Ladies and Gentlemen:

                 MCN Investment Corporation (the "Company"), a Michigan
corporation and a wholly-owned subsidiary of MCN Corporation, a Michigan
corporation ("MCN"), confirms its agreement with each of you (individually, an
"Agent" and collectively, the "Agents") with respect to the issue and sale by
the Company of up to an aggregate principal amount of $500,000,000 of its
Medium-Term Notes, Series B, Due Nine Months or More from Date of Issue (the
"Notes").  The Notes will be issued from time to time by the Company under an
Indenture dated as of September 1, 1995 (the "Indenture") between the Company
and NBD Bank, as trustee.  The Notes will mature nine months or more from the
date of issue and
<PAGE>   2

will bear interest at rates to be specified in a pricing supplement to the Note
Prospectus referred to below.  It is understood, however, that the Company may
from time to time authorize the issuance of additional Notes and that such
additional Notes may be sold to or through the Agents pursuant to the terms of
this Agreement, as though the issuance of such Notes were authorized as of the
date hereof.  The Notes will have the benefit of a Support Agreement dated as
of September 1, 1995 (the "Support Agreement") between the Company and MCN.

                 1.  Solicitations as Agents; Purchases as Principal.

                 (a)  Appointment.  Subject to the terms and conditions stated
herein, the Company hereby agrees that the Notes will be sold to or through the
Agents; provided, however, that the Company reserves the right to sell and may
accept offers to purchase the Notes directly on its own behalf.  In addition,
the Company may from time to time offer Notes for sale otherwise than through
an Agent; provided, however, that so long as this Agreement shall be in effect
the Company shall not solicit offers to purchase Notes through any agent
without amending this Agreement to appoint such agent as an additional Agent
hereunder on the same terms and conditions as provided herein for the Agents
and without giving the Agents prior notice of such appointment.  The Company
may accept offers to purchase Notes through an agent other than an Agent,
provided that (i) the Company shall not have solicited such offers, (ii) the
Company and such agent shall have executed an agreement with respect to such
purchases having terms and conditions (including, without limitation,
commission rates) with respect to such purchases substantially the same as the
terms and conditions that would apply to such purchases under this Agreement if
such agent was an Agent (which may be accomplished by incorporating by
reference in such agreement the terms and conditions of this Agreement) and
(iii) the Company shall provide the Agents with a copy of such agreement
promptly following the execution thereof.  On the basis of the representations
and warranties herein contained, but subject to the terms and conditions herein
set forth, each Agent agrees, as an agent of the Company, to use its reasonable
efforts to solicit offers to purchase the Notes during each Offering Period
(defined below) upon the terms and conditions set forth in the Note Prospectus
(defined below) as then amended and supplemented.  Each Agent may also purchase
Notes from the Company as principal for purposes of resale, as more fully
described in subsection (g) of this Section.

                 (b)  Solicitation Period.  Following the Commencement Date
(defined below), the Company shall notify each Agent from time to time as to
the commencement of a period during which the Notes may be offered and sold by
such Agent (each period, commencing with such a notification and ending at such
time as the authorization for offers and sales through such Agent shall





                                     -2-
<PAGE>   3

have been suspended by the Company or such Agent as provided hereunder, being
herein referred to as an "Offering Period").

                 (c)  Agent's Commission.  The Company agrees to pay each
Agent, as consideration for soliciting the sale of the Notes, a commission in
the form of a discount, equal to the percentage of the principal amount of each
Note sold by the Company as a result of a solicitation made by an Agent as set
forth on Schedule I hereto.

                 (d)  Solicitation of Offers.  Each Agent is authorized to
solicit orders for the Notes only in denominations of $1,000 or any larger
amount that is an integral multiple of $1,000, at a purchase price equal to
100% of their principal amount (unless otherwise specified in the applicable
pricing supplement).  Each Agent shall communicate to the Company, orally, each
reasonable offer or indication of interest received by it to purchase Notes.
The Company shall have the sole right to accept offers to purchase the Notes
and may reject any such offer in whole or in part.  Each Agent shall have the
right to reject, in its discretion reasonably exercised, any offer received by
it to purchase the Notes, without advising the Company, in whole or in part,
and any such rejection shall not be deemed a breach of its agreements contained
herein.  In soliciting offers to purchase the Notes hereunder, each Agent is
acting solely as agent for the Company, and not as principal.  Each Agent shall
make reasonable efforts to assist the Company in obtaining performance by each
purchaser whose offer to purchase Notes has been solicited by such Agent and
accepted by the Company, but such Agent shall not have any liability to the
Company in the event any such purchase is not consummated for any reason.
Under no circumstances will an Agent be obligated to purchase any Notes for its
own account.  If the Company shall default in its obligations to deliver Notes
to a purchaser whose offer it has accepted, the Company shall (a) hold the
Agents harmless against any loss, claim or damage arising from or as a result
of such default by the Company and (b) notwithstanding such default, pay to the
Agents any commission to which they would be entitled in connection with such
sale.

                 (e)  Administrative Procedures.  The purchase price, interest
rate or formula, maturity date and other terms of the Notes (as applicable)
shall be agreed upon by the Company and the Agent and set forth in a pricing
supplement to be prepared in connection with each sale of the Notes.  Each
Agent and the Company agree to perform the respective duties and obligations
specifically provided to be performed by it in the Administrative Procedures
attached hereto as Exhibit A (the "Procedures").  The Procedures may be amended
only by written agreement from time to time of the Company and the Agents.

                 (f)  Delivery of Documents.  The documents required to be
delivered by Section 4 of this Agreement shall be delivered at





                                      -3-

  
<PAGE>   4

the offices of LeBoeuf, Lamb, Greene & MacRae, L.L.P., counsel for the Agents,
125 West 55th Street, New York, N.Y. 10019-5389, on such date as may be
mutually agreed to by the Company and the Agents, which in no event shall be
later than the time at which the Agents commence solicitation of offers to
purchase Notes hereunder (the "Commencement Date").

                 (g)  Purchases as Principal.  Subject to the terms and
conditions stated herein, the Company agrees that, whenever the Company
determines to sell Notes directly to any of the Agents as principal for resale
to others and such Agent agrees to purchase Notes as principal, it will enter
into a Terms Agreement (defined below) relating to such sale in accordance with
the provisions of this Section 1(g).  Each sale of Notes to any of the Agents
as principal shall be made in accordance with the terms of this Agreement and a
supplemental agreement which will provide for the sale of such Notes to, and
the purchase and reoffering thereof by, such Agent.  Each such supplemental
agreement, whether oral (and confirmed in writing by such Agent to the Company,
which may be by facsimile transmission) or in writing is herein referred to as
a "Terms Agreement".  Each such Terms Agreement, whether oral or in writing,
shall be with respect to such information (as applicable) as is specified in
Exhibit B hereto.  Each Agent's commitment to purchase Notes pursuant to any
Terms Agreement shall be deemed to have been made on the basis of the
representations and warranties of the Company herein contained and shall be
subject to the terms and conditions herein set forth.  Each Terms Agreement
shall describe the Notes to be purchased by any of the Agents pursuant thereto,
specify the principal amount of such Notes, the price to be paid to the Company
for such Notes, the rate at which interest will be paid on the Notes, the date,
time and place of delivery of the Notes and payment therefor (the "Purchase
Date"), the method of payment and any modification of the requirements for the
delivery of the opinions of counsel, the certificates from the Company, and the
comfort letter from Deloitte & Touche LLP, pursuant to Section 4.  Such Terms
Agreement shall also specify the period of time referred to in Section 3(k).

                 Delivery of the certificates for Notes sold to any of the
Agents pursuant to any Terms Agreement shall be made as agreed to between the
Company and such Agent as set forth in the Terms Agreement, no later than the
Purchase Date set forth in such Terms Agreement, against payment of funds to
the Company in the net amount due to the Company for such Notes by the method
and in the form set forth in the Terms Agreement.

                 Unless otherwise indicated in the applicable pricing
supplement, any Note sold to an Agent as principal shall be at a discount from
the principal amount of each such Note equivalent to the applicable commission
set forth in Schedule I hereto, and may be resold by such Agent to investors
and other purchasers from time to time in one or more transactions at varying
prices





                                      -4-

  
<PAGE>   5

determined at the time of sale, or at a fixed public offering price, if so
agreed.  In addition, such Agent may engage the services of any other broker or
dealer in connection with the resale of the Notes purchased by it as principal
and may allow any portion of the discount received in connection with such
purchases from the Company to such brokers or dealers.

                 (h)  Other Activities of Agents.  The Company acknowledges
that nothing in this Agreement shall prohibit any Agent from (i) acting as
broker for the sale of Notes by customers other than the Company, (ii)
soliciting the sale of Notes through the Agent as broker for the seller,
soliciting the sale of Notes to the Agent as principal and soliciting offers to
buy Notes, (iii) purchasing Notes, and (iv) offering and selling as principal
for its own account Notes which the Agent has purchased.

                 (i)  Reliance.  The Company and each Agent agree that any
Notes purchased by the Agents shall be purchased, and any Notes the placement
of which an Agent arranges shall be placed by such Agent, in reliance on the
representations, warranties, covenants and agreements of the Company contained
herein and on the terms and conditions and in the manner provided herein.

                 2.  Representations and Warranties of the Company and MCN.
Each of the Company and MCN jointly and severally represents and warrants to,
and agrees with, each of the Agents that:

                 (a)  Each of the Company and MCN meets the requirements for
use of Form S-3 under the Securities Act of 1933, as amended (the "Act") and
have filed with the Securities and Exchange Commission (the "Commission"), as
co-registrants, a registration statement on such form (File No. 333-01523) for
the registration under the Act of the Company's debt securities, including the
Notes, and the obligations pursuant to the Support Agreement which registration
statement was declared effective on March 27, 1996.  The Company may from time
to time file with the Commission additional registration statements for the
registration of additional amounts of debt securities.  At the time of the
offer and sale of any Note pursuant to this Agreement, such Note shall be
registered pursuant to an effective registration statement under the Act.  Each
registration statement under which Notes are offered or sold pursuant to this
Agreement at the date hereof and at the date of such offer and sale meets and
will meet the requirements set forth in Rule 415(a)(1)(x) under the Act and
complies and will comply in all other material respects with said Rule.
"Registration Statement" shall mean, as of any date, each effective
registration statement relating to debt securities pursuant to which Notes are
or may then be offered or sold, including incorporated documents, exhibits and
financial statements, as amended at such date.  "Prospectus" shall mean the
form of prospectus relating to debt securities contained in the





                                      -5-

  
<PAGE>   6

Registration Statement.  The term "Preliminary Prospectus" as used herein means
a prospectus filed as part of any post-effective amendment to the Registration
Statement prior to the effective date of such post-effective amendment, as
contemplated in Rule 430 under the Act.  The Company has included and will
include in each such Registration Statement, or has filed or will file with the
Commission pursuant to the applicable paragraph of Rule 424(b) under the Act, a
supplement to the form of Prospectus included in each such Registration
Statement relating to the Notes and prior to any such filing will advise each
Agent of all further information (financial and other) with respect to the
Company to be set forth therein.  The Prospectus so supplemented from time to
time is hereinafter called the "Note Prospectus".  Any reference herein to the
Registration Statement, any Preliminary Prospectus, the Prospectus, or the Note
Prospectus, as amended and supplemented, shall be deemed to refer to and
include the documents incorporated by reference therein pursuant to Item 12 of
Form S-3 that were filed under the Securities Exchange Act of 1934, as amended
(the "Exchange Act") on or before the effective date of the Registration
Statement, or the issue date of such Preliminary Prospectus, the Prospectus, or
the Note Prospectus, as the case may be; and any reference herein to the terms
"amend", "amendment" or "supplement" with respect to the Registration
Statement, any Preliminary Prospectus, the Prospectus, or the Note Prospectus
shall be deemed to refer to and include (i) the filing of any document under
the Exchange Act after the effective date of the Registration Statement or the
issue date of any Preliminary Prospectus, the Prospectus, or the Note
Prospectus, as the case may be, deemed to be incorporated therein by reference
and (ii) with respect to the Registration Statement, the filing of any
additional registration statement relating to debt securities if Notes are to
be offered or sold under such additional registration statement.

                 (b)  When the Registration Statement became effective, when
any amendment to the Registration Statement becomes effective (including the
filing of any document incorporated by reference in the Registration
Statement), when any supplement to the Prospectus (other than a supplement
specifying the terms of the debt securities other than the Notes) or the Note
Prospectus is filed with the Commission pursuant to Rule 424(b) under the Act,
on each day during an Offering Period, and at the time of each delivery of
Notes to (i) any purchaser or his Agent whose offer to purchase such Notes was
delivered to the Company during an Offering Period and (ii) any Agent
purchasing such Notes as principal pursuant to a Terms Agreement (each such
time referenced above being referred to herein as a "Representation Date"):

                   (i)    No stop order suspending the effectiveness of the
         Registration Statement is in effect, and no proceeding for such
         purpose has been initiated or, to the knowledge of the Company or MCN,
         threatened by the Commission;





                                      -6-

  
<PAGE>   7


                  (ii)    The Company and MCN meet the requirements for the use
         of Form S-3 under the Act.  The Registration Statement and the Note
         Prospectus comply, and any amendments or supplements thereto will
         comply, in all material respects to the requirements of the Act and
         the Trust Indenture Act of 1939, as amended (the "Trust Indenture
         Act"), and the rules and regulations of the Commission thereunder and
         do not and will not, as of the applicable effective date in the case
         of the Registration Statement and any amendment thereto and as of the
         applicable filing date in the case of the Note Prospectus and any
         supplement thereto, contain an untrue statement of a material fact or
         omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading; provided,
         however, that this representation and warranty shall not apply to any
         statements or omissions made in reliance upon and in conformity with
         information furnished in writing to the Company or MCN by the Agents
         expressly for use in the Registration Statement or Note Prospectus as
         amended or supplemented to relate to a particular issuance of the
         Notes;

                 (iii)    The documents incorporated or deemed to be
         incorporated by reference in the Registration Statement or the Note
         Prospectus, or any amendment or supplement thereto, at the time they
         were or hereafter are filed with the Commission or last amended, as
         the case may be, complied and will comply in all material respects
         with the requirements of the Act or the Exchange Act, as applicable,
         and the rules and regulations of the Commission thereunder, and none
         of such documents contained or will contain an untrue statement of a
         material fact or omitted or will omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading; provided, however, that this
         representation and warranty shall not apply to any statements or
         omissions made in reliance upon and in conformity with information
         furnished in writing to the Company or MCN by the Agents expressly for
         use in the Note Prospectus as amended or supplemented to relate to a
         particular issuance of the Notes;

                  (iv)    The financial statements included or incorporated by
         reference in the Registration Statement and the Note Prospectus,
         together with the related schedules and notes, present fairly the
         financial position of MCN and its consolidated subsidiaries as of the
         dates indicated and the results of their operations for the periods
         specified.  Except as otherwise stated in the Registration Statement,
         said financial statements have been prepared in conformity with
         generally accepted accounting principles applied on a consistent
         basis.  The supporting schedules included or incorporated by reference
         in the Registration Statement present fairly the information required
         to be stated therein.  The ratio of earnings to fixed charges included
         in





                                      -7-

         the Note Prospectus has been calculated in compliance with Item 503(d)
         of Regulation S-K of the Commission.  The selected financial
         information and the summary financial data included in the Note
         Prospectus present fairly the information shown therein and have been
         compiled on a basis consistent with that of the audited financial
         statements included in the Registration Statement;

                   (v)    Neither the Company, MCN nor any of their respective
         subsidiaries has sustained since the date of the latest audited
         financial statements included or incorporated by reference in the Note
         Prospectus any material loss or any material adverse change and no
         development which could reasonably be expected to result in a material
         adverse change in the condition, financial or otherwise, or in the
         earnings, business affairs or business prospects of the Company or MCN
         and their respective subsidiaries considered as one enterprise,
         otherwise than as set forth in the Note Prospectus; and, since the
         respective dates as of which information is given in the Registration
         Statement and the Note Prospectus, except as otherwise stated therein,
         (A) there has not been any change in the capital stock or long-term
         debt including capital lease obligations (other than changes resulting
         from sinking fund and installment provisions under any long-term debt
         agreement (scheduled payments on lease obligations) to which the
         Company, MCN or any of their respective subsidiaries is a party, the
         terms of the preferred redeemable increased dividend equity securities
         of MCN, terms of the preferred securities of MCN Michigan Limited
         Partnership ("MCN Michigan") and purchases in the open market in
         anticipation thereof or any other changes which changes are not, in
         the aggregate, material) of the Company or any of its subsidiaries,
         (B) there have been no transactions entered into by the Company, MCN
         or any of their respective subsidiaries, other than those in the
         ordinary course of business, which are material with respect to the
         Company or MCN and their respective subsidiaries considered as one
         enterprise, (C) 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 or MCN and their
         respective subsidiaries considered as one enterprise, (D) except for
         regular quarterly dividends on common stock of MCN in amounts per
         share that are consistent with past practice and except for the yield
         enhancement payments on the 8-3/4% Preferred Redeemable Increased
         Dividend Equity Securities of MCN in amounts consistent with the terms

                 3.  Covenants of the Company and MCN.  Each of the Company and
MCN agrees with each Agent that:

                 (a)  The Company or MCN will give each Agent advance notice of
its intention to file or prepare any additional registration statement with
respect to the registration of additional Notes, any amendment to the
Registration Statement, any amendment or supplement to the Prospectus which
would create a Note Prospectus, or any amendment or supplement to the Note
Prospectus (other than an amendment or supplement providing solely for a change
in the interest rate of the Notes and other than a pricing supplement except
with respect to the Agent which made or presented the offer to purchase the
applicable Note), whether by filing of documents pursuant to the Act, the
Exchange Act or otherwise, and will furnish each Agent with copies thereof for
its review a reasonable time in advance of such proposed filing or preparation,
as the case may be, and will not file any such proposed amendment or supplement
or other documents in a form to which any Agent or counsel for the Agents shall
reasonably object.  Subject to the foregoing sentence, the Company and MCN will
promptly cause the Prospectus together with each supplement thereto which would
create a Note Prospectus, and each Note Prospectus together with each
supplement thereto, to be filed with the Commission pursuant to Rule 424(b)
under the Act.

                 (b)  The Company and MCN will promptly advise the Agents (i)
when any amendment to the Registration Statement shall have become effective,
(ii) of the filing of any amendment or supplement to the Prospectus which
creates a Note Prospectus, including the filing of documents incorporated
therein by reference, (iii) of the filing of any amendment or supplement to the
Note Prospectus, including the filing of documents incorporated therein by
reference, (iv) of any request by the Commission for any amendment of the
Registration Statement or amendment or supplement to the Prospectus which would
create a Note Prospectus, or any amendment of or supplement to the Note
Prospectus, or for any additional information or any comments with respect
thereto, (v) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or the institution or threatening
of any proceeding for such purpose and (vi) of the receipt by the Company or
MCN of any notification with respect to the suspension of the qualification of
the Notes for sale in any state or jurisdiction or the initiation or
threatening of any proceeding for such purpose.  The Company and MCN will use
their best efforts to prevent the issuance of any such stop order and, if
issued, to obtain as soon as possible the withdrawal thereof.  The Company will
inform you promptly, upon your request, of the aggregate offering price or





                                      -14-

  
<PAGE>   15

purchase price of debt securities registered under the Registration Statement
that remain unissued, and will promptly advise you to suspend solicitations of
orders to purchase Notes at any time when all securities registered under the
Registration Statement have been issued.

                 (c)  If, at any time when a prospectus relating to the Notes
is required to be delivered under the Act, any event occurs as a result of
which the Registration Statement or the Note Prospectus as then amended or
supplemented would include an untrue statement of a material fact or omit to
state a material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, or if it shall be
necessary to amend or supplement the Registration Statement or the Note
Prospectus to comply with the Act or the Exchange Act or the rules and
regulations of the Commission thereunder, the Company or MCN will immediately
notify each Agent, such notice to be confirmed in writing, and, if so notified
by the Company or MCN, each Agent shall forthwith suspend solicitation of
offers to purchase Notes in the Agents' capacities as agent and cease sales of
any Notes any Agent may then own as principal; the Company and MCN promptly
will prepare and file with the Commission, subject to subsections (a) and (b)
of this Section 3, an amendment or supplement to the Registration Statement or
Note Prospectus which will correct such statement or omission or an amendment
which will effect such compliance and will supply such amended or supplemented
Note Prospectus to each Agent in such quantities as such Agent may reasonably
request.  If such amendment or supplement, and any documents, certificates and
opinions furnished to each Agent pursuant to Section 3(i) below in connection
with the preparation or filing of such amendment or supplement, are
satisfactory in all respects to each Agent, each Agent will, upon the filing of
such amendment or supplement with the Commission or effectiveness of an
amendment to the Registration Statement, resume its obligations to solicit
offers to purchase Notes hereunder.

                 (d)  MCN will make generally available to its security holders
and deliver to each of the Agents as soon as practicable, but not later than 15
months after the end of a fiscal quarter of MCN during which any Notes are sold
through or purchased by any of the Agents, a consolidated earnings statement
(which need not be audited) of MCN and its subsidiaries for the 12-month period
within such 15 months, which earnings statements shall satisfy the provisions
of Section 11(a) of the Act and the rules and regulations of the Commission
thereunder (including Rule 158 under the Act).

                 (e)  The Company and MCN will deliver to (i) each Agent and
counsel for the Agents as many signed and conformed 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





                                      -15-

  
<PAGE>   16

deemed to be incorporated by reference therein) as the Agents may reasonably
request and (ii) as many copies of the Note Prospectus (as amended or
supplemented) as the Agents may reasonably request so long as the Agents are
required to deliver a Note Prospectus in connection with sales or solicitations
of offers to purchase the Notes.

                 (f)  The Company and MCN will prepare, with respect to any
Notes to be sold through or to the Agent pursuant to this Agreement, a pricing
supplement with respect to such Notes in a form previously approved by the
Agent and will file such pricing supplement pursuant to Rule 424(b) under the
Act not later than the close of business of the Commission on the fifth
business day after the date on which such pricing supplement is first used or
such earlier time as such pricing supplement may be required to be filed with
the Commission.

                 (g)  The Company and MCN will use their best efforts to
arrange for the qualification of the Notes for sale under the laws of such
jurisdictions as the Agents may designate (provided, however, that neither the
Company nor MCN shall be obligated to qualify as a foreign corporation in, or
to execute or file any general consent to service of process under the laws of
any jurisdiction), will maintain such qualifications in effect so long as
required for the distribution of the Notes and will arrange for the
determination of the legality of the Notes for purchase by institutional
investors.

                 (h)  In the event that the Company exercises its right to sell
Notes directly on its own behalf, such sales shall be made in compliance with
Federal and state securities laws, including those relating to broker-dealer
and salesperson registration.

                 (i)  The Company and MCN shall furnish to each Agent such
documents, certificates of officers of the Company or MCN, and opinions of
counsel for the Company or MCN, relating to the business, operations and
affairs of the Company or MCN, the Registration Statement and the Note
Prospectus, any amendments or supplements thereto, the Indenture, the Notes,
this Agreement, the Support Agreement, the Procedures and the performance by
the Company, MCN and the Agents of their respective obligations hereunder and
thereunder as any of the Agents may from time to time prior to the termination
of this Agreement reasonably request.

                 (j)  The Company and MCN, during the period when the Note
Prospectus is required to be delivered under the Act, will file all documents
required to be filed with the Commission pursuant to Section 13, 14 or 15 of
the Exchange Act within the time periods required by the Exchange Act and the
rules and regulations of the Commission thereunder.

                 (k)  During the period, if any, specified in the Terms
Agreement, the Company will not offer, sell, contract to sell or otherwise
dispose of any debt securities of the Company, other than the Notes, without
the prior written consent of the Agents.

                 (l)  On or prior to the date on which there shall be released
to the general public interim financial statement information related to MCN
with respect to each of the first three quarters of any fiscal year or
preliminary financial statement information with respect to any fiscal year,
the Company and MCN shall furnish such information to the Agents, confirmed in
writing, and shall cause the Note Prospectus to be amended or supplemented to
include or incorporate by reference financial information with respect thereto
and corresponding information for the comparable period of the preceding fiscal
year, as well as such other information and explanations as shall be necessary
for an understanding thereof or as shall be required by the Act or the Exchange
Act and the rules and regulations of the Commission thereunder.

                 (m)  On or prior to the date on which there shall be released
to the general public financial information included in or derived from the
audited financial statements of MCN for the preceding fiscal year, the Company
and MCN shall cause the Registration Statement and the Note Prospectus to be
amended, whether by the filing of documents pursuant to the Exchange Act, the
Act or otherwise, to include or incorporate by reference such audited financial
statements and the report or reports, and consent or consents to such inclusion
or incorporation by reference, of the independent accountants with respect
thereto, as well as such other information and explanations as shall be
necessary for an understanding of such financial statements or as shall be

                 (b)  Each Agent shall have received the opinion of Daniel L.
Schiffer, Esq., Senior Vice President, General Counsel and Secretary for MCN,
and Vice President, General Counsel and Secretary of the Company, dated the
Commencement Date, in form and substance satisfactory to the Agents and their
counsel, to the effect that:

                 (i)  each of the Company and MCN has been duly incorporated
         and is validly existing as a corporation in good standing under the
         laws of the State of Michigan, with corporate power and authority to
         own, lease and operate its properties and conduct its business as
         described in the Registration Statement and the Note Prospectus and to
         execute and deliver this Agreement and to perform its obligations
         hereunder; and neither the Company nor MCN owns or leases property or
         conducts any business so as to require qualification as a foreign
         corporation for the transaction of business in any jurisdiction where
         it is not qualified to transact business, except where the failure to
         so qualify would not have a material adverse effect on the condition,
         financial or otherwise, or on the earnings, business affairs or
         business prospects of the Company or MCN and their respective
         subsidiaries considered as one enterprise;

             (ii)  Each subsidiary of the Company and MCN has been duly

         power and authority to own, lease and operate its properties and to
         conduct its business as presently conducted and as described in the
         Registration Statement and the Note Prospectus and is duly qualified
         as a foreign corporation to transact business and is in good standing
         in each jurisdiction in which such qualification is required, whether
         by reason of the ownership or leasing of property or the conduct of
         business, except where the failure to so qualify or be in good
         standing would not have a material adverse effect on the condition,
         financial or otherwise, or on the earnings, business affairs or
         business prospects of the Company or MCN and their respective
         subsidiaries considered as one enterprise; all of the issued and
         outstanding shares of capital stock of each such subsidiary has been
         duly authorized and validly issued, are fully paid and non- assessable
         and, to the best of such counsel's knowledge all such shares are owned

         subsidiaries, free and clear of any security interest, mortgage,
         pledge, lien, encumbrance, claim or equity;

            (iii)  None of the Company, MCN nor any of their respective
         subsidiaries is in violation of its charter or in





                                      -18-

         agreement, covenant or condition contained in any contract, indenture,
         mortgage, loan agreement, note, lease or other instrument to which it
         is a party or by which it or any of them or their properties may be
         bound; the issue and sale of the Notes, the compliance by the Company
         with all of the provisions of the Notes, the execution, delivery and
         performance by the Company and MCN of this Agreement, the execution,

         execution, delivery and performance by the Company and MCN of the
         Support Agreement, the consummation of the transactions herein and
         therein contemplated, and the compliance by the Company and MCN with
         their obligations hereunder and thereunder have been duly authorized
         by all necessary corporate action of the Company and MCN and will not
         conflict with or result in a breach or violation of any of the terms
         or provisions of, or constitute a default under, or result in the
         creation or imposition of any lien, charge or encumbrance upon any of
         the property or assets of the Company or MCN or any of their
         respective subsidiaries pursuant to the terms of, any statute,
         indenture, mortgage, deed of trust, loan agreement, note, lease or
         other agreement or instrument to which the Company or MCN or any of
         their respective subsidiaries is a party or by which the Company or
         MCN or any of their respective subsidiaries is bound or to which any
         of the property or assets of the Company or MCN or any of their
         respective subsidiaries is subject, nor will such action result in any
         violation of the provisions of the charter or by-laws of the Company
         or MCN, the charter or by-laws of any of their respective
         subsidiaries, or any order, rule or regulation known to such counsel
         of any court or governmental agency or body having jurisdiction over
         the Company or MCN or any of their respective subsidiaries or any of
         its or their properties; and all consents, approvals, authorizations,
         orders, registrations or qualifications of or with any court or any
         such regulatory authority or other governmental body required for the
         solicitation of offers to purchase the Notes, the issue and sale of
         the Notes or the consummation of the other transactions contemplated
         by this Agreement, the Support Agreement or the Indenture, including
         the registration under the Act of the Notes and the qualification of
         the Indenture under the Trust Indenture Act have been obtained and are
         in full force and effect, except such consents, approvals,

         than those described or referred to therein or filed or incorporated
         by reference as exhibits thereto; the descriptions thereof or
         references thereto are correct, and no default exists in the due
         performance or observance of any material obligation, agreement,
         covenant or condition contained in any contract, indenture, mortgage,

         condition, financial or otherwise, or the earnings, business affairs
         or business prospects of the Company or MCN and their respective
         subsidiaries considered as one enterprise; all such licenses,
         franchises, indeterminate permits, certificates, other permits,

         affecting the Company or MCN or any of their respective subsidiaries,
         which is required to be disclosed in the Registration Statement or the

         properties or assets thereof or which might materially and adversely
         affect the consummation of any transaction contemplated by this
         Agreement; all pending legal or governmental proceedings to which the
         Company or MCN or any of their respective subsidiaries is a party or
         to which any of their respective property or assets is the subject
         which are not

         including ordinary routine litigation incidental to the business of
         the Company or MCN or any of their respective subsidiaries, are,
         considered in the aggregate, not material; and there are no contracts

         therein, by the Act or the Exchange Act, as applicable, and the rules
         and regulations of the Commission thereunder, which have not been so
         filed;

            (vii)  Each of the Company and MCN has an authorized capitalization
         as set forth in the Note Prospectus and all of the issued and
         outstanding shares of capital stock of the Company and MCN have been
         duly and validly authorized and issued and are fully paid and
         nonassessable;

           (viii)  Each of the Company, MCN and their respective subsidiaries
         has good and marketable title to all material real and personal
         property owned by each of them, in each case free and clear of all
         liens, encumbrances and defects except such as are described in the
         Registration Statement or Note Prospectus or such as do not materially
         affect the value of such property and do not materially interfere with
         the use made or proposed to be made of such property by the Company,
         MCN or their respective subsidiaries, respectively; and any real
         property and buildings held under lease by the Company, MCN and their

         enforceable leases with such exceptions as are not material and do not
         interfere with the use made and proposed to be made of such property
         and buildings by the Company, MCN or their respective subsidiaries,
         respectively;

         summaries of legal matters, documents or proceedings, or legal
         conclusions, has been reviewed by such counsel and is correct in all
         material respects; such counsel has no reason to believe that, as of
         the effective date of the Registration Statement, either the
         Registration Statement or the Note Prospectus (or, as of its date, any
         amendment or supplement thereto made by the Company or MCN prior to
         the date of such opinion) 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, as
         of the date of such opinion, either the Registration Statement or the
         Note Prospectus (or any such amendment or supplement thereto) contains
         an untrue statement of a material fact or





                                      -21-

  
<PAGE>   22

         omits to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading;

              (x)  The Registration Statement is effective under the Act and
         no stop order suspending the effectiveness of the Registration
         Statement has been issued under the Act or, proceedings therefor
         instituted or, to the best of such counsel's knowledge, threatened by
         the Commission; the Registration Statement and the Note Prospectus and
         any further amendments and supplements thereto prior to the date of
         such opinion (other than financial statements and related schedules
         and other financial or statistical data included or incorporated by
         reference therein, as to which such counsel need express no opinion),
         comply as to form in all material respects with the requirements of
         the Act and the Trust Indenture Act and the rules and regulations of
         the Commission thereunder;

             (xi)  The documents incorporated or deemed to be incorporated by
         reference in the Registration Statement or Note Prospectus, or any
         amendment or supplement thereto, at the time they were filed with the
         Commission or amended (other than the financial statements and related
         schedules and other financial or statistical data included or
         incorporated by reference therein, as to which such counsel need
         express no opinion), complied as to form in all material respects with
         the requirements of the Act and the Exchange Act, as applicable, and
         the rules and regulations of the Commission thereunder; and such
         counsel has no reason to believe that any of such documents, when such
         documents became effective or were so filed, as the case may be,
         contained, in the case of the Registration Statement, an untrue
         statement of a material fact, or omitted to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, and, in the case of other documents which were
         filed under the Exchange Act with the Commission, an untrue statement
         of a material fact or omitted to state a material fact necessary in
         order to make the statements therein not misleading;

           (xii)  The Indenture has been duly and validly authorized, executed
         and delivered by the Company and qualified under the Trust Indenture
         Act and constitutes a valid and legally binding instrument,
         enforceable in accordance with its terms, except as the enforcement
         thereof may be limited by bankruptcy, insolvency, reorganization or
         other similar laws of general applicability relating to or affecting
         creditors' rights or by general equity principles;

            (xiii)  All taxes and fees required to be paid by the laws of the
         State of Michigan and jurisdictional subdivisions thereof with respect
         to the execution of the Indenture and the issuance of the Notes have

         offer and sale pursuant to this Agreement, and when issued,
         authenticated and delivered pursuant to the provisions of this
         Agreement and the Indenture against payment of the consideration
         therefor, will constitute valid and legally binding obligations of the
         Company, enforceable in accordance with their terms, except as the
         enforcement thereof may be limited by bankruptcy, insolvency,
         reorganization, moratorium or other similar laws of general
         applicability relating to or affecting creditors' rights or by general
         equity principles, and each holder of Notes will be entitled to the
         benefits provided by the Support Agreement and the Indenture; and the

         descriptions thereof in the Note Prospectus;

         duly and validly authorized, executed and delivered by each of the
         Company and MCN;

         date hereof, when issued, authenticated and delivered pursuant to the

         exempted from the provisions of the Commodity Exchange Act, assuming
         the accuracy of any certifications of factual matters furnished by the
         Agents or the Company in connection with the issuance thereof;

          (xvii)  MCN is presently exempt from the provisions of the 1935 Act
         (except Section 9(a)(2) thereof) which would otherwise require it to
         register thereunder;

            (xviii)       None of the Company, MCN or any of their  respective
         subsidiaries is an "investment company" or under the "control" of an
         "investment company" as such terms are defined under the 1940 Act; and

             (xix)  The Company and MCN are in compliance with all provisions
         of Section 1 of the Laws of Florida, Chapter 92-198, An Act Relating

(c), respectively, of this Section, Daniel L. Schiffer, Esq. and LeBoeuf, Lamb,
Greene & MacRae, L.L.P. shall each additionally state that nothing has come to
their attention that would lead them to believe that the Registration Statement
(other than the financial statements and related schedules and other financial
or statistical data included or incorporated by reference therein, as to which
counsel need express no opinion), at the time it became effective or at the
Commencement Date, contained an untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading or that the Note Prospectus (other than the
financial statements and related schedules and other financial or statistical

express no opinion), at the Commencement Date, or if such opinion is being
delivered in connection with the purchase of Notes by the Agent as principal
pursuant to Section 1(g) hereof at the date of any Terms Agreement and at the
Purchase Date with respect thereto, as the case may be, included (or includes)
an untrue statement of a material fact or omitted or omits to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.  In giving their
opinion, LeBoeuf, Lamb, Greene & MacRae, L.L.P. may rely as to matters of
Michigan law upon the opinion of Daniel L. Schiffer, Esq. which opinion shall

since the respective dates as of which information is given in the Registration
Statement and the Note Prospectus, as amended and supplemented, or since the
date of any agreement by any Agent to purchase Notes as principal, any material
adverse change in the condition, financial or otherwise, or in the earnings,
business affairs or business prospects of the Company or MCN and their

                 (f)  At the Commencement Date, each Agent shall have received
from Deloitte & Touche LLP a letter dated the Commencement Date in form and
substance satisfactory to each Agent, to the effect set forth below and as to
such other matters as the Agents may reasonably request, that:

                 (i)  They are independent certified public accountants with
         respect to MCN and its respective subsidiaries within the meaning of
         the Act and the applicable published rules and regulations thereunder;

             (ii)  In their opinion, the consolidated financial statements and
         any supplementary financial information and schedules audited (and, if

         financial information examined) by them and included or incorporated
         by reference in the Registration Statement or the Note Prospectus
         comply as to form in all material respects with the applicable
         accounting requirements of the Act and the Exchange Act and the
         related published rules and regulations thereunder; and if applicable,
         they have made a review in accordance with standards established by
         the American Institute of Certified Public Accountants of the

         the consolidated results of operations and financial position of MCN
         for the five most recent fiscal years included in the Note Prospectus
         and included or incorporated by reference in MCN's Annual Report on
         Form 10-K for the most recent fiscal year agrees with the
         corresponding amounts (after restatement and eliminations where
         applicable) in the audited consolidated financial statements for such
         five fiscal years which were included or incorporated by reference in
         MCN's Annual Reports on Form 10-K for such fiscal years;

             (iv)  On the basis of limited procedures, not constituting an
         audit in accordance with generally accepted auditing standards,
         including a reading of the unaudited consolidated financial statements
         and other information referred to below, a reading of the latest
         available unaudited interim consolidated financial statements of MCN
         and its subsidiaries, inspection of the minute books of MCN and its
         subsidiaries since the audited consolidated financial statements set
         forth in MCN's Annual Report on Form 10-K for the most recent year,

         as may be specified in such letter, nothing came to their attention 
         that caused them to believe that:

                          (A)  any unaudited consolidated financial statements
                 set forth in MCN's Quarterly Reports on Form 10-Q incorporated
                 by reference in the Registration Statement and the Note
                 Prospectus as amended or supplemented do not comply as to form
                 in all material respects with the applicable accounting
                 requirements of the Exchange Act as they apply to Form 10-Q
                 and the published rules and regulations thereunder or are not
                 presented in conformity with generally accepted accounting
                 principles applied on a basis substantially consistent with
                 that of the audited consolidated financial statements set
                 forth in MCN's Annual Report on Form 10-K for the most recent
                 year ended incorporated by reference in the Registration
                 Statement and the Note Prospectus as amended or supplemented;

                          (B)  any other unaudited income statement data and
                 balance sheet items included in the Note Prospectus do not
                 agree with the corresponding items in the unaudited
                 consolidated financial statements from which such data and
                 items were derived, and any such unaudited data and items were
                 not determined on a basis substantially consistent with the
                 basis for the corresponding amounts in the audited
                 consolidated financial statements included or incorporated by
                 reference in the Registration Statement and the Note
                 Prospectus as amended or supplemented;

                          (C)  any unaudited pro forma consolidated condensed
                 financial statements included or incorporated by reference in
                 the Note Prospectus as amended or supplemented do not comply
                 as to form in all material respects with the applicable
                 accounting requirements of the Act and the published rules and
                 regulations thereunder or the pro forma adjustments or
                 eliminations have not been properly applied to the historical
                 amounts in the compilation of those statements;

                          (D)  as of a specified date not more than five days
                 prior to the date of delivery of such letter, there have been
                 any decrease or increase in the common stock (except for any
                 increases in connection with any employee benefit, dividend
                 reinvestment or stock purchase plan of the Company) or any
                 increase or decrease in redeemable cumulative preferred
                 securities or long-term debt including capital lease
                 obligations (except for sinking fund and installment
                 requirements under their long- term debt agreements, terms of
                 the preferred securities of MCN Michigan and purchases in the
                 open market in anticipation thereof) or any





                                      -26-

                 increase in short-term debt, or any decrease in consolidated
                 common shareholder's equity of MCN and its consolidated
                 subsidiaries (other than periodic dividends declared to
                 stockholders and any decreases pursuant to the terms of the
                 preferred redeemable increase dividend equity securities of
                 MCN), in each case as compared with the corresponding amounts
                 shown in the latest consolidated statement of financial
                 position incorporated by reference in the Registration
                 Statement and the Note Prospectus as amended or supplemented,
                 except in all instances for increases or decreases which the
                 Note Prospectus as amended or supplemented, including
                 financial information incorporated by reference, discloses
                 have occurred or may occur or which are described in such
                 letter;

                          (E)  for the period from the date of the latest
                 consolidated financial statements or consolidating financial
                 statements included or incorporated by reference in the Note
                 Prospectus to the end of the latest period for which
                 consolidated financial statements are available there were any
                 decreases in consolidated operating revenues, operating
                 income, net income or earnings available for common stock of
                 MCN and its consolidated subsidiaries, or any increases in any
                 items specified by the Agents, in each case as compared with
                 the corresponding period in the preceding year and with any
                 other period of corresponding length specified by the Agents,
                 except in each case for increases or decreases which the Note
                 Prospectus as amended or supplemented, including financial
                 information incorporated by reference, discloses have occurred
                 or may occur or which are described in such letter; and

                          (F)  The unaudited consolidated financial statements
                 referred to in Clause (E) are not stated on a basis
                 substantially consistent with the audited consolidated
                 financial statements, incorporated by reference in the
                 Registration Statement and the Note Prospectus as amended or
                 supplemented.

                 (v)  In addition to the limited procedures, inspection of
         minute books, inquiries and other procedures referred to in clause
         (iii) and (iv) above, they have carried out certain other specified
         procedures, not constituting an audit in accordance with generally
         accepted auditing standards, with respect to certain amounts,
         percentages and financial information which are derived from the
         general accounting records of MCN and its subsidiaries, which appear
         in the Note Prospectus as amended or supplemented and the Registration
         Statement, in MCN's Annual Report on Form 10-K for the latest year
         ended and in any MCN Quarterly Report on





                                      -27-

  
<PAGE>   28

         Form 10-Q since the latest Annual Report on Form 10-K and which are
         specified by the Agents, and have compared certain of such amounts,
         percentages and financial information with the accounting records of
         MCN and its subsidiaries and have found them to be in agreement.

                 (g)  Other than as set forth or contemplated in the
Registration Statement and the Note Prospectus as amended or supplemented (i)
neither the Company, MCN nor any of their respective subsidiaries shall have
sustained since the date of the latest audited financial statements included or
incorporated by reference in the Registration Statement and the Note Prospectus
as amended or supplemented any material loss or interference with its business;
and (ii) since the respective dates as of which information is given in the
Registration Statement and the Note Prospectus as amended or supplemented there
shall not have been any change in the capital stock or long-term debt including
capital lease obligations (other than changes resulting from sinking fund and
installment provisions under any long-term debt agreement (scheduled payments
on lease obligations) to which the Company, MCN or any of their respective
subsidiaries is a party, terms of the preferred securities of MCN Michigan and
purchases in the open market in anticipation thereof) or any change, or any
development involving a prospective change, in or affecting the condition,
financial or otherwise, or in the earnings, business affairs or business
prospects of the Company or MCN and their respective subsidiaries, the effect
of which in any such case described in clause (i) or (ii) of this subsection
(g) is in the judgment of the Agents so material and adverse as to make it
impracticable or inadvisable to commence or continue the offering of the Notes
as contemplated by the Registration Statement or the Note Prospectus.

                 (h)      Subsequent to the date of this Agreement (1) no
downgrading shall have occurred in the rating accorded the debt securities of
the Company or MCN by any "nationally recognized securities rating
organization" as that term is defined by the Commission for the purposes of
Rule 436(g) of Regulation C, or (2) no review of the rating assigned to any
debt securities of the Company or MCN with a view to possible downgrading or
with negative implications for the Company or MCN, as the case may be, shall
have been announced.

                 (i)  The Company and MCN shall have furnished to the Agents
and counsel for the Agents, such further information, certificates and
documents as the Agents may reasonably request from time to time; and all
proceedings taken by the Company in connection with the issuance and sale of
Notes as herein contemplated shall be satisfactory in form and substance to the
Agents and counsel for the Agents.

                 If any of the conditions specified in this Section 4 shall not
have been fulfilled when and as provided in this Agreement (or, at the option
of the Agent, any applicable Terms Agreement by the Agent to purchase Notes as
principal), or if any of the opinions or certificates mentioned above or
elsewhere in this Agreement (or any applicable Terms Agreement) shall not be in
all material respects reasonably satisfactory in form and substance to an Agent
and its counsel, this Agreement (or any applicable Terms Agreement) with
respect to such Agent, and all obligations of such Agent hereunder or
thereunder, as the case may be, may be terminated by such Agent by notice to
the Company and MCN at any time and any such termination shall be without
liability of any party to any other party, except that the covenant regarding
provision of an earnings statement set forth in Section 3(d) hereof, the
provisions concerning payment of expenses under Section 10 hereof, the
indemnity and contribution agreement set forth in Sections 8 and 9 hereof, the
provisions concerning the representations and indemnities to survive set forth
in Section 12 hereof, the provisions relating to governing law set forth in
Section 16 and the provisions relating to successors set forth in Section 14
hereof shall remain in full force and effect.

                 5.  Delivery of and Payment for Notes Sold through the Agents.
Delivery of Notes sold through the Agent as agent shall be made by the Company
to the Agent for the account of any purchaser only against payment therefor in
immediately available funds.  In the event that a purchaser shall fail either
to accept delivery of or to make payment for a Note on the date fixed for
settlement, the Agent shall promptly notify the Company and deliver the Note to
the Company, and, if the Agent has theretofore paid the Company for such Note,
the Company will promptly return such funds to the Agent.  If such failure
occurred for any reason other than default by the Agent in the performance of
its obligations hereunder, the Company will reimburse the Agent for its loss of
the use of the funds for the period such funds were credited to the Company's
account.

                 6.  Additional Covenants of the Company and MCN.  Each of the
Company and MCN covenants and agrees with each Agent that:

                 (a)  Each acceptance by it of an offer for the purchase of
Notes (whether to the Agent as principal or through the Agent as agent), and
each delivery of Notes to the Agent (whether to the Agent as principal or
through the Agent as agent), shall be deemed to be an affirmation that the
representations and warranties of the Company and MCN contained in this
Agreement and in any certificate theretofore delivered to the Agent pursuant
hereto are true and correct at the time of such acceptance or sale, as the case
may be, and an undertaking that such representations and warranties will be
true and correct at the time of delivery to the purchaser or its agent, or to
the Agent, of the Note or Notes relating to such acceptance or sale, as the





                                      -29-

  
<PAGE>   30

case may be, as though made at and as of each such time (and it is understood
that such representations and warranties shall relate to the Registration
Statement and Note Prospectus as amended and supplemented to each such time).

                 (b)  Each time that (i) the Registration Statement or the Note
Prospectus is amended (which for the purposes of this Section 6 shall include
the filing by the Company or MCN of materials incorporated by reference in the
Registration Statement or the Note Prospectus) or supplemented (other than by
an amendment or supplement relating to any offering of securities other than
the Notes or providing solely for the terms of any Notes or for a change deemed
immaterial in the reasonable opinion of the Agents), (ii) the Prospectus is
supplemented to create a Note Prospectus, (iii) (if required in connection with
the purchase of the Notes by the Agent as principal) the Company sells Notes to
an Agent as principal or (iv) if the Company issues and sells Notes in a form
not previously certified to the Agents by the Company, the Company and MCN will
each deliver or cause to be delivered forthwith to each Agent a certificate
signed by its Chairman of the Board, President or a Vice President, and by its
chief financial or accounting officer, dated the date of the effectiveness of
such amendment, the date of filing of such supplement or materials, or the date
of such sale, as the case may be, in form and substance satisfactory to each
Agent, to the effect that the statements contained in the certificate referred
to in Section 4(e) that was last furnished to each Agent (either pursuant to
Section 4(e) or pursuant to this Section 6(b)) are true and correct at the time
of the effectiveness of such amendment (which for the purposes of this
Agreement in the case of the filing of materials incorporated by reference
shall be the date of the filing of such materials), the filing of such
supplement or the date of sale, as the case may be, as though made at and as of
such time (except that such statements shall be deemed to relate to the
Registration Statement, as amended at the time of effectiveness of such
amendment, and to the Prospectus or the Note Prospectus (as the case may be),
as amended and supplemented at the date of such certificate) or, in lieu of
such certificate, a certificate of the same tenor as the certificate referred
to in Section 4(e) but modified, as necessary, to relate to the Registration
Statement, as amended at the time of the effectiveness of such amendment, and
to the Prospectus or the Note Prospectus (as the case may be), as amended and
supplemented at the date of delivery of such certificate.

                 (c)  Each time that (i) the Registration Statement or the Note
Prospectus is amended or supplemented (which for the purposes of this Section 6
shall include the filing by the Company or MCN of materials incorporated by
reference in the Registration Statement or the Note Prospectus) or supplemented
(other than by an amendment or supplement relating to any offering of
securities other than the Notes or providing solely





                                      -30-

  
<PAGE>   31

for the terms of any Notes or for a change deemed immaterial in the reasonable
opinion of the Agents), (ii) the Prospectus is supplemented to create a Note
Prospectus, (iii) (if required in connection with the purchase of the Notes by
the Agent as principal) the Company sells Notes to an Agent as principal, or
(iv) if the Company issues and sells Notes in a form not previously certified
to the Agents by the Company, the Company and MCN shall furnish to or cause to
be furnished forthwith to each Agent a written opinion of Daniel L. Schiffer,
Esq., Senior Vice President, General Counsel and Secretary of MCN, and Vice
President, General Counsel and Secretary of the Company to the effect set forth
in Sections 4(b) but modified as necessary to relate to the Registration
Statement and the Note Prospectus as amended and supplemented to the time of
delivery of such opinion.  Any such opinion shall be dated the date of the
effectiveness of such amendment, the date of filing of such supplement or
materials or the date of such sale, as the case may be, in form and substance
satisfactory to each Agent.  In lieu of such opinion, such counsel may furnish
to each Agent a letter to the effect that each Agent may rely on such counsel's
last opinion to the same extent as though it were dated the date of such letter
authorizing reliance on such last opinion (except that statements in such last
opinion will be deemed to relate to the Registration Statement, as amended at
the time of the effectiveness of such amendment, and to the Prospectus or the
Note Prospectus (as the case may be), as amended and supplemented at the date
of delivery of such letter).

                 (d)  Each time that (i) the Registration Statement or the Note
Prospectus is amended or supplemented to set forth additional financial
information or there is filed with the Commission any document incorporated by
reference into the Note Prospectus which contains additional financial
information or (ii) (if required in connection with the purchase of the Notes
by the Agent as principal) the Company sells Notes to an Agent as principal,
the Company and MCN shall cause Deloitte & Touche LLP, its independent
auditors, forthwith to furnish each Agent with a letter, dated the date of the
effectiveness of such amendment, the date of filing of such supplement or
document or the date of such sale, as the case may be, in form and substance
satisfactory to each Agent, of the same tenor as the portions of the letter
referred to in subsections (i), (ii) and (iii) of Section 4(f), but modified to
relate to the Registration Statement and Note Prospectus, as amended and
supplemented to the date of such letter, and of the same tenor as the portions
of the letter referred to in subsections (iv) and (v) of Section 4(f), with
such changes as may be necessary to reflect changes in the financial statements
and other information derived from the accounting records of the Company.

                 7.  Right of Agent Who Agreed to Purchase as Principal to
Refuse to Purchase.  The Company and MCN agree that any Agent who has agreed to
purchase and pay for any Note as principal,





                                      -31-

  
<PAGE>   32

shall have the right to refuse to purchase such Note if, at the date of
delivery of such Note, either (a) any condition set forth in Section 4 shall
not be satisfied or (b) subsequent to the agreement to purchase such Note, any
change, or any development involving a prospective change, in or affecting the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of the Company or MCN and their respective subsidiaries, in
each case, considered as one enterprise, shall have occurred the effect of
which is, in the judgment of such Agent, so material and adverse as to make it
impractical or inadvisable to proceed with the delivery of such Note.
Notwithstanding the foregoing, under no circumstances shall any such Agent have
any duty or obligation to exercise the judgment permitted to be exercised under
this Section 7.

                 8.  Indemnification.  (a)  The Company and MCN jointly and
severally agree to indemnify and hold harmless each Agent and each person, if
any, who controls such Agent within the meaning of Section 15 of the 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), 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, Prospectus or
         Note 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; unless such
         untrue statement or omission or such alleged untrue statement or
         omission was made in reliance upon and in conformity with written
         information furnished to the Company or to MCN by the Agents expressly
         for use in the Registration Statement (or any amendment thereto) or
         any Preliminary Prospectus, Prospectus or Note Prospectus (or any
         amendment or supplement thereto);

             (ii)  against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, to the extent of the aggregate amount
         paid in settlement of any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement or
         omission, if such settlement is effected with the written consent of
         the Company and MCN; and





                                      -32-

  
<PAGE>   33

            (iii)  against any and all expense whatsoever, as incurred
         (including, the fees and disbursements of counsel chosen by the
         Agents), reasonably incurred in investigating, preparing or defending
         against any litigation, or 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.

                 (b)   Each Agent severally agrees to indemnify and hold
harmless the Company, MCN, their directors, each of their officers who signed
the Registration Statement, and each person, if any, who controls the Company
or MCN within the meaning of Section 15 of the Act against any and all loss,
liability, claim, damage and expense described in the indemnity contained in
subsection (a) of this Section, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in the
Registration Statement (or any amendment thereto) or any Preliminary
Prospectus, Prospectus or Note Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Company or to MCN by the Agents expressly for use in the Registration
Statement (or any amendment thereto) or such Preliminary Prospectus, Prospectus
or Note Prospectus (or any amendment or supplement thereto).

                 (c)  Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party shall not relieve such indemnifying party from any liability which it may
have otherwise than on account of this indemnity agreement.  An indemnifying
party may participate at its own expense in the defense of any such action.  In
no event shall the indemnifying parties be liable for fees and expenses of more
than one counsel (in addition to any local counsel) 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.

                 9.  Contribution.  In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 8 is for any reason held to be unavailable to or insufficient to hold
harmless the indemnified parties although applicable in accordance with its
terms, the Company and MCN, on the one hand, and the Agents, on the other hand,
shall contribute to the aggregate losses, liabilities, claims, damages and
expenses of the nature contemplated by said indemnity agreement incurred by the
Company and MCN, on the one hand, and one or more of the Agents, on the other
hand, as incurred, in such proportion so that each Agent is responsible for
that portion represented by the percentage that the total





                                      -33-

  
<PAGE>   34

commissions and underwriting discounts received by such Agent to the date of
such liability, and the Company and MCN are responsible for the balance;
provided, however, that no person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  For purposes of this Section, each person, if any, who
controls an Agent within the meaning of Section 15 of the Act shall have the
same rights to contribution as such Agent, and each director of the Company,
each officer of the Company who signed the Registration Statement, each
director of MCN, each officer of MCN who signed the Registration Statement, and
each person, if any, who controls the Company or MCN within the meaning of
Section 15 of the Act shall have the same rights to contribution as the
Company.

                 10.  Payment of Expenses.  Whether or not the transactions
contemplated hereunder are consummated or this Agreement is terminated, the
Company and MCN will pay all costs and expenses incident to the performance of
its obligations under this Agreement, including, without limiting the
generality of the foregoing:

                 (a)  The preparation, printing and filing of the Registration
Statement (including all exhibits thereto) and any amendments and supplements
thereto, and any Preliminary Prospectus, Prospectus or Note Prospectus, and any
amendments or supplements thereto;

                 (b)  The preparation, filing and reproduction of this
Agreement;

                 (c)  The preparation, printing, issuance and delivery of the
Notes, including fees and expenses relating to the use of book-entry notes;

                 (d)  The fees and disbursements of the Company's and MCN's
accountants and counsel, of the Trustee and its counsel, and of any Calculation
Agent;

                 (e)  The reasonable fees and disbursements of counsel to the
Agents incurred heretofore or hereafter in connection with the offering,
purchase and sale of the Notes;

                 (f)  The qualification of the Notes under state securities
laws, including filing fees and the reasonable fees and disbursements of
counsel for the Agents in connection therewith and in connection with the
preparation of any Blue Sky Survey and any Legal Investment Survey;

                 (g)  The printing and delivery to the Agents in quantities as

                           MCN INVESTMENT CORPORATION

                           ADMINISTRATIVE PROCEDURES

                          MEDIUM-TERM NOTES, SERIES B

                                  MAY 6, 1996

                 Medium-Term Notes, Series B, Due Nine Months or More from Date
of Issue (the "Notes") are to be offered on a continuing basis by MCN
Investment Corporation, a Michigan corporation (the "Company"), to or through
Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Smith
Barney Inc., Donaldson, Lufkin & Jenrette Securities Corporation and Salomon
Brothers Inc (each an "Agent" and, collectively, the "Agents"), pursuant to a
Distribution Agreement dated May 6, 1996 (the "Distribution Agreement") between
the Company, MCN Corporation ("MCN") and the Agents.  The Distribution
Agreement provides both for the sale of Notes by the Company to one or more of
the Agents as principal for resale to investors and other purchasers and for
the sale of Notes by the Company directly to investors (as may from time to
time be agreed to by the Company and the related Agent or Agents) in which case
the Agents will act as agents of the Company in soliciting Note purchases.  The
Notes will have the benefit of a Support Agreement dated as of September 1,
1995 between the Company and MCN.

                 Unless otherwise agreed by the related Agent or Agents and the
Company, Notes will be purchased by the related Agent or Agents as principal.
Such purchases will be made in accordance with terms agreed upon by the related
Agent or Agents and the Company (which terms shall be agreed upon orally, with
written confirmation prepared by the related Agent or Agents and mailed to the
Company).  If agreed upon by any Agent or Agents and the Company, such Agent or
Agents, acting solely as agent or agents for the Company and not as principal,
will use reasonable efforts to solicit offers to purchase the Notes.  Only
those provisions in these Administrative Procedures that are applicable to the
particular role that an Agent will perform shall apply.

                 The Notes will be issued as a series of securities pursuant to
an Indenture, dated as of September 1, 1995 (the "Indenture"), between the
Company and NBD Bank, as trustee, with respect to the Notes (the "Trustee").
In accordance with the provisions of the Indenture, NBD Bank has been duly
appointed by the Company as Transfer Agent and Paying Agent, in each case with
respect to the Notes.

                 A Registration Statement (the "Registration Statement", which
term shall include any additional registration statements
<PAGE>   43

or amendments thereto filed in connection with the Notes as provided in the
Distribution Agreement) with respect to the Notes has been filed with the
Securities and Exchange Commission (the "Commission").  The most recent base
Prospectus included in the Registration Statement, as supplemented with respect
to the Notes, is herein referred to as the "Prospectus".  The most recent
supplement to the Prospectus  setting forth the purchase price, interest rate,
maturity date and other terms of the Notes (as applicable) is herein referred
to as the "Pricing Supplement".

                 The Notes will either be issued (a) in book-entry form and
represented by one or more fully registered Notes (each, a "Book-Entry Note")
delivered to the Trustee, as agent for The Depository Trust Company ("DTC"),
and recorded in the book-entry system maintained by DTC, or (b) in certificated
form (each, a "Certificated Note") delivered to the investor or other purchaser
thereof or a person designated by such investor or other purchaser.  Owners of
beneficial interests in Notes issued in book-entry form will be entitled to
physical delivery of Notes in certificated form equal in principal amount to
their respective beneficial interests only upon certain limited circumstances
described in the Prospectus.

                 General procedures relating to the issuance of all Notes are
set forth in Part I hereof.  Additionally, Notes issued in book- entry form
will be issued in accordance with the procedures set forth in Part II hereof
and Notes issued in certificated form will be issued in accordance with the
procedures set forth in Part III hereof.  Capitalized terms used herein that
are not otherwise defined shall have the meanings ascribed thereto in the
Indenture or the Notes, as the case may be.

                                                  the account of the Company.

                                                  cancel and destroy the

                                                  that the Note was never
                                                  issued, and accordingly

</TABLE>

(1)  Earnings and fixed charges are defined and computed in accordance with
     Item 503 of Regulation S-K.

(2)  This amount represents the aggregate of (a) the pre-tax income from
     continuing operations of MCN Investment and its majority-owned
     subsidiaries, (b) MCN Investment's share of pre-tax income of its 50% owned
     companies, and (c) any income actually received from less than 50% owned
     companies.

(3)  Fixed charges added to earnings are adjusted to exclude interest
     capitalized during the period and, therefore, may differ from fixed charges
     as defined.

(4)  In April 1996, MCN announced its intention to sell The Genix Group, its
     computer services subsidiary.  For purposes of calculating the Ratio of
     Earnings to Fixed Charges, it has been classified as a discontinued
     operation and therefore excluded from the ratio for all periods presented.

(5)  Earnings for the year ended December 31, 1991 were not adequate to cover
     fixed charges.  The amount of the coverage deficiency was $1,736,000.

</TABLE>

(1)  Earnings and fixed charges are defined and computed in accordance with 
     Item 503 of Regulation S-K.

(2)  This amount represents the aggregate of (a) the pre-tax income from 
     continuing operations of MCN and its majority-owned subsidiaries, (b) 
     MCN's share of pre-tax income of its 50% owned companies, and (c) any 
     income actually received from less than 50% owned companies.

(3)  Fixed charges added to earnings are adjusted to exclude interest
     capitalized during the period for nonutility companies and the preferred
     securities dividend requirements of MichCon included in fixed charges but 
     not deducted in the determination of pre-tax income.

(4)  Fixed charges represent (a) interest, whether expensed or capitalized, (b)
     amortization of debt discount, premium and expense, (c) an estimate of 
     interest implicit in rentals, and (d) preferred securities dividend 
     requirements of subsidiaries (MichCon and MCN Limited Partnership), 
     increased to reflect the pre-tax earnings requirement for MichCon.

(5)  In April 1996, MCN announced its intention to sell The Genix Group, its
     computer services subsidiary.  For purposes of calculating the Ratio of 
     Earnings to Fixed Charges, it has been classified as a discontinued 
     operation and therefore excluded from the ratio for all periods presented.
