Company files a registration statement with the Commission pursuant to Section
462(b) of the 1933 Act Regulations (the "RULE 462(b) REGISTRATION STATEMENT"),
then after such filing, all references to "Registration Statement" shall be
deemed to include the Rule 462(b) Registration Statement; and provided, further,

that the Prospectus or any such amendment or supplement was issued and at the
Closing Date, included or will include an untrue statement of a material fact or
omitted or will 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 Company elects to rely upon Rule 434 of the 1933

information furnished to the Company in writing by any Underwriter through

Regulation S-T.

                 (iii) The documents incorporated or deemed to be incorporated

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 quarterly

with past practice or the applicable charter document or supplement thereto,

Michigan, with corporate power and authority to own, lease and operate its
properties and to conduct its business as presently conducted and as described
in the Prospectus and to enter into and perform its obligations under, or as
contemplated under, this Agreement. The Company is duly qualified as a foreign
corporation to transact business and is in good standing in each jurisdiction in
which such qualification is required, whether by reason of the ownership or
leasing of property or the conduct of business, except where the failure to so
qualify or be in good standing would not, singly or in the aggregate, have a
Material Adverse Effect.

                  (viii) Each subsidiary of the Company has been duly
incorporated and is validly existing as a corporation in good standing under the
laws of the jurisdiction of its incorporation, has the corporate power and

jurisdiction in which such qualification is required, whether by reason of the
ownership or leasing of property or the conduct of business, except where the

aggregate, have a Material Adverse Effect. Except as otherwise stated in the
Registration Statement and the Prospectus, all of the issued and outstanding
shares of capital stock of each subsidiary of the Company have been duly
authorized and validly issued, are fully paid and non-assessable and all such
shares are owned by the Company, directly or through its subsidiaries, free and
clear of any security interest, mortgage, pledge, lien, encumbrance, claim or
equity. None of the outstanding shares of capital stock of the subsidiaries was
issued in violation of preemptive or other similar rights arising by operation
of law, under the charter or by-laws of any subsidiary or under any agreement to
which the Company or any subsidiary is a party, or otherwise.

                    (ix) The shares of issued and outstanding capital stock of
the Company have been duly authorized and validly issued and are fully paid and
non-assessable; none of the outstanding shares of capital stock of the Company

agreement to which the Company or any of its subsidiaries is a party or
otherwise.

                     (x) This Agreement has been duly authorized, executed and
delivered by the Company.

                    (xi) The Securities have been duly authorized for issuance
and sale pursuant to this Agreement and at the Closing Date, will have been duly
executed by the Company and, when authenticated in the manner provided for in
the Indenture and delivered by the Company against payment of the purchase price
therefor, will constitute legal, valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms


                                       -5-




<PAGE>   6



except to the extent that enforcement thereof may be limited by bankruptcy,
insolvency, reorganization, moratorium or other similar laws relating to or
affecting creditors' rights generally or by general principles of equity
(regardless of whether enforcement is considered in a proceeding at law or in
equity) (the "BANKRUPTCY EXCEPTIONS"). The Securities will be in the form
contemplated by, and entitled to the benefits of, the Indenture and conform in
all material respects to the description thereof contained in the Prospectus and
will be in substantially the form filed or incorporated by reference, as the
case may be, as an exhibit to the Registration Statement.

                  (xii)  The Collateral Bonds have been duly authorized for
issuance and delivery to the Trustee, and at the Closing Date will have been
duly executed by the Company and, when authenticated in the manner provided for
in the Secured Indenture and delivered by the Company as security for the
Securities, will constitute legal, valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms except to the
extent that enforcement thereof may be limited by the Bankruptcy Exceptions. The
Collateral Bonds will be in the form contemplated by, and entitled to the
benefits of, the Secured Indenture and conform in all material respects to the
description thereof contained in the Prospectus and will be substantially in the
form filed or incorporated by reference, as the case may be, as an exhibit to
the Registration Statement.

                  (xiii) The Indenture has been duly and validly authorized,
executed and delivered by the Company and qualified under the 1939 Act and
constitutes a valid and legally binding instrument, enforceable against the
Company in accordance with its terms except to the extent that the enforcement
thereof may be limited by the Bankruptcy Exceptions; the Indenture conforms in
all material respects to the description thereof contained in the Prospectus and
will be in substantially the form filed or incorporated by reference, as the
case may be, as an exhibit to the Registration Statement.

                  (xiv)  The issuance and delivery by the Company of the
Collateral Bonds to the Trustee constitute a sale by the Company of the
Collateral Bonds to the Trustee as of the Closing Date or, if not a sale, the
grant by the Company to the Trustee of a perfected security interest in the
Collateral Bonds for the benefit of the holders of the Senior Notes.

                  (xv)   The Secured Indenture constitutes a legally valid and
direct enforceable first mortgage lien, except as the same may be limited by the
laws of the State of Michigan (where all of the property covered thereby is
located) affecting the remedies for the enforcement of the security provided for
therein, which laws do not make inadequate the remedies necessary for the
realization of the benefits of such security, or as the same may be limited by
the Bankruptcy Exceptions, upon substantially all of the Company's properties
and franchises, now owned or hereafter acquired, free from all prior liens,
charges or encumbrances, except as set forth in subparagraph xxiii below, and in
the case of property hereafter acquired, any thereof existing at the time of
acquisition.

                  (xvi) None of the Company or any of its subsidiaries is in
violation of its charter or by-laws or in default in the performance or
observance of any material obligation, agreement, covenant or condition
contained in any contract, indenture, mortgage, deed of trust, note, lease, loan
or credit agreement or any other agreement or instrument to which the Company or
any of its subsidiaries is a party or by which any of them may be bound, or to
which any of the property or assets of the Company or any of its subsidiaries is
subject, or in violation of any applicable law, rule or regulation or any
judgment, order, writ or decree of any government, governmental instrumentality
or court, domestic or foreign, having jurisdiction over the Company or any of
its subsidiaries or any of their respective properties or assets, which
violation or default would, singly or in the aggregate, have a Material Adverse
Effect.

Securities, the Thirty-fifth Supplemental Indenture to the Original Secured
Indenture, the Collateral Bonds and any other agreement or instrument entered
into or issued or to be entered into or issued by the Company in connection with
the transactions contemplated hereby or thereby; and the consummation of the
transactions contemplated herein and therein and in the Registration Statement
and the Prospectus (including the issuance and sale of the Securities and the
issuance and pledge of the Collateral Bonds, and the use of the proceeds from
the sale of the Securities as described in the Prospectus under the caption "Use
of Proceeds"); and compliance by the Company with its obligations hereunder and
thereunder have been duly authorized by all necessary corporate action and do
not and will not, whether with or without the giving of notice or passage of
time or both, conflict with or constitute a breach of, or default under, or
result in the creation or imposition of any lien, charge or encumbrance upon any
property or assets of the Company or any of its subsidiaries pursuant to any
contract, indenture, mortgage, deed of trust, loan or credit agreement, note,
lease or other agreement or instrument to which the Company or any of its
subsidiaries is a party or by which any of them may be bound (other than the
lien of the Indenture), or to which any property or assets of the Company or any
subsidiary thereof is subject (except for such conflicts, breaches or defaults
or liens, charges or encumbrances that would not, singly or in the aggregate,
result in a Material Adverse Effect), nor will such action result in any
violation of the provisions of the charter of by-laws of the Company or any of
its subsidiaries or any applicable law, statute, rule or regulation, judgment,
order, writ or decree of any government, governmental instrumentality or court,
domestic or foreign, having jurisdiction over the Company or any of its
subsidiaries or any of their respective property, assets or operations.

                  (xviii) On the Closing Date, the Remarketing Agreements will
have been validly authorized, executed and delivered by the Company and will
constitute a valid and legally


                                       -7-

binding instrument, enforceable against the Company in accordance with its terms
except to the extent that the enforcement thereof may be limited by the
Bankruptcy Exceptions.

                  (xix)   No labor dispute with the employees of the Company or
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 disturbance by
the employees of any of its or any of its subsidiary's principal suppliers,
manufacturers, customers or contractors which, in either case, may reasonably be
expected to result in a Material Adverse Effect.

                  (xx)    There is no action, suit, proceeding, inquiry or

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

the Registration Statement or the filing of any supplement or amendment to the
Prospectus, (ii) of the receipt of any comments from the Commission, (iii) of
any request by the Commission for any amendment to the Registration Statement or
any amendment or supplement to the Prospectus or for additional information and

effectiveness of the Registration Statement or of any order preventing or
suspending the use of any preliminary prospectus or Prospectus, or of the
suspension of the qualification of the Securities for offering or sale in any
jurisdiction, or of the initiation or threatening of any proceedings for any of
such purposes. The Company will make every reasonable effort to prevent the
issuance of any stop order and, if any stop order is issued, to obtain the
lifting thereof at the earliest possible moment.

         (c) The Company will give the Representatives notice of their 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

or otherwise; will furnish the Representatives with copies of any such Rule
462(b) Registration Statement, Term Sheet, amendment, supplement or revision a
reasonable amount of time prior to such proposed filing or use, as the case may
be; and will not file any such Rule 462(b) Registration Statement, Term Sheet,
amendment, supplement or revision to which the Representatives or counsel for
the Underwriters shall object.

         (d) The Company has furnished or will deliver to the Representatives
and counsel for the Underwriters, without charge, signed copies of the

signed copies of all consents and certificates of experts, and will also deliver
to the Representatives, without charge, a conformed copy of the Registration
Statement as originally filed and of each amendment thereto (without exhibits)
for each of the Underwriters. The copies of the Registration Statement and each
amendment thereto furnished to the Underwriters will be identical to the

completion of the distribution of the Securities as contemplated in this
Agreement and in the Prospectus. If at any time when a prospectus is required by
the 1933 Act or the 1934 Act to be delivered in connection with sales of the
Securities, any event shall occur or condition shall exist as a result of which
it is necessary, in the opinion of counsel for the Underwriters or for the
Company, to amend the Registration Statement or amend or supplement any
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 time to amend the Registration Statement or
amend or supplement any Prospectus in order to comply with the requirements of
the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and
file with the Commission, subject to Section 3(c), such amendment or supplement
as may be necessary to correct such statement or omission or to make the
Registration Statement or the Prospectus comply with such requirements, and the
Company will furnish to the Underwriters, without charge, such number of copies
of such amendment or supplement as the Underwriters may reasonably request.

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

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

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

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 this Agreement, the
Company will prepare, and file or transmit for filing with the Commission in
accordance with such Rule 430A or Rule 434 and Rule 424(b) of the 1933 Act
Regulations, copies of an amended Prospectus, or Term Sheet, or, if required by
such Rule 430A, a post-effective amendment to the Registration Statement
(including an amended Prospectus), containing all information so omitted.

         (l) If the Company elects to rely upon Rule 462(b), the Company shall
file a Rule 462(b) Registration Statement with the Commission in compliance with
Rule 462(b) and pay the applicable fees in accordance with Rule 111 of the 1933
Act Regulations by the earlier of (i) 10:00 p.m. Eastern time on the date of

         (o) During a period of fifteen days from the date of the Prospectus,
the Company will not, without the prior written consent of Salomon Brothers Inc,
directly or indirectly, issue, pledge, sell, offer to sell, grant any option for
the sale of or otherwise transfer or dispose of, any debt securities of the
Company which mature more than one year after the Closing Date and which are
substantially similar to the Securities, without the prior written consent of
Salomon Brothers Inc, except for the offer by the Company of $75,000,000
aggregate principal amount of its Extendable MandatOry Par Put Remarketed
Securities(sm) ("MOPPRS(sm)") due June 30, 2038.

         (p) 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.

Ronald E. Christian, Esq., Vice President, General Counsel and Secretary of the
Company, in form and substance satisfactory to counsel for the Underwriters,
together with signed or reproduced copies of such letter for each of the other
Underwriters, to the effect that:

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

                                 (ii) The Company has corporate power and
         authority to own, lease and operate its properties and to conduct its

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

                                 (iv) The shares of issued and outstanding
         capital stock of the Company have been duly authorized and validly
         issued and are fully paid and non-assessable; and none of the
         outstanding shares of capital stock were issued in violation of
         preemptive or other similar rights arising by operation of law, under
         the charter or by-laws of the Company; under any agreement to which the
         Company, or any of its subsidiaries is a party, or otherwise.

                                 (v) The Securities are in the form contemplated
         by the Indenture, have been duly and validly authorized by the Company
         and, when executed by the Company and authenticated by the Trustee in
         the manner provided for in the Indenture and delivered by the Company
         against payment of the purchase price therefor, will constitute legal,
         valid and binding obligations of the Company, enforceable against the
         Company in accordance with their terms, except to the extent that
         enforcement thereof may be limited by the Bankruptcy Exceptions. Each
         holder of the Securities will be entitled to the benefits provided by

                                      -16-

         enforcement thereof may be limited by the Bankruptcy Exceptions. The
         form of certificate used to evidence the Collateral Bonds is in due and
         proper form and complies with the requirements of the Secured
         Indenture; and the Collateral Bonds and the Secured Indenture conform
         in all material respects to the descriptions thereof contained in the
         Prospectus.

                                 (vii) The issuance and delivery by the Company
         of the Collateral Bonds to the Trustee constitute a sale by the Company
         of the Collateral Bonds to the Trustee as of the Closing Date or, if
         not a sale, the grant by the Company to the Trustee of a perfected
         security interest in the Collateral Bonds for the benefit of the
         holders of the Senior Notes.

                                 (viii) Except as to property acquired
         subsequent to the date of execution of the Thirty-fourth Supplemental
         Indenture, the Company has good and marketable title to the property
         specifically or generally described in the Secured Indenture (except
         such property as may have been disposed of or released from the lien
         thereof in accordance with the terms thereof) subject only to the lien
         of the Secured Indenture, to permitted liens, as defined in the Secured
         Indenture, as to property acquired by the Company subsequent to the
         execution of the Original Secured Indenture, to any liens existing
         thereon or purchase money liens placed thereon at the time of such
         acquisition as permitted by the Secured Indenture, and to certain other
         reservations, rights of grantors under revocable permits, easements,
         licenses, zoning laws and ordinances and restrictions and minor defects
         or irregularities of title which do not, in the opinion of such
         counsel, materially impair the use of the property affected thereby in
         the operation of the business of the Company; the pipeline,
         distribution main and underground gas storage easements enjoyed by the
         Company and its subsidiaries are valid, subsisting and enforceable
         easements with such exceptions as are not material and do not interfere
         with the conduct of the business of the Company and its subsidiaries.

                                 (ix) The Secured Indenture constitutes a
         legally valid and enforceable first mortgage lien, except as the same
         may be limited by the laws of the State of Michigan (where the property
         covered thereby is located) affecting the remedies for the enforcement
         of the security provided for therein, which laws do not, in the opinion
         of such counsel, make inadequate the remedies necessary for the
         realization of the benefits of such security, or as the same may be
         limited by the Bankruptcy Exceptions, upon substantially all of the
         Company's properties and franchises, now owned or hereafter acquired,
         free from all prior liens, charges or encumbrances other than the lien
         of the Secured Indenture, permitted liens, as defined in the Secured
         Indenture, as to property acquired by the Company subsequent to the
         execution of the Original Secured Indenture, any liens existing thereof
         or purchase money liens placed thereon at the time of such acquisition
         as permitted by the grantors under revocable permits, easements,
         licenses, zoning laws and ordinances and restrictions and minor defects
         or irregularities of title

         which do not, in the opinion of such counsel, materially impair the use
         of the property affected thereby in the operation of the business of
         the Company.

                                 (x) All taxes and fees required to be paid by
         the laws of the State of Michigan and jurisdictional subdivisions
         thereof with respect to the execution of the Thirty-Fifth Supplemental
         Indenture and the issuance and delivery of the Collateral Bonds have
         been paid.

                                 (xi) Each subsidiary of the Company has been
         duly incorporated and is validly existing as a corporation in good
         standing under the laws of the jurisdiction of its incorporation, has
         the corporate power and authority to own, lease and operate its
         properties and to conduct its business as presently conducted and as
         described in the Prospectus, and is duly qualified as a foreign
         corporation to transact business and is in good standing in each
         jurisdiction in which such qualification is required, whether by reason
         of the ownership or leasing of property or the conduct of business,
         except where the failure to so qualify or be in good standing would
         not, individually or in the aggregate, have a Material Adverse Effect.
         Except as otherwise disclosed in the Registration Statement and the
         Prospectus, all of the issued and outstanding capital stock of each
         such subsidiary of the Company has been duly authorized and validly
         issued, is fully paid and non-assessable and all such shares are owned

         of such counsel's knowledge, free and clear of any security interest,

         outstanding shares of capital stock of any subsidiary of the Company
         was issued in violation of preemptive or other similar rights of any
         securityholder of such subsidiary.

                                 (xii) This Agreement has been duly authorized,

         any Rule 462(b) Registration Statement, has been declared effective

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

                                 (xiv) The Registration Statement, including any
         Rule 462(b) Registration Statement, the Rule 430A Information and the

         documents incorporated by reference therein, as of their respective
         effective or issue dates (other than the financial statements and

                                 (xv) The documents incorporated by reference in
         the Prospectus (other than the financial statements and supporting
         schedules therein, as to which such counsel need express no opinion),
         when they were filed with the Commission complied as to form in all
         material respects with the requirements of the 1934 Act and the 1934
         Act Regulations.

         requirements for use of Form S-3 under the 1933 Act Regulations.

                                 (xvii) The Indenture has been duly and validly
         authorized, executed and delivered by the Company and qualified under
         the 1939 Act and, assuming due authorization, execution and delivery
         thereof by the Trustee, constitutes a valid and legally binding

         to the Original Secured Indenture has been duly and validly authorized,

                                 (xx) Each of the Remarketing Agreements has
         been validly authorized, executed and delivered by the Company and will
         constitute a valid and legally binding instrument, enforceable against

         issued or to be entered into or issued by the Company in connection
         with the transactions contemplated hereby or thereby; the consummation
         of the transactions contemplated herein and therein and in the

         of the provisions of the charter or by-laws of the Company or any if
         its subsidiaries, or any applicable law, statute, rule, regulation,
         judgment, order, writ or decree, known to such counsel, of any

         Agreement, the Indenture, the Thirty-Fifth Supplemental Indenture to
         the Original Secured Indenture or the Remarketing Agreements, or the

         ordinary routine litigation incidental to the business of the Company
         or its subsidiaries, could not reasonably be expected to, singly or in

         and information, neither the Company nor any of its subsidiaries is in
         violation of its charter or by-laws and no default by the Company or
         any subsidiary exists in the due performance or observance of any
         material obligation, agreement, covenant or condition contained in any
         contract, indenture, mortgage, loan or credit agreement, note, lease,
         or other agreement or instrument to which the Company or any of its
         subsidiaries is a party or by which it or any of them or any of their
         respective properties or assets are bound, except for violations and
         defaults that would not, singly or in the aggregate, result in a

         contracts and other documents to which the Company or any of its

         connection with the authorization, issuance and validity of the
         Securities and the sale of the Securities in accordance with this
         Agreement (other than the filing of post-issuance reports, the
         non-filing of which would not render the Securities invalid), and in

         Company of its obligations in this Agreement, the Thirty-Fifth
         Supplemental Indenture, the Indenture, the Remarketing Agreements and
         the Securities.

                                 (xxix) The Company and its subsidiaries possess
         all licenses, franchises, permits, certificates, authorizations,
         approvals, consents, orders and other operating rights (collectively,
         the "Governmental Licenses") issued by the Federal Energy Regulatory
         Commission; the State of Michigan, and all other federal, state, local
         or foreign regulatory agencies or bodies, governmental authorities or
         agencies necessary for the ownership or lease of the material
         properties owned or leased by each of them and for the operation of the
         business carried on by each of them as described in the Registration
         Statement and the Prospectus except where the failure to so comply
         would not, singly or in the aggregate, have a Material Adverse Effect;
         all such licenses, franchises, permits, certificates, authorizations,
         approvals, consents and orders are in full force and effect, except
         when the failure of such Governmental Licenses to be in full force
         would not, singly or in the aggregate, have a Material Adverse Effect,
         and contain no unduly burdensome provisions that would interfere with
         the conduct of the business of the Company or its subsidiaries,
         considered as one enterprise and, except as otherwise set forth in the
         Registration Statement or the Prospectus, there are no legal or
         governmental proceedings pending or threatened that would result in a
         material modification, suspension or revocation thereof.

                                 (xxx) Each of the Company and its subsidiaries
         has good and marketable title to all material real and personal
         property owned by each of them, in each case, free and clear of all
         mortgages, pledges, liens, security interests, claims, restrictions or
         encumbrances of any kind except such as (a) are described in the
         Registration Statement and the Prospectus or (b) do not, singly or in
         the aggregate, materially affect the value of such property and do not
         materially interfere with the use made and proposed to be made of such
         property by the Company or any of its subsidiaries; and any real
         property and buildings held under lease by the Company, or its
         subsidiaries are held by them under valid, subsisting and enforceable
         leases with such exceptions as are not material and do not interfere
         with the conduct of the business of the Company or such subsidiaries.

                                 (xxxi) The Company is not an "investment
         company" or an entity under the "control" of an "investment company" as
         such terms are defined in the 1940 Act.

                                 (xxxii) MCN and the Company are presently
         exempt from the provisions of the Public Utility Holding Company Act of
         1935 (except Section 9 thereof) which would otherwise require either of
         them to register 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 Rule
         430A Information and Rule 434 Information (if


                                      -22-

         applicable)(except for financial statements and the notes thereto, the
         financial schedules and any other financial data included or
         incorporated by reference therein, as to which such counsel need
         express no opinion), at the time such Registration Statement became
         effective or at the date of this Agreement, contained an untrue
         statement of a material fact or omitted to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading or that the Prospectus or any amendment or
         supplement thereto (except for financial statements and the notes
         thereto, the financial schedules, and any other financial data included
         or incorporated by reference therein, as to which such counsel need
         express no opinion), at the time the Prospectus were issued, at the
         time of any such amended or supplemented Prospectus were issued or at
         the Closing Date, included or includes an untrue statement of a
         material fact or omitted or omits to state a material fact necessary in
         order to make the statements therein, in the light of the circumstances
         under which they were made, not misleading.

                  (2) The favorable opinion, dated as of the Closing Date, of
Skadden, Arps, Slate, Meagher & Flom LLP, special counsel to the Company, in
form and substance satisfactory to counsel for the Underwriters, together with
signed or reproduced copies of such letter for each of the other Underwriters,
to the effect that:

                                 (i) The Registration Statement, including any
         Rule 462(b) Registration Statement, is effective under the 1933 Act;
         any required filing of the Prospectus pursuant to Rule 424(b) has been

                                 (ii) The Registration Statement, including any
         Rule 462(b) Registration Statement, the Rule 430A Information and the
         Rule 434 Information, as applicable, the Prospectus, excluding the
         documents incorporated by reference therein, and each amendment or
         supplement to the Registration Statement and Prospectus, excluding the
         documents incorporated by reference therein, as of their respective
         effective or issue dates (other than the financial statements and
         supporting schedules included therein, as to which such counsel need
         express no opinion), complied as to form in all material respects with
         the requirements of the 1933 Act and the 1933 Act Regulations.

                                 (iii) The statements in the Prospectus under

         under Michigan law, each of them is a valid and legally binding
         agreement of the Company, enforceable against the Company in accordance
         with its terms except to the extent that the enforcement thereof may be
         limited by the Bankruptcy Exceptions.

                                 (v) The Securities, the Indenture and the
         Remarketing Agreements conform in all material respects to the
         descriptions thereof contained in the Prospectus.

                                 (vi) No authorization, approval, consent,
         order, registration, qualification of or with any court or federal or

         issuance and sale of the Securities by the Company to the Underwriters,
         or the issuance and delivery to the Trustee by the Company of the

         which such counsel need express no opinion.

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

                  (3) The favorable opinion, dated as of the Closing Date, of
LeBoeuf, Lamb, Greene & MacRae, L.L.P., counsel for the Underwriters, together
with signed or reproduced copies of such letter for each of the other
Underwriters, in form and substance satisfactory to the Representatives, with
respect to such 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 such
opinion, LeBoeuf, Lamb, Greene & MacRae, L.L.P. may rely as to certain matters
of Michigan law upon the opinion of Ronald E. Christian, Esq., counsel for the
Company, which shall be delivered in accordance with Section 5(b)(1) hereof.

                  (4) The opinion, dated as of the Closing Date, of Skadden,

the effect that, subject to the qualifications and limitations stated therein
and in the Prospectus, the statements set forth in the Prospectus under the

certificate of the President or a Vice President of the Company and of the Chief
Financial Officer or Chief Accounting Officer of the Company, dated as of the

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

                           (A) the unaudited condensed consolidated financial
                  statements set forth in the Company's Quarterly Reports on

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

                  balance sheet items included in the Prospectus, as amended or
                  supplemented, do not agree with the corresponding items in the
                  unaudited consolidated financial statements from which such
                  data and items were derived;

                           (C) any unaudited pro forma consolidated condensed
                  financial statements or any unaudited pro forma consolidating
                  financial statements included or incorporated by reference in
                  the 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 and the 1934 Act and the 1934 Act Regulations or
                  the pro forma adjustments have not been properly applied to
                  the historical amounts in the compilation of those statements;

                           (D) as of a specified date not more than five days
                  prior to the date of this Agreement, there has been any
                  decrease or increase in the capital stock or any increase or

                  statement of financial position of the Company and its
                  subsidiaries incorporated by reference in the Registration
                  Statement and the Prospectus as amended or supplemented,

                  discloses have occurred or may occur or which are described in
                  such letter; and

                           (E) for the period from the date of the latest
                  consolidated financial statements included or incorporated by
                  reference in the Prospectus, as amended or supplemented, to

                  for Common Stock of the Company and its consolidated
                  subsidiaries, or any increases in any items specified by the
                  Representatives, in each case as compared with the
                  corresponding period in the preceding year and with any other
                  period of corresponding length specified by the
                  Representatives, except in each case for increases or
                  decreases which the Prospectus, as amended or supplemented,
                  including financial information incorporated by reference,
                  discloses have occurred or may occur or which are described in
                  such letter; and

                           (F) the unaudited condensed 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.

                  (iv) 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, as amended or supplemented, 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;

                  (v) In addition to the limited procedures, reading of minutes,
         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 and financial
         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

         Representatives, and have compared certain of such amounts, percentages

                  (vi) If applicable and agreed to by the parties to this
         Agreement, they have made a review in accordance with standards
         established by the American Institute of Certified Public Accountants
         of the selected financial data, pro forma financial information,
         prospective financial statements, consolidating financial statements
         and/or condensed financial statements derived from audited financial
         statements of the Company for the periods specified in such letter, as
         indicated in their reports thereon, copies of which have been furnished
         to the Representatives.

         (e) On the Closing Date, the Representatives shall have received from
Deloitte & Touche LLP a letter, dated as of the Closing Date, to the effect that
they reaffirm the statements made in the letter furnished pursuant to subsection

         (f) On the Closing Date, the Securities shall be rated at least "A2" by

of the Company or of the Securities.

         (g) On the Closing Date, counsel for the Underwriters shall have been

or warranties, or the fulfillment of any of the conditions herein contained; and
all proceedings taken by the Company in connection with the issuance and sale of
the Securities as herein contemplated shall be satisfactory in form and

any party to any other party except as provided in Section 4 and except that
Sections 1, 6 and 7 shall survive any such termination and remain in full force

         SECTION 6.  Indemnification and Contribution.

         (a) The Company agrees to indemnify and hold harmless each Underwriter,
the directors, officers, employees and agents of each Underwriter and each
person who controls any Underwriter within the meaning of either the 1933 Act or
the 1934 Act against any and all losses, claims, damages or liabilities, joint
or several, to which they or any of them may become subject


                                      -28-




<PAGE>   29



under the 1933 Act, the 1934 Act or other Federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of a material fact contained in
the registration statement for the registration of the Securities as originally
filed or in any amendment thereof, or in any Preliminary Prospectus or the
Prospectus, or in any amendment thereof or supplement thereto, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, and agrees to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
any Underwriter through the Representatives specifically for inclusion therein;
provided, however, that the indemnification contained in this paragraph (a) with
respect to any Preliminary Prospectus shall not inure to the benefit of any
Underwriter (or to the benefit of any person controlling such Underwriter) on
account of any such loss, claim, damage, liability or expense arising from the
sale of the Securities by such Underwriter to any person if a copy of the
Prospectus shall not have been delivered or sent to such person within the time
required by the Act and the regulations thereunder, and the untrue statement or
alleged untrue statement or omission or alleged omission of a material fact
contained in such Preliminary Prospectus was corrected in the Prospectus,
provided that the Offerors have delivered the Prospectus to the several
Underwriters in requisite quantity on a timely basis to permit such delivery or
sending. This indemnity agreement will be in addition to any liability which the
Company may otherwise have.

         (b) Each Underwriter severally and not jointly agrees to indemnify and
hold harmless the Company, each of its directors, each of its officers who signs
the Registration Statement, and each person who controls the Company within the
meaning of either the 1933 Act or the 1934 Act, to the same extent as the
foregoing indemnity from the Company to each Underwriter, but only with
reference to written information relating to such Underwriter furnished to the
Company by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity. This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have. The Company acknowledges that the statements
set forth in the last paragraph of the cover page regarding delivery of the
Securities, the legend in block capital letters on page 3 related to
stabilization, syndicate covering transactions and penalty bids and, under the
heading "Underwriting" or "Plan of Distribution", (i) the sentences related to
concessions and reallowances and (ii) the paragraph related to stabilization,
syndicate covering transactions and penalty bids in any Preliminary Prospectus
and the Prospectus constitute the only information furnished in writing by or on
behalf of the several Underwriters for inclusion in any Preliminary Prospectus
or the Prospectus.

         (c) Promptly after receipt by an indemnified party under this Section 6
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 6, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
satisfactory to the indemnified party. Notwithstanding the indemnifying party's
election to appoint counsel to represent the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel (including
local counsel), and the indemnifying party shall bear the reasonable fees, costs
and expenses of such separate counsel if (i) the use of counsel chosen by the
indemnifying party to represent the indemnified party would present such counsel
with a conflict of interest, (ii) the actual or potential defendants in, or
targets of, any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, (iii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. An indemnifying party will
not, without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding.

         (d) In the event that the indemnity provided in paragraph (a) or (b) of
this Section 6 is unavailable to or insufficient to hold harmless an indemnified
party for any reason, the Company and the Underwriters severally agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Underwriters may be subject in such proportion as is appropriate to reflect
the relative benefits received by the Company on the one hand and by the
Underwriters on the other from the offering of the Securities; provided,
however, that in no case shall any Underwriter (except as may be provided in any
agreement among underwriters relating to the offering of the Securities) be
responsible for any amount in excess of the underwriting discount or commission
applicable to the Securities purchased by such Underwriter hereunder. If the
allocation provided by the


                                      -30-




<PAGE>   31

immediately preceding sentence is unavailable for any reason, the Company and
the Underwriters severally shall contribute in such proportion as is appropriate
to reflect not only such relative benefits but also the relative fault of the
Company on the one hand and of the Underwriters on the other in connection with
the statements or omissions which resulted in such Losses as well as any other
relevant equitable considerations. Benefits received by the Company shall be
deemed to be equal to the total net proceeds from the offering (before deducting
expenses) received by it, and benefits received by the Underwriters shall be
deemed to be equal to the total underwriting discounts and commissions, in each
case as set forth on the cover page of the Prospectus. Relative fault shall be
determined by reference to, among other things, whether any untrue or any
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information provided by the Company on the
one hand or the Underwriters on the other, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such untrue statement or omission. The Company and the Underwriters agree that
it would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 6, each person who controls an Underwriter within the meaning of
either the Act or the Exchange Act and each director, officer, employee and
agent of an Underwriter shall have the same rights to contribution as such
Underwriter, and each person who controls the Company within the meaning of
either the Act or the Exchange Act, each officer of the Company who shall have
signed the Registration Statement and each director of the Company shall have
the same rights to contribution as the Company, subject in each case to the
applicable terms and conditions of this paragraph (d).

         SECTION 7. Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement, or contained in certificates of officers of the Company or any of its
subsidiaries submitted pursuant hereto, shall remain operative and in full force
and effect, regardless of any termination or cancellation of this Agreement or
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 and payment for
the Securities to the Underwriters.

         SECTION 8.  Termination of Agreement.

         (a) The Representatives may terminate this Agreement, by notice to the
Company at any time on or prior to the Closing Date, if (i) there has been,
since the date of this Agreement or since the respective dates as of which
information is given in the Prospectus, any material adverse change or any
development which could reasonably be expected to result in a 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, or (ii) there has occurred any material adverse
change in the financial markets in the United States or any outbreak of

                                      -31-




<PAGE>   32




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 Representatives, impracticable to
market the Securities or to enforce contracts for the sale of the Securities, or
(iii) if trading in any securities of the Company or any of its affiliates has
been suspended or limited by the Commission, the National Association of
Securities Dealers, Inc. ("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 is terminated pursuant to this Section 8, 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 9. Default by One or More of the Underwriters. If one or more
of the Underwriters shall fail at the Closing Date to purchase the Securities
which it or they are obligated to purchase under this 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 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, 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
number of Securities to be purchased on such date, each of 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 of Defaulted Securities exceeds 10% of the number of
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 9 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 Date 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. As used herein, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 9.

"Trustee"), which will be secured by the concurrent issuance and delivery to the

<PAGE>   2

INDENTURE"), as supplemented and amended by thirty-five indentures supplemental

Secured Indenture and all supplemental indentures thereto being referred to
collectively herein as the "Secured Indenture"), in a principal amount equal to
that of and having other terms that mirror those of the Securities. The Company

"COMMISSION") a registration statement on Form S-3 (No. 333-56333) covering the
registration of debt securities of the Company, including 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
this 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, are collectively referred to herein
as the "Prospectus"; provided, however, that all references to the "Registration
Statement" 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 this Agreement; provided, further, that if the
Company files a registration statement with the Commission pursuant to Section
462(b) of the 1933 Act Regulations (the "RULE 462(b) REGISTRATION STATEMENT"),
then after such filing, all references to "Registration Statement" shall be
deemed to include the Rule 462(b) Registration statement; and provided, further,
that if the Company elects to rely upon Rule 434 of the 1933 Act Regulations,
the term "PROSPECTUS" shall refer to the final or preliminary prospectus and the
applicable term sheet (a "TERM SHEET") and all references in this Agreement to
the date of such Prospectus shall mean the date of the applicable 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 this
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
electronically transmitted copy thereof filed with the Commission pursuant to

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 Trust Indenture Act of 1939, as amended (the

<PAGE>   4




                  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 when so
filed in all material respects with the 1933 Act Regulations and each

Regulation S-T.

                  (iii) The documents incorporated or deemed to be incorporated
by reference in the Registration Statement and the Prospectus, at the time they

and the statements of operations, stockholders' equity and cash flows of the
Company and its consolidated subsidiaries for the periods specified. Such

accordance with GAAP the information required to be stated therein. The ratio of

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.

                  (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

<PAGE>   12




         (b) The Company, subject to Section 3(c), will comply with the
requirements of Rule 430A or Rule 434 of the 1933 Act Regulations, as
applicable, and will notify the Representatives immediately, and confirm the
notice in writing, (i) of the effectiveness of any post-effective amendment to
the Registration Statement or the filing of any supplement or amendment to the
Prospectus, (ii) of 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 and
(iv) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or of any order preventing or
suspending the use of any preliminary prospectus or Prospectus, or of the
suspension of the qualification of the Securities for offering or sale in any
jurisdiction, or of the initiation or threatening of any proceedings for any of
such purposes. The Company will make every reasonable effort to prevent the
issuance of any stop order and, if any stop order is issued, to obtain the
lifting thereof at the earliest possible moment.

         (c) The Company will give the Representatives notice of their 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 Representatives with copies of any such Rule
462(b) Registration Statement, Term Sheet, amendment, supplement or revision a
reasonable amount of time prior to such proposed filing or use, as the case may
be; and will not file any such Rule 462(b) Registration Statement, Term Sheet,
amendment, supplement or revision to which the Representatives or counsel for
the Underwriters shall object.

         (d) The Company has furnished or will deliver to the Representatives
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 the Representatives, without charge, a conformed copy of the Registration
Statement as originally filed and of each amendment thereto (without exhibits)
for each of the Underwriters. 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

Prospectus and any amendments or supplements thereto furnished to the
Underwriters will be


                                      -12-

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 Prospectus. If at any time when a prospectus is required by
the 1933 Act or the 1934 Act to be delivered in connection with sales of the
Securities, any event shall occur or condition shall exist as a result of which
it is necessary, in the opinion of counsel for the Underwriters or for the
Company, to amend the Registration Statement or amend or supplement any
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 time to amend the Registration Statement or
amend or supplement any Prospectus in order to comply with the requirements of
the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and
file with the Commission, subject to Section 3(c), such amendment or supplement
as may be necessary to correct such statement or omission or to make the
Registration Statement or the Prospectus comply with such requirements, and the
Company will furnish to the Underwriters, without charge, such number of copies
of such amendment or supplement as the Underwriters may reasonably request.

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

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

         (i) The Company will use the net proceeds received by it from the sale
of the Securities in the manner specified in the Prospectus under the caption
"USE OF PROCEEDS."

the Prospectus under the caption "DESCRIPTION OF THE NOTES--Security; Release
Date."

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 this Agreement, the

                  (1) The favorable opinion, dated as of the Closing Date, of
Ronald E. Christian, Esq., Vice President, General Counsel and Secretary of the
Company, in form and substance satisfactory to counsel for the Underwriters,
together with signed or reproduced copies of such letter for each of the other
Underwriters, to the effect that:

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

                                 (ii)  The Company has corporate power and
         authority to own, lease and operate its properties and to conduct its
         business as presently conducted and as described in the Prospectus and
         to enter into and perform its obligations under this Agreement.

                                 (iii) The Company is duly qualified as a
         foreign corporation to transact business and is in good standing in
         each jurisdiction in which such qualification is required, whether by
         reason of the ownership or leasing of property or the conduct

         of business, except where the failure so to qualify or to be in good
         standing would not, individually or in the aggregate, result in a
         Material Adverse Effect.

                                 (iv)  The shares of issued and outstanding
         capital stock of the Company have been duly authorized and validly
         issued and are fully paid and non-assessable; and none of the
         outstanding shares of capital stock were issued in violation of
         preemptive or other similar rights arising by operation of law, under
         the charter or by-laws of the Company; under any agreement to which the
         Company, or any of its subsidiaries is a party, or otherwise.

                                 (v)   The Securities are in the form 
         contemplated by the Indenture, have been duly and validly authorized
         by the Company and, when executed by the Company and authenticated by
         the Trustee in the manner provided for in the Indenture and delivered
         by the Company against payment of the purchase price therefor, will
         constitute legal, valid and binding obligations of the Company,
         enforceable against the Company in accordance with their terms, except
         to the extent that enforcement thereof may be limited by the
         Bankruptcy Exceptions. Each holder of the Securities will be entitled
         to the benefits provided by the Indenture; the form of certificate
         used to evidence the Securities is in due and proper form and complies
         with the requirements of the Indenture; and the Securities and the
         Indenture conform in all material respects to the descriptions thereof
         contained in the Prospectus.

                                 (vi)  The Collateral Bonds are in the form
         contemplated by the Secured Indenture, have been duly and validly
         authorized by the Company and, when executed by the Company and
         authenticated by the Trustee in the manner provided for in the
         Indenture, and issued and delivered by the Company to the Trustee as
         security for the Securities, will constitute legal, valid and binding
         obligations of the Company, enforceable against the Company in
         accordance with their terms, except to the extent that 

                                      -16-




<PAGE>   17



         enforcement thereof may be limited by the Bankruptcy Exceptions. The
         form of certificate used to evidence the Collateral Bonds is in due and
         proper form and complies with the requirements of the Secured
         Indenture; and the Collateral Bonds and the Secured Indenture conform
         in all material respects to the descriptions thereof contained in the
         Prospectus.

                                 (vii)  The issuance and delivery by the Company
         of the Collateral Bonds to the Trustee constitute a sale by the Company
         of the Collateral Bonds to the Trustee as of the Closing Date, or, if
         not a sale, the grant by the Company to the Trustee of a perfected
         security interest in the Collateral Bonds for the benefit of the
         holders of the Senior Notes.

                                 (viii) Except as to property acquired
         subsequent to the date of execution of the Thirty-fourth Supplemental
         Indenture, the Company has good and marketable title to the property
         specifically or generally described in the Secured Indenture (except
         such property as may have been disposed of or released from the lien
         thereof in accordance with the terms thereof) subject only to the lien
         of the Secured Indenture, to permitted liens, as defined in the Secured
         Indenture, as to property acquired by the Company subsequent to the
         execution of the Original Secured Indenture, to any liens existing
         thereon or purchase money liens placed thereon at the time of such
         acquisition as permitted by the Secured Indenture, and to certain other
         reservations, rights of grantors under revocable permits, easements,
         licenses, zoning laws and ordinances and restrictions and minor defects
         or irregularities of title which do not, in the opinion of such
         counsel, materially impair the use of the property affected thereby in
         the operation of the business of the Company; the pipeline,
         distribution main and underground gas storage easements enjoyed by the
         Company and its subsidiaries are valid, subsisting and enforceable
         easements with such exceptions as are not material and do not interfere
         with the conduct of the business of the Company and its subsidiaries.

                                 (ix)   The Secured Indenture constitutes a
         legally valid and enforceable first mortgage lien, except as the same
         may be limited by the laws of the State of Michigan (where the property
         covered thereby is located) affecting the remedies for the enforcement
         of the security provided for therein, which laws do not, in the opinion
         of such counsel, make inadequate the remedies necessary for the
         realization of the benefits of such security, or as the same may be
         limited by the Bankruptcy Exceptions, upon substantially all of the
         Company's properties and franchises, now owned or hereafter acquired,
         free from all prior liens, charges or encumbrances other than the lien
         of the Secured Indenture, permitted liens, as defined in the Secured
         Indenture, as to property acquired by the Company subsequent to the
         execution of the Original Secured Indenture, any liens existing thereof
         or purchase money liens placed thereon at the time of such acquisition
         as permitted by the grantors under revocable permits, easements,
         licenses, zoning laws and ordinances and restrictions and minor defects
         or irregularities of title which do not, in the opinion of such
         counsel, materially impair the use of the property affected thereby in
         the operation of the business of the Company.

                                (x)    All taxes and fees required to be paid by
         the laws of the State of Michigan and jurisdictional subdivisions
         thereof with respect to the execution of the Thirty-Fifth Supplemental
         Indenture and the issuance and delivery of the Collateral Bonds have
         been paid.

         duly incorporated and is validly existing as a corporation in good
         standing under the laws of the jurisdiction of its incorporation, has
         the corporate power and authority to own, lease and operate its
         properties and to conduct its business as presently conducted and as
         described in the Prospectus, and is duly qualified as a foreign
         corporation to transact business and is in good standing in each
         jurisdiction in which such qualification is required, whether by reason
         of the ownership or leasing of property or the conduct of business,
         except where the failure to so qualify or be in good standing would
         not, individually or in the aggregate, have a Material Adverse Effect.
         Except as otherwise disclosed in the Registration Statement and the
         Prospectus, all of the issued and outstanding capital stock of each
         such subsidiary of the Company has been duly authorized and validly
         issued, is fully paid and non-assessable and all such shares are owned

         of such counsel's knowledge, free and clear of any security interest,
         mortgage, pledge, lien, encumbrance, claim or equity. None of the
         outstanding shares of capital stock of any subsidiary of the Company
         was issued in violation of preemptive or other similar rights of any
         securityholder of such subsidiary.

         required by Rule 424(b); and, to the best knowledge of such counsel, no
         stop order suspending the effectiveness of the Registration Statement
         or any Rule 462(b) Registration Statement has been issued under the
         1933 Act and no proceedings therefor have been initiated or threatened
         by the Commission.

                                 (xiv) The Registration Statement, including any
         Rule 462(b) Registration Statement, the Rule 430A Information and the
         Rule 434 Information, as applicable, the Prospectus, excluding the
         documents incorporated by reference therein, and each amendment or
         supplement to the Registration Statement and Prospectus, excluding the
         documents incorporated by reference therein, as of their respective
         effective or issue dates (other than the financial statements and
         supporting schedules included therein, as to which such counsel need
         express no opinion), complied as to form in all material respects with
         the requirements of the 1933 Act and the 1933 Act Regulations; the
         Indenture and the Statements of Eligibility on Form T-1 with respect to

         requirements of the 1939 Act and the 1939 Act Regulations.

         schedules therein, as to which such counsel need express no opinion),
         when they were filed with the Commission complied as to form in all
         material respects with the requirements of the 1934 Act and the 1934
         Act Regulations.

         requirements for use of Form S-3 under the 1933 Act Regulations.

         authorized, executed and delivered by the Company and qualified under
         the 1939 Act and, assuming due authorization, execution and delivery
         thereof by the Trustee, constitutes a valid and legally binding

         to the Original Secured Indenture has been duly and validly authorized,

         Company, enforceable in accordance with its terms, except as the
         enforcement thereof may be limited by the Bankruptcy Exceptions.

                                 (xx)    Each of the Remarketing Agreements has
         been validly authorized, executed and delivered by the Company and will
         constitute a valid and legally binding instrument, enforceable against
         the Company in accordance with its terms, except to the extent that the

                                (xxv)    To the best of such counsel's 
         knowledge, there are no statutes or regulations that are required
         to be described in the Prospectus that are not described as required.

                                (xxvi)   To the best of such counsel's knowledge
         and information, neither the Company nor any of its subsidiaries is in
         violation of its charter or by-laws and no default by the Company or
         any subsidiary exists in the due performance or observance of any
         material obligation, agreement, covenant or condition contained in any
         contract, indenture, mortgage, loan or credit agreement, note, lease,
         or other agreement or instrument to which the Company or any of its
         subsidiaries is a party or by which it or any of them or any of their
         respective properties or assets are bound, except for violations and
         defaults that would not, singly or in the aggregate, result in a
         Material Adverse Effect.

                                (xxvii)  All descriptions in the Prospectus of
         contracts and other documents to which the Company or any of its
         subsidiaries is a party are accurate in all material respects. To the
         best of such counsel's knowledge and information, there are no
         franchises, contracts, indentures, mortgages, loan or credit
         agreements, notes, leases or other instruments required to be described
         or referred to in the Registration Statement or incorporated by
         reference as exhibits thereto other than those described or referred to
         therein or filed or incorporated by reference as exhibits thereto, and
         the descriptions thereof or references thereto are correct in all
         material respects. No default exists in the due performance or
         observance of any material obligation, agreement, covenant or condition
         contained in the Secured Indenture, any other contract, indenture,
         mortgage, agreement, note lease or other instrument so described,
         referred to, filed or incorporated by reference.

                                (xxviii) All legally required proceedings in
         connection with the authorization, issuance and validity of the
         Securities and the sale of the Securities in accordance with this
         Agreement (other than the filing of post-issuance reports, the
         non-filing of which would not render the Securities invalid), and in
         connection with the issuance and delivery to the Trustee of the
         Collateral Bonds, have been taken; and no filing with, authorization,
         approval, consent, license, order, registration, qualification or
         decree of, any court or governmental authority or agency, domestic or
         foreign (other than under the 1933 Act and the 1933 Act Regulations,
         which have been obtained, or as may be required under the securities or
         blue sky laws of the various states, as to which such counsel need
         express no opinion) is necessary or required in connection with the due
         authorization, execution and delivery of this Agreement, the
         Remarketing Agreements or the Thirty-Fifth Supplemental Indenture, or
         for the offering, issuance and sale of the Securities, the issuance and
         delivery of the Collateral Bonds, or the performance by the Company of
         its obligations in this Agreement, the Thirty-Fifth Supplemental
         Indenture, the Indenture, the Remarketing Agreements and the 
         Securities.

                                (xxix)   The Company and its subsidiaries 
         possess all licenses, franchises, permits, certificates,
         authorizations, approvals, consents, orders and other

                                      -21-

         operating rights (collectively, the "Governmental Licenses") issued by
         the Federal Energy Regulatory Commission; the State of Michigan, and
         all other federal, state, local or foreign regulatory agencies or
         bodies, governmental authorities or agencies necessary for the
         ownership or lease of the material properties owned or leased by each
         of them and for the operation of the business carried on by each of
         them as described in the Registration Statement and the Prospectus
         except where the failure to so comply would not, singly or in the
         aggregate, have a Material Adverse Effect; all such licenses,
         franchises, permits, certificates, authorizations, approvals, consents
         and orders are in full force and effect, except when the failure of
         such Governmental Licenses to be in full force and effect would not,
         singly or in the aggregate, have a Material Adverse Effect; and contain
         no unduly burdensome provisions that would interfere with the conduct
         of the business of the Company or its subsidiaries, considered as one
         enterprise and, except as otherwise set forth in the Registration
         Statement or the Prospectus, there are no legal or governmental
         proceedings pending or threatened that would result in a material
         modification, suspension or revocation thereof.

                                 (xxx)   Each of the Company and its 
         subsidiaries has good and marketable title to all material real and
         personal property owned by each of them, in each case, free and
         clear of all mortgages, pledges, liens, security interests, claims,
         restrictions or encumbrances of any kind except such as (a) are
         described in the Registration Statement and the Prospectus or (b) do
         not, singly or in the aggregate, materially affect the value of such
         property and do not materially interfere with the use made and
         proposed to be made of such property by the Company or any of its
         subsidiaries; and any real property and buildings held under lease by
         the Company, or its subsidiaries are held by them under valid,
         subsisting and enforceable leases with such exceptions as are not
         material and do not    interfere with the conduct of the business of
         the Company or such subsidiaries.

                                 (xxxi)  The Company is not an "investment
         company" or an entity under the "control" of an "investment company" as
         such terms are defined in the 1940 Act.

                                 (xxxii) MCN and the Company are presently
         exempt from the provisions of the Public Utility Holding Company Act of
         1935 (except Section 9 thereof) which would otherwise require either of
         them to register 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 Rule
         430A Information and Rule 434 Information (if applicable)(except for
         financial statements and the notes thereto, the financial schedules
         and any other financial data included or incorporated by reference
         therein, as to which such counsel need express no opinion), at the time
         such Registration Statement became effective or at the date of this
         Agreement, contained an untrue statement of a material fact or omitted
         to state a material fact required to be stated therein or necessary to
         make the

                                      -22-

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

                  (2) The favorable opinion, dated as of the Closing Date, of
Skadden, Arps, Slate, Meagher & Flom LLP, special counsel to the Company, in
form and substance satisfactory to counsel for the Underwriters, together with
signed or reproduced copies of such letter for each of the other Underwriters,
to the effect that:

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

                                 (ii)  The Registration Statement, including any
         Rule 462(b) Registration Statement, the Rule 430A Information and the
         Rule 434 Information, as applicable, the Prospectus, excluding the
         documents incorporated by reference therein, and each amendment or
         supplement to the Registration Statement and Prospectus, excluding the
         documents incorporated by reference therein, as of their respective
         effective or issue dates (other than the financial statements and
         supporting schedules included therein, as to which such counsel need
         express no opinion), complied as to form in all material respects with
         the requirements of the 1933 Act and the 1933 Act Regulations.

                                 (iii) The statements in the Prospectus under
         the captions "Description of the Senior Debt Securities" and
         "Description of the First Mortgage Bonds," to the extent that they
         involve matters of law, summaries of legal matters, documents or
         proceedings, or legal conclusions, have been reviewed by such counsel
         and are correct in all material respects.

                                 (iv)  Assuming that the Remarketing Agreements
         being delivered at the Closing Date have been duly authorized, executed
         and delivered by the Company under Michigan law, each of them is a
         valid and legally binding agreement of the Company, enforceable against
         the Company in accordance with its terms except to the extent that the
         enforcement thereof may be limited by the Bankruptcy Exceptions.

                                 (v)   The Securities, the Indenture and the

         or the issuance and delivery to the Trustee by the Company of the
         Collateral Bonds, or the performance by the Company of its obligations

         and made under the federal securities laws or such as may be required
         under the securities or blue sky laws of the various states, as to
         which such counsel need express no opinion.

                                 Moreover, such counsel shall confirm that
         nothing has come to such counsel's attention that would lead such
         counsel to believe that the Registration Statement, including any Rule
         430A Information and Rule 434 Information (if applicable)(except for
         financial statements and the notes thereto, the financial schedules and
         any other financial data included or incorporated by reference therein,
         as to which such counsel need express no opinion), at the time such

LeBoeuf, Lamb, Greene & MacRae, L.L.P., counsel for the Underwriters, together
with signed or reproduced copies of such letter for each of the Underwriters, in
form and substance satisfactory to the Representatives, with respect to such

delivered in accordance with Section 5(b)(1) hereof.

                  (4) The opinion, dated as of the Closing Date, of Skadden,

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

         Quarterly Reports on Form 10-Q incorporated by reference in the
         Registration Statement and the Prospectus, as amended or supplemented,
         for the periods specified in such letter, a reading of the latest

         of the Company and its subsidiaries responsible for financial and
         accounting matters and such other inquiries and procedures as may be
         specified in such letter, nothing came to their attention that caused
         them to believe that:

                           (A) the unaudited condensed consolidated financial
                  statements set forth in the Company's Quarterly Reports on
                  Form 10-Q incorporated by reference in the Registration
                  Statement and the Prospectus as amended or supplemented do not

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

                           (B) any other unaudited income statement data and
                  balance sheet items included in the Prospectus, as amended or
                  supplemented, do not agree with the corresponding items in the
                  unaudited consolidated financial statements from which such
                  data and items were derived;

                  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 and the 1934 Act and the 1934 Act Regulations or
                  the pro forma adjustments have not been properly applied to
                  the historical amounts in the compilation of those statements;

                  prior to the date of this Agreement, there has been any

                  substantially consistent with the audited consolidated
                  financial statements incorporated by reference in the
                  Registration Statement and the Prospectus, as amended or
                  supplemented.

                  (iv) 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, as amended or supplemented, 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;

                  (v)  In addition to the limited procedures, reading of
         minutes, 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 and financial 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 and financial records of the Company and its
         subsidiaries and have found them to be in agreement; and

                  (vi) If applicable and agreed to by the parties to this
         Agreement, they have made a review in accordance with standards
         established by the American Institute of Certified Public Accountants
         of the selected financial data, pro forma financial information,
         prospective financial statements, consolidating financial statements
         and/or

         condensed financial statements derived from audited financial
         statements of the Company for the periods specified in such letter, as
         indicated in their reports thereon, copies of which have been furnished
         to the Representatives.

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

         (f) On the Closing Date, the Securities shall be rated at least "A2" by
Moody's Investors Service Inc. and "A" by Standard & Poor's Ratings Group, a
division of McGraw- Hill, Inc.; and the Company shall have delivered to the
Representatives a letter, dated the Closing Date, from such rating agencies, in
form satisfactory to the Representatives, confirming that the Securities have
such ratings; and since the date of this Agreement there shall not have occurred
any decrease in the ratings of any of the securities of the Company or of the
Securities by any "nationally recognized statistical rating organization" (as
defined for purposes of Rule 436(g) under the 1933 Act Regulations) and no such
organization shall have publicly announced that it has under surveillance or
review, with possible negative implications, its rating of any of the securities
of the Company or of the Securities.

         (g) On the Closing Date, counsel for the Underwriters shall have been
furnished with such documents and opinions as they may require for the purpose
of enabling them to pass upon the issuance and sale of the Securities as herein
contemplated, or in order to evidence the accuracy of any of the representations
or warranties, or the fulfillment of any of the conditions herein contained; and
all proceedings taken by the Company in connection with the issuance and sale of
the Securities as herein contemplated shall be satisfactory in form and
substance to the Representatives and counsel for the Underwriters.

         If any condition specified in this Section shall not have been
fulfilled when and as required to be fulfilled, this Agreement, may be
terminated by the Representatives by notice to the Company at any time on or
prior to the Closing Date, and such termination shall be without liability of
any party to any other party except as provided in Section 4 and except that
Sections 1, 6, 7 and 8 shall survive any such termination and remain in full
force and effect.

         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 or Section 20 of the 1934 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 Rule
         430A Information and the Rule 434 Information, if applicable, or the
         omission or alleged

                                      -28-




<PAGE>   29



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

             (iii) against any and all expense whatsoever, as incurred
         (including, the fees, expenses 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 this foregoing indemnity agreement shall not apply to
any loss, liability, claim, damage or expense to the extent arising out of any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter through Merrill Lynch expressly for use in the
Registration Statement (or any amendment thereto), including the Rule 430A
Information and the Rule 434 Information, if applicable, or any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto); provided,
further, that such indemnity with respect to the preliminary prospectus shall
not inure to the benefit of the Underwriters (or any person controlling such
Underwriters) from whom the person asserting any such loss, liability, claim,
damage or expense purchased any of the Securities which are the subject thereof
if such person did not receive a copy of the 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 in any case where the
Company complied with its obligations under Sections 3(e) and 3(g) hereof and
any such untrue statement or omission or alleged untrue statement or omission of
a material fact contained in such preliminary prospectus (or any amendment or
supplement thereto) was corrected in the 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 or Section 20 of the






                                      -29-
<PAGE>   30



1934 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, 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 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
hereunder to the extent it is not materially prejudiced as a result thereof and
in any event shall not relieve it from any liability which it may have otherwise
than on account of this indemnity agreement. In the case of parties indemnified
pursuant to Section 6(a) above, counsel to the indemnified parties shall be
selected by Merrill Lynch, and, in the case of parties indemnified pursuant to
Section 6(b) above, counsel to the indemnified parties shall be selected by the
Company. An indemnifying party may participate at its own expense in the defense
of any such action; provided, however, that counsel to the indemnifying party
shall not (except with the consent of the indemnified party) also be counsel to
the indemnified party. In no event shall the indemnifying parties be liable for
fees and expenses of more than one counsel (in addition to any local counsel)
separate from their own counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances. No
indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever in
respect of which indemnification or contribution could be sought under this
Section 6 or Section 7 hereof (whether or not the indemnified parties are actual
or potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

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

         SECTION 7. Contribution. If the indemnification provided for in Section
6 hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the 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 Company 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 the Company 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
pursuant to this Agreement (before deducting expenses) received by the Company
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 Company 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 Company or by the Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

         The Company 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

                                      -31-




<PAGE>   32



any damages which such Underwriter has otherwise been required to pay by reason
of any such untrue or alleged untrue statement or omission or alleged omission.

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

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

         SECTION 8. Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement, or contained in certificates of officers of the Company or any of its
subsidiaries submitted pursuant hereto, shall remain operative and in full force
and effect, regardless of any termination or cancellation of this Agreement or
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 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 on or prior to the Closing Date, if (i) there has been,
since the date of this Agreement or since the respective dates as of which
information is given in the Prospectus, any material adverse change or any
development which could reasonably be expected to result in a 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, 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 Representatives, impracticable to
market the Securities or to enforce contracts for the sale of the Securities, or
(iii) if trading in any securities of the Company or any of its affiliates has
been suspended or limited by the Commission, the National Association of
Securities Dealers, Inc. ("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


                                      -32-




<PAGE>   33



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 is terminated pursuant to this Section 9, such
termination shall be without liability of any party to any other party except as
provided in Section 4, and provided, further, that Sections 1, 6, 7 and 8 shall
survive such termination and remain in full force and effect.

         SECTION 10. Default by One or More of the Underwriters. If one or more
of the Underwriters shall fail at the Closing Date to purchase the Securities
which it or they are obligated to purchase under this 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 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, 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
number of Securities to be purchased on such date, each of 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 of Defaulted Securities exceeds 10% of the number of
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 Representatives or the Company shall have the
right to postpone the Closing Date 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. As used herein, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 10.

         SECTION 11. Notices. All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication. Notices to the
Underwriters shall be directed to the Representative at North Tower, World
Financial Center, New York, New York 10281-1202, attention of Karl Fritz Schlopy

         SECTION 12. Parties. This Agreement shall inure to the benefit of and
be binding upon the Company, and the Underwriters and their respective
successors. Nothing expressed or mentioned in this Agreement is intended or
shall be construed to give any person, firm or corporation, other than the
Underwriters, the Company and their respective successors and the controlling
persons and officers and directors referred to in Sections 6 and 7 and their
heirs and legal representatives, any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision herein or therein
contained. This Agreement and all conditions and provisions hereof and thereof
are intended to be for the sole and exclusive benefit of the parties hereto and
thereto and their respective successors and legal representatives, and said
controlling persons and officers and directors and their heirs and legal

purchaser of 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 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

                                due June 30, 2038

         1. Indenture. (a) This Extendable MOPPRS is one of the duly authorized
issue of securities of the Company (hereinafter called the "Notes") of the
series hereinafter specified, all issued or to be issued under and pursuant to
an Indenture, dated as of June 1, 1998, as supplemented by the first
supplemental Indenture, dated as of June 18, 1998 between the Company and the
Trustee (as so supplemented, the "Senior Indenture"), duly executed and
delivered by the Company to Citibank, N.A., as Trustee (herein called the
"Senior Trustee," which term includes any successor trustee under the Senior
Indenture), to which Senior Indenture reference is hereby made for a description
of the rights, limitations of rights, obligations, duties and immunities
thereunder of the Senior Trustee, the Company and the Holders of the Notes. The
Notes may be issued in one or more series, which different series may be issued
in various aggregate principal amounts, may mature at different times, may bear
interest, if any, at different rates, may be subject to different redemption
provisions (if any) and may be subject to different sinking, purchase or
analogous funds (if any) and may otherwise vary as provided in the Indenture.
This Note is one of the series designated as the Extendable MandatOry Par Put
Remarketed Notes(sm) ("MOPPRS(sm)") due June 30, 2038 of the Company, which 
series is limited in aggregate principal amount to $75,000,000.

         (b) Interest shall be computed on the basis of a 360-day year of twelve
30-day months. The Company shall pay interest on overdue principal and, to the
extent lawful, on overdue installments of interest at the rate per annum borne
by this Note. For purposes hereof, the term "Business Day" means any day other
than a Saturday or Sunday or a day on which banking institutions in The City of
New York are required or authorized to close and, in the case of Notes in Reset
Mode that are in the Floating Rate Interest Mode that is also a London Business
Day. "London Business Day" means any day on which dealings in deposits in U.S.
dollars are transacted on the London interbank market.

         (c) Unless otherwise defined herein, all capitalized terms used herein
without definition shall have the meanings assigned to them in the Senior
Indenture.

         2. Terms of the Notes in Mandatory Tender Mode. On the date, if any, on
which the Mandatory Tender Remarketing Agent elects to exercise the Remarketing
Right in accordance with the terms hereof, the Notes shall be deemed to be in
"Mandatory Tender Mode."

         (a) Mandatory Tender on First Remarketing Date; Purchase and
Settlement. (i) Provided that the Mandatory Tender Remarketing Agent gives
notice to the Company and the Senior Trustee on a Business Day not later than
eleven Business Days prior to the First Remarketing Date of its intention to
exercise the Remarketing Right to purchase the Notes for remarketing (the
"Mandatory Tender Notification Date"), each Note shall be automatically
tendered, or deemed tendered, to the Mandatory Tender Remarketing Agent for
purchase on the Mandatory Tender Remarketing Date in accordance with Section
2(a)(ii) below, except as set forth in Sections 6 and

                                       -5-

7 below. The purchase price of such tendered Notes shall be equal to
100% of the principal amount thereof. Upon such tender, the Mandatory Tender
Remarketing Agent shall have the option, in its sole discretion, to elect to
remarket the Notes in accordance with the Mandatory Tender Remarketing Agreement
for its own account at varying prices to be determined by the Mandatory Tender
Remarketing Agent at the time of each sale. If the Mandatory Tender Remarketing
Agent makes such election, the obligation of the Mandatory Tender Remarketing
Agent to purchase the Notes on the Mandatory Tender Remarketing Date shall be
subject to the conditions set forth in the Mandatory Tender Remarketing
Agreement. No Holder or actual purchaser of the Notes ("Beneficial Owner") shall
have any rights or claims under the Mandatory Tender Remarketing Agreement or
against the Company or the Mandatory Tender Remarketing Agent as a result of the
Mandatory Tender Remarketing Agent not purchasing such Notes.

         (i) Following the Mandatory Tender Notification Date and assuming that
the Notes are remarketed by the Mandatory Remarketing Agent pursuant to the
exercise of the Remarketing Right, the tender and purchase of the Notes provided
for in Section 2(a)(i) above shall be effected as follows, subject to Sections 6
and 7 below:

                  (x) All of the tendered Notes shall be automatically delivered
         to the account of the Trustee, by book-entry through DTC or any
         successor thereto pending payment of the purchase price therefor, on
         the Remarketing Date.

                  (y) The Mandatory Tender Remarketing Agent shall make or cause
         the Trustee to make payment to DTC by book entry through DTC in
         accordance with the procedures of DTC, by 1:00 p.m., New York City
         time, on the Mandatory Tender Remarketing Date against delivery through
         DTC of such Beneficial Owner's tendered Notes, of the purchase price
         for tendered Notes that have been purchased for remarketing by the
         Mandatory Tender Remarketing Agent. The Company shall make or cause the
         Trustee to make payment of interest to DTC on the Mandatory Tender
         Remarketing Date by book entry through DTC by 2:30 p.m., New York City
         time, on the Mandatory Tender Remarketing Date.

             (ii) In anticipation of the purchase of the Notes by the Mandatory
         Tender Remarketing Agent for remarketing or the repurchase of the Notes
         by the Company on the Remarketing Date, the Trustee shall notify the
         Holder hereof, not less than 30 days nor more than 60 days prior to the
         Remarketing Date, that all Notes will be delivered on the Mandatory
         Tender Remarketing Date through the facilities of DTC against payment
         of the purchase price therefor by the Mandatory Tender Remarketing
         Agent or the Company, as the case may be.

         (b) Determination of Interest Rate to Second Remarketing Date;
Notification Thereof. Subject to the Remarketing Dealer's election to exercise
the Remarketing Right as provided in Section 2(a)(i), by 3:30 p.m., New York
City time, on the third Business Day immediately preceding the Remarketing Date
(the "Mandatory Tender Determination Date"), the Mandatory Tender Remarketing
Agent shall determine the Interest Rate to Second Remarketing Date to the
nearest one hundred-thousandth (0.00001) of one percent per annum. The Interest
Rate to

                                       -6-

<PAGE>   15


Second Remarketing Date shall be equal to the sum of 5.50% (the "Base
Rate") and the Applicable Spread (as defined below), which will be based on the
Dollar Price (as defined below) of the Notes.

         The "Applicable Spread" for the Notes in Mandatory Tender Mode shall be
the lowest bid indication, expressed as a spread (in the form of a percentage or
in basis points) above the Base Rate, obtained by the Mandatory Tender
Remarketing Agent on the Mandatory Tender Determination Date from the bids
quoted by five Reference Corporate Dealers (as defined below) for the full
aggregate principal amount of the Notes at the Dollar Price, but assuming (i) an
issue date that is the Mandatory Tender Remarketing Date, with settlement on
such date without accrued interest, (ii) a maturity date that is the Second
Remarketing Date of the Notes and (iii) a stated annual interest rate, payable
semiannually on each Interest Payment Date (as defined below), equal to the Base
Rate plus the spread bid by the applicable Reference Corporate Dealer Second
Remarketing Date. If fewer than five Reference Corporate Dealers bid as
described above, then the Applicable Spread shall be the lowest of such bid
indications obtained as described above. The Interest Rate to Second Remarketing
Date announced by the Mandatory Tender Remarketing Agent, absent manifest error,
shall be binding and conclusive upon the Beneficial Owners and Holders of the
Notes, the Company and the Senior Trustee.

         "Dollar Price" means, with respect to the Notes in Mandatory Tender
Mode, the present value determined by the Mandatory Tender Remarketing Agent, as
of the First Remarketing Date, of the Remaining Scheduled Payments (as defined
below) discounted to the First Remarketing Date on a semiannual basis (assuming
a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as
defined below).

         "Reference Corporate Dealers" means leading dealers of publicly traded
debt securities of the Company in The City of New York (which may include the
Mandatory Tender Remarketing Agent or one of its affiliates) selected by the
Mandatory Tender Remarketing Agent after consultation with the Company.

         "Remaining Scheduled Payments" means, with respect to the Notes, the
remaining scheduled payments of the principal thereof and interest thereon,
calculated at the Applicable Base Rate only, that would be due after the First
Remarketing Date to and including the Second Remarketing Date as determined by
the Mandatory Tender Remarketing Agent.

         "Treasury Rate" means, with respect to the First Remarketing Date, the
rate per annum equal to the semiannual equivalent yield to maturity or
interpolated (on a day count basis) yield to maturity of the Comparable Treasury
Issues (as defined below), assuming a price for the Comparable Treasury Issues
(expressed as a percentage of its principal amount), equal to the Comparable
Treasury Price (as defined below) for such Remarketing Date.

         "Comparable Treasury Issues" means the United States Treasury Security
or Securities selected by the Mandatory Tender Remarketing Agent as having an
actual or interpolated maturity or maturities comparable to the Second
Remarketing Date.

                                       -7-

<PAGE>   16

         "Comparable Treasury Price" means, with respect to the First
Remarketing Date, (a) the offer prices for the Comparable Treasury Issues
(expressed in each case as a percentage of its principal amount) on the
Mandatory Tender Determination Date, as set forth on "Telerate Page 500" (or
such other page as may replace Telerate Page 500) or (b) if such page (or any
successor page) is not displayed or does not contain such offer prices on such
Mandatory Tender Determination Date, (i) the average of the Reference Treasury
Dealer Quotations for the First Remarketing Date, after excluding the highest
and lowest of such Reference Treasury Dealer Quotations, or (ii) if the
Mandatory Tender Remarketing Agent obtains fewer than four such Reference
Treasury Dealer Quotations, the average of all such Reference Treasury Dealer
Quotations. "Telerate Page 500" means the display designated as "Telerate Page
500" on Dow Jones Markets Limited (or such other page as may replace Telerate
Page 500 on such service) or such other service displaying the offer prices
specified in (a) above as may replace Dow Jones Markets Limited.

         "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and the First Remarketing Date, the offer prices for
the Comparable Treasury Issues (expressed in each case as a percentage of its
principal amount) quoted to the Remarketing Dealer by such Reference Treasury
Dealer by 3:30 p.m., New York City time, on the First Determination Date.

         "Reference Treasury Dealer" means each of Credit Suisse First Boston
Corporation, Lehman Brothers Inc., Merrill Lynch, Pierce, Fenner & Smith

their respective successors; provided, however, that if any of the foregoing or
their affiliates shall cease to be a primary U.S. Government Notes dealer in The
City of New York (a "Primary Treasury Dealer"), the Remarketing Dealer shall
substitute therefor another Primary Treasury Dealer.

         Provided the Remarketing Right has been exercised, the Mandatory Tender
Remarketing Agent shall notify the Company, the Senior Trustee and DTC by
telephone, confirmed in writing, by 4:00 p.m., New York City time, on the
Mandatory Tender Determination Date, of the Interest Rate to Second Remarketing
Date. In such event, all of the tendered Notes of a series will be automatically
delivered to the account of the Senior Trustee, by book-entry through DTC
pending payment of the purchase price therefor, on the First Remarketing Date,
and the Mandatory Tender Remarketing Agent shall make or cause the Senior
Trustee to make payment to the DTC Participant of each tendering Beneficial
Owner of the Notes, by book-entry through DTC by the close of business on the
First Remarketing Date against delivery through DTC of such Beneficial Owner's
tendered Notes of 100% of the principal amount of such tendered Notes. The
transactions described above shall be executed on the First Remarketing Date
through DTC in accordance with the procedures of DTC, and the accounts of the
respective DTC Participants shall be debited and credited and the Notes
delivered by book entry as necessary to effect the purchases and sales thereof.
Transactions involving the sale and purchase of the Notes remarketed by the
Mandatory Tender Remarketing Agent on and after the First Remarketing Date shall
settle in immediately available funds through DTC's Same-Day Funds Settlement
System. The tender and settlement procedures described above, including

                                       -8-

<PAGE>   17



provisions for payment by purchasers of the Notes in the remarketing or
for payment to selling Beneficial Owners of tendered Notes, may be modified to
the extent required by DTC or to the extent required to facilitate the tender
and remarketing of such series of Notes in certificated form, if the book-entry
system is no longer available for the Notes at the time of the remarketing. In
addition, the Mandatory Tender Remarketing Agent may, in accordance with the
terms of the Senior Indenture, modify the tender and settlement procedures set
forth above in order to facilitate the tender and settlement process.

         3. Terms of the Notes in Reset Mode. If (i) the Mandatory Tender
Remarketing Agent does not provide notification to the Company of its intention
to exercise the Remarketing Right on the eleventh Business Day prior to the
First Remarketing Date (which date may also be referred to herein as the
"Mandatory Tender Remarketing Date"), on the tenth Business Day prior to the
Mandatory Tender Remarketing Date or (ii) the Second Remarketing Date, in the
event the Remarketing Right is exercised, the Notes will be deemed to be in
"Reset Mode."

         (a) Tender at Option of Beneficial Owners in Reset Mode. If the Company
and the Reset Remarketing Agent agree on the Spread on the Spread Determination
Date (as defined below) with respect to any Subsequent Spread Period, the
Company and the Reset Remarketing Agent will enter into a Reset Remarketing
Agreement Supplement (a "Reset Remarketing Agreement Supplement") under which
the Reset Remarketing Agent will agree, subject to Section 6 and 7 below and
other applicable terms and conditions set forth in such Reset Remarketing
Agreement Supplement, to purchase from tendering Holders on the Reset Tender
Date all Notes with respect to which the Reset Remarketing Agent receives a
Reset Tender Notice as described below at 100% of the principal amount thereof
(the "Purchase Price"). Except as otherwise provided in the next succeeding
paragraph, each Beneficial Owner of a Note may, at such owner's option, upon
giving notice as provided below (a "Reset Tender Notice"), tender such Note for
purchase by the Reset Remarketing Agent on the Reset Tender Date with respect to
a Spread Period at the Purchase Price. The Purchase Price shall be paid by the
Reset Marketing Agent in accordance with the standard procedures of DTC, and
accounts of the respective DTC Participants shall be debited and credited and
the Notes delivered by book-entry as necessary to effect any purchases and sales
thereof.

         The Reset Tender Notice must be received by the Reset Remarketing Agent
during the period commencing at 3:00 p.m., New York City time, on the Spread
Determination Date and ending at 12:00 noon, New York City time, on the second
Business Day following such Spread Determination Date for such Subsequent Spread
Period (the "Notice Date"). Except as otherwise provided below, a Reset Tender
Notice shall be irrevocable. If a Reset Tender Notice is not received for any
reason by the Reset Remarketing Agent with respect to any Note by 12:00 noon,
New York City time, on the Notice Date, the Beneficial Owner of such Note shall
be deemed to have elected not to tender such Note for purchase by the Reset
Remarketing Agent.

         (b) Determination of Duration and Interest Rate Mode. Upon each
Duration/Interest Mode Determination Date (as defined below), the mode and other
terms for the next Subsequent Spread Period shall be determined as described
below.

                                       -9-

<PAGE>   18

             (i) Floating Rate Interest Mode. If the Notes in Reset Mode are in
         Floating Rate Mode, then the following shall apply: During the Floating
         Rate Interest Mode, interest on the Notes for each Subsequent Spread
         Period shall be payable either monthly, quarterly or semiannually, as
         specified by the Company on each Duration/Interest Mode Determination
         Date. With respect to Notes in the Floating Rate Interest Mode,
         interest shall be payable, in arrears, in the case of Notes which pay:
         (a) monthly, on the thirtieth day of each month; (b) quarterly, on the
         thirtieth day of each March, June, September and December; and (c)
         semiannually, on the thirtieth day of each June and December. During
         any Subsequent Spread Period during which the Reset Mode Notes are in
         the Floating Rate Interest Mode, the interest rate on the Notes shall
         be reset either monthly, quarterly or semiannually, and the Notes shall
         bear interest at a per annum rate (computed on the basis of the actual
         number of days elapsed over a 360-day year) equal to LIBOR (as defined
         below) for the applicable Interest Period (as defined below), plus the
         applicable Spread. Interest on the Notes shall accrue from and
         including each Interest Payment Date to but excluding the next
         succeeding Interest Payment Date or maturity date, as the case may be.
         Each interest period during any Subsequent Spread Period (each, an
         "Interest Period") shall be from and including the most recent Interest
         Payment Date on which interest has been paid to but excluding the next
         Interest Payment Date. The first day of an Interest Period is referred
         to herein as an "Interest Reset Date".

             If any Interest Payment Date (other than at maturity), redemption
         date, Interest Reset Date, Duration/Interest Mode Determination Date,
         Spread Determination Date (as defined below), Commencement Date or
         Reset Tender Date would otherwise be a day that is not a Business Day,
         such Interest Payment Date, redemption date, Interest Reset Date,
         Duration/Interest Mode Determination Date, Spread Determination Date,
         Commencement Date or Reset Tender Date, as the case may be, shall be
         postponed to the next succeeding day that is a Business Day; provided,
         however, that if such next succeeding Business Day is in the next
         calendar month, such date shall occur on the immediately preceding
         Business Day.

             LIBOR applicable for an Interest Period shall be determined by the
         Rate Agent (as defined below) as of the second London Business Day (as
         defined below) preceding each Interest Reset Date (a "LIBOR
         Determination Date") in accordance with the following provisions:

                 (x) LIBOR shall be determined on the basis of the offered rate
             for deposits in U.S. Dollars of the applicable Index Maturity
             commencing on the second London Business Day immediately following
             such LIBOR Determination Date, which appears on Telerate Page 3750
             (as defined below) as of approximately 11:00 a.m., London time, on
             such LIBOR Determination Date. "Telerate Page 3750" means the
             display designated on page "3750" on Dow Jones Markets Limited or
             any successor thereto (or such other page as may replace the 3750
             page on that service or such other service or services as may be
             nominated by the British Bankers' Association for the purpose of
             displaying London interbank offered rates for U.S. Dollar
             deposits). If no such offered rate appears on Telerate Page 3750,
             LIBOR for such LIBOR Determination Date shall

                                      -10-

<PAGE>   19



             be determined in accordance with the provisions of paragraph (y)
             below. The term "London Business Day" means any day on which
             dealings in deposits in U.S. Dollars are transacted in the London
             interbank market.

                  (y) With respect to a LIBOR Determination Date on which no
             rate appears on Telerate Page 3750 as of approximately 11:00 a.m.,
             London time, on such LIBOR Determination Date, the Rate Agent shall
             request the principal London offices of each of four major
             reference banks in the London interbank market selected by the Rate
             Agent (after consultation with the Company) to provide the Rate
             Agent with a quotation of the rate at which deposits in U.S.
             Dollars of the applicable Index Maturity commencing on the second
             London Business day immediately following such LIBOR Determination
             Date, are offered by it to prime banks in the London interbank
             market as of approximately 11:00 a.m., London time, on such LIBOR
             Determination Date and in a principal amount equal to an amount of
             not less than U.S. $1,000,000 that is representative for a single
             transaction in such market at such time. If at least two such
             quotations are provided, LIBOR for such LIBOR Determination Date
             shall be the arithmetic mean of such quotations as calculated by
             the Rate Agent. If fewer than two quotations are provided, LIBOR
             for such LIBOR Determination Date shall be the arithmetic mean of
             the rates quoted as of approximately 11:00 a.m., New York City
             time, on such LIBOR Determination Date by three major banks in The
             City of New York selected by the Rate Agent (after consultation
             with the Company) for loans in U.S. Dollars to leading European
             banks, of the applicable Index Maturity commencing on the second
             London Business Day immediately following such LIBOR Determination
             Date and in a principal amount equal to an amount of not less than
             U.S. $1,000,000 that is representative for a single transaction in
             such market at such time; provided, however, that if the banks
             selected as aforesaid by the Rate Agent are not quoting as
             mentioned in this sentence, LIBOR for such LIBOR Determination Date
             shall be LIBOR determined with respect to the immediately preceding
             LIBOR Determination Date.

             The Index Maturity applicable to Notes in the Floating Rate
         Interest Mode shall be, in the case of Notes paying (x) monthly, one
         month; (y) quarterly, three months; and (z) semiannually, six months.

             The term "Rate Agent" means the entity selected by the Company as
         its agent to determine (i) LIBOR and the interest rate on the Notes for
         any Interest Period and/or (ii) the yield to maturity on the applicable
         United States Treasury security that is used in connection with the
         determination of the applicable Fixed Rate, and the ensuing applicable
         Fixed Rate pursuant to the Reset Remarketing Agreement.

             (ii) Fixed Rate Interest Mode. If the Notes are to be reset to the
         Fixed Rate Interest Mode, as agreed to by the Company and the Reset
         Remarketing Agent on a Duration/Interest Mode Determination, then the
         applicable Fixed Rate for the corresponding Subsequent Spread Period
         shall be determined by 1:00 p.m. on the third Business Day preceding
         the Commencement Date for such Subsequent Spread Period 


                                      -11-

<PAGE>   20


         (the "Fixed Rate Determination Date"), in accordance with the following
         provisions: the Fixed Rate shall be a per annum rate and shall be
         determined by auditing the applicable Spread (as agreed to by the
         Company and the Reset Remarketing Agent on the preceding Spread
         Determination Date) to the yield to maturity (expressed as a bond
         equivalent, on the basis of a year of 365 or 366 days, as applicable,
         and applied on a daily basis) of the applicable United States Treasury
         security, selected by the Rate Agent or its agent after consultation
         with the Reset Remarketing Agent, as having a maturity comparable to
         the duration selected for the following Subsequent Spread Period, which
         would be used in accordance with customary financial practice in
         pricing new issues of corporate debt securities of comparable maturity
         to the duration selected for the following Subsequent Spread Period.

             Interest in the Fixed Rate Interest Mode shall be computed on the
         basis of a 360-day year of twelve 30-day months. Such interest shall be
         payable semiannually in arrears on the Interest Payment Dates occurring
         on each June 30 and December 30 at the applicable Fixed Rate, as
         determined by the Company and the Reset Remarketing Agent on the Fixed
         Rate Determination Date, beginning on the Commencement Date and for the
         duration of the relevant Subsequent Spread Period. Interest on the
         Notes shall accrue from and including each Interest Payment Date to but
         excluding the next succeeding Interest Payment Date or maturity date,
         as the case may be.

         If any Interest Payment Date or any redemption date in the Fixed Rate
Interest Mode falls on a day that is not a Business Day (in either case, other
than any Interest Payment Date or redemption date that falls on a Commencement
Date, in which case each such date including the Commencement Date shall be
postponed to the next day that is a Business Day), the related payment of
principal and interest shall be made on the next succeeding Business Day as if
it were made on the date such payment was due, and no interest shall accrue on
the amounts so payable for the period from and after such dates; provided,
however, that if such next succeeding Business Day is in the next calendar year,
such Interest Payment Date shall occur on the immediately preceding Business
Day.

         (c) Additional Terms of the Notes in Reset Mode. The Spread that shall
be applicable during each Subsequent Spread Period for Notes in Reset Mode shall
be the percentage (a) recommended by the Reset Remarketing Agent so as to result
in a rate that, in the opinion of the Reset Remarketing Agent, will enable
tendered Notes to be remarketed by the Reset Remarketing Agent at 100% of the
principal amount thereof, and (b) agreed to by the Company. The interest rate
mode during such Subsequent Spread Period shall be either the Floating Rate
Interest Mode or the Fixed Rate Interest Mode, as determined by the Company and
the Reset Remarketing Agent.

         Unless notice of redemption of the Notes as a whole has been given, the
duration, redemption dates, redemption type, redemption prices (if applicable),
Commencement Date, Interest Payment Dates and interest rate mode (and any other
relevant terms) for each Subsequent Spread Period shall be established by 3:00
p.m., New York City time, on the tenth Business Day prior to the Commencement
Date of each Subsequent Spread Period (each a "Duration/Interest

                                      -12-

<PAGE>   21



Mode Determination Date"). In addition, the Spread for each Subsequent
Spread Period shall be established by 1:00 p.m., New York City time, on the
fifth Business Day prior to the Commencement Date of such Subsequent Spread
Period (each, a "Spread Determination Date"). Thirty calender days prior to the
First Remarketing Date, the Company shall request that DTC provide preliminary
notification to its Participants that, on the date that is ten Business Days
prior to the First Remarketing Date either (i) the Remarketing Right will have
been exercised and the Notes will be subject to mandatory tender on the First
Remarketing Date or (ii) the Notes will be in Reset Mode and a Duration/Interest
Mode Determination Date will occur on such date. If the Mandatory Tender
Remarketing Agent does not provide notification of its intention to exercise the
Remarketing Right on the Mandatory Tender Notification Date, on or before the
date that is ten Business Days prior to the First Remarketing Date, the Company
shall request that DTC notify its Participants of the occurrence of a
Duration/Interest Mode Determination Date and of the procedures that must be
followed if any Beneficial Owner of a Note wishes to tender such Note. With
respect to all Subsequent Spread Periods established after the First Remarketing
Date, the Company shall request not later than five nor more than ten calendar
days prior to any Duration/Interest Mode Determination Date, that DTC notify its
Participants of such Duration/Interest Mode Determination Date and of the
procedures that must be followed if any Beneficial Owner of a Notes wishes to
tender such Note. In the event that DTC or its nominee is no longer the Holder
of record of the Notes, the Company shall notify the Holders of such information
within such period of time.

         In the event that the Company and the Reset Remarketing Agent do not
agree on the Spread for any Subsequent Spread Period, then the Company shall be
required unconditionally to repurchase and retire all of the Notes on the Reset
Tender Date at a price equal to 100% of the principal amount thereof, together
with accrued interest to the Reset Tender Date. In the event that the Reset
Remarketing Agent fails to purchase any Notes tendered on the Reset Tender Date,
then the Company shall be required unconditionally to repurchase and retire any
Notes tendered and not purchased by the Reset Remarketing Agent.

         All percentages resulting from any calculation of any interest rate for
the Notes shall be rounded, if necessary, to the nearest one hundred thousandth
of a percentage point, with five one millionths of a percentage point rounded
upward, and all dollar amounts shall be rounded to the hearest cent, with
one-half cent being rounded upward.

         4. Security; Release Date. Prior to the Release Date (as hereinafter
defined), the Notes shall be secured by First Mortgage Bonds designated as
Collateral Bonds, Series A (the "Collateral Bonds"), delivered by the Company to
the Senior Trustee for the benefit of the Holders of the Notes. Prior to the
Release Date, the Company shall make payments of the principal of, and premium,
if any, and or interest on, the Collateral Bonds to the Senior Trustee, which
payments shall be applied by the Senior Trustee to satisfaction of all
obligations then due on the Notes. Reference is made to the Mortgage Indenture
and the Senior Indenture for a description of the rights of the Senior Trustee
as holder of the Collateral Bonds, the property mortgaged and pledged under the
Mortgage Indenture and the rights of the Company and of the Mortgage Trustee in
respect thereof, the duties and immunities of the Mortgage Trustee and the 



                                      -13-

<PAGE>   22



terms and conditions upon which the Collateral Bonds are secured and
the circumstances under which additional First Mortgage Bonds may be issued.

         FROM AND AFTER SUCH TIME AS ALL FIRST MORTGAGE BONDS (OTHER THAN
COLLATERAL BONDS) ISSUED UNDER THE MORTGAGE INDENTURE HAVE BEEN RETIRED THROUGH
PAYMENT, REDEMPTION OR OTHERWISE AT, BEFORE OR AFTER THE MATURITY THEREOF (THE
"RELEASE DATE"), THE COLLATERAL BONDS SHALL CEASE TO SECURE THE NOTES IN ANY
MANNER PROVIDED THAT NO DEFAULT OR EVENT OF DEFAULT HAS OCCURRED AND AT SUCH
TIME IS CONTINUING UNDER THE SENIOR INDENTURE. IN CERTAIN CIRCUMSTANCES PRIOR TO
THE RELEASE DATE AS PROVIDED IN THE SENIOR INDENTURE, THE COMPANY IS PERMITTED
TO REDUCE THE AGGREGATE PRINCIPAL AMOUNT OF A SERIES OF COLLATERAL BONDS HELD BY
THE TRUSTEE, BUT IN NO EVENT PRIOR TO THE RELEASE DATE TO AN AMOUNT LESS THAN
THE AGGREGATE OUTSTANDING PRINCIPAL AMOUNT OF THE SERIES OF NOTES INITIALLY
ISSUED CONTEMPORANEOUSLY WITH SUCH COLLATERAL BONDS.

         5. Maintenance of Book-Entry System. (a) The tender and settlement
procedures set forth in Section 2 above, including provisions for payment by
purchasers of Notes in the remarketing or for payment to selling Beneficial
Owners of tendered Notes, shall be subject to modification, notwithstanding any
provision to the contrary set forth in Article 9 of the Senior Indenture, to the
extent required by DTC or, if the book-entry system is no longer available for
the Notes at the time of the remarketing, to the extent required to facilitate
the tendering and remarketing of Notes in certificated form. In addition, either
of the Remarketing Agents may, notwithstanding any provision to the contrary set
forth in Article 9 of the Senior Indenture, modify the settlement procedures set
forth herein in order to facilitate the settlement process.

         (b) The Company hereby agrees with the Senior Trustee and the holders
of Notes that at all times, notwithstanding any provision to the contrary set
forth in the Senior Indenture, (i) it shall use its best efforts to maintain the
Notes in book-entry form with DTC or any successor thereto and to appoint a
successor thereto to the extent necessary to maintain the Notes in book-entry
form and (ii) it shall waive any discretionary right that it otherwise may have
under the Senior Indenture to cause the Notes to be issued in certificated form.

         6. Repurchase. If the Notes are in Mandatory Tender Mode, in the event
that (i) the Mandatory Remarketing Agent for any reason does not notify the
Company of the Interest Rate to Second Remarketing Date by 4:00 p.m., New York
City time, on the Mandatory Tender Determination Date, or (ii) prior to the
First Remarketing Date, the Mandatory Tender Remarketing Agent has resigned and
no successor has been appointed on or before the Mandatory Tender Determination
Date, or (iii) since the Mandatory Tender Notification Date, the Mandatory
Tender Remarketing Agent terminates the Mandatory Tender Remarketing Agreement
because of the occurrence of a material adverse change in the condition of the
Company and its subsidiaries, considered as one enterprise, or because an Event
of Default, or any event which, with the giving of notice or passage of time, or
both, would constitute an Event of Default, with respect to the Notes has
occurred and is continuing, or any other event 


                                      -14-

<PAGE>   23


constituting a termination event under the Mandatory Tender Remarketing
Agreement has occurred, or (iv) the Mandatory Tender Remarketing Agent for any
reason does not purchase all tendered Notes on the First Remarketing Date, the
Company shall repurchase such Notes on the First Remarketing Date at a price
equal to 100% of the principal amount of such Notes plus all accrued and unpaid
interest, if any, to the First Remarketing Date.

         If the Notes are in Reset Mode, in the event that (i) the Company and
the Reset Remarketing Agent fail for any reason to agree on a Spread for a
Subsequent Spread Period, or (ii) prior to any Commencement Date, the Reset
Remarketing Agent has resigned and no successor thereto has been appointed on or
before the Duration/Interest Mode Determination Date, or (iii) since the Spread
Determination Date, the Reset Remarketing Agent terminates the Reset Remarketing
Agreement because of the occurrence of a material adverse change in the
condition of the Company and its subsidiaries, considered as one enterprise, or
because an Event of Default, or any event which, with the giving of notice or
passage of time, or both, would constitute an Event of Default, with respect to
the Notes has occurred and is continuing, or any other event constituting a
termination event under the Reset Remarketing Agreement has occurred, or (iv)
the Reset Remarketing Agent for any reason does not purchase any Notes tendered
on the Reset Tender Date, the Company shall repurchase any such Notes tendered
but not purchased by the Reset Remarketing Agent on the First Remarketing Date
at a price equal to 100% of the principal amount of such Notes plus all accrued
and unpaid interest, if any, to the applicable Reset Tender Date.

         7. Redemption. (a) Notwithstanding any election by the Mandatory Tender
Remarketing Agent to remarket the Notes on the Mandatory Tender Remarketing
Date, the tendering of the Notes for purchase by the Mandatory Tender
Remarketing Agent on such date as set forth in Section 2(b)(ii) above shall be
subject to the right of the Company to redeem the Notes from the Mandatory
Tender Remarketing Agent as provided in Section 7(b) below.

         (b) The Company, in its sole and absolute discretion, shall have the
right, upon notice to the Mandatory Tender Remarketing Agent and the Senior
Trustee not later than the close of business on the Business Day immediately
preceding the Mandatory Tender Determination Date, to irrevocably elect to
redeem the Notes, in whole but not in part, from the Mandatory Tender
Remarketing Agent on the Mandatory Tender Remarketing Date at the Optional
Redemption Price. The "Optional Redemption Price" shall be the greater of (i)
100% of the principal amount of the Notes and (ii) the sum of the present values
of the Remaining Scheduled Payments thereon, as determined by the Mandatory
Tender Remarketing Agent, discounted to the Mandatory Tender Remarketing Date on
a semiannual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Treasury Rate, plus in either case accrued and unpaid interest from the
Mandatory Tender Remarketing Date on the principal amount being redeemed to the
date of redemption. If the Company elects to redeem the Notes, it shall pay the
redemption price therefor in same-day funds by wire transfer to an account
designated by the Mandatory Tender Remarketing Agent on the Mandatory Tender
Remarketing Date.

         (c) If the Notes are in Reset Mode, on each Commencement Date and on
those Interest Payment Dates specified as redemption dates by the Company on the
Duration/Interest Mode 



                                      -15-

<PAGE>   24


Determination Date in connection with any Subsequent Spread Period, the
Notes may be redeemed, at the option of the Company, in whole or in part, upon
notice thereof given at any time during the 30-calendar-day period ending on the
tenth Business Day prior to the redemption date (provided that notice of any
partial redemption must be given at least 15 calendar days prior to the
redemption date), in accordance with the redemption type selected on the
Duration/Interest Mode Determination date. In the event that less than all of
the outstanding Notes are to be so redeemed, the Notes to be redeemed shall be
selected by such method as the Senior Trustee shall deem fair and appropriate.

         The redemption type to be chosen by the Company and the Reset
Remarketing Agent on the Duration/Interest Mode Determination Date may be one of
the following as defined herein: (i) Par Redemption; (ii) Premium Redemption; or
(iii) Make-Whole Redemption. "Par Redemption" means redemption at a redemption
price equal to 100% of the principal amount thereof, plus accrued interest
thereon, if any, to the redemption date. "Premium Redemption" means redemption
at a redemption price or prices greater than 100% of the principal amount
thereof, plus accrued interest thereon, if any, to the redemption date, as
determined on the Duration/Interest Mode Determination date. "Make-Whole
Redemption" means redemption at a redemption price equal to the Make-Whole
Amount (as defined below), if any, with respect to such Notes. Unless otherwise
specified by the Company on any Duration/Interest Mode Determination Date, the
redemption type will be a Par Redemption.

         "Make-Whole Amount" means, in connection with any optional redemption
or accelerated payment of any Note, any amount equal to the greater of (i) 100%
of the principal amount and (ii) the sum of the present values of the remaining
scheduled payments of principal and interest thereon from the redemption date to
the end of the applicable Subsequent Spread Period, computed by discounting such
payments, in each case, to the date of redemption on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the applicable
Treasury Rate plus the Reinvestment Spread, plus accrued interest on the
principal amount thereof to the date of redemption.

         "Reinvestment Spread" means, with respect to the Notes, a number,
expressed as a number of basis points or as a percentage, selected by the
Company and agreed to by the Reset Remarketing Agent on the Duration/Interest
Mode Determination Date.

         8. Effect of Event of Default. In case an Event of Default with respect
to the Notes shall occur and be continuing, the unpaid principal of the Notes
may be declared due and payable, in the manner, with the effect and subject to
the conditions provided in the Senior Indenture.

         9. Amendments and Waivers. The Senior Indenture may be modified by the
Company and the Senior Trustee without consent of any Holder with respect to
certain matters as described in the Indenture. In addition, the Senior Indenture
permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of
the Holders of the Notes of each series to be affected under the Senior
Indenture at any time by the Company and the Senior Trustee with the consent of
the Holders of a majority in principal amount of the Notes at the time
Outstanding of each series to be affected. 


                                      -16-

<PAGE>   25



The Senior Indenture also contains provisions permitting the Holders of
a majority in principal amount of the Notes of each series at the time
Outstanding, on behalf of the Holders of all Notes of such series, to waive
compliance by the Company with certain provisions of the Senior Indenture and
certain past defaults under the Senior Indenture and their consequences. Any
such consent or waiver by the Holder of this Note shall bind such Holder and all
future Holders of this Note and of any Note issued upon the registration of
transfer hereof or in exchange hereof or in lieu hereof, whether or not notation
of such consent or waiver is made upon this Note.

         10. Obligation of Company. No reference herein to the Senior Indenture
and no provision of this Note or of the Senior Indenture shall alter or impair
the obligation of the Company, which is absolute and unconditional, to pay the
principal of and any premium, if any, and interest on this Note at the time,
place, and rate and in the coin or currency herein prescribed.

         11. Denominations, Transfer and Exchange. (a) The Notes are issuable
only in registered form without coupons in denominations of $1,000 and any
integral multiple thereof. As provided in the Senior Indenture and subject to
certain limitations therein set forth, Notes of this series are exchangeable for
a like aggregate principal amount of Notes of this series of a different
authorized denomination, as requested by the Holder surrendering the same.

         (b) As provided in the Senior Indenture and subject to certain
limitations therein set forth, the transfer of this Note is registrable in the
Security Register, upon surrender of this Note for registration of transfer at
the office or agency of the Company in any place where the principal of (and
premium, if any) and interest on this Note are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Notes of this
series, and of like tenor, of authorized denominations and for the same maturity
and aggregate principal amount, shall be issued to the designated transferee or
transferees.

         (c) No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Note for registration of transfer, the Company,
the Senior Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and neither the Company, the
Senior Trustee nor any such agent shall be affected by notice to the contrary.

         12. No Liability of Certain Persons. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under this Note or the Senior Indenture or for any
claim based on, in respect of or by reason of, such obligations or their
creation. Each Holder, by accepting a Note, waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of this Note.

         13. Governing Law. The Senior Indenture and this Note shall for all
purposes be governed by, and construed in accordance with, the internal laws of
the State of New York.

     MICHIGAN CONSOLIDATED GAS COMPANY, a corporation duly organized and
existing under the laws of the State of Michigan (the "Company", which term
includes any successor corporation under the Senior Indenture hereinafter
referred to), for value received, hereby promises to pay to Cede & Co. or
registered assigns, at the office or agency of the Company in The City of New

on June 30, 2038 (the "Stated Maturity Date"), in the coin or currency of the
United States, and to pay interest: (i) semiannually on June 30 and December 30
(x) from and including June 23, 1998 through but excluding June 30, 2003 and (y)

Tender Mode (as defined on the reverse hereof); or (ii) on such dates as
determined on the Duration/Interest Mode Determination Date (as defined on the
reverse hereof) if and so long as the Resetable MAPS are in Reset Mode (as

the Interest Payment Date next preceding the date of this Resetable MAPS to
which interest has been paid or duly provided for, unless the date hereof is a
date to which interest has been paid or duly provided for, in which case from
the date of this Resetable MAPS, or unless no interest has been paid or duly
provided for on this Resetable MAPS, in which case from June 23, 1998, until
payment of said principal sum has been made or duly provided for; provided, that
payment of interest may be made at the option of the Company by check mailed to
the address of the person entitled thereto as such address shall appear on the
Security Register of the Company as provided in the Senior Indenture.
Notwithstanding the foregoing, if the date hereof is after the 14th day of a
month in which an Interest Payment Date occurs, and before the following
Interest Payment Date, this Resetable MAPS shall bear interest from such
Interest Payment Date; provided, that if the Company shall default in the
payment of interest due on such Interest Payment Date, then this Resetable MAPS
shall bear interest from the next preceding Interest Payment Date to which
interest has been paid or duly provided for or, if no interest has been paid or
duly provided for on this Resetable MAPS, from June 23, 1998. The interest so
payable on any Interest Payment Date will, subject to certain exceptions
provided in the Senior Indenture, be paid to the person in whose name this
Resetable MAPS (or one or more Predecessor Securities) is registered at the
close of business on the fifteenth calendar day next preceding such Interest
Payment Date, whether or not such day is a Business Day (each a "Record Date").

     The rate of interest on this Resetable MAPS shall be 6.20% per annum to
June 30, 2003 (the "First Remarketing Date"). If, pursuant to the Mandatory
Tender Remarketing Agreement, dated as of the date hereof (the "Mandatory Tender
Remarketing Agreement"), between Salomon Brothers Inc, as Mandatory Tender
Remarketing Agent (the "Mandatory Tender Remarketing Agent"), and the Company,
the Mandatory Tender Remarketing Agent elects to exercise its option to remarket
the Resetable MAPS (the "Remarketing Right"), then, except as otherwise set
forth on the reverse hereof, (i) this Resetable MAPS shall be subject to
mandatory tender to the Mandatory Tender Remarketing Agent for remarketing on
the First Remarketing Date, on the terms and subject to the conditions set forth
on the reverse hereof, and (ii) from and after the First Remarketing Date and up
to but excluding June 30, 2013 (the "Second Remarketing Date"), this Resetable
MAPS shall bear interest from and including June 30, 2003 to but excluding June
30, 2013 (the "Second Remarketing Date") at the rate determined by the Mandatory
Tender Remarketing Agent in accordance with the procedures set forth in Section
2(b) on the reverse hereof (the "Interest Rate to Second Remarketing Date").

     From and after the earlier to occur of (i) the First Remarketing Date in

                                due June 30, 2038

     1. Indenture. (a) This Resetable MAPS is one of the duly authorized issue
of securities of the Company (hereinafter called the "Notes") of the series
hereinafter specified, all issued or to be issued under and pursuant to an
Indenture, dated as of June 1, 1998, as supplemented by the first supplemental
Indenture, dated as of June 18, 1998 between the Company and the Trustee (as so
supplemented, the "Senior Indenture"), duly executed and delivered by the
Company to Citibank, N.A., as Trustee (herein called the "Senior Trustee," which
term includes any successor trustee under the Senior Indenture), to which Senior
Indenture reference is hereby made for a description of the rights, limitations
of rights, obligations, duties and immunities thereunder of the Senior Trustee,
the Company and the Holders of the Notes. The Notes may be issued in one or more
series, which different series may be issued in various aggregate principal
amounts, may mature at different times, may bear interest, if any, at different
rates, may be subject to different redemption provisions (if any) and may be
subject to different sinking, purchase or analogous funds (if any) and may
otherwise vary as provided in the Indenture. This Note is one of the series
designated as the Resetable MAndatory Putable/remarketable Securities
("MAPS(sm)") due June 30, 2038 of the Company, which series is limited in 
aggregate principal amount to $75,000,000.

     (b) Interest shall be computed on the basis of a 360-day year of twelve
30-day months. The Company shall pay interest on overdue principal and, to the
extent lawful, on overdue installments of interest at the rate per annum borne
by this Note. For purposes hereof, the term "Business Day" means any day other
than a Saturday or Sunday or a day on which banking institutions in The City of
New York are required or authorized to close and, in the case of Notes in Reset
Mode that are in the Floating Rate Interest Mode that is also a London Business

dollars are transacted on the London interbank market.

     (c) Unless otherwise defined herein, all capitalized terms used herein
without definition shall have the meanings assigned to them in the Senior
Indenture.

     2. Terms of the Notes in Mandatory Tender Mode. On the date, if any, on
which the Mandatory Tender Remarketing Agent elects to exercise the Remarketing
Right in accordance with the terms hereof, the Notes shall be deemed to be in
"Mandatory Tender Mode."

     (a) Mandatory Tender on First Remarketing Date; Purchase and Settlement.
(i) Provided that the Mandatory Tender Remarketing Agent gives notice to the
Company and the Senior Trustee on a Business Day not later than eleven Business
Days prior to the First Remarketing Date of its intention to exercise the
Remarketing Right to purchase the Notes for remarketing (the "Mandatory Tender
Notification Date"), each Note shall be automatically tendered, or deemed
tendered, to the Mandatory Tender Remarketing Agent for purchase on

the Mandatory Tender Remarketing Date in accordance with Section 2(a)(ii) below,
except as set forth in Sections 6 and 7 below. The purchase price of such
tendered Notes shall be equal to 100% of the principal amount thereof. Upon such
tender, the Mandatory Tender Remarketing Agent shall have the option, in its
sole discretion, to elect to remarket the Notes in accordance with the Mandatory
Tender Remarketing Agreement for its own account at varying prices to be
determined by the Mandatory Tender Remarketing Agent at the time of each sale.
If the Mandatory Tender Remarketing Agent makes such election, the obligation of
the Mandatory Tender Remarketing Agent to purchase the Notes on the Mandatory
Tender Remarketing Date shall be subject to the conditions set forth in the
Mandatory Tender Remarketing Agreement. No Holder or actual purchaser of the
Notes ("Beneficial Owner") shall have any rights or claims under the Mandatory
Tender Remarketing Agreement or against the Company or the Mandatory Tender
Remarketing Agent as a result of the Mandatory Tender Remarketing Agent not
purchasing such Notes.

     (i) Following the Mandatory Tender Notification Date and assuming that the
Notes are remarketed by the Mandatory Remarketing Agent pursuant to the exercise
of the Remarketing Right, the tender and purchase of the Notes provided for in
Section 2(a)(i) above shall be effected as follows, subject to Sections 6 and 7
below:

          (x) All of the tendered Notes shall be automatically delivered to the
     account of the Trustee, by book-entry through DTC or any successor thereto
     pending payment of the purchase price therefor, on the Remarketing Date.

          (y) The Mandatory Tender Remarketing Agent shall make or cause the
     Trustee to make payment to DTC by book entry through DTC in accordance with
     the procedures of DTC, by 1:00 p.m., New York City time, on the Mandatory
     Tender Remarketing Date against delivery through DTC of such Beneficial
     Owner's tendered Notes, of the purchase price for tendered Notes that have
     been purchased for remarketing by the Mandatory Tender Remarketing Agent.
     The Company shall make or cause the Trustee to make payment of interest to
     DTC on the Mandatory Tender Remarketing Date by book entry through DTC by
     2:30 p.m., New York City time, on the Mandatory Tender Remarketing Date.

        (ii) In anticipation of the purchase of the Notes by the Mandatory
     Tender Remarketing Agent for remarketing or the repurchase of the Notes by
     the Company on the Remarketing Date, the Trustee shall notify the Holder
     hereof, not less than 30 days nor more than 60 days prior to the
     Remarketing Date, that all Notes will be delivered on the Mandatory Tender
     Remarketing Date through the facilities of DTC against payment of the
     purchase price therefor by the Mandatory Tender Remarketing Agent or the
     Company, as the case may be.

     (b) Determination of Interest Rate to Second Remarketing Date; Notification
Thereof. Subject to the Remarketing Dealer's election to exercise the
Remarketing Right as provided in Section 2(a)(i), by 3:30 p.m., New York City

preceding the Remarketing Date (the "Mandatory Tender Determination Date"), the
Mandatory Tender Remarketing Agent shall determine the Interest Rate to Second
Remarketing Date to the nearest one hundred-thousandth (0.00001) of one percent
per annum. The Interest Rate to Second Remarketing Date shall be equal to the
sum of 5.50% (the "Base Rate") and the Applicable Spread (as defined below),
which will be based on the Dollar Price (as defined below) of the Notes.

     The "Applicable Spread" for the Notes in Mandatory Tender Mode shall be the

basis points) above the Base Rate, obtained by the Mandatory Tender Remarketing
Agent on the Mandatory Tender Determination Date from the bids quoted by five
Reference Corporate Dealers (as defined below) for the full aggregate principal
amount of the Notes at the Dollar Price, but assuming (i) an issue date that is
the Mandatory Tender Remarketing Date, with settlement on such date without
accrued interest, (ii) a maturity date that is the Second Remarketing Date of
the Notes and (iii) a stated annual interest rate, payable semiannually on each
Interest Payment Date (as defined below), equal to the Base Rate plus the spread
bid by the applicable Reference Corporate Dealer Second Remarketing Date. If
fewer than five Reference Corporate Dealers bid as described above, then the
Applicable Spread shall be the lowest of such bid indications obtained as

Mandatory Tender Remarketing Agent, absent manifest error, shall be binding and
conclusive upon the Beneficial Owners and Holders of the Notes, the Company and
the Senior Trustee.

defined below).

     "Reference Corporate Dealers" means leading dealers of publicly traded debt
securities of the Company in The City of New York (which may include the
Mandatory Tender Remarketing Agent or one of its affiliates) selected by the
Mandatory Tender Remarketing Agent after consultation with the Company.

     "Remaining Scheduled Payments" means, with respect to the Notes, the
remaining scheduled payments of the principal thereof and interest thereon,
calculated at the Applicable Base Rate only, that would be due after the First
Remarketing Date to and including the Second Remarketing Date as determined by
the Mandatory Tender Remarketing Agent.

     "Treasury Rate" means, with respect to the First Remarketing Date, the rate
per annum equal to the semiannual equivalent yield to maturity or interpolated
(on a day count basis) yield to maturity of the Comparable Treasury Issues (as
defined below), assuming a price for the Comparable Treasury Issues (expressed
as a percentage of its principal amount), equal to the Comparable Treasury Price
(as defined below) for such Remarketing Date.

Securities selected by the Mandatory Tender Remarketing Agent as having an
actual or interpolated maturity or maturities comparable to the Second
Remarketing Date.

     "Comparable Treasury Price" means, with respect to the First Remarketing
Date, (a) the offer prices for the Comparable Treasury Issues (expressed in each
case as a percentage of its principal amount) on the Mandatory Tender
Determination Date, as set forth on "Telerate Page 500" (or such other page as
may replace Telerate Page 500) or (b) if such page (or any successor page) is
not displayed or does not contain such offer prices on such Mandatory Tender
Determination Date, (i) the average of the Reference Treasury Dealer Quotations
for the First Remarketing Date, after excluding the highest and lowest of such
Reference Treasury Dealer Quotations, or (ii) if the Mandatory Tender
Remarketing Agent obtains fewer than four such Reference Treasury Dealer

such service) or such other service displaying the offer prices specified in (a)

     "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and the First Remarketing Date, the offer prices for
the Comparable Treasury Issues (expressed in each case as a percentage of its
principal amount) quoted to the Remarketing Dealer by such Reference Treasury

     "Reference Treasury Dealer" means each of Credit Suisse First Boston
Corporation, Lehman Brothers Inc., Merrill Lynch, Pierce, Fenner & Smith
Incorporated, Morgan Stanley & Co. Incorporated and Salomon Brothers Inc (or

their affiliates shall cease to be a primary U.S. Government Notes dealer in The
City of New York (a "Primary Treasury Dealer"), the Remarketing Dealer shall
substitute therefor another Primary Treasury Dealer.

     Provided the Remarketing Right has been exercised, the Mandatory Tender
Remarketing Agent shall notify the Company, the Senior Trustee and DTC by
telephone, confirmed in writing, by 4:00 p.m., New York City time, on the
Mandatory Tender Determination Date, of the Interest Rate to Second Remarketing

pending payment of the purchase price therefor, on the First Remarketing Date,
and the Mandatory Tender Remarketing Agent shall make or cause the Senior

Owner of the Notes, by book-entry through DTC by the close of business on the
First Remarketing Date against delivery through DTC of such Beneficial Owner's
tendered Notes of 100% of the principal amount of such tendered Notes. The
transactions described above shall be executed on the First Remarketing Date
through DTC in accordance with the procedures of DTC, and

of the remarketing. In addition, the Mandatory Tender Remarketing Agent may, in
accordance with the terms of the Senior Indenture, modify the tender and
settlement procedures set forth above in order to facilitate the tender and

     3. Terms of the Notes in Reset Mode. If (i) the Mandatory Tender

First Remarketing Date (which date may also be referred to herein as the
"Mandatory Tender Remarketing Date"), on the tenth Business Day prior to the
Mandatory Tender Remarketing Date or (ii) the Second Remarketing Date, in the
event the Remarketing Right is exercised, the Notes will be deemed to be in
"Reset Mode."

     (a) Tender at Option of Beneficial Owners in Reset Mode. If the Company and
the Reset Remarketing Agent agree on the Spread on the Spread Determination Date
(as defined below) with respect to any Subsequent Spread Period, the Company and
the Reset Remarketing Agent will enter into a Reset Remarketing Agreement
Supplement (a "Reset Remarketing Agreement Supplement") under which the Reset
Remarketing Agent will agree, subject to Section 6 and 7 below and other
applicable terms and conditions set forth in such Reset Remarketing Agreement
Supplement, to purchase from tendering Holders on the Reset Tender Date all
Notes with respect to which the Reset Remarketing Agent receives a Reset Tender
Notice as described below at 100% of the principal amount thereof (the "Purchase
Price"). Except as otherwise provided in the next succeeding paragraph, each
Beneficial Owner of a Note may, at such owner's option, upon giving notice as
provided below (a "Reset Tender Notice"), tender such Note for purchase by the
Reset Remarketing Agent on the Reset Tender Date with respect to a Spread Period
at the Purchase Price. The Purchase Price shall be paid by the Reset Marketing
Agent in accordance with the standard procedures of DTC, and accounts of the
respective DTC Participants shall be debited and credited and the Notes
delivered by book-entry as necessary to effect any purchases and sales thereof.

     The Reset Tender Notice must be received by the Reset Remarketing Agent
during the period commencing at 3:00 p.m., New York City time, on the Spread
Determination Date and ending at 12:00 noon, New York City time, on the second
Business Day following such Spread Determination Date for such Subsequent Spread
Period (the "Notice Date"). Except as otherwise provided below, a Reset Tender
Notice shall be irrevocable. If a Reset Tender Notice is not received for any
reason by the Reset Remarketing Agent with respect to any Note 


                                     -9-



<PAGE>   36


by 12:00 noon, New York City time, on the Notice Date, the Beneficial Owner of 
such Note shall be deemed to have elected not to tender such Note for purchase 
by the Reset Remarketing Agent.

     (b) Determination of Duration and Interest Rate Mode. Upon each
Duration/Interest Mode Determination Date (as defined below), the mode and other
terms for the next Subsequent Spread Period shall be determined as described
below.

             (i) Floating Rate Interest Mode. If the Notes in Reset Mode are in
         Floating Rate Mode, then the following shall apply: During the Floating
         Rate Interest Mode, interest on the Notes for each Subsequent Spread
         Period shall be payable either monthly, quarterly or semiannually, as
         specified by the Company on each Duration/Interest Mode Determination
         Date. With respect to Notes in the Floating Rate Interest Mode,
         interest shall be payable, in arrears, in the case of Notes which pay:
         (a) monthly, on the thirtieth day of each month; (b) quarterly, on the
         thirtieth day of each March, June, September and December; and (c)
         semiannually, on the thirtieth day of each June and December. During
         any Subsequent Spread Period during which the Reset Mode Notes are in
         the Floating Rate Interest Mode, the interest rate on the Notes shall
         be reset either monthly, quarterly or semiannually, and the Notes shall
         bear interest at a per annum rate (computed on the basis of the actual
         number of days elapsed over a 360-day year) equal to LIBOR (as defined
         below) for the applicable Interest Period (as defined below), plus the
         applicable Spread. Interest on the Notes shall accrue from and
         including each Interest Payment Date to but excluding the next
         succeeding Interest Payment Date or maturity date, as the case may be.
         Each interest period during any Subsequent Spread Period (each, an
         "Interest Period") shall be from and including the most recent Interest
         Payment Date on which interest has been paid to but excluding the next
         Interest Payment Date. The first day of an Interest Period is referred
         to herein as an "Interest Reset Date".

             If any Interest Payment Date (other than at maturity), redemption
         date, Interest Reset Date, Duration/Interest Mode Determination Date,
         Spread Determination Date (as defined below), Commencement Date or
         Reset Tender Date would otherwise be a day that is not a Business Day,
         such Interest Payment Date, redemption date, Interest Reset Date,
         Duration/Interest Mode Determination Date, Spread Determination Date,
         Commencement Date or Reset Tender Date, as the case may be, shall be
         postponed to the next succeeding day that is a Business Day; provided,
         however, that if such next succeeding Business Day is in the next
         calendar month, such date shall occur on the immediately preceding
         Business Day.

             LIBOR applicable for an Interest Period shall be determined by the
         Rate Agent (as defined below) as of the second London Business Day (as
         defined below) preceding each Interest Reset Date (a "LIBOR
         Determination Date") in accordance with the following provisions:

                  (x) LIBOR shall be determined on the basis of the offered rate
             for deposits


                                    -10-

             in U.S. Dollars of the applicable Index Maturity commencing on
             the second London Business Day immediately following such LIBOR
             Determination Date, which appears on Telerate Page 3750 (as
             defined below) as of approximately 11:00 a.m., London time, on
             such LIBOR Determination Date. "Telerate Page 3750" means the
             display designated on page "3750" on Dow Jones Markets Limited or
             any successor thereto (or such other page as may replace the 3750
             page on that service or such other service or services as may be
             nominated by the British Bankers' Association for the purpose of
             displaying London interbank offered rates for U.S. Dollar
             deposits). If no such offered rate appears on Telerate Page 3750,
             LIBOR for such LIBOR Determination Date shall be determined in
             accordance with the provisions of paragraph (y) below. The term
             "London Business Day" means any day on which dealings in deposits
             in U.S. Dollars are transacted in the London interbank market.

                  (y) With respect to a LIBOR Determination Date on which no
             rate appears on Telerate Page 3750 as of approximately 11:00 a.m.,
             London time, on such LIBOR Determination Date, the Rate Agent shall
             request the principal London offices of each of four major
             reference banks in the London interbank market selected by the Rate
             Agent (after consultation with the Company) to provide the Rate
             Agent with a quotation of the rate at which deposits in U.S.
             Dollars of the applicable Index Maturity commencing on the second
             London Business day immediately following such LIBOR Determination
             Date, are offered by it to prime banks in the London interbank
             market as of approximately 11:00 a.m., London time, on such LIBOR
             Determination Date and in a principal amount equal to an amount of
             not less than U.S. $1,000,000 that is representative for a single
             transaction in such market at such time. If at least two such
             quotations are provided, LIBOR for such LIBOR Determination Date
             shall be the arithmetic mean of such quotations as calculated by
             the Rate Agent. If fewer than two quotations are provided, LIBOR
             for such LIBOR Determination Date shall be the arithmetic mean of
             the rates quoted as of approximately 11:00 a.m., New York City
             time, on such LIBOR Determination Date by three major banks in The
             City of New York selected by the Rate Agent (after consultation
             with the Company) for loans in U.S. Dollars to leading European
             banks, of the applicable Index Maturity commencing on the second
             London Business Day immediately following such LIBOR Determination
             Date and in a principal amount equal to an amount of not less than
             U.S. $1,000,000 that is representative for a single transaction in
             such market at such time; provided, however, that if the banks
             selected as aforesaid by the Rate Agent are not quoting as
             mentioned in this sentence, LIBOR for such LIBOR Determination Date
             shall be LIBOR determined with respect to the immediately preceding
             LIBOR Determination Date.

             The Index Maturity applicable to Notes in the Floating Rate
         Interest Mode shall be, in the case of Notes paying (x) monthly, one
         month; (y) quarterly, three months; and (z) semiannually, six months.

             The term "Rate Agent" means the entity selected by the Company as
         its agent to

         determine (i) LIBOR and the interest rate on the Notes for any
         Interest Period and/or (ii) the yield to maturity on the applicable
         United States Treasury security that is used in connection with the
         determination of the applicable Fixed Rate, and the ensuing applicable
         Fixed Rate pursuant to the Reset Remarketing Agreement.

             (ii) Fixed Rate Interest Mode. If the Notes are to be reset to the
         Fixed Rate Interest Mode, as agreed to by the Company and the Reset
         Remarketing Agent on a Duration/Interest Mode Determination, then the
         applicable Fixed Rate for the corresponding Subsequent Spread Period
         shall be determined by 1:00 p.m. on the third Business Day preceding
         the Commencement Date for such Subsequent Spread Period (the "Fixed
         Rate Determination Date"), in accordance with the following provisions:
         the Fixed Rate shall be a per annum rate and shall be determined by
         auditing the applicable Spread (as agreed to by the Company and the
         Reset Remarketing Agent on the preceding Spread Determination Date) to
         the yield to maturity (expressed as a bond equivalent, on the basis of
         a year of 365 or 366 days, as applicable, and applied on a daily basis)
         of the applicable United States Treasury security, selected by the Rate
         Agent or its agent after consultation with the Reset Remarketing Agent,
         as having a maturity comparable to the duration selected for the
         following Subsequent Spread Period, which would be used in accordance
         with customary financial practice in pricing new issues of corporate
         debt securities of comparable maturity to the duration selected for the
         following Subsequent Spread Period.

             Interest in the Fixed Rate Interest Mode shall be computed on the
         basis of a 360-day year of twelve 30-day months. Such interest shall be
         payable semiannually in arrears on the Interest Payment Dates occurring
         on each June 30 and December 30 at the applicable Fixed Rate, as
         determined by the Company and the Reset Remarketing Agent on the Fixed
         Rate Determination Date, beginning on the Commencement Date and for the
         duration of the relevant Subsequent Spread Period. Interest on the
         Notes shall accrue from and including each Interest Payment Date to but
         excluding the next succeeding Interest Payment Date or maturity date,
         as the case may be.

     If any Interest Payment Date or any redemption date in the Fixed Rate
Interest Mode falls on a day that is not a Business Day (in either case, other
than any Interest Payment Date or redemption date that falls on a Commencement
Date, in which case each such date including the Commencement Date shall be
postponed to the next day that is a Business Day), the related payment of
principal and interest shall be made on the next succeeding Business Day as if
it were made on the date such payment was due, and no interest shall accrue on
the amounts so payable for the period from and after such dates; provided,
however, that if such next succeeding Business Day is in the next calendar year,
such Interest Payment Date shall occur on the immediately preceding Business
Day.

     (c) Additional Terms of the Notes in Reset Mode. The Spread that shall be
applicable during each Subsequent Spread Period for Notes in Reset Mode shall be
the percentage (a) recommended by the Reset Remarketing Agent so as to result in
a rate that, in 



                                    -12-

<PAGE>   39


the opinion of the Reset Remarketing Agent, will enable tendered
Notes to be remarketed by the Reset Remarketing Agent at 100% of the principal
amount thereof, and (b) agreed to by the Company. The interest rate mode during
such Subsequent Spread Period shall be either the Floating Rate Interest Mode or
the Fixed Rate Interest Mode, as determined by the Company and the Reset
Remarketing Agent.

     Unless notice of redemption of the Notes as a whole has been given, the
duration, redemption dates, redemption type, redemption prices (if applicable),
Commencement Date, Interest Payment Dates and interest rate mode (and any other
relevant terms) for each Subsequent Spread Period shall be established by 3:00
p.m., New York City time, on the tenth Business Day prior to the Commencement
Date of each Subsequent Spread Period (each a "Duration/Interest Mode
Determination Date"). In addition, the Spread for each Subsequent Spread Period
shall be established by 1:00 p.m., New York City time, on the fifth Business Day
prior to the Commencement Date of such Subsequent Spread Period (each, a "Spread
Determination Date"). Thirty calender days prior to the First Remarketing Date,
the Company shall request that DTC provide preliminary notification to its
Participants that, on the date that is ten Business Days prior to the First
Remarketing Date either (i) the Remarketing Right will have been exercised and
the Notes will be subject to Mandatory tender on the First Remarketing Date or
(ii) the Notes will be in Reset Mode and a Duration/Interest Mode Determination
Date will occur on such date. If the Mandatory Tender Remarketing Agent does not
provide notification of its intention to exercise the Remarketing Right on the
Mandatory Tender Notification Date, on or before the date that is ten Business
Days prior to the First Remarketing Date, the Company shall request that DTC
notify its Participants of the occurrence of a Duration/Interest Mode
Determination Date and of the procedures that must be followed if any Beneficial
Owner of a Note wishes to tender such Note. With respect to all Subsequent
Spread Periods established after the First Remarketing Date, the Company shall
request not later than five nor more than ten calendar days prior to any
Duration/Interest Mode Determination Date, that DTC notify its Participants of
such Duration/Interest Mode Determination Date and of the procedures that must
be followed if any Beneficial Owner of a Notes wishes to tender such Note. In
the event that DTC or its nominee is no longer the Holder of record of the
Notes, the Company shall notify the Holders of such information within such
period of time.

     In the event that the Company and the Reset Remarketing Agent do not agree
on the Spread for any Subsequent Spread Period, then the Company shall be
required unconditionally to repurchase and retire all of the Notes on the Reset
Tender Date at a price equal to 100% of the principal amount thereof, together
with accrued interest to the Reset Tender Date. In the event that the Reset
Remarketing Agent fails to purchase any Notes tendered on the Reset Tender Date,
then the Company shall be required unconditionally to repurchase and retire any
Notes tendered and not purchased by the Reset Remarketing Agent.

     All percentages resulting from any calculation of any interest rate for the
Notes shall be rounded, if necessary, to the nearest one hundred thousandth of a
percentage point, with five one millionths of a percentage point rounded upward,
and all dollar amounts shall be rounded 


                                    -13-

<PAGE>   40


to the nearest cent, with one-half cent being rounded upward.

     4. Security; Release Date. Prior to the Release Date (as hereinafter
defined), the Notes shall be secured by First Mortgage Bonds designated as
Collateral Bonds, Series B (the "Collateral Bonds"), delivered by the Company to
the Senior Trustee for the benefit of the Holders of the Notes. Prior to the
Release Date, the Company shall make payments of the principal of, and premium,
if any, and or interest on, the Collateral Bonds to the Senior Trustee, which
payments shall be applied by the Senior Trustee to satisfaction of all
obligations then due on the Notes. Reference is made to the Mortgage Indenture
and the Senior Indenture for a description of the rights of the Senior Trustee
as holder of the Collateral Bonds, the property mortgaged and pledged under the
Mortgage Indenture and the rights of the Company and of the Mortgage Trustee in
respect thereof, the duties and immunities of the Mortgage Trustee and the terms
and conditions upon which the Collateral Bonds are secured and the circumstances
under which additional First Mortgage Bonds may be issued.

     FROM AND AFTER SUCH TIME AS ALL FIRST MORTGAGE BONDS (OTHER THAN COLLATERAL
BONDS) ISSUED UNDER THE MORTGAGE INDENTURE HAVE BEEN RETIRED THROUGH PAYMENT,
REDEMPTION OR OTHERWISE AT, BEFORE OR AFTER THE MATURITY THEREOF (THE "RELEASE
DATE"), THE COLLATERAL BONDS SHALL CEASE TO SECURE THE NOTES IN ANY MANNER
PROVIDED THAT NO DEFAULT OR EVENT OF DEFAULT HAS OCCURRED AND AT SUCH TIME IS
CONTINUING UNDER THE SENIOR INDENTURE. IN CERTAIN CIRCUMSTANCES PRIOR TO THE
RELEASE DATE AS PROVIDED IN THE SENIOR INDENTURE, THE COMPANY IS PERMITTED TO
REDUCE THE AGGREGATE PRINCIPAL AMOUNT OF A SERIES OF COLLATERAL BONDS HELD BY
THE TRUSTEE, BUT IN NO EVENT PRIOR TO THE RELEASE DATE TO AN AMOUNT LESS THAN
THE AGGREGATE OUTSTANDING PRINCIPAL AMOUNT OF THE SERIES OF NOTES INITIALLY
ISSUED CONTEMPORANEOUSLY WITH SUCH COLLATERAL BONDS.

     5. Maintenance of Book-Entry System. (a) The tender and settlement
procedures set forth in Section 2 above, including provisions for payment by
purchasers of Notes in the remarketing or for payment to selling Beneficial
Owners of tendered Notes, shall be subject to modification, notwithstanding any
provision to the contrary set forth in Article 9 of the Senior Indenture, to the
extent required by DTC or, if the book-entry system is no longer available for
the Notes at the time of the remarketing, to the extent required to facilitate
the tendering and remarketing of Notes in certificated form. In addition, either
of the Remarketing Agents may, notwithstanding any provision to the contrary set
forth in Article 9 of the Senior Indenture, modify the settlement procedures set
forth herein in order to facilitate the settlement process.

     (b) The Company hereby agrees with the Senior Trustee and the holders of
Notes that at all times, notwithstanding any provision to the contrary set forth
in the Senior Indenture, (i) it shall use its best efforts to maintain the Notes
in book-entry form with DTC or any successor thereto and to appoint a successor
thereto to the extent necessary to maintain the Notes in book-entry form and
(ii) it shall waive any discretionary right that it otherwise may have under


                                    -14-

<PAGE>   41

the Senior Indenture to cause the Notes to be issued in certificated form.

     6. Repurchase. If the Notes are in Mandatory Tender Mode, in the event that
(i) the Mandatory Remarketing Agent for any reason does not notify the Company
of the Interest Rate to Second Remarketing Date by 4:00 p.m., New York City
time, on the Mandatory Tender Determination Date, or (ii) prior to the First
Remarketing Date, the Mandatory Tender Remarketing Agent has resigned and no
successor has been appointed on or before the Mandatory Tender Determination
Date, or (iii) since the Mandatory Tender Notification Date, the Mandatory
Tender Remarketing Agent terminates the Mandatory Tender Remarketing Agreement
because of the occurrence of a material adverse change in the condition of the
Company and its subsidiaries, considered as one enterprise, or because an Event
of Default, or any event which, with the giving of notice or passage of time, or
both, would constitute an Event of Default, with respect to the Notes has
occurred and is continuing, or any other event constituting a termination event
under the Mandatory Tender Remarketing Agreement has occurred, or (iv) the
Mandatory Tender Remarketing Agent for any reason does not purchase all tendered
Notes on the First Remarketing Date, the Company shall repurchase such Notes on
the First Remarketing Date at a price equal to 100% of the principal amount of
such Notes plus all accrued and unpaid interest, if any, to the First
Remarketing Date.

     If the Notes are in Reset Mode, in the event that (i) the Company and the
Reset Remarketing Agent fail for any reason to agree on a Spread for a
Subsequent Spread Period, or (ii) prior to any Commencement Date, the Reset
Remarketing Agent has resigned and no successor thereto has been appointed on or
before the Duration/Interest Mode Determination Date, or (iii) since the Spread
Determination Date, the Reset Remarketing Agent terminates the Reset Remarketing
Agreement because of the occurrence of a material adverse change in the
condition of the Company and its subsidiaries, considered as one enterprise, or
because an Event of Default, or any event which, with the giving of notice or
passage of time, or both, would constitute an Event of Default, with respect to
the Notes has occurred and is continuing, or any other event constituting a
termination event under the Reset Remarketing Agreement has occurred, or (iv)
the Reset Remarketing Agent for any reason does not purchase any Notes tendered
on the Reset Tender Date, the Company shall repurchase any such Notes tendered
but not purchased by the Reset Remarketing Agent on the First Remarketing Date
at a price equal to 100% of the principal amount of such Notes plus all accrued
and unpaid interest, if any, to the applicable Reset Tender Date.

     7. Redemption. (a) Notwithstanding any election by the Mandatory Tender
Remarketing Agent to remarket the Notes on the Mandatory Tender Remarketing
Date, the tendering of the Notes for purchase by the Mandatory Tender
Remarketing Agent on such date as set forth in Section 2(b)(ii) above shall be
subject to the right of the Company to redeem the Notes from the Mandatory
Tender Remarketing Agent as provided in Section 7(b) below.

     (b) The Company, in its sole and absolute discretion, shall have the
right, upon notice to the Mandatory Tender Remarketing Agent and the Senior
Trustee not later than the close of business on the Business Day immediately
preceding the Mandatory Tender Determination 



                                    -15-

<PAGE>   42

Date, to irrevocably elect to redeem the Notes, in whole but not in part,
from the Mandatory Tender Remarketing Agent on the Mandatory Tender Remarketing
Date at the Optional Redemption Price. The "Optional Redemption Price" shall be
the greater of (i) 100% of the principal amount of the Notes and (ii) the sum of
the present values of the Remaining Scheduled Payments thereon, as determined by
the Mandatory Tender Remarketing Agent, discounted to the Mandatory Tender
Remarketing Date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate, plus in either case accrued and
unpaid interest from the Mandatory Tender Remarketing Date on the principal
amount being redeemed to the date of redemption. If the Company elects to redeem
the Notes, it shall pay the redemption price therefor in same-day funds by wire
transfer to an account designated by the Mandatory Tender Remarketing Agent on
the Mandatory Tender Remarketing Date.

     (c) If the Notes are in Reset Mode, on each Commencement Date and on those
Interest Payment Dates specified as redemption dates by the Company on the
Duration/Interest Mode Determination Date in connection with any Subsequent
Spread Period, the Notes may be redeemed, at the option of the Company, in whole
or in part, upon notice thereof given at any time during the 30-calendar-day
period ending on the tenth Business Day prior to the redemption date (provided
that notice of any partial redemption must be given at least 15 calendar days
prior to the redemption date), in accordance with the redemption type selected
on the Duration/Interest Mode Determination date. In the event that less than
all of the outstanding Notes are to be so redeemed, the Notes to be redeemed
shall be selected by such method as the Senior Trustee shall deem fair and
appropriate.

     The redemption type to be chosen by the Company and the Reset Remarketing
Agent on the Duration/Interest Mode Determination Date may be one of the
following as defined herein: (i) Par Redemption; (ii) Premium Redemption; or
(iii) Make-Whole Redemption. "Par Redemption" means redemption at a redemption
price equal to 100% of the principal amount thereof, plus accrued interest
thereon, if any, to the redemption date. "Premium Redemption" means redemption
at a redemption price or prices greater than 100% of the principal amount
thereof, plus accrued interest thereon, if any, to the redemption date, as
determined on the Duration/Interest Mode Determination date. "Make-Whole
Redemption" means redemption at a redemption price equal to the Make-Whole
Amount (as defined below), if any, with respect to such Notes. Unless otherwise
specified by the Company on any Duration/Interest Mode Determination Date, the
redemption type will be a Par Redemption.

     "Make-Whole Amount" means, in connection with any optional redemption or
accelerated payment of any Note, any amount equal to the greater of (i) 100% of
the principal amount and (ii) the sum of the present values of the remaining
scheduled payments of principal and interest thereon from the redemption date to
the end of the applicable Subsequent Spread Period, computed by discounting such
payments, in each case, to the date of redemption on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the applicable
Treasury Rate plus the Reinvestment Spread, plus accrued interest on the
principal amount thereof to the date of redemption.



                                    -16-

<PAGE>   43

     "Reinvestment Spread" means, with respect to the Notes, a number, expressed
as a number of basis points or as a percentage, selected by the Company and
agreed to by the Reset Remarketing Agent on the Duration/Interest Mode
Determination Date.

     8. Effect of Event of Default. In case an Event of Default with respect to
the Notes shall occur and be continuing, the unpaid principal of the Notes may
be declared due and payable, in the manner, with the effect and subject to the
conditions provided in the Senior Indenture.

     9. Amendments and Waivers. The Senior Indenture may be modified by the
Company and the Senior Trustee without consent of any Holder with respect to
certain matters as described in the Indenture. In addition, the Senior Indenture
permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of
the Holders of the Notes of each series to be affected under the Senior
Indenture at any time by the Company and the Senior Trustee with the consent of
the Holders of a majority in principal amount of the Notes at the time
Outstanding of each series to be affected. The Senior Indenture also contains
provisions permitting the Holders of a majority in principal amount of the Notes
of each series at the time Outstanding, on behalf of the Holders of all Notes of
such series, to waive compliance by the Company with certain provisions of the
Senior Indenture and certain past defaults under the Senior Indenture and their
consequences. Any such consent or waiver by the Holder of this Note shall bind
such Holder and all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether
or not notation of such consent or waiver is made upon this Note.

     10. Obligation of Company. No reference herein to the Senior Indenture and
no provision of this Note or of the Senior Indenture shall alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the
principal of and any premium, if any, and interest on this Note at the time,
place, and rate and in the coin or currency herein prescribed.

     11. Denominations, Transfer and Exchange. (a) The Notes are issuable only
in registered form without coupons in denominations of $1,000 and any integral
multiple thereof. As provided in the Senior Indenture and subject to certain
limitations therein set forth, Notes of this series are exchangeable for a like
aggregate principal amount of Notes of this series of a different authorized
denomination, as requested by the Holder surrendering the same.

     (b) As provided in the Senior Indenture and subject to certain limitations
therein set forth, the transfer of this Note is registrable in the Security
Register, upon surrender of this Note for registration of transfer at the office
or agency of the Company in any place where the principal of (and premium, if
any) and interest on this Note are payable, duly endorsed by, or accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by the Holder hereof or his attorney duly
authorized in 


                                    -17-

writing, and thereupon one or more new Notes of this series, and of like
tenor, of authorized denominations and for the same maturity and aggregate
principal amount, shall be issued to the designated transferee or transferees.

     (c) No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith. Prior to
due presentment of this Note for registration of transfer, the Company, the
Senior Trustee and any agent of the Company or the Trustee may treat the Person
in whose name this Note is registered as the owner hereof for all purposes,
whether or not this Note be overdue, and neither the Company, the Senior Trustee
nor any such agent shall be affected by notice to the contrary.

     12. No Liability of Certain Persons. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under this Note or the Senior Indenture or for any
claim based on, in respect of or by reason of, such obligations or their
creation. Each Holder, by accepting a Note, waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of this Note.

     13. Governing Law. The Senior Indenture and this Note shall for all
purposes be governed by, and construed in accordance with, the internal laws of
the State of New York.

on the Maturity Date specified above, at the corporate trust office of the

Trust Company (now known as Citibank, N.A., successor trustee, as "Mortgage
Trustee") and Ralph E. Morton (Robert T. Kirchner, successor individual trustee
and, together with Citibank, N.A., the "Secured Trustees") as restated in Part
II of the Twenty-ninth Supplemental Indenture dated as of July 15, 1989, which
became effective on April 1, 1994, to which indenture and all indentures
supplemental thereto executed on and after July 15, 1989 reference is hereby
made for a description of the property mortgaged and pledged, the nature and
extent of the security, the terms and conditions upon which the bonds are, and
are to be, issued and secured, and the rights of the holders of the bonds and of
the Secured Trustees in respect of such security (which indenture and all
indentures supplemental thereto, including the Thirty-fifth Supplemental
Indenture dated as of June 18, 1998, are hereinafter collectively called the
"Secured Indenture"). As provided in the Secured Indenture, the bonds may be for
various principal sums and are issuable in series, which may mature at different
times, may bear interest at different rates and may otherwise vary as therein
provided. The bonds represented by this certificate are part of a Series
designated "Collateral Bonds," herein called Collateral Bonds, created by the

         With the consent of the Company and to the extent permitted by and as
provided in the Secured Indenture and the Senior Indenture, the rights and
obligations of the Company and/or the rights of the holders of the Collateral
Bonds of the Thirty-second Series and/or the terms and provisions of the Secured
Indenture may be modified or altered by such affirmative vote or votes of the
holders of the Related Notes then outstanding as are specified in the Senior
Indenture.

         The Collateral Bonds shall be redeemed if and to the extent Related
Notes are redeemed, as provided in the Senior Indenture with respect to the
Related Notes and in the Related Notes.

         In case an event of default as defined in the Secured Indenture or the
Senior Indenture shall occur, the principal of the Collateral Bonds may become
or be declared due and payable in the manner, with the effect, and subject to
the conditions provided in the Secured Indenture and the Senior Indenture.

         The Senior Trustee has agreed pursuant to the Senior Indenture to hold
the Collateral Bonds as collateral for the benefit of the holders of the Related
Notes under all circumstances and not to transfer (except to a successor
trustee) such Collateral Bonds until the earlier of the Release Date or the
prior retirement of the Related Notes through redemption, repurchase or
otherwise. "Release Date" means the date on which all First Mortgage Bonds of
the Company issued and outstanding under the Secured Indenture, other than the
Collateral Bonds, have been retired (at, before or after the maturity thereof)
through payment, redemption or otherwise provided that no default or event of
default has occurred and is continuing under the Senior Indenture. On the
Release Date, the Senior Trustee shall deliver to the Company for cancellation
all Collateral Bonds, and the Company shall cause the Senior Trustee to provide
notice to all holders of Related Notes of the occurrence of the Release Date. As
a result, on the Release Date, the Collateral Bonds shall cease to secure the
Related Notes. Following the Release Date, the Company shall cause the Secured
Indenture to be closed, and the Company shall not issue any additional
Collateral Bonds to be issued thereunder. From and after the Release Date, the
Company's obligations in respect of the Collateral Bonds shall be satisfied and
discharged.

         No recourse shall be had for the payment of the principal of, or the
interest on, the Collateral Bonds, or for any claim based hereon or otherwise in
respect of the Collateral Bonds or the Secured Indenture, Senior Indenture or
any indenture supplemental to either thereof, or against any incorporator,
stockholder, director or officer, past, present or future, of the Company, as
such, or any predecessor or successor corporation, either directly or through
the Company or any such predecessor or successor corporation, whether by virtue
of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability, whether at common law,
in equity, by any constitution, statute or otherwise, of incorporators,
stockholders, directors or officers being waived and released by the owner
hereof and every owner of any Related Note by the acceptance of the Collateral
Bonds or such Related Note, as the case may be, and as part of the consideration
for the issue thereof, and being likewise waived and released pursuant to the
Secured Indenture and the Senior Indenture.

         The Collateral Bonds shall not be valid or become obligatory for any
purpose unless and until the certificate of authentication hereon shall have
been manually executed by the Mortgage Trustee or its successor in trust under
the Secured Indenture.

         IN WITNESS WHEREOF, MICHIGAN CONSOLIDATED GAS COMPANY has caused this
certificate to be executed under its name with the signature of its Chairman,

         WHEREAS, the Company desires in and by this Thirty-fifth Supplemental
Indenture to create a Thirty-second series of bonds and certain subseries
thereunder to be issued under the Indenture, to designate or otherwise
distinguish such series, to specify the particulars necessary to describe and
define the same, and to specify such other provisions and agreements in respect
thereof as are in the Indenture provided or permitted; and

         WHEREAS, all the conditions and requirements necessary to make this
Thirty-fifth Supplemental Indenture, when duly executed and delivered, a valid,
binding and legal instrument in accordance with its terms and for the purposes
herein expressed, have been done, performed and fulfilled, and the execution and
delivery of this Thirty-fifth Supplemental Indenture in the form and with the
terms hereof have been in all respects duly authorized;



                                        2

<PAGE>   5


         NOW, THEREFORE, it is agreed by and between the Company and the
Trustees as follows:

                                    ARTICLE I
          CREATION OF AN ISSUE OF FIRST MORTGAGE BONDS, DESIGNATED AND
                       DISTINGUISHED AS "COLLATERAL BONDS"

         SECTION 1. There is hereby created a series of bonds to be issued under
and secured by the Indenture, to be known as "First Mortgage Bonds," designated
and distinguished as "Collateral Bonds" of the Company (herein collectively
sometimes called the "Collateral Bonds"). The Collateral Bonds may be issued
without limitation as to aggregate principal amount except as provided in the
Indenture and in this Thirty-fifth Supplemental Indenture. The Collateral Bonds
shall be registered bonds without coupons and shall be dated as of the date of
the authentication thereof by the Trustee.

         Separate series of Collateral Bonds are being issued by the Company
contemporaneously with the issuance of separate series of senior debt securities
of the Company including, initially, those designated "Extendable Mandatory Par
Put Remarketed Securities ("MOPPRS(sm)") due June 30, 2038" and "Resetable
Mandatory Putable/remarketable Securities ("MAPS(sm)"), due June 30, 2038" and
are being issued and delivered to Citibank, N.A., as trustee (in such capacity,
together with any successor trustee(s), the "Senior Trustee") under the
Indenture dated as of June 1, 1998, governing such senior debt securities (the
"Senior Indenture"), in such capacity, as collateral for the benefit of the
holders of such securities. The series of such senior debt securities
collateralized by any Collateral Bonds shall be referred to as the "Related
Notes" with respect to such Collateral Bonds.

         The Collateral Bonds shall bear interest at such rate or rates and be
payable on such date or dates, shall mature and be subject to mandatory or
optional redemption on such date or dates and shall have such other terms and
provisions not inconsistent with the Indenture as are set forth in the forms of
Collateral Bonds attached as Appendix I and II hereto (herein sometimes called
the "Bond Forms") or otherwise as the Board of Directors may determine in
accordance with a resolution filed with the Mortgage Trustee and referring to
this Thirty-fifth Supplemental Indenture (herein called an "Authorizing
Resolution"). Resolutions of the Board of Directors of the Company establishing
the terms of the Related Notes with respect to any Collateral Bonds shall
constitute Authorizing Resolutions for purposes of establishing the terms of
such Collateral Bonds. An Authorizing Resolution may alter, correct or change
the form of any of the Bond Forms prior to the issue and authentication of any
Collateral Bond provided that the substantive terms contained in any of any of
the Bond Forms is not changed in any manner adverse to the holder of any
Collateral Bonds.

         So long as there is no existing default in the payment of interest on
the Collateral Bonds, all Collateral Bonds authenticated by the Trustee after
the Record Date specified for any interest payment date, and prior to such
interest payment date (unless the issue date hereinafter specified is after such
Record Date) shall be dated the date of authentication, but shall bear interest
from such interest payment date, and the person in whose name any Collateral
Bond is registered at the close of business on any Record Date with respect to
any interest payment date shall be entitled to receive the interest payable on
such interest payment date notwithstanding any transfer or exchange of such
Collateral Bond subsequent to the Record Date and on or prior to such interest
payment date, except if and to the extent the Company shall default in the
payment of the interest due on such interest payment date, in which case such
defaulted interest shall be paid to the person in whose name such Collateral
Bond is registered on the Record Date for the interest payment date fixed by the
Company for the payment of such  defaulted  interest,  provided  that in no case
shall such Record  Date be less than ten days after  notice  thereof  shall have
been mailed to all  registered  holders of Collateral  Bonds;  and provided that
interest  payable on a maturity  date shall be payable to the person to whom the
principal thereof is payable.  If the issue date of any Collateral Bond is after
such Record Date,  such Bond shall bear interest from the issue date but payment
of interest shall commence on the second  interest  payment date next succeeding
the  issue  date.  Any  notice  which is  mailed  as  herein  provided  shall be
conclusively  presumed to have been properly and sufficiently  given on the date
of such mailing, whether or not the holder receives notice.


                                        3

<PAGE>   6




         The terms "Record Date"and "Business Day" as used herein are defined in
the Bond Forms.

         The term "issue date" as used herein with respect to Collateral Bonds
of a designated interest rate and maturity shall mean the date of first
authentication of Collateral Bonds of such designated interest rate and
maturity.

         As used in this Section 1, the term "default in the payment of
interest" means failure to pay interest on the applicable interest payment date
disregarding any period of grace permitted by Section 9.01 of the Indenture.

         The Company shall make payments of the principal of, and premium or
interest on, the Collateral Bonds to the Senior Trustee, which payments shall be
applied by the Senior Trustee to satisfaction of obligations on the Related
Notes in respect of such Collateral Bonds.

         SECTION 2. Each series of Collateral Bonds shall be redeemed if and to
the extent the Related Notes with respect to such Collateral Bonds are redeemed,
as provided in the Senior Indenture and in such Related Notes. The redemption
price in respect of any Collateral Bonds (including principal, premium, if any,
and interest thereon) shall be the redemption price applicable to the Related
Notes with respect to such Collateral Bonds. Any notice required to be furnished
to the holders of the Collateral Bonds or the Trustees relating to the
redemption of such Collateral Bonds shall be considered furnished by the
delivery of appropriate notice to the holders of the Related Notes or the Senior
Trustee, as the case may be, as provided in the Senior Indenture and the Related
Notes with respect to such Collateral Bonds. Any redemption payment made by the
Company on the Related Notes (whether for principal, premium, if any, or
interest) shall be applied by the Senior Trustee as payment of the redemption
price in respect of the correspondingly redeemed Collateral Bonds. In the event
the Related Notes with respect to a series of Collateral Bonds are redeemed in
part, an equivalent aggregate principal amount of the corresponding series of
Collateral Bonds shall be so redeemed, the Senior Trustee, as holder of the
Collateral Bonds as collateral for such Related Notes, shall deliver to the
Mortgage Trustee for cancellation an equivalent principal amount of Collateral
Bonds of the series corresponding to the Related Notes so redeemed, and the
Company shall execute and the Mortgage Trustee shall authenticate and deliver,
without charge, to the Senior Trustee, as holder thereof, one or more new
Collateral Bonds of authorized denominations for the unredeemed balance of any
Collateral Bonds surrendered for redemption in connection with the redemption of
the Related Notes.

         SECTION 3. The Collateral Bonds shall be registered bonds without
coupons. The Mortgage Trustee shall be the registrar and paying agent for the
Collateral Bonds, which duties it hereby accepts. Collateral Bonds may be issued
in the denomination of $1,000 or any integral multiple thereof.

         SECTION 4. Collateral Bonds shall be exchangeable, at the option of the
registered owners thereof and upon surrender thereof at the corporate trust
office of the Trustee in the Borough of Manhattan, The City of New York, New
York, for registered bonds of the same aggregate principal amount and other
terms, but of different authorized denomination or denominations, such exchanges
to be made without service charge (except for any stamp tax or other
governmental charge).

         Every bond so surrendered shall be accompanied by a proper transfer
power duly executed by the registered owner or by duly authorized attorney
transferring such bond to the Company, and the signature to such transfer power
shall be guaranteed to the satisfaction of the Trustee. All bonds so surrendered
shall be forthwith canceled and delivered to or upon the order of the Company.
All bonds executed, authenticated and delivered in exchange for bonds so
surrendered shall be valid obligations of the Company, evidencing the same debt
as the bonds surrendered, and shall be secured by the same lien and be entitled
to the same benefits and protection as the bonds in exchange for which they are
executed, authenticated and delivered.

         The Company shall not be required to make any such exchange or any
registration of transfer (1) during a period of fifteen days next preceding any
interest payment date, but only if there is an existing default in the payment
of interest on the Collateral Bonds on which such payment is due or (2) after
the bond so presented for


                                        4

<PAGE>   7

exchange or registration of transfer,  or any portion  thereof,  has been called
for redemption and notice thereof given to the registered owner.

         SECTION 5. Pending the preparation of definitive Collateral Bonds the
Company may from time to time execute, and upon its written order, the Trustee
shall authenticate and deliver, in lieu of such definitive bonds and subject to
the same provisions, limitations and conditions, one or more temporary bonds, in
registered form, of any denomination specified in the written order of the
Company for the authentication and delivery thereof, and with such omissions,
insertions and variations as may be determined by the Board of Directors of the
Company. Such temporary bonds shall be substantially of the tenor of the bonds
to be issued as herein before recited, but such temporary bonds may, in lieu of
the statement of the specific redemption prices required to be set forth in
Collateral Bonds in definitive form.

         If any such temporary Collateral Bonds shall at any time be so
authenticated and delivered in lieu of definitive bonds, the Company shall upon
request at its own expense prepare, execute and deliver to the Trustee and
thereupon, upon the presentation and surrender of temporary bonds, the Trustee
shall authenticate and deliver in exchange therefor, without charge to the
holder, definitive bonds of the same series and other terms, if any, and for the
same principal sum in the aggregate as the temporary bonds surrendered. All
temporary bonds so surrendered shall be forthwith canceled by the Trustee and
delivered to or upon the order of the Company. Until exchanged for definitive
bonds the temporary bonds shall in all respects be entitled to the lien and
security of the Indenture and all supplemental indentures.


                                   ARTICLE II
                            ISSUE OF COLLATERAL BONDS

         Collateral Bonds, of the Thirty-second Series, in the aggregate
principal amount of $400,000,000 including, without limitation, Collateral Bonds
designated Collateral Bonds, Series A, in the aggregate principal amount of
$75,000,000 and Collateral Bonds, Series B, in the aggregate principal amount of
$75,000,000, may be executed, authenticated and delivered from time to time as
permitted by the provisions of the Indenture.


                                   ARTICLE III
                                  THE TRUSTEES

         The Trustees shall not be responsible in any manner whatsoever for or
in respect of the validity or sufficiency of this Thirty-fifth Supplemental
Indenture or the due execution hereof by the Company, or for or in respect of

statements are made solely by the Company.

         Except as herein otherwise provided, no duties, responsibilities or
liabilities are assumed, or shall be construed to be assumed, by the Trustees by
reason of this Thirty-fifth Supplemental Indenture other than as set forth in
the Indenture and this Thirty-fifth Supplemental Indenture is executed and
accepted on behalf of the Trustees, subject to all the terms and conditions set

                                   ARTICLE IV
                            MISCELLANEOUS PROVISIONS

on the Maturity Date specified above, at the corporate trust office of the
Mortgage Trustee hereinafter named in the Borough of Manhattan, The City of New
York, New York, or at the principal office of any successor in trust, in lawful
money of the United States of America, and to pay interest thereon at the

Date succeeding such date. If the Company shall default in the payment of
interest due on any Interest Payment Date, then interest shall be payable from

on the relevant Record Date with respect to an Interest Payment Date shall be
entitled to receive the interest payable on such Interest Payment Date, except
that if the Company shall default in the payment of interest due on such

on the Record Date for the Interest Payment Date fixed by the Company for the
payment of such defaulted interest, provided that in no case shall such Record
Date be less than ten days after notice thereof shall have been mailed to all
registered holders of Collateral Bonds. The term "Record Date" as used herein
with respect to any Interest Payment Date shall mean the last Business Day which
is more than ten calendar days prior to such Interest Payment Date.

         "Business Day" means any day other than a Saturday or Sunday or a day
on which banking institutions in the city of New York are required or authorized
to close and, in the case of Related Notes in the Floating Rate Mode (as defined
in the form of Related Note), a day that is also a London Business Day. "London
Business Day" means any day on which dealings in deposits in U.S. dollars are
transacted in the London interbank market.

         The bonds represented by this certificate, of the series hereinafter
specified, are bonds of the Company (herein called the "bonds") known as its
"First Mortgage Bonds," issued and to be issued in one or more series under, and
all equally and ratably secured by, an Indenture of Mortgage and Deed of Trust
dated as of March 1, 1944, duly executed by the Company to City Bank Farmers
Trust Company (now known as Citibank, N.A., successor trustee, as "Mortgage
Trustee") and Ralph E. Morton (Robert T. Kirchner, successor individual trustee
and, together with Citibank, N.A., the "Secured Trustees") as restated in Part
II of the Twenty-ninth Supplemental Indenture dated as of July 15, 1989, which
became effective on April 1, 1994, to which indenture and all indentures
supplemental thereto executed on and after July 15, 1989 reference is hereby
made for a description of the property mortgaged and pledged, the nature and
extent of the security, the terms and conditions upon which the bonds are, and
are to be, issued and secured, and the rights of the holders of the bonds and of
the Secured Trustees in respect of such security (which indenture and all
indentures supplemental thereto, including the Thirty-fifth Supplemental
Indenture dated as of June 18, 1998, are hereinafter collectively called the
"Secured Indenture"). As provided in the Secured Indenture, the bonds may be for
various principal sums and are issuable in series, which may mature at different
times, may bear interest at different rates and may otherwise vary as therein
provided. The bonds represented by this certificate are part of a Series
designated "Collateral Bonds," herein called Collateral Bonds, created by the
Thirty-fifth Supplemental Indenture dated as of June 18, 1998, as provided for
in the Secured Indenture.

         With the consent of the Company and to the extent permitted by and as
provided in the Secured Indenture and the Senior Indenture, the rights and
obligations of the Company and/or the rights of the holders of the Collateral
Bonds of the Thirty-second Series and/or the terms and provisions of the Secured
Indenture may be modified or altered by such affirmative vote or votes of the
holders of the Related Notes then outstanding as are specified in the Senior
Indenture.

         The Collateral Bonds shall be redeemed if and to the extent Related
Notes are redeemed, as provided in the Senior Indenture with respect to the
Related Notes and in the Related Notes.

         In case an event of default as defined in the Secured Indenture or the
Senior Indenture shall occur, the principal of the Collateral Bonds may become
or be declared due and payable in the manner, with the effect, and subject to
the conditions provided in the Secured Indenture and the Senior Indenture.

         The Senior Trustee has agreed pursuant to the Senior Indenture to hold
the Collateral Bonds as collateral for the benefit of the holders of the Related
Notes under all circumstances and not to transfer (except to a successor
trustee) such Collateral Bonds until the earlier of the Release Date or the
prior retirement of the Related Notes through redemption, repurchase or
otherwise. "Release Date" means the date on which all First Mortgage Bonds of
the Company issued and outstanding under the Secured Indenture, other than the
Collateral Bonds, have been retired (at, before or after the maturity thereof)
through payment, redemption or otherwise provided that no default or event of
default has occurred and is continuing under the Senior Indenture. On the
Release Date, the Senior Trustee shall deliver to the Company for cancellation
all Collateral Bonds, and the Company shall cause the Senior Trustee to provide
notice to all holders of Related Notes of the occurrence of the Release Date. As
a result, on the Release Date, the Collateral Bonds shall cease to secure the
Related Notes. Following the Release Date, the Company shall cause the Secured
Indenture to be closed, and the Company shall not issue any additional
Collateral Bonds to be issued thereunder. From and after the Release Date, the
Company's obligations in respect of the Collateral Bonds shall be satisfied and
discharged.

         No recourse shall be had for the payment of the principal of, or the
interest on, the Collateral Bonds, or for any claim based hereon or otherwise in
respect of the Collateral Bonds or the Secured Indenture, Senior Indenture or
any indenture supplemental to either thereof, or against any incorporator,
stockholder, director or officer, past, present or future, of the Company, as
such, or any predecessor or successor corporation, either directly or through
the Company or any such predecessor or successor corporation, whether by virtue
of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability, whether at common law,
in equity, by any constitution, statute or otherwise, of incorporators,
stockholders, directors or officers being waived and released by the owner
hereof and every owner of any Related Note by the acceptance of the Collateral
Bonds or such Related Note, as the case may be, and as part of the consideration
for the issue thereof, and being likewise waived and released pursuant to the
Secured Indenture and the Senior Indenture.

         The Collateral Bonds shall not be valid or become obligatory for any
purpose unless and until the certificate of authentication hereon shall have
been manually executed by the Mortgage Trustee or its successor in trust under
the Secured Indenture.

         IN WITNESS WHEREOF, MICHIGAN CONSOLIDATED GAS COMPANY has caused this
certificate to be executed under its name with the signature of its Chairman,
Chief Executive Officer, President, Vice Chairman or a Vice-President, or any
other officer selected by the Board of Directors, under its corporate seal,

will enable the Reset Remarketing Agent to remarket, for delivery on any Reset
Tender Date (as defined below), all tendered Senior Notes with respect to which
the Reset Remarketing Agent receives a Reset Tender Notice (as defined below) at

the Tender Date at a price equal to 100% of the principal amount thereof,
together with accrued interest to the Reset Tender Date. In the event that the
Reset Remarketing Agent fails to purchase any Notes tendered on the Tender Date,

days, as applicable, and applied on a daily basis) of the applicable United

         British Bankers' Association for the purpose of displaying London
         interbank offered rates for U.S. Dollar deposits). If no such offered

         that is representative for a single transaction in such market at such
         time. If at least two such quotations are provided, LIBOR for such
         LIBOR Determination Date will be the arithmetic mean of such quotations

         such LIBOR Determination Date will be LIBOR determined with respect to
         the immediately preceding LIBOR Determination Date.

                  The Index Maturity applicable to Notes in the Floating Rate
Interest Mode will be, in the case of Notes paying (i) monthly, one month; (ii)

registration statement under the 1933 Act and a then current prospectus relating
to the Senior Notes (and Collateral Bonds, if applicable) to be used by the

to such revised prospectus from and after the time it is first provided to the
Reset Remarketing Agent for such use); and

                           (ii) The Company shall also furnish to the Reset

         The Company agrees, at its expense, to provide the Reset Remarketing
Agent with as many copies of the foregoing written materials and other Company

use in connection with the remarketing of Senior Notes and consents to the use
thereof for such purpose.

                  (c) If, at any time during which the Reset Remarketing Agent
would be obligated to take any action under this Agreement, any event or
condition known to the Company relating to or affecting the Company, any
subsidiary thereof or the Senior Notes shall occur which could reasonably be

referred to in paragraph (b) above or any document incorporated therein by
reference (collectively, the "Reset Remarketing Materials") to contain an untrue

join as a Holder or Beneficial Owner, as the case may be, in any action which
any Holder or Beneficial Owner of Senior Notes may be entitled to exercise or
take pursuant to the Indenture with like effect as if it did not act in any
capacity hereunder. Salomon Brothers Inc, in its individual capacity, either as
principal or agent, may also engage in or have an interest in any financial or

capacity hereunder.

"Representation Date") as follows:

                  (a) It has made all the filings with the Commission that it is
required to make under the Securities Exchange Act of 1934, as amended (the
"1934 Act"), and the rules and regulations thereunder (the "1934 Act
Regulations") (collectively, the "1934 Act Documents"), (ii) each 1934 Act
Document complies in all material respects with the requirements of the 1934 Act
and 1934 Act Regulations, and each 1934 Act Document did not at the time of
filing with the Commission, and as of each Representation Date, as modified or
superseded by any subsequently filed 1934 Act Document on or prior to such
Representation Date, will not, include an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading and (iii) the applicable Reset Remarketing
Materials (as defined herein), as of each Representation Date after the date
hereof, as modified or superseded by any subsequently filed 1934 Act Document on
or prior to such Representation Date (or, if applicable, by any document filed
pursuant to the 1933 Act and the rules and regulations thereunder (the "1933 Act
Regulations")), will not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

                  (b) The Company further represents and warrants to the Reset
Remarketing Agent as of each Representation Date as follows:

                           (i) The accountants who certified the financial
         statements and supporting schedules included or incorporated by
         reference in the 1934 Act Documents are independent public accountants

         specified; such financial statements have been prepared in conformity

         change and no development which could reasonably be expected to result
         in a material adverse change in the condition, financial or otherwise,

         Company and its subsidiaries considered as one enterprise, whether or

         Effect"), (B) there have been no transactions entered into by the
         Company or any of its subsidiaries, other than those in the ordinary
         course of business, which are material with respect to the Company and
         its subsidiaries considered as one enterprise, and (C) except for

         and operate its properties and to conduct its business as presently
         conducted and as described in the 1934 Act Documents and to enter into
         and perform its obligations under this Agreement; and the Company is
         duly qualified as a foreign corporation to transact business and is in
         good standing in each other jurisdiction in which such qualification is
         required, whether by reason of the ownership or leasing of property or
         the conduct of business, except where the failure so to qualify or to
         be in good standing would not result in a Material Adverse Effect.

                           (v) The shares of issued and outstanding capital
         stock of the Company have been duly authorized and validly issued and

         failure so to qualify or to be in good standing would not result in a
         Material Adverse Effect; except as otherwise disclosed in the 1934 Act
         Documents, all of the issued and outstanding capital stock of each such
         subsidiary has been duly authorized and validly issued, is fully paid

                           (viii) The Indenture has been duly authorized,
         executed and delivered by the Company and duly qualified under the
         Trust Indenture Act of 1939, as amended (the "1939 Act"), and, assuming
         it has been duly executed and delivered by the Trustee, constitutes a
         valid and binding agreement of the Company, enforceable against the
         Company in accordance with its terms, except as the enforcement thereof
         may be limited by bankruptcy, insolvency (including, without
         limitation, all laws relating to fraudulent transfers, reorganization,
         moratorium or similar laws affecting enforcement of creditors' rights
         generally and except as enforcement thereof is subject to general
         principles of equity (regardless of whether enforcement is considered
         in a proceeding in equity or at law) (the "Bankruptcy Exceptions").

                           (ix) The issuance and delivery by the Company of the
         Collateral Bonds to the Trustee constitute a sale by the Company of the

         interest in the Collateral Bonds for the benefit of the holders of the
         Senior Notes.

                           (x) The Secured Indenture constitutes a legally valid
         and direct enforceable first mortgage lien, except as the same may be
         limited by the laws of the State of Michigan (where all of the property
         covered thereby is located) affecting the remedies for the enforcement
         of the security provided for therein, which laws do not make inadequate
         the remedies necessary for the realization of the benefits of such
         security, or as the same may be limited by the Bankruptcy Exceptions,
         upon substantially all of the Company's properties and franchises, now
         owned or hereafter acquired, free from all prior liens, charges or
         encumbrances, except as set forth in subparagraph (xviii) below, and
         except, in the case of property hereafter acquired, any thereof
         existing at the time of acquisition.

                           (xi) The Senior Notes have been duly authorized and
         executed by the Company and authenticated, issued and delivered in the
         manner provided for in the Indenture, and constitute valid and binding

         accordance with their terms, except as the enforcement thereof may be
         limited by bankruptcy, insolvency (including, without limitation, all

         in equity or at law), and are in the form contemplated by, and entitled
         to the benefits of, the Indenture.

                           (xii) The Collateral Bonds have been duly authorized
         and executed by the Company and authenticated, issued, and delivered in
         the manner provided for in the Secured Indenture and have been issued
         and delivered to the Trustee as provided for in the Thirty-Fifth
         Supplemental Indenture as security for the Senior Notes, and constitute
         legal, valid and binding obligations of the Company, enforceable
         against the Company in accordance with their terms except to the extent
         that enforcement thereof may be limited by the Bankruptcy Exceptions.
         The Collateral Bonds are in the form contemplated by, and entitled to
         the benefits of, the Secured Indenture.

         subsidiaries is in violation of its charter or by-laws or in default in
         the performance or observance of any material obligation, agreement,
         covenant or condition contained in any contract, indenture, mortgage,
         deed of trust, loan or credit agreement, note, lease or other agreement
         or instrument to which the Company or any of its respective
         subsidiaries is a party or by which it or any of them may be bound, or
         to which any of the property or assets of the Company or any subsidiary
         is subject (collectively, "Agreements and Instruments") or in violation
         of any applicable law, rule or regulation or any judgment, order, writ
         or decree of any government, governmental instrumentality or court,
         domestic or foreign, having jurisdiction over the Company or any of its
         subsidiaries or any of their respective properties or assets, which
         violation or default would singly or in the aggregate, have a Material
         Adverse Effect.

                           (xiv) The execution, delivery and performance of the
         Purchase Agreement, this Agreement, the Mandatory Tender Remarketing
         Agreement, the Indenture, the Senior Notes, the Thirty-Fifth
         Supplemental Indenture, the Collateral Bonds and any other agreement or
         instrument entered into or issued or to be entered into or issued by
         the Company in connection with the transactions contemplated hereby or

         hereunder and under the Indenture, the Secured Indenture, the
         Thirty-Fifth Supplemental Indenture, the Senior Notes, and the
         Collateral Bonds have been duly authorized by all necessary corporate
         action and do not and will not, whether with or without the giving of
         notice or passage of time or both, conflict with or constitute a breach
         of, or default or Repayment Event (as defined below) under, or result
         in the creation or imposition of any lien, charge or encumbrance upon
         any property or assets of the Company or any subsidiary pursuant to
         (other than the lien of the Indenture on the Collateral Bonds), the
         Agreements and Instruments (except for such conflicts, breaches or
         defaults or liens, charges or encumbrances that would not result in a
         Material Adverse Effect), nor will such action result in any violation
         of the provisions of the charter or by-laws of the Company or any
         subsidiary or any applicable law, statute, rule, regulation, judgment,
         order, writ or decree of any government, government instrumentality or
         court, domestic or foreign, having jurisdiction over the Company or any
         subsidiary or any of their assets, properties or operations. As used
         herein, a "Repayment Event" means any event or condition which gives
         the holder of any note, debenture or other evidence of indebtedness (or
         any person acting on such holder's behalf) the right to require the
         repurchase, redemption or repayment of all or a portion of such
         indebtedness by the Company or any subsidiary.

         investigation before or brought by any court or governmental agency or
         body, domestic or foreign, now pending, or, to the knowledge of the
         Company, threatened, against or affecting the Company or any
         subsidiary, which is required to be disclosed in the 1934 Act Documents
         (other than as disclosed therein), or which might reasonably be
         expected to result in a Material Adverse Effect, or which might
         reasonably be expected to materially and adversely affect the
         properties or assets thereof or the consummation of the transactions
         contemplated in this Agreement or the performance by the Company of its
         obligations hereunder; the aggregate of all pending legal or
         governmental proceedings to which the Company or any subsidiary is a
         party or of which any of their respective property or assets is the
         subject which are not

         litigation incidental to the business, could not reasonably be expected
         to result in a Material Adverse Effect.

                           (xvi) No filing with, or authorization, approval,
         consent, license, order, registration, qualification or decree of, any
         court or governmental authority or agency is necessary or required for

         connection with the remarketing of the Senior Notes hereunder or the
         consummation of the transactions contemplated by this Agreement or for
         the due execution, delivery or performance of the Indenture by the
         Company, except such as have or shall have been already obtained.

                           (xvii) No labor dispute with the employees of the
         Company or any of its subsidiaries exists or, to the knowledge of the
         Company, is imminent, and neither the Company is aware of any existing
         or imminent labor disturbance by the employees of any of its or any of
         its subsidiary's principal suppliers, manufacturers, customers or
         contractors which, in either case, may reasonably be expected to result
         in a Material Adverse Effect.

                           (xviii) There are no contracts or documents which are
         required to be described in the Registration Statement, the Prospectus
         or the documents incorporated by reference therein or to be filed as
         exhibits thereto which have not been so described and/or filed as
         required.

                           (xix) The Company has good and marketable title to
         the properties specifically described in and conveyed by the Secured
         Indenture (except such property as may have been disposed of or
         released from the lien thereof in accordance with the terms thereof)
         subject only to the lien of the Secured Indenture, to permissible
         encumbrances as defined in the Secured Indenture, as to property
         acquired by the Company subsequent to the execution of the Original
         Secured Indenture, to any liens existing thereon or purchase money
         liens placed thereon at the time of such acquisition as permitted by
         the Secured Indenture, and to certain other reservations, rights of
         grantors under revocable permits, easements, licenses, zoning laws and
         ordinances and restrictions and minor defects or irregularities of

         thereby in the operation of the business of the Company; the Company
         and its subsidiaries have good and marketable title to all personal
         property owned by them, in each case free and clear of all liens,
         encumbrances and defects except the liens of the Secured Indenture and
         such liens, encumbrances and defects as do not materially affect the
         value of such property and do not interfere with the use made and
         proposed to be made of such property by the Company and its
         subsidiaries; and any real property and buildings held under lease by
         the Company and its subsidiaries are held by them under valid,
         subsisting and enforceable leases with such exceptions as are not
         material and do not interfere with the use made and proposed to be made
         of such property and buildings by the Company and its subsidiaries; the
         pipeline, distribution main and underground gas storage easements
         enjoyed by the Company and its subsidiaries are valid, subsisting and

         now operated by each of them; the Company and its subsidiaries are in
         compliance with the terms and conditions of all such Governmental
         Licenses, except where the failure to so comply would not, singly or in
         the aggregate, have a Material Adverse Effect; all of the Governmental
         Licenses are valid and 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 and the Prospectus, there are no legal or governmental

         Materials and except as would not, singly or in the aggregate, result

         surface or subsurface strata) or wildlife, including, without
         limitation, laws and regulations relating to the release or threatened
         release of chemicals, pollutants, contaminants, wastes, toxic
         substances, hazardous substances, petroleum or petroleum products
         (collectively, "Hazardous Materials") or to the manufacture,

         subsidiaries.

         such terms are defined in the Public Utility Holding Company Act of

         presently exempt from the provisions of the 1935 Act (except Section 9
         thereof).

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

         result in, or that has constituted or that reasonably might be expected
         to constitute, the stabilization or manipulation of the price of any

         Rule 175 under the 1933 Act) contained in the Registration Statement,

                           (xxvi) The Company is not an "investment company" or
         an entity "controlled" by an "investment company" as such terms are
         defined in the Investment Company Act of 1940, as amended.

                           (xxvii) The Senior Notes are rated "A2" by Moody's
         Investors Service, Inc. and "A" by Standard & Poor's Rating Services, a

each case including the documents incorporated by reference therein, if such are
required pursuant to such Section 5(b).

                  Section 8. Conditions to the Reset Remarketing Agent's
Obligations. The obligations of the Reset Remarketing Agent under this Agreement
have been undertaken in reliance on, and shall be subject to,

                  (a) the due performance by the Company of its obligations and
agreements as set forth in this Agreement and the accuracy of the
representations and warranties in this Agreement and any certificate delivered
pursuant hereto, and

                  (b) the further condition that none of the following events
shall have occurred at any time:

                           (i) the rating of any securities of the Company shall

                           (ii) without the prior written consent of the Reset
         Remarketing Agent, neither the Indenture (including the Senior Notes)
         nor the Secured Indenture (including the Collateral Bonds) shall have
         been amended in any manner, or otherwise contain any provision not
         contained therein as of the date hereof, that in either case in the
         judgment of

         the Reset Remarketing Agent materially and adversely changes the nature
         of the Senior Notes or the Collateral Bonds, as the case may be, or the
         remarketing procedures (it being understood that, notwithstanding the
         provisions of this clause (ii), the Company shall not be prohibited
         from amending the Indenture);

                           (iii) trading in any securities of the Company or any
         of its affiliates shall have been suspended or materially limited by
         the Commission or the New York Stock Exchange, or if trading generally
         on the American Stock Exchange or the New York Stock Exchange or in the
         Nasdaq National Market shall have been suspended or materially limited,
         or minimum or maximum prices for trading shall have been fixed, or
         maximum ranges for prices shall have been required, by any of said
         exchanges or by such system or by order of the Commission, the National
         Association of Securities Agents, Inc. or any other governmental
         authority, or if a banking moratorium shall have been declared by
         either Federal or New York authorities;

                           (iv) there shall have occurred any material adverse
         change in the financial markets in the United States or the
         international financial markets, any outbreak of hostilities or
         escalation thereof or other calamity or crisis or any change or
         development involving a prospective change in national or international
         political, financial or economic conditions, in each case the effect of
         which is such as to make it, in the judgment of the Reset Remarketing
         Agent, impracticable to remarket the Senior Notes or to enforce
         contracts for the sale of the Senior Notes;

                           (v) an Event of Default (as defined in the
         Indenture), or any event which, with the giving of notice or passage of
         time, or both, would constitute an Event of Default, with respect to

         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, shall have occurred;

                           (vii) the Senior Notes are not maintained in
         book-entry form with DTC or any successor thereto; provided, that the
         Reset Remarketing Agent, in its sole discretion and subject to receipt
         of an opinion of counsel for the Company reasonably satisfactory to the
         Reset Remarketing Agent, may waive the foregoing condition if in the
         Reset Remarketing Agent's judgment the Indenture and the Senior Notes
         can be amended, and they are amended, so as to permit the remarketing
         of the Senior Notes in certificated form and otherwise as contemplated
         herein;

                  (c) The obligations of the Reset Remarketing Agent to purchase
and remarket the Senior Notes shall also be subject to the terms and conditions
of the applicable Reset Remarketing Agreement Supplement.

                  Section 9. Indemnification. (a) The Company agrees to
indemnify and hold harmless the Reset Remarketing Agent and its officers,

if any, who controls the Reset Remarketing Agent within the meaning of Section
20 of the 1934 Act as follows:

                           (i) against any loss, liability, claim, damage or
         expense whatsoever (collectively, "Damages"), as incurred, arising out
         of, (A) the failure to have an effective Registration Statement under
         the 1933 Act relating to the Senior Notes, if required, or the failure
         to satisfy the prospectus delivery requirements of the 1933 Act because
         the Company failed to provide the Reset Remarketing Agent with a
         Prospectus for delivery, as required by Section 5 hereof, or (B) any
         untrue statement or alleged untrue statement of a material fact
         contained in any of the Reset Remarketing Materials (including any
         incorporated documents), or (C) the omission or alleged omission
         therefrom of a material fact necessary to make the statements therein,
         in the light of the circumstances in which they were made, not
         misleading, or (D) any violation by the Company of, or any failure by
         the Company to perform any of its obligations under, this Agreement, or
         (E) the acts or omissions of the Reset Remarketing Agent in connection
         with its duties and obligations to determine the Interest Rate or other
         terms with respect to any Subsequent Spread Period, as provided
         hereunder, except Damages that are finally judicially determined to be
         due to its gross negligence or willful misconduct;

                           (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 investigation
         or proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever arising out of, or based upon,
         any of items (A) through (E) in clause (i) above; provided that
         (subject to clause (d) below) such settlement is effected with the
         written consent of the Company, which consent shall not be unreasonably
         withheld; and

                           (iii) against any and all expense whatsoever, as
         incurred (including the fees and disbursements of counsel chosen by the
         Reset Remarketing Agent), 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 arising out of, or based upon, any of items (A)
         through (E) in clause (i) above to the extent that any such expense is
         not paid under (i) or (ii) above;

provided, however, that the foregoing indemnity shall not apply to any losses,
liabilities, claims, damages and expenses to the extent arising out of any
untrue statement or omission made in reliance upon and in conformity with
written information furnished to the Company by the Reset Remarketing Agent
expressly for use in the Reset Remarketing Materials.

                  (b) 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 clause (a) above, counsel to the indemnified
parties shall be selected by Salomon Brothers Inc, and, in the case







                                      -16-



<PAGE>   17



of parties indemnified pursuant to clause (b) above, counsel to the indemnified
parties shall be selected by the Company. An indemnifying party may participate
at its own expense in the defense of any such action; provided, however, that
counsel to the indemnifying party shall not (except with the consent of the
indemnified party) also be counsel to the indemnified party. In no event shall
the indemnifying parties be liable for fees and expenses of more than one
counsel (in addition to any local counsel) separate from their own counsel for
all indemnified parties in connection with any one action or separate but
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances. No indemnifying party shall, without the
prior written consent of the indemnified parties, settle or compromise or
consent to the entry of any judgment with respect to any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever in respect of which indemnification or
contribution could be sought under this Section 9 or Section 10 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 or fault, culpability or a failure to act by or on behalf of any
indemnified party.

                  (c) 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 clause 9 (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.

                  (d) The indemnity agreements contained in this Section 10
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the Reset Remarketing Agent, and shall
survive the termination or cancellation of this Agreement and the remarketing of
any Senior Notes hereunder.

                  Section 10. Contribution. If the indemnification provided for
in Section 9 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of any losses, liabilities, claims,
damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Reset Remarketing Agent on the other hand from
the remarketing of the Senior Notes pursuant to this Agreement or (ii) if the
allocation provided by clause (i) is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company on the one
hand and of the Reset Remarketing Agent on the other hand in connection with the
acts, failures to act, statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

                  The relative benefits received by the Company on the one hand
and the Reset Remarketing Agent on the other hand in connection with the
remarketing of the Senior Notes


                                      -17-



<PAGE>   18



pursuant to this Agreement shall be deemed to be in the same respective
proportions as (i) the aggregate principal amount of the Senior Notes, and (ii)
the aggregate positive difference, if any, between the price at which the Senior
Notes are sold by the Reset Remarketing Agent in the remarketing and the price
paid by the Reset Remarketing Agent for the Senior Notes tendered on any Reset
Tender Date.

                  The relative fault of the Company on the one hand and the
Reset Remarketing Agent on the other hand shall be determined by reference to,
among other things, the responsibility hereunder of the applicable party for any
act or failure to act relating to the losses, liabilities, claims, damages or
expenses incurred or, in the case of any losses, liabilities, claims, damages or
expenses arising out of any untrue or alleged untrue statement of a material
fact contained in any of the Reset Remarketing Materials or the omission or
alleged omission to state a material fact therefrom, whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Company or by the
Reset Remarketing Agent and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

                  The Company and the Reset Remarketing Agent agree that it
would not be just and equitable if contribution pursuant to this Section 10 were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to above in this
Section 10. The aggregate amount of losses, liabilities, claims, damages and
expenses incurred by an indemnified party and referred to above in this Section
10 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 act
or failure to act or untrue or alleged untrue statement or omission or alleged
omission.

                  Notwithstanding the provisions of this Section 10, the Reset
Remarketing Agent shall not be required to contribute any amount in excess of
the amount by which the total price at which the Senior Notes remarketed by it
and resold to the public were sold to the public exceeds the amount of any
damages which the Reset Remarketing Agent has otherwise been required to pay by
reason of any act or failure to act for which it is responsible hereunder or any
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 10, each person, if any, who
controls the Reset Remarketing Agent 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 Reset Remarketing Agent, and each officer and director of
the Company who signed the Registration Statement, and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act shall have the same rights to contribution as the Company.

Subject to Section 3 hereof relating to the payment of fees and expenses, this
Agreement shall terminate as to the Reset Remarketing Agent on the effective
date of the removal of such Reset Remarketing Agent pursuant to Section 4
hereof.

                  Section 12. Reset Remarketing Agent's Performance: Duty of
Care. The duties and obligations of the Reset Remarketing Agent hereunder shall
be determined solely by the express provisions of this Agreement, the
Senior Notes and the Indenture, the Secured Indenture and the Collateral Bonds
and the applicable Reset Remarketing Agreement Supplement. No implied covenants
or obligations of or against the Reset Remarketing Agent shall be read into
this Agreement, the Indenture or the Secured Indenture. In the absence of bad
faith on the part of the Reset Remarketing Agent, the Reset Remarketing Agent
may conclusively rely upon any document furnished to it, which purports to
conform to the requirements of this Agreement, the Indenture, or the Secured
Indenture, as to the truth of the statements expressed in any of such
documents. The Reset Remarketing Agent shall be protected in acting upon any
document or communication reasonably believed by it to have been signed,
presented or made by the proper party or parties. The Reset Remarketing Agent
shall incur no liability hereunder to any Beneficial Owner or Holder of Senior
Notes in its individual capacity or as Reset Remarketing Agent for any action
or failure to act in connection with the remarketing or otherwise. The Reset
Remarketing Agent shall incur no liability to the Company with respect to
calculation of the Interest Rate applicable to any Interest Period, except as a
result of gross negligence or willful misconduct on its part.

                  Section 13.       GOVERNING LAW.  THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE

SUCH STATE.

accordance with the provisions hereof, this Agreement shall remain in full force
and effect from the date hereof until the first day thereafter on which no
Senior Notes are outstanding.

                  Section 15. Successors and Assigns. The rights and obligations
of the Company hereunder may not be assigned or delegated to any other person
without the prior written consent of Salomon Brothers Inc, the rights and
obligations of Salomon Brothers Inc hereunder may not be assigned or delegated
to any other person without the prior written consent of the Company, and any
attempt by either party to do so will be unenforceable. This Agreement shall
inure to the benefit of and be binding upon the Company and Salomon Brothers Inc
and their respective permitted successors and assigns. The terms "successors"
and "assigns" shall not include any purchaser of any Senior Notes merely because
of such purchase.

                  Section 16. Headings. Section headings have been inserted in
this Agreement as a matter of convenience of reference only, and it is agreed
that such section headings are not a part of this Agreement and will not be used
in the interpretation of any provisions of this Agreement.

                  Section 17. Severability. If any provision of this Agreement
shall be held or deemed to be or shall, in fact, be invalid, inoperative or
unenforceable as applied in any particular case in any or all jurisdictions
because it conflicts with any provision of any constitution, statute, rule 






                                      -19-

effect of rendering the provision in question invalid, inoperative or
unenforceable in any other case, circumstances or jurisdiction, or of rendering

unenforceable to any extent whatsoever.

hereto shall be made in writing or transmitted by any standard form of

                     RESET REMARKETING AGREEMENT SUPPLEMENT

                  Salomon Brothers Inc, (the "Reset Remarketing Agent") hereby
agrees to purchase the Senior Notes described below (the "Senior Notes") that
have been tendered by the holders thereof for sale on _____________, _____ (the
"Reset Tender Date").

                  It is acknowledged and agreed that the Senior Notes need not
be further registered under the Securities Act of 1933, as amended (the "Act"),
and that, in connection with the remarketing of the Senior Notes by the Reset
Remarketing Agent in accordance with the terms of the Reset Remarketing
Agreement dated as of June 23, 1998, no prospectus meeting the requirements of
Section 10 of the Act need be delivered, or filed pursuant to Rule 424 under the
Act.

                  It is understood that the Reset Remarketing Agent will deliver
to purchasers and prospective purchasers, in connection with the remarketing,
one or more forms of written communication describing the terms of the Senior
Notes (each, a "Reset Remarketing Memorandum"), the form of each of which shall
be delivered to Michigan Consolidated Gas Company, a Michigan corporation (the
"Company"), not less than two Business Days prior to its use and subject to the
approval of the Company prior to its use by the Reset Remarketing Agent, which
approval shall not be unreasonably withheld or delayed.

                  The Reset Remarketing Agent shall offer to purchase Senior
Notes and purchase validly tendered Senior Notes on the Reset Tender Date in
accordance with all applicable laws and regulations and interpretations of the
Securities and Exchange Commission.

                  The representations and warranties made pursuant to the
above-referenced Reset Remarketing Agreement (other than paragraphs (b)(viii),
(x), (xi) and (xii) of Section 7); Section 3(o) of the attached Purchase
Agreement (which date shall be the date of the Reset Remarketing Agreement
Supplement and the relevant Reset Tender Date); Section 8 of the attached
Purchase Agreement (except that Section 8 is amended to allow termination of
this Agreement by the Agent if the Company's representations and warranties
therein are not accurate and correct); paragraphs (c) and (f) of Section 5 of
the attached Purchase Agreement; and Section 7 and the last paragraph of Section
5 of the attached Purchase Agreement are incorporated in their entirety into
this Agreement and made applicable to the obligations of the Reset Remarketing
Agent to the extent applicable to any remarketing of the Senior Notes, except as
explicitly amended hereby. The terms "Registration Statement" and "Prospectus"
shall be deemed to refer to each such document as amended to the date hereof and
the Tender Date, and the term "Incorporated Documents" shall similarly be deemed
to include those filed and incorporated by reference through such dates.

                  If the Reset Remarketing Agent determines, based on advice of
counsel, that changes in applicable law, regulations or interpretations of the
Securities and Exchange Commission make it necessary or advisable to deliver a
current prospectus in connection with this Remarketing, the attached Purchase
Agreement shall apply in its entirety. All references in such Purchase Agreement
to (i) the "Agent" shall be deemed to refer to the Reset Remarketing Agent, (ii)
the "Securities" shall be deemed to refer to the Senior Notes, (iii) the
Purchase Agreement shall be deemed to refer to the





<PAGE>   23



Reset Remarketing Agreement Supplement, and (iv) "Closing Date" shall be deemed
to refer to the Reset Tender Date. To the extent the provisions of such Purchase
Agreement refer to the "Prospectus" or the "Registration Statement," such
references shall be deemed to refer to any Remarketing Memorandum or
registration statement, if any, that the Company is required to prepare or file
pursuant to applicable law, regulations or interpretations of the Securities and
Exchange Commission in effect at the time of such remarketing of the Senior
Notes, including all documents incorporated by reference therein. For the
purposes of Section 6 of the attached Purchase Agreement, the relative benefit
received by the Company on the one hand and the Reset Remarketing Agent on the
other in connection with the remarketing of the Senior Notes pursuant to this
Agreement shall be deemed to be in the same respective proportions as the
aggregate public offering price of the Senior Notes bears to the remarketing fee
received by the Reset Remarketing Agent pursuant to this Agreement.

                  All capitalized terms not otherwise defined in this Agreement
have the respective meanings assigned thereto in the Senior Notes, the form of
which is attached hereto.

         British Bankers' Association for the purpose of displaying London
         interbank offered rates for U.S. Dollar deposits). If no such offered
         rate appears on Telerate Page 3750, LIBOR for such LIBOR Determination

         for a single transaction in such market at such time; provided,
         however, that if the banks selected as aforesaid by the Rate Agent are
         not quoting as mentioned in this sentence, LIBOR for such LIBOR
         Determination Date will be LIBOR determined with respect to the
         immediately preceding LIBOR Determination Date.

                  The Index Maturity applicable to Notes in the Floating Rate
Interest Mode will be, in the case of Notes paying (i) monthly, one month; (ii)

                  (b) (i) The Company shall furnish to the Reset Remarketing
         Agent, if the Reset Remarketing Agent determines, based on advice of
         counsel, that changes in applicable law, regulations or interpretations
         of the Securities and Exchange Commission make it necessary or
         advisable to deliver a current prospectus in connection with a
         Remarketing, a then currently effective registration statement under
         the 1933 Act and a then current prospectus relating to the Senior Notes
         (and Collateral Bonds, if applicable) to be used by the Reset
         Remarketing Agent for remarketing and resale of the Senior Notes (such
         registration statement (whether consisting of the registration
         statement relating to the initial issuance of the Senior Notes and
         Collateral Bonds, or any amendment thereto or a new registration
         statement) and any amendments thereto, including any such prospectus
         (whether consisting of the prospectus relating to the initial issuance
         of the Senior Notes and Collateral Bonds or any amendment or supplement
         thereto or a new prospectus) relating to the Senior Notes (and
         Collateral Bonds, if applicable) constituting a part thereof, and all
         documents incorporated therein by reference, as from time to time
         amended or supplemented pursuant to the 1934 Act, the 1933 Act, or
         otherwise, are referred to herein as the "Registration Statement" and
         the "Prospectus," respectively, except that if any revised prospectus
         shall be provided to the Reset Remarketing Agent by the Company for use
         in connection with the remarketing of the Senior Notes which differs
         from the Prospectus on file at the Commission at the time the
         Registration Statement becomes effective, the term "Prospectus" shall
         refer to such revised prospectus from and after the time it is first
         provided to the Reset Remarketing Agent for such use); and

                           (ii) The Company shall also furnish to the Reset
         Remarketing Agent in connection with the remarketing of Senior Notes
         such other information as the Reset Remarketing Agent may reasonably

Remarketing Agent may reasonably request for use in connection with the
remarketing of Senior Notes and consents to the use thereof for such purpose.

                  (c) If, at any time during which the Reset Remarketing Agent
would be obligated to take any action under this Agreement, any event or
condition known to the Company relating to or affecting the Company, any
subsidiary thereof or the Senior Notes shall occur which could reasonably be
expected to cause any of the reports, documents, materials or information
referred to in paragraph (b) above or any document incorporated therein by
reference (collectively, the "Reset Remarketing Materials") to contain an untrue
statement of a material fact or omit to state a material fact, the Company shall
promptly notify the Reset Remarketing Agent in writing of the circumstances and
details of such event or condition.

                  (d) So long as the Senior Notes are outstanding, the Company
will file all documents required to be filed with the Commission pursuant to the
1934 Act within the time periods required by the 1934 Act and the 1934 Act
Regulations.

                  (e) Except as otherwise provided herein, the Company agrees
that neither it nor any of its subsidiaries or affiliates shall defease,
purchase or otherwise acquire, or enter into any agreement to defease, purchase
or otherwise acquire, any of the Senior Notes prior to the remarketing thereof
by the Reset Remarketing Agent.

                  (f) Notwithstanding any provision to the contrary set forth in
the Indenture, the Company shall (i) use its best efforts to maintain the Senior

buy, sell, hold and deal in any of the Senior Notes. Merrill Lynch, as Holder or
Beneficial Owner of the Senior Notes may exercise any vote or join as a Holder
or Beneficial Owner, as the case may be, in any action which any Holder or
Beneficial Owner of Senior Notes may be entitled to exercise or take pursuant to
the Indenture with like effect as if it did not act in any capacity hereunder.
Merrill Lynch, in its individual capacity, either as principal or agent, may
also engage in or have an interest in any financial or other transaction with
the Company as freely as if it did not act in any capacity hereunder.

                  (b) The Company may purchase Senior Notes in the remarketing,
provided that the Interest Rate established with respect to the Senior Notes in
any such Remarketing is not different from the Interest Rate that would have

                  (a) It has made all the filings with the Commission that it is
required to make under the Securities Exchange Act of 1934, as amended (the
"1934 Act"), and the rules and regulations thereunder (the "1934 Act
Regulations") (collectively, the "1934 Act Documents"), (ii) each 1934 Act
Document complies in all material respects with the requirements of the 1934 Act
and 1934 Act Regulations, and each 1934 Act Document did not at the time of
filing with the Commission, and as of each Representation Date, as modified or
superseded by any subsequently filed 1934 Act Document on or prior to such
Representation Date, will not, include an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading and (iii) the applicable Reset Remarketing
Materials (as defined herein), as of each Representation Date after the date
hereof, as modified or superseded by any subsequently filed 1934 Act Document on
or prior to such Representation Date (or, if applicable, by any document filed
pursuant to the 1933 Act and the rules and regulations thereunder (the "1933 Act
Regulations")), will not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

                  (b) The Company further represents and warrants to the Reset
Remarketing Agent as of each Representation Date as follows:

                           (i) The accountants who certified the financial
         statements and supporting schedules included or incorporated by
         reference in the 1934 Act Documents are independent public accountants
         as required by the 1933 Act and the 1933 Act Regulations.

                           (ii) The financial statements included or
         incorporated by reference in the 1934 Act Documents, together with the
         related schedules and notes, present fairly the financial position of
         the Company and its consolidated subsidiaries at the dates indicated
         and the statement of operations, stockholders' equity and cash flows of
         the Company and its consolidated subsidiaries 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 1934
         Act Documents present fairly in accordance with GAAP the information
         required to be stated therein. The pro forma financial statements and
         the related notes thereto, if any, included or incorporated by
         reference in the 1934 Act Documents present fairly the information
         shown therein, have been prepared in accordance with the Commission's
         rules and guidelines with respect to pro forma financial statements and

         adjustments used therein are appropriate to give effect to the
         transactions and circumstances referred to therein.

                           (iii) Since the respective dates as of which
         information is given in the 1934 Act Documents, 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, whether or not arising in
         the ordinary course of business (a "Material Adverse

         Company or any of its subsidiaries, other than those in the ordinary
         course of business, which are material with respect to the Company and
         its subsidiaries considered as one enterprise, and (C) except for
         regular quarterly dividends on the Company's common stock in amounts
         per share that are consistent with past practice, there has been no
         dividend or distribution of any kind declared, paid or made by the

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

                           (v) The shares of issued and outstanding capital
         stock of the Company have been duly authorized and validly issued and
         are fully paid and non-assessable; none of the outstanding shares of

         or by-laws of the Company, under any agreement to which the Company or
         any of its subsidiaries is a party or otherwise.

                           (vi) Each subsidiary of the Company has been duly

         such qualification is required, whether by reason of the ownership or
         leasing of property or the conduct of business, except where the
         failure so to qualify or to be in good standing would not result in a
         Material Adverse Effect; except as otherwise disclosed in the 1934 Act
         Documents, all of the issued and outstanding capital stock of each such
         subsidiary has been duly authorized and validly issued, is fully paid
         and non-assessable and is owned by the Company, as the case may be,
         directly or through subsidiaries, free and clear of any security
         interest, mortgage, pledge, lien, encumbrance, claim or equity; none of
         the outstanding shares of capital stock of any such subsidiary was
         issued in violation of the preemptive or similar rights of any
         securityholder of such subsidiary.

                           (vii) This Reset Remarketing Agreement and the Reset
         Remarketing Agreement Supplement have been duly authorized, executed
         and delivered by the Company.

         (including, without limitation, all laws relating to fraudulent
         transfers, reorganization, moratorium or similar laws affecting
         enforcement of creditors' rights generally and except as enforcement
         thereof is subject to general principles of equity (regardless of
         whether enforcement is considered in a proceeding in equity or at
         law)(the "Bankruptcy Exceptions").

                           (ix) The issuance and delivery by the Company of the
         Collateral Bonds to the Trustee constitute a sale by the Company of the
         Collateral Bonds to the Trustee as of the Closing Date or, if not a
         sale, the grant by the Company to the Trustee of a perfected security
         interest in the Collateral Bonds for the benefit of the holders of the
         Senior Notes.

                           (x) The Secured Indenture constitutes a legally valid
         and direct enforceable first mortgage lien, except as the same may be
         limited by the laws of the State of Michigan (where all of the property

         of the security provided for therein, which laws do not make inadequate
         the remedies necessary for the realization of the benefits of such
         security, or as the same may be limited by the Bankruptcy Exceptions,
         upon substantially all of the Company's properties and franchises, now
         owned or hereafter acquired, free from all prior liens, charges or
         encumbrances, except as set forth in subparagraph (xviii) below, and
         except, in the case of property hereafter acquired, any thereof
         existing at the time of acquisition.

         executed by the Company and authenticated, issued and delivered in the
         manner provided for in the Indenture, and constitute valid and binding
         obligations of the Company, enforceable against the Company in
         accordance with their terms, except as the enforcement thereof may be
         limited by bankruptcy, insolvency (including, without limitation, all
         laws relating to fraudulent transfers), reorganization, moratorium or
         similar laws affecting enforcement of creditors' rights generally and
         except as enforcement thereof is subject to general principles of
         equity (regardless of whether enforcement is considered in a proceeding
         in equity or at law), and are in the form contemplated by, and entitled
         to the benefits of, the Indenture.

                           (xii) The Collateral Bonds have been duly authorized
         and executed by the Company and authenticated, issued, and delivered in
         the manner provided for in the Secured Indenture and have been issued
         and delivered to the Trustee as provided for in the Thirty-Fifth
         Supplemental Indenture as security for the Senior Notes, and constitute
         legal, valid and binding obligations of the Company, enforceable
         against the Company in accordance with their terms except to the extent
         that enforcement thereof may be limited by the Bankruptcy Exceptions.
         The Collateral Bonds are in the form contemplated by, and entitled to
         the benefits of, the Secured Indenture.

                           (xiii) Neither the Company nor any of its
         subsidiaries is in violation of its charter or by-laws or in default in
         the performance or observance of any material obligation, agreement,
         covenant or condition contained in any contract, indenture, mortgage,
         deed of trust, loan or credit agreement, note, lease or other agreement
         or instrument to which the

                                      -10-

         Company or any of its respective subsidiaries is a party or by which it
         or any of them may be bound, or to which any of the property or assets
         of the Company or any subsidiary is subject (collectively, "Agreements
         and Instruments") or in violation of any applicable law, rule or
         regulation or any judgment, order, writ or decree of any government,
         governmental instrumentality or court, domestic or foreign, having
         jurisdiction over the Company or any of its subsidiaries or any of
         their respective properties or assets, which violation or default
         would, singly or in the aggregate, have a Material Adverse Effect.

                           (xiv) The execution, delivery and performance of the
         Purchase Agreement, this Agreement, the Mandatory Tender Remarketing
         Agreement, the Indenture, the Senior Notes, the Thirty-Fifth
         Supplemental Indenture, the Collateral Bonds and any other agreement or
         instrument entered into or issued or to be entered into or issued by
         the Company in connection with the transactions contemplated hereby or
         thereby; and the consummation of the transactions contemplated herein
         and therein and compliance by the Company with its obligations
         hereunder and under the Indenture, the Secured Indenture, the
         Thirty-Fifth Supplemental Indenture, the Senior Notes, and the
         Collateral Bonds have been duly authorized by all necessary corporate
         action and do not and will not, whether with or without the giving of
         notice or passage of time or both, conflict with or constitute a breach
         of, or default or Repayment Event (as defined below) under, or result
         in the creation or imposition of any lien, charge or encumbrance upon
         any property or assets of the Company or any subsidiary pursuant to
         (other than the lien of the Indenture on the Collateral Bonds), the
         Agreements and Instruments (except for such conflicts, breaches or
         defaults or liens, charges or encumbrances that would not result in a
         Material Adverse Effect), nor will such action result in any violation
         of the provisions of the charter or by-laws of the Company or any
         subsidiary or any applicable law, statute, rule, regulation, judgment,
         order, writ or decree of any government, government instrumentality or
         court, domestic or foreign, having jurisdiction over the Company or any
         subsidiary or any of their assets, properties or operations. As used
         herein, a "Repayment Event" means any event or condition which gives
         the holder of any note, debenture or other evidence of indebtedness (or
         any person acting on such holder's behalf) the right to require the
         repurchase, redemption or repayment of all or a portion of such
         indebtedness by the Company or any subsidiary.

                           (xv) There is no action, suit, proceeding, inquiry or
         investigation before or brought by any court or governmental agency or
         body, domestic or foreign, now pending, or, to the knowledge of the
         Company, threatened, against or affecting the Company or any
         subsidiary, which is required to be disclosed in the 1934 Act Documents
         (other than as disclosed therein), or which might reasonably be
         expected to result in a Material Adverse Effect, or which might
         reasonably be expected to materially and adversely affect the
         properties or assets thereof or the consummation of the transactions
         contemplated in this Agreement or the performance by the Company of its
         obligations hereunder; the aggregate of all pending legal or
         governmental proceedings to which the Company or any subsidiary is a
         party or of which any of their respective property or assets is the
         subject which are not described in the 1934 Act Documents, including
         ordinary routine litigation incidental to the business, could not
         reasonably be expected to result in a Material Adverse Effect.

                           (xvi) No filing with, or authorization, approval,
         consent, license, order, registration, qualification or decree of, any
         court or governmental authority or agency is necessary or required for
         the performance by the Company of its obligations hereunder, in
         connection with the remarketing of the Senior Notes hereunder or the
         consummation of the transactions contemplated by this Agreement or for
         the due execution, delivery or performance of the Indenture by the
         Company, except such as have or shall have been already obtained.

                           (xvii) No labor dispute with the employees of the
         Company or any of its subsidiaries exists or, to the knowledge of the
         Company, is imminent, and neither the Company is aware of any existing
         or imminent labor disturbance by the employees of any of its or any of
         its subsidiary's principal suppliers, manufacturers, customers or
         contractors which, in either case, may reasonably be expected to result
         in a Material Adverse Effect.

                           (xviii) There are no contracts or documents which are
         required to be described in the Registration Statement, the Prospectus
         or the documents incorporated by reference therein or to be filed as
         exhibits thereto which have not been so described and/or filed as
         required.

                           (xix) The Company has good and marketable title to
         the properties specifically described in and conveyed by the Secured
         Indenture (except such property as may have been disposed of or
         released from the lien thereof in accordance with the terms thereof)
         subject only to the lien of the Secured Indenture, to permissible
         encumbrances, as defined in the Secured Indenture, as to property
         acquired by the Company subsequent to the execution of the Original
         Secured Indenture, to any liens existing thereon or purchase money
         liens placed thereon at the time of such acquisition as permitted by
         the Secured Indenture, and to certain other reservations, rights of
         grantors under revocable permits, easements, licenses, zoning laws and
         ordinances and restrictions and minor defects or irregularities of
         title which do not materially impair the use of the property affected
         thereby in the operation of the business of the Company; the Company
         and its subsidiaries have good and marketable title to all personal
         property owned by them, in each case free and clear of all liens,
         encumbrances and defects except the liens of the Secured Indenture and
         such liens, encumbrances and defects as do not materially affect the
         value of such property and do not interfere with the use made and
         proposed to be made of such property by the Company and its
         subsidiaries; and any real property and buildings held under lease by
         the Company and its subsidiaries are held by them under valid,
         subsisting and enforceable leases with such exceptions as are not
         material and do not interfere with the use made and proposed to be made
         of such property and buildings by the Company and its subsidiaries; the
         pipeline, distribution main and underground gas storage easements
         enjoyed by the Company and its subsidiaries are valid, subsisting and
         enforceable easements with such exceptions as are not material and do
         not interfere with the conduct of the business of the Company and its
         subsidiaries.

                           (xx) The Company and its subsidiaries possess all
         licenses, franchises, permits, certificates, authorizations, approvals,
         consents, orders and other operating rights (collectively, the
         "Governmental Licenses") issued by the Federal Energy Regulatory

         Commission, the State of Michigan, and all other federal, state, local
         or foreign regulatory agencies or bodies, governmental authorities or
         agencies necessary for the ownership or lease of the material
         properties owned or leased by each of them and to conduct the business
         now operated by each of them; the Company and its subsidiaries are in
         compliance with the terms and conditions of all such Governmental
         Licenses, except where the failure to so comply would not, singly or in
         the aggregate, have a Material Adverse Effect; all of the Governmental
         Licenses are valid and 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 and the Prospectus, there are no legal or governmental
         proceedings pending or threatened that would result in a material
         modification, suspension or revocation thereof.

                           (xxi) Except as described in any Reset Remarketing
         Materials and except as would not, singly or in the aggregate, result
         in a Material Adverse Effect, (A) neither the Company nor any of its
         subsidiaries is in violation of any federal, state, local or foreign
         statute, law, rule, regulation, ordinance or code, including any
         judicial or administrative order, consent, decree or judgment, relating
         to pollution or protection of human health, the environment (including,
         without limitation, ambient air, surface water, groundwater, land
         surface or subsurface strata) or wildlife, including, without
         limitation, laws and regulations relating to the release or threatened
         release of chemicals, pollutants, contaminants, wastes, toxic
         substances, hazardous substances, petroleum or petroleum products
         (collectively, "Hazardous Materials") or to the manufacture,
         processing, distribution, use, treatment, storage, disposal, transport
         or handling of Hazardous Materials (collectively, the "Environmental
         Laws"), (B) the Company and its subsidiaries have all permits,
         authorizations and approvals required under any applicable
         Environmental Laws and are in compliance with their requirements, and
         (C) there are no pending or threatened administrative, regulatory or
         judicial actions, suits, demands, demand letters, claims, liens,
         notices of noncompliance or violation, investigation or proceedings
         relating to any Environmental Law against the Company or any of its
         subsidiaries.

                           (xxii) The Company is a "public utility company" and
         a "subsidiary company" of MCN Energy Group, a "holding company," as
         such terms are defined in the Public Utility Holding Company Act of
         1935 (the "1935 Act"), and such "holding company" and the Company are
         presently exempt from the provisions of the 1935 Act (except Section 9
         thereof).

                           (xxiii) The Company has complied with, and is and
         will be in compliance with, the provisions of that certain Florida act
         relating to disclosure of doing business with Cuba, codified as Section
         517.075 of the Florida statutes, and the rules and regulations
         thereunder (collectively, the "Cuba Act") or is exempt therefrom.

                           (xxiv) None of the Company and its subsidiaries or
         any of their respective directors, officers or controlling persons, has
         taken or 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 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 remarketing of the Senior Notes.

                           (xxv) 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.

                           (xxvi) The Company is not an "investment company" or
         an entity "controlled" by an "investment company" as such terms are
         defined in the Investment Company Act of 1940, as amended.

                           (xxvii) The Senior Notes are rated "A2" by Moody's
         Investors Service, Inc. and "A" by Standard & Poor's Rating Services, a
         division of the McGraw-Hill Companies, Inc. or such other rating as to
         which the Company shall have most recently notified the Reset
         Remarketing Agent pursuant to Section 3(a) hereof.

         References in the foregoing representations and warranties to the 1934
Act Documents shall be deemed to refer to the Registration Statement (as defined
in Section 5(b) below) and Prospectus (as defined in Section 5(b) above), in
each case including the documents incorporated by reference therein, if such are
required pursuant to such Section 5(b).

                  Section 8. Conditions to the Reset Remarketing Agent's
Obligations. The obligations of the Reset Remarketing Agent under this Agreement
have been undertaken in reliance on, and shall be subject to,

                  (a) the due performance by the Company of its obligations and
agreements as set forth in this Agreement and the accuracy of the
representations and warranties in this Agreement and any certificate delivered
pursuant hereto, and

                  (b) the further condition that none of the following events
shall have occurred at any time:

                           (i) the rating of any securities of the Company shall
         have been down-graded or put under surveillance or review, including
         being put on CreditWatch or Watch List with negative implications, or
         withdrawn by a nationally recognized statistical rating organization;

                           (ii) without the prior written consent of the Reset
         Remarketing Agent, neither the Indenture (including the Senior Notes)
         nor the Secured Indenture (including the Collateral Bonds) shall have
         been amended in any manner, or otherwise contain any provision not
         contained therein as of the date hereof, that in either case in the
         judgment of the Reset Remarketing Agent materially and adversely
         changes the nature of the Senior Notes or the Collateral Bonds, as the
         case may be, or the remarketing procedures (it being understood that,
         notwithstanding the provisions of this clause (ii), the Company shall
         not be prohibited from amending the Indenture);

                           (iii) trading in any securities of the Company or any
         of its affiliates shall have been suspended or materially limited by
         the Commission or the New York Stock Exchange, or if trading generally
         on the American Stock Exchange or the New York Stock Exchange or in the
         Nasdaq National Market shall have been suspended or materially limited,
         or minimum or maximum prices for trading shall have been fixed, or
         maximum ranges for prices shall have been required, by any of said
         exchanges or by such system or by order of the Commission, the National
         Association of Securities Agents, Inc. or any other governmental
         authority, or if a banking moratorium shall have been declared by
         either Federal or New York authorities;

                           (iv) there shall have occurred any material adverse
         change in the financial markets in the United States or the
         international financial markets, any outbreak of hostilities or
         escalation thereof or other calamity or crisis or any change or
         development involving a prospective change in national or international
         political, financial or economic conditions, in each case the effect of
         which is such as to make it, in the judgment of the Reset Remarketing
         Agent, impracticable to remarket the Senior Notes or to enforce 
         contracts for the sale of the Senior Notes;

                           (v) an Event of Default (as defined in the
         Indenture), or any event which, with the giving of notice or passage of
         time, or both, would constitute an Event of Default, with respect to
         the Senior Notes shall have occurred and be continuing;

                           (vi) 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, whether or not arising in the ordinary course of
         business, shall have occurred; or

                           (vii) the Senior Notes are not maintained in
         book-entry form with DTC or any successor thereto; provided, that the
         Reset Remarketing Agent, in its sole discretion and subject to receipt
         of an opinion of counsel for the Company reasonably satisfactory to the
         Reset Remarketing Agent, may waive the foregoing condition if in the
         Reset Remarketing Agent's judgment the Indenture and the Senior Notes
         can be amended, and they are amended, so as to permit the remarketing
         of the Senior Notes in certificated form and otherwise as contemplated
         herein;

                  (c) The obligations of the Reset Remarketing Agent to purchase
and remarket the Senior Notes shall also be subject to the terms and conditions
of the applicable Reset Remarketing Agreement Supplement.

                  Section 9. Indemnification. (a) The Company agrees to
indemnify and hold harmless the Reset Remarketing Agent and its officers,
directors and employees and each person, if any, who controls the Reset
Remarketing Agent within the meaning of Section 20 of the 1934 Act as follows:

                           (i) against any loss, liability, claim, damage or
         expense whatsoever (collectively, "Damages"), as incurred, arising out
         of, (A) the failure to have an effective

         Registration Statement under the 1933 Act relating to the Senior Notes,
         if required, or the failure to satisfy the prospectus delivery
         requirements of the 1933 Act because the Company failed to provide the
         Reset Remarketing Agent with a Prospectus for delivery, as required by
         Section 5 hereof, or (B) any untrue statement or alleged untrue
         statement of a material fact contained in any of the Reset Remarketing
         Materials (including any incorporated documents), or (C) the omission
         or alleged omission therefrom of a material fact necessary to make the
         statements therein, in the light of the circumstances in which they
         were made, not misleading, or (D) any violation by the Company of, or
         any failure by the Company to perform any of its obligations under,
         this Agreement, or (E) the acts or omissions of the Reset Remarketing
         Agent in connection with its duties and obligations to determine the
         Interest Rate or other terms with respect to any Subsequent Spread
         Period, as provided hereunder, except Damages that are finally
         judicially determined to be due to its gross negligence or willful
         misconduct;

                           (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 investigation
         or proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever arising out of, or based upon,
         any of items (A) through (E) in clause (i) above; provided that
         (subject to clause (d) below) such settlement is effected with the
         written consent of the Company, which consent shall not be unreasonably
         withheld; and

                           (iii) against any and all expense whatsoever, as
         incurred (including the fees and disbursements of counsel chosen by the
         Reset Remarketing Agent), 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 arising out of, or based upon, any of items (A)
         through (E) in clause (i) above to the extent that any such expense is
         not paid under (i) or (ii) above;

provided, however, that the foregoing indemnity shall not apply to any losses,
liabilities, claims, damages and expenses to the extent arising out of any
untrue statement or omission made in reliance upon and in conformity with
written information furnished to the Company by the Reset Remarketing Agent
expressly for use in the Reset Remarketing Materials.

                  (b) 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 clause (a) above, counsel to the indemnified
parties shall be selected by Merrill Lynch, and, in the case of parties
indemnified pursuant to clause (b) above, counsel to the indemnified parties
shall be selected by the Company. An indemnifying party may participate at its
own expense in the defense of any such action; provided, however, that counsel
to the indemnifying party shall not (except with the consent of the indemnified
party) also be counsel to the indemnified party. In no event shall the
indemnifying parties be liable for fees and expenses of more than one counsel
(in addition to any





                                      -16-

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 9 or Section 10 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
or fault, culpability or a failure to act by or on behalf of any indemnified
party.

                  (c) 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 clause 9 (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.

                  (d) The indemnity agreements contained in this Section 10
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the Reset Remarketing Agent, and shall
survive the termination or cancellation of this Agreement and the remarketing of
any Senior Notes hereunder.

                  Section 10. Contribution. If the indemnification provided for
in Section 9 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of any losses, liabilities, claims,
damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Reset Remarketing Agent on the other hand from
the remarketing of the Senior Notes pursuant to this Agreement or (ii) if the
allocation provided by clause (i) is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company on the one
hand and of the Reset Remarketing Agent on the other hand in connection with the
acts, failures to act, statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

                  The relative benefits received by the Company on the one hand
and the Reset Remarketing Agent on the other hand in connection with the
remarketing of the Senior Notes pursuant to this Agreement shall be deemed to be
in the same respective proportions as (i) the aggregate principal amount of the
Senior Notes, and (ii) the aggregate positive difference, if any, between the
price at which the Senior Notes are sold by the Reset Remarketing Agent in the
remarketing and the price paid by the Reset Remarketing Agent for the Senior
Notes tendered on any Reset Tender Date.

                  The relative fault of the Company on the one hand and the
Reset Remarketing Agent on the other hand shall be determined by reference to,
among other things, the responsibility hereunder of the applicable party for any
act or failure to act relating to the losses, liabilities, claims, damages or
expenses incurred or, in the case of any losses, liabilities, claims, damages or
expenses arising out of any untrue or alleged untrue statement of a material
fact contained in any of the Reset Remarketing Materials or the omission or
alleged omission to state a material fact therefrom, whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Company or by the
Reset Remarketing Agent and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

                  The Company and the Reset Remarketing Agent agree that it
would not be just and equitable if contribution pursuant to this Section 10 were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to above in this
Section 10. The aggregate amount of losses, liabilities, claims, damages and
expenses incurred by an indemnified party and referred to above in this Section
10 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 act
or failure to act or untrue or alleged untrue statement or omission or alleged
omission.

                  Notwithstanding the provisions of this Section 10, the Reset
Remarketing Agent shall not be required to contribute any amount in excess of
the amount by which the total price at which the Senior Notes remarketed by it
and resold to the public were sold to the public exceeds the amount of any
damages which the Reset Remarketing Agent has otherwise been required to pay by
reason of any act or failure to act for which it is responsible hereunder or any
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 11, each person, if any, who
controls the Reset Remarketing Agent 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 Reset Remarketing Agent, and each officer and director of
the Company who signed the Registration Statement, and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act shall have the same rights to contribution as the Company.

                  Section 11. Termination of this Reset Remarketing Agreement.
Subject to Section 3 hereof relating to the payment of fees and expenses, this
Agreement shall terminate as to the Reset Remarketing Agent on the effective
date of the removal of such Reset Remarketing Agent pursuant to Section 4
hereof.

                  Section 12. Reset Remarketing Agent's Performance: Duty of
Care. The duties and obligations of the Reset Remarketing Agent hereunder shall
be determined solely by the express




                                      -18-

provisions of this Agreement, the Senior Notes and the Indenture, the Secured
Indenture and the Collateral Bonds and the applicable Reset Remarketing
Agreement Supplement. No implied covenants or obligations of or against the
Reset Remarketing Agent shall be read into this Agreement, the Indenture or the
Secured Indenture. In the absence of bad faith on the part of the Reset
Remarketing Agent, the Reset Remarketing Agent may conclusively rely upon any
document furnished to it, which purports to conform to the requirements of this
Agreement, the Indenture, or the Secured Indenture, as to the truth of the
statements expressed in any of such documents. The Reset Remarketing Agent shall
be protected in acting upon any document or communication reasonably believed by
it to have been signed, presented or made by the proper party or parties. The
Reset Remarketing Agent shall incur no liability hereunder to any Beneficial
Owner or Holder of Senior Notes in its individual capacity or as Reset
Remarketing Agent for any action or failure to act in connection with the
remarketing or otherwise. The Reset Remarketing Agent shall incur no liability
to the Company with respect to calculation of the Interest Rate applicable to
any Interest Period, except as a result of gross negligence or willful
misconduct on its part.

                  Section 13. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO

Senior Notes are outstanding.

of the Company hereunder may not be assigned or delegated to any other person
without the prior written consent of Merrill Lynch, the rights and obligations
of Merrill Lynch hereunder may not be assigned or delegated to any other person
without the prior written consent of the Company, and any attempt by either
party to do so will be unenforceable. This Agreement shall inure to the benefit
of and be binding upon the Company and Merrill Lynch and their respective
permitted successors and assigns. The terms "successors" and "assigns" shall not
include any purchaser of any Senior Notes merely because of such purchase.

                  Section 16. Headings. Section headings have been inserted in
this Agreement as a matter of convenience of reference only, and it is agreed
that such section headings are not a part of this Agreement and will not be used
in the interpretation of any provisions of this Agreement.

                  Section 17. Severability. If any provision of this Agreement
shall be held or deemed to be or shall, in fact, be invalid, inoperative or
unenforceable as applied in any particular case in any or all jurisdictions
because it conflicts with any provision of any constitution, statute, rule or
public policy or for any other reason, such circumstances shall not have the
effect of rendering the provision in question invalid, inoperative or
unenforceable in any other case, circumstances or jurisdiction, or of rendering
any other provision or provisions of this Agreement invalid, inoperative or
unenforceable to any extent whatsoever.

                     RESET REMARKETING AGREEMENT SUPPLEMENT

                  Merrill Lynch & Co./ Merrill Lynch, Pierce, Fenner & Smith
Incorporated (the "Reset Remarketing Agent") hereby agrees to purchase the
Senior Notes described below (the "Senior Notes") that have been tendered by the
holders thereof for sale on _____________, _____ (the "Reset Tender Date").

                  It is acknowledged and agreed that the Senior Notes need not
be further registered under the Securities Act of 1933, as amended (the "Act"),
and that, in connection with the remarketing of the Senior Notes by the Reset
Remarketing Agent in accordance with the terms of the Reset Remarketing
Agreement dated as of June 23, 1998, no prospectus meeting the requirements of
Section 10 of the Act need be delivered, or filed pursuant to Rule 424 under the
Act.

                  It is understood that the Reset Remarketing Agent will deliver
to purchasers and prospective purchasers, in connection with the remarketing,
one or more forms of written communication describing the terms of the Senior
Notes (each, a "Reset Remarketing Memorandum"), the form of each of which shall
be delivered to Michigan Consolidated Gas Company, a Michigan corporation (the
"Company"), not less than two Business Days prior to its use and subject to the
approval of the Company prior to its use by the Reset Remarketing Agent, which
approval shall not be unreasonably withheld or delayed.

                  The Reset Remarketing Agent shall offer to purchase Senior
Notes and purchase validly tendered Senior Notes on the Reset Tender Date in
accordance with all applicable laws and regulations and interpretations of the
Securities and Exchange Commission.

                  The representations and warranties made pursuant to the
above-referenced Reset Remarketing Agreement (other than paragraphs (b)(viii),
(x), (xi) and (xii) of Section 7); Section 3(o) of the attached Purchase
Agreement (which date shall be the date of the Reset Remarketing Agreement
Supplement and the relevant Reset Tender Date); Section 9 of the attached
Purchase Agreement (except that Section 9 is amended to allow termination of
this Agreement by the Agent if the Company's representations and warranties
therein are not accurate and correct); paragraphs (c) and (f) of Section 5 of
the attached Purchase Agreement; and Section 8 and the last paragraph of Section
5 of the attached Purchase Agreement are incorporated in their entirety into
this Agreement and made applicable to the obligations of the Reset Remarketing
Agent to the extent applicable to any remarketing of the Senior Notes, except as
explicitly amended hereby. The terms "Registration Statement" and "Prospectus"
shall be deemed to refer to each such document as amended to the date hereof and
the Reset Tender Date, and the term "Incorporated Documents" shall similarly be
deemed to include those filed and incorporated by reference through such dates.

                  If the Reset Remarketing Agent determines, based on advice of
counsel, that changes in applicable law, regulations or interpretations of the
Securities and Exchange Commission make it necessary or advisable to deliver a
current prospectus in connection with this Remarketing, the attached Purchase
Agreement shall apply in its entirety. All references in such Purchase Agreement
to (i) the "Agent" shall be deemed to refer to the Reset Remarketing Agent, (ii)
the "Securities" shall





<PAGE>   23

be deemed to refer to the Senior Notes, (iii) the Purchase Agreement shall be
deemed to refer to the Reset Remarketing Agreement Supplement, and (iv) "Closing
Date" shall be deemed to refer to the Reset Tender Date. To the extent the
provisions of such Purchase Agreement refer to the "Prospectus" or the
"Registration Statement," such references shall be deemed to refer to any
Remarketing Memorandum or registration statement, if any, that the Company is
required to prepare or file pursuant to applicable law, regulations or
interpretations of the Securities and Exchange Commission in effect at the time
of such remarketing of the Senior Notes, including all documents incorporated by
reference therein. For the purposes of Section 7 of the attached Purchase
Agreement, the relative benefit received by the Company on the one hand and the
Reset Remarketing Agent on the other in connection with the remarketing of the
Senior Notes pursuant to this Agreement shall be deemed to be in the same
respective proportions as the aggregate public offering price of the Senior
Notes bears to the remarketing fee received by the Reset Remarketing Agent
pursuant to this Agreement.

                  All capitalized terms not otherwise defined in this Agreement
have the respective meanings assigned thereto in the Senior Notes, the form of
which is attached hereto.
