of ________, 1999, is executed and delivered by Consumers Energy Company, a
Michigan corporation (the "Guarantor"), for the benefit of the Holders (as
defined herein) from time to time of the Common Securities (as defined herein)
of Consumers Energy Company Financing III, a Delaware statutory business trust
(the "Issuer").

         WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the
"Declaration"), dated as of ____________, among the trustees of the Issuer named

the extent set forth in this Common Securities Guarantee, to pay to the Holders
of the Common Securities the Guarantee Payments (as defined herein) and to make
certain other payments on the terms and conditions set forth herein; and

         WHEREAS, the Guarantor is also executing and delivering a guarantee
agreement (the "Preferred Securities Guarantee") in substantially identical

Guarantee.

                         DEFINITIONS AND INTERPRETATION

SECTION 1.1.   Definitions and Interpretation

         In this Common Securities Guarantee, unless the context otherwise
requires:

         (a)   Capitalized terms used in this Common Securities Guarantee but
               not defined in the preamble above have the respective meanings
               assigned to them in this Section 1.1;

         (b)   Terms defined in the Declaration as of the date of execution of
               this Common Securities Guarantee have the same meaning when used
               in this Common Securities Guarantee unless otherwise defined in
               this Common Securities Guarantee;

         (c)   a term defined anywhere in this Common Securities Guarantee has
               the same meaning throughout;

         (d)   all references to "the Common Securities Guarantee" or "this
               Common Securities Guarantee" are to this Common Securities
               Guarantees modified, supplemented or amended from time to time;

         (e)   all references in this Common Securities Guarantee to Articles
               and Sections are to Articles and Sections of this Common
               Securities Guarantee unless otherwise specified; and

         (f)   a reference to the singular includes the plural and vice versa.

         "Guarantee Payments" shall mean the following payments or
distributions, without duplication, with respect to the Common Securities, to
the extent not paid or made by the Issuer: (i) any accrued and unpaid
Distributions (as defined in the Declaration) that are required to be paid on
such Common Securities to the extent the Issuer shall have funds available
therefor, (ii) the redemption price, including all accrued and unpaid
Distributions to the date of redemption (the "Redemption Price") to the extent
the Issuer has funds available therefor, with respect to any Common Securities
called for redemption by the Issuer, and (iii) upon a voluntary or involuntary

with the distribution of Debentures to the Holders in exchange for Common
Securities as provided in the Declaration), the lesser of (a) the aggregate of

SECTION 2.1.   Guarantee

         The Guarantor irrevocably and unconditionally agrees to pay in full to
the Holders the Guarantee Payments (without duplication of amounts theretofore
paid by the Issuer), as and when due, regardless of any defense, right of
set-off or counterclaim which the Issuer may have or assert. The Guarantor's
obligation to make a Guarantee Payment may be satisfied by direct payment of the
required amounts by the Guarantor to the Holders or by causing the Issuer to pay
such amounts to the Holders.


SECTION 2.2.   Waiver of Notice and Demand

         The Guarantor hereby waives notice of acceptance of this Common
Securities Guarantee and of any liability to which it applies or may apply,

notices and demands.

SECTION 2.3.   Obligations Not Affected

         Except as otherwise provided herein, the obligations, covenants,
agreements and duties of the Guarantor under this Common Securities Guarantee
shall in no way be affected or impaired by reason of the happening from time to
time of any of the following:

          (a)  the release or waiver, by operation of law or otherwise, of the
     performance or observance by the Issuer of any express or implied
     agreement, covenant, term or condition relating to the Common Securities to
     be performed or observed by the Issuer;

          (b)  the extension of time for the payment by the Issuer of all or any
     portion of the Distributions, Redemption Price, Liquidation Distribution or
     any other sums payable under the terms of the Common Securities or the
     extension of time for the performance of any other obligation under,
     arising out of, or in connection with, the Common Securities (other than an
     extension of time for payment of Distributions, Redemption Price,
     Liquidation Distribution or other sum payable that results from the
     extension of any interest payment period on the Debentures or any extension
     of the maturity date of the Debentures permitted by the Indenture);

          (c)  any failure, omission, delay or lack of diligence on the part of
     the Holders to enforce, assert or exercise any right, privilege, power or
     remedy conferred on the Holders pursuant to the terms of the Common
     Securities, or any action on the part of the Issuer granting indulgence or
     extension of any kind;

<PAGE>   6


          (d)  the voluntary or involuntary liquidation, dissolution, sale of
     any collateral, receivership, insolvency, bankruptcy, assignment for the
     benefit of creditors, reorganization, arrangement, composition or
     readjustment of debt of, or other similar proceedings affecting, the Issuer
     or any of the assets of the Issuer;

          (e)  any invalidity of, or defect or deficiency in, the Common
     Securities;

          (f)  the settlement or compromise of any obligation guaranteed hereby
     or hereby incurred; or

          (g)  any other circumstance whatsoever that might otherwise constitute
     a legal or equitable discharge or defense of a guarantor, it being the
     intent of this Section 2.3 that the obligations of the Guarantor hereunder
     shall be absolute and unconditional under any and all circumstances.

There shall be no obligation of the Holders to give notice to, or obtain consent
of, the Guarantor with respect to the happening of any of the foregoing.

SECTION 2.4.   Rights of Holders

         The Guarantor expressly acknowledges that any Holder of Common
Securities may institute a legal proceeding directly against the Guarantor to
enforce its rights under this Common Securities Guarantee, without first
instituting a legal proceeding against the Issuer or any other Person.

SECTION 2.5.   Guarantee of Payment

         This Common Securities Guarantee creates a guarantee of payment and not
of collection.

SECTION 2.6.   Subrogation

         The Guarantor shall be subrogated to all (if any) rights of the Holders
of Common Securities against the Issuer in respect of any amounts paid to such
Holders by the Guarantor under this Common Securities Guarantee; provided,
however, that the Guarantor shall not (except to the extent required by
mandatory provisions of law) be entitled to enforce or exercise any right that
it may acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Common Securities
Guarantee, if, at the time of any such payment, any amounts are due and unpaid
under this Common Securities Guarantee. If any amount shall be paid to the
Guarantor in violation of the preceding sentence, the Guarantor agrees to hold
such amount in trust for the Holders and to pay over such amount to the Holders.

SECTION 2.7.   Independent Obligations

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Common
Securities and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Common
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 2.3 hereof.

respect to, any of its capital stock, (b) the Guarantor shall not make any

rank pari passu with or junior to the Debentures or (c) the Guarantor shall not
make any guarantee payments with respect to the foregoing (other than pursuant

Guarantor may declare and pay a stock dividend where the dividend stock is the
same stock as that on which the dividend is being paid.

SECTION 3.2.   Ranking

         This Common Securities Guarantee will constitute an unsecured
obligation of the Guarantor and will rank (i) subordinate and junior in right of
payment to all other liabilities of the Guarantor, (ii) pari passu with the most
senior preferred or preference stock now or hereafter issued by the Guarantor
and with any guarantee now or hereafter entered into by the Guarantor in respect
of any preferred or preference stock of any Affiliate of the Guarantor, and
(iii) senior to the Guarantor's common stock.


                                   ARTICLE IV.
                                   TERMINATION

SECTION 4.1.   Termination

         This Common Securities Guarantee shall terminate (i) upon full payment
of the Redemption Price of all Common Securities, (ii) upon the distribution of
the Debentures to the Holders of all of the Common Securities, or (iii) or upon
full payment of the amounts payable in accordance with the Declaration upon
liquidation of the Issuer. Notwithstanding the foregoing, this Common Securities
Guarantee will continue to be effective or will be reinstated, as the case may
be, if at any time any Holder of Common Securities must restore payment of any
sums paid under the Common Securities or under this Common Securities Guarantee.
