&lt;p style="MARGIN-TOP: 6px; MARGIN-BOTTOM: 0px"&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In 2009, as part of a
settlement arrangement, the Company received a warrant from
Accentia Biopharmaceuticals, Inc., a related party
(&amp;#x201C;Accentia&amp;#x201D;), to purchase 2&amp;#xA0;million shares of
common stock of Biovest International, Inc. (&amp;#x201C;Biovest&amp;#x201D;)
held by Accentia. Biovest is a majority-owned subsidiary of
Accentia. During the six months ending June&amp;#xA0;30, 2013, Biovest
filed a voluntary petition for relief under Chapter 11 of the
United States Bankruptcy Code with the United States Bankruptcy
Court. On July&amp;#xA0;9, 2013, the plan became effective, which
canceled all outstanding common stock. As a result, the warrants
had no value as of June&amp;#xA0;30, 2013 and the reduction of value is
included in derivative gain (loss) in the condensed consolidated
statement of operations for the three and six months ended
June&amp;#xA0;30, 2013.&lt;/font&gt;&lt;/p&gt;
