        <footnote id="F1">The reporting person, Epic Pharma, LLC (&quot;EP&quot;), is an equity owner of Epic Investments, LLC (&quot;EI&quot;), which owns securities convertible into or exercisable for in excess of 10% of the outstanding shares of common stock of the issuer.  EP and EI are both owned, wholly or in part, and are operated by Ram Potti, Ashok G. Nigalaye and Jeenarine Narine, each of whom is a director of the issuer. The interest of EP in the securities of the issuer owned by EI is limited, and EP disclaims beneficial ownership of such securitieis except, to the extent of its penuniary interest in EI.</footnote>
        <footnote id="F2">This Form 4/A is being filed to correct information included in Table II, Column 9 of the Form 4 originally filed by the reporting person with the SEC on November 5, 2009, in which the reporting person indicated that the total number of warrants it owned were exercisable for an aggregate of 40,000,000 shares of the issuer's common stock.  In fact, the reporting person made an error in addition and Table II, Column 9 should have indicated that the warrants it owns after giving effect to the transaction reported in the Form 4, are exercisable for an aggregate of 80,000,000 shares of the issuer's common stock.</footnote>
