        <footnote id="F1">On May 5, 2004, the Issuer acquired Chembio Diagnostic Systems Inc., a privately held corporation (&quot;Chembio&quot;), through a merger of a wholly owned subsidiary of the Issuer with and into Chembio.  Pursuant to the terms of the merger, each stockholder of Chembio received shares of the Issuer's Common Stock in exchange for Chembio common stock owned.  The Issuer also assumed all the outstanding warrants and options to acquire Chembio common stock.  Each assumed warrant and option is now exercisable for shares of the Issuer's Common Stock.  Mr. Pelossof received 225,554 shares of the Issuer's Common Stock in exchange for his Chembio common stock and received warrants to purchase 22,555 shares of the Issuer's Common Stock and options to purchase 100,000 shares of the Issuer's Common Stock in exchange for warrants and options, respectively, that he held of Chembio.</footnote>
