Ladies and Gentlemen:

         Michigan Consolidated Gas Company (the "COMPANY"), a Michigan

Co., L.P. (the "UNDERWRITER"), with respect to the issue and sale by the Company
and the purchase by the Underwriter, acting severally and not jointly, of the
principal amount set forth in Schedule II of $55,000,000 aggregate principal
amount of the Company's 6.85% Senior Secured Insured Quarterly Notes due 2038

Base Indenture (the "SECOND SUPPLEMENTAL INDENTURE," and together with the Base
Indenture and any amendments or supplements thereto, the "INDENTURE") to be
entered into between the Company and the Trustee, which will be secured by the
concurrent issuance and delivery to the Trustee of the Company's First Mortgage
Bonds, Collateral Series C (the "COLLATERAL BONDS"), issued under and ratably
secured by the Indenture of Mortgage and Deed of Trust dated as of March 1, 1944
(the "ORIGINAL SECURED INDENTURE"), as supplemented and amended by thirty-five
indentures supplemental thereto, including specifically the Twenty-ninth
Supplemental Indenture, and the Thirty-fifth Supplemental Indenture creating the
series in which the Collateral Bonds are to be issued (the "THIRTY-FIFTH
SUPPLEMENTAL INDENTURE") (the Original 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

         The Company has filed with the Securities and Exchange Commission (the
"COMMISSION") a registration statement on Form S-3 (No. 333-56333) covering the

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,

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

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

Agreement to amendments or supplements to the Registration Statement, any

stated therein or necessary to make the statements therein not misleading.
Neither the Prospectus nor any amendments or supplements thereto, at the time
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

Notwithstanding the foregoing, the representations and warranties in this
subsection shall not apply to statements in or omissions from the Registration
Statement or the Prospectus made in reliance upon and in conformity with
information furnished to the Company in writing by any Underwriter through the
Underwriter expressly for use in the Registration Statement or the Prospectus.

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

which could reasonably be expected to result in a material adverse change in the

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

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

Material Adverse Effect.

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

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.

delivered by the Company.

                  (xi) The Securities have been duly authorized for issuance and

                                       -5-


<PAGE>   6


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 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

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 Securities.

                  (xv) 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 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

                                       -6-

judgment, order, writ or decree of any government, governmental instrumentality
or court, domestic or foreign, having jurisdiction over the Company or any of

of this Agreement, the Indenture, the Securities, the 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

Prospectus (including the issuance and sale of the Securities and the issuance
and delivery 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

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) 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


                                       -7-

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 Underwriter 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

Registration Statement, Term Sheet, amendment, supplement or revision a

Securities, any event shall occur or condition shall exist as a result of which
it is necessary, in the opinion of counsel for the Underwriter 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

of such amendment or supplement as the Underwriter may reasonably request.

         (g) The Company will use its best efforts, in cooperation with the
Underwriter, to qualify the Securities for offering and sale under the
applicable securities laws of such states and other jurisdictions (domestic or
foreign) as the Underwriter 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,

as are necessary in order to make generally available to its securityholders and

Act Regulations, then immediately following the execution of this Agreement, the
Company will prepare, and file or transmit for filing with the Commission in

of the 1934 Act Regulations.

         (o) During a period of fifteen days from the date of the Prospectus,
the Company will not, without the prior written consent of the Underwriter,
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
the Underwriter, except for the offer by the Company of $55,000,000 aggregate
principal amount of its 6.85% Senior Notes due June 1, 2039.

         (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.

         foreign corporation to transact business and is in good standing in

         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

         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 Securities.

                                 (viii) Except as to property acquired
         subsequent to the date of execution of the Thirty-fifth 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



                                      -17-

         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 (A) the Secured Indenture and the issuance and
         delivery of the Collateral Bonds and (B) the Indenture and the issuance
         and delivery of the Securities, 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
         by the Company, directly or through its subsidiaries and, to the best
         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.

         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 knowledge of such counsel, 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

         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

         thereof by the Trustee, constitutes a valid and legally binding

         Company or its subsidiaries is subject, except for such conflicts,
         breaches, defaults, 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 or by-laws of the Company or any if its subsidiaries, or any

         Securities and the sale of the Securities in accordance with this

         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

         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.

         not, singly or in the aggregate, materially affect the value of such
         property and do not materially interfere with the use made and proposed

         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.

                                 (xxviii) The Company is not an "investment
         company" or an entity under the "control" of an "investment company" as

         from the provisions of the Public Utility Holding Company Act of 1935

         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

         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

         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.

         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,

                  statements set forth in the Company's Quarterly Reports on

                  generally accepted accounting principles applied on a basis
                  substantially consistent with that of the audited consolidated

         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,

         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

"nationally recognized statistical rating organization"



                                      -26-

(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

         (g) On the Closing Date, the Underwriter shall have received from Kutak
Rock, counsel to the Insurer, an opinion substantially in the form attached
hereto as Schedule III.

         (h) On the Closing Date, the Underwriter shall have received a
certificate of an appropriate officer of the Insurer, dated as of the Closing
Date, to the effect that the information being presented in the Prospectus
Supplement is true and accurate in all material respects with respect to the
Insurer, that there is no pending litigation against the Insurer that would
materially affect the Insurer's ability to perform its obligations, and that all
necessary corporate action has been take with respect to the execution, delivery
and performance of the Insurance Policy, and that the execution and delivery of
the Insurance Policy do not conflict with the organizational documents of the
Insurer.

         (i) On the Closing Date, counsel for the Underwriter shall have been

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

         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 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



                                      -27-
<PAGE>   28

         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
         the Underwriter), 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 the Underwriter 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 Underwriter (or any person controlling such
Underwriter) from whom the person asserting any such loss, liability, claim,
damage or expense purchased any of the Securities 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



                                      -28-
<PAGE>   29

Section 20 of the 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 the
Underwriter 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 the Underwriter, 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



                                      -29-
<PAGE>   30

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 Underwriter 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 Underwriter 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
Underwriter 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 Underwriter, 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 Underwriter
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 Underwriter and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

         The Company and the Underwriter 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 Underwriter 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.



                                      -30-
<PAGE>   31

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

         SECTION 9.  Termination of Agreement.

         (a) The Underwriter 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 Underwriter, 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




                                      -31-
<PAGE>   32

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

the Trustee, which will be secured by the concurrent issuance and delivery to
the Trustee of the Company's First Mortgage Bonds, Collateral Series D (the

Mortgage and Deed of Trust


<PAGE>   2

dated as of March 1, 1944 (the "ORIGINAL SECURED INDENTURE"), as supplemented
and amended by thirty-five indentures supplemental thereto, including
specifically the Twenty-ninth Supplemental Indenture, and the Thirty-fifth
Supplemental Indenture creating the series in which the Collateral Bonds are to
be issued (the "THIRTY-FIFTH SUPPLEMENTAL INDENTURE") (the Original 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 proposes to
sell to the Underwriters Securities of the designation, with the terms and the
aggregate principal amount specified in Schedule I hereto.

         The Company has filed with the Securities and Exchange Commission (the
"COMMISSION") a registration statement on Form S-3 (No. 333-56333) covering the

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

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

its subsidiaries, considered as one enterprise (a "MATERIAL ADVERSE EFFECT"),
whether or not arising in the ordinary course of business, (B) there have been

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.

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

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

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

enforceable against the Company in accordance with their terms 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

will cause the Prospectus, including as a part thereof a prospectus supplement
relating to the Securities and the Collateral Bonds, to be filed with the
Commission pursuant to Rule 424(b) of the 1933 Act Regulations and will take

prospectus.

         (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 Underwriters immediately, and confirm the notice
in writing, (i) of the effectiveness of any post-effective amendment to the
Registration Statement or the filing of any supplement or amendment to the
Prospectus, (ii) of 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 Underwriters 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 Underwriters with copies of any such Rule 462(b)
Registration Statement, Term Sheet, amendment, supplement or revision a
reasonable amount of time prior to such proposed filing or use, as the case may
be; and will not file any such Rule 462(b) Registration Statement, Term Sheet,
amendment, supplement or revision to which the Underwriters or counsel for the
Underwriters shall object.

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

                                      -12-

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

         (e) The Company will deliver to each Underwriter, without charge, as
many copies of each preliminary prospectus as such Underwriter may reasonably
request, and the Company hereby consents to the use of such copies for purposes
permitted by the 1933 Act. The Company will furnish to each Underwriter, without
charge, during the period when the Prospectus is required to be delivered under
the 1933 Act or the 1934 Act, such number of copies of the Prospectus (as

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 Underwriters 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.

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
this Agreement and (ii) the time confirmations are sent or given, as specified
by Rule 462(b)(2).

         (m) The Company, during the period when the Prospectus is required to
be delivered under the 1933 Act or the 1934 Act, will file all documents
required to be filed with the Commission pursuant to Section 13, 14 or 15 of the
1934 Act within the time periods required by the 1934 Act and the 1934 Act

or agreements with such exchange or to the Commission pursuant to the 1934 Act
of the 1934 Act Regulations.

         (o) During a period of fifteen days from the date of the Prospectus,
the Company will not, without the prior written consent of Merrill Lynch,
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
Merrill Lynch,

directors, officers or controlling persons, will take, directly or indirectly,

         (b) On the Closing Date the Underwriters shall have received:

                  (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



                                      -16-

         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 under the Secured Indenture in the manner
         provided for in the Secured 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 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 Securities.

                                 (viii) Except as to property acquired
         subsequent to the date of execution of the Thirty-fifth 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



                                      -17-

         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 (A) the Secured Indenture and the issuance and
         delivery of the Collateral Bonds and (B) the Indenture and the issuance
         and delivery of the Securities, 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
         by the Company, directly or through its subsidiaries and, to the best
         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.

         thereof by the Trustee, constitutes a valid and legally

         connection with the authorization, issuance and validity of the
         Securities and the sale of the Securities in accordance with this

         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

         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;

         its subsidiaries are held by them under valid, subsisting and
         enforceable leases with such exceptions as are not material and do not

                                 (xxviii) 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.

                                 (xxix) 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 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
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 Underwriters, with respect to such
matters as the Underwriters 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.

         (c) On the Closing Date, the Underwriters shall have received a
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
Closing Date, to the effect that (i) there has been no 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 in the ordinary course of business, (ii) the
representations and warranties in Section 1 hereof are true and correct with the
same force and effect as though expressly made at and as of the Closing Date,
(iii) the Company has complied with all



                                      -23-
<PAGE>   24

agreements and satisfied all conditions on its part to be performed or satisfied
on or prior to the Closing Date, and (iv) no stop order suspending the
effectiveness of the Registration Statement has been issued and no proceedings
for that purpose have been initiated or threatened by the Commission.

         (d) At the time of the execution of this Agreement, the Underwriters
shall have received from Deloitte & Touche LLP a letter dated such date in form
and substance satisfactory to the Underwriters, together with signed or
reproduced copies of such letter for each of the other Underwriters, to the
effect set forth below and as to such other matters as the Underwriters may
reasonably request, that:

                  (i)    They are independent certified public accountants with
         respect to the Company and its subsidiaries within the meaning of the
         1933 Act and the 1933 Act Regulations;

                  (ii)   In their opinion, the consolidated financial statements
         and any financial statement schedules audited by them and included or
         incorporated by reference in the Registration Statement and the
         Prospectus, as amended or supplemented, 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;

                  (iii)  On the basis of limited procedures, not constituting an
         audit in accordance with generally accepted auditing standards,
         including a review in accordance with standards established by the
         American Institute of Certified Public Accountants of the unaudited
         condensed consolidated financial statements included in the Company's
         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
         available unaudited interim consolidated financial statements 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
                  Form 10-Q incorporated by reference in the Registration
                  Statement and the Prospectus as amended or supplemented do not
                  comply as to form in all material respects with the applicable
                  accounting requirements of the 1934 Act 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

                  amended or supplemented;

                           (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;

                           (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

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

                  Underwriters, in each case as compared with the corresponding
                  period in the preceding year and with any other period of
                  corresponding length specified by



                                      -25-

                  the Underwriters, except in each case for increases or
                  decreases which the Prospectus, as amended or supplemented,
                  including financial information incorporated by reference,

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

         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,

         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

they reaffirm the statements made



                                      -26-

         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 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



                                      -28-
<PAGE>   29

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 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



                                      -29-
<PAGE>   30

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 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 Underwriters 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 Underwriters, 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) The Underwriters may terminate this Agreement, by notice to the
Company at any time on or prior to the Closing Date, if there has been, since
the date of this Agreement or since the respective dates as of which information
is given in the Prospectus, any change or any development which would materially
and adversely affect the Insurer's condition (financial or otherwise) or
operations or which would materially and adversely affect the Insurer's ability
to perform its obligations under the Insurance Policy.

         (c) 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 Underwriters 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 Underwriters shall not have completed such arrangements
within



                                      -32-
<PAGE>   33

such 24-hour period, then 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 Underwriters 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 Merrill Lynch & Co. at World Financial Center

successors. Nothing expressed or mentioned in this Agreement is intended or
shall be construed to give any person, firm or corporation, other than the

                          TRANSFER OF COLLATERAL BONDS

         The Company hereby issues, delivers and transfers to the Trustee (A) in
connection with the issuance of the Senior Secured Insured Quarterly Notes,
Fifty-Five Million Dollars ($55,000,000) aggregate principal amount of a related
issue of Collateral Bonds of the Company designated "First Mortgage Bonds,
Collateral Series C" and (B) in connection with the issuance of the Senior
Notes, Fifty-Five Million Dollars ($55,000,000) aggregate principal amount of a
related issue of Collateral Bonds of the Company designated "First Mortgage

which has been fully registered in the name of the Trustee in such capacity, to
be held in trust for the benefit of the Holders from time to time of the Related
Issue of Securities and, if such transfer does not constitute a sale of the
Collateral Bonds to the Trustee, the Company hereby grants a perfected security
interest in the Collateral Bonds for the benefit of such Holders, in each case
as security for any and all obligations of the Company under the Indenture, this
Supplemental Indenture and the Related Issue of Securities, including but not
limited to (1) the full and prompt payment of the interest on, principal of, and
premium, if any, on the Securities when and as the same shall become due and

as the same shall become due and payable in accordance with the terms and
provisions of the Indenture and this Supplemental Indenture or the Related Issue
of Securities. The Trustee shall enforce all of its rights under the First
Mortgage Indenture as a holder of the Related Issue of Collateral Bonds
transferred to it as provided in this Article III for the benefit of the Insurer
and the Holders of the Related Issue of Securities and the proceeds of the
enforcement of such rights shall be applied by the Trustee to satisfy the
Company's obligations under the Indenture, this Supplemental Indenture, and the
Related Issue of Securities.

         The Company shall make payments of the principal of, and premium or
interest on, the Collateral Bonds to the Trustee, which payments shall be
applied by the Trustee to satisfaction of all obligations then due on the
Related Issue of Securities.

         The Collateral Bonds shall not be sold or transferred by the Trustee
until the earlier of the Release Date or the prior retirement of the Securities
through redemption, repurchase or otherwise. The "Release Date" shall be the
date that all First Mortgage Bonds of the Company issued and outstanding under
the First Mortgage Indenture, other than the Collateral Bonds (as defined in the
Senior Indenture) 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, at such time, is continuing under the Indenture.

         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

States, and to pay interest thereon from the Original Issue Date shown above, or
from the most recent Interest Payment Date to which interest has been paid or
duly provided for, quarterly in arrears on each Interest Payment Date as

lawful manner not inconsistent with the requirements of any securities exchange,
if any, on which the securities of this series shall be listed, and upon such

Interest payments for this Senior Secured Insured Quarterly Note shall be
computed and paid on the basis of a 360-day year of twelve 30-day months. In the
event that any date on which interest is payable on this Senior Secured Insured
Quarterly Note is not a business Day, then payment of the interest payable on
such date will be made on the next succeeding day that is a Business Day (and
without any interest or payment in respect of any such delay) with the same
force and effect as if made on the date the payment was originally payable.
"Business Day" means a day other than (i) a Saturday or a Sunday, (ii) a day on
which banking institutions in New York, New York are authorized or obligated by
law or executive order to remain closed or (iii) a day on which the Corporate
Trust Office is closed for business.

         Payment of principal of, premium, if any, and interest on the

transfer of immediately available funds to the Holder of such Global Security,
provided that, in the case of payments of principal and premium, if any, such
Global Security is first surrendered to the Paying Agent (as defined in the
Senior Indenture). If any of the securities of this series are not longer
represented by a Global Security, (i) payments of principal, premium, if any,
and interest due at the Stated Maturity or earlier redemption of such Securities
shall be made at the office of the Paying Agent upon surrender of such
Securities to the Paying Agent, and (ii) payments of interest shall be made, at
the option of the Company, subject to such surrender where applicable, (A) by
check mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register or (B) by wire transfer at such place and to
such account at a banking institution in the United States as may be designated
in writing to the Trustee at least sixteen (16) days prior to the date for
payment by the Person entitled thereto.

         UNTIL THE RELEASE DATE (AS DEFINED ON THE REVERSE HEREOF), THIS SENIOR
SECURED INSURED QUARTERLY NOTE SHALL BE SECURED BY FIRST MORTGAGE BONDS (THE
"FIRST MORTGAGE BONDS") ISSUED AND DELIVERED BY THE COMPANY TO THE SENIOR
TRUSTEE (AS DEFINED ON THE REVERSE HEREOF) UNDER THE COMPANY'S TWENTY-NINTH
SUPPLEMENTAL INDENTURE DATED AS OF JULY 15, 1989, PROVIDING FOR THE RESTATEMENT
OF THE INDENTURE OF MORTGAGE AND DEED OF TRUST DATED AS OF MARCH 1, 1994 BETWEEN
THE COMPANY AND CITIBANK, N.A. (THE "MORTGAGE TRUSTEE") AND ROBERT T. KIRCHNER

INDENTURE (AS SO SUPPLEMENTED, THE "MORTGAGE INDENTURE"). ON THE RELEASE DATE,
THE SENIOR SECURED INSURED QUARTERLY NOTES SHALL CEASE TO BE SECURED BY SUCH
FIRST MORTGAGE BONDS AND, AT THE COMPANY'S OPTION, EITHER (i) SHALL BECOME
UNSECURED GENERAL OBLIGATIONS OF THE COMPANY OR (ii) SHALL BE SECURED BY FIRST
MORTGAGE BONDS UNDER A SECURED MORTGAGE INDENTURE OTHER THAN THE MORTGAGE
INDENTURE.

         Reference is made to the further provisions of this Senior Secured
Insured Quarterly Note set forth on the reverse hereof. Such further provisions
shall for all purposes have the same effect as though fully set forth at this
place.

         This Senior Secured Insured Quarterly Note shall not be valid or become
obligatory for any purpose until the certificate of authentication hereon shall
have been manually signed by the Senior Trustee under the Senior Indenture
referred to on the reverse hereof.

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

This Note is one of the series designated as the 6.85% Senior Secured Insured
Quarterly Notes (the "Senior Secured Insured Quarterly Notes") of the Company,
which series is limited in aggregate principal amount to $55,000,000.

             (2) 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

             (c) The Company shall make payment of any principal or interest due

preceding the date on which such payment is due to the Holders of the Senior
Secured Insured Quarter Notes.

             (d) The following defined terms used herein shall, unless the

         (d) Transfer. No service charge will be made for any transfer or
exchange of Senior Secured Insured Quarterly Notes, but payment will be required
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection therewith.

         The Company shall not be required (a) to issue, transfer or exchange
any Senior Secured Insured Quarterly Notes except to the Insurer during a period
beginning at the opening of business fifteen (15) days before the day of the
mailing of a notice pursuant to Section 12.4 of the Indenture identifying the
serial numbers of the Senior Secured Insured Quarterly Notes to be called for
redemption, and ending at the close of business on the day of the mailing, or
(b) to transfer or exchange any Senior Secured Insured Quarterly Notes
theretofore selected for redemption in whole or in part, except the unredeemed
portion of any Note redeemed in part.

         (e) Redemption at the Company's Option. The Senior Secured Insured
Quarterly Notes shall be subject to redemption at the option of the Company, in
whole or in part, without premium or penalty, at any time or from time to time
on or after June 1, 2004 at a Redemption Price equal to 100% of the principal
amount to be redeemed plus accrued but unpaid interest to the Redemption Date.

         In the event of redemption of the Senior Secured Insured Quarterly
Notes in part only, a new Senior Secured Insured Quarterly Note or Notes for the
unredeemed portion will be issued in the name or names of the Holders thereof
upon the surrender thereof.

         The Senior Secured Insured Quarterly Notes will not have a sinking
fund.

         Notice of redemption shall be given as provided in Section 12.4 of the
Indenture.

         Any redemption of less than all of the Senior Secured Insured Quarterly
Notes shall, with respect to the principal thereof, be divisible by $1,000.

         (f) Redemption at the Holder's Option. For purposes of this provision a
"Beneficial Owner" means the Person who has the right to sell, transfer or
otherwise dispose of an interest in Senior Secured Insured Quarterly Notes and
the right to receive the proceeds therefrom, as well as the interest and
principal payable to the Holder thereof. In general, a determination of
beneficial ownership in the Senior Secured Insured Quarterly Notes will be
determined by the Company, in its sole discretion, which determinations shall be
final and binding on all parties.

         Unless the Senior Secured Insured Quarterly Notes have been declared
due and payable prior to their maturity by reason of an Event of Default, the
personal representative or other Person authorized to represent the estate of
the deceased Beneficial Owner or from a surviving joint tenant(s) or tenant(s)
by the entirety (each, a "Representative") of a deceased Beneficial



<PAGE>   14



Owner has the right to request redemption prior to Stated Maturity of all or
part of such interest, expressed in integral multiples of $1,000 principal
amount, in the Senior Secured Insured Quarterly Notes, and the Company will
redeem the same subject to the limitations that the Company will not be
obligated to redeem, during the period from the Original Issue Date through and
including June 1, 2000 (the "Initial Period"), and during any twelve-month
period which ends on and includes each June 1, thereafter (each such
twelve-month period being hereinafter referred to as a "Subsequent Period"), (i)
on behalf of a deceased Beneficial Owner any interest principal amount of
$25,000 or (ii) interests in the Senior Secured Insured Quarterly Notes in an
aggregate principal amount exceeding $1,650,000. A request for redemption may
initiated by the Representative of a deceased Beneficial Owner at any time and
in any principal amount in integral multiples of $1,000. Representatives of
deceased Beneficial Owners must make arrangements with the Participant through
whom such interest is owned in order that timely presentation of redemption
requests can be made by the Participant to the Senior Trustee. If the Company,
although not obligated to do so, chooses to redeem interests of any deceased
Beneficial Owner in the Senior Secured Insured Quarterly Notes in the Initial
Period or any Subsequent Period in excess of the $25,000 limitation, such
redemption, to the extent that it exceeds the $25,000 limitation for any
deceased Beneficial Owner, shall not be included in the computation of the
$1,650,000 limitation for such initial Period or such Subsequent Period, as the
case may be, or for any succeeding Subsequent Period. Any Senior Secured Insured
Note (or portion thereof) tendered pursuant to the redemption request may be
withdrawn by a written request by the Representative received by the Senior
Trustee at least 10 days prior to its repayment.

         Subject to the $25,000 and $1,650,000 limitations, the Company will,
after the death of any Beneficial Owner, redeem the interest of such Beneficial
Owner in the Senior Secured Insured Quarterly Notes within 60 days following
receipt by the Senior Trustee of a redemption request. The Senior Trustee will
notify the Company promptly after receipt of any redemption request and the
Company will provide all funds necessary for such redemption prior to the date
of redemption to the Paying Agent. If redemption requests exceed the aggregate
principal amount of interests in Senior Secured Insured Quarterly Notes required
to be redeemed during the Initial Period or during any Subsequent Period, then
such excess redemption requests will be applied in the order received by the
Senior Trustee to successive Subsequent Periods, regardless of the number of
Subsequent Periods required to redeem such interests. All redemption requests
will be redeemed in the order in which trustee receives the redemption request.
To obtain repayment pursuant to a redemption request, the Representative must
provide to the Participant (i) a written request for repayment signed by the
Representative, and such signature must be guaranteed by a member firm of a
registered national securities exchange or of the NASD or a commercial bank or
trust company having an office or correspondent in the United States, (ii)
appropriate evidence satisfactory to the Company and the Senior Trustee that (A)
the Representative has authority to act on behalf of the deceased Beneficial
Owner, (B) the death of such Beneficial Owner has occurred and (C) the deceased
was the owner of a beneficial interest in such Senior Secured Insured Quarterly
Note at the time of death, (iii) if applicable, a properly executed assigned or
endorsed, and (iv) if the beneficial interest in such Senior Secured Insured
Quarterly Note is held by a nominee of the deceased Beneficial Owner, a
certificate satisfactory to the Senior Trustee from such nominee attesting to
the deceased's ownership of a beneficial interest in such Senior



<PAGE>   15



Secured Insured Quarterly Note. The Participant will provide these documents to
the Senior Trustee. All questions as to the eligibility or validity of any
exercise of redemption on behalf of a deceased Beneficial Owner will be
determined by the Company, in its sole discretion, which determinations will be
final and binding on all parties.

         For purposes of this provision an interest in Senior Secured Insured
Quarterly Notes held in tenancy by the entirety, joint tenancy or by tenants in
common will be deemed to be held by a single Beneficial Owner and the death of a
tenant by the entirety, joint tenant or tenant in common will be deemed the
death of a Beneficial Owner. The death of a Person who, during his lifetime, was
entitled to subsequently all of the rights of a Beneficial Owner of an interest
in the Senior Secured Insured Quarterly Notes will be deemed the death of the
Beneficial Owner, regardless of the recordation of such interest on the records
of the Participant, if such rights can be established to the satisfaction of the
Participant and the Company.

         In the case of any redemption request which is presented pursuant to
this provision and which has not been fulfilled at the time of the Company gives
notice of its election to partially redeem Senior Secured Insured Quarterly
Notes as described in item 3 above, such interest or portion thereof shall not
be subject to redemption pursuant to such item 3 subject to redemption pursuant
to this provision.

         (g)      Special Insurance Provisions.

                  (1) Supplemental Indentures. The consent of the Insurer shall
be required with respect to any indenture or indentures supplemental to the
Indenture requiring the consent of the Holders of the Senior Secured Insured
Quarterly Notes pursuant to Section 10.2 of the Senior Indenture.

                  (2) Events of Default and Remedies. Subject to Section 1.7 of
the Senior Indenture and to the Trust Indenture Act, including, without
limitation, Sections 316(a)(1) and 317(a) thereof, if an Event of Default with
respect to the Senior Secured Insured Quarterly Notes occurs and is continuing,
the Insurer shall be entitled to control and direct the enforcement of all
rights and remedies granted to the Holders of the Senior Secured Insured
Quarterly Notes or the Senior Trustee for the benefit of the Holders of the
Senior Secured Insured Quarterly Notes under the Senior Indenture, including,
without limitation, (i) the right to accelerate the principal of the Senior
Secured Insured Quarterly Notes as provided in Section 6.2 of the Indenture, and
(ii) the right to annul any such declaration of acceleration, and the Insurer
shall also be entitled to approve any waiver of an Event of Default with respect
to the Senior Secured Insured Quarterly Notes, the obligation of the Senior
Trustee to comply with any direction to be subject to compliance with the
conditions set forth in Sections 7.3(e) of the Senior Indenture (as if
references in those Sections to Holders were references to the Insurer) and the
protections provided to the Senior Trustee by Sections 315(d)(3) of the Trust
Indenture Act shall be applicable with respect to any direction from the Insurer
given pursuant thereto (as if references in said Section to Holders were
references to the Insurer).



<PAGE>   16



                  (3) Insurance Policy Payment Procedures. (a) If, as of the
close of business on the second day next preceding any date on which payment of
principal or interest is due, the Senior Trustee does not have sufficient funds
for any payment of principal or interest on the due date or if the Senior
Trustee has notice that any Holder has been required to disgorge payments of
principal or interest on the Senior Secured Insured Quarterly Notes to a trustee
in bankruptcy or creditors or others pursuant to a final judgement by a court of
competent jurisdiction that such payment constitutes an avoidable preference to
such Holder within the meaning of any applicable bankruptcy laws, then the
Senior Trustee shall notify the Insurer or its designee of such fact by
telephone or telegraph notice, confirmed in writing by registered or certified
mail.

                  (b) The Senior Trustee is hereby irrevocably designated,
appointed, directed and authorized to act as attorney-in-fact for Holders of the
Senior Secured Insured Quarterly Notes as follows:

                           (i) If and to the extent there is a deficiency in
                  amounts required to pay interest on the Senior Secured Insured
                  Quarterly Notes, the Senior Trustee shall (x) execute and
                  deliver to the Insurance Paying Agent, in form satisfactory to
                  the Insurance Paying Agent, an instrument appointing the
                  Insurer as agent for such Holders in any legal proceeding
                  related to the payment of such interest and an assignment to

                  (d) Irrespective of whether any such assignment is executed
and delivered, the Company and the Senior Trustee hereby agree for the benefit
of the Insurer that,

                           (i) They recognize that to the extent the Insurer
                  makes payments, directly or indirectly (as by paying through
                  the Senior Trustee), on account of principal of or interest on

                           (ii) They will accordingly pay to the Insurer the
                  amount of such principal and interest (including principal and
                  interest recovered under subparagraph (ii) of the first
                  paragraph of the Policy, which principal and interest shall be
                  deemed past due and not to have been paid), with interest
                  thereon as provided in the Senior Indenture and the Senior
                  Secured Insured Quarterly Note, but only from the sources and

                  and interest on the Senior Secured Insured Quarterly Notes of

                  such rights to the extent of the amount of such principal and
                  interest.

                  (4) Application of Term "Outstanding" to Senior Secured

Senior Indenture confers upon or gives or grants to the Insurer any right,
remedy or claim under or by reason of the Senior Indenture, the Insurer is

long as the Policy shall be in full force and effect and the Insurer is not in
default thereunder.

                  (8) Amendments or Supplements. The Senior Trustee, in
determining whether any amendments or supplements to the Senior Indenture may be
made without the consent of the Holders, or in determining whether any action
should be taken, shall consider the effect of such action on the rights of the

<PAGE>   30



         (c) Payments with respect to claims for interest on and principal of
Senior Notes disbursed by the Senior Trustee from proceeds of the Policy shall
not be considered to discharge the obligation of the Company with respect to
such Senior Notes, and the Insurer shall become the owner of such Senior Notes
and claims for the interest thereon in accordance with the tenor of the
assignment made to it under the provisions of this subsection or otherwise.

         (d) Irrespective of whether any such assignment is executed and
delivered, the Company and the Senior Trustee hereby agree for the benefit of
the Insurer that,

             1. They recognize that to the extent the Insurer makes payments,
         directly or indirectly (as by paying through the Senior Trustee), on
         account of principal of or interest on the Senior Notes, the Insurer
         will be subrogated to the rights of such Holders to receive the amount
         of such principal and interest from the Company, with respect thereon
         as provided and solely from the sources stated in the Senior Indenture
         and the Senior Notes; and

             2. They will accordingly pay to the Insurer the amount of such
         principal and interest (including principal and interest recovered
         under subparagraph (ii) of the first paragraph of the Policy, which
         principal and interest shall be deemed past due and not to have been
         paid), with interest thereon as provided in the Senior Indenture and
         the Senior Note, but only from the sources and in the manner provided
         herein for the payment of principal of and interest on the Senior Notes
         of Holders, and will otherwise treat the Insurer as the owner of such
         rights to the extent of the amount of such principal and interest.

that the principal and/or interest due on the Senior Notes shall be paid by the
Insurer pursuant to the Policy, the Senior Notes shall remain Outstanding for
all purposes of the Senior Indenture, not be considered defeased or otherwise
satisfied and not be considered paid by the Company, and the Senior Indenture
and all covenants, agreements and other obligations of the Company to the
Holders of Senior Notes shall continue to exist and such covenants, agreements
and other obligations shall run to the benefit of the Insurer, and the Insurer
shall be subrogated to the rights of such Holders to the extent of such payment.

         (5) Insurer as Third Party Beneficiary. To the extent that the Senior
Indenture confers upon or gives or grants to the Insurer any right, remedy or
claim under or by reason of the Senior Indenture, the Insurer is hereby
explicitly recognized as being a third-party beneficiary hereunder and may
enforce any such right, remedy or claim conferred, given or granted hereunder.

Senior Note or to the Trustee pursuant to the Senior Indenture shall also be
provided to the Insurer. All notices required to be given to the Insurer under

anything in the Senior Indenture to the contrary, but only so long as the Policy

paid, commencing on the Interest Payment Date next succeeding the Original Issue
Date until the Company's obligation with respect to the payment of such
principal sum shall be discharged provided in the Secured Indenture hereinafter
mentioned and the Senior Indenture. If the date of the Collateral Bonds
presented by this certificate is after a Record Date (as defined below) with
respect to any Interest Payment Date and prior to the Interest Payment Date,
then payment of interest shall commence on the second Interest Payment Date
succeeding the date. If the Company shall default in the payment of interest due
on any Interest Payment Date, then interest shall be payable from the next
preceding Interest Payment Date to which interest has been paid, or, if no such
interest has been paid on the Collateral Bonds represented by this certificate,
from the Original Issue Date. So long as there is no existing default in the
payment of interest, the person in whose name the Collateral Bonds represented
by this certificate were registered at the close of business 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 Interest Payment
Date, such defaulted interest shall be paid to the person in whose name the

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.

         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



<PAGE>   39

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") 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 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, purchase 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 (as defined in the Senior Indenture), have been retired (at, before or
after the maturity hereof) 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.



<PAGE>   40

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 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, 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, state 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.
