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 net income of $74.7 million for the first quarter of 2003 compared to net income of $54.1 million in the 2002 first quarter. The increase was primarily due to higher weather related demand and a lower effective tax rate partially, offset by increased operation and maintenance cost.

Increase (Decrease) in Income Compared to Prior Year
(in Millions)
Operating revenues	$	61.6
Cost of gas		(36.6	)
Gross margin		25.0
Operation and maintenance		(11.9	)
Depreciation, depletion and amortization		1.3
Other (income) and deductions		1.2
Income tax provision		5.0
Net income	$	20.6

Operating revenues increased $61.6 million in the first quarter of 2003, reflecting increased contributions from weather related sales and higher Gas Cost Recovery (GCR) revenues.

	Quarter
Gas Markets (in Millions)	2003		2002
Gas Sales	$	561.1	$	526.3
End User Transportation		57.2		31.6

Intermediate Transportation		13.4		12.1

		140.8		124.4
Intermediate Transportation		174.5		137.3
		315.3		261.7

4

Gas sales and end user transportation revenues in total increased $60.4 million in the 2003 first quarter due primarily to $27.7 million in weather related demand and an associated increase of $31.5 million in Gas Cost Recovery (GCR) revenues. Upon returning to the GCR mechanism in January 2002, MichCon has no commodity price risk associated with its prudently incurred gas costs. End user transportation volumes and revenues also reflect 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 customers are the same.

Intermediate transportation revenues increased $1.3 million in the 2003 first quarter and intermediate transportation deliveries increased 37.2 billion cubic feet (Bcf) for the same period. A significant portion of the volume increase was due to increased weather demand and storage requirements combined with a volume increase attributable to customers who pay a fixed fee for intermediate transportation capacity regardless of actual usage. Although volumes associated with these fixed-fee customers may vary, the related revenues are not affected.

Cost of gas is affected by variations in sales volumes, cost of purchased gas and related transportation costs, and the effects of any permanent liquidation of inventory gas. Cost of gas sold increased by $36.6 million in the first quarter of 2003. The increase was due primarily to increased volumes due to colder weather in 2003. The average cost of gas sold increased $.19 per Mcf (3.9%) from the comparable 2002 period.

Operation and maintenance expenses increased $11.9 million for the 2003 first quarter compared to the same period in 2002 due to higher employee pension and health care benefit costs and increased costs associated with customer service process improvements. As a result of the continued increase in operating costs, MichCon expects to file a rate case in the latter half of 2003.

Other income and deductions decreased $1.2 million in the 2003 first quarter primarily due to lower interest expense associated with long term debt.

Income taxes decreased $5.0 million for the 2003 first quarter compared to the same period in 2002. The income tax provision was favorably affected by an increase in the amortization of tax benefits previously deferred in accordance with MPSC regulations.

Operating Activities

Net cash from operating activities increased $143 million due to increases in net income, utilization of gas in inventory and gas inventory equalization and a decrease in unbilled revenues, offset by increases in accounts receivable due to higher volumes.

Investing Activities

Net cash used for investing activities increased $268 million reflecting an increase in intercompany loans to DTE Energy, resulting from temporary excess cash.

Financing Activities

Net cash related to financing activities increased $124 million reflecting the issuance of $200 million in debt, partially offset by a reduction in short term borrowings, retirement of long-term debt and the payment of a dividend in the first quarter of 2003.

CONTROLS AND PROCEDURES

(a)	Evaluation of disclosure controls and procedures
	MichCon’s Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of MichCon’s disclosure controls and procedures (as defined in Exchange Act Rules 13a — 14(c) and 15d — 14(d)) as of a date within 90 days before the filing of this quarterly report, and have concluded that, as of the evaluation date, such controls and procedures were effective at ensuring that required information will be disclosed on a timely basis in reports filed under the Exchange Act.
(b)	Changes in internal controls
	There have been no significant changes (including corrective actions with regard to significant deficiencies or material weaknesses) in MichCon’s internal controls or in other factors that could significantly affect these controls subsequent to the evaluation date referenced in paragraph (a) above.

MICHIGAN CONSOLIDATED GAS COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — GENERAL

These consolidated financial statements should be read in conjunction with the notes to the consolidated financial statements included in our 2002 Annual Report to the Securities and Exchange Commission 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.

NOTE 2 — NEW ACCOUNTING PRONOUNCEMENTS

Asset Retirement Obligations

On January 1, 2003, we adopted SFAS No. 143, “Accounting for Asset Retirement Obligations,” which requires the fair value of an asset retirement obligation be recognized in the period in which it is incurred. It applies to legal obligations associated with the retirement of long-lived assets resulting from the acquisition, construction, development and (or) the normal operation of a long-lived asset. When a new liability is recorded, an entity capitalizes the costs of the liability by increasing the carrying amount of the related long-lived asset. The liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity settles the obligation for its recorded amount or incurs a gain or loss upon settlement. The adoption of SFAS No. 143 had an immaterial impact on the consolidated financial statements.

SFAS No. 143 also requires the quantification of the estimated cost of removal obligations, arising from other than legal obligations, which have been accrued through depreciation charges. At January 1, 2003 we estimated that we had approximately $400 million of previously accrued asset removal costs related to our regulated operations, for other than legal obligations, included in accumulated depreciation.

NOTE 3 — REGULATORY MATTERS

Gas Industry Restructuring

Through December 2001, MichCon was operating under an MPSC-approved Regulatory

12

Reform Plan, which included a comprehensive experimental three-year gas Customer Choice program, a Gas Sales Program and an income sharing mechanism. MichCon returned to a GCR mechanism in January 2002 when the Gas Sales Program expired. Under the GCR mechanism, the gas commodity component of MichCon’s gas sales rates is designed to recover the actual costs of gas purchases. 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 will be subject to the 2002 GCR reconciliation process. As of December 31, 2002, MichCon has accrued a $22 million regulatory asset representing the under-recovery of actual gas costs incurred. In July 2002, in response to a petition for rehearing filed by the Michigan Attorney General, the MPSC directed the parties to address MichCon’s implementation of the December 2001 order and the impact of that implementation on rates charged to MichCon’s customers. On March 12, 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 MichCon 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. In addition, we filed an appeal of the March 12, 2003 MPSC order with the Michigan Court of Appeals.

In December 2001, the MPSC also approved MichCon’s application for a voluntary, expanded permanent gas Customer Choice program, which replaced the experimental program that expired in March 2002. Effective April 2002, up to 40% of MichCon’s customers could elect to purchase gas from suppliers other than MichCon. Effective April 2003, up to 60% of customers are eligible and by April 2004, all of MichCon’s 1.2 million customers can participate in the program. The MPSC also approved the use of deferred accounting for the recovery of implementation costs of the gas Customer Choice program. As of March 2003, approximately 160,000 customers are participating in the gas Customer Choice program.

NOTE 4 — LONG TERM DEBT

In February 2003, MichCon issued $200 million of 5.7% senior notes due in March 2033. The proceeds were used for debt redemption and general corporate purposes.

NOTE 5 — CONTINGENCIES

We are involved in certain legal (including commercial matters), administrative and environmental 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, 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 3 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, 2003, and the related condensed consolidated statements of operations, cash flows, and retained earnings for the three-month periods ended March 31, 2003 and 2002. These 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 to financial data and of 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 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, 2002, 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 February 11, 2003 (March 12, 2003 as to Note 17), 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, 2002 is fairly stated, in all material respects, in relation to the consolidated statement of financial position from which it has been derived.
