<b><i>Stock-Based Compensation</i></b></p>
<p style="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
The Company recognizes compensation expense for all share-based
payment awards made to employees and directors based on estimated
fair values. For employee stock options, the Company determines the
grant date fair value of the awards using the Black-Scholes
option-pricing model and generally recognizes the fair value as
stock-based compensation expense on a straight-line basis over the
vesting period of the respective awards. Stock-based compensation
expense is based on the value of the portion of stock-based payment
awards that is ultimately expected to vest. As such, the
Company’s stock-based compensation is reduced for the
estimated forfeitures at the date of grant and revised, if
necessary, in subsequent periods if actual forfeitures differ from
those estimates. For restricted stock, the compensation cost for
these awards is based on the closing price of the Company’s
common stock on the date of grant and recognized as compensation
expense on a straight-line basis over the requisite service
period.</p>
<p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
The Company accounts for equity instruments issued to nonemployees
based on their fair values on the measurement dates using the
Black-Scholes option-pricing model. The estimated fair values of
the options granted to nonemployees are remeasured as they vest. As
a result, the noncash charge to operations for nonemployee options
with vesting conditions is affected each reporting period by
changes in the fair value of the Company’s common stock.</p>

Financial instruments that potentially subject the Company to
significant concentrations of credit risk consist primarily of
cash, cash equivalents and short-term investments. The Company is
exposed to credit risks in the event of default by the issuers to
the extent of the amount recorded in its Consolidated Balance
Sheets. Cash, cash equivalents and short-term investments are

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
must maximize the use of observable inputs and minimize the use of
unobservable inputs.</p>

The Company granted options under its 2008 Stock Incentive Plan
(the “2008 Plan”) until June 2014 when it was
terminated as to future awards, although it continues to govern the
terms of options that remain outstanding under the 2008 Plan. The
2008 Plan provided for the granting of incentive and nonstatutory
stock options, and stock purchase rights to employees, directors
and consultants at the discretion of the Board of Directors. Stock
options granted generally vest over a period of four years from the
date of grant. In connection with the Board of Directors and
stockholders’ approval of the 2014 Plan, all remaining shares
available for future award under the 2008 Plan were transferred to
2014 Plan, and the 2008 Plan was terminated.</p>

The 2014 Equity Incentive Award Plan (“2014 Plan”)
became effective on June 18, 2014, immediately prior to the
time the Company’s Registration Statement on Form <font style="WHITE-SPACE: nowrap">S-1</font> became effective. Under the
2014 Plan, 1,419,328 shares of common stock were initially reserved
for issuance pursuant to a variety of stock-based compensation
awards, including stock options, stock appreciation rights, or
SARs, restricted stock awards, restricted stock unit (RSU) awards,
deferred stock awards, deferred stock unit awards, dividend
equivalent awards, stock payment awards and performance awards. In
addition, 35,221 shares that had been available for future awards
under the 2008 Plan as of June 18, 2014, were added to the
initial reserve available under the 2014 Plan, bringing the total
reserve upon the effective date of the 2014 Plan to 1,454,549. The
number of shares initially reserved for issuance or transfer
pursuant to awards under the 2014 Plan will be increased by
(i) the number of shares represented by awards outstanding
under 2008 Plan on June 18, 2014, that are either forfeited or
lapse unexercised or that are repurchased for the original purchase
price thereof, up to a maximum of 1,153,279 shares, and
(ii) if approved by the Administrator of the 2014 Plan, an
annual increase on the first day of each fiscal year ending in
2024, equal to the lesser of (A) four percent (4.0%) of the
shares of stock outstanding (on an as converted basis) on the last
day of the immediately preceding fiscal year and (B) such
smaller number of shares of stock as determined by our board of
directors; provided, however, that no more than 10,683,053 shares
of stock may be issued upon the exercise of incentive stock
options. Effective January 1, 2017, the 2014 Plan share
reserve was increased by 1,892,376 shares.</p>

The Company adopted the 2014 Employee Stock Purchase Plan (ESPP)
and initially reserved 202,762 shares of common stock as of its
effective date of June 18, 2014. If approved by the
Administrator of the ESPP, on the first day of each calendar year,
ending in 2024, the number of shares in the reserve will increase
by an amount equal to the lesser of (i) one percent (1.0%) of
the shares of common stock outstanding on the last day of the
immediately preceding fiscal year and (ii) such number of
shares of common stock as determined by the board of directors;
provided, however, no more than 2,230,374 shares of our common
stock may be issued under the ESPP. Effective January 1, 2015,
the ESPP share reserve was increased by 185,892. Under the ESPP,
participants are offered the option to purchase shares of the
Company’s common stock at a discount during a series of
successive offering periods normally commencing on March 1 and
September 1 of each year. The initial offering period
commenced on September 1, 2014 and will end on
February 27, 2015. As of December 31, 2016 278,020 shares
were available for future issuance under the ESPP.</p>

During September 2014, the Company entered into a Transition and
Separation Agreement with its Chief Scientific Officer, Dominique
Charmot, under which certain restricted shares that were subject to
vesting and repurchase by the Company have become fully vested as
of Dr. Charmot’s separation from the Company as an
employee and director on December 23, 2014. This resulted in
the acceleration of the vesting for 58,969 shares of restricted
stock. As a result of the acceleration, the Company has recorded a
stock-based compensation charge of $0.8 million during the
year ended December 31, 2014 to reflect the revised service
period for the restricted stock and related vesting of shares that
would otherwise not have vested.</p>

In June 2015, the Company sold and issued an aggregate of 7,242,992
shares of its common stock and warrants to purchase 2,172,899
shares of common stock for aggregate gross proceeds of
approximately $77.8 million or net proceeds, after deducting
issuance costs, of approximately $74.3 million. The purchase
price for the common stock was $10.70 per share and the purchase
price for the warrants was $0.125 per warrant. The warrants are
exercisable for an exercise price of $13.91 per share at any time
prior to the earlier of (i) 5 years from the date of issuance or
(ii) certain changes in control of the Company. The Company
has determined that the warrants should be classified as equity. In
July 2015, the Company filed a registration statement with the SEC
with respect to the common stock and warrants.</p>

Other than with respect to warrants issued to holders affiliated
with New Enterprise Associates, the warrants contain limitations
that prevent each holder of warrants from acquiring shares upon
exercise of the warrants that would cause the number of shares
beneficially owned by it and its affiliates to exceed 9.99% of the
total number of shares of the Company’s common stock then
issued and outstanding. In addition, upon certain changes in
control of the Company, each holder of a warrant can elect to
receive, subject to certain limitations and assumptions, securities
in a successor entity. None of the warrants issued in June 2015
have been exercised during each of the years ended
December 31, 2015 and December 31, 2016.</p>

The Company has granted options to purchase shares of common stock
to consultants in exchange for services performed. The Company
granted options to purchase 12,500, 5,000 and 10,000 shares with
average exercise prices of $13.71, $18.58 and $20.77 per share,
respectively, during the years ended December 31, 2016, 2015
and 2014, respectively. These options vest upon grant or various
terms up to three years. The Company recognized <font style="WHITE-SPACE: nowrap">non-employee</font> stock compensation expense of
$0.1 million, $0.2 million and $0.1 million during
the years ended December 31, 2016, 2015 and 2014,
respectively. Compensation expense for <font style="WHITE-SPACE: nowrap">non-employee</font> stock options is calculated
using the Black-Scholes option-pricing model and is recorded as the
options vest. Options subject to vesting are required to be
periodically revalued over their service period, which is generally
the same as the vesting period.</p>

Basic net loss per common share is calculated by dividing the net
loss by the weighted-average number of common shares outstanding
during the period, without consideration of common stock
equivalents. Diluted net loss per common share in the periods
presented is the same as basic net loss per common share, since the
effects of potentially dilutive securities are antidilutive.</p>

During the three months ended December 31, 2016, the Company
determined that one of its bank accounts comprising $24.0 million
at December 31, 2015 should have been classified as cash
rather than as money market funds. Accordingly, the impact of this
reclassification has been reflected in the table for
December 31, 2015 presented above. The Company made a similar
reclassification in <b>NOTE 4, FAIR VALUE
MEASUREMENTS</b>. This change in classification does not affect
previously reported financial statements for any period.</p>

Cash equivalents consist of money market funds and corporate
debt securities with original maturities of three months or less at
the time of purchase, and the carrying amount is a reasonable
approximation of fair value. The Company invests its cash in high
quality securities of financial and commercial institutions. These
securities are carried at fair value, which is based on readily
available market information, with unrealized gains and losses
included in “accumulated other comprehensive loss”
within stockholders’ equity on the Company’s
consolidated balance sheets. The Company uses the specific
identification method to determine the amount of realized gains or
losses on sales of marketable securities. For the year ended
December 31, 2016, there were no realized gains or losses on
the <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">available-for-sale</font></font> securities.</p>

All <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">available-for-sale</font></font> securities held as of
December 31, 2016 had contractual maturities of less than one
year. Investments that have maturities beyond one year as of the
end of the reporting period are classified as <font style="WHITE-SPACE: nowrap">non-current.</font> The
Company’s <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">available-for-sale</font></font> securities
are subject to a periodic impairment review. The Company considers
a debt security to be impaired when its fair value is less than its
carrying cost, in which case the Company would further review the
investment to determine whether it is other-than-temporarily
impaired. When the Company evaluates an investment for
other-than-temporary impairment, the Company reviews factors such
as the length of time and extent to which fair value has been below
cost basis, the financial condition of the issuer and any changes
thereto, intent to sell, and whether it is more likely than not the
Company will be required to sell the investment before the recovery
of its cost basis. If an investment is other-than-temporarily
impaired, the Company writes it down through the statement of
operations to its fair value and establishes that value as a new
cost basis for the investment. The Company did not identify any of
its <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">available-for-sale</font></font> securities as
other-than-temporarily impaired in any of the periods presented. As
of December 31, 2016, no investment was in a continuous
unrealized loss position for more than one year, the unrealized
losses were not due to a change in credit risk and the Company
believes that is more likely than not the investments will be held
until maturity or a forecasted recovery of fair value.</p>

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
must maximize the use of observable inputs and minimize the use of
unobservable inputs.</p>

Where quoted prices are available in an active market, securities
are classified as Level 1. The Company classifies money market
funds as Level 1. When quoted market prices are not available
for the specific security, then the Company estimates fair value by
using benchmark yields, reported trades, broker/dealer quotes, and
issuer spreads. The Company classifies certificates of deposit as
Level 2. In certain cases, where there is limited activity or
less transparency around inputs to valuation, securities are
classified as Level 3. There were no transfers between

The Company has a lease agreement for a facility in Fremont,
California that was amended in December 2012 to extend the lease
agreement to September 2016. In September 2014, the Company signed
the second amendment to its facility lease agreement in Fremont,
California to add space and to extend the lease term through
September 2019. In addition, the amended lease agreement provides
for a tenant improvement allowance of up to $0.6 million. In
May 2016, the Company signed a third amendment to its facility
lease agreement in Fremont, California to add space and to extend
the lease term through September 2021 (the “Third
Amendment”). The Third Amendment provides for a tenant
improvement allowance of up to $0.4 million and the extended
lease has rent escalation clauses throughout the lease term. Rent
increases, including the impact of a rent holiday and leasehold
improvement allowance from the landlord, will be recognized as
deferred rent and amortized on a straight-line basis over the term
of the lease.</p>

The Company indemnifies each of its officers and directors for
certain events or occurrences, subject to certain limits, while the
officer or director is or was serving at our request in such
capacity, as permitted under Delaware law and in accordance with
our certificate of incorporation and bylaws. The term of the
indemnification period lasts as long as an officer or director may
be subject to any proceeding arising out of acts or omissions of
such officer or director in such capacity.</p>

The maximum amount of potential future indemnification is
unlimited; however, the Company currently holds director and
officer liability insurance. This insurance allows the transfer of
risk associated with our exposure and may enable the Company to
recover a portion of any future amounts paid. The Company believes
that the fair value of these indemnification obligations is
minimal. Accordingly, the Company has not recognized any
liabilities relating to these obligations for any period
presented.</p>

Basic net loss per share is calculated by dividing net loss by the
weighted-average number of common shares outstanding during the
period, less shares subject to repurchase, and excludes any
dilutive effects of share-based awards and warrants. Diluted net
loss per common share is computed giving effect to all potential
dilutive common shares, including common stock issuable upon
exercise of stock options, and unvested restricted common stock and
stock units. As the Company had net losses for the years ended
December 31, 2016, 2015 and 2014, all potential common shares
were determined to be anti-dilutive. The following table sets forth
the computation of net loss per common share (in thousands, except
share and per share amounts):</p>

In October 2012, the Company entered into a collaboration
partnership with AstraZeneca for the worldwide development and
commercialization of tenapanor. Under the terms of the AstraZeneca
collaboration partnership agreement, or the AstraZeneca Agreement,
the Company received an aggregate of $75 million in
<font style="WHITE-SPACE: nowrap">up-front</font> license and
milestone fees. The amounts were recorded as deferred revenue when
received and were recognized as revenue on a straight-line basis
over the remaining estimated period of performance under the
AstraZeneca Agreement.</p>

product candidate, tenapanor, were terminated, except for the
limited purpose of allowing AstraZeneca to satisfy its obligations
under the Termination Agreement. As the AstraZeneca Agreement was
terminated in June 2015, the Company recognized the remaining
deferred revenue balance of $43.1 million during the three
months ended June 30, 2015. In the three months ended
June 30, 2015, the Company recorded a $15.0 million
payment for the return of the licenses as well as a
$10.0 million payment for reimbursement of research and
development expenses and the acceleration of the transfer of
information and materials as a reduction in licensing revenue in
the consolidated statements of operations. There has been no

In February 2014, the Company entered into a license option and
license agreement with Sanofi (the “Sanofi Agreement”)
for its phosphate transport NaP2b inhibitor program. Under the
terms of the Sanofi Agreement, the Company granted Sanofi an
exclusive worldwide license to conduct research utilizing the
Company’s small molecule NaP2b inhibitors. In addition,
Sanofi had the option to obtain an exclusive license to develop,
manufacture and commercialize potential products under the
agreement. Under the Sanofi Agreement, the Company received a
payment of $1.25 million in March 2014, which was fully
recognized as licensing revenue in May 2014 after the Company
completed its obligation to provide to Sanofi the background

The Company assesses the available positive and negative evidence
to estimate whether sufficient future taxable income will be
generated to permit use of the existing deferred tax assets. A
significant piece of objective negative evidence evaluated was the
cumulative loss incurred over the <font style="WHITE-SPACE: nowrap">two-year</font> periods ended
December 31, 2016 and December 31, 2015. Such objective
evidence limits the ability to consider other subjective evidence,
such as our projections for future growth. On the basis of this
evaluation, as of December 31, 2016 and December 31,
2015, full valuation allowance has been recorded against
Company’s net deferred tax asset. The amount of the deferred
tax asset considered realizable, however, could be adjusted if
estimates of future taxable income during the carryforward period
are reduced or increased or if objective negative evidence in the
form of cumulative losses is no longer present and additional
weight is given to subjective evidence such as our projections for
growth. The valuation allowance increased by approximately
$40.7 million for the year ended December 31, 2016. The
valuation allowance increased by approximately $9.1 million
for the year ended December 31, 2015.</p>

approximately $3.4 million that expire beginning in 2027 if
not utilized. In addition, the Company had net operating loss
carryforwards for California income tax purposes of approximately
$31.1 million that expire beginning of 2030 if not utilized,
and state research and development tax credit carryforwards of
approximately $3.8 million which can be carried forward

approximately $1.1 million that begin to expire in 2025. The
Company had approximately insignificant and $0.2 million of

In connection with the closing of the Series B financing in August
2011, the Company issued warrants for the purchase of 574,953
shares of Series B convertible preferred stock. The exercise price
of the warrants was $0.09 per share. The preferred stock warrant
liability was measured at fair value on a recurring basis. Changes
in fair value were recorded in change in fair value of preferred
stock warrant liability in the Statements of Operations and
Comprehensive Loss. As of December 31, 2013, the fair value of
this convertible preferred stock warrant liability amounted to
$6.5 million. Just prior to the IPO close date of
June 24, 2014, the preferred stock warrant liability was
remeasured prior to the net exercise of the warrants using the IPO

The Company is focused on enhancing the way patients with
cardiorenal and gastrointestinal, or GI, diseases are treated by
using the gut as the gateway to delivering medicines that matter.
The Company has pioneered the development of small molecule

avoiding potentially negative side effects on the rest of the body.
The Company’s strategy is to evolve from <font style="WHITE-SPACE: nowrap">R&D-focused</font> to an integrated biotech

In May, 2014, the Financial Accounting Standards Board
(“FASB”) issued Accounting Standards Update
(“ASU”) <font style="WHITE-SPACE: nowrap">2014-09,</font> <i>Revenue from Contracts with
Customers</i> (“ASU <font style="WHITE-SPACE: nowrap">2014-09”),</font> which requires an entity to
recognize the amount of revenue to which it expects to be entitled
for the transfer of promised goods or services to customers.
ASU <font style="WHITE-SPACE: nowrap">2014-09</font> will replace most existing
revenue recognition guidance in U.S. GAAP when it becomes
effective. In July 2015, the FASB voted to approve a deferral of
the effective date of this ASU by one year, and to permit entities
to adopt up to one year earlier if they choose. Therefore, the new
standard will become effective for the Company on January 1,
2018 and early application is permitted for periods beginning on or
after January 1, 2017. The standard permits the use of either
the retrospective or cumulative effect transition method. Since the
issuance of ASU <font style="WHITE-SPACE: nowrap">2014-09,</font> the FASB has issued several
amendments which clarify certain points in the new Topic
606 <i>- Revenue
from Contracts with Customers</i>, including ASU <font style="WHITE-SPACE: nowrap">2016-08</font> (“Principal versus Agent
Considerations—Reporting Revenue Gross versus Net”),
ASU <font style="WHITE-SPACE: nowrap">2016-10</font> (“Identifying
Performance Obligations and Licensing”), ASU <font style="WHITE-SPACE: nowrap">2016-11</font> (“Rescission of SEC
Guidance Because of Accounting Standards Updates <font style="WHITE-SPACE: nowrap">2014-09</font> and <font style="WHITE-SPACE: nowrap">2014-16</font> Pursuant to Staff
Announcements at the March 3, 2016 EITF Meeting”) and
ASU <font style="WHITE-SPACE: nowrap">2016-12</font> (“Narrow-Scope
Improvements and Practical Expedients”). The Company plans to
adopt all these standards on January 1, 2018. The Company
plans to modify its accounting policies to reflect the requirements
of these standards and plans to select the modified retrospective
transition method. The Company did not recognize revenue for the
year ended December 31, 2016, and therefore, the planned
adoption of this standard will not affect the Company’s
consolidated financial statements and related disclosures for these
periods or future periods until the Company reports revenues.</p>

intended to define management’s responsibility to evaluate
whether there is substantial doubt about an organization’s
ability to continue as a going concern and to provide related
footnote disclosures, if required. The Company adopted
ASU <font style="WHITE-SPACE: nowrap">2014-15</font> for the year ended
December 31, 2016 and this ASU applies to all future annual
and interim reporting periods. The adoption of ASU <font style="WHITE-SPACE: nowrap">2014-15</font> did not have a material effect
on the Company’s consolidated financial statements and
related disclosures, although it could have an impact on
disclosures in future periods.</p>

In February 2016, the FASB issued ASU <font style="WHITE-SPACE: nowrap">No. 2016-02,</font> <i>Leases (Topic 842)</i>.

lease liability and a <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">right-of-use</font></font> asset for all leases (with the
exception of short term leases) at the commencement date. Lessor
accounting under ASU <font style="WHITE-SPACE: nowrap">2016-02</font> is largely unchanged.
ASU <font style="WHITE-SPACE: nowrap">2016-02</font> is effective for annual and
interim periods beginning on or after December 15, 2018 and
early adoption is permitted. Under ASU <font style="WHITE-SPACE: nowrap">2016-02,</font> lessees (for capital and
operating leases) and lessors (for sales-type, direct financing,
and operating leases) must apply a modified retrospective
transition approach for leases existing at, or entered into after,
the beginning of the earliest comparative period presented in the
financial statements. Lessees and lessors may not apply a full
retrospective transition approach. The Company has not yet selected
an implementation date nor has it determined the effect of the

In March 2016, the FASB issued Accounting Standards <font style="WHITE-SPACE: nowrap">2016-09,</font> <i>Improvements to Employee
Share-Based Payment Accounting</i>, which amends ASC Topic 718,
Stock Compensation. The objective of this amendment is part of the
FASB’s Simplification Initiative as it applies to several
aspects of the accounting for share-based payment transactions,
including the income tax consequences, classification of awards as
either equity or liabilities, and classification on the statement
of cash flows. The Company elected early adoption of
ASU <font style="WHITE-SPACE: nowrap">2016-09</font> in the in the fourth quarter
of 2016 which required us to reflect any adjustments as of
January 1, 2016. Upon adoption, excess tax benefits or
deficiencies from share-based award activity are reflected in the
consolidated statements of operations as a component of the
provision for income taxes, whereas they previously were recognized
in equity. The adoption resulted in approximately $0.8 million
income tax benefit recognized, before full valuation allowance, as
of December 31, 2016. The previously unrecognized excess tax
benefit of approximately $0.7 million<b><i> </i></b>as of January 1,
2016 was recorded as an increase to deferred tax asset with the
corresponding increase to valuation allowance and no impact to the
beginning retained earnings.<b><i> </i></b>The Company did not
change its policy with respect to the treatment of forfeitures;
and, the Company continues estimating the number of forfeitures. As
such, this has no cumulative effect on retained earnings upon
adoption. With the early adoption of <font style="WHITE-SPACE: nowrap">2016-09,</font> the Company has elected to
present the cash flow statement on a prospective transition method
where no prior periods have been adjusted.</p>

(ASU) <font style="WHITE-SPACE: nowrap">2016-15,</font> <i>Statement of Cash Flows
(Topic 230): Classification of Certain Cash Receipts and Cash
Payments</i>, which provides additional guidance on the
presentation and classification of certain items in the statement
of cash flows. The amendments are effective for public business
entities for fiscal years beginning after December 15, 2017,
and interim periods within those fiscal years. Early adoption is
permitted and the standard shall be applied retrospectively. The
adoption of ASU <font style="WHITE-SPACE: nowrap">2016-15</font> is not expected to have a

In November 2016, the FASB issued ASU <font style="WHITE-SPACE: nowrap">2016-18,</font> <i>Restricted

requires amounts generally described as restricted cash and
restricted cash equivalents be included with cash and cash
equivalents when reconciling the total beginning and ending amounts
for the periods shown on the statement of cash flows.
ASU <font style="WHITE-SPACE: nowrap">2016-08</font> is effective for fiscal years
beginning after December 15, 2018 (including interim periods
within those periods) using a retrospective transition method to
each period presented. The adoption of ASU <font style="WHITE-SPACE: nowrap">2016-18</font> is not expected to have a

The Company uses the asset and liability method of accounting for
income taxes. Under this method, deferred tax assets and
liabilities are determined based on the differences between the
financial reporting and the tax bases of assets and liabilities and
are measured using the enacted tax rates and laws that will be in
effect when the differences are expected to reverse. A valuation
allowance is provided when it is more likely than not that some
portion or all of a deferred tax asset will not be realized.</p>

The preparation of consolidated financial statements in conformity
with US GAAP requires management to make estimates and
judgments that affect the amounts reported in the consolidated
financial statements and accompanying notes. On an ongoing basis,
management evaluates its estimates, including those related to
revenue, clinical trial accruals, contract manufacturing accruals,
fair value of assets and liabilities, income taxes, and stock-based
compensation. Management bases its estimates on historical
experience and on various other market-specific and relevant
assumptions that management believes to be reasonable under the
circumstances. Actual results could differ from those
estimates.</p>

The preparation of consolidated financial statements in conformity
with US GAAP requires management to make estimates and
judgments that affect the amounts reported in the consolidated
financial statements and accompanying notes. On an ongoing basis,
management evaluates its estimates, including those related to
revenue, clinical trial accruals, contract manufacturing accruals,
fair value of assets and liabilities, income taxes, and stock-based
compensation. Management bases its estimates on historical
experience and on various other market-specific and relevant
assumptions that management believes to be reasonable under the
circumstances. Actual results could differ from those
estimates.</p>

The Company has never been profitable on an annual basis and, as of
December 31, 2016, the Company has an accumulated deficit of
$213.9 million. The Company has incurred net losses of
approximately $112.4 million, $29.6 million and
$3.2 million in the years ended December 31, 2016, 2015
and 2014, respectively. The Company expects to continue to incur
net operating losses for the foreseeable future, as the Company
continues the development of, seeks regulatory approval for, and if
approved, begins to commercialize, tenapanor and RDX7675. The
Company will need additional funding to support its future
operating activities and adequate funding may not be available to
the Company on acceptable terms, or at all. The Company’s
failure to obtain sufficient funds on acceptable terms when needed
could have a material adverse effect on the business, results of
operations, and financial condition. The Company will need to
generate significant revenues to achieve profitability and may
never do so.</p>

The carrying value of long-lived assets, including property and
equipment, are reviewed for impairment whenever events or changes
in circumstances indicate that the asset may not be recoverable. An
impairment loss is recognized when the total of estimated future
undiscounted cash flows, expected to result from the use of the
asset and its eventual disposition, are less than its carrying
amount. Impairment, if any, would be assessed using discounted cash
flows or other appropriate measures of fair value. Through
December 31, 2016, there have been no such impairment
losses.</p>

The Company uses the asset and liability method of accounting for
income taxes. Under this method, deferred tax assets and
liabilities are determined based on the differences between the
financial reporting and the tax bases of assets and liabilities and
are measured using the enacted tax rates and laws that will be in
effect when the differences are expected to reverse. A valuation
allowance is provided when it is more likely than not that some
portion or all of a deferred tax asset will not be realized.</p>

Revenue from research activities made under collaboration
partnership agreements are recognized as the services are provided
and when there is persuasive evidence that an arrangement exists,
delivery has occurred, the price is fixed or determinable, and
collectability is reasonably assured. Revenue generated from
research and licensing agreements typically includes <font style="WHITE-SPACE: nowrap">up-front</font> signing or license fees, cost
reimbursements, research services, minimum sublicense fees,
milestone payments, and royalties on future licensees’
product sales.</p>

For revenue agreements with multiple-element arrangements, such as
license and development agreements, the Company allocates revenue
to each unit of accounting based on the relative selling price of
each unit. When applying the relative selling price method, the
Company determines the selling price for each deliverable using
vendor-specific objective evidence or third-party evidence. If
neither exists, the Company uses its best estimate of selling price
for that deliverable. Revenue allocated is then recognized when the
four basic revenue recognition criteria are met for each
deliverable.</p>

The Company recognizes revenue from upfront payments ratably over
the term of its estimated period of performance under the agreement
which is recorded as licensing revenue. Reimbursements for
development costs incurred under the Company’s license
agreement with AstraZeneca are classified as collaborative
development revenue. The Company recognizes cost reimbursement
revenue under collaboration partnership agreements as the related
research and development costs for services are rendered. Deferred
revenue represents the portion of research or license payments
received which has not been earned.</p>

As part of the process of preparing our financial statements, the
Company is required to estimate its accrued expenses. This process
involves reviewing open contracts and purchase orders,
communicating with its personnel to identify services that have
been performed on its behalf and estimating the level of service
performed and the associated cost incurred for the service when the
Company has not yet been invoiced or otherwise notified of the
actual cost. The majority of the Company’s service providers
invoice its monthly invoices in arrears for services performed or
when contractual milestones are met. The Company makes estimates of
its accrued expenses as of each balance sheet date in its financial
statements based on facts and circumstances known to the Company at
that time. The Company periodically confirms the accuracy of its
estimates with the service providers and make adjustments if
necessary. Examples of estimated accrued research and development
expenses include fees paid to:</p>

The Company records expenses related to clinical studies and
manufacturing development activities based on its estimates of the
services received and efforts expended pursuant to contracts with
multiple CROs and manufacturing vendors that conduct and manage
these activities on its behalf. The financial terms of these
agreements are subject to negotiation, vary from contract to
contract, and may result in uneven payment flows. There may be
instances in which payments made to the Company’s vendors
will exceed the level of services provided and result in a
prepayment of the expense. Payments under some of these contracts
depend on factors such as the successful enrollment of subjects and
the completion of clinical trial milestones. In accruing service
fees, the Company estimates the time period over which services
will be performed, enrollment of subjects, number of sites
activated and the 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 the Company’s estimate, the Company will
adjust the accrued or prepaid expense balance accordingly. To date,
there have been no material differences from the Company’s
estimates to the amounts actually incurred.</p>

The Company recognizes compensation expense for all share-based
payment awards made to employees and directors based on estimated
fair values. For employee stock options, the Company determines the
grant date fair value of the awards using the Black-Scholes
option-pricing model and generally recognizes the fair value as
stock-based compensation expense on a straight-line basis over the
vesting period of the respective awards. Stock-based compensation
expense is based on the value of the portion of stock-based payment
awards that is ultimately expected to vest. As such, the
Company’s stock-based compensation is reduced for the
estimated forfeitures at the date of grant and revised, if
necessary, in subsequent periods if actual forfeitures differ from
those estimates. For restricted stock, the compensation cost for
these awards is based on the closing price of the Company’s
common stock on the date of grant and recognized as compensation
expense on a straight-line basis over the requisite service
period.</p>

The Company accounts for equity instruments issued to nonemployees
based on their fair values on the measurement dates using the
Black-Scholes option-pricing model. The estimated fair values of
the options granted to nonemployees are remeasured as they vest. As
a result, the noncash charge to operations for nonemployee options
with vesting conditions is affected each reporting period by
changes in the fair value of the Company’s common stock.</p>

In May, 2014, the Financial Accounting Standards Board
(“FASB”) issued Accounting Standards Update
(“ASU”) <font style="WHITE-SPACE: nowrap">2014-09,</font> <i>Revenue from Contracts with
Customers</i> (“ASU <font style="WHITE-SPACE: nowrap">2014-09”),</font> which requires an entity to
recognize the amount of revenue to which it expects to be entitled
for the transfer of promised goods or services to customers.
ASU <font style="WHITE-SPACE: nowrap">2014-09</font> will replace most existing
revenue recognition guidance in U.S. GAAP when it becomes
effective. In July 2015, the FASB voted to approve a deferral of
the effective date of this ASU by one year, and to permit entities
to adopt up to one year earlier if they choose. Therefore, the new
standard will become effective for the Company on January 1,
2018 and early application is permitted for periods beginning on or
after January 1, 2017. The standard permits the use of either
the retrospective or cumulative effect transition method. Since the
issuance of ASU <font style="WHITE-SPACE: nowrap">2014-09,</font> the FASB has issued several
amendments which clarify certain points in the new Topic
606 <i>- Revenue

adopt all these standards on January 1, 2018. The Company
plans to modify its accounting policies to reflect the requirements
of these standards and plans to select the modified retrospective

year ended December 31, 2016, and therefore, the planned

lease liability and a <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">right-of-use</font></font> asset for all leases (with the
exception of short term leases) at the commencement date. Lessor
accounting under ASU <font style="WHITE-SPACE: nowrap">2016-02</font> is largely unchanged.
ASU <font style="WHITE-SPACE: nowrap">2016-02</font>is effective for annual and
interim periods beginning on or after December 15, 2018
and  early adoption
is permitted. Under ASU <font style="WHITE-SPACE: nowrap">2016-02,</font> lessees (for capital and
operating leases) and lessors (for sales-type, direct financing,
and operating leases) must apply a modified retrospective
transition approach for leases existing at, or entered into after,
the beginning of the earliest comparative period presented in the
financial statements. Lessees and lessors may not apply a full
retrospective transition approach. The Company has not yet selected
an implementation date nor has it determined the effect of the
standard on the Company’s ongoing financial reporting.</p>

In March 2016, the FASB issued Accounting Standards <font style="WHITE-SPACE: nowrap">2016-09,</font> <i>Improvements to Employee
Share-Based Payment Accounting</i>, which amends ASC Topic 718,
Stock Compensation. The objective of this amendment is part of the
FASB’s Simplification Initiative as it applies to several
aspects of the accounting for share-based payment transactions,
including the income tax consequences, classification of awards as
either equity or liabilities, and classification on the statement
of cash flows. The Company elected early adoption of
ASU <font style="WHITE-SPACE: nowrap">2016-09</font> in the in the fourth quarter
of 2016 which required us to reflect any adjustments as of
January 1, 2016. Upon adoption, excess tax benefits or
deficiencies from share-based award activity are reflected in the
consolidated statements of operations as a component of the
provision for income taxes, whereas they previously were recognized
in equity. The adoption resulted in approximately $0.8 million
income tax benefit recognized, before full valuation allowance, as
of December 31, 2016. The previously unrecognized excess tax
benefit of approximately $0.7 million<b><i> </i></b>as of January 1,
2016 was recorded as an increase to deferred tax asset with the
corresponding increase to valuation allowance and no impact to the
beginning retained earnings.<b><i> </i></b>The Company did not
change its policy with respect to the treatment of forfeitures;
and, the Company continues estimating the number of forfeitures. As
such, this has no cumulative effect on retained earnings upon
adoption. With the early adoption of <font style="WHITE-SPACE: nowrap">2016-09,</font> the Company has elected to
present the cash flow statement on a prospective transition method
where no prior periods have been adjusted.</p>

(ASU) <font style="WHITE-SPACE: nowrap">2016-15,</font> <i>Statement of Cash Flows
(Topic 230): Classification of Certain Cash Receipts and Cash
Payments</i>, which provides additional guidance on the
presentation and classification of certain items in the statement
of cash flows. The amendments are effective for public business
entities for fiscal years beginning after December 15, 2017,
and interim periods within those fiscal years. Early adoption is
permitted and the standard shall be applied retrospectively. The
adoption of ASU <font style="WHITE-SPACE: nowrap">2016-15</font> is not expected to have a

In November 2016, the FASB issued ASU <font style="WHITE-SPACE: nowrap">2016-18,</font> <i>Restricted

requires amounts generally described as restricted cash and
restricted cash equivalents be included with cash and cash
equivalents when reconciling the total beginning and ending amounts
for the periods shown on the statement of cash flows.
ASU <font style="WHITE-SPACE: nowrap">2016-08</font> is effective for fiscal years
beginning after December 15, 2018 (including interim periods
within those periods) using a retrospective transition method to

Revenue from research activities made under collaboration
partnership agreements are recognized as the services are provided
and when there is persuasive evidence that an arrangement exists,
delivery has occurred, the price is fixed or determinable, and
collectability is reasonably assured. Revenue generated from
research and licensing agreements typically includes <font style="WHITE-SPACE: nowrap">up-front</font> signing or license fees, cost
reimbursements, research services, minimum sublicense fees,
milestone payments, and royalties on future licensees’
product sales.</p>

For revenue agreements with multiple-element arrangements, such as
license and development agreements, the Company allocates revenue
to each unit of accounting based on the relative selling price of
each unit. When applying the relative selling price method, the
Company determines the selling price for each deliverable using
vendor-specific objective evidence or third-party evidence. If
neither exists, the Company uses its best estimate of selling price
for that deliverable. Revenue allocated is then recognized when the
four basic revenue recognition criteria are met for each
deliverable.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: "Times New Roman"; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px">
The Company recognizes revenue from upfront payments ratably over
the term of its estimated period of performance under the agreement
which is recorded as licensing revenue. Reimbursements for
development costs incurred under the Company’s license
agreement with AstraZeneca are classified as collaborative
development revenue. The Company recognizes cost reimbursement
revenue under collaboration partnership agreements as the related
research and development costs for services are rendered. Deferred
revenue represents the portion of research or license payments
received which has not been earned.</p>

Revenues from milestones, if they are nonrefundable and deemed
substantive, are recognized upon successful accomplishment of the
milestones. To the extent that <font style="WHITE-SPACE: nowrap">non-substantive</font> milestones are achieved and
the Company has remaining performance obligations, milestones are
deferred and recognized as revenue over the estimated remaining
period of performance. The Company will recognize revenue
associated with the <font style="WHITE-SPACE: nowrap">non-substantive</font> milestones upon achievement of
the milestone if there are no undelivered units and it has no
remaining performance obligations. The Company will account for
sales-based milestones as royalties that will be recognized as
revenue upon achievement of the milestone.</p>

The Company has never been profitable on an annual basis and, as of
December 31, 2016, the Company has an accumulated deficit of
$213.9 million. The Company has incurred net losses of
approximately $112.4 million, $29.6 million and
$3.2 million in the years ended December 31, 2016, 2015
and 2014, respectively. The Company expects to continue to incur
net operating losses for the foreseeable future, as the Company
continues the development of, seeks regulatory approval for, and if
approved, begins to commercialize, tenapanor and RDX7675. The
Company will need additional funding to support its future
operating activities and adequate funding may not be available to
the Company on acceptable terms, or at all. The Company’s
failure to obtain sufficient funds on acceptable terms when needed
could have a material adverse effect on the business, results of
operations, and financial condition. The Company will need to
generate significant revenues to achieve profitability and may
never do so.</p>

As part of the process of preparing our financial statements, the
Company is required to estimate its accrued expenses. This process
involves reviewing open contracts and purchase orders,
communicating with its personnel to identify services that have
been performed on its behalf and estimating the level of service
performed and the associated cost incurred for the service when the
Company has not yet been invoiced or otherwise notified of the
actual cost. The majority of the Company’s service providers
invoice its monthly invoices in arrears for services performed or
when contractual milestones are met. The Company makes estimates of
its accrued expenses as of each balance sheet date in its financial
statements based on facts and circumstances known to the Company at
that time. The Company periodically confirms the accuracy of its
estimates with the service providers and make adjustments if
necessary. Examples of estimated accrued research and development
expenses include fees paid to:</p>

The Company records expenses related to clinical studies and
manufacturing development activities based on its estimates of the
services received and efforts expended pursuant to contracts with
multiple CROs and manufacturing vendors that conduct and manage
these activities on its behalf. The financial terms of these
agreements are subject to negotiation, vary from contract to
contract, and may result in uneven payment flows. There may be
instances in which payments made to the Company’s vendors
will exceed the level of services provided and result in a
prepayment of the expense. Payments under some of these contracts
depend on factors such as the successful enrollment of subjects and
the completion of clinical trial milestones. In accruing service
fees, the Company estimates the time period over which services
will be performed, enrollment of subjects, number of sites
activated and the 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 the Company’s estimate, the Company will
adjust the accrued or prepaid expense balance accordingly. To date,
there have been no material differences from the Company’s
estimates to the amounts actually incurred.</p>
