(1)   There are being registered hereunder such presently indeterminate
      principal amount or number of shares of CMS Energy Corporation Common
      Stock, Senior Debentures, Subordinated Debentures, Stock Purchase
      Contracts and Stock Purchase Units, as well as Trust Preferred Securities
      of CMS Energy Trust IV and CMS Energy Trust V and Guarantees thereof, as
      may from time to time be issued at indeterminate prices, plus additional
      shares of CMS Energy Corporation Common Stock into which such Subordinated
      Debentures or Trust Preferred Securities may be converted.

(2)   Estimated solely for the purpose of calculating the registration fee.
      Pursuant to Rule 457(o) under the Securities Act of 1933 which permits the
      registration fee to be calculated on the basis of the maximum offering
      price of all the securities listed, the table does not specify by each
      class information as to the amount to be registered, proposed maximum
      offering price per unit or proposed maximum aggregate offering price.

(3)   Exclusive of accrued interest and distributions, if any.

(4)   The Subordinated Debentures may be purchased by, and constitute assets of,
      CMS Energy Trust IV or CMS Energy Trust V, and may later be distributed
      under certain circumstances to holders of Trust Preferred Securities.
      Additionally, CMS Energy Corporation Common Stock may be issued upon
      conversion of any convertible Subordinated Debentures. In either case, no
      additional consideration will be received.

(5)   The Trust Preferred Securities may be convertible into the Subordinated
      Debentures, which may be convertible into shares of CMS Energy Corporation
      Common Stock. In addition, the Trust Preferred Securities may be directly
      convertible into shares of CMS Energy Corporation Common Stock. Shares of
      CMS Energy Corporation Common Stock issued upon conversion of the
      Subordinated Debentures or Trust Preferred Securities will be issued
      without the payment of additional consideration.

(6)   The registration statement is deemed to include the obligations of CMS
      Energy Corporation under the Guarantee (as defined herein) and certain
      backup undertakings under: (1) the subordinated debt indenture (as
      described herein) pursuant to which the Subordinated Debentures will be
      issued; (2) the Subordinated Debentures; and (3) the Declaration of Trust
      of CMS Energy Trust IV and CMS Energy Trust V, including CMS Energy
      Corporation's obligations under such indenture to pay costs, expenses,
      debts and liabilities of the applicable Trust (other than with respect to
      the Trust Preferred Securities and the Common Securities of CMS Energy
      Trust IV or CMS Energy Trust V), which taken together provide a full and
      unconditional guarantee of amounts due on the Trust Preferred Securities.
      No separate consideration will be received for the Guarantee and such
      backup undertakings. The Guarantee is not traded separately.

(7)   Includes a presently indeterminate number of shares of CMS Energy
      Corporation Common Stock to be issuable by CMS Energy Corporation upon
      settlement of the Stock Purchase Contracts or Stock Purchase Units issued
      by CMS Energy Corporation.

(8)   A portion of the registration fee has been previously paid. Prior to the
      filing of this registration statement, $15,997,500 aggregate principal
      amount of securities remained registered and unsold, pursuant to
      Registration Statement No. 333-51932, which was initially filed by the
      registrants on December 15, 2000. Pursuant to Rule 457(p), the applicable
      portion of the registration fee of $4,223 associated with such unsold
      securities has been offset against the registration fee of $176,550
      associated with the securities to be registered under this registration
      statement and such unsold securities are hereby deregistered.

      THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL
FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION
STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(a) OF
THE SECURITIES ACT OF 1933 OR UNTIL THIS REGISTRATION STATEMENT SHALL BECOME
EFFECTIVE ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID SECTION 8(a),
MAY DETERMINE.


      The information in this prospectus is not complete and may be changed. We
may not sell these securities until the registration statement filed with the
Securities and Exchange Commission is effective. This prospectus is not an offer
to sell these securities and it is not soliciting an offer to buy these
securities in any state where the offer or sale is not permitted.

                                     SUMMARY

      This prospectus is part of a registration statement on Form S-3 that we
filed with the Securities and Exchange Commission (the "SEC") utilizing a
"shelf" registration process. Under this shelf process, we may sell any
combination of securities described in this prospectus in one or more offerings,
up to a total dollar amount of $1,500,000,000. This prospectus provides you with
a general description of the securities we may offer. Each time we sell
securities, we will provide a prospectus supplement containing specific
information about the terms of that offering. The prospectus supplement may also
add, update or change information contained in this prospectus. You should read
both this prospectus and any prospectus supplement together with additional
information described below under the heading "Where To Find More Information."
Our principal executive offices are located at One Energy Plaza, Jackson,
Michigan 49201. The telephone number is 517-788-0550.

                                  RISK FACTORS

      Before acquiring any of the securities that may be offered hereby, you
should carefully consider the risks discussed in the section of our Form 10-Q,
filed May 5, 2005, for the quarter year ended March 31, 2005, entitled
"Forward-Looking Statements and Risk Factors," which is incorporated in this
document by reference. You should also consider the risk factors listed in the
accompanying prospectus supplement or supplements and you should read this
prospectus and the accompanying prospectus supplement or supplements carefully
before you invest.

                         WHERE TO FIND MORE INFORMATION

      We file reports, proxy statements and other information with the SEC under
File No. 1-9513. Our SEC filings are also available over the Internet at the
SEC's Web site at http://www.sec.gov. You may also read and copy any document we
file at the SEC's public reference room at 450 Fifth Street N.W., Room 1024,
Washington D.C. 20549. Please call the SEC at 1-800-SEC-0330 for more
information on the SEC's public reference room and its copy charges. Since we
have securities listed on the New York Stock Exchange, you may also inspect our
SEC reports and other information at the New York Stock Exchange, 20 Broad
Street, New York, New York 10005. You can find additional information about us,
including our Annual Report on Form 10-K for the year ended December 31, 2004
and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2005, on
our Web site at http://www.cmsenergy.com. The information on this Web site is
not a part of this prospectus.

      We have not included separate financial statements of the Trusts. We and
the Trusts do not consider that such financial statements would be material to
holders of Trust Preferred Securities because each Trust is a special purpose
entity, has no operating history and no independent operations. The Trusts are
not currently involved in and don't anticipate being involved in any activity
other than as described under "CMS Energy Trusts." Further, we believe that
financial statements of the Trusts are not material to the holders of the Trust
Preferred Securities since we will guarantee the Trust Preferred Securities.
Holders of the Trust 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 Corporation ("CMS
Energy") as a preferred stockholder of CMS Energy. We beneficially own all of
the undivided beneficial interests in the assets of the Trusts (other than the
beneficial interests represented by the Trust Preferred Securities). See "CMS
Energy Trusts," "Description of Securities -- Trust Preferred Securities" and
"Effect of Obligations Under the Debt Securities And the Guarantees -- The
Guarantees." In future filings under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), there will be an audited footnote to our annual
financial statements stating that the Trusts are wholly-owned by CMS Energy,
that the sole assets of the Trusts are the Senior Debentures or 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 Trust Preferred Securities issued by the Trusts.

      We are "incorporating by reference" information into this prospectus. This
means that we are disclosing important information to you when we refer you to
another document that we filed separately with the SEC. Information incorporated
by reference is considered to be part of this prospectus, unless the information
is updated by information in this prospectus. This prospectus incorporates by
reference the documents listed below. We encourage you to read these additional
documents because these documents contain important information about us and our
finances.

                             CMS ENERGY CORPORATION

      We are an integrated energy company with a business strategy focused
primarily in Michigan. We are the parent holding company of Consumers Energy
Company ("Consumers") and CMS Enterprises Company ("Enterprises"). Consumers is
a combination electric and gas utility company serving Michigan's Lower
Peninsula. Enterprises, through various subsidiaries and equity investments, is
engaged in domestic and international diversified energy businesses. We manage
our businesses by the nature of services each provides and operate principally
in three business segments: electric utility, gas utility, and enterprises.

                                CMS ENERGY TRUSTS

      CMS Energy Trust IV and CMS Energy Trust V are statutory business trusts
formed under the Delaware Business Trust Act (the "Trust Act") (each, a "Trust"
and collectively, the "Trusts") pursuant to: (i) a trust agreement executed by
CMS Energy, as sponsor, and the trustees of the Trusts (the "CMS Trustees"); and
(ii) the filing of a certificate of trust with the Secretary of State of the
State of Delaware. At the time of public issuance of Trust Preferred Securities,
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 (the
"Common Securities" and, together with the Trust Preferred Securities, the
"Trust Securities") in an aggregate liquidation amount equal to approximately 3%
for the total capital of the Trust. Each Trust exists for the exclusive purposes
of:

      -     issuing the Trust Preferred Securities and Common Securities
            representing undivided beneficial interests in the assets of the
            Trust;

      -     investing the gross proceeds of the Trust Securities in the Senior
            Debentures or Subordinated Debentures; and

      -     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.

      The undivided common beneficial interests in the Trust will be owned by
CMS Energy. The proceeds from the offering of the Trust Preferred Securities and
the sale of the Common Securities may be contributed by the Trust to purchase
from CMS Energy Senior Debentures or Subordinated Debentures in an aggregate
principal amount equal to the aggregate liquidation preference of the Trust
Securities, bearing interest at an annual rate equal to the annual distribution
rate of such Trust Securities and having certain redemption terms which
correspond to the redemption terms for the Trust Securities. The Senior
Debentures will rank on an equal basis with all other unsecured debt of CMS
Energy except subordinated debt. The Subordinated Debentures will rank
subordinate in right of payment to all of CMS Energy's Senior Indebtedness (as
defined herein). Distributions on the Trust Securities may not be made unless
the Trust receives corresponding interest payments on the Senior Debentures or
the Subordinated Debentures from CMS Energy. CMS Energy will irrevocably
guarantee, on a senior or subordinated basis, as applicable, and to the extent
set forth therein, with respect

                                       4


to each of the Trust Securities, 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 Guarantee will be
unsecured and will be either equal to or subordinate to, as applicable, 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 Trust Securities
could receive Senior Debentures or Subordinated Debentures in lieu of any
liquidating cash distribution.

      Pursuant to the Trust Agreement, the number of CMS Trustees will initially
be three. Two of the CMS Trustees will be persons who are employees or officers
of or who are affiliated with CMS Energy (the "Administrative Trustees"). 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, either The Bank of
New York, a New York banking corporation, or J.P. Morgan Trust Company, N.A., a
national banking association, 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 or J.P.
Morgan Trust Company, N.A. will also act as trustee (each a "Guarantee Trustee"
and collectively the "Guarantee Trustees"). The Bank of New York (Delaware) will
act as the "Delaware Trustee" for the purposes of the Trust Act, until removed
or replaced by the holder of the Common Securities. See "Effect of Obligations
Under the Debt Securities And the Guarantees -- The Guarantees."

      Each Property Trustee will hold title to the applicable Debt Securities
for the benefit of the holders of the Trust Securities and each Property Trustee
will have the power to exercise all rights, powers and privileges under the
applicable indentures (as defined herein) as the holder of the Debt Securities.
In addition, each 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 Debt Securities for the benefit of the
holders of the Trust Securities. Each 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 Trustees will hold the Guarantees for the benefit of the holders of
the Trust 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
the Trusts and the offering of the Trust Securities.

      The rights of the holders of the Trust 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, One Energy Plaza, Jackson, Michigan 49201.

                                 USE OF PROCEEDS

      The proceeds received by each of the Trusts from the sale of its Trust
Preferred Securities or the Common Securities will be invested in the Senior
Debentures or the Subordinated Debentures. As will be more specifically set
forth in the applicable prospectus supplement, we will use such borrowed amounts
and the net proceeds from the sale of CMS Energy Common Stock, Stock Purchase
Contracts, Stock Purchase Units and any Senior Debentures or Subordinated
Debentures offered hereby for our general corporate purposes, including capital
expenditures, investment in subsidiaries, working capital and repayment of debt.

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, which are
incorporated into this prospectus by reference. See "Where You Can Find More

                                       7

COMMON STOCK

DIVIDEND RIGHTS AND POLICY; RESTRICTIONS ON DIVIDENDS

      Dividends on the common stock are paid at the discretion of the Board of
Directors based primarily upon the earnings and financial condition of CMS
Energy. Dividends are payable out of the assets of CMS Energy legally available
therefor.

      In January 2003, the Board of Directors suspended the payment of CMS
Energy Common Stock dividends.

      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),
borrowings and sales of equity. CMS Energy's ability to pay dividends on CMS
Energy Common Stock is dependent primarily upon the earnings and cash flows of
its subsidiaries and the distribution or other payment of such earnings to CMS
Energy in the form of dividends, tax sharing payments, loans or advances and
repayment of loans and advances from CMS Energy. 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 capital stock of CMS Energy or to make any
funds available therefor, whether by dividends, loans or other payments.

      Dividends on capital stock of CMS Energy are limited by Michigan law to
legally available assets of CMS Energy. Distributions on CMS Energy Common Stock
may be subject to the rights of the holders, if any, of the Preferred Stock,
including the currently issued and outstanding 4.50% Cumulative Convertible
Preferred Stock. As long as the 4.50% Cumulative Convertible Preferred Stock is
outstanding, CMS Energy may not pay dividends on the CMS Energy Common Stock
unless certain conditions are met including, but not limited to, that dividends
on the 4.50% Cumulative Convertible Preferred Stock have been paid. See
"Preferred Stock -- Dividends".

      CMS Energy is subject to the following contractual restrictions on its
ability to pay dividends:

CMS ENERGY'S SENIOR SECURED CREDIT FACILITY

      Under the terms of our Sixth Amended and Restated Credit Agreement, dated
as of May 18, 2005, we have agreed that we will not, and will not permit certain
of our subsidiaries, directly or indirectly, to:

      -     declare or pay any dividend, payment or other distribution of
            assets, properties, cash, rights, obligations or securities on
            account of any shares of any class of CMS Energy Common Stock or the
            capital stock or other ownership interests of certain subsidiaries
            (other than stock splits and dividends payable solely in our
            non-convertible equity securities (other than Redeemable Stock or
            Exchangeable Stock (as such terms are defined in the senior debt
            indenture on May 18, 2005)) and dividends and distributions made to
            us or certain of our subsidiaries); or

      -     purchase, redeem, retire or otherwise acquire for value any such
            capital stock or other ownership interests;

other than (i) pursuant to the terms of any class of our capital stock issued
and outstanding (and as in effect on May 18, 2005), any purchase or redemption
of our capital stock made by exchange for, or out of the proceeds of the
substantially concurrent sale of, our capital stock (other than Redeemable Stock
or Exchangeable Stock (as such terms are defined in the senior debt indenture on
May 18, 2005)), (ii) payments made by us or certain subsidiaries pursuant to our
tax sharing agreement and (iii) after January 1, 2005, payments not to exceed
certain amounts for any twelve-month period so long as a certain amount of
liquidity is held by CMS Energy.

SENIOR DEBT INDENTURE

      Under the terms of the senior debt indenture we have the following issued
and outstanding securities: 9.875% Senior Notes Due 2007, 8.9% Senior Notes Due
2008, 7.5% Senior Notes Due 2009, 7.75% Senior Notes Due 2010, 8.5% Senior Notes
Due 2011, 6.30% Senior Notes Due 2012, 3.375% Convertible Senior Notes Due 2023,
and 2.875% Convertible Senior Notes Due 2024. So long as any of such notes
issued thereunder are outstanding and until those notes are rated BBB- or above
(or an equivalent rating) by S&P and one other rating agency, at which time we
will be permanently released from the provisions of this limitation, we have
agreed that we will not, and will not permit any of our restricted subsidiaries,
directly or indirectly, to:

      -     declare or pay any dividend or make any distribution on our capital
            stock to the direct or indirect holders of our capital stock (except
            dividends or distributions payable solely in our non-convertible
            capital stock (as defined in the senior debt

                                       8


            indenture) or in options, warrants or other rights to purchase such
            non-convertible capital stock and except dividends or other
            distributions payable to us or one of our subsidiaries);

      -     purchase, redeem or otherwise acquire or retire for value any of our
            capital stock; or

      -     purchase, repurchase, redeem, defease or otherwise acquire or retire
            for value, prior to the scheduled maturity or scheduled repayment
            thereof, any of our subordinated indebtedness (each, for purposes of
            the senior debt indenture, a "restricted payment"),

if at the time of any restricted payment described above (1) an event of default
under the senior debt indenture (or event that with the lapse of time or giving
of notice would constitute an event of default) has occurred and is continuing,
or would occur as a result of the restricted payment, or (2) after giving effect
to any restricted payment described above, the aggregate amount of all
restricted payments made since May 6, 1997 would exceed the sum of:

      -     $100 million;

      -     100% of our consolidated net income from May 6, 1997 to the end of
            the most recent fiscal quarter ending at least 45 days prior to the
            date of the restricted payment (or, in the case of a deficit, minus
            100% of the deficit); and

      -     the aggregate net proceeds we have received for any issuance or sale
            of, or contribution with respect to, our capital stock subsequent to
            May 6, 1997.

TRUST PREFERRED SECURITIES

      In June 1997, a CMS Energy affiliated trust issued $172.5 million of 7
3/4% Convertible Quarterly Income Preferred Securities. The preferred securities
are convertible at the option of the holder into shares of CMS Energy Common
Stock 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. We may, at our
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 us and The
Bank of New York, as trustee, as amended and supplemented, and the guarantee
agreement dated June 20, 1997 between us and The Bank of New York relating to
the preferred securities of CMS Energy Trust I pursuant to which the preferred
securities and the related 7 3/4% Convertible Subordinated Debentures due 2027
were issued, we have agreed that we will not, and will not cause any of our
subsidiaries to, declare or pay any dividends or distributions on, or redeem,
purchase, acquire or make a liquidation payment with respect to, any of our
capital stock, if at such time:

      -     an event has occurred, of which we have actual knowledge, that with
            the giving of notice or the lapse of time, or both, would constitute
            an event of default and in respect of which we have not taken
            reasonable steps to cure;

      -     we are in default with respect to the payment of any obligations
            under the relevant guarantee agreement; or

      -     we have given notice of our selection of an extension period as
            provided in such indenture with respect to the subordinated
            debentures and have not rescinded such notice, or such extension
            period (or any extension thereof) is continuing.

DIVIDEND RESTRICTIONS UNDER MICHIGAN LAW

      Michigan law prohibits payment of a dividend or a repurchase of capital
stock if, after giving it effect, a corporation 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 of
Incorporation provide otherwise, the amount that would be needed, if the
corporation 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).



                                       9

VOTING RIGHTS

      Each holder of CMS Energy Common Stock is entitled to one vote for each
share of CMS Energy 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 CMS Energy Common Stock 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 CMS Energy Common Stock,
and to authorize any amendment to the Articles of Incorporation that would
increase or decrease the aggregate number of authorized shares of CMS Energy
Common Stock or alter or change the powers, preferences or special rights of the
shares of CMS Energy Common Stock 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 the shares of CMS Energy Common Stock then outstanding
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 the CMS
Energy Common Stock, either directly by amendment to the Articles of
Incorporation or indirectly by requiring the holders of the CMS Energy Common
Stock 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 common stock 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 CMS Energy Common Stock to block any such merger or amendment that
would adversely affect the powers or special rights of holders of such shares of
CMS Energy Common Stock.

PREEMPTIVE RIGHTS

      The Articles of Incorporation provide that holders of CMS Energy 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 will be entitled to receive, on a per share
basis, the assets of CMS Energy remaining for distribution to the holders of CMS
Energy Common Stock. 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 that 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 voting and liquidation
rights of shares of CMS Energy Common Stock will be appropriately adjusted so as
to avoid any dilution in aggregate voting or liquidation rights.



                                       10

EXCHANGES

      The Articles of Incorporation do not provide for either the mandatory or
optional exchange or redemption of CMS Energy Common Stock.

TRANSFER AGENT AND REGISTRAR

      CMS Energy Common Stock is transferable at Consumers Energy Company, One
Energy Plaza, Jackson, Michigan 49201. CMS Energy is the registrar and transfer
agent for CMS Energy Common Stock.

PREFERRED STOCK

      The authorized Preferred Stock may be issued without the approval of the
holders of CMS Energy 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.

4.50% CUMULATIVE CONVERTIBLE PREFERRED STOCK

      The Articles of Incorporation establish one series of preferred stock
designated as "4.50% Cumulative Convertible Preferred Stock" consisting of
5,000,000 shares with a liquidation preference of $50.00 per share (the
"Cumulative Convertible Preferred Stock"). The Cumulative Convertible Preferred
Stock ranks prior to any series of our CMS Energy Common Stock as to the payment
of dividends and distribution of assets upon dissolution, liquidation or winding
up of CMS Energy, and is convertible into shares of CMS Energy Common Stock. The
holders of the Cumulative Convertible Preferred Stock have no preemptive rights.

DIVIDENDS

      Holders of shares of Cumulative Convertible Preferred Stock will be
entitled to receive, when, as and if declared by our board of directors out of
funds legally available for payment, cumulative cash dividends at the rate per
annum of 4.50% per share on the liquidation preference thereof of $50.00 per
share (equivalent to $2.25 per annum per share). Dividends on the Cumulative
Convertible Preferred Stock will be payable quarterly on March 1, June 1,
September 1 and December 1 of each year at such annual rate, and shall
accumulate from the most recent date as to which dividends shall have been paid
or, if no dividends have been paid, from the issue date of the Cumulative
Convertible Preferred Stock, whether or not in any dividend period or periods
there have been funds legally available for the payment of such dividends.
Accumulated unpaid dividends accrue and cumulate dividends at the annual rate of
4.50%.

      As long as any Cumulative Convertible Preferred Stock is outstanding, we
may not pay dividends or distributions on, or purchase, redeem or otherwise
acquire, subject to certain exceptions, shares of the CMS Energy Common Stock
unless all accumulated and unpaid dividends on the Cumulative Convertible
Preferred Stock have been paid or set aside for payment.

LIQUIDATION PREFERENCE

      In the event of our voluntary or involuntary liquidation, winding-up or
dissolution, holders of Cumulative Convertible Preferred Stock will be entitled
to receive and to be paid out of our assets available for distribution to our
stockholders, before any payment or distribution is made to holders of junior
stock (including CMS Energy Common Stock), a liquidation preference in the
amount of $50.00 per share of Cumulative Convertible Preferred Stock, plus
accumulated and unpaid dividends on the shares to the date fixed for
liquidation, winding-up or dissolution. If, upon our voluntary or involuntary
liquidation, winding-up or dissolution, the amounts payable with respect to the
liquidation preference of the Cumulative Convertible Preferred Stock and all
parity stock are not paid in full, the holders of the Cumulative Convertible
Preferred Stock and the parity stock will share equally and ratably in any
distribution of our assets in proportion to the full liquidation preference and
accumulated and unpaid dividends to which they are entitled.

                                       11


VOTING RIGHTS

      Except as required by Michigan law and our Articles of Incorporation, the
holders of Cumulative Convertible Preferred Stock have no voting rights unless
dividends payable on the Cumulative Convertible Preferred Stock are in arrears
for six or more quarterly periods (whether or not consecutive). In that event,
the holders of the Cumulative Convertible Preferred Stock, voting as a single
class with the shares of any other preferred stock or preference securities
having similar voting rights that are exercisable, will be entitled at the next
regular or special meeting of our stockholders to elect two additional directors
(or one director if fewer than six directors comprise our board prior to
appointment) and the number of directors that comprise our board will be
increased by the number of directors so elected. These voting rights and the
terms of the directors so elected will continue until such time as the dividend
arrearage on the Cumulative Convertible Preferred Stock has been paid in full.

REDEMPTION

      We cannot redeem shares of the Cumulative Convertible Preferred Stock.

MANDATORY CONVERSION

      On or after December 5, 2008, we may, at our option, cause the Cumulative
Convertible Preferred Stock to be automatically converted into that number of
shares of CMS Energy Common Stock for each share of Cumulative Convertible
Preferred Stock equal to $50.00 (the liquidation preference) divided by the
applicable conversion rate. We may exercise our conversion right only if, for 20
trading days within any period of 30 consecutive trading days (including the
last trading day of such 30-day period), the closing price of the CMS Energy
Common Stock exceeds 130% of the then prevailing conversion price of the
Cumulative Convertible Preferred Stock.

CONVERSION RIGHTS

      A holder of record of Cumulative Convertible Preferred Stock may convert
its shares of Cumulative Convertible Preferred Stock at any time into shares of
CMS Energy Common Stock under any of the following circumstances:

      -     during any calendar quarter (and only during such calendar quarter)
            if the last reported sale price of CMS Energy Common Stock for at
            least 20 trading days during the period of 30 consecutive trading
            days ending on the last trading day of the previous calendar quarter
            is greater than or equal to 120% of the conversion price per share
            of CMS Energy Common Stock on such last trading day;

      -     upon the occurrence of specified corporate transactions; and

      -     subject to certain exceptions, during the five business day period
            immediately following any ten consecutive trading-day period in
            which the trading price per share of Cumulative Convertible
            Preferred Stock for each day of that period was less than 95% of the
            product of the closing sale price of CMS Energy Common Stock and the
            applicable conversion rate of such share of Cumulative Convertible
            Preferred Stock; provided, however, a holder may not convert its
            shares of Cumulative Convertible Preferred Stock if the average
            closing sale price of CMS Energy Common Stock for such ten
            consecutive trading-day period was between the then current
            conversion price on the Cumulative Convertible Preferred Stock and
            120% of the then applicable conversion price on the Cumulative
            Convertible Preferred Stock.

      For each share of Cumulative Convertible Preferred Stock surrendered for
conversion, holders will receive 5.0541 shares of CMS Energy Common Stock. This
represents an initial conversion price of $9.893 per share of CMS Energy Common
Stock. The conversion rate may be adjusted for certain reasons, but it will not
be adjusted for accumulated and unpaid dividends on the Preferred Stock.

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 Debt Securities, depends and will depend
substantially upon timely receipt of sufficient dividends or other distributions
from its subsidiaries, in particular Consumers and Enterprises. Each of
Consumers' and Enterprises' ability to pay dividends on its common stock

                                       12

depends upon its revenues, earnings and other factors. Consumers' revenues and
earnings will depend substantially upon rates authorized by the Michigan Public
Service Commission (the "MPSC").

      CMS Energy has pledged the common stock of its principal subsidiaries,
including Consumers, as security for bank credit facilities.

      Consumers' Restated Articles of Incorporation ("Articles") 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, 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%.

      In addition, Consumers' indenture dated as of January 1, 1996, between
Consumers and The Bank of New York, as trustee (the "Preferred Securities
Indenture"), and a certain preferred securities guarantee by Consumers dated May
31, 2001 (the "Consumers Preferred Securities Guarantee"), in connection with
which the 9.00% Trust Preferred Securities of Consumers Energy Company Financing
IV (the "Consumers Trust Preferred Securities") 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 Preferred Securities Indenture or the
trust agreements pursuant to which the Consumers Trust Preferred Securities were
issued, (ii) a default has occurred with respect to its payment of any
obligations under the Consumers Preferred Securities Guarantees or certain
Consumers common stock guarantees or (iii) it gives notice of its election to
extend the interest payment period on the subordinated notes issued under the
Preferred Securities 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.

      Consumers' ability to pay dividends is also restricted by the Third
Amended and Restated Credit Agreement dated as of May 18, 2005 among Consumers,
JPMorgan Chase Bank, N.A., as administrative agent, and the financial
institutions named therein. Pursuant to this loan agreement, so long as there
exists no event of default under the agreement, Consumers may pay dividends in
an aggregate amount not to exceed $300 million during any calendar year.

      Consumers' Articles also prohibit the payment of cash dividends on its
common stock if Consumers is in arrears on preferred stock dividend payments.

      In addition, Michigan law prohibits payment of a dividend if, after giving
it effect, Consumers or Enterprises would not be able to pay its respective
debts as they become due in the usual course of business, or its respective
total assets would be less than the sum of its respective total liabilities
plus, unless the respective Articles of Incorporation permit otherwise, the
amount that would be needed, if Consumers or Enterprises 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. Currently, it is Consumers' policy to pay annual
dividends equal to 80% of its annual consolidated net income. Consumers' Board
of Directors reserves the right to change this policy at any time.

DEBT SECURITIES

      The Debt Securities offered by this prospectus will be unsecured
obligations of CMS Energy and will be either senior or subordinated debt. Senior
Debentures will be issued under a senior debt indenture and Subordinated
Debentures will be issued under a subordinated debt indenture. The senior debt
indenture and the subordinated debt indenture are sometimes referred to in this
prospectus individually as an "indenture" and collectively as the "indentures."

      The following briefly summarizes the material provisions of the indentures
and the Debt Securities. You should read the more detailed provisions of the
applicable indenture, including the defined terms, for provisions that may be
important to you.

                                       13


You should also read the particular terms of a series of Debt Securities, which
will be described in more detail in the applicable prospectus supplement. Copies
of the indentures may be obtained from CMS Energy or the applicable trustee.

      Unless otherwise provided in the applicable prospectus supplement, the
trustee under the senior debt indenture will be J.P. Morgan Trust Company, N.A.
and the trustee under the subordinated debt indenture will be The Bank of New
York.

GENERAL

      The indentures provide that Debt Securities of CMS Energy may be issued in
one or more series, with different terms, in each case as authorized from time
to time by CMS Energy.

      Federal income tax consequences and other special considerations
applicable to any Debt Securities issued by CMS Energy at a discount will be
described in the applicable prospectus supplement.

      Because CMS Energy is a holding company, the claims of creditors of CMS
Energy's subsidiaries will have a priority over CMS Energy's equity rights and
the rights of CMS Energy's creditors, including the holders of Debt Securities,
to participate in the assets of the subsidiary upon the subsidiary's
liquidation.

      The applicable prospectus supplement relating to any series of Debt
Securities will describe the following terms, where applicable:

      -     the title of the Debt Securities;

      -     whether the Debt Securities will be senior or subordinated debt;

      -     the total principal amount of the Debt Securities;

      -     the percentage of the principal amount at which the Debt Securities
            will be sold and, if applicable, the method of determining the
            price;

      -     the maturity date or dates;

      -     the interest rate or the method of computing the interest rate;

      -     the date or dates from which any interest will accrue, or how such
            date or dates will be determined, and the interest payment date or
            dates and any related record dates;

      -     the location where payments on the Debt Securities will be made;

      -     the terms and conditions on which the Debt Securities may be
            redeemed at the option of CMS Energy;

      -     any obligation of CMS Energy to redeem, purchase or repay the Debt
            Securities at the option of a holder upon the happening of any event
            and the terms and conditions of redemption, purchase or repayment;

      -     any provisions for the discharge of CMS Energy's obligations
            relating to the Debt Securities by deposit of funds or United States
            government obligations;

      -     whether the Debt Securities are to trade in book-entry form and the
            terms and any conditions for exchanging the global security in whole
            or in part for paper certificates;

      -     any material provisions of the applicable indenture described in
            this prospectus that do not apply to the Debt Securities;

      -     any additional amounts with respect to the Debt Securities that CMS
            Energy will pay to a non-United States person because of any tax,
            assessment or governmental charge withheld or deducted and, if so,
            any option of CMS Energy to redeem the Debt Securities rather than
            paying these additional amounts; and

      -     any other specific terms of the Debt Securities.

                                       14



CONCERNING THE TRUSTEES

      Each of J.P. Morgan Trust Company, N.A., the trustee under the senior debt
indenture, and 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

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

PAYMENT

      Distributions on the Debt Securities in registered form will be made at
the office or agency of the applicable trustee in the Borough of Manhattan, The
City of New York or its other designated office. However, at the option of CMS
Energy, payment of any interest may be made by check or by wire transfer.
Payment of any interest due on Debt Securities in registered form will be made
to the persons in whose name the Debt Securities are registered at the close of
business on the record date for such interest payments. Payments made in any
other manner will be specified in the prospectus supplement.

EVENTS OF DEFAULT

      Each indenture provides that events of default regarding any series of
Debt Securities will be:

      -     failure to pay required interest on any Debt Security of such series
            for 30 days;

      -     failure to pay principal other than a scheduled installment payment
            or premium, if any, on any Debt Security of such series when due;

      -     failure to make any required scheduled installment payment for 30
            days on Debt Securities of such series;

      -     failure to perform for 90 days after notice any other covenant in
            the relevant indenture other than a covenant included in the
            relevant indenture solely for the benefit of a series of Debt
            Securities other than such series;

      -     certain events of bankruptcy or insolvency, whether voluntary or
            not; or

      -     entry of final judgments against CMS Energy or Consumers for more
            than $25,000,000 which remain undischarged or unbonded for 60 days
            or a default resulting in the acceleration of indebtedness of CMS
            Energy or Consumers of more than $25,000,000, and the acceleration
            has not been rescinded or annulled within 10 days after written
            notice of such default as provided in the applicable indenture.

      Additional events of default may be prescribed for the benefit of the
holders of a particular series of Debt Securities and will be described in the
prospectus supplement relating to those Debt Securities.

      If an event of default regarding Debt Securities of any series issued
under the indentures should occur and be continuing, either the trustee or the
holders of 25% in the principal amount of outstanding Debt Securities of such
series may declare each Debt Security of that series due and payable.

      Holders of a majority in principal amount of the outstanding Debt
Securities of any series will be entitled to control certain actions of the
trustee under the indentures and to waive past defaults regarding such series.
The trustee generally will not be

                                       15


requested, ordered or directed by any of the holders of Debt Securities, unless
one or more of such holders shall have offered to the trustee reasonable
security or indemnity.

      Before any holder of any series of Debt Securities may institute action
for any remedy, except payment on such holder's Debt Security when due, the
holders of not less than 25% in principal amount of the Debt Securities of that
series outstanding must request the trustee to take action. Holders must also
offer and give the satisfactory security and indemnity against liabilities
incurred by the trustee for taking such action.

      CMS Energy is required to annually furnish the relevant trustee a
statement as to CMS Energy's compliance with all conditions and covenants under
the applicable indenture. Each indenture provides that the relevant trustee may
withhold notice to the holders of the Debt Securities of any series of any
default affecting such series, except payment on holders' Debt Securities when
due, if it considers withholding notice to be in the interests of the holders of
the Debt Securities of such series.

CONSOLIDATION, MERGER OR SALE OF ASSETS

      Each 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 the new corporation assumes the
obligations of CMS Energy under the Debt Securities and the indentures and is
organized and existing under the laws of the United States of America, any U.S.
state or the District of Columbia.

MODIFICATION OF THE INDENTURE

      Each indenture permits CMS Energy and the relevant trustee to enter into
supplemental indentures without the consent of the holders of the Debt
Securities to establish the form and terms of any series of securities under
that indenture.

      Each indenture also permits CMS Energy and the relevant trustee, with the
consent of the holders of a majority in total principal amount of the Debt
Securities of all series then outstanding and affected (voting as one class), to
change in any manner the provisions of the applicable indenture or modify in any
manner the rights of the holders of the Debt Securities of each such affected
series. CMS Energy and the relevant trustee may not, without the consent of the
holder of each Debt Security affected, enter into any supplemental indenture to:

      -     change the time of payment of the principal;

      -     reduce the principal amount of such Debt Security;

      -     reduce the rate or change the time of payment of interest on such
            Debt Security;

      -     reduce the amount payable on any securities issued originally at a
            discount upon acceleration or provable in bankruptcy; or

      -     impair the right to institute suit for the enforcement of any
            payment on any Debt Security when due.

      In addition, no such modification may reduce the percentage in principal
amount of the Debt Securities of the affected series, the consent of whose
holders is required for any such modification or for any waiver provided for in
the applicable indenture.

      Prior to the acceleration of the maturity of any Debt Security, the
holders, voting as one class, of a majority in total principal amount of the
Debt Securities with respect to which a default or event of default shall have
occurred and be continuing may on behalf of the holders of all such affected
Debt Securities waive any past default or event of default and its consequences,
except a default or an event of default in respect of a covenant or provision of
the applicable indenture or of any Debt Security which cannot be modified or
amended without the consent of the holder of each Debt Security affected.


                                       16

DEFEASANCE, COVENANT DEFEASANCE AND DISCHARGE

      Each indenture provides that, at the option of CMS Energy:

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

      -     CMS Energy need not comply with certain restrictive covenants of the
            relevant indenture (including those described under "Consolidation,
            Merger or Sale of Assets"),

if CMS Energy in each case irrevocably deposits in trust with the relevant
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 and interest on the Debt Securities of such
series on the stated maturities of such Debt Securities in accordance with the
terms thereof.

      To exercise this option, CMS Energy is required to deliver to the relevant
trustee an opinion of independent counsel to the effect that:

      -     the exercise of such option would not cause the holders of the Debt
            Securities of such series to recognize income, gain or loss for
            United States federal income tax purposes as a result of such
            defeasance, and such holders will be subject to United States
            federal income tax on the same amounts, in the same manner and at
            the same times as would have been the case if such defeasance had
            not occurred; and

      -     in the case of a discharge as described above, 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 applicable indenture there has been a change in the
            applicable federal income tax law.

      In the event:

      -     CMS Energy exercises its option to effect a covenant defeasance with
            respect to the Debt Securities of any series as described above,

      -     the Debt Securities of such series are thereafter declared due and
            payable because of the occurrence of any event of default other than
            an event of default caused by failing to comply with the covenants
            which are defeased, or

      -     the amount of money and securities on deposit with the relevant
            trustee would be insufficient to pay amounts due on the Debt
            Securities of such series at the time of the acceleration resulting
            from such event of default,

CMS Energy would remain liable for such amounts.

GOVERNING LAW

      Each indenture and the Debt Securities will be governed by, and construed
in accordance with, the laws of the State of Michigan unless the laws of another
jurisdiction shall mandatorily apply.

SENIOR DEBENTURES

      The Senior Debentures will be issued under the senior debt indenture and
will rank on an equal basis with all other unsecured debt of CMS Energy except
subordinated debt.

SUBORDINATED DEBENTURES

      The Subordinated Debentures will be issued under the subordinated debt
indenture and will rank subordinated and junior in right of payment, to the
extent set forth in the subordinated debt indenture, to all Senior Indebtedness
(as defined below) of CMS Energy.

                                       17


      If CMS Energy defaults in the payment of any distributions on any Senior
Indebtedness when it becomes due and payable after any applicable grace period,
then, unless and until the default is cured or waived or ceases to exist, CMS
Energy cannot make a payment on account of or redeem or otherwise acquire the
Subordinated Debentures. 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. If there is any insolvency, bankruptcy, liquidation or other similar
proceeding relating to CMS Energy, its creditors or its property, then all
Senior Indebtedness must be paid in full before any payment may be made to any
holders of Subordinated Debentures. Holders of Subordinated Debentures must
return and deliver any payments received by them, other than in a plan of
reorganization or through a defeasance trust as described above, directly to the
holders of Senior Indebtedness until all Senior Indebtedness is paid in full.

      "Senior Indebtedness" means distributions on the following, whether
outstanding on the date of execution of the subordinated debt indenture or
thereafter incurred, created or assumed:

      -     indebtedness of CMS Energy for money borrowed by CMS Energy or
            evidenced by debentures (other than the Subordinated Debentures),
            notes, bankers' acceptances or other corporate debt securities or
            similar instruments issued by CMS Energy;

      -     obligations of CMS Energy with respect to letters of credit;

      -     all indebtedness of others of the type referred to in the two
            preceding clauses assumed by or guaranteed in any manner by CMS
            Energy or in effect guaranteed by CMS Energy; or

      -     renewals, extensions or refundings of any of the indebtedness
            referred to in the preceding three clauses unless, in the case of
            any particular indebtedness, renewal, extension or refunding, under
            the express provisions of the instrument creating or evidencing the
            same or the assumption or guarantee of the same, or pursuant to
            which the same is outstanding, such indebtedness or such renewal,
            extension or refunding thereof is not superior in right of payment
            to the subordinated debt securities.

      The subordinated debt indenture does not limit the total amount of Senior
Indebtedness that may be issued.

CERTAIN COVENANTS

      If Debt Securities are issued to a Trust or a trustee of such Trust in
connection with the issuance of Trust 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 (in the case of Subordinated Debentures) with or junior (in the
case of Senior and Subordinated Debentures) to that Debt Security (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, liquidation, interest, principal or guarantee payment
is being made, (b) payments under the Guarantees, (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 under the indentures 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 Guarantees or (iii) CMS Energy shall have given notice of
its selection of an extension period as provided in the indentures with respect
to the Debt Securities 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 Trust Preferred Securities are outstanding, not
to convert the Debt Securities except pursuant to a notice of conversion
delivered to the Conversion Agent (as defined in the indentures) by a holder of
Trust Preferred Securities, (ii) to maintain directly or indirectly 100%
ownership of the Common Securities, provided that certain successors which are
permitted pursuant to the indentures may succeed to CMS Energy's ownership of

                                       18


the Common Securities, (iii) not to voluntarily terminate, wind-up or liquidate
such Trust, except (a) in connection with a distribution of the Debt Securities
to the holders of the Trust 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 Debt Securities then outstanding,
(v) to use its reasonable efforts, consistent with the terms and provisions of
the Trust Agreement, to cause such 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 Trust Preferred Securities to convert such
Trust Preferred Securities into CMS Energy Common Stock.

      As part of the Guarantees, CMS Energy will agree that it will honor all
obligations described therein relating to the conversion or exchange of the
Trust Preferred Securities into or for CMS Energy Common Stock, Senior
Debentures or Subordinated Debentures.

CONVERSION RIGHTS

      If the prospectus supplement provides, the holders of Debt Securities may
convert such Debt Securities 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 Debt Securities (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 Debt Security, unless CMS Energy
shall default in payment of the amount due upon redemption thereof.

      The conversion privilege and conversion price or conversion rate will be
adjusted in certain events, including if CMS Energy:

      -     pays a dividend or makes a distribution in shares of CMS Energy
            Common Stock;

      -     subdivides its outstanding shares of CMS Energy Common Stock into a
            greater number of shares;

      -     combines its outstanding shares of CMS Energy Common Stock into a
            smaller number of shares;

      -     pays a dividend or makes a distribution on its CMS Energy Common
            Stock other than in shares of its CMS Energy Common Stock;

      -     issues by reclassification of its shares of CMS Energy Common Stock
            any shares of its capital stock;

      -     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 as defined in the indentures) at a price per
            share less than the Average Market Price (as defined in the
            indentures) per share for such CMS Energy Common Stock; or

      -     distributes to all holders of shares of its CMS Energy Common Stock
            any assets or Debt Securities or any rights or warrants to purchase
            securities, provided that no adjustment shall be made under the last
            two bullet points 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.

      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 Debt Securities 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. 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
that is not made shall be carried forward and taken into account in any
subsequent adjustment. The foregoing conversion provisions may be modified to
the extent set forth in the prospectus supplement.

                                       19


TRUST PREFERRED SECURITIES

GENERAL

      Each Trust may issue, from time to time, Trust Preferred Securities having
terms described in the applicable prospectus supplement. The Trust Agreement of
each Trust will authorize the establishment of no more than one series of Trust
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 relevant Trust's trustees. Reference is made to the
prospectus supplement relating to the Trust Preferred Securities for specific
terms, including:

      -     the distinctive designation and the number of Trust Preferred
            Securities to be offered which will represent undivided beneficial
            interests in the assets of the Trust;

      -     the annual distribution rate and the dates or date upon which such
            distributions will be paid, provided, however, distributions on the
            Trust Preferred Securities will be paid quarterly in arrears to
            holders of Trust Preferred Securities as of a record date on which
            the Trust Preferred Securities are outstanding;

      -     whether holders can convert the Trust Preferred Securities into
            shares of CMS Energy Common Stock;

      -     whether distributions on Trust Preferred Securities would be
            deferred during any deferral of interest payments on the Debt
            Securities, provided, however, that no such deferral, including
            extensions, if any, may exceed 20 consecutive quarters nor extend
            beyond the stated maturity date of the Debt Securities, 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);

      -     the amount of any liquidation preference;

      -     the obligation, if any, of the Trust to redeem Trust Preferred
            Securities through the exercise by CMS Energy of an option on the
            corresponding Debt Securities and the price or prices at which, the
            period or periods within which and the terms and conditions upon
            which Trust Preferred Securities shall be purchased or redeemed, in
            whole or in part, pursuant to such obligation;

      -     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 Trust Preferred Securities shall
            be convertible or exchangeable at the option of the holder of the
            Trust Preferred Securities or other property or cash;

      -     the voting rights, if any, of the Trust Preferred Securities in
            addition to those required by law and in the Trust Agreement, or set
            forth under a Guarantee (as defined below);

      -     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 Trust 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
            Trust Preferred Securities would have reserved, had no such taxes,
            duties, assessments or governmental charges been imposed;

      -     the terms and conditions, if any, upon which the Debt Securities may
            be distributed to holders of Trust Preferred Securities; and

      -     any other relative rights, powers, preferences, privileges,
            limitations or restrictions of the Trust Preferred Securities not
            inconsistent with the Trust Agreement or applicable law. All Trust
            Preferred Securities offered hereby will be irrevocably guaranteed
            by CMS Energy, on a senior or subordinated basis, as applicable, and
            to the extent set forth below under "Effect of Obligations Under the
            Debt Securities and the Guarantees -- The Guarantees." Any
            applicable federal income tax considerations applicable to any
            offering of the Trust Preferred Securities will be described in the
            prospectus supplement relating thereto. The aggregate number of
            Trust Preferred Securities which the Trust shall have authority to
            issue will be pursuant to the terms of the Trust Agreement.

                                       20


                 EFFECT OF OBLIGATIONS UNDER THE DEBT SECURITIES
                               AND THE GUARANTEES

      As set forth in the Trust Agreement, the sole purpose of each Trust is to
issue the Trust Securities evidencing undivided beneficial interests in the
assets of each Trust, and to invest the proceeds from such issuance and sale to
acquire directly the Debt Securities from CMS Energy.

      As long as payments of interest and other payments are made when due on
the Debt Securities, such payments will be sufficient to cover distributions and
payments due on the Trust Securities because of the following factors:

      -     the aggregate principal amount of Debt Securities will be equal to
            the sums of the aggregate stated liquidation amount of the Trust
            Securities;

      -     the interest rate and the interest and other payment dates on the
            Debt Securities will match the distribution rate and distribution
            and other payment dates for the Trust Securities;

      -     CMS Energy shall pay, 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

      -     the Trust Agreement further provides that the 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 therefor are available) and
other payments due on the Trust 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 Debt Securities purchased by the Trust, it is expected that the
Trust will not have sufficient funds to pay distributions on the Trust Preferred
Securities. The Guarantees do 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 Trust Preferred Securities only if and to the extent that
CMS Energy has made a payment of interest or principal on the Debt Securities
held by the Trust as its sole asset. The Guarantees, when taken together with
CMS Energy's obligations under the Debt Securities 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's securities), provide a full and unconditional guarantee of amounts on
the Trust Preferred Securities.

      If CMS Energy fails to make interest or other payments on the Debt
Securities when due (taking account of any extension period), the Trust
Agreement provides a mechanism whereby the holders of the Trust Preferred
Securities may direct a Property Trustee to enforce its rights under the Debt
Securities. If a Property Trustee fails to enforce its rights under the Debt
Securities, a holder of Trust Preferred Securities may institute a legal
proceeding against CMS Energy to enforce a Property Trustee's rights under the
Debt Securities without first instituting any legal proceeding against a
Property 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 Debt Securities on the date such interest or principal is
otherwise payable (or in the case of redemption on the redemption date), then a
holder of Trust Preferred Securities may institute legal proceedings directly
against CMS Energy to obtain payment. If CMS Energy fails to make payments under
the Guarantees, the Guarantees provide a mechanism whereby the holders of the
Trust Preferred Securities may direct a Guarantee Trustee to enforce its rights
thereunder. Any holder of Trust Preferred Securities may institute a legal
proceeding directly against CMS Energy to enforce a Guarantee Trustee's rights
under a Guarantee without first instituting a legal proceeding against the
Trust, the Guarantee Trustee, or any other person or entity.

THE GUARANTEES

      Set forth below is a summary of information concerning the Guarantees that
will be executed and delivered by CMS Energy for the benefit of the holders,
from time to time, of the Trust Preferred Securities. Each Guarantee will be
qualified as an indenture under the Trust Indenture Act of 1939. Either The Bank
of New York, or J.P. Morgan Trust Company, N.A., each an independent trustee,
will act as indenture trustee under the Guarantees for the purpose of compliance
with the provisions of the Trust Indenture Act of 1939. This summary does not
purport to be complete and is subject in all respects to the provisions

                                       21


of, and is qualified in its entirety by reference to, the Guarantees, which are
filed as exhibits to the Registration Statement of which this prospectus forms a
part.

GENERAL

      CMS Energy will irrevocably agree to pay in full, on a senior or
subordinated basis, as applicable, to the extent set forth herein, the Guarantee
Payments (as defined below) to the holders of the Trust 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 Trust Preferred Securities, to the extent not paid
by or on behalf of the Trust (the "Guarantee Payments"), will be subject to a
Guarantee: (i) any accumulated and unpaid distributions required to be paid on
the Trust 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
Trust 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 Debt
Securities are distributed to holders of the Trust 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 Trust 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
Trust Preferred Securities or by causing the Trust to pay such amount to such
holders.

      Such Guarantees will be irrevocable guarantees, on a senior or
subordinated basis, as applicable, of the Trust's obligations under the Trust
Preferred Securities, but will apply only to the extent that the Trust has funds
sufficient to make such payments, and are not guarantees of collection. If CMS
Energy does not make interest payments on the Debt Securities held by the Trust,
the Trust will not be able to pay distributions on the Trust Preferred
Securities and will not have funds legally available therefor.

      CMS Energy has, through the Guarantees, the Trust Agreements, the Senior
Debentures, the Subordinated Debentures, the indentures and the related Expense
Agreement, taken together, fully, irrevocably and unconditionally guaranteed all
of the Trust's obligations under the Trust 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 Trust 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 Guarantees, except that upon the occurrence and during
the continuation of a Trust Agreement event of default, holders of Trust
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 each Guarantee that if and so long as (i) the
Trust is the holder of all the Debt Securities, (ii) a Tax Event (as defined in
the Guarantee) 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 (as defined in the Guarantee) in respect of the Trust 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 (in the case of Subordinated Debentures with or junior in the
case of the Senior and Subordinated Debentures) to the Debt Securities (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, liquidation, interest, principal or guarantee payment
is being made, (b) payments under the Guarantees, (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

                                       22


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 Guarantee or (iii) CMS Energy shall have given notice of
its selection of an extension period as provided in the indentures with respect
to the Debt Securities and shall not have rescinded such notice, or such
extension period, or any extension thereof, shall be continuing. CMS Energy also
will covenant to (i) for so long as Trust Preferred Securities are outstanding,
not convert Debt Securities except pursuant to a notice of conversion delivered
to the Conversion Agent by a holder of Trust Preferred Securities, (ii) maintain
directly or indirectly 100% ownership of the Common Securities, provided that
certain successors which are permitted pursuant to the indentures may succeed to
CMS Energy's ownership of the Common Securities, (iii) not voluntarily
terminate, wind-up or liquidate the Trust, except (a) in connection with a
distribution of the Debt Securities to the holders of the Trust Preferred
Securities in liquidation of the Trust or (b) in connection with certain
mergers, consolidations or amalgamations permitted by the Trust Agreement, (iv)
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 Debt Securities then outstanding, (v) 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) deliver
shares of CMS Energy Common Stock upon an election by the holders of the Trust
Preferred Securities to convert such Trust Preferred Securities into CMS Energy
Common Stock.

      As part of the Guarantees, CMS Energy will agree that it will honor all
obligations described therein relating to the conversion or exchange of the
Trust Preferred Securities into or for CMS Energy Common Stock, Senior
Debentures or Subordinated Debentures.

AMENDMENTS AND ASSIGNMENT

      Except with respect to any changes that do not materially adversely affect
the rights of holders of the Trust Preferred Securities (in which case no vote
will be required), the Guarantees may not be amended without the prior approval
of the holders of a majority in aggregate liquidation amount of such outstanding
Trust Preferred Securities. All guarantees and agreements contained in the
Guarantees shall bind the successors, assigns, receivers, trustees and
representatives of CMS Energy and shall inure to the benefit of the holders of
the Trust Preferred Securities then outstanding.

TERMINATION OF THE GUARANTEES

      The Guarantees will terminate and be of no further force and effect upon
full payment of the redemption price of the Trust 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 Trust
Preferred Securities in respect of the conversion of all such holders' Trust
Preferred Securities into CMS Energy Common Stock or upon distribution of the
Debt Securities to the holders of the Trust Preferred Securities in exchange for
all of the Trust Preferred Securities. The Guarantees will continue to be
effective or will be reinstated, as the case may be, if at any time any holder
of Trust Preferred Securities must restore payment of any sums paid under such
Trust Preferred Securities or the Guarantees.

EVENTS OF DEFAULT

      An event of default under a 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 Trust Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to a Guarantee Trustee in respect of a
Guarantee or to direct the exercise of any trust or power conferred upon a
Guarantee Trustee under the Guarantees.

      If a Guarantee Trustee fails to enforce a Guarantee, any holder of the
Trust Preferred Securities may institute a legal proceeding directly against CMS
Energy to enforce its rights under such 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 Trust 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 a 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.

                                       23


      CMS Energy, as guarantor, is required to file annually with each 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 Guarantees.

STATUS OF THE GUARANTEES

      The Guarantees will constitute unsecured obligations of CMS Energy and
will rank equal to or subordinate and junior in right of payment to all other
liabilities of CMS Energy, as applicable. The Guarantees will rank pari passu
with or senior to, as applicable, 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 Guarantees will constitute a guarantee of payment and not of
collection which means that 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 Guarantees will be held for the benefit of the holders of the
Trust Preferred Securities. The Guarantees 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 Debt Securities to the holders of the Trust Preferred
Securities. The Guarantees do 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 be issued separately or as part of Stock Purchase
Units consisting of a Stock Purchase Contract and Senior Debentures,
Subordinated Debentures, Trust Preferred Securities or debt obligations of third
parties, including U.S. Treasury securities, securing the holders' obligations
to purchase the Common Stock under 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 vice 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 the prospectus
supplement will not purport to be complete 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.

                              PLAN OF DISTRIBUTION

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

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

                                       24


prospectus supplement relating thereto, the obligations of the underwriters to
purchase the Offered Securities will be subject to certain conditions precedent,
and the underwriters will be obligated to purchase all the Offered Securities if
any are purchased.

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

      The Offered Securities may be sold directly by CMS Energy and/or the
Trusts to institutional investors or others, who may be deemed to be
underwriters within the meaning of the Securities Act of 1933, as amended (the
"Securities Act"), with respect to any resale thereof. The terms of any such
sales will be described in the prospectus supplement relating thereto.

      The CMS Energy Common Stock may be offered other than through the
facilities of a national securities exchange and other than to or through a
market maker other than on an exchange.

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

      The Offered Securities may also be offered and sold, if so indicated in
the applicable prospectus supplement, in connection with a remarketing upon
their purchase, in accordance with a redemption or repayment pursuant to their
terms, or otherwise, by one or more firms ("remarketing firms"), acting as
principals for their own accounts or as agents for CMS Energy and/or the Trusts.
Any remarketing firm will be identified and the terms of its agreement, if any,
with its compensation will be described in the applicable prospectus supplement.
Remarketing firms may be deemed to be underwriters, as such term is defined in
the Securities Act, in connection with the Offered Securities remarketed
thereby. Remarketing firms may be entitled under agreements which may be entered
into with CMS Energy and/or the Trusts to indemnification or contribution by CMS
Energy and/or the Trusts against certain civil liabilities, including
liabilities under the Securities Act, and may be customers of, engage in
transactions with, or perform services for, CMS Energy and its subsidiaries in
the ordinary course of business.

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

      We may engage J.P. Morgan Securities Inc. ("JPMS") or Brinson Patrick
Securities Corporation ("Brinson") (JPMS and Brinson collectively, the "Agents")
to act as agent or principal for offerings from time to time of shares of CMS
Energy Common Stock in one or more placements pursuant to the terms of a
distribution agreement between us and either JPMS or Brinson. The terms of sales
to or through the Agents pursuant to a distribution agreement will be set out in
more detail in a prospectus supplement to this prospectus. When acting as agent,
the Agents will use commercially reasonable efforts to sell the shares pursuant
to the terms agreed to with us, including the number of shares to be offered in
the placement and any minimum price below which sales may not be made. The
Agents, in their capacity as agent or principal, could arrange for or make sales
in privately negotiated transactions, at the market in the existing trading
market for CMS Energy Common Stock, including sales made to or through a market
maker or through an electronic communications network, or in any other manner
that may be deemed to be an "at-the-market offering" as defined in Rule 415
promulgated under the Securities Act and/or any other method permitted by law.

      CMS Energy Common Stock sold through the Agents in any at-the-market
offerings will be sold at prices related to the prevailing market price for such
securities, and therefore exact figures regarding proceeds that will be raised
or commissions to be paid are impossible to determine. We will report at least
quarterly the number of shares of CMS Energy Common Stock sold to or through the
Agents in at-the-market offerings, the net proceeds to us and the compensation
paid by us to the Agents in connection with such sales of CMS Energy Common
Stock. Pursuant to the terms of a distribution agreement with the Agents or any
other distribution agreement we may enter into, we also may agree to sell, and
the relevant underwriters or agents may agree to solicit offers to purchase,
blocks of CMS Energy Common Stock or other securities. The total number of
shares that we may sell in at-the-market offerings will be disclosed in a
prospectus supplement to this prospectus.

      In connection with the offering of the securities, certain underwriters
and selling group members and their respective affiliates may engage in
transactions that stabilize, maintain or otherwise affect the market price of
the applicable securities.

                                       25


These transactions may include stabilization transactions effected in accordance
with Rule 104 of Regulation M promulgated by the SEC pursuant to which these
persons may bid for or purchase securities for the purpose of stabilizing their
market price.

      If indicated in the applicable prospectus supplement, we will authorize
underwriters, dealers or agents to solicit offers by institutional investors to
purchase securities from us pursuant to contracts providing for payment and
delivery at a future date. In all cases, these purchasers must be approved by
us. Unless otherwise set forth in the applicable prospectus supplement, the
obligations of any purchaser under any of these contracts will not be subject to
any conditions, except that the purchase of the securities must not at the time
of delivery be prohibited under the laws of any jurisdiction to which that
purchaser is subject and if securities also are being sold to underwriters, we
must have sold to these underwriters the securities not subject to delayed
delivery. Underwriters and other agents will not have any responsibility in
respect of the validity or performance of these contracts.

      Under the securities laws of some states, the securities registered by the
registration statement that includes this prospectus may be sold in those states
only through registered or licensed brokers or dealers. Any person participating
in the distribution of the securities registered under the registration
statement that includes this prospectus will be subject to applicable provisions
of the Exchange Act, and the applicable rules and regulations of the SEC,
including, among others, Regulation M noted above, which may limit the timing of
purchases and sales of any of the securities by any such person. Furthermore,
Regulation M may restrict the ability of any person engaged in the distribution
of the securities to engage in market-making activities with respect to the
securities. These restrictions may affect the marketability of the securities
and the ability of any person or entity to engage in market-making activities
with respect to the securities.

      We may enter into derivative transactions with third parties, or sell
securities not covered by this prospectus to third parties in privately
negotiated transactions. If the applicable prospectus supplement indicates, in
connection with those derivatives, the third parties may sell securities covered
by this prospectus and the applicable prospectus supplement, including in short
sale transactions. If so, the third parties may use securities pledged by us or
borrowed from us or others to settle those sales or to close out any related
open borrowings of stock, and may use securities received from us in settlement
of those derivatives to close out any related open borrowings of stock. The
third parties in such sale transactions will be underwriters and, if not
identified in this prospectus, will be identified in the applicable prospectus
supplement (or a post-effective amendment).

      We or one of our affiliates may loan or pledge securities to a financial
institution or other third party that in turn may sell the securities using this
prospectus. Such financial institution or third party may transfer its short
position to investors in our securities or in connection with a simultaneous
offering of other securities offered by this prospectus or otherwise.

                                 LEGAL OPINIONS

      Opinions as to the legality of certain of the Offered Securities will be
rendered for CMS Energy by Robert C. Shrosbree, Esq., Assistant General Counsel
for CMS Energy. Certain matters of Delaware law relating to the validity of the
Trust Preferred Securities will be passed upon on behalf of the Trusts by
Skadden, Arps, Slate, Meagher & Flom LLP, special Delaware counsel to the
Trusts. Certain United States Federal income taxation matters may be passed upon
for CMS Energy and the Trust by either Theodore Vogel, tax counsel for CMS
Energy, or by special tax counsel to CMS Energy and of the Trust, who will be
named in the prospectus supplement. Certain legal matters with respect to
Offered Securities will be passed upon by counsel for any underwriters, dealers
or agents, each of whom will be named in the related prospectus supplement.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

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

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

            CMS Energy's Bylaws provide:

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

            Article VIII of CMS Energy's Articles of Incorporation, as amended
            reads:

      A director shall not be personally liable to the Corporation or its
shareholders for monetary damages for breach of duty as a director except (i)
for a breach of the director's duty of loyalty to the Corporation or its
shareholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) for a violation of
Section 551(1) of the Michigan Business Corporation Act, and (iv) for any
transaction from which the director derived an improper personal benefit. No
amendment to or repeal of this Article VIII, and no modification to its
provisions by law, shall apply to, or have any effect upon, the liability or
alleged liability of any director of the Corporation for or with respect to any
acts or omissions of such director occurring prior to such amendment, repeal or
modification.

            Article IX of CMS Energy's Articles of Incorporation, as amended
            reads:

                                     II-1


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

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

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

ITEM 17. UNDERTAKINGS.

      The undersigned registrants hereby undertake:

      (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement: (i) To include any
prospectus required by Section 10(a)(3) of the Securities Act; (ii) To reflect
in the prospectus any facts or events arising after the effective date of the
registration statement (or the most recent post-effective amendment thereof)
which, individually or in the aggregate, represent a fundamental change in the
information set forth in the registration statement. Notwithstanding the
foregoing, any increase or decrease in volume of securities offered (if the
total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of prospectus filed with the
Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume
and price represent no more than a 20% change in the maximum aggregate offering
price set forth in the "Calculation of Registration Fee" table in the effective
registration statement; (iii) To include any material information with respect
to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in the registration
statement; provided, however, that (i) and (ii) do not apply if the registration
statement is on Form S-3 or Form S-8, and the information required to be
included in a post-effective amendment by those paragraphs is contained in
periodic reports filed with or furnished to the Commission by the registrant
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in the registration statement.

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

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

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

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

      (6) That (1) for purposes of determining any liability under the
Securities Act of 1933, the information omitted from the form of prospectus
filed as part of this Registration Statement in reliance upon Rule 430A and
contained in a form of prospectus filed by the registrant pursuant to Rule
424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part
of this Registration Statement as of the time it was declared effective; and (2)
for the purpose of determining any liability under the Securities Act of 1933,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

                                     II-5


                                   SIGNATURES

Registration Statement to be signed on its behalf by the undersigned, thereunto
