obtained this industry and business information, market data, prevalence information and other data from reports, research surveys, studies and
similar data prepared by market research firms and other third parties; industry, medical and general publications; government data; and similar
sources, in some cases applying our own assumptions and analysis that may, in the future, prove not to have been accurate.

Summary of Risks Related to our Business

Our business, prospects, financial condition, and operating results are subject to numerous risks and uncertainties that you should be aware

of before making an investment decision, as more fully described under Part I, Item 1A, Risk Factors and elsewhere in this Annual Report.
These risks may include, but are not limited to, the following:

•

•

•

•

•

•

Our commercialization efforts in the U.S. with respect to ZULRESSO® (brexanolone) CIV injection may never be successful and we
may never be able to generate meaningful revenues, or revenues at levels or on timing necessary to support our investment and goals.

Our future business depends heavily on our and our collaborators’ ability to successfully develop and gain regulatory approval of our
current product candidates, including zuranolone (SAGE-217), which is in Phase 3 clinical development for major depressive
disorder and postpartum depression.  We cannot be certain that we or our collaborators will be able to complete ongoing clinical
trials, initiate new clinical trials or announce results of clinical trials on the timelines we expect or at all. We cannot be certain that we
or our collaborators will be able to successfully develop, file for or obtain regulatory approval for, or successfully commercialize, any
of our current or future product candidates.

Obtaining regulatory approval to market any of our product candidates is a complex, lengthy, expensive and uncertain process, and
the U.S. Food and Drug Administration and regulatory authorities outside of the U.S. may delay, limit or deny approval of any of our
product candidates for many reasons.

If the affected populations for indications our products and product candidates are targeting or the addressable markets within such
populations are smaller than we anticipate, our ability to achieve profits from the commercialization of our products and product
candidates, if successfully developed and approved, at the levels or on the timing we expect could be materially adversely impacted.  

Positive results from non-clinical studies and clinical trials of our product candidates are not necessarily predictive of the results of
later non-clinical studies and clinical trials of our product candidates in the same indications or other indications. Interim results from
non-clinical studies and clinical trials may not be predictive of results of such non-clinical studies or clinical trials once completed.

If serious adverse events or other undesirable side effects are identified during the use of any of our marketed products or product
candidates, including during commercial use or in clinical trials, such events may adversely affect market acceptance or result in
other significant negative consequences for an approved product; delay or prevent further development or regulatory approval with
respect to product candidates; or cause regulatory

 
 
 
 
 
 
 
 
 
authorities to require labeling statements, such as boxed warnings, or a Risk Evaluation and Mitigation Strategy, on approved
products.

• We rely completely on third-party suppliers to manufacture commercial supplies of ZULRESSO and clinical drug supplies for our

product candidates.

•

•

•

Our current product candidates, if successfully developed and approved, and other future products, if any, may not achieve broad
market acceptance or reimbursement at sufficient levels, which may limit the revenue that we generate from sales of such products.

Competing therapies may exist or could emerge that adversely affect the amount of revenue we are able to generate from the sale of
ZULRESSO or any of our current or future product candidates, if successfully developed and approved.

Our existing and future collaborations, if any, may not lead to the successful development or regulatory approval of product
candidates or commercialization of products.  

• We may not be successful in our efforts to identify new targets, generate new compounds, and successfully bring such new

compounds through investigational new drug application-enabling non-clinical studies.

•

•

•

If we are unable to adequately protect our proprietary technology, or obtain and maintain issued patents that are sufficient to protect
our products or product candidates, others could compete against us more directly, which would have a material adverse impact on
our business, results of operations, financial condition and prospects.

For certain of our products and product candidates, we are dependent on licensed intellectual property.  If we were to lose our rights
to licensed intellectual property, we may not be able to continue developing or commercializing certain of our products or product
candidates, if approved.

Existing or future laws, regulations, executive orders or policies aimed at reducing healthcare costs may have a material adverse
effect on our business or results of operation.

• We are subject to healthcare laws and regulations, which could expose us to the risk of criminal sanctions, civil penalties, contractual
damages, reputational harm and diminished profits and future earnings if we or our employees are alleged or determined not to have
complied with such laws and regulations.

• We are a biopharmaceutical company with a limited operating history, and have not generated significant revenue to date. We have

incurred significant operating losses since our inception, and anticipate that we will incur continued losses for the foreseeable future.

• We may need to raise additional funding, which may not be available on acceptable terms, or at all. Raising additional capital, even

opportunistically, may cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights.

•

The COVID-19 pandemic may continue to adversely impact our business, including our sales of ZULRESSO and our initiation,
conduct and completion of clinical trials.

Item 1. Business

Overview

We are a biopharmaceutical company committed to developing and commercializing novel medicines with the potential to transform the

lives of people with debilitating disorders of the brain. Our first product, ZULRESSO® (brexanolone) CIV injection, is approved in the U.S.
for the treatment of postpartum depression, or PPD, in adults. We have a portfolio of other product candidates with a current focus on
modulating two critical central nervous system, or CNS, receptor systems, GABA and NMDA. The GABA receptor family, which is
recognized as the major inhibitory neurotransmitter in the CNS, mediates downstream neurologic and bodily function via activation of GABAA
receptors. The NMDA-type receptors of the glutamate receptor system are a major excitatory receptor system in the CNS. Dysfunction in these
systems is implicated in a broad range of CNS disorders. We are currently targeting diseases and disorders of the brain with three key focus
areas: depression, neurology and neuropsychiatry.

Our first product, ZULRESSO, is a proprietary intravenous, or IV, formulation of brexanolone, approved in the U.S. as a treatment for

PPD in adults. Brexanolone is chemically identical to allopregnanolone, a naturally occurring neuroactive steroid that acts as a positive
allosteric modulator of GABAA receptors. We launched ZULRESSO commercially in the U.S. in June 2019.

Our next most advanced product candidate is zuranolone (SAGE-217), a novel oral compound being developed for certain affective
disorders, including major depressive disorder, or MDD, and PPD.  Zuranolone is a neuroactive steroid that, like brexanolone, is a positive
allosteric modulator of GABAA receptors, targeting both synaptic and extrasynaptic GABAA receptors. We are currently conducting three
Phase 3 placebo-controlled clinical trials of zuranolone – the WATERFALL Study and the CORAL Study in MDD, and the SKYLARK Study
in PPD – as well as an open-label Phase 3 clinical trial in MDD known as the SHORELINE Study. We expect to report topline results from the
WATERFALL Study in the first half of 2021, and topline results from the other zuranolone Phase 3 clinical trials at various times throughout
the remainder of 2021.  

In addition to zuranolone, we have a portfolio of other novel compounds that target GABAA receptors, including SAGE-324.  SAGE-

324 is a novel GABAA receptor positive allosteric modulator intended for chronic oral dosing. We are currently conducting a placebo-
controlled Phase 2 clinical trial evaluating the safety and efficacy of SAGE-324 in the treatment of essential tremor, known as the KINETIC
Study. We expect to report topline data from this study in early 2021. If the results of the KINETIC Study support further development, we
expect to initiate additional development activities including the next placebo-controlled Phase 2 clinical trial of SAGE-324 in essential tremor
in late 2021 to explore dose and frequency, including potential formulations. We believe SAGE-324 also has potential for the treatment of a
number of other neurological conditions, including epilepsy and Parkinson’s disease.

We are jointly developing zuranolone and SAGE-324 in the U.S. with Biogen MA Inc., or BIMA, and Biogen International GmbH, or,

together with BIMA, Biogen, under a collaboration and license agreement, or the Biogen Collaboration Agreement, that became effective in
December 2020.  Under the Biogen Collaboration Agreement, we will also jointly commercialize products containing zuranolone, which we
refer to as Licensed 217 Products, and products containing SAGE-324, which we refer to as Licensed 324 Products, with Biogen in the U.S. if
our development efforts are successful.  We refer to Licensed 217 Products and Licensed 324 Products individually as a Product Class and
collectively as the Licensed Products.  In addition, we have granted Biogen sole rights to develop and commercialize the Licensed Products
outside the U.S., other than in Japan, Taiwan and South Korea, or the Existing Partner Territory, where we have granted rights to Shionogi &
Co., Ltd., or Shionogi, with respect to zuranolone. We refer to the territories outside the U.S.

1

 
 
 
 
to which Biogen has rights under the Biogen Collaboration Agreement with respect to the applicable Licensed Product as the Biogen Territory.

Our second area of focus for future clinical development is novel compounds that target the NMDA receptor. The first product candidate

selected for development from this program is SAGE-718, an oxysterol-based positive allosteric modulator of the NMDA receptor, which we
are exploring in certain cognition-related disorders associated with NMDA receptor dysfunction, including cognition dysfunction associated
with diseases such as Huntington’s disease, Parkinson’s disease and Alzheimer’s disease.  We are currently conducting a Phase 2a open-label
study of SAGE-718 evaluating patients with Parkinson’s disease cognitive dysfunction, known as the PARADIGM Study, and a Phase 2a open-
label clinical trial of SAGE-718 in patients with Alzheimer’s disease mild cognitive impairment and mild dementia, known as the LUMINARY
Study. We expect to report topline data from the PARADIGM Study in early 2021 and from the LUMINARY Study in late 2021. We plan to
initiate further development activities including a placebo-controlled Phase 2 clinical trial with SAGE-718 in late 2021 with the indication and
design to be informed by the results of these and earlier clinical trials.  

We have other compounds at earlier stages of development with a focus on both acute and chronic brain health disorders.  Our early-

stage GABAA modulators include SAGE-689, expected to begin Phase 1 development in 2021 as a potential intramuscular therapy for
disorders associated with acute GABA hypofunction, and SAGE-319, intended to be studied as an oral therapy for potential use in disorders of
social interaction. Our early-stage NMDA modulators include SAGE-904, in Phase 1 development as a potential oral therapy for disorders
associated with NMDA hypofunction, and SAGE-421, intended to be studied as a potential oral therapy for certain neurodevelopmental
disorders and cognitive recovery and rehabilitation. We expect to continue our work on allosteric modulation of the GABAA and NMDA
receptor systems in the brain. The GABAA and NMDA receptor systems are broadly accepted as impacting many psychiatric and neurological
disorders, spanning disorders of mood, seizure, cognition, anxiety, sleep, pain, and movement, among others. We believe that we may have the
opportunity to develop molecules from our internal portfolio with the goal of addressing a number of these disorders in the future. We believe
that we may also have the opportunity to use our scientific approach to explore targets beyond the GABAA and NMDA receptor systems and to
develop compounds in areas of unmet need outside of CNS.

Our Strategy

Our goal is to build a top-tier biopharmaceutical company that is the leader in developing and commercializing brain health therapies.

Our current focus is on building on our multi-franchise opportunities in depression, neurology, and neuropsychiatry. Key elements of our
strategy are to:

•

•

•

•

continue to advance Phase 3 clinical development and regulatory activities with respect to zuranolone in PPD and MDD, and
potentially advance zuranolone for other indications as part of our strategic collaboration with Biogen;

continue our commercialization efforts with respect to ZULRESSO in the treatment of PPD in the U.S., with a primary focus in
geographies that have existing, active ZULRESSO treating sites;

complete the ongoing KINETIC Study in essential tremor, and, if the results support further development, initiate additional
development activities including the next placebo-controlled Phase 2 clinical trial with SAGE-324 in essential tremor to explore
dose and frequency, including potential formulations, with potential future development in epilepsy, Parkinson’s disease, and
other neurological conditions, as part of our strategic collaboration with Biogen;

complete the ongoing Phase 2a open-label PARADIGM Study of patients with Parkinson’s disease cognitive dysfunction and
Phase 2a open-label LUMINARY Study of patients with Alzheimer’s disease mild cognitive impairment and mild dementia, and
initiate a planned placebo-controlled Phase 2 clinical trial with the indication and design to be determined based on results of
completed and ongoing SAGE-718 clinical trials;

2

 
 
 
 
 
 
•

•

•

•

•

•

•

•

•

•

support our collaboration with Biogen with respect to zuranolone and SAGE-324 in the U.S., and support Biogen’s development
of zuranolone and SAGE-324 in Biogen’s licensed territories outside the U.S. and Shionogi’s development of zuranolone in the
Existing Partner Territory;

advance SAGE-689 and SAGE-904 in Phase 1 clinical development, including conducting planned Phase 1 clinical trials;

continue our research and development efforts to evaluate the potential for our existing product candidates in the treatment of
additional indications or in new formulations;

identify new targets, and generate and test new compounds and product candidates, with a focus on indications where we believe
we can make well-informed, rapid go/no-go decisions, with the goal of developing a diversified portfolio of assets with
differentiated features;

prepare and file new drug applications, or NDAs, with the by the U.S. Food and Drug Administration, or FDA, and conduct pre-
launch activities with respect to any of our product candidates that have been successfully developed;

commercialize any product candidates for which we obtain regulatory approval, including the manufacture of commercial
supplies;

at the appropriate time, as our development efforts progress, add personnel, including personnel to support product development
and ongoing and future commercialization efforts;

evaluate the market potential and regulatory pathways for our product candidates beyond zuranolone and SAGE-324 in the
European Union, or EU, and other countries outside the U.S., and determine how best to move forward where and when it may
make business and strategic sense;

continue to build, maintain, defend, leverage, and expand our intellectual property portfolio, including by utilizing the strengths of
our proprietary chemistry platform and scientific know-how to expand our portfolio of new chemical entities to lessen our long-
term reliance on the success of any one program and to facilitate long-term growth; and

continue to explore opportunities to establish agreements or alliances with other pharmaceutical companies, at the appropriate
time, where we believe a collaboration will add significant value to our efforts, including through capabilities, infrastructure,
speed or financial contributions, or to acquire new compounds, product candidates or products if we believe such opportunities
will help us achieve our goals or meet other strategic objectives.

Understanding the Foundations of Our Approach

The CNS is composed of a vast and complex network of different structures and cell types, most of which serve, directly or indirectly, to
provide a means for the nervous system to signal or communicate with other nerve cells to regulate brain function. The cell type responsible for
this signaling is called a neuron. One way chemical or electrical signals exert their effects on neurons is by traveling across a physical gap
located between two neurons, called a synapse. Presynaptic neurons transmit signals whereas postsynaptic neurons react to the signals. The
human brain contains approximately 86 billion neurons, each having hundreds to tens of thousands of synapses to allow for this
communication. This process is essential to all things, from organ function, to movement, to memory and all behavioral
processes.  Neurotransmission is the process by which signaling molecules, called neurotransmitters, are released by a presynaptic neuron,
travel over the synaptic space and bind to and interact with receptors on a postsynaptic neuron. Depending on the nature of the neurotransmitter
and receptor, this interaction results in excitation, inhibition or modulation of the receiving neuron’s behavior.

We are currently focused on developing drugs based on selective allosteric modulation of neurotransmitter receptors in the CNS.
Allosteric modulators are a class of small molecules that interact at a site different from the site where neurotransmitters bind, and allow the
potential for fine-tuning of neuronal signals. We believe that nowhere in the body is it more important to maintain normal rhythms than in the
brain, and accordingly we believe that allosteric modulation approaches are well-suited for the treatment of diseases and disorders of the brain.

We utilize our proprietary chemistry capabilities to design and identify drugs that are allosteric modulators, and that have properties

targeted to the indications of interest. Our goal is to select for development compounds that we believe are capable of varying degrees of
desired activity rather than complete activation or inhibition of the receptor. Our current focus is on two critical CNS receptor systems: GABA
and NMDA. The GABA receptor family, which is recognized as the major inhibitory neurotransmitter in the CNS, mediates downstream
neurologic and bodily function in part via activation of GABAA receptors. GABAA receptors play a key role in regulating neuron excitability.
The NMDA-type receptors of the glutamate receptor system are a major excitatory receptor system in the CNS. NMDA receptors serve a
critical role in CNS-related activities. Dysfunction in these systems is implicated in a broad range of brain disorders.

Our proprietary chemistry platform is centered, as a starting point, on our knowledge of the chemical scaffolds of endogenous
neuroactive steroids that are allosteric modulators of GABAA or NMDA receptors. We have leveraged this platform to assemble a chemistry
portfolio of greater than 8,000 compounds. We believe our proprietary chemistry platform allows us to:

•

•

control important properties such as half-life, brain penetration and the types of receptors our drugs act upon, thereby modulating
either inhibition or excitation either acutely or chronically; and

create drugs that are designed to exert control over the intensity of receptor activation or deactivation, with the potential to hit
targets in the brain with more precision, with the goal of increased tolerability and fewer off-target side effects than current CNS
therapies or previous therapies that have failed in development.

We target diseases and disorders of the brain where we believe patient populations are easily identified, clinical endpoints are well-

defined, and development pathways are feasible.

Our Product Pipeline

The following table summarizes the status of our product and product candidate portfolio as of the filing date of this Annual Report.

ZULRESSO (Brexanolone) CIV Injection

Our first product, ZULRESSO, is a proprietary IV formulation of brexanolone. Brexanolone is chemically identical to allopregnanolone,

a naturally occurring neuroactive steroid that acts as a positive allosteric modulator of GABAA receptors.  In March 2019, the FDA approved
ZULRESSO for the treatment of PPD in adults.  We launched ZULRESSO commercially in the U.S. in June 2019, after completion of
controlled substance scheduling of brexanolone by the U.S. Drug Enforcement Administration, or DEA, and incorporation of the scheduling
into the FDA-approved label and other product information.  The DEA placed ZULRESSO into Schedule IV of the Controlled Substances Act,
or CSA. ZULRESSO is administered as a continuous infusion given over two and a half days. Because of the risk of serious harm resulting
from excessive sedation or sudden loss of consciousness during the ZULRESSO infusion, ZULRESSO must be administered in a medically-
supervised healthcare setting that has been certified under a Risk Evaluation and Mitigation Strategy, or REMS, program and meets the other
requirements of the REMS program, including requirements related to monitoring of the patient during the infusion. Patients who are
prescribed ZULRESSO are required to enroll in a registry which may allow us to compile additional information to further our understanding
of the risk of excessive sedation or sudden loss of consciousness during administration of ZULRESSO and management of the risk.  Given the
mode and setting of administration of ZULRESSO and the requirements of the REMS program, ZULRESSO has been administered to date
primarily to treat women with severe PPD, and we expect that to continue to be the case.  We estimate that about 20% to 30% of women
diagnosed with PPD fall into this category.  

PPD is one of the most common medical complications during and after pregnancy, and is characterized by depressive symptoms that
may occur during pregnancy or following childbirth up to 12 months.  PPD symptoms may include sadness and depressed mood; anxiety or
agitation; loss of interest in daily activities; changes in eating and sleeping habits; feeling overwhelmed; fatigue and decreased energy; inability
to concentrate; hypervigilance about the baby or lack of interest in the baby; and feelings of worthlessness, shame or guilt.  In the U.S.,
estimates of new mothers identified with PPD each year vary state-to-state from 9% to 23%, with an overall average of 13.2%.  Based on these
data,

5

 
 
 
 
we estimate that 500,000 or more women in the U.S. each year may experience PPD, and approximately 50% are formally diagnosed.  We
estimate that 20% to 30% of women diagnosed with PPD will experience severe symptoms.  PPD can lead to devastating consequences for a
woman and for her family.  Suicide is one of the leading causes of maternal death following childbirth.

ZULRESSO is the only pharmacological therapy specifically approved for PPD.  The current standard of care for PPD is comprised of

psychotherapy and, in women with moderate or severe PPD, the cautious use of pharmacological therapies such as selective serotonin reuptake
inhibitors, or SSRIs, and serotonin and norepinephrine reuptake inhibitors, or SNRIs.

Naturally occurring allopregnanolone is found at its highest levels in women during the third trimester of pregnancy, returning to normal

levels generally within 24 hours after giving birth.  Levels of allopregnanolone have been found to be lower in women with PPD than in
healthy women.  It may be that women with PPD are particularly sensitive to the rapid decline in allopregnanolone after birth, potentially
causing GABAA-system mediated mood disruption. These data led to our interest in evaluating allosteric modulators of the GABAA receptor
such as brexanolone and zuranolone in the treatment of PPD.

The approval of ZULRESSO in the U.S. was based on positive results from our HUMMINGBIRD Phase 3 clinical program, which was

comprised of two multicenter, randomized, double-blind, parallel-group, placebo-controlled, Phase 3 clinical trials designed to evaluate the
safety and effectiveness of brexanolone in women with PPD, with supportive evidence from a Phase 2 clinical trial of brexanolone in PPD.
Results from the HUMMINGBIRD Phase 3 clinical program were published in the September 22, 2018 issue of The Lancet.  

Zuranolone (SAGE-217)

Our next most advanced product candidate is zuranolone (SAGE-217), a novel oral compound that is currently in Phase 3 clinical
development in PPD and MDD.  Zuranolone is a neuroactive steroid that, like brexanolone, is a positive allosteric modulator of GABAA
receptors, targeting both synaptic and extrasynaptic GABAA receptors.  We also believe zuranolone has potential in other indications such as
treatment resistant depression, bipolar depression and generalized anxiety disorder. We are jointly developing zuranolone in the U.S. with
Biogen under the Biogen Collaboration Agreement that became effective in December 2020, and will jointly commercialize zuranolone in the
U.S. if our development efforts are successful and it is approved in the U.S.  The Biogen Collaboration Agreement covers any products
incorporating zuranolone.  We have granted Biogen sole rights to develop and commercialize the Licensed 217 Products outside the U.S., other
than in the Existing Partner Territory, where we have granted rights to Shionogi. The FDA has granted zuranolone Breakthrough Therapy
designation and Fast Track designation in the treatment of MDD.

MDD is a serious mental health disorder commonly characterized by symptoms of depressed mood and/or loss of interest in pleasurable

activities causing impairment in daily life. MDD is characterized by a period of depressive symptoms lasting at least two weeks and is
associated with changes in affect, cognition, and function. In typical depressive episodes, the person experiences depressed mood, loss of
interest and enjoyment, and reduced energy leading to diminished activity for at least two weeks. Many people with depression also suffer from
anxiety symptoms and medically unexplained somatic symptoms. A person with moderate or severe MDD will typically have difficulties
carrying out his or her usual work, school, domestic or social activities due to symptoms of depression.  Antidepressants are widely used in the
treatment of MDD, but many patients do not adequately respond to existing treatments.  According to estimates, more than 17 million adults in
the U.S. reported at least one major depressive episode in 2018. Among U.S. adults reporting at least one major depressive episode in 2018,
approximately 11.5 million (67%) had a diagnosis of MDD, 8.7 million were treated in the outpatient setting for depression; and 7 million
(80.8% of those treated) received pharmacotherapy. Research conducted during the COVID-19 pandemic reported a three- to four-fold increase
in symptoms of depression among adults in the U.S. between April and December of 2020 compared to previous years. Preclinical and clinical
evidence suggest the role of GABAA receptor dysfunction in depression.  Low GABA and allopregnanolone levels have been found in the
brain, cerebrospinal fluid and plasma of depressed patients.  

6

 
 
To date, we have completed three placebo-controlled clinical trials evaluating zuranolone 30 mg, two in MDD and one in PPD, the
results of which have been previously disclosed. Two of the trials evaluating zuranolone 30 mg – the PPD trial and one of the MDD trials – met
their primary endpoints, and the other MDD trial did not meet its primary endpoint. Following discussions with the FDA, we determined to
conduct three new Phase 3 clinical trials as part of our pivotal program for zuranolone in MDD and PPD:

•

•

•

a placebo-controlled trial evaluating a two-week course of zuranolone 50 mg in patients with MDD, with additional short-term
follow-up, known as the WATERFALL Study;

a placebo-controlled trial evaluating a two-week course of zuranolone 50 mg in women with PPD, with additional short-term
follow-up, known as the SKYLARK Study; and

a placebo-controlled trial evaluating a two-week course of zuranolone 50 mg, when co-initiated with a newly administered
standard antidepressant therapy, as an acute rapid response treatment in patients with MDD, with additional short-term follow-up,
known as the CORAL Study.

We initiated patient dosing in the WATERFALL Study and the SKYLARK Study in the second quarter of 2020 and initiated patient

dosing in the CORAL Study in the fourth quarter of 2020. Topline results from the WATERFALL Study are expected in the first half of 2021,
and topline results from the CORAL Study and SKYLARK Study are expected in late 2021.

We are also conducting an open-label Phase 3 clinical trial, known as the SHORELINE Study, evaluating the safety of as-needed repeat

treatment with zuranolone in which patients with MDD receive an initial two-week course of zuranolone and responders from the first cycle
are followed for up to one year and eligible to receive as-needed retreatment during the follow-up period.  The need for repeated dosing is
assessed every 14 days based on the results of a patient-reported Patient Health Questionnaire-9 score (≥10) and 17-item Hamilton Rating
Scale for Depression (HAMD-17) assessment (≥20). The protocol of the clinical trial requires a minimum of 56 days between zuranolone 14-
day courses, to allow for a maximum of five treatments during the follow-up period.  Enrollment of patients receiving the 30 mg dose in the
SHORELINE Study was completed in the third quarter of 2019.  In May 2020, we amended the SHORELINE protocol to allow currently
enrolled patients to receive retreatment with zuranolone 50 mg. Additionally, in the second quarter of 2020, we began enrolling a new cohort of
patients with MDD in the SHORELINE Study who receive zuranolone 50 mg from the outset of their enrollment in the trial.

In October 2020, we reported interim topline results from a July 2020 data cut of the ongoing SHORELINE Study. For the primary

endpoint of safety and tolerability, the analyzed data showed that zuranolone was generally well-tolerated in the 30 mg dose and among the
initial patients treated with the 50 mg dose. Adverse events reported in the trial during the period analyzed were generally consistent with
results seen in previous clinical trials of zuranolone, with the most common adverse events in the 30 mg cohort (observed in > 5% of subjects)
including somnolence, headache and dizziness. The overall incidence of adverse events declined in subsequent treatment courses of zuranolone
30 mg. Adverse events >5% of somnolence, dizziness, sedation, headache and tremor were observed to be more frequent in the 50 mg cohort,
but were similar in severity to the adverse events seen with patients receiving 30 mg doses. Most adverse events were mild or moderate. An
increase in level of intensity of somnolence and sedation was also noted at the 50 mg dose in patients who had previously received a 30 mg
dose. At the time of the data cut analysis, patients with a clinical response (decrease in HAMD-17 baseline score of ≥50%) at the end of the
initial 14-day course of zuranolone 30 mg used a mean number of 1.9 treatments per year. We plan to report comprehensive data from patients
receiving the 30 mg dose in mid-2021 and topline data from patients receiving the 50 mg dose in late 2021.

Shionogi has completed a Phase 1 clinical trial in Japan to evaluate the safety and tolerability of zuranolone in Japanese and Caucasian

subjects. In July 2020, Shionogi initiated a Phase 2 clinical trial with zuranolone in Japanese patients with MDD.

We may consider additional development opportunities for zuranolone as part of the Biogen collaboration.

7

 
 
 
 
 
 
 
SAGE-324

After zuranolone, our next most advanced development candidate is SAGE-324. SAGE-324 is a novel GABAA receptor positive

allosteric modulator intended for chronic oral dosing. We are currently conducting a placebo-controlled Phase 2 clinical trial evaluating the
safety and efficacy of SAGE-324 in the treatment of essential tremor, known as the KINETIC Study.

Essential tremor is a neurodegenerative condition characterized by rhythmic trembling most commonly of the upper limbs, including the

hands; the head, voice, legs or trunk may also be affected. Symptoms generally evolve over time, are persistent, and affect patients’ ability to
function independently. Essential tremor is the most common movement disorder, estimated to affect more than 6 million adults in the U.S.,
with increasing prevalence among patients 50 years and older. First-line treatments for essential tremor include β-adrenergic blocker
propranolol and anticonvulsant primidone.

We expect to report topline data from the KINETIC Study in early 2021. If the results of the KINETIC Study support further

development, we expect to initiate additional development activities including the next placebo-controlled Phase 2 clinical trial of SAGE-324
in essential tremor in late 2021 to explore dose and frequency, including potential formulations. We believe SAGE-324 also has potential for
the treatment of a number of other neurological conditions, including epilepsy and Parkinson’s disease.

We are jointly developing SAGE-324 in the U.S. with Biogen, and will jointly commercialize Licensed 324 Products with Biogen in the
U.S. if our development efforts are successful and it is approved in the U.S.  We have granted Biogen sole rights to develop and commercialize
SAGE-324 outside the U.S. We may consider additional development opportunities for SAGE-324 as part of our collaboration with Biogen.

SAGE-718

Our second area of focus is the development of novel compounds that target the NMDA receptor. The first product candidate selected for
development from this program is SAGE-718, an oxysterol-based positive allosteric modulator of the NMDA receptor, which we are exploring
in certain cognition-related disorders associated with NMDA receptor dysfunction, including cognition dysfunction associated with diseases
such as Huntington’s disease, Parkinson’s disease and Alzheimer’s disease. Examples of indications involving NMDA receptor dysfunction
also include certain types, aspects or subpopulations of a number of diseases such as depression, Alzheimer’s disease, attention deficit
hyperactivity disorder, schizophrenia, and neuropathic pain. Based on signals observed in measures of executive function relevant to core
cognitive decline in a Phase 1 clinical trial of patients with early Huntington’s disease and in similar measures during an earlier Phase 1 cohort
of healthy volunteers without Huntington’s disease, we initiated patient dosing in September 2020 in a Phase 2a open-label clinical trial of
SAGE-718 evaluating patients with Parkinson’s disease cognitive dysfunction, known as the PARADIGM Study, and commenced dosing in a
Phase 2a open-label clinical trial of SAGE-718 in patients with Alzheimer’s disease mild cognitive impairment and mild dementia, known as
the LUMINARY Study, in early 2021. We expect to report topline data from the PARADIGM Study in early 2021 and topline data from the
LUMINARY Study in late 2021. We plan to initiate further development activities including a placebo-controlled Phase 2 clinical trial with
SAGE-718 in late 2021 with the indication and design to be informed by the results of the previous and ongoing clinical trials.  

Further Exploration of GABAA and NMDA Receptors and New Areas of Interest

We expect to continue to focus our research and development efforts on allosteric modulation of the GABAA and NMDA receptor
systems in the brain.  Our second product candidate targeting the NMDA receptor, SAGE-904, is in development as a potential oral therapy for
disorders associated with NMDA hypofunction. We initiated a Phase 1 clinical trial of SAGE-904 in healthy volunteers in the third quarter of
2019 and expect to complete single ascending dose and multiple ascending dose Phase 1 clinical trials of SAGE-904 in 2021.  Our portfolio of
novel GABAA receptor positive allosteric modulators includes SAGE-689, a product candidate intended for intramuscular administration, for
which we have completed the non-clinical studies required to move into a Phase 1 clinical development program. We expect to initiate and
complete a single ascending dose Phase 1 clinical trial of SAGE-689 in 2021. We also have other compounds

8

 
 
 
 
 
at earlier stages of development with a focus on both acute and chronic brain health disorders, including SAGE-319, an extrasynaptic GABAA
receptor-preferring positive allosteric modulator that we plan to study for potential use as an oral therapy in treating disorders of social
interaction, and SAGE-421, an NMDA receptor positive allosteric modulator that we plan to study for potential use in neurodevelopmental
disorders and cognitive recovery and rehabilitation. The GABAA and NMDA receptor systems are broadly accepted as impacting many
psychiatric and neurological disorders, spanning disorders of mood, seizure, cognition, anxiety, sleep, pain, and movement among others. We
believe that we may have opportunities to develop molecules from our internal portfolio to address a number of these disorders in the future.
Our ability to identify and develop such novel brain health therapies is enabled by our proprietary chemistry platform that is centered, as a
starting point, on knowledge of the chemical scaffolds of certain endogenous neuroactive steroid compounds. We believe our knowledge of the
chemistry and activity of allosteric modulators allows us to efficiently design molecules with different characteristics.  This diversity enables us
to regulate important properties such as half-life, brain penetration and receptor pharmacology to develop product candidates that have the
potential for better selectivity, increased tolerability, and fewer off-target side effects than either current therapies or previous therapies which
have failed in development. We believe that we may also have the opportunity to use our scientific approach to explore targets beyond the
GABAA and NMDA receptor systems and to develop compounds in areas of unmet need outside of brain health disorders.

We believe our broad potential pipeline lessens our reliance on the success of any one program. We believe our ability to design and
develop novel molecules with distinct profiles and receptor subtype selectivity may also provide us with the option, if we choose, to potentially
partner certain assets with third parties who possess the development and commercialization capabilities to pursue these programs, like our
recent strategic collaboration with Biogen. We may also evaluate opportunities to acquire new compounds, product candidates or products from
other companies or from academic institutions if we believe such opportunities will help us achieve our goals or meet other strategic
objectives.

Manufacturing and Supply

We neither own nor operate, and currently have no plans to own or operate, any manufacturing facilities. We currently source all of our

clinical and non-clinical material supply through third party contract manufacturing organizations, or CMOs.  We have also sourced our
existing inventory of our proprietary formulation of ZULRESSO for commercial sale from CMOs, and intend to source all of our future
commercial supplies of ZULRESSO from CMOs.

We have long-term supply agreements with our CMOs with respect to ZULRESSO drug substance and drug product. We have an

inventory of ZULRESSO drug substance and drug product in place to help mitigate any potential supply risks.  All commercial supplies are
intended to be manufactured applying current Good Manufacturing Practices, or cGMP.

We have established relationships with several CMOs under which the CMOs manufacture clinical and non-clinical supplies of drug

substance and drug product for zuranolone, SAGE-324, SAGE-718 and other product candidates on a purchase order basis under master
service and quality agreements. All clinical supplies of drug substance and drug product are intended to be manufactured under cGMP. Starting
materials and key intermediates to support the production of these product candidates are manufactured by other CMOs. We do not currently
have arrangements in place for either long-term supply or redundant supply of drug substance or drug product for zuranolone, SAGE-324, or
SAGE-718. We intend to put a long-term supply agreement in place at the appropriate time for drug substance and drug product for each
product candidate, if development continues.  We plan to mitigate potential commercial supply risks for any products that are approved in the
future through inventory management and through exploring additional manufacturers to provide drug substance or drug product.

We continue to refine and scale up the manufacturing process for zuranolone to prepare for potential commercialization of zuranolone, if

an NDA is submitted and approved. We also intend to improve the manufacturing process for our other product candidates and manufacture
clinical supplies as development progresses.  We believe we currently have sufficient zuranolone drug substance on hand for our ongoing Phase
3 clinical trials.

9

 
 
ZULRESSO, zuranolone, SAGE-324 and SAGE-718 are small molecules isolated as stable crystalline solids. We believe the syntheses

of ZULRESSO, zuranolone, SAGE-324 and SAGE-718 are reliable and reproducible from readily available starting materials, and the
synthetic routes are amenable to large-scale manufacturing and do not require unusual equipment in the manufacturing process. We expect to
continue to identify and develop drug candidates that are amenable to cost-effective manufacturing at contract manufacturing facilities.

Sales and Marketing

Our first product, ZULRESSO, was made commercially available in the U.S. as a treatment for PPD in adults in June 2019.  Our
revenue from sales of ZULRESSO has been negatively impacted by significant barriers arising from the complex requirements for treatment
and, more recently, by the COVID-19 pandemic, and these factors are expected to continue to impact revenues negatively in the
future. ZULRESSO is administered as a continuous infusion given over two and a half days. Because of the risk of serious harm resulting from
excessive sedation or sudden loss of consciousness during the ZULRESSO infusion, ZULRESSO is approved for administration only in a
medically-supervised healthcare setting that has been certified under a REMS program and meets the other requirements of the REMS
program, including requirements related to monitoring of the patient during the infusion.  The actions required for a healthcare setting to be
ready and willing to treat women with PPD are complex and time-consuming.  These actions include becoming REMS-certified; achieving
formulary approvals; establishing protocols for administering ZULRESSO; and securing satisfactory reimbursement. Sites must often negotiate
reimbursement on a payor-by-payor basis under commercial coverage. The availability, terms and timing of coverage for ZULRESSO vary
from payor to payor, both for commercially insured patients and from state Medicaid systems, and we have encountered some states that
impose significant coverage restrictions or lengthy delays on reimbursement of ZULRESSO. As a result, certain healthcare settings will not
treat Medicaid patients with ZULRESSO even if they are active sites of care for ZULRESSO. These requirements have created significant
barriers to treatment for women with PPD.  We expect these barriers will continue to negatively impact ZULRESSO revenue growth.  

These barriers have been compounded by the COVID-19 pandemic.  The spread of COVID-19 in the U.S. has resulted in a significant

number of sites of care pausing treatment of new patients with ZULRESSO and potential new sites pausing site activation activities.  We
believe concerns about exposure to the virus have also caused a significant reduction in the number of women with PPD seeking treatment with
ZULRESSO and in physicians willing to prescribe it. Given the continuing concerns about the COVID-19 pandemic across the country, we
expect the significant adverse impact of the pandemic on ZULRESSO revenues to continue.  Specifically, we anticipate that the COVID-19
pandemic will continue to have an adverse impact on our results of operations from sales of ZULRESSO as pandemic-related restrictions are
expected to continue to be in effect for the foreseeable future.  The scope and timing of the expected negative impact of the COVID-19
pandemic will depend on, among other factors, the duration and severity of precautionary measures taken to curb the spread of COVID-19, the
length, location and frequency of surges or waves of COVID-19 cases and the timing and success of the roll-out of vaccines for COVID-19 and
any return to normal business operations across the U.S.  Given the continued fluidity of the COVID-19 pandemic, we cannot predict its course
or for how long and to what extent it will have an adverse impact on ZULRESSO sales.

In April 2020, we implemented a workforce reduction that primarily affected the ZULRESSO commercial operation and related support

functions, including eliminating the entirety of our salesforce at that time. While we remain committed to working with healthcare providers
and women with PPD seeking access to ZULRESSO and plan to continue to evaluate opportunities to raise awareness and help reduce hurdles
to appropriate treatment, our ongoing commercial efforts, including our small account management field-based team and a small number of
sales representatives, are primarily focused on geographies that have existing, active ZULRESSO treating sites.  We expect that this approach
to our commercial efforts may continue to substantially limit the revenue opportunity for ZULRESSO. Given the shift in focus of our
commercial efforts and the continued impact of the COVID-19 pandemic, the number of new healthcare settings that become treating sites for
ZULRESSO may be very limited for the foreseeable future.  We may also find that certain healthcare settings that have in the past been active
treating sites may not be willing to remain infusion-ready as a result of the complex requirements related to administration of ZULRESSO and
compliance with the REMS, related

10

 
 
limitations and restrictions, or because of actual or perceived difficulties obtaining satisfactory reimbursement or limitations on reimbursement
or for other reasons. Healthcare settings that are active sites may also limit capacity used for ZULRESSO infusions or continue to wait to gain
more experience with the clinical profile of ZULRESSO and to secure direct experience with reimbursement prior to increasing patient
intake.  Sage Central, our patient support center located in Raleigh, North Carolina, continues to provide a range of patient support resources to
assist women with PPD and their families in the ZULRESSO treatment journey. In addition, our commercialization infrastructure includes
capabilities in medical affairs, manufacturing, quality control, and compliance.

We expect that we will need additional sales and marketing capabilities in the U.S. if zuranolone, SAGE-324 or any of our other current

or future product candidates are successfully developed and approved.  Our resource needs in those areas may be substantial if the approved
product is primarily prescribed by primary care healthcare professionals as is the case, for example, with respect to the treatment of MDD, or
as the result of other needs specific to the product. As described above, we and Biogen have agreed as part of our collaboration that, if
zuranolone and SAGE-324 are successfully developed and approved, we will jointly commercialize the products in the U.S., including sharing
equally in sales and marketing activities and profits and losses in the U.S. If we obtain regulatory approval of such products, Biogen will book
sales of Licensed 217 Products and we will book sales of Licensed 324 Products. We have granted Biogen sole rights to commercialize the
Licensed Products outside the U.S., other than in the Existing Partner Territory with respect to zuranolone, where we have granted such rights
to Shionogi.

We have entered into several license agreements with respect to our product and clinical-stage product candidates, which are described

Licenses

below.  

CyDex Pharmaceuticals

In September 2015, we amended and restated our existing commercial license agreement with CyDex Pharmaceuticals, Inc., or CyDex.

Under the terms of the commercial license agreement, as amended and restated, CyDex has granted us an exclusive license to CyDex’s
Captisol drug formulation technology and related intellectual property for the manufacture of pharmaceutical products incorporating
brexanolone or SAGE-689, and the development and commercialization of the resulting products in the treatment, prevention or diagnosis of
any disease or symptom in humans or animals other than (i) the ocular treatment of any disease or condition with a formulation, including a
hormone; (ii) topical ocular treatment of inflammatory conditions; (iii) treatment and prophylaxis of fungal infections in humans; and (iv) any
ocular treatment for retinal degeneration.

Pursuant to the CyDex license, we are required during the term of the agreement to use commercially reasonable efforts to continue
active, diligent development of the licensed product, to seek regulatory approval of the licensed product and to commercialize the licensed
product following regulatory approval. We must deliver periodic progress reports to CyDex.

We are obligated to make milestone payments under the amended and restated license agreement with CyDex based on the achievement
of clinical development and regulatory milestones in the amount of up to $0.8 million in clinical milestones and up to $3.8 million in regulatory
milestones for each of the first two fields with respect to brexanolone; up to $1.3 million in clinical milestones and up to $8.5 million in
regulatory milestones for each of the third and fourth fields with respect to brexanolone; and up to $0.8 million in clinical milestones and up to
$1.8 million in regulatory milestones for one field with respect to SAGE-689. The CyDex license is perpetual until terminated. We may
terminate the CyDex agreement for convenience upon providing 180 days’ prior written notice to CyDex. Either party has the right to
terminate the agreement for failure to cure a material breach in the applicable cure period.  We pay royalties to CyDex on sales of

11

 
 
ZULRESSO, and will also be required to pay royalties on sales of SAGE-689, if successfully developed, in the low single digits based on
levels of net sales.

We are also party to a supply agreement with CyDex. Under the supply agreement, we are required to purchase all of our requirements

for Captisol with respect to brexanolone and SAGE-689 from CyDex, and CyDex is required to supply us with Captisol for such purposes,
subject to certain limitations.

University of California

In October 2013, we entered into a license agreement with The Regents of the University of California, or the Regents, which was
amended in May 2014. Pursuant to this agreement, and subject to certain rights of the U.S. government and rights retained by the Regents, the
Regents granted us a non-exclusive, non-transferable license under all personal property rights of the Regents covering the tangible personal
property in an investigational new drug, or IND, application package owned by the Regents, or the Data, and a specified quantity of cGMP
grade allopregnanolone, or the Material, to (i) use the Data for reference or incorporation in an IND for the use of the Material as a treatment of
status epilepticus, or SE, essential tremor and/or PPD and (ii) use the Material or modifications of the Material to develop a pharmaceutical
formulation for clinical trials for SE, essential tremor and/or PPD. The rights licensed to us are not sublicenseable.

Pursuant to this agreement, we are required to use commercially reasonable efforts to proceed with the development, manufacture and

sale of one or more products containing allopregnanolone, a derived product under the agreement, for the treatment of SE, essential tremor
and/or PPD. We are required to deliver written reports to the Regents describing our progress no later than 60 days subsequent to June 30 and
December 31 of each fiscal year.

This agreement required us to make up to $0.1 million in milestone payments in connection with the first derived product that met the

relevant milestones, all of which we have already paid. We must also pay royalties of less than 1% to the Regents on ZULRESSO and for each
other derived product, if any, for a period of 15 years following the first commercial sale of such derived product. This agreement will
terminate on the earlier to occur of (i) 27 years after the effective date or (ii) 15 years after the last-derived product is first commercially sold.
We may terminate this agreement early for convenience upon providing 60 days’ prior written notice to the Regents. The Regents may
terminate this agreement early in the event of material default, including failure to provide timely progress reports, after the applicable cure
period, or in the event of our bankruptcy. In the event of early termination of this agreement, we have the right to sell any partially made
derived products for a period of 120 days from the date of termination, but would not otherwise have rights after termination under the licensed
rights to make, have made, use, sell, have sold, offer for sale or import products containing allopregnanolone.

In June 2015, we entered into an exclusive license agreement with the Regents whereby we were granted an exclusive license to certain

patent rights related to the use of allopregnanolone to treat various diseases. In exchange for such license, we paid an upfront payment of
$50,000, and made annual maintenance fees of $15,000 until the calendar year following the first sale of ZULRESSO. We are obligated to
make milestone payments following the achievement of specified regulatory and sales milestones of up to $0.7 million and $2.0 million in the
aggregate, respectively. We pay royalties to the Regents at a low single digit percentage of net sales of ZULRESSO, subject to specified
minimum annual royalty amounts. Unless terminated by operation of law or by acts of the parties under the terms of the agreement, the license
agreement will terminate when the last-to-expire patents or last-to-be abandoned patent applications expire, whichever is later.

Collaboration and License Agreement with Biogen

On November 27, 2020, we entered into the Biogen Collaboration Agreement with Biogen for the development, manufacture and
commercialization of Licensed 217 Products and Licensed 324 Products. The Biogen Collaboration Agreement became effective on December
28, 2020, upon the receipt of clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

We and Biogen have agreed that we will jointly develop and commercialize the Licensed Products in the U.S., and that Biogen solely

will develop and commercialize the Licensed Products outside the U.S., except, with respect to the Licensed 217 Products, in the Existing
Partner Territory. Each of we and Biogen is obligated to use commercially reasonable efforts to develop at least one product in each Product
Class in the U.S., and Biogen is also obligated to use commercially reasonable efforts to develop at least one product in each Product Class in
the Biogen Territory. We and Biogen have agreed to share jointly in the performance of the activities under the Biogen Collaboration
Agreement in the U.S. and to share all costs for activities under the Biogen Collaboration Agreement solely for the U.S. equally. The Biogen
Collaboration Agreement provides that Biogen has sole responsibility and decision-making authority with respect to such activities in the
Biogen Territory. Biogen is solely responsible for all costs for activities under the Biogen Collaboration Agreement in the Biogen Territory. We
have an Opt-Out Right (as defined below) in the U.S. with respect to a Product Class.

We have granted to Biogen a non-transferable, sublicensable, except for certain specified exceptions, license to certain of our intellectual

property as needed to perform the activities under the Biogen Collaboration Agreement. Such license is co-exclusive with us in the U.S. and
exclusive, even as to us, in the Biogen Territory, subject to certain retained rights to allow us to exercise our rights and perform our obligations
under the Agreement and with respect to the Existing Partner Territory.

Our activities for the U.S. will be conducted pursuant to joint development plans agreed to by us and Biogen, on a Licensed Product-by-

Licensed Product basis, and overseen by a joint steering committee, or the JSC. The JSC shall be composed of an equal number of
representatives from each of us and Biogen.

Under the terms of the Biogen Collaboration Agreement, Biogen paid us an upfront payment of $875.0 million on December 31, 2020.

For so long as a Licensed Product is being sold in the U.S., we and Biogen will share in all operating profits and losses arising from such
Licensed Product (50 percent us and 50 percent Biogen). The Biogen Collaboration Agreement provides that Biogen will book sales of
Licensed 217 Products globally. We will book sales of Licensed 324 Products in the U.S. and Biogen will book sales of Licensed 324 Products
outside of the U.S., in each case if Licensed Products are successfully developed and approved.  We have the right to opt out of such profit- and
loss-sharing on a Product Class-by-Product Class basis in the U.S., or in each case, an Opt-Out Right. If we elect to exercise our Opt-Out Right
with respect to a Product Class, we have agreed to transition to Biogen applicable development and commercial activities for such Product
Class for the U.S., and Biogen has agreed to assume sole operational and financial responsibility for such activities.

The Biogen Collaboration Agreement provides for aggregate regulatory/commercial milestone payments from Biogen to us for
(i) Licensed 217 Products of up to $475.0 million and (ii) Licensed 324 Products of up to $520.0 million. It also provides for aggregate one-
time sales milestone payments from Biogen to us of (i) up to $300.0 million for each Product Class if we have not exercised our Opt-Out Right
with respect to such Product Class and (ii) up to $525.0 million for each Product Class if we have exercised our Opt-Out Right with respect to
such Product Class.

13

 
 
Biogen has also agreed to pay us tiered royalties based on net sales of the Licensed Products in the Biogen Territory of high-teens
to low-twenties percentages. If we have exercised our Opt-Out Right in the U.S. with respect to a Product Class, Biogen has agreed to pay us
specified royalties based on net sales of the Licensed Products of such Product Class. Royalty payments may be reduced in certain specified
customary circumstances.

During the term of the Biogen Collaboration Agreement, neither us nor Biogen nor any of our respective affiliates is permitted outside of
the Biogen Collaboration Agreement to directly or indirectly develop, manufacture, conduct medical affairs activities or commercialize certain
products in specified indications, or enter into agreements or arrangements with third parties to perform any of the above activities.

Unless earlier terminated, the Biogen Collaboration Agreement expires on a Licensed Product-by-Licensed Product and country-by-

country basis on the later of (i) in the Biogen Territory, the expiration of the royalty term for such Licensed Product in such country or (ii) in
the U.S., until the parties agree to permanently stop commercializing such Licensed Product. Biogen may terminate the Biogen Collaboration
Agreement for convenience in its entirety or on a Product Class-by-Product Class basis or as to a region by providing advance written notice.
Either us or Biogen may terminate the Biogen Collaboration Agreement (i) in the event of a material breach in whole or in part, by the other
party subject to a cure period and (ii) in the event of the insolvency of the other party, in each case subject to specified conditions.

In connection with the execution of the Biogen Collaboration Agreement, we and BIMA also entered into a stock purchase agreement,
or the Biogen Stock Purchase Agreement, for the sale and issuance of 6,241,473 shares of our common stock, or the Biogen Shares, to BIMA
at a price of $104.14 per share, a premium of 40% over the volume-weighted average share price for the 30 days ending on the day prior to
entry into the Biogen Stock Purchase Agreement, for an aggregate purchase price of $650.0 million. The sale of the Biogen Shares was
consummated on December 31, 2020.

We have granted BIMA specified demand and piggyback registration rights with respect to the Biogen Shares. The Biogen Stock
Purchase Agreement also includes standstill provisions, lock-up restrictions and a voting agreement with respect to the Biogen Shares.
Pursuant to the terms of the Biogen Stock Purchase Agreement, BIMA has agreed not to, and to cause its affiliates not to, directly or indirectly
acquire our securities, seek or propose a tender or exchange offer or merger between us and BIMA, solicit proxies or consents with respect to
any matter, or undertake other specified actions, in each case subject to specified conditions. The standstill restrictions terminate on the earliest
of (i) a specified regulatory milestone under the Biogen Collaboration Agreement, (ii) the date one year following the termination of the
Biogen Collaboration Agreement and (iii) December 28, 2027.

BIMA has also agreed not to, and to cause its affiliates not to, sell or transfer any of the Biogen Shares for a period of eighteen months

and to limit sales and transfers of the Shares for an additional eighteen month period, in each case subject to specified conditions and
exceptions.

Collaboration Agreement with Shionogi & Co., Ltd.

In June 2018, we entered into a collaboration agreement with Shionogi. Pursuant to this agreement, Shionogi will be responsible for all

clinical development, regulatory filings and commercialization of products containing zuranolone for the treatment of MDD and potentially
other indications in the Existing Partner Territory. Shionogi made an upfront payment of $90.0 million in 2018, and we will be eligible to
receive additional payments of up to $485.0 million if certain regulatory and commercial milestones are achieved by Shionogi.

14

 
 
Under the terms of the agreement, the potential future milestone payments include up to $70.0 million for the achievement of specified

regulatory milestones, up to $30.0 million for the achievement of specified commercialization milestones, and up to $385.0 million for the
achievement of specified net sales milestones. We will receive tiered royalties on sales of zuranolone in the Existing Partner Territory, if
development efforts are successful, with tiers averaging in the low to mid-twenty percent range, subject to other terms of the agreement. Due to
the uncertainty of pharmaceutical development and the high historical failure rates generally associated with drug development, we may not
receive any additional milestone payments or any royalty payments from Shionogi.

Shionogi has also granted us certain rights to co-promote zuranolone in Japan. As between us and Shionogi, we maintain exclusive
rights to develop and commercialize zuranolone outside of the Existing Partner Territory. The upfront cash payment and any payments for
milestones and royalties are non-refundable and non-creditable.

The agreement with Shionogi will terminate on a licensed product-by-licensed product basis on the date on which the royalty term has

expired in each country in Shionogi’s territory for such licensed product and will ultimately expire upon the expiration of the last-to-expire
royalty term. Shionogi may remove South Korea or Taiwan from the covered territories, for any reason or no reason upon 180 days’ prior
written notice. Shionogi may terminate the agreement in its entirety for any reason or no reason upon 180 days’ prior written notice. Shionogi
may also terminate the agreement in the event of a serious adverse event or a clinical failure upon 60 days’ written notice to us. Either party
may terminate this agreement early in the event of an uncured material breach within 180 days’ after notice is delivered to the other party.

Washington University

In November 2013, we entered into a license agreement with Washington University. Under this agreement, and subject to certain rights

of the U.S. government and rights retained by Washington University, Washington University granted to us an exclusive, worldwide license
under certain patent rights to make, have made, sell, and offer for sale, use and import products covered by certain of its patent rights.
Washington University’s rights in patent applications disclosing and claiming SAGE-689 are included in this license agreement. Under this
agreement, Washington University also granted us non-exclusive license under certain technical information and tangible research information
to use such technical information and/or tangible research information to make, have made, sell, offer for sale, use and import products that
embody or were made using a method or process covered in the technical information and/or tangible research information. The Washington
University license also grants us a right to sublicense our licensed rights to third parties, provided each sublicensee enters into a written
agreement with us with terms consistent with our agreement with Washington University. We must pay to Washington University a percentage
of the revenue we receive from sublicensing our rights under this agreement, initially in the mid-teens and decreasing to the mid-single digits
over time.

Pursuant to the Washington University license, we are required to use commercially reasonable efforts to continue active, diligent

development of licensed products and to use commercially reasonable efforts to manufacture, promote and sell licensed products throughout
the territory and in the field during the term of the agreement. We must deliver written reports to Washington University describing our
progress no later than January 31 of each calendar year.

We must pay to Washington University an annual maintenance fee until and including the year in which our first Phase 2 clinical trial is
initiated, and we must make up to $0.7 million and $0.5 million in clinical development and regulatory milestones, respectively, to Washington
University, for each licensed product, upon reaching certain milestones relating to the clinical development of our product candidates. The
license agreement also requires us to make low single-digit royalty payments to Washington University in connection with the sales of licensed
products if successfully developed and approved.

The Washington University agreement will expire on a licensed product-by-licensed product basis upon the later of (i) the last day that

at least one valid patent claim covering the licensed product exists, or (ii) the tenth anniversary of the day of the first commercial sale of the
licensed product. We may terminate the Washington University agreement early for convenience upon providing Washington University with
90 days’ written notice. Washington University may terminate this agreement early in the event of our failure to cure a material breach within
the applicable cure period or our

15

 
 
bankruptcy. In the event of early termination of this agreement before the expiration of the last to expire of the patent rights, we must
immediately discontinue manufacture, sale and distribution of any licensed products.

Intellectual Property

We strive to protect the proprietary know-how and technology that we believe is important to our business, including seeking and
maintaining patents intended to cover our product candidates and compositions, their methods of use and processes for their manufacture, and
any other aspects of inventions that are commercially important to the development of our business. We may also rely on trade secrets to
protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection. To protect our rights to
our proprietary know-how and technology, we require all employees, as well as our consultants and contract research organization, or CROs,
when feasible, to enter into agreements that generally require disclosure and assignment to us of ideas, developments, discoveries and
inventions made by these employees, consultants, and CROs in the course of their service to us.

We plan to continue to expand our intellectual property estate by filing patent applications directed to compositions, methods of use,

treatment and patient selection, formulations and manufacturing processes created or identified from our ongoing development of our product
candidates. Our success will depend on our ability to obtain and maintain patent and other proprietary protection for commercially important
technology, inventions and know-how related to our business; defend and enforce our patents; preserve the confidentiality of our trade secrets;
and operate without infringing the valid and enforceable patents and proprietary rights of third parties. We also rely on know-how, continuing
technological innovation and in-licensing opportunities to develop and maintain our proprietary position. We seek to obtain domestic and
international patent protection, and endeavor to promptly file patent applications for new commercially valuable inventions.

The patent positions of biopharmaceutical companies like us are generally uncertain and involve complex legal, scientific and factual
questions. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and patent scope
can be reinterpreted by the courts after issuance. Moreover, many jurisdictions, including the U.S., permit third parties to challenge issued
patents in administrative proceedings, which may result in further narrowing or even cancellation of patent claims. We cannot predict whether
the patent applications we are currently pursuing, or may in the future pursue, will issue as patents in any particular jurisdiction or whether the
claims of any issued patents will be enforceable or provide sufficient protection from competitors.

Because patent applications in the U.S. and certain other jurisdictions are maintained in secrecy for 18 months or potentially even longer,
and since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain of the priority
of inventions covered by our issued patents, our pending patent applications or of patent applications we may file in the future. Moreover, we
may have to participate in interference proceedings or derivation proceedings declared by the U.S. Patent and Trademark Office, or U.S. PTO,
or similar proceedings outside the U.S., to determine priority of invention.

Patents

We hold issued patents and pending patent applications in the U.S., and in certain foreign countries. Our intellectual property holdings

include, but are not limited to:

•

•

One issued U.S. patent, exclusively licensed to us, covering a method of using our proprietary brexanolone formulation to treat
PPD, which will expire in 2033, and one U.S. issued patent and one granted patent in Europe covering our proprietary formulation
of brexanolone;

Pending U.S. and foreign patent applications covering certain aspects of brexanolone, including courses of treatment, dosage
regimens, methods for manufacturing, and additional uses of the formulation of brexanolone to treat various brain health diseases
and disorders, including PPD;

16

 
 
 
 
•

•

•

•

One issued U.S. patent covering the composition of matter of zuranolone, two issued U.S. patents covering methods of using
zuranolone, and one granted European patent covering the composition of matter of zuranolone, each of which expires in April
2034, subject to any potential extensions; and pending U.S. and foreign patent applications covering zuranolone, uses of
zuranolone to treat various brain health diseases and disorders, and solid forms of zuranolone;

U.S. and foreign patent applications covering SAGE-324, SAGE-319, and many other modulators of the GABAA receptor and
uses of these compounds to treat various brain health diseases and disorders;

Two issued U.S. patents covering composition of matter and method of use of SAGE-689 which expire in December 2033, and
U.S. and foreign patent applications covering SAGE-689 and uses of SAGE-689 to treat various brain health diseases and
disorders. These patents and patent applications are co-owned with Washington University, and Sage has an exclusive license to
Washington University’s rights in these patents and patent applications; and

U.S. and foreign patents and patent applications covering SAGE-718 and many other modulators of the NMDA receptor, and uses
of these compounds to treat various brain health diseases and disorders.  

Patent Term

The base term of a U.S. patent is 20 years from the filing date of the earliest-filed non-provisional patent application from which the

patent claims priority. The term of a U.S. patent can be lengthened by patent term adjustment, which compensates the owner of the patent for
administrative delays at the U.S. PTO. In some cases, the term of a U.S. patent is shortened by terminal disclaimer that reduces its term to that
of an earlier-expiring patent.

17

 
 
 
 
 
 
The term of a U.S. patent may also be eligible for patent term extension under the Drug Price Competition and Patent Term Restoration

Act of 1984, referred to as the Hatch-Waxman Act, to account for at least some of the time the drug is under development and regulatory
review after the patent is granted. With regard to a drug for which FDA approval is the first permitted marketing of the active ingredient, the
Hatch-Waxman Act allows for extension of the term of one U.S. patent that includes at least one claim covering the composition of matter of
an FDA-approved drug, an FDA-approved method of treatment using the drug, and/or a method of manufacturing the FDA-approved drug. The
extended patent term cannot exceed the shorter of five years beyond the non-extended expiration of the patent or 14 years from the date of the
FDA approval of the drug. Some foreign jurisdictions, including Europe and Japan, also have patent term extension provisions, which allow for
extension of the term of a patent that covers a drug approved by the applicable foreign regulatory agency. In the future, if and when our
pharmaceutical products receive FDA approval, we expect to apply for patent term extension on patents covering those products, their methods
of use, and/or methods of manufacture.

Trade Secrets

In addition to patents, we may rely on trade secrets and know-how to develop and maintain our competitive position. Companies
typically rely on trade secrets to protect aspects of their business that are not amenable to, or that they do not consider appropriate for, patent
protection. We protect trade secrets, if any, and know-how by establishing confidentiality agreements and invention assignment agreements
with our employees, and, where feasible, with consultants, scientific advisors, contractors and certain other entities with whom we do business.
These agreements generally provide that all confidential information developed or made known during the course of an individual or entity’s
relationship with us must be kept confidential during and after the relationship. These agreements also generally provide that all relevant
inventions resulting from work performed for us or relating to our business and conceived or completed during the period of employment or
assignment, as applicable, shall be our exclusive property. In addition, we take other appropriate precautions, such as physical and
technological security measures, designed to guard against misappropriation of our proprietary information by third parties.

Competition

The biopharmaceuticals industry is highly competitive. There are many public and private companies, universities, governmental

agencies and other research organizations actively engaged in the research and development of products that may be similar to our product
candidates or address similar markets. It is probable that the number of companies seeking to develop products and therapies similar to our
products will increase.

Currently, there are no pharmacological therapies specifically approved for the treatment of PPD other than ZULRESSO.  The current

standard of care for PPD commonly consists of psychotherapy; however, patients with moderate or severe PPD are often prescribed
antidepressant medications such as SSRIs and SNRIs.  

Our most advanced development candidate, zuranolone, is in Phase 3 development for MDD and PPD.  Patients with MDD are typically
treated with a variety of antidepressant medications, including SSRIs and SNRIs. If successfully developed and approved, zuranolone may also
face competition from esketamine, which is approved in the treatment of treatment resistant depression. A number of companies are developing
product candidates intended for the treatment of MDD, including NMDA receptor antagonists or partial antagonists such as dextromethorphan/
bupropion. In November 2020, Axsome Therapeutics, Inc. announced that it expected to file its NDA for its NMDA receptor antagonist, AXS-
05, in January 2021.

In the field of neuroactive steroids focused specifically on modulation of GABAA receptors, we also face competition from a number of
companies, including Marinus Pharmaceuticals, Inc., or Marinus, and Praxis Precision Medicines, or Praxis.  Marinus is developing a form of
ganaxolone, a known GABAA positive allosteric modulator neuroactive steroid, that is in Phase 3 trials in patients with status epilepticus and
CDLK5 deficiency disorder. Praxis is developing PRAX-114, a GABAA receptor modulating neuroactive steroid, for MDD and is currently
reported as being in Phase 2/3 development.

18

 
 
SAGE-324, a novel GABAA receptor positive allosteric modulator, is in Phase 2 development in essential tremor. If successfully

developed and approved, SAGE-324 may face competition from a Phase 2b-ready T-type calcium channel modulator in development for
essential tremor by Jazz Pharmaceuticals, Inc.

A number of companies are working to develop products targeted at the NMDA receptor, both antagonists and agonists. Aptinyx Inc. has

multiple Phase 2 NMDA receptor modulators in development for multiple indications, including NYX-458 for the treatment of cognitive
impairment in Parkinson’s disease.

Many of our potential competitors, alone or with their strategic partners, have substantially greater financial, technical and human
resources than we do, and significantly greater experience in the discovery and development of product candidates, obtaining FDA and other
regulatory approvals of treatments and the commercialization of those treatments. Mergers and acquisitions in the biotechnology and
pharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors. We expect
competition in the indications we are pursuing will focus on efficacy, safety, convenience, availability, and price.  Our commercial opportunity
could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe
side effects, are more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA or other
regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a
strong market position before we are able to enter the market.

Government Regulation

Government authorities in the U.S. at the federal, state and local level and in other countries extensively regulate, among other things,

the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion,
advertising, distribution, post-approval monitoring/pharmacovigilance, safety and periodic reporting, marketing and export and import of drug
products. Generally, before a new drug can be marketed in a given jurisdiction, considerable data demonstrating its quality, safety and efficacy
must be obtained and/or generated, organized into a format specific to each regulatory authority, submitted for review and the drug must be
approved by the relevant regulatory authority or authorities.

U.S. Drug Development

In the U.S., the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and its implementing regulations.

Drugs 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, and local 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 a company to administrative or judicial sanctions. These sanctions could include, among other actions,
the FDA’s delay or refusal to approve pending applications, withdrawal of an approval, a clinical hold on a clinical investigation, warning or
untitled letters, 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 penalties or criminal prosecution. Any agency or judicial
enforcement action could have a material adverse effect on us.

Our product candidates must be approved by the FDA through the NDA process before they may be legally marketed in the U.S. The

process required by the FDA before a drug may be marketed in the U.S. requires substantial time, effort and financial resources and generally
involves the following:

•

•

Completion of extensive non-clinical studies and testing, sometimes referred to as non-clinical laboratory tests, non-clinical
animal studies and formulation studies, in accordance with applicable regulations, including the FDA’s current Good Laboratory
Practice, or GLP, regulations;

Submission to the FDA of an IND application, which must become effective before human clinical trials may begin;

19

 
 
 
 
•

•

•

•

•

•

•

Approval by an independent institutional review board, or IRB, or ethics committee representing each clinical trial site before
each trial may be initiated;

Performance of adequate and well-controlled human clinical trials in accordance with applicable IND and other clinical trial-
related regulations, sometimes collectively referred to as good clinical practice, or GCP, to establish the safety and efficacy of the
proposed drug for each proposed indication;

Submission to the FDA of an NDA for marketing approval of a new drug;

A determination by the FDA within 60 days of its receipt of an NDA to accept and file the NDA for review;

Satisfactory completion of a potential FDA pre-approval inspection of the manufacturing facility or facilities where the drug is
produced to assess compliance with cGMP requirements to assure that the facilities, methods and controls are adequate to
preserve the drug’s identity, strength, quality and purity;

Potential FDA audit of the non-clinical and/or clinical trial sites that generated the data in support of the NDA; and

Payment of applicable user fees and FDA review and approval of the NDA, including consideration of the views of any FDA
advisory committee, prior to any commercial marketing or sale of the drug in the U.S.

The data required to support an NDA are generated in two distinct development stages: non-clinical and clinical. For new chemical
entities, the non-clinical development stage generally involves synthesizing the active component, developing the formulation and determining
the manufacturing process, as well as carrying out non-human toxicology, pharmacology and drug metabolism studies in the laboratory, which
support subsequent clinical testing. Non-clinical tests include laboratory evaluation of product chemistry, formulation, stability and toxicity, as
well as animal studies to assess the characteristics and potential safety and efficacy of the product. The conduct of the non-clinical tests must
comply with federal laws and regulations, including, for animal studies, the Animal Welfare Act and GLP. The sponsor must submit the results
of the non-clinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed
clinical protocol, to the FDA as part of the IND.

An IND is a request for authorization from the FDA to administer an investigational drug product to humans. Some non-clinical testing
may continue even after the IND is submitted, but an IND must become effective before human clinical trials may begin. The central focus of
an IND submission is on the general investigational plan and the protocols for human trials. The IND automatically becomes effective 30 days
after receipt by the FDA, unless the FDA raises concerns or questions regarding the proposed clinical trials, including whether subjects will be
exposed to unreasonable health risks, and places the IND on clinical hold within that 30-day time period. In such a case, the IND sponsor and
the FDA must resolve any outstanding concerns before the clinical trial can begin. The FDA may also impose clinical holds on a drug
candidate at any time before or during clinical trials due to safety concerns or non-compliance. Accordingly, we cannot be sure that submission
of an IND will result in the FDA allowing clinical trials to begin, or that, once begun, issues will not arise that could cause the trial to be
suspended or terminated.

The clinical stage of development involves the administration of the drug candidate to healthy volunteers or to patients with the disease

or condition being studied under the supervision of qualified investigators, generally physicians not employed by or under the trial sponsor’s
control. Clinical trials must be conducted in accordance with GCPs, which establish standards for conducting, recording data from, and reporting
the results of, clinical trials, and are intended to assure that the data and reported results are credible and accurate, and that the rights, safety, and
well-being of study participants are protected. GCPs include the requirement that all research subjects provide their informed consent for their
participation in any given clinical trial. Clinical trials are conducted under protocols describing, among other details, the objectives of the
clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject safety and assess
efficacy. Each protocol, and any subsequent amendments to the protocol, must be submitted to the FDA as part of the IND. Further, each
clinical trial must be reviewed and approved by an IRB at or servicing each institution at which the clinical trial will be conducted. An IRB is
charged with protecting the welfare and rights of trial participants, and considers such items as whether the risks to individuals participating in
the clinical trials are minimized and are

20

 
 
 
 
 
 
 
 
 
reasonable in relation to anticipated benefits. The IRB also approves the informed consent form that must be provided to each clinical trial
subject or his or her legal representative and must monitor the clinical trial until completed. Companies sponsoring the clinical trials,
investigators, and IRBs also must comply with, as applicable, regulations and guidelines for obtaining informed consent from the study
patients, following the protocol and investigational plan, adequately monitoring the clinical trial, and timely reporting of adverse events. There
are also requirements governing the reporting of ongoing clinical trials and completed clinical trial results to public registries.

A sponsor who wishes to conduct a clinical trial outside the U.S. may, but need not, obtain FDA authorization to conduct the clinical
trial under an IND. Foreign studies conducted under an IND must meet the same requirements that apply to studies being conducted in the U.S.
If a foreign clinical trial is not conducted under an IND, the sponsor may submit data from the clinical trial to the FDA in support of an NDA
so long as the clinical trial is conducted in compliance with GCP, including review and approval by an independent ethics committee and
compliance with informed consent principles, and FDA is able to validate the data from the study through an onsite inspection if deemed
necessary.

Clinical Trials

Clinical trials are generally conducted in three phases that may overlap, known as Phase 1, Phase 2 and Phase 3 clinical trials.

•

•

•

Phase 1 clinical trials generally involve a small number of healthy volunteers who are initially exposed to a single dose and then
multiple doses of the product candidate. The primary purpose of these clinical trials is to assess the metabolism, pharmacologic
action, side effect tolerability and safety of the drug.

Phase 2 clinical trials typically involve studies in patients afflicted with the target disease to determine the dose required to
produce the desired benefits. At the same time, safety and further pharmacokinetic and pharmacodynamic information is
collected, as well as identification of possible adverse effects and safety risks and preliminary evaluation of efficacy.

Phase 3 clinical trials generally involve large numbers of patients afflicted with the target disease at multiple sites (typically from
several hundred to several thousand subjects), and are designed to provide the data necessary to demonstrate the effectiveness of
the product for its intended use, its safety in use, and to establish the overall benefit/risk relationship of the product and provide an
adequate basis for product approval and labeling. Phase 3 clinical trials may include comparisons with placebo and/or other
comparator treatments. The duration of treatment is often extended for drugs intended for chronic dosing to mimic the actual use
of a product during marketing.

Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These trials are

used to gain additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, FDA may mandate
the performance of Phase 4 clinical trials as a condition of approval of an NDA.

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and written IND safety reports
must be submitted to the FDA and the investigators for serious and unexpected suspected adverse events, increased rates of serious suspected
adverse events, or findings from other studies or from animal or in vitro testing that suggests a significant risk for human subjects. Phase 1,
Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. Success in one phase does not mean
that the results will be observed in subsequent phases. Each phase may involve multiple studies. If concerns arise about the safety of the
product candidate, the FDA or other regulatory authorities can stop clinical trials by placing them on a “clinical hold” pending receipt of
additional data, which can result in a delay or termination of a clinical development program. The sponsoring company, the FDA, or the IRB
may suspend or terminate a clinical trial at any time on various grounds, including a finding that the patients are being exposed to an
unacceptable health risk.

21

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

NDA and FDA Review Process

The results of non-clinical studies and of the clinical trials, together with other detailed information, including extensive manufacturing

information and information on the composition of the drug and proposed labeling, are submitted to the FDA in the form of an NDA requesting
approval to market the drug for one or more specified indications. The FDA reviews an NDA to determine, among other things, whether a drug
is safe and effective for its intended use and whether the product is being manufactured in accordance with cGMP to assure and preserve the
product’s identity, strength, quality and purity. FDA approval of an NDA must be obtained before a drug may be offered for sale in the U.S.

In addition, under the Pediatric Research Equity Act certain NDAs or supplements to an NDA must contain data to assess the safety and

efficacy of the drug 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. The FDA may grant deferrals for submission of pediatric data or full or
partial waivers. Under the Best Pharmaceuticals for Children Act, the FDA may also issue a Written Request asking a sponsor to conduct
pediatric studies related to a particular active moiety; if the sponsor agrees and meets certain requirements, the sponsor may be eligible to
receive additional marketing exclusivity for its drug product containing such active moiety.

Under the Prescription Drug User Fee Act, as amended, or PDUFA, each NDA must be accompanied by a user fee, unless subject to a

waiver. The FDA adjusts the PDUFA user fees on an annual basis. According to the FDA’s fee schedule, effective through September 30, 2021,
the user fee for an application requiring clinical data, such as an NDA, is approximately $2.87 million. PDUFA also imposes an annual
prescription drug program fee for human drugs of approximately $0.3 million. Fee waivers or reductions are available in certain circumstances,
including a waiver of the application fee for the first application filed by a small business. Additionally, no user fees are assessed on NDAs for
products designated as orphan drugs, unless the product also includes a non-orphan-designated indication.

The FDA reviews all NDAs submitted before it accepts them for filing, and may request additional information rather than accepting an
NDA for filing. The FDA must make a decision on accepting an NDA for filing within 60 days of receipt. Once the submission is accepted for
filing, the FDA begins an in-depth review of the NDA. Under the goals and policies agreed to by the FDA under PDUFA, the FDA aims to
complete its initial review of an NDA and respond to the applicant within 10 months from the filing date for a standard NDA and, and within
six months from the filing date for a priority NDA. The FDA does not always meet its PDUFA goal dates for standard and priority NDAs, and
the review process is often significantly extended by FDA requests for additional information or clarification.

After the NDA submission is accepted for filing, the FDA reviews the NDA 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 cGMP to assure and
preserve the product’s identity, strength, quality and purity. Before approving an NDA, the FDA will generally conduct a pre-approval
inspection of the manufacturing facilities for the new product to determine whether the facilities comply with cGMPs. The FDA will not
approve the product unless it determines that the

22

 
 
manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product
within required specifications. Before approving an NDA, the FDA may also audit data from clinical trials to ensure compliance with GCP
requirements and integrity of the data submitted in the NDA. Additionally, the FDA may refer applications for novel drug products or drug
products which present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other
experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. For
example, the advisory committee may recommend or the FDA may determine that a REMS program is necessary to ensure safe use of the
product. 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 the
applicant during the review process. The review and evaluation process for an NDA 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.

After the FDA evaluates an NDA, it may issue an approval letter or a Complete Response Letter. An approval letter authorizes

commercial marketing of the drug with specific prescribing information for specific indications. A Complete Response Letter indicates that the
review cycle of the application is complete and the application is not ready for approval. A Complete Response Letter usually describes all of
the specific deficiencies in the NDA identified by the FDA. The Complete Response Letter may require additional clinical data and/or one or
more additional pivotal Phase 3 clinical trials, and/or other significant and time-consuming requirements related to clinical trials, non-clinical
studies or manufacturing. If a Complete Response Letter is issued, the applicant may either resubmit the NDA, addressing all of the
deficiencies identified in the letter, or withdraw the application. Even if such additional data and information are submitted, the FDA may
ultimately decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical trials are not always conclusive, and the
FDA may interpret data differently than we interpret the same data.

There is no assurance that the FDA will ultimately approve a drug product for marketing in the U.S., 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
patient populations and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product.
Further, the FDA typically requires that certain contraindications, warnings or precautions be included in the product labeling, and may
condition the approval of the NDA on other changes to the proposed labeling, development of adequate controls and specifications, or a
commitment to conduct post-marketing testing or clinical trials and surveillance to monitor the effects of approved products. For example, the
FDA may require Phase 4 testing which may involve clinical trials designed to further assess a drug’s safety and/or efficacy 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 the FDA determines
that a REMS is 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. For example, the FDA has required a REMS for
ZULRESSO to mitigate the potential for harm associated with the risk of excessive sedation and loss of consciousness during the ZULRESSO
infusion.  As part of the REMS, administration of ZULRESSO is limited to certified healthcare settings that have been certified under a REMS
program under the supervision of qualified staff, and  patients who are prescribed ZULRESSO are required to enroll in a patient registry which
may allow us to compile additional information to further our understanding of the risk of serious harm resulting from excessive sedation or
sudden loss of consciousness during administration of ZULRESSO and management of the risk.  Any limitations on approval, marketing or use
for any of our products could restrict the commercial promotion, distribution, prescription or dispensing of those products. Product approvals
may be withdrawn for non-compliance with regulatory requirements if problems occur following launch, or if FDA determines that the product
is no longer safe or effective.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug product intended to treat a “rare disease or condition,”

which is generally a disease or condition that affects fewer than 200,000 individuals in the U.S., or

23

 
 
more than 200,000 individuals in the U.S., but for which there is no reasonable expectation that the cost of developing and making a drug
product available in the U.S. for this type of disease or condition will be recovered from sales of the product. If orphan product designation is
sought, it must be requested before submitting an NDA for the drug for the proposed rare disease or condition. If the FDA grants orphan drug
designation, the common name of the therapeutic agent and its designated orphan use are disclosed publicly by the FDA. Orphan product
designation does not, by itself, convey any advantage in or shorten the duration of the regulatory review and approval process.

If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such

designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other sponsors’ applications
to market the same drug for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to
the product with orphan exclusivity. Orphan exclusivity operates independently from other regulatory exclusivities and other protection against
generic competition, including patents that we hold for our products. A sponsor of a product application that has received an orphan drug
designation may also be granted tax incentives for clinical research undertaken to support the application. In addition, the FDA may coordinate
with the sponsor on research study design for an orphan drug and may exercise its discretion to grant marketing approval on the basis of more
limited product safety and efficacy data than would ordinarily be required, based on the limited size of the applicable patient population.

Competitors, however, may receive approval of different products for the indication for which the orphan product has exclusivity or
obtain approval for the same product but for a different indication than that for which the orphan product has exclusivity. Orphan product
exclusivity also could block the approval of one of our products for seven years if a competitor obtains approval of the same product as defined
by the FDA or if our product candidate is determined to be contained within the competitor’s product for the same indication or disease. If a
drug designated as an orphan product receives marketing approval for an indication broader than what is designated, it may not be entitled to
orphan product exclusivity. The FDA can revoke a product’s orphan drug exclusivity under certain circumstances, including when the holder of
the approved orphan drug application is unable to assure the availability of sufficient quantities of the drug to meet patient needs. Orphan drug
status in the EU has similar, but not identical, benefits.

Expedited Development and Review Programs

The FDA has several programs that are intended to expedite or facilitate the process for reviewing new drugs that are intended to treat a
serious or life-threatening condition and demonstrate the potential to address unmet medical needs for the condition and provides meaningful
therapeutic benefit over existing treatments. Fast Track designation and Breakthrough Therapy designation are two of these programs and
apply to the combination of the product and the specific indication for which it is being studied. The sponsor of a new drug or biologic may
request the FDA to designate the drug as a Fast Track product at any time during the development of the product and may request the FDA to
designate the drug as a Breakthrough Therapy based on preliminary clinical evidence which meet the criteria outlined in the FDA’s programs.
Under the Fast Track or Breakthrough Therapy expedited programs, the FDA may review sections of the marketing application on a rolling
basis before the complete NDA is submitted if the sponsor provides a schedule for the submission of the sections of the application, the FDA
agrees to accept sections of the application and determines that the schedule is acceptable, and the sponsor pays any required user fees upon
submission of the first section of the application.

Any product submitted to the FDA for marketing, including under a Fast Track or Breakthrough Therapy program, may be eligible for

other types of FDA programs intended to expedite development and review, such as priority review and accelerated approval.

Any product is eligible for priority review if it treats a serious condition and offers a significant improvement in the safety and
effectiveness of treatment, diagnosis or prevention compared to marketed products. Significant improvement may be shown by evidence of
increased effectiveness in the treatment of a condition, elimination or substantial reduction of a treatment-limiting product reaction,
documented enhancement of patient compliance that may lead to improvement in serious outcomes, and evidence of safety and effectiveness in
a new subpopulation. The FDA will attempt to direct additional resources to the evaluation of an application for a new drug designated for
priority review in an effort to

24

 
 
facilitate the review, and to shorten the FDA’s goal for taking action on a marketing application from ten months to six months from the date of
the NDA filing.

A product may also be eligible for accelerated approval if the product is intended to treat a serious or life-threatening illness and
provides meaningful therapeutic benefit over existing treatments.  Accelerated approval for a product means that it may be approved on the
basis of adequate and well-controlled clinical trials establishing that the product has an effect on a surrogate endpoint that is reasonably likely
to predict a clinical benefit, or on the basis of an effect on a clinical endpoint other than survival or irreversible morbidity. As a condition of
approval, the FDA may require that a sponsor of a drug receiving accelerated approval perform adequate and well-controlled post-marketing
clinical trials. If the FDA concludes that a drug shown to be effective can be safely used only if distribution or use is restricted, it will require
such post-marketing restrictions, as it deems necessary to assure safe use of the drug, such as:

•

•

distribution restricted to certain facilities or physicians with special training or experience; or

distribution conditioned on the performance of specified medical procedures.

The limitations imposed would be commensurate with the specific safety concerns presented by the drug. In addition, the FDA currently

requires as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the
commercial launch of the product.

Fast Track designation, priority review, accelerated approval and Breakthrough Therapy designation do not change the standards for

approval, but may expedite the development or approval process.

Pediatric Trials

The Food and Drug Administration Safety and Innovation Act, which was signed into law on July 9, 2012, amended the FDCA to
require that a sponsor who is planning to submit a marketing application for a drug that includes a new active ingredient, new indication, new
dosage form, new dosing regimen or new route of administration submit an initial Pediatric Study Plan, or PSP, within sixty days of an end-of-
Phase 2 meeting or as may be agreed between the sponsor and 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. 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 non-clinical studies, early phase clinical trials, and/or other clinical development programs. The FDA, if it learns of new
information, may also request that the sponsor amend the initial PSP.

Post-marketing Requirements

Following approval of a new product, a pharmaceutical company and the approved product are subject to continuing regulation by the

FDA, including, among other things, monitoring and recordkeeping activities, reporting to the applicable regulatory authorities of adverse
experiences with the product, providing the regulatory authorities with updated safety and efficacy information, product sampling and
distribution requirements, and complying with promotion and advertising requirements, which include, among others, standards for direct-to-
consumer advertising, restrictions on promoting drugs for uses or in patient populations that are not described in the drug’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 for off-label uses, manufacturers may not market or promote
such off-label uses. Prescription drug promotional materials must be submitted to the FDA in conjunction with their first use. Further, if there
are any modifications to the drug, including changes in indications, labeling, or manufacturing processes or facilities, the applicant may be
required to submit and obtain FDA approval of a new NDA or NDA supplement, which may require the applicant to develop additional data or
conduct additional non-clinical studies and clinical trials. As with new NDAs, the review process is often significantly extended by FDA
requests

25

 
 
 
 
for additional information or clarification. Any distribution of prescription drug products and pharmaceutical samples must comply with the
U.S. Prescription Drug Marketing Act and the Drug Supply Chain Security Act.

FDA regulations also require that approved products be manufactured in specific approved facilities and in accordance with cGMP. 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. NDA 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 manufacturers must comply with cGMP regulations that
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 manufacturers and other entities involved in the manufacture and
distribution of approved drugs are required to register their establishments with the FDA and certain state agencies, and are subject to periodic
unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must
continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. The discovery of
violative conditions, including failure to conform to cGMP, 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, including, among other things, recall or withdrawal of the
product from the market.

Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative

consequences, including adverse publicity, administrative enforcement, warning or untitled letters from the FDA, mandated corrective
advertising or communications with doctors, and civil penalties or criminal prosecution, 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
also 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.

Other Regulatory Matters

Manufacturing, sales, promotion and other activities following product approval are also subject to regulation by numerous regulatory
authorities in addition to the FDA, including, in the U.S., the Department of Health and Human Services; the U.S. Department of Justice; the
DEA; the Consumer Product Safety Commission; the Federal Trade Commission; the Occupational Safety and Health Administration; the
Environmental Protection Agency; and state and local governments.  

In the U.S., a drug product approved by the FDA may also be subject to regulation under the CSA as a controlled substance.  The CSA is

administered by the DEA and establishes, among other things, certain registration, security, recordkeeping, reporting, import, export and other
requirements for controlled substances.  The CSA classifies controlled substances into five schedules: Schedule I, II, III, IV or V.  FDA
approved pharmaceutical products may be listed in Schedule II, III, IV or V, with Schedule II substances considered to present the highest
potential for abuse or dependence and Schedule V substances the lowest relative risk of abuse among such substances.  An approved drug
product or drug candidate that has not yet been approved by the FDA may be subject to scheduling as a controlled substance under the CSA,
depending on the drug’s potential for abuse.  For a drug approved by the FDA and determined to require control under the CSA, the CSA
requires the DEA to issue an interim final order scheduling the drug within 90 days after the FDA approves the drug and the DEA receives a
scientific and medical evaluation and scheduling recommendation from the Department of Health and Human Services,  after it has been
completed by FDA.  FDA recommended, and DEA adopted, that brexanolone be scheduled as a schedule IV controlled substance.

In the U.S., arrangements and interactions with health care professionals, third-party payors, patients and others will expose us to
broadly applicable anti-fraud and abuse, anti-kickback, false claims and other health care laws and regulations.  These broadly applicable laws
and regulations may constrain the business or financial arrangements or

26

 
 
relationships through which we sell, market and distribute our approved product and any future products that may obtain marketing
approval.  In the U.S., federal and state health care laws and regulations that may affect our operations include:

•

•

•

The federal Anti-Kickback Statute, which makes it illegal for any person, including a company marketing a prescription drug (or a
party acting on its behalf) to knowingly and willfully solicit, receive, offer, or pay any remuneration (including any kickback,
bribe or rebate), directly or indirectly, in cash or in kind, that is intended to induce or reward the referral of an individual or
purchase, lease or order, or the arranging for or recommending the purchase or order, of a particular item or service, for which
payment may be made in whole or in part under a federal healthcare program, such as Medicare or Medicaid. This statute has been
interpreted to apply to arrangements between pharmaceutical companies on one hand and prescribers, patients, purchasers and
formulary managers on the other.  Liability under the Anti-Kickback Statute may be established without proving 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 federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal
civil False Claims Act. Although there are a number of statutory exemptions and regulatory safe harbors to the federal Anti-
Kickback Statute protecting certain common business arrangements and activities from prosecution or regulatory sanctions, the
exemptions and safe harbors are drawn narrowly. Practices that involve remuneration to those who prescribe, purchase, or
recommend pharmaceutical and biological products, including certain discounts, or engaging such individuals as consultants,
advisors, or speakers, may be subject to scrutiny if they do not fit squarely within an exemption or safe harbor. Our practices may
not in all cases meet all of the criteria for safe harbor protection from anti-kickback liability. Moreover, there are no safe harbors
for many common practices, such as educational and research grants, charitable donations, product support and patient
assistance.  Violations of this law may be punishable by up to ten years in prison, criminal fines, damages, administrative civil
money penalties, and the potential for exclusion from participation in federal healthcare programs.

The federal civil False Claims Act, which prohibits anyone from, among other things, knowingly presenting, or causing to be
presented claims for payment of government funds that are false or fraudulent, or knowingly making, using, or causing to be made
or used a false record or statement material to a false or fraudulent claim or knowingly and improperly avoiding, decreasing or
concealing an obligation to pay money to the federal government. Actions under the False Claims Act may be brought by the
federal government or as a qui tam action by a private individual in the name of the government.  Many pharmaceutical
manufacturers have been investigated and have reached substantial financial settlements with the federal government under the
civil False Claims Act for a variety of alleged improper activities.  The government may deem companies to have “caused” the
submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers or
promoting a product off-label. In addition, our activities relating to the reporting of prices used to calculate Medicaid rebate
information and other information affecting federal, state, and third-party reimbursement for our products, and the sale and
marketing of our products, are subject to scrutiny under this law. Penalties for a False Claims Act violation may include three
times the actual damages sustained by the government, plus significant civil penalties for each separate false or fraudulent claim,
and the potential for exclusion from participation in federal healthcare programs.

Numerous federal and state laws, including state data breach notification laws, state health information and/or genetic privacy
laws, and federal and state consumer protection laws  (e.g., Section 5 of the Federal Trade Commission Act and the California
Consumer Privacy Act), govern the collection, use, and disclosure and protection of health-related and other personal information.
Failure to comply with these laws and regulations could result in government enforcement actions and create liability, private
litigation, or adverse publicity.  In addition, we or our collaborators may obtain health information from third parties, such as
hospitals, healthcare professionals, and research institutions, that are subject to privacy and security requirements under the
federal Health Insurance Portability and Accountability Act of 1996, and its implementing regulations, or collectively,
HIPAA.  HIPAA imposes privacy and security obligations on covered entity health care providers, health plans, and health care
clearinghouses, as well as their “business associates” – independent contractors or agents of covered entities that receive or obtain
protected health information in connection with providing a service on behalf of a covered entity.  Although we are not directly
subject to the HIPAA information privacy and security provisions – other than with respect to providing certain employee benefits
– we could potentially be subject to criminal penalties if we or our agents knowingly obtain, use, or disclose individually
identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by

27

 
 
 
 
 
 
 
•

•

•

HIPAA.  In addition, HIPAA does not replace federal, state, or other laws that may grant individuals even greater privacy
protections.

The HIPAA fraud provisions, which impose criminal and civil liability for knowingly and willfully executing a scheme to defraud
any healthcare benefit program, including private third-party payors, and prohibit knowingly and willfully falsifying, concealing
or covering up a material fact or making any materially false, fictitious or fraudulent statement or representation, or making or
using any false writing or document knowing the same to contain any materially false fictitious or fraudulent statement or entry, in
connection with the delivery of or payment for healthcare benefits, items or services.

The federal Physician Payment Sunshine Act, being implemented as the Open Payments Program, which requires manufacturers
of drugs, devices, biologics, and medical supplies for which payment is available under Medicare, Medicaid or the Children’s
Health Insurance Program (with certain exceptions) to report annually to the Centers for Medicare and Medicaid Services, or
CMS, the agency that administers the Medicare and Medicaid programs, information related to direct or indirect payments and
other transfers of value to physicians and teaching hospitals, as well as ownership and investment interests held in the company by
physicians and their immediate family members. Beginning in 2022, applicable manufacturers also will be required to report
information regarding payments and transfers of value provided to physician assistants, nurse practitioners, clinical nurse
specialists, certified nurse anesthetists, and certified nurse-midwives.

Analogous state and local laws and regulations, such as state anti-kickback and false claims laws, which may apply to items or
services reimbursed under Medicaid and other state programs or, in several states, regardless of the payor. We also may become
subject to other state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary
compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise restrict
payments that may be made to healthcare providers; state laws that restrict the ability of manufacturers to offer co-pay support to
patients for certain prescription drugs; state laws that require drug manufacturers to report information related to clinical trials, or
information related to payments and other transfers of value to physicians and other healthcare providers or marketing
expenditures; state laws and local ordinances that require identification or licensing of sales representatives; and state laws
governing the privacy and security of health information in certain circumstances, many of which differ from each other in
significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Substantial resources are necessary to ensure that our business arrangements and interactions with health care professionals, third party

payors, patients and others comply with applicable health care laws and regulations. Although compliance programs can mitigate the risk of
investigation and prosecution for violations of these laws, the risks cannot be entirely eliminated. It is possible that governmental authorities
will conclude that our business practices do not comply with current or future statutes, regulations or case law, and if we are found to be in
violation of any of these laws or any other governmental regulations, we may be subject to significant civil, criminal and administrative
penalties, imprisonment, damages, fines, exclusion from government funded health care programs such as Medicare and Medicaid, or the
curtailment or restructuring of our operations. Any action against us for violation of these laws or regulations, even if we successfully defend
against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business.

Numerous other laws may apply to our products.  Pricing and rebate programs must comply with the Medicaid rebate requirements of

the U.S. Omnibus Budget Reconciliation Act of 1990 and more recent requirements in the Patient Protection and Affordable Care Act, as
amended by the Health Care and Education Reconciliation Act of 2010, collectively referred to herein as the ACA  (addressed further below in
the section on “U.S. Healthcare Reform”). If products are made available to authorized users of the Federal Supply Schedule of the General
Services Administration, additional laws and requirements apply. Many states impose various requirements on pharmaceutical manufacturers
to report development costs and pricing information when prices are increased. Penalties for late or faulty reporting can reach $10,000 per day.
Products must meet applicable child-resistant packaging requirements under the U.S. Poison

28

 
 
 
 
 
 
 
 
 
Prevention Packaging Act. Manufacturing, sales, promotion and other activities are also potentially subject to federal and state consumer
protection and unfair competition laws.

The handling of any controlled substances must comply with the CSA and Controlled Substances Import and Export Act.

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping,
licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products. The failure to comply with
any of these laws or regulatory requirements subjects firms to possible legal or regulatory action. Depending on the circumstances, failure to
meet applicable regulatory requirements can result in criminal prosecution, fines or other penalties, injunctions, issuance of warning or untitled
letters, recall or seizure of products, total or partial suspension of production, denial or withdrawal of product approvals, or refusal to allow a
firm to enter into supply contracts, including government contracts. Federal regulators, state attorneys general, and plaintiffs’ attorneys have
been and will likely continue to be active in this space. Any action against us for violation of these laws, even if we successfully defend against
it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. Prohibitions or
restrictions on sales or withdrawal of future products marketed by us could materially affect our business in an adverse way.

Many of these laws differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

Many of the state laws enable a state attorney general to bring actions and provide private rights of action to consumers as enforcement
mechanisms. There is also heightened sensitivity around certain types of health information, such as sensitive condition information or the
health information of minors, which may be subject to additional protections. Compliance with these laws is difficult, constantly evolving, and
time consuming. Changes in statutes, regulations or the interpretation of existing laws or 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 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.

U.S. Patent Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of the FDA approval of our drug candidates, if any, some of our U.S. patents may be
eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as
the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for
patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the
remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half
the time between the effective date of an IND and the submission date of an NDA, or the testing phase, plus the time between the submission
date of an NDA and the approval of that application, or the approval phase. This patent term restoration period may be reduced by the FDA if it
finds that applicant did not act with due diligence during the testing phase or the approval phase. Only one patent applicable to an approved
drug is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The U.S. PTO, in
consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, if circumstances
permit, we intend to apply for restoration of patent term for one of our then owned or licensed patents, if any, to add patent life beyond its
current expiration date, depending on the expected length of the clinical trials and other factors involved in the filing of the relevant NDA.
Even if, at the relevant time, we have a valid issued patent covering our product, we may not be granted an extension if we were, for example,
to fail to apply within applicable deadlines, to fail to apply prior to expiration of relevant patents or otherwise to fail to satisfy applicable
requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to
obtain patent term extension or restoration or the term of any such extension is less than we request, and we do not have any other exclusivity,
our competitors may obtain approval of competing products following our patent expiration and our ability to generate revenues could be
materially adversely affected.

29

 
 
Some of our products may also be entitled to certain non-patent-related data exclusivity under the FDCA. The FDCA provides a five-

year period of non-patent data exclusivity within the U.S. to the first applicant to obtain approval of an NDA for a new chemical entity, or
NCE. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is
the molecule or ion responsible for the action of the drug substance. During the exclusivity period, an abbreviated new drug application, or
ANDA, or a 505(b)(2) NDA may not be submitted by another company for another drug containing the same active moiety, regardless of
whether the drug is intended for the same indication as the original innovator drug or for another indication, where the applicant does not own
or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a
certification of patent invalidity or non-infringement to one of the patents listed with the FDA Orange Book by the innovator NDA holder. The
FDCA also provides three years of marketing exclusivity for a full NDA, or supplement to an existing NDA if new clinical investigations,
other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of
the application, for example, for new indications, dosages or strengths of an existing drug. Three-year exclusivity prevents the FDA from
approving ANDAs and 505(b)(2) applications that rely on the information that served as the basis of granting three-year exclusivity. This three-
year exclusivity covers only the modification for which the drug received approval on the basis of the new clinical investigations, and does not
prohibit the FDA from approving ANDAs for drugs containing the active agent for the original indication or condition of use. Five-year and
three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be
required to conduct or obtain a right of reference to all of the non-clinical studies and adequate and well-controlled clinical trials necessary to
demonstrate safety and efficacy. We have obtained NCE exclusivity for brexanolone, and plan to seek NCE exclusivity for our current and
future product candidates, if eligible.  

European Union Drug Development

In the European Economic Area, or EEA, our future products may also be subject to extensive regulatory requirements. As in the U.S.,
medicinal products can only be marketed if a marketing authorization from the competent regulatory authorities in the EU has been obtained.

Similar to the U.S., the various phases of non-clinical and clinical research in the EU are subject to significant regulatory controls.

Although the EU Clinical Trials Directive 2001/20/EC has sought to harmonize the EU clinical trials regulatory framework, setting out
common rules for the control and authorization of clinical trials in the EU, the EU Member States have transposed and applied the provisions
of the Directive in a manner that is often not uniform. This has led to variations in the rules governing the conduct of clinical trials in the
individual EU Member States. The EU legislator has, therefore, adopted Regulation (EU) No 536/2014, or the EU Clinical Trials Regulation.
The new EU Clinical Trials Regulation, which will repeal and replace the EU Clinical Trials Directive, introduces a complete overhaul of the
existing regulation of clinical trials for medicinal products in the EU, including a new coordinated procedure for authorization of clinical trials
that is reminiscent of the mutual recognition procedure for marketing authorization of medicinal products, and increased obligations on
sponsors to publish clinical trial results. The entry into application of the EU Clinical Trials Regulation has been delayed and is currently not
expected before 2021.

Clinical trials in the EU must currently be conducted in accordance with the requirements of the EU Clinical Trials Directive and
applicable good clinical practice standards, as implemented into national legislation by EU Member States. Under the current regime, before a
clinical trial can be initiated it must be approved in each EU Member State where there is a site at which the trial is to be conducted by two
distinct bodies: the National Competent Authority, or NCA, and one or more Ethics Committees, or ECs. Under the current regime all
suspected unexpected serious adverse reactions to the investigated drug that occur during the clinical trial have to be reported to the NCA and
ECs of the Member State where they occurred.

In the EU, pediatric data or an approved Pediatric Investigation Plan, or PIP, or waiver, is required to have been approved by the
European Medicines Agency, or EMA, prior to submission of a marketing authorization application to the EMA or the competent authorities of
the EU Member States. In some EU countries, we may also be required to have an approved PIP before we can begin enrolling pediatric
patients in a clinical trial.

European Union Drug Review and Approval and Post-marketing Requirements

In the EEA (which is comprised of 27 Member States of the EU plus Norway, Iceland and Liechtenstein), medicinal products can only
be commercialized after a related marketing authorization has been granted. Marketing authorization for medicinal products can be obtained
through several different procedures. These are through a centralized, mutual recognition procedure, decentralized procedure, or national
procedure (if marketing authorization is sought for a single EU Member State). The centralized procedure allows a company to submit a single
application to the EMA. If a related positive opinion is provided by the EMA, the European Commission will grant a centralized marketing
authorization that is valid in all EU Member States and three of the four European Free Trade Associations countries (Iceland, Liechtenstein
and Norway), all of whom make up the EEA.

The UK’s withdrawal from the EU on January 31, 2020, commonly referred to as Brexit, has created significant uncertainty concerning

the future relationship between the UK and the EU.  The impact of Brexit on the ongoing validity in the UK of current EU authorizations for
medicinal products, whether granted through the centralized procedure, decentralized procedure, or mutual recognition, and on the future
process for obtaining marketing authorization for pharmaceutical products manufactured or sold in the UK remains uncertain.

The EU centralized procedure is mandatory for certain types of products, such as biotechnology medicinal products, orphan medicinal

products, and medicinal products containing a new active substance indicated for the treatment of HIV, AIDS, cancer, neurodegenerative
disorders, diabetes, auto-immune and other immune dysfunctions and viral diseases. The centralized procedure is optional for products
containing a new active substance that is not yet authorized in the EEA, or for products that constitute a significant therapeutic, scientific or
technical innovation or for which grant of centralized marketing authorization is in the interest of patients in the EU.

The decentralized authorization procedure permits companies to file identical applications for authorization to several EU Member
States simultaneously for a medicinal product that has not yet been authorized in any EU Member State. The competent authorities of a single
EU Member State, the reference member state, is appointed to review the application and provide an assessment report. The competent
authorities of the other EU Member States, the concerned member states, are subsequently required to grant marketing authorization for their
territories on the basis of this assessment. The only exception to this is where an EU Member State considers that there are concerns of
potential serious risk to public health related to authorization of the product. In these circumstances, the matter is submitted to the Heads of
Medicines Agencies for review. The mutual recognition procedure allows companies that have a medicinal product already authorized in one
EU Member State to apply for this authorization to be recognized by the competent authorities in other EU Member States.

The maximum timeframe for the evaluation of a marketing authorization application in the EU is 210 days, not including clock stops

during which applicants respond to questions from the competent authority. The initial marketing authorization granted in the EU is valid for
five years. The authorization may be renewed and valid for an unlimited period unless the national competent authority or the European
Commission decides on justified grounds to proceed with one additional five-year renewal period. The renewal of a marketing authorization is
subject to a re-evaluation of the risk-benefit balance of the product by the national competent authorities or the EMA.

The holder of an EU marketing authorization for a medicinal product must also comply with the EU’s pharmacovigilance legislation.

This includes requirements to conduct pharmacovigilance, or the assessment and monitoring of the safety of medicinal products.

Various requirements apply to the manufacturing and placing on the EU market of medicinal products.  Manufacture of medicinal

products in the EU requires a manufacturing authorization, and import of medicinal products into the EU requires a manufacturing
authorization allowing for import. The manufacturing authorization holder must comply with various requirements set out in the applicable EU
laws, regulations and guidance. These requirements include compliance with EU cGMP standards when manufacturing medicinal products and
active pharmaceutical ingredients, or APIs, including the manufacture of APIs outside of the EU with the intention to import the APIs into the
EU. Similarly, the distribution of medicinal products within the EU is subject to compliance with the applicable EU laws, regulations and
guidelines, including the requirement to hold appropriate authorizations for distribution granted by the competent

31

 
 
authorities of the EU Member States. Marketing authorization holders and/or manufacturing authorization holders and/or distribution
authorization holders may be subject to civil, criminal or administrative sanctions, including suspension of manufacturing authorization, in case
of non-compliance with the EU or EU Member States’ requirements applicable to the manufacturing of medicinal products.

In the EU, the advertising and promotion of medicinal products are subject to EU Member States’ laws governing promotion of
medicinal products, interactions with physicians and other healthcare professionals, misleading and comparative advertising and unfair
commercial practices. For example, applicable laws require that promotional materials and advertising in relation to medicinal products comply
with the product’s Summary of Product Characteristics, or SmPC, as approved by the competent authorities in connection with a marketing
authorization approval.  The SmPC is the document that provides information to physicians concerning the safe and effective use of the
product. Promotional activity that does not comply with the SmPC is considered off-label and is prohibited in the EU. Breaches of the rules
governing the promotion of medicinal products in the EU could be penalized by civil, criminal or administrative sanctions, which may include
fines and imprisonment. These laws may further limit or restrict the advertising and promotion of medicinal products to the general public and
may also impose limitations on promotional activities with healthcare professionals.

European Union Regulatory Data Exclusivity

In the EU, innovative medicinal products that are subject to marketing authorization on the basis of a full dossier and do not fall within

the scope of the concept of global marketing authorization qualify for eight years of data exclusivity upon marketing authorization and an
additional two years of market exclusivity. The concept of global marketing authorization prevents the same marketing authorization holder or
members of the same group, or companies that have concluded tacit or explicit agreements concerning the marketing of the same medicinal
product, from obtaining separate data and market exclusivity periods for medicinal products that contain the same active substance. This data
exclusivity, if granted, prevents regulatory authorities in the EU from referencing the innovator’s data to assess a generic application or
biosimilar application for eight years from the date of authorization of the innovative product, after which a generic or biosimilar marketing
authorization application can be submitted, and the innovator’s data may be referenced. However, the generic product or biosimilar products
cannot be marketed in the EU for a further two years thereafter. The overall ten-year period may be extended for a further year 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.

European Union Orphan Designation and Exclusivity

In the EU, orphan drug designations are granted by the European Commission based on a scientific opinion by the EMA’s Committee for

Orphan Medicinal Products in relation to medicinal products that are intended for the diagnosis, prevention or treatment of life-threatening or
chronically debilitating conditions affecting not more than 5 in 10,000 persons in the EU and in relation to which there exists no satisfactory
method of diagnosis, prevention, or treatment (or the product would be a significant benefit to those affected). Additionally, designation is
granted for products intended for the diagnosis, prevention, or treatment of a life-threatening, seriously debilitating or serious and chronic
condition and when, without incentives, it is unlikely that sales of the drug in the EU would be sufficient to justify the necessary investment in
developing the medicinal product.

Orphan medicinal products are entitled to ten years of exclusivity in all EU Member States.  However, marketing authorization may be

granted to a similar medicinal product with the same orphan indication during the ten-year period with the consent of the marketing
authorization holder for the original orphan medicinal product or if the manufacturer of the original orphan medicinal product is unable to
supply sufficient quantities of the product. Marketing authorization may also be granted to a similar medicinal product with the same orphan
indication if the similar product is deemed safer, more effective or otherwise clinically superior to the original orphan medicinal product. The
period of market exclusivity may, in addition, be reduced to six years if it is established that the criteria for orphan designation are no longer
met, such as if

32

 
 
it can be demonstrated on the basis of available evidence that the original orphan medicinal product is sufficiently profitable not to justify
maintenance of market exclusivity.

In addition, grant of orphan designation by the European Commission also entitles the holder of this designation to financial incentives

such as reduction of fees or fee waivers. Orphan drug designation must be requested before submitting an application for marketing
authorization. Orphan drug designation does not, in itself, convey any advantage in, or shorten the duration of, the regulatory review and
authorization process.

European Union Data Protection

EU Member States and other jurisdictions where we may in the future operate have adopted data protection laws and regulations, which
impose significant compliance obligations. For example, the General Data Protection Regulation, or GDPR, which became applicable on May
25, 2018, replacing the EU Data Protection Directive, imposes strict obligations and restrictions on the ability to collect, analyze and transfer
personal data, including health data from clinical trials and adverse event reporting. Data protection authorities from the different EU Member
States may interpret the GDPR and applicable related national laws differently and impose requirements additional to those provided in the
GDPR. In addition, guidance on implementation and compliance practices may be updated or otherwise revised, which adds to the complexity
of processing personal data in the EEA.

Legal mechanisms to allow for the transfer of personal data from the EEA to the U.S. have been challenged in the European Court of

Justice. In 2016, the European Commission and the U.S. Department of Commerce put in place the EU U.S. “Privacy Shield,” which was
subsequently relied on by some U.S. companies to transfer data to the U.S. However, on July 16, 2020 the European Court of Justice ruled the
Privacy Shield to be invalid. As a result, companies may no longer rely on the Privacy Shield as a basis on which to transfer personal data from
the EU to the U.S. U.S.-based companies are permitted to rely on other authorized means and procedures to transfer personal data provided by
the GDPR. However, the most common authorized procedure to transfer personal data out of the EU, the European Commission’s Standard
Contractual Clauses may, as a result of the European Court of Justice’s judgement of July 16, 2020, also come under increased scrutiny.
Following the European Court of Justice’s ruling, the European Data Protection Board issued a statement providing among other things that it
is a primary responsibility of the exporter and the importer, when considering whether to rely on Standard Contractual Clauses to export data
from the EU to third countries, to ensure that these third countries maintain a level of protection that is essentially equivalent to that guaranteed
by the GDPR in light of the EU Charter of Human Rights. Companies may need to revise their Standard Contractual Clauses in light of the
July 16, 2020 judgement. Companies that have not taken steps to demonstrate that their Standard Contractual Clauses and personal data
recipients in the U.S. are suitable to transfer to receive the personal data may be subject to enforcement actions by competent authorities in the
EU for failure to comply with related data privacy rules.

In addition, the privacy and data security landscape in the EU continues to remain in flux. The EU-UK Trade and Cooperation
Agreement, which was signed on December 30, 2020, provides that personal data can continue to flow freely from the EEA to the UK for a
limited specified period of time. The agreement provides for a transition period of six months starting January 1, 2021. During this period
personal data may, in accordance with the requirements of the GDPR, flow from the EEA to the UK and from the UK to the EEA. If the
European Commission does not adopt an adequacy decision concerning the level of data protection in the UK within this six month period, any
potential flows of personal data between the EEA and the UK will subsequently be subject to the same restrictions as those imposed on other
third countries.

The GDPR has introduced additional data protection obligations that can have specific impact on the conduct of clinical trials in the
EEA. This includes obligations concerning the rights of patients in relation to their personal data collected during the clinical trials and the
need to conclude arrangements with clinical trials sites concerning data processing activities.

33

 
 
Rest of the World Regulation

For other countries outside of the U.S. and EU, such as countries in Eastern Europe, Latin America or Asia, the requirements governing
the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, the clinical trials must be
conducted in accordance with GCP requirements and the applicable regulatory requirements and the ethical principles that have their origin in
the Declaration of Helsinki.

Approval by a regulatory authority in one jurisdiction does not guarantee approval by comparable regulatory authorities in other
jurisdictions. If we fail to comply with applicable foreign regulatory requirements applicable to a given country, we may not be able to obtain
regulatory approval for our product candidates in such country if we choose to seek such approval, or we may be subject to, among other
things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal
prosecution.

Coverage and Reimbursement

U.S. Healthcare Reform

The containment of healthcare costs has become a priority of federal and state governments, and the prices of drugs have been a focus in

this effort. Changes in government legislation or regulation and changes in private third-party payors’ policies toward reimbursement for our
products, if successfully developed and approved, may reduce reimbursement of our products’ costs to physicians, pharmacies, patients, and
distributors. The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost-
containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic products. Adoption
of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures,
could limit our net revenue and results for products, if any, we commercialize in the future.

The pricing and reimbursement environment for our products may change in the future and become more challenging due to state and

federal healthcare reform measures. The American Recovery and Reinvestment Act of 2009, or ARRA, for example, allocated new federal
funding to compare the effectiveness of different treatments for the same condition. The plan for the research was published in 2012 by the
Department of Health and Human Services, 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 ARRA does not mandate the use of the
results of comparative effectiveness studies for reimbursement purposes, it is not clear what effect, if any, the research will have on the sales of
any products for which we receive marketing approval or on the reimbursement policies of public and private payors. It is possible that
comparative effectiveness research demonstrating benefits in a competitor’s product could adversely affect the sales of any product for which
we receive marketing approval. For example, if third-party payors find our products not to be cost-effective compared to other available
therapies, they may not cover our products 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 products on a profitable basis.

The ACA is a sweeping measure intended to expand healthcare coverage within the U.S., primarily through the imposition of health
insurance mandates on employers and individuals, the provision of subsidies to eligible individuals enrolled in plans offered on the health
insurance exchanges, and the expansion of the Medicaid program.  This law has substantially changed the way healthcare is financed by both
governmental and private insurers and has significantly impacted the pharmaceutical industry.  Changes that may affect our business include
those governing enrollment in federal healthcare programs, reimbursement changes, benefits for patients within a coverage gap in the Medicare
Part D prescription drug program (commonly known as the “donut hole”), rules regarding prescription drug benefits under the health insurance
exchanges, changes to the Medicaid Drug Rebate program, expansion of the Public Health Service Act’s 340B drug pricing program, or 340B
program, and fraud and abuse enforcement.  These changes have impacted previously existing government healthcare programs and have
resulted in the development of new programs, including Medicare payment for performance initiatives and improvements to the Medicare
physician quality reporting system and feedback program.  

34

 
 
One of the goals of ACA was to expand coverage for the uninsured while at the same time containing overall healthcare costs. With
regard to pharmaceutical products, among other things, the ACA increased minimum rebates a manufacturer must pay under the Medicaid
Drug Rebate Program and extended manufacturers’ Medicaid rebate liability to drugs dispensed to individuals who are enrolled in Medicaid
managed care organizations.  The ACA also requires manufacturers of drugs, devices, biologics, and medical supplies for which payment is
available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to CMS
information related to direct or indirect payments and other transfers of value to physicians and teaching hospitals, as well as ownership and
investment interests held in the company by physicians and their immediate family members. Beginning in 2022, applicable manufacturers also
will be required to report information regarding payments and transfers of value provided to physician assistants, nurse practitioners, clinical
nurse specialists, certified nurse anesthetists, and certified nurse-midwives. Failure to submit required information may result in civil monetary
penalties of $1,000 to $10,000 for each payment or ownership interest that is not timely, accurately, or completely reported (annual maximum
of $150,000), and $10,000 to $100,000 for each knowing failure to report (annual maximum of $1 million).

Some states have elected not to expand their Medicaid programs by raising the income limit to 133% of the federal poverty level, as is
permitted under the ACA.  For each state that does not choose to expand its Medicaid program, there may be fewer insured patients overall,
which could impact sales of our products that are approved and that we successfully commercialize, and our business and financial
condition.  Where Medicaid patients receive insurance coverage under any of the new options made available through the ACA, the possibility
exists that manufacturers may be required to pay Medicaid rebates on drugs used under these circumstances, a decision that could impact
manufacturer revenues.  

Certain provisions of the ACA have been subject to judicial challenges as well as efforts to repeal or replace them or to alter their

interpretation or implementation. For example, the U.S. Tax Cuts and Jobs Act of 2017, signed into law in December 2017, included a
provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on certain individuals who
fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” Currently, the
Supreme Court is considering whether the ACA’s individual mandate, is unconstitutional following the repeal of its associated tax penalty, and,
if so, whether the remaining provisions of the ACA are inseverable from the mandate; a ruling could produce any of a number of results,
including invalidation of the ACA in its entirety based on a finding of inseverability, and is expected by mid-2021. It is unclear how the
ultimate decision in this case, or other efforts to repeal, replace, or invalidate the ACA or its implementing regulations, or portions thereof, will
affect the ACA or our business. We expect that the ACA, its implementation, efforts to repeal or replace, or invalidate the ACA or portions
thereof, and other healthcare reform measures that may be adopted in the future, could have a material adverse effect on our industry generally
and on our ability to commercialize our product candidates, if approved.

Other legislative changes relating to reimbursement have been adopted in the U.S. since the ACA was enacted. For example, on August

2, 2011, the Budget Control Act of 2011, among other things, created the Joint Select Committee on Deficit Reduction to recommend to
Congress proposals for spending reductions. The Joint Select Committee did not achieve a targeted deficit reduction, which triggered the
legislation’s automatic reductions. In concert with subsequent legislation, this has resulted in aggregate reductions to Medicare payments to
providers of, on average, 2% per fiscal year through 2030 (with the exception of a temporary suspension from May 1, 2020 through March 31,
2021) unless Congress takes additional action. As long as these cuts remain in effect, they could adversely impact payment for any products we
may commercialize in the future. We expect that additional federal 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, and in turn could significantly reduce
the projected value of certain development projects and reduce our profitability.

Pharmaceutical Pricing and Reimbursement

Sales of ZULRESSO and any product candidates we successfully commercialize, if approved, in the future depend on the availability

and extent of coverage and reimbursement from third-party payors, which are increasingly reducing reimbursements for medical products and
services.  Decreases in third-party reimbursement for our products or a decision

35

 
 
 
by a third-party payor not to cover a product could reduce physician usage of our products and have a material adverse effect on our sales,
results of operations and financial condition.  In the U.S., healthcare providers are reimbursed for covered services and products through
Medicare, Medicaid, and other government healthcare programs, as well as through commercial insurance and managed healthcare
organizations. No uniform policy of coverage and reimbursement for drug products exists. Accordingly, decisions regarding the extent of
coverage and amount of reimbursement to be provided for any of our products will be made on a payor-by-payor basis. As a result, the
coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for
the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained.

We participate in the Medicaid Drug Rebate Program and other governmental programs.  The Medicaid Drug Rebate Program and other

governmental programs impose obligations to report certain pricing data to the federal government as well as other compliance obligations.
Other programs impose limits on the price we are permitted to charge certain entities for our products. Statutory and regulatory changes or
other agency action regarding these programs and their requirements could negatively affect the coverage and reimbursement by these
programs of our products for which we receive regulatory approval and could negatively impact our results of operations.

Under the Medicaid Drug Rebate Program, we are required to pay a rebate to each state Medicaid program for our covered outpatient

drugs that are dispensed to Medicaid beneficiaries and paid for by a state Medicaid program as a condition of having federal funds being
available for our drugs under Medicaid and Medicare Part B. Those rebates are based on pricing data we report on a monthly and quarterly
basis to CMS, the federal agency that administers the Medicare and Medicaid programs. These data include the average manufacturer price
and, in the case of innovator products, the best price for each drug, which, in general, represents the lowest price available from the
manufacturer to any wholesaler, retailer, provider, health maintenance organization, nonprofit entity, or governmental entity in the U.S. in any
pricing structure, calculated to include all sales and associated rebates, discounts, and other price concessions. The ACA (addressed further
above in the section on “U.S. Healthcare Reform”) made significant changes to the Medicaid Drug Rebate program, and CMS issued a final
regulation, which became effective on April 1, 2016, to implement the changes to the Medicaid Drug Rebate Program under the ACA.  On
December 31, 2020, CMS issued a final regulation that modified prior Medicaid Drug Rebate program regulations to permit reporting multiple
best price figures with regard to value‑based purchasing arrangements (beginning in 2022); provide definitions for “line extension,” “new
formulation,” and related terms, with the practical effect of expanding the scope of drugs considered to be line extensions that are subject to an
alternative rebate formula (beginning in 2022); and revise best price and average manufacturer price exclusions of manufacturer-sponsored
patient benefit programs, specifically regarding applicability of such exclusions in the context of pharmacy benefit manager “accumulator”
programs (beginning in 2023). It is currently unclear whether the Biden administration will delay or suspend implementation of this final rule.
Our failure to comply with these price reporting and rebate payment options could negatively impact our financial results.

Federal law requires that any company that participates in the Medicaid Drug Rebate Program also participate in the 340B drug pricing

program in order for federal funds to be available for the manufacturer’s drugs under Medicaid and Medicare Part B. The 340B program, which
is administered by the Health Resources and Services Administration, or HRSA, requires participating manufacturers to agree to charge
statutorily defined covered entities no more than the 340B “ceiling price” for the manufacturer’s covered outpatient drugs.  These 340B
covered entities include a variety of community health clinics and other entities that receive health services grants from the Public Health
Service, as well as hospitals that serve a disproportionate share of low-income patients. The ACA expanded the list of covered entities to
include certain free-standing cancer hospitals, critical access hospitals, rural referral centers and sole community hospitals, but exempts
“orphan drugs” from the ceiling price requirements for these covered entities.  The 340B ceiling price is calculated using a statutory formula,
which is based on the average manufacturer price and rebate amount for the covered outpatient drug as calculated under the Medicaid Drug
Rebate Program, and in general, products subject to Medicaid price reporting and rebate liability are also subject to the 340B ceiling price
calculation and discount requirement. Changes to the definition of average manufacturer price and the Medicaid Drug Rebate amount also
could affect our 340B ceiling price calculations and negatively impact our results of operations.

36

 
 
HRSA issued a final regulation regarding the calculation of the 340B ceiling price and the imposition of civil monetary penalties on
manufacturers that are found to have knowingly and intentionally overcharged covered entities, which became effective on January 1, 2019.  It
is currently unclear how HRSA will apply its enforcement authority under the regulation. We also are required to report our 340B ceiling prices
to HRSA on a quarterly basis, and HRSA then publishes them to covered entities.  Moreover, under a final regulation effective January 13,
2021, HRSA newly established an administrative dispute resolution, or ADR, process for claims by covered entities that a manufacturer has
engaged in overcharging, and by manufacturers that a covered entity violated the prohibitions against diversion or duplicate discounts. Such
claims are to be resolved through an ADR panel of government officials rendering a decision that could be appealed only in federal court. An
ADR proceeding could subject a manufacturer to onerous procedural requirements and result in additional liability.

Federal law also requires that a company that participates in the Medicaid Drug Rebate Program report average sales price information

each quarter to CMS for certain categories of drugs that are paid under the Medicare Part B program. Manufacturers calculate the average sales
price based on a statutorily defined formula as well as regulations and interpretations of the statute by CMS. CMS uses these submissions to
determine payment rates for drugs under Medicare Part B. Statutory or regulatory changes or CMS guidance could affect the average sales
price calculations for our approved products and the resulting Medicare payment rate, and could negatively impact our results of operations.
Also, the Medicare Part B drug payment methodology is subject to change based on legislation enacted by Congress.

Pricing and rebate calculations vary among products and programs. The calculations are complex and are often subject to interpretation

by us, governmental or regulatory agencies and the courts. The Medicaid rebate amount will be computed each quarter based on our
submission to CMS of our current average manufacturer prices and best prices for the quarter. If we become aware that our Medicaid reporting
for a prior period was incorrect, or has changed as a result of recalculation of the pricing data, we are obligated to resubmit the corrected data
for a period not to exceed three years from the period in which the data originally were due. Such restatements and recalculations would
increase our costs for complying with the laws and regulations governing the Medicaid Drug Rebate Program. Any corrections to our rebate
calculations could result in an overage or underage in our rebate liability for past quarters, depending on the nature of the correction. Price
recalculations also may affect the ceiling price at which we are required to offer our products to covered entities under the 340B program, and
may require us to issue refunds to 340B covered entities, which can be costly and burdensome.

We could be held liable for errors associated with our submission of pricing data. Civil monetary penalties can be applied if we are found

to have made a misrepresentation in the reporting of our average sales price for each misrepresentation and for each day in which the
misrepresentation was applied, or if we are found to have charged 340B covered entities more than the statutorily mandated ceiling price.  In
addition to retroactive rebates and the potential for 340B program refunds, if we are found to have knowingly submitted false average
manufacturer price or best price information to the government, we may be liable for significant civil monetary penalties per item of false
information. Our failure to submit monthly/quarterly average manufacturer price and best price data on a timely basis could result in a
significant civil monetary penalty per day for each day the information is late beyond the due date. Such failure also could be grounds for CMS
to terminate our Medicaid drug rebate agreement, pursuant to which we participate in the Medicaid program. In the event that CMS terminates
our rebate agreement, no federal payments would be available under Medicaid or Medicare Part B for our covered outpatient drugs.

CMS and the Office of Inspector General have pursued manufacturers that were alleged to have failed to report these data to the

government in a timely manner. Governmental agencies may also make changes in program interpretations, requirements or conditions of
participation, some of which may have implications for amounts previously estimated or paid. We cannot guarantee that our submissions will
not be found by CMS to be incomplete or incorrect.

In order to be eligible to have our products paid for with federal funds under the Medicaid and Medicare Part B programs and purchased

by the Department of Veterans Affairs, or VA, Department of Defense, or DoD, Public Health Service, and Coast Guard (collectively, the Big
Four agencies) and certain federal grantees, we are required to participate in the VA Federal Supply Schedule, or FSS, pricing program,
established under Section 603 of the Veterans Health Care

37

 
 
Act of 1992. Under this program, we are obligated to make our “covered” drugs (i.e., innovator drugs and biologics) available for procurement
on an FSS contract and charge a price to the Big Four agencies that is no higher than the Federal Ceiling Price, or FCP, which is a price
calculated pursuant to a statutory formula. The FCP is derived from a calculated price point called the “non-federal average manufacturer
price”, or Non-FAMP, which we are required to calculate and report to the VA on a quarterly and annual basis. Pursuant to applicable law,
knowing provision of false information in connection with a Non-FAMP filing can subject a manufacturer to significant civil monetary
penalties for each item of false information. The FSS contract also contains extensive disclosure and certification requirements.  In addition,
Section 703 of the National Defense Authorization Act for FY 2008, requires us to pay quarterly rebates to DoD on utilization of covered drugs
that are dispensed through DoD’s Tricare network pharmacies to Tricare beneficiaries. The rebates are calculated as the difference between the
annual Non-FAMP and FCP for the calendar year that the product was dispensed. If we overcharge the government in connection with the FSS
contract or Tricare Retail Pharmacy Rebate Program, whether due to a misstated FCP or otherwise, we will be required to refund the difference
to the government. Failure to make necessary disclosures and/or to identify contract overcharges can result in allegations against us under the
False Claims Act and other laws and regulations. Unexpected refunds to the government, and any response to government investigation or
enforcement action, would be expensive and time-consuming, and could have a material adverse effect on our business, financial condition,
results of operations and growth prospects.

In addition, in many 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 EU Member States have the power 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. An EU Member State may approve a specific price for the medicinal product or it may instead adopt a system of direct
or indirect controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that any
country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing
arrangements for any of our products, if approved. Historically, products launched in the EU do not follow price structures of the U.S., and
generally prices tend to be significantly lower.

In various EU Member States, we expect to be subject to continuous cost-cutting measures, such as lower maximum prices, lower or

lack of reimbursement coverage and incentives to use cheaper, usually generic, products as an alternative. Health Technology Assessment, or
HTA, of medicinal products is becoming an increasingly common part of the pricing and reimbursement procedures in some EU Member
States, including countries representing major markets. The HTA process, which is governed by the national laws of these countries, is the
procedure according to which the assessment of the public health impact, therapeutic impact and the economic and societal impact of use of a
given medicinal product in the national healthcare systems of the individual country is conducted. The outcome of HTA regarding specific
medicinal products will often influence the pricing and reimbursement status granted to these medicinal products by the competent authorities
of individual EU Member States. On January 31, 2018, the European Commission adopted a proposal for a regulation on health technologies
assessment. The proposal has not yet been adopted into law. This legislative proposal is intended to boost cooperation among EU Member
States in assessing health technologies, including new medicinal products, and providing the basis for cooperation at the EU level for joint
clinical assessments in these areas.

Employees and Human Capital

Our key human capital management objectives are to attract, retain and develop the highest quality talent. To support these objectives,
our human resources programs are designed to develop talent to prepare them for critical roles and leadership positions for the future; reward
and support employees through competitive pay and benefits; enhance our culture through efforts aimed at making the workplace more
engaging and inclusive; and acquire talent and facilitate internal talent mobility to create a high-performing and diverse workforce.

As of February 17, 2021, we employed 298 full-time employees, including 161 in research and development and 137 in selling, general

and administrative and no part-time employees. 44 of our employees hold M.D. or Ph.D. degrees. We have never had a work stoppage, and
none of our employees is represented by a labor organization or under any collective-bargaining arrangements. We consider our employee
relations to be good.

Item 1A. Risk Factors

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below, as well as the

other information in this Annual Report and in our other public filings before making an investment decision. Our business, prospects,
financial condition, or operating results could be harmed by any of these risks, as well as other risks not currently known to us or that we
currently consider immaterial. If any such risks or uncertainties actually occur, our business, financial condition or operating results could
differ materially from the plans, projections and other forward-looking statements included in this Annual Report, including in the foregoing
Business section and later in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and
elsewhere in this report and in our other public filings and public statements. The trading price of our common stock could decline due to any
of these risks, and as a result, our stockholders may lose all or part of their investment.

Risks Related to Product Development, Regulatory Approval and Commercialization

We may never be able to generate meaningful revenues from sales of ZULRESSO® (brexanolone) CIV injection at levels or on timing
necessary to support our investment and goals.

Our first product, ZULRESSO, was approved by the U.S. Food and Drug Administration, or FDA, in March 2019 as a treatment for
postpartum depression, or PPD, in adults, and was made commercially available in June 2019.  We may never be able to generate meaningful
revenues or revenues at levels or on timing necessary to support our investment and goals. Our revenue from sales of ZULRESSO has been
negatively impacted by significant barriers arising from the complex requirements for treatment and, more recently, by the rapid spread of
COVID-19 in the U.S., and these factors are expected to continue to impact revenues negatively in the future. 

ZULRESSO is administered as a continuous infusion given over two and a half days. Because of the risk of serious harm resulting

from excessive sedation or sudden loss of consciousness during the ZULRESSO infusion, ZULRESSO is approved for administration only in a
medically-supervised healthcare setting that has been certified under a Risk Evaluation and Mitigation Strategy, or REMS, program and meets
the other requirements of the REMS program, including requirements related to monitoring of the patient during the infusion.  The actions
required for a healthcare setting to be ready and willing to treat women with PPD are complex and time-consuming.  These actions include
becoming REMS-certified; achieving formulary approvals; establishing protocols for administering ZULRESSO; and securing satisfactory
reimbursement. Sites must often negotiate reimbursement on a payor-by-payor basis under commercial coverage.  These requirements have
created significant barriers to treatment for women with PPD.  We expect these barriers will continue to negatively impact ZULRESSO
revenue growth, but we do not know the extent of the anticipated impact.  The COVID-19 pandemic has compounded these barriers and further
impacted sales of ZULRESSO in the U.S. The spread of COVID-19 in the U.S. has resulted in a significant number of sites of care pausing
treatment of new patients with ZULRESSO and potential new sites pausing site activation activities.  We believe concerns about exposure to
the virus have also caused a significant reduction in the number of women with PPD seeking treatment with ZULRESSO and in physicians
willing to prescribe it. Given the ongoing nature of the pandemic across the country, we expect the significant adverse impact of the pandemic
on ZULRESSO revenues to continue for the foreseeable future. Given the continued fluidity of the pandemic situation, we cannot predict its
course or for how long and to what extent it will have an adverse impact on ZULRESSO sales.   

In April 2020, we implemented a workforce reduction that primarily affected the ZULRESSO commercial operation and related
support functions, including eliminating the entirety of our salesforce at that time. While we remain committed to working with healthcare
providers and women with PPD seeking access to ZULRESSO and plan to continue to evaluate opportunities to raise awareness and help
reduce hurdles to appropriate treatment, our ongoing commercial efforts, including our small account management field-based team and a
small number of sales representatives, are primarily focused on geographies that have existing, active ZULRESSO treating sites.  We expect
that this approach may continue to substantially limit the revenue opportunity for ZULRESSO, and may make it difficult for us to achieve
revenue growth and meet our revenue goals. Given this approach, the number of new healthcare settings that become treating sites for
ZULRESSO, if any, may also be limited.  We may also find that certain healthcare settings that have in the past been active treating sites may
not be willing to remain infusion-ready as a result of the complex requirements related to administration of ZULRESSO and compliance with
the REMS, related limitations and restrictions,

40

 
 
 
or because of actual or perceived difficulties obtaining satisfactory reimbursement or limitations on coverage and reimbursement or for other
reasons. Healthcare settings that are active treating sites may also limit capacity used for ZULRESSO infusions.

We may encounter other issues and challenges in commercializing ZULRESSO and generating revenues, including:

• Women with PPD who need treatment may find it too onerous to undergo an infusion or to be treated at a certified healthcare setting

overnight for the length of stay required for treatment, or to be enrolled in the registry or may be concerned about the risk of
excessive sedation and sudden loss of consciousness.

• We may never be able to generate sufficient data for the FDA to permit administration of ZULRESSO in the home setting, even with
monitoring and supervision requirements, and even if we were able to generate such data and obtain such approval, such approval
may not result in an increase in market acceptance of ZULRESSO or an increase in revenues.

• More healthcare providers than we expected have been unwilling to accept ZULRESSO as a treatment paradigm for women with
PPD and this could continue; we believe this unwillingness is due primarily to the product profile and reimbursement challenges
associated with ZULRESSO.  

• We may not be able to compete effectively with lower cost anti-depressants. 

•

Given the mode of administration, the nature of the REMS and the limitation on the administration of ZULRESSO to a medically-
supervised healthcare setting certified under the REMS, use of ZULRESSO in the U.S. has been focused primarily on women with
more severe symptoms of PPD, and we expect that to continue.  

• We may be unable to fully comply with our obligations under the ZULRESSO REMS, which include auditing of healthcare settings,

collection and analysis of required data, and other requirements, to the satisfaction of the FDA, or the FDA may require modifications
to or additional restrictions under the ZULRESSO REMS.

We may also continue to encounter challenges related to coverage and reimbursement of ZULRESSO.  These include restrictions

related to the severity of PPD cases for which ZULRESSO will be reimbursed, requirements that other treatments be used prior to
ZULRESSO, or other limitations in the scope, breadth, availability or amount of reimbursement covering ZULRESSO or the infusion. For
example, the availability, terms and timing of coverage for ZULRESSO by state Medicaid systems is expected to continue to vary significantly
by state, and we may encounter states that impose significant restrictions or lengthy delays. Similarly, certain healthcare settings or patients
may determine that the financial burdens of treatment are not acceptable. For example, a number of healthcare settings that are willing to
administer ZULRESSO to women with PPD who have commercial insurance do not currently treat Medicaid patients, which adversely affects
our ability to generate revenue from ZULRESSO.

Any of these issues could impair our ability to generate revenues or to meet our expectations with respect to the amount or timing of

revenues.  Any issues or hurdles related to our commercialization efforts may materially adversely affect our business, results of operations,
financial condition and prospects and could lead us to make significant further changes to the scope and nature of our efforts.  There is no
guarantee that we will be successful in our commercialization efforts with respect to ZULRESSO, or that we will be able to generate
meaningful revenues or revenues at the levels or on the timing necessary to support our investment and goals.  

Our future business prospects depend heavily on our ability, alone or through our collaborations, to successfully develop and gain
regulatory approval of our current product candidates, including zuranolone (SAGE-217), which is in Phase 3 clinical development for
major depressive disorder, or MDD, and PPD. We cannot be certain that we will be able to initiate planned clinical trials, to complete
ongoing clinical trials or to announce results of such trials, with respect to zuranolone or any of our other product candidates, on the
timelines we expect or at all or that the results of

41

 
 
 
 
 
 
 
 
 
our development programs will be positive or that the design or results of our programs will be sufficient to file for and gain regulatory
approval. We cannot be certain that we or our collaborators will be able to advance our product candidates into additional trials or to
successfully develop, obtain regulatory approval for, or successfully commercialize any of our current or future product candidates.

Drug development is a long, expensive and uncertain process, involving a high degree of risk.  Our business depends heavily on our

ability to complete clinical development and non-clinical studies of zuranolone and our other current product candidates, and to obtain
regulatory approval of and successfully commercialize those product candidates. Before obtaining regulatory approvals for the commercial sale
of any product candidate, non-clinical studies and clinical trials must demonstrate that the product candidate is safe and effective for use in
each target indication. We or our collaborators may not be able to demonstrate the efficacy and safety of zuranolone or any of our other current
product candidates or any future product candidate at each stage of clinical development or we may encounter issues with any non-clinical
studies required for regulatory submissions. Success in non-clinical studies or in earlier clinical trials or interim results of clinical trials may not
be repeated or observed in ongoing, future or completed studies or trials involving the same compound or other product candidates. Some or all
of our or our collaborators’ clinical trials may fail to meet their primary or key secondary endpoints, raise safety issues or generate mixed
results. For example, in December 2019, we announced that the MOUNTAIN Study, a Phase 3 clinical trial of zuranolone for the treatment of
MDD, did not meet its primary endpoint. The results of clinical trials or non-clinical studies of our product candidates at any stage may not
support further development or may not be sufficient to file for and obtain regulatory approval.  Even if we or our collaborators conduct the
trials required by or discussed with the FDA, the FDA may ultimately decide that the design, number and type of trials, number of patients
studied or results, even if positive, are not sufficient to file for or gain regulatory approval of zuranolone in MDD and PPD or of any of our
other product candidates in the indications we may study, or do not support the safety or efficacy or our intended profile for the product.  We
also may not be able to meet the requirements for non-clinical or clinical data needed to advance such a development program. We may find
that studying alternate formulations of our product candidates or doses that achieve higher or lower patient exposure may result in unexpected
adverse events or raise other safety issues or may otherwise generate negative results.  We are, for example, evaluating a 50 mg dose in our
ongoing pivotal Phase 3 clinical trials for zuranolone, which is expected to achieve higher patient exposures than previously observed in
patients enrolled in our prior multi-dose trials of zuranolone, and we are evaluating a higher dose in our Phase 2 clinical trial of SAGE-324 in
essential tremor, and we might decide to do so with other studies or programs in the future. In the case of zuranolone, we or our collaborators
may encounter issues with the efficacy or durability of short-term treatment, or co-initiated treatment with zuranolone and traditional
antidepressants, or safety and efficacy concerns with respect to retreatment that require additional studies be conducted or cause us not to
continue our efforts.  

Changes in formulation or the need to refine or scale-up the manufacturing process as we do for any of our product candidates could

also delay development or require us to conduct additional clinical trials or non-clinical studies or conduct post-approval analyses, or could
lead to different results than achieved with the earlier formulation or processes. We or our collaborators may not be able to initiate or complete
our clinical trials or announce results from our clinical trials on the timelines we expect. We or our collaborators may experience slower than
expected recruitment of sites or enrollment and randomization of patients in our clinical trials, particularly in clinical trials where an in-patient
stay or frequent site visits are required, the patient population is small, enrollment criteria are more selective than historically used or there are
existing therapies.   There is also the potential for slower than expected clinical site initiation, delays or problems in analyzing data, the
potential need for additional analysis or data or the need to enroll additional patients, or other unexpected issues such as adverse events in any
of our clinical trials. These types of delays or issues could lead to delays in the completion of a trial and announcement of results.  

The continuing COVID-19 pandemic in the U.S. and outside the U.S. may negatively impact our ongoing and planned development

activities. Concerns about COVID-19 and related precautions and restrictions may make it difficult to enroll patients in our clinical trials or
may increase the rates of patients withdrawing from our clinical trials following enrollment.  Some clinical sites may decline or delay
participation in our trials so as to prioritize medical resources to the treatment of COVID-19 patients or as a result of recommended or required
restrictions on nonessential businesses.  These concerns, precautions and restrictions arising from the COVID-19 pandemic may substantially
slow clinical site recruitment and initiation and enrollment in our clinical trials, or cause us to pause trials, in each case which may

42

 
 
significantly impact our ability to meet our expected timelines or may significantly impact our costs or other aspects of our business or cause us
to have to change our plans. For example, we have seen some slower recruitment in certain of our clinical trials, especially with respect to older
patients.

 In response to the COVID-19 pandemic or as a result of restrictions imposed or recommended by federal, state or local authorities,

we or our clinical sites have, in some cases, taken steps to help minimize the number of visits a clinical trial participant is required to make to a
site, including by limiting or modifying clinical trial procedures and visits for data collection.  Similarly, some clinical sites have imposed other
restrictions or limitations on key clinical trial activities such as restrictions related to monitoring of the sites by clinical research organizations.
  Some of these measures may continue or increase in the future depending on a number of factors, including the COVID-19 case rate in a
particular community, the timing of availability and extent of use of COVID-19 vaccines in the general population, and any adverse impact of
the evolving spread of variants of the virus that causes COVID-19.  Limitations or modifications to study procedures, study visits or data
collection, restrictions on key clinical trial activities such as monitoring or auditing, or other restrictions that may affect data analysis activities
may require additional assessment and evaluation from institutional review boards; negatively impact the integrity or completeness of our trial
data, the powering of a trial, the integrity or relevance of clinical study endpoints; or impact the timing of availability of results.  

The drug development process can take many years, and may include post-marketing studies and surveillance, which will require the

expenditure of substantial resources. Of the large number of drugs in development in the U.S., only a small percentage will successfully
complete the FDA regulatory approval process and will be commercialized.  Accordingly, even if we have the requisite financial resources,
when needed, to continue to fund our development efforts, we cannot assure you that any of our current or future product candidates will be
successfully developed or commercialized either in the U.S. or in any country outside the U.S.

Even if we or a collaborator of ours gain approval of any of our current or future product candidates, we may never be able to
successfully commercialize such new product or to meet our expectations with respect to revenues or profits from sales of such product.

ZULRESSO, our current or future product candidates and any future products, if successfully developed and approved, may cause
undesirable side effects that limit their commercial profile; delay or prevent further development or regulatory approval; cause regulatory
authorities to require labeling statements, such as boxed warnings or a REMS; or result in other negative consequences.

We may observe undesirable side effects or other potential safety issues in nonclinical studies or in clinical trials at any stage of
development of our product candidates.  Clinical trials by their nature utilize a sample of the potential patient population. With a limited
number of patients and limited duration of exposure, certain side effects of ZULRESSO, any current or future product candidates, or any future
products, if successfully developed and approved, may only be uncovered with a larger number of patients exposed to the product.  Those side
effects could be serious or life-threatening. If we or others identify undesirable side effects caused by ZULRESSO, any existing or future
product candidate or any future approved product:

•

•

•

regulatory authorities may withdraw or limit their approval of such products;

the FDA or regulatory authorities outside the U.S. may impose a clinical hold or partial clinical hold prior to the initiation of
development or during development of our product candidates which could cause us or our collaborators to have to stop, delay or
restrict further development; or we or our collaborators may, even without a clinical hold, decide to interrupt, delay or halt existing
non-clinical studies and clinical trials or stop development;

we may have difficulty enrolling patients in our clinical trials and completing such trials on the timelines we expect or at all, or we
may have to conduct additional non-clinical studies or clinical trials as part of a development program;

43

 
 
 
 
 
•

•

•

•

•

•

•

•

if a new drug application, or NDA, for any of our product candidates is reviewed by an advisory committee of the FDA, the advisory
committee may recommend against approval of the application or may recommend that the FDA require, as a condition of approval,
additional non-clinical studies or clinical trials, limitations on approved labeling or distribution and use restrictions, and the FDA may
ultimately agree with the recommendations of the advisory committee;

we or our collaborators may not be able ultimately to demonstrate, to the satisfaction of the FDA or other regulatory authorities, that
our product candidates are safe and that the benefits outweigh the safety risks, and the FDA or applicable foreign regulatory
authorities may not approve the product candidate;

regulatory authorities may require the addition of labeling statements, such as a boxed warning or additions to an existing boxed
warning, or a contraindication, including as a result of inclusion in a class of drugs for a particular disease, or may require a REMS,
or modifications to an existing REMS;

we or our collaborators may be required to change the way such products are distributed or administered, conduct post-approval
studies or change the labeling of the products;

we or our collaborators may be subject to regulatory investigations and government enforcement actions;

we or our collaborators may decide to remove such products from the marketplace;

we or our collaborators could be sued and held liable for injury caused to individuals exposed to or taking our products or product
candidates; and

our reputation may suffer.

We believe that any of these events could prevent us from achieving or maintaining market acceptance of the affected products, could

substantially increase the risks and costs of developing our product candidates or commercializing our products, and could significantly
adversely impact our ability and that of our collaborators to successfully develop and commercialize our current product candidates or future
products and generate revenues.

Obtaining regulatory approval to market any of our product candidates is a complex, lengthy, expensive and uncertain process, and the
FDA and regulatory authorities outside of the U.S. may delay, limit or deny approval of any of our product candidates for many
reasons.  Any setback or delay in obtaining regulatory approval for our product candidates or in our ability to commence marketing of our
products, if approved, may have a material adverse effect on our business and prospects.

We are not permitted to market any of our product candidates in the U.S. until we or our collaborators receive approval of an NDA from

the FDA or in any foreign countries until we or our collaborators receive the requisite marketing approval from such countries. Obtaining
approval of an NDA in the U.S. or marketing approval in any country outside the U.S. is a complex, lengthy, expensive and uncertain
process.  The FDA and regulatory authorities outside the U.S. may delay, limit or deny approval of any of our product candidates for many
reasons, including, among others:

•

•

we or our collaborators may not be able to demonstrate, to the satisfaction of the FDA or other regulatory authorities, that our product
candidates are safe and effective in any indication and that the benefits outweigh the safety risks;

the results of our non-clinical studies and clinical trials may be negative, or may not meet the level of statistical or clinical
significance required by the FDA or regulatory authorities outside the U.S. for marketing approval;

44

 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

•

•

•

•

•

•

•

the FDA or regulatory authorities outside the U.S. may impose a clinical hold or partial clinical hold prior to the initiation of
development or during development of our product candidates which could cause us to have to stop, delay or restrict further
development;

the FDA or regulatory authorities outside the U.S. may disagree with our interpretation of data from our non-clinical studies and
clinical trials, or may not accept data generated at one or more of our sites conducting non-clinical studies or clinical trials which may
cause the study or trial to fail;

the FDA or regulatory authorities outside the U.S. may determine that the number, design, size, conduct, implementation or result of
our non-clinical studies or clinical trials are inadequate for regulatory approval or that changes in dosing or drug formulation used in
our non-clinical studies or clinical trials require additional trials or studies, even if the regulatory authorities have previously reviewed
and commented on the design and details of our plans;

the FDA or regulatory or other government authorities outside the U.S. may require that we or our collaborators conduct additional
non-clinical studies and clinical trials prior to approval or post-approval;

the FDA or applicable foreign regulatory authorities may not approve the formulation, labeling or specifications of any of our product
candidates;

if an NDA for any of our product candidates is reviewed by an advisory committee of the FDA, the advisory committee may
recommend against approval of the application or may recommend that the FDA require, as a condition of approval, additional non-
clinical studies or clinical trials, limitations on approved labeling or distribution and use restrictions, and the FDA may ultimately
agree with the recommendations of the advisory committee;

the FDA or applicable foreign regulatory authorities may approve a product candidate for which we or our collaborators are seeking
regulatory approval for a more limited patient population than expected or with substantial use restrictions;

as was the case with ZULRESSO, the FDA may require a REMS as a condition of approval or post-approval for our product
candidates, or may modify an existing REMS;

the FDA or applicable foreign regulatory authorities may determine that the manufacturing processes or facilities of third-party
contract manufacturers with which we contract do not conform to applicable requirements, including current Good Manufacturing
Practices, or cGMPs; or

the FDA or applicable foreign regulatory agencies may change their approval policies or adopt new regulations.

Any of these factors, many of which are beyond our control, could jeopardize or delay our or our collaborators’ ability to obtain

regulatory approval for and successfully market our product candidates. Even if we or our collaborators receive marketing approval for any of
our product candidates, regulatory or other governmental authorities may still impose significant restrictions, including restrictions on the
indicated use or marketing, or may impose ongoing requirements for potentially costly post-approval studies. For example, the FDA has
imposed post-approval obligations in connection with approval of ZULRESSO.  We may not be able to fulfill these obligations in accordance
with the FDA’s timelines, or at all.  The FDA may recommend scheduling with respect to any of our current or future product candidates.  In
such event, as was the case with ZULRESSO, prior to a product launch, the U.S. Drug Enforcement Administration, or DEA, will need to
determine the controlled substance schedule of the product, taking into account the recommendation of the FDA.  The timing of the scheduling
process is uncertain and may delay our ability to market any product candidate that is successfully developed and approved.

45

 
 
 
 
 
 
 
 
 
 
 
 
Additionally, disruptions at the FDA and other agencies may 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, including the FDA, have had to furlough critical employees and stop critical activities.
If a prolonged government shutdown occurs in the future, 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.  

Fast Track and Breakthrough Therapy designations from the FDA or PRIority Medicines, or PRIME, designation from the European

Medicines Agency, or EMA, do not necessarily lead to a faster development pathway or regulatory review process, and do not increase the
likelihood of regulatory approval.  The FDA may withdraw Fast Track designation or Breakthrough Therapy designation, and the EMA may
withdraw PRIME designation, if the relevant agency believes that the designation is no longer supported by data from our clinical development
programs.

The COVID-19 pandemic has adversely impacted and may continue to adversely impact our business, including our sales of ZULRESSO
and our initiation, conduct and completion of non-clinical studies and clinical trials.

The COVID-19 pandemic in the U.S. has resulted in a significant number of sites of care pausing treatment of new patients with

ZULRESSO and potential new sites of care pausing site activation activities.  We believe concerns about exposure to the virus have also
caused a significant reduction in the number of women with PPD seeking treatment with ZULRESSO and in physicians willing to prescribe it.
Given continuing concerns about the COVID-19 pandemic across the country, we expect the significant adverse impact of the pandemic on
ZULRESSO revenues to continue. The scope and timing of the expected negative impact will depend on, among other factors, the duration and
severity of precautionary measures taken to curb the spread of COVID-19, the length, location and frequency of surges or waves of COVID-19
cases, the timing and extent of use of vaccines for the general population, the impact of the evolving variants of the virus that causes COVID-
19 and the timing and success of any return to normal business operations across the U.S.  We cannot predict for how long and to what extent
the COVID-19 pandemic will have an adverse impact on ZULRESSO sales.

As a result of the COVID-19 pandemic, we may also continue to experience delays or other disruptions that could negatively impact
our ongoing and planned development activities, including the timing of initiation and completion of non-clinical studies and clinical trials or
the integrity, completeness or usefulness of the data we collect in those studies or trials. These delays and disruptions may include:

•

•

•

•

delays or difficulties in recruiting clinical sites and in clinical site initiation, or the diversion of other healthcare resources and
personnel, due to prioritization of medical resources to the treatment of COVID-19 patients or as a result of recommended or required
precautions or limitations intended to curb the spread of the virus;  

delays or difficulties in enrolling patients in our clinical trials, or an increase in the number of patients who withdraw from our
clinical trials prior to completion as a result of concerns about COVID-19 or as a result of recommended or required precautions or
limitations intended to curb the spread of the virus, or the potential that patients in our trials may have or contract COVID-19 which
may impact the trial results;

delays or disruptions in non-clinical studies due to precautions taken by contract research organizations or other vendors in light of
the spread of COVID-19 or related restrictions recommended or imposed by federal, state or local authorities;

limitations or modifications to study procedures, the number and type of study visits or data collection or data analysis activities, or
other restrictions on other key clinical trial activities such as monitoring and auditing, in response to the COVID-19 pandemic or as a
result of restrictions imposed or recommended by federal, state or local governments;

46

 
 
 
 
 
 
 
 
•

•

•

interruption or delays in the operations of the FDA and comparable foreign regulatory agencies, which may impact timelines for
initiation of clinical trials, amendments of protocols, or inspections of manufacturing facilities;

interruption of, or delays in, availability of supplies of our product candidates if the COVID-19 pandemic continues in surges or
recurs in waves for an extended period, including the potential for shortages of raw materials, other drugs or materials used in our
clinical trials, including the standard antidepressant therapy being assessed in combination with zuranolone in the CORAL Study, or
staff available to our contract manufacturing organizations or other vendors in the supply chain or as the result of restrictions or
limitations in their businesses or activities; and

limitations on employee resources that would otherwise be focused on the conduct of our non-clinical studies and clinical trials,
including due to illness or working from home as a result of the COVID-19 pandemic.

The COVID-19 pandemic has also caused economic disruption, which could impair our business prospects.  Additionally, the

pandemic or the economic distributions from the pandemic may adversely impact the capital markets and make additional capital unavailable
to us on acceptable terms, or at all if we were to seek it.

The number of people with the diseases and disorders for which our products and product candidates are targeted may be smaller than we
expect or our other assumptions with respect to the potential markets for our products and product candidates may not be correct and the
markets may be significantly smaller than we expect.

Our lead product, ZULRESSO, has been approved in the U.S. for the treatment of PPD in adults. We are developing our product

candidate, zuranolone, for the treatment of MDD, PPD, and other potential indications. We are developing SAGE-324 as a potential oral
therapy for neurological conditions, such as essential tremor, epilepsy and Parkinson’s disease. We are exploring SAGE-718 as a potential
treatment for certain cognition-related disorders associated with NMDA receptor dysfunction, including cognitive dysfunction associated with
diseases such as Huntington’s disease, Parkinson’s disease and Alzheimer’s disease. There is no precise method of establishing the actual
number of patients with any of these disorders in any geography over any time period. With respect to PPD, MDD, essential tremor and many
of the other indications in which we are developing, or plan to develop, our product candidates, we estimate the prevalence of the disease or
disorder, and our estimates as to prevalence, including the assumptions we apply in determining our estimate, may not be accurate. In each
case, there is a range of estimates in the published literature and in marketing studies, which include estimates within the range that are lower
than our estimates. For example, our estimates of the prevalence of PPD are higher than estimates reported in some of the published literature
and results obtained from certain studies analyzing claims databases.  We believe these differences may be the result of variations in analytical
methodologies and possibly under-diagnosis of PPD as a result of lack of screening and under-reporting and some patients being reluctant to
seek treatment in clinical practice.  The actual number of patients with PPD, MDD, essential tremor or any other indication in which we elect
to pursue development of our product candidates may, however, be significantly lower than we believe. Even if our prevalence estimates are
correct, any approved product that we develop may only be indicated for or used by a subset of patients with the relevant disease or
disorder.  Our assumptions and estimates about the market for ZULRESSO and the potential market for our current and future product
candidates may not be accurate.  In the event the number of patients with the diseases and disorders we are studying is significantly lower than
we expect, we or our collaborators may have difficulties in enrolling patients in our clinical trials which may delay or prevent development of
our product candidates.  If our prevalence estimates with respect to any indication or our other market assumptions are not accurate, the
markets for any approved product for these indications may be smaller than we anticipate, which could limit our revenues and our ability to
achieve profitability or to meet our expectations with respect to the level and timing of revenues or profits.  

Positive results from non-clinical studies and clinical trials of our product candidates are not necessarily predictive of the results of later
non-clinical studies and clinical trials of our product candidates in the same indications or other indications. Interim results from non-
clinical studies and clinical trials may not be predictive of results of such non-

47

 
 
 
 
 
clinical studies or clinical trials once completed. If we cannot replicate the positive results from our earlier non-clinical studies and clinical
trials of our product candidates in our later non-clinical studies and clinical trials in the same indications or other indications, or we
cannot replicate our interim results in our completed non-clinical studies and clinical trials, we may be unable to successfully develop,
obtain regulatory approval for and commercialize our product candidates.

Positive results from non-clinical studies and clinical trials of our product candidates may not necessarily be predictive of the results

we or our collaborators may obtain from subsequent non-clinical studies or clinical trials using the same product candidate or other product
candidates. For example, unlike earlier trials of zuranolone in MDD and PPD, the Phase 3 MOUNTAIN Study evaluating zuranolone in
patients with MDD did not meet its primary endpoint. We or our collaborators may find that ongoing or future clinical trials of zuranolone or
any of our other product candidates may also fail to meet their primary endpoints. Similarly, we are studying brexanolone in the treatment of
advanced COVID-19-related acute respiratory distress syndrome, or ARDS, in a Phase 3 clinical trial based on our analysis of earlier
preclinical data and clinical data from a different indication.  There is no guarantee that brexanolone will be able to mitigate the morbidity and
mortality associated with advanced COVID-19-related ARDS.  Similarly, interim results from non-clinical studies and clinical trials may not
be predictive of results of a non-clinical study or clinical trial once completed.  

We or our collaborators may also observe safety issues in clinical trials or non-clinical studies of our product candidates that we or they
did not observe or appreciate in earlier stage clinical studies or non-clinical studies, or a different rate or severity of events, including as a result
of an increase in dosing, studying a different patient population or different indication than previously studied, or administering a product
candidate with a concomitant medication. For example, as part of ongoing clinical development efforts, we are currently evaluating a 50 mg
dose in our pivotal Phase 3 clinical trials for zuranolone.  This dose is expected to achieve higher patient exposures than those observed in
patients in earlier clinical trials of zuranolone. We are also evaluating a higher dose of SAGE-324 in our Phase 2 clinical trial in essential
tremor than we studied in our earlier exploratory study in this disease. These studies may result in unexpected adverse events or raise other
safety issues or may otherwise generate negative results.

The results from non-clinical animal models may not be replicated in clinical trials. Many product candidates, including many

targeting central nervous system disorders, with promising non-clinical profiles have failed to demonstrate similar safety, non-toxicity and
efficacy in humans.  

Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in later-stage clinical trials

after achieving positive results in earlier-stage development, and we cannot be certain that we will not face similar setbacks.  Many drugs have
failed to replicate efficacy and safety results in larger or more complex later stage trials. Moreover, non-clinical and clinical data are often
susceptible to varying interpretations and analyses, and many companies that believed their product candidates performed satisfactorily in non-
clinical studies and clinical trials nonetheless failed to obtain FDA approval. If we or our collaborators fail to produce positive results in our
ongoing and planned non-clinical studies or clinical trials of any of our product candidates, the development timeline and regulatory approval
and commercialization prospects for our product candidates, and, correspondingly, our business and financial prospects, would be materially
adversely affected.

Failures or delays in the commencement or completion of our ongoing and planned clinical trials of our current and future product
candidates could cause us not to meet our expected timelines or result in increased costs to us, and could delay, prevent or limit our ability
to gain regulatory approval of any such product candidate and to generate revenue from resulting products, if any.

Successful completion of clinical trials at each applicable stage of development is a prerequisite to submitting an NDA to the FDA or
equivalent filings outside the U.S. and, consequently, the ultimate approval and commercial marketing of any of our product candidates for the
indications in which we develop them. We do not know whether any of our ongoing clinical trials will be completed, and results announced, or
whether future trials will begin, as planned or expected, if at all, as the commencement and completion of clinical trials and announcement of
results can be delayed or prevented for a number of reasons, including, among others:

48

 
 
 
•

•

•

•

•

•

•

•

•

•

•

•

•

denial by the FDA or other regulatory authority of permission to proceed with our planned clinical trials or any other clinical trials we
may initiate, or placement of one or more clinical trials on full or partial clinical hold;

delay or inability to satisfy the requirements of the FDA to commence clinical trials, including chemistry, manufacturing and control,
or CMC, requirements, or to file or receive approvals of additional investigational new drug applications, or INDs, that may be
required;

negative or inconclusive results from our ongoing non-clinical studies or clinical trials;

challenges in identifying, recruiting, enrolling and retaining patients to participate in clinical trials;

the impact of the COVID-19 pandemic;

delays in reaching or failing to reach agreement on acceptable terms with prospective contract research organizations, or CROs, and
clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and
trial sites;

inadequate quantity or quality of supplies of a product candidate or other materials necessary to conduct clinical trials;

difficulties obtaining Institutional Review Board, or IRB, approval, and equivalent approval for sites outside the U.S., to conduct a
clinical trial at a prospective site or sites;

delays or problems in analyzing data, or the need for additional analysis or data or the need to enroll additional patients;

the occurrence of serious adverse events or unexpected drug-related side effects experienced by patients in a clinical trial or
unexpected results in ongoing non-clinical studies;

delays in validating endpoints utilized in a clinical trial;

the FDA or applicable regulatory authorities outside the U.S. disagreeing with our clinical trial design and our interpretation of data
from clinical trials, or changing the requirements for approval even after the regulatory authority has reviewed and commented on the
design for our clinical trials; and

reports from non-clinical or clinical testing of other therapies that raise safety or efficacy concerns.

In addition, a clinical trial may be suspended or terminated by us, the FDA or other regulatory authorities, the IRB or Ethics Committee,

or EC, at the sites where the IRBs or ECs are overseeing a clinical trial, or recommended for termination or suspension by a data and safety
monitoring board overseeing the clinical trial at issue or other regulatory authorities due to a number of factors, including, among others:

•

•

•

failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols;

inspection of the clinical trial operations or trial sites by the FDA or other regulatory authorities that reveals deficiencies or violations
that require us to undertake corrective action, including the imposition of a partial or full clinical hold;

unforeseen safety issues, including any that could be identified in our ongoing non-clinical studies, or adverse side effects or lack of
effectiveness identified in ongoing clinical trials;

49

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

changes in government regulations or administrative actions; and

problems with clinical supply materials.

Additionally, changes in regulatory requirements or guidance or unanticipated events during our non-clinical studies and clinical trials

may force us or our collaborators to amend non-clinical studies and clinical trial protocols or the applicable regulatory authorities may impose
additional non-clinical studies and clinical trial requirements. Amendments or changes to clinical trial protocols would require resubmission to
the FDA and IRBs for review and approval, which may adversely impact the cost, timing or successful completion of clinical trials.   If we or
our collaborators experience delays completing, or if we or our collaborators terminate, any of our non-clinical studies or clinical trials, or if we
or our collaborators are required to conduct additional non-clinical studies or clinical trials, the development pathway, and ultimately the
commercial prospects, for our product candidates may be harmed and our ability to generate product revenue from resulting products, if any,
will be delayed.

We or our collaborators may never seek or receive regulatory approval to market any of our products or product candidates outside of the
U.S., or receive pricing and reimbursement outside the U.S. at acceptable levels.  

We or our collaborators may not seek, or may seek but never receive, regulatory approval to market our products or product
candidates outside of the U.S. or in any particular country or region. In order to market any product outside of the U.S., we or our collaborators
must establish and comply with the numerous and varying safety, efficacy and other regulatory requirements of other countries. Approval
procedures vary among countries and can involve additional non-clinical studies or clinical trials, additional work related to manufacturing and
analytical testing on controls, and additional administrative review periods. The time required to obtain approvals in other countries might
differ from that required to obtain FDA approval. Marketing approval in one country does not ensure marketing approval in another, but a
failure or delay in obtaining marketing approval in one country may have a negative effect on the regulatory process in other countries. The
marketing approval processes in other countries may implicate all of the risks detailed above regarding FDA approval in the U.S. as well as
other risks. In particular, in many countries outside of the U.S., products must receive pricing and reimbursement approval before the product
can be commercialized. Obtaining this approval may require additional studies and data, and can result in substantial delays in bringing
products to market in such countries and such investment may not be justified from a business standpoint given the market opportunity or level
of required investment. Even if we or our collaborators generate the data and information which we believe may be sufficient to file an
application for regulatory approval of any of our products or product candidates in a region or country outside the U.S., the relevant regulatory
agency may find that we did not meet the requirements for approval, or even if our application is approved, we may have significant post-
approval obligations.

Even if we or our collaborators are able to successfully develop our product candidates and obtain marketing approval in a country
outside the U.S., we or they may not be able to obtain pricing and reimbursement approvals in such country at acceptable levels or at all, and
any pricing and reimbursement approval we or they may obtain may be subject to onerous restrictions such as caps, rebates or other hurdles or
restrictions on reimbursement. Failure to obtain marketing and pricing approval in countries outside the U.S. without onerous restrictions or
limitations related to pricing, or any delay or other setback in obtaining such approval, would impair our ability or that of our collaborators to
market our product candidates successfully or at all in such foreign markets. Any such impairment would reduce the size of our potential
market or revenue potential, which could have a material adverse impact on our business, results of operations and prospects.  

Any setback or delay in obtaining regulatory approval or commencing marketing, if approved, for our product candidates in a country
or region outside the U.S. where we or our collaborators have decided it makes business sense to proceed may have a material adverse effect on
our business and prospects.

We rely, and expect that we will continue to rely, on third parties to conduct any clinical trials for our product candidates. If these third
parties do not successfully carry out their contractual duties, comply with applicable

50

 
 
 
 
standards and meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our products, if approved,
and our business could be substantially harmed.

We do not have the ability to independently conduct clinical trials. We rely on medical institutions, clinical investigators, contract
laboratories and other third parties, such as CROs, to conduct clinical trials of our product candidates. We enter into agreements with third-
party CROs to provide monitors for and to manage data for our ongoing clinical trials. We rely heavily on these parties for execution of clinical
trials for our product candidates and control only certain aspects of their activities. As a result, we have less direct control over the conduct,
timing and completion of these clinical trials and the management of data developed through clinical trials than would be the case if we were
relying entirely upon our own staff. Communicating with outside parties can also be challenging, potentially leading to mistakes as well as
difficulties in coordinating activities. Outside parties may:

•

•

•

•

•

•

have staffing difficulties;

fail to comply with contractual obligations;

fail to comply with current Good Clinical Practices, or GCPs, or experience other regulatory compliance issues;

undergo changes in priorities or become financially distressed;

form relationships with other entities, some of which may be our competitors; or

be impacted by the COVID-19 pandemic in ways that adversely affect our business.

These factors may materially adversely affect the willingness or ability of third parties to conduct our clinical trials, and may subject

us to unexpected cost increases that are beyond our control. Nevertheless, we are responsible for ensuring that each of our clinical trials is
conducted in accordance with the applicable protocol, legal and regulatory requirements, and scientific standards, and our reliance on CROs
does not relieve us of our regulatory responsibilities. We, clinical investigators, and our CROs are required to comply with regulations and
guidelines, including GCPs, for conducting, monitoring, recording and reporting the results of clinical trials to ensure that the data and results
are scientifically credible and accurate, and that the trial patients are adequately informed of the potential risks of participating in clinical trials.
These regulations are enforced by the FDA, the Competent Authorities of the Member States of the European Economic Area, or EEA, and
comparable foreign regulatory authorities for any product candidates in clinical development or where clinical trials are being conducted. If we
or our CROs or contract manufacturers fail to comply with these regulations or if the quality or accuracy of the clinical data obtained is
compromised due to the failure to adhere to our clinical protocols or other regulatory requirements or for other reasons, and we are unable to
rely on clinical data collected, we may be required to repeat clinical trials or extend the duration of, or increase the size of our clinical trials.
This would delay the regulatory approval process, and could also subject us to enforcement action up to and including civil and criminal
penalties. If any of our relationships with third-party CROs terminate or if a CRO needs to be replaced, we may not be able to enter into
arrangements with alternative CROs in a timely manner or at all. Any of these issues could significantly delay or prevent regulatory approval
of our product candidates and require significantly greater expenditures.  In such an event, we believe that our financial results might be
harmed, our costs could increase and our ability to generate revenue from products beyond ZULRESSO could be delayed.

We rely completely on third-party suppliers to manufacture commercial supplies of ZULRESSO and clinical drug supplies for our product
candidates, and we intend to rely on third parties to produce non-clinical, clinical and commercial supplies of our approved products and
product candidates in the future.

We do not currently have, nor do we plan to acquire or develop, the infrastructure or capability internally to manufacture supplies of

ZULRESSO for commercial use, or of any of our other existing or future product candidates, for use in the conduct of our clinical trials and
non-clinical studies or for future commercial use, and we rely completely on third-party suppliers for both active drug substances and finished
drug products.

51

 
 
 
 
 
 
 
 
We rely on our contract manufacturers for commercial supplies of active drug substance, finished drug product and packaged and
labeled product with respect to ZULRESSO. We also rely on our contract manufacturers to manufacture sufficient quantities of zuranolone,
SAGE-324, SAGE-718, SAGE-689, SAGE-904 and our other product candidates for ongoing and planned clinical trials and non-clinical
studies and expect to rely on them to scale our manufacturing processes for future clinical trials, if our development efforts are successful. We
expect our contract manufacturers to comply with cGMPs in the manufacture of our products. The facilities used by our contract manufacturers
to manufacture the active pharmaceutical ingredient and final drug product must typically complete a pre-approval inspection by the FDA and
other comparable foreign regulatory agencies to assess compliance with applicable requirements, including cGMPs, after we submit the
relevant NDA or equivalent foreign regulatory submission to the applicable regulatory agency. If our contract manufacturers cannot
successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or applicable foreign
regulatory agencies, and pass regulatory inspections, they will not be able to secure and/or maintain regulatory approval for their
manufacturing facilities with respect to our products. In addition, we have no direct control over our contract manufacturers’ ability to maintain
adequate quality control, quality assurance and qualified personnel. Furthermore, all of our third-party contract manufacturers are engaged with
other companies to supply and/or manufacture materials or products for such companies, which exposes our third-party contract manufacturers
to regulatory risks for the production of such materials and products. As a result, failure to satisfy the regulatory requirements for the
production of those materials and products may affect the regulatory clearance of our contract manufacturers’ facilities generally. If the FDA or
an applicable foreign regulatory agency determines now or in the future that these facilities for the manufacture of our products and product
candidates are noncompliant, we may need to find alternative manufacturing facilities, which would significantly adversely delay or impact our
commercialization efforts for any approved product and our ability to develop and obtain regulatory approval for our product candidates. Our
reliance on contract manufacturers also exposes us to the possibility that they, or third parties with access to their facilities, will have access to
and may appropriate our trade secrets or other proprietary information. Also, if a natural disaster were to interrupt or halt production of our
drug substance or drug product at one of our third-party contract manufacturers, or cause the loss of batches, we could encounter a supply
shortage or face significant costs to rebuild our supply.

We have long-term supply agreements with our contract manufacturers with respect to ZULRESSO drug substance and drug product.

We have an inventory of ZULRESSO drug product and drug substance in place to help mitigate any potential supply risks, but there is no
guarantee that this inventory will be adequate. We do not yet have long-term supply agreements in place with our contract manufacturers with
respect to drug substance or drug product for any of our product candidates. Each batch of drug substance and drug product for our product
candidates is individually contracted through a purchase order governed by our master service and quality agreements. If our existing contract
manufacturers for our other product candidates are not willing to enter into long-term supply agreements, or are not willing or are unable to
supply drug substance or drug product to us, we could be required to engage new contract manufacturers who would need to scale up the
manufacturing process before we would be able to use the drug product or drug substance they manufacture for clinical trials. In addition, in
such event, any such contract manufacturer would need to complete validation batches, pass an inspection by the FDA and other applicable
foreign regulatory agencies, and be approved by regulatory authorities as our manufacturer before we would be able to use drug product or
drug substance they manufacture for commercial purposes, which could result in significant delays or gaps in product availability. We plan to
continue to rely upon contract manufacturers to manufacture commercial quantities of our products, if approved. If we are unable to maintain
arrangements for third-party manufacturing, or are unable to do so on commercially reasonable terms, or are unable to obtain timely regulatory
approvals in connection with our contract manufacturers, we may not be able to successfully commercialize any approved product or
successfully complete development of our current or future product candidates.

ZULRESSO or any future product, if our ongoing development efforts are successful, may not achieve broad market acceptance or
reimbursement at sufficient levels, which would limit the revenue that we generate from its sales.

The commercial success of ZULRESSO or of any of our current or future product candidates, if successfully developed and approved

by the FDA or other applicable regulatory authorities, will depend upon the awareness and

52

 
 
acceptance among the medical community, including physicians, patients and healthcare payors, and reimbursement at sufficient levels.

The availability of coverage and adequacy of reimbursement is essential for most patients to be able to access and afford treatments.
Patients who are prescribed medications for the treatment of their conditions generally rely on third-party payors to reimburse all or part of the
costs associated with their prescription drugs. Government authorities, including the Centers for Medicare and Medicaid Services, or CMS, an
agency within the Department of Health and Human Services, or HHS, in the U.S., and third-party payors, such as private health insurers and
health maintenance organizations, decide which medications they will pay for and establish reimbursement levels for those medications. Cost
containment is a primary concern in the U.S. healthcare industry and elsewhere. Government authorities and these third-party payors have
attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Payors may adopt restrictions on
coverage such as requiring patients to try other lower cost therapies prior to being prescribed our product, requiring patients to meet severity or
other criteria more restrictive than the approved label for our product, or requiring onerous and time-consuming prior authorization procedures,
or they may limit the amount of reimbursement. These restrictions or limitations might impede appropriate use of our product for the approved
indication.  Restrictions and limitations on reimbursement or delays in obtaining coverage may vary significantly among payors and payor
types. As a result, there is significant uncertainty related to third-party payor coverage and reimbursement of approved drugs. Regulatory
approvals, pricing and reimbursement for drug products vary widely from country to country. Coverage and reimbursement by a third-party
payor may depend upon a number of factors, including the third-party payor’s determination that use of a product is a covered benefit under its
health plan; safe, effective and medically necessary; appropriate for the specific patient; cost-effective; and neither experimental nor
investigational.

The inability of us or our collaborators to promptly obtain and maintain coverage and adequate reimbursement rates from both

government-funded and private payors for ZULRESSO and any other approved products that we develop could have a material adverse effect
on our operating results, our ability to successfully commercialize our products, our ability to raise capital and our overall financial condition.
Even if coverage is provided, we may not be able to establish or maintain pricing sufficient to realize a sufficient return on our investment.

Obtaining coverage and reimbursement approval for a product from a government or other third-party payor can be an expensive and
time-consuming process that could require us to provide supporting scientific, clinical and cost effectiveness data for the use of our products to
the payor. For example, the availability, terms and timing of coverage for ZULRESSO varies from payor to payor, both for commercially
insured patients and from state Medicaid systems, and we have encountered some states that impose significant coverage restrictions or lengthy
delays on reimbursement of ZULRESSO. As a result, certain healthcare settings will not treat Medicaid patients with ZULRESSO even if they
are active treating sites of care for ZULRESSO. The industry competition to be included in third-party payors’ drug formularies, or lists of
medications for which third-party payors provide coverage and reimbursement, often leads to downward pricing pressures on pharmaceutical
products. In addition, third-party payors may refuse to include a particular branded drug in their formularies or otherwise restrict patient access
to a branded drug when a less costly generic equivalent or other alternative is available. 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 U.S. Increasingly, third-party payors are requiring that drug
companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. In addition,
many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as average sales price
and best price. Penalties may apply when such metrics are not submitted accurately and on a timely basis. Before granting reimbursement
approval, payors may require us to demonstrate that our product candidates, in addition to treating the target indications, also provide
incremental health benefits to patients or healthcare costs savings. We cannot be sure that adequate coverage or reimbursement will be
available for any product candidate that we or our collaborators commercialize.

Market acceptance will depend on a number of factors, including, among others:

•

the efficacy and safety of our products as demonstrated in clinical trials;

53

 
 
 
•

•

•

•

•

•

•

•

•

the potential and perceived advantages and limitations of our products over current or future alternative treatment options, including
in the case of ZULRESSO, the impact of limitations arising from the intravenous infusion mode of administration, the length of stay
required for treatment, restrictions on site of care to REMS certified healthcare settings and other requirements of the REMS, the risk
of excessive sedation and loss of consciousness during administration, and the availability of lower cost antidepressants;

the incidence and severity of any side effects of the products;

limitations or warnings contained in the labeling approved for our products by the FDA or other applicable regulatory authorities;

the clinical indications and size of patient populations for which our products are approved;

the convenience, benefit, ease and availability of alternative treatments already approved or expected to be commercially launched in
the near future;

the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies, and our ability to
increase awareness of our approved products through marketing efforts;

the strength and effectiveness of our sales, marketing and distribution strategies and support or that of our collaborators;

publicity concerning our products or competing products and treatments;

pricing and cost effectiveness; or

•

the availability of sufficient third-party coverage or reimbursement, and the willingness of patients to pay out-of-pocket in the
absence of such coverage or reimbursement, including in the case of ZULRESSO for both the product and the cost of the infusion.

Our efforts to change the treatment paradigm for a given disorder or to educate the medical community and third-party payors about

the benefits of any current or future products, to the extent permitted, may require significant resources and may never be successful.   If
ZULRESSO, or any of our product candidates that may be approved in the future, do not achieve an adequate level of acceptance by patients,
physicians, healthcare settings and payors, or reimbursement at reasonable levels, or if the patient population for which any such product is
approved is smaller than we expect, we may not generate sufficient revenue from our products to become or remain profitable or may not do so
on the timelines we expect.

Even after marketing approval of a product, we face significant post-marketing obligations and future development and regulatory
difficulties.

Regulatory authorities may impose significant and potentially costly post-marketing obligations with respect to approval of any

product, including post-marketing studies, additional CMC work and additional pediatric studies. For example, the FDA has imposed post-
marketing commitments with respect to approval of ZULRESSO, and we may encounter issues or delays in the conduct of these post-
marketing commitments or we may generate unexpected results.

In the event we or our collaborators elect, or are required, to proceed with pediatric studies of any of our product candidates in any

indication, regulatory authorities may also require additional non-clinical studies or clinical trials be completed prior to commencement of such
pediatric studies.

As was the case with brexanolone, the FDA may recommend controlled substance scheduling for our current or future product

candidates, if approved.  In such event, the DEA will need to determine the controlled substance schedule

54

 
 
 
 
 
 
 
 
 
 
 
 
 
taking into account the recommendation of the FDA. If products are determined to be controlled substances, the manufacturing, shipping,
storing, selling and using of the products will be subject to an additional regulation. Distribution, prescribing and dispensing of these drugs are
also regulated. Because of their restrictive nature, these laws and regulations could limit commercialization of our product candidates
containing controlled substances. Failure to comply with these laws and regulations could also result in withdrawal of our DEA registrations,
disruption in manufacturing and distribution activities, consent decrees, criminal and civil penalties and state actions, among other
consequences.  The DEA regulates controlled substances as Schedule I, II, III, IV or V substances. Schedule I substances by definition have no
established medicinal use, and may not be marketed or sold in the U.S. A pharmaceutical product may be listed as Schedule II, III, IV or V,
with Schedule II substances considered to present the highest risk of abuse and Schedule V substances the lowest relative risk of abuse among
such substances.  Brexanolone is currently regulated as a Schedule IV controlled substance.  Other Schedule IV controlled substances include
sedative hypnotics such as benzodiazepines.

ZULRESSO is, and any future approved products will also be, subject to ongoing FDA requirements governing the labeling,
packaging, storage and promotion of the product and record-keeping and submission of safety and other post-market information. The FDA has
significant post-marketing authority, including, for example, the authority to require labeling changes based on new safety information and to
require post-marketing studies or clinical trials to evaluate serious safety risks, safety and efficacy in pediatric populations or alternate doses or
dose regimens.

The FDA also has the authority to require, as part of an NDA or post-approval, the submission of a REMS.  For example, the FDA

has required a REMS for ZULRESSO.  Any REMS required by the FDA may lead to increased costs to assure compliance with the REMS and
with additional post-approval regulatory requirements and potential requirements or restrictions on the sale of approved products, all of which
could lead to lower sales volume and revenue.  In addition, if we are unable to comply with the ZULRESSO REMS or any REMS imposed for
a future product, we may face additional restrictions, limitations or substantial penalties, any of which may materially adversely affect our
business and results of operations.

We, our collaborators and the third-party manufacturers of our drug substance and drug products and our respective facilities are

subject to extensive regulations in the manufacture of our products and product candidates, including GMP, and are subject to continual review
and periodic inspections by the FDA and other regulatory authorities for compliance with GMPs and other regulations. If we, our collaborators
or a regulatory agency discover problems with our approved products or product candidates such as poor control of production processes or
other problems with the facility where our products are manufactured or in the manufacturing process, introduction of contaminants, or adverse
events of unanticipated severity or frequency, a regulatory agency may impose restrictions on our products, the manufacturer or us or our
collaborators, including requiring withdrawal of such products from the market or suspension of manufacturing. If we, our collaborators, our
approved products, our product candidates, or the manufacturers for our products or product candidates fail to comply with applicable
regulatory requirements, a regulatory agency may, among other things:

•

•

•

•

•

•

•

issue warning letters or untitled letters;

seek an injunction or impose civil or criminal penalties or monetary fines;

suspend or withdraw marketing approval;

suspend any ongoing clinical trials;

refuse to approve pending applications or supplements to applications submitted by us;

suspend or impose restrictions on operations, including costly new manufacturing requirements; or

seize or detain products, refuse to permit the import or export of products, or require that we initiate a product recall.

55

 
 
 
 
 
 
 
 
 
Competing therapies may exist or could emerge that adversely affect the amount of revenue we are able to generate from the sale of
ZULRESSO or any of our current or future product candidates, if successfully developed and approved.

The biopharmaceuticals industry is highly competitive. There are many public and private companies, universities, governmental

agencies and other research organizations actively engaged in the research and development of products that may be similar to our products or
product candidates or address similar markets. It is probable that the number of companies seeking to develop products and therapies similar to
our products will increase.  Many of our potential competitors, alone or with their strategic partners, have substantially greater financial,
technical and human resources than we do, and significantly greater experience in the discovery and development of product candidates,
obtaining FDA and other regulatory approvals of treatments and the commercialization of those treatments. Mergers and acquisitions in the
biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number of our
competitors. We expect competition in the indications we are pursuing will focus on efficacy, safety, convenience, availability, and price.  Our
commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are perceived to be safer,
more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop. Our
competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which
could result in our competitors establishing a strong market position before we are able to enter the market.

Currently, there are no pharmacological therapies specifically approved for the treatment of PPD other than ZULRESSO.  Current

standard of care for PPD commonly consists of psychotherapy; however, patients with moderate or severe PPD are often prescribed
antidepressant medications such as selective serotonin reuptake inhibitors, or SSRIs, and serotonin and norepinephrine reuptake inhibitors, or
SNRIs.  

Our most advanced development candidate, zuranolone, is in Phase 3 development for MDD and PPD.  Patients with MDD are

typically treated with a variety of antidepressant medications, including SSRIs and SNRIs. If successfully developed and approved, zuranolone
may also face competition from esketamine, which is approved in the treatment of treatment resistant depression. A number of companies are
developing product candidates intended for the treatment of MDD, including NMDA receptor antagonists or partial antagonists such as
dextromethorphan/ bupropion. In November 2020, Axsome Therapeutics, Inc. announced that it expected to file its NDA for its NMDA
receptor antagonist, AXS-05, in January 2021. In addition, if zuranolone is successfully developed and approved for PPD, it could reduce our
commercial opportunity for ZULRESSO.

In the field of neuroactive steroids focused specifically on modulation of GABAA receptors, we also face competition from a number of
companies, including Marinus Pharmaceuticals, Inc., or Marinus, and Praxis Precision Medicines, or Praxis.  Marinus is developing a form of
ganaxolone, a known GABAA positive allosteric modulator neuroactive steroid, that is in Phase 3 trials in patients with status epilepticus and
CDLK5 deficiency disorder. Praxis is developing PRAX-114, a GABAA receptor modulating neuroactive steroid, for MDD and is currently
reported as being in Phase 2/3 development.

SAGE-324, a novel GABAA receptor positive allosteric modulator, is in Phase 2 development in essential tremor. If successfully

developed and approved, SAGE-324 may face competition from a Phase 2b-ready T-type calcium channel modulator in development for
essential tremor by Jazz Pharmaceuticals, Inc.

A number of companies are working to develop products targeted at the NMDA receptor, both antagonists and agonists. Aptinyx Inc. has

multiple Phase 2 NMDA receptor modulators in development for multiple indications, including NYX-458 for the treatment of cognitive
impairment in Parkinson’s disease.

We have existing collaborations, and may seek to establish additional collaborations, related to our development and commercialization of
product candidates.  Our existing and future collaborations, if any, may not lead to the successful development or commercialization of
product candidates. If we determine that future collaborations are important to our business, and we are not able to establish future
collaborations on commercially reasonable terms, we may have to alter our development and commercialization plans or expand our
internal efforts and growth.  

56

 
 
Our drug development programs and the potential commercialization of our product candidates will require substantial additional

cash to fund expenses. For some of our product candidates, we may decide to collaborate with pharmaceutical and biotechnology companies
for the development and potential commercialization of those product candidates in some or all markets.

Our existing and future collaborations, if any, may not lead to the successful development and commercialization of any

products.  Our collaborators face both the same challenges and hurdles that we would face in the development and commercialization of
product candidates if we were engaged in the activities ourselves, as well as additional challenges related to operating under a collaboration.
For example, we have entered into a collaboration agreement with Biogen MA Inc., or BIMA, and Biogen International GmbH, or, collectively
with BIMA, Biogen, to jointly develop and commercialize zuranolone and SAGE-324 in the U.S. and granting Biogen rights to develop and
commercialize those product candidates in the rest of the world other than Japan, Taiwan and South Korea, or the Existing Partner Territory, in
the case of zuranolone.  We have a separate collaboration with Shionogi & Co., Ltd., or Shionogi, under which we granted rights to Shionogi
for the development and commercialization of zuranolone in the Existing Partner Territory.  The efforts under these collaborations may not be
successful and we may never receive any additional milestone payments, profit-share revenue or royalty payments from Biogen or Shionogi. In
addition, under most collaborations, a certain degree of control in decision-making is transferred to or shared with our collaborators in these
efforts which may lead to decisions that hamper our overall development and commercialization activities.  Our collaborators may face
competing priorities or different incentives that divert resources away from our collaboration; may independently develop, or develop with a
competitor, competitive products; or may believe that product candidates being evaluated in the collaboration could be competitive with the
collaborator’s own products. In the case of the collaboration with Biogen, both companies have agreed to certain exclusivity provisions in
specified indications which may limit certain development opportunities outside the collaboration. In addition, if we depend on collaborators
for capabilities and funding for major product development efforts globally or in key territories then our business may be adversely affected if
the collaboration terminates or if our collaborator fails to perform its obligations under the agreement. Disputes may also arise with respect to
the ownership of rights to technology or products developed with collaborators, which could have an adverse effect on our ability to develop
and commercialize any affected product candidate.  

Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a significant number of

recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.
We may not be able to negotiate additional collaborations on a timely basis, on acceptable terms, or at all.  

We may not be successful in our efforts to identify or discover additional product candidates beyond our existing product candidates or to
file investigational new drug, or IND, applications for clinical development of new compounds at the rate we expect, or we may expend our
limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may
be more profitable or for which there is a greater likelihood of success.

The success of our business depends upon our and our collaborators’ ability to successfully develop, gain approval of and
commercialize products based on our current product candidates and on our ability to generate new compounds for development in the future
and to successfully complete the non-clinical work necessary to file INDs to pursue clinical development of such new compounds. Our
research programs may fail to generate new compounds that meet the standards for non-clinical development, and, if even we are successful in
generating such compounds, we may not be able to produce the non-clinical and other data necessary to support IND applications for clinical
development, in each case in the number or at the rate we expect or at all for a number of reasons. For example, we may not be able to identify
a sufficient number of new targets in areas of interest to us. Our research methodology may be unsuccessful in generating a sufficient number
of new compounds appropriate for non-clinical testing in the target areas we identify.  Even if we generate new compounds in areas of interest
to us, we may determine that those compounds are not appropriate for non-clinical development or we may generate data in non-clinical
development that do not support IND filings for clinical development.  We may not have, or devote, sufficient technical, financial, and human
resources to our research efforts at the various stages needed to identify targets, generate compounds, conduct non-clinical studies and

57

 
 
prepare INDs.  Additional potential product candidates may be shown to have harmful side effects or may not have a positive risk/benefit
profile or may have other characteristics that may make the product candidates not appropriate for further development or unlikely to receive
marketing approval.

Because we have limited financial and management resources, we focus on a limited number of clinical and research programs and

product candidates and are currently focused on certain brain health disorders. As a result, we may forego or delay pursuit of opportunities with
other product candidates or for other indications that later prove to have greater commercial potential. Research programs to identify new
product candidates require substantial technical, financial and human resources. We may focus our efforts and resources on potential programs
or product candidates that ultimately prove to be unsuccessful and may not yield any commercially viable drugs. Our resource allocation
decisions may cause us to fail to capitalize on other viable opportunities. If we do not accurately evaluate the commercial potential or target
market for a particular product candidate, we may relinquish valuable rights through future collaboration, licensing or other royalty
arrangements in cases in which it would have been more advantageous for us to retain such sole development and commercialization rights.  If
any of these events occur, it may have a material adverse effect on our business.

If our development efforts related to our current and future product candidates are successful, we may need to develop and expand our
company, and we may encounter difficulties in managing this development and expansion, which could disrupt our operations.

Given the complexity and level of activities and resources that may be necessary to potentially commercialize future products, if our

development efforts are successful, we may in the future need to increase our number of employees and the scope of our operations. For
example, if we are ultimately successful in our development efforts with respect to our product candidates, we will need to recruit and train
additional qualified personnel, and continue to implement and improve our managerial, operational and financial systems.  We may not be able
to effectively manage any expansion of our operations or recruit and train additional qualified personnel. This may result in weaknesses in our
infrastructure and give rise to operational mistakes or delays, loss of business opportunities, loss of employees and reduced productivity among
remaining employees. If our management is unable to effectively manage any potential expansion, our expenses may increase more than
expected, and our ability to successfully develop and gain regulatory approval of our product candidates and generate or increase our revenue,
if such product candidates are approved, could be reduced and we may not be able to implement our business strategy. Our future financial
performance and our ability to commercialize any future products that we successfully develop, and to compete effectively will depend, in part,
on our ability to effectively manage the potential future expansion of our company.

Our future success depends on our ability to attract, retain and motivate qualified personnel.

To accomplish our objectives, we require a strong management team with expertise in research and development, clinical

development and commercialization. Although we have entered into employment agreements with each of our executive officers, each of them
is employed “at will” and may terminate his or her employment with us at any time.  We do not maintain “key person” insurance for any of our
executives or other employees.  Recruiting and retaining qualified personnel is critical to our success. We may not be able to attract and retain
these personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar
personnel. We also experience competition for the hiring of scientific personnel from universities and research institutions. Failure to succeed
in clinical trials or in obtaining regulatory approval may make it more challenging to recruit and retain qualified personnel. If we are unable to
continue to attract and retain high quality personnel, our business, financial condition, results of operations and growth prospects could be
adversely affected.

We face potential product liability exposure, and, if claims are brought against us, we may incur substantial liability.

The sale of ZULRESSO and any future approved products and use of our product candidates in clinical trials will expose us to the

risk of product liability claims. Product liability claims might be brought against us by patients,

58

 
 
healthcare providers or others using, prescribing, selling or otherwise coming into contact with our products and product candidates. For
example, we may be sued if any product or product candidate allegedly causes injury or is found to be otherwise unsuitable during clinical
trials, manufacturing, marketing, sale or commercial use. Any such product liability claims may include allegations of defects in
manufacturing, defects in design, a failure to warn of dangers inherent in the product, including as a result of interactions with alcohol or other
drugs, knowledge of risks, negligence, strict liability and a breach of warranties. Claims could also be asserted under state consumer protection
laws. If we become subject to product liability claims and cannot successfully defend ourselves against them, we could incur substantial
liabilities. Regardless of merit or eventual outcome, product liability claims may result in, among other things:

•

•

•

•

•

•

•

•

•

withdrawal of patients from our clinical trials, or difficulty in enrolling clinical trials;

substantial monetary awards to patients or other claimants;

decreased demand for our approved products;

damage to our reputation and exposure to adverse publicity;

increased FDA warnings on product labels;

litigation costs;

distraction of management’s attention from our primary business;

loss of revenue; and

withdrawal of products from the market or our inability to successfully gain approval of product candidates.

We maintain product liability insurance coverage with a $20.0 million annual aggregate coverage limit. Nevertheless, our insurance

coverage may be insufficient to reimburse us for any expenses or losses we may suffer. Moreover, in the future, we may not be able to maintain
insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses, including if insurance coverage becomes
increasingly expensive. Large judgments have been awarded in class action lawsuits based on drugs that had unanticipated side effects. The
cost of any product liability litigation or other proceedings, even if resolved in our favor, could be substantial, particularly in light of the size of
our business and financial resources. A product liability claim or series of claims brought against us could cause our stock price to decline and,
if we are unsuccessful in defending such a claim or claims and the resulting judgments exceed our insurance coverage, our financial condition,
business and prospects could be materially adversely affected.

If we fail to comply with our reporting and payment obligations under the Medicaid Drug Rebate Program or other governmental pricing
programs, we could be subject to additional reimbursement requirements, penalties, sanctions and fines, which could have a material
adverse effect on our business, financial condition, results of operations and growth prospects.

The Medicaid Drug Rebate Program, which we participate in, and other governmental programs impose obligations to report pricing

figures to the federal government, require us to pay rebates and participate in discount programs.  Other programs impose limits on the price
we are permitted to charge certain entities for ZULRESSO or for any future products for which we receive regulatory approval. Statutory and
regulatory changes or binding guidance regarding these programs and their requirements could negatively affect the coverage and
reimbursement by these programs of ZULRESSO or any future products for which we receive regulatory approval and could negatively impact
our results of operations.  Our failure to comply with these price reporting and rebate payment obligations could negatively impact our
financial results.  The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010,
collectively referred to herein as the ACA, and regulations promulgated thereunder could affect our obligations in ways we cannot anticipate.

59

 
 
 
 
 
 
 
 
 
 
 
Pricing and rebate calculations vary among products and programs. The calculations are complex and are often subject to

interpretation by us, governmental or regulatory agencies and the courts.  If we become obligated to restate or recalculate the amounts we
report under these programs, our costs for complying with the laws and regulations governing the Medicaid Drug Rebate Program and our
price discounts and rebates could be increased.  Additionally, we could be held liable for errors associated with our submission of pricing data
under the Medicaid Drug Rebate Program and other federal or state drug pricing programs, including retroactive rebates and program refunds,
and if we are found to have knowingly submitted false average manufacturer price or best price information to the government, civil monetary
penalties per item of false information.  Certain failures to submit required data could result in a civil monetary penalty for each day the
information is late beyond the due date and be grounds for CMS to terminate our Medicaid drug rebate agreement, pursuant to which we
participate in the Medicaid program. In the event that CMS terminates our rebate agreement, no federal payments would be available under
Medicaid or Medicare Part B for our covered outpatient drugs.

We are subject to other laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages,
reputational harm and diminished profits and future earnings.  

We are subject to a number of healthcare and other statutory and regulatory requirements and enforcement by the federal government

and the states and foreign governments in which we conduct our business.

Our current or future interactions and arrangements with third-party payors, healthcare providers, patients, healthcare settings, and

others who play a role in the recommendation, prescription, reimbursement and administration of ZULRESSO and will play similar role with
respect to any of our future products, if successfully developed and approved, are governed in part by broadly applicable fraud and abuse and
other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market,
sell and distribute ZULRESSO or expect to market, sell and distribute any future approved products. Restrictions under applicable federal and
state healthcare laws and regulations include the following:

•

•

•

•

The federal anti-kickback statute prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving
or providing remuneration, directly or indirectly (including any kickback, bribe or certain rebate), in cash or in kind, to induce or
reward either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment
may be made under federal healthcare programs such as Medicare and Medicaid. This statute has been interpreted to apply to
arrangements between pharmaceutical companies on the one hand, and prescribers, purchasers and formulary managers, among
others, on the other.

The federal False Claims Act imposes criminal and civil penalties, including those from civil whistleblower or qui tam actions,
against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment
that are false or fraudulent or making a false statement to avoid, decrease, or conceal an obligation to pay money to the federal
government, with potential liability including mandatory treble damages and significant per-claim penalties.  Pharmaceutical
companies have been prosecuted under the False Claims Act in connection with their alleged off-label promotion of drugs,
purportedly concealing price concessions in the pricing information submitted to the government for government price reporting
purposes, and allegedly providing free product to customers with the expectation that the customers would bill federal health care
programs for the product, among other activities. In addition, the government may assert that a claim including items or services
resulting from a violation of the federal anti-kickback statute constitutes a false or fraudulent claim for purposes of the False Claims
Act.

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, imposes criminal and civil liability for executing
a scheme to defraud any healthcare benefit program and also imposes obligations, including mandatory contractual terms, with
respect to safeguarding the privacy, security and transmission of individually identifiable health information.

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and its implementing
regulations, imposes privacy, security and breach reporting obligations, including

60

 
 
 
 
 
 
mandatory contractual terms, with respect to safeguarding the privacy and security of individually identifiable health information
upon covered entities subject to the rule.

The federal false statements statute 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, sometimes referred to as the “Sunshine Act”, under the ACA, require manufacturers of drugs,
devices, biologics and medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program
to report to HHS information related to physician payments and other transfers of value made to physicians and teaching hospitals, as
well as ownership and investment interests held by physicians and their immediate family members. 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.

Analogous state laws and regulations, such as state anti-kickback and false claims laws and transparency laws, may apply to sales or
marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors,
including private insurers, and some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s
voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government in addition to
requiring drug manufacturers to report information related to payments to physicians and other healthcare providers or marketing
expenditures and drug pricing.

Various federal and state health information and data protection laws and regulations, and similar types of laws outside the U.S.,
govern the collection, use, disclosure and protection of health-related and other personal information by us and our collaborators.

•

•

•

Ensuring that our future practices and business arrangements comply with applicable healthcare laws and regulations is costly. It is

possible that governmental authorities will conclude that our business practices and arrangements do not comply with current or future statutes,
regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our practices or operations, including
activities conducted by our commercial team or other of our employees, consultants or vendors, were 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 and exclusion from government funded healthcare programs, such as Medicare and Medicaid, any of which could substantially
disrupt our operations and materially adversely affect our business and financial condition. If any of the physicians or other providers or
entities with whom we expect to do business are found not to be in compliance with applicable laws, they may be subject to criminal, civil or
administrative sanctions, including exclusions from government funded healthcare programs.

We and our employees are also subject to other statutes and regulations related to our business, including: regulations imposed by the
FDA and applicable non-U.S. regulators, as previously discussed; anti-bribery and anti-corruption laws and regulations applicable to activities
outside the U.S.; rules on reporting financial and other information or data timely and accurately; and rules related to insider trading.  

Although we have adopted a code of conduct, it is not always possible to identify and deter employee misconduct, and the
precautions we take to detect and prevent this activity may be ineffective in controlling unknown or unmanaged risks or losses or in protecting
us from governmental investigations or other actions or lawsuits stemming from a failure by our employees to comply with these laws or
regulations.

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

61

 
 
 
 
 
 
 
We must comply with numerous federal, state and non-U.S. laws which govern the privacy and security of health and other personal
information.  As described above, HIPAA, as amended by HITECH and its implementing regulations, imposes certain requirements relating to
the privacy, security and transmission of individually identifiable health information. Among other things, HITECH increased the civil and
criminal penalties that may be imposed and gave state attorneys general new authority to file civil actions for damages or injunctions in federal
courts to enforce the federal HIPAA rules and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, when
we conduct clinical trials in the U.S., any personal information that is collected in connection with these trials also is regulated by the Federal
Policy for the Protection of Human Subjects (the Common Rule) which creates obligations for our company when conducting these trials.

In the event we enroll subjects in our ongoing or future clinical trials in the European Union, or EU, or other countries, we may be

subject to additional privacy restrictions, including restrictions relating to the collection, use, storage, transfer, and other processing of personal
data, including personal health data, regarding these individuals. Clinical trial activities in the EEA, for example, are governed by the General
Data Protection Regulation, or GDPR, in relation to the processing of personal data.  The GDPR imposes several requirements on companies
that process personal data, strict rules on the transfer of personal data out of the EEA, including to the U.S. and fines and penalties for failure to
comply with the requirements of the GDPR and the related national data protection laws of the EU Member States. The GDPR also confers a
private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and
obtain compensation for damages resulting from violations of the GDPR in some situations.  The obligations under the GDPR may be onerous
and adversely affect our business, financial condition, results of operations and prospects. Compliance with the GDPR is a rigorous and time-
intensive process that may increase our cost of doing business or require us to change our business practices, and despite those efforts, there is
a risk that we may be subject to fines and penalties, litigation, and reputational harm in connection with any European activities. The issues
related to the transfer of personal data are subject to substantial uncertainty at this time, and there can be no reasonable level of confidence that
any such data transfers will be found to be consistent with EU law if they are challenged.  Further, the United Kingdom’s exiting of the EU,
often referred to as Brexit, has created additional uncertainty with regard to data protection regulation in the United Kingdom and the ability to
transfer data from the EU to the UK and then from the UK to the U.S.  At this time, it is unclear how data transfers to and from the United
Kingdom will be regulated. Similar laws exist in many other countries around the world, and these laws (which are evolving and expanding)
create complicated and potentially inconsistent obligations that may impact our business.

We are also subject to the California Consumer Privacy Act, or CCPA, which creates individual privacy rights for California

consumers (as defined in the law) and places increased privacy and security obligations on entities handling personal data of consumers or
households. While there is currently an exception for protected health information that is subject to HIPAA and clinical trial regulations, as
currently written, the CCPA may impact our business activities. The CCPA also has been amended through a recent referendum in California
that creates additional obligations beginning in 2023.  Additional states are evaluating similar kinds of general privacy legislation that may
impact our business activities in the future.  The uncertainty, ambiguity, complexity and potential inconsistency surrounding the
implementation and interpretation of CCPA and other potential laws in other states exemplify the vulnerability of our business to the evolving
regulatory environment related to the privacy, security and confidentiality of personal data and protected health information.

The FDA and other regulatory and enforcement agencies actively enforce the laws and regulations prohibiting the promotion of off-label
uses. If we are found to have improperly promoted off-label uses, we may become subject to significant liability.

The FDA and other regulatory and enforcement agencies strictly regulate the promotional claims that may be made about prescription

products, and enforce laws and regulations prohibiting the promotion of off-label uses. In particular, a product may not be promoted for uses
that are not approved by the FDA or such other regulatory agencies as reflected in the approved labeling of the product. If we are found to have
promoted off-label uses for any product, we may become subject to significant liability. The federal government has levied large civil and
criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion.
The FDA has also requested that companies enter into consent decrees or permanent injunctions under which specified promotional

62

 
 
conduct is changed or curtailed. Any promotion of the off-label use of ZULRESSO or any of our future approved products by us or any of our
employees could subject us to significant liability, which would materially adversely affect our business and financial condition.

Our future growth may depend, in part, on our ability to penetrate foreign markets, where we would be subject to additional regulatory
burdens, price controls, reimbursement issues and other risks and uncertainties.

Our future profitability may depend, in part, on our ability, ourselves or through our collaborators, to commercialize our products and

product candidates in foreign markets.

The pricing of prescription pharmaceuticals is subject to governmental control outside the U.S. In these countries, pricing

negotiations with governmental authorities can take considerable time after the receipt of regulatory approval for a product. To obtain
reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our
product candidates to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is
set at unsatisfactory levels, our ability to generate revenues and become profitable could be impaired.

In some countries, including Member States of the EU, the pricing of prescription drugs is subject to governmental control.
Additional countries may adopt similar approaches to the pricing of prescription drugs. 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. In the U.S., recent legislative proposals and various Trump administration proposals have advanced some form of
international reference pricing, with the intent of lowering drug prices in the U.S. by benchmarking U.S. drug prices to prices of similar drugs
in other countries which, if passed by Congress and adopted by the Biden administration, might mean that pricing decisions by us or our
collaborators outside the U.S. in the future may limit the prices we are able to charge for our products in the U.S. Publication of discounts by
third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of publication and other
countries. If pricing is set at unsatisfactory levels or if reimbursement of our products is unavailable or limited in scope or amount, our
revenues from sales by us or our collaborators and the potential profitability of our products in those countries would be negatively affected.

Commercializing our products and product candidates in foreign markets would subject us to additional risks and uncertainties,

including:

•

•

•

•

•

•

•

our inability to directly control commercial activities to the extent we are relying on third parties;

the burden of complying with complex and changing foreign regulatory, tax, accounting and legal requirements, including the
interpretation of contractual provisions governed by foreign laws in the event of a contract dispute;

different medical practices and customs in foreign countries affecting acceptance in the marketplace;

import or export licensing requirements;

longer accounts receivable collection times;

reduced protection of intellectual property rights, and the existence of additional potentially relevant third-party intellectual property
rights, in some foreign countries; and

foreign currency exchange rate fluctuations.

Foreign sales of our product candidates could also be adversely affected by the imposition of governmental controls, political and

economic instability, trade restrictions and changes in tariffs. For example, Brexit has already and

63

 
 
 
 
 
 
 
 
 
may continue to adversely affect European and/or worldwide regulatory conditions. Brexit could continue to lead to legal uncertainty and
potentially divergent national laws and regulations in the EU and the United Kingdom, including those related to the pricing of prescription
pharmaceuticals, as the United Kingdom determines which EU laws to replicate or replace, which could impair our ability to transact business
in the EU and the United Kingdom in the future, if we elect to seek to commercialize any of our products there.

Risks Related to Our Intellectual Property Rights

If we are unable to adequately protect our proprietary technology, or obtain and maintain issued patents that are sufficient to protect our
product candidates, others could compete against us more directly, which would have a material adverse impact on our business, results of
operations, financial condition and prospects.

We strive to protect and enhance the proprietary technologies that we believe are important to our business, including seeking patents

intended to cover our products and compositions, their methods of use and any other inventions that are important to the development of our
business. We may also rely on trade secrets to protect aspects of our business that are not amenable to, or that we do not consider appropriate
for, patent protection.

Our success will depend significantly on our ability to obtain and maintain patent and other proprietary protection for commercially

important technology, inventions and know-how related to our business; defend and enforce our patents, should they issue; preserve the
confidentiality of our trade secrets; and operate without infringing the valid and enforceable patents and proprietary rights of third parties. We
also rely on know-how, continuing technological innovation and in-licensing opportunities to develop, strengthen and maintain the proprietary
position of our product candidates.

We cannot provide any assurances that any of our pending patent applications will mature into issued patents. For example, the U.S.
Patent and Trademark Office, or U.S. PTO, has issued a final rejection against one of our patent applications claiming one of our proprietary
GABAA positive allosteric modulator compounds, asserting a lack of novelty and non-obviousness.  We are in the process of appealing this
decision to the Patent Trial and Appeal Board, and may not be successful in overturning the rejection.

We may be unable to obtain issued patents covering our proprietary compounds. We cannot provide any assurances that any of our

issued patents will be enforceable, or include claims with a scope sufficient to protect our product candidates or otherwise provide any
competitive advantage. For example, the issued patent and patent applications that provide coverage for ZULRESSO only cover particular
formulations and particular methods of using such formulations to treat depressive disorders such as PPD and MDD. As a result, such issued
patent and any patent that may issue from such patent applications, would not prevent third-party competitors from creating, making and
marketing alternative formulations of brexanolone that fall outside the scope of the patent claims or from practicing alternative methods.
Moreover, other parties have developed technologies that may be related or competitive to our approach, and may have filed or may file patent
applications and may have received or may receive patents that may overlap or conflict with our patent applications, either by claiming the
same methods or formulations or by claiming subject matter that could dominate our patent position. Such third-party patent positions may
limit or even eliminate our ability to obtain patent protection for certain inventions.

The patent positions of biotechnology and pharmaceutical companies, including our patent position, involve complex legal and

factual questions, and, therefore, the issuance, scope, validity and enforceability of any patent claims that we may obtain cannot be predicted
with certainty. Patents, if issued, may be challenged, deemed unenforceable, invalidated, or circumvented. U.S. patents and patent applications
may also be subject to interference proceedings, ex parte reexamination, or inter partes review proceedings, supplemental examination and
challenges in district court. Patents may be subjected to opposition, post-grant review, or comparable proceedings lodged in various foreign,
both national and regional, patent offices. These proceedings could result in either loss of the patent or denial of the patent application or loss
or reduction in the scope of one or more of the claims of the patent or patent application. In addition, such proceedings may be costly. For
example, our granted European patent covering brexanolone i.v. has been opposed by a third party, and the opposition proceedings are ongoing.
Thus, any patents, should they issue, that we may own or

64

 
 
 
exclusively license may not provide any protection against competitors. Furthermore, an adverse decision in an interference proceeding can
result in a third party receiving the patent right sought by us, which in turn could affect our ability to develop, market or otherwise
commercialize our product candidates. Furthermore, though a patent, if it were to issue, is presumed valid and enforceable, its issuance is not
conclusive as to its validity or its enforceability, and it may not provide us with adequate proprietary protection or competitive advantages
against competitors with similar products.  Even if a patent issues, and is held to be valid and enforceable, competitors may be able to design
around our patents, such as using pre-existing or newly developed technology. Other parties may develop and obtain patent protection for more
effective technologies, designs or methods.  

We also may not be able to prevent the unauthorized disclosure or use of our technical knowledge or trade secrets by consultants,

vendors, former employees and current employees. The laws of some foreign countries do not protect our proprietary rights to the same extent
as the laws of the U.S., and we may encounter significant problems in protecting our proprietary rights in these countries. If these
developments were to occur, they could have a material adverse effect on our sales if any of our product candidates are approved in those
countries.  Our ability to enforce our patent rights depends on our ability to detect infringement. It is difficult to detect infringers who do not
advertise the components that are used in their products. Moreover, it may be difficult or impossible to obtain evidence of infringement in a
competitor’s or potential competitor’s product. Any litigation to enforce or defend our patent rights, even if we were to prevail, could be costly
and time-consuming, and would divert the attention of our management and key personnel from our business operations. We may not prevail in
any lawsuits that we initiate, and the damages or other remedies awarded if we were to prevail may not be commercially meaningful.

In addition, proceedings to enforce or defend our patents, if and when issued, could put our patents at risk of being invalidated, held

unenforceable, or interpreted narrowly. Such proceedings could also provoke third parties to assert claims against us, including that some or all
of the claims in one or more of our patents are invalid or otherwise unenforceable. If any of our patents, if and when issued, covering our
product or product candidates is invalidated or found unenforceable, our financial position and results of operations may be materially and
adversely impacted. In addition, if a court found that valid, enforceable patents held by third parties covered our product candidates, our
financial position and results of operations may also be materially and adversely impacted.

The degree of future protection for our proprietary rights is uncertain, and we cannot ensure that:

•

•

•

•

•

•

•

•

any of our pending patent applications, if issued as a patent, will include claims having a scope sufficient to protect our current
product candidates or any other products or product candidates;

any of our pending patent applications will issue as patents at all;

we will be able to successfully commercialize ZULRESSO or any of our product candidates, if successfully developed and approved,
before our relevant patents expire;

we were the first to make the inventions covered by each of our pending patent applications and any patents that may issue in the
future;

we were the first to file patent applications for these inventions;

others will not develop similar or alternative technologies that do not infringe any patents that may be issued to us;

others will not use pre-existing technology to effectively compete against us;

any of our patents, if issued or as issued, will provide us with a competitive advantage and be found ultimately to be valid and
enforceable;

65

 
 
 
 
 
 
 
 
 
 
•

•

•

any patents issued to us will provide a basis for an exclusive market for our commercially viable products, will provide us with any
competitive advantages or will not be challenged by third parties;

we will develop additional proprietary technologies or product candidates that are separately patentable; or

that our commercial activities or products will not infringe upon the patents or proprietary rights of others.

We may rely upon unpatented trade secrets and depend on unpatented know-how and continuing technological innovation to develop

and maintain our competitive position, which we seek to protect, in part, by confidentiality agreements with our employees and our CROs,
collaborators and consultants. It is possible that technology relevant to our business will be independently developed by a person that is not a
party to such an agreement. Furthermore, if the employees and consultants who are parties to these agreements breach or violate the terms of
these agreements, we may not have adequate remedies for any such breach or violation, and we could lose our trade secrets through such
breaches or violations. Further, our trade secrets could otherwise become known or be independently discovered by our competitors.

We may infringe the intellectual property rights of others, which may prevent or delay our product development efforts and stop us from
commercializing or increase the costs of commercializing ZULRESSO and our other product candidates, if approved.

Our success will depend in part on our ability to operate without infringing the intellectual property and proprietary rights of third

parties. We cannot assure you that our business, products and methods do not or will not infringe the patents or other intellectual property
rights of third parties.  The pharmaceutical industry is characterized by extensive litigation regarding patents and other intellectual property
rights. Other parties may allege that our products or product candidates or the use of our technologies infringes patent claims or other
intellectual property rights held by them or that we are employing their proprietary technology without authorization. As we continue to
develop our current product candidates and commercialize ZULRESSO and any future products, competitors may claim that our technology
infringes their intellectual property rights as part of business strategies designed to impede our successful commercialization. There may be
third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the
use or manufacture of our product candidates. Because patent applications can take many years to issue, third parties may have currently
pending patent applications which may later result in issued patents that our product or product candidates may infringe, or which such third
parties claim are infringed by our technologies. The outcome of intellectual property litigation is subject to uncertainties that cannot be
adequately quantified in advance. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always
uniform. If we are sued for patent infringement, we would need to demonstrate that our product candidates, products or methods either do not
infringe the patent claims of the relevant patent or that the patent claims are invalid or unenforceable, and we may not be able to do this. Even
if we are successful in these proceedings, we may incur substantial costs and the time and attention of our management and scientific personnel
could be diverted in pursuing these proceedings, which could have a material adverse effect on us. In addition, we may not have sufficient
resources to bring these actions to a successful conclusion.

Patent and other types of intellectual property litigation can involve complex factual and legal questions, and their outcome is

uncertain. Patent litigation is costly and time-consuming. Any claim relating to intellectual property infringement that is successfully asserted
against us may require us to pay substantial damages, including treble damages and attorney’s fees if we are found to be willfully infringing
another party’s patents, for past use of the asserted intellectual property and royalties and other consideration going forward if we are forced to
take a license. In addition, if any such claim were successfully asserted against us and we could not obtain such a license, we may be forced to
stop or delay developing, manufacturing, selling or otherwise commercializing our product or product candidates. In the case of trademark
claims, if we are found to be infringing, we may be required to redesign, or rename, some or all of our product candidates to avoid infringing
the intellectual property rights of third parties, which may not be possible and, even if possible, could be costly and time-consuming. Even if
we are successful in these proceedings, we may incur substantial costs and divert management time and attention in pursuing these
proceedings, which could have a material adverse effect on us.

66

 
 
 
 
 
Any of these risks coming to fruition could have a material adverse effect on our business, results of operations, financial condition

and prospects.

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property.

We enter into confidentiality and intellectual property assignment agreements with our employees, consultants, CROs, outside
scientific collaborators, and other advisors. These agreements generally provide that inventions conceived by the party in the course of
rendering services to us will be our exclusive property. However, these agreements may not be honored and may not effectively assign
intellectual property rights to us. For example, even if we have a consulting agreement in place with an academic advisor pursuant to which
such academic advisor is required to assign to us any inventions developed in connection with providing services to us, such academic advisor
may not have the right to assign such inventions to us, as it may conflict with his or her obligations to assign all such intellectual property to his
or her employing institution or another party.

Most of our employees have also been previously employed at other biotechnology or pharmaceutical companies, including our

competitors or potential competitors. We also engage advisors and consultants who are concurrently employed at universities or who perform
services for other entities. We may be subject to claims that an employee, advisor or consultant performed work for us that conflicts with that
person’s obligations to a third party, such as an employer, and thus, that the third party has an ownership interest in the intellectual property
arising out of work performed for us.

Litigation may be necessary to defend against these and other claims challenging inventorship or ownership. If we fail in defending

any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or
right to use, valuable intellectual property. Such an outcome could have a material adverse effect on our business. Even if we are successful in
defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees which could
have a materially adverse effect on our business.

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

The U.S. PTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee

payment and other formalities and 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.

We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time-consuming
and unsuccessful.

Even if the patent applications we own or license are issued, competitors may infringe these patents. To counter infringement or

unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. In addition, in an infringement
proceeding, a court may decide that a patent of ours or our licensors is not valid, is unenforceable and/or is not infringed, or may refuse to stop
the other party from using the technology at issue on the grounds that our patents should be interpreted narrowly and do not cover the
technology in question. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being
invalidated or interpreted narrowly and could put our patent applications at risk of not issuing.

Interference proceedings provoked by third parties or brought by us may be necessary to determine the priority of inventions with

respect to our patents or patent applications or those of our licensors. An unfavorable outcome could require us to cease using the related
technology or to attempt to license rights to it from the prevailing party. Our business

67

 
 
could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Our defense of litigation or interference
proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees. We may not be
able to prevent, alone or with our licensors, misappropriation of our intellectual property rights, particularly in countries where the laws may
not protect those rights as fully as in the U.S.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk

that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public
announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive
these results to be negative, it could have a material adverse effect on the price of our common stock.

Issued patents covering our product or any of our product candidates could be found invalid or unenforceable if challenged in court.

If we or one of our collaborators or licensors initiated legal proceedings against a third party to enforce a patent, if and when issued,

covering our product or any of our product candidates, the defendant could counterclaim that the patent covering our product or any of our
product candidates is invalid and/or unenforceable. In patent litigation in the U.S., defendant counterclaims alleging invalidity and/or
unenforceability are commonplace. Grounds for a validity challenge include alleged failures to meet any of several statutory requirements,
including lack of novelty, obviousness or non-enablement. Grounds for unenforceability assertions include allegations that someone connected
with prosecution of the patent withheld relevant information from the U.S. PTO, or made a misleading statement, during prosecution. Third
parties may also raise similar claims before administrative bodies in the U.S. or abroad, even outside the context of litigation. Such
mechanisms include re-examination, post-grant review, ex parte reexamination, or inter partes review and equivalent proceedings in foreign
jurisdictions, e.g., opposition proceedings. Such proceedings could result in revocation or amendment of our patents in such a way that they no
longer cover our product candidates or competitive products. For example, our granted European patent covering brexanolone i.v. has been
opposed by a third party, and the opposition proceedings are ongoing. The outcome following legal assertions of invalidity and
unenforceability is unpredictable. With respect to validity, for example, we cannot be certain that there is no invalidating prior art, of which we
and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or
unenforceability, we would lose at least part, and perhaps all, of the patent protection on the applicable product or product candidates. Such a
loss of patent protection would have a material adverse impact on our business.

We will not seek to protect our intellectual property rights in all jurisdictions throughout the world and we may not be able to adequately
enforce our intellectual property rights even in the jurisdictions where we seek protection.

Filing patent applications and prosecuting and defending patents on product candidates in all countries and jurisdictions throughout

the world would be prohibitively expensive, and our intellectual property rights in some countries outside the U.S. could be less extensive than
those in the U.S., assuming that rights are obtained in the U.S. In addition, the laws of some foreign countries do not protect intellectual
property rights to the same extent as federal and state laws in the U.S. Consequently, we may not be able to prevent third parties from
practicing our inventions in all countries outside the U.S., or from selling or importing products made using our inventions in and into the U.S.
or other jurisdictions. The statutory deadlines for pursuing patent protection in individual foreign jurisdictions are based on the priority date of
each of our patent applications.

Competitors may use our technologies in jurisdictions where we do not pursue patent protection. They may pursue and obtain their

own patent protection to develop their own products. Further, they may export otherwise infringing products to territories where we have patent
protection, but enforcement is not as strong as that in the U.S. 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. Even if we pursue and obtain issued patents in
particular jurisdictions, our patent claims or other intellectual property rights may not be effective or sufficient to prevent third parties from so
competing.

68

 
 
The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the U.S. Many

companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The
legal systems of some countries, particularly developing countries, do not favor the enforcement of patents and other intellectual property
protection, especially those relating to biotechnology and pharmaceuticals. For example, a 2020 report from the Office of the U.S. Trade
Representative identified a number of countries, including India and China, where challenges to the procurement and enforcement of patent
rights have been reported. Several countries, including India and China, have been listed in the report every year since 1989. This could make it
difficult for us to stop the infringement of our patents, if obtained, or the misappropriation of our other intellectual property rights in such
jurisdictions. Many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. In
addition, many countries limit the enforceability of patents against third parties, including government agencies or government contractors. In
these countries, patents may provide limited or no benefit. Patent protection must ultimately be sought on a country-by-country basis, which is
an expensive and time-consuming process with uncertain outcomes. Accordingly, we may choose not to seek patent protection in certain
countries, and we will not have the benefit of patent protection in such countries.

Furthermore, proceedings to enforce our patent rights in foreign jurisdictions could, among other things, result in substantial costs and

divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly,
could put 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. Accordingly, our efforts to
enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual
property that we develop or license.

For ZULRESSO and certain of our product candidates, we are dependent on licensed intellectual property. If we were to lose our rights to
licensed intellectual property, we may not be able to continue developing or commercializing certain of our products or product candidates,
if approved. If we breach any of the agreements under which we license the use, development and commercialization rights to our product
candidates or technology from third parties or, in certain cases, we fail to meet certain development deadlines, we could lose license rights
that are important to our business.

We are a party to a number of license agreements under which we are granted rights to intellectual property that are important to our

business and we expect that we may need to enter into additional license agreements in the future. Our existing license agreements impose, and
we expect that future license agreements will impose on us, various development, regulatory and/or commercial diligence obligations, payment
of milestones and/or royalties and other obligations. If we fail to comply with our obligations under these agreements, or we are subject to a
bankruptcy, the licensor may have the right to terminate the license, in which event we would not be able to market products covered by the
license. Our business could suffer, for example, if any current or future licenses terminate, if the licensors fail to abide by the terms of the
license, if the licensed patents or other rights are found to be invalid or unenforceable, or if we are unable to enter into necessary licenses on
acceptable terms.

As we have done previously, we may need to obtain licenses from third parties to advance our research or allow commercialization of

our product candidates, and we cannot provide any assurances that third-party patents do not exist that might be enforced against our current
product candidates or future products in the absence of such a license. We may fail to obtain any of these licenses on commercially reasonable
terms, if at all. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies
licensed to us. In that event, we may be required to expend significant time and resources to develop or license replacement technology. If we
are unable to do so, we may be unable to develop or commercialize the affected product candidates, which could materially harm our business
and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales, or, with respect to our sales,
an obligation on our part to pay royalties and/or other forms of compensation.

69

 
 
Licensing of intellectual property is of critical importance to our business and involves complex legal, business and scientific issues.

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

•

•

•

•

•

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

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

our right to sublicense patent and other rights to third parties under licenses or collaborative development relationships;

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

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

If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing

arrangements on acceptable terms, we may be unable to successfully commercialize our product or to successfully develop and commercialize
the affected product candidates.

We have entered into several licenses to support our various programs. We may enter into additional licenses to third-party
intellectual property that are necessary or useful to our business. Our current licenses and any future licenses that we may enter into impose
various royalty payment, milestone, and other obligations on us. For example, the licensor may retain control over patent prosecution and
maintenance under a license agreement, in which case, we may not be able to adequately influence patent prosecution or prevent inadvertent
lapses of coverage due to failure to pay maintenance fees. If we fail to comply with any of our obligations under a current or future license
agreement, the licensor may allege that we have breached our license agreement, and may accordingly seek to terminate our license. In
addition, future licensors may decide to terminate their licenses with us at will. Termination of any of our current or future licenses could result
in our loss of the right to use the licensed intellectual property, which could materially adversely affect our ability to develop a product
candidate or commercialize a product, as well as harm our competitive business position and our business prospects.

In addition, if our licensors fail to abide by the terms of the license, if the licensors fail to prevent infringement by third parties, if the

licensed patents or other rights are found to be invalid or unenforceable, or if we are unable to enter into necessary licenses on acceptable
terms, our business could materially suffer.

Some intellectual property which we have licensed may have been discovered through government funded programs and thus may be
subject to federal regulations such as “march-in” rights, certain reporting requirements, and a preference for U.S. industry. Compliance
with such regulations may limit our exclusive rights, subject us to expenditure of resources with respect to reporting requirements, and
limit our ability to contract with non-U.S. manufacturers.

Some of the intellectual property rights we have licensed may have been generated through the use of U.S. government funding and

may therefore be subject to certain federal regulations. For example, some of the intellectual property rights licensed to us under the license
agreement with The Regents of the University of California may have been generated using U.S. government funds. As a result, the U.S.
government may have certain rights to intellectual property embodied in our current product or current or future product candidates pursuant to
the Bayh-Dole Act of 1980, or Bayh-Dole Act. These U.S. government rights in certain inventions developed under a government-funded
program include a non-exclusive, non-transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition,
the U.S. government has the right to require us to grant exclusive, partially exclusive, or non-exclusive licenses to any of these inventions to a
third party if the government determines that: (i) adequate steps have not been taken to

70

 
 
 
 
 
 
 
commercialize the invention; (ii) government action is necessary to meet public health or safety needs; or (iii) government action is necessary
to meet requirements for public use under federal regulations (also referred to as “march-in rights”). The U.S. government also has the right to
take title to these inventions if we fail, or the applicable licensor fails, to disclose the invention to the government and fail to file an application
to register the intellectual property within specified time limits. In addition, the U.S. government may acquire title to these inventions in any
country in which a patent application is not filed within specified time limits. Intellectual property generated under a government funded
program is also subject to certain reporting requirements, compliance with which may require us, or the applicable licensor, to expend
substantial resources. In addition, the U.S. government requires that any products embodying the subject invention or produced through the use
of the subject invention be manufactured substantially in the U.S. The manufacturing preference requirement can be waived if the owner of the
intellectual property can show that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees
that would be likely to manufacture substantially in the U.S. or that under the circumstances domestic manufacture is not commercially
feasible. This preference for U.S. manufacturers may limit our ability to contract with non-U.S. product manufacturers for products covered by
such intellectual property.

If we enter into future arrangements involving government funding, and we discover compounds or product candidates as a result of

such funding, intellectual property rights to such discoveries may be subject to the applicable provisions of the Bayh-Dole Act.

If we do not obtain new chemical entity or other types of marketing and data exclusivity for our product candidates and if we do not obtain
additional protection under the Hatch-Waxman Amendments and similar foreign legislation by extending the patent terms of our product
candidates, our business may be materially harmed.

Marketing exclusivity provisions under the Federal Food, Drug, and Cosmetic Act, or FDCA, can delay the submission or the
approval of certain marketing applications by other companies for a product with the same active moiety as a product we may in the future sell.
The FDCA provides a five-year period of non-patent marketing exclusivity within the U.S. to the first applicant to obtain approval of an NDA
for a new chemical entity, or NCE. During the exclusivity period, the FDA may not accept for review an abbreviated new drug application, or
ANDA, or a 505(b)(2) NDA submitted by another company for another drug based on the same active moiety, regardless of whether the drug is
intended for the same indication as the original innovator drug or for another indication, where the applicant does not own or have a legal right
of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of
patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder. The FDCA also provides three
years of marketing exclusivity for a full NDA, or supplement to an existing NDA, if new clinical investigations, other than bioavailability
studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for
example new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the modification for which the drug
received approval on the basis of the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing
the active agent for the original indication or condition of use. We have obtained NCE exclusivity for brexanolone and plan to seek NCE
exclusivity for our current and future product candidates.  There is also no guarantee that our product candidates will qualify for marketing or
data exclusivity under these provisions or that such exclusivity for any of our products will alone be sufficient to for our business.  The
applicable five-year and three-year exclusivity periods of NCE or data exclusivity under the FDCA will not delay the submission or approval
of a full NDA.

Depending upon the timing, duration and specifics of FDA marketing approval of our product candidates, one or more of the U.S.

patents we own or license may be eligible for limited patent term restoration in the future under the Drug Price Competition and Patent Term
Restoration Act of 1984, referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of
up to five years as compensation for patent term lost during product development and the FDA regulatory review process. Even if, at the
relevant time, we have a valid issued patent covering our product, we may not be granted an extension if we were to fail to satisfy applicable
requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to
obtain patent term extension or restoration or the term of any such extension is less than we request, and we do not have

71

 
 
 
any other exclusivity, our competitors may obtain approval of competing products following our patent expiration and our business, financial
condition or results of operations could be adversely affected.

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

Our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biotechnology

industry involves both technological and legal complexity, and is therefore costly, time-consuming and inherently uncertain. In addition, the
U.S. has recently enacted wide-ranging patent reform legislation: the Leahy-Smith America Invents Act, referred to as the America Invents
Act. The America Invents Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent
applications are prosecuted and may also affect patent litigation. It is not yet clear what, if any, impact the America Invents Act will have on
the operation of our business. However, the America Invents Act and its implementation could increase the uncertainties and costs surrounding
the prosecution of our patent applications and the enforcement or defense of any patents that may issue from our patent applications, all of
which could have a material adverse effect on our business and financial condition.

In addition, U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and
weakened the rights of patent owners in certain situations.  For example, in March 2012, in Mayo Collaborative Services, DBA Mayo Medical
Laboratories, et al. v. Prometheus Laboratories, Inc., the U.S. Supreme Court held that several claims drawn to measuring drug metabolite
levels from patient samples and correlating them to drug doses were not patentable subject matter. The decision appears to impact diagnostics
patents that merely apply a law of nature via a series of routine steps and it has created uncertainty around the ability to obtain patent protection
for certain inventions. Additionally, in June 2013, in Association for Molecular Pathology v. Myriad Genetics, Inc., the U.S. Supreme Court
held that claims to isolated genomic DNA are not patentable, but claims to complementary DNA molecules are patent eligible because they are
not a natural product. In June 2014, in Alice Corporation Pty. Ltd. v. CLS Bank International, et al., a case involving patent claims directed to a
method for mitigating settlement risk, the U.S. Supreme Court held that the patent eligibility of claims directed to abstract ideas, products of
nature, and laws of nature should be determined using the same framework set forth in Prometheus. The U.S. PTO has issued a set of
guidelines setting forth procedures for determining subject matter eligibility of claims directed to abstract ideas, products of nature, and laws of
nature in line with the Prometheus, Myriad, and Alice decisions. The guidance does not limit the application of Myriad to DNA but, rather,
applies the decision to other natural products. The full impact of these decisions on our business is not yet known.

In addition to increasing uncertainty with regard to our ability to obtain future patents, this combination of events has created
uncertainty with respect to the value of patents, once obtained. Depending on these and other decisions by the U.S. Congress, the federal courts
and the U.S. PTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new
patents or to enforce any patents that may issue in the future.

Proposed legislation in Congress, if passed into law, could limit the patent exclusivity on our products or facilitate earlier entry of generic
competition.

Members of Congress have proposed numerous legislative initiatives aimed at limiting the patent exclusivity on drug products or

facilitating earlier entry of generic versions of approved drugs.  Examples of bills that have been proposed include a bill that, if passed, would
create a presumption of invalidity for patents beyond the first patent covering a drug product thus shifting the burden to the innovator to prove
that these subsequent patents are separately patentable inventions, distinct from the first patent; a bill that, if passed, would empower the
Federal Trade Commission to investigate whether large patent portfolios covering a drug product constitute an anti-competitive practice and to
file antitrust lawsuits in such instances; and a bill that, if passed, would limit the availability of a 30-month stay on approval by the FDA of a
generic version of a drug to only those instances where the ANDA litigation involves a composition of

72

 
 
matter patent claiming the drug substance.  Such legislation, if passed into law, could adversely affect ZULRESSO or any future products or
result in earlier entry into the market of generic versions of our drugs.

Risks Related to our Industry

Healthcare regulations aimed at reducing healthcare costs may have a material adverse effect on our business or results of operation.

There have been, and likely will continue to be, legislation and legislative and regulatory proposals in the U.S., both at the federal and

state level, and in many foreign jurisdictions aimed at reducing healthcare costs.  The implementation of unreasonable cost containment
measures, drug pricing control or other reforms that do not recognize the clinical value of innovative medicines could have an adverse effect on
our revenue from ZULRESSO or from the sales of any other products that are successfully developed and approved, and may limit our ability
to achieve profitability.  

For example, in March 2010, the ACA was passed, which substantially changed the way healthcare is financed by both governmental

and private insurers, and significantly impacted the U.S. pharmaceutical industry. The ACA, among other things, subjects biological products
to potential competition by lower-cost biosimilars, provided 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, increased the minimum Medicaid
rebates owed by manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid
managed care organizations, established annual fees and taxes on manufacturers of certain branded prescription drugs, and created a new
Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% (pursuant to the Bipartisan Budget Act of
2018, effective as of 2019) point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage
gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

There have been a number of significant changes to the ACA and its implementation, including as a result of lawsuits, provisions of

other legislation such as The Tax Cuts and Jobs Act of 2017, and executive orders, including many issued by former President Trump. The
ACA remains in effect, but it remains unclear how such litigation and other efforts to repeal and replace the ACA will impact the ACA and our
business.  Litigation and legislation with respect to the ACA are likely to continue, with unpredictable and uncertain results.  It is uncertain
whether the several executive orders related to the ACA and drug pricing issued by President Trump will be repealed or changed by President
Biden.

There has been increasing legislative and enforcement interest in the U.S. with respect to 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 the federal level, the Trump administration’s
proposed budget for fiscal year 2020 contained further drug price control measures and released a “Blueprint” to lower drug prices and reduce
out of pocket costs of drugs that contains additional proposals to increase manufacturer competition, increase the negotiating power of certain
federal healthcare programs, incentivize manufacturers to lower the list price of their products and reduce the out-of-pocket costs of drug
products paid by consumers. There have been multiple Congressional efforts to address specialty drug pricing.  It is unclear whether any such
legislation will be signed into law, and if enacted, what effect it could have on our business.  It is also unclear how the Biden administration
will approach the issue of drug prices. At the state level, legislatures have increasingly passed legislation and implemented regulations
designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions
on certain product access and marketing cost disclosure and price transparency measures, and, in some cases, designed to encourage
importation from other countries and bulk purchasing.

There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels directed at
containing or lowering the cost of healthcare or limiting exclusivity periods for pharmaceutical products.   We cannot predict the initiatives that
may be adopted in the future. The continuing efforts of the government,

73

 
 
insurance companies, managed care organizations and other payors of healthcare services to contain or reduce costs of healthcare and/or
impose price controls may adversely affect:

•

•

•

•

•

the demand for ZULRESSO and for any of our product candidates, if approved;

our ability to receive or set a price that we believe is fair for our products;

our ability to generate revenue and achieve or maintain profitability;

the amount of taxes that we are required to pay; and

the availability of capital.

We expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in additional

reductions in Medicare and other healthcare funding, more rigorous coverage criteria, lower reimbursement, and new payment methodologies.
This could lower the price that we receive for any approved product. Any denial in coverage or reduction in reimbursement from Medicare or
other government-funded programs may result in a similar denial or reduction in payments from private payors, which may prevent us from
being able to generate sufficient revenue from sales of ZULRESSO, successfully commercialize any future products approved in the future,
and achieve profitability.

Our internal computer systems, or those of our collaborators, our third-party CROs or our other contractors or consultants, may fail or
suffer security breaches, which could result in a material disruption of our development programs.

Despite the implementation of security measures, our internal computer systems and those of our collaborators, our third-party CROs

and our other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism,
war and telecommunication and electrical failures.  If such an event were to occur and cause interruptions in our operations, it could result in a
material disruption of our programs or cause us to have liability for disclosure of personal information of our customers. For example, the loss
of clinical trial data for our product candidates could result in delays in our regulatory submission and approval efforts and significantly
increase our costs to recover or reproduce the data, if possible. To the extent that any disruption, disaster or security breach results in a loss of
or damage to our data or applications or other data or applications relating to our technology or product candidates, or inappropriate disclosure
of confidential or proprietary information, we could incur liabilities and the further development of our product candidates could be delayed or
prevented.

We could be required to expend significant amounts of money and other resources to respond to these threats or breaches and to
repair or replace information systems or networks. We also could suffer financial loss or the loss of valuable confidential information. In
addition, we could be subject to regulatory actions and/or claims made by individuals and groups in private litigation involving privacy issues
related to data collection and use practices and other data privacy laws and regulations, including claims for misuse or inappropriate disclosure
of data, as well as unfair or deceptive practices. Although we develop and maintain systems and controls designed to prevent these events from
occurring and we have a process to identify and mitigate threats, the development and maintenance of these systems, controls and processes are
costly and require ongoing monitoring and updating as technologies change and efforts to overcome security measures become increasingly
sophisticated. Moreover, despite our efforts, the possibility of these events occurring cannot be eliminated entirely and there can be no
assurance that any measures we take will prevent cyber-attacks or security breaches that could adversely affect our business.

Risks Related to Our Financial Position and Need for Capital

We are a biopharmaceutical company with a limited operating history, and have not generated significant revenue to date. We have
incurred significant operating losses since our inception, and anticipate that we will incur continued losses for the foreseeable future.

We are a biopharmaceutical company with a limited operating history on which investors can base an investment decision.
Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. We were incorporated in
April 2010.  We have only one approved product, and only began generating revenue from product sales in the second quarter of 2019.

We have funded our operations to date primarily through proceeds from sales of common stock, including the sale of stock to BIMA;

redeemable convertible preferred stock prior to our initial public offering and, to a lesser extent, the issuance of convertible notes. From our
inception through December 31, 2020, we had received aggregate net proceeds of $2.8 billion from such transactions. We also received $1.0
billion in upfront payments under our collaborations with Biogen and Shionogi. As of December 31, 2020, our cash, cash equivalents and
marketable securities were $2.1 billion. We have incurred net losses in each year since our inception, except for net income of $606.1 million
for the year ended December 31, 2020, because of revenue recognized under a license and collaboration agreement with Biogen. Our net loss
was $680.2 million for the year ended December 31, 2019, and our accumulated deficit was $1.0 billion as of December 31, 2020.

Substantially all of our operating losses have resulted from costs incurred in connection with our research and development programs
and from selling, general and administrative costs associated with our operations. We expect to incur increasing levels of operating losses over
the next several years and for the foreseeable future. Our prior losses, combined with expected future losses, have had, and will continue to
have, an adverse effect on our stockholders’ equity and working capital. We expect our research and development expenses to significantly
increase in connection with clinical trials of our product candidates and efforts to seek regulatory approval for any product candidates that
successfully complete clinical development. We also incur significant selling, general and administrative costs in support of ongoing
commercialization efforts with respect to ZULRESSO. In addition, if we obtain marketing approval for our current or future product candidates
beyond ZULRESSO, we will incur significant sales, marketing and outsourced-manufacturing expenses. We incur significant legal and
accounting costs associated with operating as a public company.  We expect to continue to incur additional significant and increasing operating
losses for the foreseeable future. Because of the numerous risks and uncertainties associated with developing pharmaceutical products, we are
unable to predict the extent of any future losses or when we will become profitable, if at all. Even if we do become profitable, we may not be
able to sustain or increase our profitability on a quarterly or annual basis.

Our ability to become profitable depends upon our ability to generate product revenue. We began to generate revenue from product
sales in the second quarter of 2019 in conjunction with launch of our first product, ZULRESSO, which commenced in June 2019.  We expect
that our revenue opportunity for ZULRESSO will continue to be limited. Our ability to generate significant product revenue from any future
approved product depends on a number of factors, including, but not limited to:

•

•

our ability to initiate and successfully complete all efficacy and safety clinical trials and non-clinical studies required to file for, and
obtain, U.S. and foreign marketing approval for our product candidates; and our ability to file for and receive marketing approval to
commercialize our product candidates, if successfully developed; and

with respect to an approved product, our ability, alone or with collaborators, to commercialize the product by developing and
effectively deploying a sales force, and to achieve market acceptance and satisfactory reimbursement of such product in the medical
community, with patients and with third-party payors.

If we are unable to generate significant product revenue, we will not become profitable, and may be unable to continue operations

without continued funding.  

75

 
 
 
 
We expect we will need to raise additional funding at some point in the future, which may not be available on acceptable terms, or at all.
Failure to obtain this necessary capital when needed may force us to delay, limit or terminate our product development efforts or other
operations. Even if we believe we have sufficient funds for our current or future operating plans, we may seek additional capital if market
conditions are favorable or in light of other strategic considerations.  To the extent that we raise additional capital through the sale of
common stock or securities convertible or exchangeable into common stock, the ownership interest of our stockholders in our company will
be diluted.

We are currently commercializing ZULRESSO and advancing our product candidates through non-clinical and clinical development.

Commercializing a product and developing additional small molecule products are expensive. We expect our research and development
expenses to increase substantially as we continue to advance our product candidates in clinical trials, continue our discovery efforts and seek
regulatory approval of our product candidates, if we generate positive data in our other clinical programs.  We also continue to incur significant
expenses in connection with the commercialization of ZULRESSO and would expect commercialization expenses to increase significantly to
commercialize other products, if successfully developed and approved. We expect we will require additional capital in the future to fund
operating needs. We may need to raise additional funds sooner if we choose to pursue additional indications and/or geographies for our product
candidates, conduct additional clinical trials for indications we are already pursuing beyond the anticipated trials, identify new potential
opportunities or otherwise expand our activities more rapidly than we presently anticipate.

As of December 31, 2020, our cash, cash equivalents and marketable securities were $2.1 billion. Based on our current operating

plans, we expect that our existing cash, cash equivalents and marketable securities will be sufficient to fund our anticipated level of operations
for at least the next 12 months from the filing date of this Annual Report. Our current operating plan does not contemplate other development
activities we may pursue or that all of the currently planned activities will proceed at the same pace, or that all of the activities will be fully
initiated or completed during that time. We may use available capital resources sooner than we expect under our current operating plan. In
addition, our operating plan may change. We may need or choose to seek additional funds sooner than planned, through equity or debt
financings, government or other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and
licensing arrangements or a combination of these approaches. In any event, we anticipate we will require additional capital to expand future
development efforts for, obtain regulatory approval for, and to commercialize our product candidates.  If the pandemic and related economic
conditions continue for an extended period, or if our business prospects are impaired or the capital markets disrupted for any other reason,
additional capital may not be available to us on acceptable terms, or at all. Failure to obtain capital if and when needed may force us to delay,
limit or terminate our product development efforts or other operations. Even if we believe we have sufficient funds for our current or future
operating plans, we may seek additional capital if market conditions are favorable or in light of other strategic considerations.  

We cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. In the event

we receive negative data from our key clinical programs or encounter other major setbacks in our development or regulatory activities or in our
commercialization efforts, our stock price is likely to decline which would make a future financing more difficult and potentially more dilutive
to our existing stockholders.  For example, after the announcement of the topline results of the Phase 3 MOUNTAIN Study of zuranolone on
December 5, 2019, our stock price declined significantly. Moreover, the terms of any financing may adversely affect the holdings or the rights
of our stockholders.  The issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the
market price of our shares to decline. The incurrence of indebtedness would result in increased fixed payment obligations and we may be
required to agree to certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire,
sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. We
could also be required to seek funds through arrangements with collaborative partners or otherwise at an earlier stage than otherwise would be
desirable and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms
unfavorable to us, any of which may have a material adverse effect on our business, operating results and prospects.

76

 
 
To the extent that we raise additional capital through the sale of common stock or securities convertible or exchangeable into

common stock, the ownership interest of our stockholders in our company will be diluted.  Debt financing, if available, would increase our
fixed payment obligations and may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as
incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaboration, strategic
partnerships and licensing arrangements with third parties, we may have to relinquish valuable rights to our product candidates, our intellectual
property, future revenue streams or grant licenses on terms that are not favorable to us.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue one or more of
our research or development programs or the commercialization of any approved product, or be unable to expand our operations or otherwise
capitalize on our business opportunities, as desired, which could materially affect our business, financial condition and results of operations.

Risks Related to Our Common Stock

Market volatility may affect our stock price and the value of an investment in our stock.

The market price for our common stock, similar to that of other biopharmaceutical companies, is volatile. The market price of our

common stock may fluctuate significantly in response to a number of factors, most of which we cannot control, including, among others:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the results of our commercialization efforts with respect to ZULRESSO, and our ability to attain commercial success;

plans for, progress of, timing of, changes to, delays in or results from clinical trials or non-clinical studies of any of our product
candidates, including positive or negative key data from such studies or clinical trials, serious adverse events arising in the course of
development, or any delays or major announcements related to such studies or trials; and the success or failure of any regulatory
activities with respect to our product candidates;

the impact of the COVID-19 pandemic;

announcements of new products, technologies, commercial relationships, acquisitions, collaborations or other events by us or our
competitors;

the success or failure of our therapies;

regulatory or legal developments in the U.S. and other countries;

adverse developments with respect to our intellectual property portfolio or failure to obtain or loss of exclusivity;

failure of our future product candidates, if successfully developed and approved, to achieve commercial success;

fluctuations in stock market prices and trading volumes of similar companies;

the state of the U.S. and world economies, general market conditions and overall fluctuations in U.S. equity markets, including as a
result of U.S. or world events;

changes in healthcare laws affecting pricing, reimbursement or access;

variations in our quarterly operating results;

changes in our financial guidance or securities analysts’ estimates of our financial performance;

changes in accounting principles;

our ability to raise additional capital and the terms on which we can raise it;

sales of large blocks of our common stock, including sales by our executive officers, directors and significant stockholders;

77

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

additions or departures of key personnel;

discussion of us or our stock price by the press and by online investor communities; and

other risks and uncertainties described in these risk factors.

We have broad discretion in how we use our existing cash and the proceeds from potential future follow-on public offerings, and may not
use such cash and proceeds effectively, which could affect our results of operations and cause our stock price to decline.

We have considerable discretion in the use of our cash and the application of the net proceeds from our follow-on public offerings.

We may use cash and net proceeds for purposes that do not yield a significant return or any return at all for our stockholders. In addition,
pending their use, we may invest the net proceeds from the follow-on offerings in a manner that does not produce income or that loses value.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, even one that may be
beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws may delay or prevent an

acquisition of us or a change in our management.  These provisions include a classified board of directors, a prohibition on actions by written
consent of our stockholders and the ability of our board of directors to issue preferred stock without stockholder approval. In addition, because
we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which limits the
ability of stockholders owning in excess of 15% of our outstanding voting stock to merge or combine with us. Although we believe these
provisions collectively provide for an opportunity to obtain greater value for stockholders by requiring potential acquirers to negotiate with our
board of directors, they would apply even if an offer rejected by our board were considered beneficial by some stockholders. In addition, 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, which is responsible for appointing the members of our management.

Future sales of our common stock may cause our stock price to decline.

Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur could
significantly reduce the market price of our common stock, and impair our ability to raise adequate capital through the sale of additional equity
securities. For example, the 6,241,473 shares of our common stock held by BIMA are subject to an 18-month lockup period, after which BIMA
will be able to sell shares subject to certain sales volume limitations. Following a second 18-month period, BIMA will be able to sell shares
without limitation.

In May 2016, we entered into a lease, as amended in April 2018, under which we rent 40,419 square feet of additional office space in a

separate multi-tenant building in Cambridge, Massachusetts. The term for this lease will expire on August 31, 2024.

We have entered into other non-material leases and may lease additional space prior to the expiration of our leases to meet the needs of

the business.

Item 3. Legal Proceedings

We are not a party to any legal proceedings, and we are not aware of any material claims or actions pending or threatened against us. In

the future, we might from time to time become involved in litigation relating to claims arising from our ordinary course of business, the
resolution of which we do not anticipate would have a material adverse impact on our financial position, results of operations or cash flows.

Operations,” which was filed with the SEC on February 27, 2020.

Overview

We are a biopharmaceutical company committed to developing and commercializing novel medicines with the potential to transform the

lives of people with debilitating disorders of the brain. Our first product, ZULRESSO® (brexanolone) CIV injection, is approved in the U.S.
for the treatment of postpartum depression, or PPD, in adults. We have a portfolio of other product candidates with a current focus on
modulating two critical central nervous system, or CNS, receptor systems, GABA and NMDA. The GABA receptor family, which is
recognized as the major inhibitory neurotransmitter in the CNS, mediates downstream neurologic and bodily function via activation of GABAA
receptors. The NMDA-type receptors of the glutamate receptor system are a major excitatory receptor system in the CNS. Dysfunction in these
systems is implicated in a broad range of CNS disorders. We are currently targeting diseases and disorders of the brain with three key focus
areas: depression, neurology and neuropsychiatry.

Our first product, ZULRESSO, is a proprietary intravenous formulation of brexanolone, approved in the U.S. as a treatment for
postpartum depression, or PPD, in adults. Brexanolone is chemically identical to allopregnanolone, a naturally occurring neuroactive steroid
that acts as a positive allosteric modulator of GABAA receptors. We launched ZULRESSO commercially in the U.S. in June 2019.

Our next most advanced product candidate is zuranolone (SAGE-217), a novel oral compound being developed for certain affective
disorders, including major depressive disorder, or MDD, and PPD.  Zuranolone is a neuroactive steroid that, like brexanolone, is a positive
allosteric modulator of GABAA receptors, targeting both synaptic and extrasynaptic GABAA receptors. We are currently conducting three
Phase 3 placebo-controlled clinical trials of zuranolone – the WATERFALL Study and the CORAL Study in MDD, and the SKYLARK Study
in PPD – as well as an open-label Phase 3 clinical trial in MDD known as the SHORELINE Study. We expect to report topline results from the
WATERFALL Study in the first half of 2021, and topline results from the other zuranolone Phase 3 clinical trials at various times throughout
the remainder of 2021.  

In addition to zuranolone, we have a portfolio of other novel compounds that target GABAA receptors, including SAGE-324.  SAGE-

324 is a novel GABAA receptor positive allosteric modulator intended for chronic oral dosing. We are currently conducting a placebo-
controlled Phase 2 clinical trial evaluating the safety and efficacy of SAGE-324 in the treatment of essential tremor, known as the KINETIC
Study. We expect to report topline data from this study in early

82

 
2021. If the results of the KINETIC Study support further development, we expect to initiate additional development activities including the
next placebo-controlled Phase 2 clinical trial of SAGE-324 in essential tremor in late 2021 to explore dose and frequency, including potential
formulations. We believe SAGE-324 also has potential for the treatment of a number of other neurological conditions, including epilepsy and
Parkinson’s disease.

We are jointly developing zuranolone and SAGE-324 in the U.S. with Biogen MA Inc., or BIMA, and Biogen International GmbH, or,
together with BIMA, Biogen, under a collaboration and license agreement, or the Biogen Collaboration Agreement, that became effective in
December 2020.  Under the Biogen Collaboration Agreement, we will also jointly commercialize products containing zuranolone, which we
refer to as Licensed 217 Products, and products containing SAGE-324, which we refer to as Licensed 324 Products, with Biogen in the U.S. if
our development efforts are successful.  We refer to the Licensed 217 Products and Licensed 324 Products collectively as the Licensed
Products.  In addition, we have granted Biogen sole rights to develop and commercialize the Licensed Products outside the U.S., other than in
Japan, Taiwan and South Korea, or the Existing Partner Territory, where we have granted rights to Shionogi & Co., Ltd., or Shionogi, with
respect to zuranolone.  We refer to the territories outside the U.S. to which Biogen has rights under the Biogen Collaboration Agreement with
respect to the applicable Licensed Product as the Biogen Territory.

Our second area of focus for future clinical development is novel compounds that target the NMDA receptor. The first product candidate

selected for development from this program is SAGE-718, an oxysterol-based positive allosteric modulator of the NMDA receptor, which we
are exploring in certain cognition-related disorders associated with NMDA receptor dysfunction, including cognition dysfunction associated
with diseases such as Huntington’s disease, Parkinson’s disease and Alzheimer’s disease.  We are currently conducting a Phase 2a open-label
study of SAGE-718 evaluating patients with Parkinson’s disease cognitive dysfunction, known as the PARADIGM Study, and a Phase 2a open-
label clinical trial of SAGE-718 in patients with Alzheimer’s disease mild cognitive impairment and mild dementia, known as the LUMINARY
Study. We expect to report topline data from the PARADIGM Study in early 2021 and from the LUMINARY Study in late 2021. We plan to
initiate further development activities including a placebo-controlled Phase 2 clinical trial with SAGE-718 in late 2021 with the indication and
design to be informed by the results of these clinical trials as well as results of an earlier Phase 1 clinical trial in Huntington’s disease.  

We have other compounds at earlier stages of development with a focus on both acute and chronic brain healthy disorders.  Our early-

stage GABAA modulators include SAGE-689, expected to begin Phase 1 development in 2021 as a potential intramuscular therapy for
disorders associated with acute GABA hypofunction, and SAGE-319, intended to be studied as an oral therapy for potential use in disorders of
social interaction. Our early-stage NMDA modulators include SAGE-904, in Phase 1 development as a potential oral therapy for disorders
associated with NMDA hypofunction, and SAGE-421, intended to be studied as a potential oral therapy for certain neurodevelopmental
disorders and cognitive recovery and rehabilitation. We expect to continue our work on allosteric modulation of the GABAA and NMDA
receptor systems in the brain. The GABAA and NMDA receptor systems are broadly accepted as impacting many psychiatric and neurological
disorders, spanning disorders of mood, seizure, cognition, anxiety, sleep, pain, and movement, among others. We believe that we may have the
opportunity to develop molecules from our internal portfolio with the goal of addressing a number of these disorders in the future. We believe
that we may also have the opportunity to use our scientific approach to explore targets beyond the GABAA and NMDA receptor systems and to
develop compounds in areas of unmet need outside of brain health.

We began to generate revenue from product sales in the second quarter of 2019 in conjunction with the launch of our first product,
ZULRESSO in June 2019.  Prior to the second quarter of 2019, all of our revenue had been derived from a strategic collaboration we entered
into in mid-2018 with Shionogi for the clinical development and commercialization of zuranolone in the Existing Partner Territory.  In the
fourth quarter of 2020, we recorded revenue from the strategic collaboration with and stock purchase by Biogen.

We have incurred net losses in each year since our inception, except for net income of $606.1 million for the year ended December 31,

2020, because of revenue recognized under a license and collaboration agreement with Biogen, and we had an accumulated deficit of
$1.0 billion as of December 31, 2020. Our net losses were $680.2 million and $372.9 million for the years ended December 31, 2019 and 2018,
respectively. These losses have resulted principally from costs incurred in connection with research and development activities and selling,
general and administrative costs associated

83

 
 
with our operations and our commercial build. We expect to incur significant expenses and increasing operating losses for the foreseeable
future.

We expect that we will incur significant expenses in the foreseeable future in connection with our ongoing activities, if and as we:  

•

•

•

•

•

•

•

•

•

•

•

•

•

continue to advance Phase 3 clinical development and regulatory activities with respect to zuranolone in PPD and MDD, and
potentially advance zuranolone for other indications, as part of our strategic collaboration with Biogen;

continue our commercialization efforts with respect to ZULRESSO in the treatment of PPD in the U.S., with a primary focus in
geographies that have existing, active ZULRESSO treating sites;

complete the ongoing KINETIC Study in essential tremor, and, if the results support further development, initiate additional
development activities including the next placebo-controlled Phase 2 clinical trial with SAGE-324 in essential tremor to explore
dose and frequency, including potential formulations, with potential future development in epilepsy, Parkinson’s disease, and
other neurological conditions, as part of our strategic collaboration with Biogen;

complete the ongoing Phase 2a open-label PARADIGM Study of patients with Parkinson’s disease cognitive dysfunction and
Phase 2a open-label LUMINARY Study of patients with Alzheimer’s disease mild cognitive impairment and mild dementia, and
initiate planned placebo-controlled Phase 2 clinical trial with indication and design to be determined based on results of completed
and ongoing SAGE-718 clinical trials;

support our collaboration with Biogen with respect to zuranolone and SAGE-324 in the U.S., and support Biogen’s development
of zuranolone and SAGE-324 in Biogen’s licensed territories outside the U.S. and Shionogi’s development of zuranolone in the
Existing Partner Territory;

advance SAGE-689 and SAGE-904 in Phase 1 clinical development, including conducting planned Phase 1 clinical trials;

continue our research and development efforts to evaluate the potential for our existing product candidates in the treatment of
additional indications or in new formulations;

identify new targets, and generate and test new compounds and product candidates, with a focus on indications where we believe
we can make well-informed, rapid go/no-go decisions, with the goal of developing a diversified portfolio of assets with
differentiated features;

prepare and file new drug applications with the U.S. Food and Drug Administration, or FDA, and conduct pre-launch activities
with respect to any of our product candidates that have been successfully developed;

commercialize any product candidates for which we obtain regulatory approval, including the manufacture of commercial
supplies;

at the appropriate time, as our development efforts progress, add personnel, including personnel to support product development
and ongoing and future commercialization efforts;

evaluate the market potential and regulatory pathways for our product candidates beyond zuranolone and SAGE-324 in the
European Union and other countries outside the U.S., and determine how best to move forward where and when it may make
business and strategic sense;

continue to build, maintain, defend, leverage, and expand our intellectual property portfolio, including by utilizing the strengths of
our proprietary chemistry platform and scientific know-how to expand our portfolio of

84

 
 
 
 
 
 
 
 
 
 
 
 
 
 
new chemical entities to lessen our long-term reliance on the success of any one program and to facilitate long-term growth; and

•

continue to explore opportunities to establish agreements or alliances with other pharmaceutical companies, at the appropriate
time, where we believe a collaboration will add significant value to our efforts, including through capabilities, infrastructure,
speed or financial contributions, or to acquire new compounds, product candidates or products if we believe such opportunities
will help us achieve our goals or meet other strategic objectives.

Until such time that we can generate significant revenue from product sales, if ever, we expect to finance our operations primarily
through a combination of revenue, equity or debt financings and other sources, including our collaborations with Biogen, Shionogi, and
potentially, in the future, additional third parties. We may not be successful in our commercialization of ZULRESSO or any other product, and
may not generate meaningful revenue or revenue at the levels or on the timing necessary to support our investment and goals. We may never
successfully complete development of any of our current or future product candidates, obtain necessary regulatory approval for such product
candidates, or achieve commercial viability for any resulting approved product. We may not obtain or maintain adequate patent protection or
other exclusivity for our products or product candidates. Adequate additional financing may not be available to us on acceptable terms, or at
all. Our inability to raise capital if and when needed would have a negative impact on our financial condition and on our ability to pursue our
business strategy. Arrangements with our existing collaborators have required us to relinquish rights to certain of our technologies or product
candidates, and any future collaborations may require us to relinquish additional rights. We will need to generate significant revenue to achieve
profitability, and we may never do so.

We expect that our existing cash, cash equivalents and marketable securities as of December 31, 2020, will enable us to fund our
operating expenses and capital expenditure requirements, based on our current operating plan, for at least the next 12 months from the filing
date of this Annual Report. See “—Liquidity and Capital Resources”.

Financial Operations Overview

Revenue

We began to generate revenue from product sales in the second quarter of 2019 in conjunction with the launch of our first product,

ZULRESSO in June 2019. Prior to the second quarter of 2019, all of our revenue had been derived from a strategic collaboration we entered
into in mid-2018 with Shionogi.  

Our revenue from sales of ZULRESSO has been negatively impacted by significant barriers arising from the complex requirements for

treatment, and, more recently, by the spread of COVID-19 in the U.S.  ZULRESSO is administered as a continuous infusion given over two
and a half days. Because of the risk of serious harm resulting from excessive sedation or sudden loss of consciousness during the ZULRESSO
infusion, ZULRESSO must be administered only in a medically-supervised healthcare setting that has been certified under a REMS program
and meets the other requirements of the REMS program, including requirements related to monitoring of the patient during the infusion.  The
actions required for a healthcare setting to be ready and willing to treat women with PPD are complex and time-consuming.  These actions
include: becoming REMS-certified; achieving formulary approvals; establishing protocols for administering ZULRESSO; and securing
satisfactory reimbursement. Sites must often negotiate reimbursement on a payor-by-payor basis under commercial coverage.  These
requirements have created significant barriers to treatment, and are expected to continue to limit future revenue growth. These barriers have
been compounded by the COVID-19 pandemic.  The spread of COVID-19 in the U.S. has resulted in a significant number of sites of care
pausing treatment of new patients with ZULRESSO and potential new sites of care pausing site activation activities.  We believe concerns
about exposure to the virus have also caused a significant reduction in the number of women with PPD seeking treatment with ZULRESSO
and in physicians willing to prescribe it. Given the continuing concerns about the COVID-19 pandemic across the country, we expect
the significant adverse impact of the pandemic on ZULRESSO revenues to continue. We anticipate that the COVID-19 pandemic will also
continue to have an adverse impact on our results of operations from sales of ZULRESSO as pandemic-related restrictions are expected to
continue to be in effect for the foreseeable future. The scope and timing of the expected negative impact will depend on, among other factors,
the

85

 
 
 
duration and severity of precautionary measures taken to curb the spread of COVID-19, the length, location and frequency of surges or waves
of COVID-19 cases and the timing and success of the roll-out of vaccines for COVID-19 and any return to normal business operations across
the U.S.

In April 2020, we implemented a workforce reduction that primarily affected the ZULRESSO commercial operation and related support

functions, including eliminating the entirety of our salesforce at that time. While we remain committed to working with healthcare providers
and women with PPD seeking access to ZULRESSO and plan to continue to evaluate opportunities to raise awareness and help reduce hurdles
to appropriate treatment, our ongoing commercial efforts, including our small account management field-based team and a small number of
sales representatives, are primarily focused on geographies that have existing, active ZULRESSO treating sites. We expect that this approach to
our commercial efforts may continue to substantially limit the revenue opportunity for ZULRESSO.

We expect that ZULRESSO revenues are likely to fluctuate quarter to quarter. We will not generate revenue from other products unless

and until we or any of our collaborators successfully develop, obtain regulatory approval of, and commercialize one of our current or future
product candidates.  If we enter into additional collaboration agreements with third parties for our product candidates, we may generate
revenue from those collaborations. We expect that revenue, if any, that we may generate under our collaboration agreements will fluctuate from
quarter to quarter as a result of the timing and amount of license fees, payments for clinical materials or manufacturing services, milestone
payments, royalties paid to us and our share of collaboration profits or losses resulting from sales of any commercialized products, and other
payments.

In June 2018, we entered into a strategic collaboration with Shionogi for the clinical development and commercialization of zuranolone

for the treatment of MDD and other potential indications in the Existing Partner Territory. Under the terms of the agreement, Shionogi is
responsible for all clinical development, regulatory filings and commercialization and manufacturing of zuranolone for MDD, and potentially
other indications, in the Existing Partner Territory. In October 2018, we also entered into a supply agreement with Shionogi for zuranolone
clinical material. To date, revenue from our collaboration with Shionogi has come from an initial, upfront license fee upon execution of the
collaboration agreement of $90.0 million, which was recorded as collaboration revenue in the year ended December 31, 2018, and for the
supply of active pharmaceutical agreement, or API, for Shionogi’s clinical trials.

In November 2020, we entered into the Biogen Collaboration Agreement with Biogen for the development, manufacture and
commercialization of the Licensed Products. In connection with the execution of the Biogen Collaboration Agreement, we also entered into a
stock purchase agreement for the sale and issuance to BIMA of 6,241,473 shares of our common stock. The Biogen Collaboration Agreement
became effective on December 28, 2020, and the sale of the common stock under the stock purchase agreement closed on December 31, 2020.
Under the terms of the Biogen Collaboration Agreement we will jointly develop and commercialize the Licensed Products in the U.S., and
Biogen solely will develop and commercialize the Licensed Products in the Biogen Territory, except, with respect to the Licensed 217
Products, in the Existing Partner Territory. We and Biogen have agreed to share equally all costs for activities under the Biogen Collaboration
Agreement solely for the U.S. Biogen is solely responsible for all costs for activities under the Biogen Collaboration Agreement in the Biogen
Territory. In the year ended December 31, 2020, we recorded collaboration revenue of $1.1 billion, consisting of an upfront payment of $875.0
million plus $232.5 million in excess proceeds from the equity investment under the stock purchase agreement, when measured at fair value.

Cost of goods sold

Cost of goods sold includes direct and indirect costs related to the manufacturing and distribution of ZULRESSO, including third-party

manufacturing costs, packaging services, freight, third-party royalties payable on our net product revenues and amortization of intangible assets
associated with ZULRESSO. We estimate that our cost of goods sold as a percentage of net product revenue will remain in the mid-single digit
percentage range for the foreseeable future. We expect to utilize zero-cost inventory with respect to ZULRESSO for an extended period of
time.

86

 
 
 
 
Operating Expenses

Our operating expenses since inception have consisted primarily of costs associated with research and development activities and

selling, general and administrative activities.

Research and Development Expenses

Research and development expenses, which consist primarily of costs associated with our product research and development efforts, are

expensed as incurred. Research and development expenses consist primarily of:

•

•

•

•

•

•

•

personnel costs, including salaries, benefits, stock-based compensation and travel expenses, for employees engaged in research
and development functions;

expenses incurred under agreements with contract research organizations, or CROs, and sites that conduct our non-clinical studies
and clinical trials;

expenses associated with manufacturing materials for use in non-clinical studies and clinical trials and developing external
manufacturing capabilities;

costs of outside consultants engaged in research and development activities, including their fees and travel expenses;

other expenses related to our non-clinical studies and clinical trials and expenses related to our regulatory activities;

payments made under our third-party license agreements; and

a portion of our information technology, facilities and other related expenses, including rent, depreciation, maintenance of
facilities, insurance and supplies.

Costs for certain development activities are recognized based on an evaluation of the progress to completion of specific tasks using

information and data provided to us by our vendors and our clinical sites.

We have been developing our product candidates and focusing on other research and development programs, including exploratory

efforts to identify new compounds, target validation for identified compounds and lead optimization for our earlier-validated programs. Our
direct research and development expenses are tracked on a program-by-program basis, and consist primarily of external costs, such as fees paid
to investigators, central laboratories, CROs and contract manufacturing organizations, in connection with our non-clinical studies and clinical
trials; third-party license fees related to our product candidates; and fees paid to outside consultants who perform work on our programs. We do
not allocate employee-related costs and other indirect costs to specific research and development programs because these costs are deployed
across multiple product programs under research and development and, as such, are separately classified as unallocated or stock-based
compensation in research and development expenses.

Research and development activities are central to our business. Product candidates in later stages of clinical development generally
have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-
stage clinical trials. We expect that our research and development expenses will continue to increase in the foreseeable future as we continue or
initiate clinical trials and non-clinical studies for certain product candidates and pursue later stages of clinical development of our product
candidates.

We cannot determine with certainty the duration and costs of the current or future clinical trials of our product candidates. The duration,

costs, and timing of clinical trials and development of our product candidates will depend on a variety of factors, including:

•

•

•

the scope, size, rate of progress, and expense of our ongoing as well as any additional clinical trials, non-clinical studies, and other
research and development activities;

future results of ongoing, planned or future clinical trials and non-clinical studies;

decisions by regulatory authorities related to our product candidates;

87

 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

uncertainties in clinical trial enrollment rate or design;

significant and changing government regulation; and

the receipt and timing of regulatory approvals, if any.

In addition, the ongoing COVID-19 pandemic may also negatively impact our ongoing and planned development activities and increase

our research and development costs.  Concerns, precautions and restrictions arising from the COVID-19 pandemic may substantially slow
clinical site recruitment and initiation and enrollment in our clinical trials, may impair the conduct, auditing, monitoring, or completion of our
trials, may impair or impede the timeliness and completion of our data collection and analysis efforts or the integrity of our data, or may cause
us to pause trials, in each case which may significantly impact our ability to meet our expected timelines or cause us to change our plans and
may significantly increase our research and development costs. For example, we have seen some slower recruitment in certain of our clinical
trials, especially with respect to older patients.

A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant
change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory
authority were to require us to conduct clinical trials beyond those that we currently anticipate will be required for the completion of clinical
development of a product candidate or for regulatory approval, or if we experience significant delays in enrollment in any of our clinical trials
or need to enroll additional patients, we could be required to expend significant additional financial resources and time on the completion of
clinical development.

Any failure to complete any stage of the development of any potential product candidates in a timely manner could have a material

adverse effect on our operations, financial position and liquidity. A discussion of some of the risks and uncertainties associated with not
completing our programs on schedule, or at all, and the potential consequences of failing to do so, are set forth in Part I, Item 1A, “Risk
Factors”.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of personnel costs, including salaries, benefits and travel expenses for our

executive, finance, business, commercial, corporate development and other administrative functions, and stock-based compensation expense.
Selling, general and administrative expenses also include professional fees for expenses incurred under agreements with third parties relating to
the commercialization of ZULRESSO; public relations, audit, tax and legal services, including legal expenses to pursue patent protection of
our intellectual property; and a portion of our information technology, facilities and other related expenses, including rent, depreciation,
maintenance of facilities, insurance and supplies.

In April 2020, we implemented a workforce reduction that primarily affected the ZULRESSO commercial operation and related support

functions, including eliminating the entirety of our salesforce at that time. While we remain committed to working with healthcare providers
and women with PPD seeking access to ZULRESSO and plan to continue to evaluate opportunities to raise awareness and help reduce hurdles
to appropriate treatment, our ongoing commercial efforts, including our small account management field-based team and a small number of
sales representatives, are primarily focused on geographies that have existing, active ZULRESSO treating sites.  Even with the expected
reduction in selling, general and administrative expenses as a result of the restructuring, we expect to continue to incur significant
commercialization expenses, including payroll and related expenses, to support our ongoing commercial activities associated with
ZULRESSO.  We expect that selling, general and administrative expenses will increase in the future if we are successful in our development
efforts and are preparing for potential commercialization of our current or future product candidates, if approved. We expect to continue to
incur significant expenses associated with general operations, including costs related to accounting and legal services, director and officer
insurance premiums, facilities and other corporate infrastructure and office-related costs, such as information technology costs.

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the U.S. The

preparation of our consolidated financial statements and related disclosures requires us to make estimates and assumptions that affect the
reported amount of assets, liabilities, revenue, costs and expenses, and related disclosures. We believe that the estimates and assumptions
involved in the accounting policies described below may have the greatest potential impact on our consolidated financial statements and,
therefore, consider these to be our critical accounting policies. We evaluate our estimates and assumptions on an ongoing basis. Our actual
results may differ from these estimates under different assumptions and conditions. While our significant accounting policies are described in
more detail in the notes to our consolidated financial statements appearing elsewhere in this Annual Report, we believe that the following
accounting policies are those most critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

We generate revenue from the sale of our product, ZULRESSO, which was approved by the FDA in March 2019 and we subsequently

began selling in June 2019, and from collaboration and supply agreements with our collaborators. To date, revenue from our collaboration
agreements has come from initial, upfront consideration allocated to licenses of intellectual property, and from the supply of material for
clinical trials under a supply agreement.

Under Accounting Standards Codification, or ASC, Topic 606, “Revenue from Contracts with Customers”, or Topic 606, an entity
recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity
expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are
within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the
performance obligations in the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the
transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance
obligation. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally
considered options. We assess if these options provide a material right to the customer and if so, they are considered performance obligations.
The exercise of a material right may be accounted for as a contract modification or as a continuation of the contract for accounting purposes.

For contracts determined to be within the scope of Topic 606, we assess whether the goods or services promised within each contract are

distinct to identify those that are performance obligations. This assessment involves subjective determinations and requires management to
make judgments about the individual promised goods or services and whether such are separable from the other aspects of the contractual
relationship. Promised goods and services are considered distinct provided that: (i) the customer can benefit from the good or service either on
its own or together with other resources that are readily available to the customer and (ii) the entity’s promise to transfer the good or service to
the customer is separately identifiable from other promises in the contract.

We allocate the transaction price (the amount of consideration we expect to be entitled to from a customer in exchange for the promised
goods or services) to each performance obligation and recognize the associated revenue when (or as) each performance obligation is satisfied.
Our estimate of the transaction price for each contract includes all variable consideration to which we expect to be entitled.

Collaboration and license revenue

In assessing whether a promised good or service is distinct in the evaluation of a collaboration or license arrangement subject to Topic

606, we consider factors such as the research, manufacturing and commercialization capabilities of the collaboration partner and the
availability of the associated expertise in the general marketplace. We also consider the intended benefit of the contract in assessing whether a
promised good or service is separately identifiable from other promises in the contract. If a promised good or service is not distinct, we are
required to combine that good or service with other promised goods or services until we identify a bundle of goods or services that is distinct.

89

 
 
 
 
The transaction price is then determined and allocated to the identified performance obligations in proportion to their standalone selling

prices, or SSP, on a relative SSP basis. SSP is determined at contract inception and is not updated to reflect changes between contract inception
and when the performance obligations are satisfied. Determining the SSP for performance obligations requires significant judgment. In
developing the SSP for a performance obligation, we consider applicable market conditions and relevant entity-specific factors, including
factors that were contemplated in negotiating the agreement with the customer and estimated costs.  In certain circumstances, we may apply the
residual method to determine the SSP of a good or service if the standalone selling price is considered highly variable or uncertain. We validate
the SSP for performance obligations by evaluating whether changes in the key assumptions used to determine the SSP will have a significant
effect on the allocation of arrangement consideration between multiple performance obligations.

If the consideration promised in a contract includes a variable amount, we estimate the amount of consideration to which we will be
entitled in exchange for transferring the promised goods or services to a customer. We determine the amount of variable consideration by using
the expected value method or the most likely amount method. We include the unconstrained amount of estimated variable consideration in the
transaction price. The amount included in the transaction price is constrained to the amount for which it is probable that a significant reversal
of cumulative revenue recognized will not occur. At the end of each subsequent reporting period, we re-evaluate the estimated variable
consideration included in the transaction price and any related constraint, and if necessary, adjust our estimate of the overall transaction price.
Any such adjustments are recorded on a cumulative catch-up basis in the period of adjustment.

If an arrangement includes development and regulatory milestone payments, we evaluate whether the milestones are considered probable

of being reached and estimate the amount to be included in the transaction price using the most likely amount method. If it is probable that a
significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are
not within our control or the licensee’s control, such as regulatory approvals, are generally not considered probable of being achieved until
those approvals are received.

In determining the transaction price, we adjust consideration for the effects of the time value of money if the timing of payments
provides us with a significant benefit of financing. We do not assess whether a contract has a significant financing component if the expectation
at contract inception is such that the period between payment by the licensees and the transfer of the promised goods or services to the
licensees will be one year or less. We assessed our arrangements with Shionogi and Biogen and concluded that a significant financing
component does not exist in either arrangement. For arrangements with licenses of intellectual property that include sales-based royalties,
including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, we
recognize royalty revenue and sales-based milestones at the later of (i) when the related sales occur, or (ii) when the performance obligation to
which the royalty has been allocated has been satisfied.

We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as)
each performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method.
Revenue from our collaboration agreement with Shionogi has come from initial, upfront consideration that was allocated to the license of
zuranolone and for the supply of drug product for Shionogi clinical trials. Revenue from our collaboration agreement with Biogen has come
from initial, upfront consideration that was allocated to the licenses for the Licensed 217 Products and the Licensed 324 Products. For
additional information, refer to Note 6, Collaboration Agreements, to our consolidated financial statements appearing elsewhere in this Annual
Report.

Product revenue

We recognize product revenues, net of variable consideration related to certain allowances and accruals that are determined using the

expected value method, in our consolidated financial statements at the point in time when control transfers to the customer, which is typically
when the product has been delivered to the customer’s location. The amount included in the transaction price is constrained to the amount for
which it is probable that a significant reversal of cumulative revenue recognized will not occur. Our only performance obligation identified for
ZULRESSO is to deliver the product to the location specified by the customer’s order. We record shipping and handling costs associated with
delivery of product to our customers within selling, general and administrative expenses on our consolidated statements of operations and
comprehensive income (loss). We expense incremental costs of obtaining a contract as incurred if the

90

 
 
expected amortization period of the asset would be less than one year. If we were to incur incremental costs with an amortization period greater
than a year, such costs would be capitalized as contract assets, as they are expected to be recovered, and would be expensed by amortizing on a
systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. We did not have any
contract assets (unbilled receivables) at December 31, 2020, as customer invoicing generally occurs before or at the time of revenue
recognition. We did not have any contract liabilities at December 31, 2020, as we did not receive any payments in advance of satisfying our
performance obligations to our customers. Amounts billed or invoiced are included in prepaid expenses and other current assets on the
consolidated balance sheets.

We record reserves, based on contractual terms, for the following components of variable consideration related to product sold during

the reporting period, as well as our estimate of product that remains in the distribution channel inventory of our customers at the end of the
reporting period. On a quarterly basis, we will update our estimates and record any necessary material adjustments in the period they are
identified.

Chargebacks: We estimate chargebacks from our customers who directly purchase the product from us for discounts resulting from
contractual commitments to sell products to eligible healthcare settings at prices lower than the list prices charged to our customers.
Customers charge us for the difference between what they pay to us for the product and the selling price to the eligible healthcare
settings. Reserves for chargebacks consist of credits that we expect to issue for units that remain in the distribution channel
inventories at the end of each reporting period that we expect will be sold to eligible healthcare settings, and chargebacks that
customers have claimed, but for which we have not yet issued a credit.

Government Rebates: We are subject to discount obligations under government programs, including Medicaid. We record reserves for
rebates in the same period the related product revenue is recognized, resulting in a reduction of ZULRESSO product revenues and a
current liability that is included in accrued expenses on our consolidated balance sheets.  Our liability for these rebates consists of
invoices received for claims from prior quarters that have not been paid or for which an invoice has not yet been received, estimates
of claims for the current quarter, and estimates of future claims that will be made for product that has been recognized as revenue, but
which remains in the distribution channel at the end of each reporting period.

Trade Discounts and Allowances: We generally provide customary invoice discounts on ZULRESSO sales to our customers for
prompt payment and we pay fees for sales order management, data, and distribution services. We estimate our customers will earn
these discounts and fees and deduct these discounts and fees in full from gross ZULRESSO revenues and accounts receivable at the
time we recognize the related revenues.

Financial Assistance: We provide voluntary financial assistance programs to patients with commercial insurance that have coverage
and reside in states that allow financial assistance. We estimate the financial assistance amounts for ZULRESSO and record any such
amounts within accrued expenses on the consolidated balance sheets. The calculation of the accrual for financial assistance is based
on an estimate of claims and the cost per claim that the we expect to receive using demographics for patients who have registered and
been approved for assistance. Any adjustments are recorded in the same period the related revenue is recognized, resulting in a
reduction of product revenue and the establishment of a current liability, which is included as a component of accrued expenses on
the consolidated balance sheets.

Product Returns: Consistent with industry practice, we offer product return rights to direct customers for damaged, defective or
expiring product, provided it is within a specified period around the product expiration date as set forth in our return goods policy. We
estimate the amount of our product sales that may be returned by our customers and record this estimate as a reduction of revenue in
the period the related product revenue is recognized, as well as a reserve within accrued expenses on our consolidated balance sheets.
We have experienced no product returns to date. We will update our estimated refund liability, on at least a quarterly basis, based on
actual shipments of ZULRESSO subject to contractual return rights, changes in expectations about the amount of estimated refunds
or actual returns.

91

 
 
 
 
 
 
 
 
Collaborative arrangements

We analyze our collaboration arrangements to assess whether such arrangements involve joint operating activities performed by parties

that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such
activities and therefore within the scope of ASC Topic 808, Collaborative Arrangements, or Topic 808. This assessment is performed
throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. For collaboration arrangements
within the scope of Topic 808 that contain multiple elements, we first determine which elements of the collaboration are deemed to be within
the scope of Topic 808 and which elements of the collaboration are more reflective of a vendor-customer relationship and therefore within the
scope of Topic 606. For elements of collaboration arrangements that are accounted for pursuant to Topic 808, an appropriate recognition
method is determined and applied consistently, either by analogy to authoritative accounting literature or by applying a reasonable and rational
policy election. For those elements of the arrangement that are accounted for pursuant to Topic 606, we apply the five-step model described
above.

Accrued Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and

development expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel and vendors to
identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the
services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our service providers invoice us in
arrears for services performed, on a pre-determined schedule or when contractual milestones are met; however, some require advance
payments. We make estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and
circumstances known to us at that time. Examples of estimated accrued research and development expenses include fees paid to:

•

•

•

•

CROs in connection with performing research and development services on our behalf;

other providers in connection with clinical trials;

vendors in connection with non-clinical development activities; and

vendors related to product manufacturing, development and distribution of clinical supplies.

We base our expenses related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts with

multiple CROs that conduct and manage clinical trials on our behalf. The financial terms of these agreements vary from contract to contract
and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services
provided and result in a prepayment of the clinical expense. Payments under some of these contracts depend on factors such as the successful
enrollment of patients and the completion of clinical trial milestones. When determining accruals, we estimate the time period over which
services will be performed, enrollment of patients, number of sites activated and level of effort to be expended in each period. If the actual
timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid accordingly. Although we
do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services
performed relative to the actual status and timing of services performed may vary and may result in reporting expenses that are too high or too
low in any particular period. To date, we have not made any material adjustments to our prior estimates of accrued research and development
expenses.

Stock-Based Compensation

We recognize compensation expense for stock-based awards, including grants of stock options and restricted stock units, made to
employees and non-employee directors based on the estimated fair value on the date of grant, over the requisite service period. We recognize
stock-based compensation expense for only the portion of awards that are expected to vest.

For awards that vest upon achievement of a performance condition, we recognize compensation expense when achievement of the
performance condition is met or during the period from which meeting the condition is deemed probable until the expected date of meeting the
performance condition.

92

 
 
 
 
 
 
 
We have historically granted stock options with exercise prices equivalent to the fair value of our common stock as of the date of
grant.  For grants of restricted stock units, we base the fair value on the stock price as of the date of grant. Prior to January 1, 2019, the majority
of our grants were stock options. Effective January 1, 2019, for grants to employees, we began to grant a mix of stock options and restricted
stock units.

Effective January 1, 2019, we recognize compensation expense for stock-based awards made to non-employee consultants based on the
estimated fair value on the date of grant, over the requisite service period.  Through December 31, 2018, we recognized compensation expense
for stock-based awards granted to non-employee consultants based on the fair value of the awards on each date on which the awards vest.
Compensation expense was recognized over the vesting period, provided that services were rendered by such non-employee consultants during
that time. At the end of each financial reporting period, the fair value of unvested options was re-measured using the then-current fair value of
our common stock and updated assumptions using the Black-Scholes option-pricing model.

The fair value of each option grant is estimated using the Black-Scholes option-pricing model. For the years ended December 31, 2019
and 2018, we estimated our expected volatility using a weighted average of the historical volatility of publicly-traded peer companies and the
volatility of our common stock. Effective January 1, 2020, the Company began using the historical volatility of only our common stock, as
there is adequate historical data for the duration of the expected term.

The expected term of the options granted to employees and non-employee directors by us has been determined utilizing the “simplified”

method for awards that qualify as “plain-vanilla” options. Through December 31, 2018, the expected term of our options granted to non-
employee consultants was determined based on the contractual term of the options, and since January 1, 2019, the “simplified” method has
been used. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for
time periods approximately equal to the expected term of the award. The expected dividend yield is based on the fact that we have never paid
cash dividends and do not expect to pay any cash dividends in the foreseeable future.

The fair value of each stock option granted under our equity plans has been calculated on the date of grant using the following weighted

average assumptions:

Expected dividend yield
Expected volatility
Risk-free interest rate
Expected term

These assumptions represented our best estimates, but the estimates involve inherent uncertainties and the application of our judgment.

As a result, if factors change and we use significantly different assumptions or estimates when valuing our stock options, our stock-based
compensation expense could be materially different. In developing a forfeiture rate estimate for pre-vesting forfeitures, we have considered our
historical experience of actual forfeitures. If our future actual forfeiture rate is materially different from our estimate, our stock-based
compensation expense could be significantly different from what we have recognized in the current period.

At December 31, 2020, we had unrecognized stock-based compensation expense related to our unvested time-based stock option awards

of $120.5 million, which is expected to be recognized over the remaining weighted average vesting period of 1.76 years.

At December 31, 2020, 288,575 performance-based stock options were both outstanding and unvested, and the total unrecognized stock-

based compensation expense related to those awards was $20.6 million.

At December 31, 2020, 957,695 restricted stock units were both outstanding and unvested, and the total unrecognized stock-based

compensation expense related to those awards was $58.2 million.

Product revenue, net

During the years ended December 31, 2020 and 2019, we recognized $6.7 million and $4.0 million, respectively, of net product revenues

related to sales of ZULRESSO. Sales allowances and accruals consisted of patient financial assistance, distribution fees, discounts, and
chargebacks.

Collaboration revenue

During the year ended December 31, 2020, we recognized collaboration revenue of $1.1 billion related to the execution of the Biogen

Collaboration Agreement and the Biogen stock purchase agreement. The revenue consisted of an upfront payment of $875.0 million plus
$232.5 million in excess proceeds from the equity investment under the stock purchase agreement that was allocated to the licenses for the
Licensed 217 Products and the Licensed 324 Products delivered to Biogen in December 2020.

During the year ended December 31, 2020, we recognized no collaboration revenue from our agreement with Shionogi. During the year

ended December 31, 2019, we recognized $2.9 million in collaboration revenue from our agreement with Shionogi related to the supply of
zuranolone API for clinical development.

We expect that revenue, if any, that we may generate under our collaboration agreements will fluctuate from quarter to quarter as a result

of the timing and amount of license fees, payments for clinical materials or manufacturing services, milestone payments, royalties paid to us
and our share of collaboration profits or losses resulting from sales of any commercialized products, and other payments.

collaboration agreements, refer to Note 6, Collaboration Agreements appearing elsewhere and Note 2,

Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements, appearing elsewhere in this Annual Report.

Cost of goods sold

During the years ended December 31, 2020 and 2019, cost of goods sold was $0.6 million and $0.4 million, respectively, and is made up

of a low-single digit royalty cost on net product revenue to CyDex Pharmaceuticals, Inc. and The Regents of the University of California, or
the Regents, the amortization of intangible assets associated with ZULRESSO and third-party manufacturing and distribution costs associated
with labeling, packaging, and shipping of ZULRESSO. Prior to receiving initial FDA approval for ZULRESSO on March 19, 2019, we
manufactured ZULRESSO inventory to be sold upon commercialization and recorded approximately $8.9 million related to this inventory
build-up as research and development expense. As a result, the manufacturing costs related to the ZULRESSO inventory build-up incurred
before FDA approval were already expensed in a prior period and are therefore excluded from the cost of goods sold for the years ended
December 31, 2020 and 2019. We estimate that our cost of goods sold as a percentage of net product revenue will remain in the mid-single
digit percentage range for the foreseeable future. We expect to utilize zero-cost inventory with respect to ZULRESSO for an extended period of
time.

Research and development expenses for the year ended December 31, 2020 were $292.7 million, compared to $368.8 million for the

year ended December 31, 2019. The decrease of $76.1 million was primarily due to the following:

•

•

•

•

•

a decrease of $30.2 million in expenses for zuranolone, primarily as a result of completion of the MOUNTAIN Study and
decreased spending for clinical pharmacology studies, partially offset by an increase in spending for the WATERFALL Study and
the SKYLARK Study;

a decrease of $2.0 million in expenses for SAGE-324, primarily due to the completion of Phase 1 clinical trials while the initiation
of Phase 2 clinical trials did not occur until mid- to late 2020;

a decrease of $5.5 million in expenses for SAGE-718, primarily due to the completion of Phase 1 clinical trials in 2019 while the
initiation of Phase 2 clinical trials did not occur until mid- to late 2020;

a decrease of $15.0 million in expenses for other research and development programs, related to a decrease in spending on non-
clinical studies; and

a decrease of $20.6 million in non-cash stock-based compensation expense. There was no non-cash stock-based compensation
expense recognized related to the achievement of performance-based vesting criteria during the year ended December 31, 2020.
The amount of non-cash stock-based compensation expense related to the achievement of performance-based vesting criteria was
$14.0 million for the year ended December 31, 2019. The remainder of the decrease is primarily from the impact of the
cancellation of option grants that had been made to terminated employees, including those terminated in the April 2020
restructuring.

Selling, general and administrative expenses for the years ended December 31, 2020 and 2019 were $197.0 million and $345.8 million,

respectively.  The decrease of $148.8 million was primarily due to the following:

•

•

•

•

a decrease of $64.5 million in personnel-related costs, mainly as a result of the termination of employees in the April 2020
restructuring;

a decrease of $38.5 million in non-cash stock-based compensation expense. There was no non-cash stock-based compensation
expense recognized related to the achievement of performance-based vesting criteria during the year ended December 31,
2020.  The amount of non-cash stock-based compensation expense related to the achievement of performance-based vesting
criteria was $13.2 million during the year ended December 31, 2019. The remainder of the decrease is primarily from the impact
of the cancellation of option grants that had been made to terminated employees, including those terminated in the April 2020
restructuring;

a decrease of $26.1 million in professional fees, primarily due to costs incurred in the year ended December 31, 2019, related to
preparations for the commercial launch of ZULRESSO in the U.S. in June 2019 and the impact of the April 2020 restructuring on
our spending for commercial activities; and

a decrease of $19.8 million in other costs, primarily due to the impact of the April 2020 restructuring and the impact of the
COVID-19 pandemic resulting in our employees working remotely and a reduction in business travel.

Restructuring

In April 2020, we announced a restructuring plan to enable us to advance our corporate strategy and pipeline that included the
elimination of approximately 53% of our workforce. The workforce reduction primarily affected the ZULRESSO commercial operation and
related selling, general and administrative support functions. In the year ended December 31, 2020, we recorded $27.7 million of expense for
restructuring, primarily for one-time termination benefits to the affected employees, primarily for cash payments of severance, healthcare
benefits and outplacement assistance.

Interest income, net and Other income, net

Interest income, net, and other income, net, for the years ended December 31, 2020 and 2019 were $9.8 million and $27.9 million,

respectively. The primary reason for the decrease was the decrease in the balance of marketable securities, along with a reduction in interest
rates. The payments of $1.5 billion that were received from Biogen on December 31, 2020, $875.0 million of which was an upfront payment
and $650.0 of which was received in exchange for shares of our common stock, were in cash and cash equivalents in the balance sheet as of
December 31, 2020.

Liquidity and Capital Resources

Prior to the second quarter of 2019, we had not generated revenue from product sales.  We began to generate revenue from product sales

in the second quarter of 2019 in conjunction with the launch of our first product, ZULRESSO, in June 2019.  Prior to the second quarter of
2019, all of our revenue had been derived from our collaboration with Shionogi. To date, we have incurred recurring net losses, except for net
income of $606.1 million for the year ended December 31, 2020, because of revenue recognized under a license and collaboration agreement
with Biogen. As of

December 31, 2020, we had an accumulated deficit of $1.0 billion. From our inception through December 31, 2020, we have received
aggregate net proceeds of $2.8 billion from the sales of redeemable convertible preferred stock prior to our initial public offering, the issuance
of convertible notes, and the sales of common stock in our initial public offering in July 2014, follow-on offerings and the sale of stock to
Biogen.  We also received $1.0 billion in upfront payments under our collaborations with Biogen and Shionogi.

On February 27, 2019, we completed the sale of 3,833,334 shares of our common stock in a follow-on underwritten public offering at a

price to the public of $150.00 per share, resulting in net proceeds of $560.9 million after deducting commissions and underwriting discounts
and offering costs paid by us.

As described below, on December 31, 2020, we completed the sale of 6,241,473 shares of our common stock in a private placement to

Biogen at a price to the public of approximately $104.14 per share, resulting in aggregate gross proceeds of $650.0 million.

As of December 31, 2020, our primary sources of liquidity were our cash, cash equivalents and marketable securities, which totaled $2.1

billion. We invest our cash in money market funds, U.S. government securities, corporate bonds and commercial paper, and our primary
objectives are to preserve principal, provide liquidity and maximize income without significantly increasing risk.

The following table summarizes the primary sources and uses of cash for the years ended December 31, 2020 and 2019:

During the year ended December 31, 2020, net cash used in operating activities primarily resulted from our net income of $606.1

million, which was primarily attributable to collaboration revenue from our collaboration with Biogen, partially offset by our research and
development activities and our selling, general and administrative expenses, along with changes in our operating assets and liabilities of $39.7
million, partially offset by $97.9 million of non-cash items.  During the year ended December 31, 2019, net cash used in operating activities
primarily resulted from our net loss of $680.2 million, which was primarily attributable to our research and development activities and our
selling, general and administrative expenses, partially offset by changes in our operating assets and liabilities of $6.7 million and $144.9
million of non-cash items.

Investing Activities

During the years ended December 31, 2020 and 2019, net cash provided by investing activities was $442.7 million and net cash used in

investing activities was $143.2 million, respectively.  During the years ended December 31, 2020 and 2019, we purchased marketable
securities and had sales and maturities of our marketable securities as part of managing our cash and investments portfolio.  

Financing Activities

During the years ended December 31, 2020 and 2019, net cash provided by financing activities was $426.8 million and $607.6 million,

respectively. During the year ended December 31, 2020, we received $650.0 million of proceeds from our sale of 6,241,473 shares of our
common stock to Biogen under the stock purchase agreement, of which $417.5 million

was recorded as equity and the remainder was recorded as revenue. During the year ended December 31, 2019, we received $560.9 million of
net proceeds from our follow-on underwritten public offering, after deducting commissions and underwriting discounts and offering costs paid
by us.

Operating Capital Requirements

We began to generate revenue from product sales in the second quarter of 2019 in conjunction with the launch of our first product,
ZULRESSO.  We anticipate that we will continue to generate losses for the foreseeable future, and we expect the losses to increase as we
continue the development of our current and future product candidates, and seek regulatory approvals for those product candidates that are
successfully developed; prepare for potential future commercialization of product candidates beyond ZULRESSO that are successfully
developed and approved; begin to commercialize any such products, if successfully developed and approved; and continue our efforts to
identify and develop new product candidates beyond our current portfolio. We also expect to incur significant costs associated with general
operations. In addition, we expect to incur significant commercialization expenses for product sales, marketing and outsourced manufacturing
with respect to ZULRESSO and any future products that are successfully developed and approved. Accordingly, we anticipate that we will
need substantial additional funding in connection with our continuing operations.

Based on our current operating plans, we expect that our existing cash, cash equivalents and marketable securities as of December 31,

2020, will enable us to fund our operating expenses and capital expenditure requirements for at least the next 12 months from the filing date of
this Annual Report. During that time, we expect to incur significant expenses as we continue to develop and commercialize our product and
product candidates and pursue our strategic plan.

Our current operating plan does not contemplate other development activities that we may pursue or that all of our currently planned
activities will proceed at the same pace, or that all of these activities will be fully initiated or completed during that time. We have based our
estimates on assumptions that could change, and we may use our available capital resources sooner than we currently expect. We may also
choose to change or increase our development, commercialization or other efforts. Because of the numerous risks and uncertainties associated
with the development and commercialization of any product or product candidates, we are unable to estimate the amounts of increased capital
outlays and operating expenditures necessary to complete development of our current or future product candidates or to commercialize any
approved product.

Our future capital requirements will depend on many factors, including:

•

•

•

•

the amount and timing of revenues from sales of ZULRESSO, which will be impacted by a number of factors, including: the rate,
degree and level of market acceptance for ZULRESSO for the treatment of PPD in the U.S.; the impact of our April 2020
restructuring and the decision to focus our efforts primarily on geographies in the U.S. that have existing, active ZULRESSO
treating sites; the continued availability of healthcare settings in those geographies to administer ZULRESSO and the ability and
willingness of such healthcare settings to make sufficient capacity available; the level of reimbursement for both ZULRESSO and
the infusion in the healthcare setting both by commercial and government payors, and the nature of limitations on coverage and
reimbursement; the number of healthcare professionals willing to prescribe ZULRESSO and women with PPD who agree to be
treated with ZULRESSO; and the scope, duration and timing of the impact of the COVID-19 pandemic;

the timing and amount of costs associated with our commercialization of ZULRESSO;

the initiation, progress, timing, costs, and results of ongoing, planned and future non-clinical studies and clinical trials for
zuranolone and our other existing and future product candidates; the number and length of clinical trials required by regulatory
authorities to support regulatory approval; and the costs of preparing regulatory filings;

the length, severity and costs of disruptions, if any, associated with the COVID-19 pandemic on initiation and conduct of our
clinical trials;

98

 
 
 
 
 
 
 
 
•

•

•

•

•

•

•

the ability of zuranolone, SAGE-324, SAGE-718 and our other clinical-stage product candidates to progress through clinical
development successfully; the timing, scope and outcome of regulatory filings, reviews and approvals of such product candidates,
if we are successful in our development efforts; the scope and cost of any clinical trials or other commitments required post-
approval for any approved products resulting from such development efforts, if successful; and the level, timing and amount of
costs associated with permitted prelaunch activities and preparing for a potential future commercial launch of any such product
candidate that is successfully developed and approved;

the amounts we are entitled to receive, if any, from Biogen and Shionogi under our collaborations for cost-sharing, development,
regulatory, and sales milestones, and royalty payments;

the size of the PPD market and the portion of the population for which ZULRESSO may be prescribed; the size of the markets for
which zuranolone and our other product candidates may be approved in the future, if successfully developed; the portion of the
population in the approved indications for which our future products are actually prescribed; the rate and degree of market
acceptance for our products, and the pricing, availability and level of reimbursement for our products;

the number and characteristics of the product candidates we pursue in development and the nature and scope of our discovery and
development programs;

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

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

our ability to establish any future collaboration arrangements on favorable terms, if at all.

Until such time, if ever, as we can generate substantial product revenue and achieve profitability, we expect to also finance our cash

needs through a combination of equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other sources
of funding. Even if we believe we have sufficient funds for our current or future operating plans, we may seek additional capital if market
conditions are favorable or in light of other strategic considerations. To the extent that we raise additional capital through the sale of equity or
convertible debt securities, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation
or other preferences that adversely affect the rights of our common stockholders. Debt financing, if available, may involve agreements that
include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or
declaring dividends and may require the issuance of warrants, which could potentially dilute the ownership interest of our stockholders. If we
raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish
valuable rights to our technologies, future revenue streams or research programs or to grant licenses on terms that may not be favorable to us.
Raising funds in the current economic environment may present challenges. The COVID-19 pandemic initially caused major volatility in the
stock market and has caused a significant global economic downturn.  If the economic downturn caused by the pandemic continues for an
extended period or surges in the number of cases of COVID-19 continue or worsen in the future, or if our business prospects are impaired or
the capital markets disrupted for other reasons, additional capital may not be available to us on acceptable terms, or at all. If we are unable to
raise additional funds through equity or debt financings or other means when needed, we may be required to delay, limit, reduce or terminate
our product development or future commercialization efforts or grant rights to develop and market products or product candidates that we
would otherwise prefer to develop and market ourselves.

Amounts related to contingent milestone payments are not considered contractual obligations as they are contingent on the successful

achievement of certain milestones. These contingent milestones may not be achieved. We have not included any of these amounts in the table
as we cannot estimate or predict when, or if, these amounts will become due. We do not include amounts related to milestones for indications
that we are no longer pursuing.

(1) We lease office space in three multi-tenant buildings in Cambridge, Massachusetts, consisting, as of December 31, 2020, of 63,017

square feet in the first building under an operating lease that will expire on August 31, 2024, 40,419 square feet in the second building
under an operating lease that will expire on August 31, 2024 and 15,975 square feet in the third building under an operating lease that
will expire on February 29, 2024. We lease office space in a multi-tenant building in Raleigh, North Carolina, consisting of 15,525
square feet under an operating lease that will expire on November 30, 2024. In March 2019, we entered into the Eighth Amendment to
the lease for office space in the first building and thereby increased the amount of square feet of office space from 58,442 square feet to
63,017 square feet. The increase of 4,575 square feet began on June 1, 2019. The term for this additional space will expire on August 31,
2024. Effective February 1, 2021, we terminated the operating lease for the third building in Cambridge, Massachusetts. We may lease
additional space prior to the expiration of our leases to meet the needs of the business. The minimum lease payments in the table do not
include related common area maintenance costs or real estate taxes, because those costs are variable.

(2) We have acquired exclusive and non-exclusive rights to use, research, develop and offer for sale certain products and patents under

license agreements with Washington University, CyDex Pharmaceuticals, Inc. and two license agreements with the Regents. The license
agreements obligate us to make payments to the licensors for license fees, milestones, license maintenance fees and royalties. We are
obligated to make future remaining milestone payments under these agreements of up to an aggregate of $23.9 million upon achieving
certain milestones, related to clinical development, regulatory approvals and sales. During the year ended December 31, 2020, we
recorded expense and accrued expenses of $1.3 million for milestones under these license agreements.

(3) We enter into contracts in the normal course of business with CROs for clinical trials, non-clinical research studies and testing,

manufacturing and other services and products as part of general operations. These contracts generally provide for termination upon
notice, and we believe that our non-cancelable obligations under these agreements are not material.

Off-Balance Sheet Arrangements

We do not currently have, nor did we have during the periods presented, any off-balance sheet arrangements as defined by SEC rules.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We had cash, cash equivalents and marketable securities of approximately $2.1 billion as of December 31, 2020. The primary objectives
of our investment activities are to preserve principal, provide liquidity and maximize income without significantly increasing risk. Our primary
exposure to market risk relates to fluctuations in interest rates, which are affected by changes in the general level of U.S. interest rates. Given
the short-term nature of our cash, cash equivalents and marketable securities, we do not expect that a sudden change in market interest rates
would have a material impact on our financial condition and/or results of operations. We do not own any derivative financial instruments.

We contract with vendors in foreign countries and have subsidiaries in Europe. As such, we have exposure to adverse changes in

exchange rates of foreign currencies associated with our foreign transactions. We believe this exposure to be immaterial. We do not hedge
against this exposure to fluctuations in exchange rates.

We do not believe that our cash, cash equivalents and marketable securities have significant risk of default or illiquidity. While we

believe our cash, cash equivalents and marketable securities do not contain excessive risk, we cannot provide absolute assurance that in the
future our investments will not be subject to adverse changes in market value. In addition, we maintain significant amounts of cash, cash
equivalents and marketable securities at one or more financial institutions that are in excess of federally insured limits.

Inflation generally affects us by increasing our cost of labor and clinical trial costs. We do not believe that inflation had a material effect

on our results of operations during the year ended December 31, 2020.

statements is found in Item 15.

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

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of

1934, as amended, or the Securities Exchange Act of 1934) that are designed to ensure that information required to be disclosed in the reports
that we file or submit under the Securities Exchange Act of 1934 is (1) recorded, processed, summarized, and reported within the time periods
specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our President and Chief
Executive Officer, who is our principal executive officer, and our Chief Financial Officer, who is also our principal financial and accounting
officer, as appropriate, to allow timely decisions regarding required disclosure.

As of December 31, 2020, our management, with the participation of our principal executive officer and principal financial and
accounting officer, evaluated the effectiveness of our disclosure controls and procedures. Our management recognizes that any controls and
procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management
necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer
and principal financial and accounting officer have concluded, based upon the evaluation described above, that, as of December 31, 2020, our
disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule

13a-15(f) under the Securities Exchange Act of 1934). Our internal control over financial reporting is a process designed under the supervision
of our principal executive officer and principal financial officer to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of our financial statements for external purposes in accordance with generally accepted accounting principles. Management
evaluated the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (the 2013 Framework). Management, under
the supervision and with the participation of the principal executive officer and principal financial officer, assessed the effectiveness of our
internal control over financial reporting as of December 31, 2020 and concluded that it was effective based on those criteria.

The effectiveness of our internal control over financial reporting as of December 31, 2020 has been audited by PricewaterhouseCoopers

LLP, an independent registered public accounting firm, as stated in their report, which is included herein.

Changes in Internal Control over Financial Reporting

There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities

Exchange Act of 1934) that occurred during the quarter ended December 31, 2020 that have materially affected, or are reasonably likely to
materially affect, our internal control over financial reporting.

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

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Sage Therapeutics, Inc. and its subsidiaries (the “Company”) as of December 31, 2020 and
2019, and the related consolidated statements of operations and comprehensive income (loss), of changes in stockholders’ equity and of cash flows for each
of the three years in the period ended December 31, 2020, including the related notes (collectively referred to as the “consolidated financial statements”). We
also have audited the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control -
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of
December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in
conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material
respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework
(2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinions

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

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

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis,
evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used
and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing
such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

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

F-1

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

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

Critical Audit Matters

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

Accrued Research and Development Costs

As described in Notes 2 and 4 to the consolidated financial statements, the Company has entered into various research and development contracts with
research institutions and other companies. When billing terms under these contracts do not coincide with the timing of when the work is performed,
management is required to make estimates of outstanding obligations to those third parties as of the end of the reporting period. Within accrued expenses,
total accrued research and development costs amounted to $34.4 million as of December 31, 2020, which include accruals for these estimated ongoing
research and development costs.  Any accrual estimates are based on a number of factors, including management’s knowledge of the progress towards
completion of the research and development activities, invoicing to date under the contracts, communication from the research institution or other companies
of any actual costs incurred during the period that have not yet been invoiced, and the costs included in the contracts. Significant judgments and estimates are
made in determining the accrued balances at the end of any reporting period.

The principal considerations for our determination that performing procedures relating to accrued research and development costs is a critical audit matter are
(i) the significant judgment by management in determining the accrued costs and (ii) a high degree of auditor judgment, subjectivity and effort in performing
procedures and evaluating audit evidence for these accrued costs and the factors related to progress towards completion of the research and development
activities, invoicing to date under the contracts, and communication from the research institution or other companies of any actual costs incurred during the
period that have not yet been invoiced.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated
financial statements. These procedures included testing the effectiveness of controls relating to accrued research and development costs, including controls
over the review of contracts, accumulating information on actual costs incurred during the period, and assessment of progress towards completion of the
research and development activities. These procedures also included, among others, (i) testing management’s process for estimating accrued research and
development costs; (ii) evaluating the appropriateness of the method used by management to develop the estimates; (iii) evaluating the reasonableness of the
factors used in determining the estimates related to progress towards completion of specific research and development activities and the associated cost
incurred for services the Company has not yet been invoiced or otherwise notified of the actual cost at period end; and (iv) testing the completeness and
accuracy of the underlying data including total costs included within executed contracts and actual billed expenses under these contracts.

SAGE THERAPEUTICS, INC. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

1.

Nature of the Business

Sage Therapeutics, Inc. (“Sage” or the “Company”) is a biopharmaceutical company committed to developing and commercializing

novel medicines with the potential to transform the lives of people with debilitating disorders of the brain.  

The Company’s first product, ZULRESSO® (brexanolone) CIV injection, is approved in the U.S. as a treatment for postpartum
depression (“PPD”) in adults. The Company launched ZULRESSO commercially in the U.S. in June 2019. The Company has a portfolio of
other product candidates with a current focus on modulating two critical central nervous system (“CNS”) receptor systems, GABA and
NMDA. The GABA receptor family, which is recognized as the major inhibitory neurotransmitter in the CNS, mediates downstream
neurologic and bodily function via activation of GABAA receptors.  The NMDA-type receptors of the glutamate receptor system are a major
excitatory receptor system in the CNS.  Dysfunction in these systems is implicated in a broad range of CNS disorders.  The Company is
currently targeting diseases and disorders of the brain with three key focus areas: depression, neurology and neuropsychiatry.

The Company was incorporated under the laws of the State of Delaware on April 16, 2010, and commenced operations on January 19,

2011 as Sterogen Biopharma, Inc. On September 13, 2011, the Company changed its name to Sage Therapeutics, Inc.

The Company is subject to risks and uncertainties common to companies in the biotechnology and pharmaceutical industries, including,

but not limited to, the risks associated with developing product candidates at each stage of non-clinical and clinical development; the
challenges associated with gaining regulatory approval of such product candidates; the risks associated with the marketing and sale of
pharmaceutical products; the potential for development by third parties of new technological innovations that may compete with the
Company’s products and product candidates; the dependence on key personnel; the challenges of protecting proprietary technology; the need to
comply with government regulations; the high costs of drug development; the impact of the COVID-19 pandemic on its operations and
financial condition; and the uncertainty of being able to secure additional capital when needed to fund operations.

Under Accounting Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40),

the Company has the responsibility to evaluate whether conditions and/or events raise substantial doubt about its ability to meet its future
financial obligations as they become due within one year after the date that the financial statements are issued. The Company has incurred
losses and negative cash flows from operations since its inception, except for net income of $606.1 million for the year ended December 31,
2020, because of revenue recognized under a license and collaboration agreement with Biogen MA Inc. (“BIMA”) and Biogen International
GmbH (collectively with BIMA, “Biogen”). As of December 31, 2020, the Company had an accumulated deficit of $1.0 billion. From its
inception through December 31, 2020, the Company has received aggregate net proceeds of $2.8 billion from the sales of redeemable
convertible preferred stock prior to its initial public offering, the issuance of convertible notes, and the sales of common stock in its initial
public offering (“IPO”) in July 2014, follow-on public offerings and the sale of stock to Biogen. The Company also received $1.0 billion in
upfront payments under its collaborations with Biogen and Shionogi & Co., Ltd. (“Shionogi”). Until such time, if ever, as the Company can
generate substantial product revenue and achieve profitability, the Company expects to finance its cash needs through a combination of equity
offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other sources of funding.  If the Company is unable to
raise additional funds through equity or debt financings or other sources of funding when needed, the Company may be required to delay, limit,
reduce or terminate product development or future commercialization efforts or grant rights to develop and market products or product candidates
that the Company would otherwise prefer to develop and market itself.

The Company expects that, based on its current operating plans, the Company’s existing cash, cash equivalents and marketable securities

will be sufficient to fund its currently planned operations for at least the next 12 months from the filing date of this Annual Report. At some
point after that time, the Company anticipates it will require additional financing to fund its future operations. Even if the Company believes it
has sufficient funds for its current or future

F-7

 
 
 
operating plans, the Company may seek to raise additional capital if market conditions are favorable or in light of other strategic
considerations.

COVID-19

The ongoing COVID-19 pandemic has caused and may continue to cause major disruptions to businesses and economies worldwide.

The rapid spread of COVID-19 in the U.S. has resulted in a significant reduction in patient demand for ZULRESSO and in the number of sites
available to administer ZULRESSO. This has had a negative impact on the Company’s revenue from sales of ZULRESSO.  While there have
been no material disruptions to date, any prolonged material disruptions to the work of the Company’s employees, suppliers, contract
manufacturers, or vendors as a result of the COVID-19 pandemic could negatively impact the Company’s activities, availability of supplies, or
operating results. Similarly, while to date the Company has not experienced significant impacts to the Company’s development activities, any
material disruption to the Company’s development activities as a result of the COVID-19  pandemic may cause delays, increase the Company’s
costs and impact the Company’s operating results. In addition, the COVID-19 pandemic initially caused major volatility in capital markets and
has caused a significant global economic downturn, and the Company’s ability to access the capital markets in the future could
be negatively impacted if the adverse effects of the pandemic continue.

Summary of Significant Accounting Policies

The following is a summary of significant accounting policies followed in the preparation of these consolidated financial statements.

Basis of Presentation

The accompanying consolidated financial statements include those of the Company and its subsidiaries after elimination of all
intercompany accounts and transactions. The accompanying consolidated financial statements have been prepared in conformity with
accounting principles generally accepted in the U.S. (“GAAP”).

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions

that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during the reporting period. The full extent to which the COVID-19
pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition, including sales, expenses,
reserves and allowances, manufacturing, clinical trials, research and development costs and employee-related amounts, will depend on future
developments that are highly uncertain, including developments related to the scope and duration of the pandemic; the duration and severity of
precautionary measures taken to curb the spread of COVID-19, the length, location and frequency of surges or waves of COVID-19 cases and
the timing and success of the roll-out of vaccines for COVID-19, and any return to normal business operations across the U.S. The Company
has made estimates of the impact of the COVID-19 pandemic within its consolidated financial statements, and there may be changes to those
estimates in future periods. Actual results could differ from those estimates.

Cash Equivalents

The Company considers all highly liquid investments with an original maturity of 90 days or less at the date of purchase to be cash

equivalents. As of December 31, 2020, cash equivalents were comprised of commercial paper, money market funds and U.S. treasury
securities. As of December 31, 2019, cash equivalents were comprised of commercial paper and money market funds.

F-8

 
 
Marketable securities

Marketable securities consist of investments with original maturities greater than 90 days. The Company has classified its

investments with maturities beyond one year as short-term, based on their highly liquid nature and because such marketable securities represent
the investment of cash that is available for current operations. The Company considers its investment portfolio of marketable securities to be
available-for-sale. Accordingly, these investments are recorded at fair value, which is based on quoted market prices. Unrealized gains and
losses are reported as the accumulated other comprehensive items in stockholders’ equity. When the fair value is below the amortized cost of
the asset, an estimate of expected credit losses is made. The credit-related impairment amount is recognized in net income; the remaining
impairment amount and unrealized gains are reported as a component of accumulated other comprehensive income (loss) in stockholders’
equity. Credit losses are recognized through the use of an allowance for credit losses account and subsequent improvements in expected credit
losses are recognized as a reversal of an amount in the allowance account. If the Company has the intent to sell the security or it is more likely
than not that the Company will be required to sell the security prior to recovery of its amortized cost basis, then the allowance for the credit
loss is written-off and the excess of the amortized cost basis of the asset over its fair value is recorded in net income. Regardless of the
Company’s intent to sell a security, it performs additional analysis on all securities with unrealized losses to evaluate losses associated with the
creditworthiness of the security. Credit losses are identified where the Company does not expect to receive cash flows sufficient to recover the
amortized cost basis of a security.

Accounts Receivable

The Company’s trade accounts receivable consist of amounts due from specialty distributors, specialty pharmacies, and medically-
supervised healthcare settings that have been certified under a Risk Evaluation and Mitigation Strategy (“REMS”) program in the U.S. related
to sales of ZULRESSO and have standard payment terms that generally require payment within 30 to 90 days from the invoice date. The
Company monitors the financial performance and creditworthiness of customers so that it can properly assess and respond to changes in their
credit profile. The Company makes judgments as to its ability to collect outstanding receivables and provides an allowance for receivables
when appropriate. Trade accounts receivable are included in prepaid expenses and other current assets on the consolidated balance sheets. As
of December 31, 2020, the Company has not provided any allowance for bad debts against the trade accounts receivable, and the amount of
trade accounts receivable was not significant.

Inventory

Inventory is stated at the lower of cost or estimated net realizable value with cost determined on a first-in, first-out basis. Inventory costs
include raw materials, third-party contract manufacturing, third-party packaging services, and freight. Raw and intermediate materials that may
be utilized for either research and development or commercial purposes are identical and, as a result, are both classified as inventory. Amounts
in inventory associated with research and development are charged to research and development expense when the product enters the research
and development process and can no longer be used for commercial purposes and, therefore, does not have an “alternative future use” as
defined in authoritative guidance. The Company performs an assessment of the recoverability of capitalized inventory during each reporting
period and writes down any excess and obsolete inventory to its estimated net realizable value in the period it is identified. If they occur, such
impairment charges are recorded as a component of cost of goods sold in the consolidated statements of operations and comprehensive income
(loss). Inventory is included in prepaid expenses and other current assets on the consolidated balance sheets and the amount was not significant
as of December 31, 2020.

Prior to the initial date regulatory approval is received, costs related to the production of inventory are recorded as research and
development expense on the Company’s consolidated statements of operations and comprehensive income (loss) in the period incurred. The
Company received FDA approval for ZULRESSO on March 19, 2019 and subsequently began capitalizing costs related to inventory
manufacturing.

Property and Equipment

Property and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line method. Upon

retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed

F-9

 
 
 
from the accounts and any resulting gain or loss is credited or charged to income. Repairs and maintenance costs are expensed as incurred.

Intangible assets

The Company had no intangible assets as of December 31, 2018. The Company received FDA approval for ZULRESSO on March 19,

2019, and as a result, the Company was required to pay to CyDex Pharmaceuticals, Inc. (“CyDex”) and The Regents of the University of
California (the “Regents”) milestone payments of $3.0 million and $0.5 million, respectively. At March 31, 2019, the amount of these
milestones was capitalized as an intangible asset, and it is being amortized to cost of goods sold over the expected useful life of the asset.

Leases

The Company determines if an arrangement is a lease at contract inception. Operating lease assets represent the Company’s right to use
an underlying asset for the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from
the lease. Operating lease assets and liabilities are recognized at the commencement date of the lease based upon the present value of lease
payments over the lease term. When determining the lease term, the Company includes options to extend or terminate the lease when it is
reasonably certain that the Company will exercise that option. The Company uses the implicit interest rate when readily determinable and uses
the Company’s incremental borrowing rate when the implicit rate is not readily determinable based upon the information available at the
commencement date in determining the present value of the lease payments.

The lease payments used to determine the Company’s operating lease assets may include lease incentives, stated rent increases and
escalation clauses linked to rates of inflation, when determinable, and are recognized in the Company’s operating lease assets in the Company’s
consolidated balance sheets. In addition, the Company’s contracts contain lease and non-lease components. The Company combines lease and
non-lease components, which are accounted for together as lease components.

The Company’s operating leases are reflected in the right-of-use operating asset; operating lease liability, current portion; and operating
lease liability, net of current portion in the Company’s consolidated balance sheets. Lease expense for minimum lease payments is recognized
on a straight-line basis over the lease term. Short-term leases, defined as leases that have a lease term of 12 months or less at the
commencement date, are excluded from this treatment and are recognized on a straight-line basis over the term of the lease.

Variable lease payments are the amounts owed by the Company to a lessor that are not fixed, such as reimbursement for common area
maintenance and utilities costs for facility leases and maintenance and tolls for leased vehicles. Variable lease payments are expensed when
incurred.

Impairment of Long-Lived Assets

Long-lived assets consist of property and equipment. Long-lived assets to be held and used are tested for recoverability whenever events

or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company
considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations,
significant negative industry or economic trends, and significant changes or planned changes in the use of the assets. If an impairment review is
performed to evaluate a long-lived asset group for recoverability, the Company compares forecasts of undiscounted cash flows expected to
result from the use and eventual disposition of the long-lived asset group to its carrying value. The impairment loss would be based on the
excess of the carrying value of the impaired asset over its fair value, determined based on discounted cash flows. To date, the Company has not
recorded any impairment losses on long-lived assets.

Cost of Goods Sold

Cost of goods sold includes direct and indirect costs related to the manufacturing and distribution of ZULRESSO, including third-party

manufacturing costs, packaging services, freight, third-party royalties payable on the Company’s net

F-10

 
 
product revenues and amortization of intangible assets associated with ZULRESSO. Cost of goods sold may also include period costs related to
certain inventory manufacturing services, inventory adjustment charges, as well as manufacturing variances. In connection with the FDA
approval of ZULRESSO on March 19, 2019, the Company subsequently began capitalizing inventory manufactured or purchased after this
date. As a result, certain manufacturing costs associated with product shipments of ZULRESSO were expensed prior to FDA approval and,
therefore, are not included in cost of goods sold during the years ended December 31, 2020 and 2019.

Research and Development Costs and Accruals

Research and development expenses are comprised of costs incurred in performing research and development activities, including
salaries and benefits, overhead costs, depreciation, contract services and other related costs. Research and development costs are expensed to
operations as the related obligation is incurred.

The Company has entered into various research and development contracts with research institutions and other companies both inside

and outside of the U.S. These agreements are generally cancelable, and related costs are recorded as research and development expenses as
incurred. The Company records accruals for estimated ongoing research and development costs. When billing terms under these contracts do
not coincide with the timing of when the work is performed, the Company is required to make estimates of outstanding obligations to those
third parties as of the end of the reporting period.  Any accrual estimates are based on a number of factors, including the Company’s knowledge
of the progress towards completion of the research and development activities, invoicing to date under the contracts, communication from the
research institution or other companies of any actual costs incurred during the period that have not yet been invoiced, and the costs included in
the contracts. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual
results could differ from the estimates made by the Company. The historical accrual estimates made by the Company have not been materially
different from the actual costs.

Patent Costs

The Company expenses patent costs as incurred and classifies such costs as selling, general and administrative expenses in the

accompanying consolidated statements of operations and comprehensive income (loss).

Stock-Based Compensation

The Company recognizes compensation expense for stock-based awards, including grants of stock options and restricted stock units,
made to employees and non-employee directors based on the estimated fair value on the date of grant, over the requisite service period. The
Company recognizes stock-based compensation expense for only the portion of awards that are expected to vest.

Effective January 1, 2019, the Company recognizes compensation expense for stock-based awards, including grants of stock options and

restricted stock units, made to non-employee consultants based on the estimated fair value on the date of grant, over the requisite service
period. Through December 31, 2018, the Company recognized compensation expense for stock-based awards granted to non-employee
consultants based on the fair value of the awards on each date on which the awards vest. Compensation expense was recognized over the
vesting period, provided that services were rendered by such non-employee consultants during that time. At the end of each financial reporting
period, the fair value of unvested options was re-measured using the then-current fair value of the common stock of the Company and updated
assumptions using the Black-Scholes option-pricing model.

For awards that vest upon achievement of a performance condition, the Company recognizes compensation expense when achievement

of the performance condition is met or during the period from which meeting the condition is deemed probable until the expected date of
meeting the performance condition.

The fair value of each option grant is estimated using the Black-Scholes option-pricing model. For the years ended December 31, 2019

and 2018, the Company estimated its expected volatility using a weighted average of the historical volatility of publicly-traded peer companies
and the volatility of its common stock. Effective January 1, 2020, the

F-11

 
Company began using the historical volatility of only its common stock, as there is adequate historical data for the duration of the expected
term.

The expected term of the options granted to employees and non-employee directors by the Company has been determined utilizing the
“simplified” method for awards that qualify as “plain-vanilla” options. Through December 31, 2018, the expected term of the options granted
to non-employee consultants was determined based on the contractual term of the options, and since January 1, 2019, the “simplified” method
has been used. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award
for time periods approximately equal to the expected term of the award. The expected dividend yield is based on the fact that the Company has
never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future.

The Company also applies a forfeiture rate in order to calculate stock-based compensation expense. Expected forfeitures are based on
the historical experience of the Company and management’s expectations of future forfeitures. To the extent actual forfeitures differ from the
estimates, the difference is recorded as a cumulative adjustment in the period in which the estimates are revised.

Treasury Stock

The Company records treasury stock at cost. Treasury stock consists of shares received from an employee as consideration for exercises

of stock options.

Basic and Diluted Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of shares of common
stock that were outstanding during the period. Diluted net income (loss) per share is computed by adjusting the weighted average number of
shares of common stock that were outstanding during the period for the dilutive effect of common stock equivalents outstanding for the period
by using the treasury stock method.

For periods in which the Company has reported net losses, diluted net loss per share is the same as basic net loss per share, because
dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss for the years ended
December 31, 2019 and 2018.

Risks and Uncertainties

The product candidates developed by the Company require approvals from the U.S. Food and Drug Administration or foreign regulatory

agencies prior to commercial sales. There can be no assurance that the current and future product candidates of the Company will receive the
necessary approvals. If the Company fails to successfully complete clinical development and generate results sufficient to file for regulatory
approval or is denied approval or approval is delayed, it may have a material adverse impact on the Company’s business and its financial
statements.

Concentration of Credit Risk and of Significant Suppliers

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents and

marketable securities. The Company maintains accounts for all cash and cash equivalents at accredited financial institutions, in amounts that
exceed federally insured limits. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated
with commercial banking relationships.

The Company is dependent on third-party manufacturers to supply products for research and development activities in its programs. The

Company relies and expects to continue to rely on a small number of manufacturers to supply it with its requirements for the active
pharmaceutical ingredients and formulated drugs related to these programs. These programs could be adversely affected by a significant
interruption in the supply of active pharmaceutical ingredients and formulated drugs.

Income Taxes

The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are

recognized for the estimated future tax consequences attributable to differences between financial statement carrying amounts of existing assets
and liabilities and their respective tax bases. Deferred tax assets and

F-12

 
liabilities are measured using enacted rates in effect for the year in which these temporary differences are expected to be recovered or settled.
Valuation allowances are provided if, based on 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 Accounting Standards Codification (“ASC”)

Topic 740, “Income Taxes” (“Topic 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
accrues for potential interest and penalties related to unrecognized tax benefits in income tax expense.

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. Financial assets and liabilities carried at fair value are classified and disclosed in one of the following
three categories:

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

Level 2   —  Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are

not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of
the assets or liabilities.

Level 3   —  Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or

liabilities.

The Company’s cash equivalents and marketable securities at December 31, 2020 and 2019 were carried at fair value, determined

according to the fair value hierarchy; see Note 3, Fair Value Measurements.

The carrying amounts reflected in the consolidated balance sheets for accounts payable and accrued expenses approximate their fair

values due to their short-term maturities at December 31, 2020 and 2019, respectively.

Segment Data

The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions.

The singular focus of the Company is developing and commercializing novel medicines with the potential to transform the lives of people with
debilitating disorders of the brain.

Comprehensive Income (Loss)

Comprehensive income (loss) includes net income (loss) and other changes in stockholders’ equity that result from transactions and

economic events other than those with stockholders.

Revenue Recognition

The Company generates revenue from the sale of ZULRESSO, which was approved by the FDA in March 2019 and the Company

subsequently began selling in June 2019, and from collaboration and supply agreements with the Company’s collaborators. To date, revenue
from collaboration agreements has come from initial, upfront payments allocated to licenses of intellectual property delivered to the
Company’s collaborators and from the supply of material for clinical trials under a supply agreement.

Under ASC Topic 606, “Revenue from Contracts with Customers” (“Topic 606”), an entity recognizes revenue when its customer

obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for
those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the
entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract;
(iii) determine the transaction price,

F-13

 
 
 
 
 
 
   
 
 
 
   
 
 
including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize
revenue when (or as) the entity satisfies a performance obligation. Arrangements that include rights to additional goods or services that are
exercisable at a customer’s discretion are generally considered options. The Company assesses if these options provide a material right to the
customer and if so, they are considered performance obligations. The exercise of a material right may be accounted for as a contract
modification or as a continuation of the contract for accounting purposes.

For contracts determined to be within the scope of Topic 606, the Company assesses whether the goods or services promised within each

contract are distinct to identify those that are performance obligations. This assessment involves subjective determinations and requires
management to make judgments about the individual promised goods or services and whether such are separable from the other aspects of the
contractual relationship. Promised goods and services are considered distinct provided that: (i) the customer can benefit from the good or
service either on its own or together with other resources that are readily available to the customer and (ii) the entity’s promise to transfer the
good or service to the customer is separately identifiable from other promises in the contract.

The Company allocates the transaction price (the amount of consideration it expects to be entitled to from a customer in exchange for the
promised goods or services) to each performance obligation and recognizes the associated revenue when (or as) each performance obligation is
satisfied. The Company’s estimate of the transaction price for each contract includes all variable consideration to which the Company expects
to be entitled.

Collaboration and license revenue

In assessing whether a promised good or service is distinct in the evaluation of a collaboration or license arrangement subject to Topic

606, the Company considers factors such as the research, manufacturing and commercialization capabilities of the collaboration partner and the
availability of the associated expertise in the general marketplace. The Company also considers the intended benefit of the contract in assessing
whether a promised good or service is separately identifiable from other promises in the contract. If a promised good or service is not distinct,
the Company is required to combine that good or service with other promised goods or services until it identifies a bundle of goods or services
that is distinct.

The transaction price is then determined and allocated to the identified performance obligations in proportion to their standalone selling
prices (“SSP”) on a relative SSP basis. SSP is determined at contract inception and is not updated to reflect changes between contract inception
and when the performance obligations are satisfied. Determining the SSP for performance obligations requires significant judgment. In
developing the SSP for a performance obligation, the Company considers applicable market conditions and relevant entity-specific factors,
including factors that were contemplated in negotiating the agreement with the customer and estimated costs.  In certain circumstances, the
Company may apply the residual method to determine the SSP of a good or service if the standalone selling price is considered highly variable
or uncertain. The Company validates the SSP for performance obligations by evaluating whether changes in the key assumptions used to
determine the SSP will have a significant effect on the allocation of arrangement consideration between multiple performance obligations.

If the consideration promised in a contract includes a variable amount, the Company estimates the amount of consideration to which it

will be entitled in exchange for transferring the promised goods or services to a customer. The Company determines the amount of variable
consideration by using the expected value method or the most likely amount method. The Company includes the unconstrained amount of
estimated variable consideration in the transaction price. The amount included in the transaction price is constrained to the amount for which it
is probable that a significant reversal of cumulative revenue recognized will not occur. At the end of each subsequent reporting period, the
Company re-evaluates the estimated variable consideration included in the transaction price and any related constraint, and if necessary, adjusts
its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis in the period of adjustment.

If an arrangement includes development and regulatory milestone payments, the Company evaluates whether the milestones are
considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If
it is probable that a significant revenue reversal would not occur, the associated

F-14

 
milestone value is included in the transaction price. Milestone payments that are not within the Company’s control or the licensee’s control,
such as regulatory approvals, are generally not considered probable of being achieved until those approvals are received.

In determining the transaction price, the Company adjusts consideration for the effects of the time value of money if the timing of

payments provides the Company with a significant benefit of financing. The Company does not assess whether a contract has a significant
financing component if the expectation at contract inception is such that the period between payment by the licensees and the transfer of the
promised goods or services to the licensees will be one year or less. The Company assessed its arrangements with Shionogi and Biogen and
concluded that a significant financing component does not exist for either arrangement. For arrangements with licenses of intellectual property
that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant
item to which the royalties relate, the Company recognizes royalty revenue and sales-based milestones at the later of (i) when the related sales
occur, or (ii) when the performance obligation to which the royalty has been allocated has been satisfied.

The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation

when (or as) each performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or
input method. Revenue from the Company’s collaboration agreement with Shionogi has come from initial, upfront consideration upon
execution of the agreement and for the supply of drug product for Shionogi’s clinical trials. Revenue from the Company’s collaboration
agreement with Biogen has come from initial, upfront consideration related to the execution of the license and collaboration agreement. For
additional information, refer to Note 6, Collaboration Agreements.

Product revenue

The Company recognizes product revenues, net of variable consideration related to certain allowances and accruals that are determined
using the expected value method, in its consolidated financial statements at the point in time when control transfers to the customer, which is
typically when the product has been delivered to the customer’s location. The amount included in the transaction price is constrained to the
amount for which it is probable that a significant reversal of cumulative revenue recognized will not occur. The Company’s only performance
obligation identified for ZULRESSO is to deliver the product to the location specified by the customer’s order. The Company records shipping
and handling costs associated with delivery of product to its customers within selling, general and administrative expenses on its consolidated
statements of operations and comprehensive income (loss). The Company expenses incremental costs of obtaining a contract as incurred if the
expected amortization period of the asset would be less than one year. If the Company were to incur incremental costs with an amortization
period greater than a year, such costs would be capitalized as contract assets, as they are expected to be recovered, and would be expensed by
amortizing on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. The
Company did not have any contract assets (unbilled receivables) at December 31, 2020, as customer invoicing generally occurs before or at the
time of revenue recognition. The Company did not have any contract liabilities at December 31, 2020, as the Company did not

F-15

 
 
 
receive any payments in advance of satisfying its performance obligations to its customers. Amounts billed or invoiced are included in prepaid
expenses and other current assets on the consolidated balance sheets.

The Company records reserves, based on contractual terms, for the following components of variable consideration related to product

sold during the reporting period, as well as its estimate of product that remains in the distribution channel inventory of its customers at the end
of the reporting period. On a quarterly basis, the Company updates its estimates and records any necessary material adjustments in the period
they are identified.

Chargebacks: The Company estimates chargebacks from its customers who directly purchase the product from the Company for
discounts resulting from contractual commitments to sell products to eligible healthcare settings at prices lower than the list prices
charged to its customers. Customers charge the Company for the difference between what they pay to the Company for the product
and the selling price to the eligible healthcare settings. Reserves for chargebacks consist of credits that the Company expects to issue
for units that remain in the distribution channel inventories at the end of each reporting period that the Company expects will be sold
to eligible healthcare settings, and chargebacks that customers have claimed, but for which the Company has not yet issued a credit.

Government Rebates: The Company is subject to discount obligations under government programs, including Medicaid. The
Company records reserves for rebates in the same period the related product revenue is recognized, resulting in a reduction of
ZULRESSO product revenues and a current liability that is included in accrued expenses on its consolidated balance sheets.  The
Company’s liability for these rebates consists of invoices received for claims from prior quarters that have not been paid or for which
an invoice has not yet been received, estimates of claims for the current quarter, and estimates of future claims that will be made for
product that has been recognized as revenue, but which remains in the distribution channel at the end of each reporting period.

Trade Discounts and Allowances: The Company generally provides customary invoice discounts on ZULRESSO sales to its
customers for prompt payment and the Company pays fees for sales order management, data, and distribution services. The Company
estimates its customers will earn these discounts and fees and deducts these discounts and fees in full from gross ZULRESSO
revenues and accounts receivable at the time the Company recognizes the related revenues.

Financial Assistance: The Company provides voluntary financial assistance programs to patients with commercial insurance that
have coverage and reside in states that allow financial assistance. The Company estimates the financial assistance amounts for
ZULRESSO and records any such amounts within accrued expenses on its consolidated balance sheets. The calculation of the accrual
for financial assistance is based on an estimate of claims and the cost per claim that the Company expects to receive using
demographics for patients who have registered and been approved for assistance. Any adjustments are recorded in the same period
the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability, which is
included as a component of accrued expenses on the consolidated balance sheets.

Product Returns: Consistent with industry practice, the Company offers product return rights to direct customers for damaged,
defective or expiring product, provided it is within a specified period around the product expiration date as set forth in the Company’s
return goods policy. The Company estimates the amount of its product sales that may be returned by its customers and records this
estimate as a reduction of revenue in the period the related product revenue is recognized, as well as a reserve within accrued
expenses on the consolidated balance sheets. The Company has experienced no product returns to date. The Company will update its
estimated refund liability, on at least a quarterly basis, based on actual shipments of ZULRESSO subject to contractual return rights,
changes in expectations about the amount of estimated refunds or actual returns.

Collaborative arrangements

F-16

 
 
 
 
 
 
 
 
 
 
The Company analyzes its collaboration arrangements to assess whether such arrangements involve joint operating activities performed

by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of
such activities and therefore within the scope of ASC Topic 808, Collaborative Arrangements (“Topic 808”). This assessment is performed
throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. For collaboration arrangements
within the scope of Topic 808 that contain multiple elements, the Company first determines which elements of the collaboration are deemed to
be within the scope of Topic 808 and which elements of the collaboration are more reflective of a vendor-customer relationship and therefore
within the scope of Topic 606. For elements of collaboration arrangements that are accounted for pursuant to Topic 808, an appropriate
recognition method is determined and applied consistently, either by analogy to authoritative accounting literature or by applying a reasonable
and rational policy election. For those elements of the arrangement that are accounted for pursuant to Topic 606, the Company applies the five-
step model described above.

Recently Issued Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842), which replaced

the existing guidance in ASC Topic 840, “Leases” (“Topic 840”). The FASB subsequently issued the following amendments to ASU No. 2016-
02 that have the same effective date and transition date: ASU No. 2018-01, Leases (Topic 842): Land Easement Practical Expedient for
Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; ASU No. 2018-11, Leases (Topic 842): Targeted
Improvements; ASU No. 2018-20, Narrow-Scope Improvement for Lessors; and ASU No. 2019-01, Leases (Topic 842): Codification
Improvements. The Company adopted these amendments with ASU No. 2016-02 effective January 1, 2019 (ASU No. 2016-02 as amended,
“ASC 842”). The ASC 842 standard generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-
use assets on the consolidated balance sheets and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash
flows arising from leasing arrangements. The Company adopted ASC 842 using the modified retrospective approach with an effective date of
January 1, 2019 for leases that existed on that date. Prior period results continue to be presented under Topic 840 based on the accounting
standards originally in effect for such periods. Presentation of leases within the consolidated statements of operations and comprehensive
income (loss) and consolidated statements of cash flows is generally consistent with the former lease accounting guidance. The Company
elected the package of practical expedients permitted under the transition guidance and as such, the adoption of this ASU did not change the
classification of any of the Company’s leases. The Company elected to combine lease and non-lease components, elected not to record leases
with an initial term of 12 months or less on the consolidated balance sheets and will recognize the associated lease payments in the
consolidated statements of operations and comprehensive income (loss) on a straight-line basis over the lease term.  On the adoption date,
$44.2 million was recognized as total lease liabilities, and $41.1 million was recognized as total right-of-use assets on the Company’s
consolidated balance sheet.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on
Financial Instruments. This standard amends the impairment model by requiring entities to use a forward-looking approach based on expected
losses to estimate credit losses for most financial assets and certain other instruments that are not measured at fair value through net income.
For available-for-sale debt securities, entities are required to recognize an allowance for credit losses rather than a reduction in carrying value
of the asset. Entities are no longer permitted to consider the length of time that fair value has been less than amortized cost when evaluating
when credit losses should be recognized. The Company adopted the standard on the required effective date of January 1, 2020, on a prospective
basis. This guidance did not have a significant impact on the Company’s consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the
Disclosure Requirements for Fair Value Measurement. This standard modifies certain disclosure requirements on fair value measurements. The
Company adopted the standard on the required effective date of January 1, 2020. This guidance did not have a significant impact on the
Company’s consolidated financial statements and related disclosures.

In November 2018, the FASB issued ASU No. 2018-18, Clarifying the Interaction between Topic 808 and Topic 606. This standard

clarifies that certain transactions between collaborative arrangement participants should be accounted

F-17

 
 
 
 
 
for as revenue under Topic 606 when the collaborative arrangement participant is a customer for a promised good or service that is distinct
within the collaborative arrangement. The guidance also precludes entities from presenting amounts related to transactions with a collaborative
arrangement participant that is not a customer as revenue, unless those transactions are directly related to third-party sales. The Company
adopted the standard on the required effective date of January 1, 2020. This guidance did not have a significant impact on the Company’s
consolidated financial statements and related disclosures.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This

standard enhances and simplifies various aspects of the income tax accounting guidance in Topic 740, including requirements related to hybrid
tax regimes, the tax basis step-up in goodwill obtained in a transaction that is not a business combination, separate financial statements of
entities not subject to tax, the intra-period tax allocation exception to the incremental approach, ownership changes in investments, changes
from a subsidiary to an equity method investment, interim-period accounting for enacted changes in tax law, and the year-to-date loss limitation
in interim-period tax accounting. This guidance will be effective for the Company for annual and interim periods beginning after December 31,
2020. The Company is currently in the process of evaluating the impact to its consolidated financial statements.

Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption

until a future date are not expected to have a material impact on the Company’s consolidated financial statements upon adoption.

Fair Value Measurements

The Company’s cash equivalents are classified within Level 1 and Level 2 of the fair value hierarchy.  The Company’s investments in

marketable securities are classified within Level 2 of the fair value hierarchy.

The fair values of the Company’s marketable securities are based on prices obtained from independent pricing sources.  Consistent with

the fair value hierarchy described in Note 2, Summary of Significant Accounting Policies, securities with validated quotes from pricing
services are reflected within Level 2, as they are primarily based on observable pricing for similar assets or other market observable
inputs.  Typical inputs used by these pricing services include, but are not limited to, reported trades, benchmark yields, issuer spreads, bids,
offers or estimates of cash flow, prepayment spreads and default rates.

Leases, Commitments and Contingencies

Operating Leases

The Company has leases for office space and certain equipment. All of the leases recorded on the consolidated balance sheets are
operating leases. The Company’s leases have remaining lease terms ranging from less than one year to nearly four years.  Some of the leases
include options to extend the leases for up to five years. These options were not included for the purpose of determining the right-of-use assets
and associated lease liabilities as the Company determined

that the renewal of these leases is not reasonably certain so only the original lease term was taken into consideration.  The leases do not include
any restrictions or covenants that had to be accounted for under the lease guidance.

As of January 1, 2018, the Company leased office space in two multi-tenant buildings in Cambridge, Massachusetts, consisting of
54,943 square feet in the first building under an operating lease that will expire on August 15, 2024 and 19,805 square feet in the second
building under an operating lease that will expire on February 28, 2022.

In April 2018, the Company entered into the First Amendment to the lease for office space in the second multi-tenant building and

thereby increased the amount of square feet of office space from 19,805 square feet to 40,419 square feet, an increase of 20,614 square feet,
consisting of (i) 13,481 square feet that began on August 1, 2018, and (ii) 7,133 square feet that began on October 1, 2018.  The term for this
additional space will expire on August 31, 2024.  Additionally, the term of the existing lease was extended from February 28, 2022 until
August 31, 2024.  

In May 2018, the Company entered into a lease for office space in a multi-tenant building in Raleigh, North Carolina.  The amount of

square feet of office space is 15,525 square feet and the lease period began on September 1, 2018.  The term for this space will expire on
November 30, 2024.

In October 2018, the Company entered into the Seventh Amendment to the lease for office space in the first building and thereby
increased the amount of square feet of office space from 54,943 square feet to 58,442 square feet. The increase of 3,499 square feet began on
December 1, 2018. The term for this additional space will expire on August 31, 2024. 

In December 2018, the Company entered into a lease for office space in a third multi-tenant building in Cambridge, Massachusetts. The

amount of square feet of office space is 15,975 square feet and the lease period began on March 1, 2019. The term for this lease was initially
scheduled to expire on February 29, 2024. Effective February 1, 2021, the Company terminated this lease.

F-21

 
In March 2019, the Company entered into the Eighth Amendment to the lease for office space in the first multi-tenant building and

thereby increased the amount of square feet of office space from 58,442 square feet to 63,017 square feet. The increase of 4,575 square feet
began on June 1, 2019.  The term for this additional space will expire on August 31, 2024.

From June 2018 to January 2019, the Company entered into leases for vehicles for field-based employees. These leases were determined
to be operating leases and a right-of-use operating asset in the amount of $5.3 million was recorded on the balance sheet upon implementation
of the new lease standard on January 1, 2019. The leases were for a term of three years and were to expire on various dates through January 31,
2022. During the year ended December 31, 2020, these leases were terminated as part of the April 2020 restructuring (see Note 13,
Restructuring), and the remaining asset of $2.3 million and the liabilities related to these leases were de-recognized upon termination of the
leases, and the restricted cash of $0.7 million related to these leases was returned to the Company by the lessor.

During the year ended December 31, 2019, other than the initial adoption of the lease standard that required right-of-use assets and lease

liabilities to be recorded, one right-of-use asset was recorded arising from new lease liabilities. In March 2019, the Company entered into the
Eighth Amendment to the lease for office space in the first building and thereby increased the amount of square feet of office space from
58,442 square feet to 63,017 square feet. The increase of 4,575 square feet began on June 1, 2019.  The term for this additional space will
expire on August 31, 2024.

During the year ended December 31, 2020, the one right-of-use asset was de-recognized. The leases for vehicles for field-based

employees were terminated as part of the April 2020 restructuring (see Note 13, Restructuring), and the remaining asset of $2.3 million and the
liabilities related to these leases were de-recognized upon termination of the leases.

License Agreements

CyDex License Agreement

In September 2015, the Company and CyDex, a wholly owned subsidiary of Ligand Pharmaceuticals, Inc., amended and restated their
existing commercial license agreement. Under the terms of the commercial license agreement as amended and restated, CyDex has granted to
the Company an exclusive license to CyDex’s Captisol drug formulation technology and related intellectual property for the manufacture of
pharmaceutical products incorporating brexanolone and the Company’s compound known as SAGE-689, and the development and
commercialization of the resulting products in the treatment, prevention or diagnosis of any disease or symptom in humans or animals other
than (i) the ocular treatment of any disease or condition with a formulation, including a hormone; (ii) topical ocular treatment of inflammatory
conditions; (iii) treatment and prophylaxis of fungal infections in humans; and (iv) any ocular treatment for retinal degeneration. The Company
is required to pay a royalty to CyDex on sales of brexanolone and will be required to pay a royalty on sales of SAGE-689, if such product
candidate is successfully developed in the future.  Royalty rates are in the low single digits based on levels of net sales. As of December 31,
2020, the Company has paid to CyDex $1.0 million for licensing fees, which was recorded as research and development expense.

Under the amended and restated license agreement with CyDex, the Company agreed to make milestone payments on the achievement

of clinical development and regulatory milestones in the amount of up to $0.8 million in clinical milestones and up to $3.8 million in regulatory
milestones for each of the first two fields with respect to brexanolone; up to $1.3 million in clinical milestones and up to $8.5 million in
regulatory milestones for each of the third and fourth fields with respect to brexanolone; and up to $0.8 million in clinical milestones and up to
$1.8 million in regulatory milestones for one field with respect to SAGE-689. As of December 31, 2020, the Company has recorded research
and development expense and made cash payments of $2.3 million related to these clinical development and regulatory milestones; has
recorded research and development expense and accrued expenses of $1.3 million related to these clinical development milestones and has
recorded an intangible asset and made a cash payment of $3.0 million related to these regulatory milestones.

For the year ended December 31, 2018, additional clinical development milestones were met for the brexanolone program under the

license agreement with CyDex, and accordingly, the Company recorded research and development expense and made cash payments totaling
$0.8 million.

For the year ended December 31, 2019, the Company recorded an intangible asset of $3.0 million related to a regulatory milestone for

the brexanolone program under the license agreement with CyDex.  

For the year ended December 31, 2020, additional clinical development milestones were met for the brexanolone program under the
license agreement with CyDex, and accordingly, the Company recorded research and development expense and accrued expenses totaling $1.3
million.

As of December 31, 2020, the Company has made no milestone payments related to clinical development or regulatory milestones for

SAGE-689 under the license agreement with CyDex.

University of California License Agreements

In October 2013, the Company entered into a non-exclusive license agreement with the Regents under which the Company was granted

a non-exclusive license to certain clinical data and clinical material related to brexanolone for use in the development and commercialization of
biopharmaceutical products in the licensed field, including status epilepticus and postpartum depression. In May 2014, the license agreement
was amended to add the treatment of essential tremor to the licensed field of use, materials and milestone fee provisions of the agreement. The
Company paid to the Regents clinical development milestones of $0.1 million prior to December 31, 2015; no other milestones are outstanding
under this non-exclusive license agreement. The Company is required to pay royalties of less than 1% on net sales for a period of fifteen years
following the sale of the first product developed using the data and materials. The license will terminate on the earlier to occur of (i) 27 years
after the effective date or (ii) 15 years after the last-derived product is first commercially sold.

F-24

 
 
In June 2015, the Company entered into an exclusive license agreement with the Regents whereby the Company was granted an

exclusive license to certain patent rights related to the use of allopregnanolone to treat various diseases. In exchange for such license, the
Company paid an upfront payment of $50,000 and will make payments of $15,000 for annual maintenance fees until the calendar year
following the first sale, if any, of a licensed product. The Company is obligated to make milestone payments following the achievement of
specified regulatory and sales milestones of up to $0.7 million and $2.0 million in the aggregate, respectively. Following the first sale of a
licensed product, the Company is required to pay royalties at a low single digit percentage of net sales of licensed products, subject to specified
minimum annual royalty amounts. Unless terminated by operation of law or by acts of the parties under the terms of the agreement, the license
agreement will terminate when the last-to-expire patents or last-to-be abandoned patent applications expire, whichever is later. As of
December 31, 2020, the Company has recorded research and development expense and made cash payments of $0.3 million related to these
regulatory and sales milestones; and has recorded an intangible asset and made a cash payment of $0.5 million related to these regulatory and
sales milestones.

For the year ended December 31, 2018, the Company recorded research and development expense and made cash payments of $0.2

million related to regulatory milestones under the license agreements with the Regents.

For the year ended December 31, 2019, the Company recorded an intangible asset and made a cash payment of $0.5 million related to a

regulatory milestone under the license agreements with the Regents.

For the year ended December 31, 2020, the Company did not record any expense or make any milestone or royalty payments under the

license agreements with the Regents.

Washington University License Agreement

In November 2013, the Company entered into a license agreement with Washington University whereby the Company was granted

exclusive, worldwide rights to develop and commercialize a novel set of neuroactive steroids developed by Washington University. In
exchange for development and commercialization rights, the Company paid an upfront, non-refundable payment of $50,000 and is required to
pay an annual license maintenance fee of $15,000 on each subsequent anniversary date, until the first Phase 2 clinical trial for a licensed
product is initiated. The Company is obligated to make milestone payments to Washington University based on achievement of clinical
development and regulatory milestones of up to $0.7 million and $0.5 million, respectively. Additionally, the Company fulfilled its obligation
to issue to Washington University 47,619 shares of common stock on December 13, 2013. The fair value of these shares of $0.1 million was
recorded as research and development expense in 2013. As of December 31, 2020, the Company has recorded research and development
expense and made a cash payment of $50,000 related to these clinical development milestones.

The Company is obligated to pay royalties to Washington University at rates in the low single digits on net sales of licensed products

covered under patent rights and royalties at rates in the low single digits on net sales of licensed products not covered under patent rights.
Additionally, the Company has the right to sublicense and is required to make payments at varying percentages of sublicensing revenue
received, initially in the mid-teens and descending to the mid-single digits over time.

For the years ended December 31, 2020, 2019 and 2018, the Company did not record any expense or make any milestone payments

under the license agreement with Washington University.

Collaboration Agreements

Shionogi

In June 2018, the Company entered into a strategic collaboration with Shionogi for the clinical development and commercialization of

zuranolone for the treatment of major depressive disorder (“MDD”) and other potential indications in Japan, Taiwan and South Korea (“the
Existing Partner Territory”). In October 2018, the Company entered into a supply agreement with Shionogi for zuranolone clinical material.

F-25

 
Under the terms of the collaboration agreement, Shionogi will be responsible for all clinical development, regulatory filings and
commercialization of zuranolone for MDD, and potentially other indications, in the Existing Partner Territory. Shionogi was required to make
an upfront payment to the Company of $90.0 million, and the Company will be eligible to receive additional payments of up to $485.0 million
if certain regulatory and commercial milestones are achieved by Shionogi. The potential future milestone payments include up to $70.0 million
for the achievement of specified regulatory milestones, up to $30.0 million for the achievement of specified commercialization milestones, and
up to $385.0 million for the achievement of specified net sales milestones. The Company is eligible to receive tiered royalties on sales of
zuranolone in the Existing Partner Territory, if development efforts are successful, with tiers averaging in the low to mid-twenty percent range,
subject to other terms of the agreement. Shionogi has also granted to the Company certain rights to co-promote zuranolone in Japan. The
Company maintains exclusive rights to develop and commercialize zuranolone outside of the Existing Partner Territory. The upfront cash
payment and any payments for milestones and royalties are non-refundable and non-creditable. Due to the uncertainty of pharmaceutical
development and the high historical failure rates generally associated with drug development, the Company may not receive any milestone
payments or any royalty payments from Shionogi.

The Company concluded that Shionogi meets the definition to be accounted for as a customer because the Company is delivering
intellectual property and know-how rights for the zuranolone program in support of territories in which the parties are not jointly sharing the
risks and rewards. In addition, the Company determined that the Shionogi collaboration met the requirements to be accounted for as a contract,
including that it was probable that the Company will collect the consideration to which the Company was entitled in exchange for the goods or
services that will be delivered to Shionogi.

In determining the appropriate amount of revenue to be recognized under Topic 606, the Company performed the following steps: (i)

identified the promised goods or services in the contract; (ii) determined whether the promised goods or services are performance obligations
including whether they are distinct in the context of the contract; (iii) measured the transaction price, including the constraint on variable
consideration; (iv) allocated the transaction price to the performance obligations; and (v) recognized revenue when (or as) the Company
satisfied each performance obligation.

The Company determined that the performance obligations in the contract included the license to zuranolone and the supply of certain

materials during the clinical development phase, which includes the supply of active pharmaceutical ingredient, or API. The performance
obligation related to the license to zuranolone was determined to be distinct from other performance obligations and therefore was a separate
performance obligation for which control was transferred upon signing. The obligation to provide certain clinical materials, including API for
use during the development period, was determined to be a separate performance obligation.  Given that Shionogi is not obligated to purchase
any minimum amount or quantities of commercial API, the supply of API to Shionogi for commercial use was determined to be an option for
Shionogi, rather than a performance obligation of the Company at contract inception and will be accounted for if and when exercised.  The
Company also determined that there was no separate material right in connection with the supply of API for commercial use as the expected
pricing was not at a discount. Given this fact pattern, the Company has concluded the agreement has two performance obligations.

Under the clinical supply agreement, the Company will manufacture and supply to Shionogi (i) clinical quantities of API reasonably

required by Shionogi for the development of licensed products in the Shionogi territory under the collaboration and license agreement and (ii)
quantities of drug product reasonably required for use by Shionogi in Phase 1 clinical trials of zuranolone in the Shionogi territory under the
collaboration and license agreement, in the quantities agreed to by the parties. Collaboration revenue from the clinical supply agreement, which
excludes the $90.0 million upfront payment, pertains to the clinical material sold under the terms of the clinical supply agreement. The
Company records the costs related to the clinical supply agreement in research and development expense on its consolidated statements of
operations and comprehensive income (loss).

The Company completed the evaluation of the standalone selling prices of each of the performance obligations and determined that the
standalone selling price of the license performance obligation was $90.0 million. The Company recognized the transaction price allocated to
the license performance obligation of $90.0 million as revenue during the quarter upon delivery of the license to Shionogi and resulting ability
of Shionogi to use and benefit from the license, which was in the three months ended June 30, 2018. The remaining transaction price related to
the performance obligation for the supply of certain clinical material is not significant. The potential milestone payments that the Company is
eligible to receive were excluded from the transaction price, as all milestone amounts were fully constrained based on the

F-26

 
 
probability of achievement. The Company will re-evaluate the transaction price at the end of each reporting period and as uncertain events are
resolved or other changes in circumstances occur, and, if necessary, adjust its estimate of the transaction price.

Biogen

In November 2020, the Company entered into a global collaboration and license agreement with Biogen (the “Biogen Collaboration

Agreement”) to jointly develop and commercialize SAGE-217 products for MDD, PPD and other disorders and SAGE-324 products for
essential tremor and other disorders. Concurrently, the Company also entered into a Stock Purchase Agreement with BIMA (the “Biogen Stock
Purchase Agreement”) to purchase shares of the Company’s common stock. The Biogen Collaboration Agreement became effective on
December 28, 2020 (the “Effective Date”).

Under the terms of the Biogen Collaboration Agreement, the Company granted Biogen co-exclusive licenses to develop and

commercialize SAGE-217 products and SAGE-324 products (each, a “Product Class” and together, the “Licensed Products”) in the U.S., an
exclusive license to develop and commercialize SAGE-217 products in all countries of the world other than the Existing Partner Territory (the
“Biogen Territory”), and an exclusive license to develop and commercialize SAGE-324 products in all countries of the world other than the
U.S.

In connection with the effectiveness of the Biogen Collaboration Agreement and the closing of the sale of shares to Biogen in December
2020, the Company received $1.5 billion in consideration, comprised of an upfront payment of $875.0 million and the $650.0 million purchase
price for 6,241,473 newly issued shares of the Company’s common stock (the “Biogen Shares”).

The Company is eligible to receive additional payments of up to $1.6 billion if certain regulatory and commercial milestones are

achieved. The potential future milestone payments for SAGE-217 products include up to $475.0 million for the achievement of specified
regulatory and commercial milestones and up to $300.0 million for the achievement of specified net sales milestones. The potential future
milestone payments for SAGE-324 products include up to $520.0 million for the achievement of specified regulatory and commercial
milestones and up to $300.0 million for the achievement of specified net sales milestones. The Company is also eligible to receive tiered
royalties on net sales of SAGE-217 products and SAGE-324 products in the Biogen Territory at percentage rates ranging from the high teens to
low twenties.

Due to the uncertainty of pharmaceutical development and the high historical failure rates generally associated with drug development,

the Company may never receive any milestone payments or any royalty payments under the Biogen Collaboration Agreement.

Development and commercialization activities in the U.S. will be conducted pursuant to plans agreed to by the Company and Biogen

and overseen by a joint steering committee that will consist at all times of an equal number of representatives of each party. The Company and
Biogen will share equally in the costs for development and commercialization, as well as the profits and losses, in the U.S., subject to the
Company’s opt-out right described below. Biogen will be solely responsible for all development activities and costs related to any development
and commercialization of SAGE-217 products and SAGE-324 products for the Biogen Territory and the Company will receive royalties on any
sales in the Biogen Territory, as mentioned above.

The Company will supply API and bulk drug product for the Biogen Territory and active pharmaceutical ingredient and final bulk drug

product for the U.S. to support development and commercialization activities. Biogen has the right to assume manufacturing responsibilities for
active pharmaceutical ingredient at any time during the agreement and will, within a reasonable period of time after the Effective Date, assume
manufacturing responsibility for bulk drug product for the Biogen Territory.

Unless terminated earlier, the Biogen Collaboration Agreement will continue on a Licensed Product-by-Licensed Product and country-
by-country basis until the date on which (a) in any country in the Biogen Territory, the royalty term has expired for all Licensed Products in a
Product Class in such country, and (b) for the U.S., the parties agree to permanently cease to commercialize all Licensed Products in a Product
Class. Biogen also has the right to terminate the

F-27

 
 
 
 
 
 
 
 
 
Biogen Collaboration Agreement for convenience upon advance written notice. The Company has an opt-out right to convert the co-exclusive
licenses in the U.S. to an exclusive license to Biogen on a Product Class-by-Product Class basis. Following the exercise of the opt-out right, the
Company would no longer share equally in the profits and losses in the U.S. and would be entitled to receive certain royalty payments at
percentage rates ranging from the high teens to low twenties additional sales milestones.

The Company concluded that the Biogen Collaboration Agreement and the Biogen Stock Purchase Agreement should be combined and

treated as a single arrangement for accounting purposes as the agreements were entered into contemporaneously and in contemplation of one
another. The Company determined that the combined agreements had elements that were within the scope of Topic 606 and Topic 808.

As of the Effective Date, the Company identified the following promises in the Biogen Collaboration Agreement that were evaluated

under the scope of Topic 606: delivery of (i) a co-exclusive license for SAGE-217 products in the U.S.; (ii) an exclusive license for SAGE-217
products in the Biogen Territory; (iii) a co-exclusive license for SAGE-324 products in the U.S.; (iv) an exclusive license for SAGE-324
products in all countries of the world other than the U.S.; (v) the clinical manufacturing supply of active pharmaceutical ingredient and bulk
drug product for SAGE-217 products in the Biogen Territory; and (vi) the clinical manufacturing supply of active pharmaceutical ingredient
and bulk drug product for SAGE-324 products in the Biogen Territory.

The Company also evaluated whether certain options outlined within the Biogen Collaboration Agreement represented material rights

that would give rise to a performance obligation and concluded that none of the options convey a material right to Biogen and therefore are not
considered separate performance obligations within the Biogen Collaboration Agreement.

The Company assessed the above promises and determined that the co-exclusive licenses for SAGE-217 products and SAGE-324
products in the U.S. are reflective of a vendor-customer relationship and therefore represent performance obligations within the scope of Topic
606. The co-exclusive license for SAGE-217 products and SAGE-324 products in the U.S. are considered functional intellectual property and
distinct from other promises under the contract. The exclusive licenses for SAGE-217 products and SAGE-324 products in the Biogen
Territory are considered functional licenses that are distinct in the context of the Biogen Collaboration Agreement as Biogen can benefit from
the licenses on its own or together with other readily available resources. As the co-exclusive licenses in the U.S. and the exclusive licenses in
the Biogen Territory are delivered at the same time, they are considered one performance obligation at contract inception. The clinical
manufacturing supply of active pharmaceutical ingredient and bulk drug product for SAGE-217 products and SAGE-324 products for the
Biogen Territory are considered distinct in the context of the Biogen Collaboration Agreement as Biogen can benefit from the manufacturing
services together with the licenses transferred by the Company at the inception of the agreement. Therefore, each represents a separate
performance obligation within a contract with a customer under the scope of Topic 606 at contract inception.

The Company considers the collaborative activities associated with the co-development, co-commercialization, and co-manufacturing of

SAGE-217 products and SAGE-324 products in the U.S. to be separate units of account within the scope of Topic 808 as the Company and
Biogen are both active participants in the development and commercialization activities and are exposed to significant risks and rewards that
are dependent on the development and commercial success of the activities in the arrangement. 

The Company determined the transaction price under Topic 606 at the inception of the Biogen Collaboration Agreement to be $1.1
billion, consisting of the upfront payment of $875.0 million plus $232.5 million in excess proceeds from the equity investment under the
Biogen Stock Purchase Agreement, when measured at fair value, plus future variable consideration for manufacturing supply of clinical active
pharmaceutical ingredient and bulk drug product for the Biogen Territory. The amount of variable consideration related to the future
manufacturing services was not material. The Company determined that any variable consideration related to clinical development and
regulatory milestones is deemed to be fully constrained and therefore excluded from the transaction price due to the high degree of uncertainty
and risk associated with these potential payments, as the Company determined that it could not assert that it was probable that a significant
reversal in the amount of cumulative revenue recognized will not occur. The Company also determined that

F-28

 
 
 
 
 
 
 
royalties and sales milestones relate solely to the licenses of intellectual property and are therefore excluded from the transaction price under
the sales- or usage-based royalty exception of Topic 606. Revenue related to these royalties and sales milestones will only be recognized when
the associated sales occur, and relevant thresholds are met.

As noted above, the Company identified three performance obligations in the Biogen Collaboration Agreement: (i) the delivery of the

co-exclusive licenses for SAGE-217 products and SAGE-324 products in the U.S. and the exclusive licenses for SAGE-217 products and
SAGE-324 products in the Biogen Territory; (ii) the clinical manufacturing supply of active pharmaceutical ingredient and bulk drug product
for SAGE-217 products in the Biogen Territory; and (iii) the clinical manufacturing supply of the active pharmaceutical ingredient and bulk
drug product for SAGE-324 products in the Biogen Territory. The selling price of each performance obligation in the Biogen Collaboration
Agreement was determined based on the Company’s SSP with the objective of determining the price at which it would sell such an item if it
were to be sold regularly on a standalone basis. The Company allocated the variable consideration related to the manufacturing obligations to
the future clinical supply of SAGE-217 products and SAGE 324 products in the Biogen Territory and the remaining fixed consideration to the
license obligation. The variable consideration related to the manufacturing obligations was not material. As such, the entirety of the $1.1 billion
fixed consideration of the transaction price has been allocated to the transfer of the co-exclusive licenses for SAGE-217 products and SAGE-
324 products in the U.S. and the exclusive licenses for SAGE-217 products and SAGE-324 products in the Biogen Territory. The Company
recognizes revenue for the license performance obligations at a point in time, that is upon transfer of the licenses to Biogen. As control of these
licenses was transferred on the Effective Date and Biogen could begin to use and benefit from the licenses, the Company recognized $1.1
billion of license revenue during the year ended December 31, 2020 under the Biogen Collaboration Agreement. The Company will recognize
revenue for the clinical manufacturing supply obligations at a point in time, that is upon the delivery of the supply to Biogen.

Accounting for the Biogen Stock Purchase Agreement

In connection with the execution of the Biogen Collaboration Agreement, the Company and BIMA entered into the Biogen Stock

Purchase Agreement. Pursuant to the Biogen Stock Purchase Agreement, the Company sold the Biogen Shares to BIMA at a price of
approximately $104.14 per share, which represented a 40 percent premium over the 30-day volume-weighted average share price as of the last
trading day prior to the date the Biogen Collaboration Agreement and Biogen Stock Purchase Agreement were executed in November 2020, for
aggregate consideration of $650.0 million. The sale of the shares to BIMA closed on December 31, 2020.

The Biogen Stock Purchase Agreement includes certain standstill provisions, lock-up restrictions, and a voting agreement with respect to

the Biogen Shares. Pursuant to the terms of the Biogen Stock Purchase Agreement, BIMA has agreed not to, and to cause its affiliates not to,
directly or indirectly acquire the Company’s securities, seek or propose a tender or exchange offer or merger between the Company and
Biogen, solicit proxies or consents with respect to any matter, or undertake other specified actions, in each case subject to specified conditions.
The standstill restrictions terminate on the earliest of (i) a specified regulatory milestone under the Biogen Collaboration Agreement, (ii) the
date one year following the termination of the Biogen Collaboration Agreement and (iii) the seventh anniversary of the Effective Date. BIMA
has also agreed not to, and to cause its affiliates not to, sell or transfer any of the Biogen Shares for a period of eighteen months and to limit
sales and transfers of the Biogen Shares for an additional eighteen month period, in each case subject to specified conditions and exceptions.

F-29

 
 
 
 
 
The Company determined the fair value of the common shares issued using an option pricing valuation model to take into consideration
the holding period restrictions. The fair value of the Company’s common stock was considered a level 2 fair value measurement within the fair
value hierarchy. The most significant assumptions within the model are the Company’s stock price, the term of the restrictions and the stock
price volatility, which is based upon a blend of historical and implied volatility of the Company’s stock. Based on the fair value adjustments
made by management, the fair value of the shares issued was determined to be $417.5 million, which was $232.5 million less than the proceeds
received from BIMA for the issuance of the Company’s common stock under the Biogen Stock Purchase Agreement. As such, the $232.5
million in excess proceeds has been included in the $1.1 billion transaction price of the Biogen Collaboration Agreement determined above.

Preferred Stock

The Board of Directors of the Company is authorized, without action by the stockholders, to designate and issue up to an aggregate of

5,000,000 shares of preferred stock in one or more series. The Board of Directors of the Company can designate the rights, preferences and
privileges of the shares of each series and any of its qualifications, limitations or restrictions. The Board of Directors of the Company 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. As of December 31, 2020 and 2019, the Company had no shares of preferred stock issued or outstanding and
preferred stock was classified as stockholders’ equity.

8.

Common Stock

As of December 31, 2020 and 2019, the Company authorized 120,000,000 shares of common stock with a par value of $0.0001 per

share.

Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common

stockholders are entitled to receive dividends, as may be declared by the Board of Directors, if any. As of December 31, 2020 and 2019, no
dividends have been declared.

On February 13, 2018, the Company completed the sale of 4,032,012 shares of its common stock at a price to the public of $164.00 per
share, resulting in net proceeds to the Company of $631.2 million after deducting underwriting discounts and commissions and offering costs
paid by the Company.

On February 27, 2019, the Company completed the sale of 3,833,334 shares of its common stock at a price to the public of $150.00 per
share, resulting in net proceeds to the Company of $560.9 million after deducting underwriting discounts and commissions and offering costs
paid by the Company.

On December 31, 2020, the Company completed the sale of 6,241,473 shares of its common stock in a private placement to Biogen at a

price to the public of approximately $104.14 per share, resulting in aggregate gross proceeds to the Company of $650.0 million.

As of December 31, 2020, the Company had received 3,033 shares of the Company’s common stock from a then employee as proceeds

for exercises of stock options.  The total cost of shares held in treasury at December 31, 2020 was $0.4 million.

Stock-Based Compensation

Equity Plans

On July 2, 2014, the stockholders of the Company approved the 2014 Stock Option and Incentive Plan (the “2014 Plan”), which became
effective immediately prior to the completion of the Company’s IPO. The 2014 Plan provides for the grant of restricted stock awards, restricted
stock units, incentive stock options and non-statutory stock options. The 2014 Plan replaced the Company’s 2011 Stock Option and Grant Plan
(the “2011 Plan”). The Company no longer grants stock options or other awards under its 2011 Plan, but any options outstanding under the
2011 Plan remain outstanding and effective in accordance with their terms.

F-30

 
 
The 2014 Plan provides for an annual increase, to be added on the first day of each fiscal year, by up to 4% of the Company’s

outstanding shares of common stock as of the last day of the prior year.  On January 1, 2020, 2,075,087 shares of common stock, representing
4% of the Company’s outstanding shares of common stock as of December 31, 2019, were added to the 2014 Plan.

On December 15, 2016, the Board of Directors of the Company (the “Board”) approved the 2016 Inducement Equity Plan (as amended

and restated, the “2016 Plan”). The 2016 Plan provides for the grant of equity awards to individuals who have not previously been an employee
or a non-employee director of the Company to induce them to accept employment and to provide them with a proprietary interest in the
Company. On September 20, 2018, the Board amended the 2016 Plan to increase the total number of shares reserved for issuance by 1,200,000
shares.

Terms of equity grants, including vesting requirements, are determined by the Board or the Compensation Committee of the Board,

subject to the provisions of the applicable plan. Options granted by the Company, that are not performance-based, are considered time-based
because they generally vest based on the continued service of the grantee with the Company during a specified period following grant. These
awards, when granted to employees, generally vest ratably over four years, with 25% cliff vesting at the one-year anniversary. All option
awards expire in 10 years after the date of grant.

As of December 31, 2020, the total number of shares reserved under all equity plans was 12,535,574 and the total number of shares

available for future issuance under all equity plans was 4,420,049 shares.

During the year ended December 31, 2017, the Company granted 32,500 time-based restricted stock units to certain employees of the

Company. The Company did not grant time-based restricted stock units prior to January 1, 2017.  These time-based restricted stock units vested
ratably over two years, with vesting of 50% at both the one-year and two-year anniversary of the grant date, which was in February 2018 and
2019, respectively. The fair value of the time-based restricted stock units that vested during the years ended December 31, 2019 and 2018 was
$2.0 million and $2.6 million, respectively. No time-based restricted stock units vested during the year ended December 31, 2020.

During the year ended December 31, 2020, the Company granted 550,890 time-based restricted stock units to certain employees of the
Company. These time-based restricted stock units will vest over two years, with 25% vesting at the one-year anniversary of the grant date and
75% vesting at the two-year anniversary of the grant date, which will be in April 2021 and April 2022, respectively.  During the years ended
December 31, 2019 and 2018, the Company granted no time-based restricted stock units.

During the year ended December 31, 2018, the Company granted 71,400 performance restricted stock units to certain employees of the

Company. The milestones for these grants were not met, and accordingly, these grants were cancelled.

During the year ended December 31, 2019, the Company granted 393,539 performance restricted stock units to employees of the
Company. These performance restricted stock units are related to the achievement of certain clinical and regulatory development milestones
related to product candidates and commercial milestones.

During the year ended December 31, 2020, the Company granted 471,386 performance restricted stock units to employees of the
Company. These performance restricted stock units are related to the achievement of certain clinical and regulatory development milestones
related to product candidates and commercial milestones.

Recognition of stock-based compensation expense associated with performance restricted stock units commences when the performance

condition is considered probable of achievement, using management’s best estimates, which consider the inherent risk and uncertainty
regarding the future outcomes of the milestones.

During the year ended December 31, 2019, one milestone for grants of performance restricted stock units was achieved. This milestone

represents 18% of the performance restricted stock units that were granted during the year ended December 31, 2019.  The fair value of
performance restricted stock units that vested during the year ended December 31, 2019 was $11.1 million.

No performance restricted stock units vested during the years ended December 31, 2020 and 2018.

At December 31, 2020, 957,695 restricted stock units were both outstanding and unvested, and the total unrecognized stock-based

compensation expense related to those awards was $58.2 million.

Performance-Based Stock Options

During the year ended December 31, 2018, the Company granted 524,003 options to employees to purchase shares of common stock that

contain performance-based vesting criteria, primarily related to the achievement of certain clinical and regulatory development milestones
related to product candidates and commercial milestones. During the years ended December 31, 2020 and 2019, the Company granted no
options to employees to purchase shares of common stock that contain performance-based vesting criteria.  

Recognition of stock-based compensation expense associated with performance-based stock options commences when the performance

condition is considered probable of achievement, using management’s best estimates, which consider the inherent risk and uncertainty
regarding the future outcomes of the milestones.

During the year ended December 31, 2018, a milestone was achieved under a stock option granted to a consultant. The milestone was

related to the consummation of a licensing or corporate partnering arrangement.  During the year ended December 31, 2018, the Company
recognized stock-based compensation expense related to this milestone of $6.9 million.

During the year ended December 31, 2018, one milestone was achieved under stock options granted to employees. This milestone

represents 33% of the performance-based options that were granted during the year ended December 31, 2017. During the year ended
December 31, 2018, the Company recognized stock-based compensation expense related to this milestone of $4.4 million.  

During the year ended December 31, 2018, the remaining milestone for the performance-based option grants that were made during the

years ended December 31, 2016 and December 31, 2015 was not met, and accordingly, those options were cancelled.  This milestone
represents 50% and 35% of the performance-based option grants that were made during the years ended December 31, 2016 and December 31,
2015, respectively.  The Company recognized no stock-based compensation expense related to this milestone.

During the year ended December 31, 2019, one commercial milestone was achieved under stock options granted to employees. Stock

options with this milestone were granted during the years ended December 31, 2018 and 2017, respectively. This milestone represents 20% and
33% of the performance-based option grants that were made during the years ended December 31, 2018 and 2017, respectively. During the
year ended December 31, 2019, the Company recognized stock-based compensation expense related to this milestone of $16.3 million.

During the year ended December 31, 2020, no milestones were achieved under performance-based options. During the year ended
December 31, 2020, one milestone for the performance-based option grants that were made during the year ended December 31, 2018 was not
met, and accordingly, those options were cancelled.  This milestone represents 19% of the performance-based option grants that were made
during the year ended December 31, 2018.  The Company recognized no stock-based compensation expense related to this milestone.

As of December 31, 2020, 2019 and 2018, for performance-based option grants that were outstanding, the achievement of the milestones

that had not been met that are the criteria for vesting of performance-based stock options was not considered probable, and therefore no
expense has been recognized related to these awards in the years ended December 31, 2020, 2019 and 2018, respectively.

The stock-based compensation expense recorded for the restructuring in the year ended December 31, 2020 is the incremental amount

related to modifying the exercise period for outstanding, vested option grants that had been made to employees who were terminated in the
restructuring.

For stock option awards, the fair value is estimated at the grant date using the Black-Scholes option-pricing model, taking into account

the terms and conditions upon which options are granted. The fair value of the options is amortized on a straight-line basis for awards to
employees over the requisite service period of the awards. For awards to non-employees, the fair value of the options was amortized on a
graded basis through December 31, 2018, and starting on January 1, 2019, on a straight-line basis, over the requisite service period of the
awards.

The weighted average grant date fair value per share of stock options granted under the Company’s stock option plans during the years

ended December 31, 2020, 2019 and 2018 was $37.53, $82.39 and $109.92, respectively.

The fair value of each option granted under the Company’s equity plans has been calculated on the date of grant using the following

weighted average assumptions:

Expected dividend yield: the Company has not paid, and does not anticipate paying, any dividends in the foreseeable future.

Risk-free interest rate: the Company determined the risk-free interest rate by using a weighted average equivalent to the expected term

based on the U.S. Treasury yield curve in effect as of the date of grant.

Expected volatility: through December 31, 2015, the Company lacked sufficient Company-specific historical and implied volatility

information, and as a result, the Company used the volatility of a group of publicly-traded peer companies in the Black-Scholes
calculations.  Beginning in 2016, the Company estimated its expected volatility using a weighted average of the historical volatility of publicly-
traded peer companies and the volatility of its common stock and expected to continue to do so until such time as it has adequate historical data
regarding the volatility of its common stock price for the duration of the expected term. Effective January 1, 2020, the Company began using
the historical volatility of only its common stock, as there is adequate historical data for the duration of the expected term.

Expected term (in years): the expected term represents the period that the Company’s stock option grants are expected to be outstanding.

The expected term of the options granted to employees and non-employee directors by the Company has been determined utilizing the
“simplified” method for awards that qualify as “plain-vanilla” options. Through December 31, 2018, the expected term of the options granted
to non-employee consultants was determined based on the contractual term of the options, and since January 1, 2019, the “simplified” method
has been used. Under this approach, the weighted average expected life is presumed to be the average of the vesting term and the contractual
term of the option.

Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from estimates.
The Company estimates forfeitures based on historical terminations. For the years ended December 31, 2020, 2019 and 2018, the weighted-
average forfeiture rates were 20.6%, 13.7% and 10.7%, respectively.

Through December 31, 2018, for options granted to non-employees, the expected term is 10 years, which is the contractual term of each
option. All other assumptions used to calculate the grant date fair value for non-employees are generally consistent with the assumptions used
for options granted to employees.

2014 Employee Stock Purchase Plan

On July 2, 2014, the Company’s stockholders approved the 2014 Employee Stock Purchase Plan, which had been previously approved

by the Board of Directors. The 2014 Employee Stock Purchase Plan became effective upon the completion of the IPO. A total of 282,000
shares of common stock were authorized for issuance under this plan. As of December 31, 2020, 177,879 shares have been issued under this
plan and 104,121 shares are available for issuance under this plan. At December 31, 2020, accrued expenses includes $0.3 million of stock-
based compensation expense related to an enrollment period for which the related shares had not been issued as of December 31, 2020.

There is no current or deferred provision for income taxes because the Company had historically incurred operating losses prior to the

year ended December 31, 2020, which it has used to reduce both federal and state taxable income for the year ended December 31, 2020. As of
December 31, 2020, the Company continues to maintain a full valuation

allowance against its net deferred tax assets. The reported amount of income tax expense for the years differs from the amount that would result
from applying domestic federal statutory tax rates to pretax losses primarily because of changes in valuation allowance.

A reconciliation of the U.S. statutory rate to the Company’s effective tax rate is as follows:

Tax due at statutory rate
State taxes, net of federal
Biogen transaction-related items
Stock-based compensation
Foreign rate differential
Federal and state credits
Change in valuation allowance

As of December 31, 2020, the Company had federal and state net operating loss carryforwards of $41.7 million and $438.4 million,
respectively, which begin to expire in 2033. As of December 31, 2020, the Company had additional federal net operating loss carryforwards of
$886.1 million that do not expire. As of December 31, 2020, the Company had federal and state research and development tax credits
carryforwards of $40.7 million and $9.4 million, respectively, which begin to expire in 2031. As of December 31, 2020, the Company had
federal orphan drug tax credit carry forwards of $42.3 million, which begin to expire in 2034.

In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (“the CARES Act”) was signed into
law in the U.S. in March 2020. The CARES Act adjusted a number of provisions of the tax code, including the calculation and eligibility of
certain deductions and the treatment of net operating losses and tax credits. The

enactment of the CARES Act did not result in any material adjustment to the income tax provision for the year ended December 31, 2020, or to
the net deferred tax assets as of December 31, 2020.

As of December 31, 2020, net deferred tax assets before the valuation allowance decreased $107.2 million, primarily due to the
utilization of federal and state net operating loss carryforwards to reduce federal and state taxable income for the year ended December 31,
2020. This decrease in net deferred tax assets was offset by a corresponding decrease in the valuation allowance.

Management of the Company has evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets,

which are comprised principally of federal and state net operating loss and tax credit carryforwards. Under the applicable accounting standards,
management has considered the Company’s history of losses and concluded that it is more likely than not that the Company will not recognize
the benefits of its federal and state deferred tax assets. Accordingly, a full valuation allowance of $376.1 million and $483.3 million has been
established at December 31, 2020 and 2019, respectively. The valuation allowance decreased by $107.2 million, increased by $174.9 million
and increased by $102.9 million for the years ended December 31, 2020, 2019 and 2018, respectively, primarily due to utilization or generation
of net operating losses.

Pursuant to Section 382 of the Internal Revenue Code, and similar state tax law, certain substantial changes in the Company’s ownership

may result in a limitation on the amount of net operating loss and tax credit carryforwards that may be used in future years. Utilization of the
net operating loss and tax credit carryforwards may be subject to a substantial annual limitation under Section 382 of the Internal Revenue
Code of 1986 due to ownership change limitations that have occurred previously or that could occur in the future. These ownership changes
may limit the amount of net operating loss and tax credit carryforwards that can be utilized annually to offset future taxable income and tax,
respectively. The Company completed a Section 382 study through December 31, 2020. Based on the study, the Company underwent two
ownership changes for Section 382 purposes which occurred on March 11, 2014 and December 31, 2015. As a result of the ownership changes,
the Company’s net operating loss and tax credit carryforwards as of the ownership change dates are subject to limitation under Section 382;
however, these limitations are not expected to cause any of the impacted net operating loss and tax credit carryforwards to expire unused. Any
net operating losses or tax credits generated after the December 2015 change are not subject to this annual limitation. However, subsequent
ownership changes, as defined by Section 382, may potentially further limit the amount of net operating loss and tax credit carryforwards that
could be utilized to offset future taxable income and tax.

The Company applies the authoritative guidance on accounting for and disclosure of uncertainty in tax positions, which requires the
Company to determine whether a tax position of the Company is more likely than not to be sustained upon examination, including resolution of
any related appeals of litigation processes, based on the technical merits of the position. For tax positions meeting the more likely than not
threshold, the tax amount recognized in the financial statements is reduced by the largest benefit that has a greater than fifty percent likelihood
of being realized upon the ultimate settlement with the relevant taxing authority. 

At December 31, 2020, 2019 and 2018, the Company had no unrecognized tax benefits.

The Company’s policy is to record interest and penalties related to income taxes as part of the tax provision. As of December 31, 2020
and 2019, the Company had no accrued interest or penalties related to income taxes and no amounts have been recognized in the Company’s
statement of operations.

The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business,

the Company is subject to examination by federal, state and foreign jurisdictions, where applicable. There are currently no pending tax
examinations, and the Company’s tax returns are generally open under statute from 2017 to the present. Tax attributes such as net operating
losses and tax credits generated prior to 2017 and utilized in open years may still be adjusted upon examination.

Employee Benefit Plan

The Company maintains a 401(k) profit sharing plan (the “Plan”) for its employees. Each employee may elect to contribute a portion of

his or her compensation to the Plan, subject to annual limits established by the Internal Revenue Service. For the years ended December 31,
2020, 2019 and 2018, the Company matched 50% of eligible contributions to the Plan up to 6% of employee contributions. For the years ended
December 31, 2020, 2019 and 2018 the Company contributed to the Plan $2.2 million, $3.6 million and $1.8 million, respectively.

13. Restructuring

In April 2020, the Company announced a restructuring plan to enable the Company to advance its corporate strategy and pipeline that

included the elimination of approximately 53% of the Company’s workforce. The workforce reduction primarily affected the ZULRESSO
commercial operation and related selling, general and administrative support functions. During the year ended December 31, 2020, the
Company recorded $27.7 million of expense for restructuring, primarily for one-time termination benefits to the affected employees, primarily
for cash payments of severance, healthcare benefits and outplacement assistance.  Substantially all of the accrued restructuring charges were
paid in cash as of December 31, 2020.

Restructuring activity during the year ended December 31, 2020 was as follows:

Such amounts will be determined consistent with a Selling Party’s customary practices and in accordance with GAAP.  It
is understood that any accruals for individual items reflected in Net Sales are periodically (at least [**]) trued up and adjusted by
each Selling Party consistent with its customary practices and in accordance with GAAP.

Notwithstanding anything to the contrary set forth in this Agreement, [**].

In  the  case  of  any  Combination  Product  sold  in  a  given  country  and  reporting  period,  Net  Sales  for  the  purpose  of
determining  royalties  and  Sales  Milestone  Events  of  the  Combination  Product  in  such  country  will  be  calculated  by  multiplying
actual  Net  Sales  of  such  Combination  Product  by  the  fraction  A/(A+B),  where  A  is  the  invoice  price  of  the  applicable  Sage
Molecule if sold separately in the same indication in such country, and B is the total invoice price of the Other Components in the
Combination Product, if sold separately in the same indication in such country.

indication in a country, but the Other Components in the Combination Product are not sold separately in the same indication in such
country, then Net Sales for the purpose of determining royalties and Sales Milestone Events of the Combination Product for such
country will be calculated by multiplying actual Net Sales of the Combination Product by the fraction A/C, where A is the invoice
price of the Sage Molecule if sold separately in the same indication in such country, and C is the invoice price of the Combination
Product in such country.

If, on a country-by-country basis in a particular reporting period, the Licensed Product in the Combination Product is not
sold  separately  in  the  same  indication  in  such  country,  but  the  Other  Components  included  in  the  Licensed  Product  are  sold
separately  in  the  same  indication  in  such  country,  then  Net  Sales  for  the  purpose  of  determining  royalties  and  Sales  Milestone
Events of the Combination Product for such country will be calculated by multiplying actual Net Sales of the Combination Product
by  the  fraction  (C-B)/C,  where  B  is  the  invoice  price  of  the  Other  Components  included  in  such  Combination  Product  if  sold
separately in the same indication in such country, and C is the invoice price of the Combination Product in such country.

If neither the Licensed Product nor the Other Components are sold separately in the same indication in a given country

during a particular reporting period, then Net Sales will be calculated based on [**].

Any disputes between the Parties relating to the calculation of Net Sales under this Section 1.1.184 (Net Sales) based on non-cash
consideration or allocation of Net Sales for a Combination Product will be resolved pursuant to the dispute resolution procedures in
Section 15.3.5 (Expert Arbitration).

General. All Development of the Licensed 217 Products and the Licensed 324 Products for the Profit-Share
Territory  will  be  conducted  pursuant  to  a  development  plan  and  budget  for  the  applicable  Product  Class  (each  such  plan,  a  “Joint
Development  Plan”)  that  describes  for  each  Product  Class  for  the  Profit-Share  Territory:  (a)  [**];  (b)  the  anticipated  timelines  for  such
activities, including [**]; (c) the respective roles and responsibilities of each Party in connection with such activities, including which Party
will have day-to-day operational responsibility with respect to such activities for the applicable Licensed Products in the Profit-Share Territory
(for such activity, the “Development Lead Party”); and (d) the associated budget of the FTE Costs and Out-of-Pocket Costs anticipated to be
incurred  in  the  performance  of  the  foregoing  activities  (each  such  included  budget  in  a  Joint  Development  Plan,  a  “Joint  Development
Budget”)  and,  starting  with  the  annual  update  to  the  Joint  Development  Plan  for  2021,  a  [**],  high-level  budget  with  respect  to  the
performance of activities in such Joint Development Plan (each such budget, a “Long Term Joint Development Budget”).  Each Party will be
allocated meaningful responsibility for Development activities under each Joint Development Plan, consistent with a 50:50 collaboration for
the Licensed Products for the Profit-Share Territory.  In the event of any inconsistency between a Joint Development Plan and this Agreement,
the terms of this Agreement will prevail. The initial Joint Development Plan for the Licensed 217 Products and the initial Joint Development

or more often as the Parties deem appropriate, the JDC will prepare amendments to each then-current Joint Development Plan (including the
corresponding  Joint  Development  Budget)  for  the  Licensed  217  Products  and  the  Licensed  324  Products,  and  submit  such  each  such
amendment to the JSC to review, discuss and determine whether to approve by no later than [**]of each Calendar Year, and (b) no later than
[**] of each Calendar Year, or more often as the Parties deem appropriate, the JDC will prepare amendments to each then-current Long Term
Joint Development Budget corresponding to each Joint Development Plan and submit each such amendment to the JSC to review, discuss and

for  the  Commercialization  of  the  Licensed  217  Products  and  the  Licensed  324  Products  for  the  Profit-Share  Territory  will  be  set
forth  in  and  conducted  pursuant  to  a  commercialization  plan  and  budget  for  each  Product  Class  (each  such  plan,  a  “Joint
Commercialization  Plan”)  that  describes  for  each  Product  Class  in  the  Profit-Share  Territory:  (a)  the  pre-launch,  launch  and
subsequent Commercialization activities of the applicable Licensed Products in the Profit-Share Territory, including the field force
size, structure, allocation and deployment; patient support size and structure; product positioning; market access plans; anticipated

have  day-to-day  operational  responsibility  with  respect  to  such  activities  for  the  applicable  Licensed  Product  in  the  Profit-Share
Territory  (for  such  activity,  the  “Commercialization  Lead  Party”);  and  (c)  the  associated  budget  of  the  FTE  Costs  and  Out-of-
Pocket  Costs  anticipated  to  be  incurred  in  the  performance  of  the  foregoing  activities  (each  such  included  budget,  a  “Joint
Commercialization  Budget”)  and  [**],  high-level  budget  with  respect  to  the  performance  of  activities  under  such  Joint
Commercialization Plan (each such budget, a “Long Term Joint Commercialization Budget”). In the event of any inconsistency
between a Joint Commercialization Plan and this Agreement, the terms of this Agreement will prevail.

5.2.1.2

(a) No later than [**] following the Effective Date for the Licensed 217 Products and (b) no later
than [**] following Initiation of the [**] for the first Licensed 324 Product, in each case, in the Profit-Share Territory, the JCC will

Budget  and  Long  Term  Joint  Commercialization  Budget)  and  submit  such  initial  Joint  Commercialization  Plan(s)  to  the  JSC  to
review, discuss and determine whether to approve.

5.2.2

Amendments to Joint Commercialization Plans.  On an annual basis, (a) no later than [**] of each Calendar,
or more often as the Parties deem appropriate, the JCC will prepare amendments to each then-current Joint Commercialization Plan, including
the  corresponding  Joint  Commercialization  Budget,  for  the  Licensed  217  Products  and  the  Licensed  324  Products,  and  submit  each  such

each Calendar Year, or more often as the Parties deem appropriate, the JCC will prepare amendments to each then-current Long Term Joint
Commercialization Budget corresponding to

(General)  for  each  Product  Class  for  the  next  Calendar Year  (and  additional  periods  as  reasonably  determined  by  the  Parties)  and  the  Joint
Commercialization  Budget  included  therein  will  appropriately  itemize  FTE  Costs  and  Out-of-Pocket  Costs  for  the  activities  undertaken
pursuant to such Joint Commercialization Plan.  Once approved by the JSC, an amended annual Joint Commercialization Plan (including its
corresponding  Joint  Commercialization  Budget  and  Long  Term  Joint  Commercialization  Budget)  will  become  effective  for  the  applicable

the  performance  of  such  activities)  and  fails  to  cure  any  such  non-performance  within  [**]  after  receipt  of  written  notice  from  the  non-
Commercialization Lead Party regarding such non-performance, then the other Party will have the right to become the Commercialization Lead
Party with respect to the non-performed activities for purposes of this Agreement, and any FTE Costs and Out-of-Pocket Costs that such other
Party  incurs  in  connection  with  its  performance  of  such  activities  (or  the  assumption  thereof)  will  be  included  as  Joint  Commercialization

employees of Biogen in the Profit-Share Territory are agents or employees of Sage or subject to Sage’s direction and control.  Biogen will have

royalty and other payments to any Third Party in respect of any license agreement or other agreement entered into after the Effective Date in
accordance with the subsections below of this Section 8.3 (Third Party In-Licenses Payments) will be deemed “Third Party Payments” and
be subject to this Section 8.3 (Third Party In-Licenses Payments).

8.3.2.1

New Technology.  After the Effective Date, a Party may wish to acquire a right or license under
additional Patents or Know-How of Third Parties for the Development, Manufacture or Commercialization of Licensed Products for
the Profit-Share Territory (“New Technology”).  With respect to the New Technology for the Profit-Share Territory, such Party will
(a) promptly notify the JSC in writing and keep the JSC reasonably informed of any negotiations

with respect to such right or license, including the proposed terms of any such license, and consider in good faith any comments of
the other Party with respect thereto, and (b) in any event comply with the procedures set forth in Section 8.3.2.2 (Inclusion Process).

8.3.2.2

Inclusion Process. If, after the Effective Date, a Party wishes to acquire rights under any New
Technology that would be Sage Licensed Technology or Biogen Licensed Technology, as applicable, then such Party will so notify
the JSC and provide the JSC with a summary of the terms of any license or agreement, including any Third Party Payments owed to
a Third Party as a result of the grant to the other Party of rights with respect to such New Technology or a Party’s practice or use of

Technology,  as  applicable,  and  one  Party  believes  that  such  New  Technology  is  [**],  then  the  resolution  procedure  of  Section
8.3.2.4 (New Technology Disputes) will apply.  For clarity, with respect to New Technology other than [**], the Party proposing to
acquire rights to such New Technology will have the right to obtain a license to such New Technology, but the other Party will not

Costs  associated  with  such  [**]  to  the  extent  allocable  to  the  Profit-Share  Territory.  Nothing  herein  will  prevent  Biogen  from
obtaining rights (whether by acquisition or license) under any intellectual property right that is necessary or reasonably useful to

8.3.2.4

8.4

No Other Rights.  Except as otherwise expressly provided in this Agreement, under no circumstances will a Party or
any of its Affiliates, as a result of this Agreement, obtain any ownership interest, license or other right (whether by implication, estoppel or
otherwise)  in  or  to  any  Know-How,  Patents  or  other  intellectual  property  rights  of  the  other  Party  or  any  of  such  other  Party’s
Affiliates.  Neither Party nor any of its Affiliates will use or practice any Know-How or Patents licensed or provided to such Party or any of its

Taxes.

9.11.5.1

General. Each Party will be responsible for all Taxes imposed on such Party’s net income, or on
net income allocated to such Party under applicable Law.  To the extent one Party pays Taxes imposed on net income of the other
Party, the other Party will reimburse the paying Party for any such Taxes paid.  The amounts payable pursuant to this Agreement
(“Payments”)  will  not  be  reduced  on  account  of  any  Taxes  unless  required  by  applicable  Law.  A  payor  Party  will  deduct  and
withhold  from  the  Payments  any  Taxes  that  it  is  required  by  applicable  Law  to  deduct  or  withhold  including  from  subsequent
Payments (“Withholding Taxes”), and any such Withholding Taxes shall be treated as having been paid to the payee pursuant to
this Agreement; provided that the payor Party will provide the payee with written notice of the required withholding as promptly as
reasonably  practical  (and  in  any  event,  no  later  than  [**])  prior  to  making  such  payment  and  will  cooperate  with  the  payee  as
provided  in  this  Section   9.11.5  (Taxes)  in  order  to  mitigate  the  imposition  of  such  Withholding  Taxes.    Notwithstanding  the
foregoing, if the recipient Party is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, or recovery
of, applicable Withholding Tax, it may deliver to the payor Party or the appropriate Governmental Authority the prescribed forms
necessary to reduce the applicable rate of withholding or to relieve the payor Party of its obligation to withhold Tax.  In such case
the payor Party will apply the reduced rate of withholding, or not withhold, as the case may be, provided that the payor Party is in
receipt  of  evidence,  in  a  form  reasonably  satisfactory  to  the  payor  Party  of  the  recipient  Party’s  entitlement  to  a  reduced  or  no
withholding rate at least [**] prior to the time that the applicable Payment is due.  If a payor Party withholds any amount, it will pay
to the recipient Party the balance (for the avoidance of doubt, net of the withholding) when due, make timely payment to the proper
taxing  authority  of  the  withheld  amount,  and  send  the  recipient  Party  proof  of  such  payment  within  [**]  following  that
payment.    The  Parties  will  reasonably  cooperate  to  reduce  or  eliminate  any  withholding  required  under  applicable  Law,  and  to
provide the other with reasonable assistance to enable the recovery, as permitted by Law, of Withholding Taxes, with recovery to be
for the benefit of the payee Party.  Sage will provide a complete and accurate IRS Form W-9 to Biogen prior to payment of the due
date of the Upfront Payment and will promptly

80

 
 
provide a new properly executed IRS Form W-9 if information provided on the previous IRS Form W-9 changes or if an updated
IRS Form W-9 or its equivalent is required by law or requested by Biogen.  Based on the foregoing, the Parties acknowledge and
agree that, as of the date hereof, no Withholding Taxes (other than with respect to the Federal Republic of Germany) are expected to
be deducted or withheld from any Payments.

9.11.5.2

VAT.    It  is  understood  and  agreed  between  the  Parties  that  any  payments  made  under  this
Agreement are exclusive of VAT. Where VAT is properly added to a payment made under this Agreement, the payor Party will pay
the amount of such VAT only on receipt of a valid Tax invoice (or, where there is no provision in the legislation for the jurisdiction
concerned  that  a  VAT  invoice  is  required  to  be  issued,  a  written  demand  containing  such  information  as  is  customary  in  that
jurisdiction) issued in accordance with the Laws and regulations of the country in which the VAT is chargeable. If in the event of
any amendment to VAT Laws the sums invoiced without VAT in accordance with this Agreement become or are subject to VAT,
then the applicable invoices will be deemed to be exclusive of VAT and the payor Party will, in addition to the sums payable, pay
the  recipient  Party,  on  receipt  of  an  updated,  valid  VAT  invoice,  the  full  amount  of  VAT  chargeable  thereon.    The  Parties
acknowledge and agree that, as at the date of this Agreement, no VAT is expected to be charged by Sage on amounts payable by
Biogen pursuant to this Agreement, as Sage is not required to account for VAT as at the date of this Agreement in relation to the
services, rights and licenses provided by Sage to Biogen pursuant to this Agreement.  Notwithstanding anything in this Agreement
to the contrary, Sage agrees that prior to establishing a taxable presence for VAT outside the United States of America, assigning,
delegating,  sublicensing  or  otherwise  transferring  (to  include  by  merger)  its  rights  or  obligations  under  this  Agreement  to  an
assignee, delegate, sublicensee or other transferee (including by operation of a merger) which would require a charge to VAT (other
than  VAT  chargeable  by  a  Government  Authority  of  the  United  States  of  America)  on  amounts  payable  by  Biogen  under  this
Agreement  (either  singly  or  together  referred  to  as  a  “VAT  Restructuring”),  Sage  will:  (a)  consult  with  Biogen;  and  (b)  take
account of reasonable representations made by Biogen where Biogen is able to demonstrate to Sage’s reasonable satisfaction that
Sage’s  proposed  assignee,  delegate,  sublicensee  or  other  transferee  would  give  rise  to  irrecoverable  VAT  costs  for  Biogen  which
would not otherwise exist in the absence of any act, default, omission or transaction involving Biogen.

9.11.5.3

Tax  Actions.    Notwithstanding  anything  in  this  Agreement  to  the  contrary,  if  an  action
(including but not limited to a VAT Restructuring, any assignment, delegation or sublicense of a Party’s rights or obligations under
this Agreement (including a subsequent transfer following such assignment, delegation or sublicense), a change or adoption of a Tax
reporting position, a change in the corporate or tax status or location of a Party, or any failure to comply with applicable Laws or
filing or record retention requirements) by a Party (a “Tax Action”) leads to the imposition or incidence of any Withholding Tax
liability or VAT on the other Party that would not have been imposed in the absence of such Tax Action or in an increase in such
liability  above  the  liability  that  would  have  been  imposed  in  the  absence  of  such  Tax  Action  (such  additional  or  increased
Withholding Tax liability or VAT, “Incremental Taxes”), such Party will indemnify and hold harmless the other Party (the “Non-
Acting Party”) from any such Incremental Taxes (except to the extent that the other Party can reclaim or otherwise offset or recover
such Incremental Taxes, provided that such other Party will be reimbursed for any reasonable out of pocket costs incurred in the
reclaim).    The  indemnification  obligation  described  in  the  preceding  sentence  shall  not  apply,  however,  to  the  extent  such
Incremental Taxes (a) would not have been imposed but for a prior Tax Action taken by the Non-Acting Party or (b) are attributable
to a the failure of the Non-Acting Party to comply with the requirements of this Section  9.11.5 (Taxes).

9.11.6

Payment Allocation.

81

 
 
9.11.6.1

Subject  to  the  remainder  of  this  Section  9.11.6  (Payment  Allocation),  payments  under  this
Agreement  will  be  paid  by  BIMA  and  BIG  separately  and  in  such  proportions  as  determined  solely  by  Biogen  in  its  reasonable
discretion  and  shall  be  invoiced  separately  by  Sage;  provided  that  separate  invoices  will  only  be  provided  by  Sage  if  Biogen
provides  details  of  the  allocations  of  such  amounts  between  BIMA  and  BIG  in  writing  and  reasonably  in  advance  of  each  such
payment becoming due and failure to provide such invoices will not affect Biogen’s obligations to make any such payments as and
when due.

9.11.6.2

With  respect  to  the  upfront  payment  described  in  Section  9.1  (Upfront  Fee),  BIG  will  pay  a
portion of such amount in consideration of the rights granted outside of the United States which will equal [**] Dollars ($[**]), and
BIMA will pay a portion of such amount in consideration of the rights granted in the United States which will equal [**] Dollars
($[**]).

9.11.6.3

the  324  Regulatory/Commercial  Milestone  Payments 

With  respect  to  the  payments  for  the  217  Regulatory/Commercial  Milestone  Payments  in
in  Section  9.6.2  (Licensed  324  Products
Section  9.6.1  and 
Regulatory/Commercial Milestones), BIG will pay a percentage of each such amount in consideration of the rights granted outside
of the United States and BIMA will pay a percentage each such amount in consideration to the rights granted in the United States,
such  percentages,  in  each  case,  to  be  determined  by  Biogen  at  the  time  at  which  such  amounts  are  due.  Notwithstanding  the
foregoing, [**].

9.11.6.4

With  respect  to  the  217  Sales  Milestone  Payments  in  Section  9.7.1  (Licensed  217  Products
Sales Milestones) and 324 Sales Milestone Payments in and Section 9.7.2 (Licensed 324 Products Sales Milestones), BIG will pay a
percentage of each such amount in consideration of the rights granted outside of the United States, and BIMA will pay a percentage
of each such amount in consideration to the rights granted in the United States, such percentages, in each case, to be determined by
Biogen at the time at which such amounts are due.

9.11.6.5

With  respect  to  Biogen  Territory  Royalties  and  the  Territory  Royalties,  BIG  will  pay  such
Biogen Territory Royalties described in Section 9.8.1 (Biogen Territory Royalties), and in the event that Sage has exercised an Opt-
Out  Right  with  respect  to  either  or  both  of  the  Product  Classes  for  the  Licensed  217  Products  or  the  Licensed  324  Products,  as
applicable, then from and after the Opt-Out Date for the applicable Product Class, during the remainder of the Royalty Term for
each  Licensed  217  Product  or  each  Licensed  324  Product  in  the  Product  Class(es)  for  which  Sage  exercised  the  Opt-Out  Right,
BIMA will pay such United States Royalties described in Section 9.8.2 (United States Royalties).

9.11.6.6

With  respect  to  all  payments  set  forth  in  this  Article  9  (Payments)  that  are  not  described  in
Section  9.11.6.2  (Payment  Allocation)  through  Section  9.11.6.5  (Payment  Allocation)  above,  BIG  will  pay  such  amount  in
consideration  of  the  rights  granted  outside  of  the  United  States  and  BIMA  will  pay  such  amount  in  consideration  to  the  rights
granted in the United States, such percentages, in each case, to be determined by Biogen at the time in which such amounts are due.

(Coordination between BIMA and BIG) of this Agreement.

9.11.6.7

For  clarity,  nothing  in  this  Section  9.11  (Payment  Terms)  is  intended  to  limit  Section  15.15

9.11.7

Blocked Payments.  In the event that, by reason of applicable Law in any country, it becomes impossible or
illegal for the Paying Party to transfer, or have transferred on its behalf, payments owed by the Paying Party to the other Party hereunder, the
Paying  Party  will  promptly  notify  the  other  Party  of  the  conditions  preventing  such  transfer  and  such  payments  will  be  deposited  in  local
currency in the

82

 
 
relevant country to the credit of the other Party in a recognized banking institution designated by the other Party or, if none is designated by the
other Party within a period of [**], in a recognized banking institution selected by the Paying Party, as the case may be, and identified in a
written notice given to the other Party.

9.11.8

Right  of  Offset.    Upon  notice  to  the  other  Party,  each  Party  will  have  the  right  to  offset  any  undisputed
Payment not paid within the specified period owed by such Party to the other Party under this Agreement, including in connection with any
breach  or  indemnification  obligation  by  such  Party,  against  any  undisputed  Payments  owed  by  the  other  Party  to  such  Party  under  this
Agreement.  Such  offsets  will  be  in  addition  to  any  other  rights  or  remedies  available  to  the  offsetting  Party  under  this  Agreement  and
applicable Laws.

Interest Due.  The Paying Party will pay the other Party interest on any undisputed payments that are not
paid on or before the date such payments are due under this Agreement at a rate equal to [**] percentage points ([**]%) per annum or, if lower,

10.1

Nondisclosure and Non-Use Obligations.

10.1.1

All  Confidential  Information  disclosed  by  one  Party  (the  “Disclosing  Party”)  to  the  other  Party  (the
“Receiving Party”) under this Agreement will be maintained in confidence by the Receiving Party and will not be disclosed to a Third Party or
used for any purpose except pursuant to the licenses granted under this Agreement or as otherwise set forth herein, without the prior written
consent of the Disclosing Party. Notwithstanding any provision to the contrary set forth in this Agreement, Confidential Information will not
include any information that:

(a)

(b)

(c)

(d)

is known by the Receiving Party at the time of its receipt from the Disclosing Party, and not through a prior
disclosure by the Disclosing Party, as documented by the Receiving Party’s business records;

is known to the public before its receipt from the Disclosing Party, or thereafter becomes generally known to
the public through no breach of this Agreement by the Receiving Party;

is subsequently disclosed to the Receiving Party by a Third Party who is not known by the Receiving Party to
be under an obligation of confidentiality to the Disclosing Party; or

is developed by the Receiving Party independently of Confidential Information received from the Disclosing
Party, as documented by the Receiving Party’s business records.

For clarity, and notwithstanding any provision to the contrary set forth in this Agreement, [**].  Specific aspects
or details of Confidential Information will not be deemed to be within the public domain or in the possession of the Receiving Party
merely because the Confidential Information is encompassed by more general information in the public domain or in the possession
of the Receiving Party.  Further, any combination of Confidential Information will not be considered in the public domain or in the
possession of the Receiving Party merely because individual elements of such Confidential Information are in the public domain or
in the possession

83

 
 
 
 
 
 
of the Receiving Party unless the combination and its principles are in the public domain or in the possession of the Receiving Party.

Party.

The  terms  and  conditions  of  this  Agreement  are  hereby  deemed  to  be  the  Confidential  Information  of  each

10.1.2

Permitted Disclosures.  Notwithstanding the obligations of confidentiality and non-use set forth in Section
10.1.1 (Nondisclosure and Non-Use Obligations) above, a Receiving Party may provide Confidential Information disclosed to it and disclose
the existence and terms and conditions of this Agreement, in each case, as may be reasonably required in order to perform its obligations or to
exercise its rights under this Agreement, and to the extent such disclosure is:

10.1.2.1

to its Affiliates, Sublicensees or licensees, and their employees, directors, agents, consultants,
or  advisors  to  the  extent  necessary  for  the  potential  or  actual  performance  of  its  obligations  or  exercise  of  its  rights  under  this
Agreement, in each case, who are under an obligation of confidentiality with respect to such information that is no less stringent
than the terms and conditions of this Section 10.1 (Nondisclosure and Non-Use Obligations);

to  the  Regulatory  Authorities  in  connection  with  any  filing,  application  or  request  for
Regulatory Approval in accordance with the terms of this Agreement; provided that reasonable measures shall be taken to assure
confidential treatment of such Confidential Information to the extent practicable and consistent with applicable Law;

10.1.2.2

made  in  connection  with  the  Prosecution  and  Maintenance  of  Sage  Licensed  Technology  or
Biogen Licensed Technology in an effort to secure, maintain, defend or enforce Patents, as contemplated by this Agreement, or, with
respect to such activities only, otherwise with the prior written consent of the disclosing Party’s intellectual property counsel;

10.1.2.3

10.1.2.4
rights and obligations pursuant to this Agreement;

to  bring  or  defend  litigation  and  to  enforce  Patents  in  connection  with  the  Receiving  Party’s

subject to Section 10.1.2.8 (Permitted Disclosures), required to be disclosed by applicable Law,
including by the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a
country other than the United States or of any stock exchange or listing entity;

10.1.2.5

10.1.2.6

(a)  with  respect  to  the  terms  and  conditions  of  this  Agreement,  any  bona  fide  actual  or
prospective  acquirers,  underwriters,  investors,  lenders,  other  financing  sources,  licensors,  Sublicensees  or  licensees  and  to
employees, directors, agents, consultants or advisors of such Third Party, and (b) with respect to any other Confidential Information
of the other Party, any bona fide actual or prospective acquirers, licensors, Sublicensees or licensees and to employees, directors,
agents, consultants or advisors of such Third Party, provided that any entity or individual receiving Confidential Information under
clause (a) or (b) has a need to know such information and is under obligations of confidentiality and non-use with respect to such
information that are no less stringent than the terms and conditions of this Section 10.1 (Nondisclosure and Non-Use Obligations)
(but of duration customary in confidentiality agreements entered into for a similar purpose); and

to any Third Party to the extent a Party is required to do so pursuant to the terms and conditions
of  an  in-license  agreement  with  such  Third  Party  relating  to  the  intellectual  property  rights  sublicensed  to  such  Party  hereunder,
provided that any such Third Party receiving

10.1.2.7

84

 
 
Confidential  Information  is  under  obligations  of  confidentiality  and  non-use  with  respect  to  such  information  that  are  no  less
stringent than the terms and conditions of this Section 10.1 (Nondisclosure and Non-Use Obligations).  

10.1.2.8

if  a  Party,  after  consultation  with  counsel,  determines  it  is  required  by  Law  to  disclose
Confidential  Information  of  the  other  Party  that  is  subject  to  the  confidentiality  or  non-disclosure  provisions  of  this  Section  10.1
(Nondisclosure  and  Non-Use  Obligations),  then  such  Party  will  promptly  inform  the  other  Party  of  the  disclosure  that  is  being
sought (and to the extent possible at least [**] notice) in order to provide the other Party an opportunity to challenge or limit the
disclosure and will reasonably cooperate with the other Party to do so. In the event that no such protective order or other remedy is
obtained, or the Disclosing Party waives compliance with certain terms of this Article 10 (Confidentiality And Publication), then the
Receiving Party will furnish only that portion of Confidential Information that the Receiving Party is advised by counsel is legally
required to be disclosed. Notwithstanding Section  10.1.1 (Nondisclosure and Non-Use Obligations), Confidential Information that is
permitted or required to be disclosed will remain otherwise subject to the confidentiality and non-use provisions of this Section 10.1
(Nondisclosure and Non-Use Obligations).  If either Party concludes based on the reasonable opinion of counsel that a copy of this
Agreement  must  be  filed  with  the  United  States  Securities  and  Exchange  Commission  or  similar  regulatory  agency  in  a  country
other than the United States, such Party will, within a reasonable time prior to any such filing (and to the extent possible at least [**]
prior to any such filing), provide the other Party with a copy of this Agreement showing any provisions hereof as to which the Party
proposes  to  request  confidential  treatment,  will  provide  the  other  Party  with  an  opportunity  to  comment  on  any  such  proposed
redactions and to suggest additional redactions, and will take such Party’s reasonable comments into consideration before filing such
copy of this Agreement and use reasonable efforts to have terms identified by such other Party afforded confidential treatment by
the applicable regulatory agency.

10.2

Publication and Publicity.

10.2.1

Publication.    [**].    Each  Party  via  the  Joint  Publications  Working  Group  will  have  the  right  to  propose
additions or other amendments to an existing Publications Plan for approval by the JSC.  The Joint Publications Working Group will determine
which  of  Sage  or  Biogen  will  have  the  first  right  (but  not  the  obligation)  to  be  responsible  for  each  Joint  Publication  contemplated  in  each
Publication  Plan  (such  appointed  Party,  the  “Lead  Publishing  Party”);  provided,  however,  that,  unless  otherwise  agreed  by  the  Joint
Publications  Working  Group  in  the  Publications  Plan,  Sage  will  be  the  Lead  Publishing  Party  for  all  Joint  Publications  contemplated  in  the
applicable Publications Plan related to the Ongoing 217 Studies or the KINETIC Study.  Upon Biogen becoming the Regulatory Lead Party
with  respect  to  the  applicable  Product  Class,  the  Joint  Publications  Working  Group  will  determine  which  of  the  Parties  will  be  the  Lead
Publishing  Party  with  respect  to  Joint  Publications,  including  those  related  to  the  Ongoing  217  Studies  or  the  KINETIC  Study,  as
applicable.  In the event that the Lead Publishing Party elects not to exercise such right with respect to a certain Publication, the responsibility
for such Publication will pass to the other Party. [**].

10.2.2

Right to Review.  Each Party will have the right to review any Publication that contains results arising from
the  performance  of  Development,  Commercialization  or  Medical  Affairs  Activities  with  respect  to  any  Licensed  Product  or  that  includes
Confidential  Information  of  the  non-publishing  Party.  The  publishing  Party  will  provide  the  other  non-publishing  Party  the  opportunity  to
review such proposed Publication at least [**] prior to the earlier of its intended submission for publication or publication, and the publishing
Party will consider in good faith any reasonable and timely comments submitted by the non-publishing Party (it being understood and agreed
that if there is a material amendment to such Publication after the publishing Party has provided such Publication to the non-publishing Party,

85

 
 
such reviewing period will be extended to ensure that at least [**] remain for the non-publishing Party to review subsequent to the date the
non-publishing Party received the amended Publication).  Further, the non-publishing Party will have the right (a) to propose modifications to
the Publication to remove Confidential Information solely of such non-publishing Party, in which case the publishing Party will remove such
Confidential  Information  solely  of  the  non-publishing  Party  identified  by  the  non-publishing  Party,  or  (b)  to  request  a  reasonable  delay  in
Publication in order to protect patentable information, in which case the publishing Party will delay submission for a period of [**] (or such
other period as may be mutually agreed by the Parties in writing) to enable the non-publishing Party to file Patent applications protecting the
non-publishing  Party’s  rights  in  such  information.    The  publishing  Party  subsequently  will  provide  the  non-publishing  Party  a  copy  of  the
Publication at the time of its submission.  Without limiting the foregoing, each publishing Party agrees to acknowledge the contributions of the
other  Party  and  the  employees  of  the  other  Party,  in  all  Publications,  as  scientifically  appropriate.  After  the  release  of  any  Publication  by  a
Party  in  accordance  with  this  Section  10.2  (Publication  and  Publicity),  such  Party  may  further  disclose  the  information  contained  in  such
Publication  without  the  need  for  further  notice  to,  or  review  by,  the  other  Party  under  this  Section  10.2.2  (Publication  and  Publicity)  or
otherwise.  In the event of any dispute between the Parties with respect to the contents of any Joint Publication or any Biogen Publication, the
Parties will submit such dispute to the Joint Publications Working Group to determine resolution.

10.2.3

Publicity.  Except as set forth in Section 10.1 (Nondisclosure  and  Non-Use  Obligations),   Section  10.2.1
(Publication) or Section 10.3 (Press Release, Public Announcements and Other Public Disclosure) and in this Section 10.2.3  (Publicity),  the
terms and conditions of this Agreement may not be disclosed by either Party, and neither Party will use the name or Trademark of the other
Party or its employees in any publicity, news release or other disclosure relating to this Agreement, its subject matter, or the activities of the
Parties under this Agreement without the prior express written permission of the other Party, provided that the Party making such disclosure or
use  of  the  name  or  Trademark  of  the  other  Party  or  its  employees,  not  covered  by  Section 10.1  (Nondisclosure  and  Non-Use  Obligations),
 Section 10.2.1 (Publication) or Section 10.3  (Press  Release,  Public  Announcements  and  Other  Public  Disclosure)  and  in  this  Section  10.2.3
(Publicity), obtains the prior consent (not to be unreasonably withheld, conditioned or delayed) of such other Party if such disclosure references
such other Party and otherwise complies with Section 10.1 (Nondisclosure and Non-Use Obligations) or (b) as expressly permitted by the terms
and conditions hereof.  Notwithstanding the foregoing, either Party may disclose information (a) that has already been made public through a
press release, publication or other public statement made in accordance with the terms of this Agreement so long as such information remains
true,  correct  and  current,  or  (b)  in  connection  with  disclosures  under  a  joint  communication  plan  agreed  upon  by  the  Parties.    The  Parties,
through their respective heads of Corporate Communications and Investor Relations, will agree on procedures to operationalize the provisions
of Section 10.3 (Press Release, Public Announcements and Other Public Disclosure) and in this Section 10.2.3 (Publicity).

10.3

Press Release, Public Announcements and Other Public Disclosure.

Schedule  10.3.1 (Press Release).

10.3.1

On the Execution Date, the Parties will issue the joint press release substantially in the form attached as in

10.3.2

Except  as  provided  in  Section  10.2.3  (Publicity)  or  this  Section 10.3  (Press  Release),  neither  Party  will
issue a press release, public announcement or other public disclosure relating to this Agreement or the Parties’ activities hereunder without the
prior  written  approval  of  the  other  Party  (such  approval  not  to  be  unreasonably  withheld,  conditioned  or  delayed),  except  that  a  Party  may
(a)  once  a  press  release,  public  statement  or  other  public  statement  has  been  made  as  permitted  under  the  terms  of  this  Agreement,  make
subsequent  public  disclosure  of  the  information  contained  in  such  press  release,  publication  or  other  public  statement  so  long  as  such
information remains true, correct and current, (b) make a disclosure expressly permitted in accordance with this Article 10 (Confidentiality and
Publication), and

86

 
 
(c) make any such other disclosure that is, in the opinion of the Receiving Party’s counsel, required by applicable Law, including by the rules or
regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States or
of any stock exchange or listing entity on which securities of the Receiving Party are listed, provided that, solely with respect to clause (c), the
Party issuing such press release, public announcement or other public disclosure gives reasonable prior written notice to the other Party of and
the opportunity to comment on such press release, public announcement or other public disclosure will submit the same in writing to the other
Party as far in advance as reasonably practicable (and in no event less than [**] prior to the anticipated date of disclosure, unless such proposed
disclosure is required under applicable Law or the rules of an applicable securities exchange, in each case, to be made in less than [**]) so as to
provide the Disclosing Party a reasonable opportunity to comment thereon.

the Effective Date to the extent arising out of or resulting from (a) any breach of this Agreement, including any breach of a representation or
warranty made by Biogen in this Agreement, or any breach or violation of any covenant or agreement of Biogen in this Agreement, (b) the
gross negligence, reckless conduct or willful misconduct by or on the part of Biogen or any of its Affiliates, or any of their respective directors,
officers, employees or agents in the performance of Biogen’s or their obligations under this Agreement, or (c) the Development, Manufacture,
performance of Medical Affairs Activities with respect to or Commercialization of Licensed Products by or on behalf of Biogen or any of its
Related  Parties  in  the  Biogen  Territory  pursuant  to  this  Agreement.    Notwithstanding  the  foregoing,  Biogen  will  have  no  obligation  to
indemnify  any  of  the  Sage  Indemnitees  to  the  extent  that  any  Losses  arise  out  of  or  result  from  any  matters  for  which  Sage  is  obligated  to
indemnify the Biogen Indemnitees under Section 12.2 (General Indemnification by Sage).

93

 
 
12.2

General Indemnification by Sage.  Sage will indemnify, hold harmless, and defend each of Biogen, its Related Parties
and  their  respective  directors,  officers,  employees  and  agents  (“Biogen  Indemnitees”)  from  and  against  any  and  all  Losses  incurred  in
connection with Third Party Claims incurred by or rendered against the Biogen Indemnitees after the Effective Date to the extent arising out of
or resulting from (a) any breach of this Agreement, including any breach of a representation or warranty made by Sage in this Agreement, or
any  breach  or  violation  of  any  covenant  or  agreement  of  Sage  in  this  Agreement,  (b)  the  gross  negligence,  reckless  conduct  or  willful
misconduct  by  or  on  the  part  of  Sage  or  any  of  its  Affiliates,  or  any  of  and  their  respective  directors,  officers,  employees  or  agents  in  the
performance of Sage’s obligations under this Agreement, (c) the Development, Manufacture, performance of Medical Affairs Activities with
respect to or Commercialization of Licensed 217 Products in the Existing Partner Territory whether before, after or during the Term, (d) the
Development, Manufacture or Commercialization by or on behalf of Sage or any of its Related Parties (excluding such conduct by or on behalf

before or after the Term, or (e) the conduct of the [**] by or on behalf of Sage or any of its Related Parties.  Notwithstanding the foregoing,
Sage will have no obligation to indemnify any of the Biogen Indemnitees to the extent that any Losses arise out of or result from, directly or

Biogen).

12.3

Indemnification Procedure.  Each Party will notify the other Party in writing in the event it becomes aware of a Third
Party  Claim  for  which  indemnification  may  be  sought  hereunder.  The  Party  entitled  to  indemnification  under  Section  12.1  (General
Indemnification by Biogen) or 12.2 (General Indemnification by Sage) (an “Indemnified Party”) will notify the Party potentially responsible
for  such  indemnification  (the  “Indemnifying Party”)  in  writing  promptly  upon  being  notified  of  or  having  knowledge  of  any  Third  Party
Claim asserted or threatened against the Indemnified Party that could give rise to a right of indemnification under this Agreement; provided
that the failure to give such notice will not relieve the Indemnifying Party of its indemnity obligation hereunder except to the extent that such
failure materially prejudices the Indemnifying Party.  The Indemnifying Party and the Indemnified Party will meet to discuss how to respond to
any Third Party Claim.  The Indemnified Party will cooperate fully with the Indemnifying Party in defense of such Third Party Claim.  In any
such proceeding, the Indemnified Party will have the right to retain its own counsel, but the fees and expenses of such counsel will be at the
expense of the Indemnified Party unless (a) the Indemnifying Party and the Indemnified Party will have agreed to the retention of such counsel
or (b) the named parties to any such proceeding (including any impleaded parties) include both the Indemnifying Party and the Indemnified
Party  and  representation  of  both  Parties  by  the  same  counsel  would  be  inappropriate  due  to  actual  or  potential  differing  interests  between
them.    All  such  fees  and  expenses  of  the  Indemnified  Party  by  application  of  the  foregoing  clause  (a)  or  (b)  will  be  reimbursed  by  the
Indemnifying Party as they are incurred.  The Indemnifying Party will not be liable for any settlement of any proceeding effected without its
written consent, but, if settled with such consent or if there is a final judgment for the Third Party plaintiff, then the Indemnifying Party agrees
to indemnify the Indemnified Party from and against any Losses by reason of such settlement or judgment. The Indemnifying Party will not,
without  the  written  consent  of  the  Indemnified  Party  (such  consent  not  to  be  unreasonably  withheld,  conditioned  or  delayed),  effect  any
settlement of any pending or threatened proceeding in respect of which the Indemnified Party is, or could have been, a party and indemnity
could have been sought hereunder by the Indemnified Party, unless such settlement includes an unconditional release of the Indemnified Party
from all liability on claims that are the subject matter of such proceeding.

12.4

Certain Third Party Claims Related to Licensed Products in the Profit-Share Territory.  If either Party receives
notice of a Third Party Claim that is incurred from or is based on any Joint Program Activities, then such Party will inform the other Party in
writing as soon as reasonably practicable, and the Parties will discuss a strategy on how to, and which Party will, defend against such Third
Party Claim.  Any Losses as they are incurred in connection with any such Third Party Claim, as well

94

Prosecuted Patent or [**] Collaboration Patent in the Territory, then [**] will so notify the IP Committee in writing, and, so long as
[**] election not to take any such action is not due to [**] (“Strategic Enforcement or Defense Reasons”), following discussion of

at  its  sole  cost  and  expense,  will  have  the  right  (but  not  the  obligation)  to  exercise  the  rights  set  forth  in  Section  13.5.5.1
(Withdrawal, Cooperation and Participation) and become the Defending Party with respect to enforcing any [**] Prosecuted Patent
or  [**]  Collaboration  Patent,  as  applicable,  to  abate  such  Competitive  Infringement  of  a  Licensed  Product  in  the  Profit-Share
Territory; provided that, if [**], then the Parties will share equally all Patent Costs incurred by [**] to abate any such Competitive
Infringement of such Licensed Product in the Profit-Share Territory.  For the avoidance of doubt, and notwithstanding anything in
this Agreement to the contrary, [**] will have the sole and exclusive right (but not the obligation), at [**] sole discretion, to enforce
any [**] Background Patent against a Competitive Infringement.

13.5.2.2

35 U.S.C. § 271(e)(2) Infringement.  Notwithstanding anything to the contrary in this Section
13.5.2 (Rights to Enforce), for a Competitive Infringement under 35 U.S.C. § 271(e)(2), or its equivalent in a country other than the

of [**] decision as to whether to take any action with respect to such Competitive Infringement so that [**] may have the right,
pursuant to such Section 13.5.2.1 (In the Territory), to initiate a Proceeding if [**] does not elect to initiate a Proceeding.

13.5.2.3

Notification of Patent Certification.  If either Party becomes aware of any allegations of alleged
patent invalidity, unenforceability or non-infringement of any Patent licensed under this Agreement Covering a Licensed Product
(including methods of use thereof) pursuant to a Paragraph IV Patent Certification by a Third Party filing an Abbreviated New Drug
Application, or other similar patent certification by a Third Party, and any foreign equivalent thereof, for a Generic Product, then
such Party will notify and provide the other Party with copies of such allegations.  Such notification and copies will be provided to
such other Party as soon as practicable and at least within [**] after such Party receives such certification, and will be sent by email
and overnight courier to the address set forth in Section 15.10 (Notices).

13.5.3

conduct any Post-Grant Proceedings with respect to any [**] Prosecuted Patent; provided that, if [**], then the Parties will share equally all
Patent  Costs  incurred  by  [**]  in  connection  with  the  defense  of  such  Third  Party  Action  or  Post-Grant  Proceeding.    Within  [**]  after  the
relevant personnel at either Party receiving notice of a Third Party Action or becoming aware of the initiation of a Post-Grant Proceeding (or as
otherwise agreed by the IP Committee), such Party will notify the other Party, and within a reasonable time to meet for a discussion thereof, the
IP  Committee  will  meet  for  discussion  pursuant  to  Section 13.4.1.3(c)  (IP  Committee  Responsibilities).    Thereafter,  [**]  will  notify  the  IP
Committee  of  its  intent  to  defend  such  Patent  or  conduct  any  Post-Grant  Proceeding  under  this  Section  13.5.3  (Defense  and  Post-Grant
Proceedings), as applicable, within [**] (or as otherwise agreed by the IP Committee) after such IP Committee meeting (or such shorter period
of time as is required to comply with applicable Law in the Territory to not waive any statutory rights).  If [**] does not provide notice to the IP
Committee  of  [**]  intent  to  defend  such  Patent  or  conduct  any  Post-Grant  Proceeding  under  this  Section  13.5.3  (Defense  and  Post-Grant
Proceedings),  as  applicable,  within  [**]  after  such  IP  Committee  meeting  (or  such  shorter  period  of  time  as  is  required  to  comply  with
applicable Law in the Territory to not waive any statutory rights), or

101

 
 
elects not to initiate or continue any such defense or Post-Grant Proceeding (in which case it will promptly provide notice thereof to [**]) then,
as  long  as  [**]  decision  not  to  take  any  such  action  is  not  due  to  Strategic  Enforcement  or  Defense  Reasons,  [**]  will,  upon  receiving
confirmation from [**] that [**] has not taken any such action within the applicable period set forth in this Section 13.5.3 (Defense and Post-
Grant Proceedings), have the right (but not the obligation), at its sole cost and expense, as the new Defending Party, at its sole discretion, to
defend any such Patent against such a Third Party Action or conduct Post-Grant Proceedings for such Patent, as applicable, in each case of (a)
and (b), as further set forth in Section 13.5.5 (Withdrawal, Cooperation and Participation); provided that, if [**], the Parties will share equally
all Patent Costs incurred by [**] in connection with the defense of such Third Party Action or such Post-Grant Proceeding.  For the avoidance
of doubt, and notwithstanding anything in this Agreement to the contrary, [**] will have the sole and exclusive right (but not the obligation), at
[**] sole discretion, to defend any [**] Background Patent against a Third Party Action.

13.5.4

Cooperation  Regarding  Enforcement,  Defense  or  Post-Grant  Proceedings.    With  respect  to  any
Competitive  Infringement  action,  Third  Party  Action  or  Post-Grant  Proceeding  identified  above  in  Section  13.5.2  (Right  to  Enforce)  and
Section 13.5.3 (Defense and Post-Grant Proceedings) and subject to the terms and conditions of this Section 13.5.4  (Cooperation  Regarding
Enforcement, or Defense or Post-Grant Proceedings), the Party controlling any such Competitive Infringement action, Third Party Action or
Post-Grant Proceeding (the “Defending Party”) will keep the other Party (the “Non-Defending Party”) reasonably informed of the status and
progress of such enforcement, defense or Post-Grant Proceeding strategy via the IP Committee.  The Defending Party will reasonably consider
the  Non-Defending  Party’s  comments  on  any  such  efforts.   The  Non-Defending  Party  will  provide  the  Defending  Party  with  all  reasonable
assistance  in  the  enforcement  or  defense  of  the  applicable  Patents,  as  the  Defending  Party  may  request,  at  such  Defending  Party’s  expense,
including by signing or executing any necessary documents and consenting to it being named a party to any applicable proceedings.  Where the
Non-Defending Party is named a party or otherwise is joined involuntarily in any applicable proceeding, the Non-Defending Party will have
the right to be represented by counsel of its choice at the Defending Party’s expense, provided that in all other cases the Non-Defending Party
will be solely responsible for the costs and expenses of its counsel and in all instances all communications between the Non-Defending Party
and the Defending Party will be subject to the principles of Section 13.9 (Common Interest).

Withdrawal, Cooperation and Participation.  With respect to any Competitive Infringement action, Third
Party Action or Post-Grant Proceeding identified above, respectively, in Section 13.5.2 (Rights to Enforce) and Section 13.5.3  (Defense  and
Post-Grant Proceedings) and subject to the terms and conditions of this Section 13.5.5 (Withdrawal, Cooperation and Participation):

13.5.5

13.5.5.1

If  [**]  ceases  to  pursue  or  withdraws  from  such  action,  it  will  promptly  notify  [**]  (in
sufficient time to enable [**] to meet any deadlines by which any action must be taken to preserve any rights in such infringement,
defensive action or Post-Grant Proceeding), then [**] will have the right (but not the obligation) to substitute itself for [**] in any
Competitive  Infringement  action  identified  above  in  Section 13.5.2.2  (35  U.S.C.  §  271(e)(2)  Infringement)  or  in  any  Third  Party
Action or Post-Grant Proceeding identified above in Section 13.5.3 (Defense and Post-Grant Proceedings), in each case, involving
any  [**]  Prosecuted  Patents  or  [**]  Collaboration  Patents  and  proceed  under  the  terms  and  conditions  of  this  Section  13.5.5
(Withdrawal, Cooperation and Participation).

13.5.5.2

[**] will cooperate with [**] in controlling any such action (as may be reasonably requested by
[**]), including, at [**] sole cost and expense, (a) providing access to relevant documents and other evidence, (b) using reasonable
efforts  to  make  [**]  Affiliates  and  its  and  its  Affiliates’  licensees  and  Sublicensees  and  all  of  their  respective  employees,
subcontractors, consultants and agents available at reasonable business hours and for reasonable periods of time,

102

 
 
but only to the extent relevant to such action, and (c) if reasonably necessary, by being joined as a party, subject to (with respect to
this clause (c)) [**] agreeing to indemnify [**] for its involvement as a named party in such action and paying those Patent Costs
incurred by [**] in connection with such joinder.  [**], as the Defending Party in any such action, will keep [**] reasonably updated
via  the  IP  Committee  with  respect  to  any  such  action,  including  providing  copies  of  all  materials  documents  received  or  filed  in
connection with any such action to the extent permitted by applicable Law.

13.5.5.3

[**]  will  have  the  right  to  consult  with  [**]  regarding  any  such  action  for  which  [**]  is  the
Defending Party via the IP Committee, in each case at [**] sole cost and expense.  If [**] elects to so be involved, [**] will provide
[**]  and  its  counsel  with  an  opportunity  to  consult  with  [**]  and  its  counsel  regarding  the  prosecution  of  such  action  (including
reviewing  the  contents  of  any  correspondence,  legal  papers  or  other  documents  related  thereto).  [**]  will  take  into  account
reasonable and timely requests and comments of [**] regarding such enforcement or defense.

13.5.6

Settlement.    With  respect  to  any  enforcement  action,  Third  Party  Action  or  Post-Grant  Proceeding
identified above in this Section 13.5 (Third Party Infringement and Defense and Post-Grant Proceedings), the Defending Party will have the
right  to  settle  or  otherwise  dispose  of  such  action  (a)  with  the  consent  of  the  other  Party,  if  it  involved  the  Profit-Share  Territory  and  (b)
otherwise, on such terms and conditions as such Defending Party will determine in its sole discretion; provided that, in either case ((a) or (b)),
notwithstanding the foregoing, no such settlement or other disposition will (i) impose any monetary restriction or obligation on or admit fault
of the other Party or (ii) adversely affect the other Party’s rights under this Agreement to any such Patent then being enforced or defended, in
each case ((i) and (ii) without the prior written consent of the other Party, not to be unreasonably withheld, conditioned or delayed).

13.5.7

Other  Invalidity  or  Unenforceability  Proceedings.    If  [**]  desires  to  bring  an  opposition,  action  for
declaratory  judgment,  nullity  action,  interference,  declaration  for  non-infringement,  reexamination,  post-grant  proceedings,  or  other  attack
upon the validity, title or enforceability of a Patent Right owned or controlled by a Third Party and having one (1) or more claims that Cover a
Licensed Product, or the use, sale, offer for sale or importation of a Licensed Product in the Territory, as applicable, (except insofar as such
action  is  a  counterclaim  to  or  defense  of,  or  accompanies  a  defense  of  a  Third  Party  Action  under  Section 13.5.3  (Defense  and  Post-Grant
Proceedings), in which case the provisions of such Section 13.5.3 (Defense and Post-Grant Proceedings) will govern), then [**] will so notify
[**] and the Parties will promptly confer through the IP Committee.  [**] will have the initial right, but not the obligation, to bring, at its own
expense and in its sole control, such action in the Territory.  [**] will be entitled to separate representation in such proceeding by counsel of its
own choice and at its own expense, and will cooperate fully with the Party so appointed.  Any awards or amounts received in bringing any such
action will be first allocated to reimburse [**]’s expenses in such action, and any remaining amounts will be allocated between the Parties in
accordance with the principle set forth in Section 13.5.8 (Allocation of Proceeds).

13.5.8

Allocation of Proceeds.  If either Party recovers monetary damages from any Third Party in a suit in the
Territory  pursuant  to  this  Section 13.5 (Third  Party  Infringement  and  Defense  and  Post-Grant  Proceedings)  or  any  royalties  from  a  license
agreement with a Third Party related to any alleged Competitive Infringement in the Territory, whether or not such damages or royalties result
from the infringement of [**] Prosecuted Patents or the [**] Prosecuted Patents, then such recovery will be allocated first to the reimbursement
of any expenses incurred by each Party in such litigation, action, or license, and any balance of any such recovery will be split as follows: (a) if
[**] brings the action, (i) treated as Net Revenues, to the extent relating to all Licensed Products in a Product Class in the Profit-Share Territory
prior to [**]’s exercise of an Opt-Out Right with respect to the applicable Product Class or (ii) as Net Sales, and shared with [**] as royalties
pursuant to Section 9.8 (Licensed 217 Product and Licensed 324 Product

103

 
 
Products Royalties), to the extent relating to all Licensed Products in a Product Class in the [**] Territory or after [**] has exercised an Opt-
Out Right with respect to the applicable Product Class; or (b) if [**] brings the action, then [**]% will be retained by [**] and [**]% will be
paid to [**].

13.6

Patent Extensions.  Subject to the rest of this Section 13.6 (Patent Extensions), with respect to any election to file for
patent term restoration or extension, or any of their equivalents, [**] will have the sole and exclusive right to make any such decision relating
to any [**] Prosecuted Patents or [**] Prosecuted Patents in the Territory with respect to any Licensed Product, provided that [**] will use
reasonable efforts to obtain any such patent term restoration or extension, or any of their equivalents available for the Patents subject to the
enforcement rights specified in Section 13.5.2 (Rights to Enforce) with respect to any Licensed Product; and further provided, however, that
[**] will not be required to use any such reasonable efforts in a manner inconsistent with any term or condition of this Section 13.6 (Patent
Extensions) if any such item could impair the applicable Patent (including its enforcement potential) or the ability to obtain any such patent
term restoration or extension, supplemental protection certificate or any of their equivalents for any other pharmaceutical product.  [**] will
consult with [**] through the IP Committee regarding the strategy for such filings.  Subject to Section 13.4.4 (Patent Costs Sharing), [**] will
bear all Patent Costs incurred in making such filings.  Upon the written request by [**], [**] will reasonably cooperate with the implementation
of such requesting Party’s decisions made in a manner consistent with this Section 13.6 (Patent Extensions).

13.7

Orange Book Listings.  [**] will have lead responsibility for making any filing with respect to any [**] Collaboration
Patent, Joint Collaboration Patent or [**] Licensed Patent in connection with the Orange Book maintained by the FDA or similar or equivalent
patent listing or linking requirement, if any, in other countries in the Territory for the Licensed Products.  [**] will consult with [**] through
the IP Committee regarding the strategy for such filings.  If the Parties disagree on the appropriate strategy with respect to any such filings, the
disagreement will be resolved by the IP Committee, subject to Section 13.4.1.4 (Decision Making).  [**] will provide reasonable assistance to
[**] in connection with any such filing.

13.8

Third Party Rights.  Notwithstanding the foregoing provisions of this Article 13 (Intellectual Property), each Party’s
rights  and  obligations  with  respect  to  any  Patent  under  this  Article  13  (Intellectual  Property)  will  be  subject  to  the  Third  Party  rights  and
obligations (including under any in-license of a Patent applicable to such Party’s licensed intellectual property rights hereunder) set forth in
Schedule 13.8 (Third Party Rights).

13.9

Common Interest.   All  information  exchanged  between  the  Parties  regarding  the  Prosecution  and  Maintenance,  and
enforcement  and  defense,  of  Patents  under  this  Article 13  (Intellectual  Property) will  be  deemed  Confidential  Information  of  the  disclosing
Party.  In addition, the Parties acknowledge and agree that, with regard to such Prosecution and Maintenance, and enforcement and defense, the
interests of the Parties as collaborators and licensor and licensee are to obtain the strongest patent protection possible, and as such, are aligned
and are legal in nature.  The Parties agree and acknowledge that they have not waived, and nothing in this Agreement constitutes a waiver of,
any legal privilege concerning the Patents under this Article 13 (Intellectual Property), including privilege under the common interest doctrine
and similar or related doctrines.  Notwithstanding anything to the contrary contained herein, to the extent a Party has a good faith belief that
any information required to be disclosed by such Party to the other Party under this Article 13 (Intellectual Property) is protected by attorney-
client privilege or any other applicable legal privilege or immunity, such Party will not be required to disclose such information and the Parties
will  in  good  faith  cooperate  to  agree  upon  a  procedure  (including  entering  into  a  specific  common  interest  agreement,  disclosing  such
information  on  a  “for  counsel  eyes  only”  basis  or  similar  procedure)  under  which  such  information  may  be  disclosed  without  waiving  or
breaching such privilege or immunity.

13.10

Trademarks.  In the Profit-Share Territory, (a) the JCC will recommend to the JSC to determine whether to approve a
designated  Commercialization  Lead  Party  to  be  responsible  for  implementing  the  LP  U.S.  TM  Strategy  for  the  registration,  maintenance,
enforcement  and  defense  of  the  LP  U.S.  Trademark  for  a  Licensed  Product,  which  Party  will  own  all  applications  for  registration  and
registrations for such LP U.S. Trademark, and (b) any and all Trademark Costs for the LP U.S. Trademarks incurred in accordance with the
applicable Joint Commercialization Plan and Joint Commercialization Budget will be deemed Joint Commercialization Costs. In the Biogen
Territory,  Biogen  will  be  responsible  for  the  registration,  maintenance,  enforcement  and  defense  of,  and  will  own  all  applications  for
registration and registrations for, all Trademarks for use in connection with the Licensed Products in the Biogen Territory, and will be solely
responsible for all Trademark Costs incurred for such activities.

TERM AND TERMINATION

14.1

Term.    This  Agreement  will  be  effective  as  of  the  Effective  Date  and,  unless  terminated  earlier  pursuant  to  this
Article14  (Term and Termination), will continue on a Licensed Product-by-Licensed Product and country-by-country basis until the date on
which: (a) in any country in the Biogen Territory, the Royalty Term has expired for all Licensed Products in a Product Class in such country,
and (b) for the Profit-Share Territory, the Parties agree to permanently cease to Commercialize all Licensed Products in a Product Class in the
Profit-Share  Territory  (the  “Term”).    Upon  the  expiration  of  this  Agreement  for  all  Licensed  Products  in  a  Product  Class  in  a  country,  the
licenses granted from Sage to Biogen under this Agreement with respect to such Licensed Products in such Product Class in such country will
become fully‑paid, irrevocable, and perpetual.

14.2

Termination  Prior  to  Effective  Date.    On  the  Effective  Date,  Sage  will  provide  to  Biogen  updated  versions  of  any
schedules required to be provided under Section 11.2 (Representations and Warranties of Sage of the Execution Date and the Effective Date) as
a result of Sage making anew as of the Effective Date the representations and warranties of Section 11.2 (Representations and Warranties of
Sage  of  the  Execution  Date  and  the  Effective  Date).    If  any  of  the  representations  and  warranties  set  forth  in  Section [**],  or  Section  [**]
(Representations and Warranties of Sage as of Execution Date and Effective Date) do not remain true and correct as of the Effective Date to the
same extent as of the Execution Date, then Biogen may terminate this Agreement in its entirety with respect to all Product Classes upon written
notice to Sage [**].

14.3

Termination by Biogen for Convenience.  At any time during the Term, Biogen may terminate this Agreement (a) in
its entirety or (b) on a Product Class-by-Product Class basis for the United States, each Major European Country, or for a Product Class in its
entirety as to the entire Territory, in each case ((a) and (b)), for any reason or no reason upon one hundred and fifty (150) days’ prior written
notice to Sage.

14.4

Termination for Material Breach.

14.4.1

Material Breach.

14.4.1.1

Subject  to  Section  14.4.2  (Disputed  Breach),  Sage  will  have  the  right  to  terminate  this
Agreement upon delivery of written notice to Biogen in the event of any material breach by Biogen of this Agreement, solely with
respect  to  the  Product  Class(es)  and  Region(s)  to  which  such  material  breach  relates,  provided  that  such  termination  will  not  be
effective if such breach has been cured within [**] after written notice thereof is given by Sage to Biogen specifying the nature of
the alleged breach (or, if such default cannot be cured within such [**] period, within [**] after such notice if Biogen commences
actions to cure such default within such [**] period and thereafter diligently continues such actions, but fails to cure the default by
the end of such

105

 
 
[**]). Notwithstanding any provision to the contrary set forth in this Agreement, to the extent a material breach involves the failure
to make a payment when due, such breach must be cured within [**] after written notice thereof is given by Sage to Biogen.

14.4.1.2

Subject  to  Section  14.4.2  (Disputed  Breach),  Biogen  will  have  the  right  to  terminate  this
Agreement  upon  delivery  of  written  notice  to  Sage  in  the  event  of  any  material  breach  by  Sage  of  this  Agreement,  solely  with
respect  to  the  Product  Class(es)  and  Region(s)  to  which  such  material  breach  relates,  provided  that  such  termination  will  not  be
effective if such breach has been cured within [**] after written notice thereof is given by Biogen to Sage specifying the nature of
the  alleged  breach  (or,  if  such  default  cannot  be  cured  within  such  [**]  period,  within  [**]  after  such  notice  if  Sage  commences
actions to cure such default within such [**] period and thereafter diligently continues such actions, but fails to cure the default by
the  end  of  such  [**]).  Notwithstanding  any  provision  to  the  contrary  set  forth  in  this  Agreement,  to  the  extent  a  material  breach
involves the failure to make a payment when due, such breach must be cured within [**] after written notice thereof is given by
Biogen to Sage.

14.4.2

Disputed Breach.  If the alleged breaching Party disputes in good faith the existence of a breach specified
in a notice provided by the other Party in accordance with Section  14.4.1 (Material Breach) and such alleged breaching Party provides the other
Party notice of such dispute within the applicable [**] or [**] cure period, then (a) the non-breaching Party will not have the right to terminate
this Agreement under Section  14.4.1 (Material Breach) and (b) the applicable cure period set forth in Section  14.4.1 (Material Breach) will be
tolled during the pendency of the dispute resolution process set forth in Section 15.3 (Dispute Resolution), in each case ((a) and (b)), unless and
until the dispute resolution process set forth in Section  15.3 (Dispute Resolution) has been completed (including the tolling and cure periods set
forth therein), and in any event the terms of Section 15.3.7 (Tolling) will apply.

14.5

Termination for Insolvency.  To the extent permitted by applicable Law, either Party may terminate this Agreement
upon  the  filing  or  institution  of  bankruptcy,  reorganization,  liquidation,  or  receivership  proceedings,  upon  the  appointment  of  a  receiver  or
trustee over all or substantially all property, or upon an assignment of a substantial portion of the assets for the benefit of creditors by the other
Party; provided, however, that in the case of any involuntary bankruptcy proceeding such right to terminate will only become effective if the
Party consents to the involuntary bankruptcy or such proceeding is not dismissed within [**] after the filing thereof.

14.5.1

All rights and licenses now or hereafter granted by one Party to the other Party under or pursuant to this
Agreement are, for all purposes of Section 365(n) of Title 11 of the United States Code, as amended or analogous provisions of applicable Law
outside the United States (the “Bankruptcy Code”), licenses of rights to “intellectual property” as defined in the Bankruptcy Code. Upon the
filing or institution of bankruptcy, reorganization, liquidation, or receivership proceedings, upon the appointment of a receiver or trustee over
all or substantially all property, or upon an assignment of a substantial portion of the assets for the benefit of creditors by a Party, such Party
agrees that the other Party, as licensee of such rights under this Agreement, will retain and may fully exercise all of its rights and elections
under  the  Bankruptcy  Code.  Subject  to  Section  365  of  the  Bankruptcy  Code,  each  Party  will,  during  the  Term,  create  and  maintain  current
copies or, if not amenable to copying, other appropriate embodiments, to the extent feasible, of all intellectual property rights licensed under
this Agreement. Each Party acknowledges and agrees that “embodiments” of intellectual property rights within the meaning of Section 365(n)
include  laboratory  notebooks,  cell  lines,  product  samples,  and  inventory,  research  studies  and  data,  all  Regulatory  Approvals  (and  all
applications  for  Regulatory  Approval)  and  rights  of  reference  therein,  in  each  case,  to  the  extent  licensed  by  a  Party  to  the  other  Party
hereunder, as well as the Sage Licensed Technology and the Biogen Licensed Technology (as the case may be), and all information related to
the Sage Licensed Technology and the Biogen Licensed Technology (as the case may be).  If (a) a case under the Bankruptcy

106

 
 
Code is commenced by or against the debtor Party, (b) this Agreement is rejected as provided in the Bankruptcy Code and (c) the non-debtor
Party elects to retain its rights hereunder as provided in Section 365(n) of the Bankruptcy Code and upon written request of the non-debtor
Party, then:

14.5.1.1

the non-debtor Party will be authorized to retain and exercise its rights under this Agreement
(including a right to enforce any exclusivity provision contained herein) to intellectual property rights (including all embodiments
thereof) licensed hereunder and held by the debtor Party as such rights existed immediately before the commencement of the case
referenced  in  clause  (a)  of  Section  14.5  (Termination  for  Insolvency)  above,  subject  to  the  provisions  of  Section  365(n)  of  the
Bankruptcy Code related to, among other things, payment of the royalties and waiver of rights to setoff and any claim allowable
under  Section  503(b)  of  the  Bankruptcy  Code  related  to  the  performance  of  this  Agreement,  but  neither  such  provision  nor  such
performance by the non-debtor Party will release the debtor Party from liability resulting from rejection of the license or the failure
to perform such obligations

intellectual property (including any applicable embodiment) held by the debtor Party; and

14.5.1.2

to  the  extent  provided  herein,  the  debtor  Party  will  provide  to  the  non-debtor  Party  any

14.5.1.3

the debtor Party will not interfere with the non-debtor Party’s rights under this Agreement, or
any agreement supplemental hereto, with respect to such intellectual property rights (including such embodiments), including any
right to obtain such intellectual property rights (or such embodiments) from another entity, to the extent provided in Section 365(n)
of the Bankruptcy Code.

14.6

Effect  of  Termination  by  Sage  for  Cause  or  for  Biogen’s  Insolvency,  or  by  Biogen  for  Convenience.    Upon
termination  of  this  Agreement  by  Sage  pursuant  to  Section   14.4.1.1  (Material  Breach)  or  Section  14.5  (Termination  for  Insolvency)  or  by
Biogen pursuant to Section 14.3 (Termination by Biogen for Convenience):

14.6.1

Termination  of  Licenses.    If  this  Agreement  is  terminated  in  its  entirety,  then  all  licenses  granted  under
Article   8 (Licenses) granted under this Agreement with respect to all Licensed 217 Products and all Licensed 324 Products will terminate.  If
this Agreement is terminated in part with respect to the Terminated Products or the Terminated Territory, then all licenses granted by Sage to
Biogen under Section    8.1.1 (License Grant to Biogen; Sage Retained Rights) will terminate solely with respect to the Terminated Products and
the  Terminated  Territory,  as  applicable,  and  all  licenses  granted  by  Biogen  to  Sage  under  Section   8.1.2  (License  Grant  to  Sage;  Biogen
Retained Rights) will terminate solely with respect to the Terminated Products and the Terminated Territory, as applicable.

14.6.2

Reversion  License.  Effective  upon  either  (a)  the  date  of  termination  of  this  Agreement  in  case  of
termination  by  Sage  pursuant  to  Section   14.4.1.1  (Material  Breach)  or  Section  14.5  (Termination  for  Insolvency)  or  termination  of  this
Agreement  in  its  entirety  by  Biogen  pursuant  to  Section  14.3  (Termination  by  Biogen  for  Convenience)  or  (b)  the  date  of  expiration  of  the
specified  notice  period  in  Biogen’s  notice  of  termination  of  this  Agreement  in  part  pursuant  to  Section   14.3  (Termination  by  Biogen  for
Convenience),  subject  to  the  terms  of  this  Section  14.6.2  (Reversion  License),  Biogen,  on  behalf  of  itself  and  its  Affiliates,  hereby  grants
(without  any  further  subsequent  action  required  on  the  part  of  Sage)  to  Sage  and  its  Affiliates,  an  irrevocable,  perpetual  license  for  the
Terminated Products in the Terminated Territory, with the right to grant sublicenses through multiple tiers, under the Reversion Technology
[**] (the “Reversion License”), where the Reversion License will be [**]. If any Reversion Technology is in-licensed by Biogen or any of its
Related Parties, then Biogen will promptly inform Sage of any payment obligations and any other obligations applicable to Sage under such
Third Party agreements and, unless

107

 
 
Sage  elects  to  decline  receiving  a  sublicense  under  such  in-licensed  Reversion  technology  as  part  of  the  Reversion  License,  then  (i)  in
consideration therefor, Sage will pay to Biogen amounts equal to any payments that Biogen owes to any Third Party with respect to such in-
licensed  Reversion  Technology  solely  with  respect  to  the  Terminated  Product  for  the  Terminated  Territory,  with  all  payments  made  in
accordance with Section 9.10 (Other Amounts Payable) and Section 9.11 (Payment Terms) mutatis mutandis, and (ii) Sage’s rights under the
Reversion License will be subject to the applicable terms of the applicable Third Party agreement of which Sage has been made aware.

(Termination  by  Biogen  for  Convenience),  each  Party  will  pay  for  [**],  for  (i)  [**],  or  (ii)  [**],  and  (b)  Biogen  will  pay  for  the  costs  and
expenses  for  all  Clinical  Studies  conducted  by  Biogen  in  support  of  obtaining  Regulatory  Approval  for  Commercialization  in  the  Biogen
Territory that are ongoing prior to the date of the written notice from one Party to the other Party under Section 14.4.1.1  (Material Breach),
Section 14.5 (Termination for Insolvency) or Section  14.3  (Termination  by  Biogen  for  Convenience),  as  applicable,  for  (i)  all  Licensed  217
Products  and  all  Licensed  324  Products,  if  this  Agreement  is  terminated  in  its  entirety,  or  (ii)  a  Region  of  the  Biogen  Territory,  if  this
Agreement is terminated in part with respect to such Region of the Biogen Territory, in each case ((a) and (b)), for a period of [**] after the
effective date of termination of this Agreement (the “Termination Wind-Down Period”).

14.6.4

 Regulatory  Materials;  Commercial  Materials.    Biogen,  on  behalf  of  itself  and  its  Affiliates,  at  its  cost,
will (a) assign to Sage or Sage’s designee possession and ownership of all Regulatory Materials, Pricing and Reimbursement Approvals and
material correspondence and conversation logs solely relating to the applicable Terminated Products in the Terminated Territory, in each case,

Affiliates,  hereby  consents  and  grants  to  Sage  the  right  to  access  and  reference  (without  any  further  action  required  on  the  part  of  Biogen,
whose authorization to file this consent with any Regulatory Authority of the Terminated Territory is hereby granted effective as of the date of
termination) any such item with respect to the applicable Terminated Products in the Terminated Territory.

Sell-Off  and  Appointment  as  Distributor.    If  the  effective  date  of  termination  of  this  Agreement  in  its
entirety  or  of  this  Agreement  in  part,  as  the  case  may  be,  is  after  the  First  Commercial  Sale  in  the  applicable  Terminated  Territory  of  the
applicable  Terminated  Products,  then,  to  the  extent  permitted  by  applicable  Law,  effective  upon  such  date  of  such  termination,  Biogen,  its
Affiliates  and  its  Sublicensees  will  have  the  right  to  sell  any  inventory  of  such  Terminated  Products  intended  for  Commercialization  in  the
Terminated Territory existing as of such date of termination in accordance with

applicable termination, for up to (a) [**] after the effective date of the applicable termination, in the case that Sage has obtained all Regulatory
Approvals required to sell such Terminated Products as of the notice date of the applicable termination or (b) [**] after the effective date of the
applicable termination or such longer time as may be agreed by the Parties, in the case that Sage has not obtained all Regulatory Approvals
required to sell such Terminated Products as of the notice date of the applicable termination (either of ((a) or (b)), the “Commercialization
Wind-Down Period”).  Any Terminated Product sold or disposed of by Biogen, its Affiliates or its Sublicensees in the Terminated Territory
during the Commercialization Wind-Down Period will be subject to applicable payment obligations under Article 9 (Payments).  Within  [**]

Territory remaining in Biogen’s inventory and, subject to the terms of Section 14.6.6 (Continuation of Supply), and Sage may purchase, in its
discretion, any such quantities of the Terminated Product from Biogen at a transfer price equal to (i) [**].  After the Commercialization Wind-
Down Period for a Terminated Product, Biogen or its Related Parties will appoint Sage as exclusive distributor of such Terminated Product in
the Territory and grant Sage the right to appoint sub-distributors, until such time as all Regulatory Approvals for the applicable Terminated
Product  in  the  Territory  have  been  transferred  to  Sage  or  its  designee;  provided  that,  Biogen  will  not  be  required  to  appoint  Sage  as  its
distributor of the applicable Terminated Products as contemplated by this Section 14.6.5 (Sell-Off and Appointment as Distributor) if the terms

the applicable Terminated Products (A) [**] or (B) [**]; further provided that if no such appointment is possible, then [**]. Without limiting
the foregoing, if such termination occurs after the First Commercial Sale of a Terminated Product then, during the Commercialization Wind-
Down Period for such Terminated Product, the Parties will use reasonable efforts to transition all Commercialization activities to Sage as Sage
may reasonably request.

14.6.6

Continuation of Supply.  Upon Sage’s request, if (a) the effective date of termination of this Agreement in

product  with  respect  to  the  applicable  Terminated  Products  for  Commercialization  thereof  in  the  Terminated  Territory,  and  (c)  as  of  the
effective date of such termination, neither Sage nor any of its Related Parties has obtained all necessary Regulatory Approvals to Manufacture
the  applicable  Terminated  Products  and  procured  or  developed  its  own  source  of  finished  product  supply  with  respect  to  the  applicable
Terminated  Products  for  Commercialization  thereof  in  the  Terminated  Territory,  then,  at  Sage’s  option  and  at  Sage’s  sole  cost  and  expense,
Biogen  or  its  Related  Parties  will  supply  to  Sage  such  finished  product  with  respect  to  the  applicable  Terminated  Products  for
Commercialization in the Territory at a price equal to (i) [**] following the applicable effective date of termination of this Agreement in its
entirety or in part and (ii) [**] following the applicable effective date of termination of this Agreement in its entirety or in part.

Affiliates’ rights, title and interest in and to such Reversion Trademarks for the applicable country of the Terminated Territory, pursuant to an
agreement  that  the  Parties  will  negotiate  and  enter  into  after  such  effective  date  of  termination,  which  agreement  will  contain,  to  the  extent

written proposal, which legal brief shall be no more than [**].

Injunctive Relief.  Notwithstanding the dispute resolution procedures set forth in this Section 15.3 (Dispute
Resolution),  in  the  event  of  an  actual  or  threatened  breach  of  this  Agreement,  the  aggrieved  Party  may  seek  equitable  relief  (including
restraining  orders,  specific  performance  or  other  injunctive  relief),  without  first  submitting  to  any  dispute  resolution  procedures
hereunder.  Any claim for such equitable relief will be submitted to the United States District Court for the District of Massachusetts or any
Massachusetts court sitting in Boston so long as one of such courts will have subject matter jurisdiction over such claim, and each Party hereby
irrevocably  consents  to  the  exclusive  jurisdiction  of  such  courts  (and  of  the  appropriate  appellate  courts  therefrom)  in  any  proceeding  with
respect to any such claim and irrevocably waives, to the fullest extent permitted by Law, any objection that it may now or hereafter have to the
laying of the venue of any such proceeding in any such court or that any such proceeding brought in any such court has been brought in an
inconvenient  forum.    Process  in  any  such  proceeding  may  be  served  on  either  Party  anywhere  in  the  world,  whether  within  or  without  the
jurisdiction  of  any  such  court.   Without  limiting  the  foregoing,  each  Party  agrees  that  service  of  process  on  such  Party  in  accordance  with
Section 15.10 (Notices) will be deemed effective service of process on such Party.  Each of the Parties hereby irrevocably waives any and all
right to trial by jury in any such proceeding.

estoppel and laches), as well as all time periods in which a Party must exercise rights or perform obligations hereunder, will be tolled once the
dispute resolution procedures set forth in this Section  15.3 (Dispute Resolution) have been initiated and for so long as they are pending, and the
Parties will c

14.5 (Termination  for  Insolvency), (a)  this  Agreement  will  remain  in  full  force  and  effect,  (b)  the  provisions  of  this  Agreement  relating  to
termination for material breach with respect to such Dispute will not be effective, (c) the time periods for cure under Section 14.4 (Termination

dispute resolution procedure will be tolled, (d) any time periods to exercise rights or perform obligations will be tolled; and (e) neither Party
will issue a notice of termination pursuant to this Agreement based on the subject matter of the Dispute until such Dispute has been resolved in
accordance with the applicable dispute resolution procedure, the outcome of such dispute resolution procedure confirmed the material breach
and the existence of the facts claimed by a Party to be the basis for the asserted material breach and all previously tolled cure periods have run;
provided that if such breach can be cured by (i) the payment of money, the defaulting Party will have an additional [**] within its receipt of the
applicable dispute resolution decision, if necessary in addition to the remainder of any applicable previously tolled cure period, to pay such
amount or (ii) the taking of specific remedial actions, the defaulting Party will have a reasonably necessary period to diligently undertake and

termination can be issued.

then the Parties will substitute valid provisions for such invalid, illegal or unenforceable provisions as may be agreed by the Parties, which
valid  provisions  in  their  economic  effect  are  sufficiently  similar  to  the  invalid,  illegal  or  unenforceable  provisions  that  it  can  be  reasonably
assumed that the Parties would have entered into this Agreement with such valid provisions.  In case such valid provisions cannot be agreed
upon by the Parties, the invalid, illegal or unenforceable nature of one or several provisions of this Agreement will not affect the validity of this
Agreement as a whole, unless the invalid, illegal or unenforceable provisions are of such essential importance to this Agreement that it is to be
reasonably assumed that the Parties would not have entered into this Agreement without the invalid, illegal or unenforceable provisions.

15.11

Compliance  with  Export  Regulations.    Neither  Party  will  export  any  technology  licensed  to  it  by  the  other  Party

under this Agreement except in compliance with U.S. export Laws and regulations.

15.12

Force  Majeure.    Neither  Party  will  be  held  liable  to  the  other  Party  nor  be  deemed  to  have  defaulted  under  or
breached  this  Agreement  for  failure  or  delay  in  achieving  any  objective,  satisfying  any  condition,  or  performing  any  obligation  under  this
Agreement  to  the  extent  that  such  failure  or  delay  is  caused  by  or  results  from  acts  or  events  beyond  the  reasonable  control  of  such  Party,
including acts of God, embargoes, war, acts of war (whether war be declared or not), terrorism, insurrections, riots, civil commotions, strikes,
lockouts,  or  other  labor  disturbances  (other  than  strikes,  lockouts,  or  labor  disturbances  involving  a  Party’s  own  employees),  government
actions, fire, earthquakes, floods, epidemics, pandemics, the spread of infectious diseases, and quarantines  (“Force Majeure”) beyond such
Party’s reasonable control and renders the performance impossible or illegal.  The Parties agree the effects of the

117

 
 
 
 
 
 
 
 
 
 
COVID-19 pandemic that is ongoing as of the Execution Date may be invoked as a Force Majeure for the purposes of this Agreement even
though  the  pandemic  is  ongoing  to  the  extent  those  effects  are  not  be  reasonably  foreseeable  by  the  Parties  as  of  the  Execution  Date.   The
affected Party will notify the other Party in writing of any Force Majeure event that may affect its performance under this Agreement as soon
as reasonably practical, will provide a good faith estimate of the period for which its failure or delay in performance under this Agreement is
expected to continue based on currently available information, and will undertake reasonable efforts necessary to mitigate and overcome such
Force Majeure event and resume normal performance of its obligations hereunder as soon a reasonably practicable under the circumstances.  If
the Force Majeure event continues, then the affected Party will update such notice to the other Party on a weekly basis, or more frequently if
requested by the other Party, to provide updated summaries of its mitigation efforts and its estimates of when normal performance under the
Agreement will be able to resume.

15.13

Relationship of the Parties. This Agreement will not constitute a partnership for any applicable Tax purposes, except
as determined under Schedule 15.21 (Tax Partnership Agreement Terms). For the avoidance of doubt, the joint Commercialization will not be
considered  a  partnership  or  a  joint  venture  for  purposes  of  VAT  (in  non-United  States  jurisdictions)  unless  specifically  agreed  between  the
Parties, and no Party will take any action so as to create a VAT establishment for any joint Commercialization activities in any non-United
States jurisdiction in the Profit-Share Territory.  Except to the extent expressly stated in this Agreement, neither Sage, on the one hand, nor
Biogen, on the other hand, will have the authority to make any statements, representations or commitments of any kind, or to take any action,
that  will  be  binding  on  the  other,  without  the  prior  written  consent  of  the  other  Party  to  do  so.   All  persons  employed  by  a  Party  will  be
employees of such Party and not of the other Party and all costs and obligations incurred by reason of any such employment shall be for the
account and expense of such Party.

15.14

Performance by BIMA and BIG.  BIG unconditionally guarantees to Sage performance of BIMA’s obligations under
this  Agreement  (including  all  agreements,  commitments  to  perform  activities  or  incur  expenditures,  undertakings,  licenses  and  payment
obligations, now or hereafter entered into pursuant to this Agreement) (“Guaranteed Obligations”), and BIMA unconditionally guarantees to
Sage  performance  of  BIG’s  Guaranteed  Obligations.    Each  of  BIG  and  BIMA  agrees  that  the  validity  of  their  respective  guaranties  in  this
Section 15.14  (Performance  by  BIMA  and  BIG)  and  their  respective  obligations  hereunder  will  not  be  terminated,  affected,  diminished  or
impaired  by  reason  of  the  assertion  or  the  failure  to  assert  by  Sage  against  BIMA  or  BIG  any  of  the  rights  or  remedies  reserved  to  Sage
pursuant  to  the  provisions  of  this  Agreement  or  otherwise  or  any  other  remedy  or  right  which  such  Sage  may  have  at  law  or  in  equity  or
otherwise.  The foregoing guarantee will be continuing until all Guaranteed Obligations now existing or hereafter arising have been discharged
in full, and shall be and continue to be fully effective notwithstanding any amendment to this Agreement or any of the Guaranteed Obligations
(but subject to any changes to the Guaranteed Obligations resulting therefrom).  To the extent Sage grants to BIG (a) any waiver of any default
by BIMA of the Guaranteed Obligations, (b) any extension of time of performance by BIMA of the Guaranteed Obligations, or (c) any release
of  BIMA  from  the  performance  of  the  Guaranteed  Obligations,  Sage  will  have  and  be  deemed  to  have  also  granted  the  same  to  BIG
hereunder.  To the extent Sage grants to BIMA (i) any waiver of any default by BIG of its Guaranteed Obligations, (ii) any extension of time of
performance by BIG of its Guaranteed Obligations or (iii) any release of BIG from the performance of its Guaranteed Obligations, Sage will
have  and  be  deemed  to  have  also  granted  the  same  to  BIMA  hereunder.    The  obligations  of  BIG  and  BIMA  under  this  Section  15.14
(Performance  by  BIMA  and  BIG)  will  not  be  subject  to  any  counterclaim,  setoff,  deduction  or  defense  based  on  any  claim  that  such
guaranteeing party may have against the guaranteed party, or any other person or entity, and will remain in full force and effect without regard
to, and will not be released, suspended, abated, deferred, reduced, limited, discharged, terminated or otherwise impaired or adversely affected
by any circumstance or occurrence whatsoever, other than full performance of the respective Guaranteed Obligations.

118

 
 
15.15

Coordination between BIMA and BIG.  It is understood and agreed that any performance due to Biogen by Sage
under  this  Agreement  will  be  deemed  rendered  to  Biogen  to  the  extent  such  performance  by  Sage  is  rendered  to  either  BIMA  or  BIG,  and
BIMA and BIG may only look to the other for any share or benefit from Sage’s obligations under this Agreement.  It is further agreed that
BIMA  and  BIG  will  not  act  separately  under  this  Agreement,  and  with  respect  to  the  exercise  of  the  rights  of  Sage  or  Biogen  under  this
Agreement, BIMA will be deemed to have the authority to bind both itself and BIG and BIG will be deemed to have the authority to bind both
itself and BIMA.  BIMA and BIG will be jointly liable for their obligations under this Agreement, and it is understood and agreed that for
purposes of Section 14.4 (Termination for Material Breach), an uncured breach by either BIMA or BIG will be deemed a breach by both BIMA
and BIG.  Without limiting the foregoing, any notice to or from Biogen and any consent, approval, agreement, actions or inactions of Biogen
under this Agreement will be deemed notices to or from both BIMA and BIG and consent, approval, agreement, actions or inactions by both
BIMA and BIG under this Agreement.

15.16

Expenses.    Except  as  otherwise  provided  herein,  all  fees,  costs  and  expenses  (including  any  legal,  accounting  and
banking  fees)  incurred  in  connection  with  the  preparation,  negotiation,  execution  and  delivery  of  this  Agreement  and  to  consummate  the
transactions contemplated hereby will be paid by the Party hereto incurring such fees, costs and expenses.

15.17

Counterparts.    The  Agreement  may  be  executed  in  two  or  more  counterparts,  including  by  facsimile  or  PDF

signature pages, each of which will be deemed an original, but all of which together will constitute one and the same instrument.

15.18

Performance  by  Affiliates.    Each  Party  acknowledges  and  accepts  that  the  other  Party  may  exercise  its  rights  and
perform its obligations (including granting or continuing licenses and other rights) under this Agreement either directly or through one or more
of  its  Affiliates.    A  Party’s  Affiliates  will  have  the  benefit  of  all  rights  (including  all  licenses  and  other  rights)  of  such  Party  under  this
Agreement,  but  not  be  subject  to  such  Party’s  obligation,  unless  expressly  provided  herein,  or  in  the  case  of  a  permitted  assignment,  in
accordance with Section 15.1 (Assignment).  Accordingly, in this Agreement “Biogen” will be interpreted to mean “Biogen or its Affiliates”
and “Sage” will be interpreted to mean “Sage or its Affiliates” where necessary to give each Party’s Affiliates the benefit of the rights provided
to such Party in this Agreement and the ability to perform its obligations (including granting or continuing licenses and other rights) under this
Agreement; provided, however, that in any event each Party will remain responsible for the acts and omissions, including financial liabilities,
of its Affiliates.

15.19

Binding Effect; No Third Party Beneficiaries. As of the Execution Date, this Agreement will be binding upon and
inure  to  the  benefit  of  the  Parties  and  their  respective  permitted  successors  and  permitted  assigns.    Except  as  expressly  set  forth  in  this
Agreement,  no  Person  other  than  the  Parties  and  their  respective  Affiliates  and  permitted  assignees  hereunder  will  be  deemed  an  intended
beneficiary hereunder or have any right to enforce any obligation of this Agreement.

15.20

Further  Assurances.    The  Parties  agree  to  reasonably  cooperate  with  each  other  in  connection  with  any  actions
required  to  be  taken  in  furtherance  of  their  respective  obligations  under  this  Agreement,  including  (a)  furnishing  to  each  other  such  further
information; (b)  executing  and  delivering  to  each  other  such  other  documents;  and  (c)  doing  such  other  acts  and  things  (including  working
collaboratively to correct any clerical, typographical, or other similar errors in this Agreement), all as the other Party may reasonably request
for the purpose of carrying out the intent of this Agreement.

119

 
 
15.21

Tax Matters.

15.21.1

Tax Treatment.

15.21.1.1

The  Parties  agree  to  treat  the  transactions  contemplated  by  this  Agreement  related  to  the
Profit-Share Territory as a partnership for United States federal and state income Tax purposes between Sage and BIMA (the “Tax
Partnership”), with Sage and BIMA as partners of the Tax Partnership only upon receipt of Regulatory Approval by the FDA with
respect to a Licensed Product to be sold in the Profit-Share Territory; provided, however, that no Tax Partnership will be treated as
being formed if (a) prior to the receipt of such Regulatory Approval by the FDA, Sage exercises its Opt-Out Right with respect to
such  Licensed  Product  or  (ii)  Biogen  reasonably  determines  based  on  the  advice  of  a  nationally  recognized  tax  advisor  that  the
Parties  are  not  required  to  treat  the  transactions  contemplated  by  this  Agreement  as  a  partnership  for  U.S.  Federal  income  tax
purposes.  The Parties shall file all Tax returns consistent with such Tax treatment.  The Parties will work together in good faith to
execute a written tax partnership agreement for the Tax Partnership between BIMA and Sage that will incorporate the principles of
Schedule 15.21 (Tax Partnership Agreement Terms).  

15.21.1.2

Unless Biogen notifies Sage in writing that Biogen has determined that Biogen and Sage will
not  follow  the  tax  treatment  set  forth  in  this  Section  15.21.1.2  (Tax  Treatment),  then  the  Parties  agree  to  treat  the  transactions
contemplated  by  this  Agreement  related  to  the  Biogen  Territory,  including  the  payment  by  BIG  pursuant  to  Section  9.11.6.2
(Payment Allocation), as not being a partnership between any of the Parties for any Tax purposes.  The Parties agree that BIG shall
not be a partner of the Tax Partnership and that the transactions contemplated by this Agreement related to the Biogen Territory shall
be treated as occurring outside of, and separate from, the Tax Partnership.  The Parties shall file all Tax returns consistent with such
Tax treatment.

15.22

HSR  Act.    Notwithstanding  any  provision  to  the  contrary  in  this  Agreement,  the  following  provisions  of  this
Agreement  will  be  in  full  force  and  effect  as  of  the  Execution  Date:  Article  1  (Definitions),  Article  11  (Representations,  Warranties  and
Covenants), Section 14.2 (Termination Prior to Effective Date) and Article 15 (Miscellaneous).  The Confidentiality Agreement between Sage
and  Biogen,  dated  as  of  [**],  as  amended  on  [**],  will  continue  to  be  effective  and,  if  the  Effective  Date  occurs,  shall  terminate  on  the
Effective Date and all information disclosed or exchanged under such agreement will be treated as Confidential Information disclosed under
this Agreement.  Neither Party shall have the right to terminate this Agreement during any HSR clearance period, unless (a) in the event that
the SPA is validly terminated pursuant to Section 9.1 of the SPA prior to Closing as defined in the SPA occurring thereunder, in which case this
Agreement will terminate concurrently with the termination of the SPA or (b) Section 14.2 (Termination Prior to Effective Date) applies,  and,
in each case ((a) or (b)), notwithstanding any provisions that are stated to survive under Section 14.8.2 (Effect of Expiration or Termination;
Survival) all provisions of this Agreement will terminate and be of no force or effect whatsoever.

impairs  the  Company’s  ability  to  perform  its  obligations  pursuant  to  the  transactions  contemplated  by  this  Agreement  or  the
Collaboration  Agreement;  provided  that  none  of  the  following  shall  be  taken  into  account  in  determining  whether  there  is  a

announcement of the execution of, this Agreement or the Collaboration Agreement (provided any such public announcement is not
in breach of this Agreement or the Collaboration Agreement); provided, that, in the case of each of (ii), (iii) and (iv), solely to the
extent  that  such  effects  do  not  have  and  are  not  reasonably  likely  to  have  a  material  disproportionate  impact  on  the  Company

The authorized capital stock of the Company is as set forth in the SEC Filings.  As of October 29,
2020  (the  “Reference  Date”):  (i)  52,044,663  shares  of  Common  Stock  were  issued  and  outstanding,  all  of  which  were  validly
issued and fully paid, nonassessable and free of preemptive rights; (ii) 8,296,925 shares of Common Stock were issuable (and such
number  was  reserved  for  issuance)  upon  exercise  of  outstanding  options  to  purchase  Common  Stock  or  upon  settlement  of
outstanding restricted stock units payable in Common Stock (the “Equity Awards”) outstanding as of such date; and (iii) no shares
of preferred stock, $0.0001 par value per share (“Preferred Stock”), were issued and outstanding.  The Company has not issued
any  capital  stock  since  the  Reference  Date  other  than  shares  duly  issued  pursuant  to  Equity  Awards  and  other  awards  approved
pursuant to Company equity incentive plans or agreements described in the SEC Filings.

(b)

The Company’s disclosure of its issued and outstanding capital stock in its most recent SEC Filing
containing such disclosure was accurate in all material respects as of the date indicated in such SEC Filing.  All of the issued and
outstanding  shares  of  the  Company’s  capital  stock  have  been  duly  authorized  and  validly  issued  and  are  fully  paid  and
nonassessable; none of such shares were issued in violation of any preemptive rights; and such shares were issued in compliance in
all material respects with applicable state and federal securities Law and any rights of Third Parties (as defined below).  The Shares
to be issued in connection with this Agreement, when issued as contemplated herein, will be duly authorized, validly issued, fully
paid and nonassessable, will not be in violation of any preemptive rights and will be free and clear of all liens, charges, restrictions,
claims,  rights  of  first  refusal  and  encumbrances  except  as  set  forth  in  this  Agreement  and  the  Company’s  certificate  of
incorporation, bylaws and documents of similar substance (the “Governing Documents”). The issuance and sale of the Shares will
not obligate the Company to issue shares of Common Stock or other securities to any Person (as defined below) (other than the
Purchaser) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset
price  under  any  of  such  securities.    For  purposes  of  this  Agreement,  “Person”  means  any  natural  person,  corporation,
unincorporated  organization,  partnership,  association,  sole  proprietorship,  joint  stock  company,  joint  venture,  limited  liability
company, trust or government, or Governmental Authority (as defined below), or any other similar entity.

(c)

All of the authorized shares of Common Stock are entitled to one (1) vote per share.

The Company is not a party to or subject to any agreement or understanding relating to the voting of
shares of capital stock of the Company or the giving of written consents by a stockholder or director of the Company other than

creditors’ rights generally or by equitable principles and (B) as limited by Laws relating to the availability of specific performance,
injunctive relief or other equitable remedies (the “Equitable Exceptions”). No action on the part of the Company’s stockholders is

Filing,  and  (ii)  did  not,  at  the  time  it  was  filed  (or  at  the  time  it  became  effective  in  the  case  of  registration  statements),  or,  if
amended, as of the date of the last such amendment, contain any untrue statement of a material fact or omit to state a material fact
required  to  be  stated  therein  or  necessary  in  order  to  make  the  statements  made  therein,  in  the  light  of  the  circumstances  under
which they were made, not misleading.

(b)

Each of the consolidated financial statements (including, in each case, any notes thereto) contained
in the SEC Filings, as amended, supplemented or restated, if applicable, was prepared in accordance with GAAP applied (except as
may be indicated in the notes thereto and, in the case of unaudited quarterly financial statements, as permitted by the Form 10-Q

Company  and  the  consolidated  subsidiaries  of  the  Company  as  of  the  respective  dates  thereof  and  for  the  respective  periods
indicated therein (subject, in the case of unaudited quarterly financial statements, to normal year-end adjustments).

(c)

The Company has implemented and maintains a system of “internal control over financial reporting”
(as defined in Rule 13a-15(f) promulgated under the Exchange Act) that is designed to provide reasonable assurance regarding the
reliability  of  financial  reporting  and  the  preparation  of  consolidated  financial  statements  in  accordance  with  GAAP  for  external
purposes and includes policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and
fairly reflect the transactions and dispositions of the assets of the Company, (ii) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of
the  Company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the  Company,  and
(iii) provide reasonable assurance regarding the prevention or timely detection of unauthorized acquisition, use or disposition of the
Company’s assets that could have a material effect on its financial statements.  

(d)

The Company has implemented and maintains “disclosure controls and procedures” (as defined in
Rule 13a-15(e) promulgated under the Exchange Act) that are designed 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
frames specified by the SEC’s rules and forms.  The Company has conducted evaluations of the

5

 
 
 
effectiveness of its disclosure controls and procedures as required by Rule 13a-15 promulgated under the Exchange Act.

2.5

(a)

The execution and delivery of this Agreement by the Company does not, and the performance of this
Agreement by the Company will not, (i) conflict with or violate any provision of the Governing Documents, (ii) assuming that all
consents,  approvals,  authorizations  and  permits  described  in  the  Collaboration  Agreement  have  been  obtained,  conflict  with  or
violate any Law in any material respect applicable to the Company or by which any property or asset of the Company is bound or
affected  or  (iii)  conflict  with,  or  constitute  a  default  (or  an  event  which,  with  notice  or  lapse  of  time  or  both,  would  become  a
default) in any material respect under, or give to others any rights of termination, amendment, acceleration or cancellation of, any
“material  contract”  (as  such  term  is  defined  in  Item  601(b)(10)  of  Regulation  S-K  promulgated  under  the  Exchange  Act)  of  the
Company.

(b)

The  Company  is  not  required  to  obtain  any  consent,  waiver,  authorization  or  order  of,  give  any
notice to, or make any filing or registration with, any federal, national, foreign, supranational, state, provincial, municipal, local or
other government, governmental, regulatory or administrative authority, agency or commission or any court, tribunal, or judicial or
arbitral body of competent jurisdiction (“Governmental Authority”) or other Person in connection with the execution, delivery
and performance by the Company of the issuance and sale of the Shares, other than (i) (A) the HSR Conditions (as defined below),
(B) the filing of a Notice of Sale of Securities on Form D with the SEC under Regulation D of the Securities Act, (C) the filing of
any  requisite  notices  and/or  application(s)  to  the  Principal  Market  for  the  issuance  and  sale  of  the  Shares  and  the  listing  of  the
Shares thereon in the time and manner required thereby, (D) any filing required by the Collaboration Agreement, and (E) those that
have  been  made  or  obtained  prior  to  the  date  of  this  Agreement,  or  (ii)  where  failure  to  obtain  such  consents,  approvals,
authorizations  or  permits,  or  to  make  such  filings  or  notifications,  would  not,  individually  or  in  the  aggregate,  reasonably  be
expected to have a Material Adverse Effect.

2.6

Litigation.  Other  than  as  set  forth  in  the  SEC  Filings,  there  is  no  action,  suit,  proceeding  or  investigation
pending  (of  which  the  Company  has  received  notice  or  otherwise  has  knowledge)  or,  to  the  Company’s  knowledge,  threatened
against the Company or which the Company intends to initiate, except where such action, suit, proceeding or investigation, as the
case may be, would not reasonably be expected to have a Material Adverse Effect.

2.7

Licenses  and  Other  Rights;  Compliance  with  Laws.  The  Company  has  all  franchises,  permits,  licenses  and
other  rights  and  privileges  (“Permits”)  necessary  to  permit  it  to  own  its  properties  and  to  conduct  its  business  as  presently
conducted and is in compliance thereunder, except where the lack of which or the failure to be in compliance thereunder would not
reasonably be expected to have a Material Adverse Effect. To the Company’s knowledge, the Company has not taken any action
that  would  interfere  with  its  ability  to  renew  all  such  Permit(s),  except  where  the  failure  to  renew  such  Permit(s)  would  not
reasonably be expected to have a Material Adverse Effect. The Company is and has been in compliance with all Laws applicable to
its  business,  properties  and  assets,  except  where  the  failure  to  be  in  compliance  would  not  reasonably  be  expected  to  have  a
Material Adverse Effect.

2.8

Intellectual Property.

(a)

 The trademarks, trade names, trade dress, service marks, copyrights, and similar rights (including
registrations and applications to register or renew the registration of any of the foregoing), patents and patent applications, trade
secrets,  and  any  other  similar  intellectual  property  rights  (“Intellectual  Property”)  that  are  owned  by  the  Company  or  its
subsidiaries  are  owned  free  from  any  liens  or  restrictions.    All  of  the  Company’s  material  licenses,  permits,  authorizations,
approvals,  contracts  or  consents  granted,  issued  by  or  with  any  person  relating  to  the  use  of  Intellectual  Property  (“Intellectual
Property Licenses”) are in full force and effect in accordance with their terms, and neither the Company, nor to the Company’s
knowledge, any other party thereto, is in material breach of any such material Intellectual Property License.  No event has occurred
that (i) with notice or lapse of time or both would constitute a breach or default of any such material Intellectual Property License,
(ii) would result in the termination thereof, or (iii) would cause or permit the acceleration or other change of any right or obligation
or the loss of any benefit thereunder by the Company or its subsidiaries, except (1) in the case of each of (i)-(iii) above as would
not reasonably be expected to have a Material Adverse Effect, or (2) as set forth in any such Intellectual Property License. Except
as set forth in the SEC Filings, there is no legal claim or demand of any person pertaining to, or any proceeding that is pending (of
which the Company has received notice or otherwise has knowledge) or overtly threatened in writing, (i) challenging the right of
the Company in respect of any Intellectual Property of the Company, or (ii) claiming that any default exists under any Intellectual
Property  License,  except,  in  the  case  of  each  of  (i)  and  (ii)  above,  where  any  such  claim,  demand  or  proceeding  would  not
reasonably be expected to have a Material Adverse Effect.

(b)

Except  as  set  forth  in  the  SEC  Filings:  (i)  to  the  knowledge  of  the  Company,  the  Company  or  its
subsidiaries own, free and clear of any lien or encumbrance, or have a valid license, or an enforceable right to use, as it is used or
held for use, all U.S. and non-U.S. patents, trade secrets, know-how, trademarks, service marks, copyrights, and other proprietary
and  intellectual  property  rights,  and  all  grants  and  applications  with  respect  to  the  foregoing  (collectively,  the  “Proprietary
Rights”) necessary for the conduct of the Company’s business, except where the failure to own or have any of the foregoing would
not  reasonably  be  expected  to  have  a  Material  Adverse  Effect  (such  Proprietary  Rights  owned  by  or  licensed  to  the  Company
collectively,  the  “Company  Rights”);  and  (ii)  the  Company  and  its  subsidiaries  have  taken  reasonable  measures  to  protect  the
Company  Rights,  consistent  with  prudent  commercial  practices  in  the  biotechnology  industry,  except  where  failure  to  take  such
measures would not reasonably be expected to have a Material Adverse Effect.

2.9

Listing and Maintenance Requirements. The Common Stock is registered pursuant to Section 12(b) or 12(g) of
the  Exchange  Act,  and  the  Company  has  taken  no  action  designed  to,  or  which  to  its  knowledge  is  likely  to  have  the  effect  of,
terminating the registration of the Common Stock under the Exchange Act nor has the Company received any notification that the
SEC is contemplating terminating such registration. The Company is in compliance with the requirements of the Principal Market
for continued listing of the Common Stock thereon and has not received any notification that the Principal Market is contemplating
terminating such listing. The issuance and sale of the Shares hereunder does not contravene the rules of the Principal Market.

of the Securities Act and are exempt from the qualification or registration requirements of applicable state securities Laws. Neither
the  Company  nor  its  Affiliates  (as  defined  below),  nor  any  agent  on  its  or  their  behalf,  (i)  has  engaged  in  any  form  of  general

sale of the Shares, (ii) has solicited or will solicit any offers to sell or has offered to sell or will offer to sell all or any part of the
Shares  to  any  Person  or  Persons  so  as  to  bring  the  sale  of  the  Shares  by  the  Company  within  the  registration  provisions  of  the
Securities  Act  or  any  state  securities  Laws  or  (iii)  has  issued  any  shares  of  Common  Stock  or  shares  of  any  series  of  Preferred
Stock  or  other  securities  or  instruments  convertible  into,  exchangeable  for  or  otherwise  entitling  the  holder  thereof  to  acquire
shares of Common Stock which would be integrated with the sale of the Shares to Purchaser for purposes of the Securities Act or
of  any  applicable  shareholder  approval  provisions,  including,  under  the  rules  and  regulations  of  any  exchange  or  automated
quotation  system  on  which  any  of  the  securities  of  the  Company  are  listed  or  designated,  nor  will  the  Company  or  any  of  its
subsidiaries or Affiliates take any action or steps that would require registration of any of the Shares under the Securities Act.

the  issuance  and  sale  of  the  Shares  contemplated  by  this  Agreement,  no  event,  liability,  fact,  circumstance,  occurrence  or

this Agreement. All corporate action on the part of Purchaser and, as applicable, its directors, officers, and shareholders, necessary
for  the  authorization,  execution,  delivery  and  performance  of  all  obligations  of  Purchaser  under  this  Agreement  has  been  taken.
This  Agreement  has  been  duly  executed  by  Purchaser  and  constitutes  the  valid  and  legally  binding  obligations  of  Purchaser,
enforceable in accordance with their terms, except as limited by the Equitable Exceptions.

3.2

Investor Representations.

(a)

The Shares acquired by Purchaser hereunder will be acquired by Purchaser for its own account for
investment purposes and not with a view to distribution in violation of the Securities Act. Purchaser does not presently have any
contract,  undertaking  or  agreement  with  any  Person  to  sell,  transfer  or  grant  participation  rights  to  such  Person  or  to  any  other
Person with respect to any of the Shares acquired by Purchaser hereunder.

Securities Act.

Purchaser  is  an  “accredited  investor”  within  the  meaning  of  Rule  501(a)  promulgated  under  the

(c)

Purchaser  understands  that  the  Shares  are  characterized  as  “restricted  securities”  under  the  federal
securities Laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that
under  such  Laws  and  applicable  regulations  such  securities  may  be  resold  without  registration  under  the  Securities  Act  only  in
certain  limited  circumstances.  Purchaser  acknowledges  and  agrees  that  the  Shares  must  be  held  indefinitely  unless  they  are
subsequently registered under the Securities Act or an exemption from such registration is available or the Company receives an
opinion of counsel reasonably satisfactory to the Company that such registration is not required. Purchaser has been advised or is
aware  of  the  provisions  of  Rule  144  promulgated  under  the  Securities  Act  as  in  effect  from  time  to  time  (“Rule  144”),  which
permit limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions.

(d)

Purchaser acknowledges and agrees that it can bear the economic risk of its investment in the Shares
and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the
investment in the Shares. Purchaser has been furnished with materials relating to the offer and sale of the Shares that have been
requested by Purchaser, and Purchaser has had the opportunity to review the SEC Filings. Purchaser further represents that it has
had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of
the Shares.  The foregoing, however, does

9

 
 
 
not modify, amend or affect Purchaser’s right to rely on the truth, accuracy and completeness of the Company’s representations and
warranties contained in Section 2 of this Agreement.

Purchaser has not agreed to incur, directly or indirectly, any liability for brokerage or finders’ fees,
agents’ commissions or other similar charges in connection with this Agreement or any of the transactions contemplated hereby
that would impose any liability of the Company.

(e)

(f)

Purchaser is not relying and has not relied on any representations or warranties whatsoever regarding
the subject matter of this Agreement, express or implied, except for the representations and warranties of the Company set forth in
Section  2,  subject  to  the  exceptions  to  such  representations  and  warranties  set  forth  in  the  Company  Disclosure  Schedule.  Such
representations and warranties by the Company constitute the sole and exclusive representations and warranties of the Company in
connection  with  the  transactions  contemplated  by  this  Agreement  and  Purchaser  understands,  acknowledges  and  agrees  that  all
other representations and warranties of any kind or nature whether express, implied or statutory are specifically disclaimed by the
Company.

3.3

Beneficial  Ownership.  Other  than  with  respect  to  the  Shares  that  the  Purchaser  may  acquire  hereunder,
Purchaser does not “beneficially own” (as defined in Regulation 13D-G under the Exchange Act) any Common Stock, including
any  securities  convertible  into  or  exchangeable  for  Common  Stock  (including  any  such  securities  that  cannot  be  converted  or
exchanged for more than 60 days from the date hereof).

subject to the terms set forth herein, ending on the two (2) year anniversary of the Closing (the “Partial Holding Period”), subject
to the limitations in Section 6.1(d), Purchaser and its Permitted Transferees may take any of the actions set forth in Section 6.1(a)(i)
and Section 6.1(a)(ii) with respect to up to an aggregate of [**]% of the Shares, including the transfer, sale or other disposal of
such Shares.   Each of the Initial Holding Period and the Partial Holding Period are referenced in this Agreement as a “Holding
Period.”  

(c)

During the period beginning the day after the expiration of the Partial Holding Period and ending on
the date one (1) year from the expiration date of the Partial Holding Period (the “Fall-Away Period”), subject to the limitations in
Section 6.1(d), Purchaser and any of its Permitted Transferees may transfer, sell or otherwise dispose of any or all of the Shares
held by Purchaser or any of its Permitted Transferees, as applicable.

(d)

During the Partial Holding  Period  and  the  Fall-Away  Period,  when  selling  the Shares on the open
market or in a block trade, Purchaser and its Permitted Transferees collectively shall be permitted to sell an amount of shares in a
single Trading Day not to exceed [**]% of the average daily volume of the Common Stock as traded on the Principal Market for
the  previous  [**]  prior  to  such  date  (the  “Volume Limitation”); provided,  further,  that,  Purchaser  shall  not,  and  shall  cause  its
Permitted  Transferees  not  to,  intentionally  sell  such  Shares  in  a  block  trade  to  any  Person  that  Purchaser  or  such  Permitted
Transferee  knows  (after  reasonable  inquiry)  is  a  Competitor  (as  defined  below)  of  the  Company.    For  the  purposes  of  this
Agreement,  a  “Competitor”  shall  mean  any  operating  company  with  a  biopharmaceutical  business,  or  any  other  Person  that
directly or indirectly beneficially owns a majority of the voting securities of or voting interests in such a company, or any direct or
indirect majority-owned subsidiary of such a company or of such a Person. Notwithstanding the foregoing, this Section 6.1(d) will
not preclude, and the

12

 
 
 
Volume  Limitation  shall  not  apply  to,  sales  of  the  Shares  by  Purchaser  (i)  pursuant  to  Section  6.1(h)  or  (ii)  as  part  of  an
Underwritten Offering (as defined below) or a Piggyback Registration after Purchaser has exercised any of its registration rights set
forth in Section 6.2.

(e)

Notwithstanding  the  foregoing  Sections  6.1(a),  6.1(b),  6.1(c),  and  6.1(d),  Purchaser  may  transfer
such Shares to a Permitted Transferee; provided that in the case of any transfer or distribution pursuant to and in accordance with
the terms of this Section 6.1(e) during a Holding Period or the Fall-Away Period, each Permitted Transferee shall sign and deliver a
lock-up letter with terms substantially similar to the terms of this Section  6.1.    For  the  purposes  of  this  Agreement,  “Permitted
Transferee” shall mean (i) a controlled Affiliate of Purchaser that is wholly owned, directly or indirectly, by Purchaser, or (ii) a
controlling Affiliate of Purchaser (or any controlled Affiliate of such controlling Affiliate) that wholly owns, directly or indirectly,
Purchaser,  or  the  acquiring  Person  in  the  case  of  a  Change  of  Control  of  Purchaser  (replacing  references  to  “Company”  with
“Purchaser” in the definition of “Change of Control”); it being understood that for purposes of this definition “wholly owned” shall
mean  an  Affiliate  in  which  Purchaser  owns,  or  an  Affiliate  that  owns,  as  applicable,  directly  or  indirectly,  at  least  ninety-nine
percent (99%) of the outstanding capital stock of such Affiliate or Purchaser, as applicable.

with respect to any proposed sale, pledge, or transfer not in compliance with the conditions specified in this Agreement.

(f)

Purchaser acknowledges that the Company may issue stop-transfer instructions to its transfer agent

Each certificate, instrument, or book entry representing the Shares and any other securities issued in
respect of the Shares upon any stock split, stock dividend, recapitalization, merger, consolidation, or similar event, shall (unless
otherwise permitted by the provisions of this clause (g)) be notated with a legend substantially in the following form:

(g)

THE  SECURITIES  REPRESENTED  HEREBY  HAVE  BEEN  ACQUIRED  FOR
INVESTMENT  AND  HAVE  NOT  BEEN  REGISTERED  UNDER  THE  SECURITIES
ACT  OF  1933.  SUCH  SHARES  MAY  NOT  BE  SOLD,  PLEDGED,  OR
TRANSFERRED  IN  THE  ABSENCE  OF  SUCH  REGISTRATION  OR  A  VALID
EXEMPTION  FROM  THE  REGISTRATION  AND  PROSPECTUS  DELIVERY
REQUIREMENTS OF SAID ACT.

THE  SECURITIES  REPRESENTED  HEREBY  MAY  BE  TRANSFERRED  ONLY  IN
ACCORDANCE  WITH  THE  TERMS  OF  AN  AGREEMENT  BETWEEN  THE
COMPANY  AND  THE  STOCKHOLDER,  A  COPY  OF  WHICH  IS  ON  FILE  WITH
THE SECRETARY OF THE COMPANY.

Purchaser consents to the Company making a notation in its records and giving instructions to any transfer agent of the Common
Stock  in  order  to  implement  the  restrictions  on  transfer  set  forth  herein.    The  Company  shall  cause  the  legends  set  forth  in  this
Section  6.1(g)  to  be  removed  from  any  certificate  evidencing  the  Shares  (or  if  the  Shares  are  held  in  book-entry  form,  any
restrictions on transfer noted with respect thereto shall be removed) no later than two (2) Business Days from receipt of a request
from Purchaser following the expiration of the Partial Holding Period or such

13

 
 
 
earlier  date  on  which  the  restrictions  on  dispositions  of  the  Shares  terminates  in  accordance  with  this  Agreement,  if:  (i)  such
securities have been resold under an effective registration statement under the Securities Act, (ii) such securities have been or will
be transferred in compliance with Rule 144 under the Securities Act, (iii) such securities are eligible for resale pursuant to Rule
144(b)(1)(i) under the Securities Act or (iv) the Investor shall have provided the Company with an opinion of counsel, reasonably
satisfactory to the Company, stating that such securities may lawfully be transferred without registration under the Securities Act.

(h)

Notwithstanding any other provision of this Section  6.1, this Section  6.1 shall not prohibit or restrict
any disposition of Common Stock by Purchaser (i) to the Company, (ii) in connection with a Change of Control of the Company
(as defined below), or (iii) in connection with (A) a bona fide tender offer by a Person other than Purchaser or the Company or
(B) an issuer tender offer by the Company; provided, that in the event that any such tender offer is not completed, the Shares shall
remain subject to the restrictions contained in this Section  6.1. For the purposes of this Agreement, a “Change of Control” means
the transfer, in one transaction or a series of related transactions, to a Person or group of affiliated Persons, of shares of capital
stock of the Company if, after such transfer, the stockholders of the Company immediately prior to such transfer do not own at
least a majority of the outstanding voting securities of the Company (or the surviving entity).

6.2

Registration Rights.

(a)

Demand Registration Rights.

(i)

Short-Form Registration.   At  any  time  within  the  [**]  period  following  the  expiration  of
the  Initial  Holding  Period  (such  period,  the  “Registration Period”),  when  the  Company  is  eligible  to  use  Form  S-3,  Purchaser
shall be entitled to request, and the Company shall use commercially reasonable efforts to cause, registration under the Securities
Act of the resale of all or part of the Registrable Shares (as defined below) that are no longer subject to a Holding Period under
Section  6.1  of  this  Agreement,  on  Form  S-3  or  any  similar  short-form  registration  statement  (a  “Short-Form  Demand
Registration Statement”); provided, however, that with respect to any request under this Section 6.2(a)(i), so long as the market
value of all remaining Registrable Shares at the time of the request exceeds the lesser of (i) $[**] or (ii) 100% of the aggregate
Purchase  Price  of  the  Shares  issued  and  sold  under  this  Agreement,  in  each  case  based  on  the  then-current  market  price  of  the
Common Stock (such lesser amount, the “S-3 Floor”),  such  request  shall  cover  Registrable  Shares  worth  at  least  the  S-3  Floor.
Upon receipt of a written request for a Short-Form Demand Registration, the Company will use its commercially reasonable efforts
to (i) cause the Short-Form Demand Registration Statement to be filed with the Commission as soon as practicable, but in no event
more than [**], after receiving the request and (ii) effect the registration under the Securities Act. A registration requested pursuant
to this Section 6.2(a)(i) is referred to herein as a “Short-Form Demand Registration.”

(ii)

Shelf Registration.

At any time the Company is eligible to use a Short-Form Demand Registration
Statement  and  within  the  Registration  Period,  Purchaser  shall  be  entitled  to  request  that  the  Company  file  a  shelf  registration
statement on Form S-3 (provided that in the event

A.

14

 
 
 
 
the Company is a well-known seasoned issuer as defined by Rule 405 promulgated under the Securities Act at the time of the filing
of such registration, such registration will be an automatic shelf registration statement), to register the resale of all or part of the
Registrable  Shares  that  are  no  longer  subject  to  a  Holding  Period  under  Section  6.1  of  this  Agreement,  pursuant  to  Rule  415
promulgated under the Securities Act (including the prospectus, amendments and supplements to the shelf registration statement or
prospectus, including pre- and post-effective amendments, all exhibits thereto and all material incorporated by reference or deemed
incorporated by reference, if any, in such shelf registration statement) (the “Shelf Registration Statement” and, together with the
Short-Form Demand Registration Statement, the “Demand Registration Statements”). A registration requested pursuant to this
Section 6.2(a)(ii)(A), including a shelf takedown from a Shelf Registration Statement, is referred to herein as a “Shelf Demand
Registration” (and, together with the Short-Form Demand Registration, the “Demand Registrations”).

B.

The  Company  shall  use  commercially  reasonable  efforts  to  cause  the  Shelf
Registration Statement to (i) be filed with the Commission as soon as practicable, but in no event more than [**], after receiving
the  Shelf  Demand  Registration  request  and  (ii)  become  or  be  declared  effective  by  the  Commission  as  soon  as  practicable  after
such filing, and shall use commercially reasonable efforts to keep the Shelf Registration Statement effective, from the date such
Shelf  Registration  Statement  becomes  effective  until  the  earlier  to  occur  of  (x)  the  first  date  as  of  which  all  of  the  Registrable
Shares included in the Shelf Registration Statement have been sold or (y) [**] after such date of effectiveness.

C.

Purchaser  shall  be  limited  to  an  aggregate  total  of  [**]  Demand  Registrations;
provided  (i)  the  number  of  shelf  takedowns  that  are  not  Underwritten  Offerings  shall  not  be  limited,  and  (ii)  subject  to
Section 6.2(a)(vi), each Demand Registration shall be an Underwritten Offering if Purchaser so advises the Company as a part of
its request to file a Demand Registration Statement.  For the purposes of this Agreement, an “Underwritten Offering” shall mean
an offering registered under the Securities Act in which securities of the Company are sold to one or more underwriters on a firm-
commitment basis for reoffering to the public, and the plan of distribution contemplates a customary “road show” (including an
“electronic road show”) or other substantial marketing effort by the Company and the underwriters.

(iii)

Payment of Expenses for Demand Registrations.  The Company will pay all Registration
Expenses  (as  defined  below)  for  the  Demand  Registrations  permitted  under  Sections  6.2(a)(i)  and  6.2(a)(ii).    Other  than  as
provided by this Section 6.2(a)(iii) and Section 6.2(c), a registration will not count as a Demand Registration until the registration
statement has become effective and, with respect to an underwritten shelf takedown, the prospectus supplement for such offer has
been  filed  with  the  Commission;  provided,  however  that  if  Purchaser  fails  to  reimburse  the  Company  for  reasonable  and
documented Registration Expenses with respect to a withdrawn Demand Registration in accordance with Section 6.2(c), Purchaser
shall forfeit such withdrawn Demand Registration.

Priority.    In  the  case  of  an  Underwritten  Offering,  if  the  managing  underwriters  with
respect to a Demand Registration advise the Company in writing that, in their opinion, the inclusion of the number of Registrable
Shares and other securities to be included in such underwritten offering creates a substantial risk that the price per share will be
materially

(iv)

15

 
 
 
reduced, the number of securities that in the opinion of such underwriters can be sold without creating such risks shall be allocated
to Purchaser on a pari passu basis with each other holder of other securities having registration rights, on a pro rata basis based on
the  total  number  of  securities  held  by  such  Person.    Notwithstanding  the  foregoing,  in  no  event  will  a  Demand  Registration
pursuant  to  Sections  6.2(a)(i)  and  6.2(a)(ii)  count  as  a  Demand  Registration  for  purposes  of  Section  6.2(a)(ii)(C)  unless  (i)  all
Registrable Shares requested to be registered in such Demand Registration by Purchaser are, in fact, registered in such registration
if the offering is not underwritten, or (ii) at least [**] percent ([**]%) of all Registrable Shares requested to be registered in such
Demand Registration by Purchaser are, in fact, registered in such registration if the offering is underwritten.

(v)

Restrictions.

A.

The  Company  will  not  be  obligated  to  effect  any  Demand  Registration  within
[**] after the effective date of (i) a previous Demand Registration Statement; or (ii) a previous Piggyback Registration Statement
(as  defined  below)  under  which  the  Stockholder  requesting  the  Demand  Registration  had  piggyback  rights  pursuant  to
Section 6.2(b) below wherein Purchaser was permitted to register and sold at least [**]% of the Registrable Shares included in such
Piggyback  Registration  Statement  (as  defined  below).    Further,  the  Company  will  not  be  obligated  to  effect  any  Demand
Registration  pursuant  to  this  Section  6.2(a)  if  the  requested  Demand  Registration  Form  is  not  available  for  such  offering
contemplated by Purchaser or if the Company would be required to qualify to do business or to execute a general consent to service
of process in any particular jurisdiction where it is not already so qualified in effecting such registration.

B.

The Company may postpone the filing of a Demand Registration Statement for a
reasonable  “blackout  period”  not  in  excess  of  [**]  (and  the  time  periods  with  respect  to  filing  or  effectiveness  thereof  shall  be
tolled correspondingly), if (i) the Board of Directors determines in good faith that such registration or offering would be reasonably
likely  to  materially  interfere  with  a  bona  fide  business,  financing  or  business  combination  transaction  of  the  Company  or  is
reasonably likely to require premature disclosure of material non-public information, which premature disclosure could materially
and adversely affect the Company, (ii) such registration would require the Company to recast its historical financial statements or
prepare  pro  forma  financial  statements,  acquired  business  financial  statements  or  other  information,  with  which  requirement  the
Company is reasonably unable to comply, or (iii) render the Company unable to comply with requirements under the Securities Act
or the Exchange Act.

(vi)

Selection  of  Underwriters.    In  connection  with  any  underwritten  Demand  Registration,
Purchaser shall have the right to (i) determine the plan of distribution and (ii) select the investment banker or bankers and managers
to  administer  the  offering,  including  the  lead  managing  underwriter;  provided  that  the  selection  of  such  investment  banker  or
bankers  and  managers  shall  be  subject  to  the  approval  of  the  Company,  which  approval  shall  not  be  unreasonably  withheld  or
delayed.

(b)

Piggyback Registrations.

16

 
 
 
(i)

Right to Piggyback.  At any time during the Registration Period, whenever the Company
proposes  to  register  the  issuance  or  sale  of  any  of  its  Common  Stock  under  the  Securities  Act  for  its  own  account  or  otherwise
(including the registration of shares of Common Stock on behalf of other holders), and the registration form to be used may be used
for the registration of the resale of Registrable Shares (each, a “Piggyback Registration”) (except for the registrations on Form S-
8 or Form S-4 or any successor form thereto) (a “Piggyback Registration Statement”), the Company will give written notice, at
least [**] prior to the proposed filing of such registration statement, to Purchaser of its intention to effect such a registration and
will  use  commercially  reasonable  efforts  to  include  in  such  registration  all  Registrable  Shares  that  are  no  longer  subject  to  a
Holding Period under Section 6.1 of this Agreement (in accordance with the priorities set forth in Sections 6.2(b)(ii) and (b)(iii)
below) with respect to which the Company has received written requests for inclusion, which request shall specify the number of
such  Registrable  Shares  desired  to  be  registered  and  be  delivered  within  [**]  after  the  delivery  of  the  Company’s  notice.    The
Company may postpone or withdraw the filing or the effectiveness of a Piggyback Registration Statement at any time in its sole
discretion.

(ii)

Priority on Primary Registrations.  If a Piggyback Registration is an underwritten primary
offering on behalf of the Company and the managing underwriter(s) thereof advise the Company in writing that a limitation on the
number  of  shares  of  Common  Stock  which  may  be  included  in  the  registration  statement  is  necessary  because,  in  such
underwriter(s)’ judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then the
managing underwriter(s) and the Company may exclude only such number of securities (including Registrable Shares) from the
registration and the underwriting that the managing underwriter(s) advise the Company is necessary to facilitate public distribution,
and the number of securities that may be included in such registration and underwriting shall include: (i) first, any securities that
the  Company  proposes  to  sell,  and  (ii)  second,  pari  passu  among  Purchaser  and  each  other  holder  of  other  securities  having
registration rights that has requested securities be included in such registration, on a pro rata basis based on the total number of
Registrable Shares held by Purchaser and the total number of any other securities held by other holders having registration rights.

(iii)

Priority  on  Secondary  Registrations.    If  a  Piggyback  Registration  is  an  underwritten
secondary offering on behalf of holders of the Company’s securities and the managing underwriter(s) thereof advise the Company
in  writing  that  a  limitation  on  the  number  of  shares  of  Common  Stock  which  may  be  included  in  the  registration  statement  is
necessary  because,  in  such  underwriter(s)’  judgment,  marketing  or  other  factors  dictate  such  limitation  is  necessary  to  facilitate
public  distribution,  then  the  managing  underwriter(s)  and  the  Company,  the  Company  will  include  in  such  registration  the
maximum aggregate number of Registrable Shares requested to be included therein by Purchaser and other registrable securities
requested to be included therein by other holders having registration rights that the managing underwriter(s) advise the Company
can be included such that no further limitation is necessary to facilitate public distribution, on a pro rata basis based on the total
number of Registrable Shares held by Purchaser hereunder and the total number of registrable securities held by such other holders
having registration rights.

Selection of Underwriters.  In connection with any underwritten Piggyback Registration
initiated  by  the  Company,  the  Company  shall  have  the  sole  and  exclusive  right  to  (i)  determine  the  plan  of  distribution  and
(ii) select the investment banker or bankers and

(iv)

17

 
 
 
managers to administer the offering, including the lead managing underwriter. If Purchaser disapproves of the terms of any such
underwriting, Purchaser may elect to withdraw therefrom by written notice to the Company and the underwriter, delivered at least
three (3) days prior to the effective date of the registration statement.

Expenses for the Piggyback Registrations under this Section 6.2(b).

(v)

Payment of Expenses for Piggyback Registrations.  The Company will pay all Registration

(c)

Registration  Expenses.    Other  than  as  provided  by  Section  6.2(a)(iii),  the  Company  will  pay  all
expenses  incurred  by  the  Company  incident  to  the  Company’s  registration  obligations  under  this  Agreement,  including:  all
registration and filing fees; fees and expenses of compliance with securities or blue sky Laws; fees and expenses associated with
listing the Registrable Shares on any securities exchange or market; fees and expenses incurred in connection with the Financial
Industry Regulatory Authority (FINRA) and rating agencies; costs and expenses related to analyst and investor presentations and
“roadshows”; printing expenses; messenger and delivery expenses; and fees and disbursements of counsel for the Company; fees
and  disbursements  of  the  Company’s  registered  public  accounting  firm  (including  with  respect  to  “comfort  letters”);  reasonable
fees and disbursements of all other Persons retained by the Company; and any other fees and disbursements customarily paid by
issuers  of  securities  (all  such  expenses  being  herein  called  “Registration  Expenses”);  provided,  however,  that,  as  between  the
Company  and  Purchaser,  underwriting  discounts,  commissions,  transfer  taxes  and  underwriter  fees  and  disbursements  (in
the  Registrable  Shares  will  be  borne  by
connection  with  an  underwritten  Demand  Registration) 
Purchaser.    Notwithstanding  the  foregoing,  if  a  request  for  Demand  Registration  for  which  the  Company  is  obligated  to  pay  all
Registration  Expenses  pursuant  to  Section  6.2(a)(iii)  and  this  Section  6.2(c)(i)  is  subsequently  withdrawn  at  the  request  of
Purchaser, Purchaser shall forfeit such Demand Registration unless Purchaser pays (or reimburses the Company) for all reasonable
and documented Registration Expenses with respect to such withdrawn Demand Registration; provided that if, at the time of such
withdrawal,  Purchaser  shall  have  learned  of  a  material  adverse  change  in  the  condition,  business,  or  prospects  of  the  Company
from that known to Purchaser at the time of its request and has withdrawn the request with reasonable promptness after learning of
such information, then Purchaser shall not be required to pay any of such expenses and shall not forfeit its right to such Demand
Registration.

relating 

to 

(d)

Registrable  Shares.    For  the  purposes  of  this  Section  6.2,  “Registrable  Shares”  shall  mean  the
Shares held by Purchaser including any shares of Common Stock paid, issued or distributed in respect of any such Shares by way
of stock dividend, stock split or distribution, or in connection with a combination of shares, recapitalization, reorganization, merger
or consolidation, or otherwise, but excluding shares of Common Stock acquired in the open market before or after the date hereof,
provided, however, that the Shares will cease to be “Registrable Shares” when the Shares have been sold pursuant to an effective
registration statement or distributed to the public pursuant to Rule 144 (or any successor provision then in effect).

18

 
 
 
6.3

Notifications.

Prior to the Closing, the Company will promptly advise Purchaser in writing of any notice or other
communication  from  any  Third  Party  alleging  that  the  consent  of  a  Third  Party  is  required  in  connection  with  the  transactions
contemplated by this Agreement.

(a)

Prior to the Closing, each Party shall promptly notify the other of any action, suit or proceeding that
is instituted or specifically threatened in writing against such Party to restrain, prohibit or otherwise challenge the legality of any
transaction contemplated by this Agreement.

(b)

Standstill Termination Date (as defined below), (ii) the date on which any Third Party unaffiliated with Purchaser commences a
tender offer or exchange offer for more than 50% of the Company’s outstanding Common Stock, and (iii) the date the Company
publicly  announces  its  intent  to  consummate  a  Change  of  Control  (the  “Standstill  Period”),  neither  the  Purchaser  nor  any  of
Purchaser’s Representatives will, in any manner, directly or indirectly:

(a)

make,  effect,  initiate  or  cause  (i)  any  acquisition  of  beneficial  ownership,  directly  or  indirectly,  of
any  securities  of  the  Company  or  any  securities  of  any  subsidiary  of  the  Company  other  than  as  contemplated  in  Section   1.1,
(ii) any acquisition of any assets of the Company or any assets of any subsidiary of the Company, (iii) any tender offer, exchange
offer, merger, business combination, recapitalization, restructuring, liquidation, dissolution or extraordinary transaction involving
the Company or any subsidiary of the Company, or involving any securities or assets of the Company or any securities or assets of
any subsidiary of the Company or (iv) any “solicitation” of “proxies” (as those terms are used in the proxy rules of the SEC) or
consents with respect to any securities of the Company; provided that any investment in third-party mutual funds or other similar
passive investment vehicles that hold interests in securities of the Company or any of its subsidiaries shall not be taken into account
for the purpose of this subparagraph;

thereunder) with respect to the beneficial ownership of any securities of the Company;

Notwithstanding the foregoing, it is understood and agreed that Purchaser shall not be prohibited from entering into an
agreement  and  having  discussions  with  legal,  accounting  or  financial  advisors  for  the  limited  purposes  of  evaluating  any  of  the
transactions  contemplated  by  this  Section   6.4,  and  Purchaser  may  initiate  private  discussions  with,  and  submit  proposals
confidentially  to,  the  Chief  Executive  Officer  of  the  Company  regarding  a  transaction  otherwise  prohibited  by  this  Section   6.4;
provided,  however,  that  any  such  proposal  shall  be  expressly  conditioned  on  approval  of  the  Board  of  Directors  and  will  not
reasonably be expected to require public disclosure.  For the purposes of this Agreement, the “Standstill Termination Date” shall
mean the first to occur of: (i) [**]; (ii) the date one (1) year following the effective date of the termination of the Collaboration
Agreement; and (iii) the seventh anniversary of the Effective Date (with “Regulatory Approval,” “FDA,” “Licensed 217 Product,”
and “MDD” having the definitions given them in the Collaboration Agreement).

6.5

Voting Agreement.

(a)

If the Company and its Chief Executive Officer and/or Chief Operating Officer, in their capacities as
officers  of  the  Company  (each,  a  “Proxyholder”  and,  collectively,  the  “Proxyholders”),  instruct  Purchaser  and/or  any  of  its
Permitted Transferees in writing to vote in favor of, or against, any matter, action, ratification or other event for which approval of
the holders of the Company’s stock is sought (either by vote or written consent) or upon which such holders are otherwise entitled
to vote, including the election of directors, but excluding any Extraordinary Matter (as defined below) (collectively, a “Company
Stockholder Matter”),  then  Purchaser,  after  receiving  proper  notice  of  any  meeting  of  stockholders  of  the  Company  related  to
such Company Stockholder Matter (or, if no notice is required or such notice is properly waived, after notice from a Proxyholder is
given), will, and will cause any Permitted Transferees to, (i) be present, in person or by proxy, as a holder of Shares at all such
meetings and be counted for the purposes of determining the presence of a quorum at such meetings and (ii) vote (in person, by
proxy or by action by written consent, as applicable) all Shares as to which Purchaser or Permitted Transferee, as applicable, has
beneficial ownership or as to which Purchaser or Permitted Transferee otherwise exercises voting or dispositive authority in the
manner directed by a Proxyholder.

(b)

Extraordinary  Matters.  Purchaser  and  any  Permitted  Transferee  may  vote  or  execute  a  written
consent with respect to, any or all of the voting securities of the Company as to which it is entitled to vote or execute a written
consent, as it may determine in its sole discretion, with respect to the following matters, if presented to the Company’s stockholders

Definitions.    The  following  terms  shall  apply  with  respect  to  this  Section  7  and  as  used  elsewhere  in  this

of,  the  management  and  policies  of  such  other  Person,  whether  through  ownership  of  voting  securities,  by  contract,  or
otherwise.  The Parties acknowledge that in the case of certain entities organized under the Laws of certain countries outside the
United States, the maximum percentage ownership permitted by Law for a foreign investor may be less than fifty percent (50%),
and that in such case such lower percentage will be substituted in the preceding sentence; provided that such foreign investor has
the power to direct the management and policies of such entity.   For clarity, a Person may be or become an Affiliate of another
Person and may cease to be an Affiliate of such Person, in each case, during the Term of this Agreement.

SEVERANCE AND CHANGE IN CONTROL AGREEMENT

This Severance and Change in Control Agreement (this “Agreement”) is made as of the 15th day of December, 2020 by

and between Sage Therapeutics, Inc., a Delaware corporation (the “Company”), and Barry E. Greene (the “Executive”).

1.

Purpose.  The Company considers it essential to the best interests of its stockholders to promote and preserve

the continuous employment of key management personnel.  The Board of Directors of the Company (the “Board”) recognizes that,
as is the case with many corporations, the possibility of a Change in Control (as defined in Section 2 hereof) exists and that such
possibility, and the uncertainty and questions that it may raise among management, may result in the departure or distraction of key
management personnel to the detriment of the Company and its stockholders.  Therefore, the Board has determined that appropriate
steps should be taken to reinforce and encourage the continued attention and dedication of members of the Company’s key
management, including the Executive, to their assigned duties without distraction, including in the face of potentially disturbing
circumstances arising from the possibility of a Change in Control.  Nothing in this Agreement shall be construed to affect the at-
will nature of the employment relationship between the Executive and the Company, and the Executive shall not have any right to
be retained in the employ of the Company for any definite term or period of time.

2.

Change in Control.  A “Change in Control” shall be deemed to have occurred upon the occurrence of any one
of the following events: (a) the sale of all or substantially all of the assets of the Company on a consolidated basis to an unrelated
person or entity, (b) a merger, reorganization or consolidation pursuant to which the holders of the Company’s outstanding voting
power and outstanding stock immediately prior to such transaction do not own a majority of the outstanding voting power and
outstanding stock or other equity interests of the resulting or successor entity (or its ultimate parent, if applicable) immediately
upon completion of such transaction, (c) the sale of all of the stock of the Company to an unrelated person, entity or group thereof
acting in concert, or (d) any other transaction in which the owners of the Company’s outstanding voting power immediately prior to
such transaction do not own at least a majority of the outstanding voting power of the Company or any successor entity
immediately upon completion of the transaction other than as a result of the acquisition of securities directly from the Company.

3.

Terminating Event.

A “Terminating Event” shall mean any of the following events in this Section 3 subject to  the exceptions noted:

(a)

Termination by the Company.  Termination by the Company of the employment of the Executive

with the Company for any reason other than for Cause, death or Disability.  For purposes of this Agreement, “Cause”
shall mean, as determined

 
 
 
by the Company in good faith and communicated to the Executive in writing specifying with reasonable particularity the
facts and circumstances giving rise to such determination:

(i)

the indictment or conviction of, or pleading of guilty or no contest by, the Executive of any

felony, any crime involving the Company, or any crime involving fraud, moral turpitude or dishonesty;

(ii)

any material breach by the Executive of any agreement between the Executive and the

Company, including without limitation any agreement relating to confidentiality, assignment of inventions,
non-competition and/or non-solicitation, including, without limitation, the Agreement Concerning Loyalty,
Confidential Business Information, Inventions and Noncompetition entered into by Executive in connection
with Executive’s employment (the “Restrictive Covenants Agreement”);

(iii)

any material violation by the Executive of the Company’s written policies, including
without limitation any code of conduct, anti-discrimination and/or anti-harassment policy, and/or insider
trading policy;

(iv)

the Executive’s failure to cooperate with an internal investigation, or an investigation by
regulatory or law enforcement authorities, after being instructed by the Company to cooperate, or the willful
destruction or failure to preserve documents or other materials known to be relevant to such investigation, or
the willful inducement of others to fail to cooperate or produce documents or other materials in connection
with any such investigation;

(v)

any unauthorized use or disclosure of the Company’s Proprietary Information.  As used in

this paragraph, “Proprietary Information” means any information in whatever form, tangible or intangible,
related to the business of the Company unless the information is publicly available through lawful means;

(vi)

any conduct by the Executive that is reasonably likely to be materially harmful to the

business, interests or reputation of the Company; or

(vii)

the Executive’s willful failure to perform, or material negligence in the performance of,

the duties, functions and responsibilities of the Executive’s position after a written warning from the Company
and a period of at least 30days’ opportunity to cure.

A Terminating Event shall not be deemed to have occurred pursuant to this Section 3(a) solely as a result of the
Executive becoming an employee of any direct or indirect successor to the business or assets of the Company, rather than
continuing as an employee of the Company following a Change in Control.  For purposes hereof, the Executive will be considered
to have a “Disability” if, as a result of the Executive’s incapacity due to physical or mental illness, the Executive shall have been
absent from the Executive’s duties to the Company on a full-time basis for 180 calendar days in the aggregate in any 12-month
period.

 
 
 
(b)

Termination by the Executive for Good Reason.  Termination by the Executive of the Executive’s
employment with the Company for Good Reason.  For purposes of this Agreement, “Good Reason” shall mean that the
Executive has complied with the “Good Reason Process” (hereinafter defined) following the occurrence of any of the
following events without the Executive’s written consent:

(i)

a material diminution in the Executive’s responsibilities, authority or duties;

(ii)

a material diminution in the Executive’s base salary except for across-the-board salary
reductions based on the Company’s financial performance similarly affecting all or substantially all senior
management employees of the Company;

(iii)

a material change, defined as 50 miles or more, in the geographic location at which the

Executive is required to provides services to the Company (unless such new location is closer to the
Executive’s residence at the time such change is imposed), not including business travel and short-term
assignments; or

(iv)

a material breach of this Agreement by the Company.

“Good Reason Process” shall mean that (i) the Executive reasonably determines in good faith that a “Good Reason”
condition has occurred; (ii) the Executive notifies the Company in writing of the first occurrence of the Good Reason condition
within 30 days of the first occurrence of such condition; (iii) the Executive cooperates in good faith with the Company’s efforts, for
a period not less than 30 days following such notice (the “Cure Period”), to remedy the condition; (iv) notwithstanding such
efforts, the Good Reason condition continues to exist; and (v) the Executive provides a Notice of Termination to the Company
within 30 days after the end of the Cure Period.  If the Company cures the Good Reason condition during the Cure Period, Good
Reason shall be deemed not to have occurred.

4.

Change in Control Payment.  In the event a Terminating Event occurs on or within the 12 months

immediately after a Change in Control (such 12-month period, the “Change in Control Period”), subject to the Executive signing a
separation and release of claims agreement (the form of which will be provided by the Company on or promptly following the Date
of Termination (as defined in Section 10 below), and which shall contain, among other provisions, a general release of claims in
favor of the Company and related persons and entities, and confidentiality, return of property, non-disparagement, and 12-month
post-employment non-competition provisions (the “Separation Agreement”)) and such Separation Agreement becoming
irrevocable, all within 60 days (or such shorter period as the Company may specify) after the Date of Termination, the following
shall occur:

(a)

the Company shall pay to the Executive an amount equal to the sum of (i) 12 months of the

Executive’s annual base salary in effect immediately prior to the Terminating Event (or the Executive’s annual base
salary in effect immediately prior to the Change in Control, if higher), and (ii) a pro rata portion of the Executive’s target
bonus for the fiscal year in which the termination of employment occurs, determined by

 
 
 
multiplying the target bonus by a fraction, the numerator of which shall be the number of days during the fiscal year in
which the Executive was employed by the Company and the denominator of which shall be 365;

(b)

 If the Executive is eligible for and elects COBRA coverage, the Company shall pay, on the

Executive’s behalf or to the Executive, as determined by the Company, on a monthly basis, an amount equal to the share
of the premium for the Executive’s COBRA coverage that it paid immediately prior to the Date of Termination for the
Executive, until the earlier of (x) the date that is 12 months following the Date of Termination, or (y) the date that the
Executive becomes eligible to receive group health insurance coverage from another employer (as applicable, the
“COBRA Contribution Period”); provided, that the remaining balance of any premium costs during the COBRA
Contribution Period, and all premium costs thereafter, shall be paid by the Executive on a monthly basis for as long as,
and to the extent that, the Executive remains eligible for COBRA continuation, and further, that if the Executive becomes
eligible to receive group health insurance from another employer prior to the date that is 12 months following the Date of
Termination, the Executive  will provide written notice to the Company at least five (5) business days prior to such
eligibility date;

(c)

notwithstanding anything to the contrary in any applicable option agreement or stock-based award

agreement, all stock options and other stock-based awards with time-based vesting held by the Executive shall tentatively
accelerate and become fully vested, pending the Separation Agreement becoming irrevocable, upon the Date of
Termination, subject to compliance, if necessary, with Section 409A; provided, however, that the portion of each such
award for which vesting is so accelerated will only become fully vested and exercisable if and when the Separation
Agreement becomes irrevocable, and any such tentatively vested portion will be forfeited retroactively to the Executive’s
Date of Termination if the Executive either notifies the Company that the Executive will not execute or will revoke the
Separation Agreement, or the period for providing the Separation Agreement expires without the Executive signing and
returning the Separation Agreement, or the Executive revokes the Separation Agreement within the time set forth therein;
and

(d)

the amounts payable under Section 4(a) shall be paid out in a lump sum commencing within 60 days

after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and ends in a
second calendar year, the amounts shall be paid in the second calendar year on or before the last day of such 60-day
period.  All other wages earned through the Date of Termination (including, but not limited to, payment for accrued but
unused vacation) shall be paid on the Date of Termination.

5.

Severance Outside the Change in Control Period.  In the event a Terminating Event occurs at any time other

than during the Change in Control Period, subject to the Executive signing the Separation Agreement and such Separation
Agreement becoming irrevocable, all within 60 days (or such shorter period as the Company may specify) after the Date of
Termination, the following shall occur:

 
 
 
(a)

the Company shall pay to the Executive an amount equal to 12 months of the Executive’s annual base

salary in effect immediately prior to the Terminating Event;

(b)

If the Executive is eligible for and elects COBRA coverage, the Company shall pay, on the

Executive’s behalf, on a monthly basis, an amount equal to the share of the premium for the Executive’s COBRA
coverage that it pays for similarly situated active executives, until the earlier of (x) the date that is 12 months following
the Date of Termination, or (y) the date that the Executive becomes eligible to receive group health insurance coverage
from another employer (as applicable, the “COBRA Contribution Period”); provided, that the remaining balance of any
premium costs during the COBRA Contribution Period, and all premium costs thereafter, shall be paid by the Executive
on a monthly basis for as long as, and to the extent that, the Executive remains eligible for COBRA continuation, and
further, that if the Executive becomes eligible to receive group health insurance from another employer prior to the date
that is 12 months following the Date of Termination, the Executive  will provide written notice to the Company at least
five (5) business days prior to such eligibility date; and

(c)

the amounts payable under Section 5(a) shall be paid out in substantially equal installments in

accordance with the Company’s payroll practice over 12 months commencing within 60 days after the Date of
Termination; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year,
such amounts shall begin to be paid in the second calendar year on or before the last day of such 60-day period;
provided, further, that the initial payment shall include a catch-up payment to cover amounts retroactive to the day
immediately following the Date of Termination.  Each payment pursuant to this Agreement is intended to constitute a
separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2).

6.

Additional Limitation.

(a)

Anything in this Agreement to the contrary notwithstanding, in the event that the amount of any

compensation, payment or distribution by the Company to or for the benefit of the Executive, whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or otherwise, calculated in a manner consistent with
Section 280G of the Code and the applicable regulations thereunder (the “Compensatory Payments”), would be subject
to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”) (or any
successor provision), then the Compensatory Payments shall be reduced so that the sum of all of the Compensatory
Payments shall be $1.00 less than the amount at which the Executive becomes subject to the excise tax imposed by
Section 4999 of the Code (or any successor provision); provided that such reduction shall only occur if it would result in
the Executive receiving a higher After Tax Amount (as defined below) than the Executive would receive if the
Compensatory Payments were not subject to such reduction.  In such event, the Compensatory Payments shall be
reduced in the following order, in each case, in reverse chronological order beginning with the Compensatory Payments
that are to be paid the furthest in time from consummation of the transaction that is subject to Section 280G of the Code:
(i) cash payments not subject to Section 409A of the Code; (ii) cash payments subject to Section 409A of the Code; (iii)
equity-based payments and

 
 
 
acceleration; and (iv) non-cash forms of benefits; provided that in the case of all the foregoing Compensatory Payments
all amounts or payments that are not subject to calculation under Treas. Reg. §1.280G-1, Q&A-24(b) or (c) shall be
reduced before any amounts that are subject to calculation under Treas. Reg. §1.280G-1, Q&A-24(b) or (c).

(b)

For purposes of this Section 6, the “After Tax Amount” means the amount of the Compensatory

Payments less all federal, state, and local income, excise and employment taxes imposed on the Executive as a result of
the Executive’s receipt of the Compensatory Payments.  For purposes of determining the After Tax Amount, the
Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable
to individuals for the calendar year in which the determination is to be made, and state and local income taxes at the
highest marginal rates of individual taxation in each applicable state and locality, net of the maximum reduction in
federal income taxes which could be obtained from deduction of such state and local taxes.

(c)

The determination as to whether a reduction in the Compensatory Payments shall be made pursuant

to Section 6(a) shall be made by a law or accounting firm selected by the Company (the “Accounting Firm”), which shall
provide detailed supporting calculations both to the Company and the Executive within 15 business days of the Date of
Termination, if applicable, or at such earlier time as is reasonably requested by the Company or the Executive.  Any
determination by the Accounting Firm shall be binding upon the Company and the Executive.

7.

Section 409A.

(a)

Anything in this Agreement to the contrary notwithstanding, if at the time of the Executive’s

“separation from service” within the meaning of Section 409A of the Code, the Company determines that the Executive
is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or
benefit that the Executive becomes entitled to under this Agreement on account of the Executive’s separation from
service would be considered deferred compensation subject to the 20 percent additional tax imposed pursuant to Section
409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be
payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one day after the
Executive’s separation from service, and (B) the Executive’s death.

(b)

The parties intend that this Agreement will be administered in accordance with Section 409A of the

Code.  To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the
Code, the provision shall be read in such a manner so that all payments hereunder to be exempt from or to comply with
Section 409A of the Code.  

(c)

All in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be

provided by the Company or incurred by the Executive during the time periods set forth in this Agreement.  All
reimbursements shall be paid as

 
 
 
soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year
following the taxable year in which the expense was incurred.  The amount of in-kind benefits provided or reimbursable
expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for
reimbursement in any other taxable year.  Such right to reimbursement or in-kind benefits is not subject to liquidation or
exchange for another benefit.

(d)

To the extent that any payment or benefit described in this Agreement constitutes “non-qualified

deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon
the Executive’s termination of employment, then such payments or benefits shall be payable only upon the Executive’s
“separation from service.” The determination of whether and when a separation from service has occurred shall be made
in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-1(h).

(e)

The Company makes no representation or warranty and shall have no liability to the Executive or any

other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section
409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.

8.

Term.  This Agreement shall take effect on the date first set forth above and shall terminate upon the earlier of

(a) the termination of the Executive’s employment with the Company for any reason other than the occurrence of a Terminating
Event, or (b) the date all amounts have been paid to the Executive upon a Terminating Event pursuant to Section 4 or Section 5
hereof.

9.

Withholding.  All payments made by the Company to the Executive under this Agreement shall be net of any

tax or other amounts required to be withheld by the Company under applicable law.

10.

Notice and Date of Termination.

(a)

Notice of Termination. During the term of this Agreement, any purported termination of the

Executive’s employment (other than by reason of death) shall be communicated by written Notice of Termination from
one party hereto to the other party hereto in accordance with this Section 10.  For purposes of this Agreement, a “Notice
of Termination” shall mean a notice which shall indicate the specific termination provision in this Agreement relied
upon.

(b)

Date of Termination.  “Date of Termination” shall mean: (i) if the Executive’s employment is

terminated by the Executive’s death, the date of the Executive’s death; (ii) if the Executive’s employment is terminated
on account of the Executive’s Disability or by the Company with or without Cause, the date on which Notice of
Termination is given; (iii)  if the Executive’s employment is terminated by the Executive without Good Reason, 30 days
after the date on which a Notice of Termination is given, and (iv) if the Executive’s employment is terminated by the
Executive with Good Reason, the date on which a Notice of Termination is given after the end of the

 
 
 
Cure Period.  Notwithstanding the foregoing, in the event that the Executive gives a Notice of Termination to the
Company, the Company may unilaterally accelerate the Date of Termination and such acceleration shall not be deemed a
termination by the Company for purposes of this Agreement.

11.

No Mitigation.  The Company agrees that, if the Executive’s employment by the Company is terminated

during the term of this Agreement, the Executive is not required to seek other employment or to attempt in any way to reduce any
amounts payable to the Executive by the Company pursuant to Section 4 or Section 5 hereof.  Further, the amount of any payment
provided for in this Agreement shall not be reduced by any compensation earned by the Executive as the result of employment by
another employer.

12.

Scope of Disclosure Restrictions. Nothing in this Agreement or elsewhere prohibits the Executive from

communicating with government agencies about possible violations of federal, state, or local laws or otherwise providing
information to government agencies, filing a complaint with government agencies, or participating in government agency
investigations or proceedings.  The Executive is not required to notify the Company of any such communications; provided,
however, that nothing herein authorizes the disclosure of information the Executive obtained through a communication that was
subject to the attorney-client privilege.  Further, notwithstanding the Executive’s confidentiality and nondisclosure obligations, the
Executive is hereby advised as follows pursuant to the Defend Trade Secrets Act: “An individual shall not be held criminally or
civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that (A) is made (i) in confidence to a
Federal, State, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of
reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other
proceeding, if such filing is made under seal.  An individual who files a lawsuit for retaliation by an employer for reporting a
suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the
court proceeding, if the individual (A) files any document containing the trade secret under seal; and (B) does not disclose the trade
secret, except pursuant to court order.”

13.

Consent to Jurisdiction.  The parties hereby consent to the jurisdiction of the Superior Court of the

Commonwealth of Massachusetts and the United States District Court for the District of Massachusetts.  Accordingly, with respect
to any such court action, the Executive (a) submits to the personal jurisdiction of such courts; (b) consents to service of process;
and (c) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal jurisdiction
or service of process.

14.

Integration.  This Agreement, as well as the Offer Letter, the Agreement Concerning Loyalty, Confidential

Business Information, Inventions and Post-Employment Activity, and any applicable equity or other incentive agreements or plans,
constitute the entire agreement between the parties with respect to severance pay, benefits and accelerated vesting in connection
with any termination of employment, and, to the extent inconsistent with any prior agreements, supersedes the inconsistent
provisions of such prior agreements between the parties concerning such subject matter, including without limitation any
provisions of any offer letter or employment agreement relating to severance pay or benefits in connection with the ending of the
Executive’s employment relationship with the Company.  In the interest of clarity, any

 
 
 
agreement relating to confidentiality, non-competition, non-solicitation or assignment of inventions, including but not limited to the
Restrictive Covenants Agreement, shall not be affected by this Agreement.

15.

Successor to the Executive.  This Agreement shall inure to the benefit of and be enforceable by the

Executive’s personal representatives, executors, administrators, heirs, distributees, devisees and legatees.  In the event of the
Executive’s death after a Terminating Event but prior to the completion by the Company of all payments due to the Executive
under this Agreement, the Company shall continue such payments to the Executive’s beneficiary designated in writing to the
Company prior to the Executive’s death (or to the Executive’s estate, if the Executive fails to make such designation).

16.

Enforceability.  If any portion or provision of this Agreement (including, without limitation, any portion or

provision of any Section of this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those
as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this
Agreement shall be valid and enforceable to the fullest extent permitted by law.

17.

Waiver.  No waiver of any provision hereof shall be effective unless made in writing and signed by the

waiving party.  The failure of any party to require the performance of any term or obligation of this Agreement, or the waiver by
any party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a
waiver of any subsequent breach.

18.

Notices.  Any notices, requests, demands and other communications provided for by this Agreement shall be

sufficient if in writing and delivered in person or sent by a nationally recognized overnight courier service or by registered or
certified mail, postage prepaid, return receipt requested, to the Executive at the last address the Executive has filed in writing with
the Company, or to the Company at its main office, attention of the Board of Directors.

19.

Resignation of all Company Positions. No later than the Date of Termination, and prior to the provision or

payment of any benefits under this Agreement on account of such termination (except as required by law with respect to wages
earned through the Date of Termination), the Executive must resign from all positions that the Executive holds with the Company
unless otherwise requested by the Company.

20.

Amendment.  This Agreement may be amended or modified only by a written instrument signed by the

Executive and by a duly authorized representative of the Company.

21.

Effect on Other Plans and Agreements.  An election by the Executive to resign for Good Reason under the

provisions of this Agreement shall not be deemed a voluntary termination of employment by the Executive for the purpose of
interpreting the provisions of any of the Company’s benefit plans, programs or policies.  Nothing in this Agreement shall be
construed to limit the rights of the Executive under the Company’s benefit plans, programs or policies except as otherwise provided
in Section 6 hereof, and except that the Executive shall

 
 
 
have no rights to any severance benefits under any Company severance pay plan, offer letter, employment agreement or
otherwise.  In the event that the Executive is party to an agreement with the Company providing for payments or benefits under
such agreement and this Agreement, the terms of this Agreement shall govern and Executive may receive payment under this
Agreement only and not both.  Further, Section 4 and Section 5 of this Agreement are mutually exclusive and in no event shall
Executive be entitled to payments or benefits pursuant to both Section 4 and Section 5 of this Agreement.

22.

Governing Law.  This is a Massachusetts contract and shall be construed under and be governed in all
respects by the laws of the Commonwealth of Massachusetts, without giving effect to the conflict of laws principles of such
Commonwealth.  With respect to any disputes concerning federal law, such disputes shall be determined in accordance with the law
as it would be interpreted and applied by the United States Court of Appeals for the First Circuit.

23.

Successor to Company.  The Company shall require any successor (whether direct or indirect, by purchase,

merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company expressly to assume and
agree to perform this Agreement to the same extent that the Company would be required to perform it if no succession had taken
place.  Failure of the Company to obtain an assumption of this Agreement at or prior to the effectiveness of any succession shall be
a material breach of this Agreement.

24.

Counterparts.  This Agreement may be executed in any number of counterparts, each of which when so

executed and delivered shall be taken to be an original; but such counterparts shall together constitute one and the same document.

IN WITNESS WHEREOF, the parties have executed this Agreement effective on the date and year first above written.
