Management’s Narrative Analysis of the Results of Operations

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

Detroit Edison reported net income of $105 million for the 2002 three-month period, compared to net income of $88 million for the same period in 2001. For the nine-month period, net income was $272 million compared to $124 million for the same period in 2001. The earnings comparability for the three- and nine-month periods is affected by $9 million ($5 million net of tax) and $184 million ($119 million net of tax), respectively, of merger and restructuring charges that were recorded in 2001.

New reporting alignment - Beginning in 2002, Detroit Edison’s parent company, DTE Energy, realigned its internal and external financial reporting structure into three strategic business units (Energy Resources, Energy Distribution and Energy Gas) that have both regulated and non-regulated operations. Based on this structure, management sets strategic goals, allocates resources and evaluates performance. The realignment resulted in the following two reportable segments for Detroit Edison:

Energy Resources includes the power generation services of Detroit Edison. Electricity is generated from Detroit Edison’s numerous fossil plants or its nuclear plant and sold throughout Southeastern Michigan to residential, commercial, industrial and wholesale customers.

Energy Distribution includes the electric distribution services of Detroit Edison. Energy Distribution distributes electricity generated by Energy Resources and alternative electric suppliers to Detroit Edison’s 2.1 million residential, commercial and industrial customers.

Energy Resources

Earnings increased $8 million and $30 million during the 2002 three- and nine-month periods, respectively, reflecting higher gross margins due to lower purchased power costs. The lower purchased power costs reflect favorable energy market prices in 2002. Mark to market accounting for forward and option contracts in 2001 impacted revenues and purchased power, resulting in a favorable impact on margins of $36 million in the 2001 third quarter, and an unfavorable impact on margins of $9 million in the 2001 nine-month period. Margins were also impacted by higher revenues due to greater cooling demand in the 2002 third quarter and the loss of revenues resulting from customers switching to alternative electric suppliers under the electric Customer Choice program. Revenues for the 2002 nine-month period also were reduced due to the impact of a 5% legislatively mandated, securitization based, rate reduction for commercial and industrial customers that began in April 2001. The higher gross margins were partially offset by increased employee benefit costs and higher operations and maintenance expenses due to planned and unplanned reliability and maintenance work done to improve the production and availability of the generation fleet. Depreciation and amortization expense decreased in the nine-month period reflecting the extension of the amortization period from 7 years to 15 years for certain regulatory assets that were securitized in 2001.

Outlook -Electric restructuring will continue to result in increased competition in the electric generation business. Effective January 1, 2002, the electric Customer Choice program in Michigan was expanded to allow all electric customers to choose to purchase their electricity from suppliers other than their local utility. Detroit Edison expects to lose between 5% to 8% of retail sales in 2002 and between 10% to 15% of such sales in 2003 as a result of customers choosing to participate in the electric Customer Choice program. To the extent Detroit Edison experiences net stranded costs as a result of customers switching to an alternative electric supplier, Michigan law allows the recovery of all amounts of such net stranded costs. Detroit Edison disagreed with the MPSC initial methodology for determining and recovering net stranded costs and has asked for rehearing, clarification and modification of the December 2001 order. In May 2002, the MPSC denied Detroit Edison’s request for rehearing and clarification on certain aspects of the order. In June 2002, Detroit Edison filed a claim of appeal of the December 2001 MPSC order with the Michigan Court of Appeals.

In May 2002, Detroit Edison filed a new net stranded cost case with the MPSC that seeks to refine the methodology approved by the MPSC in December 2001 and calculates actual net stranded costs for 2000 and 2001. The MPSC Staff and interveners submitted their net stranded cost filings in November 2002. Detroit Edison expects to record 2002 net stranded costs as a regulatory asset with the offsetting entry reducing expense in the fourth quarter of 2002. See Note 3.

Energy Distribution

Earnings increased $4 million during the 2002 three-month period and decreased $1 million during the 2002 nine-month period reflecting higher operating revenues which were offset by increased operation and maintenance expenses. Operating revenues increased due primarily to higher residential sales attributable to greater cooling demand. The increased operation and maintenance expenses are attributable to heat-related maintenance expenses due to prolonged periods of above normal temperatures and the related stress placed on the distribution system, higher employee benefit costs, and expenses associated with restoring power to customers who lost service during two storms in the 2002 nine-month period.

Outlook - Regulated electric system deliveries are expected to continue to increase for the remainder of 2002 and into 2003 due to the economic recovery. Operating results will vary as a result of various external factors such as weather, changes in economic conditions and the severity and frequency of storms.

Operating Activities

Net cash from operating activities decreased $193 million in the 2002 nine-month period compared to the same period in 2001. The decrease reflects a $45 million decline in net income, after adjusting for non-cash items (depreciation, depletion and amortization, merger and restructuring charges and deferred taxes), and higher working capital levels. The working capital requirements reflect lower accounts payable balances, to more normalized levels, representing the internal focus on managing external payments and taking greater advantage of purchase discounts.

Investing Activities

Net cash used for investing activities decreased $244 million in the 2002 nine-month period compared to the same period in 2001 due to lower investments in regulatory assets associated with securitizing the company’s Fermi 2 power generation facility in March 2001. Additionally, a significantly lower amount of cash that was restricted for debt redemptions also affected the comparison.

Financing Activities

Net cash used for financing activities increased $237 million during the 2002 nine-month period compared to the same period in 2001. This change is due primarily to the repurchase of more debt, net of issuances in the 2002 period. Additionally, the repurchase of $846 million in common stock in 2001 also contributed to the change.

PENSION AND POSTRETIREMENT COSTS

Detroit Edison’s costs of providing pension and postretirement benefits are dependent upon a number of factors, such as the rates of return on plan assets, the discount rate and the rate of increase in health care costs. The market value of plan assets has been affected by sharp declines in the equity market since 2000. As a result, at December 31, 2002, Detroit Edison could be required to recognize an additional minimum pension liability as prescribed by SFAS No. 87 “Employers’ Accounting for Pensions” and SFAS No. 132 “Employers’ Disclosures about Pensions and Postretirement Benefits.” The offset to any liability would be recorded as a reduction in shareholder’s equity, net of tax, or as a regulatory asset. The additional minimum pension liability and related accounting entries would be reversed on the balance sheet in future periods if the fair value of plan assets exceeds the accumulated pension benefit obligations. The additional minimum

Management’s Narrative Analysis and Results of Operations

pension liability recorded, if any, will depend upon actual returns and interest rates in 2002, but could exceed $300 million pre-tax ($195 million after tax). The recording of any minimum pension liability would not affect net income or cash flow in 2002. Pension and postretirement costs and pension cash funding requirements could increase in future years without a substantial recovery in the equity markets. It is estimated that the increase in 2003 pension and postretirement costs could range from $80 million-$110 million, pre-tax, depending on actual plan asset returns, the discount rate and other actuarial assumptions that will not be determined until December 31, 2002. Detroit Edison will initiate cost saving strategies to significantly offset the earnings impact of higher pension and postretirement costs.

ENVIRONMENTAL MATTERS

EPA ozone transport regulations and new air quality standards relating to ozone and particulate air pollution will impact the Company. Detroit Edison has spent approximately $409 million through September 2002 and estimates that it will incur an additional $400 to $450 million of future capital expenditures over the next five years to comply.

NEW ACCOUNTING PRONOUNCEMENTS

During 2001, the Financial Accounting Standards Board (FASB) issued new accounting pronouncements concerning business combinations, goodwill and other intangible assets, asset retirement obligations and impairment or disposal of long-lived assets. See Note 7 for a discussion of Detroit Edison’s evaluation of the adoption of these new accounting pronouncements.

The Detroit Edison Company
Notes to Consolidated Financial Statements (Unaudited)

NOTE 1 — GENERAL

These consolidated financial statements should be read in conjunction with the notes to consolidated financial statements included in the 2001 Annual Report to the Securities and Exchange Commission on Form 10-K.

The accompanying consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States of America. In connection with their preparation, management makes estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

The consolidated financial statements are unaudited, but in the opinion of the Company’s management, 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 results that may be expected for any other interim period or for the fiscal year.

Certain prior year balances have been reclassified to conform to the current year’s presentation.

NOTE 2 — MERGER AND RESTRUCTURING CHARGES

On May 31, 2001, Detroit Edison’s parent company, DTE Energy, completed the acquisition of MCN Energy. Detroit Edison incurred merger-related charges and restructuring charges associated with the acquisition. The merger-related charges of $7 million ($4 million after tax) in the 2001 three-month period and $19 million ($12 million after tax) in the 2001 nine-month period, consisted primarily of system integration, relocation, legal, accounting and consulting costs. Restructuring charges of $2 million ($1 million after tax) in the 2001 three-month period and $165 million ($107 million after tax) in the 2001 nine-month period, were primarily associated with a work force reduction plan. The plan included early retirement incentives along with voluntary separation arrangements for 890 employees, primarily in overlapping corporate support functions. The merger and restructuring costs had the effect of decreasing Detroit Edison’s earnings by $9 million ($5 million after tax) and $184 million ($119 million after tax) for the 2001 three- and nine-month periods, respectively.

NOTE 3 — REGULATORY MATTERS

Electric Industry Restructuring

As required by 2000 Public Act (PA) 141, the MPSC conducted a proceeding to develop a methodology for calculating the net stranded costs associated with electric Customer Choice. In a December 2001 order, the MPSC determined that Detroit Edison could recover net stranded costs associated with the fixed cost component of its electric generation operations. Specifically, there would be an annual filing with the MPSC comparing the actual revenues associated with the fixed cost component of its generation services to the revenue requirement for the fixed cost component of those services, inclusive of an allowance for the cost of capital. Any resulting shortfall in recovery, net of mitigation, would be considered a net stranded cost. The MPSC, in its December 2001 order, also determined that Detroit Edison had no stranded costs in 2000 and consequently established a zero net stranded cost transition charge for billing purposes in 2002. The MPSC

16


Table of Contents

Notes to Consolidated Financial Statements (Unaudited)

authorized Detroit Edison to establish a regulatory asset to defer recovery of its incurred stranded costs after review in a subsequent annual net stranded cost proceeding. The MPSC also determined that Detroit Edison should provide a full and offsetting credit for the securitization and tax charges applied to electric Customer Choice bills in 2002 and maintained an additional credit on bills equivalent to the 5% rate reduction benefiting full service customers, both funded by savings derived from securitization. The December 2001 order when combined with lower wholesale power prices has encouraged additional customer participation in the electric Customer Choice program and has resulted in the loss of margins attributable to generation services. In May 2002, the MPSC denied Detroit Edison’s request for rehearing and clarification. In June 2002, Detroit Edison filed an appeal of the MPSC order at the Michigan Court of Appeals, challenging the legality of specific aspects of the MPSC order.

In May 2002, Detroit Edison submitted its 2002 net stranded cost filing with the MPSC. The filing provides refinements to the MPSC Staff’s calculation of net stranded costs that was adopted in the December 2001 order, seeks more timely recovery of net stranded costs, and addresses issues raised by the continuation of securitization offsets and rate reduction equalization credits. Detroit Edison’s filing supports the following conclusions: (i) Detroit Edison had no net stranded costs in 2000 and $13 million of recoverable net stranded costs attributable to electric Customer Choice in 2001; (ii) Detroit Edison requested recovery of 2001 net stranded costs through the use of excess residual securitization savings; (iii) Detroit Edison expects to incur additional net stranded costs in 2002 and 2003 as a result of increased electric Customer Choice participation; and (iv) recommended that a pro-forma or forward looking transition charge be approved for billing during the remainder of 2002 and for 2003 to eliminate the time lag between the occurrence and recovery of net stranded costs inherent in the methodology approved in the December 2001 order. In November 2002, the MPSC Staff and other interveners submitted their 2002 net stranded cost filings. Detroit Edison expects to record 2002 net stranded costs as a regulatory asset with the offsetting entry reducing expense in the fourth quarter of 2002.

In another December 2001 order, the MPSC finalized the prices, terms and conditions contained in the Retail Access Service Tariff (RAST). Detroit Edison requested rehearing and clarification on certain aspects of the order. In an order issued in April 2002, the MPSC modified its December 2001 order approving Detroit Edison’s RAST and reduced the requirements imposed on Detroit Edison in the December 2001 order concerning meter installation, meter reading and computer system enhancements for customers that elect to participate in the electric Customer Choice program.

In several orders issued in June 2000, the MPSC determined that adjusting rates for changes in fuel and purchased power expenses through continuance of the PSCR clause would be inconsistent with the rate freeze required by PA 141. Detroit Edison was not permitted to collect the 1998 PSCR under-recovery of $9 million, plus accrued interest of $3 million. Also, Detroit Edison was not required to refund approximately $55 million of liabilities for over-recoveries of PSCR expenses for 1999 and 2000, and disallowances under the Fermi 2 performance standard mechanism. In January and March 2002, the Michigan Court of Appeals rejected appeals and motions for rehearing filed by parties opposing the MPSC’s actions in this proceeding. In March 2002, the Michigan Attorney General applied for leave to appeal at the Michigan Supreme Court. The court has not yet determined whether or not it will hear the case.

Other

In accordance with a November 1997 MPSC order, Detroit Edison reduced rates by $53 million annually to reflect the scheduled reduction in the revenue requirement for Fermi 2. The $53 million reduction was effective in January 1999. In addition, the November 1997 MPSC order authorized the deferral of $30 million of storm damage costs and amortization and recovery of the costs over a 24-month period commencing January 1998. After various legal appeals, the Michigan Court of Appeals remanded the matter to the MPSC. In December 2000, the MPSC issued an order reopening the case for hearing. The parties in the case have agreed to a stipulation of fact and waiver of hearing. In June 2002, the MPSC issued an order modifying in part, and reaffirming in part, previous orders that authorized Detroit Edison to amortize and collect in rates the storm damage costs incurred in 1997. The MPSC modified its 1997 order regarding the calculation of the storm damage costs, and in doing so ordered Detroit Edison to refund approximately $1.5 million after January 1, 2004. The 2004 refund will also include interest accrued from January 1, 2000 at Detroit Edison’s authorized rate of return. In July 2002, the Michigan Attorney General filed an appeal with the Michigan Court of Appeals regarding the June 2002 MPSC order.

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

NOTE 4 — CONTINGENCIES

Personal Property Taxes

Detroit Edison and other Michigan utilities have asserted that Michigan’s valuation tables result in the substantial overvaluation of utility personal property. Valuation tables established by the Michigan State Tax Commission (STC) are used to determine the taxable value of personal property based on the property’s age. In November 1999, the STC approved new valuation tables that more accurately recognize the value of a utility’s personal property. The new tables became effective in 2000 and are currently used to calculate property tax expense. However, several local taxing jurisdictions have taken legal action attempting to prevent the STC from implementing the new valuation tables and have continued to prepare assessments based on the superseded tables. The legal actions regarding the appropriateness of the new tables were before the Michigan Tax Tribunal (MTT) which, in April 2002, issued its decision essentially affirming the validity of the STC’s new tables. In June 2002, petitioners in the case filed an appeal of the MTT’s decision with the Michigan Court of Appeals.

Other

Detroit Edison purchases and sells electricity to numerous companies operating in the steel, automotive, energy and retail industries. During 2001 and 2002, a number of customers have filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code, including certain Enron Corporation affiliates and National Steel Company. Management regularly reviews contingent matters relating to purchase and sale contracts and records provisions for amounts considered probable of loss. Management believes its previously accrued amounts are adequate for losses that are probable of occurring. The final resolution of these matters are not expected to have a material effect on Detroit Edison’s financial statements in the period they are resolved.

NOTE 5 — LONG-TERM DEBT

On October 23, 2002, Detroit Edison issued $450 million of its senior notes ($225 million due 2012 at 5.20% and $225 million due 2032 at 6.35%). These notes are collateralized by Detroit Edison’s General and Refunding Mortgage Bonds.

Substantially all of the net utility property of Detroit Edison is subject to the lien of a Mortgage and Deed of Trust (Mortgage). Should Detroit Edison fail to timely pay its indebtedness under the Mortgage, such failure will create cross defaults in substantially all of Detroit Edison’s indebtedness.

NOTE 6 — SHORT TERM CREDIT ARRANGEMENTS AND BORROWINGS

On October 25, 2002, Detroit Edison entered into a $135 million, 364-day revolving credit facility and a $65 million, three-year revolving credit facility with a syndicate of banks. These credit facilities may be utilized for general corporate borrowings, but primarily are intended to provide liquidity support for Detroit Edison’s commercial paper program up to $200 million in amount. These agreements require Detroit Edison to maintain a debt to capitalization ratio of no more than 0.65 to 1 and an “earnings before interest, taxes, depreciation and amortization” (EBITDA) to interest ratio of no less than 2 to 1. Detroit Edison is currently in compliance with these financial covenants.

NOTE 7 — NEW ACCOUNTING PRONOUNCEMENTS

Goodwill and Other Intangible Assets - Effective January 1, 2002, Detroit Edison adopted SFAS No. 142, “Goodwill and Other Intangible Assets,” which addresses the financial accounting and reporting standards for the acquisition of intangible assets outside of a business combination and for goodwill and other intangible assets subsequent to their acquisition. As of the date of adoption, Detroit Edison had no goodwill.

In connection with the adoption of SFAS No. 142, Detroit Edison also reassessed the useful lives and the classification of identifiable intangible assets and determined that they continue to be appropriate. Detroit Edison’s intangible assets consist primarily of software and are subject to amortization. Intangible assets amortization expense was approximately $9 million and $27 million in the third quarter and nine-month period, respectively, compared with approximately $10 million and $29 million for the comparable 2001 periods. There were no material acquisitions of intangible assets during the 2002 nine-month period. The gross carrying amount and accumulated amortization of intangible assets at September 30, 2002 were $346 million and $261 million, respectively. Amortization expense of intangible assets is estimated to be $36 million annually for 2002 through 2006.

Asset Retirement Obligations - In June 2001, the FASB issued SFAS No. 143, “Accounting for Asset Retirement Obligations.” This statement requires that the fair value of an asset retirement obligation be recognized in the period in which it is incurred. The associated asset retirement costs would be capitalized as part of the carrying amount of the long-lived asset. It would apply to legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and (or) the normal operation of a long-lived asset. This statement is effective for financial statements issued for fiscal years beginning after June 15, 2002. Detroit Edison will adopt this statement in January 2003 and has not yet determined the impact of this statement on the consolidated financial statements.

Table of Contents

Notes to Consolidated Financial Statements (Unaudited)

Long-Lived Assets - On January 1, 2002, Detroit Edison adopted SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” SFAS No. 144 supersedes SFAS No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of,” but retains the fundamental provisions for recognizing and measuring impairment of long-lived assets to be held and used or disposed of by sale. The statement also supersedes the accounting and reporting provisions for the disposal of a segment of a business. SFAS No. 144 eliminates the conflict between accounting models for treating the disposition of long-lived assets that existed between SFAS No. 121 and the guidance for a segment of a business accounted for as a discontinued operation by adopting the methodology established in SFAS No. 121, and also resolves implementation issues related to SFAS No. 121. The adoption of the statement did not have an impact on the consolidated financial statements of Detroit Edison.

NOTE 8 — SEGMENT INFORMATION

During 2002, Detroit Edison’s parent company, DTE Energy, realigned its financial reporting structure into strategic business units that provide various regulated and non-regulated energy services. The realignment resulted in the following two reportable segments for Detroit Edison. Inter-segment revenues are not material.

INDEPENDENT ACCOUNTANTS’ REPORT

To the Board of Directors and Shareholder of
The Detroit Edison Company

We have reviewed the accompanying condensed consolidated statement of financial position of The Detroit Edison Company and subsidiaries as of September 30, 2002, and the related condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2002 and 2001, the condensed consolidated statement of cash flows for the nine-month periods ended September 30, 2002 and 2001, and the condensed consolidated statement of changes in shareholder’s equity for the nine-month period ended September 30, 2002. These financial statements are the responsibility of The Detroit Edison 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 The Detroit Edison Company and subsidiaries as of December 31, 2001, and the related consolidated statements of operations, cash flows and changes in shareholder’s equity for the year then ended (not presented herein); and in our report dated February 26, 2002 (September 17, 2002 as to Note 16), 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, 2001 is fairly stated, in all material respects, in relation to the consolidated statement of financial position from which it has been derived.

If the Company shall default in the payment of the interest due on any interest payment date on the principal represented by any bond of 2002 Series A, such defaulted interest shall forthwith cease to be payable to the registered holder of that bond on the relevant regular record date by virtue of his having been such holder, and such defaulted interest may be paid to the registered holder of that bond (or any bond or bonds of 2002 Series A issued upon transfer or exchange thereof) on the date of payment of such defaulted interest or, at the election of the Company, to the person in whose name that bond (or any bond or bonds of 2002 Series A issued upon transfer or exchange thereof) is registered on a subsequent record date established by notice given by mail by or on behalf of the Company to the holders of bonds of 2002 Series A not less than ten (10) days preceding such subsequent record date, which subsequent record date shall be at least five (5) days prior to the payment date of such defaulted interest.

Section 405 of the Note Indenture or in the supplemental indenture relating to the Notes, or, subject to compliance with applicable law, as may be involved in the course of the exercise of rights and remedies consequent upon an Event of Default under the Note Indenture. Any such transfer shall be made upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City and State of New York, together with a written instrument of transfer (if so required by the Company or by the Trustee) in form approved by the Company duly executed by the holder or by its duly authorized attorney. Bonds of 2002 Series A shall in the same manner be exchangeable for a like aggregate principal amount of bonds of 2002 Series A upon the terms and conditions specified herein and in Section 7 of Article II of the Indenture.

                           prior to maturity by redemption or otherwise, or upon
                           provision for the payment thereof having been made in
                           accordance with Article V of the Note Indenture,

                           extent of such payment of principal, premium or
                           interest, be deemed fully paid and the obligation of
                           the Company thereunder to make such payment shall
                           forthwith cease and be discharged, and, in the case
                           of the payment of principal and premium, if any, such
                           bonds shall be surrendered for cancellation or
                           presented for appropriate notation to the Trustee.

                           to the Release Date, it will not take any action that
                           would cause the outstanding principal amount of the
                           bonds of 2002 Series A to be less than the then
                           outstanding principal amount of the Notes.

This bond and all other bonds of said series are issued and to be issued under, and are all equally and ratably secured (except insofar as any sinking, amortization, improvement or analogous fund, established in accordance with the provisions of the Indenture hereinafter mentioned, may afford additional security for the bonds of any particular series and except as provided in Section 3 of Article VI of said Indenture) by an Indenture, dated as of October 1, 1924, duly executed by the Company to Bank One, National Association, as successor in interest to Bankers Trust Company, a corporation organized under the laws of the Untied States, as Trustee, to which Indenture and all indentures supplemental thereto (including the Supplemental Indenture dated as of October 15, 2002) reference is hereby made for a description of the properties and franchises mortgaged and conveyed, the nature and extent of the security, the terms and conditions upon which the bonds are issued and under which additional bonds may be issued, and the rights of the holders of the bonds and of the Trustee in respect of such security (which Indenture and all indentures supplemental thereto, including the Supplemental Indenture dated as of October 15, 2002, are hereinafter collectively called the "Indenture"). As provided in the Indenture, said bonds may be for various principal sums and are issuable in series, which may mature at different times, may bear interest at different rates and may otherwise vary as in said Indenture provided. With the consent of the Company and to the extent permitted by and as provided in the Indenture, the rights and obligations of the Company and of the holders of the bonds and the terms and provisions of the Indenture, or of any indenture supplemental thereto, may be modified or altered in certain respects by affirmative vote of at least eighty-five percent (85%) in amount of the bonds then outstanding, and, if the rights of one or more, but less than all, series of bonds then outstanding are to be affected by the action proposed to be taken, then also be affirmative vote of at least eighty-five percent (85%) in amount of the series of bonds so to be affected (excluding in every instance bonds disqualified from voting by reason of the Company's interest therein as specified in the Indenture); provided, however, that, without the consent of the holder hereof, no such modification or alteration shall, among other things, affect the terms of payment of the principal of or the interest on this bond, which in those respects is unconditional.

20

This bond is redeemable upon the terms and conditions set forth in the Indenture, including provision for redemption upon demand of the Note Indenture Trustee following the occurrence of an Event of Default under the Note Indenture and the acceleration of the principal of the Notes.

Under the Indenture, funds may be deposited with the Trustee (which shall have become available for payment), in advance of the redemption date of any of the bonds of 2002 Series A (or portions thereof), in trust for the redemption of such bonds (or portions thereof) and the interest due or to become due thereon, and thereupon all obligations of the Company in respect of such bonds (or portions thereof) so to be redeemed and such interest shall cease and be discharged, and the holders thereof shall thereafter be restricted exclusively to such funds for any and all claims of whatsoever nature on their part under the Indenture or with respect to such bonds (or portions thereof) and interest.

In case an event of default, as defined in the Indenture, shall occur, the principal of all the bonds issued thereunder may become or be declared due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

Upon payment of the principal of, or premium, if any, or interest on, the Notes, whether at maturity or prior to maturity by redemption or Otherwise or upon provision for the payment thereof having been made in accordance with Article V of the Note Indenture, bonds of 2002 Series A in a principal amount equal to the principal amount of such Notes, and having both a corresponding maturity date and interest rate shall, to the extent of such payment of principal, premium or interest, be deemed fully paid and the obligation of the Company thereunder to make such payment shall forthwith cease and be discharged, and, in the case of the payment of principal and premium, if any, such bonds of said series shall be surrendered for cancellation or presented for appropriate notation to the Trustee.

21

This bond is not assignable or transferable except as set forth under Section 405 of the Note Indenture or in the supplemental indenture relating to the Notes, or, subject to compliance with applicable law, as may be involved in the course of the exercise of rights and remedies consequent upon an Event of Default under the Note Indenture. Any such transfer shall be made by the registered holder hereof, in person or by his attorney duly authorized in writing, on the books of the Company kept at its office or agency in the Borough of Manhattan, The City and State of New York, upon surrender and cancellation of this bond, and thereupon, a new registered bond of the same series of authorized denominations for a like aggregate principal amount will be issued to the transferee in exchange therefor, and this bond with others in like form may in like manner be exchanged for one or more new bonds of the same series of other authorized denominations, but of the same aggregate principal amount, all as provided and upon the terms and conditions set forth in the Indenture, and upon payment, in any event, of the charges prescribed in the Indenture.

From and after the Release Date (as defined in the Note Indenture), the bonds of 2002 Series A shall be deemed fully paid, satisfied and discharged and the obligation of the Company thereunder shall be terminated. On the Release Date, the bonds of 2002 Series A shall be surrendered to and cancelled by the Trustee. The Company covenants and agrees that, prior to the Release Date, it will not take any action that would cause the outstanding principal amount of the bond of 2002 Series A to be less than the then outstanding principal amount of the Notes.

No recourse shall be had for the payment of the principal of or the interest on this bond, or for any claim based hereon or otherwise in respect hereof or of the Indenture, or of any indenture supplemental thereto, against any incorporator, or against any past, present or future stockholder, director or officer, as such, of the Company, or of any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation, whether for amounts unpaid on stock subscriptions or by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise howsoever; all such liability being, by the acceptance hereof and as art of the consideration for the issue hereof, expressly waived and released by every holder or owner hereof, as more fully provided in the Indenture.

[FORM OF REVERSE OF BOND]

This bond is one of an authorized issue of bonds of the Company, unlimited as to amount except as provided in the Indenture hereinafter mentioned or any indentures supplemental thereto, and is one of a series of General and Refunding Mortgage Bonds known as 2002 Series B, limited to an aggregate principal amount of $225,000,000, except as otherwise provided in the Indenture hereinafter mentioned. This bond and all other bonds of said series are issued and to be issued under, and are all equally and ratably secured (except insofar as any sinking, amortization, improvement or analogous fund, established in accordance with the provisions of the Indenture hereinafter mentioned, may afford additional security for the bonds of any particular series and except as provided in Section 3 of Article VI of said Indenture) by an Indenture, dated as of October 1, 1924, duly executed by the Company to Bank One, National Association, as successor in interest to Bankers Trust Company, a corporation organized under the laws of the United States, as Trustee, to which Indenture and all indentures supplemental thereto (including the Supplemental Indenture dated as of October 15, 2002) reference is hereby made for a description of the properties and franchises mortgaged and conveyed, the nature and extent of the security, the terms and conditions upon which the bonds are issued and under which additional bonds may be issued, and the rights of the holders of the bonds and of the Trustee in respect of such security (which Indenture and all indentures supplemental thereto, including the Supplemental Indenture dated as of , are hereinafter collectively called the "Indenture"). As provided in the Indenture, said bonds may be for various principal sums and are issuable in series, which may mature at different times, may bear interest at different rates and may otherwise vary as in said Indenture provided. With the consent of the Company and to the extent permitted by and as provided in the Indenture, the rights and obligations of the Company and of the holders of the bonds and the terms and provisions of the Indenture, or of any indenture supplemental thereto, may be modified or altered in certain respects by affirmative vote of at least eighty-five percent (85%) in amount of the bonds then outstanding, and, if the rights of one or more, but less than all, series of bonds then outstanding are to be affected by the action proposed to be taken, then also be affirmative vote of at least eighty-five percent (85%) in amount of the series of bonds so to be affected (excluding in every instance bonds disqualified from voting by reason of the Company's interest therein as specified in the Indenture); provided, however, that, without the consent of the holder hereof, no such modification or alteration shall, among other things, affect the terms of payment of the principal

31

of or the interest on this bond, which in those respects is unconditional.

This bond is redeemable upon the terms and conditions set forth in the Indenture, including provision for redemption upon demand of the Note Indenture Trustee following the occurrence of an Event of Default under the Note Indenture and the acceleration of the principal of the Notes.

Under the Indenture, funds may be deposited with the Trustee (which shall have become available for payment), in advance of the redemption date of any of the bonds of 2002 Series B (or portions thereof), in trust for the redemption of such bonds (or portions thereof) and the interest due or to become due thereon, and thereupon all obligations of the Company in respect of such bonds (or portions thereof) so to be redeemed and such interest shall cease and be discharged, and the holders thereof shall thereafter be restricted exclusively to such funds for any and all claims of whatsoever nature on their part under the Indenture or with respect to such bonds (or portions thereof) and interest.

In case an event of default, as defined in the Indenture, shall occur, the principal of all the bonds issued thereunder may become or be declared due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

Upon payment of the principal of, or Premium, if any, or interest on, the Notes, whether at maturity or prior to maturity by redemption or otherwise or upon provision for the Payment thereof having been made in accordance with Article V of the Note Indenture, bonds of 2002 Series B in a principal amount equal to the Principal amount of such Notes, and having both a corresponding maturity date and interest rate shall, to the extent of such payment of Principal, premium or interest, be deemed fully paid and the obligation of the Company thereunder to make such payment shall forthwith cease and be discharged, and, in the case of the payment of Principal and premium, if any, such bonds of said series shall be surrendered for cancellation or presented for appropriate notation to the Trustee.

32

                                 This bond is not assignable or transferable
                           except as set forth under Section 405 of the Note
                           Indenture or in the supplemental indenture relating
                           to the Notes, or, subject to compliance with
                           applicable law, as may be Involved in the course of
                           the exercise of rights and remedies consequent upon
                           an Event of Default under the Note Indenture. Any
                           such transfer shall be made by the registered holder
                           hereof, in person or by his attorney duly authorized
                           in writing, on the books of the Company kept at its

                           cancellation of this bond, and thereupon, a new
                           registered bond of the same series of authorized
                           denominations for a like aggregate principal amount
                           will be issued to the transferee in exchange
                           therefor, and this bond with others in like form may
                           in like manner be exchanged for one or more new bonds
                           of the same series of other authorized denominations,
                           but of the same aggregate principal amount, all as
                           provided and upon the terms and conditions set forth
                           in the Indenture, and upon payment, in any event, of
                           the charges prescribed in the Indenture.

                                 From and after the Release Date (as defined in
                           the Note Indenture), the bonds of 2002 Series B shall
                           be deemed fully paid, satisfied and discharged and
                           the obligation of the Company thereunder shall be
                           terminated. On the Release Date, the bonds of 2002

                           to the Release Date, it will not take any action that
                           would cause the outstanding principal amount of the
                           bond of 2002 Series B to be less than the then
                           outstanding principal amount of the Notes.

                                 No recourse shall be had for the payment of the
                           principal of or the interest on this bond, or for any

For purposes of the Original Indenture, each series of the Notes shall separately constitute a single series of Securities. The Stated Maturity on which the principal of the 5.20% Notes shall be due and payable will be October 15, 2012. The Stated Maturity on which the principal of the 6.35% Notes shall be due and payable will be October 15, 2032.

SECTION 2.02. Certain Variations from the Original Indenture. (a) The Notes shall have the benefit of the provisions of Article Four of the Original Indenture and shall have the benefit of, or be subject to, the other related provisions of the Original Indenture relating to the grant of security, including (for avoidance of doubt and not for purposes of limitation) the Granting Clause, the definitions of "Deliverable Mortgage Bonds," "Deliverable Securities," "Designated Mortgage Bonds," "Grant," "Mortgage," "Mortgage Bonds," "Mortgage Trustee," "Previously Delivered

4

Mortgage Bonds," and "Trust Estate," Section 301 (20), Sections 301 (a) (v),
(ix), (x) and (xi), Sections 301 (b) (ii) and (iii), Section 301 (d), and Sections 601(4) and (8), subject, in each case, to the release provisions provided for in Section 4.02 herein. In addition, on and after the Release Date, unless Substitute Mortgage Bonds are issued to secure the Notes, the Notes shall have the benefit of the additional covenants set forth in Article Three hereof.

(b) Section 503 of the Original Indenture shall apply to the Notes. The following shall be an additional condition to defeasance of the Notes under
Section 503: the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from the Internal Revenue Service a letter ruling, or there has been published by the Internal Revenue Service a Revenue Ruling, or (ii) since the date of execution of this Supplemental Indenture, there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Notes appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred, and, also, to the effect that, after the 123rd day after the date of deposit, all money and other property as provided pursuant to Section 503 of the Original Indenture (including the proceeds thereof) deposited or caused to be deposited with the Trustee (or other qualifying trustee) pursuant to Section 503 of the Original Indenture to be held in trust will not be subject to any case or proceeding (whether voluntary or involuntary) in respect of the Company under any Federal or State bankruptcy, insolvency, reorganization or other similar law, or any decree or order for relief in respect of the Company issued in connection therewith.

SECTION 2.03. Amount and Denominations; DTC.

(a) The aggregate principal amount of Notes that may be issued under this Supplemental Indenture is limited initially to $225,000,000 (in the case of the 5.20% Notes), and $225,000,000 (in the case of the 6.35% Notes) (except, in each case, as provided in Section 301(2) of the Original Indenture); provided that the Company may, without the consent of the Holders of the Outstanding Notes of any series, "reopen" each series of Notes so as to increase the aggregate principal amount of such Notes Outstanding in compliance with the procedures set forth in the Original Indenture, including Section 301 and Section 303 thereof, so long as any such additional Notes have the same tenor and terms (including, without limitation, rights to security and to receive accrued and unpaid interest) as the Notes of such series then Outstanding. No additional Notes of a series may be issued if an Event of Default has occurred with respect to the applicable series. The Notes shall be issuable only in fully registered form and, as permitted by Section 301 and Section 302 of the Original Indenture, in denominations of $1,000 and integral multiples thereof. The Notes will initially be issued in global form (the "Global Notes") under a book-entry system, registered in the name of The Depository Trust Company, as depository ("DTC"), or its nominee, which is hereby designated as "Depository" under the Indenture.

(b) Further to Section 305 of the Original Indenture, any Global Note shall be exchangeable for Notes registered in the name of, and a transfer of a Global Note of any series may be registered to, any Person other than the Depository for such Note or its nominee only if (i) such Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Note or if at any time such Depository ceases to be a clearing agency registered under the Exchange Act, and, in either such case, the Company does not appoint a successor Depository within 90 days thereafter, (ii) the Company executes and delivers to the Trustee a Company Order that such Global Note shall be so exchangeable and the transfer thereof so registrable or (iii) there shall have

5

occurred and be continuing an Event of Default or an event which, with the giving of notice or lapse of time, or both, would constitute an Event of Default with respect to the Notes of such series. Upon the occurrence in respect of any Global Note of any series of any or more of the conditions specified in clause
(i), (ii) or (iii) of the preceding sentence, such Global Note may be exchanged for Notes registered in the name of, and the transfer of such Global Note may be registered to, such Persons (including Persons other than the Depository with respect to such series and its nominees) as such Depository, in the case of an exchange, and the Company, in the case of a transfer, shall direct.

SECTION 2.04. Certain Common Terms of the Notes.

(a) The 5.20% Notes shall bear interest at the rate of 5.20% per annum (), and the 6.35% Notes shall bear interest at the rate of 6.35% per annum on the respective principal amount thereof from October 23, 2002, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, until the principal of such series of Notes becomes due and payable, and on any overdue principal and premium and (to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the same rate per annum during such overdue period. Interest on the Notes will be payable semiannually in arrears on April 15 and October 15 of each year (each such date, an "Interest Payment Date"), commencing April 15, 2003. The amount of interest payable for any period shall be computed on the basis of twelve 30-day months and a 360-day year.

(b) In the event that any Interest Payment Date, redemption date or other date of Maturity of the Notes is not a Business Day, then payment of the amount payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), in each case with the same force and effect as if made on such date. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date with respect to any Note will, as provided in the Original Indenture, be paid to the person in whose name the Note (or one or more Predecessor Securities, as defined in said Indenture) is registered at the close of business on the relevant record date for such interest installment, which shall be the fifteenth calendar day (whether or not a Business Day) prior to the relevant Interest Payment Date (the "Regular Record Date"). Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such Regular Record Date, and may either be paid to the person in whose name the Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date to be fixed by the Trustee for the payment of such defaulted interest, notice whereof shall be given to the registered Holders of the applicable series of Notes not less than ten days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Original Indenture. The principal of, and premium, if any, and the interest on the Notes shall be payable at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York, in any coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered Holder at the close of business on the Regular Record Date at such address as shall appear in the Security Register. Notwithstanding the foregoing, so long as the Notes are Global Notes and are held in book-entry form through the facilities of the Depository, payments on the Notes will be made to the Depository or its nominee in accordance with arrangements then in effect between the Trustee and the Depository.

6

(c) The Notes are not subject to repayment at the option of the Holders thereof and are not subject to any sinking fund. As provided in the forms of Note attached hereto as Exhibit A and Exhibit B, respectively, the Notes are subject to optional redemption, as a whole or in part, by the Company prior to Stated Maturity of the principal thereof on the terms set forth therein. Except as modified in the forms of the Notes, redemptions shall be effected in accordance with Article Twelve of the Original Indenture.

(d) The Notes shall have such other terms and provisions as are set forth in the form of Note attached hereto as Exhibit A and Exhibit B, as applicable (each of which are incorporated by reference in and made a part of this Supplemental Indenture as if set forth in full at this place).

SECTION 2.05. Form of Notes. Attached hereto as Exhibit A is the form of the definitive 5.20% Notes. Attached hereto as Exhibit B is the form of the definitive 6.35% Notes. If the Company elects to have the Notes secured by Substitute Mortgage Bonds on and after the Release Date, the terms of the Notes shall be amended to make appropriate reference to the Substitute Mortgage and the Substitute Mortgage Bonds; provided, that the consent of Holders shall not be required in connection with such amendment.

ARTICLE THREE

ADDITIONAL COVENANTS

SECTION 3.01. Limitations on Liens. (a) From and after the Release Date, unless Substitute Mortgage Bonds are issued to secure the Notes, so long as any Notes are outstanding, the Company may not issue, assume, guarantee (including any contingent obligation to purchase) or permit to exist any Debt that is secured by any mortgage, security interest, pledge or lien ("Lien") of or upon any Operating Property owned by the Company, whether owned at the Release Date or subsequently acquired, without effectively securing the Notes (together with, if the Company shall so determine, any other indebtedness of the Company ranking equally with the Notes) equally and ratably with the Debt (but only so long as the Debt is so secured).

The foregoing restriction will not apply to:

(i) Liens on any Operating Property existing at the time of its acquisition and not created in contemplation of the acquisition;

(ii) Liens on Operating Property of a corporation existing at the time the corporation is merged into or consolidated with the Company, or at the time the corporation disposes of substantially all of its properties (or those of a division) to the Company, provided that the Lien is not extended to property owned by the Company immediately prior to the merger, consolidation or other disposition and is not created in contemplation of the merger, consolidation or other disposition;

(iii) Liens on Operating Property to secure the cost of acquisition, construction, development or substantial repair, alteration or improvement of such property or to secure indebtedness incurred to provide funds for any of these purposes or for reimbursement of funds previously expended for any of these purposes, provided the Liens are created or assumed contemporaneously with, or within 18 months after, the acquisition or the completion of substantial repair or alteration, construction, development or substantial improvement or

7

within 6 months thereafter pursuant to a commitment for financing arranged with a lender or investor within such 18-month period;

(iv) Liens in favor of the United States or any state or any department, agency or instrumentality or political subdivision of the United States or any state, or for the benefit of holders of securities issued by any of these entities, to secure any Debt incurred for the purpose of financing all or any part of the purchase price or the cost of substantially repairing or altering, constructing, developing or substantially improving the Operating Property of the Company; or

(v) Any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Lien referred to in the exceptions listed above, provided, however, that the principal amount of Debt secured thereby and not otherwise authorized by those exceptions listed above shall not exceed the principal amount of Debt, plus any premium or fee payable in connection with any such extension, renewal or replacement, so secured at the time of such extension, renewal or replacement.

(b) In addition, notwithstanding the foregoing restrictions, from and after the Release Date, the Company may issue, assume or guarantee Debt secured by a Lien which would otherwise be subject to the foregoing restrictions up to an aggregate amount which, together with all other of the Company's secured Debt (not including secured Debt permitted under any of the foregoing exceptions) and the Value of Sale and Lease-Back Transactions existing at such time (other than Sale and Lease-Back Transactions the proceeds of which have been applied to the retirement of certain indebtedness, Sale and Lease-Back Transactions in which the property involved would have been permitted to be subjected to a Lien under any of the foregoing exceptions, and Sale and Lease-Back Transactions that are permitted by the first sentence of Section 3.02 below), does not exceed the greater of 10% of the Company's Net Tangible Assets or 10% of the Company's Capitalization. The foregoing restrictions do not limit the Company's ability to place Liens on (i) the capital stock of any of the Company's subsidiaries or
(ii) the assets of any of the Company's subsidiaries.

SECTION 3.02. Limitations on Sale and Lease-Back Transactions. So long as the Notes are outstanding from and after the Release Date, unless Substitute Mortgage Bonds are issued to secure the Notes, the Company may not enter into or permit to exist any Sale and Lease-Back Transaction with respect to any Operating Property (except for leases for a term, including any renewal or potential renewal, of not more than 48 months), if the purchaser's commitment is obtained more than 18 months after the later of the completion of the acquisition, construction or development of the Operating Property or the placing in operation of the Operating Property or of the Operating Property as constructed or developed or substantially repaired, altered or improved. This restriction will not apply if (a) the Company would be entitled pursuant to
Section 3.01(a) above to issue, assume, guarantee or permit to exist Debt secured by a Lien on the Operating Property without equally and ratably securing the Notes, (b) after giving effect to the Sale and Lease-Back Transaction, pursuant to Section 3.01(b) above, the Company could incur, at least $1.00 of additional Debt secured by Liens (other than Liens permitted by clause (a)), or
(c) the Company applies within 180 days an amount equal to, in the case of a sale or transfer for cash, the net proceeds (not less than the fair value of the Operating Property so leased), and, otherwise, an amount equal to the fair value (as determined by the Board of Directors of the Company) of the Operating Property so leased to the retirement of Notes or other Debt of the Company ranking equally with the Notes; provided, however, that any such retirement of Notes shall be in accordance with the terms and provisions of the Indenture and the Notes; provided, further, that

8

the amount to be applied to such retirement of Notes or other Debt shall be reduced by an amount equal to the sum of (a) an amount equal to the redemption price with respect to Notes delivered within such one hundred eighty (180)-day period to the Trustee for retirement and cancellation and (b) the principal amount, plus any premium or fee paid in connection with any redemption in accordance with the terms of other Debt voluntarily retired by the Company within such one hundred eighty (180)-day period, excluding in each case retirements pursuant to mandatory sinking fund or prepayment provisions and payments at maturity.

SECTION 3.03. Waiver. Section 1109 of the Original Indenture shall apply to the covenants set forth in Sections 3.01 and 3.02 above at any time such covenants are in effect.

ARTICLE FOUR

SECURITY AND RELEASE PROVISIONS

SECTION 4.01. Security. Subject to Section 4.02 below, as provided in and pursuant to Article Four of the Original Indenture, each series of the Notes will be secured as to payments of principal, interest and premium, if any, by a series of Mortgage Bonds (the "General and Refunding Mortgage Bonds, 2002 Series A", in the case of the 5.20% Notes, and the "General and Refunding Mortgage Bonds, 2002 Series B", in the case of the 6.35% Notes, or, singly or collectively, the "Bonds," the "Bonds of the related series" or the "related series of Bonds") of the Company to be issued concurrently with the issuance of the Notes under and secured by a Mortgage and Deed of Trust, dated as of October 1, 1924, between the Company and Bank One, National Association, as successor trustee (the "Mortgage Trustee"), as amended and supplemented by various supplemental indentures, including the supplemental indenture, dated as of October 15, 2002 creating the Bonds (collectively, the "Mortgage"), pledged by the Company for the benefit of the Holders of the respective series of Notes to the Trustee under this Supplemental Indenture. The Bonds shall be issued in an aggregate principal amount equal to the aggregate principal amount of the Notes.

SECTION 4.02. Release. Until the Release Date and subject to Article Four of the Original Indenture, the Bonds of the related series issued and delivered to the Trustee shall serve as security for any and all obligations of the Company under all Notes of the applicable series from time to time Outstanding, including, but not limited to (1) the full and prompt payment of the principal and premium, if any, on such Notes when and as the same shall become due and payable in accordance with the terms and provisions of the Indenture or such Notes, either at the Stated Maturity thereof, upon acceleration of the maturity thereof, upon redemption, or otherwise, and (2) the full and prompt payment of any interest on such Notes when and as the same shall become due and payable in accordance with the terms and provisions of this Indenture or the Notes including, if and to the extent provided for in such Notes, interest on overdue installments of principal and (to the extent permitted by law) interest on overdue installments of interest.

Each supplemental indenture to the Mortgage pursuant to which any Bonds are issued shall contain a provision to the effect that any payment by the Company hereunder of principal of or premium or interest on Notes which shall have been authenticated and delivered in connection with the issuance and delivery to the Trustee of such Bonds (other than by the application of the proceeds of a payment in respect of such Bonds) shall to the extent thereof, be deemed to satisfy and discharge the obligation of the Company, if any, to make a payment of principal, premium or interest, as the case may be, in respect of such Bonds which is then due.

Notwithstanding anything in the Original Indenture to the contrary, from and after the Release Date, the obligation of the Company to make payment with respect to the principal of and premium, if any, and interest on the Bonds shall be deemed satisfied and discharged as provided in the supplemental indenture or indentures to the Mortgage creating such Bonds and the Bonds shall cease to secure in any manner Notes theretofore or subsequently issued; the Trustee shall thereupon surrender the Bonds to the Mortgage Trustee for cancellation and execute and deliver such proper instruments of release as may be required. From and after the Release Date, all Notes, whether theretofore or subsequently issued, shall, at the Company's option, either (i) become unsecured or (ii) be secured by Substitute Mortgage Bonds pursuant to Section 4.03 below, and any conditions to the issuance of Notes that refer or relate to Bonds or the Mortgage shall be inapplicable (except as such conditions shall be deemed to refer to Substitute Mortgage Bonds or a Substitute Mortgage pursuant to Section 4.03 below). From and after the Release Date, the Company shall not issue any additional Mortgage Bonds, including Pledged Bonds, under the Mortgage. Notice of the occurrence of the Release Date shall be given by the Trustee to the Holders of the Notes in the manner provided for in the Original Indenture not later than 30 days after the Company notifies the Trustee of the occurrence of the Release Date.

In connection with the establishment of the occurrence of the Release Date, the Trustee shall be entitled to receive, may presume the correctness of, and shall be fully protected in relying upon, an Officers' Certificate designating the Release Date and stating that the conditions to the occurrence of the Release Date have been satisfied.

When the obligation of the Company to make payments with respect to the principal of, and premium, if any, and interest on all or any part of the Bonds shall be satisfied or deemed satisfied pursuant to the Original Indenture or pursuant to this Supplemental Indenture, the Trustee shall, upon written request of the Company, deliver to the Company without charge therefor all of the Bonds so satisfied or deemed satisfied, together with such appropriate instruments of transfer or release as may be reasonably requested by the Company. All Bonds delivered to the Company in accordance with this Section shall be delivered by the Company to the Mortgage Trustee for cancellation.

SECTION 4.03. Substitute Mortgage Bonds.

(a) The Company shall notify the Trustee not less than 90 days prior to the Release Date (or such shorter period as the Company and the Trustee may agree) that the Company has determined to deliver to the Trustee on the Release Date Substitute Mortgage Bonds in an aggregate principal amount equal to the aggregate principal amount of Notes and any other Securities subject to the release provisions Outstanding on the Release Date, in trust for the benefit of the Holders from time to time of the Notes and any other Securities subject to the release provisions issued under the Original Indenture, as supplemented, as security for any and all obligations of the Company under the Notes and any other Securities subject to the release provisions, including but not limited to, (1) the full and prompt payment of the principal of and premium, if any, on the Notes and any other Securities subject to the release provisions when and as the same shall become due and payable in accordance with the terms and provisions of the Original Indenture, as supplemented, or the Notes or such other Securities subject to the release provisions, either at the stated maturity thereof, upon acceleration of the maturity thereof or upon redemption, and (2) the full and prompt payment of any interest on the Notes and any other Securities subject to the release provisions when and as the same shall become due and payable in accordance with the terms and provisions of the Original Indenture, as supplemented, or the Notes or such other Securities subject to the release provisions.

10

(b) The Substitute Mortgage Bonds to be delivered pursuant to the notice described in Section 4.03(a) shall be delivered in separate series and issues corresponding to the series and issues of Notes and other Securities subject to the release provisions Outstanding on the Release Date, each series or issue of Substitute Mortgage Bonds having the same stated rate or rates of interest (or interest calculated in the same manner), Interest Payment Dates, stated maturity date and redemption provisions, and in the same aggregate principal amount, as the related series or issue of Notes or other Securities subject to the release provisions outstanding on the Release Date. The Company shall enter into a Substitute Mortgage for the issuance of Substitute Mortgage Bonds, and designate it as such in the notice.

(c) The notice described in Section 4.03(a) shall also state that on the Release Date the Company shall deliver to the Trustee a supplemental indenture to the Original Indenture that will provide, among other things, that upon the issuance of Notes and other Securities subject to the release provisions on or after the Release Date, the Company shall deliver to the Trustee in trust for the benefit of the Holders as described in Section 4.03(a) hereof, and the Trustee shall accept therefor, related series of Substitute Mortgage Bonds registered in the name of the Trustee and conforming to the requirements therein specified.

(d) The determination whether to deliver Substitute Mortgage Bonds shall be made in the Company's sole discretion and without any obligation to do so.

(e) In the event that the Company does not deliver the notice described in
Section 4.03(a), the Notes and other Securities subject to the release provisions Outstanding on the Release Date shall, as of the Release Date, no longer be entitled to the benefit of the pledge of the Pledged Bonds and shall thereafter be general unsecured obligations of the Company.

(f) Article Four and related provisions of the Original Indenture shall apply to Substitute Mortgage Bonds pledged to the Trustee hereunder and the provisions thereof shall be deemed to refer to the Substitute Mortgage and the Substitute Mortgage Bonds. If the Company elects to have the Notes secured by Substitute Mortgage Bonds on and after the Release Date, Article Four and related provisions may be amended to make appropriate reference to the Substitute Mortgage and the Substitute Mortgage Bonds; provided, that the consent of Holders shall not be required in connection with such amendment.

SECTION 4.04. Events of Default.

(a) On and after the Release Date, Section 601(8) of the Original Indenture shall no longer apply to the Notes.

(b) On and after the Release Date, if the Notes become secured by Substitute Mortgage Bonds pursuant to Section 4.03 above, the occurrence of a "default" (as defined in the Substitute Mortgage) shall constitute an Event of Default under
Section 601 of the Original Indenture with respect to the Notes and the references in Section 601(4) of the Original Indenture and related provisions to "Mortgage Bonds" shall be deemed to refer to "Substitute Mortgage Bonds."

This Note shall not be entitled to any benefit under the Indenture hereinafter referred to, be valid or become obligatory for any purpose until the Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee.

Unless the Certificate of Authentication hereon has been executed by the Trustee or a duly appointed Authentication Agent referred to herein, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Note is one of a duly authorized series of Securities of the Company (herein sometimes referred to as the "Notes"), specified in the Indenture, all issued or to be issued in one or more series under and pursuant to a Collateral Trust Indenture dated as of June 30, 1993 (the "Original Indenture") duly executed and delivered between the Company and Bank One Trust Company, National Association, as Trustee (herein referred to as the "Trustee"), as supplemented through and including a Tenth Supplemental Indenture dated as of October 23, 2002 (together with the Original Indenture, the "Indenture") between the Company and the Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the registered Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.

This Note is not subject to repayment at the option of the Holder hereof. Except as provided below, this Note is not redeemable by the Company prior to maturity and is not subject to any sinking fund.

This Note will be redeemable at the option of the Company, in whole at any time or in part from time to time, (any such date of optional redemption, an "Optional Redemption Date," which shall be a "Redemption Date" for purposes of the Indenture), at an optional redemption price (which shall be a "Redemption Price" for purposes of the Indenture) equal to the greater of (i) 100% of the principal amount of this Note to be redeemed and (ii) the sum of the present values of the principal amount of this Note to be redeemed and the remaining scheduled payments of interest on the principal amount of this Note to be redeemed (exclusive of interest accrued to the related Optional Redemption Date) until Stated Maturity, in each case discounted from their respective scheduled payment dates to such Optional Redemption Date on a semiannual basis (assuming a 360-day year consisting of 30-day months) at the Adjusted Treasury Rate (as defined below) plus 30 basis points, as determined by the Reference Treasury Dealer, plus accrued interest thereon to the date of redemption.

Notwithstanding the foregoing, installments of interest on this Note that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant Record Date.

"Adjusted Treasury Rate" means, with respect to any Optional Redemption Date, the rate per annum equal to the semiannual yield to maturity of the Comparable Treasury Issue, calculated on the third Business Day preceding such Optional Redemption Date, using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Optional Redemption Date.

17

"Comparable Treasury Issue" means the United States Treasury security determined by the Reference Treasury Dealer selected by the Company as having a maturity comparable to the remaining term of this Note that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity with the remaining term of this Note.

"Comparable Treasury Price" means, with respect to any Optional Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Optional Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than two such Reference Treasury Dealer Quotations, the average of all such quotations, or
(iii) if only one Reference Treasury Dealer Quotation is received, such quotation.

"Reference Treasury Dealer" means each of: (i) Barclays Capital Inc. and Salomon Smith Barney Inc. (or their respective affiliates which are Primary Treasury Dealers), and their respective successors; provided, however, that if any of the foregoing cease to be a primary U.S. Government securities dealer in The City of New York (a "Primary Treasury Dealer"), the Company shall substitute therefor another Primary Treasury Dealer; and (ii) any other Primary Treasury Dealer(s) selected by the Trustee after consultation with the Company.

"Reference Treasury Dealer Quotation" means, with respect to each Reference Treasury Dealer and any Optional Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Optional Redemption Date.

Notice of any optional redemption will be mailed at least 30 days but not more than 60 days before the Optional Redemption Date to the Holder hereof at its registered address.

Unless the Company defaults in payment of the applicable Redemption Price, on and after the applicable Redemption Date interest will cease to accrue on the principal amount of this Note called for redemption.

If money sufficient to pay the applicable Redemption Price with respect to the principal amount of and accrued interest on the principal amount of this Note to be redeemed on the applicable Redemption Date is deposited with the Trustee or Paying Agent on or before the related Redemption Date and certain other conditions are satisfied, then on or after such date, interest will cease to accrue on the principal amount of this Note called for redemption.

If the Notes are only partially redeemed by the Company, the Trustee shall select which Notes are to be redeemed in a manner it deems fair and appropriate in accordance with the terms of the Indenture.

In the event of redemption of this Note in part only, a new Note or Notes of this series for the unredeemed portion hereof will be issued in the name of the registered Holder hereof upon the cancellation hereof.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Notes may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

18

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Note upon compliance by the Company with certain conditions set forth therein.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the registered Holders of not less than a majority in aggregate principal amount of the outstanding Securities of each series affected at the time, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the registered Holders of the Securities; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Securities of any series, or reduce the principal amount thereof, or reduce the rate of or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, without the consent of the registered Holder of each Security so affected or (ii) reduce the aforesaid percentage of Securities, the registered Holders of which are required to consent to any such supplemental indenture, without the consent of the registered Holders of each Security then outstanding and affected thereby. The Indenture also contains provisions permitting (i) the registered Holders of at least 66 2/3% in aggregate principal amount of the Securities of all series at the time outstanding affected thereby, on behalf of the registered Holders of the Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and (ii) the registered Holders of a majority in aggregate principal amount of the Securities of all series at the time outstanding affected thereby, on behalf of the registered Holders of the Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the registered Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such registered Holder and upon all future registered Holders and owners of this Note and of any Note issued in exchange hereof or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the time and place and at the rate and in the coin or currency herein prescribed.

Prior to the Release Date, the Notes of this series shall be secured by a series of Mortgage Bonds (the "Related Series of Bonds"), delivered by the Company to the Trustee for the benefit of the Holders of the Notes. Reference is made to the Mortgage and the Indenture for a description of the rights of the Trustee as Holder of the Related Series of Bonds, the property mortgaged and pledged under the Mortgage and the rights of the Company and of the Mortgage Trustee in respect thereof, the duties and immunities of the Mortgage Trustee and the terms and conditions upon which the Related Series of Bonds are secured and the circumstances under which additional Mortgage Bonds may be issued.

FROM AND AFTER SUCH TIME AS ALL BONDS, OTHER THAN (1) PLEDGED BONDS, INCLUDING THE RELATED SERIES OF BONDS, AND (2) MORTGAGE BONDS (EXCLUSIVE OF PLEDGED BONDS), WHICH DO NOT IN AGGREGATE PRINCIPAL AMOUNT EXCEED THE GREATER OF FIVE PERCENT (5%) OF NET TANGIBLE ASSETS OR FIVE PERCENT (5%) OF CAPITALIZATION, HAVE BEEN RETIRED THROUGH PAYMENT, REDEMPTION OR OTHERWISE (INCLUDING THOSE MORTGAGE BONDS THE PAYMENT FOR WHICH HAS BEEN PROVIDED FOR IN ACCORDANCE WITH THE MORTGAGE) AT, BEFORE OR AFTER THE MATURITY THEREOF, PROVIDED THAT

19

NO DEFAULT OR EVENT OF DEFAULT HAS OCCURRED AND IS CONTINUING (THE "RELEASE DATE"), THE RELATED SERIES OF BONDS SHALL CEASE TO SECURE THE NOTES IN ANY MANNER.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and any interest on this Note are payable or at such other offices or agencies as the Company may designate, duly endorsed by or accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Security Registrar or any transfer agent duly executed by the registered Holder hereof or his or her attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto.

Prior to due presentment for registration of transfer of this Note, the Company, the Trustee, any paying agent and any Note Registrar may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Note Registrar) for the purpose of receiving payment of or on account of the principal hereof and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any Paying Agent nor any Security Registrar shall be affected by any notice to the contrary.

The Notes of this series are issuable only in fully registered form without coupons in denominations of $1,000 and any integral multiple thereof. This Global Note is exchangeable for Notes in definitive form only under certain limited circumstances set forth in the Indenture. As provided in the Indenture and subject to certain limitations therein set forth, Notes of this series are exchangeable for a like aggregate principal amount of Notes of this series of a different authorized denomination, as requested by the registered Holder surrendering the same.

As set forth in, and subject to the provisions of, the Indenture, no Holder of any Note will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless (i) such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to the Notes of this series, (ii) the Holders of not less than 25% in principal amount of the outstanding Notes of this series shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee, (iii) the Trustee shall have failed to institute such proceeding within 60 days and (iv) the Trustee shall not have received from the Holders of a majority in principal amount of the outstanding Notes of this series a direction inconsistent with such request within such 60-day period; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of or any interest on this Note on or after the respective due dates expressed herein.

All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

25

This Note shall not be entitled to any benefit under the Indenture hereinafter referred to, be valid or become obligatory for any purpose until the Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee.

Unless the Certificate of Authentication hereon has been executed by the Trustee or a duly appointed Authentication Agent referred to herein, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Note is one of a duly authorized series of Securities of the Company (herein sometimes referred to as the "Notes"), specified in the Indenture, all issued or to be issued in one or more series under and pursuant to a Collateral Trust Indenture dated as of June 30, 1993 (the "Original Indenture") duly executed and delivered between the Company and Bank One Trust Company, National Association, as Trustee (herein referred to as the "Trustee"), as supplemented through and including a Tenth Supplemental Indenture dated as of October 23, 2002 (together with the Original Indenture, the "Indenture") between the Company and the Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the registered Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.

This Note is not subject to repayment at the option of the Holder hereof. Except as provided below, this Note is not redeemable by the Company prior to maturity and is not subject to any sinking fund.

This Note will be redeemable at the option of the Company, in whole at any time or in part from time to time, (any such date of optional redemption, an "Optional Redemption Date," which shall be a "Redemption Date" for purposes of the Indenture), at an optional redemption price (which shall be a "Redemption Price" for purposes of the Indenture) equal to the greater of (i) 100% of the principal amount of this Note to be redeemed and (ii) the sum of the present values of the principal amount of this Note to be redeemed and the remaining scheduled payments of interest on the principal amount of this Note to be redeemed (exclusive of interest accrued to the related Optional Redemption Date) until Stated Maturity, in each case discounted from their respective scheduled payment dates to such Optional Redemption Date on a semiannual basis (assuming a 360-day year consisting of 30-day months) at the Adjusted Treasury Rate (as defined below) plus 25 basis points, as determined by the Reference Treasury Dealer, plus accrued interest thereon to the date of redemption.

Notwithstanding the foregoing, installments of interest on this Note that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant Record Date.

"Adjusted Treasury Rate" means, with respect to any Optional Redemption Date, the rate per annum equal to the semiannual yield to maturity of the Comparable Treasury Issue, calculated on the third Business Day preceding such Optional Redemption Date, using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Optional Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security determined by the Reference Treasury Dealer selected by the Company as having a maturity comparable to the

26

remaining term of this Note that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity with the remaining term of this Note.

"Comparable Treasury Price" means, with respect to any Optional Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Optional Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than two such Reference Treasury Dealer Quotations, the average of all such quotations, or
(iii) if only one Reference Treasury Dealer Quotation is received, such quotation.

"Reference Treasury Dealer" means each of: (i) Barclays Capital Inc. and Salomon Smith Barney Inc. (or their respective affiliates which are Primary Treasury Dealers), and their respective successors; provided, however, that if any of the foregoing cease to be a primary U.S. Government securities dealer in The City of New York (a "Primary Treasury Dealer"), the Company shall substitute therefor another Primary Treasury Dealer; and (ii) any other Primary Treasury Dealer(s) selected by the Trustee after consultation with the Company.

"Reference Treasury Dealer Quotation" means, with respect to each Reference Treasury Dealer and any Optional Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Optional Redemption Date.

Notice of any optional redemption will be mailed at least 30 days but not more than 60 days before the Optional Redemption Date to the Holder hereof at its registered address.

Unless the Company defaults in payment of the applicable Redemption Price, on and after the applicable Redemption Date interest will cease to accrue on the principal amount of this Note called for redemption.

If money sufficient to pay the applicable Redemption Price with respect to the principal amount of and accrued interest on the principal amount of this Note to be redeemed on the applicable Redemption Date is deposited with the Trustee or Paying Agent on or before the related Redemption Date and certain other conditions are satisfied, then on or after such date, interest will cease to accrue on the principal amount of this Note called for redemption.

If the Notes are only partially redeemed by the Company, the Trustee shall select which Notes are to be redeemed in a manner it deems fair and appropriate in accordance with the terms of the Indenture.

In the event of redemption of this Note in part only, a new Note or Notes of this series for the unredeemed portion hereof will be issued in the name of the registered Holder hereof upon the cancellation hereof.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Notes may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Note upon compliance by the Company with certain conditions set forth therein.

27

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the registered Holders of not less than a majority in aggregate principal amount of the outstanding Securities of each series affected at the time, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the registered Holders of the Securities; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Securities of any series, or reduce the principal amount thereof, or reduce the rate of or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, without the consent of the registered Holder of each Security so affected or (ii) reduce the aforesaid percentage of Securities, the registered Holders of which are required to consent to any such supplemental indenture, without the consent of the registered Holders of each Security then outstanding and affected thereby. The Indenture also contains provisions permitting (i) the registered Holders of at least 66 2/3% in aggregate principal amount of the Securities of all series at the time outstanding affected thereby, on behalf of the registered Holders of the Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and (ii) the registered Holders of a majority in aggregate principal amount of the Securities of all series at the time outstanding affected thereby, on behalf of the registered Holders of the Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the registered Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such registered Holder and upon all future registered Holders and owners of this Note and of any Note issued in exchange hereof or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the time and place and at the rate and in the coin or currency herein prescribed.

Prior to the Release Date, the Notes of this series shall be secured by a series of Mortgage Bonds (the "Related Series of Bonds"), delivered by the Company to the Trustee for the benefit of the Holders of the Notes. Reference is made to the Mortgage and the Indenture for a description of the rights of the Trustee as Holder of the Related Series of Bonds, the property mortgaged and pledged under the Mortgage and the rights of the Company and of the Mortgage Trustee in respect thereof, the duties and immunities of the Mortgage Trustee and the terms and conditions upon which the Related Series of Bonds are secured and the circumstances under which additional Mortgage Bonds may be issued.

FROM AND AFTER SUCH TIME AS ALL BONDS, OTHER THAN (1) PLEDGED BONDS, INCLUDING THE RELATED SERIES OF BONDS, AND (2) MORTGAGE BONDS (EXCLUSIVE OF PLEDGED BONDS), WHICH DO NOT IN AGGREGATE PRINCIPAL AMOUNT EXCEED THE GREATER OF FIVE PERCENT (5%) OF NET TANGIBLE ASSETS OR FIVE PERCENT (5%) OF CAPITALIZATION, HAVE BEEN RETIRED THROUGH PAYMENT, REDEMPTION OR OTHERWISE (INCLUDING THOSE MORTGAGE BONDS THE PAYMENT FOR WHICH HAS BEEN PROVIDED FOR IN ACCORDANCE WITH THE MORTGAGE) AT, BEFORE OR AFTER THE MATURITY THEREOF, PROVIDED THAT NO DEFAULT OR EVENT OF DEFAULT HAS OCCURRED AND IS CONTINUING (THE

28

"RELEASE DATE"), THE RELATED SERIES OF BONDS SHALL CEASE TO SECURE THE NOTES IN ANY MANNER.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and any interest on this Note are payable or at such other offices or agencies as the Company may designate, duly endorsed by or accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Security Registrar or any transfer agent duly executed by the registered Holder hereof or his or her attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto.

Prior to due presentment for registration of transfer of this Note, the Company, the Trustee, any paying agent and any Note Registrar may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Note Registrar) for the purpose of receiving payment of or on account of the principal hereof and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any Paying Agent nor any Security Registrar shall be affected by any notice to the contrary.

The Notes of this series are issuable only in fully registered form without coupons in denominations of $1,000 and any integral multiple thereof. This Global Note is exchangeable for Notes in definitive form only under certain limited circumstances set forth in the Indenture. As provided in the Indenture and subject to certain limitations therein set forth, Notes of this series are exchangeable for a like aggregate principal amount of Notes of this series of a different authorized denomination, as requested by the registered Holder surrendering the same.

As set forth in, and subject to the provisions of, the Indenture, no Holder of any Note will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless (i) such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to the Notes of this series, (ii) the Holders of not less than 25% in principal amount of the outstanding Notes of this series shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee, (iii) the Trustee shall have failed to institute such proceeding within 60 days and (iv) the Trustee shall not have received from the Holders of a majority in principal amount of the outstanding Notes of this series a direction inconsistent with such request within such 60-day period; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of or any interest on this Note on or after the respective due dates expressed herein.

All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

(a) Each Borrowing shall be made on notice, given not later than 11:00 A.M. (New York City time) on the third Business Day prior to the date of the proposed Borrowing in the case of a Borrowing consisting of Eurodollar Rate Advances, or 10:00 A.M. (New York City time) on the Business Day of the proposed Borrowing in the case of a Borrowing consisting of Base Rate Advances, by the Borrower to the Agent, which shall give to each Lender prompt notice thereof by telecopier or telex. Each such notice of a Borrowing (a "Notice of Borrowing") shall be by telephone, confirmed immediately in writing, telecopier or telex in substantially the form of Exhibit B hereto, specifying therein the requested (i) date of such Borrowing, (ii) Type of Revolving Credit Advances comprising such Borrowing, (iii) aggregate amount of such Borrowing, and (iv) in the case of a Borrowing consisting of Eurodollar Rate Advances, initial Interest Period for each such Revolving Credit Advance.

In the case of any Borrowing that the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Revolving Credit Advance to be made by such Lender as part of such Borrowing when such Revolving Credit Advance, as a result of such failure, is not made on such date.

(d) Unless the Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Agent such Lender's ratable portion of such Borrowing, the Agent may assume that such Lender has made such portion available to the Agent on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such ratable portion available to the Agent, such Lender and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Revolving Credit Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate.

(i) all Revolving Credit Advances hereunder and (ii) all "Revolving Credit Advances" under (and as defined in) the Three-Year Agreement exceeds thirty-three percent (33%) of the aggregate amount of (x) all Commitments hereunder and (y) all "Commitments" under (and as defined in) the Three-Year Agreement then in effect on such date (or, if any of the Commitments or "Commitments" have been terminated, the aggregate amount of all Commitments and "Commitments" in effect immediately prior to such termination), the Borrower will pay to the Agent for the ratable benefit of the Lenders a utilization fee (the "Utilization Fee") at a per annum rate equal to the Applicable Utilization Fee Rate in effect from time to time payable on the aggregate outstanding amount of all Revolving Credit Advances on such date, payable in arrears quarterly on the last day of each March, June, September and December, and on the Revolving Loan Termination Date.

SECTION 2.04. Termination or Reduction of the Commitments.

(a) The Commitments shall be automatically terminated on the Revolver Termination Date.

(b) The Borrower shall have the right, upon at least three Business Days' notice to the Agent, to terminate in whole or reduce ratably in part the unused portions of the respective Commitments of the Lenders, provided that each partial reduction shall be in the aggregate amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof. Once terminated, a Commitment or portion thereof may not be reinstated.

SECTION 2.05. Repayment of Revolving Credit Advances. The Borrower shall repay to the Agent for the ratable account of the Lenders on the Revolver Termination Date the aggregate principal amount of the Revolving Credit Advances then outstanding.

SECTION 2.06. Interest on Revolving Credit Advances.

(a) Scheduled Interest. The Borrower shall pay interest on the unpaid principal amount of each Revolving Credit Advance owing to each Lender from the date of such Revolving Credit Advance until such principal amount shall be paid in full, at the following rates per annum:

(i) Base Rate Advances. During such periods as such Revolving Credit Advance is a Base Rate Advance, a rate per annum equal at all times to the sum of (x) the Base Rate in effect from time to time plus (y) the Applicable Margin in effect from time to time, payable in arrears quarterly on the last day of each March, June, September and December during such periods and on the date such Base Rate Advance shall be Converted or paid in full.

(ii) Eurodollar Rate Advances. During such periods as such Revolving Credit Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during each Interest Period for such Revolving Credit Advance to the sum of (x) the Eurodollar Rate for such Interest Period for such Revolving Credit Advance plus (y) the Applicable Margin in effect from time to time, payable in arrears on the last day of such Interest Period and, if such Interest Period has a duration of more than three months, on each day that occurs during such Interest

SIDLEY AUSTIN BROWN & WOOD LLP

15

Period every three months from the first day of such Interest Period and on the date such Eurodollar Rate Advance shall be Converted or paid in full.

(b) Default Interest. (i) Upon the occurrence and during the continuance of an Event of Default, the Borrower shall pay interest on the unpaid principal amount of each Revolving Credit Advance owing to each Lender, payable in arrears on the dates referred to in clause (a)(i) or (a)(ii) above, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on such Revolving Credit Advance pursuant to clause (a)(i) or (a)(ii) above, and (ii) the Borrower shall pay, to the fullest extent permitted by law, the amount of any interest, fee or other amount payable hereunder that is not paid when due, from the date such amount shall be due until such amount shall be paid in full, payable in arrears on the date such amount shall be paid in full and on demand, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on Base Rate Advances pursuant to clause (a)(i) above.

SECTION 2.07. Interest Rate Determination.

(a) Each Reference Bank agrees to furnish to the Agent timely information for the purpose of determining each Eurodollar Rate. If any one or more of the Reference Banks shall not furnish such timely information to the Agent for the purpose of determining any such interest rate, the Agent shall determine such interest rate on the basis of timely information furnished by the remaining Reference Banks. The Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Agent for purposes of Section 2.06(a)(i) or (ii), and the rate, if any, furnished by each Reference Bank for the purpose of determining the interest rate under Section 2.06(a)(ii).

(b) If, with respect to any Eurodollar Rate Advances, the Required Lenders notify the Agent that the Eurodollar Rate for any Interest Period for such Eurodollar Rate Advances will not adequately reflect the cost to such Required Lenders of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period, the Agent shall forthwith so notify the Borrower and the Lenders, whereupon (i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance, and (ii) the obligation of the Lenders to make, or to Convert Revolving Credit Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

(c) If the Borrower shall fail to select the duration of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of "Interest Period" in Section 1.01, the Agent will forthwith so notify the Borrower and the Lenders and such Eurodollar Rate Advances will automatically, on the last day of the then existing Interest Period therefor, Convert into Base Rate Advances.

(d) On the date on which the aggregate unpaid principal amount of Eurodollar Rate Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $5,000,000, such Eurodollar Rate Advances shall automatically Convert into Base Rate Advances.

SIDLEY AUSTIN BROWN & WOOD LLP

16

(e) Upon the occurrence and during the continuance of any Event of Default, (i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make, or to Convert Revolving Credit Advances into, Eurodollar Rate Advances shall be suspended.

(f) If fewer than two Reference Banks furnish timely information to the Agent for determining the Eurodollar Rate for any Eurodollar Rate Advances:

(i) the Agent shall forthwith notify the Borrower and the Lenders that the interest rate cannot be determined for such Eurodollar Rate Advances,

(ii) with respect to Eurodollar Rate Advances, each such Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance (or if such Eurodollar Rate Advance is then a Base Rate Advance, will continue as a Base Rate Advance), and

(iii) the obligation of the Lenders to make Eurodollar Rate Advances or to Convert Revolving Credit Advances into Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

SECTION 2.08. Optional Conversion of Revolving Credit Advances. The Borrower may on any Business Day, upon notice given to the Agent not later than 11:00 A.M. (New York City time) on the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.07 and 2.11, Convert all Revolving Credit Advances of one Type comprising the same Borrowing into Revolving Credit Advances of the other Type (it being understood that such Conversion of a Revolving Credit Advance or of its Interest Period does not constitute a repayment or prepayment of such Revolving Credit Advance); provided, however, that any Conversion of Eurodollar Rate Advances into Base Rate Advances shall be made only on the last day of an Interest Period for such Eurodollar Rate Advances, any Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in an amount not less than the minimum amount specified in Section 2.02(b) and no Conversion of any Revolving Credit Advances shall result in more separate Borrowings than permitted under Section 2.02(b). Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Revolving Credit Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the initial Interest Period for each such Eurodollar Rate Advance. Each notice of Conversion shall be irrevocable and binding on the Borrower.

SECTION 2.09. Prepayments of Revolving Credit Advances.

(a) Optional Prepayment. The Borrower may on any Business Day, upon notice given to the Agent not later than 11:00 A.M. (New York City time),
(i) on the same day for Base Rate Advances and (ii) on the second Business Day prior to the prepayment in the case of Eurodollar Rate Advances stating the proposed date and aggregate principal amount of the prepayment (and if such notice is given the Borrower shall) prepay the outstanding principal amount of the Revolving Credit Advances comprising part of the same Borrowing in whole or

SIDLEY AUSTIN BROWN & WOOD LLP

17

ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that (x) each partial prepayment shall be in an aggregate principal amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in the event of any such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.04(c).

(b) Mandatory Prepayment. The Borrower shall, upon five Business Days notice from the Agent given at the request or with the consent of the Required Lenders, prepay the aggregate principal amount outstanding plus all interest thereon and all other amounts payable hereunder or under the Notes, in the event that: (i) any Person or two or more Persons acting in concert (other than DTE Energy or any of its Subsidiaries) shall have acquired beneficial ownership (within the meaning of Rule 13d-3 of the Securities and Exchange Commission under the Securities Exchange Act of 1934), directly or indirectly, of Voting Stock of the Borrower (or other securities convertible into such Voting Stock) representing 20% or more of the combined voting power of all Voting Stock of the Borrower; or (ii) any Person or two or more Persons acting in concert (other than DTE Energy or any of its Subsidiaries) shall have acquired by contract or otherwise, or shall have entered into a contract or arrangement that, upon consummation, will result in its or their acquisition of the power to exercise, directly or indirectly, a controlling influence over the management or policies of the Borrower.

SECTION 2.10. Increased Costs.

(a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to any Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Advances (excluding for purposes of this Section 2.10 any such increased costs resulting from (i) Taxes or Other Taxes (as to which Section 2.13 shall govern) and (ii) changes in the basis of taxation of overall net income or overall gross income by the United States or by the foreign jurisdiction or state under the laws of which such Lender is organized or has its Applicable Lending Office or any political subdivision thereof), then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower and the Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error.

(b) If any Lender determines that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender and that the amount of such capital is increased by or based upon the existence of such Lender's commitment to lend hereunder and other commitments of this type, then, upon demand by such Lender (with a copy of such demand to the Agent), the Borrower shall pay to the Agent for the account of such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender or such corporation in the light of such circumstances, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of

SIDLEY AUSTIN BROWN & WOOD LLP

18

such Lender's commitment to lend hereunder. A certificate as to such amounts submitted to the Borrower and the Agent by such Lender shall be conclusive and binding for all purposes, absent manifest error.

(c) In the event that a Lender demands payment from the Borrower for amounts owing pursuant to subsection (a) or (b) of this Section 2.10, the Borrower may, upon payment of such amounts and subject to the requirements of Sections 8.04 and 8.07, substitute for such Lender another financial institution, which financial institution shall be an Eligible Assignee and shall assume the Commitments of such Lender and purchase the Revolving Credit Advances held by such Lender in accordance with Section 8.07, provided, however, that (i) no Default shall have occurred and be continuing, (ii) the Borrower shall have satisfied all of its obligations in connection with the Loan Documents with respect to such Lender, and (iii) if such assignee is not a Lender, (A) such assignee is acceptable to the Agent and (B) the Borrower shall have paid the Agent a $3,000 administrative fee.

SECTION 2.11. Illegality. Notwithstanding any other provision of this Agreement, if any Lender shall notify the Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for any Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, (i) each Eurodollar Rate Advance will automatically, upon such demand, Convert into a Base Rate Advance or a Revolving Credit Advance that bears interest at the rate set forth in Section 2.06(a)(i), as the case may be, and (ii) the obligation of the Lenders to make Eurodollar Rate Advances or to Convert Revolving Credit Advances into Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

SECTION 2.12. Payments and Computations.

(a) The Borrower shall make each payment hereunder and under the Notes not later than 11:00 A.M. (New York City time) on the day when due in U.S. dollars to the Agent at the Agent's Account in same day funds and without set off, deduction or counterclaim. The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest, facility fees or the Utilization Fee ratably (other than amounts payable pursuant to Section 2.10, 2.13 or 8.04(c)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to
Section 8.07(c), from and after the effective date specified in such Assignment and Acceptance, the Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder or under the Note held by such Lender, to

SIDLEY AUSTIN BROWN & WOOD LLP

19

charge from time to time against any or all of the Borrower's accounts with such Lender any amount so due.

(c) All computations of interest based on the Base Rate shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate or the Federal Funds Rate and of facility fees and the Utilization Fee shall be made by the Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest, facility fees or the Utilization Fee are payable. Each determination by the Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest, facility fee or the Utilization Fee, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Agent, each Lender shall repay to the Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Agent, at the Federal Funds Rate.

SECTION 2.13. Taxes.

(a) Any and all payments by the Borrower hereunder or under the Notes shall be made, in accordance with Section 2.12, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender and the Agent, taxes imposed on its overall net income, and franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction under the laws of which such Lender or the Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Lender, taxes imposed on its overall net income, and franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction of such Lender's Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under the Notes being hereinafter referred to as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Lender or the Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.13) such Lender or the Agent (as the

SIDLEY AUSTIN BROWN & WOOD LLP

20

case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or under the Notes or from the execution, delivery or registration of, performing under, or otherwise with respect to, this Agreement or the Notes (hereinafter referred to as "Other Taxes").

(c) The Borrower shall indemnify each Lender and the Agent for the full amount of Taxes or Other Taxes (including, without limitation, any taxes imposed by any jurisdiction on amounts payable under this Section 2.13) imposed on or paid by such Lender or the Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date such Lender or the Agent (as the case may be) makes written demand therefor.

(d) Within 30 days after the date of any payment of Taxes, the Borrower shall furnish to the Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing payment thereof. In the case of any payment hereunder or under the Notes by or on behalf of the Borrower through an account or branch outside the United States or by or on behalf of the Borrower by a payor that is not a United States person, if the Borrower determines that no Taxes are payable in respect thereof, the Borrower shall furnish, or shall cause such payor to furnish, to the Agent, at such address, an opinion of counsel acceptable to the Agent stating that such payment is exempt from Taxes. For purposes of this subsection (d) and subsection (e), the terms "United States" and "United States person" shall have the meanings specified in
Section 7701 of the Internal Revenue Code.

(e) Each Lender organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Lender and on the date of the Assignment and Acceptance pursuant to which it becomes a Lender in the case of each other Lender, and from time to time thereafter as requested in writing by the Borrower (but only so long as such Lender remains lawfully able to do so), shall provide each of the Agent and the Borrower with two original Internal Revenue Service Form W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that such Lender is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or the Notes. If the forms provided by a Lender at the time such Lender first becomes a party to this Agreement indicates a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Lender provides the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such form; provided, however, that, if at the date of the Assignment and Acceptance pursuant to which a Lender assignee becomes a party to this Agreement, the Lender assignor was entitled to payments under subsection (a) in respect of United States withholding tax with respect to interest paid at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the

SIDLEY AUSTIN BROWN & WOOD LLP

21

future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to the Lender assignee on such date. If any form or document referred to in this subsection (e) requires the disclosure of information, other than information necessary to compute the tax payable and information required on the date hereof by Internal Revenue Service Form W-8BEN or W-8ECI, that the Lender reasonably considers to be confidential, the Lender shall give notice thereof to the Borrower and shall not be obligated to include in such form or document such confidential information.

(f) For any period with respect to which a Lender has failed to provide the Borrower with the appropriate form described in Section 2.13(e) (other than if such failure is due to a change in law occurring subsequent to the date on which a form originally was required to be provided, or if such form otherwise is not required under the first sentence of subsection (e) above), such Lender shall not be entitled to indemnification under Section 2.13(a) or
(c) with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should a Lender become subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as the Lender shall reasonably request to assist the Lender to recover such Taxes.

(g) In the event that a Lender demands payment from the Borrower for amounts owing pursuant to subsection (a) or (b) of this Section 2.13, the Borrower may, upon payment of such amounts and subject to the requirements of Sections 8.04 and 8.07, substitute for such Lender another financial institution, which financial institution shall be an Eligible Assignee and shall assume the Commitments of such Lender and purchase the Revolving Credit Advances held by such Lender in accordance with Section 8.07, provided, however, that (i) no Default shall have occurred and be continuing, (ii) the Borrower shall have satisfied all of its obligations in connection with the Loan Documents with respect to such Lender, and (iii) if such assignee is not a Lender, (A) such assignee is acceptable to the Agent and (B) the Borrower shall have paid the Agent a $3,000 administrative fee.

SECTION 2.14. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Revolving Credit Advances owing to it (other than pursuant to Section 2.10, 2.13 or 8.04(c)) in excess of its ratable share of payments on account of the Revolving Credit Advances obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Revolving Credit Advances owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender's ratable share (according to the proportion of (i) the amount of such Lender's required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.14 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

SIDLEY AUSTIN BROWN & WOOD LLP

SECTION 2.15. Use of Proceeds. The proceeds of the Revolving Credit Advances shall be available (and the Borrower agrees that it shall use such proceeds) solely for general corporate purposes, including commercial paper liquidity, of the Borrower and its Subsidiaries.

SECTION 2.16. Extensions of Revolver Termination Date. No earlier than 45 days and no later than 30 days prior to the Revolver Termination Date in effect at any time, the Borrower may, by written notice to the Agent, request that such Revolver Termination Date be extended for a period of 364 days. Such request shall be irrevocable and binding upon the Borrower. The Agent shall promptly notify each Lender of such request. If a Lender agrees, in its individual and sole discretion, to so extend its Commitment (an "Extending Lender"), it shall deliver to the Agent a written notice of its agreement to do so no earlier than 30 days and no later than 20 days prior to such Revolver Termination Date and the Agent shall notify the Borrower of such Extending Lender's agreement to extend its Commitment no later than 15 days prior to such Revolver Termination Date. The Commitment of any Lender that fails to accept or respond to the Borrower's request for extension of the Revolver Termination Date (a "Declining Lender") shall be terminated on the Revolver Termination Date originally in effect (without regard to any extension by other Lenders) and on such Revolver Termination Date the Borrower shall pay in full the principal amount of all Revolving Credit Advances owing to such Declining Lender, together with accrued interest thereon to the date of such payment of principal and all other amounts payable to such Declining Lender under this Agreement. The Agent shall promptly notify each Extending Lender of the aggregate Commitments of the Declining Lenders. The Extending Lenders, or any of them, may offer to increase their respective Commitments by an aggregate amount up to the aggregate amount of the Declining Lenders' Commitments and any such Extending Lender shall deliver to the Agent a notice of its offer to so increase its Commitment no later than 15 days prior to such Revolver Termination Date. To the extent of any shortfall in the aggregate amount of extended Commitments, the Borrower shall have the right to require any Declining Lender to assign in full its rights and obligations under this Agreement to an Eligible Assignee designated by the Borrower and acceptable to the Agent, that agrees to accept all of such rights and obligations (a "Replacement Lender"), provided that (i) such increase and/or such assignment is otherwise in compliance with Section 8.07 (provided that the $3,000 processing and recording fee in respect of such assignment shall be payable by the Borrower), (ii) such Declining Lender receives payment in full of the principal amount of all Revolving Credit Advances owing to such Declining Lender, together with accrued interest thereon to the date of such payment of principal and all other amounts payable to such Declining Lender under this Agreement, and (iii) any such increase shall be effective on the Revolver Termination Date in effect at the time the Borrower requests such extension and any such assignment shall be effective on the date specified by the Borrower and agreed to by the Replacement Lender and the Agent. If Extending Lenders and Replacement Lenders provide Commitments in an aggregate amount at least equal to 51% of the aggregate amount of the Commitments outstanding 30 days prior to the Revolver Termination Date in effect at the time the Borrower requests such extension, the Revolver Termination Date shall be extended by 364 days for such Extending Lenders.

SECTION 2.17. Noteless Agreement; Evidence of Indebtedness.

(a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Revolving Credit Advance made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(b) The Agent shall also maintain accounts in which it will record (i) the date and the amount of each Revolving Credit Advance made hereunder and the Interest Period, if any, applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, (iii) the effective date and amount of each Assignment and Acceptance delivered to and accepted by it and the parties thereto pursuant to Section 8.07, (iv) the amount of any sum received by the Agent hereunder from the Borrower and each Lender's share thereof, and (v) all other appropriate debits and credits as provided in this Agreement, including, without limitation, all fees, charges, expenses and interest.

(c) The entries maintained in the accounts maintained pursuant to clauses (a) and (b) above shall be prima facie evidence of the existence and amounts of the obligations hereunder and under the Notes therein recorded; provided, however, that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay such obligations in accordance with their terms.

(d) Any Lender may request that its Revolving Credit Advances be evidenced by a promissory note representing its Revolving Credit Advances substantially in the form of Exhibit A (each, a "Note"). In such event, the Borrower shall prepare, execute and deliver to such Lender such Note payable to the order of such Lender. Thereafter, the Revolving Credit Advances evidenced by each such Note and interest thereon shall at all times (including after any assignment pursuant to Section 8.07) be represented by one or more Notes payable to the order of the payee named therein or any assignee pursuant to Section 8.07, except to the extent that any such Lender or assignee subsequently returns any such Note for cancellation and requests that such Revolving Credit Advances once again be evidenced as described in clauses (a) and (b) above.

(e) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Revolving Credit Advances, or the number of Lenders, that shall be required for the Lenders or any of them to take any action hereunder or (f) amend this Section 8.01; and provided further that no amendment, waiver or consent shall, unless in writing and signed by the Agent in addition to the Lenders required above to take such action, affect the rights or duties of the Agent under this Agreement or any Note.

SECTION 8.02. Notices, Etc. All notices and other communications provided for hereunder shall be in writing (including telecopier, telegraphic or telex communication) and mailed, telecopied, telegraphed, telexed or delivered, if to the Borrower, at its address at 2000 2nd Avenue, Detroit, MI 48226, Attention: Treasurer; if to any Initial Lender, at its Domestic Lending Office specified opposite its name on Schedule I hereto; if to any other Lender, at its Domestic Lending Office specified in the Assignment and Acceptance pursuant to which it became a Lender; and if to the Agent, at its address at 222 Broadway, New York, NY 10038, Attention: Michele Fuimo and Mayerlin Jaramillo; or, as to the Borrower or the Agent, at such other address as shall be designated by such party in a written notice to the other parties and, as to each other party, at such other address as shall be designated by such party in a written notice to the Borrower and the Agent.

SIDLEY AUSTIN BROWN & WOOD LLP

37

communications to the Agent pursuant to Article II, III or VII shall not be effective until received by the Agent. Delivery by telecopier of an executed counterpart of any amendment or waiver of any provision of this Agreement or the Notes or of any Exhibit hereto to be executed and delivered hereunder shall be effective as delivery of a manually executed counterpart thereof.

SECTION 8.03. No Waiver; Remedies. No failure on the part of any Lender or the Agent to exercise, and no delay in exercising, any right hereunder or under any Note shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 8.04. Costs and Expenses.

(a) The Borrower agrees to pay on demand, upon presentation of a statement of account and absent manifest error, all reasonable costs and reasonable expenses of the Agent in connection with the preparation, execution, delivery, administration, modification and amendment of this Agreement, the Notes, each other Loan Document and the other documents to be delivered hereunder and thereunder, including, without limitation, (A) all due diligence, syndication (including printing, distribution and bank meetings), transportation, computer, duplication, appraisal, consultant, and audit expenses and (B) the reasonable fees and reasonable expenses of counsel for the Agent with respect thereto and with respect to advising the Agent as to its rights and responsibilities under the Loan Documents. The Borrower further agrees to pay on demand all reasonable costs and reasonable expenses of the Agent and the Lenders, if any (including, without limitation, reasonable internal and external counsel fees and expenses, provided such fees and expenses are not duplicative), in connection with the "workout", restructuring or enforcement (whether through negotiations, legal proceedings or otherwise) of this Agreement, the Notes and the other documents to be delivered hereunder, including, without limitation, reasonable fees and expenses of counsel for the Agent and each Lender in connection with the enforcement of rights under this Section 8.04(a).

(b) The Borrower agrees to indemnify, to the extent legally permissible, and hold harmless the Agent and each Lender and each of their Affiliates and their officers, directors, employees, agents and advisors (each, an "Indemnified Party") from and against any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of, or in connection with the preparation for a defense of, any investigation, litigation or proceeding arising out of, related to or in connection with (i) the Notes, this Agreement, the other Loan Documents any of the transactions contemplated herein or therein or the actual or proposed use of the proceeds of the Revolving Credit Advances or (ii) the actual or alleged presence of Hazardous Materials on any property of the Borrower or any of its Subsidiaries or any Environmental Action relating in any way to the Borrower or any of its Subsidiaries, in each case whether or not such investigation, litigation or proceeding is brought by the Borrower, its directors, shareholders or creditors or an Indemnified Party or any other Person or any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party's gross negligence or

SIDLEY AUSTIN BROWN & WOOD LLP

38

willful misconduct. The Borrower also agrees not to assert any claim against the Agent, any Lender, any of their Affiliates, or any of their respective directors, officers, employees, attorneys and agents, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to the Notes, this Agreement, the other Loan Documents any of the transactions contemplated herein or therein or the actual or proposed use of the proceeds of the Revolving Credit Advances.

(c) If any payment of principal of, or Conversion of, any Eurodollar Rate Advance is made by the Borrower to or for the account of a Lender other than on the last day of the Interest Period for such Revolving Credit Advance, as a result of a payment or Conversion pursuant to Section 2.07(d) or (e), 2.09 or 2.11, acceleration of the maturity of the Revolving Credit Advances pursuant to Section 6.01, or for any other reason, the Borrower shall, upon demand by such Lender (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, costs or expenses that it may reasonably incur as a result of such payment or Conversion, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Revolving Credit Advance.

(d) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in Sections 2.10, 2.13 and 8.04 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the Notes.

SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Agent to declare the Revolving Credit Advances due and payable pursuant to the provisions of Section 6.01, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender or such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under the Loan Documents and any Note held by such Lender, whether or not such Lender shall have made any demand under this Agreement or such Note and although such obligations may be unmatured. Each Lender agrees promptly to notify the Borrower after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender and its Affiliates under this
Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Lender and its Affiliates may have.

SECTION 8.06. Binding Effect. This Agreement shall become effective (other than Section 2.01, which shall only become effective upon satisfaction of the conditions precedent set forth in Section 3.01) when it shall have been executed by the Borrower and the Agent and when the Agent shall have been notified by each Initial Lender that such Initial Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the Agent and each Lender and their respective successors and assigns, except that the

SIDLEY AUSTIN BROWN & WOOD LLP

39

Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders to any Person.

SECTION 8.07. Assignments, Designations and Participations.
(a) Each Lender may, with the prior consent of the Agent (which consent shall not be unreasonably withheld) and (for so long as no Default has occurred and is continuing) the Borrower (which consent shall not be unreasonably withheld) assign to one or more Persons all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Revolving Credit Advances owed to it and any Note or Notes held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all rights and obligations under this Agreement and, for so long as no Default has occurred and is continuing, shall be made concurrently with an assignment in a ratable amount of such Lender's rights and obligations under the Three-Year Agreement (including, without limitation, all or a portion of its "Commitment", "Revolving Credit Advances" owed to it and any "Note" or "Notes" held by it under (and as each such term is defined in) the Three-Year Agreement), (ii) except in the case of an assignment to a Person that, immediately prior to such assignment, was a Lender or an assignment of all of a Lender's rights and obligations under this Agreement, the amount of the Commitment of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $10,000,000 or an integral multiple of $1,000,000 in excess thereof, (iii) each such assignment shall be to an Eligible Assignee, and (iv) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with any Note subject to such assignment and a processing and recordation fee of $3,000. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto).

(b) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any lien or security interest created or purported to be created under or in connection with, this Agreement or any other instrument or document furnished pursuant hereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in

SIDLEY AUSTIN BROWN & WOOD LLP

40

Section 4.01 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement as are delegated to the Agent by the terms hereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Lender.

(c) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with any Note or Notes subject to such assignment, the Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to the Borrower. Within five Business Days after the Borrower's receipt of such notice, if requested by the applicable Lender, the Borrower, at its own expense, shall execute and deliver to the Agent in exchange for the surrendered Note a new Note to the order of such Eligible Assignee in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and, if the assigning Lender has retained a Commitment hereunder, if requested by such assigning Lender, a new Note to the order of the assigning Lender in an amount equal to the Commitment retained by it hereunder. Such new Note or Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Note or Notes, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of Exhibit A hereto.

(d) The Agent shall maintain at its address referred to in
Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses and Commitment of, and principal amount of Revolving Credit Advances owing to, each Lender from time to time (the "Register"). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(e) Each Lender may sell participations to one or more banks or other entities (other than the Borrower or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Revolving Credit Advances owing to it and any Note or Notes held by it); provided, however, that
(i) such Lender's obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the owner of such Revolving Credit Advances for all purposes of this Agreement, (iv) the Borrower, the Agent and the other Lenders shall continue to

SIDLEY AUSTIN BROWN & WOOD LLP

41

deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and (v) no participant under any such participation shall have any right to approve any amendment or waiver of any provision of this Agreement or any Note, or any consent to any departure by the Borrower therefrom, except to the extent that such amendment, waiver or consent would (A) reduce the principal of, or interest on, the Revolving Credit Advances or any fees or other amounts payable hereunder, or (B) increase the Commitments, in each case to the extent subject to such participation, or postpone any date fixed for any payment of principal of, or interest on, the Revolving Credit Advances or any fees or other amounts payable hereunder, in each case to the extent subject to such participation. Each participant shall be entitled to the benefits of Sections 2.10, 2.11 and 2.13 to the same extent as if it were a Lender and had acquired its interest under this Agreement by an assignment made pursuant to this Section 8.07, provided, however, that in no event shall the Borrower be obligated to make any payment with respect to such Sections that is greater than the amount that the Borrower would have otherwise made had no participations been sold under this Section 8.07(e).

(f) Any Lender may, in connection with any assignment, designation or participation or proposed assignment, designation or participation pursuant to this Section 8.07, disclose to the assignee, designee or participant or proposed assignee, designee or participant, any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any such disclosure, the assignee, designee or participant or proposed assignee, designee or participant shall agree to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Lender.

(g) Notwithstanding any other provision set forth in this Agreement, any Lender may at any time (i) create a security interest in all or a portion of its rights under this Agreement (including, without limitation, the Revolving Credit Advances owing to it and the Note or Notes held by it) in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System or (ii) with notice to the Agent and the Borrower, assign all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Revolving Credit Advances owed to it and the Note or Notes held by it) to any of its Affiliates.

(h) Notwithstanding anything to the contrary contained herein, any Lender (a "Designating Lender") may grant to one or more special purpose funding vehicles (each an "SPV"), identified as such in writing from time to time by the Designating Lender to the Agent and the Borrower, the option to provide to the Borrower all or any part of any Revolving Credit Advance that such Designating Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPV to make any Revolving Credit Advance, (ii) if an SPV elects not to exercise such option or otherwise fails to provide all or any part of such Revolving Credit Advance, the Designating Lender shall be obligated to make such Revolving Credit Advance pursuant to the terms hereof, (iii) the Designating Lender shall remain liable for any indemnity or other payment obligation with respect to its Commitment hereunder and (iv) no SPV or Designating Lender shall be entitled to receive any greater amount under this Agreement than the Designating Lender would have been entitled to receive had the Designating Lender not otherwise granted such SPV the option to provide any Revolving Credit Advance to the Borrower. The making of a Revolving Credit Advance by an SPV hereunder shall utilize the Commitment of the Designating Lender to

SIDLEY AUSTIN BROWN & WOOD LLP

42

the same extent, and as if, such Revolving Credit Advance were made by such Designating Lender.

(i) Each party hereto hereby acknowledges and agrees that no SPV shall have the rights of a Lender hereunder, such rights being retained by the applicable Designating Lender. Accordingly, and without limiting the foregoing, each party hereby further acknowledges and agrees that no SPV shall have any voting rights hereunder and that the voting rights attributable to any Revolving Credit Advance made by an SPV shall be exercised only by the relevant Designating Lender and that each Designating Lender shall serve as the administrative agent and attorney-in-fact for its SPV and shall on behalf of its SPV receive any and all payments made for the benefit of such SPV and take all actions hereunder to the extent, if any, such SPV shall have any rights hereunder. No additional Note shall be required to evidence the Revolving Credit Advances or portion thereof made by an SPV; and the related Designating Lender shall be deemed to hold its Note or Notes, if any, as administrative agent for such SPV to the extent of the Revolving Credit Advances or portion thereof funded by such SPV. In addition, any payments for the account of any SPV shall be paid to its Designating Lender as administrative agent for such SPV.

(j) Each party hereto hereby agrees that no SPV shall be liable for any indemnity or payment under this Agreement for which a Lender would otherwise be liable so long as, and to the extent that, the related Designating Lender provides such indemnity or makes such payment; provided, with respect to such agreement by the Borrower that the related Designating Lender shall not be in breach of its obligation to make Revolving Credit Advances to the Borrower hereunder. In furtherance of the foregoing, each party hereto hereby agrees (which agreements shall survive the termination of this Agreement) that prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPV, it will not institute against, or join any other person in instituting against, such SPV any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof; provided, with respect to such agreement by the Borrower that the related Designating Lender shall not be in breach of its obligation to make Revolving Credit Advances to the Borrower hereunder. Notwithstanding the foregoing, the Designating Lender unconditionally agrees to indemnify the Borrower, the Agent and each Lender against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be incurred by or asserted against the Borrower, the Agent or such Lender, as the case may be, in any way relating to or arising as a consequence of any such forbearance or delay in the initiation of any such proceeding against its SPV.

(k) In addition, notwithstanding anything to the contrary contained in subsection 8.07(h), (i), (j) or (k) or otherwise in this Agreement, any SPV may (i) at any time and without paying any processing fee therefor, assign or participate all or a portion of its interest in any Revolving Credit Advances to the Designating Lender or to any financial institutions providing liquidity and/or credit support to or for the account of such SPV to support the funding or maintenance of Revolving Credit Advances and (ii) disclose on a confidential basis any non-public information relating to its Revolving Credit Advances to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancements to such SPV.

SIDLEY AUSTIN BROWN & WOOD LLP

43

Subsection 8.07(h), (i), (j) or (k) may not be amended without the written consent of any Designating Lender affected thereby.

SECTION 8.08. Confidentiality. Neither the Agent nor any Lender shall disclose any Confidential Information to any other Person without the consent of the Borrower, other than (a) to the Agent's or such Lender's Affiliates and their officers, directors, employees, agents and advisors and, as contemplated by Section 8.07(f), to actual or prospective assignees and participants, and then only on a confidential basis, (b) as required by any law, rule or regulation or judicial process, (c) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Lender and (d) as requested or required by any state, federal or foreign authority or examiner regulating banks or banking.

SECTION 8.09. Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 8.10. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 8.11. Jurisdiction, Etc.

(a) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the Notes, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement or the Notes in the courts of any jurisdiction.

(b) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the Notes in any New York State or federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

SIDLEY AUSTIN BROWN & WOOD LLP

44

SECTION 8.12. Waiver of Jury Trial. Each of the Borrower, the Agent and the Lenders hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the Notes or the actions of the Agent or any Lender in the negotiation, administration, performance or enforcement thereof.

"Level III Status" exists at any date if, on such date, (i) the Borrower has not qualified for Level I Status or Level II Status and (ii) the Borrower's Moody's Rating is Baa2 or better or the Borrower's S&P Rating is BBB or better.

"Level IV Status" exists at any date if, on such date, (i) the Borrower has not qualified for Level I Status, Level II Status or Level III Status and (ii) the Borrower's Moody's Rating is Baa3 or better or the Borrower's S&P Rating is BBB- or better.

"Status" means Level I Status, Level II Status, Level III Status, Level IV Status or Level V Status.

The Applicable Margin, Applicable Utilization Fee and Applicable Percentage shall be determined in accordance with the foregoing table based on the Borrower's Status as determined from its then-current Moody's Rating and S&P Rating. The credit rating in effect on any date for the purposes of this Schedule is that in effect at the close of business on such date. If at any time the Borrower does not have both a Moody's Rating and an S&P Rating, Level V Status shall exist.

In the event that a split occurs between the two ratings, then the Status corresponding to the lower of the two ratings shall apply. However, if the split is greater than one level, then the pricing shall be based upon the Status one level above the Status corresponding to the lower of the two ratings.

FORM OF OPINION OF COUNSEL TO THE BORROWER

[Date]

To each of the Lenders set forth
in Schedule A hereto

DTE Energy Company
The Detroit Edison Company
Michigan Consolidated Gas Company

Ladies and Gentlemen:

This opinion is furnished to you pursuant to (i) Section 3.01(h)(v) of each of the 364-Day and Three-Year Credit Agreements, dated as of October 25, 2002, among DTE Energy Company ("DTE"), the financial institutions from time to time parties thereto (the "DTE Lenders"), and Citibank, N.A., as agent for said DTE Lenders, Barclays Bank PLC and Banc One Capital Markets, Inc., as Co-Syndication Agents, and with Salomon Smith Barney Inc., as Lead Arranger and Sole Book Runner (the "DTE Credit Agreements"), (ii) Section 3.01(h)(v) of each of the 364-Day and Three-Year Credit Agreements, dated as of October 25, 2002, among The Detroit Edison Company ("DECO"), the financial institutions parties thereto (the "DECO Lenders") and Barclays Bank PLC, as agent for said DECO Lenders, Salomon Smith Barney Inc. and Banc One Capital Markets, Inc., as Co-Syndication Agents, and with Barclays Capital and Banc One Capital Markets, Inc., as Co-Lead Arrangers and Joint Book Runners (the "DECO Credit Agreements"), and (iii) Section 3.01(h)(v) of each of the 364-Day and Three-Year Credit Agreements, dated as of October 25, 2002, among Michigan Consolidated Gas Company ("MichCon"), the financial institutions parties thereto (the "MichCon Lenders", and together with the DTE Lenders and the DECO Lenders, the "Lenders") and Bank One, NA, as agent for said Lenders, Barclays Bank PLC and Salomon Smith Barney Inc., as Co-Syndication Agents, and with Banc One Capital Markets, Inc. and Barclays Capital, as Co-Lead Arrangers and Joint Book Runners (the "MichCon Credit Agreements", and together with the DTE Credit Agreements and the DECO Credit Agreements, the "Credit Agreements"). Terms defined in each Credit Agreement are used herein as therein defined.

I am the Associate General Counsel of DTE, and the Vice President and General Counsel of both DECO and MichCon, and have acted as counsel for each of the Borrowers in connection with the preparation, execution and delivery of the Loan Documents.

In that connection, I, in conjunction with the members of my staff, have examined:

(i) Each Loan Document, executed by each of the parties thereto.

SIDLEY AUSTIN BROWN & WOOD LLP

16

(ii) The other documents furnished by each of the Borrowers pursuant to Article III of each of the Credit Agreements.

(iii) The Restated Articles of Incorporation of DTE, the Restated Articles of Incorporation of DECO, and the Restated Articles of Incorporation of MichCon and all amendments thereto (the "Charters").

(iv) The By-Laws of each of the Borrowers and all amendments thereto (the "By-Laws").

(v) Certificates from the State of Michigan attesting to the continued corporate existence and good standing of each of the Borrowers.

I have also examined the originals, or copies certified to my satisfaction, of the documents listed in a certificate of a Financial Officer of each of the Borrowers, dated the date hereof (the "Certificate"), certifying that the documents listed in such certificate are all of the indentures, loan or credit agreements, leases, guarantees, mortgages, security agreements, bonds, notes and other agreements or instruments, and all of the orders, writs, judgments, awards, injunctions and decrees, that affect or purport to affect each Borrower's right to borrow money or each Borrower's obligations under the Loan Documents to which it is party. In addition, I have examined the originals, copies certified to my satisfaction, of such other corporate records of each Borrower, certificates of public officials and of officers of each Borrower, and agreements, instruments and other documents, as we have deemed necessary as a basis for the opinions expressed below. As to questions of fact material to such opinions, I have, when relevant facts were not independently established by me, relied upon certificates of public officials. I have assumed the due execution and delivery, pursuant to due authorization, of each of the Credit Agreements by the Lenders and the applicable Agent.

My opinions expressed below are limited to the law of the State of Michigan and the federal law of the United States.

Based upon the foregoing and upon such investigation as I have deemed necessary, I am of the following opinion:

1. Each of the Borrowers is a corporation duly organized, validly existing and in good standing under the laws of the State of Michigan.

2. The execution, delivery and performance by each of the Borrowers of the Loan Documents to which it is party, and the consummation of the transactions contemplated thereby, are within each Borrower's corporate powers, have been duly authorized by all necessary corporate action, and do not contravene (i) the Charters or the By-Laws of each Borrower or (ii) any law, rule or regulation applicable to each of the Borrowers (including, without limitation, Regulation X of the Board of Governors of the Federal Reserve System) or (iii) any contractual or legal restriction contained in any document listed in the Certificate or, to the best of my knowledge (after due inquiry), contained in any other similar document.

3. No authorization, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body or any other third party is required for the due

SIDLEY AUSTIN BROWN & WOOD LLP

17

execution, delivery, recordation, filing or performance by each Borrower of the Loan Documents to which each is a party, except such as have been obtained, including, in the case of DECO, the orders of the Federal Energy Regulatory Commission.

4. Each Loan Document has been duly executed and delivered on behalf of the Borrower thereto.

5. Except as may have been disclosed to you in the SEC Reports designated in the Certificate, to the best of my knowledge (after due inquiry) there are no pending or overtly threatened actions or proceedings affecting each Borrower or any of its Subsidiaries before any court, governmental agency or arbitrator that (i) could be reasonably likely to have a Material Adverse Effect or (ii) purport to affect the legality, validity, binding effect or enforceability of any Loan Documents or the consummation of the transactions contemplated thereby.

6. In a properly presented case, a Michigan court or a federal court sitting in the State of Michigan applying Michigan choice of law rules should give effect to the choice of law provisions of the Loan Documents and should hold that such Loan Documents are to be governed by the laws of the State of New York rather than the laws of the State of Michigan. In rendering the foregoing opinion, I note that by their terms the Loan Documents expressly select New York law as the laws governing their interpretation and that the Loan Documents governed by New York law were delivered by the parties thereto to the Agent in New York. The choice of law provisions of the Loan Documents are not voidable under the laws of the State of Michigan.

7. If, despite the provisions of Section 8.09 of each of the Credit Agreements wherein the parties thereto agree that the Loan Documents shall be governed by, and construed in accordance with, the laws of the State of New York, a court of the State of Michigan or a federal court sitting in the State of Michigan were to hold that the Loan Documents are governed by, and to be construed in accordance with the laws of the State of Michigan, the respective Loan Documents would be, under the laws of the State of Michigan, legal, valid and binding obligations of the applicable Borrower, enforceable against such Borrower in accordance with their respective terms.

8. Neither the Borrowers nor any of their Subsidiaries is an "investment company," or an "affiliated person" of, or "promoter" or "principal underwriter" for, an "investment company," as such terms are defined in the Investment Company Act of 1940, as amended; DECO is a "public utility company" and a "subsidiary company" of DTE, which is a "holding company" as such terms are defined in the Public Utility Holding Company Act of 1935, as amended (the "1935 Act"), and such "holding company" and DECO are currently exempt from the provisions of the 1935 Act (except Section 9 thereof); and MichCon is a "public utility company" and a "subsidiary company" of MichCon Holdings, Inc., which is a "holding company" and a "subsidiary company" of DTE Enterprises, Inc., which is a "holding company" and a "subsidiary company" of DTE, as such terms are defined in the 1935 Act, and such "holding companies" and MichCon are currently exempt from the provisions of the 1935 Act (except Section 9 thereof);

SIDLEY AUSTIN BROWN & WOOD LLP

18

The opinions set forth above are subject to the following qualifications:

(a) My opinion in paragraph 7 above as to enforceability is subject to the effect of any applicable bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar law affecting creditors' rights generally.

(b) My opinion in paragraph 7 above as to enforceability is subject to the effect of general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether considered in a proceeding in equity or at law).

(c) I express no opinion as to participation and the effect of the law of any jurisdiction other than the State of Michigan wherein any Lender may be located or wherein enforcement of the Loan Documents may be sought that limits the rates of interest legally chargeable or collectible.

Very truly yours,

(a) Each Borrowing shall be made on notice, given not later than 11:00 A.M. (New York City time) on the third Business Day prior to the date of the proposed Borrowing in the case of a Borrowing consisting of Eurodollar Rate Advances, or 10:00 A.M. (New York City time) on the Business Day of the proposed Borrowing in the case of a Borrowing consisting of Base Rate Advances, by the Borrower to the Agent, which shall give to each Lender prompt notice thereof by telecopier or telex. Each such notice of a Borrowing (a "Notice of Borrowing") shall be by telephone, confirmed immediately in writing, telecopier or telex in substantially the form of Exhibit B hereto, specifying therein the requested (i) date of such Borrowing, (ii) Type of Revolving Credit Advances comprising such Borrowing, (iii) aggregate amount of such Borrowing, and (iv) in the case of a Borrowing consisting of Eurodollar Rate Advances, initial Interest Period for each such Revolving Credit Advance. Each Lender shall, before 12:00 noon (New York City time) on the date of such Borrowing, make available for the account of its Applicable Lending Office to the Agent at the Agent's Account, in same day funds, such Lender's ratable portion of such Borrowing. After the Agent's receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will make such funds available to the Borrower at the Agent's address referred to in Section 8.02.

(b) Anything in subsection (a) above to the contrary notwithstanding, (i) the Borrower may not select Eurodollar Rate Advances for any Borrowing if the aggregate amount of such Borrowing is less than $5,000,000 or if the obligation of the Lenders to make Eurodollar Rate Advances shall then be suspended pursuant to Section 2.07 or 2.11 and (ii) at no time shall the sum of (x) all Borrowings comprising Eurodollar Rate Advances outstanding hereunder and (y) all "Borrowings" comprising "Eurodollar Rate Advances" outstanding under, and as such terms are defined in, the 364-Day Agreement, be greater than ten.

(c) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing that the related Notice of Borrowing specifies is to be

13 SIDLEY AUSTIN BROWN & WOOD LLP


comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Revolving Credit Advance to be made by such Lender as part of such Borrowing when such Revolving Credit Advance, as a result of such failure, is not made on such date.

(d) Unless the Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Agent such Lender's ratable portion of such Borrowing, the Agent may assume that such Lender has made such portion available to the Agent on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such ratable portion available to the Agent, such Lender and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Revolving Credit Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Lender's Revolving Credit Advance as part of such Borrowing for purposes of this Agreement.

(e) The failure of any Lender to make the Revolving Credit Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Revolving Credit Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Revolving Credit Advance to be made by such other Lender on the date of any Borrowing.

SECTION 2.03. Fees.

(a) Facility Fee. The Borrower agrees to pay to the Agent for the account of each Lender a facility fee (the "Facility Fee") on the aggregate amount of such Lender's Commitment from the date hereof in the case of each Initial Lender and from effective date specified in the Assignment and Acceptance pursuant to which it became a Lender in the case of each other Lender until all of the Revolving Credit Advances have been paid in full and the Commitments under this Agreement have been terminated at a rate per annum equal to the Applicable Percentage in effect from time to time, payable in arrears quarterly on the last day of each March, June, September and December, and on the Revolving Loan Termination Date.

(b) Agent's Fees. The Borrower shall pay to the Agent for its own account such fees as may from time to time be agreed between the Borrower and the Agent.

(c) Utilization Fee. If the aggregate outstanding amount of
(i) all Revolving Credit Advances hereunder and (ii) all "Revolving Credit Advances" under (and as defined in) the 364-Day Agreement exceeds thirty-three percent (33%) of the aggregate amount of (x) all

14 SIDLEY AUSTIN BROWN & WOOD LLP


Commitments hereunder and (y) all "Commitments" under (and as defined in) the 364-Day Agreement then in effect on such date (or, if any of the Commitments or "Commitments" have been terminated, the aggregate amount of all Commitments and "Commitments" in effect immediately prior to such termination), the Borrower will pay to the Agent for the ratable benefit of the Lenders a utilization fee (the "Utilization Fee") at a per annum rate equal to the Applicable Utilization Fee Rate in effect from time to time payable on the aggregate outstanding amount of all Revolving Credit Advances on such date, payable in arrears quarterly on the last day of each March, June, September and December, and on the Revolving Loan Termination Date.

SECTION 2.04. Termination or Reduction of the Commitments.

(a) The Commitments shall be automatically terminated on the Revolver Termination Date.

(b) The Borrower shall have the right, upon at least three Business Days' notice to the Agent, to terminate in whole or reduce ratably in part the unused portions of the respective Commitments of the Lenders, provided that each partial reduction shall be in the aggregate amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof. Once terminated, a Commitment or portion thereof may not be reinstated.

SECTION 2.05. Repayment of Revolving Credit Advances. The Borrower shall repay to the Agent for the ratable account of the Lenders on the Revolver Termination Date the aggregate principal amount of the Revolving Credit Advances then outstanding.

SECTION 2.06. Interest on Revolving Credit Advances.

(a) Scheduled Interest. The Borrower shall pay interest on the unpaid principal amount of each Revolving Credit Advance owing to each Lender from the date of such Revolving Credit Advance until such principal amount shall be paid in full, at the following rates per annum:

(i) Base Rate Advances. During such periods as such Revolving Credit Advance is a Base Rate Advance, a rate per annum equal at all times to the sum of (x) the Base Rate in effect from time to time plus (y) the Applicable Margin in effect from time to time, payable in arrears quarterly on the last day of each March, June, September and December during such periods and on the date such Base Rate Advance shall be Converted or paid in full.

(ii) Eurodollar Rate Advances. During such periods as such Revolving Credit Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during each Interest Period for such Revolving Credit Advance to the sum of (x) the Eurodollar Rate for such Interest Period for such Revolving Credit Advance plus (y) the Applicable Margin in effect from time to time, payable in arrears on the last day of such Interest Period and, if such Interest Period has a duration of more than three months, on each day that occurs during such Interest Period every three months from the first day of such Interest Period and on the date such Eurodollar Rate Advance shall be Converted or paid in full.

15 SIDLEY AUSTIN BROWN & WOOD LLP


(b) Default Interest. (i) Upon the occurrence and during the continuance of an Event of Default, the Borrower shall pay interest on the unpaid principal amount of each Revolving Credit Advance owing to each Lender, payable in arrears on the dates referred to in clause (a)(i) or (a)(ii) above, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on such Revolving Credit Advance pursuant to clause (a)(i) or (a)(ii) above, and (ii) the Borrower shall pay, to the fullest extent permitted by law, the amount of any interest, fee or other amount payable hereunder that is not paid when due, from the date such amount shall be due until such amount shall be paid in full, payable in arrears on the date such amount shall be paid in full and on demand, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on Base Rate Advances pursuant to clause (a)(i) above.

SECTION 2.07. Interest Rate Determination.

(a) Each Reference Bank agrees to furnish to the Agent timely information for the purpose of determining each Eurodollar Rate. If any one or more of the Reference Banks shall not furnish such timely information to the Agent for the purpose of determining any such interest rate, the Agent shall determine such interest rate on the basis of timely information furnished by the remaining Reference Banks. The Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Agent for purposes of Section 2.06(a)(i) or (ii), and the rate, if any, furnished by each Reference Bank for the purpose of determining the interest rate under Section 2.06(a)(ii).

(b) If, with respect to any Eurodollar Rate Advances, the Required Lenders notify the Agent that the Eurodollar Rate for any Interest Period for such Eurodollar Rate Advances will not adequately reflect the cost to such Required Lenders of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period, the Agent shall forthwith so notify the Borrower and the Lenders, whereupon (i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance, and (ii) the obligation of the Lenders to make, or to Convert Revolving Credit Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

(c) If the Borrower shall fail to select the duration of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of "Interest Period" in Section 1.01, the Agent will forthwith so notify the Borrower and the Lenders and such Eurodollar Rate Advances will automatically, on the last day of the then existing Interest Period therefor, Convert into Base Rate Advances.

(d) On the date on which the aggregate unpaid principal amount of Eurodollar Rate Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $5,000,000, such Eurodollar Rate Advances shall automatically Convert into Base Rate Advances.

(e) Upon the occurrence and during the continuance of any Event of Default, (i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest

16 SIDLEY AUSTIN BROWN & WOOD LLP


Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make, or to Convert Revolving Credit Advances into, Eurodollar Rate Advances shall be suspended.

(f) If fewer than two Reference Banks furnish timely information to the Agent for determining the Eurodollar Rate for any Eurodollar Rate Advances:

(i) the Agent shall forthwith notify the Borrower and the Lenders that the interest rate cannot be determined for such Eurodollar Rate Advances,

(ii) with respect to Eurodollar Rate Advances, each such Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance (or if such Eurodollar Rate Advance is then a Base Rate Advance, will continue as a Base Rate Advance), and

(iii) the obligation of the Lenders to make Eurodollar Rate Advances or to Convert Revolving Credit Advances into Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

SECTION 2.08. Optional Conversion of Revolving Credit Advances. The Borrower may on any Business Day, upon notice given to the Agent not later than 11:00 A.M. (New York City time) on the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.07 and 2.11, Convert all Revolving Credit Advances of one Type comprising the same Borrowing into Revolving Credit Advances of the other Type (it being understood that such Conversion of a Revolving Credit Advance or of its Interest Period does not constitute a repayment or prepayment of such Revolving Credit Advance); provided, however, that any Conversion of Eurodollar Rate Advances into Base Rate Advances shall be made only on the last day of an Interest Period for such Eurodollar Rate Advances, any Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in an amount not less than the minimum amount specified in Section 2.02(b) and no Conversion of any Revolving Credit Advances shall result in more separate Borrowings than permitted under Section 2.02(b). Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Revolving Credit Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the initial Interest Period for each such Eurodollar Rate Advance. Each notice of Conversion shall be irrevocable and binding on the Borrower.

SECTION 2.09. Prepayments of Revolving Credit Advances.

(a) Optional Prepayment. The Borrower may on any Business Day, upon notice given to the Agent not later than 11:00 A.M. (New York City time),
(i) on the same day for Base Rate Advances and (ii) on the second Business Day prior to the prepayment in the case of Eurodollar Rate Advances stating the proposed date and aggregate principal amount of the prepayment (and if such notice is given the Borrower shall) prepay the outstanding principal amount of the Revolving Credit Advances comprising part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that (x) each partial prepayment shall be in an aggregate

17 SIDLEY AUSTIN BROWN & WOOD LLP


principal amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in the event of any such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.04(c).

(b) Mandatory Prepayment. The Borrower shall, upon five Business Days notice from the Agent given at the request or with the consent of the Required Lenders, prepay the aggregate principal amount outstanding plus all interest thereon and all other amounts payable hereunder or under the Notes, in the event that: (i) any Person or two or more Persons acting in concert (other than DTE Energy or any of its Subsidiaries) shall have acquired beneficial ownership (within the meaning of Rule 13d-3 of the Securities and Exchange Commission under the Securities Exchange Act of 1934), directly or indirectly, of Voting Stock of the Borrower (or other securities convertible into such Voting Stock) representing 20% or more of the combined voting power of all Voting Stock of the Borrower; or (ii) any Person or two or more Persons acting in concert (other than DTE Energy or any of its Subsidiaries) shall have acquired by contract or otherwise, or shall have entered into a contract or arrangement that, upon consummation, will result in its or their acquisition of the power to exercise, directly or indirectly, a controlling influence over the management or policies of the Borrower.

SECTION 2.10. Increased Costs.

(a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to any Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Advances (excluding for purposes of this Section 2.10 any such increased costs resulting from (i) Taxes or Other Taxes (as to which Section 2.13 shall govern) and (ii) changes in the basis of taxation of overall net income or overall gross income by the United States or by the foreign jurisdiction or state under the laws of which such Lender is organized or has its Applicable Lending Office or any political subdivision thereof), then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower and the Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error.

(b) If any Lender determines that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender and that the amount of such capital is increased by or based upon the existence of such Lender's commitment to lend hereunder and other commitments of this type, then, upon demand by such Lender (with a copy of such demand to the Agent), the Borrower shall pay to the Agent for the account of such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender or such corporation in the light of such circumstances, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender's commitment to lend hereunder. A certificate as to such amounts submitted to the

18 SIDLEY AUSTIN BROWN & WOOD LLP


Borrower and the Agent by such Lender shall be conclusive and binding for all purposes, absent manifest error.

(c) In the event that a Lender demands payment from the Borrower for amounts owing pursuant to subsection (a) or (b) of this Section 2.10, the Borrower may, upon payment of such amounts and subject to the requirements of Sections 8.04 and 8.07, substitute for such Lender another financial institution, which financial institution shall be an Eligible Assignee and shall assume the Commitments of such Lender and purchase the Revolving Credit Advances held by such Lender in accordance with Section 8.07, provided, however, that (i) no Default shall have occurred and be continuing, (ii) the Borrower shall have satisfied all of its obligations in connection with the Loan Documents with respect to such Lender, and (iii) if such assignee is not a Lender, (A) such assignee is acceptable to the Agent and (B) the Borrower shall have paid the Agent a $3,000 administrative fee.

SECTION 2.11. Illegality. Notwithstanding any other provision of this Agreement, if any Lender shall notify the Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for any Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, (i) each Eurodollar Rate Advance will automatically, upon such demand, Convert into a Base Rate Advance or a Revolving Credit Advance that bears interest at the rate set forth in Section 2.06(a)(i), as the case may be, and (ii) the obligation of the Lenders to make Eurodollar Rate Advances or to Convert Revolving Credit Advances into Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

SECTION 2.12. Payments and Computations.

(a) The Borrower shall make each payment hereunder and under the Notes not later than 11:00 A.M. (New York City time) on the day when due in U.S. dollars to the Agent at the Agent's Account in same day funds and without set off, deduction or counterclaim. The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest, facility fees or the Utilization Fee ratably (other than amounts payable pursuant to Section 2.10, 2.13 or 8.04(c)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to
Section 8.07(c), from and after the effective date specified in such Assignment and Acceptance, the Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder or under the Note held by such Lender, to

19 SIDLEY AUSTIN BROWN & WOOD LLP


charge from time to time against any or all of the Borrower's accounts with such Lender any amount so due.

(c) All computations of interest based on the Base Rate shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate or the Federal Funds Rate and of facility fees and the Utilization Fee shall be made by the Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest, facility fees or the Utilization Fee are payable. Each determination by the Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest, facility fee or the Utilization Fee, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Agent, each Lender shall repay to the Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Agent, at the Federal Funds Rate.

SECTION 2.13. Taxes.

(a) Any and all payments by the Borrower hereunder or under the Notes shall be made, in accordance with Section 2.12, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender and the Agent, taxes imposed on its overall net income, and franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction under the laws of which such Lender or the Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Lender, taxes imposed on its overall net income, and franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction of such Lender's Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under the Notes being hereinafter referred to as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Lender or the Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.13) such Lender or the Agent (as the

20 SIDLEY AUSTIN BROWN & WOOD LLP


case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or under the Notes or from the execution, delivery or registration of, performing under, or otherwise with respect to, this Agreement or the Notes (hereinafter referred to as "Other Taxes").

(c) The Borrower shall indemnify each Lender and the Agent for the full amount of Taxes or Other Taxes (including, without limitation, any taxes imposed by any jurisdiction on amounts payable under this Section 2.13) imposed on or paid by such Lender or the Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date such Lender or the Agent (as the case may be) makes written demand therefor.

(d) Within 30 days after the date of any payment of Taxes, the Borrower shall furnish to the Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing payment thereof. In the case of any payment hereunder or under the Notes by or on behalf of the Borrower through an account or branch outside the United States or by or on behalf of the Borrower by a payor that is not a United States person, if the Borrower determines that no Taxes are payable in respect thereof, the Borrower shall furnish, or shall cause such payor to furnish, to the Agent, at such address, an opinion of counsel acceptable to the Agent stating that such payment is exempt from Taxes. For purposes of this subsection (d) and subsection (e), the terms "United States" and "United States person" shall have the meanings specified in
Section 7701 of the Internal Revenue Code.

(e) Each Lender organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Lender and on the date of the Assignment and Acceptance pursuant to which it becomes a Lender in the case of each other Lender, and from time to time thereafter as requested in writing by the Borrower (but only so long as such Lender remains lawfully able to do so), shall provide each of the Agent and the Borrower with two original Internal Revenue Service Form W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that such Lender is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or the Notes. If the forms provided by a Lender at the time such Lender first becomes a party to this Agreement indicates a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Lender provides the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such form; provided, however, that, if at the date of the Assignment and Acceptance pursuant to which a Lender assignee becomes a party to this Agreement, the Lender assignor was entitled to payments under subsection (a) in respect of United States withholding tax with respect to interest paid at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the

21 SIDLEY AUSTIN BROWN & WOOD LLP


future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to the Lender assignee on such date. If any form or document referred to in this subsection (e) requires the disclosure of information, other than information necessary to compute the tax payable and information required on the date hereof by Internal Revenue Service Form W-8BEN or W-8ECI, that the Lender reasonably considers to be confidential, the Lender shall give notice thereof to the Borrower and shall not be obligated to include in such form or document such confidential information.

(f) For any period with respect to which a Lender has failed to provide the Borrower with the appropriate form described in Section 2.13(e) (other than if such failure is due to a change in law occurring subsequent to the date on which a form originally was required to be provided, or if such form otherwise is not required under the first sentence of subsection (e) above), such Lender shall not be entitled to indemnification under Section 2.13(a) or
(c) with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should a Lender become subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as the Lender shall reasonably request to assist the Lender to recover such Taxes.

(g) In the event that a Lender demands payment from the Borrower for amounts owing pursuant to subsection (a) or (b) of this Section 2.13, the Borrower may, upon payment of such amounts and subject to the requirements of Sections 8.04 and 8.07, substitute for such Lender another financial institution, which financial institution shall be an Eligible Assignee and shall assume the Commitments of such Lender and purchase the Revolving Credit Advances held by such Lender in accordance with Section 8.07, provided, however, that (i) no Default shall have occurred and be continuing, (ii) the Borrower shall have satisfied all of its obligations in connection with the Loan Documents with respect to such Lender, and (iii) if such assignee is not a Lender, (A) such assignee is acceptable to the Agent and (B) the Borrower shall have paid the Agent a $3,000 administrative fee.

SECTION 2.14. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Revolving Credit Advances owing to it (other than pursuant to Section 2.10, 2.13 or 8.04(c)) in excess of its ratable share of payments on account of the Revolving Credit Advances obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Revolving Credit Advances owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender's ratable share (according to the proportion of (i) the amount of such Lender's required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.14 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

22 SIDLEY AUSTIN BROWN & WOOD LLP


SECTION 2.15. Use of Proceeds. The proceeds of the Revolving Credit Advances shall be available (and the Borrower agrees that it shall use such proceeds) solely for general corporate purposes, including commercial paper liquidity, of the Borrower and its Subsidiaries.

SECTION 2.16. Reserved.

SECTION 2.17. Noteless Agreement; Evidence of Indebtedness.

(a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Revolving Credit Advance made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(b) The Agent shall also maintain accounts in which it will record (i) the date and the amount of each Revolving Credit Advance made hereunder and the Interest Period, if any, applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, (iii) the effective date and amount of each Assignment and Acceptance delivered to and accepted by it and the parties thereto pursuant to Section 8.07, (iv) the amount of any sum received by the Agent hereunder from the Borrower and each Lender's share thereof, and (v) all other appropriate debits and credits as provided in this Agreement, including, without limitation, all fees, charges, expenses and interest.

(c) The entries maintained in the accounts maintained pursuant to clauses (a) and (b) above shall be prima facie evidence of the existence and amounts of the obligations hereunder and under the Notes therein recorded; provided, however, that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay such obligations in accordance with their terms.

(d) Any Lender may request that its Revolving Credit Advances be evidenced by a promissory note representing its Revolving Credit Advances substantially in the form of Exhibit A (each, a "Note"). In such event, the Borrower shall prepare, execute and deliver to such Lender such Note payable to the order of such Lender. Thereafter, the Revolving Credit Advances evidenced by each such Note and interest thereon shall at all times (including after any assignment pursuant to Section 8.07) be represented by one or more Notes payable to the order of the payee named therein or any assignee pursuant to Section 8.07, except to the extent that any such Lender or assignee subsequently returns any such Note for cancellation and requests that such Revolving Credit Advances once again be evidenced as described in clauses (a) and (b) above.

The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Agent's giving of notice of resignation or the Required Lenders' removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $50,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Agent's resignation or removal hereunder as Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

ARTICLE VIII

MISCELLANEOUS

SECTION 8.01. Amendments, Etc. No amendment or waiver of any provision of this Agreement or the Notes, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Required Lenders, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no amendment, waiver or consent shall, unless in writing and signed by all the Lenders, do any of the following: (a) waive any of the conditions specified in Section 3.01, (b) increase the Commitments of the Lenders or subject the Lenders to any additional obligations,
(c) reduce the principal of, or interest on, the Revolving Credit Advances or any fees or other amounts payable hereunder, (d) postpone any date fixed for any payment of principal of, or interest on, the Revolving Credit Advances or any fees or other amounts payable hereunder, (e) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Revolving Credit Advances, or the number of Lenders, that shall be required for the Lenders or any of them to take any action hereunder or (f) amend this Section 8.01; and provided further that no amendment, waiver or consent shall, unless in writing and signed by the Agent in addition to the Lenders required above to take such action, affect the rights or duties of the Agent under this Agreement or any Note.

SECTION 8.02. Notices, Etc. All notices and other communications provided for hereunder shall be in writing (including telecopier, telegraphic or telex communication) and mailed, telecopied, telegraphed, telexed or delivered, if to the Borrower, at its address at 2000 2nd Avenue, Detroit, MI 48226, Attention: Treasurer; if to any Initial Lender, at its

36 SIDLEY AUSTIN BROWN & WOOD LLP


Domestic Lending Office specified opposite its name on Schedule I hereto; if to any other Lender, at its Domestic Lending Office specified in the Assignment and Acceptance pursuant to which it became a Lender; and if to the Agent, at its address at 222 Broadway, New York, NY 10038, Attention: Michele Fuimo and Mayerlin Jaramillo; or, as to the Borrower or the Agent, at such other address as shall be designated by such party in a written notice to the other parties and, as to each other party, at such other address as shall be designated by such party in a written notice to the Borrower and the Agent. All such notices and communications shall, when mailed, telecopied, telegraphed or telexed, be effective when deposited in the mails, telecopied, delivered to the telegraph company or confirmed by telex answerback, respectively, except that notices and communications to the Agent pursuant to Article II, III or VII shall not be effective until received by the Agent. Delivery by telecopier of an executed counterpart of any amendment or waiver of any provision of this Agreement or the Notes or of any Exhibit hereto to be executed and delivered hereunder shall be effective as delivery of a manually executed counterpart thereof.

SECTION 8.03. No Waiver; Remedies. No failure on the part of any Lender or the Agent to exercise, and no delay in exercising, any right hereunder or under any Note shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 8.04. Costs and Expenses.

(a) The Borrower agrees to pay on demand, upon presentation of a statement of account and absent manifest error, all reasonable costs and reasonable expenses of the Agent in connection with the preparation, execution, delivery, administration, modification and amendment of this Agreement, the Notes, each other Loan Document and the other documents to be delivered hereunder and thereunder, including, without limitation, (A) all due diligence, syndication (including printing, distribution and bank meetings), transportation, computer, duplication, appraisal, consultant, and audit expenses and (B) the reasonable fees and reasonable expenses of counsel for the Agent with respect thereto and with respect to advising the Agent as to its rights and responsibilities under the Loan Documents. The Borrower further agrees to pay on demand all reasonable costs and reasonable expenses of the Agent and the Lenders, if any (including, without limitation, reasonable internal and external counsel fees and expenses, provided such fees and expenses are not duplicative), in connection with the "workout", restructuring or enforcement (whether through negotiations, legal proceedings or otherwise) of this Agreement, the Notes and the other documents to be delivered hereunder, including, without limitation, reasonable fees and expenses of counsel for the Agent and each Lender in connection with the enforcement of rights under this Section 8.04(a).

(b) The Borrower agrees to indemnify, to the extent legally permissible, and hold harmless the Agent and each Lender and each of their Affiliates and their officers, directors, employees, agents and advisors (each, an "Indemnified Party") from and against any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of, or in connection with the preparation for a defense of, any investigation, litigation or proceeding arising out of, related to or in connection with (i) the Notes, this Agreement, the other Loan Documents any of the transactions contemplated herein or therein or the actual or proposed use of the proceeds of the

37 SIDLEY AUSTIN BROWN & WOOD LLP


Revolving Credit Advances or (ii) the actual or alleged presence of Hazardous Materials on any property of the Borrower or any of its Subsidiaries or any Environmental Action relating in any way to the Borrower or any of its Subsidiaries, in each case whether or not such investigation, litigation or proceeding is brought by the Borrower, its directors, shareholders or creditors or an Indemnified Party or any other Person or any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party's gross negligence or willful misconduct. The Borrower also agrees not to assert any claim against the Agent, any Lender, any of their Affiliates, or any of their respective directors, officers, employees, attorneys and agents, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to the Notes, this Agreement, the other Loan Documents any of the transactions contemplated herein or therein or the actual or proposed use of the proceeds of the Revolving Credit Advances.

(c) If any payment of principal of, or Conversion of, any Eurodollar Rate Advance is made by the Borrower to or for the account of a Lender other than on the last day of the Interest Period for such Revolving Credit Advance, as a result of a payment or Conversion pursuant to Section 2.07(d) or (e), 2.09 or 2.11, acceleration of the maturity of the Revolving Credit Advances pursuant to Section 6.01, or for any other reason, the Borrower shall, upon demand by such Lender (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, costs or expenses that it may reasonably incur as a result of such payment or Conversion, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Revolving Credit Advance.

(d) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in Sections 2.10, 2.13 and 8.04 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the Notes.

SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Agent to declare the Revolving Credit Advances due and payable pursuant to the provisions of Section 6.01, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender or such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under the Loan Documents and any Note held by such Lender, whether or not such Lender shall have made any demand under this Agreement or such Note and although such obligations may be unmatured. Each Lender agrees promptly to notify the Borrower after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender and its Affiliates under this
Section are in addition to other rights and remedies

38 SIDLEY AUSTIN BROWN & WOOD LLP


(including, without limitation, other rights of set-off) that such Lender and its Affiliates may have.

SECTION 8.06. Binding Effect. This Agreement shall become effective (other than Section 2.01, which shall only become effective upon satisfaction of the conditions precedent set forth in Section 3.01) when it shall have been executed by the Borrower and the Agent and when the Agent shall have been notified by each Initial Lender that such Initial Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the Agent and each Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders to any Person.

SECTION 8.07. Assignments, Designations and Participations.
(a) Each Lender may, with the prior consent of the Agent (which consent shall not be unreasonably withheld) and (for so long as no Default has occurred and is continuing) the Borrower (which consent shall not be unreasonably withheld) assign to one or more Persons all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Revolving Credit Advances owed to it and any Note or Notes held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all rights and obligations under this Agreement and, for so long as no Default has occurred and is continuing, shall be made concurrently with an assignment in a ratable amount of such Lender's rights and obligations under the 364-Day Agreement (including, without limitation, all or a portion of its "Commitment", "Revolving Credit Advances" owed to it and any "Note" or "Notes" held by it under (and as each such term is defined in) the 364-Day Agreement), (ii) except in the case of an assignment to a Person that, immediately prior to such assignment, was a Lender or an assignment of all of a Lender's rights and obligations under this Agreement, the amount of the Commitment of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $10,000,000 or an integral multiple of $1,000,000 in excess thereof, (iii) each such assignment shall be to an Eligible Assignee, and (iv) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with any Note subject to such assignment and a processing and recordation fee of $3,000. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto).

(b) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender makes no representation or warranty and assumes no responsibility with

39 SIDLEY AUSTIN BROWN & WOOD LLP


respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any lien or security interest created or purported to be created under or in connection with, this Agreement or any other instrument or document furnished pursuant hereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement as are delegated to the Agent by the terms hereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Lender.

(c) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with any Note or Notes subject to such assignment, the Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to the Borrower. Within five Business Days after the Borrower's receipt of such notice, if requested by the applicable Lender, the Borrower, at its own expense, shall execute and deliver to the Agent in exchange for the surrendered Note a new Note to the order of such Eligible Assignee in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and, if the assigning Lender has retained a Commitment hereunder, if requested by such assigning Lender, a new Note to the order of the assigning Lender in an amount equal to the Commitment retained by it hereunder. Such new Note or Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Note or Notes, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of Exhibit A hereto.

(d) The Agent shall maintain at its address referred to in
Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses and Commitment of, and principal amount of Revolving Credit Advances owing to, each Lender from time to time (the "Register"). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

40 SIDLEY AUSTIN BROWN & WOOD LLP


(e) Each Lender may sell participations to one or more banks or other entities (other than the Borrower or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Revolving Credit Advances owing to it and any Note or Notes held by it); provided, however, that
(i) such Lender's obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the owner of such Revolving Credit Advances for all purposes of this Agreement, (iv) the Borrower, the Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and (v) no participant under any such participation shall have any right to approve any amendment or waiver of any provision of this Agreement or any Note, or any consent to any departure by the Borrower therefrom, except to the extent that such amendment, waiver or consent would (A) reduce the principal of, or interest on, the Revolving Credit Advances or any fees or other amounts payable hereunder, or (B) increase the Commitments, in each case to the extent subject to such participation, or postpone any date fixed for any payment of principal of, or interest on, the Revolving Credit Advances or any fees or other amounts payable hereunder, in each case to the extent subject to such participation. Each participant shall be entitled to the benefits of Sections 2.10, 2.11 and 2.13 to the same extent as if it were a Lender and had acquired its interest under this Agreement by an assignment made pursuant to this Section 8.07, provided, however, that in no event shall the Borrower be obligated to make any payment with respect to such Sections that is greater than the amount that the Borrower would have otherwise made had no participations been sold under this Section 8.07(e).

(f) Any Lender may, in connection with any assignment, designation or participation or proposed assignment, designation or participation pursuant to this Section 8.07, disclose to the assignee, designee or participant or proposed assignee, designee or participant, any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any such disclosure, the assignee, designee or participant or proposed assignee, designee or participant shall agree to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Lender.

(g) Notwithstanding any other provision set forth in this Agreement, any Lender may at any time (i) create a security interest in all or a portion of its rights under this Agreement (including, without limitation, the Revolving Credit Advances owing to it and the Note or Notes held by it) in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System or (ii) with notice to the Agent and the Borrower, assign all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Revolving Credit Advances owed to it and the Note or Notes held by it) to any of its Affiliates.

(h) Notwithstanding anything to the contrary contained herein, any Lender (a "Designating Lender") may grant to one or more special purpose funding vehicles (each an "SPV"), identified as such in writing from time to time by the Designating Lender to the Agent and the Borrower, the option to provide to the Borrower all or any part of any Revolving Credit Advance that such Designating Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by

41 SIDLEY AUSTIN BROWN & WOOD LLP


any SPV to make any Revolving Credit Advance, (ii) if an SPV elects not to exercise such option or otherwise fails to provide all or any part of such Revolving Credit Advance, the Designating Lender shall be obligated to make such Revolving Credit Advance pursuant to the terms hereof, (iii) the Designating Lender shall remain liable for any indemnity or other payment obligation with respect to its Commitment hereunder and (iv) no SPV or Designating Lender shall be entitled to receive any greater amount under this Agreement than the Designating Lender would have been entitled to receive had the Designating Lender not otherwise granted such SPV the option to provide any Revolving Credit Advance to the Borrower. The making of a Revolving Credit Advance by an SPV hereunder shall utilize the Commitment of the Designating Lender to the same extent, and as if, such Revolving Credit Advance were made by such Designating Lender.

(i) Each party hereto hereby acknowledges and agrees that no SPV shall have the rights of a Lender hereunder, such rights being retained by the applicable Designating Lender. Accordingly, and without limiting the foregoing, each party hereby further acknowledges and agrees that no SPV shall have any voting rights hereunder and that the voting rights attributable to any Revolving Credit Advance made by an SPV shall be exercised only by the relevant Designating Lender and that each Designating Lender shall serve as the administrative agent and attorney-in-fact for its SPV and shall on behalf of its SPV receive any and all payments made for the benefit of such SPV and take all actions hereunder to the extent, if any, such SPV shall have any rights hereunder. No additional Note shall be required to evidence the Revolving Credit Advances or portion thereof made by an SPV; and the related Designating Lender shall be deemed to hold its Note or Notes, if any, as administrative agent for such SPV to the extent of the Revolving Credit Advances or portion thereof funded by such SPV. In addition, any payments for the account of any SPV shall be paid to its Designating Lender as administrative agent for such SPV.

(j) Each party hereto hereby agrees that no SPV shall be liable for any indemnity or payment under this Agreement for which a Lender would otherwise be liable so long as, and to the extent that, the related Designating Lender provides such indemnity or makes such payment; provided, with respect to such agreement by the Borrower that the related Designating Lender shall not be in breach of its obligation to make Revolving Credit Advances to the Borrower hereunder. In furtherance of the foregoing, each party hereto hereby agrees (which agreements shall survive the termination of this Agreement) that prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPV, it will not institute against, or join any other person in instituting against, such SPV any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof; provided, with respect to such agreement by the Borrower that the related Designating Lender shall not be in breach of its obligation to make Revolving Credit Advances to the Borrower hereunder. Notwithstanding the foregoing, the Designating Lender unconditionally agrees to indemnify the Borrower, the Agent and each Lender against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be incurred by or asserted against the Borrower, the Agent or such Lender, as the case may be, in any way relating to or arising as a consequence of any such forbearance or delay in the initiation of any such proceeding against its SPV.

42 SIDLEY AUSTIN BROWN & WOOD LLP


(k) In addition, notwithstanding anything to the contrary contained in subsection 8.07(h), (i), (j) or (k) or otherwise in this Agreement, any SPV may (i) at any time and without paying any processing fee therefor, assign or participate all or a portion of its interest in any Revolving Credit Advances to the Designating Lender or to any financial institutions providing liquidity and/or credit support to or for the account of such SPV to support the funding or maintenance of Revolving Credit Advances and (ii) disclose on a confidential basis any non-public information relating to its Revolving Credit Advances to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancements to such SPV. Subsection 8.07(h), (i), (j) or (k) may not be amended without the written consent of any Designating Lender affected thereby.

SECTION 8.08. Confidentiality. Neither the Agent nor any Lender shall disclose any Confidential Information to any other Person without the consent of the Borrower, other than (a) to the Agent's or such Lender's Affiliates and their officers, directors, employees, agents and advisors and, as contemplated by Section 8.07(f), to actual or prospective assignees and participants, and then only on a confidential basis, (b) as required by any law, rule or regulation or judicial process, (c) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Lender and (d) as requested or required by any state, federal or foreign authority or examiner regulating banks or banking.

SECTION 8.09. Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 8.10. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 8.11. Jurisdiction, Etc.

(a) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the Notes, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement or the Notes in the courts of any jurisdiction.

43 SIDLEY AUSTIN BROWN & WOOD LLP


(b) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the Notes in any New York State or federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

SECTION 8.12. Waiver of Jury Trial. Each of the Borrower, the Agent and the Lenders hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the Notes or the actions of the Agent or any Lender in the negotiation, administration, performance or enforcement thereof.

"Level III Status" exists at any date if, on such date, (i) the Borrower has not qualified for Level I Status or Level II Status and (ii) the Borrower's Moody's Rating is Baa2 or better or the Borrower's S&P Rating is BBB or better.

"Level IV Status" exists at any date if, on such date, (i) the Borrower has not qualified for Level I Status, Level II Status or Level III Status and (ii) the Borrower's Moody's Rating is Baa3 or better or the Borrower's S&P Rating is BBB- or better.

                  The Applicable Margin, Applicable Utilization Fee and

If at any time the Borrower does not have both a Moody's Rating and an S&P Rating, Level V Status shall exist.

In the event that a split occurs between the two ratings, then the Status corresponding to the lower of the two ratings shall apply. However, if the split is greater than one level, then the pricing shall be based upon the Status one level above the Status corresponding to the lower of the two ratings.

FORM OF OPINION OF COUNSEL TO THE BORROWER

[Date]

To each of the Lenders set forth
in Schedule A hereto

DTE Energy Company
The Detroit Edison Company
Michigan Consolidated Gas Company

Ladies and Gentlemen:

This opinion is furnished to you pursuant to (i) Section 3.01(h)(v) of each of the 364-Day and Three-Year Credit Agreements, dated as of October 25, 2002, among DTE Energy Company ("DTE"), the financial institutions from time to time parties thereto (the "DTE Lenders"), and Citibank, N.A., as agent for said DTE Lenders, Barclays Bank PLC and Banc One Capital Markets, Inc., as Co-Syndication Agents, and with Salomon Smith Barney Inc., as Lead Arranger and Sole Book Runner (the "DTE Credit Agreements"), (ii) Section 3.01(h)(v) of each of the 364-Day and Three-Year Credit Agreements, dated as of October 25, 2002, among The Detroit Edison Company ("DECO"), the financial institutions parties thereto (the "DECO Lenders") and Barclays Bank PLC, as agent for said DECO Lenders, Salomon Smith Barney Inc. and Banc One Capital Markets, Inc., as Co-Syndication Agents, and with Barclays Capital and Banc One Capital Markets, Inc., as Co-Lead Arrangers and Joint Book Runners (the "DECO Credit Agreements"), and (iii) Section 3.01(h)(v) of each of the 364-Day and Three-Year Credit Agreements, dated as of October 25, 2002, among Michigan Consolidated Gas Company ("MichCon"), the financial institutions parties thereto (the "MichCon Lenders", and together with the DTE Lenders and the DECO Lenders, the "Lenders") and Bank One, NA, as agent for said Lenders, Barclays Bank PLC and Salomon Smith Barney Inc., as Co-Syndication Agents, and with Banc One Capital Markets, Inc. and Barclays Capital, as Co-Lead Arrangers and Joint Book Runners (the "MichCon Credit Agreements", and together with the DTE Credit Agreements and the DECO Credit Agreements, the "Credit Agreements"). Terms defined in each Credit Agreement are used herein as therein defined.

I am the Associate General Counsel of DTE, and the Vice President and General Counsel of both DECO and MichCon, and have acted as counsel for each of the Borrowers in connection with the preparation, execution and delivery of the Loan Documents.

In that connection, I, in conjunction with the members of my staff, have examined:

(i) Each Loan Document, executed by each of the parties thereto.

14 SIDLEY AUSTIN BROWN & WOOD LLP


         (ii) The other documents furnished by each of the
Borrowers pursuant to Article III of each of the Credit
Agreements.

         (iii) The Restated Articles of Incorporation of DTE,
the Restated Articles of Incorporation of DECO, and the
Restated Articles of Incorporation of MichCon and all
amendments thereto (the "Charters").

         (iv) The By-Laws of each of the Borrowers and all
amendments thereto (the "By-Laws").

         (v) Certificates from the State of Michigan
attesting to the continued corporate existence and good
standing of each of the Borrowers.

I have also examined the originals, or copies certified to my satisfaction, of the documents listed in a certificate of a Financial Officer of each of the Borrowers, dated the date hereof (the "Certificate"), certifying that the documents listed in such certificate are all of the indentures, loan or credit agreements, leases, guarantees, mortgages, security agreements, bonds, notes and other agreements or instruments, and all of the orders, writs, judgments, awards, injunctions and decrees, that affect or purport to affect each Borrower's right to borrow money or each Borrower's obligations under the Loan Documents to which it is party. In addition, I have examined the originals, copies certified to my satisfaction, of such other corporate records of each Borrower, certificates of public officials and of officers of each Borrower, and agreements, instruments and other documents, as we have deemed necessary as a basis for the opinions expressed below. As to questions of fact material to such opinions, I have, when relevant facts were not independently established by me, relied upon certificates of public officials. I have assumed the due execution and delivery, pursuant to due authorization, of each of the Credit Agreements by the Lenders and the applicable Agent.

My opinions expressed below are limited to the law of the State of Michigan and the federal law of the United States.

Based upon the foregoing and upon such investigation as I have deemed necessary, I am of the following opinion:

1. Each of the Borrowers is a corporation duly organized, validly existing and in good standing under the laws of the State of Michigan.

2. The execution, delivery and performance by each of the Borrowers of the Loan Documents to which it is party, and the consummation of the transactions contemplated thereby, are within each Borrower's corporate powers, have been duly authorized by all necessary corporate action, and do not contravene (i) the Charters or the By-Laws of each Borrower or (ii) any law, rule or regulation applicable to each of the Borrowers (including, without limitation, Regulation X of the Board of Governors of the Federal Reserve System) or (iii) any contractual or legal restriction contained in any document listed in the Certificate or, to the best of my knowledge (after due inquiry), contained in any other similar document.

3. No authorization, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body or any other third party is required for the due

15 SIDLEY AUSTIN BROWN & WOOD LLP


execution, delivery, recordation, filing or performance by each Borrower of the Loan Documents to which each is a party, except such as have been obtained, including, in the case of DECO, the orders of the Federal Energy Regulatory Commission.

4. Each Loan Document has been duly executed and delivered on behalf of the Borrower thereto.

5. Except as may have been disclosed to you in the SEC Reports designated in the Certificate, to the best of my knowledge (after due inquiry) there are no pending or overtly threatened actions or proceedings affecting each Borrower or any of its Subsidiaries before any court, governmental agency or arbitrator that (i) could be reasonably likely to have a Material Adverse Effect or (ii) purport to affect the legality, validity, binding effect or enforceability of any Loan Documents or the consummation of the transactions contemplated thereby.

6. In a properly presented case, a Michigan court or a federal court sitting in the State of Michigan applying Michigan choice of law rules should give effect to the choice of law provisions of the Loan Documents and should hold that such Loan Documents are to be governed by the laws of the State of New York rather than the laws of the State of Michigan. In rendering the foregoing opinion, I note that by their terms the Loan Documents expressly select New York law as the laws governing their interpretation and that the Loan Documents governed by New York law were delivered by the parties thereto to the Agent in New York. The choice of law provisions of the Loan Documents are not voidable under the laws of the State of Michigan.

7. If, despite the provisions of Section 8.09 of each of the Credit Agreements wherein the parties thereto agree that the Loan Documents shall be governed by, and construed in accordance with, the laws of the State of New York, a court of the State of Michigan or a federal court sitting in the State of Michigan were to hold that the Loan Documents are governed by, and to be construed in accordance with the laws of the State of Michigan, the respective Loan Documents would be, under the laws of the State of Michigan, legal, valid and binding obligations of the applicable Borrower, enforceable against such Borrower in accordance with their respective terms.

8. Neither the Borrowers nor any of their Subsidiaries is an "investment company," or an "affiliated person" of, or "promoter" or "principal underwriter" for, an "investment company," as such terms are defined in the Investment Company Act of 1940, as amended; DECO is a "public utility company" and a "subsidiary company" of DTE, which is a "holding company" as such terms are defined in the Public Utility Holding Company Act of 1935, as amended (the "1935 Act"), and such "holding company" and DECO are currently exempt from the provisions of the 1935 Act (except Section 9 thereof); and MichCon is a "public utility company" and a "subsidiary company" of MichCon Holdings, Inc., which is a "holding company" and a "subsidiary company" of DTE Enterprises, Inc., which is a "holding company" and a "subsidiary company" of DTE, as such terms are defined in the 1935 Act, and such "holding companies" and MichCon are currently exempt from the provisions of the 1935 Act (except Section 9 thereof);

The opinions set forth above are subject to the following qualifications:

16 SIDLEY AUSTIN BROWN & WOOD LLP


                           (a) My opinion in paragraph 7 above as to
                  enforceability is subject to the effect of any applicable
                  bankruptcy, insolvency (including, without limitation, all
                  laws relating to fraudulent transfers), reorganization,
                  moratorium or similar law affecting creditors' rights
                  generally.

                           (b) My opinion in paragraph 7 above as to
                  enforceability is subject to the effect of general principles
                  of equity, including, without limitation, concepts of
                  materiality, reasonableness, good faith and fair dealing
                  (regardless of whether considered in a proceeding in equity or
                  at law).

                           (c) I express no opinion as to participation and the
                  effect of the law of any jurisdiction other than the State of
                  Michigan wherein any Lender may be located or wherein
                  enforcement of the Loan Documents may be sought that limits
                  the rates of interest legally chargeable or collectible.

                                                 Very truly yours,
