The Company’s liabilities with fair value categorized as
Level 3 within the fair value hierarchy consist of warrants issued
in January and August 2009. The fair value of these
liabilities is determined using the Black-Scholes-Merton
option-pricing model, which requires the use of significant
judgment and estimates for the inputs in the model. For additional
information related to the determination of fair value of warrants
and a reconciliation of changes in fair value, please read <i>Note

receivable and accounts payable approximate fair value because of
the immediate or short-term maturity of these financial

approximate fair value based on market activity for other debt
instruments with similar characteristics and comparable risk.</p>

<b>6. WARRANTS</b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
The Company has periodically issued warrants in connection with
certain common stock offerings. The warrants issued in
January and August 2009 are classified as liabilities as
opposed to equity due to their settlement terms which require
settlement in registered shares. These warrants are non-cash
liabilities and the Company is not required to expend any cash to
settle these liabilities.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
The outstanding warrants classified as liabilities are recorded on
the unaudited condensed consolidated balance sheets and are
adjusted to fair value at each financial reporting period, with
changes in the fair value being recorded as “Loss on change
in warrant valuation” in the unaudited condensed consolidated
statements of operations and comprehensive loss. Fair value is
determined using the Black-Scholes-Merton option-pricing model,
which requires the use of significant judgment and estimates for
the inputs used in the model.</p>

The Company’s accounts receivable primarily arise from
government research contracts and other grants. They are generally
stated at invoiced amount and do not bear interest. Because the
accounts receivable are primarily from government agencies and
historically no amounts have been written off, an allowance for
doubtful accounts receivable is not considered necessary. As of
June 30, 2014 and December 31, 2013, the accounts
receivable balance included unbilled receivables of $3.9 million
and $2.4 million, respectively. Approximately $2.5 million of the
unbilled receivables as of June 30, 2014 are subject to
government audit and will not be collected until the completion of
the audit.</p>

<b><i>July 2010 Contract (Ebola and Marburg Intravenous
administration)</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
In July 2010, the Company was awarded the Department of Defense
(“DoD”) contract managed by its Joint Project Manager
Medical Countermeasure Systems (“JPM-MCS”) program for
the advanced development of its hemorrhagic fever virus therapeutic
candidates, AVI-6002 and AVI-6003, against Ebola and Marburg
viruses, respectively. In February 2012, the Company announced that
it received permission from the U.S. Food and Drug Administration
(“FDA”) to proceed with a single oligomer from
AVI-7288, one of the two components that make up AVI-6003, as the
lead product candidate against Marburg virus infection. In August
2012, the Company received a stop-work order related to the Ebola
virus portion of the contract and, in October 2012, the DoD
terminated the Ebola portion of the contract for the convenience of
the government due to government funding constraints.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
The Marburg portion of the contract is structured into four
segments and has an aggregate remaining period of performance
spanning approximately four years if the DoD exercises its options
for all segments. Activities under the first segment began in July
2010 and included preclinical studies and Phase I studies in
healthy volunteers. In February 2014, the Company announced
positive safety results from the Phase I multiple ascending dose
study of AVI-7288. However, in July 2014, the contract expired.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
For the three months ended June 30, 2014 and 2013, the Company
recognized $1.7 million and $2.1 million, respectively, as revenue
under this agreement. For the six months ended June 30, 2014
and 2013, the Company recognized $5.8 million and $4.7 million,
respectively, as revenue under this agreement. Due to the
expiration of the contract, only revenue for contract finalization,
if any, is expected in the future.</p>

In August 2012, the Company was awarded a contract from the JPM-MCS
program. The contract was for approximately $3.9 million to
evaluate the feasibility of an intramuscular route of
administration using AVI-7288, the Company’s candidate for
treatment of Marburg virus. The period of performance for this
contract concluded in the third quarter of 2013. Accordingly, no
revenue was recognized since the conclusion of the contract. For
the three and six months ended June 30, 2013, the Company
recognized $0.4 million and $2.2 million, respectively, as revenue
under this agreement.</p>

In November 2012, the Company entered into an agreement for a
collaborative research project partially funded by the E.U. Health
Innovation. The agreement provides for approximately $2.5 million
for research in certain development and study related activities
for a DMD therapeutic. For each of the three months ended June
30, 2014 and 2013, the Company recognized less than $100 thousand
as revenue under this agreement. For the six months ended June
30, 2014 and 2013, the Company recognized $1.4 million and less
than $100 thousand, respectively, as revenue under this agreement.
The majority of the revenue under this contract has been recognized
as of June 30, 2014 and only revenue for contract
finalization, if any, is expected in the future.</p>

On April 29, 2014, the Company sold 2,650,000 shares of common
stock at an offering price of $38.00 per share. The Company
received aggregate net proceeds of approximately $94.5 million,

                In
June 2014, the Financial Accounting Standards Board
(“FASB”) issued Accounting Standards Update
(“ASU”) No. 2014-12 which requires that companies
that issue stock-based awards treat a performance target that
affects vesting and that could be achieved after the requisite
service period as a performance condition. ASU No. 2014-12 is
effective for fiscal years after December 15, 2015, with early
adoption permitted. The Company has elected to adopt this ASU early
but does not expect the adoption of this guidance to have a
material effect on its consolidated financial statements as the
performance targets of the Company’s stock-based awards with
performance conditions must be achieved prior to the end of the
requisite service period.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 8%">
In June 2014, the FASB issued ASU No. 2014-10, which
eliminates the concept of a development stage entity
(“DSE”), in its entirety from U.S. GAAP. Under
existing guidance, DSEs are required to report incremental
information, including inception-to-date financial information, in
their financial statements. A DSE is an entity devoting
substantially all of its efforts to establishing a new business and
for which either planned principal operations have not yet
commenced or have commenced but there have been no significant
revenues generated from that business. Entities classified as
DSEs will no longer be subject to these incremental reporting
requirements after adopting ASU No. 2014-10. ASU
No. 2014-10 is effective for fiscal years beginning after
December 15, 2014, with early adoption
permitted. Retrospective application is required for the
elimination of incremental DSE disclosures. Prior to the
issuance of ASU No. 2014-10, the Company had met the
definition of a DSE since its inception. The Company has elected to
adopt this ASU early and, therefore, has eliminated the incremental
disclosures previously required of DSEs, starting with this
Quarterly Report on Form 10-Q.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 8%">
In May 2014, the FASB issued ASU No. 2014-09, which
amends the guidance for accounting for revenue from contracts with
customers. This ASU supersedes the revenue recognition
requirements in Accounting Standards Codification Topic 605,
<i>Revenue Recognition,</i> and creates a new Topic 606, <i>Revenue
from Contracts with Customers</i>. Under the new guidance, a
company is required to recognize revenue when it transfers goods or
renders services to customers at an amount that it expects to be
entitled to in exchange for these goods or services. This guidance
is effective for fiscal years beginning after December 15,
2016, with early adoption not permitted. Two adoption methods
are permitted: retrospectively to all prior reporting periods
presented, with certain practical expedients permitted; or
retrospectively with the cumulative effect of initially adopting
the ASU recognized at the date of initial application. The Company
has not yet determined which adoption method it will utilize or the
effect that the adoption of this guidance will have on its
consolidated financial statements.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 8%">
In April 2014, the FASB issued ASU No. 2014-08, which
amends guidance for reporting discontinued operations and disposals
of components of an entity. The amended guidance requires that
a disposal representing a strategic shift that has (or will have) a
major effect on an entity’s operations and financial results
or a business activity classified as held for sale should be
reported as discontinued operations. The amendments also
expand the disclosure requirements for discontinued operations and
add new disclosure requirements for individually significant
dispositions that do not qualify as discontinued
operations. This guidance is effective prospectively for
fiscal years beginning after December 15, 2014 (early adoption
is permitted only for disposals that have not been previously
reported). The Company does not expect the adoption of this
guidance to have a material effect on its consolidated financial
statements.</p>

Basic net loss per share is computed by dividing net loss by the
weighted-average number of shares of common stock outstanding.
Diluted net loss per share is computed by dividing net loss by the
weighted-average number of shares of common stock and dilutive
common stock equivalents outstanding. Given that the Company
recorded a net loss 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, excluded from the diluted net loss per share
calculation.</p>

Sarepta 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 its 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 developing therapeutics for the
treatment of infectious diseases.</p>

The Company has not generated any material revenue from product
sales to date and there can be no assurance that revenue from
product sales will be achieved. Even if the Company does achieve
revenue from product sales, it is likely to continue to incur
operating losses in the near term.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
As of June 30, 2014, the Company had $284.2 million of cash,
cash equivalents and investments, consisting of $102.8 million of
cash and cash equivalents, $176.8 million of short-term investments
and $4.6 million of restricted investments. The Company believes
that its balance of cash, cash equivalents and investments is
sufficient to fund its current operational plan for the next twelve
months. The government contract under which the Marburg drug
candidate was being developed expired in July 2014 and the Company
is currently evaluating options to continue advancing its Marburg
candidate and other infectious disease research and development
efforts. The Company may pursue additional cash resources through
public or private financings, seek additional government contracts
and establish collaborations with or license its technology to
other companies.</p>

The accompanying unaudited condensed consolidated financial

principles generally accepted in the United States of America
(“U.S. GAAP”), reflect the accounts of Sarepta
Therapeutics, Inc. and its wholly-owned subsidiaries. All
intercompany transactions between and among its consolidated

others. The information included in this quarterly report on Form

The preparation of the unaudited condensed consolidated financial
statements in conformity with U.S. GAAP requires management to make
estimates and assumptions that affect the reported amounts of
assets, liabilities, equity, revenue, expenses and the disclosure
of contingent assets and liabilities. 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.</p>

<b><i>Reclassification</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
The Company has revised the presentation as well as the caption of
certain current liabilities within the unaudited condensed
consolidated balance sheets to conform to the current period
presentation. “Accrued liabilities” of $9.6 million as
of December 31, 2013 is reclassified from “accounts
payable” and grouped with “accrued employee
compensation” of $5.0 million. “Accrued
liabilities” and “accrued employee compensation”
are presented as “accrued expenses” on the unaudited
condensed consolidated balance sheets. This revision had no impact
on total current liabilities or total liabilities.</p>

On May 22, 2014, the Company entered into a Purchase and Sales
Agreement with Eisai, Inc. to acquire certain real and personal
property located in Andover, Massachusetts. The aggregate purchase
price, including certain fees and taxes is approximately $15.0
million, of which approximately $10.0 million was paid at closing
and the remaining $5.0 million will be paid in two installments by
July 15, 2015 and January 15, 2016. On July 15,
2014, the closing of the purchase of the real and personal property

As of December 31, 2013, the Company had gross deferred tax
assets of $133.6 million primarily from U.S. federal and state net
operating loss (“NOL”) carryforwards, U.S. federal and
state research and development credit carryforwards, stock-based
compensation expense and intangibles. Due to uncertainties
surrounding the Company’s ability to generate future taxable
income to realize these assets, a full valuation allowance has been
established to offset its net deferred tax asset. Additionally, the
Internal Revenue Code rules could limit the future use of the
Company’s NOL and research and development credit
carryforwards to offset future taxable income based on ownership
changes and the value of the Company’s common stock.</p>

The Company’s equity incentive plans allow for the granting
of a variety of stock awards. To date, the Company has granted
stock options, restricted stock awards, restricted stock units and
stock appreciation rights. The fair value of stock awards, with
consideration given to estimated forfeitures, is recognized as
compensation expense on a straight-line basis over the vesting
period of the grants.</p>

The Company has granted stock options with both service- and
performance-based criteria. In general, stock options granted vest
over four years and have a ten-year term. Through the filing of an
Investigational New Drug (“IND”) application during the
period, 20% of performance awards were triggered to be eligible to
vest subject to the remaining service conditions of the awards.
Accordingly, the Company has recognized approximately $0.6 million
in stock-based compensation expense related to the options with
performance-based criteria.</p>

                In
June 2014, the Financial Accounting Standards Board
(“FASB”) issued Accounting Standards Update
(“ASU”) No. 2014-12 which requires that companies
that issue stock-based awards treat a performance target that
affects vesting and that could be achieved after the requisite
service period as a performance condition. ASU No. 2014-12 is
effective for fiscal years after December 15, 2015, with early
adoption permitted. The Company has elected to adopt this ASU early
but does not expect the adoption of this guidance to have a
material effect on its consolidated financial statements as the
performance targets of the Company’s stock-based awards with
performance conditions must be achieved prior to the end of the
requisite service period.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 8%">
In June 2014, the FASB issued ASU No. 2014-10, which
eliminates the concept of a development stage entity
(“DSE”), in its entirety from U.S. GAAP. Under
existing guidance, DSEs are required to report incremental
information, including inception-to-date financial information, in
their financial statements. A DSE is an entity devoting
substantially all of its efforts to establishing a new business and
for which either planned principal operations have not yet
commenced or have commenced but there have been no significant
revenues generated from that business. Entities classified as
DSEs will no longer be subject to these incremental reporting
requirements after adopting ASU No. 2014-10. ASU
No. 2014-10 is effective for fiscal years beginning after
December 15, 2014, with early adoption
permitted. Retrospective application is required for the
elimination of incremental DSE disclosures. Prior to the
issuance of ASU No. 2014-10, the Company had met the
definition of a DSE since its inception. The Company has elected to
adopt this ASU early and, therefore, has eliminated the incremental
disclosures previously required of DSEs, starting with this
Quarterly Report on Form 10-Q.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 8%">
In May 2014, the FASB issued ASU No. 2014-09, which
amends the guidance for accounting for revenue from contracts with
customers. This ASU supersedes the revenue recognition
requirements in Accounting Standards Codification Topic 605,
<i>Revenue Recognition,</i> and creates a new Topic 606, <i>Revenue
from Contracts with Customers</i>. Under the new guidance, a
company is required to recognize revenue when it transfers goods or
renders services to customers at an amount that it expects to be
entitled to in exchange for these goods or services. This guidance
is effective for fiscal years beginning after December 15,
2016, with early adoption not permitted. Two adoption methods
are permitted: retrospectively to all prior reporting periods
presented, with certain practical expedients permitted; or
retrospectively with the cumulative effect of initially adopting
the ASU recognized at the date of initial application. The Company
has not yet determined which adoption method it will utilize or the
effect that the adoption of this guidance will have on its
consolidated financial statements.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 8%">
In April 2014, the FASB issued ASU No. 2014-08, which
amends guidance for reporting discontinued operations and disposals
of components of an entity. The amended guidance requires that
a disposal representing a strategic shift that has (or will have) a
major effect on an entity’s operations and financial results
or a business activity classified as held for sale should be
reported as discontinued operations. The amendments also
expand the disclosure requirements for discontinued operations and
add new disclosure requirements for individually significant
dispositions that do not qualify as discontinued
operations. This guidance is effective prospectively for
fiscal years beginning after December 15, 2014 (early adoption
is permitted only for disposals that have not been previously
reported). The Company does not expect the adoption of this
guidance to have a material effect on its consolidated financial
statements.</p>

In June 2013, the Company entered into a lease agreement for its
headquarters located in Cambridge, Massachusetts. The agreement
calls for a security deposit in the form of a letter of credit
totaling $0.6 million. The Company purchased a certificate of
deposit (“CD”) to meet the requirement and it was
recorded as a long-term restricted investment in the unaudited
condensed consolidated balance sheets as of June 30, 2014. The
initial term of the lease agreement is for seven years with an
average annual base rent of approximately $2.4 million.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In November 2013, the Company entered into the first amendment of
its lease agreement for its headquarters located in Cambridge,
Massachusetts. The amendment modified the original lease to add an
additional 15,077 square feet to its original space, increasing its
total rental space for its headquarters to 61,453 square feet. The
amendment calls for additional annual base rent of approximately
$0.5 million, subject to a 2.5% annual increase. In January 2014,
the Company entered into an agreement to sublease the 15,077 square

In June 2014, the Company entered into an agreement to sublease

all leases totaled $2.0 million and $1.3 million, respectively. The
aggregate non-cancelable future minimum payments under leases were
as follows:</p>

<b><i>Royalty Obligations</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
The Company has 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. For each of the three and six months ended
June 30, 2014 and 2013, royalty payments under these
agreements were less than $100 thousand.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
The Company is also obligated to pay royalties upon the net sales
of DMD products. The royalty rates are in the low to mid-
single-digit percentages for both inside and outside the United
States. For example, under the agreement with Charley’s Fund,
Inc. signed in October 2007, the Company is obligated to pay 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. In May 2003, the Company entered into a
collaboration and license agreement with Ercole Biotechnology, Inc.
and Isis Pharmaceuticals, Inc. (“Isis-Ercole”). The
range of percentage of royalty payments under this agreement,
should such payments ever be made, is from a fraction of a percent
to mid-single-digit percentages.</p>

The Company has license agreements for which it is obligated to pay
development and commercial milestones as a product candidate
proceeds from the filing of an IND application through approval for
commercial sale. There were no significant milestone payments under
these agreements for the three or six months ended June 30,
2014 and 2013, respectively.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
Under the collaboration and license agreement with Isis-Ercole, the
Company may be obligated to make up to $23.4 million in milestone
payments. As of June 30, 2014, the Company has not made any
payments under this 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. 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 June 30, 2014,
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.</p>

In April 2013, the Company and the University of 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
up-front, development and commercial milestone payments. For the
three and six months ended June 30, 2014 and 2013, the Company
recognized $0 and $1.0 million, respectively, relating to certain
up-front payments required under the agreement as research and
development expense in the unaudited condensed consolidated
statement of operations and comprehensive loss.</p>

In March 2014, the Company entered into a patent assignment
agreement with a group of scientists (collectively,
“Assignors”). Under the terms of the agreement, the
Assignors transferred to the Company all rights, title and interest
in certain patent rights as well as technical information related
to the patents. The Company may be obligated to make up to $2.7
million in development and commercial milestone payments. For the
three and six months ended June 30, 2014, the Company recorded
$0 and $0.3 million, respectively, relating to an up-front payment

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, 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 and January 29, 2014.
The complaints were consolidated into a single action (<i>Corban v.
Sarepta, et. al.</i>, No. 14-cv-10201) by order of the court
on June 23, 2014, and plaintiffs were afforded 28 days to file
a consolidated amended complaint. Plaintiffs’
consolidated amended complaint, filed on July 21, 2014, seeks
to bring claims on behalf of themselves and persons or entities
that purchased or acquired securities of the Company between
July 10, 2013 and November 11, 2013. The
consolidated amended complaint alleges that Sarepta and certain of
its officers violated the federal securities laws in connection
with disclosures related to eteplirsen, the Company’s lead
therapeutic candidate for DMD, and seeks damages in an unspecified
amount. Pursuant to the court’s June 23, 2014
order, Sarepta intends to file a motion to dismiss the consolidated
amended complaint on or before August 18, 2014. 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.</p>

In February 2013, the Company issued two letters of credit totaling
$7.3 million to a contract manufacturer in connection with certain
manufacturing agreements. The obligations secured by the letters of
credit are fulfilled upon payment for certain minimum volume
commitments and construction milestones. To meet the requirement of
the letters of credit, the Company purchased $7.3 million in CDs.
One CD in the amount of $3.3 million was released and matured
during the second quarter of 2014 and the other in the amount of
$4.0 million with a July 2014 maturity date was recorded as a
restricted investment in the unaudited condensed consolidated
balance sheets as of June 30, 2014. If the minimum volume
commitments have not occurred when the CD matures, the letter of
credit will be extended.</p>

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 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 three and six months ended June 30, 2014 and 2013, warrants, stock options, restricted stock awards, restricted stock units and stock appreciation rights to purchase approximately 5,905,867 and 6,788,000 shares of common stock were excluded from the net loss per share calculation, respectively, as their effect would have been anti-dilutive.
The expected volatility is estimated using implied volatility in exchange-traded options associated with the Company's common stock.
