securities

Our stock price has been and will likely continue to be volatile, and you may not be able to resell shares of our common stock at or above the price you
paid.

The trading price of our common stock historically has been highly volatile and could continue to be subject to large fluctuations in response to the risk
factors discussed in this section, and others beyond our control, including:

<

<

<

<

<

<

regulatory actions with respect to our competitors’ products and product candidates;
the success of existing or new competitive products or technologies;
results of clinical trials of product candidates of our competitors;
announcements  by  us  or  our  competitors  of  significant  acquisitions,  strategic  partnerships,  joint  ventures,  collaborations  or  capital
commitments;
the timing and results of clinical trials of our pipeline product candidates;
commencement or termination of collaborations for our development programs;

changes in estimates or recommendations by securities analysts, if any, that cover our stock;
changes in the structure of healthcare payment systems;

<
< market conditions in the pharmaceutical and biotechnology sectors;
<

general economic, industry and market conditions;
global health concerns, such as the COVID-19 pandemic; and
the other factors described in this “Risk Factors” section.

<

<

In recent years, the stock markets, and particularly the stock of smaller pharmaceutical and biotechnology companies, at times have experienced price and
volume  fluctuations  that  have  often  been  unrelated  or  disproportionate  to  the  operating  performance  of  affected  companies.  Broad  market  and  industry
factors may significantly affect the market price of our common stock unrelated to our actual operating performance. Since shares of our common stock
were sold in our IPO in June 2018 at a price of $15.00 per share, our stock price has fluctuated significantly.

In addition, in the past, class action litigation has often been instituted against companies whose securities have experienced periods of volatility in market
price. Securities litigation brought against us following volatility in our stock price, regardless of the merit or ultimate results of such litigation, could result
in substantial costs, which would hurt our financial condition and operating results and divert management’s attention and resources from our business.

Risks Related to Future Financial Condition

The conversion of any of the Convertible Notes into shares of common stock could have a dilutive effect that could cause our share price to go down.

The Convertible Notes are convertible into shares of common stock at any time at the option of the holder subject to certain conditions. We have reserved a
sufficient number of shares of common stock for issuance upon conversion of the Convertible Notes.

83

 
 
During the second half of 2020, $39.1 million in principal amount of Convertible Notes were converted into 13,171,791 shares of the Company’s common
stock. As of February 28, 2021, the outstanding balance of Convertible Notes was $47.2 million. If any more or all of the Convertible Notes are converted
into shares of common stock, our existing shareholders will experience immediate dilution of voting rights and the price of shares of our common stock
may decline. Furthermore, the perception that such dilution could occur may cause the market price of our common stock to decline. At any time before the
close of business on the second scheduled trading day immediately before the maturity date, holders of Convertible Notes may convert their Convertible
Notes at their option into shares of our common stock, together, if applicable, with cash in lieu of any fractional share, at the then-applicable conversion
rate.  The  conversion  rate  for  the  Convertible  Notes  will  initially  be  326.7974  shares  of  our  common  stock  per  $1,000  principal  amount  of  Convertible
Notes, which represents an initial conversion price of approximately $3.06 per share of common stock, and is subject to adjustment under the terms of the
Convertible Notes. In the event of certain circumstances, we will increase the conversion rate, provided that the conversion rate will not exceed 367.6470
shares of our common stock per $1,000 principal amount of Convertible Notes. Because the conversion rates of the Convertible Notes adjust upward upon
the occurrence of certain events, our existing shareholders may experience more dilution if any or all of the Convertible Notes are converted into shares of
common stock after the adjusted conversion rate became effective.

We  do  not  anticipate  paying  any  cash  dividends  in  the  foreseeable  future,  and  accordingly,  our  stockholders’  ability  to  achieve  a  return  on  their
investment will depend on appreciation in the price of our common stock.

We  do  not  anticipate  declaring  any  cash  dividends  to  holders  of  our  common  stock  in  the  foreseeable  future.  In  addition,  under  our  Amended  Loan
Agreement, we are restricted from paying any dividends or making any distributions on account of our capital stock. Our ability to pay cash dividends also
may be prohibited by future loan agreements. Consequently, investors must rely on sales of their common stock after price appreciation, which may never
occur, as the only way to realize any future gains on their investment. Investors seeking cash dividends should not invest in our common stock.

Risks Related to Tax

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,  2020,  we  had  federal  net  operating  loss  carryforwards  of  $284.8  million  and  various  state  net  operating  loss  carryforwards  of
$220.6 million. If not utilized, the federal net operating losses generated in taxable years beginning on or before December 31, 2017 will expire at various
dates between 2025 and 2037, and these net operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities.
Federal net operating losses generated in taxable years beginning after December 31, 2017 can be carried forward indefinitely; however, such net operating
losses may only offset up to 80% of taxable income in taxable years beginning after December 31, 2020. As of December 31, 2020, we had $8.0 million
and  $1.7  million  of  federal  and  state  income  tax  credits,  respectively,  to  reduce  future  tax  liabilities.  If  not  utilized,  these  carryforwards  will  expire  at
various dates between 2025 and 2038, and these tax credit carryforwards could expire unused and be unavailable to offset future income tax liabilities. In
addition,  under  Sections  382  and  383  of  the  Internal  Revenue  Code  of  1986,  as  amended  ("Code")  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.  Our  existing  net  operating  losses  or  credits  may  be  subject  to  limitations  arising  from  previous  ownership  changes,  and  if  we  undergo
future ownership changes, many of which may be outside of our control, our ability to utilize our net operating losses or credits could be further limited by
Sections 382 and 383 of the Code. Accordingly, we may not be able to utilize a material portion of our net operating losses or credits.

Changes in tax law may adversely affect us or our investors.

The rules dealing with U.S. federal, state and local income taxation are constantly under review by persons involved in the legislative process and by the
Internal  Revenue  Service  ("IRS")  and  the  U.S.  Treasury  Department.  Changes  to  tax  laws  (which  changes  may  have  retroactive  application)  could
adversely affect us or holders of our common stock. In recent years, many such changes have been made, and changes are likely to continue to occur in the
future. For example, on March 27, 2020, former President Trump signed into law the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act")
which included certain changes in tax law intended to stimulate the U.S. economy in light of the COVID-19 coronavirus outbreak, including temporary
beneficial changes to the treatment of net operating losses, interest deductibility limitations and payroll tax matters. It cannot be predicted whether, when,
in what form or with what effective dates tax laws, regulations and rulings may be enacted, promulgated or issued, which could result in an increase in our
or our shareholders’ tax liability or require changes in the manner in which we operate in order to minimize or mitigate any adverse effects of changes in
tax law.

Risks Related to our Indenture for our Convertible Notes, Charter and Bylaws

Provisions in the Indenture for our Convertible Notes, corporate charter documents and under Delaware law may prevent or frustrate attempts by our
stockholders to change our management or hinder efforts to acquire a controlling interest in us.

Provisions in our corporate charter and our bylaws may discourage, delay or prevent a merger, acquisition or other change in control of us that stockholders
may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions could also limit the price
that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition,
because our board of directors is responsible for appointing the members of our management team, these provisions may frustrate or prevent any attempts
by  our  stockholders  to  replace  or  remove  our  current  management  by  making  it  more  difficult  for  stockholders  to  replace  members  of  our  board  of
directors. Among other things, these provisions:

<

<

<

<

<

<

<

establish  a  classified  board  of  directors  such  that  all  members  of  the  board  are  not  elected  at  one  time;  allow  the  authorized  number  of  our
directors to be changed only by resolution of our board of directors; and limit the manner in which stockholders can remove directors from the
board;
establish advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on at
stockholder meetings;
require  that  stockholder  actions  must  be  effected  at  a  duly  called  stockholder  meeting  and  prohibit  actions  by  our  stockholders  by  written
consent;
limit who may call a special meeting of stockholders;
authorize  our  board  of  directors  to  issue  preferred  stock  without  stockholder  approval,  which  could  be  used  to  institute  a  “poison  pill”  that
would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by our
board of directors;
require  the  approval  of  the  holders  of  at  least  two-thirds  of  the  votes  that  all  our  stockholders  would  be  entitled  to  cast  to  amend  or  repeal
certain provisions of our charter or bylaws; and
provide  that  the  Court  of  Chancery  of  the  State  of  Delaware  will  be  the  exclusive  forum  for  any  state  law  derivative  action  or  proceeding
brought  on  our  behalf,  any  action  asserting  a  breach  of  fiduciary  duty  by  one  or  more  of  our  directors,  officers  or  employees,  any  action
asserting a claim against us pursuant to the Delaware General Corporation Law, or any action asserting a claim against us that is governed by
the internal affairs doctrine, and that the United States District Court for the District of Illinois will be the exclusive forum for claims arising
under the Securities Act of 1933, as amended (the "Securities Act").

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the General Corporation Law of the State of
Delaware, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three
years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is
approved in a prescribed manner. This could discourage, delay or prevent someone from acquiring us or merging with us, whether or not it is desired by, or
beneficial  to,  our  stockholders.  This  could  also  have  the  effect  of  discouraging  others  from  making  tender  offers  for  our  common  stock,  including
transactions that may be in our stockholders’ best interests. These provisions may also prevent changes in our management or limit the price that investors
are willing to pay for our stock.

In addition, certain provisions in the Indenture governing our Convertible Notes could make a third-party attempt to acquire us more difficult or expensive.
For  example,  if  a  takeover  constitutes  a  fundamental  change,  then  noteholders  will  have  the  right  to  require  us  to  repurchase  their  notes  for  cash.  In
addition, if a takeover constitutes a make-whole fundamental change, then we may be required to temporarily increase the conversion rate. In either case,
and in other cases, our obligations under the notes and the indenture could increase the cost of acquiring us or otherwise discourage a third party from
acquiring us or removing incumbent management, including in a transaction that noteholders or holders of our common stock may view as favorable.

Our  bylaws  designate  certain  courts  as  the  sole  and  exclusive  forums  for  certain  types  of  actions  and  proceedings  that  may  be  initiated  by  our
stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees
and may discourage such lawsuits with respect to such claims.

Our amended and restated bylaws provide that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will be
the sole and exclusive forum for any state law claim for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of
breach of or based on a fiduciary duty owed by any of our directors, officers and employees to us or our stockholders, (iii) any action asserting a claim
arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws, or (iv) any action asserting a
claim that is governed by the internal affairs doctrine, in each case subject to the Court of Chancery having personal jurisdiction over the indispensable
parties named as defendants therein (the “Delaware Forum Provision”). The Delaware Forum Provision will not apply to any causes of action arising

85

under  the  Securities  Act  or  the  Securities  Exchange  Act  of  1934.  In  addition,  our  amended  and  restated  bylaws  further  provide  that  the  United  States
District  Court  for  the  Northern  District  of  Illinois  will  be  the  exclusive  forum  for  resolving  any  complaint  asserting  a  cause  of  action  arising  under  the
Securities Act (the “Federal Forum Provision”). We have chosen the United States District Court for the Northern District of Illinois as the exclusive forum
for Securities Act causes of action because our principal executive offices are located in Chicago, Illinois. Our amended and restated bylaws also provide
that 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
Delaware Forum Provision and the Federal Forum Provision.

On December 19, 2018, in Sciabacucchi v. Salzberg, C.A. No. 2017-0931-JTL (Del. Ch.), the Delaware Court of Chancery issued a decision declaring that
federal  forum  selection  provisions  purporting  to  require  claims  under  the  Securities  Act  be  brought  in  federal  court  are  ineffective  and  invalid  under
Delaware law. However, that decision was appealed to the Delaware Supreme Court, and on March 18, 2020, the Delaware Supreme Court reversed the
Court  of  Chancery  and  ruled  that  such  federal  forum  selection  provisions  are  “facially  valid”  under  Delaware  Law.  In  light  of  the  Delaware  Supreme
Court’s ruling, we intend to enforce our Federal Forum Provision designating the Northern District of Illinois as the exclusive forum for Securities Act
claims.

We  also  recognize  that  the  Delaware  Forum  Provision  and  the  Federal  Forum  Provision  in  our  bylaws  may  impose  additional  litigation  costs  on
stockholders in pursuing any such claims, particularly if the stockholders do not reside in or near the State of Delaware or the Northern District of Illinois.
Additionally, the Delaware Forum Provision and/or the Federal Forum Provision may limit a stockholder’s ability to bring a claim in a judicial forum that it
finds favorable for disputes with us or our directors, officers or employees, which may discourage such lawsuits against us and our directors, officers and
employees even though an action, if successful, might benefit our stockholders. The Federal Forum Provision may also impose additional litigation costs
on stockholders who assert the provision is not enforceable. The Court of Chancery of the State of Delaware or the United States District Court for the
Northern District of Illinois may also reach different judgments or results than would other courts, including courts where a stockholder considering an
action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders.

General Risk Factors

If we experience significant disruptions in our information technology systems, our business may be adversely affected.

We depend on our information technology systems for the efficient functioning of our business, including accounting, data storage, compliance, purchasing
and inventory management. Our current systems are not fully redundant. While we will attempt to mitigate interruptions, we may experience difficulties in
implementing some upgrades which would impact our business operations, or experience difficulties in operating our business during the upgrade, either of
which could disrupt our operations, including our ability to timely ship and track product orders, project inventory requirements, manage our supply chain
and otherwise adequately service our customers. In the event we experience significant disruptions of our information technology systems, we may not be
able to repair our systems in an efficient and timely manner. Accordingly, such events may disrupt or reduce the efficiency of our entire operation and have
a material adverse effect on our results of operations and cash flows.

We are increasingly dependent on sophisticated information technology for our infrastructure. Our information systems require an ongoing commitment of
significant resources to maintain, protect and enhance existing systems. Despite our implementation of security measures, our information systems, like
those  of  other  companies,  are  vulnerable  to  damages  from  computer  viruses,  natural  disasters,  unauthorized  access,  cyber  attack  and  other  similar
disruptions. Any system failure, accident or security breach could result in disruptions to our operations. For example, third parties may attempt to hack
into systems and may obtain our proprietary information, which could cause significant damage to our reputation, lead to claims against the Company and
ultimately harm our business.

As  a  result  of  being  a  public  company,  we  will  continue  to  incur  significant  additional  costs  which  may  adversely  affect  our  operating  results  and
financial condition.

We expect to continue to incur costs associated with corporate governance requirements, including requirements under the Sarbanes-Oxley Act of 2002, as
amended, or the Sarbanes-Oxley Act, as well as rules implemented by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the
Dodd-Frank  Act,  the  SEC  and  The  Nasdaq  Global  Select  Market.  These  rules  and  regulations  have  increased  our  accounting,  legal  and  financial
compliance  costs  and  make  some  activities  more  time  consuming  and  costly.  In  addition,  we  will  continue  to  incur  costs  associated  with  our  public
company reporting requirements, and we expect those costs may increase in the future. For example, we have devoted and expect to continue to devote
significant resources to complete the assessment and documentation of our internal controls over financial reporting under Section 404 of the Sarbanes-
Oxley Act, including assessment of the design and effectiveness of our internal controls related to our information systems.

86

During the course of our ongoing review and testing of our internal controls, we may identify deficiencies and may incur significant costs to remediate such
deficiencies, including material weaknesses, if any, that we identify through these efforts. We cannot predict or estimate the amount of additional costs we
may incur or the timing of such costs.

New laws and regulations, as well as changes to existing laws and regulations affecting public companies, including the provisions of the Sarbanes-Oxley
Act, the Dodd-Frank Act and rules adopted by the SEC and The Nasdaq Global Select Market, would likely result in increased costs to us as we respond to
their requirements, which may adversely affect our operating results and financial condition.

Securities analysts may publish inaccurate or unfavorable research or reports about our business or may publish no information at all, which could
cause our stock price or trading volume to decline.

The trading market for our common stock is influenced by the research and reports that industry or financial analysts publish about us and our business. We
do not control these analysts. As a newly public company, the analysts who publish information about our common stock will have had relatively little
experience with our company, which could affect their ability to accurately forecast our results and could make it more likely that we fail to meet their
estimates. If any of the analysts who cover us provide inaccurate or unfavorable research or issue an adverse opinion regarding our stock price, our stock
price could decline. If one or more of these analysts cease coverage of our company or fail to publish reports covering us regularly, we could lose visibility
in the market, which in turn could cause our stock price or trading volume to decline.

We enter into various contracts in the normal course of our business in which we indemnify the other party to the contract. In the event we have to
perform under these indemnification provisions, it could have a material adverse effect on our business, financial condition and results of operations.

In the normal course of business, we periodically have entered, and in the future may enter, into academic, commercial, service, collaboration, licensing,
feasibility,  consulting  and  other  agreements  that  contain  indemnification  provisions.  We  have  in  the  past  and  may  in  the  future  agree  to  indemnify  the
counterparties  from  losses  arising  from  claims  relating  to  the  products,  processes  or  services  made,  used,  sold  or  performed.  We  may  also  agree  to
indemnify our vendors from any third-party product liability claims that could result from the production, use or consumption of the product, as well as for
alleged infringements of any patent or other intellectual property right by a third party.

Should our obligation under an indemnification provision exceed applicable insurance coverage or if we were denied insurance coverage, our business,
financial condition and results of operations could be adversely affected. Similarly, if we are relying on a collaborator to indemnify us and the collaborator
is denied insurance coverage or the indemnification obligation exceeds the applicable insurance coverage and the collaborator does not have other assets
available to indemnify us, our business, financial condition and results of operations could be adversely affected.

We could be subject to securities class action litigation.

In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is
especially relevant for us because biotechnology and pharmaceutical companies have experienced significant stock price volatility in recent years. If we
face this type of litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

We are an “emerging growth company” and a "smaller reporting company," and the reduced disclosure requirements applicable to “emerging growth
companies” and "smaller reporting companies" may make our common stock less attractive to investors.

We  are  an  “emerging  growth  company,”  as  defined  in  the  Jumpstart  Our  Business  Startups  Act  of  2012  ("JOBS  Act")  and  we  have  elected  to  take
advantage of certain exemptions and relief from various reporting requirements that are applicable to other public companies that are not “emerging growth
companies.” In particular, while we are an “emerging growth company,” (i) we will not be required to comply with the auditor attestation requirements of
Section 404(b) of the Sarbanes-Oxley Act, (ii) we will be exempt from any rules that may be adopted by the Public Company Accounting Oversight Board
requiring  mandatory  audit  firm  rotations  or  a  supplement  to  the  auditor’s  report  on  financial  statements,  (iii)  we  will  be  subject  to  reduced  disclosure
obligations regarding executive compensation in our periodic reports and proxy statements and (iv) we will not be required to hold nonbinding advisory
votes on executive compensation or stockholder approval of any golden parachute payments not previously approved.

As  a  result,  our  public  filings  may  not  be  comparable  to  companies  that  are  not  “emerging  growth  companies”.  We  may  remain  an  “emerging  growth
company”  until  the  fiscal  year-end  following  the  fifth  anniversary  of  the  completion  of  our  IPO,  though  we  may  cease  to  be  an  “emerging  growth
company” earlier under certain circumstances, including (i) if the market value of our common stock that is held by non-affiliates exceeds $700 million as
of any June 30, in which case we would cease to be an “emerging growth

87

company” as of the following January 1, (ii) the date on which we have issued more than $1.0 billion in non-convertible debt during the previous three
years, or (iii) if our gross revenue exceeds $1.07 billion in any fiscal year.

In  addition,  the  JOBS  Act  provides  that  an  emerging  growth  company  can  take  advantage  of  an  extended  transition  period  for  complying  with  new  or
revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would
otherwise apply to private companies. In addition, we qualify as a “smaller reporting company,” which allows us to take advantage of many of the same
exemptions from disclosure requirements, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-
Oxley  Act  and  reduced  disclosure  obligations  regarding  executive  compensation  in  our  periodic  reports  and  proxy  statements.  Even  after  we  no  longer
qualify as an “emerging growth company,” we may still qualify as a “smaller reporting company” if the market value of our common stock that is held by
nonaffiliates is below $250 million (or $700 million if our annual revenue is less than $100 million) as of June 30 in any given year, which would allow us
to continue to take advantage of these exemptions.

Investors may find our common stock less attractive if we rely on these exemptions and relief granted by the JOBS Act. If some investors find our common
stock  less  attractive  as  a  result,  there  may  be  a  less  active  trading  market  for  our  common  stock  and  our  stock  price  may  decline  and/or  become  more
volatile.

ITEM 1B. UNRESOLVED STAFF COMMENTS

The Company has no unresolved written comments regarding its periodic or current reports from the staff of the U.S. Securities and Exchange Commission
("SEC").

ITEM 2. PROPERTIES

Our principal office is located in Chicago, Illinois and occupies approximately 41,000 square feet of leased space. The lease term expires on June 30, 2031.
In  the  fourth  quarter  of  2020,  we  relocated  our  research  and  development  laboratory  site  from  San  Diego,  California  to  Chicago.  Our  research  and
development laboratory site in Chicago occupies approximately 10,887 square feet of leased space under a 156-month lease through December 2033. We
currently believe that our offices are suitable and adequate to meet our needs.

ITEM 3. LEGAL PROCEEDINGS

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

ITEM 4. MINE SAFETY DISCLOSURES

Not applicable.

PART II

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

Market Information

Our common stock has been publicly traded on The Nasdaq Global Select Market under the symbol “XERS” since June 21, 2018. Prior to that time, there

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

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and
related notes appearing elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve significant risks
and  uncertainties.  Our  actual  results  could  differ  materially  from  those  discussed  in  these  forward-looking  statements.  Factors  that  could  cause  or
contribute to such differences include, but are not limited to, those set forth in Part I, Item 1A. Risk Factors, of this Annual Report on Form 10-K.

Overview

Unless  otherwise  indicated,  references  to  "Xeris,"  the  "Company,"  "we,"  "our"  and  "us"  in  this  Annual  Report  on  Form  10-K  refer  to  Xeris
Pharmaceuticals, Inc.

We are a specialty pharmaceutical company delivering innovative solutions to simplify the experience of administering important therapies that people rely
on  every  day  around  the  world.  With  novel  technology  platforms,  XeriSol™  and  XeriJect™,  that  enable  ready-to-use,  room-temperature  stable
formulations of injectable and infusible therapies, we are advancing a portfolio of solutions in various therapeutic categories. Our first product, Gvoke®,
delivers ready-to-use glucagon via a pre-filled syringe ("Gvoke PFS") or auto-injector ("Gvoke HypoPen®") for the treatment of severe hypoglycemia, a
potentially life-threatening condition, in people with diabetes. Gvoke was approved in September 2019 by the U.S. Food & Drug Administration ("FDA")
for the treatment of severe hypoglycemia in pediatric and adult patients with diabetes ages two years and older. We began the field launch of Gvoke PFS
and Gvoke HypoPen in January 2020 and July 2020, respectively, and each is available in two doses: a 0.5 mg/0.1 mL dose for pediatric patients and a 1
mg/0.2 mL dose for adolescent and adult patients. On February 11, 2021 the European Commission ("EC") granted a marketing authorization for Ogluo®
(glucagon) for the treatment of severe hypoglycemia in adults, adolescents, and children aged two years and over with diabetes mellitus. We currently plan
to  commercially  launch  Ogluo  in  select  European  countries  beginning  in  the  fourth  quarter  of  2021.  We  are  also  continuing  to  evaluate  additional
applications  of  our  ready-to-use  glucagon  formulation  to  address  needs  in  hypoglycemia  and  related  conditions.  In  addition,  we  are  applying  our
technology platforms to other commercially available drugs to enable more convenient and patient-friendly subcutaneous ("SC") and intramuscular ("IM")
routes of administration, including the development of products to address unmet needs in both diabetes and epilepsy. We own the rights to our proprietary
formulation  technology  platforms,  Gvoke,  and  our  product  candidates  domestically  and  internationally,  with  117  patents  issued  globally,  including  a
composition of matter patent covering our ready-to-use glucagon formulation that expires in 2036.

Our formulation technologies have broad applicability across many therapeutic areas. There is increasing interest in our technology platforms by other drug
development companies that seek higher drug concentrations and drug combinations in subcutaneous forms. In addition to use of these technologies for
development  of  our  own  product  candidates,  we  are  currently  conducting  three  technology  platform  collaboration  projects  with  top  tier  pharmaceutical
companies. Additional projects are under discussion with both large pharmaceutical and specialized biotech companies.

Our key priority is continuing the successful commercialization of our first product, Gvoke, for the treatment of severe hypoglycemia, while increasing the
adoption and penetration of emergency glucagon therapy, by offering a glucagon product that better meets the needs of patients and caregivers.

We have built a commercial organization, including hiring individuals in commercial operations and sales and marketing, to support the commercialization
of Gvoke in the United States. Outside the United States we may commercialize Ogluo with internal resources and/or pursue a commercialization partner in
order  to  broaden  the  availability  of  Ogluo  to  more  European  countries.  We  currently  contract  with  third  parties  for  the  manufacture,  assembly,  testing,
packaging, storage and distribution of our products.

Since our inception in 2005, we have devoted substantially all of our resources to research and development initiatives, undertaking preclinical studies of
our  product  candidates,  conducting  clinical  trials  of  our  most  advanced  product  candidates,  organizing  and  staffing  our  company,  raising  capital  and
commercializing our first product, Gvoke.

We have funded our operations to date primarily with proceeds from the sale of our preferred and common stock and debt financing. We have received
gross  proceeds  of  $226.0  million  from  public  equity  offerings  of  our  common  stock  (including  our  June  2018  initial  public  offering  ("IPO")  and  our
February 2019, February 2020 and June 2020 offerings), $104.9 million from sales of our preferred stock, $86.3 million from our June 2020 Convertible
Notes offering and $60.0 million from the Amended and Restated Loan and Security Agreement (as amended, the "Amended Loan Agreement"), of which
$20  million  was  repaid  in  June  2020.  In  August  2019,  we  filed  a  shelf  registration  statement  on  Form  S-3  with  the  U.S.  Securities  and  Exchange
Commission ("SEC"), which covers the offering, issuance and sale by us of up to an aggregate of $250.0 million of our common stock, preferred stock,
debt securities, warrants and/or units, which we refer to as the "Shelf". We simultaneously entered into a Sales Agreement with Jefferies LLC, as sales
agent, to provide for the offering, issuance and sale by us of up to $50.0 million of our common stock from time to time in at-the-market offerings under the
Shelf.

90

In February 2020, we completed an equity offering and sold 10,299,769 shares of common stock, including 1,299,769 shares pursuant to the underwriters’
option  to  purchase  additional  shares  of  common  stock.  Net  proceeds  from  the  offering  were  $39.9  million.  In  June  2020,  we  completed  a  public  notes
offering and sold $86.3 million aggregate principal amount of 5.00% Convertible Senior Notes, including $11.3 million pursuant to the underwriters' option
to purchase additional notes which was exercised in full in July 2020. Concurrent with the public notes offering, in June 2020 we completed an equity
offering  and  sold  8,510,000  shares  of  common  stock,  including  1,110,000  shares  pursuant  to  the  underwriters’  option  to  purchase  additional  shares  of
common stock which also was exercised in full in July 2020. Gross proceeds from the equity offering were $23.1 million. Net proceeds from both June
2020 offerings were $102.8 million. There currently remains $96.1 million available for future offerings under the Shelf. During the second half of 2020,
$39.1 million in principal amount of Convertible Notes were converted into 13,171,791 shares of the Company’s common stock. As of December 31, 2020,
the outstanding balance of Convertible Notes was $47.2 million. In October 2020, we entered into a fourth amendment to the Amended Loan Agreement,
which provided for an additional $3.5 million term loan which was drawn in November 2020. As of December 31, 2020, the outstanding balance under the
Amended Loan Agreement was $43.5 million.

For the years ended December 31, 2020 and 2019, we reported net losses of $91.1 million and $125.6 million, respectively. We have not been profitable
since inception, and, as of December 31, 2020, our accumulated deficit was $337.4 million. In the near term, we expect to continue to incur significant
expenses, operating losses and net losses as we:

<    continue our marketing and selling efforts related to commercialization of Gvoke;
<    continue our research and development efforts;
<    seek regulatory approval for new product candidates and product enhancements; and
<    continue to operate as a public company.

We began our field launch of Gvoke in January 2020 and have not yet generated significant product revenue from sales of Gvoke. We may continue to seek
public equity and debt financing to meet our capital requirements. There can be no assurance that such funding may be available to us on acceptable terms,
or at all, or that we will be able to commercialize our product candidates, if approved. In addition, we may not be profitable even if we commercialize any
of our product candidates.

Impact of COVID-19

The  current  novel  coronavirus  (“COVID-19”)  pandemic  has  presented  a  substantial  public  health  and  economic  challenge  around  the  world  and  has
impacted our business operations, employees, patients and communities as well as the global economy and financial markets. The COVID-19 pandemic
continues to evolve and to date has led to the implementation of various responses, including government-imposed quarantines, stay-at-home orders, travel
restrictions, mandated business closures and other public health safety measures.

To date, we and our suppliers and third-party manufacturing partners have been able to continue to supply our products to our patients and currently do not
anticipate any interruptions in supply. Our third-party contract manufacturing partners continue to operate at or near normal levels, with enhanced safety
measures intended to prevent the spread of the virus. While we currently do not anticipate any interruptions in our manufacturing process, it is possible that
the COVID-19 pandemic and response efforts may have an impact in the future on our third-party suppliers and contract manufacturing partners' ability to
supply and/or manufacture our products.

We believe that customer demand for Gvoke has been adversely impacted by the COVID-19 pandemic due to the disruption the pandemic has caused in
patients' normal access to healthcare as well as our sales and marketing personnel's access to customers. Initially, we suspended in-person interactions by
our sales and marketing personnel in healthcare settings. We are engaging with these customers remotely, via webinar programs and virtual meetings, as we
seek to continue to support healthcare professionals and patient care. As parts of the country reopened, some of our sales and marketing personnel began to
reengage  with  a  limited  number  of  in-person  interactions.  However,  with  the  resurgence  of  COVID-19  in  many  areas,  our  ability  to  connect  with  our
customers in person became much more limited and we are currently back to almost exclusively remote interactions. Remote interactions generally are not
as effective as in-person interactions. In addition, several conferences and other programs at which we intended to market Gvoke have been postponed,
canceled and/or transitioned to virtual meetings. We also have revised our patient copay assistance program to offer a copay card with a buy-down to $0 for
commercially eligible patients in response to the COVID-19 pandemic.

As  the  COVID-19  pandemic  unfolded,  we  moved  quickly  to  transition  our  employees  to  a  remote  work-from-home  environment  excluding  essential
services, such as personnel in our laboratory. For those employees, we have implemented safety measures designed to comply with applicable federal, state
and local guidelines in response to the COVID-19 pandemic. We may be required to take additional actions that may impact our operations as required by
applicable laws or regulations or which we determine to be in the best interests of our employees.

We have incurred operating losses since inception, and we have an accumulated deficit of $337.4 million at December 31, 2020. Although we believe that
our  cash,  cash  equivalents,  investments,  and  expected  revenue  from  sales  of  Gvoke  will  enable  us  to  fund  our  operating  and  capital  expenditure
requirements for at least the next 12 months, we cannot predict the impact of the COVID-19

91

pandemic  on  our  future  results  of  operations  and  financial  condition  due  to  a  variety  of  factors,  including  the  health  of  our  employees,  the  ability  of
suppliers to continue to operate and deliver, the ability of Xeris and our customers to maintain operations, continued access to transportation resources, the
changing needs and priorities of customers, any further government and/or public actions taken in response to the pandemic and ultimately the length of the
pandemic.  As  further  detailed  in  "Liquidity  and  Capital  Resources"  below,  we  have  relied  on  equity  and  debt  financing  for  our  funding  to  date  and
completed concurrent convertible debt and equity offerings in June/July 2020 under which we raised gross proceeds of $109.4 million. Given the impact of
COVID-19 on the U.S. and global financial markets, we may be unable to access further equity or debt financing if and when needed. In addition, in order
to conserve cash, we implemented measures to reduce spending, we delayed or suspended projects, and we adopted a deferred compensation plan under
which a select group of management and our non-employee directors may defer receiving all or a portion of their cash compensation. Our chief executive
officer,  Paul  Edick,  deferred  approximately  85%  of  his  cash  compensation  for  the  majority  of  2020  to  reduce  cash  burn,  and  other  members  of  our
executive team and board of directors also deferred a significant portion of their compensation. In addition, in April 2020, we entered into the U.S. Small
Business Administration (the “SBA”) Paycheck Protection Program (the “PPP”) Note (the “Note”) with Silicon Valley Bank (the “Lender”) for a loan in
the amount of $5.1 million (the “PPP Loan”), enabled by the Coronavirus Aid, Relief and Economic Security Act of 2020 (the “CARES Act”) to retain
employees, maintain payroll and make lease and utility payments in accordance with the relevant terms and conditions of the CARES Act. In May 2020,
we repaid $0.9 million of the PPP Loan, and in June 2020 we repaid the remaining $4.2 million outstanding under the PPP Loan out of proceeds from our
concurrent convertible debt and equity offerings.

We are closely monitoring the impact of the COVID-19 pandemic on all aspects of our business, including the impact on our operations and the operations
of our customers, suppliers, vendors and business partners. We may take further precautionary and preemptive actions as may be required by federal, state
or local authorities. In addition, we have taken and continue to take steps to try and minimize the current environment’s impact on our business, including
devising contingency plans and backup resources.

We  do  not  yet  know  the  full  extent  of  potential  delays  or  impacts  on  our  business,  our  clinical  trials,  our  research  programs,  healthcare  systems  or  the
global economy, and we cannot presently predict the scope and severity of any potential business shutdowns or disruptions. The full extent to which the
COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including sales, expenses, reserves and
allowances,  manufacturing,  clinical  trials,  research  and  development  costs  and  employee-related  amounts,  will  depend  on  future  developments  that  are
highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat it, as well as the
economic  impact  on  local,  regional,  national  and  international  markets.  If  we,  or  any  of  the  third  parties  with  whom  we  engage,  were  to  experience
shutdowns or other business disruptions, our ability to conduct our business in the manner and on the timelines presently planned could be materially or
negatively affected, which could have a material adverse impact on our business, results of operations and financial condition.

Components of our Results of Operations

Net Sales

Net  sales  represent  gross  product  sales  less  estimated  allowances  for  patient  copay  assistance  programs,  prompt  payment  discounts,  payor  rebates,
chargebacks, service fees, and product returns, all of which are recorded at the time of sale to the pharmaceutical wholesaler or other customer. We apply
significant  judgments  and  estimates  in  determining  some  of  these  allowances.  If  actual  results  differ  from  our  estimates,  we  will  be  required  to  make
adjustments to these allowances in the future. See "Critical Accounting Policies and Use of Estimates and Assumptions" for further information regarding
the significant judgments and estimates involved in the determination of net sales.

Cost of Goods Sold

Cost of goods sold includes primarily product costs, which include all costs directly related to the purchase of raw materials, charges from our contract
manufacturing organizations, and manufacturing overhead costs, as well as shipping and distribution charges. Cost of goods sold also includes losses from
excess, slow-moving or obsolete inventory and inventory purchase commitments, if any. Manufacturing costs incurred for Gvoke PFS and Gvoke HypoPen
prior to approval and initial commercialization were expensed as research and development expenses.

Research and Development Expenses

Research  and  development  expenses  consist  of  expenses  incurred  in  connection  with  the  discovery  and  development  of  our  product  candidates.  We
recognize  research  and  development  expenses  as  incurred.  Research  and  development  expenses  that  are  paid  in  advance  of  performance  are  capitalized
until services are provided or goods are delivered. Research and development expenses include:

<    the cost of acquiring and manufacturing preclinical and clinical trial materials and manufacturing costs related to commercial production and scale-up

until a product is approved and initially available for commercial sale;

92

<    expenses incurred under agreements with contract research organizations ("CROs") as well as investigative sites and consultants that conduct our

preclinical studies and clinical trials;

<    personnel-related expenses, which include salaries, benefits and stock-based compensation;
<    laboratory materials and supplies used to support our research activities;
<    outsourced product development services;
<    expenses relating to regulatory activities, including filing fees paid to regulatory agencies; and
<    allocated expenses for facility-related costs.

Research and development activities are central to our business model. We expect to continue to incur significant research and development expenses as we
continue to plan and conduct clinical trials, prepare regulatory filings for our product candidates, and utilize internal resources to support these efforts. Our
research and development costs have declined as compared to previous levels as a result of directing significant funding to our commercial activities, with
the approval and launch of our first product, Gvoke, and as we have concluded ongoing clinical programs and not initiated any new studies as we finalize
our discussions with the FDA on go-forward development requirements. We expect to continue to incur research and development expenses as we continue
to advance our pipeline candidates.

Our  research  and  development  expenses  may  vary  significantly  over  time  due  to  uncertainties  relating  to  the  timing  and  results  of  our  clinical  trials,
feedback received from interactions with the FDA and the timing of regulatory approvals.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist principally of compensation and related personnel costs, marketing and selling expenses, professional
fees and facility costs not otherwise included in cost of goods sold or research and development expenses. Our selling and marketing costs have increased
significantly as we continue our marketing and selling efforts for Gvoke in the United States. We expect to continue to incur significant marketing and
selling expenses in the near term related to the commercialization of Gvoke both in and outside the United States.

As a public reporting company, we have incurred greater expenses, including increased payroll, legal and compliance, accounting, insurance and investor
relations costs. We expect some of these costs to continue to increase in conjunction with our anticipated growth as a public reporting company.

Other Income (Expense)

Other income (expense) consists primarily of interest expense related to our convertible debt and loan agreements, interest income earned on deposits and
investments, and the change in fair value of our warrants.

Income Tax

We  have  incurred  operating  losses  since  inception  and  therefore  do  not  have  any  taxable  income.  As  of  December  31,  2020,  we  had  $284.8  million  in
federal net operating loss carryforwards, $220.6 million of various state net operating loss carryforwards, $8.0 million in federal research and orphan drug
credits that begin to expire in 2025, and $1.7 million of state research and development credits that will begin to expire in 2022.

We commercially launched Gvoke PFS and Gvoke HypoPen for the treatment of severe hypoglycemia in people with diabetes in November 2019 and July
2020, respectively. Total net sales of Gvoke were $20.2 million and $1.6 million for the years ended December 31, 2020 and 2019, respectively. Net sales
represent  gross  product  sales  less  estimated  allowances  for  patient  copay  assistance  programs,  prompt  payment  and  other  discounts,  payor  rebates,
chargebacks, service fees, and product returns, all of which are recorded at the time of sale to the pharmaceutical wholesaler or other customer. We apply
significant  judgments  and  estimates  in  determining  some  of  these  allowances.  If  actual  results  differ  from  our  estimates,  we  will  be  required  to  make
adjustments to these allowances in the future.

Grant and Other Income

Grant and other income decreased by $0.8 million for the year ended December 31, 2020 when compared to the year ended December 31, 2019, primarily
due to the completion of grant programs in the first quarter of 2020.

Cost of Goods Sold

Cost  of  goods  sold  was  $9.3  million  for  the  year  ended  December  31,  2020,  which  included  $2.3  million  related  to  excess  and  obsolete  inventory  and
under-absorbed overhead costs of $1.5 million. Cost of goods sold was $1.6 million for the year ended December 31, 2019, which included under-absorbed
overhead  costs  of  $0.6  million.  Manufacturing  costs  for  Gvoke  incurred  prior  to  approval  and  initial  commercialization  were  expensed  as  incurred  as
research and development expenses.

Research and Development Expenses

Research and development expenses decreased $39.5 million for the year ended December 31, 2020 when compared to the year ended December 31, 2019.
The  decrease  was  primarily  driven  by  expenses  incurred  in  the  prior  year  for  the  manufacturing  of  Gvoke  prior  to  commercialization  of  $14.0  million,
decreased expenses associated with our clinical trials of $13.7 million, a reduction of manufacturing batches and supplies needed for preclinical and clinical
trials of $10.3 million, and an increase in the allocation of

94

 
certain personnel and facilities costs to costs of goods sold of $2.3 million, partially offset by restructuring expenses of $1.0 million in the current year
related to the relocation of our laboratory from San Diego to Chicago.
Selling, General and Administrative Expenses

Selling, general and administrative costs increased $10.7 million for the year ended December 31, 2020 when compared to the year ended December 31,
2019. The increase was primarily driven by an increase in compensation and related personnel costs of $12.0 million due to additional headcount to support
commercialization efforts of Gvoke and increased FDA registration fees of $1.0 million, partially offset by decreases in marketing and selling expenses of
$3.9 million due to the costs incurred in the prior year for the initial launch of Gvoke and decreased expenses related to conferences and programs due to
the COVID-19 pandemic.

Other Income (Expense)

For the year ended December 31, 2020, interest and other income increased $0.2 million in comparison to the year ended December 31, 2019, primarily as
a  result  of  a  legal  settlement  of  $1.5  million,  partially  offset  by  lower  interest  income  as  a  result  of  lower  average  balances  in  cash  equivalents  and
investments and lower interest rates.

For the year ended December 31, 2020, interest expense increased $3.5 million in comparison to the year ended December 31, 2019, primarily due to a loss
on conversion of convertible debt of $2.6 million in the current year, interest on the convertible notes issued in the June 2020 offering of $1.9 million, a
loss on extinguishment of debt of $0.7 million in the current year, and increased borrowing levels under the Amended Loan Agreement, partially offset by a
loss on extinguishment of debt of $2.3 million in the prior year.

Liquidity and Capital Resources

Our primary uses of cash are to fund costs related to the manufacturing, marketing and selling of Gvoke, the research and development of our product
candidates, general and administrative expenses and working capital requirements. Historically, we have funded our operations primarily through private
placements  of  convertible  preferred  stock,  public  equity  offerings  of  common  stock,  and  issuance  of  debt.  In  June  2018,  we  completed  our  IPO  of
6,555,000 shares of our common stock at a price of $15.00 per share for aggregate net proceeds of $88.9 million after deducting underwriting discounts and
commissions as well as other equity offering expenses. In February 2019, we completed an equity offering and sold an aggregate of 5,996,775 shares of
common  stock  at  a  price  of  $10.00  per  share.  Net  proceeds  from  this  equity  offering  were  $55.5  million  after  deducting  underwriting  discounts  and
commissions as well as other equity offering expenses. In September 2019, we entered into the Amended Loan Agreement that provides for term loans of
up to an aggregate of $85.0 million, of which $60.0 million was drawn in September 2019 and of which $20.0 million was repaid in June 2020. We become
eligible to draw the second tranche of $15.0 million and the third tranche of $10.0 million if certain revenue targets are achieved prior to March 31, 2021
and  June  30,  2021,  respectively.  We  currently  do  not  anticipate  that  such  milestones  will  be  achieved.  In  August  2019,  we  filed  a  shelf  registration
statement on Form S-3 with the SEC, which covers the offering, issuance and sale by us of up to an aggregate of $250.0 million of our common stock,
preferred stock, debt securities, warrants and/or units, which we refer to as the "Shelf". We simultaneously entered into a Sales Agreement with Jefferies
LLC, as sales agent, to provide for the offering, issuance and sale by us of up to $50.0 million of our common stock from time to time in "at-the-market"
offerings under the Shelf. As of December 31, 2020, we have sold an aggregate of 204,427 shares of common stock in at-the-market offerings under the
Shelf for gross proceeds of $1.8 million.

In February 2020, we completed an equity offering and sold 10,299,769 shares of common stock. Net proceeds from this equity offering were $39.8 million
after deducting underwriting discounts and commissions as well as other equity offering expenses. In June 2020, we completed a public notes offering and
sold $86.3 million aggregate principal amount of 5.00% Convertible Senior Notes, including $11.3 million pursuant to the underwriters' option to purchase
additional notes which was fully exercised in July 2020. Concurrently with the public notes offering, in June 2020, we completed an equity offering and
sold 8,510,000 shares of common stock, including 1,110,000 shares pursuant to the underwriters’ option to purchase additional shares of common stock
which also was fully exercised in July 2020. Net proceeds from both June 2020 offerings (including the net proceeds from the exercise of the underwriters'
over-allotment  options  in  July  2020)  were  $102.8  million  after  deducting  underwriting  discounts  and  commissions  as  well  as  other  offering  expenses.
During the second half of 2020, $39.1 million in principal amount of Convertible Notes were converted into 13,171,791 shares of the Company’s common
stock. As of December 31, 2020, the outstanding balance of Convertible Notes was $47.2 million. In October 2020, we entered into a fourth amendment to
the Amended Loan Agreement which, provided for an additional $3.5 million term loan which was drawn in November 2020. As of December 31, 2020,
the outstanding balance under the Amended Loan Agreement was $43.5 million.
Capital Resources and Funding Requirements

We  have  incurred  operating  losses  since  inception,  and  we  have  an  accumulated  deficit  of  $337.4  million  at  December  31,  2020.  Based  on  our  current
operating  plans  and  existing  working  capital  at  December  31,  2020,  we  believe  that  our  cash  resources  are  sufficient  to  sustain  operations  and  capital
expenditure requirements for at least the next 12 months. We expect to incur substantial

95

additional expenditures in the near term to support the marketing and selling of Gvoke and our ongoing research and development activities. We expect to
continue to incur net losses for at least the next 12 months. Our ability to fund our product development and clinical operations, including completion of
future clinical trials, as well as marketing and selling Gvoke and commercialization of our product candidates, if approved, will depend on the amount and
timing of cash received from future financings. Our future capital requirements will depend on many factors, including:

<    the costs of commercialization activities, including product marketing, sales and distribution;
<    our degree of success in commercializing Gvoke;
<    the costs, timing and outcomes of clinical trials and regulatory reviews associated with our product candidates;
<    the effect on our product development activities of actions taken by the FDA or other regulatory authorities;
<    the number and types of future products we develop and commercialize;
<    the emergence of competing technologies and products and other adverse market developments; and
<    the costs of preparing, filing and prosecuting patent applications and maintaining, enforcing and defending intellectual property-related claims.

As  we  continue  the  marketing  and  selling  of  our  first  product,  Gvoke,  we  may  not  generate  a  sufficient  amount  of  product  revenues  to  fund  our  cash
requirements. Accordingly, we may need to obtain additional financing in the future which may include public or private debt and/or equity financings.
There can be no assurance that such funding may be available to us on acceptable terms, or at all, or that we will be able to successfully market and sell
Gvoke and our product candidates, if approved. Market volatility resulting from the COVID-19 pandemic or other factors could also adversely impact our
ability to access capital as and when needed. The issuance of equity securities may result in dilution to stockholders. If we raise additional funds through
the issuance of additional debt, which may have rights, preferences and privileges senior to those of our common stockholders, the terms of the debt could
impose significant restrictions on our operations. The failure to raise funds as and when needed could have a negative impact on our financial condition and
ability  to  pursue  our  business  strategies.  If  additional  funding  is  not  secured  when  required,  we  may  need  to  delay  or  curtail  our  operations  until  such
funding is received, which would have a material adverse impact on our business prospects and results of operations.

The  decrease  in  cash  used  in  operating  activities  for  the  year  ended  December  31,  2020  was  primarily  driven  by  decreased  spending  in  research  and
development and net sales of Gvoke, partially offset by increased marketing, selling and manufacturing costs related to the commercialization of Gvoke.
For  a  discussion  regarding  the  net  sales  of  Gvoke  and  increases  in  spending,  refer  to  "Results  of  Operations"  included  in  this  Item  2,  "Management’s
Discussion and Analysis of Financial Condition and Results of Operations."

The  increase  in  net  cash  used  in  investing  activities  for  the  year  ended  December  31,  2020,  as  compared  to  the  year  ended  December  31,  2019,  was
primarily due to a decrease in sales and maturities of investments.

The  increase  in  cash  provided  by  financing  activities  for  the  year  ended  December  31,  2020,  as  compared  to  the  year  ended  December  31,  2019,  was
primarily due to the net proceeds of $81.2 million from the June 2020 convertible debt offering, the net proceeds of $39.9 million and $21.6 million from
the February 2020 and June 2020 equity offerings of our common stock, respectively, and proceeds of $3.5 million from the drawdown on the October
2020 amendment to the Amended Loan Agreement, partially offset by the paydown of principal on the Amended Loan Agreement in June 2020 of $20.0
million, as compared to the net proceeds of $57.2 million from the 2019 equity offerings of our common stock and net proceeds from the issuance of long-
term debt of $22.6 million in September 2019.

CRITICAL ACCOUNTING POLICIES AND USE OF ESTIMATES AND ASSUMPTIONS

Our  management’s  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  on  our  financial  statements  have  been  prepared  in
accordance with generally accepted accounting principles ("GAAP") in the United States. The preparation of these financial statements requires us to make
estimates that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements
as  well  as  the  reported  revenues  and  expenses  during  the  reporting  periods.  On  an  ongoing  basis,  we  evaluate  our  estimates  and  judgments,  including,
among others, those related to revenue recognition, clinical trial expenses and stock-based compensation. We base our estimates on historical experience
and  on  various  other  factors  we  believe  to  be  appropriate  under  the  circumstances.  Actual  results  may  differ  from  these  estimates  under  different
assumptions or conditions.

We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the
more significant areas involving management’s judgments and estimates. Our significant accounting policies are more fully described in Note 2, "Summary
of Significant Accounting Policies."

Revenue recognition

We apply the guidance in ASC 606 to all contracts with customers within the scope of the standard. We sell our product, Gvoke, which is available in two
presentations, a pre-filled syringe (Gvoke PFS) and an auto-injector (Gvoke HypoPen), primarily to pharmaceutical wholesalers. These wholesalers then
resell our products to their customers, such as retail pharmacies. In addition, we enter into arrangements with payors, group purchasing organizations, and
healthcare providers that provide for government-mandated or privately negotiated rebates, chargebacks and discounts related to our products. We currently
sell Gvoke in the U.S. only.

Revenue is recognized when our customer (e.g., a wholesaler) obtains control of promised goods or services, which is when our obligations under the terms
of our contract with the customer are satisfied, based on the consideration we expect to receive in exchange for those goods or services. The estimated net
sales  price  is  generally  based  on  a  list  or  fixed  price  less  estimates  of  variable  consideration  (e.g.,  patient  copay  assistance,  prompt  payment  and  other
discounts, payor rebates, chargebacks, service fees and product returns). The estimates of variable consideration are subject to a constraint such that some
or  all  of  the  estimated  amount  of  variable  consideration  will  only  be  included  in  the  transaction  price  to  the  extent  that  it  is  probable  that  a  significant
reversal  of  revenue  will  not  occur  when  the  uncertainty  associated  with  the  variable  consideration  is  subsequently  resolved.  Estimating  variable
consideration and the related constraint requires the use of significant management judgment and other market data.

Net  sales  represent  gross  product  sales  less  estimated  allowances  for  patient  copay  assistance  programs,  prompt  payment  and  other  discounts,  payor
rebates,  chargebacks,  service  fees,  and  product  returns,  all  of  which  are  recorded  at  the  time  of  sale  to  the  pharmaceutical  wholesalers  or  other
customer. We apply significant judgments and estimates in determining some of these allowances. If actual results differ from our estimates, we will be
required to make adjustments to these allowances in the future.

    Patient Copay Assistance Program

We  offer  a  savings  program  to  commercially  insured  patients  under  which  the  cost  of  a  prescription  to  a  patient  is  discounted.  We  reimburse
pharmacies  for  this  discount  through  a  third-party  vendor.  We  record  an  accrual  to  reduce  gross  sales  for  the  estimated  copay  on  units  sold  to
wholesalers and other customers. The estimate is based on estimated percentages of products that will be prescribed to qualified patients, expected
patient utilization of the discount program, average assistance paid based on reporting from the third-party vendor as well as industry data and
levels of inventory in the distribution channel. Accrued copay fees are recorded as a reduction of revenue and included in accrued trade discounts
and rebates on the consolidated balance sheets.

    Prompt Payment Discounts

As an incentive for prompt payment, we offer a discount to most customers. We expect that all eligible customers will comply with the contractual
terms  to  earn  the  discount  and,  therefore,  we  accrue  the  discount  on  all  eligible  sales.  We  record  the  discount  as  an  allowance  against  trade
accounts receivable on the consolidated balance sheets and as a reduction of revenue.

    Commercial Rebates

We  contract  with  certain  private  payor  organizations,  primarily  insurance  companies  and  pharmacy  benefits  managers,  to  provide  rebates  with
respect  to  utilization  of  Gvoke  and  contracted  formulary  status.  We  accrue  estimated  rebates  based  on  contract  rates,  estimated  percentages  of
products that will be prescribed to qualified patients and estimated levels of inventory

97

in the distribution channel and record the rebate as a reduction of revenue. Accrued commercial rebates are included in accrued trade discounts
and rebates on the consolidated balance sheets.

    Government Rebates

We participate in certain federal and state government rebate programs such as the Medicaid Drug Rebate Program, TRICARE Retail Refunds
Program,  and  Medicare  Part  D  Program.  We  accrue  estimated  rebates  based  on  estimated  percentages  of  product  sold  to  qualified  patients,
estimated rebate percentages and estimated levels of inventory in the distribution channel that will be prescribed to qualified patients and record
the rebates as a reduction of revenue. Accrued government rebates are included in accrued trade discounts and rebates on the consolidated balance
sheets.

    Chargebacks

We have arrangements with certain commercial and government entities that allow them to buy our products directly from wholesalers at specific
prices.  These  entities  purchase  products  through  wholesalers  at  the  discounted  price,  and  the  wholesalers  charge  the  difference  between  their
acquisition cost and the discounted price back to us. We accrue estimated chargebacks based on estimated percentages of product sold to these
entities,  contract  prices,  and  estimated  levels  of  inventory  in  the  distribution  channel  and  record  the  chargebacks  as  a  reduction  of  revenue.
Accrued chargebacks are recorded as an allowance against trade receivables on the consolidated balance sheets.

    Service Fees

We record service fees paid to our wholesaler customers for distribution and inventory management services as a reduction to revenue. We accrue
estimated service fees based on contractually determined amounts. Accrued service fees are included in accrued trade discounts and rebates on the
consolidated balance sheets.

    Product Returns

Consistent  with  industry  practice,  our  customers  generally  have  the  right  to  return  product  during  the  period  beginning  six  months  prior  to  its
expiration date and up to one year after its expiration date. As our products are newly launched and we do not have history of product returns, we
estimate the provision for returns based on factors related to the launch of our products, third-party industry data for comparable products in the
market and estimated channel inventory data. As we distribute our products and establish historical sales over a longer period of time, we will be
able to place more reliance on historical purchasing and return patterns of our customers when evaluating our reserves for product returns. In a
reporting period, we may decide to constrain revenue for product returns based on information from various sources, including channel inventory
levels,  inventory  dating,  prescription  data,  the  expiration  dates  of  product  currently  being  shipped,  price  changes  of  competitive  products  and
introductions  of  generic  products.  While  we  believe  that  our  returns  reserve  is  sufficient  to  avoid  a  significant  reversal  of  revenue  in  future
periods, if we were to increase or decrease the rate by 1%, it would have a $0.2 million impact on revenue in the year ended December 31, 2020.
We record estimated sales returns in accrued returns reserve on the consolidated balance sheets and as a reduction of revenue.

Research and development accruals

Research and development expenses are expensed as incurred. Research and development expenses include salaries and related personnel costs, consulting
fees, fees paid for contract research and development services including those for preclinical and clinical trials, laboratory equipment and facilities costs,
and  other  external  costs.  In  addition,  manufacturing  costs  for  Gvoke  prior  to  approval  and  initial  commercialization  were  expensed  as  research  and
development expenses.

Nonrefundable  advance  payments  for  goods  or  services  to  be  received  in  the  future  for  use  in  research  and  development  activities  are  deferred  and
capitalized. The capitalized amounts are expensed as the related goods are used or the services are performed.

When preparing our financial statements, we are required to estimate our accrued clinical expenses. This process involves reviewing open contracts and
communicating  with  our  personnel  to  identify  services  that  have  been  performed  on  our  behalf  and  estimating  the  level  of  service  performed  and  the
associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost. Payments under some of the contracts we
have  with  parties  depend  on  factors,  such  as  successful  enrollment  of  certain  numbers  of  patients,  site  initiation  and  the  completion  of  clinical  trial
milestones. When accruing clinical expenses, we estimate the time period over which services will be performed and the level of effort to be expended in
each period. If possible, we obtain information regarding unbilled services directly from our service providers. However, we may be required to estimate
the cost of these services based only on information available to us. If we underestimate or overestimate the cost associated with a trial or service at a

98

given  point  in  time,  adjustments  to  research  and  development  expenses  may  be  necessary  in  future  periods.  Historically,  our  estimated  accrued  clinical
expenses have approximated actual expense incurred.

employee stock purchases under the employee stock purchase plan (in thousands):

We  account  for  our  stock-based  compensation  awards  in  accordance  with  Accounting  Standards  Codification  Topic  718,  Compensation-Stock
Compensation ("ASC 718"). ASC 718 requires all stock-based payments to employees, including grants of employee stock options, to be recognized in the
statements of operations based on their grant date fair values. We estimate the grant date fair value of each option award using the Black-Scholes option-
pricing  model.  We  recognize  stock-based  compensation  expense,  equal  to  the  grant  date  fair  value  of  stock  options,  on  a  straight-line  basis  over  the
requisite service period. We account for forfeitures as they are incurred.

Estimating the fair value of options requires the input of subjective assumptions, including the estimated fair value of our common stock, the expected life
of  the  option,  stock  price  volatility,  the  risk-free  interest  rate  and  expected  dividends.  The  assumptions  used  in  our  Black-Scholes  option-pricing  model
represent management’s best estimates and involve a number of variables, uncertainties and assumptions and the application of management’s judgment, as
they are inherently subjective. If any assumptions change, our stock-based compensation expense could be materially different in the future.

The assumptions used in our Black-Scholes option-pricing model are estimated as follows:

∎    Expected Term. We do not believe we are able to rely on our historical exercise and post-vesting termination activity to provide accurate data for
estimating  the  expected  term  for  use  in  determining  the  fair  value-based  measurement  of  our  options.  Therefore,  we  have  opted  to  use  the
“simplified method” for estimating the expected term of options, which is the average of the weighted-average vesting period and contractual
term of the option.

∎    Expected Volatility. As we have limited trading history for our common stock, the expected stock price volatility assumption is determined based
on the historical volatilities of a peer group of publicly traded companies for the period of the term prior to our IPO in June 2018 as well as the
historical volatility of our own common stock since we began trading subsequent to our IPO. In evaluating similarity, we consider factors such as
stage  of  development,  risk  profile,  enterprise  value  and  position  within  the  industry.  We  intend  to  continue  to  consistently  apply  this  process
using the same public companies until a sufficient amount of historical information regarding the volatility of our own common stock share price
becomes available.

∎    Risk-Free Interest Rate. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of the grant for the zero-coupon U.S.

Treasury note with a term similar to the expected term of the option.

∎    Expected Dividends. The expected dividend yield is 0% because we have not historically paid, and do not expect for the foreseeable future to

pay, a dividend on our common stock.

NEW ACCOUNTING STANDARDS

Refer  to  Note  2,  "Summary  of  Significant  Accounting  Policies,"  for  a  description  of  recent  accounting  pronouncements  applicable  to  our  financial
statements.

JOBS ACT ACCOUNTING ELECTION

In April 2012, the Jumpstart Our Business Startups Act of 2012 ("JOBS Act") was enacted. Section 107 of the JOBS Act provides that an emerging growth
company can take advantage of an extended transition period for complying with new or revised accounting standards. Thus, an emerging growth company
can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage
of such extended transition period.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks arising from transactions in the normal course of business, principally risk associated with interest rate and foreign
currency exchange rate fluctuations.

Interest Rate Risk

Cash and Cash Equivalents and Investments—We are exposed to the risk of interest rate fluctuations on the interest income earned on our cash and cash
equivalents  and  investments.  A  hypothetical  one-percentage  point  increase  or  decrease  in  interest  rates  applicable  to  our  cash  and  cash  equivalents  and
investments outstanding at December 31, 2020 would increase or decrease interest income by approximately $1.3 million on an annual basis.

Long-term Debt—Our interest rate risk relates primarily to U.S. dollar LIBOR-indexed borrowings. Based on our outstanding borrowings pursuant to the
Amended Loan Agreement at December 31, 2020, interest is incurred at a floating per annum rate in an amount equal to the sum of 6.25% plus the greater
of (a) 2.43% and (b) the thirty-day U.S. Dollar LIBOR rate. A one-percentage point increase in interest rates would have no impact on interest expense on
an annual basis as the thirty-day U.S. Dollar LIBOR rate at December 31, 2020 was 0.14%, which including a one-percent point increase would remain
below 2.43%. Interest on the Convertible Notes is assessed at a fixed rate of 5.0% annually and therefore does not subject us to interest rate risk.

Foreign Exchange Risk

We  contract  with  contract  research  organizations  outside  the  United  States.  We  may  be  subject  to  fluctuations  in  foreign  currency  exchange  rates  in
connection with certain of these agreements. Transactions denominated in currencies other than the functional currency are recorded based on exchange
rates at the time such transactions arise. As of December 31, 2020, we had immaterial liabilities denominated in the Australian Dollar. Net foreign currency
gains and losses did not have a material effect on our results of operations for the year ended December 31, 2020.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
Xeris Pharmaceuticals, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Xeris Pharmaceuticals, Inc. and subsidiaries (the Company) as of December 31, 2020
and  2019,  the  related  consolidated  statements  of  operations  and  comprehensive  loss,  stockholders’  equity,  and  cash  flows  for  each  of  the  years  in  the
two‑year  period  ended  December  31,  2020,  and  the  related  notes  (collectively,  the  consolidated  financial  statements).  In  our  opinion,  the  consolidated
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its
operations and its cash flows for each of the years in the two‑year period ended December 31, 2020, in conformity with U.S. generally accepted accounting
principles.

Basis for Opinion

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

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

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

We have served as the Company’s auditor since 2017.

XERIS PHARMACEUTICALS, INC.
Notes to Consolidated Financial Statements
December 31, 2020

Note 1. Organization and Nature of the Business

Nature of business

Xeris  Pharmaceuticals,  Inc.  ("Xeris"  or  the  "Company")  is  a  specialty  pharmaceutical  company  that  was  incorporated  in  Delaware  in  2005.  Xeris  is
dedicated to the development of ready-to-use injectable and infusible drug formulations that address important unmet medical needs, are easier to use by
patients, caregivers and health practitioners, and reduce costs for payors and the healthcare system.

Since its inception, the Company has devoted substantially all of its resources to research and development initiatives, undertaking preclinical studies of its
product  candidates,  conducting  clinical  trials  of  its  most  advanced  product  candidates,  organizing  and  staffing  the  Company,  raising  capital  and
commercializing its first product, Gvoke®, which was approved by the FDA in September 2019. Gvoke delivers ready-to-use glucagon via a commercially
available pre-filled syringe or auto-injector for the treatment of severe hypoglycemia, a potentially life-threatening condition. The Company commercially
launched Gvoke pre-filled syringe ("Gvoke PFS") in November 2019 and auto-injector ("Gvoke HypoPen ") in July 2020. The Company has financed its
operations primarily through the issuance of its common stock, convertible debt, convertible preferred stock, and debt financing.

®

The  Company  has  incurred  operating  losses  since  inception  and  has  an  accumulated  deficit  of  $337.4  million  as  of  December  31,  2020.  The  Company
expects to continue to incur net losses for at least the next 12 months. Based on the Company’s current operating plans and existing working capital at
December 31, 2020, the Company believes its cash resources are sufficient to sustain operations and capital expenditure requirements for at least the next
12 months.

The  Company  is  subject  to  a  number  of  risks  similar  to  other  specialty  pharmaceutical  companies,  including,  but  not  limited  to,  successful
commercialization and market acceptance of its products and any future products, if and when approved, successful development of its product candidates,
the development of new technological innovations by its competitors, and protection of intellectual property.

The  ongoing  global  outbreak  of  the  novel  coronavirus  disease  (“COVID-19”)  has  resulted  in  significant  governmental  measures  being  implemented  to
control the spread of the virus and has caused the Company to modify its business practices (including remote work for most of its employees). While we
cannot predict their scope and severity, these developments and measures could materially and adversely affect our business, our results of operations and
our financial condition. We are closely monitoring the impact of the COVID-19 pandemic on all aspects of our business and are taking steps to minimize its
impact  on  our  business.  However,  the  extent  to  which  COVID-19  impacts  our  business,  results  of  operations  or  financial  condition  will  depend  on  the
extent and severity of the continued spread of COVID-19 globally, the effectiveness of actions taken to contain the pandemic or treat its impact, and the
resulting economic consequences, among others. Furthermore, if we or any of the third parties with whom we engage were to experience shutdowns or
other  business  disruptions,  our  ability  to  conduct  our  business  in  the  manner  and  on  the  timelines  presently  planned  could  be  materially  or  negatively
affected, which could have a material adverse impact on our business, results of operations and financial condition.

Basis of presentation

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).
In the opinion of management, the accompanying consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments,
considered necessary for a fair presentation of the Company’s financial position and its results of operations and cash flows for the periods presented. The
results of operations for such periods are not necessarily indicative of the results that may be expected for any future period.

Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting
Standards Update (“ASU”) issued by the Financial Accounting Standards Board (“FASB”).

Basis of Consolidation

These consolidated financial statements include the financial statements of Xeris Pharmaceuticals, Inc. and its subsidiary, Xeris Pharmaceuticals Australia
Pty Ltd. All intercompany transactions have been eliminated.

Note 2. Summary of Significant Accounting Policies

The accompanying financial statements have been prepared in conformity with GAAP. Any reference in these notes to applicable guidance is meant to refer
to GAAP as found in the ASC and ASUs of the FASB.

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, liabilities, revenues and expenses included in the financial statements and accompanying notes. Actual results could differ from those
estimates.

Revenue recognition

The Company applies the guidance in ASC 606 to all contracts with customers within the scope of the standard. The Company sells its product, Gvoke,
which is available in two presentations, a pre-filled syringe (Gvoke PFS) and an auto-injector (Gvoke HypoPen), primarily to pharmaceutical wholesalers.
These wholesalers then resell the Company’s products to their customers, such as retail pharmacies. In addition, the Company enters into arrangements
with payors, group purchasing organizations, and healthcare providers that provide for government-mandated or privately-negotiated rebates, chargebacks
and discounts related to the Company’s products. The Company currently sells Gvoke in the U.S. only.

Revenue is recognized when the Company's customer (e.g., a wholesaler) obtains control of promised goods or services, which is when our obligations
under the terms of the contract with the customer are satisfied, based on the consideration the Company expects to receive in exchange for those goods or
services. The estimated net sales price is generally based upon a list or fixed price less estimates of variable consideration (e.g., patient copay assistance,
prompt payment and other discounts, payor rebates, chargebacks, service fees and product returns). The estimates of variable consideration are subject to a
constraint  such  that  some  or  all  of  the  estimated  amount  of  variable  consideration  will  only  be  included  in  the  transaction  price  to  the  extent  that  it  is
probable  that  a  significant  reversal  of  revenue  will  not  occur  when  the  uncertainty  associated  with  the  variable  consideration  is  subsequently  resolved.
Estimating variable consideration and the related constraint requires the use of significant management judgment and other market data.

Net  sales  represent  gross  product  sales  less  estimated  allowances  for  patient  copay  assistance  programs,  prompt  payment  and  other  discounts,  payor
rebates, chargebacks, service fees, and product returns, all of which are recorded at the time of sale to the pharmaceutical wholesaler or other customer. The
Company applies significant judgments and estimates in determining some of these allowances. If actual results differ from its estimates, the Company will
be required to make adjustments to these allowances in the future.

    Patient Copay Assistance Program

The Company offers a savings program to commercially insured patients under which the cost of a prescription to a patient is discounted. The
Company  reimburses  pharmacies  for  this  discount  through  a  third-party  vendor.  The  Company  records  an  accrual  to  reduce  gross  sales  for  the
estimated  copay  on  units  sold  to  wholesalers  and  other  customers.  The  estimate  is  based  on  estimated  percentages  of  products  that  will  be
prescribed to qualified patients, expected patient utilization of the discount program, average assistance paid based on reporting from the third-
party vendor as well as industry data and estimated levels of inventory in the distribution channel. Accrued copay fees are recorded as a reduction
of revenue and included in accrued trade discounts and rebates on the consolidated balance sheets.

    Prompt Payment Discounts

As  an  incentive  for  prompt  payment,  the  Company  offers  a  discount  to  most  customers.  The  Company  expects  that  all  eligible  customers  will
comply  with  the  contractual  terms  to  earn  the  discount,  and,  therefore,  we  accrue  the  discount  on  all  eligible  sales.  The  Company  records  the
discount as an allowance against trade accounts receivable on the consolidated balance sheets and as a reduction of revenue.

108

XERIS PHARMACEUTICALS, INC.
Notes to Consolidated Financial Statements
December 31, 2020

    Commercial Rebates

The  Company  contracts  with  certain  private  payor  organizations,  primarily  insurance  companies  and  pharmacy  benefit  managers,  to  provide
rebates  with  respect  to  utilization  of  Gvoke  and  contracted  formulary  status.  The  Company  accrues  estimated  rebates  based  on  contract  rates,
estimated percentages of products that will be prescribed to qualified patients and estimated levels of inventory in the distribution channel and
records the rebate as a reduction of revenue. Accrued commercial rebates are included in accrued trade discounts and rebates on the consolidated
balance sheets.

    Government Rebates

The Company participates in certain federal and state government rebate programs such as the Medicaid Drug Rebate Program, TRICARE Retail
Refunds  Program,  and  Medicare  Part  D  Program.  The  Company  accrues  estimated  rebates  and  discounts  based  on  estimated  percentages  of
product sold to qualified patients, estimated rebate percentages and estimated levels of inventory in the distribution channel that will be prescribed
to qualified patients and records the rebates as a reduction of revenue. Accrued government rebates are included in accrued trade discounts and
rebates on the consolidated balance sheets.

    Chargebacks

The  Company's  arrangements  with  certain  commercial  and  government  entities  allow  them  to  buy  their  products  directly  from  wholesalers  at
specific prices. These entities purchase products through wholesalers at the discounted price, and the wholesalers charge the difference between
their acquisition cost and the discounted price back to the Company. The Company accrues estimated chargebacks based on estimated percentages
of products sold to these entities, contract prices, and estimated levels of inventory in the distribution channel and records the chargebacks as a
reduction of revenue. Accrued chargebacks are recorded as an allowance against trade receivables on the consolidated balance sheets.

    Service Fees

The Company records service fees paid to its wholesaler customers for distribution and inventory management services as a reduction to revenue.
The  Company  accrues  estimated  service  fees  based  on  contractually  determined  amounts.  Accrued  service  fees  are  included  in  accrued  trade
discounts and rebates on the consolidated balance sheets.

    Product Returns

Consistent with industry practice, the Company's customers generally have the right to return product during the period beginning six months prior
to its expiration date and up to one year after its expiration date. As the Company's products are newly launched and the Company does not have a
history  of  product  returns,  the  Company  estimates  the  provision  for  returns  based  on  factors  related  to  the  launch  of  its  products,  third-party
industry data for comparable products in the market and estimated channel inventory data. As the Company distributes its products and establishes
historical sales over a longer period of time, it will be able to place more reliance on historical purchasing and return patterns of its customers
when evaluating its reserves for product returns. In a reporting period, the Company may decide to constrain revenue for product returns based on
information from various sources, including channel inventory levels, inventory dating, prescription data, the expiration dates of product currently
being shipped, price changes of competitive products and introductions of generic products. While the Company believes that its returns reserve is
sufficient to avoid a significant reversal of revenue in future periods, if it were to increase or decrease the rate by 1%, it would have a $0.2 million
impact  on  revenue  in  the  year  ended  December  31,  2020.  The  Company  records  estimated  sales  returns  in  accrued  returns  reserve  on  the
consolidated balance sheets and as a reduction of revenue.

Bad debt expense

The Company’s products are primarily sold to wholesalers. The Company monitors its accounts receivable balances to determine the impact, if any, of such
factors as changes in customer concentration, credit risk and the realizability of its accounts receivable, and records a bad debt reserve when applicable.

Concentration of credit risk

For the years ended December 31, 2020 and 2019, three customers accounted for 92% and 94% of the Company’s gross sales, respectively. These same
three customers accounted for 98% and 97% of the trade accounts receivable at December 31, 2020 and December 31, 2019, respectively.

Cost of Goods Sold

Cost of goods sold includes primarily product costs, which include all costs directly related to the purchase of raw materials, charges from our contract
manufacturing organizations, and manufacturing overhead costs, as well as shipping and distribution charges.  Cost of goods sold also includes losses on
excess,  slow-moving  or  obsolete  inventory  and  inventory  purchase  commitments,  if  any.  Manufacturing  costs  for  Gvoke  incurred  prior  to  approval  and
initial commercialization were expensed as research and development expenses.

Segment reporting

Operating segments are identified as components of an enterprise for which separate discrete financial information is available and utilized by the chief
operating decision maker in making decisions regarding resource allocation and assessing performance. The Company operates in one segment and, other
than having conducted certain clinical trials and applied for and received marketing approval for Ogluo outside the United States, all of the Company’s
operations are in the United States.

Cash and cash equivalents

The  Company  considers  all  demand  deposits  with  financial  institutions  and  highly  liquid  investments  with  an  original  maturity  of  three  months  or  less
when purchased to be cash equivalents.

Inventories

Inventories  are  stated  at  the  lower  of  cost  or  net  realizable  value,  using  the  first-in,  first-out  convention.    Inventories  consist  of  raw  materials,  work  in
process and finished goods. The Company has entered into manufacturing and supply agreements for the manufacture or purchase of raw materials and
production  supplies.  The  Company’s  inventories  include  the  direct  purchase  cost  of  materials  and  supplies,  charges  from  our  contract  manufacturing
organizations and manufacturing overhead costs. The Company reviews its inventory balance quarterly to assess if it has obsolete or excess inventory and
records a charge to cost of goods sold if and when applicable. Manufacturing costs for Gvoke prior to approval and commercialization were expensed as
research and development expenses.

Prepaid expenses and other current assets

Prepaid expenses and other current assets include prepaid expenses for general business purposes, which are stated at cost and amortized on a straight-line
basis  over  the  related  period  of  benefit.  Prepaid  expenses  also  include  supplies  and  materials  used  in  several  development  projects.  These  supplies  and
materials are expensed as they are consumed.

Investments

The Company classifies its investments in debt securities as available-for-sale investments. Investments classified as short-term on the balance sheets have
original maturities of greater than 90 days but less than one year.

Investments in available-for-sale securities are reported at estimated fair value. Available-for-sale securities consist primarily of corporate securities, U.S.
government  securities  and  commercial  paper.  Unrealized  gains  and  losses  related  to  changes  in  the  fair  value  of  debt  securities  are  recognized  in  other
comprehensive income (loss). Changes in the fair value of available-for-sale securities impact the statements of operations and comprehensive loss only
when such securities are sold or an other-than-temporary impairment is recognized. Realized gains and losses on the sale of securities are determined by
specific  identification  of  each  security’s  cost  basis.  The  Company  regularly  reviews  its  investment  portfolio  to  determine  if  any  security  is  other-than-
temporarily impaired, which would require an impairment charge to be recorded in the period any such determination is made. The Company considers
factors such as the

110

XERIS PHARMACEUTICALS, INC.
Notes to Consolidated Financial Statements
December 31, 2020

duration, severity of and reason for the decline in value, the financial condition of the issuer and any changes thereto, the potential recovery period and
intent to sell.

Fair value of financial instruments

Fair value is the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value
determination in accordance with applicable accounting guidance requires that a number of significant judgments be made. Additionally, fair value is used
on a non-recurring basis to evaluate assets for impairment or as required for disclosure purposes by applicable accounting guidance on disclosures about
fair  value  of  financial  instruments.  Depending  on  the  nature  of  the  assets  and  liabilities,  various  valuation  techniques  and  assumptions  are  used  when
estimating fair value. The carrying amounts of certain of the Company’s financial instruments, including cash and cash equivalents, accounts receivable,
prepaid expenses and other current assets, and accounts payable, are shown at cost, which approximates fair value due to the short-term nature of these
instruments. The debt outstanding under the Amended and Restated Loan and Security Agreement (the "Amended Loan Agreement") approximates fair
value due to the variable interest rate on the debt. Items measured at fair value on a recurring basis include the Company’s investments and warrants.

Property and equipment

Property and equipment are carried at cost less accumulated depreciation. Depreciation is calculated utilizing the straight-line method over the estimated
useful lives of the respective assets:

Lab equipment
Computer equipment
Leasehold improvements
Software
Furniture and fixtures
Office equipment

Impairment of long-lived assets

5 years
3 years
Lesser of useful life or lease term
3-5 years
5 years
5 years

The  Company  periodically  evaluates  its  long-lived  assets  for  potential  impairment  in  accordance  with  ASC  Topic  360,  Property,  Plant  and  Equipment.
Potential impairment is assessed when there is evidence that events or changes in circumstances indicate that the carrying amount of an asset may not be
recovered. Recoverability of these assets is assessed based on undiscounted expected future cash flows from the assets, considering a number of factors,
including past operating results, budgets and economic projections, market trends and product development cycles. If impairments are identified, assets are
written down to their estimated fair value. The Company recognized no material impairment charges for the years ended December 31, 2020 and 2019,
respectively.

Equity financing costs

The Company capitalizes costs directly associated with equity financings until such financings are consummated, at which time such costs are recorded in
additional  paid  in  capital  against  the  gross  proceeds  of  the  equity  financings.  The  Company  recognized  $4.3  million  and  $4.5  million  of  direct  costs
associated with the public equity offerings in additional paid in capital for the years ended December 31, 2020 and 2019, respectively. Costs associated
with  the  shelf  registration  statement  on  Form  S-3,  filed  with  the  U.S.  Securities  and  Exchange  Commission's  ("SEC")  on  August  6,  2019  and  declared
effective on August 21, 2019 have been capitalized and are being reclassified to additional paid in capital on a pro rata basis when the Company completes
offerings under the shelf registration. At the end of the three-year life of the shelf registration, the remaining deferred offering costs, if any, will be charged
to the results of operations. As of December 31, 2020 and 2019, $0.2 million and $0.4 million, respectively, of such deferred costs are included in other
assets on the consolidated balance sheets.

Deferred rent

Certain of the Company’s lease agreements provide for scheduled rent increases during the lease term and also for abatement of some or all rental payments
for a period of time after the occupancy date. In addition, certain of the Company’s lease agreements provided for tenant improvement allowances whereby
the landlord funded the cost to build out the space. The Company recorded a liability for

111

XERIS PHARMACEUTICALS, INC.
Notes to Consolidated Financial Statements
December 31, 2020

such lease incentives which is being amortized to rent expense such that rent expense is recognized on a straight-line basis throughout the lease term.

Debt issuance costs

Debt  issuance  costs  incurred  in  connection  with  financing  arrangements  are  amortized  to  interest  expense  over  the  life  of  the  respective  financing
arrangement using the effective interest method. Debt issuance costs, net of related amortization, are deducted from the carrying value of the related debt.

Warrants

The Company’s warrants are classified as liabilities as they represent a financial instrument for a share of common stock. The warrants are revalued each
reporting period with the change in fair value recorded in the accompanying statements of operations until the warrants are exercised, expire, or otherwise
settled.

Research and development expenses

Research  and  development  expenses  are  expensed  as  incurred.  Research  and  development  expenses  include  salaries,  stock  compensation  and  other
personnel-related  costs,  consulting  fees,  fees  paid  for  contract  research  and  development  services  including  those  for  preclinical  and  clinical  trials,
laboratory  equipment  and  facilities  costs,  and  other  external  costs.  In  addition,  manufacturing  costs  of  products  prior  to  approval  and  initial
commercialization are expensed as research and development costs.

Nonrefundable  advance  payments  for  goods  or  services  to  be  received  in  the  future  for  use  in  research  and  development  activities  are  deferred  and
capitalized. The capitalized amounts are expensed as the related goods are received, the services are performed or the arrangement is terminated.

Stock-based compensation expense

The Company accounts for our stock-based compensation awards in accordance with ASC Topic 718, Compensation-Stock Compensation ("ASC 718").
ASC  718  requires  all  stock-based  payments,  including  stock  options,  restricted  stock  units  and  employee  stock  purchases,  to  be  recognized  in  the
statements  of  operations  based  on  their  grant  date  fair  values.  The  Company  estimates  the  grant  date  fair  value  of  each  option  award  using  the  Black-
Scholes option-pricing model. The use of the Black-Scholes option-pricing model requires management to make assumptions with respect to the expected
term of the option, the expected volatility of the common stock consistent with the expected life of the option, the risk-free interest rate and the expected
dividend yield of the common stock. Restricted stock units are valued based on the fair market value of the Company’s common stock on the date they
were granted. The Company recognizes stock-based compensation expense equal to the grant date fair value of stock options, restricted stock units and
employee stock purchases on a straight-line basis over the requisite service period. The Company accounts for forfeitures as they are incurred.

Income taxes

Income  taxes  are  recorded  in  accordance  with  ASC  740,  Income  Taxes  (“ASC  740”),  which  provides  for  deferred  taxes  using  an  asset  and  liability
approach. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the
financial statements or tax returns. The Company determines its deferred tax assets and liabilities based on differences between financial reporting and tax
bases of assets and liabilities, which are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.
Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will
not be realized.

The  Company  accounts  for  uncertain  tax  positions  in  accordance  with  the  provisions  of  ASC  740.  When  uncertain  tax  positions  exist,  the  Company
recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit
will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances.
The  Company's  policy  is  to  include  interest  and  penalties  related  to  uncertain  tax  positions,  if  any,  within  the  provision  for  taxes  in  the  statements  of
operations and comprehensive loss. For the years ended December 31, 2020 and 2019, the Company did not accrue any interest or penalties on uncertain
tax positions.

Foreign currency translation

Our functional currency is the United States Dollar. Monetary assets and liabilities of our non-US subsidiary are remeasured using the exchange rate in
effect at the end of the period. Costs in local currency are remeasured using the average exchange rate for the period. The resulting remeasurement gains
and losses are included in other comprehensive income (loss).

Comprehensive loss

Comprehensive loss is defined as the change in equity during a period from transactions and other events, excluding changes resulting from investments
from  owners  and  distributions  to  owners.  Comprehensive  loss  includes  net  loss,  unrealized  (gains)  losses  on  available-for-sale  investments  and  foreign
currency translation adjustments.

Reclassifications

Certain prior period amounts on the balance sheet have been reclassified to conform to the current year presentation. These reclassifications had no impact
on current assets, total assets, current liabilities or total liabilities.

New accounting pronouncements

Recently issued accounting pronouncements

In  August  2020,  the  FASB  issued  ASU  2020-06,  Debt—Debt  with  Conversion  and  Other  Options  (Subtopic  470-20)  and  Derivatives  and  Hedging—
Contracts  in  Entity’s  Own  Equity  (Subtopic  815-40):  Accounting  for  Convertible  Instruments  and  Contracts  in  an  Entity’s  Own  Equity.  This  standard
eliminates certain accounting models to simplify the accounting for convertible instruments, expands the disclosure requirements related to the terms and
features  of  convertible  instruments,  and  amends  the  guidance  for  the  derivatives  scope  exception  for  contracts  settled  in  an  entity’s  own  equity.  This
standard enhances the consistency of earnings-per-share ("EPS") calculations by requiring that an entity use the if-converted method and that the effect of
potential share settlement be included in diluted EPS calculations and disclosures. This standard will be effective for the Company for annual and interim
periods beginning after December 15, 2023. Early adoption is permitted but not earlier than periods beginning after December 15, 2020. The Company is
currently evaluating the impact the adoption of this new standard will have on its financial statements and disclosures.

In March 2020, the FASB issued ASU 2020-04, Reference  Rate  Reform  (Topic  848):  Facilitation  of  the  Effects  of  Reference  Rate  Reform  on  Financial
Reporting. This standard provides optional expedients for application of GAAP, if certain criteria are met, to contracts and other transactions that reference
LIBOR or other reference rates that are expected to be discontinued because of reference rate reform. The amendments in this update are effective through
December 31, 2022. The Company does not currently expect the adoption of this new standard to have a material impact on its financial statements.

In  December  2019,  the  FASB  issued  ASU  2019-12,  Income  Taxes  (Topic  740):  Simplifying  the  Accounting  for  Income  Taxes.  This  standard  eliminates
certain exceptions in the current guidance related to the approach for intraperiod tax allocation and the methodology for calculating income taxes in an
interim  period  and  amends  other  aspects  of  the  guidance  to  help  clarify  and  simplify  U.S.  GAAP.  This  standard  will  be  effective  for  the  Company  for
annual  periods  beginning  after  December  15,  2021  and  interim  periods  within  fiscal  years  beginning  after  December  15,  2022,  with  early  adoption
permitted. The Company does not currently expect the adoption of this new standard to have a material impact on its financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,
as further updated by ASU 2018-19, 2019-04, 2019-05, 2019-10 and 2020-03. This standard requires entities to estimate an expected lifetime credit loss on
financial assets ranging from short-term trade accounts receivable to long-term financings and report credit losses using an expected losses model rather
than the incurred losses model that was previously used and establishes additional disclosures related to credit risks. For available-for-sale debt securities
with unrealized losses, the standard will require allowances to be recorded instead of reducing the amortized cost of the investment. This standard limits the
amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and requires the
reversal  of  previously  recognized  credit  losses  if  fair  value  increases.  This  standard  will  be  effective  for  the  Company  for  annual  and  interim  periods
beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact the adoption of this new standard will
have on its financial statements.

December 31, 2020

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard requires lessees to record a right-of-use asset and a lease liability
for all leases with a term of greater than twelve months regardless of their classification. Leases will be classified as either operating or finance leases under
the new guidance. Operating leases will result in straight-line expense in the income statement, similar to current operating leases, and finance leases will
result  in  more  expense  being  recognized  in  the  earlier  years  of  the  lease  term,  similar  to  current  capital  leases.  The  FASB  has  recently  extended  the
effective date of this standard for certain companies. This standard will be effective for the Company for fiscal years beginning after December 15, 2021
and  interim  periods  within  fiscal  years  beginning  after  December  15,  2022.  The  Company  is  currently  evaluating  the  impact  the  adoption  of  this  new
standard will have on the financial statements and related disclosures; however, since the Company is a lessee to certain leases for property whose terms
exceed twelve months, it expects, once adopted, to report assets and liabilities related to these leases on its balance sheet.

In June 2020, the Company completed a public offering of $86.3 million aggregate principal amount of the Company's 5.00% Convertible Senior Notes
due 2025 (the "Convertible Notes"), including $11.3 million pursuant to the underwriters' option to purchase additional notes which was exercised in full in
July  2020.  The  Company  incurred  debt  issuance  costs  of  $5.1  million  in  connection  with  the  issuance  of  the  Convertible  Notes.  The  Company  used
$20.0 million and $4.2 million of the net proceeds from the sale to prepay a portion of the principal amount on the Term A Loan (as defined below) and the
remaining amount of borrowings outstanding under the PPP Loan (as defined below), respectively.

The Convertible Notes are governed by the terms of a base indenture for senior debt securities, as supplemented by the first supplemental indenture thereto,
each dated as of June 30, 2020, by and between the Company and U.S. Bank National Association, as trustee. The Convertible Notes bear cash interest at
the rate of 5.00% per annum, payable semi-annually in arrears on January 15 and July 15 of each year, beginning on January 15, 2021, to holders of record
at the close of business on the preceding January 1 and July 1, respectively. The Convertible Notes will mature on July 15, 2025, unless earlier converted or
redeemed or repurchased by the Company.

At  any  time  before  the  close  of  business  on  the  second  scheduled  trading  day  immediately  before  the  maturity  date,  holders  of  Convertible  Notes  may
convert their Convertible Notes at their option into shares of the Company’s common stock, together, if applicable, with cash in lieu of any fractional share,
at the then-applicable conversion rate. The conversion rate for the Convertible Notes will initially be 326.7974 shares of the Company’s common stock per
$1,000  principal  amount  of  Convertible  Notes,  which  represents  an  initial  conversion  price  of  approximately  $3.06  per  share  of  common  stock,  and  is
subject  to  adjustment  under  the  terms  of  the  Convertible  Notes.  In  the  event  of  certain  circumstances,  the  Company  will  increase  the  conversion  rate,
provided that the conversion rate will not exceed 367.6470 shares of the Company's common stock per $1,000 principal amount of Convertible Notes.

In the second half of 2020, $8.4 million in principal amount of Convertible Notes were converted into 2,736,591 shares of the Company’s common stock at
the conversion rate of 326.7974 shares per $1,000 principal amount of Convertible Notes. Additionally, in the fourth quarter of 2020, the Company entered
into  separate,  privately  negotiated  exchange  agreements  with  certain  holders  of  Convertible  Notes  to  exchange  $30.7  million  in  principal  amount  of
Convertible Notes for 10,435,200 shares of the Company’s common stock. The Company recognized a $2.6 million loss related to the convertible note
exchange transactions.

The  Convertible  Notes  are  senior,  unsecured  obligations  and  are  equal  in  right  of  payment  with  the  Company's  existing  and  future  senior,  unsecured
indebtedness,  senior  in  right  of  payment  to  its  future  indebtedness,  if  any,  that  is  expressly  subordinated  to  the  Convertible  Notes,  and  effectively
subordinated to its existing and future secured indebtedness to the extent of the value of the collateral securing that indebtedness. The Convertible Notes are
structurally  subordinated  to  all  existing  and  future  indebtedness  and  other  liabilities,  including  trade  payables,  and  (to  the  extent  the  Company  is  not  a
holder thereof) preferred equity, if any, of its subsidiaries.

Senior Secured Loan Facility

In  February  2018,  the  Company  entered  into  the  Loan  and  Security  Agreement,  dated  as  of  February  28,  2018  (as  amended,  the  “Original  Loan
Agreement”), with Oxford Finance LLC, as the collateral agent and a lender (“Oxford”), and Silicon Valley Bank, as a lender (“SVB”, and together with
Oxford, the “Lenders”), which provided for a senior secured loan facility of up to an aggregate principal amount of $45.0 million. The first tranche of $20.0
million was drawn down in February 2018 (the "2018 Term A Loan"). The second tranche of $15.0 million was drawn down in September 2018 (the "2018
Term B Loan"). The Company also issued warrants to the Lenders to purchase common stock, which is further discussed in Note 8, "Warrants."

In September 2019, the Company entered into an Amended and Restated Loan and Security Agreement (the "Loan Agreement") with the Lenders which
amended and restated the Original Loan Agreement, in its entirety. The Loan Agreement provided for the Lenders to extend up to $85.0 million in term
loans to the Company in three tranches. The initial tranche of $60.0 million (the “Term A Loan”) was drawn down in September 2019. Additional tranches
of $15.0 million (the “Term B Loan”) and $10.0 million (the “Term C Loan”) will become available to the Company if certain revenue targets are achieved
prior  to  March  31,  2021  and  June  30,  2021,  respectively.  The  Company  currently  does  not  anticipate  that  such  revenue  targets  will  be  achieved.  In
conjunction  with  the  execution  of  the  Loan  Agreement,  the  2018  Term  A  Loan  and  2018  Term  B  Loan  were  repaid  and  the  final  payment  fee  of  $2.3
million was paid.

Effective April 21, 2020, the Company entered into that certain First Amendment to the Amended and Restated Loan and Security Agreement with the
Lenders  (the  “First  Amendment”)  to  amend  the  Loan  Agreement  to  allow  the  Company  to  incur  indebtedness  under  the  U.S.  Small  Business
Administration (the “SBA”) Paycheck Protection Program (the “PPP”) enabled by the Coronavirus Aid, Relief and Economic Security Act of 2020 (the
“CARES Act”) in the amount of $5.1 million (the “PPP Loan”).

On June 30, 2020, the Company entered into that certain Second Amendment to the Amended and Restated Loan and Security Agreement with the Lenders
(the "Second Amendment") to amend the Loan Agreement to provide for the Lenders’ consent to and allow for the Company's underwritten public offering
of  the  Company's  5.00%  Convertible  Senior  Notes  due  2025  and  permit  the  Company  to  prepay  its  PPP  Loan  in  full.  The  Second  Amendment  also
provided for the extension of the interest-only payment period through December 31, 2021, after which the term loans will be payable in 30 equal monthly
installments.  However,  if  the  Company  achieves  a  certain  revenue  milestone  prior  to  January  1,  2022,  then  the  period  for  interest-only  payments  is
extended through September 30, 2022, after which the term loans will be payable in 21 equal monthly installments. In addition the Second Amendment
further provided for an extension of the maturity date from June 1, 2023 to June 1, 2024. After repayment, no loans may be re-borrowed.

Pursuant to the Second Amendment, the Company prepaid a portion of the Term A Loan equal to the sum of (i) $20.0 million, plus all accrued and unpaid
interest as of the date of the Second Amendment, (ii) the applicable final payment fee of $0.6 million, (iii) the applicable prepayment fee of $0.3 million
and (iv) all outstanding Lenders’ expenses as of the date of the Second Amendment. Additionally, the Company is required to maintain a minimum balance
of $5.0 million in unrestricted cash at SVB at all times and to pay an amendment fee of up to $0.1 million at the earliest to occur of the maturity date,
acceleration of any term loan, or prepayment of any term loan amount.

On August 5, 2020, the Company entered into that certain Third Amendment to the Amended and Restated Loan and Security Agreement with the Lenders
(the “Third Amendment”) to amend the Loan Agreement to (i) amend the definition of “Permitted Indebtedness” to include a new standby letter of credit in
an amount not to exceed $0.4 million issued to the landlord for the Company’s new leased laboratory space and (ii) permit the sale of certain equipment
related to the relocation of the Company’s research and development laboratory from San Diego to Chicago.

On  October  23,  2020,  the  Company  entered  into  that  certain  Fourth  Amendment  to  the  Amended  and  Restated  Loan  and  Security  Agreement  with  the
Lenders (the "Fourth Amendment") to amend the Loan Agreement (as amended, supplemented or otherwise modified from time to time, including by that
certain First Amendment, Second Amendment, Third Amendment and Fourth Amendment, collectively, the "Amended Loan Agreement") to provide an
additional tranche of $3.5 million (the “Term D Loan”, and, together with the Term A Loan, Term B Loan, and Term C Loan, the "Term Loan"), available
upon execution. The Term D Loan of $3.5 million was drawn in November 2020 and will be payable under the same payment terms as the Term Loans.
After repayment, the loan may not be re-borrowed.

Pursuant  to  the  Amended  Loan  Agreement,  the  Company  has  provided  a  first  priority  security  interest  in  substantially  all  of  the  Company’s  assets,
including intellectual property, subject to certain limited exceptions.

All of the loans incur interest at a floating per annum rate in an amount equal to the sum of 6.25% plus the greater of (a) 2.43% and (b) the thirty-day U.S.
Dollar LIBOR rate. For the period from the funding date of the Term A Loan through and including December 31, 2020, the interest rate was 8.68%. The
remaining balance of unamortized debt issuance costs related to the Loan Agreement and the additional debt issuance costs incurred in conjunction with the
Second Amendment have been reflected as a direct reduction to the loan balance and are being amortized to interest expense over the remaining life of the
loan using the effective interest method.

The  Amended  Loan  Agreement  allows  the  Company  to  voluntarily  prepay  the  outstanding  amounts  thereunder,  but  not  less  than  $2.0  million  of  the
outstanding principal at any time. The Company is subject to a prepayment fee equal to 1.50% of the principal amount being prepaid. Also, a final payment
fee of 3.0% multiplied by the amount to be repaid is due upon the earliest to occur of the maturity date of the Amended Loan Agreement, the acceleration
of the amounts outstanding under the Amended Loan Agreement or prepayment of such borrowings and is recorded in other liabilities on the consolidated
balance sheets.

The Amended Loan Agreement contains customary representations and warranties, events of default (including an event of default upon a material adverse
change of the Company) and affirmative and negative covenants, including, among others, covenants that limit or restrict the Company’s ability to incur
additional indebtedness, grant liens, merge or consolidate, make acquisitions, pay dividends or other distributions or repurchase equity, make investments,
dispose of assets and enter into certain transactions with affiliates, in each case subject to certain exceptions.

Paycheck Protection Program Loan

In April 2020, the Company entered into the SBA PPP Note with SVB (the “PPP Lender”) for the PPP Loan in the amount of $5.1 million, enabled by the
CARES Act to retain employees, maintain payroll and make lease and utility payments in accordance with the relevant terms and conditions of the CARES
Act. The Company repaid $0.9 million of the PPP Loan in May 2020 and the remaining $4.2 million on June 30, 2020.

For the year ended December 31, 2020, the Company recognized interest expense of $10.7 million, of which $1.0 million related to the amortization of
debt issuance costs. Included in such interest expense are a loss on conversion of convertible debt and a loss on extinguishment of debt of $2.6 million and
$0.7 million, respectively. For the year ended December 31, 2019, the Company recognized interest expense of $7.2 million, of which $0.9 million related
to the amortization of debt issuance costs. Included in such interest expense is a loss on extinguishment of debt of $2.3 million relating to the write-off of
the remaining balance of unamortized debt issuance costs associated with the Original Loan Agreement.

Note 7. Stockholders' Equity

The  Company’s  authorized  shares  of  stock  of  160.0  million  are  divided  into  150.0  million  shares  of  common  stock,  par  value  $0.0001  per  share,  and
10.0  million  shares  of  preferred  stock,  par  value  $0.0001  per  share.  At  December  31,  2020  none  of  the  10.0  million  shares  of  preferred  stock  were
outstanding, and the Company has no present plans to issue any shares of preferred stock. The Company’s board of directors has the authority, without
action by the Company’s stockholders, to designate and issue the preferred stock in one or more series and to designate the rights, preferences, limitations
and privileges of each series of preferred stock, which may be greater than the rights of the Company’s common stock.

The Company has not paid any cash dividends on its common stock during the periods presented.

In  February  2019,  the  Company  completed  an  equity  offering  of  its  common  stock  pursuant  to  a  registration  statement  on  Form  S-1,  as  amended.  The
Company sold an aggregate of 5,996,775 shares of common stock at a price of $10.00 per share, including 116,775 shares of common stock pursuant to the
exercise of the underwriters' option to purchase additional shares. Net proceeds from the equity offering were $55.5 million after deducting underwriting
discounts and commissions as well as other public offering expenses.

On  August  6,  2019,  the  Company  filed  a  shelf  registration  statement  on  Form  S-3  with  the  SEC,  which  covers  the  offering,  issuance  and  sale  by  the
Company of up to an aggregate of $250.0 million of its common stock, preferred stock, debt securities, warrants and/or units (the "Shelf"). The Company
simultaneously entered into a Sales Agreement with Jefferies LLC, as sales agent, to provide for the offering, issuance and sale by the Company of up to
$50.0 million of its common stock from time to time in "at-the-market" offerings under the Shelf. The Shelf was declared effective by the SEC on August
21, 2019. In December 2019, the Company sold an aggregate of 204,427 shares of common stock under the Shelf for net proceeds of $1.7 million after
deducting selling commissions as well as other public offering expenses.

In February 2020, the Company completed an equity offering of its common stock pursuant to the Shelf. The Company sold an aggregate of 10,299,769
shares  of  common  stock  at  a  price  of  $4.15  per  share,  including  1,299,769  shares  pursuant  to  the  underwriters’  option  to  purchase  additional  shares  of
common stock. Net proceeds from the equity offering were approximately $39.9 million after deducting underwriting discounts and commissions as well as
other public offering expenses.

In June 2020, the Company completed an equity offering of its common stock pursuant to the Shelf. The Company sold an aggregate of 8,510,000 shares of
common stock at a price of $2.72 per share, including 1,110,000 shares pursuant to the underwriters' option to purchase additional shares which was fully
exercised in July 2020. Net proceeds from the equity offering were approximately $21.6 million after deducting underwriting discounts and commissions as
well as other public offering expenses.

In the second half of 2020, $8.4 million in principal amount of Convertible Notes were converted into 2,736,591 shares of the Company’s common stock at
the conversion rate of 326.7974 shares per $1,000 principal amount of Convertible Notes. Additionally, in the fourth quarter of 2020, the Company entered
into  separate,  privately  negotiated  exchange  agreements  with  certain  holders  of  Convertible  Notes  to  exchange  $30.7  million  in  principal  amount  of
Convertible Notes for 10,435,200 shares of the Company’s common stock.

Upon vesting and settlement of RSUs or exercise of stock options, at the election of the grantee, the Company does not collect withholding taxes in cash
from employees. Instead, the Company withholds upon settlement as RSUs vest, or as stock options are exercised, the portion of those shares with a fair
market value equal to the amount of the minimum statutory withholding taxes due. The withheld shares are accounted for as repurchases of common stock.
The Company then pays the minimum statutory withholding taxes in cash. During the year ended December 31, 2020, 31,250 RSUs vested for which 9,801
shares were withheld to cover the minimum statutory withholding taxes of $0.1 million.

Note 8. Warrants

In 2014 the Company issued 19,931 warrants (the “2014 Warrants”) to certain investors. The 2014 Warrants allow each holder to purchase one share of
common stock for $5.912. Of the 2014 Warrants, 18,512 warrants were exercised and 1,419 warrants expired. There are no 2014 Warrants outstanding as of
December 31, 2020.

As  part  of  the  Original  Loan  Agreement  discussed  in  Note  6,  "Long-term  Debt,"  the  Lenders  received  warrants  concurrent  with  the  borrowing.  The
warrants represent a right for the lender to purchase shares of the Company’s common stock at an exercise price of

118

XERIS PHARMACEUTICALS, INC.
Notes to Consolidated Financial Statements
December 31, 2020

$11.169 per share. The Company issued 53,720 warrants (the "2018 Term A Warrants") upon the drawdown of the 2018 Term A Loan in February 2018,
and the Company issued 40,292 warrants (the "2018 Term B Warrants") upon the drawdown of the 2018 Term B Loan in September 2018. There have been
no exercises of 2018 Term A Warrants or 2018 Term B Warrants.

Because the warrants are a freestanding instrument, indexed to the Company's stock, they do not meet the criteria for equity classification. Therefore, the
warrants are classified as liabilities and subject to remeasurement at each reporting period until they are exercised, expired, or otherwise settled.

The Company recognized gains (losses) of $4,000, ($8,000) and ($5,000) upon the change in fair value of the warrants during the year ended December 31,
2020 related to the 2014 Warrants, the 2018 Term A Warrants and the 2018 Term B Warrants, respectively. The Company recognized gains of $78,000,
$351,000 and $263,000 upon the change in fair value of the warrants during the year ended December 31, 2019 related to the 2014 Warrants, the 2018

The Company has non-cancellable operating leases for office and laboratory space, which expire at various times through 2033. The non-cancellable lease
agreements provide for monthly lease payments which increase during the term of each lease agreement.

In the third quarter of 2020, the Company signed a lease to occupy a research and development laboratory site in Chicago, Illinois in conjunction with the
Company's plan to relocate such activities from the current San Diego site in the fourth quarter of 2020. The future minimum lease payments of the new
lease are approximately $0 in 2021, $0.5 million in 2022, $0.7 million in 2023, $0.7 million in 2024, $0.7 million in 2025, and $6.5 million in 2026 and
thereafter. In conjunction with the new lease, the Company assigned its lease for the San Diego site to a third party in the fourth quarter of 2020. Such
assignment released the Company from any further minimum lease payment obligations for that site.

Future minimum lease payments under operating leases at December 31, 2020 are as follows (in thousands):

Litigation

From  time  to  time,  the  Company  may  become  involved  in  various  legal  actions  arising  in  the  ordinary  course  of  business.  As  of  December  31,  2020,
management was not aware of any existing, pending or threatened legal actions that would have a material impact on the financial position or results of
operations of the Company.

Note 10. Restructuring Costs

In the third quarter of 2020, the Company commenced a plan to relocate its research and development laboratory from San Diego to Chicago. The costs
associated with the plan include employee termination and relocation costs and other facility exit costs. The Company expects to incur total restructuring
costs of approximately $2.3 million related to the plan. Costs of $1.7 million were incurred in the year ended December 31, 2020, of which $1.0 million is
included in research and development expenses, $0.6 million is included in selling, general and administrative expenses, and $0.1 million is included in
costs  of  goods  sold  in  the  consolidated  statements  of  operations  and  comprehensive  loss.  The  Company  anticipates  that  the  restructuring  will  be
substantially complete by the end of the fourth quarter of 2021. The restructuring reserve is included in other accrued liabilities in the consolidated balance
sheet.

Note 11. Stock Compensation Plan

In 2011, the Company adopted the 2011 Stock Option Issuance Plan (the “2011 Plan”) and subsequently amended it to authorize the Board of Directors to
issue up to 4,714,982 incentive stock option and non-qualified stock option awards.

The  2018  Stock  Option  and  Incentive  Plan  (the  "2018  Plan")  was  adopted  by  the  Board  of  Directors  in  April  2018  and  approved  by  the  Company's
stockholders in June 2018 to award up to 1,822,000 shares of common stock. This plan became effective on the date immediately prior to the effectiveness
of the Company's IPO registration statement. The 2018 Plan replaced the 2011 Plan as the Board of Directors decided not to make additional awards under
the 2011 Plan following the closing of the IPO, which occurred in June 2018. The 2018 Plan allows the compensation committee to make equity-based and
cash-based incentive awards to the Company's officers, employees, directors and other key persons (including consultants). No grants of stock options or
other awards may be made under the 2018 Plan after the tenth anniversary of the effective date.

The 2018 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning
on  January  1,  2019,  and  each  January  1  thereafter,  by  4%  of  the  outstanding  number  of  shares  of  our  common  stock  on  the  immediately  preceding
December 31, or such lesser number of shares as determined by the compensation committee. This number is subject to adjustment in the event of a stock
split,  stock  dividend  or  other  change  affecting  the  Company's  common  stock.  On  January  1,  2020  and  2019,  the  number  of  shares  of  common  stock
available for issuance under the 2018 Plan was automatically increased by 1,088,580 shares and 835,728 shares, respectively. As of December 31, 2020,
there were 609,757 shares of common stock available for future issuance under the 2018 plan.

The 2018 Employee Stock Purchase Plan (the "ESPP") was adopted by the Board of Directors in April 2018 and approved by the Company's stockholders
in  June  2018  to  issue  up  to  193,000  shares  of  common  stock  to  participating  employees.  Through  the  ESPP,  eligible  employees  may  authorize  payroll
deductions of up to 15% of their compensation to purchase up to the number of shares of common stock determined by dividing $25,000 by the closing
market price of Xeris common stock on the offering date. The purchase price per share at each purchase date is equal to 85% of the lower of (i) the closing
market price per share of Xeris common stock on the employee’s offering date or (ii) the closing market price per share of Xeris common stock on the
purchase date. Each offering period has a six-month duration and purchase interval with a purchase date of the last business day of June and December
each year.

XERIS PHARMACEUTICALS, INC.
Notes to Consolidated Financial Statements
December 31, 2020

This plan became effective on the date immediately prior to the effectiveness of the Company's IPO registration statement. The ESPP provides that the
number  of  shares  reserved  and  available  for  issuance  will  automatically  increase  each  January  1,  beginning  on  January  1,  2019  and  each  January  1
thereafter  through  January  1,  2028,  by  the  least  of  (i)  1%  of  the  outstanding  number  of  shares  of  our  common  stock  on  the  immediately  preceding
December 31; (ii) 386,000 shares or (iii) such lesser number of shares as determined by the ESPP administrator. On January 1, 2020 and 2019, the number
of  shares  of  common  stock  available  for  issuance  under  the  ESPP  increased  by  272,145  shares  and  208,932  shares,  respectively.  The  number  of  shares
reserved under the ESPP is subject to adjustment in the event of a stock split, stock dividend or other change affecting the Company's common stock. The
Company issued 292,804 shares at a weighted average price of $2.29 per share during the year ended December 31, 2020. As of December 31, 2020, there
were 307,666 shares available for issuance under the ESPP.

The Equity Inducement Plan (the "Inducement Plan") was adopted by the Board of Directors in February 2019. The Inducement Plan was adopted without
stockholder approval pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules. The Inducement Plan allows the Company to make stock option or restricted
stock  unit  awards  to  prospective  employees  of  the  Company  as  an  inducement  to  such  individuals  to  commence  employment  with  the  Company.  The
Company intends to use this Inducement Plan to help it attract and retain prospective employees who are necessary to support the commercial launch of
Gvoke and the expansion of the Company generally. The Company initially reserved 750,000 shares of common stock for the issuance of awards under the
Inducement Plan. This number is subject to adjustment in the event of a stock split, stock dividend or other change affecting the Company's common stock.
As of December 31, 2020, there were 263,794 shares of common stock available for future issuance under the Inducement Plan.

On October 8, 2020, the Company's stockholders, upon recommendation of the Board of Directors, approved an amendment to the Company's 2011 Plan
and  2018  Plan  to  allow  the  Company  to  permit  certain  employee  option  holders,  subject  to  specified  conditions,  to  exchange  some  or  all  of  their
outstanding options to purchase shares of the Company's common stock for a lesser number of new options to purchase shares of the Company’s common
stock (the “Option Exchange”).

On  November  10,  2020,  the  Company  filed  with  the  SEC  a  Tender  Offer  Statement  on  Schedule  TO  defining  the  terms  and  conditions  of  the  Option
Exchange. The total number of shares of common stock underlying a new option with respect to an exchanged eligible option was determined by dividing
the  number  of  shares  of  common  stock  underlying  the  exchanged  eligible  option  by  the  applicable  exchange  ratio  and  rounding  to  the  nearest  whole
number, subject to the terms and conditions described in the Exchange Offer. On December 10, 2020, the completion date of the Option Exchange, the
Company canceled the options accepted for exchange and granted 832,907 new options to purchase shares of common stock in exchange for 1,127,906
options issued under the 2011 Plan and 2018 Plan. The exercise price per share of the options granted pursuant to the Exchange Offer was $4.09 per share,
which was the closing price per share of common stock on The Nasdaq Global Select Market on the grant date of such new options. The new options will
vest and become exercisable in two equal installments following the grant date, subject to an option holder's continuous service, and expire seven years
from the grant date. On the grant date, the fair values of the options exchanged were similar to the fair values of the new options granted and, as such, the
incremental compensation cost related to the Option Exchange was not material.

Stock options are granted with an exercise price equal to the market price of the Company’s stock at the date of grant. Stock option awards typically vest
over either two, three or four years after the grant date and expire seven to ten years from the grant date.

The  fair  value  of  each  option  is  estimated  on  the  date  of  grant  using  a  Black-Scholes  option  valuation  model  that  uses  the  assumptions  noted  in  the
following table. The expected term of options represents the period of time that options granted are expected to be outstanding. The risk-free interest rate
for  periods  during  the  contractual  life  of  the  option  is  based  on  the  U.S.  Treasury  yield  curve  in  effect  at  the  time  of  grant.  The  expected  stock  price
volatility assumption is based on the historical volatilities of a peer group of publicly traded companies as well as the historical volatility of the Company's
common stock since the Company began trading subsequent to its IPO in June 2018 over the period corresponding to the expected life as of the grant date.
The expected dividend yield is based on the expected annual dividend as a percentage of the market value of the Company’s ordinary shares as of the grant
date.

Level 3: Measured based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable
from objective sources (i.e., supported by little or no market activity).

Fair  value  measurements  are  classified  based  on  the  lowest  level  of  input  that  is  significant  to  the  measurement.  The  Company’s  assessment  of  the
significance  of  a  particular  input  to  the  fair  value  measurement  requires  judgment,  which  may  affect  the  valuation  of  the  assets  and  liabilities  and  their
placement within the fair value hierarchy levels. The determination of the fair values stated below takes into account the market for its financial assets and
liabilities, the associated credit risk and other factors as required. The Company considers active markets as those in which transactions for the assets or
liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

The fair value of the Company’s warrant liabilities is based on a Black-Scholes valuation which considers the expected term of the warrants as well as the
risk-free interest rate and expected volatility of the Company's common stock.

The  Company  has  determined  that  the  warrant  liabilities'  fair  values  are  Level  3  items  within  the  fair  value  hierarchy.  The  following  table  presents  the
change in the warrant liabilities (in thousands):

Note 13. Available-for-Sale Investments

The Company classifies its investments in debt securities as available-for-sale. Debt securities are comprised of highly liquid investments with minimum
“A” rated securities and, as of December 31, 2020, consist of U.S. Treasury and agency bonds and corporate entity commercial paper and securities, all
with maturities of more than three months but less than one year at the date of purchase. Debt securities as of December 31, 2020 had an average remaining
maturity of 0.4 years. The debt securities are reported at fair value with unrealized gains or losses recorded in other comprehensive income (loss). Refer to
Note 12, "Fair Value Measurements," for information related to the fair value measurements and valuation methods utilized.

The following table represents the Company’s available-for-sale investments by major security type as of December 31, 2020 and 2019 (in thousands):

The Company reviews available-for-sale investments for other-than-temporary impairment loss periodically. The Company considers factors such as the
duration, severity of and reason for the decline in value, the potential recovery period and our intent to sell. For debt securities, we also consider whether
(i) it is more likely than not that the Company will be required to sell the debt securities before recovery of their amortized cost basis and (ii) the amortized
cost basis cannot be recovered as a result of credit losses. During the years ended December 31, 2020 and 2019, the Company did not recognize any other-
than-temporary impairment losses. All marketable securities with unrealized losses have been in a loss position for less than twelve months.

Note 14. Net Loss Per Common Share

Basic and diluted net loss per common share are determined by dividing net loss applicable to common stockholders by the weighted average common
shares outstanding during the period. For all periods presented, the shares issuable upon conversion, exercise or vesting of Convertible Notes, warrants,
stock  option  awards  and  RSUs  have  been  excluded  from  the  calculation  because  their  effects  would  be  anti-dilutive.  Therefore,  the  weighted  average
common shares outstanding used to calculate both basic and diluted net loss per common share are the same.

The Company sponsors an employee retirement plan qualifying under Section 401(k) of the Internal Revenue Code for all eligible employees in the United
States.  Employees  become  eligible  to  contribute  to  the  plan  upon  meeting  certain  age  requirements  and  30  days  of  service.  Commencing  in  2019,  the
Company began discretionary matching employee contributions up to certain limits. For the years ended December 31, 2020 and 2019, the Company made
$0.6 million and $0.4 million of matching contributions to the plan, respectively.

Defined Compensation Plan

The  Compensation  Committee  of  the  Board  of  Directors  adopted  a  deferred  compensation  plan  ("Deferred  Compensation  Plan")  in  April  2020.  The
Deferred  Compensation  Plan  allows  a  select  group  of  executive  management  and  non-employee  directors  to  defer  payment  of  certain  of  their  cash
compensation.  Participants  in  the  Deferred  Compensation  Plan  who  are  employees  may  defer  all  or  a  portion  of  their  annual  base  salaries  and  all  or  a
portion of their annual cash performance-based compensation. Participants who are non-employee directors may defer all or a portion of their annual cash
retainers.  The  participants’  elective  deferrals  are  100%  vested  immediately  and  accrue  interest  at  a  rate  of  two  percent  per  annum.  The  Deferred
Compensation Plan is unfunded and unsecured. As of December 31, 2020, the total deferred compensation liability under the Deferred Compensation Plan
was approximately $1.7 million and was recorded in other liabilities in the consolidated balance sheets.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of the assets and liabilities for financial reporting
purposes  and  the  amounts  used  for  income  tax  purposes.  A  valuation  allowance  is  required  to  be  established  or  maintained  when,  based  on  currently
available information, it is more likely than not that all or a portion of a deferred tax asset will not be realized. The guidance on accounting for income
taxes provides important factors in determining whether a deferred tax asset will be realized, including whether there has been sufficient taxable income in
recent  years  and  whether  sufficient  income  can  reasonably  be  expected  in  future  years  in  order  to  utilize  the  deferred  tax  asset.  For  the  year  ended
December 31, 2020, we have evaluated the need to maintain a valuation allowance for deferred tax assets based on our assessment of whether it is more
likely than not that deferred tax benefits will be realized through the generation of future taxable income. Appropriate consideration is given to all available
evidence, both positive and negative, in assessing the need for a valuation allowance.

Significant components of the Company’s deferred tax assets and liabilities are as follows (in thousands): 

Deferred tax assets:
   Net operating losses
   Federal research and orphan drug credits
   Stock-based compensation
   Other temporary differences
   Valuation allowance

As of December 31, 2020, the Company had federal net operating loss carryforwards of $284.8 million and various state net operating loss carryforwards
of $220.6 million. As of December 31, 2019, the Company had federal net operating loss carryforwards of $215.3 million and various state net operating
loss carryforwards of $147.5 million. Net operating loss carryforwards for U.S. federal income tax purposes that were generated prior to January 1, 2018
have a twenty-year carryforward life, and the earliest layers will begin to expire in 2025. Under the Tax Cuts and Jobs Act of 2017, federal net operating
losses incurred in 2018 and later years may be carried forward indefinitely, but the deductibility of such net operating losses is limited to 80% of the current
year’s taxable income. U.S. state net operating loss carryforwards will start to expire in 2029 for the earliest net operating loss layers to the extent there is
not sufficient state taxable income to utilize those net operating loss carryforwards.

At  December  31,  2020,  the  Company  had  $8.0  million  and  $1.7  million  of  federal  and  state  income  tax  credits,  respectively,  to  reduce  future  tax
liabilities. At December 31, 2019, the Company had $8.3 million and $1.0 million of federal and state income tax credits, respectively, to reduce future tax
liabilities. The federal income tax credits consist primarily of orphan drug credits and research and development credits. The U.S. state income tax credits
consist  primarily  of  California  and  Illinois  research  and  development  credits.  Both  the  U.S.  federal  orphan  drug  credits  and  research  and  development
credits have a twenty-year carryforward life. The U.S. federal orphan drug credits and research and development credits will both begin to expire in 2025.

The Company is required to recognize the financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the
position  will  be  sustained  upon  examination.  The  Company  accounts  for  the  uncertainty  in  income  taxes  by  utilizing  a  comprehensive  model  for  the
recognition, measurement, presentation and disclosure in financial statements of any uncertain tax positions that have been taken, or are expected to be
taken, on an income tax return. The changes in the Company's uncertain income tax positions for the years ended December 31, 2020 and 2019, excluding
interest and penalties, consisted of the following (in thousands):

Beginning balance - uncertain tax positions
   Increases related to tax positions taken during the current year
   Increases (decreases) related to tax positions taken during the prior year

For the year ended December 31, 2020, the increase in current year uncertain tax positions was attributable primarily to U.S. federal orphan drug credits
and research and development credits and the decrease related to tax positions taken during the prior year was a result of return to provision adjustments. In
the  Company’s  balance  sheet,  uncertain  tax  positions  of  $0.9  million  were  offset  against  deferred  tax  assets.  Tax  years  prior  to  2017  generally  are  not
subject to examination by the Internal Revenue Service or state or local taxing authorities.

The  Company  policy  is  to  include  interest  and  penalties  related  to  uncertain  tax  penalties,  if  any,  within  the  provision  for  taxes  in  the  statements  of
operations. During the years ended December 31, 2020 and 2019, the Company incurred no interest and penalties related to income taxes.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our  management,  with  the  participation  of  our  principal  executive  officer  and  principal  financial  officer,  evaluated  the  effectiveness  of  our  disclosure
controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended ("Exchange
Act").  Based  upon  such  evaluation,  our  principal  executive  officer  and  principal  financial  officer  have  concluded  that  the  disclosure  controls  and
procedures were effective as of December 31, 2020 to ensure that information required to be disclosed by the Company in the reports it files or submits
under  the  Exchange  Act  is  recorded,  processed,  summarized  and  reported  within  the  time  period  specified  in  the  U.S.  Securities  and  Exchange
Commission's ("SEC") rules and forms, and to ensure that information required to be disclosed by the Company in the reports 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 disclosure.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-
15(f) and 15d-15(f) under the Exchange Act. Under the supervision and with the participation of our management, including the Chief Executive Officer
and the Chief Financial Officer, we conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting as of December
31, 2020 based on the 2013 framework established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway  Commission  (COSO).  The  Company’s  internal  control  over  financial  reporting  includes  policies  and  procedures  that  provide  reasonable
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  reporting  purposes  in  accordance  with
GAAP.  Based  on  our  evaluation  under  this  framework,  our  management  concluded  that  the  Company’s  internal  control  over  financial  reporting  was
effective as of December 31, 2020.

In addition, we are an "emerging growth company," as defined under the JOBS Act, and are subject to reduced public company reporting requirements. The
JOBS Act provides that an "emerging growth company" is not required to have the effectiveness of the Company's internal control over financial reporting
audited by its external auditor for as long as the Company is deemed to be an "emerging growth company."

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and
15d-15(d) of the Exchange Act that occurred during the three months ended December 31, 2020 that have materially affected, or are reasonably likely to
materially affect, our internal control over financial reporting.
