                             UNDERWRITING AGREEMENT
 
                                                                   June   , 1995
 
To the Representatives named in
Schedule I hereto of the Underwriters
  named in Schedule II hereto
 
Dear Sirs:
 
     CMS Energy Corporation, a Michigan corporation (the "Company"), proposes to
issue and sell to the several Underwriters (as defined in Section 14 hereof)
8,000,000 shares of its Class G Common Stock (no par value) (the "Firm
Securities") as indicated in Schedule II. The Company also proposes to issue and
sell to the several Underwriters not more than           shares of its Class G
Common Stock (no par value) (the "Additional Securities") if and to the extent
that the Representatives (as defined in Section 14 hereof) shall have determined
to exercise, on behalf of the Underwriters, the right to purchase such shares of
common stock granted to the Underwriters in Section 1 hereof. The Firm
Securities and the Additional Securities are hereinafter collectively referred
to as the "Securities." The Underwriters have designated the Representatives to
execute this Agreement on their behalf and to act for them in the manner
provided in this Agreement.
 
     The Company has prepared and filed with the Securities and Exchange
Commission (the "Commission"), in accordance with the provisions of the
Securities Act of 1933, as amended (the "Act"), a registration statement on Form
S-3 (Registration Nos. 33-57719 and 33-57719-01) including a prospectus relating
to the Securities and certain amendments to such registration statement, and
such registration statement, as so amended, has become effective under the Act.
The registration statement, as amended by a post-effective amendment No. 1
thereto, at the time such registration statement, as so amended, became
effective and as it may have been thereafter amended to the date of this
Agreement (including the documents then incorporated by reference therein) is
hereinafter referred to as the "Registration Statement." The prospectus forming
a part of the Registration Statement at the time the Registration Statement
became effective (including the documents then incorporated by reference
therein) is hereinafter referred to as the "Basic Prospectus," provided that in
the event that the Basic Prospectus shall have been amended, revised or
supplemented prior to the date of this Agreement, or if the Company shall have
supplemented the Basic Prospectus by filing any documents pursuant to Section 13
or 14 or 15 of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), after the time the Registration Statement became effective and prior to
the date of this Agreement, which documents are deemed to be incorporated in the
Basic Prospectus, the term "Basic Prospectus" shall also mean such prospectus as
so amended, revised or supplemented. The Basic Prospectus, as it shall be
revised or supplemented to reflect the final terms of the offering and sale of
the Securities and in the form to be filed with, or transmitted for filing to,
the Commission pursuant to Rule 424 under the Act, is hereinafter referred to as
the "Prospectus." Any reference herein to the terms "amend," " amendment" or
"supplement" with respect to the Registration Statement or the Prospectus shall
be deemed to include only amendments or supplements to the Registration
Statement or Prospectus, as the case may be, and documents incorporated by
reference therein after the date of this Agreement and prior to the termination
of the offering of the Securities by the Underwriters.
 
     1. Purchase and Sale:  Upon the basis of the representations and warranties
and on the terms and subject to the conditions herein set forth, the Company
agrees to sell to the respective Underwriters, severally and not jointly, and
the respective Underwriters, severally and not jointly, agree to purchase from
the
   2
 
Company, at the purchase price of $          a share (the "Purchase Price"), the
respective number of shares of Firm Securities set opposite their names in
Schedule II hereto.
 
     In addition, on the basis of the representations and warranties and on the
terms and subject to the conditions herein set forth, the Company agrees to sell
to the Underwriters, and the Underwriters shall have a one-time right to
purchase, severally and not jointly, up to           shares of Additional
Securities at the Purchase Price. Additional Securities may be purchased as
provided in Section 2 hereof solely for the purpose of covering over-allotments
made in connection with the offering of the Firm Securities. If any Additional
Securities are to be purchased, each Underwriter agrees, severally and not
jointly, to purchase the number of shares of Additional Securities (subject to
such adjustments to eliminate fractional shares as the Representatives may
determine) that bears the same proportion to the total number of shares of
Additional Securities to be purchased as the number of shares of Firm Securities
set forth in Schedule II opposite the name of such Underwriter bears to the
total number of shares of Firm Securities.
 
     The Company hereby agrees that, without the prior written consent of Morgan
Stanley & Co. Incorporated, the Company will not offer, sell, contract to sell
or otherwise dispose of any shares of (a) Class G Common Stock of the Company or
any securities (other than Common Stock, par value $.01 per share, of the
Company (the "CMS Energy Common Stock")) convertible into or exercisable or
exchangeable for Class G Common Stock of the Company other than the Securities
for a period of 180 days after the date of this Agreement or (b) CMS Energy
Common Stock or any securities convertible into or exercisable or exchangeable
for CMS Energy Common Stock for a period of 90 days after the date of this
Agreement; provided that the Company may, during such period, (i) in a manner
generally consistent with past practices regarding the numbers of shares issued
by the Company from time to time thereunder, issue shares of CMS Energy Common
Stock and Class G Common Stock under its Dividend Reinvestment and Optional Cash
Payment Plan, Performance Incentive Stock Plan, Employee Stock Ownership Plan
and Employee Savings and Incentive Plan, as any of the same may be supplemented
or amended and (ii) issue up to 3,000,000 shares of CMS Energy Common Stock
solely for the purpose of effecting acquisitions of other businesses or
properties.
 
     The Company is advised by the Representatives that the Underwriters propose
to make a public offering of their respective portions of the Securities as soon
as this Agreement has become effective. The Company is further advised by the
Representatives that the Securities are to be offered to the public initially at
$          a share (the public offering price) and to certain dealers selected
by you at a price that represents a concession not in excess of $          a
share under the public offering price, and that any Underwriter may allow, and
such dealers may allow, a concession, not in excess of $          a share, to
certain other dealers.
 
     2. Payment and Delivery:  Payment for the Firm Securities shall be made to
the Company or its order by bank check or checks, as requested by the Company,

Underwriters for the respective number of shares of Firm Securities, set forth
opposite the name of each Underwriter in Schedule II, and in the case of
Additional Securities, for the respective number of shares determined in
accordance with Section 1 hereof, in each case in denominations selected by the
Company.

     in case any Underwriter is required to deliver a prospectus after the
     expiration of nine months after the date of the Prospectus, to furnish to

     or supplement to the Prospectus and deliver to the Underwriters, without
     charge, such number of copies thereof as may be reasonably requested.

     expenses of the Underwriters in connection with their services hereunder.

     6. Representations and Warranties of the Company:  The Company represents
and warrants to, and agrees with, each of the Underwriters that:
 
          (a) The Registration Statement has become effective under the Act; a
     true and correct copy of the Registration Statement in the form in which it
     became effective has been delivered to each of the Representatives and to
     the Representatives for each of the Underwriters (except that copies
     delivered for the Underwriters excluded exhibits to such Registration
     Statement); any filing of the Prospectus and any supplements thereto
     required pursuant to Rule 424(b) have been or will be made in the manner
     required by Rule 424(b) and within the time period required by Section 3(j)
     hereof; no stop order suspending the effectiveness of the Registration
     Statement is in effect, and no proceedings for such purposes are pending
     before or, to the knowledge of the Company, threatened by the Commission.
     On the effective date of the Registration Statement, the Registration
     Statement and the Basic Prospectus complied, or were deemed to have
     complied, and on its respective issue date, each preliminary prospectus
     filed pursuant to Rule 424(b) complied, and the Basic Prospectus complied,
     and on its issue date, the Prospectus will comply, or will be deemed to
     comply, in all material respects with the applicable provisions of the Act
     and the published rules and regulations of the Commission; none of the
     Registration Statement on its effective date, the Basic Prospectus on its
     issue date, or any other preliminary prospectus, on its issue date,
     contained any untrue statement of a material fact or omitted to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, and the Prospectus, as of its issue date
     and, as amended or supplemented, if applicable, as of the First Time of
     Purchase and Second Time of Purchase, will not contain any untrue statement
     of a material fact or omit to state a material fact necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading, except that the Company makes no warranty or
     representation to any Underwriter with respect to any statements or
     omissions made therein in reliance upon and in conformity with information
 
                                        6
   7
 
     furnished in writing to the Company by, or through the Representatives on
     behalf of, any Underwriter expressly for use therein.
 
          (b) The documents incorporated by reference in the Registration
     Statement, any preliminary prospectus, the Basic Prospectus and the
     Prospectus, when they were filed (or, if an amendment with respect to any
     such document was filed, when such amendment was filed) with the
     Commission, conformed in all material respects to the requirements of the
     Exchange Act and the rules and regulations of the Commission promulgated
     thereunder, and any further documents so filed and incorporated by
     reference will, when they are filed with the Commission, conform in all
     material respects to the requirements of the Exchange Act and the rules and
     regulations of the Commission promulgated thereunder; none of such
     documents, when it was filed (or, if an amendment with respect to any such
     document was filed, when such amendment was filed), contained an untrue
     statement of a material fact or omitted to state a material fact required
     to be stated therein or necessary to make the statements therein, in light
     of the circumstances under which they were made, not misleading; and no
     such further document, when it is filed, will contain an untrue statement
     of a material fact or will omit to state a material fact required to be
     stated therein or necessary to make the statements therein, in light of the
     circumstances under which they are made, not misleading.
 
          (c) The Company has been duly organized and is validly existing as a
     corporation in good standing under the laws of the State of Michigan and
     has all requisite authority to own or lease its properties and conduct its
     business as described in the Prospectus and to consummate the transactions
     contemplated hereby, and is duly qualified to transact business and is in
     good standing in each jurisdiction in which the conduct of its business as
     described in the Prospectus or its ownership or leasing of property
     requires such qualification, except to the extent that the failure to be so
     qualified or be in good standing would not have a material adverse effect
     on the Company and its Subsidiaries taken as a whole. Each significant
     subsidiary (as defined in Rule 405 under the Act, and hereinafter called a
     "Significant Subsidiary") of the Company has been duly organized and is
     validly existing as a corporation in good standing under the laws of the
     jurisdiction of its incorporation, has all requisite authority to own or
     lease its properties and conduct its business as described in the
     Prospectus and is duly qualified to transact business and is in good
     standing in each jurisdiction in which the conduct of its business as
     described in the Prospectus or its ownership or leasing of property
     requires such qualification, except to the extent that the failure to be so
     qualified or be in good standing would not have a material adverse effect
     on the Company and its Subsidiaries, taken as a whole.
 
          (d) The pro forma consolidated condensed balance sheets and
     consolidated and condensed statements of income and the related notes
     thereto set forth or included or incorporated by reference in the
     Registration Statement and the Prospectus with respect to the Company and
     the Consumers Gas Group have been prepared in accordance with the
     applicable requirements of Regulation S-X promulgated under the Exchange
     Act, have been compiled on the pro forma basis described therein and, in
     the opinion of the Company, the assumptions used in the preparations
     thereof were reasonable at the time made and the adjustments used therein
     are based upon good faith estimates and assumptions believed by the Company
     to be reasonable at the time made.
 
          (e) The shares of Common Stock of the Company outstanding prior to the
     issuance of the Securities have been duly authorized and are validly
     issued, fully paid and non-assessable.
 
          (f) The Company's Articles of Incorporation and all amendments thereto
     to date, including, without limitation, the amendments necessary to create
     the Class G Common Stock (no par value) of the Company as described in the
     Registration Statement, have been duly authorized and all necessary
     corporate and shareholder action and all necessary filings pursuant to the
     laws of the State of Michigan in connection therewith have been taken,
     obtained or made.
 
          (g) The Securities have been duly authorized and, when issued and
     delivered in accordance with the terms of this Agreement, will be validly
     issued, fully paid and nonassessable, and the issuance of such Securities
     will not be subject to any preemptive or similar rights.
 
                                        7
   8
 
          (h) The capital stock of the Company conforms in all material respects
     to the description thereof in the Prospectus.
 
          (i) Except for the outstanding shares of preferred stock of Consumers
     Power Company, all of the outstanding capital stock of each of Consumers
     Power Company, CMS Enterprises Company, CMS NOMECO Oil & Gas Co., and
     Michigan Gas Storage Company is owned directly or indirectly by the
     Company, free and clear of any security interest, claim, lien, or other
     encumbrance or preemptive rights, and (ii) there are no outstanding rights
     (including, without limitation, preemptive rights), warrants or options to
     acquire, or instruments convertible into or exchangeable for, any shares of
     capital stock or other equity interest in any of Consumers Power Company,
     CMS Enterprises Company, CMS NOMECO Oil & Gas Co., and Michigan Gas Storage
     Company or any contract, commitment, agreement, understanding or
     arrangement of any kind relating to the issuance of any such capital stock,
     any such convertible or exchangeable securities or any such rights,
     warrants or options.
 
          (j) Each of the Company and its Significant Subsidiaries has all
     necessary consents, authorizations, approvals, orders, certificates and
     permits of and from, and has made all declarations and filings with, all
     federal, state, local and other governmental authorities, all
     self-regulatory organizations and all courts and other tribunals, to own,
     lease, license and use its properties and assets and to conduct its
     business in the manner described in the Prospectus, except to the extent
     that the failure to obtain or file would not have a material adverse effect
     on the Company and its Subsidiaries, taken as a whole.
 
          (k) No order, license, consent, authorization or approval of, or
     exemption by, or the giving of notice to, or the registration with any
     federal, state, municipal or other governmental department, commission,
     board, bureau, agency or instrumentality, and no filing, recording,
     publication or registration in any public office or any other place, was or
     is now required to be obtained by the Company to authorize its execution or
     delivery of, or the performance of its obligations under, this Agreement or
     the Securities, except such as have been obtained or may be required under
     state securities or Blue Sky laws or as referred to in the Basic
     Prospectus. Each of the Company and its Significant Subsidiaries has all
     necessary consents, authorizations, approvals, orders, certificates and
     permits of and from, and has made all declarations and filings with, all
     federal, state, local and other governmental authorities, all
     self-regulatory organizations and all courts and other tribunals, to own,
     lease, license and use its properties and assets and to conduct its
     business in the manner described in the Basic Prospectus, except to the
     extent that the failure to obtain or file would not have a material adverse
     effect on the Company and its Subsidiaries, taken as a whole.
 
          (l) Neither the execution or delivery by the Company of, nor the
     performance by the Company of its obligations under, this Agreement did or
     will conflict with, result in a breach of any of the terms or provisions
     of, or constitute a default or require the consent of any party under the
     Company's Articles of Incorporation or by-laws, any material agreement or
     instrument to which it is a party, any existing applicable law, rule or
     regulation or any judgment, order or decree of any government, governmental
     instrumentality or court, domestic or foreign, having jurisdiction over the
     Company or any of its properties or assets, or did or will result in the
     creation or imposition of any lien on the Company's properties or assets.
 
          (m) Except as disclosed in the Basic Prospectus, there is no action,
     suit, proceeding, inquiry or investigation (at law or in equity or
     otherwise) pending or, to the knowledge of the Company, threatened against
     the Company or any Subsidiary by any governmental authority that (i)
     questions the validity, enforceability or performance of this Agreement or
     the Securities or (ii) if determined adversely, is likely to have a
     material adverse effect on the business or financial condition of the
     Company and its Subsidiaries, taken as a whole, or of the Consumers Gas
     Group or materially adversely affect the ability of the Company to perform
     its obligations hereunder or the consummation of the transactions
     contemplated by this Agreement.
 
          (n) There has not been any material and adverse change in the
     business, properties or financial condition of (i) the Company and its
     Subsidiaries, taken as a whole, or (ii) the Consumers Gas Group,
 
                                        8
   9
 
     from that set forth in the Registration Statement (other than changes
     referred to in or contemplated by the Registration Statement or the Basic
     Prospectus).
 
          (o) Except as set forth in the Basic Prospectus, no event or condition
     exists that constitutes, or with the giving of notice or lapse of time or
     both would constitute, a default or any breach or failure to perform by the
     Company or any of its Significant Subsidiaries in any material respect
     under any indenture, mortgage, loan agreement, lease or other material
     agreement or instrument to which the Company or any of its Significant
     Subsidiaries is a party or by which it or any of its Significant
     Subsidiaries, or any of their respective properties, may be bound.
 
     7. Representation and Warranties of Underwriters:  Each Underwriter
warrants and represents that the information, if any, furnished in writing to
the Company through the Representatives expressly for use in the Registration
Statement and Prospectus is correct in all material respects as to such
Underwriter. Each Underwriter, in addition to other information furnished to the
Company for use in the Registration Statement and Prospectus, herewith furnishes
to the Company for use in the Registration Statement and Prospectus, the
information stated herein with regard to the public offering, if any, by such
Underwriter and represents and warrants that such information is correct in all
material respects as to such Underwriter.
 
     8. Indemnification:
 
          (a) The Company agrees, to the extent permitted by law, to indemnify
     and hold harmless each of the Underwriters and each person, if any, who
     controls any such Underwriter within the meaning of Section 15 of the Act
     or Section 20 of the Exchange Act, against any and all losses, claims,
     damages or liabilities, joint or several, to which they or any of them may
     become subject under the Act or otherwise, and to reimburse the
     Underwriters and such controlling person or persons, if any, for any legal
     or other expenses incurred by them in connection with defending any action,
     suit or proceeding (including governmental investigations) as provided in
     Section 8(b) hereof, insofar as such losses, claims, damages, liabilities
     or actions, suits or proceedings (including governmental investigations)
     arise out of or are based upon any untrue statement or alleged untrue
     statement of a material fact contained in the Registration Statement, any
     preliminary prospectus as of its issue date (if used prior to the date of
     the Basic Prospectus), the Basic Prospectus (if used prior to the date of
     the Prospectus), the Prospectus, or, if the Prospectus shall be amended or
     supplemented, in the Prospectus as so amended or supplemented (if such
     Prospectus or such Prospectus as amended or supplemented is used after the
     period of time referred to in Section 5(e) hereof, it shall contain or be
     used with such amendments or supplements as the Company deems necessary to
     comply with Section 10(a) of the Act), or arise out of or are based upon
     any omission or alleged omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading, except insofar as such losses, claims, damages, liabilities or
     actions arise out of or are based upon any such untrue statement or alleged
     untrue statement or omission or alleged omission which was made in such
     preliminary prospectus, Basic Prospectus, Registration Statement or
     Prospectus, or in the Prospectus as so amended or supplemented, in reliance
     upon and in conformity with information furnished in writing to the Company
     by, or through the Representatives on behalf of, any Underwriter expressly
     for use therein, and except that this indemnity shall not inure to the
     benefit of any Underwriter (or any person controlling such Underwriter) on
     account of any losses, claims, damages, liabilities or actions, suits or
     proceedings arising from the sale of the Securities to any person if a copy
     of the Prospectus, as the same may then be supplemented or amended
     (excluding, however, any document then incorporated or deemed incorporated
     therein by reference), was not sent or given by or on behalf of such
     Underwriter to such person (i) with or prior to the written confirmation of
     sale involved or (ii) as soon as available after such written confirmation,
     relating to an event occurring prior to the payment for and delivery to
     such person of the Securities involved in such sale, and the omission or
     alleged omission or untrue statement or alleged untrue statement was
     corrected in the Prospectus as supplemented or amended at such time.
 
          The Company's indemnity agreement contained in this Section 8(a), and
     the covenants, representations and warranties of the Company contained in
     this Agreement, shall remain in full force and effect regardless of any
     investigation made by or on behalf of any person, and shall survive the
     delivery of and
 
                                        9
   10
 
     payment for the Securities hereunder, and the indemnity agreement contained
     in this Section 8 shall survive any termination of this Agreement. The
     liabilities of the Company in this Section 8(a) are in addition to any
     other liabilities of the Company under this Agreement or otherwise.
 
          (b) Each Underwriter agrees, severally and not jointly, to the extent
     permitted by law, to indemnify, hold harmless and reimburse the Company,
     its directors and such of its officers as shall have signed the
     Registration Statement, each other Underwriter and each person, if any, who
     controls the Company or any such other Underwriter within the meaning of
     Section 15 of the Act or Section 20 of the Exchange Act, to the same extent
     and upon the same terms as the indemnity agreement of the Company set forth
     in Section 8(a) hereof, but only with respect to alleged untrue statements
     or omissions made in the Registration Statement, the Basic Prospectus or in
     the Prospectus, as amended or supplemented, (if applicable) in reliance
     upon and in conformity with information furnished in writing to the Company
     by such Underwriter expressly for use therein.
 
          The indemnity agreement on the part of each Underwriter contained in
     this Section 8(b) and the representations and warranties of such
     Underwriter contained in this Agreement shall remain in full force and
     effect regardless of any investigation made by or on behalf of the Company
     or any other person, and shall survive the delivery of and payment for the
     Securities hereunder, and the indemnity agreement contained in this Section
     8(b) shall survive any termination of this Agreement. The liabilities of
     each Underwriter in Section 8(b) are in addition to any other liabilities
     of such Underwriter under this Agreement or otherwise.
 
          (c) If a claim is made or an action, suit or proceeding (including
     governmental investigations) is commenced or threatened against any person
     as to which indemnity may be sought under Section 8(a) or 8(b), such person
     (the "Indemnified Person") shall notify the person against whom such
     indemnity may be sought (the "Indemnifying Person") promptly after any
     assertion of such claim threatening to institute an action, suit or
     proceeding or if such an action, suit or proceeding is commenced against
     such Indemnified Person, promptly after such Indemnified Person shall have
     been served with a summons or other first legal process, giving information
     as to the nature and basis of the claim. Failure to so notify the
     Indemnifying Person shall not, however, relieve the Indemnifying Person
     from any liability which it may have on account of the indemnity under
     Section 8(a) or 8(b) if the Indemnifying Person has not been prejudiced in
     any material respect by such failure. The Indemnifying Person shall assume
     the defense of any such litigation or proceeding, including the employment
     of counsel and the payment of all expenses. Such counsel shall be
     designated in writing by the Representatives in the case of parties
     indemnified pursuant to Section 8(b) and by the Company in the case of
     parties indemnified pursuant to Section 8(a). Any Indemnified Person shall
     have the right to participate in such litigation or proceeding and to
     retain its own counsel, but the fees and expenses of such counsel shall be
     at the expense of such Indemnified Person unless (i) the Indemnifying
     Person and the Indemnified Person shall have mutually agreed to the
     retention of such counsel or (ii) the named parties to any such proceeding
     (including any impleaded parties) include (x) the Indemnifying Person and
     (y) the Indemnified Person and, in the written opinion of counsel to such
     Indemnified Person, representation of both parties by the same counsel
     would be inappropriate due to actual or likely conflicts of interest
     between them, in either of which cases the reasonable fees and expenses of
     counsel (including disbursements) for such Indemnified Person shall be
     reimbursed by the Indemnifying Person to the Indemnified Person. If there
     is a conflict as described in clause (ii) above, and the Indemnified
     Persons have participated in the litigation or proceeding utilizing
     separate counsel whose fees and expenses have been reimbursed by the
     Indemnifying Person and the Indemnified Persons, or any of them, are found
     to be solely liable, such Indemnified Persons shall repay to the
     Indemnifying Person such fees and expenses of such separate counsel as the
     Indemnifying Person shall have reimbursed. It is understood that the
     Indemnifying Person shall not, in connection with any litigation or
     proceeding or related litigation or proceedings in the same jurisdiction as
     to which the Indemnified Persons are entitled to such separate
     representation, be liable under this Agreement for the reasonable fees and
     out-of-pocket expenses of more than one separate firm (together with not
     more than one appropriate local counsel) for all such Indemnified Persons.
     Subject to the next paragraph, all such
 
                                       10
   11
 
     fees and expenses shall be reimbursed by payment to the Indemnified Persons
     of such reasonable fees and expenses of counsel promptly after payment
     thereof by the Indemnified Persons.
 
     In furtherance of the requirement above that fees and expenses of any
separate counsel for the Indemnified Persons shall be reasonable, the
Representatives and the Company agree that the Indemnifying Person's obligations
to pay such fees and expenses shall be conditioned upon the following:
 
          (1) in case separate counsel is proposed to be retained by the
     Indemnified Persons pursuant to clause (ii) of the preceding paragraph, the
     Indemnified Persons shall in good faith fully consult with the Indemnifying
     Person in advance as to the selection of such counsel; and
 
          (2) reimbursable fees and expenses of such separate counsel shall be
     detailed and supported in a manner reasonably acceptable to the
     Indemnifying Person (but nothing herein shall be deemed to require the
     furnishing to the Indemnifying Person of any information, including without
     limitation, computer print-outs of lawyers' daily time entries, to the
     extent that, in the judgment of such counsel, furnishing such information
     might reasonably be expected to result in a waiver of any attorney-client
     privilege); and
 
          (3) the Company and the Representatives shall cooperate in monitoring
     and controlling the fees and expenses of separate counsel for Indemnified
     Persons for which the Indemnifying Person is liable hereunder, and the
     Indemnified Person shall use every reasonable effort to cause such separate
     counsel to minimize the duplication of activities as between themselves and
     counsel to the Indemnifying Person.
 
     The Indemnifying Person shall not be liable for any settlement of any
litigation or proceeding effected without the written consent of the
Indemnifying Person, but if settled with such consent or if there be a final
judgment for the plaintiff, the Indemnifying Person agrees, subject to the
provisions of this Section 8, to indemnify the Indemnified Person from and
against any loss, damage, liability or expenses by reason of such settlement or
judgment. The Indemnifying Person shall not, without the prior written consent
of the Indemnified Persons, effect any settlement of any pending or threatened
litigation, proceeding or claim in respect of which indemnity has been properly
sought by the Indemnified Persons hereunder, unless such settlement includes an
unconditional release by the claimant of all Indemnified Persons from all
liability with respect to claims which are the subject matter of such
litigation, proceeding or claim.
 
     9. Contribution:  If the indemnification provided for in Section 8 above is
unavailable to or insufficient to hold harmless an Indemnified Person under such
Section in respect of any losses, claims, damages or liabilities (or actions,
suits or proceedings (including governmental investigations) in respect thereof)
referred to therein, then each Indemnifying Person under Section 8 shall
contribute to the amount paid or payable by such Indemnified Person as a result
of such losses, claims, damages or liabilities (or actions in respect thereof)
in such proportion as is appropriate to reflect the relative benefits received
by the Indemnifying Person on the one hand and the Indemnified Person on the
other from the offering of the Securities. If, however, the allocation provided
by the immediately preceding sentence is not permitted by applicable law, then
each Indemnifying Person shall contribute to such amount paid or payable by such
Indemnified Person in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of each Indemnifying Person, if
any, on the one hand and the Indemnified Person on the other in connection with
the statements or omissions which resulted in such losses, claims, damages or
liabilities (or actions, suits or proceedings (including governmental
investigations) in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering (before deducting expenses) received
by the Company and the total underwriting discounts and commission received by
the Underwriters, in each case as set forth in the table on the cover page of
the Prospectus, bear to the aggregate public offering price of the Securities.
The relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company on the one hand or the Underwriters on the other and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Company and the Underwriters
agree that it would not be just and equitable if contribution pursuant to this
Section 9 were determined by pro rata allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
which does not
 
                                       11
   12
 
take account of the equitable considerations referred to above in this Section
9. The amount paid or payable by an Indemnified Person as a result of the
losses, claims, damages or liabilities (or actions, suits or proceedings
(including governmental proceedings) in respect thereof) referred to above in
this Section 9 shall be deemed to include any legal or other expenses reasonably
incurred by such Indemnified Person in connection with investigating or
defending any such action, suits or proceedings (including governmental
proceedings) or claim, provided that the provisions of Section 8 have been
complied with (in all material respects) in respect of any separate counsel for
such Indemnified Person. Notwithstanding the provisions of this Section 9, no
Underwriter shall be required to contribute any amount greater than the excess
of (i) the total price at which the Securities underwritten by it and
distributed to the public were offered to the public over (ii) the amount of any
damages which such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Underwriters' obligations in
this Section 9 to contribute are several in proportion to their respective
underwriting obligations and not joint.
 
     The agreement with respect to contribution contained in Section 9 hereof
shall remain in full force and effect regardless of any investigation made by or
on behalf of the Company or any Underwriter, and shall survive delivery of and
payment for the Securities hereunder and any termination of this Agreement.
 
     10. Substitution of Underwriters:  If any Underwriter under this agreement
shall fail or refuse (otherwise than for some reason sufficient to justify in
accordance with the terms hereof, the termination of its obligations hereunder)
to purchase the Securities which it had agreed to purchase on the First Time of
Purchase or Second Time of Purchase, the Representatives shall immediately
notify the Company and the Representatives and the other Underwriters may,
within 36 hours of the giving of such notice, determine to purchase, or to
procure one or more other members of the National Association of Securities
Dealers, Inc. ("NASD") (or, if not members of the NASD, who are foreign banks,
dealers or institutions not registered under the Securities Exchange Act and who
agree in making sales to comply with the NASD's Rules of Fair Practice),
satisfactory to the Company, to purchase, upon the terms herein set forth, the
number of shares of Securities which the defaulting Underwriter had agreed to
purchase. If any non-defaulting Underwriter or Underwriters shall determine to
exercise such right, the Representatives shall give written notice to the
Company of such determination within 36 hours after the Company shall have
received notice of any such default, and thereupon the First Time of Purchase or
Second Time of Purchase, as the case may be, shall be postponed for such period,
not exceeding three business days, as the Company shall determine. If in the
event of such a default, the Representatives shall fail to give such notice, or
shall within such 36-hour period give written notice to the Company that no
other Underwriter or Underwriters, or others, will exercise such right, then
this Agreement may be terminated by the Company, upon like notice given to the
Representatives within a further period of 36 hours. If in such case the Company
shall not elect to terminate this Agreement, it shall have the right,
irrespective of such default:
 
          (a) to require such non-defaulting Underwriters to purchase and pay
     for the respective number of shares which they had severally agreed to
     purchase hereunder, as hereinabove provided, and, in addition, the number
     of shares of Securities which the defaulting Underwriter shall have so
     failed to purchase up to a number of shares thereof equal to one-ninth
     (1/9) of the respective number of shares of Securities which such
     non-defaulting Underwriters have otherwise agreed to purchase hereunder;
     and/or
 
          (b) to procure one or more other members of the NASD (or, if not
     members of the NASD, who are foreign banks, dealers or institutions not
     registered under the Exchange Act and who agree in making sales to comply
     with the NASD's Rules of Fair Practice), to purchase, upon the terms herein
     set forth, the number of shares of Securities which such defaulting
     Underwriter had agreed to purchase, or that portion thereof which the
     remaining Underwriters shall not be obligated to purchase pursuant to the
     foregoing clause (a).
 
     In the event the Company shall exercise its rights under clause (a) and/or
(b) above, the Company shall give written notice thereof to the Representatives
within such further period of 36 hours, and thereupon the First Time of Purchase
or the Second Time of Purchase shall be postponed for such period, not exceeding
five
 
                                       12
   13
 
business days, as the Company shall determine. In the event the Company shall be
entitled to but shall not elect to exercise its rights under clause (a) and/or
(b), the Company shall be deemed to have elected to terminate this Agreement.
 
     Any action taken by the Company under this Section 10 shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement. Termination by the Company under this Section
10 shall be without any liability on the part of the Company or any
non-defaulting Underwriter.
 
     In the computation of any period of 36 hours referred to in this Section
10, there shall be excluded a period of 24 hours in respect of each Saturday,
Sunday or legal holiday which would otherwise be included in such period of
time.
 
     11. Termination of Agreement:  This Agreement may be terminated at any time
prior to the First Time of Purchase, and the option referred to in Section 1
hereof, if exercised, may be canceled at any time prior to the Second Time of
Purchase, by the Representatives, if prior to such time (i) trading generally in
securities on the New York Stock Exchange shall have been suspended by the

by the Commission or the New York Stock Exchange or by any federal or state
agency or by the decision of any court any general limitation on prices for such
trading or any general restrictions on the distribution of securities, (ii)
trading of any securities of the Company or Consumers Power Company shall have

outbreak or material escalation of hostilities or any material adverse
disruption in financial markets or any calamity or crisis, the effect of which
on the financial markets of the United States is such as to impair, in the
Representatives' reasonable judgment, after having made due inquiry, the
marketability of the Securities.
 
     If the Representatives elect to terminate this Agreement, as provided in
this Section 11, the Representatives will promptly notify the Company and each
other Underwriter by telephone or telecopy, confirmed by letter. If this
Agreement shall not be carried out by any Underwriter for any reason permitted

with the terms hereof, the Company shall not be under any obligation under this
Agreement and shall not be liable to any Underwriter or to any member of any
selling group for the loss of anticipated profits from the transactions
contemplated by this Agreement and the Underwriters shall be under no liability
to the Company nor be under any liability under this Agreement to one another.

9 shall survive any termination of this Agreement.

           Re: CMS Energy Corporation
               8,000,000 Shares of Class G Common Stock (no par value)
 
Ladies and Gentlemen:
 
     I address this opinion to you individually and as Representatives of the
Underwriters (the "Underwriters"), named in Schedule II to the Underwriting
Agreement dated                , 1995 (the "Underwriting Agreement"), between
you, as such Representatives, and CMS Energy Corporation, a Michigan corporation
(the "Company"), with respect to the issuance and sale of up to 8,000,000 shares
(the "Securities") of the Company's Class G Common Stock, (no par value) (the
"Securities"). Capitalized terms not defined herein have the meanings specified
in the Underwriting Agreement.
 
     In rendering the opinions expressed below, I or attorneys acting under my
supervision have examined originals, or copies of originals certified to my
satisfaction, of such agreements, documents, certificates and other statements
of governmental officials and corporate officers and such other papers and
evidence as I or we have deemed relevant and necessary as a basis for such
opinions. We have assumed the authenticity of all documents submitted to us as
originals, the genuineness of all signatures, the legal capacity of all natural
persons, and the conformity with the original documents of any copies thereof
submitted to us for our examination. We have further assumed, without
investigation, that each document submitted to us for review and relied upon for
this opinion is accurate and complete as of the date given to the date hereof.
We have also relied upon the representations and warranties as to factual
matters contained in and made pursuant to the Underwriting Agreement.
 
     Whenever the opinion herein with respect to the existence or absence of
facts is indicated to be based on my knowledge or current conscious awareness,
it is intended to signify that during the course of my representation of the
Company or that of the attorneys acting under my direct supervision who have had
an active involvement in the transactions contemplated by the Underwriting
Agreement, no information has come to our attention which would give us actual
knowledge of the existence or absence of such facts contrary to such opinion or
statement.
   18
 
     Pursuant to the requirements of Section 3(b)(1) of the Underwriting
Agreement, this will advise you that in the opinion of the undersigned:
 
          1. The Company is a duly organized and validly existing corporation in
     good standing under the laws of the State of Michigan.
 
          2. Consumers Power Company is a duly organized and validly existing
     corporation in good standing under the laws of the State of Michigan.
 
          3. The Company's Restated Articles of Incorporation establishing the
     Class G Common Stock, no par value, as a new class of the Company's common
     stock, have been duly filed in the Office of the Michigan Department of
     Commerce, all necessary corporate and shareholder actions in connection
     therewith have been duly taken, and said Restated Articles of Incorporation
     are valid and in full force and effect in accordance with their terms on
     the date hereof.
 
          4. The Securities have been duly authorized by all necessary corporate
     action on the part of the Company and validly issued and are fully paid and
     non-assessable, and the issuance of the Securities will not be subject to
     any preemptive or similar rights.
 
          5. The shares of common stock of the Company outstanding prior to the
     issuance of the Securities have been duly authorized and are validly
     issued, fully paid and non-assessable, and the capital stock of the Company
     conforms in all material respects to the description thereof in the
     Prospectus.
 
          6. All legally required corporate proceedings in connection with the
     authorization, issuance and validity of the Securities and the sale of the
     Securities by the Company in accordance with the Underwriting Agreement
     have been taken; and no approval, authorization, consent or other order of
     any Michigan governmental regulatory body is required with respect to the
     issuance and sale of the Securities as contemplated in the Underwriting
     Agreement (other than in connection with or in compliance with the
     provisions of the Michigan securities or Blue Sky laws, as to which I
     express no opinion).
 
          7. I do not know of any legal or governmental proceedings required to
     be described in the Prospectus that are not described as required, nor of
     any contracts or documents of a character required to be described in the
     Registration Statement or Prospectus or to be filed as exhibits to the
     Registration Statement that are not described or filed as required.
 
          8. The statements made in the Prospectus under the caption
     "Description of Capital Stock" accurately summarize the provisions of the
     Company's Articles of Incorporation, as amended, and the Securities conform
     as to legal matters in all material respects to the description thereof and
     to the statements in regard thereto contained in the Registration Statement
     and the Prospectus.
 
          9. The Underwriting Agreement has been duly authorized, executed and
     delivered by the Company.
 
     The opinions expressed herein are limited to the laws of the State of
Michigan.
 
     I consent to the reliance on this opinion by Sidley & Austin and Reid &
Priest LLP in their opinions to you of even date herewith pursuant to the
Underwriting Agreement. Subject to the foregoing, this opinion is being
delivered solely for the benefit of the Underwriters and it may not be quoted,
filed with any governmental authority or other regulatory agency or otherwise
circulated or utilized for any other purpose without my prior written consent.

           Re: CMS Energy Corporation
               8,000,000 Shares of Class G Common Stock (no par value)
 
Ladies and Gentlemen:
 
     We address this opinion to you individually and as Representatives of the
Underwriters (the "Underwriters") named in Schedule II to the Underwriting
Agreement dated                , 1995 (the "Underwriting Agreement") between
you, as such Representatives, and CMS Energy Corporation, a Michigan corporation
(the "Company"), with respect to the issuance and sale of up to 8,000,000 shares
of the Company's Class G Common Stock, no par value (the "Securities").
Capitalized terms not defined herein have the meanings specified in the
Underwriting Agreement.
 
     In rendering the opinions expressed below, we have examined originals, or
copies of originals certified to our satisfaction, of such agreements,
documents, certificates and other statements of governmental officials and
corporate officers, including, without limitation, a certificate of the transfer
agent and registrar as to the execution of the Securities and the cross-receipt
with regard to the delivery thereof and the payment therefor, and such other
papers and evidence as we have deemed relevant and necessary as a basis for such
opinions. We have assumed the authenticity of all documents submitted to us as

persons and the conformity with the original documents of any copies thereof
submitted to us for our examination. We have also relied upon the
representations and warranties as to factual matters contained in and made

     Pursuant to the requirements of Section 3(b)(1) of the Underwriting
Agreement, this will advise you that in the opinion of the undersigned, as

          1. The Company is a duly organized and validly existing corporation in
     good standing under the laws of the State of Michigan.
 
          2. Consumers Power Company is a duly organized and validly existing

   20
 
          3. The Company's Restated Articles of Incorporation, establishing the
     Class G Common Stock, no par value, as a new class of the Company's common
     stock, have been duly filed in the Office of the Michigan Department of
     Commerce, all necessary corporate and shareholder actions in connection
     therewith have been duly taken, and said Restated Articles of Incorporation
     are valid and in full force and effect in accordance with their terms on
     the date hereof.
 
          4. The Securities have been duly authorized by all necessary corporate
     action on the part of the Company and are validly issued, fully paid and
     non-assessable, and the issuance of the Securities will not be subject to
     any preemptive or similar rights.
 
          5. The shares of common stock of the Company outstanding prior to the
     issuance of the Securities have been duly authorized and are validly
     issued, fully paid and non-assessable, and the capital stock of the Company
     conforms in all material respects to the description thereof in the
     Prospectus.
 
          6. All legally required corporate proceedings in connection with the
     authorization, issuance and validity of the Securities and the sale of the
     Securities by the Company in accordance with the Underwriting Agreement
     have been taken; and, except for the order of the Commission which is
     required under the Act and has been obtained, no approval, authorization,
     consent or other order of any governmental regulatory body is required with
     respect to the issuance and sale of the Securities (other than in
     connection with or in compliance with the provisions of the securities or
     Blue Sky laws of any State, as to which we have not been asked to express
     an opinion).
 
          7. We do not know of any legal or governmental proceedings required to
     be described in the Prospectus that are not described as required, nor of
     any contracts or documents of a character required to be described in the
     Registration Statement or Prospectus or to be filed as exhibits to the
     Registration Statement that are not described or filed as required.
 
          8. The statements made in the Prospectus under the caption
     "Description of Capital Stock" accurately summarize the provisions of the
     Company's Articles of Incorporation, as amended, and the Securities conform
     as to legal matters in all material respects to the description thereof and
     to the statements in regard thereto contained in the Registration Statement
     and the Prospectus.
 
          9. The Registration Statement has become effective under the Act and,
     to our knowledge, no stop order suspending the effectiveness of the
     Registration Statement has been issued and no proceedings for that purpose
     have been instituted or are pending or threatened under the Act.
 
          10. The Registration Statement, as of its effective date, and the
     Prospectus, as of the date thereof (except in each case for (i) the
     operating statistics, financial statements and schedules contained or
     incorporated by reference therein (including the notes thereto and
     auditors' reports thereon), (ii) the other financial or statistical
     information contained or incorporated by reference therein and (iii) the
     exhibits thereto, as to all of which we express no opinion), complied as to
     form in all material respects with the requirements of Form S-3 under the
     Act and the applicable rules and regulations of the Commission thereunder,
     and each document incorporated therein as originally filed pursuant to the
     Exchange Act (except for (i) the operating statistics, financial statements
     and schedules contained or incorporated by reference therein (including the
     notes thereto and the auditors' reports thereon), (ii) the other financial
     or statistical information contained or incorporated by reference therein
     and (iii) the exhibits thereto, as to which we express no opinion) complied
     as to form when so filed in all material respects with the Exchange Act and
     the applicable rules and regulations of the Commission thereunder.
 
          11. Based upon the timely filing by the Company with the Commission of
     an exemption statement pursuant to Rule 2 under the Public Utility Holding
     Company Act of 1935, as amended (the "1935 Act") which, to the best of our
     knowledge is not the subject of any notification provided for in Rule 6
     under the 1935 Act, the Company is exempt from the provisions of the 1935
     Act except for Section 9(a)(2) thereof relating to the acquisition of
     securities of other public utility companies or public utility holding
     companies.
   21
 
          12. The Underwriting Agreement has been duly authorized, executed and
     delivered by the Company.
 
     We have participated in discussions with certain officers and other
representatives of the Company, representatives of the independent public
accountants of the Company, your representatives and counsel for the
Underwriters, at which the contents of the Registration Statement and the
Prospectus and related matters were discussed. Although we are not passing upon
and do not assume any responsibility for the accuracy, completeness or fairness
of the statements contained in the Registration Statement or the Prospectus
(except to the extent stated in paragraph 8 above), we advise you that, on the
basis of the foregoing (relying as to materiality to a large extent upon
statements and other representations of officers and other representatives of
the Company), no facts have come to our attention that lead us to believe that
the Registration Statement (except for the operating statistics, financial
statements and schedules and other financial and statistical data included or
incorporated by reference therein, as to which we do not comment) on its
effective date, contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, or that the Prospectus (except for the
operating statistics, financial statements and schedules and other financial and
statistical data contained or incorporated by reference therein, as to which we
do not comment) as of its date contained, or as of the date hereof contains, any
untrue statement of a material fact or omits to state a material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading.
 
     The opinions expressed herein are limited to the laws of the States of New
York and Michigan and the Federal laws of the United States of America. Insofar
as the foregoing opinions involve the laws of the State of Michigan, we have
relied exclusively, with your consent, upon the opinion of even date of Denise
M. Sturdy, Esq., Assistant General Counsel of the Company, addressed to you
pursuant to Section 3(b)(1) of the Underwriting Agreement. We believe that you
and we are justified in relying on Ms. Sturdy's opinion for such purposes.
 
     Any opinion or statement herein which is expressed to be "to our knowledge"
or is otherwise qualified by words of like import means that the attorneys in
this Firm who have had an active involvement in the transaction contemplated by
the Underwriting Agreement have no current conscious awareness of any facts or
information contrary to such opinion or statement.
 
     We consent to the reliance on paragraph 11 of this opinion by Reid & Priest
LLP, counsel for the Underwriters, in their opinion to you of even date herewith
pursuant to the Underwriting Agreement. Subject to the foregoing, this opinion
is being delivered solely for the benefit of the Underwriters. Accordingly, it
may not be quoted, filed with any governmental authority or other regulatory
agency or otherwise circulated or utilized for any other purpose without our
prior written consent.
 
                                          Very truly yours,

pursuant to Rule 424 of the rules and regulations of the Securities and Exchange
Commission (the "Commission") under the Act, which pursuant to Form S-3

Exchange Act of 1934, as amended (the "Exchange Act"); and the Company's
Restated Articles of Incorporation as filed with the Department of Commerce of
the State of Michigan on June 6, 1995 (the "Articles"). In addition, we have
examined, and have relied as to matters of fact upon, the documents delivered to
you by the Company at the closing, including, without limitation, a certificate
of the transfer agent and registrar as to the execution of the Securities, and
the cross-receipt with regard to the delivery thereof and the payment therefor
and we have made such other and further investigations as we deemed necessary to
enable us to express the opinions hereinafter set forth. With respect to such
documents, we have assumed the genuineness of signatures on documents, the legal
capacity of all persons, the authenticity of documents submitted as originals
and the conformity to originals of documents
   23
 
submitted as copies thereof. We have not examined the certificates for the
Securities except a specimen thereof.
 
          We are of the opinion that:
 
          1. The Company is a duly organized and validly existing corporation
     under the laws of the State of Michigan.
 
          2. Consumers Power Company is a duly organized and validly existing
     corporation under the laws of the State of Michigan.
 
          3. The Securities have been duly authorized by all necessary corporate
     action on the part of the Company and validly issued and are fully paid and
     non-assessable.
 
          4. The Underwriting Agreement has been duly authorized, executed and
     delivered by the Company.
 
          5. The Registration Statement, as of its effective date, and the
     Prospectus, as of the date thereof (except in each case for (i) the
     operating statistics, financial statements and schedules contained or
     incorporated by reference therein (including the notes thereto and the
     auditors' reports thereon), (ii) the other financial and statistical
     information contained or incorporated by reference therein and (iii) the
     exhibits thereto, (as to which we do not express an opinion), complied, or
     were deemed to have complied, as to form in all material respects with the
     requirements of Form S-3 under the Act and to the applicable rules and
     regulations of the Commission thereunder.
 
          6. The statements made in the Prospectus under the caption
     "Description of Capital Stock" accurately summarize in all material
     respects the provisions of the Articles, and the Securities conform as to
     legal matters in all material respects to the description thereof contained
     therein and to the statements in regard thereto contained in the
     Registration Statement and the Prospectus.
 
     We have participated in discussions with certain officers and other
representatives of the Company, counsel for the Company, representatives of the
independent certified public accountants for the Company and representatives of
the Underwriters, at which the contents of the Registration Statement and the
Prospectus and related matters were discussed. Although we are not passing upon
and do not assume any responsibility for the accuracy, completeness or fairness
of the statements contained in the Registration Statement or the Prospectus
(except to the extent set forth in paragraph 6 above), we advise you that, on
the basis of the foregoing (relying as to materiality to a large extent upon
statements and other representations of officers and other representatives of
the Company), no facts have come to our attention which lead us to believe that
the Registration Statement (except for the operating statistics, financial
statements and schedules and other financial or statistical data included or
incorporated by reference therein, as to which we do not comment) contained, on
its effective date, any untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary to make the
statements therein not misleading, or that the Prospectus (except for the
operating statistics, financial statements and schedules and other financial or
statistical data included or incorporated by reference therein, as to which we
do not comment), as of its date contained, or as of the date hereof contains,
any untrue statement of a material fact or omitted or omits to state a material
fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.
