II.      CORPORATE PERFORMANCE GOALS

         2.1      IN GENERAL. The composite Plan Performance Factor will depend
                  on corporate performance in two areas: (1) the ongoing net
                  income per outstanding CMS Energy share (EPS); and (2) the
                  Corporate Free Cash Flow of CMS Energy (CFCF). There will be
                  no payout under the Plan unless a composite Plan Performance
                  Factor of at least 75% is achieved. Each Component as well as
                  the composite Plan Performance Factor to be used for payouts
                  will be capped at a maximum of 200%. A table containing the
                  composite Plan Performance Factors shall be created by the
                  Committee for each Performance Year. The table for Performance
                  Year 2004 is set forth below.

                  (a)      EPS COMPONENT. EPS performance shall constitute 40%
                           of the composite Plan Performance Factor. The 100%
                           EPS goal for the 2004 performance year is $.85 per
                           share, and the EPS component shall increase or
                           decrease by 25% for each $.05 per share change in
                           performance. (Mathematical extrapolation shall be
                           used for actual results not shown in the table.)
                           There will be no payout under the plan unless at
                           least $.80 per share is achieved (regardless of CFCF
                           performance).

                  (b)      CFCF COMPONENT. CFCF performance shall constitute 60%
                           of composite Plan Performance Factor. The 100% CFCF
                           goal for the 2004 performance year is $ (100)
                           million, and the CFCF component shall increase or
                           decrease by 25% for each $50 million change in
                           performance. (Mathematical extrapolation shall be
                           used for actual results not shown in the table.)

III.     ANNUAL AWARD FORMULA

         3.1      OFFICERS' ANNUAL AWARDS. Annual Awards for each eligible
                  Officer will be based upon a standard award percentage of the
                  Officer's Base Salary as in effect on January 1 of the
                  Performance Year. The standard award percentages are set forth
                  in the table below. The maximum amount that can be awarded
                  under this Plan for any Code Section 162(m) Employee will not
                  exceed $2.5 Million in any one Performance Year. The total

                  according to the annual award formula set forth in Section
                  3.2.

                  have been reviewed and approved by the Committee, and provided
                  further that the Annual Award for a particular Performance
                  Year has not been deferred voluntarily pursuant to Section
                  4.2. The amounts required by law to be withheld for income and

                  enrolled at the time the Committee makes the Annual Award. .

         4.2      VOLUNTARY DEFERRED ANNUAL AWARDS.

                  (a)      The payment of all or one-half of a cash Annual Award
                           may be deferred voluntarily at the election of an
                           individual Plan participant. A separate irrevocable
                           election must be made in the calendar year prior to
                           the beginning of the Performance Year. Any Annual
                           Award made by the Committee after termination of
                           employment of an Officer or retirement of an Officer
                           is not eligible for a voluntary deferral and will be
                           paid in full in cash in the year in which the Annual
                           Award is made.

                  (b)      A Voluntary Deferred Annual Award may be paid out in
                           a lump sum or in five or ten annual installments
                           beginning in the first January of the calendar year
                           following retirement or termination of employment. If
                           an Annual Award is paid in annual installments, each
                           year the payment will be a fraction of the balance
                           equal to one over the number of annual installments
                           remaining. In the event of the participant's death,
                           all deferred amounts will be paid in total in January
                           of the calendar year following the year of death.

                  (c)      At the time of electing to voluntarily defer payment,
                           the participant must elect whether the sum deferred
                           will be treated by the Company or Subsidiary, as
                           applicable, in accordance with Paragraph I or
                           Paragraph II below.

                           i.       A Voluntary Deferred Annual Award will be
                                    credited with sums in lieu of interest from
                                    the first day of the month following the
                                    month in which the Annual Award is
                                    determined to the date of payment. The
                                    interest accrual rate will be equivalent to
                                    the U.S. prime rate of interest as reported
                                    in The Wall Street Journal, compounded
                                    quarterly as of the first business day of
                                    January, April, July and October of each
                                    year during the deferral period. The prime
                                    rate in effect on the first business day of
                                    January, April, July and October will be the
                                    prime rate (described above) in effect for
                                    that quarterly period.

                           ii.      A Voluntary Deferred Annual Award will be
                                    treated as if it were invested as an
                                    optional cash payment under the CMS Energy
                                    Stock Purchase Plan including the
                                    accumulation of any dividends. The value of
                                    the deferred sum at the time of payment will
                                    be equal to the number of dollars such an
                                    investment would have been worth as measured
                                    by the purchase price of shares of Common
                                    Stock using the average closing price, as
                                    reported in The Wall Street Journal (NYSE -
                                    composite transactions) for the first five
                                    trading days in the December previous to a
                                    January payout.

                           The amount of any Voluntary Deferred Annual Award is
                           to be satisfied from the general corporate funds of
                           the company on whose payroll the Officer was enrolled
                           prior to the payout beginning and are subject to the
                           claims of general creditors of that company.

         4.3      PAYMENT IN THE EVENT OF DEATH.

                  (a)      A participant may name the beneficiary of his or her
                           choice on a beneficiary form provided by the Company,
                           and the beneficiary shall receive payment in the
                           event that the Participant dies prior to receipt of
                           either a cash Annual Award, a Mandatory Deferred
                           Annual Award or a Voluntary Deferred Annual Award. If
                           a beneficiary is not named, the payment will be made
                           to the first surviving class as follows:

                            1. Widow or Widower
                            2. Children, per capita
                            3. Parents, per capita


                                       6

                            4. Brothers and Sisters, per capita
                            5. Estate of the Deceased

                  (b)      A participant may change beneficiaries at any time,
                           and the change will be effective as of the date the
                           participant completes and signs the beneficiary form,
                           whether or not the participant is living at the time
                           the request is received by the Company. However, the
                           Company or the applicable Subsidiary will not be
                           liable for any payments made before receipt of a
                           written request.

V.       CHANGE OF STATUS

         Payments in the event of a change in status will not apply if no awards
         are made for the performance year.

         5.1      PRO-RATA ANNUAL AWARDS. A new Officer, whether hired or
                  promoted to the position, or an Officer promoted to a higher
                  salary grade during the Performance Year will receive a pro
                  rata Annual Award based on the percentage of the Performance
                  Year in which the employee is in a particular salary grade. An
                  Officer whose salary grade has been lowered, but whose
                  employment is not terminated, during the Performance Year will
                  receive a pro rata Annual Award based on the percentage of the
                  Performance Year in which the employee is in a particular
                  salary grade.

         5.2      TERMINATION. An Officer whose employment is terminated
                  pursuant to a violation of the Company code of conduct or
                  other corporate policies will not be considered for an Annual
                  Award.

         5.3      RESIGNATION. An Officer who resigns during or after a
                  Performance Year will not be eligible for an Annual Award. If
                  the resignation is due to reasons such as a downsizing or
                  reorganization, or the ill health of the Officer or ill health
                  in the immediate family, the Officer may petition the
                  Committee and may be considered, in the discretion of the
                  Committee, for a pro rata Annual Award. The Committee's
                  decision to approve or deny the request for a pro rata Annual
                  Award shall be final.

         5.4      DEATH, DISABILITY, RETIREMENT, LEAVE OF ABSENCE. An Officer
                  whose status as an active employee is changed during the
                  Performance Year due to death, Disability, Retirement, or
                  Leave of Absence will receive a pro rata Annual Award.


VI.      MISCELLANEOUS

         6.1      IMPACT ON BENEFIT PLANS. Payments made under the Plan will be
                  considered as earnings for the Supplemental Executive
                  Retirement Plan (Salary Grades E-3 through E-9) but not for
                  purposes of the Employees' Savings Plan, Pension Plan, or
                  other employee benefit programs.

         6.2      IMPACT ON EMPLOYMENT. Neither the adoption of the Plan nor the
                  granting of any Annual Award under the Plan will be deemed to
                  create any right in any individual to be retained or continued
                  in the employment of the Company or any corporation within the
                  Company's control group.

         6.3      TERMINATION OR AMENDMENT OF THE PLAN. The Company at any time
                  may, in writing, terminate or amend the Plan.

         6.4      GOVERNING LAW. The Plan will be governed and construed in
                  accordance with the laws of the State of Michigan.

         6.5      DISPUTE RESOLUTION. Any disputes related to the Plan should
                  first be brought to the Plan Administrator. If that does not
                  result in a mutually agreeable resolution, then the dispute
                  shall be subject to final and binding arbitration before a
                  single arbitrator selected by the parties to be conducted in
                  Jackson, Michigan. The arbitration will be conducted and
                  finished within 90 days of the selection of the arbitrator.
                  The parties shall share equally the cost of the arbitrator and
                  of conducting the arbitration proceeding, but each party shall
                  bear the cost of its own legal counsel and experts and other
                  out-of-pocket expenditures.
