           CMS Energy Corporation, a corporation duly organized and
existing under the laws of the State of Michigan (herein called the
"Issuer", which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
_________________________________, or registered assigns, the principal
sum of ____________________ Dollars on November 15, 2004 ("Maturity") and
to pay interest thereon from September 26, 1997 (the "Original Issue
Date") or from the most recent Interest Payment Date to which interest has
been paid or duly provided for, semi-annually on May 15 and November 15 in
each year, commencing November 15, 1997 and at Maturity at the rate of
_____% per annum, until the principal hereof is paid or made available for
payment.  The amount of interest payable on any Interest Payment Date
shall be computed on the basis of a 360-day year of twelve 30-day months. 
The interest so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this 2004 Note (or one or more Predecessor 2004

interest, which shall be the 1st day of the calendar month in which such
Interest Payment Date occurs (whether or not a Business Day) except that
the Record Date for interest payable at Maturity shall be the date of
Maturity.  Any such interest not so punctually paid or duly provided for
will forthwith cease to be payable to the Holder on such Record Date and
may either be paid to the Person in whose name this 2004 Note (or one or
more Predecessor 2004 Notes) is registered at the close of business on a
subsequent Record Date (which shall be not less than five Business Days
prior to the date of payment of such defaulted interest) for the payment
of such defaulted interest to be fixed by the Trustee, notice whereof
shall be given to Holders of 2004 Notes not less than 15 days preceding
such subsequent Record Date.

           Payment of the principal of (and premium, if any) and interest,
if any, on this 2004 Note will be made at the office or agency of the
Issuer maintained for that purpose in New York, New York (the "Place of
Payment"), in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private
debts; provided, however, that at the option of the Issuer payment of
interest (other than interest payable at Maturity) may be made by check
mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register or by wire transfer to an account
designated by such Person not later than ten days prior to the date of
such payment.

           Reference is hereby made to the further provisions of this 2004
Note set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

           Unless the certificate of authentication hereon has been
executed by the Trustee referred to on the reverse hereof by manual
signature, this 2004 Note shall not be entitled to any benefit under the
Indenture or be valid or obligatory for any purpose.

           IN WITNESS WHEREOF, the Issuer has caused this instrument to be
duly executed under its corporate seal.

           SECTION 2.04.  FORM OF REVERSE OF 2004 NOTE.

           This 7 5/8% Senior Unsecured Note Due 2004 is one of a duly
authorized issue of securities of the Issuer (herein called the "2004
Notes"), issued and to be issued under an Indenture, dated as of September
15, 1992, as supplemented by certain supplemental indentures, including
the Fourth Supplemental Indenture, dated as of September 26, 1997 (herein
collectively referred to as the "Indenture"), between the Issuer and NBD
Bank, a Michigan banking corporation (formerly known as NBD Bank, National
Association), as Trustee (herein called the "Trustee", which term includes
any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement
of the respective rights, limitations of rights, duties and immunities
thereunder of the Issuer, the Trustee, and the Holders of the 2004 Notes
and of the terms upon which the 2004 Notes are, and are to be,
authenticated and delivered.  This 2004 Note is one of the series
designated on the face hereof, limited in aggregate principal amount to
$180,000,000.

           The 2004 Notes are subject to redemption at the option of the
Issuer, in whole or in part, upon not more than 60 nor less than 30 days'
notice as provided in the Indenture at any time and from time to time, at
a redemption price equal to 100% of the principal amount of such 2004
Notes being redeemed plus the Applicable Premium, if any, thereon at the
time of redemption, together with accrued interest, if any, thereon to the
redemption date, but interest installments whose Stated Maturity is on or
prior to such redemption date will be payable to the Holder of record at
the close of business on the relevant Record Date referred to on the face
hereof, all as provided in the Indenture.  In no event will the redemption
price ever be less than 100% of the principal amount of the 2004 Notes
plus accrued interest to the redemption date.

     The following definitions are used to determine the Applicable
Premium:

           "Applicable Premium" means, with respect to a 2004 Note (or
portion thereof) being redeemed at any time, the excess of (A) the present
value at such time of the principal amount of such 2004 Note (or portion
thereof) being redeemed plus all interest payments due on such 2004 Note
(or portion thereof), which present value shall be computed using a
discount rate equal to the Treasury Rate plus 50 basis points, over
(B) the principal amount of such 2004 Note (or portion thereof) being
redeemed at such time.  For purposes of this definition, the present
values of the interest and principal payments will be determined in
accordance with generally accepted principles of financial analysis.

           "Treasury Rate" means the yield to maturity at the time of
computation of United States Treasury securities with a constant maturity
(as compiled and published in the most recent Federal Reserve Statistical
Release H.15(519) which has become publicly available at least two
business days prior to the redemption date or, in the case of defeasance,
prior to the date of deposit (or, if such Statistical Release is no longer
published, any publicly available source of similar market data)) most
nearly equal to the then remaining average life to stated maturity of the
2004 Notes; provided, however, that if the average life to stated maturity
of the 2004 Notes is not equal to the constant maturity of a United States
Treasury security for which a weekly average yield is given, the Treasury
Rate shall be obtained by linear interpolation (calculated to the nearest
one-twelfth of a year) from the weekly average yields of United States
Treasury securities for which such yields are given.

           In the event of redemption of this 2004 Note in part only, a
new 2004 Note for the unredeemed portion hereof will be issued in the name
of the Holder hereof upon the cancellation hereof.

           If a Change in Control occurs, the Issuer shall notify the
Holder of this 2004 Note of such occurrence and such Holder shall have the
right to require the Issuer to make a Required Repurchase of all or any
part of this 2004 Note at a Change in Control Purchase Price equal to 101%
of the principal amount of this 2004 Note to be so purchased as more fully
provided in the Indenture and subject to the terms and conditions set
forth therein.  In the event of a Required Repurchase of only a portion of
this 2004 Note, a new 2004 Note or Notes for the unrepurchased portion
hereof will be issued in the name of the Holder hereof upon the
cancellation hereof.

           If an Event of Default with respect to this 2004 Note shall
occur and be continuing, the principal of this 2004 Note may be declared
due and payable in the manner and with the effect provided in the
Indenture.

           In any case where any Interest Payment Date, repurchase date,
Stated Maturity or Maturity of any 2004 Note shall not be a Business Day
at any Place of Payment, then (notwithstanding any other provision of the
Indenture or this 2004 Note), payment of interest or principal (and
premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment
Date, repurchase date or at the Stated Maturity or Maturity; provided that
no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, redemption date, repurchase date, Stated
Maturity or Maturity, as the case may be, to such Business Day.

           The Indenture contains provisions for defeasance at any time of
(i) the entire indebtedness of this 2004 Note or (ii) certain restrictive
covenants and Events of Default with respect to this 2004 Note, in each
case upon compliance with certain conditions set forth therein.

           The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the rights of the Holders of all Outstanding
2004 Notes under the Indenture at any time by the Issuer and the Trustee
with the consent of the Holders of not less than a majority in principal
amount of Securities of all series then Outstanding and affected (voting
as one class).

           The Indenture permits the Holders of not less than a majority
in principal amount of Securities of all series at the time Outstanding
with respect to which a default shall have occurred and be continuing
(voting as one class) to waive on behalf of the Holders of all Outstanding
Securities of such series any past default by the Issuer, provided that no
such waiver may be made with respect to a default in the payment of the
principal of or the interest on any Security of such series or the default
by the Issuer in respect of certain covenants or provisions of the
Indenture, the modification or amendment of which must be consented to by
the Holder of each Outstanding Security of each series affected.

           As set forth in, and subject to, the provisions of the
Indenture, no Holder of any 2004 Note will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder,
unless such Holder shall have previously given to the Trustee written
notice of a continuing Event of Default, the Holders of not less than 25%
in principal amount of the Outstanding Securities of each affected series
(voting as one class) shall have made written request, and offered
reasonable indemnity, to the Trustee to institute such proceeding as
trustee, and the Trustee shall not have received from the Holders of a
majority in principal amount of the Outstanding Securities of each
affected series (voting as one class) a direction inconsistent with such
request and shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted
by the Holder hereof for the enforcement of payment of the principal of
(and premium, if any) or any interest on this 2004 Note on or after the
respective due dates expressed herein.

           No reference herein to the Indenture and no provision of this
2004 Note or of the Indenture shall alter or impair the obligation of the
Issuer, which is absolute and unconditional, to pay the principal of and
any premium and interest on this 2004 Note at the times, place and rate,
and in the coin or currency, herein prescribed.

           As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this 2004 Note is registerable in the
Security Register, upon surrender of this 2004 Note for registration of
transfer at the office or agency of the Issuer in any place where the
principal of and any premium and interest on this 2004 Note are payable,
duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Issuer and the Security Registrar duly executed
by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new 2004 Notes of this series and of like tenor, of
authorized denominations and for the same aggregate principal amount, will
be issued to the designated transferee or transferees.

           The 2004 Notes are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set
forth, 2004 Notes are exchangeable for a like aggregate principal amount
of 2004 Notes and of like tenor of a different authorized denomination, as
requested by the Holder surrendering the same.

           No service charge shall be made for any such registration of
transfer or exchange, but the Issuer may require payment of a sum
sufficient to cover any tax or other governmental charge payable in
connection therewith.

           The Issuer shall not be required to (a) issue, exchange or
register the transfer of this 2004 Note for a period of 15 days next
preceding the mailing of the notice of redemption of 2004 Notes or (b)
exchange or register the transfer of any 2004 Note or any portion thereof
selected, called or being called for redemption, except in the case of any
2004 Note to be redeemed in part, the portion thereof not so to be
redeemed.

           Prior to due presentment of this 2004 Note for registration of
transfer, the Issuer, the Trustee and any agent of the Issuer or the
Trustee may treat the Person in whose name this 2004 Note is registered as
the owner hereof for all purposes, whether or not this 2004 Note be
overdue, and neither the Issuer, the Trustee nor any such agent shall be
affected by notice to the contrary.

           All terms used in this 2004 Note without definition which are
defined in the Indenture shall have the meanings assigned to them in the
Indenture.

           SECTION 2.05.  FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION. 
The Trustee's certificates of authentication shall be in substantially the
following form:

           This is one of the Securities of the series designated herein
referred to in the within-mentioned Indenture.


                                         _____________________________,
                                                    as Trustee


                                         By ______________________________
                                                    Authorized Officer


                                ARTICLE III

                             CHANGE OF CONTROL

           SECTION 3.01.  CHANGE OF CONTROL.  Upon the occurrence of a
Change in Control (the effective date of such Change in Control being the
"Change in Control Date"), each Holder of a 2004 Note shall have the right
to require that the Issuer repurchase (a "Required Repurchase") all or any
part of such Holder's 2004 Note at a repurchase price payable in cash
equal to 101% of the principal amount of such 2004 Note plus accrued
interest to the Purchase Date (the "Change in Control Purchase Price").

           (a)  Within 30 days following the Change in Control Date, the
     Issuer shall mail a notice (the "Required Repurchase Notice") to each
     Holder with a copy to the Trustee stating:

                  (i)  that a Change in Control has occurred and that such
           Holder has the right to require the Issuer to repurchase all or
           any part of such Holder's 2004 Notes at the Change of Control
           Purchase Price;

                  (ii)  the Change of Control Purchase Price;

                  (iii)  the date on which any Required Repurchase shall
           be made (which shall be no earlier than 60 days nor later than
           90 days from the date such notice is mailed) (the "Purchase
           Date");

                  (iv)  the name and address of the Paying Agent; and

                  (v)  the procedures that Holders must follow to cause
           the 2004 Notes to be repurchased, which shall be consistent
           with this Section and the Indenture.

           (b)  Holders electing to have a 2004 Note repurchased must
     deliver a written notice (the "Change in Control Purchase Notice") to
     the Paying Agent (initially the Trustee) at its corporate trust
     office in Detroit, Michigan, or any other office of the Paying Agent
     maintained for such purposes, not later than 30 days prior to the
     Purchase Date.  The Change in Control Purchase Notice shall state:
     (i) the portion of the principal amount of any 2004 Notes to be
     repurchased, which portion must be $1,000 or an integral multiple
     thereof; (ii) that such 2004 Notes are to be repurchased by the
     Issuer pursuant to the change in control provisions of the Indenture;
     and (iii) unless the 2004 Notes are represented by one or more Global
     Notes, the certificate numbers of the 2004 Notes to be delivered by
     the Holder thereof for repurchase by the Issuer.  Any Change in
     Control Purchase Notice may be withdrawn by the Holder by a written
     notice of withdrawal delivered to the Paying Agent not later than
     three Business Days prior to the Purchase Date.  The notice of
     withdrawal shall state the principal amount and, if applicable, the
     certificate numbers of the 2004 Notes as to which the withdrawal
     notice relates and the principal amount of such 2004 Notes, if any,
     which remains subject to a Change in Control Purchase Notice.

           If a 2004 Note is represented by a Global Note (as described in
     Article VI below), the Depositary or its nominee will be the Holder
     of such 2004 Note and therefore will be the only entity that can
     elect a Required Repurchase of such 2004 Note.  To obtain repayment
     pursuant to this Section 3.01 with respect to such 2004 Note, the
     beneficial owner of such 2004 Note must provide to the broker or
     other entity through which it holds the beneficial interest in such
     2004 Note (i) the Change in Control Purchase Notice signed by such
     beneficial owner, and such signature must be guaranteed by a member
     firm of a registered national securities exchange or of the National
     Association of Securities Dealers, Inc. or a commercial bank or trust
     company having an office or correspondent in the United States, and
     (ii) instructions to such broker or other entity to notify the
     Depositary of such beneficial owner's desire to obtain repayment
     pursuant to this Section 3.01.  Such broker or other entity will
     provide to the Paying Agent (i) the Change of Control Purchase Notice
     received from such beneficial owner and (ii) a certificate
     satisfactory to the Paying Agent from such broker or other entity
     stating that it represents such beneficial owner.  Such broker or
     other entity will be responsible for disbursing any payments it
     receives pursuant to this Section 3.01 to such beneficial owner.

           (c)    Payment of the Change of Control Purchase Price for a
     2004 Note for which a Change in Control Purchase Notice has been
     delivered and not withdrawn is conditioned (except in the case of a
     2004 Note represented by one or more Global Notes) upon delivery of
     such 2004 Note (together with necessary endorsements) to the Paying
     Agent at its office in Detroit, Michigan, or any other office of the
     Paying Agent maintained for such purpose, at any time (whether prior
     to, on or after the Purchase Date) after the delivery of such Change
     in Control Purchase Notice.  Payment of the Change of Control
     Purchase Price for such 2004 Note will be made promptly following the
     later of the Purchase Date or the time of delivery of such 2004 Note. 
     If the Paying Agent holds, in accordance with the terms of the
     Indenture, money sufficient to pay the Change in Control Purchase
     Price of such 2004 Note on the Business Day following the Purchase
     Date, then, on and after such date, interest will cease accruing, and
     all other rights of the Holder shall terminate (other than the right
     to receive the Change of Control Purchase Price upon delivery of the
     2004 Note).

           (d)    The Issuer shall comply with the provisions of
     Regulation 14E and any other tender offer rules under the Exchange
     Act, which may then be applicable in connection with any offer by the
     Issuer to repurchase 2004 Notes at the option of Holders upon a
     Change in Control.

           (e)    No 2004 Note may be repurchased by the Issuer as a
     result of a Change in Control if there has occurred and is continuing
     an Event of Default (other than a default in the Payment of the
     Change in Control Purchase Price with respect to the 2004 Notes).


                                ARTICLE IV
                    ADDITIONAL COVENANTS OF THE ISSUER
                      WITH RESPECT TO THE 2004 Notes

           SECTION 4.01.  EXISTENCE.  So long as any of the 2004 Notes are
Outstanding, subject to Article 9 of the Original Indenture, the Issuer
will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence.

           SECTION 4.02.  LIMITATION ON CERTAIN LIENS.  (a)  So long as
any of the 2004 Notes are outstanding, the Issuer shall not create, incur,
assume or suffer to exist any lien, mortgage, pledge, security interest,
conditional sale, title retention agreement or other charge or encumbrance
of any kind, or any other type of arrangement intended or having the
effect of conferring upon a creditor of the Issuer or any Subsidiary a
preferential interest (hereinafter in this Section referred to as a
"Lien") upon or with respect to any of its property of any character,
including without limitation any shares of Capital Stock of Consumers or
Enterprises, without making effective provision whereby the 2004 Notes
shall (so long as any such other creditor shall be so secured) be equally
and ratably secured (along with any other creditor similarly entitled to
be secured) by a direct Lien on all property subject to such Lien,
provided, however, that the foregoing restrictions shall not apply to:

     (i)  Liens for taxes, assessments or governmental charges or levies
to the extent not past due;

     (ii)  pledges or deposits to secure (a) obligations under workmen's  
compensation laws or similar legislation, (b) statutory obligations
of the Issuer or (c) Support Obligations;

     (iii)  Liens imposed by law, such as materialmen's, mechanics',
carriers', workmen's and repairmen's Liens and other similar Liens arising
in the ordinary course of business securing obligations which are not
overdue or which have been fully bonded and are being contested in good
faith;

     (iv)  purchase money Liens upon or in property acquired and held by
the Issuer in the ordinary course of business to secure the purchase price
of such property or to secure Indebtedness incurred solely for the purpose
of financing the acquisition of any such property to be subject to such
Liens, or Liens existing on any such property at the time of acquisition,
or extensions, renewals or replacements of any of the foregoing for the
same or a lesser amount, provided that no such Lien shall extend to or
cover any property other than the property being acquired and no such
extension, renewal or replacement shall extend to or cover property not
theretofore subject to the Lien being extended, renewed or replaced, and
provided, further, that the aggregate principal amount of the Indebtedness
at any one time outstanding secured by Liens permitted by this clause (iv)
shall not exceed $10,000,000; and

     (v)  Liens not otherwise permitted by clauses (i) through (iv) of
this Section securing Indebtedness of the Issuer; provided that on the
date such Liens are created, and after giving effect to such Indebtedness,
the aggregate principal amount at maturity of all of the secured
Indebtedness of the Issuer at such date shall not exceed 5% of
Consolidated Net Tangible Assets at such date.

           SECTION 4.03.  LIMITATION ON CONSOLIDATION, MERGER, SALE OR
CONVEYANCE.  So long as any of the 2004 Notes are Outstanding and until
the 2004 Notes are rated BBB- or above (or an equivalent rating) by
Standard & Poor's and one Other Rating Agency (or, if Standard & Poor's
shall change its rating system, an equivalent of such rating then employed
by such organization), at which time the Issuer will be permanently
released from the provisions of this Section 4.03, and subject also to
Article Nine of the Indenture, the Issuer shall not consolidate with or
merge into any other Person or sell, lease or convey the property of the
Issuer in the entirety or substantially as an entirety, unless (i)
immediately after giving effect to such transaction the Consolidated Net
Worth of the surviving entity is at least equal to the Consolidated Net
Worth of the Issuer immediately prior to the transaction, and (ii) after
giving effect to such transaction, the surviving entity would be entitled
to incur at least one dollar of additional Indebtedness (other than
revolving Indebtedness to banks) without violation of the limitations in
Section 4.04 hereof.

           SECTION 4.04.  LIMITATION ON CONSOLIDATED INDEBTEDNESS. 
(a)  So long as any of the 2004 Notes are Outstanding and until the 2004
Notes are rated BBB- or above (or an equivalent rating) by Standard &
Poor's and one Other Rating Agency (or, if Standard & Poor's shall change
its rating system, an equivalent of such rating then employed by such
organization), at which time the Issuer will be permanently released from
the provisions of this Section 4.04, the Issuer shall not, and shall not
permit any Consolidated Subsidiary of the Issuer to, issue, create,
assume, guarantee, incur or otherwise become liable for (collectively,
"issue"), directly or indirectly, any Indebtedness unless the Consolidated
Coverage Ratio of the Issuer and its Consolidated Subsidiaries for the
four consecutive fiscal quarters immediately preceding the issuance of
such Indebtedness (as shown by a pro forma consolidated income statement
of the Issuer and its Consolidated Subsidiaries for the four most recent
fiscal quarters ending at least 30 days prior to the issuance of such
Indebtedness after giving effect to (i) the issuance of such Indebtedness
and (if applicable) the application of the net proceeds thereof to
refinance other Indebtedness as if such Indebtedness was issued at the
beginning of the period, (ii) the issuance and retirement of any other
Indebtedness since the first day of the period as if such Indebtedness was
issued or retired at the beginning of the period and (iii) the acquisition
of any company or business acquired by the Issuer or any Subsidiary since
the first day of the period (including giving effect to the pro forma
historical earnings of such company or business), including any
acquisition which will be consummated contemporaneously with the issuance
of such Indebtedness, as if in each case such acquisition occurred at the
beginning of the period) exceeds a ratio of 1.7 to 1.0.

           (b)  Notwithstanding the foregoing paragraph, the Issuer or any
Restricted Subsidiary may issue, directly or indirectly, the following
Indebtedness:

           (1)  Indebtedness of the Issuer to banks not to exceed
     $1,000,000,000 in aggregate outstanding principal amount at any time;

           (2)  Indebtedness (other than Indebtedness described in clause
     (1) of this Subsection) outstanding on the date of this Fourth
     Supplemental Indenture, as set forth on Schedule 4.04(b)(2) attached
     hereto and made a part hereof, and Indebtedness issued in exchange
     for, or the proceeds of which are used to refund or refinance, any
     Indebtedness permitted by this clause (2); provided, however, that
     (i) the principal amount (or accreted value in the case of
     Indebtedness issued at a discount) of the Indebtedness so issued
     shall not exceed the principal amount (or accreted value in the case
     of Indebtedness issued at a discount) of, premium, if any, and
     accrued but unpaid interest on, the Indebtedness so exchanged,
     refunded or refinanced and (ii) the Indebtedness so issued (A) shall
     not mature prior to the stated maturity of the Indebtedness so
     exchanged, refunded or refinanced, (B) shall have an Average Life
     equal to or greater than the remaining Average Life of the
     Indebtedness so exchanged, refunded or refinanced and (C) if the
     Indebtedness to be exchanged, refunded or refinanced is subordinated
     to the 2004 Notes, the Indebtedness is subordinated to the 2004 Notes
     in right of payment;

           (3)  Indebtedness of the Issuer owed to and held by a
     Subsidiary and Indebtedness of a Subsidiary owed to and held by the
     Issuer; provided, however, that, in the case of Indebtedness of the
     Issuer owed to and held by a Subsidiary, (i) any subsequent issuance
     or transfer of any Capital Stock that results in any such Subsidiary
     ceasing to be a Subsidiary or (ii) any transfer of such Indebtedness
     (except to the Issuer or a Subsidiary) shall be deemed for the
     purposes of this Subsection to constitute the issuance of such
     Indebtedness by the Issuer;

           (4)  Indebtedness of the Issuer issued in exchange for, or the
     proceeds of which are used to refund or refinance, Indebtedness of
     the Issuer issued in accordance with Subsection (a) of this Section,
     provided that (i) the principal amount (or accreted value in the case
     of Indebtedness issued at a discount) of the Indebtedness so issued
     shall not exceed the principal amount (or accreted value in the case
     of Indebtedness issued at a discount) of, premium, if any, and
     accrued but unpaid interest on, the Indebtedness so exchanged,
     refunded or refinanced and (ii) the Indebtedness so issued (A) shall
     not mature prior to the stated maturity of the Indebtedness so
     exchanged, refunded or refinanced, (B) shall have an Average Life
     equal to or greater than the remaining Average Life of the
     Indebtedness so exchanged, refunded or refinanced and (C) if the
     Indebtedness to be exchanged, refunded or refinanced is subordinated
     to the 2004 Notes, the Indebtedness so issued is subordinated to the
     2004 Notes in right of payment;

           (5)  Indebtedness of a Restricted Subsidiary issued in exchange
     for, or the proceeds of which are used to refund or refinance,
     Indebtedness of a Restricted Subsidiary issued in accordance with
     Subsection (a) of this Section, provided that (i) the principal
     amount (or accreted value in the case of Indebtedness issued at a
     discount) of the Indebtedness so issued shall not exceed the
     principal amount (or accreted value in the case of Indebtedness
     issued at a discount) of, premium, if any, and accrued but unpaid
     interest on, the Indebtedness so exchanged, refunded or refinanced
     and (ii) the Indebtedness so issued (A) shall not mature prior to the
     stated maturity of the Indebtedness so exchanged, refunded or
     refinanced and (B) shall have an Average Life equal to or greater
     than the remaining Average Life of the Indebtedness so exchanged,
     refunded or refinanced.

           (6)    Indebtedness of a Consolidated Subsidiary issued to
     acquire, develop, improve, construct or to provide working capital
     for a gas, oil or electric generation, exploration, production,
     distribution, storage or transmission facility and related assets,
     provided that such Indebtedness is without recourse to any assets of
     the Issuer, Consumers, Enterprises, CMS Generation, NOMECO,
     CMS Electric and Gas, CMS Gas Transmission and Storage, CMS MST or
     any other Designated Enterprises Subsidiary;

           (7)  Indebtedness of a Person existing at the time at which
     such person became a Subsidiary and not incurred in connection with,
     or in contemplation of, such Person becoming a Subsidiary.  Such
     Indebtedness shall be deemed to be incurred on the date the acquired
     Person becomes a Consolidated Subsidiary;

           (8)    Indebtedness issued by the Issuer not to exceed
     $150,000,000 in aggregate principal amount at any time; and

           (9)    Indebtedness of a Consolidated Subsidiary in respect of
     rate reduction bonds issued to recover electric restructuring
     transition costs of Consumers provided that such Indebtedness is
     without recourse to the assets of Consumers.

           SECTION 4.05.  LIMITATION ON RESTRICTED PAYMENTS.  (a) So long
as the 2004 Notes are Outstanding and until the 2004 Notes are rated BBB-
or above (or an equivalent rating) by Standard & Poor's and one Other
Rating Agency (or, if Standard & Poor's shall change its rating system, an
equivalent of such rating then employed by such organization), at which
time the Issuer will be permanently released from the provisions of this
Section 4.05, the Issuer shall not, and shall not permit any Restricted
Subsidiary of the Issuer, directly or indirectly, to (i) declare or pay
any dividend or make any distribution on the Capital Stock of the Issuer
to the direct or indirect holders of its Capital Stock (except dividends
or distributions payable solely in its Non-Convertible Capital Stock or in
options, warrants or other rights to purchase such Non-Convertible Capital
Stock and except dividends or distributions payable to the Issuer or a
Subsidiary), (ii) purchase, redeem or otherwise acquire or retire for
value any Capital Stock of the Issuer, or (iii) purchase, repurchase,
redeem, defease or otherwise acquire or retire for value, prior to
scheduled maturity or scheduled repayment thereof, any Subordinated
Indebtedness (any such dividend, distribution, purchase, redemption,
repurchase, defeasing, other acquisition or retirement being hereinafter
referred to as a "Restricted Payment") if at the time the Issuer or such
Subsidiary makes such Restricted Payment:

           (1)  an Event of Default, or an event that with the lapse of
     time or the giving of notice or both would constitute an Event of
     Default, shall have occurred and be continuing (or would result
     therefrom); or

           (2)  the aggregate amount of such Restricted Payment and all
     other Restricted Payments made since May 6, 1997 would exceed the sum
     of:

               (A)  $100,000,000;

               (B)  100% of Consolidated Net Income, accrued during the
           period (treated as one accounting period) from May 6, 1997 to
           the end of the most recent fiscal quarter ending at least 45
           days prior to the date of such Restricted Payment (or, in case
           such sum shall be a deficit, minus 100% of the deficit); and

               (C)  the aggregate Net Cash Proceeds received by the Issuer
           from the issue or sale of or contribution with respect to its
           Capital Stock subsequent to May 6, 1997.

For the purpose of determining the amount of any Restricted Payment not in
the form of cash, the amount shall be the fair value of such Restricted
Payment as determined in good faith by the Board of Directors, provided
that if the value of the non-cash portion of such Restricted Payment as
determined by the Board of Directors is in excess of $25 million, such
value shall be based on the opinion from a nationally recognized firm
experienced in the appraisal of similar types of transactions.

           (b)  The provisions of Section 4.05(a) shall not prohibit:

               (i)  any purchase or redemption of Capital Stock of the
           Issuer made by exchange for, or out of the proceeds of the
           substantially concurrent sale of, Capital Stock of the Issuer
           (other than Redeemable Stock or Exchangeable Stock); provided,
           however, that such purchase or redemption shall be excluded
           from the calculation of the amount of Restricted Payments;

               (ii)  dividends or other distributions paid in respect of
           any class of the Issuer's Capital Stock issued in respect of
           the acquisition of any business or assets by the Issuer or a
           Restricted Subsidiary if the dividends or other distributions
           with respect to such Capital Stock are payable solely from the
           net earnings of such business or assets;

               (iii)  dividends paid within 60 days after the date of
           declaration thereof if at such date of declaration such
           dividend would have complied with this Section; provided,
           however, that at the time of payment of such dividend, no Event
           of Default shall have occurred and be continuing (or result
           therefrom), and provided further, however, that such dividends
           shall be included (without duplication) in the calculation of
           the amount of Restricted Payments; or

               (iv)  payments pursuant to the Tax-Sharing Agreement.

           SECTION 4.06.  LIMITATION ON ASSET SALES.  So long as any of
the 2004 Notes are outstanding, the Issuer may not sell, transfer or
otherwise dispose of any property or assets of the Issuer, including
Capital Stock of any Consolidated Subsidiary, in one transaction or a
series of transactions in an amount which exceeds $50,000,000 (an "Asset
Sale") unless the Issuer shall (i) apply an amount equal to such excess
Net Cash Proceeds to permanently repay Indebtedness of a Consolidated
Subsidiary or Indebtedness of the Issuer which is pari passu with the 2004
Notes or (ii) invest an equal amount not so used in clause (i) in property
or assets of related business within 24 months after the date of the Asset
Sale (the "Application Period") or (iii) apply such excess Net Cash
Proceeds not so used in (i) or (ii) (the "Excess Proceeds") to make an
offer, within 30 days after the end of the Application Period, to purchase
from the Holders on a pro rata basis an aggregate principal amount of 2004
Notes on the relevant purchase date equal to the Excess Proceeds on such
date, at a purchase price equal to 100% of the principal amount of the
2004 Notes on the relevant purchase date and unpaid interest, if any, to
the purchase date.  The Issuer shall only be required to make an offer to
purchase 2004 Notes from Holders pursuant to subsection (iii) if the
Excess Proceeds equal or exceed $25,000,000 at any given time.

           The procedures to be followed by the Issuer in making an offer
to purchase 2004 Notes from the Holders with Excess Proceeds, and for the
acceptance of such offer by the Holders, shall be the same as those set
forth in Section 3.01 herein with respect to a Change in Control.


  


                                 ARTICLE V
                       ADDITIONAL EVENTS OF DEFAULT
                      WITH RESPECT TO THE 2004 Notes

           SECTION 5.01.  DEFINITION.  All of the events specified in
clauses (a) through (h) of Section 5.1 of the Original Indenture shall be
"Events of Default" with respect to the 2004 Notes.

           SECTION 5.02.  AMENDMENTS TO SECTION 5.1 OF THE ORIGINAL
INDENTURE.  Solely for the purpose of determining Events of Default with
respect to the 2004 Notes, paragraphs (e), (f) and (h) of Section 5.1 of
the Original Indenture shall be amended such that each and every reference
therein to the Issuer shall be deemed to mean either the Issuer or
Consumers.


                                ARTICLE VI

                               GLOBAL NOTES

           The 2004 Notes will be issued initially in the form of Global
Notes.  "Global Note" means a registered 2004 Note evidencing one or more
2004 Notes issued to a depositary (the "Depositary") or its nominee, in
accordance with this Article and bearing the legend prescribed in this
Article.  One or more Global Notes will represent all 2004 Notes.  The
Issuer shall execute and the Trustee shall, in accordance with this
Article and the Issuer Order with respect to the 2004 Notes, authenticate
and deliver one or more Global Notes in temporary or permanent form that
(i) shall represent and shall be denominated in an aggregate amount equal
to the aggregate principal amount of the 2004 Notes to be represented by
such Global Note or Notes, (ii) shall be registered in the name of the
Depositary for such Global Note or Notes or the nominee of such
Depositary, (iii) shall be delivered by the Trustee to such Depositary or
pursuant to such Depositary's instructions and (iv) shall bear a legend
substantially to the following effect: "Unless the Global 2004 Note is
presented by an authorized representative of the Depository to the Issuer
or its agent for registration of transfer, exchange or payment, and any
2004 Note issued is registered in the name of a nominee of the Depository,
or in such other name as is requested by an authorized representative of
the Depository (and any payment is made to the nominee of the Depository,
or to such other entity as is requested by an authorized representative of
the Depository), any transfer, pledge or other use hereof for value or
otherwise by or to any Person is wrongful inasmuch as the registered owner
hereof has an interest herein."

           Notwithstanding Section 2.8 of the Indenture, unless and until
it is exchanged in whole or in part for 2004 Notes in definitive form, a
Global Note representing one or more 2004 Notes may not be transferred
except as a whole by the Depositary, to a nominee of such Depositary or by
a nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any such nominee to a successor
Depositary for 2004 Notes or a nominee of such successor Depositary.

           If at any time the Depositary for the 2004 Notes is unwilling
or unable to continue as Depositary for the 2004 Notes, the Issuer shall
appoint a successor Depositary with respect to the 2004 Notes.  If a
successor Depositary for the 2004 Notes is not appointed by the Issuer by
the earlier of (i) 90 days from the date the Issuer receives notice to the
effect that the Depositary is unwilling or unable to act, or the Issuer
determines that the Depositary is unable to act or (ii) the effectiveness
of the Depositary's resignation or failure to fulfill its duties as
Depositary, the Issuer will execute, and the Trustee, upon receipt of a
Issuer Order for the authentication and delivery of definitive 2004 Notes,
will authenticate and deliver 2004 Notes in definitive form in an
aggregate principal amount equal to the principal amount of the Global
Note or Notes representing such 2004 Notes in exchange for such Global
Note or Notes.

           The Issuer may at any time and in its sole discretion determine
that the 2004 Notes issued in the form of one or more Global Notes shall
no longer be represented by such Global Note or Notes.  In such event the
Issuer will execute, and the Trustee, upon receipt of a Issuer Order for
the authentication and delivery of definitive 2004 Notes, will
authenticate and deliver 2004 Notes in definitive form in an aggregate
principal amount equal to the principal amount of the Global Note or Notes
representing such 2004 Notes in exchange for such Global Note or Notes.

           The Depositary for such 2004 Notes may surrender a Global Note
or Notes for such 2004 Notes in exchange in whole or in part for 2004
Notes in definitive form on such terms as are acceptable to the Issuer and
such Depositary.  Thereupon, the Issuer shall execute, and the Trustee
shall authenticate and deliver, without service charge:

              (i)  to each Person specified by such Depositary a new 2004
           Note or Notes, of any authorized denomination as requested by
           such Person in aggregate principal amount equal to and in
           exchange for such Person's beneficial interest in the Global
           Note; and

              (ii)  to such Depositary a new Global Note in a denomination
           equal to the difference, if any, between the principal amount
           of the surrendered Global Note and the aggregate principal
           amount of 2004 Notes in definitive form delivered to Holders
           thereof.

           In any exchange provided for in this Article, the Issuer will
execute and the Trustee will authenticate and deliver 2004 Notes in
definitive registered form in authorized denominations.

           Upon the exchange of a Global Note for 2004 Notes in definitive
form, such Global Note shall be cancelled by the Trustee.  2004 Notes in
definitive form issued in exchange for a Global Note pursuant to this
Article shall be registered in such names and in such authorized
denominations as the Depositary for such Global Note, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee or Security Registrar.  The Trustee shall deliver
such 2004 Notes to the persons in whose names such 2004 Notes are so
registered.


                                ARTICLE VII

                                DEFEASANCE

           All of the provisions of Article Ten of the Original Indenture
shall be applicable to the 2004 Notes.  Upon satisfaction by the Issuer of
the requirements of Section 10.1(c) of the Indenture, in connection with
any covenant defeasance (as provided in Section 10.1(c) of the Indenture),
the Issuer shall be released from its obligations under Article Nine of
the Original Indenture and under Articles III and IV of this Fourth
Supplemental Indenture with respect to the 2004 Notes.


                               ARTICLE VIII
                          SUPPLEMENTAL INDENTURES

           This Fourth Supplemental Indenture is a supplement to the
Original Indenture.  As supplemented by this Fourth Supplemental
Indenture, the Original Indenture is in all respects ratified, approved
and confirmed, and the Original Indenture and this Fourth Supplemental
Indenture shall together constitute one and the same instrument.


                                TESTIMONIUM

           This Fourth Supplemental Indenture may be executed in any
number of counterparts, each of which so executed shall be deemed to be an
original, but all such counterparts shall together constitute but one and
the same instrument.


  


           IN WITNESS WHEREOF, the parties hereto have caused this Fourth
Supplemental Indenture to be duly executed and their respective corporate
seals to be hereunto affixed and attested, all as of the day and year
first written above.
