Exhibit 10.11 CENTRAL ILLINOIS PUBLIC SERVICE COMPANY SPECIAL EXECUTIVE RETIREMENT PLAN (As Amended And Restated Effective As Of April 1, 1995) 128 CENTRAL ILLINOIS PUBLIC SERVICE COMPANY SPECIAL EXECUTIVE RETIREMENT PLAN (As Amended And Restated Effective As Of April 1, 1995) The Central Illinois Public Service Company Special Executive Retirement Plan (the "Plan") was established by Central Illinois Public Service Company (the "Company") effective as of February 3, 1987, for eligible participants. The terms and conditions of the Plan, as amended and restated effective as of April 1, 1995, are hereinafter set forth. The Plan is not a qualified plan for purposes of Section 401(a) of the Internal Revenue Code of 1986, as amended (the "Code"). The purpose of the Plan is to provide retirement benefit payments to eligible participants, as defined in Article I, in addition to the payments provided under the Central Illinois Public Service Company Retirement Income Plan ("Retirement Income Plan"). For purposes of the Plan, the term "Employer" shall mean the Company and any affiliated employer to which the Plan is extended by the Board of Directors of the Company (the "Board of Directors") and which adopts the Plan. ARTICLE I. Eligible Participants 129 An "eligible participant" shall mean an employee of an Employer who was hired from outside the Employer, including from outside any affiliate of the Employer, as a senior officer of the Employer and who is a participant in and qualifies for a benefit under the Retirement Income Plan at his Termination Date. For this purpose, a senior officer shall include the President, a Vice-President and such other officer of an Employer as shall be designated from time to time by the Board of Directors of the Employer, and Termination Date shall mean the date an employee terminates his employment with the Employers and affiliates of the Employers due to death, disability, retirement at or after his Normal Retirement Date as defined in the Retirement Income Plan, retirement prior to his Normal Retirement Date with the consent of the Board of Directors of the Employer, or termination for any reason within the two year period beginning on the date of the occurrence of a Change in Control (as defined in paragraph 4(c) of Article III.B). ARTICLE II. Supplemental Benefits Subject to the provisions of Article III hereof, an eligible participant shall be entitled to receive a monthly benefit under the Plan in the amount of the excess of (a) over (b), where (a) equals the amount of monthly benefit which would have been paid or payable to such eligible participant under the Retirement Income Plan if retirement benefit payments under the Retirement Income Plan were computed (i) without regard to the 130 limitations imposed by Sections 401(a)(17) and 415 of the Code and (ii) as though Credited Service, as defined in the Retirement Income Plan, has been accrued as hereinafter provided, and (b) equals the sum of (i) the amount of monthly benefit that is paid or payable to such eligible participant under the Retirement Income Plan, (ii) the amount of monthly benefit paid or payable from any other defined benefit pension plan as a result of the eligible participant's prior employment with any employer which is not an Employer as defined in the Retirement Income Plan, (iii) the amount of monthly benefit paid or payable under the Central Illinois Public Service Company Excess Benefit Plan, and (iv) the amount of monthly benefit paid or payable after his Termination Date under any employment contract between the eligible participant and an Employer (specifically, excluding, however, any amount paid or payable under any Management Continuity Agreement" that becomes operative only on a change in control). The amount of monthly benefit under (b)(ii), (iii) or (iv) shall be an amount determined by the Committee, applying uniform standards, which shall be equal to the amount of monthly benefit which would be yielded by the present value of the expected payments to be made and/or which have been made under such other plans or contracts over the projected period of payment of benefit, and in the projected form of benefit, under the Retirement Income Plan. For purposes of this paragraph, any benefit referred to in (a) or (b) shall be determined without regard to the provisions of any applicable "qualified domestic relations order" as defined in 131 Section 414(p) of the Code. For purposes of the preceding paragraph, Credited Service means 35 years of Credited Service, provided, however, that if the eligible participant terminates his employment with the Company and its affiliates for any reason, including retirement or death, prior to his Normal Retirement Date as defined in the Retirement Income Plan, such Credited Service shall be the number of years of Credited Service obtained by multiplying 35 by a fraction, the numerator of which is the eligible participant's number of years of Credited Service computed under the Retirement Income Plan without regard to the provisions of this Plan and the denominator of which is the number of years of Credited Service the eligible participant would have had under the Retirement Income Plan had he continued in full-time employment with the Company and its affiliates until his Normal Retirement Date. Upon the death of the eligible participant, a monthly benefit shall be paid under the Plan to his Eligible Spouse, as defined under the applicable provisions of the Retirement Income Plan; provided, however, that such Eligible Spouse is married to the eligible participant on his date of death. The monthly benefit payable under the Plan to the Eligible Spouse shall be a percentage of the benefit provided under the Plan for the eligible participant. The percentage shall be determined in accordance with the provisions of the Retirement Income Plan for computing the benefit of an Eligible Spouse. 132 ARTICLE III. General Provisions A. Reference to the Retirement Income Plan - The Retirement Income Plan, whenever referred to in the Plan, shall mean the Retirement Income Plan as in effect on the eligible participant's Termination Date or other date of determination.

Payments under this paragraph 4 to or in respect of an eligible participant or Eligible Spouse shall be made within [30] days after the date on which the Change in Control occurs or, if later, the date the eligible participant terminates employment with the Company and its affiliates. In the event an individual entitled to payment under this paragraph 4 dies after the later of such dates but prior to payment, the payments under this paragraph 4 shall be made to the individuals surviving spouse, if any, or to the executor or administrator of the individuals estate in the event the individual does not have a surviving spouse. (b) The amount of lump sum payment and additional payment under this paragraph 4 shall be determined by the Committee using, in the case of the lump sum payment, the applicable mortality table and the applicable interest rate provided under Section 417(e)(3)(A) of the Code, or any successor provision thereto, and the regulations, rulings and announcements issued thereunder.

G. Facility of Payment - Whenever and as often as any person entitled to payments under the Plan shall be under a legal disability or, in the sole judgment of the Committee, shall otherwise be unable to apply such payments to his own best interest and advantage, the Committee, in the exercise of its discretion, may direct all or any portion of such payments to 142 be made in any one or more of the following ways: (i) directly to him; (ii) to his legal guardian or conservator; or (iii) to his spouse or to any other person, to be expended for his benefit; and the decision of the Committee shall in each case be final and binding upon all persons in interest. H. No Guarantee of Employment - Nothing contained in the Plan shall be construed as a contract of employment between the Company or its affiliates and any employee, or as a right of any employee, to be continued in the employment of the Company or its affiliates, or as a limitation of the right of the Company or its affiliates to discharge any of its employees, with or without cause. I. Participants' Interests Not Transferable - Prior to payment, the interests of eligible participants and their Eligible Spouses under the Plan are not in any way subject to their debts or other obligations and may not be voluntarily or involuntarily sold, transferred, alienated, assigned or encumbered.

This Plan shall be binding upon and inure to the benefit of the Employer and any successor of or to the Employer, including without limitation any persons acquiring directly or indirectly all or substantially all of the business and/or assets of the Employer whether by sale, merger, consolidation, reorganization or otherwise (and any such successor to the Company shall thereafter be deemed the "Company" for the purposes of this Plan) and the heirs, executors and administrators of each participant. M. Vested Benefit - Each employee of an Employer on December 31, 1993 who is eligible to take normal or early retirement under the Retirement Income Plan and who on such retirement would be an eligible participant as defined in Article I shall be fully vested in his Accrued Benefit under the Plan as of December 31, 1993 subject to the terms and conditions of the Plan. For this purpose, "Accrued Benefit" means the amount of monthly benefit to which such employee would be entitled under Article II of the Plan if he terminated his employment 144 with the Company and its affiliates as of December 31, 1993. Such employee's Accrued Benefit shall also include the amount of monthly benefit to which the employee's Eligible Spouse would be entitled following his death.
