(1) If the Company has elected not to rely upon Rule 430A of the 1933 Act Regulations, the initial public offering price per Security and the purchase price per Security to be paid by the several Underwriters for the Securities have each been determined and set forth in the Pricing Agreement, dated the date hereof, and any necessary amendments to the Registration Statement and the Prospectus will be filed before the Registration Statement becomes effective. (2) If the Company has elected to rely upon Rule 430A of the 1933 Act Regulations, the purchase price per Security to be paid by the several Underwriters shall be an amount equal to the initial public offering price per Security, less an amount per Security to be determined by agreement between the Underwriters and the Company. The initial public offering price per Security shall be a fixed price to be determined by agreement between the Underwriters and the Company. The initial public offering price and the purchase price, when so determined, shall be set forth in the Pricing Agreement. In the event that such prices have not been agreed upon and the Pricing Agreement has not been executed and delivered by all parties thereto by the close of business on the fourth business day following the date of this Agreement, this Agreement shall terminate forthwith, without liability of any party to any other party, unless otherwise agreed to by the Company and the Underwriters.

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.

(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.

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.

(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.

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.

(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.

(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;

(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; -29- 30 (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 consolidated common shareholders' equity (other than quarterly 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;

(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. -30- 31 (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.

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 to any other party except as provided in Section 4. -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 -36- 37 duly given if mailed or transmitted by any standard form of telecommunication.
