Income PRIDES(SM)) with a Stated Amount of $50 comprised of (a) a stock
purchase contract (the "Purchase Contract") under which (i) the holder will

"Delaware Trustee" and, together with the Institutional Trustee and the Regular
Trustees, the "Trustees"), and the holders from time to time of undivided
beneficial interests in the assets of the Trust.  The Junior Subordinated
Debentures will be issued pursuant to the Subordinated Debt Securities
Indenture, dated as of September 1, 1994 (the "Base Indenture"), between the

First Supplemental Indenture, dated April 17, 1996, the Second Supplemental
Indenture, dated July 24, 1996 and the Third Supplemental Indenture, dated
March 19, 1997 (the Base Indenture, as supplemented and amended, being referred

be used as defined in the Prospectus.

         Prior to the purchase and public offering of the Securities by the
several Underwriters, the Offerors 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 communication
between the Offerors 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 the Trust, MCN Financing II and MCN Financing IV

effective amendment no. 1 thereto covering the registration of securities of
the Company and the MCN Trusts, including the Securities and the Purchase
Contracts and Preferred Securities 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 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 any, deemed to be a part
thereof pursuant to Rule 430A(b) of the 1933 Act 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 Offerors file
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 Offerors elect to rely upon Rule 434 of the 1933 Act Regulations, then all
references to "Prospectus" shall be deemed to include the final or preliminary
prospectus and the applicable term sheet or abbreviated term sheet (the "Term
Sheet"), as 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 Underwriting Agreement to the date of the Prospectus shall
mean the date of the Term Sheet. A "preliminary prospectus" shall be deemed to
refer to any prospectus used before the registration statement became effective
and any prospectus that omitted, as applicable, the Rule 430A Information, the
Rule 434 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
prospectus, the Prospectus or any Term Sheet or any amendment or supplement to
any of the foregoing shall be deemed to include the





                                      -4-

electronically transmitted copy thereof filed with the Commission pursuant to
its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

         All references in this Agreement to financial statements and schedules
and other information which is "contained," "included" or "stated" in the
Registration Statement, any preliminary prospectus or the Prospectus (or other
references of like import) shall be deemed to mean and include all such
financial statements and schedules and other information which is incorporated
by reference in the Registration Statement, any preliminary prospectus or the
Prospectus, as the case may be; and all references in this Agreement to
amendments or supplements to the Registration Statement, any preliminary
prospectus or the Prospectus shall be deemed to mean and include the filing of
any document under the 1934 Act which is incorporated by reference in the
Registration Statement, such preliminary prospectus or the Prospectus, as the
case may be.

         The Offerors understand that the Underwriters propose to make a public
offering of the Securities as soon as the Representatives deem advisable after
the Pricing Agreement has been executed and delivered and the Declaration, the
Indenture and the Preferred Securities Guarantee Agreement have been qualified
under the Trust Indenture Act of 1939, as amended (the "1939 Act").

         SECTION 1.  Representations and Warranties.

         (a)  The Offerors represent and warrant to each Underwriter as of the
date hereof and as of the date of the Pricing Agreement (such later date being
hereinafter referred to as the "Representation Date") that:

                 (i)  No stop order suspending the effectiveness of the
Registration Statement has been issued and no proceeding for that purpose has
been initiated or, to the knowledge of the Offerors, threatened by the
Commission.

                 (ii)  The Company and the MCN Trusts meet, and at the
respective times of the commencement and consummation of the offering of the
Securities will 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.  At the respective times the

each Representation Date, the Registration Statement, any Rule 462 Registration
Statement and any amendments or supplements thereto complied and will comply in
all material respects with the requirements of the 1933 Act and the 1933 Act
Regulations and the 1939 Act and the rules and





                                      -5-

to state a material fact required to be stated therein or necessary to make the
statements therein not misleading.  At the date of the Prospectus and at the
Closing Time (as defined herein), the Prospectus and any amendments and
supplements thereto 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.  If the Offerors elect to rely upon Rule 434 of the 1933
Act Regulations, the Offerors will comply with the requirements of Rule 434.
Notwithstanding the foregoing, the representations and warranties in this
subsection shall not apply to (A) statements in or omissions from the
Registration Statement or the Prospectus made in reliance upon and in
conformity with information furnished to the Offerors in writing by any
Underwriter through Merrill Lynch expressly for use in the Registration
Statement or the Prospectus or (B) the part of the Registration Statement which
shall constitute the Statement of Eligibility (Form T-1) under the 1939 Act.

                 Each preliminary prospectus and prospectus filed as part of
the Registration Statement as originally filed or as part of any amendment
thereto, or filed pursuant to Rule 424 under the 1933 Act, complied as so filed
in all material respects with the 1933 Act Regulations and, if applicable, each
preliminary prospectus and the Prospectus delivered to the Underwriters for use
in connection with the offering of the Securities will, at the time of such
delivery, be identical to the electronically transmitted copies thereof filed
with the Commission pursuant to EDGAR, except to the extent permitted by
Regulation S-T.

                 (iii)  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





                                      -6-
   7

warranty shall not apply to any statements or omissions made in reliance upon
and in conformity with information furnished in writing to the Offerors 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 and the Prospectus are independent public accountants as
required by the 1933 Act and the 1933 Act Regulations.

                 (v)  The financial statements of the Company 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.  Such
financial statements have been prepared in conformity with generally accepted
accounting principles ("GAAP") applied on a consistent basis throughout the
periods involved.  The supporting schedules, if any, included or incorporated
by reference in the Registration Statement and the Prospectus present fairly in
accordance with GAAP 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 and the Prospectus.

                 (vi)  Since the respective dates as of which information is
given in the Registration Statement and the Prospectus, and except as otherwise
stated therein, (A) there has been no material adverse change and no
development which could reasonably be expected to result in a 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 (a "Material Adverse Effect"), whether or not arising in the
ordinary course of business, (B) there have been no transactions entered into
by the Company or any of its subsidiaries, other than those arising in the
ordinary course of business, which are material with respect to the Company and
its subsidiaries, considered as one enterprise, (C) except for regular
dividends on the Common Stock in amounts per share that are consistent with
past practice or the applicable charter document or supplement thereto,
respectively, there has been no dividend or distribution of any kind declared,
paid or made by the Company on any class of its capital stock.

by the Company and, at the Closing Time, when validly executed and delivered by
the Company and assuming due authorization, execution and delivery of the
Purchase Contract Agreement by the Purchase Contract Agent, will constitute a
legal, 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, insolvency, reorganization, moratorium or
other similar laws affecting creditors' rights generally or by general

any of its subsidiaries exists or, to the knowledge of the Company, is
imminent; and the Company is not aware of any existing or imminent labor

                 (xxv)  The Company and its subsidiaries have good and
marketable title to all material real and personal property owned by them, in
each case free and clear of all liens, encumbrances and defects except such as

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

                 (xxxi)  No "forward looking statement" (as defined in Rule 175
under the 1933 Act) contained in the Registration Statement, any preliminary
prospectus or the Prospectus was made or reaffirmed without a reasonable basis
or was disclosed other than in good faith.

                 (b)  Any certificate signed by any officer of the Company or a
Trustee of the Trust and delivered to the Representatives or to counsel for the
Underwriters shall be deemed a representation and warranty by the Company or
the Trust, as the case may be, to each Underwriter as to the matters covered
thereby.

         SECTION 2.  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
Offerors agree to sell to each Underwriter, and each Underwriter severally and
not jointly, agrees to purchase from the Offerors, at the price per security
set forth in the Pricing Agreement, the number of Initial Securities set forth
in Schedule A hereto opposite the name of such Underwriter, plus any additional
number of Initial Securities which such Underwriter may become obligated to
purchase pursuant to the provisions of Section 10 hereof.

                 (1)  If the Offerors have 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 Offerors have 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 Offerors.  The initial public offering price
per Security shall be a fixed price to be determined by agreement between the
Underwriters and the Offerors.  The initial





                                      -14-
   15

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 Offerors and the Underwriters.

         (b)     In addition, on the basis of the representations and
warranties herein contained and subject to the terms and conditions herein set
forth, the Offerors hereby grant to the Underwriters, severally and not
jointly, the right to purchase at their election up to 345,000 Option
Securities 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 Offerors
have elected not to rely upon Rule 430A under the 1933 Act Regulations, or (ii)
the Representation Date, if the Offerors have 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 Offerors setting forth the aggregate number
of additional Optional Securities to be purchased 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, unless otherwise agreed upon by the
Underwriters and the Offerors.  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 purchase from the Company the same percentage of the
total number of Option Securities as such Underwriter is purchasing of the
Initial Securities as set forth in Schedule A hereto (subject in each case to
such adjustments as the Representatives in their discretion shall make to
eliminate any fractional Option Securities).

         (c)     The Preferred Securities underlying the Securities 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 of the Preferred Securities 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 and the
Option Securities (if the option provided for in Section 2(b) hereof shall have
been exercised on or before the first business





                                      -15-
   16

day prior to the Closing Time) shall be made at the offices of the Underwriters
in New York, against the delivery to the Collateral Agent of the Preferred
Securities relating to such Securities by such Underwriters or on their behalf,
and payment of the purchase price for such Securities shall be made at the
offices of LeBoeuf, Lamb, Greene & MacRae, L.L.P, 125 West 55th Street, New
York, New York  10019 or at such other place as shall be agreed upon by the
Underwriters and the Offerors, at 10:00 a.m. (New York time) on the third
business day after the date the Registration Statement becomes effective (or,
if the Offerors have 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 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 Offerors (such time
and date of payment and delivery being referred to herein as the "Closing
Time").  Payment for the Securities purchased by the Underwriters shall be made
by wire transfer of immediately available funds, payable to the Company,
against delivery to the respective accounts of the Underwriters of the
Securities to be purchased by it.  Delivery of, and payment for, the Securities
shall be made through the facilities of the Depository Trust Company.  In
addition, if the Underwriters purchase any or all of the Option Securities,
payment of the purchase price 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 Offerors, on each Date of Delivery as specified in the
relevant notice from the Underwriters to the Offerors.

                 Certificates for the Initial Securities and the Option
Securities, if any, 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. Merrill
Lynch, individually and not as representative of the Underwriters, may (but not
shall be obligated to) make payment of the purchase price for the Securities,
if any, to be purchased by any Underwriter whose funds have not been received
by the Closing Time, or the Date of Delivery, as the case may be, but such
payment shall not relieve such Underwriter from its obligations hereunder.  The
certificates for the Initial Securities and the Option Securities, if any, will
be made available for examination 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.

         (e)     If settlement for the Option Securities occurs after the
Closing Time, the Offerors will deliver to the Underwriters on the relevant
Date of Delivery, and the obligations of the Underwriters to purchase the
Option Securities shall be





                                      -16-
   17

conditioned upon the receipt of, supplemental opinions, certificates and
letters confirming as of such date the opinions, certificates and letters
delivered at the Closing Time pursuant to Section 5(k) hereof.

         SECTION 3.  Covenants of the Offerors.  The Offerors agree with each
Underwriter as follows:

         (a)  Promptly following the execution of this Agreement, the Offerors
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 Offerors will promptly advise the
Underwriters when such filing has been made.  Prior to the filing, the Offerors
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 Offerors 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) the receipt of any comments from the Commission, (iii) of any
request by the Commission for any amendment to the Registration Statement or
any amendment or supplement to the Prospectus or for additional information,
(iv) 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 (v) 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 Offerors will make every reasonable
effort to prevent the issuance of any stop order and, if any stop order is
issued, to obtain the lifting thereof at the earliest possible moment.

         (c)  The Offerors 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, 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,





                                      -17-
   18

Term Sheet, amendment, supplement or revision to which the Underwriters or
counsel for the Underwriters shall object.

         (d)  The Company will deliver to Merrill Lynch and counsel for the
Underwriters, without charge, signed copies of the Registration Statement as
originally filed and of each amendment thereto (including exhibits filed
therewith or incorporated by reference therein and documents incorporated or
deemed to be incorporated by reference therein) and signed copies of all
consents and certificates of experts, and will also deliver to Merrill Lynch,
without charge, a conformed copy of the Registration Statement as originally
filed and of each amendment thereto (without exhibits) for each of the
Underwriters.  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,
without charge, 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
transmitted copies thereof filed with the Commission pursuant to EDGAR, except
to the extent permitted by Regulation S-T.

         (f)  The Offerors will comply with the 1933 Act and the 1933 Act
Regulations and the 1934 Act and the 1934 Act Regulations so as to permit the
completion of the distribution of the Securities as contemplated in this
Agreement and in the Registration Statement and the Prospectus.  If at any time
when the Prospectus is required by the 1933 Act or the 1934 Act to be delivered
in connection with sales of the Securities, any event shall occur or condition
shall exist as a result of which it is necessary, in the opinion of counsel for
the Underwriters or for the Offerors, to amend the Registration Statement in
order that the Registration Statement 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 or to amend or
supplement the Prospectus in order that 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 not misleading in the light of the
circumstances existing at the time it is delivered to a purchaser, or if it
shall be necessary, in the opinion of such counsel, at any such time to amend
the Registration Statement or





                                      -18-
   19

amend or supplement the Prospectus in order to comply with the requirements of
the 1933 Act or the 1933 Act Regulations, the Offerors will promptly prepare
and file with the Commission, subject to Section 3(c), such amendment or
supplement as may be necessary to correct such statement or omission or to make
the Registration Statement or the Prospectus comply with such requirements, and
the Offerors will furnish to the Underwriters, without charge, such number of
copies of such amendment or supplement as the Underwriters may reasonably
request.

         (g)  The Offerors will use their best efforts, in cooperation with the
Underwriters, to qualify the Securities for offering and sale under the
applicable securities laws of such states and other jurisdictions (domestic or
foreign) as Merrill Lynch 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 or subject itself to taxation in respect of
doing business in any jurisdiction in which it is not otherwise so subject.  In
each jurisdiction in which the Securities have been so qualified, the Offerors
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 Offerors 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.





                                      -19-
   20

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

         (l)  The Offerors, 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 Offerors will use their best efforts to effect the listing of
the Income PRIDES 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 90 days from the date of the Pricing
Agreement, neither the Trust nor the Company will, 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, Preferred Securities or
Common Stock or any security convertible into or exchangeable or exercisable
for Securities, Purchase Contracts, Preferred Securities, Common Stock or the
Junior Subordinated Debentures, or any equity securities substantially similar
to the Securities, Preferred Securities, Purchase Contracts or Common Stock or
any debt securities substantially similar to the Junior Subordinated
Debentures; provided, however, that such restriction shall not affect the
ability of the Offerors 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,
including the Preferred Securities, and the Junior Subordinated Debentures
issued pursuant to this Agreement.

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





                                      -20-
   21

         (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 and shall take all actions necessary to
keep effective the Registration Statement with respect to the Shares.

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

         SECTION 4.  Payment of Expenses.  The Company will pay all expenses
incident to the performance of its obligations under this Agreement, the

         believe that any of such documents, when such





                                      -24-
   25

         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 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.

         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

                                      -28-
   29

         the business of the Company and its subsidiaries, considered as one
         enterprise; all such licenses, franchises, permits, certificates,
         authorizations, approvals, consents and orders are in full force and
         effect and contain no unduly burdensome provisions that would
         interfere with the conduct of the business of the Company and its
         subsidiaries, considered as one enterprise and, except as otherwise
         set forth in the Registration Statement or the Prospectus, there are
         no legal or governmental proceedings pending or threatened that would

         thereunder.

         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 the notes
         thereto, the financial schedules and any other financial data included
         or incorporated by reference therein, as to which counsel need express
         no opinion), at the time 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 the notes thereto, the financial
         schedules, and any other financial data included or incorporated by
         reference therein, as to which counsel need express no opinion), at
         the 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 the Closing
         Time, included (or includes) an untrue statement of a material fact or
         omitted or omits to state a material fact necessary in order to make
         the statements therein, in the light of the circumstances under which
         they were made, not misleading.

                 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





                                      -29-

Delaware law, upon the opinion of Skadden, Arps, Slate, Meagher & Flom, special

Skadden, Arps, Slate, Meagher & Flom LLP, special counsel to the Offerors, in
form and substance satisfactory to counsel for the Underwriters and subject to

         amendment or supplement thereto (other than the financial statements
         and the notes thereto, the financial schedules and any other financial

                              (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 enforceable against the Company in
         accordance with its terms, except as may be limited by the Bankruptcy
         Exceptions; provided, however, that based on a review of applicable
         case law, 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
         3.15 and 5.8 of the Purchase Contract Agreement and Section 4.3 of the
         Pledge Agreement that require termination of the Purchase Contracts
         and release of the Collateral Agent's security interest in the
         Preferred Securities or the Treasury Securities; 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)   When the Securities are issued in
         accordance with the terms of the Purchase Contract Agreement and
         delivered against payment therefor, the Securities will entitle the
         holders thereof to the rights specified in the Purchase Contract
         Agreement.

                              (vi)   For purposes of the opinions expressed
         therein, such counsel has assumed that (1) the Pledge Agreement has
         been duly authorized, executed and delivered by the Purchase Contract
         Agent on behalf of each of the holders of the Securities from time to
         time, (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 of the Securities 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 of the Securities from time to time, and (5) the
         Purchase Contract Agent and each holder of Securities has sufficient
         rights in the Preferred Securities or the Treasury Securities, as the
         case may be, for the security interest of the Collateral Agent for the
         benefit of the Company to attach.

                 For purposes of such counsel's opinion:  (i) "UCC" means the
Uniform Commercial Code as in effect on the date





                                      -31-
   32

thereof in the State of New York; (ii) "Federal Book-Entry Regulations" means
the United States Department of Treasury regulations governing the transfer and
pledge of marketable Treasury Securities maintained in the form of entries in
the records of the Federal Reserve Banks and set forth in 61 Fed. Reg. 43,626
(1996) (to be codified at 31 C.F.R. Part 357), including the 1994 Official Text
of the Uniform Commercial Code, Revised Article 8, Investment Securities (with
Conforming and Miscellaneous Amendments to Articles 1, 3, 4, 5, 9 and 10)
adopted by the American Law Institute and National Conference of Commissioners
On Uniform State Laws and approved by the American Bar Association on February
14, 1995, which is incorporated by reference pursuant to 61 Fed. Reg. 43,626
(1996) (to be codified at 31 C.F.R. Section  357.2; (iii) "Securities
Intermediary" means The Chase Manhattan Bank acting solely in its capacity as a
"securities intermediary" as defined in the Federal Book-Entry Regulations;
(iv) "Security Entitlements" means "security entitlements" as defined in the
Federal Book-Entry Regulations; and (v) "Collateral Account" means account
number MB9198919 maintained by the Securities Intermediary in the name "The
First National Bank of Chicago as Purchase Contract Agent on behalf of the
holders of certain securities of MCN Corporation, subject to the security
interest of The Chase Manhattan Bank as Collateral Agent for the benefit of MCN
Corporation as pledgee" pursuant to the Pledge Agreement, dated as of March 25,
1997, among the Securities Intermediary, the Purchase Contract Agent and the
Company (the "Pledge Agreement") and (vi) "Financial Intermediary" means The
Chase Manhattan Bank acting solely in its capacity as a "financial
intermediary" as defined in Section 8-313(4) of the UCC.

                 (A)      The "transfer" of the Preferred Securities together
with the Pledge Agreement will be effective to create in favor of the
Collateral Agent for the benefit of the Company a valid and perfected security
interest in the Preferred Securities to secure the obligations of the holders
under the Purchase Contracts.  Transfer of the Preferred Securities will occur
upon the latest of (a) the delivery of the Preferred Securities to the
Financial Intermediary indorsed to the Financial Intermediary or in blank, (b)
the sending of a confirmation by the Financial Intermediary of the purchase by
the Collateral Agent for the benefit of the Company of such Preferred
Securities and (c) the identification by book-entry of the Preferred Securities
to the Collateral Account.

                 (B)      Such counsel notes that although the Federal
Book-Entry Regulations contain express provisions identifying the law governing
perfection and priority of security interests in security entitlements, they do
not contain express provisions identifying the law governing validity and
attachment of such security interests.  Such counsel further notes that the
parties have chosen the laws of the State of New York to govern the Pledge
Agreement and that the UCC does not contain any provisions





                                      -32-
   33

with respect to the creation of a security interest in collateral constituting
a "security entitlement."  The UCC, however, does contain provisions for
creation of a security interest in collateral constituting either a "general
intangible" or a "security" (each as defined in the UCC).  If and to the extent
(i) the Federal Book-entry Regulations do not preempt the choice of New York
law with respect to the validity and attachment of the security interest in the
Treasury Security Entitlements (as defined herein), (ii) under New York law a
security interest in a "security entitlement" with respect to a book-entry
security issued by the U.S. Treasury would be created in the same manner as a
security interest in a "general intangible" (as defined in the UCC), such
counsel is of the opinion that the provisions of the Pledge Agreement are
effective to create a valid security interest in favor of the Company, to
secure the obligations of the holders of the Growth PRIDES under the Purchase
Contracts comprising a part of such Growth PRIDES, in each such holder's rights
in all "security entitlements" with respect to book- entry securities issued by
the United States Treasury and credited to the Collateral Account (such
security entitlements, the "Treasury Security Entitlements").  Alternatively,
if and to the extent (i) the Federal Book-Entry Regulations do not preempt the
choice of New York law with respect to the validity and attachment of the
security interest in the Treasury Security Entitlements, and (ii) under New
York law a security interest in a "security entitlement" with respect to a
book-entry security issued by the U.S. Treasury would be created in the same
manner as a security interest in a "security" (as defined in the UCC), such
counsel is of the opinion that the provisions of the Pledge Agreement together
with the "transfer" (within the meaning of Section 8-313 of the UCC) of the
Treasury Security Entitlements to the Collateral Agent will be effective to
create a valid security interest in favor of the Collateral Agent for the
benefit of the Company, to secure the obligations of the holders of the Growth
PRIDES under the Purchase Contracts, in such holders' rights in all Treasury
Security Entitlements.  Assuming that the Securities Intermediary satisfies the
requirements of Section 8-313(d)(iii) of the UCC (as to which such counsel
expresses no opinion), "transfer" of the Treasury Securities Entitlements will
occur upon the later to occur of (1) the sending of a confirmation by the
Securities Intermediary to the Collateral Agent for the benefit of the Company
of the purchase by the Collateral Agent of the Treasury Securities Entitlements
and (2) the identification by book-entry by the Securities Intermediary of the
Treasury Securities Entitlements as belonging to the Collateral Agent for the
benefit of the Company.

                 (C)      Upon the execution and delivery of the Pledge
Agreement and the establishment of the Collateral Account in accordance with
the terms of the Pledge Agreement, the security interest of the Company in the
Treasury Securities Entitlements will be perfected under the Federal Book-Entry
Regulations.

                             (vii)   Assuming the Preferred Securities
         Guarantee Agreement has been duly authorized, executed and delivered
         by the Company under Michigan law, it is a legal, valid and binding
         agreement 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.

                            (viii)   Assuming the Indenture has been duly
         authorized, executed and delivered by the Company under Michigan law
         and, assuming due authorization, execution, and delivery thereof by
         the Debt Trustee, it is a legal, 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, Declaration and Preferred
         Securities Agreement have been duly qualified under the 1939 Act.

                              (ix)   The Securities, the Common Securities, the
         Junior Subordinated Debentures, each of the Guarantees, the
         Declaration and each of the Guarantee Agreements conform in all
         material respects to the description thereof contained in the
         Prospectus.

                               (x)   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 by the Offerors to the
         Underwriters, or the issuance and sale of the Shares by the Company
         pursuant to such Purchase Contracts, or the performance by the Company
         and the Trust of their respective obligations under this Agreement,
         the Pricing Agreement, the Purchase Contracts, the Purchase Contract
         Agreement, the Pledge Agreement, the Indenture, the Junior
         Subordinated Debentures, the Preferred Securities Guarantee Agreement,
         the Preferred Securities Guarantee, the Declaration and the
         Securities, except such as has been obtained and made under the
         federal securities laws or such as may be required under state or
         foreign securities or Blue Sky laws.

                              (xi)  The issuance and sale of the Securities do 
         not contravene the Commodity Exchange Act or the regulations of the
         Commodity Futures Trading Commission.

         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 the notes
         thereto, the financial schedules, and any other financial data
         included





                                      -34-
   35

         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 the notes thereto, the financial
         schedules, and any other financial data included or incorporated by
         reference therein, as to which counsel need express no opinion), at
         the 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 the Closing
         Time, included (or includes) an untrue statement of a material fact or
         omitted or omits to state a material fact necessary in order to make
         the statements therein, in the light of the circumstances under which
         they were made, not misleading.

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

                               (i)   The Trust has been duly created and is
         validly existing in good standing as a business trust under the
         Delaware Act, and has the business trust power and authority to
         conduct its business as described in the Registration Statement and
         the Prospectus.

                              (ii)   Assuming that the Declaration has been
         duly authorized, executed and delivered by the Company, and assuming
         the due authorization, execution and delivery of the Declaration by
         Wilmington Trust Company and the Regular Trustees, the Declaration
         constitutes a legal, valid and binding obligation of the Company and
         is enforceable against the Company in accordance with its terms,
         except that to the extent enforceability thereof may be limited by the
         Bankruptcy Exceptions.

                             (iii)   Under the Delaware Act and the
         Declaration, the Trust has the power and authority to (i) execute and
         deliver, and to perform its obligations under, this Agreement and the
         Pricing Agreement and (ii) issue, and perform its obligations under,
         the Trust Securities.

                              (iv)   The execution and delivery by the Trust of
         this Agreement and the Pricing Agreement, and the performance by the
         Trust of its obligations hereunder and





                                      -35-
   36

         under the Pricing Agreement, have been duly authorized by all
         necessary action on the part of the Trust.

                               (v)   The Preferred Securities have been duly
         authorized by the Declaration and, when executed by the trust and the
         Institutional Trustee in accordance with the Declaration and delivered
         against payment therefor in accordance with the terms of this
         Agreement, will be validly issued and, subject to qualifications
         hereinafter expressed in subparagraph (vi), fully paid and
         nonassessable undivided beneficial interests in the assets of the
         Trust; the holders of the Preferred Securities, as beneficial owners
         of the Trust, will be entitled to the same limitation of personal
         liability extended to stockholders of private corporations for profit
         organized under the General Corporation Law of the State of Delaware;
         said counsel may note that the holders of the Preferred Securities may
         be obligated to make payments as set forth in the Declaration.

                              (vi)   The Common Securities have been duly

         authenticated in accordance with the terms of the Declaration, and
         delivered and paid for as set forth in the Registration Statement,

         of the Trust.

                             (vii)   Under the Delaware Act and the
         Declaration, the issuance of the Trust Securities is not subject to
         preemptive or other similar rights.

                            (viii)   None of the execution and delivery by the
         Trust of, or the performance by the Trust of its obligations under,
         this Agreement, the issuance and sale of the Preferred Securities by
         the Trust in accordance with the terms of this Agreement and the
         Pricing Agreement, or the consummation of the other transactions
         contemplated thereby, will contravene any provisions of applicable
         Delaware law or administrative regulations or the Certificate of Trust
         or the Declaration.

                              (ix)   This Agreement and the Pricing Agreement
         have been duly authorized, executed and delivered by the Trust.

                               (x)   No authorization, approval, consent,
         order, registration or qualification of or with any Delaware state
         governmental authority or agency is required for the entry into the
         Purchase Contracts underlying the Securities, the issuance and sale of
         the Securities -by the Offerors to the Underwriters, or the issuance

         Contracts, or the performance by the Company and the Trust of their
         respective obligations under this Agreement, the Pricing Agreement,
         the

         Agreement, the Indenture, the Junior Subordinated Debentures, the
         Preferred Securities Guarantee Agreement, the Preferred Securities
         Guarantee, the Declaration and the  Securities, except such as has
         been obtained and made under the federal securities laws or such as
         may be required under state or foreign securities or Blue Sky laws.

                 (4)  The favorable opinion, dated as of the Closing Time, of
Richards, Layton & Finger, counsel to Wilmington Trust Company, as
Institutional Trustee under the Declaration, and Guarantee Trustee under the
Preferred Securities Guarantee Agreement, in form and substance satisfactory to
counsel for the Underwriters, to the effect that:

                               (i)   Wilmington Trust Company is a Delaware
         banking corporation with trust powers, duly organized, validly
         existing and in good standing under the laws of the State of Delaware
         with all necessary power and authority to execute and deliver, and to
         carry out and 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 by the Guarantee Trustee of the Preferred
         Securities Guarantee 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 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





                                      -37-

                 (5)  The favorable opinion, dated as of the Closing Time, of
Ungaretti & Harris, counsel to The First National Bank of Chicago, as Purchase
Contract Agent, in form and substance satisfactory to counsel for the
Underwriters, to the effect that:

                          (i) The First National Bank of Chicago is duly
         incorporated and is validly existing as a banking corporation with
         trust powers under the laws of the United States with all necessary
         power and authority to execute, deliver and perform its obligations
         under the Purchase Contract Agreement and the Pledge Agreement.

                          (ii)    The execution, delivery and performance by
         the Purchase Contract Agent of the Purchase Contract Agreement and the
         Pledge Agreement, and the authentication and delivery of the
         Securities have been duly authorized by all necessary corporate action
         on the part of the Purchase Contract Agent.  The Purchase Contract
         Agreement and the Pledge Agreement have been duly executed and
         delivered by the Purchase Contract Agent, and constitute the legal,
         valid and binding obligations of the Purchase Contract Agent,
         enforceable against the Purchase Contract Agent in accordance with its
         terms, except to the extent that enforcement thereof may be limited by
         the Bankruptcy Exceptions.

                          (iii) the execution, delivery and performance of the
         Purchase Contract Agreement and the Pledge Agreement by the Purchase
         Contract Agent does not conflict with or constitute a breach of the
         charter or by-laws of the Purchase Contract Agent.

                          (iv) No consent, approval or authorization of, or
         registration with or notice to, any Illinois or federal governmental
         authority or agency is required for the execution, delivery or
         performance by the Purchase Contract Agent of the Purchase Contract
         Agreement and the Pledge Agreement.

                 (6)  The opinion of Skadden, Arps, Slate, Meagher & Flom LLP,
special tax counsel to the Offerors, generally to the effect that based upon
current law and the assumptions stated or referred to therein, under current
U.S. federal income tax law: (i) the Trust will be classified as a grantor
trust and not as an association taxable as a corporation; (ii) the Junior
Subordinated Debentures will be classified as indebtedness of the Company, and
(iii)  The discussion set forth in the Prospectus under the headings "Risk
Factors - Proposed Tax Legislation" and "Certain Federal Income Tax
Consequences" is a fair and accurate summary of the matters addressed therein.
The opinion expressed





                                      -38-
   39

pursuant to clause (iii) 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 certificates of officers of the
Company and the Trust and other documents deemed necessary for such opinion.

matters as the Representatives may reasonably 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 its opinion, LeBoeuf,
Lamb, Greene & MacRae, L.L.P. may rely as to certain matters of Michigan and
Delaware law upon the opinions of Daniel L. Schiffer, Esq. and Skadden, Arps,
Slate, Meagher & Flom LLP, special Delaware counsel for the Offerors, which
shall be delivered in accordance with Section 5(b)(1) and 5(b)(3) hereof.

Pennsylvania counsel for the Underwriters, and (ii) Dickinson, Wright, Moon,
Van Dusen & Freeman, special Michigan counsel for the Underwriters, in form and
substance satisfactory to the Underwriters, with respect to the applicability
of the "bucket shop" laws of such states.

         (c)  Between the date of this Agreement and prior to the Closing Time,
no material adverse change shall have occurred in the condition, financial or
otherwise, or in the earnings, business affairs or business prospects of the

         Quarterly Reports on Form 10-Q incorporated by reference in the

                 substantially consistent with that of the audited consolidated

         statement or omission, provided, that (subject to Section 6(d) below)
         any such settlement is effected with the written consent of the
         Offerors; and

                             (iii)         against any and all expense
         whatsoever, as incurred (including, 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
Offerors by any Underwriter through Merrill Lynch expressly for use in the
Registration Statement (or any amendment thereto), including the Rule 430A
Information and the Rule 434 Information deemed to be a part thereof, if
applicable, or any preliminary prospectus or the Prospectus (or any amendment
or 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, the Trust and each of its





                                      -46-
   47

Trustees 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),
including the Rule 430A Information and the Rule 434 Information deemed to be a
part thereof, if applicable, 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 Offerors 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 hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which
it may have otherwise than on account of this indemnity agreement.  In the case
of parties indemnified pursuant to Section 6(a) above, counsel to the
indemnified parties shall be selected by Merrill Lynch, and, in the case of
parties indemnified pursuant to Section 6(b) above, counsel to the indemnified
parties shall be selected by the Offerors.  An indemnifying party may
participate at its own expense in the defense of any such action; provided,
however, that counsel to the indemnifying party shall not (except with the
consent of the indemnified party) also be counsel to the indemnified party.  In
no event shall the indemnifying parties be liable for fees and expenses of more
than one counsel (in addition to any local counsel) separate from their own
counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.  No indemnifying party shall,
without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 6 or Section
7 hereof (whether or not the indemnified parties are actual or potential
parties thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act by
or on behalf of any indemnified party.





                                      -47-
   48

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

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

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

         The relative fault of the Offerors, on the one hand, and the
Underwriters, on the other hand, shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Offerors or by the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.





                                      -48-
   49

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

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

         No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the 1933 Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

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

         SECTION 8.  Representations, Warranties and Agreements to Survive
Delivery.  All representations, warranties and agreements contained in this
Agreement and the Pricing Agreement, or contained in certificates of officers
of the Company or trustees of the Trust 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





                                      -49-
   50

on behalf of the Company, and shall survive delivery of and payment for 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 the Closing Time, if (i) there has been,
since the date of this Agreement or since the respective dates as of which
information is given in the Registration Statement, any material adverse change
or any development which could reasonably be expected to result in a
prospective material adverse change, financial or otherwise, or in the
earnings, business affairs or business prospects of the Company and its
subsidiaries considered as one enterprise, whether or not arising in the
ordinary course of business, or (ii) there has occurred any material adverse
change in the financial markets in the United States or any outbreak of
hostilities or escalation of hostilities or other calamity or crisis, or any
change or development involving a prospective change in national or
international political, financial or economic conditions the effect of which
is such as to make it, in the judgment of the 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, the
New York Stock Exchange or in the over-the-counter market has been suspended or
limited, or minimum or maximum prices for trading have been fixed, or maximum
ranges for prices for securities have been required, by either of said
exchanges or by such system or by order of the Commission, NASD or any other
governmental authority, or (iv) if a banking moratorium has been declared by
either Federal, New York or Michigan authorities.

         (b)  If this Agreement and the Pricing Agreement are terminated
pursuant to this Section 9, such termination shall be without liability of any
party to any other party except as provided in Section 4, and provided,
further, that Sections 1, 6 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, as the case may be, to
purchase the Initial Securities which it or they are obligated to purchase
under this Agreement and the Pricing Agreement (the "Defaulted Securities"),
Merrill Lynch 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 purchase all, but not less than all, of the Defaulted
Securities in such amounts as may be agreed upon and upon the terms herein set
forth; if, however, Merrill





                                      -50-
   51

Lynch shall not have completed such arrangements within such 24-hour period,
then:

                 (a)  if the number or aggregate principal amount, as the case
may be, of Defaulted Securities does not exceed 10% of the total number or
aggregate principal amount, as the case may be, of Initial Securities, the
non-defaulting Underwriters shall be obligated, severally and not jointly, to
purchase the full amount thereof in the proportions that their respective
underwriting obligations hereunder bear to the underwriting obligations of all
non-defaulting Underwriters, or

                 (b)  if the number or aggregate principal amount, as the case
may be, of Defaulted Securities exceeds 10% of the total number or aggregate
principal amount, as the case may be, of the Initial Securities to be purchased
on such date, this Agreement shall terminate without liability on the part of
any non-defaulting Underwriter.

                 No action taken pursuant to this Section 10 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 Merrill Lynch 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
the 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 duly given if mailed or
transmitted by any standard form of telecommunication.  Notices to the
Underwriters shall be directed to c/o Merrill Lynch at Merrill Lynch World

         SECTION 12.  Parties.  This Agreement and the Pricing Agreement shall
each inure to the benefit of and be binding upon the Offerors and the
Underwriters 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
Offerors and their respective successors and the controlling persons and
officers and directors referred to in Sections 6 and 7 and their heirs and
legal representatives, any legal or equitable right,





                                      -51-

Securities from any Underwriter shall be deemed to be a successor by reason
merely of such purchase.

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