         WHEREAS, pursuant to the Employment Agreement, the Executive Employee

         WHEREAS, Executive Employee separated from the Company on September 29,
2002; and

         WHEREAS, both the Company and the Executive Employee wish to rescind
the Stock Purchase Agreement, the Promissory Notes and the Stock Pledge

         NOW, THEREFORE, in consideration of the mutual terms, covenants,
agreements and conditions hereinafter set forth, the Company and Executive
Employee hereby agree as follows:

         1. The Executive Employee hereby agrees to relinquish to the Company

future have or be entitled to, and to promptly return to the Company for
cancellation all certificates representing the Unvested Shares.

         2. The Company and the Executive Employee hereby agree that each of the
Stock Purchase Agreement, as amended, the Promissory Notes and the Stock Pledge
Agreements with respect to the Unvested Shares is hereby rescinded in its
entirety and is no longer in force and effect, without any liabilities to or
obligations of the Company or the Executive Employee.

         3. The Executive Employee agrees to indemnify and hold harmless, the
Company, its respective directors, officers, employees and agents (collectively,
"Person") from and against any and all losses, claims, damages, liabilities and
expenses (including without limitation reasonable attorney fees and

         4. This Agreement shall be governed by and construed in accordance with

shall be due, shall exceed the limits of validity prescribed by law, then the
obligation to be fulfilled or performed shall be reduced to the limit of such
validity; and if any clause or provision contained in this Agreement operates or
would operate to invalidate this Agreement, in whole or in part, then such
clause or provision only shall be held ineffective, as though not herein
contained, and the remainder of this Agreement shall remain operative and in
full force and effect.
