SECTION 4 - BENEFIT

4.1 SERP Retirement Benefit.

(a) General. This Section 4.1 shall not apply to any executive designated as a Participant after December 31, 2002.

(b) Amount of Benefit. A benefit shall be payable under this SERP to, or on behalf of, each Participant, which benefit shall equal the excess, if any, of (1) over (2), where

(1) equals the aggregate of (i) the benefits that would have been payable to him or her, or on his or her behalf, under the Retirement Plan in the form elected by him or her, or his or her beneficiary, under the terms of the Retirement Plan, absent the limitations of Code Sections 401(a)(17) and 415, plus (ii) his or her “restoration benefits” under the Deferred Compensation Plan; and

(2) equals the aggregate benefits actually payable to him or her, or on his or her behalf, under (i) the Retirement Plan, and (ii) the “restoration benefits” provisions of the Deferred Compensation Plan.

(c) Payment of SERP Retirement Benefit. Distribution of a Participant’s SERP Retirement Benefit shall commence on the later of (a) the 30th business day following the date of his or her separation from service (within the meaning of Section 409A) with the Company or a Subsidiary for any reason whatsoever, including death or retirement, or (b) the date the Participant attains age 55. SERP Retirement Benefits shall be paid in a lump sum, calculated using the actuarial assumptions used for calculating lump sum benefits under the Retirement Plan. Notwithstanding the foregoing, if a Participant separates from service (within the meaning of Section 409A) prior to January 1, 2008, the SERP Retirement Benefit payable to, or on behalf of, a Participant under this Section 4.1 shall be paid as of the same date, in the same benefit payment form and to the same person as his or her benefit under the Retirement Plan, and no payment shall be made to, or on behalf of, such Participant under this Section 4.1 unless a benefit is paid to him or her or on his or her behalf under the Retirement Plan.

4.2 SERP Service and Matching Credit Benefits.

(a) SERP Service Credit Benefit. On and after January 1, 2007, the Company will make a SERP Service Credit on behalf of each eligible Participant for each Year, which will be equal to 2.5% (or such other percentage determined by the Committee prior to such Year) of his or her Excess Compensation. For purposes of this § 4.2(a), an “eligible Participant” for any Year means each executive who is a Participant on January 1 of such year, who had 10 or more “years of service” (as defined under the Savings Plan) as of December 31, 2006. An eligible Participant shall be 100% vested in his or her SERP Service Credit Benefit under this SERP.

(b) SERP Matching Credit Benefit. On and after January 1, 2007, the Company will make a SERP Matching Credit on behalf of each Participant for each Year, which will be equal to 3.5% (or such other percentage determined by the Committee prior to such Year) of his or her Excess Compensation. If a Participant separates from service (within the meaning of Section 409A) with the Company or a Subsidiary before attaining 3 “years of service” (as defined under the Savings Plan), then his or her SERP Matching Credit Benefit under this SERP shall be forfeited to the same extent that such benefit would be forfeited if it were a “company matching contribution” (as defined under the Savings Plan) under the Savings Plan.

(c) SERP Account. Each Participant’s SERP Service and Matching Credits shall be allocated to a bookkeeping account maintained as a part of the Company’s books and records to show as of any date the interest of each Participant in these SERP benefits, which is referred to as such Participant’s SERP account. Deemed interest shall be credited to each such SERP account at the same rate and in the same manner that deemed interest is credited to accounts maintained under the Deferred Compensation Plan. The Company shall furnish a statement to each Participant annually, which shows the deemed SERP account balance at the end of the Year preceding the statement date and, at the Company’s discretion, such other account data as the Company deems appropriate.

(d) Payment of SERP Service and Matching Credit Benefits. The SERP Service and Matching Credit Benefits payable to, or on behalf of, a Participant under this Section 4.2 shall be paid on the later of (a) the 30th business day following the date of his or her

separation from service (within the meaning of Section 409A) with the Company or a Subsidiary for any reason whatsoever, including death or retirement, or (b) the date the Participant attains age 55. SERP Service and Matching Credit Benefits shall be paid in a lump sum; provided, however, each Participant may elect to have his or her SERP Service and Matching Credit Benefits distributed in the same manner as a “retirement distribution” under Section 8.3 of the Deferred Compensation Plan, with such election to be filed with the Committee during the enrollment period established by the Committee, and no later than December 15^th of the Year prior to the Year for which the Participant wishes to make the election effective. Any such election shall apply to the SERP Service and Matching Credit Benefits attributable to services performed during the Year covered by the election, and is irrevocable on the last day of the preceding Year. In the absence of any contrary rule established by the Committee, the distribution election shall remain in effect for SERP Service and Matching Credit Benefits credited to the Participant’s SERP account for a subsequent Year unless revised or revoked during the annual enrollment period for such subsequent Year.

4.3 Offset upon Payment for Amounts Owed to Company. The Committee shall have the right, in its absolute discretion, to withhold at the time of payment of a Participant’s SERP Retirement Benefit, SERP Service Credit Benefit or SERP Matching Credit Benefit, from the amount of such payment, in such proportion and combination as the Committee determines is reasonable, to offset (to the extent permissible under Section 409A) any amount that the Committee determines is owed by a Participant to the Company or a subsidiary of the Company.

SECTION 5 - SOURCE OF BENEFIT PAYMENTS

All benefits payable under the terms of this SERP shall be paid by the Company from its general assets. No person shall have any right or interest or claims whatsoever to the payment of a benefit under this SERP from any person whomsoever other than the Company, and no Participant or beneficiary shall have any right or interest whatsoever to the payment of a benefit under this SERP which is superior in any manner to the right of any other general and unsecured creditor of the Company.

SECTION 6 - NOT A CONTRACT OF EMPLOYMENT

Participation in this SERP shall not grant to any Participant the right to remain an employee for any specific term of employment or in any specific capacity or at any specific rate of compensation.

SECTION 7 - NO ALIENATION OR ASSIGNMENT

A Participant or a beneficiary under this SERP shall have no right or power to alienate, commute, anticipate or otherwise assign at law or equity all or any portion of any benefit otherwise payable under this SERP, and the Committee shall have the right in light of any such action to suspend temporarily or terminate permanently the payment of benefits to, or on behalf of, any Participant or beneficiary who attempts to do so.
