The proceeds from such an offering received from sources other than the reporting persons will be used to repay these notes.  The reporting persons are required to use the balance of the notes to participate in the rights offering. (Continued in Note 2)</footnote>
        <footnote id="F2">Any of these notes not repaid or otherwise used by the reporting persons to subscribe for common stock in such rights offering will be automatically converted into common stock at the earlier of (1) the closing of the rights offering (or such other equity offering of the issuer) or (2) June 30, 2010, at a price per share equal to (A) the price per share offered in the rights offering (or such other equity offering of the issuer) or (B) if no rights offering (or other equity offering) occurs before June 30, 2010, $0.4302, which reflects the volume weighted average sale price for the common stock as quoted on the OTC Bulletin Board for the ten trading days prior to the issuance of these notes.</footnote>
