        <footnote id="F3">The number of shares is based on the initial conversion price of $.65. The conversion price is subject to adjustment.  For purposes of determining the number of shares of common stock upon conversion, the value of the convertible preferred stock will be increased by the amount of dividends at a rate of 6% per annum, which will be cumulative and accrue daily from the date of issuance on the $1,000 stated value. The conversion of the Series A convertible preferred stock, and exercising of the warrants are restricted to the extent that, upon such conversion or exercise, the number of shares of common stock then beneficially owned by the holder of such securities and its affiliates would exceed 4.99% of the total number of shares of common stock then outstanding.</footnote>
