<p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px; TEXT-INDENT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">Patent costs
consist primarily of external legal costs, filing fees incurred to
file patent applications and renewal fees on proprietary technology
developed or licensed by the Company. Patent costs associated with
applying for a patent, being issued a patent and annual renewal
fees are capitalized. Costs to defend a patent and costs to
invalidate a competitor’s patent or patent application are
expensed as incurred. Patent costs are amortized on a straight-line
basis over the shorter of the estimated economic lives or the
initial term of the patents, generally 20 years. Patent
amortization expense was $0.4 million, $0.6 million and $0.5
million for the years ended December 31, 2013, 2012 and 2011,
respectively. The Company also expensed the remaining net book
value of previously capitalized patents that were later abandoned
of $0.5 million, $0.4 million and $0.2 million in 2013, 2012 and
2011, respectively. The Company expects to incur amortization
expense of approximately $0.5 million per year over the next five
years based on the unamortized patent costs as of December 31,
2013.</font></p>

government are cost plus contracts providing for reimbursed costs
which include overhead and general and administrative costs and a

non-refundable upfront license fees, data transfer fees, research
reimbursement payments, exclusive licensed rights to patented or
patent pending compounds, technology access fees, various
performance or sales milestones and future product royalty
payments. Some of these arrangements are multiple element
arrangements. The Company defers recognition of non-refundable
upfront fees if it has continuing performance obligations without
which the technology, right, product or service conveyed in
conjunction with the non-refundable fee has no utility to the
licensee that is separate and independent of Company performance
under the other elements of the arrangement. In addition, if the
Company has continuing involvement through research and development
services that are required because of its know-how and expertise
related to the technology that is proprietary to the Company, or
can only be performed by the Company, then such up-front fees are

<font style="FONT-FAMILY: Times New Roman" size="2"><b><i>Charley’s Fund Agreement</i></b></font></p>
<p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px; TEXT-INDENT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">In October
2007, Charley’s Fund, Inc. (“Charley’s
Fund”), a nonprofit organization that funds drug development
and discovery initiatives specific to DMD, awarded the Company a
$2.45 million research grant and, in May 2009, the grant
authorization was increased to a total of $5.0 million. Pursuant to
the related sponsored research agreement, the grant was provided to
support the development of product candidates which utilize the
Company’s proprietary technologies. The grant requires the
Company to make mid single-digit percentage royalty payments on net
sales of any such products that are successfully commercialized up
to the total amount received under the grant.</font></p>
<p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px; TEXT-INDENT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">As of
December 31, 2013, Charley’s Fund has made payments of
approximately $3.4 million to the Company. Revenue associated
with this research and development arrangement is recognized based
on the proportional performance method, using the payment received
method. To date, the Company has recognized $0.1 million as
revenue, but did not recognize any revenue for the years ended
December 31, 2013, 2012 and 2011. The Company does not expect
to receive any incremental funding under the grant and has deferred
$3.3 million of previous receipts which is anticipated to be
recognized as revenue once the Company completes the remaining
milestones and they are agreed to by Charley’s
Fund.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2"><b><i>Isis—Ercole Agreement</i></b></font></p>
<p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 6px; TEXT-INDENT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">In May 2003,
Ercole Biotechnology, Inc., or Ercole, and Isis Pharmaceuticals,
Inc. or Isis, entered into a collaboration and license agreement
related to RNA splicing. Research collaboration activity defined in
the agreement expired in 2006. In March 2008, the Company acquired
all of the stock of Ercole in exchange for 5,811,721 shares of the
Company’s common stock, which was valued at approximately
$8.4 million, and the assumption of approximately $1.8 million in
liabilities of Ercole. The Company also issued warrants to purchase
its common stock (also classified as equity), which were valued at
$0.4 million, in exchange for certain outstanding warrants issued
by Ercole. In connection with the March 2008 acquisition, the
Company assumed Ercole’s obligations under the Isis
agreement. This agreement contains several cross-licenses between
the parties granting each party certain exclusive and nonexclusive
rights under a selected set of the other parties’ patents and
patent applications for the research, development, and
commercialization of antisense therapeutics using RNA splicing with
respect to certain gene targets.</font></p>
<p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px; TEXT-INDENT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">Subject to the
satisfaction of certain milestones triggering the obligation to
make any such payments, the Company may be obligated to make
milestone payments to Isis of up to $23.4 million in the
aggregate for each product developed under a licensed patent under
this agreement.</font></p>
<p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px; TEXT-INDENT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">As of
December 31, 2013, the Company has not made, and is not under
any current obligation to make, any such milestone payments, as the
conditions triggering any such milestone payment obligations have
not been satisfied. The range of percentage royalty payments
required to be made by the Company under the terms of this
agreement is from a fraction of a percent to mid single-digit
percentages. The Company believes that its DMD, Ebola, Marburg and
influenza programs will not fall under the scope of this agreement
and therefore will not be subject to milestone or royalty
obligations under its provisions.</font></p>
<p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px; TEXT-INDENT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">Subject to the
satisfaction of certain milestones triggering the obligation to
make any such payments, Isis may be obligated to make milestone
payments to the Company of up to $21.1 million in the
aggregate for each product developed under a licensed patent under
this agreement. As of December 31, 2013, Isis has not made,
and is not under any current obligation to make, any such milestone
payments, as the conditions triggering any such milestone payment
obligations have not been satisfied. The percentage royalty
payments required to be made by Isis under the terms of this
agreement is a fraction of a percent. As to any product
commercialized under the agreement, the agreement will terminate on
the expiration date of the last to expire licensed patent covering
such product. The last to expire Sarepta owned patent covered under
this agreement expires on September 9, 2014. The last Isis
owned patent covered under this agreement expires on March 27,
2028. In addition, either party may terminate this agreement in the
event:</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">The risk-free
interest rate is estimated using an average of U.S. Treasury bill
interest rates that correlate to the prevailing interest rates at
the time of the valuation date. The expected dividend yield is zero
as the Company has not paid any dividends to date and does not
expect to pay dividends prior to the expiration of the warrants.
The expected lives are based on the remaining contractual lives of
the related warrants at the valuation date. For the year ended
December 31, 2013, expected volatility was estimated using a
blend of calculated volatility of the Company’s common stock
over a historical period and implied volatility in exchange-traded
options associated with the Company’s common stock. Prior to
January 1, 2013, expected volatility was estimated using
calculated volatility of the Company’s common stock over a
historical period commensurate with the expected term of the
option. The amounts estimated according to the Black-Scholes-Merton
option-pricing model may not be indicative of the actual values
realized upon the exercise of these warrants by the
holders.</font></p>

follows the asset and liability method of accounting for income
taxes. Deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the
consolidated financial statement carrying amounts of existing
assets and liabilities and their respective tax bases and operating
loss and tax credit carryforwards. It is the intention of the
Company to reinvest the earnings of its non-U.S. subsidiaries in
those operations and not to repatriate the earnings to the United
States. Accordingly, the Company does not provide for deferred
taxes on the excess of the financial reporting over the tax basis
in its investments in foreign subsidiaries as they are considered
permanent in duration. To date, the Company has not had any
earnings in its non-U.S. subsidiaries.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">Deferred tax
assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered and settled. A
valuation allowance is recorded to reduce the net deferred tax
asset to zero because it is more likely than not that the net
deferred tax asset will not be realized. The Company recognizes the
effect of income tax positions only if those positions are more
likely than not of being sustained upon an examination.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">In 2009, the
Company listed for sale the industrial property it owns in
Corvallis, Oregon. In connection with this decision, the Company
classified the property as “Property held for sale” and
ceased depreciating the property. While the property was held for
sale, the Company, with the assistance of independent appraisals,
periodically estimated the fair market value less the costs to sell
the property and in 2011 and 2010, recorded impairment charges of
$0.1 million and $0.4 million, respectively. In November 2011, the
Company leased approximately 70% of the building to a third party
through March 31, 2017 at rates ranging from $14,500 per month
to $15,500 per month. Under the terms of the agreement, the third
party can terminate the lease in November 2014 upon proper notice
and delivery of a termination fee. In addition, the third party has
the option to purchase the building for prices ranging from
$2.0 million to $2.2 million during the initial lease
term. Upon entering into the lease agreement, the Company
reclassified the $1.9 million carrying value of the building from
“Property held for sale” to “Property and
equipment” and began depreciating the building over 30 years
which is the remaining term of the ground lease. Rent earned on the
building is recorded as “Interest income and other,
net” and was $0.2 million and $0.1 million in 2013 and 2012,
respectively.</font></p>

per share is computed by dividing net loss by the weighted-average

per share is computed by dividing net income (if any) by the
weighted-average number of common shares and dilutive common stock
equivalent shares outstanding. Given that the Company was in a loss
position for each of the periods presented, there is no difference
between basic and diluted net loss per share since the effect of
common stock equivalents would be anti-dilutive and are therefore

All inter-company transactions between and among its consolidated
subsidiaries have been eliminated. The consolidated financial
statements have been prepared in accordance with accounting
principles generally accepted in the United States of America
(“GAAP”). Management has determined that the Company
operates in one segment: the development of pharmaceutical products
on its own behalf or in collaboration with others.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">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
revenue and expenses during the reporting period. Actual results
could differ from those estimates. Significant items subject to
such estimates and assumptions include the valuation of stock-based
awards and liability classified warrants, research and development
expenses, and revenue recognition.</font></p>

$0.1 million and $0.4 million, respectively. In November 2011, the
Company leased approximately 70% of the building to a third party
through March 31, 2017 at rates ranging from $14,500 per month
to $15,500 per month. Under the terms of the agreement, the third
party can terminate the lease in November 2014 upon proper notice
and delivery of a termination fee. In addition, the third party has
the option to purchase the building for prices ranging from
$2.0 million to $2.2 million during the initial lease
term. Upon entering into the lease agreement, the Company
reclassified the $1.9 million carrying value of the building from
“Property held for sale” to “Property and
equipment” and began depreciating the building over 30 years
which is the remaining term of the ground lease. Rent earned on the
building is recorded as “Interest income and other,
net” and was $0.2 million and $0.1 million in 2013 and 2012,
respectively.</font></p>

consist primarily of external legal costs, filing fees incurred to
file patent applications and renewal fees on proprietary technology
developed or licensed by the Company. Patent costs associated with
applying for a patent, being issued a patent and annual renewal
fees are capitalized. Costs to defend a patent and costs to
invalidate a competitor’s patent or patent application are
expensed as incurred. Patent costs are amortized on a straight-line
basis over the shorter of the estimated economic lives or the
initial term of the patents, generally 20 years. Patent
amortization expense was $0.4 million, $0.6 million and $0.5
million for the years ended December 31, 2013, 2012 and 2011,
respectively. The Company also expensed the remaining net book
value of previously capitalized patents that were later abandoned
of $0.5 million, $0.4 million and $0.2 million in 2013, 2012 and
2011, respectively. The Company expects to incur amortization
expense of approximately $0.5 million per year over the next five
years based on the unamortized patent costs as of December 31,
2013.</font></p>

contracts and grants. See “Note 6—Government
Contracts.” The Company’s contracts with the U.S.
government are cost plus contracts providing for reimbursed costs
which include overhead and general and administrative costs and a
target fee. The Company recognizes revenue from U.S. government
research contracts during the period in which the related expenses
are incurred and presents such revenues and related expenses gross

reimbursement payments, exclusive licensed rights to patented or
patent pending compounds, technology access fees, various
performance or sales milestones and future product royalty
payments. Some of these arrangements are multiple element
arrangements. The Company defers recognition of non-refundable
upfront fees if it has continuing performance obligations without
which the technology, right, product or service conveyed in
conjunction with the non-refundable fee has no utility to the
licensee that is separate and independent of Company performance
under the other elements of the arrangement. In addition, if the
Company has continuing involvement through research and development
services that are required because of its know-how and expertise
related to the technology that is proprietary to the Company, or
can only be performed by the Company, then such up-front fees are
deferred and recognized over the period of continuing
involvement.</font></p>

follows the asset and liability method of accounting for income
taxes. Deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the
consolidated financial statement carrying amounts of existing
assets and liabilities and their respective tax bases and operating
loss and tax credit carryforwards. It is the intention of the
Company to reinvest the earnings of its non-U.S. subsidiaries in
those operations and not to repatriate the earnings to the United
States. Accordingly, the Company does not provide for deferred
taxes on the excess of the financial reporting over the tax basis
in its investments in foreign subsidiaries as they are considered
permanent in duration. To date, the Company has not had any
earnings in its non-U.S. subsidiaries.</font></p>

assets and liabilities are measured using enacted tax rates

valuation allowance is recorded to reduce the net deferred tax
asset to zero because it is more likely than not that the net
deferred tax asset will not be realized. The Company recognizes the
effect of income tax positions only if those positions are more
likely than not of being sustained upon an examination.</font></p>

assets held and used by the Company and intangible assets with

be held and used by comparing the carrying amount of an asset to
future net undiscounted cash flows to be generated by the asset. If
such assets are considered to be impaired, the impairment to be
recognized is measured as the amount by which the carrying amount
of the assets exceeds the fair value of the assets. Such reviews
assess the fair value of the assets based upon estimates of future
cash flows that the assets are expected to generate.</font></p>

the NOL or tax credit carryforward would be available to reduce the
additional taxable income or tax due if the tax position is
disallowed. The new guidance is effective for annual and interim
periods for fiscal years beginning after December 15, 2013,
and early adoption is permitted. Since the guidance relates only to
the presentation of unrecognized tax benefits, the Company does not
expect its adoption in January 2014 will have a material effect on

assets held and used by the Company and intangible assets with

be held and used by comparing the carrying amount of an asset to
future net undiscounted cash flows to be generated by the asset. If
such assets are considered to be impaired, the impairment to be
recognized is measured as the amount by which the carrying amount
of the assets exceeds the fair value of the assets. Such reviews

Therapeutics, Inc. and its wholly-owned subsidiaries
(“Sarepta” or the “Company”) is a
biopharmaceutical company focused on the discovery and development
of unique RNA-based therapeutics for the treatment of rare and
infectious diseases. Applying the Company’s proprietary
platform technologies, the Company is able to target a broad range
of diseases and disorders through distinct RNA-based mechanisms of
action. The Company is focused on advancing the development of its
Duchenne muscular dystrophy (DMD) drug candidates, including its
lead product candidate, eteplirsen, for which the Company is
currently conducting an ongoing open label extension study
following completion of its initial Phase IIb clinical trials. The
Company is also focused on developing therapeutics for the
treatment of infectious diseases, including its lead infectious
disease program aimed at the development of a drug candidate for
the Marburg hemorrhagic fever virus for which the Company has
historically received significant financial support from U.S.
government research contracts.</font></p>
<p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px; TEXT-INDENT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">Since its
inception in 1980, the Company has incurred losses of approximately
$543.2 million, substantially all of which resulted from
expenditures related to research and development and general and
administrative charges partially offset by revenue generated from
research contracts with and grants from the U.S. government. As of
December 31, 2013, the Company has completed all of its
contracts with the U.S. government except for the July 2010
agreement and the August 2012 agreement for the development of
therapeutics against the Marburg virus. The Company has not
generated any material revenue from product sales to date, and
there can be no assurance that revenues from product sales will be
achieved. Moreover, even if the Company does achieve revenue from
product sales, the Company is likely to continue to incur operating
losses in the near term.</font></p>
<p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px; TEXT-INDENT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">As of
December 31, 2013, the Company had $264.9 million of cash,
cash equivalents and invested cash, comprised of $257.0 million of
cash and cash equivalents and $7.9 million of restricted
investments, which the Company believes, taking into consideration
outstanding warrants, is sufficient to fund its current operational
plan for the next twelve months. Should the Company’s funding
from the U.S. government cease or be delayed, the Company would
likely curtail certain of its infectious disease research and
development efforts unless additional funding was obtained. The
Company is also likely to pursue additional cash resources through
public or private financings, seeking additional government
contracts, and from establishing collaborations or licensing its
technology to other companies.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">As of
December 31, 2013, the Company had federal and state net
operating loss carryforwards of $260.9 million and $237.7 million,
respectively, available to reduce future taxable income, which
expire 2014 through 2033. Utilization of these net operating losses
could be limited under Section 382 of the Internal Revenue
Code and similar state laws based on ownership changes and the
value of the Company’s stock. Approximately
$11.6 million of the Company’s carryforwards were
generated as a result of deductions related to exercises of stock
options. When utilized, this portion of the Company’s
carryforwards, as tax affected, will be accounted for as a direct
increase to contributed capital rather than as a reduction of the
year’s provision for income taxes. The principal differences
between net operating loss carryforwards for tax purposes and the
deficit accumulated during the development stage result from timing
differences related to depreciation, amortization, treatment of
research and development costs, limitations on the length of time
that net operating losses may be carried forward, losses on changes
in warrant valuation and differences in the recognition of
stock-based compensation.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">The Company had
gross deferred tax assets of $133.6 million and $114.1 million at
December 31, 2013 and 2012, respectively, primarily from U.S.
federal and state net operating loss carryforwards, U.S. federal
and state research and development credit carryforwards, share
based compensation expense and intangibles. A valuation allowance
was recorded to reduce the net deferred tax asset to zero because
it is more likely than not that the deferred tax asset will not be
realized.</font></p>

the Company granted 32,377 shares of restricted stock units (RSUs)
to employees in lieu of cash for a portion of the 2011 bonus. These
shares vest over a two-year period and have a weighted average
grant date fair value of $5.40 per share. In addition, in August
2012, 7,500 RSUs with a grant date fair value of $10.08 per share

<font style="FONT-FAMILY: Times New Roman" size="2">In February
2013, the Financial Accounting Standards Board (the
“FASB”) issued new guidance which requires disclosure
of significant amounts reclassified out of accumulated other
comprehensive income by component and their corresponding effect on
the respective line items of net income. This guidance was adopted
by the Company in fiscal year 2013. The adoption of this guidance
did not have an impact on the Company’s consolidated
financial statements.</font></p>
<p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px; TEXT-INDENT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">In July 2013,
the FASB issued new guidance which amends the guidance related to
the presentation of unrecognized tax benefits and allows for the
reduction of a deferred tax asset for a NOL carryforward whenever
the NOL or tax credit carryforward would be available to reduce the
additional taxable income or tax due if the tax position is
disallowed. The new guidance is effective for annual and interim
periods for fiscal years beginning after December 15, 2013,
and early adoption is permitted. Since the guidance relates only to
the presentation of unrecognized tax benefits, the Company does not
expect its adoption in January 2014 will have a material effect on
its financial position, results of operations or cash
flows.</font></p>

license agreements for which it is obligated to pay minimum
royalties if the Company does not terminate the relevant agreement.
The notice period to terminate these agreements is six months or
less. Royalty payments under these agreements were $0.1 million for
each of the years ended December 31, 2013, 2012 and
2011.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">The Company is
also obligated to pay royalties upon the net sales of DMD products.
The royalty rates are in the low single-digit percentages for both
inside and outside the United States. In addition, the Company is
obligated to pay Charley’s Fund a mid single-digit percentage
royalty on the net sales of any product developed pursuant to the
agreement with Charley’s Fund up to a maximum of $3.4
million. As of December 31, 2013, the Company has not made any
payments under its Isis—Ercole agreement, and is not under
any current obligation to make any such milestone payments, as the
conditions triggering any such milestone payment obligations have
not been satisfied. The range of percentage royalty payments
required to be made by the Company under the terms of the
Isis—Ercole agreement, should such payments ever be made, is
from a fraction of a percent to mid single-digit percentages (see

Western Australia (UWA) entered into an agreement under which an
existing exclusive license agreement between the Company and UWA
was amended and restated. Under the terms of this agreement, UWA
granted the Company an exclusive license to certain UWA
intellectual property rights in exchange for up to $7.1 million in
upfront and development milestone payments. In 2013, the Company

December 31, 2013, the Company was not a party to any material
legal proceedings with respect to itself, its subsidiaries, or any
of its material properties. In the normal course of business, the
Company may from time to time be named as a party to various legal
claims, actions and complaints, including matters involving
securities, employment, intellectual property, effects from the use
of therapeutics utilizing its technology, or others. For example,
in January 2014, a former consultant of the Company filed a
complaint alleging breach of contract, among other claims, and
seeking approximately $4 million in damages, plus certain
additional fees and costs, from the Company. In addition, purported
class action complaints were filed against the Company and certain
of its officers in the U.S. District Court for the District of
Massachusetts on January 27, 2014 (Corban v. Sarepta et al)
and January 29, 2014 (Baradanian v. Sarepta et al). The
plaintiffs are alleged purchasers of Company common stock who seek
to bring claims on behalf of themselves and persons or entities
that purchased or acquired securities of the Company between
July 24, 2013 and November 12, 2013. The complaints
allege that the defendants violated the federal securities laws in
connection with disclosures related to eteplirsen, the
Company’s lead therapeutic candidate for DMD, and seek
damages in an unspecified amount. Given the relatively early stages
of the proceedings in the above mentioned purported claims, at this
time, no assessment can be made as to the likely outcome of these
claims or whether the outcomes would have a material impact on the
Company.</font></p>
