ARTICLE II - PARTICIPATION

Section 2.1. Participation. Any Person, whether or not a record holder of Common Stock, may elect to participate in the Plan; provided, however, that if such Person is a Foreign Person, he must provide evidence satisfactory to the Administrator that his participation in the Plan would not violate local laws and regulations applicable to the Corporation, the Plan or such Foreign Person; and further, in the case of any Foreign Person, the Administrator, in its sole discretion, may restrict or deny any such Foreign Person’s participation in the Plan if compliance with applicable laws and regulations is not reasonably practicable.

An election by a Person to participate in the Plan shall be made by completing and returning to the Administrator an Account Authorization Form and (i) electing to have Dividends on Eligible Securities of which such Person is the record holder invested in the appropriate class of Common Stock pursuant to Section 2.2 hereof, (ii) depositing certificates representing Common Stock of which such Person is the record holder into the Plan pursuant to Section 4.1 hereof or (iii) making an initial Investment pursuant to Section 2.3 hereof.

Any Person who has met such requirements and has made and not revoked such election is herein referred to as a “Participant.” A Participant may elect to participate in any or all of the forms of investment provided in Sections 2.2 through 2.4 hereof by submitting an Account Authorization Form designating such election to the Administrator.

Section 2.2. Dividend Reinvestment. In addition to the Minimum Dividend Reinvestment Requirement, a Participant may elect to have all or a portion (greater than the Minimum Dividend Reinvestment Requirement) of any Dividend on his Common Stock invested in shares (and/or fractional shares) of the appropriate class of Common Stock to be credited to his Account in lieu of receiving such Dividend directly. Any Dividends payable on CMS Energy Common Stock will be invested only in CMS Energy Common Stock. If the shareholders authorize, and the Corporation issues, shares of any additional class or classes of Common Stock, any Dividend payable upon such class or classes will be invested only in the same class of Common Stock. That portion of the Dividends received on shares of Common Stock not reinvested in Common Stock will be sent to the

Participant by check in the manner otherwise associated with payment of such Dividends or by electronic direct deposit if the Participant has elected the direct deposit option provided in Section 7.7 hereof.

Section 2.3. Initial Investment. A Person not already a Participant may become a Participant by making an initial Investment of at least $250 per class of Common Stock accompanied by a completed Account Authorization Form. (This $250 minimum will be waived if a Person enrolls for automatic investment of at least $50 per month for five consecutive transactions.) A Person, who is already a registered shareholder of Common Stock, may become a Participant by completing and returning an Account Authorization Form. Other than automatic deductions, payments shall be received by personal check payable to “Shareowner Services.” Such payment will be invested in the class of Common Stock indicated on the Account Authorization Form, provided, however, that if no class of Common Stock is indicated on the Account Authorization Form, the initial Investment will be invested in CMS Energy Common Stock.

Section 2.4. Optional Investments. A Participant may elect to make cash payments at any time or from time to time, to the Plan, by personal check payable to “Shareowner Services,” or through automatic deductions from an account at a financial institution (generally, but not limited to, the last banking day of each month) for investment in Common Stock pursuant to Section 3.4 hereof; provided, however, that any Participant who elects to make optional Investments pursuant to this Section 2.4 must invest at least $25 for any single investment and may not invest more than the Maximum Amount. For purposes of determining whether the Maximum Amount has been reached, initial Investments shall be counted as optional Investments. A Participant may elect to purchase any class of Common Stock by making such optional Investments, but each single investment must be at least $25 per class of Common Stock. Optional Investments will be applied to the currently held class of Common Stock unless otherwise indicated. If the Participant holds more than one class of Common Stock, and no designation is made, the funds will be applied to CMS Energy Common Stock.

ARTICLE III - DIVIDEND REINVESTMENT AND STOCK PURCHASE

Section 3.1. Dividend Reinvestment. The Minimum Dividend Reinvestment Requirement, as well as any Dividends as to which reinvestment has been elected by a Participant, shall be paid to the Administrator or its nominee on behalf of such Participant. Dividends shall be reinvested, at the Corporation’s election, in either (i) newly issued shares of Common Stock purchased from the Corporation, or (ii) shares of Common Stock purchased in the open market.

Section 3.2. Dividend Reinvestment in Newly Issued Shares. Dividend reinvestment in newly issued shares of Common Stock shall be governed by this Section 3.2. On an Investment Date with respect to which the Corporation elects to issue new shares to the Plan in order to effect the reinvestment of Dividends, the Corporation shall issue to the Administrator upon the Corporation’s receipt of the funds described in (a) below, for crediting by the Administrator to the Account of a Participant, a number of shares (and/or fractional shares rounded to three decimal places) of Common Stock equal to (a) the amount of any Dividends paid to the Administrator on behalf of such Participant since the preceding Investment Date plus the amount of any Dividends paid to the Administrator on behalf of such Participant on such Investment Date divided by (b) the Corporation Share Purchase Price with respect to the Investment Date. Such shares shall be issued or sold to, and registered in the name of, the Administrator or its nominee as custodian for such Participants. No interest shall be paid on Dividends held pending reinvestment pursuant to this Section 3.2.

Section 3.3. Dividend Reinvestment in Shares Purchased in the Open Market. Dividend reinvestment in shares of Common Stock purchased in the open market shall be governed by this Section 3.3. On an Investment Date with respect to which the Corporation elects to effect reinvestment of Dividends in shares of Common Stock purchased in the open market, the Administrator shall (if it is an Independent Agent), or shall cause an Independent Agent to, apply the amount of any Dividends paid to the Administrator on behalf of the Participants since the preceding Investment Date plus the amount of any Dividends paid to the Administrator on behalf of the Participants on such Investment Date to the purchase of shares of Common Stock in the open market. Purchases in the open market pursuant to this Section 3.3 and Subsection 3.4.2 hereof may be, but are not required to be, made on the applicable Investment Date and should be completed as soon as practicable thereafter, or at a later date as necessary or advisable under applicable law, including without limitation any federal securities laws. Open market

purchases pursuant to this Section 3.3 and Subsection 3.4.2 hereof may be made on any securities exchange on which the Common Stock is traded, in the over-the-counter market or by negotiated transactions, and may be upon such terms and subject to such conditions with respect to price and delivery to which the Independent Agent (including the Administrator if it is also an Independent Agent) may agree. With regard to open market purchases of shares of Common Stock pursuant to this Section 3.3 and Subsection 3.4.2 hereof, none of the Corporation, the Administrator (if it is not also serving as the Independent Agent) or any Participant shall directly or indirectly have any authority or power to control, influence or direct the time, amounts, manner or price at which shares of Common Stock may be purchased, the markets on which such shares are to be purchased (including on any securities exchange, in the over-the-counter market or in negotiated transactions) or the selection of the broker or dealer (other than the Independent Agent) through or from whom purchases may be made, except that the timing of such purchases must be made in accordance with the terms and conditions of the Plan. For the purpose of making, or causing to be made, purchases of shares of Common Stock pursuant to this Section 3.3 and Subsection 3.4.2 hereof, and sales of Account Shares pursuant to Section 5.1 hereof, the Independent Agent shall be entitled to commingle each Participant’s funds with those of all other Participants and to offset purchases of shares of Common Stock against sales of shares of Common Stock to be made for Participants, resulting in a net purchase or a net sale of shares. The number of shares (and/or fractional shares rounded to three decimal places) of Common Stock that shall be credited to a Participant’s Account with respect to an Investment Date to which this Section 3.3 applies shall be equal to (a) (i) the amount of any Dividends paid to the Administrator on behalf of such Participant since the preceding Investment Date plus (ii) the amount of any Dividends paid to the Administrator on behalf of such Participant on such Investment Date divided by (b) the Market Share Purchase Price with respect to such Investment Date. Such shares shall be registered in the name of the Administrator or its nominee as custodian for the Participants. No interest shall be paid on Dividends held pending reinvestment pursuant to this Section 3.3.

Section 3.4. Optional and Initial Investments. Participants can make additional investments by sending a personal check to the Administrator at any time. Cash, money orders, traveler’s checks and third party checks will not be accepted. The check must be payable in U.S. dollars to “Shareowner Services” in an amount of at least $25 and received one Trading Day prior to the investment date. These investments will be made in either (i) newly issued shares of Common Stock in the manner provided in Subsection 3.4.1 hereof, or (ii) Common Stock purchased in the open market in the manner provided in Subsection 3.4.2 hereof. The Administrator reserves the right to place a temporary restriction on Account Shares, subject to verification of the receipt of good funds with respect to any optional or initial Investment.

Subsection 3.4.1 Newly Issued Shares. On an Investment Date with respect to which the Corporation elects to issue new shares of Common Stock to the Plan in order to effect the investment of optional and initial Investments, the Corporation shall issue to the Administrator upon the Corporation’s receipt of the funds described in (a) below, for crediting by the Administrator to the Account of a Participant, a number of shares (and/or fractional shares rounded to three decimal places) of Common Stock equal to (a) the amount of any optional and/or initial Investments received by the Administrator from such Participant since the preceding Investment Date (including any amounts received from such Participant on the preceding Investment Date that were not invested on the preceding Investment Date as set forth in Section 3.4 hereof) divided by (b) the Corporation Share Purchase Price with respect to the Investment Date. Such shares shall be issued or sold to, and registered in the name of, the Administrator or its nominee as custodian for the Participants.

Subsection 3.4.2 Shares Purchased in the Open Market. On an Investment Date with respect to which the Corporation elects to effect the investment of optional and initial Investments in shares of Common Stock purchased in the open market, the Administrator shall forward to the Independent Agent funds equaling (i) the amount of any optional and/or initial Investments received by the Administrator from Participants since the preceding Investment Date (including any amounts received from Participants on the preceding Investment Date that were not invested on the preceding Investment Date as set forth in Section 3.4 hereof) for purchase of Common Stock in the open market. Such purchases shall be made in the manner set forth in this Article III. Such shares shall be registered in the name of the Administrator or its nominee as custodian for the Participants.

ARTICLE IV - SAFEKEEPING SERVICES FOR DEPOSITED COMMON STOCK

Section 4.1. Deposited Common Stock. A Participant may elect to have certificates representing shares of Common Stock of which the Participant is the record holder deposited into the Plan by completing a Transaction Request Form and delivering such certificates and Transaction Request Form to the Administrator. Shares of Common Stock so deposited shall be transferred into the name of the Administrator or its nominee and credited to the depositing Participant’s Account. Dividends paid on shares of Common Stock deposited into the Plan pursuant to this Section 4.1 will be reinvested in the same manner as shares of Common Stock purchased under the Plan and credited to a Participant’s account. If no other shares of Common Stock are credited to the Participant’s Account, the Dividends will be fully reinvested unless a completed Account Authorization Form designates a different election pursuant to Section 2.2 hereof.

Section 4.2. Withdrawal of Common Stock Deposited Pursuant to Section 4.1. Shares of Common Stock deposited pursuant to Section 4.1 hereof may be withdrawn from the Plan pursuant to Section 7.2 hereof.

ARTICLE V - SALE OF ACCOUNT SHARES; GIFT OR TRANSFER OF ACCOUNT SHARES

Section 5.1. Sale of Account Shares. A Participant may request, at any time, that all or a portion of his Account Shares be sold by delivering to the Administrator a completed Transaction Request Form to that effect. The Administrator (if it is not also an Independent Agent) shall forward such sale instructions to the Independent Agent as soon as practicable. (The intent is to forward sale instructions to the Independent Agent as soon as practicable.) The Independent Agent shall generally make such sales as soon as practicable (in accordance with stock transfer requirements and federal and state securities laws) after processing such sale instructions. A check for the proceeds of the sale of Common Stock (in U.S. dollars), less applicable taxes and fees, will generally be mailed by first class mail as soon as administratively possible after the settlement date. If a Participant submits a request to sell all or part of the Plan shares, and the Participant requests net proceeds to be automatically deposited to a checking or savings account, the Participant must provide a voided blank check for a checking account or blank savings deposit slip for a savings account.

If instructions for the sale of shares of Common Stock on which Dividends are being reinvested are received by the Administrator on or after the record date relating to a Dividend Payment Date but before the Investment Date, and (i) if the Participants’ sale instructions cover less than all of the shares of Common Stock credited to their Accounts, the sale will be processed as described above in the immediately preceding paragraph, the Dividends will be invested and the newly purchased shares will be credited to their Accounts or (ii) if the Participants’ sale instructions cover all of the shares of Common Stock credited to their Accounts, the sale instructions will be processed and a check for the Dividend will be provided.

With regard to open market sales of Account Shares pursuant to this Section 5.1, none of the Corporation, the Administrator (if it is not also serving as the Independent Agent) or any Participant shall directly or indirectly have any authority or power to control, influence or direct the time, amounts, manner or price at which shares of Common Stock may be sold, the markets on which such shares are to be sold (including on any securities exchange, in the over-the-counter market or in negotiated transactions) or the selection of the broker or dealer (other than the Independent Agent) through or from whom sales may be made, except that the timing of such sales must be made in accordance with the terms and conditions of the Plan.

Section 5.2. Gift or Transfer of Account Shares. A Participant may elect to transfer (whether by gift, private sale or otherwise) ownership of all or a portion of his Account Shares to the Account of another Participant or establish an Account for a Person not already a Participant by delivering to the Administrator a completed Transaction Request Form.

Account Shares transferred in accordance with the preceding paragraph shall continue to be registered in the name of the Administrator as custodian and shall be credited to the transferee’s Account. If the transferee is not already a Participant, an Account shall be opened in the name of the transferee and the transferor shall, if he so chooses, designate an initial level of reinvestment of Dividends on those Account Shares greater than the Minimum Dividend Reinvestment Requirement. The Administrator shall deliver an Account Statement to such transferee showing the transfer of such Account Shares into his

Account. The transferor may request that the Administrator deliver to such transferee a certificate. The transferor may request that the Administrator send the certificate directly to such transferee or request that the Administrator deliver such gift certificate to the transferor for personal delivery to the transferee. The Administrator shall comply with any such request of a transferor relating to Account Statements and/or certificates as soon as practicable following receipt of such request.

If a completed request for transfer with regard to shares of Common Stock credited to a Participant’s Account on which Dividends are being reinvested is received by the Administrator on or after the record date relating to the Dividend Payment Date but before the Investment Date, the Dividends will be invested in Common Stock through the Plan, and (i) if the Participant’s transfer instructions cover less than all of the shares of Common Stock credited to his Account, the transfer will be processed as described above in the immediately preceding paragraph and the newly purchased shares of Common Stock will be credited to the transferor’s Account or (ii) if the Participant’s transfer instructions cover all of the shares of Common Stock credited to his Account, the transfer instructions will be processed following the Investment Date.

ARTICLE VI - ELIGIBLE SECURITIES

Section 6.1. Eligible Securities. Common Stock shall be Eligible Securities.

Section 6.2. Additional Eligible Securities. The Corporation may from time to time or at any time designate other debt or equity securities of the Corporation and its subsidiaries as Eligible Securities by notifying the Administrator in writing of the designation of such securities as Eligible Securities.

ARTICLE VII - TREATMENT OF ACCOUNTS

Section 7.1. Changing Plan Options. A Participant may elect to change his Dividend reinvestment levels (subject to the Minimum Dividend Reinvestment Requirement) by delivering to the Administrator appropriate instructions. To be effective for a Dividend payment, the Account Authorization Form must be received by the Administrator by the business day prior to the record date relating to such Dividend. If the Account Authorization Form is not received by the Administrator by the business day prior to the record date relating to such Dividend, such instructions shall not become effective until after such payment date. The shares of Common Stock purchased from the reinvestment of such Dividend shall be credited to the Participant’s Account. After the Administrator’s receipt of effective option changing instructions, Dividends as to which the reinvestment election has been revoked will be paid in cash or by direct deposit to the Participant’s designated direct deposit account, if such Participant has elected the direct deposit option pursuant to Section 7.7 hereof.

Section 7.2. Right of Withdrawal. A Participant may, at any time or from time to time, withdraw from the Plan all or any part (other than fractions) of his Account Shares by delivering to the Administrator (i) appropriate written withdrawal instructions to that effect, if such Participant will be the record holder of such Account Shares after withdrawal or (ii) a completed Transaction Request Form if the Participant will not be the record holder of such Account Shares after withdrawal. Subject to the limitations described in the immediately following paragraph, as soon as practicable following the Administrator’s receipt of (i) appropriate withdrawal instructions or (ii) a completed Transaction Request Form, which indicates the Participant’s desire to withdraw certain of his whole Account Shares, the Administrator shall mail by first class mail to the Participant at his address of record, or to the address of any Person that the Participant designated, certificates representing such designated Account Shares or, if requested by the Participant, transfer such designated Account Shares to the DRS.

If a completed request for withdrawal with regard to shares of Common Stock credited to a Participant’s Account on which Dividends are being reinvested is received by the Administrator on or after the record date relating to the Dividend Payment Date but before the Investment Date, and (i) if the Participant’s withdrawal instructions cover less than all of the shares of Common Stock credited to his Account, the withdrawal will be processed as described above in the immediately preceding paragraph, the Dividends will be invested in Common Stock through the Plan, and the newly purchased shares of Common Stock credited to his Account or (ii) if the Participant’s withdrawal instructions cover all of the shares of Common Stock

credited to his Account, the withdrawal instructions will be processed and checks for the Dividends and for the sale of any fractional shares will be provided.

Withdrawal of Account Shares shall not affect reinvestment of Dividends on the shares withdrawn unless (i) the Participant is no longer the record holder of such shares, (ii) such reinvestment is changed by the Participant by delivering to the Administrator written instructions or an Account Authorization Form to that effect pursuant to Section 7.1 hereof or (iii) the Participant has terminated his participation in the Plan.

Other than transfers pursuant to Section 5.2 hereof, shares of Common Stock credited to a Participant’s Account may not be pledged or assigned.

Section 7.3. Right of Termination of Participation. If a Participant’s Transaction Request Form indicates the Participant’s desire to terminate his participation in the Plan, the Administrator shall treat such request as a withdrawal of all of such Participant’s whole Account Shares pursuant to Section 7.2 hereof. The Administrator, in addition to mailing certificates representing all whole Account Shares or transferring Account Shares to DRS, if any, pursuant to Section 7.2 hereof, shall mail by first class mail to the Participant at his address of record checks for an amount equal to the sum of (i) the amount of cash credited to such Participant’s Account pending investment in Common Stock and (ii) the cash value of any fractional shares of Common Stock credited to his Account. Such fractional shares shall be valued at the current market price on the NYSE.

Section 7.4. Stock Splits, Stock Dividends and Rights Offerings. Any shares or other securities representing stock splits or other non-cash distributions on Account Shares shall be credited to such Participant’s Account. Stock splits, combinations, re-capitalizations and similar events affecting the Common Stock shall, as to shares credited to Accounts of Participants, be credited to such Accounts on a pro rata basis.

In the event of a rights offering, a Participant shall receive rights based upon the total number of whole shares of Common Stock credited to his Account.

Section 7.5. Shareholder Materials; Voting Rights. The Administrator shall send or forward to each Participant all applicable proxy solicitation materials, other shareholder materials or consent solicitation materials. Participants shall have the exclusive right to exercise all voting rights respecting Account Shares credited to their respective Accounts. A Participant may vote the Account Shares credited to their respective Account in person or by proxy. A Participant’s proxy card shall represent all Account Shares and shares of Common Stock of which he is the record holder. Account Shares shall not be voted unless a Participant or the proxy votes them.

Solicitation of the exercise of Participants’ voting rights by the management of the Corporation and others under a proxy or consent provision applicable to all holders of Common Stock shall be permitted. Solicitation of the exercise of Participants’ tender or exchange offer rights by management of the Corporation and others shall also be permitted. The Administrator shall notify the Participants of each occasion for the exercise of their voting rights or rights with respect to a tender offer or exchange offer within a reasonable time before such rights are to be exercised. Such notification shall include all information distributed to the shareholders of the Corporation by the Corporation regarding the exercise of such rights.

Section 7.6. Account Statements. When there is activity or at least annually, the Administrator shall send to the Participant an Account Statement reflecting information regarding such Participant’s Account as the Administrator may determine to be pertinent to the Participant.

Section 7.7. Direct Deposit Option. A Participant may elect to have any Dividends on Account Shares not being reinvested in Common Stock pursuant to the Plan directly deposited into a bank account or paid directly by check. To receive such direct deposit of funds, a Participant must appropriately notify the Administrator.

ARTICLE VIII - CERTIFICATES AND FRACTIONAL SHARES

Section 8.1. Certificates. Participants may contact the Administrator to request the Administrator to issue Common Stock in the form of a stock certificate. Please note fractional shares may not be issued in certificate form. Upon the mailing of such certificate the shares of Common Stock represented by such certificate shall no longer be Account Shares but shall remain reinvestment Eligible Securities (except to the extent such Participant has elected not to have Dividends reinvested in Common Stock pursuant to the Plan).

Section 8.2. Fractional Shares. Fractional shares of Common Stock shall be credited to Accounts as provided in Article III hereof; provided, however, that no certificate for fractional shares shall be distributed to any Participant at any time; and provided, further, that the Corporation shall issue and sell only whole shares of Common Stock to the Administrator in respect of Dividends reinvested in, and purchases made by the Administrator hereunder of, newly issued shares.

ARTICLE IX - CONCERNING THE PLAN

Section 9.1. Suspension, Modification and Termination. The Corporation may at any time and from time to time, at its sole option, suspend, modify, amend or terminate the Plan, in whole, in part or in respect of Participants in one or more jurisdictions; provided, however, no such amendment shall decrease the Account of any Participant or result in a distribution to the Corporation of any amount credited to the Account of any Participant. Upon complete termination of the Plan, the Accounts of all Participants (or in the case of partial termination of the Plan, the Accounts of all affected Participants) shall be treated as if each such Participant had elected to terminate his participation in the Plan pursuant to Section 7.3 hereof, except that any fraction of a share of Common Stock shall be valued as of the trading date immediately preceding the date on which the Plan is terminated. The Administrator shall promptly send each affected Participant notice of such suspension, material modification or termination.

Section 9.2. Rules and Regulations. The Corporation may from time to time adopt such administrative rules and regulations concerning the Plan as it deems necessary or desirable for the administration of the Plan. The Corporation shall have the power and authority to interpret the terms and the provisions of the Plan and shall interpret and construe the Plan and reconcile any inconsistency or supply any omitted detail in a manner consistent with the general terms of the Plan and applicable law.

Section 9.3. Costs. The Participants will bear the cost of any brokerage commissions, any related service fees and applicable taxes incurred in connection with open market sales of shares of Common Stock made under the Plan. The Corporation shall pay any brokerage commissions and service fees incurred in connection with any purchase of shares of Common Stock made under the Plan. Any applicable taxes incurred in connection with such open market purchase shall be borne by the Participants.

Section 9.4. Termination by Corporation. If a Participant does not have at least one whole Account Share, the Participant’s participation in the Plan may be terminated by the Corporation, in its sole discretion, upon written notice to such Participant by mail at his address of record. Additionally, the Corporation, in its sole discretion, may terminate any Participant’s participation in the Plan after written notice mailed in advance to such Participant at his address of record. Upon such termination, the Account of such Participant shall be treated as if he had elected to terminate his participation in the Plan pursuant to Section 7.3 hereof, except that any fraction of a share of Common Stock shall be valued as of the trading date immediately preceding the date on which such Participant’s participation is terminated.
