&lt;/table&gt;
&lt;p style="PADDING-BOTTOM: 0px; MARGIN-TOP: 6px; MARGIN-BOTTOM: 0px"&gt;
&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In January
2012, the Company entered into a License and Development Agreement
(the &amp;#x201C;Endo Agreement&amp;#x201D;) with Endo pursuant to which the
Company granted to Endo an exclusive commercial world-wide license
to develop, manufacture, market and sell the Company&amp;#x2019;s
BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
Buprenorphine product and to complete U.S. development of such
product candidate for purposes of seeking FDA approval.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px; FONT-SIZE: 1px"&gt;
&amp;#xA0;&lt;/p&gt;
&lt;p style="PADDING-BOTTOM: 0px; MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px"&gt;
&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Pursuant to the
Endo Agreement, Endo has obtained all rights necessary to complete
the clinical and commercial development of BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
Buprenorphine and to sell the product worldwide. Although Endo has
obtained all such necessary rights, the Company has agreed under
the Endo Agreement to be responsible for the completion of certain
clinical trials regarding BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
Buprenorphine (and providing clinical trial materials for such
trials) necessary to submit a New Drug Application
(&amp;#x201C;NDA&amp;#x201D;) to the FDA in order to obtain approval of
BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
Buprenorphine in the U.S., in each case pursuant to a development
plan set forth in the Endo Agreement (as it may be amended pursuant
to the Endo Agreement). The Company is responsible for development
activities through the filing of the NDA in the U.S., while Endo is
responsible for the development following the NDA submission as
well as the manufacturing, distribution, marketing and sales of
BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
Buprenorphine on a worldwide basis. In addition, Endo is
responsible for all filings required in order to obtain regulatory
approval of BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
Buprenorphine.&lt;/font&gt;&lt;/p&gt;
&lt;p style="PADDING-BOTTOM: 0px; MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;
&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Pursuant to the
Endo Agreement, the Company has received (or is expected to receive
upon satisfaction of applicable conditions) the following payments
(some portion(s) of which will be utilized by the Company to
support its development obligations under the Endo Agreement with
respect to BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;

milestones aggregating $35 million in potential milestone payments,
including $15 million upon issuance of a certain patent covering
the product, which was received May 2012), (ii)&amp;#xA0;clinical

&lt;/tr&gt;
&lt;/table&gt;
&lt;p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company has assessed
its arrangement with Endo and the Company&amp;#x2019;s deliverables
thereunder at inception to determine: (i)&amp;#xA0;the separate units
of accounting for revenue recognition purposes, (ii)&amp;#xA0;which
payments should be allocated to which of those units of accounting
and (iii)&amp;#xA0;the appropriate revenue recognition pattern or
trigger for each of those payments. The assessment requires
subjective analysis and requires management to make judgments,
estimates and assumptions about whether deliverables within
multiple-element arrangements are separable and, if so, to
determine the amount of arrangement consideration to be allocated
to each unit of accounting.&lt;/font&gt;&lt;/p&gt;
&lt;p style="PADDING-BOTTOM: 0px; MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;
&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;At the
inception of the Endo arrangement and in accordance with the
revenue recognition criteria under ASC Topic 605, the Company
determined that the Endo Agreement is a multi-deliverable
arrangement under ASC Topic 605 with three deliverables:
(1)&amp;#xA0;the license rights related to BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
Buprenorphine, (2)&amp;#xA0;services related to obtaining enhanced
intellectual property rights through the issuance of a particular
patent and (3)&amp;#xA0;clinical development services. The Company
concluded that the license delivered to Endo at the inception of
the Endo Agreement has stand-alone value under ASC 605-25 because
Endo obtained, at the inception of the Endo Agreement, all of the
rights and knowledge necessary to fully exploit its license without
the Company&amp;#x2019;s further involvement. It was also determined
that there was a fourth deliverable, the provision of clinical
trial material (&amp;#x201C;CTM&amp;#x201D;). The amounts involved are,
however, immaterial and delivered in essentially the same time
frame as the clinical development services. Accordingly, the
Company has not separately accounted for the CTM deliverable, but
considers it part of the clinical development services
deliverable.&lt;/font&gt;&lt;/p&gt;
&lt;p style="PADDING-BOTTOM: 0px; MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;
&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The initial
non-refundable $30 million license fee was allocated to each of the
three deliverables based upon their relative selling prices using
best estimates. The analysis of the best estimate of the selling
price of the deliverables was based on the income approach, the
Company&amp;#x2019;s negotiations with Endo and other factors, and was
further based on management&amp;#x2019;s estimates and assumptions which
included consideration of how a market participant would use the
license, estimated market opportunity and market share,
Company&amp;#x2019;s estimates of what contract research organizations
would charge for clinical development services, the costs of
clinical trial materials and other factors. Also considered were
entity specific assumptions regarding the results of clinical
trials, the likelihood of FDA approval of the subject product and
the likelihood of commercialization based in part on the
Company&amp;#x2019;s prior agreements with the BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
technology&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Based on this analysis,
$15.6 million of the up-front license fee was allocated to the
license (which was estimated to have a value significantly in
excess of $30 million), and $14.4 million to&amp;#xA0;clinical
development services (which is inclusive of the cost of
CTM).&amp;#xA0;Although the intellectual property component was
considered a separate deliverable, no distinct amount of the
up-front payment was assigned to this deliverable because the
Company determined the deliverable to be perfunctory. In April
2012, the patent being sought by the Company was granted as
described further below, and in May 2012, the applicable
intellectual property milestone payment of $15 million was received
and recognized as revenue. The amount allocated to the license was
recognized as revenue in January 2012.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The portion of the upfront
license fee allocated to the clinical development services
deliverable ($14.4 million) is being recognized as those services
are performed.&amp;#xA0;The Company estimates that such clinical
development services will extend into early 2014.&amp;#xA0;Based on the
estimated proportion of those services performed through
June&amp;#xA0;30, 2013, $5.2 million was recognized as revenue in
fiscal year 2012 and $3.4 million was recognized as revenue during
the first six-months of 2013. As a result, $5.9 million remains
deferred at June&amp;#xA0;30, 2013.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Company analyzed the
milestone payments noted above in accordance with ASC 605-28 to
determine if such milestones are substantive. This determination
included an analysis of the Company&amp;#x2019;s performance to achieve
each milestone, the enhancement of value of the delivered items,
the timing of performance related to the milestone, and the
reasonability of the milestone relative to all the deliverables and
payment terms. The Company concluded that each of the milestones is
substantive under the guidance in ASC 605-28.&lt;/font&gt;&lt;/p&gt;
&lt;p style="PADDING-BOTTOM: 0px; MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;
&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The term of the
Endo Agreement shall last, on a country-by-country basis, until the
later of: (i)&amp;#xA0;10 years from the date of the first commercial
sale of BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
Buprenorphine in a particular country or (ii)&amp;#xA0;the date on
which the last valid claim of the Company&amp;#x2019;s patents covering
BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
Buprenorphine in a particular country has expired or been
invalidated. The Endo Agreement shall be subject to termination:
(i)&amp;#xA0;by Endo, at any time, upon a specific amount of prior
written notice to the Company, (ii)&amp;#xA0;by Endo and the Company
upon mutual written agreement, (iii)&amp;#xA0;by either party upon a
material default or breach of the Endo Agreement and such default
or breach is not cured within a specified timeframe, (iv)&amp;#xA0;the
voluntary or involuntary bankruptcy of either party or (v)&amp;#xA0;by
the Company if Endo does not meet certain diligence obligations
outside of the United States.&lt;/font&gt;&lt;/p&gt;
&lt;p style="PADDING-BOTTOM: 0px; MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;
&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;On
February&amp;#xA0;16, 2012, the Company announced that the U.S. Patent
and Trademark Office issued a Notice of Allowance regarding its
patent application (No. 13/184306), which patent will extend the
exclusivity of the BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
drug delivery technology for the Company&amp;#x2019;s BEMA&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;
Buprenorphine and BUNAVAIL&lt;/font&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="1"&gt;&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;TM&lt;/sup&gt;&lt;/font&gt;
&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;product
candidates from 2020 to 2027. On April&amp;#xA0;17, 2012, the Company
announced that this patent was granted. As a result, pursuant to
the Endo Agreement, the Company received a milestone payment from
Endo in the amount of $15 million in May 2012. As discussed above,
this milestone had been evaluated to be a substantive milestone
under ASC 605-28, and therefore was recognized as revenue when the
milestone was received.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The remaining milestone
payments are expected to be recognized as revenue as and if they
are achieved, except that one milestone is contingently refundable
for a period of time. Revenue related to that milestone is expected
to be recognized as refund provisions as defined in the agreement
expire. Sale threshold payments and sales-based royalties will be
recognized as they accrue under the terms of the Endo
Agreement.&lt;/font&gt;&lt;/p&gt;
