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  few  years  and  may  not  be  able  to  achieve  or  sustain  revenues  or
profitability in the future.
Although we generate revenue from Gvoke, Keveyis and Recorlev, 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 commercial 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.
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.
Our  reliance  on  third-party  suppliers,  including  single-source  suppliers,  and  a  limited  number  of  options  for  alternate  sources  for  Gvoke,
Keveyis, and Recorlev or our product candidates could harm our ability to develop our product candidates or to commercialize Gvoke, Keveyis,
Recorlev or any product candidates that are approved.
Reimbursement decisions by third-party payors and consolidation within the healthcare industry and among competitors more generally 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 and pricing pressure may impact our ability to sell our products at prices necessary to support our current business strategies.
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.
Gvoke, Keveyis, Recorlev 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.
Our failure to successfully identify, develop and market additional product candidates, or acquire additional product candidates or enter into
collaborations or other commercial agreements could impair our ability to grow.
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.
We  may  not  be  able  to  successfully  integrate  and  combine  the  businesses  of  Xeris  and  Strongbridge  following  the  completion  of  the
Transactions and we may not realize the anticipated benefits from the Transactions.
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  biopharmaceutical  company  committed  to  developing  and  commercializing  innovative  solutions  to  enhance  the  lives  of  people  with  life-
threatening diseases. Our primary focus is on therapies for patient populations in endocrinology, neurology, and gastroenterology. We currently have three
commercially available products, Gvoke, a ready-to-use liquid glucagon for the treatment of severe hypoglycemia, Keveyis, the first and only U.S. Food
and Drug Administration (“FDA”) approved therapy for primary periodic paralysis (“PPP”) and Recorlev, approved by the FDA in December 2021 for the
treatment of endogenous hypercortisolemia in adult patients with Cushing’s Syndrome. We also have a pipeline of development programs to extend our
TM
current marketed products into new indications and uses or bring new products forward using our proprietary formulation technology platforms, XeriSol
and XeriJect

TM
.

Commercial Products

Our number one priority is maximizing the commercial potential of our three commercial products: Gvoke, Keveyis and Recorlev.

• Gvoke (Gvoke HypoPen, Gvoke PFS, Gvoke Kit) is the first ready-to-use liquid stable glucagon for severe hypoglycemia. The product is indicated
for  use  in  pediatric  and  adult  patients  with  diabetes  age  2  years  and  above  and  can  be  administered  in  2  simple  steps.  The  estimated  total
addressable market for this therapy is approximately $4.0 billion in the United States.

Throughout this document, unless otherwise noted, references to Gvoke include Gvoke PFS, Gvoke HypoPen, Gvoke Kit and Ogluo.

•

•

Keveyis is the first and only therapy approved in the United States to treat hyperkalemic, hypokalemic, and related variants of PPP. PPP is a rare
genetic,  neuromuscular  disorder  that  can  cause  extreme  muscle  weakness  and/or  paralysis;  some  forms  are  also  commonly  associated  with
myotonia or muscle stiffness. The estimated total addressable market for this therapy is greater than $0.5 billion in the United States.

Recorlev is a cortisol synthesis inhibitor proved for the treatment of endogenous hypercortisolemia in adult patients with Cushing’s syndrome for
whom  surgery  is  not  an  option  or  has  not  been  curative.  Endogenous  Cushing’s  syndrome  is  a  rare  but  serious  and  potentially  fatal  endocrine
disease caused by chronic elevated cortisol exposure. The estimated total addressable market for this therapy is approximately $2.0 billion in the
United States. Recorlev was approved by FDA on December 30, 2021 and launched in the United States in January 2022.

Our Strategy

Our goal is to build a leading and profitable biopharmaceutical company that innovates products that transform the lives of people with life-threatening
diseases. To achieve our goal, we are pursuing the following strategies:

<

<

<

<

Maximize  the  commercial  potential  of  our  three  commercial  products.  We  have  built  out  a  robust  endocrinology  and  rare  disease-
focused commercial infrastructure – including fully operational patient and provider support teams – primed to bring the benefits of our
products  to  a  wider  range  of  patients  with  unmet  needs.  Our  sales,  marketing,  market  access  and  patient  service  capabilities  in  the
United States are positioned to drive the growth of our products. We believe that our ability to execute on this strategy is enhanced by
the significant commercial experience of key members of our management team.
Create  momentum  through  commercial  execution  leading  to  profitability.  We  have  three  innovative  commercial  assets:  Gvoke,
Keveyis  and  Recorlev.  Gvoke  and  Keveyis  are  growing  in  large  untapped  addressable  markets.  We  are  executing  a  rapid  launch  of
Recorlev, leveraging our experienced, endocrinology-focused commercial infrastructure, in a large and unsatisfied Cushing Syndrome
marketplace.  Through  the  momentum  created  by  the  execution  of  our  three  commercial  products,  we  believe  we  will  have  a  path  to
profitability.
Continue  to  leverage  our  technology  and  expertise  to  develop  a  portfolio  of  product  candidates.  We  have  an  extensive  pipeline  of
development  programs  to  extend  the  current  marketed  products  into  important  new  indications  and  uses,  and  bring  new  products
forward using our formulation technology platforms, supporting long-term product development and commercial success. XeriSol and
XeriJect have broad application and have the potential to be utilized across a range of potential product candidates in endocrinology,
neurology and other therapeutic areas.
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  broaden  our  revenue  stream  and  enhance  the  formulation,  delivery  and  clinical  profile  of  other
companies’  proprietary  drugs  and  biologics.  We  currently  are  working  with  several  major  pharmaceutical  companies  on  feasibility
programs  to  evaluate  the  formulation  of  their  proprietary  therapeutics  with  XeriSol  or  XeriJect.  Our  strategic  goal  is  to  enter  into
broader development and ultimately commercial licensing agreements with these partners upon successful completion of the feasibility
programs.

We  believe  these  four  pillars  of  our  strategy  can  bring  new  products  to  market  and  transform  the  lives  of  patients  with  life-threatening  diseases  and
ultimately drive value for Xeris’ shareholders. Pursuing these strategies provides Xeris with a range of value driving opportunities that are incremental to
the value already realized by the Xeris enterprise.

Business Combination

On May 24, 2021, Xeris Pharmaceuticals, Inc. (“Xeris Pharma”) entered into a definitive agreement with Strongbridge Biopharma plc (“Strongbridge”) to
acquire  Strongbridge  (the  “Transaction”).  Following  consummation  of  the  Transaction  on  October  5,  2021,  Xeris  Biopharma  Holdings,  Inc.  (“Xeris
Biopharma”) became the parent company of both Xeris Pharma and Strongbridge. The common stock of both Xeris Pharma and Strongbridge were de-
registered after completion of the Transaction. On October 6, 2021, Xeris Biopharma’s common stock, par value $0.0001 per share, commenced trading on
the  Nasdaq  Global  Select  Market  (“Nasdaq”)  under  the  ticker  symbol  “XERS.”  Xeris  Pharma  was  determined  to  be  the  accounting  acquirer  in  the
Transaction. For further discussion on the Transaction, refer to “Item 1A. Risk Factors,” and “Note 3 - Business combination” in the Notes to Consolidated
Financial Statements.

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 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.

7

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.

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 pre-
filled  syringe  (Gvoke  PFS),  auto-injector  (Gvoke  HypoPen)  or  soon-to-be  available  single  dose  vial  and  syringe  kit  (Gvoke  Kit).  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 a 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 August 23, 2021, we announced that a supplemental new drug application (sNDA) of Gvoke Kit was approved by the FDA. Gvoke Kit will be sold as a
1 mg/0.2 mL single dose vial and syringe kit. Gvoke Kit contains one (1) single-dose sterile syringe with markings for 0.1 mL (0.5 mg pediatric dose) and
0.2 mL (1 mg adult dose), and one single-dose vial containing 0.2 mL of solution. The Gvoke Kit will be available in March 2022.

On July 19, 2021, we announced that we had entered into an exclusive agreement with Tetris Pharma Limited (“Tetris”) for the commercialization of Ogluo
in  the  European  Economic  Area,  United  Kingdom,  and  Switzerland  (the  “Territory”).  Under  the  terms  of  the  applicable  agreements,  Xeris  will  be
responsible for product supply and Tetris will be responsible for commercialization of Ogluo in the Territory. Subject to the terms and conditions set forth
in  the  agreements,  Xeris  will  receive  consideration  tied  to  the  first  commercial  sale  and  other  time-,  launch-  and  sales-related  milestones  and  collect  a
royalty  on  sales.  We  commercially  launched  Ogluo  in  United  Kingdom  through  our  commercialization  partner,  Tetris,  in  December  2021.  We  plan  to
pursue development and commercialization collaborations for most, if not all, of the non-U.S. markets we seek to enter.

Overview of Hypoglycemia

Diabetes is a widespread condition that affects an estimated 537 million people worldwide with an estimated 22 million drug-treated people in the United
States. Among people with diabetes in the United States, essentially all of the approximately 1.6 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. 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.

8

Hypoglycemia is categorized by level of severity, expressed as mild (Level 1), moderate (Level 2) or severe (Level 3) hypoglycemic events. Definitions,
symptoms and treatment recommendations for hypoglycemia per the Americans with Disabilities Act ("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.

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.
According  to  recent  statistics,  hypoglycemia  demanded  242,000  visits  to  the  emergency  department  in  2018,  and  resulted  in  approximately  $1.8  billion
dollars in direct costs associated with emergency care, inpatient care, and ambulatory care in 2009. Additionally, severe hypoglycemia has been attributed
to 27,000 deaths per year.

The  ADA  Standards  of  Medical  Care  in  Diabetes  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.

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, a nasally administered glucagon powder, in July 2019,
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

9

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 United States at the end of 2021, legacy kits and Baqsimi represented approximately 42% and
38%, respectively, Gvoke represented approximately 20% and Zegalogue represented less than 1%.

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), auto-injector
(Gvoke HypoPen) or single dose vial and syringe kit (Gvoke Kit). Gvoke is 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.
24 to 30 months 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 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 to the existing traditionally available glucagon kits.

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 annual growth rate in incidence of diagnosed and treated
people with diabetes is approximately 4% per year. An additional 96 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 1.6 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 7.0 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 United States potential market opportunity may
be up to $4.0 billion.

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. In the United States, approximately 693,000 total

10

 
prescriptions for emergency glucagon were written in 2021, or an 7% increase from 2020. In 2021, a total of approximately 1 million units of emergency
glucagon products were dispensed in the United States, representing total sales of approximately $281 million.

We  commercially  launched  Ogluo  in  the  United  Kingdom  through  our  commercialization  partner,  Tetris,  in  December  2021.  Considering  the  European
Economic Area, United Kingdom, and Switzerland, we estimate that there are an additional 5 million people with diabetes on insulin. However, annually
there are only approximately 1.2M units of glucagon sold in the retail setting, which we believe indicates that the market for emergency glucagon products
is significantly underpenetrated in the Territory.

Commercial Strategy

Our commercial strategy is to increase the number of prescribed and dispensed emergency glucagon products, specifically Gvoke, for people on insulin
therapy. 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,  Gvoke  HypoPen  in  July  2020  and  Gvoke  Kit  in  2022.  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,
previous 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.  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 believe that all patients should have access to potentially lifesaving products such as Gvoke. We have engaged with
payors to more fully understand their drivers and barriers and convey the health and pharmacoeconomic value of Gvoke.
Impact  of  the  ongoing  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. 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 variants in early 2022, our ability to connect with our customers in person became much more limited
and we quickly moved back to more remote interactions. In addition, several conferences and other programs at which we intended to
market  Gvoke  have  been  postponed  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.

Keveyis

Keveyis (dichlorphenamide) is the first and only therapy approved in the United States to treat hyperkalemic, hypokalemic and related variants of PPP, a
group of rare hereditary disorders that cause episodes of muscle weakness or paralysis.

Overview of PPP

PPP is a rare, genetic, neuromuscular disorder related to a defect in muscle ion channels with multiple variants and subtypes. The disease is characterized
by episodes of muscle weakness and paralysis. It often interferes with daily activities and, as patients get older, it can lead to permanent muscle weakness.
PPP may be localized (“focal”) or more widespread (“generalized”), and it often

11

goes underdiagnosed and/or undertreated. Types of periodic paralysis are differentiated by criteria including underlying genetic mutations and changes in
blood  potassium  during  an  episode.  The  two  most  common  forms  of  PPP  are  hypokalemic,  when  episodes  can  be  induced  by  low  blood  levels  of
potassium, and hyperkalemic, when episodes are associated with elevated levels of blood potassium. We believe, based on our market research, that there
are approximately 4,000 to 5,000 patients in the United States diagnosed with PPP.

Keveyis Features and Benefits

Keveyis is an oral carbonic anhydrase inhibitor that was approved by the FDA in the United States in August 2015 to treat hyperkalemic, hypokalemic and
related variants of PPP. The exact mechanism(s) through which oral carbonic anhydrase inhibitors, and Keveyis in particular, decrease the frequency and
severity of periodic paralysis attacks is unknown. However, it is believed that their effects are mediated both locally (i.e., in muscle) and systemically. It is
not known whether their effects are disease-modifying. Keveyis has received orphan drug exclusivity status in the United States through August 7, 2022.

Keveyis has been studied in two separate double-blind, placebo-controlled multi-center studies and proven to be an effective treatment for PPP. Keveyis
was shown to decrease the number of PPP episodes. In addition, episodes that did occur were shorter in duration and not as severe. The most common
adverse reactions with incidence ≥10% and rates greater than placebo in patients treated with Keveyis were paresthesia, cognitive disorder, dysgeusia, and
confusional state. Less than 10% (3/36) of all patients treated with Keveyis in one study withdrew due to an adverse reaction in the double-blind phase;
17% of hyperkalemic patients (2/12) and ~4% (1/24) of hypokalemic patients discontinued treatment.

Keveyis Market Potential

We believe, based on our market research, that there are approximately 4,000 to 5,000 patients in the United States diagnosed with PPP and we believe that
we  can  address  the  market  by  targeting  physicians  who  are  managing  patients  with  PPP,  including  neuromuscular  specialists,  general  neurologists  and
primary care physicians.

Keveyis Commercial Strategy

Our commercial strategy for Keveyis is to promote its unique benefits, as well as a concerted effort to raise awareness about the underlying PPP disease
among the physician/patient/caregiver community with the goal of increasing the rate of diagnosis when the symptoms may otherwise be overlooked. In
addition to a specialty sales force, we established a field-based group of patient access managers and medical affairs liaisons. We use a single, specialty
pharmacy to provide reimbursement, clinical and distribution support for Keveyis and to develop cost-sharing and patient assistance programs to support
qualified, commercially insured patients, federal- and state-insured patients, and uninsured or under-insured patients. We also donate money to independent
charitable foundations dedicated to this cause. Our ultimate goal is to ensure that no PPP patient is denied access to Keveyis for financial reasons. We work
with the patient community to advocate for patients improving diagnosis, genetic testing and treatment.

Recorlev

Recorlev (levoketoconazole), the pure 2S,4R enantiomer of the enantiomeric pair comprising ketoconazole. Recorlev is a next-generation steroidogenesis
inhibitor. The active pharmaceutical ingredient in Recorlev, levoketoconazole, exerts its primary therapeutic effect by blocking the synthesis of cortisol in
the adrenal glands, leading to the reduction and, ideally, the normalization of blood cortisol. Levoketoconazole has been granted orphan drug designation
by the FDA and the EMA for the treatment of endogenous Cushing’s syndrome.

Levoketoconazole inhibits the cortisol synthesis pathway at several points. Based on the results from our SONICS and LOGICS clinical trials, we believe
that  Recorlev  can  have  a  beneficial  impact  on  hypercortisolism,  the  hallmark  of  endogenous  Cushing’s  syndrome,  as  well  as  benefits  related  to  several
comorbidities of endogenous Cushing’s syndrome, including those associated with cardiovascular disease risk, such as diabetes, weight gain and elevation
in LDL-cholesterol.

On December 30, 2021 we announced the FDA approval of Recorlev for the treatment of endogenous hypercortisolemia in adult patients with Cushing’s
syndrome for whom surgery is not an option or has not been curative. Recorlev is not approved for the treatment of fungal infections. The approval of
Recorlev was based upon safety and efficacy data from two positive Phase 3 studies that evaluated a combined study population of 166 patients, which was
representative  of  the  adult  drug-treated  U.S.  population  with  Cushing’s  syndrome.  The  SONICS  study  met  its  primary  and  key  secondary  endpoints,
significantly  reducing  and  normalizing  mean  urinary  free  cortisol  concentrations  without  a  dose  increase.  LOGICS,  a  double-blind,  placebo-controlled
randomized-withdrawal  study  that  met  its  primary  and  key  secondary  endpoints,  confirmed  the  efficacy  and  safety  of  Recorlev  in  normalizing  and
maintaining therapeutic response compared with placebo.

Overview of Endogenous Cushing’s Syndrome

There are two variants of Cushing’s syndrome: exogenous, which is caused by factors outside the body (e.g., corticosteroid or cortisol-like medications)
and endogenous, which is caused by factors within the body. The signs and symptoms may be the same in both forms. The much more common form is
exogenous Cushing’s syndrome, which is often found in people taking cortisol-like medications for long periods of time or for shorter periods of time using
more potent forms. Cortisol-like medications are often used to treat inflammatory disorders such as asthma and rheumatoid arthritis. Unlike endogenous
Cushing’s syndrome, exogenous Cushing’s syndrome may be alleviated by withdrawing the inciting medication.

12

Endogenous  Cushing’s  syndrome  is  a  rare  endocrine  disorder  characterized  by  sustained  elevated  blood  cortisol.  Cortisol  is  a  hormone  produced  in  the
adrenal  gland  and  is  naturally  secreted  as  an  end-product  of  the  activity  of  the  hypothalamic-pituitary-adrenal  axis.  Corticotropin-releasing-hormone
(“CRH”) is secreted from the hypothalamus and stimulates the secretion and release of adrenocorticotropin (“ACTH”) from the pituitary gland, which in
turn  stimulates  cortisol  (and  other  hormone)  secretion  from  the  adrenal  gland.  Cortisol  itself  exerts  negative  feedback  control  on  both  CRH  in  the
hypothalamus and ACTH in the pituitary gland, thereby reducing CRH and ACTH secretion, keeping cortisol levels in a normal range.

The most common form of endogenous Cushing’s syndrome is called Cushing’s disease, which is typically caused by a benign pituitary tumor that secretes
ACTH  autonomously.  Cushing’s  disease  represents  approximately  70%  to  80%  of  patients  with  endogenous  Cushing’s  syndrome.  Other  causes  of
endogenous ACTH-dependent Cushing’s syndrome include extrapituitary tumors producing ACTH, known as ectopic ACTH, or less often CRH (ectopic
CRH).  The  source  of  ectopic  ACTH/CRH  secretion  is  most  often  small-cell  carcinoma  of  the  lung  or  bronchial  carcinoid  tumors,  but  neuroendocrine
tumors found in many different organs can also be sources. In a smaller number of cases, approximately 20%, endogenous Cushing’s syndrome is ACTH-
independent, meaning that it does not arise through tumor secretion of ACTH but rather results from excess autonomous secretion of cortisol itself in the
adrenal gland by adrenocortical tumors, either benign or malignant, or by non-malignant enlargement of the adrenal glands called hyperplasia.

In patients with endogenous Cushing’s syndrome, the normal feedback mechanisms of the hypothalamic-pituitary-adrenal axis are disrupted. This causes
chronic exposure to high circulating cortisol levels that give rise to the clinical state of Cushing’s syndrome. The most common signs and symptoms of the
syndrome include: weight gain, sometimes with unusual fat accumulation in the upper body with a rounded face (“moon face”) and extra fat on the upper
back  and  above  the  collarbones,  along  with  abdominal  fat;  high  blood  sugar  or  diabetes  mellitus;  high  blood  pressure  or  hypertension;  thin  bones  or
osteoporosis; muscle loss or sarcopenia; thin, fragile skin that bruises easily; purple-red stretch marks called striae, usually over the abdomen and under the
arms; depression and difficulty thinking clearly; too much facial hair, or hirsutism, usually noticed only in women; irregular or absent menstrual periods
and infertility; reduced sex drive or libido; and in children, poor height growth.

An estimated 25,000 patients in the United States are diagnosed with endogenous Cushing’s syndrome. When first diagnosed, patients are most commonly
adults aged 20 to 50 and five times more often women than men. However, endogenous Cushing’s syndrome is believed to be underdiagnosed due to lack
of disease recognition, resulting in a delay in diagnosis of six years on average. Endogenous Cushing’s syndrome patients are believed to have a mortality
risk two to three times that of the age-and-gender-matched general population, with cardiovascular disease, including venous thrombosis and infections
being the primary causes of death.

Current Treatment Landscape and Limitations of Current Treatment Options

Treatment of endogenous Cushing’s syndrome varies depending on the cause of the disease. For patients with Cushing’s disease, initial treatment is almost
always the attempted surgical removal of the pituitary tumor. In anticipation of surgery and when surgery is not effective or not an option, drug or radiation
therapy, or both, is used to suppress excessive cortisol production and the accompanying clinical symptoms.

A typical approach to drug therapy is to inhibit cortisol synthesis through the oral administration of an inhibitor of enzymes that regulate adrenal cortisol
synthesis.  Although  approved  in  the  European  Union  for  this  indication,  ketoconazole  is  not  approved  for  this  indication  by  the  FDA  and  is  therefore
prescribed “off-label”. The percentage of endogenous Cushing’s syndrome patients treated with ketoconazole monotherapy who achieve normalized levels
of cortisol, assessed by measuring UFC has been reported from retrospective, uncontrolled studies, with varying definitions of normalization, to be between
33% and 100%.

Metyrapone is another cortisol synthesis inhibitor that blocks cortisol in a different way than ketoconazole or Recorlev. It is not approved for treatment of
Cushing’s syndrome in the US but is used off-label. Metyrapone is approved for use in the United Kingdom and certain other countries as a therapeutic
drug for CS. Elsewhere, including in the US, it is approved as a diagnostic agent in Cushing’s disease. A drug that works through a similar pathway as
metyrapone, called Isturisa (osilodrostat), was granted a marketing authorization in the European Union on January 15, 2020 and in the United States on
March 6, 2020. Etomidate is an intravenously administered sedative that potently inhibits 11β-hydroxylase, like metyrapone and osilodrostat, and is highly
effective to reduce cortisol, but its use is typically limited to the inpatient setting.

An alternative medical approach to treating Cushing’s syndrome targets pituitary tumors that produce ACTH (i.e., in Cushing’s disease). Among Cushing’s
disease patients, the dopamine agonist cabergoline, which is not approved for use to treat Cushing’s disease in the United States, has been shown to achieve
normalization  of  UFC  levels,  gold-standard  evidence  of  disease  control,  in  about  30%  of  patients.  The  SSA  (somatosatin  analog)  pasireotide,  which  is
marketed as Signifor and Signifor LAR for the treatment of Cushing’s disease in the United States, has shown normalization of UFC levels with stable
dosing of the immediate-release formulation in 15% of patients at a dosage of 600 µg twice-daily and in 26% of patients at a dosage of 900 µg twice-daily
over a six-month period. Certain SSAs, including Signifor, are known to have undesirable side effects on glucose metabolism. Forty percent of patients
with Cushing’s disease treated with Signifor in its Phase 3 clinical trial reported the occurrence of hyperglycemia-related adverse events, and in the cohort
receiving Signifor 900 µg twice-daily, glycated hemoglobin (“HbA1c”) increased from 5.8% at baseline to 7.3% at Month 6.

Another alternative drug therapy, Korlym, or mifepristone, works by inhibiting the action of cortisol at the cortisol-receptor level but does not lower blood
cortisol  levels,  which  actually  tend  to  increase  during  therapy.  As  a  result  of  this  mechanism  of  action,  it  is  not  possible  to  monitor  response  (i.e.,
effectiveness and safety) to Korlym by measuring UFC or cortisol levels (from blood or saliva), which are the standard ways clinicians monitor disease
progression and response to treatment. As a result, Korlym is usually titrated

13

and monitored through use of clinical signs and symptoms improvements (e.g., blood sugar reductions). Korlym has been approved in the United States to
control hyperglycemia secondary to hypercortisolism in patients with endogenous Cushing’s syndrome who also have diabetes mellitus. About one-third of
patients with endogenous Cushing syndrome have diabetes. Korlym is contraindicated in pregnant women and in women with a history of unexplained
vaginal  bleeding,  as  its  side  effects  include  termination  of  pregnancy,  endometrial  thickening  and  vaginal  bleeding.  It  is  also  frequently  associated  with
hypokalemia.

Mitotane is an adrenolytic agent (i.e., it destroys the adrenal gland at higher doses) that inhibits steroidogenesis non-selectively at low doses, mainly at
20,22-desmolase (cholesterol side-chain cleavage). It seems to be used primarily in adrenocortical cancer, where it had an FDA indication. There are no
prospective clinical trials describing the use of mitotane in non-malignant endogenous CS, and it is not approved for that use.

We believe that the efficacy and usage limitations and safety concerns associated with other currently available drug therapies for endogenous Cushing’s
syndrome  are  an  important  reason  why  a  significant  unmet  medical  need  exists  among  endogenous  Cushing’s  syndrome  patients  with  persistent  or
recurrent disease post-surgery. In a survey we commissioned in 2019 of 253 U.S. physicians treating patients with Cushing’s syndrome. When asked what
percentage  of  their  endogenous  Cushing’s  patients  currently  receiving  pharmacological  therapy,  they  would  consider  have  symptoms  controlled  vs.
uncontrolled  by  their  medication(s)  for  CS,  the  surveyed  physicians  indicated  that  approximately  39%  of  patients  were  uncontrolled  vs.  61%  were
controlled. We believe that our potential addressable market for Recorlev includes diagnosed endogenous Cushing’s syndrome patients that at any time are
eligible for drug therapy, including patients for whom surgery or radiation is not feasible, is contraindicated or has been unsuccessful.

Recorlev Clinical Trials Program

The  Phase  3  program  for  Recorlev  included  SONICS  and  LOGICS,  two  multinational  studies  designed  to  evaluate  the  safety  and  efficacy  of  Recorlev
when used to treat endogenous Cushing’s syndrome. The SONICS study met its primary and secondary endpoints, significantly reducing and normalizing
mean urinary free cortisol concentrations without a dose increase. The LOGICS study, which met its primary endpoint and key secondary endpoint, was a
double-blind, placebo-controlled randomized-withdrawal study of Recorlev that was designed to supplement the efficacy and safety information provided
by SONICS. The ongoing open-label OPTICS study will gather further useful information related to the long-term use of Recorlev.

The key secondary efficacy endpoint the LOGICS study was the proportion of patients with mUFC normalization, defined as a patient with mUFC at or
below the upper limit of normal reference range (ULN) at the end of randomized withdrawal phase without meeting a requirement for early rescue during
the randomized withdrawal phase. Out of the 79 patients who entered the dose titration and maintenance phase, 37 (47%) patients who met the requirement
to be on a stable therapeutic dose for at least 4 weeks and established normal mUFC at the end of the dose titration and maintenance phase, and 2 patients
who did not meet the requirement due to abnormal mUFC, continued to the randomized-withdrawal phase. Out of 5 patients from the SONICS study who
were enrolled directly in the randomized withdrawal phase, 2 patients had normal mUFC. Among the 39 patients who had normal mUFC at the randomized
withdrawal phase baseline, 21 were randomized to the Recorlev group and 18 to the placebo group. The number and percent of patients who had normal
mUFC at the end of the randomized withdrawal phase was 11/21 (52.4%) in Recorlev group and 1/18 (5.6%) in placebo group, and the treatment difference
(CI) was 46.8% (16.5%, 70.2%). Out of 11 patients with normal mUFC at the end of the randomized-withdrawal phase, 7 patients in the Recorlev group
had normal mUFC throughout the randomized-withdrawal phase.

The primary efficacy endpoint of the SONICS study was the proportion of patients with normalization of mUFC at the end of the 6-month maintenance
phase. Normalization of mUFC was defined as mUFC at or below the ULN based on central laboratory result without requiring a dose increase during the
maintenance  phase.  At  the  end  of  the  maintenance  phase,  29  of  94  patients  (30.9%,  95%  exact  confidence  interval  21.7%,  41.2%)  met  the  primary
endpoint.

The most common adverse reactions (incidence > 20%) for LOGICS and SONICS were nausea/vomiting, hypokalemia, hemorrhage/contusion, systemic
hypertension,  headache,  hepatic  injury,  abnormal  uterine  bleeding,  erythema,  fatigue,  abdominal  pain/dyspepsia,  arthritis,  upper  respiratory  infection,
myalgia, arrhythmia, back pain, insomnia/sleep disturbances, and peripheral edema.

Elevations in AST or ALT post baseline were reported in patients treated with Recorlev who had AST or ALT ≤ ULN at baseline in LOGICS and SONICS.
There were 11 out of 166 patients who had an AST or ALT above the ULN to ˂3 x ULN at baseline. Of these patients, 3 had increases above 3 x ULN, and
none had increases above 5 x ULN. Liver test abnormalities improved with cessation of medication.

In the LOGICS and SONICS studies combined, there were 4 (2.4%) patients who experienced QTcF>500 msec, and 23 (14.7%) patients who experienced
change-from-baseline QTcF >60 msec, respectively. Adverse reactions reported around the same time that may have been associated with QT prolongation
included fatigue, hypertension, nausea/vomiting, and ventricular extrasystoles.

The  FDA-approved  labeling  for  Recorlev  includes  a  boxed  warning  for  hepatotoxicity  and  QT  prolongation  Recorlev  has  been  associated  with  serious
hepatotoxicity and dose-related QT interval prolongation.

OPTICS Phase 3 Clinical Trial

In 2018, we initiated a long-term, open-label extension trial with Recorlev (“OPTICS”) to capture longer-term safety, tolerability and efficacy data from
patients who complete either SONICS or LOGICS and who chose to continue therapy with Recorlev. OPTICS will continue to accrue data on each enrolled
patient for a minimum of three years or until Recorlev has become available in their own country, whichever comes first.

Market Potential

On  December  30,  2021,  the  FDA  approved  Recorlev  for  the  treatment  of  endogenous  hypercortisolemia  in  adult  patients  with  Cushing’s  Syndrome  for
whom surgery is not an option or has not been curative and Recorlev became commercially available in January 2022. We believe approximately 8,000
Cushing’s patients are managed pharmacologically in the U.S. with a tremendous amount of unmet need since nearly 40% of patients are poorly controlled
on their current medication. We believe that this values the Cushing’s market in the U.S. at approximately $2 billion annually. Cushing’s Syndrome is a
complex disease, and we believe that patients could significantly benefit from additional support services and educational resources in conjunction with
therapy.  For  this  reason,  we  have  partnered  with  a  specialty  pharmacy  to  provide  a  customized  support  and  product  distribution  program,  Xeris
CareConnection™,  for  members  of  the  Recorlev  ecosystem,  including  appropriate  patients,  caregivers,  physicians,  and  payors.  Xeris  CareConnection
provides support services throughout the entire treatment journey to patients and healthcare professionals with direct access to pharmacists, reimbursement
specialists  and  access  managers.  The  comprehensive  patient  support  program  includes  welcome  information,  therapy  onboarding,  at-home  delivery  of
medication, a discreet courier service for urinary free cortisol (UFC) test collection, automatic monthly refill shipments, financial assistance programs, one-
on-one support, and ongoing educational resources.

Our Product Candidates

Ready-to-Use Glucagon (XP-9164) for Gastroenterology

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

XP-9164  is  intended  to  address  unmet  needs  in  the  growing  procedural  gastroenterology  market. Glucagon  transiently  decreases  peristalsis  of  smooth
muscle in the gastrointestinal tract. Glucagon administration during gastrointestinal imaging permits more precise visualization for studies and procedures.
It  is  also  used  in  abdominal  vascular  procedures  such  as  treating  esophageal  varices  and  other  GI  bleeds.  Glucagon  is  also  utilized  in  biopsies,  abscess
drainage,  GI  stenting,  gastrostomy  tube  placement  and  colonoscopies.  In  2019  there  were  ~17M  colonoscopies  performed  in  the  U.S.  A  ready-to-use
glucagon  may  potentially  address  a  number  of  areas  of  needed  improvement:  improved  operational  efficiency,  no  reconstitution  (and  thus  fewer
reconstitution errors), room temperature stable liquid, faster preparation and possibly less waste.

Ready-to-Use Glucagon for Exercise-Induced Hypoglycemia(EIH) in Diabetes

Exercise-induced (or exercise-associated) 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.

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 that 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.

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.

15

The study concluded that mini-dose glucagon (150 µg) was 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 resulted in less post-intervention hyperglycemia than ingestion of carbohydrates and avoided the consumption of unnecessary calories. The
results of this study were published in 2018 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. In
January 2020, we reported that a mini-dose of RTU glucagon was adequate to maintain normal blood glucose levels during prolonged, moderate-to-high
intensity aerobic exercise in the CRC setting.

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. In June 2020, we
reported positive results from the outpatient stage of this Phase 2 study. 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.

Based on FDA interactions and expectations for a registrational program to support a mini-dose indication for Glucagon RTU in EIH, we submitted an IND
in February 2022. We received FDA clearance in March 2022 and are actively planning to initiate a new phase 2 clinical program by the end of 2022 to
further address the management of EIH in people with diabetes who use insulin.

Non-Glucagon Programs

Ready-to-Use Product for Endocrinology (Levothyroxine; XP-8121)

We are currently in Phase 1 development with product candidate XP-8121, an early-stage program designed to address maintenance therapy in patients
with congenital or acquired hypothyroidism who require thyroid hormone replacement.

Levothyroxine and Hypothyroidism

The thyroid gland is responsible for the synthesis, storage, and release of metabolic hormones including thyroxine (T4) and triiodothyronine (T3). These
hormones  are  crucial  in  the  regulation  of  critical  metabolic  processes  and  are  vital  for  normal  growth  and  development  during  fetal  life,  infancy,  and
childhood.

Therapeutically, levothyroxine is administered when the body is deficient in the endogenous hormone. The goal of therapy is restoration of the euthyroid
state which can reverse the clinical manifestations of hypothyroidism and significantly improve quality of life. The treatment of choice for correction of
hypothyroidism is levothyroxine, which is the mainstay of thyroid hormone replacement therapy. It is one of the most widely prescribed drug products in
the United States, but the complexity of maintaining biochemical and clinical euthyroidism in patients undergoing treatment with oral levothyroxine cannot
be underestimated. It has been reported that nearly 40% of patients undergoing treatment with oral levothyroxine are either over- or under-treated due to
factors that include, but are not limited to, drug formulation, use of the drug with food, adherence to the drug, use of concomitant medications, and pre-
existing medical conditions. Many patients failing to reach target TSH levels are generally managed by simply increasing their levothyroxine daily dose.
However, levothyroxine is a drug with a narrow therapeutic index, meaning that relatively small deviations from the proper dose can cause a clinically
meaningful shift in pharmacological effects when administered to a patient; thus, the titration of levothyroxine oral drug may be a tailored and incremental
process.

XP-8121 Overview

XP-8121 is a novel formulation for subcutaneous administration that could potentially mitigate many of the challenges associated with oral formulations,
such as identification of an ideal dose due to absorption variation and medication adherence for patients who have

16

difficulty maintaining a stable, therapeutic serum level. Preclinical studies of SC XP-8121 showed a sustained plasma exposure profile and similar Cmax
when compared with equivalent doses of the oral formulation. We are currently conducting a Phase 1 study of XP-8121 to evaluate the pharmacokinetics,
safety and tolerability, and potential for weekly dosing in the treatment of hypothyroidism.

The  Phase  1  clinical  study  is  a  single  ascending  dose  crossover  design  in  30  healthy  participants  to  compare  matching  doses  of  oral  levothyroxine
(Synthroid®) and subcutaneous XP-8121. The primary endpoints of the study are to characterize the absorption and elimination kinetics of XP-8121 and
compare bioavailability of XP-8121 to oral levothyroxine. Secondary endpoints are safety and tolerability of XP-8121.

Market Opportunity

There are more than 100 million prescriptions written for oral levothyroxine per year, making it one of the most prescribed therapies in the United States.
Non-adherence  to  daily  therapy,  resistant  hypothyroidism,  and  limited  GI  absorption  are  some  of  the  major  reasons  for  treatment  failure  or  suboptimal
treatment with oral levothyroxine. We believe these challenges could be mitigated by XP-8121, if approved, and translate into the long-term health benefit
of achieving a euthyroid state for patients. It is estimated that 47% of patients have an associated GI condition o 15% experience inadequate control of
symptoms. Assuming 56 million weekly doses per year and $30 per dose comparable to branded orals, this represents a $1 to $2 billion market opportunity.

XeriSol Pramlintide-Insulin Co-formulation (XP-3924)

Xeris Pharma has developed a novel, investigational fixed-ratio co-formulation of pramlintide and regular human insulin (XP-3924) to improve glycemic
control in adult and pediatric patients with diabetes mellitus (T1D and T2D). Xeris’ proprietary formulation technology (XeriSol™) enables the 2 peptides
(pramlintide and insulin), which require different aqueous pH environments for optimal stability, to be co-formulated in a stable ready-to-use solution. The
current formulation patent exists through at least Q4 2032, expected to extend to 2036 with successful prosecution of the currently pending continuation
application, and through 2041-2042 with the ongoing formulation development work

XP-3924 Market Opportunity

We believe XP-3924 has the opportunity to serve a large unmet need in patients on mealtime insulin, with the market opportunity estimated at $3-4 billion
in the United States. It is estimated that ~1/3 of patients on mealtime insulin are not achieving their A1C goals despite optimized insulin therapy. Additional
therapeutic options for patients with advanced diabetes not well-controlled on mealtime insulin are limited. The only pharmacological therapy indicated for
such patients is pramlintide (Symlin®). We have an open IND for XP-3924, recently completed a Phase 2 clinical trial in adults with Type 1 Diabetes and
obtained  FDA  feedback  on  the  clinical  development  and  regulatory  requirements  for  submitting  a  351(a)  stand-alone  BLA.  We  are  currently  seeking
partners to license the development and commercialization rights to XP-3924 in the US.

Ready-to-Use Diazepam (XP-0863)

XP-0863  is  a  liquid  formulation  of  diazepam  for  intramuscular  injection  being  studied  for  the  treatment  of  ARS.  Xeris’  patent  protected  technology
XeriSol™ has been used to develop a room-temperature stable, ready-to-use, small-volume solution of diazepam for intramuscular injection delivered by
an auto-injector, which will provide patients and caregivers an alternative to rectal and nasal administrations of benzodiazepines. XP-0863 is designed to
address variable absorption, and suboptimal PK profiles of the currently marketed formulations of benzodiazepines, by offering a longer duration of action,
consistent absorption of drug delivered through intramuscular administration, and a convenient and reliable form factor of the autoinjector. XP-0863 has
been 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.

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.  We  believe  that,  if
approved, XP-0863 would have the opportunity to fill the unmet need in ARS for a reliable, user-friendly treatment option with adequate onset of action
and durable effect sufficient to break the seizure cluster and prevent recurrence. The market opportunity is estimated at ~$650-1.3B.

We have completed a Phase 1a and a Phase 1b single dose studies in healthy subjects vs. Diastat® which demonstrated Cmax comparable to and Tmax
longer  than  Diastat®,  comparable  partial  AUCs  across  early  timepoints,  increased  overall  exposure  (AUC0-∞)  when  compared  to  Diastat®,  and  dose
proportionality. XP-0863 was safe and well-tolerated with minimal sedation, minimal injection site reactions and no serious adverse events. In addition to
the orphan designation, the FDA has granted Fast Track designation and aligned on the proposed clinical development plan of a single Phase 3, single arm
safety study in patients with epilepsy as well as a 505(b)(2) submission. A primary container and device partner has been identified to develop a pre-filled
syringe

17

and/or rescue autoinjector. We are currently seeking partners to license the development and commercialization rights to XP-0863 in the US.

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  the  FDA’s  current  Good  Manufacturing  Practice  requirements  ("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 glucagon API requirements for Gvoke and other ready-to-use glucagon product candidates, 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  as  its  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 have a supply agreement with Taro Pharmaceuticals U.S.A., Inc. ("Taro") to produce Keveyis. The supply agreement may extend beyond the orphan
exclusivity period unless terminated by either party pursuant to the terms of the agreement. If the supply agreement is terminated by Taro at the conclusion
of the orphan exclusivity period, we have the right to manufacture the product on our own or have the product manufactured by a third party on our behalf.

Levoketoconazole is the API used in Recorlev. Regis Technologies, Inc. ("Regis”) has been actively involved in the development of levoketoconazole and
its  facility  in  Illinois  is  our  sole  source  for  API.  We  have  entered  into  a  supply  agreement  with  Regis.  We  believe  that  Regis  has  sufficient  capacity  to
satisfy our demand requirements for at least three to five years.

Manufacturing Recorlev drug product requires a conventional solid oral dosage form manufacturing facility. Xcelience, LLC. (“Lonza”) has been actively
involved  in  the  development  of  Recorlev  and  its  facility  in  Florida  is  our  sole  source  for  drug  product.  We  have  entered  into  a  supply  agreement  with
Lonza. We believe that Lonza has sufficient capacity to satisfy our demand requirements for at least three to five years.

We  believe  that  a  number  of  CMOs  can  provide  suitable  secondary  packaging  services  for  Gvoke  and  Recorlev,  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.  specialty  pharmacies  and  wholesale  customers,  and  we  have  a  commercial  distribution  agreement  with  one  such  vendor  for  Gvoke,
Keveyis and Recorlev.

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. While we believe that our employees, 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.

Gvoke: 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. 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. We believe that the drawbacks of
traditional kits and the lack of conversations regarding glucagon limit their adoption. Three innovative glucagon products are currently
available  to  treat  severe  hypoglycemia,  including  our  Gvoke,  Eli  Lilly's  intranasal  glucagon  dry  powder,  Baqsimi,  and  Zealand
Pharma’s dasiglucagon auto-injector, Zegalogue.

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.

Keveyis: Keveyis is  the  first  and  only  FDA  approved  therapy  for  PPP.  Acetazolamide,  an  oral  carbonic  anhydrase  inhibitor,  is  used
frequently  off-label  for  the  prophylactic  and  sometimes  acute  treatment  of  PPP.  Potassium  supplements  are  indicated  for  use  in
hypokalemic periodic paralysis in the United States and are frequently used either chronically or for emergency treatment of episodes in
the form of PPP. Several other types of drugs have been reported to have benefits for chronic or acute use in one or more than one PPP
variant, including potassium-sparing diuretics, beta receptor agonists, mexelitine and other sodium channel blockers, and others. We are
not aware of drugs currently in development for prophylactic chronic treatment of PPP.
Recorlev: A  number  of  therapies  are  currently  approved  or  in  various  stages  of  development  for  endogenous  Cushing’s  syndrome.
Currently, there are no therapies broadly marketed for the treatment of endogenous Cushing’s syndrome patients in the U.S. Korlym
(mifepristone)  is  indicated  to  control  hyperglycemia  secondary  to  hypercortisolism  in  adult  patients  with  endogenous  Cushing’s
syndrome who have type 2 diabetes mellitus or glucose intolerance and have failed surgery or are not candidates for surgery. Signifor
(pasireotide) and Signifor LAR are marketed by Recordati in the United States and are indicated for the treatment of adult patients with
Cushing's  disease  (a  subset  of  Cushing’s  syndrome)  for  whom  pituitary  surgery  is  not  an  option  or  has  not  been  curative.  Isturisa
(osilodrostat) is a cortisol synthesis inhibitor indicated for adult patients with Cushing’s disease (a subset of Cushing’s syndrome) for
whom  pituitary  surgery  is  not  an  option  or  has  not  been  curative  is  marketed  by  Recordati.  A  number  of  products,  including
ketoconazole, metyrapone, cabergoline, mitotane and etomidate are used off-label for the treatment of Cushing’s Syndrome in the U.S.
Ketoconazole, metyrapone and mitotane are marketed by HRA Pharma in certain European countries. Products in development include
relacorilant  (CORT125134),  a  selective  glucocorticoid  receptor  antagonist,  currently  in  Phase  3  for  Cushing’s  syndrome  by  Corcept
Therapeutics. AstraZeneca PLC. is developing AZD-4017 inhibitor of 11 beta-hydroxysteroid dehydrogenase 1 (11BHSD1), currently
in  Phase  2.  Sparrow  Pharmaceuticals  is  developing  SPI-62,  a  HSD-1  inhibitor,  currently  in  Phase  2.  Synchronicity  Pharma  Inc.  is
developing  SHP-1705,  which  acts  by  modulating  cryptochrome  (Cry)  receptor  activity,  currently  in  Phase  1.  Sosei  Heptares  is
developing  HTL-0030310  a  selective  somatostatin  receptor  5  agonist,  currently  in  Phase  1.  Crinetics  has  initiated  a  double-blind,
randomized,  placebo-controlled  Phase  1  study  of  this  orally  administered,  nonpeptide  small  molecule  drug  candidate  in  healthy
volunteers. This study will assess the safety and tolerability of single and multiple doses of CRN04894 and will measure the effect of
CRN04894 on suppression of cortisol, cortisol precursors, and adrenal androgens following exogenous ACTH stimulation.

Regulation

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.

Certain  of  our  products  and  product  candidates  are  subject  to  regulation  as  combination  products,  which  means  that  they  are  composed  of  both  a  drug
product and device product. If our drug products, along with our combination product, 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 ("CDER")
or FDA’s Center for Biologics Evaluation and Research ("CBER") has primary jurisdiction over the premarket development, review and approval of the
combination product. 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 component of our combination products, 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:

20

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 FDA's Clinical Practices ("GCPs") regulations, 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 CGMP regulations;
potential FDA inspection of Xeris, the clinical trial sites, or other vendors 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 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

21

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.  In  addition,  for  certain  combination  products  it  may  be  necessary  to  conduct  Human  Factors  studies  prior  to  NDA  or  BLA  submission  to
ascertain the usability of the product by patients in real-world settings.

FDA Review Process

The  results  of  product  development,  preclinical  studies,  Human  Factors  studies  (when  required),  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, most NDAs or BLAs must be accompanied by a significant application user fee to the FDA. There also are continuing user fee requirements,
under  which  the  FDA  assesses  an  annual  program  fee  for  each  product  identified  in  an  approved  NDA  or  BLA.  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 which we utilized for Gvoke.

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  may  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

22

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  at  least  two  adequate  and  well-controlled  clinical  studies  and  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 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 alternative 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

23

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 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.

24

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 
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;
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

25

 
 
 
 
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  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 or 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,

26

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 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

27

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 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 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,  pricing,
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. Similar requirements are necessary to conduct clinical trials in the United Kingdom, with the submission of an MAA to the CHMP for marketing
authorization.

Clinical Trial Approval

In April 2014, the EU adopted the new Clinical Trials Regulation (EU) No 536/2014 (CTR), which replaced the Clinical Trials Directive. The CTR entered
into  application  on  January  31,  2022.  The  transitory  provisions  of  the  CTR  offer  sponsors  the  possibility  to  choose  between  the  requirements  of  the
previous Clinical Trials Directive and the CTR if the request for authorization of a clinical trial is submitted in the year after the CTR became applicable. If
the sponsor chooses to submit under the Clinical Trials Directive, the clinical trial continues to be governed by the Clinical Trial Directive until three years
after the CTR became applicable. If a clinical trial continues for more than three years after the CTR became applicable, the CTR will at that time begin to
apply to the clinical trial. The CTR overhauls the current system of approvals for clinical trials in the EU. Specifically, the new legislation, which is directly
applicable in all EU Member States (meaning no national implementing legislation in each Member State is required), aims at simplifying and streamlining
the approval of clinical trials in the EU, simplifying adverse-event reporting procedures, improving the supervision of clinical trials and increasing their
transparency.  For  instance,  the  CTR  provides  for  a  streamlined  application  procedure  via  a  single-entry  point  and  strictly  defined  deadlines  for  the
assessment of clinical trial applications. Parties conducting certain clinical trials must, as in the United States, post clinical trial information in the EU at the
EudraCT website: https://eudract.ema.europa.eu.

Marketing Authorization

To obtain a marketing authorization for a product under EU regulatory systems, an applicant must submit an MAA either under a centralized procedure
administered  by  the  EMA,  or  one  of  the  procedures  administered  by  competent  authorities  in  the  EU  Member  States  (decentralized  procedure,  national
procedure  or  mutual  recognition  procedure).  The  centralized  procedure  provides  for  the  grant  of  a  single  marketing  authorization  by  the  European
Commission that is valid throughout the EU, and in the additional Member States of the European Economic Area (Iceland, Liechtenstein and Norway).
Pursuant  to  Regulation  (EC)  No  726/2004,  the  centralized  procedure  is  compulsory  for  specific  products,  including  for  medicines  produced  by  certain
biotechnological processes, products designated as orphan medicinal products, advanced therapy medicinal products (gene-therapy, somatic cell-therapy or
tissue-engineered  medicines),  and  products  with  a  new  active  substance  indicated  for  the  treatment  of  HIV,  AIDS,  cancer,  neurodegenerative  disorders,
diabetes,  auto-immune  and  other  immune  dysfunctions,  and  viral  diseases.  The  centralized  procedure  is  optional  for  products  containing  a  new  active
substance not yet authorized in the EU, or for products that constitute a significant therapeutic, scientific or technical innovation or which are in the interest
of public health in the EU.

Under  the  centralized  procedure,  the  CHMP  is  responsible  for  conducting  the  initial  assessment  of  a  product  and  for  several  post-authorization  and
maintenance activities, such as the assessment of modifications or extensions to an existing marketing authorization. Under the centralized procedure in the
EU, the maximum timeframe for the evaluation of an MAA by the EMA is 210 days, excluding clock stops, when additional written or oral information is
to be provided by the applicant in response to questions asked by the CHMP. Clock stops may extend the timeframe of evaluation of an MAA considerably
beyond 210 days. Where the CHMP gives a positive opinion, it provides the opinion together with supporting documentation to the European Commission,
who  makes  the  final  decision  to  grant  a  marketing  authorization,  which  is  issued  within  67  days  of  receipt  of  the  EMA’s  recommendation.  Accelerated
evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is expected to be of major interest from the point of view of
public health and in particular from the viewpoint of therapeutic innovation. If the CHMP accepts such request, the time limit of 210 days will be reduced
to 150 days, excluding clock stops, but it is possible that the CHMP can revert to the standard time limit for the centralized procedure if it considers that it
is no longer appropriate to conduct an accelerated assessment.

National marketing authorizations, which are issued by the competent authorities of the Member States of the EU and only cover their respective territory,
are available for products not falling within the mandatory scope of the centralized procedure. Where a product has already been authorized for marketing
in a Member State of the EU, this national authorization can be recognized in other Member States through the mutual recognition procedure. If the product
has  not  received  a  national  authorization  in  any  Member  State  at  the  time  of  application,  it  can  be  approved  simultaneously  in  various  Member  States
through the decentralized procedure.

Now that the UK (which comprises Great Britain and Northern Ireland) has left the EU, Great Britain will no longer be covered by centralized marketing
authorizations (under the Northern Ireland Protocol, centralized marketing authorizations will continue to be recognized in Northern Ireland). All medicinal
products with a current centralized marketing authorization were automatically converted to Great Britain marketing authorizations on January 1, 2021. For
a period of two years from January 1, 2021, the Medicines and Healthcare Products Regulatory Agency (MHRA), the UK medicines regulator, may rely on
a decision taken by the European Commission on the approval of a new marketing authorization in the centralized procedure, in order to more quickly
grant a new Great Britain marketing authorization. A separate application will, however, still be required. The MHRA also has the power to have regard to
marketing authorizations approved in EU Member States through decentralized or mutual recognition procedures with a view to more quickly granting a
marketing authorization in the UK or Great Britain.

Data and Market Exclusivity

In the EU, innovative medicinal products approved on the basis of a complete independent data package qualify for eight years of data exclusivity upon
marketing authorization and an additional two years of market exclusivity. Data exclusivity, if granted, prevents applicants for authorization of generics or
biosimilars of these innovative products from referencing the innovator’s pre-clinical and clinical trial data contained in the dossier of the reference product
when applying for a generic or biosimilar marketing authorization in the EU, during a period of eight years from the date on which the reference product
was first authorized in the EU. During an additional two-year period of market exclusivity, a generic or biosimilar MAA can be submitted and authorized,
and  the  innovator’s  data  may  be  referenced,  but  no  generic  or  biosimilar  medicinal  product  can  be  placed  on  the  EU  market  until  the  expiration  of  the
market exclusivity. The overall ten-year period will be extended to a maximum of 11 years if, during the first eight years of those ten years, the marketing
authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization,
are held to bring a significant clinical benefit in comparison with existing therapies. There is no guarantee that a product will be considered by the EMA to
be  an  innovative  medicinal  product,  and  products  may  not  qualify  for  data  exclusivity.  Even  if  a  product  is  considered  to  be  an  innovative  medicinal
product so that the innovator gains the prescribed period of data exclusivity, another company nevertheless could also market another version of the product
if such company obtained marketing authorization based on an MAA with a complete independent data package of pharmaceutical tests, preclinical tests
and clinical trials.

Orphan Designation and Exclusivity

In the EU, the EMA’s Committee for Orphan Medicinal Products ("COMP") grants orphan designation to promote the development of products that: (1) are
intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition: (2) either (a) such condition affects no more
than five in 10,000 persons in the EU when the application is made, or (b) it is unlikely that the product, without the benefits derived from orphan status,
would generate sufficient return in the EU to justify the necessary

29

investment in its development; and (3) there exists no satisfactory method of diagnosis, prevention, or treatment of such condition has been authorized for
marketing in the EU or, if such method exists, the product would be of a significant benefit to those affected by that condition. The application for orphan
designation must be submitted before the application for marketing authorization.

In the EU, orphan 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. During the ten-year market exclusivity period, the EMA cannot accept an MAA, or grant a marketing authorization,
or accept an application to extend a marketing authorization, for the same therapeutic indication, in respect of a “similar medicinal product”. A “ similar
medicinal product” is defined as a medicinal product containing a similar active substance or substances as contained in an authorized orphan medicinal
product, and which is intended for the same therapeutic indication. 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 medicinal product that is shown to be safer, more effective or otherwise clinically superior.

Regulation of Combination Products

The EU regulates medical devices and medicinal products separately, through different legislative instruments, and the applicable requirements will vary
depending on the type of drug-device combination product. EU guidance has been published to help manufacturers select the right regulatory framework.
In the case of drug-delivery products intended to administer a medicinal product where the device and the medicinal product do not form a single integral
product, the medicinal product is regulated in accordance with the aforementioned rules while the device part is regulated as a medical device and will have
to  comply  with  all  the  requirements  set  by  Regulation  2017/745,  or  the  Medical  Devices  Regulation  (which  became  applicable  on  26  May  2021  and
repealed  the  EU  Council  Directive  93/42/EEC,  or  the  Medical  Devices  Directive).  Where  the  medical  device  and  medicinal  product  form  a  single
integrated product (e.g. pre-filled inhalers), if the principal intended action is achieved by the medicine, the product is considered a medicinal product that
includes a medical device and the entire product is regulated under the EU pharmaceutical legislation. However, the MAA for the product should include a
CE certificate for the device in accordance with the Medical Devices Regulation or, if not CE marked but would need to be certified if marketed separately,
the  applicant  must  include  an  opinion  from  a  notified  body  on  conformity  of  device  (except  for  Class  I  devices).  This  is  a  requirement  under  the  new
Medical Devices Regulation.

The  characteristics  of  non-integral  devices  used  for  the  administration  of  medicinal  products  may  impact  the  quality,  safety  and  efficacy  profile  of  the
medicinal  products.  To  the  extent  that  administration  devices  are  co-packaged  with  the  medicinal  product  or,  in  exceptional  cases,  where  the  use  of  a
specific type of administration device is specifically provided for in the product information of the medicinal product, additional information may need to
be provided in the MA application for the medicinal product on the characteristics of the medical device(s) that may impact on the quality, safety and/or
efficacy of the medicinal product. The requirements regarding quality aspects for integral drug-device combination products, including devices that are co-
packaged with medicinal products, are outlined in an EMA guideline which came into effect on January 1, 2022.

The EU requires that all medical devices placed on the market in the EU must meet the relevant general safety and performance requirements laid down in
Annex I of the Medical Devices Regulation. The most fundamental requirement is that a medical device must be designed and manufactured in such a way
that it will not compromise the clinical condition or safety of patients, or the safety and health of users and others. In addition, the device must achieve the
performances  intended  by  the  manufacturer  and  be  designed,  manufactured,  and  packaged  in  a  suitable  manner.  To  demonstrate  compliance  with  the
general  safety  and  performance  requirements  laid  down  in  Annex  I  to  the  Medical  Devices  Regulation,  medical  device  manufacturers  must  undergo  a
conformity  assessment  procedure,  which  varies  according  to  the  type  of  medical  device  and  its  (risk)  classification.  Conformity  assessment  procedures
require  an  assessment  of  available  clinical  evidence,  literature  data  for  the  product,  and  post-market  experience  in  respect  of  similar  products  already
marketed. Except for low-risk medical devices (Class I non-sterile, non-measuring devices), where the manufacturer can self-declare the conformity of its
products  with  the  general  safety  and  performance  requirements  (except  for  any  parts  which  relate  to  sterility  or  metrology),  a  conformity  assessment
procedure requires the intervention of a Notified Body. Notified Bodies are independent organizations designated by EU countries to assess the conformity
of devices before being placed on the market. If satisfied that the relevant product conforms to the relevant general safety and performance requirements,
the Notified Body issues a certificate of conformity, which the manufacturer uses as a basis for its own declaration of conformity. The manufacturer may
then apply the CE Mark to the device, which allows the device to be placed on the market throughout the EU.

As a general rule, demonstration of conformity of medical devices and their manufacturers with the general safety and performance requirements must be
based,  among  other  things,  on  the  evaluation  of  clinical  data  supporting  the  safety  and  performance  of  the  products  during  normal  conditions  of  use.
Specifically,  a  manufacturer  must  demonstrate  that  the  device  achieves  its  intended  performance  during  normal  conditions  of  use,  that  the  known  and
foreseeable risks, and any adverse events, are minimized and acceptable when weighed against the benefits of its intended performance, and that any claims
made about the performance and safety of the device are supported by suitable evidence.

The aforementioned EU rules are generally applicable in the European Economic Area, or EEA, which consists of the EU Member States, plus Norway,
Liechtenstein and Iceland.

Brexit and the Regulatory Framework in the United Kingdom

On June 23, 2016, the electorate in the UK voted in favor of leaving the EU, commonly referred to as Brexit, and the UK formally left the EU on January
31, 2020. There was a transition period during which EU pharmaceutical laws continued to apply to the UK, which

30

expired  on  December  31,  2020.  However,  the  EU  and  the  UK  have  concluded  a  trade  and  cooperation  agreement,  or  TCA,  which  was  provisionally
applicable since January 1, 2021 and has been formally applicable since May 1, 2021. The TCA includes specific provisions concerning pharmaceuticals,
which  include  the  mutual  recognition  of  GMP,  inspections  of  manufacturing  facilities  for  medicinal  products  and  GMP  documents  issued,  but  does  not
foresee  wholesale  mutual  recognition  of  UK  and  EU  pharmaceutical  regulations.  At  present,  Great  Britain  has  implemented  EU  legislation  on  the
marketing, promotion and sale of medicinal products through the Human Medicines Regulations 2012 (as amended) (under the Northern Ireland Protocol,
the EU regulatory framework will continue to apply in Northern Ireland). The regulatory regime in Great Britain therefore largely aligns with current EU
regulations, however it is possible that these regimes will diverge in future now that Great Britain’s regulatory system is independent from the EU and the
TCA does not provide for mutual recognition of UK and EU pharmaceutical legislation.

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 the federal government and the states in which we conduct our business as well as in foreign jurisdictions in which we may
conduct trials or where we may otherwise be subject to local regulation. The laws that may affect our ability to operate include:

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 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 program;
The federal civil and criminal false claims and civil monetary penalties laws, including the federal False Claims Act ("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;
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;

the federal Health Insurance Portability and Accountability Act of 1996 ("HIPAA"), as amended by the Health Information Technology
for Economic and Clinical Health Act of 2009 ("HITECH") and their respective implementing regulations, including the Final Omnibus
Rule  published  in  January  2013,  which  impose  requirements  on  certain  covered  healthcare  providers,  health  plans,  and  healthcare
clearinghouses  as  well  as  their  respective  business  associates,  independent  contractors  or  agents  of  covered  entities,  that  perform
services  for  them  that  involve  the  creation,  maintenance,  receipt,  use,  or  disclosure  of,  individually  identifiable  health  information
relating to 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. In addition, there may be additional federal, state and non-
U.S. laws which govern the privacy and security of health and other personal information in certain circumstances, many of which differ
from each other in significant ways and may not have the same effect, thus complicating compliance efforts. In addition, HIPAA, which
created new federal criminal statutes that prohibit a person from 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,  fictitious,  or  fraudulent  statements  or  representations  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.
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  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 non-physician providers such as physician assistants and
nurse practitioners.
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

32

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.

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.

In the U.S., to help patients afford our approved product, we may utilize programs to assist them, including patient assistance programs (PAPs) and co-pay
coupon  programs  for  eligible  patients.  PAPs  are  regulated  by  and  subject  to  guidance  from  CMS  OIG.  In  addition,  at  least  one  insurer  has  directed  its
network pharmacies to no longer accept co-pay coupons for certain specialty drugs the insurer identified. Our co-pay coupon programs could become the
target of similar insurer actions. In addition, in November 2013, the CMS issued guidance to the issuers of qualified health plans sold through the ACA’s
marketplaces encouraging such plans to reject patient cost-sharing support from third parties and indicating that the CMS intends to monitor the provision
of such support and may take regulatory action to limit it in the future. The CMS subsequently issued a rule requiring individual market qualified health
plans to accept third-party premium and cost-sharing payments from certain government-related entities. In September 2014, the OIG of the HHS issued a
Special  Advisory  Bulletin  warning  manufacturers  that  they  may  be  subject  to  sanctions  under  the  federal  anti-kickback  statute  and/or  civil  monetary
penalty laws if they do not take appropriate steps to exclude Part D beneficiaries from using co-pay coupons. Accordingly, companies exclude these Part D
beneficiaries from using co-pay coupons.

On December 2, 2020, the 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 (PBMs), 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  PBMs  and
manufacturers. Implementation of this change and new safe harbors for point-of-sale reductions in price for prescription pharmaceutical products and PBM
service fees are currently under review by the current U.S. presidential administration and may be amended or repealed. Further, on December 31, 2020,
CMS published a new rule, effective January 1, 2023, requiring manufacturers to ensure the full value of co-pay assistance is passed on to the patient or
these dollars will count toward the Average Manufacturer Price and Best Price calculation of the drug. On May 21, 2021, PhRMA sued the HHS in the U.S.
District  Court  for  the  District  of  Columbia,  to  stop  the  implementation  of  the  rule  claiming  that  the  rule  contradicts  federal  law  surrounding  Medicaid
rebates. It is unclear how the outcome of this litigation will affect the rule. We cannot predict how the implementation of and any further changes to this
rule will affect our business.

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 ACA was enacted in
the United States. The ACA includes measures that have significantly changed, and are expected to continue to significantly change, the way healthcare is
financed by both governmental and private insurers. Among the provisions of the ACA of greatest importance to the pharmaceutical industry are that the
ACA:

33

  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 to 23.1% of average manufacturer price, or AMP, and
adding a new rebate calculation for “line extensions” (i.e., new formulations, such as extended release formulations) of solid oral dosage
forms of branded products, as well as potentially impacting their rebate liability by modifying the statutory definition of AMP.
Imposed a requirement on manufacturers of branded drugs to provide a 70% (increased pursuant to the Bipartisan Budget Act of 2018,
effective as of 2019) point-of-sale discount off the negotiated price of branded drugs dispensed to Medicare Part D beneficiaries in the
coverage gap (i.e., “donut hole”) as a condition for a manufacturer’s outpatient drugs being covered under Medicare Part D.
Extended a manufacturer’s Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed
care organizations.
Expanded the entities eligible for discounts under the 340B Drug Discount Program.
Established 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.
Imposed an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs, apportioned among
these entities according to their market share in certain government healthcare programs.
Established  a  new  Patient-Centered  Outcomes  Research  Institute  to  oversee,  identify  priorities  in,  and  conduct  comparative  clinical
effectiveness  research,  along  with  funding  for  such  research.  The  research  conducted  by  the  Patient-Centered  Outcomes  Research
Institute  may  affect  the  market  for  certain  pharmaceutical  products.  The  ACA  established  the  Center  for  Medicare  and  Medicaid
Innovation within CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially
including prescription drug spending.

Since its enactment, there have been numerous judicial, administrative, executive, and legislative challenges to certain aspects of the ACA. On June 17,
2021,  the  U.S.  Supreme  Court  dismissed  the  most  recent  judicial  challenge  to  the  ACA  brought  by  several  states  without  specifically  ruling  on  the
constitutionality of the ACA. Prior to the Supreme Court’s decision, President Biden issued an executive order to initiate a special enrollment period from
February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also
instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others,
reexamining  Medicaid  demonstration  projects  and  waiver  programs  that  include  work  requirements,  and  policies  that  create  unnecessary  barriers  to
obtaining  access  to  health  insurance  coverage  through  Medicaid  or  the  ACA.  It  is  unclear  how  other  healthcare  reform  measures  of  the  Biden
administration or other efforts, if any, to challenge, repeal or replace the ACA will impact our business. Prior to the Biden administration, on October 13,
2017, former President Trump signed an Executive Order which terminated the cost sharing subsidies that reimburse insurers under the ACA. The former
Trump  administration  concluded  that  cost-sharing  reduction,  or  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 will have on our business.

In addition, other legislative and regulatory changes have been proposed and adopted in the United States since the ACA was enacted:

34

On August 2, 2011, the U.S. Budget Control Act of 2011, among other things, included aggregate reductions of Medicare payments to
providers of 2% per fiscal year. These reductions went into effect on April 1, 2013 and, due to subsequent legislative amendments to the
statute, will remain in effect through 2030, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022 due
to the COVID-19 pandemic. Following the temporary suspension, a 1% payment reduction will occur beginning April 1, 2022 through
June 30, 2022, and the 2% payment reduction will resume on July 1, 2022.
On January 2, 2013, the U.S. American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced
Medicare payments to several types of providers.
On April 13, 2017, CMS published a final rule that gives states greater flexibility 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.
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  1  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 pharmaceutical manufacturer
to make its drug products available to eligible patients as a result of the Right to Try Act.
On  May  23,  2019,  CMS  published  a  final  rule  to  allow  Medicare  Advantage  Plans  the  option  of  using  step  therapy  for  Part  B  drugs
beginning January 1, 2020.
On  December  20,  2019  former  President  Trump  signed  into  law  the  Further  Consolidated  Appropriations  Act  (H.R.  1865),  which
repealed the Cadillac tax, the health insurance provider tax, and the medical device excise tax. It is impossible to determine whether
similar taxes could be instated in the future.

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. At a federal level, President Biden signed an Executive Order on July 9, 2021 affirming the
administration’s policy to (i) support legislative reforms that would lower the prices of prescription drug and biologics, including by allowing Medicare to
negotiate drug prices, by imposing inflation caps, and, by supporting the development and market entry of lower-cost generic drugs and biosimilars; and
(ii) support the enactment of a public health insurance option. Among other things, the Executive Order also directs HHS to provide a report on actions to
combat excessive pricing of prescription drugs, enhance the domestic drug supply chain, reduce the price that the Federal government pays for drugs, and
address price gouging in the industry; and directs the FDA to work with states and Indian Tribes that propose to develop section 804 Importation Programs
in accordance with the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, and the FDA’s implementing regulations. FDA released
such implementing regulations on September 24, 2020, which went into effect on November 30, 2020, providing guidance for states to build and submit
importation  plans  for  drugs  from  Canada.  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.  If  implemented,  importation  of  drugs  from  Canada  may  materially  and  adversely  affect  the  price  we  receive  for  any  of  our  product
candidates.  Further,  on  November  20,  2020  CMS  issued  an  Interim  Final  Rule  implementing  the  Most  Favored  Nation,  or  MFN,  Model  under  which
Medicare Part B reimbursement rates would have been 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. However, on December 29, 2021
CMS rescinded the Most Favored Nations rule. Additionally, on November 30, 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. Pursuant to court order, the removal and addition of the aforementioned
safe harbors were delayed and recent legislation imposed a moratorium on implementation of the rule until January 1, 2026. 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, both the Biden administration and Congress have indicated that they 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.

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.

35

 
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 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 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.

In addition, there have been several changes to the 340B drug pricing program, which imposes ceilings on prices that drug manufacturers can charge for
medications  sold  to  certain  health  care  facilities.  On  December  27,  2018,  the  District  Court  for  the  District  of  Columbia  invalidated  a  reimbursement
formula change under the 340B drug pricing program, and CMS subsequently altered the FYs 2019 and 2018 reimbursement formula on specified covered
outpatient drugs (“SCODs”). 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. However, most recently, 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), but was denied on October 16, 2020. Plaintiffs-appellees filed a petition for a
writ  of  certiorari  at  the  Supreme  Court  on  February  10,  2021.  On  Friday  July  2,  2021,  the  Supreme  Court  granted  the  petition.  It  is  unclear  how  these
developments could affect covered hospitals who might purchase our future products and affect the rates we may charge such facilities for our approved
products in the future, if any.

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.

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.

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 Resources

As of December 31, 2021, we had 294 full-time employees in the United States, 164 of whom were primarily engaged in sales and marketing, 85 of whom
were primarily engaged in general administration, and 45 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  personnel  across  all
departments  in  our  organization,  as  we  expand  the  commercialization  of  our  products.  Our  President  and  Chief  Operating  Officer  and  Vice  President,
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. the executive management team regularly updates our board of directors and its committees on
the operation and status of our human capital trends and activities.

Diversity, Equity and Inclusion

We are committed to building a company that provides an inclusive environment where we invite and encourage diverse perspectives, ideas, and people.
With  that  goal  in  mind,  we  have  established  a  committee  comprised  of  employees  and  sponsored  by  key  executive  team  members  to  build  a  strategy
designed to promote a diverse and inclusive work environment. We believe these initiatives and a workforce with diverse backgrounds, experiences and
viewpoints will continue to bring innovative solutions to the Company. In addition, we have sought to implement recruiting practices and to work with
recruiting partners who can help us best identify and attract diverse candidates. We continue to expand our systems to track key human capital metrics such
as  demographics,  diversity,  compensation  and  benefits,  and  engagement  and  to  think  of  new  ways  to  best  support  our  female  and  underrepresented
employees to help advance their careers.

Training and Talent Development

We believe that our employees are the key to our success, and we believe their development is what drives our growth and prosperity as a company. To
support employee development, as well as plan for short and long term business success, we review and update a company succession plan regularly and
we offer a number of development opportunities for our employees through various methods. Our succession plan is reviewed with the board annually. In
addition, upon joining the company, all new employees are required to become familiar with our policies, including our Code of Business Conduct and
Ethics and Employee Handbook, and complete compliance training, and existing employees are required to acknowledge current policies annually.

Compensation and Benefits

An important part of attracting and retaining key talent is competitive pay and benefits. To ensure our compensation and benefits programs are competitive,
we engage nationally recognized outside compensation and benefits consulting firms to independently evaluate the effectiveness of our programs and to
provide benchmarking against our peers within the industry. Our pay for

37

performance  philosophy  seeks  to  motivate  and  reward  employees  while  accomplishing  the  Company’s  short  and  long-term  strategic  goals.  As  part  of  a
robust performance management process, employees are evaluated both on what they accomplished and how they demonstrated our values. Annual salary
increases and incentive bonuses are based on both individual and corporate performance factors.

As a long-term incentive, to encourage our employees to think like owners and share in the Company’s long-term success, employees are granted equity in
the form of stock options or restricted stock units and can elect to participate in our employee stock purchase plan. Employees are generally eligible for
health insurance, paid and unpaid leaves including paid parental leave, paid caregiver leave, retirement plans with an employer contribution match, life and
disability/accident  coverage,  parking  or  commuter  assistance,  an  employee  assistance  program  providing  mental  health,  legal  and  financial  health
resources, and access to convenient COVID-19 testing.

Health and Safety

We are committed to the safety of our employees and the communities we serve. We provide regular health and safety training programs for employees,
which includes, upon on-boarding, an overview during new hire orientation, as well as ongoing training throughout the year.. Employees are trained on
workplace  safety,  including  security  and  inspection,  work  related  injuries  and  emergency  protocols  as  applicable  for  their  role  and  work  location.  In
addition, special health and safety training is conducted for laboratory staff.

Also, in response to the COVID-19 pandemic, we quickly implemented policies to protect our employees and provide solutions to enable our employees to
manage their work and personal responsibilities. In addition, a Pandemic Response Team was established, comprised of senior leaders, to help guide and
direct activities associated with local governance and business requirements during the COVID-19 pandemic. Refer to "Impact of COVID-19" included in
Item 7, "Management’s Discussion and Analysis of Financial Condition and Results of Operations" for information on Human Capital Management actions
taken by the Company in response to the COVID-19 pandemic.

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 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 Pandemic

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, evolved into a global pandemic. The coronavirus spread globally,
and the impact of the outbreak is continually evolving, particularly in light of new variants of COVID-19.

As a result of the ongoing COVID-19 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 certain of our products 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  were  engaging  with  these  customers  remotely,  via
webinar programs and virtual meetings, as we sought 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. With the emergence of
variants and, in some areas, lack of acceptance of vaccines, some areas implement or reintroduce restrictions, which may impact our sales and
marketing personnel's access to customers. Remote interactions may be less effective as in-person interactions. In addition, several conferences
and  other  programs  at  which  we  intended  to  market  our  products  have  been  postponed,  canceled  and/or  transitioned  to  virtual  meetings.  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 ("CMOs") for the manufacturing of Gvoke, Keveyis, and
Recorlev,  as  well  as  to  perform  third-party  logistics  functions,  including  warehousing  and  distribution  of  Gvoke,  Keveyis,  and  Recorlev.  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 or supply chain issues, including
staffing  shortages,  production  slowdowns  and  disruptions  in  delivery  systems,  our  supply  chain  may  be  disrupted,  limiting  our  ability  to
manufacture commercial quantities.
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  have  since  reopened  our  offices  on  a  voluntary  basis  and  have  implemented  safety  measures
designed  to  comply  with  applicable  federal,  state  and  local  guidelines  in  response  to  the  COVID-19  pandemic.  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 cybersecurity 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.
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.

39

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 deprioritization 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.

Since the beginning of the COVID-19 pandemic, three vaccines for COVID-19 have received Emergency Use Authorization by the FDA and two of those
later received marketing approval. Additional vaccines may be authorized or approved in the future. 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 emergence of
new  variants,  the  acceptance  and  availability  of  vaccines  in  various  geographies,  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 few 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 debt issuances. We commercially launched Gvoke PFS in November 2019, Gvoke HypoPen in July 2020 and Recorlev in January
2022. Strongbridge commercially launched Keveyis in April 2017. We are in the early stages of commercializing our biopharmaceutical products and have
a  limited  operating  history.  Biopharmaceutical  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 biopharmaceutical 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
biopharmaceutical 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  execute  our  commercialization  strategy  and  may  not  be  successful  in  doing  so.  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.

We have incurred significant losses in every fiscal year since inception. For the year ended December 31, 2021 and 2020, we reported a net loss of $122.7
million and $91.1 million, respectively. In addition, our accumulated deficit as of December 31, 2021 was $460.1 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.

We expect to continue to incur significant operating expenses as we continue the commercialization of Gvoke, Keveyis and Recorlev, develop, enhance and
commercialize  new  products  (including  Recorlev),  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, Keveyis and Recorlev commercial strategies in the U.S.;
continue our research and development efforts;
seek regulatory approval for new product candidates and product enhancements;

40

<
<

integrate the combined company; and
continue to operate as a public company.

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.  In  February  2021  the  European  Commission  ("EC")  granted  marketing  authorization  and  in  April  2021  the  United  Kingdom's
Medicines and Healthcare products Regulatory Agency approved Ogluo for the treatment of severe hypoglycemia in adults, adolescents, and children aged
two years and over with diabetes mellitus. On July 19, 2021, we announced that we had entered into an exclusive agreement with Tetris Pharma Limited
(“Tetris”) for the commercialization of Ogluo in the European Economic Area, United Kingdom, and Switzerland (the “Territory”). Under the terms of the
applicable agreements, Xeris will be responsible for product supply and Tetris will be responsible for commercialization of Ogluo in the Territory. Tetris
launched Ogluo in the United Kingdom in December 2021. Our ability to generate revenue from Gvoke, Keveyis and Recorlev and our product candidates
and  to  transition  to  profitability  and  generate  positive  cash  flows  is  uncertain  and  depends  on  the  successful  commercialization  of  Gvoke,  Keveyis  and
Recorlev and any of our product candidates for which we obtain marketing approval. 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,  Keveyis  and  Recorlev,  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 from Gvoke, Keveyis and Recorlev, and our
product candidates, if successfully developed and approved, depends on a number of factors, including, but not limited to, our ability to:

<

<

<

<

<

obtain commercial quantities of our products 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, Keveyis and Recorlev. Regardless of
these expenditures, our products and our product candidates, if approved, may not be commercially successful. Although we generate revenue from Gvoke,
Keveyis and Recorlev, if we are unable to generate sufficient product revenue, we will not become profitable and may be unable to continue operations
without continued funding.

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.

Biopharmaceutical  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, Keveyis and Recorlev and expect to
continue  to  incur  such  expenses  for  our  products,  as  well  as  for  any  of  our  product  candidates,  if  approved.  We  expect  to  require  additional  capital  to
complete the clinical trials associated with our product candidates and begin commercialization efforts, if approved. Accordingly, we may need additional
funding in connection with our continuing operations. 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 and/or sales and marketing activities. Market volatility resulting from the ongoing
COVID-19 pandemic or other factors could also adversely impact our ability to access capital as and when needed.

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,

Inc., 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 our
products 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. 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, or
repurchase  our  Convertible  Notes  for  cash  following  a  fundamental  change,  and  our  existing  and  future  indebtedness  may  limit  our  ability  to
repurchase the Convertible Notes.

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, 2021, the outstanding balance
of Convertible Notes was $47.2 million. The Convertible Notes are governed by the terms of a base indenture for senior debt securities dated June 30, 2020
(the “Base Indenture”), as supplemented by the first supplemental indenture thereto dated June 30, 2020 and the second supplemental indenture thereto
dated October 5, 2021 ("the Supplemental Indentures" and together with the Base Indenture, the "Indenture"), each 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.

42

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 other existing or future indebtedness, which may
result  in  that  other  indebtedness  becoming  immediately  payable  in  full.  For  instance,  a  fundamental  change  without  lender  consent  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.

In addition, we have $43.5 million outstanding under our Amended Loan Agreement as of December 31, 2021. 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 our
business, including our prospect of repayment of our 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. In addition, our lenders could seek to enforce their security interests in any collateral securing such indebtedness.

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")  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 commercial 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 products, Gvoke, Keveyis and Recorlev, in the United
States. Our business and future success are substantially dependent on our ability to generate and increase product revenues in the near term. Our estimates
of the potential market opportunity for Gvoke, Keveyis, Recorlev 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. 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. Our product candidates are in various 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.
There is no guarantee that the infrastructure, systems, processes, policies, relationships and materials we have built for the commercialization of Gvoke,
Keveyis  and  Recorlev  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. See the
section entitled, “Business — Coverage and Reimbursement”.

Even if all regulatory approvals are obtained, the commercial success of our products and product candidates will depend 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:

44

<

<

<

<

<

<

<

<

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 a 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;
we may be subject to litigation or products 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.

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  developed  our  commercial  infrastructure  for  the  sales,  marketing  and  distribution  of  Gvoke,  Keveyis,  and  Recorlev.  In  order  to  successfully
commercialize  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 established and recently expanded our
sales force to market our products 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,  obtain  access  to  an
adequate number of physicians and persuade them to prescribe our products and any product candidates that receive regulatory approval, 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  would  adversely  impact  the  commercialization  of  Gvoke,
Keveyis and Recorlev and the launch and commercialization of our product candidates, if approved.

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.

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 Actions and Market Acceptance

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

We do not currently own or operate any manufacturing facilities for the production of Gvoke, Keveyis, Recorlev for commercial supply or our product
candidates for use in clinical trials. We rely on third-party suppliers to manufacture and supply our products and our product candidates. For Gvoke, 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.  Taro  Pharmaceuticals  U.S.A.,  Inc.  ("Taro")  produces  all  of  our
requirements for Keveyis. The agreement with Taro may extend beyond the orphan exclusivity period unless terminated by either party pursuant to the
terms of the agreement. If terminated by Taro at the conclusion of the orphan exclusivity period, we will need to find a new third party to manufacture
Keveyis or manufacture the product ourselves. Similarly for Recorlev, we rely on a number of single-source suppliers, such as Regis Technologies, Inc. for
API and Xcelience, LLC (“Lonza”) for finished drug product. We rely on other third parties to manufacture our product candidates for use in clinical trials.
If any of these vendors is unable or unwilling to meet our future requirements, we may not be able to manufacture and/or supply our products in a timely
manner. Our current arrangements with these manufacturers are terminable by such manufacturers, subject to certain notice provisions.

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, components 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 and our suppliers’ ability to
procure sufficient supplies for the manufacture of our commercial products or our product candidates continues to evolve and there can be no assurances
that there will not be disruptions to supply in the future. 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, political instability or any other
cause could materially impair our ability to manufacture our products and to distribute our products to customers. For example, we have a global supply
chain  and  manufacture  some  components  of  our  products  outside  the  United  States,  including  without  limitation,  Taiwan.  Any  interruption  in  the
production or delivery of our supplies could reduce sales of our products and increase our costs and 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.

Gvoke and some of our product candidates are drug-device combination products that are regulated under the drug regulations of the Federal Food, Drug,
and Cosmetic Act (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, CGMP
and/or  QSRs  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 the FDA or such foreign regulatory authorities do not approve these facilities for the manufacture of our products or
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 our products or develop, obtain regulatory approval for or market our product candidates, if approved.

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.

46

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;
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; and
the possibility of breach or termination of a manufacturing agreement or purchase order by the third party.

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 CMOs 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. Additionally, 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.

47

Reimbursement decisions by third-party payors and consolidation within the healthcare industry and among competitors more generally 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
and pricing pressure may impact our ability to sell our products at prices necessary to support our current business strategies.

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 on behalf of 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 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.  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.  See  the  sections  entitled,  “Business  —  Coverage  and
Reimbursement” and “Business — Healthcare Reform”.

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.

There is also significant uncertainty related to the insurance coverage and reimbursement of newly approved products, and coverage may be more limited
than the purposes for which the medicine is approved by the FDA or comparable foreign regulatory authorities. In the United States, the principal decisions
about  reimbursement  for  new  medicines  are  typically  made  by  the  Centers  for  Medicare  &  Medicaid  Services,  or  CMS,  an  agency  within  the  U.S.
Department of Health and Human Services. CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare, and
private payors tend to follow CMS to a substantial degree. Factors payors consider in determining reimbursement are based on whether the product is (i) a
covered benefit under its health plan; (ii) safe, effective and medically necessary; (iii) appropriate for the specific patient; (iv) cost-effective; and (v) neither
experimental nor investigational.

New  requirements  by  third-party  payors  include:  (i)  net  prices  for  drugs  may  be  reduced  by  mandatory  discounts  or  rebates  required  by  government
healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at
lower prices than in the United States; (ii) third-party payors are increasingly requiring that drug companies provide them with predetermined discounts
from  list  prices  and  are  challenging  the  prices  charged  for  medical  products.  We  cannot  be  sure  that  reimbursement  will  be  available  for  any  product
candidate  that  we  commercialize  and,  if  reimbursement  is  available,  the  level  of  reimbursement;  and  (iii)  many  pharmaceutical  manufacturers  must
calculate and report certain price metrics to the government, such as average manufacturer price, or AMP, and Best Price. Penalties may apply when such
metrics are not submitted accurately and timely. Further, these prices for drugs may be reduced by mandatory discounts or rebates required by government
healthcare programs.

In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing
drug  pricing  vary  widely  from  country  to  country.  For  example,  the  European  Union  provides  options  for  its  Member  States  to  restrict  the  range  of
medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use.
To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost effectiveness of a
particular  product  candidate  to  currently  available  therapies.  A  Member  State  may  approve  a  specific  price  for  the  medicinal  product  or  it  may  instead
adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that
any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements
for any of our product candidates. Historically, products launched in the European Union do not follow price structures of the U.S. and generally prices
tend to be significantly lower.

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. 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.

48

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.

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.

The success of Gvoke, Keveyis, Recorlev and our other product candidates will be dependent on its proper use by patients, healthcare practitioners and
caregivers.

While  we  have  designed  our  products  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  our  products  were  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 our products by
patients, healthcare practitioners and caregivers, we may not be able to achieve market acceptance or effectively commercialize our products. In addition,
even  in  the  event  of  proper  use  of  our  products,  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.

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. 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.  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.

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 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.

50

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 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.

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 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. Specifically, on March 23, 2020, a small subset of “biological products” approved
under the Federal Food, Drug, and Cosmetic Act, such as insulin, which historically were approved as drugs, transitioned to being regulated as biological
products. Being regulated as biological products enables transition products to serve as the reference product for biosimilar or interchangeable products
approved through the abbreviated licensure pathway. The transition is a regulatory action in which the approved drug application for a transition biological
product will be “deemed” to be a biologics license application. Thus our XeriSol pramlintide-insulin co-formulation which would have previously been
reviewed  through  a  505(b)(2)  NDA  is  instead  now  required  to  be  approved  under  the  PHS  Act.  If  our  other  product  candidates  do  not  meet  the
requirements of Section 505(b)(2) or are otherwise ineligible or become 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

51

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.

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.

Gvoke, Keveyis, Recorlev 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.  In  our  clinical  trials  of  Recorlev,  the  most  common  adverse  reactions  (incidence  >  20%)  were  nausea/vomiting,
hypokalemia,  hemorrhage/contusion,  systemic  hypertension,  headache,  hepatic  injury,  abnormal  uterine  bleeding,  erythema,  fatigue,  abdominal
pain/dyspepsia, arthritis, upper respiratory infection, myalgia, arrhythmia, back pain, insomnia/sleep disturbances, and peripheral edema the most common
adverse  reactions  (incidence  >  20%)  were  nausea/vomiting,  hypokalemia,  hemorrhage/contusion,  systemic  hypertension,  headache,  hepatic  injury,
abnormal  uterine  bleeding,  erythema,  fatigue,  abdominal  pain/dyspepsia,  arthritis,  upper  respiratory  infection,  myalgia,  arrhythmia,  back  pain,
insomnia/sleep disturbances, and peripheral edema. These adverse events can be dose-dependent and may increase in frequency and severity if we increase
the dose to increase efficacy. 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 products liability claims. They could also adversely affect physician or patient acceptance of our product candidates.
Any of these occurrences may harm our business, financial condition and prospects.

52

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

<

<

<

<

<

<

<

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 products 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.

We  have  received  orphan  drug  designation  for  Keveyis,  Recorlev  and  certain  of  our  product  candidates  with  respect  to  certain  indications  and  may
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. We will
continue to rely on orphan drug exclusivity in the marketing and sales of Keveyis until it expires on August 7, 2022 and intend to rely on orphan drug
exclusivity and, if granted, new chemical entity (“NCE”) exclusivity in the marketing and sale of Recorlev. 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. 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. 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. 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.

53

 
 
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 Gvoke, Keveyis and Recorlev in the United States and the EMA and MHRA approval of Ogluo in the European Union
and the United Kingdom, we may not be able to obtain or maintain foreign regulatory approvals to market our products in other countries.

We do not have any products other than Gvoke, Keveyis and Recorlev 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 and the United Kingdom. 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  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.  See  the  section  entitled,  “Business  —  Healthcare
Reform”.

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.

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. There has
recently  been  intense  publicity  regarding  the  pricing  of  pharmaceutical  products  generally,  including  publicity  and  pressure  resulting  from  the  prices
charged  for  new  products  as  well  as  price  increases  for  older  products  that  the  government  and  public  deem  excessive.  We  may  experience  downward
pricing  pressure  on  the  price  of  our  products  due  to  social  or  political  pressure  to  lower  the  cost  of  drugs,  which  could  reduce  our  revenue  and  future
profitability.  Many  companies  in  our  industry  have  received  governmental  requests  for  documents  and  information  relating  to  drug  pricing  and  patient
support  programs,  including  Strongbridge,  which  is  cooperating  with  these  voluntary  requests  for  information.  We  could  incur  significant  expense  and
experience reputational harm as a result of these or other similar future inquiries, as well as reduced market acceptance and demand for our products, which
could harm our ability to market our products in the future. These factors could also result in changes in our product pricing and distribution strategies,
reduced demand for our products and/or reduced reimbursement of products, including by federal health care programs such as Medicare and Medicaid and
state health care programs.

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

54

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 of those product candidates for which we seek 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,  or  acquire  additional  product  candidates  or  enter  into
collaborations or other commercial agreements 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,
and evaluate other commercial relationships through collaborations or other strategic agreements. 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. 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 obtain approval of 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. In addition, 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. We face significant competition in seeking appropriate collaborators. We have limited resources to identify and
execute the acquisition or in-licensing of third-party products, businesses and technologies or enter into collaborations or other strategic arrangements 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.

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 and applicable product tracking
and  tracing  requirements.  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  submitted  a  response  to  the  FDA  regarding  our  plan  to  revise  the
advertisement at issue. The FDA completed evaluation of our response and confirmed that we have addressed all the violations contained in the untitled
letter.

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.

56

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. See the section entitled, “Business — Other Healthcare Laws and Compliance Requirements”.

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,  diminished  profits  and  future  earnings,  reputational  harm  and  the  curtailment  or  restructuring  of  our
operations, and imprisonment, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other
agreement  to  resolve  allegations  of  non-compliance  with  these  laws,  any  of  which  could  adversely  affect  our  ability  to  operate  our  business  and  our
financial  results.  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.

Third party patient assistance programs that receive financial support from companies have become the subject of enhanced government and regulatory
scrutiny.  Government  enforcement  agencies  have  shown  increased  interest  in  pharmaceutical  companies'  product  and  patient  assistance  programs,
including reimbursement support services, and a number of investigations into these programs have resulted in significant civil and criminal settlements.
The  U.S.  government  has  established  guidelines  that  suggest  that  it  is  lawful  for  pharmaceutical  manufacturers  to  make  donations  to  charitable
organizations who provide co-pay assistance to Medicare patients, provided that such organizations, among other things, are bona fide charities, are entirely
independent of and not controlled by the manufacturer, provide aid to applicants on a first-come basis according to consistent financial criteria and do not
link aid to use of a donor's product. However, donations to patient assistance programs have received some negative publicity and have been the subject of
multiple  government  enforcement  actions,  related  to  allegations  regarding  their  use  to  promote  branded  pharmaceutical  products  over  other  less  costly
alternatives. Specifically, in recent years, there have been multiple settlements resulting out of government claims challenging the legality of their patient
assistance  programs  under  a  variety  of  federal  and  state  laws.  It  is  possible  that  we  may  make  grants  to  independent  charitable  foundations  that  help
financially needy patients with their premium, co-pay, and co-insurance obligations. If we choose to do so, and if we or our vendors or donation recipients
are deemed to fail to comply with relevant laws, regulations or evolving government guidance in the operation of these programs, we could be subject to
damages,  fines,  penalties,  or  other  criminal,  civil,  or  administrative  sanctions  or  enforcement  actions.  We  cannot  ensure  that  our  compliance  controls,
policies, and procedures will be sufficient to protect against acts of our employees, business partners, or vendors that may violate the laws or regulations of
the  jurisdictions  in  which  we  operate.  Regardless  of  whether  we  have  complied  with  the  law,  a  government  investigation  could  impact  our  business
practices, harm our reputation, divert the attention of management, increase our expenses, and reduce the availability of foundation support for our patients
who  need  assistance.  Further,  it  is  possible  that  changes  in  insurer  policies  regarding  co-pay  coupons  and/or  the  introduction  and  enactment  of  new
legislation  or  regulatory  action  could  restrict  or  otherwise  negatively  affect  these  patient  support  programs,  which  could  result  in  fewer  patients  using
affected products, and therefore could have a material adverse effect on our sales, business, and financial condition. Although a number of these and other
proposed  measures  may  require  authorization  through  additional  legislation  to  become  effective,  and  the  current  U.S.  presidential  administration  may
reverse or otherwise change these measures, both the current U.S. presidential administration and Congress have indicated that they will continue to seek
new legislative measures to control drug costs. We cannot predict how the implementation of and any further changes to this rule will affect our 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

57

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.

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.

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.

58

For example, Gvoke has 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 received approval by the FDA of its dasiglucagon auto-injector Zegalogue  in March 2021 and launched in June 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.

In addition, Keveyis is an oral carbonic anhydrase inhibitor, that was approved in the United States to treat hyperkalemic, hypokalemic and related variants
of PPP. Acetazolamide, another oral carbonic anhydrase inhibitor, is used frequently off-label for the prophylactic and sometimes acute treatment of PPP.
Potassium  supplements,  are  indicated  for  use  in  hypokalemic  periodic  paralysis  in  the  United  States  and  are  frequently  used  either  chronically  or  for
emergency treatment of episodes in that form of PPP. Several other types of drugs have been reported to have benefits for chronic or acute use in one or
more than one PPP variant, including potassium-sparing diuretics, beta receptor agonists, mexelitine and other sodium channel blockers, and others. We are
not aware of drugs currently in development for prophylactic chronic treatment of PPP.

We  are  currently  aware  of  various  companies  that  are  marketing  existing  drugs  that  may  compete  with  Recorlev  such  as  Corcept  Therapeutics  and
Recordati. The treatment of endogenous Cushing's syndrome patients who fail or are ineligible for surgery in the United States and Europe are: Korlym
(mifepristone) marketed by Corcept Therapeutics in the United States; Signifor LAR (pasireotide) and Isturisa (osilodrostat), all marketed by Recordati in
the  United  States  and  European  Union;  and  ketoconazole,  metyrapone  and  mitotane  marketed  by  HRA  in  the  European  Union.  Corcept  is  developing
relacorilant,  a  second-generation  glucocorticoid  receptor  modulator;  currently  in  Phase  3.  Ketoconazole  is  used  off-label  for  treatment  of  Cushing's
syndrome in the United States. Regulatory approval of ketoconazole for the treatment of endogenous Cushing's syndrome in the United States, which is not
currently being sought by any sponsor to our knowledge, could significantly increase competition for Recorlev due to the similar mechanisms of action
between the drug products.

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. Laws have also been enacted to facilitate the development of generic drugs and biologics
based off recently approved NDAs and BLAs. The Creating and Restoring Equal Access to Equivalent Samples Act (“CREATES Act”) was enacted in
2019 requiring sponsors of approved NDAs and BLAs to provide sufficient quantities of product samples on commercially reasonable, market-based terms
to entities developing generic drugs and biosimilar biological products. The law establishes a private right of action allowing developers to sue application
holders that refuse to sell them product samples needed to support their applications. If we are required to provide product samples or allocate additional
resources  to  responding  to  such  requests  or  any  legal  challenges  under  this  law,  our  business  could  be  adversely  impacted.  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.  We  will  continue  to  rely  on  orphan  drug  exclusivity  in  the
marketing and sales of Keveyis through expiration of orphan drug exclusivity in August, 2022 and intend to rely on orphan drug exclusivity and NCE, if
available, exclusivity in the marketing and sale of Recorlev. While we applied for NCE exclusivity for Recorlev under section 505(u) of the FDCA, the
FDA may determine that the Recorlev application does not meet the eligibility criteria under 505(u) for NCE exclusivity.

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  the  use,  formulation  and  structure  of  our  proprietary  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.  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.
Moreover,  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.

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.

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.

60

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 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.

We have entered into a license agreement with a third party (and may, in the future, enter into additional such license agreements with other 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.

61

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

Because we rely on third parties to develop and manufacture our product candidates, we must, at times, share trade secrets with them. We seek to protect
our  proprietary  technology  in  part  by  entering  into  confidentiality  agreements  and,  if  applicable,  material  transfer  agreements,  collaborative  research
agreements, consulting agreements or other similar agreements with our collaborators, advisors, employees, and consultants prior to beginning research or
disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, such as
trade  secrets.  Despite  the  contractual  provisions  employed  when  working  with  third  parties,  the  need  to  share  trade  secrets  and  other  confidential
information increases the risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology of others, or are
disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor's
discovery of our trade secrets or other unauthorized use or disclosure would impair our competitive position and may harm our business.

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.

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.

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

62

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.

Thus, 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

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 depends in part on our ability to develop, manufacture, market and sell our products that have been approved for sale, and to use
our proprietary technology without alleged or actual infringement, misappropriation or other violation of the patents and proprietary rights of third parties.
There  have  been  many  lawsuits  and  other  proceedings  involving  patent  and  other  intellectual  property  rights  in  the  biotechnology  and  pharmaceutical
industries, including patent infringement lawsuits, interferences, oppositions and reexamination proceedings before the USPTO, and corresponding foreign
patent offices. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we
will market products and are developing product candidates. Some claimants, who may include our competitors in both the United States and abroad, may
have substantially greater resources than we do and may be able to sustain the costs of complex intellectual property litigation to a greater degree and for
longer periods of time than we could. In addition, patent holding companies that focus solely on extracting royalties and settlements by enforcing patent
rights  may  target  us.  As  the  biotechnology  and  pharmaceutical  industries  expand  and  more  patents  are  issued,  the  risk  increases  that  our  products  and
product candidates may be subject to claims of infringement of the intellectual property rights of third parties.

We  cannot  be  sure  that  we  know  of  each  and  every  patent  and  pending  application  in  the  United  States  and  abroad  that  is  relevant  or  necessary  to  the
commercialization of Gvoke, Keveyis Recorlev, or our product candidates. 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. Because patent applications can take many years to issue,
there may be currently pending patent applications that may later result in issued patents upon which our products or product candidates may infringe. In
addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. If any third-party patents were
held by a court of competent jurisdiction to cover the manufacturing process of any of our products or product candidates, any compositions formed

63

during the manufacturing process or any final product itself, the holders of any such patents may be able to block our ability to commercialize such product
or  product  candidate  unless  we  obtained  a  license  under  the  applicable  patents,  or  until  such  patents  expire  or  are  finally  determined  to  be  invalid  or
unenforceable. Similarly, if any third-party patents were held by a court of competent jurisdiction to cover aspects of our compositions, formulations, or
methods  of  treatment,  prevention  or  use,  the  holders  of  any  such  patents  may  be  able  to  block  our  ability  to  develop  and  commercialize  the  applicable
product or product candidate unless we obtained a license or until such patent expires or is finally determined to be invalid or unenforceable. In either case,
such a license may not be available on commercially reasonable terms, or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby
giving our competitors access to the same technologies licensed to us.

We  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.

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.

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. Furthermore, 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.

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.  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.

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.

We  may  also  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

64

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 most of 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
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).

However, 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.

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.

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

We may not be able to enforce our intellectual property rights throughout the world. Filing, prosecuting, enforcing and defending patents on our products
and  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 products and 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

65

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.

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  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 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.  Changes  in  patent  statutes,  regulations  promulgated  under  them,  and  court  holdings  interpreting  the  statutes  and  regulations  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.
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.

Further, 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. Alternatively, a petition for inter partes review can be filed after the nine-month period for filing a post-grant review
petition has expired. 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 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 could result in a loss of the challenged patent right to us.

Risks Related to Employee Matters, Managing Growth and Ongoing Operations

Risks Related to Ongoing Operations

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.
Since  March  2020  when  foreign  and  domestic  inspections  of  facilities  were  largely  placed  on  hold  due  to  the  COVID-19  pandemic,  the  FDA  has  been
working  to  resume  routine  surveillance,  bioresearch  monitoring  and  pre-approval  inspections  on  a  prioritized  basis.  Since  April  2021,  the  FDA  has
conducted limited inspections and employed remote interactive evaluations, using risk management methods, to meet user fee commitments and goal dates.
Ongoing  travel  restrictions  and  other  uncertainties  continue  to  impact  oversight  operations  both  domestic  and  abroad  and  it  is  unclear  when  standard
operational levels will resume. The FDA is continuing to complete mission-critical work, prioritize other higher-tiered inspectional needs (e.g., for-cause
inspections), and carry out surveillance inspections using risk-based approaches for evaluating public health. Should FDA determine that an inspection is
necessary  for  approval  and  an  inspection  cannot  be  completed  during  the  review  cycle  due  to  restrictions  on  travel,  and  the  FDA  does  not  determine  a
remote  interactive  evaluation  to  be  appropriate,  the  agency  has  stated  that  it  generally  intends  to  issue,  depending  on  the  circumstances,  a  complete
response  letter  or  defer  action  on  the  application  until  an  inspection  can  be  completed.  During  the  COVID-19  public  health  emergency,  a  number  of
companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. During the
COVID-19  public  health  emergency,  the  FDA  has  worked  to  ensure  timely  reviews  of  applications  for  medical  products  in  line  with  its  user  fee
performance  goals  and  conduct  mission  critical  domestic  and  foreign  inspections  to  ensure  compliance  of  manufacturing  facilities  with  FDA  quality
standards.  However,  the  FDA  may  not  be  able  to  continue  its  current  pace  and  approval  timelines  could  be  extended,  including  where  a  pre-approval
inspection or an inspection of clinical sites is required and due to the ongoing COVID-19 pandemic and travel restrictions FDA is unable to complete such
required inspections during the review period. 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 Relating to the Integration of the Combined Company

We may not be able to successfully integrate and combine the businesses of Xeris and Strongbridge following the completion of the Transactions and
we may not realize the anticipated benefits from the Transactions.

On  October  5,  2021,  we  completed  the  previously  announced  acquisition  and  merger  between  Xeris  Pharma  and  Strongbridge  as  contemplated  by  the
Transaction Agreement, dated as of May 24, 2021, by and among us, Xeris, Strongbridge and Wells MergerSub, Inc. (the “Transaction Agreement”). We
entered  into  the  Transaction  Agreement  with  the  expectation  that  the  Transactions  will  result  in  various  benefits,  including  certain  cost  savings  and
operational  efficiencies  or  synergies.  To  realize  these  anticipated  benefits,  the  businesses  of  Xeris  and  Strongbridge  must  be  successfully  integrated.
Historically, Xeris and Strongbridge have been independent companies. The integration process to date has been complex and time consuming and may
require substantial additional resources and effort. If the companies are not successfully integrated, the anticipated benefits of the Transactions may not be
realized  fully  (or  at  all)  or  may  take  longer  to  realize  than  expected.  A  variety  of  factors  may  adversely  affect  our  ability  to  fully  realize  the  expected
operating synergies, savings and other benefits of the Transactions, including, without limitation:

•

•

•

latent  impacts  resulting  from  the  diversion  of  management  team’s  attention  from  ongoing  business  concerns  as  a  result  of  the  devotion  of
management’s attention to the Transactions;

difficulties in achieving anticipated cost savings, synergies, business opportunities and growth prospects;

the possibility of faulty assumptions underlying expectations regarding the integration process, including with respect to the intended tax efficient
transactions;

67

•

•

•

•

•

•

unanticipated  issues,  costs  and  strained  resources  in  integrating  information  technology,  communications  programs,  financial  procedures  and
operations, and other systems, procedures and policies;

difficulties in managing a larger combined company, addressing differences in business culture and retaining key personnel and employees;

unanticipated changes in applicable laws and regulations;

uncertainty that employees may experience about their roles within the combined company, which may have an additional adverse effect on our
ability to attract or retain key management personnel and other key employees;

coordinating geographically separate organizations; and

failure to otherwise integrate Xeris’ and Strongbridge’s respective businesses.

Some of these factors will be outside of our control and any one of them could result in increased costs and diversion of management’s time and energy, as
well  as  decreases  in  the  amount  of  expected  revenue  which  could  materially  impact  our  business,  financial  conditions  and  results  of  operations.  The
integration process and other disruptions resulting from the Transactions may also adversely affect our relationships with employees, suppliers, customers,
licensors and others, and difficulties in integrating the separate businesses or regulatory functions could harm the reputation of the combined company. If
we are not able to adequately address integration challenges, we may be unable to successfully integrate our operations or realize the anticipated benefits of
the Transactions.

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,
Steven  Pieper,  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,  Global  Development  and  Medical  Affairs,  and  Beth  Hecht,  our  Chief  Legal  Officer  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
commercialize our products and to develop and commercialize our product candidates will be limited.

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.

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

We have a number of convertible securities outstanding, including CVRs, Convertible Notes and warrants, and the conversion of such securities into shares
of our 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, CVRs and warrants. During the second half of 2020,
$39.1  million  in  principal  amount  of  Convertible  Notes  were  converted  into  13,171,791  shares  of  our  common  stock.  As  of  December  31,  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

69

 
 
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.

The CVRs represent contingent additional consideration of up to $1.00 for each CVR, payable to CVR holders, to satisfy future performance milestones,
settleable in cash, common stock, or a combination of cash and common stock, at our sole election. If the performance milestones are met and we elect to
pay the CVR consideration in common stock, it could have a dilutive effect to our earnings per share and cause our share price to go down.

Upon  completion  of  the  Acquisition,  each  outstanding  and  unexercised  Strongbridge  warrant  (except  private  placement  warrants)  was  assumed  by  the
Company such that, upon exercise, the applicable holders will have the right to have delivered to them the reference property (as such term is defined in the
Strongbridge assumed warrants). Each outstanding and unexercised Strongbridge private placement warrant was assumed by the Company such that the
applicable  holders  will  have  the  right  to  subscribe  for  the  Company's  Shares,  in  accordance  with  certain  terms  of  the  Strongbridge  private  placement
warrants. The conversion of these warrants into shares of our common stock could have a dilutive effect that could cause our share price to go down.

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,  2021,  we  had  federal  net  operating  loss  carryforwards  of  $475.7  million  and  various  state  net  operating  loss  carryforwards  of
$309.7 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, 2021. As of December 31, 2021, we had $5.4 million
and $2.5 million of federal and state income tax credits, respectively, to reduce future tax liabilities. If not utilized, the $5.4 million in federal income tax
credits  will  begin  to  expire  in  2025,  and  the  $2.5  million  of  state  research  and  development  credits  will  begin  to  expire  in  2022,  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. 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 and 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 current or former 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 under the Securities Act or the Securities Exchange Act of 1934, as amended. In addition, our amended and restated bylaws further provide that the
federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities
Act (the “Federal Forum Provision”).

71

This forum selection provision may limit a shareholder’s ability to bring a claim in a judicial forum that it finds favorable or cost-efficient for disputes with
us  or  any  of  our  directors,  officers,  employees  or  agents,  which  may  discourage  such  lawsuits,  or  increase  the  costs  to  a  shareholder  of  bringing  such
lawsuits, against us and such persons.

The enforceability of forum selection provisions in other companies’ articles of incorporation, bylaws or similar governing documents has been challenged
in legal proceedings, and it is possible that in connection with any action a court could find the forum selection provisions contained in our bylaws to be
inapplicable  or  unenforceable  in  such  action.  If  a  court  were  to  find  these  forum  selection  provisions  inapplicable  or  unenforceable,  we  may  incur
additional  costs  associated  with  resolving  such  matters  in  other  jurisdictions,  which  could  adversely  impact  our  operating  or  financial  condition  or
performance.

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, including ransomware,
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  or  other  sensitive  information,  which  could  cause  significant  damage  to  our
reputation, lead to claims against the Company and ultimately harm our business.

If products 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  products
liability claims against us. We maintain total products liability insurance coverage of $15.0 million.

Although we maintain products 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 products liability claims, which could materially
harm our business, financial condition or results of operations. In addition, 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.

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.

Products  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. Products liability claims could also result in investigation, prosecution or enforcement action by the DOJ or other federal or state
government agencies.

72

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.

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.

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. Analysts who publish information about our common stock may have 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 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

73

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 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
non-affiliates 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.

Our data collection and processing activities are governed by restrictive regulations governing the use, processing and, in certain jurisdictions, cross-
border transfer of personal information.

We may be subject to European, UK, US federal, state, and foreign data protection laws and regulations (i.e., laws and regulations that address privacy and
data security). We have personnel located in Ireland and have conducted and may in the future conduct clinical trials in the European Union ("EU") and/or
the United Kingdom (“UK”) subjecting us to additional privacy restrictions and data protection requirements. The collection and use of personal health data
in the EU are governed by the provisions of the General Data Protection Regulation ("GDPR"), as well as other national data protection legislation in force
in relevant Member States (including the UK GDPR and the Data Protection Act 2018 in the UK). These laws impose a broad range of strict requirements
on  companies  subject  to  the  GDPR,  such  as  including  requirements  relating  to  having  legal  bases  for  processing  personal  data  relating  to  identifiable
individuals and transferring such information outside the European Economic Area, or EEA (or in the case of the UK GDPR, outside of the UK), providing
details to those individuals regarding the processing of their personal data, implementing safeguards to keep personal data secure, having data processing
agreements  with  third  parties  who  process  personal  data,  providing  information  to  individuals  regarding  data  processing  activities,  responding  to
individuals’  requests  to  exercise  their  rights  in  respect  of  their  personal  data,  obtaining  consent  of  the  individuals  to  whom  the  personal  data  relates,
reporting security and privacy breaches involving personal data to the competent national data protection authority and affected individuals, appointing data
protection officers, conducting data protection impact assessments, and record-keeping. The GDPR may impose additional responsibility and liability in
relation to personal data that we process and we may be required to put in place additional mechanisms ensuring compliance with the new data protection
rules. This may be onerous and adversely affect our business, financial condition, results of operations and prospects. Although the UK is regarded as a
third country under the EU’s GDPR, the European Commission has now issued a decision recognizing the UK as providing adequate protection under the
EU  GDPR  and,  therefore,  transfers  of  personal  data  originating  in  the  EU  to  the  UK  remain  unrestricted.  Like  the  EU  GDPR,  the  UK  GDPR  restricts
personal  data  transfers  outside  the  UK  to  countries  not  regarded  by  the  UK  as  providing  adequate  protection.  The  UK  government  has  confirmed  that
personal data transfers from the UK to the EEA remain free flowing.

To enable the transfer of personal data outside of the EEA or the UK, adequate safeguards must be implemented in compliance with European and UK data
protection laws. On June 4, 2021, the EC issued new forms of standard contractual clauses for data transfers from controllers or processors in the EU/EEA
(or  otherwise  subject  to  the  GDPR)  to  controllers  or  processors  established  outside  the  EU/EEA  (and  not  subject  to  the  GDPR).  The  new  standard
contractual clauses replace the standard contractual clauses that were adopted previously under the EU Data Protection Directive. The UK is not subject to
the European Commission’s new standard contractual clauses but has published a draft version of a UK-specific transfer mechanism, which, once finalized,
will  enable  transfers  from  the  UK.  Following  a  ruling  from  the  Court  of  Justice  of  the  European  Union,  in  Data  Protection  Commissioner  v  Facebook
Ireland  Limited  and  Maximillian  Schrems  (‘Schrems  II’),  Case  C-311/18  (“Schrems  II”),  companies  relying  on  standard  contractual  clauses  to  govern
transfers of personal data to third countries (in particular the United States) will need to assess whether the data importer can ensure sufficient guarantees
for safeguarding the personal data under GDPR. This assessment includes assessing whether third party vendors can also ensure these guarantees. We will
be required to implement these new safeguards when conducting restricted data transfers under the EU and UK GDPR and doing so will require significant
effort and cost.

74

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. EU data protection authorities have the power to impose administrative fines for violations of the GDPR of up to a maximum of €20 million
or 4% of the data controller’s or data processor’s total worldwide global turnover for the preceding fiscal year, whichever is higher, and violations of the
GDPR  may  also  lead  to  damages  claims  by  data  controllers  and  data  subjects.  Such  penalties  are  in  addition  to  any  civil  litigation  claims  by  data
controllers, clients, and data subjects. As such, we will need to take steps to cause our processes to continue to be compliant with the applicable portions of
the GDPR, but we cannot assure you that we will be able to implement changes in a timely manner or without significant disruption to our business, or that
such steps will be effective, and we may face the risk of liability under the GDPR.

Similarly, non-compliance with the UK GDPR may result in monetary penalties of up to £17.5 million or 4% of worldwide revenue, whichever is higher.

Although the EU GDPR and the UK GDPR currently impose substantially similar obligations, it is possible that over time the UK GDPR could become
less aligned with the EU GDPR. This lack of clarity on future UK laws and regulations and their interaction with EU laws and regulations could add legal
risk, uncertainty, complexity and cost to our handling of EU personal information and our privacy and data security compliance programs and could require
us to implement different compliance measures for the UK and the European Union.

Many jurisdictions outside of Europe where we may do business or conduct trials in the future are also considering and/or have enacted comprehensive
data protection legislation. In addition, we also continue to see jurisdictions imposing data localization laws. These and similar regulations may interfere
with our intended business activities, inhibit our ability to expand into those markets, require modifications to our products or services or prohibit us from
continuing to offer services or conduct trials in those markets without significant additional costs.

Our employees, independent contractors, consultants, collaborators and CROs 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 CROs 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 actions could
have a significant impact on our business and results of operations, including the imposition of significant fines or other sanctions.

Global economic uncertainty and weakening product demand caused by political instability, changes in trade agreements and conflicts, such as the
conflict between Russia and Ukraine, could adversely affect our business and financial performance.

Economic uncertainty in various global markets caused by political instability and conflict and economic challenges caused by the COVID-19 pandemic
has resulted, and may continue to result, in weakened demand for our products. Political developments impacting government spending and international
trade,  including  potential  government  shutdowns  and  trade  disputes  and  tariffs,  may  negatively  impact  markets  and  cause  weaker  macro-economic
conditions.  The  effects  of  these  events  may  continue  due  to  potential  U.S.  government  shutdowns  and  the  transition  in  administrations,  and  the  United
States’  ongoing  trade  disputes  with  China  and  other  countries.  In  addition,  the  current  military  conflict  between  Russia  and  Ukraine  could  disrupt  or
otherwise adversely impact our operations and related sanctions, export controls or other actions that may be initiated by nations including the U.S., the
European Union or Russia (e.g., potential cyberattacks, disruption of energy flows, etc.) could adversely affect our business and/or our supply chain or
those of our third party service providers. The continuing effect of any or all of these events could adversely impact demand for our products, harm our
operations and weaken our financial results.

ITEM 1B. UNRESOLVED STAFF COMMENTS

We have no unresolved written comments regarding our 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.
Our research and development laboratory site is also located in Chicago and 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.

75

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 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. ("Xeris Pharma") when referring to periods prior to the acquisition of Strongbridge Biopharma plc, an Irish public limited company
("Strongbridge") (discussed below) on October 5, 2021 and to Xeris Biopharma Holdings, Inc. when referring to periods on or subsequent to October 5,
2021. Also, throughout this document, unless otherwise noted, references to Gvoke® include Gvoke PFS, Gvoke HypoPen® and Ogluo® (glucagon).

We  are  a  biopharmaceutical  company  committed  to  developing  and  commercializing  innovative  solutions  to  enhance  the  lives  of  people  with  life-

Acquisition of Strongbridge

On  May  24,  2021,  Xeris  Pharma  and  Strongbridge  entered  into  the  Transaction  Agreement  together  with  Xeris  Biopharma  Holdings,  Inc.,  a  Delaware
corporation  (“the  Company”),  and  Wells  MergerSub,  Inc.,  a  Delaware  corporation  (“MergerSub”)  (the  “Transaction  Agreement”)  whereby  we  would
acquire  Strongbridge  (the  “Acquisition”)  pursuant  to  a  scheme  of  arrangement  (the  “Scheme”)  under  Irish  law.  Under  the  terms  of  the  Transaction
Agreement, (i) the Company acquired Strongbridge by means of the Acquisition pursuant to the Scheme and (ii) MergerSub merged with and into Xeris
Pharma, with Xeris Pharma as the surviving corporation in the merger (the “Merger,” and the Merger together with the Acquisition, the “Transactions”). As
a  result  of  the  Transactions,  both  Xeris  Pharma  and  Strongbridge  became  wholly  owned  subsidiaries  of  the  Company.  the  Company  acquired  all  of  the
outstanding  Strongbridge  ordinary  shares  (“Strongbridge  Shares”)  in  exchange  for  (i)  0.7840  of  a  share  of  the  Company’s  common  stock  (“Company
Shares”) and cash in lieu of fractions of Company Shares due to a holder of Strongbridge Shares per Strongbridge Share and (ii) one (1) non-tradeable
contingent value right, worth up to a maximum of $1.00 per Strongbridge Share settleable in cash, additional Company Shares, or a combination of cash
and  additional  Company  Shares,  at  the  Company’s  sole  discretion.  On  October  5,  2021,  pursuant  to  the  Transaction  Agreement,  we  completed  the
Transactions.

Through the Acquisition, we added Keveyis (dichlorphenamide) to our commercial product portfolio. Keveyis is the first and only treatment approved by
FDA for hyperkalemic, hypokalemic, and related variants of primary periodic paralysis (“PPP”), a group of rare hereditary disorders that cause episodes of
muscle weakness or paralysis. In addition, we added a clinical-stage product candidate for rare endocrine diseases, Recorlev. Recorlev (levoketoconazole),
the  pure  2S,4R  enantiomer  of  the  enantiomeric  pair  comprising  ketoconazole,  is  a  next-generation  steroidogenesis  inhibitor  which  serves  as  a  chronic
therapy for adults with endogenous Cushing’s syndrome. Levoketoconazole has received orphan designation from the FDA and the European Medicines
Agency. Recorlev was acquired as an in-process research and development asset and subsequently approved by the FDA on December 30, 2021 for the
treatment of endogenous hypercortisolemia in adult patients with Cushing’s syndrome for whom surgery is not an option or has not been curative. Recorlev
was commercially launched in January 2022.

Patents

We  currently  own  141  patents  issued  globally,  including  a  composition  of  matter  patent  covering  our  ready-to-use  glucagon  formulation  that  expires  in
2036. Upon completion of the Transactions, Xeris Biopharma Holdings, Inc. controls the patents of Xeris Pharma and Strongbridge Dublin Limited, the
latter of which has 53 granted patents globally related to proprietary formulations of levoketoconazole (the active pharmaceutical ingredient in Recorlev)
and the uses of such formulations in treating certain endocrine-related diseases and syndromes. This includes US Patent No. 11,020,393, which was granted
on June 1, 2021, and which provides patent protection through 2040 for the use of Recorlev in the treatment of certain patients with persistent or recurrent
Cushing’s syndrome.

Financing

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  $253.0  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

77

 
stock, $86.3 million from our June 2020 Convertible Notes offering and $63.5 million from the Amended and Restated Loan and Security Agreement (as
amended, the "Amended Loan Agreement"), of which $20.0 million was repaid in June 2020.

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.  During  the  second  half  of  2020,  $39.1  million  in  principal  amount  of  Convertible  Notes  were  converted  into
13,171,791 shares of our common stock. As of December 31, 2021, 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, 2021, the outstanding balance under the Amended Loan Agreement was $43.5 million. As part of the Acquisition, we acquired
$38.5 million cash on October 5, 2021. On January 2, 2022, we entered into a securities purchase agreement in connection with a private placement (the
“Private  Placement”)  with  an  affiliate  of  Armistice  Capital,  LLC  (“Armistice”)  for  aggregate  gross  proceeds  of  approximately  $30.0  million.  The
transaction was completed on January 3, 2022.

In  March  2022,  Xeris  Biopharma,  Xeris  Pharma  and  certain  subsidiary  guarantors  of  the  Company  entered  into  a  Credit  Agreement  and  Guaranty  (the
"Hayfin Loan Agreement") with the lenders from time to time parties thereto (the “New Lenders”) and Hayfin Services LLP, as administrative agent for the
New Lenders, pursuant to which we and our subsidiaries party thereto granted a first priority security interest on substantially all of our assets, including
intellectual property, subject to certain exceptions. The Hayfin Loan Agreement provided for the New Lenders to extend $100.0 million in term loans (the
“Initial Loan”) to us on the closing date and up to an additional $50.0 million in delayed draw term loans during the one year period immediately following
the closing date (the “Delayed Draw Term Loans” and, together with the Initial Loan, the "Loans") in no more than three drawings of no less than $10.0
million per drawing subject to us being in pro forma compliance with the financial covenants and other conditions set forth therein. In conjunction with the
execution of the Hayfin Loan Agreement, the Amended Loan Agreement balance of $43.5 million was repaid in full and fees of $2.1 million in connection
with the loan repayment were paid. In addition to utilizing the proceeds to repay the obligations under the Amended Loan Agreement in full, the proceeds
will otherwise be used for general corporate purposes. After repayment, the Loans may not be re-borrowed.

For the years ended December 31, 2021 and 2020, we reported net losses of $122.7 million and $91.1 million, respectively. We have not been profitable
since inception, and, as of December 31, 2021, our accumulated deficit was $460.1 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, Keveyis and Recorlev;
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 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 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 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  and  product  candidates  to  our
patients and clinical trials respectively, 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 and product candidates.

We believe that customer demand for our products 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 were engaging with these customers remotely, via webinar programs and virtual meetings, as
we sought 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

78

in-person interactions. However, with the emergence of variants, some areas have implemented or reintroduced restrictions and may again in the future,
which may impact our sales and marketing personnel’s access to customers. Remote interactions generally are not as effective as in-person interactions. In
addition, several conferences and other programs at which we intended to market our products have been postponed, canceled and/or transitioned to virtual
meetings. We also have revised our Gvoke 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.

In addition to our sales and marketing personnel, we moved quickly to transition other employees to a remote work-from-home environment excluding
essential services, such as personnel in our laboratory. We have since reopened our offices on a voluntary basis and 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 $460.1 million at December 31, 2021. Although we believe that
our cash, cash equivalents, investments, and expected revenue from sales of Gvoke, Keveyis, and Recorlev 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 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, the emergence of variants and acceptance of vaccines, 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  and  a  registered
direct offering in March 2021 under which we raised gross proceeds of $27.0 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.

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 costs, 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

The following discussion sets forth certain components of our statement of operations of Xeris for years ended December 31, 2021 and 2020 as well as
factors that impact those items.

Product revenues, net

Product  revenues,  net,  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 make adjustments to
these allowances in the period in which the actual results or updates to estimates become known. See "Critical Accounting Policies and Use of Estimates
and Assumptions" for further information regarding the significant judgments and estimates involved in the determination of product revenues, net.

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 for Gvoke and Recorlev incurred 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

79

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;
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
advance our pipeline candidates and in particular 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 Gvoke and as we have concluded ongoing clinical programs and not yet initiated any
new  studies.  Based  on  FDA  interactions  and  expectations  for  a  registrational  program  to  support  a  mini-dose  indication  for  Glucagon  RTU  in  EIH,  we
submitted an IND in February 2022. We received FDA clearance in March 2022 and are actively planning to initiate a new phase 2 clinical program by the
end of 2022 to further address the management of EIH in people with diabetes who use insulin.

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, Keveyis and Recorlev in 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  and  complexity  as  a  public  reporting
company.

Other income (expense)

Other income (expense) consists primarily of interest expense related to our convertible debt and Amended Loan Agreement, 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,  2021,  we  had  $475.7  million  in
federal net operating loss carryforwards, $309.7 million of various state net operating loss carryforwards, $5.4 million in federal research and orphan drug
credits that begin to expire in 2025, and $2.5 million of state research and development credits that will begin to expire in 2022.

Product revenues, net were $49.3 million and $20.2 million for the years ended December 31, 2021 and 2020, respectively. The $29.1 million increase is
primarily due to an increase in demand and the acquisition of a new product, Keveyis.

Cost of goods sold

Cost of goods sold were $13.3 million and $9.3 million for the year ended December 31, 2021 and 2020, respectively. The increase of $4.0 million was
primarily made up of product cost on increased unit sales of $6.1 million, primarily offset by lower excess and obsolete expenses.

Research and development expenses

Research and development expenses increased $4.2 million for the year ended December 31, 2021 when compared to the year ended December 31, 2020.
The increase was primarily driven by higher pharmaceutical process development and clinical service costs across multiple programs of $4.3 million.

Selling, general and administrative expenses

Selling, general and administrative costs increased $52.0 million for the year ended December 31, 2021 when compared to the year ended December 31,
2020. Approximately $24.4 million of the increase related to the acquisition of Strongbridge, primarily including restructuring and related employee costs
of $11.0 million, transaction costs of $8.4 million and insurance costs of $3.5 million. In addition, we incurred $16.8 million of increased commercial-
related costs, including an increase to our sales force of $9.4 million and

81

 
increased commercial support for Gvoke, Keveyis and Recorlev of $7.4 million. The remaining change due to an increase in general expenses.

Other income (expense)

For the year ended December 31, 2021, interest and other income decreased $2.7 million in comparison to the year ended December 31, 2020, primarily
due to lower average balances in cash equivalents and investments and lower interest rates. Additionally, in 2020 other income included a legal settlement
of $1.5 million.

For the year ended December 31, 2021, interest expense decreased $3.5 million in comparison to the year ended December 31, 2020. The higher interest
expense in 2020 was primarily due to a loss on conversion of convertible debt of $2.6 million and a loss on extinguishment of debt of $0.7 million.

Liquidity and Capital Resources

Our primary uses of cash are to fund costs related to the manufacturing, marketing and selling of products, 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 provided 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. Additional
tranches of $15.0 million (the "Term B Loan") and $10.0 million (the “Term C Loan”) were contingent on achievement of certain revenue targets which
were not 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. 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  October  5,  2021,  the  acquisition  closing  date,  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. The shelf ceased to be accessible upon the consummation of
the Transactions. In January 2022, 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.

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 was also 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 our common stock. In
March 2021, we completed a registered direct offering of 6,553,398 shares of our common stock, the net proceeds of which were $26.9 million. As of
December  31,  2021,  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, 2021, the
outstanding balance under the Amended Loan Agreement was $43.5 million. On May 3, 2021, we entered into a fifth amendment to the Amended Loan
Agreement  which  provides  that  if  we  achieve  a  certain  revenue  milestone  prior  to  November  30,  2021,  then  the  period  for  interest-only  payments  is
extended six months to July 2022 and the term loan will be payable in 24 equal monthly installments. If we achieve another revenue milestone prior to May
31, 2022, the period for interest-only payments is further extended three months to October 2022 and the term loan will be payable in 21 equal monthly
installments. If we achieve a third revenue milestone by August 31, 2022, the period for interest-only payments is further extended three months, to January
2023 and the term loan will be payable in 18 equal monthly installments. We achieved all revenue milestones and therefore classified the amounts due
under  the  Amended  Loan  Agreement  as  non-current  on  our  balance  sheet  as  of  December  31,  2021.  On  January  2,  2022,  we  entered  into  a  securities
purchase agreement in connection with the Private Placement with Armistice for aggregate gross proceeds of approximately $30.0 million and completed
the transaction on January 3, 2022.

In  March  2022,  Xeris  Biopharma,  Xeris  Pharma  and  certain  subsidiary  guarantors  of  the  Company  entered  into  a  Credit  Agreement  and  Guaranty  (the
"Hayfin Loan Agreement") with the lenders from time to time parties thereto (the “New Lenders”) and Hayfin Services LLP, as administrative agent for the
New Lenders, pursuant to which we and our subsidiaries party thereto granted a first priority security interest on substantially all of our assets, including
intellectual property, subject to certain exceptions. The Hayfin Loan Agreement provided for the New Lenders to extend $100.0 million in term loans (the
“Initial Loan”) to us on the closing date and up to an additional $50.0 million in delayed draw term loans during the one year period immediately following
the closing date (the “Delayed Draw Term Loans” and, together with the Initial Loan, the "Loans") in no more than three drawings of no less than

82

$10.0 million per drawing subject to us being in pro forma compliance with the financial covenants and other conditions set forth therein. In conjunction
with the execution of the Hayfin Loan Agreement, the Amended Loan Agreement balance of $43.5 million was repaid in full and fees of $2.1 million in
connection with the loan repayment were paid. In addition to utilizing the proceeds to repay the obligations under the Amended Loan Agreement in full, the
proceeds will otherwise be used for general corporate purposes. After repayment, the Loans may not be re-borrowed.

Capital Resources and Funding Requirements

We  have  incurred  operating  losses  since  inception,  and  we  have  an  accumulated  deficit  of  $460.1  million  at  December  31,  2021.  Based  on  our  current
operating  plans  and  existing  working  capital  at  December  31,  2021,  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 additional expenditures in the near term to support the marketing
and selling of Gvoke, Keveyis and Recorlev as well as 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  marketing  and  selling  of  Gvoke,  Keveyis  and  Recorlev,  as  well  as  our  product  development  and  clinical
operations, including completion of future clinical trials, will depend on the amount and timing of cash received from product revenue and potential future
financings. Our future capital requirements will depend on many factors, including:

<

<
<
<
<
<

the successful integration of the Acquisition and achievement of expected revenue and synergies
the costs of commercialization activities, including product marketing, sales and distribution;
our degree of success in commercializing Gvoke, Keveyis and Recorlev;
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.

We may not be able to successfully integrate and combine the businesses of Xeris and Strongbridge following the completion of the Transactions and we
may not realize the anticipated benefits from the Transactions. Also, as we continue the marketing and selling of Gvoke, Keveyis and Recorlev, 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, Keveyis and Recorlev. 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.

Net cash used in operating activities was $95.5 million for the year ended December 31, 2021, compared to $80.6 million for the year ended December 31,
2020. The increase in net cash used in operating activities was primarily driven by a change in working capital and an increase in net losses due to higher
personnel related costs from increased headcount, one-time transaction cost of Strongbridge acquisition and related restructuring costs. For a discussion
regarding  product  revenues,  net  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."

Investing activities

Net cash provided by investing activities was $98.0 million for the year ended December 31, 2021, compared to net cash used in investing activities of
$27.4 million for the year ended December 31, 2020. The increase in cash provided by investing activities was

83

 
primarily due to a greater number of investments maturing or being sold and invested in cash equivalents to fund operations, as well as $38.5 million of
cash acquired from the acquisition of Strongbridge.

Financing activities

Net  cash  provided  by  financing  activities  was  $27.2  million  for  the  year  ended  December  31,  2021,  compared  to  $126.1  million  for  the  year  ended
December 31, 2020. The decrease was primarily due to the net proceeds of $26.9 million from the March 2021 registered direct offering of our common
stock, as compared to the net proceeds of $81.2 million from the convertible debt offering and $3.5 million from the drawdown on the senior loan, $61.5
million from equity offerings of our common stock, partially offset by the $20.0 million pay down of principal on the senior loan.

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  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, Revenue Recognition, to all contracts with customers within the scope of the standard.

We sell product primarily to wholesalers or a specialty pharmacy who subsequently resell to retail pharmacies or patients. 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, Keveyis and Recorlev in the United States only and Ogulo (European brand name of Gvoke) in
the United Kingdom.

Revenue is recognized when our customer (e.g., a wholesaler or specialty pharmacy) 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 we expect to receive in exchange for those goods or
services.

Revenues  are  recorded  at  the  net  product  sales  price,  which  includes  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.  The  Company  applies  significant  judgments  and  estimates  in  determining  some  of  these  allowances.  If  actual  results  differ  from  its
estimates, adjustments are made to these allowances in the period in which the actual results or updates to estimates become known.

    Patient Copay Assistance Program

We  offer  savings  programs  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
estimated  levels  of  inventory  in  the  distribution  channel. Accrued  copay  fees  are  recorded  as  a  reduction  of  product  revenues  and  included  in
accrued trade discounts and rebates on the consolidated balance sheets.

Commercial Rebates

We  contract  with  certain  private  payor  organizations,  primarily  insurance  companies  and  pharmacy  benefit  managers,  to  provide  rebates  with
respect to utilization of the products and contracted formulary status. We accrue estimated rebates based on actual average rebate amounts and
estimated  percent  of  product  that  will  be  prescribed  to  qualified  patients  and  records  the  rebate  as  a  reduction  of  product  revenues.  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 and discounts based on actual average rebate amounts and estimated percent
of product that will be prescribed to qualified patients and records the rebates as a reduction of product revenues. Accrued government rebates are
included in accrued trade discounts and rebates on the consolidated balance sheets.

84

Chargebacks

We arrange with certain commercial and government entities allowing them to buy 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 list price and the
discounted price back to us. We accrue 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 product revenues. Accrued chargebacks
are recorded as an allowance against trade receivables on the consolidated balance sheets.

    Product Returns

For some products, our customers generally have the right to return product during the period beginning six months prior to the product expiration
date and up to one year after the product expiration date. We do not have extensive history of product returns and uses various factors to estimate
the  provision  for  returns,  including  the  launch  date  of  products,  third-party  industry  data  for  comparable  products  in  the  market  and  estimated
channel inventory data. 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  it  were  to  increase  or  decrease  the  rate  by  1%,  it  would  have  a  $0.6  million  impact  on  revenue  in  the  year  ended
December  31,  2021.  We  record  estimated  product  returns  in  accrued  returns  reserve  on  the  consolidated  balance  sheets  and  as  a  reduction  of
product revenues.

Business combinations

We account for business combinations using the acquisition method of accounting in accordance with ASC 805, Business Combinations. Identifiable assets
acquired and liabilities assumed are recorded at their acquisition date fair values. The excess of the fair value of purchase consideration over the fair values
of  the  identifiable  assets  and  liabilities  is  recorded  as  goodwill.  Acquisition  related  costs  are  expensed  as  incurred.  Upon  acquisition,  the  accounts  and
results of operations are consolidated as of and subsequent to the acquisition date.

When  determining  the  fair  values  of  assets  acquired  and  liabilities  assumed,  we  make  significant  estimates  and  assumptions,  especially  with  respect  to
intangible assets. We utilize commonly accepted valuation techniques, such as the income approach in establishing the fair value of intangible assets.

Contingent considerations

The fair value of the CVRs was calculated by using a discounted cash flow method for the Keveyis patent milestone and an option pricing method for the
Recorlev and Keveyis sales milestones. In the case of Keveyis milestones, we applied a scenario-based method and weighted them based on the possible
achievement  of  each  milestone.  This  fair  value  measurement  is  based  on  significant  inputs  not  observable  in  the  market  and  thus  represents  a  Level  3
measurement as defined in ASC 820. This value is then remeasured for future expected payout as well as the increase in fair value due to the time value of
money. These gains or losses, if any, are included as a component of operating cash flows.

Warrants

Some  of  our  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. Upon completion of the Acquisition, each outstanding and unexercised Strongbridge private placement warrant was assumed by the Company such
that  the  applicable  holders  will  have  the  right  to  subscribe  for  the  Company's  Shares,  in  accordance  with  certain  terms  of  the  Strongbridge  private
placement warrants. Pursuant to the terms of the warrant agreement, we could be required to settle the warrants in cash and, as a result, the warrants are
required to be measured at fair value and reported as a liability in the consolidated balance sheet. We recorded the fair value of the warrants upon issuance
using the Black-Scholes Model and are required to revalue the warrants at each reporting date with any changes in fair value recorded on the statement of
operations.

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

86

 
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, 2021 would increase or decrease interest income by approximately $1.0 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, 2021, 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, 2021 was 0.10%, 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, 2021, 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, 2021.

Report of Independent Registered Public Accounting Firm

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

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Xeris Biopharma Holdings, Inc. and subsidiaries (the Company) as of December 31,
2021 and 2020, 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,  2021,  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, 2021 and 2020, and the results of its
operations and its cash flows for each of the years in the two‑year period ended December 31, 2021, 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.

Notes to Consolidated Financial Statements

Note 1. Organization and nature of the business

Nature of business

Xeris Biopharma Holdings, Inc. ("Xeris Biopharma" or the "Company") is a biopharmaceutical company committed to developing and commercializing
innovative solutions to enhance the lives of people with life-threatening diseases. The Company's primary focus is on therapies for patient populations in
endocrinology, neurology, and gastroenterology. The Company currently has three commercially available products, Gvoke, a ready-to-use liquid glucagon
for the treatment of severe hypoglycemia, Keveyis, the first and only U.S. Food and Drug Administration (“FDA”) approved therapy for primary periodic
paralysis  (“PPP”),  and  Recorlev,  approved  by  the  FDA  in  December  2021  for  the  treatment  of  endogenous  hypercortisolemia  in  adult  patients  with
Cushing’s Syndrome. The Company also has a pipeline of development programs to extend the current marketed products into new indications and uses or
bring new products forward using the proprietary formulation technology platforms, XeriSol

 and XeriJect

TM
.

TM

On October 5, 2021, Xeris Pharmaceuticals, Inc. ("Xeris Pharma") acquired Strongbridge Biopharma plc (“Strongbridge”), a biopharmaceutical company
commercializing  therapies  for  rare  diseases  with  significant  unmet  needs.  Immediately  following  the  acquisition  and  related  transactions,  both  Xeris
Pharma  and  Strongbridge  became  wholly  owned  subsidiaries  of  Xeris  Biopharma.  The  common  stock  of  Xeris  Pharma  and  the  ordinary  shares  of
Strongbridge were de-registered after completion of the Transactions. On October 6, 2021, Xeris Biopharma’s common stock, par value $0.0001 per share,
commenced trading on the Nasdaq Global Select Market (“Nasdaq”) under the ticker symbol “XERS”. See “Note 3 – Business combination” for a more
detailed description of the acquisition.

As used herein, the “Company” or "Xeris" refers to Xeris Pharma when referring to periods prior to the acquisition of Strongbridge, an Irish public limited
company, on October 5, 2021 and to Xeris Biopharma when referring to periods on or subsequent to October 5, 2021. As a result, Xeris Pharma became the
predecessor to Xeris Biopharma Holdings, Inc. upon completion of the Merger on October 5, 2021.

Liquidity and capital resources

The  Company  has  incurred  operating  losses  since  inception  and  has  an  accumulated  deficit  of  $460.1  million  as  of  December  31,  2021.  The  Company
expects to continue to incur net losses for at least the next 12 months beyond the issuance date of these consolidated financials. Based on the Company’s
current operating plans, existing working capital at December 31, 2021, and capital raised after year-end (refer to Note 19), the Company believes the cash
resources  are  sufficient  to  sustain  operations  and  capital  expenditure  requirements  for  at  least  the  next  12  months  from  the  issuance  date  of  these
consolidated financial statements. If needed, the Company may elect to finance the operations through equity or debt financing along with revenues.

There  can  be  no  assurance  that  such  funding  may  be  available  to  the  Company  on  acceptable  terms,  or  at  all,  or  that  the  Company  will  be  able  to
successfully market and sell Gvoke, Keveyis and Recorlev. Market volatility resulting from the COVID-19 pandemic or other factors could also adversely
impact the Company's ability to access capital as and when needed. The issuance of equity securities may result in dilution to stockholders. If the Company
raises  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  the  operations.  The  failure  to  raise  funds  as  and  when  needed  could  have  a
negative impact on the Company's financial condition and ability to pursue the business strategies. If additional funding is not secured when required, the
Company may need to delay or curtail the operations until such funding is received, which would have a material adverse impact on the business prospects
and results of operations.

Significant risks

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  available  products  and  any  future  products,  if  and  when  approved,  successful  development  of  the  product
candidates, the development of new technological innovations by competitors, and protection of intellectual property.

The ongoing global outbreak of the 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 the business practices (including remote work for most of the employees from time to time).
While the Company cannot predict the scope and severity, these developments and measures could materially and adversely affect the business, results of
operations and financial condition. The Company is continuing to closely monitor the impact of the COVID-19 pandemic on all aspects of the business and
is taking steps to minimize the impact on the business. However, the extent to which COVID-19 impacts the 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  the  Company  or  any  of  the  third  parties  with  whom  the
Company engages were to experience shutdowns or other business disruptions, the Company's ability to conduct the

94

XERIS BIOPHARMA HOLDINGS, INC.

Notes to Consolidated Financial Statements

business in the manner and on the timelines presently planned could be materially or negatively affected, which could have a material adverse impact on
the business, results of operations and financial condition.

Note 2. Basis of presentation and summary of significant accounting policies and estimates

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, 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 Biopharma Holdings, Inc. and subsidiaries. All intercompany transactions
have been eliminated.

Reclassification

As a result of the acquisition, certain reclassifications of prior period amounts have been made to improve comparability and conform to the current period
presentation. Presentation changes were made to the Consolidated Statements of Operations and Comprehensive Loss. In addition, certain reclassifications
of prior period data have been made in the Notes to Consolidated Financial Statements to conform to the current period presentation.

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, Revenue Recognition, to all contracts with customers within the scope of the standard.

The Company sells product primarily to wholesalers or a specialty pharmacy who subsequently resell to retail pharmacies or patients. 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, Keveyis and Recorlev in the United States only
and Ogulo (European brand name of Gvoke) in the United Kingdom.

Revenue is recognized when the Company's customer (e.g., a wholesaler or specialty pharmacy) obtains control of promised goods or services, which is
when the Company's 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.

Revenues  are  recorded  at  the  net  product  sales  price,  which  includes  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.  The  Company  applies  significant  judgments  and  estimates  in  determining  some  of  these  allowances.  If  actual  results  differ  from  its
estimates, adjustments are made to these allowances in the period in which the actual results or updates to estimates become known.

    Patient Copay Assistance Program

The  Company  offers  savings  programs  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 product revenues and included in accrued trade discounts and rebates on the consolidated balance sheets.

Commercial Rebates

95

XERIS BIOPHARMA HOLDINGS, INC.

Notes to Consolidated Financial Statements

The  Company  contracts  with  certain  private  payor  organizations,  primarily  insurance  companies  and  pharmacy  benefit  managers,  to  provide
rebates with respect to utilization of the products and contracted formulary status. The Company accrues estimated rebates based on actual average
rebate  amounts  and  estimated  percent  of  product  that  will  be  prescribed  to  qualified  patients  and  records  the  rebate  as  a  reduction  of  product
revenues. 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 actual average rebate amounts
and estimated percent of product that will be prescribed to qualified patients and records the rebates as a reduction of product revenues. Accrued
government rebates are included in accrued trade discounts and rebates on the consolidated balance sheets.

Chargebacks

The  Company  arranges  with  certain  commercial  and  government  entities  allowing  them  to  buy  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 list
price 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
product revenues. Accrued chargebacks are recorded as an allowance against trade receivables on the consolidated balance sheets.

    Product Returns

For  some  products,  the  Company's  customers  generally  have  the  right  to  return  product  during  the  period  beginning  six  months  prior  to  the
product expiration date and up to one year after the product expiration date. The Company does not have extensive history of product returns and
uses various factors to estimate the provision for returns, including the launch date of products, third-party industry data for comparable products
in the market and estimated channel inventory data. 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 the 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
$0.6 million impact on revenue in the year ended December 31, 2021. The Company records estimated product returns in accrued returns reserve
on the consolidated balance sheets and as a reduction of product revenues.

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,  the  Company  accrues  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 product revenues.

Service Fees

The Company records service fees paid to the wholesaler and specialty pharmacy customers for distribution and inventory management services
as a reduction to product revenues. 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.

Concentration of credit risk

For the years ended December 31, 2021 and 2020, four customers accounted for 95% and 92% of the Company’s gross product revenues, respectively. The
same four customers accounted for 99% and 98% of the trade accounts receivable, net at December 31, 2021 and December 31, 2020, respectively.

96

XERIS BIOPHARMA HOLDINGS, INC.

Notes to Consolidated Financial Statements

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  contract
manufacturing organizations, and manufacturing overhead costs, including 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 and Recorlev incurred prior to
approval and initial commercialization were expensed as research and development expenses.

The Company does not incur material cost of goods sold related to royalty, contract and other revenue.

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 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 the 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, 2021 and 2020, the Company did not accrue any interest or penalties on uncertain
tax positions.

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 as cash equivalents.

Investments

The Company classifies 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.

97

XERIS BIOPHARMA HOLDINGS, INC.

Notes to Consolidated Financial Statements

Inventory

Inventory is stated at the lower of cost or net realizable value, using the first-in, first-out convention. Inventory consists 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  inventory  includes  the  direct  purchase  cost  of  materials  and  supplies,  charges  from  contract  manufacturing  organizations  and
manufacturing overhead costs. The Company reviews inventory to assess if there is obsolete or excess inventory and records a charge to cost of goods sold
if and when applicable.

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  long-lived  assets  for  potential  impairment  in  accordance  with  ASC  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 impairment charges for the years ended December 31, 2021 and 2020, respectively.

Business combinations

The  Company  accounts  for  business  combinations  using  the  acquisition  method  of  accounting  in  accordance  with  ASC  805,  Business  Combinations.
Identifiable assets acquired and liabilities assumed are recorded at their acquisition date fair values. The excess of the fair value of purchase consideration
over the fair values of the identifiable assets and liabilities is recorded as goodwill. Acquisition related costs are expensed as incurred. Upon acquisition, the
accounts and results of operations are consolidated as of and subsequent to the acquisition date.

When  determining  the  fair  values  of  assets  acquired  and  liabilities  assumed,  management  makes  significant  estimates  and  assumptions,  especially  with
respect to intangible assets. The Company utilizes commonly accepted valuation techniques, such as the income approach in establishing the fair value of
intangible assets. See “Note 3 – Business combination” for additional detail.

Goodwill

The Company tests goodwill for impairment on an annual basis or whenever events occur that may indicate possible impairment. Goodwill is recorded as
the  difference,  if  any,  between  the  aggregate  consideration  paid  for  an  acquisition  and  the  fair  value  of  the  net  tangible  and  identified  intangible  assets
acquired under a business combination. Goodwill is reviewed for impairment at a reporting unit level annually in the fourth quarter, or more frequently if
events or circumstances indicate that the goodwill might be impaired. The Company first assesses qualitative factors to determine whether it is necessary to
perform the quantitative goodwill impairment test. If, after assessing the totality of events or circumstances, the Company determines that it is not more
likely than not that the fair value of the net assets is less than their carrying amount, then the quantitative goodwill impairment test is unnecessary.

If, based on the qualitative assessment, it is determined that it is more likely than not that the fair value of the net assets is less than their carrying amount,
then the Company proceeds to perform the quantitative goodwill impairment test. In connection with the annual impairment test conducted in the fourth
quarter of 2021, after the acquisition was completed, the Company performed a qualitative assessment in connection with the annual goodwill impairment
evaluation and determined that it was more likely than not that the fair value of the net assets exceeded their carrying value.

Intangible assets

Acquired definite life intangible assets are amortized using the straight-line method over their respective estimated useful lives. The Company evaluates the
potential impairment of intangible assets if events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable
or that the useful lives of these assets are no longer appropriate.

For further discussion of identified intangible assets, see “Note 7 – Intangible assets”.

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, reduce the carrying value of the related debt.

Contingent considerations

The fair value of the Contingent Value Rights (“CVRs") is calculated by using a discounted cash flow method for the Keveyis patent milestone and an
option pricing method for the Recorlev and Keveyis sales milestones. In the case of Keveyis milestones, the Company applies a scenario-based method and
weighted them based on the possible achievement of the milestone. This fair value measurement is based on significant inputs not observable in the market
and thus represents a Level 3 measurement as defined in ASC 820, Fair Value Measurement. The key assumptions used include the discount rate and sales
growth.  The  estimated  value  of  the  CVR  consideration  is  preliminary  only  and  is  based  upon  available  information  and  certain  assumptions  which  the
Company's management believes are reasonable under the circumstances. The ultimate payout under the CVRs may differ materially from the assumptions
used in determining the fair value of the CVR consideration. This value is then remeasured for future expected payout as well as the increase in fair value
due to the time value of money. These gains or losses, if any, are recognized in the consolidated statements of operations and comprehensive loss.

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 provide for tenant improvement allowances whereby
the  landlord  funded  the  cost  to  build  out  the  space.  The  Company  records  a  liability  for  such  lease  incentives  which  is  amortized  to  rent  expense  on  a
straight-line basis throughout the lease term.

Warrant liability

Warrants required to be settled in cash are accounted for as liabilities in accordance with ASC 480, Distinguishing Liabilities from Equity. The fair value of
these warrants are remeasured each reporting period using the Black-Scholes option-pricing model 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  liability  is  recorded  in  other  current  liabilities  on  the
consolidated  balance  sheet.  Generally,  changes  in  the  fair  value  of  the  warrant  liabilities  are  recorded  in  the  consolidated  statement  of  operations  and
comprehensive loss.

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 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, warrants and CVRs.

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.

New accounting pronouncements

Recently issued accounting pronouncements

In  October  2021,  the  FASB  issued  ASU  2021-08,  Business  Combinations  (Topic  805):  Accounting  for  Contract  Assets  and  Contract  Liabilities  from
Contracts  with  Customers.  This  update  requires  that  an  acquirer  recognize  and  measure  contract  assets  and  contract  liabilities  acquired  in  a  business
combination in accordance with Topic 606, Revenue from Contracts with Customers. This standard requires that an acquirer recognize and measure such
contract assets and contract liabilities under Topic 606, Revenue from Contracts with Customers, as if it had originated the contracts. This standard also
allows for election of certain practical expedients, which are applied on an acquisition-by-acquisition basis. This standard is effective for the Company for
fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, including for any interim
period, and if elected, this standard is applied retrospectively for any acquisitions that occurred in the fiscal year of interim adoption. Since the Company
already adopted ASC 2014-09, Revenue from Contracts with Customers (Topic 606), which provides a single comprehensive accounting model on revenue
recognition  for  contracts  with  customers,  the  Company  elected  to  early  adopt  ASU  2021-08  in  the  fourth  quarter  2021  as  the  Company  completed  the
acquisition of Strongbridge. Therefore, the Company has accounted for the acquisition of all contracts with customers from the Strongbridge acquisition in
accordance with ASC 606. Under previous U.S. GAAP, the Company would have discounted the acquired contracts with customers to present value as of
the acquisition closing date.

In  May  2021,  the  FASB  issued  ASU  No.  2021-04,  Earnings  Per  Share  (Topic  260),  Debt-Modifications  and  Extinguishments  (Subtopic  470-50),
Compensation-Stock  Compensation  (Topic  718),  and  Derivatives  and  Hedging-Contracts  in  Entity’s  Own  Equity  (Subtopic  815-40).  This  standard
addresses issuer’s accounting for certain modifications or exchanges of freestanding equity-classified written call options. This standard is effective for all
entities, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted. The Company
does not currently expect the adoption of this new standard to have a material impact on the financial statements.

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 is effective for the Company for fiscal years 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 the 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
London Inter-bank Offered Rate (“LIBOR”) or other reference rates that are expected to be discontinued because of reference rate reform. This standard is
effective for all entities as of March 12, 2020 through December 31, 2022. The Company does not currently expect the adoption of this new standard to
have a material impact on the 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 intra-period 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.  Early  adoption  of  this
standard is permitted. The Company does not currently expect the adoption of this new standard to have a material impact on the financial statements.

In  January  2017,  the  FASB  issued  ASU  2017-04,  Intangibles  –  Goodwill  and  Other  (Topic  350):  Simplifying  the  Test  for  Goodwill  Impairment.  The
standard  simplifies  the  subsequent  measurement  of  goodwill  by  eliminating  Step  2  from  the  goodwill  impairment  test.  Under  the  new  standard,  the
Company is required to perform its annual or interim goodwill impairment test by comparing the fair value of the reporting unit with its carrying amount,
and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The guidance is effective for the
Company for fiscal years beginning after December 15, 2022, including interim periods within that annual period, with early adoption permitted. Since the
Company started to have goodwill after the business combination in the fourth quarter 2021, the Company early adopted this guidance prospectively on
January 1, 2021, and it did not have any impact on the Company’s consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.
This standard requires entities to estimate an expected lifetime credit loss on financial assets ranging from

100

XERIS BIOPHARMA HOLDINGS, INC.

Notes to Consolidated Financial Statements

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 is effective for the Company for fiscal years beginning after December 15, 2020, and interim
periods within fiscal years beginning after December 15, 2021. On November 15, 2019, the FASB delayed the effective date of FASB ASC Topic 326 for
certain small public companies and other private companies. As amended, the effective date of ASC Topic 326 was delayed until fiscal years beginning
after December 15, 2022 for SEC filers that are eligible to be smaller reporting companies under the SEC’s definition, as well as private companies and
not-for-profit entities. The Company is currently evaluating the impact the adoption of this new standard will have on the financial statements.

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. This standard is effective for the Company
for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. The FASB has recently
extended the effective date of this standard for certain companies. As amended in ASU 2020-05, 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 the balance sheet.

Note 3. Business combination

On May 24, 2021, Xeris Pharma issued an announcement pursuant to Rule 2.5 of the Irish Takeover Panel Act 1997 (as amended), Takeover Rules, 2013,
disclosing that the boards of directors of Xeris Pharma and Strongbridge (with the exception of Jeffrey W. Sherman, M.D., a director in common to both
companies,  who  abstained  from  the  voting),  had  reached  agreement  on  the  terms  of  a  recommended  acquisition  of  Strongbridge  by  Xeris  Pharma  (the
“Acquisition”).  Xeris  Pharma,  Strongbridge,  Xeris  Biopharma  and  Wells  MergerSub,  Inc.,  a  Delaware  corporation  (“MergerSub”),  entered  into  a
Transaction Agreement, dated as of May 24, 2021 (the “Transaction Agreement”).

On  October  5,  2021  (the  "acquisition  closing  date"),  pursuant  to  the  Transaction  Agreement,  Xeris  Pharma  completed  the  acquisition  of  Strongbridge.
Upon  completion  of  the  Acquisition,  (a)  the  Company  acquired  Strongbridge  by  means  of  a  scheme  of  arrangement  (the  “Scheme”)  under  Irish  law
pursuant to which the Company acquired all of the outstanding ordinary shares of Strongbridge (“Strongbridge Shares”) in exchange for (i) 0.7840 of a
share of the Company’s common stock (“Company Shares”) and cash in lieu of fractions of Company Shares in exchange for each Strongbridge Share held
by  such  Strongbridge  Shareholders  and  (ii)  one  (1)  non-tradeable  CVR,  worth  up  to  a  maximum  of  $1.00  per  Strongbridge  Share  settleable  in  cash,
additional Company Shares, or a combination of cash and additional Company Shares, at the Company’s sole election and (b) MergerSub merged with and
into  Xeris  Pharma,  with  Xeris  Pharma,  as  the  surviving  corporation  in  the  merger  (the  “Merger,”  and  the  Merger  together  with  the  Acquisition,  the
“Transactions”).

Upon completion of the Merger, (a) each share of Xeris Pharma common stock was assumed by the Company and converted into the right to receive one
Company Share and any cash in lieu of fractional entitlements due to a Xeris Pharma shareholder and (b) each Xeris Pharma option, stock appreciation
right,  restricted  share  award  and  other  Xeris  Pharma  share  based  award  that  was  outstanding  was  assumed  by  the  Company  and  converted  into  an
equivalent equity award of the Company, which award was subject to the same number of shares and the same terms and conditions as were applicable to
the Xeris Pharma award in respect of which it was issued. On October 6, 2021, the Company’s common stock, par value $0.0001 per share, commenced
trading on the Nasdaq Global Select Market (“Nasdaq”) under the ticker symbol “XERS”.

At the effective time of the Scheme, Strongbridge’s outstanding equity awards were treated as set forth in the Transaction Agreement, such that (i) each
Strongbridge Share Award was vested and settled for Strongbridge Shares immediately prior to the effective time of the Scheme, (ii) each Strongbridge
Option became fully vested and exercisable immediately prior to the effective time of the Scheme, (iii) each unexercised Strongbridge Option was assumed
by the Company and converted into an option to purchase Company Shares (each, a “Strongbridge Rollover Option”), with the exercise price per Company
Share and the number of Company Shares underlying the Strongbridge Rollover Option adjusted to reflect the conversion from Strongbridge Shares into
Company Shares, provided that each Strongbridge Rollover Option will continue to have, and be subject to, the same terms and conditions that applied to
the corresponding Strongbridge Rollover Option (except for terms rendered inoperative by reason of the Acquisition or for immaterial

101

Notes to Consolidated Financial Statements

administrative or ministerial changes that are not adverse to any holder other than in any de minimis respect), provided that the terms of each Strongbridge
Rollover Option with an exercise price of $4.50 or less (prior to the adjustment described above) were amended to provide that it shall remain exercisable
for a period of time following the effective time of the Scheme equal to the lesser of (A) the maximum remaining term of such corresponding Strongbridge
Option  and  (B)  the  fourth  anniversary  of  the  effective  date  of  the  Merger,  in  each  case  regardless  of  whether  the  holder  of  such  Strongbridge  Rollover
Option experiences a termination of employment or service on or following the effective time of the Scheme and (iv) the Company issued to each holder of
a Strongbridge Rollover Option one CVR with respect to each Strongbridge Share subject to the applicable Strongbridge Option, provided that in no event
shall such holder be entitled to any payments with respect to such CVR unless the corresponding Strongbridge Option has been exercised on or prior to any
such payment.

Additionally,  on  completion  of  the  Acquisition,  (a)  each  outstanding  and  unexercised  Strongbridge  warrant  (except  private  placement  warrants)  was
assumed by the Company such that, upon exercise, the applicable holders will have the right to have delivered to them the reference property (as such term
is defined in the Strongbridge assumed warrants) and (b) each outstanding and unexercised Strongbridge private placement warrant was assumed by the
Company such that the applicable holders will have the right to subscribe for Company Shares, in accordance with certain terms of the Strongbridge private
placement warrants.

The  Acquisition  was  accounted  for  as  a  business  combination  using  the  acquisition  method  of  accounting  under  the  provisions  of  ASC  805,  Business
Combinations.

The Acquisition will diversify and increase the Company’s revenue base into the specialized commercial platforms and expand the development pipeline.
Additionally,  the  Company  expects  to  achieve  significant  synergies  by  eliminating  redundant  processes  and  headcount,  most  notably  within  the
commercial, executive and general and administrative functions.

Acquisition consideration

The acquisition-date fair value of the consideration transferred totaled $169.1 million, which consisted of the following:

Fair value of consideration transferred (in thousands, except share number)

Xeris Biopharma Holdings, Inc. common shares (58,082,606 shares)

The Company’s acquisition accounting is primarily pending final valuation and potential CVR fair value adjustments to the consideration. The fair value of
the common stock issued was determined based on the closing market price of shares of the Company’s common stock on the acquisition date.

The  fair  value  of  the  private  placement  warrants  was  determined  using  the  Black-Scholes  valuation  model  which  considers  the  expected  terms  of  the
private placement warrants from the acquisition closing date as well as the risk-free interest rate, current exercise price of $2.50 multiplied by (the average
of Xeris Pharma closing prices for the 20-day period ending three trading days prior to acquisition closing date/the average of Strongbridge closing prices
for the 20-day period ending three trading days prior to acquisition closing date) and a volatility of 50%.

The CVRs represent contingent additional consideration of up to $1.00 for each CVR, payable to CVR holders, to satisfy future performance milestones,
settleable  in  cash,  common  stock,  or  a  combination  of  cash  and  common  stock,  at  the  Company's  sole  election.  The  CVRs  are  conditioned  upon  the
achievement of the following:

• Keveyis Milestone: $0.25 per CVR, upon the earlier of the first listing of any patent in the FDA's Orange Book for Keveyis by the end of 2023 or

the first achievement of at least $40 million in net sales of Keveyis in 2023;

•

•

2023 Recorlev Milestone: $0.25 per CVR, upon the first achievement of at least $40 million in net sales of Recorlev in 2023; and

2024 Recorlev Milestone: $0.50 per CVR, upon the first achievement of at least $80 million in net sales of Recorlev in 2024.

Refer to "Note 12 - Fair Value Measurements", for information related to the fair value measurements on CVRs and valuation methods utilized.

102

XERIS BIOPHARMA HOLDINGS, INC.

Notes to Consolidated Financial Statements

As of the acquisition closing date, there were approximately 74.1 million CVRs. There will be additional issuance of up to 10.5 million. CVRs to holders of
Strongbridge rollover options and assumed warrants upon exercise.

Preliminary purchase price allocation

In accordance with ASC 805, Xeris Pharma was determined to be the accounting acquirer in the Acquisition. The Company has applied the acquisition
method of accounting that requires, among other things, that identifiable assets acquired and liabilities assumed generally be recognized on the balance
sheet at fair value as of the acquisition date. In determining the fair value, the Company utilized various forms of the income, cost and market approaches
depending on the asset or liability being fair valued. The estimation of fair value required significant judgment related to future net cash flows (including
revenue,  operating  expenses,  and  working  capital),  discount  rates  reflecting  the  risk  inherent  in  each  cash  flow  stream,  competitive  trends,  market
comparables and other factors. Inputs were generally determined by taking into account historical data (supplemented by current and anticipated market
conditions), trends and growth rates.

The  initial  allocation  of  the  purchase  price  was  based  on  preliminary  valuations  and  assumptions.  During  the  fourth  quarter  of  2021,  the  Company  did
record $4.9 million of net deferred tax liabilities based on jurisdictional outcomes. Otherwise, there were no material measurement period adjustments.

The table below presents the estimated fair value that was allocated to Strongbridge’s assets and liabilities based upon fair values as determined by the
Company (in thousands):

The above allocation of the purchase price is provisional and is still subject to change within the measurement period (up to one year from the acquisition
date) as a result of additional information obtained with regards to facts and circumstances that existed as of the acquisition date. The final allocation of the
purchase price is expected to be completed as soon as practicable, but no later than one year from the date of the Transactions.

The following is a description of the methods used to determine the fair values of significant assets and liabilities.

In-process research and development ("IPR&D") and other intangible asset

The IPR&D intangible asset represents the recording of the acquired IPR&D indefinite-lived intangible asset related to Recorlev. The other intangible asset
represents the commercial product in the form of Keveyis. The fair value for the IPR&D and other intangible assets were based on assumptions developed
by management and other information compiled by management including, but not limited to, discounted future expected cash flows. The fair value of
intangibles  relies  heavily  on  projected  future  net  cash  flows  including,  but  not  limited  to,  key  assumptions  for  revenue  and  operating  expenses.  The
discount rates used for intangible assets are

103

XERIS BIOPHARMA HOLDINGS, INC.

Notes to Consolidated Financial Statements

based on current market rates and reflect the risk inherent in each cash flow stream. The estimated useful life of the intangible asset of Keveyis is five years
which reflects the time period in which the Company expects to receive the benefits of the related cash flows.

Goodwill

The  excess  of  the  consideration  transferred  over  the  fair  value  of  assets  acquired  and  liabilities  assumed  was  recognized  as  goodwill.  The  goodwill  is
generated from operational synergies and cost savings the Company expects to achieve from the combined operations and Strongbridge’s knowledgeable
and experienced workforce. The majority of the goodwill is not expected to be deductible for tax purposes.

Transaction costs

In connection with the Transactions, the Company incurred significant expenses in the second through fourth quarter of 2021 such as transaction costs (e.g.,
bankers' fees, legal fees, consultant fees, etc.). Total transaction costs recorded in the selling, general and administrative expenses totaled $8.4 million for
the year ended December 31, 2021.

Supplemental pro forma information

The  following  unaudited  supplemental  pro  forma  financial  information  assumes  the  companies  were  combined  as  of  January  1,  2020.  The  pro  forma
financial  information  as  presented  below  is  for  informational  purposes  only  and  is  based  on  estimates  and  assumptions  that  have  been  made  solely  for
purposes  of  developing  such  pro  forma  information.  This  is  not  necessarily  indicative  of  the  results  of  operations  that  would  have  been  achieved  if  the
Acquisition had taken place on January 1, 2020, nor is it necessarily indicative of future results. Consequently, actual results could differ materially from
the unaudited pro forma financial information presented below. The following table presents the pro forma operating results as if Strongbridge had been
included in the Company's Condensed Consolidated Statements of Operations as of January 1, 2020 (unaudited, in thousands):

These  amounts  have  been  calculated  after  applying  the  Company’s  accounting  policies  and  adjusting  the  results  of  Xeris  to  reflect  the  additional
depreciation and amortization that would have been charged assuming the fair value adjustments to intangible assets had been applied on January 1, 2020.

The unaudited supplemental pro forma information above does not include any cost saving synergies from operating efficiencies. There is a tax impact on
the pro forma adjustments due to deferred tax liabilities being greater than the deferred tax assets in Ireland. For the other non-Irish entities, there is no tax
impact of the pro forma adjustments reflected as both companies are, and have been for some time, in net operating loss positions and have full valuation
allowances against their net deferred tax assets on both a historical and pro forma basis.

Note 4. Short-term investments

The Company classifies 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, 2021, 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, 2021 had an average remaining
maturity of 0.5 years. The debt securities are reported at fair value with unrealized gains or losses recorded in accumulated other comprehensive income
(loss)  in  the  consolidated  balance  sheet.  Refer  to  "Note  12  -  Fair  Value  Measurements",  for  information  related  to  the  fair  value  measurements  and

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, the Company 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, 2021 and 2020, 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.

In the third quarter of 2020, the Company commenced a plan to relocate the 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 incurred total restructuring costs of
approximately  $2.0  million  related  to  this  plan.  Costs  of  $0.3  million  were  incurred  in  the  year  ended  December  31,  2021,  all  of  which  is  included  in
research and development expenses in the consolidated statements of operations and comprehensive loss. The restructuring was materially completed in the
fourth quarter of 2021.

After the completion of the Acquisition on October 5, 2021, the Company undertook a strategic restructuring to streamline the organization and utilize the
operating expense synergy. The costs associated with the restructuring include employee termination. The Company expects to incur total restructuring cost
of approximately $11.1 million related to this plan. Costs of $9.7 million were incurred in the year ended December 31, 2021, of which $0.1 million is
included in research and development expenses, $9.4 million is included in selling, general and administrative expenses, and $0.2 million is included in
costs  of  goods  sold  in  the  consolidated  statements  of  operations  and  comprehensive  loss.  The  Company  anticipates  the  restructuring  related  to  the

In June 2020, Xeris Pharma completed a public offering of $86.3 million aggregate principal amount of Xeris Pharma'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.  Xeris  Pharma  incurred  debt  issuance  costs  of  $5.1  million  in  connection  with  the  issuance  of  the  Convertible  Notes.  Xeris  Pharma  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 dated June 30, 2020 (the “Base Indenture”), between Xeris
Pharma and U.S. Bank National Association, as trustee, as supplemented by the first supplemental indenture thereto dated June 30, 2020, between U.S.
Bank National Association, as trustee, and the second supplemental indenture

108

XERIS BIOPHARMA HOLDINGS, INC.

Notes to Consolidated Financial Statements

thereto dated October 5, 2021 ("the Supplemental Indentures" and together with the Base Indenture, the "Indenture"), among the Company, Xeris Pharma
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 Xeris Pharma’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, Xeris Pharma 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  Xeris  Pharma’s  common  stock.  Xeris  Pharma  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  Xeris  Pharma'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  Xeris  Pharma  is  not  a
holder thereof) preferred equity, if any, of the Company’s other direct and indirect subsidiaries.

As a result of the Transactions, and pursuant to the Second Supplemental Indenture, the Convertible Notes are no longer convertible into shares of common
stock of Xeris Pharma common stock. Instead, subject to the terms and conditions of the Indenture, the Convertible Notes will be exchangeable into cash
and  shares  of  common  stock  of  the  Company  in  proportion  to  the  transaction  consideration  payable  pursuant  to  the  Transaction  Agreement,  and  the
“Reference Property” provisions in the Indenture.

Pursuant to the Second Supplemental Indenture, the Company agreed to guarantee (a) the full and punctual payment when due of all monetary obligations
of Xeris Pharma under the Indenture and (b) the full and punctual performance within applicable grace periods of all other obligations of Xeris Pharma
under the Indenture.

Senior Secured Loan Facility

In  February  2018,  Xeris  Pharma  entered  into  the  Loan  and  Security  Agreement,  dated  as  of  February  28,  2018  (as  amended,  the  “Original  Loan
Agreement”), with Oxford Finance LLC (“Oxford”), as the collateral agent (in such capacity, the “Collateral Agent”) and a lender, 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"). Xeris Pharma also issued warrants to the Lenders to purchase common stock, which is further
discussed in "Note 11 - Warrants".

In September 2019, Xeris Pharma 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 Xeris Pharma 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”) were contingent on achievement of certain revenue targets which were not
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,  Xeris  Pharma  entered  into  that  certain  First  Amendment  to  Amended  and  Restated  Loan  and  Security  Agreement  with  the
Lenders  (the  “First  Amendment”)  to  amend  the  Loan  Agreement  to  allow  Xeris  Pharma  to  incur  indebtedness  under  the  U.S.  Small  Business
Administration (the “SBA”) the Paycheck Protection Program 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, Xeris Pharma entered into that certain Second Amendment to 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 Xeris Pharma's underwritten public offering
of  Xeris  Pharma's  5.00%  Convertible  Senior  Notes  due  2025  and  permit  the  Company  to  prepay  the  PPP  Loan  in  full.  The  Second  Amendment  also
provided for the extension of the interest-only payment period through December

109

XERIS BIOPHARMA HOLDINGS, INC.

Notes to Consolidated Financial Statements

31, 2021, after which the term loans would be payable in 30 equal monthly installments. However, if Xeris Pharma achieved a certain revenue milestone
prior to January 1, 2022, then the period for interest-only payments would be extended through September 30, 2022, after which the term loans would 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, Xeris Pharma 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, Xeris Pharma 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, Xeris Pharma entered into that certain Third Amendment to 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 Xeris Pharma’s new leased laboratory space and (ii) permit the sale of certain equipment
related to the relocation of Xeris Pharma’s research and development laboratory from San Diego to Chicago.

On October 23, 2020, Xeris Pharma entered into that certain Fourth Amendment to Amended and Restated Loan and Security Agreement with the Lenders
(the "Fourth Amendment") to amend the 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.

On May 3, 2021, Xeris Pharma entered into that certain Fifth Amendment to Amended and Restated Loan and Security Agreement with the Lenders (the
“Fifth Amendment”) to amend the Loan Agreement. The Fifth Amendment provides that if Xeris Pharma achieves a certain revenue milestone prior to
November 30, 2021, then the period for interest-only payments is extended six months to July 2022 and the Term Loan will be payable in 24 equal monthly
installments. If Xeris Pharma achieves another revenue milestone prior to May 31, 2022, the period for interest-only payments is further extended three
months,  to  October  2022  and  the  Term  Loan  will  be  payable  in  21  equal  monthly  installments.  If  Xeris  Pharma  achieves  a  third  revenue  milestone  by
August 31, 2022, the period for interest-only payments is further extended three months, to January 2023 and the Term Loan will be payable in 18 equal
monthly installments. The Company achieved all revenue milestones and therefore classified the amounts due under the Amended Loan Agreement as non-
current on the balance sheet as of December 31, 2021.

On May 24, 2021, Xeris Pharma entered into that certain Consent Under Amended and Restated Loan and Security Agreement (the “Consent”) with the
Lenders  to  permit  the  Company  to  execute,  deliver  and  perform  (a)  the  Transaction  Agreement  with  Strongbridge  and  (b)  that  certain  Expenses
Reimbursement Agreement dated as of May 24, 2021 by and between Xeris Pharma and Strongbridge pursuant to which Xeris Pharma and Strongbridge
agreed to certain reimbursement obligations related to the transactions contemplated by the Transaction Agreement.

In  connection  with  the  completion  of  the  Transactions,  on  October  5,  2021,  the  Company  entered  into  that  certain  Joinder  and  Sixth  Amendment  to
Amended and Restated Loan and Security Agreement (the “Sixth Amendment”) with Xeris Pharma, the Lenders and Strongbridge US, Inc. (“Strongbridge
US”) (each of Strongbridge US and the Company, a “New Borrower”) to amend the Loan Agreement. The Sixth Amendment adds the New Borrowers as
borrowers under the Loan Agreement and provides for the grant by the New Borrowers to the Collateral Agent, for the ratable benefits of the Lenders, a
first priority security interest on substantially all of their assets, including intellectual property, subject to certain exceptions. The Sixth Amendment also
updates certain negative covenants and definitions to among, other things, permit certain intercompany arrangements and restructuring activities, as well as
modifies  the  revenue  milestones  to  address  both  Gvoke  and  non-Gvoke  revenues.  The  Company  achieved  each  revenue  milestone  and  has  therefore
classified  the  amounts  due  under  the  Loan  Agreement  (as  amended  by  that  certain  First  Amendment,  Second  Amendment,  Third  Amendment,  Fourth
Amendment, Fifth Amendment, Consent and Sixth Amendment, the “Amended Loan Agreement") as non-current on the balance sheet as of December 31,
2021.

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  (or,  the  LIBOR  replacement  rate  as  applicable).  For  the  period  from  the  funding  date  of  the  Term  A  Loan  through  and  including
December  31,  2021,  the  interest  rate  was  8.68%.  The  Company  has  incurred  total  debt  issuance  costs  of  $2.0  million  related  to  the  Original  Loan
Agreement and the Amended Loan Agreement, which are being amortized to interest expense over the life of the loan using the effective interest method.
The remaining balance of unamortized debt issuance costs have been reflected as a direct reduction to the loan balance.

Notes to Consolidated Financial Statements

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.

Note 12. Fair value measurements

Fair  value  is  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between  market  participants  at  the
measurement date. Fair value measurements are classified and disclosed in one of the following categories:

Level 1: Measured using unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or
liabilities;

Level 2: Measured using quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in
markets that are not active, or inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

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 the 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  uncertainty  of  the  fair  value  measurement  due  to  the  use  of
unobservable inputs and interrelationships between these unobservable inputs could have resulted in higher or lower fair value measurement.

Notes to Consolidated Financial Statements

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):

Balance at December 31, 2020

Contingent Value Rights

$

$

159 
908 
702 
1,769 

The fair value of the CVRs is calculated by using a discounted cash flow method for the Keveyis patent milestone and an option pricing method for the
Recorlev and Keveyis sales milestones. In the case of Keveyis milestones, the Company applies a scenario-based method and weighted them based on the
possible achievement of the milestone. This fair value measurement is based on significant inputs not observable in the market and thus represents a Level
3 measurement as defined in ASC 820, Fair Value Measurement. The key assumptions used include the discount rate and sales growth. The estimated value
of the CVR consideration is preliminary only and is based upon available information and certain assumptions which the Company's management believes
are reasonable under the circumstances. The ultimate payout under the CVRs may differ materially from the assumptions used in determining the fair value
of the CVR consideration.

Contingent consideration obligations are recorded at their estimated fair values and these obligations are revalued each reporting period until the related
contingencies are resolved. The contingent value rights are adjusted to fair value using the methods described above at the end of each reporting period.
Significant changes which increase or decrease the probabilities of achieving the related milestones or shorten or lengthen the time required to achieve such
events would result in corresponding increases or decreases in the fair values of these obligations.

As of December 31, 2021, the CVRs were revalued at $22.5 million using the same methods described above. During the period from October 5, 2021 to
December  31,  2021,  no  gains  or  losses  were  recognized  in  the  consolidated  statements  of  operations  from  changes  in  the  fair  values  of  the  CVRs.  See
"Note 16 – Commitments and contingencies" for a discussion of the CVRs.

There were no transfers between any of the levels of the fair value hierarchy during the years ended December 31, 2021 and 2020.

Note 13. Stockholders' equity

The  Company’s  375.0  million  authorized  shares  of  stock  are  divided  into  350.0  million  shares  of  common  stock,  par  value  $0.0001  per  share,  and
25.0 million shares of undesignated preferred stock, par value $0.0001 per share. At December 31, 2021 none of the 25.0 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 the common stock during the periods presented.

In February 2020, the Company completed an equity offering of the 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 the 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.

In March 2021, the Company completed a registered direct offering of 6,553,398 shares of the common stock at a price of $4.12 per share. Net proceeds
from the equity offering were approximately $26.9 million after deducting offering expenses.

Notes to Consolidated Financial Statements

On October 5, 2021, the Company completed the acquisition of Strongbridge. Upon completion of the Merger, (a) each share of Xeris Pharma common
stock was assumed by the Company and converted into the right to receive one Company Share and any cash in lieu of fractional entitlements due to a
Xeris Pharma shareholder and (b) each Xeris Pharma option, stock appreciation right, restricted share award and other Xeris Pharma share based award that
was  outstanding  was  assumed  by  the  Company  and  converted  into  an  equivalent  equity  award  of  the  Company,  which  award  was  subject  to  the  same
number of shares and the same terms and conditions as were applicable to the Xeris Pharma award in respect of which it was issued.

Upon completion of the Merger, the Company acquired all of the outstanding Strongbridge Shares in exchange for (i) 0.7840 of a share of the Company
Shares and cash in lieu of fractions of Company Shares in exchange for each Strongbridge Share held by such Strongbridge Shareholders and (ii) one CVR.
Strongbridge’s outstanding equity awards were treated as set forth in the Transaction Agreement, such that (i) each Strongbridge Share Award was vested
and  settled  for  Strongbridge  Shares  immediately  prior  to  the  effective  time  of  the  Scheme,  (ii)  each  Strongbridge  Option  became  fully  vested  and
exercisable immediately prior to the effective time of the Scheme, (iii) each unexercised Strongbridge Option was assumed by the Company and converted
into an option to purchase Company Shares.

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, 2021, 458,416 RSUs vested for which
141,644 shares were withheld to cover the minimum statutory withholding taxes of $0.5 million. 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 14. 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,  2021  and  2020,  the  number  of  shares  of  common  stock
available for issuance under the 2018 Plan was automatically increased by 2,384,448 shares and 1,088,580 shares, respectively. As of December 31, 2021,
there were 1,569,336 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. 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, 2021 and 2020, the number
of  shares  of  common  stock  available  for  issuance  under  the  ESPP  increased  by  386,000  shares  and  272,145  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 215,939 shares at a weighted average price of $2.98 per share during the year ended December 31, 2021. As of December 31, 2021, there
were 477,727 shares available for issuance under the ESPP.

Notes to Consolidated Financial Statements

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 uses 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, 2021, there were 197,621 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.

Assumed Plans

At the effective time of the Scheme, Strongbridge’s outstanding equity awards were treated as set forth in the Transaction Agreement, such that (i) each
Strongbridge Share Award was vested and settled for Strongbridge Shares immediately prior to the effective time of the Scheme, (ii) each Strongbridge
Option became fully vested and exercisable immediately prior to the effective time of the Scheme, (iii) each unexercised Strongbridge Option was assumed
by the Company and converted into an option to purchase Company Shares (each, a “Strongbridge Rollover Option”), with the exercise price per Company
Share and the number of Company Shares underlying the Strongbridge Rollover Option adjusted to reflect the conversion from Strongbridge Shares into
Company Shares, provided that each Strongbridge Rollover Option will continue to have, and be subject to, the same terms and conditions that applied to
the corresponding Strongbridge Rollover Option (except for terms rendered inoperative by reason of the Acquisition or for immaterial administrative or
ministerial changes that are not adverse to any holder other than in any de minimis respect), provided that the terms of each Strongbridge Rollover Option
with an exercise price of $4.50 or less (prior to the adjustment described above) were amended to provide that it shall remain exercisable for a period of
time following the effective time of the Scheme equal to the lesser of (A) the maximum remaining term of such corresponding Strongbridge Option and (B)
the fourth anniversary of the effective date of the Merger, in each case regardless of whether the holder of such Strongbridge Rollover Option experiences a
termination of employment or service on or following the effective time of the Scheme.

On the acquisition closing date, the Company assumed all then-outstanding stock options and shares available and reserved for issuance under some legacy
equity incentive plans of Strongbridge, including the Strongbridge 2015 equity compensation plan and Strongbridge 2017 inducement plan (collectively,
the “Assumed Plans”). Shares reserved under the Assumed Plans will be available for future grants. The Company also assumed all then-outstanding stock
options  from  the  rest  of  the  legacy  equity  incentive  plans  of  Strongbridge  without  assuming  the  shares  available  and  reserved  for  issuance  under  these
plans. The number of shares subject to stock options outstanding under all Strongbridge legacy equity incentive plans are included in the tables below. As
of December 31, 2021, there were 2.9 million shares reserved for future grants under the Assumed Plans.

CVRs were also issued to the holders of Strongbridge vested and unexercised options that were outstanding and assumed by the Company at the acquisition
date.

Stock options

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.

116

XERIS BIOPHARMA HOLDINGS, INC.

Notes to Consolidated Financial Statements

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 the 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.

The fair value of stock options granted was estimated with the following weighted average assumptions:

Restricted Share Units

The Company grants RSUs to employees. RSUs that are granted vest over either three or four years in equal annual installments beginning on the one-year
anniversary of the date of grant, provided that the employee is employed by the Company on such vesting date. If and when the RSUs vest, the Company
will issue one share of common stock for each whole RSU that has vested, subject to satisfaction of the employee’s tax withholding obligations. Stock-
based compensation expense related to RSUs is recognized on a straight-line basis over the employee’s requisite service period.

Note 15. Other employee benefit plans

Defined Contribution Plan

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, 2021 and 2020, the Company made
$0.7 million and $0.6 million of matching contributions to the plan, respectively.

Deferred 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, 2021, the total deferred compensation liability under the Deferred Compensation Plan
was approximately $1.6 million and was recorded in other current liabilities in the consolidated balance sheets.

Note 16. Commitments and contingencies

Commitments

Commitments to Taro Pharmaceuticals U.S.A., Inc. ("Taro")

Upon  the  completion  of  Strongbridge  acquisition,  the  Company  also  acquired  the  supply  agreement  Strongbridge  had  with  Taro  to  produce  Keveyis.
Strongbridge was obligated to purchase annual minimum amounts of product totaling approximately $29.1 million over a six-year period from Taro. As of
December 31, 2021, the remaining obligation under the Supply Agreement was $14.1 million. The agreement with Taro may extend beyond the orphan
exclusivity  period  unless  terminated  by  either  party  pursuant  to  the  terms  of  the  agreement.  If  terminated  by  Taro  at  the  conclusion  of  the  orphan
exclusivity period, the Company has the right to manufacture the product on its own or has the product manufactured by a third party on its behalf. The
Company is also required to reimburse Taro for royalty obligation resulting from its sale of Keveyis to the Company.

Indemnifications

In the ordinary course of business and in connection with the sale of assets and businesses and other transactions, the Company often agrees to indemnify
our counterparties against certain liabilities that may arise in connection with a transaction or that are related to events and activities prior to or following a
transaction,  such  as  breaches  of  contracts,  unfavorable  tax  consequences  and  employee  liabilities.  If  a  counterparty  were  to  make  a  successful
indemnification  claim  against  us,  the  Company  may  be  required  to  reimburse  the  loss  and  such  amount  could  be  material  to  our  consolidated  financial
statements. Where appropriate, the obligation for such indemnifications is recorded as a liability. Because these agreements generally do not specify the
maximum amount of indemnification a counterparty may be entitled to, the overall maximum amount of our potential indemnification liability under these
agreements  cannot  be  reasonably  estimated.  However,  the  Company  believes  that  the  likelihood  of  a  material  liability  being  triggered  under  these
indemnification obligations is not probable at this time.

Leases

The Company has non-cancellable operating leases for office and laboratory space, which expire at various times in 2031 and 2033. The non-cancellable
lease agreements provide for monthly lease payments which increase during the term of each lease agreement.

As of December 31, 2021, the Company had unused letters of credit of $1.4 million which were issued primarily to secure leases.

Contingencies

CVR liability

Upon  closing  the  Transactions,  the  Company  entered  into  a  CVR  Agreement.  Each  CVR  entitles  its  holder  to  receive  additional  consideration  of  up  to
$1.00,  to  satisfy  future  performance  milestones,  settleable  in  cash,  common  stock,  or  a  combination  of  cash  and  common  stock,  at  the  Company's  sole
election. As of the acquisition closing date, there were approximately 74.1 million CVRs. There will be additional issuance of up to 10.5 million CVRs to
holders of Strongbridge rollover options and assumed warrants upon exercise.

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,  2021,
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 17. 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 following potentially dilutive securities were excluded from the computation of diluted weighted average common shares outstanding due to their anti-
dilutive effect:

Shares to be issued upon conversion of Convertible Notes
Vested and unvested stock options
Restricted stock units
Warrants

The benefit for income taxes for 2020 is attributable to an Australian research and development tax incentive that was refunded to the Company based on
the 2020 income tax filing.

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  years  ended
December  31,  2021  and  2020,  the  Company  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
       Total assets
Deferred tax liabilities:

As of December 31, 2021, the Company had federal net operating loss carryforwards of $475.7 million and various state net operating loss carryforwards
of $309.7 million. 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. 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,  2021,  the  Company  had  $5.4  million  and  $2.5  million  of  federal  and  state  income  tax  credits,  respectively,  to  reduce  future  tax
liabilities. 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. 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.

A  reconciliation  of  the  beginning  and  ending  amounts  of  valuation  allowances  for  the  years  ended  December  31,  2021  and  2020  is  as  follows  (in

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, 2021 and 2020, excluding

For the year ended December 31, 2021, 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  $0.6  million  were  offset  against  deferred  tax  assets.  Tax  years  prior  to  2018  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, 2021 and 2020, the Company incurred no interest and penalties related to income taxes.

19. Subsequent events

Private placement

On  January  3,  2022,  the  Company  entered  into  a  securities  purchase  agreement  in  connection  with  a  private  placement  with  an  affiliate  of  Armistice
Capital, LLC (“Armistice”) for aggregate gross proceeds of approximately $30.0 million. In accordance with the purchase agreement, the Company issued
to Armistice an aggregate of (i) 10,238,908 shares of the Company’s common stock, par value $0.0001 per share at a purchase price of $2.93 per share, and
(ii) warrants to purchase an aggregate of 5,119,454 shares of the Company's common stock at an exercise price of $3.223 per share. The warrants became
exercisable immediately upon the closing of

the transaction and have a term of five years from the earliest of the date (a) of effectiveness of the resale registration statement, which was February 7,
2022, (b) all of the shares and the Company's common stock issuable upon exercise of the warrants (the “Warrant Shares”) have been sold pursuant to Rule
144 or may be sold pursuant to Rule 144 without the requirement for the Company to be in compliance with the current public information required under
Rule 144 and without volume or manner-of-sale restrictions, (c) following the one-year anniversary of the date of closing provided that the holder of Shares
or Warrant Shares is not an affiliate of the Company, or (d) all of the shares and Warrant Shares may be sold pursuant to an exemption from registration
under Section 4(a)(1) of the Securities Act without volume or manner-of-sale restrictions.

Loan facility

In March 2022, the Company, Xeris Pharma and certain subsidiary guarantors of the Company entered into a Credit Agreement and Guaranty (the "Hayfin
Loan Agreement") with the lenders from time to time parties thereto (the “New Lenders”) and Hayfin Services LLP, as administrative agent for the New
Lenders,  pursuant  to  which  the  Company  and  its  subsidiaries  party  thereto  granted  a  first  priority  security  interest  on  substantially  all  of  their  assets,
including intellectual property, subject to certain exceptions. The Hayfin Loan Agreement provided for the New Lenders to extend $100.0 million in term
loans (the “Initial Loan”) to the Company on the closing date and up to an additional $50.0 million in delayed draw term loans during the one year period
immediately following the closing date (the “Delayed Draw Term Loans” and, together with the Initial Loan, the “Loans”) in no more than three drawings
of no less than $10.0 million per drawing, subject to the Company being in pro forma compliance with the financial covenants and other conditions set
forth therein. In conjunction with the execution of the Hayfin Loan Agreement, the Amended Loan Agreement balance of $43.5 million was repaid in full
and fees of $2.1 million in connection with the loan repayment were paid. In addition to utilizing the proceeds to repay the obligations under the Amended
Loan Agreement in full, the proceeds will otherwise be used for general corporate purposes. After repayment, the Loans may not be re-borrowed.

The New Lenders also received warrants to purchase 1,315,789 shares of the common stock of the Company at a price of $2.28 per share (the “Warrants").
The  Warrants  are  (i)  exercisable  until  the  seventh  (7th)  anniversary  of  the  closing  date;  (ii)  freely  transferable  and  detachable  from  the  Loans;  and  (iii)
subject to customary warrant holder rights and protections, including structural-based anti-dilution protection and adjustments for stock dividends, splits,
combinations, reclassifications and the like.

All of the Loans incur interest at a floating per annum rate in an amount equal to the sum of (i) 9.0% (or 8.0% per annum if the replacement rate in effect is
the Wall Street Journal Prime Rate) plus (ii) the greater of (x) (1) CME Group Benchmark Administration Limited (CBA) Term SOFR (or the replacement
rate, if applicable) if CBA Term SOFR is greater than 1.00% plus 0.26161% or (2) 1.00% if CME Term SOFR is less than 1.00% and (y) one percent
(1.00%)  per  annum  (or  2.0%  per  annum  if  the  replacement  rate  in  effect  is  the  Wall  Street  Journal  Prime  Rate).  The  Company  has  incurred  total  debt
issuance costs of approximately $6.1 million related to the Hayfin Loan Agreement, which are being amortized to interest expense over the life of the loan
using the effective interest method. The remaining balance of unamortized debt issuance costs have been reflected as a direct reduction to the loan balance.

The  Hayfin  Loan  Agreement  allows  the  Company  to  voluntarily  prepay  the  outstanding  amounts  thereunder.  The  Company  is  subject  to  an  early
prepayment fee equal to (i) for any prepayment that occurs prior to the second anniversary of the closing date, the applicable make-whole amount, (ii) for
any prepayment that occurs after the second anniversary of the closing date but on or prior to the fourth anniversary of the closing date: (x) the amount of
any principal so prepaid, multiplied by (y) for any prepayment that occurs (A) after the second anniversary of the closing date and on or prior to the third
anniversary  of  the  closing  date,  five  percent  (5.0%),  (B)  after  the  third  anniversary  of  the  closing  date  and  on  or  prior  to  the  fourth  anniversary  of  the
closing date, three percent (3.0%), and (C) after the fourth anniversary of the closing date, zero percent (0.0%).

The  Hayfin  Loan  Agreement  contains  customary  representations  and  warranties,  events  of  default  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.

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 on such evaluation, our principal executive officer and principal financial officer have concluded that the disclosure controls and procedures
were effective as of December 31, 2021 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, 2021 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, 2021.

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 were 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,  2021  that  have  materially  affected,  or  are  reasonably  likely  to
materially affect, our internal control over financial reporting.

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES AND EXCHANGE ACT OF 1934, AS AMENDED

The common stock, par value $0.0001 per share (“Common Stock”) of Xeris Biopharma Holdings, Inc. (the “Company,” “we,” “us,” and “our”)

is registered under Section 12 of the Securities Exchange Act of 1934, as amended. The following description sets forth certain general terms and
provisions of our Common Stock. These descriptions are in all respects subject to and qualified in their entirety by, and should be read in conjunction with
the applicable provisions of, our Amended and Restated Certificate of Incorporation (“Certificate of Incorporation”) and our Amended and Restated
Bylaws (“Bylaws”), each of which are incorporated by reference as an exhibit to the Annual Report on Form 10-K of which this Exhibit 4.3 is a part, and
by applicable law. We encourage you to read our Certificate of Incorporation, our Bylaws and the applicable provisions of the Delaware General
Corporation Law for additional information.

Authorized Capital Stock

Our authorized capital stock consists of 350,000,000 shares of Common Stock and 25,000,000 shares of preferred stock, par value $0.0001 per share

(“Preferred Stock”), all of which shares of Preferred Stock are undesignated.

Common Stock    

Only our Common Stock is registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Holders of our Common Stock are entitled to one vote for each share of Common Stock held of record for the election of directors and on all matters

submitted to a vote of the stockholders. Holders of our Common Stock are entitled to receive dividends as may be declared from time to time by our board
of directors out of funds legally available therefor. The holders of our Common Stock do not have any cumulative voting rights. Holders of our Common
Stock have no preemptive, subscription, redemption or conversion rights, and no sinking fund provisions are applicable to our Common Stock.

In the event of our dissolution, liquidation or winding up, holders of our Common Stock are entitled to share pro rata in our net assets legally

available after the payment of all our debts and other liabilities, subject to the preferential rights of any Preferred Stock then outstanding. The rights,
preferences and privileges of holders of Common Stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of
Preferred Stock that we may designate and issue in the future.

Preferred Stock

Our board of directors is authorized, without further action by the stockholders, to designate and issue up to an aggregate of 25,000,000 shares of
Preferred Stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and privileges could
include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares
constituting, or the designation of, such series, any or all of which may be greater than the rights of Common Stock. Our board of directors may authorize
the issuance of Preferred Stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of Common
Stock and the likelihood that such holders will receive dividend payments and payments upon our liquidation.

The purpose of authorizing our board of directors to issue Preferred Stock in one or more series and determine the number of shares in the series and
its rights, preferences, privileges and restrictions is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of Preferred
Stock, while providing flexibility in connection with possible future financings and acquisitions and other corporate purposes, could, under certain
circumstances, have the effect of delaying, deferring or preventing a change in control of our company, as further discussed below under “—Anti-Takeover
Effects of Delaware Law and Provisions of our Charter and our Bylaws—Provisions of our Charter and our Bylaws—Undesignated Preferred Stock.”

No shares of Preferred Stock are outstanding as of the date of our Annual Report on Form 10-K with which this Exhibit 4.3 is filed as an exhibit.

Registration Rights

Pursuant to the terms of Xeris Pharma’s investors’ rights agreement, dated as of December 31, 2015, certain of our stockholders are entitled to rights

with respect to the registration of their shares under the Securities Act until the earliest of the fifth (5th) anniversary of our initial public offering, or such
holder’s registrable securities could be sold without any restriction on volume or manner of sale on any 90-day period under Rule 144 or any successor
rule, as described below. We refer to these shares collectively as registrable securities.

Demand Registration Rights

The holders of 1,387,985 shares of our Common Stock are entitled to demand registration rights. Under the terms of the investors’ rights agreement,
we will be required, upon the written request of holders of at least 20% of the securities eligible for registration then outstanding or such lesser percentage
that would result in an aggregate offering price of at least $10.0 million, to file a registration statement and use commercially reasonable efforts to effect the
registration of all or a portion of these shares for public resale. We are required to effect only two registrations pursuant to this provision of the investors’
rights agreement.

Short-Form Registration Rights

Pursuant to Xeris Pharma’s investors’ rights agreement, if we are eligible to file a registration statement on Form S-3, upon the written request of

majority in interest of these holders to sell registrable securities at an aggregate price of at least $1.0 million, we will be required to use commercially
reasonable efforts to effect a registration of such shares. We are not required to effect more than two registrations that have been declared or ordered
effective by the SEC pursuant to this provision of the investors’ rights agreement. The right to have such shares registered on Form S-3 is further subject to
other specified conditions and limitations.

Piggyback Registration Rights

Pursuant to Xeris Pharma’s investors’ rights agreement, if we register any of our securities either for our own account or for the account of other

security holders, the holders of 1,387,985 shares of our Common Stock are entitled to include their shares in the registration. Subject to certain exceptions
contained in the investors’ rights agreement, we and the underwriters may limit the number of shares included in the underwritten offering to the number of
shares which we and the underwriters determine in our sole discretion will not jeopardize the success of the offering.

Indemnification

Xeris Pharma’s investors’ rights agreement contains customary cross-indemnification provisions, under which we are obligated to indemnify holders

of registrable securities in the event of material misstatements or omissions in the registration statement attributable to us, and they are obligated to
indemnify us for material misstatements or omissions attributable to them.

Expiration of Registration Rights

The demand registration rights and short form registration rights granted under Xeris Pharma’s investors’ rights agreement will terminate on the fifth

anniversary of the completion of Xeris Pharma’s initial public offering or at such time after such offering when the holders’ shares may be sold without
restriction pursuant to Rule 144 within a 90-day period.

Anti-Takeover Effects of Delaware Law and Provisions of our Certificate of Incorporation and our Bylaws

Our Certificate of Incorporation and Bylaws include a number of provisions that may have the effect of delaying, deferring or preventing another
party from acquiring control of us and encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our
board of directors rather than pursue non-negotiated takeover attempts. These provisions include the items described below.

Delaware Anti-Takeover Statute

We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly held Delaware

corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder
becomes an interested stockholder, unless the business combination is approved in a prescribed manner. Under Section 203, a business combination
between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

 
 
•

•

•

  before the stockholder became interested, our board of directors approved either the business combination or the transaction which resulted

in the stockholder becoming an interested stockholder;

  upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder
owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of
determining the voting stock outstanding, shares owned by persons who are directors and also officers, and employee stock plans, in some
instances, but not the outstanding voting stock owned by the interested stockholder; or

  at or after the time the stockholder became interested, the business combination was approved by our board of directors and authorized at an

annual or special meeting of the stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock which is not
owned by the interested stockholder.

Section 203 defines a business combination to include:

•

•

•

•

•

  any merger or consolidation involving the corporation and the interested stockholder;

  any sale, transfer, lease, pledge or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;

  subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the

interested stockholder;

  subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any

class or series of the corporation beneficially owned by the interested stockholder; and

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or
through the corporation.

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of

the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

Choice of Forum

Our bylaws provide that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be
the sole and exclusive forum for any state law claims for (i) any derivative action or proceeding brought on behalf of the company, (ii) any action asserting
a claim of, or a claim based on, a breach of a fiduciary duty owed by any company director, officer or other employee to the company or our stockholders,
(iii) any action asserting a claim arising pursuant to any provision of the DGCL, or (iv) any action asserting a claim 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 under the Securities Act or the Securities
Exchange Act of 1934. In addition, our bylaws further provide that the federal district courts of the United States will be the exclusive forum for resolving
any complaint asserting a cause of action arising under the Securities Act (the “Federal Forum Provision”).

Our 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.

We 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. 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 Court of Chancery of the State

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
of Delaware or the federal district courts of the United States, as applicable, 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.

Provisions of our Charter and our Bylaws

Our Certificate of Incorporation and Bylaws include a number of provisions that may have the effect of delaying, deferring or preventing another
party from acquiring control of us and encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our
board of directors rather than pursue non-negotiated takeover attempts. These provisions include the items described below.

Board Composition and Filling Vacancies 

Our Certificate of Incorporation provides for the division of our board of directors into three classes serving staggered three-year terms, with one

class being elected each year. Our Certificate of Incorporation also provides that directors may be removed only for cause and then only by the affirmative
vote of the holders of two-thirds or more of the shares then entitled to vote at an election of directors. Furthermore, any vacancy on our board of directors,
however occurring, including a vacancy resulting from an increase in the size of our board, may only be filled by the affirmative vote of a majority of our
directors then in office even if less than a quorum. The classification of directors, together with the limitations on removal of directors and treatment of
vacancies, has the effect of making it more difficult for stockholders to change the composition of our board of directors.

Meetings of Stockholders

Our Certificate of Incorporation and Bylaws provide that special meetings of stockholders may be called at any time by the board of directors, or by a
majority of the members of the board of directors, or by a committee of the board of directors which has been duly designated by the board of directors and
whose powers and authority, as provided in a resolution of the board of directors or in these Bylaws, include the power to call such meetings, but such
special meetings may not be called by any other person or persons.

Advance Notice Requirements

Our Bylaws provide that stockholders must give timely written notice to bring business before an annual meeting of stockholders or to nominate

candidates for election as directors at an annual meeting of stockholders. Generally, to be timely, a stockholder’s notice will be required to be delivered to
our principal executive offices not later than the 90th day nor earlier than the 120th day prior to the one (1)-year anniversary of the preceding year’s annual
meeting; provided, however, that if the date of the annual meeting is more than thirty (30) days before or more than sixty (60) days after such anniversary
date, notice by the stockholder to be timely must be so delivered, or mailed and received, not later than the 90th day prior to such annual meeting or, if
later, the tenth day following the day on which public disclosure of the date of such annual meeting was first made. Our Bylaws also specify the form and
content of a stockholder’s notice.

Amendment to Bylaws

Our board of directors is authorized to amend, alter, change, adopt and repeal our Bylaws by a majority vote. Our stockholders also have the power to
amend, alter, change, adopt and repeal our Bylaws by the affirmative vote of the holders of two-thirds or more of the shares then entitled to vote on such an
amendment or repeal, voting as a single class; provided, however, that if our board of directors recommends that stockholders approve such amendment or
repeal at such meeting of stockholders, such amendment or repeal shall only require the affirmative vote of the majority of outstanding shares entitled to
vote on such amendment or repeal, voting together as a single class.

Undesignated Preferred Stock

Our Certificate of Incorporation provides for 25,000,000 authorized shares of Preferred Stock. The existence of authorized but unissued shares of
Preferred Stock may enable our board of directors to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or
otherwise. For example, if in the due exercise of its fiduciary obligations, our board of directors were to determine that a takeover proposal is not in the best
interests of our stockholders, our board of directors could cause shares of Preferred Stock to be issued without stockholder approval in one or more private
offerings or other transactions that might dilute the voting or other rights of the proposed acquirer or insurgent stockholder or stockholder group. In this
regard, our certificate of

incorporation grants our board of directors broad power to establish the rights and preferences of authorized and unissued shares of Preferred Stock. The
issuance of shares of Preferred Stock could decrease the amount of earnings and assets available for distribution to holders of shares of Common Stock.
The issuance may also adversely affect the rights and powers, including voting rights, of these holders and may have the effect of delaying, deterring or
preventing a change in control of us.

Nasdaq Global Select Market Listing

Our Common Stock is listed on The Nasdaq Global Select Market under the symbol “XERS.”

Transfer Agent and Registrar

The transfer agent and registrar for our Common Stock is Computershare Trust Company, N.A. The transfer agent and registrar’s address is 250

Royall Street, Canton, Massachusetts 02021, and its telephone number is (800) 962-4284.
