The rights of employees who, prior to May 1, 1998, retired, died or whose services were terminated are governed by the provisions of the instrument in effect at such time.

In the case of the transfer to this Company of any participant employed by any company now affiliated or associated with the Company which has at the time of transfer a pension plan with substantially the same terms as the Pension Plan, and a supplemental plan with substantially the same terms as this Supplemental Plan, such Participant, if and when he commences to receive Retirement Income under the Pension Plan, will also receive Supplemental Executive Retirement Income from the Company based upon the earnings and executive incentive compensation received from the company from which he transferred as if such earnings and executive incentive compensation were Earnings and Executive Incentive Compensation received from the Company.

SECTION V. SUPPLEMENTAL EXECUTIVE RETIREMENT INCOME While the Company hopes and expects to continue the Supplemental Plan indefinitely, it reserves the right to terminate or modify it at any time. 1. NORMAL OR DEFERRED SUPPLEMENTAL EXECUTIVE RETIREMENT INCOME. The monthly Supplemental Executive Retirement Income payable to a Participant who, at Normal Retirement Date or a Deferred Retirement Date, retires on or after September 1, 1995, pursuant to the provisions of the Pension Plan from the service of the Company, will be an amount equal to the product of the Participant's Final Executive Pay times the sum of the percentages determined below, plus, for each employee who retires with 35 years of Accredited Service under the Pension Plan, an amount equal to $20.00 for each additional full year of vested service that would otherwise have been credited as Accredited Service but for the application of the minimum age requirements in the Pension Plan or the 35-year Accredited Service maximum, minus (i) a portion of the Participant's estimated primary Social Security benefit, as determined pursuant to the Pension Plan, equal to the lesser of (1) .5% multiplied by 1/12th of the Participant's "Final Average Compensation" up to "Covered Compensation" (as those terms are used in Section 401(l) of the Internal Revenue Code) for each year of Accredited Service and Preference Service, (2) 1/2 of the benefit that would be provided prior to the application of the offset, with respect to Participant's Final Pay up to Covered Compensation, or (3) the maximum offset allowed under Section 401(l) of the Internal Revenue Code, and (ii) the Retirement Income provided by the Pension Plan: 2.1% for each of the first 20 years of Accredited Service and Preference Service. 1.5% for each of the next 15 years of Accredited Service and Preference Service. 2. EARLY SUPPLEMENTAL EXECUTIVE RETIREMENT INCOME. The monthly Supplemental Executive Retirement Income payable to a Participant who, on an Early Retirement Date, retires from the service of the Company, will be the amount of his Accrued Supplemental Executive Retirement Income on the date his retirement commences, reduced by 5/12th of 1% for each month by which his Early Retirement Date precedes his Normal Retirement Date by more than 36 months. 3. LIMITATION AS TO MONTHS FOR WHICH PAYMENT MAY BE MADE. The Company shall pay to a Participant, or to his Provisional Payee, if applicable, Supplemental Executive Retirement Income in the amount determined pursuant to this Supplemental Plan only for a month in which the Participant or his Provisional Payee is entitled to receive Retirement Income under the provisions of the Pension Plan or would be entitled to Retirement Income but for the election of a Single Sum payment under the Pension Plan. Payment of Supplemental Executive Retirement Income shall terminate when payment of Retirement Income is terminated pursuant to the Pension Plan. 4. The payments provided for in this Supplemental Plan shall be made by the Company at such times as required under this Supplemental Plan; provided, however, that, while the Company hopes and expects to make the payments provided for under this Supplemental Plan, such payment is not guaranteed. 5. The Company may establish a fund, as part of the general assets of the Company, to provide for the payments required under this Supplemental Plan. 4 5 6. MAXIMUM PERMISSIBLE RETIREMENT INCOME. Notwithstanding any other provision of this Supplemental Plan, if the Retirement Income payable to a retired employee under provisions of subsection 7 of Section V of the Pension Plan is a greater amount than permitted by Section 415 of the Internal Revenue Code to be paid by qualified plans, then such excess Retirement Income shall be payable to such retired employee under this Plan; subject, however, to approval by the Board of Directors of the Company for each such employee. 7. SINGLE SUM PAYMENT. The Retirement Board, after discussion with a retiring Participant, may pay in a single sum to such Participant, who retires on or after February 1, 1991, at the time of the Participant's retirement with benefits under the Pension Plan, the present value of the Participant's Supplemental Executive Retirement Income. The present value of that part of the Participant's Supplemental Executive Retirement Income which represents payment to make up Retirement Income lost under the Pension Plan because of the Maximum Retirement Income provision thereof (Section V, subsection 6 of the Plan) will not be paid in a lump sum unless the Participant has elected to receive a single sum payment under the Pension Plan. The present value will be actuarially determined using the Pension Benefit Guaranty Corporation Immediate Annuity Rate, as of the date of the distribution, increased to 120%. The discussion with a retiring Participant is for the purpose of assuring the Retirement Board of accurate current information for use in making its independent decision as to whether or not to make payment in a single sum. In making its independent decision, the Retirement Board may take into account any financial hardship of the Participant, the health or disability of the Participant, and/or any other factor it considers relevant. The decision of the Retirement Board shall be in the sole discretion of said Board and shall be final, binding and conclusive. Discussion with respect to such a payment and the decision with respect thereto will take place at least three months before Early Retirement Date, Normal Retirement Date or Deferred Retirement Date. The SERP Retirement Board will not render a decision regarding a single sum payment any earlier than six months prior to the Participant's actual retirement date. 8. RETIRED PARTICIPANTS. The Supplemental Executive Retirement Income of retired Participants may be increased from time to time by such reasonable amounts as determined by the Board of Directors of the Company, to counter the effects of inflation, provided that the percentage amount of such increases will be made uniformly for all retired Participants, or for retired Participants within such reasonable classes, as may be determined by the Board of Directors. This provision shall not apply to any Participant who has received his benefit as a single sum. 9. DISABILITY SERVICE PENSION SUPPLEMENT. If a Participant is totally disabled (unable to perform the Participant's regular job because of disease or injury) and, as a result, fails to accumulate Accredited Service under the Pension Plan for some period of time (Disability Service), a Disability Service Pension Supplement will be calculated and paid as if Accredited Service and applicable Preference Service were credited during such period subject to the following: A. The Participant must have retired with Retirement Income under the Pension Plan. B. The period of Disability Service begins when the Participant stops accumulating Accredited Service under the Pension Plan as a result of the Participant's total disability, provided that the Participant has not undertaken other employment. C. The period of Disability Service ends when the Participant first: 1. Begins again to accumulate Accredited Service under the Pension Plan, 2. Undertakes other employment, 3. Retires on an Early Retirement Date, or, 5 6 4. Attains the Participant's Normal Retirement Date. D. The "Final Executive Pay" of the Participant, for purposes of determining the Disability Pension Supplement only, will be calculated as if the Participant were earning during the period of Disability Service the sum of (1) the Participant's last monthly rate of basic earnings prior to the period of Disability Service, and (2) 1/12th of the average of the Executive Incentive Compensation (if any) for the five years of Accredited Service while in an eligible salary grade immediately preceding the period of Disability Service (or the monthly average of Executive Incentive Compensation earned over the Participant's Accredited Service if the Participant has fewer than five years of Accredited Service while in an eligible salary grade), increased or decreased each July 1, following the beginning of the Participant's period of Disability Service, according to the change in the Bureau of Labor Statistics Consumer Price Index (CPI-W) for the preceding 12-month period of Disability Service (or lesser period of Disability Service, if applicable). However, no July 1 increase will exceed an amount which could result in an increase greater than a 5% compounded annual increase since the beginning of the Participant's period of Disability Service, nor in a reduction in the Participant's Final Executive Pay to an amount less than the Participant's Final Executive Pay prior to the period of Disability Service. For purposes of this provision, the Consumer Price Index for the second month previous to any measurement date will be deemed to be in effect on such date. E. The amount of the Disability Service Pension Supplement is the Supplemental Executive Retirement Income, calculated using Final Executive Pay as determined in Section V, subsection 9.D above, and giving credit for Accredited Service and applicable Preference Service for any period of Disability Service, less: 1. The Supplemental Executive Retirement Income calculated without regard to the Disability Service Pension Supplement, 2. The Retirement Income provided by the Pension Plan, and 3. Any amount paid to a retired Participant for lost benefits under the Pension Plan, for the period of Disability Service, under an insurance policy, the premiums for which were paid in whole or in part by CMS Energy Corporation or any subsidiaries which are at least 80% owned, directly or indirectly, by CMS Energy Corporation. F. Payments will begin as of the latter of: 1. The Participant's Normal Retirement Date. 2. The first day of the month following the cessation of any Long Term Disability payments pursuant to any plan or insurance policy, the premiums for which were paid in whole or in part by CMS Energy Corporation, or any of its directly or indirectly wholly owned subsidiaries. SECTION VI. PROVISIONAL PAYEE OPTIONS AND PRE-RETIREMENT SURVIVING SPOUSE BENEFIT 1. POST-RETIREMENT. The provisions of Section VI of the Pension Plan, pertaining to Provisional Payee Options are adopted as part of this Supplemental Plan and any option which is elected by or otherwise applicable to a Participant under the Pension Plan will be identically applicable under the provisions of this Supplemental Plan. A Participant may not have a Provisional Payee Option under this Supplemental Plan which differs from such option or options elected by or otherwise applicable to him under the Pension Plan except that a Participant who has elected a Single Sum under the Pension Plan may name a Provisional Payee 6 7 under this Supplemental Plan. Nevertheless, a Provisional Payee may elect, upon the death of the Participant and the agreement of the SERP Retirement Board, to then receive the present value of the amount of the payments to which he otherwise would be entitled, as determined by the SERP Retirement Board using such actuarial tables and interest assumptions as may be adopted for this purpose by the SERP Retirement Board and in use at the time of the Participant's death. 2. PRE-RETIREMENT SURVIVING SPOUSE BENEFIT. Provisions of Section VI, subsection 2 of the Pension Plan of Consumers Power Company pertaining to Pre-Retirement Surviving Spouse Benefits are adopted as part of this Supplemental Plan. SECTION VII. TERMINATION OF SERVICE If a Participant included in the Supplemental Plan voluntarily terminates his services other than by transfer to an affiliated or associated company as provided by subsection 2 of Section III of this Supplemental Plan, retirement as provided by Section IV of the Pension Plan, or in accordance with the terms of an Employment Agreement effective following a Change in Control as defined in Section XII, the Participant will forfeit all Supplemental Executive Retirement Income except for any amount attributable to Earnings not permitted to be used for benefit calculation under the Pension Plan by the Internal Revenue Code or Regulations thereunder. Any such amount shall be calculated without Preference Service. A Participant whose services are terminated for any reason other than death prior to attaining five years of actual service after inclusion in this Supplemental Plan shall not be eligible for Supplemental Executive Retirement Income. If the Accrued Retirement Income is actuarially reduced because of retirement at an Early Retirement Date, the Accrued Supplemental Executive Retirement Income will be reduced by an identical percentage. SECTION VIII. FORFEITURE A Participant who is discharged by the Company for cause, or an employee who is subsequently convicted of any felony committed while in the course of his employment with the Company, which felony involved theft, malicious destruction or misuse of the property of the Company or the embezzlement or misapplication of the funds of the Company, or who makes an admission in writing of the commission of such felony, shall be ineligible for and forfeit Supplemental Executive Retirement Income. SECTION IX. NON-ALIENATION OF BENEFITS No benefit under the Supplemental Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, charge, renunciation, or reduction and any attempt so to anticipate, alienate, sell, transfer, assign, pledge, encumber, charge, renounce, or reduce the same shall be void, nor shall any such benefit be in any manner liable for or subject to the debts, contracts, liabilities, engagements or torts of the person entitled to such benefit. If any Participant or retired Participant or any Provisional Payee under the Supplemental Plan is adjudicated bankrupt or attempts to anticipate, alienate, sell, transfer, assign, pledge, encumber, charge, renounce, or reduce any benefit under the Supplemental Plan, except as specifically provided in the Supplemental Plan, then such benefit shall cease and terminate and in that event the SERP Retirement Board shall hold or apply the same or any part thereof to or for the benefit of such Participant or retired Participant or Provisional Payee in such manner as the SERP Retirement Board may think proper, provided the SERP Retirement Board shall not act in any manner as would perpetuate the alienations prohibited by this Section. SECTION X. LIMITATION OF RIGHTS Neither the establishment of this Supplemental Plan, nor any modification thereto, nor the payment of any benefits, shall be construed as giving to any Participant, other employee, or other person any legal or 7 8 equitable rights against the Company, or any officer or employee thereof, or the SERP Retirement Board, except as herein provided. Under no circumstances shall the terms of employment of any employee be modified or in any way affected hereby. Inclusion under the Supplemental Plan will not give any Participant or any Provisional Payee any right to claim a Supplemental Executive Retirement Income except to the extent such right is specifically fixed under the terms of the Supplemental Plan. Subject to the provisions of this Supplemental Plan and the Supplemental Executive Retirement Trust the Participant shall have no rights greater than those of a general, unsecured creditor of the Company. SECTION XI. ADMINISTRATION OF SUPPLEMENTAL PLAN The general administration of this Supplemental Plan shall be placed in the SERP Retirement Board provided for in this Supplemental Plan and the provisions of Section XII of the Pension Plan will govern the administration of this Supplemental Plan as far as applicable. The determination of the SERP Retirement Board as to any question or matter arising under this Supplemental Plan shall be conclusive and binding. The claim procedure of this Supplemental Plan shall be the same as the claim procedure provided in the Pension Plan. SECTION XII. AMENDMENT, MODIFICATION OR TERMINATION OF THE SUPPLEMENTAL PLAN This Supplemental Plan may be amended, modified or terminated at any time by action of the Board of Directors of the Company. Notwithstanding any other provisions of this Supplemental Plan, in the event of a Change in Control (as hereinafter defined), each Participant shall be fully vested in any benefit accredited to the Participant as of the date of the Change in Control, and such amount shall not be subject to further vesting requirements or to any forfeiture provisions.
