     WHEREAS, in Section 9.7 of the Plan, the Board of Directors of the Company (the “Board”) reserved the discretionary right to amend the Plan at any time; and

     WHEREAS, the Board now desires to amend the Plan to permit Grantees to elect to defer the receipt of Shares payable upon the vesting of Restricted Stock Unit Awards;

     NOW, THEREFORE, effective as December 1, 2009, the Plan is hereby amended by this Second Amendment thereto, as follows:

     1. A new Section 5.2(d) is added to the Plan and the existing Section 5.2(d) is deleted in its entirety:

(d) Initial Deferral of Restricted Stock Unit Awards. As permitted in the discretion of the Committee and subject to such terms and conditions as required by the Committee, a Grantee may elect in writing to defer the receipt of Shares that become payable upon vesting of a Restricted Stock Unit Award; provided, however, that such election be made by the Grantee not later than by the end of the calendar year that immediately precedes the calendar year during which the applicable performance period begins. Notwithstanding the previous sentence, at the discretion of the Committee and subject to such terms and conditions as required by the Committee, a Grantee who is first eligible to participate in the Plan under Section 1.7 may elect in writing to defer receipt of his initial Restricted Stock Unit Award under the Plan within thirty (30) days after the grant date of such Restricted Stock Unit Award. Any deferral election made by the Grantee pursuant to this Section 5.2(d) must be consistent with the requirements of Code Section 409A and shall be construed accordingly.

     2. A new Section 5.2(e) is hereby added to the Plan:

Any subsequent deferral election made by the Grantee pursuant to this Section 5.2(e) must be consistent with the requirements of Code Section 409A and shall be construed accordingly.
