1 EXHIBIT 10.66 MANAGEMENT SUPPLEMENTAL BENEFIT PLAN --------------------------------------------------------------- 2 SECOND RESTATEMENT OF THE DETROIT EDISON COMPANY MANAGEMENT SUPPLEMENTAL BENEFIT PLAN The Detroit Edison Company Management Supplemental Benefit Plan (the "Plan"), established by The Detroit Edison Company (the "Company") effective July 24, 1989, as amended and restated effective January 22, 1990, is hereby amended and restated as of June 26, 1995, by this Second Restatement. PURPOSE The Management Supplemental Benefit Plan ("Plan") is designed to supplement pension benefits for eligible management employes. The Plan has the objective of making the Company's retirement program more competitive within the electric utility industry and general industry, which will facilitate the attraction and retention of management employes. DEFINITION AVERAGE FINAL COMPENSATION. Equals one-fifth of normal pay during the 260 weeks of Company service that results in the highest average, calculated without regard to any limitation imposed by Section 401(a)(17) of the Internal Revenue Code. AWARDED SERVICE. Years of service that may be imputed to an otherwise eligible Plan participant by the Organization and Compensation Committee ("Committee") of the Board of Directors, having taken into account the value to the Company of such participant's prior experience. COMPANY SERVICE. All years of service with the Company calculated to the nearest month. EXECUTIVE POST-EMPLOYMENT INCOME ARRANGEMENT. Individual arrangements that were entered into with certain executives upon initial employment with the Company. The arrangements may provide for additional benefits upon retirement. KEY EMPLOYE DEFERRED COMPENSATION PLAN. The Key Employe Deferred Compensation Plan initiated in 1964 which provides a supplemental pension benefit to certain management employes. NORMAL PAY. The employe's salary for a standard forty-hour work week calculated without regard to any limitation imposed by Section 401(a)(17) of the Internal Revenue Code 1 3 including amounts deferred by the employe under the Company's qualified and non-qualified savings plans. It does not include any bonuses, special pay, or premium for overtime work. RETIREMENT PLAN. The Employes' Retirement Plan of The Detroit Edison Company ("Detroit Edison"). The Retirement Plan is a defined benefit pension plan sponsored by Detroit Edison for eligible employes. RETIREMENT ALLOWANCE FACTOR. The multiplier used in the basic formula of the Retirement Plan. ELIGIBILITY Eligibility to participate in this Plan is determined no later than the latest to occur of: (1) 90 days from the date hereof; or (2) 90 days subsequent to an otherwise eligible participant's 55th birthday; or (3) In the case of an otherwise eligible participant who does not have at least 10 years of Company service at age 55, 90 days subsequent to the otherwise eligible participant's having 10 years of Company service. Participation in the Plan is limited to those management employes who (1) Are members of Management Council (pursuant to OR3, Management Groups, as may be amended from time to time) at the time of termination from the Company (or death while actively employed by the Company); and (2) Are not personally eligible to receive a benefit from the Key Employe Deferred Compensation (KEDC) Plan although a court of competent jurisdiction may have recognized spousal rights; (3) Do not have an effective Executive Post-Employment Income Arrangement; and (4) At the time of termination from the Company (or death while actively employed), are at least 55 years of age and have at least 10 years of Company service. Employes who are eligible to receive a benefit from KEDC or who have entered into Post-Employment Income Arrangements with the Company may elect to participate in this Plan in accordance with the first paragraph of this section by filing an election to waive any rights to 2 4 a benefit from KEDC and/or any rights under a Post-Employment Income Arrangement with the Vice President-Human Resources, who will provide an election form upon request. TARGET PERCENTAGE OF AVERAGE FINAL COMPENSATION Payments from the Plan are based upon the calculated target percentage of average final compensation. The target percentage of average final compensation is determined by years of Company service and awarded service, if any, and by the management group in which the participant is a member at the time of termination from the Company (or death while actively employed by the Company) as specified in Exhibit A. Participants awarded service under the Plan must certify any retirement income expected or being received from a previous employer. Payments from the Plan to participants with awarded service will be reduced by the non-contributory portion of any retirement income expected or being received from a previous employer. Payments from the Plan will be reduced by any KEDC spousal payments required by a court of competent jurisdiction. Payments from the Plan may also be affected by the employe's age at termination (see Early Retirement) and the payment option selected by the employe (see Payment Options). EARLY RETIREMENT The Plan provides for an unreduced target percentage for those terminating employment at age 60 or older. A reduced or adjusted target percentage is provided for those terminating employment (including death) who are at least age 55 but prior to age 60. The early retirement adjustment schedule is as follows: AGE AT EARLY RETIREMENT TERMINATION ADJUSTMENT PERCENTAGE 55 50% 56 60% 57 70% 58 80% 59 90% 60 or older 100% Age at termination is calculated to the nearest whole month and the early retirement adjustment percentage is determined accordingly. 3 5 PAYMENT OPTIONS At the time of employment termination, an eligible employe must elect one of the following payment options: (a) Guaranteed Term Plus Life, (b) Actuarial-Adjusted Life with a 100% Joint and Survivor Benefit and (c) Actuarial-Adjusted Life with a 50% Joint and Survivor Benefit. In the event that an employe dies during active employment, and at the time of death was eligible for a benefit as provided herein, the payment option is deemed to be Guaranteed Term Plus Life. GUARANTEED TERM PLUS LIFE If the employe elects the Guaranteed Term Plus Life payment option, the employe, at the time of employment termination, must also elect a survivor benefit of either monthly payments or an adjusted lump sum payment. In the event that such an election is not made by the employe, or in the event that the employe dies during active employment and at the time of death was eligible for a Plan benefit as provided herein, the survivor benefit is assumed to be the adjusted lump sum payment. The Guaranteed Term Plus Life payment option provides for a minimum of 15 years of payments to the employe or, if the employe lives beyond the 15-year period, the payments continue to be made to the employe for the life of the employe. If the employe elects the monthly payment survivor benefit and dies prior to the end of the 15-year period, payments will continue to be made to the employe's beneficiary or estate for the balance of the 15-year period. At the end of this 15-year period, all payments cease and liability of the Company under the Plan is terminated. If the employe elects the lump sum payment survivor benefit and dies prior to the end of the 15-year period, an adjusted lump sum payment is made to the employe's designated beneficiary or estate. The adjusted lump sum payment is determined by a standard annuity calculation where the adjusted lump sum is the present worth of the remaining monthly benefits in the 15-year period. The methodology and other relevant factors for determining the amount of the adjusted lump sum payment are provided in Exhibit B. Upon payment of the lump sum payment, all payments cease and liability of the Company under the Plan is terminated. ACTUARIAL-ADJUSTED LIFE WITH A 100% JOINT AND SURVIVOR BENEFIT This option provides for the actuarial equivalent to the benefit payment under the Guaranteed Term Plus Life option. Upon the death of the employe and the designated beneficiary, all 4 6 payments cease and the liability of the Company under the Plan is terminated. The actuarial equivalent benefit is provided for the life of the employe and upon the death of the employe, 100% of the benefit is provided to the employe's designated beneficiary for the duration of the beneficiary's life. If the employe's designated beneficiary should die prior to the employe, payments continue from the life of the employe and upon the death of the employe all payments cease and liability of the Company under the Plan is terminated. If the employe and designated beneficiary are the same age, the actuarial equivalent benefit equals 97.94% of the Guaranteed Term Plus Life benefit. If the beneficiary is younger than the employe, this percentage is reduced by 1.2% for each 12 full months of difference in age. If the beneficiary is older than the employe, this percentage is increased 1.2% for each 12 full months in difference in age up to a maximum of 100%. ACTUARIAL-ADJUSTED LIFE WITH A 50% JOINT AND SURVIVOR BENEFIT This option provides for the actuarial equivalent to the benefit payable under the Guaranteed Term Plus Life option. Upon the death of the employe and the designated beneficiary, all payments cease and the liability of the Company under the Plan is terminated. The actuarial equivalent benefit is provided for the life of the employe and upon the death of the employe, 50% of the benefit is provided to the employe's designated beneficiary for the duration of the beneficiary's life. If the employe's designated beneficiary should die prior to the employe, payments continue for the life of the employe and upon the death of the employe all payments cease and liability of the Company under the Plan is terminated. If the employe and designated beneficiary are the same age, the actuarial equivalent benefit equals 107.72% of the Guaranteed Term Plus Life benefit. If the beneficiary is younger than the employe, this percentage is reduced by 1% for each 12 full months of difference in age. If the beneficiary is older than the employe, there is no adjustment to the percentage. If the employe does not designate a beneficiary, the actuarial equivalent benefit equals 107.72% of the Guaranteed Term Plus Life benefit, and upon the death of the employe all payments cease and the liability of the Company under the Plan is terminated. PAYMENT CALCULATION Monthly payments from the Plan are determined as follows: STEP 1. DETERMINE GROSS TARGET AMOUNT The gross target amount results from multiplying the target percentage by average final compensation (see Exhibit A to determine the target percentage). 5 7 STEP 2. DETERMINE RETIREMENT PLAN BENEFIT The Retirement Plan benefit results from multiplying the retirement allowance factor by average final compensation and by Company service, calculated for purposes hereof, without regard to any limitations imposed by Section 401(a)(17) or Section 415 of the Internal Revenue Code. STEP 3. DETERMINE BASE ANNUAL TARGET BENEFIT AMOUNT The base annual target benefit amount results from subtracting the Retirement Plan benefit from the gross target amount. STEP 4. DETERMINE ADJUSTED ANNUAL TARGET BENEFIT AMOUNT The adjusted annual target benefit amount results from multiplying the base annual target benefit amount by the early retirement adjustment percentage (see page 4 to determine the early retirement adjustment percentage). STEP 5. DETERMINE MONTHLY TARGET BENEFIT AMOUNT UNDER THE GUARANTEED TERM PLUS LIFE PAYMENT OPTION The monthly target benefit amount under the Guaranteed Term Plus Life payment option is determined by dividing the adjusted annual target benefit amount by 12. STEP 6. ACTUARIAL-ADJUSTED PAYMENT OPTION If an actuarial-adjusted payment option is selected, the actuarial adjustment is applied to the monthly target benefit amount under the Guaranteed Term Plus Life payment option. Exhibit C displays examples of the Plan payment calculation procedure. In the event an employe receives an assessment of income taxes from the Internal Revenue Service which treats any amount under this Plan as includible in such employe's gross income prior to payment of such amount to such employe, the Company shall pay an amount equal to such income taxes to such employe within 30 days after receipt of written notice from such employe about such assessment. The base annual target benefit amount (Step 3) shall be reduced by an amount equal to such income taxes and Steps 4, 5 and 6 shall be reduced accordingly. Each payment under this Plan shall be reduced by any federal, state or local taxes which the Company determines should be withheld from such payment. 6 8 SCHEDULE OF PAYMENTS Plan payments, if any, are made to the employe or to the designated beneficiary on a monthly basis. The schedule will follow the provisions for payment under the Retirement Plan. The accompanying examples show the effect of Retirement Plan benefits at different times. BENEFICIARY DESIGNATION Each eligible participant may name any beneficiary to whom payments under the Plan are to be paid in case of the employe's death. Each designation will revoke all prior designations by the employe and shall be on a form prescribed by the Company and will be effective only when filed by the employe with the Treasurer. In the absence of any such designation, payments due shall be paid to the employe's estate. TAXATION The Company makes no representation as to the tax consequences of individual payment options. Plan participants are urged to consult tax advisors of their choice for information and advice. NON-SECURED PROMISE; AMENDMENTS Eligible participants have the status of general unsecured creditors of the Company. This Plan constitutes a promise by the Company to make benefit payments in the future. The Company intends that this Plan be unfunded for tax purposes and for purposes of Title I of ERISA. The Company intends that this Plan be maintained primarily for a select group of management or highly compensated employes. Payments under this Plan as they become due shall be paid by the Company from its general assets. The Company reserves the right to amend, modify, or discontinue this Plan at any time; provided, however, that no such amendment, modification, or termination shall affect the rights of participants or beneficiaries who are receiving or are immediately eligible to receive benefits from this Plan at the time of such amendment, modification, or termination. 7 9 ADMINISTRATION; ARBITRATION The Vice President-Human Resources is responsible for the administration of the Plan. The Vice President-Human Resources has the authority to interpret the provisions of the Plan and prescribe any regulations relating to its administration.

The place of the arbitration shall be the offices of the American Arbitration Association in the Detroit Metropolitan area, Michigan. The arbitrator(s) shall not have the jurisdiction or authority to change any of the provisions of this Plan by alteration of, addition to, or subtraction from the terms thereof. The arbitrator(s)' sole authority shall be to apply any terms and conditions of this Plan. Since arbitration is the exclusive remedy with respect to any Grievance, no employe eligible to receive benefits under this Plan has the right to resort to any federal court, state court, local court, or administrative agency concerning breaches of any terms and provisions hereunder, and the decision of the arbitrator(s) shall be a complete defense to any suit, action, or proceeding instituted in any federal court, state court, local court, or administrative agency by such employe or the Company with respect to any Grievance which is arbitrable as herein set forth. The arbitration provisions shall, with respect to any Grievance, survive the termination of this Plan. 8 10 NON-ALIENABILITY AND NON-TRANSFERABILITY The right of a participant, participant's spouse or beneficiary to payment of any benefit hereunder shall not be alienated, assigned, transferred, pledged or encumbered and shall not be subject to execution, attachment or similar process.
