                                PROXY STATEMENT
 
GENERAL INFORMATION
 
     The Board of Directors of MCN Corporation (the MCN Board) solicits your
proxy for use at the Annual Meeting of Shareholders of MCN Corporation (MCN or
the Company) to be held on Thursday, April 28, 1994 at 1:00 p.m., and at any
adjournments.
 
VOTING
 
     As of March 1, 1994, the record date for determination of shareholders
entitled to notice of and to vote at the Annual Meeting, there were 29,XXX,XXX
outstanding shares of MCN common stock, $.01 par value (MCN Common Stock). Each
outstanding share is entitled to one vote on all matters which may come before
the Annual Meeting.
 
     Michigan law and the Company's bylaws require the presence of a quorum for
the annual meeting, defined here as a majority of the votes entitled to be cast
at the meeting. Votes withheld from director nominees and abstentions will be
counted in determining whether a quorum has been reached.
 
     Assuming a quorum has been reached, a determination must be made as to the
results of the vote on each matter submitted for shareholders approval. The
director nominees must receive a plurality of the votes cast at the meeting,
therefore abstentions will not affect the election of directors. The
ratification of the Company's Non-Officer Director Stock Award Plan must be
approved by a majority of votes present, or represented and entitled to vote at
the meeting, therefore abstentions will have the same legal effect as votes
against the matter. The approval of the amendment of the Company's Articles of
Incorporation to increase the number of authorized shares of MCN Common Stock
must be approved by a majority of the votes outstanding and not merely the votes
cast, therefore abstentions will have the same legal effect as votes against the
matter. The selection of the Company's auditors must be approved by a majority
of the votes cast at the meeting, therefore abstentions will not affect the
selection of the Company's auditors.
 
     Under the rules of the New York Stock Exchange (NYSE), brokers who hold
shares on behalf of their customers (shares held in street name), have the
authority to vote on certain items when they have not received instructions from
beneficial owners. However, brokers are not authorized to vote on "non-routine"
matters if they do not receive instructions from beneficial owners (Broker
Non-votes). Under NYSE rules, all the matters presently before the meeting are
"routine" matters, therefore brokers holding shares in street name for their
customers may vote, in their discretion, on behalf of any customer who does not
furnish voting instructions. If a "non-routine" matter comes before the meeting,
Broker Non-votes will not be treated as votes cast in determining the outcome of
the vote.
 
     All shares represented by signed Proxies, which are received at or prior to
the meeting will be voted at the Annual Meeting. A Proxy may be revoked at any
time before it is exercised by notifying the Secretary of MCN in writing before
the Proxy is exercised, or by delivering to the Secretary of MCN a Proxy bearing
a later date, or by attending the Annual Meeting and voting in person.

                      PROPOSAL 1 -- ELECTION OF DIRECTORS
 
     The MCN Board consists of ten members divided into three classes, with the
term of each director expiring at the Annual Meeting of MCN in the year
indicated below. Generally, one-third of the MCN Board is elected each year.
 
     Unless otherwise instructed on the Proxy, the proxy holders intend to vote
for the election of Alfred R. Glancy III, Frank M. Hennessey and Howard F. Sims
to three-year terms as directors. Each of the nominees is a current member of
the MCN Board. The MCN Board believes that, if elected, each nominee will be
able and willing to serve. However, if any nominee should be unable or unwilling
to serve as a director, the MCN Board may select a substitute nominee and, in
that event, the Proxy will be voted for the person so selected. The remaining
seven directors will continue to serve in accordance with their previous
elections.
 
     Information concerning the three directors nominated for a term of three
years, and the seven continuing MCN Board members, is set forth below.

MEETINGS AND COMMITTEES OF THE MCN BOARD
 
     The MCN Board of Directors held eight regular meetings during 1993 and also
served on standing committees of the Board. The directors attended an average of
95% of all meetings of the Board and Committees on which they served. A majority
of directors attended all meetings of the Board. The MCN Board has the following
standing committees.
 
     AUDIT COMMITTEE -- The Audit Committee, which held three meetings during
1993, recommends to the MCN Board the selection of independent auditors; reviews
the scope of audit procedures and the results of the respective audits and
recommendations to management; reviews auditors' fees, annual financial
statements, adequacy of internal audit procedures and results of those
procedures; and reviews MCN's policies relating to business conduct.
 
     COMPENSATION COMMITTEE -- The Compensation Committee held two meetings
during 1993. Subject to MCN Board approval, the Compensation Committee
establishes the salaries and other direct compensation for officers of MCN,
Michigan Consolidated Gas Company (MichCon) and MCN Investment Corporation
(MCNIC); and reviews and makes recommendations regarding the salary policies for
other officers, management and supervisory personnel.

     FINANCE COMMITTEE -- The Finance Committee held two meetings during 1993.
The Finance Committee reviews and consults with management and makes
recommendations to the MCN Board regarding the financial affairs of MCN and its
subsidiaries, including the review of financial plans, recommendations regarding
the timing and amount of securities to be issued, and investment policies of the
trusteed benefit plans and other corporate funds.
 
     CORPORATE RESPONSIBILITY COMMITTEE -- The Corporate Responsibility
Committee, which held two meetings during 1993, consults with management
regarding corporate contributions and contributions from the MichCon Foundation,
reviews and recommends to the MCN Board an annual corporate contribution budget,
and conceives and recommends programs to assure that MCN and its subsidiaries
carry out their respective corporate responsibilities in an effective and
efficient manner.
 
DIRECTORS' COMPENSATION
 
     Officers of MCN or its subsidiaries who serve on the MCN Board do not
receive any additional compensation for service as directors. However, directors
of MCN who are not employees of MCN receive an annual fee of $18,000. Such
directors are also paid a fee of $750 for attendance at each MCN Board and
committee meeting. Directors are eligible to participate in a plan which
provides for deferral of all or part of their annual fee, with interest accrued
on amounts deferred. The deferral plan also includes a pre-retirement survivor
benefit which provides the participant's beneficiary with a payment equal to the
present value of any deferrals that would have been made prior to normal
retirement. In addition, based upon shareholder passage of Proposal 2, MCN's
outside directors will continue to receive 100 shares of MCN Common Stock
annually. (See Proposal 2 on page 19 for details.) It is anticipated that future
increases in Non-officer Director compensation will be primarily through
additional shares of MCN Common Stock.
 
     Non-officer Directors also participate in the Supplemental Death Benefit
and Retirement Income Plan. Under the plan, if a Non-officer Director dies while
in office, the director's surviving spouse is entitled to a lump-sum payment of
$100,000. This plan also provides that in the event a Non-officer Director holds
office until reaching age 65 or older and thereafter ceases to hold office,
otherwise than by death, the director can elect to receive either (i) a
supplemental retirement benefit of $10,000 annually for each of the ten years
following the date the director ceased to hold office, or (ii) a post-retirement
death benefit of $100,000 payable solely to the director's surviving spouse upon
the director's death.

Each performance unit is equivalent to a share of MCN Common Stock. The
performance units initially granted are based on MCN's total shareholder return
for the previous three years compared to the total shareholder return for a
group of peer companies over the same period. Once initially granted, regular
dividend equivalents are paid on those performance units. The initial grants are
adjusted upward or downward after a three year period based on MCN's total
shareholder return for this subsequent period compared to the total shareholder
return for a group of peer companies over the same period. The final grant,
which is expected to be paid 50% in cash and 50% in MCN Common Stock, will range
from zero to 200% of the initial grant and the stock must be held, except for
extraordinary circumstances, until the recipient retires, dies or otherwise
terminates employment.

(1) In order to encourage executives to maintain their holdings in shares
    purchased under the Stock Option Plan, the Company provides loans at an
    interest rate in accordance with IRS guidelines based on the market yield of
    U.S. short-term marketable securities. Pursuant to this provision, Mr.
    Glancy initiated a loan in 1991, at an interest rate of 6.57% which was
    refinanced during 1992 in conjunction with the exercise of additional stock
    options by Mr. Glancy. The new loan, at the then current interest rate of
    4.43%, covered a maximum of $1,250,708, including interest, during 1993. A
    balance of $1,151,919, including interest, was outstanding as of December
    31, 1993. The loan is secured by 84,814 shares of MCN Common Stock with a
    year-end market value of $2,947,287.
 
CHANGE OF CONTROL EMPLOYMENT AGREEMENTS
 
     MCN entered into Change of Control Employment Agreements with its five
named executive officers during 1990. The agreements generally have a term of
three years beginning with the change of control, obligate the officer to
continue to serve MCN in the officer's then current capacity, and require MCN to
compensate the officer in an amount at least equal to the officer's base salary
plus the average annual bonus paid to the officer during the preceding three
years and provides for the vesting of various unfunded benefits. The agreements
also provide for the grossed-up payment of any Federal excise taxes due from the
executive as a result of any payments received under the agreement and provide
three years of continued participation in MCN's benefit and retirement programs.
MCN's obligations to the officer, including the obligation to pay base salary
and any bonuses, can only be extinguished if the officer's employment is
terminated by MCN for "good cause," by the officer without "good reason," both
as defined in the agreements, or by death or disability.

     RETIREMENT PLANS. All salaried employees of MCN and certain of its
subsidiaries (the Participating Companies) participate in a noncontributory,
defined benefit retirement plan (the Retirement Plan). Under the Retirement
Plan, the monthly pension at normal retirement (age 65) is calculated using a
formula providing a single life monthly benefit equal to (a) 1.33% of final
average monthly earnings multiplied by the number of total years of credited
service with the Participating Companies; plus (b) 0.5% of final average monthly
earnings which exceed a 35 year average social security wage base multiplied by
the number of years of credited service up to 35 years. Early retirement
benefits (at a reduced benefit if such retirement is before the participant
attains age 62) are permitted under the plan on or after the date a participant
attains age 55, if the participant's age plus years of credited service (as
defined in the plan), equals or exceeds 70. An employee's final average monthly
earnings is defined as his or her highest average monthly earnings for a
consecutive 60-month period during the participant's last 15 years of
employment. An employee is not vested under the Retirement Plan until he or she
has completed five years of credited service or has attained age 65.
 
     A Nonqualified Retirement Plan is also maintained which provides for the
payment of benefits that would otherwise be payable under the Retirement Plan
but for limitations imposed by Federal tax law on benefits paid by qualified
plans.
 
     The table above illustrates the total estimated annual normal retirement
pension benefits including the Nonqualified Retirement Plan amounts, if
applicable, that will be payable upon normal retirement at age 65 to
participants for the specified remuneration and years of credited service
classifications. The table does not reflect any reductions in retirement
benefits that would result from the selection of one of various available
survivorship options or the election to retire prior to age 65. Benefit amounts
are computed on a straight life annuity basis.
 
     As of December 31, 1993, the credited years of service (rounded to the
nearest whole year) for each of the individuals detailed under "Executive
Compensation" on page 9, are as follows: Mr. Glancy, 31 years; Mr. Ewing, 22
years; Mr. McCrackin, 38 years; Mr. Scullion, 38 years and Mr. Schiffer, 17
years.

     SUPPLEMENTAL DEATH BENEFIT AND RETIREMENT INCOME PLAN. The Company's
executive officers and certain other officers of the Participating Companies
currently participate in a Supplemental Death Benefit and Retirement Income
Plan. Under this plan, the pre-retirement death benefits payable to an
employee's surviving spouse, are 50% of the employee's final salary until such
time as the employee would have reached age 65; thereafter, payments are 20% of
salary until the employee would have reached age 75. At retirement an employee
may elect to receive (i) annual supplemental retirement income equal to 20% of
the employee's final annual salary payable for a period of ten years after age
62; or (ii) other available post retirement benefits which are actuarially
equivalent to the ten-year payment option.
 
COMPENSATION COMMITTEE INTERLOCKS
AND INSIDER PARTICIPATION
 
     Mr. Thomas H. Jeffs II serves on the Compensation Committee of MCN. Mr.
Jeffs is an executive officer of NBD Bancorp and its principal subsidiary, NBD
Bank, N.A. Mr. Alfred R. Glancy III, Chairman, President and Chief Executive
Officer of MCN, serves as a Director of NBD Bancorp and NBD Bank, N.A.
 
     The MCN Board of Directors passed a resolution in December 1992 prohibiting
an officer-director of MCN from serving on the Compensation Committee of an
unaffiliated corporation if an officer-director of the unaffiliated corporation
serves on the MCN Compensation Committee. Also, no director of MCN can serve on
the MCN Compensation Committee if he or she is an officer-director of an
unaffiliated corporation on whose Compensation Committee one or more officer-
directors of MCN serve. Mr. Jeffs' service on the MCN Compensation Committee and
Mr. Glancy's service as a Director of NBD Bancorp and NBD Bank, N.A. are
consistent with the MCN resolution.

REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE
COMPENSATION.
 
     The Compensation Committee (the Committee) establishes MCN's strategic
compensation objectives. The Committee then monitors and evaluates the design
and effectiveness of MCN's executive pay programs against those objectives. For
1993, under Committee review, MCN's executive compensation programs were
redesigned to more explicitly link executive pay with MCN's strategic direction
and Company objectives. Following is a summary of MCN's current executive
compensation objectives:
 
OBJECTIVES & METHODOLOGY:
 
     The primary and overriding objective is to provide a total compensation
package that allows MCN to attract, retain and motivate executive employees. In
doing so,
 
      - MCN establishes total compensation opportunity (base salary plus annual
        incentive and long-term incentive) at competitive levels. The
        methodology used to determine market competitiveness is an annual survey
        of MCN's peer companies(1) as well as analysis of national and industry
        executive compensation data.
 
           - Base salary levels are generally set between the 40th and 65th
             percentile relative to peer companies.
 
           - Total compensation opportunity can exceed that of peer companies
             (90th percentile or greater) when MCN performance warrants.
 
      - Performance, both Company and individual, drive total compensation
        levels.
 
           - Overall executive effectiveness, assessed against a set of
             objectives, determines base pay increases.
 
           - Annual incentives relate to attaining financial, operating, and
             individual objectives.
 
           - Long-term incentives relate to creating shareholder value.
 
      - Variable (incentive) compensation opportunity is set at levels to put a
        significant percentage of executive compensation at risk, thus linking
        executive and shareholder interests. Current programs put approximately
        50% of CEO compensation at-risk.
 
      - Program design encourages and increases stock ownership by executives to
        better align their interests with those of shareholders. Currently, any
        awards under the long-term incentive plan are paid out 50% in stock with
        a requirement, except for extraordinary circumstances, that the
        executive retain ownership while actively employed by the Company or any
        of its affiliates.

      - All components of executive compensation programs are communicated to
        participating executives to insure they understand the opportunity (and
        the risks) available based on performance, thus increasing the
        motivational impact of the plans.
 
ROLE OF THE COMMITTEE:
 
     Specifically, the Committee makes recommendations to the Board of Directors
on the compensation levels of all officers of MCN, MCNIC and MichCon, and
reviews the recommendations for base pay, annual incentive awards and long-term
incentive awards for the other executives of the Company. In addition, the
Committee has oversight responsibility for all the Company's compensation
programs to ensure that they are aligned with the mission and objectives of the
Company.
 
     In fulfilling these responsibilities, the Committee utilizes the internal
compensation function or outside consultants to:
 
      - Research and summarize pay and incentive practices of peer companies and
        industry averages.
 
      - Develop and recommend annual merit program and long and short-term
        incentive award parameters.
 
     In 1993, the Committee did not utilize outside compensation consultants.
 
SPECIFIC DISCUSSION ON THE COMPONENTS OF EXECUTIVE COMPENSATION:
 
     The components of an MCN executive's direct compensation consist of base
salary, annual incentives and long-term incentives. These are discussed below:
 
          BASE SALARY -- The base salary of an executive is established when
     entering the position, based on the individual's experience, internal
     equity and external market comparison. Thereafter, increases to base salary
     are determined by the executive's individual performance assessed against a
     set of objectives. Emphasis is on demonstrating corporate strategic
     leadership in attaining business objectives and on a visible commitment to
     the Company's Visions & Values. Increases to base salary are made within
     the same guidelines of the merit program in effect for all nonunion
     employees.
 
          Base salary for the CEO, Mr. Alfred R. Glancy III, and other
     executives are reviewed annually based on an assessment of Company
     performance, individual performance, salary position relative to the
     external market, the Company's internal merit program and MCN's stated
     compensation objectives on base salary. In February 1994, the Committee
     determined [information to follow]
 
          INCENTIVE AWARDS -- Incentive Awards are based on Company performance
     results compared to internal financial and operational performance targets,
     and the financial performance of peer companies. Incentive Awards are
     comprised of Annual Incentives and Long-Term Incentives, which are
     discussed below.
 
             ANNUAL INCENTIVES ("THE ANNUAL MANAGEMENT PERFORMANCE PLAN") --
        Payout under the Company's annual incentive plan is based on the
        performance of the Company and the
 
                                       15
<PAGE>   19
 
        individual executive's performance, as measured against goals
        established by the Committee prior to the start of the fiscal year.
 
             In 1993, the measures of Company performance used to determine
        annual incentive awards were as follows:
 
             - for MichCon executives, the achievement of combined financial and
        operating goals. Specifically for 1993:
 
              Authorized rate of return (AROR) -- weighted 70%
 
              Customer Satisfaction -- weighted 10% (measured through
              point-of-service survey)
 
              Employee Satisfaction -- weighted 10% (measured through an annual
              employee survey)
 
              Safety -- weighted 10% (measured by number of lost work days)
 
             - for MCN Investment Corporation (MCNIC), the achievement of a net
        income goal.
 
             - for MCN executives, the weighted combination of MichCon and MCNIC
        results. Weighting is determined annually by the Committee prior to the
        start of the fiscal year. For 1993, the weighting was 80% MichCon and
        20% MCNIC.
 
             In 1993, the standard award opportunity for the CEO was 35% of base
        salary. Standard awards for the xx other eligible executives ranged from
        15% to 30%. The actual award could exceed or be less than the standard
        award depending on the achievement of the Company performance measures
        discussed above. Payout of any portion of the award is based on
        individual performance.
 
             MichCon's performance in 1993, using the above measures, resulted
        in an annual incentive award fund equal to 112% of the standard payout.
        MCNIC performance in 1993 was 107% of target net income. Combining the
        weighted performance of these two MCN subsidiaries resulted in an MCN
        award fund equal to 111% of the standard payout. For CEO, Alfred R.
        Glancy III, this produced an award of 38.9% of his 1993 base salary.
 
             In 1993, a teamwork incentive program was introduced at MichCon and
        MCN for employees not covered by the executive compensation programs.
        Awards are paid on the basis of both Company and team performance.
 
             LONG-TERM INCENTIVES ("PERFORMANCE UNIT PLAN") -- In late 1992, the
        Company redesigned its long-term incentive program to place a larger
        portion of long-term incentives at-risk, encourage a more strategic
        focus on long-term performance from a shareholder perspective, and
        increase the retention value of the plan.
 
             The new program awards performance units to executives based on
        total shareholder return, as compared to the peer group described
        earlier covering a six-year period. This period is divided into two
        parts. The first three years determines the initial grant of performance
        units. Participants receive dividend equivalents on the performance
        units during the subsequent three-year period. The initial grant is
        adjusted upward or downward based upon performance over that subsequent
        three-year period. The final award, if any, is
 
                                       16

        expected to be paid 50% in cash and 50% in stock that is not
        transferrable, except for extraordinary circumstances, until the
        participant retires, dies or otherwise terminates employment. Both the
        initial grant and the final award are made using the following zero to
        200% scale, based on MCN's performance ranking within its peer group:

             Under the 1992 redesign, the standard award for the CEO is set at
        8,000 shares. The standard awards for 46 other participating executives
        range from 500 to 5,000 shares. This design is extended to meet the
        Company's compensation objectives by providing both risk and reward
        potential tied to competitive performance as measured by total return to
        shareholders.
 
             For the three-year period 1991-1993, MCN's total return to
        shareholders was approximately xx%, which placed the Company at the top
        of its peer group. Using the program guidelines and considering MCN's
        top ranking, the Committee granted awards at xx% of the standard award
        level. For CEO, Alfred R. Glancy III, the Committee granted xx,xxx
        performance units.
 
             These units may be as much as doubled or forfeited completely based
        on how MCN's total shareholder return compared to peer companies for the
        1994-1996 period.
 
CONCLUSION
 
     We believe that MCN's Executive Compensation programs closely align each
executive's total compensation potential with individual and Company performance
and shareholder returns, while providing a balanced compensation mix between
base pay and incentives that is market and performance driven. We believe these
programs allow MCN to attract, retain and motivate executive employees. It is
the Compensation Committee's intent to ensure that these alignments continue
into the future and to review and refine the Company's pay and incentive
programs to reflect this objective.

PROPOSAL 2 -- RATIFICATION OF THE MCN CORPORATION'S NON-OFFICER DIRECTOR STOCK
AWARD PLAN
 
     MCN Corporation has adopted, effective May 6, 1993, subject to ratification
by stockholders, a Non-Officer Director Stock Award Plan (the Plan). The purpose
of the Plan is to enhance MCN's ability to attract and retain the services of
well-qualified directors who are not officers or employees of MCN or any of its
subsidiaries (Non-officer Directors) by providing them with an opportunity to
participate in the growth of MCN and to align their interests with those of
MCN's stockholders. In 1993, each Non-officer Director received a grant of 100
shares of MCN Common Stock. Stockholder approval of the Plan will enable MCN to
remain competitive with a number of companies using stock as a method of
Non-officer Director compensation, and will comply with requirements of
applicable federal securities law.
 
     The full text of the Plan is set forth as Exhibit A to this Proxy
Statement. The following is a summary of the material features of the Plan, and
is qualified in its entirety by reference to the Plan as set forth in Exhibit A.
 
     The operation of the Plan is automatic, and awards are granted pursuant to
the Plan. Following stockholder ratification, on the first business day after
each annual meeting of stockholders, each Non-officer Director who was elected
at the meeting or whose term continued thereafter as a director will be granted
100 shares of MCN Common Stock. The number of shares to be granted annually to
each Non-officer Director may be changed by a majority vote of the MCN Board,
but provided, that any changes in the number of shares granted shall be made no
more often than once in any 12-month period. The shares awarded under the Plan
will be in addition to the Non-officer Director annual retainer fee, meeting
fees, or other compensation payable to each Non-officer Director as a result of
his or her service on MCN's Board of Directors.
 
     The Plan will remain in effect until terminated by action of the MCN Board.
The MCN Board may terminate, amend or modify the Plan at any time and from time
to time; provided, however, such amendments may not be made more than once every
six months, other than to comport with changes in the Internal Revenue Code, the
Employee Retirement Income Security Act or the rules thereunder. In addition,
the MCN Board shall not, without the requisite affirmative approval of
stockholders of MCN, make any amendment which requires stockholder approval
under any applicable law, including Rule 16b-3 under the Securities Exchange Act
of 1934, unless such compliance, if discretionary, is no longer desired. Rule
16b-3 currently requires stockholder approval of amendments which would (i)
materially increase the benefits accruing to participants under the Plan, (ii)
materially increase the number of securities issuable under the Plan, or (iii)
materially modify the requirements as to eligibility for participation in the
Plan.
 
     Shares to be issued under the Plan may be authorized and unissued shares or
authorized and issued shares of MCN Common Stock. Provided, however, that the
number of Shares that may be issued under this Plan subsequent to March 1, 1994
may not exceed 1% of the number of shares issued and outstanding on March 1,
1994.

PROPOSAL 3 -- APPROVAL TO AMEND THE MCN CORPORATION ARTICLES OF INCORPORATION
 
     The Company currently is authorized by its Articles of Incorporation to
issue 50 million shares of MCN Common Stock. As of December 31, 1993, MCN has
issued and outstanding 29,496,363 shares of MCN Common Stock, leaving 20,503,637
shares unissued and reserved for issuance. Approval of Proposal 3 would amend
the Company's Articles of Incorporation by increasing the authorized number of
shares of MCN Common Stock to 100 million and the unissued and reserved shares,
therefore, to 70,503,637. The MCN Board has recommended that the Company's MCN
Common Stock shareholders approve this amendment to the Articles of
Incorporation of the Company, as amended, (the Articles) to effect an increase
in the number of authorized shares of MCN Common Stock to 100 million (the
Increased Shares Proposal). This proposal will be adopted upon receiving the
affirmative vote of a majority of the outstanding shares of MCN Common Stock of
the Company. The text of the Company's Articles, as it is proposed to be
amended, is set forth in Exhibit B to this Proxy Statement.
 
     The Increased Shares Proposal is intended to increase the Company's
flexibility by increasing the number of shares of MCN Common Stock that can be
issued without the necessity for further shareholder approval. The MCN Board
believes that the increased flexibility provided by the amendment will enable
the Company promptly and appropriately to respond to future financing needs,
stock splits and other business opportunities.
 
     For example, although not currently under consideration, the MCN Board from
time to time considers the appropriateness of stock splits on MCN Common Stock.
The ability to split the Company stock is currently restricted by the fact that
presently there are fewer unissued and unreserved shares than outstanding and
reserved shares. In addition, given the number of currently outstanding and
reserved shares and the number of additional shares that might be required to be
issued and reserved, the Company could not effect certain transactions without
obtaining shareholder approval for an increase in the authorized number of
shares of MCN Common Stock. The cost, prior notice requirement and delay
involved in obtaining shareholder approval at the time that a transaction may
become desirable could make it difficult or impossible to effect the
transaction. The additional shares of MCN Common Stock, together with other
authorized and unissued shares, generally would be available for issuance
without any requirement for further shareholder approval, unless shareholder
action is required by applicable law or by the rules of the stock exchange on
which the Company's securities may then be listed.
 
     Although the MCN Board will authorize the issuance of additional shares
only when it considers doing so to be in the best interests of shareholders, the
issuance of additional MCN Common Stock may, among other things, have a dilutive
effect on earnings and equity per share of MCN Common Stock and on the voting
rights of holder of shares of MCN Common Stock.
 
     In addition to the Company's authorization to issue MCN Common Stock, the
Company is also authorized to issue 25 million shares of Preferred Stock, no par
value (Preferred Stock), of which no shares are outstanding.
 
     THE MCN BOARD OF DIRECTORS AND MANAGEMENT RECOMMEND A VOTE FOR THIS
PROPOSAL.

PROPOSAL 4 -- SELECTION OF AUDITORS
 
     The MCN Board has selected Deloitte & Touche as independent auditors to
audit the financial statements of MCN and its subsidiaries for the year ending
December 31, 1994 and is submitting its choice for ratification by shareholders.
Deloitte & Touche, or its predecessor, has served as MCN's auditors since 1988
and MichCon's auditors since 1986. A representative of Deloitte & Touche will be
present at the Annual Meeting of Shareholders and will have an opportunity to
make a statement and respond to appropriate questions. If the appointment is not
ratified, the MCN Board will appoint another firm as the independent auditors
for the year ending December 31, 1994.
 
     THE MCN BOARD OF DIRECTORS RECOMMENDS THE RATIFICATION OF DELOITTE & TOUCHE
AS INDEPENDENT AUDITORS, TO AUDIT THE FINANCIAL STATEMENTS OF THE CORPORATION
AND ITS SUBSIDIARIES FOR THE YEAR ENDING DECEMBER 31, 1994.
 
COST OF SOLICITATION OF PROXIES
 
     The cost of soliciting Proxies will be borne by MCN and the solicitation
will be made by use of the mails, personally or by telephone or telegraph by
officers, directors and regular employees of MCN and its subsidiaries who will
not be additionally compensated therefor. The firm of Corporate Investor
Communications, Inc. has been retained to assist with the solicitation of broker
and nominee Proxies at a cost of approximately $6,000. MCN will also reimburse
banks, brokers, nominees and other fiduciaries for reasonable expenses incurred
by them in forwarding the Proxy material to the beneficial owners of MCN Common
Stock.
 
FILINGS UNDER SECTION 16(a)
 
     Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
officers and directors to file reports with the Securities and Exchange
Commission of ownership and changes in ownership of the Company's equity
securities. The Company believes that during the 1993 fiscal year, all filing
requirements applicable to its officers and directors were complied with, except
Dale A. Johnson's filing on June 15, 1993, rather than June 10, 1993, of a Form
4, Statement of Changes in Beneficial Ownership of Securities, with respect to
his purchase on May 6, 1993 of 300 shares of MCN Common Stock.
 
SHAREHOLDER PROPOSALS
 
     Shareholder proposals to be considered for inclusion in MCN's 1995 proxy
statement for presentation at the 1995 Annual Meeting of Shareholders must be
received by the Secretary of MCN at 500 Griswold Street, Detroit, Michigan
48226, no later than November 8, 1994. Other shareholder proposals concerning
business to be conducted at MCN's annual meeting must be received by the
Secretary of MCN at 500 Griswold Street, Detroit, Michigan 48226 not earlier
than January 28, 1995 nor later than February 27, 1995.

                     NON-OFFICER DIRECTOR STOCK AWARD PLAN

                                STOCK AWARD PLAN
 
     1. ESTABLISHMENT. MCN Corporation ("MCN") hereby establishes the MCN
Corporation Non-officer Director Stock Award Plan (the "Plan"), as set forth in
this document.
 
     2. PURPOSE. The purpose of the Plan is to enhance MCN's ability to attract
and retain the services of well-qualified directors who are not officers or
employees of MCN or any of its subsidiaries ("Non-officer Directors") by
providing them with an opportunity to participate in the growth of MCN and to
align the personal interests of Non-officer Directors with those of MCN's
stockholders.
 
     3. DURATION OF THE PLAN. The Plan shall become effective immediately upon
approval of MCN's Board of Directors, subject to ratification by MCN's
stockholders, within one year of the Board of Director's approval, by an
affirmative vote of a majority of shares voting at the stockholders' meeting, so
long as a quorum is present. The Plan shall remain in effect until terminated by
action of the Board of Directors.
 
     4. SHARES ISSUABLE UNDER THE PLAN. Subject to adjustment as provided in
Paragraph 5, the total number of shares of common stock of MCN ("Common Stock")
which may be granted under the Plan in each year during which the Plan is in
effect shall be the aggregate number of shares payable to the Non-officer
Directors as set forth in Paragraph 6 of the Plan, not to exceed .03 percent of
the total number of outstanding shares of MCN Common Stock as of the first day
of that year. Shares to be issued under the Plan may be authorized and unissued
shares or authorized and issued shares of Common Stock which have been
reacquired by MCN and held as treasury shares. Provided, however, that the
number of Shares that may be issued under this Plan subsequent to March 1, 1994
may not exceed 1% of the number of shares issued and outstanding on March 1,
1994.
 
     5. CAPITAL ADJUSTMENTS. The aggregate number and class of shares subject to
and authorized by the Plan shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from the
payment of a stock dividend, stock split, recapitalization, merger,
consolidation, reorganization or any similar capital adjustment or other
increase or decrease in the number of outstanding shares effected without
receipt of consideration by MCN.
 
     6. GRANTS OF COMMON STOCK. On the business day next following the date of
the Annual Meeting of the Shareholders of MCN held during each calendar year
during which the Plan is in effect (the "Date of Grant"), each Non-officer
Director who was elected at that meeting or whose term continued thereafter as a
Director at such meeting shall be granted 100 shares of Common Stock. The shares
granted pursuant to this Plan shall be in addition to, and not in lieu of, the
Non-officer Director's annual retainer fee, meeting fees, or other compensation
payable to each Non-officer Director as a result of his or her service on MCN's
Board of Directors. The number of shares to be granted annually to each
Non-officer Director may be changed by a majority vote of MCN's
 
                                       23
<PAGE>   27
Board of Directors, provided, however, that any changes in the number of shares
granted shall be made no more often than once in any 12-month period.
 
     7. TRANSFERABILITY. The shares of Common Stock granted to each Non-officer
Director are not transferable by the Non-officer Director until the later of (1)
the expiration of six months from the date the shares of Common Stock are issued
under the Plan or (2) the date upon which the Non-officer Director ceases to be
a Director of MCN, provided, however, that there shall be no restriction on the
transfer of any Common Stock granted under the Plan in the event of the death of
the recipient.
 
     8. RIGHTS OF THE STOCKHOLDER. A Non-officer Director shall have no rights
as a stockholder with respect to any shares of Common Stock granted under the
terms of this Plan until the Non-officer Director shall have become the holder
of record of any such shares, and no adjustment shall be made for dividends in
cash or other property or distributions of other rights with respect to any such
shares of Common Stock for which the record date is prior to the date on which
the Non-officer Director shall have become the holder of record of any such
shares.
 
     9. TERMINATION OF SERVICE AS A NON-OFFICER DIRECTOR. In the event a
Non-officer Director ceases to serve on the Board of Directors as a Director,
all rights to receive future grants of Common Stock hereunder shall terminate
immediately.
 
     10. AMENDMENT OF PLAN. The Board of Directors may terminate, amend or
modify the Plan at any time and from time to time; provided, however, that such
amendments may not be made more than once every six months, other than to
comport with changes in the Internal Revenue Code, the Employee Retirement
Income Security Act or the rules thereunder. Further, the Board of Directors
shall not, without the requisite affirmative approval of stockholders of MCN,
make any amendment which requires stockholder approval under any applicable law,
including Rule 16b-3 under the Securities Exchange Act of 1934, unless such
compliance, if discretionary, is no longer desired.
 
     11. COMPLIANCE WITH RULE 16B-3. It is intended that the Plan be applied and
administered in compliance with Rule 16b-3 under the Securities and Exchange Act
of 1934. If any provision of the Plan would be in violation of Rule 16b-3 if
applied as written, such provision shall not have effect as written and shall be
given effect so as to comply with Rule 16b-3, as determined by the Board of
Directors.
 
     12. SECURITIES LAW RESTRICTIONS. MCN may impose such other restrictions on
any shares of Common Stock granted pursuant to this Plan as it may deem
advisable including, but not limited to, restrictions intended to achieve
compliance with the Securities Act of 1933, as amended, with the Securities and
Exchange Act of 1934, as amended, with the requirements of any stock exchange
upon which the Common Stock is then listed, and with any Blue Sky or state
securities laws applicable to such Common Stock.
 
     13. GOVERNING LAW. All determinations made and actions taken pursuant to
the Plan shall be governed by the laws of the State of Michigan and construed in
accordance therewith, to the extent not preempted by the laws of the United
States.
