                             CMS ENERGY CORPORATION

    CMS Energy Corporation, a Michigan corporation ("CMS Energy"), incorporated
in 1987, is the parent holding company of Consumers Energy Company ("Consumers")
and CMS Enterprises Company ("Enterprises"). Consumers, a combination electric
and gas utility company serving in all 68 counties of Michigan's Lower
Peninsula, is the largest subsidiary of CMS Energy. Consumers' customer base
includes a mix of residential, commercial and diversified industrial customers,
the largest segment of which is the automotive industry. Enterprises is engaged
in several domestic and international energy-related businesses including: (i)
oil and gas exploration and production; (ii) acquisition, development and
operation of independent power production facilities; (iii) energy marketing,
services and trading; (iv) storage, transmission and processing of natural gas;
and (v) international energy distribution.

    CMS Energy conducts its principal operations through the following six
business segments: (i) electric utility operations; (ii) gas utility operations;
(iii) oil and gas exploration and production operations; (iv) independent power
production; (v) energy marketing, services and trading; and (vi) storage,
transmission and processing of natural gas. Consumers or Consumers' subsidiaries
are engaged in two segments: electric operations and gas operations. Consumers'
electric and gas businesses are principally regulated utility operations. CMS
Energy and its subsidiaries routinely evaluate, invest in, acquire and divest
energy-related assets and/or companies both domestically and internationally.
Consideration for such transactions may involve the delivery of cash or
securities.

    CMS Energy's 1997 consolidated operating revenue was $4.8 billion. This
consolidated operating revenue was derived from its electric utility operations
(approximately 53%), its gas utility operations (approximately 25%), marketing,
services and trading (approximately 14%), independent power production and other
non-utility activities (approximately 4%), gas transmission, storage and
processing activities (approximately 2%), and oil and gas exploration and
production activities (approximately 2%). Consumers' consolidated operations in
the electric and gas utility businesses account for the majority of CMS Energy's
total assets, revenue and income. The unconsolidated share of non-utility
independent power production, gas transmission and storage, marketing services
and trading, and international energy distribution revenue for 1997 was $913
million.

    Consumers is a public utility serving gas or electricity to almost six
million of Michigan's nine and a half million residents in Michigan's Lower
Peninsula. Industries in Consumers' service area include automotive, metal,
chemical, food and wood products industries and a diversified group of other
industries. Consumers' 1997 consolidated operating revenue of $3.8 billion was
derived approximately 67% from its electric utility business, approximately 32%
from its gas utility business and approximately 1% from its non-utility
business. Consumers' rates and certain other aspects of its business are subject
to the jurisdiction of the Michigan Public Service Commission (the "MPSC") and
the Federal Energy Regulatory Commission. Consumers' nuclear operations are
subject to the jurisdiction of the Nuclear Regulatory Commission.

    CMS Energy and its subsidiaries routinely evaluate, invest in, acquire and
divest energy-related assets and/or businesses both domestically and
internationally. Consideration for such transactions may involve the delivery of
cash or securities.

    The foregoing information concerning CMS Energy and it subsidiaries does not
purport to be comprehensive. For additional information concerning CMS Energy
and its subsidiaries' business and affairs, including their capital requirements
and external financing plans, pending legal and regulatory proceedings and
descriptions of certain laws and regulations to which those companies are

                         DESCRIPTION OF DEBT SECURITIES

    The unsecured senior debt securities ("Senior Debt Securities") will be
issued under an Indenture dated as of September 15, 1992, as amended and
supplemented (the "Senior Debt Indenture"), between CMS Energy and NBD Bank, as
Trustee (the "Senior Debt Trustee"), and the unsecured subordinated debt
securities ("Subordinated Debt Securities") will be issued under an Indenture
dated as of June 1, 1997, as amended and supplemented (the "Subordinated Debt
Indenture"), between CMS Energy and The Bank of New Yorks Trustee (the
"Subordinated Debt Trustee"). The descriptions of the provisions of the Senior
Debt Securities and the Subordinated Debt Securities (together the "Debt
Securities" or "Offered Securities"), the Senior Debt Indenture and the
Subordinated Debt Indenture contained herein are brief summaries of such
provisions and do not purport to be complete. The forms of the Senior Debt
Indenture and the Subordinated Debt Indenture are filed as exhibits to the
Registration Statement of which this prospectus is a part, and reference is made
thereto for the respective definitive provisions of such Indentures. The
descriptions herein are qualified in their entirety by such reference. Certain
capitalized terms used herein shall have the meanings respectively set forth in
the respective Indentures. Section references below are references to sections
of the respective Senior Debt Indenture and Subordinated Debt Indenture.

    Specific terms of the particular unsecured senior or subordinated debt
securities in respect of which this prospectus is being delivered, will be set
forth in an accompanying prospectus supplement or supplements, together with the
terms of the offering of the unsecured senior or subordinated debt securities,
the initial price thereof and the net proceeds from the sale thereof. Each
prospectus supplement will set forth with regard to the particular unsecured
senior or subordinated debt securities, without limitation, the designation,
aggregate principal amount, denomination, maturity, any exchange, conversion,
redemption or sinking fund provisions, provisions for redemption at the option
of the holder, interest rate (which may be fixed or variable), the time and
method of calculating interest payments, the right of CMS Energy, if any, to
defer payment of interest on the unsecured senior or subordinated debt
securities and the maximum length of such deferral period, any listing on a
securities exchange and other specific terms of the offering.

GENERAL

    CMS Energy will offer under this prospectus unsecured Debt Securities, any
of which may be issued as: (a) Senior Debt Securities or (b) Subordinated Debt
Securities. The terms of any Debt Securities may or may not restrict the
issuance by CMS Energy or its subsidiaries of additional indebtedness which is
secured, unsecured, senior, pari passu or subordinated to such Debt Securities.

    CMS Energy is a holding company and its assets consist primarily of
investments in its subsidiaries. The Debt Securities will be obligations
exclusively of CMS Energy. CMS Energy's ability to service its indebtedness,
including the Debt Securities, is dependent primarily upon the earnings of its
subsidiaries and the distribution or other payment of such earnings to CMS
Energy in the form of dividends, loans or advances, and repayment of loans and
advances from CMS Energy. The subsidiaries are separate and distinct legal
entities and have no obligation, contingent or otherwise, to pay any amounts due
pursuant to the Debt Securities or to make any funds available therefor, whether
by dividends, loans or other payments.

    A substantial portion of the consolidated liabilities of CMS Energy have
been incurred by its subsidiaries. Therefore, CMS Energy's rights and the rights
of its creditors, including holders of Debt Securities, to participate in the
distribution of assets of any subsidiary upon the latter's liquidation or
reorganization will be subject to prior claims of the subsidiary's creditors,
including trade creditors, except to the extent that CMS Energy may itself be a
creditor with recognized claims against the subsidiary (in which case the claims
of CMS Energy would still be subject to the prior claims of any secured creditor
of such subsidiary and of any holder of indebtedness of such subsidiary that is
senior to that held by CMS Energy).

    As of September 30, 1998, CMS Energy had outstanding approximately $2,321
million aggregate principal amount of indebtedness, none of which was secured.
None of such indebtedness would be senior to any Senior Debt Securities which
may be issued. All of such indebtedness would be senior to any Subordinated Debt
Securities which may be issued. The Indenture, as supplemented, pursuant to
which the Senior Debt Securities will be issued, contains certain limitations on
the issuance of additional debt by CMS Energy, but indebtedness issued within
such limitations could be secured and therefore senior to unsecured Senior Debt
Securities. The Indenture pursuant to which the Subordinated Debt Securities
will be issued contains no limitation on the issuance of indebtedness ranking
senior to the Subordinated Debt Securities.

SENIOR DEBT SECURITIES

    General. The Senior Debt Securities will be issuable under the Senior Debt
Indenture. The Senior Debt Indenture does not limit the aggregate principal
amount of Senior Debt Securities which may be issued thereunder. Senior Debt
Securities may be issued under the Senior Debt Indenture from time to time in
one or more series. The Senior Debt Securities shall mature on a date not less
than nine month, or more than 40 years after the date of issuance. Capitalized
terms used in this section "Senior Debt Securities" and not otherwise
specifically defined in this prospectus shall have the meanings respectively set
forth in the Senior Debt Indenture.

    Exchange and Transfer. Senior Debt Securities may be presented for exchange
and registered Senior Debt Securities may be presented for registration of
transfer at the offices and subject to the restrictions set forth therein and in
the applicable prospectus supplement without service charge, but upon payment of
any taxes or other governmental charges due in connection therewith, subject to
any applicable limitations contained in the Senior Debt Indenture. Senior Debt
Securities in bearer form and the coupons appertaining thereto, if any, will be
transferable by delivery.

    Payment. Unless otherwise indicated in the applicable prospectus supplement,
payment of the principal of and the premium and interest, if any, on all Senior

Unless otherwise indicated in the applicable prospectus supplement, payment of
any interest due on Senior Debt Securities in registered form will be made to
the Persons in whose name such Senior Debt Securities are registered at the
close of business on the Record Date for such interest payments.

    Events of Default. The occurrence of any of the following events with
respect to the Senior Debt Securities of any series will constitute an "Event of
Default" with respect to the Senior Debt Securities of such series: (a) default
for 30 days in the payment of any interest on any of the Senior Debt Securities
of such series; (b) default in the payment when due of any of the principal of
or the premium, if any, on any of the Senior Debt Securities of such series,
whether at maturity, upon redemption, acceleration or otherwise; (c) default in
the deposit or payment of any sinking fund or analogous payment in respect of
any Senior Debt Securities of such series; (d) default for 60 days by CMS Energy
in the observance or performance of any other covenant or agreement contained in

certain events of bankruptcy, insolvency or reorganization relating to CMS
Energy or Consumers; (f) entry of final judgments against CMS Energy or
Consumers aggregating in excess of $25,000,000 which remain undischarged or
unbonded for 60 days; or (g) a default resulting in the acceleration of
indebtedness of CMS Energy or Consumers in excess of $25,000,000, which
acceleration has not been rescinded or annulled within 10 days after written
notice of such default as provided in the Senior Debt Indenture. Additional
Events of Default may be prescribed for the benefit of the Holders of a
particular series of Senior Debt Securities and will be described in the
prospectus supplement relating to such Senior Debt Securities.

    If an Event of Default on any series of Senior Debt Securities shall have
occurred and be continuing, either the Senior Debt Trustee or the Holders of not
less than 25% in aggregate principal amount of the Senior Debt Securities of
such series then Outstanding may declare the principal of all Senior Debt
Securities of such series and the premium thereon and interest, if any, accrued
thereon to be due and payable immediately.

    Upon certain conditions, any such declarations may be rescinded and annulled
if all Events of Default, other than the nonpayment of accelerated principal,
with respect to the Senior Debt Securities of all such affected series then
Outstanding shall have been cured or waived as provided in the Senior Debt
Indenture by the Holders of a majority in aggregate principal amount of the
Senior Debt Securities of the affected series then Outstanding.

                                       6
<PAGE>   10

    Reference is made to the prospectus supplement relating to any series of
Original Issue Discount Securities for the particular provisions relating to the
acceleration of a portion of the principal amount thereof upon the occurrence
and continuance of an Event of Default with respect thereto.

    The Senior Debt Indenture provides that the Senior Debt Trustee will be
under no obligation to exercise any of its rights or powers under the Senior
Debt Indenture at the request, order or direction of the Holders of the Senior
Debt Securities, unless such Holders shall have offered to the Senior Debt
Trustee reasonable indemnity. Subject to such provisions for indemnity and
certain other limitations contained in the Senior Debt Indenture, the Holders of
a majority in aggregate principal amount of the Senior Debt Securities of each
affected series then Outstanding (voting as one class) will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Senior Debt Trustee, or exercising any trust or power conferred
on the Senior Debt Trustee, with respect to the Senior Debt Securities of such
affected series.

    The Senior Debt Indenture provides that no Holder of Senior Debt Securities
may institute any action against CMS Energy under the Senior Debt Indenture
(except actions for payment of overdue principal, premium or interest) unless
such Holder previously shall have given to the Senior Debt Trustee written
notice of default and continuance thereof and unless the Holders of not less
than 25% in aggregate principal amount of Senior Debt Securities of the affected
series then Outstanding (voting as one class) shall have requested the Senior
Debt Trustee to institute such action and shall have offered the Senior Debt
Trustee reasonable indemnity, the Senior Debt Trustee shall not have instituted
such action within 60 days of such request and the Senior Debt Trustee shall not
have received direction inconsistent with such request by the Holders of a
majority in aggregate principal amount of the Senior Debt Securities of the
affected series then Outstanding (voting as one class).

    The Senior Debt Indenture requires CMS Energy to furnish to the Senior Debt
Trustee annually a statement as to CMS Energy's compliance with all conditions
and covenants under the Senior Debt Indenture. The Senior Debt Indenture
provides that the Senior Debt Trustee may withhold notice to the Holders of the
Senior Debt Securities of any series of any default affecting such series
(except defaults as to payment of principal, premium of interest on the Senior
Debt Securities of such series) if it considers such withholding to be in the
interests of the Holders of the Senior Debt Securities of such series.

    Consolidation, Merger or Sale of Assets. The Senior Debt Indenture provides
that CMS Energy may consolidate with or merge into, or sell, lease or convey its
property as an entirety or substantially as an entirety to, any other
corporation if such corporation assumes the obligations of CMS Energy under the
Senior Debt Securities and the Senior Debt Indenture and is organized and
existing under the laws of the United States of America, any state thereof or
the District of Columbia.

    Modification of the Senior Debt Indenture. The Senior Debt Indenture permits
CMS Energy and the Senior Debt Trustee to enter into supplemental indentures
thereto without the consent of the Holders of the Senior Debt Securities to:

    (A)  Secure the Senior Debt Securities of one or more series;

    (B)  Evidence the assumption by a successor corporation of the obligations
         of CMS Energy under the Senior Debt Indenture and the Senior Debt
         Securities then Outstanding;

    (C)  Add covenants for the protection of the Holders of the Senior Debt
         Securities;

    (D)  Cure any ambiguity or correct any defect or inconsistency in the Senior
         Debt Indenture or to make such other provisions as CMS Energy deems
         necessary or desirable with respect to matters or questions arising
         under the Senior Debt Indenture, provided that no such action adversely
         affects the interests of any Holders of Senior Debt Securities;

    (E)  Establish the form and terms of any series of securities under the
         Senior Debt Indenture; and

    (F)  Evidence the acceptance of appointment by a successor Senior Debt
         Trustee.


                                       7
<PAGE>   11

    The Senior Debt Indenture also permits CMS Energy and the Senior Debt
Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Senior Debt Securities of all series then
Outstanding and affected (voting as one class), to enter into supplemental
indentures to add any provisions to, or change in any matter or eliminate any of
the provisions of, the Senior Debt Indenture or modify in any manner the rights
of the Holders of the Senior Debt Securities of each such affected series;
provided, however, that CMS Energy and the Senior Debt Trustee may not, without
the consent of the Holder of each Senior Debt Security then outstanding and
affected thereby, enter into any supplemental indenture to:

    (A)  Change the time of payment of the principal (or any installment of
         principal) of any Senior Debt Security, or reduce the principal amount
         thereof, or reduce the rate or change the time of payment of interest
         thereon, or reduce the amount payable on any Original Issue Discount
         Securities upon acceleration or provable in bankruptcy, or impair the
         right to institute suit for the enforcement of any payment on any
         Senior Debt Security when due; or

    (B)  Reduce the percentage in principal amount of the Senior Debt Securities
         of the affected series, the consent of whose Holders is required for
         any such modification or for any waiver provided for in the Senior Debt
         Indenture.

    Prior to the acceleration of the maturity of any Senior Debt Security, the
Holders (voting as one class) of a majority in aggregate principal amount of the
Senior Debt Securities of all series at the time Outstanding with respect to
which a default or an Event of Default shall have occurred and be continuing may
on behalf of the Holders of all such affected Senior Debt Securities waive any
past default or Event of Default and its consequences, except a default or an
Event of Default in respect of a covenant or provision of the Senior Debt
Indenture or of any Senior Debt Security which cannot be modified or amended
without the consent of the Holder of each Senior Debt Security affected.

    Defeasance, Covenant Defeasance and Discharge. The Senior Debt Indenture
provides that, at the option of CMS Energy: (a) CMS Energy will be discharged
from any and all obligations in respect of the Senior Debt Securities of a
particular series then Outstanding (except for certain obligations to register
the transfer of or exchange the Senior Debt Securities of such series, to
replace stolen, lost or mutilated Senior Debt Securities of such series, to
maintain paying agencies and to maintain the trust described below); or (b) CMS
Energy need not comply with certain restrictive covenants of the Senior Debt
Indenture (including those described under "Consolidation, Merger or Sale of
Assets"), in each case if CMS Energy irrevocably deposits in trust with the
Senior Debt Trustee money, and/or securities backed by the full faith and credit
of the United States which, through the payment of the principal thereof and the
interest thereon in accordance with their terms, will provide money in an amount
sufficient to pay all the principal of and premium, if any, and interest on the
Senior Debt Securities of such series on the stated maturity of such Senior Debt
Securities (which may include one or more redemption dates designated by CMS
Energy) in accordance with the terms thereof. To exercise such option, CMS
Energy is required, among other things, to deliver to the Senior Debt Trustee an
opinion of independent counsel to the effect that the exercise of such option
would not cause the Holders of the Senior Debt Securities of such series to
recognize income, gain or loss for United States federal income tax purposes as
a result of such defeasance, and such Holders will be subject to United States
federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such defeasance had not occurred, and, in the
case of a discharge as described in clause (a) of the preceding sentence, such
opinion is to be accompanied by a private letter ruling to the same effect
received from the Internal Revenue Service, a revenue ruling to such effect
pertaining to a comparable form of transaction published by the Internal Revenue
Service or appropriate evidence that since the date of the Senior Debt Indenture
there has been a change in the applicable federal income tax law.

    In the event CMS Energy exercises its option to effect a covenant defeasance
with respect to the Senior Debt Securities of any series as described in the
preceding paragraph and the Senior Debt Securities of such series are thereafter
declared due and payable because of the occurrence of any Event of Default other
than an Event of Default caused by failing to comply with the covenants which
are defeased, and the amount of money and securities on deposit with the Senior
Debt Trustee would be insufficient to pay amounts due on the Senior Debt
Securities of such series at the time of the acceleration resulting from such
Event of Default, CMS Energy would remain liable for such amounts.

    CMS Energy may also obtain a discharge of the Senior Debt Indenture with
respect to all Senior Debt Securities then Outstanding (except for certain
obligations to register the transfer of or exchange such Senior Debt Securities,
to replace stole, lost or mutilated Senior Debt Securities, to maintain paying
agencies and to maintain the trust described below) by irrevocably depositing in
trust with the Senior Debt Trustee money, and/or securities backed by the full
faith and credit of the United States which, through the payment of the
principal



                                       8
<PAGE>   12

thereof and the interest thereon in accordance with their terms, will provide
money in an amount sufficient to pay all the principal of and premium, if any,
and interest on the Senior Debt Securities on the stated maturities thereof
(including one or more redemption dates), provided that such Senior Debt
Securities are by their terms due and payable, or are to be called for
redemption, within one year.

    For United States federal income tax purposes any deposit contemplated in
the preceding paragraph would be treated as an exchange of the Senior Debt
Securities outstanding for other property. Accordingly, Holders of Senior Debt
Securities outstanding may be required to recognize a gain or loss for United
States federal income tax purposes upon such exchange. In addition, such Holders
thereafter may be required to recognize income from such property which could be
different from the amount that would be includable in the absence of such
deposit. Prospective investors are urged to consult their own tax advisors as to
the specific consequences to them of such deposit.

    Governing Law. The Senior Debt Indenture and Senior Debt Securities will be
governed by, and construed in accordance with, the laws of the State of Michigan
unless the laws of another jurisdiction shall mandatorily apply.

SUBORDINATED DEBT SECURITIES

    General. The Subordinated Debt Securities will be issuable under the
Subordinated Debt Indenture. The Subordinated Debt Indenture does not limit the
aggregate principal amount of Subordinated Debt Securities which may be issued
thereunder. Subordinated Debt Securities may be issued under the Subordinated
Debt Indenture from time to time in one or more series. The Subordinated Debt
Securities shall mature on a date not less than nine months nor more than 40
years after the date of issuance. Capitalized terms used in this section
"Subordinated Debt Securities" and not otherwise specifically defined in this
prospectus shall have the meanings respectively set forth in the Subordinated
Debt Indenture.

    Exchange and Transfer. Subordinated Debt Securities may be presented for
exchange and registered Subordinated Debt Securities may be presented for
registration of transfer at the offices and subject to the restrictions set
forth therein and in the applicable prospectus supplement without service
charge, but upon payment of any taxes or other governmental charges due in
connection therewith, subject to any applicable limitations contained in the
Subordinated Debt Indenture. Subordinated Debt Securities in bearer form and the
coupons appertaining thereto, if any, will be transferable by delivery.

    Payment. Unless otherwise indicated in the applicable prospectus supplement,
payment of the principal of and the premium and interest, if any, on all
Subordinated Debt Securities in registered form will be made at the office or
agency of the Subordinated Debt Trustee in the City of New York, except that, at
the option of CMS Energy, payment of any interest may be made (i) by check
mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register or (ii) by wire transfer to an account
maintained by the Person entitled thereto as specified in the Security Register.
Unless otherwise indicated in the applicable prospectus supplement, payment of
any interest due on Subordinated Debt Securities in registered form will be made
to the Persons in whose name such Subordinated Debt Securities are registered at
the close of business on the Record Date for such interest payments.

    Events of Default. The occurrence of any of the following events with
respect to the Subordinated Debt Securities of any series will constitute an
"Event of Default" with respect to the Subordinated Debt Securities of such
series:

    (A)  Default for 30 days in the payment of any interest on any of the
         Subordinated Debt Securities of such series (whether or not payment is
         prohibited by the subordination provisions of the Subordinated Debt
         Indenture); provided, however, that if CMS Energy is permitted by the
         terms of the Subordinated Debt Securities of the applicable series to
         defer the payment in question, the date on which such payment is due
         and payable shall be the date on which CMS Energy is required to make
         payment following such deferral, if such deferral has been elected
         pursuant to the terms of the Subordinated Debt Securities;

    (B)  Default in the payment when due of any of the principal of or the
         premium, if any, on any of the Subordinated Debt Securities of such
         series, whether at maturity, upon redemption, acceleration or otherwise
         (whether or not payment is prohibited by the subordination provision of
         the Subordinated Debt Indenture); provided, however, that if CMS Energy
         is permitted by the terms of the Subordinated Debt Securities of the
         applicable series to defer the payment in question, 

                                       9
<PAGE>   13


         the date on which such payment is due and payable shall be the date on
         which CMS Energy is required to make payment following such deferral,
         if such deferral has been elected pursuant to the terms of the
         Subordinated Debt Securities;

    (C)  Default in the deposit or payment of any sinking fund or analogous
         payment in respect if any Subordinated Debt Securities of such series
         (whether or not payment is prohibited by the subordination provisions
         of the Subordinated Debt Indenture);

    (D)  Default for 60 days by CMS Energy in the observance or performance of
         any other covenant or agreement contained in the Subordinated Debt
         Indenture relating to the Subordinated Debt Securities of such series
         after written notice thereof as provided in the Subordinated Debt
         Indenture;

    (E)  Certain events of bankruptcy, insolvency or reorganization relating to
         CMS Energy;

    (F)  Entry of final judgments against CMS Energy or Consumers Energy
         aggregating in excess of $25,000,000 which remain undischarged or
         unbonded for 60 days; or

    (G)  A default resulting in the acceleration of indebtedness of CMS Energy
         in excess of $25,000,000 which acceleration has not been rescinded or
         annulled within 10 days after written notice of such default as
         provided in the Subordinated Debt Indenture.

    Additional Events of Default may be prescribed for the benefit of the
Holders of a particular series of Subordinated Debt Securities and will be
described in the prospectus supplement relating to such Subordinated Debt
Securities.

    If any Event of Default on any series of Subordinated Debt Securities shall
have occurred and be continuing, either the Subordinated Debt Trustee or the
Holders of not less than 25% in aggregate principal amount of the Subordinated
Debt Securities of such series then Outstanding may declare the principal of all
Subordinated Debt Securities of such series and the interest, if any, accrued
thereon to be due and payable immediately.

    Upon certain conditions, any such declarations may be rescinded and annulled
if all Events of Default, other than the nonpayment of accelerated principal,
with respect to the Subordinated Debt Securities of all such affected series
then Outstanding shall have been cured or waived as provided in the Subordinated
Debt Indenture by the Holders of a majority in aggregate principal amount of the
Subordinated Debt Securities of the affected series then Outstanding.

    Reference is made to the prospectus supplement relating to any series of
Original Issue Discount Securities for the particular provisions relating to the
acceleration of a portion of the principal amount thereof upon the occurrence
and continuance of an Event of Default with respect thereto.

    The Subordinated Debt Indenture provides that the Subordinated Debt Trustee
will be under no obligation to exercise any of its rights or powers under the
Subordinated Debt Indenture at the request, order or direction of the Holders of
the Subordinated Debt Securities, unless such Holders shall have offered to the
Subordinated Debt Trustee reasonable indemnity. Subject to such provisions for
indemnity and certain other limitations contained in the Subordinated Debt
Indenture, the Holders of a majority in aggregate principal amount of the
Subordinated Debt Securities of each affected series then Outstanding (voting as
one class) will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Subordinated Debt
Trustee, or exercising any trust or power conferred on the Subordinated Debt
Trustee, with respect to the Subordinated Debt Securities of such affected
series.

    The Subordinated Debt Indenture provides that no Holder of Subordinated Debt
Securities may institute any action against CMS Energy under the Subordinated
Debt Indenture (except actions for payment of overdue principal, premium or
interest) unless such Holder previously shall have given to the Subordinated
Debt Trustee written notice of default and continuance thereof and unless the
Holders of not less than 25% in aggregate principal amount of the Subordinated
Debt Securities of the affected series then Outstanding (voting as one class)
shall have requested the Subordinated Debt Trustee to institute such action and
shall have offered the Subordinated Debt Trustee 




                                       10
<PAGE>   14

reasonable indemnity, the Subordinated Debt Trustee shall not have received
direction inconsistent with such request by the Holders of a majority in
aggregate principal amount of the Subordinated Debt Securities of the affected
series then Outstanding (voting as one class).

    The Subordinated Debt Indenture requires CMS Energy to furnish to the
Subordinated Debt Trustee annually a statement as to CMS Energy?s compliance
with all conditions and covenants under the Subordinated Debt Indenture. The
Subordinated Debt Indenture provides that the Subordinated Debt Trustee may
withhold notice to the Holders of the Subordinated Debt Securities of any series
of any default affecting such series (except defaults as to payment of
principal, premium or interest on the Subordinated Debt Securities of such
series) if it considers such withholding to be in the interests of the Holders
of the Subordinated Debt Securities of such series.

    Subordination. The Subordinated Debt Indenture provides (and each Holder of
Subordinated Debt Securities by acceptance thereof agrees) that the Subordinated
Debt Securities will be subordinated in right of payment to the prior payment in
full of all Senior Indebtedness (as defined herein) of CMS Energy. No payment on
account of principal of, premium, if any, or interest on the Subordinated Debt
Securities and no acquisition of, or payment on account of any sinking fund for,
the Subordinated Debt Securities may be made unless full payment of amounts then
due for principal, premium, if any, and interest then due on all Senior
Indebtedness by reason of the maturity thereof (by lapse of time, acceleration
or otherwise) has been made or duly provided for in cash or in a manner
satisfactory to the Holders of such Senior Indebtedness. In addition, the
Subordinated Debt Indenture provides that upon the happening and during the
continuation of any default in payment of the principal of, premium, if any, or
interest on any Senior Indebtedness when the same becomes due and payable or in
the event any judicial proceeding shall be pending with respect to any such
default, then, unless and until such default shall have been cured or waived or
shall have ceased to exist, no payment shall be made by CMS Energy with respect
to the principal of, premium, if any, or interest on Subordinated Debt
Securities or to acquire any Subordinated Debt Securities or on account of any
sinking fund provisions applicable to Subordinated Debt Securities. CMS Energy
shall give prompt written notice to the Subordinated Debt Trustee of any default
in payment of principal of or interest on any Senior Indebtedness. The
Subordinated Debt Indenture provisions described in this paragraph, however, do
not prevent CMS Energy from making sinking fund payments in Subordinated Debt
Securities acquired prior to the maturity of Senior Indebtedness or, in the case
of default, prior to such default and notice thereof. Upon any distribution of
its assets in connection with any dissolution, winding up, liquidation or
reorganization of CMS Energy, whether voluntary or involuntary, in bankruptcy,
insolvency or receivership proceedings or upon an assignment for the benefit of
creditors or otherwise: (i) all Senior Indebtedness must be paid in full before
the Holders of the Subordinated Debt Securities are entitled to any payments
whatsoever; and (ii) any payment or distribution of CMS Energy?s assets of any
kind or character, whether in cash, securities or other property, which would
otherwise (but for the subordination provisions) be payable or deliverable in
respect of the Subordinated Debt Securities shall be paid or delivered directly
to the Holders of such Senior Indebtedness (or their representative or trustee)
in accordance with the priorities then existing among such Holders until all
Senior Indebtedness shall have been paid in full before any payment or
distribution is made to the Holders of Subordinated Debt Securities. In the
event that notwithstanding such subordination provisions, any payment or
distribution of assets of any kind or character is made on the Subordinated Debt
Securities before all Senior Indebtedness is paid in full, the Subordinated Debt
Trustee or the Holders of Subordinated Debt Securities receiving such payment
will be required to pay over such payment or distribution to the Holders of such
Senior Indebtedness. Subject to the payment in full of all Senior Indebtedness,
the rights of the Holders of the Subordinated Debt Securities will be subrogated
to the rights of the Holders of Senior Indebtedness to receive payments or
distributions applicable to Senior Indebtedness until all amounts owing on the
Subordinated Debt Securities are paid in full. As a result of the subordination
provisions, in the event of CMS Energy?s insolvency, Holders of the Subordinated
Debt Securities may recover ratably less than senior creditors of CMS Energy.

    "Senior Indebtedness" means the principal of and premium, if any, and
interest on the following, whether outstanding on the date of execution of the
Subordinated Debt Indenture or thereafter incurred, created or assumed:

    (I)   Indebtedness of CMS Energy for money borrowed by CMS Energy (including
          purchase money obligations) or evidenced by debentures (other than the
          Subordinated Debt Securities), notes, bankers? acceptances or other
          corporate debt securities or similar instruments issued by CMS Energy;

    (II)  Obligations with respect to letters of credit;

    (III) All Indebtedness of others of the type referred to in the preceding
          clauses (I) and (II) assumed by or guaranteed in any manner by CMS
          Energy or in effect guaranteed by CMS Energy; or



                                       11
<PAGE>   15

    (IV)  Renewals, extensions or refundings of any of the indebtedness referred
          to in the preceding clauses (I), (II) and (III) unless, in the case of
          any particular indebtedness, renewal, extension or refunding, under
          the express provisions of the instrument creating or evidencing the
          same or the assumption or guarantee of the same, or pursuant to which
          the same is outstanding, such indebtedness or such renewal, extension
          or refunding thereof is not superior in right of payment to the
          Subordinated Debt Securities.

    The Subordinated Debt Indenture does not limit the aggregate amount of
Senior Indebtedness that may be issued. As of September 30, 1998, Senior
Indebtedness of CMS Energy aggregated approximately $2,321 million.

    Consolidation, Merger or Sale of Assets. The Subordinated Debt Indenture
provides that CMS Energy may consolidate with or merge into, or sell, lease or
convey its property as an entirety or substantially as an entirety to, any other
corporation if such corporation assumes the obligations of CMS Energy under the
Subordinated Debt Securities and the Subordinated Debt Indenture and is
organized and existing under the laws of the United States of America, any state
thereof or the District of Columbia.

    Modification of the Subordinated Debt Indenture. The Subordinated Debt
Indenture permits CMS Energy and the Subordinated Debt Trustee to enter into
supplemental indentures thereto without the consent of the Holders of the
Subordinated Debt Securities to:

    (A)  Secure the Subordinated Debt Securities of one or more series;

    (B)  Evidence the assumption by a successor corporation of the obligations
         of CMS Energy under the Subordinated Debt Indenture and the
         Subordinated Debt Securities then Outstanding;

    (C)  Add covenants for the protection of the Holders of the Subordinated
         Debt Securities;

    (D)  Cure any ambiguity or correct any defect or inconsistency in the
         Subordinated Debt Indenture or to make such other provisions as CMS
         Energy deems necessary or desirable with respect to matters or
         questions arising under the Subordinated Debt Indenture, provided that
         no such action adversely affects the interests of any Holders of
         Subordinated Debt Securities;

    (E)  Establish the form and terms of any series of securities under the
         Subordinated Debt Indenture; and

    (F)  Evidence the acceptance of appointment by a successor Subordinated Debt
         Trustee.

    The Subordinated Debt Indenture also permits CMS Energy and the Subordinated
Debt Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Subordinated Debt Securities of all series
then Outstanding and affected (voting as one class), to enter into supplemental
indentures to add any provisions to, or change in any manner or eliminate any of
the provisions of, the Subordinated Debt Indenture or modify in any manner the
rights of the Holders of Subordinated Debt Securities of each such affected
series; provided, however, that CMS Energy and the Subordinated Debt Trustee may
not, without the consent of the Holder of each Subordinated Debt Security then
outstanding and affected thereby, enter into a supplemental indenture to:

    (A)  Change the time of payment of the principal (or any installment of
         principal) of any Subordinated Debt Security, or reduce the principal
         amount thereof, or reduce the rate or change the time of payment of
         interest thereon, or reduce the amount payable on any Original Issue
         Discount Securities upon acceleration or provable in bankruptcy, or
         impair the right to institute suit for the enforcement of any payment
         on any Subordinated Debt Security when due; or

    (B)  Reduce the percentage in principal amount of the Subordinated Debt
         Securities of the affected series, the consent of whose Holders is
         required for any such modification or for any waiver provided for in
         the Subordinated Debt Indenture.

    Prior to the acceleration of the maturity of any Subordinated Debt Security,
the Holders of a majority in aggregate principal amount of the Subordinated Debt
Securities of all series at the time Outstanding with respect to which a default
or an Event of Default shall have occurred and be continuing (voting as one
class) may on behalf of the Holders of all such affected Subordinated Debt
Securities waive any past default or Event of Default and its consequences,
except a default or an Event of Default in respect of a covenant or provision of
the Subordinated Debt Indenture or of any Subordinated Debt Security which
cannot be modified or amended without the consent of the Holder of each
Subordinated Debt Security affected.

    Defeasance, Covenant Defeasance and Discharge. The Subordinated Debt
Indenture provides that, at the option of CMS Energy:

    (A)  CMS Energy will be discharged from any and all obligations in respect
         of the Subordinated Debt Securities of a particular series then
         Outstanding (except for certain obligations to register the transfer of
         or exchange the Subordinated Debt Securities of such series, to replace
         stolen, lost or mutilated Subordinated Debt Securities of such series,
         to maintain paying agencies and to maintain the trust described below),
         or



                                       13
<PAGE>   17

    (B)  CMS Energy need not comply with certain restrictive covenants of the
         Subordinated Debt Indenture (including those described under
         "Consolidation, Merger or Sale of Assets"), in each case if CMS Energy
         irrevocably deposits in trust with the Subordinated Debt Trustee money,
         and/or securities backed by the full faith and credit of the United
         States which, through payment of the principal thereof and the interest
         thereon in accordance with their terms, will provide money in an amount
         sufficient to pay all the principal of and premium, if any, and
         interest on the Subordinated Debt Securities of such series on the
         stated maturity of such Subordinated Debt Securities (which may include
         one or more redemption dates designated by CMS Energy) in accordance
         with the terms thereof.

    To exercise such option, CMS Energy is required, among other things, to
deliver to the Subordinated Debt Trustee an opinion of independent counsel to
the effect that the exercise of such option would not cause the Holders of the
Subordinated Debt Securities of such series to recognize income, gain or loss
for United States federal income tax purposes as amounts, in the same manner and
at the same times as would have been the case if such defeasance had not
occurred, and, in the case of a discharge as described in clause (A) of the
preceding paragraph, such opinion is to be accompanied by a private letter
ruling to the same effect received from the Internal Revenue Service, a revenue
ruling to such effect pertaining to a comparable form of transaction published
by the Internal Revenue Service or appropriate evidence that since the date of
the Subordinated Debt Indenture there has been a change in the applicable
federal income tax law.

    In the event CMS Energy exercises its option to effect a covenant defeasance
with respect to the Subordinated Debt Securities of any series as described in
the preceding paragraph and the Subordinated Debt Securities of such series are
thereafter declared due and payable because of the occurrence of any Event of
Default other than an Event of Default caused by failing to comply with the
covenants which are defeased, and the amount of money and securities on deposit
with the Subordinated Debt Trustee would be insufficient to pay amounts due on
the Subordinated Debt Securities of such series at the time of the acceleration
resulting from such Event of Default, CMS Energy would remain liable for such
amounts.

    CMS Energy may also obtain a discharge of the Subordinated Debt Indenture
with respect to all Subordinated Debt Securities then Outstanding (except for
certain obligations to register the transfer of or exchange such Subordinated
Debt Securities to replace stolen, lost or mutilated Subordinated Debt
Securities, to maintain paying agencies and to maintain the trust described
below) by irrevocably depositing in trust with the Subordinated Debt Trustee
money, and/or securities backed by the full faith and credit of the United
States which, through the payment of the principal thereof and the interest
thereon in accordance with their terms, will provide money in an amount
sufficient to pay all the principal of and premium, if any, and interest on the
Subordinated Debt Securities on the stated maturities thereof (including one or
more redemption dates), provided that such Subordinated Debt Securities are by
their terms due and payable, or are to be called for redemption, within one
year.

    For United States federal income tax purposes any deposit contemplated in
the preceding paragraph would be treated as an exchange of the Subordinated Debt
Securities outstanding for other property. Accordingly, holders of Subordinated
Debt Securities outstanding may be required to recognize a gain or loss for
United States federal income tax purposes upon such exchange. In addition, such
Holders thereafter may be required to recognize income from such property which
could be different from the amount that would be includable in the absence of
such deposit. Prospective investors are urged to consult their own tax advisors
as to the specific consequences to them of such deposit.

    Governing Law. The Subordinated Debt Indenture and the Subordinated Debt
Securities will be governed by, and construed in accordance with, the laws of
the State of Michigan except to the extent the laws of another jurisdiction
shall be mandatorily applicable.

                                 LEGAL OPINIONS

    Opinions as to the legality of certain of the Offered Securities will be
rendered for CMS Energy by Michael D. Van Hemert, Esq., Assistant General
Counsel for CMS Energy. Certain legal matters with respect to Offered Securities
will be passed upon by counsel for any underwriters, dealers or agents, each of
whom will be named in the related prospectus supplement.

                                     EXPERTS


    The consolidated financial statements and schedule of CMS Energy as of
December 31, 1997 and 1996, and for each of the three years in the period ended
December 31, 1997 incorporated by reference in this prospectus, have been
audited by Arthur Andersen LLP, independent public accountants, as indicated in
their reports with respect thereto, and are included herein in reliance upon the
authority of said firm as experts in accounting and auditing in giving said
reports.

    With respect to the unaudited interim consolidated financial information for
the periods ended March 31, 1998 and 1997, June 30, 1998 and 1997, and September
30, 1998 and 1997, Arthur Andersen LLP has applied limited procedures in
accordance with professional standards for a review of such information.
However, their separate reports thereon state that they did not audit and they
did not express an opinion on that interim consolidated financial information.
Accordingly, the degree of reliance on their report on that information should
be restricted in light of the limited nature of the review procedures applied.
In addition, the accountants are not subject to the liability provisions of
Section 11 of the Securities Act, for their reports on the unaudited interim
consolidated financial information because those reports are not a "report" or
"part" of the registration statement prepared or certified by the accountants
within the meaning of Sections 7 and 11 of the Securities Act.

    Future consolidated financial statements of CMS Energy and the reports
thereon of Arthur Andersen LLP also will be incorporated by reference in this
prospectus in reliance upon the authority of that firm as experts in giving
those reports to the extent that said firm has audited said consolidated
financial statements and consented to the use of their reports thereon.



                              PLAN OF DISTRIBUTION

    CMS Energy may sell the Offered Securities: (i) through the solicitation of
proposals of underwriters or dealers to purchase the Offered Securities; (ii)
through underwriters or dealers on a negotiated basis; (iii) directly to a
limited number of purchasers or to a single purchaser; or (iv) through agents.
The prospectus supplement with respect to any Offered Securities will set forth
the terms of such offering, including the name or names of any underwriters,
dealers or agents; the purchase price of the Offered Securities and the proceeds
to CMS Energy from such sale; any underwriting discounts and commissions and
other items constituting underwriters' compensation; any initial public offering
price and any discounts or concessions allowed or reallowed or paid to dealers
and any securities exchange on which such Offered Securities may be listed. Any
initial public offering price, discounts or concessions allowed or reallowed or
paid to dealers may be changed from time to time.

    If underwriters are used in the sale, the Offered Securities will be
acquired by the underwriters for their own account and may be resold from time
to time in one or more transactions, including negotiated transactions, at a
fixed public offering price or at varying prices determined at the time of sale.
The Offered Securities may be offered to the public either through underwriting
syndicates represented by one or more managing underwriters or directly by one
or more firms acting as underwriters. The underwriter or underwriters with
respect to a particular underwritten offering of Offered Securities will be
named in the prospectus supplement relating to such offering and, if an
underwriting syndicate is used, the managing underwriter or underwriters will be
set forth on the cover of such prospectus supplement. Unless otherwise set forth
in the prospectus supplement relating thereto, the obligations of the
underwriters to purchase the Offered Securities will be subject to certain
conditions precedent, and the underwriters will be obligated to purchase all the
Offered Securities if any are purchased.

If dealers are utilized in the sale of Offered Securities, CMS Energy will sell
such Offered Securities to the dealers as principals. The dealers may then
resell such Offered Securities to the public at varying prices to be determined
by such dealers at the time of resale. The names of the dealers and the terms of
the transaction will be set forth in the prospectus supplement relating thereto.

    The Offered Securities may be sold directly by CMS Energy or through agents
designated by CMS Energy from time to time. Any agent involved in the offer or
sale of the Offered Securities in respect to which this prospectus is delivered
will be named, and any commissions payable by CMS Energy to such agent will be
set forth, in the prospectus supplement relating thereto. Unless otherwise
indicated in the prospectus supplement, any such agent will be acting on a best
efforts basis for the period of its appointment.


                                       16
<PAGE>   20


    The Offered Securities may be sold directly by CMS Energy to institutional
investors or others, who may be deemed to be underwriters within the meaning of
the Securities Act with respect to any resale thereof. The terms of any such
sales will be described in the prospectus supplement relating thereto.

    Agents, dealers and underwriters may be entitled under agreements with CMS
Energy to indemnification by CMS Energy against certain civil liabilities,
including liabilities under the Securities Act, or to contribution with respect
to payments which such agents, dealers or underwriters may be required to make
in respect thereof. Agents, dealers and underwriters may be customers of, engage
in transactions with, or perform services for CMS Energy in the ordinary course
of business.

    The Offered Securities may or may not be listed on a national securities
exchange. Reference is made to the prospectus supplement with regard to such
matter. No assurance can be given that there will be a market for any of the
Offered Securities.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The following resolution was adopted by the Board of Directors of CMS Energy
on May 6, 1987:

    Resolved: That effective March 1, 1987 the corporation shall indemnify to
the full extent permitted by law every person (including the estate, heirs and
legal representatives of such person in the event of the decease, incompetency,
insolvency or bankruptcy of such person) who is or was a director, officer,
partner, trustee, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, partner, trustee,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against all liability, costs, expenses, including attorneys'
fees, judgments, penalties, fines and amounts paid in settlement, incurred by or
imposed upon the person in connection with or resulting from any claim or any
threatened, pending or completed action, suit or proceeding whether civil,
criminal, administrative, investigative or of whatever nature, arising from the
person's service or capacity as, or by reason of the fact that the person is or
was, a director, officer, partner, trustee, employee or agent of the Corporation
or is or was serving at the request of the Corporation as a director, officer,
partner, trustee, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise. Such right of indemnification shall not be
deemed exclusive of any other rights to which the person may be entitled under
statute, bylaw, agreement, vote of shareholders or otherwise.

CMS Energy's Bylaws provide:

    The Corporation may purchase and maintain liability insurance, to the full
extent permitted by law, on behalf of any person who is or was a director,
officer, employee or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against any
liability asserted against such person and incurred by such person in any such
capacity.

Article VIII of CMS Energy's Articles of Incorporation provides:

    A director shall not be personally liable to the Corporation or its
shareholders for monetary damages for breach of duty as a director except (I)
for a breach of the director's duty of loyalty to the Corporation or its
shareholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) for a violation of
section 551 (I) of the Michigan Business Corporation Act, and (iv) any action
from which the director derived an improper personal benefit. No amendment to or
repeal of this Article VIII, and no modification to its provisions by law, shall
apply to, or have any effect upon,

                                      II-1
<PAGE>   22

the liability or alleged liability of any director of the Corporation for or
with respect to any acts or omissions of such director occurring prior to such
amendment, repeal or modification.

Article IX of CMS Energy's Articles of Incorporation provides:

    Each director and each officer of the Corporation shall be indemnified by
the Corporation to the fullest extent permitted by law against expenses
(including attorneys' fees), judgments, penalties, fines and amounts paid in
settlement actually and reasonably incurred by him or her in connection with the
defense of any proceeding in which he or she was or is a party or is threatened
to be made a party by reason of being or having been a director or an officer of
the Corporation. Such right of indemnification is not exclusive of any other
rights to which such director or officer may be entitled under any now or
thereafter existing statute, any other provision of these Articles, bylaw,
agreement, vote of shareholders or otherwise. If the Business Corporation Act of
the State of Michigan is amended after approval by the shareholders of this
article IX to authorize corporate action further eliminating or limiting the
personal liability of directors, then the liability of a director of the
Corporation shall be eliminated or limited to the fullest extent permitted by
the Business Corporation Act of the State of Michigan, as so amended. Any repeal
or modification of this article IX by the shareholders of the Corporation shall
not adversely affect any right or protection of a director of the Corporation
existing at the time of such repeal or modification.

    Sections 561 through 571 of the Michigan Business Corporation Act provides
CMS Energy with the power to indemnify directors, officers, employees and agents
against certain expenses and payments, and to purchase and maintain insurance on
behalf of directors, officers, employees and agents.

    Officers and directors are covered within specified monetary limits by
insurance against certain losses arising from claims made by reason of their
being directors or officers of CMS Energy or of CMS Energy's subsidiaries and
CMS Energy's officers and directors are indemnified against such losses by
reason of their being or having been directors of officers or another
corporation, partnership, joint venture, trust or other enterprise at CMS
Energy's request. In addition, CMS Energy has indemnified each of its present
directors by contracts that contain affirmative provisions essentially similar
to those in sections 561 through 571 of the Michigan Business Corporation Act
cited above.

ITEM 17. UNDERTAKINGS.

    The undersigned registrants hereby undertake:

    (1) To file a post-effective amendment to this registration statement  
during any period in which offers or sales are being made:

        (i)    Include any prospectus required by Section 10(a)(3) of the
               Securities Act of 1933;

        (ii)   Reflect in the prospectus any facts or events arising after
               the effective date of the registration statement (or the
               most recent post-effective amendment thereof) which,
               individually or in the aggregate, represent a fundamental
               change in the information set forth in the registration
               statement. Notwithstanding the foregoing, any increase or
               decrease in volume of securities offered (if the total
               dollar value of securities offered would not exceed that
               which was registered) and any deviation from the low or
               high end of the estimated maximum offering range may be
               reflected in the form of prospectus filed with the
               Commission pursuant to Rule 424(b) if, in the aggregate,
               the changes in volume and price represent no more than a
               20% change in the maximum aggregate offering price set
               forth in the "Calculation of Registration Fee" table in the
               effective registration statement;

        (iii)  Include any material information with respect to the plan
               of distribution not previously disclosed in the
               registration statement or any material change to such
               information in the registration statement; provided,
               however, that (i) and (ii) do not apply if the registration
               statement is on Form S-3 or Form S-8, and the information
               required to be included in a post-effective amendment by
               those paragraphs is contained in periodic reports filed
               with or furnished to the Commission by the registrant
               pursuant to Section 13 or Section 15(d) of the Securities
               Exchange Act of 1934 that are incorporated by reference in
               the registration statement.

    (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

    (3) To remove from registration by means of post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

    (4) That, for purposes of determining any liability under the Securities Act
of 1933, each filing of the registrant's annual report pursuant to section 13(a)
or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by
reference in this registration statement shall be deemed to be a new
registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

    (5) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions described under Item 15 above, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that as
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
be governed by the final adjudication of such issue.

    (6) That (1) for purposes of determining any liability under the Securities
Act of 1933, the information omitted from the form of prospectus filed as part
of this Registration Statement in reliance upon Rule 430A and contained in a
form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective; and (2) for the purpose of
determining any liability under the Securities Act of 1933, each post-


                                      II-6

effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

To the Representatives named
in Schedule I hereto of the
Underwriters named in
Schedule II hereto

Dear Sirs:

          CMS Energy Corporation, a Michigan corporation (the "Company"),
proposes to issue and sell to the several Underwriters (as defined in Section 14
hereof) ________ shares of its Common Stock ($.01 par value) (the "Securities")
as indicated in Schedule II. The Underwriters have designated the
Representatives to execute this Agreement on their behalf and to act for them in
the manner provided in this Agreement.

          The Company has prepared and filed with the Securities and Exchange
Commission (the "Commission"), in accordance with the provisions of the
Securities Act of 1933, as amended (the "Act"), a registration statement on Form
S-3 (Registration No. ___________) including a prospectus relating to the
Securities, and such registration statement, has become effective under the Act.
The registration statement, at the time such registration statement, became
effective and as it may have been thereafter amended to the date of this
Agreement (including the documents then incorporated by reference therein) is
hereinafter referred to as the "Registration Statement." If the Company has
filed, or will file, an breviated registration statement to register additional
Securities pursuant to Rule 462(b) under the Act (the "Rule 462(b) Registration
Statement"), then any reference herein to the term "Registration Statement"
shall be deemed to include such Rule 462(b) Registration Statement. The
prospectus forming a part of the Registration Statement at the time the
Registration Statement became effective (including the documents then
incorporated by reference therein) is hereinafter referred to as the "Basic
Prospectus," provided that in the event that the Basic Prospectus shall have
been

amended, revised or supplemented prior to the date of this Agreement, or if
the Company shall have supplemented the Basic Prospectus by filing any documents
pursuant to Section 13 or 14 or 15 of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), after the time the Registration Statement became
effective and prior to the date of this Agreement, which documents are deemed to
be incorporated in the Basic Prospectus, the term "Basic Prospectus" shall also
mean such prospectus as so amended, revised or supplemented. The Basic
Prospectus, as it shall be revised or supplemented to reflect the final terms of
the offering and sale of the Securities by a prospectus supplement relating to
the Securities, and in the form to be filed with, or transmitted for filing to,
the Commission pursuant to Rule 424 under the Act, is hereinafter referred to as
the "Prospectus." Any reference herein to the terms "amend," "amendment" or
"supplement" with respect to the Registration Statement or the Prospectus shall
be deemed to include only amendments or supplements to the Registration
Statement or Prospectus, as the case may be, and documents incorporated by
reference therein after the date of this Agreement and prior to the termination
of the offering of the Securities by the Underwriters.


     1.   Purchase and Sale: Upon the basis of the representations and
warranties and on the terms and subject to the conditions herein set forth, the

to the Company for use in the Registration Statement and Prospectus, the
information stated herein with regard to the public offering, if any, by such
Underwriter and represents and warrants that such information is correct in all
material respects as to such Underwriter.

     8.   Indemnification:

          (a)     The Company agrees, to the extent permitted by law, to
     indemnify and hold harmless each of the Underwriters and each person, if
     any, who controls any such Underwriter within the meaning of Section 15 of
     the Act or Section 20 of the Exchange Act, against any and all losses,
     claims, damages or liabilities, joint or several, to which they or any of
     them may become subject under the Act or otherwise, and to reimburse the
     Underwriters and such controlling person or persons, if any, for any legal
     or other expenses incurred by them in connection with defending any action,
     suit or proceeding (including governmental investigations) as provided in
     Section 8(c) hereof, insofar as such losses, claims, damages, liabilities
     or actions, suits or proceedings (including governmental investigations)
     arise out of or are based upon any untrue statement or alleged untrue
     statement of a material fact contained in the Registration Statement, any
     preliminary prospectus as of its issue date (if used prior to the date of
     the Basic Prospectus), the Basic Prospectus (if used prior to the date of
     the Prospectus), the Prospectus, or, if the Prospectus shall be amended or
     supplemented, in the Prospectus as so amended or supplemented (if such
     Prospectus or such Prospectus as amended or supplemented is used after the
     period of time referred to in Section 5(e) hereof, it shall contain or be
     used with such amendments or supplements as the Company deems necessary to
     comply with Section 10(a) of the Act), or arise out of or are based upon
     any omission or alleged omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading, except insofar as such losses, claims, damages, liabilities or
     actions arise out of or are based upon any such untrue statement or alleged
     untrue statement or omission or alleged omission which was made in such
     preliminary Prospectus, Basic Prospectus, Registration Statement or
     Prospectus, or in the Prospectus as so amended or supplemented, in reliance
     upon and in conformity with information furnished in writing to the Company
     by, or through the Representatives on behalf of, any Underwriter expressly
     for use therein, and except that this indemnity shall not inure to the
     benefit of any Underwriter (or any person controlling such Underwriter) on
     account of


                                       11

<PAGE>   12

     any losses, claims, damages, liabilities or actions, suits or proceedings
     arising from the sale of the Securities to any person if a copy of the
     Prospectus, as the same may then be supplemented or amended (excluding,
     however, any document then incorporated or deemed incorporated therein by
     reference), was not sent or given by or on behalf of such Underwriter to
     such person (i) with or prior to the written confirmation of sale involved
     or (ii) as soon as available after such written confirmation, relating to
     an event occurring prior to the payment for and delivery to such person of
     the Securities involved in such sale, and the omission or alleged omission
     or untrue statement or alleged untrue statement was corrected in the
     Prospectus as supplemented or amended at such time.

          The Company's indemnity agreement contained in this Section 8(a), and
     the covenants, representations and warranties of the Company contained in
     this Agreement, shall remain in full force and effect regardless of any
     investigation made by or on behalf of any person, and shall survive the
     delivery of and payment for the Securities hereunder, and the indemnity
     agreement contained in this Section 8 shall survive any termination of this
     Agreement. The liabilities of the Company in this Section 8(a) are in
     addition to any other liabilities of the Company under this Agreement or
     otherwise.

          (b)     Each underwriter agrees, severally and not jointly, to the
     extent permitted by law, to indemnify, hold harmless and reimburse the
     Company, its directors and such of its officers as shall have signed the
     Registration Statement, each other Underwriter and each person, if any, who
     controls the Company or any such other Underwriter within the meaning of
     Section 15 of the Act or Section 20 of the Exchange Act, to the same extent
     and upon the same terms as the indemnity agreement of the Company set forth
     in Section 8(a) hereof, but only with respect to alleged untrue statements
     or omissions made in the Registration Statement, the Basic Prospectus or in
     the Prospectus, as amended or supplemented, (if applicable) in reliance
     upon and in conformity with information furnished in writing to the Company
     by such Underwriter expressly for use therein.

          The indemnity agreement on the part of each Underwriter contained in
this Section 8(b) and the representations and warranties of such Underwriter
contained in this Agreement shall remain in full force and effect regardless of
any investigation made by or on behalf of the Company or any other person, and
shall survive the delivery of and payment for the Securities hereunder, and the
indemnity agreement contained in this Section 8(b) shall survive any termination
of this Agreement. The liabilities of each Underwriter in Section 8(b) are in
addition to any other liabilities of such Underwriter under this Agreement or
otherwise.

          (c)     If a claim is made or an action, suit or proceeding (including
     governmental investigations) is commenced or threatened against any person
     as to which indemnity may be sought under Section 8(a) or 8(b), such person
     (the "Indemnified Person") shall notify the person against whom such
     indemnity may be sought (the "Indemnifying Person") promptly after any
     assertion of such claim threatening to institute an action, suit or
     proceeding or if such an action, suit or proceeding is commenced against
     such 


                                       12

<PAGE>   13

     Indemnified Person, promptly after such Indemnified Person shall have been
     served with a summons or other first legal process, giving information as
     to the nature and basis of the claim. Failure to so notify the Indemnifying
     Person shall not, however, relieve the Indemnifying Person from any
     liability which it may have on account of the indemnity under Section 8(a)
     or 8(b) if the Indemnifying Person has not been prejudiced in any material
     respect by such failure. Subject to the immediately succeeding sentence,
     the Indemnifying Person shall assume the defense of any such litigation or
     proceeding, including the employment of counsel and the payment of all
     expenses, with such counsel being designated, subject to the immediately
     succeeding sentence, in writing by the Representatives in the case of
     parties indemnified pursuant to Section 8(b) and by the Company in the case
     of parties indemnified pursuant to Section 8(a). Any Indemnified Person
     shall have the right to participate in such litigation or proceeding and to
     retain its own counsel, but the fees and expenses of such counsel shall be
     at the expense of such Indemnified Person unless (i) the Indemnifying
     Person and the Indemnified Person shall have mutually agreed to the
     retention of such counsel or (ii) the named parties to any such proceeding
     (including any impleaded parties) include (x) the Indemnifying Person and
     (y) the Indemnified Person and, in the written opinion of counsel to such
     Indemnified Person, representation of both parties by the same counsel
     would be inappropriate due to actual or likely conflicts of interest
     between them, in either of which cases the reasonable fees and expenses of
     counsel (including disbursements) for such Indemnified Person shall be
     reimbursed by the Indemnifying Person to the Indemnified Person. If there
     is a conflict as described in clause (ii) above, and the Indemnified
     Persons have participated in the litigation or proceeding utilizing
     separate counsel whose fees and expenses have been reimbursed by the
     Indemnifying Person and the Indemnified Persons, or any of them, are found
     to be solely liable, such Indemnified Persons shall repay to the
     Indemnifying Person such fees and expenses of such separate counsel as the
     Indemnifying Person shall have reimbursed. It is understood that the
     Indemnifying Person shall not, in connection with any litigation or
     proceeding or related litigation or proceedings in the same jurisdiction as
     to which the Indemnified Persons are entitled to such separate
     representation, be liable under this Agreement for the reasonable fees and
     out-of-pocket expenses of more than one separate firm (together with not
     more than one appropriate local counsel) for all such Indemnified Persons.
     Subject to the next paragraph, all such fees and expenses shall be
     reimbursed by payment to the Indemnified Persons of such reasonable fees
     and expenses of counsel promptly after payment thereof by the Indemnified
     Persons.

          In furtherance of the requirement above that fees and expenses of any
separate counsel of the Indemnified Persons shall be reasonable, the
Representatives and the Company agree that the Indemnifying Person's obligations
to pay such fees and expenses shall be conditioned upon the following:

               (1)    in case separate counsel is proposed to be retained by the
          Indemnified Persons pursuant to clause (ii) of the preceding
          paragraph, the Indemnified 


                                       13


<PAGE>   14


          Persons shall in good faith fully consult with the Indemnifying Person
          in advance as to the selection of such counsel; and

               (2)    reimbursable fees and expenses of such separate counsel
          shall be detailed and supported in a manner reasonably acceptable to
          the Indemnifying Person (but nothing herein shall be deemed to require
          the furnishing to the Indemnifying Person of any information,
          including without limitation, computer print-outs of lawyers' daily
          time entries, to the extent that, in the judgment of such counsel,
          furnishing such information might reasonably be expected to result in
          a waiver of any attorney-client privilege); and

               (3)    the Company and the Representatives shall cooperate in
          monitoring and controlling the fees and expenses of separate counsel
          for Indemnified Persons for which the Indemnifying Person is liable
          hereunder, and the Indemnified Person shall use every reasonable
          effort to cause such separate counsel to minimize the duplication of
          activities as between themselves and counsel to the Indemnifying
          Person.

          The Indemnifying Person shall not be liable for any settlement of any
litigation or proceeding effected without the written consent of the
Indemnifying Person, but if settled with such consent or if there be a final
judgment for the plaintiff, the Indemnifying Person agrees, subject to the
provisions of this Section 8, to indemnify the Indemnified Person from and
against any loss, damage, liability or expenses by reason of such settlement or
judgment. The Indemnifying Person shall not, without the prior written consent
of the Indemnified Persons, effect any settlement of any pending or threatened
litigation, proceeding or claim in respect of which indemnity has been properly
sought by the Indemnified Persons hereunder, unless such settlement includes an
unconditional release by the claimant of all Indemnified Persons from all
liability with respect to claims which are the subject matter of such
litigation, proceeding or claim.

     9.   Contribution: If the indemnification provided for in Section 8 above
is unavailable to or insufficient to hold harmless an Indemnified Person under
such Section in respect of any losses, claims, damages or liabilities (or
actions, suits or proceedings (including governmental investigations) in respect
thereof) referred to therein, then each Indemnifying Person under Section 8
shall contribute to the amount paid or payable by such Indemnified Person as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative benefits
received by the Indemnifying Person on the one hand and the Indemnified Person
on the other from the offering of the Securities. If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law, then each Indemnifying Person shall contribute to such amount paid or
payable by such Indemnified Person in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of each
Indemnifying Person, if any, on the one hand and the Indemnified Person on the
other in connection with the statements or omissions which resulted in such


                                       14

<PAGE>   15

losses, claims, damages or liabilities (or action, suits or proceedings
(including governmental investigations) in respect thereof), as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other shall be deemed to be
in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company and the total underwriting discounts
and commission received by the Underwriters, in each case as set forth in the
table on the cover page of the Prospectus, bear to the aggregate public offering
price of the Securities. The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or the Underwriters on the
other and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Underwriters agree that it would not be just and equitable if contribution
pursuant to this Section 9 were determined by pro rata allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other method
of allocation which does not take account of the equitable considerations
referred to above in this Section 9. The amount paid or payable by an
Indemnified Person as a result of the losses, claims, damages or liabilities (or
actions, suits or proceedings (including governmental proceedings) in respect
thereof) referred to above in this Section 9 shall be deemed to include any
legal or other expenses reasonably incurred by such Indemnified Person in
connection with investigating or defending any such action, suits or proceedings
(including governmental proceedings) or claim, provided that the provisions of
Section 8 have been complied with (in all material respects) in respect of any
separate counsel for such Indemnified Person. Notwithstanding the provisions of
this Section 9, no Underwriter shall be required to contribute any amount
greater than the excess of (i) the total price at which the Securities
underwritten by it and distributed to the public were offered to the public over
(ii) the amount of any damages which such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations in this Section 9 to contribute are several in
proportion to their respective underwriting obligations and not joint.

          The agreement with respect to contribution contained in Section 9
hereof shall remain in full force and effect regardless of any investigation
made by or on behalf of the Company or any Underwriter, and shall survive
delivery of and payment for the Securities hereunder and any termination of this
Agreement.

     10.  Substitution of Underwriters: If any Underwriter under this agreement
shall fail or refuse (otherwise than for some reason sufficient to justify in
accordance with the terms hereof, the termination of its obligations hereunder)
to purchase the Securities which it had agreed to purchase on the Time of
Purchase, the Representatives shall immediately notify the Company and the
Representatives and the other Underwriters may, within 36 hours of the giving of
such notice, determine to purchase, or to procure one or more other members of
the National Association of Securities Dealers, Inc. ("NASD") (or, if not
members of the NASD, who are 


                                       15
<PAGE>   16

foreign banks, dealers or institutions not registered under the Securities
Exchange Act and who agree in making sales to comply with the NASD's Rules of
Fair Practice), satisfactory to the Company, to purchase, upon the terms herein
set forth, the number of shares of Securities which the defaulting Underwriter
had agreed to purchase. If any non-defaulting Underwriter or Underwriters shall
determine to exercise such right, the Representatives shall give written notice
to the Company of such determination within 36 hours after the Company shall
have received notice of any such default, and thereupon the Time of Purchase
shall be postponed for such period, not exceeding three business days, as the
Company shall determine. If in the event of such a default, the Representatives
shall fail to give such notice, or shall within such 36-hour period give written
notice to the Company that no other Underwriter or Underwriters, or others, will
exercise such right, then this Agreement may be terminated by the Company, upon
like notice given to the Representatives within a further period of 36 hours. If
in such case the Company shall not elect to terminate this Agreement, it shall
have the right, irrespective of such default:

          (a)     to require such non-defaulting Underwriters to purchase and 
     pay for the respective number of shares which they had severally agreed to
     purchase hereunder, as hereinabove provided, and, in addition, the number
     of shares of Securities which the defaulting Underwriter shall have so
     failed to purchase up to a number of shares thereof equal to one-ninth
     (1/9) of the respective number of shares of Securities which such
     non-defaulting Underwriters have otherwise agreed to purchase hereunder;
     and/or

          (b)     to procure one or more other members of the NASD (or, if not
     members of the NASD, who are foreign banks, dealers or institutions not
     registered under the Exchange Act and who agree in making sales to comply
     with the NASD's Rules of Fair Practice), to purchase, upon the terms herein
     set forth, the number of shares of Securities which such defaulting
     Underwriter had agreed to purchase, or that portion thereof which the
     remaining Underwriters shall not be obligated to purchase pursuant to the
     foregoing clause (a).

          In the event the Company shall exercise its rights under clause (a)
and/or (b) above, the Company shall give written notice thereof to the
Representatives within such further period of 36 hours, and thereupon the Time
of Purchase shall be postponed for such period, not exceeding five business
days, as the Company shall determine. In the event the Company shall be entitled
to but shall not elect to exercise its rights under clause (a) and/or (b), the
Company shall be deemed to have elected to terminate this Agreement.

          Any action taken by the Company under this Section 10 shall not
relieve any defaulting Underwriter from liability in respect of any default of
such Underwriter under this Agreement. Termination by the Company under this
Section 10 shall be without any liability on the part of the Company or any
non-defaulting Underwriting.


                                       16

<PAGE>   17

          In the computation of any period of 36 hours referred to in this
Section 10, there shall be excluded a period of 24 hours in respect of each
Saturday, Sunday or legal holiday which would otherwise be included in such
period of time.

     11.  Termination of Agreement: This Agreement may be terminated at any time
prior to the Time of Purchase by the Representatives, if, prior to such time (i)
trading generally in securities on the New York Stock Exchange shall have been
suspended by the Commission or the New York Stock Exchange, (ii) trading of any
securities of the Company shall have been suspended on any exchange or
over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by federal or New York State
authorities or (iv) there shall have occurred any outbreak or material
escalation of hostilities or any material adverse disruption in financial
markets or any other calamity or crisis, the effect of which on the financial
markets of the United States is such as to impair, in the Representatives'
reasonable judgment, after having made due inquiry, the marketability of the
Securities.

          If the Representatives elect to terminate this Agreement, as provided
in this Section 11, the Representatives will promptly notify the Company and
each other Underwriter by telephone or telecopy, confirmed by letter. If this
Agreement shall not be carried out by any Underwriter for any reason permitted
hereunder, or if the sale of the Securities to the Underwriters as herein
contemplated shall not be carried out because the Company is not able to comply
with the terms hereof, the Company shall not be under any obligation under this
Agreement and shall not be liable to any Underwriter or to any member of any
selling group for the loss of anticipated profits from the transactions
contemplated by this Agreement and the Underwriters shall be under no liability
to the Company nor be under any liability under this Agreement to one another.

          Notwithstanding the foregoing, the provisions of Sections 5(g), 5(i),
8 and 9 shall survive any termination of this Agreement.

     12.  Notices: All notices hereunder shall, unless otherwise expressly
provided, be in writing and be delivered at or mailed to the following addresses
or be sent by telecopy as follows: if to the Underwriters or the
Representatives, to the Representatives at the address or number, as
appropriate, designated in Schedule I hereto, and if the to the Company, to CMS
Energy Corporation, Attention: Senior Vice President and Chief Financial
Officer, Fairlane Plaza South, Suite 1100, 330 Town Center Drive, Dearborn,
Michigan 48126 (Telecopy: 313-436-9548).

     13.  Parties in Interest: The Agreement herein set forth has been and
is made solely for the benefit of the Underwriters, the Company (including the
directors thereof and such of the officers thereof as shall have signed the
Registration Statement), and the controlling persons, if any, referred to in
Section 8 hereof, and their respective successors, assigns, executors and
administrators, and, except as expressly otherwise provided in Section 10
hereof, no other person shall acquire or have any right under or by virtue of
this Agreement.

                                                     MICHAEL D. VAN HEMERT, ESQ.
                                                     ASSISTANT GENERAL COUNSEL


December 14, 1998


CMS Energy Corporation
Fairlane Plaza South
330 Town Center Drive, Suite 1100
Dearborn, MI 48126

Ladies and Gentlemen:

         I am the Assistant General Counsel of CMS Energy Corporation, a
Michigan corporation (the "Company"), and have acted as such in connection with
the Registration Statement on Form S-3 (the "Registration Statement") being
filed by the Company with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "Securities
Act") relating to the registration of $400,000,000 aggregate principal amount of
unsecured senior or subordinated debt securities (the "Debt Securities").
Capitalized terms not otherwise defined herein have the respective meanings
specified in the Registration Statement.

         In rendering this opinion, I have examined and relied upon a copy of
the Registration Statement. I have also examined, or have arranged for the
examination by an attorney or attorneys under my general supervision, originals,
or copies of originals certified to my satisfaction, of such agreements,
documents, certificates and other statements of governmental officials and other
instruments, and have examined such questions of law and have satisfied myself
as to such matters of fact, as I have considered relevant and necessary as a
basis for this opinion. I have assumed the authenticity of the documents
submitted to me as originals, the genuineness of all signatures, the legal
capacity of all natural persons and the conformity with the original documents
of any copies thereof submitted to me for examination.

         Based on the foregoing, it is my opinion that:

         1. The Company is duly incorporated and validly existing under the laws

                             1939, as amended, and duly executed and
                             delivered by the Company and the Trustees;

                    ii)      an appropriate Prospectus Supplement with
                             respect to the particular Debt Securities
                             then being sold by the Company shall have

                    iii)     the Company's Board of Directors or a duly
                             authorized committee thereof shall have duly
                             adopted final resolutions authorizing the
                             issuance and sale of the Company as
                             contemplated by the Registration Statement
                             and the particular Indenture; and

                    iv)      the supplemental Indenture under which the
                             particular Debt Securities are to be issued
                             has been duly authorized, executed and
                             delivered, and the particular Debt
                             Securities then being sold by the Company
                             shall have been duly executed and
                             authenticated as provided in the particular
                             Indenture and such resolutions, and shall
                             have been duly delivered to the purchasers
                             thereof against payment of the agreed
                             consideration therefor.

         For purposes of this opinion, I have assumed that there will be no
changes in the laws currently applicable to the Company and that such laws will
be the only laws applicable to the Company.

         I do not find it necessary for the purposes of this opinion to cover,
and accordingly I express no opinion as to, the application of the securities or
blue sky laws of the various states to the sale of the Debt Securities.

         I am a member of the bar of the State of Michigan and I express no
opinion as to the laws of any jurisdiction other than the State of Michigan and
the federal law of the United States of America.

         I hereby consent to the filing of this opinion as an exhibit to the
Company's Registration Statement on Form S-3 relating to the Debt Securities and
to all references to me included in or made a part of the Registration
Statement.

Very truly yours,
