        <footnote id="F1">The Issuer conducted a public offering of equity securities prior to 12/20/03 for gross proceeds of not less than $2 million (Equity Offering).  In accordance with the terms of the 10% Exchange Notes, such Equity Offering triggered the conversion of the outstanding principal and interest on the 10% Exchange Notes into restricted shares of the Issuer's Common Stock at the then current note conversion rate of $.79.  As of 12/19/03, the outstanding principal and interest on the 10% Exchange Notes held by the Reporting Person was $56,021.29 and thus converted into 70,913 shares of restricted Common Stock.</footnote>
        <footnote id="F2">Reporting Person's spouse is one of seven equal shareholders of a New York corporation known as Catherine &amp; Cathryn, Ltd., which purchased 54,000.  The number of shares reported (7,714) are equal to 1/7 of the shares purchased by the corporation, representing the Reporting Person's spouse's pro-rata interest (1/7) in the corporation.  Reporting Person disclaims beneficial interest in 46,286 shares purchased by the corporation.</footnote>
        <footnote id="F3">The Equity Offering triggered the obligation of the Issuer to issue common stock purchase warrants (Convertible Note Warrants) to holders of the 10% Exchange Notes, exercisable to purchase an amount of shares of the Issuer's Common Stock equal to 10% of the number of shares of Common Stock into which the 10% Exchange Notes were convertible at the time of their issuance, for a period of 5 years from their date of issuance, at an exercise price equal to 110% of the lesser of the conversion rate of the 10% Exchange Notes as of the date of their issuance, or the conversion rate of the 10% Exchange Notes as of the date of the issuance of the Convertible Note Warrants.  Thus, the issuer has issued to the Reporting Person Convertible Note Warrants to purchase 6,420 shares of the Issuer's Common Stock at an exercise price equal to $.87 per share.</footnote>
