The Committee may, in its discretion, reduce or eliminate the amount of any Award payable to any Participant, based on such factors as the Committee may deem relevant, but the Committee may not increase the amount of any Award payable to any Participant above the amount established in accordance with Section 6 (a) of the Plan. For purposes of clarity, the Committee may exercise the discretion provided for by the foregoing sentence in a non-uniform manner among Participants.

The Company shall pay Awards as soon as administratively practical following certification by the Committee of the extent to which the applicable Performance Targets have been achieved and the determination of the actual Awards in accordance with Section 4 and this Section 6; provided that in no event shall any Award (or any other amount payable pursuant to this Plan) be paid later than the fifteenth (15) day of the third month following the end of the fiscal year with respect to which Award (or such other amount) was earned, if at all.  A Participant must be employed by the Company on the last date of the Performance Period to receive an Award.  Notwithstanding the foregoing, paymen t of Awards shall be subject to any election duly and validly made in accordance with Section 409A of the Code by a Participant with respect to the deferral of all or a portion of his or her Award under a deferred compensation plan of the Company.
