Ladies and Gentlemen:

              MCN Energy Enterprises Inc., formerly MCN Investment Corporation,
(the "Company"), a Michigan corporation and a wholly-owned subsidiary of MCN
Energy Group Inc. ("MCN"), a Michigan corporation, confirms its agreement with
Merrill Lynch & Co. Merrill Lynch, Pierce, Fenner & Smith Incorporated; Banc One
Capital Markets, Inc. and Salomon Smith Barney Inc. (each, an "Agent" and
collectively, the "Agents") with respect to the issue and sale by the Company of
its Medium-Term Notes, Series C, 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 Bank One Trust Company, NA, as trustee (the "Trustee"). As of the date
hereof, the Company has

<PAGE>   2
authorized the issuance and sale of up to $620,000,000 aggregate initial
offering price of the Notes to or through the Agents pursuant to the terms of
this Agreement. 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,
all 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.

              This Agreement provides for both the sale of the Notes by the
Company to one or more 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 applicable Agent), in
which case the applicable Agent will act as an agent of the Company in
soliciting offers for the purchase of the Notes.

              Section 1.  Solicitations as Agent; Purchases as Principal.

              (a) Appointment. Subject to the terms and conditions stated herein
and subject to the reservation by the Company of the right to sell Notes
directly on its own behalf, the Company hereby agrees that the Notes will be
sold exclusively to or through the Agents. 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 Prospectus Supplement (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


                                      -2-

<PAGE>   3
shall 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 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").

                                      -3-

<PAGE>   4


              (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
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.

<PAGE>   5


              (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 have filed with the Securities and
Exchange Commission (the "Commission"), as co-registrants, a registration
statement on Form S-3 (File No. 333-47137) for the registration under the
Securities Act of 1933, as amended (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 18, 1998. 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
properly registered on Form S-3 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 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 "Prospectus Supplement". Any reference herein to the Registration Statement,
any Preliminary Prospectus, the Prospectus, or the Prospectus Supplement, 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 Prospectus Supplement, 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 Prospectus Supplement 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 Prospectus


                                      -5-

<PAGE>   6
Supplement, 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 Prospectus Supplement 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 or any Rule 464(b) Registration Statement has been issued under the
Act and no proceeding for that purpose has been instituted or are pending or, to
the knowledge of the Company, are contemplated by the Commission, and any
request on the part of the Commission for additional information has been
complied with.

              (ii) Each of the Registration Statement and any Rule 462(b)
Registration Statement has become effective under the Act. At the respective
times the Registration Statement, any Rule 462(b) Registration Statement and any
post-effective amendments thereto (including the filing of the Company's most
recent Annual Report on Form 10-K, and any amendments thereto, with the
Commission) became effective and as of the date hereof, the Registration
Statement, any Rule 462 Registration Statement and any amendments or supplements
thereto complied and will comply in all material respects with the requirements
of the Act and rules and regulations thereunder (the "1933 Act Regulations") and
the Trust Indenture Act of 1939, as amended (the "1939 Act") and the rules and
regulations of the Commission under the 1939 Act (the "1939 Act Regulations")
and did not and will not contain an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading. Neither the Prospectus Supplement nor any
amendments or supplements thereto, at the time that the Prospectus Supplement or
any such amendment or supplement was issued and at the Representation Date,
included or will include an untrue statement of a material fact or omitted or
will omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. If the Company and MCN elect to rely upon Rule 434 of the 1933 Act
Regulations, the Company and MCN will comply with the requirements of Rule 434.
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 Supplement made in reliance upon and in conformity
with information furnished to the Company in writing by any Agent expressly for
use in the Registration Statement or the Prospectus Supplement.

              Each preliminary prospectus and prospectus filed as part of the
Registration Statement as originally filed or as part of any amendment thereto,
or filed pursuant to Rule 424



                                      -6-

<PAGE>   7
under the Act, complied when so filed in all material respects with the 1933
Act Regulations and each preliminary prospectus and the Prospectus Supplement
delivered to the Agents for use in connection with the offering of the Notes
will, at the time of such delivery, be identical to the electronically
transmitted copies thereof filed with the Commission pursuant to EDGAR, except
to the extent permitted by Regulation S-T.

              (iii) The documents incorporated or deemed to be incorporated by
reference in the Registration Statement and the Prospectus Supplement, at the
time they were or hereafter are filed with the Commission, complied and will
comply in all material respects with the requirements of the Exchange Act, and
the rules and regulations of Commission thereunder (the "Exchange Act
Regulations"), and, when read together with the other information in the
Prospectus Supplement, at the time the Registration Statement became effective,
at the time the Prospectus Supplement was issued and on the Representation Date,
did not and will not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were or
are made, not misleading.

              (iv) The accountants who certified the financial statements and
supporting schedules included or incorporated by reference in the Registration
Statement and the Prospectus Supplement are independent public accountants as
required by the Act and the 1933 Act Regulations.

              (v) The financial statements of MCN included or incorporated by
reference in the Registration Statement and the Prospectus Supplement, together
with the related schedules and notes, present fairly the financial position of
MCN and its consolidated subsidiaries at the dates indicated and the statements
of operations, stockholders' equity and cash flows of MCN and its consolidated
subsidiaries for the periods specified. Such financial statements have been
prepared in conformity with generally accepted accounting principles ("GAAP")
applied on a consistent basis throughout the periods involved. The supporting
schedules, if any, included or incorporated by reference in the Registration
Statement and the Prospectus Supplement present fairly in accordance with GAAP
the information required to be stated therein. The ratio of earnings to fixed
charges included in the Prospectus Supplement has been calculated in compliance
with Item 503(d) of Regulation S-K of the Commission. The selected financial
information and the summary financial data included in the Prospectus Supplement
present fairly the information shown therein and have been compiled on a basis
consistent with that of the audited financial statements included in the
Registration Statement.

              (vi) Since the respective dates as of which information is given
in the Registration Statement and the Prospectus Supplement, and except as
otherwise stated therein, (A) there has been no material adverse change and no
development which could reasonably be expected to result in a material adverse
change in the condition, financial or otherwise, or in the earnings, business
affairs or business prospects of the Company or MCN and their respective
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 MCN or any of their respective
subsidiaries, other than those arising in the ordinary course of business, which
are material with respect to the Company or MCN and their respective


                                      -7-

<PAGE>   8
subsidiaries, considered as one enterprise, (C) except for regular quarterly
dividends on the common stock of MCN in amounts per share that are consistent
with past practice or the applicable charter document or supplement thereto,
respectively, there has been no dividend or distribution of any kind declared,
paid or made by the Company or MCN on any class of its capital stock.

              (vii) 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 to conduct its business as presently conducted and as
described in the Prospectus Supplement and to enter into and perform its
obligations under, or as contemplated under, this Agreement. Each of the Company
and MCN is duly qualified as a foreign corporation to transact business and is
in good standing in each jurisdiction in which such qualification is required,
whether by reason of the ownership or leasing of property or the conduct of
business, except where the failure to so qualify or be in good standing would
not, singly or in the aggregate, have a Material Adverse Effect.

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

imposition of any lien, charge or encumbrance upon any property or assets of the
Company or MCN or any of their respective 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 MCN or any of their

covered thereby on the date of such certificate and at each Representation Date
subsequent thereto.

              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
Prospectus Supplement, or any amendment or supplement to the Prospectus
Supplement (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 Prospectus Supplement, and each Prospectus Supplement 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
Prospectus Supplement, including the filing of documents incorporated therein
by reference, (iii) of the filing of any amendment or supplement to the
Prospectus Supplement, including the filing of documents incorporated therein

                                      -13-
<PAGE>   14
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 Prospectus Supplement, or any amendment of or supplement to the
Prospectus Supplement, 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 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 Prospectus Supplement 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 Prospectus
Supplement 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
Prospectus Supplement which will correct such statement or omission or an
amendment which will effect such compliance and will supply such amended or
supplemented Prospectus Supplement 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).

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
deemed to be incorporated by reference therein) as the Agents may reasonably
request and (ii) as many copies of the Prospectus Supplement (as amended or
supplemented) as the Agents may reasonably request so long as the Agents are
required to deliver a Prospectus Supplement 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 Prospectus Supplement,
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 Prospectus
Supplement 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 Prospectus Supplement 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

shall cause the Registration Statement and the Prospectus Supplement 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
required by the Act or the Exchange Act and the rules and regulations of the
Commission thereunder.

              (n) The Company will use the net proceeds received by it from the
sale of the Notes in the manner specified in the Prospectus Supplement under the
caption "Use of Proceeds".

              4  Conditions to the Obligations of the Agents. The obligations of
each Agent to solicit offers to purchase the Notes as agent of the Company and
to purchase Notes as principal shall be subject to the accuracy of the

         Material Adverse Effect.

         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.

         Prospectus Supplement, all of the issued and outstanding capital stock
         of each such subsidiary of the Company and MCN has been duly authorized

         of preemptive or other similar rights of any securityholder of such
         subsidiary.

                   subsidiaries, or any increases in any items specified by the
                   Representatives, in each case as compared with the

                   period of corresponding length specified by the
                   Representatives, except in each case for increases or
                   decreases which the Prospectus, as amended or supplemented,
                   including financial information incorporated by reference,
                   discloses have occurred or may occur or which are described
                   in such letter; and

                        (F) the unaudited condensed consolidated financial
                   statements referred to in Clause (E) are not stated on a

                   Registration Statement and the Prospectus, as amended or
                   supplemented.

         amendments thereto, 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 MCN and its subsidiaries, which appear in the Prospectus, as
         amended or supplemented, and the Registration Statement, in MCN's
         Annual Report on Form 10-K, and any amendments thereto, for the latest
         year ended and in MCN's Quarterly Reports on Form 10-Q, and any
         amendments thereto, since the latest Annual Report on Form 10-K, and
         any amendments thereto, and which are specified by the Representatives,
         and have compared certain of such amounts, percentages and financial
         information with the accounting and financial records of MCN and its
         subsidiaries and have found them to be in agreement; and

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

              (g) 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.

              (h) 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

                                      -25-

<PAGE>   26
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 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 Prospectus Supplement
as amended and supplemented to each such time).

              (b) Each time that (i) the Registration Statement or the
Prospectus Supplement 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 Prospectus Supplement) 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 Prospectus Supplement, (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

                                      -26-
<PAGE>   27
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 Prospectus Supplement (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 Prospectus Supplement (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
Prospectus Supplement 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 Prospectus
Supplement) 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 Prospectus
Supplement, (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
Prospectus Supplement 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 Prospectus
Supplement (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
Prospectus Supplement is amended or supplemented to set forth additional
financial information or there is filed with the Commission any document
incorporated by reference into the Prospectus Supplement 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


                                      -27-

<PAGE>   28
and Prospectus Supplement, 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, 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 and Contribution. (a) The Company and MCN will
indemnify and hold harmless the Agents against any losses, claims, damages or
liabilities to which the Agents may become subject, under the Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement (or any
amendment thereto), the Prospectus (or any amendment or supplement thereto) or
any other prospectus relating to the Notes, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse the Agents for any
legal or other expenses reasonably incurred, as incurred, by the Agents in
connection with investigating or defending any such action or claim; provided,
however, that the Company and MCN shall not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in the Registration Statement (or any amendment thereto), the
Prospectus (or any amendment or supplement thereto) or any other prospectus
relating to the Notes, or any amendment or supplement thereto, in reliance upon
and in conformity with written information furnished to the Company and MCN by
the Agents expressly for use therein.

              (b) The Agents will indemnify and hold harmless the Company and
MCN against any losses, claims, damages or liabilities to which the Company and
MCN may become subject, under the Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon an untrue statement or alleged untrue statement of a material
fact contained in the Registration Statement (or any amendment thereto), the
Prospectus (or any amendment or supplement thereto) or any other prospectus
relating to the Notes, or any amendment or supplement thereto, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, in each case to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission was
made in the

                                      -28-

<PAGE>   29
Registration Statement (or any amendment thereto), the Prospectus (or any
amendment or supplement thereto) or any other prospectus relating to the Notes,
or any amendment or supplement thereto, in reliance upon and in conformity with
written information furnished to the Company and MCN by the Agents expressly for
use therein; and will reimburse the Company and MCN for any legal or other
expenses reasonably incurred, as incurred, by the Company and MCN in connection
with investigating or defending any such action or claim.

              (c) Promptly after receipt by an indemnified party under
subsection (a) or (b) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof but the omission so to notify the
indemnifying party shall not relieve it from any liability except to the extent
that it has been prejudiced in any material respect by such failure or from any
liability that it may have to any indemnified party otherwise than under such
subsection. In case any such action shall be brought against any indemnified
party and it shall notify the indemnifying party of the commencement thereof,
the indemnifying party shall be entitled to participate therein and, to the
extent that it shall wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and, after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under such subsection for any legal expenses of other counsel or any other
expenses, in each case subsequently incurred by such indemnified party, in
connection with the defense thereof other than reasonable costs of
investigation.

              (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company and MCN on the one hand and the Agents
on the other from the offering of the Notes to which such loss, claim, damage or
liability (or action in respect thereof) relates. If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law or if the indemnified party failed to give the notice required under
subsection (c) above and such indemnifying party was prejudiced in a material
respect by such failure, then each indemnifying party shall contribute to such
amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and MCN on the one hand and the Agents on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations. The relative benefits received by the
Company and MCN on the one hand and the Agents on the other shall be deemed to
be in the same proportion as the total net proceeds from such offering (before
deducting expenses) received by the Company and MCN bear to the total
commissions or discounts received by the Agents in respect thereof. The relative
fault shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the

                                      -29-
<PAGE>   30
omission or alleged omission to state a material fact relates to information
supplied by the Company and MCN or the Agents and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company, MCN and the Agents agree that it would not
be just and equitable if contribution pursuant to this subsection (d) were
determined by pro rata allocation or by any other method of allocation that does
not take account of the equitable considerations referred to above in this
subsection (d). The amount paid or payable by an indemnified party as a result
of the losses, claims, damages or liabilities (or actions in respect thereof)
referred to above in this subsection (d) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (d), the Agents shall not be required to
contribute any amount in excess of the amount by which the total public offering
price at which the Notes purchased by or through it were sold exceeds the amount
of any damages that the Agents have otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

              9  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 Prospectus Supplement,

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
hereinabove stated of copies of the Registration Statement and any amendments
thereto, and of the Prospectus Supplement and any amendments or supplements
thereto, and the delivery by the Agents of the


                                      -30-

<PAGE>   31
Prospectus Supplement and any amendments or supplements thereto in connection
with solicitation or confirmations of sales of the Notes;

              (h   The preparation, printing, reproducing and delivery to the
Agents of copies of the Indenture relating to the Notes;

              (i   Any fees charged by rating agencies for the rating of the
Notes;

              (j   The fees and expenses incurred in connection with the listing
of the Notes on any securities exchange;

              (k  The fees and expenses, if any, incurred with respect to any
filing with the National Association of Securities Dealers, Inc.;

              (l   Any advertising and other out-of-pocket expenses of the
Agents incurred with the approval of the Company;

              (m   The cost of providing any CUSIP or other identification
numbers for the Notes; and

              (n   The fees and expenses of any Depositary and any nominees
thereof in connection with the Notes.

              10. Termination. (a) This Agreement (excluding any Terms Agreement
hereunder by an Agent to purchase Notes as principal) may be terminated for any
reason, at any time either by the Company or by such Agent upon the giving of
thirty days' written notice of such termination to such Agent or the Company, as
the case may be.

              (b  Each Terms Agreement shall be subject to termination in the
absolute discretion of the Agent purchasing thereunder, immediately upon notice
given to the Company and MCN prior to the close of business on the Purchase Date
relating thereto (i) if there has been, since the date of the Terms Agreement or
since the respective dates as of which information is given in the Registration
Statement, 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 respective subsidiaries considered as one enterprise, whether or not
arising in the ordinary course of business, or (ii) if there shall have occurred
any material adverse change in the financial markets in the United States or any
outbreak or escalation of hostilities or other national or international
calamity or crisis the effect of which is such as to make it, in the judgment of
such Agent, impracticable to market the Notes or to enforce contracts for the
sale of the Notes, or (iii) if trading in the Common Stock of MCN has been
suspended by the Commission, or if trading generally on either the American
Stock Exchange or the New York Stock Exchange has been suspended, or minimum or
maximum prices for trading have been fixed, or maximum ranges for prices for
securities have been required, by either of said Exchanges or by order of the
Commission or any other governmental authority, or if a banking moratorium has
been declared by either Federal, New York or Michigan authorities or (iv) if the
rating assigned by any nationally recognized securities rating agency to any
debt securities of the Company or MCN as


                                      -31-

<PAGE>   32
of the date of any applicable principal purchase shall have been lowered since
that date or if any such rating agency shall have publicly announced that it has
under surveillance or review, with possible negative implications, its rating of
any debt securities of the Company or MCN, or (v) if there shall have come to
the Agent's attention any facts that would cause the Agent to believe that the
Prospectus Supplement, at the time it was required to be delivered to a
purchaser of Notes, included an untrue statement or a material fact or omitted
to state a material fact necessary in order to make the statements therein, in
light of the circumstances existing at the time of such delivery, not
misleading.

              (c  If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party except
that (i) each Agent shall be entitled to any commission earned in accordance
with Section 1(c) hereof, (ii) if at the time of termination (A) any Agent shall
own any Notes purchased by it as principal with the intention of reselling them
or (B) an offer to purchase any of the Notes has been accepted by the Company
but the time of delivery to the purchaser or his agent of the Note or Notes
relating thereto has not occurred, the covenants set forth in Sections 3 and 6
hereof shall remain in effect until such Notes are so resold or delivered, as
the case may be, and (iii) the covenant set forth in Section 3(d) hereof, the
provisions of Sections 8, 9, 10, 12, 13 and 15 hereof shall remain in full force
and effect.

              11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other certificates of
officers of the Company and MCN set forth in or made pursuant hereto or thereto
will remain in full force and effect, regardless of any investigation made by or
on behalf of any Agent or the Company or MCN or any of the officers, directors
or controlling persons referred to in Section 8 hereof, and will survive
delivery of and payment for any of the Notes.

              12. Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Agents, will be mailed,
delivered, telecopied or telegraphed and confirmed to it at the address

              13. Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and assigns and
the officers and directors and controlling persons referred to in Section 8
hereof, and no other person will have any right or obligation hereunder. The

                           MCN ENERGY ENTERPRISES INC.

                            ADMINISTRATIVE PROCEDURES

                           MEDIUM-TERM NOTES, SERIES C

                               SEPTEMBER 22, 1999

        Medium-Term Notes, Series C, Due Nine Months or More from Date of Issue
(the "Notes") are to be offered on a continuing basis by MCN Energy Enterprises
Inc, a Michigan corporation (the "Company"), to or through Merrill Lynch & Co.,
Merrill Lynch, Pierce, Fenner & Smith Incorporated, Banc One Capital Markets,
Inc. and Salomon Smith Barney Inc. (each an "Agent" and, collectively, the
"Agents"), pursuant to a Distribution Agreement dated September 22, 1999 (the
"Distribution Agreement") between the Company, MCN Energy Group Inc. ("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 Bank One Trust Company, NA, as trustee, with respect to the Notes (the
"Trustee"). In accordance with the provisions of the Indenture, Bank One Trust
Company, NA 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 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

<PAGE>   38

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.

                                                     respect to a Note, such Note will not be redeemable prior to

Calculation of                                       In case of Fixed Rate Notes, interest (including payments for
  Interest:                                          partial periods) will be calculated and paid on the basis of
                                                     a 360-day year of twelve 30-day months.

                                                     The interest rate on each Floating Rate Note will be
                                                     calculated by reference to the specified Base Rate or Rates
                                                     in either case plus or minus the applicable Spread, if any,
                                                     and/or multiplied by the applicable Spread Multiplier, if
                                                     any.

                                                     Unless otherwise provided in the applicable Pricing
                                                     Supplement, interest on each Floating Rate Note will be
                                                     calculated by multiplying its face amount by an accrued
                                                     interest factor. Such accrued interest factor is computed by
                                                     adding the interest factor calculated for each day in the
                                                     period for which accrued interest is being calculated.

                                                     for the reservation of one series of CUSIP numbers, which
                                                     series consists of approximately 900 CUSIP numbers which have
                                                     been reserved for and relating to Book-Entry Notes and the

                                                     list of such CUSIP numbers.  The Company will assign CUSIP

                                                     Bureau periodically of the CUSIP numbers that the Company has
                                                     assigned to Book-Entry Notes.  The Trustee will notify the

                                                     numbers remain unassigned to Book-Entry Notes, and, if it
                                                     deems necessary, the Company will reserve and obtain
                                                     additional CUSIP numbers for assignment to Book-Entry Notes.

Failure to Settle:                                   If the Trustee fails to enter an SDFS deliver order with
                                                     respect to a Book-Entry Note issued in book-entry form
                                                     pursuant to Settlement Procedure F, the Trustee may deliver
                                                     to DTC, through DTC's Participant Terminal System, as soon as

                                                     maintained at DTC.  DTC will process the withdrawal message,
                                                     provided that such participant account contains a principal

                                                     at least equal to the principal amount to be debited.  If

                                                     Notes represented by a Book-Entry Note, the Trustee will mark

                                                     by a Book-Entry Note, the Trustee will exchange such

                                                     agent, if the purchase price for any Book-Entry Note is not

                                                     will reimburse such Offering Agent for its loss of the use of
                                                     funds during the period when the funds were credited to the

                                                     its loss of the use of funds during the period when the funds
                                                     were credited to the account of the Company. Immediately upon

                                                     failure occurred, the Trustee will cancel and destroy the
                                                     Certificated Note, make appropriate entries in its records to
                                                     reflect the fact that the Note was never issued, and
                                                     accordingly notify in writing the Company.

         1.    This Note is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of September 1, 1995 (herein called the
"Indenture"), between the Company and Bank One Trust Company, NA (f/k/a NBD
Bank), as Trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered. As provided in the
Indenture, the Securities may be issued in one or more series which different
series may be issued in various aggregate principal amounts, may mature at
different times, may bear interest, if any, at different rates, may be subject
to different redemption provisions, if any, may be subject to different sinking,
purchase or analogous funds, if any, may be subject to different covenants and
Events of Default and may otherwise vary as in the Indenture provided or
permitted. This Note is one of a series designated on the face hereof as
Medium-Term Notes, Series C (the "Notes"), limited to $620,000,000 in aggregate
principal amount. The Notes of this series may be issued at various times with
different maturity dates and different principal repayment provisions, may bear
interest at different rates, and may otherwise vary, all as provided in the
Indenture.

         2.    A.  The regular record date (the "Regular Record Date") for a
Fixed Rate Note will be the fifteenth day, whether or not a Business Day, of the
calendar month immediately preceding the month in which the related Interest
Payment Date (as defined below) occurs and for a Floating Rate Note will be the
fifteenth day, whether or not a Business Day, immediately preceding the related
Interest Payment Date (as defined below) (unless otherwise shown on the face
hereof or specified in paragraph B below). Interest which is payable and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the person in whose name the Note is registered at the close of business on
the Regular Record Date for such Interest Payment Date; provided, however, that
interest payable on the Interest Payment Date occurring at Stated Maturity will
be to the person to whom principal shall be payable. "Maturity Date" means the
date on which the principal amount hereof becomes due and payable, whether at
Stated Maturity or earlier by declaration of acceleration, call for redemption,
repayment or otherwise. Notwithstanding the foregoing, any interest that is
payable but not punctually paid or duly provided for on any Interest Payment
Date shall forthwith cease to be payable to the registered owner hereof on such
Regular Record Date, and may be paid to the person in whose name such note is
registered on the close of business on a special record date (the "Special
Record Date") for the payment




                                       4

of such Defaulted Interest to be fixed by the Trustee, notice whereof having
been given to the Holder of such Note not less than ten days prior to such
Special Record Date, or may be paid at any time and in any other lawful manner,
or as more fully provided in the Indenture. The term "Business Day" as used
herein shall mean any day other than a Saturday or Sunday, which is (i) not a
day on which banking institutions or trust companies in the City of New York are
authorized or required by law, regulation or executive order to close and (ii)
if such Note is a LIBOR Note (as defined below), a London Business Day. "London
Business Day" with respect to any Note means any day on which dealings in
deposits in U.S. dollars are transacted in the London interbank market. In
connection with any calculations, all percentages resulting from any calculation
on Floating Rate Notes will be rounded, if necessary, to the nearest 1/100,000
of 1% (.0000001), with five one-millionths of a percentage point rounded
upwards, and all dollar amounts used in or resulting from such calculation on
Floating Rate Notes will be rounded to the nearest cent, with one-half cent
being rounded upwards.

         B.    If this is a Fixed Rate Note, the Company promises to pay
interest on the principal amount at the rate per annum shown on the face hereof
until the principal amount hereof is paid or duly made available for payment.
Unless otherwise provided on the face hereof, the Company will pay interest
semi-annually in arrears on March 1 and September 1 (each an "Interest Payment
Date"), commencing with the Interest Payment Date immediately following the
Original Issue Date shown on the face hereof and at the Maturity Date; provided,
however, that the first payment of interest on any Fixed Rate Note with an
Original Issue Date shown on the face hereof between a Regular Record Date and
an Interest Payment Date will be made on the Interest Payment Date following the
next succeeding Regular Record Date; provided, further, that any payment
required to be made on a date that is not a Business Day need not be made on
such date, but may be made on the next succeeding Business Day with the same
force and effect as if made on such date, and no additional interest shall
accrue as a result of such delayed payment. Unless otherwise specified on the
face hereof the Regular Record Date with respect to Interest Payment Dates
occurring on March 1 and September 1 shall be the preceding February 15 and
August 15, respectively. Interest will accrue from and including the most recent
Interest Payment Date or, if no interest has been paid or duly provided for,
from and including the Original Issue Date on the face hereof, to, but excluding
the Interest Payment Date. The amount of such interest payable on any Interest
Payment Date shall be computed on the basis of a 360-day year of twelve 30-day
months.

         C.    If this is a Floating Rate Note, the Company promises to pay
interest on the principal amount at the rate per annum determined in accordance
with the provisions below under the heading "Determination of CD Rate",
"Determination of CMT

Rate", "Determination of Commercial Paper Rate", "Determination of Eleventh
District Cost of Funds Rate", "Determination of Federal Funds Rate",
"Determination of LIBOR", "Determination of Prime Rate" or "Determination of
Treasury Rate", depending upon whether the Base Rate specified above is CD Rate,
CMT Rate, Commercial Paper Rate, Eleventh District Cost of Funds Rate, Federal
Funds Rate, LIBOR, Prime Rate or Treasury Rate, respectively, and in accordance
with any applicable provisions on the face hereof under the heading "Other
Provisions", until the principal hereof is paid or duly made available for
payment. The Company will pay interest monthly, quarterly, semi-annually or
annually as specified on the face hereof under "Interest Payment Period",
commencing with the first Interest Payment Date specified on the face hereof
next succeeding the Original Issue Date, and at the Maturity Date; provided,
however, that the first payment of interest on any Floating Rate Note with an
Original Issue Date shown on the face hereof between a Regular Record Date and
an Interest Payment Date will be made on the Interest Payment Date following the
next succeeding Regular Record Date. Unless otherwise provided on the face
hereof and below, interest will be payable, in the case of Floating Rate Notes
that reset daily, weekly, or monthly, on the third Wednesday of each month or on
the third Wednesday of March, June, September and December of each year, as
specified on the face hereof; in the case of Floating Rate Notes that reset
quarterly, on the third Wednesday of March, June, September and December of each
year; in the case of Floating Rate Notes that reset semiannually, on the third
Wednesday of each of two months of each year specified on the face hereof; and
in the case of Floating Rate Notes that reset annually, on the third Wednesday
of the one month of each year specified on the face hereof (each such day being
an "Interest Payment Date") and, in each case, on the Maturity Date. If any
Interest Payment Date for any Floating Rate Note (other than the Stated
Maturity) would otherwise be a day that is not a Business Day, such Interest
Payment Date will be postponed to the next succeeding day that is a Business
Day, except that in the case of a LIBOR Note, if such Business Day falls in the
next succeeding calendar month, such Interest Payment Date will be the
immediately preceding Business Day. If the Stated Maturity of a Floating Rate
Note falls on a day that is not a Business Day, the required payment of
principal, premium, if any, and/or interest will be made on the next succeeding
Business Day as if made on the date such payment was due, and no interest shall
accrue on such payment for the period from and after the Stated Maturity to the
date of such payment on the next succeeding Business Day.

         The interest payable on a Floating Rate Note on each Interest Payment
Date will include accrued interest from and including the Original Issue Date or
from and including the last date in respect of which interest has been paid or
duly provided for, as the case may be, to but excluding such Interest Payment
Date or the Maturity Date, as the case may be. Such accrued interest will be
calculated by multiplying the principal amount of such Note by an accrued
interest factor. Such accrued




                                       6



<PAGE>   7


interest factor will be computed by adding the interest factor calculated for
each day in the period for which accrued interest is being calculated. Unless
otherwise specified on the face hereof, the interest factor (expressed as a
decimal calculated to seven decimal places without rounding) for each such day
is computed by dividing the interest rate in effect on such day by 360, if the
Base Rate is CD Rate, Commercial Paper Rate, Eleventh District Cost of Funds
Rate, LIBOR, Federal Funds Rate or Prime Rate, or by the actual number of days
in the year if the Base Rate is the CMT Rate or the Treasury Rate, as indicated
on the face hereof. For purposes of making the foregoing calculation, the
interest rate in effect on any Interest Reset Date will be the applicable rate
as reset on such date. The interest rate in effect from the Original Issue Date
to the first Interest Reset Date (the "Initial Interest Rate") will be
determined as if the Original Issue Date were an Interest Reset Date.
Notwithstanding the foregoing, the interest rate hereon shall not be greater
than the Maximum Interest Rate, if any, or less than the Minimum Interest Rate,
if any, shown on the face hereof. In addition, the interest rate hereon shall in
no event be higher than the maximum rate, if any, permitted by Michigan law, as
the same may be modified by United States law of general application. Commencing
with the first Interest Reset Date specified on the face hereof following the
Original Issue Date and thereafter upon each succeeding Interest Reset Date
specified on the face hereof, the rate at which interest on a Floating Rate Note
is payable shall be adjusted as specified on the face hereof under Interest
Reset Period; provided, however, that if any Interest Reset Date would otherwise
be a day that is not a Business Day, such Interest Reset Date shall be postponed
to the next day that is a Business Day, except that (i) if the Base Rate is
LIBOR and such Business Day is in the next succeeding calendar month, such
Interest Reset Date shall be the immediately preceding Business Day or (ii) if
the Base Rate is Treasury Rate and the Interest Reset Date falls on a date which
is an auction date, the Interest Reset Date shall be the following day that is a
Business Day.

         The interest rate applicable to each Interest Reset Period commencing
on the Interest Reset Date will be the rate determined as of the applicable
Interest Determination Date on or prior to the related Calculation Date (as
defined below). The "Interest Determination Date" with respect to the CD Rate,
CMT Rate, Commercial Paper Rate, Federal Funds Rate and Prime Rate will be the
second Business Day immediately preceding the applicable Interest Reset Date and
the Interest Determination Date with respect to LIBOR will be the second London
Business Day immediately preceding the applicable Interest Reset Date. With
respect to the Eleventh District Cost of Funds Rate, the Interest Determination
Date will be the last working day of the month immediately preceding each
Interest Reset Date on which the




                                       7

Federal Home Loan Bank of San Francisco publishes the Index. With respect to the
Treasury Rate, the Interest Determination Date will be the day in the week in
which the applicable Interest Reset Date falls on which day direct obligations
of the United States ("Treasury Bills") of the Index Maturity specified on the
face hereof are normally auctioned. Treasury Bills are normally sold at an
auction held on Monday of each week, unless that day is a legal holiday, in
which case the auction is normally held on the following Tuesday, except that
such auction may be held on the preceding Friday; provided, however, that if an
auction is held on the Friday of the week preceding the applicable Interest
Reset Date, the Interest Determination Date will be such preceding Friday.

         Unless otherwise provided on the face hereof, the "Calculation Date",
if applicable, pertaining to any Interest Determination Date will be the earlier
of (i) the tenth calendar day after such Interest Determination Date, or, if
such day is not a Business Day, the next succeeding Business Day or (ii) the
Business Day immediately preceding the applicable Interest Payment Date or the
Maturity Date, as the case may be.

         Subject to applicable provisions of law and except as specified herein,
on each Interest Reset Date the rate of interest shall be the rate determined in
accordance with the provisions of the applicable heading below.

Determination of CD Rate. If the Base Rate indicated on the face hereof is the
CD Rate, the interest rate shall equal the rate on the Interest Determination
Date specified on the face hereof for negotiable certificates of deposit having
the Index Maturity specified on the face hereof as published by the Board of
Governors of the Federal Reserve System in "Statistical Release H.15(519),
Selected Interest Rates", or any successor publication of the Board of Governors
of the Federal Reserve System ("H.15(519)") under the heading "CDs (Secondary
Market)" or, if not so published by 3:00 p.m., New York City time, on the
related Calculation Date, the rate on such Interest Determination Date for
negotiable certificates of deposit of the Index Maturity designated on the face
hereof as published by the Federal Reserve Bank of New York in its daily
statistical release "Composite 3:30 P.M. Quotations for U.S. Government
Securities" or any successor publication ("Composite Quotations") under the
heading "Certificates of Deposit." If such rate is not published by either
H.15(519) or Composite Quotations by 3:00 p.m., New York City time, on the
related Calculation Date, then the CD Rate on such Interest Determination Date
will be calculated by the Calculation Agent and will be the arithmetic mean of
the secondary market rates as of 10:00 a.m., New York City time, on such
Interest Determination Date of three leading nonbank dealers in negotiable U.S.
dollar certificates of deposit in The City of New York (which may include any of
the Agents or their affiliates) selected by the




                                        8

Calculation Agent for negotiable certificates of deposit of major United States
money market banks for negotiable certificates of deposit with a remaining
maturity closest to the Index Maturity designated on the face hereof in an
amount that is representative for a single transaction in that market at that
time. In each of the above cases, the rate shall be adjusted by the addition or
subtraction of the Spread, if any, specified on the face hereof, or by
multiplication by the Spread Multiplier, if any, specified on the face hereof.
If the dealers selected as aforesaid by the Calculation Agent are not quoting
rates as mentioned in this sentence, the CD Rate determined as of such Interest
Determination Date will be the CD Rate in effect on such Interest Determination
Date.

Determination of CMT Rate. If an Interest Rate Basis for this Note is specified
on the face hereof as the CMT Rate, the CMT Rate shall be determined as of the
applicable Interest Determination Date (a "CMT Rate Interest Determination
Date") as the rate displayed on the Designated CMT Telerate Page (as defined
below) under the caption "...Treasury Constant Maturities...Federal Reserve
Board Release H.15...Mondays Approximately 3:45 P.M.", under the column for the
Designated CMT Maturity Index (as defined below) for (i) if the Designated CMT
Telerate Page is 7051, or any other page as may replace such page on such
service, the rate on such CMT Rate Interest Determination Date and (ii) if the
Designated CMT Telerate Page is 7052, or any other page as may replace such page
on such service, the weekly or monthly average, as specified on the face hereof,
for the week or month, as applicable, ended immediately preceding the week or
month, as applicable, in which such CMT Rate Interest Determination Date falls.
If such rate is no longer displayed on the relevant page or is not so displayed
by 3:00 P.M., New York City time, on the related Calculation Date, then the CMT
Rate for such CMT Rate Interest Determination Date will be such treasury
constant maturity rate for the Designated CMT Maturity Index as published in
H.15(519). If such rate is no longer published or is not so published by 3:00
P.M., New York City time, on the related Calculation Date, then the CMT Rate on
such CMT Rate Interest Determination Date will be such treasury constant
maturity rate for the Designated CMT Maturity Index (or other United States
Treasury rate for the Designated CMT Maturity Index) for such CMT Rate Interest
Determination Date as may then be published by either the Board of Governors of
the Federal Reserve System or the United States Department of the Treasury that
the Calculation Agent determines to be comparable to the rate formerly displayed
on the Designated CMT Telerate Page and published in H.15(519). If such
information is not so provided by 3:00 P.M., New York City time, on the related
Calculation Date, then such CMT Rate on the CMT Rate Interest Determination Date
will be calculated by the Calculation Agent and will be a yield to maturity,
based on the arithmetic mean of the secondary market offered rates as of
approximately 3:30 P.M., New York City time, on such CMT Rate Interest
Determination Date reported, according



                                       9

<PAGE>   10


to their written records, by three leading primary United States government
securities dealers (each, a "Reference Dealer") in The City of New York selected
by the Calculation Agent (from five such Reference Dealers selected by the
Calculation Agent and eliminating the highest quotation (or, in the event of
equality, one of the highest) and the lowest quotation (or, in the event of
equality, one of the lowest)), for the most recently issued direct noncallable
fixed rate obligations of the United Stated ("Treasury Notes") with an original
maturity of approximately the Designated CMT Maturity Index and a remaining term
to maturity of not less than such Designated CMT Maturity Index and a remaining
term to maturity of not less than such Designated CMT Maturity Index minus one
year. If the Calculation Agent is unable to obtain three such Treasury Note
quotations, the CMT Rate on such CMT Rate Interest Determination Date will be
calculated by the Calculation Agent and will be a yield to maturity based on the
arithmetic mean of the secondary market offered rates as of approximately 3:30
P.M., New York City time , on such CMT Rate Interest Determination Date of three
Reference Dealers in The City of New York (from five such Reference Dealers
selected by the Calculation Agent and eliminating th highest quotation (or, in
the event of equality, one of the highest) and the lowest quotation (or, in the
event of equality, one of the lowest)),for Treasury Notes with an original
maturity of the number of years that is the next highest to the Designated CMT
Maturity Index and a remaining term to maturity closet to the Designated CMT
Maturity Index and in an amount of at least U.S. $100 million. If three or four
(and not five) of such Reference Dealers are quoting as described above, then
the CMT Rate will be calculated by the Calculation Agent based on the arithmetic
mean of the offered rates obtained and neither the highest nor the lowest of
such quotes will be eliminated; provided, however, that if fewer than three
Reference Dealers selected by the Calculation Agent are quoting as mentioned
herein, the CMT Rate determined as of such CMT Rate Interest Determination Date
will be the CMT Rate in effect on such CMT Rate Interest Determination Date. If
two Treasury Notes with an original maturity as described in the second
preceding sentence have remaining terms to maturity equally close to the
Designated CMT Maturity Index, the Calculation Agent will obtain from five
Reference Dealers quotations for the Treasury Note with the shorter remaining
term to maturity. In each of the above cases, the rate shall be adjusted by the
addition or subtraction of the Spread, if any, specified on the face hereof, or
by multiplication by the Spread Multiplier, if any, specified on the face
hereof.

        "Designated CMT Telerate Page" means the display on Bridge Telerate,
Inc. (or any successor service) on the page specified on the face hereof (or any
other page as may replace such page on such service) for the purpose of
displaying Treasury Constant Maturities as reported in H.15(519) or, if no such
page is specified on the face hereof, page 7052.


                                       10

<PAGE>   11


         "Designated CMT Maturity Index" means the original period to maturity
of the United States Treasury securities (either 1, 2, 3, 5, 7, 10, 20, or 30
years) specified on the face hereof with respect to which the CMT Rate will be
calculated or, if no such maturity is specified on the face hereof, 2 years.

Determination of Commercial Paper Rate. If the Base Rate indicated on the face
hereof is the Commercial Paper Rate, the interest rate shall equal the Money
Market Yield (as defined below) on the Interest Determination Date specified on
the face hereof of the rate for commercial paper having the Index Maturity
specified on the face hereof, as such rate shall be published in H.15(519) under
the heading "Commercial Paper-Nonfinancial." In the event that such rate is not
published by 3:00 p.m., New York City time, on the related Calculation Date,
then the Commercial Paper Rate will be the Money Market Yield on such Interest
Determination Date of the rate for commercial paper of the Index Maturity
specified on the face hereof as published in H.15 Daily Update, or other
recognized electronic source used for the purpose of displaying the applicable
rate, under the caption "Commercial Paper-Nonfinancial." If by 3:00 p.m., New
York City time, on the related Calculation Date such rate is not yet published
in either H.15(519) or Composite Quotations, then the Commercial Paper Rate on
such Interest Determination Date will be calculated by the Calculation Agent and
will be the Money Market Yield of the arithmetic mean of the offered rates, at
approximately 11:00 a.m., New York City time, on such Interest Determination
Date of three leading dealers of commercial paper in The City of New York (which
may include any of the Agents or their affiliates) selected by the Calculation
Agent for commercial paper having the Index Maturity designated on the face
hereof placed for industrial issuers whose bonds are rated "AA", or the
equivalent, from a nationally recognized statistical rating organization. In
each of the above cases, the rate shall be adjusted by the addition or
subtraction of the Spread, if any, specified on the face hereof, or by
multiplication by the Spread Multiplier, if any, specified on the face hereof.
If the dealers selected as aforesaid are not quoting rates described in this
sentence, the Commercial Paper Rate will be the Commercial Paper Rate in effect
on such Interest Determination Date.

         "Money Market Yield" means yield (expressed as a percentage) calculated
in accordance with the following formula:



         Money Market Yield =                    D x 360       x 100
                                           ------------------
                                             360 - (D x M)

where "D" refers to the applicable per annum rate for commercial paper quoted on
a bank discount basis and expressed as a decimal, and "M" refers to the actual
number of days in the interest period for which interest is being calculated.

Determination of Eleventh District Cost of Funds Rate. If the Base Rate for this
Note is indicated on the face hereof as Eleventh District Cost of Funds Rate,
the Eleventh District Cost of Funds Rate shall be determined as of the
applicable Interest Determination Date (an "Eleventh District Cost of Funds Rate
Interest Determination Date") as the rate equal to the monthly weighted average
cost of funds for the calendar month immediately preceding the month in which
such Eleventh District Cost of Funds Rate Interest Determination Date falls, as
set forth under the caption "11th District" on the display on Bridge Telerate,
Inc. (or any successor service) on page 7058 or any other page as may replace
such page on such service ("Telerate Page 7058") as of 11:00 A.M., San Francisco
time, on such Eleventh District Cost of Funds Rate Interest Determination Date.
If such rate does not appear on Telerate Page 7058 on such Eleventh District
Cost of Funds Rate Interest Determination Date, then the Eleventh District Cost
of Funds Rate on such Eleventh District Cost of Funds Rate Interest
Determination Date shall be the monthly weighted average cost of funds paid by
member institutions of the Eleventh Federal Home Loan Bank District ("FHLB")that
was most recently announced (the"Index") by the FHLB of San Francisco as such
cost of funds for the calendar month immediately preceding such Eleventh
District Cost of Funds Rate Interest Determination Date. In each of the above
cases, the rate shall be adjusted by the addition or subtraction of the Spread,
if any, specified on the face hereof, or by multiplication by the Spread
Multiplier, if any, specified on the face hereof. If the FHLB of San Francisco
fails to announce the Index on or prior to such Eleventh District Cost of Funds
Rate Interest Determination Date for the calendar month immediately preceding
such Eleventh District Cost of Funds Rate Interest Determination Date, the
Eleventh District Cost of Funds Rate determined as of such Eleventh District
Cost of Funds Rate Interest Determination Date will be the Eleventh District
Cost of Funds Rate in effect on such Eleventh District Cost of Funds Rate
Interest Determination Date.

Determination of Federal Funds Rate. If the Base Rate indicated on the face
hereof is the Federal Funds Rate, the interest rate shall equal the rate on the
Interest Determination Date specified on the face hereof for federal funds as
published in H.15(519) under the heading "Federal Funds (Effective)" or, if not
so published by 3:00 p.m., New York City time, on the related Calculation Date,
the rate on such Interest Determination Date as published in H.15 Daily Update,
or other recognized electronic source used for the purpose of displaying the
applicable rate, under the caption "Federal Funds (Effective)." If by 3:00 p.m.,
New York City time, on the related Calculation Date such rate is not published
in either H.15(519) or Composite Quotations, then the Federal Funds Rate on such
Interest Determination Date will be calculated by the Calculation Agent and will
be the arithmetic mean of the rates for the last transaction in overnight United



                                       12

<PAGE>   13


States dollar federal funds arranged by three leading brokers of federal funds
transactions in The City of New York (which may include any of the Agents or
their affiliates) selected by the Calculation Agent prior to 9:00 a.m., New York
City time, on such Interest Determination Date. In each of the above cases, the
rate shall be adjusted by the addition or subtraction of the Spread, if any,
specified on the face hereof, or by multiplication by the Spread Multiplier, if
any, specified on the face hereof. If the brokers selected as aforesaid by the
Calculation Agent are not quoting as mentioned in this sentence, the Federal
Funds Rate determined as of such Interest Determination Date will be the Federal
Funds Rate in effect on such Interest Determination Date.

Determination of LIBOR. If the Base Rate indicated on the face hereof is LIBOR,
the interest rate with respect to the Interest Determination Date specified on
the face hereof shall be determined in accordance with the following provisions:

        (i)   With respect to an Interest Determination Date, LIBOR will be
    either: (a) if "LIBOR Reuters" is specified on the face hereof, the
    arithmetic mean of the offered rates (unless the specified Designated LIBOR
    Page by its terms provides for only a single rate, in which case such single
    rate shall be used) for deposits in U.S. dollars having the Index Maturity
    specified on the face hereof, commencing on the second London Business Day
    immediately following such Interest Determination Date, which appear on the
    Reuters Screen LIBO Page as of 11:00 a.m., London time, on such Interest
    Determination Date, if at least two such rates appear (unless, as aforesaid,
    only a single rate is required) on the Reuters Screen LIBO Page ("LIBOR
    Reuters"), or (b) if "LIBOR Telerate" is specified on the face hereof or if
    neither "LIBOR Reuters" nor "LIBOR Telerate" is specified as the method for
    calculating LIBOR, the rate for deposits in U.S. dollars having the Index
    Maturity designated on the face hereof, commencing on the second London
    Business Day immediately following such Interest Determination Date, that
    appears on the Telerate Page 3750 as of 11:00 a.m., London time, on such
    Interest Determination Date ("LIBOR Telerate").

        (ii)  With respect to an Interest Determination Date on which fewer than
    two offered rates appear, or no rate appears, as the case may be, on the
    designated LIBOR page as specified above, LIBOR will be determined on the
    basis of the rates at which deposits in U.S. dollars having the Index
    Maturity designated on the face hereof are at approximately 11:00 a.m.,
    London time, on such Interest Determination Date by four reference major
    banks ("Reference Banks") in the London interbank market selected by the
    Calculation Agent to prime banks in the London interbank market commencing
    on the second London Business Day immediately following such Interest
    Determination Date and in a principal amount that is representative for a
    single




                                       13

<PAGE>   14


    transaction in such market at such time. The Calculation Agent will request
    the principal London office of each of the Reference Banks to provide a
    quotation of its rate. If at least two such quotations are provided, LIBOR
    for such Interest Determination Date will be the arithmetic mean of such
    quotations. If fewer than two quotations are provided, LIBOR for such
    Interest Determination Date will be the arithmetic mean of the rates quoted
    at approximately 11:00 a.m., New York City time, on such Interest
    Determination Date by three major banks (which may include the Agents) in
    The City of New York selected by Calculation Agent for loans in U.S. dollars
    to leading European banks having the specified Index Maturity designated on
    the face hereof and in a principal amount that is representative for a
    single transaction in such market at such time; provided, however, that if
    the banks selected as aforesaid by the Calculation Agent are not quoting as
    mentioned in this sentence, LIBOR determined as of such Interest
    Determination Date will be LIBOR in effect on such Interest Determination
    Date.

    In each of the above cases, the rate shall be adjusted by the addition or
    subtraction of the Spread, if any, specified on the face hereof, or by
    multiplication by the Spread Multiplier, if any, specified on the face
    hereof.

    Unless otherwise indicated on the face hereof, "Reuters Screen LIBO Page"
    means the display designated as Page "LIBO" on the Reuters Monitor Money
    Rate Service (or such other page as may replace the LIBO page on that
    service for the purpose of displaying London interbank rates of major
    banks). "Telerate Page 3750" means the display designated as page "3750" on
    the Bridge Telerate Inc. (or such other page as may replace the 3750 page on
    that service or such other service or service as may be nominated by the
    British Bankers' Association for the purpose of displaying London interbank
    rates for U.S. dollar deposits).

Determination of Prime Rate. If the Base Rate, indicated on the face hereof is
the Prime Rate, the interest rate shall equal the rate on the Interest
Determination Date specified on the face hereof as published in H.15(519) under
the heading "Bank Prime Loan." If such rate is not published prior to 3:00 p.m.,
New York time, on the related Calculation Date, then the Prime Rate shall be the
arithmetic mean of the rates of interest publicly announced by at least four
banks that appear on the Reuters Screen USPRIME1 Page (as defined below) as such
bank's prime rate or base lending rate as in effect for such Interest
Determination Date. If fewer than four such rates appear on the Reuters Screen
USPRIME1 Page for such Interest Determination Date, the Prime Rate shall be the
arithmetic mean of the prime rates or base lending rates quoted on the basis of
the actual number of days in the year divided by a 360-day year as of the close
of business on such Interest



                                       14

<PAGE>   15

Determination Date by four major money center banks in The City of New York
selected by the Calculation Agent. If fewer than two such rates appear on the
Reuters Screen USPRIME1 Page, the Prime Rate will be determined by the
Calculation Agent on the basis of the rates furnished in The City of New York by
three substituted banks or trust companies organized and doing business under
the laws of the United States, or any State thereof, having total equity capital
of at least $500 million and being subject to supervision or examination by
Federal or State authority, selected by the Calculation Agent to provide such
rate or rates. In each of the above cases, the rate shall be adjusted by the
addition or subtraction of the Spread, if any, specified on the face hereof, or
by multiplication by the Spread Multiplier, if any, specified on the face
hereof. If the banks or trust companies selected as aforesaid are not quoting as
mentioned in the second preceding sentence, the Prime Rate determined as of such
Interest Determination Date will be the Prime Rate in effect on such Interest
Determination Date.

         "Reuters Screen USPRIME1 Page" means the display designated as page
"USPRIME1" on the Reuters Monitor Money Rates Service (or such other page as may
replace the USPRIME1 page on that service for the purpose of displaying prime
rates or base lending rates of major United States banks).

Determination of Treasury Rate. If the Base Rate indicated on the face hereof is
the Treasury Rate, the interest rate shall equal the rate on the Interest
Determination Date specified on the face hereof applicable to the most recent
auction of direct obligations of the United States ("Treasury Bills") having the
Index Maturity specified on the face hereof, as such rate shall be published in
H.15(519) under the heading "Treasury Bills -- auction average (investment)" or,
in the event that such rate is not published by 3:00 p.m., New York City time,
on the related Calculation Date, the auction average rate (expressed as a bond
equivalent on the basis of a year of 365 or 366 days, as applicable, and applied
on a daily basis) as otherwise announced by the United States Department of the
Treasury. In the event that the results of the auction of Treasury Bills having
the Index Maturity designated on the face hereof are not published or reported
as provided above by 3:00 p.m., New York City time, on such Calculation Date, or
if no such auction is held in a particular week, then the Treasury Rate will be
calculated by the Calculation Agent and will be a yield to maturity (expressed
as a bond equivalent on the basis of a year of 365 or 366 days, as applicable,
and applied on a daily basis) of the arithmetic mean of the secondary market bid
rates, as of approximately 3:30 p.m., New York City time, on such Interest
Determination Date, of three leading primary United States government securities
dealers (which may include any of the Agents or their affiliates) selected by
such Calculation Agent for the issue of Treasury Bills with a remaining maturity
closest to the Index Maturity specified on the




                                       15

face hereof. In each of the above cases, the rate shall be adjusted by the
addition or subtraction of the Spread, if any, specified on the face hereof, or
by multiplication by the Spread Multiplier, if any, specified on the face
hereof. If the dealers selected as aforesaid by the Calculation Agent are not
quoting bid rates as described in this sentence, then the Treasury Rate
determined as of such Interest Determination Date will be the Treasury Rate in
effect on such Interest Determination Date.

         3.   Unless otherwise specified on the face hereof, Bank One Trust
Company, NA, shall be the Calculation Agent. The Calculation Agent shall
calculate the interest rate in accordance with the foregoing and will confirm in
writing such calculation to the Trustee and any Paying Agent. Neither the
Trustee nor any Paying Agent shall be responsible for any such calculation. At
the request of the Holder hereof the Calculation Agent will provide to the
Holder hereof the interest rate hereon then in effect and, if determined, the
interest rate which will become effective as of the next Interest Reset Date.

         4.   Unless indicated on the face hereof that this Note is a Global
Security, payments of interest (other than interest payable at the Maturity
Date) will be made by mailing a check to the Holder at the address of the Holder
appearing on the Securities Register on the applicable Record Date or by wire
transfer of immediately available funds, but only if appropriate payment
instructions have been received in writing by the Company's Paying Agent in the
City of Detroit not less that 15 days prior to the applicable Interest Payment
Date. Unless indicated on the face hereof that this Note is a Global Security,
principal and any premium and interest payable at the Maturity Date will be paid
in immediately available funds upon surrender of such Note at the office of a
Paying Agent in the City of Detroit or at such other office or agency as the
Company may designate. If indicated on the face hereof that this Note is a
Global Security, the principal hereof and any premium and interest due on any
Interest Payment Date or at the Maturity Date will be made available to the
Trustee on such date. As soon as possible thereafter, the Trustee will make such
payments to the Depositary in immediately available funds in accordance with
existing arrangements between the Trustee and the Depositary.

         5.   Unless otherwise specified on the face hereof, the Notes will not
be subject to any sinking fund. The Notes will be redeemable at the option of
the Company prior to the Stated Maturity only if an Initial Redemption Date is
specified on the face hereof. If so specified, the Notes will be subject to
redemption at the option of the Company on any date on and after the applicable
Initial Redemption Date in whole or from time to time in part in increments of
$1,000 or the minimum denomination specified on the face hereof (provided that
any remaining principal amount thereof shall be at least $1,000 or such minimum




                                       16


<PAGE>   17


denomination), at the applicable Redemption Price (as defined below) on notice
given not more than 45 nor less than 30 days prior to the date of redemption and
in accordance with the provisions of the Indenture. "Redemption Price", with
respect to an Note, means an amount equal to the sum of (i) the Initial
Redemption Percentage specified on the face hereof (as adjusted by the Annual
Redemption Percentage Reduction, if applicable) multiplied by the unpaid
principal amount of the portion to be redeemed plus (ii) accrued interest to the
date of redemption. The Initial Redemption Percentage, if any, applicable to a
Note shall decline at each anniversary of the Initial Redemption Date by an
amount equal to the applicable Annual Redemption Percentage Reduction, if any,
until the Redemption Price is equal to 100% of the unpaid principal amount
thereof or the portion thereof to be redeemed.

        6.    If so specified on the face hereof, the Notes will be repayable by
the Company in whole or in part at the option of the Holders thereof on their
respective Optional Repayment Dates specified on the face hereof. If no Optional
Repayment Date is specified with respect to a Note, such Note will not be
repayable at the option of the Holder thereof prior to Stated Maturity. Any
repayment in part will be in increments of $1,000 or the minimum denomination
specified on the face hereof (provided that any remaining principal amount
thereof shall be at least $1,000 or such minimum denomination). Unless otherwise
specified on the face hereof, the repayment price for any Note to be repaid
means an amount equal to the sum of (i) 100% of the unpaid principal amount
thereof or the portion thereof plus (ii) accrued interest to the date of
repayment. For any Note to be repaid, such Note must be received, together with
the form thereon entitled "Option to Elect Repayment" duly completed, by the
Trustee at its Corporate Trust Office (or such other address of which the
Company shall from time to time notify the Holders) not more than 60 nor less
than 30 days prior to the date of repayment. Exercise of such repayment option
by the Holder will be irrevocable.

              If indicated on the face hereof that this Note is a Global
Security, the option for repayment may be exercised by the applicable
Participant that has an account with the Depositary, on behalf of the Holder of
any beneficial interest in this Note, by delivering a written notice
substantially similar to the above mentioned form to the Trustee at its
Corporate Trust Office (or such other address of which the Company shall from
time to time notify the Holders), not more than 60 nor less than 30 days prior
to the date of repayment. A notice of election from the applicable Participants
on behalf of the Holder of any beneficial interest in this Note, to exercise its
option to have such Note repaid must be received by the Trustee by 5:00 p.m.,
New York City time, on the last day for giving such notice. In order to ensure
that notice is received by the Trustee on a particular day, the Holder of any
beneficial interest in this Note, must so direct the applicable




                                       17

<PAGE>   18


Participant before such Participant's deadline for accepting instructions for
that day. Different firms may have different deadlines for accepting
instructions from their customers. Accordingly, the Holder of any beneficial
interest in this Note should consult the Participant through which it owns its
interest therein for the respective deadlines for such Participant. All notices
shall be executed by a duly authorized officer of such Participant (with
signature guaranteed) and shall be irrevocable. In addition, the Holder of any
beneficial interest in this Note, shall effect delivery at the time such notice
of election is given to the Depositary by causing the applicable Participant to
transfer such Holder's interest in this Note on the Depositary's records, to the
Trustee.

         7.   If an Event of Default with respect to the Notes shall occur and
be continuing, the principal of all of the Notes may be declared due and payable
in the manner and with the effect provided in the Indenture. If the principal of
any Original Issue Discount Note is declared to be due and payable as described
in the Indenture, the amount of principal due and payable with respect to such
Note shall be limited to the sum of the aggregate stated principal amount of
such Note multiplied by the Issue Price (expressed as a percentage of the
aggregate principal amount) indicated on the face hereof plus the original issue
discount accrued from the Original Issue Date indicated on the face hereof to
the date of declaration, which accrual shall be calculated using the "interest
method" (computed in accordance with generally accepted accounting principles)
in effect on the date of declaration. An Original Issue Discount Note is a Note
that has a stated redemption price at its maturity that exceeds its Issue Price
by an amount equal to or greater than a de minimis amount (0.25% of the stated
redemption price at maturity multiplied by the number of complete years to the
Stated Maturity for such Note) and any other Note designated by the Company as
issued with original discount.

         8.   The Indenture may be modified by the Company and the Trustee
without consent of any Holder with respect to certain matters as described in
the Indenture. In addition, the Indenture permits, with certain exceptions as
therein provided, the amendment thereof and the modification of the rights and
obligations of the Company and MCN Energy Group Inc. ("MCN") and the rights of
the Holders of the Securities of each series to be affected under the Indenture
at any time by the Company, MCN and the Trustee with the consent of the Holders
of a majority in principal amount of the Securities at the time Outstanding of
each series to be affected. The Indenture also contains provisions permitting
the Holders of a majority in principal amount of the Securities of each series
at the time Outstanding, on behalf of the Holders of all Securities of such
series, to waive compliance by the Company or MCN with certain provisions of the
Indenture and certain past defaults under the Indenture and




                                       18


<PAGE>   19


their consequences. Any such consent or waiver by the Holder of this Note shall
bind such Holder and all future Holders of this Note and of any Note issued upon
the registration of transfer hereof or in exchange hereof or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Note.

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

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

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

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

         12.  Unless otherwise defined herein, all terms used in this Note which
are defined in the Indenture shall have the meanings assigned to them in the
Indenture.



                                       19

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

         14.  If indicated on the face hereof that this Note is a Global
Security, no holder of any beneficial interest in this Note held on its behalf
by a Depositary or a nominee of such Depositary shall have any rights under the
Indenture with respect to such Global Security, and such Depositary or nominee
may be treated by the Company, the Trustee, and any agent of the Company or the
Trustee as the owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall impair, as between a
Depositary and such holders of beneficial interests, the operation of customary
practices governing the exercise of the rights of the Depositary as holder of
any Security.

         15.  If not indicated on the face hereof that this Note is a Global
Security, this Note is exchangeable for a like aggregate principal amount of
Notes of a different authorized denomination, as requested by the Holder
surrendering the same, as provided in the Indenture and subject to certain
limitations therein set forth. If indicated on the face hereof that this Note is
a Global Security, it is exchangeable in whole but not in part, for Notes
registered in the names of Persons other than the Depositary or its nominee or
in the name of a successor to the depositary or a nominee of such successor
depositary only if (i) the Depositary notifies the Company that it is unwilling
or unable to continue as Depositary for this Note or if at any time such
Depositary shall no longer be eligible or in good standing under the Securities
Exchange Act of 1934, as amended, or other applicable statute or regulation,
and, in either case, a successor depositary is not appointed by the Company, or
(ii) the Company in its discretion at any time determines not to have all of the
Notes represented by one or more Global Security or Securities. If this Note is
exchangeable pursuant to the preceding sentence, it shall be exchangeable for
Notes of like tenor and terms in definitive form in aggregate principal amount
equal to the principal amount of the Global Security. Subject to the foregoing,
if this Note is a Global Security it is not exchangeable, except for a Note or
Notes of the same aggregate denominations to be registered in the name of such
depositary or its nominee or in the name of a successor to the Depositary or a
nominee of such successor depositary.
