        <footnote id="F1">The 9% convertible debentures were canceled by mutual agreement of the reporting person and JRT Holdings, Inc. JRT received
a non-convertible promissory note in the amount of $20,000 as consideration for the cancellation and is entitled to the
interest accrued on the 9% convertible debentures. The conversion price of the convertible debenture was the lesser of (i)
$2.10 or (ii) 80% of the lowest closing bid price of the common stock for the five trading days immediately preceding the
date of conversion. The debentures were convertible until such time as the principal amounts and interest were paid off.</footnote>
