Utility Holding Company Act of 1935 (except Section 9 thereof) which would 
otherwise require it to register thereunder.

        (xxii) The Company has complied with, and is and will be in compliance 
with, the provisions of that certain Florida act relating to disclosure of 
doing business with Cuba, codified as Section 517.075 of the Florida statutes,

exempt therefrom.

        (xxiii) None of the Company, its subsidiaries or any of their
respective directors, officers or controlling persons, has taken, directly or
indirectly, any action resulting in a violation of Regulation M under the 1934

the Securities or the Common Stock.

        (xxiv) No "forward looking statement" (as defined in Rule 175 under the

        (b) Any certificate signed by any officer of the Company or any
subsidiary  and delivered to the U.S. Underwriters or to counsel for the U.S.

     SECTION 2.  Sale and Delivery to the U.S. Underwriters; Closing.

     (a) On the basis of the representations and warranties herein contained and
subject to the terms and conditions herein set forth, the Company agrees to
sell to each U.S. Underwriter, and each U.S. Underwriter, severally and not
jointly, agrees to purchase from the Company, at the price per security set
forth in the U.S. Pricing Agreement, the number of Initial U.S. Securities set
forth in Schedule A hereto opposite the name of such U.S.  Underwriter, plus
any additional number of Initial U.S. Securities which such Underwriter may
become obligated to purchase pursuant to the provisions of Section 10 hereof.

     (b) In addition, on the basis of the representations and warranties herein
contained and subject to the terms and conditions herein set forth, the Company
hereby grants an option to the U.S. Underwriters, severally and not jointly, to
purchase at their election up to an additional 1,050,000 shares of Common Stock
at the price per share set forth in the U.S. Pricing Agreement, less an amount
per share equal to any dividends or distributions declared by the Company and
payable on the Initial U.S. Securities but not payable on the U.S. Option
Securities.  The option hereby granted will expire automatically at the close
of business on the 30th calendar day after the date of the U.S. Pricing
Agreement and may be exercised in whole or in part from time to time only for
the purpose of covering over-allotments which may be made in connection with
the offering and distribution of the Initial U.S. Securities upon notice by the
U.S. Representatives to the Company setting forth the number of U.S. Option
Securities as to which the several U.S. Underwriters are then exercising the
option and the time and date of payment and delivery for such U.S. Option
Securities.  Any such time and date of delivery (a "Date of Delivery") shall be
determined by the U.S. Representatives but shall not be later than seven full
business days after the exercise of said option, nor in any event prior to the
Closing Time, unless otherwise agreed upon by Merrill Lynch and the Company.
If the option is exercised as to all or any portion of the U.S. Option
Securities, each of the U.S. Underwriters, acting severally and not jointly,
will purchase that proportion of the total number of U.S. Option Securities
then being purchased which the number of Initial U.S.  Securities set forth in
Schedule A opposite the name of such U.S.


                                    -15-
   16


Underwriter bears to the total number of Initial U.S. Securities, subject in 
each case to such adjustments as the U.S. Representatives in their discretion 
shall make to eliminate any sales or purchases of fractional shares.

     (c) Payment of the purchase price for, and delivery of certificates for,
the Initial Securities shall be made at the offices of LeBoeuf, Lamb, Greene &
MacRae, L.L.P, 125 West 55th Street, New York, New York  10019, or at such
other place as shall be agreed upon by the U.S. Representatives and the
Company, at 9:00 a.m. (Eastern time) on the third (fourth, if pricing of the
Securities occurs after 4:30 p.m. (Eastern time) on any given day) business day
after the date of execution of the U.S. Pricing Agreement (unless postponed in
accordance with the provisions of Section 10), or such other time not later
than ten business days after such date as shall be agreed upon by the U.S.
Representatives and the Company (such time and date of payment and delivery
being referred to herein as the "Closing Time").

        In addition, in the event that any or all of the U.S. Option Securities
are purchased by the U.S. Underwriters, payment of the purchase price for, and
delivery of certificates for, such U.S. Option Securities shall be made at the
above-mentioned offices, or at such other place as shall be agreed upon by the
U.S. Representatives and the Company, on each Date of Delivery as specified in
the notice from the U.S. Representatives to the Company.

        Payment shall be made to the Company by wire transfer of immediately
available funds to a bank account designated by the Company, against delivery
to the U.S. Representatives for the respective accounts of the U.S.
Underwriters of certificates for the U.S. Securities to be purchased by them.
It is understood that each U.S. Underwriter has authorized the U.S.
Representatives, for its account, to accept delivery of, receipt for, and make
payment of the purchase price for, the Initial U.S. Securities and the U.S.
Option Securities, if any, which it has agreed to purchase.  Merrill Lynch,
individually and not as representative of the U.S. Underwriters, may (but shall
not be obligated to) make payment of the purchase price for the Initial U.S.
Securities or the U.S. Option Securities, if any, to be purchased by any U.S.
Underwriter whose funds have not been received by the Closing Time of the
relevant of Date of Delivery,

                                    -16-

   17


as the case may be, but such payment shall not relieve such U.S. Underwriter
from its obligations hereunder.

     (d) Certificates for the Initial U.S. Securities and the U.S. Option
Securities, if any, shall be in such denominations and registered in such names
as the U.S. Representatives may request in writing at least one full business
day before the Closing Time or the relevant Date of Delivery, as the case may
be.  The certificates for the Initial U.S. Securities and the U.S. Option
Securities, if any, will be made available for examination and packaging by the
U.S. Representatives no later than 10:00 a.m. (Eastern time) on the business
day prior to the Closing Time or the relevant Date of Delivery, as the case may
be.

     (e) If settlement for the U.S. Option Securities occurs after the Closing
Time, the Company will deliver to the U.S. Underwriters on the relevant Date of
Delivery, and the obligations of the U.S. Underwriters to purchase the U.S.
Option Securities shall be conditioned upon the receipt of, supplemental
opinions, certificates and letters confirming as of such date the opinions,
certificates and letters delivered at the Closing Time pursuant to Section 5(i)
hereof.

     SECTION 3.  Covenants of the Company.  The Company covenants with each U.S.
Underwriter as follows:

     (a) Promptly following the execution of this Agreement, the Company will 
cause the Prospectuses, including as a part thereof a prospectus supplement 
relating to the Securities, to be filed with the Commission pursuant to Rule 
424(b) of the 1933 Act Regulations and will take steps as it deems necessary 
to ascertain promptly whether the form of prospectus transmitted for filing 
under Rule 424(b) was received for filing by the Commission and, in the event 
that it was not, it will promptly file such prospectus.

     (b) The Company, subject to Section 3(b), will comply with the 
requirements of Rule 430A or Rule 434 of the 1933 Act Regulations, as

amendment to the Registration Statement or the filing of any supplement or


                                    -17-
   18

amendment to the Prospectuses, (ii) of the receipt of any comments from the
Commission, (iii) of any request by the Commission for any amendment to the
Registration Statement or any amendment or supplement to the Prospectuses or
for additional information and (iv) of the issuance by the Commission of any
stop order suspending the effectiveness of the Registration Statement or of any
order preventing or suspending the use of any preliminary prospectus or
Prospectuses, or of the suspension of the qualification of the Securities for
offering or sale in any jurisdiction, or of the initiation or threatening of
any proceedings for any of such purposes.  The Company will make every
reasonable effort to prevent the issuance of any stop order and, if any stop
order is issued, to obtain the lifting thereof at the earliest possible moment.

     (c) The Company will give the U.S. Representatives notice of its intention 
to file or prepare any amendment to the Registration Statement (including any
post-effective amendment and any filing under Rule 462(b) of the 1933 Act
Regulations), any Term Sheet or any amendment, supplement or revision to either
the prospectus included in the Registration Statement at the time it became
effective or to the Prospectuses, whether pursuant to the 1933 Act, the 1934
Act or otherwise; will furnish the U.S.  Representatives with copies of any
such Rule 462(b) Registration Statement, Term Sheet, amendment, supplement or
revision a reasonable amount of time prior to such proposed filing or use, as
the case may be; and will not file any such Rule 462(b) Registration Statement,
Term Sheet, amendment, supplement or revision to which the U.S. Representatives
or counsel for the U.S. Underwriters shall object.

     (d) The Company has furnished or will deliver to the U.S. Representatives
and counsel for the U.S. Underwriters, without charge, signed copies of the
Registration Statement as originally filed and of each amendment thereto
(including exhibits filed therewith or incorporated by reference therein and
documents incorporated or deemed to be incorporated by reference therein) and
signed copies of all consents and certificates of experts, and will also
deliver to the U.S. Representatives, without charge, a conformed copy of the
Registration Statement as originally filed and of each amendment thereto
(without exhibits) for each of the U.S. Underwriters.  The copies of the
Registration Statement and each amendment thereto furnished to

                                    -18-
   19


the U.S. Underwriters will be identical to the electronically transmitted
copies thereof filed with the Commission pursuant to EDGAR, except to the
extent permitted by Regulation S-T.

     (e) The Company will deliver to each U.S. Underwriter, without charge,
as many copies of each preliminary prospectus as such U.S. Underwriter may 
reasonably request, and the Company hereby consents to the use of such copies
for purposes permitted by the 1933 Act.  The Company will furnish to each U.S.
Underwriter, without charge, during the period when the U.S. Prospectus is
required to be delivered under the 1933 Act or the 1934 Act, such number of
copies of the U.S. Prospectus (as amended or supplemented) as such U.S.
Underwriter may reasonably request.  The U.S. Prospectus and any amendments or
supplements thereto furnished to the U.S. Underwriters will be identical to the
electronically transmitted copies thereof filed with the Commission pursuant to
EDGAR, except to the extent permitted by Regulation S-T.

     (f) The Company will comply with the 1933 Act and the 1933 Act
Regulations and the 1934 Act and the 1934 Act Regulations so as to permit the
completion of the distribution of the Securities as contemplated in this
Agreement, the International Purchase Agreement and in the Prospectuses.  If at
any time when a prospectus is required by the 1933 Act or the 1934 Act to be
delivered in connection with sales of the Securities, any event shall occur or
condition shall exist as a result of which it is necessary, in the opinion of
counsel for the U.S. Underwriters or for the Company, to amend the Registration
Statement or amend or supplement any Prospectus in order that the Prospectuses
will not include an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein not misleading
in the light of the circumstances existing at the time it is delivered to a
purchaser, or if it shall be necessary, in the opinion of such counsel, at any
time to amend the Registration Statement or amend or supplement any Prospectus
in order to comply with the requirements of the 1933 Act or the 1933 Act
Regulations, the Company will promptly prepare and file with the Commission,
subject to Section 3(c), such amendment or supplement as may be necessary to
correct such statement or omission or to make the Registration Statement or the
Prospectuses comply with such requirements, and the Company will furnish to the
U.S. Underwriters, without charge, such number of


                                    -19-
   20


copies of such amendment or supplement as the U.S. Underwriters may reasonably
request.

     (g) The Company will use its best efforts, in cooperation with the U.S.
Underwriters, to qualify the Securities for offering and sale under the
applicable securities laws of such states and other jurisdictions (domestic or
foreign) as the U.S. Representatives may designate; provided, however, that the
Company shall not be obligated to file any general consent to service of
process or to qualify as a foreign corporation or as a dealer in securities in
any jurisdiction in which it is not so qualified or to subject itself to
taxation in respect of doing business in any jurisdiction in which it is not
otherwise so subject.  In each jurisdiction in which the Securities have been
so qualified, the Company will file such statements and reports as may be
required by the laws of such jurisdiction to continue such qualification in
effect for so long as may be required in connection with distribution of the
Securities.

     (h) The Company will timely file such reports pursuant to the 1934 Act as
are necessary in order to make generally available to its securityholders as 
soon as practicable an earnings statement for the purposes of, and to provide 
the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 
Act.

     (i) The Company will use the net proceeds received by it from the sale of
the Securities in the manner specified in the Prospectuses under "Use of 
Proceeds".

     (j) If, at the time that the Registration Statement became (or in the case 
of a post-effective amendment becomes) effective, any information shall have 
been omitted therefrom in reliance upon Rule 430A or Rule 434 of the 1933 Act
Regulations, then immediately following the execution of the U.S. Pricing
Agreement, the Company will prepare, and file or transmit for filing with the
Commission in accordance with such Rule 430A or Rule 434 and Rule 424(b) of the
1933 Act Regulations, copies of an amended Prospectus, or Term Sheet, or, if
required by such Rule 430A, a post-effective amendment to the Registration
Statement (including an amended Prospectus), containing all information so
omitted.


                                    -20-
   21

     (k) If the Company elects to rely upon Rule 462(b), the Company shall file 
a Rule 462(b) Registration Statement with the Commission in compliance with Rule
462(b) and pay the applicable fees in accordance with Rule 111 of the 1933 Act
Regulations by the earlier of (i) 10:00 p.m. Eastern time on the date of the
U.S. Pricing Agreement and (ii) the time confirmations are sent or given, as
specified by Rule 462(b)(2).

     (l) The Company, during the period when the Prospectuses are required to be
delivered under the 1933 Act or the 1934 Act, will file all documents required
to be filed with the Commission pursuant to the 1934 Act within the time
periods required by the 1934 Act and the 1934 Act Regulations.

     (m) The Company will use its best efforts to effect the listing of the
Securities on the New York Stock Exchange.

     (n) During a period of 90 days from the date of the Prospectuses, the 
Company will not, without the prior written consent of Merrill Lynch, directly
or indirectly, issue, pledge, sell, offer to sell, grant any option for the sale
of or otherwise transfer or dispose of, any share of Common Stock or any
securities convertible into or exchangeable or exercisable for Common Stock,
except for (a) the Securities to be sold hereunder or under the International
Purchase Agreement, (b) any shares of Common Stock issued or options to
purchase Common Stock granted pursuant to existing employee benefit plans of
the Company and its subsidiaries and (c) any shares of Common Stock issued
pursuant to dividend reinvestment and stock purchase plans of the Company.

     (o) During a period of three years from the Closing Time, to make generally
available to the U.S. Underwriters copies of all reports and other
communications (financial or other) mailed to stockholders, and to deliver to
the U.S. Underwriters promptly after they are available, copies of any reports
and financial statements furnished to or filed with the Commission or any
national securities exchange on which any class of securities of the Company is
listed; and shall furnish such additional information concerning the business
and financial condition of the Company as the U.S. Underwriters may from time
to time reasonably request (such financial statements to be on a consolidated
basis to the extent the accounts of the Company and


                                    -21-
   22


its subsidiaries are consolidated in reports furnished to its stockholders
generally or to the Commission).

     (q) None of the Company, its subsidiaries or any of their respective
directors, officers or controlling persons, will take, directly or indirectly,
any action resulting in a violation of Regulation M under the 1934 Act, or
designed to cause or result in, or that reasonably might be expected to
constitute, the stabilization or manipulation of the price of any security of
the Company to facilitate the sale or resale of the Securities.

     SECTION 4.  Payment of Expenses.  The Company will pay all expenses 
incident to the performance of its obligations under this Agreement and the 
U.S. Pricing Agreement, including, without limitation, expenses related to the
following, if incurred: (i) the preparation, delivery, printing and filing of 
the Registration Statement (including financial statements and exhibits) as
originally filed and of each amendment thereto; (ii) the printing and delivery

the certificates for the Securities to the Underwriters, including any stock or
other transfer taxes or any stamp or other duties payable upon the sale of the
Securities to the Underwriters and the transfer of the Securities between the
U.S. Underwriters and the International Managers; (iv) the fees and
disbursements of the Company's counsel, accountants and other advisors or
agents; (v) the qualification of the Securities under securities laws in
accordance with the provisions of Section 3(g), including filing fees and the
fees and disbursements of counsel for the U.S. Underwriters in connection
therewith and in connection with the preparation of the Blue Sky Survey and any
supplement thereto; (vi) the printing and delivery to the Underwriters of

registrar for the Securities, (ix) any fees payable to the Commission; and (x)

                                    -22-

of its covenants and other obligations hereunder, and to the following further
conditions:

     (a) The Registration Statement, including any Rule 462(b) Registration

at the Closing Time and any Date of Delivery, no stop order suspending the
effectiveness of the Registration Statement shall have been issued under the
1933 Act or proceedings therefor initiated or threatened by the Commission, and
any request on the part of the Commission for additional information shall have
been complied with to the satisfaction of counsel to the U.S. Underwriters.  A

           (iii) The Company is duly qualified as a foreign corporation to 
      transact business and is in good standing in each jurisdiction in which 
      such qualification is required, whether by reason of the ownership or 
      leasing of property or the conduct of business, except where the failure
      so to qualify or to be in good standing would not result in a Material 
      Adverse Effect.

           (iv) The authorized, issued and outstanding capital stock of the 
      Company is as set forth in the Prospectuses (except for subsequent 
      issuances, if any, pursuant to the U.S. Purchase Agreement and the 
      International Purchase Agreement or pursuant to employee benefit plan or

      respectively, against payment of the consideration set forth in the U.S.
      Pricing Agreement and the International Pricing Agreement, will be
      validly issued and fully paid and non-assessable.  The form of
      certificate used to evidence the Securities is in due and proper form and
      complies with the applicable statutory requirements, with any applicable
      requirements of the charter or by-laws of the Company, and with the
      requirements of the New York Stock Exchange.

           (vi) The issuance of the Securities is not subject to preemptive or
      other similar rights arising by law or, to the best of such counsel's
      knowledge, otherwise.

      all of the issued and outstanding capital stock of each such subsidiary
      of the Company has been duly authorized and validly issued, is fully paid
      and non-assessable and all such shares are owned by the Company, directly
      or through its subsidiaries, free and clear of any security interest,
      mortgage, pledge, lien, encumbrance, claim or equity.  None of the
      outstanding shares of capital stock of any subsidiary of the Company was
      issued in


                                    -25-

   26

      violation of preemptive or other similar rights of any securityholder of

      and, to the best knowledge of such counsel, no stop order suspending the
      effectiveness of the Registration Statement or any Rule 462(b)
      Registration Statement has been issued under the 1933 Act and no
      proceedings therefor have been initiated or threatened by the Commission.

           (xi) The Registration Statement, including any Rule 462(b) 
      Registration Statement, the Rule 430A Information and the Rule 434
      Information, as applicable, the Prospectuses, excluding the documents

      the Registration Statement and Prospectuses, excluding the documents
      incorporated by reference therein, as of their respective effective or
      issue dates (other than the financial statements and supporting schedules
      included therein, as to which such counsel need express no opinion),
      complied as to form in all material respects with the requirements of the
      1933 Act and the 1933 Act Regulations.

           (xii) The documents incorporated by reference in the Prospectuses

      Agreement, the U.S. Pricing Agreement, the International Purchase
      Agreement and the International Pricing Agreement and the consummation of
      the transactions contemplated herein and therein and in the Registration
      Statement and Prospectus and compliance by the Company with its
      obligations hereunder and thereunder do not and will not, whether with or
      without the giving of notice or passage of time or both, conflict with or

      of its subsidiaries is subject, except for such conflicts, breaches,
      defaults, liens, charges or encumbrances that would not result in a
      Material Adverse Effect, nor will such action result in any violation of

      thereof, or any applicable law, statute, rule, regulation, judgment,
      order, writ or decree of any government, governmental instrumentality or

      of its subsidiaries or any of their respective properties, assets or

      be expected to result in a Material Adverse Effect, or which might

      properties or operations thereof of the consummation of the transactions
      contemplated in this Agreement, the U.S. Pricing Agreement, the
      International Purchase Agreement and the International

      indentures, mortgages, loan or credit agreements, notes, leases or other

      1933 Act Regulations, which have been obtained, or as may be required
      under the securities or blue sky laws of the various states, as to which
      such counsel need express no opinion) is necessary or required in

      issuance and sale of the Securities or the performance by the Company of
      its obligations in this Agreement, the U.S. Pricing Agreement, the

           (xx) The Company and its subsidiaries possess all licenses,

      them and for the operation of the business carried on by each of them as
      described in the Registration Statement and the Prospectuses with such
      exceptions as are not material and do not materially interfere with the
      conduct of the business of the Company and its subsidiaries, considered
      as one enterprise; all such licenses, franchises, permits, certificates,
      authorizations, approvals, consents and orders are in full force and
      effect and contain no unduly burdensome provisions that would interfere
      with the conduct of the business of the Company and its subsidiaries,
      considered as one enterprise and, except as otherwise set forth in the
      Registration Statement or the Prospectus, there are no legal or
      governmental proceedings pending or threatened that would result in a
      material modification, suspension or revocation thereof.

           (xxi) The Company is not an "investment company" or an entity under

   30
           Moreover, such counsel shall confirm that nothing has come to such
      counsel's attention that would lead such counsel to believe that the
      Registration Statement, including any Rule 430A Information and Rule 434
      Information (if applicable)(except for financial statements and the notes
      thereto, the financial schedules and any other financial data included or
      incorporated by reference therein, as to which counsel need express no
      opinion), at the time such Registration Statement became effective or at
      the date of the U.S. Pricing Agreement, 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 not misleading or
      that the Prospectuses or any amendment or supplement thereto (except for
      financial statements and the notes thereto, the financial schedules, and
      any other financial data included or incorporated by reference therein,
      as to which counsel need express no opinion), at the time the
      Prospectuses were issued, at the time of any such amended or supplemented
      Prospectuses were issued or at the Closing Time, included or includes an
      untrue statement of a material fact or omitted or omits to state a
      material fact necessary in order to make the statements therein, in the
      light of the circumstances under which they were made, not misleading.

Michigan law upon the opinion of Daniel L. Schiffer, Esq., counsel for the
Company, which shall be delivered in accordance with Section 5(b)(1) hereof.

     (c) At the Closing Time, the U.S. Representatives shall have received a
certificate of the President or a Vice-President of the Company and of the

and substance satisfactory to the U.S. Representatives, together with signed or
reproduced copies of such letter for each of the other U.S. Underwriters, to
the effect set forth below and as to such other matters as the U.S.
Representatives may reasonably request, that:

           (i) They are independent certified public accountants with respect
      to the Company and its subsidiaries within the meaning of the 1933 Act
      and the 1933 Act Regulations;

      respects with the applicable accounting requirements of the 1933 Act and
      the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations;

           (iii) On the basis of limited procedures, not constituting an audit

      of Certified Public Accountants of the unaudited condensed consolidated
      financial statements included in the Company's Quarterly Reports on Form
      10-Q incorporated by reference in the Registration Statement and the
      Prospectuses as amended or supplemented for the periods specified in such

      subsidiaries, a reading of the minutes of the Company and its
      subsidiaries since the audited consolidated financial statements set
      forth in the Company's Annual Report on Form 10-K for the most recent
      year, inquiries of officials of the Company and its subsidiaries
      responsible for financial and accounting matters and such other inquiries
      and procedures as may be specified in such letter, nothing came to their
      attention that caused them to believe that:

                 (A) the unaudited condensed consolidated financial statements
            set forth in the Company's Quarterly Reports on Form 10-Q
            incorporated by reference in the Registration Statement and the

            of the 1934 Act and the 1934 Act Regulations as they apply to Form
            10-Q or any material modifications should be made for them to be in
            conformity with generally accepted accounting principles applied on
            a basis substantially consistent with that of the audited
            consolidated financial statements set forth in the Company's Annual
            Report on Form 10-K for the most recent year ended incorporated by
            reference in the Registration Statement and the Prospectuses as

            consolidated financial statements from which such data and items
            were derived;

                 (C)  any unaudited pro forma consolidated condensed financial
            statements or any unaudited pro forma consolidating financial
            statements included or incorporated by reference in the
            Prospectuses as amended or supplemented do not comply as to form in
            all material respects with the applicable accounting requirements

      any governmental agency or body, commenced or threatened, or any claim 
      whatsoever based upon any such untrue statement or omission, or any such
      alleged untrue statement or omission, to the extent that any such 
      expense is not paid under (i) or (ii) above;

provided, however, that this foregoing indemnity agreement shall not apply to
any loss, liability, claim, damage or expense to the extent arising out of any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon and in conformity with written information furnished to the
Company by any U.S. Underwriter through Merrill Lynch expressly for use in the
Registration Statement (or any amendment thereto), including the Rule 430A
Information and the Rule 434 Information, if applicable, or any preliminary
prospectus or the U.S. Prospectus (or any amendment or supplement thereto);
provided, further, that such indemnity with respect to the preliminary
prospectus shall not inure to the benefit of the U.S. Underwriters (or any
person controlling such U.S. Underwriters) from whom the person asserting any
such loss, liability, claim, damage or expense purchased any of the Securities
which are the subject thereof if such person did not receive a copy of the U.S.
Prospectus (or the U.S. Prospectus as amended or supplemented) (in each case
exclusive of the documents from which information is incorporated by reference)
at or prior to the written confirmation of the sale of such U.S. Securities to
such person in any case where the Company complied with its obligations under
Sections 3(c) and 3(g) hereof and any such untrue statement or omission or
alleged untrue statement or omission of a material fact contained in such
preliminary prospectus (or any amendment or supplement thereto) was corrected
in the U.S. Prospectus (or the U.S. Prospectus as amended or supplemented).

     (b) Each U.S. Underwriter severally agrees to indemnify and hold harmless
the Company, its directors, each of its officers who signed the Registration
Statement and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all
loss,


                                    -38-
   39


liability, claim, damage and expense described in the indemnity contained 
in subsection (a) of this Section, as incurred, but only with respect to 
untrue statements or omissions, or alleged untrue statements or omissions,
made in the Registration Statement (or any amendment thereto), including the
Rule 430A Information and the Rule 434 Information, if applicable, or any
preliminary prospectus or the U.S. Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Company by such U.S. Underwriter through Merrill Lynch expressly for use
in the Registration Statement (or any amendment thereto) or such preliminary
prospectus or the U.S. Prospectus (or any amendment or supplement thereto).

     (c) Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action commenced against it in
respect of which indemnity may be sought hereunder, but failure to so notify an
indemnifying party shall not relieve such indemnifying party from any liability
hereunder to the extent it is not materially prejudiced as a result thereof and
in any event shall not relieve it from any liability which it may have
otherwise than on account of this indemnity agreement.  In the case of parties
indemnified pursuant to Section 6(a) above, counsel to the indemnified parties
shall be selected by Merrill Lynch, and, in the case of parties indemnified
pursuant to Section 6(b) above, counsel to the indemnified parties shall be
selected by the Company.  An indemnifying party may participate at its own
expense in the defense of any such action; provided, however, that counsel to
the indemnifying party shall not (except with the consent of the indemnified
party) also be counsel to the indemnified party.  In no event shall the
indemnifying parties be liable for fees and expenses of more than one counsel
(in addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar
or related actions in the same jurisdiction arising out of the same general
allegations or circumstances.  No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 6 or Section 7



                                    -39-
   40


hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act by or on behalf of any indemnified party.

     (d) If at any time an indemnified party shall have requested an 
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 6(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement
at least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.

     SECTION 7.  Contribution. If the indemnification provided for in Section 6
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the U.S. Underwriters on the other hand from the offering of the U.S.
Securities pursuant to this Agreement or (ii) if the allocation provided by
clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company on the one hand and the U.S.
Underwriters on the other hand in connection with the statements or omissions
which resulted in such losses, liabilities, claims, damages or expenses, as
well as any other relevant equitable considerations.

     The relative benefits received by the Company on the one hand and the U.S.
Underwriters on the other hand in connection


                                    -40-
   41


with the offering of the U.S. Securities pursuant to this Agreement shall be
deemed to be in the same respective proportions as the total net proceeds from
the offering of such U.S. Securities pursuant to this Agreement (before
deducting expenses) received by the Company and the total underwriting discount
received by the U.S. Underwriters, in each case as set forth on the cover of
the U.S. Prospectus, or, if Rule 434 is used, the corresponding location on the
Term Sheet, bear to the aggregate initial public offering price of such U.S.
Securities as set forth on such cover.

     The relative fault of the Company on the one hand and the U.S.
Underwriters on the other hand 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 or by the U.S. Underwriters and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

     The Company and the U.S. Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro
rata allocation (even if the U.S. Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 7.  The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 7 shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged
untrue statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 7, no U.S. Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the U.S. Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages which
such U.S. Underwriter has otherwise been required to pay by


                                    -41-
   42


reason of any 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 1933 Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 7, each person, if any, who controls a U.S.
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such U.S.
Underwriter, and each director of the Company, each officer of the Company who
signed the Registration Statement, and each person, if any, who controls the
Company within the meaning of Section 15 of the 1933 Act or Section 20 of the
1934 Act shall have the same rights to contribution as the Company.  The U.S.
Underwriters' respective obligations to contribute pursuant to this Section 7
are several in proportion to the number of Initial U.S. Securities set forth
opposite their respective names in Schedule A to this Agreement, and not joint.

     SECTION 8.  Representations, Warranties and Agreements to Survive Delivery.
All representations, warranties and agreements contained in this Agreement and
the U.S. Pricing Agreement, or contained in certificates of officers of the
Company or any of its subsidiaries submitted pursuant hereto, shall remain
operative and in full force and effect, regardless of any investigation made by
or on behalf of any U.S. Underwriter or controlling person, or by or on behalf
of the Company, and shall survive delivery of and payment for the Securities to
the U.S. Underwriters.



     SECTION 9.  Termination of Agreement.

     (a) The U.S. Representatives may terminate this Agreement, by notice to the
Company at any time at or prior to the Closing Time, if (i) there has been,
since the date of this Agreement or since the respective dates as of which
information is given in the U.S. Prospectus, any material adverse change or any


                                    -42-
   43
development which could reasonably be expected to result in a prospective 
material adverse change, financial or otherwise, or in the earnings, business 
affairs or business prospects of the Company and its subsidiaries considered as 
one enterprise, whether or not arising in the ordinary course of business, or 
(ii) there has occurred any material adverse change in the financial markets in 
the United States or any outbreak of hostilities or escalation of hostilities or
other calamity or crisis, or any change or development involving a prospective
change in national or international political, financial or economic conditions
the effect of which is such as to make it, in the judgment of the U.S.
Representatives, impracticable to market the Securities or to enforce contracts
for the sale of the Securities, or (iii) if trading in the Common Stock or any
other security of the Company has been suspended or limited by the Commission,
National Association of Securities Dealers, Inc. or the New York Stock
Exchange, or if trading generally on either the American Stock Exchange, the
New York Stock Exchange or in the over-the-counter market has been suspended or
limited, or minimum or maximum prices for trading have been fixed, or maximum
ranges for prices for securities have been required, by either of said
exchanges or by such system or by order of the Commission, NASD or any other
governmental authority, or (iv) if a banking moratorium has been declared by
either Federal, New York or Michigan authorities.

     (b) If this Agreement and the U.S. Pricing Agreement are terminated 
pursuant to this Section 9, such termination shall be without liability of any
party to any other party except as provided in Section 4, and provided, 
further, that Sections 1, 6, 7 and 8 shall survive such termination and remain
in full force and effect.

     SECTION 10.  Default by One or More of the U.S. Underwriters.  If one
or  more of the U.S. Underwriters shall fail at the Closing Time or a Date of
Delivery to purchase the Securities which it or they are obligated to purchase
under this Agreement and the U.S. Pricing Agreement (the "Defaulted
Securities"), the U.S. Representatives shall have the right, within 24 hours
thereafter, to make arrangements for one or more of the non-defaulting U.S.
Underwriters, or any other underwriters, to purchase all, but not less than
all, of the Defaulted Securities in such amounts as may be agreed upon and


                                    -43-
   44


upon the terms herein set forth; if, however, the U.S. Representatives shall
not have completed such arrangements within such 24-hour period, then:

        (a) if the number of Defaulted Securities does not exceed 10% of the 
number of U.S. Securities to be purchased on such date, each of the 
non-defaulting U.S. Underwriters shall be obligated, severally and not jointly, 
to purchase the full amount thereof in the proportions that their respective 
underwriting obligations hereunder bear to the underwriting obligations of all
non-defaulting U.S. Underwriters, or

        (b) if the number of Defaulted Securities exceeds 10% of the number of
U.S. Securities to be purchased on such date, this Agreement, or with respect
to any Date of Delivery which occurs after the Closing Time, the obligations of
the U.S. Underwriters to purchase and of the Company to sell the Option
Securities to be purchase and sold on such Date of Delivery shall terminate
without liability on the part of any non-defaulting U.S. Underwriter.

        No action taken pursuant to this Section 10 shall relieve any
defaulting U.S. Underwriter from liability in respect of its default.

        In the event of any such default which does not result in a termination
of this Agreement or, in the case of a Date of Delivery which is after the
Closing Time, which does not result in a termination of the obligation of the
U.S. Underwriters to purchase and the Company to sell the relevant U.S. Option
Securities, as the case may be, either the U.S. Representatives or the Company
shall have the right to postpone the Closing Time or the relevant Date of
Delivery, as the case may be, for a period not exceeding seven days in order to
effect any required changes in the Registration Statement or the Prospectuses
or in any other documents or arrangements.  As used herein, the term "U.S.
Underwriter" includes any person substituted for an U.S. Underwriter under this
Section 10.

     SECTION 11.  Notices.  All notices and other communications hereunder shall
be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication.  Notices to the U.S.
Underwriters shall be



                                    -44-
   45


directed to the U.S. Representatives at North Tower, World Financial Center, New
York, New York 10281-1202, attention of Anthony V. Leness, Managing Director,

the Company shall be directed to it at MCN Energy Group Inc., 500 Griswold
Street, Detroit, Michigan 48226, attention of Daniel L. Schiffer, Esq., Senior
Vice President, General Counsel and Secretary.

     SECTION 12.  Parties.  This Agreement and the U.S. Pricing Agreement shall
each inure to the benefit of and be binding upon the Company and the U.S.
Underwriters and their respective successors.  Nothing expressed or mentioned
in this Agreement or the U.S. Pricing Agreement is intended or shall be
construed to give any person, firm or corporation, other than the U.S.
Underwriters and the Company and their respective successors and the
controlling persons and officers and directors referred to in Sections 6 and 7
and their heirs and legal representatives, any legal or equitable right, remedy
or claim under or in respect of this Agreement or the U.S. Pricing Agreement or
any provision herein or therein contained.  This Agreement and the U.S. Pricing
Agreement and all conditions and provisions hereof and thereof are intended to
be for the sole and exclusive benefit of the parties hereto and thereto and
their respective successors and legal representatives, and said controlling
persons and officers and directors and their heirs and legal representatives,
and for the benefit of no other person, firm or corporation.  No purchaser of
Securities from any U.S. Underwriter shall be deemed to be a successor by
reason merely of such purchase.

     SECTION 13.  GOVERNING LAW AND TIME.  THIS AGREEMENT AND THE U.S. PRICING
AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID
STATE.  SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME UNLESS OTHERWISE
INDICATED.

     SECTION 14.  Effect of Headings.  The Article and Section headings herein
are for convenience only and shall not affect the construction hereof.

agreement, please sign and return to the Company a counterpart hereof,
whereupon this instrument, along with all counterparts, shall become a binding
agreement between the U.S. Underwriters and the Company in accordance with its
terms.

Ladies and Gentlemen:

        Reference is made to the U.S. Purchase Agreement, dated June 24, 1997
(the "U.S. Purchase Agreement"), relating to the purchase by the several U.S.
Underwriters named in Schedule A thereto for whom Merrill Lynch & Co., Merrill
Lynch, Pierce, Fenner & Smith Incorporated, Donaldson, Lufkin & Jenrette
Securities Corporation, A.G. Edwards & Sons, Inc., PaineWebber Incorporated,
Salomon Brothers Inc and Smith Barney Inc. are acting as representatives (the
"U.S. Representatives"), of the shares of common stock, par value $.01 per
share, of MCN Energy Group Inc. (the "Company").  Capitalized terms used which
are not

   51


defined herein shall have the meanings assigned to such terms in the U.S. 
Purchase Agreement.

        Pursuant to Section 2 of the U.S. Purchase Agreement, the Company
agrees with each U.S. Underwriter as follows:

        1.  The initial public offering price per share for the Securities,
    determined as provided in said Section 2, shall be $29.125.

        2.  The purchase price per share for the U.S. Securities to be paid by
    the several U.S. Underwriters shall be $28.295, being an amount equal
    to the initial public offering price set forth above less $.83 per share;
    provided that the purchase price per share for any U.S. Option Securities
    purchased upon the exercise of the over-allotment option described in
    Section 2(b) of the U.S. Purchase Agreement shall be reduced by an amount
    per share equal to any dividends or distributions declared by the Company
    and payable on the Initial U.S. Securities but not payable on the U.S.
    Option Securities.


                                     -2-

        If the foregoing is in accordance with your understanding of our
agreement, please sign and return to the Company a counterpart hereof,
whereupon this instrument, along with all counterparts, will become a binding
agreement between the U.S. Underwriters and the Company in accordance with its
terms.

                                        Very truly yours,
