     or 6.2, shall be eligible for benefits under the Plan.

     (b) 415 Limits. A Participant of a Participating Employer whose benefits
     under the Qualified Plan are limited because of the limitation on benefits
     and contributions under Section 415 of the Code shall be eligible for the
     benefits provided by this Plan.

     (c) Qualified Plan Eligibility. Notwithstanding the foregoing, no employee
     shall be eligible for benefits provided by this Plan until such employee
     has satisfied the eligibility requirements of the Qualified Plan.

     SECTION 5.2. DETERMINATION OF ELIGIBILITY. The Vice President, Human
     Resources shall designate employees as eligible for participation under
     Section 5.1(a). The Vice President, Human Resources may revoke such

     2. Effective as of January 1, 2004, Article 6 "Employers' Obligation" shall
be amended and restated to read as follows:

     SECTION 6.1. QUALIFIED PLAN BENEFIT. The Participating Employers shall pay

     benefits and contributions under Section 415 of the Code, and any other
     provision of the Code or other law that the Committee hereafter designates.

     Qualified Plan but for the exclusion of deferrals under the DTE Energy
     Company Supplemental Savings Plan and the DTE Energy Company Executive

                                                                     Page 1 of 4

     Compensation Plan from the definition of compensation under the option of
     the Qualified Plan applicable to such Participant.

     SECTION 6.2 EXECUTIVE DEFERRED COMPENSATION PLAN BENEFIT. The Participating
     Employers shall credit hypothetical bookkeeping accounts ("Make-Up
     Account") for each Participant with amounts intended to replace benefits
     (but not earnings) under any plan maintained by a Participating Employer
     which is intended to be qualified under Code section 401(a) which are
     reduced as a result of any deferrals under Sections 4.01, 4.02, or 4.03 of
     the DTE Energy Company Executive Deferred Compensation Plan ("EDCP"):

     (a) Traditional Pension Plan Make-Up. The Participating Employer shall
     credit to the Participant's Make-Up Account, an amount equal to the
     difference between (i) the present value, determined under each applicable
     defined benefit plan maintained by a Participating Employer which is
     intended to be qualified under Code section 401(a), including the MCN
     Traditional Option and the DTE Traditional Option of the Qualified Plan
     ("Pension Plan"), of the benefit that the Participant would have been
     entitled to receive under each such Pension Plan but for his election to
     defer any amount under the EDCP, and (ii) the present value, determined
     under each such Pension Plan, of the benefit that the Participant is
     entitled to receive under such Pension Plan. Such contribution shall be

     employment.

     (b) Cash Balance Pension Plan Make-Up. The Participating Employer shall
     credit to the Participant's Make-Up Account an amount equal to the
     additional increment that would have been added to the Participant's
     account under a cash balance defined benefit plan maintained by any
     Participating Employer which is intended to be qualified under Code section
     401(a), excluding the MCN Traditional Option and the DTE Traditional Option
     of the Qualified Plan ("Cash Balance Plan"), but for his election to defer
     any amount under the EDCP. Such contribution shall be determined and
     credited as of the last day of each calendar year.

     SECTION 6.3. PRIOR PLAN PAYMENTS. If a Participant is in pay status as of
     December 31, 2001 under one of the Prior Plans, or has terminated
     employment from a Participating Employer prior to January 1, 2002, the
     amount and method of payment to such Participant shall continue under the
     provisions of the applicable Prior Plan. Such payments shall be made by the
     Participating Employer who last employed the Participant.


                                                                     Page 2 of 4

     3. Effective as of October 1,2003, Subsection (a) of Section 7.1 "Form and
Timing of Payment" shall be amended and restated to read as follows:

     (a) Form of Payment. As of the end of the quarter in which his or her
     Termination Date occurs, the Participant's Plan benefit shall be
     present-valued in accordance with the methodology set forth in the portion
     of the Qualified Plan in which the Participant participates. Payment of a
     Participant's Plan benefit shall be made in cash in accordance with the
     Participant's selection on his or her Distribution Election Form either as
     (1) a joint and 100% survivor annuity, (2) a joint and 50% survivor
     annuity, (3) a single life annuity or (4) in annual payments over a period
     not less than one year and not more than 15 years as selected by the
     Participant. If a Participant has not elected a payment option while he or
     she is actively employed by the Company or a Participating Employer,
     distribution shall be made as a joint and 50% survivor annuity for
     Participants who are married as of the Participant's Termination Date and
     as a single life annuity for Participants who are single as of the
     Participant's Termination Date.

     4. Effective as of October 1, 2003, Subsection (b) of Section 7.1 "Form and
Timing of Payment" shall be amended and restated to read as follows:

     (b) Timing of Payment. A lump sum distribution shall be made as of March 1
     following the Termination Date or, if earlier, March 1 following the end of
     the Plan Year in which the Participant's employment terminated for any
     reason other than death. If a Participant whose employment has terminated
     for any reason other than death has elected to receive his or her
     distribution in the form of an annuity, the timing of the first payment
     shall be consistent with the timing for annuity payments specified in the
     portion of the Qualified Plan in which the Participant participates. If a
     Participant has elected to receive his or her distribution in annual
     installments, the first installment shall be made as of March 1 following
     the Participant's Termination Date or, if earlier, March 1 following the
     end of the Plan Year in which the Participant's employment terminated for
     any reason other than death. All subsequent annual installments shall be
     made on approximately the same date each calendar year thereafter for the
     remainder of the distribution period. The amount of any annual payments
     shall be calculated to pay out over the specified period the Participant's
     Plan benefit as of his or her Termination Date with interest credited
     annually on the declining balance at the Plan Interest Rate. The amount of
     the annual payments to the Participant shall be adjusted as of each
     December 31 to reflect changes in the Plan Interest Rate.

     5. Effective as of October 1,2003, Section 7.3 "Recomputation of Plan
Benefits Upon Reemployment" shall be amended and restated to read as follows:

     SECTION 7.3. RECOMPUTATION OF PLAN BENEFITS UPON REEMPLOYMENT. If a
     Participant entitled to a distribution under the qualified Plan receives
     all or part of his or her Plan benefit and is thereafter reemployed, such
     Participant's Plan benefit shall be recalculated upon the Participant's
     subsequent termination of employment. Plan payments shall cease upon
     reemployment. If a Participant's recalculated Plan benefit


                                                                     Page 3 of 4

<PAGE>

     results in an additional payment to the Participant, such additional
     payment shall be made in accordance with Section 7.1. Such recalculations
     shall be made in accordance with the procedures under the Qualified Plan.
     If such Participant's recalculated Plan benefit shows that the
     Participant's Plan benefit has been overpaid after offsetting for any Plan
     benefits previously received, the Participant shall be required to make
     restitution to the Participating Employer, within a period of twelve months
     of such subsequent termination, in an amount equal to such overpayment,
     plus interest at the Plan Interest Rate.

     6. Effective as of October 1, 2003, Article 8 "Beneficiary in the Event of
Death" shall be amended and restated to read as follows:

     SECTION 8.1. DEATH AFTER COMMENCEMENT OF BENEFITS. If a Participant dies
     after payment of his or her Plan benefit begins in accordance with Section
     7.1, the undistributed balance to which such Participant would have been
     entitled, if any, shall continue to be distributed to the Participant's
     beneficiary (as designated under Section 8.3) in accordance with the method
     of distribution being used prior to the Participant's death.

     SECTION 8.2. DEATH PRIOR TO COMMENCEMENT OF BENEFITS. If a Participant dies
     before distribution of his or her Plan benefit begins in accordance with
     Section 7.1, the Participant's Plan benefit, if any, shall be determined in
     accordance with the surviving spouse provisions of the portion of the
     Qualified Plan in which the Participant participated prior to his or her
     death.

     SECTION 8.3. BENEFICIARY DESIGNATION. Each Participant who has elected to
     receive his or her distribution in the form of a joint and 100% survivor
     annuity or joint and 50% survivor annuity shall have the right to designate
     a contingent annuitant to receive the survivor portion of the annuity
     payment upon the death of such Participant. Each Participant who has
     elected to receive his or her distribution in the form of annual payments
     over a period of one to 15 years shall have the right to designate a
     beneficiary or beneficiaries to receive any undistributed annual payments
     upon the death of such Participant. Any Participant who has elected to
     receive his or her distribution in the form of a single life annuity shall
     not be allowed to designate a beneficiary and benefit payments will cease
     upon the Participant's death.

     This First Amendment to the DTE Energy Company Supplemental Retirement Plan
is executed as of September 29, 2003.
