Dear Sirs:

  MCN Corporation, a Michigan corporation (the "Company") and the several
Underwriters named in Schedule A hereto (collectively, the "Underwriters",
which term shall also include any underwriter substituted as hereinafter
provided in Section 10), for whom Merrill Lynch & Co., Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("Merrill Lynch"), Smith Barney Inc., Donaldson,
Lufkin & Jenrette Securities Corporation, Dean Witter Reynolds Inc. and Roney &
Co. are acting as the representatives (in such capacity, such firms shall
hereinafter be referred to as the "Representatives") propose, subject to the
terms and conditions stated herein, to enter into the Purchase Contracts
referred to in the Purchase Contract Agreement dated as of April 22, 1996 (the
"Purchase Contract Agreement") between the Company and The First National Bank
of Chicago, as Purchase Contract Agent (the "Purchase Contract Agent"),
relating to an aggregate of 5,100,000 Preferred Redeemable Increased Dividend
Equity
   2

Securities, 8 3/4% PRIDES, Stated Amount $23.00 per Security (the "PRIDES").
In connection therewith, the Underwriters propose, subject to the terms and
conditions stated herein, to purchase at the direction of the Company, the
underlying Treasury Notes of the United States Government bearing interest at
the rate of 6 1/2% per annum and maturing on April 30, 1999 (the "Treasury
Notes"), having an aggregate principal amount of $117,300,000. The Treasury
Notes will be pledged with Chemical Bank, as collateral agent for the Company
(the "Collateral Agent"), to secure the holders' obligation to purchase common
stock, $.01 par value, of the Company (the "Common Stock") under the Purchase
Contracts.  The Company proposes to grant to the Underwriters an option to
enter into Purchase Contracts underlying up to 765,000 additional PRIDES (the
"Option Securities") and, in the event any such additional Purchase Contracts
are entered into, the Underwriters propose to purchase, at the direction of the
Company, the additional Treasury Notes underlying such Option Securities, which
would also be pledged to the Collateral Agent.  The aforesaid 5,100,000 PRIDES
(the "Initial Securities") and all or any part of the Option Securities subject
to the over-allotment option described in Section 2(b) hereof are collectively
referred to herein as the "Securities".  Capitalized terms used herein without
definition shall be used as defined in the Purchase Contract Agreement.

  Prior to the purchase and public offering of the Securities by the
Underwriters, the Company and the Representatives, acting on behalf of the
several Underwriters, shall enter into an agreement substantially in the form
of Exhibit A hereto (the "Pricing Agreement").  The Pricing Agreement may take
the form of an exchange of any standard form of written telecommunication
between the Company and the Representatives and shall specify such applicable
information as is indicated in Exhibit A hereto.  The offering of the
Securities will be governed by this Agreement, as supplemented by the Pricing
Agreement.  From and after the date of the execution and delivery of the
Pricing Agreement, this Agreement shall be deemed to incorporate the Pricing
Agreement.

  The Company, and MCN Financing I and MCN Financing II (collectively, the "MCN
Trusts") have filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-01521) and
pre-effective amendment nos. 1 and 2 thereto covering the registration of
securities of the Company and the MCN Trusts, including the Securities and the
Purchase Contracts included in and shares of Common Stock underlying the
Securities, under the Securities Act of 1933, as amended (the "1933 Act"),
including the related preliminary prospectus or prospectuses, and the offering
thereof from time to time in accordance with Rule 415 of the rules and
regulations of the Commission under the 1933 Act (the "1933 Act Regulations")
and the Company has filed such post-effective amendments thereto as may be
required prior to the execution of the Pricing

                                     -2-

Agreement.  Such registration statement, as so amended, has been declared
effective by the Commission.  Such registration statement, as so amended,
including the exhibits and schedules thereto, if any, and the information, if

Regulations (the "Rule 430A Information") or Rule 434(d) of the 1933 Act
Regulations (the "Rule 434 Information"), is referred to herein as the
"Registration Statement"; and the final prospectus and the prospectus
supplement relating to the offering of the Securities, in the form first
furnished to the Underwriters by the Company for use in connection with the
offering of the Securities, are collectively referred to herein as the
"Prospectus"; provided, however, that all references to the "Registration
Statement" and the "Prospectus" shall be deemed to include all documents
incorporated therein by reference pursuant to the Securities Exchange Act of
1934, as amended (the "1934 Act"), prior to the execution of the applicable
Pricing Agreement; provided, further, that if the Company files a registration
statement with the Commission pursuant to Section 462(b) of the 1933 Act
Regulations (the "Rule 462(b) Registration Statement"), then after such filing,
all references to "Registration Statement" shall be deemed to include the Rule
462(b) Registration Statement; and provided, further, that if the Company
elects to rely upon Rule 434 of the 1933 Act Regulations, then all references

the case may be, in the form first furnished to the Underwriters by the Company
in reliance upon Rule 434 of the 1933 Act Regulations, and all references in
this Purchase Agreement to the date of the Prospectus shall mean the date of

Information or other information to be included upon pricing in a form of
prospectus filed with the Commission pursuant to Rule 424(b) of the 1933 Act
Regulations, that was used after such effectiveness and prior to the execution
and delivery of the applicable Pricing Agreement.  For purposes of this
Agreement, all references to the Registration Statement, any preliminary

offering of the Securities as soon as the Representatives deem advisable after
the Pricing Agreement has been executed and delivered.

  SECTION I.  Representations and Warranties.

   A.  The Company represents and warrants to each Underwriter as of the date

                 (i)       No stop order suspending the effectiveness of the

been initiated or, to the knowledge of the Company, threatened by the
Commission.

                 (ii)       The Company and the MCN Trusts meet the requirements
for the use of Form S-3 under the 1933 Act.  Each of the Registration Statement
and any Rule 462(b) Registration Statement has become effective under the 1933
Act, and at the time of effectiveness and at the Representation Date, the
Registration Statement and any Rule 462(b) Registration Statement and the
Prospectus conformed and will conform in all material respects to the
requirements of the 1933 Act and the 1933 Act Regulations and did not and will
not contain an untrue statement of a material fact and did not and will not
omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading; and the Prospectus, at the time the
Registration Statement became effective (unless the term "Prospectus" refers to
a prospectus which has been provided to the Underwriters by the Company for use
in connection with the offering of the Securities which differs from the
Prospectus on file at the Commission at the time the Registration Statement
became effective, in which case at the time it is first provided to the
Underwriters for such use) and at the Representation Date and at the Closing
Time referred to in Section 2, did not and 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, in the light of the circumstances under which they were
made, not misleading; provided, however, that the representations and
warranties in this subsection shall not apply to statements contained in or
omitted from the Registration Statement or the Prospectus in reliance upon, and
in conformity with, information furnished to the Company in writing by any

                                     -4-
   5

Underwriter through Merrill Lynch expressly for use in the Registration
Statement or the Prospectus.

                 (ii)       The documents incorporated or deemed to be
incorporated by reference in the Registration Statement or the Prospectus, at
the time they were or hereafter are filed or last amended, as the case may be,
with the Commission, complied and will comply in all material respects with the
requirements of the 1934 Act, and the rules and regulations of Commission
thereunder (the "1934 Act Regulations"), and at the time of filing or as of the
time of any subsequent amendment, did not contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were or are made, not misleading; and any additional documents
deemed to be incorporated by reference in the Registration Statement or the
Prospectus will, if and when such documents are filed with the Commission, or
when amended, as appropriate, comply in all material respects to the
requirements of the 1934 Act and the 1934 Act Regulations and will not contain
an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading; provided, however, that this representation and warranty shall not
apply to any statements or omissions made in reliance upon and in conformity
with information furnished in writing to the Company by an Underwriter through
Merrill Lynch expressly for use in the Registration Statement or the
Prospectus.

                 (iv)       The accountants who certified the financial
statements and supporting schedules included or incorporated by reference in
the Registration Statement are independent public accountants as required by
the 1933 Act and the 1933 Act Regulations.

                 (v)       The financial statements included or incorporated by
reference in the Registration Statement and the Prospectus, together with the
related schedules and notes, present fairly the financial position of the
Company and its consolidated subsidiaries as at the dates indicated and the
results of their operations for the periods specified.  Except as otherwise
stated in the Registration Statement, said financial statements have been
prepared in conformity with generally accepted accounting principles applied on
a consistent basis.  The supporting schedules included or incorporated by
reference in the Registration Statement present fairly the information required
to be stated therein.  The ratio of earnings to fixed charges  included in the
Prospectus has been calculated in compliance with Item 503(d) of Regulation S-K
of the Commission.  The selected financial information and the summary
financial data included in the Prospectus present fairly the information shown
therein and have been compiled on a basis consistent with that of the audited
financial statements included in the Registration Statement.

         SECTION II.  Sale and Delivery to 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
and each Underwriter, severally and not jointly, agree to enter into the
Purchase Contracts underlying the number of Initial Securities set forth in
Schedule A hereto opposite the name of such Underwriter, plus any additional
Purchase Contracts underlying the number of Initial Securities which such
Underwriter may become obligated to enter into pursuant to the provisions of
Section 10 hereof.

                (1)       If the Company has elected not to rely upon Rule 430A

Purchase Contracts at the price per share set forth in the Pricing Agreement.
The option hereby granted will expire automatically at the close of business on
the 30th calendar day after (i) the later of the date the Registration Statement
and any Rule 462(b) Registration Statement becomes effective, if the Company
has elected not to


                                    -11-
   12

rely upon Rule 430A under the 1933 Act Regulations, or (ii) the Representation
Date, if the Company has elected to rely upon Rule 430A under the 1933 Act
Regulations, 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 Securities upon notice by the
Underwriters to the Company setting forth the aggregate number of additional
Purchase Contracts to be entered into and the time and date of delivery for the
related Option Securities.  Any such time and date of delivery (a "Date of
Delivery") shall be determined by the Underwriters but shall not be later than
seven full business days after the exercise of such option, nor in any event
before the Closing Time, as hereinafter defined, unless otherwise agreed upon
by the Underwriters and the Company.  If the option is exercised as to all or
any portion of the Option Securities, each of the Underwriters, acting
severally and not jointly, will enter into that proportion of the total number
of additional Purchase Contracts as to which such election has been exercised
which the number of Initial Securities set forth in Schedule A opposite the
name of such Underwriter bears to the total number of Initial Securities
(subject in each case to such adjustments as the Underwriters in their
discretion shall make to eliminate any fractional Purchase Contracts).

         (c)     The Underwriters agree to purchase, at the direction of the
Company, the Treasury Notes underlying the Securities with respect to which the
Company and the Underwriters have entered into the Purchase Contracts.  The
Treasury Notes will be pledged with the Collateral Agent to secure the holders'
obligations to purchase Common Stock under the Purchase Contracts.  Such pledge
shall be effected by the transfer to the Collateral Agent by Federal Reserve
Bank-Wire of the Treasury Notes to be pledged at the Closing Time and
appropriate Date of Delivery, if any, in accordance with the Pledge Agreement.

         (d)     Delivery of certificates for the Initial Securities with
respect to which each Underwriter enters into Purchase Contracts hereunder
shall be made at the offices of the Representatives in New York for the account
of the Underwriters, against the delivery to the Collateral Agent of the
Treasury Notes relating to such Initial Securities by such Underwriters or on
their behalf.  At such same time, the Company will pay to the Representatives,
Underwriters' commissions in the amount of $.69 per Security plus $1.001 per
Security, resulting in a net payment of $1.691 per Security (the
"Commissions"), in same-day funds 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 Underwriters and the Company, at 10:00
a.m. (New York time) on the third business day after the date the Registration
Statement becomes effective (or, if the Company has elected to rely upon Rule
430A, the third full business day after execution of the Pricing Agreement (or,
if pricing of the Securities occurs after 4:30 p.m.  Eastern time, on

                                    -12-
   13

the fourth full business day thereafter)), or such other time not later than
ten business days after such date as shall be agreed upon by the Underwriters
and the Company (such time and date of payment and delivery being herein called
the "Closing Time").  In addition, if the Underwriters enter any or all of the
Purchase Contracts underlying the Option Securities, payment of the Commissions
and delivery of certificates for such Option Securities shall be made at the
offices of LeBoeuf, Lamb, Greene & MacRae, L.L.P. set forth above, or at such
other place as shall be agreed upon by the Underwriters and the Company, on
each Date of Delivery as specified in the relevant notice from the Underwriters
to the Company.  Certificates for the Initial Securities and the Option
Securities shall be in such denominations and registered in such names as the
Underwriters may request in writing at least two full business days before the
Closing Time or any Date of Delivery, as the case may be. The certificates for
the Initial Securities and the Option Securities, if any, will be made
available for examination and packaging by the Underwriters no later than 10:00
a.m. (New York City time) on the last business day prior to the Closing Time or
the Date of Delivery, as the case may be.

         SECTION 3.  Covenants of the Company.  The Company agrees with each
Underwriter as follows:

        (a)      Promptly following the execution of this Agreement, the
Company will cause the Prospectus, including as a part thereof a prospectus
supplement relating to the Securities to be filed with the Commission pursuant
to Rule 424 of the 1933 Act Regulations and the Company will promptly advise
the Underwriters when such filing has been made.  Prior to the filing, the
Company will cooperate with the Underwriters in the preparation of such
prospectus supplement to assure that the Underwriters have no reasonable
objection to the form or content thereof when filed or mailed.

        (b)      The Company will comply with the requirements of Rule 430A of
the 1933 Act Regulations and/or Rule 434 of the 1933 Act Regulations if and as
applicable, and will notify the Underwriters immediately, and confirm the
notice in writing, (i) of the effectiveness of any post-effective amendment to
the Registration Statement or the filing of any supplement or amendment to the
Prospectus, (ii) of any request by the Commission for any amendment to the
Registration Statement or any amendment or supplement to the Prospectus or for
additional information, (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement or the
initiation of any proceedings for that purpose and (iv) of the issuance by any
state securities commission or other regulatory authority of any order
suspending the qualification or the exemption from qualification of the
Securities or the Shares under state securities or Blue Sky laws or the
initiation or threatening of any proceeding for such purpose.  The Company will

                                    -13-
   14

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 Underwriters 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 Prospectus (including any revised prospectus or Term Sheet
and preliminary prospectus which the Company proposes for use by the
Underwriters in connection with the offering of the Securities which differs
from the prospectus on file at the Commission at the time the Registration
Statement became effective, whether or not such revised prospectus or Term
Sheet and preliminary prospectus is required to be filed pursuant to Rule
424(b) of the 1933 Act Regulations), whether pursuant to the 1933 Act, the 1934
Act or otherwise; will furnish the Underwriters 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 Underwriters or counsel for the
Underwriters shall object.

        (d)      The Company will deliver to the Underwriters as many 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) as the Underwriters may reasonably request and will also deliver to
the Underwriters, without charge, a conformed copy of the Registration
Statement as originally filed and of each amendment thereto (without exhibits).
If applicable, the copies of the Registration Statement and each amendment
thereto furnished to the 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 Underwriter, without charge,
as many copies of each preliminary prospectus as such 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
Underwriter, from time to time during the period when the Prospectus is
required to be delivered under the 1933 Act or the 1934 Act, such number of
copies of the Prospectus (as amended or supplemented) as such Underwriter may
reasonably request.  If applicable, the Prospectus and any amendments or
supplements thereto furnished to the Underwriters will be identical to the
electronically

                                    -14-
   15

transmitted copies thereof filed with the Commission pursuant to EDGAR, except
to the extent permitted by Regulation S-T.

        (f)      If any event shall occur as a result of which it is necessary,
in the opinion of counsel for the Underwriters, to amend or supplement the
Prospectus or to file under the 1934 Act any document incorporated by reference
in the Prospectus in order to make the Prospectus not misleading in the light
of the circumstances existing at the time it is delivered to a purchaser, the
Company will forthwith amend or supplement the Prospectus or file such document
(in form and substance satisfactory to counsel for the Underwriters) so that,
as so amended or supplemented, the Prospectus 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, in the light of the circumstances
existing at the time it is delivered to a purchaser, not misleading, and the
Company will furnish to the Underwriters a reasonable number of copies of such
amendment or supplement.

         (g)      The Company will endeavor, in cooperation with the
Underwriters, to qualify the Securities and the Shares for offering and sale
under the applicable securities laws of such states and other jurisdictions of
the United States as the Underwriters may designate; provided, however, that
the Company shall not be obligated to qualify as a foreign corporation in any
jurisdiction in which it is not so qualified.  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 and the Shares.

         (h)      The Company will make generally available to its
securityholders as soon as practicable, but not later than 45 days (or 90 days,
in the case of a period that is also the Company's fiscal year) after the close
of the period covered thereby, an earnings statement of the Company and its
subsidiaries (in form complying with the provisions of Rule 158 of the 1933 Act
Regulations) covering a twelve-month period beginning not later than the first
day of the Company's fiscal quarter next following the "effective date" (as
defined in said Rule 158) of the Registration Statement.

         (i)      The Company will use the net proceeds received by it from the
sale of the Securities in the manner specified in the Prospectus 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 Pricing
Agreement, the

                                    -15-
   16

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.

        (k)      If the Company elects to rely upon Rule 462(b), the Company
shall both 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 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 Prospectus is required
to be delivered under the 1933 Act will file all documents required to be filed
with the Commission pursuant to Section 13, 14 or 15 of 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 and the Shares on the New York Stock Exchange and to cause the
Securities to be registered under the 1934 Act.

         (n)      During a period of 120 days from the date of the Pricing
Agreement, the Company will not, without the prior written consent of Merrill
Lynch, directly or indirectly, sell, offer to sell, grant any option for the
sale of, or otherwise dispose of, or enter into any agreement to sell, any
Securities, Purchase Contracts or Common Stock or any securities of the Company
similar to the Securities, Purchase Contracts or Common Stock or any security
convertible into or exchangeable or exercisable for Securities, Purchase
Contracts or Common Stock; provided, however, that such restriction shall not
affect the ability of the Company to take any such action (i) in connection
with any employee benefit, dividend reinvestment or stock purchase plan of the
Company or its subsidiaries, or (ii) in connection with the offering of the
Securities made in connection with the Prospectus.

         (o)      During a period of three years from the Closing Time, to make
generally available to the Underwriters copies of all reports and other
communications (financial or other) mailed to stockholders, and to deliver to
the 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 Underwriters may from time to time
reasonably request (such financial statements to be on a consolidated basis

                                    -16-
   17

to the extent the accounts of the Company and its subsidiaries are consolidated
in reports furnished to its stockholders generally or to the Commission).

         (p)     The Company will reserve and keep available at all times, free
of preemptive or other similar rights and liens and adverse claims, sufficient
shares of Common Stock to satisfy any obligations to issue Shares upon
settlement of the Purchase Contracts.

         (q)     The Company will supply the Underwriters with copies of all
correspondence to and from, and all documents delivered to and by, the
Commission in connection with the registration of the Securities under the 1933
Act.

         (r)     The Company will not take, directly or indirectly, any action
designed to, or that might reasonably be expected to, cause or result in
manipulation of the price of the Securities or the Common Stock.

         SECTION 4.  Payment of Expenses.  The Company agrees with the several
Underwriters to pay all expenses incident to the performance of its obligations
under this Agreement, the Pricing Agreement, the Purchase Contracts, the
Purchase Contract Agreement and the Pledge Agreement, including, without
limitation, expenses related to the following, if incurred: (i) the

the Blue Sky Survey and any Legal Investment Survey, (vi) the printing and
delivery to the Underwriters of copies of the Registration Statement as

                                    -17-

   18

the review, if any, by the National Association of Securities Dealers, Inc.
(the "NASD") of the terms of the sale of the Securities; (x) any fees payable
to the Commission; and (xi) the fees and expenses incurred in connection with
the listing of the Securities and the Shares on the New York Stock Exchange.

Company shall reimburse the Underwriters for all of their out-of-pocket

         Commission.

                     (viii)         The Registration Statement,
         including any Rule 462(b) Registration Statement, each of the
         incorporated documents and the Prospectus, and each amendment or
         supplement thereto (other than the financial statements and supporting
         schedules and other financial or statistical data included or
         incorporated by reference therein, or the exhibits to the Registration
         Statement, including any Form T-1, as to which no opinion need be
         rendered), as of their respective effective or issue dates, or when
         amended, as appropriate, complied as to form in all material respects
         with the requirements of the 1933 Act or the 1934 Act and the rules

         the requirements of the 1933 Act or the 1934 Act, as applicable, and
         the rules and regulations of the Commission thereunder; and such
         counsel has no reason to believe that any of such documents, when such
         documents became effective or were so filed, as the case may be,
         contained, in the case of the Registration Statement, 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, and, in the case of other documents which were
         filed under the 1934 Act with the Commission, an untrue statement of a
         material fact or omitted to state a material fact necessary in order
         to make the statements therein not misleading.

                                    -20-
   21

         reserved for issuance and, when issued and delivered by the Company in
         accordance with the provisions of the Purchase Contract Agreement and
         the Pledge Agreement, will be fully paid and non-assessable; the
         issuance of such Shares will not be subject to preemptive or other
         similar rights arising by law or, to the best of such counsel's
         knowledge, otherwise.

                      (xiii)         The issuance of the Securities is
         not subject to preemptive or other similar rights arising by law or,

         Contracts underlying the Securities, the offer of the Securities by
         the Company as contemplated herein and in the Prospectus, the issue
         and sale of the Shares by the Company pursuant to the Purchase
         Contracts; the execution, delivery and performance by the Company of
         all of the provisions of this Agreement, the Pricing Agreement, the
         Purchase Contracts, the Purchase Contract Agreement and the Pledge
         Agreement; the consummation of the transactions contemplated herein
         and therein; and the compliance by the Company with its obligations
         hereunder and thereunder will not result in any violation of the
         provisions of the charter or by-laws of the Company or any of its
         subsidiaries, or any applicable law, administrative regulation or
         administrative or court decree.

                      (xv)         The Rights to be issued with the
         Shares have been duly authorized and, upon issuance of such Shares,
         will be validly issued and conform to the description thereof in the
         Prospectus.

                      (xvi)         This Agreement and the Pricing
         Agreement have each been duly authorized, executed and delivered by
         the Company.

                      (xvi)         The certificate(s) used to evidence
         the Securities are in a form contemplated by the Purchase Contract
         Agreement and comply with all applicable statutory requirements and
         with the requirements of the New York Stock Exchange.

                      (xviii)         To the best of such counsel's
         knowledge, there are no actions, suits or proceedings before or by any
         court or governmental agency or body, domestic or foreign, pending or
         threatened which are required to be disclosed in the Registration
         Statement or the Prospectus, other than

                                    -21-

   22

         those disclosed therein, and all pending legal or governmental
         proceedings to which the Company or any of its subsidiaries is a party
         or to which any of their property is subject which are not described
         in the Registration Statement or the Prospectus, including ordinary
         routine litigation incidental to the business, are, considered in the
         aggregate, not material.

                      (xix)         The information in the Prospectus
         under the captions "MCN Corporation", "Use of Proceeds",
         "Capitalization", "Description of the Securities", "Description of the
         Purchase Contracts", "Description of Stock Purchase Contracts and
         Stock Purchase Units" and "Certain Provisions of the Purchase Contract
         Agreement and the Pledge Agreement", to the extent that they involve
         matters of law, summaries of legal matters, documents or proceedings,
         or legal conclusions, has been reviewed by such counsel and is correct
         in all material respects.

                      (xx)         To the best of such counsel's
         knowledge and information, there are no contracts, indentures,
         mortgages, loan agreements, notes, leases or other instruments
         required to be described or referred to or incorporated by reference
         in the Registration Statement or to be filed as exhibits thereto other
         than those described or referred to or incorporated by reference
         therein or filed as exhibits thereto; the descriptions thereof or
         references thereto are true and correct, and no default exists in the
         due performance or observance of any material obligation, agreement,
         covenant or condition contained in any contract, indenture, mortgage,
         loan agreement, note, lease or other instrument so described, referred
         to, filed or incorporated by reference.

                      (xxi)         The entry into the Purchase
         Contracts underlying the Securities, the offer of the Securities by
         the Company as contemplated herein and in the Prospectus, the issue
         and sale of the Shares by the Company pursuant to the Purchase
         Contracts; the execution, delivery and performance by the Company of
         all of the provisions of this Agreement, the Pricing Agreement, the
         Purchase Contracts, the Purchase Contract Agreement and the Pledge
         Agreement; the consummation of the transactions contemplated herein
         and therein; and the compliance by the Company with its obligations
         hereunder and thereunder have been duly authorized by all necessary
         corporate action of the Company and will not conflict with or
         constitute a breach of, or default under, or result in the creation or
         imposition of any lien, charge or encumbrance upon any property or
         assets of the Company or any of its subsidiaries pursuant to, any
         contract, indenture, mortgage, loan agreement, note, lease or other
         instrument to which the Company or any of its subsidiaries is a party
         or by which it or any of them may be

                                    -22-
   23

         bound, or to which any of the property or assets of the Company or any
         of its subsidiaries is subject, nor will such action result in any
         violation of the provisions of the charter or by-laws of the Company
         or any of its subsidiaries, or any applicable law, administrative
         regulation or administrative or court decree.

                     (xxii)         The Company and its subsidiaries
         possess all licenses, franchises, permits, certificates,
         authorizations, approvals, consents and orders of all governmental
         authorities or agencies necessary for the ownership or lease of the
         material properties owned or leased by each of them and for the
         operation of the business carried on by each of them as described in
         the Registration Statement and Prospectus 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, and consents 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.

                     (xxiv)         None of the Company or any of its
         subsidiaries is an "investment company" or under the "control" of an
         "investment company" as such terms are defined in the 1940 Act.

                     (xxiv)         The Company is presently exempt from
         the provisions of the Public Utility Holding Company Act of 1935
         (except Section 9 thereof) which would otherwise require it to
         register thereunder.

                     (xxv)         The Company is in compliance with
         all provisions of Section 1 of the Laws of Florida, Chapter 92-198, An
         Act Relating to Disclosure of Doing Business with Cuba.
                                                                 

         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 information provided pursuant to
         Rule 430A or Rule 434 (except for financial statements and related
         schedules and other financial or statistical data included or
         incorporated by reference therein, as to which counsel need express no
         opinion), at the time it became effective or at the Representation
         Date, contained an untrue statement of a material fact or omitted to
         state a material fact required


                                    -23-
   24

         to be stated therein or necessary to make the statements therein not
         misleading or that the Prospectus (except for financial statements and
         related schedules and other financial or statistical data included or
         incorporated by reference therein, as to which counsel need express no
         opinion), at the Representation Date (unless the term "Prospectus"
         refers to a prospectus which has been provided to the Underwriters by
         the Company for use in connection with the offering of the Securities
         which differs from the Prospectus on file at the Commission at the
         time the Registration Statement became effective, in which case at the
         time it is first provided to the Underwriters for such use) or at
         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.

                (2)       The favorable opinion, dated as of Closing Time, of
Skadden, Arps, Slate, Meagher & Flom, special counsel to the Company, in form
and substance satisfactory to counsel for the Underwriters, to the effect that:

                          (i)         The Registration Statement,
         including any Rule 462(b) Registration Statement, is effective under
         the 1933 Act; any required filing of the Prospectus pursuant to Rule
         424(b) has been made in the manner and within the time period required
         by Rule 424(b); and no stop order suspending the effectiveness of the
         Registration Statement has been issued under the 1933 Act or
         proceedings therefor initiated, to the best of such counsel's
         knowledge, or threatened by the Commission.

                          (ii)         The Registration Statement,
         including any Rule 462(b) Registration Statement and the Prospectus,
         and each amendment or supplement thereto (other than the financial
         statements and supporting schedules and other financial or statistical
         data included or incorporated by reference therein, or the exhibits to
         the Registration Statement, including any Form T-1, as to which no
         opinion need be rendered), as of their respective effective or issue
         dates, or when amended, as appropriate, complied as to form in all
         material respects with the requirements of the 1933 Act and the rules
         and regulations of the Commission thereunder.

                          (iii)         The statements in the Prospectus
         under the captions "Description of the Securities", "Description of
         the Purchase Contracts", "Description of Stock Purchase Contracts and
         Stock Purchase Units" and "Certain Provisions of the Purchase Contract
         Agreement and the Pledge Agreement", to the extent that they involve
         matters of law, summaries of legal matters, documents or proceedings,
         or
                                    -24-

   25

         legal conclusions, has been reviewed by such counsel and is correct in
         all material respects.

                          (iv)         Assuming that the Purchase Contract
         Agreement, the Purchase Contracts underlying the Securities being
         delivered at the Closing Time and at any Date of Delivery and the
         Pledge Agreement have been duly authorized, executed and delivered by
         the Company under Michigan law, and subject to the enforceability of
         the choice of law provisions thereof, each is a valid and legally
         binding agreement of the Company (and together they create, to the
         extent provided therein, a valid interest of the holders of the
         Securities in the Treasury Notes) enforceable against the Company in
         accordance with its terms, except as may be limited by bankruptcy,
         insolvency, reorganization, fraudulent transfer or conveyance or other
         similar laws now or hereafter in effect relating to creditors' rights
         and remedies generally and by general principles of equity (regardless
         of whether enforceability is considered in a proceeding at law or in
         equity); provided, however, that based on a review of applicable case
         law, and subject to the assumptions and qualifications outlined in a
         letter dated April 22, 1996, addressed to Moody's Investor Service
         (which will be attached as an exhibit to such opinion), upon the
         occurrence of a Termination Event, Section 365(e)(2) of the Bankruptcy
         Code (11 U.S.C. Section Section  101-1330, as amended) should not
         substantively limit the provisions of Sections 4.2 and 5.8 of the
         Purchase Contract Agreement and Section 4(a) of the Pledge Agreement
         that require termination of the Purchase Contracts and release of the
         Collateral Agent's security interest in the Treasury Notes;
         provided, however, that procedural restrictions respecting relief from
         the automatic stay under Section 362 of the Code may affect the 
         timing of the exercise of such rights and remedies.

                          (v)         Assuming that (1) the Pledge
         Agreement has been duly authorized, executed and delivered by the
         Purchase Contract Agent on behalf of each of the Holders, (2) the
         Purchase Contract Agent is duly incorporated and validly existing
         under the laws of the state of its incorporation, (3) the Purchase
         Contract Agent and each of the Holders has full power, authority and
         legal right (including, without limitation, any legal right dependent
         upon there being no necessary governmental approvals or filings and no
         conflict with laws, governing documents or contracts) to make and
         perform its obligations under the Pledge Agreement, (4) the Pledge
         Agreement is the legal, valid, binding and enforceable obligation of
         the Purchase Contract Agent on behalf of each of the Holders, and (5)
         the Purchase Contract Agent and each Holder has sufficient rights in
         the Treasury Notes for the security interest of the Collateral Agent
         for the benefit of the Company to attach, the "transfer" (within the
         meaning of Section 8-313
                                    -25-

   26

         of the UCC) of the Treasury Notes to the Collateral Agent for the
         benefit of the Company, together with the Pledge Agreement, will
         create a valid and perfected security interest in such Treasury Notes
         to secure the obligations of the Holders under the Purchase Contracts,
         subject to customary qualifications reasonably acceptable to the
         Underwriters.  References to (x) the "UCC" shall mean the Uniform
         Commercial Code as in effect on the date hereof in the State of New
         York and (y) "Financial Intermediary" shall mean Chemical Bank acting
         solely in its capacity as a "depositary" as defined in 31 C.F.R.
         Section  306 or similar federal regulations governing the transfer of
         U.S. Government book-entry securities.  "Transfer" of the Treasury
         Notes to the Collateral Agent for the benefit of the Company will
         occur upon the latest of (1) the making by The Federal Reserve Bank of
         New York of appropriate entries transferring such Treasury Notes on
         its books and records to the book-entry account of the Financial
         Intermediary at The Federal Reserve Bank of New York and (2) the
         sending of a confirmation by the Financial Intermediary to the
         Collateral Agent for the benefit of the Company of the purchase by the
         Collateral Agent for the benefit of the Company of such Treasury Notes
         and the identification by book-entry by the Financial Intermediary of
         such Treasury Notes as belonging to the Collateral Agent for the
         benefit of the Company.

                          (vi)         The Shares and the Securities
         conform in all material respects to the description thereof contained
         in the Prospectus and the Registration Statement.

                          (vii)         No authorization, approval, consent,
         order, registration or qualification of or with any court or federal
         or New York State governmental authority or agency is required for the
         entry into the Purchase Contracts underlying the Securities, the
         issuance and sale of the Securities hereunder or the issuance and sale
         of the Shares by the Company pursuant to such Purchase Contracts or
         the consummation by the Company of any transactions contemplated under
         this Agreement, such Purchase Contracts, the Purchase Contract
         Agreement and the Pledge Agreement, except such as have been obtained
         and made under the federal securities laws or such as may be required
         under state or foreign securities or Blue Sky laws.

                          (viii)         The statements in the Prospectus
         under the caption "Certain Federal Income Tax Consequences" have been
         reviewed by such counsel and, insofar as they constitute legal
         conclusions or matters of law, fairly summarize the matters referred
         to therein.

         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

                                    -26-
   27

         information provided pursuant to Rule 430A or Rule 434 (except for
         financial statements and related schedules and other financial or
         statistical data included or incorporated by reference therein, as to
         which counsel need express no opinion), at the time it became
         effective or at the Representation Date, 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 Prospectus (except for financial statements and
         related schedules and other financial or statistical data included or
         incorporated by reference therein, as to which counsel need express no
         opinion), at the Representation Date (unless the term "Prospectus"
         refers to a prospectus which has been provided to the Underwriters by
         the Company for use in connection with the offering of the Securities
         which differs from the Prospectus on file at the Commission at the
         time the Registration Statement became effective, in which case at the
         time it is first provided to the Underwriters for such use) or at
         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.

                (3)       The favorable opinion, dated as of Closing Time, of
LeBoeuf, Lamb, Greene & MacRae, L.L.P., counsel for the Underwriters, with
respect to the validity of the Securities (including the Purchase Contracts and
the Shares to be issued pursuant to the Purchase Contract Agreement), the
Registration Statement, the Prospectus and other related matters as you may
require, and the Company shall have furnished to such counsel such documents as
they request for the purpose of enabling them to pass upon such matters.  In
giving their opinion, LeBoeuf, Lamb, Greene & MacRae, L.L.P. may rely as to
matters of Michigan law upon the opinion of Daniel L. Schiffer, Esq., which
opinion shall be in form and substance satisfactory to counsel for the
Underwriters.

        (c)      At Closing Time, there shall not have been, since the date
hereof or since the respective dates as of which information is given in the
Registration Statement and the Prospectus, any material adverse change or any
development which would reasonably be expected to result in any prospective
material adverse change in the condition, 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, and the Underwriters shall have received a
certificate of the President or a Vice President of the Company and of the
chief financial or chief accounting officer of the Company, dated as of Closing
Time, to the effect that (i) there has been no such material adverse change,
(ii) the representations and warranties in Section 1 are

                                    -27-

   28

true and correct with the same force and effect as though expressly made at and
as of the Closing Time, (iii) the Company has complied with all agreements and
satisfied all conditions on its part to be performed or satisfied at or prior
to the Closing Time, and (iv) no stop order suspending the effectiveness of the
Registration Statement has been issued and no proceedings for that purpose have
been initiated or threatened by the Commission.

        (d)      At the time of the execution of this Agreement, the
Representatives shall have received from Deloitte & Touche LLP a letter dated
such date in form and substance satisfactory to the Representatives, to the
effect set forth below and as to such other matters as the 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;

                 (ii)     In their opinion, the consolidated financial
         statements and any supplementary financial information and schedules
         audited (and, if applicable, prospective financial statements and/or
         pro forma financial information examined) by them and included or
         incorporated by reference in the Registration Statement or the
         Prospectus comply as to form in all material respects with the
         applicable accounting requirements of the 1933 Act and the 1934 Act
         and the related published rules and regulations thereunder; and if
         applicable, they have made a review in accordance with standards
         established by the American Institute of Certified Public Accountants
         of the consolidated interim financial statements, selected financial
         data, pro forma financial information, prospective financial
         statements, consolidating financial statements and/or condensed
         financial statements derived from audited financial statements of the
         Company for the periods specified in such letter, as indicated in
         their reports thereon, copies of which have been furnished to the
         Representatives;

                 (iii) The unaudited selected financial information with
         respect to the consolidated results of operations and financial
         position of the Company for the five most recent fiscal years included
         in the Prospectus and included or incorporated by reference in the
         Company's Annual Report on Form 10-K for the most recent fiscal year
         agrees with the corresponding amounts (after restatement where
         applicable) in the audited consolidated financial statements for such
         five fiscal years which were included or incorporated by reference in
         the Company's Annual Reports on Form 10-K for such fiscal years;

                 (iv) On the basis of limited procedures, not constituting an
         audit in accordance with generally accepted

                                    -28-

   29

         auditing standards, including a reading of the unaudited consolidated
         financial statements and other information referred to below, a
         reading of the latest available unaudited interim consolidated
         financial statements of the Company and its subsidiaries, inspection
         of the minute books 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 consolidated financial
                 statements set forth in the Company's Quarterly Reports on
                 Form 10-Q incorporated by reference in the Registration
                 Statement and the Prospectus as amended or supplemented do not
                 comply as to form in all material respects with the applicable
                 accounting requirements of the 1934 Act as they apply to Form
                 10-Q and the 1934 Act Regulations or are not 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 Prospectus as amended or supplemented;

                          (B)     any other unaudited income statement data and
                 balance sheet items included in the Prospectus do not agree
                 with the corresponding items in the unaudited consolidated
                 financial statements from which such data and items were
                 derived, and any such unaudited data and items were not
                 determined on a basis substantially consistent with the basis
                 for the corresponding amounts in the audited consolidated
                 financial statements included or incorporated by reference in
                 the Registration Statement and the Prospectus as amended or
                 supplemented;

                          (C)  any unaudited pro forma consolidated condensed
                 financial statements or any unaudited pro forma consolidating
                 financial statements included or incorporated by reference in
                 the Prospectus as amended or supplemented do not comply as to
                 form in all material respects with the applicable accounting
                 requirements of the 1933 Act and the 1933 Act Regulations or
                 the pro forma adjustments have not been properly applied to
                 the historical amounts in the compilation of those statements;

                          (D)     As of a specified date not more than five
                 days prior to the date of delivery of such letter, there has
                 been any decrease or increase in the common stock (except for
                 any increases in connection with any employee benefit,
                 dividend reinvestment or stock purchase plan of the Company)
                 or any increase or decrease in redeemable cumulative preferred
                 securities or long-term debt including capital lease
                 obligations (except for sinking fund and installment
                 requirements under their long-term debt agreement, terms of
                 the preferred securities of MCN Michigan Limited Partnership
                 and purchases in the open market in anticipation thereof) or
                 any increase in short-term debt, or any decrease in

                 dividends declared to shareholders) of the Company and its
                 consolidated subsidiaries, in each case as compared with the
                 corresponding amounts shown in the latest consolidated
                 statement of financial position incorporated by reference in
                 the Registration Statement and the Prospectus as amended or
                 supplemented, except in each case for increases or decreases
                 which the Prospectus as amended or supplemented, including
                 financial information incorporated by reference, discloses
                 have occurred or may occur or which are described in such
                 letter; and

                          (E)     for the period from the date of the latest
                 consolidated financial statements included or incorporated by
                 reference in the Prospectus as amended or supplemented to the
                 end of the latest period for which consolidated financial
                 statements are available there were any decreases in
                 consolidated operating revenues, operating income, net income
                 or earnings available for Common Stock of the Company and its
                 consolidated subsidiaries, or any increases in any items
                 specified by the Representatives, in each case as compared
                 with the corresponding period in the preceding year and with
                 any other period of corresponding length specified by the
                 Representatives, except in each case for increases or
                 decreases which the Prospectus as amended or supplemented,
                 including financial information incorporated by reference,
                 discloses have occurred or may occur or which are described in
                 such letter.

                          (F)     The unaudited consolidated financial
                 statements referred to in Clause (E) are not stated on a basis
                 substantially consistent with the audited consolidated
                 financial statements incorporated by reference in the
                 Registration Statement and the Prospectus as amended or
                 supplemented.

                 (v)      In addition to the limited procedures, inspection of
         minute books, inquiries and other procedures referred to in clause
         (iii) and (iv) above, they have carried out certain other specified
         procedures, not constituting an audit in accordance with generally
         accepted auditing standards, with respect to certain amounts,
         percentages and financial information which are derived from the
         general accounting records of the Company and its subsidiaries, which
         appear in the Prospectus as amended or supplemented and the
         Registration Statement, in the Company's Annual Report on Form 10-K
         for the latest year ended and in the Company's Quarterly Reports on
         Form 10-Q since the latest Annual Report on Form 10-K and which are
         specified by the Representatives, and have compared certain of such
         amounts, percentages and financial information with the accounting
         records of the Company and its subsidiaries and have found them to be
         in agreement.

         (e)      At the Closing Time, the Representatives shall have received
from Deloitte & Touche LLP a letter, dated as of the Closing Time, to the
effect that they reaffirm the statements made in the letter furnished pursuant
to subsection (d) of this Section, except that the specified date referred to

as they may require for the purpose of enabling them to pass upon the issuance
and sale of the Securities as herein contemplated and related proceedings, or
in order to evidence the accuracy of any of the representations or warranties,
or the fulfillment of any of the conditions herein contained; and all
proceedings taken by the Company in connection with the issuance and sale of
the Securities as herein contemplated shall be satisfactory in form and
substance to the Underwriters and counsel for the Underwriters.

         (g)      On or after the date hereof (i) no downgrading shall have
occurred in the rating accorded to any of the Company's securities by any
"nationally recognized statistical rating organization," as that term is
defined by the Commission for purpose of Rule 436(g)(2) under the 1933 Act, and
(ii) no such organization shall have publicly announced that it has under
surveillance or review, with possible negative implications, its ratings of any
of the Company's securities.

         (h)      At Closing Time, the Securities and the Shares shall have been
approved for listing on the New York Stock Exchange upon notice of issuance.

         (i)      The NASD shall not have raised any objection with respect to
the fairness and reasonableness of the underwriting terms and arrangements.

         (j)      In the event that the Underwriters exercise their option
provided in Section 2(b) hereof to enter into all or any portion of the
Purchase Contracts underlying the Option Securities, the representations and
warranties of the Company contained herein and the statements in any
certificates furnished by the Company hereunder shall be true and correct as

         President or a Vice President of the Company and the chief financial
         or chief accounting officer of the Company confirming that the
         certificate delivered at the Closing Time pursuant to Section 5(c)
         hereof is true and correct as of, and as if made on, such Date of
         Delivery.

                (2)       The favorable opinion of Daniel L. Schiffer, Esq.,
         Senior Vice President, General Counsel and Secretary for the Company,
         in form and substance satisfactory to counsel for the Underwriters,
         dated such Date of Delivery, relating to the Option Securities and
         otherwise to the same effect as the opinion required by Section
         5(b)(1) hereof.

                 (3)       The favorable opinion of Skadden, Arps, Slate,
         Meagher & Flom, special counsel for the Company, in form and substance
         satisfactory to counsel for the Underwriters, dated such Date of
         Delivery, relating to the Option Securities and otherwise to the same

         Section 5(i)(e) shall be a date not more than five days prior to such
         Date of Delivery.

         If any condition specified in this Section 5 shall not have been
fulfilled when and as required to be fulfilled, this Agreement may be
terminated by the Underwriters by notice to the Company at any time at or prior
to Closing Time, and such termination shall be without liability of any party

                                    -32-
   33

         SECTION 6.  Indemnification.

         (a)  The Company agrees to indemnify and hold harmless each Underwriter
and each person, if any, who controls any Underwriter within the meaning of
Section 15 of the 1933 Act as follows:

                      (i)         against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         the Registration Statement (or any amendment thereto), including the
         information deemed to be part of the Registration Statement pursuant
         to Rule 430(A) of the 1933 Act Regulations, if applicable, or the
         omission or alleged omission therefrom of a material fact required to
         be stated therein or necessary to make the statements therein not
         misleading or arising out of any untrue statement or alleged untrue
         statement of a material fact contained in any preliminary prospectus
         or the Prospectus (or any amendment or supplement thereto), or the
         omission or alleged omission therefrom of a material fact necessary in
         order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading;

                      (ii)         against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, to the extent of the
         aggregate amount paid in settlement of any litigation, or any
         investigation or proceeding by any governmental agency or body,
         commenced or threatened, or of any claim whatsoever based upon any
         such untrue statement or omission, or any such alleged untrue
         statement or omission, if such settlement is effected with the written
         consent of the Company; and

                      (iii)         against any and all expense whatsoever, as
         incurred (including, subject to Section 6(c) hereof, the fees and
         disbursements of counsel chosen by Merrill Lynch), reasonably incurred
         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 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 the 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 Underwriter through Merrill Lynch expressly for use in the
Registration Statement (or any amendment thereto) or any preliminary prospectus
or the Prospectus (or any amendment or

                                    -33-

   34

supplement thereto).  The foregoing indemnity with respect to any untrue
statement contained in or omission from a preliminary prospectus shall not
inure to the benefit of any Underwriter (or any person controlling such
Underwriter) from whom the person asserting any such loss, liability, claim,
damage or expense purchased any of the Securities that are the subject thereof
if such person was not sent or given a copy of the Prospectus (or the
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 Securities to such person and the untrue
statement contained in or omission from such preliminary prospectus was
corrected in the Prospectus (or the Prospectus as amended or supplemented).

        (b)      Each 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 against any and all loss,
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) or any preliminary prospectus
or the Prospectus (or any amendment or supplement thereto) in reliance upon and
in conformity with written information furnished to the Company by such
Underwriter through Merrill Lynch expressly for use in the Registration
Statement (or any amendment thereto) or such preliminary prospectus or the
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 which it may have otherwise than on account of this
indemnity agreement.  An indemnifying party may participate at its own expense
in the defense of any such action.  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.

         SECTION 7.  Contribution.  In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 6 is for any reason held to be unenforceable by the indemnified parties
although applicable in accordance with its terms, the Company and the
Underwriters shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by said indemnity agree-

                                    -34-
   35


ment incurred by the Company and one or more of the Underwriters, as incurred, 
in such proportions that the Underwriters are responsible for that portion
represented by the percentage that the underwriting compensation paid by the
Company appearing on the cover page of the Prospectus bears to the initial
public offering price appearing thereon and the Company is responsible for the
balance; provided, however, that 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, each person, if
any, who controls an Underwriter within the meaning of Section 15 of the 1933
Act shall have the same rights to contribution as such 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 shall have the same rights to
contribution as the Company.

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

         SECTION 9.  Termination of Agreement.

        (a)  The Representatives may terminate this Agreement, by notice to the
Company at any time at or prior to Closing Time (i) if there has been, since
the date of this Agreement or since the respective dates as of which
information is given in the Registration Statement, any material adverse change
or any development which could reasonably be expected to result in a
prospective material adverse change in the business or the condition, 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) if 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 Underwriters, 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, NASD or the New
York Stock Exchange, or if trading generally on either the American Stock
Exchange or the New York Stock Exchange has been

                                    -35-
   36

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 order of the Commission 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 Pricing Agreement are terminated
pursuant to this Section, 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 and 7 shall survive such termination and remain in
full force and effect.

         SECTION 10. Default by One or More of the Underwriters.  If one or more
of the Underwriters shall fail at the Closing Time to enter into the Purchase
Contracts underlying the Initial Securities which it or they are obligated to
enter into under this Agreement and the Pricing Agreement (the "Defaulted
Securities"), the Representatives shall have the right, within 24 hours
thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to enter into all, but not less than
all, of the Purchase Contracts underlying such Defaulted Securities in such
amounts as may be agreed upon and upon the terms herein set forth; if, however,
the 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 total number of Initial Securities, the non-defaulting Underwriters
shall be obligated to enter into Purchase Contracts underlying the full amount
thereof in the proportions that their respective underwriting obligations
hereunder bear to the underwriting obligations of all non-defaulting
Underwriters, or

                (b)       if the number of Defaulted Securities exceeds 10% of
the Initial Securities, this Agreement shall terminate without liability on the
part of any non-defaulting Underwriter.

                 No action taken pursuant to this Section shall relieve any
defaulting 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, either the Representatives or the Company shall
have the right to postpone the Closing Time for a period not exceeding seven
days in order to effect any required changes in the Registration Statement or
Prospectus or in any other documents or arrangements.
                  
         SECTION 11.  Notices.  All notices and other communications hereunder
shall be in writing and shall be deemed to have been

         SECTION 12.  Parties.  This Agreement and the Pricing Agreement shall
each inure to the benefit of and be binding upon the Underwriters and the
Company and their respective successors.  Nothing expressed or mentioned in
this Agreement or the Pricing Agreement is intended or shall be construed to
give any person, firm or corporation, other than the Underwriters and the
Company and their respective successors and the controlling persons and

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
