subject to the terms and conditions provided herein, and net of reduction for
any applicable withholding taxes.

         2. The Success Bonus shall not be paid if, prior to the closing date of
the Change of Control of the Company, either (i) the Employee has been
terminated by the Company for Cause or (ii) the Employee voluntarily resigns
without good reason.

         3. "Cause" shall mean that (i) Employee shall have committed any act of

notice to the Employee describing the action of Employee constituting the act of
default.

         5. For purposes of this Agreement, voluntary termination for "Good
Reason" shall mean any of the following, unless consented to by Employee in
