These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the accompanying financial statements present fairly, in all material respects, the assets available for benefits of the Plan at December 31, 1997 and 1996, and the changes in assets available for benefits for the year ended December 31, 1997, in conformity with generally accepted accounting principles. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules listed in the Table of Contents are presented for the purpose of additional analysis and are not a required part of the basic financial statements, but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental information by fund in the statement of assets available for benefits and the statement of changes in assets available for benefits is presented for the purpose of additional analysis rather than to present the assets available for benefits and changes in assets available for benefits of the individual funds. These supplemental schedules and supplemental information by fund is the responsibility of the Plan's management. Such supplemental schedules and supplemental information by fund have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects when considered in relation to the basic financial statements taken as a whole.

PLAN DESCRIPTION The following description of the MCN Energy Group Savings and Stock Ownership Plan (the Plan) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan's provisions. GENERAL The Plan is a defined contribution benefit plan for employees not covered by the collective bargaining agreements who have attained one year of service and are age 21 or older. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The Plan is sponsored solely by MCN Energy Group Inc. (MCN) and is maintained for the benefit of employees of MCN and any subsidiary or affiliate of MCN which may adopt the Plan from time to time. The employers participating in the Plan are MichCon, MCN Energy Group Inc., and MCN Investment Corporation and some of its subsidiaries. CONTRIBUTIONS Each employee electing to participate in the Plan is required to make regular contributions by payroll deduction. Participant contributions, including any Salary Reduction Allotments, are limited to 15% (for highly compensated participants) and 20% (for nonhighly compensated participants) of the participant's compensation as defined in the Plan ("Eligible Compensation"), or such maximum rates as may be approved by the Internal Revenue Service. Effective April 1, 1998, participant contributions are limited to 17% (for nonhighly compensated participants) of the participant's Eligible Compensation. Participants may elect to have their Eligible Compensation reduced (Salary Reduction Allotments) by up to 9% (highly compensated participants 8%) and have that amount contributed to the Plan. The employers' make matching contributions to the Plan on behalf of each participant which are limited to 4% of the participant's Eligible Compensation for individuals with less than 10 years of service. For those individuals who have completed at least 10 years of service, the limit is 5% of the participant's Eligible Compensation. Effective January 1, 1999, after a participant has completed 9 years of service, the limit is 5% of the participant's Eligible Compensation. However, some of the participants Eligible Compensation will include overtime wages and bonuses. Participants with more than 23 years of service are matched up to 6%. Seventy-five percent of all employer matching contributions is allocated to the MCN Restricted Stock Fund. Each Employer shall contribute annually (April 1st) to the MCN Restricted Stock Fund accounts for each of its participating Employees on active payroll who have at least 30 years of service, twenty-five shares of MCN Stock (or an equivalent value determined by the Committee in a nondiscriminatory manner, which may be used to purchase MCN Stock). 4 9 MCN ENERGY GROUP SAVINGS AND STOCK OWNERSHIP PLAN NOTES TO FINANCIAL STATEMENTS PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contribution, allocations of the Company's contributions and Plan earnings. Allocations are based on participant earnings or account balances, as defined. Forfeited balances of terminated participants' nonvested accounts are used to reduce future employer contributions. The benefit to which the participant is entitled is the benefit that can be provided from the participant's vested account. VESTING Participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the employer's matching contribution portion of their accounts plus actual earnings thereon occurs after completion of five years of service. INVESTMENT OPTIONS Participants may transfer existing account balances in the investment funds on a daily basis with the exception of the MCN Restricted Stock Fund. However, participants may change their investment direction and amount of future contributions effective with the next payroll period. With respect to the MCN Stock Fund, Company designated insider traders are limited to a 30-day window following the release of quarterly earnings. Contributions may be directed in any of the following savings options: MCN Stock Fund - Fund invests solely in the common stock of MCN Energy Group Inc.

The unrestricted fund includes any employee contributions and possibly any portion of the remaining 25% of the employer matching contributions. All 1997 MCN dividends accumulated under the ESOP were passed through to each participant in March 1998 unless the participant elected not to receive such dividends. Putnam Global Growth Fund - Fund consists primarily of common stocks traded in securities markets located in a number of foreign countries and in the United States. Putnam Fund for Growth and Income - Fund consists primarily of common stocks that offer potential for capital growth, current income, or both. The fund may also purchase corporate bonds, notes and debentures, preferred stocks, or convertible securities (both debt securities and preferred stocks) or U.S. government securities.

The investments of the Fixed Income Fund consists of the following: - contracts with insurance companies and other financial institutions providing for fixed rates of interest, and - investments in specific government and corporate marketable fixed income securities, which are managed by professional investment advisors. 5 10 MCN ENERGY GROUP SAVINGS AND STOCK OWNERSHIP PLAN NOTES TO FINANCIAL STATEMENTS Amounts invested in marketable securities are invested through or pursuant to contracts with insurance companies. These contracts provide for a guarantee of the principal invested and accrued interest under the contract. The interest rates under these contracts are adjusted at least annually to recognize the impacts of changing interest rate conditions. Investment advisors for marketable fixed income securities may use fixed income futures and options to reduce the effect of market volatility on the Fund. Putnam Voyager Fund - Fund consists primarily of common stocks of companies with potential for capital appreciation which is significantly greater than that of the market averages and generally invests a significant portion of its assets in the securities of smaller and newer issuers. Putnam New Opportunities Fund - Fund consists primarily of common stocks of companies in sectors of the economy with potential for capital appreciation which is significantly greater than that of the market averages and generally invests a significant portion of its assets in the securities of small to mid-sized companies. Putnam Income Fund - Fund consists primarily of quality corporate and government bonds that pay out a rate of interest in regularly scheduled payments. The fund also invests in selected below-investment grade bonds, which have a higher risk of nonpayment of interest and principal. ADMINISTRATIVE AND BROKERAGE FEES Expenses in connection with the purchase or sale of stock or other securities are charged to the participant for which the purchases or sales are made. Participants pay 100% of the investment management and other related expenses of the funds. The participating employers pay 100% of the recordkeeping and Trustee expenses. LOANS Subject to limitations imposed by the Internal Revenue Code and Department of Labor regulations, Plan provisions allow a participant to borrow from the Plan an amount up to 50% of the vested value of his or her salary reduction and ESOP accounts, up to a maximum of $50,000, at an interest rate of 2 1/2% over prime updated quarterly (rounded to the nearest 1/2 %). The outstanding balances of loans are reported in the Loan fund. A participant may have only one loan outstanding at a time and loan refinances are available every twelve months. TERMINATION OF THE PLAN Although it has not expressed any intent to do so, the Employers have the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, the Plan assets shall be distributed ratably to the participants in proportion to the total values of their respective Plan accounts. Each participating employer may withdraw from or terminate its participation in the Plan at any time. Under these circumstances, the Committee shall direct the Trustee to (1) segregate, in a separate trust, amounts held under the Plan which are applicable to the participants of such 6 11 MCN ENERGY GROUP SAVINGS AND STOCK OWNERSHIP PLAN NOTES TO FINANCIAL STATEMENTS employer (in the event of withdrawal); or (2) distribute to the participants of such employer amounts attributable to such participants' investments under the Plan (in the event of termination). 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accompanying financial statements are prepared under the accrual method of accounting. Purchase and sales of securities are recorded on the trade date basis. Dividend income is recorded on the ex-dividend date. Income from other securities is recorded when earned. Investments are stated at market value, which is generally based on quoted prices. A portion of the Fixed Income Fund is reported on a contract value (which represents contributions made under the contract plus earnings, less withdrawals and administrative expenses) because it is fully benefit responsive. Participant loan receivables are presented at cost which approximates fair value. The cost of securities sold or distributed is determined on the basis of average cost. The MCN Stock Fund recognizes gains or losses on stock distributed to terminated participants in settlement of their accounts equal to the difference between cost and market value of the shares distributed. Benefits are recorded when paid. 3. TAX STATUS The Internal Revenue Service has determined and informed MCN by a letter dated November 19, 1997 that the Plan is qualified and related trust is tax exempt and both are designed in accordance with applicable sections of the Internal Revenue Code (IRC). The Plan administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. 4. DEFINED CONTRIBUTION PLANS MASTER TRUST The Master Trust was established on August 1, 1988 and serves as a funding medium to certain employee benefit plans of the Corporation and its subsidiaries and affiliates which are qualified under Section 401(a) of the Internal Revenue Code of 1986 as amended from time to time. Currently, the Master Trust consists of certain commingled assets of the Plan and the MichCon Investment and Stock Ownership Plan. The Plan's investment in the Master Trust in the Statement of Assets Available for Benefits represents the Plan's allocated portion (approximately 80% )of the Master Trust investments. The Plan's allocated portion of the investments is equal to the market value of the Plan's assets contributed, adjusted by the Plan's allocated share of the Master Trust investment income and expenses, employee and employer contributions and distributions and withdrawals paid to participants.
