MANAGEMENT’S NARRATIVE ANALYSIS OF THE RESULTS OF OPERATIONS

The Results of Operations discussion for MichCon is presented in accordance with General Instruction H(2)(a) of Form 10-Q.

MichCon reported earnings of $69 million for the first quarter of 2004 compared to earnings of $75 million for the 2003 first quarter. Results for the first quarter of 2004 were primarily impacted by increases in operation and maintenance expenses due to higher uncollectible accounts expense offset by a lower effective tax rate.

Operating revenues increased $63 million in the first quarter of 2004, reflecting increased gas sales and reduced end user transportation revenues.

Gas sales and end user transportation revenues in total increased $64 million in the first quarter of 2004. The increase is due primarily to an increase in Gas Cost Recovery (GCR) revenues of $73 million for the first quarter of 2004. This portion of revenues is offset by similar gas costs subject to collection through the GCR. End user transportation revenues for the three-month period reflect lower volumes for deliveries associated with a varying number of customers participating in the Customer Choice program. Customers participating in this program purchase gas from suppliers other than MichCon, while MichCon continues to deliver the gas to their premises. Accordingly, margins earned from selling gas and margins generated from providing end user transportation services to Customer Choice participants are the same. There were approximately 119,000 customers participating in the Customer Choice program at March 31, 2004, compared with approximately 129,000 customers at December 31, 2003.

Cost of gas is affected by variations in sales volumes, cost of purchased gas and related transportation costs. Cost of gas sold increased by $67 million in the first quarter of 2004. The average cost of gas sold increased $.71 per Mcf (14%) for the first quarter from the comparable 2003 period.

Operation and maintenance expenses increased $18 million for the 2004 first quarter from the comparable 2003 period primarily due to higher uncollectible accounts expense, reflecting higher past due amounts attributable to current economic conditions.

Income taxes decreased $15 million for the 2004 first quarter due to a lower effective tax rate in 2004 driven by lower estimated annual earnings.

MICHIGAN CONSOLIDATED GAS COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 — GENERAL

These consolidated financial statements should be read in conjunction with the notes to the consolidated financial statements included in our 2003 Annual Report on Form 10-K.

The accompanying consolidated financial statements are prepared using accounting principles generally accepted in the United States of America. These accounting principles require us to use estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

The consolidated financial statements are unaudited, but in our opinion, include all adjustments necessary for a fair statement of the results for the interim periods. Financial results for this interim period are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year.

We reclassified some prior year balances to match the current year’s presentation.

Retirement Benefits and Trusteed Assets

The MCN Energy Group Retirement Plan, that covered nonrepresented employees, merged into the DTE Energy Company Retirement Plan. Detroit Edison operates as the sponsor of the merged DTE Energy represented and nonrepresented plan, which is treated as a plan covering employees of various affiliates of DTE Energy from the affiliates’ perspective. We are allocated income or an expense each year as a result of our participation in the DTE Energy Retirement Plan. Income was approximately $7 million and $8 million for the three months ended March 31, 2004 and 2003, respectively and is not reflected in the table below.

The components of net periodic benefit costs for qualified and non-qualified pension benefits and other postretirement benefits follow:

NOTE 2 — REGULATORY MATTERS

Gas Rate Plan

Rate Request — In September 2003, MichCon filed an application with the MPSC for an increase in service and distribution charges (base rates) for its gas sales and transportation customers. The filing requests an overall increase in base rates of $194 million per year (approximately 7% increase, inclusive of gas costs), beginning January 1, 2005. MichCon has requested that the MPSC increase base rates by $154 million per year on an interim basis by April 1, 2004. The interim request is based on a projected revenue deficiency for the test year 2004.

MPSC Staff Report on Interim Rate Relief — The MPSC Staff report on MichCon’s interim rate request was filed on May 3, 2004. After adjusting for several items that it will address in its final rate relief recommendation, the MPSC Staff recommended a $25 million interim rate increase. This compares with MichCon’s requested total interim base rate relief of $154 million. In addition, the MPSC Staff proposed a 50% debt and 50% equity capital structure utilizing MichCon's current allowed rate of return of 11.5%. An interim order is expected in the third quarter of 2004 and a final order in the first quarter of 2005.

Gas Cost Recovery Proceedings

2002 Plan Year — In December 2001, the MPSC issued an order that permitted MichCon to implement GCR factors up to $3.62 per Mcf for January 2002 billings and up to $4.38 per Mcf for the remainder of 2002. The order also allowed MichCon to recognize a regulatory asset of approximately $14 million representing the difference between the $4.38 factor and the $3.62 factor for volumes that were unbilled at December 31, 2001. The regulatory asset is subject to the 2002 GCR reconciliation process. In March 2003, the MPSC issued an order in MichCon’s 2002 GCR plan case. The MPSC ordered MichCon to reduce its gas cost recovery expenses by $26.5 million for purposes of calculating the 2002 GCR factor due to MichCon’s decision to utilize storage gas during 2001 that resulted in a gas inventory decrement for the 2001 calendar year.

Although we recorded a $26.5 million reserve in 2002 to reflect the impact of this order, a final determination of actual 2002 revenue and expenses including any disallowances or adjustment will be decided in MichCon’s 2002 GCR reconciliation case that was filed with the MPSC in February 2003. The MPSC Staff and various intervening parties in this proceeding are seeking to have the MPSC disallow an additional $26 million, representing unbilled revenues at December 2001. One party has proposed that half of the $8 million related to the settlement of the Enron bankruptcy also be disallowed. The other parties to the case have recommended that the Enron bankruptcy settlement be addressed in the 2003 GCR reconciliation case. An MPSC administrative law judge has recommended disallowances of $26.5 million related to the use of storage gas in 2001 and $26 million related to the December 2001 unbilled issue, and recommended that the $8 million related to the Enron issue be addressed in the 2003 GCR reconciliation case. We have included this item in our testimony in the 2003 GCR reconciliation filed in February 2004. A final order in this proceeding is expected in 2004. In addition, we filed an appeal of the March 2003 MPSC order with the Michigan Court of Appeals.

2003 Plan Year — In July 2003, the MPSC approved an increase in MichCon’s 2003 GCR rate to a maximum of $5.75 per Mcf for the billing months of August 2003 through December 2003. As of December 31, 2003, MichCon has accrued a $19 million regulatory asset representing the under-recovery of actual gas costs incurred.

2004 Plan Year — In September 2003, MichCon filed its 2004 GCR plan case proposing a maximum GCR factor of $5.36 per Mcf. MichCon agreed to switch from a calendar year to an

13

operational year as a condition of its settlement in the 2003 GCR Plan Case. The operational GCR year would run from April to March of the following year. To accomplish the switch, the 2004 GCR Plan Case reflects a 15-month transitional period, January 2004 through March 2005. Under the transition proposal, MichCon would file two reconciliations pertaining to the transition period; one addressing the January 2004 to March 2004 period, the other addressing the remaining April 2004 to March 2005 period. The plan also proposes a quarterly GCR ceiling price adjustment mechanism. This mechanism allows MichCon to increase the maximum GCR factor to compensate for increases in market prices thereby minimizing the possibility of a GCR under recovery. Due to sustained increase in market prices for natural gas, in March 2004, MichCon filed updated GCR testimony requesting an increased maximum GCR factor of $6.15 per Mcf.

We are unable to predict the outcome of the regulatory matters discussed herein. Resolution of these matters is dependent upon future MPSC orders, which may materially impact our financial position, results of operations and cash flows.

NOTE 3 — CONTINGENCIES

We are involved in certain legal, regulatory and administrative proceedings before various courts, arbitration panels and governmental agencies concerning claims arising in the ordinary course of business. These proceedings include certain contract disputes, environmental reviews and investigations, audits, inquiries from various regulators, and pending judicial matters. We cannot predict the final disposition of such proceedings. We regularly review legal matters and record provisions for claims that are considered probable of loss. The resolution of pending proceedings is not expected to have a material effect on our financial statements in the period they are resolved.

See Note 2 for a discussion of contingencies related to Regulatory Matters.

INDEPENDENT ACCOUNTANTS’ REPORT

To the Board of Directors and Shareholder of
Michigan Consolidated Gas Company

We have reviewed the accompanying condensed consolidated statement of financial position of Michigan Consolidated Gas Company and subsidiaries as of March 31, 2004, and the related condensed consolidated statements of operations, cash flows and retained earnings for the three-month periods ended March 31, 2004 and 2003, respectively. These interim financial statements are the responsibility of Michigan Consolidated Gas Company’s management.

We conducted our review in accordance with standards established by the American Institute of Certified Public Accountants. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with auditing standards generally accepted in the United States of America, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to such condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with auditing standards generally accepted in the United States of America, the consolidated statement of financial position of Michigan Consolidated Gas Company and subsidiaries as of December 31, 2003, and the related consolidated statements of operations, cash flows and retained earnings for the year then ended (not presented herein); and in our report dated March 1, 2004 (which report includes an explanatory paragraph relating to the change in the method of accounting for asset retirement obligations in 2003), we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated statement of financial position as of December 31, 2003 is fairly stated, in all material respects, in relation to the consolidated statement of financial position from which it has been derived.
