In 1997, MCN earned net income from continuing operations of $142.3 million and a return on equity of 14.7%. At December 31, 1997, MCN and its subsidiaries had 3,209 employees. With markets and investments throughout North America and in Asia, MCN operates through two major business groups, Diversified Energy and Gas Distribution. The Diversified Energy group is involved in oil and gas exploration and production, gas gathering, processing, transmission and storage, energy marketing, electric power generation and other energy related businesses. The Gas Distribution group consists primarily of Michigan Consolidated Gas Company, a natural gas distribution and transmission company serving 1.2 million customers in more than 500 communities throughout the State of Michigan. MCN currently plans to use asset sales and purchases as a key tool in optimizing its portfolio of businesses. As MCN continues to expand its businesses both domestically and internationally, it expects to focus on larger acquisitions of properties and companies to add to its base of expertise and expand the breadth of its investments. As a result, MCN will take on a more direct role in the operation of some of its joint ventures within the Diversified Energy Group. MCNIC GENERAL MCNIC, a wholly-owned subsidiary of MCN, is a subsidiary holding company for MCN's Diversified Energy group and is involved in the following businesses: (i) Exploration and Production, with 1.3 trillion cubic feet equivalent of proved gas and oil reserves at December 31, 1997, in the Midwest/Appalachia, Midcontinent/Gulf Coast and Western regions of the United States; (ii) Pipelines and Processing, with gathering, processing and transmission facilities near areas of rapid reserve development and growing consumer markets; (iii) Energy Marketing, with total gas sales and exchange delivery markets of 358.8 billion cubic feet ("Bcf") for 1997; (iv) Electric Power, with investments in electric generation facilities in operation and under development with a combined 2,804 megawatts ("MW") of gross capacity and investments in electric distribution facilities; and (v) Gas Storage, with investments in storage facilities that have 52 Bcf of storage capacity, 42 Bcf of which is currently under development. The Diversified Energy group's operating revenues for 1997 totaled $951.3 million (including intercompany transactions), while operating and joint venture income was $112.7 million in 1997, nearly double the 1996 operating and joint venture income. The Diversified Energy group contributed 43% of the Company's earnings, up from 28% in 1996. Within the Diversified Energy group's individual business units, operating and joint venture income rose 75% for Exploration & Production, 172% for Pipelines & Processing, and 113% for Energy Marketing, Electric Power and Gas Storage. Partially offsetting the growth in earnings were increased financing costs resulting from additional capital needed to fund investments. EXPLORATION & PRODUCTION The Company is engaged in natural gas and oil exploration, development and production through its wholly owned subsidiary, MCNIC Oil & Gas Company ("MOG"). At December 31, 1997, proved gas reserves totaled 1,166.2 Bcf and proved oil reserves were 155.1 billion cubic feet equivalent ("Bcfe"), up a combined 80.2 Bcfe, or 7%, from December 1996 levels. The increase in gas and oil reserves during 1997 was tempered by the sale of properties with 57.6 Bcfe of proved reserves and net downward reserve revisions of 32.8 Bcfe. Operating and joint venture income for 1997 increased by $24.9 million over 1996 to $58.1 million, reflecting a significant increase in gas and oil production during 1997 to 98.3 Bcfe from 63.7 Bcfe in 1996. Approximately $17.8 million in federal tax credits were generated in 1997 related to gas production from certain Antrim and coalbed methane gas wells. S-3 4 MOG's strategy is to continue to grow its U.S. gas reserve base and production in known producing areas through drilling and acquisition, generating attractive returns. MOG is also pursuing international opportunities in areas with known hydrocarbons involving both lower risk, unconventional long-life reserves and higher risk, conventional exploration and development prospects with substantial upside potential. Although MOG may increase its operating role in the future, currently it takes primarily a non-operating, but active role, investing with operators with local expertise in each play. MOG anticipates that production will increase in the future through the continued development of its large inventory of unconventional and conventional drilling locations and from additional exploration and development of MOG's approximately 1.2 million net (2.6 million gross) acres of undeveloped property. In 1997, MOG participated in the drilling of 696 wells (412 net), bringing the total drilled to 2,273 wells (1,47 net) since it began operations in 1992. The 1997 drilling program achieved an overall drilling success rate of 91% and added approximately 269 Bcfe of proved reserves. MOG's success rate in its drilling program since its inception in 1992 has averaged approximately 91%. During 1997, approximately 42% of MOG's production and 71% of its proved reserves were associated with the Midwest/Appalachia region, as MOG added 257 net wells in the region. Approximately 33% of production and 14% of reserves were from the Midcontinent/Gulf Coast, and the Western region became a significantly larger piece of the business, accounting for 25% of production and 15% of reserves, compared with only 6% and 9%, respectively, in 1996. In 1997, MOG made significant investments in natural gas reserves, acquiring interests in more than 32 producing wells. At December 31, 1997, 2,917 wells were producing. An additional 384 wells were in various stages of completion and are expected to begin producing in 1998. MCN follows the full-cost accounting method prescribed by the Securities and Exchange Commission for investments in gas and oil properties. Under the full-cost method, substantially all acquisition, exploration and development costs are capitalized. To the extent such capitalized costs exceed the "ceiling," the excess is written off to income. The ceiling is the sum of discounted future net cash flows from proved gas and oil reserves (using unescalated prices and costs unless contractual arrangements exist), and the costs of unproved properties after income tax effects. The ceiling test is applied at the end of each quarter and requires a write-down of gas and oil properties if the ceiling is exceeded, even if any price decline is temporary. Management's investment and operating decisions are based upon prices, costs and production assumptions that are different from those used to compute the ceiling. As a result, it is possible that future fluctuations in key forecast assumptions could result in impairments being recorded for accounting purposes, when long-term economics of such properties have not changed. It is anticipated that MCN will invest in excess of $400 million in exploration and production activities in each of 1998 and 1999. PIPELINES & PROCESSING Operating and joint venture income for this unit, managed by MCNIC Pipeline & Processing Company, nearly tripled from $10.7 million in 1996 to $29.1 million in 1997 due to full-year contributions from projects added in 1996 and strong growth across the range of its businesses. Transportation volumes increased in 1997 to 116.0 Bcf from 86.4 Bcf in 1996, while there was a slight decrease in processing volumes in 1997 to 42.8 Bcf from 44.2 Bcf in 1996. Results also reflect a significant contribution of methanol production totaling 60.8 million gallons, compared with the initial 1996 production of 10.5 million gallons, from the Company's partnership with Lyondell Petrochemical Co. ("Lyondell"), formed in late 1996. Earnings from Lyondell also benefited from higher than expected methanol prices during 1997. The Pipelines & Processing group's strategy is to own interests in natural gas and gas liquid gathering, processing and transmission facilities near areas of rapid reserve development or growing consumer markets. This strategy includes working with other Diversified Energy group businesses that complement the Pipelines & Processing group's operations. Operating responsibilities for these facilities are generally assigned to the Company's partners. S-4 5 MCN's strategy to grow its pipelines and processing operations is to take equity positions, usually in partnerships owning natural gas gathering, processing and transmission facilities near areas of either rapid reserve development or growing consumer markets. It is anticipated that in excess of $350 million will be invested in pipelines and processing facilities in 1998, a level of investment that could rise significantly in future years based on the numerous potential domestic and international projects currently being pursued. ENERGY MARKETING, GAS STORAGE & ELECTRIC POWER Operating and joint venture income for 1997 for the combined results of these three businesses more than doubled to $29.8 million from $14.0 million in 1996. The improvement reflects the acquisition in May of an interest in the Midland Cogeneration Venture ("MCV") in Michigan, as well as gas sales and exchange deliveries that increased 49% to 359 Bcf in 1997 from 242 Bcf in 1996. These volumes include 61.4 Bcf of supply-area sales added due to the marketing alliance with Torch Energy Advisors of Houston, which began operations in early 1997. Capital investments for the combined marketing, storage and electric power units during 1997 totaled approximately $250 million, compared with $21 million in 1996, and are anticipated to exceed $250 million in 1998. These capital investments primarily target electric power generation projects. ENERGY MARKETING MCN's non-regulated energy marketing activities are directed by CoEnergy Trading Company ("CTC"). CTC, a wholly owned subsidiary of the Company, is engaged in the purchase and sale of natural gas to over 700 commercial and industrial users, as well as gas and electric utilities and other large-volume customers throughout the Midwest, Gulf Coast and Northeast regions of the United States and Eastern Canada. Through its offices located in Hartford, Connecticut, and Detroit and Grand Rapids, Michigan, CTC is able to offer buyers a bundled service by making arrangements for the acquisition of the required gas volumes and delivery to customers' facilities, and for all the necessary services in between. This bundled service is more in demand during the winter months, when interstate pipeline capacity in certain areas of the Northeast and Midwest is either constrained or uneconomical. CTC is able to better meet this demand through the use of gas production and access to storage fields and other physical assets owned by affiliates. CTC competes against numerous marketing companies. A diverse portfolio of short, medium and long-term sales and supply contracts combined with access to reliable gas suppliers, storage facilities and multiple pipeline connections enhances its competitive position. CTC uses its competitive position in both the market and production regions to identify and complement business opportunities for the Company's various businesses. Also assisting the Company's marketing efforts is strategically selected pipeline capacity that is used to deliver gas to Midwestern, Northeastern and Canadian customers. The Company expects to increase its reserved pipeline capacity, particularly on recently proposed west-to-east systems, to help meet customers' needs. In addition to the Company's anticipated equity interests in three of these projects, CTC expects to capture significant marketing opportunities utilizing the new pipelines. GAS STORAGE The Company, through its subsidiary MCNIC Gas Storage Company ("MCNIC Gas Storage"), has adopted a strategy of using joint ventures and strategic partnerships to provide gas storage services, either as a separate service or bundled with full gas service, to other gas utilities, pipeline companies and large-volume gas users. Storage facilities near major consuming markets provide supply flexibility, improve reliability of deliveries and help reduce gas costs. The Company's 35 Bcf of owned and leased storage capacity in Michigan allows the Company to flow gas into storage at relatively steady rates during off-peak periods, and to draw upon this storage for delivery during peak-demand periods. The Company believes that this strategy allows for a very reliable service while keeping operating costs low. The gas industry's changing operating environment has resulted in more efficient use of existing storage facilities and a reduced immediate need for additional capacity. However, growing markets will require expanded storage capabilities in selected areas in the long-term. The Company believes that this future need, S-5 6 together with Michigan's pivotal geographic location and favorable geology, presents a significant opportunity for MCN's storage services. During August 1997, MCNIC began developing the $160 million Washington 10 storage field project that will significantly increase the amount of gas storage capacity available to CTC for its markets. The Washington 10 storage field project is in the process of converting a depleted gas reservoir in southeast Michigan to a 42 Bcf storage facility, capable of delivering approximately 400 MMcf of natural gas on an average winter day and much higher volumes during peak-demand periods. Initial gas injection is currently scheduled for the spring of 1999, with the facility currently expected to be fully operational in time for the 1999-2000 winter heating season. ELECTRIC POWER The Company's Electric Power unit operates through MCNIC Power Company ("MCNIC Power"), MCNIC International Holdings and MCNIC-GP International Holdings, wholly owned subsidiaries of the Company, to pursue domestic and international power generation-related opportunities. Power generation projects offer the potential for multiple sources of income, such as long-term gas sales, transportation services and a return on the investment in the facility, particularly in the United States. In recent years, an increasing amount of new electric generating capacity has been fueled by natural gas because of the lower capital costs, lower emissions and other advantages associated with natural gas- fueled facilities. In addition, many states have passed regulations requiring electric utilities to consider bids from third parties to meet new electric generation needs. The Company believes that MCNIC Power has the capacity to provide long-term gas supplies at known prices to power generation facilities. MCNIC Power's strategy is to capture synergies among MCN's businesses and to profitably apply the expertise they have gained in managing energy-related projects. The gas-fueled power generation industry has seen an increase in the number of participants, many of whom are willing to accept returns on power generation projects that are considerably below MCNIC Power's threshold. The restructuring of the electric utility industry could increase the long-term opportunities for MCNIC Power. The Company believes that MCN's experience in the natural gas industry's transition to a more competitive environment, combined with its success as a partner in several independent power projects, should enable it to capture such opportunities. Electric Power sales increased 160% to 1.8 million MW hours ("MWh") in 1997 from 700,000 MWh in 1996, primarily due to the addition of interests in MCV in April 1997 and a power generation and distribution partnership in India in March 1997. Net generating capacity climbed to 506 MW from 91 MW. The Company's experience and relationships in the energy business have provided a solid base with which to pursue opportunities internationally. The Company believes that India holds significant investment potential, where there is tremendous demand for additional power generation capacity and the business environment remains conducive to attractive returns on investment. The Company's strategy in India is to partner with others who bring expertise and capital to the venture, including an experienced Indian partner. In March 1997, the Company made its first international investment with the formation of Torrent Power Ltd. ("Torrent"), a venture with Torrent Exports Ltd., of Ahmedabad, India. The Company's investment of approximately $173 million gives it a 40% interest in Torrent and its growing electricity generation and distribution business in the state of Gujarat in western India. Entering 1998, MCN is pursuing opportunities to participate in the construction of more than 5,000 additional gross MW of generating capacity in India. Among them are a 525 MW coal-fired facility in the state of Tamil Nadu and a 347 MW dual-fuel project in the state of Madhya Pradesh, as well as several captive power projects ranging from 20 MW to 210 MW in various locations. RISK MANAGEMENT STRATEGY MCN primarily manages commodity price risk by utilizing futures, options and swap contracts to more fully balance its portfolio of gas and oil supply and sales agreements. MCN has hedged through long-term financial swaps most of its anticipated future gas production not covered by long-term, fixed-price sales S-6 7 obligations. MCN's Energy Marketing group coordinates all of MCN's hedging activities. A management committee ensures compliance with risk management policies and periodically reports to MCN's board of directors. Certain hedging gains or losses related to gas and oil production are recorded by MCN's Exploration & Production group. Gains and losses on gas hedging transactions that are not recorded by MCN's Exploration & Production group are absorbed by the Energy Marketing group.

Each Dealer shall be provided with (A) the name of the Company, (B) an estimate of the Purchase Price (which shall be stated as a U.S. dollar amount and be calculated by the Calculation Agent in accordance with clause (c) below), (C) the principal amount and maturity of the REPS and (D) the method by which interest will be calculated on the REPS. (c) The Purchase Price to be paid by any Dealer for the REPS (the "Purchase Price") shall be equal to (i) the principal amount of the REPS plus (ii) a premium (the "REPS Premium") which shall be equal to the excess, if any, of (A) the discounted present value to the Coupon Reset Date of a bond with a maturity of April 1, 2008, which has an interest rate of 5.61%, semiannual interest payments on each April 1 and October 1, commencing October 1, 2003 and a principal amount of $100,000,000, and assuming a discount rate equal to the Treasury Rate over (B) $100,000,000. "Treasury Rate" for the REPS means the per annum rate equal to the offer side yield to maturity of the current-on-the-run five-year United States Treasury Security per Telerate page 500 (or any successor or substitute page as may replace such page on such service) at 11:00 a.m., New York City time, on the applicable Bid Date (or such other date or time that may be agreed upon by the Company and the Calculation Agent) or, if such rate does not appear on Telerate page 500 (or any successor or substitute page as may replace such page on such service) at such time, the rates on GovPx End-of-Day Pricing at 3:00 p.m. on the applicable Bid Date (or such other date or time that may be agreed upon by the Company and the Calculation Agent). (d) The Calculation Agent shall notify the Company by 12:30 p.m., New York City time, on the Bid Date of (i) the names of each of the Dealers from whom the Calculation Agent received Bids on the Bid Date, (ii) the Bid submitted by each such Dealer and (iii) the Purchase Price as determined pursuant to paragraph (c) hereof. Unless the Call Option has terminated, the Calculation Agent shall thereafter select from the Bids received the Bid with the lowest Yield to Maturity (the "Selected Bid") and set the Coupon Reset Rate equal to the interest rate which would amortize the REPS Premium fully over the term of the REPS at the Yield to Maturity indicated by the Selected Bid; provided, however, that if the Calculation Agent has not received a timely Bid from a Dealer, the Selected Bid shall be the lowest of all Bids received by such time and provided, further, that if any two or more of the lowest Bids submitted are equivalent, the Company shall in its sole discretion select any of such equivalent Bids (and such selected Bid shall be the Selected Bid). (e) Immediately after calculating the Coupon Reset Rate, the Calculation Agent shall provide written notice to the Company and the Trustee, setting forth the Coupon Reset Rate. The Coupon Reset Rate for the REPS will be effective from and including the Coupon Reset Rate. S-9 10 (f) The Callholder shall sell the REPS to the Dealer that made the Selected Bid at the Purchase Price, such sale to be settled on the Coupon Reset Date in immediately available funds. If the Calculation Agent (i) determines that since the Call Notice, an Event of Default has occurred and is continuing under Sections 501(1), (2), (3), (4) or (7) of the Indenture (in such event, termination is at the Callholder's option) or under Sections 501(5) or (6) of the Indenture (in such event, termination is automatic), (ii) following the Call Notice, fails to pay the Call Price by 2:00 p.m., New York City time, on the Business Day prior to the Coupon Reset Day due to the occurrence of a Market Disruption Event (as defined below) or (iii) determines that, following the Call Notice, less than two Dealers have provided Bids in a timely manner substantially as provided above, such Call Option will be automatically revoked, and the Trustee will exercise the Mandatory Put on behalf of the holders. "Market Disruption Event" shall mean any of the following: (A) a suspension or material limitation in trading in securities generally on the New York Stock Exchange, Inc. or the establishment of minimum prices on such exchange; (B) a general moratorium on commercial banking activities declared by either federal or New York State authorities; (C) any material adverse change in the existing financial, political or economic conditions in the United States of America; (D) an outbreak or escalation of major hostilities involving the United States of America or a declaration of a national emergency or war by the United States; or (E) any material disruption of the U.S. government securities market, U.S. corporate bond market or U.S. federal wire system; provided, in each case, that in the judgment of the Calculation Agent the effect of the foregoing makes it impracticable to conduct the Coupon Reset Process. The calculation agency agreement provides that the Calculation Agent may resign at any time, such resignation to be effective ten business days after the delivery to the Company and the Trustee of notice of such resignation. In such case, the Company may appoint a successor Calculation Agent. The Calculation Agent, in its individual capacity, may buy, sell, hold and deal in the REPS and may exercise any vote or join in any action which any holder of the REPS may be entitled to exercise or take as if it were not the Calculation Agent. The Calculation Agent, in its individual capacity, may also engage in any transaction with the Company and any of its affiliates as if it were not the Calculation Agent. BOOK-ENTRY SYSTEM The REPS will be represented by one or more Global Securities registered in the name of Cede & Co., the nominee of the Depositary. The Depositary is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. The Depositary holds securities that its participants (the "Direct Participants") deposit with the Depositary. The Depositary also facilitates the settlement among Direct Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Direct Participants' accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. The Depositary is owned by a number of its Direct Participants and by the New York Stock Exchange, Inc., the American Stock Exchange, Inc., and the National Association of Securities Dealers, Inc. Access to the Depositary's system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (the "Indirect Participants," and together with the Direct Participants, the "Participants"). The rules applicable to the Depositary and its Participants are on file with the Securities and Exchange Commission. Purchases of the REPS within the Depositary's system must be made by or through Direct Participants, which will receive a credit for the REPS on the Depositary's records. The ownership interest of each actual purchaser of the REPS (a "Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' respective records. Beneficial Owners will not receive written confirmation from the Depositary of their purchase, but Beneficial Owners are expected to receive written confirmations providing details of the S-10 11 transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the REPS are to be accomplished by entries made on the books of Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in REPS except in the event that use of the book-entry system for the REPS is discontinued. To facilitate subsequent transfers, all REPS deposited by Direct Participants with the Depositary will be registered in the name of Cede & Co. The deposit of the REPS with the Depositary and their registration in the name of Cede & Co. effect no change in beneficial ownership. The Depositary has no knowledge of the actual Beneficial Owners of the REPS; the Depositary's records reflect only the identity of the Direct Participants to whose accounts such REPS are credited, which may or may not be the Beneficial Owners. The Participants will remain responsible for keeping account of their holdings on behalf of their customers. Conveyance of notices and other communications by the Depositary to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Redemption notices shall be sent to Cede & Co. If less than all of the REPS are being redeemed, the Depositary's practice is to determine by lot the amount of the interest of each Direct Participant to be redeemed. Neither the Depositary nor Cede & Co. will consent or vote with respect to the REPS. Under its usual procedures, the Depositary mails an omnibus proxy (an "Omnibus Proxy") to the Participants as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct Participants to whose accounts the REPS are credited on the record date (identified in a listing attached to the Omnibus Proxy). Principal, redemption premium, if any, and interest payments on the REPS will be made to the Depositary. The Depositary's practice is to credit Direct Participants' accounts on the relevant payment date in accordance with their respective holdings shown on the Depositary's records unless the Depositary has reason to believe that it will not receive payment on such payment date. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities for the accounts of customers in bearer form or registered in "street-name," and will be the responsibility of such Participant and not of the Depositary, the Underwriters, or the Company, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, redemption premium, if any, and interest to the Depositary is the responsibility of the Company or the Paying Agent. Disbursement of such payments to Direct Participants is the responsibility of the Depositary, and disbursement of such payments to the Beneficial Owners is the responsibility of Direct and Indirect Participants. Global Securities will settle in immediately available funds in the secondary trading market. No assurance can be given as to the effect, if any, of settlement in immediately available funds on trading activity in the REPS. The Depositary may discontinue providing its services as securities depository with respect to the REPS at any time by giving reasonable notice to the Company. Under such circumstances and in the event that a successor securities depository is not obtained, REPS certificates are required to be printed and delivered. In addition, the Company may decide to discontinue use of the system of book-entry transfers through the Depositary (or a successor securities depository). In that event, REPS certificates will be printed and delivered. The Company will not have any responsibility or obligation to Participants or the persons for whom they act as nominees with respect to the accuracy of the records of the Depositary, its nominee or any Direct or Indirect Participant with respect to any ownership interest in the REPS, or with respect to payments to or providing of notice for the Direct Participants, the Indirect Participants or the Beneficial Owners. S-11 12 CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES The following summary of certain United States Federal income tax consequences of the purchase, ownership and disposition of the REPS is based upon the Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations, Internal Revenue Service ("IRS") rulings and pronouncements and administrative and judicial decisions currently in effect, all of which are subject to change (possibly with retroactive effect) or possible differing interpretations. This summary deals only with REPS held as capital assets (within the meaning of section 1221 of the Code) and does not purport to deal with persons in special tax situations, such as financial institutions, insurance companies, regulated investment companies, real estate investment trusts, dealers in securities or currencies, persons holding REPS as a hedge against currency risk or as a position in a "straddle", or conversion transaction, or persons whose functional currency is not the U.S. dollar. PROSPECTIVE INVESTORS CONSIDERING THE PURCHASE OF THE REPS SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE APPLICATION OF UNITED STATES FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE REPS ARISING UNDER THE LAWS OF ANY OTHER TAXING JURISDICTION. As used herein, the term "U.S. Holder" means a Beneficial Owner of a REPS that is for United States Federal income tax purposes (i) a citizen or resident of the United States, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States or of any political subdivision thereof (other than a partnership that is not treated as a United States person under any applicable Treasury regulations), (iii) an estate whose income is subject to United States Federal income tax regardless of its source, (iv) a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust, or (v) any other person whose income or gain in respect of a REPS is effectively connected with the conduct of a United States trade or business. Notwithstanding the preceding sentence, to the extent provided in Treasury regulations, certain trusts in existence on August 20, 1996, and treated as United States persons prior to such date, that elect to continue to be treated as United States persons also will be a U.S. Holder. As used herein, the term "non-U.S. Holder" means a beneficial owner of a REPS that is not a U.S. Holder. The United States Federal income tax treatment of debt obligations such as the REPS is not entirely certain. Because the REPS are subject to mandatory tender on the Coupon Reset Date, the Company intends to treat the REPS as maturing on the Coupon Reset Date for United States Federal income tax purposes and as being reissued on the Coupon Reset Date should the Callholder sell the REPS pursuant to the Coupon Reset Process. Based on such treatment, interest on the REPS should constitute "qualified stated interest" and generally should be taxable to a U.S. Holder as ordinary interest income at the time such payments are accrued or received (in accordance with the U.S. Holder's regular method of accounting). Under the foregoing, if the REPS are issued to the Holder at par value or alternatively, the excess of the par value over the issue price does not exceed the statutory de minimis amount (generally 1/4 of 1% of the REPS' stated redemption price at the Coupon Reset Date multiplied by the number of complete years to the Coupon Reset Date from its issue date), the REPS will not be treated as having original issue discount. If the REPS are issued at a discount greater than the statutory de minimis amount, a Holder must include original issue discount in income as ordinary interest for United States Federal income tax purposes as it accrues under a constant yield method in advance of receipt of the cash payments attributable to such income, regardless of the Holder's regular method of accounting. In general, the amount of original issue discount included in income by the initial U.S. Holder of a REPS would be the sum of the daily portions of original issue discount with respect to such REPS for each day during the taxable year (or portion of the taxable year) on which such U.S. Holder held such REPS. The "daily portion" of original issue discount on any REPS is determined by allocating to each day in any accrual period a ratable portion of the original issue discount allocable to that accrual period. An "accrual period" may be of any length and the accrual periods may vary in length over the term of the REPS, provided that each accrual period is not longer than one year and each scheduled payment of principal or interest occurs either on the final day of an accrual period or on S-12 13 the first day of an accrual period. The amount of original issue discount allocable to each accrual period generally is equal to the difference between (i) the product of the REPS' adjusted issue price at the beginning of such accrual period and its yield to maturity (appropriately adjusted to take into account the length of the particular accrual period) and (ii) the amount of any qualified stated interest payments allocable to such accrual period. The "adjusted issue price" of a REPS at the beginning of any accrual period is the sum of the issue price of the REPS plus the amount of original issue discount allocable to all prior accrual periods minus the amount of any prior payments on the REPS that were not qualified stated interest payments. Under these rules, U.S. Holders generally will have to include in income increasingly greater amounts of original issue discount in successive accrual periods. Under the foregoing treatment, upon the sale, exchange or retirement of a REPS, a U.S. Holder generally will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange or retirement (other than amounts representing accrued and unpaid interest) and such U.S. Holder's adjusted tax basis in the REPS. A U.S. Holder's adjusted tax basis in a REPS generally will equal such U.S. Holder's initial investment in the REPS increased by any original issue discount included in income and decreased by the amount of any payments, other than qualified stated interest payments, received and amortizable bond premium taken with respect to such REPS. Such gain or loss will generally be capital gain or loss. The highest marginal individual Federal income tax rate (which applies to ordinary income and gain from sales or exchanges of capital assets held for one year or less) is 39.6%. The maximum regular Federal income tax rate on capital gains derived by individual taxpayers is 28% for sales and exchanges of capital assets held for more than one year but not more than eighteen months, and 20% for sales and exchanges of capital assets held for more than eighteen months. All net capital gain of a corporate taxpayer is subject to tax at ordinary corporate income tax rates of up to 35%. There can be no assurance that the IRS will agree with the Company's treatment of the REPS and it is possible that the IRS could assert another treatment. For instance, it is possible that the IRS could seek to treat the REPS as maturing on the Final Maturity Date and to treat the issue price of the REPS as including the value of the Call Option. In the event the REPS were treated as maturing on the Final Maturity Date for United States Federal income tax purposes, because of the Coupon Reset Process, the REPS would be treated as having contingent interest under the Code. In such event, under Treasury regulations governing debt instruments that provide for contingent payments (the "Contingent Payment Regulations"), the Company would be required to construct a projected payment schedule for the REPS, based upon the Company's current borrowing costs for comparable debt instruments of the Company, from which an estimated yield on the REPS would be calculated. A U.S. Holder would be required to include in income original issue discount in an amount equal to the product of the adjusted issue price of the REPS at the beginning of each interest accrual period and the estimated yield of the REPS. In general, for these purposes, a REPS' adjusted issue price would equal the REPS' issue price increased by the interest previously accrued on the REPS, and reduced by all payments made on the REPS. As a result of the application of the Contingent Payment Regulations, it is possible that a U.S. Holder would be required to include interest in income in excess of actual cash payments received for certain taxable years. In addition, the character of any gain or loss, upon the sale or exchange of a REPS (including a sale pursuant to the mandatory tender on the Coupon Reset Date) by a U.S. Holder, will likely differ if the REPS were treated as contingent payment obligations. Any such taxable gain generally would be treated as ordinary income. Any such taxable loss generally would be ordinary to the extent of previously accrued original issue discount, and any excess would generally be treated as capital loss. NON-U.S. HOLDERS A non-U.S. Holder will not be subject to United States Federal income taxes on payments of principal, premium (if any) or interest (including original issue discount, if any) on a REPS, unless such non-U.S. Holder is a direct or indirect 10% or greater shareholder of the Company, a controlled foreign corporation related to the Company or a bank receiving interest described in section 881(c)(3)(A) of the Code. To S-13 14 qualify for the exemption from taxation, the last United States payor in the chain of payment prior to payment to a non-U.S. Holder (the "Withholding Agent") must have received in the year in which a payment of interest or principal occurs, or in either of the two preceding calendar years, a statement that (i) is signed by the Beneficial Owner of the REPS under penalties of perjury, (ii) certifies that such owner is not a U.S. Holder and (iii) provides the name and address of the Beneficial Owner. The statement may be made on an IRS Form W-8 or a substantially similar form, and the Beneficial Owner must inform the Withholding Agent of any change in the information on the statement within 30 days of such change. If a REPS is held through a securities clearing organization or certain other financial institutions, the organization or institution may provide a signed statement to the Withholding Agent. However, in such case, the signed statement must be accompanied by a copy of the IRS Form W-8 or the substitute form provided by the Beneficial Owner to the organization or institution. The Treasury Department is considering implementation of further certification requirements aimed at determining whether the issuer of a debt obligation is related to holders thereof. Generally, a non-U.S. Holder will not be subject to United States Federal income taxes on any amount which constitutes gain upon retirement or disposition of a REPS, provided the gain is not effectively connected with the conduct of a trade or business in the United States by the non-U.S. Holder. Certain other exceptions may be applicable, and a non-U.S. Holder should consult its tax advisor in this regard. The REPS will not be includible in the estate of a non-U.S. Holder unless the individual is a direct or indirect 10% or greater shareholder of the Company or, at the time of such individual's death, payments in respect of the REPS would have been effectively connected with the conduct by such individual of a trade or business in the United States. BACKUP WITHHOLDING Backup withholding of United States Federal income tax at a rate of 31% may apply to payments made in respect of the REPS to registered owners who are not "exempt recipients" and who fail to provide certain identifying information (such as the registered owner's taxpayer identification number) in the required manner. Generally, individuals are not exempt recipients, whereas corporations and certain other entities generally are exempt recipients. Payments made in respect of the REPS to a U.S. Holder must be reported to the IRS, unless the U.S. Holder is an exempt recipient or establishes an exemption. Compliance with the identification procedures described in the preceding section would establish an exemption from backup withholding for those non-U.S. Holders who are not exempt recipients. In addition, upon the sale of a REPS to (or through) a broker, the broker must withhold 31% of the entire purchase price, unless either (i) the broker determines that the seller is a corporation or other exempt recipient or (ii) the seller provides, in the required manner, certain identifying information and, in the case of a non-U.S. Holder, certifies that such seller is a non-U.S. Holder (and certain other conditions are met). Such a sale must also be reported by the broker to the IRS, unless either (i) the broker determines that the seller is an exempt recipient or (ii) the seller certifies its non-U.S. status (and certain other conditions are met). Certification of the registered owner's non-U.S. status would be made normally on an IRS Form W-8 under penalties of perjury, although in certain cases it may be possible to submit other documentary evidence. Any amounts withheld under the backup withholding rules from a payment to a Beneficial Owner would be allowed as a refund or a credit against such Beneficial Owner's United States Federal income tax provided the required information is furnished to the IRS. FINAL WITHHOLDING REGULATIONS The Treasury Department recently issued final Treasury regulations (the "Final Regulations") which make certain modifications to the withholding, backup withholding and information reporting rules described above. The Final Regulations attempt to unify certification requirements and modify reliance standards. The Final Regulations will generally be effective for payments made after December 31, 1999, subject to certain transition rules. Prospective investors are urged to consult their own tax advisors regarding the Final Regulations. S-14 15 UNDERWRITERS Under the terms and subject to the conditions set forth in the Underwriting Agreement, dated the date hereof (the "Underwriting Agreement"), the Underwriters named below have severally agreed to purchase, and the Company has agreed to sell to them, severally, respective principal amounts of the REPS set forth opposite their respective names below: PRINCIPAL NAME AMOUNT ---- --------- Morgan Stanley & Co. Incorporated........................... $ 50,000,000 First Chicago Capital Markets, Inc. ........................ 50,000,000 ------------ Total....................................................... $100,000,000 ============ Under the terms of the Underwriting Agreement, the Underwriters are committed to take and pay for all of the REPS if any are taken. The Underwriters initially propose to offer the REPS directly to the public at the public offering price set forth on the cover page hereof and in part to certain securities dealers at such price less a concession of .35% of the principal amount of the REPS. The Underwriters may allow, and such dealers may reallow, a concession not in excess of .25% of the principal amount of the REPS to certain brokers and dealers. After the REPS are released for sale to the public, the offering price and other selling terms may from time to time be varied by the Underwriters. The Company has agreed to indemnify the several Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or contribute to payments the Underwriters may be required to make in respect thereof. The Company does not intend to apply for listing of any of the REPS on a national securities exchange, but has been advised by the Underwriters that they presently intend to make a market in the REPS, as permitted by applicable laws and regulations. The Underwriters are not obligated, however, to make a market in the REPS and any such market-making may be discontinued at any time at the sole discretion of the Underwriters. Accordingly, no assurance can be given as to the liquidity of, or trading markets for, the REPS. In order to facilitate the offering of the REPS, the Underwriters may engage in transactions that stabilize, maintain or otherwise affect the prices of the REPS. Specifically, the Underwriters may overallot in connection with the offering, creating a short position in the REPS for their own account. In addition, to cover overallotments or to stabilize the price of the REPS, the Underwriters may bid for, and purchase, the REPS in the open market. Finally, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the REPS in the offering, if the syndicate repurchases previously distributed REPS in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market prices of the REPS above independent market levels. The Underwriters are not required to engage in these activities, and may end any of these activities at any time. In the ordinary course of business, the Underwriters and their respective affiliates have engaged and may in the future engage in investment banking transactions with the Company and certain of its affiliates.

ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE. ------------------------ The date of this Prospectus is March 18, 1998. 18 AVAILABLE INFORMATION MCN is subject to the informational requirements of the Securities Exchange Act of 1934, as amended (the "1934 Act") and in accordance therewith files reports, proxy statements and other information with the Securities and Exchange Commission (the "SEC"). Such reports, proxy statements and other information concerning MCN can be inspected and copied at the public reference facilities maintained by the SEC at Judiciary Plaza, 450 Fifth Street, N.W., Washington, DC 20549, and at the following Regional Offices of the SEC: 7 World Trade Center, Suite 1300, New York, New York 10048; and Citicorp Center, 500 West Madison Street, Suite 1400, Chicago, Illinois 60661. Copies of such material can be obtained from the Public Reference Section of the SEC at Judiciary Plaza, 450 Fifth Street, N.W., Washington, DC 20549, at prescribed rates. The SEC also maintains a Web site on the Internet at http://www.sec.gov that contains reports, proxy and information statements and other information regarding registrants that file electronically with the SEC. Such reports, proxy statements and other information may also be inspected at the offices of the New York Stock Exchange, Inc., on which MCN's common stock is traded, at 20 Broad Street, New York, New York 10005. MCN Investment and MCN have filed a Registration Statement on Form S-3 (together with all amendments and exhibits thereto, the "Registration Statement") with the SEC under the Securities Act of 1933, as amended (the "Securities Act") with respect to the Debt Securities. This Prospectus does not contain all of the information set forth in such Registration Statement, certain parts of which are omitted in accordance with the rules and regulations of the SEC. Reference is made to such Registration Statement and to the exhibits relating thereto for further information with respect to MCN Investment, MCN and the Debt Securities. Material provisions of the documents filed as exhibits to the Registration Statement or otherwise filed with the SEC or incorporated by reference are contained herein. Reference is made to the copy of such document so filed for a more complete description of the matter involved. MCN Investment will not file, as a separate registrant, the periodic reports required by Sections 13 and 15(d) of the 1934 Act because management has determined that separate financial statements of MCN Investment are not material to holders of the Debt Securities.

RATIO OF EARNINGS TO FIXED CHARGES The following table sets forth the ratio of earnings to fixed charges for the periods indicated. YEAR ENDED DECEMBER 31, -------------------------------------------- 1997 1996 1995 1994 1993 ---- ---- ---- ---- ---- MCN Investment(1)......................................... 1.46 1.28 1.24 1.29 1.55 MCN(1).................................................... 2.18 2.28 2.55 2.70 3.15 - ------------------------- (1) The Ratios of Earnings to Fixed Charges are based on earnings from operations. "Earnings" consist of the pre-tax income of majority-owned and 50%-owned companies adjusted to include any income actually received from less than 50% owned companies, plus fixed charges, less interest capitalized during the period for nonutility companies and less, in the case of MCN, the preferred stock dividend requirements of MichCon included in fixed charges but not deducted in the determination of pre-tax income. "Fixed Charges" represent (a) interest (whether expensed or capitalized), (b) amortization of debt discount, 3 20 premium and expense, (c) an estimate of interest implicit in rentals, and (d) in the case of MCN, the preferred securities dividend requirements of subsidiaries (MichCon, MCN Michigan Limited Partnership, MCN Financing I, MCN Financing III, MCN Financing V and MCN Financing VI), increased to reflect the pre-tax earnings requirement for MichCon. INTEREST COVERAGE RATIO The following table sets forth the interest coverage ratio for MCN Investment and MCN on a historical basis for the periods indicated. This ratio differs from the SEC prescribed "Ratio of Earnings to Fixed Charges" in its treatment of certain hybrid securities of MCN and MCNIC.

Income From Continuing Operations Before Income Taxes as reported on MCNIC's Consolidated Statement of Income has been adjusted to add (1) Interest Rate Charges as defined below and (2) intercompany interest expense. In addition, capitalized interest has been subtracted from Income From Continuing Operations Before Income Taxes. The computation of Interest Rate Charges includes interest expense as reported on MCNIC's Consolidated Statement of Income adjusted to add (1) capitalized interest expense and (2) interest implicit in rentals. In addition, intercompany interest expense and interest on the $130,000,000 of 6.82% Series Medium-Term Notes, issued in conjunction with the $135,000,000 of 8 3/4% Preferred Redeemable Increased Dividend Equity Securities of MCN, have been subtracted from interest expense. (2) The interest coverage ratio is the quotient of MCN's Income From Continuing Operations Before Income Taxes, as adjusted and defined below, divided by Interest Rate Charges as defined below. Income From Continuing Operations Before Income Taxes as reported on MCN's Consolidated Statement of Income has been adjusted to add the following: (1) Interest Rate Charges as defined below, (2) dividends on the $100,000,000 of 9 3/8% redeemable preferred securities of MCN Michigan Limited Partnership, (3) dividends on the $132,250,000 of 8% FELINE PRIDES of MCN Financing III, (4) interest on the $130,000,000 of 6.82% Series Medium-Term Notes issued in conjunction with the $135,000,000 of 8 3/4% Preferred Redeemable Increased Dividend Equity Securities of MCN, (5) dividends on the $80,000,000 of 8 5/8% Trust Originated Preferred Securities of MCN Financing I and (6) interest related to nonrecourse debt of MCN. In addition, capitalized interest, pension cost and postretirement benefit costs have been subtracted from the determination of Income From Continuing Operations Before Income Taxes. The computation of Interest Rate Charges includes total interest expense as reported on MCN's Consolidated Statement of Income adjusted to add: (1) capitalized interest expense, (2) dividends on the $100,000,000 of Single Point Remarketed Reset Capital Securities of MCN Financing VI, (3) dividends on the $100,000,000 of Private Institutional Trust Securities of MCN Financing V and (4) interest expense implicit in rentals.

DESCRIPTION OF DEBT SECURITIES The following description sets forth certain general terms and provisions of the Debt Securities to which any Prospectus Supplement may relate. The particular terms of the Debt Securities offered by any Prospectus Supplement and the extent, if any, to which such general provisions may apply to the Debt Securities so offered will be described in the Prospectus Supplement relating to such Debt Securities. The Debt Securities may be issued, from time to time, in one or more series. Debt Securities will be issued under an Indenture, dated as of September 1, 1995 (the "Indenture"), between the Company and NBD Bank ("NBD"), as trustee (the "Trustee"). NBD is a wholly-owned subsidiary of First Chicago NBD Corporation. A copy of the Indenture is incorporated by reference as an exhibit to this Registration Statement. The following summary contains material provisions of the Debt Securities and the Indenture. For a complete description of all the provisions of the Indenture, including the definitions therein of certain terms, reference is made to the Indenture incorporated by reference as an exhibit to this Registration Statement. Certain capitalized terms herein are defined in the Indenture. GENERAL The Debt Securities will be unsecured obligations of the Company. The Indenture does not limit the aggregate principal amount of Debt Securities which may be issued thereunder and provides that Debt Securities may be issued thereunder, from time to time, in one or more series. The Indenture does not contain any debt covenants or provisions which would afford bondholders protection in the event of a highly leveraged transaction. Reference is made to the Prospectus Supplement relating to the Debt Securities being offered (the "Offered Debt Securities") for, among other things, the following terms thereof: (1) the title of the Offered Debt Securities; (2) any limit on the aggregate principal amount of the Offered Debt Securities; (3) the date or dates on which the Offered Debt Securities will mature; (4) the rate or rates (which may be fixed or variable) per annum at which the Offered Debt Securities will bear interest or the method by which such rate or rates shall be determined and the date from which such interest will accrue or the method by which such date or dates shall be determined; (5) the dates on which such interest will be payable and the Regular Record Dates for such Interest Payment Dates; (6) the dates, if any, on which, and the price or prices at which, the Offered Debt Securities may, pursuant to any mandatory or optional sinking fund provisions, be redeemed by the Company and other detailed terms and provisions of such sinking funds; (7) the date, if any, after which, and the price or prices at which, the Offered Debt Securities may, pursuant to any optional redemption provisions, be redeemed at the option of the Company or of the Holder thereof and other detailed terms and provisions of such optional redemption; and (8) any other terms of the Offered Debt Securities (which terms shall not be inconsistent with the provisions of the Indenture). For a description of the terms of the Offered Debt Securities, reference must be made to both the Prospectus Supplement relating thereto and to the description of Debt Securities set forth herein. Unless otherwise indicated in the Prospectus Supplement relating thereto, the principal of, and any premium or interest on, the Offered Debt Securities will be payable, and the Offered Debt Securities will be exchangeable and transfers thereof will be registrable, at the Place of Payment, provided that, at the option of the Company, payment of interest may be made by check mailed, or wire transfer, to the address of the person entitled thereto as it appears in the Security Register. Unless otherwise indicated in the Prospectus Supplement relating thereto, the Offered Debt Securities will be issued in United States dollars in fully registered form, without coupons, in denominations of $1,000 or 5 22 any integral multiple thereof. No service charge will be made for any transfer or exchange of the Offered Debt Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. For purposes of the description of the Debt Securities, certain defined terms have the following meanings: "Indebtedness" of any Person means, without duplication, (i) the principal of and premium (if any) in respect of (A) indebtedness of such Person for money borrowed and (B) indebtedness evidenced by notes, debentures, bonds or other similar instruments for the payment of which such Person is responsible or liable; (ii) all Capitalized Lease Obligations of such Person; (iii) all obligations of such Person issued or assumed as the deferred purchase price of property, all conditional sale obligations and all obligations under any title retention agreement (but excluding trade accounts payable arising in the ordinary course of business); (iv) all obligations of such Person for the reimbursement of any obligor on any letter of credit, banker's acceptance or similar credit transaction (other than obligations with respect to letters of credit securing obligations (other than obligations described in (i) through (iii) above) entered into in the ordinary course of business of such Person to the extent such letters of credit are not drawn upon or, if and to the extent drawn upon, such drawing is reimbursed no later than the third Business Day following receipt by such Person of a demand for reimbursement following payment on the letter of credit); (v) all obligations of the type referred to in clauses (i) through (iv) of other Persons and all dividends of other Persons for the payment of which, in either case, such Person is responsible or liable as obligor, guarantor or otherwise; and (vi) all obligations of the type referred to in clauses (i) through (v) of other Persons secured by any Lien on any property or asset of such Person (whether or not such obligation is assumed by such Person), the amount of such obligation being deemed to be the lesser of the value of such property or assets or the amount of the obligation so secured. "Capitalized Lease Obligations" means an obligation under a lease that is required to be capitalized for financial reporting purposes in accordance with GAAP, and the amount of Indebtedness represented by such obligation shall be the capitalized amount of such obligation determined in accordance with such principles. "Project Finance Indebtedness" means Indebtedness of a Subsidiary (other than a Utility and other than the Company) secured by a Lien on any property, acquired, constructed or improved by such Subsidiary after the date of the Indenture which Lien is created or assumed contemporaneously with, or within 120 days after, such acquisition or completion of such construction or improvement, or within six months thereafter pursuant to a firm commitment for financing arranged with a lender or investor within such 120-day period, to secure or provide for the payment of all or any part of the purchase price of such property or the cost of such construction or improvement, or on any property existing at the time of acquisition thereof; provided that such a Lien shall not apply to any property theretofore owned by any such Subsidiary other than, in the case of any such construction or improvement, any theretofore unimproved real property on which the property so constructed or the improvement is located; and provided further that such Indebtedness, by its terms, shall limit the recourse of any holder of such Indebtedness (or trustee on such holder's behalf) in the event of any default in such Indebtedness to the assets subject to such Liens and the capital stock of the Subsidiary issuing such Indebtedness. Notwithstanding the foregoing, Project Finance Indebtedness shall include all Indebtedness that would constitute Project Finance Indebtedness but for the fact that such Indebtedness was issued prior to the date of the Indenture and taking into account the fact that the property subject to the Lien may have been acquired prior to the date of the Indenture. The Debt Securities may be issued under the Indenture as Original Issue Discount Securities to be offered and sold at a substantial discount below their principal amount. Special federal income tax, accounting and other considerations applicable to any such Original Issue Discount Securities will be described in any Prospectus Supplement relating thereto. "Original Issue Discount Security" means any security which provides for an amount less than the principal amount thereof to be due and payable upon a declaration of acceleration of the maturity thereof as a result of the occurrence of an Event of Default and the continuation thereof. 6 23 THE TRUSTEE NBD is the Trustee under the Indenture. NBD is also the Trustee under MCN's Senior and Subordinated Indentures. NBD has extended lines of credit to various subsidiaries of MCN. MCN and various of its subsidiaries maintain bank accounts and have other customary banking relationships with NBD in the ordinary course of business. In addition, various MCN subsidiaries, including MCN Investment borrow money from NBD. Mr. Thomas H. Jeffs II, President and Chief Operating Officer of NBD, serves as a Director of MCN. Mr. Alfred R. Glancy III, Chairman, President and Chief Executive Officer of MCN, serves as a Director of NBD. RESTRICTIONS The Indenture provides that neither the Company nor MCN shall consolidate with, merge with or into any other corporation (whether or not the Company or MCN, as the case may be, shall be the surviving corporation), or sell, assign, transfer or lease all or substantially all of its properties and assets as an entirety or substantially as an entirety to any Person or group of affiliated Persons, in one transaction or a series of related transactions, unless: (1) either the Company or MCN, as the case may be, shall be the continuing Person or the Person (if other than the Company or MCN) formed by such consolidation or with which or into which the Company or MCN is merged or the Person (or group of affiliated Persons) to which all or substantially all the properties and assets of the Company or MCN are sold, assigned, transferred or leased is a corporation (or constitute corporations) organized under the laws of the United States or any State thereof or the District of Columbia and expressly assumes, in the case of the Company, by an indenture supplemental to the Indenture, all the obligations of the Company under the Debt Securities and the Indenture, executed and delivered to the Trustee in form satisfactory to the Trustee; and in the case of MCN, the performance of every covenant of the Indenture on the part of MCN, as applicable, and all the obligations under the Support Agreement to be performed or observed; (2) immediately before and after giving effect to such transaction or series of transactions, no Event of Default, and no Default, with respect to the Debt Securities shall have occurred and be continuing; and (3) the Company or MCN, as applicable, shall have delivered to the Trustee an Officer's Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indentures comply with the Indenture. Each of the Company and MCN covenants and agrees in the Indenture that if, upon its consolidation with or merger into any other corporation, or upon any consolidation or merger of any other corporation with or into it, or upon any sale or conveyance of all or substantially all of its property and assets to any other corporation, any of its property or any property of any Subsidiary or any Indebtedness issued by any Subsidiary owned by it or by any other Subsidiary immediately prior thereto would thereupon become subject to any mortgage, security interest, pledge, lien or other encumbrance not permitted by the Indenture, prior to or concurrently with such consolidation, merger, sale or conveyance, it will effectively secure the Securities then Outstanding issued under the Indenture (equally and ratably with (or prior to) any other Indebtedness of or guaranteed by it or such Subsidiary then entitled thereto) by a direct lien, on such of its property or such property of a Subsidiary or such other Indebtedness issued by a Subsidiary, prior to all liens other than any theretofore existing thereon. The Indenture also provides that neither the Company nor MCN will, nor will MCN permit any Significant Subsidiary to, create, incur, or suffer to exist any Lien in, of or on the property of the Company, MCN or any of their Subsidiaries, except: (i) Liens for taxes, assessments or governmental charges or levies on its property if the same shall not at the time be delinquent or thereafter can be paid without penalty, or are being contested in good faith and by appropriate proceedings and for which adequate reserves in accordance with generally accepted principles of accounting shall have been set aside on its books; (ii) Liens imposed by law, such as carriers', warehousemen's and mechanics' liens and other similar liens arising in the ordinary course of business which secure payment of obligations not more than 60 days past due or which are being contested in good faith by appropriate proceedings and for which adequate reserves shall have been set aside on its books; (iii) Liens arising out of pledges or deposits under worker's compensation laws, unemployment insurance, old age pensions, or other social security or retirement benefits, or similar legislation; (iv) utility easements, building restrictions and such other encumbrances or charges against real property as are of a nature generally existing with respect to properties of a similar character and which do not in any material way 7 24 affect the marketability of the same or interfere with the use thereof in the business of the Company, MCN or their Subsidiaries, as the case may be; (v) Liens on the capital stock, partnership interest, or other evidence of ownership of any Subsidiary or such Subsidiary's assets that secure Project Finance Indebtedness for such Subsidiary; (vi) Liens arising in connection with first mortgage bonds issued by any Significant Subsidiary pursuant to any first mortgage indenture in effect as of the date of the Indenture, as such indenture may be supplemented from time to time; (vii) purchase money liens upon or in property now owned or hereafter acquired in the ordinary course of business (consistent with the Company's or MCN's business practices, as the case may be) to secure (A) the purchase price of such property or (B) Indebtedness incurred solely for the purpose of financing the acquisition, construction, or improvement of any such property to be subject to such liens, or Liens existing on any such property at the time of acquisition, or extensions, renewals, or replacements of any of the foregoing for the same or a lesser amount; provided that no such lien shall extend to or cover any property other than the property being acquired, constructed, or improved and replacements, modifications, and proceeds of such property, and no such extension, renewal, or replacement shall extend to or cover any property not theretofore subject to the Lien being extended, renewed, or replaced; (viii) Liens existing on the date Debt Securities are first issued; and (ix) Liens for no more than 90 days arising from a transaction involving accounts receivable of the Company or MCN, as the case may be (including the sale of such accounts receivable), where such accounts receivable arose in the ordinary course of the Company's or MCN's business, as the case may be. The Indenture provides that neither the Company nor MCN will, nor will they permit any Subsidiary to, enter into any arrangement with any lender or investor (other than the Company, MCN or a Subsidiary), or to which such lender or investor (other than the Company, MCN or a Subsidiary) is a party, providing for the leasing by the Company, MCN or such Subsidiary for a period, including renewals, in excess of three years of any real property located within the United States which has been owned by the Company, MCN or such Subsidiary, as the case may be, for more than six months and which has been or is to be sold or transferred by the Company, MCN or such Subsidiary, as the case may be, to such lender or investor or to any person to whom funds have been or are to be advanced by such lender or investor on the security of such real property unless either (a) the Company, MCN or such Subsidiary, as the case may be, could create Indebtedness secured by a lien consistent with the restrictions set forth in the foregoing paragraph on the real property to be leased in an amount equal to the Value of such transaction without equally and ratably securing the Debt Securities or (b) the Company or MCN, as the case may be, within six months after the sale or transfer shall have been made, applies an amount equal to the greater of (i) the net proceeds of the sale of the real property leased pursuant to such arrangement or (ii) the fair market value of the real property so leased to the retirement of Debt Securities and other obligations of the Company or MCN, as the case may be, ranking on a parity with the Debt Securities. Debt Securities rank pari passu with other unsecured indebtedness. EVENTS OF DEFAULT AND NOTICE THEREOF The following are Events of Default under the Indenture with respect to Debt Securities of any series: (1) failure to pay interest on any Debt Security of that series when due and payable, continued for 30 days; (2) failure to pay the principal of (or premium, if any, on) any Debt Security of that series when due and payable at Maturity, upon redemption or otherwise; (3) failure to observe or perform any other covenant, warranty or agreement of the Company or MCN contained in the Debt Securities of that series, the Indenture or the Support Agreement (other than a covenant, agreement or warranty included in the Indenture solely for the benefit of Debt Securities other than that series), continued for a period of 60 days after notice has been given to the Company by the Trustee or Holders of at least 25% in aggregate principal amount of the Outstanding Debt Securities of that series; (4) failure to pay at final maturity, or acceleration of, Indebtedness of the Company, MCN or a Subsidiary (but excluding Project Finance Indebtedness and certain other gas and oil reserve-based financing with limited recourse to MCN as described below) having an aggregate principal amount of more than 1% of the consolidated total assets of MCN (determined as of its most recent fiscal year-end), unless cured within 10 days after notice has been given to the Company by the Trustee or Holders of at least 10% in aggregate principal amount of the Outstanding Debt Securities of that series; (5) certain events of bankruptcy, insolvency or reorganization relating to the Company, MCN or a Significant Subsidiary; and (6) any other Event of Default with respect to Debt Securities of that series specified in the 8 25 Prospectus Supplement relating thereto or Supplemental Indenture under which such series of Debt Securities is issued. As noted in (4) above, it will not be an Event of Default under the Indenture if a default occurs in certain gas and oil reserve-based financing of MCNIC Oil & Gas Company (formerly known as Supply Development Group, Inc., a Subsidiary of the Company) or its Subsidiaries if the obligations of MCN and its Subsidiaries with respect to such Indebtedness (other than Supply Development Group, Inc. and its Subsidiaries) are limited to (i) payments with respect to Section 29 tax credits, (ii) payments with respect to certain material contracts of the borrower (generally limited to gas and oil supply contracts and gas and oil hedging contracts) and (iii) certain environmental obligations of the borrowers. As of December 31, 1997, $100,000,000 of such gas and oil reserve-based Indebtedness was outstanding. From time to time, MCN or its Subsidiaries may establish additional similar reserve-based credit facilities with respect to which a default would not result in an Event of Default under the Indenture. The Indenture provides that the Trustee shall, within 30 days after the occurrence of any Default or Event of Default with respect to Debt Securities of any series, give the Holders of Debt Securities of that series notice of all uncured Defaults or Events of Default known to it (the term "Default" includes any event which after notice or passage of time or both would be an Event of Default); provided, however, that, except in the case of an Event of Default or a Default in payment on any Debt Securities of any series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or directors or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders of Debt Securities of that series. If an Event of Default with respect to Debt Securities of any series (other than due to events of bankruptcy, insolvency or reorganization) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding Debt Securities of that series, by notice in writing to the Company (and to the Trustee if given by the Holders of at least 25% in aggregate principal amount of the Outstanding Debt Securities of that series), may declare the unpaid principal of and accrued interest to the date of acceleration on all the Outstanding Debt Securities of that series to be due and payable immediately and, upon any such declaration, the Outstanding Debt Securities of that series shall become immediately due and payable. If an Event of Default occurs due to bankruptcy, insolvency or reorganization, all unpaid principal of and accrued interest on the Outstanding Debt Securities of any series will become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of any Debt Security of that series. The Indenture provides that the Company shall periodically file statements with the Trustee regarding compliance by the Company with certain of the respective covenants thereof and shall specify any Event of Default or Defaults with respect to Debt Securities of any series, in performing such covenants, of which the signers may have knowledge. MODIFICATION OF INDENTURE; WAIVER The Indenture may be modified by the Company and the Trustee without the consent of any Holders with respect to certain matters, including (i) to cure any ambiguity, defect or inconsistency or to correct or supplement any provision which may be inconsistent with any other provision of the Indenture and (ii) to make any change that does not materially adversely affect the interests of any Holder of Debt Securities of any series. In addition, under the Indenture, certain rights and obligations of the Company and the rights of Holders of the Debt Securities may be modified by the Company and the Trustee with the written consent of the Holders of at least a majority in aggregate principal amount of the Outstanding Debt Securities of each series affected thereby; but no extension of the maturity of any Debt Securities of any series, reduction in the interest rate or extension of the time for payment of interest, change in the optional redemption or repurchase provisions in a manner adverse to any Holder of Debt Securities of any series, other modification in the terms of payment of the principal of, or interest on, any Debt Securities of any series, or reduction of the percentage required for modification, will be effective against any Holder of any Outstanding Debt Security of any series 9 26 affected thereby without the Holder's consent. The Indenture does not limit the aggregate amount of Debt Securities of the Company which may be issued thereunder. The Holders of a majority in aggregate principal amount of the Outstanding Debt Securities of any series may on behalf of the Holders of all Debt Securities of that series waive, insofar as that series is concerned, compliance by the Company with certain restrictive covenants of the Indenture. The Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of any series may on behalf of the Holders of all Debt Securities of that series waive any past Event of Default or Default under the Indenture with respect to that series, except an Event of Default or a Default in the payment of the principal of, or premium, if any, or any interest on any Debt Security of that series or in respect of a provision which under the Indenture cannot be modified or amended without the consent of the Holder of each Outstanding Debt Security of that series affected. DEFEASANCE The Company may terminate its substantive obligations in respect of Debt Securities of any series (except for its obligations to pay the principal of (and premium, if any, on) and the interest on the Debt Securities of that series) by (i) depositing with the Trustee, under the terms of an irrevocable trust agreement, money or U.S. Government Obligations sufficient to pay all remaining indebtedness on the Debt Securities of that series, (ii) delivering to the Trustee either an Opinion of Counsel or a ruling directed to the Trustee from the Internal Revenue Service to the effect that the Holders of the Debt Securities of that series will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and termination of obligations, and (iii) complying with certain other requirements set forth in the Indenture. BOOK-ENTRY DEBT SECURITIES The Debt Securities of a series may be issued in whole or in part in the form of one or more Global Securities (as such term is defined below) that will be deposited with, or on behalf of, a Depositary ("Depositary") or its nominee identified in the applicable Prospectus Supplement. In such a case, one or more Global Securities will be issued in a denomination or aggregate denomination equal to the portion of the aggregate principal amount of outstanding Debt Securities of the series to be represented by such Global Security or Global Securities. Unless and until it is exchanged in whole or in part for Debt Securities in registered form, a Global Security may not be registered for transfer or exchange except as a whole by the Depositary for such Global Security to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any nominee to a successor Depositary or a nominee of such successor Depositary and except in the circumstances described in the applicable Prospectus Supplement. The term "Global Security", when used with respect to any series of Debt Securities, means a Debt Security that is executed by the Company and authenticated and delivered by the Trustee to the Depositary or pursuant to the Depositary's instruction, which shall be registered in the name of the Depositary or its nominee and which shall represent, and shall be denominated in an amount equal to the aggregate principal amount of, all of the outstanding Debt Securities of such series or any portion thereof, in either case having the same terms, including, without limitation, the same original issue date, date or dates on which principal is due, and interest rate or method of determining interest. The specific terms of the depositary arrangement with respect to any portion of a series of Debt Securities to be represented by a Global Security will be described in the applicable Prospectus Supplement. The Company expects that the following provisions will apply to depositary arrangements. Unless otherwise specified in the applicable Prospectus Supplement, Debt Securities which are to be represented by a Global Security to be deposited with or on behalf of a Depositary will be represented by a Global Security registered in the name of such Depositary or its nominee. Upon the issuance of such Global Security, and the deposit of such Global Security with or on behalf of the Depositary for such Global Security, the Depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of the Debt Securities represented by such Global Security to the accounts of institutions that have accounts with such Depositary or its nominee ("participants"). The accounts to be credited will be designated by the 10 27 underwriters or agents of such Debt Securities or, if such Debt Securities are offered and sold directly by the Company, by the Company.

The Support Agreement also provides that any Lender to the Company shall have the right to demand that the Company enforce its rights against MCN under the Support Agreement as described in the previous sentence, and in the event that the Company fails to require MCN to perform such obligations or the Company defaults in the timely payment of principal of, or any premium or interest on, any Debt owed to a Lender, such Lender may proceed directly against MCN to enforce the Company's rights against MCN under the Support Agreement or to obtain payment of such defaulted principal, premium or interest owed to such Lender. The Support Agreement provides that in no event may any Lender, on default of the Company or MCN or upon failure by the Company or MCN to comply with the Support Agreement, have recourse to or against the stock or assets of MichCon, or any interest of the Company or MCN therein. Notwithstanding this limitation, the Support Agreement provides that funds available to MCN to satisfy any obligations under the Support Agreement will include cash dividends paid by MichCon to MCN. In addition to the cash dividends paid to MCN by any of its subsidiaries, the assets of MCN other than the stock and assets of MichCon are available as recourse to holders of the Company's Debt. The carrying value of such assets reflected in MCN's 11 28 balance sheet on an unconsolidated basis, at September 30, 1997 is approximately $1.1 billion. The term "Debt" is defined in the Support Agreement as debt securities or other obligations, and includes the Debt Securities. The term "Lender" is defined in the Support Agreement as any person, firm, corporation or other entity to which the Company is indebted for money borrowed or to which the Company otherwise owes any Debt or which is acting as trustee or authorized representative on behalf of such person, firm, corporation or other entity. The Indenture provides that each Holder of a Debt Security, as well as the Trustee, shall be considered a "Lender" for purposes of the Support Agreement. Funds to repay the Debt Securities at maturity pursuant to the Support Agreement would come from earnings in the form of dividends paid to MCN by MichCon and MCN's other subsidiaries, the earnings of other businesses of MCN and its subsidiaries, or the proceeds of financing transactions. The Support Agreement provides that MCN will not take any action (or refrain from taking any action) to the extent that such action or inaction would cause a default in the performance or breach of any term or provision of the Indenture, or any Debt outstanding under the Indenture, and MCN will comply with all covenants and provisions of the Indenture applicable to it as if it were a party to the Indenture. The Support Agreement may be amended or terminated at any time by agreement of MCN and the Company, provided that (i) no amendment regarding the terms described above may be made unless all Lenders consent in advance and in writing to such amendment, (ii) no amendment regarding any other term of the Support Agreement may be made in a manner that adversely affects the rights of Lenders unless all affected Lenders consent in advance and in writing to such amendment and (iii) no termination shall be effective until such time as all Debt (including the Debt Securities) shall have been paid in full.
