        <footnote id="F1">Pursuant to a Stock Sale Agreement, Mr. Guazzoni purchased the 1,877,984 shares of common stock noted in Table I and the 410,036 options noted in Table II for the aggregate purchase price of $1,080,000.  The parties to the Stock Sale Agreement established the consideration only in the aggregate; therefore, there is no way to divide the purchase price among the value of the shares and the value of the options.</footnote>
