CONSUMERS ENERGY COMPANY

FIRST MORTGAGE BOND
2007-1 COLLATERAL SERIES (INTEREST BEARING)

     This bond is one of the bonds of a series designated as First Mortgage Bonds, 2007-1 Collateral Series (Interest Bearing) (sometimes herein referred to as the “2007-1 Collateral Bonds”) issued under and in accordance with and secured by an Indenture dated as of September 1, 1945, given by the Company (or its predecessor, Consumers Power Company, a Maine corporation) to City Bank Farmers Trust Company (The Bank of New York, successor) (hereinafter sometimes referred to as the “Trustee”), together with indentures supplemental thereto, heretofore or hereafter executed, to which indenture and indentures supplemental thereto (hereinafter referred to collectively as the “Indenture”) reference is hereby made for a description of the property mortgaged and pledged, the nature and extent of the security and the rights, duties and immunities thereunder of the Trustee and the rights of the holders of said bonds and of the Trustee and of the Company in respect of such security, and the limitations on such rights. By the terms of the Indenture, the bonds to be secured thereby are issuable in series which may vary as to date, amount, date of maturity, rate of interest and in other respects as provided in the Indenture.

     The 2007-1 Collateral Bonds are to be issued and delivered to the Agent in order to evidence and secure the obligation of the Company under the Credit Agreement to make payments to the Banks under the Credit Agreement and to provide the Banks the benefit of the lien of the Indenture with respect to the 2007-1 Collateral Bonds.

     The obligation of the Company to make payments with respect to the principal of 2007-1 Collateral Bonds shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the then due principal of the Loans and/or the Reimbursement Obligations included in the Obligations shall have been fully or partially paid. Satisfaction of any obligation to the extent that payment is made with respect to

the Loans and/or the Reimbursement Obligations means that if any payment is made on the principal of the Loans and/or the Reimbursement Obligations, a corresponding payment obligation with respect to the principal of the 2007-1 Collateral Bonds shall be deemed discharged in the same amount as the payment with respect to the Loans and/or the Reimbursement Obligations discharges the outstanding obligation with respect to such Loans and/or Reimbursement Obligations. No such payment of principal shall reduce the principal amount of the 2007-1 Collateral Bonds.

     The obligation of the Company to make payments with respect to the interest on 2007-1 Collateral Bonds shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the then due interest and/or fees under the Credit Agreement shall have been fully or partially paid. Satisfaction of any obligation to the extent that payment is made with respect to the interest and/or fees under the Credit Agreement means that if any payment is made on the interest and/or fees under the Credit Agreement, a corresponding payment obligation with respect to the interest on the 2007-1 Collateral Bonds shall be deemed discharged in the same amount as the payment with respect to the Loans and/or the Reimbursement Obligations discharges the outstanding obligation with respect to such Loans and/or Reimbursement Obligations.

     The Trustee may at any time and all times conclusively assume that the obligation of the Company to make payments with respect to the principal of and interest on this bond, so far as such payments at the time have become due, has been fully satisfied and discharged unless and until the Trustee shall have received a written notice from the Agent stating (i) that timely payment of principal and interest on the 2007-1 Collateral Bonds has not been made, (ii) that the Company is in arrears as to the payments required to be made by it to the Agent in connection with the Obligations pursuant to the Credit Agreement, and (iii) the amount of the arrearage.

     If an Event of Default (as defined in the Credit Agreement) with respect to the payment of the principal of the Loans and/or the Reimbursement Obligations shall have occurred, it shall be deemed to be a default for purposes of Section 11.01 of the Indenture in the payment of the principal of the 2007-1 Collateral Bonds equal to the amount of such unpaid principal or Reimbursement Obligations (but in no event in excess of the principal amount of the 2007-1 Collateral Bonds). If an Event of Default (as defined in the Credit Agreement) with respect to the payment of interest on the Loans and/or the Reimbursement Obligations or any fees shall have occurred, it shall be deemed to be a default for purposes of Section 11.01 of the Indenture in the payment of the interest on the 2007-1 Collateral Bonds equal to the amount of such unpaid interest or fees.

     This bond is not redeemable except upon written demand of the Agent following the occurrence of an Event of Default under the Credit Agreement and the acceleration of the Obligations, as provided in Section 9.2 of the Credit Agreement. This bond is not redeemable by the operation of the improvement fund or the maintenance and replacement provisions of the Indenture or with the proceeds of released property.

     In case of certain defaults as specified in the Indenture, the principal of this bond may be declared or may become due and payable on the conditions, at the time, in the manner and with

the effect provided in the Indenture. The holders of certain specified percentages of the bonds at the time outstanding, including in certain cases specified percentages of bonds of particular series, may in certain cases, to the extent and as provided in the Indenture, waive certain defaults thereunder and the consequences of such defaults.

     The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than seventy-five per centum in principal amount of the bonds (exclusive of bonds disqualified by reason of the Company’s interest therein) at the time outstanding, including, if more than one series of bonds shall be at the time outstanding, not less than sixty per centum in principal amount of each series affected, to effect, by an indenture supplemental to the Indenture, modifications or alterations of the Indenture and of the rights and obligations of the Company and the rights of the holders of the bonds and coupons; provided, however, that no such modification or alteration shall be made without the written approval or consent of the holder hereof which will (a) extend the maturity of this bond or reduce the rate or extend the time of payment of interest hereon or reduce the amount of the principal hereof, or (b) permit the creation of any lien, not otherwise permitted, prior to or on a parity with the lien of the Indenture, or (c) reduce the percentage of the principal amount of the bonds the holders of which are required to approve any such supplemental indenture.

     The Company reserves the right, without any consent, vote or other action by holders of the 2007-1 Collateral Bonds or any other series created after the Sixty-eighth Supplemental Indenture, to amend the Indenture to reduce the percentage of the principal amount of bonds the holders of which are required to approve any supplemental indenture (other than any supplemental indenture which is subject to the proviso contained in the immediately preceding sentence) (a) from not less than seventy-five per centum (including sixty per centum of each series affected) to not less than a majority in principal amount of the bonds at the time outstanding or (b) in case fewer than all series are affected, not less than a majority in principal amount of the bonds of all affected series, voting together.

     No recourse shall be had for the payment of the principal of or interest on this bond, or for any claim based hereon, or otherwise in respect hereof or of the Indenture, to or against any incorporator, stockholder, director or officer, past, present or future, as such, of the Company, or of any predecessor or successor company, either directly or through the Company, or such predecessor or successor company, or otherwise, under any constitution or statute or rule of law, or by the enforcement of any assessment or penalty, or otherwise, all such liability of incorporators, stockholders, directors and officers, as such, being waived and released by the holder and owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Indenture.

     This bond shall be exchangeable for other registered bonds of the same series, in the manner and upon the conditions prescribed in the Indenture, upon the surrender of such bonds at the Investor Services Department of the Company, as transfer agent. However, notwithstanding the provisions of Section 2.05 of the Indenture, no charge shall be made upon any registration of transfer or exchange of bonds of said series other than for any tax or taxes or other governmental charge required to be paid by the Company.

     The Agent shall surrender this bond to the Trustee when all of the principal of and interest on the Loans and Reimbursement Obligations arising under the Credit Agreement, and all of the fees payable pursuant to the Credit Agreement with respect to the Obligations shall have been duly paid, and the Credit Agreement shall have been terminated.

     SECTION 1. There is hereby created a series of bonds (the “2007-1 Collateral Bonds”) designated as hereinabove provided, which shall also bear the descriptive title “First Mortgage Bond”, and the forms thereof shall be substantially as hereinbefore set forth (collectively, the “Sample Bond”). The 2007-1 Collateral Bonds shall be issued in the aggregate principal amount of $500,000,000, shall mature on the Termination Date (as such term is defined in the Credit Agreement) and shall be issued only as registered bonds without coupons in denominations of $1,000 and any multiple thereof. The serial numbers of the Collateral Bonds shall be such as may be approved by any officer of the Company, the execution thereof by any such officer either manually or by facsimile signature to be conclusive evidence of such approval. The Collateral Bonds are to be issued to and registered in the name of the Agent under the Credit Agreement (as

such terms are defined in the Sample Bonds) to evidence and secure any and all Obligations (as such term is defined in the Credit Agreement) of the Company under the Credit Agreement.

     The 2007-1 Collateral Bonds shall bear interest as set forth in the Sample Bond. The principal of and the interest on said bonds shall be payable as set forth in the Sample Bond.

     The obligation of the Company to make payments with respect to the principal of 2007-1 Collateral Bonds shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the then due principal of the Loans and/or the Reimbursement Obligations included in the Obligations shall have been fully or partially paid. Satisfaction of any obligation to the extent that payment is made with respect to the Loans and/or the Reimbursement Obligations means that if any payment is made on the principal of the Loans and/or the Reimbursement Obligations, a corresponding payment obligation with respect to the principal of the 2007-1 Collateral Bonds shall be deemed discharged in the same amount as the payment with respect to the Loans and/or the Reimbursement Obligations discharges the outstanding obligation with respect to such Loans and/or Reimbursement Obligations. No such payment of principal shall reduce the principal amount of the 2007-1 Collateral Bonds.

     The obligation of the Company to make payments with respect to interest on 2007-1 Collateral Bonds shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the then due interest and/or fees under the Credit Agreement shall have been fully or partially paid. Satisfaction of any obligation to the extent that payment is made with respect to the interest and/or fees under the Credit Agreement means that if any payment is made on the interest and/or fees under the Credit Agreement, a corresponding payment obligation with respect to the interest on the 2007-1 Collateral Bonds shall be deemed discharged in the same amount as the payment with respect to the interest and/or fees discharges the outstanding obligation with respect to such interest and/or fees.

     The Trustee may at any time and all times conclusively assume that the obligation of the Company to make payments with respect to the principal of and interest on the Collateral Bonds, so far as such payments at the time have become due, has been fully satisfied and discharged unless and until the Trustee shall have received a written notice from the Agent stating (i) that timely payment of principal and interest on the 2007-1 Collateral Bonds has not been made, (ii) that the Company is in arrears as to the payments required to be made by it to the Agent pursuant to the Credit Agreement, and (iii) the amount of the arrearage.

     The Collateral Bonds shall be exchangeable for other registered bonds of the same series, in the manner and upon the conditions prescribed in the Indenture, upon the surrender of such bonds at the Investor Services Department of the Company, as transfer agent. However, notwithstanding the provisions of Section 2.05 of the Indenture, no charge shall be made upon any registration of transfer or exchange of bonds of said series other than for any tax or taxes or other governmental charge required to be paid by the Company.

     SECTION 2. The Collateral Bonds are not redeemable by the operation of the maintenance and replacement provisions of this Indenture or with the proceeds of released property.

     SECTION 3. Upon the occurrence of an Event of Default under the Credit Agreement and the acceleration of the Obligations, the Collateral Bonds shall be redeemable in whole upon receipt by the Trustee of a written demand from the Agent stating that there has occurred under the Credit Agreement both an Event of Default and a declaration of acceleration of the Obligations and demanding redemption of the Collateral Bonds (including a description of the amount of principal, interest and fees which comprise such Obligations). The Company waives any right it may have to prior notice of such redemption under the Indenture. Upon surrender of the Collateral Bonds by the Agent to the Trustee, the Collateral Bonds shall be redeemed at a redemption price equal to the aggregate amount of the Obligations.

     SECTION 4. The Company reserves the right, without any consent, vote or other action by the holder of the Collateral Bonds or of any subsequent series of bonds issued under the Indenture, to make such amendments to the Indenture, as supplemented, as shall be necessary in order to amend Section 17.02 to read as follows:

     SECTION 17.02. With the consent of the holders of not less than a majority in principal amount of the bonds at the time outstanding or their attorneys-in-fact duly authorized, or, if fewer than all series are affected, not less than a majority in principal amount of the bonds at the time outstanding of each series the rights of the holders of which are affected, voting together, the Company, when authorized by a resolution, and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or modifying the rights and obligations of the Company and the rights of the holders of any of the bonds and coupons; provided, however, that no such supplemental indenture shall (1) extend the maturity of any of the bonds or reduce the rate or extend the time of payment of interest thereon, or reduce the amount of the principal thereof, or reduce any premium payable on the redemption thereof, without the consent of the holder of each bond so affected, or (2) permit the creation of any lien, not otherwise permitted, prior to or on a parity with the lien of this Indenture, without the consent of the holders of all the bonds then outstanding, or (3) reduce the aforesaid percentage of the principal amount of bonds the holders of which are required to approve any such supplemental indenture, without the consent of the holders of all the bonds then outstanding. For the purposes of this Section, bonds shall be deemed to be affected by a supplemental indenture if such supplemental indenture adversely affects or diminishes the rights of holders thereof against the Company or against its property. The Trustee may in its discretion determine whether or not, in accordance with the foregoing, bonds of any particular series would be affected by any

supplemental indenture and any such determination shall be conclusive upon the holders of bonds of such series and all other series. Subject to the provisions of Sections 16.02 and 16.03 hereof, the Trustee shall not be liable for any determination made in good faith in connection herewith.

     Upon the written request of the Company, accompanied by a resolution authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of bondholders as aforesaid (the instrument or instruments evidencing such consent to be dated within one year of such request), the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture.

     It shall not be necessary for the consent of the bondholders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof.

     The Company and the Trustee, if they so elect, and either before or after such consent has been obtained, may require the holder of any bond consenting to the execution of any such supplemental indenture to submit his bond to the Trustee or to ask such bank, banker or trust co
