&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;The ANDA procedure and the 505(b)(2)&amp;#160;NDA procedure include provisions allowing generic manufacturers to challenge the effectiveness of the innovator&amp;#8217;s patent protection long before the generic manufacturer actually commercializes their products through the paragraph IV certification procedure. In recent years, generic manufacturers have used paragraph&amp;#160;IV certifications extensively to challenge patents on a wide array of innovative pharmaceuticals, and we expect this trend to continue and to implicate drug products with even relatively small total revenues.&lt;/font&gt;&lt;/p&gt;

While the Company attempts to protect its proprietary information as trade secrets effectively, the Company cannot guarantee that the measures it has taken will provide effective protection for its proprietary information. It is possible that the Company&amp;#8217;s competitors will independently develop products that compete with TESTOPEL and Edex and certain other of its products.&lt;/font&gt;&lt;/p&gt;

&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;In October&amp;#160;2008, the Company and its licensor, CPEX Pharmaceuticals,&amp;#160;Inc. (FCB I LLC&amp;#8217;s (&amp;#8220;FCB&amp;#8221;) predecessor in interest to Testim), received notice that Upsher-Smith filed an ANDA containing a paragraph IV certification seeking approval from the FDA to market a generic version of Testim prior to the January&amp;#160;2025 expiration of the &amp;#8216;968 Patent. Shortly after, the Company commenced the Delaware Upsher-Smith ANDA Litigation.&amp;#160; Although it would seem unlikely based on (i)&amp;#160;the FDA&amp;#8217;s public statements in its responses to the Citizen&amp;#8217;s Petitions submitted by each of the Company and AbbVie Inc. (&amp;#8220;AbbVie&amp;#8221;) and (ii)&amp;#160;Upsher-Smith&amp;#8217;s public stance that its generic product has different penetration enhancers than Testim, the FDA could approve the generic product proposed in Upsher-Smith&amp;#8217;s ANDA. With FDA approval, even if the Delaware Upsher-Smith ANDA Litigation remains pending, Upsher-Smith may nevertheless choose to launch this generic product at risk of infringing the &amp;#8216;968 patent.&amp;#160; Although administratively closed in December&amp;#160;2011, the Delaware Upsher-Smith ANDA Litigation has not been dismissed or finally resolved and could also result in a finding that Upsher-Smith&amp;#8217;s proposed testosterone product does not infringe the &amp;#8216;968 Patent or that the &amp;#8216;968 Patent is invalid and/or unenforceable.&amp;#160; All discovery obligations of the parties continue to be in effect.&amp;#160;&amp;#160; In April&amp;#160;2012, the Company and FCB received a notice from Upsher-Smith in connection with its ANDA advising the Company and FCB of Upsher-Smith&amp;#8217;s Paragraph IV certification relating to the eight additional patents listed in the Orange Book in addition to the &amp;#8216;968 patent-in-suit, and asserting that Upsher-Smith does not believe that the product for which it is seeking approval infringes any of the Orange Book listed Testim patents and that those patents are invalid.&amp;#160; A tenth U.S. patent issued to FCB on May&amp;#160;15, 2012 and was listed in the Orange Book.&lt;/font&gt;&lt;/p&gt;

&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;On or about December&amp;#160;28, 2012, the Company and FCB became aware of a notice from Upsher-Smith that advised the Company and FCB of Upsher-Smith&amp;#8217;s filing of a 505(b)(2)&amp;#160;NDA containing a Paragraph IV certification under 21 U.S.C. Section&amp;#160;314.52(c)&amp;#160;for testosterone gel (the &amp;#8220;Upsher-Smith NDA&amp;#8221;). This Paragraph IV certification notice refers to the ten U.S. patents, covering Testim, that are listed in the Orange Book.&amp;#160; These ten patents are owned by FCB and are exclusively licensed to Auxilium and will expire between 2023 and 2025.&amp;#160; Upsher-Smith may seek to have any drug approved under the Upsher-Smith NDA as a generic or branded generic version of Testim.&amp;#160; On January&amp;#160;28, 2013, the Company and FCB filed a lawsuit in the United States District Court for the District of Delaware against Upsher-Smith for infringement of FCB&amp;#8217;s ten patents listed in the Orange Book as covering Testim&amp;#174; 1% testosterone gel.&amp;#160; A hearing on Upsher-Smith&amp;#8217;s previously filed motion for summary judgment was held on June&amp;#160;28, 2013, and by request of the Court, the parties submitted additional briefing in the weeks following the hearing.&amp;#160; The Company is currently awaiting a ruling from the Court which the Company believes could come as early as during the third quarter of 2013.&amp;#160;&amp;#160; If summary judgment is granted, Upsher-Smith could launch a 1% testosterone gel product using Testim as the reference drug immediately after such ruling, if it receives approval by the FDA.&amp;#160; If summary judgment is not granted, the trial is currently scheduled to commence in June&amp;#160;2014.&lt;/font&gt;&lt;/p&gt;

&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;On March&amp;#160;26, 2013, the Company submitted a Citizen&amp;#8217;s Petition to the FDA with respect to Upsher-Smith&amp;#8217;s 505(b)(2)&amp;#160;NDA referencing Testim.&amp;#160; The Company requested that, in the event of FDA approval of the Upsher-Smith 505(b)(2)&amp;#160;NDA, the FDA: (i)&amp;#160;refrain from designating Upsher-Smith&amp;#8217;s testosterone gel as therapeutically equivalent to Testim and (ii)&amp;#160;require that the label for the Upsher-Smith testosterone gel state that the product is not interchangeable with other testosterone transdermal gels.&amp;#160; Since any such approval by the FDA would be pursuant to a 505(b)(2)&amp;#160;NDA and not pursuant to an ANDA, it is unclear at this time whether such an Upsher-Smith product would receive a therapeutically equivalent rating to Testim or a different rating.&lt;/font&gt;&lt;/p&gt;

(NV) regarding its filing with the FDA of an ANDA for a generic 1% testosterone gel product.&amp;#160; This letter also stated that the ANDA contained Paragraph IV certifications with respect to the nine patents listed in the Orange Book on that date as covering Testim.&amp;#160; The Company&amp;#8217;s lawsuit filed against Watson involves those nine patents, as well as a tenth patent covering Testim that was issued on May&amp;#160;15, 2012 and is listed in the Orange Book.&lt;/font&gt;&lt;/p&gt;
