11. Article X, Funding, is amended to read as follows in its entirety:

(a) Except for Board Members, Officers and their Spouses, the Plan shall be funded all or in part by contributions from Participants and their Covered Dependents.

(b) Former Executives, Outside Directors and their Covered Dependents may be required to pay the same amount as an eligible employee pays for coverage under the Sponsor's group medical plan or the full cost of coverage without any subsidy as set forth in a written agreement between the Former Executive or the Outside Director and the Sponsor or other Employer. In the absence of such an agreement, the Former Executive, the Outside Director or the surviving Spouse of a Former Executive or Outside Director shall:

(i) make payments in the same amount that a full-time regular employee would pay for comparable coverage under the Sponsor's group medical plan for a period of ten (10) years or, if less, the coverage period; and

(ii) on and after the tenth anniversary of participation in the Plan, make payments in an amount equal to the cost of coverage that would satisfy the premium requirements of Code section 4980B(f)(4) and ERISA section 604 and described in Section 9.5 above.

(c) The Plan shall become the secondary payer and Medicare shall become the primary payer of medical expenses incurred by a Former Executive (and the Spouse of a Former

6

Executive) as of the date that the Former Executive (and, when applicable, the Spouse of a Former Executive) attains the age of 65 years until such time as the Former Executive's (or the Spouse's) participation in this Plan terminates.

(d) In the case of a Board Member, an Officer or a Spouse of a Board Member or Officer, notwithstanding anything in the Plan or any other agreement to the contrary, the Sponsor will pay (i) all of the cost of all of the Plan's benefits and coverages for that individual for that individual's lifetime and (ii) to the individual, an additional sum in the amount necessary to reimburse such individual for any federal income tax liability resulting from (or associated with) the Sponsor's payments to or for the benefit of the individual under this Plan, so that the benefits and coverages under this Plan for that individual are provided at no cost to that individual.

(d) The Employers shall have no obligation, but shall have the right, to establish a special trust or fund out of which benefits shall be paid. The Employers shall have no obligation, but shall have the right, to reinsure, or to purchase any type of additional coverage with respect to any benefits under the Plan. To the extent the Employer elects to purchase insurance for any benefits under the Plan, any such benefits shall be the sole responsibility of the insurer, and the Employer shall have no responsibility for the payment of such benefits (except for refunding any Participant contributions that were not remitted to an insurer).

12. Article XII, Section 12.1, is amended to add the following new penultimate sentence to read as follows:

"Notwithstanding the preceding sentence to the contrary, the Sponsor may amend the elections, coverages or benefits available, or the terms and conditions of the Plan that affect Former Executives, Outside Directors and their Covered Dependents even if the effect of the amendment is to reduce coverages or benefits or decrease the number or class of individuals who may be Participants or Covered Dependents unless otherwise prohibited by the terms and conditions in a separate written agreement between the Sponsor and the Former Executive or the Outside Director and his or her Covered Dependents, in which case such amendment shall be effective only with the written consent of the Former Executive or the Outside Director and, if required, the Former Executive's or the Outside Director's Spouse."

7

13. Article XII, Section 12.2, is amended to permit the Sponsor to terminate or discontinue the Plan without the need to obtain the express, prior written consent of any Participant who is a Former Executive, an Outside Director or the Covered Dependents of a Former Executive or an Outside Director and reads as follows:

"12.2 Termination of Plan. The Sponsor may terminate or discontinue this Plan at any time, if necessary, only by a written instrument signed by its authorized officer and only with the express, prior written consent of all Participants and Covered Dependents (other than Former Executives, Outside Directors or their Covered Dependents) at the effective date of the termination or discontinuation. For the avoidance of doubt, the Sponsor may terminate or discontinue the Plan at any time without the consent of any Former Executive or Outside Director, or the Covered Dependents of any Former Executive or Outside Director unless otherwise prohibited by the terms and conditions in a separate written agreement between the Sponsor and the Former Executive or the Outside Director and his or her Covered Dependents, in which case such termination shall be effective only with the written consent of the Former Executive or the Outside Director and, if required, the Former Executive's or the Outside Director's Spouse. Notwithstanding anything in the Plan to the contrary, coverages and benefits provided under this Plan are to be continued for the life of each Board Member, each Officer and each Spouse of a Board Member and Officer, and the Plan and the Sponsor's obligations under the Plan may not be terminated or discontinued without the express, prior written consent of each Board Member, Officer and their Spouses. Upon termination or discontinuance of the Plan as permitted by this Section, all elections shall terminate, and reimbursements or payments of Qualified Medical Expenses shall be made only in accordance with Article 11."

14. The provisions of Sections 13.11 shall not apply to Former Executives, Outside Directors or their Covered Dependents.
15. Except as expressly modified by this Amendment Four, all other terms and conditions of the Plan, as amended, shall remain in full force and effect; provided, however, other provisions in the Plan shall be deemed to be amended to permit Former Executives (and their Dependents) to be afforded medical coverage under the Plan to the extent necessary.
