<b>1. Nature of Business</b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
Syndax Pharmaceuticals, Inc. (the “Company”) is a
clinical stage biopharmaceutical company developing entinostat as a
combination therapy in multiple cancer indications. Entinostat is
an oral, small molecule drug candidate that has direct effects on
both cancer cells and immune regulatory cells, potentially
enhancing the body’s immune response to tumors. Entinostat,
which was granted Breakthrough Therapy designation by the U.S. Food
and Drug Administration following positive results from the
Company’s Phase 2b clinical trial, ENCORE 301, is currently
being evaluated in a Phase 3 clinical trial for advanced hormone
receptor positive breast cancer. Concurrently, Syndax is developing
entinostat with a focus on tumors that have shown sensitivity to
immunotherapy, including lung cancer, melanoma, ovarian cancer and
triple-negative breast cancer (“TNBC”). The Company was
incorporated under the laws of the State of Delaware on
October 11, 2005 (date of inception) and is headquartered in
Waltham, Massachusetts.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
On March 8, 2016, the Company completed its initial public
offering (“IPO”) whereby it sold 4,400,000 shares of
common stock at the initial public offering price of $12.00 per
share. The aggregate net proceeds received by the Company from the
offering were $46.0 million, net of underwriting discounts and
commissions of $3.7 million and offering expenses of $3.1 million.
Upon the closing of the IPO, all outstanding shares of the
Company’s outstanding convertible preferred stock converted
into 12,872,551 shares of common stock; and the Company’s
outstanding warrant liability to purchase 357,840 shares of the
Company’s common stock valued at $4.6 million was
reclassified to additional paid-in capital. On March 11, 2016,
the Company issued and sold an additional 409,475 shares of its
common stock at the initial public offering price of $12.00 per
share as a result of the partial exercise by the underwriters of
their option to purchase additional shares of common stock,
resulting in additional net proceeds to the Company of $4.6
million, after deducting underwriting discounts and commissions of
$0.3 million. The shares began trading on the Nasdaq Global Select
Market on March 3, 2016 under the symbol
“SNDX.”</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In connection with the closing of the Company’s IPO, the
Company filed an amended and restated certificate of incorporation
and adopted amended and restated bylaws, both of which were
approved by the Company’s board of directors and stockholders
on September 28, 2015 and February 24, 2016,
respectively. Pursuant to the amended and restated certificate of
incorporation, the Company is now authorized to issue 100,000,000
of common stock and 10,000,000 shares of preferred stock.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
Since its inception, the Company has devoted its efforts
principally to research and development and raising capital. The
Company is subject to risks common to companies in the development
stage, including, but not limited to, successful development of
therapeutics, obtaining additional funding, protection of
proprietary therapeutics, compliance with government regulations,
fluctuations in operating results, dependence on key personnel and
collaborative partners, and risks associated with industry changes.
The Company’s long-term success is dependent upon its ability
to successfully develop and market entinostat, expand its oncology
drug pipeline, earn revenue, obtain additional capital when needed,
and ultimately, achieve profitable operations. The Company
anticipates that it will be several years before entinostat is
approved, if ever, and the Company begins to generate revenue from
sales of entinostat. Accordingly, management expects to incur
substantial losses on the ongoing development of entinostat and
does not expect to achieve positive cash flow from operations for
the foreseeable future, if ever. As a result, the Company will
continue to require additional capital to move forward with its
business plan. While certain amounts of this additional capital
were raised in the past, there can be no assurance that funds
necessary beyond these amounts will be available in amounts or on
terms sufficient to ensure ongoing operations.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
The Company’s management believes that the cash, cash
equivalents and short-term investments balances as of
March 31, 2016 should enable the Company to maintain its
planned operations for at least the next 12 months. The
Company’s ability to fund all of its planned operations
internally beyond that date, including the completion of its
ongoing and planned clinical trial activities may be substantially
dependent upon whether the Company can obtain sufficient funding on
terms acceptable to the Company. Proceeds from additional capital
transactions would allow the Company to accelerate and/or expand
its planned research and development activities. In the event that
sufficient funds were not available, the Company may be required to
delay or reduce expenditures to conserve cash, which could involve
scaling back or curtailing development and general and
administrative activities.</p>

<b>6. Fair Value Measurements</b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
The carrying amounts of cash and cash equivalents, restricted cash,
accounts payable, and accrued expenses approximated their estimated
fair values due to the short-term nature of these financial
instruments. Fair value is defined as the exchange price that would
be received for an asset or paid to transfer a liability (an exit
price) in the principal or most advantageous market for the asset
or liability in an orderly transaction between market participants
on the measurement date. Valuation techniques used to measure fair
value are performed in a manner to maximize the use of observable
inputs and minimize the use of unobservable inputs. The accounting
standard describes a fair value hierarchy based on three levels of
inputs, of which the first two are considered observable and the
last unobservable, that may be used to measure fair value, which
are the following:</p>

During the periods presented, the Company has not changed the
manner in which it values assets and liabilities that are measured
at fair value using Level 3 inputs. The Company recognizes
transfers between levels of the fair value hierarchy as of the end
of the reporting period. There were no transfers within the
hierarchy for any of periods presented.</p>

Cash equivalents of $18.4 million as of March 31, 2016 and
$9.2 million as of December 31, 2015 consisted of money
market funds and are classified within Level 1 of the fair value

active markets. Cash equivalents of $3.5 million as of
March 31, 2016 and $13.9 million as of December 31,
2015 consisted of highly rated corporate bonds and are classified
within Level 2 of the fair value hierarchy because pricing inputs
are other than quoted prices in active markets, which are either
directly or indirectly observable as of the reporting date, and

The short-term investments are classified as available-for-sale
securities. As of March 31, 2016, the remaining contractual
maturities of the available-for-sale securities were less than one
year, and the balance in the Company’s accumulated other
comprehensive income was comprised solely of activity related to
the Company’s available-for-sale securities. There were no
realized gains or losses recognized on the sale or maturity of
available-for-sale securities during the three months ended
March 31, 2016 and 2015; and as a result, the Company did not
reclassify any amounts out of accumulated other comprehensive
income for the same periods. The Company has a limited number of
available-for-sale securities in insignificant loss positions as of
March 31, 2016, which the Company does not intend to sell and
has concluded it will not be required to sell before recovery of
the amortized cost for the investment at maturity. The following
table summarizes the available-for-sale securities:</p>

The common stock warrant liability was recorded at fair value
determined by using the Black-Scholes option-pricing model. This
method of valuation involves using inputs such as the fair value of
the Company’s common stock, stock price volatility, the
contractual term of the warrant, risk-free interest rates, and
dividend yields. Due to the nature of these inputs, the valuation
of the warrants was considered a Level 3 measurement. Upon the
closing of the IPO, the warrant was reclassified to additional
paid-in capital. See Note 5 for further discussion of the
accounting for the Bayer common stock warrant as well as for a
summary of the significant inputs and assumptions used to determine
the fair value of the warrant.</p>

The derivative liability related to the contingent success fee owed
under the term loans. Upon the completion of an IPO or upon the
occurrence of certain change of control or liquidation events, the
Company is required to pay a $0.2 million success fee. The Company
had recorded the success fee as a derivative financial liability.
The initial fair value of the derivative of $0.1 million had been
recorded as a debt discount. The term loans were paid in full in
October 2015; however, the liability for the success fee survived
the repayment of the term loans. Upon completion of the IPO this is
no longer accounted for as a derivative, and the success fee of
$0.2 million that is payable in June 2018 is included in other
long-term liabilities.</p>

The Company has not recorded any net tax provision for the periods

<i>Use of Estimates</i> – The preparation of condensed
consolidated financial statements in conformity with U.S. 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 condensed
consolidated financial statements and the reported amounts of costs
and expenses during the reporting period. The Company bases
estimates and assumptions on historical experience when available
and on various factors that it believes to be reasonable under the
circumstances. The Company evaluates its estimates and assumptions
on an ongoing basis. The Company’s actual results may differ
from these estimates under different assumptions or conditions.</p>

<b>10. Stock-Based Compensation</b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
In September 2015, the Company’s board of directors adopted
its 2015 Omnibus Incentive Plan (“2015 Plan”), which
was subsequently approved by its stockholders and became effective
upon the closing of the IPO on March 8, 2016. The 2015 Plan
replaces the 2007 Stock Plan (“2007 Plan”). The 2015
Plan allows for the granting of incentive stock options,
nonqualified stock options, stock appreciate rights, restricted
stock, unrestricted stock, stock units, dividend equivalent rights,
performance awards, annual incentive awards, and other equity-based
awards to the Company’s executives and other employees,
non-employee members of the board of directors, and consultants of
the Company. Any options or awards outstanding under the
Company’s 2007 Plan remain outstanding and effective. Any
shares of common stock related to awards outstanding under the 2007
Plan which thereafter terminate by expiration, forfeiture,
cancellation or otherwise without the issuance of such shares will
be added to, and included in, the 2015 Plan reserve amount. The
Company initially reserved 1,750,000 shares of its common stock for
the issuance of awards under the 2015 Plan. The 2015 Plan provides
that the number of shares reserved and available for issuance under
the 2015 Plan will automatically increase each January 1,
beginning on January 1, 2017, by 4% of the outstanding number
of shares of common stock on the immediately preceding
December 31 or such lesser number of shares as determined by
the Company’s board of directors. As of March 31, 2016,
there were 1,750,000 shares available for issuance under the 2015
Plan.</p>

During the three months ended March 31, 2016, the Company
granted 150,480 stock options to certain executives and employees.
The grant date fair value of these options was $1.0 million, or
$6.82 per share on a weighted-average basis, and will be recognized
as compensation expense over the requisite service period of three
to four years.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
Upon the closing of the IPO on March 8, 2016, the vesting of
certain options granted to two of the Company’s executives
immediately vested, in accordance with their employment agreements.
The Company recorded $0.7 million of additional stock compensation
expense related to this accelerated vesting in March 2016.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
As of March 31, 2016, there was $7.9 million of unrecognized
compensation cost related to employee and non-employee unvested
stock options and unvested restricted stock share-based
compensation arrangements granted under the 2007 Plan, which is
expected to be recognized over a weighted-average remaining service
period of 2.8 years. Stock compensation costs have not been
capitalized by the Company.</p>

In May 2014, the Financial Accounting Standards Board (the
“FASB”) issued Accounting Standards Update
(“ASU”) 2014-09, <i>Revenue from Contracts with
Customers</i> (“ASU 2014-09”). ASU 2014-09 supersedes
the revenue recognition requirements of the FASB’s Accounting
Standards Codification (“ASC”) Topic 605, <i>Revenue
Recognition,</i> and most industry-specific guidance throughout the
ASC, resulting in the creation of FASB ASC Topic 606, <i>Revenue
from Contracts with Customers</i>. ASU 2014-09 requires entities to
recognize revenue in a way that depicts the transfer of promised
goods or services to customers in an amount that reflects the
consideration to which the entity expects to be entitled to in
exchange for those goods or services. In March 2016, the FASB
issued ASU 2016-08, <i>Revenue from Contracts with Customers (Topic
606): Principal versus Agent Considerations (Reporting Revenue
Gross versus Net),</i> (“ASU 2016-08”), which amends
ASU 2014-09 to clarify the implementation guidance on principal
versus agent considerations (gross versus net revenue
presentation). ASU 2016-08 does not change the core principle of
the guidance stated in ASU 2014-09, instead, the amendments in this
ASU are intended to improve the operability and understandability
of the implementation guidance on principal versus agent
considerations and whether an entity reports revenue on a gross or
net basis. Adoption of both ASU 2016-08 and 2014-09 will be
permitted using either a retrospective or modified retrospective
approach. In July 2015, the FASB voted to delay the effective date
of the standard by one year to the first quarter of 2018 to provide
companies sufficient time to implement the standard. The collective
guidance will be effective for the Company on January 1, 2018,
with early adoption permitted but not before January 1, 2017.
The Company is currently evaluating the method by which it will
implement these standards and the impact of the adoption of these
standards on the Company’s condensed consolidated financial
statements.</p>

In February 2016, the FASB issued ASU 2016-02, “<i>Leases
(Topic 842)</i>.” Under ASU 2016-02, lessees will be required
to recognize, for all leases of 12 months or more, a liability to
make lease payments and a right-of-use asset representing the right
to use the underlying asset for the lease term. Additionally, the
guidance requires improved disclosures to help users of financial
statements better understand the nature of an entity’s
leasing activities. This ASU is effective for public reporting
companies for interim and annual periods beginning after
December 15, 2018, with early adoption permitted, and must be
adopted using a modified retrospective approach. The Company is in
the process of evaluating the effect of the new guidance on its
condensed consolidated financial statements and disclosures.</p>

simplifies several aspects related to the accounting for

<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
<i>Significant Accounting Policies</i><b>—</b>The
Company’s significant accounting policies are disclosed
in the audited consolidated financial statements for the year ended
December 31, 2015 and the notes thereto, which are included in
the Prospectus, have had no material changes during the three
months ended March 31, 2016.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
<i>Use of Estimates</i> – The preparation of condensed
consolidated financial statements in conformity with U.S. 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 condensed
consolidated financial statements and the reported amounts of costs
and expenses during the reporting period. The Company bases
estimates and assumptions on historical experience when available
and on various factors that it believes to be reasonable under the
circumstances. The Company evaluates its estimates and assumptions
on an ongoing basis. The Company’s actual results may differ
from these estimates under different assumptions or conditions.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
<i>Other Assets</i> – Other assets consist of deferred
issuance costs, long-term security deposits and noncurrent
restricted cash. Deferred issuance costs consist primarily of
direct incremental legal and accounting fees relating to the IPO
and issuance of debt. As of March 31, 2016 and
December 31, 2015, the Company had capitalized deferred IPO
issuance costs of $0 and $1.6 million, respectively. These costs
were deferred until the completion of the IPO, at which time they
were reclassified to additional paid-in capital as a reduction of
the IPO proceeds.</p>

Basic net loss attributable to common stockholders per share is
computed by dividing the net loss attributable to common
stockholders by the weighted-average number of common shares
outstanding for the period. Because the Company has reported a net

is the same as basic net loss per common share for those periods.

<b>Merck KGaA – Pfizer Collaboration</b> – On
December 31, 2015, the Company entered into a clinical trial
collaboration and supply agreement with Ares Trading, S.A., a
subsidiary of Merck KGaA, Darmstadt, Germany, and Pfizer Inc. (the
“Alliance”) under which it will conduct a clinical
trial evaluating entinostat in combination with an investigational
monoclonal antibody, avelumab, in patients with ovarian cancer.
Avelumab is being developed collaboratively by the Alliance, which
are together treated as a single party for purposes of this
agreement. The Company will be the sponsor of the clinical trial.
The Alliance will supply avelumab for use in the clinical trial.
During the term of the trial or the term of the agreement,
whichever is shorter, each party has agreed not to initiate any
clinical trial in combination with such party’s drug and a
third party drug for the treatment of ovarian cancer if the third
party drug has the same target and mechanism of action as the other
party’s drug, subject to certain exceptions. To the extent
any inventions arise from the clinical trial, each party will
solely own inventions relating to its drug alone, and the parties
will jointly own any inventions relating to the combination of the
two drugs. In most cases, data from the trial will be jointly
owned. However, each party will solely own certain sample analysis
data generated from clinical samples obtained from trial
participants. Either party may terminate the agreement for the
other party’s uncured material breach. In addition, either
party may terminate the agreement if it determines that the trial
may unreasonably affect patient safety, or if a regulatory
authority takes an action that prevents such party from supplying
its drug, or if such party decides to discontinue development of
its drug. The Alliance may also terminate the agreement if the
Company fails to make any changes to the clinical trial protocol
that are reasonably requested by the Alliance to address a
perceived safety issue.</p>

<b>Kyowa Hakko Kirin Co., Ltd. –</b> On December 19,
2014 (the “Effective Date”), the Company entered into a
license agreement (the “KHK License Agreement”) with
Kyowa Hakko Kirin Co., Ltd. (“KHK”), under which the
Company granted KHK an exclusive license to develop and
commercialize entinostat in Japan and Korea. Under the terms of the
KHK License Agreement, the Company will be responsible for the
manufacture and supply of the products during the development
activities. In addition to the license and manufacturing
obligations, the Company is obligated to provide KHK access to
know-how and regulatory information the Company may develop over
the life of the entinostat patent. To the extent additional
intellectual property is developed during the term of the
agreement, KHK will receive a license to the intellectual property
when and if available. KHK will conduct the development, regulatory
approval filings, and commercialization activities of entinostat in
Japan and Korea. KHK paid the Company $25.0 million upfront, which
included a $7.5 million equity investment of 536,049 shares of
Series B-1 convertible preferred stock and a $17.5 million
non-refundable cash payment. In addition, to the extent certain
development and commercial milestones are achieved, KHK will be
required to pay the Company up to $75.0 million in milestone
payments over the term of the license agreement. Unless terminated
earlier in accordance with the terms of the agreement, it will
continue on a country-by-country and product-by-product basis,
until the later of: (i) the date all valid claims of the last
effective patent among the Company’s patents expires or is
abandoned, withheld, or is otherwise invalidated in such country;
and (ii) 15 years from the date of the first commercial sale
of a product in the Japan or Korea.</p>

The purchase of the Series B-1 and the upfront payment of the
license fee were accounted for separately. The Company allocated
the amount of consideration related to Series B-1 equal to the fair
value of the Series B-1 shares on the Effective Date based on a
share price of $14.39 per share, which resulted in $7.7 million of
proceeds allocated to the Series B-1 and the remaining
consideration of $17.3 million allocated to the upfront license
fee. The fair value of the Series B-1 of $14.39 per share was based
on a contemporaneous valuation. The Company received $7.5 million
and issued the Series B-1 in January 2015 and received the
remaining $17.5 million in February 2015. On the date of issuance,
the Company recorded accretion of $5.4 million to record the Series
B-1 at its redemption value.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%">
The Company has concluded that this agreement is within the scope
of ASC 605-25, <i>Revenue Recognition, Multiple-Element
Arrangements</i>. Pursuant to this guidance, the Company identified
the following deliverables: (i) licenses; (ii) clinical
supply and manufacturing obligations; (iii) rights to access
and use materials and data; and (iv) rights to additional
intellectual property. All other potential deliverables included in
the arrangement have been deemed either contingent or
inconsequential or perfunctory, individually and in the aggregate.
Moreover, the Company has evaluated all deliverables included in
the KHK License Agreement and determined that there are two units
of accounting in connection with its obligations at inception under
the KHK License Agreement: (i) license unit of accounting and
(ii) rights to additional intellectual property. The first
three deliverables identified above comprise the license unit of
accounting. The Company concluded that the stand-alone selling
price for the rights to additional intellectual property unit of
account is immaterial. As such, the entire $17.3 million allocated
to the upfront payment will be allocated to the license unit of
accounting. The arrangement consideration allocated to the license
unit of accounting will be recognized as revenue ratably over the
Company’s expected services period (currently expected to be
through 2029) commencing on the date of the first delivery of the
clinical trial materials.</p>

<b>Eastern Cooperative Oncology Group</b> – In March 2014,
the Company entered into a clinical trial agreement (the
“ECOG Agreement”) with Eastern Cooperative Oncology
Group, a contracting entity for the Eastern Cooperative Oncology
Group—American College of Radiology Imaging Network Cancer
Research Group (“ECOG-ACRIN”), that describes the
parties’ obligations with respect to the NCI-sponsored
pivotal Phase 3 clinical trial of entinostat. Under the terms of
the ECOG Agreement, ECOG-ACRIN will perform this clinical trial in
accordance with the clinical trial protocol and a mutually agreed
scope of work. The Company will provide a fixed level of financial
support for the clinical trial through an upfront payment of
$695,000 and a series of payments of up to $1.0 million each
that are comprised of milestone payments through the completion of
enrollment and time-based payments through the completion of
patient monitoring post-enrollment. In addition, the Company is
obligated to supply entinostat and placebo to ECOG-ACRIN for use in
the clinical trial. As of March 31, 2016, the Company’s
aggregate payment obligations under this agreement were
approximately $20.6 million; and the Company’s remaining
payment obligations are approximately $17.6 million over an
estimated period of approximately five years. In April 2016, the
ECOG Agreement was amended to provide additional study activities
and the contractual obligation increased $0.5 million.</p>

Data and inventions from the Phase 3 clinical trial are owned by
ECOG-ACRIN. The Company has access to the data generated in the
clinical trial, both directly from ECOG-ACRIN under the ECOG
Agreement as well as from the NCI. Additionally, ECOG-ACRIN has
granted the Company a non-exclusive royalty-free license to any
inventions or discoveries that are derived from entinostat as a
result of its use during the clinical trial, along with a first
right to negotiate an exclusive license to any of these inventions
or discoveries. Either party may terminate the ECOG Agreement in
the event of an uncured material breach by the other party or if
the FDA or NCI withdraws the authorization to perform the clinical
trial in the United States. The parties may jointly terminate the
ECOG Agreement if the parties agree that safety-related issues
support termination of the clinical trial.</p>

The Company records the appropriate clinical trial expenses in its
financial statements by matching those expenses with the period in
which the services and efforts are expended. The Company accounts
for these expenses according to the progress of the clinical trial
as measured by patient enrollment and the timing of various aspects
of the clinical trial. The Company determines accrual estimates
through financial models, taking into account discussion with
applicable personnel and ECOG-ACRIN as to the progress or state of
consummation of the clinical trial or the services completed.</p>

<b>Bayer Pharma AG (formerly known as Bayer Schering Pharma AG)</b>
– In March 2007, the Company entered into a license agreement
(the “Bayer Agreement”) with Bayer Schering Pharma AG
(“Bayer”) for a worldwide, exclusive license to develop
and commercialize entinostat and any other products containing the
same active ingredient. Under the terms of the Bayer Agreement, the
Company paid a nonrefundable upfront license fee of $2.0 million
and is responsible for the development and marketing of entinostat.
The Company recorded the $2.0 million license fee as research and
development expense during the year ended December 31, 2007,
as it had no alternative future use. The Company will pay Bayer
royalties on a sliding scale based on net sales, if any, and make
future milestone payments to Bayer of up to $150.0 million in the
event that certain specified development and regulatory goals and
sales levels are achieved. In June 2014, a development milestone
was achieved, and the Company recorded $2.0 million of research and
development expense, which has been fully paid.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%">
In connection with the Bayer Agreement, the Company issued to Bayer
a warrant to purchase the number of shares of the Company’s
common stock equal to 1.75% of the shares of common stock
outstanding on a fully diluted basis as of the earlier of the date
the warrant is exercised or the closing of the IPO. The warrant
contains anti-dilution protection to maintain Bayer’s
potential ownership at 1.75% of the shares of common stock
outstanding on a fully diluted basis, which requires that the
actual number of shares of common stock issuable pursuant to the
warrant be increased or decreased for any changes in the fully
diluted shares of common stock outstanding. The warrant is
exercisable at an exercise price of $1.54 per share and expires
upon the earlier of the 10-year anniversary of the closing of the
IPO or the date of the consummation of a disposition transaction.
The warrant was classified as a long-term liability and recorded at
fair value with the changes in the fair value recorded in other
expense. The Company used the Black-Scholes option-pricing model to
determine the fair value of the warrant. Upon the closing of the
IPO, the anti-dilution protection for the warrant expired,
resulting in the reclassification of the warrant liability to
additional paid-in capital. The warrant was re-measured using
current assumptions just prior to the reclassification.</p>

<p><em>Other Assets</em> – Other assets consist of deferred
issuance costs, long-term security deposits and noncurrent
restricted cash. Deferred issuance costs consist primarily of
direct incremental legal and accounting fees relating to the IPO
and issuance of debt. As of March 31, 2016 and
December 31, 2015, the Company had capitalized deferred IPO
issuance costs of $0 and $1.6 million, respectively. These costs
were deferred until the completion of the IPO, at which time they
were reclassified to additional paid-in capital as a reduction of
the IPO proceeds.</p>
