Other Participant Goal Performance Score to an Award Percentage using the
conversion table included on Exhibit A, resulting in a Final Score] (for

incentive compensation will be paid hereunder.

  o   The maximum total incentive compensation that you can earn hereunder is an
amount equal to 150% of your Target Award.

        Unless the Committee, in its discretion, determines otherwise, your
rights to receive the bonus will be forfeited if you are not still an employee
of the Company on December 31, 2005. Consistent with the terms of the Plan, the
Committee may adjust the bonus payment amount if it deems an extraordinary
reason exists. Notwithstanding anything else herein, no incentive compensation
earned hereunder shall be paid until formally approved by the Committee. The
Company will withhold an appropriate amount from the bonus for the payment of
all applicable withholding taxes.
