        <footnote id="F1">On 11/24/2003, (a) Fleming US Discovery Fund III, L.P. (US Fund) purchased 464,978 shares of Common Stock in the Issuer's public rights offering at the $1.10 per share price, utilizing the remaining outstanding balance and all accrued interest in the amount of $511,475.42 on unsecured promissory notes held by the US Fund, following an offer by the Issuer to do so, and (b) Fleming US Discovery Offshore Fund III, L.P. (Offshore Fund) purchased 74,548 shares of Common Stock in the Issuer's public rights offering at the $1.10 per share price, utilizing the remaining outstanding balance and all accrued interest in the amount of $82,003.26 on unsecured promissory notes held by the Offshore Fund, following an offer by the Issuer to do so.</footnote>
        <footnote id="F2">The amounts shown represent the direct beneficial ownership of the Issuer's equity securities by the US Fund and the Offshore Fund.  In addition, the other reporting owners on this Form 4 have indirect beneficial ownership interests (as described in footnotes 3, 4, 5 and 6 below).  The US Fund, as the designated reporter, is executing this report on behalf of all reporting owners, each of whom has authorized it to do so.  Each of such persons disclaims beneficial ownership of the securities to the extent it exceeds such person's pecuniary interest therein.</footnote>

(Discovery Partners) because Discovery Partners is the general partner of the US Fund and the Offshore Fund.  The actual pro rata portion of such beneficial ownership that may be deemed to be attributable to J.P. Morgan Chase &amp; Co. is not readily determinable because it is subject to several variables, including the internal rate of return and vesting of interests within the US Fund and the Offshore Fund.</footnote>
