through the facilities of The Depository Trust Company unless the 
Representatives shall otherwise instruct.

     4.   Offering by Underwriters. It is understood that the several
Underwriters propose to offer the Securities for sale to the public as set forth
in the Prospectus.

     5.   Agreements. The Offerors agree with the several Underwriters that:

          (a) Prior to the termination of the offering of the Securities, the
Offerors will not file any amendment of the Registration Statement or supplement
to the Prospectus or any Rule 462(b) Registration Statement unless the Offerors
have furnished you a copy for your review prior to filing and will not file any
such proposed amendment or supplement to which you reasonably object. Subject to
the foregoing sentence, if the Registration Statement has become or becomes
effective pursuant to Rule 430A, or filing of the Prospectus is otherwise
required under Rule 424(b), the Offerors will cause the Prospectus, properly
completed, and any supplement thereto to be filed with the Commission pursuant
to the applicable paragraph of Rule 424(b) within the time period prescribed and
will provide evidence satisfactory to the Representatives of such timely filing.
The Offerors will promptly advise the Representatives (1) when the Prospectus,
and any supplement thereto, shall have been filed (if required) with the
Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration
Statement shall have been filed with the Commission, (2) when, prior to
termination of the offering of the Securities, any amendment to the Registration
Statement shall have been filed or become effective, (3) of any request by the
Commission or its staff for any amendment of the Registration Statement, or any
Rule 462(b) Registration Statement, or for any supplement to the Prospectus or
for any additional information, (4) of the issuance by the Commission of any
stop order suspending the effectiveness of the Registration Statement or the
institution or threatening of any proceeding for that purpose and (5) of the
receipt by either of the Offerors of any notification with respect to the
suspension of the qualification of the Securities for sale

                                       11
   12
in any jurisdiction or the institution or threatening of any proceeding for such
purpose. The Offerors will use their respective best efforts to prevent the
issuance of any such stop order or the suspension of any such qualification and,
if issued, to obtain as soon as possible the withdrawal thereof.

          (b) If, at any time when a prospectus relating to the Securities is
required to be delivered under the Act any event occurs as a result of which the
Prospectus as then supplemented would include any untrue statement of a material
fact or omit to state any material fact necessary to make the statements therein
in the light of the circumstances under which they were made not misleading, or
if it shall be necessary to amend the Registration Statement or supplement the
Prospectus to comply with the Act or the Exchange Act or the respective rules
thereunder, the Offerors promptly will (1) notify the Representatives of such
event, (2) prepare and file with the Commission, subject to the second sentence
of paragraph (a) of this Section 5, an amendment or supplement which will
correct such statement or omission or effect such compliance and (3) supply any
supplemented Prospectus to you in such quantities as you may reasonably request.

          (c) As soon as practicable, the Company will make generally available
to its security holders and to the Representatives an earnings statement or
statements of the Company and its subsidiaries which will satisfy the provisions
of Section 11(a) of the Act and Rule 158 under the Act.

          (d) The Offerors will furnish to the Representatives and counsel for
the Underwriters, without charge, copies of the Registration Statement
(including exhibits thereto) and to each other Underwriter a copy of the
Registration Statement (without exhibits thereto) and, so long as delivery of a
prospectus by an Underwriter or dealer may be required by the Act, as many
copies of each Preliminary Prospectus and the Prospectus and any supplement
thereto as the Representatives may reasonably request. The Company will pay the
expenses of printing or other production of all documents relating to the
offering.

          (e) The Offerors will arrange, if necessary, for the qualification of
the Securities for sale under the laws of such jurisdictions as the
Representatives may designate, will maintain such qualifications in effect so
long as required for the distribution of the Securities and will pay any fee of
the National Association of Securities Dealers, Inc., in connection with its
review of the offering; provided that in no event shall either of the Offerors
be obligated to qualify to do business in any jurisdiction where it is not now
so qualified or to take any action that would subject it to service of process
in suits, other than those arising out of the offering or sale of the
Securities, in any jurisdiction where it is not now so subject.

          (f) Neither the Trust nor the Company will, without the prior written
consent of Salomon Smith Barney Inc., for a period of 30 days following the
Closing Date, offer, sell or contract to sell, or otherwise dispose of (or enter
into any transaction which is

                                       12
   13
designed to, or might reasonably be expected to, result in the disposition
(whether by actual disposition or effective economic disposition due to cash
settlement or otherwise) by the Company or the Trust or any affiliate thereof or
any person in privity with the Company or the Trust or any affiliate thereof)
directly or indirectly, or announce the offering of, any preferred securities or
preferred stock or any other securities (including any backup undertakings of
such preferred stock or other securities) of the Company or the Trust, in each
case, that are substantially similar to the Preferred Securities, or any
securities convertible into, or exchangeable for the preferred securities or any
such substantially similar securities.

     6.   Conditions to the Obligations of the Underwriters. The 
obligations of the Underwriters to purchase the Securities shall be subject to 
the accuracy of the representations and warranties on the part of the Offerors 
contained herein as of the Execution Time and the Closing Date, to the accuracy 
of the statements of the Offerors made in any certificates pursuant to the 
provisions hereof, to the performance by the Offerors of their respective 
obligations hereunder and to the following additional conditions:

          (a) If filing of the Prospectus, or any supplement thereto, is
required pursuant to Rule 424(b), the Prospectus, and any such supplement, will
be filed in the manner and within the time period required by Rule 424(b) and no
stop order suspending the effectiveness of the Registration Statement shall have
been issued and no proceedings for that purpose shall have been instituted or
threatened.

          (b) The Company shall have furnished to the Representatives the
opinion of Daniel L. Schiffer, Senior Vice President and General Counsel for the
Company dated the Closing Date and addressed to the Representatives to the
effect that:

                  (i) The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of the State
         of Michigan.

                  (ii) The Company has corporate power and authority to own,
         lease and operate its properties and to conduct its business as
         described in the Registration Statement and the Prospectus.

                  (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,
         individually or in the aggregate, result in a Material Adverse Effect.

                  (iv) The authorized, issued and outstanding capital stock of
         the Company is as set forth in the Prospectus (except for subsequent
         issuances, if any, pursuant to employee benefit plan or dividend
         reinvestment and stock purchase plan

                                       13
   14
         transactions), and the shares of issued and outstanding capital stock
         of the Company have been duly authorized and validly issued and are
         fully paid and non-assessable.

                  (v) Each subsidiary of the Company has been duly incorporated
         and is validly existing as a corporation in good standing under the
         laws of the jurisdiction of its incorporation, has the corporate power
         and authority to own, lease and operate its properties and to conduct
         its business as presently conducted and as described in the
         Registration Statement and the Prospectus, and 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 to so qualify or be in good standing
         would not have a Material Adverse Effect; 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 (except for pledges of stock of special purpose
         corporations for the purpose of securing project financings that are
         either non-recourse or recourse only with respect to the special
         purpose corporation), lien, encumbrance, claim or equity.

                  (vi) The Trust is not required to be qualified and in good
         standing as a foreign company in Michigan, except to the extent that
         the failure to so qualify or be in good standing would not have,
         individually or in the aggregate with such other failures, a material
         adverse effect on the financial position or business operations of the
         Trust; and the Trust is not a party to or otherwise bound by any
         agreement other than those described in the Prospectus.

                  (vii) The Declaration has been duly authorized, executed and
         delivered by the Company and the Trustees and is a valid and binding
         obligation of the Company, enforceable against the Company and each of
         the Regular Trustees in accordance with its terms, except as
         enforcement thereof may be limited by the Bankruptcy Exceptions; and
         the Declaration has been duly qualified under the 1939 Act.

                  (viii) All legally required proceedings in connection with the
         authorization, issuance and validity of the Securities and the sale of
         the Securities in accordance with this Agreement (other than the filing
         of post-issuance reports, the non-filing of which would not render the
         Securities invalid) have been taken and all legally required orders,
         consents or other authorizations or approvals of any other public
         boards or bodies in connection with the authorization, issuance and
         validity of the Securities and the sale of the Securities in accordance
         with this Agreement (other than in connection with or in compliance
         with the provisions of the securities or Blue Sky

                                       14
   15
         laws of any jurisdictions, as to which no opinion need be expressed)
         have been obtained and are in full force and effect.

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

                  (x) The Registration Statement as of its effective date and
         the Prospectus and each amendment or supplement thereto as of its issue
         date (in each case, other than the financial statements and the notes
         thereto, the financial schedules, and any other financial data included
         or incorporated by reference therein, as to which such counsel need
         express no belief), complied as to form in all material respects with
         the requirements of the 1933 Act and the 1933 Act Regulations; and the
         Declaration, the Subordinated Indenture, the Preferred Securities
         Guarantee Agreement and the Statements of Eligibility on Forms T-1 with
         respect to each of the Institutional Trustee, the Debt Trustee, and the
         Guarantee Trustee filed with the Commission as part of the Registration
         Statement complied as to form in all material respects with the
         requirements of the 1939 Act and the 1939 Act Regulations.

                  (xi) Each of the documents incorporated by reference in the
         Registration Statement or the Prospectus at the time they were filed or
         last amended (other than the financial statements and the notes
         thereto, the financial schedules, and any other financial and
         statistical data included or incorporated by reference therein, as to
         which such counsel need express no belief) complied as to form in all
         material respects with the requirements of the 1934 Act, and the 1934
         Act Regulations, as applicable; 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 a registration statement which became effective under the 1933 Act,
         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 Exchange 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.

                  (xii) MCN and each of the MCN Trusts meet the registrant
         requirements for use of Form S-3 under the 1933 Act Regulations.

                  (xiii) The Common Securities, the Preferred Securities, the
         Subordinated Debt Securities, each of the Guarantees, the Declaration,
         the Subordinated Indenture and each of the Guarantee Agreements conform
         in all material respects to the descriptions thereof contained in the
         Prospectus.

                                       15
   16
                  (xiv) The information in the Prospectus under the captions

         Factors", "Use of Proceeds", "Capitalization", "Description of the
         Preferred Securities", "Description of Guarantee", "Description of the
         Junior Subordinated Debt Securities" and "Effect of Obligations under

         Guarantee", 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.

                  (xv) All of the issued and outstanding Common Securities of
         the Trust are directly owned by the Company free and clear of any
         security interest, mortgage, pledge, lien, encumbrance, claim or
         equitable right.

                  (xvi) This Agreement has been duly authorized, executed and
         delivered by each of the Trust and the Company.

                  (xvii) Each of the Guarantee Agreements has been duly
         authorized, executed and delivered by the Company; the Preferred
         Securities Guarantee Agreement, assuming it is duly authorized,
         executed, and delivered by the Guarantee Trustee, constitutes a valid
         and binding obligation of the Company, enforceable against the Company
         in accordance with its terms, except to the extent that enforcement
         thereof may be limited by Bankruptcy Exceptions; and the Preferred
         Securities Guarantee Agreement has been duly qualified under the 1939
         Act.

                  (xviii) The Subordinated Indenture has been duly executed and
         delivered by the Company and, assuming due authorization, execution,
         and delivery thereof by the Subordinated Indenture Trustee, is a valid
         and binding obligation of the Company, enforceable against the Company
         in accordance with its terms, except to the extent that enforcement
         thereof may be limited by the Bankruptcy Exceptions; and the Indenture
         has been duly qualified under the 1939 Act.

         contemplated by the Subordinated Indenture, have been duly authorized,
         executed and delivered by the Company and, when authenticated by the
         Subordinated Indenture Trustee in the manner provided for in the
         Subordinated Indenture and delivered against payment therefor as
         provided in this Agreement, will constitute valid and binding
         obligations of the Company, enforceable against the Company in
         accordance with their terms, except to the extent that enforcement
         thereof may be limited by the Bankruptcy Exceptions.

                  (xx) The execution, delivery and performance of this
         Agreement, the Declaration, the Preferred Securities, the Common
         Securities, the Subordinated

                                       16
   17
         Indenture, the Subordinated Debt Securities, the Guarantee Agreements,
         and the Guarantees; the consummation of the transactions contemplated
         herein and therein, and the compliance by each of the Offerors with
         their respective obligations hereunder and thereunder do not and will
         not conflict with, result in a breach of, or constitute a default under
         or require the consent of any party under the Certificate of Trust of
         the Trust or the Articles of Incorporation or by-laws of the Company
         and its subsidiaries, or any contract, indenture, mortgage, agreement,
         note, lease or other instrument to which the Trust, the Company or any
         of its subsidiaries is a party or by which any of them may be bound, or
         any applicable law, rule or regulation, or any judgment, order or
         decree of any government, governmental instrumentality or court,
         domestic or foreign, having jurisdiction over the Trust, the Company or
         any of its subsidiaries or any of their respective properties or assets
         or did or will result in the creation or imposition of any lien on the
         properties or assets of the Trust, the Company or any of its
         subsidiaries.

                  (xxi) 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 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.

                  (xxii) 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.

                  (xxiii) 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,

                                       17
   18
         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 Trust or 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.

                  (xxv) 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.

                  (xxvi) 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 Rule 430A Information and the
         Rule 424 Information (if applicable) (except for financial statements
         and related schedules and other financial and 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 Execution Time,
         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 or any
         amendment or supplement thereto (except for financial statements and
         related schedules and other financial and statistical data included or
         incorporated by reference therein, as to which counsel need express no
         opinion), at the time the Prospectus was issued, at the time of any
         such amended or supplemented Prospectus was issued or on the Closing
         Date, 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.

                  The foregoing opinions may be limited to the laws of Delaware,
Michigan and the federal law of the United States. In giving such opinion, such
counsel may rely, as to matters of Delaware Law, upon the opinion of Skadden,
Arps, Slate, Meagher & Flom LLP, special counsel to the Offerors, in which case
the opinion shall state that such counsel believes that you and such counsel are
entitled to so rely.

                                       18
   19
          (c) The Company shall have furnished to the Representatives the
opinion of Skadden, Arps, Slate, Meagher & Flom LLP, counsel to the Offerors,
dated the Closing Date and addressed to the Representatives, to the effect that:

                   (i) The Registration Statement, as of its Effective Date, and
         the Prospectus, as of the date of the Prospectus Supplement (other than
         the financial statements and supporting schedules and other financial
         and 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), appeared on their face to be
         appropriately responsive in all material respects to the requirements
         of the 1933 Act and the rules and regulations of the Commission
         thereunder.

                   (ii) The statements in the Prospectus under the captions "The
         MCN Trusts", "Description of the Preferred Securities" (except under
         the subsection "Book-Entry Only Issuance-The Depository Trust
         Company"), "Description of Guarantee", "Description of the Junior
         Subordinated Debt Securities", "Effect of Obligations Under the
         Subordinated Debt Securities and the Preferred Securities Guarantee",
         "Description of MCN Debt Securities" (except under the second and third
         paragraphs under the subsection "Book-Entry Debt Securities"),
         "Particular Terms of the Subordinated Debt Securities", "Description of
         MCN Trust Preferred Securities" and "Description of the Preferred

         the Registration Statement was declared effective under the 1933 Act at
         11:00 a.m., Eastern Standard Time on March 18, 1998 and, to the best of
         such counsel's knowledge, no stop order suspending the effectiveness of
         the Registration Statement has been issued and no proceedings for that
         purpose have been instituted or are pending or threatened by the
         Commission. Such counsel shall also state that the Prospectus has been
         filed in the manner and in the time period required by Rule 424(b).

         Moreover, such counsel shall confirm that no facts have come to such
         counsel's attention that would lead such counsel to believe that the
         Registration Statement, including any Rule 430A Information and 434
         Information (if applicable) (except for financial statements and
         related schedules and other financial and 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 Execution Time,
         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 or any
         amendment or supplement thereto (except for financial statements and
         related schedules and other financial and statistical data included or
         incorporated by reference therein, as to which counsel need express no
         opinion), at the time the Prospectus was issued, at the time of any
         amended or supplemented Prospectus was issued or on the Closing Date,
         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.

          (d) The Company shall have furnished to the Representatives the
opinion of Skadden, Arps, Slate, Meagher & Flom LLP, special tax counsel to the
Company, dated the Closing Date and in form and substance satisfactory to
counsel for the Underwriter, to the effect that the statements in the Prospectus
under the caption "Certain Federal Income Tax Considerations" have been reviewed
by such counsel and, insofar as they constitute legal conclusions or matters of
law, based upon current law and the assumptions stated or referred to therein,
fairly summarize the matters referred to therein. Such opinion may be
conditioned on, among other things, the initial and continuing accuracy of the
facts, financial and other information, covenants and representations set forth
in the certificates of officers of the Company and the Trust and other documents
deemed necessary for such opinion.

         with trust powers, duly organized, validly existing and in good
         standing under the laws of the State of Delaware with all necessary

         perform its obligations under the terms of the Declaration and the
         Preferred Securities Guarantee Agreement.

              (ii) The execution, delivery and performance by the Institutional
         Trustee of the Declaration and the execution, delivery and performance

         Agreement have been duly authorized by all necessary corporation action
         on the part of the Institutional Trustee and the Guarantee Trustee,
         respectively. The Declaration and the Preferred Securities Guarantee
         Agreement have been duly executed and delivered by the Institutional
         Trustee and the Guarantee Trustee, respectively, and constitute the
         legal, valid and binding obligations of the Institutional Trustee and
         the Guarantee Trustee, respectively, enforceable against the
         Institutional Trustee and the Guarantee Trustee, respectively, in
         accordance with their terms, except to the extent the enforcement
         thereof may be limited by the Bankruptcy Exceptions.

              (iii) The execution, delivery and performance of the Declaration
         and the Preferred Securities Guarantee Agreement by the Institutional
         Trustee and the Guarantee Trustee, respectively, do not conflict with
         or constitute a breach of the Articles of Organization or Bylaws of the
         Institutional Trustee and the Guarantee Trustee, respectively.

              (iv) No consent, approval or authorization of, or registration
         with or notice to, any Delaware or federal banking authority is
         required for the execution, delivery or performance by the
         Institutional Trustee and the Guarantee Trustee of the Declaration and
         the Preferred Securities Guarantee Agreement.

          (f) The Representatives shall have received from LeBoeuf, Lamb, Greene

Representatives may reasonably require, and the Company shall have furnished to
such counsel such documents as they request for the purpose of

                                       22
   23

shall be rendered to the Underwriters at the request of the Company and shall so
state therein.

examined the Registration Statement, the Prospectus, any supplements to the
Prospectus and this Agreement and that:

              (i) The representations and warranties of the Company or the
         Trust, as the case may be, in this Agreement are true and correct in
         all material respects on and as of the Closing Date with the same
         effect as if made on the Closing Date and the Company, or the Trust, as
         the case may be, has complied with all the agreements and satisfied all
         the conditions on its part to be performed or satisfied at or prior to
         the Closing Date;

              (ii) To their knowledge, no stop order suspending the
         effectiveness of the Registration Statement has been issued and no
         proceedings for that purpose have been instituted or as the case may
         be, threatened; and

              (iii) Since the date of the most recent financial statements
         included in the Prospectus (exclusive of any supplement thereto), there
         has been no Material Adverse Effect on the condition (financial or
         otherwise), earnings, business or properties of the Company and its
         subsidiaries, taken as a whole, whether or not arising from
         transactions in the ordinary course of business, except as set forth in

         thereto).

          (h) Deloitte & Touche LLP shall have furnished to the Representatives

         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

                                       23
   24
         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 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

              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

                   (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

                                       24
   25
              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

              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 subsidiaries and purchases in
              the open market in anticipation thereof) or any increase in
              short-term debt, or any decrease in consolidated common
              shareholders' equity of the Company and its consolidated
              subsidiaries (other than periodic dividends declared to

              preferred redeemable increased dividend equity securities of the
              Company), 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;

                   (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

                                       25
   26
              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

                   (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.

              (i) On the Closing Date, the Representatives shall have received
from Deloitte & Touche LLP a letter, dated as of the Closing Date, to the effect
that they reaffirm the statements made in the letter furnished pursuant to
subsection (i) of this Section, except that the specified date referred to shall
be a date not more than three business days prior to the Closing Date.

              (j) Subsequent to the Execution Time or, if earlier, the dates as
of which information is given in the Registration Statement (exclusive of any
amendment thereof) and the Prospectus (exclusive of any supplement thereto),
there shall not have been (i) any change or decrease specified in the letter or
letters referred to in paragraph (i) of this Section 6 or (ii) any change, or
any development involving a prospective change, in or affecting the condition
(financial or otherwise), earnings, business or properties of the Company and
its subsidiaries, taken as a whole, whether or not arising from transactions in
the ordinary course of business, except as set forth in or contemplated in the
Prospectus (exclusive of any supplement thereto) the effect of which, in any
case referred to in clause (i) or (ii) above, is, in the reasonable judgment of
the Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the Securities as
contemplated by the Registration Statement (exclusive of any amendment thereof)
and the Prospectus (exclusive of any supplement thereto).

                                       26

delivered to the Underwriters a letter, dated the Closing Date, from such
nationally recognized statistical rating agency, or other evidence satisfactory
to the Underwriters, confirming that the Preferred Securities have ratings
consistent with the foregoing; and (i) there shall not have occurred any
decrease in the ratings of any of the securities of the Company or of the
Preferred Securities by any "nationally recognized statistical rating
organization" (as defined for purposes of Rule 436(g) under the 1933 Act
Regulations) and (ii) such organizations shall not have publicly announced that
it has under surveillance or review, with possible negative implications, its
rating of any of the securities of the Company or of the Preferred Securities.

              (m) Prior to the Closing Date, the Company shall have furnished to
the Representatives such further information, certificates and documents as the
Representatives may reasonably request.

              If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Underwriters, this Agreement and all obligations of the Underwriters hereunder
may be canceled at, or at any time prior to, the Closing Date by the
Representatives. Notice of such cancellation shall be given to the Company in
writing or by telephone or facsimile confirmed in writing.

              The documents required to be delivered by this Section 6 shall be
delivered at the office of LeBoeuf, Lamb, Greene & MacRae, L.L.P., counsel for
the Underwriters, at 125 West 55th Street, New York, New York 10019, on the
Closing Date.

         7.   Reimbursement of Underwriters' Expenses. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied
or because of any refusal, inability or failure on the part of the Company to
perform any agreement herein or comply with any provision hereof other than by
reason of a default by any of the Underwriters, the Company will reimburse the
Underwriters severally through Salomon Smith Barney Inc. on demand for all
reasonable out-of-pocket expenses (including reasonable fees and disbursements
of counsel) that shall have been incurred by them in connection with the
proposed purchase and sale of the Securities.

         8.   Indemnification and Contribution. (a) The Offerors agree to
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to which they or any
of them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the registration statement for the registration of
the Securities as originally filed or in any amendment thereof, or in any
Preliminary Prospectus or the Prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party, as incurred, for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
Offerors will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished to
the Offerors by or on behalf of any Underwriter through the Representatives
specifically for inclusion therein. This indemnity agreement will be in addition
to any liability which the Offerors may otherwise have.

              (b) Each Underwriter severally and not jointly agrees to
indemnify and hold harmless the Offerors, each of their respective directors,
trustees, officers and agents, and each person who controls the Offerors within
the meaning of either the Act or the Exchange Act, to the same extent as the
foregoing indemnity from the Offerors to each Underwriter, but only with
reference to written information relating to such Underwriter furnished to the
Offerors by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity. This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have. The Offerors acknowledge that the statements
set forth in the last paragraph of the cover page regarding delivery of the
Securities and, under the heading "Underwriting", (i) the sentences related to
concessions and reallowances and (ii) the paragraph related to stabilization,
syndicate covering transactions and penalty bids in any Preliminary Prospectus
and the Prospectus constitute the only information furnished in writing by or on
behalf of the several Underwriters for inclusion in any Preliminary Prospectus
or the Prospectus.

              (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless

                                       28
   29
and to the extent it did not otherwise learn of such action and such failure
results in the forfeiture by the indemnifying party of substantial rights and
defenses and (ii) will not, in any event, relieve the indemnifying party from
any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a) or (b) above. The indemnifying party shall
be entitled to appoint counsel of the indemnifying party's choice at the
indemnifying party's expense to represent the indemnified party in any action
for which indemnification is sought (in which case the indemnifying party shall
not thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be satisfactory to the indemnified
party. Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party and which
conflict with the defenses available to the indemnified party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding 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) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Offerors and the Underwriters severally
agree to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which the Offerors
and one or more of the Underwriters may be subject in such proportion as is
appropriate to reflect the relative benefits received by the Offerors on the one
hand and by the Underwriters on the other from the offering of the Securities;
provided, however, that in no case shall any Underwriter (except as may be
provided in any agreement among underwriters relating to the offering of the
Securities) be responsible for any amount in excess of the underwriting discount

                                       29
   30
or commission applicable to the Securities purchased by such Underwriter
hereunder. If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Offerors and the Underwriters severally shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Offerors on the one hand
and of the Underwriters on the other in connection with the statements or
omissions which resulted in such Losses as well as any other relevant equitable
considerations. Benefits received by the Offerors shall be deemed to be equal to
the total net proceeds from the offering (before deducting expenses) received by
it, and benefits received by the Underwriters shall be deemed to be equal to the
total underwriting discounts and commissions, in each case as set forth on the
cover page of the Prospectus. Relative fault shall be determined by reference
to, among other things, whether any untrue or any alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information provided by the Offerors on the one hand or the
Underwriters on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The Offerors and the Underwriters agree that it
would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 8, each person who controls an Underwriter within the meaning of
either the Act or the Exchange Act and each director, officer, employee and
agent of an Underwriter shall have the same rights to contribution as such
Underwriter, and each person who controls the Offerors within the meaning of
either the Act or the Exchange Act and each director, trustee, officer, employee
and agent of the Offerors shall have the same rights to contribution as the
Offerors, subject in each case to the applicable terms and conditions of this
paragraph (d).

         9.   Default by an Underwriter. If any one or more Underwriters shall
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of Securities set
forth opposite their names in Schedule I hereto bears to the aggregate amount of
Securities set forth opposite the names of all the remaining Underwriters) the
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase; provided, however, that in the event that the aggregate amount of
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase shall exceed 10% of the aggregate amount of Securities set forth in
Schedule I hereto, the remaining Underwriters shall have the right to purchase
all, but shall not be under any obligation to purchase any, of the Securities,
and if such nondefaulting Underwriters do not purchase all the Securities, this
Agreement will terminate without liability to any nondefaulting Underwriter or
the Offerors. In the event of a

                                       30
   31
default by any Underwriter as set forth in this Section 9, the Closing Date
shall be postponed for such period, not exceeding five Business Days, as the
Representatives shall determine in order that the required changes in the
Registration Statement and the Prospectus or in any other documents or
arrangements may be effected. Nothing contained in this Agreement shall relieve
any defaulting Underwriter of its liability, if any, to the Offerors and any
nondefaulting Underwriter for damages occasioned by its default hereunder.

         10.  Termination. This Agreement shall be subject to termination in the
absolute discretion of the Representatives, by notice given to the Offerors
prior to delivery of and payment for the Securities, if at any time prior to
such time (i) trading in the Securities of the Company shall have been suspended
by the Commission or the New York Stock Exchange or trading in securities
generally on the New York Stock Exchange shall have been suspended or limited or
minimum prices shall have been established on such Exchange, (ii) a banking
moratorium shall have been declared either by Federal, New York or Michigan
authorities or (iii) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of a national emergency or war or
other calamity or crisis the effect of which on financial markets is such as to
make it, in the reasonable judgment of the Representatives, impractical or
inadvisable to proceed with the offering or delivery of the Securities as
contemplated by the Prospectus (exclusive of any supplement thereto).

         11.  Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Offerors or their respective officers and agents and of the Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of any Underwriter
or the Offerors or any of the officers, directors or controlling persons
referred to in Section 8 hereof, and will survive delivery of and payment for
the Securities. The provisions of Sections 7 and 8 hereof shall survive the
termination or cancellation of this Agreement.

         12.  Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representatives, will be mailed,
delivered or telefaxed to the Salomon Smith Barney Inc. General Counsel (fax
no.: (212) 816-7912 and confirmed to the General Counsel, Salomon Smith Barney

Senior Vice President and General Counsel.

         13.  Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the officers
and directors and controlling

                                       31
   32
persons referred to in Section 8 hereof, and no other person will have any right
or obligation hereunder.

         14.  Applicable Law. This Agreement will be governed by and 
construed in accordance with the laws of the State of New York applicable to 
contracts made and to be performed within the State of New York.

         15.  Counterparts. This Agreement may be signed in one or more
counterparts, each of which shall constitute an original and all of which
together shall constitute one and the same agreement.

         16.  Headings. The section headings used herein are for convenience
