                              FUNDING OF BENEFITS


     4.01.  Unfunded Plan.  The Plan shall be unfunded.  All benefits payable
under the Plan shall be paid from the Company's general assets.  The Company
shall not be required to set aside or hold in trust any funds for the benefit
of a Participant or Beneficiary, who shall have the status of a general
unsecured creditor with respect to the Company's obligation to make benefit
payments pursuant to the Plan.  Any assets of the Company available to pay Plan
benefits shall be subject to the claims of the Company's general creditors and
may be used by the Company in its sole discretion for any purpose.

     4.02.  Dividend Equivalents.  Dividend equivalents equal to 50% of the
dividends payable on MCN Common Stock shall be credited to a Participant's
Account during the Deferral Period based on the number of shares of Company
common stock deemed to be held in such Participant's Account.  A Participant
may elect on his Deferral Form to have 0%, 50% or 100% of such credited
dividend equivalents paid directly to him in cash during the Plan Year.  A
Participant's election regarding credited dividend equivalents shall be
effective on the January 1 immediately following execution of his Deferral Form
and shall remain in effect until revoked by the Participant.  Revocation of a 
dividend equivalent election shall be effective on the January 1 immediately

                                   SECTION 5

                           FORM AND TIMING OF PAYMENT


     5.01. Form and Timing of Payment.  After completion of his Deferral
Period, a Participant shall be entitled to a distribution of his Account on the
first of the month following the month in which his Deferral Period ends.
Notwithstanding the fact that a  Participant's Account will be valued on a cash
basis after completion of the Deferral Period in accordance with Section 3.06,
the distribution to a Participant shall be paid in Company common stock  equal
to the number of shares of Company common stock deemed to be held in the
Participant's Account and valued at the closing price of MCN Corporation common
stock on the New York Stock Exchange Composite Tape on the day before payment
is made.  The distribution of Company common stock shall be made in accordance
with the Participant's selection on his Deferral Form; either in equal monthly
payments over a period not less than one year and not more than 15 years, in
one year increments, or as a lump sum distribution of the Participant's
Account.  The  number of shares distributed monthly shall be calculated to pay
out over the specified period the entire balance in the Participant's Account
as of the end of the Deferral Period with interest credited monthly on the
declining balance at the Plan Interest Rate.  The number of shares distributed
monthly to the Participant shall be adjusted on January 1 of each year to
reflect changes in the Plan Interest Rate and other changes to the
Participant's Account balance.

     5.02. Change in Payment Option. The payment option selected by the
Participant on his Deferral Form may be changed at any time by the Participant
by submitting a new payment selection to the Committee, but a change shall be
effective only if it is received by the Committee at least 36 months before
payments under the Plan commence.

     5.03. Hardship Withdrawal Benefits.  At any time prior to a distribution
in accordance with Section 5.01, a Participant may request that the Committee
make a distribution to him of all or part of his Account within 120 days.  Such
distribution shall be made only if the Committee determines that the
Participant is suffering from a financial hardship that cannot be satisfied
from his normal sources of income, and the distribution shall be limited to the
amount required to meet the financial hardship.  In making these
determinations, the Committee shall utilize the regulations proposed or adopted
by the U.S. Department of Treasury pursuant to Section 401(k) of the Code and
the rules under the Savings Plan.  A financial hardship shall be satisfied from
the Plan to the extent possible then from the MCN Executive Deferred
Compensation Plan, the Supplemental Savings Plan, and finally from the Savings
Plan.

     6.01. Beneficiary Designation. A Participant shall designate a Beneficiary
on his Beneficiary Designation Form, as provided in Exhibit B.  The designation
of a Beneficiary other than the Participant's Spouse must be consented to in
writing by the Spouse.  If a Participant has not designated a Beneficiary, or
if a designated Beneficiary is not living or in existence at the time of a

                    ADDITIONAL PROVISIONS AFFECTING BENEFITS


     8.01. Tax Withholding.  Benefit payments hereunder shall be subject to
applicable federal, state or local tax withholding laws. A Participant shall be
responsible for making payment to MCN Corporation or a participating Affiliated
Company, as appropriate, in an amount equal to the income payroll tax
withholdings on the fair market value of the payments made in accordance with
Section 5.01.  A Participant may sell up to 50 percent of a distribution made
under Section 5.01 on the open market to facilitate payment of the tax
withholdings.  In no circumstance will the Company purchase or otherwise issue
cash for any stock distributed under this Plan.

     8.02. Dilution and Other Adjustments.  In the event of any change in the
outstanding shares of Company common stock by reason of any stock dividend,
stock split, recapitalization, merger, consolidation, spin-off, reorganization,
combination or exchange of shares or other similar corporate change, the
Committee, in its sole discretion, shall make the appropriate adjustment in
each Participant's Account.  If any such adjustment shall result in a
fractional share, such fraction shall be disregarded.  Such adjustments made by
the Committee shall be conclusive and binding for all purposes of the Plan.



                                   SECTION 9

                           ADMINISTRATION OF THE PLAN


     9.01. Duties and Power. The Committee shall be responsible for the
general administration of the Plan and the proper execution of its provisions. 
It shall also be responsible for the interpretation of the Plan and the
determination of all questions arising thereunder.  It shall maintain all
necessary books of accounts and records.  It shall have power to establish,
interpret, enforce, amend, and revoke, from time to time, such rules and
regulations for the administration of the Plan and the conduct of its business
as it deems appropriate, including the right to remedy ambiguities,
inconsistencies and omissions (provided such rules and regulations are
uniformly applied to all persons similarly situated).  Any action that the
Committee is required or authorized to take shall be final and binding upon
each and every person who is or may become a Plan Participant or Beneficiary. 
The Committee may amend this Plan to comply with changes to the Code, so long
as the amendment does not materially increase the cost of maintaining the Plan
or decrease benefits to Participants or Beneficiaries.

     9.02. Benefit Statements.  No later than 120 days after the end of each
Plan Year, the Committee will provide each Participant with a statement setting
forth the Participant's Account balance as of the last day of the immediately
preceding Plan Year.


                                   SECTION 10

                     AMENDMENT, SUSPENSION, AND TERMINATION


     10.01. Right to Amend or Terminate.  The Plan may be amended or terminated
by the Board of Directors at any time.  Such amendment or termination may
modify or eliminate any benefit hereunder except that such amendment or
termination shall not affect the rights of Participants or Beneficiaries to the
vested portion of a Participant's Account as of the date of such amendment or
termination.

     10.02. Right to Suspend.  If the Board of Directors determines that
payments under the Plan would have a materially adverse affect on the Company's
ability to carry on its business, the Board of Directors may suspend such
payments temporarily for such time as in it sole discretion it deems advisable,
but in no event for a period in excess of one year.  During the period of
suspension, the payment of dividend equivalents shall continue to be made in
cash to the Participant in accordance with Section 5.01. The Company shall pay
such suspended payments in a lump sum distribution of Company common stock
immediately upon the expiration of the period of suspension.

     10.03. Non-ERISA Plan.  The Plan is intended to provide benefits for "a
select group of management or highly compensated employees" within the meaning
of Sections 201, 301 and 401 of ERISA, and therefore to be exempt from Sections
2, 3 and 4 of Title 1 of ERISA.  Accordingly, the Plan shall terminate and,
existing Account balances and other benefits In Pay Status shall be paid in a
single, actuarially equivalent lump-sum and no further benefits, vested or
non-vested, shall be paid hereunder in the event it is determined by a court of
competent jurisdiction or by an opinion of counsel that the Plan constitutes an
employee pension benefit plan within the meaning of Section 3(2) of ERISA which
is not so exempt.

     10.04. Right to Accelerate.  The Board of Directors in its sole discretion
may accelerate all vested benefits upon termination of the Plan, and pay such
benefits in a single, actuarially equivalent lump-sum distribution of Company
stock.

                                 MISCELLANEOUS


     11.01 Right to Continued Employment.  Nothing in the Plan shall create or
be construed as a contract between the Company and employees for any matter
including giving any person employed by the Company the right to be retained in
the Company's employ.  The Company expressly reserves the right to dismiss any
person at any time, with or without cause, without liability for the effect
that such dismissal might have upon him as a Participant in the Plan.

     11.02. Prohibition Against Alienation.  Except as otherwise provided in
the Plan, no right or benefit under the Plan shall be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or
charge, and any attempt to so anticipate, alienate, sell, transfer, assign,
pledge, encumber, or charge the same shall be void.  No such right or benefit
shall be liable for or subject to the debts, contracts, liabilities,
engagements, or torts of the person entitled to such right or benefit.

     11.03. Sayings Clause.  If any provision of this Plan is held by a court
of competent jurisdiction to be invalid or unenforceable, such invalidity or
unenforceability shall not affect any other provision and the remaining
provisions hereof shall continue to be construed and enforced as if the invalid
or unenforceable provision had not been included.

     11.04. Payment of Benefit of Incompetent.  In the event the Committee
finds that a Participant, former Participant, or Beneficiary is unable to care
for his affairs because of his minority, illness, accident, or other reason,
any benefits payable hereunder may, unless other claim has been made therefor
by a duly appointed guardian, committee or other legal representative, be paid
to a spouse, child, parent, or other blood relative or dependent or to any
person found by the Committee to have incurred expenses for the support and
maintenance of such Participant, former Participant, or Beneficiary; and any
such payments so made shall be a complete discharge of all liability therefor.

     11.05. Spouse's Interest.  The interest in the benefits hereunder of a
Spouse who has predeceased the Participant shall automatically pass to the
Participant and shall not be transferable by such Spouse in any manner
including but not limited to such Spouse's will, nor shall such interest pass
under the laws of intestate succession.

     11.06. Successors.  In the event of any consolidation, merger, acquisition
or reorganization of the Company, the obligations of the Company under this
Plan shall continue and be binding upon the Company and its successors.

     11.07. Gender, Number and Heading.  Whenever any words are used herein in
the masculine gender, they shall be construed as though they were also used in
the feminine gender in all cases where they would so apply.  Whenever any words
used herein are in the singular form, they shall be construed as though they

convenience and reference and constitute no part of the Plan.

     11.08. Legal Fees and Expenses.  The Company shall pay all legal fees and
expenses that a Participant may incur as a result of the Company contesting the
validity, enforceability, or the Participant's interpretation of, or
determinations under this Plan, other than Section 5.03.

     11.09. Choice of Law.  This Plan shall be governed by and construed in
accordance with the laws of the State of Michigan to the extent not superseded
by applicable federal statues or regulations.

     11.10. Affiliated Employees.  Transfers of employment between Affiliated
Companies and the Company or other Affiliated Companies will be treated as

                                   SECTION 12

                          CHANGE IN CONTROL PROVISIONS


     12.01. General.  In the event of a Change in Control, as defined in
Section 12.04, then notwithstanding any other provision of the Plan, the
provisions of this Section 12 shall be applicable and shall supersede any
conflicting provisions of the Plan.

     12.02. Transfer to Rabbi Trust.  The Company has established a trust
pursuant to a Trust Agreement dated January 3, 1991 (the "Rabbi Trust").  The
terms of the Rabbi trust provide that, in the event of a Change in Control and
thereafter, assets are to be transferred to such trust to provide benefits
under the Plan.  The Company shall make all transfers of funds required by such
Rabbi trust in a timely manner and shall otherwise abide by the terms of such
Rabbi trust.

     12.03. Joint and Several Liability.  Upon and at all times after a Change
in Control, the liability under the Plan of the Company and each Affiliated
Company that has adopted the Plan shall be joint and several so that the
Company and each such Affiliated Company shall each be liable for all
obligations under the Plan to each employee covered by the Plan, regardless of
the corporation by which such employee is employed.
