Payment of Shares. After a Performance Period has ended, the holder of a Performance Share shall be entitled to payment of the applicable number of Shares with respect thereto as determined by the Committee. The Committee shall make this determination by first determining the extent to which the performance goals set pursuant to Section 8.2 have been met. It will then determine the applicable percentage to be applied to, and will apply such percentage to the number of Performance Shares to determine the payout to be received by the Participant. In addition, with respect to Performance Shares granted to any Covered Employee, no payout shall be made hereunder except upon written certification by the Committee that the applicable performance goal or goals have been satisfied to a particular extent.
