                         PROSPECTUS SUPPLEMENT SUMMARY
 
     The following summary information is qualified in its entirety by, and
should be read in conjunction with, the more detailed information appearing
elsewhere in this Prospectus Supplement and the accompanying Prospectus or
incorporated by reference herein or therein. The documents so incorporated by
reference are available from CMS Energy upon request.
 
                                  THE COMPANY
 
     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 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, risk management and energy management to
large customers; (iv) transmission, storage and processing of natural gas; and
(v) international energy distribution.
 
     CMS Energy conducts its principal operations through the following seven
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; (vi) natural gas
storage, transmission and processing; and (vii) international energy
distribution. 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 1996 consolidated operating revenue was $4,333 million. This
consolidated operating revenue was derived from its electric utility operations
(approximately 57% or $2,446 million), its gas utility operations (approximately
30% or $1,282 million), gas transmission, storage and marketing (approximately
7% or $320 million), oil and gas exploration and production activities
(approximately 3% or $130 million) and independent power production and other
non-utility activities (approximately 3% or $155 million). 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 electric generation and distribution and gas
transmission and storage revenue for 1996 was $557 million.
 
     Consumers is a public utility serving almost six million of Michigan's nine
and a half million residents in 68 counties in Michigan's Lower Peninsula.
Consumers' service area includes automotive, metal, chemical, food and wood
products industries and a diversified group of other industries. Consumers' 1996
consolidated operating revenue of $3,770 million was derived approximately 65%
($2,446 million) from its electric utility business, approximately 34% ($1,282
million) from its gas utility business and approximately 1% ($42 million) 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.
 
     The foregoing information concerning CMS Energy and its 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 subject, prospective purchasers should refer to the Incorporated
Documents (as defined in the accompanying Prospectus).

                                USE OF PROCEEDS
 
     CMS Energy will apply the net proceeds from the sale of the Shares for its
general corporate purposes, including capital expenditures, investment in
subsidiaries, working capital and repayment of debt.
 
                   SUPPLEMENTAL DESCRIPTION OF CAPITAL STOCK
 
     The following information concerning the Shares supplements, and should be
read in conjunction with, the statements under "Description of Securities --
Capital Stock" in the accompanying Prospectus.
 
GENERAL
 
     The authorized capital stock of CMS Energy consists of 250 million shares
of CMS Energy Common Stock, 60 million shares of Class G Common Stock, no par
value ("Class G Common Stock"), and 10 million shares of CMS Energy Preferred
Stock, $.01 par value ("Preferred Stock"). At November 14, 1997, there were
outstanding 96,035,000 shares of CMS Energy Common Stock and 8,000,000 shares of
Class G Common Stock; no shares of Preferred Stock are issued or outstanding.
The CMS Energy Common Stock and the Class G Common Stock are sometimes together
referred to herein as the "Common Stock."
 
     On January 1, 1995, the businesses of Consumers were internally reorganized
into separate electric utility and gas utility strategic business units. The
initial public offering of Class G Common Stock also occurred in July 1995,
whereby 7,520,000 shares of Class G Common Stock were sold. The Class G Common
Stock is intended to reflect the separate performance of the gas distribution,
storage and transportation businesses conducted by Consumers and Michigan Gas
Storage, a subsidiary of Consumers (such businesses, collectively, have been
attributed to the "Consumers Gas Group"). The CMS Energy Common Stock is
intended to reflect the performance of all businesses of CMS Energy and its
subsidiaries, including the businesses of the Consumers Gas Group, except for
the interest in the Consumers Gas Group attributable to the outstanding shares
of Class G Common Stock.
 
CERTAIN CONSIDERATIONS RELATING TO TWO CLASSES OF COMMON STOCK
 
     Although CMS Energy is aware of no precedent concerning the manner in which
Michigan law would be applied to a board of directors' duties in the context of
multiple classes of common stock with divergent interests, CMS Energy believes
that a Michigan court would hold that a board of directors owes an equal duty to
all shareholders regardless of class and does not have separate or additional
fiduciary duties to the holders of separate classes of stock. That duty requires
each director to act in good faith with the care an ordinarily prudent person in
a like position would exercise under similar circumstances and in a manner such
director reasonably believes to be in the best interests of CMS Energy. CMS
Energy believes that, under Michigan law, a good faith determination by a
disinterested and adequately informed board, or a committee thereof, which
discharges such duty and which the directors honestly believe is in the best
interest of CMS Energy, would be a defense to any challenge by or on behalf of
the holders of either class of Common Stock to the Board of Directors'
determination that could have a disparate effect on each class of Common Stock.
 
     Disproportionate ownership interests of members of the Board of Directors
in one or both classes of Common Stock of CMS Energy or disparate values of the
classes of Common Stock of CMS Energy could create or appear to create potential
conflicts of interest when directors are faced with decisions that could have
different implications for different classes. Nevertheless, CMS Energy believes
that a director would be able to discharge his or her fiduciary duties even if
his or her interests in shares of the classes of Common Stock were
disproportionate and/or had disparate
 
                                       S-6
<PAGE>   7
 
values. CMS Energy's Performance Incentive Stock Plan permits the issuance of
options for, or other incentive awards consisting of, any class of Common Stock
of CMS Energy.
 
     The existence of separate classes of Common Stock could give rise to
occasions when the interests of the holders of Class G Common Stock and holders
of CMS Energy Common Stock may diverge or appear to diverge and determinations
of the Board of Directors could have disparate effects on each class of Common
Stock. Examples include determinations by the Board of Directors to (i) pay or
omit the payment of dividends on either class of Common Stock, (ii) attribute
the proceeds of issuances of securities of CMS Energy either to CMS Energy or to
the equity of the Consumers Gas Group, (iii) attribute consideration to be
received by common stockholders in connection with a merger or consolidation
including CMS Energy to either or both classes of Common Stock, (iv) exchange
CMS Energy Common Stock for all outstanding Class G Common Stock at a premium,
(v) approve dispositions of assets of CMS Energy attributable to the Consumers
Gas Group and (vi) make operational and financial decisions with respect to
either CMS Energy or the Consumers Gas Group that could be considered to be
detrimental to the other. Any determinations made in compliance with applicable
law by the Board of Directors under any of the provisions in the Articles of
Incorporation, as defined in the accompanying Prospectus, would be final and
binding on all shareholders of CMS Energy.
 
     The Board of Directors has adopted certain management and accounting
policies with respect to dividends and the allocation of corporate expenses,
assets and liabilities (including contingent liabilities) including, without
limitation, its intention to attribute assets, liabilities and expenses between
the Consumers Gas Group and CMS Energy only on an arm's-length basis, any and
all of which could be modified or rescinded in the sole discretion of the Board
of Directors without approval of the shareholders. The Board of Directors may
also adopt additional policies depending upon the circumstances, including
policies that would have disparate impacts upon holders of Class G Common Stock
and holders of CMS Energy Common Stock.
 
     The majority of the accounting allocation policies of CMS Energy have a
long standing basis whereby the financial statements for CMS Energy and the
Consumers Gas Group are prepared based upon consistent methods that management
believes are reasonable and appropriate to reflect their respective financial
positions, results of operations and cash flows. Where appropriate, the
financial statements of the Consumers Gas Group reflect the assets, liabilities,
revenues and expenses directly related to it. However, in instances where common
accounts (containing both electric and gas activities) are not readily
attributable to a single business segment, management allocates to CMS Energy
and the Consumers Gas Group financial statements based on certain measures of
business activities, such as gas revenues, salaries, other operations and
maintenance expenditures, number of gas customers in relationship to total
utility customers and/or functional use surveys. Management believes such
allocations are reasonable.
 
DIVIDENDS; RESTRICTIONS AND LIMITATIONS ON ABILITY TO PAY DIVIDENDS
 
     Reference is made to "Description of Securities -- Common Stock -- Dividend
Rights and Policy; Restrictions on Dividends, -- Dividends and Price Range of
CMS Energy Common Stock," and "-- Primary Source of Funds of CMS Energy;
Restrictions on Sources of Dividends" in the accompanying Prospectus for
information about CMS Energy's dividend policies and other matters relating to
dividends on the Shares, including restrictions and limitations on CMS Energy's
ability to pay such dividends.
 
     The high and low sales prices of CMS Energy Common Stock as reported in the
Wall Street Journal under "New York Stock Exchange Composite Transactions" for
the second quarter of 1997, the third quarter of 1997 and the fourth quarter of
1997 through November 14, 1997 were $35.625 and $31.125, $38.063 and $34.875,
and $38.000 and $35.625, respectively. The quarterly cash dividends declared per
share for CMS Energy Common Stock in each of the third and fourth quarters of
1997 were $.30 per share.

     In addition to the restrictions and limitations on payment of dividends
described in the accompanying Prospectus, CMS Energy is subject to the following
contractual restrictions on its ability to pay dividends:
 
     Under the terms of a $1.125 billion Credit Agreement (the "Credit
Agreement") among CMS Energy and certain banks, CMS Energy has agreed that it
will not, and will not permit certain of its subsidiaries, directly or
indirectly, to (i) declare or pay any dividend, payment or other distribution of
assets, properties, cash, rights, obligations or securities on account of any
share of any class of capital stock of CMS Energy or such subsidiaries, or (ii)
purchase, redeem, retire or otherwise acquire for value any such capital stock
(a "Restricted Payment"), unless: (1) no event of default under the Credit
Agreement, or event that with the lapse of time or giving of notice would
constitute such an event of default, has occurred and is continuing, or would
occur as a result of such Restricted Payment and (2) after giving effect to any
such Restricted Payment, the aggregate amount of all such Restricted Payments
since September 30, 1993 shall not have exceeded the sum of: (a) $120,000,000,
(b) 100% of CMS Energy's consolidated net income (as defined in the Indenture
dated as of September 15, 1992, as amended and supplemented (the "Senior Debt
Indenture")) since September 30, 1993 to the end of the most recent fiscal
quarter ending at least 45 days prior to the date of such Restricted Payment
(or, in case such sum shall be a deficit, minus 100% of the deficit), and (c)
the aggregate net proceeds (as defined in the Senior Debt Indenture) received by
CMS Energy for the issuance or sale of, or contribution with respect to, its
capital stock subsequent to September 30, 1993. At September 30, 1997, CMS
Energy could pay cash dividends of $1,154 million pursuant to this restriction.
 
     Under the terms of an Indenture dated as of September 15, 1992, as amended
and supplemented, between CMS Energy and NBD Bank, as Trustee, (the " Senior
Debt Indenture") pursuant to which CMS Energy's 8 1/8% Unsecured Notes Due 2002,
7 5/8% Unsecured Notes Due 2004 and 7 3/8% Unsecured Notes Due 2000 were issued,
so long as any of the Notes are outstanding and until the Notes are rated BBB-
or above (or an equivalent rating) by Standard & Poor's and one Other Rating
Agency (as defined therein), at which time CMS Energy will be permanently
released from the provisions of this limitation, CMS Energy has agreed that it
will not, and will not permit any of its Restricted Subsidiaries, directly or
indirectly, to (i) declare or pay any dividend or make any distribution on the
Capital Stock (as defined in such Indenture) of CMS Energy to the direct or
indirect holders of its Capital Stock (except dividends or distributions payable
solely in its Non-Convertible Capital Stock (as defined in such Indenture) or in
options, warrants or other rights to purchase such Non-Convertible Stock and
except dividends or distributions payable to CMS Energy or a subsidiary; (ii)
purchase, redeem or otherwise acquire or retire for value any Capital Stock of
CMS Energy, or (iii) purchase, repurchase, redeem, defease or otherwise acquire
or retire for value, prior to scheduled maturity or scheduled repayment thereof,
any Subordinated Indebtedness (as defined in such Indenture) (any such dividend,
distribution, purchase, redemption, repurchase, defeasing, other acquisition or
retirement being hereinafter referred to as a "Senior Debt Indenture Restricted
Payment") if at the time CMS Energy or such Subsidiary makes such Senior Debt
Indenture Restricted Payment: (1) an Event of Default (as defined in such
Indenture), or an event that with the lapse of time or the giving of notice or
both would constitute an Event of Default, shall have occurred and be continuing
(or would result therefrom); or (2) the aggregate amount of such Senior Debt
Indenture Restricted Payment and all other Senior Debt Indenture Restricted
Payments made since May 6, 1997 would exceed the sum of: (a) $100,000,000 plus
100% of Consolidated Net Income of CMS Energy (as defined in such Indenture)
from May 6, 1997 to the end of the most recent fiscal quarter ending at least 45
days prior to the date of such Senior Debt Indenture Restricted Payment (or, in
case such sum shall be a deficit, minus 100% of the deficit) and (b) the
aggregate Net Cash Proceeds received by CMS Energy (as defined in such
Indenture) from the issue or sale of or contribution with respect to its Capital
Stock after May 6, 1997. At September 30, 1997, CMS Energy could pay cash
dividends of $161 million pursuant to this restriction.

     The Indenture, dated as of January 15, 1994, as amended and supplemented,
between CMS Energy and The Chase Manhattan Bank, as Trustee (the "GTN
Indenture"), pursuant to which CMS Energy's General Term Notes, Series A, Series
B, Series C or Series D ("GTNs") have been issued, provides that so long as any
GTNs issued thereunder are outstanding and are rated BBB- or above (or an
equivalent rating) by Standard & Poor's and one Other Rating Agency (as defined
in such Indenture), at which time CMS Energy will be permanently released from
the provisions of this limitation, CMS Energy will not, and will not permit any
of its Restricted Subsidiaries (as defined in such Indenture), directly or
indirectly, to, (i) declare or pay any dividend or make any distribution on the
Capital Stock (as defined in such Indenture) (except dividends or distributions
payable solely in Non-Convertible Capital Stock (as defined in such Indenture)
of CMS Energy or in options, warrants or other rights to purchase such
Non-Convertible Capital Stock and except dividends or distributions payable to
CMS Energy or a Subsidiary (as defined in such Indenture)) or (ii) purchase,
redeem or otherwise acquire or retire for value any Capital Stock of CMS Energy
(any such dividend, distribution, purchase, redemption, repurchase, other
acquisition or retirement, being hereinafter referred to as a "GTN Restricted
Payment") if at any time CMS Energy or such Subsidiary makes such GTN Restricted
Payment: (1) an Event of Default (as defined in such Indenture), or an event
that with the lapse of time or the giving of notice or both would constitute an
Event of Default, shall have occurred and be continuing (or would result
therefrom); or (2) the aggregate amount of such GTN Restricted Payment and all
other GTN Restricted Payments made since September 30, 1993, would exceed the
sum of: (a) $120,000,000 plus 100% of Consolidated Net Income(as defined
therein) from September 30, 1993 to the end of the most recent fiscal quarter
ending at least 45 days prior to the date of such GTN Restricted Payment (or, in
case such sum shall be a deficit, minus 100% of the deficit) and (b) the
aggregate Net Proceeds (as defined therein) received by CMS Energy from the
issue or sale of or contribution with respect to its Capital Stock after
September 30, 1993. At September 30, 1997, CMS Energy could pay cash dividends
of $1,154 million pursuant to this restriction.
 
     The foregoing provisions relating to restricted payments do not prohibit:
(i) dividends or other distributions paid by CMS Energy in respect of the
capital stock issued in connection with the acquisition of any business or
assets by CMS Energy where such payments are payable solely from the net
earnings of such business or assets; (ii) any purchase or redemption of capital
stock made by exchange for, or out of the proceeds of the substantially
concurrent sale of, capital stock of CMS Energy (other than certain redeemable
stock or exchangeable stock); (iii) dividends paid within 60 days after the date
of declaration thereof if at such date of declaration such dividends would have
complied with the aforementioned limitations; or (iv) payments pursuant to the
tax sharing agreement among CMS Energy and its subsidiaries.
 
     In June 1997, a CMS Energy affiliated trust issued $172.5 million of 7 3/8%
convertible Trust Preferred Securities ("Preferred Securities"). The Preferred
Securities are convertible at the option of the holder thereof into shares of
CMS Energy Common Stock. Such Preferred Securities are convertible at an initial
conversion rate of 1.2255 shares of CMS Energy Common Stock for each Preferred
Security (equivalent to a purchase price of $40.80 per share of CMS Energy
Common Stock), subject to certain adjustments. On or after July 16, 2001, CMS
Energy may, at its option, cause the conversion rights of the holders of the
Preferred Securities to expire upon certain conditions.
 
     Under the terms of the Indenture dated June 1, 1997 between CMS Energy and
The Bank of New York, as Trustee, as amended and supplemented (the "Subordinated
Debt Indenture") and the Guarantee Agreement dated June 20, 1997 among CMS
Energy and The Bank of New York relating to the Preferred Securities of CMS
Energy Trust I (the "Guarantee") pursuant to which the Preferred Securities and
the related Convertible Subordinated Debentures due 2027 ("Subordinated
Debentures") were issued, CMS Energy will not, and it will not cause any of its
subsidiaries to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
CMS Energy's capital stock, if at such time (i) there shall
 
                                       S-9
<PAGE>   10
 
have occurred any event of which CMS Energy has actual knowledge that (a) with
the giving of notice or the lapse of time, or both, would constitute an Event of
Default (as defined in such Indenture) and (b) in respect of which CMS Energy
shall not have taken reasonable steps to cure, (ii) CMS Energy shall be in
default with respect to its payment of any obligations under the Guarantee or
(iii) CMS Energy shall have given notice of its selection of an Extension Period
(as defined in such Indebtedness) as provided in the Subordinated Debt Indenture
with respect to the Subordinated Debentures and shall not have rescinded such
notice, or such Extension Period, or any extension thereof, shall be continuing.
 
     In addition, Michigan law prohibits payment of a dividend if, after giving
it effect, CMS Energy would not be able to pay its debts as they become due in
the usual course of business, or its total assets would be less than the sum of
its total liabilities plus, unless the articles permit otherwise, the amount
that would be needed, if CMS Energy were to be dissolved at the time of the
distribution, to satisfy the preferential rights upon dissolution of
shareholders whose preferential rights are superior to those receiving the
distribution (including the rights of holders of Preferred Stock, if any). CMS
Energy's net assets available for payment of dividends under the Michigan
Business Corporation Act at September 30, 1997, were $1,832 million.
 
HOLDING COMPANY STRUCTURE; RESTRICTIONS ON SOURCES OF DIVIDENDS
 
     CMS Energy is a legal entity separate and distinct from its various
subsidiaries. As a holding company with no significant operations of its own,
the principal sources of its funds are dividends or other distributions from its
operating subsidiaries (in particular, Consumers), borrowings and sales of
equity. The ability of Consumers and other subsidiaries of CMS Energy to pay
dividends or make distributions to CMS Energy and, accordingly, the ability of
CMS Energy to pay dividends on its capital stock will depend on the earnings,
financial requirements, contractual restrictions of the subsidiaries of CMS
Energy, in particular Consumers, and other factors. CMS Energy's subsidiaries
are separate and distinct legal entities and have no obligation, contingent or
otherwise, to pay any amounts on the Shares or to make any funds available
therefor, whether by dividends, loans or other payments.
 
     Consumers' ability to pay dividends to CMS Energy is restricted by
Consumer's Articles of Incorporation and certain agreements to which it is a
party, as described under "Description of Securities -- Common Stock -- Primary
Source of Funds of CMS Energy; Restrictions on Sources of Dividends" in the
accompanying Prospectus.
 
     In addition, Consumers' Indenture dated January 1, 1996, between Consumers
and Bank of New York as Trustee ("Indenture"), and certain Preferred Securities
Guarantees by Consumers dated January 23, 1996 and September 11, 1997, in
connection with which the 8.36% Trust Preferred Securities of Consumers Power
Company Financing I and the 8.20% Trust Securities of Consumers Energy Financing
II were issued, provide that Consumers shall not declare or pay any dividend on,
make any distributions with respect to, or redeem, purchase or make a
liquidation payment with respect to, any of its capital stock if (i) there shall
have occurred any event that would constitute an event of default under the
Indenture or the trust agreements pursuant to which the Trust Preferred
Securities were issued, (ii) a default with respect to its payment of any
obligations under the Preferred Securities Guarantees or certain Common
Securities Guarantees, or (iii) gives notice of its election to extend the
interest payment period on the subordinated notes issued under the Indenture, at
any time, for up to 20 consecutive quarters provided, however, Consumers may
declare and pay stock dividends where the dividend stock is the same stock as
that on which the dividend is being paid.
 
     Under the provisions of the Michigan Business Corporation Act, at September
30, 1997, Consumers' net assets available for payment of dividends were $1,768
million. Under the most restrictive of the conditions on dividend payments to
which Consumers is subject, and Consumers' dividend policies, in each case as
described herein and in the accompanying Prospectus, at
 
                                      S-10
<PAGE>   11
 
September 30, 1997, $56.9 million of Consumers' retained earnings were available
to pay cash dividends on its common stock. In October 1997, Consumers returned
$50 million of paid in capital to CMS Energy and declared a $57 million common
dividend to be paid in November 1997.
 
                                 TRANSFER AGENT
 
     CMS Energy Common Stock is transferable at the offices of Consumers Energy
Company, 212 W. Michigan Avenue, Jackson, MI 49201. The transfer agent and
registrar for CMS Energy Common Stock is CMS Energy.
 
                                  UNDERWRITING
 
     Under the terms and subject to the conditions contained in an Underwriting
Agreement dated the date hereof (the "Underwriting Agreement"), the Underwriters
have agreed to purchase, and CMS Energy has agreed to sell, the Shares. Subject
to the terms of the Underwriting Agreement, the Underwriters are committed to
take and pay for all of the Shares if any such Shares are taken.
 
     The Underwriters propose to offer the Shares from time to time for sale in
one or more transactions (which may involve block transactions) on the New York
Stock Exchange or otherwise, at market prices prevailing at the time of sale, at
prices related to prevailing market prices or at negotiated prices, subject to
prior sale when, as and if delivered to and accepted by the Underwriters. In
connection with the sale of the Shares, the Underwriters may be deemed to have
received compensation from CMS Energy in the form of underwriting discounts. The
Underwriters may effect such transactions by selling Shares to or through
dealers, and such dealers may receive compensation in the form of discounts,
concessions or commissions from the Underwriters and/or purchasers of such
Shares for whom they may act as agents or to whom they may sell as principal.
 
     In connection with the offering, the Underwriters may purchase and sell the
Shares in the open market. These transactions may include over-allotment
transactions and purchases to cover short positions created by the Underwriters
in connection with the offering. Short positions created by the Underwriters
involve the sale by the Underwriters of a greater number of Shares than they are
required to purchase from CMS Energy in the offering. The Underwriters also may
impose a penalty bid, whereby selling concessions allowed to broker-dealers in
respect of the Shares may be reclaimed by the Underwriters if such Shares are
repurchased by the Underwriters in covering transactions. These activities may
maintain or otherwise affect the market price of the Shares, which may be higher
than the price that might otherwise prevail in the open market; and these
activities, if commenced, may be discontinued at any time. These transactions
may be effected on the New York Stock Exchange, in the over-the-counter market
or otherwise.
 
     CMS Energy has agreed in the Underwriting Agreement not to offer, sell,
contract to sell or otherwise dispose of any shares of its Common Stock or any
securities convertible into or exercisable or exchangeable for its Common Stock,
other than the Shares, for a period of 90 days after the date of this Prospectus
Supplement, without the prior written consent of Goldman, Sachs & Co., provided
that CMS Energy may during such period, in a manner generally consistent with
past practices regarding the number of shares issued by CMS Energy from time to
time thereunder, issue shares of its Common Stock under its Stock Purchase Plan,
Performance Incentive Stock Plan, Employee Stock Ownership Plan and Employee
Savings and Incentive Plan.
 
     CMS Energy has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act. From time to time
the Underwriters have been retained to provide, and continue to provide,
investment banking services to CMS Energy.

                                 LEGAL OPINIONS
 
     Opinions as to the legality of the Shares will be rendered for CMS Energy
by Michael D. VanHemert, Assistant General Counsel for CMS Energy. Certain legal
matters with respect to the Shares will be passed upon by Reid & Priest LLP, New
York, N.Y., counsel for the Underwriter. Reid & Priest LLP provides legal
services to an affiliate of CMS Energy and has, from time to time, provided
legal services to CMS Energy.
 
                                    EXPERTS
 
     The consolidated financial statements and schedule of CMS Energy as of
December 31, 1996 and 1995, and for each of the three years in the period ended
December 31, 1996 incorporated by reference in this Prospectus Supplement and
the accompanying 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 September 30, 1997 and 1996. Arthur Andersen LLP has
applied limited procedures in accordance with professional standards for a
review of such information. However, their separate report thereon states 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 report
on the unaudited interim consolidated financial information because that report
is 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 Supplement and the accompanying 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.

                              PREFERRED SECURITIES
      GUARANTEED TO THE EXTENT SET FORTH HEREIN BY CMS ENERGY CORPORATION
                            ------------------------
 
    CMS Energy Corporation, a Michigan corporation ("CMS Energy"), may offer,
from time to time, (i) shares of Common Stock, par value $.01 per share ("CMS
Energy Common Stock"), (ii) unsecured subordinated debt securities (the
"Subordinated Debentures") consisting of debentures, convertible debentures,
notes and other unsecured evidence of indebtedness, (iii) Stock Purchase
Contracts ("Stock Purchase Contracts") to purchase CMS Energy Common Stock, and
(iv) Stock Purchase Units ("Stock Purchase Units"), each representing ownership
of a Stock Purchase Contract and Subordinated Debentures or Preferred Securities
or debt obligations of third parties, including U.S. Treasury Securities,
securing the holder's obligation to purchase the CMS Energy Common Stock under
the Stock Purchase Contract, or any combination of the foregoing, in each case
in amounts, at prices and on terms to be determined at or prior to the time of
sale. See "Description of Securities."
 
    CMS Energy Trust I and CMS Energy Trust II (each, a "Trust" and
collectively, the "Trusts"), statutory business trusts formed under the laws of
the State of Delaware, may also offer, from time to time, preferred securities
("Preferred Securities") representing preferred undivided beneficial interests
in the assets of the Trust in amounts, at prices and on terms to be determined
at or prior to the time of sale. The undivided common beneficial interests in
the Trust will be owned by CMS Energy. The proceeds from the offering of the
Preferred Securities and the sale of the common securities may be contributed by
the Trust to purchase from CMS Energy Subordinated Debentures in an aggregate
principal amount equal to the aggregate liquidation preference of the Preferred
Securities, bearing interest at an annual rate equal to the annual distribution
rate of such Preferred Securities and having certain redemption terms which
correspond to the redemption terms for the Preferred Securities. The
Subordinated Debentures will rank subordinate in right of payment to all of CMS
Energy's Senior Indebtedness (as defined herein). Distributions on the Preferred
Securities may not be made unless the Trust receives corresponding interest
payments on the Subordinated Debentures from CMS Energy. CMS Energy will
irrevocably guarantee, on a subordinated basis and to the extent set forth
therein, with respect to each of the Trust securities, if any, the payment of
distributions, the redemption price, including all accrued or deferred and
unpaid distributions, and payment on liquidation, but only to the extent of
funds on hand. Each of the guarantees will be unsecured and each will be
subordinate to all Senior Indebtedness of CMS Energy. Upon the occurrence of
certain events (subject to the conditions to be described in an accompanying
Prospectus Supplement) the Trust may be liquidated and the holders of the
Preferred Securities could receive Subordinated Debentures in lieu of any
liquidating cash distribution.
 
    Specific terms of the CMS Energy Common Stock, Subordinated Debentures,
Stock Purchase Contracts, Stock Purchase Units, Preferred Securities, and Trust
guarantees, in respect of which this Prospectus is being delivered (the "Offered
Securities"), will be set forth in an accompanying Prospectus Supplement or
Supplements, together with the terms of the offering of the Offered Securities,
the initial price thereof and the net proceeds from the sale thereof. The
Prospectus Supplement will set forth with regard to the particular Offered
Securities, without limitation, the following: (i) in the case of Subordinated
Debentures, the designation, aggregate principal amount, denomination, maturity,
premium, if any, any exchange, conversion, redemption or sinking fund
provisions, interest rate (which may be fixed or variable), the time or method
of calculating interest payments, the right of CMS Energy, if any, to defer
payment or interest on the Subordinated Debentures and the maximum length of
such deferral, put options, if any, public offering price, ranking, any listing
on a securities exchange and other specific terms of the offering; (ii) in the
case of CMS Energy Common Stock, the designation, number of shares, public
offering price and other specific terms of the Offering, from the sale thereof;
(iii) in the case of Preferred Securities, the designation, number of shares,
liquidation preference per security, initial public offering price, any listing
on a securities exchange, dividend rate (or method of calculation thereof),
dates on which dividends shall be payable and dates from which dividends shall
accrue, any voting rights, any redemption, exchange, conversion or sinking fund
provisions and any other rights, preferences, privileges, limitations or
restrictions relating to a specific series or the Preferred Securities, as the
case may be; and (iv) in the case of Stock Purchase Units, the specific terms of
the Stock Purchase Contracts and any Subordinated Debentures, Preferred
Securities, or debt obligations of third parties securing the holders obligation
to purchase CMS Energy Common Stock under the Stock Purchase Contracts, and the
terms of the offering and sale thereof. The offering price to the public of the
Offered Securities will be limited to $300,000,000 in the aggregate.
 
    The outstanding CMS Energy Common Stock is traded on the New York Stock

                             AVAILABLE INFORMATION
 
     CMS Energy is subject to the informational requirements of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance
therewith files reports and other information with the Securities and Exchange
Commission (the "Commission"). Information, as of particular dates, concerning
CMS Energy's directors and officers, their remuneration, the principal holders
of CMS Energy's securities and any material interest of such persons in
transactions with CMS Energy is disclosed in proxy statements distributed to
shareholders of CMS Energy and filed with the Commission. Such reports, proxy
statements and other information may be inspected and copied at the public
reference facilities maintained by the Commission at Judiciary Plaza, 450 Fifth
Street, N.W., Washington, D.C. 20549, and at the Commission's Regional Offices
located at 500 West Madison Street, Chicago, Illinois 60661 and at Seven World
Trade Center, 13th Floor, New York, New York 10048. Copies of such materials can
be obtained by mail from the Public Reference Section of the Commission at 450
Fifth Street, N.W., Washington, D.C. 20549 at prescribed rates. The Commission
also maintains a Web site (http://www.sec.gov) that contains reports, proxy
statements and other information regarding CMS Energy. The outstanding shares of
CMS Energy Common Stock are listed on the NYSE and reports, proxy statements and
other information concerning CMS Energy may also be inspected and copied at the
offices of such exchange at 20 Broad Street, New York, New York 10005.
 
     No separate financial statements of the Trusts have been included herein.
CMS Energy and the Trusts do not consider that such financial statements would
be material to holders of Preferred Securities because the Trust are newly
organized special purposes entities, have no operating history and no
independent operations and are not engaged in, and do not propose to engage in,
any activity other than as described under "CMS Energy Trust". Further, CMS
Energy believes that financial statements of the Trusts are not material to the
holders of the Preferred Securities since CMS Energy will guarantee the
Preferred Securities such that the holders of the Preferred Securities, with
respect to the payment of distributions and amounts upon liquidation,
dissolution and winding-up, are at least in the same position vis-a-vis the
assets of CMS Energy as a preferred stockholder of CMS Energy. CMS Energy
beneficially owns directly or indirectly all of the undivided beneficial
interests in the assets of the Trusts (other than the beneficial interests
represented by the Preferred Securities). See "CMS Energy Trusts," "Description
of Securities -- Preferred Securities" and "Description of Securities -- The
Guarantees." In future filings under the Exchange Act , an audited footnote to
CMS Energy's annual financial statements will state that the Trusts are
wholly-owned by CMS Energy, that the sole assets of the Trusts are the
Subordinated Debentures of CMS Energy having a specified aggregate principal
amount, and, considered together, the back-up undertakings, including the
Guarantees, constitute a full and unconditional guarantee by CMS Energy of the
Trusts' obligations under the Preferred Securities issued by the Trusts.

                             CMS ENERGY 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 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, risk management and energy
management to large customers; (iv) transmission, storage and processing of
natural gas; and (v) international energy distribution.
 
     CMS Energy conducts its principal operations through the following seven
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; (vi) natural gas
transmission, storage and processing; and (vii) international energy
distribution. 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
 
                                        3
<PAGE>   16
 
assets and/or companies both domestically and internationally. Consideration for
such transactions may involve the delivery of cash or securities.
 
     CMS Energy's 1996 consolidated operating revenue was $4,333 million. This
consolidated operating revenue was derived from its electric utility operations
(approximately 57% or $2,446 million), its gas utility operations (approximately
30% or $1,282 million), gas transmission, storage and marketing (approximately
7% or $320 million), oil and gas exploration and production activities
(approximately 3% or $130 million) and independent power production and other
non-utility activities (approximately 3% or $155 million). Consumers'
consolidated operations in the electric and gas utility businesses account for
the major share of CMS Energy's total assets, revenue and income. The
unconsolidated share of non-utility electric generation, gas transmission and
storage and international energy distribution revenue for 1996 was $557 million.
 
     Consumers is a public utility serving gas or electricity to almost six
million of Michigan's nine and a half million residents in all of the 68
counties in Michigan's Lower Peninsula. Industries in Consumers' service area
include automotive, metal, chemical, food and wood products and a diversified
group of other industries. Consumers' 1996 consolidated operating revenue of
$3,770 million was derived approximately 65% ($2,446 million) from its electric
utility business and approximately 34% ($1,282 million) from its gas 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.
 
                               CMS ENERGY TRUSTS
 
     Each of CMS Energy Trust I and CMS Energy Trust II is a statutory business
trust formed under the Delaware Business Trust Act (the "Trust Act") pursuant to
(i) a trust agreement executed by CMS Energy, as sponsor, and the trustees of
CMS Energy Trust I and CMS Energy Trust II (the "CMS Trustees") and (ii) the
filing of a certificate of trust with the Secretary of State of the State of
Delaware. Each trust agreement will be amended and restated in its entirety (as
so amended and restated, the "Trust Agreement") and will be qualified as an
indenture under the Trust Indenture Act of 1939, as amended (the "Trust
Indenture Act"). CMS Energy will directly or indirectly acquire common
securities of each Trust in an aggregate liquidation amount equal to
approximately 3% of the total capital of the Trust. Each Trust exists for the
exclusive purposes of (i) issuing the Preferred Securities and common securities
(the "Common Securities" and, together with the Preferred Securities, the "Trust
Securities") representing undivided beneficial interests in the assets of the
Trust, (ii) investing the gross proceeds of the Trust Securities in the
Subordinated Debentures and (iii) engaging in only those other activities
necessary or incidental thereto. Each Trust has a term of approximately 30
years, but may terminate earlier as provided in the Trust Agreement.
 
     Pursuant to the Trust Agreement, the number of CMS Trustees will initially
be three. Two of the CMS Trustees (the "Administrative Trustees") will be
persons who are employees or officers of or who are affiliated with CMS Energy.
The third trustee will be a financial institution that is unaffiliated with CMS
Energy, which trustee will serve as property trustee under the Trust Agreement
and as indenture trustee for the purposes of compliance with the provisions of
the Trust Indenture Act (the "Property Trustee"). Initially, The Bank of New
York, a New York banking corporation, will be the Property Trustee until removed
or replaced by the holder of the Common Securities. For the purpose of
compliance with the provisions of the Trust Indenture Act, The Bank of New York
will also act a trustee (the "Guarantee Trustee") under the Preferred Securities
Guarantee and The Bank of New York (Delaware) will act as the Delaware Trustee
for the purposes of the Trust Act (as defined herein), until removed or replaced
by the holder of the Common Securities. See "Description of Securities -- The
Guarantees."
 
     The Property Trustee will hold title to the Subordinated Debentures for the
benefit of the holders of the Trust Securities and the Property Trustee will
have the power to exercise all rights, powers
 
                                        4
<PAGE>   17
 
and privileges under the Subordinated Debt Indenture (as defined herein) as the
holder of the Subordinated Debentures. In addition, the Property Trustee will
maintain exclusive control of a segregated non-interest bearing bank account
(the "Property Account") to hold all payments made in respect of the
Subordinated Debentures for the benefit of the holders of the Trust Securities.
The Property Trustee will make payments of distributions and payments on
liquidation, redemption and otherwise to the holders of the Trust Securities out
of funds from the Property Account. The Guarantee Trustee will hold the
Preferred Securities Guarantee for the benefit of the holders of the Preferred
Securities. CMS Energy, as the direct or indirect holder of all the Common
Securities, will have the right to appoint, remove or replace any CMS Trustee
and to increase or decrease the number of CMS Trustees; provided, that the
number of CMS Trustees shall be at least three, a majority of which shall be
Administrative Trustees. CMS Energy will pay all fees and expenses related to
CMS Energy Trust and the offering of the Trust Securities.
 
     The rights of the holders of the Preferred Securities, including economic
rights, rights to information and voting rights, are set forth in the Trust
Agreement, the Trust Act and the Trust Indenture Act.
 
     The trustee in the State of Delaware is The Bank of New York (Delaware),
White Clay Center, Route 273, Newark, Delaware 19711. The principal place of
business of each Trust shall be c/o CMS Energy Corporation, Fairlane Plaza
South, Suite 1100, 330 Town Center Drive, Dearborn, Michigan 48126-2712.
 
                                USE OF PROCEEDS
 
     The proceeds received by the Trust from the sale of its Preferred
Securities or the common securities will be invested in the Subordinated
Debentures. As will be more specifically set forth in the applicable Prospectus
Supplement, CMS Energy will use such borrowed amounts and the net proceeds from
the sale of the CMS Energy Common Stock and any Subordinated Debentures offered
hereby for its general corporate purposes, including capital expenditures,
investment in subsidiaries, working capital and repayment of debt.

(1) For the year ended December 31, 1992, fixed charges exceeded earnings by
    $441 million. Earnings as defined include a $520 million pretax loss on the
    settlement of MCV power purchases, $(15) million for potential customer
    refunds and other reserves related to 1992 but recorded in 1991, and $6
    million relating to CMS Generation's reduction in its investment in The
    Oxford Energy Company. The ratio of earnings to fixed charges and the ratio
    of earnings to fixed charges and preferred stock dividends would have been
    1.33 and 1.29, respectively, excluding these amounts.

before income taxes, net interest charges and the estimated interest portion of
lease rentals.
 
                           DESCRIPTION OF SECURITIES
 
CAPITAL STOCK
 
     The following summary of certain rights of the holders of CMS Energy
capital stock does not purport to be complete and is qualified in its entirety
by express reference to the Restated Articles of Incorporation of CMS Energy
(the "Articles of Incorporation") and the By-Laws of CMS Energy, copies of which
are filed as exhibits to the Registration Statement of which this Prospectus is
a part, and by express reference to the Registration Statement on Form 8-B/A,
which is incorporated into this Prospectus by reference. See "Incorporation of
Certain Documents by Reference" herein.
 
     The authorized capital stock of CMS Energy consists of 250 million shares
of CMS Energy Common Stock, 60 million shares of Class G Common Stock, no par
value ("Class G Common Stock"), and 10 million shares of CMS Energy Preferred
Stock, $.01 par value ("Preferred Stock"). At June 10, 1997, there were
outstanding 95,502,754 shares of CMS Energy Common Stock and 8,000,435 shares of
Class G Common Stock; no shares of Preferred Stock are issued or outstanding.
The CMS Energy Common Stock and the Class G Common Stock are sometimes together
referred to herein as the "Common Stock."
 
COMMON STOCK
 
     The Class G Common Stock is intended to reflect the separate performance of
the gas distribution, storage and transportation businesses conducted by
Consumers and Michigan Gas Storage, a subsidiary of Consumers (such businesses,
collectively, have been attributed to the "Consumers Gas Group"). The CMS Energy
Common Stock is intended to reflect the performance of all businesses of CMS
Energy and its subsidiaries, including the businesses of the Consumers Gas
Group, except for the interest in the Consumers Gas Group attributable to the
outstanding shares of Class G Common Stock.
 
     DIVIDEND RIGHTS AND POLICY; RESTRICTIONS ON DIVIDENDS
 
     Dividends on the CMS Energy Common Stock are paid at the discretion of the
Board of Directors based primarily upon the earnings and financial condition of
CMS Energy, including the Consumers Gas Group, except for the interest in the
Consumers Gas Group attributable to the outstanding shares of the Class G Common
Stock, and other factors. Dividends are payable out of the assets of CMS Energy
legally available therefore, including the Available Class G Dividend Amount (as
defined in the Articles of Incorporation).
 
     Dividends on the Class G Common Stock are paid at the discretion of the
Board of Directors based primarily upon the earnings and financial condition of
the Consumers Gas Group, and, to a lesser extent, CMS Energy as a whole.
Dividends are payable out of the lesser of (i) the assets of CMS Energy legally
available therefore and (ii) the Available Class G Dividend Amount. Although the
Available Class G Dividend Amount is intended to reflect the amount available
for dividends to holders of outstanding Class G Common Stock, it is also legally
available for dividends to holders of CMS Energy Common Stock.
 
     CMS Energy, in the sole discretion of its Board of Directors could pay
dividends exclusively to the holders of CMS Energy Common Stock, exclusively to
the holders of Class G Common Stock, or to the holders of both of such classes
in equal or unequal amounts.
 
     CMS Energy is a holding company and its assets consist primarily of
investments in its subsidiaries. As a holding company with no significant
operations of its own, the principal sources of its funds are dependent
primarily upon the earnings of its subsidiaries (in particular, Consumers),
 
                                        6
<PAGE>   19
 
borrowings and sales of equity. CMS Energy's ability to pay dividends, including
dividends on CMS Energy Common Stock, 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, accordingly, the ability of CMS Energy to pay dividends on its
capital stock will depend on the earnings, financial requirements, contractual
restrictions of the subsidiaries of CMS Energy, in particular, Consumers, and
other factors.
 
     Dividends on capital stock of CMS Energy are limited by Michigan law to
legally available assets of CMS Energy. Distributions on Common Stock may be
subject to the rights of the holders, if any, of the CMS Energy Preferred Stock.
 
     There are restrictions on CMS Energy's ability to pay dividends contained
in certain revolving credit and term loan agreements, the Indenture dated as of
September 15, 1992, as amended and supplemented, between CMS Energy and NBD
Bank, as Trustee, and the Indenture dated as of January 15, 1994, as amended and
supplemented, between CMS Energy and The Chase Manhattan Bank, as Trustee. A
discussion of specific restrictions on CMS Energy's ability to pay dividends
will be set forth in an accompanying Prospectus Supplement pursuant to which
convertible Subordinated Debentures, convertible Preferred Securities or CMS
Energy Common Stock are offered.
 
     VOTING RIGHTS
 
     The holders of CMS Energy Common Stock vote with the holders of Class G
Common Stock as a single class, except on matters which would be required by law
or the Articles of Incorporation to be voted on by class. Each holder of Common
Stock is entitled to one vote for each share of Common Stock held by such holder
on each matter voted upon by the shareholders. Such right to vote is not
cumulative. A majority of the votes cast by the holders of shares entitled to
vote thereon is sufficient for the adoption of any question presented, except
that certain provisions of the Articles of Incorporation relating to special
shareholder meetings, the removal, indemnification and liability of the Board of
Directors and the requirements for amending these provisions may not be amended,
altered, changed or repealed unless such amendment, alteration, change or repeal
is approved by the affirmative vote of at least 75% of the outstanding shares
entitled to vote thereon.
 
     Under Michigan law, the approval of the holders of a majority of the
outstanding shares of a class of Common Stock, voting as a separate class, would
be necessary for authorizing, effecting or validating the merger or
consolidation of CMS Energy into or with any other corporation if such merger or
consolidation would adversely affect the powers or special rights of such class
of stock, and to authorize any amendment to the Articles of Incorporation that
would increase or decrease the aggregate number of authorized shares of such
class (except pursuant to Section 303 of the Michigan Business Corporation Act)
or alter or change the powers, preferences or special rights of the shares of
such class so as to affect them adversely. The Articles of Incorporation also
provide that unless the vote or consent of a greater number of shares shall then
be required by law, the vote or consent of the holders of a majority of all the
shares of either class of Common Stock then outstanding, voting as a separate
class, will be necessary for authorizing, effecting or validating the merger or
consolidation of CMS Energy into or with any other entity if such merger or
consolidation would adversely affect the powers or special rights of such class
of Common Stock, either directly by amendment to the Articles of Incorporation
or indirectly by requiring the holders of such class to accept or retain, in
such merger or consolidation, anything other than (i) shares of such class or
(ii) shares of the surviving or resulting corporation, having, in either case,
powers and special rights identical to those of such class prior to such merger
or consolidation. The effect of these provisions may be to permit the holders of
a majority of the outstanding shares of either class of Common Stock to block
any such merger or amendment which would adversely affect the powers or special
rights of holders of such class of Common Stock.
 
                                        7
<PAGE>   20
 
     PREEMPTIVE RIGHTS
 
     The Articles of Incorporation provide that holders of Common Stock will
have no preemptive rights to subscribe for or purchase any additional shares of
the capital stock of CMS Energy of any class now or hereafter authorized, or
Preferred Stock, bonds, debentures, or other obligations or rights or options
convertible into or exchangeable for or entitling the holder or owner to
subscribe for or purchase any shares of capital stock, or any rights to exchange
shares issued for shares to be issued.
 
     LIQUIDATION RIGHTS
 
     In the event of the dissolution, liquidation or winding up of CMS Energy,
whether voluntary or involuntary, after payment or provision for payment of the
debts and other liabilities of CMS Energy and after there shall have been paid
or set apart for the holders of Preferred Stock the full preferential amounts
(including any accumulated and unpaid dividends) to which they are entitled, the
holders of CMS Energy Common Stock and Class G Common Stock shall be entitled to
receive, on a per share basis, the same portion of all of the assets of CMS
Energy remaining for distribution to the holders of Common Stock, regardless of
whether or not any of such assets were attributed to the Consumers Gas Group.
Neither the merger or consolidation of CMS Energy into or with any other
corporation, nor the merger or consolidation of any other corporation into or
with CMS Energy nor any sale, transfer or lease of all or any part of the assets
of CMS Energy, shall be deemed to be a dissolution, liquidation or winding up
for the purposes of this provision.
 
     Because CMS Energy has subsidiaries which have debt obligations and other
liabilities of their own, CMS Energy's rights and the rights of its creditors
and its stockholders to participate in the distribution of assets of any
subsidiary upon the latter's liquidation or recapitalization will be subject to
prior claims of the subsidiary's creditors, except to the extent that CMS Energy
may itself be a creditor with recognized claims against the subsidiary.
 
     SUBDIVISION OR COMBINATION
 
     If CMS Energy subdivides (by stock split, stock dividend or otherwise) or
combines (by reverse stock split or otherwise) the outstanding shares of either
Class G Common Stock or CMS Energy Common Stock, the voting and liquidation
rights of shares of CMS Energy Common Stock relative to Class G Common Stock
will be appropriately adjusted so as to avoid any dilution in aggregate voting
or liquidation rights of either class of Common Stock. For example, in case CMS
Energy were to effect a two-for-one split of Class G Common Stock, the per share
liquidation rights of CMS Energy Common Stock would be multiplied by two in
order to avoid dilution in the aggregate liquidation rights of holders of CMS
Energy Common Stock and each post-split share of Class G Common Stock would have
one-half of a vote.
 
     EXCHANGES
 
     The Articles of Incorporation do not provide for either the mandatory or
optional exchange or redemption of CMS Energy Common Stock but do provide that
Class G Common Stock may be exchanged for CMS Energy Common Stock as described
in the Registration Statement on Form 8-B/A incorporated by reference herein.
CMS Energy cannot predict the impact of the potential for such exchanges on the
market prices of the CMS Energy Common Stock.
 
     CMS Energy may exchange the Class G Common Stock for a proportionate number
of shares of a subsidiary that holds all the assets and liabilities attributed
to the Consumers Gas Group, and no other assets and liabilities. If CMS Energy
transfers all or substantially all of the properties and assets attributed to
the Consumers Gas Group, CMS Energy is required, subject to certain exceptions
and conditions, to exchange each outstanding share of Class G Common Stock for a
number of shares of CMS Energy Common Stock having a Fair Market Value (defined
in the Articles of Incorporation) equal to 110% of the Fair Market Value of one
share of Class G Common Stock.
 
                                        8
<PAGE>   21
 
     CMS Energy may, in the sole discretion of the Board of Directors, at any
time, exchange each outstanding share of Class G Common Stock for a number of
shares of CMS Energy Common Stock having a Fair Market Value equal to 115% of
the Fair Market Value of one share of Class G Common Stock.
 
     CMS Energy cannot predict the impact of the potential for such exchanges on
the market prices of the CMS Energy Common Stock.
 
     TRANSFER AGENT AND REGISTRAR
 
     CMS Energy Common Stock and Class G Common Stock are transferable at
Consumers Energy Company, 212 W. Michigan Avenue, Jackson, MI 49201. CMS Energy
is the registrar and transfer agent for CMS Energy Common Stock and Class G
Common Stock.
 
DIVIDENDS AND PRICE RANGE OF CMS ENERGY COMMON STOCK
 
     CMS Energy has paid dividends on its outstanding CMS Energy Common Stock
each year since its inception except 1987 and 1988. At June 10, 1997, there were
approximately 89,292 CMS Energy Common Stock shareholders of record. Future
dividends will depend upon CMS Energy's earnings, financial condition and other
factors.

     On May 27, 1997, the CMS Energy Board of Directors approved an increase in
the dividend to an annualized rate of $1.20 per share ($.30 per quarter). The
increase will be effective with the next scheduled quarterly dividend payment in
August 1997. The last reported sale price of the CMS Energy Common Stock on June
13, 1997 on the NYSE was $33.875.

PREFERRED STOCK
 
     The authorized Preferred Stock may be issued without the approval of the
holders of Common Stock in one or more series, from time to time, with each such
series to have such designation, powers, preferences and relative,
participating, optional or other special rights, voting rights, if any, and
qualifications, limitations or restrictions thereof, as shall be stated in a
resolution providing for the issue of any such series adopted by CMS Energy's
Board of Directors. The Articles of Incorporation provide that holders of
Preferred Stock will not have any preemptive rights to subscribe for or purchase
any additional shares of the capital stock of CMS Energy of any class now or
hereafter authorized, or any Preferred Stock, bonds, debentures or other
obligations or rights or options convertible into or exchangeable for or
entitling the holder or owner to subscribe for or purchase any shares of capital
stock. The future issuance of Preferred Stock may have the effect of delaying,
deterring or preventing a change in control of CMS Energy.
 
PRIMARY SOURCE OF FUNDS OF CMS ENERGY; RESTRICTIONS ON SOURCES OF DIVIDENDS
 
     The ability of CMS Energy to pay (i) dividends on its capital stock and
(ii) its indebtedness, including the Subordinated Debentures, depends and will
depend substantially upon timely receipt of sufficient dividends or other
distributions from its subsidiaries, in particular Consumers. Consumers' ability
to pay dividends on its common stock depends upon its revenues, earnings and
other factors. Consumers' revenues and earnings will depend substantially upon
rates authorized by the MPSC.
 
     Consumers' ability to pay dividends is restricted by its First Mortgage
Bond Indenture (the "Mortgage Indenture") and its Articles of Incorporation
("Articles"). The Mortgage Indenture provides that Consumers can only pay
dividends on its common stock out of retained earnings accumulated subsequent to
September 30, 1945, provided that upon such payment, there shall remain of such
retained earnings an amount equivalent to any deficiency in maintenance and
replacement expenditures as compared with maintenance and replacement
requirements since December 31, 1945. Because of restrictions in its Articles
and Mortgage Indenture, Consumers was prohibited from paying dividends on its
common stock from June 1991 to December 31, 1992. However, as of December 31,
1992, Consumers effected a quasi-reorganization in which Consumers' accumulated
deficit of $574 million was eliminated against other paid-in capital. With the
accumulated deficit eliminated, Consumers satisfied the requirements under its
Mortgage Indenture and resumed paying dividends on its common stock in May 1993.
 
     Consumers' Articles also provide two restrictions on its payment of
dividends on its common stock. First, prior to the payment of any common stock
dividend, Consumers must reserve retained earnings after giving effect to such
dividend payment of at least (i) $7.50 per share on all then outstanding shares
of its preferred stock, (ii) in respect to its Class A Preferred Stock, 7.5% of
the aggregate amount established by its Board of Directors to be payable on the
shares of each series thereof in the event of involuntary liquidation of
Consumers, and (iii) $7.50 per share on all then outstanding shares of all other
stock over which its preferred stock and Class A Preferred Stock do not have
preference as to the payment of dividends and as to assets. Second, dividend
payments during the 12 month period ending with the month the proposed payment
is to be paid are limited to: (i) 50% of net income available for the payment of
dividends during the base period (hereinafter defined) if the ratio of common
stock and surplus to total capitalization and surplus for 12 consecutive
calendar months within the 14 calendar months immediately preceding the proposed
dividend payment (the "base period"), adjusted to reflect the proposed dividend,
is less than 20%; and (ii) 75% of net income available for the payment of
dividends during the base period if the ratio of common stock and surplus to
total capitalization and surplus for the base period, adjusted to reflect the
proposed dividend, is at least 20% but less than 25%.
 
     Consumers' Articles also prohibit the payment of cash dividends on its
common stock if Consumers is in arrears on preferred stock dividend payments.
 
                                       10
<PAGE>   23
 
     In addition, Michigan law prohibits payment of a dividend if, after giving
it effect, Consumers would not be able to pay its debts as they become due in
the usual course of business, or its total assets would be less than the sum of
its total liabilities plus, unless the articles permit otherwise, the amount
that would be needed, if Consumers were to be dissolved at the time of the
distribution, to satisfy the preferential rights upon dissolution of
shareholders whose preferential rights are superior to those receiving the
distribution. Consumers' net assets available for payment of dividends under the
Michigan Business Corporation Act at March 31, 1997 were $1,748 million.
Currently, it is Consumers' policy to pay annual dividends equal to 80% of its
annual consolidated net income. Under the most restrictive of these conditions,
and Consumers current dividend policy, at March 31, 1997, $70 million of
Consumers' retained earnings were available to pay cash dividends on its common
stock. Consumers' Board of Directors reserves the right to change this policy at
any time.
 
     In 1996, Consumers paid $200 million in common stock dividends to CMS
Energy. Consumers also paid dividends on its common stock of $70 million on May
22, 1997.
 
SUBORDINATED DEBENTURES
 
     The Subordinated Debentures will be issued under an Indenture (the
"Subordinated Debt Indenture), between CMS Energy and The Bank of New York as
Trustee (the "Subordinated Debt Trustee"). The descriptions of the provisions of
the Subordinated Debentures and the Subordinated Debt Indenture contained herein
are brief summaries of such provisions and do not purport to be complete. The
form of the Subordinated Debt Indenture is filed as an exhibit to the
Registration Statement of which this Prospectus is a part, and reference is made
thereto for the respective definitive provisions of such Indenture. 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 Indenture. Section references below are references to sections of the
Subordinated Debt Indenture.
 
     GENERAL
 
     CMS Energy will offer under this Prospectus unsecured Subordinated
Debentures. The Subordinated Debt Indenture does not limit the aggregate
principal amount of Subordinated Debentures which may be issued thereunder.
Subordinated Debentures may be issued under the Subordinated Debt Indenture from
time to time in one or more series. The Subordinated Debentures shall mature on
a date not less than nine months nor more than 40 years after the date of
issuance. (Section 2.3) Capitalized terms used in this section "Subordinated
Debentures" and not otherwise specifically defined in this Prospectus shall have
the meanings respectively set forth in the Subordinated Debt Indenture. The
terms of any Subordinated Debentures 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 Subordinated Debentures.
 
     CMS Energy is a holding company and its assets consist primarily of
investments in its subsidiaries. The Subordinated Debentures will be obligations
exclusively of CMS Energy. CMS Energy's ability to service its indebtedness,
including the Subordinated Debentures, 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 Subordinated Debentures 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 Subordinated Debentures, 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
 
                                       11
<PAGE>   24
 
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 May 31, 1997, CMS Energy's subsidiaries had total indebtedness
for borrowed money (including capital lease obligations and excluding
intercompany indebtedness) of approximately $2,616 million.
 
     The applicable Prospectus Supplement will set forth the following terms
relating to the Subordinated Debentures: (1) the specific designation of the
Subordinated Debentures; (2) any limit on the aggregate principal amount of the
Subordinated Debentures; (3) the date or dates, if any (and whether fixed or
extendible), on which the Subordinated Debentures will mature; (4) the rate or
rates per annum (which may be fixed or variable) at which the Subordinated
Debentures will bear interest, if any, the date or dates on which any such
interest will be payable and the regular record dates for any interest payable
on the Subordinated Debentures; (5) the place or places where the principal of
and any interest on the Subordinated Debentures shall be payable and where such
Subordinated Debentures may be surrendered for registration of transfer or
exchange; (6) any provisions relating to the issuance of the Subordinated
Debentures at an original issue discount; (7) the option, if any, of CMS Energy
to redeem the Subordinated Debentures and the periods within which or the dates
on which, the prices at which and the terms and conditions upon which, such
Subordinated Debentures may be redeemed, in whole or in part, upon the exercise
of such option; (8) the obligation, if any, of CMS Energy to redeem such
Subordinated Debentures pursuant to any sinking fund or other mandatory
redemption provisions or at the option of the holder and the periods within
which or the dates on which, the prices at which and the terms and conditions
upon which such Subordinated Debentures will be redeemed, in whole or in part,
pursuant to such obligation; (9) the obligation, if any, of CMS Energy to permit
the conversion of the Subordinated Debentures into CMS Energy Common Stock, and
the terms and conditions upon which such conversion shall be effected; (10) the
denominations in which such Subordinated Debentures will be issued and whether
the Subordinated Debentures will be issuable in registered form or bearer form
or both, and, if issuable in bearer form, the restrictions as to the offer, sale
and delivery of the Subordinated Debentures in bearer form and as to exchanges
between registered and bearer form; (11) whether the Subordinated Debentures
will be issuable in the form of one or more temporary or permanent global
securities and, if so, the identity of the depository for such global
securities; (12) whether and under what circumstances CMS Energy will pay
additional amounts with respect to the Subordinated Debentures to a non-United
States Person (as defined in such Prospectus Supplement) on account of any tax,
assessment or governmental charge withheld or deducted and, if so, whether CMS
Energy will have the option to redeem such Subordinated Debentures rather than
pay such additional amounts; and (13) any other terms of the Subordinated
Debentures not inconsistent with the Subordinated Debt Indenture, including
covenants and events of default relating solely to the Subordinated Debentures.
Subordinated Debentures may be issued at a substantial discount from the stated
principal amount thereof ("Original Issue Discount Securities"). United States
federal income tax consequences and other special considerations applicable
thereto or to other Subordinated Debentures offered and sold at par which are
treated as having been issued at a discount for United States federal income tax
purposes will be described in the Prospectus Supplement relating thereto.
 
     CONCERNING THE TRUSTEE
 
     The Bank of New York, the Trustee under the Subordinated Debt Indenture, is
one of a number of banks with which CMS Energy and its subsidiaries maintain
ordinary banking relationships, including credit facilities.
 
     EXCHANGE AND TRANSFER
 
     Subordinated Debentures may be presented for exchange and registered
Subordinated Debentures 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
 
                                       12
<PAGE>   25
 
payment of any taxes or other governmental charges due in connection therewith,
subject to any applicable limitations contained in the Subordinated Debt
Indenture. Subordinated Debentures in bearer form and the coupons appertaining
thereto, if any, will be transferable by delivery. (Section 2.8)
 
     PAYMENT
 
     Unless otherwise indicated in the applicable Prospectus Supplement, payment
of the principal of and the premium and interest, if any, on all Subordinated
Debentures 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. (Sections 3.1 and
3.2) Unless otherwise indicated in the applicable Prospectus Supplement, payment
of any interest due on Subordinated Debentures in registered form will be made
to the Persons in whose name such Subordinated Debentures are registered at the
close of business on the Record Date for such interest payments. (Section
2.3(f))
 
     EVENTS OF DEFAULT
 
     The occurrence of any of the following events with respect to the
Subordinated Debentures of any series will constitute an "Event of Default" with
respect to the Subordinated Debentures of such series: (a) default for 30 days
in the payment of any interest on any of the Subordinated Debentures 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 Debentures 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 Debentures; (b) default in the payment when due of any of
the principal of or the premium, if any, on any of the Subordinated Debentures
of such series, whether at maturity, upon redemption, acceleration or otherwise
(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 Debentures 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 Debentures; (c) failure by CMS Energy to deliver shares of CMS
Energy Common Stock upon an appropriate election by holders of the Subordinated
Debentures to convert such Subordinated Debentures; (d) default in the deposit
or payment of any sinking fund or analogous payment in respect of any
Subordinated Debentures of such series (whether or not payment is prohibited by
the subordination provisions of the Subordinated Debt Indenture); (e) 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 Debentures of such series after written notice thereof as provided
in the Subordinated Debt Indenture; (f) certain events of bankruptcy, insolvency
or reorganization relating to CMS Energy; (g) entry of final judgments against
CMS Energy or Consumers aggregating in excess of $25,000,000 which remain
undischarged or unbonded for 60 days; (h) 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; or (i)
the voluntary or involuntary dissolution, winding-up or termination of a Trust,
except in connection with the distribution of Subordinated Debentures to the
holders of Preferred Securities in liquidation of such Trust, the redemption of
all outstanding Trust Securities of the Trust and certain mergers,
consolidations or amalgamations permitted by the Trust Agreement of such Trust.
Additional Events of Default may be prescribed for the benefit of the
 
                                       13
<PAGE>   26
 
Holders of a particular series of Subordinated Debentures and will be described
in the Prospectus Supplement relating to such Subordinated Debentures. (Section
5.1)
 
     If an Event of Default on any series of Subordinated Debentures 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
Debentures of such series then Outstanding may declare the principal of all
Subordinated Debentures of such series and the interest, if any, accrued thereon
to be due and payable immediately and, should the Subordinated Debenture Trustee
or the holders of the Subordinated Debentures fail to make such declaration, the
holders of at least 25% in aggregate liquidation amount of the Preferred
Securities then outstanding shall have such right. (Section 5.1)
 
     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 Debentures 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 Debentures of the affected series then Outstanding
and, should the holders of the Subordinated Debentures fail to waive such
defaults, the holders of a majority in aggregate liquidation amount of the
Preferred Securities shall have such right. (Section 5.1)
 
     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 Debentures, unless such Holders shall have offered to the
Subordinated Debt Trustee reasonable indemnity. (Sections 6.1 and 6.2(d))
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 Debentures 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 Debentures of such
affected series. (Sections 5.9 and 6.2)
 
     The Subordinated Debt Indenture provides that no Holder of Subordinated
Debentures 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
Debentures 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 reasonable indemnity, the
Subordinated Debt Trustee shall not have instituted such action within 60 days
of such request and 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 Debentures of the affected series
then Outstanding (voting as one class). (Sections 5.6, 5.7 and 5.9)
 
     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.
(Section 4.3(d)) The Subordinated Debt Indenture provides that the Subordinated
Debt Trustee may withhold notice to the Holders of the Subordinated Debentures
of any series of any default affecting such series (except defaults as to
payment of principal, premium or interest on the Subordinated Debentures of such
series) if it considers such
 
                                       14
<PAGE>   27
 
withholding to be in the interests of the Holders of the Subordinated Debentures
of such series. (Section 5.11)
 
     SUBORDINATION
 
     The Subordinated Debt Indenture provides (and each Holder of Subordinated
Debentures by acceptance thereof agrees) that the Subordinated Debentures will
be subordinated in right of payment to the prior payment in full of all Senior
Indebtedness (as defined herein) of CMS Energy. (Section 12.1) No payment on
account of principal of, premium, if any, or interest on the Subordinated
Debentures and no acquisition of, or payment on account of any sinking fund for,
the Subordinated Debentures 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 Debentures or to
acquire any Subordinated Debentures or on account of any sinking fund provisions
applicable to Subordinated Debentures. 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. (Section 12.2) The Subordinated Debt
Indenture provisions described in this paragraph, however, do not prevent CMS
Energy from making sinking fund payments in Subordinated Debentures 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 Debentures 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 Debentures 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 Debentures. (Section 12.3) In the event that
notwithstanding such subordination provisions, any payment or distribution of
assets of any kind or character is made on the Subordinated Debentures before
all Senior Indebtedness is paid in full, the Subordinated Debt Trustee or the
Holders of Subordinated Debentures receiving such payment will be required to
pay over such payment or distribution to the Holders of such Senior
Indebtedness. (Sections 12.2 and 12.3) Subject to the payment in full of all
Senior Indebtedness, the rights of the Holders of the Subordinated Debentures
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 Debentures are paid in full. As a result of
the subordination provisions, in the event of CMS Energy's insolvency, Holders
of the Subordinated Debentures may recover ratably less than senior creditors of
CMS Energy.
 
     "Senior Indebtedness" means the principal of and premium, if any, and
interest (including interest accruing on or after the filing of any petition in
bankruptcy relating to CMS Energy whether or not such claim for post-petition
interest is allowed in such proceeding) 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, except indebtedness to trade
creditors or assumed by CMS Energy in the ordinary course of business in
connection with the obtaining of goods, materials or
 
                                       15
<PAGE>   28
 
services) or evidenced by debentures (other than the Subordinated Debentures),
notes, bankers' acceptances or other corporate Subordinated Debentures or
similar instruments issued by CMS Energy; (ii) all capital lease obligations of
CMS Energy; (iii) obligations with respect to letters of credit; (iv) all
indebtedness of others of the type referred to in the preceding clauses (i) and
(iii) assumed by or guaranteed in any manner by CMS Energy or in effect
guaranteed by CMS Energy; or (v) renewals, extensions or refundings of any of
the indebtedness referred to in the preceding clauses (i), (ii), (iii) and (iv)
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 Debentures.
(Section 12.1)
 
     The Subordinated Debt Indenture does not limit the aggregate amount of
Senior Indebtedness that may be issued. As of May 31, 1997, Senior Indebtedness
of CMS Energy aggregated approximately $1,612 million.
 
     CERTAIN COVENANTS
 
     If Subordinated Debentures are issued to a Trust or a trustee of such Trust
in connection with the issuance of Preferred Securities by such Trust, CMS
Energy will covenant that it will not, and it will not cause any of its
subsidiaries to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
CMS Energy's capital stock or (ii) make any payment of principal, interest or
premium, if any, on or repay or repurchase or redeem any debt securities
(including guarantees of indebtedness for money borrowed) of CMS Energy that
rank pari passu with or junior to the Subordinated Debentures (other than (a)
any dividend, redemption, liquidation, interest, principal or guarantee payment
by CMS Energy where the payment is made by way of securities (including capital
stock) that rank pari passu with or junior to the securities on which such
dividend, redemption, interest, principal or guarantee payment is being made,
(b) payments under the Preferred Securities Guarantee, (c) purchases of CMS
Energy Common Stock related to the issuance of CMS Energy Common Stock under any
of CMS Energy's benefit plans for its directors, officers or employees, (d) as a
result of a reclassification of CMS Energy's capital stock or the exchange or
conversion of one series or class of CMS Energy's capital stock for another
series or class of CMS Energy's capital stock and (e) the purchase of fractional
interests in shares of CMS Energy's capital stock pursuant to the conversion or
exchange provisions of such capital stock or the security being converted or
exchanged) if at such time (i) there shall have occurred any event of which CMS
Energy has actual knowledge that (a) with the giving of notice or the lapse of
time, or both, would constitute an Event of Default and (b) in respect of which
CMS Energy shall not have taken reasonable steps to cure, (ii) CMS Energy shall
be in default with respect to its payment of any obligations under the Preferred
Securities Guarantee or (iii) CMS Energy shall have given notice of its
selection of an Extension Period as provided in the Subordinated Debt Indenture
with respect to the Subordinated Debentures and shall not have rescinded such
notice, or such Extension Period, or any extension thereof, shall be continuing.
CMS Energy will also covenant (i) for so long as Preferred Securities are
outstanding, not to convert the Subordinated Debentures except pursuant to a
notice of conversion delivered to the Conversion Agent by a holder of Preferred
Securities, (ii) to maintain directly or indirectly 100% ownership of the Common
Securities, provided that certain successor which are permitted pursuant to the
Subordinated Debt Indenture may succeed to CMS Energy's ownership of the Common
Securities, (iii) not to voluntarily terminate, wind-up or liquidate such Trust,
except (a) in connection with a distribution of the Subordinated Debentures to
the holders of the Preferred Securities in liquidation of such Trust or (b) in
connection with certain mergers, consolidations or amalgamations permitted by
the Trust Agreement, (iv) to maintain the reservation for issuance of the number
of shares of CMS Energy Common Stock that would be required from time to time
upon the conversion of all the Subordinated Debentures then outstanding, (v) to
use its reasonable efforts, consistent with the terms and provisions of the
Trust Agreement, to cause such
 
                                       16

Trust to remain classified as a grantor trust and into as an association taxable
as a corporation for United States federal income tax purposes and (vi) to
deliver shares of CMS Energy Common Stock upon an election by the holders of the
Preferred Securities to convert such Preferred Securities into CMS Energy Common
Stock. (Section 3.5).
 
     As part of the Preferred Securities Guarantee, CMS Energy will agree that
it will honor all obligations described therein relating to the conversion or
exchange of the Preferred Securities into or for CMS Energy Common Stock or
Subordinated Debentures.
 
     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 Debentures 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.
(Section 9.1).
 
     CONVERSION RIGHTS
 
     If the Prospectus Supplement provides, the Holders of Subordinated
Debentures may convert the Subordinated Debentures into CMS Energy Common Stock,
as defined herein (see "Description of Securities -- Common Stock"), at the
option of the Holders at the principal amount thereof, or of such portion
thereof, at any time during the period specified in the Prospectus Supplement,
at the conversion price or conversion rate specified in the Prospectus
Supplement; except that, with respect to any Subordinated Debentures (or portion
thereof) called for redemption, such conversion right shall terminate at the
close of business on the fifteenth day prior to the date fixed for redemption of
such Subordinated Debentures, unless CMS Energy shall default in payment of the
amount due upon redemption thereof (Section 13.2).
 
     The conversion privilege and conversion price or conversion rate will be
adjusted in certain events, including if CMS Energy (i) pays a dividend or makes
a distribution in shares of CMS Energy Common Stock; (ii) subdivides its
outstanding shares of CMS Energy Common Stock into a greater number of shares;
(iii) combines its outstanding shares of CMS Energy Common Stock into a smaller
number of shares; (iv) pays a dividend or makes a distribution on its CMS Energy
Common Stock other than in shares of its CMS Energy Common Stock; (v) issues by
reclassification of its shares of CMS Energy Common Stock any shares of its
capital stock; (vi) issues any rights or warrants to all holders of shares of
its CMS Energy Common Stock entitling them (for a period expiring within 45
days, or such other period as may be specified in the Prospectus Supplement) to
purchase shares of CMS Energy Common Stock (or Convertible Securities) at a
price per share less than the Average Market Price per share for such CMS Energy
Common Stock; and (vii) distributes to all holders of shares of its CMS Energy
Common Stock any assets or Subordinated Debentures or any rights or warrants to
purchase securities, provided that no adjustment shall be made under (vi) or
(vii) above if the adjusted conversion price would be higher than, or the
adjusted conversion rate would be less than, the conversion price or conversion
rate, as the case may be, in effect prior to such adjustment (Sections 13.7,
13.8 and 13.9). CMS Energy may reduce the conversion price or increase the
conversion rate, temporarily or otherwise, by any amount but in no event shall
such adjusted conversion price or conversion rate result in shares of CMS Energy
Common Stock being issuable upon conversion of the Subordinated Debentures if
converted at the time of such adjustment at an effective conversion price per
share less than the par value of the CMS Energy Common Stock at the time such
adjustment is made. (Section 13.10) No adjustments in the conversion price or
conversion rate need be made unless the adjustment would require an increase or
decrease of at least one percent (1%) in the initial conversion price or
conversion rate. Any adjustment which is not made shall be carried forward and
taken into account in any subsequent adjustment (Section 13.13). The foregoing
conversion provisions may be modified to the extent set forth in the Prospectus
Supplement.

     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 Debentures to: (a) secure the Subordinated
Debentures 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 Debentures then Outstanding, (c) add covenants
for the protection of the Holders of the Subordinated Debentures, (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 Debentures, (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. (Section
8.1)
 
     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 Debentures 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 the Subordinated Debentures 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 of the Subordinated
Debentures 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 of the Subordinated Debentures, or reduce the
principal amount thereof, or reduce the rate or change the time of payment of
interest thereon (other than any permitted deferrals of the payments of
interest), 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 of the Subordinated
Debentures when due, or materially adversely affects the subordination
provisions of the Subordinated Debt Indenture; or (b) reduce the percentage in
principal amount of the Subordinated Debentures 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, provided that, so long as any
of the Preferred Securities remain outstanding, no such modification may be made
that adversely affects the holders of such Preferred Securities in any material
respect, and no termination of the Subordinated Debt Indenture may occur, and no
waiver of any Event of Default or compliance with any covenant under the
Subordinated Debt Indenture may be effective, without the prior consent of the
holders of at least a majority in aggregate liquidation amount of the Preferred
Securities then outstanding unless and until the principal of the Subordinated
Debentures and all accrued and unpaid interest thereon has been paid in full.
(Section 8.2)
 
     Prior to the acceleration of the maturity of any Subordinated Debentures,
the Holders of a majority in aggregate principal amount of the Subordinated
Debentures 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 Debentures
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 Debentures which cannot be
modified or amended without the consent of the Holder of each of the
Subordinated Debentures affected. (Section 5.10)
 
     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 Debentures of a particular series then Outstanding (except for
certain obligations to register the transfer of or exchange the Subordinated
Debentures of such series, to replace stolen, lost or mutilated
 
                                       18
<PAGE>   31
 
Subordinated Debentures 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 Subordinated Debt Indenture (including
those described under "Consolidation, Merger or Sale of Assets") 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 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
Debentures of such series on the stated maturity of such Subordinated Debentures
(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 Debentures 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 Subordinated Debt
Indenture there has been a change in the applicable Federal income tax law.
(Section 10.1)
 
     In the event CMS Energy exercises its option to effect a covenant
defeasance with respect to the Subordinated Debentures of any series as
described in the preceding paragraph and the Subordinated Debentures 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 Debentures 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 Debentures then Outstanding (except for certain
obligations to register the transfer of or exchange such Subordinated Debentures
to replace stolen, lost or mutilated Subordinated Debentures, 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 Debentures on the stated maturities
thereof (including one or more redemption dates), provided that such
Subordinated Debentures are by their terms due and payable, or are to be called
for redemption, within one year. (Section 10.1)
 
     For United States Federal income tax purposes any deposit contemplated in
the preceding paragraph would be treated as an exchange of the Subordinated
Debentures outstanding for other property. Accordingly, holders of Subordinated
Debentures 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.

PREFERRED SECURITIES
 
     GENERAL
 
     Each CMS Energy Trust may issue, from time to time, Preferred Securities
having terms described in the Prospectus Supplement relating thereto. The Trust
Agreement of each Trust will authorize the establishment of no more than one
series of Preferred Securities, having such terms, including distributions,
redemption, voting, liquidation rights and such other preferred, deferred or
other special rights or such rights or restrictions as shall be set forth
therein or otherwise established by the Trust Trustees pursuant thereto.
Reference is made to the Prospectus Supplement relating to the Preferred
Securities for specific terms, including (i) the distinctive designation and the
number of Preferred Securities to be offered which will represent undivided
beneficial interests in the assets of the Trust; (ii) the annual distribution
rate and the dates or date upon which such distributions will be paid, provided,
however distributions on the Preferred Securities will be paid quarterly in
arrears to holders of Preferred Securities as of a record date on which the
Preferred Securities are outstanding; (iii) whether holders' can convert the
Preferred Securities into shares of CMS Energy Common Stock; (iv) whether
distributions on Preferred Securities would be deferred during any deferral of
interest payments on the Subordinated Debentures, provided, however that no such
deferral, including extensions, if any, may exceed 20 consecutive quarters nor
extend beyond the stated maturity date of the Subordinated Debentures, and at
the end of any such deferrals, CMS Energy shall make all interest payments then
accrued or deferred and unpaid (including any compounded interest); (v) the
amount of any liquidation preference; (vi) the obligation, if any, of the Trust
to redeem Preferred Securities through the exercise of CMS Energy of an option
on the corresponding Subordinated Debenture and the price or prices at which,
the period or periods within which and the terms and conditions upon which
Preferred Securities shall be purchased or redeemed, in whole or in part,
pursuant to such obligation; (vii) the period or periods within which and the
terms and conditions, if any, including the price or prices or the rate or rates
of conversion or exchange and the terms and conditions of any adjustments
thereof, upon which the Preferred Securities shall be convertible or
exchangeable at the option of the holder of the Preferred Securities or other
property or cash; (viii) the voting rights, if any, of the Preferred Securities
in addition to those required by law and in the Trust Agreement, or set forth
under the Guarantees (as defined below); (ix) the additional payments, if any,
which the Trust will pay as a distribution as necessary so that the net amounts
reserved by the Trust and distributable to the holders of the Preferred
Securities, after all taxes, duties, assessments or governmental charges of
whatever nature (other than withholding taxes) have been paid will not be less
than the amount that would have been reserved and distributed by the Trust, and
the amount the holders of the Preferred Securities would have reserved, had no
such taxes, duties, assessments or governmental charges been imposed; (x) the
terms and conditions, if any, upon which the Subordinated Debentures may be
distributed to holders of Preferred Securities; and (xi) any other relative
rights, powers, preferences, privileges, limitations or restrictions of the
Preferred Securities not inconsistent with the Trust Agreement or applicable
law. All Preferred Securities offered hereby will be irrevocably guaranteed by
CMS Energy, on a subordinated basis and to the extent set forth below under
"Description of the Guarantees." Any applicable federal income tax
considerations applicable to any offering of the Preferred Securities will be
described in the Prospectus Supplement relating thereto. The aggregate number of
Preferred Securities which the Trust shall have authority to issue will be
pursuant to the terms of the Trust Agreement.
 
     EFFECT OF OBLIGATIONS UNDER THE SUBORDINATED DEBENTURES AND THE GUARANTEE
 
     As set forth in the Trust Agreement, the sole purpose of the Trust is to
issue the Trust securities evidencing undivided beneficial interests in the
assets of each of the Trust, and to invest the proceeds from such issuance and
sale to acquire directly the Subordinated Debentures from CMS Energy.
 
                                       20
<PAGE>   33
 
     As long as payments of interest and other payments are made when due on the
Subordinated Debentures, such payments will be sufficient to cover distributions
and payments due on the Trust securities because of the following factors: (i)
the aggregate principal amount of Subordinated Debentures will be equal to the
sums of the aggregate stated liquidation amount of the Trust securities; (ii)
the interest rate and the interest and other payment dates on the Subordinated
Debentures will match the distribution rate and distribution and other payment
dates for the Preferred Securities; (iii) CMS Energy shall pay all, and the
Trust shall not be obligated to pay, directly or indirectly, all costs,
expenses, debt and obligations of the Trust (other than with respect to the
Trust securities); and (iv) the Trust Agreement further provides that CMS Energy
Trustees shall not take or cause or permit the Trust to, among other things,
engage in any activity that is not consistent with the purposes of the Trust.
 
     Payments of distributions (to the extent funds therefore are available) and
other payments due on the Preferred Securities (to the extent funds therefor are
available) are guaranteed by CMS Energy as and to the extent set forth under
"The Guarantees" below. If CMS Energy does not make interest payments on the
Subordinated Debenture purchased by the Trust, it is expected that the Trust
will not have sufficient funds to pay distributions on the Preferred Securities.
The Guarantee does not apply to any payment of distributions unless and until
the Trust has sufficient funds for the payment of distributions and other
payments on the Preferred Securities only if and to the extent that CMS Energy
has made a payment of interest or principal on the Subordinated Debenture held
by the Trust as its sole asset. The Guarantee, when taken together with CMS
Energy's obligations under the Subordinated Debenture and the Indenture and its
obligations under the Trust Agreement, including its obligations to pay costs,
expenses, debts and liabilities of the Trust (other than with respect to the
Trust securities), provide a full and unconditional guarantee of amounts on the
Preferred Securities.
 
     If CMS Energy fails to make interest or other payments on the Subordinated
Debentures when due (taking account of any extension period), the Trust
Agreement provides a mechanism whereby the holders of the Preferred Securities
may direct the institutional Trustee to enforce its rights under the
Subordinated Debenture. If the institutional Trustee fails to enforce its rights
under the Subordinated Debentures, a holder of Preferred Securities may
institute a legal proceeding against CMS Energy to enforce the institutional
Trustee's rights under the Subordinated Debentures without first instituting any
legal proceeding against the institutional Trustee or any other person or
entity. Notwithstanding the foregoing, if an event of default has occurred and
is continuing under the Trust Agreement, and such event is attributable to the
failure of CMS Energy to pay interest or principal on the Subordinated
Debentures on the date such interest or principal is otherwise payable (or in
the case of redemption on the redemption date), then a holder of Preferred
Securities may institute legal proceedings directly against CMS Energy to obtain
payment. If CMS Energy fails to make payments under the Guarantee, the Guarantee
provides a mechanism whereby the holders of the Preferred Securities may direct
the Guarantee trustee to enforce its rights thereunder. Any holder of Preferred
Securities may institute a legal proceeding directly against CMS Energy to
enforce the Guarantee trustee's rights under the Guarantee without first
instituting a legal proceeding against the Trust, the Preferred Guarantee
Trustee, or any other person or entity.
 
THE GUARANTEES
 
     Set forth below is a summary of information concerning the Preferred
Securities Guarantee (each, the "Guarantee") which will be executed and
delivered by CMS Energy for the benefit of the holders, from time to time, of
the Preferred Securities. The Preferred Securities Guarantee will be qualified
as an indenture under the Trust Indenture Act of 1939. The Bank of New York, an
independent trustee, will act as indenture trustee under the Preferred
Securities Guarantee for purpose of compliance with the provisions of the Trust
Indenture Act of 1939. The summary does not purport to be complete and is
subject in all respects to the provisions of, and is qualified in its
 
                                       21
<PAGE>   34
 
entirety by reference to, the Guarantee, which are filed as an exhibit to the
Registration Statement of which this Prospectus forms a part.
 
     GENERAL
 
     CMS Energy will irrevocably agree to pay in full on a subordinated basis,
to the extent set forth herein, the Guarantee Payments (as defined below) to the
holders of the Preferred Securities, as and when due, regardless of any defense,
right of set-off or counterclaim that the Trust may have or assert other than
the defense of payment. The following payments with respect to the Preferred
Securities, to the extent not paid by or on behalf of the Trust (the "Guarantee
Payments"), will be subject to the Guarantee: (i) any accumulated and unpaid
distributions required to be paid on the Preferred Securities, to the extent
that the Trust has funds on hand available therefor at such time, (ii) the
redemption price with respect to any Preferred Securities called for redemption
to the extent that the Trust has funds on hand available therefor at such time,
or (iii) upon a voluntary or involuntary dissolution, winding up or liquidation
of the Trust (unless the Subordinated Debentures are distributed to holders of
the Preferred Securities), the lesser of (a) the liquidation distribution, to
the extent that the Trust has funds on hand available therefor at such time, and
(b) the amount of assets of the Trust remaining available for distribution to
holders of Preferred Securities. CMS Energy's obligation to make a Guarantee
Payment may be satisfied by direct payment of the required amounts of CMS Energy
to the holders of the Preferred Securities or by causing the Trust to pay such
amount to such holders.
 
     The Guarantee will be an irrevocable guarantee on a subordinated basis of
the Trust's obligations under the Preferred Securities, but will apply only to
the extent that the Trust has funds sufficient to make such payments, and is not
a guarantee of collection. If CMS Energy does not make interest payments on the
Subordinated Debentures held by the Trust, the Trust will not be able to pay
distributions on the Preferred Securities and will not have funds legally
available therefor.
 
     CMS Energy has, through the Guarantee, the Trust Agreement, the
Subordinated Debentures, the Subordinated Debt Indenture and the Expense
Agreement, taken together, fully, irrevocably and unconditionally guaranteed all
of the Trust's obligations under the Preferred Securities. No single document
standing alone or operating in conjunction with fewer than all of the other
documents constitutes such guarantee. It is only the combined operation of these
documents that has the effect of providing a full, irrevocable and unconditional
guarantee of the Trust's obligations under the Preferred Securities.
 
     CMS Energy has also agreed separately to irrevocably and unconditionally
guarantee the obligations of the Trust with respect to the Common Securities to
the same extent as the Guarantee, except that upon the occurrence and during the
continuation of a Trust Agreement Event of Default, holders of Preferred
Securities shall have priority over holders of Common Securities with respect to
distributions and payments on liquidation, redemption or otherwise.
 
     CERTAIN COVENANTS OF CMS ENERGY
 
     CMS Energy will covenant in the Guarantee that if and so long as (i) the
Trust is the holder of all the Subordinated Debentures, (ii) a Tax Event in
respect of the Trust has occurred and is continuing and (iii) CMS Energy has
elected, and has not revoked such election, to pay Additional Sums in respect of
the Preferred Securities and Common Securities, CMS Energy will pay to the Trust
such Additional Sums. CMS Energy will also covenant that it will not, and it
will not cause any of its subsidiaries to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of CMS Energy's capital stock or (ii) make any payment of
principal, interest or premium, if any, on or repay or repurchase or redeem any
debt securities (including guarantees of indebtedness for money borrowed) of CMS
Energy that rank pari passu with or junior to the Subordinated Debentures (other
than (a) any dividend, redemption, liquidation, interest, principal or guarantee
payment by CMS Energy where the payment
 
                                       22
<PAGE>   35
 
is made by way of securities (including capital stock) that rank pari passu with
or junior to the securities on which such dividend, redemption, interest,
principal or guarantee payment is being made, (b) payments under the Guarantee,
(c) purchases of CMS Energy Common Stock related to the issuance of CMS Energy
Common Stock under any of CMS Energy's benefit plans for its directors, officers
or employees, (d) as a result of a reclassification of CMS Energy's capital
stock or the exchange or conversion of one series or class of CMS Energy's
capital stock for another series or class of CMS Energy's capital stock and (e)
the purchase of fractional interests in shares of CMS Energy's capital stock
pursuant to the conversion or exchange provisions of such capital stock or the
security being converted or exchanged) if at such time (i) there shall have
occurred any event of which CMS Energy has actual knowledge that (a) with the
giving of notice or the lapse of time, or both, would constitute a Subordinated
Debenture Event of Default and (b) in respect of which CMS Energy shall not have
taken reasonable steps to cure, (ii) CMS Energy shall be in default with respect
to its payment of any obligations under the Guarantee or (iii) CMS Energy shall
have given notice of its selection of an Extension Period as provided in the
Subordinated Debt Indenture with respect to the Subordinated Debentures and
shall not have rescinded such notice, or such Extension Period, or any extension
thereof, shall be continuing. CMS Energy also covenant (i) for so long as
Preferred Securities are outstanding, not to convert Subordinated Debentures
except pursuant to a notice of conversion delivered to the Conversion Agent by a
holder of Preferred Securities, (ii) to maintain directly or indirectly 100%
ownership of the Common Securities, provided that certain successors which are
permitted pursuant to the Subordinated Debt Indenture may succeed to CMS
Energy's ownership of the Common Securities, (iii) not to voluntarily terminate,
wind-up or liquidate the Trust, except (a) in connection with a distribution of
the Debentures to the holders of the Preferred Securities in liquidation of the
Trust or (b) in connection with certain mergers, consolidations or amalgamations
permitted by the Trust Agreement, (iv) to maintain the reservation for issuance
of the number of shares of CMS Energy Common Stock that would be required from
time to time upon the conversion of all the Subordinated Debentures then
outstanding, (v) to use its reasonable efforts, consistent with the terms and
provisions of the Trust Agreement, to cause the Trust to remain classified as a
grantor trust and not as an association taxable as a corporation for United
States federal income tax purposes and (vi) to deliver shares of CMS Energy
Common Stock upon an election by the holders of the Preferred Securities to
convert such Preferred Securities into CMS Energy Common Stock.
 
     As part of the Guarantee, CMS Energy will agree that it will honor all
obligations described therein relating to the conversion or exchange of the
Preferred Securities into or for CMS Energy Common Stock or Subordinated
Debentures.
 
     AMENDMENTS AND ASSIGNMENT
 
     Except with respect to any changes which do not materially adversely affect
the rights of holders of the Preferred Securities (in which case no vote will be
required), the Guarantee may not be amended without the prior approval of the
holders of not less than a majority in aggregate liquidation amount of such
outstanding Preferred Securities. All guarantees and agreements contained in the
Guarantee shall bind the successors, assigns, receivers, trustees and
representatives of CMS Energy and shall inure to the benefit of the holders of
the Preferred Securities then outstanding.
 
     TERMINATION OF THE GUARANTEE
 
     The Guarantee will terminate and be of no further force and effect upon
full payment of the redemption price of the Preferred Securities, upon full
payment of the amounts payable upon liquidation of the Trust, upon the
distribution, if any, of CMS Energy Common Stock to the holders of Preferred
Securities in respect of the conversion of all such holders' Preferred
Securities into CMS Energy Common Stock or upon distribution of the Subordinated
Debentures to the holders of the Preferred Securities in exchange for all of the
Preferred Securities. The Guarantee will continue to
 
                                       23
<PAGE>   36
 
be effective or will be reinstated, as the case may be, if at any time any
holder of Preferred Securities must restore payment of any sums paid under such
Preferred Securities or the Guarantee.
 
     EVENTS OF DEFAULT
 
     An event of default under the Guarantee will occur upon the failure of CMS
Energy to perform any of its payment or other obligations thereunder. The
holders of a majority in aggregate liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of the
Guarantee or to direct the exercise of any trust or power conferred upon the
Guarantee Trustee under the Guarantee.
 
     If the Guarantee Trustee fails to enforce the Guarantee, any holder of the
Preferred Securities may institute a legal proceeding directly against CMS
Energy to enforce its rights under the Guarantee without first instituting a
legal proceeding against the Trust, the Guarantee Trustee or any other person or
entity. In addition, any record holder of Preferred Securities shall have the
right, which is absolute and unconditional, to proceed directly against CMS
Energy to obtain Guarantee Payments, without first waiting to determine if the
Guarantee Trustee has enforced the Guarantee or instituting a legal proceeding
against the Trust, the Guarantee Trustee or any other person or entity. CMS
Energy has waived any right or remedy to require that any action be brought just
against the Trust, or any other person or entity before proceeding directly
against CMS Energy.
 
     CMS Energy, as guarantor, is required to file annually with the Guarantee
Trustee a certificate as to whether or not CMS Energy is in compliance with all
the conditions and covenants applicable to it under the Guarantee.
 
     STATUS OF THE GUARANTEE
 
     The Guarantee will constitute an unsecured obligation of CMS Energy and
will rank subordinate and junior in right of payment to all other liabilities of
CMS Energy and will rank pari passu with any guarantee now or hereafter entered
into by CMS Energy in respect of any preferred or preference stock of any
affiliate of CMS Energy.
 
     The Guarantee will constitute a guarantee of payment and not of collection
(i.e., the guaranteed party may institute a legal proceeding directly against
the Guarantor to enforce its rights under the Guarantee without first
instituting a legal proceeding against any other person or entity). The
Guarantee will be held for the benefit of the holders of the Preferred
Securities. The Guarantee will not be discharged except by payment of the
Guarantee Payments in full to the extent not paid by the Trust or upon
distribution of the Subordinated Debentures to the holders of the Preferred
Securities. The Guarantee does not place a limitation on the amount of
additional indebtedness that may be incurred by CMS Energy or any of its
subsidiaries.
 
DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS
 
     CMS Energy may issue Stock Purchase Contracts, representing contracts
obligating holders to purchase from CMS Energy, and CMS Energy to sell to the
holders, a specified number of shares of CMS Energy Common Stock at a future
date or dates. The price per share of CMS Energy Common Stock may be fixed at
the time the Stock Purchase Contracts are issued or may be determined by
reference to a specific formula set forth in the Stock Purchase Contracts. The
Stock Purchase Contracts may require CMS Energy to make periodic payments to the
holders of the Stock Purchase Units or visa versa, and such payments may be
unsecured or refunded on some basis. The Stock Purchase Contracts may require
holders to secure their obligations thereunder in a specified manner.
 
     The applicable Prospectus Supplement will describe the terms of any Stock
Purchase Contracts or Stock Purchase Units. The description in Prospectus
Supplement will not purport to be complete
 
                                       24

and will be qualified in its entirety by reference to the Stock Purchase
Contracts, and, if applicable, collateral arrangements and depositary
arrangements, relating to such Stock Purchase Contracts or Stock Purchase Units.
 
                                 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 matters of Delaware law relating to the validity
of the Preferred Securities will be passed upon on behalf of the Trusts by
special Delaware counsel to the Trusts, who will be named in the Prospectus
Supplement. Certain United States federal income taxation matters may be passed
upon for CMS Energy and the Trust by special tax counsel to CMS Energy and of

                                    EXPERTS
 
     The consolidated financial statements and schedule of CMS Energy as of
December 31, 1996 and 1995, and for each of the three years in the period ended
December 31, 1996 incorporated by reference in this Prospectus, have been
audited by Arthur Andersen LLP (formerly Arthur Andersen & Co.), 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 period ended March 31, 1997 and 1996, 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 reports 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 of 1933, as amended
("Securities Act"), for their reports on the unaudited interim consolidated
financial information because these reports are not "reports" 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
