II. PURPOSE The purpose of the Plan is to enable the Company and its subsidiaries to attract, retain, and motivate executives of outstanding competence by providing, among other benefits, the opportunity to defer a portion of their Total Cash Compensation. The Plan permits each Participant to custom design his or her individual level of retirement income. III. CONSTRUCTION Section 3.1. Definitions.

(c) "Change in Control" means either: (i) Approval by the shareholders of the Company of a plan of merger, consolidation, or reorgani- zation of the Company unless at least sixty percent (60%) of the members of the board of directors of the corporation resulting from such merger, consolidation, or reorganization were members of the Incumbent Board; or (ii) The occurrence of any other event that is designated as being a "Change in Control" by a majority vote of the directors of the Incumbent Board, who are not also employees of Iowa-Illinois Gas and Electric Company. (d) "Change-in-Control Benefit" means, with respect to each Participant, his or her Early Retirement Benefit, computed as of the effective date of his or her Qualifying Termination as though such Participant were age fifty-five (55) at such time, or his or her actual age if greater.

Such Disability shall be determined by the Committee in the exercise of good faith and reasonable judgment in reliance on competent medical advice from one or more qualified individuals selected by the Committee.

(ii) For deferrals made by a Participant after December 31, 1993, his or her Normal Retirement Benefit reduced by a cumulative percentage, based upon his or her actual age on the effective date of Termination of Services with the Company, as follows: Age of Participant Percentage Reduction Upon Termination for Each Year Prior to of Services Normal Retirement Age 65 65 or more 0% 62 to less than 65 4% 50 to less than 62 6% This reduction is cumulative such that a Termination of Services at age fifty-five (55) would result in a fifty-four percent (54%) reduction in the Normal Retirement Benefit [i.e., three (3) years at four percent (4%), plus seven (7) years at six percent (6%)]. (l) "Early Retirement" means, with respect to each Participant, the effective date of Termination of Services of such Participant other than because of death, Disability, Cause, or Qualifying Termination after such Participant has attained age fifty (50) for deferrals made after December 31, 1993, and age fifty-five (55) for deferrals made prior to January 1, 1994, but in all cases prior to such Participant's Normal Retirement Date.

Table I attached to this document, entitled "Iowa- Illinois Revised Benefit Table," specifies the Rate of Return for Deferred Compensation in the Plan Year beginning January 1, 1991, and each Plan Year thereafter until such Rate of Return is revised by action of the Committee. (aa) "Survivor's Benefit" means the benefit payable to a Participant's designated beneficiary or estate under the Plan, as specified in Section 7.5(a), in the event of such Participant's death prior to the commencement of the payment of any benefit hereunder.

Section 3.3. Severability. In the event any provision of the Plan shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining provisions of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included. IV. ADMINISTRATION Section 4.1. The Committee. The Plan shall be administered within the guidelines contained in this Article IV by an Administrative Committee comprised of Company employees selected by the President of the Company and approved by the Board. The Committee may delegate the responsibility of performing ministerial acts to such administrative agents as it shall deem advisable or desirable to carry out the purpose of the Plan. Section 4.2. Authority of the Committee. Subject to ratification by the Board, the Committee shall have the power to construe and interpret the Plan and any agreement or instrument entered into hereunder; to prescribe, amend, or waive rules and regulations for the Plan's administration; and to make any other determination which may be necessary or advisable for the Plan's administration. The Committee may correct any defect or supply any omission or reconcile any inconsistency in the Plan in the manner and to the extent reasonable to effect its purpose. The manner of investment of Deferred Compensation hereunder shall be in the sole discretion of the Committee. The Company may elect to insure the lives of Participants, in which case Participants must agree to undergo physical examinations and otherwise cooperate in obtaining such insurance as a condition precedent to participation in the Plan. Any such life insurance policies shall be owned by and considered a general asset of the Company. Subject to Section 8.2, no Participant or designated beneficiary shall have any rights to or interest in or shall be entitled to any benefits under such policies. Section 4.3. Decisions Binding. All determinations and decisions made by the Committee pursuant to the provisions of the Plan, as ratified by the Board, and all related orders or resolutions of the Board, shall be final, conclusive, and binding on all persons, including the Company, its shareholders, employees, the Participants and their estates and designated beneficiaries. The Board shall have the full power to amend or terminate the Plan at any time prior to the occurrence of a Change in Control. V. ELIGIBILITY AND PARTICIPATION Section 5.1. Eligibility. All Designated Officers shall be eligible to participate in the Plan. Section 5.2. Participation. Upon approval by the Board, Eligible Employees shall be notified of their ability to elect to make deferrals under the Plan. Upon receiving notification of eligibility, and at the beginning of each Plan Year thereafter, each Eligible Employee desiring to become a Participant under the Plan must complete and return to the Company a Participation Agreement, as described in section 6.2, before any deferrals can be made under the Plan. Retired individuals who have a vested accrued benefit under the Plan will also be considered to be Participants. Section 5.3. No Employment Guarantee. Neither the existence of the Plan nor any action taken hereunder shall be construed as giving a Participant the right to be retained as an employee of the Company for any period. VI. DEFERRAL OPPORTUNITY Section 6.1. Amount Which May Be Deferred. For the 1992 and 1993 Plan Years, each Participant may defer twenty five percent (25%) of his or her Total Cash Compensation. For each Plan Year beginning thereafter, each Participant may defer a maximum of fifteen percent (15%) of his or her Total Cash Compensation. The Committee may establish, from time to time, a minimum level of Total Cash Compensation which may be deferred hereunder in any Plan Year. Section 6.2. Participation Agreement. Each Eligible Employee shall identify the amount of Deferred Compensation in any Plan Year by the execution of a Participation Agreement prior to the beginning of such Plan Year. A Participation Agreement shall be sent to each Eligible Employee by the Committee at least fifteen (15) calendar days prior to the beginning of each Plan Year. The amount of Deferred Compensation shall reduce the Total Cash Compensation otherwise payable to such Eligible Employee during such Plan Year by ratably deducting an equal amount from the Participant's salary for each pay period. Such Participation Agreement shall remain in effect for the entire Plan Year unless earlier amended or modified pursuant to Section 6.3. Section 6.3. Modification of Deferral During Plan Year. The Committee, in its sole discretion, may permit prospective modifications to a Participation Agreement for the remainder of a Plan Year, but only for the purpose of decreasing or terminating the amount to be deferred. A request to decrease or terminate the amount to be deferred under a Participation Agreement shall be submitted by a Participation agreement shall be submitted by a Participant in writing to the Committee and shall set forth in detail the reasons for the requested modification. If a modification shall be granted by the Committee, such modification shall be effective for the balance of the Plan Year to which such Participation Agreement relates. VII. BENEFITS Section 7.1. Benefits Upon Normal Retirement.

Section 7.4. Benefits Upon a Qualifying Termination. After a Participant's Qualifying Termination, the Company shall pay to the Participant, as compensation for services rendered prior to such date, his or her Change-in-Control Benefit, payable in equal monthly installments commencing on the later of: (i) the first day of the month next following the effective date of the Qualifying Termination; or (ii) the first day of the month next following the date that the Participant achieves age fifty-five (55); and in all cases, continuing on the first day of each month thereafter during the lifetime of the Participant. Section 7.5. Benefits Upon Death. Upon a Participant's death, the Company shall pay to such Participant's designated beneficiary or estate, as appropriate, the following benefit: (a) Death Prior to Commencement of Benefits. If a Participant dies prior to commencement of the payment of any benefit hereunder, the Company shall pay to such Participant's designated beneficiary or estate the Survivor's Benefit in one hundred eighty (180) equal monthly installments commencing on the first day of the month following such date of death and receipt of a death certificate by the Company and continuing on the first day of each month thereafter until one hundred eighty (180) payments have been made.

Following a Participant's death, in the event the Participant's beneficiary dies before receiving the remainder of the one hundred eighty (180) of the above described Normal Retirement Benefit, Early Retirement Benefit, Disability Benefit or Change- in-Control Benefit payments, the then remaining payments shall be paid to the beneficiary's estate in equal monthly installments until the one hundred eighty (180) payments have been made or, in the event the beneficiary is a spouse, to the beneficiary of the spouse as elected pursuant to the beneficiary election form. (c) Payment by the Company of the benefit in Section 7.5(a) or (b) shall relieve the Company of the obligation to pay a Normal Retirement Benefit, an Early Retirement Benefit, a Disability Benefit, or a Change-in-Control Benefit or any other benefit which the Participant might have otherwise received under the Plan. Section 7.6. Benefits Upon Termination for Cause.

All assets held in the Rabbi Trust (while revocable or irrevocable) shall at all times be specifically subject to the claims of the Company's general creditors in the event of bankruptcy or insolvency; such terms shall be specifically defined within the provisions of the Rabbi Trust, along with a required procedure for notifying the Trustee of any such bankruptcy or insolvency.

Section 8.3. Payment of Benefits from the Trust. The Company shall be primarily obligated to pay all benefits of Participants under the Plan, whether the Rabbi Trust is revocable or irrevocable at the time. In the event the Company fails to fulfill any such obligation hereunder in a timely manner, the Trustee shall be empowered, under the terms of the Rabbi Trust, to either cash in the related life insurance policies or to borrow against the policies, to the extent necessary to pay past due benefits directly from the Trust. IX. BENEFICIARY DESIGNATION Section 9.1. Designation of Beneficiary. Each Participant shall be entitled to designate one or more beneficiaries by filing a signed, written notice of such designation with the Committee, in a form as the Committee may prescribe. A Participant may revoke or modify a beneficiary designation at any time by filing a new beneficiary designation form with the Committee. Section 9.2. Payment to a Participant's Estate. A Participant's beneficiary designation shall be deemed automatically revoked in the event all designated beneficiaries predecease such Participant or, if the sole beneficiary is such Participant's spouse, in the event of dissolution of marriage. In such event, or in the event a Participant does not designate a beneficiary, the benefits under Section 7.5 shall be paid to such Participant's estate. X. MISCELLANEOUS Section 10.1. Unfunded Plan. This Plan is intended to be an unfunded plan maintained primarily to provide benefits to a "select group of management or highly compensated employees" within the meaning of Sections 201, 301, and 401 of ERISA and, therefore, is further intended to be exempt from the provisions of Parts 2, 3, and 4 of Title I of ERISA. Accordingly, the Committee may terminate the Plan for any or all Participants in order to achieve and maintain this intended result, provided that previously accrued benefits hereunder shall not be reduced or otherwise adversely affected without the written consent of all affected Participants. Section 10.2. Withholding. The Company shall have the right to require Participants to remit to the Company an amount sufficient to satisfy Federal, state, and local tax withholding tax requirements, or to deduct from any or all payments made pursuant to the Plan amounts sufficient to satisfy such withholding tax requirements. Section 10.3. Costs of the Plan. All costs of implementing and administering the Plan shall be borne by the Company. Section 10.4. Nontransferability. Neither the Participants nor any designated beneficiary shall have the right to sell, assign, transfer, or otherwise convey the right to receive any payment hereunder; nor shall any such payment be subject to attachment, garnishment, levy, pledge, bankruptcy, or any other manner or kind of execution in connection with any claim against the Participants or any designated beneficiary thereof. Section 10.5. Successors. All obligations of the Company under the Plan shall be binding upon and inure to the benefit of any successor to the Company, whether the existence of such successor is the direct or indirect result of a merger, consolidation, or reorganization involving the Company or the purchase or other acquisition of all or substantially all of the business and/or assets of the Company. Section 10.6. Address of Participant or Beneficiary. Each Participant shall keep the Company apprised of his or her current address and that of any designated beneficiary during his or her participation in the Plan. Upon the death of a Participant, any beneficiaries entitled to receive benefit payment under the Plan shall keep the Company apprised of their current address until the entire amount to be distributed has been paid. Section 10.7. Applicable Law. To the extent not preempted by Federal law, the Plan shall be governed by and construed in accordance with the laws of the State of Illinois.
