has granted the Optionee options (the "Options") to purchase an aggregate of
98,000 shares of the Company's common stock, $.001 par value per share (the
"Common Stock"), inadvertently in violation of the Plan; and

         WHEREAS, the Board of Directors and the Optionee desire to cancel the
Options in consideration for consideration by the Company, subject to

         NOW, THEREFORE, in consideration of One Dollar ($1.00) and the
foregoing, the mutual promises and agreements hereinafter contained, and for
other good and valuable consideration, the receipt and sufficiency of which are
